Isolated subcutaneous nontuberculous mycobacterial infection: a rare case initially mischaracterized as a soft tissue malignancy
Abstract
The occurrence of nontuberculous mycobacterial (NTM) infection is rare, and the involvement of the musculoskeletal system is even less common. However, the incidence of soft tissue and skin NTM infection is increasing, particularly in patients who undergo injections and minor surgical procedures. Given the non-specific clinical manifestations of NTM infection, the lack of knowledge among physicians regarding this rare infection could lead to inaccurate and delayed diagnosis. Herein, we present a case of an isolated subcutaneous NTM infection caused by Mycobacterium abscessus in the upper back of an immunocompetent 68-year-old woman. The clinical presentation, magnetic resonance imaging findings (including diffusion-weighted imaging), and pathologic findings of subcutaneous NTM infection are described and compared with those of tuberculosis and tumor presentations to provide a more accurate clinical picture for a differential diagnosis.

Avulsion fracture of an ossified pes anserinus tendon post-lateral patellar dislocation
Abstract
The pes anserinus is a common tendon comprising the tendinous insertions of the sartorius, gracilis, and semitendinosus muscles. It inserts at the anteromedial aspect of the tibia and plays a significant role in stabilization of the medial side of the knee joint. The current article presents a case with recurrent lateral patellar dislocations causing chronic stress along the medial knee stabilizers and consecutive enthesophyte formation at the insertion of the pes anserinus tendon that showed a transverse fracture upon a subsequent incident of traumatic lateral patellar dislocation. Avulsion injuries of the pes anserinus tendon are rarely encountered, and to our knowledge, association with recurrent lateral patellar dislocations has not been described before.

MRI in chronic groin pain: sequence diagnostic reliability compared to systematic surgical assessment
Abstract
Objective
To determine the diagnostic reliability of magnetic resonance imaging (MRI) sequences in chronic groin pain (CGP) compared to surgery and try to propose a suitable MRI protocol.
Materials and methods
Forty-three consecutive patients with resistant clinical CGP underwent a pre-surgical pelvis MRI. Eight MRI sequences were acquired: axial fast spin-echo T1-weighted (FSE T1), coronal FSE T1, axial-oblique (in symphysis plane) proton density weighted with fat saturation (PDFS), coronal PDFS, sagittal PDFS, axial FSE T1 with fat saturation and gadolinium enhancement (FSGE), coronal FSE T1 FSGE and axial FSE T1 with Valsalva maneuver (VM). These sequences were reviewed for pubic symphysis assessment, adductor longus (AL) tendon and abdominal wall (AW) injuries. The same surgeon operated on all of these patients (26 AL and 49 AW). Sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative prospective value (NPV) and accuracy of each sequence and combinations for AL or AW injuries were calculated in comparison to surgical findings.
Results
One hundred ninety-two sequences were obtained. Coronal T1 FSGE and axial T1 VM proved to be the most reliable sequences (accuracy: 91.67% in AL and 83.33% in AW). The best sequence combination was coronal T1, axial PDFS, sagittal PDFS and axial T1 VM (accuracy: 77.78%; Se: 100.00%, Sp: 69.23%, PPV: 55.56%, NPV: 100.00%).
Conclusion
MRI has 77.78% accuracy, 100.00% sensitivity, 69.23% specificity, 55.56% PPV and 100.00% NPV in evaluating CGP, with coronal T1-axial PDFS-sagittal PDFS-axial T1 VM as the optimal protocol in terms of diagnostic performance within a reasonable scan time. Diagnostic performance of MRI was examined in the evaluation of CGP using surgery as reference standard.

An intra-articular synovial lipoma of the hip, possibly causing osteoarthritis: a case report and review of the literature
Abstract
In this report, we present the case of an intra-articular synovial lipoma in a 58-year-old female with a coincident marked unilateral hip osteoarthritis. This patient suffered from right hip pain that developed gradually over 2 years. Physical examination noted decreased range of motion and evidence of impingement. MR and CT images showed an intra-articular fat-intense mass in the hip joint that was excised and confirmed as a synovial lipoma on histology. This case reveals that an intra-articular lipoma of the hip could be accompanied by pain or impingement and followed by hip osteoarthritis even in the absence of trauma.

MRI of the sacroiliac joints in spondyloarthritis: the added value of intra-articular signal changes for a ‘positive MRI’
Abstract
Objective
To determine if intra-articular signal changes at the sacroiliac joint space on MRI have added diagnostic value for spondyloarthritis, when compared to bone marrow edema (BME).
Materials and methods
A retrospective study was performed on the MRIs of sacroiliac joints of 363 patients, aged 16–45 years, clinically suspected of sacroiliitis. BME of the sacroiliac joints was correlated to intra-articular sacroiliac joint MR signal changes: high T1 signal, fluid signal, ankylosis and vacuum phenomenon (VP). These MRI findings were correlated with final clinical diagnosis. Sensitivity (SN), specificity (SP), likelihood ratios (LR), predictive values and post-test probabilities were calculated.
Results
BME had SN of 68.9%, SP of 74.0% and LR+ of 2.6 for diagnosis of spondyloarthritis. BME in absence of intra-articular signal changes had a lower SN and LR+ for spondyloarthritis (SN = 20.5%, LR+ 1.4). Concomitant BME and high T1 signal (SP = 97.2%, LR + = 10.5), BME and fluid signal (SP = 98.6%, LR + = 10.3) or BME and ankylosis (SP = 100%) had higher SP and LR+ for spondyloarthritis. Concomitant BME and VP had low LR+ for spondyloarthritis (SP = 91%, LR + =0.9). When BME was absent, intra-articular signal changes were less prevalent, but remained highly specific for spondyloarthritis.
Conclusion
Our results suggest that both periarticular and intra-articular MR signal of the sacroiliac joint should be examined to determine whether an MRI is 'positive' or 'not positive' for sacroiliitis associated with spondyloarthritis.

Hallux saltans due to stenosing tenosynovitis of flexor hallucis longus: dynamic sonography and arthroscopic findings
Abstract
Triggering of the toes is rare, with isolated cases reported in the literature involving predominantly the flexor hallucis longus (FHL) tendon, a condition known as "hallux saltans" (HS). We report the dynamic sonographic findings of a 42-year-old female with a 2-month history of ankle pain and triggering of right hallux, consistent with HS. Sonography demonstrated tenosynovitis and focal thickening of FHL at the level of hindfoot, with a fibrous band adjacent to the tendon. Dynamic ultrasound showed triggering and snapping of FHL tendon during hallux flexion and extension, respectively. We present comprehensive documentation of this rare entity, including sonographic still images and cine clips, as well as correlation with arthroscopic surgical findings.

Atypical lipomatous tumor of the hand with transformation to dedifferentiated liposarcoma: a case report
Abstract
Atypical lipomatous tumor/well-differentiated liposarcoma is the most common sarcoma of soft tissue in adults. We describe the clinical, radiologic, and pathologic features of an atypical lipomatous tumor arising within the soft tissue of the left hand of a 68-year-old female that underwent transformation to dedifferentiated liposarcoma and eventually metastasized. At initial presentation, imaging demonstrated an extensively calcified fatty soft tissue mass with displacement of the digits. Following biopsy and staged debulking, the patient subsequently developed local recurrence, dedifferentiation, and widespread metastases to the lungs, pancreas, bone, and soft tissues. To our knowledge, this is the first case of a cytogenetically proven atypical lipomatous tumor of the hand that has undergone dedifferentiation with widespread metastases.

Isolated avulsion fracture of the first metatarsal base at the peroneus longus tendon attachment: a case report
Abstract
Avulsion fractures of the first metatarsal (MT1) base at the peroneus longus (PL) tendon attachment are rare and may be undiagnosed during an emergency visit. If the injury is not treated properly, chronic pain or persistent impairment for inversion and plantar-flexion of the first ray may occur. This case report presents a 30-year-old woman who presented 10 weeks post trauma to a foot and ankle surgeon due to a swollen right midfoot with diffuse tenderness over the medial Lisfranc joint. Further evaluation showed an isolated avulsion fracture of the first metatarsal, which was undiagnosed during the emergent visit following the accident. In this case, the patient was successfully treated conservatively. The goal of this article is to raise awareness of this rare injury for radiologists and orthopedic surgeons.

Invasive Listeriosis of Intracardiac Device
Introduction. Listeria monocytogenes is a food-borne pathogen which can cause invasive infection in immunocompromised adults. Listeria has been known to cause infections during pregnancy and in older adults. Listeria endocarditis is a rare condition. A case of listeria-related intracardiac device infection is reported below. Case Report. A 74-year-old male with a past medical history of coronary artery disease, congestive cardiac failure, permanent atrial fibrillation status after nodal ablation, and placement of a biventricular pacemaker presented to the hospital with complaints of generalized fatigue. He was found to have listeria bacteremia, and transthoracic echocardiogram (TTE) showed pacemaker lead vegetation. The patient was treated with 6 weeks of vancomycin followed by oral suppression with amoxicillin. Discussion. Listeria can affect native valves, prosthetic valves, or nonvalvular intracardiac devices. The mean age of prosthetic valve endocarditis has been reported to be 67 years with male-to-female ratio 1.7 : 1 and mitral-to-aortic valve ratio 1.3 : 1. There have been case reports of listeria prosthetic valve endocarditis; however, there is paucity of literature on listeria-related pacemaker lead infection. Treatment is mostly a combination of penicillin and aminoglycosides for 4–6 weeks. Surgical removal of the infected device is preferred. Invasive listeriosis is a rare but fatal entity which should be identified and treated promptly to ensure a good outcome.

Serum magnesium and risk of incident heart failure in older men: The British Regional Heart Study
Abstract
To examine the association between serum magnesium and incident heart failure (HF) in older men and investigate potential pathways including cardiac function, inflammation and lung function. Prospective study of 3523 men aged 60–79 years with no prevalent HF or myocardial infarction followed up for a mean period of 15 years, during which 268 incident HF cases were ascertained. Serum magnesium was inversely associated with many CVD risk factors including prevalent atrial fibrillation, lung function (FEV1) and markers of inflammation (IL-6), endothelial dysfunction (vWF) and cardiac dysfunction [NT-proBNP and cardiac troponin T (cTnT)]. Serum magnesium was inversely related to risk of incident HF after adjustment for conventional CVD risk factors and incident MI. The adjusted hazard ratios (HRs) for HF in the 5 quintiles of magnesium groups were 1.00, 0.72 (0.50, 1.05), 0.85 (0.59, 1.26), 0.76 (0.52, 1.11) and 0.56 (0.36, 0.86) respectively [p (trend) = 0.04]. Further adjustment for atrial fibrillation, IL-6, vWF and FEV1 attenuated the association but risk remained significantly reduced in the top quintile (≥ 0.87 mmol/l) compared with the lowest quintile [HR 0.62 (0.40, 0.97)]. Adjustment for NT-proBNP and cTnT attenuated the association further [HR 0.70 (0.44, 1.10)]. The benefit of high serum magnesium on HF risk was most evident in men with ECG evidence of ischaemia [HR 0.29 (0.13, 0.68)]. The potential beneficial effect of high serum magnesium was partially explained by its favourable association with CVD risk factors. Further studies are needed to investigate whether serum magnesium supplementation in older adults may protect from the development of HF.

Functional Analysis of Hif1 Histone Chaperone in Saccharomyces cerevisiae
The Hif1 protein in the yeast Saccharomyces cerevisie is an evolutionarily conserved H3/H4-specific chaperone and a subunit of the nuclear Hat1 complex that catalyzes the acetylation of newly synthesized histone H4. Hif1, as well as its human homolog NASP, has been implicated in an array of chromatin-related processes including histone H3/H4 transport, chromatin assembly and DNA repair. In this study, we elucidate the functional aspects of Hif1. Initially we establish the wide distribution of Hif1 homologs with an evolutionarily conserved pattern of four tetratricopeptide repeats (TPR) motifs throughout the major fungal lineages and beyond. Subsequently, through targeted mutational analysis, we demonstrate that the acidic region that interrupts the TPR2 is essential for Hif1 physical interactions with the Hat1/Hat2-complex, Asf1, and with histones H3/H4. Furthermore, we provide evidence for the involvement of Hif1 in regulation of histone metabolism by showing that cells lacking HIF1 are both sensitive to histone H3 over expression, as well as synthetic lethal with a deletion of histone mRNA regulator LSM1. We also show that a basic patch present at the extreme C-terminus of Hif1 is essential for its proper nuclear localization. Finally, we describe a physical interaction with a transcriptional regulatory protein Spt2, possibly linking Hif1 and the Hat1 complex to transcription-associated chromatin reassembly. Taken together, our results provide novel mechanistic insights into Hif1 functions and establish it as an important protein in chromatin-associated processes.

Accounting for Genotype-by-Environment Interactions and Residual Genetic Variation in Genomic Selection for Water-Soluble Carbohydrate Concentration in Wheat
Abiotic stress tolerance traits are often complex and recalcitrant targets for conventional breeding improvement in many crop species. This study evaluated the potential of genomic selection to predict water-soluble carbohydrate concentration (WSCC), an important drought tolerance trait, in wheat under field conditions. A panel of 358 varieties and breeding lines constrained for maturity was evaluated under rainfed and irrigated treatments across two locations and two years. Whole-genome marker profiles and factor analytic mixed models were used to generate genomic estimated breeding values (GEBVs) for specific environments and environment groups. Additive genetic variance was smaller than residual genetic variance for WSCC, such that genotypic values were dominated by residual genetic effects rather than additive breeding values. As a result, GEBVs were not accurate predictors of genotypic values of the extant lines, but GEBVs should be reliable selection criteria to choose parents for intermating to produce new populations. The accuracy of GEBVs for untested lines was sufficient to increase predicted genetic gain from genomic selection per unit time compared to phenotypic selection if the breeding cycle is reduced by half by the use of GEBVs in off-season generations. Further, genomic prediction accuracy depended on having phenotypic data from environments with strong correlations with target production environments to build prediction models. By combining high-density marker genotypes, stress-managed field evaluations, and mixed models that model simultaneously covariances among genotypes and covariances of complex trait performance between pairs of environments, we were able to train models with good accuracy to facilitate genetic gain from genomic selection.

Studying embryotoxicity of petroleum products for carp fish family
Abstract
To study the embryotoxicity of the oil fraction Karakuduk locality (Kazakhstan, oil deposit) for zebrafish Danio rerio (family Cyprinidae), in the conditions of the experiment. The method of breeding fishes of Danio rerio, receiving, and incubating zebrafish in vitro. Experiments have been carried out on the development of Danio rerio embryos in the oil-bearing fraction (Karakuduk locality) in various in vitro concentrations. The paper presents the results of experiments on exposure zebrafish embryos (Danio rerio) oil fractions in different concentrations and shows data on mortality of embryos and embryonic development violations. The originality of studying embryotoxicity of petroleum products for Cyprinidae fish family is that the object of our experiment is the most vulnerable age group in the population-fish larvae. Due to investigations, number of eggs could exactly determine the vitality of the fish population in general and can counter the number of the population through a certain period. Following the epidemic of mass mortality of caviar and larvae from oil pollution, the toxicant acts in the role of the immunosuppressive agent. Thus, it leads to the reduction of resistance to various infections with the reduction of the variability of even slight temperature and salinity fluctuations.

Molecular characterization of qnrVC and their novel alleles in Vibrio spp. isolated from food products in China [PublishAheadOfPrint]
This study reported the prevalence of qnrVC genes in 74 ciprofloxacin-resistant Vibrio spp. isolates. Two novel functional qnrVC alleles, qnrVC8 and qnrVC9, sharing 98% and 99% nucleotide similarity with qnrVC6 and qnrVC7 respectively, were identified. Our findings suggested that carriage of qnrVC alleles, together with target mutations in gyrA and parC genes, may contribute to development of fluoroquinolone resistance in Vibrio species, posing serious threat to public health.

Unexpected Replication Boost by Simeprevir for Simeprevir-resistant Variants in Genotype 1a Hepatitis C Virus [PublishAheadOfPrint]
Simeprevir is a novel NS3/4A protease inhibitor (PI) of hepatitis C virus (HCV). The baseline polymorphism NS3-Q80K is frequently observed in genotype (gt) 1a HCV and often associated with treatment failure in simeprevir-containing regimens. We aimed to elucidate mechanisms of treatment failure due to NS3-Q80K. We included a Q80R mutation in our study and generated a series of Huh-7.5 cells, each of which harbored either wild-type gt 1a H77S.3 or one of the variants, Q80K or Q80R. The cells were cultured with increasing concentrations of simeprevir, and NS3 domain sequences were determined. The mutations identified by sequence analyses were subsequently introduced into H77S.3. The sensitivity of each mutant to NS3/4A PIs simeprevir, asunaprevir, grazoprevir, and paritaprevir was analyzed. We introduced the mutations into gt 1b N.2 and compared the sensitivity to simeprevir with that in gt 1a H77S.3. While simeprevir treatment selected mutations at residue D168, such as D168A/V in the wild-type virus, an additional mutation at residue R155, R155K, was selected in Q80K/R variants at simeprevir concentrations lower than 2.5 μM. Sensitivity analyses showed that simeprevir concentrations of less than 1 μM significantly boosted the replication of Q80K/R+R155K variants. Interestingly, this boost was not observed with the other NS3/4A PIs, and not in Q80R+R155Q/G/T/W variants or gt 1b. The boosted replication of Q80K+R155K by simeprevir could be related to treatment failure in simeprevir-containing antiviral treatments in gt 1a HCV-infected patients with the NS3-Q80K polymorphism. This result provides a new insight into how resistance-associated variants can cause treatment failure.

The Genetic Polymorphism UGT1A4*3 Is Associated with Low Posaconazole Plasma Concentrations in Hematological Malignancy Patients Receiving the Oral Suspension [PublishAheadOfPrint]
The metabolism of posaconazole is mediated mainly by uridine 5' -diphospho-glucuronosyltransferase (UGT) enzymes, especially the UGT1A4. The aim of this study was to investigate the effects of genetic polymorphisms on the posaconazole plasma concentration (PPC). This prospective study was conducted from September 2014 to August 2016. We enrolled patients with acute myeloid leukemia or myelodysplastic syndrome treated with posaconazole oral suspension (200 mg) three times daily for fungal prophylaxis. The multi-drug resistance gene 1 3435C>T and 2677G>T/A variations, and UGT1A4*3 were examined by direct sequencing of DNA from peripheral whole blood samples. We defined poor absorbers as those with PPCs <200 ng/mL and the optimal PPC as ≥700 ng/mL on day 8. The associations between genetic polymorphisms and the PPC were evaluated using multivariate logistic regression analysis including clinical variables. In the study period, 132 patients were enrolled. Six patients (4.5%) were defined as poor absorbers and 49 patients (37.1%) did not reach the optimal PPC on day 8. In multivariate analysis, the independent risk factors for a poor absorber were at least one UGT1A4*3 allele (adjusted odds ratio [lsqb]aOR[rsqb], 18.81; 95% confidence interval [lsqb]CI[rsqb], 1.09-324.44; p = 0.043) and poor oral food intake (aOR per -100 kcal, 1.44; 95% CI, 1.04-1.99; p = 0.029). There was no statistically significant association between the genetic polymorphisms and reaching the optimal PPC on day 8. The UGT1A4*3 polymorphism is an independent risk factor for being a poor absorber of posaconazole oral suspension in patients with hematologic malignancies.

Characterising blood stage antimalarial drug minimum inhibitory concentrations in vivo using reinfection patterns [PublishAheadOfPrint]
The minimum inhibitory concentration (MIC) is an essential quantitative measure of the asexual blood stage effect of an antimalarial drug. In areas of high malaria transmission, and thus frequent individual infection, patients who are treated with slowly eliminated antimalarials become reinfected as drug concentrations decline. In the frequent relapse forms of P. vivax and in P. ovale malaria, recurrent infection occurs from relapses which begin to emerge from the liver approximately two weeks after the primary illness. An important determinant of the interval from starting treatment of a symptomatic infection to the patency of these recurrent infections is the in vivo concentration-response relationship and thus the in vivo MIC. Using mechanistic knowledge of parasite asexual replication and the pharmacokinetic and pharmacodynamic properties of the antimalarial drugs, a generative statistical model was derived which relates the concentration-response relationship to time of reinfection patency. This model was used to estimate the in vivo MIC of chloroquine in the treatment of Plasmodium vivax malaria.

Spread of clonally related Escherichia coli harboring an IncA/C1 plasmid encoding IMP-8 and its recruitment into an unrelated MCR-1-containing isolate [PublishAheadOfPrint]
Ten IMP-8-producing Escherichia coli isolates were recovered from the surveillance cultures of a neonatal intensive care unit, of which eight were clonally related. A 168.2-kb-blaIMP-8 plasmid was fully sequenced, and it corresponded to the recently described IncA/C1-ST13. This plasmid was detected in all isolates, even in those no clonally related. One unrelated isolate was also resistant to colistin and positive for mcr-1. This marker was located in a 62.7-kb-IncI2 plasmid, which was also fully sequenced.

HC2091 kills Mycobacterium tuberculosis by targeting the MmpL3 mycolic acid transporter [PublishAheadOfPrint]
Tuberculosis, caused by the intracellular pathogen Mycobacterium tuberculosis (Mtb), is a deadly disease that requires a long course of treatment. The emergence of drug resistant strains has driven efforts to discover new small molecules that can kill the bacterium. Here we report characterizations of the compound HC2091 that kills Mtb in a time- and dose-dependent manner in vitro, as well as inhibiting Mtb growth in macrophages. Whole genome sequencing of spontaneous resistant mutants to HC2091 identified single nucleotide variants in the mmpL3 mycolic acid transporter gene. HC2091 resistant mutants do not exhibit cross-resistance with the well-characterized MmpL3 inhibitor SQ109, suggesting a distinct mechanism of interaction with MmpL3. Additionally, HC2091 does not modulate bacterial membrane potential or kill non-replicating Mtb, thus acting differently from other known MmpL3 inhibitors. RNA-seq transcriptional profiling and lipid profiling of Mtb treated with HC2091 or SQ109 show that both compounds target a similar pathway. HC2091 has a dissimilar chemical structure from previously described MmpL3 inhibitors, supporting that HC2091 is a new class of MmpL3 inhibitor.

Antimicrobial and antibiofilm efficacy of graphene oxide against chronic wound microorganisms [PublishAheadOfPrint]
Chronic wounds represent an increasing problem worldwide. Graphene oxide (GO) has been reported to exhibit strong antibacterial activity towards both Gram-positive and Gram-negative bacteria. The aim of this work was to investigate the in vitro antimicrobial and antibiofilm efficacy of GO against wound pathogens. Staphylococcus aureus PECHA 10, Pseudomonas aeruginosa PECHA 4 and Candida albicans X3 clinical isolates were incubated with 50 mg/L of GO for 2 and 24 h to evaluate the antimicrobial effect. Optical and Atomic force microscopy images were performed to visualize the GO effect on microbial cells. Moreover, the antibiofilm effect of GO was tested on biofilms both in formation and mature. When compared to the respective time controls, GO significantly reduced the S. aureus growth both at 2 and 24 h in a time dependent way, and displayed a bacteriostatic effect in respect to the GO t=0; an immediate (after 2 h) slowdown of bacterial growth was detected for P. aeruginosa whereas a tardive effect (after 24 h) was recorded for C. albicans. Atomic force microscopy images showed the complete wrapping of S. aureus and C. albicans with GO sheets that explains its antimicrobial activity. Moreover, significant inhibition of biofilm formation and a reduction of mature biofilm were recorded for each detected microorganism. The antibacterial and antibiofilm properties of GO against chronic wound microrganisms make it an interesting candidate to incorporate into wound bandages to treat and/or prevent microbial infections.

Plasticity of aminoglycoside binding to antibiotic kinase APH(2")-Ia [PublishAheadOfPrint]
APH(2")-Ia aminoglycoside resistance enzyme forms the C-terminal domain of the bifunctional AAC(6')-Ie/APH(2")-Ia enzyme and confers high-level resistance to natural 4,6-disubstituted aminoglycosides. In addition, reports have suggested that the enzyme can phosphorylate 4,5-disubstituted compounds and aminoglycosides with substitutions at the N1-position. Previously determined structures of the enzyme with aminoglycosides bound have not indicated how these non-canonical substrates could bind and be modified by the enzyme. We carried out crystallographic studies to directly observe the interaction of these compounds with the aminoglycoside-binding site and probe the means by which these non-canonical substrates interact with the enzyme. We find that APH(2")-Ia maintains a preferred mode of binding aminoglycosides using the conserved neamine rings when possible, with flexibility that allows it to accommodate additional rings. However, if this binding mode is made impossible because of additional substitutions to the standard 4,5- or 4,6-disubstituted aminoglycoside architecture as in lividomycin A or the N1-substituted aminoglycosides, it is still possible for these aminoglycosides to bind to the antibiotic-binding site, using alternate binding modes, explaining the low rates of non-canonical phosphorylation activities seen in enzyme assays. Furthermore, structural studies of a clinically-observed arbekacin-resistant mutant of APH(2")-Ia reveals an altered aminoglycoside binding site that can stabilize an alternative binding mode for N1-substituted aminoglycosides. This mutation could alter and expand the aminoglycoside resistance spectrum of the wildtype enzyme in response to newly developed aminoglycosides.

Amikacin Inhalation as Salvage Therapy for Refractory Nontuberculous Mycobacterial Lung Disease [PublishAheadOfPrint]
Although guidelines recommend amikacin (AMK) inhalation therapy for difficult-to-treat nontuberculous mycobacterial lung disease (NTM-LD), data are limited regarding the safety and clinical efficacy of this salvage therapy. We retrospectively evaluated treatment outcomes of 77 patients with refractory NTM-LD caused by Mycobacterium abscessus complex (MABC) or M. avium complex (MAC) who initiated AMK inhalation therapy between February 2015 and June 2016. MABC was the most common etiology (n = 48, 62%), followed by MAC (n = 20, 26%) and mixed infections (n = 9, 12%). Macrolide resistance and baseline AMK resistance were identified in 63 (82%) patients and five (6%) patients, respectively. Twelve months after AMK inhalation therapy, 49% of patients had symptomatic improvement, whereas 42% had radiologic improvement. Sputum negative culture conversion occurred in 14 (18%) patients, and the culture conversion rate was higher in patients infected with macrolide-susceptible isolates (7/14, 50%) than with macrolide-resistant isolates (7/63, 11%, P = 0.003). Significant decreases in sputum semiquantitative culture positivity occurred after AMK inhalation therapy (P < 0.001). On multivariate analysis, sputum culture conversion was associated with mixed infections (P = 0.009), a forced expiratory volume in one second of greater than 60% (P = 0.008), and with the absence of macrolide resistance (P = 0.003). Thirty-eight percent of patients experienced adverse effects, with ototoxicity (n = 15) most common. AMK inhalation salvage therapy may improve treatment responses in some patients with refractory NTM-LD. However, considering the common adverse effects, further evaluation of optimal dosage and intervals for AMK inhalation is needed.

Triclosan is an aminoglycoside adjuvant for the eradication of Pseudomonas aeruginosa biofilms [PublishAheadOfPrint]
One of the most important clinical obstacles in cystic fibrosis (CF) is antibiotic treatment failure due to biofilms produced by Pseudomonas aeruginosa. The ability of this pathogen to survive eradication by tobramycin and pathoadapt into a hyper-biofilm state leading to chronic infections is key to its success. Retrospective studies have demonstrated that preventing this pathoadaptation by improving eradication is essential to extend the lives of CF patients. To identify adjuvants that enhance tobramycin eradication of P. aeruginosa, we performed a high-throughput screen of 6,080 compounds from four drug repurposing libraries. We identified that the Food and Drug Administration (FDA) approved compound, triclosan, combined with tobramycin resulted in a 100-fold reduction of viable cells within biofilms at six hours, but neither compound alone had significant antimicrobial activity against biofilms. This synergistic treatment significantly accelerated killing of biofilms compared to tobramycin treatment alone, and the combination was effective against 6/7 CF clinical isolates compared to tobramycin treatment alone including a tobramycin resistant strain. Further, triclosan and tobramycin killed persister cells, causing a 100-fold reduction by 8-hrs and complete eradication by 24-hrs. Triclosan also enhances tobramycin killing of multiple Burkholderia cenocepacia and Staphylococcus aureus clinical isolates grown as biofilms. Additionally, triclosan synergized with other aminoglycosides such as gentamicin or streptomycin. Triclosan is a well-tolerated aminoglycoside adjuvant shown to be safe for human use that could improve treatment of biofilm-based infections.

Genetic diversity among S. aureus isolates showing oxacillin and/or cefoxitin resistance not linked to the presence of mec genes [PublishAheadOfPrint]
Methicillin-resistant Staphylococcus aureus isolates lacking mec-genes (n=32) collected from Belgian hospitals were characterized for their β-lactamase production and the presence of mutations in pbp-genes, the pbp4-promotor and genes (gdpP, yjbH) involved in PBP4-overproduction. Twelve isolates were β-lactamase hyperproducers (BHP), while 12 non-BHPs isolates may produce an incomplete GdpP protein. Most isolates showed nucleotide missense mutations at pbp genes. Few isolates showed also mutations at the pbp4-promoter.

Modeling and Simulation of Pretomanid Pharmacokinetics in Pulmonary Tuberculosis Patients [PublishAheadOfPrint]
Pretomanid is a nitroimidazole antibiotic in late phase clinical testing as a component of several novel antituberculosis (anti-TB) regimens. A population pharmacokinetic model for pretomanid was constructed using a Bayesian analysis of data from two phase 2 studies, PA-824-CL-007 and PA-824-CL-010, conducted with newly diagnosed adult (median age 27 years) pulmonary TB patients in Cape Town, South Africa. Combined, these studies included 63 males and 59 females administered once daily oral pretomanid doses of 50, 100, 150, 200, 600, 1000, or 1200 mg for 14 days. The observed pretomanid concentration-time profiles for all tested doses were described by a one-compartment model with first-order absorption and elimination, and a sigmoidal bioavailability dependent on dose, time, and predose fed state. Allometric scaling with body weight (normalized to 70 kg) was used for volume of distribution and clearance, with scaling exponents of 1 and 3/4, respectively. The posterior population geometric means for clearance and volume of distribution allometric constants were 4.8±0.2 L/h and 130±5 L, respectively, and 450±50 mg for the half-maximum effect dose for reduction of bioavailability. Interindividual variability, described by percent coefficient of variation, was 32±3% for clearance, 17±4% for volume of distribution, and 74±9% for half-maximum effect dose. This model provides a dose-exposure relationship for pretomanid in adult TB patients, with potential applications to dose selection in individuals and to further clinical testing of novel pretomanid-containing anti-TB regimens.

SOURCE OF THE FITNESS DEFECT IN RIFAMYCIN-RESISTANT M. TUBERCULOSIS RNA POLYMERASE AND THE MECHANISM OF COMPENSATION BY MUTATIONS IN THE {beta}'-SUBUNIT [PublishAheadOfPrint]
Mycobacterium tuberculosis (MTB) is a critical threat to human health due to the increased prevalence of rifampin resistance (RMPR). Fitness defects have been observed in RMPR mutants having amino acid substitutions in the β-subunit of RNA polymerase (RNAP). In clinical isolates, this fitness defect can be ameliorated by the presence of secondary mutations in the double-psi β-barrel (DPBB) domain of the β'-subunit of RNAP. To identify factors contributing to the fitness defects observed in vivo, several in vitro RNA transcription assays were utilized to probe initiation, elongation, termination, and 3' -RNA hydrolysis with the wild-type and RMPR MTB RNAPs. We found that the less prevalent RMPR mutants exhibit significantly poorer termination efficiencies relative to wild-type, an important factor for proper gene expression. We also found that several mechanistic aspects of transcription of the RMPR mutant RNAPs are impacted relative to wild-type. For the clinically most prevalent, βS450L mutant, these defects are mitigated by the presence of secondary/compensatory mutations in the DPBB domain of the β'-subunit.

Immunogenomic analyses of advanced serous ovarian cancer reveal immune score is a strong prognostic factor and an indicator of chemo-sensitivity
Purpose: Ovarian cancer is one of the first human cancers for which in situ immune response was reported to be important for the clinical outcome. To elucidate the mechanistic relationship between immune repertoire and cancer genotype in ovarian cancer, the development of a well-defined immune score for ovarian cancer is required. Experimental Design: From a collection of 2,203 patient samples of advanced ovarian cancer from public available resources, we evaluated the prognostic values for a compendium of immune marker genes and proposed an immune score. The relationships between immune score, tumor-infiltrating immune cells, cancer genotypes and their impact on patient outcome were characterized. Results: Loss of chemokine and IFN- pathway genes is frequent in ovarian cancer and is significantly associated with low immune score and poor outcome. Chemotherapy can increase the immune score of tumors by inducing the expression of IFN- inducible chemokines. High immune score is significantly associated with BRCA1/2 mutation status and the response to chemotherapy. Multivariate analysis revealed that immune score is a strong predictor of patient survival and the response to immunotherapy. Conclusions: Our results reveal the drivers of the immune repertoire of advanced ovarian cancer and demonstrate the importance of immune score as an independent prognostic signature and a potent indicator of intratumoral immune status.

Accuracy, Safety, and Reliability of Novel Phase I Trial Designs
A number of novel model-based and model-assisted designs have been proposed to find the maximum tolerated dose (MTD) in phase I clinical trials, but their differences and relative pros and cons are not clear to many practitioners. We review three model-based designs, including the continual reassessment method (CRM), dose escalation with overdose control (EWOC), and Bayesian logistic regression model (BLRM), and three model-assisted designs, including the modified toxicity probability interval (mTPI), Bayesian optimal interval (BOIN), and keyboard designs. We conduct numerical studies to assess their accuracy, safety and reliability, and the practical implications of various empirical rules used in some designs, such as skipping a dose and imposing overdose control. Our results show that the CRM outperforms EWOC and BLRM with higher accuracy of identifying the MTD. For the CRM, skipping a dose is not recommended as it substantially increases the chance of overdosing patients, while providing limited gain for identifying the MTD. EWOC and BLRM appear excessively conservative. They are safe, but have relatively poor accuracy of finding the MTD. The BOIN and keyboard designs have similar operating characteristics, outperforming the mTPI, but the BOIN is more intuitive and transparent. The BOIN yields competitive performance comparable to the CRM, but is simpler to implement and free of the issue of irrational dose assignment caused by model misspecification, thereby providing an attractive approach for designing phase I trials.

Prospective clinical trial of ixazomib, dexamethasone and rituximab as primary therapy in Waldenström macroglobulinemia
Introduction: Proteasome inhibition is of proven efficacy in patients with Waldenström macroglobulinemia (WM). However, WM remains incurable with standard treatments. Novel agents, safe and effective, are needed. Methods: We designed a prospective phase II study evaluating the combination of ixazomib, dexamethasone and rituximab (IDR) as primary therapy in symptomatic patients with WM. Protocol therapy consisted of oral ixazomib, 4 mg, with intravenous or oral dexamethasone, 20 mg, on days 1, 8 and 15 every 4 weeks for induction cycles 1 and 2, and in combination with intravenous rituximab, 375 mg/m2, on day 1, every 4 weeks for cycles 3 to 6. Maintenance therapy followed 8 weeks later with IDR given every 8 weeks for 6 cycles. Results: Twenty-six patients were enrolled. All patients had the MYD88 L265P mutation, and 15 patients (58%) had a CXCR4 mutation. The median time to response was 8 weeks, which was longer (12 weeks) in WM patients with CXCR4 mutations (p=0.03). The overall response rate was 96% and the major response rate was 77%. With a median follow-up of 22 months, the median progression-free survival was not reached. Grade ≥2 adverse events reported in >1 patient included infusion-related reactions (19%), rash (8%) and insomnia (8%). Conclusion: IDR offers a highly effective and well tolerated, neuropathy-sparing regimen for primary therapy in patients with WM. This trial is registered at www.clinicaltrials.gov under ID NCT02400437.

Integrated genomic and immunophenotypic classification of pancreatic cancer reveals three distinct subtypes with prognostic/predictive significance
Purpose: Current clinical classification of pancreatic ductal adenocarcinoma (PDAC) is unable to predict prognosis or response to chemo- or immunotherapy and does not take into account the host reaction to PDAC-cells. Our aim is to classify PDAC according to host- and tumor-related factors into clinically/biologically relevant subtypes by integrating molecular and microenvironmental findings. Experimental Design: A well-characterized PDAC-cohort (n=110) underwent next-generation sequencing with a hotspot cancer panel, while Next-generation Tissue-Microarrays were immunostained for CD3, CD4, CD8, CD20, PD-L1, p63, hyaluronan-mediated motility receptor (RHAMM) and DNA mismatch-repair proteins. Previous data on FOXP3 were integrated. Immune-cell counts and protein expression were correlated with tumor-derived driver mutations, clinicopathologic features (TNM 8. 2017), survival and epithelial-mesenchymal-transition (EMT)-like tumor budding. Results: Three PDAC-subtypes were identified: the "immune-escape" (54%), poor in T- and B-cells and enriched in FOXP3+Tregs, with high-grade budding, frequent CDKN2A- , SMAD4- and PIK3CA-mutations and poor outcome; the "immune-rich" (35%), rich in T- and B-cells and poorer in FOXP3+Tregs, with infrequent budding, lower CDKN2A- and PIK3CA-mutation rate and better outcome and a subpopulation with tertiary lymphoid tissue (TLT), mutations in DNA damage response genes (STK11, ATM) and the best outcome; and the "immune-exhausted" (11%) with immunogenic microenvironment and two subpopulations: one with PD-L1-expression and high PIK3CA-mutation rate and a microsatellite-unstable subpopulation with high prevalence of JAK3-mutations. The combination of low budding, low stromal FOXP3-counts, presence of TLTs and absence of CDKN2A-mutations confers significant survival advantage in PDAC-patients. Conclusions:Immune host responses correlate with tumor characteristics leading to morphologically recognizable PDAC-subtypes with prognostic/predictive significance.

Interferon-stimulated genes are involved in cross-resistance to radiotherapy in tamoxifen-resistant breast cancer
Purpose: Treatment resistance is a main cause of adverse disease outcome in breast cancer patients. Here we aimed to investigate common features in tamoxifen-resistant and radioresistant breast cancer, since tamoxifen-resistant breast cancer cells are cross-resistant to irradiation in vitro. Experimental Design: RNA sequencing of tamoxifen-resistant and radioresistant breast cancer cells was performed and validated by quantitative PCR. Pathways were further investigated in vitro and in breast cancer patient cohorts to establish their relation with treatment resistance. Results: Both tamoxifen-resistant and radioresistant breast cancer cells had increased expression levels of genes involved in type I IFN signaling compared to non-resistant cells. IFN-stimulated genes (ISGs) were induced in a dose-dependent and time-dependent manner after tamoxifen treatment and irradiation. Tamoxifen treatment also led to ssDNA presence in the cytoplasm, which is known to induce expression of ISGs, a phenomenon that has already been described for irradiation. Moreover, in a breast cancer patient cohort high expression levels of ISGs were found in the primary tumor in around half of the patients. This was associated with a tumor infiltrating lymphocyte expression signature, although the ISGs were also expressed by the tumor cells themselves. Importantly, the expression of ISGs correlated to outcome in breast cancer patients treated with adjuvant tamoxifen or radiotherapy, but not in systemically untreated patients or chemotherapy-treated patients. Conclusions: Our data indicate that expression of ISGs by tumor cells is involved in acquired, treatment-induced resistance to tamoxifen and radiotherapy, and might play a role in intrinsic resistance via interaction with tumor infiltrating lymphocytes.

Differential effects of estrogen receptor beta isoforms on glioblastoma progression
The estrogen receptor beta (ERβ) functions as a tumor suppressor in glioblastoma cells (GBM). However, the in vivo significance of endogenous ERβ and the roles of its isoforms in GBM are incompletely understood. Using ERβ isoform-specific PCR screening, we found that GBM cells predominantly express ERβ1 and ERβ5, along with low levels of ERβ2 and ERβ4. We observed greater ERβ5 expression in higher grades of glioma than in lower grades. In CRISPR-based ERβ knockout (KO) cells and ERβ KO cells uniquely expressing ERβ1, ERβ1 significantly reduced proliferation. Compared to parental GBM cells, ERβ KO cells exhibited high migratory and invasive potentials, and re-expression of ERβ1 resulted in the reduction of this phenotype. Interestingly, ERβ5 expression increased foci formation and anchorage-independent growth of NIH3T3 cells and increased motile structure formation, including filopodia and ruffles in GBM cells. Only ERβ1-expressing tumors resulted in longer mouse survival. RNA-Seq analysis revealed unique pathways modulated by ERβ1 and ERβ5. Compared to ERβ KO cells, ERβ1 cells exhibited lower activation of mTOR signaling molecules, including p-mTOR, p-S6K, and p-S6; and ERβ5-expressing cells had enhanced mTOR downstream signaling. Unique proteins including several that function as regulators of mTOR, immunomodulatory, and apoptosis pathways bound to ERβ1 and ERβ5 isoforms. Our work confirms the tumor suppressive potential of ERβ1 and reveals the acquired oncogenic ability of ERβ5 in GBM cells. ERβ isoform status and their unique interactions with oncogenic pathways may have important implications in GBM progression.

Sustained adrenergic signaling promotes intratumoral innervation through BDNF induction
Mounting clinical and preclinical evidence supports a key role for sustained adrenergic signaling in the tumor microenvironment as a driver of tumor growth and progression. However, the mechanisms by which adrenergic neurotransmitters are delivered to the tumor microenvironment are not well understood. Here we present evidence for a feedforward loop whereby adrenergic signaling leads to increased tumoral innervation. In response to catecholamines, tumor cells produced brain-derived neurotrophic factor (BDNF) in an ADRB3/cAMP/Epac/JNK-dependent manner. Elevated BDNF levels in the tumor microenvironment increased innervation by signaling through host neurotrophic receptor tyrosine kinase 2 (TrkB) receptors. In cancer patients, high tumor nerve counts were significantly associated with increased BDNF and norepinephrine levels and decreased overall survival. Collectively, these data describe a novel pathway for tumor innervation with resultant biological and clinical implications.

Premenstrual syndrome and alcohol consumption: a systematic review and meta-analysis
Objective
Premenstrual syndrome (PMS) is a very common disorder worldwide which carries an important economic burden. We conducted a systematic review and a meta-analysis to assess the role of alcohol in the occurrence of PMS.
MethodsWe searched MEDLINE, EMBASE, the five regional bibliographic databases of the WHO, the Proceedings database and the Open Access Thesis and Dissertations (OATD) from inception to May 2017. We also reviewed the references of every article retrieved and established personal contact with researchers to trace further publications or reports. We did not include any language limitations. Studies were included if: (1) they presented original data from cohort, case-control or cross-sectional studies, (2) PMS was clearly defined as the outcome of interest, (3) one of the exposure factors was alcohol consumption, (4) they provided estimates of odds ratios, relative risks, or any other effect measure and their confidence intervals, or enough data to calculate them.
ResultsWe identified 39 studies of which 19 were eligible. Intake of alcohol was associated with a moderate increase in the risk of PMS (OR=1.45, 95% CI: 1.17 to 1.79). Heavy drinking yielded a larger increase in the risk than any drinking (OR=1.79, 95% CI: 1.39 to 2.32).
DiscussionOur results suggest that alcohol intake presents a moderate association with PMS risk. Future studies should avoid cross-sectional designs and focus on determining whether there is a threshold of alcohol intake under which the harmful effect on PMS is non-existent.

Trends, geographical variation and factors associated with prescribing of gluten-free foods in English primary care: a cross-sectional study
Objectives
There is substantial disagreement about whether gluten-free foods should be prescribed on the National Health Service. We aim to describe time trends, variation and factors associated with prescribing gluten-free foods in England.
SettingEnglish primary care.
ParticipantsEnglish general practices.
Primary and secondary outcome measuresWe described long-term national trends in gluten-free prescribing, and practice and Clinical Commissioning Group (CCG) level monthly variation in the rate of gluten-free prescribing (per 1000 patients) over time. We used a mixed-effect Poisson regression model to determine factors associated with gluten-free prescribing rate.
ResultsThere were 1.3 million gluten-free prescriptions between July 2016 and June 2017, down from 1.8 million in 2012/2013, with a corresponding cost reduction from £25.4 million to £18.7 million. There was substantial variation in prescribing rates among practices (range 0 to 148 prescriptions per 1000 patients, IQR 7.3–31.8), driven in part by substantial variation at the CCG level, likely due to differences in prescribing policy. Practices in the most deprived quintile of deprivation score had a lower prescribing rate than those in the highest quintile (incidence rate ratio 0.89, 95% CI 0.87 to 0.91). This is potentially a reflection of the lower rate of diagnosed coeliac disease in more deprived populations.
ConclusionGluten-free prescribing is in a state of flux, with substantial clinically unwarranted variation between practices and CCGs.

Decorin modified umbilical cord mesenchymal stem cells (MSCs) attenuate radiation induced lung injuries via regulating inflammation, fibrotic factors and immune responses
Effective strategies are still lack for treating RILI. In experimental RILI model, we found MSCs.DCNcould home to injured lung tissues and produced decorin protein. Then, MSCs secreted cytokines to attenuate inflammation, regulated apoptosis and proliferation to promote tissue repair, and modulated pro-fibrotic factors to inhibit fibrosis. Secreted decorin protein inhibited pro-inflammatory and pro-fibrotic factors to enhance functions of MSCs. Therefore, MSCs.DCN might be a potential strategy for treating RILI.

In vivo validation of Elekta’s Clarity Autoscan® for ultrasound-based intrafraction motion estimation of the prostate during radiotherapy
The manuscript describes an in vivo validation of the Elekta Clarity Autoscan® system for estimating intrafraction prostate motion during radiotherapy. Intrafraction motion was estimated using Autoscan. These 3D motion estimates were used to estimate intraprostatic fiducial marker positions in 2D portal images. Estimated positions were compared to the actual portal imaged marker positions. Clarity monitored intrafraction motion with an accuracy of 0.6 mm, which is comparable to other motion monitoring systems used in radiotherapy.

Achieving Gender Equity in Physician Compensation and Career Advancement: A Position Paper of the American College of Physicians
Women comprise more than one third of the active physician workforce, an estimated 46% of all physicians-in-training, and more than half of all medical students in the United States. Although progress has been made toward gender diversity in the physician workforce, disparities in compensation exist and inequities have contributed to a disproportionately low number of female physicians achieving academic advancement and serving in leadership positions. Women in medicine face other challenges, including a lack of mentors, discrimination, gender bias, cultural environment of the workplace, imposter syndrome, and the need for better work–life integration. In this position paper, the American College of Physicians summarizes the unique challenges female physicians face over the course of their careers and provides recommendations to improve gender equity and ensure that the full potential of female physicians is realized.

Eliminating Alcohol-Impaired Driving Fatalities: What Can Be Done?
https://ift.tt/2FMFi0E
The Short-Lived Epidemic of Botulism From Commercially Canned Foods in the United States, 1919 to 1925
In 1919, three deadly outbreaks of botulism caused by consumption of canned olives packed in California captured national headlines. In all of the outbreaks, which occurred in separate locales, unsuspecting people died after consuming tainted food during a banquet or family meal. The press's sensational portrayal of canned food as hazardous aroused alarm among consumers at a time when commercial canning was becoming more common. Intent on restoring the image of their product as safe and wholesome, canning industry leaders funded a "botulism commission" of scientific experts in 1919 to investigate how to systematically eliminate the threat of botulism that had imperiled their business. The commissioners identified the scientific reasons for the outbreaks, and on the basis of their findings, the California Department of Public Health issued explicit recommendations for sterilization procedures intended to ensure safety. However, the department did not mandate inspections for all canneries. When commercially packed fruits and vegetables continued to cause botulism, industry leaders voluntarily backed a cannery inspection act to legally require all California canners to possess appropriate equipment and follow scientifically validated sterilization procedures. After the California legislature approved the act in 1925, canneries were inspected, regulations were enforced, and no further outbreaks occurred.This botulism epidemic is an example of a disease outbreak that was controlled when business interests became aligned with public health goals. The press's portrayal of afflicted persons as innocent victims and worthy citizens galvanized businessmen to implement safeguards to protect consumers from botulism intoxication. To preserve their customer base and salvage their corporations, leaders of the canning industry acknowledged the public health threat of their unregulated procedures and acted on the recommendations of scientists.

Malignant Spindle Cell Tumor Breast—a Diagnostic Dilemma
Abstract
Primary malignant spindle cell tumors are rare constituting 1.0% of breast malignancies. Spindle cell lesions occurring in soft tissues can occur in breast with overlapping morphologies. It can present as benign lesion and have inconclusive cytological findings, so easily missed if not properly dealt with. Stromal sarcoma should be diagnosed only after thorough sectioning and negative staining for p63, broad spectrum, and high molecular weight keratin. We present a case of right breast lump. Cytological features revealed fibro histiocytic lesion. There were no areas of necrosis, hemorrhage, or calcification. Histopathologically, it showed partially encapsulated tumor with cells arranged in sheets, composed of oval to epithelioid cells with spindling at places with moderate pleomorphism (mitotic activity 6–7/10 hpf). Differential diagnosis of primary stromal sarcoma, metaplastic sarcoma, and phyllodes was made. Immunohistochemistry revealed vimentin positivity with focal positivity of S-100. Desmin, cytokeratin and smooth muscle actin, p63, ER, PR, and Her2-neu were negative. A final diagnosis of primary breast sarcoma of neural origin was established with the help of histopathology and immunohistochemistry. To conclude, it is of utmost importance to identify primary stromal sarcomas as they are known to spread very rapidly and have a poor prognosis.

Imaging appearance of well-differentiated liposarcomas with myxoid stroma
Abstract
Objective
Describe the imaging appearance of well-differentiated liposarcoma with myxoid stroma (WDLMS) and correlate with histopathology.
Materials and methods
A keyword search of the institution medical records was performed from 1 January 2000 to 30 June 2017. The histopathology slides of cases identified in this fashion were then reviewed by a pathologist. Additional cases were prospectively collected from extramural referrals and tumor boards. Diagnostic imaging studies of pathologically proven cases of WDLMS were then reviewed in consensus and correlated with pathology.
Results
Ten cases of pathologically proven WDLMS were identified (7 men, 3 women, ages 26–81). Tumor location included the retroperitoneum (n = 5), thigh (n = 4), and the shin (n = 1). Nine patients had macroscopic fat on imaging. The nonlipomatous components had a variable appearance, including septal, nodular, and lacelike patterns. Two cases included two distinct areas that were predominantly myxoid or lipomatous ("bi-morphic"). One tumor had no macroscopic fat on imaging. On CT, the nonlipomatous nodular components were hypodense/had hypodense areas. On MRI, the nodular components had intermediate/bright T2W signal. Interval nonlipomatous nodular growth was identified in 3 cases.
Conclusion
WDLMS may present on imaging as a mass with variable morphology and amounts of nonlipomatous components. Histopathological diagnosis of WDLMS is challenging and imaging correlation may be helpful, as this tumor may have ≥50% fatty volume, may have a myxoid nodular component or bi-morphic appearance, or may be located in the retroperitoneum, features that are unusual for myxoid liposarcoma. WDLMS with a nodular component cannot be distinguished from dedifferentiated liposarcoma based on imaging alone.

CT-guided biopsy in suspected spondylodiscitis: microbiological yield, impact on antimicrobial treatment, and relationship with outcome
Abstract
Purpose
To investigate the clinical impact of CT-guided biopsy, as performed in routine clinical practice, in patients with suspected spondylodiscitis on MRI in terms of culture yield, impact on antimicrobial treatment, and outcome.
Methods
This study included 64 patients with MRI findings compatible with spondylodiscitis who underwent CT-guided biopsy.
Results
Initial CT-guided biopsies were culture-positive in 20/64 (31.3%, 95% confidence interval [CI] 21.2–43.3%). Repeat CT-guided biopsies (after initial negative biopsy) were culture-positive in an additional 5/15 (33.3%, 95% CI 15.2–58.3%). Serum leukocytes, C-reactive protein, pre-biopsy use of antibiotics, neurological symptoms, MRI findings, vertebral height loss, and hyperkyphosis were not significantly different between culture-positive and culture-negative cases (P = 0.214–1.000); 75% (15/20) of initial CT-guided biopsies that were culture-positive provided additional information to clinicians for guiding antibiotic treatment. Sixty-two of 64 patients (96.9%, 95% CI 89.3–99.1%) would have been adequately treated if a strategy was followed that would subject all patients without clinical findings suspicious for "atypical" microorganisms and negative blood cultures to empirical antibiotics (i.e., clindamycin for coverage of Gram-positive bacteria) without using biopsy results to determine the optimal antibiotic regimen. Outcome within 6 months (development of neurologic or orthopedic complications, surgery, and death) was not significantly different (P = 0.751) between culture-positive and culture-negative patients.
Conclusions
Although CT-guided biopsies are culture-positive in a minority of cases, the majority of positive cultures are useful to tailor antibiotic treatment. Empirical treatment with clindamycin may cover almost all micro-organisms in positive biopsy specimens, provided patients are not immunocompromised. Outcome appears similar between culture-positive and culture-negative patients.
