Amyloid-β pathology enhances pathological fibrillary tau seeding induced by Alzheimer PHF in vivo

Abstract

Neuropathological analysis in Alzheimer's disease (AD) and experimental evidence in transgenic models overexpressing frontotemporal dementia with Parkinsonism linked to chromosome 17 (FTDP-17) mutant tau suggest that amyloid-β pathology enhances the development of tau pathology. In this work, we analyzed this interaction independently of the overexpression of an FTDP-17 mutant tau, by analyzing tau pathology in wild-type (WT), 5xFAD, APP−/− and tau−/− mice after stereotaxic injection in the somatosensory cortex of short-length native human AD-PHF. Gallyas and phosphotau-positive tau inclusions developed in WT, 5xFAD, and APP−/− but not in tau−/− mice. Ultrastructural analysis demonstrated their intracellular localization and that they were composed of straight filaments. These seeded tau inclusions were composed only of endogenous murine tau exhibiting a tau antigenic profile similar to tau aggregates in AD. Insoluble tau level was higher and ipsilateral anteroposterior and contralateral cortical spreading of tau inclusions was more important in AD-PHF-injected 5xFAD mice than in WT mice. The formation of large plaque-associated dystrophic neurites positive for oligomeric and phosphotau was observed in 5xFAD mice injected with AD-PHF but never in control-injected or in non-injected 5xFAD mice. An increased level of the p25 activator of CDK5 kinase was found in AD-PHF-injected 5xFAD mice. These data demonstrate in vivo that the presence of Aβ pathology enhances experimentally induced tau seeding of endogenous, wild-type tau expressed at physiological level, and demonstrate the fibrillar nature of heterotopically seeded endogenous tau. These observations further support the hypothesis that Aβ enhances tau pathology development in AD through increased pathological tau spreading.

The Bit (and Three Other Abstractions) Define the Borderline Between Hardware and Software

Abstract

Modern computing is generally taken to consist primarily of symbol manipulation. But symbols are abstract, and computers are physical. How can a physical device manipulate abstract symbols? Neither Church nor Turing considered this question. My answer is that the bit, as a hardware-implemented abstract data type, serves as a bridge between materiality and abstraction. Computing also relies on three other primitive—but more straightforward—abstractions: Sequentiality, State, and Transition. These physically-implemented abstractions define the borderline between hardware and software and between physicality and abstraction. At a deeper level, asking how a physical device can interact with abstract symbols is the wrong question. The relationship between symbols and physical devices begins with the realization that human beings already know what it means to manipulate symbols. We build and program computers to do what we understand to be symbol manipulation. To understand what that means, consider a light switch. A light switch doesn't turn a light on or off. Those are abstractions. Light switches don't operate with abstractions. We build light switches (and their associated circuitry), so that when flipped, the world is changed in such a way that we understand the light to be on or off. Similarly, we build computers to perform operations that we understand as manipulating symbols.

Ginsenoside Re Improves Isoproterenol-Induced Myocardial Fibrosis and Heart Failure in Rats

Objective. Panax ginseng is used widely for treatment of cardiovascular disorders in China. Ginsenoside Re is the main chemical component of P. ginseng. We aimed to investigate the protective effect of ginsenoside Re on isoproterenol-induced myocardial fibrosis and heart failure in rats. Methods. A model of myocardial fibrosis and heart failure was established by once-daily subcutaneous injection of isoproterenol (5 mg/kg/day) to rats for 7 days. Simultaneously, rats were orally administrated ginsenoside Re (5 or 20 mg/kg) or vehicle daily for 4 weeks. Results. Isoproterenol enhanced the heart weight, myocardial fibrosis, and hydroxyproline content in rat hearts. Ginsenoside Re inhibited (at least in part) the isoproterenol-induced increase in heart weight, myocardial fibrosis, and hydroxyproline content. Compared with the isoproterenol group, treatment with ginsenoside Re ameliorated changes in left ventricular systolic pressure, left ventricular end diastolic pressure, and the positive and negative maximal values of the first derivative of left ventricular pressure. Ginsenoside Re administration also resulted in decreased expression of transforming growth factor (TGF)-β1 in serum and decreased expression of Smad3 and collagen I in heart tissue. Conclusion. Ginsenoside Re can improve isoproterenol-induced myocardial fibrosis and heart failure by regulation of the TGF-β1/Smad3 pathway.

Effect of Employees’ Values on Employee Satisfaction in Japanese Retail and Service Industries

The Japanese workforce has decreased rapidly over the past few decades, and this is expected to continue. Retail and service industries are already experiencing human-resource shortages. In these industries, nonregular employees feature prominently. For most companies, recruitment is difficult, and employees change jobs often, making securing staff an important business issue. Nonregular and regular employees are treated differently; the problem is thus partly social in nature. However, some nonregular employees are content, although their work conditions are not good. Here, text mining was used to explore differences between the values of regular and nonregular employees in the retail and service industries.

Effect of Imatinib on Bone Marrow Morphology and Angiogenesis in Chronic Myeloid Leukemia

Background and Objectives. Chronic myeloid leukemia (CML) is characterized by hyperproliferation of myeloid precursors, increased fibrosis, and neoangiogenesis in the bone marrow. Imatinib inhibits BCR-ABL tyrosine kinase produced due to reciprocal translocation t(9;22) in neoplastic CML cells. It reduces hyperproliferation of myeloid precursors and has been found to affect bone marrow fibrosis and angiogenesis. This study was done to assess the effect of imatinib on bone marrow morphology and angiogenesis in CML. Methods. 31 newly diagnosed CML patients were evaluated before and after 3 months of imatinib therapy. A marrow morphological response (MMR) score was used to assess marrow cytological and histological features including grade of fibrosis. Mean microvessel density (MVD) was also assessed. Hematological parameters and BCR-ABL transcript levels were assessed in the peripheral blood. Results. 86.21% of patients showed decrease in marrow cellularity with normalization of M:E ratio. 72.42% of patients had decrease in grade of fibrosis and 17.24% showed no change while 10.34% of patients showed progression of fibrosis grade. Patients with MMR score ≥ 2 (n=4) and those with progression of fibrosis grade (n=3) showed suboptimal molecular response (BCR-ABL transcripts > 10%). Pretherapy mean MVD of patients (14.69 ± 5.28) was higher than that of controls (6.32 ± 1.64). A significant reduction of 66.51% was observed in posttherapy mean MVD (4.98 ± 2.77) of CML patients (p

Limitations and Misinterpretations of E-Values for Sensitivity Analyses of Observational Studies

The E-value was recently introduced on the basis of earlier work as "the minimum strength of association…that an unmeasured confounder would need to have with both the treatment and the outcome to fully explain away a specific treatment–outcome association, conditional on the measured covariates." E-values have been proposed for wide application in observational studies evaluating causality. However, they have limitations and are prone to misinterpretation. E-values have a monotonic, almost linear relationship with effect estimates and thus offer no additional information beyond what effect estimates can convey. Whereas effect estimates are based on real data, E-values may make unrealistic assumptions. No general rule can exist about what is a "small enough" E-value, and users of the biomedical literature are not familiar with how to interpret a range of E-values. Problems arise for any measure dependent on effect estimates and their CIs—for example, bias due to selective reporting and dependence on choice of exposure contrast and level of confidence. The automation of E-values may give an excuse not to think seriously about confounding. Moreover, biases other than confounding may still undermine results. Instead of misused or misinterpreted E-values, the authors recommend judicious use of existing methods for sensitivity analyses with careful assumptions; systematic assessments of whether and how known confounders have been handled, along with consideration of their prevalence and magnitude; thorough discussion of the potential for unknown confounders considering the study design and field of application; and explicit caution in making causal claims from observational studies.

A Pound of Prevention? Assessing the Value of New Cholesterol-Lowering Drugs

Proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors substantially reduce cholesterol levels, but the U.S. Food and Drug Administration–approved PCSK9 inhibitors, alirocumab and evolocumab, came to market priced at $14 000 per year—more than 100 times the cost of a generic statin. Kazi and colleagues performed a cost-effectiveness analysis of alirocumab in secondary prevention based on new trial results and updated pricing. The editorialist discusses the findings and what it takes for preventive therapies to be cost-effective.

Cost-Effectiveness of Alirocumab A Just-in-Time Analysis Based on the ODYSSEY Outcomes Trial

Background:
The ODYSSEY Outcomes (Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab) trial included participants with a recent acute coronary syndrome. Compared with participants receiving statins alone, those receiving a statin plus alirocumab had lower rates of a composite outcome including myocardial infarction (MI), stroke, and death.
Objective:
To determine the cost-effectiveness of alirocumab in these circumstances.
Design:
Decision analysis using the Cardiovascular Disease Policy Model.
Data Sources:
Data sources representative of the United States combined with data from the ODYSSEY Outcomes trial.
Target Population:
U.S. adults with a recent first MI and a baseline low-density lipoprotein cholesterol level of 1.81 mmol/L (70 mg/dL) or greater.
Time Horizon:
Lifetime.
Perspective:
U.S. health system.
Intervention:
Alirocumab or ezetimibe added to statin therapy.
Outcome Measures:
Incremental cost-effectiveness ratio in 2018 U.S. dollars per quality-adjusted life-year (QALY) gained.
Results of Base-Case Analysis:
Compared with a statin alone, the addition of ezetimibe cost $81 000 (95% uncertainty interval [UI], $51 000 to $215 000) per QALY. Compared with a statin alone, the addition of alirocumab cost $308 000 (UI, $197 000 to $678 000) per QALY. Compared with the combination of statin and ezetimibe, replacing ezetimibe with alirocumab cost $997 000 (UI, $254 000 to dominated) per QALY.
Results of Sensitivity Analysis:
The price of alirocumab would have to decrease from its original cost of $14 560 to $1974 annually to be cost-effective relative to ezetimibe.
Limitation:
Effectiveness estimates were based on a single randomized trial with a median follow-up of 2.8 years and should not be extrapolated to patients with stable coronary heart disease.
Conclusion:
The price of alirocumab would have to be reduced considerably to be cost-effective. Because substantial reductions already have occurred, we believe that timely, independent cost-effectiveness analyses can inform clinical and policy discussions of new drugs as they enter the market.

Correcting Misinterpretations of the E-Value

In their article, Ioannidis and colleagues raise several important issues concerning the potential misuse and misinterpretation of the E-value, a metric related to the robustness of associations to potential unmeasured or residual confounding. The editorialists discuss the usefulness of the E-value in practice in response to practical objections sometimes raised to other sensitivity analysis techniques that they are too complicated to describe in papers, are too difficult to present, take up too much space, and are difficult to understand.

Fracture Risk After Initiation of Use of Canagliflozin A Cohort Study

Background:
Sodium–glucose cotransporter-2 inhibitors promote glycosuria, resulting in possible effects on calcium, phosphate, and vitamin D homeostasis. Canagliflozin is associated with decreased bone mineral density and a potential increased risk for fracture.
Objective:
To estimate risk for nonvertebral fracture among new users of canagliflozin compared with a glucagon-like peptide-1 (GLP-1) agonist.
Design:
Population-based new-user cohort study.
Setting:
Two U.S. commercial health care databases providing data on more than 70 million patients from March 2013 to October 2015.
Patients:
Persons with type 2 diabetes who initiated use of canagliflozin were propensity score–matched in a 1:1 ratio to those initiating use of a GLP-1 agonist.
Measurements:
The primary outcome was a composite end point of humerus, forearm, pelvis, or hip fracture requiring intervention. Secondary outcomes included fractures at other sites. A fixed-effects meta-analysis that pooled results from the 2 databases provided an overall hazard ratio (HR).
Results:
79 964 patients initiating use of canagliflozin were identified and matched to 79 964 patients initiating use of a GLP-1 agonist. Mean age was 55 years, 48% were female, average baseline hemoglobin A1c level was 8.7%, and 27% were prescribed insulin. The rate of the primary outcome was similar for canagliflozin (2.2 events per 1000 person-years) and GLP-1 agonists (2.3 events per 1000 person-years), with an overall HR of 0.98 (95% CI, 0.75 to 1.26). Risk for pelvic, hip, humerus, radius, ulna, carpal, metacarpal, metatarsal, or ankle fracture was also similar for canagliflozin (14.5 events per 1000 person-years) and GLP-1 agonists (16.1 events per 1000 person-years) (overall HR, 0.92 [CI, 0.83 to 1.02]).
Limitation:
Unmeasured confounding, measurement error, and low fracture rate.
Conclusion:
In this study of middle-aged patients with type 2 diabetes and relatively low fracture risk, canagliflozin was not associated with increased risk for fracture compared with GLP-1 agonists.

Single-institution experience in 3D MRI-based brachytherapy for cervical cancer for 239 women: can dose overcome poor response?

Dose escalation has been suggested to improve outcomes in locally-advanced cervical cancer. We analyzed our institutional outcomes for women with locally advanced disease and evaluated the impact of dose on local control, progression, and survival. We found that, in line with GEC-ESTRO data, higher doses numerically but not statistically improve outcomes in women who have the poorest response (HRCTV >40cc) to chemoradiation.

Phase I trial of SBRT to the prostate fossa following prostatectomy

This Phase I trial evaluated the tolerability of moderate to extreme hypofractionation to the prostate fossa (PF), as measured by physician-scored toxicity and patient-reported outcomes. Given the similar EQD2 of all dose levels, we hypothesized that PF-SBRT would be well tolerated with toxicity comparable to standard fractionation. There was transient grade 2 rectal toxicity at all dose levels during and immediately following radiotherapy. We must await long-term follow-up to assess late toxicity.

The Burden of Candidate Pathogenic Variants for Kidney and Genitourinary Disorders Emerging From Exome Sequencing

Background:
Exome sequencing is increasingly being used for clinical diagnostics, with an impetus to expand reporting of incidental findings across a wide range of disorders. Analysis of population cohorts can help reduce risk for genetic variant misclassification and resultant unnecessary referrals to subspecialists.
Objective:
To examine the burden of candidate pathogenic variants for kidney and genitourinary disorders emerging from exome sequencing.
Design:
Secondary analysis of genetic data.
Setting:
A tertiary care academic medical center.
Patients:
A convenience sample of exome sequence data from 7974 self-declared healthy adults.
Measurements:
Assessment of the prevalence of candidate pathogenic variants in 625 genes associated with Mendelian kidney and genitourinary disorders.
Results:
Of all participants, 23.3% carried a candidate pathogenic variant, most of which were attributable to previously reported variants that had implausibly high allele frequencies. In particular, 25 genes (discovered before the creation of the Exome Aggregation Consortium, a genetic database comprising data from a large control population) accounted for 67.7% of persons with candidate pathogenic variants. After stringent filtering based on allele frequency, 1.4% of persons still had a candidate pathogenic variant, an excessive rate given the prevalence of monogenic kidney and genitourinary disorders. Manual annotation of a subset of variants showed that the majority would be classified as nonbenign under current guidelines for clinical sequence interpretation and could prompt subspecialty referrals if returned.
Limitation:
Limited access to health record data prevented comprehensive assessment of the phenotypic concordance with genetic diagnoses.
Conclusion:
Widespread reporting of incidental genetic findings related to kidney and genitourinary disorders will require stringent curation of clinical variant databases and detailed case-level review to avoid genetic misdiagnosis and unnecessary referrals. These findings motivate similar analyses for genes relevant to other medical subspecialties.

PROBAST: A Tool to Assess Risk of Bias and Applicability of Prediction Model Studies: Explanation and Elaboration

Prediction models in health care use predictors to estimate for an individual the probability that a condition or disease is already present (diagnostic model) or will occur in the future (prognostic model).Publications on prediction models have become more common in recent years, and competing prediction models frequently exist for the same outcome or target population. Health care providers, guideline developers, and policymakers are often unsure which model to use or recommend, and in which persons or settings. Hence, systematic reviews of these studies are increasingly demanded, required, and performed.A key part of a systematic review of prediction models is examination of risk of bias and applicability to the intended population and setting. To help reviewers with this process, the authors developed PROBAST (Prediction model Risk Of Bias ASsessment Tool) for studies developing, validating, or updating (for example, extending) prediction models, both diagnostic and prognostic.PROBAST was developed through a consensus process involving a group of experts in the field. It includes 20 signaling questions across 4 domains (participants, predictors, outcome, and analysis). This explanation and elaboration document describes the rationale for including each domain and signaling question and guides researchers, reviewers, readers, and guideline developers in how to use them to assess risk of bias and applicability concerns. All concepts are illustrated with published examples across different topics. The latest version of the PROBAST checklist, accompanying documents, and filled-in examples can be downloaded from www.probast.org.

Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a common systemic inflammatory autoimmune disease characterized by painful, swollen joints that can severely impair physical function and quality of life. The presenting symptoms of musculoskeletal pain, swelling, and stiffness are common in clinical practice, so familiarity with diagnosing and managing RA is crucial. Patients with RA are at greater risk for serious infection, respiratory disease, osteoporosis, cardiovascular disease, cancer, and mortality than the general population. In recent years, early diagnosis, aggressive treatment, and expanded therapeutic options of disease-modifying antirheumatic drugs have markedly improved both the management and long-term prognosis of RA.

PROBAST: A Tool to Assess the Risk of Bias and Applicability of Prediction Model Studies

Clinical prediction models combine multiple predictors to estimate risk for the presence of a particular condition (diagnostic models) or the occurrence of a certain event in the future (prognostic models).PROBAST (Prediction model Risk Of Bias ASsessment Tool), a tool for assessing the risk of bias (ROB) and applicability of diagnostic and prognostic prediction model studies, was developed by a steering group that considered existing ROB tools and reporting guidelines. The tool was informed by a Delphi procedure involving 38 experts and was refined through piloting.PROBAST is organized into the following 4 domains: participants, predictors, outcome, and analysis. These domains contain a total of 20 signaling questions to facilitate structured judgment of ROB, which was defined to occur when shortcomings in study design, conduct, or analysis lead to systematically distorted estimates of model predictive performance. PROBAST enables a focused and transparent approach to assessing the ROB and applicability of studies that develop, validate, or update prediction models for individualized predictions.Although PROBAST was designed for systematic reviews, it can be used more generally in critical appraisal of prediction model studies. Potential users include organizations supporting decision making, researchers and clinicians who are interested in evidence-based medicine or involved in guideline development, journal editors, and manuscript reviewers.

Finding the Balance Between Benefits and Harms When Using Statins for Primary Prevention of Cardiovascular Disease A Modeling Study

Background:
Many guidelines use expected risk for cardiovascular disease (CVD) during the next 10 years as a basis for recommendations on use of statins for primary prevention of CVD. However, how harms were considered and weighed against benefits is often unclear.
Objective:
To identify the expected risk above which statins provide net benefit.
Design:
Quantitative benefit–harm balance modeling study.
Data Sources:
Network meta-analysis of primary prevention trials, a preference survey, and selected observational studies.
Target Population:
Persons aged 40 to 75 years with no history of CVD.
Time Horizon:
10 years.
Perspective:
Clinicians and guideline developers.
Intervention:
Low- or moderate-dose statin versus no statin.
Outcome Measures:
The 10-year risk for CVD at which statins provide at least a 60% probability of net benefit, with baseline risk, frequencies of and preferences for statin benefits and harms, and competing risk for non-CVD death taken into account.
Results of Base-Case Analysis:
Younger men had net benefit at a lower 10-year risk for CVD than older men (14% for ages 40 to 44 years vs. 21% for ages 70 to 75 years). In women, the risk required for net benefit was higher (17% for ages 40 to 44 years vs. 22% for ages 70 to 75 years). Atorvastatin and rosuvastatin provided net benefit at lower 10-year risks than simvastatin and pravastatin.
Results of Sensitivity Analysis:
Most alternative assumptions led to similar findings.
Limitation:
Age-specific data for some harms were not available.
Conclusion:
Statins provide net benefits at higher 10-year risks for CVD than are reflected in most current guidelines. In addition, the level of risk at which net benefit occurs varies considerably by age, sex, and statin type.

Trends in Drug Use–Associated Infective Endocarditis and Heart Valve Surgery, 2007 to 2017 A Study of Statewide Discharge Data

Background:
Drug use–associated infective endocarditis (DUA-IE) is increasing as a result of the opioid epidemic. Infective endocarditis may require valve surgery, but surgical treatment of DUA-IE has invoked controversy, and the extent of its use is unknown.
Objective:
To examine hospitalization trends for DUA-IE, the proportion of hospitalizations with surgery, patient characteristics, length of stay, and charges.
Design:
10-year analysis of a statewide hospital discharge database.
Setting:
North Carolina hospitals, 2007 to 2017.
Patients:
All patients aged 18 years or older hospitalized for IE.
Measurements:
Annual trends in all IE admissions and in IE hospitalizations with valve surgery, stratified by patients' drug use status. Characteristics of DUA-IE surgical hospitalizations, including patient demographic characteristics, length of stay, disposition, and charges.
Results:
Of 22 825 IE hospitalizations, 2602 (11%) were for DUA-IE. Valve surgery was performed in 1655 IE hospitalizations (7%), including 285 (17%) for DUA-IE. Annual DUA-IE hospitalizations increased from 0.92 to 10.95 and DUA-IE hospitalizations with surgery from 0.10 to 1.38 per 100 000 persons. In the final year, 42% of IE valve surgeries were performed in patients with DUA-IE. Compared with other surgical patients with IE, those with DUA-IE were younger (median age, 33 vs. 56 years), were more commonly female (47% vs. 33%) and white (89% vs. 63%), and were primarily insured by Medicaid (38%) or uninsured (35%). Hospital stays for DUA-IE were longer (median, 27 vs. 17 days), with higher median charges ($250 994 vs. $198 764). Charges for 282 DUA-IE hospitalizations exceeded $78 million.
Limitation:
Reliance on administrative data and billing codes.
Conclusion:
DUA-IE hospitalizations and valve surgeries increased more than 12-fold, and nearly half of all IE valve surgeries were performed in patients with DUA-IE. The swell of patients with DUA-IE is reshaping the scope, type, and financing of health care resources needed to effectively treat IE.

Breast Cancer Risk After Recent Childbirth A Pooled Analysis of 15 Prospective Studies

Background:
Parity is widely recognized as protective for breast cancer, but breast cancer risk may be increased shortly after childbirth. Whether this risk varies with breastfeeding, family history of breast cancer, or specific tumor subtype has rarely been evaluated.
Objective:
To characterize breast cancer risk in relation to recent childbirth.
Design:
Pooled analysis of individual-level data from 15 prospective cohort studies.
Setting:
The international Premenopausal Breast Cancer Collaborative Group.
Participants:
Women younger than 55 years.
Measurements:
During 9.6 million person-years of follow-up, 18 826 incident cases of breast cancer were diagnosed. Hazard ratios (HRs) and 95% CIs for breast cancer were calculated using Cox proportional hazards regression.
Results:
Compared with nulliparous women, parous women had an HR for breast cancer that peaked about 5 years after birth (HR, 1.80 [95% CI, 1.63 to 1.99]) before decreasing to 0.77 (CI, 0.67 to 0.88) after 34 years. The association crossed over from positive to negative about 24 years after birth. The overall pattern was driven by estrogen receptor (ER)–positive breast cancer; no crossover was seen for ER-negative cancer. Increases in breast cancer risk after childbirth were pronounced when combined with a family history of breast cancer and were greater for women who were older at first birth or who had more births. Breastfeeding did not modify overall risk patterns.
Limitations:
Breast cancer diagnoses during pregnancy were not uniformly distinguishable from early postpartum diagnoses. Data on human epidermal growth factor receptor 2 (HER2) oncogene overexpression were limited.
Conclusion:
Compared with nulliparous women, parous women have an increased risk for breast cancer for more than 20 years after childbirth. Health care providers should consider recent childbirth a risk factor for breast cancer in young women.

Utility of CD123 immunohistochemistry in differentiating lupus erythematosus from cutaneous T‐cell lymphoma

Abstract

Aims

Histopathologic overlap between lupus erythematosus and certain types of cutaneous T‐cell lymphoma (CTCL) is well documented. CD123+ plasmacytoid dendritic cells (PDCs) are typically increased in lupus erythematosus, but have not been well studied in CTCL. We aimed to compare CD123 immunostaining and histopathologic features in these conditions.

Methods and Results

Skin biopsies of cutaneous lupus erythematosus (CLE, n=18), lupus erythematosus panniculitis (LEP, n=17), mycosis fungoides (MF, n=25) and subcutaneous panniculitis‐like T‐cell lymphoma (SPTCL, n=9) were retrospectively reviewed and immunostained with CD123. Percentage, distribution, and clustering of CD123+ cells were compared between CLE and MF, and between LEP and SPTCL, using Chi‐square and two‐tailed t tests. A higher percentage of CD123+ cells was observed in CLE than MF (p<0.01), more frequently comprising ≥20% of the entire infiltrate (p<0.01) and forming clusters (p<0.01). Similarly, LEP showed a higher percentage of CD123+ cells than SPTCL (p=0.01), more frequently comprising ≥20% of the infiltrate (p=0.04) and forming clusters (p=0.01). Basal vacuolar change or dyskeratosis was observed in all CLE cases and in 48% cases of MF cases (p=0.05). Plasma cells were readily identified in 76% cases of LEP but in none of the SPTCL cases (p=0.01). Adipocyte rimming by lymphocytes, hyaline fat necrosis, and fibrinoid/grungy necrosis did not significantly differ between LEP and SPTCL. Dermal mucin also failed to distinguish between groups.

Conclusions

CD123 immunostaining is helpful in differentiating CLE from MF and LEP from SPTCL, but should be interpreted in conjunction with clinicopathologic features and other ancillary studies to ensure accurate diagnosis.

Mesenchymal chondrosarcoma metastasising to the pancreas

The mesenchymal chondrosarcoma (MC) is a rare malignant tumour and accounts for less than 3% of primary chondrosarcomas. Mostly MC arises from the craniofacial bones, the ribs, the ilium, the femur and the vertebrae. A 54-year-old man was treated due to an icterus of unknown origin. The medical history of the patient consists of a multimodal treated MC of the thoracic vertebrae. A CT imaging identified a 2x4 cm sized mass of the pancreatic head. Suspecting a pancreatic head carcinoma surgical removal was performed. Histopathological a metastasis of MC was diagnosed. Our patient left the hospital after 17 days and died 23 month after surgery. Metastases of MC to the pancreas are rare. When detecting a mass of the pancreas in patients with a medical history of an MC, a metastasis of these tumour should be taken in consideration.

Unique complication of laparoscopic adjustable gastric band? A misplaced band encircling the abdominal aorta

In the recent past, laparoscopic adjustable gastric bands (LAGBs) have been used extensively in bariatric surgery. Despite questionable long-term efficacy, they are generally safe and reversible. We report a possibly unique presentation of a potential hazard of the insertion technique; a misplaced LAGB encircling the abdominal aorta, which was confirmed radiologically and on operative removal of the gastric band. This is a dramatic complication of LAGB, representing an important anatomical hazard for gastric band insertion.

Weekly paclitaxel, carboplatin, cetuximab, and cetuximab, docetaxel, cisplatin, and fluorouracil, followed by local therapy in previously untreated, locally advanced head and neck squamous cell carcinoma

Abstract
Background: The survival advantage of induction chemotherapy (IC) followed by locoregional treatment is controversial in locally advanced head and neck squamous cell carcinoma (LAHNSCC). We previously showed feasibility and safety of cetuximab-based IC (paclitaxel/carboplatin/cetuximab—PCC, and docetaxel/cisplatin/5-fluorouracil/cetuximab—C-TPF) followed by local therapy in LAHNSCC. The primary endpoint of this phase II clinical trial with randomization to PCC and C-TPF followed by combined local therapy in patients with LAHNSCC stratified by human papillomavirus (HPV) status and T-stage was two-year progression free survival (PFS) compared to historical control.Patients and methods: Eligible patients were ≥18 years with squamous cell carcinoma of the oropharynx, oral cavity, nasopharynx, hypopharynx or larynx with measurable stage IV (T0-4N2b-2c/3M0) and known HPV by p16 status. Stratification was by HPV and T-stage into one of two risk groups: (1) low-risk: HPV-positive and T0-3 or HPV-negative and T0-2; (2) intermediate/high-risk: HPV-positive and T4 or HPV-negative and T3-4. Patient reported outcomes were performed.Results: 136 patients were randomized in the study, 68 to each arm. With a median follow up of 3.2 years, the two-year PFS in the PCC arm was 89% in the overall, 96% in the low-risk and 67% in the intermediate/high-risk groups; in the C-TPF arm two-year PFS was 88% in the overall, 88% in the low-risk and 89% in the intermediate/high-risk groups.Conclusion: The observed two-year PFS of PCC in the low-risk group and of C-TPF in the intermediate/high-risk group showed a 20% improvement compared to the historical control derived from RTOG-0129, therefore reaching the primary endpoint of the trial.

HER2 exon 20 insertions in Non–Small Cell Lung Cancer are Sensitive to the Irreversible Pan-HER Receptor Tyrosine Kinase Inhibitor Pyrotinib

Abstract
Background
Effective targeted therapy for NSCLC patients with HER2 mutations remains an unmet need. This study investigated the anti-tumor effect of an irreversible pan-HER receptor tyrosine kinase inhibitor, pyrotinib.
Patients and methods
Using patient-derived organoids and xenografts established from a HER2-A775_G776YVMA-inserted advanced lung adenocarcinoma patient sample, we investigated the anti-tumor activity of pyrotinib. Preliminary safety and efficacy of pyrotinib in 15 HER2-mutant NSCLC patients in a phase 2 clinical trial are also presented.
Results
Pyrotinib showed significant growth inhibition of organoids relative to afatinib in vitro (P=0.0038). In the PDX model, pyrotinib showed a superior anti-tumor effect than afatinib(P=0.0471) and T-DM1(P=0.0138). Mice treated with pyrotinib displayed significant tumor burden reduction (mean tumor volume, -52.2%). In contrast, afatinib (25.4%) and T-DM1 (10.9%) showed no obvious reduction. Moreover, pyrotinib showed a robust ability to inhibit pHER2, pERK and pAkt. In the phase 2 cohort of 15 patients with HER2-mutant NSCLC, pyrotinib 400mg resulted in an ORR of 53.3% and a median PFS of 6.4 months.
Conclusion
Pyrotinib showed activity against NSCLC with HER2 exon 20 mutations in both patient-derived organoids and a PDX model. In the clinical trial, pyrotinib showed promising efficacy.

Novel Approaches to the Control of Oral Microbial Biofilms

Effective management of biofilm-related oral infectious diseases is a global challenge. Oral biofilm presents increased resistance to antimicrobial agents and elevated virulence compared with planktonic bacteria. Antimicrobial agents, such as chlorhexidine, have proven effective in the disruption/inhibition of oral biofilm. However, the challenge of precisely and continuously eliminating the specific pathogens without disturbing the microbial ecology still exists, which is a major factor in determining the virulence of a multispecies microbial consortium and the consequent development of oral infectious diseases. Therefore, several novel approaches are being developed to inhibit biofilm virulence without necessarily inducing microbial dysbiosis of the oral cavity. Nanoparticles, such as pH-responsive enzyme-mimic nanoparticles, have been developed to specifically target the acidic niches within the oral biofilm where tooth demineralization readily occurs, in effect controlling dental caries. Quaternary ammonium salts (QAS) such as dimethylaminododecyl methacrylate (DMADDM), when incorporated into dental adhesives or resin composite, have also shown excellent and durable antimicrobial activity and thus could effectively inhibit the occurrence of secondary caries. In addition, custom-designed small molecules, natural products and their derivatives, as well as basic amino acids such as arginine, have demonstrated ecological effects by modulating the virulence of the oral biofilm without universally killing the commensal bacteria, indicating a promising approach to the management of oral infectious diseases such as dental caries and periodontal diseases. This article aims to introduce these novel approaches that have shown potential in the control of oral biofilm. These methods may be utilized in the near future to effectively promote the clinical management of oral infectious diseases and thus benefit oral health.

The Efficacy and Safety of Norepinephrine and Its Feasibility as a Replacement for Phenylephrine to Manage Maternal Hypotension during Elective Cesarean Delivery under Spinal Anesthesia

Maternal hypotension commonly occurs during spinal anesthesia for cesarean delivery, with a decrease of systemic vascular resistance recognized as a significant contributor. Accordingly, counteracting this effect with a vasopressor that constricts arterial vessels is appropriate, and the pure α-adrenergic receptor agonist phenylephrine is the current gold standard for treatment. However, phenylephrine is associated with dose-dependent reflex bradycardia and decreased cardiac output, which can endanger the mother and fetus in certain circumstances. In recent years, the older, traditional vasopressor norepinephrine has attracted increasing attention owing to its mild β-adrenergic effects in addition to its α-adrenergic effects. We search available literature for papers directly related to norepinephrine application in spinal anesthesia for elective cesarean delivery. Nine reports were found for norepinephrine use either alone or compared to phenylephrine. Results show that norepinephrine efficacy in rescuing maternal hypotension is similar to that of phenylephrine without obvious maternal or neonatal adverse outcomes, and with a lower incidence of bradycardia and greater cardiac output. In addition, either computer-controlled closed loop feedback infusion or manually-controlled variable-rate infusion of norepinephrine provides more precise blood pressure management than equipotent phenylephrine infusion or norepinephrine bolus. Thus, based on the limited available literature, norepinephrine appears to be a promising alternative to phenylephrine; however, before routine application begins, more favorable high-quality studies are warranted.

Objective: In this study, we have described the technique to overcome difficulty faced during trans-foraminal endoscopic discectomy for the treatment of lumbar radiculopathy in patients who have herniated discs at the upper lumbar level & thoracolumbar junction. Method: After institutional review board approval, A retrospective analysis of 27 patients operated between March 2013- September 2017, by a single specialist for disc herniation at upper lumbar levels D12-L1, L1-2, L2-3 with or without high canal compromise by outside in technique (using rigid endoscope, sequential reamers) along with detailed description of our technique is the focus of this study. Results: Out of 27 patients there were 11 cases for L1-2 & 16 cases of L2-3 disc herniation respectively. There were 21 cases of broad-based, high canal compromised disc herniation with significant neurological deficit & only 6 cases were of focal herniation type. The average preoperative VAS score of 8.5 (range 6-10) reduced to 4 (range 2-7) immediate postoperatively & it further reduced to 2 (range 0-4) at one month follow up. The average preoperative ODI score of 65 (range 28- 88) reduced to 27 (range 12-40) immediate postoperatively & it further reduced to 10 (range 3- 18) at one month follow up. Post-operative MRI showed that the ruptured disc had been successfully removed. Conclusion: An anatomically modified surgical technique promote a more successful outcome after percutaneous endoscopic discectomy for upper lumbar disc herniation. Foraminotomy is recommended for all intra-canalicular herniation. Transforaminal endoscopic discectomy and foraminotomy can be used as a safe yet minimally invasive technique for the treatment of lumbar radiculopathy in the setting of an upper lumbar disc herniation.

Neuropathic pain (NeP) constitutes a major pain-related disorder, which is often underdiagnosed and undertreated. Adverse physical, psychological, and economic consequences associated with NeP lead to poor quality of life. Burden of NeP in developing countries like India is colossal. Various international guidelines provide effective approaches to diagnose and manage NeP. However, differences in the genetic makeup of Indian population can result in subtle differences in clinical response, considering their low body weight, drug metabolism ability, and pain perception. Similarly, treatment-related adverse effects may also vary. Practice of Indian physicians may also differ for choice of drugs based on their availability and affordability. In the absence of country-specific guidelines, this document could serve as a guiding tool for health-care providers, ensuring uniformity in the treatment of NeP. Thus, applicability of all recommendations from any of these guidelines in Indian setting demands careful evaluation. Clinical experience of Indian physicians suggests that there are lot many challenges (e.g., busy outpatient departments, nonavailability of screening questionnaires in regional languages, and availability and affordability of medications) faced by them when managing NeP. In addition, in India, there are no country-specific guidelines that would help them to address these challenges. The objective for this consensus was to develop an expert opinion guideline to harmonize the management of NeP in India. The expert panel consisted of experts from various specialties such as pain medicine, anesthesiology, diabetology, neurology, and orthopedics. The panel critically reviewed the existing literature evidence and guideline recommendations to provide India-specific consensus on the management of NeP. The final consensus document was reviewed and approved by all the experts. This expert opinion consensus will help health-care professionals as a guiding tool for effective management of NeP in India. Use of Douleur Neuropathique 4 (DN4) questionnaire for NeP screening should be routine in day-to-day clinical practice. For effective utilization of DN4 questionnaire, it should be converted to regional language. If DN4 questionnaire screening fails to identify NeP, it should not be disregarded and should not replace the sound clinical judgment from the treating physician. Diagnostic tests may be considered as a supplement to clinical judgment. Cost-effective treatment should be the initial choice. Dosing should be individualized based on efficacy and tolerability. Tricyclic antidepressants (TCAs), gabapentinoids, and serotonin-norepinephrine reuptake inhibitors (SNRIs) can be considered among initial choices. Tramadol can be considered as a second-line add-on treatment for NeP if there is partial response to the first-line agent either alone or in combination. Fixed-dose combination (FDC) of gabapentinoids such as pregabalin (75 mg) with TCA such as nortriptyline (10 mg) is synergistic and improves treatment adherence. Among other treatments, Vitamin B12 (methylcobalamin) can be used either alone or in combination for the management of NeP. Use of Vitamin D and steroids should be limited to specific NeP in individual cases. Referral to pain specialists can be considered if two drugs fail to provide relief in NeP.

Is tactile acuity altered in individuals with acute mechanical neck pain?p. 145
Shobhalakshmi S Holla, Turiya Vats, Pratima Nagpal
DOI:10.4103/ijpn.ijpn_20_18  
Background: Tactile acuity measured by point discrimination (TPD) refers to the precision by which we can sense touch.An increase in TPD threshold (loss of tactile acuity) is considered suggestive of disruptions to S1 cortical maps of that specific body part. In some chronically painful conditions, reduced tactile acuity is a manifestation of Central sensitization (CS).The other symptoms include hyperalgesia and allodynia due to repeated activation of spinal nociceptors. A recent study has shown that tactile acuity is affected in individuals with chronic neck pain. While there seems to be adequate evidence stating that tactile acuity is reduced in individuals with chronic pain, CS may not be limited to chronic pain states. There is a paucity of literature with respect to the tactile acuity of a person with acute neck pain. A measurement of tactile acuity of the affected body area in acute pain, may suggest the extent of the altered threshold of sensory discriminative aspect of pain experience. Objectives: To compare the two-point discrimination over C7 spinous process between the symptomatic individuals with mechanical neck pain and age matched healthy controls. Methods: 30 individuals with mechanical neck pain & 30 age matched normals were assessed for two point discrimination using mechanical calipers, The two sharp points of the caliper were vertically placed against the skin surface over C7 spinous process, commencing with 5mm, which was stretched out till the subject appreciated the two points. Values were noted down in millimeters. Results: An independent t – test showed a significant difference in the two point discrimination between the 2 groups (P < 0.000). Conclusion: It can be concluded that individuals with acute mechanical neck pain demonstrated a change in tactile acuity.

DOI:10.4103/ijpn.ijpn_21_18  
Context: Lower extremity peripheral nerve blocks are increasingly being recommended for pain control in patients with fracture femur as it reduces pain and shortens the duration of hospital stay. Aims: To compare analgesic efficacy of ultrasound guided femoral nerve block (FNB) and fascia iliaca compartment block (FICB) in patients with fracture femur for reducing pain associated with positioning for subarachnoid block. Settings and Design: It was a prospective, randomized, double blind study. Methods and Material: Group A (n = 25) received ultrasound guided FNB and Group B (n = 25) received ultrasound guided FICB using 0.5% ropivacaine. Primary objective was to observe reduction in pain associated with positioning (sitting) for subarachnoid block. Statistical Analysis used: For data analysis t test, Mann Whitney test and Chi-square test were applied. Results: Visual analog scale (VAS) score for pain before giving peripheral nerve block between Group A (7.60 ± 0.57) and Group B (7.44 ± 0.50) was comparable (P = 0.302). VAS score for pain in sitting position before giving subarachnoid block was lesser in Group A (1.88 ± 0.83) than in Group B (2.40 ± 0.57) (P = 0.013). Mean reduction in VAS score for pain was more in Group A (5.72 ± 0.73) compared to Group B (5.04 ± 0.73) (P = 0.002). Conclusion: Ultrasound guided FNB is more efficacious in reducing pain associated with positioning (sitting) for subarachnoid block in patients undergoing surgery for fracture femur compared to ultrasound guided FICB.

DOI:10.4103/ijpn.ijpn_33_18  
Aims: 1. Study the change in pain and function in patient with lumbosacral disc disease on MRI using visual analogue scale (VAS) and the revised Oswestry disability index (ODI) for back pain after administration of fluoroscopically guided transforaminal epidural injection. 2. Correlate the response of the patient with the spread of contrast in epidural space. Method: 100 patients with history of low back ache and imaging findings of disc herniation were enrolled based on inclusion criteria. Patients scored their pain on the VAS and functional disability on revised ODI. The patient was evaluated for distribution of pain and was administered a combination of anaesthetic and steroid after confirming the position of the tip of needle using iodinated contrast. Follow up for response to pain and improvement in disability in immediate post procedure done at 3 and 6 months. Result: 102 injections were administered for 100 patients which comprised of n=69 {67.6%} male and 33{32.4%} female and age distribution was 21-79 years. The distribution of indication was disc bulge n=29 (28.4%), extrusion n=12 (11.8%), post operative n=19 (18.6%), protrusion n=42 (41.2%). No significant difference between the VAS scores (p=0.20) of the individual indication pre procedure. After 3 & 6 months there was statistically significant difference between the mean rank value of population indicating maximum benefit for disc bulge population and least for post operative population at three months follow up. Conclusion: There is statistically proven good results in all cases for 6 months, after which repeat injections may be tried.

Perception, knowledge, and attitudes of first-year postgraduates toward postoperative pain management: A questionnaire-based studyp. 163
Pritam B Adsule, Pradnya M Bhalerao, Prakash R Dhumal
DOI:10.4103/ijpn.ijpn_31_18  
Context: Inadequately controlled postoperative pain has undesirable physiological and psychological consequences. It increases postoperative morbidity, delays recovery, and hence causes a delayed return to normal daily living. Furthermore, the lack of adequate postoperative pain treatment may lead to persistent pain after surgery, which is often overlooked. Overall, inadequate pain management increases the use of health care resources and health care costs. Aim: To evaluate the knowledge and attitudes of first-year postgraduate students toward postoperative pain. Study Design: This questionnaire-based cross-sectional study was conducted on 42 first-year postgraduate students. Materials and Methods: A 20-point questionnaire was prepared based on the various aspects of postoperative pain services. The students were asked to provide their answers on a five-point Likert scale ranging from "strongly disagree" to "strongly agree." The responses were kept anonymous, and the results were expressed in terms of percentage. Results:Almost 70% of students had a good knowledge of opioids, 52% strongly felt the need for a structured pain curriculum, 76% were well aware of nonpharmacological methods of pain relief, 48% agreed on the need for a pain physician, and 52% were aware of the advantage of postoperative analgesia. Conclusion: This pilot study helped us to evaluate the current understanding of our first-year postgraduate students and further created awareness on the importance of pain relief postoperatively.

Translation and validation of Marathi version of Fear-Avoidance and Belief Questionnaire in patients with chronic low back painp. 173
Vrushali P Panhale, Reshma S Gurav, Kartiki Suradkar
DOI:10.4103/ijpn.ijpn_41_18  
Background: Fear-Avoidance Beliefs Questionnaire (FABQ) is widely used to assess the fear-avoidance beliefs in patients with low back pain (LBP). However, English serves as a barrier to the population of the state where Marathi is the prime language. Hence, the FABQ needs to be translated into Marathi for the ease of its use. Materials and Methods: FABQ was successfully translated in Marathi using forward-backward translation using recommended guidelines. The final version of FABQ-Marathi version (FABQ-M) was used on 100 patients with chronic nonspecific LBP to assess its reliability and validity. Reliability was assessed by measuring the internal consistency of FABQ-M and its subscales and by checking the test-retest reliability on day 1 and day 2. For the determination of construct validity, convergent and divergent validity was assessed. The floor and ceiling effects were studied. Results: Reliability-internal consistency-Cronbach's alpha for FABQ-M was 0.860 and test–retest: correlation between FABQ-M on day 1 and day 2 were highly significant. The intraclass coefficient was 0.976. There was a high internal consistency between the FABQ-M and its subscales. On assessing convergent validity, there was moderate correlation found between FABQ-M and TSK (r = 0.52, P = 0.00). Divergent validity showed moderate correlation between FABQ-M and NRS (r = 0.48, P = 0.00) and between FABQ-M and RMDQ (r = 0.59, P = 0.00). Conclusion: The translated FABQ-M proved to be acceptable. The results suggest it is a validated, an easy to comprehend, reliable, and valid instrument for the measurement of the fear and avoidance beliefs caused by back disorders in the Marathi-speaking population.

Quadratus lumborum: One of the many significant causes of low back painp. 184
Asha Satish Barge, Satish Mahadeo Barge
DOI:10.4103/ijpn.ijpn_53_18  
Quadratus lumborum is one of the common sources of pain and that can be missed or ignored easily. Quadratus lumborum pain syndrome is a myofascial pain syndrome. The pain is due to spasm and stiffness of the muscle. Many a times, weak back muscles are compensated by quadratus lumborum leading to painful spasm. It is diffi cult to differentiate between quadratus lumborum and iliopsoas pain syndrome. Diagnostic quadratus lumborum injection helps differentiate between these two. In this report, we reported a case of quadratus lumborum pain syndrome as a primary diagnosis and iliopsoas pain syndrome as a secondary diagnosis. The diagnosis was confi rmed by fl uoroscopically guided quadratus lumborum injection.

A 50-year-old female presented with severe pain at the cholecystectomy scar site of 4 months' duration. She had an open cholecystectomy done followed by continuous pain from the time of discharge. She was diagnosed as a case of chronic postsurgical pain (CPSP) syndrome. We administered right-sided erector spinae (ES) block by ultrasound guidance depositing 15 ml of 0.25% bupivacaine and 40 mg of methylprednisolone at site of incision. The visual analog score showed significant improvement from 7/10 to 2/10 for the next 2 months of follow-up. We conclude that ultrasonography-guided ES block combined with intralesional steroid is a viable treatment option in cases of CPSP. This is possibly the first case report of postcholecystectomy chronic pain managed with ES block.

Cervical epidural steroid injection is an intervention done for cervical prolapsed intervertebral disc. Cervical epidural steroid injection is done if a patient has not responded to medications and physical therapy. We discuss a case report of the occurrence of Horner's syndrome in the patient with cervical radiculopathy undergoing cervical interlaminar epidural steroid injection which resolved spontaneously without residual side effects.
