Analgesic Effectiveness of Preoperative Ultrasound‐Guided Erector Spinae Plane Block versus Paravertebral Nerve Block for Breast Surgery: A Systematic Review and Meta Analysis of Four Randomized Controlled Trials

alexandrossfakianakis shared this article with you from Inoreader Analgesic Effectiveness of Preoperative Ultrasound‐Guided Erector Spinae Plane Block versus Paravertebral Nerve Block for Breast Surgery: A Systematic Review and Meta Analysis of Four Randomized Controlled Trials via Pain Practice Abstract Objective Our meta-analysis aimed to compare the analgesic effectiveness of ultrasound-guided preoperative erector spinae plane block (ESPB) versus paravertebral nerve block (PVB) in breast surgery. Methods PubMed, EMBASE and the Cochrane Library were searched for randomized controlled trials (RCTs) between January 1, 1980 and April 31, 2021 . The primary endpoints were perioperative pain score, analgesic consumption and assessment of block procedure. The secondary endpoints were intraoperative haemodynamic response, duration of surgery, postoperative antiemetic consumption and adverse effects. Results Four RCTs comprised of a total of 310 patients were included in our meta-analysis. No significant differences in the perioperative pain score and analgesic consumption were observed between ESPB and PVB in the operating room, post-anaesthesia care unit (PACU) and ward (at 1, 16, 12, and 24 hour, and the morning of postoperative day 1 (POD1) (all P > 0.05). Similarly, no significant differences in the duration of block, time to first analgesic, haemodynamic response, duration of surgery, postoperative antiemetic consumption and adverse effects were observed (all P > 0.05). However, our meta-analysis revealed that ultrasound-guided preoperative ESPB significantly reduced the duration of procedure time and frequency of guidance interventions, as well as increasing the block success rate among residents (all P < 0.05). Conclusions Both ultrasound-guided preoperative ESPB and PVB showed comparable analgesic effects in patients undergoing breast surgery. However, with a significantly shorter procedure time and higher block success rate, our findings suggest that ESPB may be a simple alternative to PVB in breast surgery. View on Web

The association among insomnia symptom severity, comorbid symptoms, and suicidal ideation in two veteran cohorts meeting diagnostic criteria for insomnia disorder

alexandrossfakianakis shared this article with you from Inoreader The association among insomnia symptom severity, comorbid symptoms, and suicidal ideation in two veteran cohorts meeting diagnostic criteria for insomnia disorder via Journal of Clinical Psychology Abstract Objective Examine the association between insomnia symptom severity and suicidal ideation (SI), after adjusting for clinical comorbidity in veterans meeting diagnostic criteria for insomnia disorder. Methods Secondary data analyses of psychometrically validated baseline assessments of depression, posttraumatic stress disorder (PTSD), and anxiety symptoms from two online insomnia intervention randomized clinical trials (n = 232; n = 80) were conducted. Multiple linear regression was used to determine the association between insomnia symptom severity and SI, after controlling for clinical comorbidity and demographics. Results Insomnia symptom severity was significantly correlated with comorbid depression, PTSD, and anxiety symptoms in both cohorts and significantly correlated with SI in one. After controlling for demographics and clinical comorbidity, insomnia symptom severity was not significantly associated with SI in linear regression models. Conclusion Findings extend insomnia-suicide research by providing evidence that insomnia symptom severity may not confer a unique risk for SI above comorbid mental health symptoms in veterans meeting diagnostic criteria for insomnia disorder.

Enhanced recombination among omicron subvariants of SARS‐CoV‐2 contributes to viral immune escape

alexandrossfakianakis shared this article with you from Inoreader Enhanced recombination among omicron subvariants of SARS‐CoV‐2 contributes to viral immune escape via Journal of Medical Virology Abstract Genetic recombination is an important driver of SARS-CoV-2 evolution, which requires the co-infection of a single host cell with different SARS-CoV-2 strains. To understand the emergence and prevalence of recombinant SARS-CoV-2 lineages through time and space, we analyzed SARS-CoV-2 genome sequences collected from November 2019 to July 2022. We observed an extraordinary increase in the emergence of SARS-CoV-2 recombinant lineages during the Omicron wave, particularly in Northern America and Europe. This phenomenon was independent of the sequencing frequency or genetic diversity of circulating SARS-CoV-2 strains. The recombination breakpoints were more prevalent in the 3' UTR of the viral genome. Importantly, we noted the enrichment of certain amino acids in the spike protein of recombinant lineages, which have been reported to confer immune escape from neutralizing antibodies and increase ACE2 receptor binding in some cases. We also observed I42V amino acid change genetically fi xated in the NSP14 of the Omicron lineage, which needs further characterization for its potential role in enhanced recombination. Overall, we report the important and timely observation of accelerated recombination in the currently circulating SARS-CoV-2 Omicron variants and explore their potential contribution to viral fitness, particularly immune escape.

Use of gemcitabine, oxaliplatin, and anti‐CD20 therapy in children and adolescents with non‐Hodgkin lymphoma unfit for intensive therapy

alexandrossfakianakis shared this article with you from Inoreader Use of gemcitabine, oxaliplatin, and anti‐CD20 therapy in children and adolescents with non‐Hodgkin lymphoma unfit for intensive therapy via Pediatric Blood & Cancer Abstract Multiagent immunochemotherapy affords excellent outcomes in pediatric non-Hodgkin lymphoma (NHL); however, scarce data exist for patients unfit for intensive treatment. Rituximab, gemcitabine, and oxaliplatin (R-GemOx) is well tolerated and efficacious in elderly adults with NHL; however, its use has not been described in pediatrics. In this retrospective, single-center study, six children with mature B-cell NHL and significant comorbidities received anti-CD20 therapy with GemOx (rituximab or obinutuzumab or ofatumumab with gemcitabine and oxaliplatin [R/O-GemOx]). R/O-GemOx was well tolerated and resulted in complete response in two of three patients with newly diagnosed NHL and one of three patients with primary refractory NHL. R/O-GemOx is a viable treatment option for children with NHL who cannot tolerate intensive therapy. View on Web

Serial In‐Office Steroid Injections for Airway Stenosis: Long‐Term Benefit and Cost Analysis

alexandrossfakianakis shared this article with you from Inoreader Serial In‐Office Steroid Injections for Airway Stenosis: Long‐Term Benefit and Cost Analysis via The Laryngoscope Serial in office steroid injection help avoid operative intervention regardless of stenosis etiology. Follow up of at least 2 years suggest that serial in office steroid injection can avoid operative intervention long term. There is potential cost savings associated with serial steroid injection over traditional endoscopic dilation. Objectives To evaluate the long-term benefit of serial in-office steroid injections (SISI) in the treatment of subglottic and proximal tracheal stenosis (SG/PTS). Evaluate cost of SISI compared to endoscopic dilation (ED). Study Design Retrospective study and cost analysis. Methods All patients with SGS/PTS with at least two consecutive in-office steroid injections between 2013 and 2021 were evaluated. Patients with less than 2 years of follow-up data after the initial SISI series were excluded. Demographics, etiology of stenosis, total injections performed, time between steroid series, surgery-free interval (SFI) and adverse events were collected. For patients with known surgical history before SISI, pre-SISI SFI was compared. Institutional billing records and the national CMS average reimbursement were evaluated. Total charges for three treatment strategies (ED alone, ED with post-operative SISI and primary intervention with SISI) were also compared. Results Forty-nine patients were included; 29 (59%) idiopathic, 11 (22%) traumatic and 9 (18%) rheumatologic. Mean (SD) follow-up time after the first SISI was 3.41 years (1.5), range (2.08–7.25 years). 79% (39/49) did not require additional surgery during the entire follow-up period. The SFI improved from a mean 13.5 months (SD 12.6; range 2–42 months) pre-SISI to a mean (SD) of 42 months (SD 20.2; range 10–87 months) (p < 0.0001) after SISI. Annual average charges for ED alone in our cohort was $15,383.28, compared to $7,070.04 for SISI. Conclusions SISI are an effective treatment for patients with SG/PTS. In-office steroid injections could offer cost savings for the patient. Level of Evidence 4 Laryngoscope, 2023 View on Web

Radiological evolution of progestogen‐induced meningioma: A monocentric retrospective study

alexandrossfakianakis shared this article with you from Inoreader Radiological evolution of progestogen‐induced meningioma: A monocentric retrospective study via Fundamental & Clinical Pharmacology Abstract Context Cyproterone acetate (CPA) is known to induce meningioma, and recently, nomegestrol acetate (NMA) and chlormadinone acetate (CMA) were also involved. Progestagen-induced meningioma management starts with progestogen discontinuation and is either interventional (surgery and/or radiotherapy) or conservative (clinical and MRI radiological follow-up). We performed a retrospective volumetric radiological outcome study of progestogen-induced meningiomas diagnosed in our hospital. Method We analysed progestogen-related meningiomas diagnosed until 30 June 2021, with at least one diagnostic and one follow-up MRI results. Meningioma volumes were centrally retrospectively measured using a T1-weighted 3D millimeter sequence with gadolinium injection on a post-processing console. Results We analysed 98 meningiomas of 38 females and one transgender (male-to-female), of which 25 (64.1%) had taken CPA, 7 (17.9%) NMA, 3 (7.7%) CMA, and 4 (10.2%) several progestogens. Eleven patients (24 meningiomas) underwent interventional management, 7 patients had meningiomas followed by conservative or interventional management, and 21 patients (51 meningiomas) had only conservative management. Of these 21 patients, 17 had discontinued their progestogen less than 6 months before, of which 14 (82.3%) had decreased or stable meningioma(s) during a 24-month median follow-up [3 to 75] period. Overall four of the 39 patients experienced meningioma progression (three during conservative treatment and one after surgery), including two patients who had continued NMA or CMA treatment several years after diagnosis. Conclusion Our study confirms a generally favorable outcome of progestogen-related meningioma after conservative treatment, especially for CPA. It also underlines the need for progestogen discontinuation at meningioma diagnosis. View on Web
