Restorative Neurostimulation Therapy Compared to Optimal Medical Management: A Randomized Evaluation (RESTORE) for the Treatment of Chronic Mechanical Low Back Pain due to Multifidus Dysfunction.

Introduction: Many interventional strategies are commonly used to treat chronic low back pain (CLBP), though few are specifically intended to target the distinct underlying pathomechanisms causing low back pain. Restorative neurostimulation has been suggested as a specific treatment for mechanical CLBP resulting from multifidus dysfunction. In this randomized controlled trial, we report outcomes from a cohort of patients with CLBP associated with multifidus dysfunction treated with restorative neurostimulation compared to those randomized to a control group receiving optimal medical management (OMM) over 1 year.

Incidence, characteristics, and prognostic significance of early recurrences after different ablation approaches for persistent atrial fibrillation.

Background: Early recurrence of atrial tachyarrhythmia (ERAT) is common after catheter ablation of atrial fibrillation (AF). The specific clinical and arrhythmia characteristics of ERAT influencing late recurrence risk in persistent AF are unclear. In addition, the impact of different ablation strategies on the incidence and prognostic significance of ERAT remains unknown.

Association between modifiable and nonmodifiable risk factors with paralumbar muscle health in patients with lower back pain.

Background: Prior studies have linked sarcopenia and fat infiltration in paraspinal muscles with lumbar pain, spinal pathology, and adverse postoperative outcomes in lumbar spine surgery. A recent magnetic resonance imaging (MRI)-based method for assessing muscle health, incorporating parameters such as Goutallier Classification (GC) and the Paralumbar Muscle Cross-Sectional Area to Body Mass Index ratio (PL-CSA/BMI), has shown that higher muscle grades correlate with significant improvements in patient-reported outcomes. Despite these advancements, there is limited research on the associations between paralumbar muscle health and factors such as age, BMI, walking tolerability, and spondylolisthesis.

A diazirine's central carbon is sp-hybridized, facilitating conjugation to dye molecules.

Diazirines are versatile carbene precursors that are extensively used in biological target identification experiments. However, their photo-activation wavelength ( 365 nm) precludes their use in living organisms. Here we show that a reconceptualization of the diazirine hybridization state leads to conjugation of the diazirine motif to longer-wavelength chromophores.

Defining blood deserts and access to blood products for 660 million people: a geospatial analysis of eight states in Northern India.

Introduction: Blood transfusion is crucial, but low-income and middle-income countries like India face a severe shortage of banked blood. This study focuses on the Empowered Action Group (EAG) states in India, where healthcare is limited, and health outcomes are poor. Our objective was to assess the blood banking infrastructure and access to blood products in these states.

Time-related underemployment in Indian agro-based industry during Covid-19.

Background: COVID-19 has adversely affected the different aspects of work and society. Due to the decline in economic activity globally, employees were exposed to conditions in which they were forced to work for reduced working hours leading to an increase in time-related underemployment.

Objective: The goal of the present study was to determine the extent of time-related underemployment and the rate of unutilized labor resource in the Agro-based Industry.

A Cadaveric Comparison of Discectomy Performance During Transforaminal Lumbar Interbody Fusion Approach Using an Endoscopic Technique versus a Minimally Invasive Tubular Approach.

Study Design: Cadaveric study.

Objective: Compare discectomy performance between transforaminal lumbar interbody fusion (TLIF) done via an endoscopic versus a tubular technique.

Summary Of Background Data: Performance of an adequate discectomy is essential to lumbar fusion when performing a TLIF.

Impact of COVID-19 on pregnancy outcomes during delivery admissions: a nationwide analysis with clinical implications.

Background: The available literature indicates a link between SARS-CoV-2 infection during pregnancy and a heightened probability of experiencing negative outcomes for both the pregnant patient and the developing fetus. We compared clinical outcomes of pregnant patients with or without COVID-19 hospitalized during delivery.

Methods: Multivariate logistic regression analysis was used to compare outcomes and was adjusted for patient-related, hospital-related, and illness severity indicators.

Adjunctive Statistical Standardization of Adjuvant Estrogen Receptor and Progesterone Receptor in Canadian Cancer Trials Group MA.27 Postmenopausal Breast Cancer Trial of Exemestane Versus Anastrozole.

Purpose: ASCO/College of American Pathologists guidelines recommend reporting estrogen receptor (ER) and progesterone receptor (PgR) as positive with (1%-100%) staining. Statistically standardized quantitated positivity could indicate differential associations of positivity with breast cancer outcomes.

Methods: MA.

Efficacy and safety of pentosan polysulfate sodium in people with symptomatic knee osteoarthritis and dyslipidaemia: protocol of the MaRVeL trial.

Introduction: Knee osteoarthritis (OA) is the most prevalent arthritis type and a leading cause of chronic mobility disability. While pain medications provide only symptomatic pain relief; growing evidence suggests pentosan polysulfate sodium (PPS) is chondroprotective and could have anti-inflammatory effects in knee OA. This study aims to explore the efficacy and safety of oral PPS in symptomatic knee OA with dyslipidaemia.

Effects of pulmonary rehabilitation on functional and psychological parameters in post-acute sequelae of SARS-CoV-2 infection (PASC) patients.

Background: COVID-19 survivors may develop long-term symptoms of fatigue, dyspnea, mental health issues, and functional limitations: a condition termed post-acute sequelae of COVID-19 (PASC). Pulmonary rehabilitation (PR) is a recommended treatment for PASC; however, there is a lack of data regarding PR's effect on multiple health indices and the factors that influence patient outcomes. The aim of our study is to evaluate the impact of pulmonary rehabilitation on functional and psychological parameters in patients diagnosed with Post-Acute Sequelae of SARS-CoV-2 Infection (PASC), thereby offering insights into the efficacy of such interventions in improving the quality of life and clinical outcomes for these individuals.

Plasma versus Tissue Tumor Mutational Burden as Biomarkers of Durvalumab plus Tremelimumab Response in Patients with Metastatic Colorectal Cancer in the CO.26 Trial.

Purpose: Tissue-derived tumor mutation burden (TMB) of ≥10 mutations/Mb is a histology-agnostic biomarker for the immune checkpoint inhibitor (ICI) pembrolizumab. However, the dataset in which this was validated lacked colorectal cancers (CRC), and there is limited evidence for immunotherapy benefits in CRC using this threshold.

Patients And Methods: CO.

An Indian surgeon's perspective on management of asymptomatic gallstones.

Introduction: Cholelithiasis is widely prevalent in India, with a majority of patients being asymptomatic while a small proportion experiencing mild complications. In the laparoscopic era, the rate of cholecystectomies has increased owing to early recovery and fewer complications. In asymptomatic patients, the risk of complications must be balanced against the treatment benefit.

Innovative blood transfusion strategies to address global blood deserts: a consensus statement from the Blood Delivery via Emerging Strategies for Emergency Remote Transfusion (Blood DESERT) Coalition.

In rural settings worldwide, many people live in effective blood deserts without access to any blood transfusion. The traditional system of blood banking is logistically complex and expensive for many resource-restricted settings and demands innovative and multidisciplinary solutions. 17 international experts in medicine, industry, and policy participated in an exploratory process with a 2-day hybrid seminar centred on three promising innovative strategies for blood transfusions in blood deserts: civilian walking blood banks, intraoperative autotransfusion, and drone-based blood delivery.
