 Gastro-esophageal reflux disease (GERD) is prevalent and causes erosive esophagitis (EE) with varying degrees of severity (A to D according to the Los Angeles Classification). Adherence to medical therapy is crucial for treatment success. We compared adherence to treatment recommendations between patients with EE grades C/D and A/B.

Venous thromboembolism (VTE) is a frequent complication in patients with cancer and a leading cause of morbidity and death. The objective of the RIETECAT study was to compare the long-term effectiveness and safety of enoxaparin versus dalteparin or tinzaparin for the secondary prevention of VTE in adults with active cancer.

We describe the longitudinal kinetics of the serological response in COVID-19 recovered patients over a period of 14 months. 

Plastic surgery is a broad field that requires a mixed skillset. Therefore, it is important that students be exposed to all its various subspecialties to make informed career decisions and to properly refer patients in different clinical situations. A nationwide survey was conducted of Israeli medical students to investigate their knowledge and perceptions regarding the field of plastic surgery and its subspecialties, and the impact of a clinical rotation in plastic surgery on these factors.

Technical note

Rapid, highly sensitive, and high-throughput detection of biomarkers at low concentrations is invaluable for early diagnosis of various diseases. In many highly sensitive immunoassays, magnetic beads are used to capture fluorescently labeled target molecules. The target molecules are then quantified by detecting the fluorescent signal from individual beads, which is time consuming and requires a complicated and expensive detection system. Here, we demonstrate a high-throughput optical modulation biosensing (ht-OMB) system, which uses a small permanent magnet to aggregate the beads into a small detection volume and eliminates background noise by steering a laser beam in and out of the cluster of beads. 

Fibromyalgia is characterized by diffuse musculoskeletal pain and fatigue. There are limited data about systemic steroid treatment of patients with fibromyalgia in the English literature. Patients with fibromyalgia with ongoing diffuse musculoskeletal pain despite standard treatment, extreme fatigue and elevated C-reactive protein (CRP) levels without evidence of synovitis, or other source of inflammation, were asked to participate in our study.

T cells are critical in the pathogenesis of systemic lupus erythematosus (SLE) by secreting inflammatory cytokines, helping autoantibody production, and forming autoreactive memory T cells. Previous studies have demonstrated their contributions in several forms of organ-mediated damage in SLE, but the role of T cells in neuropsychiatric lupus, the diffuse central nervous system manifestations observed in 20-40% of SLE patients, is not known. Therefore, we evaluated how behavioral deficits are altered upon depletion or transfer of T cells to directly assess the role of T cells in neuropsychiatric systemic lupus erythematosus (NPSLE).

Cognitive-motor interference is a common method used to investigate the cognitive demands of human walking. Using this methodology, consistent effects emerge: under cognitive load, walking velocity decreases, while spatio-temporal variability of walking increases. These effects are often interpreted as indicative of an interference in the ability to control gait. However, walking velocity is highly correlated with most gait parameters; thus, the increase in variability does not necessarily reflect reduced control, but rather a constant signal-to-noise ratio. To investigate the effect of cognitive loading on gait variability, we retrospectively analysed 3721 records of healthy young adults, walking with and without a concurrent cognitive task, on a treadmill.

Patients with advanced salivary gland malignancies (SGCs) have few therapy options. Although results from newly published trials suggest that checkpoint inhibition may be useful in a subgroup of patients, there are no clear criteria for PD-L1 score in SGCs. Chemotherapy benefits were observed to be limited, with a dismal prognosis in unresectable and high-grade SGC. Immunotherapies have demonstrated extraordinary efficacy in a variety of cancers, including non-small cell lung cancer and malignant melanoma. Anti-PD-1 antibody pembrolizumab has been shown to have potent anti-tumor action in a number of clinical trials. We report a unique case of advanced high grade mucoepidermoid carcinoma of the parotid salivary gland after Pembrolizumab treatment as a first line therapy. 

Mitochondria play central roles in maintaining cellular metabolic homeostasis, cell survival and cell death, and generate most of the cell's energy. Mitochondria maintain their homeostasis by dynamic (fission and fusion) and quality control mechanisms, including mitophagy, the removal of damaged mitochondria that is mediated mainly by the Pink1/Parkin pathway. Pink1 is a serine/threonine kinase which regulates mitochondrial function, hitherto many molecular mechanisms underlying Pink1 activity in mitochondrial homeostasis and cell fate remain unknown. Peptides are vital biological mediators that demonstrate remarkable potency, selectivity, and low toxicity, yet they have two major limitations, low oral bioavailability and poor stability. Herein, we rationally designed a linear peptide that targets Pink1 and, using straightforward chemistry, we developed molecular probes with drug-like properties to further characterize Pink1

In several countries, no gender identity- and sexual orientation-related data is routinely collected, if not for specific health or administrative/social purposes. Implementing and ensuring equitable and inclusive socio-demographic data collection is of paramount importance, given that the LGBTI community suffers from a disproportionate burden in terms of both communicable and non-communicable diseases. To the best of the authors' knowledge, there exists no systematic review addressing the methods that can be implemented in capturing gender identity- and sexual orientation-related data in the healthcare sector. A systematic literature review was conducted for filling in this gap of knowledge. 

The immune system matures throughout childhood to achieve full functionality in protecting our bodies against threats. The immune system has a strong reciprocal symbiosis with the host bacterial population and the two systems co-develop, shaping each other. Despite their fundamental role in health physiology, the ontogeny of these systems is poorly characterized. In this study, we investigated the development of the BCR repertoire by analyzing high-throughput sequencing of their receptors in several time points of young C57BL/6J mice. In parallel, we explored the development of the gut microbiome. 

There is a paucity of data regarding sex differences in the profiles and outcomes of ambulatory patients on LVAD support who present to the emergency department (ED). We performed a retrospective analysis of 57,200 LVAD-related ED patient-encounters from the 2010-2018 Nationwide Emergency Department Sample.
