COVID-19 exerts deleterious cardiopulmonary effects, leading to a worse prognosis in the most affected. This retrospective multi-center observational cohort study aimed to analyze the trajectories of key vitals amongst hospitalized COVID-19 patients using a chest-patch wearable providing continuous remote patient monitoring of numerous vital signs.

This study was developed to explain the extraordinary rise in myopia prevalence beginning after 1950 in Indigenous Arctic communities considering recent findings about the risk factors for school myopia development. Myopia prevalence changed drastically from a historical low of less than 3% to more than 50% in new generations of young adults following the Second World War. At that time, this increase was attributed to concurrent alterations in the environment and way of life which occurred in an aggressive programme of de-culturalization and re-acculturation through residential school programmes that introduced mental, emotional and physical stressors. However, the predominant idea that myopia was genetic in nature won the discussion of the day, and research in the area of environmental changes was dismissed. There may have also been an association between myopia progression and the introduction of extreme mental, emotional and physical stressors at the time.

Hereditary spherocytosis (HS) is the most common inherited hemolytic anemia. The flow cytometric test using eosin-5'maleimide (EMA) is a well-established diagnostic method. However, in order to improve HS detection, it is recommended that EMA and an osmotic fragility test (OFT) both be performed. OFT is time consuming and labor intensive. We used a flow cytometric (FOFT) adaptation of the classical OFT reported by Yamamoto. We compare the FOFT to the classical OFT including practical data and propose options for simplifying this method.

Tracheostomy is an aerosol-generating procedure, thus performing it during the COVID-19 pandemic arises considerations such as the most appropriate timing and the patients to whom it is suitable. Medical teams lack sufficient data to assist determining whether or not to conduct tracheostomy, its short- and long-term implications are not fully understood. This study aims to shed light on the critically ill COVID-19 patients that require tracheostomy, and to investigate its value.

Red blood cell transfusion (RBCT) is a therapeutic procedure with important and undesirable secondary effects. Inappropriate overuse of RBCT is significant, and a significant percentage of physicians prescribe RBCT unnecessarily. Patient involvement in treatment decision-making is poor worldwide. Shared (with the patient) transfusion decision-making (TrDM) can temper a "quick finger on the trigger" of blood transfusion (BT). The objective of this study was to determine patients' preferences surrounding their involvement in the TrDM process as well as physicians' willingness to involve the patient in TrDM. The study also determined the role of patient age, gender, ethnicity, and schooling years in the TrDM process

The association between body mass index (BMI) and clinical outcomes following an acute myocardial infarction (AMI) remains controversial. Our objective was to investigate the relationship between BMI and AMI presentation, in-hospital clinical course and mortality in the contemporary era of AMI management.

Following their first interaction with the antigen, quiescent naive T-helper (Th; CD4⁺) cells enlarge, differentiate, and proliferate; these processes are accompanied by substantial epigenetic alterations. We showed previously that the epigenetic regulators the polycomb-group (PcG) proteins have a dual function as both positive and negative transcriptional regulators; however, the underlying mechanisms remain poorly understood. Here, we demonstrate that during Th cell differentiation the methyltransferase activity of the PcG protein Ezh2 regulates post-transcriptionally inducible assembly of intranuclear actin filaments.

The 23-valent pneumococcal vaccine is recommended for people aged 65 years and over, to prevent pneumonia, a leading cause of infectious morbidity in older people. This study assessed pneumococcal vaccination in people aged 65-74 years living in northern Israel who were eligible for the pneumococcal vaccine since introduction free of charge. 

Characterizes the fecal microbiome in newly diagnosed prostate cancer patients.

Medical cannabis (MC) is becoming increasingly popular for the treatment of chronic pain conditions. In this study, we evaluated the effect of MC treatment on pain level and quality of sleep of patients with different medical conditions at the rheumatology clinic.

The aim of the current study was to establish whether the vertebral morphometry (e.g., vertebral body width and spinal canal diameters) is associated with degenerative lumbar spinal stenosis (DLSS). 

Die besonderen Charakteristika von Patienten mit bullösem Pemphigoid (BP) mit Schleimhautbeteiligung sind weitgehend unbekannt. Unser Ziel war die Erforschung der klinischen und immunologische Charakteristika von BP-Patienten mit Schleimhautbeteiligung, um Faktoren zu identifizieren, die mit Schleimhautläsionen assoziiert sind.

Atopic dermatitis, known also as atopic eczema, represents a commonly diagnosed, chronic or recurrent/relapsing inflammatory disorder. From a clinical point of view, it is characterized by acute flare-ups of intense itching, eczematous pruritic lesions involving dry skin. Dupilumab is the only biologic agent approved to treat moderate to severe course of atopic dermatitis, which can be particularly severe during pregnancy causing distress and impacting on maternal and fetal health. However, there is a dearth of data concerning the safety profile of Dupilumab during gestation. (R Khamisy-Farah, G Damiani, J D Kong, J-H Wu, N L Bragazzi)
