Kaposi's sarcoma (KS), is an AIDS-associated neoplasm caused by the KS herpesvirus (KSHV/ HHV-8). KSHV-induced sarcomagenesis is the consequence of oncogenic viral gene expression as well as host genetic and epigenetic alterations. Although KSHV is found in all KS-lesions, the percentage of KSHV-infected (LANA+) spindle-cells of the lesion is variable, suggesting the existence of KS-spindle cells that have lost KSHV and proliferate autonomously or via paracrine mechanisms. A mouse model of KSHVBac36-driven tumorigenesis allowed us to induce KSHV-episome loss before and after tumor development.

The aims of the study were to examine the degree of compliance with international quality measures for colposcopy in Israel, which does not currently have formal guidelines and to compare the achievement of quality measures between clinical settings.

Oral mucositis (OM) is a common debilitating dose-limiting toxicity of cancer treatment, including hematopoietic stem cell transplantation (HSCT). We hypothesized that the oral microbiome is disturbed during allogeneic HSCT, partially accounting for the variability in OM severity. 

The Cleveland Clinic Incontinence Score, known as the Wexner Score (WS), is a simple, disease-specific questionnaire for anal incontinence (AI) assessment. We aimed to translate and validate a Hebrew version of the WS.

The COVID-19 is disproportionally affecting the poor, minorities and a broad range of vulnerable populations, due to its inequitable spread in areas of dense population and limited mitigation capacity due to high prevalence of chronic conditions or poor access to high quality public health and medical care. Moreover, the collateral effects of the pandemic due to the global economic downturn, and social isolation and movement restriction measures, are unequally affecting those in the lowest power strata of societies. To address the challenges to health equity and describe some of the approaches taken by governments and local organizations, we have compiled 13 country case studies from various regions around the world.

There is increasing awareness of the need to consider potential long-term effects of antibiotics on the health of children. In addition to being associated with immune and metabolic diseases, there is evidence that early-life antibiotic exposure can affect neurodevelopment. Here we investigated the effect of low dose of penicillin V on mice when administered for 1 week immediately prior to weaning.

Evaluates the influence of a half day, hands-on, workshop on detection and repair of Obstetric Anal Sphincter Injuries (OASI).

Atrial fibrillation (AF) is common and bears a major clinical impact in patients with hypertrophic cardiomyopathy (HCM). We aimed to investigate the use and real-world safety of catheter ablation for AF in patients with HCM. 

The selective BRAF and MEK inhibitors (BRAFi+MEKi) have substantially improved the survival of melanoma patients with BRAF V600 mutations. However, BRAFi+MEKi can also cause severe or fatal outcomes. We aimed to identify and compare serious adverse events (sAEs) that are significantly associated with BRAFi+MEKi. 

With repeated practice, learned actions become more skilled, and eventually highly stereotypical. This transition is accompanied by a shift in striatal control over behavior from ventral and dorsomedial striatum to dorsolateral striatum. The cholinergic interneurons (CINs) in the striatum are central to striatal computation. Yet, their role in the transition from motivated to stereotypic behavior is still unclear. In this study we examined whether CINs contribute to the competition between both control systems.

Vestibulectomy is one of the only proven therapeutic treatments for provoked vulvodynia (PVD). However, little is known about long-term surgical success. Patients who underwent vestibulectomy between 1991 and 2003 were interviewed to assess frequency of intercourse and degree of pain during various activities, as well as satisfaction with and willingness to recommend the surgery. We also examined the outcome relation to PVD type being primary or secondary. Differences in pain over time were assessed using a paired-sample t test or a Wilcoxon signed-rank test.

High voltage electrical injury (HVEI) of more than 1000 V is a potentially devastating form of a multisystem injury associated with high morbidity and mortality. We present the first case of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) as a life saving device for treating a patient with severe cardiogenic shock after a high voltage electrical injury.
