Non-carbapenemase-producing carbapenem-resistant (non-CP CRE) may be associated with a grave outcome. The common underlying mechanism is beta-lactamases and mutations in outer membrane porins. We report a case of a deep-seated infection caused by ST395 not amenable to source control, involving recurrent bloodstream infection, resulting in selection of carbapenem resistance under therapy.

Highly variable estimates of COVID-19-associated fungal diseases (IFDs) have been reported. We aimed to determine the incidence of clinically important fungal diseases in hospitalized COVID-19 patients during the first year of the pandemic. We performed a multicenter survey of IFDs among patients hospitalized with COVID-19 in 13 hospitals in Israel between February 2020 and May 2021.

Background: is a small cell-wall-free organism, part of the normal microbiota of the genitourinary tract. It is rarely involved in extragenital infections, mainly joint, surgical-site, and respiratory infections.

Methods: We describe a case of subdural empyema and lower limb surgical site infections, following decompressive craniotomy, after traumatic brain and extremities injury.

Unlabelled: An increasing number of studies have tried to determine the incidence of invasive fungal infections (IFIs) in COVID-19 patients. Challenges in the diagnosis of pulmonary aspergillosis in these patients have led to new definitions of COVID-19-associated pulmonary aspergillosis (CAPA). The aim of this study was to determine the incidence and outcomes of and risk factors for IFIs in critically-ill COVID-19 patients, using the new definitions, in a tertiary center in Israel.

People's posting behaviors in social networks was perceived as ambiguous, with concerns misaligned with people's public postings. To address this gap, we suggest a model that offers new insights into the relationship between perceptions and actual behaviors. We define a quantitative marker for agility, the frequency in which people update their audience selection when posting information in online social networks, and evaluate the factors that contribute to the variability of agility between different users.

Sir William Osler is considered to be one of the fathers of modern medicine who pioneered the practice of bedside teaching of clinical medicine for medical students and residents. Osler was well known as a diagnostician and outstanding therapist with a humanized approach and rare didactic capabilities. Medical training at Hadassah is built on the central tenets of Osler's approach, incorporating the tremendous advances in science and medicine.

The five complexes of the mitochondrial respiratory chain (MRC) supply most organs and tissues with ATP produced by oxidative phosphorylation (OXPHOS). Inherited mitochondrial diseases affecting OXPHOS dysfunction are heterogeneous; symptoms may present at any age and may affect a wide range of tissues, with many diseases giving rise to devastating multisystemic disorders resulting in neonatal death. Combined respiratory chain deficiency with normal complex II accounts for a third of all respiratory deficiencies; mutations in nuclear-encoded components of the mitochondrial translation machinery account for many cases.
