We are writing to express our serious concerns and surprise over some of the statements and quotations offered in Richard Horton's Offline about WHO's decision not to publish health statistics for the West Bank and the Gaza Strip in their World Health Statistics 2022....

Extracellular vesicles (EVs) transfer bioactive molecules between cells in a process reminiscent of enveloped viruses. EV cargo delivery is thought to occur by protein-mediated and pH-dependent membrane fusion of the EV and the cellular membrane. However, there is a lack of methods to identify the fusion proteins and resolve their mechanism. We developed and benchmarked an in vitro biophysical assay to investigate EV membrane fusion. 

Pyoderma  gangrenosum (PG) is a  eutrophilic  dermatosis that manifests with rapidly developing, painful skin ulcers characterized by undermined  borders and peripheral erythema. PG is strongly associated with underlying systemic diseases such as inflammatory bowel disease, hematologic malignancies, and inflammatory arthritis. In the current study, we sought to investigate the risk and prognostic outcomes of myocardial infarction (MI), cerebrovascular accident (CVA), peripheral vascular disease (PVD), and pulmonary embolism (PE) among patients with PG.

An inactivating PHEX gene mutation with the resultant accumulation of several mineralization-inhibiting proteins (e.g., FGF23) causes skeletal and dental morbidity in X-linked hypophosphatemia (XLH). This prospective case-control study explored the effect of burosumab, an anti-FGF23 antibody, on dental health of children with XLH. 

Leptothrix are long bacteria of rare occurrence; although these bacteria have been implicated in causing vaginal symptoms identical to candidiasis, studies on prevalence and effect on overall vaginal health are lacking. In this study, we evaluated data of women referred to a private clinic for treating vulvovaginal symptoms (n = 1847) and reassessed data of our previous and ongoing studies (n = 1773). 

Divers are regularly exposed to a unique and changing environment that dentists must consider when treating such patients. This review focuses around two case studies encountered in naval dentistry: (i) diving barotrauma (pressure-induced injury related to an air space); and (ii) scuba diving mouthpiece-related oral conditions.

The non-receptor focal adhesion kinase (FAK) is highly expressed in the central nervous system during development, where it regulates neurite outgrowth and axon guidance, but its role in the adult healthy and diseased brain, specifically in Alzheimer's disease (AD), is largely unknown. Using the 3xTg-AD mouse model, which carries three mutations associated with familial Alzheimer's disease (APP KM670/671NL Swedish, PSEN1 M146V, MAPT P301L) and develops age-related progressive neuropathology including amyloid plaques and Tau tangles, we describe here, for the first time, the in vivo role of FAK in AD pathology. 

Arginases are often overexpressed in human diseases, and they are an important target for developing anti-aging and antineoplastic drugs. Arginase type 1 (ARG1) is a cytosolic enzyme, and arginase type 2 (ARG2) is a mitochondrial one. In this study, a dataset containing 2115-FDA-approved drug molecules is virtually screened for potential arginase binding using molecular docking against several ARG1 and ARG2 structures.

Ultrasound-guided fine needle aspiration cytology (FNAC US) has been proven to be an accurate and efficient tool in thyroid nodule evaluation. Thyroid nodule aspiration can be acquired with either of two techniques: the short axis, in which only the tip of the needle is observed, and the long axis, in which the entire length of the needle is observed. Our retrospective study aimed to compare the adequacy of the two techniques.

During the COVID-19 pandemic there have been numerous reports of increases in psychiatric morbidity and a deterioration of status among existing patients. There is little information about how this increase has affected youth and rates of adolescent psychiatric hospitalization. Our study was aimed at examining trends in youth psychiatric hospitalization during the first year of the COVID-19 pandemic.

As new variants of SARS-CoV-2 continue to emerge, it is important to assess the cross-neutralizing capabilities of antibodies naturally elicited during wild type SARS-CoV-2 infection. In the present study, we evaluate the activity of nine anti-SARS-CoV-2 monoclonal antibodies (mAbs), previously isolated from convalescent donors infected with the Wuhan-Hu-1 strain, against the SARS-CoV-2 variants of concern (VOC) Alpha, Beta, Gamma, Delta and Omicron.

Gallstone disease is common worldwide and can lead to severe complications, including cholangitis; thus, it is important to identify modifiable risk factors for cholangitis. Proton pump inhibitors (PPIs) are commonly prescribed to treat gastroenterological disorders. We aimed to explore whether PPI use is associated with an increased risk of acute cholangitis in patients with gallstone disease.

During the Syrian civil war, Syrian refugees crossed the Israeli border to receive medical treatment. During this time, Galilee Medical Center (GMC) became the main center for multidisciplinary treatment of these war-wounded patients. This retrospective study compares the demographics of local Israeli and refugee Syrian patients, as well as the volume and types of procedures each group received over a 5-year period. 

Appropriate pain management indicates the quality of casualty care in trauma. Gender bias in pain management focused so far on the patient. Studies regarding provider gender are scarce and have conflicting results, especially in the military and prehospital settings. The purpose of this study is to investigate the effect of health care providers' gender on pain management approaches among prehospital trauma casualties treated by the Israel Defense Forces (IDF) medical teams.

The need for the early identification of SARS-CoV-2 has let to a quest for reliable tests that meet the standards of polymerase chain reaction (PCR) tests, on the one hand, and are low-cost, easy-to-use, and fast, on the other hand. One such test is the Lucira™ Check It COVID-19 Test kit ("Lucira") (Lucira Health, Inc., Emeryville, CA, USA), which utilizes real-time loop-mediated isothermal amplification technology, developed for at-home use. This study evaluated the clinical sensitivity and specificity of Lucira in identifying the virus in 190 nasopharyngeal samples collected between January and October 2021.
