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.

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.

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.

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. 

We aimed to identify a simple metric accounting for peri-procedural hemoglobin changes, independent of blood product transfusion strategies, and assess its correlation with outcomes in patients undergoing left ventricular assist device (LVAD) implantation

Hepatitis D virus may cause a disease at various severities in the presence of hepatitis B virus, using hepatitis B surface antigen (HBsAg) on the external envelope in its replication process. Thus, people identified with HBsAg in blood tests should also be tested for hepatitis D virus. Describes the situation of performance of blood tests for detection of hepatitis D virus in patients positive for hepatitis surface antigen during 9 years in a population with heterogeneous origins in the north region of Israel.

Onychomykose (OM) und Tinea pedis (TP) sind häufige Pilzinfektionen der Haut. Aktuell basiert die Diagnose vornehmlich auf mikroskopischem Direktnachweis und/oder Kultur. Beide Methoden haben jedoch eine geringe bis mäßige Sensitivität und benötigen teilweise mehrere Wochen, bis endgültige Laborergebnisse vorliegen. Um die Diagnose kutaner Pilzinfektionen zu verbessern, wurden PCR-basierte Methoden entwickelt. Hier haben wir hier die Sensitivität und Spezifität einer Chip-basierten Multiplex-PCR mit mikroskopischen Direktnachweis und verglichen.

Google Translate: Onychomycosis (OM) and tinea pedis (TP) are common fungal skin infections. Currently, the diagnosis is primarily based on direct microscopic detection and/or culture. However, both methods have a low to moderate sensitivity and sometimes require several weeks before final laboratory results are available. To improve the diagnosis of cutaneous fungal infections, PCR-based methods have been developed. Here we compared the sensitivity and specificity of a chip-based multiplex PCR with microscopic direct detection.
