Coronavirus disease 2019 (COVID-19) led to two nationwide lockdowns in Israel, reducing both supply and demand for medical services in the Israel Defense Force (IDF). IDF soldiers serve on bases within Israel, and most of them return home at the end of the day, similar to other armies in the world. Objectives: To analyze the health services provided by the IDF with regard to policy changes during lockdowns.

To mitigate the spread of coronavirus disease 2019 (COVID-19), national guidelines, in accordance with international health authorities, mandated 14 days of quarantine for every close contact of a confirmed COVID-19 patient. Although health benefits are obvious, consequences are profound, especially for organizations required to maintain operational preparedness. Objectives: To present the Israel Defense Force (IDF) experience with outbreaks regarding quarantined individuals. To weigh the consequences of quarantined individuals needed for workforce and operation.

In this special issue of Israel Medical Association Journal (IMAJ) is to expose readers to the continuous efforts of the IDF-MC to fulfill its mission by promoting research in multiple medical fields, including trauma, ambulatory care, health administration. In addition, in this issue of IMAJ, authors discuss the unique collaboration with the civilian system during the coronavirus disease 2019 (COVID-19) pandemic. 

Chest trauma is among the most common types of trauma, corresponding to 10% of trauma patients admitted to hospitals. In the military setting, thoracic trauma was reported as a significant cause of death. With well-timed treatment, chest trauma is regarded as survivable. Emergency thoracotomy (ET) is considered when the patient with trauma to the chest needs immediate resuscitation. Survival rate is reported as low as 1% in some reports and 20% in others. The survival rate depends on injury mechanism, protocols for intervention, and other decompressive procedures. Objectives: To determine parameters that may impact survival of ET.

Genistein is an isoflavone naturally present in numerous staple food crops, such as soybeans and chickpeas. This study utilized the Gallus gallus intraamniotic administration procedure to assess genistein administration effects on trace mineral status, brush border membrane (BBM) functionality, intestinal morphology, and intestinal microbiome in vivo. 

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. 

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.

Antibioprohylaxis (ABP) for pancreatic cystic lesion is still a debated clinical indication. Although professional societies guidelines still recommend ABP in endoscopic ultrasound-fine needle aspiration (EUS-FNA) for pancreatic cystic lesions (PCL) this standard of care recommendation was based on old and weakly planned studies with a small number of patients. Herein, in this work, we provide a critical review with pooled data analysis of the available literature. 

Local cervical treatment for squamous intraepithelial lesion (SIL) or cervical intraepithelial neoplasia (CIN) removes or ablates a cone-shaped or dome-shaped part of the cervix that contains abnormal cells. This Series paper introduces the 2022 terminology for cone dimensions after local conservative treatment for SIL, CIN, or early invasive cervical cancer. The terminology was prepared by the Nomenclature Committee of the European Society of Gynaecologic Oncology, the European Federation for Colposcopy, the International Federation of Cervical Pathology and Colposcopy, and the European Society of Pathology. Cone length should be tailored to the type of transformation zone....

Helicopter emergency medical services (HEMS) allow for shorter transport duration in long-distance evacuations and facilitate advanced en-route medical care access. Studies comparing HEMS with ground emergency medical services (GEMS), including the outcome of prehospital mortality, are lacking. This study aimed to evaluate the association between HEMS and early mortality in Israel.

Patients with inflammatory bowel disease (IBD) treated with anti-tumor-necrosis factor-alpha (TNFα) exhibited lower serologic responses one-month following the second dose of the COVID-19 BNT162b2 vaccine compared to those not treated with anti-TNFα (non-anti-TNFα) or to healthy controls (HCs). We comprehensively analyzed long-term humoral responses, including anti-spike (S) antibodies, serum inhibition, neutralization, cross-reactivity and circulating B cell six months post BNT162b2, in patients with IBD stratified by therapy compared to HCs. 

Autoimmune diseases (AIDs) are often co-associated, and about 25% of patients with one AID tend to develop other comorbid AIDs. Here, we employ the power of datamining to predict the comorbidity of AIDs based on their normalized co-citation in PubMed.
