Background: The association between new-onset atopic dermatitis (AD) and the coronavirus disease 2019 (COVID-19) pandemic was scarcely documented in the literature.

Objectives: To evaluate the incidence of AD in a large nation-wide cohort over 6 years, focusing on changes in incidence following the onset of the COVID-19 pandemic.

Methods: This retrospective cohort study included all members of the largest HMO in Israel (n=4.8 million) from 2017 to 2022. Patients with newly diagnosed AD were identified using the ICD-10 code for AD (L20). Incidence rates were calculated as the number of new diagnoses per 1000 person-years. The pre-COVID period was 1/2017 to 1/2020, and post-COVID 2/2020 to 12/2022. Age-adjusted incidence rates were calculated based on the World Health Organization's standard population.

Results: The overall crude incidence of AD across the study period was 3.38/1000 person-years (PYs). From 2017 to 2022, there was a 36.97% increase in the crude incidence and a 40.44% increase in the age-adjusted incidence, with a mean annual incidence change of +6.5% and +7.1%, respectively. Both crude and adjusted annual incidence increases were significant (P < 0.001, R² = 0.98; P < 0.001, R² = 0.99, respectively). The incidence of AD at the follow-up before the COVID-19 pandemic was 3.07/1000 PYs, and after was 3.71/1000 PYs.

Conclusions: We observed a significant and nearly consistent annual increase in AD incidence from 2017 to 2022, across various sex and age groups. Further research is needed to explore the impact of the COVID-19 pandemic on rising trends in AD incidence.

Background: Limited data exist regarding the association between marital status and outcomes among octogenarian and nonagenarian patients with heart failure (HF).

Objectives: To examine the association between marital status and outcomes of octogenarian and nonagenarian patients with HF.

Methods: We conducted a retrospective analysis of 1371 octogenarians and nonagenarians who were hospitalized with HF and enrolled in the multicenter national survey in Israel between March and April 2003. The patients were followed until December 2014. Patients were classified into married (n=562) and unmarried (n=809). The clinical characteristics of the patients by marital status categories were compared by using Student's t-test for continuous variables and the chi-square test for categorical variables. Kaplan–Meier survival analysis was used to present survival estimates according to the different marital status categories and the subsequent 4-year survival probability. Multivariate stepwise Cox proportional hazard regression modeling was used to assess the independent predictors of mortality among the study population.

Results: Married patients were more likely to be male, to smoke, and to have past myocardial infarction and previous revascularization. They tended to have higher rates of peripheral vascular disease and dyslipidemia. Survival analysis showed that 4-year mortality rates were similar between married and unmarried patients. The main consistent independent predictors of 4-year mortality were age, advanced HF (New York Heart association (NYHA) > 2), advanced renal failure, low hemoglobin, high Charlson Comorbidity Index, and low admission systolic blood pressure.

Conclusions: Among the octogenarian and nonagenarian population with HF, being unmarried does not confer an increased risk of mortality. Nevertheless, unmarried patients had a different clinical profile. Higher risk profile, co-morbidities, and advanced age impact mortality among octogenarian and nonagenarian patients.

Background: Ramadan, one of the core tenets of Islam, requires a rigorous fasting regimen from dawn until sunset, during which practitioners abstain from all forms of food and drink. This substantial alteration in daily habits raises pertinent questions regarding its potential implications for cardiovascular health.

Objectives: To analyze the incidence of myocardial infarction (MI) throughout the Ramadan fasting period.

Methods: We retrospectively compared the incidence of MI occurring during Ramadan with that observed during the corresponding non-Ramadan months from 2010 to 2021 using medical records of Muslim patients admitted to the Galilee Medical Center. Ramadan's timing varies from year to year. We used a 3-year comparative framework to ensure seasonal alignment.

Results: During the study period and within a well-defined geographic region, we found that among Muslims, there were 405 MIs: 201 during Ramadan and 204 during non-Ramadan periods, P = 0.282.

Conclusions: The incidence of MI during Ramadan remained stable, indicating that the fasting practice does not significantly heighten the risk of MI.

Background: Remnant cholesterol (RC), the cholesterol content of triglyceride-rich lipoproteins, is an emerging residual risk factor for atherosclerotic cardiovascular disease. Data on the prognostic significance after an ischemic stroke are limited.

Objectives: To investigate the association between RC and risk for cardiac events following hospitalization for an ischemic stroke.

Methods: Data were collected for 5697 patients (39.5% women) affiliated with Clalit Health Services and hospitalized with an acute ischemic stroke. Adjusted Cox-regression models were used to estimate the association between RC percentiles, calculated using a routine post-discharge lipid profile, and risk for future myocardial infarction (MI) or coronary revascularization.

Results: Mean age was 69 ± 10 years; 78% were treated by lipid-lowering therapies. During median follow-up of 22 months, a MI or coronary revascularization event occurred in 243 patients. After multivariable adjustment including lipid-lowering therapies and non-HDL-C, RC was associated with higher MI or revascularization risk: hazard ratio (95% confidence interval): 1.42 (1.10–1.85), 1.50 (1.11–2.02), 1.62 (1.09–2.40), and 1.93 (1.22–3.06), in those with RC percentiles ≥ 50th (23.3 mg/dl), ≥ 75th (31.8 mg/dl), ≥ 90th (42.1 mg/dl), and ≥ 95th (49.1 mg/dl), compared to < 50th percentile. When RC and non-HDL-C levels were discordant, the level of RC better reflected higher risk for adverse cardiac events.

Conclusions: Elevated RC following acute ischemic stroke is a risk factor for MI or coronary revascularization, independent of lipid-lowering therapies and non-HDL-C and may serve as a residual cardiovascular risk marker and potential treatment target in patients with ischemic stroke.

Background: Locally advanced gastric adenocarcinomas are treated with neoadjuvant chemotherapy, surgery, and adjuvant chemotherapy. Since 2019 the standard of care for perioperative chemotherapy has been FLOT protocol. Concerns regarding the use of FLOT in elderly patients ≥ 65 years of age emerged due to the relatively high toxicity of this protocol.

Objectives: To evaluate the toxicity profile of FLOT and clinical outcome in elderly patients.

Methods: We conducted a retrospective analysis of patients with locally advanced gastric adenocarcinomas treated with FLOT between 2017–2023 at the Sheba Medical Center. The cohort was stratified by age (≥ or < 65 years). The primary outcome was overall survival (OS). Secondary outcomes were treatment-related toxicity. Kaplan-Meier analysis and Cox proportional hazard regression model were used to analyze the effect of exposure variables on OS.

Results: The study cohort included 91 patients. The median age was 60 years (IQR 50–67); 32 patients were included in the ≥ 65 years group, and 59 patients were included in the < 65 years group. Median follow-up was 40 months (IQR 17–58). Patients ≥ 65 years old received fewer cycles of FLOT compared to those < 65 years old (4.5 vs. 7 cycles, respectively, P = 0.03). Despite the difference in treatment intensity and cumulative chemotherapy dose, there was no difference in median OS between patients ≥ 65 years old compared with those < 65 years old (P = 0.68).

Conclusions: Elderly patients with locally advanced gastric adenocarcinomas received fewer cycles of perioperative FLOT without compromising clinical outcomes.

Background: Increased utilization of imaging modalities has led to a significant rise in the detection of incidental thyroid nodules (ITN). Discrepancies in the prevalence of thyroid nodules with malignant potential exist worldwide.

Objectives: To analyze demographic and clinical data among patients with thyroid nodules in our geographic region.

Methods: The medical records of patients diagnosed with symptomatic or incidental thyroid nodules at the Galilee Medical Center between 2018 and 2023 were reviewed. Demographic and clinical data were collected and analyzed.

Results: The study population included 402 patients with thyroid nodules, 292 females. Symptomatic patients were younger (mean age 55.9 vs. 60.8 years) and had larger nodules (mean size 2.5 vs. 2.1 cm) compared to incidentally diagnosed patients (P < 0.001, P < 0.001, respectively). Male patients demonstrated a higher rate of malignancy for both symptomatic and incidental nodules compared to females (P < 0.05). Pathological examination revealed that malignant nodules were smaller (mean size 2.10 cm vs. 2.87 cm) and detected at a younger age (mean age 48.56 years vs. 56.5 years), compared to benign nodules (P < 0.05, P < 0.01, respectively).

Conclusions: We found a higher prevalence of both symptomatic and ITN among females. However, malignant thyroid nodules were more frequently observed in males. Notably, malignant nodules tended to be smaller and were more commonly diagnosed in younger individuals compared to benign nodules. These findings highlight significant sex and age disparities in the occurrence and characteristics of thyroid nodules, emphasizing the need for tailored diagnostic and management strategies.

Background: The benefits of corticosteroid administration for suspected premature birth (PTB) are widely accepted. Although a single course of antenatal corticosteroids is generally considered to be safe, there are concerns regarding the safety and benefit of multiple courses. Nevertheless, many women who present with symptoms of PTB do not deliver early.

Objectives: To assess how often we used corticosteroid appropriately in our clinical practice in women who presented with risk of PTB.

Methods: Clinical data were retrospectively collected on patients who were admitted to our clinic between September 2014 and August 2015 due to risk of PTB and who were treated with prenatal corticosteroids.

Results: We identified 305 patients at risk of PTB who were treated with corticosteroids; 42.3% delivered < week 34, 22.5% delivered between weeks 34 and 37, and 35.1% delivered > 37 weeks. In women who delivered after week 37, the more time that elapsed between corticosteroids administration and delivery, the lower the pH and the APGAR scores were. Only 26% of patients delivered 2–14 days after the last steroids course of treatment.

Conclusions: The rate of term deliveries at our center after receiving antenatal corticosteroids due to prior symptoms of preterm labor was 35.1%. The ratio of maternal antenatal corticosteroid administration for potential versus actual PTB at < 37 weeks of gestation was not optimal but acceptable.

Background: Hypofractionation regimens shorten the overall duration of treatment, thereby reducing the risk of accelerated tumor cell repopulation following the initiation of radiotherapy. These regimens have been shown to improve overall survival and locoregional control in patients with laryngeal cancer. The toxic effects from radiotherapy for laryngeal squamous cell carcinoma (SCC) include dysphagia, mucositis, laryngeal edema, weight loss, and pain.

Objectives: To evaluate early toxicity and opioid usage associated with hypofractionation treatment of the larynx compared to standard fractionated radiotherapy.

Methods: We retrospectively analyzed 127 laryngeal SCC patients who underwent radiotherapy. Among these, 50% with early glottic cancer received hypofractionation (2.25 Gy per fraction, totaling 63 Gy) directed at the larynx, while 50% with advanced-stage disease underwent standard fractionation (2 Gy per fraction, totaling 70 Gy) targeting both the larynx and bilateral neck, with or without concurrent chemotherapy.

Results: Patients in the hypofractionation group required significantly higher dosages of opioids due to increased pain and swallowing discomfort (P < 0.05). Those in the hypofractionation group who received dexamethasone boluses experienced significantly less weight loss compared to hypofractionation patients who did not receive steroids, with some even experiencing weight gain (P < 0.005). Patients with advanced-stage cancer treated with chemoradiotherapy exhibited greater toxicity than those receiving radiotherapy alone.

Conclusions: Patients undergoing hypofractionation treatment generally require significantly higher doses of opioids than those treated with standard fractionation. Treatment protocols for patients receiving hypofractionation should include effective pain management strategies and, where feasible, the use of corticosteroids.

Background: Epidemiological studies have demonstrated an association between sleep deprivation (SD) and ischemic heart disease.

Objectives: To determine the effect of SD on the endothelial function and on the inflammatory profile of young healthy men following 24 hours of work without sleep.

Methods: Fourteen healthy men (age 31.3 ± 2.4 years) participated in our prospective study. Endothelial function was evaluated by the brachial artery method, measuring flow medicated percent change (FMD%) of the brachial artery by a linear array ultrasound early in the morning. Interleukin 1 (IL-1) and interleukin 6 (IL-6) were measured in saliva by ELISA.

Results: Basic FMD% was 6.7 ± 6.8%, and following SD 1.7 ± 3.3% (P = 0.009). A 5.0 ± 6.1% decrease was measured after SD. IL-1 levels increased after SD from 36 ± 21 pg/ml to 47 ± 24 pg/ml (P = 0.004), and IL-6 levels increased from 22 ± 07 pg/ml to 36 ± 11 pg/ml (P = 0.0005). A negative correlation was found between the change (decrease) in FMD% and the change (increase) in IL-1 level (r = -0.813; P = 0.001). A negative correlation was found between the decrease in FMD% and the increase in IL-6 level (r = -0.735; P = 0.003).

Conclusions: SD led to endothelial dysfunction with increase in markers of inflammation (IL-1 and IL-6), with an inverse correlation between the change (decrease) in endothelial function and the change (increase) in IL-1 and in IL-6.

Ventriculoperitoneal shunt (VPS) placement is a standard treatment for pediatric hydrocephalus. However, infection remains a significant complication, occurring in 5–27% of cases, with coagulase-negative staphylococci (CONS) and Staphylococcus aureus being the most common pathogens [1]. Current guidelines recommend empirical antibiotic treatment and surgical removal of the infected shunt [2]. While shunt removal and replacement are recommended for managing shunt infections, these procedures subject the child to the risks associated with multiple surgeries. However, recent approaches have suggested that in certain cases antibiotics alone may suffice, thus avoiding the risks of surgery [3].

We describe two children with VPS infections caused by CONS who were successfully treated with vancomycin and rifampicin alone, without the need for shunt removal.

Pre-Ramadan fasting planning before the month of Ramadan represents a golden opportunity for better glucose control during the month of Ramadan among patients with type 2 diabetes mellitus (T2DM). Pre-Ramadan begins 1–2 months earlier and represents a crucial period when healthcare practitioners can provide medical instructions, risk assessment, and stratification to minimize the associated risks such as postprandial hyperglycemia and hypoglycemia during Ramadan fasting. This review focuses on two important classes of drugs that are widely used in Israel incretin-based therapy, particularly the glucagon-like peptide-1 receptor (GLP-1Rc) agonists class and the sodium-glucose cotransporter-2 inhibitors (SGLT-2i) class. In addition, we provide data regarding specific populations such as elderly patients and Bedouins living in the Negev area who require specific recommendations for safe Ramadan fasting. Our data are based on previously published guidelines, consensus statements, and our experience.

The long-standing Iran–Israel conflict escalated sharply in April 2024, with Iran’s attack on Israeli territory (13–14 April) and Israel’s retaliation in Isfahan (19 April) [1]. As predicted, a full-scale war erupted between 13–24 June 2025 involving direct strikes on sovereign land and vital infrastructure.

The escalating complexity of healthcare delivery underscores the demand for digital transformation in medicine. Among impactful innovations, artificial intelligence (AI)-driven scheduling solutions are being developed and deployed [1].

Safra Children’s Hospital at Sheba Medical Center is Israel’s first medical institution to implement an AI-powered scheduling platform (Equina Scheduling: https://www.equinascheduling.com/). Equina was selected for its capacity to handle the complex, rule-based environment of a training program in a tertiary pediatric hospital. Comprising approximately 70 residents, our pediatric residency program is among the nation's largest. The program manages approximately 1500 monthly shifts, encompassing 49 distinct service shifts, 22 diverse training shifts, and more than 20 different block rotations.
