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: 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: 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: Antiphospholipid syndrome (APS) is a common form of acquired thrombophilia associated with a high thrombotic risk. Fabry's disease (FD) is an X-linked lysosomal storage disease caused by mutations in the alpha-galactosidase A (GLA) gene and presents with a wide range of clinical manifestations, including a high rate of thrombosis. Previously reported, 45% of FD patients were found to have antiphospholipid autoantibodies.

Objectives: To determine the prevalence of FD in patients with APS.

Methods: We conducted a prospective study. Data were collected from 41 APS patients at our outpatient clinic at Meir Medical Center in Israel. We utilized chemical and genetic analyses to identify FD among APS patients. Dried blood spot (DBS) was used to assess GLA activity in males, and mutational analysis of the GLA gene was performed by sequencing exons and their flanking regions in women.

Results: Among 41 antiphospholipid patients, one male patient was diagnosed with FD. Gal variants were not detected in any of the tested female patients.

Conclusions: We found a low prevalence (2.4%) of FD in APS patients. Larger studies are needed to evaluate the clinical utility and cost-effectiveness of routine FD screening in this population.

Background: Functional mitral and tricuspid regurgitation (fMR and fTR, respectively) portend increased morbidity and mortality among heart failure (HF) patients.

Objectives: To characterize acute decompensated valvular HF (VHF) as a novel HF category, defined by presence of either more than moderate fTR or more than moderate fMR with left ventricular ejection fraction (LVEF) ≤ 50%.

Methods: Patients with VHF were prospectively enrolled over a 6-month period and compared to acute decompensated heart failure (ADHF) patients without significant fTR or fMR. We used a standardized diuretic protocol when indicated, and appropriate inpatient guideline-directed medical therapy was initiated.

Results: Among 322 patients admitted with ADHF, 83 (26%) met VHF criteria with mean age 66 ± 13 years, 43 (52%) males, and median LVEF of 30% (20-55). Of 61 patients in whom the diuretic protocol was initiated, 59 (97%) had an adequate response (i.e., > 100 cc/hour for at least 6 hours). VHF patients had longer length of hospitalization (8 [5-13] vs. 5 [3-8] days, P < 0.001), and higher rates of 90-day heart replacement therapy (HRT) or death (hazard ratio 2.52, 95% confidence interval (1.13-5.64); P = 0.024).

Conclusions: Over a quarter of ADHF patients can be newly categorized as VHF patients, distinguished by prolonged hospitalization and worse 90-day mortality / HRT rate. The initial response rate to a standardized diuretic protocol was high.
