Background: Fetal macrosomia is a risk factor for operative vaginal delivery (VD), shoulder dystocia, obstructed labor, and cesarean section (CS). Induction of labor (IOL) may decrease these risks but also leads to longer labor, increasing the risk of CS. No data exist regarding the optimal method of IOL in macrosomic fetuses, and most studies are limited to the efficacy of medical induction.

Objective: To compare medical and mechanical IOL in macrocosmic fetuses.

Methods: This retrospective case-control study included pregnant women who underwent IOL and delivered macrosomic neonates at a tertiary center between 2010 and 2020.

Women with non-cephalic presentation, prior CS, and multiple pregnancies were excluded. The primary outcome was the mode of delivery. Secondary outcomes included neonatal and maternal complications.

Results: A total of 247 women were included in the study, 188 underwent cervical ripening with prostaglandin E2 (PGE2) regimens and 59 with a double-balloon catheter. Higher rates of prior deliveries over 4000 grams and Oxytocin use during delivery were found in the mechanical induction group. No other clinically significant differences in demographic or clinical characteristics were identified. There were no statistically significant differences in the rates of VD or CS between the groups. The indications for CS were similar. Maternal and neonatal secondary outcomes were comparable.

Conclusion: PGE2 vaginal regimens and double catheter balloons are safe and effective methods for cervical ripening during IOL in term pregnancies with macrosomic neonates. The choice of cervical ripening method did not impact the mode of delivery or maternal and neonatal outcomes.

Background: Cesarean section (CS) comprised almost one-third of all births. One of the complications after CS is intra-abdominal and pelvic adhesions formation.

Objectives: To investigate whether a previous CS poses an additional perioperative or postoperative risk for complications when performing a total laparoscopic hysterectomy (TLH).

Methods: We conducted a retrospective cohort study of women who had undergone a TLH between 2014 and 2020. Perioperative and postoperative complications were assessed according to the Clavien-Dindo classification system. Descriptive statistics were used to analyze the results.

Results: In total, 190 women underwent TLH during the study period, 50 (26.5%) had a previous CS (study group) and 140 (73.5%) had no history of CS. The complication rates using the Clavien-Dindo classification system were similar in both groups; however, the major complications rate was not significantly higher in the study group (CS 6% vs. no CS 1.4%, P = 0.08). Urethral injury was the most common major complication (2, 4% vs. 1, 0.7%). The duration of surgery (125 min vs. 112 min, P = 0.02), estimated blood loss (174 ml vs. 115 ml, P = 0.02), and additional postoperative endoscopic interventions (4% vs. 0%, P = 0.01) and were significantly greater in patients with a previous CS.

Conclusions: Although the need for postoperative endoscopic interventions, surgery duration, and estimated blood loss were significantly higher in patients with a previous CS, TLH remains a safe and recommended procedure for these patients. Major complications are rare and do not occur more frequently following a previous CS.

Background: Breast reconstruction following oncological resection offers psychosocial benefits. Various factors influence patient reconstruction decisions, including ethnicity, socioeconomic status, and education. We investigated disparities in breast reconstruction among Bedouin and non-Bedouin women in the Negev region.

Objectives: To investigate the influence of ethnicity in breast reconstruction decisions between Bedouin and non-Bedouin women in Israel and to identify factors influencing the choice of reconstruction following oncological breast surgery.

Methods: In this retrospective cohort study, we examined women undergoing breast cancer surgery, with or without reconstruction, between 2015 and 2021 in a breast cancer referral center. Demographics and detailed medical data were collected from electronic health records. We analyzed the factors that influenced decisions regarding breast reconstruction.

Results: The study included 1415 patients who underwent breast resection. Age was a significant factor in breast reconstruction choices, with younger patients being more likely to choose reconstruction. Marital status and education level influenced the decision, whereas socioeconomic status and number of children did not. Ethnicity analysis highlighted distinct demographic and socioeconomic differences between Bedouin and non-Bedouin women. Despite these disparities, surgical choices did not differ significantly between ethnicities.

Conclusions: Significant disparities exist between Bedouin and non-Bedouin women in terms of sociodemographic factors. However, these disparities did not affect their breast reconstruction decisions. Age, marital status, and education level influenced the decision to reconstruct the breast.

Background: Identifying drug–drug interactions (DDIs) in dermatology can be cumbersome and time-consuming using traditional methods.

Objectives: To explore the potential of ChatGPT-4o, an artificial intelligence (AI)-based chatbot, to streamline the identification process.

Methods: ChatGPT-4o was tasked with assessing DDIs among commonly prescribed dermatological medications. The accuracy and reliability of the chatbot's outputs were compared against established references for 43 interactions.

Results: ChatGPT-4o successfully identified all evaluated interactions. It accurately described the interaction effects in 42 cases, with only one example of misdescription.

Conclusions: The findings highlight the potential of ChatGPT to serve as an effective and efficient alternative for identifying and understanding DDIs in dermatology, despite one noted error that emphasizes the need for ongoing verification against trusted references. Further research is needed to validate its use across a broader range of medications and clinical scenarios.

Psoriasis is a chronic, immune-mediated skin disease characterized by inflammatory lesions and systemic co-morbidities. Emerging evidence highlights the significant role of the microbiome in psoriasis pathogenesis. Dysbiosis of the skin and gut microbiota has been linked to increased disease severity and co-morbidities such as psoriatic arthritis and cardiovascular disease. In this review, we explored the microbiome's influence on immune responses in psoriasis and its potential as a therapeutic target. Microbial therapies, such as probiotics and fecal microbiota transplantation, hold promise for restoring microbial balance and improving outcomes. We also discuss how the microbiome modulates drug efficacy and toxicity, offering insights for personalized treatment approaches. While challenges remain in establishing causality and translating findings into clinical practice, leveraging the gut-skin axis may optimize psoriasis management and improve patient outcomes.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease pathway is heavily influenced by different inflammatory cytokines. There is ample evidence of cannabidiol (CBD) immunomodulation effects.

Objectives: To investigate the effect of CBD on patients with SARS-CoV-2 and to measure the impact on inflammatory cytokines.

Methods: A double blind, placebo-controlled study to compare the clinical outcomes and selected serum cytokine levels in patients with SARS-CoV-2 that received sublingual CBD extraction. Seven patients were randomized to the treatment arm and three to the placebo group.

Results: Clinical outcomes were better in the patient group that received sublingual CBD vs. patients receiving placebo treatment. Serum cytokine mean concentration levels showed differences between the two groups but of mixed trends.

Conclusions: Patients presenting with SARS-CoV-2 and receiving CBD sublingually had better outcomes than those receiving a placebo, although these results did not reflect in selected serum cytokines. Further study is needed.

Background: Giant cell arteritis (GCA) is a large vessel vasculitis predominantly affecting patients over 50 years, typically managed with glucocorticoids, with treatment varying on individual patient needs. While effective for GCA, long-term glucocorticoids use poses significant risks, including the development of osteoporosis, a metabolic bone disease common in older individuals. This overlap poses a significant clinical challenge, as the treatment for GCA inadvertently raises the risk of osteoporosis and necessitates careful balance to manage both conditions effectively.

Objectives: To investigate the occurrence of osteoporosis and other co-morbid conditions in patients with GCA treated with glucocorticoids.

Methods: A retrospective cross-sectional analysis of GCA patients examined the correlation between GCA and osteoporosis by searching the Clalit Health Service database for patients over 50 years of age from January 2002 to January 2018. In addition, we conducted a logistic regression analysis stratifying for other co-morbidities to evaluate the independent association between GCA and osteoporosis.

Results: In total, 6607 GCA patients were compared with 36,066 age- and sex-matched controls. The study revealed a higher prevalence of osteoporosis in the GCA group (43%) compared to controls (27%) (odds ratio [OR] 2.06, 95% confidence interval [95%CI] 1.95–2.17). In addition, hypertension, hyperlipidemia, diabetes mellitus, and ischemic heart disease were more prevalent among GCA patients. After stratifying for cardiovascular co-morbidities, GCA remained independently associated with osteoporosis (OR 2.1, 95%CI 1.96–2.26, P < 0.001).

Conclusions: Glucocorticoid-treated GCA is independently associated with osteoporosis. Healthcare providers must consider this added aspect of GCA for the treatment and management of patients.

Late arrival ST-segment elevation myocardial infarction (STEMI) is defined as a patient-related delay > 12 hours. It is estimated to represent a significant portion of STEMI patients. As reflected by society guidelines, this group of patients impose great therapeutic challenge, namely due to controversy in the literature regarding optimal care, together with major adverse clinical outcomes [1]. In addition to a possible myocardial infarction (MI), mechanical complications include ventricular septal defect (VSD), left ventricular (LV) free wall, or papillary muscle rupture. Prompt diagnosis and intervention are crucial to improve outcomes as post-infarction ventricular septal defect (PIVSD) carries a high mortality rate. We describe the successful management of a large VSD complicated by cardiogenic shock in a latecomer STEMI patient with complex coronary artery disease (CAD).

Background: According to Hamas sources, many Israeli hostages in Gaza were killed by indiscriminate Israeli airstrikes, together with a large number of Palestinian citizens.

Objectives: To verify whether the estimated death rate of Israeli hostages was similar to the estimated death rate of Gaza citizens from these acts of war.

Methods: We used two estimates of hostage death rates, one obtained from Israeli intelligence sources, and one published by a Hamas spokesperson. We used the Palestinian casualty rates published by the Palestinian Ministry of Health. We compared death rates using Fisher's exact test.

Results: By 30 December 2023, the rate of Israeli hostage death was 23/238 (9.7%) according to Israeli intelligence sources, and 60/238 (25.2%) according to Hamas. Both figures are strikingly and significantly higher than the death rate among Palestinians, estimated to be 19,667/2.2 million (0.89%) by 19 December 2023 (P < 0.0001).

Conclusions: Israeli airstrikes as the cause of death of Israeli hostages are implausible unless they were specifically exposed to these strikes more than Palestinian citizens.

Carbamoyl phosphate synthetase 1 (CPS1; MIM *608307; E.C. 6.3.4.16) is the first rate-limiting enzyme of the urea cycle, an essential metabolic pathway for ammonia detoxification. CPS1 deficiency (CPS1-D) is characterized by severe hyperammonemia during disease exacerbations. During a metabolic crisis, children with CPS1-D are admitted with vomiting, altered mental status, and high serum levels of ammonia. Rapid normalization of ammonia level ameliorates neurological outcome [1,2]. The first-line treatment for hyperammonemia in these patients is ammonia scavengers in combination with citrulline or arginine and high-calorie supplementation while controlling protein intake [1].

Background: Existing cardiac disease contributes to poor outcome in patients with coronavirus disease 2019 (COVID-19). Little information exists regarding COVID-19 infection in patients with a cardiac implantable electronic device (CIED).

Objectives: To assess the association between CIEDs and severity of COVID-19 infection.

Methods: We performed a retrospective analysis including 13,000 patients > 18 years old with COVID-19 infection between January and December 2020. Patients with COVID-19 who had a permanent pacemaker or defibrillator were matched 1:4 based on age and sex followed by univariate and multivariate analyses. Baseline characteristics and clinical outcomes were assessed.

Results: Forty patients with CIED and 160 patients without CIED were included in the current analysis. Mean age was 72.6 ± 13 years, and approximately 50% were females. Majority of the patients in the study arm had a pacemaker (63%), whereas only 15 patients (37%) had a defibrillator. Patients with COVID-19 and CIED presented more often with atrial fibrillation, coronary artery disease, heart failure, hypertension, diabetes, and chronic kidney disease. They were more likely to be hospitalized in the intensive care unit (ICU) and required more ventilatory support (35% vs. 18.3%). Thirty-day mortality (22.5% vs. 13.8%) and 1-year mortality (25% vs. 15%) were higher among patients with COVID-19 and CIED.

Conclusions: Patients with COVID-19 and CIED had a significantly higher prevalence of co-morbidities that were associated with increased mortality. Although,CIED by itself was not found as an independent risk factor for morbidity and mortality, it may serve as a warning for severe illness with COVID-19.

Background: Due to the high variability in malignancy rate among cytologically indeterminate thyroid nodules (Bethesda categories III–V), the American Thyroid Association recommends that each center define its own categorical cancer risk.

Objectives: To assess cancer risk in patients with cytologically indeterminate thyroid nodules who were operated at our center.

Methods: In a retrospective study, we analyzed the pathology results of all the patients whose fine needle aspiration results showed Bethesda III–V cytology and who subsequently underwent total thyroidectomy or lobectomy from December 2013 to September 2017.

Results: We analyzed 56 patients with indeterminate cytology on fine needle aspiration. Twenty-nine (52%) were defined as Bethesda III, 19 (34%) Bethesda IV, and 8 (14%) Bethesda V category. Malignancy rates were 38%, 58%, and 100% for Bethesda categories III, IV, and V, respectively. Most malignancies in Bethesda categories III and IV were follicular in origin (follicular thyroid carcinoma and follicular type papillary thyroid carcinoma), while 100% of the patients with Bethesda category V were diagnosed with classical papillary thyroid carcinoma. No correlation was found between sonographic and cytological criteria of nodules with Bethesda categories III and IV and rates of malignancy.

Conclusions: We found higher than expected rates of malignancy in indeterminate cytology. This finding reinforces the guidelines of the American Thyroid Association to establish local malignancy rates for thyroid nodules with indetermined cytology.

Backgrounds: Behçet's disease (BD) is a chronic vasculitic multi-systemic disease of unknown etiology. BD is characterized by recurrent attacks of oral aphthae, genital ulcers, and uveitis. BD is a multisystemic disorder and as such it may provoke various psychiatric manifestations, including depression.

Objectives: To evaluate the association between BD and depression, adjusting for established risk factors for depression.

Methods: We executed a cross-sectional study based on the Clalit Health Services database, the largest healthcare organization in Israel, serving over 4.4 million members. For this study 873 BD patients were detected and matched with 4369 controls by age and sex.

Results: The rate of depression was higher among the BD patients compared with the control group (9.39% vs 5.49%, respectively, odds ratio [OR] 1.79, 95% confidence interval [95%CI] 1.37–2.31, P < 0.001). An association between BD and depression was also observed on multivariable analysis (OR 1.83, 95%CI 1.39–2.39, P < 0.001). When stratifying the data, according to established risk factors, the association between BD and depression was prominent in the youngest age group (18–39 years of age), low and high socioeconomical status, and non-smokers.

Conclusions: Establishing the association between BD and depression should influence the attitude and the treatment of BD patients, as this relationship requires a more holistic approach and a multidisciplinary treatment regimen for all patient needs.

Background: 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.

Methods: We compared medical encounters between different services provided by the IDF Medical Corps. We related them to specific time periods: pre-first lockdown, first lockdown (and corresponding timeframes of the previous 3 years), between lockdowns, second lockdown, and post-second lockdown.

Results: Compared to past periods, we found a similar reduction of 27–30% in primary care medical encounter rates during the two lockdowns: 42–43% in sick days and 50–54% in referrals to the emergency department. Referral rates to all specialist medical encounters and elective surgeries decreased significantly during the first lockdown period and increased 1.2–3.5 times during the second lockdown.

Conclusions: A continuance of the shift to telehealth is required to withstand a future lockdown, with a full supply of secondary medical services attuned to core medical issues relevant for combat personnel. A liberal sick leave policy is required to eliminate unnecessary in-person visits, thus reducing the risk of infection.
