Background: The prevalence of Group A streptococcus (GAS) carriage among adults is studied less than in children. The variability of reported carriage rates is considerably large and differs among diverse geographic areas and populations.

Objectives: To evaluate the prevalence of GAS carriage among adults in Israel.

Methods: In this prospective study, conducted in a large healthcare maintenance organization in Israel, we obtained pharyngeal cultures from adults attending the clinic without upper respiratory tract complaints or fever. Patient data included sex, age, number of children, and religious sectors.

Results: From May to December 2022, eight family physicians collected a total of 172 throat swabs (86% response rate). The median age was 37 years (range 18–65); 72.7% were females, 22.7% were ultra-Orthodox Jewish, and 69.2% had children. The prevalence of GAS carriage was 6.98%, 95% confidence interval (95%CI) 3.7%–11.9%. GAS carriers were younger (31.7 vs. 39.3 years, P = 0.046), and the majority were ultra-Orthodox Jews (58.3% vs. 20%, P = 0.006). All GAS carriers were from lower socioeconomic status. When assessing risk factors for GAS carriage using multivariate analysis, only being an ultra-Orthodox Jew was positively related to GAS carriage (adjusted odds ratio 5.6, 95%CI 1.67–18.8).

Conclusion: Being an ultra-Orthodox Jew was the single variable associated with a GAS carriage, which may be related to having many children at home and living in overcrowded areas. Primary care physicians in Israel should recognize this situation when examining patients with sore throats, mainly ultra-Orthodox Jews.

Background: Survivors of critical illness are at increased risk of long-term impairments, referred to as post-intensive care unit (ICU) syndrome (PICS). Post-traumatic stress disorder (PTSD) is common among ICU survivors with reported rates of up to 27%. The prevalence of PTSD among Israeli ICU survivors has not been reported to date.

Objectives: To evaluate the prevalence of new onset PTSD diagnosed in a post-ICU clinic at a tertiary center in Israel.

Methods: We conducted a retrospective, single center, cohort study. Data were collected from medical records of all patients who visited the Tel Aviv Sourasky Medical Center post-ICU clinic between October 2017 and June 2020. New onset PTSD was defined as PTSD diagnosed by a certified board psychiatrist during the post-ICU clinic visit. Data were analyzed using descriptive statistics.

Results: Overall, 39 patients (mean age 51 ± 17 years, 15/39 females [38%]) attended the post-ICU clinic during the study period. They were evaluated 82 ± 57 days after hospital discharge. After excluding 7 patients due to missing proper psychiatric analysis, 32 patients remained eligible for the primary analysis. New PTSD was diagnosed in one patient (3%).

Conclusions: We found lower incidence of PTSD in our cohort when compared to existing literature. Possible explanations include different diagnostic tools and low risk factors rate. Unique national, cultural, and/or religious perspectives might have contributed to the observed low PTSD rate. Further research in larger study populations is required to establish the prevalence of PTSD among Israeli ICU survivors.

Background: Completing internal medicine specialty training in Israel involves passing the Israel National Internal Medicine Exam (Shlav Aleph), a challenging multiple-choice test. multiple-choice test. Chat generative pre-trained transformer (ChatGPT) 3.5, a language model, is increasingly used for exam preparation.

Objectives: To assess the ability of ChatGPT 3.5 to pass the Israel National Internal Medicine Exam in Hebrew.

Methods: Using the 2023 Shlav Aleph exam questions, ChatGPT received prompts in Hebrew. Textual questions were analyzed after the appeal, comparing its answers to the official key.

Results: ChatGPT 3.5 correctly answered 36.6% of the 133 analyzed questions, with consistent performance across topics, except for challenges in nephrology and biostatistics.

Conclusions: While ChatGPT 3.5 has excelled in English medical exams, its performance in the Hebrew Shlav Aleph was suboptimal. Factors include limited training data in Hebrew, translation complexities, and unique language structures. Further investigation is essential for its effective adaptation to Hebrew medical exam preparation.

Background: Pregnant women are at higher risk for severe coronavirus disease 2019 (COVID-19). Since the release of the BNT162b2 messenger RNA vaccine (Pfizer/BioNTech), there has been accumulated data about the three vaccine doses. However, information regarding obstetric and neonatal outcomes of pregnant women vaccinated with the third (booster) vaccine is limited and primarily retrospective.

Objectives: To evaluate the obstetric and early neonatal outcomes of pregnant women vaccinated during pregnancy with the COVID-19 booster vaccine compared to pregnant women vaccinated only by the first two doses.

Methods: We conducted a cross-sectional study of pregnant women who received the BNT162b2 vaccine during pregnancy. Obstetric and neonatal outcomes were compared between pregnant women who received only the first two doses of the vaccine to those who also received the booster dose.

Results: Overall, 139 pregnant women were vaccinated during pregnancy with the first two doses of the vaccine and 84 with the third dose. The third dose group received the vaccine earlier during their pregnancy compared to the two doses group (21² vs. 31⁵ weeks, respectively, P < 0.001). No differences in obstetric and early neonatal outcomes between the groups were found except for lower rates of urgent cesarean delivery in the third dose group (adjusted odds ratio 0.21; 95% confidence interval 0.048–0.926, P = 0.039).

Conclusions: Compared to the first two doses of the BNT162b2 vaccine given in pregnancy, the booster vaccination is safe and not associated with an increased rate of adverse obstetric and early neonatal outcomes.

Background: Cases of second trimester pregnancy loss can be treated either pharmacologically or by surgical evacuation. Misoprostol, an E1-prostaglandin analog, is used to facilitate the evacuation of the uterus.

Objectives: To determine the risk factors associated with patients who were treated with five or more repeated doses of misoprostol.

Methods: We conducted a retrospective study of patients treated with vaginal misoprostol at our institution between December 2016 and October 2021 for second trimester pregnancy loss.

Results: In total, 114 patients were eligible for analysis; 83 were treated with < 5 doses and 31 with ≥ 5. We recorded each case in which repeated doses were administered, irrespective of predetermined conditions such as gravidity, parity, maternal age, or gestational age. Moreover, cases of five or more misoprostol dosing were not associated with an increased complications rate, except for the increased duration of hospitalization (3.1 vs. 2.2 days, P-value < 0.01).

Conclusions: Repeated dosing could not be predicted before treatment among those treated with vaginally administered misoprostol for second trimester pregnancy loss. However, low complication rates of repeated dosing may reassure both physicians and patients regarding safety, efficacy, and future fertility.

Anti-tumor necrosis factor-alpha (anti-TNFα) medications are the most frequently used biologicals to treat inflammatory bowel disease (IBD). Little is known about the ocular side effects of this drug category. We present a case series of six young patients with Crohn disease (CD) and no previous ophthalmologic manifestations who developed blepharitis after commencing treatment with anti-TNFα therapy. Six otherwise healthy patients with CD, with no history of allergies or prior ocular complaints, developed blepharitis at a median of 7.5 months after the initiation of anti-TNFα therapy. All ophthalmic findings were treated topically. The ocular symptoms of two of the patients resolved shortly after discontinuation of the anti-TNFα treatment. The other four presented with relapsing-remitting symptoms. Blepharitis is a common ocular disease in the general population and an extra-intestinal manifestation in patients with IBD. It may be an adverse effect of anti-TNFα therapy in this patient population.

Background: Little is known about phenotypical variations among ethnic groups in patients with Parkinson's disease (PD) in Israel. Clinical characteristics of non-Ashkenazi Jews (NAJ) are scantly described.

Objectives: To describe clinical aspects of PD in ethnic groups in Israel, focusing on NAJ and Ashkenazi Jews (AJ).

Methods: In this cross-sectional retrospective study, we collected demographic, genetic, and clinical characteristics of patients from different ethnic Jewish backgrounds. Ethnic groups included AJ; North African Jews (NAFJ); oriental Jews (OJ) originating from Iran, Iraq, and Buchara; Balkan Jews; Yemenite Jews (YJ); and Jews of mixed origin. Clinical characteristics included hyposmia, urinary complaints, constipation, and rapid eye movement sleep behavioral disorder. Cognitive complaints, motor features, levodopa-induced dyskinesia, and motor fluctuations were collected. Motor part of the MDS-UPDRS and Hoehn and Yahr scores were collected.

Results: The study comprised 174 PD Jewish patients (63.2% AJ, 56.4% males). The age at onset was 65.3 ± 10.2 years; 106 patients (60.9%) were genotyped (17 glucocerebrosidase [16.0%], 13 leucine-rich repeat kinase 2 [LRRK2] [12.3%]). Rates of hyposmia were significantly higher in AJ than NAJ (56.6% vs. 39.5%, respectively, P = 0.003). No significant differences were found in motor features in all variables. Of 13 AJ patients carrying the LRRK2 mutation, only one had hyposmia. Three patients with LRRK2 were NAJ.

Conclusions: Hyposmia is less prevalent in PD patients of NAJ origin than in AJ. The rate of hyposmia in NAFJ patients is particularly low. The rate of other non-motor features is similar between NAJ and AJ patients.

Background: Group A Streptococcus (GAS), the predominant bacterial pathogen of pharyngitis, is sometimes difficult to distinguish clinically from viral pharyngitis. Despite the high prevalence of viral pharyngitis in children, antibiotic treatment is common.

Objective: To investigate the effectiveness of an antibiotic stewardship program (ASP) on antibiotic prescription in children with GAS pharyngitis (GAS-P) at a large pediatric community clinic.

Methods: Antibiotic prescription data were collected from October 2016 to March 2017 (pre-intervention period) and from October 2017 to March 2018 (post-intervention period). The intervention was a one-day seminar for primary care pediatricians on the diagnosis and treatment of GAS-P in children according to national guidelines.

Results: The overall prevalence of testing differed between the two time periods. There was a decrease in children who did not undergo any testing (from 68% to 63%), an increase in streptococcal rapid antigen detection testing (28% to 32%), and a slight increase in throat cultures (3% to 4%) (p = 0.02). There was no change in the types of antibiotics prescribed before and after the intervention (p = 0.152).

Conclusions: The ASP resulted in a slight reduction in the percentage of children who did not undergo laboratory testing for GAS-P and a slight reduction in the percentage of children who received antibiotic treatment. The ASP did not reduce the use of broad-spectrum antibiotics and macrolides.

Background: Abdominal pathology in pregnant patients is a frequent challenge for emergency department physicians. Ultrasound is the imaging modality of choice but is inconclusive in approximately one-third of cases. Magnetic resonance imaging (MRI) is becoming increasingly available, even in acute settings. Multiple studies have defined the sensitivity and specificity of MRI in this population.

Objectives: To evaluate the use of MRI findings in pregnant patients presenting with acute abdominal complaints to the emergency department.

Methods: This retrospective cohort study was conducted at a single institution. Data were collected on pregnant patients who underwent an MRI for acute abdominal complaints between 2010 and 2019 at a university center. Patient demographics, diagnosis at admission, ultrasound and MRI findings, and discharge diagnosis were recorded and evaluated.

Results: In total, 203 pregnant patients underwent an MRI for acute abdominal complaints during the study period. MRI was found without pathology in 138 cases (68%). In 65 cases (32%), the MRI showed findings that could explain the patient's clinical presentation. Patients presenting with long-standing abdominal pain (> 24 hours), fever, leukocytosis, or elevated C-reactive protein values were at a significantly increased risk of having an acute pathology. In 46 patients (22.6%), MRI findings changed the primary diagnosis and management while in 45 patients (22.1%) MRI findings improved characterization of the suspected pathology.

Conclusions: MRI is helpful when clinical and sonographic findings are inconclusive, leading to changes in patient management in more than one-fifth of patients.

Background: A limited program for kidney donation from uncontrolled donation after cardiocirculatory determination of death (uDCDD) was implemented at four hospitals in Israel in close cooperation with Magen David Adom (MDA), the national emergency medical service.

Objectives: To assess the outcome of transplantations performed between January 2017 and June 2022.

Methods: Donor data included age, sex, and cause of death. Recipient data included age, sex, and yearly serum creatinine levels. A retrospective study of out-of-hospital cardiac arrest cases treated by MDA during 2021 were analyzed to assess their compatibility as potential uDCDD donors.

Results: In total, 49 potential donors were referred to hospitals by MDA. Consent was obtained in 40 cases (83%), organ retrieval was performed in 28 cases, and 40 kidneys were transplanted from 21 donors (75% retrieval rate). At 1-year follow-up, 36 recipients had a functioning graft (4 returned to dialysis) and mean serum creatinine 1.59 ± 0.92 mg% (90% graft survival). Outcome after transplantation showed serum creatinine levels (mg%) at 2 years 1.41 ± 0.83, n=26; 3 years 1.48 ± 0.99, n=16; 4 years 1.07 ± 1.06, n=7; and 5 years 1.12 ± 0.31, n=5. One patient died of multiple myeloma at 3 years. The MDA audit revealed an unutilized pool of 125 potential cases, 90 of whom were transported to hospitals and 35 were declared dead at the scene.

Conclusions: Transplant outcomes were encouraging, suggesting that more intensive implementation of the program may increase the number of kidneys transplanted, thus shortening recipient waiting lists.

An 11-year-old female presented with encephalomyelitis in the presence of anti-myelin oligodendrocytes glycoprotein (MOG) antibodies (Abs), suspected to be triggered by concurrent respiratory adenovirus infection. The prognosis of such cases depends on prompt treatment; therefore, early diagnosis is crucial.

Sulfonylureas have been used to treat patients with diabetes for the last 80 years. The main side effect of this drug class is hypoglycemia, which might be severe and protracted. With the emergence of new medications with improved safety and better efficacy in preventing diabetes complications and cardiovascular morbidity and mortality, the use of these agents is waning.

Sulfonylureas are historically classified into two generations. The generation first includes drugs such as tolbutamide and chlorpropamide, which are no longer used. The second generation includes glibenclamide and glimepiride, which have different pharmacokinetic properties and active metabolites.

In this case report, we present a patient with diabetes and end-stage renal disease (ESRD) who developed prolonged hypoglycemia following the unauthorized use of a food supplement containing the first-generation sulfonylurea - tolbutamide.

In September 2020, a 37-year-old man without significant medical history or medication use presented to the emergency department with shortness of breath. The patient denied any history of shortness of breath, travel history, recent sick contacts, or history of lung disease. On arrival, the patient was afebrile with a respiratory rate of 26 breaths per minute (b/m), oxygen saturation 82% on ambient air, blood pressure 130\80 mmHg, and heart rate 130 beats per minute (bpm). He was started on three liters per minute oxygen therapy, which improved his saturation to 90%. Physical examination was remarkable for tachypnea and diffuse bilateral inspiratory lung crackles. Electrocardiogram revealed sinus tachycardia.

Background: Epidemiological studies have shown a connection between ethnic origin and the incidence and outcome of systemic lupus erythematosus (SLE).

Objective: To evaluate the SLE outcomes among Ashkenazi Jews, non-Ashkenazi Jews, and Arabs.

Methods: We conducted a retrospective study of patients who were diagnosed with SLE and followed in lupus clinics at two large tertiary medical centers. The data were obtained from patient medical records. Patients were stratified into three ethnic origins: Ashkenazi Jews, non-Ashkenazi Jews, and Arabs. The primary outcomes were all-cause mortality, development of end-stage kidney disease (ESKD), and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) 2K ≤ 4 at last visit.

Results: We included 570 patients in this study. The Arab group showed the highest number of SLE classification criteria at diagnosis and last encounters compared to non-Ashkenazi and Ashkenazi Jewish groups (6.0 vs. 5.0 and 4.0, respectively at diagnosis, P < 0.001; 8.0 vs. 7.0 and 6.0 at last visit, P = 0.01). In multivariate models, Arab patients had three times higher risk of all-cause mortality than Ashkenazi Jews (hazard ratio 2.99, 95% confidence interval [95%CI] 1.32–6.76, P = 0.009). ESKD was similar among the study groups. Low disease activity (SLEDAI 2K ≤ 4) at last visit was lower in the Arab group than the Ashkenazi Jews (odds ratio 0.50, 95%CI 0.28–0.87, P = 0.016), depicting a medium-to-high disease activity among the former.

Conclusions: Physicians should consider the influence of the ethnicity of the SLE patient when deciding on their care plan.

Background: Clinical investigations of long-term effects of coronavirus disease 2019 (COVID-19) are rarely translated to objective findings.

Objectives: To assess the functional capacity of individuals reported on deconditioning that hampered their return to their pre-COVID routine.

Methods: Assessment included the 6-minute walk test (6MWT) and the 30-second sit-to-stand test (30-STST). We compared the expected and observed scores using the Wilcoxon signed-rank test. Predictors of test scores were identified using linear regression models.

Results: We included 49 individuals, of whom 38 (77.6%) were recovering from mild COVID-19. Twenty-seven (55.1%) individuals had a 6MWT score lower than 80% of expected. The average 6MWT scores were 129.5 ± 121.2 meters and 12.2 ± 5.0 repeats lower than expected scores, respectively (P < 0.001 for both). The 6MWT score was 107.3 meters lower for individuals with severe COVID-19 (P = 0.013) and rose by 2.7 meters per each 1% increase in the diffusing capacity of carbon monoxide (P = 0.007). The 30-STST score was 3.0 repeats lower for individuals who reported moderate to severe myalgia (P = 0.038).

Conclusions: Individuals with long COVID who report on deconditioning exhibit significantly decreased physical capacity, even following mild acute illness. Risk factors include severe COVID-19 and impaired diffusing capacity or myalgia during recovery.
