Background: Significant mitral regurgitation (MR) is associated with less spontaneous echo contrast but its effect on the occurrence of ischemic stroke in patients with atrial fibrillation (AF) is unknown.

Objectives: To examine the association of MR grade and the risk of ischemic stroke (IS) in AF patients with heart failure (HF).

Methods: We investigated 2748 patients with known AF who were hospitalized due to acute decompensated HF. All patients underwent echocardiography during hospitalization. Patients were divided into groups based on the degree of MR (high-grade MR [3–4] vs. no/low-grade MR [0–2]). The primary endpoint was IS during long term follow-up.

Results: Mean age was 79 ± 11 years, 48% were women. After 2 years of follow-up, the cumulative incidence of IS among patients with high-grade MR was significantly lower compared to patients with no/low-grade MR (6% vs. 12%, respectively; P-value = 0.0064). Multivariate Fine and Gray analysis, adjusting for CHA₂DS₂-VASc, and accounting for the competing risk of death and valve intervention, showed the presence of high-grade MR was associated with a significant 50% (P = 0.013) reduction in the risk of IS compared with no/low-grade MR. When added to the CHA₂DS₂-VASc score, MR grade allowed more accurate prediction of IS with an overall improvement of 12% (95% confidence interval 5–17%) using net reclassification index analysis.

Conclusions: Our findings suggest an inverse correlation between MR grade and the risk of stroke among AF patients with HF. These findings may be used for improved risk assessment in this population.

Background: Out-of-hospital cardiac arrest (OHCA) poses a considerable health burden and offers poor prognosis. Information about OHCA in Israel is scarce.

Objectives: To present a pilot registry of prehospital and in-hospital characteristics of patients with OHCA.

Methods: A descriptive study was conducted of consecutive adult patients with OHCA treated in the field by Magen David Adom (MDA) paramedics and treated at the Sheba Medical Center.

Results: The study included 99 patients with OHCA who were brought by MDA to the Sheba Medical Center. The median age was 79 years (IQR 67–89(, 61% were male. In total, 69% of the events occurred at home, 16% at nursing facilities, 10% on streets, and 2% in public buildings. Most events (80%) were witnessed. Bystander-basic life support (BLS) was administered to 28%, 45% received BLS from an emergency medical service first responder. Automated external defibrillation was used in 40% of cases. In our cohort, 51 patients (51%) survived initial treatment in the emergency department (ED) and were hospitalized. Electrocardiography at arrival demonstrated ST-elevation in 22% of cases. Coronary angiography was performed in 19% (n=19) of patients, and 12% (n=12) underwent percutaneous intervention. Eventually, 26 patients (26%) survived to discharge with a Cerebral performance categories were as follows: 13% (n=13) with good cerebral performance, 10% (n=10) with moderate disability, and 3% (n=3) with severe disability or unconscious.

Conclusions: Among those admitted after surviving ED resuscitation, half survived to discharge. Most of those who survived hospitalization and were discharged with good neurological performance were young males.

Immune thrombocytopenia (ITP), driven by autoantibodies targeting platelet antigens, is an acquired disorder posing considerable challenges, particularly in pregnancy, where its prevalence escalates to 13 per 10,000 women, a tenfold increase compared to the general population [1]. Predominantly characterized by a heightened risk of bleeding, particularly during pregnancy, the incidence of significant hemorrhagic events stands at approximately 18%, mostly non-severe [1]. Despite its rarity, thrombosis can manifest as a complication, especially when accompanied by antiphospholipid antibodies, which amplify the propensity for arterial and venous thrombotic events alongside obstetric complications and thrombocytopenia [2,3].

In this case report, we present the case of a young female with primary unexplained infertility, complicated by ITP and antiphospholipid syndrome (APS), predisposing her to increased bleeding and thrombotic risks. During a multidisciplinary consultation, the medical staff navigated the intricate landscape of fertility treatments and pregnancy options, carefully considering the delicate balance between risks and benefits to optimize patient outcomes.

Background: In times of war, healthcare systems face the dual challenge of attending to the medical needs of injured soldiers and civilians as well as struggling to meet the everyday healthcare demands of civilians.

Objectives: To assess the correlation between exposure to war and the likelihood of spontaneous abortion (SAB) and to compare it to a similar period in previous years.

Methods: We conducted a retrospective study comparing the rate of SAB during war to the previous years.

Results: During the Iron Swords war, 381 patients out of 3245 (11.74%) were diagnosed with SAB, compared to 530 of 4080 (13%) in 2022, 536 of 3387 (13.8%) in 2021, and 516 of 3798 (13.6%) in 2020. The median gestational age at diagnosis was similar between the groups, with most cases identified during the first trimester. The study group exhibited a significantly higher prevalence of smoking (18.47% vs. 7.75% vs. 6.3% vs. 9.3%, P = 0.03), with no differences in the prevalence of chronic diseases and in the method of pregnancy termination.

Conclusions: Exposure to stress due to war during early pregnancy appears to have no significant impact on the rate of SAB.

In this case report, we elucidated the complex etiology of new-onset ascites through the unusual presentation of a 32-year-old female with abdominal swelling, oliguria, and acute renal failure. This patient's ascites was attributed to urinary bladder rupture, a rare but critical consideration in differential diagnoses. Highlighting the significance of this case, bladder rupture without recent trauma history, especially post-gynecological surgery, poses a diagnostic challenge due to its rarity and potential for severe morbidity and mortality if not promptly recognized and managed. Our patient's journey, from initial symptoms to the eventual discovery of bladder rupture, underscores the necessity of considering this diagnosis in similar clinical scenarios. The case uniquely demonstrates pseudo-renal failure, a phenomenon resulting from reversed dialysis across the peritoneal membrane, which further complicated the diagnostic process.

Background: Data regarding the management of adnexal torsion (AT) during the coronavirus disease 2019 (COVID-19) pandemic are scarce.

Objectives: To study the effects of actions to limit the spread of COVID-19 on AT management.

Methods: We conducted a retrospective cohort study of all women who underwent laparoscopy for suspected AT between March 2011 and February 2021. We compared the COVID-19 pandemic period, (15 March 2020–2 August 2021, group A) to a parallel period (2019–2020, group B), and a 9-year period preceding the pandemic (March 2011–February 2020, group C).

Results: We performed 97 laparoscopies in group A, 82 in group B, and 635 in group C. The proportion of women presenting following in vitro fertilization treatment was lower (odds ratio [OR] 0.22, 95% confidence interval ]95%CI] (0.06–0.86), P < 0.023). Time from admission to decision to operate was shorter (2.7 vs. 3.9 hours, P = 0.028) in group A than group B. Time from admission to surgery was shorter (9.1 vs. 12.5 hours, P = 0.005) and the rate of surgically confirmed AT was lower (59 [60.8%] vs. 455 [71.7%], P = 0.030, OR 0.61, 95%CI 0.39–0.95) in group A than group C. Among surgically confirmed AT cases only, mean time from admission to decision was shorter in group A than group B (2.6 vs. 4.6 hours, P = 0.014).

Conclusions: We identified differences in time from admission to clinical decision and from admission to surgery among women with suspected AT during the COVID-19 pandemic.

Long-term sperm preservation plays a pivotal role in providing a lifeline for individuals grappling with medical and fertility challenges; thus, enabling them to pursue their aspirations of parenthood. While the significance of frozen sperm is unquestionable, it is vital to address the persistently low utilization and disposal rates of stored samples over time and resulting in an unintended accumulation of unclaimed doses. This accumulation not only carries significant medical, legal, and financial burdens for the institutions responsible, such as sperm banks, but also raises complex ethical considerations, particularly concerning potential biological paternity. These multifaceted considerations are particularly relevant within Israel's publicly funded healthcare system, accentuating the need for clearly defined preservation criteria in cases where an immediate clinical necessity is not readily apparent. We highlight the important clinical, ethical, and economic aspects of preserving the potential for biological paternity and efficiently managing the resources and responsibilities associated with long-term sperm preservation.

Hiatal hernia is defined as a protrusion of abdominal contents through the hiatal foramen into the thoracic cavity. Etiology is presumed to be a congenital malformation, trauma, or iatrogenic like prior surgical dissection of the hiatus during surgery for esophageal or gastric etiology. Age, sex, hormonal changes, body habitus (i.e., kyphosis, scoliosis), and increased body weight are key risk factors. Most hiatal hernias are asymptomatic and discovered incidentally. Surgical repair of hiatal hernia is indicated in symptomatic patients with dysphagia, weight loss, respiratory symptoms such as aspirations, and recurrent pneumonia events [1]. Complications arising from laparoscopic repair of hiatal hernia are generally minor and do not typically necessitate surgical intervention. Major complications include pneumothorax, splenic laceration, esophageal rupture, and pericardial injury. Other complications include recurrence of hernia, vagal nerve injury, gastroesophageal reflux disease, and gastroparesis. The utilization of mesh in repair procedures introduces additional complications such as mesh migration and mesh infection. Previously reported recurrence rates following the repair of a hiatal hernia with mesh range from 10–30%. In this case communications, we presented a case involving the early recognition and treatment of postoperative cardiac tamponade.

Background: The use of proprotein convertase subtilisin/kexin type 9 monoclonal antibodies (PCSK9 mAbs) is emerging for lowering low-density lipoprotein cholesterol (LDL-C). However, real-world data is lacking for their use among elderly patients.

Objective: To define the characteristics of elderly patients treated with PCSK9 mAbs and to evaluate the efficacy and tolerability compared with younger patients.

Methods: We conducted a retrospective cohort study of elderly patients (≥ 75 years at enrollment) treated with PCSK9 mAbs for primary and secondary cardiovascular prevention. Data were retrieved for demographic and clinical characteristics; indications for treatment; agents and dosages; concomitant lipid lowering treatment; LDL-C levels at baseline, 6, 12 months, and at the end of follow up. Data also included achieving LDL-C target levels and adverse effects.

Results: The cohort included 91 elderly patients and 92 younger patients, mean age 75.2 ± 3.76 and 58.9 ± 7.4 years (P < 0.0001). Most patients (82%, 80%) were in high/very high-risk categories. For almost all (98%, 99%), the indication was statin intolerance, with PCSK9 mAb monotherapy the most prevalent regimen. The average follow-up was 38.1 ± 20.5 and 30.9 ± 15.8 months (P = 0.0258). Within 6 months the LDL-C levels were reduced by 57% in the elderly group and by 59% in the control group (P = 0.2371). Only 53% and 57% reached their LDL-C target levels. No clinically significant side effects were documented.

Conclusion: PCSK9 mAbs have similar effects and are well tolerated among elderly patients as in younger patients.

Background: Sperm banks initially focused on providing sperm donation (SD) to heterosexual couples grappling with severe male infertility. Notable advancements in fertility treatments and sociological trends have broadened the scope of SD toward single women and same sex female couples.

Objectives: To evaluate SD recipient characteristics over the last three decades in Israel according to demographic parameters.

Methods: This retrospective cohort study included 5489 women who received SD between January 1992 and December 2021 from a tertiary referral center. We divided the overall period into six groups of five years each. A comparison of demographic characteristics of women who received SD in different periods was performed according to age at the beginning of the treatment, marital status (single women and same sex female couples, heterosexual couples), and ethnic origin.

Results: The average age of women who received SD was 37.02 ± 5.36 years. The average patient age rose from 35.08 years in 1992–1997 to 37.43 years in 2017–2021 (P-value < 0.01). The use of SD was more common among single women and same sex female couples compared to heterosexual couples in later years. Regarding single and same sex female couple, the percentage of SD recipients increased radically from 33% to 88.1% (P-value < 0.01).

Conclusions: Modern sperm banks treat older patients in non-heterosexual relationships. These trends encompass not only medical implications (e.g., in vitro fertilization vs. intrauterine insemination) but also delve into the personal and sociological impact experienced by both patients and offspring.

A 42-year-old healthy man collapsed suddenly in the street while walking. The patient received 2 minutes of basic life support until an automatic external defibrillator was brought and detected ventricular fibrillation (VF), which was successfully terminated by a single shock. The patient regained consciousness and was transferred to the hospital.

The patient’s physical examination was normal with no neurologic deficit. Blood pressure was 147/102 mmHg. Brain computed tomography showed normal findings. The first troponin I measurement within 1 hour of the event was in the normal range (19.6 ng/L, normal < 20 ng/L) and rose to 99.9 ng/L after 3 hours.

Background: In 2019, 1 mg subcutaneous semaglutide was registered for the treatment of diabetes in Israel. Recognition of its effect on weight has led to its use as a treatment for obesity.

Objectives: To explore physicians’ pre-therapy considerations, therapy practices, and attitudes regarding subcutaneous semaglutide for weight loss.

Methods: A 22-item questionnaire was disseminated to physicians who prescribed semaglutide 1-mg for weight loss using an authorized off-label path.

Results: In total, 127 physicians completed the questionnaire. As for pretreatment requirements, in the absence of diabetes, 30% requested a minimal body mass index of 30 kg/m2. Additional requirements were documented lifestyle-change effort (67%) and prior weight loss medication use (13%). Half of the physicians regarded calorie restriction, and 23% considered physical activity as necessary for weight loss while on therapy. As for dose, most physicians (78%) started with a 0.25-mg weekly injection, 57% doubled the dose monthly, and all others recommended doubling when side effects subsided. Regarding weight loss goal, 43% of the physicians set a personal goal with each patient while 26% limited the goal to 10% of initial weight. Fewer than 50% of physicians discussed treatment duration with their patients, and 52% of patients discontinued therapy in the first 3 months. The main reasons for discontinuation were price, lack of effect, and fear of long-term side effects.

Conclusions: The diverse approaches regarding off-label use of semaglutide for weight reduction highlight the necessity to guide physicians and standardize treatment regimen.

Acute or chronic aortic dissection is considered a rare emergency, with an estimated rate of 2.9 to 5 cases per 100,000 patients each year. This condition is most prevalent in males older than 65 years of age with a history of hypertension, atherosclerosis, and previous cardiac surgery [1,2]. To confirm the diagnosis, imaging is used, often by computed tomography angiography (CTA) of the chest. Although prompt treatment is required, patients often present with non-specific symptoms, such as abdominal pain or neurologic deficits, resulting in the early diagnosis of less than 20% and a high mortality rate [1].

Intravesicular administration of Bacillus Calmette–Guérin (BCG), a live attenuated strain of Mycobacterium bovis, has long been used as adjuvant therapy for treatment of non-muscle invasive bladder carcinoma. BCG is usually well tolerated; however, infectious complications can range from 1–5% of cases. Infectious complications of BCG [1] can be divided into localized disease, which is considered a late onset disease occurring 3 months following treatment such as cystitis, Epididymo-orchitis, and pyelonephritis. Another form is a systemic disease, which is an early onset manifestation including sepsis syndrome that usually occurs directly after treatment and is the most common form of disseminated BCG infection.

Background: 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.

Methods: We conducted a retrospective cohort study to compare prehospital and in-hospital data regarding ET in the emergency department (ED) versus the operating room (OR).

Results: Between 2009 and 2017, 6532 casualties presented to the ED; 1125 with trauma to the chest. Fifty-four of those with chest trauma underwent ET in the hospital (4.8%), 22 (41%) in the ED, and 32 (59%) in the OR. The overall mortality of the ET subgroup was 48%. With regard to thoracotomies, 19/22 of patients (86%) who underwent ET in the ED died compared to 2/28 in the OR (13%).

Conclusions: Utilizing ET after chest trauma with appropriate clinical indications, well-trained personnel, and prompt transportation poses a significant challenge, but may be associated with better survival than that reported previously with military casualties. Adoption of indications and timed allocation to the OR may improve outcomes with chest trauma casualties.
