Background: The Agatston coronary artery calcium (CAC) score is a decision-guiding aid for risk assessment and personalized management in the primary prevention of atherosclerotic cardiovascular disease.

Objectives: To explore the real-life clinical experience of CAC testing by characterizing its indications, significance of scores, and corresponding lipid-lowering treatments.

Methods: A retrospective descriptive study of patients treated at the lipids clinic at Rabin Medical Center (Beilinson Campus), who underwent CAC score evaluation between 2017 and 2022 was conducted. The data collected from electronic medical files included demographics, co-morbidities, indications for the test, CAC score levels, and the recommended therapeutic regimen.

Results: The study cohort included 88 patients. The main indication was assessment of the existence of atherosclerosis in cases where there was no clear indication for lipid lowering treatment (65, 74%). In most patients, there was no evidence of atherosclerosis (CAC = 0 AU, n=30) or only mild disease (CAC=1–99 AU, n=35). As the CAC score increased, more patients were prescribed lipid lowering treatments, from very few prescriptions in those with a CAC score of 0 AU and almost 100% among those with score of ≥ 400 AU. The factors that predicted CAC > 0 AU were male sex and older age.

Conclusions: CAC scores should be used more often to determine risk assessment. Further analysis of the implications of scores between 0–400 AU is needed.

Background: Patients with mechanical prosthetic heart valves must be treated with vitamin K antagonists (VKA) due to an increased risk of valve thrombosis and systemic embolism.

Objectives: To assess the effects of the COVID-19 pandemic on VKA treatment control in patients with mechanical prosthetic heart valves.

Methods: We conducted a retrospective nationwide cohort study using the Clalit Health Services database. The cohort included patients who underwent either aortic or mitral valve replacement using a prosthetic mechanical valve. The primary outcomes included the overall time in therapeutic range (TTR) and the percent of patients with a TTR < 50% during the first year of the COVID-19 pandemic compared to preceding year.

Results: The cohort included 2381 patients. The percentage of patients who had at least two international normalized ratio (INR) tests during the first year of the COVID-19 pandemic was significantly lower compared to the year preceding the pandemic (81% and 87%, respectively, P < 0.001). In both years, the percentage of patients without any documented INR test was high (31.5% in the first COVID-19 pandemic year and 28.9% in the preceding year, P < 0.001). TTR was significantly lower during the 1st year of the COVID-19 pandemic compared to the preceding year (68.1% ± 26 and 69.4% ± 24, P = 0.03). A TTR > 50% was demonstrated in 78% and 81% during the pandemic and the preceding year, P = 0.009.

Conclusions: We noted overall poor VKA control in patients with mechanical heart valves. During the COVID-19 pandemic, VKA control became even worse as reflected by significantly lower TTR and INR tests rates.

Background: Coronary heart disease (CHD) patients are considered high cardiovascular risks. Guidelines recommend low-density lipoprotein cholesterol (LDL-C) target levels below 55 mg/dl with > 50% reduction from baselines. These levels can be reached by a combination of statins, ezetimibe, and anti-protein convertase subtilisin/kexin type 9 (anti-PCSK9) agents. Our clinical impression was that CHD patients do not reach LDL-C target levels, despite the wide availability.

Objectives: To evaluate whether hospitalization would result in changes in lipid lowering regimens and short-term compliance.

Methods: We conducted a retrospective cohort study using data of CHD patients who were admitted to internal medicine wards at Clalit Health Services medical centers because of anginal syndrome during 2020–2022. The data were evaluated for demographic and clinical characteristics; LDL-C level at admission, 6 months previously, and 3 months and 6–9 months after discharge; rates of reaching LDL-C target levels; and lipid lowering treatment at admission, discharge, and 6–9 months after.

Results: The cohort included 10,540 patients. One-third and three-quarters did not have lipids level measurements up to 6 months before and during hospitalization, respectively. Only one-fifth of the patients reached LDL-C values before and during admission (median LDL-C 72 mg/dl; range 53–101). Approximately half were treated with high-dose potent statins. Only 10% were treated with ezetimibe. Hospitalization did not have a clinically significant effect on short-term lipid lowering treatment or LDL-C levels.

Conclusions: Gaps were noted between guidelines and clinical practice for reaching LDL-C target levels. Further education and strict policy are needed.

War is a chaotic situation for most of the public sectors in the countries involved. These sectors also include the medical systems, especially medical education, of which medical communication is often neglected or forgotten due to objective and subjective causes on either side of the involved countries. By planning lessons on various aspects of medicine for countries at war and close mentoring and utilization of modern communications technologies, these difficulties can be minimized without jeopardizing the quality of medical studies nor medical communication. In this perspective article, we describe the objective and subjective measures taken by our team to achieve these goals during the Iron Swords war in our region.

Background: Fetal weight estimation at term is a challenging clinical task.

Objectives: To evaluate the association between peripheral white blood cell (WBC) count of the laboring women and neonatal birth weight (BW) for term uncomplicated pregnancies.

Methods: We conducted a single-center, retrospective cohort study (2006–2021) of women admitted in the first stage of labor or planned cesarean delivery. Complete blood counts were collected at admission. BW groups were categorized by weight (grams): < 2500 (group A), 2500–3499 (group B), 3500–4000 (group C), and > 4000 (group D). Two study periods were used to evaluate the association between WBC count and neonatal BW.

Results: There were a total of 98,632 deliveries. The dataset analyses showed a lower WBC count that was significantly and linearly associated with a higher BW; P for trend < 0.001 for women in labor. The most significant association was noted for the > 4000-gram newborns; adjusted odds ratio 0.97, 95% confidence interval 0.96–0.98; P < 0.001; adjusted for hemoglobin level, gestational age, and fetal sex. The 2018–2021 dataset analyses revealed WBC as an independent predictor of macrosomia with a significant incremental predictive value (P < 0.0001). The negative predictive value of the WBC count for macrosomia was significantly high, 93.85% for a threshold of WBC < 10.25 × 10³/µl.

Conclusions: WBC count should be considered to support the in-labor fetal weight estimation, especially valuable for the macrosomic fetus.

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.

Background: Cesarean deliveries (CD) are commonly performed using neuraxial anesthesia. The use of neuraxial morphine has proven beneficial in terms of postoperative pain management; however, its effect on postoperative urine retention remains unclear.

Objectives: To determine whether morphine injection into the neuraxis during CD influences postoperative urinary retention rate.

Methods: We conducted a retrospective case-control observational study of patients undergoing CD. We compared patients using morphine injected into the intrathecal or epidural spaces (November 2020 to October 2021) to a historical cohort of patients undergoing CD without morphine (November 2019 to October 2020). The primary outcome was the rate of postoperative overt urinary retention necessitating bladder catheterization.

Results: The study group comprised 283 patients, and 313 patients in the control group were eligible for analysis. No differences were found with respect to the baseline demographic and indication for CD. The number of postpartum urinary bladder catheterizations due to urine retention was higher in the study group (5% vs. 1%, P-value = 0.003). No cases of 30-day readmission were recorded. Moreover, patients treated with neuraxial morphine required fewer repeat doses of postoperative anesthesia (oral analgesia 7.4 vs. 10.1, intravenous analgesia 0.29 vs. 0.31, oral opioids 0.06 vs. 3.70, intravenous opioids 0.01 vs. 0.45, P-value < 0.001 for all)

Conclusions: While neuraxial morphine used during CD appears to be safe and effective, the risk of postoperative urinary retention seems to be increased due to its use. Cases of overt urinary retention treated by bladder catheterization does not lead to short-term complications.

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.

One of the most wonderful things in the practice of medicine is the endless opportunities to learn new things and encounter novel medical conditions and their manifestations. However, not all new experiences are necessarily welcomed. As we recently discovered, there are some medical encounters that no physician should ever face, because no patient should have to endure these encounters. That is, no person, and certainly no child, should ever go through the kind of cruel captivity we recently encountered following the horrific events of 7 October 2023 in Israel.

The issue of genital ulcers (GUs) in Israeli Arab female patients with Behçet's disease (BD is important as GUs are considered a unique feature of BD and stand as diagnostic criterion for the diagnosis in the International Study Group (ISG) criteria [1] and the International Criteria for Behcet Disease (ICBD) [2]. According to the ISG, GUs can be detected by a physician or by the patient [1]. While oral ulcers are easily observable, the identification of more hidden GUs pose a significant challenge.

Among patients admitted with acute decompensated heart failure (ADHF), deterioration of renal function with resulting acute kidney injury (AKI) is reported in up to 70% of patients with cardiogenic shock. Twenty percent of heart failure patients with AKI progress to dialysis (AKI-D). Optimal timing for initiation of renal replacement therapies (RRT) has been researched; however, minimal studies discuss guidelines for weaning from RRT [1]. Electronic monitoring of urine output (UO) may serve as a tool to aid in withdrawal from RRT. We present a case of ADHF with severe AKI requiring continuous renal replacement therapy (CRRT) where real-time electronic monitoring of UO was implemented for the first time to guide de-escalation therapy from CRRT until successful withdrawal.

Background: Ankylosing spondylitis (AS) and inflammatory bowel disease (IBD) are chronic conditions with overlapping pathogenic mechanisms. The genetic predisposition and inflammatory pathways common to both diseases suggest a syndemic relationship. While some evidence points to a connection between the two conditions, other reports do not support this link.

Objectives: To investigate the association between AS and the subsequent incidence of IBD. To identify potential risk factors and effect modifiers that contribute to this relationship.

Methods: Utilizing the Chronic Disease Registry of Clalit Health Services, we conducted a retrospective cohort study of individuals diagnosed with AS between January 2002 and December 2018. We compared these patients with age- and sex-matched controls, excluding those with a prior diagnosis of IBD. Statistical analyses included chi-square and t-tests for demographic comparisons, and Cox proportional hazards models for evaluating the risk of IBD development, with adjustments for various co-morbidities and demographic factors.

Results: The study included 5825 AS patients and 28,356 controls. AS patients demonstrated a significantly higher incidence of IBD with hazard ratios of 6.09 for Crohn's disease and 2.31 for ulcerative colitis, after multivariate adjustment. The overall incidence of IBD in the AS cohort was significantly higher compared to controls.

Conclusions: AS patients exhibit a markedly increased risk of developing IBD. These findings advocate for heightened clinical vigilance for IBD symptoms in AS patients and suggest the need for a multidisciplinary approach to patient care. Further research into the shared pathogenic pathways is needed to develop personalized treatment strategies and improve patient management.

Neuroendocrine tumors (NETs) are a group of rare, heterogenous neoplasms that maintain unique morphologic and clinical features of neuroendocrine neoplasia and account for approximately 0.5% of all newly diagnosed malignancies. NETs are divided into two groups based on their histopathological morphology: well-differentiated neuroendocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). Well differentiated NETs are classified as G1, G2, or G3 based on their proliferation rate, whereas NECs are highly proliferative and poorly differentiated by definition [1]. Neuroendocrine neoplasms can occur almost anywhere in the body; however, they are most often seen in the gastrointestinal tract, pancreas, and lungs [2]. The extrahepatic bile duct is one of the rarest primary sites for NETs, accounting for 0.1% to 0.2% of NETs of the gastrointestinal tract [3]. Signet ring cell bile duct NETs are extremely uncommon and have no established incidence and prognosis due to their rarity. There is sparse information available regarding these tumors, and only a few cases have been reported in the literature to date. In this report, we presented the clinical course and surgical management of a 31-year-old female patient with a Klatskin signet ring cell NET.

Background: Hypothermia, as a sign of serious bacterial infection (SBI) in children and infants older than 90 days is poorly characterized, especially in the post-pneumococcal vaccine era.

Objectives: To assess the prevalence of SBI in children and infants presenting to the pediatric emergency department (PED) with reported or documented hypothermia.

Methods: Retrospective data analysis was conducted of all well-appearing children aged 0–16 years who presented with a diagnosis of hypothermia at two tertiary PEDs from 2010 to 2019.

Results: The study comprised 99 children, 15 (15.2%) age 0–3 months, 71 (71.7%) 3–36 months, and 13 (13.1%) > 36 months. The youngest age group had increased length of stay in the hospital (P < 0.001) and increased rates of pediatric intensive care unit admissions (P < 0.001). Empirical antibiotic coverage was initiated in 80% of the children in the 0–3 months group, 21.1% in the 3–36 months group, and 15.4% in > 36 months (P < 0.001). Only one case of SBI was recorded and no bacteremia or meningitis. Hypothermia of unknown origin was the most common diagnosis in all age groups (34%, 42%, 46%), respectively, followed by bronchiolitis (26%) and hypoglycemia (13.3%) for 0–3 month-old children, unspecified viral infection (20%) and otitis media (7%) for 3–36-month old, and unspecified viral infection (23%) and alcohol intoxication (15.2%) in > 36 months.

Conclusion: There is a low incidence of SBI in well-appearing children presenting to the PED with hypothermia and a benign course and outcome in those older than 3 months.

A rise in the incidence of chronic health conditions, notably heart failure, is expected due to demographic shifts. Such an increase places an onerous burden on healthcare infrastructures, with recurring hospital admissions and heightened mortality rates being prominent factors. Efficient chronic disease management hinges on regular ambulatory care and preemptive action. The application of intelligent computational models is showing promise as a key resource in the ongoing management of chronic diseases, particularly in forecasting disease trajectory and informing timely interventions. In this review, we explored a pioneering intelligent computational model by Diagnostic Robotics, an Israeli start-up company. This model uses data sourced from insurance claims to forecast the progression of heart failure. The goal of the model is to identify individuals at increased risk for heart failure, thus enabling interventions to be initiated early, mitigating the risk of disease worsening, and relieving the pressure on healthcare facilities, which will result in economic efficiencies.
