Background: Hypertensive disorders during pregnancy can lead to significant adverse outcomes. Currently, no established and effective tests have a high predictive value for preeclampsia toxemia (PET) severity and its associated adverse outcomes.

Objectives: To investigate the correlation between the aspartate aminotransferase-to-platelet ratio index (APRI) and the risk of obstetrical and neonatal adverse outcomes in women with PET.

Methods: We conducted a population-based cohort study at a tertiary medical center, which included all women who delivered between the years 2020 and 2022 and were diagnosed with PET. Women with incomplete records, multiple gestations, and fetal malformations were excluded. The median APRI of the cohort was the cut-off point to compare the risk of obstetrical and neonatal complications between low and high APRI scores. A multivariable logistic regression was used to adjust for confounders.

Results: The study included 513 women with PET who met the inclusion criteria. The median APRI score was used as a cut-off value, resulting in 255 women with an APRI score < 0.26 and 258 with a score > 0.26. A higher APRI score was significantly correlated with a small for gestational age (SGA) newborn and preterm delivery before 34 weeks after controlling for parity, previous cesarean delivery (CD), and maternal age (adjusted odds ratio 1.60, 95% confidence interval 1.01–2.55; P = 0.047, adjusted hazard ration 1.75, 95% confidence interval 1.12–3.09, P = 0.047).

Conclusions: In patients with PET, an APRI score > 0.26 was associated with an increased risk for SGA and preterm deliveries.

Background: Behcet's syndrome (BS) is a multisystem syndrome that typically manifests as recurrent oral and genital ulcers, as well as other systemic manifestations. Few studies describing the characteristics of BS among Israeli patients have been published.

Objectives: To describe the characteristics of BS patients and to compare Jewish and Arab subpopulations.

Methods: We retrospectively reviewed electronic medical records and extracted demographic, clinical, laboratory, and medication data for each patient. We compared the Jewish and Arabic BS patients.

Results: The cohort included 98 patients. Males constituted 49 (50%); mean age at the time of diagnosis was 29.9 years; 71 (72.4%) were Arab and 27 (27.6%) were Jewish. Oral ulcers were evident in 93 patients (94.9%) and genital ulcers in 54 (55.1%). Involvement of the skin, joints, eyes, gastrointestinal tract, and neurologic and vascular systems were demonstrated among 42 (42.9%), 57 (58.2%), 47 (48.0%), 8 (8.2%), 10 (10.2%), and 15 (15.3%), respectively. HLA B51 was positive in 24 of 37 (64.9%). Pathergy was positive in 8 of 12 (66.7%). Colchicine was used in 82 (83.7%), azathioprine 47 (48%), methotrexate 16 (16.3%), apremilast 10 (10.2%), cyclosporine-A 8 (8.2%), adalimumab 26 (26.5%), infliximab 12 (12.2%), cyclophosphamide 1 (1.0%), tocilizumab 2 (2.0%), and anti-coagulation 6 (6.1%). The Arab and Jewish subpopulations were significantly different regarding male proportion, 40 (56.3%) vs. 9 (33.3%), P = 0.042.

Conclusions: BS is more common among Arabs in northern Israel, but no significant clinical or demographic differences were found except for a higher proportion of male patients among Arabs.

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.

Background: Cardiac implantable electronic devices (CIEDs) with endocardial leads crossing the tricuspid valve can lead to or worsen tricuspid regurgitation (TR), causing substantial morbidity and mortality. Despite a recent randomized controlled study revealing a low short-term incidence of device-related TR (DRT) post-CIED implantation, uncertainties persist regarding the efficacy of intra-procedural 2-dimensional transthoracic echocardiography (2DTTE) in preventing long-term TR.

Objectives: To conduct a long-term follow-up study on patients with CIED implants based on a previous study conducted at our hospital.

Methods: In a retrospective study at Assuta Ashdod Medical Center (2018–2019), patients undergoing de-novo CIED implantation with (n=39, group 1) or without (n=51, group 2) intra-procedural 2DTTE were analyzed. Clinical, demographic, and long-term (> 1 year) echocardiographic data were collected and compared.

Results: The study included 90 patients (mean age 72.3 ± 11.0 years, 63% male, 23% ICD, 50% active leads, follow-up 32.8 ± 11 months). TR aggravation was found in 25% of patients (13 in group 1, 10 in group 2), with no statistical difference between groups. Multivariate analysis identified a history of atrial fibrillation (AF) as the sole significant factor in long-term TR deterioration (OR=3.44, 95%CI 1.13–10.43, P = 0.029). Other clinical, demographic, echocardiographic, and device-related factors did not significantly contribute to long-term DRT.

Conclusions: After one-year post-CIED implantation, the incidence of DRT significantly increases. Intra-procedural 2DTTE does not effectively reduce long-term DRT, suggesting that implantation-related mechanisms are less likely the primary cause. AF likely plays a major role in the pathogenesis of long-term TR in this subset post-CIED implantation.

Phosphoglucomutase 1 (PGM1) deficiency is a rare genetic disorder that affects glycogen metabolism and manifests as a multisystem disease. Most patients present with oropharyngeal malformations, cardiomyopathies, elevated liver enzymes, and hypoglycemia. Treatment with D-galactose has been shown to improve symptoms. Our patient presented with PGM1 deficiency. She conceived spontaneously. Throughout her pregnancies, our patient was monitored by a multidisciplinary team of cardiologists, endocrinologists, and physicians with experience in high-risk pregnancy. She delivered twice by cesarean section. Our case highlights the importance of a multidisciplinary approach and individualized management of prenatal and postpartum care of a patient with a PGM1 deficiency. To the best of our knowledge, there have been no reports about a PGM1-deficient patient who conceived and delivered.

Background: Cardiac amyloidosis (CA) is characterized by the extracellular deposition of misfolded protein in the heart. Precise identification of the amyloid type is often challenging, but critical, since the treatment and prognosis depend on the disease form and the type of deposited amyloid. Coexistence of clinical conditions such as old age, monoclonal gammopathy, chronic inflammation, or peripheral neuropathy in a patient with cardiomyopathy creates a differential diagnosis between the major types of CA: amyloidosis light chains (AL), amyloidosis transthyretin (ATTR) and amyloidosis A (AA).

Objectives: To demonstrate the utility of the Western blotting (WB)-based amyloid typing method in patients diagnosed with cardiac amyloidosis where the type of amyloid was not obvious based on the clinical context.

Methods: Congo red positive endomyocardial biopsy specimens were studied in patients where the type of amyloid was uncertain. Amyloid proteins were extracted and identified by WB. Mass spectrometry (MS) of the electrophoretically resolved protein-in-gel bands was used for confirmation of WB data.

Results: WB analysis allowed differentiation between AL, AA, and ATTR in cardiac biopsies based on specific immunoreactivity of the electrophoretically separated proteins and their characteristic molecular weight. The obtained results were confirmed by MS.

Conclusions: WB-based amyloid typing method is cheaper and more readily available than the complex and expensive gold standard techniques such as MS analysis or immunoelectron microscopy. Notably, it is more sensitive and specific than the commonly used immunohistochemical techniques and may provide an accessible diagnostic service to patients with amyloidosis in Israel.

Background: Long-term outcome data for bariatric surgery in patients with severe obesity (SO) (body mass index [BMI] ³ 50 kg/m2) are scarce.

Objectives: To compare perioperative morbidity and long-term outcomes between patients with SO and non-SO (NSO).

Methods: Patients with SO who underwent primary bariatric surgery with a follow-up ³ 5 years were age- and gender-matched with NSO patients in a retrospective, case-control study. Data included demographics, BMI, co-morbidities, early outcomes, current and nadir weight, co-morbidity status, and general satisfaction.

Results: Of 178 patients, 49.4% were male, mean age 44.5 ± 14 years. Mean preoperative BMI was 54.7 ± 3.6 and 41.8 ± 3.8 kg/m2 in SO and NSO, respectively (P = 0.02). Groups were similar in preoperative characteristics. Depression/anxiety was more prevalent in NSO (12.4% vs. 3.4%, P = 0.03). Obstructive sleep apnea was higher in SO (21.3% vs. 10.1%, P = 0.04). Sleeve gastrectomy was performed most often (80.9%), with a tendency toward bypass in SO (P = 0.05). Early complication rates were: 13.5% in SO and 12.4% in NSO (P = 0.82). Mean follow-up was 80.4 ± 13.3 months. BMI reduction was higher in SO (31.8 ± 5.9 vs. 26.8 ± 4.2 kg/m2, P < 0.001) and time to nadir weight was longer (22.1 ± 21.3 vs. 13.0 ± 12.0 months, P = 0.001). Co-morbidity improvement and satisfaction were similar.

Conclusions: Patients with SO benefited from bariatric surgery with reduced BMI and fewer co-morbidities. No added risk of operative complications was found compared to patients with NSO.

Background: There is an unmet need for real-world data regarding laboratory results, co-morbidities, and medication use prior to the first symptoms of amyotrophic lateral sclerosis (ALS). Researchers must identify specific subpopulations at risk for developing ALS and understand pathogenic mechanisms preceding the clinical presentation of ALS as well as possible subclinical disease manifestations.

Objectives: To valuate the role of laboratory results, co-morbidities, and medication use prior to the first symptoms of patients with ALS in Israel so that specific subpopulations at risk for developing ALS can be identified and for possible subclinical disease manifestations. To understand pathogenic mechanisms preceding the clinical presentation of ALS.

Methods: At the ALS clinic at Tel Aviv Sourasky Medical Center, 259 ALS patients insured by Maccabi Healthcare Services and seen between January 1998 and December 2017 were included. Comparisons of demographics, co-morbidities, medications taken, history of trauma, and laboratory tests prior to disease onset were performed between patients and 1295 matched controls.

Results: Prior to disease presentation, ALS patients had a higher frequency of hypertension and cardiovascular disease; presented more frequently with trauma and viral infections; more frequently used analgesics, non-steroidal anti-inflammatory drugs, narcotics, antibiotics, and antiviral medications; and had higher creatine kinase levels.

Conclusions: ALS patients showed higher frequency of cardiovascular disease prior to diagnosis, as well as higher frequency of trauma, infections, and pain medication usage.

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.

Background: Intrathoracic cancer can cause hyponatremia, but it is uncertain whether mild hyponatremia in the outpatient setting should be regarded as an early sign of intrathoracic cancer.

Objectives: To evaluate the risk of undiagnosed intrathoracic cancer in patients with new persistent mild hyponatremia.

Methods: We conducted a retrospective cohort study using the electronic health record database of a large healthcare organization. The hyponatremia group included patients with sodium concentration of 130–134 mmol/L twice, after a previous normal value and without previous history of cancer or diseases related to hyponatremia. A control group with normal sodium concentration was matched by sex, age, and year of testing. We measured specific intrathoracic cancer incidence during 3 years of follow-up after sodium concentration test date. A logistic regression was used to adjust for further clinical information including smoking history, symptoms, and medications.

Results: The study comprised 1539 participants with mild hyponatremia and 7624 matched controls. New intrathoracic cancer diagnosis was more common in the hyponatremia group during a 3-year follow-up; 1.49% in the hyponatremia group and 0.39% in the control group, crude odds ratio (OR) 3.84, 95% confidence interval (95%CI) 2.22–6.63. After adjustment, hyponatremia remained a significant risk factor for the diagnosis of intrathoracic cancer; adjusted OR 3.61, 95%CI 2.08–6.28.

Conclusions: New mild persistent hyponatremia might be a significant predictive marker to a yet undiagnosed intrathoracic cancer.

Background: Changes accommodating requirements of religious authorities in Israel resulted in the Brain and Respiratory Death Determination Law (BRDDL), which came into effect in 2009. These included considering patient wishes regarding the brain respiratory death determination (BRDD), mandatory performance of apnea and ancillary testing, establishment of an accreditation committee, and accreditation required for physicians performing BRDD.

Objectives: To assess the impact of the legislation from 2010–2019.

Methods: Data collected included the number of formal BRDDs and accredited physicians. Obstacles to declaring brain death and interventions applied were identified.

Results: Obstacles included lack of trained physicians to perform BRDD and interpret ancillary test results, inability to perform apnea or ancillary testing, and non-approach to next-of-kin objecting to BRDD. Interventions included physician training courses, additional ancillary test options, and legal interpretation of patient wishes for non-determination of BRD. As a result, the number of non-determinations related to next-of-kin objecting decreased (26 in 2010 to 5 in 2019), inability to perform apnea or ancillary testing decreased (33 in 2010 to 2 in 2019), and number of physicians receiving accreditation increased (210 in 2010 to 456 in 2019). Last, the consent rate for organ donation increased from 49% to 60% in 2019.

Conclusions: The initial decrease in BRDDs has reversed, thus enabling more approaches for organ donation. The increased consent rate may reflect in part the support of the rabbinate and confidence of the general public that BRDD is performed and monitored according to strict criteria.

Background: Self-management, an active life routine, and adherence to physical activity are effective in the management of low back pain (LBP). However, delivering effective education and reassurance to patients can be a difficult for practitioners. The enhanced transtheoretical model intervention (ETMI) has shown to be successful and cost effective. The intervention focuses on educating practitioners to reassure patients, empower them to increase physical activity, and improve their self-efficacy.

Objectives: To assess whether ETMI can be implemented among primary care practitioners and to examine whether it reduces pain, disability, and fear avoidance as well as decreasing healthcare utilization. This protocol outlines the methodology for the implementation of ETMI through a hybrid implementation–effectiveness design.

Methods: Two qualitative and mixed-method studies provided a basis for an implementation prospective cohort study. Discussions are followed by a prospective cohort study with pre-and post-intervention measures as well as descriptions retrieving economic and therapeutic outcome data from the Maccabi Healthcare Services (MHS) databases. In addition, a fourth qualitative study was conducted at the midpoint of the implementation to evaluate the process by measuring the perceptions and practice of practitioners. The intervention group was 220 primary care practitioners and their patients (~n=10,000) from the central district of MHS. The control data was provided by other care districts with similar socioeconomic makeup (~n=40,000).

Conclusions: We evaluated the process and outcomes of the implementation of ETMI. We investigated the relationship between the care received (ETMI against treatment as usual) and healthcare utilization, costs, and patient-clinical outcomes.

Background: A paraovarian cyst (POC) is located between the ovary and the fallopian tube. In many cases POCs are diagnosed and managed as ovarian cysts. But since POC are a distinct entity in their clinical presentation and surgical intervention, they should be better defined.

Objectives: To describe the clinical perioperative and operative characteristics of patients with POCs in order to improve pre-operative diagnosis and management.

Methods: A retrospective cohort study of patients with an operative diagnosis of POC between 2007 and 2019 in a single university-affiliated tertiary care medical center was included. Demographic characteristics as well as symptoms, sonographic appearance, surgery findings, and histology results were retrieved from electronic medical records.

Results: During the study period 114 patients were surgically diagnosed with POC, 57.9% were in their reproductive years and 24.6% were adolescents. Most presented with abdominal pain (77.2%). Preoperative sonographic exams accurately diagnosed POC in only 44.7% of cases, and 50.9% underwent surgery due to suspected torsion, which was surgically confirmed in 70.7% of cases. Among women with confirmed torsion, 28.9% involved the fallopian tube without involvement of the ipsilateral ovary. Histology results showed benign cysts in all cases, except two, with a pathological diagnosis of serous borderline tumor.

Conclusions: POC should always be part of the differential diagnosis of women presenting with lower abdominal pain and sonographic evidence of adnexal cysts. If POC is suspected there should be a high level of suspicion for adnexal torsion and low threshold for surgical intervention, especially in adolescent, population who are prone to torsion

Background: Tricuspid regurgitation (TR) is associated with adverse prognosis in various patient populations, but currently no data is available about the prevalence and prognostic implication of TR in ST-segment elevation myocardial infarction (STEMI) patients.

Objectives: To investigate the possible implication of TR among STEMI patients.

Methods: We conducted a retrospective study of STEMI patients undergoing primary percutaneous coronary intervention (PCI) and its relation to major clinical and echocardiographic parameters. Patient records were assessed for the prevalence and severity of TR, its relation to the clinical profile, key echocardiographic parameters, in-hospital outcomes, and long-term mortality. Patients with previous myocardial infarction or known previous TR were excluded.

Results: The study included 1071 STEMI patients admitted between September 2011 and May 2016 (age 61 ± 13 years; predominantly male). A total of 205 patients (19%) had mild TR while another 32 (3%) had moderate or greater TR. Patients with significant TR demonstrated worse echocardiographic parameters, were more likely to have in-hospital complications, and had higher long-term mortality (28% vs. 6%; P < 0.001). Following adjustment for significant clinical and echocardiographic parameters, mortality hazard ratio of at least moderate to severe TR remained significant (hazard ratio 2.44; 95% confidence interval 1.06–5.62; P = 0.036) for patients with moderate-severe TR.

Conclusions: Among STEMI patients after primary PCI, the presence of moderate-severe TR was independently associated with adverse outcomes and significantly lower survival rate

Background: Osteoporosis is a common medical condition in older ages. A devastating result of osteoporosis may be a hip fracture with up to 30% mortality rate in one year. The compliance rate of osteoporotic medication following a hip fracture is 20% in the western world.

Objectives: To evaluate the impact of the fracture liaison service (FLS) model in the orthopedic department on patient compliance following hip fracture

Methods: We performed a retrospective review of all patients with hip fracture who were involved with FLS. We collected data regarding kidney function, calcium levels, parathyroid hormone levels, and vitamin D levels at admission. We educated the patient and family, started vitamin D and calcium supplementation and recommended osteoporotic medical treatment. We phoned the patient 6–12 weeks following the fracture to ensure treatment initiation.

Results: From June 2018 to June 2019 we identified 166 patients with hip fracture who completed at least one year of follow-up. Over 75% of the patients had low vitamin D levels and 22% had low calcium levels at admission. Nine patients (5%) died at median of 109 days. Following our intervention, 161 patients (96%) were discharged with a specific osteoporotic treatment recommendation; 121 (73%) received medication for osteoporosis on average of < 3 months after surgery. We recommended on injectable medications; however, 51 (42%) were treated with oral biphsophonate.

Conclusions: FLS improved the compliance rate of osteoporotic medical treatment and should be a clinical routine in every medical center
