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: Solid pseudopapillary neoplasms (SPNs) of the pancreas are rare tumors arising from pancreatic tissue, predominantly affecting young women and possessing low malignant potential. Extrapancreatic SPNs are exceedingly uncommon. According to data from the English literature, only 30 cases of extrapancreatic SPNs had been reported by 1990, accounting for less than 1% of all reported SPNs from 2004 to 2018. The testis, paratesticular region, and ovary are the more frequently documented sites of these tumors [1,2]. Notably, to the best of our knowledge, no cases of SPN originating in the diaphragm have been reported in the English literature to date. The prevailing theory suggests that SPNs behave similarly regardless of whether they originate in the pancreas or in extrapancreatic locations. We present the case of a 79-year-old female with a history of lung and endometrial cancer, who was diagnosed with a liver lesion during a routine follow-up 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG PET/CT). During surgery, the lesion was resected from the diaphragm and was confirmed to be consistent with the pathological findings of SPN.

Background: The correlation between epidural analgesia and successful Trial of Labor After Cesarean delivery (TOLAC) remains controversial.

Objectives: To explore this correlation considering the indication for previous cesarean section (CS).

Methods: We accessed an electronic database of an obstetrics department at a university tertiary medical center. All patients admitted for a TOLAC at term with a live singleton fetus with cephalic presentation between January 2015 and December 2021 were included. The primary outcome was the mode of delivery, based on the previous CS indication. Univariate and multivariate analyses were performed to identify the effect of epidural analgesia on TOLAC success.

Results: Overall, 1522 candidates for TOLAC were included, with previous CS due to arrest of descent in 261 cases (17.1%). Epidural analgesia was administered in 1098 deliveries (72.1%), and 282 women (18.5%) underwent a repeat CS. Women in the epidural group were younger, had higher body mass index, lower parity, and more frequent induction of labor. Prior vaginal birth after cesarean was more common in the non-epidural group. Univariate analysis showed a higher rate of epidural analgesia in repeat CS cases. However, in multivariable logistic regression, epidural analgesia was not significantly associated with the risk of repeat CS, both among women whose prior CS was for arrest of descent and among those with other indications.

Conclusions: The employment of epidural analgesia seems to have no observable influence on successful outcomes of TOLAC, regardless of the indication for the preceding CS. These findings imply that epidural anesthesia in TOLAC is safe.

Background: Ramadan, one of the core tenets of Islam, requires a rigorous fasting regimen from dawn until sunset, during which practitioners abstain from all forms of food and drink. This substantial alteration in daily habits raises pertinent questions regarding its potential implications for cardiovascular health.

Objectives: To analyze the incidence of myocardial infarction (MI) throughout the Ramadan fasting period.

Methods: We retrospectively compared the incidence of MI occurring during Ramadan with that observed during the corresponding non-Ramadan months from 2010 to 2021 using medical records of Muslim patients admitted to the Galilee Medical Center. Ramadan's timing varies from year to year. We used a 3-year comparative framework to ensure seasonal alignment.

Results: During the study period and within a well-defined geographic region, we found that among Muslims, there were 405 MIs: 201 during Ramadan and 204 during non-Ramadan periods, P = 0.282.

Conclusions: The incidence of MI during Ramadan remained stable, indicating that the fasting practice does not significantly heighten the risk of MI.

Background: Remnant cholesterol (RC), the cholesterol content of triglyceride-rich lipoproteins, is an emerging residual risk factor for atherosclerotic cardiovascular disease. Data on the prognostic significance after an ischemic stroke are limited.

Objectives: To investigate the association between RC and risk for cardiac events following hospitalization for an ischemic stroke.

Methods: Data were collected for 5697 patients (39.5% women) affiliated with Clalit Health Services and hospitalized with an acute ischemic stroke. Adjusted Cox-regression models were used to estimate the association between RC percentiles, calculated using a routine post-discharge lipid profile, and risk for future myocardial infarction (MI) or coronary revascularization.

Results: Mean age was 69 ± 10 years; 78% were treated by lipid-lowering therapies. During median follow-up of 22 months, a MI or coronary revascularization event occurred in 243 patients. After multivariable adjustment including lipid-lowering therapies and non-HDL-C, RC was associated with higher MI or revascularization risk: hazard ratio (95% confidence interval): 1.42 (1.10-1.85), 1.50 (1.11-2.02), 1.62 (1.09-2.40), and 1.93 (1.22-3.06), in those with RC percentiles ≥ 50th (23.3 mg/dl), ≥ 75th (31.8 mg/dl), ≥ 90th (42.1 mg/dl), and ≥ 95th (49.1 mg/dl), compared to < 50th percentile. When RC and non-HDL-C levels were discordant, the level of RC better reflected higher risk for adverse cardiac events.

Conclusions: Elevated RC following acute ischemic stroke is a risk factor for MI or coronary revascularization, independent of lipid-lowering therapies and non-HDL-C and may serve as a residual cardiovascular risk marker and potential treatment target in patients with ischemic stroke.

Background: The benefits of corticosteroid administration for suspected premature birth (PTB) are widely accepted. Although a single course of antenatal corticosteroids is generally considered to be safe, there are concerns regarding the safety and benefit of multiple courses. Nevertheless, many women who present with symptoms of PTB do not deliver early.

Objectives: To assess how often we used corticosteroid appropriately in our clinical practice in women who presented with risk of PTB.

Methods: Clinical data were retrospectively collected on patients who were admitted to our clinic between September 2014 and August 2015 due to risk of PTB and who were treated with prenatal corticosteroids.

Results: We identified 305 patients at risk of PTB who were treated with corticosteroids; 42.3% delivered < week 34, 22.5% delivered between weeks 34 and 37, and 35.1% delivered > 37 weeks. In women who delivered after week 37, the more time that elapsed between corticosteroids administration and delivery, the lower the pH and the APGAR scores were. Only 26% of patients delivered 2-14 days after the last steroids course of treatment.

Conclusions: The rate of term deliveries at our center after receiving antenatal corticosteroids due to prior symptoms of preterm labor was 35.1%. The ratio of maternal antenatal corticosteroid administration for potential versus actual PTB at < 37 weeks of gestation was not optimal but acceptable.

Background: Epidemiological studies have demonstrated an association between sleep deprivation (SD) and ischemic heart disease.

Objectives: To determine the effect of SD on the endothelial function and on the inflammatory profile of young healthy men following 24 hours of work without sleep.

Methods: Fourteen healthy men (age 31.3 ± 2.4 years) participated in our prospective study. Endothelial function was evaluated by the brachial artery method, measuring flow medicated percent change (FMD%) of the brachial artery by a linear array ultrasound early in the morning. Interleukin 1 (IL-1) and interleukin 6 (IL-6) were measured in saliva by ELISA.

Results: Basic FMD% was 6.7 ± 6.8%, and following SD 1.7 ± 3.3% (P = 0.009). A 5.0 ± 6.1% decrease was measured after SD. IL-1 levels increased after SD from 36 ± 21 pg/ml to 47 ± 24 pg/ml (P = 0.004), and IL-6 levels increased from 22 ± 07 pg/ml to 36 ± 11 pg/ml (P = 0.0005). A negative correlation was found between the change (decrease) in FMD% and the change (increase) in IL-1 level (r = -0.813; P = 0.001). A negative correlation was found between the decrease in FMD% and the increase in IL-6 level (r = -0.735; P = 0.003).

Conclusions: SD led to endothelial dysfunction with increase in markers of inflammation (IL-1 and IL-6), with an inverse correlation between the change (decrease) in endothelial function and the change (increase) in IL-1 and in IL-6.

Background: Increased utilization of imaging modalities has led to a significant rise in the detection of incidental thyroid nodules (ITN). Discrepancies in the prevalence of thyroid nodules with malignant potential exist worldwide.

Objectives: To analyze demographic and clinical data among patients with thyroid nodules in our geographic region.

Methods: The medical records of patients diagnosed with symptomatic or incidental thyroid nodules at the Galilee Medical Center between 2018 and 2023 were reviewed. Demographic and clinical data were collected and analyzed.

Results: The study population included 402 patients with thyroid nodules, 292 females. Symptomatic patients were younger (mean age 55.9 vs. 60.8 years) and had larger nodules (mean size 2.5 vs. 2.1 cm) compared to incidentally diagnosed patients (P < 0.001, P < 0.001, respectively). Male patients demonstrated a higher rate of malignancy for both symptomatic and incidental nodules compared to females (P < 0.05). Pathological examination revealed that malignant nodules were smaller (mean size 2.10 cm vs. 2.87 cm) and detected at a younger age (mean age 48.56 years vs. 56.5 years), compared to benign nodules (P < 0.05, P < 0.01, respectively).

Conclusions: We found a higher prevalence of both symptomatic and ITN among females. However, malignant thyroid nodules were more frequently observed in males. Notably, malignant nodules tended to be smaller and were more commonly diagnosed in younger individuals compared to benign nodules. These findings highlight significant sex and age disparities in the occurrence and characteristics of thyroid nodules, emphasizing the need for tailored diagnostic and management strategies.
