The 4th iteration of the Chicago Classification (CC v4.0) for esophageal motility disorders offers more restrictive criteria for the diagnosis of Ineffective Esophageal Motility (IEM) compared to version 3.0 (CC v3.0). In light of the updated criteria for IEM, we aimed to characterize and compare the patients who retained their IEM diagnosis to those who were reclassified as normal motility, and to evaluate the clinical impact of the newly introduced CC v4.0. 

Lockdowns and quarantines during the COVID-19 pandemic influenced healthcare services' usage patterns such as emergency department (ED) attendance. During the pandemic, Israel issued three lockdowns (March-May 2020, September-October 2020, and December 2020-February 2021) to mitigate the spread of COVID-19. Little is known about the impact of these lockdowns on ED attendance for injuries in the diverse population of Northern Israel.

Severe malnutrition following one-anastomosis gastric bypass (OAGB) remains a concern. Fifty studies involving 49,991 patients were included in this review.

 Clinical chorioamnionitis refers to the presence of maternal fever (≥38°C) and at least 2 clinical signs: (1) maternal tachycardia (>100 bpm), (2) fetal tachycardia (>160 bpm), (3) maternal leukocytosis >15,000/mm², (4) purulent vaginal discharge, and (5) uterine tenderness. Few data exist to guide the appropriate management of women with isolated intrapartum fever in the absence of other clinical signs suggesting chorioamnionitis. Objective: This study compared maternal and neonatal infectious outcomes and microbiological outcomes between women with isolated intrapartum fever and women with clinical chorioamnionitis.

The continuity equation (CE) used for evaluating aortic stenosis (AS) is based on values obtained from transthoracic echocardiography (TTE) with the assumption that the left ventricular outflow tract (LVOT) has a circular shape. Transesophageal echocardiography (TEE) may be used for accurate measurement of the LVOT cross-sectional area (CSA). Previous studies have focused on fusion from TEE for LVOT-CSA measurement and TTE for velocity time integrals (VTI) calculations.

Objectives: To assess aortic valve area (AVA) using parameters obtained exclusively from TEE as an alternative approach.

The aim of this anonymous online study was to explore the yoga practice of breast cancer survivors to determine if yoga dosage (frequency and duration of practice) was related to stress, anxiety, and self-reported health in female survivors.

Prolonged pulmonary air leak after lung surgery is defined as a postoperative air leak of more than five days duration. Prolonged air leak after lung resection (wedge, segmentectomy, or lobectomy) is one of the most common complications known well to every thoracic surgeon. This adverse event leads to prolonged hospital length of stay, increased medical costs, higher readmission rates and strongly affects morbidities.

One-anastomosis gastric bypass (OAGB) is an emerging metabolic bariatric surgery (MBS) type used in both primary OAGB (pOAGB) and revisional OAGB (rOAGB). We studied ≤30-day outcomes of pOAGB and rOAGB and identified predictors of early complications.

It has been the policy of Rambam Maimonides Medical Journal to limit the number of editorials published. However, silence and standing on the sidelines is not an option in light of the atrocities and inhumanity we witnessed on October 7. The savagery of the Hamas massacre was executed indiscriminately upon children, women, older people (some of whom are Holocaust survivors), infants, and even medical professionals caring for the casualties. Currently, there are about 230 women, men, children, and babies being held hostage by Hamas; among them are cancer patients and others with serious disorders, doctors, and other medical professionals. We cannot rest and must address the plight of our hostages who are being held by terrorists motivated by hatred and showing no respect for life, whether that of their enemies, their own people, or even themselves.

Giardia duodenalis (Gd) causes intestinal parasitosis. The involvement of the intestinal microbiome in determining the infection's clinical phenotype is unknown. Objective: Investigate the fecal microbiome features in dogs with giardiasis.

Despite recent significant strides towards acceptance, inclusion, and equality, members of the queer community still face alarming mental health disparities, being almost up to three times more likely to suffer from depression, anxiety, and suicidal thoughts compared with their heterosexual counterparts. These unique psychological challenges are due to discrimination, stigmatization, and identity-related struggles, and can potentially benefit from generative conversational Artificial Intelligence (AI). As the latest advancement in the field of AI, conversational agents and chatbots can imitate human conversation, and support mental health, fostering diversity and inclusivity, combating stigma, and countering discrimination. On the other hand, if not properly designed, they can harm and perpetuate exclusion and inequities. Objective: This study aims to examine the impact of generative conversational AI on the queer community.

Examines the efficacy of MSH6 and PMS2 immunohistochemistry (IHC) as a screening method for Lynch syndrome in endometrial cancer patients.

The Jewish Ultra-Orthodox (UO) population is an under-vaccinated minority group that has been disproportionally affected by outbreaks of vaccine-preventable diseases (VPD) such as measles and polio. Underlying reasons remain poorly characterized. We aimed to identify vaccination barriers and enablers in this population.
