Magnetic Resonance Elastography (MRE) is a phase-contrast technique using conventional Magnetic Resonance Imaging system to visualize propagating shear waves and study the stiffness of tissues. Usually, shear vibrations are applied to the surface of tissues by means of mechanical driver at one point. But in femoral art…

BACKGROUND AND AIM: Previous studies have shown an association between obesity and uterine fibroids (UF). Body roundness index (BRI) is an anthropometric measure associated with obesity. However, the association with UF has not been thoroughly elucidated, and further investigation is required to explore the possible li…

AIMS: Because many recent studies have questioned the accuracy of Doppler echocardiography (D) in determining pulmonary artery systolic pressure (PASP), we performed a detailed literature analysis attempting add clarity. METHODS AND RESULTS: Studies through 2011 comparing D and right heart catheterization (RHC) PASP,…

TITLE: Outcomes from a procedural abortion training program for providers in underserved areas: findings from a four-year evaluation. BACKGROUND: In 2019, the Clinical Abortion Training Centers (CATC) program was initiated in collaboration with the National Abortion Federation to address gaps in abortion training for a…

In this systematic review and meta-analysis of observational studies, we aimed to estimate the associations between prenatal vitamin D status and offspring growth, adiposity and metabolic health. We searched the literature in human studies on prenatal vitamin D status and offspring growth in PubMed, up to July 2017. St…

OBJECTIVE: Guatemala has one of the highest rates of maternal mortality in Central America. A total of 60% of births in Guatemala are attended by traditional Mayan birth attendants, or comadronas. Their prevalence in these communities makes them a valuable resource to bridge home births with safe prenatal care. The obj…

PURPOSE: It has been suggested that statins may exert thermo-protective effects that can reduce mortality on hot days. We aimed to examine the relationship between statin adherence and mortality in days with high temperature. METHODS: Utilizing data from a prior historical new-user cohort study, we analyzed a cohort o…

PURPOSE: Surgery is the only way to cure pheochromocytoma; however, postoperative hemodynamic instability is one of the main causes of serious complications and even death. This study's findings provide some guidance for improved clinical management. PATIENTS AND METHODS: This study was to investigate the factors lead…

OBJECTIVE: the study's objective was to determine impact of COVID-19 on the prognosis of pulmonary embolism. PATIENTS AND METHODS: An analytical multicenter cross-sectional study with retrospective data collection was carried out in three university hospitals and a private clinic in Ouagadougou from March, 2020 to Jul…

OBJECTIVE: Disorders of consciousness (DoC) are acquired conditions of severely altered consciousness. Electroencephalography (EEG)-derived biomarkers have been studied as clinical predictors of consciousness recovery. Therefore, this study aimed to systematically review the methods, features, and models used to derive…

INTRODUCTION:  Precise fibular tunnel placement in posterolateral corner (PLC) reconstruction is crucial in restoring rotational and lateral stability. Despite the recent progress of arthroscopic PLC reconstruction techniques, landmarks for arthroscopic fibular tunnel placement and a comparison to open tunnel pl…

BACKGROUND: The prevalence of obesity in type 1 diabetes has been increasing over the past decades. Multiple studies have demonstrated suboptimal outcomes with dietary control and medical management for obesity and type 2 diabetes. This study's objective was to evaluate insulin and diabetic medication requirements in p…

PURPOSE: The neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte (PLR) ratios have been proposed as emerging markers of inflammation and prognosis in maintenance hemodialysis (MHD) patients. However, to date, no longitudinal performance of these indices is known. The study's purpose was to examine the longitudina…

OBJECTIVE: To describe the self-expanding endobronchial occluder, as utilized in bronchoscopic lung volume reduction, with a 36 month follow-up procedure. METHODS: Twenty-three subjects with severe emphysema were recruited and underwent flexible bronchoscopic placement of self-expanding endobronchial occluders. Outcom…

OBJECTIVES: This clinical prospective study describes how caries preventive measures applied according to caries risk affect new caries incidence in a group of preschoolers, as compared to a group where standardized caries prevention is applied, regardless of risk. METHOD AND MATERIALS: Healthy children, aged four yea…

PURPOSE: We sought to determine whether conjunctival ultraviolet autofluorescence (UVAF), a biomarker of outdoor light exposure, is associated with myopia. METHODS: We performed a cross-sectional study on Norfolk Island and recruited individuals aged ≥ 15 years. Participants completed a sun-exposure questionnai…

The evidence for a role of diet on ovarian cancer prevention remains inconclusive. While many studies have evaluated individual foods and food groups, the evaluation of a comprehensive dietary quality index for predicting cancer risk has received little attention. This study investigates the association between the Hea…

The rationale for introducing self-management plans for the whole chronic obstructive pulmonary disease (COPD) population is uncertain. This study's aim was to investigate whether people with panic disorder (PD), compared to non-panic-disordered (NPD), derived additional educational or psychological benefits from havin…

This study, based upon epidemiological survey data from the United States (U.S.) National Household Surveys on Drug Abuse (NHSDA) from 2000 to 2001, presents new estimates for the risk of developing a hallucinogen dependence syndrome within 24 months after first use of any hallucinogen (median elapsed time approximatel…

BACKGROUND: Adult-onset cases of DSM-III-R major depressive disorder (MDD) often have had a history of mood disturbances and allied clinical features during childhood or adolescence. This study seeks to illuminate these early-life disturbances, as recalled and reported by adult-onset MDD cases (i.e. those whose first e…
