Background: To date, some factors associated with quality of sleep in patients with PCOS have been identified. Previous studies have mainly focused on limited psychological variables related to sleep disorder without evaluating them in a comprehensive framework.

Objective: The aim of the present study was to evaluate the impact of predictive factors on the sleep quality of PCOS patients using structural equation modeling (SEM).

Background: We compared the severity of disease, heart failure (HF) rehospitalization and trend of changes over a 12-month follow-up in clinical and biochemical measurements between dilated cardiomyopathy (DCM) patients and those with left ventricular systolic dysfunction with normal LV size (NLVS). The existing definition of DCM failed to justify our observations in some clinical circumstances resulting in diagnostic and prognostic challenges.

Methods: A total of 77 patients [52 (67.

Background: Workers engaged in dairy farming are exposed to awkward and poor postures that may result in work-related musculoskeletal disorders (WMSDs).

Objective: This study carried out ergonomic interventions in order to eliminate and reduce awkward postures in dairy farming.

Methods: This quasi-experimental study applied rapid entire body assessments (REBA) to evaluate the risks associated with each posture while performing the assigned tasks on a dairy farm in Iran to identify high and very high-risk tasks.

Aim Of The Study: Host and viral factors can influence the clinical course of chronic hepatitis B virus (HBV) infection. Mutations in pre-S1/S2 gene regions are among the most important viral factors determining the HBV infection outcome. The aim of this study was to investigate the role of pre-S1/S2 mutations in HBV infection outcome.

This study provides a phylogeographic insight into the population diversity of strains causing bacterial leaf streak disease of small-grain cereals in Iran. Among the 65 bacterial strains isolated from wheat, barley, and gramineous weeds in eight Iranian provinces, multilocus sequence analysis and typing (MLSA and MLST) of four housekeeping genes (, , , and ), identified 57 strains as pv. undulosa, while eight strains were identified as pv.

Catalytic conversion of actual biomass to valuable chemicals is a crucial issue in green chemistry. This review discusses on the recent approach in the levulinic acid (LA) formation from three prominent generations of biomasses. Our paper highlights the impact of the nature of different types of biomass and their complex structure and impurities, different groups of catalyst, solvents, and reaction system, and condition and all related pros and cons for this process.

The aim of this study was to compare pregnancy, childbirth, and neonatal outcomes in women with different phenotypes of polycystic ovary syndrome (PCOS) with healthy women. A prospective cohort study from the beginning to the end of pregnancy for 41 pregnant women with PCOS (case) and 49 healthy pregnant women (control) was completed. Based on the presence or absence of menstrual dysfunction (M), hyperandrogenism (HA), and polycystic ovaries (PCO) on ultrasound, the PCOS (case) group were divided into three phenotypes (HA + PCO ( = 22), M + PCO ( = 9), HA + M+PCO ( = 10).

Bacteria of the Pseudomonas putida group are studied for a large panel of properties ranging from plant growth promotion and bioremediation to pathogenicity. To date, most of the classification of individual pseudomonads from this group relies on 16S RNA gene analysis, which is insufficient for accurate taxonomic characterization within bacterial species complexes of the Pseudomonas putida group. Here, a collection of 20 of these bacteria, isolated from various soils, was assessed via multi-locus sequence analysis of rpoD, gyrB and rrs genes.

Introduction: Lung transplantation is the only successful treatment option for patients experiencing end-stage lung disease. Results have improved significantly in the last decade; however, the number one limiting factor is still the shortage of donor lungs. Due to the discrepancy between available donor lungs and patients awaiting lung transplantation, many centers have reintroduced donation after cardiac death (DCD).

Objective: Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by one or more of the following features: intraluminal thrombus organization, fibrous stenosis, and complete obliteration of major pulmonary arteries, amenable to significant improvement by pulmonary endarterectomy (PEA) or balloon pulmonary angioplasty, and medical treatments with vasodilators. Because treatment practices and outcomes differ in Europe versus Japan, we hypothesized that population-based characteristics of pulmonary vascular phenotypes may exist in Austria compared with Japan. The objectives of this study were to analyze clinical characteristics, hemodynamics, and PEA specimens in consecutive patients with CTEPH undergoing PEA in Austria and Japan.

Article Synopsis
  • A study highlights the rising rates of inflammatory bowel disease (IBD) in Iran and introduces the Iranian Registry of Crohn's and Colitis (IRCC) as a response to this growing health concern.
  • The IRCC is a comprehensive, multicenter registry involving over 100 gastroenterologists, utilizing a standardized questionnaire to gather critical patient data, which has shown reliable results in a pilot study of 553 patients.
  • This registry is the first of its kind in the Middle East, aiming to enhance IBD patient care and provide valuable information for healthcare policy makers to better address IBD in Iran.

Background: Outcomes of emergency general surgery (EGS) procedures on hematopoietic stem cell transplant (HST) recipients have not been defined in a large, national database. Whether EGS during HST engraftment admission, or in HST patients with graft versus host disease (GVHD) results in worse outcomes is unknown.

Methods: The National Inpatient Sample (NIS) was examined for patients with a history of BMT between 2001 and 2014.

Background: The present study aimed to compare dietary intake and lifestyle behaviour in women with polycystic ovarian syndrome (PCOS) and healthy women.

Methods: One hundred and sixty healthy women (partner with male infertility) were recruited to a control group; 168 women with PCOS (diagnosed on ultrasound) were recruited to a case study group for this cross-sectional comparative study. The case group was classified into three phenotypes based on the presence or absence of menstrual disorder (M), hyperandrogenism (HA) and polycystic ovary according to sonography (PCO): HA+PCO (n = 53), PCO+M (n = 57) and M+HA+PCO (n = 66).

Question Addressed By The Study: The value of induction therapy in lung transplantation is controversial. According to the ISHLT, only about 50% of patients transplanted within the last 10 years received induction therapy. We reviewed our institutional experience to investigate the impact of induction therapy on short- and long-term outcomes.

Problem: Inappropriate activation of the immune system, particularly the imbalance of T-helper type 17 (Th17)/regulatory T (Treg) cells is thought to play considerable roles in preeclampsia (PE). To investigate the probable effects of the adaptive immune system in the pathophysiology of PE, we analyzed the dynamic changes of Th17/Treg cells, cytokines profile, and transcription pattern of Th17/Treg-related genes and microRNAs (miRNAs) in 50 women suffering from PE in comparison with 50 healthy pregnant women.

Methods: Expressions of cytokines, specific transcription factors, and related miRNAs were measured by real-time polymerase chain reaction (PCR).

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) results from persistent pulmonary vascular obstructions, presumably due to inflammatory thrombosis. Because estimates of thrombus volume at diagnosis have no predictive value, we investigated the role of the thrombosis marker, D-dimer, and the inflammation marker, C-reactive protein (CRP), for predicting outcomes in CTEPH.

Methods: A total 289 consecutive patients with CTEPH were followed for 57 (median 45 to 69) months.
