Abstract Aims Unexplained syncope is an important clinical challenge. The influence of age at first on the final diagnosis not well studied. Methods and results Consecutive head-up tilt patients (n = 1928) evaluated for unexplained were stratified into groups <30, 30–59, ≥60 years based syncope. Clinical characteristics analysed in relation to investigation. had a bimodal distribution with peaks 15 70 years. Prodromes (64 vs. 26%, P < 0.001) vasovagal (VVS, 59 19%, more common...
Abstract Aims Tilt testing (TT) is recognized to be a valuable contribution the diagnosis and pathophysiology of vasovagal syncope (VVS). This study aimed assess influence age on TT responses by examination large patient cohort. Methods results Retrospective data from three experienced European Syncope Units were merged include 5236 patients investigated for suspected VVS Italian protocol. testing-positivity rates haemodynamics analysed across age-decade subgroups. Of patients, 3129 (60%)...
Background: Orthostatic hypotension (OH) is a major sign of cardiovascular autonomic failure leading to orthostatic intolerance and syncope. traditionally divided into classical OH (cOH) delayed (dOH), but the differences between two variants are not well-studied. We performed systematic clinical neuroendocrine characterization patients in tertiary syncope unit. Methods: Among 2,167 consecutive (1,316 women, 60.7%; age, 52.6 ± 21.0 years) evaluated for unexplained severe with standardized...
Abstract Aims Syncope is a common condition with many possible causes, ranging from benign to life-threatening aetiologies. Establishing diagnosis can be difficult, and specialized syncope units, using cardiovascular autonomic tests (CATs), including head-up tilt test, increase the diagnostic yield. However, up one-fifth of examined patients have inconclusive CAT results. The aim present study was investigate predictive value history, clinical findings for unexplained after characterize...
Gestational weight gain (GWG) plays a crucial role in maternal and fetal health outcomes during pregnancy. Excessive is associated with various complications, emphasizing the importance of effective management strategies. Nutrition counseling has been proposed as promising intervention to optimize GWG improve infant outcomes. The aim this study was evaluate effectiveness nutrition for pregnant women experiencing unfavorable pregnancy, who were referred registered dietitian at centers Iran. A...
Background Vasovagal reflex is the most common form of syncope, but pathophysiological mechanisms that initiate are not well understood. We aimed to study supine and early orthostatic levels neurohormones involved in control circulatory homeostasis relation onset tilt‐induced vasovagal syncope (VVS). Methods Results A total 827 patients who were investigated for unexplained with head‐up tilt test (HUT) optional nitroglycerin provocation (Italian protocol) had blood samples collected while...
Abstract Background Non-communicable diseases are imposing a considerable burden on Iran. This study aims to assess the Return Investment (ROI) for implementation of (NCDs) prevention program in Methods Four disease groups including cardiovascular diseases, diabetes, cancer, and respiratory were included our ROI analysis. The followed four steps: 1) Estimating total economic NCDs using Cost-of-Illness approach. 2) costs implementing clinical preventive interventions an ingredient based...
Sodium benzoate and potassium sorbate are two common preservatives used in Iran, yet use of these doogh (Iranian dairy-based drink) is forbidden according to national standards. The aim this study was consider the presence by high-performance liquid chromatography with UV detection (HPLC-UV). method performed using a C18 column at 225 nm. mobile phase contained ammonium acetate buffer (pH = 4.2) acetonitrile (80:20 v/v). survey included 130 samples for identification quantification named...
Disease-related malnutrition is associated with adverse outcomes such as increased rates of morbidity and mortality, prolonged hospital stay, extra costs health care. This study was conducted to assess nutritional status among patients determine the risk factors for in Iran university f.Persian Nutritional Survey In Hospitals (PNSI) a cross-sectional that 20 hospitals across Iran. All age range 18 65 years, who were admitted or discharged, assessed by subjective global assessment (SGA).In...
Aim of this study was to explore whether differences in resting hemodynamic parameters may be associated with tilt test results unexplained syncope. We analyzed age, gender, systolic (SBP), diastolic blood pressure (DBP) and heart rate (HR) by merging three large databases patients considered likely vasovagal reflex etiology, comparing who had tilt-induced response those did not. Tilt-induced defined as spontaneous symptom reproduction characteristic hypotension bradycardia. Relationship...

A gas chromatographic procedure for analysis of sterols was developed to detect possible addition vegetable oils milk, yoghurt and butter samples. The method involved fat extraction, saponification, hexane silylation then by chromatography. sterol content 102 samples determined. Phytosterol higher than 5% total observed in four milk yoghurt. Principal component showed that there a direct relationship between the level phytosterols percentage described is accurate reliable enough be employed...
Detection of the cause diarrhoeal diseases is important for management outbreaks.This study investigated prevalence Shiga toxin-producing bacteria in stool samples patients with diarrhoea associated outbreaks foodborne illness Islamic Republic Iran.A total 532 and rectal swab from 70 sporadic during May 2014 to August 2015 were examined infection bacteria.

Background: Nationwide studies have focused only on prevalence of malnutrition in hospitalized children, while medical nu- trition therapies and assessing nutritional interventions is neglected.Methods: This research was conducted tertiary level children hospitals the NorthEastern region Iran for 1 year from 2016 to 2017. Five questions were included initial assessment form and, if there even one positive response, nutrition- al prescribed patients.Results: A total 65 aged ≥ 5 years two days...
Abstract Conditioned media (CM) from various cell types contain significant levels of paracrine factors. Recently, therapeutic properties CM derived stem cells have been revealed. Based on the fact that heart cancer is extremely rarely, we hypothesized obtained human pluripotent cell‐derived cardiomyocytes might inhibit growth and survival. To this end, lung line A549 along with foreskin fibroblasts (HFF) were treated serial concentrations cardiomyocyte (CCM) or fibroblast (FCM). We found...
<title>Abstract</title> Esophageal squamous cell carcinoma (ESCC) is one of the deadliest cancers worldwide. A decrease in global expression microRNAs (miRNAs) observed various types cancer, including esophageal cancer. It has been found that small molecule enoxacin serves as an RNA interference (RNAi) enhancer, increasing maturation rate cellular miRNAs. Here, we show significantly reduces growth characteristics ESCC lines. induces cycle arrest and apoptosis cells, leading to a clear number...
The prevalence of antibiotic resistance has been demonstrated in various food-borne pathogens. Beta-lactam antibiotics are among the first-line antimicrobials that normally administered case gastrointestinal infections. However, Escherichia coli (E. coli) and some other members Enterobacteriaceae have indicated broad against such thanks to extended-spectrum beta-lactamase (ESBL) enzymes. In this research, 216 stool samples screened for ESBL-producing E. coli, using phenotypic susceptibility...
Intestinal normal flora can become reservoirs of antibiotic resistance genes present among the strains responsible for nosocomial infections. It is suggested that gram negative intestinal bacterial have increased capacities to obtain and therefore act as main transfer other pathogenic bacteria. This study aimed compare fecal carriage clinically important markers more frequent members enterobacteriacae between nondiarrheal community associated diarrheal patients (control group) versus their...
