Abstract

Background: Epidemiological studies have reported positive, negative, U-shaped or J-shaped association between high blood pressure and cognitive function as well as dementia whereas other studies have not reported any significant association. The aim of this study was to examine the association between hypertension and cognitive impairment in the elderly residents of Kahrizak Charity Foundation (KCF).

Methods: This cross sectional study was done in Kahrizak Charity Foundation in suburban areas of Tehran, Iran during 2008. The data were collected over one week. Among the 850 elderly residents of the Foundation who were ≥ 65 years old, 185 individuals were chosen randomly. The Mini-Mental State Examination (MMSE) was completed for all. Mean of all blood pressure readings were recorded while anthropometric and biochemical measurements were performed.

Results: The findings indicated that in participants with cognitive impairment, systolic blood pressure, diastolic and mean blood pressures were higher than people with normal cognitive function but the differences were not significant statistically. The odds ratio of cognitive impairment in patients with and without hypertension was 1.52 and 1.58, respectively (P>0.05).

Conclusion: This study did not show any significant association between hypertension and cognitive impairment in the elderly residents of Kahrizak Charity Foundation.

Abstract
Background: Gender differences in scientometric indicators among medical faculty members in Iran was investigated.
Methods: The Research performance of the faculty at all universities and institutes of medical sciences in Iran was assessed using the Iranian Scientometric Information Database (ISID) on June 12, 2021. Selected variables in our study were name, gender, university, degree, academic rank, type of faculty, the total number of articles, the total number of citations, self-citation percentage, h-index, citation per article, international cooperation percentage, and the number of research collaborators. The Kruskal-Wallis test was used. The extracted data were analyzed using R v4.0.1 statistical software.
Results: A total of 21064 faculty members in 77 universities and institutes of medical sciences were registered in the ISID database, of which 12093 (57.4%) were men. Men faculty members outnumbered women in all academic ranks, except for the “instructor” rank (1134 female instructors against 835 male). In both sexes, most faculty members were assistant professors. There were more articles (346837 vs. 146024) and citations (5177060 vs. 1639246) by men than women. Among the 1789 faculty members with zero articles, 902 (50.4%) were men. One-hundred-and-fifty-four people were among ESI's top researchers' list, with a majority of men (124 people equal to 80.5%). The medians of all the scientometric indicators were higher in men than women. Men had a higher number of articles, the number of citations, h-index, citation per article, percentage of international articles, and co-authors, however, women had lower self-citations (1.56% vs. 2.51%). In all academic ranks, men had higher scientometric indicators. The only exception was the associate professors’ self-citation, in which women’s citations were higher than that of men (3.5 vs. 3.3). The highest mean h-index was in men with a Ph.D. in Pharmacy (13), men with a Ph.D. by Research (12) and women with a Ph.D. by Research (8.5), respectively.
Conclusion: Gender differences were evident in research performance in Iran. Women faculty members of medical sciences in Iran generally had lower scientometric indicators.

Abstract
Background: Cholangiocarcinoma is a cancer of the bile duct epithelium that originates from the bile ducts inside or outside the liver. Although this tumor is not common, its mortality rate is high. This tumor accounts for about 3% of all gastrointestinal malignancies. Many patients are being detected when the disease has spread. Evaluating risk factors affecting the incidence of cholangiocarcinoma is very important to avoid exposure to them. Therefore, this study was performed to evaluate the risk factors for cholangiocarcinoma in a population in Iran.
Methods: This was a descriptive cross-sectional study. It was performed on 276 patients with cholangiocarcinoma who had been referred to Firoozgar Hospital affiliated with the Iran University of Medical Sciences in Tehran from March 2020 to February 2021. Demographic information, family and personal history, social history (tobacco or drug use) and blood group of patients were extracted from their files. SPSS version 16 was used for data analysis. A P-value below 0.05 was considered statistically significant.
Results: The mean±SD age of patients was 65.97±13.07 years, of whom 65.6% were male and 34.4% were females. The most common site of cholangiocarcinoma was the distal part of the bile ducts and the most common blood group was O+. The main manifestations were jaundice and pruritus. Among the risk factors, the most common ones were smoking, high blood pressure, history of gallstones, opium use, history of cancer of other systems in the family, history of cholecystectomy and diabetes mellitus. While, the lowest prevalence of risk factors was related to heroin use, IBD, Gallbladder polyps, pancreatitis and alcohol consumption. None of the patients in our study had a history of viral hepatitis or PSC.
Conclusion: This was a cross-sectional study and only in the group of cholangiocarcinoma patients, therefore, larger prospective studies are recommended to examine underlying mechanisms of malignant transformation in the biliary tree.
