Inverse association between cigarette and water pipe smoking and hypertension in an elderly population in Iran: Bushehr elderly health programme.

The collected data in Bushehr Elderly Health (BEH) Program which had detailed the data on participants' smoking status and habits, was analysed to investigate the association between smoking of both water pipes and cigarettes and hypertension in an elderly population. Three thousand elderly men and women who participated in the baseline assessment of the BEH Program-a prospective population-based study being conducted in Bushehr, Iran-were selected randomly through a multistage, stratified cluster sampling method. Systolic and diastolic blood pressures were measured twice using a mercury sphygmomanometer, and researchers asked participants about medical history of hypertension as well as history of cigarette and water pipe smoking. Researchers used binary logistic regression models to assess the association of hypertension and smoking, and found an inverse, statistically significant association between current smoking and hypertension (odds ratio (OR)=0.50 (95% confidence interval (CI)=0.41, 0.60)). The association remained statistically significant after controlling for age, education and body mass index (OR=0.54 (95% CI=0.45, 0.66)). Findings were consistent for cigarette and water pipe smoking by sex (all ORs were inverse and statistically significant). Both cigarette and water pipe smoking were associated with reduced hypertension among older people, but the strength of association was different between men and women and also between cigarette and water pipe smoking. The reasons behind the association as well as the differences observed need to be investigated through more comprehensive, longitudinal studies

Occupancy detection in non-residential buildings – A survey and novel privacy preserved occupancy monitoring solution

Buildings use approximately 40% of global energy and are responsible for almost a third of the worldwide greenhouse gas emissions. They also utilise about 60% of the world’s electricity. In the last decade, stringent building regulations have led to significant improvements in the quality of the thermal characteristics of many building envelopes. However, similar considerations have not been paid to the number and activities of occupants in a building, which play an increasingly important role in energy consumption, optimisation processes, and indoor air quality. More than 50% of the energy consumption could be saved in Demand Controlled Ventilation (DCV) if accurate information about the number of occupants is readily available (Mysen et al., 2005). But due to privacy concerns, designing a precise occupancy sensing/counting system is a highly challenging task. While several studies count the number of occupants in rooms/zones for the optimisation of energy consumption, insufficient information is available on the comparison, analysis and pros and cons of these occupancy estimation techniques. This paper provides a review of occupancy measurement techniques and also discusses research trends and challenges. Additionally, a novel privacy preserved occupancy monitoring solution is also proposed in this paper. Security analyses of the proposed scheme reveal that the new occupancy monitoring system is privacy preserved compared to other traditional schemes

Effects of intravenous Semelil (ANGIPARS�) on diabetic foot ulcers healing: A multicenter clinical trial

Some diabetic foot ulcers, which are notoriously difficult to cure, are one of the most common health problems in diabetic patients .There are several surgical and medical options which already have been introduced for treatment of diabetic foot ulcers, so some patient will require amputation. The purpose of this study was to evaluate the efficacy of intravenous Semelil (ANGIPARS�), a naive herbal extract to accelerate healing of diabetic foot ulcers. A multi-centric randomized controlled trial was conducted to evaluate intravenous Semelil for healing of diabetic foot ulcers. Sixteen diabetic patients were treated with intravenous Semelil, and nine other patients were treated with placebo as control group. Both groups were otherwise treated by wound debridement and irrigation with normal saline solution, systemic antibiotic therapy and daily wound dressing. Before and after intervention, the foot ulcer surface area was measured, by digital photography, mapping and planimetry. After 4 weeks, the mean foot ulcer surface area decreased from 479.93±379.75 mm2 to 198.93±143.75 mm2 in the intervention group (p = 0.000) and from 766.22±960.50 mm2 to 689.11±846.74 mm2 in the control group (p = 0.076). Average wound closure in the treatment group was significantly greater than placebo group (64 vs. 25, p= 0.015). This herbal extract by intravenous rout in combination with conventional therapy is more effective than conventional therapy by itself probably without side effect. However, further studies are required in the future to confirm these results in larger population

Evidence gap and knowledge map of physical activity research in diabetes in Iran: A scoping review

Context: The important role of physical activity in the prevention and management of diabetes necessitates a review of current research to shed light on gaps in national diabetes guidelines. Evidence Acquisition: This scoping review was part of the Iran Diabetes Research Roadmap (IDRR) study. A systematic search was used based on the Arksey and O�Malley method consisting of six steps. The descriptive analysis was done with SPSS software. Additionally, VOS veiwer software was used to draw the knowledge map of the included studies. Results: There were 169 articles included from the beginning of 2015 to the end of 2019 in Iran. Aerobic and resistance exercises were types of physical activity with more number of articles. Most of the included clinical studies were randomized clinical trials and had a level of evidence two. Also, there was more interest in outcomes such as glycemic control and insulin sensitivity, metabolic syndrome, metabolism, and cardiovascular health. The network of co-authorship was drawn, and "controlled study", "male", and "rat" were the most frequent keywords. Conclusions: The number of Iranian diabetes researchers on physical activity is increasing, and the majority of clinical studies had a high level of evidence. With maintaining previous interests and investigations, there should be more emphasis on research in elderly and children age groups as evidence gap in Iran. Also, longitudinal cohort studies should be highlighted and Iranian researchers should be encouraged to participate in new topics of research worldwide.

Generalized or abdominal obesity: Which one better identifies cardiometabolic risk factors among children and adolescents? The CASPIAN III study

Objectives: We investigated the association of generalized and abdominal obesity with cardiometabolic risk factors in children and adolescents. Methods: Data were obtained from a surveillance system entitled CASPIAN-III study in school students aged 10-18 years in Iran. Data of subjects with normal body mass index (BMI) or above (BMI≥5th percentile) were analyzed. The associations of obesity with cardiometabolic risk factors were tested using logistic regression models. Results: In the sample of 4641 children and adolescents, overweight/obese children were more likely to have metabolic syndrome and cardiometabolic risk factors compared with their normal weight counterparts. Among these parameters, elevated TG had the strongest association with degree of obesity (overweight: OR1/42.28 95% CI 1.59-3.26; obesity: OR1/45.63 95% CI 4.27,7.43). Combined generalized and abdominal obesity increased the risk of high blood pressure, elevated triglyceride and total cholesterol. Conclusions: Combined type of generalized and abdominal obesity is a predictor of cardiometabolic risk factors. © The Author 2014

Study of some biological characteristics of golden grey mullet (Liza aurata) in Iranian Coastal waters of the Caspian Sea

During last 65 years the catch of mullets had increasing trends with some fluctuations in the Iranian coastal water of the Caspian Sea .In this period about 138 thousand tons of mullets have been caught. Mullet’s account for 35% of total catch annually .In recent years species composition of mullets has chanched in the Iranian coastal water of the Caspian Sea and catch composition of golden grey mullet increased from 76% in 1995 to 98% in 2006. In this survey some biological characteristics of golden grey mullet have been studied in Iranian coastal water of the Caspian Sea .Fish samples have been gathered from commercial catch of beach seine cooperatives monthly in Iranian coastal water of the Caspian Sea over 2006 and 2007. In the laboratory fishes have been measured biometrically and biological parameters have been calculated .Also catch statistics of mullets during 2006-2007 have been obtained and discussed. Results showed that the catch of mullets in beach seine cooperatives during 2006 and 2007 was 4181 and 3685 tons respectively that golden grey mullet contribute 99% and 98% of the catch composition of mullets respectively. Length range of golden grey mullet caught by beach seine cooperatives was 19-50.2 cm with mean length of 32.7 ± 6.4 (± SD) and weight range was 67-1475 gr with mean weight of 411 ± 255 gr. The age structure of this species was comprised 2-10 years old fish with mean age of 4.42 years old. In this survey totally the sex ratio of male: female of golden grey mullet was 356: 434 that was significant variation from equal sex ratio. Pick of the spawning in Guilan province was in October and in Mazandaran and Golestan provinces was in November. In October the proportion of spawning females declined from western area (Guilan province) towards eastern parts (Golestan province).The highest proportion of spawning females was in December in Golestan province. The highest GSI index value was observed in September and October and it was decreased in November and December and it was consistent during January till April. The mean absolute fecundity was 700881±429987 eggs with minimum and maximum fecundity of 200112 and 2282862 eggs respectively. The Lm 50% for female golden grey mullet was calculated as 33.6 cm

The Caspian Sea is an important source of water in terms of having valuable resources of sturgeon and bony fish is taken into consideration roach(Rutilus rutilus caspicus (L.)) is one of the most important commercial species in the southern coast of the Caspian Sea in Iran , the catch of this species has declined substantially in the last 10 years, The management and exploitation need of comprehensive review of its biology .This study as part of a comprehensive study of feeding , spawning and growth of this species.In this study, using samples caught in beach seine along the southern coast of the Caspian Sea coastal ( Iranian waters ) took place. The fork length and total weight ranged between 12.5 to29.5(cm) and 29 to293( grm),10.5 to23(cm) and17.2 to21(grm) in Golestan and Gilan Province respectively. The b value of the length-weight relationship ranged 3.02 to 3.25 and 3.28 to 3.75 for female and male, in Golestan and Gilan Province respectively. The age composition of the catch was from 1 to 4 year in both Province, there was one spawning peak and Fecundity variations were high and ranged 7260 to 231965 eggs. Average growth in length was described with the Von Bertalanffy growth model: L (t) = 30.94(1-exp (0.42(t-0.18) and L (t) = 20.49(1-exp (0.53(t-1). The percent of empty stomach and prey dominant evaluated during different seasons by specific formula. Result showed that gastropod, Polychaete worms and molluscs were dominated and specific food items respectively. Shrimp, fish, insects, zooplankton and clams were scare of prey

Association between psychosocial distress with cardio metabolic risk factors and liver enzymes in a nationally-representative sample of Iranian children and adolescents: The CASPIAN-III study

Background: The present study was designed to evaluate association of psychosocial distress with cardio metabolic risk factors and liver enzymes in Iranian children and adolescents.Method: This nationwide study was conducted as the third survey of the school-based surveillance system that was conducted among 5593 school students, 10-18 years in Iran. High triglyceride (TG), high fasting blood sugar (FBS), high total cholesterol (TC), high low-density lipoprotein cholesterol (LDL-C), low high-density lipoprotein cholesterol (HDL-C), hypertension (HTN), generalized obesity and abdominal obesity were considered as cardio metabolic risk factors and alanine transaminase (ALT) and aspartate aminotransferase (AST) were considered as liver enzymes. Data were analyzed using multiple logistic regression (MLR) analysis.Result: Psychosocial distress was detected in2027 (71.2) of boys and 1759 (63.3) of girls. Among boys, the mean of LDL, AST and DBP were higher and the mean FBS and HDL were lowering those with psychiatric distress than their other counterparts. Girls with psychosocial distress had significantly higher mean of HDL and FBS than those without psychiatric distress. Psychosocial distress significantly increased the odds of high LDL (OR = 2.36, 95CI 1.53, 3.64), high FBS (OR = 1.23, 95CI 1.02, 1.49) and low HDL (OR = 1.65, 95CI 1.41, 1.95).Conclusion: Psychosocial distress in adolescents is associated with increased risk of some cardio metabolic risk factors. © 2014 Qorbani et al.; licensee BioMed Central Ltd

Study on biology (age, feeding and, reproductive) of (Cyprinus carpio, Linnaeus 1758) in south coastal line Caspian Sea (Iranian waters)

The Caspian Sea is the biggest lacustrine water source. Common carp is very important commercially in south coastal line of Iranian Caspian Sea waters, especially in east coastal line, because eighty percent annual catch of this species has been caught in this area in particular. Despite the common carp importance and value in Iran, but there is a little information about its biology in natural system. This study is comprehensive research on reproduction, growth and feeding. The specimens were caught by beach seine net in coastal line of Iranian waters. The fork length ranged between 5.6 and 2866.2 g. The b value of the length-weight relationship ranged from 2.843 to 2.924 for female and male, respectively. The age composition of the specimens was from 1 to 11 year. The Gonadosomatic ratio (GSR) changed from 2 to 12. There were two peaks of GSR in April and December, so that the latter peak was much shorter than the first that. Fecundity variations were high and ranged 77448 to 430745 eggs. It observed linear significant correlation in fecundity- weight (r=0.98) and fecundity-length (r=0.88) relationships. Average growth in length was described with the Von Bertalanffy growth model: L (t) = 60.5(1-exp (0.19(t-0.65). The percent of empty stomach and prey dominant evaluated during different seasons by specific formula result showed that in Cyprinus carpio prey Molluscs was dominated and specific food items. Empty stomachs in winter and spring were higher and lower, respectively

Association of anthropometric measures with cardiovascular risk factors and metabolic syndrome in normal-weight children and adolescents: The CASPIAN III study

Objective: This nationwide study was conducted to determine the association of anthropometric measures with cardiovascular risk factors and metabolic syndrome (MetS) in Iranian normal-weight children and adolescents. Methods: We analyzed the data of 3,565 children and adolescents (50.3 boys), aged 10-18 years, with a normal BMI (5th-84th percentile) obtained from the third survey of 'Childhood and Adolescence Surveillance and Prevention of Adult Non-communicable Disease' (CASPIAN III) study. The diagnostic criteria for MetS were defined by the International Diabetes Federation consensus. Results: The prevalence of MetS for 10- to 13.9-year-old boys, 14- to 18-year-old boys, 10- to 13.9-year-old girls, and 14- to 18-year-old girls were 1.4, 2.8, 2.3, and 3.3, respectively. After adjustment for age and sex, each unit increase in BMI (within normal range) and waist circumference increased the odds of MetS from 6 to 72 and from 1 to 20, respectively. The dominant pattern of dyslipidemia among the participants was high triglycerides and low high-density lipoprotein cholesterol. Conclusion: This study complements recent research about the high frequency of metabolic risk factors among normal-weight individuals in the pediatric age group. © 2013 S. Karger GmbH, Freiburg
