Abstract
Some studies suggest that childhood can affect some later outcomes. This cross-sectional study of the first phase of the Ardakan Cohort Study on Aging (ACSA) on 5,197 individuals examined the effects of childhood socioeconomic and health on aging well. Childhood socioeconomic status (SES) was measured using parents' education and self-expressed family's financial status. Quality of Life (SF-12), Satisfaction with Life Scale (SWLS), WHO well-being scale, and self-reported health questionnaire were used. All data, including childhood experiences, was collected at a single time point. Poor childhood health was associated with lower well-being, life satisfaction, and mental quality of life (OR: .53, p = .032, OR: 0.49, p = .019, and β: -3.51, p = .008, respectively). The family's financial status during childhood was associated with the mental and physical quality of life, satisfaction, well-being, and health (all p < .05). Fathers and mothers who had some level of education increased the odds of being healthy by 1.20 and 1.49 times, respectively. Childhood circumstances affect older adults' health and social conditions. Policies to improve childhood health and SES should be prioritized.

Abstract
BACKGROUND The global population is undergoing rapid aging, and older individuals are more susceptible to various health issues, including oral health problems. Despite the increasing attention given to healthy aging, oral health has often been overlooked in discussions related to health problems. This study aims to assess the oral health status of middle-aged and older adults in Iran. METHODS This cross-sectional study analyzed data from 4970 men and women aged 50 years and above, who participated in the Ardakan Cohort Study on Aging (ACSA) between 2020 and 2022. Trained personnel administered a questionnaire and conducted oral health examinations to determine the oral health status and oral hygiene behaviors of the participants. RESULTS The mean value (SD) of the total Decayed, Missing, and Filled Teeth (DMFT) index was 21.3 (10.7). Approximately 46% of all participants were completely edentulous (without natural teeth). Moreover, 58.5% of the total sample wore dentures, and the mean age (SD) when they started using dentures was 48.5 (20.7) years. About 71% of participants with natural teeth reported brushing their teeth at least once a day, while about 63% of denture wearers cleaned their dentures daily. In the sample, 28% of individuals had visited a dentist in the last year. The prevalence of difficulty in biting and chewing food among the participants was 48.2% and 44.6%, respectively. Additionally, nearly 68% of all samples reported experiencing at least one difficulty in daily functioning due to oral/dental conditions. The study identified cutoff points of seven (sensitivity = 56.8 and specificity = 77.5) and 10 (sensitivity = 72.1 and specificity = 71.1) missing teeth, indicating the presence of at least one problem in daily functioning due to oral/dental conditions in middle-aged and older adults, respectively. CONCLUSION The study reveals a high prevalence of edentulism and denture use among participants aged 50 years and above. The majority of samples reported difficulties in daily functioning due to oral and dental conditions, especially in biting and chewing food. These findings highlight the importance of proactive measures to address oral health issues in middle-aged and older adults, thereby enhancing their overall health and well-being.

Abstract
Background and Aims Data on mild cognitive impairment (MCI) in low- to middle-income countries are still being determined, despite the fact that most future older adults are expected to reside in these regions. This study aimed to investigate the prevalence and associated factors of MCI in Iran. Methods A cross-sectional study was conducted on 4938 community-dwelling subjects aged 50 years or above in the first wave of the Ardakan Cohort Study on Aging. MCI was evaluated using the Mini-Mental State Examination (MMSE) and the Abbreviated Mental Test Score (AMTS) in literate and illiterate individuals. The relationship between factors associated with the odds of MCI was assessed through logistic regression. Results The prevalence of MCI among all participants, the literates and illiterates, was 15.8%, 6.3%, and 36.4%, respectively. It was found that failure to accomplish any of the MMSE or AMTS items was significantly related to MCI (p < 0.001). Age ([odds ratio (OR): 1.05; p < 0.001 in the literates], [OR: 1.06; p < 0.001 in the illiterates]), sex (OR: 0.13; p < 0.001 in the illiterates), history of stroke ([OR: 2.86; p = 0.006 in the literates], [OR: 2.04; p = 0.045 in the illiterates]), and depression ([OR: 1.87; p < 0.001 in the literates], [OR: 1.41; p = 0.008 in the illiterates]) were significantly associated with MCI. Conclusion This study highlights the significant associations between age, education, depression, stroke, and MCI in Iranian participants. These findings emphasize the need for targeted interventions in low-literacy populations, mental health screening, and stroke prevention strategies to mitigate the burden of MCI and enhance cognitive health.

Abstract
Introduction The objective of this study was to assess the prevalence of falls, fear of falling (FOF), complications arising from falls, and identify possible sociodemographic and health-related factors associated with these outcomes among older adults. Methods This cross-sectional study was based on the first wave of the Ardakan Cohort Study on Aging (ACSA), which includes participants over 50 years of age residing in Ardakan, Iran. Fall history, number of fall events, FOF, hospitalizations, and fractures in the past 12 months were assessed through a face-to-face interview. Health-related factors were recorded on a self-expressed basis. Associations were assessed using multiple logistic regression. Results Among the 4,990 participants, fall history in the past 12 months was prevalent in 19.9%, with 10.1% reporting more than two fall events. Women (p < 0.001) and older participants (p< 0.001) had a higher prevalence. In females, 28.8% reported moderate to severe FOF, while 21% experienced disruptions in their daily activities as a result of this fear. The prevalence of fractures following falls was 5.1% in males and 8.6% in females. After adjusting for confounding factors, FOF (OR: 1.59, 95% CI: 1.33-1.91, p<0.001), imbalance (OR: 2.45, 95% CI: 1.68-3.58, p<0.001), urinary incontinence (OR: 1.44, 95% CI: 1.04-1.9, p=0.025), cognitive impairment (OR: 1.21, 95% CI: 1.01-1.46, p=0.049), vertigo or dizziness (OR: 1.39, 95% CI: 1.15-1.68, p<0.001), osteoporosis (OR: 1.24, 95% CI: 1.03-1.50, p=0.023), osteoarthritis (OR: 1.33, 95% CI: 1.13-1.56, p=0.001), depression (OR: 1.30, 95% CI: 1.06-1.60, p=0.010), and Central Nervous System (CNS)-affecting diseases (OR: 1.99, 95% CI: 1.33-2.97, p=0.001) were found to have positive associations with falls. Conclusion This study showed that about one-fifth of those over 50 in Iran have experienced at least one fall within a year. Self-expressed imbalance, FOF, and urinary incontinence were the most prominent risk factors. Due to resulting in hospitalization and fractures, falls also lead to fear of falling and the associated limitation of activities.

Abstract
BACKGROUND AND AIM Social factors play a crucial role in the quality of life of + 50 adults. This study aimed to investigate the association between social support, depression, and loneliness and the health-related quality of life in + 50 adults of Ardakan. METHODS This was a cross-sectional study from the first phase of Ardakan Cohort Study on Aging (ACSA) in 2019. Health-Related Quality of Life (HRQoL, SF-16), Duke Social Support Index (DSSI), and Center for Epidemiologic Studies Depression Scale (CES-D10) were used to assess the variables of interest. Multivariable linear regression was used to model the associated factors with the score of the SF-16 tool in two dimensions; physical (PCS) and mental (MCS). FINDINGS A total of 5197 over 50 years individuals included in this study; The mean age was 62.2 ± 7.3 years old, and 52% were male. The mean score for PCS and MCS subscales was 45.6 (95% CI 45.4 to 45.9) and 49.3 (95% CI 49.0 to 49.5), respectively. Adjusted for other variables, having less feeling level of loneliness, and not having depressive symptoms were related to better PCS and MCS scores. CONCLUSION The HRQoL for the mental aspect of HRQoL was better than the physical in elder populations. Also, much more focus should be paid to older adults who experience inadequate social support, higher levels of loneliness, and depressive symptoms.

Abstract
BACKGROUND Sleep is a necessary physiological process that affects health. The current study aimed to evaluate sleep quality (SQ) and the related factors in Iranian community-dwelling adults. Study Design: A cross-sectional study. Method: Population-based cross-sectional data from the first wave of the Ardakan cohort study on aging (ACSA) were analyzed. The analytical sample consisted of 5197 community-dwelling adults aged≥50. All data were collected by trained staff. Pittsburgh Sleep Quality Index (PSQI) scores were used to measure SQ. Univariable and multivariable logistic regression were used to identify predictors of SQ. RESULTS The mean age of the participants was 62.22±7.7 years, and 51.8% were female. About threequarters of them (76.36%) were found to have poor SQ (PSQI score≥5). Multivariable logistic regression analysis revealed a relationship between SQ and gender, education, work, and financial level. Furthermore, SQ was found to be associated with self-reported health and physical activity. Regarding comorbidity, SQ had a significant relationship with cardiovascular diseases, musculoskeletal diseases, depression, and anxiety (P<0.05). CONCLUSION The prevalence of poor SQ was high in these community-dwelling adults in Iran. These findings highlight the importance of intervention programs for sleep hygiene education and screening for middle-aged and older adults.

Abstract
OBJECTIVES The purpose of this study was to investigate the analgesic effects of duloxetine, specifically on postoperative pain, opioid consumption, and related side effects following total hip or knee arthroplasty. METHODS In this systematic review and meta-analysis, Medline, Cochrane, EMBASE, Scopus, and Web of Science were searched until November 2022 for studies which compared duloxetine with placebo when added to routine pain management protocols. Individual study risk of bias assessment was conducted based on Cochrane risk of bias tool 2. Random effect model meta-analysis was done on mean differences, to evaluate the outcomes. RESULTS Nine randomized clinical trials (RCT) were included in the final analysis, totaling 806 patients. Duloxetine reduced opioid consumption (oral morphine milligram equivalents) on postoperative days (POD) 2 (mean difference (MD): -14.35, P = .02), POD 3 (MD: -13.6, P < .001), POD 7 (MD: -7.81, P < .001), and POD 14 (MD: -12.72, P < .001). Duloxetine decreased pain with activity on POD 1, 3, 7, 14, 90 (All P < .05), and pain at rest on POD 2, 3, 7, 14, and 90 (all P < .05). There was no significant difference in the prevalence of the side effects, except for increased risk of somnolence/drowsiness (risk ratio: 1.87, P = .007). CONCLUSION Current evidence shows low to moderate opioid sparing effects of perioperative duloxetine and a statistically but not clinically significant reduction in pain scores. Patients treated with duloxetine had an increased risk for somnolence and drowsiness.

Abstract
BACKGROUND The association of obesity with left ventricular (LV) diastolic dysfunction is fully understood, but there are few investigations regarding its effect on LV systolic function in the absence of other risk factors. This study aimed to identify the global longitudinal strain (GLS) changes in isolated overweight and obese people in the absence of other risk factors. METHODS A total of 120 individuals, including 60 obese, 30 overweight, and 30 healthy controls with no underlying disease and no history of hypertension, diabetes, CAD, or CKD were included in the study. Echocardiographic findings were measured, including apical 2-, 3- and 4-chamber GLS, GLS total, LV diameter, interventricular septum thickness, and PAP. These findings were then compared between the three groups (obese, overweight, and normal controls). RESULTS Analyses showed that LV diameter in healthy controls was significantly lower compared to overweight (p = 0.02) and obese (p < 0.0001) participants. Also, the interventricular septal thickness was significantly increased in overweight (p = 0.007) and obese (p < 0.0001) individuals compared to healthy controls. The mean and standard deviation (Mean ± SD) of total GLS values were - 22.29% ± 1.89% for normal weight, -22.09% ± 1.91% for overweight, and -19.88% ± 2.34% for obese individuals. The total GLS of obese participants was significantly lower than overweight and normal controls (p < 0.0001). It was observed that the GLS values were significantly lower in people with BMI higher than 40. The mean ± SD of total GLS values were -20.68% (1.84%) for BMI ≤ 40 patients and -18.51% (2.52%) for BMI > 40 patients. CONCLUSION Data revealed that all GLS values had a moderately strong correlation with BMI values. Also, subclinical LV dysfunction was detected in overweight and obese subjects.

Abstract
Purpose: To determine the global prevalence and common causes of visual impairment (VI) and blindness in children. Methods: In this meta-analysis, a structured search strategy was applied to search electronic databases including PubMed, Scopus, and Web of Science, as well as the list of references in the selected articles to identify all population-based cross-sectional studies that concerned the prevalence of VI and blindness in populations under 20 years of age up to January 2018, regardless of the publication date and language, gender, region of residence, or race. VI was reported based on presenting visual acuity (PVA), uncorrected visual acuity (UCVA), and best corrected visual acuity (BCVA) of equal to 20/60 or worse in the better eye. Blindness was reported as visual acuity worse than 20/400 in the better eye. Results: In the present study, 5711 articles were identified, and the final analyses were done on 80 articles including 769,720 people from twenty-eight different countries. The prevalence of VI based on UCVA was 7.26% (95% confidence interval [CI]: 4.34%–10.19%), PVA was 3.82% (95% CI: 2.06%–5.57%), BCVA was 1.67% (95% CI 0.97%–2.37%), and blindness was 0.17% (95% CI: 0.13%–0.21%). Refractive errors were the most common cause of VI in the subjects of selected articles (77.20% [95% CI: 73.40%–81.00%]). The prevalence of amblyopia was 7.60% (95% CI: 05.60%–09.10%) and congenital cataract was 0.60% (95% CI: 0.3%–0.9%). Conclusion: Despite differences in the definition of VI and blindness, based on PVA, 3.82%, and based on BCVA, 1.67% of the examined samples suffer from VI.

Abstract
Background: The genus Abbreviata (Spirurida: Physalopteridea) currently contains 47 species. Physalopteridae nematodes infect a large number of vertebrates, including mammals, birds, reptiles and amphibians. The current study is a report of the first morphological and molecular identification of A. kazakhstanica (Spirurida: Physalopteridea) in Pseudopus apodus in Iran. Methods: Eleven road-killed P. apodus, were collected from, Iran during 2016–2018. The nematodes were isolated from stomach. After morphological study, the genomic DNA of the parasites was extracted using CTAB method. The DNA was used for PCR amplification of cytochrome c oxidase subunit I (cox1). The PCR products were sequenced, the sequence data were analyzed and multiple alignments were conducted using the Clustal Omega. Results: After detailed microscopic examination, the A. kazakhstanica was identified. The cox1 sequences confirmed the species of helminth. The new sequences of A. kazakhstanica were submitted to GenBank under the accession number MK578751-2. Conclusion: Regarding the limited data on parasitological status of Iranian reptiles, more specific and comprehensive investigations are needed to identify the parasitic fauna.

Abstract
This meta-analysis aimed to examine the association between the mode of delivery and dyspareunia worldwide. Epidemiologic studies evaluating the link between the mode of delivery and dyspareunia (published up to July 2019) were included in this research. These studies were selected by searching several databases such as MEDLINE, ClinicalTraial.gov, PubMed, Web of Science, Scopus and Google Scholar and considering the list of selected articles extracted from references. Then, meta-analyses, subgroup analyses and meta-regressions of the studies were conducted to evaluate the association between the mode of delivery and dyspareunia. In this study, 23 out of 1099 articles were identified and used in the final analysis. Dyspareunia differed according to the mode of delivery although this difference was not statistically significant. In terms of the mode of delivery, a difference was found between instrumental vaginal delivery and caesarean section, but it was not significant. It seems that more studies with a larger sample size should be considered to determine the difference.

Abstract
PURPOSE The purpose of the present study was to evaluate the prevalence of refractive errors in the Middle East region. METHODS In this meta-analysis, a structured strategy was applied to search databases PubMed, Web of Science, Scopus, and Google Scholar, databases as well as the reference lists of the selected articles to identify cross-sectional studies assessing the prevalence of refractive errors in the Middle East region until September 2019. The outcome measure was the prevalence of refractive errors, including myopia, hyperopia, and astigmatism, in two age groups of ≤ 15 years and > 15 years. The study results were combined using a random effects model at a confidence level of 95%. RESULTS The prevalence of myopia, hyperopia, and astigmatism was 4% (95% CI 4, 5), 8% (95% CI 6, 10), and 15% (95% CI 10, 19) in people less than or equal to 15 years and 30% (95% CI 25, 34), 21% (95% CI 15, 28), and 24% (95% CI 16, 31) in subjects over 15 years, respectively. The prevalence of myopia, hyperopia, and astigmatism was 3.5%, 12.4%, and 9.0% in male and 4.2%, 13.1%, and 9.9% in female subjects aged ≤ 15 years, respectively. In subjects aged > 15 years, the prevalence was 31.7%, 14.5%, and 31.5% in males and 31.9%, 11.2%, and 31% in females, respectively. CONCLUSION The prevalence of hyperopia is relatively high in Middle Eastern children, while the prevalence of myopia is higher in adults in this region. It seems that astigmatism is not a serious refractive problem in this region compared to the rest of the world.

Abstract
Background The main causes of the progression of non-alcoholic fatty liver disease (NAFLD) are enhanced levels of reactive oxygen species and lipid peroxidation products. Therefore, the usage of antioxidant agents for the prevention and remedy of this disorder was recommended. Curcumin is proposed to treat NAFLD due to its high antioxidative activity. The aim of this study was to examine the effect of curcumin with piperine supplementation on oxidative stress in subjects with NAFLD. Methods In this double-blind, placebo-controlled trial, 55 subjects were randomly divided into two groups (curcumin with piperine and placebo). The participants received administrations of curcumin (500 mg) in combination with piperine (5 mg) and placebo daily for 8 weeks. Oxidative stress was assessed by measuring serum pro-oxidant and antioxidant balance (PAB) assay before and after the intervention. Results The serum PAB values did not significantly change between the treatment group vs. age and gender-matched placebo group after 8 weeks of supplementation. Also, curcumin in combination with piperine did not show a significant decrease (p = 0.06) in PAB levels compared to baseline. Conclusions The present study demonstrated that a dose of curcumin, co-supplied with piperine might be less than a dose in which curcumin can significantly decrease PAB values in these patients.

Abstract
BACKGROUND Tuberculosis (TB) despite being preventive and treatable still imposes a huge burden of morbidity and mortality in developing and developed countries. We aimed to investigate the spatial and geographical distribution of TB in Hamadan province during 1992-2013. MATERIALS AND METHODS This cross-sectional study was performed in Hamadan province, West of Iran using the surveillance database. We examined the trend for incidence rates of all TB forms including Smear Positive Pulmonary TB (SPPT), Smear Negative Pulmonary TB (SNPT) and Extra pulmonary TB (EPT) per 100,000 populations. Poisson regression model was used to estimate the standardized rates for incidence rate of all types of TB per each county. RESULTS In this study 3,602 TB patients including 1,359 SPPT, 987 SNPT, and 1,256 EPT were included during 1992-2013. Trend of all types of TB decreased from 1992 to 2013. The Average Annual Percent change (AAPC) for all types of TB was significantly (P<0.05) decreased, AAPC= -6.4 (95% CIs: -10.7, -1.9). Among SPPT, SNPT, and EPT incidence rates, the maximum change was related to SNPT (-11.6; 95% CIs: -24.2, 3), while it was -1.4 (-8.7, 6.4) for SPPT and -5.8 (-11.4, 0.1) for EPT. CONCLUSION Our results showed that the incidence of TB in Hamadan province during a 22-year period has decreased 6.4% on average, somehow higher than the national average. Furthermore, our study showed that the risk of extra-pulmonary occurrence in western parts of the province is higher than others parts.

Abstract
Hypertension is becoming a global epidemic for both rural and urban populations; it is a major public health challenge in Iran. Fluoride can be a risk factor for hypertension. Cross-sectional analysis was conducted in two study areas to assess the relation of fluoride with blood pressure prevalence, BMI, waist circumference, and waist-to-hip ratio (WHR) among different age groups in both sexes. The mean value of fluoride concentration in the drinking water from the four study villages varied from 0.68 to 10.30 mg/L. The overall prevalence of HTN and prehypertension in all subjects was 40.7%. The prevalence of isolated systolic hypertension, isolated diastolic hypertension, systolic-diastolic hypertension, and prehypertension in the total sample population was 1.15, 0.28, 9.53, and 29.76%, respectively. The odd ratio of hypertension in residents who drank water with high fluoride levels was higher than that in residents who drank water with lower level of fluoride (OR 2.3, 1.03-5.14). Logistic regression results showed that age (P < 0.001), sex (P = 0.018), BMI (P = 0.015), and the fluoride level in drinking water (P = 0.041) had a significant relationship with increased blood pressure. There were no statistically significant correlations between fluoride and BMI, hip circumference, and waist to hip ratio (WHR). The findings of this study are important for health care personnel and policymakers.

Abstract
AIM N-3 PUFAs can potentially influence levels of inflammatory and non-inflammatory adipokines. Given the contradictory effects of n-3 PUFAs on serum levels of adipokines in type 2 diabetes, we conducted a systematic review and meta-analysis study of randomized placebo-controlled clinical trials that examined the effects of n-3 PUFAs on serum levels of leptin and adiponectin in patients with type 2 diabetes. METHODS The electronic databases, without regard to language restrictions including PubMed/Medline, Google Scholar, SCOPUS and ISI Web of Science until August 2017, were used to identify randomized controlled trials that assessed the effect of n-3 PUFAs on serum leptin and adiponectin concentrations in type 2 diabetes. Outcomes were extracted based on the mean ± SD as effect size at baseline and end of the intervention. Between-study heterogeneity was evaluated by the I2 estimates and their 95% CIs. Funnel plot asymmetry was used to investigate the existence of publication bias. Stata software and Review Manager were used for statistical data analysis. RESULTS Data from 10 eligible articles involved 494 subjects with type 2 diabetes mellitus (intervention groups = 254 and control groups = 240), with age between 44 and 70 years, treated with doses of 0.52-7.4 g/day n-3 PUFAs. Adiponectin concentration nonsignificantly increased by a MD = 0.17 µg/mL (95% CI - 0.11, 0.44). Also, leptin concentration nonsignificantly reduced by a MD = - 0.31 ng/mL (95% CI - 0.69, 0.07). CONCLUSION Plant and marine sources of n-3 PUFAs can modify serum leptin and adiponectin levels by increasing adiponectin and decreasing leptin levels in patients with type 2 diabetes. Due to some limitations in this study, further studies are needed to reach a definitive conclusion about the effect of n-3 PUFAs on the levels of leptin and adiponectin in T2DM.

Abstract
Background Despite our awareness of the significant effect of smoking on multiple sclerosis (MS), there was a serious lack of information about the effect of different types of smoking habit on MS as well as the dose-response relationship between smoking and MS, but this gap was addressed by this meta-analysis. Methods Major electronic databases, including PubMed, Web of Science and Scopus were searched until July 2015. Epidemiological studies addressing the association between smoking and MS were enrolled. The heterogeneity across studies was investigated by Q-test and I2 statistic. The probability of publication bias was explored using Begg's and Egger's tests. The results were expressed as odds ratio (OR) with 95% confidence intervals (CI) using a random effects model. Results We identified a total of 10 687 references and included 34 studies involving 623 852 participants. Compared with nonsmokers, the OR estimate of MS was 1.46 (1.33, 1.59) among ever smokers, 1.57 (1.34, 1.80) among current smokers, 1.36 (1.27, 1.46) among ex-smokers and 1.12 (0.87, 1.36) among passive smokers. In addition, analyzing the effect of cigarette pack-year on MS indicated that the OR estimate of MS was 1.34 (1.06, 1.61) for 1-5 cigarette pack-years, 1.56 (1.15, 1.97) for 6-10 cigarette pack-years, 1.74 (1.16, 2.33) for 11-15 cigarette pack-years and 1.46 (0.49, 2.43) for more than 15 cigarette pack-years. Conclusions Smoking habits are significantly associated with MS, although the association is not very strong. However, there is a dose-response relationship between the smoking habits and MS.

Abstract
Background A 25% relative reduction in the prevalence of hypertension is a global target. This meta-analysis estimated the effect of excess weight loss on hypertension. Methods We searched PubMed, Web of Science and Scopus until January 2016. We included prospective cohort studies addressing the association between overweight/obesity and hypertension. We expressed the strength of association using risk ratio and the excess risk using attributable risk fraction with 95% CI based on the random-effects model. Results We found 7617 references and included 10 studies with 173 828 participants. Compared with normal weight, the risk ratio of hypertension was 1.52 (1.37, 1.67; 9 studies, I2 = 82.4%) for overweight and 2.17 (1.84, 2.50; 9 studies, I2 = 88.9%) for obesity. The excess risk of hypertension attributable to overweight was 32% (24%, 40%; 8 studies, I2 = 85.5%) and that attributable to obesity was 47% (40%, 54%; 8 studies, I2 = 88.2%). That means, excess weight loss may reduce the risk of hypertension by between 24% and 40% in people who are overweight and by between 40% and 54% in people who are obese. Conclusions Excess weight loss is a vital strategy for controlling hypertension and is sufficient for achieving the global target, particularly if it is accompanied with other preventive measures.

Abstract
IMPORTANCE Increased dietary potassium intake is thought to be associated with low blood pressure (BP). Whether potassium supplementation may be used as an antihypertensive agent is a question that should be answered. OBJECTIVE To assess the effect of oral potassium supplementation on blood pressure in patients with primary hypertension. SEARCH METHODS We searched Medline, Web of Science, Scopus, Cochrane Central Register of Controlled Trials until October 2016. We also screened reference lists of articles and previous reviews. We applied no language restrictions. SELECTION CRITERIA We included randomized placebo-controlled clinical trials addressing the effect of potassium supplementation on primary hypertension for a minimum of 4 weeks. DATA COLLECTION AND ANALYSIS We extracted data on systolic and diastolic BP (SBP and DBP) at the final follow-up. We explored the heterogeneity across studies using Cochran's test and I2 statistic and assessed the probability of publication bias using Begg's and Egger's tests. We reported the mean difference (MD) of SBP and DBP in a random-effects model. RESULTS We found a total of 9059 articles and included 23 trials with 1213 participants. Compared to placebo, potassium supplementation resulted in modest but significant reductions in both SBP (MD -4.25 mmHg; 95% CI: -5.96 to -2.53; I2 = 41%) and DBP (MD -2.53 mmHg; 95% CI: -4.05 to -1.02; I2 = 65%). According to the change-score analysis, based on 8 out of 23 trials, compared to baseline, the mean changes in SBP (MD -8.89 mmHg; 95% CI: -13.67 to -4.11) and DBP (MD -6.42 mmHg; 95% CI: -10.99 to -1.84) was significantly higher in the intervention group than the control group. CONCLUSIONS Our findings indicated that potassium supplementation is a safe medication with no important adverse effects that has a modest but significant impact BP and may be recommended as an adjuvant antihypertensive agent for patients with essential hypertension.

Abstract
BACKGROUND The life expectancy of patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) reported by several epidemiological studies is inconsistent. This meta-analysis was conducted to estimate the survival rate from HIV diagnosis to AIDS onset and from AIDS onset to death. METHODS The electronic databases PubMed, Web of Science and Scopus were searched to February 2016. In addition, the reference lists of included studies were checked to identify further references, and the database of the International AIDS Society was also searched. Cohort studies addressing the survival rate in patients diagnosed with HIV/AIDS were included in this meta-analysis. The outcomes of interest were the survival rate of patients diagnosed with HIV progressing to AIDS, and the survival rate of patients with AIDS dying from AIDS-related causes with or without highly active antiretroviral therapy (HAART). The survival rate (P) was estimated with 95% confidence intervals based on random-effects models. RESULTS In total, 27,862 references were identified, and 57 studies involving 294,662 participants were included in this meta-analysis. Two, 4-, 6-, 8-, 10- and 12-year survival probabilities of progression from HIV diagnosis to AIDS onset were estimated to be 82%, 72%, 64%, 57%, 26% and 19%, respectively. Two, 4-, 6-, 8- and 10-year survival probabilities of progression from AIDS onset to AIDS-related death in patients who received HAART were estimated to be 87%, 86%, 78%, 78%, and 61%, respectively, and 2-, 4- and 6-year survival probabilities of progression from AIDS onset to AIDS-related death in patients who did not receive HAART were estimated to be 48%, 26% and 18%, respectively. Evidence of considerable heterogeneity was found. The majority of the studies had a moderate to high risk of bias. CONCLUSION The majority of HIV-positive patients progress to AIDS within the first decade of diagnosis. Most patients who receive HAART will survive for >10 years after the onset of AIDS, whereas the majority of the patients who do not receive HAART die within 2 years of the onset of AIDS.

Abstract
BACKGROUND Antibodies against hepatitis B surface antigen (HBsAg) wane over time following hepatitis B immunisation; hence, it is unclear whether people vaccinated in three-dose or four-dose schedules of the hepatitis B vaccine are still immune when the hepatitis B surface antibody (anti-HBs) level in their body is undetectable, or lower than the level usually considered protective. This question may potentially be answered indirectly by measuring the anamnestic immune response to a booster dose of vaccine. The term 'booster' (or revaccination) refers to an additional dose of hepatitis B vaccine (HBV) given some time post-primary vaccination to induce immune memory and improve protection against hepatitis B virus (HBV) infection. OBJECTIVES To assess the benefits and harms of booster dose hepatitis B vaccination, more than five years after the primary vaccination, for preventing HBV infection in healthy individuals previously vaccinated with the hepatitis B vaccine, and with hepatitis B surface antibody (anti-HBs) levels below 10 mIU/mL. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index Expanded, conference databases, and reference lists of articles to January 2016. We also contacted authors of articles. In addition, we searched ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform for ongoing trials (May 2016). SELECTION CRITERIA Randomised clinical trials addressing anamnestic immune response to a booster dose of hepatitis B vaccine, more than five years after the primary vaccination, in apparently healthy participants, vaccinated in a three-dose or four-dose schedule of the hepatitis B vaccine during the primary vaccination, without receiving an additional dose or immunoglobulin. DATA COLLECTION AND ANALYSIS Both review authors decided if the identified studies met the inclusion criteria or not. Primary outcomes included the proportion of participants with anamnestic immune response in non-protected participants and signs of HBV infection. Secondary outcomes were the proportion of participants that developed local and systemic adverse events following a booster dose injection. We planned to report the weighted proportion with 95% confidence intervals (CIs). MAIN RESULTS There were no eligible randomised clinical trials fulfilling the inclusion criteria of this review. AUTHORS' CONCLUSIONS We were unable to include any randomised clinical trials on the topic; only randomised clinical trials will be able to provide an answer as to whether a booster dose vaccination is able to protect against hepatitis B infection.

Abstract
One species of Babesia was identified on the blood smear of 20 different naturally infected sheep in the Northwest of Iran. It was polymorphic, including double pyriform with acute or obtuse angle, single pyriform, and ring form. The size of typical paired pyriforms with acute angle was 2.7 x 0.4 microm (n=10) and with obtuse angle was 3.5 x 0.6 microm (n=10). Although the morphological and biometrical parameters resembled the Babesia motasi, the results of seminested polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism using primers specific for small subunit of 18S rRNA confirmed this species as Babesia ovis. Furthermore, the sequence analysis of hypervariable region of small subunit of 18S rRNA revealed the corresponding sequences for B. ovis as well. Experimental infection of healthy lambs with the morphological larger B. ovis showed a milder clinical signs compared to the small one.

Abstract
The tick-borne diseases of livestock constitute a complex of several diseases with different etiological agents, such as protozoa, rickettsia, bacteria, and viruses. One problem discussed in protozoan infection is the determination and characterization of the transmitter agent. Because many analyses were performed with the salivary gland smears using the methyl-green-pyronin staining method or the Feulgen staining method, the transfer vector remains unanswered in some cases. The aim of this study is to recognize Babesia ovis in the salivary gland of Rhipicephalus spp. using polymerase chain reaction (PCR). Deoxyribonucleic acid (DNA) was isolated from 269 salivary gland of Rhipicephalus spp. (108 R. bursa, 87 R. turanicus, 74 R. sanguineus) collected from sheep with suspected to babesiosis. The isolated DNA was then analyzed with the primers derived from the hypervariable region V4 of 18S ribosomal ribonucleic acid (rRNA) of the Babesia species. For the specificity of the PCR product and discriminating from Babesia motasi and Babesia crassa, nested PCR and restriction fragment length polymorphism was performed. As positive control for the DNA extraction procedure, the DNA was analyzed with the common primers designed from the 18S rRNA of the Ticks (Rhipicephalus, Hyalomma, Haemophysalis, Dermacentor, Ixodes, Boophilus). B. ovis was detected in salivary gland of 18.5% R. bursa, 9.1% R .turanicus, and 8.1% R. sanguineus, respectively.
