Estimating the Number of Genital Warts Cases in Bushehr City (Southwest Iran) in 2019 Using the Multiplier Method
Background: There is an information gap concerning the prevalence of genital warts infection in Iran. Objectives: The present study aimed to estimate the number of genital warts cases in the city of Bushehr using the multiplier method, which previously there was no accurate information. Methods: This 2019 cross-sectional study directly counted the number of cases of genital warts referred to private and public clinics in Bushehr City over a month (June). In July, a survey was conducted on the general population of the city in order to obtain information with reference to the number of people with a history of genital warts in the last month and to assess the patients who were referred to a healthcare center. We also interviewed physicians and midwives. Eventually, the number of genital warts cases calculated using the multiplier method (S = P1/P2 Ă— m formula). In order to accurately estimate the confidence interval, a Monte Carlo analysis was used in STATA version 14. Results: The number of genital warts cases referred to a provider in the investigated month, separated by general practitioners, dermatologists, gynecologists, midwives, urologists, and infectious diseases specialists, was estimated at 258, 195, 77, 48, 22, 22, and 9, respectively. Conclusions: The estimated number of genital warts cases in the study population was significantly higher than the reported cases for the investigated month by the Bushehr University of Medical Sciences Centers for Disease Control and Prevention (CDC). Understanding the true number of cases of genital warts can help policymakers in designing genital wart control and prevention programs for the general population and at-risk individuals.

Association of serum uric acid with high-sensitivity C-reactive protein in postmenopausal women
Objectives: To explore the independent correlation between serum uric acid and low-grade inflammation (measured by high-sensitivity C-reactive protein, hs-CRP) in postmenopausal women. Methods: A total of 378 healthy Iranian postmenopausal women were randomly selected in a population-based study. Circulating hs-CRP levels were measured by highly specific enzyme-linked immunosorbent assay method and an enzymatic calorimetric method was used to measure serum levels of uric acid. Pearson correlation coefficient, multiple linear regression and logistic regression models were used to analyze the association between uric acid and hs-CRP levels. Results: A statistically significant correlation was seen between serum levels of uric acid and log-transformed circulating hs-CRP (r = 0.25, p < 0.001). After adjustment for age and cardiovascular risk factors (according to NCEP ATP III criteria), circulating hs-CRP levels were significantly associated with serum uric acid levels (β = 0.20, p < 0.001). After adjustment for age and cardiovascular risk factors, hs-CRP levels ≥3 mg/l were significantly associated with higher uric acid levels (odds ratio =1.52, 95% confidence interval 1.18–1.96). Conclusion: Higher serum uric acid levels were positively and independently associated with circulating hs-CRP in healthy postmenopausal women.

Bushehr Elderly Health (BEH) Programme, phase I (cardiovascular system)
Purpose The main objective of the Bushehr Elderly Health Programme, in its first phase, is to investigate the prevalence of cardiovascular risk factors and their association with major adverse cardiovascular events. Participants Between March 2013 and October 2014, a total of 3000 men and women aged ≥60 years, residing in Bushehr, Iran, participated in this prospective cohort study (participation rate=90.2%). Findings to date Baseline data on risk factors, including demographic and socioeconomic status, smoking and medical history, were collected through a modified WHO MONICA questionnaire. Vital signs and anthropometric measures, including systolic and diastolic blood pressure, weight, height, and waist and hip circumference, were also measured. 12-lead electrocardiography and echocardiography were conducted on all participants, and total of 10 cc venous blood was taken, and sera was separated and stored at –80°C for possible future use. Preliminary data analyses showed a noticeably higher prevalence of risk factors among older women compared to that in men. Future plans Risk factor assessments will be repeated every 5 years, and the participants will be followed during the study to measure the occurrence of major adverse cardiac events. Moreover, the second phase, which includes investigation of bone health and cognition in the elderly, was started in September 2015. Data are available at the Persian Gulf Biomedical Research Institute, Bushehr University of Medical Sciences, Bushehr, Iran, for any collaboration.

Adiponectin as a Protective Factor Against the Progression Toward Type 2 Diabetes Mellitus in Postmenopausal Women
Serum adiponectin levels have been suggested to be predictors of type 2 diabetes mellitus in diverse populations. However, the relationship between circulating adiponectin levels and the risk of development of type 2 diabetes in postmenopausal women has not been investigated.A total of 382 healthy postmenopausal women who participated in a prospective cohort study were followed for 5.8 years. Type 2 diabetes mellitus was defined according to the criteria set out by the American Diabetes Association. Adiponectin, osteoprotegerin (OPG), and high-sensitivity C-reactive protein (hs-CRP) levels were measured using ELISA.Of 195 women who did not have diabetes at baseline and who were reexamined in the second phase of the study for diabetic status, 35 subjects (17.9%) developed type 2 diabetes mellitus during the 5.8 years follow-up period. The women with type 2 diabetes had lower adiponectin levels than the healthy postmenopausal women. Multiple regression analysis showed that, after adjustments were made for age, cardiovascular risk factors, OPG, and hs-CRP levels, higher baseline adiponectin levels were associated with a lower relative risk (RR) of having type 2 (RR=0.07, confidence interval [CI]: 0.01-0.66, P=0.021).Higher baseline adiponectin levels functioned as a predictor of a lower risk of developing type 2 diabetes mellitus among postmenopausal women during a 5.8 years follow-up study. Therefore, it is suggested that elevated adiponectin levels may offer protection against the development of type 2 diabetes mellitus after the menopause.

Chlamydia pneumoniae and Helicobacter pylori IgG seropositivities are not predictors of osteoporosis-associated bone loss: a prospective cohort study
The potential link between infection with Chlamydia pneumoniae or Helicobacter pylori and osteoporosis has not been investigated in population-based longitudinal studies. A total of 250 healthy postmenopausal women who participated in a prospective cohort study were evaluated for IgG antibodies directed against C. pneumoniae and H. p ylori, osteoprotegerin (OPG), the receptor activator of nuclear factor kappa B ligand (RANKL), CrossLaps, and osteocalcin. Bone mineral density (BMD) was measured at the femoral neck and lumbar spine at baseline and at follow-up 5.8 years later. There were no significant differences in age-adjusted bone turnover markers, OPG, RANKL, the RANKL/OPG ratio, and BMD between the C. p neumoniae and H. p ylori IgG seropositive and seronegative subjects (P > 0.05). Neither C. p neumoniae nor H. p ylori IgG seropositivity was associated with age-and body mass index-adjusted BMD at the femoral neck and lumbar spine or bone loss at the 5.8-year follow-up. In logistic regression analysis, neither C. p neumoniae nor H. p ylori IgG seropositivities predicted incident lumbar or spine osteoporosis 5.8 years later. In conclusion, neither C. p neumoniae nor H. p ylori IgG seropositivity was associated with bone turnover markers, the RANKL/OPG ratio, BMD, or bone loss in postmenopausal women. In addition, chronic infection with C. p neumoniae or H. p ylori did not predict incident osteoporosis among this group of women.

Molecular and parasitological study of cutaneous leishmaniasis in Bushehr province, southwest of the Islamic Republic of Iran: a cross-sectional study during 2009–2012
Cutaneous leishmaniasis (CL) is one of the most important parasitic disease in Iran. CL is distributed among more than half of 31 provinces of Iran. Studies on epidemiological aspects of the disease and Leishmania species identification among infected humans are necessary for providing a comprehensive prevention and control program thus; this descriptive cross-sectional study was conducted on all CL suspected patients who referred to Health Centers of Bushehr province from 2009 to 2012. Physical examinations were carried out in suspected individuals and CL cases were confirmed by microscopical examinations. Prepared slides from suspicious cases of CL were fixed with absolute methanol and stained by Giemsa 10 %. All the Giemsa-stained slides examined under a light microscope with high magnification (1,000×) and classified them based on grading of Leishmania parasites. DNA from each slide was extracted, separately. The ribosomal internal transcribed spacer 1 was amplified with specific primers and PCR products were digested by restrict enzymes (HaeIII), run them in 3 % gel agarose for electrophoresis and visualized on a UV transilluminator after staining with ethidium bromide. SPSS version 21 was used for data analyses. A total of 726 suspected CL cases were referred to Health Centers of Bushehr province from 2009 to 2012 and samples were only prepared from 188 of the patients whereas 43 (5.9 %) of them were microscopy positive. The most frequent of CL was observed in November (14 %) and December (12 %). The most distribution of CL lesions were observed on hands (32 %), feet (26 %), and face (21 %), respectively. The highest frequency of CL was observed in 1–9 years old (30 %). Altogether, 50 % of the patients showed one skin lesion and 2–10 skin lesions were occurred in the remained CL patients. Totally, 27 out of 43 (63 %) of the Giemsa stained slides were positive by PCR–RFLP assay because all the PCR–RFLP negative slides were prepared 3–4 years ago and kept without cover slip, and also observed scarce amastigotes during microscopy observations. Leishmania species were identified in 21 desirable slides which 14 of them were L. major and 7 of the remained isolates were identified L. tropica using PCR–RFLP.

Association of Pathogen Burden and Hypertension: The Persian Gulf Healthy Heart Study
Chronic infection with cytomegalovirus (CMV), Chlamydia pneumoniae, herpes simplex virus 1 (HSV-1), and Helicobacter pylori may contribute to essential hypertension. However, the evidence now available does not clarify whether the aggregate number of pathogens (pathogen burden) may be associated with hypertension. Sera from 1,754 men and women aged ≥25 years were analyzed for immunoglobulin G antibodies to C. pneumoniae, HSV-1, H. pylori, and CMV using enzyme-linked immunosorbent assay. The aggregate number of seropositives to the studied viral and bacterial agents was defined as pathogen burden. Hypertension was defined according to World Health Organization criteria. A total of 459 (26.3%) of the subjects had hypertension. In the hypertensive group, 4.2% had 0 or 1 pathogens present, 20.6% had 2, 43.2% had 3, and 32.1% had 4; in the normotensive group, 7.9% had 0 or 1, 28.4% had 2, 42.7% had 3, and 21.0% had 4. Of the 4 studied pathogens, H. pylori seropositivity showed a significant independent association with hypertension (odds ratio (OR) =1.37; 95% confidence interval (CI) =1.05–1.79; P = 0.02). In multiple logistic regression analyses, the pathogen burden did not show a significant independent association with hypertension. Coinfection with H. pylori and C. pneumoniae was significantly associated with hypertension compared with double seronegativity after adjustment for age, sex, chronic low-grade inflammation, and cardiovascular risk factors (OR = 1.68; 95% CI = 1.14–2.47; P = 0.008]. The pathogen burden was not associated with hypertension. However, coinfection with C. pneumoniae and H. pylori showed a significant association with essential hypertension, independent of cardiovascular risk factors and chronic low-grade inflammation.

A Pooled Analysis of Diagnostic Value of 99mTc-Ubiquicidin (UBI) Scintigraphy in Detection of an Infectious Process
Although the data are promising from limited studies with technetium-99m ubiquicidin (Tc-UBI) scintigraphy in detection of infection in humans, these studies have had a limited sample size. This study was conducted to provide a systematic review and meta-analysis of the reported diagnostic accuracy of Tc-UBI scintigraphy in detection of an infectious process. The PubMed/MEDLINE, Web of Science, EMBASE, and Google Scholar literature databases were systematically searched to find the relevant human studies on Tc-UBI scintigraphy. For each eligible study, the true-positive, false-positive, true-negative, and false-negative findings at Tc-UBI scintigraphy were recorded, and the overall statistical parameters were acquired. Ten studies carried out from 2004 to 2010 were included in the analysis. The pooled data sensitivity was 94.5 % and with a 95% confidence interval of 91.2%-96.8%. The pooled specificity was still as high as about 92.7%. The range of reported specificity was from 80% to 100%. The overall accuracy was 93.7% (95% CI: 91.2%-95.7%). The study demonstrated that Tc-UBI scintigraphy can be used to identify an infectious process with admirable accuracy in early views; however, further investigations are recommended.
