Background: Vitamin D level can affect pulmonary function in patient who have chronic obstructive pulmonary disease (COPD). Objectives: There are few studies that assess this subject, so we investigate the relation of Vitamin D and COPD. Materials and Methods: A case-control study was conducted among the patients referred to the pulmonology clinic of Shahid Beheshti hospital of Hamadan, in which 68 of patients were assigned into the case group with COPD and 68 patients into the control group. Both groups were evaluated for respiratory differences as clinical or laboratory and the blood level of vitamin D was measured. Results: Of 136 evaluated participants with the mean age of 58.83 years old, 68 patients were studied as case group consisting of 2 females and 66 males. The results suggested that the serum level of vitamin D in COPD patients and control group patients were 22.22 ± 15.83 ng/mL and 27.47 ± 21.43 ng/mL, respectively. It was also found that there was a positive correlati...

BACKGROUND Few studies have focused on syndromic data to determine levels of alarm thresholds to detection of meningitis outbreaks. The purpose of this study was to determine threshold levels of meningitis outbreak in Hamadan Province, west of Iran. METHODS Data on both confirmed and suspected cases of meningitis (fever and neurological symptom) form 21 March 2010 to 20 March 2012 were used in Hamadan Province, Iran. Alarm threshold levels of meningitis outbreak were determined using four different methods including absolute values or standard method, relative increase, statistical cutoff points and upper control limit of exponentially weighted moving average (EWMA) algorithm. RESULTS Among 723 reported cases, 41 were diagnosed to have meningitis. Standard level of alarm thresholds for meningitis outbreak was determined as incidence of 5/100000 persons. Increasing 1.5 to two times in reported cases of suspected meningitis per week was known as the threshold levels according to relat...

Background: Among male sexual dysfunctions, erectile dysfunction and early ejaculation have the highest prevalence rates. Here, we tested the influence of lisdexamfetamine dimesylate (Vyas®) on early ejaculation. To this end, we performed a double-blind randomized clinical trial among males with early ejaculation. Methods: A total of 46 males with early ejaculation (mean age: 35.23 years) and in stable marital relationships with regular weekly penile–vaginal intercourse were randomly assigned either to the lisdexamfetamine dimesylate condition (30 mg) or to the placebo condition. Compounds were taken about six hours before intended penile–vaginal intercourse. At baseline and four weeks later at the end of the study, participants completed a series of self-rating questionnaires covering early ejaculation. Female partners also rated participants’ early ejaculation profile. Results: Compared to the placebo condition, dimensions of early ejaculation improved over time in the lisdexamfet...

For men, early ejaculation is a serious health concern. Here, we tested the influence of modafinil (Profinil®) on early ejaculation. To this end, we performed a double-blind randomized clinical trial among men with early ejaculation. A total of 46 men with early ejaculation (mean age: 37.35 years) and in stable marital relationships with regular weekly penile-vaginal intercourse were randomly assigned either to the modafinil (100 mg) or to the placebo condition. Compounds were taken about 4-6h before intended penile-vaginal intercourse. At baseline and four weeks later at the end of the study, participants completed a series of self-rating questionnaires covering early ejaculation. Female partners also rated their male partners' early ejaculation profile. Dimensions of early ejaculation improved over time, but only so in the modafinil condition, while no improvements were observed in the placebo condition. Among male adults in stable marital relationships with regular weekly penile-vaginal intercourse modafinil improved dimensions of early ejaculation, always compared to placebo. Given the strong effect of modafinil on cognitive-executive processes, it is conceivable, that modafinil acted both via physiological and cognitive-executive pathways.

BACKGROUND Occupational burnout is both a serious health concern at both public and individual levels. Treatment options are psychopharmacological, psychological and physical activity-related interventions. Here, we tested whether, compared to placebo, omega-3-polyunsaturated fatty acids (O3PUFAs) have a positive impact on burnout and morning cortisol secretion. METHOD A total of 43 individuals (mean age: 38.4 years, 76.7% females) took part in the present double-blind and placebo-controlled intervention. Participants were randomly assigned either to the O3PUFA or to the placebo condition. At baseline and again eight weeks later, participants completed the Maslach Burnout Inventory and collected morning saliva samples for analysis of the cortisol awakening response (CAR). RESULTS Emotional exhaustion and depersonalization decreased, and sense of personal accomplishment increased over time, but more so in the O3PUFA condition than in the placebo condition. Likewise, CAR decreased over time, but again more so in the O3PUFA condition than in the placebo condition. CONCLUSIONS The present pattern of results suggests that, compared to placebo, administration of daily omega-3-polyunsaturated fatty acids for eight consecutive weeks positively influences both psychological and physiological markers of occupational burnout.
