Speed is a quality measurement for travel, since it is related to traffic, safety, time, and economics. The speed limit on selected freeways in Kansas changed from 70 mph to 75 mph in the summer of 2011. In this study, the driver’s speed selection behavior was analyzed by considering average speed and 85th percentile speed in the before and after periods. Data from Automatic Traffic Recorders (ATRs) on the sections affected by speed limit increase and sections with no speed limit increase were analyzed. The t-test was applied to investigate if there was any significant difference in the speed of drivers on both treated and control sections. The Kolmogorov-Smirnov (K-S) test was also conducted to see if the distribution of speed data in the before period was different than after the period. The results showed that for the majority of the sections affected by speed limit change, there was a statistically significant difference in the 85th percentile speed of drivers during after period. Additionally, the K-S test results showed that the distribution of speed data in the before period was different than after the period for the majority of treated sections. The results indicated how drivers’ behavior was influenced by the speed limit increase.

Postpartum stress is very likely to take place as there are fluctuations in terms of feelings, pressure, anxiety, and guilt that may result in hypogalactia without proper treatment. Hypogalactia itself is an issue breastfeeding mothers face that may stall toddlers’ growth, and hence, the future of a nation. This research aims to lower stress levels in hypogalactia cases. It employs nor pharmacological methods of electric and massage stimulation models to activate the biomechanical, psychological, and neurological systems within the body. The electric stimulation model was performed for 10 minutes in acupoints SI, ST, and SP at 0.5 watts frequency. Meanwhile, the massage stimulation was performed for 30 minutes in acupoints GB, BL, ST, CV, and ST. Samples were divided into intervention and control groups, both characteristics and difference tests were performed. Paired t-test results show that there is a significant difference (p<0.05) in stress level with the treatment using both electric and massage stimulation models. Meanwhile, the unpaired t-test results also show differences in stress levels before and after treatment for each group, but the mean difference shows a decrease of 6.249. Therefore, it can be concluded that both electric and massage stimulation models lower stress levels for hypogalactia cases.

ABSTRACT Plasma levels of testosterone (T) and 5α-dihydrotestosterone (DHT) were determined by radioimmunoassay in 29 patients with benign prostatic hypertrophy (BPH) and in 56 control men of various ages. No significant difference was found in T, DHT nor DHT/T ratio between BPH and control subjects of similar age. Plasma DHT was higher in the prostatic than in the peripheral veins in 8/9 patients with BPH during laparotomy, indicating a prostatic secretion of DHT. No difference in the mean T nor the mean DHT was found in peripheral plasma before and after adenomectomy.

Background and Objective: Subclinical hypothyroidism can potentially develop to overt hypothyroidism. Thyroid hormones have substantial roles in metabolism and glucose homeostasis and thus are closely related to determinant factors of metabolic syndromes, such as obesity and insulin resistance. Osteocalcin is considered a predictor of metabolic conditions in thyroid diseases. This study aimed to investigate the effect of levothyroxine vs. placebo on serum osteocalcin levels in patients with subclinical hypothyroidism. Methods: This randomized clinical trial was performed on 30 patients with subclinical hypothyroidism who were referred to the endocrine clinics of Ghaem and Imam Reza hospitals in Mashhad, Iran. After giving informed consent, patients were randomly divided into intervention (50 µg/day levothyroxine for 2 months) and control (placebo) groups. Serum levels of osteocalcin, thyroid hormones, lipid profile, insulin, and fasting glucose, as well as other clinical and anthropometric data, were measured at baseline and at the end of the study. SPSS was used to analyze the data and P<0.05 was considered significant. Results: Mean age in the intervention and control groups was 35.07 ± 9.94 and 31.30 ± 4.30, respectively (P=0.20). There was no significant difference between osteocalcin levels before and after the intervention in either of the groups (P=0.54). TSH level was significantly decreased in the levothyroxine group after the intervention (P<0.01). T4 level was significantly increased in the intervention group (P=0.02). Conclusion: Levothyroxine had no significant effect on increasing the levels of serum osteocalcin in patients with subclinical hypothyroidism. We have registered the trial in the Iranian registry of clinical trials (IRCT) with the registration code IRCT20171129037677N1.

The Impact

More people working at offices are choosing to eat meals at their desks, making “desktop dining” an increasingly common phenomenon. Previous studies have reported that environmental distractors, such as television viewing, can influence meal intake and subsequent snack intake. However, the impact of stressful mental tasks on eating behavior has received relatively less attention, focusing only on subsequent meal intake or concurrent snack intake. This study sets out to determine whether eating while working influenced current meal energy intake. This research also examined the relationship between dietary restraint status and energy intake. A crossover experimental design was employed requiring participants (14 males and 29 females) to eat pizza quietly and at rest (control), and while working on a computer (work). Measurements included BMI, energy intake, state anxiety, restrained eating behavior, stress levels (pre- and post-eating), and appetite (before and after both work and control sessions). The findings showed that consuming food while working on a computer significantly increased stress but had no influence on energy intake compared to the control condition. However, post-eating hunger levels were significantly higher in the work condition compared to the control condition. As expected, satiety levels decreased significantly from pre- to post-eating for both work and control conditions. In addition, no significant relationship was observed between restrained eating behavior and energy intake in both work and control conditions. These results suggest that eating while working affected satiety of normal weight participants, as indicated by the significant difference in post-meal satiety levels between work and control conditions.

Introduction The aim of this study is to investigate the effect of cigarette smoke on turbinate reactivity and mucociliary clearance (MCC) in passive smokers. Methods 60 adult patients (30 passive smokers and 30 healthy subjects as the control group) were recruited for this study. Following a questionnaire on passive smoke exposure, MCC measurement using the saccharin test was carried out to all participants. The baseline and after decongestant acoustic rhinometry values (MCA1, MCA2, VOL1, VOL2) were measured and the percentage changes between the two test values (ie; response to nasal decongestants = concha reactivity) were recorded. Results All 60 patients, including 37 women (61.7%) and 23 men (38.3%) were between 18–57 years of age . MCC’s average measurements were 11.13 minutes in the passive smokers group, 7.87 minutes in the control group, which was statistically significantly different (p < 0.05). There was a statistically significant difference between the passive smokers and control group for acoustic rhinometric measurement of the ratio of MCA2 and VOL2 values before and after decongestant application (p < 0.05). Discussion Passive smoking can damage the nasal mucosa at least as active smoking. The number of studies on this subject is limited. There are no studies in the literature showing the effect of cigarette smoke on the inferior turbinate mucosal response. In our study, the inferior turbinate decongestant capacity was found to be significantly decreased in the passive smokers compared to the control group. Conclusion As a result of cigarette exposure, the erectile function of the lower turbines may be impaired. The task of the ENT physicians is to warn the passive smokers in this regard.

Background: The present study aimed to evaluate the effect of cold dialysis solution on the sexual dysfunction of patients with chronic renal failure undergoing hemodialysis. Methods: This randomized clinical trial was conducted with a before and after parallel design among 60 hemodialysis patients diagnosed with sexual dysfunction. The selected subjects were randomly allocated to the two groups of experimental and control (30 per each). Patients in the experimental and control groups underwent hemodialysis for one month using 35.5°C and 37°C dialysis solutions, respectively. Following the procedure, male and female sexual function was assessed in the study groups. Data were collected using the International Index of Erectile Functions, the female sexual function index (FSFI), and a demographic questionnaire. Data analysis was performed using Chi-square, Fisher's exact test, Mann-Whitney U test, t-test, paired t-test, and Wilcoxon test at 95% confidence interval. Results: No significant difference was observed between the experimental and control groups regarding male sexual function before and after the intervention (P > 0.05). However, the Mann-Whitney U test indicated a significant difference in the female subjects’ arousal in the experimental group before (3.68 ± 0.38) and after the intervention (3.98 ± 0.46; z = 2.216; P = 0.027). Conclusions: Cold dialysis solution could only increase the sexual arousal of the women in the experimental group, and no changes were observed in other sexual function domains of the male and female patients. Given the short duration of our intervention, it is recommended that further longitudinal studies be performed on larger cohorts of patients in different geographical regions.

Background: Bariatric surgery has resulted in body weight loss, which claimed by surgery removal specific parts of the stomach with enzyme or sleeve gastrectomy. Objectives: The aim of this study is to determine weight loss and endocrine changes by 12-week fundus resection and sleeve gastrectomy in rabbits. Methods: Twenty-one rabbits, weighing 2.5 - 3.5 kg, were divided into three groups (n = 7): sleeve gastrectomy, experimental fundus resection, and sham group. The weight of rabbits and total ghrelin and leptin levels in the plasma before and after surgery were measured in 12 weeks. Statistical analyses were performed using the Kruskal-Walis test for comparison of the means between the groups, and the difference after months in one group was assayed by Friedman test. Results: The results showed sleeve gastrectomy had a significant weight loss after one month when compared to fundus resection and sham-operated controls (P = 0.008). There was no significant difference in the ghrelin levels after these surgeries, but leptin levels decreased significantly after the fundectomy (P = 0.025). Conclusions: Sleeve gastrectomy is more efficient than the fundus resection in weight loss. It could be suggested as a new option in metabolic disorders due to the high level of leptin.
