Introduction Cigarette smoking is highly prevalent among men. Many studies have evaluated the effect of cigarette smoking on levels of male reproductive hormones; however, the findings still remain controversial. Aim To evaluate the influence of cigarette smoking on serum levels of total testosterone (TT), free testosterone (FT), bioavailable testosterone (BT), sex hormone-binding globulin (SHBG), luteinizing hormone (LH), and follicle-stimulating hormone (FSH). Methods A total of 255 men (90 smokers and 165 nonsmokers), aged 30 to 70 years, were investigated. Weight and height were obtained and body mass index (BMI) was calculated. Also, waist circumference and hip circumference were measured and waist-to-hip ratio was obtained. Fasting blood samples were drawn for determination of plasmatic glucose levels and serum levels of total cholesterol, high-density lipoprotein cholesterol (HDL-c), triglycerides, albumin, prolactin, TT, SHBG, LH, and FSH. The values of low-density lipoprotein cholesterol (LDL-c) were determined by Friedwald equation and the values of FT and BT were calculated from TT, SHBG, and albumin. Statistical significance was set at P ≤ 0.05. Main Outcome Measures The influence of smoking on levels of TT, FT, and BT. Results No significant difference was observed in the mean values of TT (P = 0.580), FT (P = 0.869), BT (P = 0.933), SHBG (P = 0.279), LH (P = 0.573), and FSH (P = 0.693) in the different levels of pack-years when compared to nonsmokers. Moreover, after multivariate logistic regression, no association between increased pack-years of smoking and increased odds ratio for occurrence of low hormones and SHBG levels was observed. Conclusion In this study, smokers and nonsmokers had similar mean values of androgens, gonadotropins and SHBG. However, it is necessary to standardize pack-years of smoking in order to elucidate the influence of cigarette smoking on sex hormone levels, as well as to minimize differences among studies and to confirm our results.
Hydroxycitric acid (HCA), the main compound of Garcinia cambogia extract, is a competitive blocker of ATP-citrate-lyase, presenting a potential inhibition of fatty acid biosynthesis. Glucomannan fibers, abundant in Amorphophallus konjac, seem to reduce the absorption kinetics of dietary fat. Therefore, the aim of this double-blind randomized study was to evaluate the pharmacotherapeutic efficacy of standardized extracts of G. cambogia (52.4% HCA) plus A. konjac (94.9% glucomannan) in the treatment of obesity. Fifty-eight obese subjects (BMI 30.0-39.9 kg/m(2)) were assigned to the placebo group (n = 26) or the treatment group (n = 32); no dietary restrictions were applied. Over a 12-week period, subjects were given daily doses of either Garcinia (2.4 g) plus Konjac (1.5 g) or placebo prior to their main meals (3 times/day). Before the start of treatment, and every 4 weeks thereafter, the following were recorded: height, weight, circumferences and body composition, resting energy expenditure (REE), lipid profile and glucose levels. The treatment had no significant effect on anthropometric parameters, REE, triglycerides or glucose levels. However, a significant reduction was observed in total cholesterol (-32.0 +/- 35.1 mg/dL) and LDL-c levels (-28.7 +/- 32.7 mg/dL) in the treated group, the final levels being significantly lower than those of the placebo group (p = 0.008 and p = 0.020, respectively). The results obtained suggest that the treatment had a significant hypocholesterolemic effect, without influencing the anthropometric or calorimetric parameters tested.
Introduction Although Peyronie’s Disease (PD) was first described over 250 years ago, its precise etiology remains obscure. Aim Analyze a variety of potential associated factors with PD, including erectile dysfunction. Materials and Methods This cross-sectional study included 83 consecutive men with PD and 252 age-matched controls. All men completed the International Index of Erectile Function (IIEF) and were evaluated regarding their clinical and demographic characteristics, comorbidities, and used medications. Anthropometric measures included body mass index and waist circumference (WC). Fasting blood glucose, lipid profile, total testosterone, and dehydroepiandrosterone-sulfate were determined. Main Outcome Measures Clinical and laboratory characteristics associated to PD. Results The mean age was 59.2 ± 10 years in the cases and 59.7 ± 12 years in the controls. Marital status, current smoking, and excessive consumption of alcoholic beverages were similar between groups (P > 0.05). PD was more common among white skin color males (P = 0.001). The mean score for each IIEF domain and the androgen levels were similar in the two groups. Thiazides were the only medication associated to PD (P = 0.03). Dupuytren’s disease was more frequent among individuals with PD (P = 0.001). The distribution of all other comorbidities investigated was similar between groups (P > 0.05). The characteristics WC > 102 cm and levels of low-density lipoprotein (LDL) > 130 mg/dL were more prevalent in the controls (P <0.05). After multivariate analysis, white skin color (OR: 8.47, 95%CI: 1.98–36.24) and thiazide use (OR: 2.29, 95%CI: 1.07–4.90) were associated to PD, and LDL > 130 mg/dL (OR: 0.55, 95%CI: 0.32–0.92) and WC > 102 cm (OR: 0.53, 95%CI: 0.29–0.96) were inversely associated to PD. Conclusions In this study, PD was more common among white skin colored males. An inverse relationship with the presence of elevated serum levels of LDL and WC was observed. We found no association with medications other than thiazides and comorbidities other than Dupuytren’s disease. Androgen serum levels and sexual dysfunction had also no association to PD.
Lesions with great loss of skin and extensive burns are usually treated with heterologous skin grafts, which may lead rejection. Cell therapy with mesenchymal stem cells is arising as a new proposal to accelerate the healing process. We tested a new therapy consisting of sodium carboxymethylcellulose (CMC) as a biomaterial, in combination with adipose-derived stem cells (ADSCs), to treat skin lesions in an in vivo rat model. This biomaterial did not affect membrane viability and induced a small and transient genotoxicity, only at the highest concentration tested (40 mg/mL). In a rat wound model, CMC at 10 mg/mL associated with ADSCs increased the rate of cell proliferation of the granulation tissue and epithelium thickness when compared to untreated lesions (Sham), but did not increase collagen fibers nor alter the overall speed of wound closure. Taken together, the results show that the CMC is capable to allow the growth of ADSCs and is safe for this biological application up to the concentration of 20 mg/mL. These findings suggest that CMC is a promising biomaterial to be used in cell therapy.
Low TT levels were associated with MetS diagnosis. Abdominal obesity was the MetS component independently correlated to low TT levels.
