Impact of Homeopathic Treatment on the Quality of Life of Women with Chronic Diseases: A Randomized Controlled Pragmatic Trial.

BACKGROUND: Despite the increasing demand for complementary and integrative medicine, only a few studies have evaluated the effect of these types of treatments on the quality of life (QoL) of patients with chronic diseases. The objective of this study was to evaluate the QoL of women treated with homeopathy within the Public Health System of Belo Horizonte, Brazil. METHODS: This is a prospective randomized controlled pragmatic trial. The patients were divided into two independent groups, one group underwent homeopathic treatment in the first 6-month period and the other did not receive any homeopathic treatment. In both randomized groups, patients maintained their conventional medical treatment when necessary. The World Health Organization Quality of Life abbreviated questionnaire (WHOQOL-BREF) was used for QoL analysis prior to treatment and 6 months later. RESULTS: Randomization afforded similar baseline results in three domains of QoL analysis for both groups. After 6 months' treatment, there was a statistically significant difference between groups in the physical domain of WHOQOL-BREF: the average score improved to 63.6 ± (SD) 15.8 in the homeopathy group, compared with 53.1 ± (SD) 16.7 in the control group. CONCLUSIONS: Homeopathic treatment showed a positive impact at 6 months on the QoL of women with chronic diseases. Further studies should be performed to determine the long-term effects of homeopathic treatment on QoL and its determinant factors.

Five-year follow-up of levonorgestrel-releasing intrauterine system versus thermal balloon ablation for the treatment of heavy menstrual bleeding: a randomized controlled trial.

BACKGROUND: The study was conducted to compare 5-year follow-up of levonorgestrel-releasing intrauterine system (LNG-IUS) or thermal balloon ablation (TBA) for the treatment of heavy menstrual bleeding (HMB). STUDY DESIGN: A prospective, randomized controlled trial comparing LNG-IUS (n=30) and TBA (n=28) was performed. Hysterectomy rates, hemoglobin level, bleeding pattern, well-being status and satisfaction rates were assessed. Comparisons between groups were performed by χ(2) test and by unpaired and paired t tests. RESULTS: After 5 years of follow-up, women treated with a TBA had higher rates of hysterectomy (24%) compared to the LNG-IUS group (3.7%) due to treatment failure (p=.039). Use of LNG-IUS resulted in higher mean hemoglobin (±SD) levels in comparison to the TBA group (14.1±0.3 vs 12.7±0.4 g/dL, p=.009). Menstrual blood loss was significantly higher in the TBA when compared to the LNG-IUS group (45.5% vs 0.0% p<.001). The psychological general well-being index scores were similar. Patient acceptability, perceived clinical improvement and overall satisfaction rates were significantly higher in women using LNG-IUS. CONCLUSION: Five-year follow-up of HMB treatment with LNG-IUS was associated with higher efficacy and satisfaction ratings compared to TBA.

Tissue specific localization of angiotensin-(1-7) and its receptor Mas in the uterus of ovariectomized rats.

The vasoactive peptide angiotensin (Ang)-(1-7) has vasodilator, antifibrotic and antihypertrophic properties, but little is known about its regulation in the uterus. The aim of this study was to evaluate Ang-(1-7) and its receptor Mas expression throughout rat uterine tissues, in ovariectomized animals treated with estrogen alone or combined with progestin. Adult Wistar rats (n = 19) were ovariectomized and randomly assigned into three different groups 1 week later. One group received a single dose of estradiol benzoate (1.5 mg/kg, i.m. injection, n = 6). Another group received estradiol associated with depot medroxyprogesterone acetate (3 mg/kg, i.m. injection, n = 6). Control group (n = 7) received oil injection. One week later, the rats were euthanized and their uteri were fixed and stained by immunohistochemistry, using a polyclonal antibody specific to Ang-(1-7) and its receptor Mas. Ang-(1-7) was detected in all uterine tissues, but it was weak or absent in the circular myometrium of treated animals. The intensity of the immunostaining decreased in the glandular epithelium of hormonally treated animals when compared to controls. In estrogen treated rats, Ang-(1-7) labeling was scattered and sometimes included the nuclei of glandular cells. We also detected Ang-(1-7) expression in longitudinal myometrium and uterine serosa. Mas receptor was present in all tissues with similar intensity among the tissue types in the control and estrogen plus progestin groups. In the estrogen group, Mas staining was stronger in the luminal and glandular epithelium when compared with stroma or circular myometrium. In conclusion, ovarian steroids are not required to allow endometrial expression of Ang-(1-7) and its receptor Mas in rats, as it remains abundant in ovariectomized animals. However, estrogen and progestin may modulate the distribution pattern of this peptide in the endometrium, especially in the glandular compartment.

Rapid thawing human sperm does not affect basic parameters in normozoospermic men: a double-blind prospective study.

PURPOSE: To compare sperm recovery from slow versus rapid thawing technique using thirty-eight normozoospermic human sperm samples, as follows. Twentyone samples from men taking part in routine infertility screening exams (infertile group) and seventeen from proven fertile volunteer men with at least one child (fertile group). MATERIALS AND METHODS: After analysis of motility, concentration, strict morphology and functional integrity of membranes, sperm was divided into two aliquots of 0.5 mL each and frozen in TyB-G medium. Samples were thawed at room temperature (25 ± 2° C) for 25 minutes (slow thaw) or in a water bath at 75° C for 20 seconds followed by water bath at 37° C for 3 minutes (rapid thaw). After thawing, motility, strict morphology and functional integrity of membranes were evaluated by a blinded investigator. The results were expressed as mean ± standard deviation for parametric variables and analyzed using Student's t-test. Data with unpaired non-parametric variables were expressed as median (interquartile range) and analyzed by the Mann-Whitney test. Wilcoxon test was used to analyze non-parametric paired variables. RESULTS: There was no significant difference between techniques for total and progressive motility, percentage of normal morphological forms, hypoosmotic swelling test. CONCLUSIONS: Although the rapid thawing protocol was completed in a shorter time (three minutes and 20 seconds versus 25 minutes, respectively), it wasn't harmful since both techniques showed comparable spermatozoa recovery. Additional research is needed to confirm its safety in clinical research before introducing this methodology in routine assisted reproduction.
