Background. The most common complaints during climacteric are vasomotor symptoms. A circadian rhythm has been observed when hot flashes start; however, not much information is available in this field. Aims. To analyze whether the time (morning/evening) of administration of a compound containing 60 mg of dry soy seed extract (glycine max) with 40% of total isoflavones, primrose oil and α-tocopherol modifies the effect on the climacteric syndrome. Trial design. Multicentric, observational, open, prospective, longitudinal and cross-sectional study. Subjects and methods. One thousand six hundred eighty-two postmenopausal women with climacteric symptoms were allocated in two groups in order to receive the treatment in the morning (Group 1) or in the evening (Group 2), switching administration time after 3 months. Clinical evaluation was carried out at 0, 3 and 6 months of follow-up using BlattKupperman and Greene scales Results. 233 (13.9%) women dropped out from the study. Both administration times improved the climacteric symptoms after 3 and 6 months of treatment, showing a reduction in the scores of BlattKupperman and Greene scales (p < 0.001). No differences between both groups during the follow-up were identified. Conclusions. The time of administration of isoflavones does not modify its effect on climacteric symptoms. © 2011 Informa UK, Ltd.

Background There are many effects described, both experimental and clinical, that assess the relationship between isoflavones and bone. It has been hypothesized that isoflavones may have a positive effect on bone health. Objective To review the effects of isoflavones on biochemical markers of bone remodeling, bone density and bone quality, and finally on fracture incidence. Methods A systematic review was carried out of in vitro, animal, and human studies involving isoflavones and bone health. An electronic search was made, based on Internet search engines, MEDLINE (1966-June 2010) and the Cochrane Controlled Clinical Trials Register. This search was further supplemented by a hand-search of reference lists of selected review papers. Results After crossing-cleaning the reference lists, 737 studies dealing with isoflavones and bone were identified. Of these, 36 were considered selectable. From in vitro and animal studies, isoflavones appear to stimulate osteoblastic bone formation and inhibit osteoclastic bone resorption. Reviewed data show evidence of a beneficial effect of isoflavones on bone health in peri- and postmenopausal women when high-isoflavone soy protein is incorporated in the diet. Inconsistencies observed among data from different studies are related to differences in study design, the variety of soy sources of isoflavones, time of analysis, and the variability in the bioavailability and metabolism of isoflavones. Conclusions Most of the studies suggested a positive relationship between isoflavones and bone health. Further well-controlled, randomized, double-blind, clinical trials with a larger sample population, longer duration, and examination of various dosages are needed to better elucidate the inter-relationship between isoflavones and bone loss and to clarify whether isoflavones could prevent bone fractures. © 2011 International Menopause Society.

Introduction The persistence and compliance of patients in Spain with calcium and vitamin D supplementation are unknown, and thus the purpose of the present study was to determine the current figures. Methods This was a multicenter, cross-sectional study. Throughout Spain, 1342 primary-care physicians and specialists were asked to recruit 7888 patients aged 45 years or over, who had been prescribed with a calcium and vitamin D combination (CaVitD) at least 1 year prior to the study. Data on biodemographics, the reason for prescription and fracture risk factors were collected. Persistence with treatment, reasons for discontinuation, and compliance among persistent patients were assessed and patients' profiles analyzed. Results From the recruited sample, a total of 7624 patients were finally analyzed. Most subjects were postmenopausal (mean age 65.7±9.4 years). The main reason for CaVitD prescription was osteoporosis (56.3%), started 2-5 years earlier. A family history of osteoporosis (41.4) and previous fractures (40.7%) occurred frequently in the patients' clinical histories. At the study visit, 27.7% had discontinued CaVitD treatment, the main reason being fatigue due to the long-term treatment. Just 31.2% of persistent patients were adherent. Non-persistent patients were more likely to be smokers, alcohol consumers, have a long immobilization history, malabsorption syndrome and previous bone fractures. ConclusionsOnly two in ten patients effectively comply with CaVitD treatment after 1 year or more of its prescription. © 2010 International Menopause Society.

Context: Cervical cancer is the second most common tumor in women worldwide and due to diagnostic and therapeutic advances, the overall survival rates at 5 years is approaching 70%. Disorders in micturition, defecation, sexuality and quality of life have been described, frequently caused by different treatments. Addressing these comorbidities in the medical follow-up is often limited or nonexistent. Methods: A systematic review of studies to identify the articles related with urogynecological sequels from cervical cancer treatment was carried out. Summary of evidence: During radical hysterectomy, disruption of the autonomic nerve fibers which innervate the bladder appears to be the main cause of voiding dysfunction. Up to 36% of women report voiding dysfunction; from 10 to 80%, stress urinary incontinence (SUI), due to the decrease in urethral closure pressure. After radical hysterectomy and/or radiotherapy, vaginal shortening and stenosis after is often observed. Sexual function is altered in these women and those who are sexually active women after the surgery frequently report sexual dysfunction due to lack of lubrication and pain. Conclusions: Voiding dysfunction and urinary incontinence are the most frequent urinary problems that occur in patients treated for cervical cancer. Systemic urogynecologic assessment of the symptoms suggestive of micturition dysfunctions during oncologic follow-up may be useful to detect the cases that can be evaluated and treated in an Urogynecology Unit. © 2012 AEU.

Generating a catalogue of sperm nuclear proteins is an important first step towards the clarification of the function of the paternal chromatin transmitted to the oocyte upon fertilization. With this goal, sperm nuclei were obtained through CTAB treatment and isolated to over 99.9% purity without any tail fragments, acrosome or mitochondria as assessed by optical microscopy and transmission electron microscopy. The nuclear proteins were extracted and separated in 2-D and 1-D gels and the 2-D spots and 1-D bands were excised and analysed to identify the proteins through LC-MS/MS. With this approach, 403 different proteins have been identified from the isolated sperm nuclei. The most abundant family of proteins identified are the histones, for which several novel members had not been reported previously as present in the spermatogenic cell line or in the human mature spermatozoa. More than half (52.6%) of the proteins had not been detected in the previous human whole sperm cell proteome reports. Of relevance, several chromatin-related proteins, such as zinc fingers and transcription factors, so far not known to be associated with the sperm chromatin, have also been detected. This provides additional information about the nuclear proteins that are potentially relevant for epigenetic marking, proper fertilization and embryo development. © 2011 WILEY-VCH Verlag GmbH & Co.
