Objective: To analyze and correlate the physical activity level (PAL) and the quality of life (QL) in patients with chronic kidney disease (CKD) undergone hemodialyses and to verify in practitioner of physical activity (PPA) if they follow rules and recommendations on their own practice. Methods: The QL (KDQOL-SFTM questionnaire), PAL (IPAQ questionnaire) and the evaluation of rules and recomendations to practice PA were analyzed in one hundred patients. Results: It was observed commitment on different dimensions of QL, higher values to sexual function and social support (88,6) and lower ones to professional paper (25,2) and physical function (47,7). Most patients shows low values of PAL and most PPA implement the exercises incorrectly. It was observed differences between PAL and some areas of QL. Conclusion: Patients with CKD undergone hemodialysis presented low values to PAL, commitment on QL, and most of the patients that realized PA did not implement rules and recomendations on their own practice.

Objective: To perform a global gonadal and sexual functions assessment in primary antiphospholipid syndrome (PAPS) patients. Methods: A cross-sectional study was conducted in 12 male PAPS patients and 20 healthy controls. They were assessed by demographic data, clinical features, systematic urological examination, sexual function, testicular ultrasound, seminal parameters according to the World Health Organization (WHO), seminal sperm antibodies, and hormone profile, including follicle stimulating hormone (FSH), luteinizing hormone (LH), morning total testosterone, and thyroid hormones. Results: The median of current age and age of spermarche were similar in PAPS patients and controls (37.5 vs. 32.4 years, p = 0.270, and 13.1 vs. 12.85 years, p = 0.224, respectively), with a higher frequency of erectile dysfunction in the former group (25% vs. 0%, p = 0.044). Further analysis of PAPS patients with and without previous arterial thrombosis demonstrated that the median penis circumference was significantly lower in PAPS with arterial thrombosis than in PAPS without this complication (8.1 [6-10] vs. 10.2 [10-11] cm, p = 0.007). In addition, the median penis circumference was significantly lower in PAPS patients with erectile dysfunction than in patients without this complication (7.5 [6-9.5] vs. 9.5 [7.5-11] cm, p = 0.039). Regarding seminal analysis, the median sperm concentration, sperm motility, and normal sperm forms by WHO guidelines were comparable in PAPS patients and controls (141.5 [33-575] vs. 120.06 [34.5-329] x 106/ml, p = 0.65; 61.29 [25-80] vs. 65.42 [43-82]%, p = 0.4; 21.12 [10-42.5] vs. 23.95 [10-45]%, p = 0.45, respectively), and none of them had oligo/azoospermia. No differences were observed between PAPS patients and controls regarding the frequency of antisperm antibodies, testicular volume by ultrasound, or hormone profile (FSH, LH, morning total testosterone, and thyroid hormone) (p > 0.05). Conclusions: Normal testicular function has been identified in PAPS patients, in spite of morphofunctional penile abnormalities. Previous arterial thrombosis may underlie penile anthropometry alteration. Lupus (2012) 21, 251-256.

Gynecologic cancer treatment can lead to anatomical changes in the genitalia that may impair sexual response. As a result, the authors aimed to assess women's self-perceptions of their sex lives following gynecologic cancer treatment and the impact of such treatment on sexual function. Thirty sexually active women were examined. At the first meeting with a physician sex therapist, women were asked about their satisfaction with their sexual activities prior to and after gynecologic cancer treatment, either with a partner or alone, and how many times per month they had sexual intercourse prior to the cancer diagnosis and after treatment. Women reported significantly worse sex lives and a significantly lower frequency of sexual relations following cancer treatment. All participants reported pain on vaginal penetration and feeling uncomfortable in discussing their sexual difficulties with the oncologist. The findings show that women experienced impaired sexual function, as well as poorer quality of sexual function, following gynecologic cancer treatment. Nurses should provide basic guidelines about sexual function to all patients who undergo treatment for gynecologic cancer.

Abstract Background Melatonin is associated with direct or indirect actions upon female reproductive function. However, its effects on sex hormones and steroid receptors during ovulation are not clearly defined. This study aimed to verify whether exposure to long-term melatonin is able to cause reproductive hormonal disturbances as well as their role on sex steroid receptors in the rat ovary, oviduct and uterus during ovulation. Methods Twenty-four adult Wistar rats, 60 days old (+/- 250 g) were randomly divided into two groups. Control group (Co): received 0.9% NaCl 0.3 mL + 95% ethanol 0.04 mL as vehicle; Melatonin-treated group (MEL): received vehicle + melatonin [100 μg/100 g BW/day] both intraperitoneally during 60 days. All animals were euthanized by decapitation during the morning estrus at 4 a.m. Results Melatonin significantly reduced the plasma levels of LH and 17 beta-estradiol, while urinary 6-sulfatoximelatonin (STM) was increased at the morning estrus. In addition, melatonin promoted differential regulation of the estrogen receptor (ER), progesterone receptor (PR), androgen receptor (AR) and melatonin receptor (MTR) along the reproductive tissues. In ovary, melatonin induced a down-regulation of ER-alpha and PRB levels. Conversely, it was observed that PRA and MT1R were up-regulated. In oviduct, AR and ER-alpha levels were down-regulated, in contrast to high expression of both PRA and PRB. Finally, the ER-beta and PRB levels were down-regulated in uterus tissue and only MT1R was up-regulated. Conclusions We suggest that melatonin partially suppress the hypothalamus-pituitary-ovarian axis, in addition, it induces differential regulation of sex steroid receptors in the ovary, oviduct and uterus during ovulation.

Come noto, il testosterone (T) gioca un ruolo importante in differenti funzioni fisiologiche. Il ruolo del T nelle donne è tuttavia largamente sconosciuto. Recenti studi riportano un ruolo del T nella modulazione della funzionalità sessuale femminile. SCOPO: Indagare gli effetti del T nelle donne, su parametri metabolici, ossei e composizione corporea e studiare gli effetti del T sulla proliferazione e innervazione della vagina. METODI: 16 soggetti FtM ovariectomizzati sono stati sottoposti a terapia con TU 1000 mg im + placebo o dutasteride. Alla settimana 0 e 54 sono stati valutati: parametri metabolici e composizione corporea. 16 campioni di tessuto vaginale ottenuti da soggetti FtM trattati con T, 16 donne PrM e 16 donne M sono stati analizzati. Sono stati valutati: morfologia, contenuto di glicogeno, espressione del Ki-67, recettori per estrogeni e androgeni ed innervazione. RISULTATI: La somministrazione di T in soggetti FtM determina aumento del colesterolo LDL e riduzione delle HDL. L’HOMA si riduce significativamente nel gruppo TU e tende ad aumentare nel gruppo TU+D. L’ematocrito aumenta. BMI, WHR e grasso tendono a ridursi, la massa magra ad aumentare. Non riportiamo cambiamenti del metabolismo osseo. Nel tessuto vaginale di FtM osserviamo perdita della normale architettura dell’epitelio. La somministrazione di T determina riduzione della proliferazione cellulare. I recettori per E e il PGP 9.5 sono significativamente ridotti nei FtM. La presenza di recettori per A è dimostrata nello stroma e nell’epitelio. L’espressione di AR si riduce con l’età e non cambia con la terapia con T nella mucosa, mentre aumenta nello stroma dopo somministrazione di T. CONCLUSIONI: Non riportiamo effetti avversi maggiori dopo somministrazione di T. La terapia con T determina ridotta proliferazione dell’epitelio vaginale. I recettori per AR sono presenti sia nello stroma che nell’epitelio. T aumenta l’espressione di AR nello stroma.

Background: Cardiovascular disease (CVD) is a common cause of morbidity and mortality in childhood chronic kidney disease (CKD). Left ventricular hypertrophy (LVH) is known to be one of the earliest events in CVD development. Left ventricular diastolic function (DF) is thought to be also impaired in children with CKD. Tissue Doppler imaging (TDI) provide an accurate measure of DF and is less load dependent than conventional ECHO. Aim: To evaluate the LV mass and the DF in a population of children with CKD. Methods: 37 patients, median age: 10.4 (3.3-19.8); underlying renal disease: hypo/dysplasia (N=28), nephronophthisis (N=4), Alport (N=2), ARPKD (N=3), were analyzed. Thirty-eight percent of the patients were on stage 1-2 of CKD, 38% on stage 3, 16% on stage 4. Three patients were on dialysis. The most frequent factors related to CVD in CKD have been studied. LVH has been defined as a left ventricular mass index (LVMI) more than 35.7 g/h2,7. Results: Twenty-five patients (81%) had a LVH. LVMI and diastolic function index (E’/A’) were significantly related to the glomerular filtration rate (p<0.003 and p<0.004). Moreover the LVMI was correlated with the phosphorus and the hemoglobin level (p<0.0001 and p<0.004). LVH was present since the first stages of CKD (58% of patients were on stages 1-2). Early-diastolic myocardial velocity was reduced in 73% of our patients. We didn’t find any correlation between LVH and systemic hypertension. Conclusion: ECHO evaluation with TDI is suggested also in children prior to dialysis and with a normal blood pressure. If LVH is diagnosed, a periodic follow-up is necessary with the treatment of the modifiable risk factors (hypertension, disturbances of calcium, phosphorus and PTH, anemia ).

Spinal cord injury (SCI) results not only in paralysis; but it is also associated with a range of autonomic dysregulation that can interfere with cardiovascular, bladder, bowel, temperature, and sexual function. The entity of the autonomic dysfunction is related to the level and severity of injury to descending autonomic (sympathetic) pathways. For many years there was limited awareness of these issues and the attention given to them by the scientific and medical community was scarce. Yet, even if a new system to document the impact of SCI on autonomic function has recently been proposed, the current standard of assessment of SCI (American Spinal Injury Association (ASIA) examination) evaluates motor and sensory pathways, but not severity of injury to autonomic pathways. Beside the severe impact on quality of life, autonomic dysfunction in persons with SCI is associated with increased risk of cardiovascular disease and mortality. Therefore, obtaining information regarding autonomic function in persons with SCI is pivotal and clinical examinations and laboratory evaluations to detect the presence of autonomic dysfunction and quantitate its severity are mandatory. Furthermore, previous studies demonstrated that there is an intimate relationship between the autonomic nervous system and sleep from anatomical, physiological, and neurochemical points of view. Although, even if previous epidemiological studies demonstrated that sleep problems are common in spinal cord injury (SCI), so far only limited polysomnographic (PSG) data are available. Finally, until now, circadian and state dependent autonomic regulation of blood pressure (BP), heart rate (HR) and body core temperature (BcT) were never assessed in SCI patients. Aim of the current study was to establish the association between the autonomic control of the cardiovascular function and thermoregulation, sleep parameters and increased cardiovascular risk in SCI patients.

During the last decade continent urinary diversion, especially orthotopic bladder substitution has become increasingly popular following radical cystectomy for bladder cancer. In general, if sphincter sparing surgery is possible, orthotopic bladder substitution is performed, if not then continent catheterisable reservoirs are a viable option. Strict patient selection criteria and improved surgical technique have had a positive influence on outcome, not only on survival but also on quality of life issues. It is becoming increasingly obvious, that a nerve sparing surgical technique not only improves sexual function but also continence. In addition, the length of the intestinal segment has an influence on continence and the degree of metabolic consequences, which are discussed in detail. Postoperative surveillance and instruction of patients is of utmost value for good functional results. Overall patient satisfaction and quality of life seem comparable in the various types of continent urinary diversions, and improved when compared to a urinary stoma. Continent urinary diversion offers a good quality of life with few long-term complications and should be considered the treatment of choice in the majority of patients, independent of sex.

Urinary diversion after cystectomy have evolved from simple diversion and protection of the upper tracts to functional and anatomic restoration as close as possible to the natural preoperative state. Over the past 15 years, orthotopic reconstruction has evolved from "experimental surgery" to the "preferred method of urinary diversion" in both sexes. Urologist that perform this technique should have an appropriate experience with pelvic surgery and be able to perform a nerve sparing radical cystectomy. Nevertheless, the postoperative management of these patients is more important than the surgical construction if good longterm results are to be achieved. For this reason, a great knowledge about the neobladder's physiology, postoperative complications and their treatment are needed. We review the most important aspects in the postoperative management of patients with ileal neobladder. We also resume the long term outcomes concerning to continence, sexual function, renal impairment, oncologic safety and quality of life.

BACKGROUND: Diabetic patients with transmetatarsal amputation (TMA) for chronic forefoot ulceration or necrosis are at high risk for postoperative skin breakdown and subsequent amputation. Locally applied antibiotics may reduce the revision rate and improve the outcome. MATERIAL AND METHODS: In a retrospective comparative study, 60 diabetic patients (65 feet) with forefoot ulceration or necrosis were treated with TMA by three surgeons in three hospitals. In the "beads group'' (46 patients, 49 feet) TMA was combined with local application of bioabsorbable, tobramycin impregnated calcium sulphate beads (OsteoSet-T beads, Wright Medical, Memphis, TN) as a single-stage procedure. The remaining 16 patients had transmetatarsal amputation without beads at the surgeon's discretion and acted as a control group. For all patients, time to healing, length of hospital stay, number of revisions for wound breakdown and conversions to a higher-level amputation were retrospectively reviewed. Of the 60 patients 17 had died and three were lost to followup, leaving 40 patients available for latest followup at 29 months. The Foot ; Ankle Outcome Score, Foot Function index, SF-36, and Comorbidity score were recorded. RESULTS: The revision rate for wound breakdown after TMA was 8.2% (4/49) in the beads group, and 25% (4/16) in the control group (p<0.05). At latest followup, 27% (13/49) in the beads group, and 25% (4/16) in the control group had to be converted to transtibial amputation. Patients in the beads group scored worse for activities of daily living in the FAOS and SF-36 (p < 0.05), and demonstrated more health problems in the Comorbidity scores (not significant), indicating sicker individuals in the beads group. CONCLUSION: Bioabsorbable calcium sulphate antibiotic beads may be a useful addition for TMA for patients with non-healing diabetic ulcerations of the forefoot. The single-stage procedure could have a significant impact on the management of diabetic forefoot ulcerations by preventing additional hospital stays, improving the patient's quality of life and minimizing cost.

Research on endocrine disruption in fish has been dominated by studies on estrogen-active compounds which act as mimics of the natural estrogen, 17β-estradiol (E2), and generally exert their biological actions by binding to and activation of estrogen receptors (ERs). Estrogens play central roles in reproductive physiology and regulate (female) sexual differentiation. In line with this, most adverse effects reported for fish exposed to environmental estrogens relate to sexual differentiation and reproduction. E2, however, utilizes a variety of signaling mechanisms, has multifaceted functions and targets, and therefore the toxicological and ecological effects of environmental estrogens in fish will extend beyond those associated with the reproduction. This review first describes the diversity of estrogen receptor signaling in fish, including both genomic and non-genomic mechanisms, and receptor crosstalk. It then considers the range of non-reproductive physiological processes in fish that are known to be responsive to estrogens, including sensory systems, the brain, the immune system, growth, specifically through the growth hormone/insulin-like growth factor system, and osmoregulation. The diversity in estrogen responses between fish species is then addressed, framed within evolutionary and ecological contexts, and we make assessments on their relevance for toxicological sensitivity as well as ecological vulnerability. The diversity of estrogen actions raises questions whether current risk assessment strategies, which focus on reproductive endpoints, and a few model fish species only, are protective of the wider potential health effects of estrogens. Available - although limited - evidence nevertheless suggests that quantitative environmental threshold concentrations for environmental protection derived from reproductive tests with model fish species are protective for non-reproductive effects as well. The diversity of actions of estrogens across divergent physiological systems, however, may lead to and underestimation of impacts on fish populations as their effects are generally considered on one functional process only and this may underrepresent the impact on the different physiological processes collectively.

Cancer is one of the leading causes of death in companion animals. Information on the epidemiology of cancer is instrumental for veterinary practitioners in patient management; however, spontaneously arising tumours in companion animals also resemble those in man and can provide useful data in combating cancer. Veterinary cancer registries for cats are few in number and have often remained short-lived. This paper presents a retrospective study of tumours in cats in Switzerland from 1965 to 2008. Tumour diagnoses were coded according to topographical and morphological keys of the International Classification of Oncology for Humans (ICD-O-3). Correlations between breed, sex and age were then examined using a multiple logistic regression model. A total of 18,375 tumours were diagnosed in 51,322 cats. Of these, 14,759 (80.3%) tumours were malignant. Several breeds had significantly lower odds ratios for developing a tumour compared with European shorthair cats. The odds of a cat developing a tumour increased with age, up to the age of 16 years, and female cats had higher risk of developing a tumour compared with male cats. Skin (4,970; 27.05%) was the most frequent location for tumours, followed by connective tissue (3,498; 19.04%), unknown location (2,532; 13.78%) and female sexual organs (1,564; 8.51%). The most common tumour types were epithelial tumours (7,913; 43.06%), mesenchymal tumours (5,142; 27.98%) and lymphoid tumours (3,911; 21.28%).
