High incidence of preventable deaths during childhood in Porto Velho, Rondonia - Brazil

Background: We aimed to estimate and analyze epidemiological profile of deaths during childhood. Method: We used the databases of deaths provided by Information System of mortality between 2006 and 2010. We selected only those records where the occurrence of deaths corresponded to Porto Velho city and those who were aged between 12 and 48 months old at the moment of death. We examined only deaths from preventable causes and poorly defined. Results: The total number of deaths was estimated to be 103, 48.6% male. High frequencies of deaths occurred (39.8%) in children before reaching two years old. Vast majority of deaths (66.9%) was due to preventable causes, 18.4% by poorly defined causes and nearly one in three by external causes. Approximately one in four were due to traffic accidents, 41.9% by drowning and submersion. Also, there were significant frequencies of deaths associated with respiratory diseases (17.5%) and infectious and parasitic diseases (16.6%). Conclusion: These findings reinforce the importance of studies of infant mortality, drawing attention to the debate on policy design to reduce childhood deaths, especially in acting on preventable causes.

Incidence of subclinical endometritis and its effects on reproductive performance of crossbred dairy cows

In dairy cattle, uterine infections are not life threatening and often unavoidable; however, they reduce fertility and increase the production costs of properties. The aim of this study was to evaluate the incidence of subclinical endometritis from 32 to 70 days in milk (DIM) and its effects on the reproductive performance of crossbred dairy cows. Lactating cows (Holstein/Gir; n = 172), with no history of retained placenta, without clinical signs of uterine infection were used. The body condition score (BCS) was evaluated on a scale from 1 to 5. Ultrasound examination was performed to evaluate uterine lining and ovarian activity, while vaginal mucus was analyzed by gloved hand. The diagnosis of subclinical endometritis was performed by endometrial cytobrush technique. The samples were collected, stained, and examined microscopically; positive cases for subclinical endometritis were considered with the presence of a parts per thousand yen5 % of neutrophils. Later, the cows were submitted to conventional artificial insemination or timed artificial insemination. The incidence of subclinical endometritis in the herd was 26 %, and this was not affected by the season of calving, presence of corpus luteum, DIM, and parity. Cows with a BCS a parts per thousand currency sign2.50 had a higher incidence of subclinical endometritis. The conception rate to first insemination and pregnancy rate at 150 days postpartum were not influenced by the presence of subclinical endometritis in crossbred dairy cows.

Clinicopathologic features and outcome of mycophenolate-induced colitis in renal transplant recipients

Reports on the clinical course of mycophenolic acid (MPA)-related colitis in kidney transplant recipients are scarce. This study aimed at assessing MPA-related colitis incidence, risk factors, and progression after kidney transplantation. All kidney transplant patients taking MPA who had colonic biopsies for persistent chronic diarrhea, between 2000 and 2012, at the Kidney Transplantation Unit of Botucatu Medical School Hospital, Brazil, were included. Cytomegalovirus (CMV) immunohistochemistry was performed in all biopsy specimens. Data on presenting symptoms, medications, immunosuppressive drugs, colonoscopic findings, and follow-up were obtained. Of 580 kidney transplant patients on MPA, 34 underwent colonoscopy. Colonoscopic findings were associated with MPA usage in 16 patients. The most frequent histologic patterns were non-specific colitis (31.3%), inflammatory bowel disease (IBD)-like colitis (25%), normal/near normal (18.8%), graft-versus-host disease-like (18.8%), and ischemia-like colitis (12.5%). All patients had persistent acute diarrhea and weight loss. Six of the 16 MPA-related diarrhea patients (37.5%) showed acute dehydration requiring hospitalization. Diarrhea resolved when MPA was switched to sirolimus (50%), discontinued (18.75%), switched to azathioprine (12.5%), or reduced by 50% (18.75%). No graft loss occurred. Four patients died during the study period. Late-onset MPA was more frequent, and no correlation with MPA dose or formulation was found.

Gestational protein malnutrition impairs c-myc and p63 protein expression, increases prostatic intraepithelial neoplasia incidence and prostatitis aggressiveness in adult male offspring subjected to hormonal handling

Background: Prostate cancer is the second most common cancer diagnosed in men; however its etiology remains unknown. Previous studies have shown that environmental adverse factors, such as maternal nutritional status during pregnancy, can influence fetal development and predispose people to diseases in adult life. The feeding of low-protein diets to pregnant rats result in fetal growth disturbance, androgen/estrogen unbalance and changes in the expression and sensibility of hormone receptors in male offspring. These alterations can promote permanent changes in androgen dependent organs, such as in the prostate. In this sense, we hypothesized that the hormonal unbalance that occurs during aging can lead to an increase in the susceptibility to prostatic disorders. Aim: To evaluate our hypothesis, malnourished male rat offspring were submitted to simultaneous estrogen and testosterone exposure in adulthood, to drive lesions in the rat ventral prostate gland (VP). Methods: 17 week-old Wistar rats (n=48) that received in utero normal protein diet (NP group, AIN93G=17% protein) or low protein diet (RP group, AIN93G modified=6% protein) were given implants with 17β-estradiol plus testosterone administration (NPH and RPH groups) for 17 weeks. The animals were killed at the age of 34 weeks and the VP were excised, weighted and processed for histopathological, immunohistochemical (Ki67, AR, p63, e-caderin, laminin, c-myc and GSTP), biochemical and ultrastructural analysis. Results: Both absolute and relative VP weight from NPH animals were about 30% higher than RPH. Serological data showed that estradiol levels were similar in both groups, but testosterone levels were lower in the RPH male offspring. The steroid hormone exposure in adult life promoted prostate lesions in both RPH and NPH offspring associated with reactive stroma. VP from RPH group exhibited heightened susceptibility to prostatic intraepithelial neoplasia (mainly cribriform and signet ring-cell patterns) and increased the incidence and aggressiveness of prostatitis. In this group, a higher proportion of basal cells, increased proliferation index, lower expression ofthe androgen receptor and increased focus of collagenous micronodules closely associated to epithelial neoplasias were also observed. Conclusion:These observations suggest that maternal protein restriction alters adult prostate response to androgen/estrogen handling and increases susceptibility to prostate diseases.
