First Detection and Characterization of Smacovirus in the Human Vagina in Two Sequential Samples over a Twelve-Day Interval.

BACKGROUND: Smacovirus is a CRESS-DNA virus identified almost exclusively in transient fecal samples from various vertebrate species. OBJECTIVE: We evaluated human vaginal samples for the presence and maintenance of Smacovirus. METHODS: Viral metagenomics analysis was performed on vaginal samples collected from 28 apparently healthy women in New York City, USA. Twenty-one of the women provided duplicate samples over a 12-21-day interval. RESULTS: Phylogenetic analysis identified two samples from the same individual, collected over a twelve-day interval, that were positive for the complete Smacovirus genome. All detected sequence contigs belonged to a single variant of CRESS-DNA. CONCLUSIONS: The continuous presence of Smacovirus in the human vagina over a twelve-day period was identified.

Use of alcohol before and after bariatric surgery.

OBJECTIVE: to assess alcohol intake in the bariatric surgery pre and postoperative periods. METHODS: Patients were interviewed at Surgery Clinic of the Hospital das Clínicas da Universidade Federal de Pernambuco - HC/UFPE (Brazil) from July 2011 to March 2012. We analyzed socioeconomic, anthropometric and clinical variables. We used the Alcohol Use Disorders Identification Test (AUDIT C). RESULTS: One hundred nineteen patients were enrolled (mean age: 41.23+11.30 years), with a predominance of the female gender (83.2%), non-Caucasian race (55%), married individuals or in a stable union (65.5%), with a high school education (40.3%)and active in the job market (37%). Weight and body mass index (BMI) were 128.77+25.28 Kg and 49.09+9.26 Kg/m2,respectively in the preoperative period (class II obesity) and 87.19+19.16 Kg and 33.04+6.21 Kg/m2, respectively in the postoperative period (class I obesity) (p<0.001). Hypertension was the most frequent disease in the pre (66.6%) and postoperative (36.5%) periods. The prevalence of alcohol use was 26.6% in the preoperative period, of which 2.2% of high risk, and 35.1% in the postoperative period, of which 1.4% of probable dependence; this difference did not achieve statistical significance (p=0.337). CONCLUSION: The prevalence of abusive alcohol intake and/or probable dependence was low in both the pre and postoperative periods, with little evidence of risky consumption among the patients submitted to bariatric surgery.

Alcohol intake in lactating women assisted in a University Hospital.

OBJECTIVE: To determine the prevalence of alcohol intake and the degree of alcohol-related risk among nursing mothers attended at the Child Care Service of Hospital das Clínicas of Universidade Federal de Pernambuco, Brazil. METHODS: A cross-sectional study was carried out with 157 nursing mothers enrolled in the Child Care Program of the university hospital. A questionnaire was administered addressing demographic and socioeconomic variables, type and duration of breastfeeding, smoking habits and consumption of foods considered as appetizers. The Alcohol Use Disorders Identification Test (AUDIT C) was applied for assessing alcohol consumption in the previous 12 months. Pearson's chi-square test and Fisher's exact test were used for statistical analysis. RESULTS: Twelve percent of the nursing mothers reported consuming alcoholic beverages, 100% of whom were classified as being at low risk for alcohol use disorders. The frequency of nursing mothers who consumed appetizers during alcohol consumption was 100%, the most common of which was cheese - 18 (95%). CONCLUSIONS: The prevalence of alcohol intake was low in the nursing mothers analyzed. The users exhibited a low risk for alcohol disorders and a high frequency of the consumption of appetizers during alcohol consumption.
