Despite evidence supporting the importance of breastfeeding to child health, breastfeeding practices remain suboptimal in Vietnam. There is currently little evidence on the importance of breastfeeding in the prevention of morbidity during infancy in Vietnam. In order to provide country specific data for policy makers to support breastfeeding friendly policies and programs, analysis was undertaken on a cross-sectional dataset to investigate the association between breastfeeding practices and prevalence of diarrhea and acute respiratory infection (ARI) among infants aged 0-5 months.', 'Data on socio-demographic characteristics, infant feeding practices and prevalence of diarrhea and ARI were obtained from 6,068 mother-child dyads in 11 provinces of Vietnam in 2011. Multivariate logistic regression was used to examine the associations between breastfeeding practices and child illnesses.', 'On average, the prevalence of diarrhea and ARI among infants 0-5 months was 5.3% and 24.5%, respectively. Though half of all infants were breastfed within one hour of birth, 73.3% were given prelacteal foods in the first three days after birth. Only 20.2% of children 0-5 months old were exclusively breastfed, while 32.4% were predominantly breastfed and 47.4% partially breastfed. After adjusting for confounders, early initiation of breastfeeding was associated with lower prevalence of diarrhea [adjusted odds ratio (AOR)\u2009=\u20090.74 (95% CI 0.58, 0.93)], while prelacteal feeding was associated with higher prevalence [AOR\u2009=\u20091.53 (95% CI 1.15, 2.03)]. Compared to infants who were exclusively breastfed, infants who were predominantly [AOR\u2009=\u20091.52 (95% CI 1.05, 2.21)] or partially breastfed [AOR\u2009=\u20091.55 (95% CI 1.07, 2.24)] were more likely to have diarrhea. Prelacteal feeding [AOR\u2009=\u20091.16 (95% CI 1.01, 1.33)] and partial breastfeeding [AOR relative to exclusive breastfeeding\u2009=\u20091.24 (95% CI 1.03, 1.48)] were associated with higher prevalence of ARI. While the protective effects of exclusive breastfeeding against diarrhea declined with child age, this effect for ARI appears to have remained constant.

The present analyses intend to clarify if gender and puberty modify the relationship between bone development (modeling and remodeling) and fat mass at the forearm.', 'Data were collected from participants (139 males, 157 females, age = 5-19 years) of the Dortmund Nutritional and Anthropometric Longitudinally Designed study in a cross-sectional investigation. The main outcome measures were total and trabecular bone mineral density (BMDtot and BMDtrab), strength strain index (SSI) and parameters associated with modeling (cortical area, CA; periosteal circumference, CP) and remodeling (cortical bone mineral density, BMDcort, endosteal circumference, CE) were analyzed in their relationship to cross-sectional fat (FA) and muscle area (MA) at the forearm.', 'BMDtot was correlated with FA in pubertal males (r = -0.25). BMDtrab was contrarily predicted by FA in pubertal males and females (r = -0.28 vs. 0.31). FA was correlated with BMDcort (r = -0.32) and CE (r = 0.26) in pubertal females. MA was positively correlated with CA, CP and SSI.

The 3q26 chromosome region, where the human telomerase RNA gene (hTERC) is located, is a biomarker for cervical cancer and precancerous lesions. The aim of this study was to confirm the value of measuring hTERC gene gain in predicting the progression of cervical intraepithelial neoplasia grade I or II (CIN-I and -II, respectively) to CIN-III and cervical cancer.', 'Liquid-based cytological samples from 54 patients with CIN-I or CIN-II lesions were enrolled in this study. Follow-up was performed with colposcopy and biopsy within 24 months after the diagnosis of CIN-I or CIN-II. Copy numbers of the hTERC gene were measured by fluorescence in situ hybridization with a dual-color probe mix containing the hTERC gene probe (labeled red) and the control, the chromosome 3 centromere-specific probe (labeled green).', 'All patients whose lesions progressed from CIN-I or CIN-II to CIN-III displayed a gain of the hTERC gene, whereas patients where the hTERC gene was not amplified did not subsequently progress to CIN-III or cervical cancer. The signal ratio pattern per cell was recorded as N:N (green:red). The numbers of cells with the signal ratio pattern of 4:4 or N:≥5 in patients whose lesions progressed to CIN-III were significantly higher than those whose lesions did not progress. Significantly, none of the patients with a 4:4 signal ratio pattern regressed spontaneously.
