Oropharyngeal colostrum immunotherapy and risk reduction of mortality in very low birth weight premature newborns: a clinical trial.

OBJECTIVE: To evaluate the effect of oropharyngeal colostrum immunotherapy (OCI) on the mortality of preterm newborns (PTNB) with very low birth weight (VLBW). METHOD: Non-randomized clinical trial, carried out with 138 mother-child pairs attended at a public maternity hospital. The treatment group used raw colostrum, dripping 4 drops (0.2 ml) into the oropharyngeal mucosa, totaling 8 administrations in 24 h, up to the 7th complete day of life (OCI). The control group was composed of newborns admitted to the same maternity hospital before the implementation of the OCI. Analyzes were performed: descriptive, bivariate, multiple logistic regression, and survival analysis, with a significance level of 5% and 95% CI. RESULTS: The treatment group had an RR of death of 0.26 (95% CI = 0.07-0.67; p = 0.00), adjusted for maternal age, marital status, gestational hypertension, type of delivery, number of prenatal visits, and birth weight. Number Needed to Treat (NNT) demonstrated that for every 5 individuals treated with OCI, one death was prevented NNT = 4.9 (95% CI = 1.84-5.20); however, for PTNB with VLBW who remained hospitalized for 50, 100 and 150 days, the NNT reduces to 4, 4 and 3, respectively. CONCLUSION: The OCI proved to be a beneficial intervention, since it reduced the risk of mortality in PTNB with VLBW when compared to the control group.

Indexes to assess feeding practices of children under 2 years old: a systematic review.

OBJECTIVE: To systematically review studies that used indexes to assess feeding practices of children under 2 years. DESIGN: Seven databases were searched with no limit on language or publication date. SETTING: The reviewed studies included thirteen Asian, ten Latin American, four European, four North American, three Oceanian and three African. PARTICIPANTS: Children under 2 years. RESULTS: We analysed thirty-six studies: twenty-two presenting original indexes and fourteen using adapted indexes. Among the original indexes, thirteen assess breast-feeding, fourteen food consumption, ten food groups, and ten other feeding practices. Original indexes were mainly adapted to fit the data available in the study, to update for current nutritional recommendations or to add components not present in the original indexes. Seven studies evaluated the associations between the indexes and nutrient intake or nutritional status. The main limitations cited by the authors were: flaws in the definition of the index components, criteria for cut-off points and weighting of the evaluated index components. CONCLUSIONS: The assessment of feeding practices for young children and its comparison across countries remains a challenge, especially due to the lack of consensus on the construction of indexes and regional differences in dietary recommendations and practices. Lack of validation for some indexes also makes it difficult to choose the most appropriate index for a given objective. Adapting existing indexes is a viable option. We point out relevant recommendations that may contribute to future research. Validation and longitudinal studies in diverse populations are favourable to qualify the assessment of feeding practices in this group.

Association between osteoporosis treatment and severe periodontitis in postmenopausal women.

OBJECTIVE: To estimate the association between osteoporosis treatment and severe periodontitis in postmenopausal women. METHODS: This cross-sectional study comprised of 492 postmenopausal women, 113 women in osteoporosis treatment, and 379 not treated. Osteoporosis treatment consisted of systemic estrogen alone, or estrogen plus progestin, and calcium and vitamin D supplements, for at least 6 months. Severe periodontitis was defined as at least two interproximal tooth sites with clinical attachment loss of at least 6 mm, and at least one interproximal site with probing depth of at least 5 mm; and dental caries experience was measured using the decayed, missing, and filled teeth (DMFT) index. Analysis included descriptive statistics and Poisson multivariate analysis with robust variance. RESULTS: Women receiving osteoporosis treatment had less periodontal probing depth, less clinical attachment loss, and less gingival bleeding than women not receiving treatment for osteoporosis (P ≤ 0.05). In the osteoporosis treatment group, the estimated mean DMFT index score was approximately 20, the most frequent component being the number of missing teeth, and in the nontreated group, the DMFT index was approximately 19. The prevalence of severe periodontitis was 44% lower in the osteoporosis treatment group than in the nontreatment group. The prevalence ratioadjusted was 0.56, 95% confidence interval was 0.31 to 0.99 (P = 0.05), after adjustments for smoking, age, family income, and visit to the dentist. CONCLUSIONS: The results suggest that women treated with estrogen for postmenopausal osteoporosis have a lower prevalence of severe periodontitis than women not receiving treatment.

Periodontal therapy and low birth weight: preliminary results from an alternative methodologic strategy.

BACKGROUND: The purpose of this study is to present the use of a non-randomized experimental design with multiple controls, with emphasis on a historical control group, as an alternative methodologic resource for studies on the association between periodontal disease and prematurity/low birth weight. METHODS: The sample consisted of 234 pregnant women: 54 in the Test Group (treatment of periodontal disease); 68 in Control Group I (without periodontal disease); and 112 in Control Group II (historical control group, with untreated periodontal disease). The diagnosis of periodontal disease was established by means of a complete clinical examination, using measurements of probing depth, gingival recession, clinical attachment loss, and bleeding index. The women in the Test Group were treated for periodontitis and followed-up with periodontal support therapy throughout their pregnancies. After delivery, they were reevaluated regarding their periodontal condition, and information on the newborn's birth weight was obtained. This was also done for Control Groups I and II. Descriptive analyses on the study variables were performed using the χ(2) and Fisher exact tests. Association measurements (relative risk) were obtained using a significance level of 5%. RESULTS: The frequency of low birth weight among the Test Group was similar to Control Group I and lower than Control Group II. CONCLUSION: The results suggest that successful periodontal therapy in pregnant women suffering from periodontitis is a protective factor promoting the birth of children with normal weight.
