Sera from 130 first trimester pregnant women were tested for their serum antibody level against a naturally occurring serum antigen purified from non-pregnancy sera. IgG and IgM antibody level was measured using enzyme linked immunosorbant assay. Results indicate that patients with multiple abortion (n=26) have significantly (p=0.0029) lower level of IgG antibody and significantly (p=0.0001) higher level of IgM antibodies; against the serum antigen as compared to the patients with successful pregnancies with no history of miscarriage (n=63). Western blot analysis identified the scrum antigen recognized by the IgM antibody as a 24 kDa molecular mass component. These IgG and IgM antibodies may play an important role in the outcome of pregnancy. 相似文献

Benign lesions of glottis creates stiffness of the vocal fold and inefficient glottal valve, aerodynamically effecting the
vocal quality by preventing smooth vocal edge closure. Introduction of phonomicrosurgical techniques based on Hirano ’s principle
of vocal fold epithelium have revolutionized results of voice surgery. Our experience in the management of benign vocal fold
lesions by phonomicrosurgical techniques with pre and post operative stroboscopic, perceptual and computerized acoustic voice
analysis is described. 相似文献

BackgroundChildren who inhabit the same house with tuberculosis (TB) patients are at high risk for infection and illness with TB. Nutritional status (stunting) in children is related to the child's ability to withstand MTB (Mycobacterium Tuberculosis). This study aims to estimated the prevalence of tuberculosis infection and its relationship to stunting in children (under five years) with household contact (HHC) with new TB cases.MethodsA cross-sectional design was implemented. Conducted in July 2018–April 2019 at 13 Public Health Center in Makassar City. The sample size was calculated using one sample situation-about precision formula. Samples were children under five who had contact with new diagnosed TB cases. Tuberculosis infection was measured by TST (tuberculin skin test). Logistic regression with causal model to examine TB infection relationship with stunting and covariate variable, analyzed using Stata/MP 13.0 software.ResultsOne hundred twenty-six (126) eligible children. Prevalence of tuberculosis infection was 38.10%. Frequency of stunted was 31 children (24.60%). Stunted nutritional status (aPR): 2.36, 95% CI 1.60–3.44), boys (aPR: 1.47, 95% CI 0.96–2.25), not getting BCG immunization (aPR: 1.58, 95%) CI 0.89–2.82), and high contact intensity (aPR: 2.62, 95% CI 1.10–6.22) best predicted the tuberculosis infection in children with TB case household contacts with a model contribution of 64%.ConclusionStunted nutritional status (moderate and severe), boys, not getting BCG immunization, and high contact intensity are the determinants of TB infection transmission in children HHC with TB. Children under five years of age who have close contact with TB cases should be targeted for priority interventions to prevent the transmission of TB infection and progressing to TB cases. 相似文献

Objective
The most prominent problem resulting from decreased body function in older adults is declining quality of life. Walking and talking among older adults in peer group may become a nursing therapy to improve their quality of life. The objective of this study was to identify the impact of walking and talking intervention of quality of life among community dwelling older adults in Depok, Indonesia.Method
This study applied quasi-experimental design with 43 and 40 older adults in the intervention and control group, respectively. The participants were selected using multistage random sampling method.Results
Based on t test, the average quality of life score of older adults improved more significantly in the intervention group than that in the control group, with p value of 0.003, its mean p value < α, respectively. An ANCOVA analysis was used to detect confounding factors. The result showed that all characteristics have a p value of > 0.05, which means there were no confounding factors warranting further investigation.Conclusions
It was concluded that walking and talking therapy in peer group significantly increase the quality of life of older adults. 相似文献9.

BACKGROUND/OBJECTIVES
The relationship between food intake and nutritional status has been clearly established. Yet, there are only limited studies on food intake among family members and their nutritional status. The study examined the relationship between intra-household food distribution and coexistence of dual forms of malnutrition (DFM) in the same household.SUBJECTS/METHODS
Households with a malnourished child and overweight mother were categorized as DFM. Intra-household food distribution among family members was reported using ratios, which are a measure of individual intakes as compared to all household member intakes adjusted to RDA.RESULTS
A 1,899 families were included in the study. The prevalence of DFM was 29.8% (95%CI 26.5-31.2). Children consumed lower amounts of energy (OR 1.34; 95%CI 1.06-1.69, P = 0.011), carbohydrates (OR 1.2; 95%CI1.03-1.61, P = 0.022), protein (OR 1.3; 95%CI 1.03-1.64, P = 0.026), and fat (OR 1.3; 95%CI 1.05-1.66, P = 0.016) than their mothers and other family members. In contrast, mothers consumed more carbohydrates than children and other family members (OR1.24; 95%CI 1.02-1.51, P = 0.03).CONCLUSIONS
This study is the first to report on the food distribution among family members and its relationship with occurrence of DFM in Indonesia. The results confirm the occurrence of an unequal food distribution between children and mothers, which increases risk of DFM in the household. The results also demonstrate that nutritional education at the household level is important to increase awareness of the impact of DFM. 相似文献10.
