Waist-to-height ratio and dynapenic abdominal obesity in users of hemodialysis services

BACKGROUND AND AIMS

Abdominal obesity and decreased muscle strength are risk factors for individuals on hemodialysis. Thus, the combination of these two factors known as dynapenic abdominal obesity acts as an important marker of the nutritional status of this population. Therefore, the objective of the work was to investigate the association between abdominal obesity, dynapenia, and sociodemographic, clinical, and nutritional factors in individuals with chronic kidney disease undergoing hemodialysis.

METHODS AND RESULTS

Cross-sectional study with 940 individuals undergoing hemodialysis in southeastern Brazil. Dynapenic abdominal obesity was defined by the combination of the presence of abdominal obesity, indicated by the waist-to-height ratio, and the reduction in muscle strength, measured by handgrip strength. Binary logistic regression was performed to calculate the odds ratio (OR) and the respective confidence intervals (95% CI). Dynapenic abdominal obesity was present in 45.42% of the study population. We found that being 18-59 years (OR: 3.17; 95% CI 2.35-4.28; p < 0.001) and being overweight (OR: 2.58; 95% CI 1.92-3.47; p < 0.001) increased the chances for the presence of dynapenic abdominal obesity; however, the habit of consuming meals away from home (OR: 0.63; 95% CI 0.47-0.85; p = 0.003) and having preserved behavioral adductor muscle thickness (OR: 0.52; 95% CI 0.38-0.71; p < 0.001) are considered protective factors.

CONCLUSION

Dynapenic abdominal obesity, present in individuals on hemodialysis, may represent a valid nutritional tool for assessing cardiovascular risk and mortality in this population, in order to implement the most effective preventive and/or therapeutic intervention possible.

A population-based study of the relationship between advanced maternal age and premature/early-term birth in Brazil

OBJECTIVE

To verify whether advanced maternal age (AMA), defined as women of ≥35 years, is associated with premature and early-term birth in Brazil, according to the onset of labor (spontaneous or provider-initiated).

METHODS

Cross-sectional population-based study. The "Birth in Brazil" study interviewed 23 894 puerperal women between 2011 and 2012, in all regions of Brazil. The current analysis included 17 994 adult mothers and their newborns (15 448 aged between 20-34 years, and 2536 ≥ 35 years). A propensity score was used to assess the likelihood of AMA women giving birth to premature or early-term infants (spontaneous or provider-initiated) compared to women aged 20-34 years. To balance the groups, we used maternal, prenatal, and childbirth characteristics.

RESULTS

The general prematurity rate was 10.24%, of which the majority of births were spontaneous (55.73%). Conversely, early-term births were more often provider-initiated (54.81%). AMA did not increase the chance of premature births, whether spontaneous or provider-initiated. However, AMA was associated with a higher rate of provider-initiated early-term birth (OR = 1.48; 95% CI: 1.23-1.77).

CONCLUSION

AMA alone does not contribute to premature birth; AMA's independent association with provider-initiated early-term birth may not be based solely on clinical indications.

[Adequacy of prenatal dental care: social and geographical inequalities in a metropolitan region of Brazil]

This study set out to analyze social and geographical inequalities in the adequacy of prenatal dental care in the Unified Health System (SUS) of the Greater Vitória Metropolitan Region, Espírito Santo, Brazil. A cross-sectional study was carried out with 1209 postpartum women living in the region admitted to hospital at SUS facilities for childbirth between 2010 and 2011. Data were collected on prenatal medical-dental care, the impact of oral health on the quality of life of pregnant women (Oral Health Impact Profile-14), and predisposing characteristics. Prenatal care was adequate when care corresponded to the recommended treatment. The adequacy of dental care during prenatal care was analyzed using a multivariate logistic model. Oral health was found to have an impact on the quality of life of 102 (8.4%) pregnant women and the adequacy of dental care during prenatal care was only 15.4% (n=156). There was a greater chance of adequacy of prenatal dental care in Vitória (OR=2.44; IC=1.63-3.66), in regions covered by the family health strategy (OR=1.88; IC=1.22-2.89), and in areas with a higher proportion of pregnant women with access to quality prenatal care (OR=3.59; IC=1.64-7.84). Contextual inequalities were decisive for the inadequacy of dental care in prenatal care.

Social and geographical inequalities in the performance of prenatal care in a metropolitan area of Brazil

This study analyzed the social and geographical inequalities in the performance of prenatal medical care in the Unified Health System (SUS) in the Metropolitan Region of Grande Vitória, Espírito Santo, Brazil. A cross-sectional study was carried out with 1,209 puerperae living in this region, admitted for childbirth from 2010 to 2011. Data about prenatal care and contextual, enabling, and social characteristics were collected, following the Andersen's Behavioral Model. The performance of prenatal care was classified into five levels, including information on the number of prenatal visits, initial and repetitive examinations, tetanus vaccination, gestational risk management, and participation in educational activities. The likelihood of different levels of prenatal care performance was analyzed using a multivariate multinomial model, according to maternal social variables. High prenatal coverage (98%) and 4.4% care adequacy were identified. The likelihood of access to prenatal care was increased by enabling, contextual, and social factors. The relationship between prenatal care quality and pregnant women's social and geographical conditions must be considered in the organization of services to achieve equity and reduce maternal and perinatal morbimortality.

[Diseases neglected by the media and strategies for visibility from the viewpoint of key actors]

Although health is a recurrent topic in newspapers, some diseases are visibly excluded from this coverage, originating diseases neglected by the media. The goal of this study was to identify - based on the opinion of journalists, press officers, health managers, and government health advisors - these diseases along with strategies for dealing with media neglect. The qualitative study was based on 19 semi-structured interviews with key actors. Data was submited to thematic content analysis using Maxqda software. The neglected diseases include infectious and parasitic diseases, rare diseases, periodontal diseases, cancer, and work-related illnesses.

Risk factors associated with adverse reactions to antituberculosis drugs

This review sought to identify the available scientific evidence on risk factors associated with adverse reactions to antituberculosis drugs. We performed a systematic review of studies published in the 1965-2012 period and indexed in the MEDLINE and LILACS databases. A total of 1,389 articles were initially selected. After reading their abstracts, we selected 85 studies. Of those 85 studies, 16 were included in the review. Risk factors for adverse reactions to antituberculosis drugs included age > 60 years, treatment regimens, alcoholism, anemia, and HIV co-infection, as well as sodium, iron, and albumin deficiency. Protective factors against hepatic adverse effects of antituberculosis drugs included being male (combined OR = 0.38; 95% CI: 0.20-0.72) and showing a rapid/intermediate N-acetyltransferase 2 acetylator phenotype (combined OR = 0.41; 95% CI: 0.18-0.90). There is evidence to support the need for management of adverse reactions to antituberculosis drugs at public health care facilities.
