Equity in health: tuberculosis in the Bolivian immigrant community of Sao Paulo, Brazil

Objectives To analyse the profile of tuberculosis (TB) among Bolivian immigrants, investigate the impact that this population has on the trends of TB and assess equity in access to TB treatment, in the city of Sao Paulo, Brazil. Methods Descriptive study of the epidemiological profile of TB in four city districts with large Bolivian populations, comparing cases among Brazilians and Bolivians, during the 19982008 period was carried out. We used logistic regression to adjust the treatment outcome for potential confounders. Results We identified 2056 new TB cases: 65.7% in Brazilians, 32.1% in Bolivians and 2.2% among other nationalities. Although TB incidence remained stable (high) over the study period, the annual proportion of cases among Bolivians increased from 15.0% to 53.0%. In comparison with the Brazilians, the Bolivians were younger (median age, 24 vs. 40 years; P < 0.0001) and presented a lower unemployment rate (3.1%vs. 11.6%; P < 0.0001), a lower rate of HIV co-infection (1.5%vs. 28.5%; P < 0.001), a higher proportion of individuals receiving supervised treatment (81.5%vs. 62.0%; P < 0.0001) and a higher proportion of cures (71.6%vs. 63.2%; P < 0.0001). After having been adjusted for potential confounder, cure after treatment was not associated with nationality. Conclusions Bolivian immigrants influenced the incidence but not the trends of TB among Brazilians in the study area. We found no significant differences between Bolivians and Brazilians regarding healthcare access or treatment outcome. Guaranteed universal health care access for all, including undocumented individuals, contributes to health equity. Specific intervention strategies are warranted for immigrants with tuberculosis.

Effects of a combined aerobic and strength training program in youth patients with acute lymphoblastic leukemia

Cure rates of youth with Acute Lymphoblastic Leukemia (ALL) have increased in the past decades, but survivor's quality of life and physical fitness has become a growing concern. Although previous reports showed that resistance training is feasible and effective, we hypothesized that a more intense exercise program would also be feasible, but more beneficial than low- to moderate-intensity training programs. We aimed to examine the effects of an exercise program combining high-intensity resistance exercises and moderate-intensity aerobic exercises in young patients undergoing treatment for ALL. A quasi-experimental study was conducted. The patients (n = 6; 5-16 years of age) underwent a 12-week intra-hospital training program involving high-intensity strength exercises and aerobic exercise at 70% of the peak oxygen consumption. At baseline and after 12 weeks, we assessed sub-maximal strength (10 repetition-maximum), quality of life and possible adverse effects. A significant improvement was observed in the sub maximal strength for bench press (71%), lat pull down (50%), leg press (73%) and leg extension (64%) as a result of the training (p < 0.01). The parents' evaluations of their children's quality of life revealed an improvement in fatigue and general quality of life, but the children's self-reported quality of life was not changed. No adverse effects occurred. A 12-week in-hospital training program including high-intensity resistance exercises promotes marked strength improvements in patients during the maintenance phase of the treatment for Acute Lymphoblastic Leukemia without side-effects. Parents' evaluations of their children revealed an improvement in the quality of life.

Metabolic syndrome, dyslipidemia, hypertension and type 2 diabetes in youth: from diagnosis to treatment

Overweight and obesity in youth is a worldwide public health problem. Overweight and obesity in childhood and adolescents have a substantial effect upon many systems, resulting in clinical conditions such as metabolic syndrome, early atherosclerosis, dyslipidemia, hypertension and type 2 diabetes (T2D). Obesity and the type of body fat distribution are still the core aspects of insulin resistance and seem to be the physiopathologic links common to metabolic syndrome, cardiovascular disease and T2D. The earlier the appearance of the clustering of risk factors and the higher the time of exposure, the greater will be the chance of developing coronary disease with a more severe endpoint. The age when the event may occur seems to be related to the presence and aggregation of risk factors throughout life.

Food choices and practices during pregnancy of immigrant and Aboriginal women in Canada: a study protocol

Abstract Background Facilitating the provision of appropriate health care for immigrant and Aboriginal populations in Canada is critical for maximizing health potential and well-being. Numerous reports describe heightened risks of poor maternal and birth outcomes for immigrant and Aboriginal women. Many of these outcomes may relate to food consumption/practices and thus may be obviated through provision of resources which suit the women's ethnocultural preferences. This project aims to understand ethnocultural food and health practices of Aboriginal and immigrant women, and how these intersect with respect to the legacy of Aboriginal colonialism and to the social contexts of cultural adaptation and adjustment of immigrants. The findings will inform the development of visual tools for health promotion by practitioners. Methods/Design This four-phase study employs a case study design allowing for multiple means of data collection and different units of analysis. Phase 1 consists of a scoping review of the literature. Phases 2 and 3 incorporate pictorial representations of food choices (photovoice in Phase 2) with semi-structured photo-elicited interviews (in Phase 3). The findings from Phases 1-3 and consultations with key stakeholders will generate key understandings for Phase 4, the production of culturally appropriate visual tools. For the scoping review, an emerging methodological framework will be utilized in addition to systematic review guidelines. A research librarian will assist with the search strategy and retrieval of literature. For Phases 2 and 3, recruitment of 20-24 women will be facilitated by team member affiliations at perinatal clinics in one of the city's most diverse neighbourhoods. The interviews will reveal culturally normative practices surrounding maternal food choices and consumption, including how women negotiate these practices within their own worldview and experiences. A structured and comprehensive integrated knowledge translation plan has been formulated. Discussion The findings of this study will provide practitioners with an understanding of the cultural differences that affect women's dietary choices during maternity. We expect that the developed resources will be of immediate use within the women's units and will enhance counseling efforts. Wide dissemination of outputs may have a greater long term impact in the primary and secondary prevention of these high risk conditions.
