title: Prevalence of chronic low back pain: systematic review

description: OBJECTIVE To estimate worldwide prevalence of chronic low back pain according to age and sex. METHODS We consulted Medline (PubMed), LILACS and EMBASE electronic databases. The search strategy used the following descriptors and combinations: back pain, prevalence, musculoskeletal diseases, chronic musculoskeletal pain, rheumatic, low back pain, musculoskeletal disorders and chronic low back pain. We selected cross-sectional population-based or cohort studies that assessed chronic low back pain as an outcome. We also assessed the quality of the selected studies as well as the chronic low back pain prevalence according to age and sex. RESULTS The review included 28 studies. Based on our qualitative evaluation, around one third of the studies had low scores, mainly due to high non-response rates. Chronic low back pain prevalence was 4.2% in individuals aged between 24 and 39 years old and 19.6% in those aged between 20 and 59. Of nine studies with individuals aged 18 and above, six reported chronic low back pain between 3.9% and 10.2% and three, prevalence between 13.1% and 20.3%. In the Brazilian older population, chronic low back pain prevalence was 25.4%. CONCLUSIONS Chronic low back pain prevalence increases linearly from the third decade of life on, until the 60 years of age, being more prevalent in women. Methodological approaches aiming to reduce high heterogeneity in case definitions of chronic low back pain are essential to consistency and comparative analysis between studies. A standard chronic low back pain definition should include the precise description of the anatomical area, pain duration and limitation level.

title: Factors associated with exclusive breastfeeding in the first six months of life in Brazil: a systematic review

description: ABSTRACT OBJECTIVE To identify factors associated with exclusive breastfeeding in the first six months of life in Brazil. METHODS Systematic review of epidemiological studies conducted in Brazil with exclusive breastfeeding as outcome. Medline and LILACS databases were used. After the selection of articles, a hierarchical theoretical model was proposed according to the proximity of the variable to the outcome. RESULTS Of the 67 articles identified, we selected 20 cross-sectional studies and seven cohort studies, conducted between 1998 and 2010, comprising 77,866 children. We identified 36 factors associated with exclusive breastfeeding, being more often associated the distal factors: place of residence, maternal age and education, and the proximal factors: maternal labor, age of the child, use of a pacifier, and financing of primary health care. CONCLUSIONS The theoretical model developed may contribute to future research, and factors associated with exclusive breastfeeding may subsidize public policies on health and nutrition.

title: Techniques, Timing & Prognosis of Post Infarct Ventricular Septal Repair: a Re-look at Old Dogmas

description: Abstract Objective: The study aimed to identify the factors affecting the prognosis of post myocardial infarction (MI) ventricular septal rupture (VSR) and to develop a protocol for its management. Methods: This was a single center, retrospective-prospective study (2009-2014), involving 55 patients with post MI VSR. The strengths of association between risk factors and prognosis were assessed using multivariate logistic regression analysis. The UNM Post MI VSR management and prognosis scoring systems (UPMS & UPPS) were developed. Results: Thirty-day mortality was 52.5% (35% in the last 3 years). Twenty-eight (70%) patients underwent concomitant coronary artery bypass grafting. Residual ventricular septal defect was found in 3 (7.5%) patients. The multivariate analysis showed low mean blood pressure with intra-aortic balloon pump (OR 11.43, P=0.001), higher EuroSCORE II (OR 7.47, P=0.006), higher Killip class (OR 27.95, P=0.00), and shorter intervals between MI and VSR (OR 7.90, P=0.005) as well as VSR and Surgery (OR 5.76, P=0.016) to be strong predictors of mortality. Concomitant coronary artery bypass grafting (P=0.17) and location (P=0.25) of VSR did not affect the outcome. Mean follow-up was 635.8±472.5 days and 17 out of 19 discharged patients were in NYHA class I-II. Conclusion: The UNM Post-MI VSR Scoring Systems (UPMS & UPPS) help in management and prognosis, respectively. They divide patients into 3 groups: 1) Immediate Surgery - Patients with scores of &lt;25 require immediate surgery, preferably with extracorporeal membrane oxygenation support, and have poor prognosis; 2) Those with scores of 25-75 should be managed with "Optimal Delay" and they have intermediate outcomes; 3) Patients with scores of &gt;75 can undergo Elective Repair and they are likely to have good outcomes.

title: Intra-hospital organ and tissue donation coordination project: cost-effectiveness and social benefits

description: OBJECTIVE To evaluate the viability of a professional specialist in intra-hospital committees of organ and tissue donation for transplantation. METHODS Epidemiological, retrospective and cross-sectional study (2003-2011 and 2008-2012), which was performed using organ donation for transplants data in the state of Sao Paulo, Southeastern Brazil. Nine hospitals were evaluated (hospitals 1 to 9). Logistic regression was used to evaluate the differences in the number of brain death referrals and actual donors (dependent variables) after the professional specialist started work (independent variable) at the intra-hospital committee of organ and tissue donation for transplantation. To evaluate the hospital invoicing, the hourly wage of the doctor and registered nurse, according to the legislation of the Consolidation of Labor Laws, were calculated, as were the investment return and the time elapsed to do so. RESULTS Following the nursing specialist commencement on the committee, brain death referrals and the number of actual donors increased at hospital 2 (4.17 and 1.52, respectively). At hospital 7, the number of actual donors also increased from 0.005 to 1.54. In addition, after the nurse started working, hospital revenues increased by 190.0% (ranging 40.0% to 1.955%). The monthly cost for the nurse working 20 hours was US$397.97 while the doctor would cost US$3,526.67. The return on investment was 275% over the short term (0.36 years). CONCLUSIONS This paper showed that including a professional specialist in intra-hospital committees for organ and tissue donation for transplantation proved to be cost-effective. Further economic research in the area could contribute to the efficient public policy implementation of this organ and tissue harvesting model.

title: Spatial patterns of leprosy in a hyperendemic state in Northern Brazil, 2001-2012

description: ABSTRACT OBJECTIVE To describe the spatial patterns of leprosy in the Brazilian state of Tocantins. METHODS This study was based on morbidity data obtained from the Sistema de Informações de Agravos de Notificação (SINAN – Brazilian Notifiable Diseases Information System), of the Ministry of Health. All new leprosy cases in individuals residing in the state of Tocantins, between 2001 and 2012, were included. In addition to the description of general disease indicators, a descriptive spatial analysis, empirical Bayesian analysis and spatial dependence analysis were performed by means of global and local Moran’s indexes. RESULTS A total of 14,542 new cases were recorded during the period under study. Based on the annual case detection rate, 77.0% of the municipalities were classified as hyperendemic (&gt; 40 cases/100,000 inhabitants). Regarding the annual case detection rate in &lt; 15 years-olds, 65.4% of the municipalities were hyperendemic (10.0 to 19.9 cases/100,000 inhabitants); 26.6% had a detection rate of grade 2 disability cases between 5.0 and 9.9 cases/100,000 inhabitants. There was a geographical overlap of clusters of municipalities with high detection rates in hyperendemic areas. Clusters with high disease risk (global Moran’s index: 0.51; p &lt; 0.001), ongoing transmission (0.47; p &lt; 0.001) and late diagnosis (0.44; p &lt; 0.001) were identified mainly in the central-north and southwestern regions of Tocantins. CONCLUSIONS We identified high-risk clusters for transmission and late diagnosis of leprosy in the Brazilian state of Tocantins. Surveillance and control measures should be prioritized in these high-risk municipalities.

title: Recovery potencial of recyclables at a large residential condominium in São Caetano do Sul

description: ABSTRACT This paper aims at evaluating the potential recovery of recyclable materials at a large vertical residential condominium located in the municipality of São Caetano do Sul, state of São Paulo, Brazil. A survey on the waste management and the building facilities was conducted. Interviews with the governing board of the condominium and with the institute responsible for segregating recyclables were carried out, together with questionnaires applied to residents. The main challenge during this survey was the frequency and quality of internal communication for information and awareness, including both residents and respective domestic staff. As positive aspects, the convenience for disposal of recyclables by the residents; favorable conditions for the recyclables market, and presence of suitable location for storing segregated recyclables at the condominium were identified. It was found that the recovered materials were 13.7% of all recyclables present in domestic waste. This study showed that the selective collection of solid waste in residential condominiums is vulnerable owing to the lack of effective promoting and mobilization actions, as well lack of local administration decisions.

title: Pre-harvest cane burning and health: the association between school absences and burning sugarcane fields

description: The objective of this study was to investigate an association between pre-harvest sugarcane burning and respiratory diseases in children under five years of age. The following data were collected in five schools in the city of Araraquara, SP, Southeastern Brazil, between March and June 2009: daily records of absences and the reasons stated for these absences, total concentration of suspended particulate matter (µg/m3), and air humidity. The relationship between the percentage of school absences due to respiratory problems and the concentration of particulate matter in March and from April to June presented a distinct behavior: absences increased alongside the increase in particulate matter concentration. The use of school absences as indicators of this relationship is an innovative approach.

title: Use of causal chain for an institutional analysis of water resources management in a semiarid reservoir in Paraíba

description: ABSTRACT The Epitacio Pessoa Reservoir is the second largest water reserve in the State of Paraíba. It has been used for urban water supply, irrigation and fishing activities. In the last 15 years, this reservoir has faced two episodes of great depletion of its storage volume due to the occurrence of extreme drought events and problems in its management. An evaluation of Epitacio Pessoa Reservoir was performed under the institutional aspect of water resources management in three periods representing the high climatic variability in the region (dry and rainy periods) in which the reservoir is located. The definition of the proposed methodology of this study describes the diagnostic of water resources management and the use of the Causal Chain Analysis (ACC) methodology. The study considered technical, political-managerial and socio-economic-cultural causes. The research concludes that the lack of definition of strategies, which could be capable of minimizing eventual risks of reservoir be collapsed, occurred due to the weak performance of the entities on exercising their functions in a coordinated, articulated and integrated way. The results show there is a trend of the problem be worsened.
