Objective: The objective is to describe the results and the methodological processes of record linkage for matching deaths and malaria cases., Methods: A descriptive cross-sectional study was conducted with probabilistic record linkage of death and malaria cases data in Brazil from 2011 to 2020 using death records from the Mortality Information System (SIM) and epidemiological data from the Notifiable Diseases Information System (Sinan) and Epidemiological Surveillance Information Systems for malaria (Sivep-Malaria). Three matching keys were used: patient's name, date of birth, and mother's name, with an analysis of cosine and Levenshtein dissimilarity measures., Results: A total of 490 malaria deaths were recorded in Brazil between 2011 and 2020. The record linkage resulted in the pairing of 216 deaths (44.0%). Pairings where all three matching keys were identical accounted for 30.1% of the total matched deaths, 39.4% of the matched deaths had two identical variables, and 30.5% had only one of the three key variables identical. The distribution of the variables of the matched deaths (216) was similar to the distribution of all recorded deaths (490). Out of the 216 matched deaths, 80 (37.0%) had poorly specified causes of death in the SIM., Conclusions: The record linkage allowed for the detailing of the data with additional information from other epidemiological systems. Record linkage enables data linkage between information systems that lack interoperability and is an extremely useful tool for refining health situation analyses and improving malaria death surveillance in Brazil.

Background: The aim of this study is to analyze the production of 76 specialist hospitals for the morbidly obese in Brazil's public healthcare system (SUS) from 2010 to 2014 in terms of quantity and costs of bariatric surgery and its complications., Methods: Secondary data from the SUS Hospital Information System and the National Healthcare Establishments Registry were used. Current spending on bariatric surgery and its medical and postoperative complications were analyzed., Results: There was a 60 % rise in the number of surgeries between 2010 and 2014. This increase was not homogeneous among the hospitals studied, since only 19 performed the minimum number of surgeries required. Women accounted for 85 % of the surgeries carried out, and 32 % were aged between 35 and 44 years. The Roux-en-Y technique was the most widely used (93.7 % of the total), followed by sleeve gastrectomy. The ratio between the occurrence of medical complications and total number of surgeries performed in each hospital varied significantly (between 0 and 5.97 %) but was lower for postoperative complications, ranging from 0 to 1.7 %. There was a nominal increase of 44 % in average expenditure on postoperative complications between 2013 and 2014, while the average cost of medical complications decreased by 8.7 % in the same period., Conclusions: Despite the rise in the number of bariatric surgeries in Brazil, there is still a high demand for surgeries that is not being met, while most specialist hospitals fail to perform the minimum number of surgeries stipulated by the Ministry of Health.

1. This study was conducted to verify the impact of different kinds of material and the number of times of litter reuse on the incidence of chicken pathologies. Approximately 4·5 million broilers from conventional Brazilian farms were evaluated in the abattoir for cellulitis, arthritis and contact foot-pad dermatitis. 2. Four different kinds of litter material, Brachiaria grass, corncob, sawdust and rice shell, were used. Brachiaria grass litter showed the highest incidence of contact foot-pad dermatitis. Corncob litter also showed some negative effects on foot quality. Broilers raised on rice shell litter showed good results in terms of the incidence of contact foot-pad dermatitis. The best results were obtained with sawdust litter, because the incidence of cellulitis and arthritis were the lowest and the incidence of contact foot-pad dermatitis was also very low.

The reduction in time required to identify vancomycin-resistant enterococci (VRE) has gained increased importance during hospital outbreaks. In the present study, we implemented a laboratory protocol to speed up the VRE screening from rectal samples. The protocol combines a medium for selective VRE isolation (VREBAC(R), Probac, São Paulo) and a multiplex PCR for detection and identification of vanA and vanB resistance genes. The screening performance was analyzed in 114 specimens collected from four intensive care units. The swabs were collected at two periods: (1) during a VRE outbreak (February 2006, n=83 patients) and (2) at the post-outbreak period, after adoption of infection control measures (June 2006, n=31 patients). Forty-one/83 VRE (49.4%) and 3/31(9.7%) VRE were found at the first and second period, respectively. All isolates harbored the vanA gene. In both periods, detection of the gene vanA parallels to the minimum inhibitory concentration values of >256 microg/mL and >48 microg/mL for vancomycin and teicoplanin, respectively. Multiplex PCR and conventional methods agreed in 90.2% for enterococci identification. Besides this accuracy, we also found a remarkable reduction in time to obtain results. Detection of enterococcal species and identification of vancomycin resistance genes were ready in 29.5 hours, in comparison to 72 hours needed by the conventional methods. In conclusion, our protocol identified properly and rapidly enterococci species and vancomycin-resistance genes. The results strongly encourage its adoption by microbiology laboratories for VRE screening in rectal samples.
