Typology and characterization of goat milk production systems in the Cariris Paraibanos

This work was aimed to identify the typology and the characteristics of the goat milk production systems. Seventy rural properties were researched. Multivariate data analysis with cluster formation techinique was used, and also the identification of five different groups of production systems. The production systems were classified through technical and economical efficiency, ranking groups 1 and 2 as high technological level, groups 3 and 4 as medium level, and the group 5 as low level. The high technological level systems used practices of more rational handling with larger technological employment becoming better specialized. These systems present the largest revenues of milk and unitary net profit. Medium technological production systems adopt technological recommendations and look for alternatives of handling practices. Production system 1 adopts intensive sanitary practices for the farmyard facilities and stables, but this does not happen in the production system 2. Vermifuge is applied three times a year in system 1 while in the system 2 it is applied twice a year. The producers of the systems 1 and 2 obtain more financial resources through official credit lines, and the producers of the group 2 are more punctual on the pay off deadlines

Mensuração dos custos e avaliação de rendas em sistemas de produção de leite caprino nos Cariris Paraibanos

Objetivou-se mensurar o custo de produção do leite e avaliar a renda na atividade caprina por sistemas de produção. Os sistemas de produção estão localizados na microrregião dos Cariris Paraibanos e foram definidos por critérios de eficiência técnica e econômica, com método de agrupamento por análise multivariada e formação de cinco grupos. O método utilizado para o custo de produção foi o custo operacional, e o critério adotado para a conversão do custo da atividade leiteira para o custo do leite foi da participação da renda do leite na renda bruta da atividade. Os critérios adotados de análise de rendas foram margem bruta e margem líquida. No cômputo do custo de produção do leite de cabra, os valores foram de R$0,67/L; R$ 0,73/L; R$0,80/L; R$ 0,88/L; e R$1,21/L para os sistemas de produção 1, 2, 3, 4 e 5. Os sistemas de produção 1 e 2, de alta tecnologia, com margem líquida de R$ 9.147,30 e R$ 3.995,18 na atividade leiteira, foram os que apresentaram os menores custos e economicamente são os mais vantajosos

Strategies to increase HIV testing among men who have sex with men and transgender women: an integrative review

Abstract Background Men who have sex with men (MSM) and transgender women (TGW) are disproportionately affected by HIV, with much higher incidence and prevalence rates than in the general population in different countries. There are several barriers to testing among MSM and TGW, such as low risk perception, anticipation of HIV-related stigma, discrimination of sexual orientation, in addition to difficulties related to care and access to health services. Therefore, analyzing the available evidence of the effectiveness of strategies for scaling up HIV testing among key populations is essential to point out potential knowledge gaps which may need to be addressed and develop public health policies to promote testing and early diagnosis of HIV infection. Methods An integrative review was carried out to evaluate strategies for scaling up HIV testing in these populations. Search strategy was performed on eight electronic databases, without language restriction. We included clinical trials, quasi-experimental studies, and non-randomized studies. Study selection and data extraction were both performed independently by pairs and disagreements were solved by a third revisor. The screening of the studies was carried out through the selection of titles/abstracts and the reading of the full texts of the pre-selected studies based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Data extraction was performed using a structured form. Results Thirty-seven publications referring to 35 studies were included, mostly being carried out in the United States of America and Australia. No studies were found evaluating disaggregated data on TGW. The studies were grouped into four types of intervention strategies: self-test distribution system (n = 10), organization of health services (n = 9), peer education (n = 6), and social marketing campaign (n = 10). Strategies that focused on the first three groups, combined or not, were more effective in increasing HIV testing among MSM. Conclusions Considering the diversity of interventions and the methodological heterogeneity of the included studies, strategies especially involving self-test distribution systems, associated with new information and communication technologies, should be evaluated in different communities and social contexts. Research evaluating specific studies on TGW population is still needed

Foram pesquisadas 70 propriedades agrárias. A técnica utilizada foi análise multivariada com a formação de cluster, com identificação de cinco diferentes grupos de sistemas de produção. Os sistemas de produção foram tipificados pela eficiência técnica e econômica, como grupos 1 e 2, considerados de nível tecnológico alto, grupos 3 e 4, de nível médio, e grupo 5, de nível baixo. Os sistemas de nível tecnológico alto adotam práticas de manejo mais racionais com maior emprego tecnológico e são os mais especializados. Esses sistemas conferem as maiores receitas de leite e lucro líquido unitário. Os sistemas de produção de nível tecnológico médio adotam recomendações tecnológicas e buscam alternativas de práticas de manejo. Produtores do sistema de produção 1 utilizam práticas sanitárias intensivas das instalações de apriscos e currais para práticas mais alternadas realizadas no sistema de produção 2. O número de aplicações de vermífugo no sistema 1 é de três vezes ao ano, enquanto no sistema produtivo 2 é de duas aplicações. Os produtores dos sistemas 1 e 2 são os que mais captam recursos monetários por linha de crédito oficial, e os do grupo 2 os que mais se apresentaram com o financiamento quitado ou em dia

Global variation in postoperative mortality and complications after cancer surgery: a multicentre, prospective cohort study in 82 countries

© 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.
