Association of maternal, fetal and labor variables with a low Apgar score in the fifth minute in term pregnancy: a case-control study.

PURPOSE: To search for maternal, labor-related and fetal variables associated with low Apgar in the fifth minute in term pregnancy. METHODS: A retrospective case-control study with term births was conducted in a public teaching hospital from 2013 to 2020. Cases were term births with Apgar score less than 7 in the fifth minute, and controls, the next one or two births following a case, with Apgar of 7 or more. Non-cephalic presentations, multiples and malformations were excluded. We accessed 100 cases and 190 controls. We considered significant values of p < 0.05. RESULTS: Were accessed 27 variables which could be risk factors, from which 12 were associated with the outcome. We found a protective effect of prelabor cesarean for the outcome, odds ratio (OR) 0.38, p = 0.013. Consequently, we conducted two sets of analyses: in the whole group and in the group of laboring women. The values of OR were in general greater in the group of laboring women, compared with the whole group. We conducted multivariate analysis within the group of women in labor. The variables which fitted best in the model were nulliparity, male sex of the fetus, less than six prenatal visits and abnormal cardiotocography; all remained significant. An association of rupture of membranes more than 360 min with the outcome, even after controlling fpr duration of labor, was found; adjusted OR 2.45, p = 0.023. CONCLUSION: Twelve variables were associated with the outcome. Prelabor cesarean had a protective effect. The time of ruptured membranes was associated with low Apgar.

Use of Alcohol Mixed with Energy Drinks Increases the Prevalence of Driving Violations among Brazilian Truck Drivers.

Background: The use of alcohol mixed with energy drinks (AmED) has been reported to be associated with a variety of unsafe driving practices. Truck drivers are vulnerable to driving violations, particularly because of their engagement in drug use. The use of AmED among these professionals remains unknown. Aim: To estimate the prevalence of AmED use and its association with driving violations among truck drivers. Methods: 684 drivers were recruited in Sao Paulo, Brazil. The use of drugs was reported. Drivers were split into three groups: (a) alcohol abstainers (AA); (b) alcohol-only users (AO); and (c) users of AmED. Intergroup comparisons were performed by polynomial logistic regression (the reference category was AO). We also performed Poisson regression analysis to obtain the prevalence ratio; the significance level was stipulated at 5%. Results: The prevalence of drivers reporting the use of AmED was 16.8%. Users of AmED (a) were younger, (b) were less experienced drivers, (c) had a heavier pattern of alcohol use, (d) used illicit drugs more frequently, and (e) had poorer sleep quality than AO subjects. A higher prevalence of drivers who had arguments or fights while driving (PR = 1.71) and of drivers who drove unbelted (PR = 1.66) ingested AmED than of AO subjects. Conclusions/importance: The use of AmED increased the prevalence of driving violations beyond the risks commonly attributed to alcohol use. We suggest additional investments in preventative measures based on the beverage category and a revision of the work organization of truck drivers to reduce their health and social risks.

Development of a User-Friendly Self-Screening Tool for Assessing Metabolic Syndrome Risk in Youths from Economically Challenged Regions.

BACKGROUND: Metabolic syndrome increases the risk of heart disease and diabetes. Early identification and management are crucial, especially in economically challenged regions with limited healthcare access. AIMS: To develop nomograms for individualized risk estimation for metabolic syndrome in young people from low-income regions. METHODS: We assessed 496 college students from two Brazilian cities with Gini indices ≤0.56. Of these, 69.9% were female, 65.1% were younger than 20 years, 71.8% were non-white, and 64.3% were enrolled in health-related courses. For external validity, we assessed metabolic syndrome in a subset of 375 students. RESULTS: We found 10 variables associated with abdominal obesity by logistic regression: age, biological sex, physical education facilities, enrollment in sports competitions during elementary school, grade retention, physical education as the preferred subject, physical education classes per week, and enrollment in sports training in secondary school (score A); adherence to 24 h movement behaviors (B score); and body weight (score C). We designed three nomograms (for scores A, B, and C), all of which showed acceptable performance according to the area under the receiver operating characteristic curve (≥0.70) and calibration (Hosmer-Lemeshow test, p > 0.05). In the external validation, we observed higher predictive capability for the A and B scores, while the C score had lower but still acceptable predictive ability. CONCLUSIONS: User-friendly self-reported data accurately predict metabolic syndrome among youths from economically challenging areas.

Even High-Quality CPGs Seldom Include Implementation Strategies.

Background: Implementation is a key step in ensuring that high-quality clinical practice guideline (CPG) recommendations are followed and have a positive impact. This step must be planned during CPG development. This study aims to inform professionals tasked with developing and implementing CPGs regarding implementation strategies and tools reported in high-quality CPGs for chronic non-communicable diseases (NCDs). Methods: NCD guidelines were selected based on Appraisal of Guideline Research and Evaluation (AGREE) II assessment. CPGs with a score of ≥60% in AGREE II domains 3 (rigor of development), 5 (applicability), and 6 (editorial independence), were considered high quality. The content related to implementation was extracted from CPG full texts and complementary materials. Implementation strategies and tools were assessed and classified using Mazza taxonomy. Results: Twenty high-quality CPGs were selected, most of which were developed by government institutions (16; 80%) with public funding (16; 80%); almost half (9; 45%) addressed the treatment of cardiovascular diseases. The countries with the most high-quality CPGs were the UK (6; 30%) and Colombia (5; 25%). These countries also had the highest average number of strategies, Colombia with 28 (SD = 1) distributed in all levels, and the UK with 15 (SD = 7), concentrating on professional and organizational levels. Although the content of the Colombian CPGs was similar regardless the disease, the CPGs from the UK were specific and contained data-based feedback reports and information on CPG compliance. Implementation strategies most frequently identified were at the professional level, such as distributing reference material (18; 80%) and educating groups of healthcare professionals (18; 80%). At the organizational level, the most frequent strategies involve changes in structure (15; 75%) and service delivery method (13; 65%). Conclusion: Countries with established CPG programs, such as the UK and Colombia, where identified as having the highest number of high-quality CPGs, although CPG implementation content had significant differences. Among high-quality CPGs, the most common implementation strategies were at the professional and organizational levels. There is still room for improvement regarding the implementation strategies report, even among high-quality CPGs, especially concerning monitoring of implementation outcomes and selection of strategies based on relevant implementation barriers.

Comparison of traffic data and blood alcohol concentration among fatally injured drivers in Norway and Sao Paulo, Brazil, 2005-2015.

Objective: Road traffic crashes (RTCs) are responsible for a large number of deaths worldwide, but low- and middle-income countries frequently present higher rates of deaths; for example, Norway, a high-income country, has a rate of 2.0 drivers killed per 100,000 inhabitants, whereas Brazil, a middle-income country, has a rate of 18.4. A significant fraction of RTCs are related to use of psychoactive substances, especially alcohol, due to its availability, legality, and relatively low price. The aim of the present study was to evaluate differences in alcohol-related fatal RTCs in Sao Paulo, the largest city in Brazil, and Norway during an 11-year period (2005-2015). Methods: The authors compared databases of drivers killed in RTCs in Sao Paulo and in Norway, a country renowned for its success in reducing traffic fatalities and keeping them at a low level. Results: In total, 772 victims from Norway (11 years, 2005 to 2015) and 584 victims from Sao Paulo (2 years, 2005 and 2015) were analyzed. Sao Paulo presented higher proportions of motorcycle drivers, men involved in RTCs, and blood alcohol concentration (BAC)-positive cases. The mean BAC for alcohol-positive cases was similar in both sites. For both regions, the percentage of alcohol-positive cases decreased during the study period (from 45.6% to 35.3% in Sao Paulo and from 24.4% to 15.8% in Norway) but remained higher for Sao Paulo. Conclusions: The study shows a different profile of RTC victims and higher alcohol consumption among drivers in Sao Paulo. The differences between the sites can possibly be attributed to public policies regarding traffic safety and alcohol control, which could be further improved by following the Norwegian model in Sao Paulo.

Alcohol use among fatally injured victims in São Paulo, Brazil: bridging the gap between research and health services in developing countries.

BACKGROUND AND AIMS: Most studies reporting alcohol use among fatally injured victims are subject to bias, particularly those related to sample selection and to absence of injury context data. We developed a research method to estimate the prevalence of alcohol consumption and test correlates of alcohol use prior to fatal injuries. DESIGN, SETTING AND PARTICIPANTS: Cross-sectional study based on a probability sample of fatally injured adult victims (n = 365) autopsied in São Paulo, Brazil. Victims were sampled within systematically selected 8-hour sampling blocks, generating a representative sample of fatal injuries occurring during all hours of the day for each day of the week between June 2014 and December 2015. MEASUREMENTS: The presence of alcohol and blood alcohol concentration (BAC) were the primary outcomes evaluated according to victims' socio-demographic, injury context data (type, day, time and injury place) and criminal history characteristics. FINDINGS: Alcohol was detected in 30.1% [95% confidence interval (CI) = 25.6-35.1)] of the victims, with a mean blood alcohol level (BAC) level of 0.11% w/v (95% CI = 0.09-0.13) among alcohol-positive cases. Black and mixed race victims presented a higher mean BAC than white victims (P = 0.03). Fewer than one in every six suicides tested positive for alcohol, while almost half of traffic-related casualties were alcohol-positive. Having suffered traffic-related injuries, particularly those involving vehicle crashes, and injuries occurring during weekends and at night were associated significantly with alcohol use before injury (P < 0.05). CONCLUSIONS: Nearly one-third of fatal injuries in São Paulo between June 2014 and December 2015 were alcohol-related, with traffic accidents showing a greater association with alcohol use than other injuries. The sampling methodology tested here, including the possibility of adding injury context data to improve population-based estimates of alcohol use before fatal injury, appears to be a reliable and lower-cost strategy for avoiding biases common in death investigations.

Alcohol and drug involvement in motorcycle driver injuries in the city of Sao Paulo, Brazil: Analysis of crash culpability and other associated factors.

BACKGROUND: Earlier studies have already identified that a greater proportion of injured drivers are under the effects of illicit drugs than alcohol in Brazil, but the crash risk attributable to each substance is still unknown. METHODS: Injured motorcycle drivers who were involved in traffic accidents in the West Zone of the city of Sao Paulo were recruited for a cross-sectional study based on crash culpability analysis. Alcohol and drug positivity among drivers was evaluated according to their responsibility for the crash. Culpability ratios were generated based on the proportion of drivers who were deemed culpable in relation to those considered not culpable according to the use of drugs and alcohol. RESULTS: Of the 273 drivers recruited, 10.6% tested positive for alcohol. Among those who were also tested for drugs (n=232), 20.3% had consumed either alcohol and/or other drugs, 15.5% of whom were positive only for drugs other than alcohol, specifically cannabis and cocaine. Drivers who tested positive for alcohol were significantly less likely to possess a valid driver's license and to report driving professionally, whereas those who had consumed only drugs were more likely to drive professionally. The culpability ratio estimated for alcohol-positive drivers was three times higher than that for alcohol-free drivers, showing a superior ratio than drivers who had consumed only drugs other than alcohol, who presented a 1.7 times higher culpability ratio than drug-free drivers. CONCLUSION: Substance use was overrepresented among culpable motorcycle drivers, with alcohol showing a greater contribution to crash culpability than other drugs.

Prevention of mother-to-child transmission of HIV in São Paulo State, Brazil: an update.

BACKGROUND: São Paulo State has had the largest number of paediatric AIDS cases in Brazil. Since 1996, São Paulo (and Brazil nationally) has implemented an aggressive programme to reduce perinatal transmission. We have gathered available indicators to examine the programme's impact. METHODS: We obtained data on reported AIDS cases from the AIDS surveillance system; data on the number of mother/infant pairs treated with zidovudine from the state logistics office responsible for distributing HIV medication; and the rates of perinatal transmission from a multicity study of the Brazilian Pediatric Society that includes a number of São Paulo facilities, which were compared with an independent study in 1995. The years for which data were available varied according to the source of the indicator. RESULTS: Annual reported cases of AIDS as a result of perinatal transmission fell 58.9% from 1997 to 2002. The number of cases treated with zidovudine increased 73.7% from 1997 to 2004. The rate of perinatal transmission among babies born to HIV-positive mothers fell from 16% in 1995 to 2.4% in 2002 in the reference clinics that participated in the Brazilian Pediatric Society study. CONCLUSION: Both process and outcome indicators point to the effectiveness of efforts to reduce perinatal transmission in São Paulo State.

Association between travel length and drug use among Brazilian truck drivers.

OBJECTIVE: To investigate whether the use of the stimulants amphetamines and cocaine by truck drivers in Brazil was related to travel length. METHODS: Truck drivers were randomly stopped by the Federal Highway Police on interstate roads in Sao Paulo State during morning hours from 2008 to 2011 and invited to participate in the project "Comandos de Saúde nas Rodovias" (Health Commands on the Roads). Participants were asked about the use of drugs, travel distance, and age, and gender was recorded. Samples of urine were collected and analyzed for amphetamine, benzoylecgonine (a metabolite of cocaine), and carboxytetrahydrocannabinol (THC-COOH; a metabolite of cannabis) by immunological screening and quantification by gas chromatography-mass spectroscopy. RESULTS: Current use of amphetamine, cocaine, and cannabis was reported by 5.7%, 0.7%, and 0.3% of the truck drivers, respectively. Amphetamine, benzoylecgonine, and THC-COOH were found in urine samples from 5.4%, 2.6,% and in 1.0% of the drivers, respectively. There was a significant association between the positive cases for amphetamine and reported travel length; 9.9% of urine samples from drivers who reported travel length of more than 270 km were positive for amphetamine, and 10.9% of those drivers reported current use of amphetamines. In most cases, appetite suppressants containing amphetamines had been used, but the purpose was most often to stay awake and alert while driving. Truck drivers with travel length of more than 270 km had significantly higher odds ratio (OR) for having a urine sample that was positive for amphetamine when adjusted for age as confounding factor (OR = 9.41, 95% confidence interval [CI], 3.97-22.26). No significant association was found between the use of cocaine or cannabis and travel length. CONCLUSION: Truck drivers who reported driving more than 270 km had significantly higher frequencies of urine samples positive for amphetamine and reported significantly more frequent current use of amphetamines than those who reported shorter driving distances.

Alcohol consumption in homicide victims in the city of São Paulo.

AIMS: To assess the association between alcohol use and victimization by homicide in individuals autopsied at the Institute of Legal Medicine in São Paulo, Brazil. DESIGN: Cross-sectional study. SETTING: Excessive consumption of alcohol is a serious public health issue and a major factor in triggering violent situations, which suggests a strong association between alcohol ingestion and becoming a victim of homicide. PARTICIPANTS: Data from 2042 victims of homicides in 2005 were obtained from medical examiner reports. MEASUREMENTS: The victim's gender, age, ethnicity and blood alcohol concentration (BAC) were collected. The method of death and homicide circumstances, as well as the date, time and place of death were also studied. FINDINGS: Alcohol was detected in blood samples of 43% of the victims, and mean BAC levels were 1.55 +/- 0.86 g/l. The prevalence of positive BAC levels was higher among men (44.1%) than women (26.6%), P < 0.01. Firearms caused most of the deaths (78.6%), and alcohol consumption was greater among victims of homicide by sharp weapons (P < 0.01). A greater proportion of victims with positive BAC were killed at weekends compared to weekdays (56.4 and 38.5%, respectively; P < 0.01), and the correlation between homicide rates and the average BAC for the central area of the city was positive (r(s) = 0.90; P < 0.01). CONCLUSIONS: These results highlight alcohol as a contributing factor for homicide victimization in the greatest urban center in South America, supporting public strategies and future research aiming to prevent homicides and violence related to alcohol consumption.
