Influence of torque and bone type on stability quotient of two implant platforms: a clinical trial.

The objective of this study was to analyze the influence of insertion torque, bone type, and peri-implant bone loss on implant stability quotient (ISQ) of cylindrical external hexagon (EH) and Morse Taper (MT) implants. Forty-four single implants were placed in the edentulous areas of 20 patients who met the inclusion and exclusion criteria. Immediately after implant placement (t1) and after osseointegration (four and six months for mandible and maxilla, respectively) (t2), insertion torque, resonance frequency, and peri-implant bone loss were measured using probing depths and digital periapical radiography. A significant difference was noted in the ISQ values between t1 and t2 in type III bone for EH and MT implants. No significant difference in bone loss values was observed when comparing bone types for EH or MT in all evaluated sites. Based on marginal bone loss assessed using radiography, there was no significant difference between the MT and EH groups. A positive correlation between torque and ISQ t1 value was observed for MT (correlation: 0.439; p = 0.041) and EH (correlation: 0.461; p = 0.031) implants. For EH and MT implants, the greater the insertion torque, the greater was the ISQ value (moderately positive correlation). A weak negative correlation was found between bone type and ISQ t1 for MT implants. Contrarily, no correlation was observed between bone type and ISQ t1 for EH implants. In all cases, bone loss around the implants was clinically normal.

Comparison of self-etching and conventional bifunctional coupling agent in lithium disilicate ceramic: A systematic review and meta-analysis.

Background: The aim of this systematic review is to determine the effectiveness of self-etching primers in comparison to the conventional protocol with hydrofluoric acid and silane treatment for bonding lithium disilicate ceramics. Material and Methods: The formulated PICO question for this research was: "Does self-etching silane primer surface treatment in lithium disilicate ceramics present a similar bond strength value compared to conventional hydrofluoric acid and silane treatment?". Combinations of words and appropriate truncations were adapted for each database. For the selection, duplicate articles were systematically eliminated using Mendeley software. The Cohen's Kappa statistic was then computed, RoBDEMAT questions were addressed, and the meta-analyses were conducted using RevMan 5.4, at a significance level of 5%. Results: Two independent reviewers conducted a blind and independent analysis of 190219 articles from PubMed, Scopus, Web of Science, and OpenGrey. Subsequently, they extracted data from 21 studies for the systematic review and in 16 the meta-analysis. In all in vitro studies, the most frequently cited concentration of hydrofluoric acid was 5%. In the meta-analysis, no statistical differences were observed between the two treatments concerning bond strength. Conclusions: Self-etching silane primers demonstrate promising results in lithium disilicate bonding, suggesting their potential as an alternative surface treatment to hydrofluoric acids + silane. Key words:Lithium disilicate, Hydrofluoric acid, Dental Porcelain, Ceramics, Silanes.

Aetiology and use of antibiotics in pregnancy-related infections: results of the WHO Global Maternal Sepsis Study (GLOSS), 1-week inception cohort.

BACKGROUND: Pregnancy-related infections are important contributors to maternal sepsis and mortality. We aimed to describe clinical, microbiological characteristics and use of antibiotics by source of infection and country income, among hospitalized women with suspected or confirmed pregnancy-related infections. METHODS: We used data from WHO Global Maternal Sepsis Study (GLOSS) on maternal infections in hospitalized women, in 52 low-middle- and high-income countries conducted between November 28th and December 4th, 2017, to describe the frequencies and medians of maternal demographic, obstetric, and clinical characteristics and outcomes, methods of infection diagnosis and causative pathogens, of single source pregnancy-related infection, other than breast, and initial use of therapeutic antibiotics. We included 1456 women. RESULTS: We found infections of the genital (n = 745/1456, 51.2%) and the urinary tracts (UTI) (n = 531/1456, 36.5%) to be the most frequent. UTI (n = 339/531, 63.8%) and post-caesarean skin and soft tissue infections (SSTI) (n = 99/180, 55.0%) were the sources with more culture samples taken and microbiological confirmations. Escherichia coli was the major uropathogen (n = 103/118, 87.3%) and Staphylococcus aureus (n = 21/44, 47.7%) was the commonest pathogen in SSTI. For 13.1% (n = 191) of women, antibiotics were not prescribed on the same day of infection suspicion. Cephalosporins (n = 283/531, 53.3%) were the commonest antibiotic class prescribed for UTI, while metronidazole (n = 303/925, 32.8%) was the most prescribed for all other sources. Ceftriaxone with metronidazole was the commonest combination for the genital tract (n = 98/745, 13.2%) and SSTI (n = 22/180, 12.2%). Metronidazole (n = 137/235, 58.3%) was the most prescribed antibiotic in low-income countries while cephalosporins and co-amoxiclav (n = 129/186, 69.4%) were more commonly prescribed in high-income countries. CONCLUSIONS: Differences in antibiotics used across countries could be due to availability, local guidelines, prescribing culture, cost, and access to microbiology laboratory, despite having found similar sources and pathogens as previous studies. Better dissemination of recommendations in line with antimicrobial stewardship programmes might improve antibiotic prescription.

Characterisation of an area of coexistent visceral and cutaneous leishmaniasis transmission in the State of Piauí, Brazil.

BACKGROUND: In Brazil, transmission of visceral and cutaneous leishmaniasis has expanded geographically over the last decades, with both clinical forms occurring simultaneously in the same area. OBJECTIVES: This study characterised the clinical, spatial, and temporal distribution, and performed entomological surveillance and natural infection analysis of a leishmaniasis-endemic area. METHODS: In order to characterise the risk of leishmaniasis transmission in Altos, Piauí, we described the clinical and socio-demographic variables and the spatial and temporal distribution of cases of American visceral leishmaniasis (AVL) and American cutaneous leishmaniasis (ACL) cases and identified potential phlebotomine vectors. FINDINGS: The urban area concentrated almost 54% of ACL and 86.8% of AVL cases. The temporal and spatial distribution of AVL and ACL cases in Altos show a reduction in the number of risk areas, but the presence of permanent disease transmission foci is observed especially in the urban area. 3,808 phlebotomine specimens were captured, with Lutzomyia longipalpis as the most frequent species (98.45%). Of the 35 females assessed for natural infection, one specimen of Lu. longipalpis tested positive for the presence of Leishmania infantum and Leishmania braziliensis DNA. MAIN CONCLUSION: Our results indicate the presence of risk areas for ACL and AVL in the municipality of Altos and highlight the importance of entomological surveillance to further understand a possible role of Lu. longipalpis in ACL transmission.

Unveiling the strong positive relationship: Maternal characteristics and neonatal outcomes in the Better Outcomes in Labour Difficulty (BOLD) study - a secondary analysis validating neonatal near miss classification.

Background: The near miss concept, denoting near collisions between aircraft, originated in aeronautics, but has recently been transferred to the neonatal context as a way of evaluating the quality of health services for newborns, especially in settings with reduced child mortality. However, there is yet no consensus regarding the underlying criteria. The most common indicators used to assess health care quality include mortality (maternal and neonatal) and life-threatening conditions. Using the World Health Organization (WHO) Better Outcomes in Labour Difficulty (BOLD) prospective cohort study data set, we conducted a secondary analysis to validate the near miss concept and explore the association between maternal and neonatal outcomes. Methods: We studied 10 203 singleton mothers treated between December 2014 and November 2015 in nine Nigerian and four Ugandan hospitals. We validated the near miss concept by testing the diagnostic accuracy (sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and odds ratio (OR)) using death as the reference variable and calculating the maternal and neonatal case fatality rates. We performed ordinal and binomial logistic regression, with the independent variables being those that had P < 0.1 in the univariate analyses. We considered the significance level of 5%. Results: We validated the neonatal near miss concept using the BOLD study data. We observed maternal and neonatal case fatality rates of 70.2% and 6.5%, with an increasing severity relationship between maternal and neonatal outcomes (P < 0.05). Ordinal logistic regression showed that gestational age <37 or >41 weeks and <8 antenatal consultations were related to a higher risk of neonatal severe outcomes, while maternal age between 30 and 34 years functioned as a protective factor against severe neonatal outcomes (SNO). Binomial logistic regression showed gestational age <37(OR = 1.46; 95% confidence interval (CI) = 1.07-1.94) or >41 weeks (OR = 2.26; 95% CI = 1.55-3.20), low educational level (OR = 1.76; 95% CI = 1.12-2.69), overweight/obesity (OR = 1.23; 95% CI = 1.02-1.47), one previous cesarean section (OR = 1.90; 95% CI = 1.36-2.61), one previous abortion (OR = 1.25; 95% CI = 1.00-1.56), and previous chronic condition (OR = 1.83; 95% CI = 1.37-2.41) were risk factors for SNO. Conclusions: The neonatal near miss concept could be used as a parameter for analysis in different health systems, to ensure that measuring of neonatal severity is comparable across health care units. In this analysis, we observed a progressive association between maternal severity and the severity of the newborns' outcomes.

Halitosis and Pain Threshold of Peri-Implant Tissues: An Observational Cohort Study.

In this study, we aimed to evaluate the halitosis and pain threshold of the peri-implant soft tissues in individuals rehabilitated with implant-supported prostheses. Forty-eight subjects were divided into four groups (n = 12) according to their prosthetic rehabilitation: single-tooth fixed prosthesis, multi-tooth fixed prosthesis, overdentures, and the Brånemark protocol. Halitosis was measured using a halimeter, whereas the pain threshold was measured using Von Frey monofilaments. Measurements were taken before (t0) and 30 days after (t1) placement of healing caps, and at the time of (t2) and 30 days after (t3) prosthetic placement. Halitosis data were analyzed using the chi-square test and Bonferroni correction (p < 0.05). Two-way ANOVA and Tukey's test (p < 0.05) were used to analyze pain threshold data. We noted an association between halitosis and time for the Brånemark protocol [X2(6) = 18.471; p = 0.005] and overdenture groups [X2(6) = 17.732; p = 0.007], and between halitosis and type of prosthesis only at t0 [X2(6) = 12.894; p = 0.045]. The interaction between time and the type of prosthesis significantly interfered with the mean pain threshold values (p = 0.001). At most time points, the majority of participants in each group had clinically unacceptable halitosis. After 30 days of using the prostheses, the overdenture group had a lower pain threshold compared to the Brånemark protocol group.

Lifestyle and Sense of Coherence: A comparative analysis among university students in different areas of knowledge.

BACKGROUND: The concept of health has undergone profound changes. Lifestyle Medicine consists of therapeutic approaches that focus on the prevention and treatment of diseases. It follows that the quality of life of university students directly affects their health and educational progress. EXPERIMENTAL METHODOLOGY: Socioeconomic, lifestyle (LS), and Salutogenesis Theory/sense of coherence (SOC) questionnaires were administered to college students from three different areas. The results were analyzed for normality and homogeneity, followed by ANOVA variance analysis and Dunn and Tukey post hoc test for multiple comparisons. Spearman's correlation coefficient evaluated the correlation between lifestyle and sense of coherence; p values < 0.05 were considered statistically significant. RESULTS: The correlation between LS and SOC was higher among males and higher among Medical and Human sciences students compared to Exact sciences. Medical students' scores were higher than Applied sciences and Human sciences students on the LS questionnaire. Exact science students' scores on the SOC questionnaire were higher than Human sciences students. In the LS areas related to alcohol intake, sleeping quality, and behavior, there were no differences between the areas. However, women scored better in the nutrition domain and alcohol intake. The SOC was also higher in men compared to women. CONCLUSION: The results obtained demonstrate in an unprecedented way in the literature that the correlation between the LS and SOC of college students varies according to gender and areas of knowledge, reflecting the importance of actions on improving students' quality of life and enabling better academic performance.

Resistência flexural de uma resina para impressão 3D comparada a resinas acrílicas convencionais empregadas para confecção de placas estabilizadoras de mordida / Flexural resistance of 3D printing resin compared to conventional acrylic resins employed to build occlusal bite splints

Introduction: with the technological advance in dentistry, light-polymerized three-dimensional (3D) printing resins had become an alternative for the manufacture of occlusal splint splints. Objective: the present study aimed to analyze the flexural strength of a resin for 3D printing compared to conventional acrylic resins (chemically activated and thermally activated), under the influence of thermocycling. Material and method: 60 specimens were made, which were distributed in six experimental groups (n = 10), according to the resin employed (chemically activated acrylic resin, thermally activated acrylic resin and 3D printing resin) and the treatment received (control and thermocycling). The specimens were submitted to flexural strength by the three-point flexural test. Result: data analysis showed that the material factor (<0.0001) and the thermocycling factor (p = 0.0096) influenced flexural strength, however, the interaction between the two factors did not (p = 0.9728). Conclusion: it was concluded that 3D printing resins presented the lowest flexural resistance to acrylic resins, especially when submitted to thermocycling.

Introdução: com o avanço tecnológico dentro da odontologia, as resinas fotopolimerizáveis para impressão tridimensional (3D) se tornaram uma alternativa para a fabricação de dispositivos interoclusais. Objetivo: o presente trabalho teve como objetivo analisar a resistência flexural de uma resina para impressão tridimensional comparada com resinas acrílicas convencionais (quimicamente ativada e termicamente ativada), sob a influência da termociclagem. Material e método: foram confeccionados 60 corpos de prova, que foram distribuídos aleatoriamente em seis grupos experimentais (n=10), de acordo com a resina utilizada (resina acrílica ativada quimicamente, resina acrílica ativada termicamente e resina para impressão 3D) e com o tratamento recebido (controle e termociclagem). Os corpos de prova foram submetidos ao ensaio de flexão de três pontos para determinação da resistência flexural. Resultado: a análise dos dados demonstrou que o fator material (<0.0001) e o fator termociclagem (p=0.0096) influenciaram a resistência flexural, entretanto, a interação entre os dois fatores não (p=0.9728). Conclusão: deste modo podemos concluir que a resina para impressão 3D apresentou desempenho inferior às resinas acrílicas, especialmente quando submetida a termociclagem.

Resumo Este estudo teve como objetivo avaliar a halitose e o limiar de dor dos tecidos moles peri-implantares em indivíduos reabilitados com próteses implantossuportadas. Um total de 48 indivíduos foram divididos em quatro grupos (n=12), de acordo com as reabilitações: prótese fixa unitária, prótese fixa multidentária, sobredentadura e protocolo de Brånemark. A halitose foi medida com um halímetro, enquanto o limiar de dor foi medido com monofilamentos de von Frey. As medições foram feitas antes (t0) e 30 dias após (t1) a colocação das tampas de cicatrização e no momento (t2) e 30 dias após (t3) a colocação da prótese. Os dados de halitose foram analisados por meio do teste qui-quadrado e correção de Bonferroni (p < 0,05). ANOVA de duas vias e o teste de Tukey (p < 0,05) foram usados para analisar os dados do limiar de dor. Observou-se associação entre halitose e tempo para o protocolo de Brånemark [X2(6) = 18,471; p = 0,005] e grupos overdenture [X2(6) = 17,732; p = 0,007], e entre halitose e tipo de prótese apenas em t0 [X2(6) = 12,894; p = 0,045]. A interação entre o tempo e o tipo de prótese interferiu significativamente nos valores médios do limiar de dor (p = 0,001). Na maioria dos pontos de tempos, a maioria dos participantes de cada grupo apresentava halitose clinicamente inaceitável. Após 30 dias de uso das próteses, o grupo overdenture apresentou menor limiar de dor em comparação ao grupo do protocolo de Brånemark.

A feather hydrogen (δ2H) isoscape for Brazil.

Spatial patterns of stable isotopes in animal tissues or "isoscapes" can be used to investigate animal origins in a range of ecological and forensic investigations. Here, we developed a feather hydrogen isotope (δ2Hf) isoscape for Brazil based on 192 samples of feathers from the family Thraupidae from scientific collections. Raw values of δ2Hf ranged from -107.3 to +5.0‰, with higher values at the Caatinga biome (northeast Brazil) and lower values at the Amazon and Pantanal. A Random Forest (RF) method was used to model the spatial surface, using a range of environmental data as auxiliary variables. The RF model indicated a negative relationship between δ2Hf and Mean Annual Precipitation, Precipitation in the Warmest Quarter, and Annual Temperature Range and positive relationships for amount-weighted February-April precipitation δ2H (δ2Hp(Feb-April)) and Mean Annual Solar Radiation. Modelled δ2Hf values ranged from -85.7 to -13.6‰. Ours is the first δ2Hf isoscape for Brazil that can greatly assist our understanding of both ecological and biogeochemical processes controlling spatial variation in δ2H for this region. This isoscape can be used with caution, due to its poor predictive power (as found in other tropical regions) and can benefit from new sample input, new GNIP data, ecological and physiological studies, and keratin standard material better encompassing the range in feather samples from Brazil. So, we encourage new attempts to build more precise feather H isoscapes, as well as isoscapes based on other elements.

Enzimas exógenas na dieta de leitões desmamados / Exogenous enzymes in the diet of weaned piglets

O desmame é caracterizado como o período mais crítico da produção de suínos devido à imaturidade digestiva e à baixa concentração de enzimas digestivas, como carboidrases, proteases e fitases, nas primeiras semanas do pós-desmame, o que ocasiona o baixo desempenho dos leitões. Neste caso, há a necessidade de suplementação exógena de enzimas que atuam na degradação de frações do alimento, aumentando o aproveitamento da dieta. A nutrição enzimática exógena tem sido considerada uma alternativa eficaz frente à baixa concentração de enzimas endógenas nas primeiras semanas após o desmame por contribuir para o aumento na digestibilidade das dietas sólidas e, deste modo, para um maior aproveitamento dos ingredientes. Na nutrição de suínos, as enzimas exógenas mais utilizadas são as carboidrases, as proteases e as fitases. Ademais, a utilização de blends enzimáticos também é considerada uma ótima alternativa, pois contribui para a inibição de fatores antinutricionais, os quais são responsáveis por indisponibilizar nutrientes necessários para o desenvolvimento e desempenho dos animais. Diante do exposto, o objetivo deste estudo foi apresentar as principais enzimas exógenas utilizadas na nutrição de leitões desmamados, bem como seus efeitos no desempenho animal.

Weaning is characterized as the most critical period in swine production due to digestive immaturity and low concentration of digestive enzymes, such as carbohydrases, proteases, and phytases, in the first weeks after weaning, which causes poor performance of piglets. In this case, there is the need for exogenous supplementation of enzymes that act on the degradation of food fractions, increasing diet utilization. Exogenous enzyme nutrition has been considered an effective alternative to the low concentration of endogenous enzymes in the first weeks after weaning, as it contributes to an increase in the digestibility of solid diets and, consequently, greater use of the ingredients. In swine nutrition, the most used exogenous enzymes are carbohydrases, proteases, and phytases. Furthermore, the use of enzymatic blends is also considered a great alternative, as they contribute to the inhibition of anti-nutritional factors, which are responsible for making nutrients necessary for the development and performance of animals unavailable. Therefore, this study aimed to present the main exogenous enzymes used in the nutrition of weaned piglets, as well as their effects on animal performance.

[Factors associated with serious maternal morbidity in Ribeirão Preto, São Paulo State, Brazil: a cross-sectional cohort study]. / Fatores associados à morbidade materna grave em Ribeirão Preto, São Paulo, Brasil: estudo de corte transversal.

This study investigated the factors associated with serious maternal morbidity (SMM) in women seen at public maternity hospitals in Ribeirão Preto, São Paulo State, Brazil. This was a cross-section analytical quantitative study. Participation included 1,098 postpartum women who had given birth at one of the four maternity hospitals in the municipality. Data were collected from August 3, 2015, to February 2, 2016, using face-to-face interviews and data obtained from patient records and prenatal cards. The dependent variable for data analysis was the serious maternal morbidity, that is, when the woman was classified as maternal near miss or potentially life-threatening condition based on WHO eligibility criteria. The study calculated the maternal near miss ratio, odds ratio (OR), 95% confidence interval (95%CI), and multiple logistic regression. The maternal near miss ratio was 3.6 cases per 1,000 live births. Complications occurred mainly during pregnancy (53.8%), and hypertensive disorders were the most frequent (49.4%). Multiple regression analysis showed an association between serious maternal morbidity and high-risk pregnancy (OR = 4.5, 95%CI: 2.7-7.7) and induced labor (OR = 2.1, 95%CI: 1.2-3.9). The occurrence of serious maternal morbidity mainly during pregnancy, featuring hypertensive syndromes, points to the need for better screening and management of high blood pressure in the prenatal period. The association between serious maternal morbidity and high-risk pregnancy also calls attention to prenatal care, for the demand for greater care for women classified as having gestational risk. Quality of care is a key point for dealing with maternal morbidity and mortality in Brazil.

Este estudo investigou os fatores associados à morbidade materna grave entre mulheres atendidas em maternidades públicas do Município de Ribeirão Preto, São Paulo, Brasil. Trata-se de um estudo quantitativo, analítico, transversal. Participaram 1.098 puérperas com parto em uma das quatro maternidades públicas do município. A coleta de dados ocorreu entre 3 de agosto de 2015 e 2 de fevereiro de 2016, a partir de entrevistas face a face, obtenção de informações dos prontuários e dos cartões da gestante. Para a análise de dados, considerou-se como variável dependente a ocorrência de morbidade materna grave, ou seja, quando a mulher era classificada como near miss materno ou condição potencialmente ameaçadora à vida a partir dos critérios de elegibilidade da Organização Mundial de Saúde. Calculou-se a razão do near miss materno, odds ratio (OR), intervalo de 95% de confiança (IC95%) e regressão logística múltipla. A razão do near miss materno foi de 3,6 casos por mil nascidos vivos. As complicações ocorreram principalmente na gravidez (53,8%) e os distúrbios hipertensivos foram os mais frequentes (49,4%). A análise de regressão múltipla mostrou associação entre morbidade materna grave e gestação de risco (OR = 4,5; IC95%: 2,7-7,7) e com trabalho de parto induzido (OR = 2,1; IC95%: 1,2-3,9). A ocorrência de morbidade materna grave, principalmente na gestação, com destaque para as síndromes hipertensivas, aponta para a necessidade de melhor rastreamento e manejo da elevação dos níveis pressóricos no pré-natal. A associação entre morbidade materna grave e gestação de risco também remonta ao pré-natal, para a demanda de uma maior atenção às mulheres classificadas como risco gestacional. A qualidade da assistência é ponto chave para o enfretamento da morbimortalidade materna no país.

La ocurrencia de morbilidad materna grave, principalmente en la gestación, resaltando los síndromes hipertensivos, apunta la necesidad de un mejor rastreo y gestión de la elevación de los niveles presión arterial en el período prenatal. La asociación entre morbilidad materna grave y gestación de riesgo también se remonta al período prenatal, con el fin de que se preste una mayor atención a las mujeres clasificadas como de riesgo gestacional. La calidad de la asistencia es un punto clave para combatir la morbimortalidad materna en el país.

Crossing birth and mortality data as a clue for prevalence of congenital diaphragmatic hernia in Sao Paulo State: A cross sectional study.

Background: Congenital diaphragmatic hernia (CDH) is a severe embryological defect that causes pulmonary hypoplasia and hypertension. The prevalence and mortality rate of CDH varies around the world and little information is available about CDH in Latin America. Our aim was to estimate the general prevalence, mortality rate, prevalence of associated anomalies and features related to the outcomes of CDH in newborns from São Paulo state, Brazil. Methods: Population-based cross-sectional study based on data gathered from the Live Births Information System (SINASC) and the Mortality Information System (SIM) of children born in São Paulo state between January 1st, 2006, and December 31st, 2017. Findings: From 7,311,074 total survival discharges between 2006 and 2017, 1,155 were CDH-related, resulting in a prevalence rate of 1:6329 (95%CI = 1/6715 - 1/5984) and a mortality rate of 63·72% (95%CI = 60.95 - 66.50), 510 presented complex associated anomalies (44·15%). Maternal data showed higher prevalence among older mothers (older than 35 years old: 2·13 per 10,000) and, also, women with more years of schooling (higher than 12 years: 1·99 per 10,000). Presence of associated anomalies (95%CI = 5.69-11.10), 1-min Apgar (95%CI = 1.44-2.95), maternal schooling (95%CI = 1.06-2.43) and birth weight (95%CI = 1.04-2.26) were the most significant features associated with mortality. Interpretation: There was 1 CDH case for every 6329 newborns in São Paulo and the mortality rate among those cases was 63·72% - a high rate compared to other countries. Funding: This study didn't receive any specific grant from any funding agency in the public, commercial or not-for-profit sectors.

Building an isoscape based on tooth enamel for human provenance estimation in Brazil.

In this study, we present a correlation between δ18OC values of carbonate in tooth enamel samples from the modern Brazilian population and the available δ18ODW data for the meteoric water from the Global Network of Isotopes in Precipitation (GNIP). Tooth enamel from 119 Brazilian individuals from five different regions of the country were analyzed. The δ18OC isoscape obtained is in good agreement with the isoscape based on regional meteoric and drinking water. The regression matrix obtained for the δ18O values of the carbonate tooth enamel and meteoric water was used to build an isoscape using the regression-kriging approach. Our data show that Brazil can be divided in two main regions with respect to the δ18O values of the carbonate tooth enamel: (1) the most easterly part of the northeast region, which is characterized by a warm and dry climate and (2) the remainder of the country, stretching from the Amazon rain forest to the more southernly regions. The data herein reported can be used for forensic purposes related to human identification.

The golden hour for postpartum hemorrhage: Results from a prospective cohort study.

OBJECTIVE: To evaluate the predictive capacity of vital signs for the diagnosis of postpartum hemorrhage (PPH). METHODS: A prospective cohort study performed at the University of Campinas, Brazil, between February 2015 and March 2016 with women who delivered vaginally. Vital signs and postpartum bleeding were collected over 24 h. Exploratory data analysis was performed plus receiver operating characteristic curve analysis where the areas under the curve was used to determine the best cutoff points for sensitivity, specificity, likelihood ratio, and diagnostic odds ratio. RESULTS: For the 270 women recruited, mean blood loss after 120 min was 427.49 ± 335.57 ml, while 84 (31.1%) and 22 (8.1%) women had blood loss ≥500 and ≥1000 ml, respectively. Heart rate cutoff point of 105 bpm measured between 21-40 min after birth identified blood loss ≥1000 ml with 90% specificity. A shock index (SI) of 0.965 at 41-60 min after birth identified blood loss ≥500 and ≥1000 ml within 2 h with approximately 95% specificity. CONCLUSION: Shock index and heart rate measured after birth showed high specificity with low sensitivity to identify PPH. In clinical practice, "The rule of 1s" should receive special attention: SI ≥1, or heart rate >100 bpm, or estimated blood loss ≥1 L.

Fatores associados à morbidade materna grave em Ribeirão Preto, São Paulo, Brasil: estudo de corte transversal / Factors associated with serious maternal morbidity in Ribeirão Preto, São Paulo State, Brazil: a cross-sectional cohort study / Factores asociados a la morbilidad materna grave en Ribeirão Preto, São Paulo, Brasil: estudio de corte transversal

Este estudo investigou os fatores associados à morbidade materna grave entre mulheres atendidas em maternidades públicas do Município de Ribeirão Preto, São Paulo, Brasil. Trata-se de um estudo quantitativo, analítico, transversal. Participaram 1.098 puérperas com parto em uma das quatro maternidades públicas do município. A coleta de dados ocorreu entre 3 de agosto de 2015 e 2 de fevereiro de 2016, a partir de entrevistas face a face, obtenção de informações dos prontuários e dos cartões da gestante. Para a análise de dados, considerou-se como variável dependente a ocorrência de morbidade materna grave, ou seja, quando a mulher era classificada como near miss materno ou condição potencialmente ameaçadora à vida a partir dos critérios de elegibilidade da Organização Mundial de Saúde. Calculou-se a razão do near miss materno, odds ratio (OR), intervalo de 95% de confiança (IC95%) e regressão logística múltipla. A razão do near miss materno foi de 3,6 casos por mil nascidos vivos. As complicações ocorreram principalmente na gravidez (53,8%) e os distúrbios hipertensivos foram os mais frequentes (49,4%). A análise de regressão múltipla mostrou associação entre morbidade materna grave e gestação de risco (OR = 4,5; IC95%: 2,7-7,7) e com trabalho de parto induzido (OR = 2,1; IC95%: 1,2-3,9). A ocorrência de morbidade materna grave, principalmente na gestação, com destaque para as síndromes hipertensivas, aponta para a necessidade de melhor rastreamento e manejo da elevação dos níveis pressóricos no pré-natal. A associação entre morbidade materna grave e gestação de risco também remonta ao pré-natal, para a demanda de uma maior atenção às mulheres classificadas como risco gestacional. A qualidade da assistência é ponto chave para o enfretamento da morbimortalidade materna no país.

This study investigated the factors associated with serious maternal morbidity (SMM) in women seen at public maternity hospitals in Ribeirão Preto, São Paulo State, Brazil. This was a cross-section analytical quantitative study. Participation included 1,098 postpartum women who had given birth at one of the four maternity hospitals in the municipality. Data were collected from August 3, 2015, to February 2, 2016, using face-to-face interviews and data obtained from patient records and prenatal cards. The dependent variable for data analysis was the serious maternal morbidity, that is, when the woman was classified as maternal near miss or potentially life-threatening condition based on WHO eligibility criteria. The study calculated the maternal near miss ratio, odds ratio (OR), 95% confidence interval (95%CI), and multiple logistic regression. The maternal near miss ratio was 3.6 cases per 1,000 live births. Complications occurred mainly during pregnancy (53.8%), and hypertensive disorders were the most frequent (49.4%). Multiple regression analysis showed an association between serious maternal morbidity and high-risk pregnancy (OR = 4.5, 95%CI: 2.7-7.7) and induced labor (OR = 2.1, 95%CI: 1.2-3.9). The occurrence of serious maternal morbidity mainly during pregnancy, featuring hypertensive syndromes, points to the need for better screening and management of high blood pressure in the prenatal period. The association between serious maternal morbidity and high-risk pregnancy also calls attention to prenatal care, for the demand for greater care for women classified as having gestational risk. Quality of care is a key point for dealing with maternal morbidity and mortality in Brazil.

La ocurrencia de morbilidad materna grave, principalmente en la gestación, resaltando los síndromes hipertensivos, apunta la necesidad de un mejor rastreo y gestión de la elevación de los niveles presión arterial en el período prenatal. La asociación entre morbilidad materna grave y gestación de riesgo también se remonta al período prenatal, con el fin de que se preste una mayor atención a las mujeres clasificadas como de riesgo gestacional. La calidad de la asistencia es un punto clave para combatir la morbimortalidad materna en el país.

Scientific sexism: the gender bias in the scientific production of the Universidade de São Paulo.

OBJECTIVE: To investigate gender inequity in the scientific production of the University of Sao Paulo. METHODS: Members of the University of Sao Paulo faculty are the study population. The Web of Science repository was the source of the publication metrics. We selected the measures: total publications and citations, average of citations per year and item, H-index, and history of citations between 1950 and 2019. We used the name of the faculty member as a proxy to the gender identity. We use descriptive statistics to characterize the metrics. We evaluated the scissors effect by selecting faculty members with a high H-index. The historical series of citations was projected until 2100. We carry out analyses for the general population and working time subgroups: less than 10 years, 10 to 20 years, and 20 years or more. RESULTS: Of the 8,325 faculty members, we included 3,067 (36.8%). Among those included, 1,893 (61.7%) were male and 1,174 (38.28%) female. The male gender presented higher values in the publication metrics (average of articles: M = 67.0 versus F = 49.7; average of citations/year: M = 53.9 versus F = 35.9), and H-index (M = 14.5 versus F = 12.4). Among the 100 individuals with the highest H-index (≥ 37), 83% are male. The male curve grows faster in the historical series of citations, opening a difference between the groups whose separation is confirmed by the projection. DISCUSSION: Scientific production at the Universidade de São Paulo is subject to a gender bias. Two-thirds of the faculty are male, and hiring over the past few decades perpetuates this pattern. The large majority of high impact faculty members are male. CONCLUSION: Our analysis suggests that the Universidade de São Paulo will not overcome gender inequality in scientific production without substantive affirmative action. Development does not happen by chance but through choices that are affirmative, decisive, and long-term oriented.
