RESUMO

BACKGROUND: The present study aims to assess the interrater reliability of the Global Leadership Initiative on Malnutrition (GLIM) criteria, a framework to provide a consensus diagnosis of malnutrition. We also aimed to investigate its concurrent and predictive validity in the context of patients with cancer admitted to the intensive care unit (ICU). METHODS: Individuals aged ≥19 years with cancer who were admitted to the ICU within 48 h of their initial hospital admission were included. Nutrition status was assessed with the Nutritional Risk Screening 2002, the Subjective Global Assessment (SGA), and the GLIM criteria. Interrater reliability was assessed by the kappa test (>0.80). The SGA served as the established benchmark for assessing concurrent validity. To evaluate predictive validity, the occurrence of mortality within 30 days was the outcome, and Cox regression models were applied. RESULTS: A total of 212 patients were included: 66.9% were at nutrition risk, and 45.8% were malnourished according to the SGA. According to the GLIM criteria, 68.4% and 66% were identified as malnourished by evaluators 1 and 2, respectively (κ = 0.947; P < 0.001). The GLIM combination incorporating weight loss and the presence of inflammation exhibited sensitivity (82.4%) and specificity (92%). In the multivariate Cox regression models, most GLIM combinations emerged as independent predictors of complications. CONCLUSION: The GLIM criteria demonstrated satisfactory interrater reliability, and the combination involving weight loss and the presence of inflammation exhibited noteworthy sensitivity and specificity. Most GLIM combinations emerged as independent predictors of 30-day mortality.

RESUMO

Ethylene is a plant hormone regulator that stimulates chlorophyll loss and promotes softening and aging, resulting in a deterioration and reduction in the post-harvest life of fruit. Commercial activated carbons have been used as ethylene scavengers during the storage and transportation of a great variety of agricultural commodities. In this work, the effect of the incorporation of copper oxide over activated carbons obtained from baru waste was assessed. Samples were characterized by X-ray diffraction (XRD), N2 adsorption-desorption at -196 °C, field-emission scanning electron microscopy (FESEM) coupled with energy-dispersive X-ray spectroscopy (EDS), and infrared (IR) spectroscopy. The results showed that the amount of ethylene removed using activated carbon obtained from baru waste and impregnated with copper oxide (1667 µg g-1) was significantly increased in comparison to the raw activated carbon (1111 µg g-1). In addition, carbon impregnated with copper oxide exhibited better adsorption performance at a low ethylene concentration. Activated carbons produced from baru waste are promising candidates to be used as adsorbents in the elimination of ethylene during the storage and transportation of agricultural commodities at a lower cost.

RESUMO

While cryopreservation of cauda epididymal sperm (SpCau) allows the preservation of post-mortem bulls' gametes, the process triggers sperm damage. Although improving post-thaw sperm quality, using egg yolk extenders (EY) raises biosafety concerns which forces the use of EY-free extenders (EYFE). Since EYFE are less efficient in preserving post-thaw sperm quality, a strategy for ejaculated sperm (SpEj) frozen with EYFE is to add an Equilibrium Time (ET) step period to the cryopreservation process. However, the ET effect on the quality of SpCau cryopreserved in EYFE remains unknown. Distinct from SpEJ, SpCau physiologically displays cytoplasmic droplets (CDs) in the flagellum that may benefit cell exchange during ET. We hypothesized that using ET in SpCau cryopreserved with EYFE impacts sperm morphofunctional features, CD area, and in vitro fertility ability. Extender nanoparticles were also assessed. Following collection from the cauda epididymis of six Nellore bulls by retrograde flow, SpCau were cryopreserved in EYFE BoviFree® (Minitube, Germany) using three ET protocols: ET0 (no-ET); ET2.5 (2.5 h-ET); and ET5 (5 h-ET). SpCau from ET2.5 and ET5 showed a higher (P ≤ 0.05) percentage of motility and integrity of plasma and acrosome membranes and a smaller (P ≤ 0.05) distal CD area. There are no differences in sperm abnormalities, oxidative stress, capacitation-like events, and in vitro fertility ability. However, a better sperm recovery was found after Percoll® selection for ET2.5 and ET5. Interestingly, the number of nanoparticles in the extender decreased in post-thawed samples. In conclusion, an ET of 2.5 or 5 h is required for an efficient SpCau cryopreservation using an EYFE.

RESUMO

OBJECTIVE: To overview the literature to answer the following question: "What is the performance of different therapies on wound healing and postoperative discomfort after palatal ASTG removal?" METHODS: SRs that evaluated the wound healing (WH), postoperative pain, bleeding, and analgesic consumption of patients submitted to de-epithelialized/free gingival grafts (FGG) or subepithelial connective tissue grafts (SCTG) removed from the palate were included. The searches were conducted on six white and two gray databases up to December 2023. Methodological quality was evaluated through AMSTAR 2. The synthesis of results was described as a narrative analysis. RESULTS: Ten SRs (involving 25 randomized clinical trials) related to low-level laser therapy (LLLT) (3), platelet-rich fibrin (PRF) (4), cyanoacrylate tissue adhesives (CTA) (2), and ozone therapy (OT) (1) were included in this overview. All techniques demonstrated improvements in WH. LLT, PRF, and CTA reduced pain and analgesic consumption. PRF and CTA reduced bleeding. Regarding methodological quality, the SRs were classified as critically low (2), low (5), moderate (2), or high quality (1). CONCLUSIONS: In SRs related to LLLT, PRF, CTA, and OT, the use of different therapies after palatal ASTG removal improved WH and postoperative discomfort. Due to the studies' low methodological quality and high heterogeneity, data should be interpreted with caution. CLINICAL RELEVANCE: The present overview compiles the evidence of SRs related to different therapies for WH and patients' postoperative experience and reveals that different treatments can significantly improve the clinical outcomes of patients who require ASTG removal for periodontal or peri-implant surgeries.

RESUMO

INTRODUCTION: Respiratory syncytial virus (RSV) is a causative virus for the common cold worldwide and can result in hospitalisations and even death in patients with high-risk conditions and older adults. However, the relationship between RSV or other incidental respiratory infections and acute exacerbations of underlying conditions has not been well investigated. The primary objective of this study is to estimate RSV prevalence, risk factors for adverse outcomes or hospitalisation and their effect on the hospital course of patients with acute respiratory symptoms admitted from emergency departments. Furthermore, we evaluate the prevalence of other respiratory viruses associated with respiratory symptoms. METHODS AND ANALYSIS: We are conducting a multicentre prospective cohort study in Japan. We plan to enrol 3000 consecutive patients admitted from emergency departments with acute respiratory symptoms or signs from 1 July 2023 to 30 June 2024. A nasopharyngeal swab is obtained within 24 hours of admission and the prevalence of RSV and other respiratory viruses is measured using the FilmArray Respiratory 2.1 panel. Paired serum samples are collected from patients with suspected lower respiratory infections to measure RSV antibodies at admission and 30 days later. Information on patients' hospital course is retrieved from the electronic medical records at discharge, death or 30 days after admission. Furthermore, information on readmission to the hospital and all-cause mortality is collected 180 days after admission. We assess the differences in clinical outcomes between patients with RSV or other respiratory viruses and those without, adjusting for baseline characteristics. Clinical outcomes include in-hospital mortality, length of hospital stay, disease progression, laboratory tests and management of respiratory symptoms or underlying conditions. ETHICS AND DISSEMINATION: The study protocol was approved by the institutional review boards of participating hospitals. Our study reports will be published in academic journals as well as international meetings. TRIAL REGISTRATION NUMBER: NCT05913700.

RESUMO

AIM: To assess the impact of late-onset neonatal sepsis (LONS) on the cognitive and motor development of five-year-old children who were born very preterm (VPT). METHODS: This study included 327 VPT children from the Portuguese EPICE/SHIPS cohort who attended the neurodevelopment assessment. Neuropsychological tests such as WPPSI-R, MABC-2 and NEPSY-II (language domain) were used to assess the children's cognitive and motor development. Statistical analysis was performed to compare the socio-demographic, clinical and neurodevelopment outcomes of VPT children with and without LONS. Regression analysis adjusted for confounding variables was performed when applicable. RESULTS: Underperformance in intelligence quotient and language development was similar regardless of a neonatal diagnosis of LONS. In contrast, VPT children with LONS had a higher risk of movement difficulties than those without LONS (p = 0.02). However, the association was lost after adjusting for confounders (ß = -0.25; p > 0.05). CONCLUSION: LONS per se was not associated with the risk for poor long-term cognitive or motor outcomes in VPT children. Social-demographic and clinical characteristics assessed during the neonatal period and at the time of neurodevelopment assessment were similar between groups suggesting that social-related factors such as parents' educational level could have mitigated the LONS impact.

RESUMO

INTRODUCTION: Retinoblastoma is a malignant tumor with a high cure potential when proper therapy is used. The purpose of this paper is to report the clinical features and outcomes of patients with retinoblastoma who were treated with a combination of local and systemic chemotherapy-based protocols. METHOD: We retrospectively studied patients treated with systemic chemotherapy plus local treatment between 2003 and 2015 with a follow-up ≥2 years. We correlated clinical and pathological characteristics with decimal visual acuity (VA) and death. RESULTS: Among 119 patients, 60% had unilateral disease (UNI), and 52% were male. The median presentation age was 19.5 months, 10% had a positive family history, and the most frequent sign was leukocoria (68.8%). Advanced disease was more frequent in eyes with UNI (98.4%) than in eyes with bilateral retinoblastoma (BIL: 55.3%). Enucleation was performed in 97% of UNI eyes and in 55.8% of BIL eyes. The overall globe salvage was 26.6%, 44.25% of BIL eyes. Bilateral enucleation was required in 5%. High-risk pathologic features occurred in 50% and 37% of eyes enucleated without and with neoadjuvant chemotherapy, respectively. High-risk features were related to the presence of goniosynechiae in the pathologic specimen and were more frequent in children younger than 10 months or older than 40 months. Extraocular disease was present in 5% of patients, and the death rate related to metastasis of the tumor was 8%. The final VA was ≥ 0.7 in 72.8% and ≥0.1 in 91% of BIL patients. CONCLUSIONS: Treatment of retinoblastoma with conservative systemic-based chemotherapy was associated with an excellent survival rate (92%). Albeit the low overall globe salvage rate, in BIL patients, approximately half the eyes were conserved, and a satisfactory functional visual result was achieved The evaluated protocol is an important treatment option, especially in developing countries.

RESUMO

OBJECTIVE: To evaluate the temporal trend of bronchopulmonary dysplasia (BPD) in preterm infants who survived to at least 36 weeks' post-menstrual age (PMA) and BPD or death at 36 weeks' PMA, and to analyse variables associated with both outcomes. DESIGN: Retrospective cohort with data retrieved from an ongoing national registry. SETTING: 19 Brazilian university public hospitals. PATIENTS: Infants born between 2010 and 2019 with 23-31 weeks and birth weight 400-1499 g. MAIN OUTCOME MEASURES: Temporal trend was evaluated by Prais-Winsten model and variables associated with BPD in survivors or BPD or death were analysed by logistic regression. RESULTS: Of the 11 128 included infants, BPD in survivors occurred in 22%, being constant over time (annual per cent change (APC): -0.80%; 95% CI: -2.59%; 1.03%) and BPD or death in 45%, decreasing over time (APC: -1.05%; 95% CI: -1.67%; -0.43%). Being male, small for gestational age, presenting with respiratory distress syndrome, air leaks, needing longer duration of mechanical ventilation, presenting with treated patent ductus arteriosus and late-onset sepsis were associated with an increase in the chance of BPD. For the outcome BPD or death, maternal bleeding, multiple gestation, 5-minute Apgar <7, late-onset sepsis, necrotising enterocolitis and intraventricular haemorrhage were added to the variables reported above as increasing the chance of the outcome. CONCLUSION: The frequency of BPD in survivors was constant and BPD or death decreased by 1.05% at each study year. These results show some improvement in perinatal care in Brazilian units which resulted in a reduction of BPD or death, but further improvements are still needed to reduce BPD in survivors.

RESUMO

OBJECTIVES: This study aimed to analyze, in the São Paulo state of Brazil, time trends in prevalence, neonatal mortality, and neonatal lethality of central nervous system congenital malformations (CNS-CM) between 2004 and 2015. METHODS: Population-based study of all live births with gestational age ≥22 weeks and/or birthweight ≥400 g from mothers living in São Paulo State, during 2004-2015. CNS-CM was defined by the presence of International Classification Disease 10th edition codes Q00-Q07 in the death and/or live birth certificates. CNS-CM was classified as isolated (only Q00-Q07 codes), and non-isolated (with congenital anomalies codes nonrelated to CNS-CM). CNS-CM associated neonatal death was defined as death between 0 and 27 days after birth in infants with CNS-CM. CNS-CM prevalence, neonatal mortality, and lethality rates were calculated, and their annual trends were analyzed by Prais-Winsten Model. The annual percent change (APC) with 95% confidence interval (95%CI) was obtained. RESULTS: 7,237,628 live births were included in the study and CNS-CM were reported in 7526 (0.1%). CNS-CM associated neonatal deaths occurred in 2935 (39.0%). Isolated CNS-CM and non-isolated CNS-CM were found respectively in 5475 and 2051 livebirths, with 1525 (28%) and 1410 (69%) neonatal deaths. CNS-CM prevalence and neonatal lethality were stationary, however neonatal mortality decreased (APC -1.66; 95%CI -3.09 to -0.21) during the study. For isolated CNS-CM, prevalence, neonatal mortality, and lethality decreased over the period. For non-isolated CNS-CM, the prevalence increased, neonatal mortality was stationary, and lethality decreased during the period. The median time of CNS-CM associated neonatal deaths was 18 h after birth. CONCLUSIONS: During a 12-year period in São Paulo State, Brazil, neonatal mortality of infants with CNS-CM in general and with isolated CNS-CM showed a decreasing pattern. Nevertheless CNS-CM mortality remained elevated, mostly in the first day after birth.

RESUMO

Objetivo: refletir sobre o acesso a serviços de saúde para infertilidade e reprodução humana assistida durante o período da pandemia de COVID-19, na perspectiva da justiça reprodutiva. Metodologia: utilizou-se dados do inquérito online da pesquisa Pandemia de COVID-19e práticas reprodutivas de mulheres no Brasil, que obteve 8.313 respostas de mulheres residentes em todas as regiões do país, de 18 anos ou mais. O questionário autoaplicável circulou entre julho e outubro de 2021, contendo questões fechadas e abertas. A análise descritiva das respostas objetivas de 242 mulheres que referiram buscar atendimento para infertilidade contou com o cálculo de frequências simples das variáveis. Já os textos escritos nos espaços abertos do questionário foram submetidos à análise temática. Resultados: o estudo verificou a existência de barreiras institucionais e não institucionais para os cuidados da infertilidade, ambas incrementadas pela pandemia. Conclusão: recomenda-se a efetivação de política pública que garanta acesso pleno a todas as pessoas, haja vista que o tratamento para infertilidade e reprodução assistida tende a se restringir a mulheres cisgênero, de camadas médias e altas, mais escolarizadas e majoritariamente brancas.


Objective: to critically examine access to health services for infertility and assisted human reproduction during the COVID-19 pandemic, emphasizing the perspective of reproductive justice. Methods: data for analysis were derived from the online survey titled COVID-19 Pandemic and Women's Reproductive Practices in Brazil, garnering 8,313 responses from women aged 18 years or older residing in all regions of the country. The self-administered questionnaire circulated from July to October 2021 and comprised both closed and open-ended questions. Descriptive analysis of the objective responses obtained from 242 women actively seeking infertility care involved the calculation of simple frequencies for relevant variables. Responses provided in the open-ended sections of the questionnaire underwent thematic analysis. Results: revealed the presence of both institutional and non-institutional barriers to infertility care, with a notable exacerbation during the pandemic. Conclusion: given that infertility and assisted reproduction treatment predominantly cater to cisgender women from middle and upper socio-economic strata, characterized by higher education levels and mostly white, there is a compelling need for the implementation of public policies that ensure equitable access for all individuals.

RESUMO

Like other phthalates, diethyl phthalate (DEP) is considered as a contaminant of emerging concern (CEC) due to its ease in migrating from a package to water and food, and hence contaminate consumers, being metabolized and excreted in the urine. Its presence has a negative impact on aquatic ecosystems, especially with respect to disruption of the endocrine system and to reproductive disorders in humans. It mainly enters water bodies via sewage effluents from effluent treatment plants, due to its incomplete or inefficient removal. The objective of this work was to evaluate the toxicity of DEP at different trophic levels and to analyze data on the incidence and concentration of DEP according to its solubility. The concentrations ranged from 12.5 mg L-1 to 500 mg L-1 considering the response for toxicity at each trophic level and to determine the lethal concentration in 50% of the following organisms (LC50) (in mg L-1): Lactuca sativa seeds, Artemia salina Leach nauplii and Zebrafish embryo larval stage (Danio rerio), being 41,057.58 after 120 h; 401.77 after 48 h; and 470 after 96 h of exposure, respectively. As expected, higher organisms were more affected even at low concentrations, which shows the anthropological contribution of CECs to water bodies.

RESUMO

OBJECTIVES: The Global Leadership Initiative on Malnutrition (GLIM) criteria establish a diagnosis of malnutrition based on the presence of at least one phenotypic and one etiologic criterion. This study aimed to assess the concurrent and predictive validity of the GLIM criteria in hospitalized cancer patients. METHODS: This is an observational retrospective study, including 885 cancer patients, ages >18 y, admitted to a medical oncology inpatient unit between 2019 and 2020. All patients at risk for malnutrition according to the Nutritional Risk Screening 2002 score were assessed by the subjective global assessment (SGA) and 14 different combinations of the GLIM criteria. The SGA was considered the gold standard for assessing the concurrent validity of the GLIM combinations. For a subsample of patients with data available on inflammatory markers (n = 198), the serum albumin and C-reactive protein were included in the combinations as etiologic criteria. The predictive validity of the different combinations was tested using the occurrence of surgical complications as the clinical outcome. The sensitivity and specificity values were calculated to assess the concurrent validity, univariate and multivariate logistic regression models were used to test predictive validity. Adequate concurrent and predictive validity were determined as sensitivity and specificity values >80% and odds ratio values ≥2.0, respectively. RESULTS: The median age of the patients was 61.0 y (interquartile range = 51.0-70.0). Head and neck cancer was the prevailing diagnosis and 375 patients were at nutritional risk. According to the SGA, 173 (26.1%) patients were malnourished (SGA categories B or C) and the prevalence of malnutrition ranged from 3.9% to 30.0%, according to the GLIM combinations. None of the tested combinations reached adequate concurrent validity; however, the presence of malnutrition according to four combinations independently predicted surgical complications. CONCLUSIONS: The predictive validity of the GLIM was satisfactory in surgical cancer patients.

RESUMO

INTRODUCTION: Abdominal obesity is a pattern of obesity that has been considered a public health problem. Physical activity is considered an important factor for the prevention of abdominal obesity. Increased time in sedentary behavior has been associated with negative health outcomes, including abdominal obesity. OBJECTIVE: The aim of this study was to investigate which combination of leisure-time physical activity and sedentary behavior contributes most to the prevention of abdominal obesity in adults participating in ELSA-Brasil (Longitudinal Study of Adult Health). METHODS: The study was cross-sectional and participants from the first follow-up of the ELSA-Brasil cohort (2012-2014) were analyzed. The independent variables were physical activity, assessed by IPAQ, and sedentary behavior, assessed by a standard questionnaire applied in ELSA-Brasil; the dependent variable was abdominal obesity, determined by waist circumference. The covariates analyzed were the following: age, education, binge drinking, smoking and menopause. The associations between the dependent variable and the independent variables were analyzed using logistic regression. The odds ratio with 95 CI% was estimated. RESULTS: For men, the combinations were more significant when they were more physically active and spent less time on the sedentary behaviors analyzed, on both a weekday and a weekend day. For menopausal women, both younger and older, all associations of the combinations between sufficient leisure-time physical activity and little time spent in sedentary behaviors contributed to the prevention of abdominal obesity. In non-menopausal women, positive associations were observed in almost all combinations between leisure-time physical activity and sedentary behaviors, with some results that were not statistically significant among younger women. CONCLUSIONS: Our results showed that being sufficiently active and reducing the time spent in sedentary behavior was the combination that contributed the most to the prevention of abdominal obesity, both in men and women.

RESUMO

Understanding the relationship between infectious disease outbreaks and natural disasters is important in developing response and disaster risk reduction strategies. The aim of this study was to identify outbreaks associated with natural disasters during the past 20 y, and outline risk factors and mechanisms for postdisaster outbreaks. Review of the international disaster database (EM-DAT) and systematic review of the literature were conducted. The records of disaster events in EM-DAT during the past 20 y were screened. A literature search was carried out in the databases PubMed and Embase. Articles in English language published between 2000 and 2020 were searched. Data were extracted from articles and Narrative synthesis was used to summarize the findings. We found 108 events associated with epidemics, the majority being floods. We found 36 articles, most of them focused on outbreaks after floods. Risk factors and mechanisms that contributed to the outbreaks were mainly related to the consequences of disaster and its impact on the environment and living conditions of population. Infrastructure readiness and postdisaster measures play important roles in controlling the spread of epidemics after natural disasters. More evidence and research are required for better understanding of the association between natural disasters and infectious diseases outbreaks.

RESUMO

OBJECTIVE: Measuring exhaled carbon dioxide (ECO2) during non-invasive ventilation at birth may provide information about lung aeration. However, the International Liaison Committee on Resuscitation (ILCOR) only recommends ECO2 detection for confirming endotracheal tube placement. ILCOR has therefore prioritised a research question that needs to be urgently evaluated: 'In newborn infants receiving intermittent positive pressure ventilation by any non-invasive interface at birth, does the use of an ECO2 monitor in addition to clinical assessment, pulse oximetry and/or ECG, compared with clinical assessment, pulse oximetry and/or ECG only, decrease endotracheal intubation in the delivery room, improve response to resuscitation, improve survival or reduce morbidity?'. DESIGN: Systematic review of randomised and non-randomised studies identified by Ovid MEDLINE, Embase and Cochrane CENTRAL search until 1 August 2022. SETTING: Delivery room. PATIENTS: Newborn infants receiving non-invasive ventilation at birth. INTERVENTION: ECO2 measurement plus routine assessment compared with routine assessment alone. MAIN OUTCOME MEASURES: Endotracheal intubation in the delivery room, response to resuscitation, survival and morbidity. RESULTS: Among 2370 articles, 23 were included; however, none had a relevant control group. Although studies indicated that the absence of ECO2 may signify airway obstruction and ECO2 detection may precede a heart rate increase in adequately ventilated infants, they did not directly address the research question. CONCLUSIONS: Evidence to support the use of an ECO2 monitor to guide non-invasive positive pressure ventilation at birth is lacking. More research on the effectiveness of ECO2 measurement in addition to routine assessment during non-invasive ventilation of newborn infants at birth is needed.

RESUMO

OBJECTIVE: This review aimed to assess the evidence available in the literature about the protocols for using peanut ball (PB) in women during labour and delivery. DATA SOURCES: A systematic search was carried out by 2 independent researchers in the PubMed/MedLine, Web of Science, Embase, Cochrane and Scopus databases, and the reference lists were scanned for additional articles. STUDY SELECTION: Search terms employed were selected from MeSH (Medical Subject Headings) and DeCS (Descriptors in Health Sciences) and combined in each database: "Pregnant Women" AND "Peanut Ball", "Peanut Ball" AND "Labor, Obstetric", as well as "Peanut Ball" AND "Parturition". There were no limits regarding the publication period or language. Studies that answered the following question were included: What are the protocols for the use of the PB in women during labour and childbirth described in the literature? Secondary studies were excluded. Disagreements were resolved by a third researcher. DATA EXTRACTION: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement guided this review. The authors prepared a standardized data extraction sheet to extract data and used the Mendeley software to organize the analyzed studies. DATA SYNTHESIS: Ten studies made up the final sample of this review. Eight articles presented the protocol for using the PB: 2 studies included it after epidural analgesia and removed it at complete cervical dilation and effacement; 4 addressed the frequency of position changes during labour; and 3 reported data on maternal positions that were adopted. Five studies showed lower rates of cesarean delivery, and 2 reported that PB reduces the length of labour. Only 1 article associated the use of PB with the reduction of instrumental deliveries and perineal lacerations. One study showed a positive evaluation of parturients regarding the use of PB. CONCLUSION: PB was associated with a reduction in cesarean and instrumental deliveries, and the length of labour. Despite its benefits, there is no standardized protocol for the use of PB, preventing it from predicting outcomes with its use. PROSPERO ID: CRD42023392238.

RESUMO

Introduction: Premature birth, perinatal asphyxia, and infections are the main causes of neonatal death. Growth deviations at birth also affect neonatal survival according to week of gestation at birth, particularly in developing countries. The purpose of this study was to verify the association between inappropriate birth weight and neonatal death in term live births. Methods: This is an observational follow-up study with all term live births from 2004 to 2013 in Sao Paulo State, Brazil. Data were retrieved with the deterministic linkage of death and birth certificates. The definition of very small for gestational age (VSGA) and very large for gestational age (VLGA) used the 10th percentile of 37 weeks and the 90th percentile of 41 weeks + 6 days, respectively, based on the Intergrowth-21st. We measured the outcome in terms of time to death and the status of each subject (death or censorship) in the neonatal period (0-27 days). Survival functions were calculated using the Kaplan-Meier method stratified according to the adequacy of birth weight into three groups (normal, very small, or very large). We used multivariate Cox regression to adjust for proportional hazard ratios (HRs). Results: The neonatal death rate during the study period was 12.03/10,000 live births. We found 1.8% newborns with VSGA and 2.7% with VLGA. The adjusted analysis showed a significant increase in mortality risk for VSGA infants (HR = 4.25; 95% CI: 3.89-4.65), independent of sex, 1-min Apgar score, and five maternal factors. Discussion: The risk of neonatal death in full-term live births was approximately four times greater in those with birth weight restriction. The development of strategies to control the factors that determine fetal growth restriction through planned and structured prenatal care can substantially reduce the risk of neonatal death in full-term live births, especially in developing countries such as Brazil.
