Effect of hyperchloremia on mortality of pediatric trauma patients: a retrospective cohort study

ABSTRACT BACKGROUND: Hyperchloremia is often encountered due to the frequent administration of intravenous fluids in critically ill patients with conditions such as shock or hypotension in the pediatric intensive care unit, and high serum levels of chloride are associated with poor clinical outcomes. OBJECTIVES: This study aimed to determine the association between hyperchloremia and in-hospital mortality in pediatric patients with major trauma. DESIGN AND SETTING: This retrospective cohort study was conducted at a tertiary university hospital in Turkey. METHODS: Data were collected between March 2020 and April 2022. Patients aged 1 month to 18 years with major trauma who received intravenous fluids with a concentration > 0.9% sodium chloride were enrolled. Hyperchloremia was defined as a serum chloride level > 110 mmol/L. Clinical and laboratory data were compared between the survivors and nonsurvivors. RESULTS: The mortality rate was 23% (n = 20). The incidence of hyperchloremia was significantly higher in nonsurvivors than in survivors (P = 0.05). In multivariate logistic analysis, hyperchloremia at 48 h was found to be an independent risk factor for mortality in pediatric patients with major trauma. CONCLUSIONS: In pediatric patients with major trauma, hyperchloremia at 48-h postadmission was associated with 28-day mortality. This parameter might be a beneficial prognostic indicator.

Exceso de mortalidad en población en edad de trabajar en nueve países de Latinoamérica, año 2020 / Excess mortality in 2020 in the working-age population of nine Latin American countries / Excesso de mortalidade na população em idade ativa em nove países da América Latina no ano de 2020

RESUMEN Objetivo. Estimar el impacto de la pandemia de la COVID-19 durante el año 2020, a través del exceso de mortalidad por todas las causas y los años potenciales de vida laboral perdidos en la población en edad de trabajar, de una selección de países latinoamericanos y el Caribe. Métodos. Estudio basado en datos de defunciones por todas las causas entre 15 y 69 años, procedentes principalmente de los Institutos Nacionales de Estadísticas. Se estimaron defunciones esperadas a partir de las registradas entre 2015 y 2019. El exceso de mortalidad fue estimado a través del indicador P, la razón de mortalidad estandarizada (RME) y los años potenciales de vida laboral perdidos (AVLP) hasta los 70 años. Resultados. El exceso de defunciones en Brasil, Bolivia, Chile, Colombia, Costa Rica, Cuba, México, Perú y República Dominicana sumó 426 978 (279 591 en hombres y 147 438 en mujeres), lo que representó una pérdida de 5 710 048 (3 738 775 en hombres y 1 971 273 en mujeres) de APVLP. La mortalidad observada fue significativamente superior a la esperada en todos los países, menos República Dominicana. Conclusiones. El impacto de la COVID-19 en la población en edad de trabajar tendrá un impacto profundo en la situación socioeconómica. El recuento oportuno del exceso de muertes resulta útil y puede ser usado como un sistema de alerta temprana para monitorizar la magnitud de los brotes de COVID-19. La monitorización del exceso de mortalidad en personas en edad de trabajar, realizada por el Observatorio Iberoamericano de Seguridad y Salud en el Trabajo permite evaluar con mayor exactitud la carga social y económica de la COVID-19.

ABSTRACT Objective. Estimate the impact of the COVID-19 pandemic in 2020, through excess all-cause mortality and potential years of productive life lost (YPLL) in the working-age population, in selected Latin American and Caribbean countries. Methods. Study based on data on deaths from all causes from age 15 to 69 years, mainly from national institutes of statistics. Estimates of expected deaths were based on reported deaths from 2015 to 2019. Excess mortality was estimated using the P indicator, standardized mortality ratio (SMR), and potential YPLL up to age 70 years. Results. Excess deaths in Brazil, Bolivia, Chile, Colombia, Costa Rica, Cuba, the Dominican Republic, Mexico, and Peru totaled 426 978 (279 591 men and 147 438 women), representing a potential loss of 5 710 048 (3 738 775 in men and 1 971 273 in women) years of productive life. Observed mortality was significantly higher than expected in all countries except the Dominican Republic. Conclusions. COVID-19 in the working-age population will have a profound impact on socio-economic conditions. Timely counting of excess deaths is useful and can be used as an early warning system to monitor the magnitude of COVID-19 outbreaks. Monitoring of excess mortality in working-age people by the Ibero-American Observatory on Safety and Health at Work enables more accurate assessment of the social and economic burden of COVID-19.

Incidence, characteristics and long-term outcomes of patients with diabetic ketoacidosis: a prospective prognosis cohort study in an emergency department

ABSTRACT BACKGROUND: Diabetic ketoacidosis is the most frequent hyperglycemic complication in the evolution of diabetes mellitus. Common precipitating factors include newly diagnosed diabetes mellitus, noncompliance with therapy and infections. However, few studies have been conducted in Brazil and none were prospective in design. OBJECTIVE: To describe the incidence, clinical and laboratory characteristics and precipitating factors of diabetic ketoacidosis among emergency department patients in a tertiary-level teaching hospital in Brazil. We also aimed to identify immediate and long-term mortality within two years. DESIGN AND SETTING: Prospective prognosis cohort study conduct at a tertiary-level teaching hospital in São Paulo, Brazil. METHODS: All patients > 12 years old presenting diabetic ketoacidosis who were admitted to the emergency department from June 2015 to May 2016 were invited to participate. RESULTS: The incidence of diabetic ketoacidosis per 1,000 admissions was 8.7. Treatment noncompliance and infection were the most common causes of diabetic ketoacidosis. The immediate mortality rate was 5.8%, while the six-month, one-year and two-year mortality rates were 9.6%, 13.5% and 19.2%, respectively. Death occurring within two years was associated with age, type 2 diabetes, hypoalbuminemia, infection at presentation and higher sequential organ failure assessment (SOFA) score at admission. CONCLUSIONS: Diabetic ketoacidosis among patients presenting to the emergency department was relatively frequent in our hospital. Treatment noncompliance and infection were major precipitating factors and presence of diabetic ketoacidosis was associated with immediate and long-term risk of death.

Fetoscopic laser photocoagulation for twin-to-twin transfusion syndrome treatment: initial experience in tertiary reference center in Brazil

OBJECTIVE: To evaluate the initial maternal and perinatal outcomes of fetoscopic laser photocoagulation for the treatment of twin-to-twin transfusion syndrome (TTTS) in a referral center in Brazil. METHODS: This prospective observational study analyzed 24 fetoscopic laser photocoagulation procedures at 18–26 weeks of gestation. TTTS severity was determined using the Quintero classification. Blood vessels that crossed the interamniotic membrane were nonselectively photocoagulated. The χ2 test and Mann-Whitney U test were used for the statistical analysis. RESULTS: The mean (±standard deviation) age of pregnant women, gestational age at surgery, surgical time, gestational age at birth, and newborn weight were 32.2±4.1 years, 20.7±2.9 weeks, 51.8±16.7 minutes, 30.5±4.1 weeks, and 1,531.0±773.1 g, respectively. Using the Quintero classification, there was a higher percentage of cases in stage III (54.2%), followed by stages IV (20.8%), II (16.7%), and I (8.3%). Ten (41.7%) donor fetuses died and 14 (58.3%) donor fetuses survived until the end of gestation. Placental insertion location (anterior vs. posterior) did not affect the incidence of iatrogenic septostomy, surface bleeding, and premature rupture of membranes until the end of gestation. The death rate of donor and recipient fetuses before 24th gestational week increased with severity of TTTS. CONCLUSION: The maternal and perinatal outcomes resulting from the implementation of a new minimally invasive surgical technique are in line with those obtained in major centers worldwide, considering the learning curves and infrastructures.

Growth and mortalities of the pink-shrimp Farfantepenaeus brasiliensis Latreille, 1970 and F. paulensis Pérez-Farfante 1967 in Southeast Brazil

From July, 1999 until July, 2001 data from the pink-shrimp Farfantepenaeus brasiliensis Latreille, 1970 and F. paulensis Pérez-Farfante, 1967 fishery were collected from trawling by the fishing fleet based in Santos/Guarujá-SP. Growth and mortalities of these species were studied. F. brasiliensis and F. paulensis have longevity of 2 years and growth estimates of L FONT FACE=Symbol>¥ /FONT> = 29.0 cm and k = 1.24 year-1 for F. brasiliensis and L FONT FACE=Symbol>¥ /FONT> = 27.5 cm and k = 1.34 year-1 for F. paulensis. Females reach bigger lengths than males in both species. Natural mortalities (M) were 1.80 and 1.90 year-1 and fishing mortalities (F) were 4.7 and 6.8 year-1 for F. brasiliensis and F. paulensis, respectively. Survival rates are S = 0.15% and 0.02% for F. brasiliensis and F. paulensis, respectively, which are usually low values for shrimps.

De Julho de 1999 a Julho de 2001, foram coletados dados das pescarias comerciais do camarão-rosa Farfantepenaeus brasiliensis Latreille, 1970 e F. paulensis Pérez-Farfante, 1967, relativos à frota pesqueira de arrasto, sediada em Santos (SP). Estimativas dos parâmetros de crescimento e de mortalidades foram calculadas. Farafantepenaeus brasiliensis e F. paulensis são espécies de crescimento rápido e vida curta, com longevidade de 2 anos (L FONT FACE=Symbol>¥ /FONT> = 29,0 cm e k = 1,24 ano-1 para F. brasiliensis; L FONT FACE=Symbol>¥ /FONT> = 27,5 cm e k = 1,34 ano-1 para F. paulensis). As fêmeas atingem tamanhos maiores que os machos para ambas espécies. As mortalidades naturais foram estimadas em M = 1,80 ano-1 e 1,90 ano-1 e as mortalidades por pesca F = 4,7 ano-1 e 6,8 ano-1 para F. brasiliensis e F. paulensis, respectivamente. As taxas de sobrevivência foram calculadas em S = 0,15% para F. brasilensis e S = 0,02% para F. paulensis, valores usualmente baixos para camarões.

Spontaneous Remission of Congenital Leukemia-One Case Report / 中华围产医学杂志

Objective To discuss the clinical features and possible mechanisms of congenrtal leuleemia spontaneous remission. Methods By means of literature review, 17 cases with spontaneous remission of congenital leukemia were retrospectively analyzed. Results Among the 17 patients, 8 were persistent remission(47%), 9 had late relapses(53%). Neither initial white cell count nor bone marrow involvement was associated with late relapses. 5 cases(29%) had abnormal karyotype and gene rearrangment,11q23 translocation indicated poor prognosis. Conclusions Conservative treatment can be given unless there was evidence of progressive leukemia. Because of occasional late relapses, long term follow-up was recommended. The detection of karyotype and gene rearrangment was a powerful prognostic tool available.
