Hand Hygiene indicators and strategies in Medical Day Care in Salvador, BA / Indicadores y estrategias de Higiene de las Manos en Centros de Día / Indicadores e estratégias da higiene das mãos em Hospital Dia

Objective: To analyze hand hygiene (HH) adherence indicators among healthcare professionals in a medical day care (MDC) and present strategies used to encourage this practice. Method: A cross-sectional and descriptive study was conducted in an MDC located in Salvador, Bahia. Data collection consisted of document analysis and internal audit data on HH practice from 2016 to 2023. Results: HH adherence rates ranged from 39.4 to 81.4%, with an average of 63.9%. Among the evaluated healthcare professionals, nurses showed the highest HH adherence (74.3%), followed by nursing technicians (71.1%) and physicians (50%). Multimodal strategies to encourage HH in this service included HH training, with systematic evaluation con-ducted by nursing coordinators. Conclusion: The HH adherence rates presented are higher than those reported in the literature but below the standar-dized goal of 70% in the MDC studied, confirming that the implementation of this apparently simple practice is a complex, multi-causal issue that requi-res coordination between management policies as well as scientific knowledge in building a culture in favor of this practice in healthcare organizations.

Histological Alterations in Placentas of Pregnant Women with SARS-CoV-2 Infection: A Single-Center Case Series.

This study aimed to investigate the histopathological changes associated with SARS-CoV-2 infection in placentas. A case series of anatomopathological analysis was conducted on the placentas of pregnant women with SARS-CoV-2 who delivered between March and December 2020 at Santo Amaro Hospital (HSA) in Salvador, Brazil. Out of the 29 placentas examined, the median weight was 423.0 (IQR: 385.0-521.0) g. Among them, 58.3% (n = 14) had inadequate weight relative to the newborn's weight. The histopathological findings revealed that 86.2% (n = 25) of the placentas had poorly defined lobes, and the fetal and maternal surface color was normal in 89.7% (n = 26) and 93.1% (n = 27), respectively. Additionally, 51.7% (n = 15) of the umbilical cords displayed hypercoiling. The most frequent microscopic finding was infarction, present in 35.3% (n = 6) of the cases, followed by 11.8% (n = 2) for each of chorioamnionitis, chronic villitis, focal perivillositis, and laminar necrosis. Analysis of the umbilical cords identified 23.5% (n = 4) cases of intervillous thrombosis, while amnion analysis showed 13.8% (n = 4) cases of squamous metaplasia. Extraplacental membrane examination revealed fibrin deposition in 93.1% (n = 27) of the cases, necrosis in 62.0% (n = 18), calcifications in 51.7% (n = 15), cysts in 37.9% (n = 11), neutrophilic exudate in 17.2% (n = 5), thrombosis in 13.7% (n = 4), and delayed placental maturation in 6.9% (n = 2). All analyzed placentas exhibited histopathological changes, primarily vascular and inflammatory, which indicate SARS-CoV-2 infection in term pregnancies. These alterations could be associated with impaired placental function, fetal growth restriction, preeclampsia, and prematurity. However, further prospective studies are required to validate the type, prevalence, and prognosis of each of these changes.

SARS-CoV-2 infection in pregnant women and newborns in two maternity hospitals in Salvador-Bahia, Brazil.

The outbreak of the new coronavirus (SARS-CoV-2) causing the coronavirus disease (COVID-19) has spread globally. As of June 18, 2020, a high maternal mortality rate due to SARS-CoV-2 infections was identified in Brazil, representing most of the world cases at that time. An observational, cross-sectional study was performed with pregnant women admitted in two maternity hospitals located in Salvador/Bahia and their newborns, from May 24th up to July 17th of 2020. Among 329 pregnant women enrolled at hospital admission, a high prevalence (n=28; 8.5%) of pregnant women with COVID-19 was observed, as well as a high proportion of asymptomatic cases (n=19; 67.9%). Two newborns had detectable SARS-CoV-2 but evolved without abnormalities. This data highlight the importance of identifying pregnant women with COVID-19 for proper isolation measures to prevent in-hospital transmission.

Incidência de infecção de sítio cirúrgico em hospital dia: coorte de 74213 pacientes monitorados / Incidence of infection of surgical site in hospital day: cohort of 74213 patients monitored / Incidencia de la infección del sitio quirúrgico en el día de hospital: cohorte de 74213 pacientes monitoreados

Objetivos: Descrever a incidência de infecção do sítio cirúrgico (ISC) em seguimento após alta em hospital dia (HD) e comparar esses indicadores com dados de hospitais convencionais. Método: Estudo de coorte histórica composto de 74.213 pacientes operados e monitorados num HD de Salvador (BA), entre 2012 e 2017. Resultados: No período estudado, o sistema de vigilância do HD monitorou 85,1% dos pacientes após a alta e foi identificada incidência total de ISC de 0,3%, com variação de 0,2 a 0,4% entre os anos, taxas estatisticamente menores do que as reportadas para ISC em regime de internação hospitalar. Conclusão: Os indicadores de ISC revelados neste estudo ratificam que a modalidade da assistência cirúrgica ambulatorial porta menor risco de aquisição de infecção para os pacientes operados, quando comparados com os dados de infecção cirúrgica de pacientes em hospitais convencionais. Entretanto, torna-se indispensável um sistema de seguimento dos pacientes após a alta, no sentido de evitar a subnotificação e os sub-registros dos dados de ISC, pois na ausência de ambos se podem ocultar riscos e identificar taxas irreais

Objectives: To describe the incidence of surgical site infection (SSI) after discharge from a Daycare Unit (DU) and to compare these indicators with data from conventional hospitals. Method: This is a historical cohort study including 74,213 patients who underwent surgery and were monitored at a DU in Salvador (Bahia State, Brazil), between 2012 and 2017. Results: During the studied period, the DU surveillance system monitored 85.1% of patients after discharge. We found a total SSI incidence of 0.3%, varying between 0.2 and 0.4% in those years. These rates were statistically lower than those reported for SSI in hospitalized patients. Conclusion: The SSI indicators revealed in this study confirm that outpatient surgical care poses lower risks of infection acquisition for the operated patients, when compared with surgical infection data of patients from conventional hospitals. However, a follow-up system for patients after discharge is essential to avoid sub-reporting and sub-records regarding SSI data, considering that risks can be hidden and unrealistic rates can be identified in their absence.

Objetivos: Describir la incidencia de la infección del sitio quirúrgico (ISQ), después del alta del centro de día (CD) y comparar esos indicadores con los datos de hospitales convencionales. Método: Estudio de cohorte histórico con 74,213 pacientes operados y monitoreados en un CD en Salvador (Bahia, Brasil), entre 2012 y 2017. Resultados: Durante el período estudiado, el sistema de vigilancia del CD monitorizó el 85,1% de los pacientes después del alta, y se identificó una incidencia total de la ISQ del 0,3%, que varía desde el 0,2% hasta el 0,4% entre los años. Esas tasas son estadísticamente más bajas que las reportadas para ISQ bajo el régimen de hospitalización integral. Conclusión: Los indicadores de la ISQ revelados en este estudio confirman que la modalidad de atención quirúrgica ambulatoria conlleva un menor riesgo de adquisición de infección para los pacientes operados, en comparación con los datos de infección quirúrgica de pacientes en hospitales convencionales. Sin embargo, es indispensable un sistema de seguimiento para los pacientes después del alta hospitalaria, para evitar el sub-reporto y los subregistros de los datos de la ISQ, ya que en ausencia de ambos se pueden ocultar riesgos y se pueden identificar tasas poco realistas.

Breastfeeding in children born small for gestational age and future nutritional and metabolic outcomes: a systematic review / Aleitamento materno em crianças nascidas pequenas para idade gestacional e os desfechos nutricionais e metabólicos futuros: revisão sistemática

Abstract Objective: To systematically review evidence related to nutritional and cardiometabolic outcomes in children born at term and small for gestational age and the association with breastfeeding. Source of data: Two independent reviewers searched the MEDLINE, LILACS, SciELO, and Embase databases without time or language restrictions. The PRISMA tool was used, and studies that evaluated infants born at term and small for gestational age, breastfed, and with an evaluation of cardiometabolic outcomes were included. Studies with preterm infants, those that did not have information on breastfeeding, and those with lack of evaluation of the outcome variables were excluded. Also excluded were review articles, editorials, and series of cases. Summary of data: Only seven articles were found that met the abovementioned criteria. There was a great variability in the type of evaluation, as well as in the age of these children. It was demonstrated that breastfeeding promoted growth without body composition alteration and without increased insulin resistance in children with exclusive breastfeeding, when compared to children receiving a higher calorie formula, except for one article that observed an increase in fat mass in exclusively breastfed children. Conclusion: Breastfeeding seems to be a safe feeding practice for infants born at term and small for gestational age, showing no association with deleterious short-term outcomes. Breastfeeding stimulation in these populations seems to be a way of preventing the health problems associated with the high risk of chronic noncommunicable diseases and obesity.

Resumo Objetivo: Revisar sistematicamente as evidências relacionadas aos desfechos nutricionais e cardiometabólicos em crianças nascidas a termo e pequenas para idade gestacional e a relação com o aleitamento materno. Fonte de dados: Dois revisores independentes fizeram buscas nas bases de dados MEDLINE,LILACS, SciELO, EMBASE sem restrições de tempo ou idioma. Foi usada a ferramenta PRISMA sendo incluídos estudos que avaliaram crianças nascidas a termo e pequenas para idade gestacional, amamentadas e com avaliação dos desfechos cardiometabólicos. Foram excluídos estudos com prematuros, aqueles que não trouxessem informação do aleitamento materno, ausência de avaliação das variáveis de desfecho. Também não foram incluídos artigos de revisão, editorial e série de casos. Síntese dos dados: Foram encontrados apenas sete artigos que preencheram os critérios citados acima. Houve uma grande variabilidade na forma de avaliação, assim como na idade dessas crianças. Foi evidenciado que o aleitamento materno promoveu crescimento sem alteração de composição corporal e sem resistência insulínica aumentada nas crianças com aleitamento materno exclusivo, quando comparadas com crianças que receberam fórmula láctea de maior teor calórico, exceto por um artigo que observou aumento de massa gorda nos amamentados exclusivamente. Conclusão: Aleitamento materno parece ser uma forma segura de alimentação para crianças nascidas a termo e pequenas para idade gestacional sem associação com desfechos deletérios em curto prazo. O estímulo ao aleitamento materno nessas populações parece ser um caminho de prevenção aos agravos à saúde associados ao alto risco de doenças crônicas não transmissíveis e à obesidade.

Early neonatal deaths associated with perinatal asphyxia in infants ≥2500g in Brazil / Óbitos neonatais precoces associados à asfixia perinatal em neonatos ≥2500g no Brasil

Abstract Objective: To assess the annual burden of early neonatal deaths associated with perinatal asphyxia in infants weighing ≥2500 g in Brazil from 2005 to 2010. Methods: The population study enrolled all live births of infants with birth weight ≥2500 g and without malformations who died up to six days after birth with perinatal asphyxia, defined as intrauterine hypoxia, asphyxia at birth, or meconium aspiration syndrome. The cause of death was written in any field of the death certificate, according to International Classification of Diseases,10th Revision (P20.0, P21.0, and P24.0). An active search was performed in 27 Brazilian federative units. The chi-squared test for trend was applied to analyze early neonatal mortality ratios associated with perinatal asphyxia by study year. Results: A total of 10,675 infants weighing ≥2500 g without malformations died within six days after birth with perinatal asphyxia. Deaths occurred in the first 24 h after birth in 71% of the infants. Meconium aspiration syndrome was reported in 4076 (38%) of these deaths. The asphyxia-specific early neonatal mortality ratio decreased from 0.81 in 2005 to 0.65 per 1000 live births in 2010 in Brazil (p < 0.001); the meconium aspiration syndrome-specific early neonatal mortality ratio remained between 0.20 and 0.29 per 1000 live births during the study period. Conclusions: Despite the decreasing rates in Brazil from 2005 to 2010, early neonatal mortality rates associated with perinatal asphyxia in infants in the better spectrum of birth weight and without congenital malformations are still high, and meconium aspiration syndrome plays a major role.

Resumo Objetivo: Avaliar a taxa anual de óbitos neonatais precoces associados à asfixia perinatal em neonatos de peso ≥ 2.500 g no Brasil de 2005 a 2010. Métodos: A população do estudo envolveu todos os nascidos vivos de neonatos com peso ao nascer ≥ 2.500 g e sem malformações que morreram até seis dias após o nascimento por asfixia perinatal, definida como hipóxia intrauterina, asfixia no nascimento ou síndrome de aspiração de mecônio. A causa do óbito foi escrita em qualquer linha do atestado de óbito, de acordo com a Classificação Internacional de Doenças, 10a Revisão (P20.0, P21.0 e P24.0). Foi feita uma pesquisa ativa em 27 unidades federativas brasileiras. O teste qui-quadrado de tendência foi aplicado para analisar os índices de mortalidade neonatal associados a asfixia perinatal até o ano do estudo. Resultados: Morreram 10.675 neonatos com peso ≥ 2.500 g sem malformações até 0-6 dias após o nascimento por asfixia perinatal. Os óbitos ocorreram nas primeiras 24 horas após o nascimento em 71% dos neonatos. A síndrome de aspiração de mecônio foi relatada em 4.076 (38%) dos óbitos. O índice de mortalidade neonatal precoce relacionada à asfixia caiu de 0,81 em 2005 para 0,65 por 1.000 nascidos vivos em 2010 no Brasil (p < 0,001); o índice de mortalidade neonatal precoce relacionada a síndrome de aspiração de mecônio permaneceu entre 0,20-0,29 por 1.000 nascidos vivos durante o período do estudo. Conclusões: Apesar da redução nas taxas no Brasil de 2005 a 2010, as taxas de mortalidade neonatal precoce associadas à asfixia perinatal em neonatos no melhor espectro de peso ao nascer e sem malformações congênitas ainda são altas e a síndrome de aspiração de mecônio desempenha um importante papel.

Incidência de eventos adversos cirúrgicos em hospital dia / Incidence of adverse surgical events in hospital day / Incidencia de eventos adversos quirúrgicos en el hospital día

Os eventos adversos cirúrgicos têm especial relevância pelo impacto sobre a saúde dos pacientes e por serem eventos preveníveis. A despeito do crescente número de publicações nessa área, persistem lacunas de conhecimento sobre esses eventos na modalidade da assistência cirúrgica ambulatorial. O objetivo deste trabalho é estimar a incidência de eventos adversos cirúrgicos em um Hospital Dia. Para tanto, o método utilizado foi estudo de coorte histórica, dinâmica de 55.879 pacientes operados em um Hospital Dia entre 2010 e 2014. Os resultados indicam que incidência de eventos adversos cirúrgicos foi de 0,51%. Destes eventos, 0,31% foi de infecções do sítio cirúrgico e 0,19% de outros eventos adversos cirúrgicos distribuídos proporcionalmente em: deiscência da ferida cirúrgica (12,9%), hemorragia (5,2%), flebite (5,2%) e trombose dos membros inferiores (4,9%). Assim, os resultados deste estudo ratificam que a cirurgia realizada em regime ambulatorial de Hospital Dia está relacionada a menores incidências de eventos adversos cirúrgicos quando comparados com outros estudos no mesmo tipo de organização, bem como, com estudos em hospitais convencionais. Esses dados ratificam a segurança da cirurgia ambulatorial, entretanto, é indispensável um sistema de seguimento dos pacientes após alta, no sentido de evitar a subnotificação e sub-registros dos dados, que, na ausência desse, pode ocultar dados e identificar taxas irreais.

Surgical adverse events are particularly relevant because of their impact on patient's health and because they are preventable events. Despite the growing number of publications in this area, there are still gaps of knowledge about these events in the ambulatory surgical care modality. The objective of this work is to estimate the incidence of adverse surgical events in hospital day. The method adopted to that end was a historical, dynamic cohort study of 55,879 patients operated in a hospital day between 2010 and 2014. The results indicate that the incidence of surgical adverse events was 0.51%. Of these, 0.31% were surgical site infections and 0.19% of other surgical adverse events proportionally distributed in surgical wound dehiscence (12.9%), hemorrhage (5.2%), phlebitis (5, 2%) and lower limb thrombosis (4.9%). Thus, the results of this study confirm that the surgery performed in day hospital ambulatory is related to lower incidences of surgical adverse events in comparison to other studies in the same type of organization, as well as to studies in conventional hospitals. These data confirm the safety of ambulatory surgery, however, monitoring patients after discharge is indispensable in order to avoid data underreporting and sub-recording, which, in the absence of such monitoring, can hide data and identify unrealistic rates.

Erratum: Congenital Chikungunya Virus Infection after an Outbreak in Salvador, Bahia, Brazil.

[This corrects the article DOI: 10.1055/s-0036-1587323.].

Congenital Chikungunya Virus Infection after an Outbreak in Salvador, Bahia, Brazil.

There is little information about the congenital chikungunya virus (CHIKV) transmission. We describe two cases of well-documented congenital CHIKV infection in Salvador-Brazil, where CHIKV has been identified since 2014. The outbreak in the city led to the clinical CHIKV diagnoses of both pregnant women 2 days before delivery. Urine and blood samples from the mothers and newborns were collected and tested for reverse transcription-polymerase chain reaction (PCR) analysis for Zika, dengue, and CHIKV. Both neonates and mothers had positive urine and serum PCR results for CHIKV. The newborns had significant perinatal complications and were admitted to the neonatal intensive care unit. The purpose of our case report is to show how severe congenital CHIKV infection can be and the importance to include CHIKV infection in the differential diagnosis of neonatal sepsis when mothers have clinical signs of the disease and live in an affected area.

Risk factors for nosocomial rotavirus infection in a paediatric hospital: the potential role for rotavirus vaccine use.

To analyze the incidence and risk factors (RF) of nosocomial infection (NI) in a paediatric teaching hospital, a retrospective cohort study was conducted in Salvador, Brazil. The Centres for Disease Control and Prevention definitions were used. The detection of the rotavirus antigen in stool was performed using a rapid latex agglutination test. The study group comprised 2978 admissions that accounted for 32,924 patient-days. The incidence of NI was 8.3/1000 patient-days and 9.2/100 admissions. Of the 274 NI episodes, the most common illness and causative agent were gastroenteritis (125; 45.6%) and rotavirus (59; 21.5%), respectively. The RF for rotavirus NI was young age (10+/-8 months vs. 27+/-33 months; mean difference 17 months, 95% CI 15-20 months, p < 0.001). The temporal distribution of community-acquired and NI rotavirus showed similar trends. The universal use of rotavirus vaccine is a potential tool to control NI among children.

Perinatal tuberculosis: a diagnostic challenge

Despite the high prevalence of tuberculosis in adults and children, the congenital and perinatal forms of tuberculosis are rare. In Brazil, there has been only one published case of congenital tuberculosis and two cases of the perinatal form of this disease. We report a case of perinatal tuberculosis presenting with pneumonia. Alcohol-acid-resistant bacilli were found in the gastric lavage. Diagnosis of this disease presentation requires a high index of suspicion.

Estudo da prevalência de hipertensão arterial em mães com recém-nascidos de baixo peso / Study on the prevalence of arterial hypertension in mothers of low birth weight newborns

O objetivo deste trabalho foi estimar a prevalência de hipertensão em mães de recém-nascidos de baixo peso na Maternidade Climério de Oliveira da Universidade Federal da Bahia no período de outubro de 2004 a março de 2005. Métodos: Setenta e sete mulheres com nativivos de peso abaixo de 2.500 g foram entrevistadas - 5,44% de 1.415 partos. Dezenove não preencheram os critérios de inclusão. Recém-nascidos de baixo peso: 44,8% prematuros e 53,4% com restrição de crescimento intra-uterino. Mães: 10,3% sem pré-natal, 36,2% < 5 consultas; 63,8% desfechos desfavoráveis prévios. 1,7% com idade < 17 anos e 6,9% tabagistas. 41,4% primíparas, 6,9%> 4 partos. A prevalência de hipertensão foi de 39,7%, sendo 8,7% hipertensão crônica associada à pré-eclâmpsia; 82,6% com doença hipertensiva específica da gravidez e duas mães com hipertensão crônica. Não houve significância estatística entre o tipo de hipertensão e prematuridade ou restrição de crescimento intra-uterino. A proporção de prematuridade e de restrição de crescimento intra-uterino foi de 52,2% cada, sendo quatro (17,4%) recém-nascidos prematuros e com restrição de crescimento intra-uterino. Quatro (6,9%) das mães não apresentaram nenhum dos fatores de risco para baixo peso analisados neste estudo. A prevalência de hipertensão entre mães com recém-nascidos de baixo peso de 39,7% pode ser considerada importante para realização de políticas de saúde direcionadas, particularmente ao pré-natal. Taxas encontradas também poderão ser úteis para cálculo de número mínimo amostral em trabalhos futuros.

Traumatismos craniencefálicos leves: estudo comparativo entre observação clínica e realização de exames complementares / Minor head injury: comparative study between in-hospital observation and complementary exams

O traumatismo craniencefálico constitui um importante problema de saúde pública nas nações ocidentais e é um dos motivos mais frequentes de procura por assistência médica pós-trauma. A maioria desses traumatismos é leve (escore entre 13 e 15 na Escala de Coma de Glasgow), mas o protocolo de avaliação e tratamento para esse grupo de pacientes permanece controverso. No nosso estudo, foram avaliados 216 pacientes portadores de traumatismo craniano leve, buscando-se comparar a realização de exames complementares (radiografia simples e tomografia computadorizada de crânio) e observação clínica. Os resultados mostraram que a radiografia simples de crânio, apesar de amplamente solicitado, tem valor questionável, enquanto a tomografia computadorizada proporciona sensibilidade diagnóstica bastante superior, sendo muito útil, orincipalmente, se aliada a uma observação clínica cuidadosa.

No evidence of vertical transmission of HTLV-I in bottle-fed children.

The most frequent pathway of vertical transmission of HTLV-I is breast-feeding, however bottle fed children may also become infected in a frequency varying from 4 to 14%. In these children the most probable routes of infection are transplacental or contamination in the birth canal. Forty-one bottle-fed children of HTLV-I seropositive mothers in ages varying from three to 39 months (average age of 11 months) were submitted to nested polymerase chain reaction analysis (pol and tax genes). 81.5% of the children were born by an elective cesarean section. No case of infection was detected. The absence of HTLV-I infection in these cases indicates that transmission by transplacental route may be very infrequent.

No evidence of vertical transmission of HTLV-I in bottle-fed children

The most frequent pathway of vertical transmission of HTLV-I is breast-feeding, however bottle fed children may also become infected in a frequency varying from 4 to 14 percent. In these children the most probable routes of infection are transplacental or contamination in the birth canal.
