Cuidados respiratorios en pacientes con atrofia muscular espinal para evitar el fallo ventilatorio agudo y la traqueostomía: revisión literaria y recomendaciones consensuadas / Respiratory care in patients with spinal muscular atrophy to avoid acute ventilatory failure and tracheostomy: literature review and consensus recommendations

La atrofia muscular espinal (AME) 5q es una de las enfermedades neuromusculares de mayor incidencia en la infancia. Sin embargo, la prevalencia de AME tipo 1, su forma más severa de presentación, es menor debido a muertes prematuras evitables antes de los dos años por insuficiencia ventilatoria subtratada. La irrupción de nuevos tratamientos modificadores de la enfermedad pueden cambiar dramáticamente este pronóstico y es una oportunidad para actualizar el manejo respiratorio, a través de cuidados estandarizados básicos, preferentemente no invasivos, abordando la debilidad de los músculos respiratorios, la insuficiencia tusígena y ventilatoria, con un enfoque preventivo. La siguiente revisión literaria entrega estrategias para evitar la intubación y la traqueostomía usando soporte ventilatorio no invasivo (SVN), reclutamiento de volumen pulmonar (RVP) y facilitación de la tos. Se analizan en detalle los protocolos de extubación en niños con AME tipo 1.

Spinal muscular atrophy (SMA) 5q is one of the neuromuscular diseases with the highest incidence in childhood. Nevertheless, the prevalence of its most severe form SMA1 is lower due to premature preventable deaths before two years of age related to ventilatory insufficiency undertreated. The emergence of new disease-modifying treatments can dramatically change this prognosis and is an opportunity to update respiratory management, through basic standardized care, mostly non-invasive, addressing respiratory muscles pump weakness, cough and ventilatory insufficiency with a preventive approach. This literature review provides consensus recommendations for strategies to avoid intubation and tracheostomy using noninvasive ventilatory support (NVS), lung volume recruitment (LVR), and cough facilitation. Extubation protocols in children with SMA type 1 are analyzed in detail.

Status quo of preterm infants′ feeding difficulties at weaning and self-feeding transition stage and its influencing factors / 中国儿童保健杂志

【Objective】 To investigate the prevalence and influencing factors of feeding difficulties in preterm infants at weaning and self-feeding transition stage, so as to provide a scientific basis for the management of feeding preterm infants. 【Methods】 Preterm infants at corrected age of 6 - 24 months were recruited from the Department of Child Health of five maternal and child health hospital of Chengdu from April to May 2021, and were surveyed by using the Chinese Version of the Montreal Children Hospital Feeding Scale (MCF-FS) and the self-designed questionnaire on the influencing factors of feeding difficulties. Then the status quo of feeding difficulties and its influencing factors were analyzed. 【Results】 The prevalence rate of feeding difficulties in 231 preterm infants was 32%. Among them, the prevalence rate of mild, moderate and severe feeding difficulties was 15.2%, 7.8% and 9.1%, respectively. Binary Logistic stepwise regression analysis indicated that food allergy (OR=4.253, 95%CI: 1.430 - 12.649), anxious mood of caregivers (OR=6.064, 95%CI: 2.998 - 12.268), tease or chase during eating(OR=2.873, 95%CI: 1.382 - 5.970), recreational activities at eating (OR=2.328, 95%CI: 1.115 - 4.860), and forced feeding (OR=2.772, 95%CI: 1.239 - 6.198) were positively associated with feeding difficulty of preterm infants(P<0.05). 【Conclusion】 Feeding difficulties in the weaning and self-feeding transition period of preterm infants are prevalent, so the guidance should focus on premature infants with food allergy, anxious caregivers and improper feeding behaviors, and appropriate interventions should be taken to promote scientific feeding.

Correlation between diaphragmatic-rapid shallow breathing index and lung ultrasound score in elderly patients with mechanical ventilation and its predictive value for weaning results / 中华危重病急救医学

Objective:To investigate the correlation between diaphragmatic-rapid shallow breathing index (D-RSBI) and lung ultrasound score (LUS) in elderly patients with mechanical ventilation and its predictive value for weaning results.Methods:A retrospective study was conducted. The clinical data of elderly patients (age > 60 years old) with invasive positive pressure ventilation (IPPV) admitted to the department of intensive care unit (ICU) of the First Affiliated Hospital of Jinzhou Medical University from January 2021 to June 2022 were enrolled. According to the outcome of withdrawal, the patients were divided into successful and failed groups. The differences in gender, age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), D-RSBI and LUS before weaning and extubation were compared between the two groups. Pearson correlation was used to analyze the correlation between D-RSBI and LUS. The predictive value of D-RSBI and LUS on weaning results of elderly patients with IPPV was analyzed by receiver operator characteristic curve (ROC curve).Results:A total of 398 elderly patients with IPPV were enrolled, including 300 successful weaning patients and 98 failed weaning patients. There were no significant differences in gender and age between the failed group and successful group [male: 55.1% (54/98) vs. 59.0% (177/300), age (years old): 67.02±5.03 vs. 66.96±4.99, both P > 0.05]. APACHEⅡ score in the failed group was significantly higher than that in the successful group (17.09±3.30 vs. 16.06±3.81, P < 0.05), and the D-RSBI and LUS score before extubation were significantly higher than those in the successful group [D-RSBI (time·min -1·mm -1): 2.19±0.33 vs. 1.60±0.22, LUS: 17.30±3.04 vs. 11.97±3.20, both P < 0.01]. All patients showed a significant positive correlation between D-RSBI and LUS score ( r = 0.406, P = 0.000). ROC curve analysis showed that the area under the curve (AUC) of D-RSBI for predicting weaning outcomes in elderly IPPV patients was 0.920, with a 95% confidence interval (95% CI) of 0.881-0.958 and P = 0.000. When the cut-off value was 1.85 times·min -1·mm -1, the sensitivity was 88.7% and the specificity was 86.7%. The AUC of LUS score for predicting weaning outcome in elderly IPPV patients was 0.875, with a 95% CI of 0.839-0.912 and P = 0.000. When the cut-off value was 14.50, the sensitivity was 75.7% and the specificity was 84.7%. Conclusion:There is a significant correlation between D-RSBI and LUS score in elderly mechanically ventilated patients, both of them can predict weaning outcome in elderly patients with mechanical ventilation.

Relação entre desmame precoce e alergias alimentares / Relationship between early weaning and food allergies / Relación entre el destete precoz y las alergias alimentarias

Objetivo: Analisar a relação entre o desmame precoce e o desenvolvimento de alergias alimentares por meio de uma revisão integrativa. Método:Revisão integrativa da literatura realizada através das bases de dados Pubmed, Mesh e Scielo.Resultados:Através da busca pelos descritores determinados, foram selecionados 25 estudos científicos que atenderam aos critérios de inclusão. Devido sua grande composição, o leite humano é responsável pela promoção do crescimento das bactérias com efeito bifidogênico, estando em quantidades superiores nos lactentes em AME. Conclusão: Apesar de alguns dos estudos não mostrarem resultados significativos em relação ao leite materno ser um fator protetor contra as alergias alimentares, nenhum deles deixoude incentivar o AM ou mostrar os seus benefícios já cientificamente comprovados.

Objective: To analyze the relationship between early weaning and the development of food allergies through an integrative review. Method: Integrative literature review performed through the Pubmed, Mesh and Scielo databases. Results: Through the search for the descriptors determined, 25 scientific studies that met the inclusion criteria were selected. Due to its large composition, human milk is responsible for promoting the growth of bacteria with bifidogenic effect, being in higher amounts in infants in EBF. Conclusion: Although some of the studies did not show significant results regarding breast milk being a protective factor against food allergies, none of them failed to encourage BF or show its scientifically proven benefits.

Conclusión:Aunque algunos de los estudios no mostraron resultados significativos con respecto a que la leche materna sea un factor protector contra las alergias alimentarias, ninguno de ellos falló en fomentar la BF o mostrar sus beneficios científicamente probados.

Association of biomarkers with successful ventilatory weaning in COVID-19 patients: an observational study / Associação entre biomarcadores e sucesso do desmame ventilatório em pacientes com COVID-19: um estudo observacional

ABSTRACT Objective: To evaluate the association of biomarkers with successful ventilatory weaning in COVID-19 patients. Methods: An observational, retrospective, and single-center study was conducted between March 2020 and April 2021. C-reactive protein, total lymphocytes, and the neutrophil/lymphocyte ratio were evaluated during attrition and extubation, and the variation in these biomarker values was measured. The primary outcome was successful extubation. ROC curves were drawn to find the best cutoff points for the biomarkers based on sensitivity and specificity. Statistical analysis was performed using logistic regression. Results: Of the 2,377 patients admitted to the intensive care unit, 458 were included in the analysis, 356 in the Successful Weaning Group and 102 in the Failure Group. The cutoff points found from the ROC curves were −62.4% for C-reactive protein, +45.7% for total lymphocytes, and −32.9% for neutrophil/lymphocyte ratio. These points were significantly associated with greater extubation success. In the multivariate analysis, only C-reactive protein variation remained statistically significant (OR 2.6; 95%CI 1.51 - 4.5; p < 0.001). Conclusion: In this study, a decrease in C-reactive protein levels was associated with successful extubation in COVID-19 patients. Total lymphocytes and the neutrophil/lymphocyte ratio did not maintain the association after multivariate analysis. However, a decrease in C-reactive protein levels should not be used as a sole variable to identify COVID-19 patients suitable for weaning; as in our study, the area under the ROC curve demonstrated poor accuracy in discriminating extubation outcomes, with low sensitivity and specificity.

RESUMO Objetivo: Avaliar a associação de biomarcadores com o sucesso do desmame ventilatório em pacientes com COVID-19. Métodos: Trata-se de estudo observacional, retrospectivo e de centro único realizado entre março de 2020 e abril de 2021. Foram avaliados a proteína C-reativa, os linfócitos totais e a relação neutrófilos/linfócitos durante o atrito e a extubação; mediu-se a variação desses valores de biomarcadores. O desfecho primário foi o sucesso da extubação. As curvas ROC foram desenhadas para encontrar os melhores pontos de corte dos biomarcadores segundo a sensibilidade e a especificidade. A análise estatística foi realizada por meio de regressão logística. Resultados: Dos 2.377 pacientes admitidos na unidade de terapia intensiva, 458 foram incluídos na análise, 356 no Grupo Sucesso do desmame e 102 no Grupo Fracasso do desmame. Os pontos de corte encontrados nas curvas ROC foram −62,4% para proteína C-reativa, +45,7% para linfócitos totais e −32,9% para relação neutrófilo/linfócito. Esses pontos foram significativamente associados ao maior sucesso da extubação. Na análise multivariada, apenas a variação da proteína C-reativa permaneceu estatisticamente significativa (RC 2,6; IC95% 1,51 - 4,5; p < 0,001). Conclusão: Neste estudo, uma diminuição nos níveis de proteína C-reativa foi associada ao sucesso da extubação em pacientes com COVID-19. Os linfócitos totais e a relação neutrófilos/linfócitos não mantiveram a associação após a análise multivariada. No entanto, uma diminuição nos níveis de proteína C-reativa não deve ser usada como única variável para identificar pacientes com COVID-19 adequados para o desmame; como em nosso estudo, a área sob a curva ROC demonstrou baixa precisão na discriminação dos resultados de extubação, com baixas sensibilidade e especificidade.

A Simplified Protocol for Tracheostomy Decannulation in Patients Weaned off Prolonged Mechanical Ventilation

Abstract Introduction The criteria for the removal of the tracheostomy tube (decannulation) vary from center to center. Some perform an endoscopic evaluation under anesthesia or computed tomography, which adds to the cost and discomfort. We use a simple two-part protocol to determine the eligibility and carry out the decannulation: part I consists of airway and swallowing assessment through an office-based flexible laryngotracheoscopy, and part II involves a tracheostomy capping trial. Objective The primary objective was to determine the safety and efficacy of the simplified decannulation protocol followed at our center among the patients who were weaned off the mechanical ventilator and exhibited good swallowing function clinically. Methods Of the patients considered for decannulation between November 1st, 2018, and October 31st, 2020, those who had undergone tracheostomy for prolonged mechanical ventilation were included. The efficacy to predict successful decannulation was calculated by the decannulation rate among patients who had been deemed eligible for decannulation in part I of the protocol, and the safety profile was defined by the protocol's ability to correctly predict the chances of risk-free decannulation among those submitted to part II of the protocol. Results Among the 48 patients included (mean age: 46.5 years; male-to-female ratio: 3:1), the efficacy of our protocol in predicting the successful decannulation was of 87.5%, and it was was safe or reliable in 95.45%. Also, in our cohort, the decannulation success and the duration of tracheotomy dependence were significantly affected by the neurological status of the patients. Conclusion The decannulation protocol consisting of office-based flexible laryngotracheoscopy and capping trial of the tracheostomy tube can safely and effectively aid the decannulation process.

Influência da Anquiloglossia neonatal na amamentação exclusiva nos seis primeiros meses de vida: estudo de coorte / Influence of Neonatal Ankyloglossia on exclusive breastfeeding in the six first months of life: a cohort study

RESUMO Objetivo Analisar a influência da anquiloglossia na prevalência e no tempo de exclusividade do aleitamento materno de lactentes a termo até o sexto mês de vida. Métodos Estudo de coorte prospectivo, realizado com 225 díades mãe-bebê que foram acompanhadas nos seis primeiros meses de vida em centro especializado em amamentação em um hospital terciário. Lactentes a termo com anquiloglossia do tipo assintomática (sem necessidade de cirurgia) foram comparados com lactentes sem alteração em um acompanhamento mensal. O diagnóstico de anquiloglossia foi realizado através do Bristol Tongue Assessment Tool, sendo considerados com diagnóstico positivo aqueles com escore menores ou iguais a 5 considerando os aspectos funcionais e anatômicos. As análises estatísticas foram realizadas através de estatística descritiva, regressão logística (determinantes do desmame), risco relativo e curvas de sobrevivência (para analisar o tempo de aleitamento entre os grupos com e sem anquiloglossia). Resultados A anquiloglossia esteve associada com o desmame (considerado ainda que parcial) antes do sexto mês de vida. Após análise ajustada, foi detectado maior risco de desmame nos lactentes com a alteração presente, com risco presente a partir do segundo mês de vida. Na análise de sobrevida, o tempo de aleitamento nos lactentes com anquiloglossia foi menor quando comparadas às crianças sem alteração. Conclusão Em comparação com lactentes com freio lingual normal, os bebês com anquiloglossia apresentaram tempo menor de aleitamento exclusivo, porém bem acima da média observada na população geral. O risco de desmame para este grupo também foi maior.

ABSTRACT Purpose To analyze the influence of ankyloglossia on the prevalence and duration of exclusive breastfeeding of full-term infants up to the sixth month of life. Methods Prospective cohort study, carried out with 225 mother-infant dyads who were followed up in the first six months of life in a center specialized in breastfeeding in a tertiary hospital. Full-term infants with asymptomatic ankyloglossia (no need for surgery) were compared with infants without change at monthly follow-up. Ankyloglossia was diagnosed using the Bristol Tongue Assessment Tool, with a positive diagnosis being considered for those with a score less than or equal to 5 considering functional and anatomical aspects. Statistical analyzes were performed using descriptive statistics, logistic regression (weaning determinants), relative risk, and survival curves (to analyze breastfeeding duration between groups with and without ankyloglossia). Results Ankyloglossia was associated with weaning (considered even partial) before the sixth month of life. After adjusted analysis, a higher risk of weaning was detected in infants with this alteration, with a risk present from the second month of life. In the survival analysis, the duration of breastfeeding in infants with ankyloglossia was shorter when compared to children without alterations. Conclusion Compared to infants with normal lingual frenulum, babies with ankyloglossia had shorter exclusive breastfeeding time, but well above the average observed in the general population. The risk of weaning for this group was also higher.

Prevalence of exclusive breastfeeding up to six months of age in full-term newborns during the pandemic and factors associated with early weaning / Prevalência de aleitamento materno exclusivo até seis meses de vida em bebês nascidos a termo em período da pandemia e fatores associados ao desmame precoce

ABSTRACT Purpose: to investigate the prevalence of exclusive breastfeeding up to 6 months old in full-term newborns at a public hospital and the main factors associated with early weaning, during the pandemic caused by severe acute respiratory syndrome. Methods: an observational, cross-sectional study with 98 mothers of full-term babies, conducted from January to August 2021, during the COVID-19 pandemic. The participants answered two structured questionnaires. One was applied immediately after childbirth, with questions on identification and socioeconomic data, obstetric-gynecological background, and current pregnancy and childbirth. The second questionnaire, applied 6 months after childbirth, had questions about the child's feeding status. Statistical tests were used to associate the prevalence of exclusive breastfeeding up to 6 months old and other variables, at the 5% significance level. Results: 16.3% of the babies were exclusively breastfeeding until the sixth month, during the COVID-19 pandemic, in the public hospital where the study was carried out. Exclusive breastfeeding up to 6 months old was not associated with the study variables. Conclusion: the prevalence of exclusive breastfeeding until the sixth month in full-term babies, in a public hospital, during the COVID-19 pandemic, was 16.3%. None of the variables analyzed was associated with early weaning.

Para verificar a associação entre a prevalência do aleitamento materno exclusivo aos seis meses de vida e as demais variáveis foram aplicados os testes Qui-quadrado, Exato de Fisher, Qui-quadrado de comparações múltiplas e Teste T, com nível de significância de 5%. Resultados: 16,3% dos lactentes encontravam-se em aleitamento materno exclusivo no sexto mês, no período da pandemia da COVID-19, no hospital público onde o estudo foi realizado. Não houve associação entre o aleitamento materno exclusivo aos seis meses de vida e as variáveis pesquisadas. Conclusão: a prevalência de amamentação exclusiva no sexto mês em bebês nascidos a termo em um hospital público, durante a pandemia da COVID-19, foi de 16,3% e nenhuma das variáveis analisadas apresentou associação com o desmame precoce.

Factors associated with the length of breastfeeding during the COVID-19 pandemic: a survival study / Factores asociados a la duración de la lactancia materna durante la pandemia de COVID-19: estudio de supervivencia / Fatores associados à duração do aleitamento materno durante a pandemia da COVID-19: estudo de sobrevida

ABSTRACT Objective: To investigate the repercussions of COVID-19 on the length of breastfeeding and analyze the associated factors in Belo Horizonte, Minas Gerais, Brazil. Method: This is an epidemiological, prospective cohort study. Data were collected from medical records and through telephone interviews. Women who weaned were estimated using Kaplan-Meier survival analysis. The log-rank test was used to verify differences between groups, analyzing weaning time, according to sociodemographic and clinical characteristics. The values of hazard ratio and 95% confidence intervals were estimated using Cox regression analysis. Results: A total of 1,729 women participated in the study. During the COVID-19 pandemic, brown women and women undergoing cesarean section were more likely to stop breastfeeding. Conclusion: The birth route and mothers' ethnic characteristics were associated with early weaning during the COVID-19 pandemic. Such findings are important to guide the assistance of the multidisciplinary team, especially nursing, during the post-pandemic period and in future epidemiological scenarios.

Soluble and insoluble fibre sources in weaning piglets' diets / Fibras solúvel e insolúvel em dietas de leitões na creche

This study evaluated the effect of diets containing low levels of soluble and insoluble fiber sources on performance, diarrhea score, chemical and physical characteristics of feces, and behavior in weaning piglets. Thirty-six weaned piglets of 30 days of age with an initial body weight of 8.8 kg were distributed in 36 pens using a completely randomized design in an experimental period of 21 days. The experimental treatments were the Control diet (CONT), the Control diet + 1% beet pulp inclusion (SBP), and the Control diet + 1% lignocellulose inclusion (LCE, Arbocel®). Feed and water were available ad libitum. Body weight and feed intake were measured weekly to calculate the average daily intake, weight gain, and feed conversion ratio. The fecal consistency was determined visually twice daily, classifying feces according to three scores. To determine fecal pH and concentration of fecal short-chain fatty acids (SCFA), samples of fresh feces were collected two weeks after weaning and measured by a digital pH meter and gas chromatography, respectively. The behavior of piglets was observed once a week, using four animals per treatment, from 14:00 to 16:00, every 12 min. Fibre sources had no effect (P>0.05) on performance, except in the period 15 to 21 days after weaning, which was a tendency (P=0.061) of feed intake decrease in SBP and LCE diets. Fiber sources did not affect the fecal consistency score (P>0.05). However, piglets fed SBP and LCE showed a tendency (P<0.10) to have less diarrhea incidence 15 to 21 days post-weaning and in the entire experimental period. Fecal pH and SCFA concentration were not influenced by fiber source (P>0.05), with acetic, propionic, and butyric acids representing around 71%, 19%, and 10% of the total, respectively. Fiber sources did not influence the social and feeding behavior of weaning piglets (P>0.05). Diets containing 1% fiber sources did not alter performance, diarrhea score, fecal pH, fecal SCFA concentration, or feeding and social behavior of weaned piglets.(AU)

O estudo avaliou o efeito de dietas contendo baixos níveis de fontes de fibra solúvel e insolúvel sobre o desempenho, escore de diarreia, características químicas e físicas das fezes e comportamento de leitões desmamados. Trinta e seis leitões desmamados, com 30 dias de idade e peso vivo inicial de 8,8 kg, foram distribuídos em 36 baias, totalizando 12 repetições por tratamento, em um delineamento inteiramente casualizado. Os tratamentos experimentais foram: dieta controle (CONT), dieta controle + 1% de inclusão de polpa de beterraba (SBP) e dieta controle + 1% de inclusão de lignocelulose (LCE, Arbocel®). A ração e a água foram disponibilizadas ad libitum durante os 21 dias experimentais. O consumo médio diário de ração (CRM), ganho de peso diário (GPD) e a conversão alimentar (CA) foram medidos semanalmente. A consistência fecal foi determinada visualmente duas vezes por dia, classificando as fezes de acordo com três classificações. Amostras frescas de fezes, colhidas no 14° dia experimental, foram usadas para determinação do pH e ácidos graxos de cadeia curta (AGCC). O pH foi medido utilizando pHmetro digital, enquanto os AGCC foram determinados com auxílio de cromatografia gasosa. Para avaliar o comportamento foram observados quatro leitões por tratamento, uma vez por semana, das 14:00 às 16:00, a cada 12 minutos. As fontes de fibra não apresentaram efeito (P>0,05) sobre as variáveis de desempenho, exceto no período de 15 a 21 dias pós desmame, onde se observou uma tendência (P=0,061) de redução no consumo médio nos leitões que receberam as dietas contendo SBP e LCE. Não foi observado efeito das fontes de fibra sobre o escore de consistência fecal (P>0,05), embora leitões alimentados com SBP e LCE apresentaram uma tendência (P<0,10) de redução na incidência de diarreia no período de 15 a 21 dias pós desmame e no período total. O pH e a concentração de AGCC não foram influenciados pelas fontes de fibra (P>0,05), onde entres os tratamentos os perfis dos ácidos acético, propiônico e butírico foram semelhantes 71%, 19% e 10%, respectivamente. Não houve efeito das fontes de fibra sobre os comportamentos social e alimentar dos leitões (P>0,05). Dietas contendo 1% de fontes de fibra não alteram o desempenho, escore de diarreia, pH fecal, concentração de ácidos graxos voláteis nas fezes, bem como o comportamento alimentar e social de leitões desmamados.(AU)

FACTORES PROMOTORES, DIFICULTADES Y ESTRATEGIAS PARA EMPRENDER Y CONTINUAR LA LACTANCIA MATERNA EN ESPAÑA: LA VOZ DE LAS MUJERES / FACTORS THAT PROMOTE, HINDER, AND SUPPORT PROMOTION, HINDERING AND STRATEGIC FACTORS TO BREASTFEEDING IN SPAIN: THE VOICE OF WOMEN

OBJETIVO: Identificar factores promotores, dificultades y estrategias para el inicio y continuación de la lactancia materna (LM), en base a la experiencia de mujeres lactantes. METODOLOGÍA: Estudio cualitativo fenomenológico realizado en la Región de Murcia (España) en el 2019. Se reclutaron a veintisiete mujeres que alimentaron a sus hijos/as con LM en el periodo de 2012-2018 mediante una asociación de LM y un muestreo de bola de nieve. Se realizaron entrevistas personales abiertas y un análisis temático de las transcripciones. RESULTADOS: Se estructuraron en tres temas: 1) Facilidades para el inicio y mantenimiento de la LM, 2) Dificultades ante la LM y 3) Estrategias utilizadas por las mujeres para solventar las barreras. Mientras que la motivación para amamantar y el apoyo recibido facilitaron la LM, las barreras más comunes se relacionaron con miedos e inseguridades personales, cansancio, problemas físicos y la respuesta social frente a la LM. Los motivos de abandono fueron el déficit de producción de leche, la incorporación laboral y la actitud del bebé. Las participantes desarrollaron autocuidados, búsqueda de información y asociaciones de LM y estrategias de conciliación familiar-laboral para paliar las dificultades. CONCLUSIÓN: Es necesaria una mayor implicación por parte de las/os profesionales de la salud para apoyar a las mujeres a través de la herramienta de educación para la salud, el apoyo por pares y medidas institucionales que favorezcan la LM en el lugar de trabajo.

OBJECTIVE: To identify promoting factors, difficulties, and strategies related to the initiation and continuation of breastfeeding (BF), based on the experiences of breastfeeding women. METHODOLOGY: A phenomenological qualitative study conducted in the Region of Murcia (Spain) in 2019. Twenty-seven women who breastfed their children from 2012 to 2018 were recruited through a breastfeeding association and snowball sampling. Personal open interviews were conducted, and a thematic analysis of the transcriptions was performed. RESULTS: The findings were organized into three themes: 1) Facilitators for the initiation and maintenance of BF, 2) Difficulties faced during BF, and 3) Strategies employed by women to overcome the difficulties. While the motivation to breastfeed and provision of support facilitated BF, common challenges were noted, including personal fears and insecurities, fatigue, physical problems, and societal response to BF. Reasons for discontinuation included low milk production, the need to return to work, and the baby's attitude. Participants developed self-care practices, sought information, joined breastfeeding associations, and implemented work-family reconciliation strategies to address the challenges. CONCLUSION: Greater involvement from healthcare professionals is necessary to support women who breastfeed through health education, peer support, and institutional measures that promote BF in the workplace.

Relationship between handgrip strength and inspiratory muscles with the success of the spontaneous breathing trial

Introduction: In critically ill patients on mechanical ventilation, the loss of inspiratory and peripheral muscle strength is associated with prolonged mechanical ventilation and failed weaning. Objective: To determine the relationship between handgrip strength and inspiratory muscle strength with the success of the Spontaneous Breathing Trial in adults with ventilatory support greater than 48 hours. Methodology: Prospective observational cross-sectional study performed at a tertiary hospital in Colombia. Handgrip strength and Maximal Inspiratory Pressure were measured once a day before Spontaneous Breathing Trial testing. Pearson's test and Cohen's D test were used to analyze correlations. Results: A total of 51 patients were included, 57% male, with a mean age of 51.9±20 years. A positive correlation was identified between Maximal Inspiratory Pressure and grip strength; and a negative correlation between grip strength and Maximal Inspiratory Pressure with the days of stay in the intensive care unit, (r -0.40; p<0.05) and (r -0.45; p<0.05). Conclusions: Handgrip strength and Maximal Inspiratory Pressure were positively correlated with Spontaneous Breathing Trial success. The importance of these measures to guide ventilator disconnection processes is highlighted.

Introducción: En el paciente críticamente enfermo con ventilación mecánica, la pérdida de la fuerza de los músculos inspiratorios y periféricos se asocia con ventilación mecánica prolongada y destete fallido. Objetivo: Determinar la relación entre la fuerza de prensión manual y la fuerza de músculos inspiratorios con el éxito de la prueba de respiración espontánea en adultos con soporte ventilatorio mayor a 48 horas. Metodología: Estudio prospectivo observacional de corte transversal realizado en un hospital de tercer nivel en Colombia. La fuerza de prensión manual y la presión inspiratoria máxima se midieron una vez al día antes de la prueba de prueba de respiración espontánea. Se utilizaron la prueba de Pearson y la prueba D de Cohen para analizar las correlaciones. Resultados: Se incluyeron 51 pacientes, 57 % de sexo masculino, con una edad promedio de 51,9 ± 20 años. Se identificó una correlación positiva entre Presión Inspiratoria Máxima y fuerza de la mano; y una correlación negativa entre la fuerza de la mano y la Presión Inspiratoria Máxima con los días de estancia en la Unidad de Cuidados Intensivos, (r -0,40; p < 0,05) y (r -0,45;p < 0,05). Conclusiones: La fuerza de prensión manual y la Presión Inspiratoria Máxima se correlacionaron positivamente con el éxito de la Prueba de Respiración Espontánea. Se destaca la importancia de estas mediciones para guiar procesos de desconexión del ventilador.

Physicochemical and Nutritional Properties of Baby-Led Cookies Produced from Rice, Banana and Cashew-nut Flour Blends

Aim: Cookies from rice, banana and cashew-nut flour blends were prepared as alternative to gluten-free baby-led food for children. Place and Duration of Study: The study was carried out in the Chemistry Laboratory, Department of Science Laboratory Technology, University of Medical Sciences, Ondo, Nigeria and Food Processing Laboratory, Department of Food Technology, Auchi Polytechnic, Auchi, Nigeria between August, 2022 and January, 2023. Methodology: Baby-led weaning cookies were formulated from flour blends as 100% raw rice (RRC), 50% rice and 50% wheat (RWC) and 40% rice, 20% cashew and 40% unripe banana (RCB) and their physical properties, sensory attributes, proximate properties, mineral compositions, vitamin profiles and anti-nutrients were determined and compared with 100% commercial cookie (CMC) with the view to substituting wheat flour with suitable flour blends with enhanced nutritional quality. Results: The peak diameter (10.40±0.20 mm), thickness (6.37±0.06 mm) and weight (17.65±0.04 g) were obtained in RCB. Spread ratio was highest (2.66±0.11) and lowest (1.42±0.01) in CMC and RWC respectively while spread factor decreased from 100% in CMC to 77.19% (RRC), 53.46% (RWC) and 62.47% (RWC). The grittiness, texture, aroma, taste and general acceptability of RCB were significantly similar to those of CMC (P < 0.05). Na, K, Mg and Zn contents increased in RCB. Proximate compositions (%) of the cookies formulated varied significantly from CMC. Peak crude protein (14.49±0.59), crude fibre (4.03±0.02) and fat (32.22±0.00) in RCB, ash (3.28±0.02) and carbohydrate by difference (58.15±0.13) in CMC and moisture (18.19±0.11) in RRC. The peak values of fat-soluble vitamins (A, D, E, K) and water-soluble vitamins (B1, B2, B3, B6, B9, B12, C) were most abundant in RCB. The proportions (mg/g) of phytate, oxalate, tannins and phenols in the cookies formulated were comparatively lower than the lethal dose, implying that the cookies would be safe for consumption. Conclusion: RCB cookie had excellent nutritional quality, which, as a novel baby-led weaning cookie, could serve as a suitable alternative to commercial cookies.

Resumen Introducción: Alrededor del 50% de los pacientes hos pitalizados por injuria cerebral adquirida grave requie ren traqueostomía y cuidados a largo plazo. El objetivo principal de este estudio fue describir la evolución de enfermos con injuria cerebral adquirida grave (ICAg) traqueostomizados que ingresaron a rehabilitación. Se cundariamente se estudió el fracaso de la decanulación y la supervivencia a los 12 meses del alta. Métodos: estudio cuantitativo observacional prospec tivo de centro único. Se incorporó al estudio, de forma prospectiva y consecutiva, usuarios mayores de 18 años, traqueostomizados posterior a ICAg ingresados a un cen tro de rehabilitación entre abril de 2018 y marzo de 2020. Resultados: se incluyeron para el análisis 50 pacien tes. La estancia en el centro fue de 203 (RIQ 93-320) días. Al alta de la institución, 32 (64%) pacientes pudieron ser decanulados exitosamente. El tiempo transcurrido desde el ingreso al centro hasta la decanulación fue de 49 (12-172) días. No se observó fracaso de la decanula ción. La mortalidad a los 12 meses de seguimiento fue de 32%, cinco (16%) de los 32 pacientes que pudieron ser decanulados y 11 (61%) de los 18 que no lograron la decanulación fallecieron dentro de los 12 meses de seguimiento. La relación entre la decanulación y la mortalidad a los 12 meses de seguimiento resultó esta dísticamente significativa (p = 0.002). Discusión: La supervivencia global fue relativamente elevada, el proceso de decanulación resulta relevante ya que puede tener impacto en la supervivencia a largo plazo.

Abstract Introduction: About 50% of patients hospitalized for severe acquired brain injury require tracheostomy, and many of them need long-term care. The main objective of this study was to describe the evolution of patients with severe acquired brain injury (sABI) tracheotomized who entered rehabilitation. Secondarily, mortality re lated to the success or failure of decannulation and survival at 12 months of discharge were studied. Methods: A single-center prospective observational quantitative study. Users over 18 years of age were recruited prospectively and consecutively, tracheosto mized after sABI, and admitted to a rehabilitation center between April 2018 and March 2020. Results: Fifty patients were included for analysis. The stay in the center was 203 (RIQ 93-320) days. At discharge to the institution, 32 (64%) patients managed to be successfully decannulated. The median number of days from admission to the center to decannulation was 49 (12-172). No decannulation failure was observed. Mortality at 12 months follow-up was 32%, five (16%) of the 32 patients who managed to be decannulated, and 11 (61%) of 18 who failed to achieve decannulation died within 12 months of follow-up. The relationship between decannulation success and mortality at 12 months of follow-up was statistically significant (p= 0.002). Discussion: Addressing the decannulation process early and properly guided is relevant as it may impact long-term survival.

Crisis Miasténica: Reporte de Caso y Revisión de la Literatura / Myasthenic Crisis: Case Report and Literature Review

Introducción. La crisis miasténica es la complicación más grave que sufren los pacientes con Miastenia Gravis. Esta enfermedad se caracteriza clínicamente por debilidad muscular generalizada, que particularmente mejora con el reposo y empeora con el ejercicio debido al agotamiento de la conducción nerviosa a nivel post sináptico. El manejo de la crisis miasténica tiene como piedra angular tratar la causa desencadenante, así como utilizar los fármacos de acción rápida y los descritos en la literatura para enfrentar este escenario, como la plasmaféresis, inmunoglobulinas o terapia biológica. Además, es crucial tener un adecuado manejo desde el punto de vista ventilatorio manteniendo la protección pulmonar y sobre todo diafragmática, con las herramientas disponibles en la actualidad al lado de la cama del paciente. Asimismo, el weaning o destete del ventilador mecánico debe llevarse a cabo de manera objetiva y bajo evaluaciones específicas para lograr un desenlace optimo.

Introduction. Myasthenic crisis is the most serious complication suffered by patients with Myasthenia Gravis. This disease is clinically characterized by generalized muscle weakness, which particularly improves with rest and worsens with exercise due to depletion of nerve conduction at the post-synaptic level. The cornerstone of managing myasthenic crisis is treating the triggering cause, as well as using fast-acting drugs and interventions described in the literature to deal with this scenario, such as plasmapheresis, immunoglobulins, or biological therapy. In addition, it is imperative to ensure adecuate management from the ventilatory perspective, preserving lung function and safeguarding the diaphragm with the tools currently available at the patient's bedside. Likewise, weaning from the mechanical ventilator must be conducted objectively and guided by specific evaluations to achieve an optimal outcome.

Conocimientos de madres y padres sobre lactancia materna exclusiva / Knowledge level of parents on exclusive breast feeding i:en

Introducción: La leche materna es considerada la vacuna perfecta de todos los tiempos y la mejor fuente de nutrición para los niños. Objetivo: Determinar el nivel de conocimientos de madres y padres sobre lactancia materna exclusiva. Métodos: Se realizó un estudio descriptivo y transversal de 27 madres y 27 padres de lactantes con destete precoz, pertenecientes al área de salud del Policlínico Docente Camilo Torres Restrepo de Santiago de Cuba, desde enero hasta diciembre del 2021, para lo cual el instrumento empleado fue la encuesta. Resultados: Se halló que los conocimientos sobre lactancia materna fueron considerados altos en 13 madres (48,1 %) y medios en 11 padres (40,7 %). Todos los integrantes de la serie recibieron información sobre el tema y las vías fundamentales para ello fueron los medios de difusión masiva (85,0 %), seguidos de los familiares y amigos (55,0 %). Conclusiones: El conocimiento acerca de la lactancia materna exclusiva en los padres resultó insuficiente y, en las madres, fue necesario ampliar dichos conocimientos sobre las técnicas para amamantar.

Oxigenoterapia de alto flujo y ventilación no invasiva en pacientes extubados por COVID-19 y riesgo de reintubación / High-flow oxygen therapy and non-invasive ventilation in extubated patients with COVID-19 and risk of reintubation

RESUMEN Introducción: La oxigenoterapia de alto flujo (OAF) y la ventilación no invasiva (VNI) son sistemas no invasivos que se administran post-extubación en pacientes COVID-19 para evitar la reintubación. Sin embargo, la evidencia sobre la elección de alguno de estos dispositivos no está muy clara. El objetivo fue determinar si el grupo que recibió OAF comparado con el grupo que recibió VNI se asocia a menor riesgo de reintubación en adultos con destete difícil y extubados por COVID-19. Material y métodos: Estudio cohorte retrospectivo en 206 registros de pacientes en destete difícil de ventilación mecánica en la Unidad de Cuidados Intensivos (UCI). El resultado primario fue reintubación en pacientes que fracasaron con OAF o VNI post-extubación y los resultados secundarios fueron estancia hospitalaria en UCI y mortalidad a los 90 días. Resultados: Doscientos seis pacientes cumplieron los criterios de inclusión, 102 pacientes en el grupo OAF y 104 pacientes en el grupo VNI. Durante el seguimiento de 72 horas, la tasa de reintubación en el grupo OAF fue mayor [n=24 (64,9%)] comparado con el grupo VNI [n=13 (35,1%)], mostrando en el análisis de Kaplan-Meier diferencias significativas (Log-Rank-Test p=0,005). La regresión de COX mostró mayor riesgo de reintubación en el grupo de OAF frente a VNI (HR 2,74; IC95% 1,42-5,68; p=0,007). No hubo diferencias en los días de hospitalización UCI (p=0,913) ni en mortalidad a los 90 días (Log-Rank-Test p=0,49). Conclusión: Este estudio observacional retrospectivo sugirió que la OAF frente al VNI se asoció a mayor riesgo de reintubación, pero no a mortalidad a los 90 días.

ABSTRACT Introduction: High flow oxygen therapy (HFO) and non-invasive ventilation (NIV) are non-invasive systems that are administered post-extubation in COVID-19 patients to avoid reintubation. However, the evidence on the choice of any of these devices is not very clear. The objective was to determine if the group that received OAF compared to the group that received NIV is associated with a lower risk of reintubation in adults with difficult weaning and extubated due to COVID-19. Material and methods: Retrospective cohort study in 206 records of patients in difficult weaning from mechanical ventilation in the Intensive Care Unit (ICU). The primary outcome was reintubation in patients who failed HFO or post-extubation NIV, and the secondary outcomes were ICU hospital stay and 90-day mortality. Results: Two hundred and six patients met the inclusion criteria, 102 patients in the OAF group and 104 patients in the NIV group. During the 72-h follow-up, the reintubation rate in the HFO group was higher [n=24 (64,9%)] compared to the NIV group [n=13 (35,1%)], showing in the analysis of Kaplan-Meier significant differences (Log-Rank-Test p=0,005). COX regression showed a higher risk of reintubation in the HFO group compared to NIV (HR 2,74; 95%CI 1,42-5,68; p=0,007). There were no differences in ICU hospitalization days (p=0,913) or in 90-day mortality (Log-Rank-Test p=0,49). Conclusion: This retrospective observational study suggested that HFO versus NIV was associated with a higher risk of reintubation, but not with 90-day mortality.

Multiparameters Associated to Successful Weaning from VA ECMO in Adult Patients with Cardiogenic Shock or Cardiac Arrest: Systematic Review and Meta?Analysis

Venoarterial extracorporeal membrane oxygenation (VA ECMO) is a form of temporary mechanical circulatory support and simultaneous extracorporeal gas exchange for acute cardiorespiratory failure, including refractory cardiogenic shock (CS) and cardiac arrest (CA). Few studies have assessed predictors of successful weaning (SW) from VA ECMO. This systematic review and meta-analysis aimed to identify a multiparameter strategy associated with SW from VA ECMO. PubMed and the Cochrane Library and the International Clinical Trials Registry Platform were searched. Studies reporting adult patients with CS or CA treated with VA ECMO published from the year 2000 onwards were included. Primary outcomes were hemodynamic, laboratory, and echocardiography parameters associated with a VA ECMO SW. A total of 11 studies (n=653) were included in this review. Pooled VA ECMO SW was 45% (95%CI: 39�%, I2 7%) and in?hospital mortality rate was 46.6% (95%CI: 33�%; I2 36%). In the SW group, pulse pressure [MD 12.7 (95%CI: 7.3�) I2 = 0%] and mean blood pressure [MD 20.15 (95%CI: 13.8�.4 I2 = 0) were higher. They also had lower values of creatinine [MD �59 (95%CI: �9 to �2) I2 = 7%], lactate [MD �1 (95%CI: �4 to �7) I2 = 89%], and creatine kinase [�79.5 (95%CI: �87 to �1) I2 = 38%]. And higher left and right ventricular ejection fraction, MD 17.9% (95%CI: �2�.2) I2 = 91%, and MD 15.9% (95%CI 11.9�) I2 = 0%, respectively. Different hemodynamic, laboratory, and echocardiographic parameters were associated with successful device removal. This systematic review demonstrated the relationship of multiparametric assessment on VA ECMO SW.

Experiência do processo de desmame materno entre primíparas: estudo qualitativo / Experience of the maternal weaning process among primiparous women: qualitative study / Experiencia del proceso de destete materno entre las primíparas: estudio cualitativo

RESUMO Objetivo: compreender a experiência do processo de desmame para as mães primíparas de um município do interior do Ceará, Brasil. Método: estudo descritivo e qualitativo, realizado com oito mulheres, mediante entrevistas semiestruturadas. Coleta de dados de agosto de 2022 a março de 2023, na Atenção Primária à Saúde, adotando-se a análise de conteúdo de Bardin. Resultados: emergiram três categorias temáticas: motivos para a mãe decidir sobre o desmame; estratégias empregadas pela mãe para realizar o desmame; e consequências do desmame para a mãe e a criança. As percepções maternas sobre a motivação do desmame relacionaram aspectos comportamentais da criança e necessidades maternas. Variadas estratégias foram classificadas em desmame gradual ou abrupto, que geraram mudanças no comportamento das crianças e sentimentos contraditórios nas mães. Considerações finais: o desmame é vivenciado de forma desagradável, gerando sofrimento. Desvela-se a desassistência por profissionais e a necessidade de ampliação de estudos.

ABSTRACT Objective: To understand the experience of the weaning process for primiparous mothers in a municipality in the interior of Ceará, Brazil. Method: Using semi-structured interviews, a descriptive, qualitative study was conducted with eight women. Data collection from August 2022 to March 2023 in Primary Health Care, using Bardin's content analysis. Results: three thematic categories emerged: reasons for the mother's decision to wean, strategies employed by the mother to wean, and the consequences of weaning for the mother and child. Maternal perceptions of the motivation for weaning were related to behavioral aspects of the child and maternal needs. Various strategies were classified as gradual or abrupt weaning, which generated changes in the children's behavior and contradictory feelings in the mothers. Final considerations: weaning is experienced unpleasantly, generating suffering. It reveals the lack of professional assistance and the need to expand studies.

Prevalência de aleitamento materno exclusivo e fatores associados em um município do extremo sul catarinense / Prevalence of exclusive breastfeeding and associated factors in a city of southern of Santa Catarina State, Brazil

Identificar a prevalência de aleitamento materno exclusivo e fatores relacionados durante os seis primeiros meses de vida do lactente. Trata-se de um estudo transversal realizado com 102 nutrizes residentes no município de Balneário Gaivota(SC) que efetivaram o pré-natal na rede pública ou privada e tiveram parto no ano de 2018. Os dados foram coletados por aplicação de questionário contemplando as variáveis sociodemográficas, gestacionais e pós-gestacionais. A prevalência de aleitamento materno exclusivo foi de 43,1%. Aqueles bebês que usavam mamadeira tiveram 45% menos probabilidade de ter recebido aleitamento materno exclusivo até os 6 meses de idade, e aqueles que receberam prescrição de fórmula infantil na alta hospitalar apresentaram 54% menos chance comparados aos seus pares. Os fatores relacionados ao aleitamento materno exclusivo são comportamentais e modificáveis, sendo necessária a orientação pelos profissionais de saúde durante a consulta pré-natal, puericultura e no acompanhamento do desenvolvimento infantil.

To identify the prevalence of exclusive breastfeeding and its related factors during the first six months of the infant's life. This is a cross-sectional study carried out with 102 nursing mothers residing in the city of Balneário Gaivota( SC) who performed prenatal care in the public or private network and gave birth in 2018. Data were collected by application of a questionnaire and included sociodemographic, gestational and post-gestational variables. The prevalence of exclusive breastfeeding was 43.1%. Those babies who used a bottle were 45% less likely to have been exclusively breastfed up to six months of age, and those who were prescribed infant formula at hospital discharge were 54% less likely compared to their peers. Factors related to exclusive breastfeeding are behavioral and modifiable, thus, guidance by health professionals is necessary during prenatal and childcare consultations and in the monitoring of child development.
