Incidence of hypopituitarism in adults undergoing radiotherapy for neck and head cancer: protocol for a systematic review and meta-analysis.

INTRODUCTION: When children with head and neck cancer receive radiation therapy as part of their treatment, a considerable frequency of hypopituitarism has been recognised. However, in adults, it has been little studied and it is possible that patients may be inadvertently affected. The objective is to estimate the incidence of anterior pituitary dysfunction in adults undergoing radiotherapy for head and neck cancer. METHODS AND ANALYSIS: A total of five databases will be used to perform the document search: PubMed, Scopus, Web of Science (Core Collection), Ovid-MEDLINE and Embase. Cohort studies will be included without restriction by language or date. The main outcome will be the incidence of adenohypophyseal dysfunction for each axis: prolactin, growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, luteinising hormone and follicle-stimulating hormone. Incidence meta-analysis will be performed using the Freeman-Tukey double arcsine method. In addition, a random-effects model will be used along with a 95% CI. Subgroup analyses will be performed according to tumour location, radiation dose and endocrine assessment time. Meta-regression will be applied according to patient's age and time elapsed until diagnosis. ETHICS AND DISCLOSURE: Since this will be a systematic review of published data, no ethics committee approval is required. The results will be presented at conferences and finally published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42021235163.

Nutritional support in the critical ill patient: Requirements, prescription and adherence.

INTRODUCTION: In critically ill patients, nutritional support is a challenge in terms of both estimating their requirements and ensuring adherence to the prescribed treatment. OBJECTIVE: To assess the association between requirements, prescription and adherence to energy and protein supplementation based on the phase of disease in critically ill patients. SAMPLE AND METHODS: We conducted a prospective, observational and analytical study in patients aged 0-18 years admitted to the paediatric intensive or intermediate care unit in 2020-2021. We collected data on demographic and anthropometric characteristics and the phase of disease (acute phase [AP] vs. non-acute phase [nAP]), in addition to prescribing (P) (indication of nutritional support), basal metabolic rate (BMR, Schofield equation), adherence to nutritional support (A) and protein requirements (R), and calculated the following ratios: P/BMR, P/R, A/BMR, A/R, and A/P. RESULTS: The sample included 131 participants with a median age of 16 (4.5) months, of who 128 (97.7%) had comorbidities and 13 (9.9%) were in the AP. Comparing the phases of disease (AP vs. nAP), the median values for energy supplementation were P/BMR, 0.5 (IQR, 0.1-1.4) vs. 1.3 (IQR, 0.9-1.8) (P = 0.0054); A/BMR, 0.4 (IQR, 0-0.6) vs. 1.2 (IQR, 0.8-1.7) (P = 0.0005); A/P, 0.7 (IQR, 0-0.9) vs. 1 (IQR, 0.8-1) (P = 0.002), and for protein were P/R, 0.7 (IQR, 0-1.1) vs. 1.2 (0.9-1.6) (P = 0.0009); A/R 0.3 (IQR, 0-0.6) vs. 1.1 (IQR, 0.8-1.5) (P = 0.0002); A/P 0.7 (IQR, 0-1) vs. 1(IQR, 0.8-1) (P = 0.002). We found AP/nAP ratios greater than 110% for energy in the P/BMR (4 patients [30.8%]/72 patients [61%]; P = 0.007), A/BMR (3 [23%]/63 [53.4%]; P = 0.009) and A/P (1 [7%]/3 [2.5%]; P = 0.007). As for protein, more than 1.5 g/kg/day was prescribed in 3 patients (23.1%) in the AP and 71 (60.1%) in the nAP. We found adherence to the prescribed intake in 2 (15.4%) patients in the AP and 66 (56%) in the nAP. We found a correlation coefficient of 0.6 between the energy P/R and the protein P/R. Prescribed support was discontinued in 7 patients (53.8%) in the AP and 31 (26.3%) in the nAP (P = 0.002). CONCLUSIONS: The proportion of adherence to prescribed nutritional support was high in patients in the nAP of the disease. Overfeeding was frequent, more so in the nAP. We identified difficulties in adhering to prescribed support, chief of which was the discontinuation of feeding.

Soporte nutricional en el paciente crítico: requerimiento, prescripción y cumplimiento / Nutritional support in the critical ill patient: Requirements, prescription and adherence

Introducción: El soporte nutricional en el paciente crítico es un desafío tanto en la estimación de requerimientos como en el cumplimiento de su prescripción. Objetivo: Evaluar las relaciones entre la prescripción, el requerimiento y el cumplimiento del soporte nutricional de energía y proteínas según la fase de la enfermedad en el paciente crítico. Pacientes y método: Estudio observacional, analítico, de datos obtenidos a través de reclutamiento prospectivo (2020-2021), pacientes de 0-18 años hospitalizados en la unidad de cuidados intensivos o intermedios pediátrica. Se obtuvieron datos demográficos, antropométricos y del estado agudo (FA)/no agudo (FNA) de la enfermedad. Se determinaron la prescripción (P) (indicación nutricional), el gasto energético basal (GEB) (fórmula de Schofield), el cumplimiento (C) de soporte nutricional, el requerimiento (R) proteico, creándose las siguientes relaciones: P/GEB, P/R, C/GEB, C/R, C/P.

Uso de fuentes de información en estudiantes de Medicina de una universidad de Tacna, Perú

El uso de fuentes de información es importante en la formación del estudiante de medicina; sin embargo, en Latinoamérica se ha reportado una disminución en su empleo y se han identificado problemas en su conocimiento. El objetivo del estudio consistió en determinar los factores asociados al uso de las fuentes de información en estudiantes de Medicina de una universidad de Tacna, Perú. Se realizó un estudio observacional, analítico y transversal en estudiantes de una universidad privada, mediante un muestreo aleatorio estratificado. Se utilizó un instrumento autoaplicado de forma virtual, que indagó en las características socioeducativas, la frecuencia de uso/capacitación de las fuentes de información y las características de la investigación científica. El resultado del estudio indicó un mayor uso de las fuentes de información, asociado con las variables independientes, mediante los modelos de regresión múltiple. De 274 estudiantes, el 32,1 % utilizó frecuentemente las fuentes de información. Las de mayor uso fueron: Google Académico (36,5 %) y SciELO (25,2 %); en contraste, la mayoría de los estudiantes desconocen las fuentes: HINARI (56,2 %) y EMBASE (55,5 %). Desempeñarse en un año académico superior y tener más percepción de las habilidades en la búsqueda de información científica, constituyen los factores asociados a un mayor uso de las fuentes de información.

The use of information sources is important in the training of the medical student; however, in Latin America a decrease in its use has been reported and problems have been identified in its knowledge. The objective of the study was to determine the factors associated with the use of information sources in medical students at a university in Tacna, Peru. An observational, analytical and cross-sectional study was carried out in students of a private university, using a stratified random sampling. A virtual self-applied instrument was used, which inquired into the socio-educational characteristics, the frequency of use/training of the information sources and the characteristics of scientific research. The result of the study indicated greater use of information sources, associated with the independent variables, through multiple regression models. Out of 274 students, 32.1% frequently used information sources. The most used were: Google Scholar (36.5%) and SciELO (25.2%); in contrast, most students are unaware of the sources: HINARI (56.2%) and EMBASE (55.5%). In conclusion, performing in a higher academic year and having more perception of the skills in the search for scientific information are the factors associated with greater use of information sources.

Invasive fungal infection by Saprochaete capitata in a child with bone marrow aplasia. / Infección fúngica invasiva por Saprochaete capitata en un niño con aplasia medular.

Saprochaete capitata is a rare cause of invasive fungal infection in immunocompromised patients with high mortality and antifungal resistance. We present the case of a 5-year-old boy with bone marrow aplasia, who underwent hematopoietic stem cell transplantation (HSCT) and presented persistent febrile neutropenia, abdominal pain, appearance of maculopapular lesions on the skin, and impaired renal function. The presence of S. capitata was identified by blood culture from a central venous catheter. This invasive fungal infection is rare but emergent and life-threatening, especially in immunocompromised patients with persistent febrile neutropenia and prolonged use of invasive devices such as central venous catheters.

Saprochaete capitata es una causa rara de infección fúngica invasiva en pacientes inmunocomprometidos con alta mortalidad y resistencia antifúngica. Presentamos el caso de un niño de cinco años con diagnóstico de aplasia medular, sometido a trasplante de progenitores hematopoyéticos (TPH), que cursó con neutropenia febril persistente, dolor abdominal intenso, aparición de lesiones maculopapulares en piel y deterioro de la función renal. Se identificó la presencia de S. capitata, en hemocultivos transcatéter venoso central. Esta infección fúngica invasiva resulta ser rara, pero emergente y potencialmente mortal, en pacientes con neutropenia febril persistente y uso prolongado de dispositivos invasivos intravasculares como catéter venoso central.

Beneficios del rol de enfermería en salud escolar, implementación a nivel internacional. Revisión sistemática / Benefits of the nursing role in school health, implementation at international level. Systematic review

La salud escolar en Chile se desarrolla a nivel de la Atención Primaria en salud a cargo de los profesionales de enfermería, quienes por su rol deben velar por el bienestar integral de la comunidad escolar, fortaleciendo conductas de autocuidado y hábitos saludables a través de la promoción y prevención e investigación en salud. OBJETIVO: Analizar los beneficios del rol de enfermería en salud escolar desde el punto de vista político y social en países en que ha sido legalmente implementada a nivel internacional. MÉTODOS: Se realizó una revisión sistemática de la literatura científica en bases de datos (Scielo, Pubmed, Scopus, Sciencedirect, Oxford, Web of Science). Se utilizó el flujograma PRISMA. La calidad metodológica consideró los criterios de alto, medio y bajo cumplimiento de 46 indicadores de una pauta de lectura crítica. RESULTADOS: Se identificaron 32 artículos en los últimos 5 años. Las líneas temáticas encontradas fueron las políticas públicas en salud escolar, destacando países como EEUU, España y México con regulación sobre la Enfermera escolar, en cambio en Latinoamérica, existe una regulación parcial o carencia como en Chile. Las competencias y acciones del profesional de enfermería en establecimientos educacionales tienen como prioridad la promoción de la salud y la educación a la comunidad escolar. Se evidencia que las consultas que atiende la enfermera escolar son de urgencia y son variables según la zona geográfica. CONCLUSIONES: La implementación legal del rol de enfermería escolar ofrece ventajas significativas para la mejora del sistema sanitario del país, incrementando la calidad asistencial y mejorando el acceso a salud.

Chilean school health is developed at the level of Primary Health Care in charge of nursing professionals, who for their role must ensure the comprehensive well-being of the school community, strengthening self-care behaviors and healthy habits through promotion and prevention and health research. OBJECTIVE: To analyze the benefits of the nursing role in school health from the political and social point of view in countries where it has been legally implemented internationally. METHODS: A systematic review of the scientific literature in databases (Scielo, Pubmed, Scopus, Sciencedirect, Oxford, Web of Science) was carried out. The PRISMA flow chart was used. The methodological quality considered the criteria of high, medium and low compliance with 46 indicators of a critical reading pattern. RESULTS: 32 articles were identified in the last 5 years. The thematic lines found were public policies in school health, highlighting countries such as the US, Spain and Mexico with regulations on school nurses, on the other hand in Latin America, there is a partial regulation or lack as in Chile. The competences and actions of the nursing professional in educational establishments have as a priority the promotion of health and education to the school community. It is evident that the consultations attended by the school nurse are urgent and vary according to the geographical area. CONCLUSIONS: The legal implementation of the role of school nursing offers significant advantages for the improvement of the country's health system, increasing the quality of care and improving access to health.

Quiloperitoneo en diálisis peritoneal: reporte de caso y revisión sistemática de la literatura / Chyloperitoneum in peritoneal dialysis: a case report and review of literature

El quiloperitoneo es una condición infrecuente que se asocia a diálisis peritoneal; en la mayoría de los casos se puede confundir con peritonitis bacteriana, aunque puede ser la consecuencia de esta infección. Se reporta el desarrollo espontáneo de quiloperitoneo en un paciente de 54 años con enfermedad renal crónica secundaria a nefropatía diabética, en diálisis peritoneal manual desde hacía 5 años. El tratamiento consistió en suspensión temporal de la diálisis peritoneal, reposo intestinal, suministro de una dieta con alto contenido de ácidos grasos de cadena media e infusión de octreotide, con lo cual a los 10 días el paciente mostró mejoría, y se reinició la diálisis peritoneal. Una búsqueda sistemática de la literatura encontró 16 casos publicados (11 mujeres), con edades desde neonato hasta 88 años.

Chyloperitoneum is a rare condition associated with peritoneal dialysis. In most cases it is misdiagnosed as bacterial peritonitis, but it can also be a consequence of this infection. We present the spontaneous development of chyloperitoneum in a 54 year old patient with chronic kidney disease secondary to diabetic nephropathy, in manual peritoneal dialysis for 5 years. The treatment consisted of temporary suspension of peritoneal dialysis, bowel rest, supply of a diet with a high content of medium chain fatty acids and infusion of octreotide. After 10 days the patient showed improvement, and peritoneal dialysis was restarted. A systematic search of the literature found 16 published cases (11 women), ranging in age from newborn to 88 years.

Toxicity of star fruit (Averrhoa carambola) in renal patients: A systematic review of the literature.

Several reports have discussed the neurotoxic effects of star fruit (Averrhoa carambola) in patients with chronic kidney disease (CKD). There is also some evidence highlighting the potentially harmful effects on patients with apparently normal renal function, who after consuming this fruit, developed acute renal injury. We performed a systematic review of the literature in the two main global databases (PubMed and Embase) as well as in Lilacs, for Latin American publications. We also included case reports, case series, or review articles which presented individual patient data. Animal or in vitro studies were excluded. We initially screened 259 references, of which 42 were selected for full-text review and 26 were finally selected for data extraction. A total of 123 patients from eight countries were documented: Brazil, with 47 cases, had the highest reported incidence, followed by Taiwan (36), Bangladesh (20), China and France (8 each), Sri Lanka (2), and Thailand and Colombia (1 each); 28 (22%) of the patients died. Despite the relatively low frequency of star fruit consumption, it has become a global issue. Patients with already diagnosed CKD are the obvious target for preventive measures, but persons with undiagnosed kidney conditions could also be at risk.

[Intradiaphragmatic bronchopulmonary sequestration: a case report and review]. / Secuestro broncopulmonar intradiafragmático: reporte de caso y revisión de la literatura.

Bronchopulmonary sequestration is a rare congenital malformation, consisting in a mass of nonfunctioning lung tissue with no connection to the tracheobronchial tree. It can be classified into intra- and extra-lobar. Extra-lobar bronchopulmonary sequestration accounts for 25% of them; of these, only 1% are intra-diaphragmatic. There is little international literature about intra-diaphragmatic bronchopulmonary sequestration and its diagnosis and treatment remain a challenge for the surgeon. Our case is a newborn with antenatal diagnosis of an abdominal mass by ultrasound and magnetic resonance imaging (MRI) showing a left adrenal tumor that appeared to be a neuroblastoma. Postnatal computed tomography (CT) revealed the likelihood of an intra-diaphragmatic bronchopulmonary sequestration, although neuroblastoma could not be ruled out. Abdominal laparoscopy was performed in the bulging left hemidiaphragmatic area. A combined thoracoscopic approach was decided which showed that the defect was located in between both cavities. This is the first case of intra-diaphragmatic bronchopulmonary sequestration reported in Chile.

El secuestro broncopulmonar es una malformación congénita rara, consistente en una masa de tejido pulmonar no funcionante sin conexión al árbol traqueobronquial. Esta puede clasificarse en intra y extralobar. El extralobar corresponde al 25% de los secuestros broncopulmonares y sólo el 1% es intradiafragmático. Existe escasa literatura internacional sobre secuestro broncopulmonar intradiafragmático, por lo que su diagnóstico y tratamiento es un desafío para el cirujano. Nuestro caso es un recién nacido con diagnóstico antenatal de una masa abdominal por ecografía y resonancia magnética nuclear, las cuales mostraron un tumor adrenal que impresiona ser un neuroblastoma. Se realizó tomografía axial computarizada postnatal donde el secuestro broncopulmonar intradiafragmático apareció como más probable. No se pudo excluir el neuroblastoma. Se realizó laparoscopía abdominal en la que se observó un bulto en el hemidiafragma izquierdo. Se decidió un abordaje toracoscópico combinado, el cual mostró que el defecto se encontraba entre ambas cavidades. Este es el primer caso reportado de secuestro broncopulmonar intradiafragmático en Chile.
