Enteral nutrition and refeeding syndrome in a patient with anorexia nervosa and COVID-19

Introduction: the evidence on the health problem-related prevalence of COVID-19 is an emergency. Case report: we present the case of a 28-year-old woman who had had a behavioral eating disorder (BED) since age 12. Her body mass index (BMI) was 13.6 kg/m2. She was hospitalized for a respiratory condition (bronchospasm) due to COVID-19, with supplementary oxygen at two liters. During her stay, she refused food and was started on standard enteral nutrition via a naso-gastric tube. She developed refeeding syndrome (RFS), which was managed with electrolytes, and her enteral diet was changed to a low-carbohydrate high-protein diet. She received psychological therapy through video calls, recovered, and was discharged to home. Discussion: refeeding complications increase when a high caloric rate is begun. The standard enteral formula has 54% carbohydrates, which contributes to the risk of developing RFS. The consequences of BED and COVID-19 are unknown, and it is likely to become more evident over time. (Acta Med Colomb 2022; 48. DOI:https://doi.org/10.36104/amc.2023.2626).

Impact of Industrial Practices on the Microbial and Quality Attributes of Fresh Vacuum-Packed Lamb Joints.

The impact of different industrial practices at lamb export abattoirs in Ireland on the microbial and quality attributes of fresh vacuum-packed (VP) lamb leg joints, including Clean Livestock Policy (CLP), fleece clipping, carcass chilling times and vacuum pack storage, at typical chill and retail display temperatures was investigated. Five separate slaughter batches of lamb (ranging in size from 38 to 60 lambs) were followed at two lamb export plants over a two-year period, accounting for seasonal variation. In general, fleece clipping resulted in significantly lower microbial contamination on the fleece than the use of CLP alone. Lamb from carcasses chilled for 24 h had significantly lower psychrophilic total viable counts and Brochothrix thermosphacta and pseudomonad counts than carcasses chilled for 72 h. Following vacuum-packed (VP) storage of meat from these carcasses at 1.7 ± 1.6 °C for 23 days in the meat plant followed by retail display at 3.9 ± 1.7 °C (up to day 50), the dominant microorganisms were lactic acid bacteria, Br. thermosphacta, Enterobacteriaceae and pseudomonads, and all had reached maximum population density by storage day 34. Aligned with this, after day 34, the quality of the raw meat samples also continued to deteriorate, with off-odours and colour changes developing. While the mean values for cooked meat eating quality attributes did not change significantly over the VP storage period, high variability in many attributes, including off-flavours and off-odours, were noted for lamb meat from all storage times, highlighting inconsistences in lamb quality within and between slaughter batches.

Principles and recent applications of novel non-thermal processing technologies for the fish industry-a review.

Thermal treatment is a traditional method for food processing, which can kill microorganisms but also lead to physicochemical and sensory quality damage, especially to temperature-sensitive foods. Nowadays consumers' increasing interest in microbial safety products with premium appearance, flavor, great nutritional value and extended shelf-life has promoted the development of emerging non-thermal food processing technologies as alternative or substitution to traditional thermal methods. Fish is an important and world-favored food but has a short shelf-life due to its extremely perishable characteristic, and the microbial spoilage and oxidative process happen rapidly just from the moment of capture, making it dependent heavily on post-harvest preservation. The applications of novel non-thermal food processing technologies, including high pressure processing (HPP), ultrasound (US), pulsed electric fields (PEF), pulsed light (PL), cold plasma (CP) and ozone can extend the shelf-life by microbial inactivation and also keep good sensory quality attributes of fish, which is of high interest for the fish industry. This review presents the principles, developments of emerging non-thermal food processing technologies, and also their applications in fish industry, with the main focus on microbial inactivation and sensory quality. The promising results showed great potential to keep microbial safety while maintaining organoleptic attributes of fish products. What's more, the strengths and weaknesses of these technologies are also discussed. The combination of different food processing technologies or with advanced packaging methods can improve antimicrobial efficacy while not significantly affect other quality properties under optimized treatment.

[Tetanus, a current disease in pediatric population: Case report]. / Tétanos, una enfermedad vigente en población pediátrica: Reporte de un caso.

INTRODUCTION: Tetanus is an acute disease caused by a toxin produced by Clostridium tetanii. The disease can affect people of any age, and the fatality rate is high. Thanks to immunization the number of cases of the disease has decreased, although they are still present in isolation in countries with social and economic backwardness. OBJECTIVE: To describe a case of a pediatric patient with generalized tetanus to reinforce the relevance of prophylaxis and early detection. CASE REPORT: 6 years old female patient, with only one dose of pentavalent vaccine, 10 days after sharps injury by wood chips, starts with fever, muscle pain and generalized contractions, Tetanus was diagnosed by clinical symptoms and history. The management was based on the latest recommendations of the World Health Organization (WHO): Penicillin-Metronidazole antibiotic regimen, tetanus toxoid and tetanus high-dose gammaglobulin. After 2 years of follow-up under physiotherapy support, slight motor sequelae were observed. CONCLUSION: Tetanus is still presented in the pediatric population, associated with lack of vaccination. It is necessary to know the disease to provide proper diagnosis and management according to international lineaments.

Tétanos, una enfermedad vigente en población pediátrica: Reporte de un caso / Tetanus, a current disease in pediatric population: Case report

Introducción: El tétanos es una enfermedad aguda causada por una toxina producida por Clostridium tetanii. La enfermedad puede afectar a personas de cualquier edad, y la tasa de letalidad es alta. Gracias a la inmunización se ha logrado reducir el número de casos de la enfermedad, aunque se siguen presentando casos sobre todo en países con rezago social y económico. Objetivo: Describir caso clínico de un paciente pediátrico con tétanos generalizado, para reforzar la importancia de la profilaxis y diagnóstico precoz. Caso clínico: Escolar femenina de 6 años de edad con antecedente de esquema de inmunizaciones incompleto (una dosis de pentavalente), quien 10 días después de hacerse una herida cortopunzante por astilla de madera en brazo derecho, evolucionó con fiebre, dolor muscular y contracciones generalizadas, diagnosticándose tétanos generalizado en base a los antecedentes y el cuadro clínico. El tratamiento se estableció en base a las últimas recomendaciones de la Organización Mundial de la salud (OMS): esquema antibiótico Penicilina-Metronidazol, toxoide tetánico y gammaglobulina antitetánica a dosis altas. Se da de alta con secuelas motoras leves, las que se remitieron luego de 2 años de seguimiento y terapia de rehabilitación. Conclusión: El tétanos se sigue presentando en la población pediátrica principalmente asociado a falta de vacunación, es necesario conocer la enfermedad para hacer diagnóstico temprano y ofrecer manejo acorde a recomendaciones internacionales.

Combined treatments of high-pressure with the lactoperoxidase system or lactoferrin on the inactivation of Listeria monocytogenes, Salmonella Enteritidis and Escherichia coli O157:H7 in beef carpaccio.

The effect of high hydrostatic pressure (HHP) treatments in combination with the lactoperoxidase system (LPOS) or activated lactoferrin (ALF) on Listeria monocytogenes, Salmonella enterica subsp. enterica serovar Enteritidis and Escherichia coli O157:H7 was investigated in cured beef carpaccio stored at 8 °C or 22 °C during 7 d. HHP (450 MPa for 5 min) reduced pathogen levels by 1-3 log units and the antimicrobial effect remained during 7 d of storage under temperature abuse conditions at 8 °C and at 22 °C. The individual application of LPOS and ALF did not affect the survival of the three pathogens studied during storage. However, a synergistic bactericidal interaction between LPOS and HHP was observed against S. Enteritidis and E. coli O157:H7. Combined treatments of HHP with LPOS would be useful to reduce the intensity of pressurization treatments diminishing changes in the quality of meat products.

High pressure treatments on the inactivation of Salmonella Enteritidis and the characteristics of beef carpaccio.

The effect of high pressure (HP) on Salmonella enterica subsp. enterica serovar Enteritidis in beef carpaccio stored under temperature abuse conditions (8 °C) during 30 days was investigated. After treatment, reductions of S. Enteritidis were 3.68 and 5.94 log cfu/g in samples pressurized at 450 MPa for 5 and 10 min, respectively, whereas the pathogen was only detected after enrichment of samples treated at 450 MPa for 15 min. During storage, counts of S. Enteritidis decreased 0.26 log cfu/g in non-pressurized carpaccio, 1.33 log cfu/g in carpaccio treated at 450 MPa for 5 min and were only detected after enrichment in carpaccio pressurized at 450 MPa for 10 or 15 min. Color (L*, a* and b*) varied with pressurization and storage, with higher changes in carpaccio treated at longer pressurization times. Shear resistance was slightly lower in treated samples just after pressurization, but increased at the end of the storage period. Maximum force was less affected by treatment.

High pressure treatments on the inactivation of Salmonella Enteritidis and the physicochemical, rheological and color characteristics of sliced vacuum-packaged dry-cured ham.

The effect of high pressure (HP) on Salmonella Enteritidis in sliced dry-cured ham stored under temperature abuse (8°C) during 60d was investigated. After treatment, reductions of S. Enteritidis were 1.06, 2.54 and 4.32 log units in ham treated at 400, 500 and 600MPa for 5min at 12°C, compared to non-pressurized samples. After 60d, counts of S. Enteritidis in ham treated at 400 and 500MPa were 2.56 and 2.66 log units lower than in non-treated ham, whereas the pathogen was only detected after enrichment in ham treated at 600MPa. Lipid oxidation increased with storage and pressurization, whereas total free amino acid contents were similar in HP and control samples after 60d. Dry-cured ham treated at the highest pressures exhibited lower shear resistance, whereas the maximum force to compress the sample was slightly changed. Color (L*, a* and b*) varied with pressurization and storage. Changes induced by HP in dry-cured ham were attenuated during storage.

Niveles de andrógenos, estilos parentales y conducta agresiva en niños y niñas de 5-6 años de edad / Androgen levels, parenting styles and aggressive behavior in 5-6-year-old boys and girls

El presente estudio explora la relación entre los niveles de andrógenos, el estilo educativo parental y medidas de agresión física, verbal e indirecta en niños y niñas de 5-6 años. 129 niños (60 chicos y 69 chicas) fueron evaluados respecto a sus niveles de agresión a través de una técnica de estimación por pares. Los padres cumplimentaron el Parenting Styles Dimensions Questionnaire, a partir del cual se obtuvieron los estilos educativos parentales. Los niveles de testosterona, androstenediona y dehidroepiandrosterona (DHEA) fueron evaluados utilizando una técnica de enzimoinmunoensayo en muestras de saliva. Un análisis de regresión indicó que la interacción madre directiva-androstenediona a los 5 años fue predictiva de la agresión física a los 6 años. De forma específica, se observó que en los chicos con altos niveles de androstenediona, la conducta maternal directiva se asoció con la agresión física. Se discuten los resultados a la luz de planteamientos relacionados con la educación y la crianza característicos de la psicología del desarrollo, y se sugiere una posible relación de los resultados con la hipótesis de la dominancia maternal (AU)

This study explores the relationship between androgen levels, parenting styles, and physical, verbal, and indirect aggression measures in 5-6-year-old children. 129 children (60 boys and 69 girls) were assessed in relation to their aggression levels using a peer-rating technique. Parents completed the Parenting Styles and Dimensions Questionnaire, from which the different parenting styles were obtained. Testosterone, androstenedione and dehydroepiandrosterone (DHEA) were measured using an enzymoimmunoassay technique in saliva samples. A regression analysis indicated that the directive mother-androstenedione interaction at the age of 5 was predictive of physical aggression at the age of 6. In specific terms, the results showed that, in boys with high androstenedione levels, directive maternal behavior is associated with physical aggression. The results are subsequently discussed in light of postulates related to parenting characteristic of developmental psychology and we suggest a potential link of our results with the hypothesis of maternal dominance (AU)

Aproximación al estudio de las actitudes y estrategias de pensamiento social y su relación con los comportamientos disruptivos en el aula en la educación secundaria / An approach to the study of attitudes and strategies of social thought and their connection with disruptive behavior in the secondary school classroom

Una de las principales preocupaciones del profesorado de secundaria son las, cada vez más frecuentes, relaciones conflictivas que mantienen con algunos alumnos y que dificultan el normal desarrollo de las clases. El presente estudio persigue analizar qué componentes de la competencia social se relacionan con la presencia de comportamientos disruptivos en una muestra de 348 alumnos de un centro de secundaria. En el primer ciclo de ESO, los chicos disruptivos obtuvieron puntuaciones más altas en liderazgo prosocial, en agresividad y terquedad, y en impulsividad; las chicas de este ciclo obtuvieron puntuaciones más bajas en sensibilidad social. En el segundo ciclo de ESO, entre los chicos no se detectaron diferencias estadísticamente significativas entre los sujetos disruptivos y los no disruptivos; entre las chicas, las calificadas como disruptivas obtuvieron puntuaciones más bajas en ayuda y colaboración y conformidad con lo que es socialmente correcto, y más altas en independencia frente a dependencia de campo. Pensamos que el diseño de estrategias de intervención orientadas a la modificación de los componentes más directamente relacionados con la conflictividad escolar necesitan tener en cuenta los perfiles diferenciales de chicos y chicas, disruptivos y no disruptivos (AU)

Colpocitología y gestación / Colpocytology and pregnancy

En este estudio prospectivo a 460 mujeres gestantes asistentes al programa de control prenatal se les practicó colpocitología con el propósito de identificar infecciones cervicovaginales, neoplasia intraepitelial cervica (NIC) y factores de riesgo para cáncer cervicouterino. En 301 mujeres (65.4 por ciento) se diagnosticó proceso infeccioso por patógenos diversos; 3 casos por clamida, 4 por papiloma virus y dos pacientes con NIC grados I y II. En 40 pacientes (8.6 por ciento) se identificaron más de dos factores de riesgo para desarrollar lesiones precursoras o cáncer de cérvix. El conocimiento de la prevalencia de NIC e infección cervico vaginal en la gestación, debe ser tomado en consideración para la prevención del producto, la pareja y el riesgo potencial de la mujer para desarrollar cáncer cervicouterino
