Self-reported clinical features and treatment effectiveness of Papillon-Lefèvre syndrome patients from five Latin American countries: A cross-sectional online survey study.

BACKGROUND/OBJECTIVES: Most studies about Papillon-Lefèvre syndrome (PLS) are limited to case reports and patients of the same nationality. This study aimed to determine the self-reported prevalence of signs, symptoms and treatment effectiveness in PLS patients from five Latin American countries. METHODS: An online survey was conducted among adult and paediatric patients from Mexico, Argentina, Colombia and Brazil. Data were collected using multiple-choice, open-ended and image-chooser questions on demographics, signs and symptoms, perceived treatment effectiveness and quality of life. RESULTS: Seventeen patients (10 males and 7 females) aged 4-47 years were surveyed. All had palmoplantar hyperkeratosis. Other affected sites were the feet and hand dorsum (82.35%), Achilles tendon (88.24%), forearms (58.82%), legs (29.41%) and glutes (23.53%). They frequently presented hyperhidrosis and nail pitting. Four had a history of delayed umbilical cord separation. All used topical treatments, with moderate effectiveness; half used oral retinoids, perceived as highly effective. Most reported decreased quality of life and walking difficulties. CONCLUSIONS: The study's results align with prior research on PLS, but reveal new insights, including the impact on patients' quality of life and a history of delayed umbilical cord separation. These findings warrant consideration in future research and patient care.

Over the Counter Products for Acne Treatment and Maintenance in Latin America: A Review of Current Clinical Practice.

BACKGROUND: The prevalence and clinical presentation of acne vulgaris in Latin America are comparable to that in Europe and the United States. This review aims at insight into the role of Over the Counter (OTC) products in acne treatment and maintenance in Latin America. METHODS: A panel of dermatologists from Latin America employed an online procedure to answer questions on this topic: What is used, by whom, when, how, and why? Before the meeting, a survey was completed by dermatologists from Latin America on OTC products for acne recommended by the panel in their clinical practice. The survey information and a literature review on Latin American acne guidelines and clinical studies were used to address this topic. RESULTS: The survey responders' choices on OTC products for monotherapy comprised alpha-hydroxy acid and beta-hydroxy acid-containing serum, ceramides-containing foaming cleanser, a soap-free exfoliating cleanser, adapalene, and benzoyl peroxide-containing products. The clinicians recommended OTC cleansing products mainly for younger patients at a starter level and for women with adult acne. The use of these OTC products is similar to practice described in therapeutic acne guidelines and algorithms for Latin American countries, Spain and Portugal, Europe, and the United States. CONCLUSIONS: Advisors agreed that OTC products and skincare recommendations, in addition to the use of prescription medications, are a crucial part of successful acne therapy. Participants noted that the use of quality OTC products could improve acne symptomatology and severity.

Consumption of non-nutritive sweeteners by pre-schoolers of the food and environment Chilean cohort (FECHIC) before the implementation of the Chilean food labelling and advertising law.

BACKGROUND: Consumption of non-nutritive sweeteners (NNS) is becoming increasingly more frequent, particularly in the context of obesity prevention policies. The aim of this study was to describe the consumption of NNS in an ongoing cohort of pre-schoolers (4-6-year-old) before the implementation of the Chilean Food Labelling and Advertising Law, identify sociodemographic and anthropometric characteristics associated with their consumption, and describe the main dietary sources of each NNS sub-type. METHODS: In 959 low-medium income pre-schoolers from the Food and Environment Chilean Cohort (FECHIC), dietary data from a single 24-h recall was linked to NNS content information obtained from packaged foods (n = 12,233). The prevalence of NNS consumption was estimated by food source and characterized by child and maternal sociodemographic and anthropometric variables. Intakes and main dietary sources were described for the six most prevalent NNS in Chile: Sodium Cyclamate, Saccharin, Aspartame, Acesulfame Potassium, Sucralose, and Steviol glycosides. RESULTS: Sixty-eight percent of the pre-schoolers consumed at least one source of NNS on the day of the dietary recall; most of them consumed NNS from foods and beverages (n = 532), while only 12% (n = 119) also consumed table-top sweeteners. The prevalence of NNS consumption was significantly higher among children whose mothers had a high educational level compared to children whose mothers did not complete high school (p < 0.05); however, it did not differ by any other variable studied. The highest intakes of NNS were observed for Aspartame [2.5 (1.4-3.7) mg/kg per consumer], followed by Sodium Cyclamate [1.6 (1.3-2.6) mg/kg per consumer] and Steviol glycosides [1.2 (0.2-2.1) mg/kg per consumer]. Beverages were the only food group that contributed to the intake of the six NNS studied, accounting for 22% of the overall intake of Saccharine and up to 99% of Aspartame intake. CONCLUSIONS: Before the implementation of the Food Labelling and Advertising Law, NNS consumption was highly prevalent among a cohort of low-middle income Chilean pre-schoolers. Continuous monitoring of NNS consumption is essential given potential food reformulation associated with the implementation of this set of obesity-prevention policies.

Monitoring modifiable risk factors for breast cancer: an obligation for health professionals.

SYNOPSIS Worldwide, breast cancer is the most common disease in women and constitutes the second leading cause of cancer death in this population. The factors that contribute to the risk of occurrence are divided into nonmodifiable and modifiable factors. Although there are interventions in primary care to prevent the disease, these measures have not produced the desired changes in women's health. This article reviews the major modifiable risk factors for breast cancer and describes how these factors can affect the incidence of cancer in women. This information shows that modifiable risk factors (such as physical activity, diet, obesity, and use of alcohol and tobacco) can influence the occurrence of breast cancer, in part depending on the life stage of a woman, including menopausal status. Timely prevention at the primary care level is one of the most important areas on which health professionals need to focus in order to help reduce the incidence of breast cancer.

[Assessment of a nutrition education intervention among construction workers]. / Evaluación de una intervención educativa nutricional en trabajadores de la construcción para prevenir enfermedades crónicas no transmisibles en Chile.

BACKGROUND: Unhealthy lifestyles and overweight are common among blue collar workers. AIM: To evaluate a nutrition education intervention in construction workers to prevent chronic diseases. MATERIAL AND METHODS: One hundred forty two participants were randomly assigned to an experimental group (n = 69) and or a control group (n = 73). The experimental group received nutrition education consisting in individual lifestyle counseling, group workshop, group counseling in healthy lifestyles, and environmental intervention. At baseline and after one year of intervention, clinical evaluations consisting in laboratory determinations, anthropometry and nutritional assessment evaluation were carried out. RESULTS: The experimental group experienced a significant decrease in waist circumference, total cholesterol, triglycerides, and an increase in HDL cholesterol. A significant reduction in total calorie intake, especially at the evening snack was observed during week-days. The same reduction in total calories occurred at dinner during the week-end. A significant increase was observed in the consumption of fruits, vegetables and fish. In the control group there was a significant increase in weight, waist circumference, body mass index, glucose and insulin, without changes in total calorie intake or healthy food consumption. High soft drink consumption did not change in both groups. CONCLUSIONS: In construction workers, integral nutrition intervention at the individual, group and environmental level had an impact in nutritional and biochemical indicators.

[Feeding habits and lifestyles of male construction workers]. / Estilos de vida, alimentación y estado nutricional en trabajadores de la construcción de la Región Metropolitana de Chile.

BACKGROUND: The less affluent and educated members of the society tend to be less prone to healthy lifestyles. AIM: To describe feeding habits, nutrition, quality of life and working conditions of construction workers comparing two recent surveys, namely the 2009 Chilean National Health Survey (NHS) and the 2010 Work, Employment and Health Survey (WEH). MATERIAL AND METHODS: One hundred ninety male workers aged 43±13 years were surveyed about feeding habits during working days and weekends, smoking and usual physical activity. Weight, height and blood pressure were also measured. RESULTS: In 2010, 82% of workers were overweight or obese compared with 67% rates in the NHS of 2009. The rate of sedentariness was 86% compared with 84% in the NHS of 2009 and 93% in the WEH 2010. Forty one percent smoked and those aged less than 25 years consumed more calories than the other age groups. There was a high intake of carbonated beverages, bread, salted and red meats and a low consumption of fruits, vegetables, legumes and fish. Seventy seven percent had a meal at midafternoon and only 25% ate supper. Lunch had a fixed schedule, was considered good and usually was prepared by a family member. The level of satisfaction with work, family life and life in general was high. The satisfaction with health and physical condition was lower. CONCLUSIONS: The unhealthy lifestyles of these construction workers should alert health authorities.

Understanding the life experience of people on hemodialysis: adherence to treatment and quality of life.

This hermeneutic-phenomenological study explores the lived experiences of patients on hemodialysis in regard to the adherence to treatment and quality of life. Fifteen patients were interviewed, including six women and nine men from three dialysis centers in Chile. Two main themes derived from the analysis: 1) embracing the disease and dialysis, and 2) preventing progression of the disease through treatment management. The findings suggest that patients recognize adherence to treatment and quality of life as conditions that derive from self-care and environmental conditions, which the healthcare provider must constantly assess for care planning to improve the adherence and quality of life in this population.

Cross-species transmission and PB2 mammalian adaptations of highly pathogenic avian influenza A/H5N1 viruses in Chile.

H5N1 highly pathogenic avian influenza viruses (HPAIV) emerged in wild birds in Chile in December 2022 and spilled over into poultry, marine mammals, and one human. Between December 9, 2022 - March 14, 2023, a coordinated government/academic response detected HPAIV by real-time RT-PCR in 8.5% (412/4735) of samples from 23 avian and 3 mammal orders. Whole-genome sequences obtained from 77 birds and 8 marine mammals revealed that all Chilean H5N1 viruses belong to lineage 2.3.4.4b and cluster monophyletically with viruses from Peru, indicating a single introduction from North America into Peru/Chile. Mammalian adaptations were identified in the PB2 segment: D701N in two sea lions, one human, and one shorebird, and Q591K in the human and one sea lion. Minor variant analysis revealed that D701N was present in 52.9 - 70.9% of sequence reads, indicating the presence of both genotypes within hosts. Further surveillance of spillover events is warranted to assess the emergence and potential onward transmission of mammalian adapted H5N1 HPAIV in South America.

Sweetness of Chilean Infants' Diets: Methodology and Description.

Sugars and other sweeteners contribute to the sweet taste of foods; exposure to this taste could alter appetite regulation and preferences for sweet products. Despite this, there is no widely accepted methodology for estimating overall diet sweetness. The objective of this study was to develop a methodology to estimate diet sweetness and describe diet sweetness in a cohort of Chilean infants. In order to estimate diet sweetness density, the sweetness intensity of foods was obtained from existing databases and from sensory evaluations in products with no available information and then linked to 24-h dietary recalls of infants at 12 and 36 months of age. Diet sweetness density was significantly and positively associated with total sugars and non-nutritive sweeteners intakes. The main food sources of sweetness at 12 months were fruits (27%) and beverages (19%). Sweetness density increased 40% between 12 and 36 months (from 1196 to 1673, p < 0.01), and sweetness density at both ages was significantly associated. At 36 months, beverages and dairy products were the main sources of sweetness (representing 32.2% and 28.6%, respectively). The methodology presented here to estimate the sweetness density of the diet could be useful for other studies to help elucidate different effects of exposure to high sweetness.

FINAL CONSIDERATIONS: Caring with cultural relevance is a challenge for nursing, training in cultural competence is required and continue researching on the subject.

[Impact of a teachers' program on food habits and culinary skills in Chilean public schools]. / Efecto de un programa para profesores sobre cambio de hábitos alimentarios y habilidades culinarias en escuelas públicas de Chile.

INTRODUCTION: Objective: to evaluate a healthy food program for teachers and their educational transfer through an action plan for 3rd to 5th primary students, to improve their food habits and culinary skills. Methodology: a four months quasi-experimental prospective study was carried out, with qualitative measurements to teachers (n = 43) and pre- and post-intervention quantitative measurements for students (n = 302) in three public schools compared with a control group in other three schools (n = 265) in La Reina county, Santiago, Chile. The teachers received on-line training and at the end of the program they designed an action plan to be implemented at the three intervened schools. Results: half of the students reported that they had dinner at night. A high percentage had breakfast and lunch twice a day. At the end of the study, the number of students who had lunch twice a day was reduced to a half. Also, the group significantly increased the water and fruits consumption, instead of snacks. In culinary skills, they learned how to prepare healthy sandwiches. As a result, the level of obesity in both groups decreased significantly. The teachers increased water consumption, limited the number of meals to three per day, and decreased the fast food eating. Conclusion: the healthy food training improved the food habits of teachers and students. The support of the headmaster and the staff of the school is required to organize activities to promote healthy food.

INTRODUCCIÓN: Objetivo: evaluar un programa de alimentación saludable para docentes y su transferencia educativa a través de un plan de acción a alumnos de 3º a 5º básico para mejorar sus hábitos alimentarios y habilidades culinarias. Metodología: estudio cuasi-experimental prospectivo de cuatro meses de duración, con mediciones cualitativas a profesores (n = 43) y cuantitativas pre- y postintervención en alumnos (n = 302) de tres colegios municipales, comparados con un grupo control de otros tres colegios (n = 265) en la comuna de La Reina, Santiago de Chile. Los profesores recibieron una capacitación on-line y al final del curso elaboraron un plan de acción que aplicaron en los colegios intervenidos. Resultados: en hábitos y consumo alimentarios, la mitad de los niños refirió que cenaba en la noche y un alto porcentaje desayunaba y almorzaba dos veces. Los que almorzaban dos veces disminuyeron a la mitad al final de la intervención. En el grupo intervenido aumentó significativamente la fruta como colación y en ambos grupos, la ingesta de agua. En habilidades culinarias, el grupo intervenido mejoró la preparación de sándwich. En ambos grupos disminuyó significativamente la obesidad. En los profesores mejoraron el consumo de agua y el hábito de comer tres veces al día y disminuyó la ingesta de comida rápida. Conclusión: la capacitación en alimentación saludable para profesores mejora sus hábitos alimentarios, los cuales se transfieren a sus alumnos. Para ello se debe contar con el apoyo de la dirección de la escuela y con equipos docentes interesados en organizar actividades de promoción de alimentación saludable.

Gusto dulce: Percepción, fuentes alimentarias y preferencias

El dulzor es un atributo característico de alimentos y bebidas que contienen azúcares u otros edulcorantes. El uso de azú-cares ha sido reemplazado por otros edulcorantes, a fin de disminuir los efectos nocivos de éstos en diferentes resultados de salud. Sin embargo, se ha sugerido que el gusto dulce, independiente de su origen, podría tener efectos indeseados en la salud. En este artículo se revisan diversos aspectos relacionados con el gusto dulce, desde su percepción, su presencia en alimentos y líquidos, las preferencias innatas y adquiridas por este gusto y los productos que lo aportan. Se analiza además la importancia de estudiar el rol del gusto dulce en la dieta y salud.

Sweetness is a characteristic of foods and beverages that contain sugars or other sweeteners. Sugars have been replaced by other sweeteners to reduce their harmful effects on different health outcomes. However, it has been suggested that the sweet taste, regardless of its origin, could have unwanted effects on health. This article reviews various aspects of sweet taste, from its perception, presence in foods and liquids, innate and acquired preferences for this taste, and the products that provide it. We also analyzed the importance of studying the role of sweet taste in diet and health.

Chemical and sensory assessment of extra virgin olive oil blends with omega-3 polyunsaturated fatty acids from plant origin

Extra virgin olive oil (EVOO) is known for its health benefits, although it provides a minimum amount of n-3 polyunsaturated fatty acids (n-3 PUFA), which play an important role in the human organism. In this study, EVOO was blended with vegetable oils which are rich sources of n-3 PUFA alpha-linolenic acid (ALA) and/or stearidonic acid (SDA) (chia, walnut, linseed and viper's bugloss seed oils). Fatty acid profiles, induction time, and organoleptic characteristics of the resulting blends were assessed. The n-3 PUFA enrichment in the blends was proportional to the degree of blending. Sensory analysis carried out by a trained panel showed that it is possible to enrich EVOO with up to 20% chia, linseed and viper's bugloss seed oil without altering the original organoleptic characteristics of EVOO. However, the induction time of the blends was significantly reduced compared with EVOO even after adding n-3 PUFA in small proportions, meaning that shelf-life time of these blends is much lower than that of EVOO, which should be considered when preparing these products for commercial purposes.

El aceite de oliva extra virgen (AOEV) es ampliamente conocido por sus beneficios para la salud, aunque apenas aporta ácidos grasos poliinsaturados n-3 (AGPI n-3), los cuales juegan un papel importante en el organismo humano. En este estudio se elaboraron mezclas de AOEV con aceites vegetales ricos en ácido alfa-linolénico (ALA) y/o estearidónico (SDA) (chia, nuez, linaza y viborera). Se evaluaron los perfiles de ácidos grasos, tiempos de inducción y características organolépticas de las mezclas resultantes. El enriquecimiento en AGPI n-3 fue proporcional al grado de mezcla. El análisis sensorial llevado a cabo por un panel entrenado mostró que es posible enriquecer AOEV con hasta un 20% de aceite de chia, linaza o viborera sin alterar las características organolépticas originales del AOEV. Sin embargo, los tiempos de inducción de las mezclas fueron significativamente menores que el del AOEV, incluso tras añadir AGPI n-3 en pequeñas proporciones, lo que significa que el tiempo de vida media de las mezclas es mucho menor que el del AOEV. Este hecho debería tenerse en cuenta al preparar las mezclas con propósitos comerciales.

Teachers' self-perception of their dietary behavior and needs to teach healthy eating habits in the school.

Through focus groups, we explored 22 third- to fifth-grade teachers' perceptions about their eating habits, including barriers and facilitators to healthy eating. It also explored teachers' thoughts about how to teach students healthy eating habits. The information was transcribed and treated using the content analysis technique. Results were evaluated using the concept of majority and minority group and presented in a sequential way: teachers' perceptions about eating habits, barriers to healthy eating, teacher's culinary habits, abilities to teach students healthy eating habits through Information and Communication Technologies, and cooking activities. Teachers' eating habits were poor, with lack of time, money, and will to improve. They had culinary habits skills and the desire to instruct and guide their students in eating healthier food. They need a program with Information and Communication Technologies and cooking workshops to apply in the classroom.

Loose Anchoring of Anagen Hairs and Pili Torti due to Erlotinib.

Erlotinib is a selective epidermal growth factor receptor inhibitor utilized in the treatment of solid tumors. Cutaneous side effects, including changes in hair texture and alopecia, have been described. In this case report, we describe two patients with a new finding of loose anagen hairs and pili torti leading to nonscarring marginal and diffuse alopecia and discuss potential mechanisms underlying erlotinib-induced hair changes.

[Validity of an instrument for assessing food consumption, food habits and cooking skills in 8-11 years old students]. / VALIDACIÓN DE UN INSTRUMENTO PARA EVALUAR CONSUMO, HÁBITOS Y PRÁCTICAS ALIMENTARIAS EN ESCOLARES DE 8 A 11 AÑOS.

INTRODUCTION: An instrument to measure food knowledge, food consumption, cooking skills, food habits and food expenses at school is necessary to assess changes in food practices. OBJECTIVE: To validate an instrument to measure changes in food knowledge, food consumption, cooking skills, food habits and food expenses in Chilean school children 8 - 11 years from third to fifth grade. METHODS: A validation of a questionnaire with 42 questions was conducted in two stages: the first to assess temporal stability, concordance and internal consistency in 45 children. The second one to apply the survey, modified with the results of the first stage, in 90 children assessing internal consistency. RESULTS: The first survey with 42 questions showed a reasonable temporal stability, concordance and internal consistency for cooking skills, habits and food expenditure at school. Internal consistency was good for food consumption, but not so good for food knowledge. In the final validation with 90 children, there was good consistency for food consumption but bad for food knowledge. Besides, children with cooking skills ate more healthy food and those who expended more money at school, consumed less healthy food. CONCLUSIONS: Food knowledge questions were eliminated from the instrument, which was elaborated with 28 questions about food consumption, cooking skills, food habits and food expenses at school. This instrument is useful to assess changes in food and nutrition education interventions in 8 -11 years children, in particular to measure cooking skills and food expenses at school.

Introducción: Para medir cambios en prácticas alimentarias, se requieren instrumentos que midan conocimiento, consumo, habilidades culinarias, hábitos y gastos en alimentos en las escuelas. Objetivo: Validar un instrumento que permita medir cambios en conocimiento, consumo, habilidades culinarias, hábitos y gastos en niños de 8 a 11 años, de tercero a quinto básico, en escuelas públicas de Chile. Métodos: Se realizó un estudio de validación de un cuestionario de 42 preguntas de conocimiento, consumo, habilidades culinarias, hábitos y gastos en la escuela. Se realizó en dos etapas: la primera en 45 niños para evaluar la estabilidad temporal, concordancia y consistencia interna. La segunda fue aplicar el instrumento modificado con los resultados de la primera etapa en 90 niños para medir consistencia interna. Resultados: El cuestionario aplicado en los 45 niños mostró estabilidad temporal, concordancia y consistencia interna aceptables para habilidades culinarias, hábitos y gastos en la escuela. La consistencia fue buena para frecuencia de consumo, pero mala en conocimiento. En la validación final con 90 niños, se confirmó la buena consistencia para frecuencia de consumo y mala para conocimiento. Se observó que aquellos niños con habilidades culinarias, consumen más alimentos saludables y los que gastan más dinero en la escuela, consumen menos alimentos saludables. Conclusiones: Al instrumento se le quitaron las preguntas de conocimiento, quedando con 28 preguntas de consumo, habilidades culinarias, hábitos y gasto en alimentos en las escuelas. Este instrumento es útil para medir cambios en intervenciones educativas en alimentación y nutrición en niños de 8 a 11 años.

Aplicación y efectividad de un modelo educativo en hábitos saludables con entrega de fruta y programa de actividad física en escolares

RESUMEN El objetivo fue evaluar una intervención educativa en hábitos de alimentación saludable basada en el programa Colación BKN en pre-escolares y escolares entre los años 2013-2018. Diseño longitudinal con comparación de cortes trasversales en escolares de prekínder a cuarto año básico durante 4 años en 14 escuelas de la Región Metropolitana de Chile. El programa consistió en entrega de fruta como colación, educación alimentaria, mejora de la actividad física y kioscos escolares, con participación de profesores y familias. Como resultado se observó una mejoría de los conocimientos en alimentación saludable de los niños, con una excelente satisfacción de usuarios. Sobrepeso y obesidad se mantuvieron el 2016 y 2018, pero aumentaron el 2015 y 2017. En escuelas similares no intervenidas el exceso de peso fue mayor con respecto a las del programa. Hubo una tendencia a disminuir el consumo de dulces y bebidas azucaradas en prekínder y kínder entre 2014 y 2017 y el consumo de 3 porciones al día de frutas y verduras en niños intervenidos fue superior al promedio nacional de 2 porciones al día.Conclusiones: Hubo un aumento exitoso en el consumo de frutas y verduras, educación alimentaria y actividad física para el cambio hacia hábitos más saludables.

ABSTRACT The objective was to evaluate an educational intervention for healthy eating habits based on the Colación BKN program, among preschool and schoolchildren, carried out in 2013-2018. We conducted a longitudinal study with cross-sectional data among preschool and school-age children (up to the fourth grade) over four years in 14 schools in the Metropolitan Region of Chile. The intervention program consisted of fruit delivery, nutrition education and improvements in physical activity and school food kiosks, with active participation of teachers and parents. There was an improvement in knowledge of healthy foods in children and excellent user satisfaction. Overweight and obesity did not increase during 2016 and 2018, but increased in 2015 and 2017. In similar not-intervened schools there was an increase of overweight and obesity compared with Colación BKN schools. For food consumption, there was a decrease in consumption of candy and soft drinks in preschool students and all children consumed more than three portions of fruits and vegetables per day, which is greater than the national average of two portions per day in the general population. Conclusions: There was a successful increase in fruit and vegetable consumption with nutrition education and promotion of healthy habits, such as physical activity and healthy food consumption.
