RESUMO
BACKGROUND: In kidney damage, molecular changes can be used as early damage kidney biomarkers, such as Kidney Injury Molecule-1 and Neutrophil gelatinase-associated lipocalin. These biomarkers are associated with toxic metal exposure or disturbed homeostasis of trace elements, which might lead to serious health hazards. This study aimed to evaluate the relationship between exposure to trace elements and early damage kidney biomarkers in a pediatric population. METHODS: In Tlaxcala, a cross-sectional study was conducted on 914 healthy individuals. The participants underwent a medical review and a socio-environmental questionnaire. Five early damage kidney biomarkers were determined in the urine with Luminex, and molybdenum, copper, selenium, nickel, and iodine were measured with ICP-Mass. RESULTS: The eGFR showed a median of 103.75 mL/min/1.73 m2. The median levels for molybdenum, copper, selenium, nickel, and iodine were 24.73 ng/mL, 73.35 ng/mL, 4.78 ng/mL, 83.68 ng/mL, and 361.83 ng/mL, respectively. Except for molybdenum and nickel, the other trace elements had significant associations with the eGFR and the early kidney damage biomarkers. Additionally, we report the association of different exposure scenarios with renal parameters. DISCUSSION: and Conclusions. Among the explored metals, exposure to Cu and iodine impairs renal function. In contrast, Se may manifest as a beneficial metal. Interactions of Mo-Se and Mo-Iodine seem to alter the expression of NGAL; Mo-Cu for CLU; Mo-Cu, Mo-Se, and Mo-iodine for Cys-C and a-1MG; and Mo-Cu and Mo-iodine for KIM-1; were noticed. Our study could suggest that trace element interactions were associated with early kidney damage biomarkers.

Introduction: Energy imbalance gap (EIG) is defined as the average daily difference between energy intake (EI) and energy expenditure (EE). This study aimed to examine the associations between EIG and sociodemographic and anthropometric variables in the adolescent population of eight Latin America countries. Methods: A total of 680 adolescents aged 15 to 18 were included in this study. The estimation of EI was based on two non-consecutive 24-h dietary recalls. EE was predicted from Schofield equations using physical activity level obtained through the long version of the International Physical Activity Questionnaire. Sociodemographic data and anthropometric measurements were also obtained. A descriptive analysis and multilevel linear regression models were used to examine associations between variables. Results: The mean EI, EE, and EIG were 2091.3 kcal, 2067.8 kcal, and 23.5 kcal, respectively. Argentina had the highest EI and EIG, whereas Chile had the lowest EI and EIG. Males had a higher EI (2262.4 kcal) and EE (2172.2 kcal) than females (1930.1 kcal and 2084.5 kcal), respectively (p < 0.05). Overweight subjects had a lower EIG than did underweight and normal-weight subjects (p < 0.05). Subjects with low socioeconomic status (SES) had a lower EE (2047.0 kcal) than those with a high SES (2164.2 kcal) (p < 0.05). Conclusion: Sex and BMI were associated with EIG in adolescents from Latin America.
RESUMO
To explore the existing literature on the effect of Interprofessional Education (IPE) on the work environment of health professionals. The research question was systematized according to the PCC (Population, Concept, and Context) format. A scoping review was performed. A search of multiple bibliographic databases identified 407 papers, of which 21 met the inclusion criteria. The populations of the 21 studies reviewed were composed of professionals in the fields of medicine, nursing, psychology, occupational therapy, physiotherapy, and social work, among others. The study contexts were both academic and nonacademic hospitals, mental health institutions, and community settings, and the topics examined were organizational climate, organizational culture, organizational attachment and job satisfaction. The findings from the reviewed studies showed positive effects of IPE interventions on organizational climate and culture, but the results on job satisfaction and organizational attachment were mixed (i.e., positive and no effects following IPE interventions). Research on IPE is worth more attention as IPE could be an effective alternative for the fulfillment of the Quadruple Aim and achieving the third of the United Nations Sustainable Development Goals, aimed at improving health and well-being. It seems critical for IPE to be positioned as a trend in global health, aiming at boosting human health resources as one of its building blocks and calling the attention of health decision-makers.
RESUMO
The largest public space in any city is its streets. Investments which incorporate small-scale green infrastructure into streetscapes can bring more nature into the lives of urban residents worldwide, including those living in even the most economically and spatially constraint places. However, little is known about the impact of such small-scale investments on urban residents' affective perceptions of their local environments and how to design these investments to maximise their positive impacts. In the current study, we use photo simulation techniques and an adapted form of the Positive and Negative Affective Schedule to examine the impact of small-scale green infrastructure interventions on the affective perceptions of low, middle and high-income sites in Santiago Chile. Our results, based on 62,478 reports of affective perceptions from 3,472 people, indicate that green infrastructure investments can both promote positive affect and, to a lesser, but still substantial extent reduce negative affect. The magnitudes of these relationships vary across discrete affective measures and for many of these measures, both positive and negative, a minimum of 16% increase in green coverage is required to see an impact. Finally, we find people associated lower affect with low, compared to middle and high, income sites but that these affective inequalities can be addressed, at least in part, through green infrastructure interventions.

BACKGROUND: Although COVID-19 (coronavirus disease 2019) in children is usually mild, they need hospitalization and intensive care in exceptional cases. Adverse outcomes have been observed mainly among children with comorbidities, justifying their vaccination. This study aimed to assess the risk of hospitalization and death in Mexican children and adolescents with COVID-19 and comorbidities. METHODS: A cross-sectional study was performed on 366,542 confirmed COVID-19 cases under 18 years, reported by the Mexican Ministry of Health up to July 9, 2022. Logistic regression models were performed. RESULTS: The mean age was 10.98 years, 50.6% were male, and 7.3% reported at least one comorbidity. The percentage of hospitalization and death in COVID-19 patients with and without comorbidities was 3.52%, and 0.20%, respectively; children with comorbidities presented a higher percentage of hospitalization (14.0%) and death (1.9%). The probability of hospitalization was 5.6 times greater in pediatric patients with COVID-19 and comorbidities, and the comorbidities that showed the greatest risk were immunosuppression (odds ratio (OR) 22.06), chronic kidney disease (CKD) (11.36), and cardiovascular diseases (5.66). The probability of death in patients with comorbidities was 11.01 times higher than in those without diseases, and the highest risk was observed in those with CKD (OR 12.57), cardiovascular diseases (6.87), and diabetes (5.83). CONCLUSIONS: Pediatric patients with comorbidities presented a higher risk of severe COVID-19. It is suggested that vaccination should be promoted with greater emphasis on pediatric patients with comorbidities.
INTRODUCCIÓN: Aunque COVID-19 (enfermedad por coronavirus 2019) en niños es usualmente leve, en casos excepcionales requieren hospitalización y cuidados intensivos. Los resultados adversos han sido observados principalmente en los niños con comorbilidades, justificando su vacunación. El objetivo de este estudio fue evaluar el riesgo de hospitalización y muerte en niños y adolescentes mexicanos con COVID-19 y comorbilidades. MÉTODOS: Estudio transversal en 366,542 casos de COVID-19 confirmados, menores de 18 años y reportados por la Secretaría de Salud de México, hasta el 9 de julio del 2022. Se ejecutaron modelos multivariados de regresión logística. RESULTADOS: El promedio de edad fue de 10.98 años, 50.6% de sexo masculino, y 7.3% reportaron al menos una comorbilidad. El porcentaje de hospitalización y muerte en pacientes con COVID-19 sin comorbilidades fue 3.52% y 0.20%, respectivamente; mientras que los pacientes con comorbilidades presentaron más elevados porcentajes de hospitalización (14.0%) y muerte (1.9%). La probabilidad de hospitalización fue 5.6 veces más en los pacientes con COVID-19 y comorbilidades, comparando con aquellos sin comorbilidades. Las comorbilidades que mostraron más riesgo fueron inmunosupresión (razón de momios (RM) 22.06), enfermedad renal crónica (ERC) (RM 11.36) y enfermedades cardiovasculares (RM 5.66). La probabilidad de muerte en los pacientes con comorbilidades fue 11.01 veces más que en aquellos sin enfermedades, y fue más elevado en aquellos con ERC (RM 12.57), enfermedades cardiovasculares (RM 6.87) y diabetes (RM 5.83). CONCLUSIONES: Los pacientes pediátricos con comorbilidades presentaron mayor riesgo de COVID-19 severo, por lo que se sugiere promover con mayor énfasis la vacunación en ellos.

BACKGROUND: In recent years, chronic kidney disease has increased in the pediatric population and has been related to environmental factors. In the diagnosis of kidney damage, in addition to the traditional parameters, early kidney damage biomarkers, such as kidney injury molecule 1, cystatin C, and osteopontin, among others, have been implemented as predictors of early pathological processes. OBJECTIVE: This study aimed to evaluate the relationship between exposure to environmental pollutants and early kidney damage biomarkers. METHODS: A cross-sectional pilot study was conducted in February 2016 and involved 115 apparently healthy children aged 6-15 residing in Apizaco, Tlaxcala. Participant selection was carried out randomly from among 16,472 children from the municipality of Apizaco. A socio-demographic questionnaire included age, sex, education, duration of residence in the area, occupation, water consumption and dietary habits, pathological history, and some non-specific symptoms. Physical examination included blood pressure, weight, and height. The urine concentrations of urinary aluminum, total arsenic, boron, calcium, chromium, copper, mercury, potassium, sodium, magnesium, manganese, molybdenum, lead, selenium, silicon, thallium, vanadium, uranium, and zinc, were measured. Four of the 115 participants selected for the study were excluded due to an incomplete questionnaire or lack of a medical examination, leaving a final sample population of 111 participants. RESULTS: The results showed a mean estimated glomerular filtration rate of 89.1 ± 9.98 mL/min/1.73m2 and a mean albumin/creatinine ratio of 12.9 ± 16.7 mg/g urinary creatinine. We observed a positive and significant correlation between estimated glomerular filtration rate with fluoride, total arsenic and lead, and a correlation of albumin/creatinine ratio with fluoride, vanadium, and total arsenic. There was also a significant correlation between the early kidney damage biomarkers and fluoride, vanadium, and total arsenic, except for cystatin C. CONCLUSION: In conclusion, our results show that four urinary biomarkers: α1-microglobulin, cystatin C, kidney injury molecule 1, and neutrophil gelatinase-associated lipocalin are related to environmental exposure to urinary fluoride, vanadium, and total arsenic in our pediatric population.

RESUMO
Dietary protein intake is vital to life. Here we sought to characterize dietary sources of protein in eight Latin American countries. Survey data were collected for Estudio Latinoamericano de Nutrición y Salud (ELANS); participants were from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela (n = 9218, 15-65 years old). The primary aim of this analysis was to quantify per-person daily protein consumption by country and sociodemographic factors. Secondary aims: to quantify proportional intake of proteins by source, amount and processing, and to determine the adequacy of protein/essential amino acid intake. Younger groups (adolescents 15-19 years, adults 20-33 years) had the highest intake of proteins; middle-aged adults (34-49 years) had a lower intake, and older adults (50-65 years) had a strikingly lower intake. Protein consumption was higher in men than women. Animal proteins comprised nearly 70% of total daily protein intake in Argentina and Venezuela, contrasting with <60% in Peru, Chile, and Costa Rica. Brazil and Venezuela showed the highest protein intake within the highest education level. The higher the socioeconomic level, the higher the protein intake, except for Argentina, Chile, and Peru. Proportional intake of animal- and plant-based protein generally reflected the food availability by country. This study presents a pre-pandemic regional baseline and offers a perspective for future studies of changes related to government policies, climate, and dietary practices.

RESUMEN Introducción: La anorexia nerviosa plantea un importante problema bioético, ya que los pacientes, a menudo, rechazan el tratamiento a pesar del peligro que ello supone para su salud, y no está claro que su decisión sea autónoma. El objetivo de este trabajo es investigar las percepciones/actuación de psiquiatras y psicólogos clínicos ante la capacidad y el internamiento involuntario de pacientes con anorexia nerviosa. Métodos: Se entrevistó a 7 psiquiatras, 4 psicólogas clínicas y 1 psicóloga residente de tercer año. Se utilizó un enfoque de investigación cualitativa basado en la teoría fundamentada. Resultados: El análisis de datos mostró que estos profesionales articulan la atención del paciente en torno a una categoría principal, a saber, el internamiento como último recurso y la búsqueda de la voluntariedad, lo que implica un cambio en la dinámica asistencial habitual. En torno a esa categoría central, se erigen algunos conceptos importantes; estrés de rol, coerción informal, peso, familia y cronicidad. Conclusiones: La dificultad de conciliar demandas profesionales puede suponer un menoscabo en la calidad de la asistencia y en la propia satisfacción laboral, lo que pone en evidencia la necesidad de reflexionar e investigar sobre los fundamentos de las atribuciones asumidas.
ABSTRACT Introduction: Anorexia nervosa poses an important bioethical quandary, since patients often refuse treatment despite the danger that this poses to their health, and it is not clear that their decision is autonomous. The aim of this study was to investigate the perceptions/performance of psychiatrists and clinical psychologists regarding the capacity and involuntary hospitalisation of patients with anorexia nervosa. Methods: Seven psychiatrists, four clinical psychologists, and one third-year resident psychologist were interviewed. A qualitative research approach based on grounded theory was used. Results: The data analysis showed that these professionals articulate patient care around one main category - hospitalisation as a last resort and the search for voluntariness, which implies a change in the usual healthcare dynamics. Around this central category, some important concepts emerge: role stress, informal coercion, weight, family and chronicity. Conclusions: The difficulty of reconciling professional demands can undermine the quality of care and job satisfaction itself, which highlights the need for reflection and research into the foundations of the responsibilities assumed.
RESUMO
RESUMEN Introducción: La anorexia nerviosa es un trastorno grave que causa tasas elevadas de morbilidad y mortalidad. La aplicación de una intervención no voluntaria solo es legalmente admisible si el paciente no es competente. Sin embargo, la evaluación de su capacidad puede ser extremadamente compleja. Ello conlleva que la decisión final pueda verse influida por las actitudes individuales del facultativo. Objetivo: Crear y validar empíricamente un cuestionario en español que permita medir la actitud hacia la capacidad y el internamiento no voluntario y comparar entre grupos categóricos. Métodos: Formaron la muestra 338 profesionales de salud mental. Los ítems fueron validados por grupos de expertos. Se realizaron un análisis factorial exploratorio y comparaciones grupales. Resultados: Se obtuvo un modelo de 13 ítems formado por 3 factores: prointervención, ausencia de capacidad y cronicidad. Los profesionales tienden a creer en la ausencia de capacidad y la necesidad de la intervención no voluntaria, así como en la idoneidad diferencial en virtud de la cronicidad. El respaldo previo a intervenciones involuntarias se relacionó significativamente con los factores prointervención y ausencia de capacidad y la formación en bioética, con la cronicidad. Conclusiones: El instrumento resultante es válido y fiable. Puede ser útil a profesionales, pacientes y sociedad.
ABSTRACT Introduction: Anorexia nervosa is a serious disorder that causes high rates of morbidity and mortality. Involuntary treatments are only legally admissible if the patient is not competent. However, assessing their capacity can be really complex. This implies that the final decision might be influenced by the individual attitudes of the physician. Objective: To create and empirically validate a questionnaire in Spanish that makes it possible to measure the attitude towards capacity and involuntary commitment and compare between categorical groups. Methods: The sample consisted of 338 mental health professionals. The items were validated by groups of experts. An exploratory factor analysis and group comparisons were carried out. Results: Favourable evidence was obtained of a 13-item model consisting of three factors: pro-intervention, lack of capacity and chronicity. Professionals tend to believe in the lack of capacity and the need for involuntary interventions, as well as differential suitability due to chronicity. Having ever supported involuntary interventions was significantly related to the pro-intervention and lack of capacity factors, and training in bioethics to chronicity. Conclusions: The resulting instrument is valid and reliable. Its use can be useful to professionals, patients and society.
