Conocimiento sobre prevención del embarazo en adolescentes mexicanos / Knowledge about pregnancy prevention in Mexican adolescents

Resumen Objetivo: Establecer la relación entre el conocimiento sobre prevención de embarazo, edad de inicio de vida sexual, cantidad de métodos anticonceptivos utilizados alguna vez y características personales del adolescente como sexo, edad y escolaridad. Materiales y métodos: Estudio descriptivo, correlacional de corte transversal, participaron 2509 adolescentes mexicanos de 14 a 19 años de edad. Se emplearon los reactivos que miden el conocimiento en las dimensiones salud sexual, salud reproductiva y uso del condón de la escala psicométrica de conocimientos, actitudes y prácticas en salud sexual y salud reproductiva. Resultados: Se obtuvo una media de conocimiento sobre prevención de embarazo de 17.21 (DE = 4.72) de valores de 0-27. El conocimiento se relaciona significativamente con la edad del adolescente (r = 0.325; p = 0.01), con la cantidad de métodos anticonceptivos que utilizan (r = 0.210; p = 0.01) y una relación incipiente con la edad de IVS (r = 0.074; p = 0.01). El conocimiento es ligeramente mayor en las mujeres (M = 17.42; DE = 4.58) respecto a los hombres (M = 16.92; DE = 4.89), así como en los adolescentes universitarios (M = 18.71; DE = 4.19). Los adolescentes que utilizan 3 o más métodos anticonceptivos, mostraron mayor conocimiento (M = 19.46; DE = 4.11). Conclusiones: El conocimiento sobre prevención de embarazo es mayor conforme aumenta la edad, la edad de inicio de vida sexual y la escolaridad. Los hallazgos resultan de importancia para desarrollar estrategias de información sobre métodos anticonceptivos y salud sexual y reproductiva, de una forma accesible e igualitaria en mujeres y hombres desde edades tempranas y en escolaridad básica, con la intención de que el adolescente sea responsable desde el inicio de su vida sexual y de prevenir y postergar un embarazo a través del conocimiento como herramienta fundamental.

Abstract Objective: Establish the relationship between knowledge of pregnancy prevention, age of sexual debut, number of contraceptive methods ever used and personal characteristics of the adolescent such as sex, age and schooling. Materials and methods: A descriptive, cross-sectional, correlational, cross-sectional study, 2509 Mexican adolescents aged 14 to 19 years participated. The items measuring knowledge in the dimensions of sexual health, reproductive health and condom use of the psychometric scale of knowledge, attitudes and practices in sexual and reproductive health were used. Results: The mean knowledge of pregnancy prevention was 17.21 (SD = 4.72) from 0-27. Knowledge is significantly related to adolescent age (r = 0.325; p = 0.01), to the number of contraceptive methods used (r = 0.210; p = 0.01) and an incipient relationship with age at sexual debut (r = 0.074; p = 0.01). Knowledge is slightly higher in females (M = 17.42; SD = 4.58) relative to males (M = 16.92; SD = 4.89), as well as in college adolescents (M = 18.71; SD = 4.19). Adolescents using 3 or more contraceptive methods showed greater knowledge (M = 19.46; SD = 4.11). Conclusions: Knowledge about pregnancy prevention increases with age, age at sexual debut and schooling. The findings are important to develop information strategies on contraceptive methods and sexual and reproductive health, in an accessible and egalitarian way for women and men from an early age and in basic schooling, with the intention that the adolescent is responsible from the beginning of sexual life to prevent and postpone pregnancy through knowledge as a fundamental tool.

Impacto de una intervención de educación prenatal en mujeres embarazadas para prevenir el sobrepeso en lactantes / Impact of a prenatal education intervention in pregnant women to prevent overweight in infants

Resumen Introducción: Durante los primeros 1000 días de vida se establece la base para la salud futura de un niño. Objetivo: Evaluar el impacto de una intervención educativa prenatal en mujeres embarazadas sobre el estado nutricional del hijo desde el nacimiento hasta los cuatro meses de edad. Métodos: Diseño cuasiexperimental de intervención con mujeres a partir de la semana 12 de gestación, asignadas aleatoriamente a un grupo de intervención (GI) para recibir cinco sesiones grupales y tres individuales sobre prácticas de alimentación y percepción materna del peso del hijo y de señales de hambre-saciedad; el grupo control (GC) recibió atención de rutina que incluía al menos tres consultas prenatales. Resultados: 30 mujeres conformaron cada grupo. Después de la intervención, las mujeres del GC practicaron menos lactancia materna exclusiva, fueron propensas a subestimar o sobrestimar el peso del hijo y percibieron con menor intensidad las señales de hambre-saciedad (p < 0.05). El 80 % de los lactantes del GI presentaron peso normal y 63 % de los niños del GC, una combinación de sobrepeso y obesidad (p < 0.05). Conclusiones: El programa de educación prenatal en mujeres embarazadas mostró un efecto significativo en el estado nutricional de los lactantes después de cuatro meses del nacimiento.

Abstract Introduction: During the first 1000 days of life is the basis for a child‘s future health established. Objective: To evaluate the impact of a prenatal educational intervention in pregnant women on the nutritional status of the child from birth to 4 months of age. Methods: Quasi-experimental intervention design in women with at least 12 weeks of gestation, who were randomly assigned to an intervention group (IG) to participate in five group and three individual sessions on feeding practices and maternal perception of the child’s weight and signals of hunger-satiety; the control group (CG) received routine care that included at least three prenatal consultations. Results: Thirty women were included in each group. After the intervention, women in the CG practiced less exclusive breastfeeding, were more likely to underestimate and overestimate the children’s weight, and perceived hunger-satiety signals with less intensity (p < 0.05). 80 % of the infants in the IG had normal weight, whereas 63 % of those in the CG had a combination of overweight and obesity (p < 0.05). Conclusions: The prenatal education program in pregnant women showed a significant effect on postnatal nutritional status of infants four months after birth.

Burnout and resilience of internal medicine physician trainees in a tertiary government hospital in the Philippines during the COVID-19 pandemic: A Mixed-method study

@#<p style="text-align: justify;"><strong>Objectives:</strong> Internal Medicine physician trainees faced unique challenges as the primary frontline physicians at a tertiary COVID-19 government referral center during the COVID-19 pandemic. This study examined the prevalence of burnout and resilience of these physician trainees during the early period of the pandemic, the determinants of burnout, and their sources of anxiety and coping mechanisms.</p><p style="text-align: justify;"><strong>Methods:</strong> Using a mixed-methods approach, we conducted an online cross-sectional survey to measure burnout and resilience among 196 Internal Medicine physician trainees using the Maslach Burnout Index Human Services Survey for Medical Personnel and the Connor-Davidson Resiliency questionnaires, respectively. We then conducted virtual focus group discussions and in-depth key informant interviews to explore the trainees' sources of anxiety and coping mechanisms until thematic saturation was satisfied.</p><p style="text-align: justify;"><strong>Results:</strong> Out of 146 respondents (from 196 eligible participants, 74% response rate), four percent of physician trainees fit the frank burnout profile, 40% were engaged, while the majority had intermediate profiles (23% ineffective, 28% overextended, and 4% disengaged). The mean resilience score was 72.9 (SD 12.4). Resilience was a significant negative predictor for burnout (Beta Coefficient = -0.73, p<0.001). Its protective effect decreases in those with more exposure to patient deaths (Beta Coefficient = 6.767, p<0.05). Significant sources of anxiety included changes in the practice of medicine (changes in workflow, working in full personal protective equipment, telemedicine and zoom fatigue, constant threat of acquiring the infection) and having competing demands between service and training. Coping mechanisms included preserving a haven, maintaining social relationships, and self-care.</p><p style="text-align: justify;"><strong>Conclusion:</strong> In the largest government hospital in the Philippines, four percent of Internal Medicine physician trainees had burnout, 40% were engaged, and the majority were at-risk for burnout a few months into the COVID-19 pandemic in 2020. Resilience reduces the risk for burnout. However, its protective effect decreased with exposure to a higher number of patient deaths per week.</p>

Sensibilidad in vitro de cepas cubanas de Aspergillus spp. de origen clínico y ambiental / In vitro susceptibility of Cuban Aspergillus spp. strains of clinical and environmental origin

Introducción. En Cuba se desconoce el comportamiento de la sensibilidad de Aspergillus spp. a los antifúngicos recomendados para el tratamiento de la aspergilosis: la anfotericina B, el itraconazol, el voriconazol y las equinocandinas. La influencia del ambiente puede condicionar la aparición de resistencia en estos microorganismos. Objetivo. Evaluar la sensibilidad in vitro de cepas de Aspergillus spp. a la anfotericina B, el itraconazol y el voriconazol, y la relación de los patrones de sensibilidad con su origen. Materiales y métodos. Se determinaron las concentraciones inhibitorias mínimas de la anfotericina B, el itraconazol y el voriconazol para 60 cepas de Aspergillus spp. de origen clínico y ambiental mediante el método M38-A2 del Clinical and Laboratory Standard Institute. Resultados. Se encontraron 21 cepas resistentes a la anfotericina B (principalmente en muestras clínicas y ambientes hospitalarios) y tres cepas resistentes al itraconazol (en ambientes interiores y exteriores no hospitalarios). No se hallaron cepas resistentes al voriconazol. No se encontró relación entre el origen de las cepas y su sensibilidad. Conclusiones. Se sugiere la posible existencia de factores ambientales o interacciones con genotipos resistentes que pueden dar origen a fenotipos resistentes en Cuba. Este es el primer reporte del país de cepas de Aspergillus spp. resistentes in vitro. Los resultados ameritan ampliar el estudio para incluir análisis moleculares y filogenéticos.

Introduction: The behavior of antifungal susceptibility of Aspergillus spp. in Cuba remains unknown. The antifungals recommended to treat aspergillosis are amphotericin B, itraconazole, voriconazole and echinocandins. The influence of the environment may set off the emergence of drug-resistance in these microorganisms. Objective: To evaluate in vitro susceptibility of Aspergillus spp. strains to amphotericin B, itraconazole and voriconazol, and the relationship between susceptibility patterns and their origin. Materials and methods: Minimum inhibitory concentrations of amphotericin B, itraconazole and voriconazole were determined for 60 Aspergillus spp. strains of clinical and environmental origin using the M38-A2 method of the Clinical and Laboratory Standards Institute. Results: We found 21 amphotericin B resistant strains (mainly from clinical samples and hospital environments), as well as three itraconazole resistant strains (from non-hospital outdoor and indoor environments). No voriconazole resistance was found. No relationship was found between strain origin and susceptibility. Conclusions: Results suggest the possible existence of environmental factors or interactions with resistant genotypes which may give rise to resistant phenotypes in our country. This is the first report of in vitro Aspergillus spp. resistant strains in Cuba. These studies should be broadened and include molecular and phylogenetic analyses.

Predictores maternos del índice de masa corporal del hijo pre-escolar y escolar / Maternal Predictors of Body Mass Index of pre-school and school age children.

El objetivo fue identificar variables maternas predictoras del índice de masa corporal (IMC) del hijo. Se consideraron variables: a) socio-demográficas (edad, escolaridad, ocupación, estado marital e ingreso económico familiar), b) antropométricas (IMC) y c) estrategias de crianza (monitoreo y límites en alimentación, monitoreo y límites de conductas sedentarias, disciplina y control en alimentación). Se realizó un estudio correlacional predictivo con 537 diadas (madre-hijo). Los hijos inscritos en 4 escuelas públicas (2 de nivel pre-escolar y 2 de primaria) fueron seleccionados por muestreo aleatorio probabilístico. Las madres respondieron la Escala Estrategias de Crianza de Alimentación y Actividad, proporcionaron información socio demográfica y se midió peso y talla a cada diada. Los datos se analizaron por correlaciones y análisis de senderos. Se encontró que las madres tenían edad promedio de 34.25 años (DE=6.91), escolaridad 12.40 años (DE=3.36). El 53.3% refirió ser ama de casa y el 46.7% tener trabajo remunerado fuera del hogar. El 38.5% presentó pre-obesidad y el 27.3% algún grado de obesidad. La edad promedio del hijo fue 7.26 años (DE =2.46). El 3.2% presentó bajo peso, el 59.6% peso normal y el 37.2% sobrepeso-obesidad. Se encontró que trabajar fuera del hogar, tener mayor IMC materno, menor control y mayor disciplina en la alimentación son variables predictoras de mayor IMC del hijo. Se recomienda diseñar intervenciones para reducir y tratar el sobrepeso-obesidad infantil considerando los predictores encontrados.

The objective was to identify maternal variables that could be used as predictors of the child’s body mass index (BMI). We considered the following variables: a) socio-demographic (age, education, occupation, marital status and family income); b) anthropometric (BMI); and c) upbringing strategies (monitoring and limits for eating habits, monitoring and sedentary behavior limits, discipline and control in feeding. A predictive correlational study was carried out with 537 dyads (motherchild). Children enrolled in 4 public schools (2 for pre-school children and 2 for primary school children) were selected for probabilistic, random sampling. The mothers answered the Feeding and Activity Upbringing Strategies Scale, giving socio-demographic information and the dyads’ weight and height was measured. The data were analyzed for correlations and path analysis. It was found that the average age of mothers was 34.25 years (SD=6.91), with 12.40 years of education (SD=3.36), 53.3% mentioned that they were housewives and 46.7% had a paid job outside of the home; 38.5% showed pre-OB and 27.3% some degree of OB. The child’s average age was 7.26 years (SD=2.46), and 3.2% showed low weight, 59.6% normal weight and 37.2% OW-OB. It was found that working outside the home, having a higher maternal BMI, less control and more discipline in feeding are variables that predict higher BMI in the child. We recommend the design of interventions to reduce and treat the child’s OW-OB taking into account the predictors that were found.

Capilaroscopia periungueal: relevância para a prática reumatológica / Nailfold capillaroscopy: relevance to the practice of rheumatology

A capilaroscopia periungueal é um método simples, de baixo custo, e de extrema relevância na avaliação de pacientes com fenômeno de Raynaud ou portadores de doenças do espectro da esclerose sistêmica (ES). Além de sua importância para o diagnóstico precoce da ES, constitui instrumento útil na identificação de pacientes esclerodérmicos com risco elevado para o desenvolvimento de complicações vasculares, viscerais e de óbito. A inclusão da capilaroscopia nos novos critérios para classificação da ES do Colégio Americano de Reumatologia (ACR) e da Liga Europeia Contra o Reumatismo (Eular) dá novo impulso para a utilização e disseminação do método. No presente artigo, pretendemos apresentar uma revisão didática, não sistemática, sobre o tema, com ênfase nos avanços recentemente descritos.

Nailfold capillaroscopy is a simple, low-cost method, that is extremely important in the evaluation of patients with Raynaud's phenomenon and of patients with systemic sclerosis (SSc) spectrum diseases. Besides its importance for the early diagnosis of SSc, nailfold capillaroscopy is a useful tool to identify scleroderma patients with high risk for development of vascular and visceral complications and death. The inclusion of capillaroscopy in the new classification criteria for SSc of the American College of Rheumatology (ACR) and European League Against Rheumatism (Eular) gives a new impetus to the use and dissemination of the method. In this paper, we present a didactic, non-systematic review on the subject, with emphasis on advances recently described.

Síndrome de Felty e Calazar: um desafio para o reumatologista / Felty's syndrome and Kala-azar: a challenge for the rheumatologist

Os autores relatam o caso de uma paciente com artrite reumatoide que evoluiu com grave neutropenia e esplenomegalia, sendo firmado o diagnóstico de Síndrome de Felty, que posteriormente desenvolveu Calazar. Ambas têm apresentação clínica e laboratorial semelhantes, tornando o diagnóstico diferencial difícil. O relato deste caso objetiva chamar a atenção para o reconhecimento da infecção por leishmaniose visceral em pacientes portadores de doenças reumáticas, assim como a possibilidade de um paciente com Calazar mimetizar um quadro de doença reumática sistêmica.

Case report of a patient with rheumatoid arthritis who developed severe neutropenia, splenomegaly and was diagnosed with Felty's syndrome. The patient later developed Kala-azar. Both diseases have similar clinical and laboratory presentation, making the differential diagnosis difficult. The present case report aims at drawing attention to the identification of visceral Leishmaniasis infection in patients with rheumatic diseases, as well as possibility of a patient with Kala-azar mimicking a set of symptoms of systemic rheumatic disease.

Avaliação da produção de espécies reativas de oxigênio por granulócitos de sangue periférico de pacientes com fibromialgia primária / Assessment of reactive oxygen species production by peripheral blood granulocytes from primary fibromyalgia patients

Obejetivo: avaliar anormalidades bioquímicas que possam estar relcionadas à fibromialgia, mais especificamente o metabolismo oxidante de granulócitos de pacientes com fibromialgia primária (FMP). Métodos: foram selecionados 10 pacientes (9 mulheres e 1 homem) portadores de FMP, com idade entre 20 e 40 anos, de acordo com os critérios do Colégio Americano de Reumatologia, que não apresentavam qualquer outra doença de curso agudo ou crônico e estavam sem utilizar medicamentos no mínimo durante duas semanas. Controles normais (n = 19) pareados por sexo e idade foram selecionados. Os granulócitos de pacientes e controles foram separados do sangue periférico e utilizados como célula de trabalho. A produção de espécies reativas de oxigênio (ERO) foi determinada por meio de ensaio de quimioluminescência dependente de luminol. Resultados: demonstramos, pela primeira vez, uma produção significantemente elevada de ERO (3,2 vezes maior) em granulócitos de sangue periférico de pacientes com FMP (< 0,05). Conclusões: estes resultados demonstraram um comportamento anormal dos granulócitos de pacientes com FMP, em que uma produção aumentada de espécies reativas do oxigênio foi observada. Estudos futuros serão necessários para melhor esclarecer estes resultados, delineando uma nova perspectiva na compreensão e abordagem destes pacientes

Sildenafil no tratamento da hipertensão pulmonar associada a lúpus eritematoso sistêmico e síndrome antifosfolipídio / Sildenafil for treatment of pulmonary hypertension in association with systemic lupus erythematosus and anti-phospholipid syndrome

Hipertensão pulmonar grave é uma doença debilitante, com expectativa de vida reduzida, que acomete adultos jovens. Complicações pleuropulmonares no lúpus eritematoso sistêmico ocorrem em 50 por cento a 70 por cento dos pacientes. A hipertensão pulmonar grave no lúpus eritematoso sistêmico é rara e tem prognóstico reservado. Descreve-se, pela primeira vez, um paciente com hipertensão pulmonar grave associada a lúpus eritematoso sistêmico e síndrome antifosfolipídio secundário que apresentou boa resposta ao uso do sildenafil oral, após falha do tratamento convencional com corticosteróides, ciclofosfamida, warfarin e diltiazem.
