Unhealthy habits and comorbidities associated with uncontrolled asthma in young people.

INTRODUCTION: Asthma is a chronic inflammatory disease of the lower airways that affects more than 260 million people worldwide and has been related to more than 460,000 deaths a year. It is estimated that in 60% of asthma cases, the symptoms are not adequately controlled. The objective of this study was to determine the association between some comorbidities, habits, and health risk behaviors with uncontrolled asthma in a sample of young people with asthma. METHODS: Through a cross-sectional study, data from 1,078 young people aged 17 to 19 years were analyzed. Information was collected through physical examination, direct questioning, and the application of a self-administered questionnaire. RESULTS: In the group of young people with asthma, the prevalence of uncontrolled asthma was 20.6%, of which 53.8% were women, 76.9% suffered from rhinitis, 46.2% were overweight and 23.1% were obese. In the group of young with uncontrolled asthma, gingivitis was detected in 53.8% and alcohol consumption in 84.6%. Logistic regression analysis showed a significant association between allergic rhinitis, gingivitis, carbohydrate intake, alcohol consumption, overweight, and obesity with uncontrolled asthma. CONCLUSIONS: Parents and members of the health team need to identify on time the risk factors associated with uncontrolled asthma in young people with asthma to limit its development and the negative effects it generates. The results of this study should be used to strengthen programs that promote the comprehensive health of adolescents.

Risk factors of non-adherence to guidelines for the prevention of COVID-19 among young adults with asthma in a region with a high risk of a COVID-19 outbreak.

OBJECTIVE: SARS-CoV-2 disease 2019 (COVID-19) is highly contagious and spreads rapidly. The application of preventive measures has proven to be the best strategy to minimize the number of patients and the dissemination of and deaths from COVID-19. The objective of this study was to determine the risk factors that limit the adherence of asthmatic patients to measures that prevent COVID-19 among residents of a region with a high risk of a COVID-19 outbreak. METHODS: Through a cross-sectional study, data from 2,372 participants aged 16-24 years were analyzed. To collect their information, a questionnaire was constructed using the Google Forms tool. Due to the prevention measures in place for COVID-19, the home quarantine of many people, and the lack of socialization, the questionnaire was distributed through email (Internet) and WhatsApp. A logistic regression analysis was performed to determine the relationship between the variables. RESULTS: The prevalence of asthma was 12.2%, and non-adherence to the guidelines for the prevention of COVID-19 was 53.1%. Approximately 30.8% of asthma patients did not comply with the basic prevention measures for COVID-19. The results of the logistic regression analysis showed that being male, active smoking, and believing that COVID-19 is not a more severe disease for people suffering from asthma than others were associated with non-adherence to the basic protection measures established in the guidelines for the prevention of COVID-19. CONCLUSIONS: It is important for health professionals to advise asthma patients to comply with the basic measures of protection against COVID-19 and timely use medications for asthma control.

Corneal blindness in Platos cave: the acting forces to prevent and revert corneal opacity. Part I: epidemiology and new physiopathological concepts / A cegueira corneal na caverna de Platão: as forças para prevenir e reverter a opacidade da córnea. Parte I: epidemiologia e novos conceitos na fisiopatologia

ABSTRACT The burden of corneal blindness and visual deficiency can be felt worldwide. Its association with several endemic diseases such as childhood blindness, trauma, infectious keratitis (including variants caused by herpes, hanseniasis, and fungi), vitamin A deficiency, diabetes mellitus, and other dry eye syndromes reflects its poorly understood underlying mechanisms and suggests that the actual frequency of the disease is underestimated. The low effectiveness of preventive and therapeutic strategies against corneal scarring or deformity predicts a high frequency of patients with corneal blindness in the future. Corneal blindness is associated with environmental factors and socioeconomic limitations that restrain health assistance and maintain a modest efficiency of the current therapeutic strategies for resolving corneal diseases in large-scale programs. We present here a critical review of the concepts associated with corneal blindness that need to be considered when planning strategies to prevent and treat corneal blindness worldwide (to be able to leave Plato's cave, where corneal blindness is encaged.

RESUMO O problema da deficiência visual e da cegueira corneal abrange o mundo todo e corresponde à quarta causa de cegueira e deficiência visual, com acometimento estimado de mais de 16 milhões de pessoas. A associação com várias doenças endêmicas, como cegueira infantil, trauma, ceratites infecciosas (incluindo herpes, hanseníase e fungos), hipovitaminose A, diabetes mellitus e outras causas de síndromes de olho seco, indicam que a verdadeira frequência é subestimada e que os diferentes mecanismos são pouco conhecidos. A baixa eficácia na prevenção e tratamento da cicatriz e deformidade da córnea permite antecipar que a prevalência da cegueira corneal irá crescer no futuro. As razões para o aumento da cegueira corneal envolvem fatores ambientais, limitações socioeconômicas para ampliar a assistência à saúde e a modesta eficiência das estratégias terapêuticas para resolver o problema em grande escala. O presente trabalho traz uma revisão crítica dos conceitos associados à cegueira corneal. Essa análise é uma etapa necessária para preparar o caminho com o objetivo de deixar a caverna que encarcera a cegueira corneal, em analogia ao mito de Platão, e melhorar as estratégias para prevenir e tratar a cegueira corneal em escala mundial.

La ocurrencia de rebrotes de la COVID-19 y su relación con el número reproductivo

RESUMEN El peligro de la ocurrencia de endemia por la COVID-19 es una preocupación del gobierno y epidemiólogos cubanos, pero conocer alguna métrica que influya en su surgimiento es de gran utilidad para evitarla. El objetivo de este trabajo es demostrar mediante modelos dinámicos y teoría cualitaiva de ecuaciones diferenciales, cómo el número reproductivo básico Ro constituye una métrica que incide en la ocurrencia de estos eventos. Se empleó un modelo de tipo SIR con demografía adaptado a las condiciones de Cuba. Los resultados demostraron que se consigue dar respuesta, desde el punto de vista matemático, a las condiciones que pueden causar un rebrote de la enfermedad. Recomendamos mantener activadas las medidas epidemiológicas que se relacionan en este trabajo y que ayudan a mantener controlados los casos confirmados que aparezcan y evitar de esta manera posibles rebrotes.

ABSTRACT The danger of the occurrence of endemic COVID-19 worries the Cuban government as well as epidemiologists. Knowledge about a metric that influences its emergence is a very useful tool to prevent it. The purpose of the study was to prove through dynamic models and the qualitative theory of differential equations that the basic reproduction number R0 is a metric influencing the occurrence of these events. A SIR model was used, which was adjusted to Cuban conditions. Results showed that a mathematical response may be provided to conditions potentially causing a fresh outbreak of the disease. We recommend to maintain activated the epidemiological measures referred to in the paper, which help keep under control the confirmed cases occurring, thus preventing possible fresh outbreaks.

Estudiar los factores asociados a la prevención de la transmisión vertical VIH y su relación con la tasa de infección en niños. Estudio retrospectivo, analítico, observacional de la consulta de seguimiento VIH/Sida del Hospital Universitario de Caracas, período 2005-2010. Revisión de historias y fichas médicas de exposición perinatal VIH. Análisis estadístico descriptivo, cálculo de OR con intervalos de confianza de 95%. 321 niños incluidos. El diagnóstico de las madres VIH fue: 41,7% período preconcepcional, 41,7% gestación, 10,3% puerperio y 6,2% posnatal. 83,9% de las madres que recibieron tratamiento antrirretroviral durante gestación. 83,5% inició antes de las 34 semanas. 60,7% (n=195) de los neonatos fueron obtenidos por cesárea. 49,1% (n=158) de las madres recibieron zidovudina intraparto. 72,6% (n=238) de los neonatos inició adecuadamente zidovudina. 9% (n=28) recibió lactancia materna. Tasa general de transmisión VIH 5,6% (n=18), con ascenso en la tasa desde 1,4% (IC:0,18-5,20) en las diagnosticadas durante período preconcepcional, hasta 50,0% (IC:25,58-74,41) en posnatal. El acumulado de factores de protección resulta en menor tasa de infección con el cumplimiento de al menos 2 de ellos (P<0,05). El cumplimiento del tratamiento gestacional materno, zidovudina periparto, cesárea electiva, zidovudina neonatal y omisión de leche materna fueron factores protectores estadísticamente significativos para la prevención de la transmisión vertical VIH. El control prenatal y el cumplimiento del tratamiento antirretroviral gestacional materno, zidovudinaperiparto, cesárea electiva, zidovudina neonatal y omisión de leche materna son factores protectores efectivos para disminuir la transmisión vertical. El programa nacional de tratamiento antirretroviral para infección VIH debe continuar y optimizar su funcionamiento

Study the factors associated with the prevention of HIV vertical transmission and the relation with the rate of infection in children. Retrospective, analytic and observational study of the Infectious Pediatrics Consultation at the Hospital Universitario de Caracas, during 2005 to 2010. Medical histories and data from the format of perinatal HIV exposition were revised. Descriptive analysis, OR calculation with confidence intervals of 95%. 321 children were included. The HIV diagnosis of mothers were: 41,7% in the preconceptional period, 41,7% in the gestational period, 10,3% in the puerperal period and 6,2% in the posnatal period. 83,9% of mothers who received antiretroviral treatment before birth. 72,6% (n=238) of the newborns used AZT, 9% received breastfeeding. Rate of HIV transmission was 5,6% (n=18). If diagnosis had been preconceptional, the rate was 1,4% (IC:0,18-5,20) and it increased to 50,0% (IC:25,58-74,41), in case of the posnatal diagnosis. The accomplishment of at least two protective factors resulted in a lower rate of infection (P<0,05). The gestational treatment, the AZT before birth, the elective cesarean, the AZT neonatal and the omission of breastfeeding were protective factors with statistical significance to prevent vertical transmission of HIV. The gestational treatment, the AZT before birth, the elective cesarean, the AZT neonatal and the omission of breastfeeding are protective factors effective to prevent HIV vertical transmission. The national program of antiretroviral treatment must be maintained and optimized

La caries dental y los factores relacionados en una población de adultos de la ciudad de la rioja, Argentina / The dental caries and related factors in adult population of the city of rioja, Argentina

La caries dental es un proceso patológico post-eruptivo, localizado, externo, involucra un reblandecimiento de los tejidos duros del diente procediendo a la formación de una cavidad1. Se determinó la presencia de caries dental, su relación con factores patológicos y preventivos en adultos de La Rioja, Argentina. A partir de 183 adultos de 25 a 35 años de edad se estudiaron los dientes con caries, obturaciones, perdidos e índice CPOD y se registraron en una ficha dental. Por cada adulto se obtuvo una historia clínica. El 77% de los adultos presentó un promedio de 3,73±4,28 caries, 4,75±4,61 obturaciones, 1,91±2,92 perdidos e índice CPOD 10,39±5,90. El CPOD para el género femenino fue mayor que para el masculino (p=0,042). La caries se relacionó con bajo nivel de educación (p=0,0001), ingreso económico (p=0,0086), cepillado dental diario (p=0,0340), cepillado nocturno (p=0,0018), con consulta prevalente por dolor (p<0,0001), falta de visita bucal anual (p=0,0003) y de obra social (p=0,0064). La caries dental es una enfermedad presente en la población adulta se asocia con bajo nivel de educación, económico y preventivo dental. Necesita del abordaje económico cultural integrado de la sociedad para mejorar la salud bucal del adulto y asegurar su calidad de vida en su senectud.

The dental caries is defined a post eruptive pathological process of external origin located tooth involves softening of the hard tissues of the tooth proceeding consequently to the formation of a tooth cavity1. The presence of dental caries was determined, its relationship with pathological and preventive factors in adults of La Rioja, Argentina. From 183 adults from 25-35 years of age, were studied decayed, fillings, missing teeth and index DMFT and recorded on a dental chart. For each adult, a clinic history was obtained. The 77% of adults had a mean of 3,73 ±4,28 caries, 4,75 ±4,61 filling, 1,91 ±2,92 missing and DMFT 10,39 ±5,90. The DMFT was higher for the female gender than for males (p=0,042). Caries was associated with low level of education (p=0,0001), low income (p=0,0086) lack tooth daily brushing (p<0,0340), lack of night brushing (p=0,018), check only for pain (p< 0,0001), lack of annual dental visit (p=0,0003) and absence of coverage social (p=0,0064). Dental caries is a disease present in the population of adults, is associated with low level education, economic and lack of prevention dental. Requires a socio cultural economic work of society to improve the oral health of adults and ensure their senescence.

Efeito do gel de clorexidina em diferentes concentrações no controle do biofilme bacteriano e da inflamação gengival em crianças / Effect of clorexidina in different concentrations in the control on dental plaque and inflammation gingival in children

O presente estudo teve como objetivo avaliar a efetividade da utilização de géis de clorexidina nas concentrações de 0,5%, 1% e 2% para o controle do biofilme dentário e da inflamação gengival em crianças na faixa etária de 7 a 11 anos de idade. A amostra foi composta por 40 crianças, aleatoriamente divididas em quatro grupos: G1 (grupo controle - não utilização de agente químico), G2 (utilização de gel de clorexidina a 0,5%), G3 (utilização de gel de clorexidina a 1%) e G4 (utilização de gel de clorexidina a 2%) para determinação dos índices de placa e gengival. O gel de clorexidina foi aplicado com a utilização de moldeiras descartáveis pré-fabricadas (5 mL), por 1 minuto, uma vez por semana, durante 4 semanas. As avaliações clínicas foram feitas após 1 semana, 1 mês, 3 e 6 meses da última aplicação do gel. Os resultados obtidos foram analisados pela análise de variância a dois critérios, sendo adotado nível de significância igual a 5%. Os índices de placa e gengival reduziram durante o período experimental em todos os grupos. Não houve diferença significante (p <0.05) entre os grupos tratados com gel de clorexidina quando comparado com o grupo placebo na redução de placa e índice gengival. Os resultados mostraram que formulações diferentes de gel de clorexidina não produzem efeito inibidor da placa bacteriana e da inflamação gengival. Sendo assim, estudos adicionais são necessários para esclarecer o papel da clorexidina na prevenção de cárie e doença periodontal em crianças.

The purpose of the present study was to assess the effect of three different formulations of chlorhexidine gel in the concentrations of 0.2%, 1% and 2% for the control of plaque accumulation and gingivitis. This was a double-blind, longitudinal, non-crossover study in 48 children between 7 to 11 years of age. Subjects were randomly assigned to 4 different groups: G 1 (placebo), G 2 (0.2% chlorhexidine gel), G 3 (1% chlorhexidine gel) and G 4 (2% chlorhexidine gel). The chlorhexidine gel was administered once a week during 4 weeks. The clinical evaluations were made after 1 week, 1, 3 and 6 months of the last application of the chlorhexidine gel. Mean plaque and gingival scores were reduced over the four-week trial period for experimental and control groups. There was no significant difference (p<0.05) between the groups treated with chlorhexidine gel when compared with the placebo group in the reduction of plaque and gingival scores. The results indicated that different formulations of chlorhexidine gel did not produce an effective inhibitor of plaque growth. Within the limitations of the present study design, further studies are required to clarify the role of chlorhexidine to prevent caries and periodontal disease.
