Secondary osteoporosis and respiratory diseases: An update / 中华内分泌代谢杂志

Long-term burden of illness and associated medication usage make osteoporosis(OP) a common complication of respiratory diseases. The pathogenic risk factors and treatment strategies for respiratory diseases related OP are similar to primary OP. However, due to differences in the pathogenesis of each disease, there are distinctions in the characteristics of bone loss and treatment approaches. Therefore, targeted diagnostic and therapeutic plans need to be formulated. This article provides a comprehensive review of secondary OP caused by common respiratory diseases in terms of epidemiological characteristics, related risk factors or possible mechanisms, changes in bone metabolic indexes or characteristics of bone damage, and progress in diagnosis and treatment. The aim of this review is to offer insights into the prevention and treatment of secondary OP related to respiratory diseases and promote the development of a multidisciplinary collaborative approach.

Prevalence of Chronic Non-Communicable Respiratory Diseases in Mosul City

@#Introduction: Chronic non-communicable respiratory diseases (CNCRDs) encompass a group of conditions affecting the airways and lung structures, including Chronic Obstructive Pulmonary Disease (COPD), emphysema, allergic rhinitis, asthma, pulmonary arterial hypertension, and cystic fibrosis. CNCRDs pose a significant global health challenge, resulting in approximately four million deaths annually. This study aimed to identify the prevalence and risk factors associated with CNCRDs and measure trends in the prevalence of these risk factors over time. Methods: A cross-sectional epidemiological study was conducted using data collected from primary health centers on both sides of Mosul City. The study period extended from January 1 to July 31, 2022, with information obtained from (40) primary health centers, consisting of (20) centers on the right side and (20) centers on the left side of Mosul. Results: In 2021, the City of Mosul recorded a total of 13,005 registered cases, with 5,598 cases being attributed to asthma (43%), and 7,347 cases being associated with COPD (57%). Bronchial asthma constituted 43% of cases, with 5598 patients, and the highest incidence occurred in the age group between 20-44 years. Conclusion: The prevalence of bronchial asthma and COPD among patients with CNCRDs in Mosul is alarmingly high. It emphasizes the importance of implementing preventive policies and strategies targeting modifiable risk factors for these respiratory conditions.

Consideration points in the decision making in chronic respiratory diseases / Journal of Rural Medicine

Objective: Even though dynamic multidisciplinary team discussions are crucial for end-of-life care management and decisions concerning chronic obstructive pulmonary disease (COPD), the details of the discussion contents remain poorly understood. This study aimed to identify essential considerations in decision-making for patients with chronic respiratory diseases to enhance a consensus-based approach.Materials and Methods: A qualitative content analysis of focus group conversations on published clinical case reports in the Japanese community about end-of-life care for patients with chronic respiratory disorders was conducted. The cases were searched through Igaku Chuo Zasshi (ICHUSHI) and Google in February 2021, using the keywords: “COPD”, “chronic respiratory diseases”, and “end-of-life care”. A total of 41 healthcare professionals participated in the focus group discussions.Results: Four major themes evolved from the qualitative content analysis: unpredictable disease prognosis and stages, low awareness of patients on disease severity, acute exacerbations, and home oxygen therapy (HOT). The participants perceived that assessment of severity and prognosis in chronic respiratory diseases such as COPD was a core discussion point to enhance patients’ decision-making. The study’s findings also indicated that healthcare providers evaluate the influence of acute aggravation of the condition on patients’ perceived health status and decision-making.Conclusion: The study reaffirms the significance of informed consent in patients with chronic respiratory disease. It details how, after a thorough assessment of disease severity, patients are given personalized explanations of standardized HOT. This approach ensures they fully understand the unpredictable nature and various stages of their condition resulting from acute exacerbations.

Complement lectins and respiratory diseases / 中国免疫学杂志

The complement lectin pathway is an important means to exert immune effect.Ficolin and Mannan-binding lectin(MBL)are the initiators of complement pathway.Both structure and function are very similar.They can activate the complement path-way by recognizing certain substances on the surface of pathogens,emphasizing phagocytosis or directly kill and dissolve related patho-gens,thereby playing an important role in the immune system,especially in fighting infection.The respiratory system diseases are mostly infectious diseases.In recent years,there have been reports that ficolin/MBL is related to many other respiratory diseases.This article discusses the related research of ficolin/MBL and respiratory diseases,hopes to provide theoretical support for related research.

Risk factors and determinants of pulmonary function impairments in chronic respiratory diseases in Ethiopia: A hospital-based cross-sectional study

Introduction: Chronic respiratory diseases (CRDs) are diseases of the lung airways and parenchyma. Globally, they are the leading causes of morbidity and mortality. This study aimed to characterize the common CRDs, along with their lung function and possible determinants in symptomatic patients attending Bishoftu General Hospital, Ethiopia. Methods: A cross-sessional study was conducted at the outpatient of Bishoftu Hospital, Ethiopia from June 2019 to March 2020. Consecutive adult patients aged 18 and above with CRDs (≥8 weeks) were recruited. Questionnaires were used to collect data on demographics, symptoms, diagnoses, and putative risk factors. Lung function was measured by spirometry. Result: A total of 170 participants were recruited, the majority 102(60.0%) were female. The mean age was 49 years (SD=16). The most common symptoms were wheezing in the last twelve months 156 (91.8%), cough 138 (81.2%), and severe exertional breathlessness 137 (80.6%). Thirty-nine (22.9%) were either active or passive smokers. Half of the patients (50.3%) were exposed daily to vapors, dust, gases, or fumes and 58 (34.3%) were exposed to biomass smoke. In total, 138 (81.2%) had a positive allergen skin prick test. Chronic bronchitis (49.1%) and asthma (36.1%) were the most common clinical diagnoses. Classification of lung function revealed 23 (15%) normal, 29 (19%) obstructive, 36(23.5%) restrictive and 61(39.9%) mixed patterns. Airflow obstruction was independently associated with increasing age (p<0.05), exertional breathlessness (p<0.001), previous history of asthma (p<0.05), BMI (p<0.05), and doctor-diagnosed chronic obstructive pulmonary disease (p<0.001) and asthma (p<0.05). Conclusion: This study shows a high burden of abnormal lung function in patients attending clinics because of CRDs symptoms. These findings support the critical need for spirometry services to determine lung abnormality in patients with chronic respiratory symptoms.

Enfermedades respiratorias en México. Análisis del estudio Global Burden of Disease 2021 / Respiratory diseases in Mexico. Analysis from the Global Burden of Disease study 2021

Resumen Antecedentes: Las enfermedades respiratorias (ER) se analizan individualmente, posiblemente con subestimación de su carga total. Objetivo: Analizar la carga de las ER en México para población de 20 años o más de 1990 a 2021. Material y métodos: Se presenta la carga de ER en México a partir de estimaciones del estudio Global Burden of Disease en cuanto a mortalidad y años de vida saludable (AVISA) perdidos que comprenden recuentos, tasas por 100 000 y tasas estandarizadas por edad. Las ER se categorizaron en enfermedades respiratorias crónicas (ERC), infecciones respiratorias y cánceres respiratorios. Resultados: En 2021, las ER causaron la muerte de 336 728 adultos mayores de 20 años, lo que representó 30.5 % del total de defunciones, incremento cercano al triple respecto a 2019, principalmente debido a COVID-19. Las ERC contribuyeron con 3.4 % del total de muertes, las infecciones respiratorias con 25.9 % y los cánceres respiratorios con 1.2 %. La mortalidad y AVISA perdidos por ERC se incrementaron persistentemente, con variaciones entre los estados. Las tasas de mortalidad ajustadas por edad de las ERC disminuyeron desde 1990, excepto las enfermedades pulmonares intersticiales, que se incrementaron constantemente. Conclusión: Los significativos niveles de mortalidad y discapacidad debidos a enfermedades respiratorias en México exigen mejorar la prevención, investigación y abordar factores de riesgo como tabaquismo y contaminación, además de fomentar la capacitación médica continua.

Abstract Background: Respiratory diseases (RD) are often analyzed separately rather, possibly leading to an underestimation of their total burden. Objective: To analyze the burden of RD in Mexico for population aged 20 or older from 1990 to 2021. Material y methods: We present the burden of RD in Mexico based on estimates of the Global Burden of Disease study for mortality and disability-adjusted life years (DALYs), comprising counts, rates per 100,000, as well as age-standardized rates. RDs were categorized into three key groups: chronic respiratory diseases (CRD), respiratory infections (RI), and respiratory cancers. Results: In 2021, among those aged 20+, RDs were responsible for 336,728 deaths, which accounts for 30.5% of total deaths— a nearly threefold increase since 2019, primarily due to the COVID-19 pandemic. CRDs contributed with 3.4% of total deaths; RIs, with 25.9%; and respiratory cancers, with 1.2%. CRDs showed a continuous rise in deaths, crude mortality, and DALY rates across genders, with no signs of leveling. RD burden varied widely across states. Age-standardized CRD mortality rates have generally declined since 1990, except for interstitial lung diseases, which have consistently increased. Conclusion: The significant burden of mortality and disability due to RDs in Mexico underscores the necessity for enhanced prevention, research, and for addressing risk factors such as smoking and pollution. Ongoing healthcare training can help reduce RD burden.

Relación de las Enfermedades Crónicas no Transmisibles y Ejercicio Físico en la Población Chilena entre los años 2015-2016 / Risk of Retention of Secretions in Patients with Invasive Mechanical Ventilation

Introducción. Las prevalencias de la inactividad física, el sedentarismo y el sobrepeso y obesidad han aumentado sus índices durante los últimos años en Chile, lo que conlleva al desarrollo y aparición de diversas enfermedades crónicas no transmisibles, como por ejemplo, hipertensión arterial, diabetes mellitus e inclusive enfermedades respiratorias, las cuales repercuten negativamente en la población y deterioran la calidad de vida de las personas, independientemente el sexo y el rango etario. El ejercicio físico es una de las principales herramientas utilizadas por diversos profesionales de la salud como método de prevención y tratamiento en la población afectada, inclusive representa una alternativa de menor costo. Objetivo. Relacionar el ejercicio físico de alta y mediana intensidad con las enfermedades crónicas no transmisibles en personas mayores a 18 años residentes en Chile durante el periodo 2015-2016. Métodos. Análisis cuantitativo, descriptivo, transversal y retrospectivo de base secundaria ENCAVI 2015-2016, de residentes en Chile mayores de 18 años y con al menos una de las siguientes condiciones de salud: Hipertensión arterial, Diabetes Mellitus y enfermedades respiratorias crónicas no transmisibles. Resultados. Todas las variables presentan relaciones significativas (p<0,005) (HTA, DM, enfermedades respiratorias, edad, horas sentado, ejercicio físico de moderada y alta intensidad. Sin embargo, las variables de ejercicio físico moderada intensidad y enfermedades respiratorias (p=0,578) y las variables de sexo y horas sentado (p=0,005) no presentan relación significativa. Discusión. El ejercicio físico de moderada intensidad es el que tiene mejor respuesta ante las diferentes patologías según diferentes autores, por otro lado, en la recopilación de datos podemos encontrar que este tipo de ejercicio es efectivo en la Diabetes Mellitus. Conclusiones. Según los datos analizados, mientras mayor frecuencia de ejercicio físico de alta intensidad (en días) y ejercicio físico de moderada intensidad (en horas) se realice durante los últimos días de la semana, los diagnósticos de las enfermedades crónicas no transmisibles (HTA, DM) y enfermedades respiratorias se verán controladas, mientras que, cuando existe menor frecuencia del ejercicio físico realizado durante los últimos días de la semana, tiende a existir mayor diagnóstico.

Background. The prevalence of physical inactivity, sedentary lifestyle, and overweight and obesity have increased their rates in recent years in Chile, which leads to the development and appearance of various chronic non-communicable diseases, such as for example, arterial hypertension, diabetes mellitus and even respiratory diseases, which have a negative impact on the population and deteriorate the quality of life of people, regardless of gender and age range (7). Physical exercise is one of the main tools used by various health professionals as a method of prevention and treatment in the affected population, even representing a lower cost alternative. Objetive. To relate high and medium intensity physical exercise with chronic non-communicable diseases in people over 18 years of age residing in Chile during the period 2015-2016. Methods. Quantitative, descriptive, cross-sectional and retrospective analysis of the ENCAVI 2015-2016 secondary base of residents in Chile over 18 years of age and with at least one of the following health conditions: High blood pressure, Diabetes Mellitus and chronic non-communicable respiratory diseases. Results. All the variables present significant relationships (p<0.005) (HTN, DM, respiratory diseases, age, hours sitting, moderate and high intensity physical exercise. However, the variables of moderate intensity physical exercise and respiratory diseases (p=0.578) and the variables of sex and sitting hours (p=0.005) do not present a significant relationship. Discussion. Moderate intensity physical exercise is the one that has the best response to different pathologies according to different authors, on the other hand, in data collection we can found that this type of exercise is effective in Diabetes Mellitus. Conclusions. According to the data analyzed, the greater the frequency of high-intensity physical exercise (in days) and moderate-intensity physical exercise (in hours) performed during the last days of the week, the diagnoses of chronic non-communicable diseases (HTN, DM) and respiratory diseases will be controlled, while, when there is less frequency of physical exercise carried out during the last days of the week, there tends to be a greater diagnosis.

Programa de salud y enfoque sociocultural en comunidades rurales de Ancash, Perú

Introducción: En intervenciones con tecnologías apropiadas, orientadas a mejorar la salud respiratoria, predomina el precepto de que en comunidades rurales, su sola aplicación resuelve los problemas de salud. Aun cuando la educación socio-cultural ha adquirido una alta prioridad, sigue ocupando una importancia menor. Objetivo: Comprender cómo las particularidades y las semejanzas de los programas de salud con tecnología apropiada, de ayer y de hoy, impactan en la calidad de vida de las mujeres rurales. Métodos: Se realizó un estudio con diseño cualitativo. En un primer momento, en tres grupos de La Esperanza, se evaluaron tres propuestas: Grupo 1 (Cocina Mejorada-Programa Educativo), Grupo 2 (Cocina Mejorada) y Grupo 3 (Programa Educativo). Cada grupo estuvo conformado por 15 mujeres. La información se obtuvo a partir de los cambios observados y las notas de campo. En un segundo momento, se analizaron las percepciones sobre cocinas mejoradas recientemente implementadas, a través de la realización de entrevistas a tres mujeres residentes en Chamana. Resultados: En La Esperanza, el grupo 1 alcanzó cambios ostensibles en todas las variables. El grupo 2 mantuvo prácticas inadecuadas. El grupo 3 logró cambios en las variables no vinculadas con la tecnología apropiada. En Chamana, debido a una capacitación insuficiente, las mujeres no reconocen las buenas prácticas para el uso de las cocinas mejoradas ni su impacto en la salud. Conclusiones: Una implementación con cocina mejorada acompañada con un pertinente programa educativo resulta cualitativamente superior. La presunción de que las tecnologías apropiadas por sí solas, podrían generar los cambios deseados, es cuestionable a todas luces.

Introduction: In interventions with appropriate technologies, aimed at improving respiratory health, the precept that in rural communities their application alone solves health problems predominates. Although socio-cultural education has acquired a high priority, it is still of lesser importance. Objective: To understand how the particularities and similarities of health programs with past and present appropriate technology impact the quality of life of rural women. Methods: A qualitative study was conducted. Initially, three proposals were evaluated in three groups of La Esperanza: Group 1 (Improved Cooking-Educational Program), Group 2 (Improved Cooking) and Group 3 (Educational Program). Each group consisted of 15 women. Information was obtained from observed changes and field notes. In a second moment, perceptions about recently implemented improved cookstoves were analyzed, through interviews with three women living in Chamana. Results: In La Esperanza, group 1 achieved significant changes in all variables. Group 2 maintained inadequate practices. Group 3 achieved changes in variables not linked to appropriate technology. In Chamana, due to insufficient training, women do not recognize good practices for the use of improved cookstoves and their impact on health. Conclusions: An implementation with improved cooking accompanied by a relevant educational program is qualitatively superior. The presumption that appropriate technologies alone could bring about the desired changes is clearly questionable.

SARS-CoV-2 induced changes in the lungs based on autopsy cases

Context: Researchers throughout the world devote enormous efforts to reveal the peculiarities of the pathogenesis of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, however, it continues to surprise and cause the death of millions of people. Aims: This article aims to study the molecular mechanisms provoked by SARS-CoV-2, the virus-induced changes in Angiotensin-converting enzyme 2 (ACE2) functionality, in the vascular homeostasis through CD34 expression, B-cell immunity through the expression of CD20 and CD79?, and adhesion molecules through E-cadherin. Settings and Design: This was a prospective, descriptive, and observational study. Methods and Material: A total of 15 autopsies of patients deceased by COVID-19 infection, confirmed by PCR, were performed. The lungs of all patients were examined histologically and immunohistochemically for ACE2, E-cadherin, CD34, CD20, and CD79?. Results: Immunohistological analysis showed increased ACE2 expression in all lung autopsy material affected by COVID-19 infection and we found a higher intensity of ACE2 expression than that of a healthy lung. CD20 examination reveals total deficiency of B-cells in the pulmonary parenchyma and CD79? is also absent. E-Cadherin is not expressed in the basal cellular sections where the contact elements are missing. CD34 demonstrates a desquamation of the endothelial cells, which indicates a direct damage of the vascular walls. Conclusions: We found that patients who died after severe COVID-19 had high immune deficiency and impaired intercellular communication in the parenchyma and endothelium of lung tissue, leading to severe thromboembolic complications in patients with multiple diseases.

Introduction. Particulate matter (PM) is one of the air pollutants most involved in the onset or exacerbation of respiratory conditions in children. Objective. To describe the characteristics of consultations for acute respiratory diseases in children younger than 15 years and the levels of PM in the air and to analyze their association in a sector of Bahía Blanca between April 2019 and March 2020. Population and methods. Ecological, time-series study with multiple groups. Descriptive analysis of total number of consultations, by area, diagnosis, and PM. Generalized linear correlation and regression model to determine the relationship among variables. The SPSS® software was used. Results. Data from 4787 consultations were collected. Of these, 38.6% (1846) were related to rhinitis and 21.1% (1011), to bronchospasm. PM of 10 nm (PM10) exceeded its limit value on 31% (115) of the study days, and PM of 2.5 nm (PM2.5), on 3% (8). A 10% increase in PM2.5 showed increases of 1.3% in total consultations; the increase reached 2.1% in the area closest to the industrial sector (p < 0.05). In the latter, a 10% increase in PM10 was associated with an increase of 1.8% in consultations (p < 0.05). Conclusion. A positive association was evidenced between consultations for acute respiratory diseases and PM levels in the air, especially with PM2.5 and in the area closest to the industrial sector.

Probability of premature mortality due to four chronic diseases in Jiangmen City from 2012 to 2021 / 预防医学

Objective@#To investigate the mortality of malignant tumors, diabetes, cardio-cerebrovascular diseases and chronic respiratory diseases and trends in probability of premature mortality due to these four chronic diseases in Jiangmen City, Guangdong Province from 2012 to 2021, so as to provide the evidence for perfecting the chronic disease control strategy. @*Methods@#The mortality of malignant tumors, diabetes, cardio-cerebrovascular diseases and chronic respiratory diseases among household registered residents in Jiangmen City from 2012 to 2021 were collected from the Guangdong Provincial Population Death Information Registration Management System, and the crude mortality, standardized mortality by the population of the Fifth National Population Census in China in 2000 and probability of premature mortality were calculated. The trends in mortality and probability of premature mortality were analyzed using average annual percent change (AAPC), and whether achieving the targets for the probability of premature mortality due to four chronic diseases in 2025 and 2030 were evaluated.@*Results@#A total of 226 012 deaths occurred due to four chronic diseases in Jiangmen City from 2012 to 2021, and the overall crude mortality and standardized mortality rates were 569.22/105 and 283.29/105, with a reduction in the probability of premature mortality from 15.04% to 12.05% (AAPC=-2.403%, Z=-7.603, P<0.001). The probability of premature mortality due to four chronic diseases decreased from 19.21% to 16.38% in males, and from 10.42% to 7.58% in females (AAPC=-1.893% and -3.085%, Z=-5.262 and -9.811, both P<0.001). The probability of premature mortality due to diabetes appeared a tendency towards a rise (AAPC=2.317%, Z=2.548, P=0.034), and the probability of premature mortality due to cardio-cerebrovascular diseases showed a tendency towards a decline (AAPC=-4.826%, Z=-13.590, P<0.001), while no significant changing trend was seen in the probability of premature mortality due to malignant tumors or chronic respiratory diseases (AAPC=-0.751% and -2.461%, Z=-1.532 and -1.730, P=0.125 and 0.122). The predicted probability of premature mortality due to four chronic diseases was 10.92% in 2025 and 9.66% in 2030 in Jiangmen City, which were both lower than the target (11.21% and 9.81%). @*Conclusions@#The probability of premature mortality due to four chronic diseases appeared a tendency towards a decline in Jiangmen City from 2012 to 2021, which can reach the target in 2025 and 2030. Males should be given a high priority for interventions of chronic diseases, and diabetes control should be reinforced.

Clinical Evidence of Chinese Patent Medicines in Treatment of Respiratory Diseases in Children： A Scoping Review / 中国实验方剂学杂志

ObjectiveThis study performed a scoping review to comprehensively analyze and report the information on the instructions of Chinese patent medicines and clinical research evidence for the treatment of respiratory diseases in children. MethodChinese patent medicines against respiratory diseases in children were obtained by searching the three major drug catalogues. The Chinese and English databases were searched for relevant literature，followed by data statistics and visualized analysis. ResultAfter screening and analysis，52 Chinese patent medicines were included，involving nine dosage forms. The main drugs were Scutellariae Radix，Armeniacae Semen Amarum，Forsythiae Fructus，etc. The main functions included clearing heat and releasing exterior syndrome，and relieving cough and dissipating phlegm. The indications mainly included common cold with wind-heat syndrome and cough in children. Adverse drug reactions and contraindications were only specified in 19.23% （10/52） of Chinese patent medicines，and the rest only displayed "unclear". A total of 279 articles were included，including 277 articles from Chinese Core Periodicals and two articles from SCIE. In terms of research type，those articles included 253 randomized controlled trials （RCTs，with six dosage form/dose comparisons involved），11 retrospective analyses based on Hospital Information System （HIS） data，one case series，13 systematic reviews/Meta-analyses （with two network Meta-analyses involved），and one economic evaluation article. Among them，72.76% （203/279） of the articles were published in the Core Journals of Chinese Science and Technology. Only 33 Chinese patent medicines were involved，and Xiaoer Feire Kechuan Oral Liquid was the top 1 under investigation，accounting for 15.71% （44/280）. The indicated diseases were mainly infantile pneumonia，bronchitis，respiratory tract infection，cough，asthma，and other western medicine diseases. Xiaoer Chiqiao Qingre Granules and Xiaoer Dingchuan Oral Liquid were used off-label. The sample size was concentrated in 51-150 cases，accounting for 67.17% （178/265）. The interventions in the experimental group were mainly Chinese patent medicine + western medicine + basic treatment or Chinese patent medicine + western medicine. The main outcomes were the effective rate and the improvement of clinical symptoms. The adverse reactions were mainly gastrointestinal reactions，drug-induced skin symptoms，etc.，and two studies have shown that drug doses were associated with adverse reactions. ConclusionIn research years，the research on Chinese patent medicines in the treatment of respiratory diseases in children has advanced rapidly. However，there are still some problems that need to be resolved in the future，such as incomplete information on drug content in the instruction，concentrated drugs to be studied，limited indications，failure to highlight the characteristics of traditional Chinese medicine （TCM） syndromes，unstandardized research design，and an incomplete reflection of Chinese patent medicine.

Correlation between atmospheric nitrogen oxides and nitrogen dioxide acute exposure and outpatient visits of pediatric respiratory diseases / 预防医学

Objective @#To examine the association between acute exposure to traffic-related air pollutants (TRAP) NOX and NO2 and outpatient visits of pediatric respiratory diseases. @*Methods @#Data regarding outpatient visits to Department of Respiratory Diseases of Beijing Children's Hospital from 2015 to 2020 were collected, and the concentrations of nitrogen oxides (NOX), nitrogen dioxide (NO2) and other TRAP were collected from the surveillance sites assigned by the Peking University Health Science Center. A time-stratified case-crossover design was employed, and a conditional logistic regression model was created to examine the association between NOX and NO2 acute exposure and outpatient visits of pediatric respiratory diseases. @*Results @#The daily mean outpatient visits of pediatric respiratory diseases were 571 (interquartile range, 554) person-times among children at ages of 0 to 14 years in Beijing Children's Hospital from 2015 to 2020, and the daily mean outpatient visits for upper respiratory tract infections (URI), bronchitis, and pneumonia were 265 (interquartile range, 282), 143 (interquartile range, 178) and 128 (interquartile range, 120) person-times, respectively. The daily mean concentrations of atmospheric NOX and NO2 were 67.8 (interquartile range, 50.7) and 49.3 (interquartile range, 30.7) μg/m3, respectively. Conditional logistic regression analysis showed the largest lagged effect of NOX and NO2 on pediatric respiratory diseases at cumulative lags of 0 to 7 days. An increase in NOX concentrations by an interquartile range resulted in the excess risks of URI, bronchitis and pneumonia by 6.87% (95%CI: 6.37%-7.38%), 7.25% (95%CI: 6.51%-7.99%), and 5.51% (95%CI: 4.69%-6.33%), and an increase in NO2 concentrations by an interquartile range resulted in excess risks of URI, bronchitis and pneumonia by 5.71% (95%CI: 5.12%-6.31%), 5.32% (95%CI: 4.51%-6.14%), and 4.83% (95%CI: 3.91%-5.75%), respectively. NOX and NO2 presented a more remarkable effect on outpatient visits of pediatric respiratory diseases among children at ages of over 5 years. @*Conclusion @#NOx and NO2 acute exposure may increase the outpatient visits of pediatric respiratory diseases.

A Síndrome Respiratória Aguda Grave na pessoa idosa no contexto da pandemia da covid-19 e seus fatores associados / Severe Acute Respiratory Syndrome in older adults amid the COVID-19 pandemic and associated factors

Resumo A Síndrome Respiratória Aguda Grave (SRAG) constitui-se como uma das doenças respiratórias mais preocupantes, sendo caracterizada por um quadro gripal associado à taquipneia ou à hipoxemia e saturação inferior a 95% em ar ambiente. No contexto da pandemia do novo coronavírus (SARS-CoV-2) observou-se um crescimento exponencial nos casos sendo a pessoa idosa o grupo populacional mais afetado. Diante do exposto, este estudo teve como objetivo descrever os casos de SRAG, assim como os fatores sociodemográficos e de saúde associados ao óbito na população idosa de um município do norte do estado do Rio Grande do Sul, Brasil. Trata-se de um estudo epidemiológico, realizado a partir da análise de dados do Sistema de Informação de Vigilância Epidemiológica da Gripe. As informações foram disponibilizadas pela Secretaria Municipal de Saúde do município de Passo Fundo entre 01 de janeiro a 31 de dezembro de 2020. A estatística descritiva compreendeu a distribuição das frequências absolutas (n) e relativas (%) das variáveis de interesse. Na análise dos fatores associados estimouse razões de odds brutas e ajustadas por meio da Regressão Logística. Foi observado um total de 1.268 notificações por SRAG em idosos, sendo 72% causadas pela covid-19. A letalidade observada foi alta (40,9%), principalmente entre homens e de baixa escolaridade, sendo a presença de algum fator de risco determinante para o óbito, destacando-se a doença renal crônica. Espera-se que as associações evidenciadas neste trabalho possam auxiliar nas políticas de saúde direcionadas à saúde da pessoa idosa, sobretudo pelo fortalecimento das ações na rede de atenção primária.

Abstract Severe Acute Respiratory Syndrome (SARS) is one of the most worrying respiratory diseases, characterized by a flu-like condition associated with tachypnea or hypoxemia, with saturation below 95% in ambient air. In the context of the new coronavirus (SARSCoV- 2) pandemic, exponential growth in cases was observed, with the elderly being the most affected population group. This study aimed to describe SARS cases, as well as socio-demographic and health-associated factors in the elderly population of a city in the north of Rio Grande do Sul state, Brazil. This is an epidemiological study carried out by Influenza Epidemiological Surveillance Information System. The information was made available by the Municipal Health Department of the Passo Fundo between January 1st and December 31st, 2020. In the descriptive analysis, the distribution of absolute (n) and relative (%) frequencies of the variables of interest was performed. Crude and adjusted odds ratios were estimated using Logistic Regression. A total of 1,268 SARS notifications were observed in the elderly, 72% of which were caused by covid-19. The lethality was high (40.9%), mainly among men and those with low education, with the presence of at least one risk factor, especially chronic kidney disease. It is expected that the associations highlighted in this study can help to develop health policies aimed at the health of the elderly, especially by strengthening actions in primary health care.
