Effects of COVID-19-targeted non-pharmaceutical interventions on pediatric hospital admissions in North Italian hospitals, 2017 to 2022: a quasi-experimental study interrupted time-series analysis.

Background: The use of Non-Pharmaceutical Interventions (NPIs), such as lockdowns, social distancing and school closures, against the COVID-19 epidemic is debated, particularly for the possible negative effects on vulnerable populations, including children and adolescents. This study therefore aimed to quantify the impact of NPIs on the trend of pediatric hospitalizations during 2 years of pandemic compared to the previous 3 years, also considering two pandemic phases according to the type of adopted NPIs. Methods: This is a multicenter, quasi-experimental before-after study conducted in 12 hospitals of the Emilia-Romagna Region, Northern Italy, with NPI implementation as the intervention event. The 3 years preceding the beginning of NPI implementation (in March 2020) constituted the pre-pandemic phase. The subsequent 2 years were further subdivided into a school closure phase (up to September 2020) and a subsequent mitigation measures phase with less stringent restrictions. School closure was chosen as delimitation as it particularly concerns young people. Interrupted Time Series (ITS) regression analysis was applied to calculate Hospitalization Rate Ratios (HRR) on the diagnostic categories exhibiting the greatest variation. ITS allows the estimation of changes attributable to an intervention, both in terms of immediate (level change) and sustained (slope change) effects, while accounting for pre-intervention secular trends. Results: Overall, in the 60 months of the study there were 84,368 cases. Compared to the pre-pandemic years, statistically significant 35 and 19% decreases in hospitalizations were observed during school closure and in the following mitigation measures phase, respectively. The greatest reduction was recorded for "Respiratory Diseases," whereas the "Mental Disorders" category exhibited a significant increase during mitigation measures. ITS analysis confirms a high reduction of level change during school closure for Respiratory Diseases (HRR 0.19, 95%CI 0.08-0.47) and a similar but smaller significant reduction when mitigation measures were enacted. Level change for Mental Disorders significantly decreased during school closure (HRR 0.50, 95%CI 0.30-0.82) but increased during mitigation measures by 28% (HRR 1.28, 95%CI 0.98-1.69). Conclusion: Our findings provide information on the impact of COVID-19 NPIs which may inform public health policies in future health crises, plan effective control and preventative interventions and target resources where needed.

Impact of the COVID-19 pandemic in mortality due to respiratory diseases: A comparative analysis of 2021 and 2020 vs 2019 in Spain / Impacto de la pandemia de COVID-19 en la mortalidad por enfermedades respiratorias: análisis comparativo de 2021 y 2020 frente a 2019 en España

Introduction We previously reported an increase in respiratory mortality in 2020 in Spain after COVID-19. It is unclear if this rise is sustained in the longer-term. We aimed to determine whether respiratory mortality in 2021 in Spain returned to pre-pandemic levels. Material and methods In an observational, large study using official National Institute of Statistics data, we explored deaths due to respiratory diseases, that is, all causes of death by the standard WHO list of diseases of the respiratory system plus COVID-19, tuberculosis and lung cancer. Using the latest available official data of Spain, we analyzed changes in the mortality pattern in Spain from January 2019 to December 2021. We endorsed STROBE guidance for observational research. Results There were 98,714 deaths due to respiratory diseases in 2021 in Spain, corresponding to 21.9% of all deaths, becoming second in the ranking of causes of death. Respiratory diseases mortality in Spain has not returned to pre-pandemic levels in 2021, still with an increase of 30.3% (95% CI 30.2–30.4) compared to rates in 2019. All respiratory-specific causes of death decreased in 2021, except for lung cancer, that increased in women and decreased in men compared to 2019 (both p<0.05). In a multivariate analysis some established risk factors for respiratory diseases mortality were confirmed, such as male gender and older age; further, an association with reduced mortality in rural Spain was observed, still with a large geographical variability. Conclusions The COVID-19 pandemic has had a lasting impact on deaths due to respiratory diseases and certain specific causes of death in 2021, and it has disproportionately affected certain regions (AU)

Introducción Previamente informamos de un aumento de la mortalidad respiratoria en 2020 en España tras la COVID-19. No está claro si este aumento se mantiene a largo plazo. Nuestro objetivo fue determinar si la mortalidad respiratoria en 2021 en España volvió a los niveles previos a la pandemia. Métodos En un gran estudio observacional con datos oficiales del Instituto Nacional de Estadística exploramos las muertes por enfermedades respiratorias, es decir, todas las causas de muerte según la lista estándar de enfermedades del sistema respiratorio de la Organización Mundial de la Salud más COVID-19, tuberculosis y cáncer de pulmón. Utilizando los últimos datos oficiales disponibles de España analizamos los cambios en el patrón de mortalidad en España desde enero de 2019 hasta diciembre de 2021. Seguimos la guía STROBE para investigación observacional. Resultados Se produjeron 98.714 muertes por enfermedades respiratorias en 2021 en España, lo que corresponde a 21,9% del total de muertes, situándose en el segundo lugar del ranking de causas de muerte. La mortalidad por enfermedades respiratorias en España no ha vuelto a los niveles previos a la pandemia en 2021, aun con un aumento de 30,3% (IC 95% 30,2-30,4) respecto a las tasas de 2019. Todas las causas de muerte específicas de las vías respiratorias disminuyeron en 2021, excepto el cáncer de pulmón, que aumentó en mujeres y disminuyó en hombres en comparación con 2019 (ambos p < 0,05). En un análisis multivariado se confirmaron algunos factores de riesgo establecidos para la mortalidad por enfermedades respiratorias, como el género masculino y la edad avanzada; además, se observó una asociación con la reducción de la mortalidad en la España rural, aun con una gran variabilidad geográfica. Conclusiones La pandemia de COVID-19 ha tenido un impacto duradero en las muertes por enfermedades respiratorias y ciertas causas específicas de muerte en 2021, y ha afectado de manera desproporcionada a ciertas regiones (AU)

Racial/Ethnic Patterns in Opioid Dispensing among Medicaid-Funded Young Children.

Racial differences in opioid dispensing for diseases of the respiratory system (RESP) and injury (INJURY) outpatient visits among patients ≤ 3 years old were examined. Outpatient claims data of South Carolina Medicaid children were analyzed over three three-year periods. The variable of interest was the triennial rate of dispensed opioid prescriptions per 1000 visits for RESP and INJURY diagnoses across racial/ethnic groups. Overall, dispensed opioid prescription rates related to RESP declined for all racial/ethnic categories. White children had the highest dispensing rate for RESP indications in the first period (5.6), followed by Black (4.5), and Hispanic (4.1). The likelihood of White children being prescribed opioids was higher than Blacks, and this was persistent over the studied time (rate ratios from 1.24 to 1.22, respectively). Overall opioid dispensing rates related to injury declined during the studied time. Hispanics had the highest dispensing rate for INJURY (20.1 to 14.8 to 16.1, respectively) followed by White (16.1 to 13.1 to 10.4, respectively). Relative differences in the dispensing rates across groups increased over time (Hispanics vs. White: rate ratios from 1.25 to 1.55, Hispanics vs. Black: from 1.52 to 2.24, and White vs. Black: from 1.24 to 1.44, respectively). There are considerable differences in the dispensing rates across racial/ethnic groups, especially in injury-related prescribing.

The Association between Exposure to Second-Hand Smoke and Disease in the Chinese Population: A Systematic Review and Meta-Analysis.

Objective: To analyze the association between exposure to second-hand smoke (SHS) and 23 diseases, categorized into four classifications, among the Chinese population. Methods: We searched the literature up to June 30, 2021, and eligible studies were identified according to the PECOS format: Participants and Competitors (Chinese population), Exposure (SHS), Outcomes (Disease or Death), and Study design (Case-control or Cohort). Results: In total, 53 studies were selected. The odds ratio (OR) for all types of cancer was 1.79 (1.56-2.05), and for individual cancers was 1.92 (1.42-2.59) for lung cancer, 1.57 (1.40-1.76) for breast cancer, 1.52 (1.12-2.05) for bladder cancer, and 1.37 (1.08-1.73) for liver cancer. The OR for circulatory system diseases was 1.92 (1.29-2.85), with a value of 2.29 (1.26-4.159) for stroke. The OR of respiratory system diseases was 1.76 (1.13-2.74), with a value of 1.82 (1.07-3.11) for childhood asthma. The original ORs were also shown for other diseases. Subgroup analyses were performed for lung and breast cancer. The ORs varied according to time period and were significant during exposure in the household; For lung cancer, the OR was significant in women. Conclusion: The effect of SHS exposure in China was similar to that in Western countries, but its definition and characterization require further clarification. Studies on the association between SHS exposure and certain diseases with high incidence rates are insufficient.

The Emergence of COVID-19 as a Cause of Death in 2020 and its Effect on Mortality by Diseases of the Respiratory System in Spain: Trends and Their Determinants Compared to 2019.

OBJECTIVE: To analyze the causes of death by diseases of the respiratory system in Spain in 2020, with special interest in COVID-19; also its trends and determinants, and compare them with 2019. MATERIAL AND METHODS: Retrospective cohort study. The coding of all those causes of death by diseases of the respiratory system were regrouped. A descriptive analysis of all deaths and by gender, age, and the 17 Autonomous Communities (CC.AA.) was performed. Also, odds ratios of death in crude and multivariate analysis by logistic regression were estimated. RESULTS: In Spain in 2020, 60,358 deaths were attributed to "COVID-19 virus identified" and another 14,481 to "COVID-19 virus not identified (suspicious)". Regrouping the specific causes of death, in 2020 the diseases of the respiratory system caused a total of 139,880 deaths, which corresponds to 28.3% of all deaths in Spain. Compared to 2019, an increase of 68.5% was observed. By gender, deaths by diseases of the respiratory system were higher in men (32.0%) than in women (24.6%), although in specific causes the percentage was higher in women with suspected COVID-19, asthma, respiratory insufficiency and other diseases of the respiratory system. Finally, the variables associated with death from COVID-19 in the multivariate analysis were being male, increasing age (maximum at 80 years), completed studies up to secondary level, employed, and single or widowed marital status, although with a marked variation by CC.AA. CONCLUSIONS: In Spain in 2020, COVID-19 produced a large increase (68.5%) in deaths by diseases of the respiratory system compared to the previous year.

Evaluation of influenza vaccination efficacy in reducing influenza-related complications and excess mortality in Northern Italy (2014-2017).

OBJECTIVE: The main objective of this study was to estimate the efficacy of influenza vaccination in reducing influenza-attributable hospitalization and emergency room (ER) admission for severe complications and influenza-attributable excess mortality in individuals ≥65 years of age. METHODS: We analyzed the ≥65 years-old community (n = 952,822) afferent to the Brescia (Northern Italy) Health Protection Agency, considered an Italian population reference, to evaluate the efficacy of influenza vaccination (seasons 2014-17) in reducing deaths, ER-admissions, and hospitalizations for influenza-related complications in the elderly. RESULTS: A protective effect of influenza vaccination emerged in reducing hospitalization and ER admission for diseases of the respiratory system and for death from all causes in people ≥65 years. The major effect of influenza vaccination was the reduction in risk of death from all causes, increasing with age and comorbidity. CONCLUSION: Influenza vaccination has reduced the number of ER admissions and hospitalizations caused by influenza-related complications and has prevented death among high-risk groups in elderly ≥65 years, resulting in social and public health cost savings. Stronger or new vaccination strategies are needed to improve vaccination rates among the elderly.

Health effects of living near an incinerator: A systematic review of epidemiological studies, with focus on last generation plants.

Huge reductions in incinerators' emissions occurred over time, and results of older studies cannot be directly generalized to modern plants. We conducted a systematic review of the epidemiologic evidence of the health effects of incinerators, classifying plants in three generations, according to emission limits. A systematic search identified 63 epidemiologic studies, published in English, investigating health effects of incinerators on humans. We focused on cancer, cardio-cerebrovascular diseases (CVD) and respiratory diseases, pregnancy outcomes and congenital anomalies. Only six studies in the general population were on third generation incinerators providing data on pregnancy outcomes and congenital anomalies. Given the heterogeneity of methods, the abundance of ecological/semi-ecological studies and the lack of reliable quantitative measures of exposure in several studies we did not perform any meta-analysis. No excesses emerged concerning all cancers and lung cancer. An excess of non-Hodgkin lymphoma was reported in some earlier studies, but not for second generation plants. Possible excesses of soft tissue sarcomas were confined to earlier incinerators and the areas closer to the plants. No clear association emerged for CVD and diseases of the respiratory system. Several different pregnancy outcomes were considered, and no consistent association emerged, in spite of a few positive results. Studies were negative for congenital anomalies as a whole. Sporadic excesses were reported in a few studies for specific types of anomalies, but no consistent pattern emerged. Evaluation of the evidence was hindered by heterogeneity in reporting and classification of outcomes across studies. Direct evidence from third generation plants is scarce. Methodological issues in study design (mainly related to exposure assessment, confounding and ecological design) and analysis make interpretation of results complex. In spite of this, the overall evidence suggests that, if there were any excesses at all for older incinerators, they were modest at most. Additional monitoring of third generation plants needs to overcome methodological weaknesses.

Avoiding hospital admissions for respiratory system diseases by complying to the final Brazilian air quality standard: an estimate for Brazilian southeast capitals.

According to the World Health Organization (WHO), in 2016, 91% of the global population was living in places where guidelines on air quality were not met, which results in an estimated figure of seven million deaths annually. The new Brazilian air quality standards, CONAMA 491/2018, was the first revision in over two decades and has as final target the WHO guidelines for air quality, although no deadline has been established for implementation. The goal of this work was to quantify public health gains of this new policy based on hospitalizations due to respiratory diseases, the most studied outcome in Brazilian time series studies, in four Brazilian Southeast capitals: São Paulo (SP), Rio de Janeiro (RJ), Belo Horizonte (MG), and Vitória (ES) for PM10, PM2,5, SO2, CO, and O3. Population and hospitalizations data for all respiratory diseases for people under 5 years old, over 64 years old, most vulnerable populations, and all ages were analyzed. The air quality monitoring data was analyzed in two different periods: 2016 to 2018 for São Paulo and Vitória; and between 2015 and 2017 for Belo Horizonte and Rio de Janeiro, according to available monitoring data. A literature review was carried out to determine the appropriate relative risk to be used in the estimations, and the public health gains were calculated based on the selected relative risks for each city. The highest estimate was for São Paulo, with 3454 avoidable respiratory hospital admissions (all ages). In total, the four cities accounted for 4148 avoidable hospitalizations, which was associated to $1.1 million public health gains. Results considering the day of exposure (lag 0) were superior to those with the 5-day moving average (lag 5). The results highlighted the importance of adopting more restrictive standards and called for public policies, the necessity of expanding the air quality monitoring network, mapping emission sources, and improve the knowledge about the interaction between air pollution and health outcomes beyond respiratory disease for the region.

Mortality Characteristics of Two Populations in the Northern Mediterranean (Croatia) in the Period 1960⁻2012: An Ecological Study.

In the second half of the 20th century, the town of Bakar (Primorje-Gorski Kotar County, Croatia), where a coking plant was operational 1978⁻1994, experienced intensive industrialisation. The town of Mali Losinj (Primorje-Gorski Kotar County, Croatia) in this period based its economy on non-industrial sectors. The study goal was comparing mortality characteristics of these populations in the northern Mediterranean for 1960⁻2012. An ecological study design was used. Data were analysed for 1960⁻2012 for the deceased with recorded place of residence in the study area. Data on the deceased for 1960⁻1993 were taken from death reports, for 1994⁻2012 from digital archives of the Teaching Institute of Public Health, Primorje-Gorski Kotar County. Data on causes of death for 1960⁻1994 were recoded to the three-digit code of underlying cause of death according to the International Classification of Diseases (ICD⁻10). Among studied populations significant difference was found among the causes of deaths coded within ICD⁻10 chapters: neoplasms (particularly stomach carcinoma), mental and behavioural disorders and diseases of the respiratory system (particularly chronic obstructive pulmonary disease, (COPD)). Increase in mortality from neoplasms, increase in respiratory diseases for the area exposed to industrial pollution, also stomach carcinoma and COPD particularly in the town Bakar require further research.

Years of life lost due to bronchial asthma in Poland between 1999 and 2013.

OBJECTIVE: The aim of this study was to analyze the years of life lost due to asthma in Poland between 1999 and 2013, with the use of the SEYLL measure (Standard Expected Years of Life Lost). METHODS: The study was based on a dataset of 5,606,516 records gathered from death certificates of Polish residents from 1999 to 2013. The data on the deaths due to bronchial asthma and status asthmaticus (J45 and J46 according to ICD-10) were used for the analysis. The SEYLL, SEYLLp (SEYLL per person) and SEYLLd (SEYLL per death) were implemented to assess lost life years. The analysis of time trends was performed with the use of the join point model. RESULTS: In 1999-2013, asthma and status asthmaticus were the cause of 11,380 deaths of Poles (0.20% of all deaths), resulting in 4.23 prematurely lost life years per 10,000 males and 3.22 years per 10,000 females. Over the analyzed years, the value of SEYLL decreased both for men and women. Every man who died due to bronchial asthma in Poland in the studied period, lost on average 19.12 years of life, and every woman 18.20 years. CONCLUSIONS: The analysis of SEYLL indicated that premature mortality due to asthma is still a meaningful problem in the Polish population and a constant challenge for public health activities.
