Cardiac injury is associated with mortality and critically ill pneumonia in COVID-19: A meta-analysis.

Background: In this systematic review and meta-analysis, we aimed to explore the association between cardiac injury and mortality, the need for intensive care unit (ICU) care, acute respiratory distress syndrome (ARDS), and severe coronavirus disease 2019 (COVID-19) in patients with COVID-19 pneumonia. Methods: We performed a comprehensive literature search from several databases. Definition of cardiac injury follows that of the included studies, which includes highly sensitive cardiac troponin I (hs-cTnl) >99th percentile.The primary outcome was mortality, and the secondary outcomes were ARDS, the need for ICU care, and severe COVID-19. ARDS and severe COVID-19 were defined per the World Health Organization (WHO) interim guidance of severe acute respiratory infection (SARI) of COVID-19. Results: There were a total of 2389 patients from 13 studies. This meta-analysis showed that cardiac injury was associated with higher mortality (RR 7.95 [5.12, 12.34], p < 0.001; I2: 65%). Cardiac injury was associated with higher need for ICU care (RR 7.94 [1.51, 41.78], p = 0.01; I2: 79%), and severe COVID-19 (RR 13.81 [5.52, 34.52], p < 0.001; I2: 0%). The cardiac injury was not significant for increased risk of ARDS (RR 2.57 [0.96, 6.85], p = 0.06; I2: 84%). The level of hs-cTnI was higher in patients with primary + secondary outcome (mean difference 10.38 pg/mL [4.44, 16.32], p = 0.002; I2: 0%). Conclusion: Cardiac injury is associated with mortality, need for ICU care, and severity of disease in patients with COVID-19.

The Fungal and Bacterial Interface in the Respiratory Mycobiome with a Focus on Aspergillus spp.

The heterogeneity of the lung microbiome and its alteration are prevalently seen among chronic lung diseases patients. However, studies to date have primarily focused on the bacterial microbiome in the lung rather than fungal composition, which might play an essential role in the mechanisms of several chronic lung diseases. It is now well established that Aspergillus spp. colonies may induce various unfavorable inflammatory responses. Furthermore, bacterial microbiomes such as Pseudomonas aeruginosa provide several mechanisms that inhibit or stimulate Aspergillus spp. life cycles. In this review, we highlighted fungal and bacterial microbiome interactions in the respiratory tract, with a focus on Aspergillus spp.

Clinical characteristics and quality of life of persistent symptoms of COVID-19 syndrome in Indonesia.

Introduction: Coronavirus disease-2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) manifests in a broad clinical spectrum. COVID-19 survivors report various symptoms up to several months after being infected. The purpose of this study was to determine the prevalence of persistent COVID-19 syndrome in Indonesia, the factors that influence the incidence, and the quality of life. Methods: This was a cross-sectional study with an online questionnaire conducted in January 2021. Inclusion criteria were: adult Indonesian citizens who had recovered from COVID-19, and were confirmed negative by RT-PCR of nasal swabs or had undergone an isolation period for a minimum of 14 days. Data analysis was performed by the Chi-square test, followed by multivariate analysis with the backward likelihood ratio method. Results: From a total of 385 respondents, 256 (66.5%) experienced persistent COVID-19 syndrome. The most prevalent symptoms were fatigue (29.4%), cough (15.5%), and muscle pain (11.2%). Of the five aspects of quality of life, the most commonly reported aspects were pain/discomfort and anxiety/depression. The risk of persistent COVID-19 syndrome was significantly higher in subjects with older age, comorbidities, higher clinical severity, previous treatment in hospital, presence of pneumonia, and those who had required oxygen therapy. In the multivariate analysis, the most influential factor for the incidence of persistent COVID-19 syndrome was pneumonia (aOR 2.31, 95% CI 1.29-4.11, p<0.002). Conclusions: The prevalence of the persistent COVID-19 syndrome in Indonesia was high, which affects the quality of life of COVID-19 survivors. Pneumonia was the main factor that influenced the incidence of persistent COVID-19 syndrome. Further research with a larger sample size and a longer study time is recommended to control COVID-19 and its impact on the health and quality of life of COVID-19 survivors.

Correlation between Domestic Cigarette Smoke Exposure and Respiratory Complaints, Hospitalization and School Absence due to Respiratory Complains in the Indonesian Elementary School-Aged Children.

BACKGROUND: Over 43 million Indonesian children who are exposed to cigarette smoke are at risk of having health hazard and morbidities. AIMS: The aim of this study is to identify the correlation between cigarette smoke exposure and respiratory complaints, hospitalization, as well as school absence due to respiratory complaints in elementary school-aged Indonesian children. MATERIALS AND METHODS: A cross-sectional study was conducted in nonsmoking elementary school-aged children. Participants were categorized into the exposed and unexposed groups based on the report of their parents. Questionnaire-retrieved data were analyzed to identify the correlation between cigarette smoke exposure and respiratory complaints, hospitalization, as well as school absence due to respiratory complaints in elementary school-aged children. RESULTS: A total of 128 study participants of nonsmoking children aged 6-12 years (mean 9.8 ± standard deviation 1.6 years) were categorized into 64 children exposed and 64 children unexposed to domestic cigarette smoking. There was a significant correlation between smoking exposure and cough episodes as well as upper respiratory infection in children within the past 12 months. A cough episode of ≥3 times/year was found more prevalent in exposed children compared to the unexposed children (26.6% vs. 9.4%; P < 0.05). Cough ≥3 times/year was found in 50% of children exposed to cigarette smoke of a smoker with a smoking habit of >10 cigarettes/day. There was a correlation between cigarette smoke exposure and hospitalization frequency of ≥1 time(s)/year due to respiratory complaints in children (P < 0.05). CONCLUSION: Cigarette smoke exposure is correlated with complaints of cough, upper respiratory tract infection, and hospitalization due to respiratory complaints in children.

Spirometry findings among drug users in the Indonesian National Narcotics and illicit drug Bureau Rehabilitation Center.

BACKGROUND: The increasing prevalence of drug user in Indonesia is affecting the health sectors. The lungs health were affected by the use of the illicit drug. However, lung function among drug users is still unclear. METHODS: This descriptive-analytic study involves 144 drug users who met the inclusion criteria. Chest X-ray was performed to identify the subject with pulmonary tuberculosis to exclude from the study. Subjects were then undergone spirometry test and interviewed using questionnaires. RESULTS: One hundred and forty-four subjects were included in this study. One hundred and twenty-one (84.03%) were male and 128 subjects showed normal lung function. Proportion of abnormal spirometry was 10.4% (n = 15). The restriction was found in ten subjects, and obstruction was found in four subjects. There was significant correlation between the ratio of forced expiratory volume in 1 s to forced vital capacity (FEV1/FVC) and age (P = 0.000; r = -0.454, moderate correlation), time of using cannabis (P = 0.01; r = -0.345, weak correlation), time of using methamphetamine inhalation (P = 0.004; r = -0.25, weak correlation), duration of using heroin injection (P = 0.025; r = -0.337, weak correlation), time of using cigarette (P = 0.000; r = -0.365, weak correlation), and the amount of cigarette consumption/day (P = 0.04; r = -0.238, weak correlation). CONCLUSION: This study found that there was a weak correlation between declined FEV1/FVC with a time of smoking, the amount of cigarette consume per day, time of cannabis inhalation, time of methamphetamine inhalation, and time of heroin injection.

Genetic variations in detoxification enzymes and HIF-1α in Japanese patients with COPD.

INTRODUCTION: Genetic factors contribute as major determinants in the pathophysiological mechanisms of chronic obstructive pulmonary disease (COPD). Therefore, identification of candidate genes and various gene polymorphisms have improved our understanding of COPD. OBJECTIVES: Clarify the genes, including HIF1A, that contribute to the development of COPD. METHODS: We compared the genotype frequencies of 12 polymorphisms in seven detoxification-related genes (GSTM1, GSTT1, GSTP1 exon 5, CYP1A1 exon 7, CYP1A1 3'-flanking, CYP2E1 intron 6, CYP2E1 5'-flanking, EPHX1 exon 3, EPHX1 exon 4 and HMOX1 promoter) and the hypoxia-related HIF1A (C1772T and G1790A) genes between 48 Japanese patients with work-related COPD who had a working history in a poison gas factory during World War II and two control groups (n=172 and 110 subjects, respectively). RESULTS: As expected, wild homozygotes for GSTP1 Ile105Val and EPHX1 slow/very slow phenotypes were associated with susceptibility (P=0.031) and severity (P=0.036) of COPD, respectively. Moreover, compound heterozygosity of transcription-activating HIF1A polymorphisms was observed in two patients with COPD, but not in control individuals (P=0.091). CONCLUSION: This is the first report that examined HIF1A polymorphisms in COPD and demonstrated a possible role of HIF-1α in COPD, as well as GSTP1 and EPHX1.
