Effect of the COVID-19 Pandemic on Lower Respiratory Tract Infection Determinants in Thai Hospitalized Children: National Data Analysis 2015-2020

An online survey of perspectives towards the impact of the covid-19 pandemic amongst caregivers of adolescents with ASD

BACKGROUND

The coronavirus disease (COVID-19) pandemic has had a negative impact on the health and mental health of adolescents and adolescents with autism spectrum disorders (ASD) and their caregivers, have been disproportionally affected. The purpose of this study was to investigate the impact of COVID-19 on Thai caregivers and adolescents with ASD.

METHODS

This study used an online survey with closed and free text questions to investigate how the pandemic had impacted on social skills development and psychological variables, and perceived needs for support. The survey link was shared to parents via the Yuwaprasart Withayopathum Child and Adolescent Hospital and the social media platforms of known ASD stakeholder networks in Thailand. Binary logistic regression was used to investigate the relationships between sociodemographic characteristics, service use, and social skills problems experienced by adolescents during the pandemic. Content analysis was applied to analyse free-text data.

RESULTS

A total of 376 caregivers of adolescents with ASD aged 10-19 years completed the survey, of which 364 were included in the analysis. In total, 38.7% of caregivers reported that during the pandemic the social skills of their adolescent family member had worsened. Most families reported that they were able to continue to access support from healthcare and educational services, albeit in different ways than pre-pandemic, during the acute stages of the pandemic which benefited the maintenance of ASD symptoms and social skills. Factors identified as reducing the odds of a worsening in social skills during the pandemic included; regular access to treatment for adolescents (odds ratio [OR] = 0.55, confidence interval 95% (CI) 0.32-0.98, p = 0.044), caregivers feeling that they had sufficient support from hospitals (OR = 0.46, 95% CI 0.26-0.81, p = 0.007) and older age of adolescents (OR = 0.53, CI 0.29-0.99, p = 0.047). The qualitative free text comments showed that the caregivers felt that greater information on managing adolescent behaviours, opportunities for adolescents to practice social skills, and the provision of greater emotional support and material assistance from healthcare professionals during the pandemic would have helped them to care for the adolescents with ASD.

CONCLUSION

Regular access to services, support from hospitals during the pandemic and older age in adolescence may have helped prevent the worsening of the social skills problems of adolescents with ASD.

Is There a Role for Immunostimulant Bacterial Lysates in the Management of Respiratory Tract Infection?

Bacterial Lysates are immunostimulants clinically prescribed for the prevention of respiratory tract infections (RTIs). It has been shown that Bacterial Lysates upregulate the immune system, acting both on innate and adaptive reactions. In fact, there are demonstrations of their efficacy in restoring the integrity and immune function of epithelial barriers, activating ILC3 and dendritic cells with an enhanced Th1 response, and producing serum IgG and serum and salivary IgA specific to the administered bacterial antigens. The activated immune system also protects against other bacteria and viruses due to a trained immunity effect. Most studies show that the number of RTIs and their severity decrease in Bacterial Lysates-pretreated patients, without relevant side effects. The Bacterial Lysates treatment, in addition to reducing the number of RTIs, also prevents the deterioration of the underlying disease (i.e., COPD) induced by repeated infections. Despite these positive data, the most recent meta-analyses evidence the weakness of the studies performed, which are of low quality and have an inadequate number of patients, some of which were non-randomized while others were without a control group or were performed contemporarily in different clinical conditions or with different ages. The high heterogeneity of the studies does not allow us to state Bacterial Lysates' effectiveness in preventing RTIs with sufficient certainty. To completely define their indications, double-blind, placebo-controlled, multicenter, randomized clinical trials should be performed for each product and for each indication. The study population should be adequate for each indication. For this purpose, an adequate run-in phase will be necessary.

Clinical Characteristics and Outcomes of Pediatric COVID-19 Pneumonia Treated with Favipiravir in a Tertiary Care Center

The COVID-19 pandemic, caused by SARS-CoV-2, has posed significant health challenges worldwide. While children generally experience less severe illness compared to adults, pneumonia remains a substantial risk, particularly for those under five years old. This study examines the clinical characteristics and treatment outcomes of pediatric COVID-19 pneumonia patients treated with favipiravir in Thailand, aiming to identify associated factors for pneumonia. A retrospective review was performed on pediatric patients aged 1 month to 18 years hospitalized with COVID-19 at Srinagarind Hospital, Khon Kaen University, from 13 January 2020 to 15 November 2021. Data on demographics, clinical symptoms, treatment, and outcomes were collected, and logistic regression analysis was used to identify factors associated with pneumonia. Among 349 hospitalized children, the median age was 8 years, with 51.9% being male. Symptoms included a fever (100%), a cough (74.2%), and a rash (24.9%). COVID-19 pneumonia was diagnosed in 54.7% of the children. Favipiravir was administered as the standard treatment, showing mild adverse effects, including a rash (4.3%) and nausea (2.8%). Monocytosis was significantly associated with COVID-19 pneumonia (aOR 30.85, 95% CI: 9.03-105.41, p < 0.001), with an ROC curve area of 0.77 (95% CI: 0.71-0.83). Pediatric COVID-19 patients typically exhibit mild-to-moderate symptoms, with pneumonia being common in the early pandemic phase. Monocytosis is a significant factor associated with COVID-19 pneumonia. Favipiravir demonstrated mild adverse effects. Further studies are needed to validate these findings across different settings and phases of the pandemic.

Incidence of Respiratory Syncytial Virus-Associated Lower Respiratory Tract Illness in Infants in Low- and Middle-Income Regions During the Coronavirus Disease 2019 Pandemic

Background

Incidence data of respiratory syncytial virus-associated lower respiratory tract illness (RSV-LRTI) are sparse in low- and middle-income countries (LMICs). We estimated RSV-LRTI incidence rates (IRs) in infants in LMICs using World Health Organization case definitions.

Methods

This prospective cohort study, conducted in 10 LMICs from May 2019 to October 2021 (largely overlapping with the coronavirus disease 2019 [COVID-19] pandemic), followed infants born to women with low-risk pregnancies for 1 year from birth using active and passive surveillance to detect potential LRTIs, and quantitative reverse-transcription polymerase chain reaction on nasal swabs to detect RSV.

Results

Among 2094 infants, 32 (1.5%) experienced an RSV-LRTI (8 during their first 6 months of life, 24 thereafter). Seventeen (0.8%) infants had severe RSV-LRTI and 168 (8.0%) had all-cause LRTI. IRs (95% confidence intervals [CIs]) of first RSV-LRTI episode were 1.0 (.3-2.3), 0.8 (.3-1.5), and 1.6 (1.1-2.2) per 100 person-years for infants aged 0-2, 0-5, and 0-11 months, respectively. IRs (95% CIs) of the first all-cause LRTI episode were 10.7 (8.1-14.0), 11.7 (9.6-14.0), and 8.7 (7.5-10.2) per 100 person-years, respectively. IRs varied by country (RSV-LRTI: 0.0-8.3, all-cause LRTI: 0.0-49.6 per 100 person-years for 0- to 11-month-olds).

Conclusions

RSV-LRTI IRs in infants in this study were relatively low, likely due to reduced viral circulation caused by COVID-19-related nonpharmaceutical interventions.

Epidemiological change of influenza virus in hospitalized children with acute respiratory tract infection during 2014-2022 in Hubei Province, China

PURPOSE

Influenza virus (IFV) causes acute respiratory tract infection (ARTI) and leads to high morbidity and mortality annually. This study explored the epidemiological change of IFV after the implementation of the universal two-child policy and evaluated the impact of coronavirus disease 2019 (COVID-19) pandemic on the detection of IFV.

METHODS

Hospitalized children under 18 years with ARTI were recruited from Hubei Maternal and Child Healthcare Hospital of Hubei Province from January 2014 to June 2022. The positive rates of IFV were compared among different periods by the implementation of the universal two-child policy and public health measures against COVID-19 pandemic.

RESULTS

Among 75,128 hospitalized children with ARTI, the positive rate of IFV was 1.98% (1486/75128, 95% CI 1.88-2.01). Children aged 6-17 years had the highest positive rate of IFV (166/5504, 3.02%, 95% CI 2.58-3.50). The positive rate of IFV dropped to the lowest in 2015, then increased constantly and peaked in 2019. After the universal two-child policy implementation, the positive rate of IFV among all the hospitalized children increased from 0.40% during 2014-2015 to 2.70% during 2017-2019 (RR 6.72, 95% CI 4.94-9.13, P < 0.001), particularly children under one year shown a violent increasing trend from 0.20 to 2.01% (RR 10.26, 95% CI 5.47-19.23, P < 0.001). During the initial outbreak of COVID-19, the positive rate of IFV decreased sharply compared to that before COVID-19 (0.35% vs. 3.37%, RR 0.10, 95% CI 0.04-0.28, P < 0.001), and then rebounded to 0.91%, lower than the level before COVID-19 (RR 0.26, 95% CI 0.20-0.36, P < 0.001).

CONCLUSION

IFV epidemiological pattern has changed after the implementation of the universal two-child policy. More attention should be emphasized to comprehend the health benefits generated by COVID-19 restrictions on IFV transmission in future.

Parental Attitude, Knowledge, and Practices Regarding the Usage of Antibiotics for Upper Respiratory Tract Infections in Children During the COVID-19 Pandemic

BACKGROUND

The COVID-19 pandemic has raised knowledge of the proper antibiotic dosage for treating childhood upper respiratory tract infections (URTIs). In order to ensure proper antibiotic usage and prevent the establishment of illnesses that is antibiotic-resistant during the COVID-19 pandemic, parental attitudes, knowledge, and behaviour surrounding antibiotic use for URTIs in children are essential. The goal of this study was to find out the parental attitude, knowledge, and practices regarding the usage of antibiotics for URTIs in children during the COVID-19 epidemic.

METHODOLOGY

This cross-sectional was conducted in the Department of Paediatric Medicine, Central Hospital, Ganesh Nagar, New Delhi, India from September 2022 to February 2023. The study analysed a total of 500. All the children had URTIs. A structured questionnaire was randomly distributed among parents. Socio-demographic information like gender, age, occupation, monthly family income, and age of the children were noted at the time of enrollment. Outcomes were recorded in terms of responses to questions regarding attitude, knowledge, and practices regarding the use of antibiotics for URTIs in children during the COVID-19 epidemic.  Results: Of a total of 500 parents, 380 (76.0%) were male. The mean age was 39.9±8.3 years while 280 (56.0%) participants were aged between 31 to 45 years. Relatively older age (p<0.0001) and occupational status as unemployed (p<0.0001) were found to have a significant association with response to "virus being the cause of COVID-19". Females (p=0.0004) and increasing age (p<0.0001) were found to have significant associations with incorrect responses to "antibiotics are essential for managing the symptoms in children with COVID-19". Incorrect responses to "without the use of antibiotics, children usually suffer from greater periods of sickness" were associated with females and increasing age (p<0.0001). Incorrect responses to "not using antibiotics will prove beneficial for the children suffering from COVID-19" were significantly associated with female gender (p=0.0016) and increasing age (p<0.0001). The incorrect responses to "how often are antibiotics being prescribed to the COVID-19 children" was significantly linked with females and relatively older age (p<0.0001).

CONCLUSIONS

Parental attitude, knowledge, and practices regarding the usage of antibiotics for URTIs in children during the COVID-19 epidemic showed variations. Parental attitude, knowledge, and practices were associated with gender, age, and socio-economic status.

Characteristics of Respiratory Syncytial Virus Infection in Hospitalized Children Before and During the COVID-19 Pandemic in Thailand

OBJECTIVES

This study compared the epidemiological and clinical manifestations of patients hospitalized with respiratory syncytial virus (RSV) infection before and during the coronavirus disease 2019 (COVID-19) pandemic at a tertiary care hospital in Chiang Mai Province, Thailand.

METHODS

This retrospective observational study utilized data from all cases of laboratory-confirmed RSV infection at Maharaj Nakorn Chiang Mai Hospital from January 2016 to December 2021. Differences in the clinical presentation of RSV infection before (2016 to 2019) and during (2020 to 2021) the COVID-19 pandemic were analyzed and compared.

RESULTS

In total, 358 patients hospitalized with RSV infections were reported from January 2016 to December 2021. During the COVID-19 pandemic, only 74 cases of hospitalized RSV infection were reported. Compared to pre-pandemic levels, the clinical presentations of RSV infection showed statistically significant decreases in fever on admission (p=0.004), productive cough (p=0.004), sputum (p=0.003), nausea (p=0.03), cyanosis (p=0.004), pallor (p&lt;0.001), diarrhea (p&lt;0.001), and chest pain (p<0.001). Furthermore, vigilant measures to prevent the spread of COVID-19, including lockdowns, also interrupted the RSV season in Thailand from 2020 to 2021.

CONCLUSIONS

The incidence of RSV infection was affected by the COVID-19 pandemic in Chiang Mai Province, Thailand, which also changed the clinical presentation and seasonal pattern of RSV infection in children.

Prevalence of Respiratory Infections during the 2018-2020 Period in the Paediatric Population of Primary Care Centres in Central Catalonia

Following the COVID-19 pandemic, policies such as social distancing, hand washing, and the use of masks were implemented, which could play an important role in the reduction of infectious diseases. An observational, descriptive, cross-sectional study was conducted to observe the prevalence of respiratory infections in children under 15 years of age during the 2018-2020 period in Primary Care centres in Central Catalonia. In 2020, there was a 44.3% decrease in total consultations for respiratory infections compared to 2019. All respiratory infections exhibited a significant decrease except flu-like syndrome; children between the ages of 6 and 12 had the highest prevalence of flu-like syndrome (87.6%), and the SARS-CoV-2-19 infection was most frequent (4%) among those between the ages of 12 and 15. Compared to urban centres, rural centres presented a higher prevalence of all infections except flu-like syndrome and SARS-CoV-2. In conclusion, the COVID-19 pandemic caused a significant decrease in the number of consultations for respiratory infections in the paediatric population, except for flu-like syndrome, which increased in cases in January, February, and March 2020. No differences were found between sexes, although differences were found in the distribution of the different age groups.

Clinical Hematochemical Parameters in Differential Diagnosis between Pediatric SARS-CoV-2 and Influenza Virus Infection: An Automated Machine Learning Approach

BACKGROUND

The influenza virus and the novel beta coronavirus (SARS-CoV-2) have similar transmission characteristics, and it is very difficult to distinguish them clinically. With the development of information technologies, novel opportunities have arisen for the application of intelligent software systems in disease diagnosis and patient triage.

METHODS

A cross-sectional study was conducted on 268 infants: 133 infants with a SARS-CoV-2 infection and 135 infants with an influenza virus infection. In total, 10 hematochemical variables were used to construct an automated machine learning model.

RESULTS

An accuracy range from 53.8% to 60.7% was obtained by applying support vector machine, random forest, k-nearest neighbors, logistic regression, and neural network models. Alternatively, an automated model convincingly outperformed other models with an accuracy of 98.4%. The proposed automated algorithm recommended a random tree model, a randomization-based ensemble method, as the most appropriate for the given dataset.

CONCLUSIONS

The application of automated machine learning in clinical practice can contribute to more objective, accurate, and rapid diagnosis of SARS-CoV-2 and influenza virus infections in children.

Health-Risk Behaviors, COVID-19 Preventive Behaviors, and the Impact of the COVID-19 Pandemic on the Working-Age Population of Bangkok, Thailand

Although studies have extensively discussed the effects of COVID-19 on global health behaviors, little is known about the extent of COVID-19 preventive behaviors and their negative effects on the working-age population of Bangkok, Thailand. Therefore, this study aimed to examine health-risk behaviors, COVID-19 preventive behaviors, and the impact of the COVID-19 pandemic among the Thai working-age population. An online cross-sectional survey was conducted among working-age adults through a self-administered questionnaire. Data were analyzed with descriptive statistics and stepwise multiple regression. Of the 313 Thai participants (227 females, 72.5%), 84.0% had high levels of health-risk behaviors for preventing COVID-19 infection, most respondents (89.1%) had high levels of knowledge about COVID-19, and most respondents (61.7%) had high levels of overall COVID-19 preventive behaviors. Stepwise multiple regression revealed that health-risk behaviors (β = 0.445), knowledge of COVID-19 (β = 0.148), gender (β = 0.145), and age (β = 0.133) were predictive of COVID-19 preventive behaviors. Additionally, most respondents (48.9%) had moderate overall effects from COVID-19. Based on our findings, these factors must be considered when implementing public policies to improve COVID-19 preventive behaviors among the currently employed working-age population. In addition, appropriate interventions must be established and evaluated for the pandemic's long-term effects.

Factors Predicting the Coronavirus Disease 2019 Preventive Behaviors of Older Adults: A Cross-Sectional Study in Bangkok, Thailand

The coronavirus disease 2019 (COVID-19) pandemic has affected the health behaviors of older adults. Thus, the factors predicting the COVID-19 preventive behaviors of older adults during the COVID-19 outbreak should be examined. Therefore, this study aimed to assess the COVID-19 preventive behaviors of older adults and explore the factors predicting these. A cross-sectional study was performed with 400 older adults who were selected using the cluster sampling technique. The associations of all variables in preventing COVID-19 infection with COVID-19 preventive behaviors were examined using stepwise multiple regression. The study results revealed that 70.8% of the study participants had high levels of COVID-19 preventive behaviors. Among these, self-efficacy in preventing COVID-19 infection (β = 0.224) showed the highest ability to predict COVID-19 preventive behaviors, followed by COVID-19 response efficacy (β = 0.171), knowledge about COVID-19 (β = 0.110), and gender (β = -0.102). Older adults adopted protective behaviors at the beginning of the COVID-19 pandemic. The predictors of these behaviors should be considered while designing and developing appropriate COVID-19 preventive behavior interventions, aimed at inducing behavioral modifications to reduce further infection with and spread of COVID-19.
