BACKGROUND:
There is growing evidence that the occurrence and severity of respiratory diseases in children are related to the concentration of air pollutants. Nonetheless, evidence regarding the association between short-term exposure to air pollution and outpatient visits for respiratory diseases in children remains limited. Outpatients cover a wide range of disease severity, including both severe and mild cases, some of which may need to be transferred to inpatient treatment. This study aimed to quantitatively evaluate the impact of short-term ambient air pollution exposure on outpatient visits for respiratory conditions in children.
METHODS:
This study employed data of the Second People's Hospital of Yichang from January 1, 2016 to December 31, 2023, to conduct a time series analysis. The DLNM approach was integrated with a generalized additive model to examine the daily outpatient visits of pediatric patients with respiratory illnesses in hospital, alongside air pollution data obtained from monitoring stations. Adjustments were made for long-term trends, meteorological variables, and other influencing factors.
RESULTS:
A nonlinear association was identified between PM2.5, PM10, O3, NO2, SO2, CO levels and the daily outpatient visits for respiratory diseases among children. All six pollutants exhibit a hysteresis impact, with varying durations ranging from 4 to 6 days. The risks associated with air pollutants differ across various categories of children's respiratory diseases; notably, O3 and CO do not show statistical significance concerning the risk of chronic respiratory conditions. Furthermore, the results of infectious respiratory diseases were similar with those of respiratory diseases.
CONCLUSIONS
Our results indicated that short-term exposure to air pollutants may contribute to an increased incidence of outpatient visits for respiratory illnesses among children, and controlling air pollution is important to protect children's health.

PURPOSE:
Geographical analysis is becoming a powerful tool for evaluating the quality of medical services and acquiring fundamental data for medical decision-making. Using geographical analysis, we evaluated the impact of the distance from patients' homes to the hospital on their participation in outpatient cardiac rehabilitation (OCR).
METHODS:
All patients hospitalized for percutaneous coronary intervention, coronary artery bypass grafting, valvular surgery, congestive heart failure, and aortic diseases were advised to participate in an OCR program after discharge. Using the dataset of our cohort study of OCR from 2004 to 2015 (n = 9,019), we used geographical analysis to investigate the impact of the distance from patients' homes to hospital on their participation in our OCR program.
RESULTS:
Patients whose road distance from home to hospital was 0-10 km, 10-20 km, and 20-30 km participated more in OCR than those whose road distance was ≧ 30 km (OR 4.34, 95% CI 3.80-4.96; OR 2.98, 95% CI 2.61-3.40; and OR 1.90, 95% CI 1.61-2.23, respectively). Especially in patients with heart failure, the longer the distance, the lesser the participation rate (P < .001).
CONCLUSIONS:
Using geographical analysis, we successfully evaluated the factors influencing patients' participation in OCR. This illustrates the importance of using geographical analysis in future epidemiological and clinical studies.

BACKGROUND: The incidence of cutaneous malignant tumors and premalignant lesions has recently increased worldwide. However, studies investigating the incidence and clinical manifestations of cutaneous malignant tumors and premalignant lesions in Korea are rare, especially in southeastern Gyeonggi-do Province. OBJECTIVE: To analyze the recent trends in the incidence of cutaneous malignant tumors and premalignant lesions in southeastern Gyeonggi-do Province. METHODS: We retrospectively reviewed 451 cases of cutaneous malignant tumors and 455 cases of premalignant lesions from 2006 to 2016. RESULTS: The average annual incidence rates of cutaneous malignant tumors and premalignant lesions among the total number of outpatients was 0.84% and 0.85%, respectively, and both these rates increased significantly over time. Basal cell carcinoma was most commonly diagnosed cutaneous malignant tumor (50.8%), followed by squamous cell carcinoma (24.6%), malignant melanoma (8.2%), and metastatic carcinoma (5.1%). The most common premalignant lesion was actinic keratosis (60.0%). The mean age of the patients with cutaneous malignant tumors and premalignant lesions was 68.8 years and 70.8 years, respectively. The ratio of male to female patients was 1 : 1.19 for cutaneous malignant tumors and 1 : 2.01 for premalignant lesions. The face was the most common site for both cutaneous malignant tumors and premalignant lesions (at 71.9% and 75.8%, respectively). CONCLUSION: This retrospective study provided data about the incidence and clinical patterns of cutaneous malignant tumors and premalignant lesions among patients in southeastern Gyeonggi-do Province.

OBJECTIVES: This study was performed to examine the effects of the public attention to ‘crime of schizophrenia’ on the use of mental health services in patients with schizophrenia using big data analysis. METHODS: Data on the frequency of internet searches for ‘crime of schizophrenia’ and the patterns of mental health service utilization by patients with schizophrenia spectrum disorders by month were collected from Naver big data and the Health Insurance Review and Assessment Services in Korea, respectively. Their correlations in the same and following month for lagged effect were examined. RESULTS: The number of outpatients correlated negatively with public attention to ‘crime of schizophrenia’ in the same month. The lagged relationship between public attention and the number of admissions in psychiatric wards was also found. In terms of sex differences, the use of outpatient services among female patients correlated negatively with public attention in the same month while the number of male patients' admissions in both same and following month correlated positively with public attention. CONCLUSION: These findings suggested that public attention to ‘crime of schizophrenia’ could negatively affect illness behavior in patients with schizophrenia.

6.Canonical Correlation Between Self-Care Agency and Health-Related Self-Efficacy with Chronic Viral Hepatitis Patients
Osong Public Health and Research Perspectives 2019;10(5):281-288
OBJECTIVES: The purpose of this study was to examine the relationship between self-care agency and health self-efficacy measures, in patients with viral hepatitis. METHODS: Data were collected from 116 outpatients over the age of 19 years who were diagnosed with viral hepatitis between February 20, 2019 and April 30, 2019. This study used the Appraisal of Self-care Agency Scale-Revised and the Health Self-Efficacy measures. Descriptive statistics, Pearson’s correlation coefficients, and canonical correlations were used during data analysis [SPSS version 25.0 for Windows (SPSS, Chicago, IL, USA)]. RESULTS: The first canonical correlation coefficient was 0.65 (Wilks’ λ = 0.44, F = 5.63, p < 0.001) and the second was 0.42 (Wilks’ λ = 0.76, F = 3.08, p = .001). The first variate indicated a higher perception of having power for self-care (0.85) and developing power for self-care (0.92), and this was related to exercise (0.66), illness (0.76), emotion (0.75), nutrition (0.81), stress (0.60), and health practice (0.85). The second variate indicated a higher perception of having power for self-care (0.42), whilst lacking power for self-care (−0.82), was related to illness (0.35) and stress (0.72). CONCLUSION: Nursing interventions and education aimed at enhancing the self-care of viral hepatitis patients are needed to assist patients to improve their health care behaviors.

INTRODUCTIONLiterature has shown that individuals with various psychiatric disorders experience a lower quality of life (QoL). However, few have examined QoL across disorders. The current study explored differences in QoL and symptom severity across 4 psychiatric diagnostic groups: anxiety disorders (including obsessive compulsive disorder [OCD]), depressive disorders, schizophrenia, and pathological gambling.
MATERIALS AND METHODSData analysed was from a previous study that examined the prevalence of hoarding symptoms among outpatients (n = 500) in a tertiary psychiatric hospital in Singapore. Measures utilised included the Beck Anxiety Inventory (BAI), Beck Depression Inventory-II (BDI-II) and Quality of Life Enjoyment and Satisfaction QuestionnaireShort Form (Q-LES-Q-SF). Sociodemographic information and details on type and number of comorbidities were also collected.
RESULTSThe depressive disorder group had the highest level of depressive and anxiety symptoms and the lowest QoL whereas; the schizophrenia group had the lowest level of depressive symptoms and the highest QoL. Age and employment status were the only sociodemographic correlates which were significantly associated with QoL. After controlling for sociodemographic factors, only the type of mental disorder was found to have a significant effect in explaining BAI, BDI-II and Q-LES-Q-SF.
CONCLUSIONFindings offer insight in terms of the burden associated with the various disorders.

Objective: To understand the clinical characteristics and economic burden of influenza-like illness (ILI) children aged 0-59 months in the outpatient settings in Suzhou, China, 2011-2017. Methods: From March 2011 to February 2017, we conducted a prospective surveillance program on ILI for children aged less than 5 years at Soochow University Affiliated Children's Hospital. Through standard questionnaires and follow-up survey via telephone, we collected information regarding the demographic characteristics, medical history, clinical symptoms and both direct and indirect costs associated with influenza, of the patients. We then compared clinical characteristics and economic burden of influenza A/H1N1, A/H3N2, and B infections among children with ILI. Results: We enrolled 6 310 patients with ILI from March 2011 to February 2017 and collected all their throat swabs. 791 (12.9%) of the swabs showed positive for influenza virus, including 88 (11.1%) subtype influenza A/H1N1, 288 (36.4%) subtype influenza A/H3N2, and 415(52.5%) type influenza B. The proportions of cough, rhinorrhea, wheezing, vomiting and convulsion in influenza-positive children were higher than those influenza-negative children. Except for the prevalence rates of cough (χ(2)=9.227, P=0.010), wheezing (χ(2)=7.273, P=0.026) and vomiting (χ(2)=8.163, P=0.017), other clinical symptoms appeared similar between the three viral subtypes. Among all the ILI children, the average total cost per episode of influenza was 688.4 Yuan (95%CI: 630.1-746.7) for influenza-negative children; 768.0 Yuan (95%CI: 686.8-849.3) for influenza-positive children and 738.3 Yuan (95%CI: 655.5-821.1) for influenza B. Children with influenza A/H1N1 spent much more than those with influenza A/H3N2 or influenza B in the total cost (χ(2)=7.237, P=0.028). Conclusion: Children infected influenza showed higher prevalence rates of cough, rhinorrhea, wheezing, vomiting and convulsion than those without influenza. Influenza A/H1N1 subtype caused heavier economic burden than the other two influenza subtypes.

Objective: To analyze the reasons for the fluctuations in the percentage of outpatient or emergency visits for influenza-like illness (ILI) during the Spring Festival and National Day in 2014-2018 surveillance season. Methods: ILI surveillance data was collected during the period of Spring Festival and National Day in mainland China, and downloaded from Chinese Influenza Surveillance Information System, during the 2014-2018 surveillance season. Results: There was no significant difference noticed in the number of ILI reports in the festival week with weeks before or after in both the southern and northern provinces. The number of outpatient visits was much less than that of the week before and after, but the number of emergency visits was statistically significantly increased. Conclusion: In the holiday peak of ILI%, the major causes was the impact of holiday-off at sentinel hospitals, resulting in a large reduction in the number of outpatient visits in the consulting room during the festivals.
