Abstract
Background Sleep quality could be affected by air pollution, especially for particulate matter with a diameter of less than 10 microns (PM10) and particulate matter with a diameter of less than 2.5 microns (PM2.5). However, no direct study demonstrates the relationship and impact of air pollution especially PM10 and PM2.5 on continuous positive airway pressure (CPAP) adherence. Thus, we aimed to study the correlation between PM10, PM2.5, and low CPAP adherence in subjects with obstructive sleep apnea (OSA). Methods We conducted a time-series study from August 2016 to May 2022 in Chiang Mai, Thailand. The data from 2,686 visits of CPAP compliance records from 839 OSA patients' electronic medical records at the Sleep Disorders Center, Center of Medical Excellence, Chiang Mai University, Chiang Mai, Thailand were reviewed. The level of adherence was determined utilizing the provided data. Low CPAP adherence was defined as using CPAP for less than 240 minutes per night or less than 70% of nights (i.e., <5 nights/week) in the previous month. The correlation between the monthly average of PM10 and PM2.5 and the rate of low CPAP adherence was analyzed using generalized linear mixed model (GLMM) after adjustment for confounding factors. Results There was no effect of an increase in PM10 and PM2.5 on low CPAP adherence [adjusted risk ratio (RR) =0.97; 95% confidence interval (CI): 0.87, 1.09; P value =0.624 and adjusted RR =0.93; 95% CI: 0.81, 1.08; P value =0.350 for PM10 and PM2.5, respectively]. Conclusions There was no effect of particulate matter on CPAP adherence in OSA patients.

Abstract
Background and Objectives: After recovering from COVID-19, patients may experience persistent symptoms, known as post-COVID-19 syndrome or long COVID, which include a range of continuing health problems. This research explores the prevalence, associated factors, and overall health outcomes of long COVID during a period of extensive vaccination and antiviral treatment availability in Thailand. Materials and Methods: This observational study involved 390 adult patients with COVID-19 between January and March 2022. Beginning three months after their diagnosis, these patients were interviewed via telephone every three months for a period of one year. The data collection process included gathering demographic information and administering a standardized questionnaire that addressed the patients' physical condition following COVID-19, their mental health, sleep disturbances, and overall quality of life. Results: The cohort consisted of 390 participants, with an average age of 31.8 ± 13.6. Among them, 96.7% (n = 377) were vaccinated, and 98.2% (n = 383) underwent antiviral treatment. Long-COVID prevalence was observed at 77.7%, with the most frequently reported symptoms being fatigue (64.1%) and cough (43.9%). Regarding mental health, depression was reported by 8.2% of the participants, anxiety by 4.1%, and poor sleep quality by 33.3%. Advanced statistical analysis using multivariable logistic regression showed significant links between long-COVID symptoms and patients aged below 60 (p = 0.042), as well as the initial symptom of cough (p = 0.045). In the subset of long-COVID sufferers, there was a notable correlation in females with symptoms such as headaches (p = 0.001), dizziness (p = 0.007), and brain fog (p = 0.013). Conclusions: Despite the extensive distribution of vaccines and antiviral therapies, the prevalence of long COVID remains high, being associated particularly with individuals under 60 and those exhibiting a cough as an early symptom. The study further reveals that mental health issues related to long COVID are profound, going beyond the scope of physical symptomatology.

Abstract
(1) Background: Early identification of severe coronavirus disease 2019 (COVID-19) pneumonia at the initial phase of hospitalization is very crucial. To address this, we validated and updated the National Early Warning Score 2 (NEWS2) for this purpose. (2) Methods: We conducted a study on adult patients with COVID-19 infection in Chiang Mai, Thailand, between May 2021 and October 2021. (3) Results: From a total of 725 COVID-19 adult patients, 350 (48.3%) patients suffered severe COVID-19 pneumonia. In determining severe COVID-19 pneumonia, NEWS2 and NEWS2 + Age + BMI (NEWS2 Plus) showed the C-statistic values of 0.798 (95% CI, 0.767-0.830) and 0.821 (95% CI, 0.791-0.850), respectively. The C-statistic values of NEWS2 Plus were significantly improved compared to those of NEWS2 alone (p = 0.012). Utilizing a cut-off point of five, NEWS2 Plus exhibited better sensitivity and negative predictive value than the traditional NEWS2, with values of 99.7% vs. 83.7% and 98.9% vs. 80.7%, respectively. (4) Conclusions: The incorporation of age and BMI into the traditional NEWS2 score enhanced the efficacy of determining severe COVID-19 pneumonia. Physicians can rely on NEWS2 Plus (NEWS2 + Age + BMI) as a more effective decision-making tool for triaging COVID-19 patients during early hospitalization.

Abstract
OBJECTIVE Short-acting β2-agonist (SABA) overuse is associated with poor asthma outcomes; however, the extent of SABA use in Thailand is largely unknown. As part of the SABA use IN Asthma (SABINA) III study, we describe asthma treatment patterns, including SABA prescriptions, in patients treated by specialists in Thailand. METHODS In this observational, cross-sectional study, patients (aged ≥12 years) with an asthma diagnosis were recruited by specialists from three Thai tertiary care centers using purposive sampling. Patients were classified by investigator-defined asthma severity (per 2017 Global Initiative for Asthma [GINA] recommendations). Data on sociodemographics, disease characteristics, and asthma treatment prescriptions were collected from existing medical records by healthcare providers and transcribed onto electronic case report forms. Analyses were descriptive. RESULTS All 385 analyzed patients (mean age: 57.6 years; 69.6% female) were treated by specialists. Almost all (91.2%) patients were classified with moderate-to-severe asthma (GINA treatment steps 3-5), 69.1% were overweight/obese, and 99.7% reported partially/fully reimbursed healthcare. Asthma was partly controlled/uncontrolled in 24.2% of patients; 23.1% experienced ≥1 severe asthma exacerbation in the preceding 12 months. Overall, SABAs were over-prescribed (≥3 canisters/year) in 28.3% of patients. Inhaled corticosteroids (ICS), ICS/long-acting β2-agonists, oral corticosteroid (OCS) burst treatment, and long-term OCS were prescribed to 7.0, 93.2, 19.2, and 6.2% of patients, respectively. Additionally, 4.2% of patients reported purchasing SABA over the counter. CONCLUSIONS Despite receiving specialist treatment, 28.3% of patients were over-prescribed to SABA in the previous 12 months, highlighting a public health concern and the need to align clinical practices with current evidence-based recommendations.

Abstract
INTRODUCTION Severe COVID-19 pneumonia can activate a cytokine storm. Hemoperfusion can reduce pro-inflammatory cytokines in sepsis but is still debated in the COVID-19 setting. Thus, we sought to investigate the benefits of HA-330 cytokine adsorption through clinical and laboratory outcomes. METHODS We conducted a single-center prospective observational study in adults with severe COVID-19 pneumonia admitted to the intensive care unit at Chiang Mai University Hospital (Chiang Mai, Thailand). Those with cytokine storms indicated by organ injury, including acute respiratory distress syndrome (ARDS), and high inflammatory markers were included. Patients treated with the HA-330 device were classified as a hemoperfusion group, while those without cytokine adsorption were classified as a control group. We compared the outcomes on day 7 after treatment and evaluated the factors associated with 60-day mortality. RESULTS A total of 112 patients were enrolled. Thirty-eight patients received hemoperfusion, while 74 patients did not. Baseline cytokine storm parameters were comparable. In univariate analysis, there was an improvement in clinical and laboratory effects from hemoperfusion therapy. In multivariate analysis, APACHE II score, SOFA score, PaO2/FiO2, the number of hemoperfusion sessions, the amount of blood purified, high-sensitivity C-reactive protein, and IL-6 were associated with mortality. Using at least 3 sessions of hemoperfusion could mitigate, the 60-day mortality (adjusted odds ratio 0.25, 95% confidence interval: 0.03-0.33, p = 0.001). By categorizing the amount of blood treated into 3 groups of <1 L/kg, 1-2 L/kg, and ≥2 L/kg, there was a linear dose-response association with survival, which was better in the higher volume purified (mortality 60% vs. 33.3% vs. 0%, respectively, p = 0.015). CONCLUSIONS The early initiation of HA-330 hemoperfusion could improve the severity score and laboratory outcomes of COVID-19 ARDS. The optimal dose of at least three sessions or the amount of blood purified greater than 1 L/kg was associated with a reduction in 60-day mortality.

Abstract
AIM To date, no studies representing the Southeast Asian population have validated the Pulmonary Embolism Severity Index (PESI) and 2019 European Society of Cardiology (ESC) risk stratification. Therefore, this study aimed to validate the PESI score, simplified PESI (sPESI), PESI risk classification, and 2019 ESC risk stratification in Southeast Asian patients with acute pulmonary embolism (APE). METHODS The present study is a 10-year cross-sectional study. Here, risk regressions were conducted to identify the PESI risk classification, sPESI, and 2019 ESC risk stratification as predictors for 30-day all-cause and PE-related mortalities. Receiver operating characteristic (ROC) curves were constructed to determine the diagnostic ability of the PESI score, sPESI score, PESI risk classification, and 2019 ESC risk stratification to predict 30-day mortality. RESULTS A total of 696 patients (male, 286; female, 410; mean age, 57.7±15.7 years) were included in this study from 2011 to 2020. The risk of 30-day all-cause mortality progressively increased with the 2019 ESC risk stratification, being approximately 6-fold higher in the high-risk than in the low-risk class [risk ratio: 6.24 (95% confidence interval (CI), 3.12, 12.47), P<0.001]. The risk of 30-day all-cause mortality with the PESI risk classification also increased with the risk classes, being approximately 6-fold higher in class V than in class I [adjusted risk ratio: 5.91 (95% CI, 2.25, 15.51), P<0.001]. The highest area under the receiver operating characteristic curve (AuROC) of the predictive model was the PESI score [AuROC=0.733 (95% CI, 0.685, 0.782)]. CONCLUSION Our study represents a good validation of the PESI and 2019 ESC risk stratification to predict 30-day mortality after APE diagnosis in the Southeast Asian population.

Abstract
Background The extent of short-acting Beta-2-agonist (β2-agonist) (SABA) use across Asian countries is not well documented. As part of the SABA use IN Asthma (SABINA) III study, we assessed SABA prescriptions and clinical outcomes in patients with asthma from Asia. Methods This cross-sectional study recruited patients (aged ≥12 years) with asthma from 8 Asian countries. Data on disease characteristics and asthma treatments were collected using electronic case report forms. Patients were classified by practice type (primary or specialist care) and investigator-defined asthma severity (per Global Initiative for Asthma [GINA] 2017 recommendations). The association of SABA prescriptions with clinical outcomes was analyzed using multivariable regression models. Results Overall, 3066 patients were analyzed, with a mean (standard deviation) age of 51.8 (16.7) years; of these patients, 2116 (69%) were female, 2517 (82.1%) had moderate-to-severe asthma and 2498 (81.5%) and 559 (18.2%) were treated in specialist and primary care, respectively. In total, 1423 (46.4%) patients had partly controlled/uncontrolled asthma, with 1149 (37.5%) patients experiencing ≥1 severe asthma exacerbation in the previous year. Overall, 800 (26.7%) patients were prescribed ≥3 SABA canisters in the previous year, which is regarded as overprescription and was associated with a significantly decreased odds of at least partly controlled asthma and increased incidence rates of severe exacerbations (P < 0.01 for both associations). Conclusion The findings from this cohort of predominantly specialist-treated patients with asthma indicate SABA overprescription in at least 1 in every 4 patients, and this overprescription is associated with poor clinical outcomes. These data highlight the need for adherence to recently updated asthma treatment recommendations in Asia.

Abstract
Background The sequelae of post-coronavirus disease 2019 (COVID-19) have been widely reported. However, the time point of the follow-up time in the previous studies varied ranging from 3-24 months and the interval time of the follow-up time was too long (6 or 12 months). Thus, a shorter interval time during recovery for assessment of the sequelae of post COVID-19 on lung function and exercise capacity is still required. Therefore, this study aims to explore the long-term impact of COVID-19 pneumonia on pulmonary function and exercise capacity. Methods A prospective observational study was conducted on post COVID-19 pneumonia at the Lung Health Center, Division of Pulmonary, Critical Care and Allergy, Department of Internal Medicine, Faculty of Medicine, Chiang Mai University, Chiang Mai, Thailand between May 2021 and April 2022. Spirometry, impulse oscillometry (IOS), and fractional exhaled nitric oxide (FeNO) were assessed at 1-, 6-, 9-, and 12-month post-hospital discharge when compared to healthy controls. The six-minute walk test (6-MWT) was also assessed. Results Thirty-eight post COVID-19 pneumonia with ages 41.1±14.8 years (52.6% male) and twenty-five healthy controls were enrolled. The %predicted of forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1) were significantly lower in post COVID-19 pneumonia compared to healthy controls at month 1 and month 9. The improvement of %predicted FVC and FEV1 was observed in post COVID-19 pneumonia. The six-minute walk distance (6-MWD) was significantly lower in post COVID-19 pneumonia compared to healthy controls in all visits, while the 6-MWD improved overtime in post COVID-19 pneumonia. Conclusions The long term sequelae of post COVID-19 pneumonia on lung function and exercise capacity were observed. Pulmonary function tests and six-minutes walk test are useful tools for detection of long term sequelae of post COVID-19 pneumonia.

Abstract
BACKGROUND Data on humoral and cellular immune responses against SARS-CoV-2 after receiving heterologous CoronaVac/ChAdOx-1 (CoVac/ChAd) vaccination in subjects with chronic obstructive pulmonary disease (COPD) are still limited. Therefore, we determined the neutralizing antibody (NAb) and T-cell responses against SARS-CoV-2 wild type (WT) and variants of concern (VOCs) in COPD patients. METHODS The levels of NAb as well as specific CD4 and CD8 T-cell responses against SARS-CoV-2 WT and VOCs were determined in COPD patients before and after vaccination. RESULTS Four weeks after vaccinations, the median levels of % inhibition of NAb against SARS-CoV-2 WT, Alpha, Beta, and Delta variants were significantly higher compared to pre-vaccination. The induction of NAb against Omicron was very low compared to other variants. At four weeks after vaccination, in comparison to pre-vaccination, the increasing trend of TNF-α-, IFN-γ-, IL-4-, IL-17-, IL-10-, and FasL-producing CD4 T-cells upon stimulation with WT spike peptides were demonstrated. No difference in T-cell responses to spike peptides of Alpha, Beta, and Delta variants and their WT homologs was observed. CONCLUSION Heterologous CoVac/ChAd vaccine induced the production of NAb against SARS-CoV-2 WT, Alpha, Beta, and Delta variants, but low for Omicron in COPD patients. Induction of CD4 T-cell subset responses was slightly observed by this vaccine regimen. CLINICAL TRIALS REGISTRY This study was approved by the Clinical Trials Registry (Study ID: TCTR20210822002).

Abstract
Many studies have demonstrated poor quality of life (QoL) at 3, 6, 12, and 24 months after coronavirus disease 2019 (COVID-19). However, these studies were limited due to cross-sectional design, a longer gap between visits, and lack of controls for comparison. Therefore, the aim of our prospective study was to assess the impact of COVID-19 pneumonia on QoL in both physical and mental health. A prospective study was conducted on adult patients with COVID-19 pneumonia. We used the 36-Item Short Form Health Survey (SF-36) and Euro Quality of Life-5 Dimensions-5 Levels (EQ-5D-5L), EQ visual analogue scale (EQ-VAS), and Hospital Anxiety and Depression Scale to collect data at months, 1, 3, 6, 9, and 12. Thirty-eight patients with COVID-19 pneumonia and twenty-five healthy subjects were completely followed up on all visits. All domains of SF-36, except bodily pain and EQ-5D-5L of the patients, were lower than controls. There was an improvement of EQ-VAS and SF-36 including physical functioning, social functioning, and role limitation (physical problems) domains throughout study period in the COVID-19 pneumonia group. Adult patients who recovered from COVID-19 pneumonia had lower QoL which improved over the one-year follow-up period.

Abstract
Background Continuous positive airway pressure (CPAP) is the most effective treatment for symptomatic obstructive sleep apnea (OSA). The identification of actual predictors of CPAP adherence in real-world practice is essential since it enhances more individualized management for the patient. CPAP acceptance and adherence in elderly patients with OSA have the same challenges but the conclusion remains unclear. Therefore, our aim was to explore the factors influencing the adherence of CPAP in elderly OSA patients. Methods The retrospective observational study was conducted from OSA patients' computerized medical records at Sleep Disorders Center, Center of Medical Excellence, Chiang Mai University Hospital, Chiang Mai, Thailand between 2018 and 2020. Multivariable risk regression analyses were performed to evaluate the independent factors associated with CPAP non-acceptance and CPAP non-adherence. Results Of the 1,070 patients who underwent overnight polysomnography (PSG), 336 (31.4%) were elderly. Of 759 patients who accepted CPAP treatment, 221 (29.1%) were elderly, including 27 (12.2%) non-adherences, 139 (62.9%) adherences and 55 (24.8%) loss follow-up. Elderly patients with adverse attitudes toward CPAP use affected adherence to treatment [adjusted risk ratio (RR) =4.59, 95% CI: 1.79, 11.78, P=0.002]. Female was also associated with low CPAP adherence with adjusted RR =3.10 (95% CI: 1.07, 9.01), P=0.037. Conclusions In our largest cohort to date, elderly OSA patients treated with CPAP over long-term follow-ups demonstrated that adherence rates were associated with personal life issues and adverse attitudes towards treatment as well as health problems. Female was also associated with low CPAP adherence. Therefore, in the elderly with OSA, the indication and treatment of CPAP should be customized individually, and if prescribed, regular monitoring to address noncompliance and tolerance should be considered.

Abstract
The outbreak of the SARS-CoV-2 Omicron variant raised the need for vaccine boosting. We evaluated the efficiency of the third booster vaccine, ChAdOx-1 or BNT162b2, in causing a neutralizing antibody (NAb) response and its durability against the Omicron and other variants in elderly individuals previously vaccinated with 2-dose CoronaVac inactivated vaccine. After receiving 2-dose CoronaVac, only 2.2% of subjects had NAbs against the Omicron variant above the cut-off value. Four weeks after boosting, the number of subjects who had NAb levels above the cut-off values in the ChAdOx-1 and BNT162b2 vaccine boosting groups increased to 41.7% and 54.5%, respectively. However, after 12 and 24 weeks of boosting with any vaccines, NAb levels against the Omicron variant dramatically waned. Twenty-four weeks after boosting, only 2% had high levels of NAbs against the Omicron variant. Compared to other variants, the Omicron variant was less responsive to boosting vaccines. The waning rate of NAb levels for the Omicron variant was much faster than that observed in the Alpha, Beta and Delta variants. To combat the Omicron variant, the fourth booster dose is, therefore, recommended for elderly individuals.

Abstract
BACKGROUND The concept of heterologous vaccination against SARS-CoV-2 infection has been adopted in Thailand with limited data on the induction of humoral and cellular immunity, particularly the CoronaVac/ChAdOx-1 (CoVac/ChAd) regimen in the elderly. OBJECTIVE In this study, the immune responses of the elderly induced by heterologous CoVac/ChAd and homologous ChAdOx-1 (ChAd/ChAd) vaccinations were demonstrated. METHODS A prospective observational study involving healthy participants aged ≥ 60 years who received heterologous CoVac/ChAd or homologous ChAd/ChAd vaccination was conducted. Surrogate neutralizing antibody (NAb) and T-cell responses against the SARS-CoV-2 wild type (WT) and variants of concern were determined at pre and post vaccinations. RESULTS At 4 and 12 weeks after heterologous or homologous vaccination, the NAb levels against WT, Alpha, Beta, and Delta variants between each group were not significantly different, except for significant lower NAb against the Beta variant in heterologous group at 12 weeks after vaccination. The NAb against the Omicron at 4 weeks post-vaccination were below the cutoff level for antibody detection in both groups. However, higher spike-specific CD4 T cell producing IFN-γ and TNF-α in the heterologous than the homologous vaccination were observed. Insignificant difference of cellular immune responses to spike-peptides of Alpha, Beta, and Delta variants and their WT homologues was demonstrated. CONCLUSIONS In the elderly, heterologous CoVac/ChAd vaccination could induce NAb response against the WT and non-Omicron variants not different from the homologous ChAd/ChAd vaccination. Both regimens could not give adequate NAb of the Omicron strain. The heterologous vaccination, however, induced higher spike-specific Th1 cell response.

Abstract
BACKGROUND The relationship between the level of air pollution and acute pulmonary embolism (APE) has had inconsistent results. OBJECTIVE This study aimed to analyze the relationship between the high level of air pollution exposure and APE. METHODS A ten-year retrospective cohort, single-center study was performed on patients diagnosed with APE from October 2010 to December 2020. The association between air pollution and monthly APE case diagnosis was analyzed. RESULTS A total number of 696 patients was included. The effect of every 10 µg/m3 increment of particulate matters with an aerodynamic diameter < 10 µm (PM10) on total monthly APE cases (unprovoked PE and provoked PE) was increased significantly at lag 4, 5 and 6 months with adjusted RR (95% CI) of 1.06 (1.01, 1.12), p = 0.011, 1.07 (1.01, 1.13), p = 0.021 and 1.06 (1.01, 1.12), p = 0.030, respectively. Adjusted RR for APE was significantly increased for PM10 in the second tertile ((adjusted RR (95% CI) 1.76 (1.12, 2.77)), p = 0.014. CONCLUSIONS We conclude that PM10 is associated with an increased prevalence of APE cases. The policy for tighter control of air pollution in our country is needed to reduce the impact of air pollutants on people's health.

Abstract
Background and Objective: Bradycardia has been observed among patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is suspected to be associated with poorer outcomes. Heart rate (HR) fluctuation has been found to be correlated with a greater mortality rate in critically ill patients. The association of bradycardia and HR fluctuation with the outcome of severe coronavirus disease 2019 (COVID-19) patients has not been clarified. Therefore, we aimed to examine whether bradycardia and HR fluctuation correlated with poor outcomes in patients with severe COVID-19. Materials and Methods: We conducted a secondary analysis from a prospective data collection of patients admitted to the intensive care unit, between April and June 2021, at Chiang Mai University Hospital. Results: The results showed that 62 of 86 patients (72.1%) had bradycardia, defined by HR < 60 beats per minute (bpm). The number of patients with high HR fluctuation, defined as the difference in HR during admission ≥ 40 bpm, was greater among the bradycardia group than in the non-bradycardia group (70.9% vs. 14.7%, p = 0.015, respectively). The patients with bradycardia had greater levels of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). In addition, a greater proportion of patients with bradycardia received interleukin-6 inhibitors and hemoperfusion as a rescue therapy than those with non-bradycardia. After adjusting for age, gender, body mass index, CRP, and mechanical ventilator; bradycardia and the high HR fluctuation were significantly associated with a longer length of stay in the intensive care unit (ICU-LOS), with adjusted risk ratios of 2.67, 95% CI; 1.02, 6.94, p = 0.045 and 2.88, 95% CI; 1.22, 6.78, p = 0.016, respectively. Conclusion: We found that bradycardia and a high heart rate fluctuation were associated with a poorer ICU outcome in terms of longer ICU-LOS among the patients with severe COVID-19.

Abstract
Background The existence of SARS-CoV-2 variants of concern (VOCs) in association with evidence of breakthrough infections despite vaccination resulted in the need for vaccine boosting. In elderly individuals, information on the immunogenicity of booster vaccinations is limited. In countries where the CoronaVac inactivated vaccine is the primary vaccine, the appropriate boosting regimen is not clear. Immunologic studies of the effects of booster vaccination against VOCs, particularly Delta and Omicron, following CoronaVac in elderly individuals are helpful for policy makers. In this study, we determined the immune responses against VOCs following ChAdOx-1 or BNT162b2 boosting in elderly individuals previously immunized with CoronaVac. Results Before boosting, the median % inhibition of neutralizing antibodies (NAbs) against the wild-type (WT), Alpha, Beta, Delta and Omicron variants in the ChAdOx-1 and BNT162b2 groups was 52.8% vs. 53.4, 36.6% vs. 39.9, 5.2% vs. 13.7, 34.3% vs. 44.9, and 20.8% vs. 18.8%, respectively. After boosting with ChAdOx-1 or BNT162b2, the % inhibition of NAbs were increased to 97.3% vs. 97.4, 94.3% vs. 97.3%, 79.9 vs. 93.7, 95.5% vs. 97.5, and 26.9% vs. 31.9% for WT, Alpha, Beta, Delta and Omicron variants, respectively. Boosting with BNT162b2 induced significantly higher NAb levels than boosting with ChAdOx-1 against the Alpha, Beta and Delta variants but not the WT and Omicron variants. NAb levels against Omicron variant were not significantly different before and after boosting with ChAdOx-1 or BNT162b2. To evaluate T-cell responses, S peptides of the WT, Alpha, Beta and Delta variants were used to stimulate T cells. Upon stimulation, the expression of IL-17A in CD8 T cells was higher in the BNT162b2 group than in the ChAdOx-1 boosting group. However, IFN-γ production in CD4 and CD8 T cells did not significantly differ under all vaccination regimens. The expression of FasL in CD4 T cells, but not CD8 T cells, was higher in the BNT162b2-boosted group. Conclusion Boosting with either ChAdOx-1 or BNT162b2 in CoronaVac-primed healthy elderly individuals induced high NAb production against all examined VOCs except Omicron. BNT162b2 stimulated higher NAb and some T-cell responses than ChAdOx-1. Vaccine boosting is, therefore, recommended for elderly individuals previously immunized with CoronaVac.

Abstract
Background Pressurized metered-dose inhaler (pMDI) is the most commonly used inhaler devices in community hospitals in Thailand. However, the research work on large group demonstration training method in the use of pMDI and pMDI with spacer in cases of chronic obstructive pulmonary disease (COPD) is very limited. Therefore, this study aimed to evaluate the effectiveness of this training method in elderly with COPD patients. Methods This prospective cross-sectional study was conducted at COPD clinic, Chiang Dao Hospital, Chiang Mai, Thailand between June 2019 and July 2019. All patients being treated in the clinic were assessed for their inhalation technique and inspiratory flow. After the initial assessment, patients were given instructions regarding the correct inhalation technique of pMDI and pMDI with spacer devices through large group demonstration. One month later, inhalation techniques and inspiratory flow were re-assessed. Results A total of 104 COPD patients were included, mean age 70.9±8.3 years, 51 (49.0%) male. At their first visit, 75.0% of pMDI and 81.7% of pMDI with spacer users performed at least one essential step incorrectly. After receiving large group demonstration training, there was a statistically significant increase in all devices; 26.7% vs. 56.7%, P=0.001 for correct technique, 41.7% vs. 62.7%, P=0.026 for appropriate flow, and 11.7% vs. 36.7%, P=0.001 for correct technique and flow. Conclusions The provision of large group training significantly increases the correct use of inhalation techniques and inspiratory flow for pMDI and pMDI with spacer in elderly with COPD.

Abstract
PURPOSE Driving while drowsy is a major cause of traffic accidents globally. Recent technologies for detection and alarm within automobiles for this condition are limited by their reliability, practicality, cost, and lack of clinical validation. In this study, we developed an early drowsiness detection algorithm and device based on the "gold standard brain biophysiological signal" and facial expression digital data. METHODS The data were obtained from 10 participants. Artificial neural networks (ANN) were adopted as the model. Composite features of facial descriptors (ie, eye aspect ratio (EAR), mouth aspect ratio (MAR), face length (FL), and face width balance (FWB)) extracted from two-second video frames were investigated. RESULTS The ANN combined with the EAR and MAR features had the most sensitivity (70.12%) while the ANN combined with the EAR, MAR, and FL features had the most accuracy and specificity (60.76% and 58.71%, respectively). In addition, by applying the discrete Fourier transform (DFT) to the composite features, the ANN combined with the EAR and MAR features again had the highest sensitivity (72.25%), while the ANN combined with the EAR, MAR, and FL features had the highest accuracy and specificity (60.40% and 54.10%, respectively). CONCLUSION The ANN with DFT combined with the EAR, MAR, and FL offered the best performance. Our direct driver sleepiness detection system developed from the integration of biophysiological information and internal validation provides a valuable algorithm, specifically toward alertness level.

Abstract
Open burnings, agricultural and forest fires, are the major sources of particulate matters (PM) in Chiang Mai during dry season. We aim to determine the association of an increased daily PM (PM10, PM2.5) and daily non-accidental mortality and causes of death in Chiang Mai. The association between PM and daily non-accidental mortality including causes of death were analyzed using a generalized linear model with Poisson distribution. The results showed that PM10 and PM2.5 were associated with daily non-accidental mortality on different lag days (adjusted RR range from 1.009-1.018 and 1.016 for each 10 µg/m3 increment of PM10 and PM2.5, respectively). The causes of death associated with PM10, PM2.5 found on different lag days were chronic obstructive pulmonary disease (COPD), coronary artery disease (CAD), and sepsis. We concluded that PM10 and PM2.5 are associated with daily non-accidental mortality and causes of death were COPD, CAD, and sepsis.

Abstract
PurposeThe purpose is to assess the effectiveness of continuous positive airway pressure (CPAP) treatment on sleep quality, daytime sleepiness and daytime functioning among Thai obstructive sleep apnea (OSA) patients.Design/methodology/approachA repeated measures clinical intervention design was implemented. Participants were 50 patients first time diagnosed with OSA and prescribed CPAP treatment. The intervention composed of CPAP health education, and follow-up evaluation. Data on CPAP adherence were downloaded from Smartcards of the CPAP device. The Thai PSQI, ESS and FSAQ-10 questionnaires were administered at baseline, 1-month, and 3-months. Descriptive statistics and repeated measure analysis with multilevel mixed-effects modeling approach were used.FindingsThirty-nine participants completed the study. Approximately 53% (n = 25) and 71.1% (n = 27) of the patients adhered to CPAP treatment by the end of the 1- and 3-months, respectively. After controlling for patients’ adherence, at 1-month follow-up, the intervention improved quality of sleep (β = −2.65, 95% CI = −1.60, −4.13), daytime functioning (β = 3.24, 95% CI = 1.87, 4.61) and decreased daytime sleepiness (β = −3.29, 95% CI = −1.85, −4.73). At 3 months, the intervention still improved quality of sleep (β = −3.53, 95% CI = −2.05, −5.01), and daytime functioning (β = 4.34, 95% CI = 2.76, 5.92), and decreased daytime sleepiness (β = −4.82, 95% CI = −3.16, −6.49).Originality/valueAdherence to CPAP treatment is effective in improving sleep quality, daytime functioning and reducing daytime sleepiness. Patient-oriented strategies for enhancing CPAP adherence should be developed and implemented as a standard care in sleep clinics.

Abstract
OBJECTIVE To determine the reliability of the Thai version of International Physical Activity Questionnaire Short Form (IPAQ-SF) in Chronic Obstructive Pulmonary Disease (COPD) patients. METHODS A cross sectional study was carried out in COPD subjects at Chiang Dao hospital, Chiang Mai, Thailand in June and July 2019. COPD subjects were asked to complete the Thai version of the IPAQ-SF. Calculations for each level of activity were carried out separately (vigorous activity, moderate activity, walking, and sitting). This was carried out twice with an interval of four weeks between visits. The test-retest reliability of the IPAQ was assessed using the intraclass correlation (ICC) with a 95% confidence interval (CI). Cohen's kappa coefficient and percentage agreement were used to test the repeatability of the physical activity classification between the two visits. RESULTS Sixty COPD subjects (50% male), with a mean age of 71.2 ± 7.7 years were included. The least reliability was established for sitting time (ICC = 0.439; 95%CI; 0.212, 0.621, p-value < 0.001) and the greatest for the total physical activity (ICC = 0.837; 95%CI; 0.741, 0.899, p-value < 0.001). The Kappa statistic was 0.433 with a 95%CI; 0.237, 0.639, p-value < 0.001 and the percentage agreement of the physical activity classification between the two visits was 66.7%. CONCLUSION The test-retest reliability was adequate for vigorous activity and total physical activity. Although there are concerns about the agreement for classification of physical activity, the IPAQ-SF may be a useful if not definitive tool for assessing physical activity in COPD.

Abstract
Background Balance assessment is now recommended by clinical practice guidelines, specific tests have yet to be suggested. The Timed Up and Go (TUG) test is a simple measure of balance status and functional mobility. Nowadays, we need more data of an optimum cut off point of TUG time for detecting balance impairment in patients with chronic obstructive pulmonary disease (COPD). Thus the aim of this study was to evaluate the diagnostic ability relative to balance impairment of the TUG in subjects with COPD. Methods The cross-sectional study was conducted in stable COPD patient at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand from November 2015 to October 2017. Balance impairment test was measured using the Berg Balance Scale (BBS), a score of ≤45 indicates balance impairment. The TUG was evaluated using sensitivity, specificity, positive likelihood ratio (LR+), negative likelihood ratio (LR−), Youden’s index, and the area under receiver operating characteristic curve (AUROC) from various points of TUG to identify the optimum cut-off point for detecting balance impairment. Multivariable logistic regressions were performed to identify the optimum cut off point of TUG test time for prediction of balance impairment in COPD. Results One hundred and eighteen smoking related COPD subjects 86 (72.9% male) with a mean age of 73.5±8.1 years were included in this study. Univariable analysis showed that the AUROC of TUG test to indicate those who had impaired balance was 0.93 [95% confidence interval (CI): 0.88, 0.98]. A cut off point of TUG test time ≥12 seconds had sensitivity, specificity, LR+, LR−, Youden’s index, and AUROC of 95.8%, 90.4%, 10.01, 0.05, 86.2, and 0.93 for detecting balance impairment, respectively. Multivariable analysis identified the TUG test time ≥12 seconds was the best predictor of balance impairment in COPD patients with adjusted risk ratio (RR) of 25.2 (95% CI: 1.6, 312.0, P=0.021) and, the AUROC was 0.98 (95% CI; 0.96, 1.00). Conclusions Our study indicates the TUG test time ≥12 seconds has a high diagnostic ability for balance impairment prediction in COPD. The result supports a potential role for this simple test to be incorporated into routine COPD assessment to stratify patients’ balance.

Abstract
Purpose To examine reliability and validity of a Thai version of the Family Satisfaction with Intensive Care Unit (FS-ICU 24) questionnaire and use this survey in intensive care units (ICUs) in Thailand. Materials and methods The standard English FS-ICU questionnaire was translated into the Thai language using translation and culture adaptation guidelines. After reliability and validity testing, we consecutively surveyed the satisfaction of family members of ICU patients over 1 year. Adult family members of patients admitted to medical or surgical ICUs for 48 hours or more who had visited the patients at least once during the ICU stay were included. Results In all, 315 (95%) of 332 surveys were returned from family members. Cronbach's α of the Thai FS-ICU 24 questionnaire was 0.95. Factor analysis demonstrated good construct validity. The mean (±SD) of total satisfaction score, overall ICU care subscale, and decision-making subscale were 81.5 ± 14.3, 81.0 ± 15.6, and 82.0 ± 14.0. Items with the lowest scores were the waiting room atmosphere and the frequency of doctors communicating with family members about the patient's condition. The mean total satisfaction score tended to be higher in family members of survivors than in family members of nonsurvivors (81.9 ± 13.8 vs 77.7 ± 16.2, p value = 0.059). The overall satisfaction scores between medial ICU and surgical ICU were not significantly different. Conclusion The Thai version of FS-ICU questionnaire was found to have acceptable reliability and validity in a Thai population and can be used to drive improvements in ICU care.

Abstract
Background Chiang Dao is one of the districts in Chiang Mai, Thailand facing high level of seasonal air pollution every year, the exposure of community dwellers to outdoor air pollutants 24 hours a day during seasonal smog period because of their open-air housing style, and agricultural occupational hazard. In addition, Chiang Dao hospital is the only available hospital serving the community with open-air wards; therefore we could certainly to identify the association between air pollution and mortality of hospitalized patients. Thus, the aim of this study was to determine the association between daily average seasonal air pollutants and daily mortality of hospitalized patients and community dwellers as well as emergency and hospitalization visits for serious respiratory, cardiovascular, and cerebrovascular diseases. Methods This time series study was conducted between 1 March 2016 and 31 March 2017. The association of various air pollutant concentrations including particulate matter diameter less than 10 and 2.5 microns (PM10 and PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), ozone (O3) and daily mortality of hospitalized patients and community dwellers as well as relationship with frequencies of serious respiratory, cardiovascular, and cerebrovascular diseases were analyzed using a general linear model with Poisson distribution. Results Only PM2.5 was found to be associated with increased daily mortality of hospitalized patients (lag day 6, adjusted RR =1.153, 95% CI: 1.001-1.329), whereas PM10, PM2.5, NO2, and O3 were associated with increased daily non-accidental mortality of community dwellers (lag day 0-7, adjusted RR =1.006-1.040, 95% CI: 1.000-1.074). For acute serious respiratory events; PM10 and PM2.5 were associated with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), while SO2, CO, and O3 were associated with emergency visits for community-acquired pneumonia (CAP). O3 was associated with emergency visits for heart failure (HF), NO2 with emergency visits for myocardial infarction (MI), and SO2 with hospitalized visits for cerebrovascular accident (CVA). Conclusions Seasonal air pollutants were found to be associated with higher mortality among hospitalized patients and community dwellers with varying effects on severe acute respiratory, cardiovascular, and cerebrovascular diseases.

Abstract
Background and objective: Changing to a different spirometry reference equation can result in misinterpretation of spirometric findings. Currently, there is limited data about any discordance between the interpretations of airway obstruction (AO) using the Global Lungs Initiative (GLI) 2012 and the currently employed Thai reference equations (Siriraj) in Thai adults. Therefore, this study aimed to determine differences in diagnosis around AO and classification of the severity of AO using the GLI2012 and Siriraj reference equations in Thai adults. Materials and Methods: We analyzed spirometric results from Thai adults aged 40–80 years old (n = 2084), which were collected at the Lung Health Center, Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand between January 2005 and December 2015. The diagnoses concerning the AO were interpreted using the GLI2012 and Siriraj reference equations. The severity of AO in each case was classified into five grades, including mild, moderate, moderately severe, severe, or very severe. McNemar’s test was used to analyze differences in diagnosis of AO and classification of the level of severity. The Kappa statistic was used to determine agreements of diagnosis of AO and classification of severity between the two reference equations. Results: There were significant differences in both diagnosis of AO and their classifying severity level between the two reference equations (p-value < 0.001). However, the levels of agreement between the two reference equations were moderate to very good in different age and sex groups (Kappa values ranged from 0.62 to 0.78 for the diagnosis of AO and 0.54 to 0.89 for the classification of severity). Conclusions: Changing from the Siriraj to the GLI2012 reference equations underestimates the proportion of airway obstruction in Thai adults.

Abstract
OBJECTIVE The present study intended to determine the risk factors of severe exacerbation in chronic obstructive pulmonary disease patients even though managed by pulmonologists on a regular basis. MATERIAL AND METHOD A retrospective case-controlled study was conducted at the chest clinic, Maharaj Nakorn Chiang Mai Hospital from 1st August 2009 to 31st July 2010. The clinical relevant data for acute exacerbation (age, sex, co-morbidity, severity of COPD, COPD medication, annual influenza vaccination, compliance with inhaled drug use, chest radiographic abnormality, and long-term oxygen therapy) were compared between severe AECOPD and stable COPD patients by logistic regression analysis. RESULTS Out of 137 COPD patients, 17 (12.4%) had severe AECOPD with 29 episodes (21.2%). Six risk factors were identified, two modifiable and four non-modifiable. The two modifiable risk factors were annual influenza non-vaccination (odds ratio [OR] 27.79; 95% confidence interval [CI], 2.29-337.66, p-value = 0.01) and improper use of inhaled devices (OR 9.94, 95%CI 1.07-92.54, p-value = 0.04). The four non-modifiable risk factors were age <60 yrs (OR, 10.67; 95%CI, 1.92-59.31, p-value = 0.01), hypertension (OR, 4.03; 95%CI. 1.05-15.44, p-value = 0.04), enlarged pulmonary trunk as demonstrated by chest radiograph (OR, 8.61; 95%CI, 1.49-49.85, p-value = 0.02), and long-term oxygen therapy (OR, 7.09; 95%CI, 1.36-37.00, p-value = 0.02). CONCLUSION Six risk factors of severe AECOPD among patients whom were provided regularly managed by pulmonologists were identified; two of them, annual influenza non-vaccination and improper use of inhaled devices, could be potentially modified.

Abstract
OBJECTIVE To identify the prevalence, clinical characteristics, disease severity, and correlations of major chronic respiratory diseases (CRDs) among the adult population living in Chiang Mai. MATERIAL AND METHOD A cross-sectional study was conducted with adults living in municipal areas of Chiang Mai. All clinical relevant data collected by face-to-face interview was confirmed by pulmonologists. The chest radiographic findings and post-bronchodilator spirometry were done in all subjects. The aeroallergen skin test and rhinoscopy were performed in all chronic rhinitis and asthma subjects. RESULTS Five hundred seventy four subjects with mean age 52.9±10.0 years, 59.6% female, and 37.5% smokers were recruited. The prevalence of overall CRDs was 59.2%. Chronic rhinitis was the most prevalent chronic respiratory disease (n = 239, 41.6%), followed by asthma (n = 58, 10.1%), and chronic obstructive pulmonary disease (COPD) (n = 21, 3.7%). The most common abnormal pulmonary function test was restrictive lung disorders (n = 53, 9.6%). Asthma subjects were determined to be more allergic than chronic rhinitis subjects (58.1% vs. 39.9%, p-value = 0.033). Regarding the disease severity, 14.9% of chronic rhinitis and 10.3% of asthma subjects were classified as moderate to severe degree, whereas 81% of chronic obstructive pulmonary disease subjects were classified as moderate to very severe degrees. In asthma patients, there were positive association with chronic rhinitis (OR 3.9, 95% CI 2.1-7.0, p-value <0.001). CONCLUSION The prevalence of major CRDs in adults among Chiang Mai population was significantly high with overlapped respiratory symptoms and varying disease severity. Additionally, chronic rhinitis had correlation with asthma but not with COPD.

Abstract
OBJECTIVE To identify risk factors and clinical course of asthma with fixed airflow limitation. MATERIAL AND METHOD A retrospective case-control study of asthma patients was conducted over a 15-month period. Asthma with fixed airflow limitation patients were defined as chronic asthmatics who had both post-bronchodilator (BD) and on-treatment ratio of forced expiratory in first second (FEV1)/forced vital capacity (FVC) persistently less than 0.7, whereas usual chronic asthma patients had post-BD and/or on-treatment ratio of FEV1/FVC more than 0.7. Serial asthma control tests (ACT), medication used, exacerbations were assessed. The risk factors were analyzed using logistic regression. Clinical characteristics between groups were compared using Student’s t-test and Fisher’s exact test. RESULTS One hundred twenty from 142 eligible subjects were enrolled. They had asthma with fixed airflow limitation (n = 40) and usual chronic asthma (n = 80). Potential risk factors of asthma with fixed airflow limitation included early disease onset (age <15 years) [(adjusted odd ratio (OR) = 3.9, 95% confidence interval (CI) 1.9-8.3)] with longer disease duration (adjusted OR = 8.4, 95% CI 4.6-15.4 for >30 years). Asthma with fixed airflow limitation patients had lower ACT scores (p<0.001), lower level of asthma control (p<0.001), required more asthma medications (p = 0.002), and higher rates of hospitalization (p = 0.001) than usual chronic asthma. CONCLUSION The potential risk factors of asthma with fixed airflow limitation were earlier disease onset and longer disease duration. They had poorer asthma control, more medications needed, and higher rates of exacerbation than usual chronic asthma.

Abstract
OBJECTIVE Identify a correlation between body mass index (BMI) and fat-free mass index (FFMI) to clinical parameters in chronic obstructive pulmonary disease. MATERIAL AND METHOD The cross-sectional study was conducted at a single visit involving stable chronic obstructive pulmonary disease (COPD) patients at the outpatient chest clinic of the Chiang Mai University Hospital, Thailand. Eligible patients were evaluated for BMI, FFMI, lung function, modified medical research council (mMRC) dyspnea score, COPD assessment test (CAT) score, and number of acute exacerbation (AE) in the past year. The correlations of FFMI and BMI with other parameters were determined using Pearson correlation coefficient analysis. Body composition was categorized into four groups, normal, semi-starvation, muscle atrophy/sarcopenia, and cachexia based on BMI and FFMI. Statistical significance was accepted at p-value < 0.05. RESULTS One hundred twenty one stable COPD patients met study inclusion criteria. The FFMI showed a strong correlation with BMI (r = 0.792, p < 0.001). The FFMI, but not BMI, was significantly correlated with mMRC, precentage ofp redicted forced expiratory volume in first second (FEV₁), and CAT score (r = -0.315, 0.214, and -0.278, respectively). Body composition was categorized into four groups: normal body composition (n = 62, 51.2%), semi-starvation (n = 4, 3.3%), sarcopenia/ muscular atrophy (n = 12, 9.9%), and cachexia (n = 43, 35.5%). CONCLUSION FFMI, but not BMI, was significantly correlated with dyspnea severity, lung function, and quality of life. Body composition category assignment is a useful clinical tool.

Abstract
BACKGROUND Positive airway pressure (PAP) in subjects with both obstructive sleep apnea and COPD reduces the risk of pulmonary hypertension, death, and hospitalizations from COPD exacerbations, but adherence to the intervention is low, similar to the experience with noninvasive ventilation in stable COPD. We sought to assess whether hyperinflation on chest radiographs contributes to low adherence to PAP therapy in the overlap syndrome. METHODS Records of patients with a listed diagnosis of COPD at the time of polysomnography were reviewed. Overlap syndrome was diagnosed when COPD was clinically confirmed with spirometry showing a fixed airway obstruction and when the apnea-hypopnea index was ≥ 5. Hyperinflation was evaluated by a review of the right diaphragm height on a lateral chest radiograph. Adherence was assessed clinically or through device download at a 3-month follow-up, and later adherence was assessed by telephone interviews. A receiver operating curve was used to determine whether diaphragm height was associated with adherence. RESULTS Twenty-one of 41 subjects (51%) were considered adherent to PAP therapy at the 3-month visit. Adherent subjects were more overweight compared with non-adherent subjects (body mass index of 36.0 ± 5.7 vs 32.0 ± 5.7 kg/m(2), P = .03), sleepier at the onset (Epworth sleepiness scale score of 13.0 ± 5.8 vs 9.4 ± 5.4, P < .05), and less likely to have hyperinflation as defined by a right diaphragm height ≤ 2.45 cm (33% vs 65%, P = .04). The body mass index and initial sleepiness no longer predicted adherence beyond 3 months, but 35% of subjects with a right diaphragm height ≤ 2.45 cm were adherent beyond 3 months compared with 75% of those with a right diaphragm height > 2.45 cm (P = .04 by Fisher exact test). CONCLUSIONS Hyperinflation is associated with decreased adherence to PAP therapy in the overlap syndrome.

Abstract
BACKGROUND There are limited studies directly comparing correlation and agreement between peak expiratory flow rate (PEFR) and forced expiratory volume in 1 second (FEV1) for severity classification of COPD. However, clarifying the role of PEFR as a surrogate of COPD severity classification instead of FEV1 is essential in situations and areas where spirometry is not routinely available. PURPOSE To evaluate the agreement between FEV1 and PEFR using Global initiative for chronic Obstructive Lung Disease (GOLD) severity classification criteria. MATERIALS AND METHODS This cross-sectional study included stable COPD patients. Both absolute values and % predicted FEV1 and % predicted PEFR were obtained from the same patients at a single visit. The severity of COPD was classified according to GOLD criteria. Pearson's correlation coefficient was used to examine the relationship between FEV1 and PEFR. The agreement of % predicted FEV1 and % predicted PEFR in assigning severity categories was calculated using Kappa statistic, and identification of the limits of agreement was by Bland-Altman analysis. Statistical significance was set at P-value <0.05. RESULTS Three hundred stable COPD patients were enrolled; 195 (65.0%) male, mean age 70.4±9.4 years, and mean % predicted FEV1 51.4±20.1. Both correlations between the % predicted FEV1 and PEFR as well as the absolute values were strongly significant (r=0.76, P<0.001 and r=0.87, P<0.001, respectively). However, severity categories of airflow limitation based on % predicted FEV1 or PEFR intervals were concordant in only 179 patients (59.7%). The Kappa statistic for agreement was 0.41 (95% confidence interval, 0.34-0.48), suggesting unsatisfied agreement. The calculated limits of agreement were wide (+27.1% to -28.9%). CONCLUSION Although the correlation between FEV1 and PEFR measurements were strongly significant, the agreement between the two tests was unsatisfied and may influence inappropriate clinical decision making in diagnosis, severity classification, and management of COPD.

Abstract
Ventilator-associated pneumonia (VAP) caused by Acinetobacter baumannii remains a significant cause of morbidity and mortality. Increasing antimicrobial resistance influences the selection of antibiotic treatment especially pandrug-resistant A. baumannii. A retrospective cohort study was conducted in the Medical Intensive Care Unit to identify the risk factors of VAP caused by multidrug-resistant A. baumannii (MDR-AB), extensively drug-resistant A. baumannii (XDR-AB) and pandrug-resistant A. baumannii (PDR-AB). All 337 adult patients with confirmed A. baumannii VAP were included. The incidence of MDR-AB, XDR-AB and PDR-AB were 72 (21.4%), 220 (65.3%) and 12 (3.6%), respectively. The risk factor for MDR-AB was prior use of carbapenems (OR 5.20; 95% CI 1.41-19.17). Risk factors for XDR-AB were the prior use of carbapenems (OR, 6.30; 95% CI, 1.80-21.97) and a high Sequential Organ Failure Assessment (SOFA) score (OR 1.35; 95% CI 1.07-1.71). In PDR-AB, the risk factors were the prior use of colistin (OR, 155.95; 95% CI, 8.00-3041.98), carbapenems (OR, 12.84; 95% CI, 1.60-103.20) and a high Simplified Acute Physiology Score (SAPS II) (OR 1.10; 95% CI 1.01-1.22). In conclusion, previous exposure to antibiotics and severity of VAP were risk factors of drug-resistant A. baumannii. Judicious use of carbapenems and colistin is recommended to prevent the antimicrobial-resistant strains of this organism.

Abstract
Background Care for many chronic health conditions is delivered by both specialists and generalists. Differences in patients’ quality of care and management between generalists and specialists have been well documented for asthma, whereas a few studies for COPD reported no differences. Objective The objective of this study is to compare consistency with Global initiative for chronic Obstructive Lung Disease guidelines, as well as rate, health care utilization, and hospital outcomes of severe acute exacerbation (AE) of COPD patients managed by pulmonologists and internists. Materials and methods This is a 12-month prospective, comparative observational study among 208 COPD patients who were regularly managed by pulmonologists (Group A) and internists (Group B). Clinical data, health care utilization, and hospital outcomes of the two groups were statistically compared. Results Out of 208 enrolled patients, 137 (Group A) and 71 (Group B) were managed by pulmonologists and internists, respectively. Pharmacological treatment corresponding to disease severity stages between the two groups was not statistically different. Group A received care consistent with guidelines in terms of annual influenza vaccination (31.4% vs 9.9%, P<0.001) and pulmonary rehabilitation (24.1% vs 0%, P<0.001) greater than Group B. Group A had reduced rates (12.4% vs 23.9%, P=0.033) and numbers of severe AE (0.20±0.63 person-years vs 0.41±0.80 person-years, P=0.029). Among patients with severe AE requiring mechanical ventilation, Group A had reduced mechanical ventilator duration (1.5 [1–7] days vs 5 [3–29] days, P=0.005), hospital length of stay (3.5 [1–20] days vs 16 [6–29] days, P=0.012), and total hospital cost ($863 [247–2,496] vs $2,095 [763–6,792], P=0.049) as compared with Group B. Conclusion This study demonstrated that pulmonologists followed national COPD guidelines more closely than internists. The rates and frequencies of severe AE were significantly lower in patients managed by pulmonologists, and length of hospital stay and cost were significantly lower among the patients with severe AE who required mechanical ventilation.

Abstract
Background Chronic obstructive pulmonary disease (COPD) patients living in many countries are familiar with local dialects rather than the official language. We, therefore, compare the reliability and validity of the COPD Assessment Test (CAT) in Thai and northern Thai dialect versions, in stable COPD patients living in the northern part of Thailand. Methods A total of 160 COPD patients were randomly selected for the evaluation of each dialect version of CAT (n=80). The internal consistency of all eight items and test–retest reliability were investigated by using Cronbach’s alpha coefficient and intraclass correlation coefficient (ICCC), respectively. The validity was evaluated by the degree of correlation with St George’s Respiratory Questionnaire (SGRQ) using Pearson’s correlation. The correlations of CAT with clinical parameters such as forced expiratory volume in the first second (FEV1), modified Medical Research Council scale (mMRC) dyspnea score, and 6-minute walk distance (6-MWD) were also evaluated. Results The two versions of CAT showed high internal consistency reliability (Cronbach’s alpha coefficient of 0.82 and 0.76) as well as a high test–retest reliability (ICCC of 0.82 and 0.84) for Thai and northern Thai dialect versions, respectively. The test results revealed that the northern Thai dialect version had good correlation with SGRQ whereas the Thai version correlated only moderately. Conclusion The two Thai versions of CAT were proven to be good clinical tools with high reliability and acceptable validity for assessing the quality of life of Thai COPD patients. However, the northern Thai dialect version is more suitable for evaluating COPD patients living in the northern part of Thailand.

Abstract
Background The Chronic Obstructive Pulmonary Disease Assessment Test (CAT) could play a role in detecting acute deterioration in health status during monitoring visits in routine clinical practice. Objective To evaluate the discriminative property of a change in CAT score from a stable baseline visit for detecting acute deterioration in health status visits of chronic obstructive pulmonary disease (COPD) patients. Methods The CAT questionnaire was administered to stable COPD patients routinely attending the chest clinic of Chiang Mai University Hospital who were monitored using the CAT score every 1–3 months for 15 months. Acute deterioration in health status was defined as worsening or exacerbation. CAT scores at baseline, and subsequent visits with acute deterioration in health status were analyzed using the t-test. The receiver operating characteristic curve was performed to evaluate the discriminative property of change in CAT score for detecting acute deterioration during a health status visit. Results A total of 354 follow-up visits were made by 140 patients, aged 71.1±8.4 years, with a forced expiratory volume in 1 second of 47.49%±18.2% predicted, who were monitored for 15 months. The mean CAT score change between stable baseline visits, by patients’ and physicians’ global assessments, were 0.05 (95% confidence interval [CI], −0.37–0.46) and 0.18 (95% CI, −0.23–0.60), respectively. At worsening visits, as assessed by patients, there was significant increase in CAT score (6.07; 95% CI, 4.95–7.19). There were also significant increases in CAT scores at visits with mild and moderate exacerbation (5.51 [95% CI, 4.39–6.63] and 8.84 [95% CI, 6.29–11.39], respectively), as assessed by physicians. The area under the receiver operating characteristic curve of CAT score change for the detection of acute deterioration in health status was 0.89 (95% CI, 0.84–0.94), and the optimum cut-off point score was at 4, with a sensitivity, specificity, and accuracy of 76.8%, 83.6%, and 82.4%, respectively. Conclusions Change in CAT score during monitoring visits is useful for detecting acute deterioration in health status, and a change of 4 units could make a moderate prediction of acute deterioration in health status.

Abstract
Background Exercise training has been incorporated into the international guidelines for the treatment of chronic obstructive pulmonary disease (COPD). However, the long-term efficacy of the training program for patients with advanced COPD has never been evaluated in Thailand. Purpose To determine the long-term efficacy of intensive cycle ergometer exercise program on various clinical parameters of patients with advanced COPD. Materials and methods The patients with advanced COPD were separated into two groups: the intensive ergometer exercise program group and the control group. The clinical parameters of all the patients were assessed at baseline, every month for the first 3 months, and then every 3 months until they had completed the 24-month follow-up. Mann–Whitney U test was used to compare baseline mean differences between the groups. Repeated measure analysis was applied to determine the progress in all parameters during the entire follow-up period. Mean incase imputation method was applied to estimate the parameters of dropout cases. Results A total of 41 patients were enrolled: 27 in the intensive ergometer exercise program group and 14 in the control group. The intensive cycle ergometer exercise program group showed statistically significant improvements in muscle strength (from month 1 till the end of the study, month 24), endurance time (from month 1 till the end of measurement, month 12) and clinically significant improvements in 6-minute walk distance (from month 2 until month 9), dyspnea severity by transitional dyspnea index (from month 1 till the end of the study, month 24), and quality of life (from month 1 till the end of the study, month 24). There was no significant difference in survival rates between the groups. Conclusion The intensive ergometer exercise training program revealed meaningful long-term improvements in various clinical parameters for up to 2 years. These promising results should encourage health care professionals to promote exercise training for patients with advanced COPD who have limited daily activities despite optimal medication control.

Abstract
OBJECTIVE To assess the baseline clinical characteristics, management, and long-term survival of hospital-based COPD patients in the northern part of Thailand. MATERIAL AND METHOD One hundred and ninety five hospital-based COPD patients from community and provincial hospitals in the northern part of Thailand were recruited between May and November 2002. They were followed up for 45 months for survival. RESULTS Most of them (71.3%) were in the advanced stage and 41.8% were undernourished. Only a small fraction of the advanced stage patients (25.7%) estimated their dyspnea severity correctly with the disease stages. The frequency of the exacerbations increases as the disease become more severe. Only 23.7% of the advanced stage patients had received regular bronchodilator therapy. No patients had received pulmonary rehabilitation and long-term oxygen therapy. The 45 months survival was 75.6% in all patients. The severe group with low BMI had significantly lower survival than the one with normal BMI (67.7% vs. 89.8%, p = 0.040). CONCLUSION Most COPD patients in the northern part of Thailand were in the advanced stage. They were commonly undernourished and exacerbated but still under treated according to standard treatment guidelines. BMI tends to influence the long-term survival of the advanced stage patients.

Abstract
OBJECTIVE To evaluate the efficacy of the protocol-directed weaning from a mechanical ventilator compared to physician-directed weaning. MATERIAL AND METHOD A comparative study between retrospective studies of physician-directed weaning as controls (N = 198) reviewed from July 2000 to July 2002 and the prospective studies of protocol-directed weaning as intervention (N = 196) enrolled from October 2002 to October 2003 in the medical ICU of Maharaj Nakorn Chiang Mai Hospital, tertiary care center of northern Thailand. Study results were concluded by Fisher's exact test. RESULTS Baseline characteristics data of both groups including sex, age, illness severity which demonstrated by APACHE II score and PaO2/FiO2 ratio, causes of respiratory failure and mode of mechanical ventilation used were similar. The duration of mechanical ventilation before weaning was 5.89 +/- 3.71 days in the protocol-directed group and 7.41 +/- 5.54 days in the physician-directed group (p < 0.05). Weaning duration in the protocol-directed group was significantly shorter than the physician-directed group (14.58 +/- 16. 98 hours VS 47.09 +/- 38.23 hours; p < 0.05). Kaplan-Meire analysis demonstrated that patients in the protocol-directed group had significantly shorter durations of mechanical ventilation compared to patients in the physician-directed group (p = 0.001, log-rank test). The ICU LOS was significantly shorter in the protocol-directed group (7.91 +/- 4.71 vs 11.53 +/- 7.80 days; p < 0.05). The 28 days mortality rate and the incidence of hospital acquired pneumonia seemed to be less in the protocol-directed group (4.60% vs 6.10% and 5.60% vs 10.10% consecutively) and reintubation rate seemed to be higher in the protocol-directed group (6.1% vs 4.5%) than the physician-directed group but differences were not significant (p > 0. 05). CONCLUSION Protocol-directed weaning proved to have more efficacy in weaning patients from a ventilator than physician-directed weaning in terms of weaning duration and ICU length of stay without a deteriorating effect to the patients.
