Long-COVID Prevalence and Its Association with Health Outcomes in the Post-Vaccine and Antiviral-Availability Era. J Clin Med 2024; 13:1208. [PMID: 38592016 PMCID: PMC10931928 DOI: 10.3390/jcm13051208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 02/07/2024] [Accepted: 02/10/2024] [Indexed: 04/10/2024] Open
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.

The National Early Warning Score 2 with Age and Body Mass Index (NEWS2 Plus) to Determine Patients with Severe COVID-19 Pneumonia. J Clin Med 2024; 13:298. [PMID: 38202305 PMCID: PMC10780151 DOI: 10.3390/jcm13010298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 12/08/2023] [Accepted: 12/28/2023] [Indexed: 01/12/2024] Open
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.

Validation of the Pulmonary Embolism Severity Index Risk Classification and the 2019 European Society of Cardiology Risk Stratification in the Southeast Asian Population with Acute Pulmonary Embolism. J Atheroscler Thromb 2023; 30:1601-1611. [PMID: 36967130 PMCID: PMC10627767 DOI: 10.5551/jat.64094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 02/02/2023] [Indexed: 06/18/2023] Open
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.

Neutralizing antibody and T-cell responses against SARS-CoV-2 variants by heterologous CoronaVac/ChAdOx-1 vaccination in elderly subjects with chronic obstructive pulmonary disease. Vaccine 2023; 41:5901-5909. [PMID: 37599143 DOI: 10.1016/j.vaccine.2023.08.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 08/10/2023] [Accepted: 08/14/2023] [Indexed: 08/22/2023]
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).

Levels and durability of neutralizing antibodies against SARS-CoV-2 Omicron and other variants after ChAdOx-1 or BNT162b2 booster in CoronaVac-primed elderly individuals. Heliyon 2023; 9:e15653. [PMID: 37095993 PMCID: PMC10116116 DOI: 10.1016/j.heliyon.2023.e15653] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 04/05/2023] [Accepted: 04/18/2023] [Indexed: 04/26/2023] Open
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.

Humoral and cellular immune responses against SARS-CoV-2 variants of concern induced by heterologous CoronaVac/ChAdOx-1 versus homologous ChAdOx-1 vaccination in the elderly. Asian Pac J Allergy Immunol 2023. [PMID: 36773278 DOI: 10.12932/ap-120822-1434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/12/2023]
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.

Blood Lactate Level and the Predictor of Death in Non-shock Septic Patients. Indian J Crit Care Med 2023; 27:93-100. [PMID: 36865504 PMCID: PMC9973057 DOI: 10.5005/jp-journals-10071-24404] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Accepted: 12/30/2022] [Indexed: 02/04/2023] Open
Abstract
Objective To evaluate the association of initial blood lactate with mortality and subsequent septic shock in non-shock septic patients. Materials and methods A retrospective cohort study was conducted at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai University, Muang, Chiang Mai, Thailand. Inclusion criteria included septic patients admitted to a non-critical medical ward and had initial serum lactate at the emergency department (ED). Shock and other causes of hyperlactatemia were excluded. Results A total of 448 admissions were included with median age [interquartile range (IQR)] of 71 (59, 87) years and 200 males (44.6%). Pneumonia was the most common cause of sepsis (47.5%). The median systemic inflammatory response syndrome (SIRS) and quick sequential organ failure assessment (qSOFA) scores were 3 (2, 3) and 1 (1, 2), respectively. The median initial blood lactate was 2.19 (1.45, 3.23) mmol/L. The high blood lactate (≥2 mmol/L) group; N = 248, had higher qSOFA and other predictive scores and had significantly higher 28 days mortality (31.9% vs 10.0%; p < 0.001) and subsequent 3 days septic shock (18.1% vs 5.0%; p < 0.001) than the normal blood lactate group; N = 200. A combination of blood lactate above or equal to 2 mmol/L plus the national early warning score (NEWS) above or equal to 7 showed the highest prediction of 28 days mortality with the area under receiver-operating characteristic curve (AUROC) of 0.70 [95% confidence interval (CI): 0.65-0.75]. Conclusions An initial blood lactate level above or equal to 2 mmol/L is associated with high mortality and subsequent septic shock among non-shock septic patients. The composite of blood lactate levels and other predictive scores yields better accuracy to predict mortality. How to cite this article Noparatkailas N, Inchai J, Deesomchok A.

Correlation of Air Pollution and Prevalence of Acute Pulmonary Embolism in Northern Thailand. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:12808. [PMID: 36232104 PMCID: PMC9566050 DOI: 10.3390/ijerph191912808] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 10/04/2022] [Accepted: 10/05/2022] [Indexed: 06/16/2023]
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.

Neutralizing antibody and T cell responses against SARS-CoV-2 variants of concern following ChAdOx-1 or BNT162b2 boosting in the elderly previously immunized with CoronaVac vaccine. Immun Ageing 2022; 19:24. [PMID: 35610643 PMCID: PMC9126751 DOI: 10.1186/s12979-022-00279-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Accepted: 05/07/2022] [Indexed: 12/16/2022]
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
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
OBJECTIVE To examine the peripheral monocyte to lymphocyte ratio (ML ratio) of patients with tuberculous (TB) pleuritis and the ML ratio changes after treatment. METHODS Clinical and laboratory information were collected from patients with lymphocytic exudative pleural effusion admitted to Chiang Mai University Hospital from 2013 to 2019. This study compared the ML ratios between tuberculous pleuritis and other diagnoses in patients who were followed after treatment. RESULTS A total of 152 patients were included: 57 with tuberculous pleuritis and 95 with other lymphocytic exudates. The majority of non-tuberculous effusion was malignant pleural effusion. The mean ML ratio of each group was 0.72±0.29 and 0.34±0.13 (p<0.001). The Area Under the Receiver Operative Characteristic Curve of the ML ratio for diagnosing tuberculous pleuritis was 0.91. The best cut-off point of the ML ratio for diagnosing tuberculous pleuritis was >0.45, where the sensitivity and specificity were 82.5% and 86.3%, respectively. The ML ratio gradually reduced after the anti-TB treatment. ML ratios at 0, 2, and 6 months after the treatment were 0.72±0.29, 0.40±0.37, and 0.30±0.27, respectively (p<0.001). CONCLUSION The peripheral blood ML ratio is an easy and useful tool for diagnosing and predicting the treatment response in patients with tuberculous pleuritis.

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
Tuberculosis (TB) among healthcare workers (HCWs) highly affects morbidity and TB transmission in hospitals. A retrospective cohort study of TB among HCWs (HCW-TB) was conducted using a registered database from 2003 to 2016 at Chiang Mai University Hospital to determine clinical and microbiological characteristics and treatment outcomes of HCW-TB. A total of 76 patients comprising 54 nurses (71.1%), 12 physicians (15.8%), and 10 paramedics (13.2%) were diagnosed with TB disease. The men to women ratio was 25:51, with a mean age of 37.0±11.6 years, a median work duration of 12.0 years (5-20) and a body mass index of 19.4±2.5 kg/m2. Within the HCW-TB group, 28 (36.8%) worked in the Medical Department, 12 (15.8%) worked in the Outpatient Department/Emergency Room, and 9 (11.8%) worked in the Surgical Department. Pulmonary TB (PTB) was the most common manifestation of HCW-TB (92.1%). Sputum acid-fast stains were positive among 28 (40.0%) HCWs with PTB. Mycobacterium tuberculosis cultures were positive in 26 (34.2%) patients. Drug susceptibility testing showed sensitivity to all first-line drugs (75.0%), resistance to any one first-line drug (20.8%), and multidrug-resistant TB comprised 4.2%. The end-of-treatment success rate was 100%. Therefore, TB control guidelines should be strictly implemented to prevent TB transmission in healthcare settings.

Abstract
BACKGROUND Seasonal smog produces particulate matters that are less than 10 microns in diameter (PM₁₀), which are known to have several impacts on the respiratory system. OBJECTIVE This study was to determine the association of an increased PM10 level due to seasonal smog in Chiang Mai and emergency visits for asthma and chronic obstructive pulmonary disease (COPD) exacerbations. METHOD A retrospective cross-sectional study was conducted between the months of January and March from 2006 until 2009. The association of an increased PM₁₀ level and the daily number of asthma and COPD exacerbations were analyzed using a generalized linear model; a Poisson regression model was fit to the number of daily emergency visits using predictor variables: lags of PM10, day of the week, and time. RESULTS There were a total of 917 emergency visits for acute exacerbations of asthma and COPD, with a median of 2 visits per day (range 0-10). The median PM₁₀ level during the same interval was 64.5 microgram per cubic meter (μg/m3) (16-304). For every 10 μg/m3 rise in PM10 concentration, there was a lag time of 6 days for asthma exacerbations [Adjusted relative risk (RR)=1.020; 95% confident interval (CI), 1.001-1.040; (p=0.014)], 7 days for COPD exacerbations [RR=1.030; 95%CI, 1.010-1.050 (p=0.024)] and 7 days for all exacerbations [RR=1.030 95%CI, 1.010-1.040 (p<0.001)]. CONCLUSIONS This study confirms the effect of increasing PM₁₀ concentrations from seasonal smog on asthma and COPD exacerbations. However, there was an approximately 1 week lag time between the elevated PM₁₀ levels and time to emergency visits due to disease exacerbation.

Abstract
Background Chronic obstructive pulmonary disease (COPD) and other chronic respiratory diseases (CRDs) have significant impacts on quality of life including psychomotor domain. Purpose To evaluate three major affective disorders in subjects with COPD compared with other CRDs and nonill population. Materials and methods The Thai version of Mini International Neuropsychiatric Interview (MINI) was used as a diagnostic instrument for three major affective disorders (generalized anxiety disorder, major depressive disorder, and panic disorder) by face-to-face interview in assessing patients with CRDs [COPD, asthma, rhinasthma, all asthma (asthma and rhinasthma), and chronic rhinitis], and nonill subjects. Logistic regression analyses were used to determine the relation between major affective disorders and CRDs adjusting for age, sex, and disease severity. Results Major affective disorders were more prevalent in CRDs than nonill groups (adjusted OR =2.6 [95% CI, 1.8−3.9], P<0.001). COPD patients had significantly more generalized anxiety and panic disorder (adjusted OR =4.0 [95% CI, 1.4−11.9], P=0.011, and 4.4 [95% CI, 1.1−18.1], P=0.038, respectively) but not major depressive disorder (adjusted OR =2.7 [95% CI, 0.8−9.0, P=0.105]) than nonill group. Comparing with all asthma, COPD patients had lower occurrence of major depressive and panic disorders (adjusted OR =0.1 [95% CI, 0.0−0.4], P=0.002, and 0.1 [95% CI, 0.0−0.9], P=0.043, respectively). There was no difference in major mood disorders in COPD, rhinasthma, and chronic rhinitis patients. Major affective disorders were not increased by disease severity in COPD. Conclusion Major affective disorders were significantly higher in CRDs than nonill population. Generalized anxiety and panic disorders were significantly high in COPD patients. Moreover, major depressive and panic disorders in COPD were significantly lower than all asthma. The prevalence of major affective disorders may not be related to severity of COPD.

Abstract
Background COPD prevalence and consequent burden are expected to rapidly increase worldwide. Until now, there has been no community-based study of COPD in Thailand. Purpose We aimed to compare the prevalence, clinical characteristics, disease severity, previous diagnosis, and management of COPD between urban and rural communities. Materials and methods A population-based cross-sectional study was designed to compare COPD prevalence and burden in rural and urban communities in Chiang Mai Province, Thailand. The COPD subjects were diagnosed and severity categories assigned using Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. The prevalence between the groups was compared using risk regression analysis. Unpaired t-test and chi-square were used to compare differences between the groups. Results There were 574 and 293 enrolled subjects with acceptable spirometry, in rural and urban communities respectively. The prevalence of COPD in general and COPD in females was higher in the rural group (6.8% vs 3.7% and 4.4% vs 0.9%, respectively) across all independent variables. However, after adjustment for age, sex, and smoking status, no significant differences were demonstrated. Although the pulmonary function and disease severity between the two groups were not significantly different, the tendency was more pronounced in the rural group (COPD stage III–IV: 65.0% vs 33.3%). Most of the COPD patients in both groups were underdiagnosed (80.0% vs 77.2%) and undertreated (85.0% vs 81.9%). None of the patients in the study had participated in exercise training programs. Conclusion The prevalence of COPD in general and particularly COPD in females tended to be higher, with more severe disease in the rural community. However, both groups were similarly underdiagnosed and undertreated.

Risk factors of multidrug-resistant, extensively drug-resistant and pandrug-resistant Acinetobacter baumannii ventilator-associated pneumonia in a Medical Intensive Care Unit of University Hospital in Thailand. J Infect Chemother 2015; 21:570-4. [PMID: 26026660 DOI: 10.1016/j.jiac.2015.04.010] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2014] [Revised: 04/22/2015] [Accepted: 04/23/2015] [Indexed: 12/23/2022]
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 Ventilator-associated pneumonia (VAP) caused by drug-resistant Acinetobacter baumannii is associated with high mortality in critically ill patients. We identified the prognostic factors of 30-day mortality in patients with VAP caused by drug-resistant A. baumannii and compared survival outcomes among multidrug-resistant (MDR), extensively drug-resistant (XDR) and pandrug-resistant (PDR) A. baumannii VAP. Methods A retrospective cohort study was conducted in the Medical Intensive Care Unit at Chiang Mai University Hospital, Thailand. All adult patients diagnosed with A. baumannii VAP between 2005 and 2011 were eligible. Univariable and multivariable Cox’s proportional hazards regression were performed to identify the prognostic factors of 30-day mortality. Results A total of 337 patients with microbiologically confirmed A. baumannii VAP were included. The proportion of drug-sensitive (DS), MDR, XDR, and PDR A. baumannii were 9.8%, 21.4%, 65.3%, and 3.6%, respectively. The 30-day mortality rates were 21.2%, 31.9%, 56.8%, and 66.7%, respectively. The independent prognostic factors were SOFA score >5 (hazard ratio (HR) = 3.33, 95% confidence interval (CI) 1.94–5.72, P < 0.001), presence of septic shock (HR = 2.66, 95% CI 1.71–4.12, P < 0.001), Simplified Acute Physiology Score (SAPS) II >45 (HR = 1.58, 95% CI 1.01–2.46, P = 0.045), and inappropriate initial antibiotic treatment (HR = 1.53, 95% CI 1.08–2.20, P = 0.016). Conclusions Drug-resistant A. baumannii, particularly XDR and PDR, was associated with a high mortality rate. Septic shock, high SAPS II, high SOFA score, and inappropriate initial antibiotic treatment were independent prognostic factors for 30-day mortality.

Abstract
We conducted a retrospective cohort study in the medical intensive care unit of Chaing Mai University Hospital to describe the epidemiology of ventilator-associated pneumonia (VAP) and identify prognostic indicators of 30-day VAP mortality. A total of 621 patients diagnosed with VAP between January 2005 and December 2011 were included. The overall 30-day mortality rate was 44.4%. The major causative pathogens were Acinetobacter baumannii (54.3%), Pseudomonas aeruginosa (35.2%), and methicillin-resistant Staphylococcus aureus (15.1%). Most A. baumannii (90.2%) comprised drug-resistant strains. Identified prognostic indicators were co-morbid malignancy (hazard ratio [HR] = 1.60; 95% confidence interval [CI] 1.02-2.42; P = 0.040), septic shock (HR = 2.51; 95% CI, 1.60-4.00; P < 0.001), Simplified Acute Physiology Score II >45 (HR = 1.62; 95% CI, 1.03-2.56; P = 0.041), Sequential Organ Failure Assessment score >5 (HR = 3.40; 95% CI 2.00-5.81; P < 0.001), and delayed inappropriate empirical antibiotic treatment (HR = 2.23; 95% CI, 1.12-4.45; P = 0.022). VAP was associated with high mortality. The major causative pathogen was drug-resistant A. baumannii. Therefore, early detection of VAP by surveillance in mechanically ventilated patients leading to earlier treatment may improve patient outcomes. Guidelines for prescribing appropriate empirical antibiotics to cover drug-resistant bacteria could be established using local epidemiological data.

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.
