  1. Predicting the risk of exacerbation in patients with chronic obstructive pulmonary disease using home telehealth measurement data
    Mohktar MS, Redmond SJ, Antoniades NC, Rochford PD, Pretto JJ, Basilakis J, et al.
    Artif Intell Med, 2015 Jan;63(1):51-9.
    PMID: 25704112 DOI: 10.1016/j.artmed.2014.12.003
    BACKGROUND: The use of telehealth technologies to remotely monitor patients suffering chronic diseases may enable preemptive treatment of worsening health conditions before a significant deterioration in the subject's health status occurs, requiring hospital admission.
    OBJECTIVE: The objective of this study was to develop and validate a classification algorithm for the early identification of patients, with a background of chronic obstructive pulmonary disease (COPD), who appear to be at high risk of an imminent exacerbation event. The algorithm attempts to predict the patient's condition one day in advance, based on a comparison of their current physiological measurements against the distribution of their measurements over the previous month.
    METHOD: The proposed algorithm, which uses a classification and regression tree (CART), has been validated using telehealth measurement data recorded from patients with moderate/severe COPD living at home. The data were collected from February 2007 to January 2008, using a telehealth home monitoring unit.
    RESULTS: The CART algorithm can classify home telehealth measurement data into either a 'low risk' or 'high risk' category with 71.8% accuracy, 80.4% specificity and 61.1% sensitivity. The algorithm was able to detect a 'high risk' condition one day prior to patients actually being observed as having a worsening in their COPD condition, as defined by symptom and medication records.
    CONCLUSION: The CART analyses have shown that features extracted from three types of physiological measurements; forced expiratory volume in 1s (FEV1), arterial oxygen saturation (SPO2) and weight have the most predictive power in stratifying the patients condition. This CART algorithm for early detection could trigger the initiation of timely treatment, thereby potentially reducing exacerbation severity and recovery time and improving the patient's health. This study highlights the potential usefulness of automated analysis of home telehealth data in the early detection of exacerbation events among COPD patients.

    Int J Chron Obstruct Pulmon Dis, 2014;9:493-8.
    PMID: 24868154 DOI: 10.2147/COPD.S56637
    BACKGROUND: Lack of awareness among ex-smokers on the benefits of sustaining smoking cessation may be the main cause of their smoking relapse. This study explored health-related quality of life (HRQoL) and hospital admission amongst chronic obstructive pulmonary disease (COPD) patients according to the duration of smoking cessation.
    MATERIALS AND METHODS: This study recruited COPD patients from a chest clinic who agreed to participate in a medication therapy-adherence program from January to June 2013. They were interviewed during their visits to obtain information regarding their smoking history and HRQoL. They were divided into three groups according to smoking status (sustained quitters, quit ≥5 years; quitters, quit <5 years; and smokers, smoking at least one cigarette/day). The effects of the duration of cessation on HRQoL and hospital admission were analyzed using a multinomial logistic model.
    RESULTS: A total of 117 participants with moderate COPD met the inclusion criteria, who were comprised of 41 sustained quitters, 40 quitters, and 36 smokers. Several features were similar across the groups. Most of them were married elderly men (aged >64 years) with low-to-middle level of education, who smoked more than 33 cigarettes per day and had high levels of adherence to the medication regimen. The results showed that sustained quitters were less likely to have respiratory symptoms (cough, phlegm and dyspnea) than smokers (odds ratio 0.02, confidence interval 0-0.12; P<0.001). The hospital admission rate per year was increased in quitters compared to smokers (odds ratio 4.5, confidence interval 1.91-10.59; P<0.005).
    CONCLUSION: A longer duration of quitting smoking will increase the benefits to COPD patients, even if they experience increased episodic respiratory symptoms in the early period of the cessation. Thus, the findings of this study show the benefits of early smoking cessation.

  4. Fulltext VitalQPlus: a potential screening tool for early diagnosis of COPD
    Sui CF, Ming LC, Neoh CF, Ibrahim B
    Int J Chron Obstruct Pulmon Dis, 2015;10:1613-22.
    PMID: 26316735 DOI: 10.2147/COPD.S84618
    Background: This study utilized a validated combination of a COPD Population Screener
    (COPD-PS) questionnaire and a handheld spirometric device as a screening tool for patients at high risk of COPD, such as smokers. The study aimed to investigate and pilot the feasibility and application of this combined assessment, which we termed the “VitalQPlus”, as a screening tool for the early detection of COPD, especially in primary care settings.
    Methods: This was a cross-sectional study screening potentially undiagnosed COPD patients using a validated five-item COPD-PS questionnaire together with a handheld spirometric device. Patients were recruited from selected Malaysian government primary care health centers.
    Results: Of the total of 83 final participants, only 24.1% (20/83) were recruited from Perak and Penang (peninsular Malaysia) compared to 75.9% (63/83) from Sabah (Borneo region). Our dual assessment approach identified 8.4% of the surveyed patients as having potentially undiagnosed COPD. When only the Vitalograph COPD-6 screening tool was used, 15.8% of patients were detected with a forced expiratory volume in 1 second/forced expiratory volume in 6 seconds (FEV1/FEV6) ratio at <0.75, while 35.9% of patients were detected with the COPD-PS questionnaire. These findings suggested that this dual assessment approach has a greater chance of identifying potentially undiagnosed COPD patients compared to the Vitalograph COPD-6 or COPD-PS questionnaire when used alone. Our findings show that patients with more symptoms (scores of >=5) yielded twice the percentage of outcomes of FEV1/FEV6 <0.75 compared to patients with fewer COPD symptoms (scores <5).
    Conclusion: With the availability of a simple screening questionnaire and the COPD-6, there is an opportunity easily to make patients more aware of their lung symptoms and to encourage the provision of early treatment. The proposed dual assessment approach, which we termed the VitalQPlus, may play a profound role in the early diagnosis of COPD, which is crucial in improving the clinical management of the disease.

  5. Fulltext Clinical phenotypes of COPD and health-related quality of life: a cross-sectional study
    Chai CS, Liam CK, Pang YK, Ng DL, Tan SB, Wong TS, et al.

    PMID: 30880946 DOI: 10.2147/COPD.S196109
    Introduction: The Spanish COPD guideline (GesEPOC) classifies COPD into four clinical phenotypes based on the exacerbation frequency and dominant clinical manifestations. In this study, we compared the disease-specific health-related quality of life (HRQoL) of patients with different clinical phenotypes.

    Methods: This was a cross-sectional study of patients with COPD attending the respiratory medicine clinic of University of Malaya Medical Centre from 1 June 2017 to 31 May 2018. Disease-specific HRQoL was assessed by using the COPD Assessment Test (CAT) and St George's Respiratory Questionnaire for COPD (SGRQ-c).

    Results: Of 189 patients, 28.6% were of non-exacerbator phenotype (NON-AE), 18.5% were of exacerbator with emphysema phenotype (AE NON-CB), 39.7% were of exacerbator with chronic bronchitis phenotype (AE CB), and 13.2% had asthma-COPD overlap syndrome phenotype (ACOS). The total CAT and SGRQ-c scores were significantly different between the clinical phenotypes (P<0.001). Patients who were AE CB had significantly higher total CAT score than those with ACOS (P=0.033), AE NON-CB (P=0.001), and NON-AE (P<0.001). Concerning SGRQ-c, patients who were AE CB also had a significantly higher total score than those with AE NON-CB (P=0.001) and NON-AE (P<0.001). However, the total SGRQ-c score of AE CB patients was only marginally higher than those who had ACOS (P=0.187). There was a significant difference in the score of each CAT item (except CAT 7) and SGRQ-c components between clinical phenotypes, with AE CB patients recording the highest score in each of them.

    Conclusion: Patients who were AE CB had significantly poorer HRQoL than other clinical phenotypes and recorded the worst score in each of the CAT items and SGRQ-c components. Therefore, AE CB patients may warrant a different treatment approach that focuses on the exacerbation and chronic bronchitis components.

  6. Fulltext Pulmonary function in symptom-free asthmatics
    Yaacob I, Mohammad M
    Singapore Med J, 1993 Dec;34(6):522-3.
    PMID: 8153715
    Seventy-five adult asthmatic patients with clinical remission underwent spirometry. Only 8.3% of the subjects demonstrated normal spirometry. The others had reduced vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximum mid-expiratory flow rate (MMF) and peak flow rate (PEFR). This study demonstrates that asthma can cause irreversible airflow obstruction and there is a poor relationship between symptoms in asthmatics and their respiratory function test results.

  7. Effects of indoor air pollution on lung function of primary school children in Kuala Lumpur
    Azizi BH, Henry RL
    Pediatr Pulmonol, 1990;9(1):24-9.
    PMID: 2388776
    In a cross-sectional study of 7-12 year-old primary school children in Kuala Lumpur city, lung function was assessed by spirometric and peak expiratory flow measurements. Spirometric and peak expiratory flow measurements were successfully performed in 1,214 and 1,414 children, respectively. As expected, the main predictors of forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory flow between 25% and 75% of vital capacity (FEF25-75), and peak expiratory flow rate (PEFR) were standing height, weight, age, and sex. In addition, lung function values of Chinese and Malays were generally higher than those of Indians. In multiple regression models which included host and environmental factors, asthma was associated with significant decreases in FEV1, FEF25-75, and PEFR. However, family history of chest illness, history of allergies, low paternal education, and hospitalization during the neonatal period were not independent predictors of lung function. Children sharing rooms with adult smokers had significantly lower levels of FEF25-75. Exposures to wood or kerosene stoves were, but to mosquito repellents were not, associated with decreased lung function.

    Wu CL, Hsu WH, Chiang CD, Kao CH, Hung DZ, King SL, et al.
    J. Toxicol. Clin. Toxicol., 1997;35(3):241-8.
    PMID: 9140317 DOI: 10.3109/15563659709001207
    BACKGROUND: Taking Sauropus androgynus, a Malaysian food, to reduce weight began as a fad in Taiwan in 1994. Some advocates of this fad developed pulmonary dysfunction. The aim of this study is to report the lung injury in patients taking Sauropus androgynus.

    METHODS: From July 1995 to November 1995, we investigated 104 nonsmoking patients (one male and 103 females) with chest roentgenography, pulmonary function, test, and Technetium 99m-labeled diethylene triamine penta-acetate (Tc-99m DTPA) radioaerosol inhalation lung scintigraphy.

    RESULTS: Among the 90 patients receiving Tc-99m DTPA inhalation lung scan, 46 (51.1%) patients had increased clearance of Tc-99m DTPA from lung and 20 (22.2%) patients had inhomogeneous deposition of the submicronic radioaerosol. Eighteen (18/100) patients had obstructive ventilatory impairment in pulmonary function test. Analyzing the results, we found that the patients with respiratory symptoms (n = 42) took more vegetables (p = 0.016), had increased clearance of Tc-99m DTPA (p = 0.010) and had lower FEV1 (p = 0.001), FEV1/FVC (p < 0.001), FEF25-75 (p = 0.001), VC (p = 0.002) and DLCO (p = 0.009) than the patients without respiratory symptoms (n = 62). FEV1 and FEV1/FVC were significantly reduced in patients with severe impairment of alveolar permeability. The cumulative dosage and duration of exposure were significantly associated with the reduction of FEV1 and FEV1/FVC.

    CONCLUSION: The lung injury after taking Sauropus androgynus involves alveoli and/or small airways and is manifest as obstructive ventilatory impairment with inhomogeneous aerosol distribution and increased lung epithelial permeability.

    Epithelial growth factor receptor (EGFR) is a cell surface transmembrane receptor that mediates the tyrosine signaling pathway to carry the extracellular messages inside the cell and thereby alter the function of nucleus. This leads to the generation of various protein products to up or downregulate the cellular function. It is encoded by cell erythroblastosis virus oncogene B1, so called C-erb B1/ERBB2/HER-2 gene that acts as a proto-oncogene. It belongs to the HER-2 receptor-family in breast cancer and responds best with anti-Herceptin therapy (anti-tyrosine kinase monoclonal antibody). HER-2 positive breast cancer patient exhibits worse prognosis without Herceptin therapy. Similar incidence and prognosis are reported in other epithelial neoplasms like EGFR + lung non-small cell carcinoma and glioblastoma (grade IV brain glial tumor). Present study highlights the role and connectivity of EGF with various cancers via signaling pathways, cell surface receptors mechanism, macromolecules, mitochondrial genes and neoplasm. Present study describes the EGFR associated gene expression profiling (in breast cancer and NSCLC), relation between mitrochondrial genes and carcinoma, and several in vitro and in vivo models to screen the synergistic effect of various combination treatments. According to this study, although clinical studies including targeted treatments, immunotherapies, radiotherapy, TKi-EGFR combined targeted therapy have been carried out to investigate the synergism of combination therapy; however still there is a gap to apply the scenarios of experimental and clinical studies for further developments. This review will give an idea about the transition from experimental to most advanced clinical studies with different combination drug strategies to treat cancer.

    Mice have served as an excellent model to understand the etiology of lung cancer for years. However, data regarding dual-stage carcinogenesis of lung squamous cell carcinoma (SCC) remain elusive. Therefore, we aim to develop pre-malignant (PM) and malignant (M) lung SCC in vivo using N-nitroso-tris-chloroethylurea (NTCU). BALB/C mice were allotted into two main groups; PM and M groups which received treatment for 15 and 30 weeks, respectively. Then, the mice in each main group were allotted into three groups; control, vehicle, and cancer (n = 6), which received normal saline, 70% acetone, and 0.04 M NTCU by skin painting, respectively. Histopathologically, we discovered a mix of hyperplasia, metaplasia, and dysplasia lesions in the PM group and intracellular bridge; an SCC feature in the M group. The M group was positive for cytokeratin 5/6 protein which confirmed the lung SCC subtype. We also found significantly higher (P lung SCC in mice model at appropriate weeks and the vehicle group was suggested to be adequate as control group for future research.

    Cell-based therapy has great potential to treat patients with lung diseases. The administration of cells into an injured lung is one method of repairing and replacing lost lung tissue. However, different types of delivery have been studied and compared, and none of the techniques resulted in engraftment of a high number of cells into the targeted organ. In this in vitro study, a novel method of cell delivery was introduced to investigate the possibility of delivering aerosolized skin-derived fibroblasts.

    Biomed Res Int, 2015;2015:248178.
    PMID: 25984527 DOI: 10.1155/2015/248178
    Indoor air quality (IAQ) has been the object of several studies due to its adverse health effects on children. Methods. A cross-sectional comparative study was carried out among Malay children in Balakong (2 studied preschools) and Bangi (2 comparative preschools), Selangor, with the aims of determining IAQ and its association with respiratory health. 61 and 50 children aged 5-6 years were selected as studied and comparative groups. A questionnaire was used to obtain an exposure history and respiratory symptoms. Lung function test was carried out. IAQ parameters obtained include indoor concentration of particulate matter (PM), volatile organic compounds (VOCs), carbon monoxide (CO), carbon dioxide (CO2), temperature, air velocity (AV), and relative humidity. Results. There was a significant difference between IAQ in studied and comparative preschools for all parameters measured (P < 0.001) except for CO2 and AV. Studied preschools had higher PM and CO concentration. FVC, FEV1, FVC% and FEV1% predicted values were significantly lower among studied group. Exposures to PM, VOCs, and CO were associated with wheezing. Conclusion. The finding concluded that exposures to poor IAQ might increase the risk of getting lung function abnormality and respiratory problems among study respondents.

    Ann Glob Health, 2020 07 28;86(1):84.
    PMID: 32775216 DOI: 10.5334/aogh.2895
    Background: Apart from being exposed to various hazards, there are several other factors that contribute to the deterioration of traffic police health.

    Objectives: A cross-sectional study was carried out to explore the association of occupational, socio-demographic, and lifestyle factors with lung functions in traffic policemen in Kuala Lumpur (KL) and Johor Bahru (JB).

    Methods: A spirometer was used to measure lung function of subjects, whereas a self-administered questionnaire was used to obtain their information on background data, lifestyle, and occupational factors. The statistical test used was Spearman rho's test and chi-square test; then, the factors were further tested using Logistic regressions.

    Findings: 134 male subjects were selected as respondents in this study with 83% response rate. Among all the factors tested, age (FVC: χ = 8.42(3), p = 0.04), (FEV: χ = 8.26(3), p = 0.04), rank (FVC: χ = 8.52(3), p = 0.04), (FEV: χ = 8.05(3), p = 0.04), duration of services (FVC: χ = 11.0(1), p = 0.04), (FEV: χ = 6.53(1), p = 0.01), and average working hours (with the Measured FVC (litre), r = -3.97, p < 0.001; Measured FEV1 (litre), r = -3.70, p < 0.001; Predicted FVC, r = -0.49, p < 0.001; Predicted FEV1, r = -0.47, p < 0.001; and %Ratio FEV1/FV, r = -0.47, p < 0.001) were significantly related to lung function among traffic police.

    Conclusions: Occupational factors play a crucial role, and hence, the authorities should take action in generating flexible working hours and the duration of services accordingly. The data from this study can help by serving as a reference to the top management of traffic police officers to develop occupational safety and health guideline for police officers to comply with the Occupational Safety and Health Act (OSHA, Act 514 1994).

    Aerosol-based cell therapy has emerged as a novel and promising therapeutic strategy for treating lung diseases. The goal of this study was to determine the safety and efficacy of aerosol-based airway epithelial cell (AEC) delivery in the setting of acute lung injury induced by tracheal brushing in rabbit. Twenty-four hours following injury, exogenous rabbit AECs were labelled with bromodeoxyuridine and aerosolized using the MicroSprayer® Aerosolizer into the injured airway. Histopathological assessments of the injury in the trachea and lungs were quantitatively scored (1 and 5 days after cell delivery). The aerosol-based AEC delivery appeared to be a safe procedure, as cellular rejection and complications in the liver and spleen were not detected. Airway injury initiated by tracheal brushing resulted in disruption of the tracheal epithelium as well as morphological damage in the lungs that is consistent with acute lung injury. Lung injury scores were reduced following 5 days after AEC delivery (AEC-treated, 0.25  ±  0.06 vs. untreated, 0.53  ±  0.05, P  lungs, following acute insults. These findings suggest that aerosol-based AEC delivery can be a valuable tool for future therapy to treat acute lung injury. Copyright © 2017 John Wiley & Sons, Ltd.

    Pneumonic pasteurellosis is an economically important infectious disease in the small ruminant industry which causes sudden death and loss for farmers. Nonetheless, this disease is still a common sight in sheep and goats in Malaysia, probably due to the unpopular usage of pasteurellosis vaccine or inappropriate vaccination practices. The aim of this study was designed to classify the severity of pneumonia via the establishment of auscultation scoring method and to quantify the acute phase proteins and heat shock proteins responses from vaccinated and non-vaccinated goats. Goat farms, consist of vaccinated and non-vaccinated farms, were selected in this study: where 15 clinically normal healthy goats and 9 pneumonic goats were selected from vaccinated farms whereas 15 clinically normal healthy goats and 31 pneumonic goats from non-vaccinated farms were selected for this study. Crackle lung sounds were not detected in both vaccinated and non-vaccinated normal goats. However, vaccinated pneumonic goats showed mild crackle lung sound while non-vaccinated pneumonic goats exhibited moderate crackle lung sound. There were significant increases (p

    Positron emission tomography (PET) combined with computed tomography (CT) is an established diagnostic modality that has become an essential imaging tool in oncological practice. However, thanks to its noninvasive nature and its capability to provide physiological information, the main applications of this technique have significantly expanded.(18)F-labelled fluorodeoxyglucose (FDG) is the most commonly used radiopharmaceutical for PET scanning and demonstrates metabolic activity in various tissues. Since activated inflammatory cells, like malignant cells, predominantly metabolise glucose as a source of energy and increase expression of glucose transporters when activated, FDG-PET/CT can be successfully used to detect and monitor a variety of lung diseases, such as infections and several inflammatory conditions.The added value of FDG-PET/CT as a molecular imaging technique relies on its capability to identify disease in very early stages, long before the appearance of structural changes detectable by conventional imaging. Furthermore, by detecting the active phase of infectious or inflammatory processes, disease progression and treatment efficacy can be monitored.This review will focus on the clinical use of FDG-PET/CT in nonmalignant pulmonary diseases.
