Disability and breathlessness in asthmatic patients--a scoring method by repetitive inspiratory effort

Loh LC, Puah SH, Ho CV, Chow CY, Chua CY, Jayaram J, et al.

PMID: 16393724

Measurement of disability and breathlessness in asthma is important to guide treatment. Using an incentive spirometer, Triflo II (Tyco Healthcare, Mansfield, MA, USA), we developed a three-minute respiratory exercise test (3-MRET) to score the maximal breathing capacity (MBC) and perception of dyspnea (POD) index by means of repetitive inspiratory efforts achieved within 3 minutes. POD index was calculated based on the ratio of breathlessness on visual analogue scale over MBC score. In 175 normal healthy subjects and 158 asthmatic patients of mild (n = 26), moderate (n = 78), and severe (n = 54), severity, the mean (95% CI) MBC scores in mild, moderate, and severe asthma patients were 168 (145-192), 153 (136-169), and 125 (109-142) respectively, and 202 (191-214) in normal subjects (p < 0.001). The mean POD index in mild, moderate, and severe asthma patients was 16 (9-23), 25 (14-37), and 57 (14-100), respectively, and 6 (4-7) in normal subjects (p < 0.001). Intraclass correlation coefficients for MBC score and POD index in 17 asthmatic and 20 normal subjects were high. In 14 asthmatic patients randomized to receiving nebulized beta2-agonist or saline in a cross-over, double-blind study, % forced expiratory volume in one second (FEV1) change correlated with % change in MBC score [r(s) = 0.49, p < 0.01] and POD index [r(s)-0.46, p = 0.012]. In 21 asthmatic and 26 normal subjects, the MBC score and POD index correlated with the walking distance and walking POD index of the six-minute walking test (6MWT). We conclude that 3MRET is discriminative between asthmatic patients of varying severity and normal subjects, is reproducible, is responsive to bronchodilator effect, and is comparable with 6MWT. Taken together, it has the potential to score disability and POD in asthma simply and effectively.

Fulltext Perception towards asthma clinical practice guidelines and appropriateness of prescribing practices--a comparison between government and private doctors

Loh LC, Wong PS

Med J Malaysia, 2007 Aug;62(3):210-3.
PMID: 18246909

A self-answered, anonymously completed, nationwide questionnaire survey was conducted between June 2002 and May 2003 among Malaysian doctors through post and at medical meetings. Findings based on 116 government and 110 private doctors who satisfactorily completed the forms (effective respondent rate: 30.1%) showed that more than 70% of government and private doctors claimed familiarity with asthma CPGs but proportionately more private doctors considered them "unworkable" and were reluctant to adopt them in their practice setting, quoting cost as the primary reason. Between those who frequently adopted the CPGs and those who did not, there was an equally high proportion of inappropriate prescribing. Despite the shortcomings of such a survey, our findings suggest that medicinal cost and practitioner's prescribing practices are important in the acceptance and execution of asthma CPGs recommendations.

PMID: 15997869

A self-answered, anonymously completed questionnaire survey was performed between June 2002 and May 2003 where doctors from government and private sectors in Malaysia were invited to participate by post or during medical meetings. One hundred and sixteen government doctors and 110 private doctors provided satisfactorily completed questionnaires (effective respondent rate: 30.1%). The most preferred medications for 'first-line', 'second-line' and 'third-line' treatment were for government doctors: inhaled short-acting beta2-agonist (SABA) (98%), inhaled corticosteroids (CS) (75%), and leukotriene antagonist (52%); and for private doctors: oral SABA (81%), inhaled CS (68%), and oral CS (58%). The first choice inhaler device for most government and private doctors were metered dose inhalers, with cost and personal preferences (for private doctors), and technical ability (for government doctors) as the key considerations when deciding on the choice of device. This benchmark data on the asthma prescribing practices of a healthcare delivery system fully dichotomized into government and private sector, provides evidence for practice differences affected by the nature of the healthcare system, and might have implications on healthcare systems of other countries that share similarities with that of Malaysia.
Adult community-acquired pneumonia in Malaysia: prediction of mortality from severity assessment on admission

Loh LC, Khoo SK, Quah SY, Visvalingam V, Radhakrishnan A, Vijayasingham P, et al.

Respirology, 2004 Aug;9(3):379-86.
PMID: 15363012

Prediction of mortality in patients with community-acquired pneumonia (CAP) can be assessed using clinical severity scores on admission to hospital. The clinical benefit of such tools is untested in Asian countries. The aim of this study was to determine the early adverse prognostic factors in patients hospitalized with CAP in Malaysia and to assess the usefulness of the British Thoracic Society (BTS) severity criteria.

PMID: 22605946 MyJurnal

Perceived breathlessness played an important role in guiding treatment in asthma. We developed a simple, user-friendly method of scoring perception of dyspnoea (POD) using an incentive spirometer, Triflo II (Tyco Healthcare, Mansfield, USA) by means of repetitive inspiratory efforts achieved within three minutes in 175 normal healthy subjects and 158 asthmatic patients of mild (n=26), moderate (n=78) and severe (n=54). Severity was stratified according to GINA guideline. The mean POD index in normal subjects, and asthmatic patients of mild, moderate and severe severity were: 6 (4-7) 16 (9-23), 25 (14-37), and 57 (14-100) respectively (p<0.001 One-Way ANOVA). Based on 17 asthmatic and 20 normal healthy subjects, intraclass correlation coefficients for POD index within subjects were high. In 14 asthmatic patients randomized to receiving nebulised b(2)-agonist or saline in a crossover, double-blind study, % FEV(1) change correlated with % changes in POD index [r(s) -0.46, p=0.012]. Finally, when compared with 6-minutes walking test (6MWT) in an open label study, respiratory POD index correlated with walking POD index in 21 asthmatic patients [r(s)= 0.58 (0.17 to 0.81) (p=0.007] and 26 normal subjects [0.50 (0.13 to 0.75) (p=0.008)]. We concluded that this test is discriminative between asthmatic patients of varying severity and from normal subjects, is reproducible, responsive to bronchodilator effect, and comparable with 6MWT. Taken together, it has the potential to score disability and POD in asthma effectively and simply.

PMID: 22589589 MyJurnal

While evidence indicates that early stage disease has better prognosis, the effect of delay in presentation and treatment of patients with non-small cell lung cancer (NSCLC) on survival is debatable. A retrospective study of 122 Malaysian patients with NSCLC was performed to examine the presentation and treatment delay, and its relation with patient survival. Median (25-75% IQR) interval between onset of symptoms and first hospital consultation (patient delay) and between first hospital consultation and treatment or decision to treat (doctor delay) were 2 (1.0- 5.0) and 1.1 (0.6-2.4) months respectively. The median survival rates in patient delay of <1, 1 to 3, and >3 months were 4.1 (9.9-1.7), 5.1 (10.9-3.2) and 5.7 (12.3-2.1) months respectively (log rank p=0.648), while in doctor delay, <30, 30-60, >60 days, the rates were 4.1 (10.8-1.8), 7.6 (13.7-3.2) and 5.3 (16.0-3.0) months respectively (p=0.557). Most patients presented and were treated in a relatively short time, and delays did not appear to influence survival. This Asian data is consistent with those from Western population, reiterating the need for public health measures that can identify disease early..
Survival in Patients with Non-Small Cell Lung Cancer Who Opted out of Cancer-Specific Therapy

Loh LC, Tan RY, Chan LY, Govindaraju S, Ratnavelu K, Kumar S, et al.

PMID: 22589601 MyJurnal

In Malaysia, many patients opted out of cancer-specific treatment for various reasons. This study was undertaken to investigate the survival rate of patients with stages I to III non-small cell lung cancer (NSCLC) who opted out of treatment, compared with those who accepted treatment. Case records of 119 patients diagnosed with NSCLC between 1996 and 2003 in two urban-based hospitals were retrospectively examined. Survival status was ascertained from follow-up medical clinic records or telephone contact with patients or their next-of-kin. Median (25-75% IQR) survival rate for 79 patients who accepted and 22 patients who opted out of treatment, were 8.6 (16.0-3.7) and 2.2 (3.5-0.8) months respectively [log rank p< 0.001, Kaplan-Meier survival analysis]. Except for proportionately more patients with large cell carcinoma who declined treatment, there was no significant difference between the two groups in relation with age, gender, ethnicity, tumour stage, and time delays between symptom onset and treatment or decision-to-treat. We concluded that there was a small but significant survival benefit in accepting cancer-specific treatment. The findings imply that there is no effective alternative therapy to cancer-specific treatment in improving survival. However, overall prognosis for patients with NSCLC remains dismal.
Perception of breathlessness by a 3-minute respiratory exerciser test predicts asthma exacerbations: a prospective cohort study

Loh LC, Teh PN

J Asthma, 2009 Aug;46(6):529-34.
PMID: 19657890 DOI: 10.1080/02770900801890489

We prospectively evaluated the use of a simple 3-Minute Respiratory Exerciser Test (3MRET) that estimates perception of dyspnea to identify patients at risk of asthma exacerbations. A total of 146 stable asthmatics (42 under-perceivers, 69 normal perceivers, and 35 over-perceivers) received follow-up for 12 months. The mean (SD) unscheduled visits to doctors among under-, normal, and over-perceivers were 1.8 (1.2), 2.2 (1.8), and 3.1 (2.3), respectively (p = 0.008). The mean (SD) hospital admissions among the groups were 1.3 (0.5), 1.2 (0.6), and 1.7 (1.3), respectively (p = 0.026). Compared to normal perceivers, over-perceivers had increased risks of unscheduled visits (OD: 5.12; 95% CI = 1.59 to 16.47) and hospital admissions (OD: 0.31; 95% CI = 0.23 to 0.41), defined as > or =2 events in 12 months. The association between over-perceiver and unscheduled visits remained significant after adjusting for forced expiratory volume in 1 second (FEV(1)). Sensitivity and specificity of over-perceivers are 77% and 47%, respectively, for unscheduled visits and 37% and 78%, respectively, for hospital admissions, with significantly better area under ROC for unscheduled visits (0.67 [95% CI = 0.56 to 0.77]; p = 0.003) than for hospital admissions (0.58 [0.471 to 0.70]; p = 0.127). We conclude that the 3MRET may have a role in identifying asthmatic patients with over-perception of dyspnea at risk of clinically important asthma exacerbations.
Fulltext Impact of various continuing medical education activities on clinical practice - a survey of Malaysian doctors on its perceived importance

Loh LC, Ong HT, Quah SH

Ann Acad Med Singap, 2007 Apr;36(4):281-4.
PMID: 17483859

INTRODUCTION: Medical talks, newsletter circulars, scientific meetings and conferences, and interaction with members of the pharmaceutical industry, have become convenient means of carrying out continuing medical education (CME) for many busy doctors.

MATERIALS AND METHODS: To study the perceived importance of these various CME activities, a self-completed posted questionnaire survey was conducted among registered practitioners of a densely populated urban state in Malaysia.

RESULTS: Of the 172 respondents [male, 77%; hospital-based, 37%; general practitioner (GP), 55%; private practice, 70%; respondent rate of 19.5%], most preferred local conferences and endorsements by local experts to their foreign counterparts. Meetings or conferences sponsored by the pharmaceutical industry were ranked similarly with those without such links, while the reputation of the pharmaceutical firms was of foremost importance. Among GPs (n = 95) and non-GPs (n = 77), medical society newsletters were rated significantly higher by GPs while overseas conferences were rated higher by non-GPs.

CONCLUSION: Our findings provide an important first look at this under-explored area among Malaysian doctors and described a high degree of acceptance for the involvement of the pharmaceutical industry in CME activities.
The development and comprehensibility of a pictorial asthma action plan

Roberts NJ, Mohamed Z, Wong PS, Johnson M, Loh LC, Partridge MR

Patient Educ Couns, 2009 Jan;74(1):12-8.
PMID: 18789626 DOI: 10.1016/j.pec.2008.07.049

OBJECTIVE: Written action plans are regarded as an important part of asthma self-management education and yet they may not be understood by those with limited literacy skills. This study was designed to produce an understandable pictorial asthma action plan.
METHODS: With advice from a group of doctors and nurses a "standard" written action plan was translated by a medical artist into a series of pictorial images. These were assessed using the techniques of guessability and translucency by a series of adults attending a specialist asthma clinic in London and the same process was subsequently used to assess comprehensibility of the images and plans amongst a group of Somalis living in Manchester, UK and Malaysians in Seremban, Malaysia.
RESULTS: Guessability testing showed that the majority of pictograms were well understood by each of the study groups. Translucency testing revealed close agreement with intended meaning for the majority of the images. One image, depicting extra use of reliever medication scored less well in all populations; two other images scored less well in the Somali and Malaysian groups and reflect less use of certain inhaler devices in other countries. The overall plan was well understood by all patients who were able to adequately recount the appropriate actions to take in different clinical scenarios.
CONCLUSION: We have developed a pictorial asthma action plan understandable by 3 different populations of patients with asthma.
PRACTICE IMPLICATIONS: Pictorial representations have been shown by other studies in other situations to be an effective method of reinforcing the spoken word. The pictorial asthma action plan developed for this study has been shown to be comprehensible, personalised to the individual in the usual fashion. It is now suitable for further evaluation in clinical practice.

Radiomics approach for survival prediction in chronic obstructive pulmonary disease

Cho YH, Seo JB, Lee SM, Kim N, Yun J, Hwang JE, et al.

Eur Radiol, 2021 Oct;31(10):7316-7324.
PMID: 33847809 DOI: 10.1007/s00330-021-07747-7

OBJECTIVES: To apply radiomics analysis for overall survival prediction in chronic obstructive pulmonary disease (COPD), and evaluate the performance of the radiomics signature (RS).
METHODS: This study included 344 patients from the Korean Obstructive Lung Disease (KOLD) cohort. External validation was performed on a cohort of 112 patients. In total, 525 chest CT-based radiomics features were semi-automatically extracted. The five most useful features for survival prediction were selected by least absolute shrinkage and selection operation (LASSO) Cox regression analysis and used to generate a RS. The ability of the RS for classifying COPD patients into high or low mortality risk groups was evaluated with the Kaplan-Meier survival analysis and Cox proportional hazards regression analysis.
RESULTS: The five features remaining after the LASSO analysis were %LAA-950, AWT_Pi10_6th, AWT_Pi10_heterogeneity, %WA_heterogeneity, and VA18mm. The RS demonstrated a C-index of 0.774 in the discovery group and 0.805 in the validation group. Patients with a RS greater than 1.053 were classified into the high-risk group and demonstrated worse overall survival than those in the low-risk group in both the discovery (log-rank test, < 0.001; hazard ratio [HR], 5.265) and validation groups (log-rank test, < 0.001; HR, 5.223). For both groups, RS was significantly associated with overall survival after adjustments for patient age and body mass index.
CONCLUSIONS: A radiomics approach for survival prediction and risk stratification in COPD patients is feasible, and the constructed radiomics model demonstrated acceptable performance. The RS derived from chest CT data of COPD patients was able to effectively identify those at increased risk of mortality.
KEY POINTS: • A total of 525 chest CT-based radiomics features were extracted and the five radiomics features of %LAA-950, AWT_Pi10_6th, AWT_Pi10_heterogeneity, %WA_heterogeneity, and VA18mm were selected to generate a radiomics model. • A radiomics model for predicting survival of COPD patients demonstrated reliable performance with a C-index of 0.774 in the discovery group and 0.805 in the validation group. • Radiomics approach was able to effectively identify COPD patients with an increased risk of mortality, and patients assigned to the high-risk group demonstrated worse overall survival in both the discovery and validation groups.
Correcting Metered-Dose Inhaler Technique vs Switching to Turbohaler in Asthmatic Patients a Study on 'Real-Life' Effectiveness

Loh LC, Ngor Teh P

Malays J Med Sci, 2004 Jan;11(1):60-5.
PMID: 22977361

In practice, asthmatic patients whose metered-dose inhaler (MDI) technique is inefficient are either corrected or changed to dry powder breath-actuated or spacer device that is easier to handle. Based on 'real life clinic circumstances', we studied 15 symptomatic asthmatic patients whose MDI techniques were inefficient that either received correction in their technique (n=9) or were changed to turbohaler (n=6). For comparison, we also studied a similar group of symptomatic asthmatic patients (n=6) with appropriate MDI techniques that were treated by doubling of inhaled corticosteroid (ICS) dose. After 4 weeks, FEV(1) and symptom scores in the turbohaler group was significantly improved from baseline but not in the corrected MDI group. The group whose ICS dose was doubled also showed significant improvement in symptom scores but not in FEV(1). We question the benefit gained by correcting MDI technique in some asthmatic patients compared to that of switching over to more user-friendly devices such as turbohaler. In our study, the improvement observed with turbohaler appears to be more than a mere doubling of drug delivery to the lungs and may relate to the recognized greater consistency of drug delivery by turbohaler compared to MDI device.
Fulltext Satisfaction levels and asthma control amongst Malaysian asthmatic patients on budesonide/formoterol maintenance and reliever therapy: experience in a real-life setting

Patient Relat Outcome Meas, 2012;3:71-8.
PMID: 23185124 DOI: 10.2147/PROM.S19211

BACKGROUND: Budesonide/formoterol used for both maintenance and reliever therapy has been shown to benefit patients with persistent asthma. We evaluated patient satisfaction and asthma control among Malaysian patients prescribed budesonide/formoterol as single maintenance and reliever therapy in a real-life clinical practice.
METHODS: Adult patients diagnosed with partially controlled or uncontrolled asthma were recruited in a 6-month, prospective, open-label study involving ten hospital-based chest clinics in Malaysia. Patients were prescribed one or two inhalations of budesonide/formoterol Turbuhaler (160/4.5 μg per inhalation) twice daily as maintenance therapy and additional inhalation as reliever therapy. Maintenance doses were decided by physicians based on Global Initiative for Asthma-defined treatment objectives. The primary outcome measure was the change in mean Satisfaction with Asthma Treatment Questionnaire (SATQ) scores from baseline to an average of 3 months and 6 months. Secondary outcome was the change in mean Asthma Control Questionnaire 5-item version (ACQ-5) scores from baseline to an average of 3 months and 6 months and the proportion of patients achieving the minimum clinically important difference.
RESULTS: Of 201 eligible patients recruited, 195 completed the study. Overall, SATQ mean (standard deviation) score was significantly improved from 5.1 (0.76) at baseline to 5.5 (0.58) (P < 0.001). The increase was observed in all domains of SATQ and had occurred at 3 months for most patients. ACQ-5 mean (standard deviation) score was significantly reduced from 2.2 (1.13) at baseline to 1.2 (0.95) (P < 0.001). A total of 132 (67.7.1%) patients had achieved the minimal clinically important difference (≥0.5) of ACQ-5 scores at study end.
CONCLUSION: In a nationwide study, budesonide/formoterol maintenance and reliever therapy achieved greater patient satisfaction and better asthma control compared with previous conventional asthma regimes among Malaysian patients treated in a real-life practice setting. Such an approach may represent an important treatment alternative for our local patients with persistent asthma.

Background: Positron Emission Tomography and Computed Tomography (PET-CT) imaging is shown to influence a decision change in managing non-small cell lung carcinoma (NSCLC). The introduction of such a facility in Malaysia is relatively recent, and its impact from its utility is currently being assessed.
Aim: In a tertiary referral centre possessing the only PET-CT facility in northern Peninsular Malaysia, we evaluated the potential roles of PET-CT in referred patients with non-small cell lung carcinoma.
Methodology: Sixty eligible adult cases with NSCLC, between September 2005 and December 2007, were retrospectively reviewed. Relevant data was collected using standard questionnaire for indications, staging of disease, and outcomes in terms of recurrence and response to prescribed cancer-specific therapy.
Results: The indications for PET-CT were: staging of a newly diagnosed non-small cell lung carcinoma (25.0%); post-operative restaging (21.7%); exclusion of recurrence or metastasis (18.3%); establishing diagnosis of carcinoma (13.3%); assessment of response to treatment (11.7%), and for surveillance (10.0%). The use of PET-CT was shown to induce a change in the staging, compared with non-PET conventional means in 69.2% of patients with newly diagnosed lung carcinoma (upstaged in 55.5%; downstaged in 44.5%) and in 65.0% of patients who underwent cancer-specific treatments (upstaged in 38.5%; downstaged in 61.5%). PET-CT detected recurrence in 62.5% who underwent the imaging to exclude a recurrence or metastasis.
Conclusion: PET-CT has affected the staging of a large proportion of our local Malaysian patients. Like elsewhere, the availability of such a facility is likely to have important influence in overall management of NSCLC in Malaysia.

It has been decided that IeJSME should be a general rather than specialty medical journal in that it would cover work ranging from bench science to clinical and medical education research. While this is to ensure the ease of soliciting sufficient manuscripts for sustainability of the journal, the other important reason is to provide learning opportunities for novice researchers, including undergraduate medical students, to improve their work in such a way that are publishable at a certain research quality. This intention is being birthed primarily with our 16-year old medical university and Malaysia in mind, although, as the journal title suggests, we aim that the work published in IeJSME will have international relevance and importance.

Fulltext Community-acquired pneumonia in Malaysian patients: addition of macrolide and the use of BTS "curb" index to assess severity

Loh LC

Med J Malaysia, 2006 Mar;61(1):128-30.
PMID: 16708753

Sir, I read with interest the elegantly written CME article by Liam C K recently!. The choice of empiric antibiotic(s) in treating hospitalized adult patients with communityacquired pneumonia (CAP) is important as it can influence clinical outcomes 2. As correctly pointed out by the author, patients with CAP requiring hospitalization should, in addition to a ~-lactam stable antibiotic, be covered with a macrolide, to combat atypical pathogens such as Legionella pneumophila, Mycoplasma pneumoniae, and Chlamydia pneumoniae. Such is the recommendation from most foreign guidelines 3. 4. Here I wish to add our own observation based on a prospective study conducted between 2002 and 2004 of 141 adult patients with CAP hospitalized in Seremban Hospital in which we studied the clinical outcomes of patients treated empirically with and without a macrolide added to their ~-lactam stable antibiotic, recently published in Respirology 5.
Fulltext Understanding academic publications: duplicate publication and role of impact factor in promotion

Academic performance is still primarily judged on publications. Not surprisingly, pressure to publish for the purpose of academic standing or promotion can be huge. People have been put off from an academic career simply because of this necessity. This is unfortunate because publishing our research findings or knowledge is our core business and why we become academicians. The notion that teaching is the academician’s chief duty is only half correct. We should and can enjoy publishing if we accept this as an inseparable part of our job. (Copied from article).
Fulltext Changing paradigms in the treatment of asthma

Loh LC

Family Physician, 2005;13(3):0-0.
MyJurnal

Significant changes have occurred in relation to how chronic asthma is being treated. Emphasis has now shifted from viewing asthma as a condition of smooth muscle dysfunction to one of chronic inflammation. As such, anti-inflammatory therapy forming the cornerstone of treatment represents the first important milestone in the evolution of asthma treatment. For this purpose, inhaled corticosteroid (ICS) is by far the most effective anti-inflammatory therapy. Another important milestone is the recognition of the superiority of adding long-acting β2-agonist (LABA) to ICS over escalating ICS dose alone or other forms of add-on therapies in treating asthmatic patients not responding to regular ICS alone. The effectiveness of adding LABA to ICS in treating asthma logically led to combining the two drugs into one single inhaler (salmeterol/fluticasone and budesonide/formoterol) that has the attractiveness of being user-friendly and ensuring that ICS is not missed out. The unique property of formoterol that allows for repetitive flexible dosing paved way to the concept of using Symbicort for both regular maintenance dosing and as required rescue medication. This revolutionary approach has been recently shown to provide improved asthma outcome, achieved at an overall lower or at least comparable corticosteroid intake, and may represent another evolutionary step in the treatment strategy of chronic asthma.
