OBJECTIVE: To develop a Malaysian version of St George's respiratory COPD specific questionnaire (SGRQ-CM), to evaluate the full spectrum of psychometric properties (reliability, validity and responsiveness), to test the factor structure and to assess minimum clinically important difference for the SGRQ-CM, to be used in population of Malaysia.
METHODOLOGY: SGRQ-C was translated to Bahasa Malaysia using a standard protocol. 240 COPD patients were included in the study. All patients were followed-up for six months. Construct validity, internal consistency, item convergent validity, test-retest ability, responsiveness, factor analysis and MCID of the Malaysian version of SGRQ-C to be used in population of Malaysia were evaluated.
RESULTS: The Cronbach alpha coefficient and intraclass correlation coefficients (ICC) for SGRQ-CM were reported as 0.87, and 0.88 respectively. Correlation of SGRQ-CM with CAT, EQ-5D-5 L, mMRC dyspnea scales and FEV1%predicted were reported as 0.86, - 0.82, 0.72 and - 0.42 respectively. Correlation coefficient between the subscales and other clinical and health status measures ranged from r = - 0.35 to r = - 0.87. The MCID was reported as 5.07 (- 2.54-12.67).
CONCLUSION: The Malaysian version of SGRQ-C has a good psychometric property comparable to those of the original version and has a strong evidence of validity, reliability and responsiveness towards disease severity in Malaysian COPD patients. It can be recommended as a reliable quality of life measure for future research.
CASE PRESENTATION: We reported a rare case of large papillary fibroelastoma in the right atrium of a young gentleman which was complicated with pulmonary embolism. Transthoracic echocardiography identified a large pedunculated mass measuring 3.4cmX3.4cmX2cm in right atrium with stalk attached to interatrial septum. The intracardiac mass was resected surgically, which revealed papillary fibroelastoma in histology examination.
CONCLUSION: Differential diagnosis of intracardiac masses requires clinical information, laboratory tests and imaging modalities including echocardiography. Incidentally discovered papillary fibroelastomas are treated on the basis of their sizes, site, mobility and potential embolic complications. Due to the embolic risk inherent to intraacardiac masses, surgical resection represents an effective curative protocol in treating both symptomatic and asymptomatic right sided and left sided papillary fibroelastomas, with excellent long term postoperative prognosis.
OBJECTIVE: To investigate the effectiveness of the traditional Chinese Mawangdui exercise for patients with COPD in a mild to moderate stable stage.
METHODS: A total of 54 COPD patients in stable stage (Mawangdui group, n = 27; control group, n = 27) were enroled for a period of 12-weeks. The Mawangdui group practised the Mawangdui exercise, while the control group maintained daily activities without additional exercise. The outcomes measurements were pulmonary function, exercise capacity, back-leg-chest muscle strength, sit-and-reach flexibility, dyspnoea symptoms, and quality of life. The outcomes were assessed at baseline, 24 h, 6 weeks, and 12 weeks post-intervention.
RESULTS: Improvements were observed for Borg CR-10 score, SpO2, BMI, body fat%, fat mass, flexibility mMRC, and SGRQ scores (p
METHODS AND ANALYSIS: A multicentre, open-label randomised trial. Patients with MPE will be randomised 1:1 to daily or symptom-guided drainage regimes after IPC insertion. Patient allocation to groups will be stratified for the cancer type (mesothelioma vs others), performance status (Eastern Cooperative Oncology Group status 0-1 vs ≥2), presence of trapped lung (vs not) and prior pleurodesis (vs not). The primary outcome is the mean daily dyspnoea score, measured by a 100 mm visual analogue scale (VAS) over the first 60 days. Secondary outcomes include benefits on physical activity levels, rate of spontaneous pleurodesis, complications, hospital admission days, healthcare costs and QoL measures. Enrolment of 86 participants will detect a mean difference of VAS score of 14 mm between the treatment arms (5% significance, 90% power) assuming a common between-group SD of 18.9 mm and a 10% lost to follow-up rate.
ETHICS AND DISSEMINATION: The Sir Charles Gairdner Group Human Research Ethics Committee has approved the study (number 2015-043). Results will be published in peer-reviewed journals and presented at scientific meetings.
TRIAL REGISTRATION NUMBER: ACTRN12615000963527; Pre-results.
Methods: A quasi-experimental trial study was conducted to compare the effectiveness of nasal rinsing between two groups. The intervention group was instructed to perform nasal rinsing during ablution, while the control group was not asked to do nasal rinsing. Both groups were provided progress diaries to record the symptoms of respiratory tract infection, including cough, rhinorrhoea, nasal blockage, fever, and sore throat, as well as thick phlegm, shortness of breath, epistaxis, and changes in sense of smell. The groups were also instructed to record any visits to clinics for their symptoms throughout their stay in Makkah for the Hajj ritual.
Results: The study showed that nasal rinsing significantly reduced the symptoms of cough, rhinorrhoea, and nasal blockage. The intervention group had an increased number of visits to healthcare facilities for treatment, when compared to those of the control group. There were no significant differences in the groups regarding the symptoms of fever and sore throat.
Conclusion: Nasal rinsing can be included as part of intervention methods that include vaccination and the use of a face mask. Nasal rinsing can be easily practiced by the pilgrims, since it is a Sunnah act in ablution, which is an integral element of Muslims' daily life.
METHODS: The study population consisted of 53 participants, 23 patients with BVFI after endolaryngeal laser posterior cordectomy and 30 healthy volunteers. All of them had body plethysmography (airway resistance, Raw), spirometry (ratio of forced expiratory flow at 50% to forced inspiratory flow at 50%, FEF50/FIF50 and peak inspiratory flow, PIF), 6 min-walking-test (6MWT) and Medical Research Council (MRC) dyspnea scale measurements. The tests were repeated and reliability was evaluated using intraclass correlation (ICC) and Spearman correlation.
RESULTS: The reliability of Raw was high with ICC of 0.92, comparable to the spirometry measurements: FEF50/FIF50(ICC = 0.72) and PIF (ICC = 0.97). The mean of Raw was significantly higher in patient group. A strong significant correlation between Raw and MRC dyspnea scale (r = 0.79; p<0.05) and a moderate negative correlation between Raw and 6MWT (r = 0.4; p<0.05) was demonstrated.
CONCLUSION: Body plethysmography (Raw) is a reliable tool in objective measurement of upper airway resistance that reflects the patient's perception of breathlessness. A larger number of participants are necessary to confirm this finding.
