METHODS: A systematic literature search was performed on five electronic databases from database inception to 3 November 2021. A two-step technique was used in the data synthesis process: (i) the barriers of LTBI management were identified using the COM-B model, followed by (ii) mapping of intervention functions from BCW to address the identified barriers.
RESULTS: Forty-seven eligible articles were included in this review. The findings highlighted the need for a multifaceted approach in tackling the barriers in LTBI management across the public, provider and system levels. The barriers were summarized into suboptimal knowledge and misperception of LTBI, as well as stigma and psychosocial burden, which could be overcome with a combination of intervention functions, targeting education, environment restructuring, persuasion, modelling, training, incentivization and enablement.
CONCLUSIONS: The remedial strategies using BCW to facilitate policy reforms in LTBI management could serve as a value-added initiative in the global tuberculosis control and prevention program.
METHODS: This was a randomized, double-blind clinical trial. The study included 64 patients over the age of 18 who had supraspinatus tendinopathy and had not responded to at least three months of conventional treatment. Patients were assigned to either receive 2 mL of PRP (N.=32) or prolotherapy (N.=32). The Shoulder Pain and Disability Index (SPADI) and the Numerical Rating Scale (NRS) were the primary outcomes. Secondary outcomes included shoulder range of motion (ROM), supraspinatus tendon thickness, and adverse effects, which were measured at baseline, 3, 6, and 6 months after injection. At six months, patient satisfaction was assessed.
RESULTS: Repeated measures ANOVA showed there was a statistically significant effect of time on total SPADI scores (F [2.75, 151.11], = 2.85, P=0.040) and the NRS (F [2.69, 147.86], = 4.32, P=0.008) within each group. There were no other significant changes over time or between groups. Significantly more patients in the PRP group experienced increased pain lasting less than two weeks after injection (χ2=11.94, P=0.030).
CONCLUSIONS: PRP and prolotherapy resulted in improved shoulder function and pain for patients with chronic supraspinatus tendinopathy who did not response to conventional treatment.
OBJECTIVES: To pool evidence on the safety and efficacy of MSCs in treating COVID-19 by observing MSC-related adverse effects as well as evaluating its effects in reducing inflammatory response and improving pulmonary function.
DATA SOURCES AND METHODS: Following literature search across six databases and one trial register, full-text retrieval, and screening against eligibility criteria, only eight studies were included for data extraction. All eight studies evaluated the use of umbilical cord-derived mesenchymal stromal/stem cell (UC-MSC), infused intravenously. Of these eight studies, six studies were included in meta-analysis on the incidence of mortality, adverse events (AEs), and serious adverse events (SAEs), and the levels of C-reactive protein (CRP) and interleukin (IL)-6. Meta-analysis on pulmonary function was not performed due to insufficient data.
RESULTS: MSC-treated group showed significantly lower risk of mortality than the control group (p = 0.03). No statistical significance was observed on the incidence of AEs (p = 0.78) and SAEs (p = 0.44), and the levels of CRP (p = 0.06) and IL-6 (p = 0.09).
CONCLUSION: MSCs were safe for use, with lower risk of mortality and no association with AEs. Regarding efficacy, descriptive analysis showed indications of improvement on the inflammatory reaction, lung clearance, and oxygenation status despite the lack of statistical significance in meta-analysis of CRP and IL-6. Nevertheless, more studies are needed for affirmation.
REGISTRATION: This systematic review and meta-analysis was registered on the PROSPERO database (no. CRD42022307730).
METHODS: Data from 21,439 expatriates were extracted from COVIDiSTRESS global survey. The outcome variable was perceived stress. The explanatory variables were age, perceived loneliness, trust (interpersonal and institutional). Pairwise correlation, and structural equation modelling were used to determine relationship among outcome and explanatory variables.
RESULTS: The majority of the expatriates were female (73.85%), married (60.20%), had college degree (47.76%), and employed (48.72%). Over 63% of the total expatriates reported that the COVID-19 pandemic changed their lives. The average age of the respondents was 40.4 years (± 13.7), and the average score of perceived stress, loneliness, interpersonal and institutional trust were 25.5, 7.4, 14.2 and 40.4, respectively. We found a moderate correlation of perceived stress with age, perceived loneliness, interpersonal trust and institutional trust (p
METHODS: This was a post-hoc analysis of pooled data from two cross-sectional studies that were previously conducted in Malaysia from 2017 to 2019, the results of which had been published separately. The parameters measured included post-bronchodilator FEV1 (PB-FEV1), exacerbations, and scores of modified Medical Research Council (mMRC), COPD Assessment Test (CAT), and St George's Respiratory Questionnaire for COPD (SGRQ-c). Descriptive, association, and correlation statistics were used.
RESULTS: Three hundred seventy-four patients were included in the analysis. The PB-FEV1 predicted was
METHODS: A total of 50 g/kg/day of 1% HCD was fed to three to four months old male rabbits weighing 1.8 to 2.0 kg for four and eight weeks to induce early and established atherosclerosis respectively. The body weight and lipid profile were measured at baseline and post-HCD intervention. Following euthanasia, the aorta was excised and prepared for histology and immunohistochemical analysis to confirm the stages of atherosclerosis.
RESULTS: The mean body weight of the rabbits in early and established atherosclerosis groups increased significantly up to 17.5% (p = 0.026) and 19.75% (p = 0.019) respectively compared to baseline. The total cholesterol level dramatically elevated up to 13-fold (p = 0.005) and 38-fold (p = 0.013) compared to baseline, after four and eight weeks of 1% HCD feeding respectively. The low-density lipoprotein level significantly increased up to 42-fold (p = 0.006) and 128-fold (p = 0.011) compared to baseline, after four and eight weeks of 1% HCD feeding respectively. Rabbits fed with four and eight weeks 1% HCD significantly developed 5.79% (p = 0.008) and 21.52% (p = 0.008) aortic lesion areas compared to the control group. Histological evaluation in the aorta showed accumulation of foam cells in early atherosclerosis group and formation of fibrous plaque and lipid core in the established atherosclerosis group. Rabbits fed with eight weeks HCD showed higher tissue expressions of ICAM-1, VCAM-1, e-selectin, IL-6, IL-8, NF-κBp65, and MMP-12 compared to four weeks of HCD intervention.
CONCLUSIONS: A total of 50 g/kg/day of 1% HCD for four and eight weeks is sufficient to induce early and established atherosclerosis in NZWR respectively. The consistent results through this method could facilitate researchers in inducing early and established atherosclerosis in NZWR.
DATA COLLECTION: A systematic search was performed using the following databases: Medline, EMBASE, CINAHL, and Cochrane from January 1990 till December 2022. Comparative studies of TPE in severe sepsis were selected. Adult and pediatric data were analyzed separately.
DATA SYNTHESIS: Eight randomized control trials and 6 observational studies (n = 50,142 patients) were included. Centrifugal TPE was the most common modality (209/280, 74.6% adults and 952/1026, 92.7% children). Every TPE study utilized different volume exchanges. Most TPE sessions (1173/1306, 89.8%) employed fresh frozen plasma (FFP) as replacement fluid and heparin as anticoagulant. Adults with severe sepsis supported with TPE using FFP had lower mortality (risk ratio, RR: 0.64 [95% confidence interval, CI: 0.49, 0.84]) compared to those who did not. In contrast, TPE was associated with increased mortality in septic children without thrombocytopenia-associated multiorgan failure (RR: 2.23, 95% CI: 1.93, 2.57). There was no difference in outcomes in patients supported with centrifugal and membrane TPE. In both populations, patients supported on TPE as a continuous regime had poorer outcome.
CONCLUSION: Current evidence indicates that TPE is a potential adjunct therapy in adults with severe sepsis but not in children.
OBJECTIVES: This study aims to determine the effectiveness of a newly developed Family Support Health Education (FASTEN) intervention in improving the health-related quality of life (HRQoL) among PTB patients in Melaka, as compared to the current conventional disease management.
MATERIALS AND METHODS: A single-blinded, randomized controlled field trial study design was conducted in Melaka from September 2019 until August 2021, involving newly diagnosed PTB patients. The participants were randomized either into the intervention group (FASTEN intervention) or into the control group (conventional management). They were interviewed by using a validated questionnaire that includes the Short Form 36 Health Survey version 2 (SF-36v2), at three time points: at diagnosis, two months and six months after diagnosis. Data were analyzed using IBM SPSS Statistics for Windows version 24. The Generalized Estimating Equations (GEE) analysis was used to evaluate the effectiveness of the intervention, in terms of the HRQoL score difference between the groups, adjusted for baseline covariates.
RESULTS: The HRQoL among PTB patients was lower than the HRQoL of general Malaysian population. Among the total 88 respondents, the three lowest HRQoL domains scores at baseline were Social Functioning (SF), Role limitation due to Physical condition (RP) and Vitality (VT) with the median (IQR) scores of 27.26 (10.03), 30.21 (11.23) and 34.77 (8.92) respectively. The median (IQR) for Physical Component Score (PCS) was 43.58 (7.44) and for Mental Component Score (MCS) was 40.71 (8.77). There were significant difference in the HRQoL median scores between the intervention group compared to the control group, as the Physical Functioning (PF) (p = 0.018), RP (p
RESULTS: The primary and secondary pectinase activity screenings by Aspergillus niger LFP-1 were performed using pectin screening agar and shake flask system, respectively. The finding revealed that the locally isolated strain is able to secrete favourable pectinase production. Before improvement, the pectinase production was 0.88 ± 0.09 U/mL. However, the improved conditions such as 6 days of the cultivation period, agitation speed of 150 rpm, inoculum size of 1 × 106 spores/mL, 2.5% (w/v) citrus pectin, and 0.4% (w/v) ammonium nitrate could significantly increase pectinase production up to 7.41 ± 0.24 U/mL, representing an 88% increase. In this study, supplementing 2.5% (w/v) citrus pectin to the culture medium as a carbon source increased enzyme production by up to 3.07 ± 0.17 U/mL. Meanwhile, 0.4% (w/v) ammonium nitrate was used as a nitrogen source yielding the highest enzyme activity with a value of 6.86 ± 0.07 U/mL.
CONCLUSION: Thus, the locally isolated fungal strain, A. niger LFP-1 has outstanding pectinase-producing capability and can be utilized for the commercial production of pectinase. The improved cultural conditions significantly increase pectinase production and shorten the incubation period from 8 days (before improvement) to 6 days (after improvement).
