METHODS: Parental-proxy scores of the Pediatric Quality of Life Inventory 4.0 core scales were obtained for 179 children with CHD and 172 siblings. Intra-class coefficients were derived to determine the levels of proxy-child agreement in 66 children aged 8-18 years. Multiple regression analysis was used to determine factors that impacted Pediatric Quality of Life Inventory scores.
RESULTS: Proxy scores were lower in children with CHD than siblings for all scales except physical health. Maximum differences were noted in children aged 5-7 years, whereas there were no significant differences in the 2-4 and 13-18 years age groups. Good levels of proxy-child agreement were found in children aged 8-12 years for total, psychosocial health, social, and school functioning scales (correlation coefficients 0.7-0.8). In children aged 13-18 years, the level of agreement was poor to fair for emotional and social functioning. The need for future surgery and severity of symptoms were associated with lower scores.
CONCLUSION: Differences in proxy perception of quality of life appear to be age related. The level of proxy-child agreement was higher compared with other reported studies, with lower levels of agreement in teenagers. Facilitating access to surgery and optimising control of symptoms may improve quality of life in this group of children.
METHODS: A multi-center study of multi-ethnic Asian patients with IBS was conducted in two phases: (i) an initial cross-sectional gut microbiota composition study of IBS patients and healthy controls, followed by (ii) a single-arm 6-week dietary interventional study of the IBS patients alone, exploring clinical and gut microbiota changes.
RESULTS: A total of 34 adult IBS patients (IBS sub-types of IBS-D 44.1%, IBS-C 32.4%, and IBS-M 23.5%) and 15 healthy controls were recruited. A greater abundance of Parabacteroides species with lower levels of bacterial fermenters and short-chain fatty acids producers were found among IBS patients compared with healthy controls. Age and ethnicity were found to be associated with gut microbiota composition. Following a low FODMAP dietary intervention, symptom and quality of life improvement were observed in 24 (70.6%) IBS patients. Symptom improvement was associated with adherence to the low FODMAP diet (46.7% poor adherence vs 92.9% good adherence, P = 0.014), and gut microbiota patterns, particularly with a greater abundance of Bifidobacterium longum, Anaerotignum propionicum, and Blautia species post-intervention.
CONCLUSION: Gut microbiota variation in multi-ethnic IBS patients may be related to dietary intake and may be helpful to identify patients who are likely to respond to a low FODMAP diet.
METHODS: Two hundred and nine MRSA strains from year 2011 to 2012 were collected from a tertiary teaching hospital in Malaysia. The strains were characterized by antimicrobial susceptibility testing, staphylococcal cassette chromosome mec (SCCmec) typing, detection of Panton-Valentine leukocidin (PVL) gene, multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). Patient's demographic and clinical data were collected and correlated with molecular data by statistical analysis.
RESULTS: Male gender and patient >50 years of age (p
OBJECTIVES: The aim of this paper is to study the association between audiovestibular symptoms and the presence of vascular loops and to study the association between vestibular paroxysmia and vascular loops.
DESIGN: This is a retrospective analysis of clinical, audiological and MRI findings of patients with and without vascular loops and vestibular paroxysmia from 2000 to 2020.
RESULTS: A total of 470 MRI Internal Auditory Meatus scans were performed during the study period of which, 71 (15.1%) had vascular loops and 162 (34.5%) had normal MRI which were used as controls. From the 233 subjects recruited, there were 37 subjects with VP and 196 non VP subjects were used as controls. There was no association between the vascular loop and control groups in terms of co-morbidity and audiovestibular symptoms. The VP group had a significantly older mean age of 51.8 (SD ± 10.3) as compared to the non VP group with the mean age of 45.6 (SD ± 15.5). The VP group had higher number of patients presenting with hearing loss at 97.3% when compared with those without VP (80.1%) (P = .01). The odds of having a vascular loop giving rise to VP was not statistically significant at 0.82 (95% CI 0.3735-1.7989) P = .62.
CONCLUSION: The vascular loop is a normal variant which may or may not give rise to audiovestibular symptoms or vestibular paroxysmia. Clinical assessment is still most important tool in deriving a diagnosis of VP and MRI may be useful to rule out other central causes.
OBJECTIVES: This paper is a pilot study designed to compare the effects of Bal Ex as a home-based VRT on the quality of life (EQ-5D), dizziness handicap (DHI) and mental health (DASS-21) against hospital-based VRT.
DESIGN: This was an assessor-blinded, randomized controlled pilot study where PPPD patients were randomly selected to undergo Bal Ex, the home-based VRT (intervention group) or hospital-based (control group) VRT. The participants were reviewed at 4 weeks and 12 weeks after the start of therapy to assess the primary endpoints using the subjective improvement in symptoms as reported by patients, changes in DHI scores, DASS-21 scores and EQ5D VAS scores.
RESULTS: Thirty PPPD patients successfully completed the study with 15 in each study group. Within 4 weeks, there were significant improvements in the total DHI scores as well as anxiety levels. By the end of 12 weeks, there were significant improvements in the DHI, DASS-21 and EQ5D. The degree of improvement between Bal Ex and the control was comparable.
CONCLUSION: VRT is an effective modality in significantly improving quality of life, dizziness handicap, depression, and anxiety levels within 3 months in PPPD. Preliminary results show Bal Ex is as effective as hospital-based VRT and should be considered as a treatment option for PPPD.
DATABASES REVIEWED: Science Direct, Pubmed, Embase via Ovid databases, and Cochrane library.
METHODS: This review following the guidelines of PRISMA, systematically and independently examined papers published up to March 2021 which fulfilled the predetermined criteria. PROSPERO Registration (CRD42020222334).
RESULTS: A total of 15 studies were included (MRI = 4, SPECT = 1, resting state fMRI = 4, task-based fMRI = 5, task-based fMRI + MRI = 1). Significant changes in the gray matter volume, cortical folding, blood flow, and connectivity were seen at different brain regions involved in vestibular, visual, emotion, and motor processing.
CONCLUSION: There is a multisensory dimension to the impairment resulting in chronic compensatory changes in PPPD that is evident by the significant alterations in multiple networks involved in maintaining balance. These changes observed offer some explanation for the symptoms that a PPPD patient may experience.Systematic Review Registration: This study is registered with PROSPERO (CRD42020222334).
