METHODS: The brain MR images of eight patients with Nipah virus infection were reviewed. All patients tested negative for acute Japanese encephalitis virus. Seven patients had contrast-enhanced studies and six had diffusion-weighted examinations.
RESULTS: All patients had multiple small bilateral foci of T2 prolongation within the subcortical and deep white matter. The periventricular region and corpus callosum were also involved. In addition to white matter disease, five patients had cortical lesions, three had brain stem involvement, and a single thalamic lesion was detected in one patient. All lesions were less than 1 cm in maximum diameter. In five patients, diffusion-weighted images showed increased signal. Four patients had leptomeningeal enhancement and four had enhancement of parenchymal lesions.
CONCLUSION: The brain MR findings in patients infected with the newly discovered Nipah paramyxovirus are different from those of patients with Japanese encephalitis. In a zoonotic epidemic, this striking difference in the appearance and distribution of lesions is useful in differentiating these diseases. Diffusion-weighted imaging was advantageous in increasing lesion conspicuity.
MATERIALS AND METHODS: All patients diagnosed with osteoporotic hip fracture admitted to Sarawak General Hospital from June 2019 to March 2021 were recruited, and demographic data and clinical features were obtained.
RESULTS: There were 140 patients with osteoporotic hip fracture, and 40 were men (28.6%). The mean age for males was 74.1 ± 9.5 years, while the mean age for females was 77.4 ± 9.1 years (p=0.06). The types of fracture consisted of neck of femur=78, intertrochanteric=61 and subtrochanteric=1. More men were active smokers (15% vs 1%, p<0.001). There were 20 men with secondary osteoporosis (50%), while 13 women (13%) had secondary osteoporosis (p<0.001). The causes of secondary osteoporosis among the men were hypogonadism, COPD, glucocorticoid-induced osteoporosis, renal disease, androgen deprivation therapy, thyroid disorder, prostate cancer and previous gastrectomy. There were two deaths among the men and four deaths among the women during the inpatient and 3 months follow-up period. There was no statistical significance between the mortality rates between male patients (5%) and female patients (4%) (p=0.55).
CONCLUSION: There were more females with osteoporotic hip fractures, and there were significantly more males with secondary osteoporotic hip fractures.
OBJECTIVE: This systematic review and meta-analysis assess the effectiveness of salivary biomarkers in the diagnosis and prognosis of RA, examining current evidence and proposing avenues for future research.
METHODOLOGY: A literature review following PRISMA 2021 guidelines was conducted using PubMed, Scopus, Web of Science, and Google Scholar to identify studies from the past five years on salivary biomarkers in RA patients compared to healthy controls.
RESULT: The review focused on original research articles, and meta-analysis was performed on studies reporting standard deviation values for inflammatory markers such as IL-6, IL-8, MMP-8, and TNF-alpha. The meta-analysis included eleven studies with 394 RA patients and 255 healthy controls, evaluating IL-8, IL-6, MMP-8, and TNF-α as RA biomarkers. IL-8 showed a mean difference of 7.32 (CI: -5.48 to 20.13), not statistically significant, favouring controls. IL-6 had a CI of -0.09 (CI: -2.20 to 2.02) with high heterogeneity (I² = 98%), suggesting its potential as a diagnostic and prognostic biomarker. TNF-α and MMP-8 showed no significant differences (CIs: 4.54 and 2.71, respectively).
CONCLUSION: This systematic review and meta-analysis emphasize saliva's potential in identifying RA biomarkers, especially IL-6, which is associated with the disease's pathogenesis. However, significant evidence heterogeneity necessitates larger, multicentric studies for validation.
METHODS: The present aims to examine the impact of CFH rs1061170 (Y402H), C2 rs9332739 (E318D), and C3 rs2230199 (R102G) gene polymorphisms and AMD risk, in addition, Deleterious missense SNPs in CFH, C2, and C3 were analyzed for stability, conservation, and structural impact using multiple computational approaches. Relevant studies were searched in PubMed, Web of Science, and Google Scholar databases between the years Jan 2020 and 30 April 2026 and covered a total of nine case-control articles.
RESULTS: Meta-analysis demonstrated significant associations of CFH rs1061170 and C3 rs2230199 polymorphisms with AMD susceptibility under specific genetic models (p
