    OBJECTIVE: To investigate the prevalence of DD and AI with POP symptoms in females attending a urogynecology clinic, and to identify factors associated with DD and AI in POP symptoms patients.

    METHODS: Computer-based medical records of women with POP symptoms attending a urogynecology clinic in a referral tertiary center between January 2016 and December 2020 were reviewed. Demographic data were collected. Selected defecatory dysfunction (DD) and anal incontinence (AI) were recorded. The associations between patient characteristics, site and severity of prolapse, and DD and AI symptoms in POP patients were investigated for identified associated factors.

    RESULTS: The mean age of the 754 participants was 65.77 ± 9.44 years. Seven hundred and fifteen (94.83%) were menopause. The prevalence of DD and AI in patients with POP symptoms was 44.03% (332/754) and 42.04% (317/754) according to the PFBQ and medical history records, respectively. Advanced posterior wall prolapse (OR 1.59, 95% CI 1.10-2.30) and wider GH (OR1.23, 95% CI 1.05-1.43) were identified as risk factors for DD by multivariate analysis. Additionally, single-compartment prolapse (OR 0.4, 95% CI 0.21-0.76) and a stronger pelvic floor muscle assessed with brink score (OR 0.94, 95% CI 0.88-0.98) are protective factors for AI.

    CONCLUSION: DD and AI are prevalent among women with POP symptoms who visit a urogynecology clinic. DD should be evaluated in women with POP symptoms especially in women with increased genital hiatus and point Ap beyond the hymen. To prevent AI, women with POP should be encouraged to perform pelvic floor muscle training in order to increase pelvic floor muscle strength.

    BACKGROUND: Glomus tumors (GTs) are rare, comprising only 2% of all soft tissue tumors. Pulmonary GTs are exceptionally rare, with fewer than 80 cases reported to date. Little is known about the therapeutic outcomes of rigid bronchoscopy for endobronchial GT.

    METHODS: This is a case series of four patients with endobronchial GT who underwent therapeutic rigid bronchoscopy between February 2021 and June 2024.

    RESULTS: The ages of the patients in our series ranged from 32 to 75 years, and all patients were male. Cough and blood-tinged sputum were present in all patients with endobronchial GT. The tumor sizes ranged from 1 to 3 cm. Complete endoscopic resection and laser cauterization via rigid bronchoscopy were achieved in two patients. One patient had incomplete resection of a 3-cm tumor in the segmental bronchus that showed radiological evidence of bronchial wall invasion. This patient subsequently underwent lobectomy seven months after bronchoscopic resection. The fourth patient was lost to follow-up. There was no mortality throughout the follow-up periods that ranged from 2.8 to 42.5 months. Factors favoring successful rigid bronchoscopy resection for endobronchial GT include a benign tumor in the central airways without bronchial wall invasion.

    CONCLUSION: Endoscopic resection and laser cauterization using rigid bronchoscopy may be a viable option for patients with endobronchial GT when surgery is not practical.

    CLINICAL TRIAL NUMBER: Not applicable.

    BACKGROUND AND OBJECTIVES: An important proportion of patients with spontaneous intracerebral hemorrhage (ICH) undergo neurosurgical intervention to reduce mass effect from large hematomas and control the complications of bleeding, including hematoma expansion and hydrocephalus. The Tranexamic acid (TXA) for hyperacute primary IntraCerebral Hemorrhage (TICH-2) trial demonstrated that tranexamic acid (TXA) reduces the risk of hematoma expansion. We hypothesized that TXA would reduce the frequency of surgery (primary outcome) and improve functional outcome at 90 days in surgically treated patients in the TICH-2 data set.

    METHODS: Participants enrolled in TICH-2 were randomized to placebo or TXA. Participants randomized to either TXA or placebo were analyzed for whether they received neurosurgery within 7 days and their characteristics, outcomes, hematoma volumes (HVs) were compared. Characteristics and outcomes of participants who received surgery were also compared with those who did not.

    RESULTS: Neurosurgery was performed in 5.2% of participants (121/2325), including craniotomy (57%), hematoma drainage (33%), and external ventricular drainage (21%). The number of patients receiving surgery who received TXA vs placebo were similar at 4.9% (57/1153) and 5.5% (64/1163), respectively (odds ratio [OR] 0.893; 95% CI 0.619-1.289; P -value = .545). TXA did not improve outcome compared with placebo in either surgically treated participants (OR 0.79; 95% CI 0.30-2.09; P = .64) or those undergoing hematoma evacuation by drainage or craniotomy (OR 1.19 95% 0.51-2.78; P -value = .69). Postoperative HV was not reduced by TXA (mean difference -8.97 95% CI -23.77, 5.82; P -value = .45).

    CONCLUSION: TXA was not associated with less neurosurgical intervention, reduced HV, or improved outcomes after surgery.

    Four hundred and one cases of ameloblastoma of the jaw diagnosed in the Division of Stomatology, Institute for Medical Research, Kuala Lumpur, between 1967 and 1991 have been analysed. There were 214 males and 187 females. Of these, 50.1% were Malays, 34.7% Chinese, 8.2% Indians and 7.0% other races. Seventy-two percent of patients were in the second, third and fourth decades of life (mean age: 30.8 years). Ninety-three percent of tumours occurred in the mandible and 6.5% in the maxilla. There were 337 cases of conventional ameloblastoma, 49 cases of the unicystic variant and four cases of peripheral ameloblastoma. The predominant histologic patterns were plexiform (34.2%), follicular (16.5%) and mixture of both (17.7%). Majority of the cases were conservatively treated by enucleation. Fifty-nine cases presented with recurrences. Present findings were generally compatible with regional serial studies reported from Thailand, Singapore and Japan.

    Prevalence and incidence of HIV among people aged 50 years and older continue to rise worldwide, generating increasing awareness among care providers, scientists, and the HIV community about the importance of brain health in older adults with HIV. Many age-related factors that adversely affect brain health can occur earlier and more often among people with HIV, including epigenetic ageing, chronic medical conditions (eg, cardiovascular disease), and age-related syndromes (eg, frailty). Extensive dialogue between HIV community leaders, health-care providers, and scientists has led to the development of a multidimensional response strategy to protect and enhance brain health in people ageing with HIV that spans across public health, clinical spaces, and research spaces. This response strategy was informed by integrated ageing care frameworks and is centred on prevention, early detection, and management of brain health issues associated with HIV (eg, neurocognitive disorders), with specific considerations for low-resource or middle-resource countries. A collaborative, international, and data-informed update of the diagnostic criteria for HIV-associated neurocognitive disorders is a cornerstone of the proposed response strategy. The proposed response strategy includes a dynamic, international, online knowledge hub that will provide a crucial community resource for emerging evidence on the brain health of people ageing with HIV.

    BACKGROUND: A decline in taste sensitivity from aging leads people with a higher salt threshold to frequently add more salt to their food, which attributed to decreased cognitive efficiency. This scoping review aimed to gather the latest evidence on the relationship between salt perception and cognitive impairment which is essential in the development of new intervention and prevention strategies.

    METHODS: Studies published between January 2014 and March 2024 were searched across four databases: PubMed, the Cochrane Library, Scopus, and EBSCO. Data extraction involved gathering details on the study design, participant demographics, methods for assessing cognitive function and salt perception, considering confounding factors, and synthesizing the primary outcomes.

    RESULTS: Six studies were included in the analysis, five cross-sectional studies and a longitudinal study. These studies revealed various associations between salt perception and cognitive impairment. Specifically, findings from a three-year longitudinal study suggested that lower salt sensitivity was associated with poorer cognitive scores, which is consistent with the results of two other studies. However, the remaining three studies did not find significant differences (p > 0.05) in salt taste perception related to cognitive status. Furthermore, a study identified executive function as another significant factor influencing salt taste perception.

    CONCLUSION: These findings highlight the link between cognitive decline in salt perception, which provide an indication of salt intake and related health risks. There is a need to explore the mechanisms of salt taste sensitivity and its impact on cognitive health should be encouraged.

    We hypothesized that persistent lifetime (PLT) images could represent tumor imaging traits, locations, and persistent contrasts of topological components (connected and hole components) corresponding to gene mutations such as epidermal growth factor receptor (EGFR) mutant signs. We aimed to develop a topological radiogenomic approach using PLT images to identify EGFR mutation-positive patients with non-small cell lung cancer (NSCLC). The PLT image was newly proposed to visualize the locations and persistent contrasts of the topological components for a sequence of binary images with consecutive thresholding of an original computed tomography (CT) image. This study employed 226 NSCLC patients (94 mutant and 132 wildtype patients) with pretreatment contrast-enhanced CT images obtained from four datasets from different countries for training and testing prediction models. Two-dimensional (2D) and three-dimensional (3D) PLT images were assumed to characterize specific imaging traits (e.g., air bronchogram sign, cavitation, and ground glass nodule) of EGFR-mutant tumors. Seven types of machine learning classification models were constructed to predict EGFR mutations with significant features selected from 2D-PLT, 3D-PLT, and conventional radiogenomic features. Among the means and standard deviations of the test areas under the receiver operating characteristic curves (AUCs) of all radiogenomic approaches in a four-fold cross-validation test, the 2D-PLT features showed the highest AUC with the lowest standard deviation of 0.927 ± 0.08. The best radiogenomic approaches with the highest AUC were the random forest model trained with the Betti number (BN) map features (AUC = 0.984) in the internal test and the adapting boosting model trained with the BN map features (AUC = 0.717) in the external test. PLT features can be used as radiogenomic imaging biomarkers for the identification of EGFR mutation status in patients with NSCLC.

    OBJECTIVE: The management of large central giant cell granuloma (CGCG) can pose a significant surgical challenge. In such circumstances, the use of denosumab has been proposed with the literature reporting varying degrees of success. Histopathological assessment of CGCG post-denosumab treatment remains unknown. The current case series aims to address this lack of information and supplement the literature and the debate with evidence.

    STUDY DESIGN: The current case series is a retrospective review of historic cases accumulated from 3 different hospitals. Patients treated with denosumab for large or unresectable GCGC who subsequently underwent either surgical debulk or resection post drug treatment with histological tissue for assessment were included.

    RESULTS: A total of 4 patients were included in this study. All cases showed radiographic response. However histological assessment identified giant cells in 3 of the 4 cases, 2 of which showed clinical recurrence. All cases demonstrated irregular woven bone formation toward the periphery of the lesion suggesting partial response.

    CONCLUSIONS: The current case series provides some insight regarding the response of CGCG to denosumab and preliminary histopathological information toward the ongoing debate regarding the medical management of CGCG. (Oral Surg Oral Med Oral Pathol Oral Radiol YEAR;VOL:page range).

    BACKGROUND: The role of ECG in ruling out myocardial complications on cardiac magnetic resonance (CMR) is unclear. We examined the clinical utility of ECG in screening for cardiac abnormalities on CMR among post-hospitalised COVID-19 patients.

    METHODS: Post-hospitalised patients (n = 212) and age, sex and comorbidity-matched controls (n = 38) underwent CMR and 12‑lead ECG in a prospective multicenter follow-up study. Participants were screened for routinely reported ECG abnormalities, including arrhythmia, conduction and R wave abnormalities and ST-T changes (excluding repolarisation intervals). Quantitative repolarisation analyses included corrected QT (QTc), corrected QT dispersion (QTc disp), corrected JT (JTc) and corrected T peak-end (cTPe) intervals.

    RESULTS: At a median of 5.6 months, patients had a higher burden of ECG abnormalities (72.2% vs controls 42.1%, p = 0.001) and lower LVEF but a comparable cumulative burden of CMR abnormalities than controls. Patients with CMR abnormalities had more ECG abnormalities and longer repolarisation intervals than those with normal CMR and controls (82% vs 69% vs 42%, p

    BACKGROUND: Chimeric Antigen Receptor (CAR) T-cell therapy has arisen as a revolutionary treatment for hematologic malignancies. Our study aimed to evaluate how sex differences affect outcomes and complications following CAR T-cell therapy.

    METHODS: Utilizing the Nationwide Readmissions Database (2018-2020), we identified patients and divided them into male and female groups. Hospital outcomes and complications were compared among these two groups after propensity score matching to match groups based on comorbidities, producing two comparable cohorts.

    RESULTS: We analyzed 2928 patients (1832 males, 62.6%, mean age 60.3 ± 13.7 years; 1096 females, 37.4%, mean age 59.1 ± 13.8 years). After propensity score matching (1:1ratio), 1092 males and females were compared. There were no significant sex differences in early mortality (adjusted odd ratios (aOR): 1.04 [95% CI 0.69-1.57]), 30-day readmissions (aOR: 1.05 [95% CI 0.86-1.30]), or nonhome discharge (aOR: 0.89 [95% CI 0.60-1.31]). Females had higher odds of leukopenia (aOR: 1.26 [95% CI 1.06-1.50]) but lower odds of acute kidney injury (aOR: 0.68 [95% CI 0.52-0.88]).

    CONCLUSIONS: No sex differences were found in hospital outcomes, including early mortality, 30-day readmission, and nonhome discharge after CAR T-cell therapy.

    OBJECTIVE: The aims of this study were to report prevalence of chronic pain and to examine whether chronic pain influence healthcare usage among elderly Malaysian population.
    METHODS: This was a sub-population analysis of the elderly sample in the Malaysia's Third National Health and Morbidity Survey (NHMS III) 2006, a nation-wide population based survey. A subset of 4954 elderly aged 60 years and above was used in the analysis. Chronic pain, pain's interference and outcome variables of healthcare utilization (hospital admission and ambulatory care service) were all measured and determined by self-report.
    RESULTS: Prevalence of chronic pain among elderly Malaysian was 15.2% (95% CI: 14.5, 16.8). Prevalence of chronic pain increased with advancing age, and the highest prevalence was seen among the old-old group category (21.5%). Across young-old and old-old groups, chronic pain was more prevalent among females, Indian ethnicity, widows/widowers, rural residency and those with no educational background. Our study showed that chronic pain alone increased hospitalization but not visits to ambulatory facilities. Presence of chronic pain was significantly associated with the frequency of hospitalization (aIRR 1.11; 95% CI 1.02, 1.38) but not ambulatory care service.
    CONCLUSIONS: Chronic pain is a prevalent health problem among the elderly in Malaysia and is associated with higher hospitalization rate among the elderly population. This study provides insight into the distribution of chronic pain among the elderly and its relationship with the patterns of healthcare utilization.

    The elderly population in Malaysia is growing rapidly. Some of the most vulnerable are in residential care. Research is needed into the characteristics of this population to aid clinicians and policy makers in addressing the needs of this group. This observational, cross-sectional study aims to determine prevalence of undetected cognitive impairment and depression in elderly care home residents in Malaysia. One hundred and sixty-seven people over 60 years of age living in a state run residential home were interviewed. Validated assessment tools were used to measure dependency, cognitive impairment and depression. The prevalence of probable dementia is 36.5%, with increasing prevalence with age and level of dependence. Prevalence of depression is 67.0% (major depression 13.2%), with more depression in males and in the Indian population. None of the identified cases had been previously investigated or treated for dementia or depression.

    Geriatric medicine practice requires a multidimensional and multidisciplinary assessment to provide a holistic overview of the older patients. During the current COVID-19 pandemic time, it becomes more critical to ensure that the elderly patients continue to receive regular geriatric care for their pre-existing chronic illness and at the same time avoid unnecessary exposure to COVID-19 virus. Geriatric telemedicine clinic provides a convenient solution to ensure continuity of care for the older patients. Careful patient selection, technical requirement, geriatric assessment via audio-visual communication, and caretaker involvement were among the important issues discussed in this article.

    INTRODUCTION: Hospitalisations can pose hazards and may not be an appropriate care setting for frail nursing home (NH) residents. Few studies have quantified the extent of NH resident hospitalisations in Singapore, hence we aimed to address this knowledge gap by studying characteristics of unplanned hospitalisations over a 1-year period.

    METHOD: This was a retrospective cohort study of 9922 subsidised residents across 59 NHs in Singapore, with analysis using administrative healthcare data. Key measures included inpatient admission and emergency department visit rates, final discharge diagnoses and estimated costs. We examined correlates of inpatient admissions with a multivariable zero-inflated negative binomial regression model incorporating demogra-phics, institutional characteristics and Charlson Comorbidity Index.

    RESULTS: There were 6620 inpatient admissions in 2015, equivalent to 2.23 admissions per 1000 resident days, and the majority were repeat admissions (4504 admissions or 68.0%). Male sex (incidence rate ratio [IRR] 1.23), approaching end-of-life (IRR 2.14), hospitalisations in the past year (IRR 2.73) and recent NH admission within the last 6 months (IRR 1.31-1.99) were significantly associated with inpatient admission rate. Top 5 discharge diagnoses were lower respiratory tract infections (27.3%), urinary tract infection (9.3%), sepsis (3.1%), cellulitis (1.9%) and gastroenteritis (1.1%). We estimated the total system cost of admissions of subsidised residents to be SGD40.2 million (USD29.1 million) in 2015.

    CONCLUSION: We anticipate that unplanned hospitali-sation rate will increase over time, especially with an increasing number of residents who will be cared for in NHs. Our findings provide a baseline to inform stakeholders and develop strategies to address this growing problem.

    This study was conducted to describe corneal endothelial cell density and morphology in Malay eyes. Non-contact specular microscopy was performed in 125 eyes of 125 Malay volunteers, aged 20-87 years. Studied parameters included endothelial cell density (CD), mean cell area (MCA), coefficient of variation (CV) in cell area, as well as hexagonal appearance of the cells. Mean endothelial cell density in the study population was 2648 +/- 310 cell/mm(2). Mean CA, CV and percentage of hexagonal cells were 382.8 +/- 47.7microm(2), 58.1 +/- 22.6, 44.3% +/- 11.5% respectively. There was a statistically significant decrease in endothelial cell density (correlation - 0.300, P = 0.001) and CV in cell size (correlation - 0.208, P = 0.02) with age. There was a statistically significant increase in mean cell area (correlation 0.300, P = 0.001) with increasing age. The correlation between age and percentage of hexagonal cells was insignificant (correlation 0.074, P = 0.41). In conclusion, a consistent decrease was noted in the endothelial cell density with increasing age. The differences in endothelial cell density between genders were statistically insignificant.

    Colorectal carcinogenesis is a complex multistep process that includes changes in histomorphological appearance of the colonic mucosa and changes at molecular level. Aberrant crypt foci (ACF) was first described by Bird in 1987 on examination of methylene-blue-stained colonic mucosa of azoxymethane-treated mice under light microscopy. Since then ACF was considered as the earliest preneoplastic change that can be seen in the colonic mucosa. The aim of this study was to look at the histomorphology and distribution of ACF in colorectal carcinoma. 50 formalin-fixed archival colectomy specimens for colorectal carcinoma were examined under light microscopy after staining with 0.2% methylene blue. ACF was identified by larger and darker crypts with thickened epithelium, and often elevated from adjacent normal mucosa. ACF was found in 41 of 50 colectomy specimens examined. There were 328 ACF consisting of 36 (11.0%) ACF without hyperplasia or dysplasia, 263 (80.2%) ACF with hyperplasia and 29 (8.8%) ACF with dysplasia. Of these 29 ACF with dysplasia, 25 showed low grade dysplasia and four high grade dysplasia. The density of ACF was higher in the left colon, those older than 65 years of age and among males but these findings were statistically not significant. The crypt multiplicity of hyperplastic ACF (30.149, SD 28.395) was larger than dysplastic ACF (20.613, SD 40.128). The spectrum of histological changes observed probably represent the evolution of ACF in colorectal carcinogenesis.
