METHODS: Healthy women (aged 45-69 years) of Chinese, Malay and Indian ethnicities attending well-women clinics at the National University Hospital, Singapore, completed the Pittsburgh Sleep Quality Index (PSQI). A PQSI score >5 denoted poor sleep quality. The women filled out validated questionnaires covering menopausal and genito-urinary symptoms, and mental health...

The rising cost of oncological drugs poses a global challenge to patients, insurers, and policy makers, with the leading drugs worldwide by revenue from immune checkpoint inhibitors (ICIs). Despite its cost, ICI is marked as a paradigm shift, offering the potential of a long-term cure. To reduce cost, an attenuated dose of ICI based on pharmacological principles can be used while maintaining efficacy. This real-world study aims to examine the prescribing patterns, the effect of financial constraints, and the outcomes in non-small cell lung cancer (NSCLC)...

BACKGROUND: Growth differentiation factor-9 (GDF9) and bone morphogenetic protein-15 (BMP15) are critical paracrine regulators of female fertility and are predominantly expressed by oocytes. However, it is unknown if serum concentrations reflect changes in ovarian function and/or reproductive endocrine disorders. This study aimed to determine if serum GDF9/BMP15 are associated with ovarian, pituitary, estrogenic, androgenic and metabolic characteristics and the ovarian pathologies, polycystic ovarian morphology (PCOM) and polycystic ovary syndrome (PCOS)...

Burrhole craniostomy is commonly performed for subdural hematoma (SDH) evacuation, but residual scalp depressions are often cosmetically suboptimal for patients. OsteoplugTM , a bioresorbable polycaprolactone burrhole cover, was introduced by the National University Hospital, Singapore, in 2006 to cover these defects, allowing osseous integration and vascular ingrowth. However, the cosmetic and safety outcomes of OsteoplugTM -C-the latest (2017) iteration, with a chamfered hole for subdural drains-remain unexplored...

OBJECTIVES: Bladder cancer is a common type of malignancy. UBC®Rapid is a novel immunoassay detecting urine cytokeratin 8/18 protein. Studies have shown good accuracy of UBC®Rapid in detecting bladder cancer. UBC®Rapid has however to date not been evaluated in Asian patients. We evaluated UBC®Rapid in detecting Asian bladder cancer, together with urine cytology. METHODS: In total, 112 patients were recruited from National University Hospital Singapore and 103 patients were included in this study, comprising 49 patients with bladder urothelial carcinoma (UC), 21 patients with bladder benign lesions, and 33 patients with normal bladder...

Importance: The Cancer and Aging Research Group (CARG) prediction model for chemotherapy-related toxic effects has been developed but not yet validated in older Asian adults. In view of differences in drug metabolism and toxic effect reporting in the Asian population, the ability of this tool to guide the cancer treatment decision-making process in older Asian adults needs to be assessed. Objective: To examine the validity of the CARG predictive model in a multiethnic Asian cohort of older adults...

Previous studies have explored the associations of retinal vessel calibre, measured from retinal photographs or fundus images using semi-automated computer programs, with cognitive impairment and dementia, supporting the concept that retinal blood vessels reflect microvascular changes in the brain. Recently, artificial intelligence deep-learning algorithms have been developed for the fully automated assessment of retinal vessel calibres. Therefore, we aimed to determine whether deep-learning-based retinal vessel calibre measurements are predictive of risk of cognitive decline and dementia...

Background: Quantitative electroencephalography (QEEG) is a reliable and non-invasive diagnostic tool to quantify cortical synaptic injury or loss in the clinical assessment of neurodegenerative diseases, and may be able to differentiate various types of dementia. We investigated if QEEG indices can differentiate Parkinson's Disease (PD) with nondementia (PD-ND) from PD with dementia (PDD), and to determine if QEEG indices correlate with inflammation and lipid metabolism markers in PD...

Background: The COVID-19 pandemic has profoundly influenced the world. In wave after wave, many countries suffered from the pandemic, which caused social instability, hindered global growth, and harmed mental health. Although research has been published on various mental health issues during the pandemic, some profound effects on mental health are difficult to observe and study thoroughly in the short term. The impact of the pandemic on mental health is still at a nascent stage of research...

Introduction: Musculoskeletal injuries are the most common reason for surgical intervention in polytrauma patients.

The secondary aims are to: internally and externally validate the prediction model; and compare its performance with two existing models. RESEARCH DESIGN AND SETTING: Data of inpatients aged ≥18 years from 2008-2015 were extracted from the electronic medical record system of the National University Hospital, Singapore...

Introduction: In this study, we aimed to identify the differences in sociodemographic variables and reasons for termination of pregnancy (TOP) between married women and single/divorced women. We hope that this study can guide future policies and interventions to reduce the incidence of unsupported pregnancies in this profile group of women. Methods: We retrospectively evaluated the sociodemographic data of 802 women who underwent an abortion for social reasons at our institution in Singapore from January 2016 to September 2018...

Paediatric brain tumours (PBTs) are the most common solid tumours in children. Previous publications reflect variations in incidence rates and frequency of histological types in different global populations. However, there are limited studies on the epidemiology of PBTs in Singapore. This study aims to summarise the epidemiology of paediatric brain tumours managed in Singapore. This is an ethics-approved retrospective study of all patients below 19 years old diagnosed with PBTs managed by Singapore's 2 tertiary paediatric neurosurgical centres, KK Women's and Children's Hospital (KKH) and the National University Hospital (NUH) over a 15-year period from 01 January 2002 to 31 December 2017...

BACKGROUND: Hepatocellular carcinoma (HCC) is a common primary liver cancer with poor overall survival. We hypothesized that there are HCC-associated cell-types that impact patient survival. METHODS: We combined liver single nucleus (snRNA-seq), single cell (scRNA-seq), and bulk RNA-sequencing (RNA-seq) data to search for cell-type differences in HCC. To first identify cell-types in HCC, adjacent non-tumor tissue, and normal liver, we integrated single-cell level data from a healthy liver cohort (n = 9 non-HCC samples) collected in the Strasbourg University Hospital; an HCC cohort (n = 1 non-HCC, n = 14 HCC-tumor, and n = 14 adjacent non-tumor samples) collected in the Singapore General Hospital and National University; and another HCC cohort (n = 3 HCC-tumor and n = 3 adjacent non-tumor samples) collected in the Dumont-UCLA Liver Cancer Center...

BACKGROUND: Contemporary data of peripheral T-cell lymphoma (PTCL) and natural-killer/T-cell lymphoma (NKTL) patients treated with ifosfamide, carboplatin and etoposide (ICE) are limited. AIMS: We performed a retrospective analysis to estimate outcomes of ICE-treated PTCL and NKTL patients at three tertiary cancer centres in Singapore. METHODS AND RESULTS: Patients were identified through lymphoma databases from National Cancer Centre Singapore (NCCS), National University Hospital, Singapore (NUHS), and Singapore General Hospital (SGH)...

Dyskeratosis congenita (DKC) is a genodermatosis of variable inheritance and is often characterised by the classical triad of nail dysplasia, reticulate hyperpigmentation of upper chest and neck, and oral leukoplakia. We report 2 cases of DKC from National University Hospital, Singapore, whose clinical presentations differed greatly from each other. Dermatologists should hold a high index of suspicion for DKC in young patients who present without the classical triad of features, as early dermatological care can be instituted through reinforcement of rigorous sun protection and regular surveillance for skin cancers...

Metastatic infection resulting from Klebsiella pneumoniae liver abscess (KPLA) results in high mortality and morbidity.
