Poor HIV-related Knowledge, Perceived Risks and Attitudes Among Urban-dwelling Malaysian Older Adults: Key Barriers to Zero HIV Transmission by 2030.

Globally and in Malaysia, there are increasing rates of HIV infection among older adults but a corresponding decline in other younger age groups. We aimed to investigate the HIV-related knowledge, perceived risks, attitudes, and risk behaviours among multi-ethnic urban-dwelling older adults in Malaysia. A cross-sectional, questionnaire-based study was conducted among 320 adults aged 50 years and above residing in urban Klang Valley, Malaysia.

Lipidomic Profiling of Lung Pleural Effusion Identifies Unique Metabotype for EGFR Mutants in Non-Small Cell Lung Cancer.

Cytology and histology forms the cornerstone for the diagnosis of non-small cell lung cancer (NSCLC) but obtaining sufficient tumour cells or tissue biopsies for these tests remains a challenge. We investigate the lipidome of lung pleural effusion (PE) for unique metabolic signatures to discriminate benign versus malignant PE and EGFR versus non-EGFR malignant subgroups to identify novel diagnostic markers that is independent of tumour cell availability. Using liquid chromatography mass spectrometry, we profiled the lipidomes of the PE of 30 benign and 41 malignant cases with or without EGFR mutation.
