Prevalence of depression and anxiety in older people in low- and middle- income countries in Africa, Asia and South America: A systematic review and meta-analysis.

Background: There is rapid growth of older people in Low- and Middle- Income Countries (LMICs). The aim of this review was to assess the literature on prevalence of anxiety and depression in this demographic, which to our knowledge, has not yet been conducted.

Methods: Databases including Medline, PsychInfo, Embase, Scielo and African Journals Online were searched for terms including "mental disorders", "neurotic disorders", "mood disorders" and "anxiety disorders".

Trends in referrals to liaison psychiatry teams from UK emergency departments for patients over 65.

Introduction: The number of people over the age of 65 attending Emergency Departments (ED) in the United Kingdom (UK) is increasing. Those who attend with a mental health related problem may be referred to liaison psychiatry for assessment. Improving responsiveness and integration of liaison psychiatry in general hospital settings is a national priority.

Effect of laser power on force constant and phonon lifetime of stretching and bending vibration of Cu-doped WO nanostructures.

The influence of Cu-doping on their structural, vibrational and morphological properties of hydrothermally prepared Cu-doped WO has been studied. X-ray Diffraction studies confirm the tetragonal structure of WO and lower angle shift in doped samples indicates the incorporation of Cu in tungsten sites. Field emission scanning electron microscopy (FESEM) images exhibit micro rod-like morphology of the as-synthesized WO materials shows microstructure with rod-like projections slowly changes into nanorods and plates for doped samples.
