Background: The prevalence and prognosis of post-acute stage SARS-CoV-2 infection fatigue symptoms remain largely unknown.

Aims: We performed a systematic review to evaluate the prevalence of fatigue in post-recovery from SARS-CoV-2 infection.

Method: Medline, Embase, PsycINFO, CINAHL, Web of Science, Scopus, trial registries, Cochrane Central Register of Controlled Trials, and Google Scholar were searched for studies on fatigue in samples that recovered from polymerase chain reaction (PCR) diagnosed COVID-19.

Aims: An association between antibody deficiency and clozapine use in individuals with schizophrenia has recently been reported. We hypothesised that if clozapine-associated hypogammaglobulinaemia was clinically relevant this would manifest in referral patterns.

Methods: Retrospective case note review of patients referred and assessed by Immunology Centre for Wales (ICW) between January 2005 and July 2018 with extraction of clinical and immunological features for individuals with diagnosis of schizophrenia-like illness.

Background: The National Institute for Health and Clinical Excellence (NICE) guidance recommends Cognitive Behavioural Therapy (CBT) as part of multidisciplinary occupational mental health interventions for people with long-term or recurrent short-term sickness absence from work (NICE, 2009). Despite this, there is a paucity of data for both randomised trials for CBT and literature that supports the transferability of CBT into occupational environments.

Aims: This service evaluation aimed to evaluate the clinical effectiveness of CBT by analysing data from a partnership scheme between a local authority and a local heath board using a routine employee population.

Objective: We aimed to elucidate whether schizophrenia and type II diabetes mellitus may present with associated illness severity, in light of accumulating evidence to suggest both conditions have important shared inflammatory components with many shared inflammatory genetic factors.

Methods: We conducted a systematic review employing PRISMA criteria, searching EMBASE, Ovid MEDLINE, PsychInfo, Web of Science and Google Scholar to February 1st, 2017, for clinical studies assessing schizophrenia severity alongside dysglycaemia. A narrative synthesis was employed to discuss and compare findings between studies.

These features of delirium trials warrant special statistical attention; implications for each stage of a trial planning process are described.

Methods: Choice of outcome, patient sample, and data collection in delirium trials are discussed.

Methods: We conducted a literature search of Medline, Embase, PsychInfo, and Cochrane Review databases, which included both prospective and retrospective clinical trials and case studies on delirium and drug therapy in adult patients up to March 2008.
