The first 100 days after childbirth: cross-sectional study of maternal clinical events and health needs from primary care.

Background: The first 100 days after childbirth are important for women recovering from pregnancy and birth.

Aim: To describe the most common clinical events or health needs documented in women's primary care records in the first 100 days after childbirth.

Design And Setting: Cross-sectional study using electronic health records from UK primary care data.

The Impact of Social Media Use Interventions on Mental Well-Being: Systematic Review.

Background: There is some evidence that more social media use is related to poorer mental well-being and that social media use can become problematic when it starts to interfere with a person's daily life and mental well-being. To address this issue and improve users' mental well-being, social media use interventions (eg, abstinence from social media) have been developed and evaluated. However, there is limited understanding of the effectiveness of these interventions in improving mental well-being.

Association of Recent Fatherhood With Antidepressant Treatment Initiation Among Men in the United Kingdom.

Importance: There is some evidence that men may be at higher risk of depression directly following the birth of their child and that approximately 1 in 10 men will experience depression in the year after birth, but less is known about men's antidepressant treatment during this time. Likewise, few direct comparisons have been made with antidepressant treatment in men who have not recently become fathers.

Objectives: To determine whether recently having a child was associated with increased odds of antidepressant treatment in men.

Prevalence of Perinatal Depression and Anxiety in Both Parents: A Systematic Review and Meta-analysis.

Importance: New and expectant parents experience perinatal mood disorders, with consequences to parenting ability, bonding with the neonate, interpersonal relationships, and health and well-being of parents. Research shows that maternal and paternal perinatal mood disorders are associated, but no recent systematic review has addressed the prevalence of perinatal mood disorders in both mothers and fathers (parental dyad).

Objective: To examine the prevalence of perinatal mood disorders in parental dyads and identify factors associated with perinatal mood disorders in parental dyads.

Supportive care needs of men with prostate cancer: A systematic review update.

Background: Prostate cancer is highly prevalent and impacts profoundly on patients' quality of life, leading to a range of supportive care needs.

Methods: An updated systematic review and thematic synthesis of qualitative data using the Preferred Reporting Items for Systematic Reviews (PRISMA) reporting guidelines, to explore prostate cancer patients' experience of, and need for, supportive care. Five databases (Medline, Embase, PsycInfo, Emcare and ASSIA) were searched; extracted data were synthesised using Corbin and Strauss's 'Three Lines of Work' framework.

Hypertension and cardiovascular risk factor management in a multi-ethnic cohort of adults with CKD: a cross sectional study in general practice.

Background: Hypertension, especially if poorly controlled, is a key determinant of chronic kidney disease (CKD) development and progression to end stage renal disease (ESRD).

Aim: To assess hypertension and risk factor management, and determinants of systolic blood pressure control in individuals with CKD and hypertension.

Design And Setting: Cross-sectional survey using primary care electronic health records from 47/49 general practice clinics in South London.

Using Virtual Patients to Explore the Clinical Reasoning Skills of Medical Students: Mixed Methods Study.

Background: Improving clinical reasoning skills-the thought processes used by clinicians to formulate appropriate questions and diagnoses-is essential for reducing missed diagnostic opportunities. The electronic Clinical Reasoning Educational Simulation Tool (eCREST) was developed to improve the clinical reasoning of future physicians. A feasibility trial demonstrated acceptability and potential impacts; however, the processes by which students gathered data were unknown.

[Prospective Cohort Study of In-Hospital Patients Undergoing Ophthalmic Surgery for the Validation of ClassIntra: Classification of Intraoperative Adverse Events].

Background: To the best of our knowledge, there is no validated classification to assess intraoperative adverse events (iAEs) in ophthalmic surgery. ClassIntra is a newly developed classification for surgery- and anaesthesia-related iAEs that has been recently validated in various surgical disciplines, but not in ophthalmic surgery. We aim to assess the validity and practicability of ClassIntra in patients undergoing ophthalmic surgery.

Online patient simulation training to improve clinical reasoning: a feasibility randomised controlled trial.

Background: Online patient simulations (OPS) are a novel method for teaching clinical reasoning skills to students and could contribute to reducing diagnostic errors. However, little is known about how best to implement and evaluate OPS in medical curricula. The aim of this study was to assess the feasibility, acceptability and potential effects of eCREST - the electronic Clinical Reasoning Educational Simulation Tool.

The possible clinical predictors of fatigue in Parkinson's disease: a study of 135 patients as part of international nonmotor scale validation project.

Fatigue is a common yet poorly understood and underresearched nonmotor symptom in Parkinson's disease. Although fatigue is recognized to significantly affect health-related quality of life, it remains underrecognised and empirically treated. In this paper, the prevalence of fatigue as measured by a validated visual analogue scale and the Parkinson's disease nonmotor symptoms scale (PDNMSS) was correlated with other motor and nonmotor comorbidities.

Seeing the bigger picture: training in perspective broadening reduces self-reported affect and psychophysiological response to distressing films and autobiographical memories.

Appraising negative experiences in ways that reduce associated distress is a key component of successful emotion regulation. In 4 studies, the authors examined the effects of systematically practicing appraisal skills using a computer-mediated cognitive bias modification (CBM) methodology. In Studies 1-3, healthy participants practiced applying appraisal themes linked to the idea of seeing the bigger picture to a series of distressing training films, either during each film (Study 1) or immediately after each film (Studies 2 and 3).

Structural biology: analysis of 'downhill' protein folding.

There is controversy as to whether homologues from the peripheral subunit binding domain family of small proteins fold 'downhill' (that is, non-cooperatively, in the absence of free-energy barriers between conformations) and whether they modulate their size for biological function. Sadqi et al. claim that Naf-BBL--a naphthylalanine-labelled, truncated version of this domain--folds in this way, on the grounds that they recorded a wide spread of melting temperatures of individual atoms measured by proton nuclear magnetic resonance (NMR) during their thermal denaturation.

Reduced specificity of autobiographical memories following a negative mood induction.

Reduced autobiographical memory specificity (AMS) to emotional and neutral cue words appears to be a stable cognitive marker of clinical depression. For example, reduced AMS is present in remitted/recovered depressed patients and shows no reliable relationship with current levels of depressed mood in correlational studies. The present study examined whether reduced AMS could be induced in healthy volunteers with no history of depression, using a negative mood manipulation and whether levels of AMS and induced mood were positively correlated.

Ultra-fast barrier-limited folding in the peripheral subunit-binding domain family.

We have determined the solution structures, equilibrium properties and ultra-fast folding kinetics for three bacterial homologues of the peripheral subunit-binding domain (PSBD) family. The mesophilic homologue, BBL, was less stable than the thermophilic and hyper-thermophilic variants (E3BD and POB, respectively). The broad unfolding transitions of each PSBD, when probed by different techniques, were essentially superimposable, consistent with co-operative denaturation.

Investigation of the catalytic triad of arylamine N-acetyltransferases: essential residues required for acetyl transfer to arylamines.

The NATs (arylamine N-acetyltransferases) are a well documented family of enzymes found in both prokaryotes and eukaryotes. NATs are responsible for the acetylation of a range of arylamine, arylhydrazine and hydrazine compounds. We present here an investigation into the catalytic triad of residues (Cys-His-Asp) and other structural features of NATs using a variety of methods, including site-directed mutagenesis, X-ray crystallography and bioinformatics analysis, in order to investigate whether each of the residues of the catalytic triad is essential for catalytic activity.

One-state downhill versus conventional protein folding.

Classical protein folding invokes a cooperative transition between distinct thermodynamic states that are individually populated at equilibrium and separated by an energy barrier. It has been proposed, however, that the small protein, BBL, undergoes one-step downhill folding whereby it folds non-cooperatively to its native state without encountering an appreciable energy barrier. Only a single conformational ensemble is populated under given conditions, and so the denatured state ensemble progressively changes into the native structure.

Evidence towards the role of arylamine N-acetyltransferase in Mycobacterium smegmatis and development of a specific antiserum against the homologous enzyme of Mycobacterium tuberculosis.

Arylamine N-acetyltransferase (NAT) in humans inactivates the anti-tubercular drug isoniazid (INH). Homologues of human NAT are present in Mycobacterium tuberculosis and Mycobacterium smegmatis, where they can acetylate, and hence inactivate, INH. The in vivo role of mycobacterial NAT is not known but heterologous expression of the M.
