Risk Perceptions of Health Care Workers and Occupational Health Experts on Psychological Distress: A Qualitative Mental Model Study.

Background: The objectives of this study are to explore healthcare workers' (HCWs') mental models regarding psychological distress and to compare these with that of experts.

Methods: Semistructured interviews were conducted (n = 28 HCWs, n = 13 experts). The topic list encompassed risk perception, early stress symptoms, causes, consequences, and preventive measures of psychological distress.

Surgeon Prioritization of Mental, Social, and Pathophysiological Aspects of Health Among People With Traumatic and Nontraumatic Musculoskeletal Conditions.

Background: There is mounting evidence that, among musculoskeletal patients, variation in capability has more notable associations with variations in mental and social health factors than with variation in pathophysiology severity. This study sought factors that could limit the integration of this evidence into more comprehensive care models.

Methods: In two scenario-based experiments, surgeon participants in an international collaborative, the Science of Variation Group, reviewed scenarios of (a) nontraumatic (83 participants) and (b) trauma-related (130 participants) pathophysiologies for which tests and treatments were discretionary.

Statistical groupings of mental and social health measurements correlate with musculoskeletal capability - A cross sectional study.

Objective: A better understanding of the degree to which social health factors contribute uniquely to statistical clusters associated with variation in levels of capability might inform targeted whole person care strategies for more comprehensive management of musculoskeletal health. Therefore, we asked: (1) What are the statistical groupings of social and mental health measurements in patients seeking specialty care for musculoskeletal conditions? (2) Do identified psychosocial groupings correspond with different mean magnitudes of incapability accounting for demographic and clinical factors?

Methods: We included 158 patients seeking musculoskeletal specialty care and collected measures of magnitude of incapability, unhelpful thoughts and distress regarding symptoms, symptoms of depression, symptoms of anxiety, and social health. A k-means clustering algorithm was fit to the data and a linear regression model compared mean PROMIS-PF CAT scores for grouping.

Effectiveness of L-serine supplementation in children with a loss-of-function mutation: Rationale and protocol for single patient (n-of-1) multiple cross-over trials.

Rationale: Loss-of-function (LoF) mutations in result in neurologic abnormalities due to -methyl-D-aspartate receptor (NMDAR) dysfunction. Affected persons present with various symptoms, including intellectual developmental disability (IDD), hypotonia, communication deficits, motor impairment, complex behavior, seizures, sleep disorders and gastrointestinal disturbance. Recently, experiments showed that D-serine mitigates function to GluN2B (mutation)-containing NMDARs.

Variations in 1-year Trajectories of Levels of Pain and Capability After Shoulder Arthroplasty Are Associated With Baseline Mental Health.

Background: There is variability in the trajectories of pain intensity and magnitude of incapability after shoulder arthroplasty. A better understanding of the degree to which variation in recovery trajectories relates to aspects of mental health can inform the development of comprehensive biopsychosocial care strategies.

Questions/purposes: (1) Do pain intensities at baseline and the trajectories during recovery differ between groups when stratified by mental health composite summary score, arthroplasty type, and revision surgery? (2) Do magnitudes of capability at baseline and the trajectories during recovery differ between these groups?

Methods: We used a registry of 755 patients who underwent shoulder arthroplasty by a single surgeon at a specialized urban orthopaedic hospital that recorded the mental component summary (MCS) score of the Veterans RAND 12, a measure of shoulder-specific comfort and capability (American Shoulder and Elbow Surgeons [ASES] score, which ranges from 0 to 100 points, with a score of 0 indicating worse capability and pain and 100 indicating better capability and pain and a minimum clinically important difference of 6.

Isolation: The experience of adolescent motherhood in Laos.

Background: Teenage pregnancy is a persistent public health problem with pervasive socio-economic consequences, particularly in in low- and middle-income countries, often related to low social participation and low economic security. The experiences of adolescent pregnancy and motherhood have seldom been described from a personal point of view. This study aimed to gain insights into how adolescent mothers in Laos experience their motherhood, how they perceive their situation and try to cope with it.

Risk factors of late lesion growth after acute ischemic stroke treatment.

Background: Even days after treatment of acute ischemic stroke due to a large vessel occlusion, the infarct lesion continues to grow. This late, subacute growth is associated with unfavorable functional outcome. In this study, we aim to identify patient characteristics that are risk factors of late, subacute lesion growth.

Alternative Randomized Trial Designs in Surgery: A Systematic Review.

Introduction: Randomized controlled trials (RCTs) yield the highest level of evidence but are notoriously difficult to perform in surgery. Surgical RCTs may be hampered by slow accrual, the surgical learning curve, and lack of financial support. Alternative RCT designs such as stepped-wedge randomized controlled trials (SW-RCTs), registry-based randomized controlled trials (RB-RCTs), and trials-within-cohorts (TwiCs) may overcome several of these difficulties.

No effects of siblings and twin testosterone transfer on autistic traits.

Background: Having twin and non-twin siblings might influence autistic traits both prenatally and postnatally. The twin testosterone transfer hypothesis suggests that girls with a twin brother are exposed to higher levels of prenatal testosterone than girls with a twin sister, and that increased testosterone exposure masculinizes neural development and increases autistic traits. Postnatally, siblings may provide example behaviour, which could reduce autistic traits.

The Role of Edema in Subacute Lesion Progression After Treatment of Acute Ischemic Stroke.

Ischemic lesions commonly continue to progress even days after treatment, and this lesion growth is associated with unfavorable functional outcome in acute ischemic stroke patients. The aim of this study is to elucidate the role of edema in subacute lesion progression and its influence on unfavorable functional outcome by quantifying net water uptake. We included all 187 patients from the MR CLEAN trial who had high quality follow-up non-contrast CT at 24 h and 1 week.

Posttreatment Ischemic Lesion Evolution Is Associated With Reduced Favorable Functional Outcome in Patients With Stroke.

Background And Purpose: Ischemic lesion volume can increase even 24 hours after onset of an acute ischemic stroke. In this study, we investigated the association of lesion evolution with functional outcome and the influence of successful recanalization on this association.

Methods: We included patients from the MR CLEAN trial (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands) who received good quality noncontrast CT images 24 hours and 1 week after stroke onset.

Clinical guidance for podiatrists in the management of foot problems in rheumatic disorders: evaluation of an educational programme for podiatrists using a mixed methods design.

Background: Foot and ankle problems are common in rheumatic disorders and often lead to pain and limitations in functioning, affecting quality of life. There appears to be large variability in the management of foot problems in rheumatic disorders across podiatrists. To increase uniformity and quality of podiatry care for rheumatoid arthritis (RA), osteoarthritis (OA), spondyloarthritis (SpA), and gout a clinical protocol has been developed.

Rationale and study protocol of the Physical Activity and Dietary intervention in women with OVArian cancer (PADOVA) study: a randomised controlled trial to evaluate effectiveness of a tailored exercise and dietary intervention on body composition, physical function and fatigue in women with ovarian cancer undergoing chemotherapy.

Introduction: As a consequence of ovarian cancer and its treatment, many women with ovarian cancer have to deal with reduced physical function, fatigue, and loss of weight and/or muscle mass, compromising quality of life. Exercise and dietary interventions can positively influence body composition, physical fitness and function, and fatigue in patients with cancer. However, there are no data from randomised controlled trials on the effectiveness of exercise and dietary interventions in patients with ovarian cancer.

Associations between sex hormones, sleep problems and depression: A systematic review.

Sleep problems and depression are both common and have a high impact on quality of life. They are also strongly associated and commonly occur together. During the reproductive age, both sleep problems and depression are almost twice as common in women than men.

Factors influencing sexual and reproductive health among adolescents in Lao PDR.

Background: Adolescents are particularly vulnerable to poor sexual and reproductive health outcomes. In addition, Lao PDR has the highest teenage pregnancy rate in southeast Asia and a high maternal mortality ratio.

Objective: This study aimed to provide a comprehensive exploration of factors that influence SRH knowledge, attitudes, and practices of adolescents in Bokeo Province, Lao PDR.

Quality of family planning services for women of reproductive age in Lao PDR.

Background: In Lao PDR, 15% of the married women want to postpone or prevent having a child, yet most are not using contraceptives to achieve this. Literature shows that usage of contraceptives is strongly dependent on the quality of family planning services. However, little is known about the quality of family planning services in Lao PDR.

Effective Information Provision About the Side Effects of Treatment for Malignant Lymphoma: Protocol of a Randomized Controlled Trial Using Video Vignettes.

Background: Informing patients with cancer about the possible implications of prospective treatment is a crucial yet challenging task. Unfortunately, patients' recall of medical information is generally poor and their information needs are not met. Effective information giving entails that oncologists help patients understand and recall the implications of their treatment, meanwhile fostering a trusting physician-patient relationship.

Feedback-informed treatment in emergency psychiatry; a randomised controlled trial.

Background: Immediate patient feedback has been shown to improve outcomes for patients in mild distress but it is unclear whether psychiatric patients in severe distress benefit equally from feedback. This study investigates the efficacy of an immediate feedback instrument in the treatment of patients with acute and severe psychosocial or psychiatric problems referred in the middle of a crisis.

Methods: A naturalistic mixed diagnosis sample of patients (N = 370) at a Psychiatric Emergency Centre was randomised to a Treatment-as-Usual (TAU) or a Feedback (FB) condition.

Escherichia coli MTC, a human NADPH P450 reductase competent mutagenicity tester strain for the expression of human cytochrome P450 isoforms 1A1, 1A2, 2A6, 3A4, or 3A5: catalytic activities and mutagenicity studies.

We report here on the genetic engineering of four new Escherichia coli tester bacteria, coexpressing human CYP1A1, CYP2A6, CYP3A4 or CYP3A5 with human NADPH cytochrome P450 reductase (RED) by a biplasmid coexpression system, recently developed to express human CYP1A2 in the tester strain MTC. The four new strains were compared for CYP- and RED-expression levels and CYP activities with the formerly developed CYP1A2 expressing strain. CYP1A2 and CYP2A6 were expressed at the highest, CYP1A1 at the lowest and CYP3A4 and CYP3A5 at intermediate expression levels.

Affinity purification of GTPase proteins from oat root plasma membranes using biotinylated GTP.

Biotinylated GTP was synthesized and it was demonstrated that this ligand was bi-functional: it competed with [3H]Gpp(NH)p for binding to membrane proteins and it bound to immobilized avidin. Peripheral plasma membrane proteins were solubilized in a low-salt wash, incubated with GTP-biotin and biotinylated proteins were coupled to an avidin column. Elution with excess biotin yielded 10 polypeptides as seen with a silver stained SDS-PAGE gel.
