White matter microstructure in obesity and bipolar disorders: an ENIGMA bipolar disorder working group study in 2186 individuals.

Although specific risk factors for brain alterations in bipolar disorders (BD) are currently unknown, obesity impacts the brain and is highly prevalent in BD. Gray matter correlates of obesity in BD have been well documented, but we know much less about brain white matter abnormalities in people who have both obesity and BD. We obtained body mass index (BMI) and diffusion tensor imaging derived fractional anisotropy (FA) from 22 white matter tracts in 899 individuals with BD, and 1287 control individuals from 20 cohorts in the ENIGMA-BD working group.

Principal component analysis as an efficient method for capturing multivariate brain signatures of complex disorders-ENIGMA study in people with bipolar disorders and obesity.

Multivariate techniques better fit the anatomy of complex neuropsychiatric disorders which are characterized not by alterations in a single region, but rather by variations across distributed brain networks. Here, we used principal component analysis (PCA) to identify patterns of covariance across brain regions and relate them to clinical and demographic variables in a large generalizable dataset of individuals with bipolar disorders and controls. We then compared performance of PCA and clustering on identical sample to identify which methodology was better in capturing links between brain and clinical measures.

Persuasive COVID-19 vaccination campaigns on Facebook and nationwide vaccination coverage in Ukraine, India, and Pakistan.

Social media platforms have a wide and influential reach, and as such provide an opportunity to increase vaccine uptake. To date, there is no large-scale, robust evidence on the offline effects of online messaging campaigns. We aimed to test whether pre-tested, persuasive messaging campaigns from UNICEF, disseminated on Facebook, influenced COVID-19 vaccine uptake in Ukraine, India, and Pakistan.

Baseline long-term potentiation-like cortical plasticity is associated with longitudinal cortical thinning in healthy adults and in adults with bipolar disorder type II.

The precise neurobiological processes underlying cerebral cortical thinning in aging and psychiatric illnesses remain undetermined, yet aging- and synaptic dysfunction-related loss of synapses are potentially important mechanisms. We used long-term potentiation-like plasticity of the visual evoked potential as an index of synaptic function in the cortex and hypothesized that plasticity at baseline would be negatively associated with future cortical thinning in healthy adults and in adults with bipolar disorder type II. Thirty-two healthy adults and 15 adults with bipolar disorder type II underwent electroencephalography-based measurement of visual evoked potential plasticity and 3T magnetic resonance imaging of the brain at baseline and a follow-up brain scan on average 2.

Effect of mobile phone-based health insurance contribution payment system on retention of coverage in the National Health Insurance Scheme in Ghana: an evaluation study.

Background: Ghana introduced a mobile phone-based contribution payment system in its national health insurance scheme (NHIS) in December 2018 to improve the process of enrolment. We evaluated the effect of this digital health intervention on retention of coverage in the Scheme, one year after its implementation.

Methods: We used NHIS enrolment data for the period, 1 December 2018-31 December 2019.

COVID-19-related consultation-liaison (CL) mental health services in general hospitals: A perspective from Europe and beyond.

Objective: The COVID-19 pandemic posed new challenges for integrated health care worldwide. Our study aimed to describe newly implemented structures and procedures of psychosocial consultation and liaison (CL) services in Europe and beyond, and to highlight emerging needs for co-operation.

Methods: Cross-sectional online survey from June to October 2021, using a self-developed 25-item questionnaire in four language versions (English, French, Italian, German).

Systemic Cell Adhesion Molecules in Severe Mental Illness: Potential Role of Intercellular CAM-1 in Linking Peripheral and Neuroinflammation.

Background: Cell adhesion molecules (CAMs) orchestrate leukocyte trafficking and could link peripheral and neuroinflammation in patients with severe mental illness (SMI), by promoting inflammatory and immune-mediated responses and mediating signals across blood-brain barrier. We hypothesized that CAMs would be dysregulated in SMI and evaluated plasma levels of different vascular and neural CAMs. Dysregulated CAMs in plasma were further evaluated in vivo in leukocytes and brain tissue and in vitro in induced pluripotent stem cells.

Lower circulating neuron-specific enolase concentrations in adults and adolescents with severe mental illness.

Background: Both neurodegenerative and neurodevelopmental abnormalities have been suggested to be part of the etiopathology of severe mental illness (SMI). Neuron-specific enolase (NSE), mainly located in the neuronal cytoplasm, may indicate the process as it is upregulated after neuronal injury while a switch from non-neuronal enolase to NSE occurs during neuronal maturation.

Methods: We included 1132 adult patients with SMI [schizophrenia (SZ) or bipolar spectrum disorders], 903 adult healthy controls (HC), 32 adolescent patients with SMI and 67 adolescent HC.

Increased circulating IL-18 levels in severe mental disorders indicate systemic inflammasome activation.

Background: Schizophrenia (SCZ) and bipolar disorder (BD) are severe mental illnesses (SMI) that are part of a psychosis continuum, and dysregulated innate immune responses have been suggested to be involved in their pathophysiology. However, disease-specific immune mechanisms in SMI are not known yet. Recently, dyslipidemia has been linked to systemic inflammasome activation, and elevated atherogenic lipid ratios have been shown to correlate with circulating levels of inflammatory biomarkers in SMI.

Plasma Levels of the Cytokines B Cell-Activating Factor (BAFF) and A Proliferation-Inducing Ligand (APRIL) in Schizophrenia, Bipolar, and Major Depressive Disorder: A Cross Sectional, Multisite Study.

Background: Immune dysfunction has been implicated in the pathogenesis of schizophrenia and other nonaffective psychosis (SCZ), bipolar spectrum disorder (BIP) and major depressive disorder (MDD). The cytokines B cell-activating factor (BAFF) and A proliferation-inducing ligand (APRIL) belong to the tumor necrosis factor (TNF) super family and are essential in orchestrating immune responses. Abnormal levels of BAFF and APRIL have been found in autoimmune diseases with CNS affection.

Patient selection for islet or solid organ pancreas transplantation: experiences from a multidisciplinary outpatient-clinic approach.

Objective: β-cell replacement therapy (βCRT), including pancreas transplantation alone (PTA) and islet transplantation (ITX), is a treatment option for selected type 1 diabetes patients. All potential candidates for βCRT in Norway are referred to one national transplant centre for evaluation before any pre-transplant workup is started. This evaluation was performed by a transplant nephrologist alone prior to 2015 and by a multidisciplinary team (MDT) from 2015.

Traumatic stress, mental health, and quality of life in adolescents with esophageal atresia.

Introduction: We aimed to investigate QoL in EA patients in relation to comparison groups and to clinical factors including experienced traumatic stress.

Material And Methods: Adolescents with EA in Norway born between 1996 and 2002 were included. Clinical assessment and patient's characteristics were collected.

The genetic architecture of human brainstem structures and their involvement in common brain disorders.

Brainstem regions support vital bodily functions, yet their genetic architectures and involvement in common brain disorders remain understudied. Here, using imaging-genetics data from a discovery sample of 27,034 individuals, we identify 45 brainstem-associated genetic loci, including the first linked to midbrain, pons, and medulla oblongata volumes, and map them to 305 genes. In a replication sample of 7432 participants most of the loci show the same effect direction and are significant at a nominal threshold.

Borderline patients have difficulties describing feelings; bipolar II patients describe difficult feelings. An alexithymia study.

Objective: Apparent similarities between borderline personality disorder (BPD) and bipolar II disorder (BIP-II) contribute to clinical difficulties in distinguishing between the disorders. Here, we aimed to explore how subjective Difficulties with the Identification and Description of Feelings (DIDF), a major constituent of the alexithymia construct and assessed as a part of the Toronto Alexithymia Scale (TAS), are related to relationship problems and health complaints in these groups.

Methods: Twenty-two patients with BPD; 22 patients with BIP-II; and 23 healthy controls (HC) completed TAS.

Supraventricular tachycardia of the sick, a unique entity.

Objective: This study explored a unique form of atrioventricular nodal reentrant tachycardia (AVNRT) in which certain acutely ill patients have a first episode of supraventricular tachycardia (SVT) with a short RP interval.

Methods: A retrospective chart review was conducted of patients at a single institution who developed SVT with short RP and yielded 19 patients.

Results: None of the 19 patients had a prior history of AVNRT or any other arrhythmia.

Mood episodes are associated with increased cortical thinning: A longitudinal study of bipolar disorder type II.

Objectives: Previous studies found evidence for thinner frontotemporal cortices in bipolar disorder (BD), yet whether this represents a stable disease trait or an effect of mood episodes remains unknown. Here, we assessed the reproducibility of thinner frontotemporal cortices in BD type II, compared longitudinal changes in cortical thickness between individuals with BD type II and healthy controls (HCs), and examined the effect of mood episodes on cortical thickness change.

Methods: Thirty-three HCs and 29 individuals with BD type II underwent 3T magnetic resonance imaging at baseline, as published previously, and 2.

Optimizing the Approach to Patients With Pleural Effusion and Radiologic Findings Suspect for Cancer.

Background: When patients present with pleural effusion and structural abnormalities consistent with malignancy on imaging, the traditional approach has been to perform a thoracentesis and await the results before proceeding to more invasive diagnostic procedures. The objective of this study was to evaluate whether concurrent thoracentesis and tissue biopsy is superior to sequential sampling.

Methods: Retrospective chart review was performed for patients who had a pleural cytology from May 2014 until January 2017.

Longitudinal and cross-sectional investigations of long-term potentiation-like cortical plasticity in bipolar disorder type II and healthy individuals.

Visual evoked potential (VEP) plasticity is a promising assay for noninvasive examination of long-term potentiation (LTP)-like synaptic processes in the cerebral cortex. We conducted longitudinal and cross-sectional investigations of VEP plasticity in controls and individuals with bipolar disorder (BD) type II. VEP plasticity was assessed at baseline, as described previously (Elvsåshagen et al.

Impact of targeted educational interventions on appropriateness of stress ulcer prophylaxis in critically ill adults.

Background: Acid suppression therapy (AST) is routinely used in critically ill patients to prevent stress-related mucosal bleeding (SRMB).

Objective: Our objective was to determine the impact of a structured educational intervention on AST used for prevention of SRMB on appropriateness of AST.

Methods: A single-center, retrospective, cohort study of appropriate use of AST in critically ill patients admitted to the medical intensive care unit (ICU) at an academic medical center between January to June of 2014 (no intervention) and January to June of 2015 (intervention) was conducted.

Impact of Targeted Educational Interventions on Clostridium difficile Infection Treatment in Critically Ill Adults.

Clostridium difficile infection (CDI) is a growing clinical and economic burden throughout the world. Pharmacists often are members of the primary care team in the intensive care unit (ICU) setting; however, the impact of pharmacists educating other health care providers on appropriateness of CDI treatment has not been previously examined. This study was performed to determine the impact of structured educational interventions on CDI treatment on appropriateness of CDI treatment and clinical outcomes.

Dentate gyrus-cornu ammonis (CA) 4 volume is decreased and associated with depressive episodes and lipid peroxidation in bipolar II disorder: Longitudinal and cross-sectional analyses.

Objectives: Reduced dentate gyrus volume and increased oxidative stress have emerged as potential pathophysiological mechanisms in bipolar disorder. However, the relationship between dentate gyrus volume and peripheral oxidative stress markers remains unknown. Here, we examined dentate gyrus-cornu ammonis (CA) 4 volume longitudinally in patients with bipolar II disorder (BD-II) and healthy controls and investigated whether BD-II is associated with elevated peripheral levels of oxidative stress.
