Heart disease is one of the largest burdens to human health worldwide and has very limited therapeutic options. Engineered three-dimensional (3D) vascularized cardiac tissues have shown promise in rescuing cardiac function in diseased hearts and may serve as a whole organ replacement in the future. One of the major obstacles in reconstructing these thick myocardial tissues to a clinically applicable scale is the integration of functional vascular networks capable of providing oxygen and nutrients throughout whole engineered constructs. selleck chemicals Without perfusion of oxygen and nutrient flow throughout the entire engineered tissue not only is tissue viability compromised, but also overall tissue functionality is lost. There are many supporting technologies and approaches that have been developed to create vascular networks such as 3D bioprinting, co-culturing hydrogels, and incorporation of soluble angiogenic factors. In this state-of-the-art review, we discuss some of the most current engineered vascular cardiac tissues reported in the literature and future directions in the field.Metformin is an effective drug against type 2 diabetes (T2D), a pathogenesis in which mitochondrial dysfunction is one of the main players. Thus, our first aim was to describe the effect of metformin on mitochondrial function in an outpatient population with T2D. For analyzing this hypothesis, we performed a preliminary cross-sectional study complying with the STROBE requirements. We studied leukocytes from 139 healthy controls, 39 T2D patients without metformin treatment, and 81 T2D patients who had been on said treatment for at least 1 year. Leukocytes from T2D patients displayed higher total and mitochondrial reactive oxygen species levels, lower mitochondrial membrane potential, and lower oxygen consumption. Moreover, their mitochondria expressed lower mRNA and protein levels of fusion proteins mitofusin-1 (MFN1), mitofusin-2 (MFN2), and optic atrophy 1 (OPA1), and higher protein and gene expression levels of mitochondrial fission protein 1 (FIS1) and dynamin-related protein 1 (DRP-1). In addition, we observed enhanced leukocyte/endothelial interactions in T2D patients. Metformin reversed most of these effects, ameliorating mitochondrial function and dynamics, and reducing the leukocyte/endothelial interactions observed in T2D patients. These results raise the question of whether metformin tackles T2D by improving mitochondrial dysfunction and regulating mitochondrial dynamics. Furthermore, it would seem that metformin modulates the alteration of interactions between leukocytes and the endothelium, a subclinical marker of early atherosclerosis.

The relations of childhood emotional maltreatment and alexithymia to the clinical course of bipolar disorder (BD) have been widely recognised. Difficulties in regulating emotions may explain these relationships. The current study evaluated the effects of childhood emotional maltreatment and alexithymia on depressive and manic symptoms as well as suicidal ideation in female patients with BD. Emotion dysregulation was evaluated as a mediating factor.

Three hundred hospitalised female patients with a diagnosis of BD provided information regarding their history of childhood emotional maltreatment, alexithymia, difficulties in emotion regulation, depressive and manic symptoms, and suicidal ideation. A series of structural equation models (SEMs) were calculated to assess the associations between these variables.

Childhood emotional abuse and difficulty in identifying feelings were indirectly associated with depressive and manic symptoms as well as suicidal ideation. This association was mediated by emotion dys that patients with BD who experienced emotional abuse during childhood and have difficulties identifying emotions report greater emotion dysregulation. These individuals, in turn, are more likely to experience more severe depressive and manic symptoms as well as suicidal ideation.Key pointsChildhood emotional maltreatment and emotional and clinical factors in bipolar disorder were assessed.Childhood emotional abuse indirectly affected clinical factors via emotion dysregulation.Difficulty in identifying feelings was linked to clinical factors via emotional dysregulation.Emotional dysregulation affected the links of childhood emotional maltreatment and difficulty in identifying feelings on suicidal ideation after controlling for clinical symptoms.Emotional dysregulation dimensions of impulse, strategies, and goals emerge in relation to suicidal ideation.

Sense of coherence (SOC) is a personal resource that allows people to stay healthy in spite of stressful situations. SOC is known to be low in eating disorders. We explored whether SOC correlated with anorexia nervosa (AN) symptoms several years after initial hospitalization for AN, to inform us whether AN treatment concepts could more specifically focus on increasing SOC.

Former patients were contacted 5-11 years after hospitalization for AN in a German integrative medicine hospital. Participants completed the Eating Disorder Inventory (EDI-2) and the SOC Questionnaire (SOC-13). Hospital records were reviewed. Correlations between EDI-2 subscales and SOC-13 were tested. A t-test was conducted to assess the difference between the SOC-13 and the norm. A median split was performed, dividing SOC scores into two groups and comparing these with EDI-2 subscales.

Of 149 previously hospitalized female patients, 83 could be contacted and 68 agreed to participate (46%). 17.6% self-reported that they currently suffered from an eating disorder. The mean follow-up time was 7.2 years. All EDI-2 subscales correlated negatively with the SOC-13 score (

 < .01). The mean SOC was significantly lower than the norm (

 < .001). In the median split, the lower SOC group had significantly higher scores on all EDI-2 subscales.

Amongst previously hospitalized AN patients, the SOC was lower than a normative sample and correlated with on-going eating disorder symptoms in long-term follow-up. Strengthening SOC as a personal resource should be incorporated as a specific goal in AN treatment and its impact on long-term outcomes evaluated.
