[Effect of face mask type on trust attribution and doctor- patient relationship].

Background: The COVID-19 pandemic led to the wearing of face masks by both psychiatric care workers and patients. Despite their protection against transmission, negative effects - related to mask wearing - on the doctor-patient relationship are reported, which may be more severe in psychiatric patients.

Aim: Previous studies did not distinguish between face mask types.

All quiet on the western front? The evolutionary history of monogeneans (Dactylogyridae: Cichlidogyrus, Onchobdella) infecting a West and Central African tribe of cichlid fishes (Chromidotilapiini).

Owing to the largely unexplored diversity of metazoan parasites, their speciation mechanisms and the circumstances under which such speciation occurs - in allopatry or sympatry - remain vastly understudied. Cichlids and their monogenean flatworm parasites have previously served as a study system for macroevolutionary processes, e.g.

Gene-based interaction analysis shows GABAergic genes interacting with parenting in adolescent depressive symptoms.

Background: Most gene-environment interaction studies (G × E) have focused on single candidate genes. This approach is criticized for its expectations of large effect sizes and occurrence of spurious results. We describe an approach that accounts for the polygenic nature of most psychiatric phenotypes and reduces the risk of false-positive findings.

Depressive symptoms in adolescence: The role of perceived parental support, psychological control, and proactive control in interaction with 5-HTTLPR.

Background: Parenting dimensions are associated with depressive symptoms in adolescents. We investigated the role of perceived parenting dimensions and gene-environment interactions between these perceived parenting dimensions and five well-known variable number of tandem repeats (VNTRs): 5-HTTLPR, STin2, DAT1, DRD4, and MAO-A, in depressive symptoms.

Methods: From a non-clinical sample of 1111 Belgian adolescents (mean age: 13.

Genetic Evaluation of Schizophrenia Using the Illumina HumanExome Chip.

Introduction: Schizophrenia is a genetically heterogeneous disorder that is associated with several common and rare genetic variants. As technology involved, cost advantages of chip based genotyping was combined with information about rare variants, resulting in the Infinium HumanExome Beadchip. Using this chip, a sample of 493 patients with schizophrenia or schizoaffective disorder and 484 healthy controls was genotyped.
