Background: In cardiac patients positive affect has found to be associated with improved clinical outcomes, with reduced inflammation being one of the potential mechanisms responsible.
Methods: Positive affect was assessed using The Global Mood Scale (GMS), Positive and Negative Affect Schedule (PANAS), and Hospital Anxiety and Depression Scale (HADS) in patient with chronic heart failure (N=210; 67 ± 9 years, 79% men). Markers of inflammation (TNFα, sTNFr1, sTNFr2, IL-6 and CRP) were measured and averaged at three consecutive time points.
Results: The positive affect dimensions of the GMS and PANAS were significantly associated with lower averaged levels of sTNFr2, TNFα and IL-6 (p<.1), even after adjustment for clinical and lifestyle confounders. Positive affect of the HADS was significantly associated with lower averaged levels of hsCRP (p<.1), but was no longer significant after correction for lifestyle confounders and depressive symptoms.
Conclusion: Positive affect is associated with reduced inflammation in patients with heart failure.

Objective: Retroperitoneal fibrosis (RPF) is a rare condition marked by inflammation and fibrosis affecting the peritoneal and retroperitoneal soft tissues. In recent years, the identification of IgG4-related diseases has brought to light a significant association with fibrous disorders, including RPF, which were once considered independent. In this comprehensive cohort study, we performed a comparative analysis of the demographic, clinical, laboratory, histopathological, and therapeutic characteristics between patients with IgG4-related RPF and those with idiopathic retroperitoneal fibrosis (iRPF).

Cholangiocarcinoma (CCA), a highly aggressive form of cancer, is known for its high mortality rate. A Disintegrin and Metalloprotease Domain-like Protein Decysin-1 (ADAMDEC1) can promote the development and metastasis in various tumors by degrading the extracellular matrix. However, its regulatory mechanism in CCA remains unclear.

Given the significant prevalence of adverse childhood experiences (ACEs) and their detrimental impact on mental health, this study examines the relationship between attachment anxiety, attachment avoidance, and complex post-traumatic stress disorder (CPTSD) among college students with ACEs, emphasizing the mediating role of self-compassion (SC). A sample of 32,388 students from Kunming, China completed a survey including the Revised Adverse Childhood Experiences Questionnaire (ACEQ-R), the Adult Attachment Scale (AAS), the International Trauma Questionnaire (ITQ), and the Self-Compassion Scale-Short Form (SCS-SF). Among the participants, 3,896 reported at least one ACE.

Bovine viral diarrhea (BVD) is a highly infectious disease affecting cattle, leading to significant economic losses in many countries engaged in cattle production. From February 2022 to October 2022, a study was conducted to determine the seroprevalence and associated risk factors of Bovine Viral Diarrhea Virus (BVDV) in the Sebeta subcity area of Sheger city, Ethiopia. The study utilized a semi-structured questionnaire to gather information on herd management practices from dairy farm owners.

Background: A didelphic uterus represents a unique and infrequent congenital condition in which a woman possesses two distinct uteri, each with its own cervix. This anomaly arises due to partial or incomplete merging of the Müllerian ducts during the developmental stages in the womb. Accounting for uterine malformations, a didelphic uterus is a relatively rare condition, affecting approximately 0.
