Polymorphism Identification in the Coding Sequences (ORFs) of the Porcine Pregnancy-Associated Glycoprotein 2-like Gene Subfamily in Pigs.

Genes (Basel)

August 2024

Department of Animal Anatomy and Physiology, Faculty of Biology and Biotechnology, University of Warmia and Mazury in Olsztyn, Oczapowskiego Str. 1A, 10-719 Olsztyn, Poland.

Pregnancy-associated glycoproteins (PAGs) are a polygenic family with many scattered genes and pseudogenes resulting from the duplication or fusion of a pseudogene with expression beginning in the trophoblast during the peri-implantation period and continuing in the trophectoderm. In this study, single-nucleotide polymorphism (SNP) and insertion/deletion (InDels) in the open reading frame (nine exons) of crossbreed pigs are reported for the first time. Novel SNPs/InDels were researched using genomic DNA templates isolated from the leukocytes of crossbreed pigs (N = 25), which were amplified, gel-out-purified, and sequenced.

Background: Safety and feasibility of transcatheter aortic valve replacement (TAVR) without balloon aortic valvuloplasty (BAV) using the SAPIEN 3 balloon-expandable device has been previously demonstrated. The impact on long-term valve hemodynamic performances and outcomes remains however unknown. We evaluate long-term clinical and hemodynamic results according to the implant strategy (direct TAVR vs BAV pre-TAVR) in patients included in the DIRECTAVI randomized trial (NCT02729519).

Background/objectives: The association between dietary acid load (DAL) and chronic kidney disease (CKD) progression remains controversial. Also, there is a gap in the literature on the association between DAL and mortality. In this study, we evaluated the association between NEAP (net endogenous acid production) and PRAL (potential renal acid load) and the risk of events of all-cause mortality and kidney replacement therapy (KRT) in people with CKD.

Background: The evaluation of health status by cardiopulmonary exercise test (CPET) has shown increasing interest in the paediatric population. Our group recently established reference Z-score values for paediatric cycle ergometer VO, applicable to normal and extreme weights, from a cohort of 1141 healthy children. There are currently no validated reference values for the other CPET parameters in the paediatric population.

Aims: Overweight and obesity in children with congenital heart disease (CHD) represent an alarming cardiovascular risk. Promotion of physical activity and cardiac rehabilitation in this population requires assessing the level of aerobic fitness (VO2max) by a cardiopulmonary exercise test (CPET). Nevertheless, the interpretation of CPET in overweight/obese children with CHD remains challenging as VO2max is affected by both the cardiac condition and the body mass index (BMI).

Adaptation and Validation of a French Version of the Vaccination Attitudes Examination (VAX) Scale.

Vaccines (Basel)

May 2023

Faculty of Psychology, Univ Paul Valéry Montpellier 3, Univ. Montpellier, Laboratory EPSYLON EA 4556, 34090 Montpellier, France.

Over the past decades, vaccination has proven to be largely beneficial to global health. Despite vaccine efficacy, the French population has been recently affected by more anti-vaccination attitudes and vaccine refusal, and it is therefore necessary to validate tools to study this health issue. The Vaccination Attitudes Examination scale (VAX) is a 12-item questionnaire targeting adults that assesses general attitudes towards vaccination.

Fondation Fondamental, Créteil, France; Centre Hospitalier de Versailles, Service Hospitalo-Universitaire de Psychiatrie d'Adultes et d'Addictologie, Le Chesnay, France; Université Paris-Saclay, Université Versailles Saint-Quentin-En-Yvelines, DisAP-DevPsy-CESP, INSERM UMR1018, 94807 Villejuif, France.

Background: Social metacognition is still poorly understood in schizophrenia, particularly its neuropsychological basis and its impact on insight and medication adherence. We therefore quantified social metacognition as the agreement between objective and subjective mentalization and assessed its correlates in a sample of individuals with schizophrenia spectrum disorders.

Methods: Participants consisted of 143 patients with schizophrenia or schizoaffective disorders who underwent a metacognitive version of a mentalization task, an extensive neuropsychological battery, and a clinical evaluation to assess their insight into illness and medication adherence.

Sorbonne Université, Hôpital de la Pitié Salpêtrière, iCRIN (Infrastructure for Clinical Research In Neurosciences), Brain Institute (ICM), INSERM, CNRS, Paris, France.

High stake clinical choices in psychiatry can be impacted by external irrelevant factors. A strong understanding of the cognitive and behavioural mechanisms involved in clinical reasoning and decision-making is fundamental in improving healthcare quality. Indeed, the decision in clinical practice can be influenced by errors or approximations which can affect the diagnosis and, by extension, the prognosis: human factors are responsible for a significant proportion of medical errors, often of cognitive origin.
