Effectiveness of Psychological Counseling Intervention in High-Risk Pregnancies in Italy.

Background: The longitudinal study examines the effectiveness of a psychological support treatment for high-risk pregnancies using a between-groups design. It assesses the treatment's impact on depression and fear of COVID-19 at three time points, and on prenatal attachment between the 20th and 24th weeks of gestation (T0), postnatal attachment 15-20 days after birth (T1), and three months after birth (T2). Additionally, the study evaluates the treatment's effectiveness on PTSD related to childbirth and parental distress at T1 and T2.

Expression of Taste Receptor 2 Subtypes in Human Testis and Sperm.

Taste receptors (TASRs) are expressed not only in the oral cavity but also throughout the body, thus suggesting that they may play different roles in organ systems beyond the tongue. Recent studies showed the expression of several TASRs in mammalian testis and sperm, indicating an involvement of these receptors in male gametogenesis and fertility. This notion is supported by an impaired reproductive phenotype of mouse carrying targeted deletion of taste receptor genes, as well as by a significant correlation between human semen parameters and specific polymorphisms of taste receptor genes.

Taste receptor polymorphisms and male infertility.

Study Question: Are polymorphisms of taste receptor genes associated with male infertility?

Summary Answer: This study has showed the associations between three single nucleotide polymorphisms (SNPs) in taste receptors genes (TASR) and male infertility.

What Is Known Already: Recent studies showed the expression of taste receptors in the testis and in spermatozoa, suggesting their possible role in infertility. The vast genetic variability in taste genes results in a large degree of diversity in various human phenotypes.

Impaired spermatogenesis in the twitcher mouse: A morphological evaluation from the seminiferous tubules to epididymal transit.

Unlabelled: Spermatogenesis is a complex process of proliferation and differentiation during male germ cell development whereby undifferentiated spermatogonial germ cells evolve into maturing spermatozoa. In this developmental process the interactions between different cell types are finely regulated, hence any disruption in these relationships leads to male infertility. The twitcher mouse, the murine model of Krabbe disease, is characterized by deficiency of galactosylceramidase, an enzyme also involved in the metabolism of the galactosyl-alkyl-acyl-glycerol, the precursor of sulfogalactosyl-alkyl-acyl-glycerol, the most abundant glycolipid in spermatozoa.

Single nucleotide polymorphisms of USP26 in azoospermic men.

Some studies have focused on the association between male infertility and single nucleotide polymorphisms (SNPs) in the ubiquitin-specific protease 26 (USP26) gene, but the results are controversial. In this case-control study including both normozoospermic men and patients with nonobstructive azoospermia, we analyzed both the entire coding region and 5' and 3' untranslated regions of USP26 in order to identify genetic variants in this gene to investigate the role of USP26 on spermatogenesis. We reported variations in the USP26 gene sequence in 82% of azoospermic and in 50% normospermic men.
