  Screening-based low energy availability risk, disordered eating risk, and their co-occurrence among female volleyball players: a cross-sectional study

  André, Hülya; Sarışık, Derya Çetin; Özçelik, Arda

  Low energy availability (LEA) and disordered eating (DE) are important health concerns in female athletes, yet their occurrence and co-occurrence in team-sport contexts, particularly volleyball, remain underexplored. This cross-sectional online survey study examined the proportions of athletes classified as being at risk of LEA and DE overall and across competition levels, and assessed the co-occurrence between the two risk classifications in female volleyball players in Türkiye, using the Low Energy Availability in Females Questionnaire (LEAF-Q) and Eating Attitudes Test-26 (EAT-26). It also examined correlations between EAT-26 total score and LEAF-Q total and domain scores. A total of 213 athletes, recruited via non-probability convenience sampling, completed the LEAF-Q and EAT-26 to assess LEA risk and DE risk, respectively. In this sample, 33.3% of athletes were classified as being at risk of LEA, with no difference across competition levels (p = 0.825). A total of 17.4% were classified as being at risk of DE, with variation across competition levels and the highest proportion among Turkish Women’s Volleyball Second League athletes (p = 0.034). LEA risk and DE risk co-occurred in 10.3% of the sample, and DE risk was associated with higher odds of LEA risk (unadjusted OR = 3.80, 95% CI: 1.82–7.92). EAT-26 total score was positively correlated with LEAF-Q total and gastrointestinal function scores (p < 0.001) and injury history score (p = 0.004), but not menstrual function score (p = 0.133). These results suggest that LEA risk was commonly identified in this sample, DE risk was comparatively less common, and their co-occurrence was only partial, highlighting the value of screening for both risks rather than assuming one from the other.

  Examining the attitudes of sexually abused and non-abused individuals towards marriage in terms of ambivalent sexism

  Çelik, Eyüp; Dombak, Kübra; Kaya, Mehmet; Sahranç, Ümit; Makas, Samet; Koçak, Lokman; Takunyacı, Mithat; Bekir, Seyhan

  The research aims to examine the attitudes of individuals who are victims of abuse and those who are not towards marriage in terms of ambivalent sexism. The research study group consists of 718 individuals between the ages of 18–48. Research data were collected with the Inonu Marriage Attitude Scale and Ambivalent Sexism Inventory. As a result of the correlation analysis, it was concluded that the marriage attitude was positively and significantly correlated with hostile and protective sexism. However, since the relationship between hostile sexism and attitudes towards marriage is lower than that of protective sexism, hostile sexism was not included in the model as a control variable. In the covariance analysis, it is seen that protective sexism and sexual abuse predict the attitude towards marriage at a statistically significant level. In addition, when the effect of sexual abuse on the attitude towards marriage was examined by controlling the protective sexism variable, it was found that it was statistically significant without the effect of sexism. According to the findings, it was determined that individuals who were not victims of sexual abuse had higher attitudes towards marriage than those who were victims. Copyright:

  Spontaneous Mutation Reveals Influence of Exopolysaccharide on Lactobacillus johnsonii Surface Characteristics

  Horn, Nikki; Wegmann, Udo; Dertli, Enes; Mulholland, Francis; Collins, Samuel R. A.; Waldron, Keith W.; Bongaerts, Roy J.; Mayer, Melinda J.; Narbad, Arjan

  As a competitive exclusion agent, Lactobacillus johnsonii FI9785 has been shown to prevent the colonization of selected pathogenic bacteria from the chicken gastrointestinal tract. During growth of the bacterium a rare but consistent emergence of an altered phenotype was noted, generating smooth colonies in contrast to the wild type rough form. A smooth colony variant was isolated and two-dimensional gel analysis of both strains revealed a protein spot with different migration properties in the two phenotypes. The spot in both gels was identified as a putative tyrosine kinase (EpsC), associated with a predicted exopolysaccharide gene cluster. Sequencing of the epsC gene from the smooth mutant revealed a single substitution (G to A) in the coding strand, resulting in the amino acid change D88N in the corresponding gene product. A native plasmid of L. johnsonii was engineered to produce a novel vector for constitutive expression and this was used to demonstrate that expression of the wild type epsC gene in the smooth mutant produced a reversion to the rough colony phenotype. Both the mutant and epsC complemented strains had increased levels of exopolysaccharides compared to the wild type strain, indicating that the rough phenotype is not solely associated with the quantity of exopolysaccharide. Another gene in the cluster, epsE, that encoded a putative undecaprenyl-phosphate galactosephosphotransferase, was deleted in order to investigate its role in exopolysaccharide biosynthesis. The ΔepsE strain exhibited a large increase in cell aggregation and a reduction in exopolysaccharide content, while plasmid complementation of epsE restored the wild type phenotype. Flow cytometry showed that the wild type and derivative strains exhibited clear differences in their adhesive ability to HT29 monolayers in tissue culture, demonstrating an impact of EPS on surface properties and bacteria-host interactions.
