-In the present study we measured serum glucose, leptin, total cholesterol and total protein concentrations in repeat breeder cows and compared them with fertile cows. For this aim, 20 repeat breeder cows and 20 fertile cows were used as material. Repeat breeder cows were found to have lower levels of leptin and glucose as compared with fertile ones. No significant differences in total cholesterol and total protein levels were observed between the two groups. No significant correlation of leptin with glucose, total cholesterol and total protein was observed in fertile and repeat breeder cows. Low concentrations of glucose and leptin can have some effects on reproductive problems as repeat breeder and help to understand potential mechanisms impairing fertility in repeat breeder cows.

The main objectives of our study were to measure the major adipokines adiponectin, leptin and resistin in goat milk, to assess their interrelationships and to assess their relationships with the plasma and serum concentrations of total protein, cholesterol, total lipids, plasma C-reactive protein (CRP), milk somatic cell count (SCC), milk total aerobic colony and lactobacillus count, and milk components in lactating Saanen goats. The study was performed on eighteen lactating Saanen goats. Milk and blood samples were collected on days 20, 35, 50, 65 and 80 of lactation postpartum. The milk and plasma adiponectin levels on days 50, 65 and 80 postpartum were significantly higher than those on day 20. The milk and plasma leptin levels were lower on day 20 than on days 35, 50, 65 and 80. The milk concentrations of these major adipokines were positively intercorrelated. The milk and plasma concentrations of these three adipokines were also positively correlated. The plasma CRP concentrations correlated positively with milk leptin and resistin concentrations and inversely with milk adiponectin concentration. Milk adiponectin concentration was inversely related with its SCC. These data confirm that adiponectin, leptin and resistin are present in goat milk. The milk concentrations of these three adipokines were interrelated and interacted with the general inflammatory marker, CRP. The inverse relationship between milk adiponectin concentrations and its SCC suggests that variations in milk adiponectin might be involved in the udder health of lactating goats, but clinical trials are needed to support this hypothesis.

Objectives The present study investigates the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the vaginal swabs of female patients diagnosed with coronavirus disease 2019 (COVID-19) based on a positive real-time reverse transcription polymerase chain reaction (RT-PCR) test on a combined throat and nasopharyngeal swab. Methods This study included 48 female patients hospitalized in two tertiary hospitals diagnosed with COVID-19 based on a positive RT-PCR test of the combined throat and nasopharyngeal swab samples, along with clinical and radiological findings. The IBM SPSS software package was used for the statistical analysis of the study data. Results SARS-CoV-2 positivity was detected in only one patient (2.08 %) in the present study from RT-PCR tests of vaginal swab samples. This patient was a 64-year-old, postmenopausal woman who tested positive for SARS-CoV-2 in a RT-PCR test of a vaginal swab sample six days after having tested positive in an RT-PCR test of a combined throat and nasopharyngeal swab. The patient’s partner also tested positive for SARS-CoV-2 in an RT-PCR of a combined throat and nasopharyngeal swab. Conclusions The present study is the first to report the presence of SARS-CoV-2 in vaginal secretions in Türkiye. The authors believe there is a need for studies investigating the presence of SARS-CoV-2 in the semen samples of the male partners of female patients to establish whether the presence of SARS-CoV-2 in vaginal secretions can play a role in the transmission of the virus.
