An investigation of the effects of chronic zonisamide, sultiam, lacosamide, clobazam, and rufinamide anti-seizure medications on foliculogenesis in ovarian tissue in prepubertal non-epileptic rats.

We aimed to determine the morphological and histological effects of zonisamide, sultiam, lacosamide, clobazam, and rufinamide on ovarian folliculogenesis in rats. Sixty female Wistar rats were divided into six experimental groups as control, zonisamide, sultiam, lacosamide, clobazam, and rufinamide groups; control solution and drugs were administered by gavage for 90 days. The number of healthy follicles in the control group was significantly higher than in the anti-medication groups (p < 0.001), and the number of corpus luteum was significantly lower (p < 0.001). There was a significant difference in the number of TUNEL positive apoptotic follicles between the control and drug groups (p < 0.001). With EGF, IGF-1, and GDF-9 staining, a very strong immunoreaction was observed in the ovarian multilaminar primary follicle granulosa cells and oocytes in the control group compared to the drug group (p < 0.001). Long-term anti-seizure medication with zonisamide, sultiam, lacosamide, clobazam, and rufinamide from prepubertal to adulthood causes apoptosis and disruption of folliculogenesis in the ovarian follicles of nonepileptic rats.

An Investigation of Changing Attitudes and Behaviors and Problematic Internet Use in Children Aged 8 to 17 Years During the COVID-19 Pandemic.

PURPOSE: To examine the effects of the COVID-19 pandemic on the lifestyle, habits, and behavioral differences in children, and their changing internet use habits. METHODS: The research was planned as a cross-sectional study involving 4892 children aged 8 to 17 years attending schools in the city center of Trabzon, Turkey. Children's daily living activities, social habits, mood and temperament changes, and internet use were investigated before and during the pandemic. In terms of problematic internet use, internet addiction rates were evaluated using the validated Turkish-language version of the Parent-Child Internet Addiction Scale (PCIAT-20). RESULTS: The children's mean age was 13 ± 2.45 years, and 17.1% (n = 837) exhibited problematic internet use features on the PCIAT-20. Problematic internet use was higher in boys and in children older than 13 years. The presence of COVID-19 infection among members of the household, quarantine measures, attending private schools, the mother's occupation, the time spent by the mother and father on their mobile phones, and high parental education levels were associated with a high level of internet addiction. Families also described significant changes in their children's temperament and character compared with the pre-pandemic period. CONCLUSION: The prevalence of problematic internet use increased during the COVID-19 pandemic compared with previous studies from Turkey. Children were also more introverted, irritable, and pessimistic during the pandemic.

The association of lactating mothers' urinary and breast milk iodine levels with iodine nutrition status and thyroid hormone levels of newborns.

OBJECTIVE: To explore the iodine status of lactating mother-newborn pairs, and whether neonatal serum thyroid-stimulating hormone (TSH) can be used for estimation of iodine status of the population. MATERIALS AND METHODS: A total of 334 mothers and their healthy neonates were included. Urine, serum, and breast milk samples were obtained at 4th and 6th days of delivery. Urinary iodine concentration (UIC) was measured in urine samples of mothers and their neonates, as well as breast milk iodine concentration (BMIC) and serum thyroid hormone levels of neonates, were measured from the samples taken between the 4th and 6th days after birth. RESULTS: Median age of the mothers was 27 years (23-30). The median UIC of mothers and their newborns were 125 µg/L and 142 µg/L, respectively. The median BMIC was 138,0 µg/L. There was a significant positive correlation between the BMIC and UIC of neonates (r=0.276, p<0.001). The prevalence of neonatal serum TSH >10 mIU/L, which is suggestive of mild iodine deficiency (i.e. 3.0-19.9%), was 19.0%. However, there were no participants with iodine deficiency in lactating mothers and neonates according to UIC. CONCLUSION: By previous reports, Aydin is iodine sufficient. Although 19% of the neonates had serum TSH levels >10 mU/L, which is suggestive of a mild iodine deficiency, iodine deficiency was observed in none of the neonates and their mothers. Therefore, it will be appropriate to investigate the role of neonatal TSH levels in a larger sample to assess the iodine status of the population.
