 Isotretinoin, one of the most frequently used drugs in routine dermatological practice, has been raised for teratogenicity with a black box warning. The aim of the current study was to evaluate the effect of low-dose isotretinoin on ovarian reserve in women with moderate to severe acne. A 6-month prospective controlled cohort study of 60 female acne patients and 66 controls receiving low-dose isotretinoin. Effects on ovarian reserve were evaluated by anti-Müllerian hormone, ovarian volume, and antral follicle count. As a result, there was no significant difference in serum anti-Mullerian hormone levels between isotretinoin-treated and control patients. In addition, there was no significant change in anti-Müllerian hormone levels before and after treatment in treated patients. Both ovarian volume and antral follicle number did not change significantly before and after treatment

 In this noncross-sectional study, dietary content and intake were assessed using a validated food frequency questionnaire in 203 overweight/obese adolescents. We measured iron reducing antioxidant capacity (FRAP), which indicates the total antioxidant capacity of the diet, anthropometric parameters and blood pressure status, and insulin, glucose, and lipid profiles from fasting blood samples. Two different methods [modified International Diabetes Federation (IDF) criteria and insulin resistance (HOMA)] were used to classify participants as metabolically healthy obese (MHO) or metabolically unhealthy obese (MUO). IDF criteria associated with] were applied. As a result, 79 (38.9%) were defined as MUO by the IDF criteria and 67 (33.0%) by the IDF/HOMA definition. On the IDF criteria, the highest FRAP tertile was associated with being less likely to be MUO in the maximally adjusted model compared to the lowest tertile. However, the IDF/HOMA-IR criteria showed no significant relationsh...
