We demonstrated some adverse effects of Ramadan fasting on fetal development. In the Islamic religion, pregnant individuals have the privilege of not fasting; therefore, they should consider postponing fasting to the postpartum period, especially in the summer season. If they are willing to do so, an appropriate nutritional program should be recommended.
We aimed to evaluate the role of thyroid autoantibodies (TAA) on the outcomes of intracytoplasmic sperm injection-embryo transfer (ICSI-ET). A prospective case-control study was conducted in the in vitro fertilisation (IVF) centre of Suleymaniye Maternity Training and Research Hospital, Istanbul, Turkey between July 2013 and March 2014. A total of 49 (19.52%) TAA-positive and 202 TAA-negative patients were enrolled. Demographic characteristics and laboratory parameters were recorded. All patients underwent ICSI-ET. Thirty-one TAA-positive patients (32 cycles) and 121 TAA-negative patients (126 cycles) completed the study. Mean female age, body mass index (BMI), type of infertility, duration of infertility, antral follicle count (AFC), anti-Müllerian hormone (AMH), basal follicle stimulating hormone (bFSH), luteinising hormone (bLH), and oestradiol (bE2), prolactin and thyroid hormone profiles, male age and aetiology of infertility of both groups were similar (p > 0.05). There was no significant difference between groups in terms of duration and dose of gonadotropin (Gn) therapy, day of human chorionic Gn (hCG) administration, serum E2 and progesterone levels, number of collected oocytes, ratio of fertilisation, number of available embryos, positive pregnancy test, biochemical pregnancy, clinical pregnancy, ratio of miscarriage and ongoing pregnancy (p > 0.05). In conclusion, we failed to demonstrate a significant role of TAA on the outcomes of ICSI-ET in euthyroid patients. Further studies with larger numbers of participants are required to clarify these data.
Objective: This study was aimed to compare the clinical outcomes of ovulation induction (OI) by timed intercourse with letrozole (LTZ) and clomiphene citrate (CC). Methods: Three hundred and twenty-three patients with polycystic ovary syndrome (PCOS) who underwent OI with LTZ or CC between February 2017 and November 2018 were included in this retrospective study. The patients were divided into two groups as the CC group (n=148) and the LTZ group (n=175). Endometrial thickness, follicular development, ovulation, clinical pregnancy, abortion, and live birth rates of the groups were analyzed. Results: The mean endometrium thickness of the CC group was 7.1±1.7 mm, and the LTZ group was 8.6±1.8 mm (p<0.001). The ovulation rate per cycle was higher in the LTZ group (93.1%) in comparison with the CC group (83.8%) (p=0.013). Clinical pregnancy rates were 52% in the LTZ group, and 41.2% in the CC group (p=0.047). LTZ with 44% of live birth rate was superior to CC with a 33% live birth rate (p=0.029). Conclusions: LTZ is an effective OI agent in PCOS patients. LTZ is superior to CC in terms of pregnancy rates and live birth rates. As a result, we recommend that LTZ should be the first-line treatment agent in patients with PCOS. doi: https://doi.org/10.12669/pjms.36.7.3345 How to cite this:Sakar MN, Oglak SC.

There is growing evidence that diminished ovarian reserve (DOR) may be associated with cardiovascular disease (CVD). The aim of the study was to investigate whether there was any relationship between antimullerian hormone (AMH) and CVD risk markers in the study. Ninety women with DOR and 90 women with normal ovarian reserve (NOR) attending the infertility unit at XXXX, were enrolled in the study. CVD risk markers such as insulin resistance [defined by the homeostasis model assessment ratio (HOMA-IR)], C-reactive protein (CRP), low density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), and triglyceride (TG) were assessed. HOMA-IR, CRP, TG, LDL levels were higher and HDL and AMH were lower among patients with DOR compared with controls (p < 0.05, for all). There were positive associations between low AMH and HOMA-IR, CRP, TG, LDL levels and a negative correlation with HDL (p < 0.05, for all). However, multivariate logistic regression analysis showed that HOMA-IR, CRP, TG and HDL were independent variables that were associated with low AMH. There was a close relationship between low AMH and CVD risk markers in the study. Further studies with larger groups are needed to investigate the nature of this link in these patients.
induced by various treatments (Ludder and Heavner 1979, Severin 1995). Pure agonist opioids are known to cause bradycardia and a decrease in blood pressure (Wilson 1992). The marked decrease in Schirmer tear test values observed may also be due to the central effects of opioids on neural regulation of tear production; neural control is the primary factor regulating tear production (Dart 1994). It is known that in human beings, dogs and rabbits opioid agonists tend to cause central nervous depression (Hall and others 2001).Although there are no previous reports of the effects of pethidine and fentanyl on tear production, it has been demonstrated that a combination of medetomidine and buprenorphine caused a significant decrease in Schirmer tear test values, from 16·9 (1·08) to 1·7 (0·94) mm/minute, 10 minutes after treatment (Soontornvipart and others 2003). When opioids are combined with sedatives synergism seems to occur, the sedation and analgesia produced being greater than that capable of being achieved by either drug alone (Hall and others 2001). Compared with the results of the present study, higher decreases in tear test values following administration of medetomidine and buprenorphine may be attributable to more effective antinociception.The results of this study indicate that pethidine and fentanyl both cause a significant decrease in tear production. For this reason, these drugs should not be used for sedation or analgesia before the diagnosis of ocular diseases related to lacrimal secretion.
