Background: Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in reproductive-aged women, which affects 5 to 20% of women in the reproductive age worldwide. This study aimed to compare the levels of SCF in serum and follicular fluid of PCOS patients with those of non-PCOS group and to investigate the relationship of SCF levels with ICSI success.Methods: This is an observational case control study that included the patients who underwent ICSI in the Infertility-IVF center at Ankara University Faculty of Medicine and in a private IVF center between March 2016 and February 2017. The study group consisted of 57 PCOS patients diagnosed according to the Rotterdam criteria and the control group consisted of 75 patients with normofollicular and regular menstrual cycles. Serum and follicular fluid samples were taken on day of oocyte retrieval. Serum and follicular fluid SCF levels were determined by ELISA using the SCF ELISA kit..Results: Serum and follicular fluid SCF levels in PCOS patients were found to be lower than in non-PCOS group. sSCF and ffSCF were statistically significantly higher who had clinical pregnancy than those who had no clinical pregnancy in the PCOS group.Conclusions: SCF levels are low in serum and follicular fluid in patients with PCOS and that the increase in SCF levels is associated with an increase in oocyte maturation and clinical pregnancy rates in PCOS.

Aim. To investigate the relationship of the ovarian reserve to the levels of adipokines and sex hormones in reproductive-aged women with abdominal obesity. Subjects and methods. A total of 157 women aged 18 to 45 years with a body mass index (BMI) of more than 30 kg/m2 were examined (a study group). A control group consisted of 93 women aged 18—45 years with a BMI of less than 25 kg/m2. Anthropometric and carbohydrate and lipid metabolic parameters and the levels of sex hormones, anti-Müllerian hormone, resistin, and adiponectin were investigated. Results. The mean age of the participants with a BMI of more than 30 kg/m2 was 33.1±6.1 years and that of those with a BMI of less than 25—30 kg/m2 was 32.8±6.2 years. No statistically significant differences were found in age, ethnicity, and marital status between the participants of both groups; however, there was a statistically significant difference in education levels — 76.3% of the women with a BMI of less than 25 kg/m2 (p

Cxcr4 Axis

Previous studies have demonstrated that CXCL12/CXCR4 axis is closely related to tumors such as malignant pleural mesothelioma (MPM). This research was conducted in order to detect whether CXCL12/CXCR4 inhibitors could restrain MPM and have a synergistic effect with chemotherapy, also to investigate the relationship of CXCL12/CXCR4 with other gene expressions in MPM. Forty mice were injected MPM cells and randomly divided into four groups: the PBS (control group), AMD3100 (CXCR4-CXCL12 antagonist), pemetrexed and AMD3100 plus pemetrexed. The mice were treated respectively for duration of 3 weeks. The size, bioluminescence and weight of tumors were measured. The differences between gene expressions in each group were analyzed. The tumor weights of each treatment group were lower than that of the control group (p<0.05). The bioluminescence of the tumor of the AMD3100 treatment group and the AMD3100 plus pemetrexed treatment group were lower than that of the control group (p<0.05), and AMD3100 was shown to have synergistic effects with pemetrexed (p<0.05). Among the 2.5 billion genes, several hundreds of genes expressed differently between groups. Results show that AMD3100 and pemetrexed can inhibit the growth of MPM in vivo, also that there is a better result if both are used together. Our findings suggest that CXCL12/CXCR4 axis affects a certain amount of gene expression in MPM.

AbstractLoss aversion is a behavioral phenomenon that describes a higher sensitivity to losses than to gains and influences decisions. Decision-making is altered in several psychopathologic states, such as in the two symptom dimensions of hypomania and negative symptoms. It has been argued that progress in our understanding of psychopathology requires a reorientation from the traditional, syndrome-based perspective to a more detailed study of individual constituent symptoms. In the present study, we made careful efforts to dissociate the relationship of loss aversion to negative symptoms, from its relationship with hypomanic symptoms. We selected a sample of 45 subjects from a healthy student population (n = 835) according to psychopathologic scales for hypomania and negative symptoms and stratified them into a control group (n = 15), a subclinical hypomania group (n = 15) and a negative symptoms group (n = 15). Participants completed a loss aversion task consisting of forced binary choices between a monetary gamble and a riskless choice with no gain or loss. We found, that these two symptom dimensions of hypomania and negative symptoms have a similar inverse relation to loss aversion as demonstrated by analysis of variance. Further research is warranted to describe the underlying psychological and neurobiological mechanisms at play. Given the partially opposing nature of hypomania and negative symptoms it further needs to be elucidated whether they are linked to loss aversion via dissociable mechanisms.

Background: Several mediators play an important role in implantation. One of these mediators is human chorionic gonadotropin (HCG). Objective: To evaluate the effects of HCG intrauterine injection on the day of oocyte retrieval on the result of assisted reproductive techniques (ART). Materials and Methods: In this randomized clinical trial study, 126 women who were referred to Afzalipour Infertility Center between December 2018 to December 2019 undergoing in vitro fertilization/intracytoplasmic sperm injection cycles were enrolled and assigned to two groups of: a case (n = 62) and a control group (n = 64). The protocols for both groups were the same; except that the case group was injected with the protocols for both groups were the same, except that the case group was injected with 1000 IU of HCG into uterine cavity following the oocyte puncture, while no medication was administered to the control group. The implantation rate, chemical pregnancy, clinical pregnancy, and abortion rates were compared between the two groups. Results: Positive chemical pregnancy was seen in 15 (27.3%) cases of the case group and 14 (25.5%) of the control group. No significant difference was seen in the chemical and clinical pregnancy rates between the groups. The abortion rate was higher in the control group but that was not significant. Conclusion: A 1000 IU of HCG intrauterine injection after oocyte retrieval does not improve implantation, chemical or clinical pregnancy rates in ART cycles. Further studies are needed to clearly understand the role of HCG intrauterine injection in the day of oocyte retrieval in ART outcomes. Key words: Oocyte retrieval, Chorionic gonadotropin, Pregnancy, Assisted reproductive techniques.

Abstract Context.—Forensic pathologists regularly investigate the deaths of individuals with a history of drug abuse. Autopsy, including toxicology testing, reveals no cause for death in a subset of this cohort. Objective.—To determine whether deaths with an undetermined cause and manner of death are associated with a history of drug abuse. Design.—Retrospective matched case-control study of 52 decedents whose cause of death remained undetermined following autopsy, matched 1:2 to a control group of living patients admitted for cholecystectomy according to age and date of death or procedure. Results.—Individuals whose cause of death was undetermined were 5.3 times (95% confidence interval, 1.9– 14.5) more likely to have a history of drug abuse than were patients with cholecystitis. Conclusions.—Decedents with a history of chronic drug abuse appear to be at an increased risk of dying by their chronic drug abuse, even in the absence of any anatomical or toxicologic finding at autopsy to account for death.

Abstract Study question Is men’s adherence to the Mediterranean diet (MD) associated with sperm parameters and couples’ outcomes of assisted reproductive technologies (ART)? Summary answer Higher men’s adherence to the MD was associated with an increased probability of clinical pregnancy and live birth among couples undergoing ART. What is known already There is growing literature supporting the hypothesis that some nutrients, foods, and dietary patterns may be related to sperm quality and fertility. However, no previous studies analyzed the relationship of men’s adherence to the Mediterranean diet with sperm parameters and ART outcomes in the same cohort. Study design, size, duration The Environmental and Reproductive Health (EARTH) Study is a prospective preconception cohort of couples seeking fertility treatment at the Massachusetts General Hospital Fertility Center (Boston, USA). This analysis includes 314 men and their female partner, who underwent 791 ART cycles (2007–2020). Diet intake was measured by a validated semi-quantitative food frequency questionnaire completed prior to ART. Men’s adherence to the MD was estimated using the Trichopoulou score. Participants/materials, setting, methods Primary outcomes included: conventional sperm parameters (volume, sperm count, concentration, motility, and morphology), and ART outcomes (implantation, clinical pregnancy, and live birth). We estimated the marginal means and 95% confidence interval (95%CI) for semen parameters and the probability of ART (95%CI) by employing generalized linear mixed models while adjusting for several potential confounders. Sensitivity analyses by changing the cut-off points of adherence to the MD were tested. Main results and the role of chance At baseline, men had a median (IQR) age of 35.6 (32.6, 38.8) years and a BMI of 26.7 (24.0, 29.4) kg/m2. Female partner age median (IQR) was 35.0 years (32.0, 38.0) and BMI 23.3 (21.3, 26.6) kg/m2. Couples were mostly white and had never smoked. Men’s adherence to the MD was not associated with seminal parameters in the multivariable-adjusted models but it was related to a higher probability of clinical pregnancy and live birth. The predicted marginal proportions and confidence intervals among men in the lowest compared with the highest quartile of adherence to the MD were 0.25 (0.14, 0.40), 0.55 (0.41, 0.68) for clinical pregnancy (P-trend=0.005), and 0.19 (0.10, 0.32), 0.42 (0.30, 0.55) for live birth (P-trend=0.014). Male partner MD dietary pattern scores were unrelated to the probability of implantation. Sensitivity analyses using tertiles and quintiles of men’s adherence to the MD showed similar associations. Limitations, reasons for caution Although we have adjusted our models by several potential confounding factors, residual confounding cannot be ruled out, and therefore our results should be interpreted with caution. The findings may not be generalizable to other populations or couples attempting conception without ART. Wider implications of the findings: According to our knowledge, this is the first study suggesting that adherence to MD could be suitable dietary guidance for men whose partners are undergoing infertility treatment.

Chronic Ambulatory Peritoneal Dialysis

To examine the relationship of the formation of biofilm (adherent bacterial microcolonies) to recurrent peritonitis in patients on continuous ambulatory peritoneal dialysis (CAPO) we examined the surfaces of 25 recovered Tenckhoff (T) catheters by scanning electron microscopy (SEM) and microbiological examination of scrapings. Twelve catheters had been removed after successful transplantation; the patients had not been dialyzed for three months and had no evidence of peritonitis during that period (control group), and only seven had experienced peritonitis (I or 2 episodes) before transplantation. All 13 patients in the study group had experienced repeated episodes of peritonitis (range 3–13, average, 5.6). We detected no significant differences between the control and study groups with respect to the percentage of catheter-surface covered by biofilm, or the proportion of catheter segments whose scrapings yielded positive bacterial cultures. It is concluded that large areas of the T catheters of CAPO patients are colonized by bacterial biofilms but only active dialysis predisposes to recurrent peritonitis.

Background Familial Mediterranean Fever and celiac disease are both related to auto-inflammation and/or auto-immunity and they share some common clinical features such as abdominal pain, diarrhea, bloating and flatulence. Objectives We aimed to determine the association of these two diseases, if present. Methods Totally 112 patients diagnosed with Familial Mediterranean Fever and 32 cases as healthy control were included in the study. All participants were examined for the evidence of celiac disease, with serum tissue transglutaminase IgA levels (tTG IgA). Results Totally 144 cases, 112 with Familial Mediterranean Fever and 32 healthy control cases were included in the study. tTG IgA positivity was determined in three cases with Familial Mediterranean Fever and in one case in control group. In that aspect there was no significant difference regarding the tTG IgA positivity between groups (P=0.81). Duodenum biopsy was performed to the tTG IgA positive cases and revealed Marsh Type 3b in two Familial Mediterranean Fever cases and Marsh Type 3c in the other one while the biopsy results were of the only tTG IgA positive case in control group was Marsh Type 3b. In HLA evaluation of the celiac cases; HLA DQ2 was present in two celiac cases of the Familial Mediterranean Fever group and in the only celiac case of the control group while HLA DQ8 was present in one celiac case of the Familial Mediterranean Fever group. Conclusions We did not determine an association of Familial Mediterranean Fever with celiac disease. Larger studies with subgroup analysis are warranted to determine the relationship of these two diseases.

AbstractBackground:The aim of this study was to determine the serum levels of kisspeptin and ghrelin (GAH), as well as the relationship of these two peptides with each other in premature thelarche (PT) and premature adrenarche (PA) cases and to investigate the possibility of using these peptides as markers in the differentiation of puberty disorders.Methods:A PT group aged 1–8 years (n = 40), a PA group aged 1–9 years (n = 23, female/male = 20/3) and control groups consistent with each of the previous groups in terms of age and gender were created for the study. Kisspeptin and ghrelin levels were measured with ELISA methods from blood samples drawn while fasting in the morning.Results:When the PT group was compared with the controls, the plasma kisspeptin levels of the cases were significantly higher than the control group (165.47 ± 15.45 pmol/L, 96.82 ± 12.33 pmol/L, p = 0.005, respectively). Kisspeptin levels in the PA group did not show a difference with the control group (121.36 ± 17.99 pmol/L, 95.52 ± 11.54 pmol/L, p = 0.249, respectively). No significant difference could be found when GAH levels in the PT and PA groups were compared with controls. No significant correlation was found between kisspeptin and GAH levels in the PT and PA groups.Conclusions:Our results indicate that kisspeptin plays an important role in the PT, but GAH is not associated with puberty disorders.
