Understanding the Impact of Environmental Variability on Anchovy Overwintering Migration in the Black Sea and its Implications for the Fishing Industry

Black Sea anchovy (Engraulis encrasicolus) undertake extensive overwintering migrations every fall from nursery grounds to warmer overwintering areas located on the south-eastern coast of the Black Sea. During migration and particularly upon arrival at the Anatolian coast, they support an important fishery and valuable source of income for the regional community. Black Sea anchovy have undergone significant stock fluctuations partly related to climatic conditions; for example, migrating anchovy schools arrived late or failed to arrive at the Anatolian coast when fall temperatures increased. It is therefore of importance to understand the conditions required for successful overwintering migration and explore different migration routes. This study invokes a Lagrangian modeling approach applied to satellite derived circulation and temperature data as a first attempt to model anchovy migration dynamics in the Black Sea. This modeling approach takes the influence of the physical environment into account, while the quality of overwintering grounds, adaptive, schooling, and homing behavior is neglected. The model is used to investigate the possible influence of interannual and seasonal variability of temperature and surface currents, as well as the influence of migration behavior on the success of anchovy overwintering migration for both the Black Sea and Azov Sea anchovy. The results of the present work show the possibility that overwintering anchovy fished along the Turkish Eastern Anatolian coast may not exclusively originate from the northwestern shelf, but mainly from the eastern Black Sea basin. Migration pathways are identified for both Black Sea and Azov Sea anchovy, which are of importance for the national fisheries efforts of riparian countries. The modeling results are in agreement with general patterns of anchovy migration given in the literature indicating that the physical environment may be a major factor in shaping general migration patterns. Simulation results are used to hypothesize about alternatives to previously determined migration routes and provide potential reasons that explain the inability of the Bulgarian anchovy fishery to recover. Results show that the intensity and timing of autumnal cooling, coupled with current strength, can be of significant importance in determining annual and seasonal variability of migration success. Considering the need for fisheries management to account for the variability in fishable overwintering anchovy stocks a modeling approach as developed in the current study may provide such a tool

The Role of Serum Caspase 3 Levels in Prediction of Endometriosis Severity

Background/Aims: To identify the role of serum caspase 3, Annexin A2 (ANXA2), and Soluble Fas Ligand (sFasL) levels in the prediction of endometriosis severity. Methods: The study was performed on 90 women who were candidates for laparoscopic surgery due to endometrioma or any other benign ovarian cysts detected by ultrasound examination, pelvic pain, or infertility. The control group comprised 29 patients. The second group comprised 29 patients with stage I-II endometriosis and the third group comprised 30 patients with stage III-IV endometriosis. Results: Significant differences were detected between the control and stage III-IV endometriosis groups and between stage I-II and stage III-IV endometriosis groups in terms of caspase-3 levels (both, p < 0.001), ANXA2 levels (p = 0.007 and p = 0.002), and sFasL levels (p = 0.022 and p = 0.044). After receiver operating characteristic analysis, the area under curve was 93% (95% CI 57-82) at 10.7 ng/mL cut-off level for caspase-3 with 90% sensitivity and 87% specificity. Conclusion: Serum caspase-3 level may be a reliable predictor of endometriosis severity. (c) 2018 S. Karger AG, Base

Is There an Appropriate Cutoff Age for Sampling the Endometrium in Premenopausal Bleeding?

Aim: To determine a cutoff age for endometrial evaluation in premenopausal abnormal uterine bleeding (AUB). Methods: Histopathology reports of endometrial sampling performed due to AUB in women aged 50 years or less were reviewed retrospectively. Histopathologica I findings were categorized into three groups as follows: group 1: hyperplasia without atypia + hyperplasia with atypia + malignancy, group 2: hyperplasia with atypia + malignancy, and group 3: malignancy. Results: Data from 2,516 patients were analyzed for this study. Overall, 13.5% of patients had endometrial hyperplasia without atypia, 1% of patients had hyperplasia with atypia and 0.6% of patients had malignant disease. Logistic regression revealed a significant difference in the odds ratios of group 1 in the age ranges of 40-45 and 45-50 years compared with <40 years (p = 0.001 and p = 0.01, respectively). There were no significant differences between the age groups for the odds ratio of group 2 and group 3. Conclusion:There is no cutoff age for sampling the endometrium in order to detect hyperplasia with atypia and cancer in premenopausal women with AUB. Therefore, the management of AUB should be tailored to each patient regardless of age, incorporating all risk factors for malignant disease. (C) 2013 S. Karger AG, Base

The prediction of para-aortic lymph node metastasis in endometrioid adenocarcinoma of endometrium

The aim of this study was to assess factors associated with para-aortic lymph node metastasis in endometrioid adenocarcinoma. The data of 157 patients with endometrioid adenocancer, who underwent staging surgery, was reviewed retrospectively. A total of 23 patients (14.6%) had pelvic and 19 patients (12.1%) had para-aortic lymph node metastasis; 21% (4/19) of the patients with para-aortic lymph node involvement did not have pelvic lymph node metastasis. Para-aortic lymph node involvement was significantly more common in the presence of LVSI and pelvic lymph node metastasis, and pelvic lymph node metastasis was the only independent risk factor for para-aortic lymph node involvement. The sensitivity and NPV of positive pelvic lymph node in the prediction of para-aortic lymph node metastasis were found to be 78.9% and 97%, respectively. The corresponding rates for obturator and/or external iliac lymph node were 63.1% and 95%, respectively. In conclusion, although pelvic lymph node metastasis is the only independent risk factor for para-aortic lymph node involvement, negative pelvic lymph node is not enough to omit para-aortic lymph node dissection. On the other hand, intraoperative frozen section examination of obturator and/or external iliac lymph node to omit para-aortic lymphadenectomy might be a good option for the patients who have high medical risks for surgery

High visceral adiposity index is associated with female orgasmic disorder in premenopausal women: a cross-sectional study

This study aimed to evaluate the association between the visceral adiposity index (VAI) and female sexual dysfunction (FSD). This cross-sectional study included 165 premenopausal, sexually active women admitted to the gynaecology outpatient clinic between January 2021 and April 2021. Female Sexual Function Index (FSFI) was used to assess the sexual function of the women. After measuring body mass index (BMI) and waist circumference (WC), biochemical serum analysis was performed. The VAI was calculated for all participants. The relationship between VAI and total FSFI and subdomain scores was investigated. Of the participants, FSD was detected in 65.5%. There was no relationship between the total FSFI scores and age, BMI, WC and VAI (p = .126, p = .675, p = .790, p = .220, respectively). Increased VAI levels were associated with dysfunction in orgasm (p = .008). Although VAI seems not to be directly related to FSD, it may predict the orgasmic disorder in women.Impact Statement What is already known on this subject? Obesity and female sexual dysfunction (FSD) are common health problems which adversely affect the biopsychosocial well-being. Although the relationship between FSD and obesity, body mass index (BMI) and waist circumference (WC) has been widely discussed in the literature to date, there is not enough evidence for the link between FSD and visceral adiposity index (VAI) which is a reliable indicator of visceral fat dysfunction. What do the results of this study add?The results of this study showed that none of the factors indicating obesity such as BMI, WC and VAI were correlated with the total FSFI scores. However, a significant positive correlation was found between the VAI and female orgasmic disorder (FOD). What are the implications of these findings for clinical practice and/or further research? The VAI may be a useful tool for detecting FOD patients. Diagnosis and treatment of orgasmic disorder would significantly improve the patient’s quality of life and general well-being. Further large-scale and high-evidence studies are needed to clarify the impact of obesity on FSD and the relationship between VAI and FOD
