The Evaluation of Contralateral Breast Lesions in Breast Cancer Patients Using Reduction Mammoplasty

Purpose: This study evaluated the importance of routine pathological examination of contralateral breast specimens in breast cancer patients using reduction mammoplasty. Methods: The weight of breast tissue resected from the contralateral breast in 71 patients and the number of slices used for pathological evaluation were recorded. Breast lesions found in the contralateral breast and accompanying lesions with tumors were examined. Results: High risk proliferative lesions were reported in the contralateral breast of eight (11.2%) patients, and low-risk lesions were detected in 18 (25%). While the mean age of the patients with high-risk lesions was 45.6, it was 52.8 for the other patients (p = 0.036). Conclusion: Bilateral reduction mammoplasty may be beneficial to delineate some pathologies in contralateral breasts even in those patients with normal clinical and radiological findings. The incidental discovery of these pathologies is much more likely in young breast cancer patients

Triglyceride-glucose index levels in patients with congenital hypogonadotropic hypogonadism and the relationship with endothelial dysfunction and insulin resistance

Introduction: The risk of cardiometabolic diseases is increased in patients with hypogonadism. The triglyceride-glucose (TyG) index is a novel surrogate marker of insulin resistance and is associated with cardiovascular diseases. We investigated the TyG index levels and the relationship with endothelial dysfunction and insulin resistance in patients with congenital hypogonadotropic hypogonadism (CHH). Material and methods: A total of 98 patients with CHH (mean age 21.66 ± 1.99 years) and 98 healthy control subjects (mean age 21.69 ± 1.21 years) were enrolled. The demographic parameters, TyG index, asymmetric dimethylarginine (ADMA), high-sensitivity C-reactive protein (hs-CRP), and homeostatic model assessment of insulin resistance (HOMA-IR) levels were measured for all participants. Results: The patients had higher waist circumference (p < 0.001), triglycerides (p = 0.001), insulin (p = 0.003), HOMA-IR (p = 0.002), ADMA (p < 0.001), and TyG index (p < 0.001) levels and lower HDL-C (p = 0.044) and total testosterone (p < 0.001) levels compared to healthy control subjects. TyG index levels significantly correlated with the ADMA (r = 0.31, p = 0.003) and HOMA-IR (r = 0.32, p < 0.001) levels. TyG index was also determinant of HOMA-IR levels (ß = 0.20, p = 0.018). Conclusion: The results of the present study show that patients with CHH had increased TyG index levels. Also, the TyG index is independently associated with insulin resistance in patients with CHH. Long-term follow-up studies are warranted to find out the role of the TyG index in determining cardiometabolic risk in patients with hypogonadism.

Adiponectin in Women with Polycystic Ovary Syndrome

BACKGROUND: Though adiponectin has been associated with insulin resistance and cardiovascular risk factors, the relationship between adiponectin and polycystic ovary syndrome (PCOS) remains controversial. The aim of this study was to compare adiponectin level in women with PCOS and without PCOS, and to investigate the relationship between adiponectin level and metabolic variables including insulin resistance. METHODS: 60 women with PCOS were enrolled along with a control group of 80 healthy women, matched for age and body mass index (BMI). We measured hormonal and metabolic parameters, as well as the plasma adiponectin concentration of each participant. We estimated the insulin sensitivity according to the quantitative insulin sensitivity check index (QUICKI). RESULTS: The PCOS group displayed significantly lower level of adiponectin (P < 0.001) after adjustment for age, BMI, mean blood pressure, fasting glucose, fasting insulin, and several metabolic parameters. Adiponectin levels were positively correlated with QUICKI in the PCOS group (P < 0.001) and the control group (P = 0.03). Following step-wise multiple regression analysis, however, adiponectin level was positively correlated with QUICKI in the control group only (P = 0.03). In addition, adiponectin level was found to be independently associated with HDL-cholesterol level (P < 0.001) and BMI (P = 0.02) in the PCOS group and independently associated with HDL-cholesterol (P = 0.02) in the control group. CONCLUSION: We report decreased adiponectin level in PCOS patients in relation to controls independently of insulin resistance or other metabolic factors. And adiponectin is associated with both lipid metabolism and obesity, which, in turn, is related to insulin resistance in PCOS. Further studies are needed to clarify the mechanism of adiponectin in PCOS.ope

The serum vaspin levels are reduced in Japanese chronic hemodialysis patients

Background: Visceral adipose tissue-derived serine proteinase inhibitor (vaspin) is an adipokine identified in genetically obese rats that correlates with insulin resistance and obesity in humans. Recently, we found that 7% of the Japanese population with the minor allele sequence (A) of rs77060950 exhibit higher levels of serum vaspin. We therefore evaluated the serum vaspin levels in Japanese chronic hemodialysis patients. Methods: Healthy Japanese control volunteers (control; n = 95, 49.9 +/- 6.91 years) and Japanese patients undergoing hemodialysis therapy (HD; n = 138, 51.4 +/- 10.5 years) were enrolled in this study, and serum samples were subjected to the human vaspin RIA system. Results: The measurement of the serum vaspin levels demonstrated that a fraction of control subjects (n = 5) and HD patients (n = 11) exhibited much higher levels (> 10 ng/ml; Vaspin(High) group), while the rest of the population exhibited lower levels (< 3 ng/ml; Vaspin(Low) group). By comparing the patients in the Vaspin(Low) group, the serum vaspin levels were found to be significantly higher in the control subjects (0.87 +/- 0.24 ng/ml) than in the HD patients (0.32 +/- 0.15 ng/ml) (p < 0.0001). In the stepwise regression analyses, the serum creatinine and triglyceride levels were found to be independently and significantly associated with the vaspin concentrations in all subjects. Conclusions: The creatinine levels are negatively correlated with the serum vaspin levels and were significantly reduced in the Japanese HD patients in the Vaspin(Low) group

Molecular mechanisms of vaspin action: from adipose tissue to skin and bone, from blood vessels to the brain

Visceral adipose tissue derived serine protease inhibitor (vaspin) or SERPINA12 according to the serpin nomenclature was identified together with other genes and gene products that  were specifically expressed or overexpressed in the intra abdominal or visceral adipose tissue  (AT) of the Otsuka Long-Evans Tokushima fatty rat. These rats spontaneously develop visceral  obesity, insulin resistance, hyperinsulinemia and ‐glycemia, as well as hypertension and thus represent a well suited animal model of obesity and related metabolic disorders such as type  2 diabetes.  The follow-up study reporting the cloning, expression and functional characterization of  vaspin suggested the great and promising potential of this molecule to counteract obesity induced insulin resistance and inflammation and has since initiated over 300 publications, clinical and experimental, that have contributed to uncover the multifaceted functions and molecular mechanisms of vaspin action not only in the adipose, but in many different cells, tissues and organs. This review will give an update on mechanistic and structural aspects of vaspin with a focus on its serpin function, the physiology and regulation of vaspin expression, and will summarize the latest on vaspin function in various tissues such as the different adipose tissue depots as well as the vasculature, skin, bone and the brain

Some Characteristics of the Beyşehir Lake Basin

The Beyşehir Lake basin (BLB), which is the study area, is the second largest sub-basin within the Konya province closed basin in terms of surface area with an area of 7.308 m2. BLB is a provincial border among Konya, Isparta and Antalya at southern part of Turkey. The location is getting importance of the basin.Some basin characteristics such as slope, elevation classes, land use, aspect groups, land capability class, erosion status were determined by Geographic Information System (GIS). Results of the study showed that BLB has 32% of flat and 25% of low slope in the basin. They emphasized the basin could be considered as a flat area. The altitude of the BLB ranged from 947 m to 2985 m, while 33.8% of the field had below 1091 m. BLB showed continental climate characteristics. The average of annual total precipitation in the basin was varied between 450 and 500 mm. Eastern and southern aspects were dominant in the basin.The natural resource potential in the basin was estimated by digital map showed specific conditions according to the specific characteristics and the present conditions. They have been recorded and the necessary measures taken for present to prevent future changes. Therefore, it was important for principles of watershed management

Associations Between Adiponectin and Two Different Cancers: Breast and Colon

Objectives: Breast and colon cancer are neoplasms well known to be related to obesity. Adiponectin, a protein that increases in obesity, seems to be involved in the relationship but clinical data are limited. Methods: In this study, we therefore evaluated the serum adiponectin levels in 87 breast and 27 colon cancer patients and assessed the relation with BMI, menopausal status, receptor status and stage of disease. Results: Serum adiponectin levels were lower in cancer cases (8583 +/- 2095 ng/ml for breast cancer, 9513 +/- 2276 for colon cancer) than in controls (13905 +/- 3263). Conclusion: A low serum adiponectin level may be associated with both breast and colon cancer, and that this association is not statistically significant for either receptor or menopausal status in breast cancer groups

Total excision and V-Y plasty technique in the anal area condyloma acuminatum

Condyloma acuminatum is located in the perianal region, anal canal, vagina and the perineum. It is caused by human papillomavirus types 6 and 11. A 18 year-old man was admitted to the clinic because of a perianal mass. On examination of the patient&#x2032;s perianal area and inside the anal canal, a mass was found, which was nearly 8 x 8 cm in size. We could not obtain any information about venereal transmission. The mass was totally excised and the defect was reconstructed with a bilateral V-Y advancement flap. This technique has been used for sacrococcygeal, ischial and other defects but rarely used for condyloma acuminatum. We think that total excision and the use of the V-Y advancement flap technique is safe and has low morbidity in the treatment of condyloma acuminatum
