Serum Galectin 7 is Not Useful to Predict Abortion in the First Trimester.

OBJECTIVE: Galectins are animal lectins that bind to surface glycoproteins expressed at the fetal-maternal interface. The aim of this prospective case-control study was to investigate the possible relationship between levels of maternal serum galectin-7 and threatened abortion (TA) and to determine whether serum galectin-7 had any prognostic value. METHODS: This prospective study was conducted between August 2014 and February 2015. Included in the study were 31 consecutive pregnant women who were hospitalized for TA between 6 and 14 weeks of gestation and 33 healthy gestational age matched pregnant women without any symptoms of miscarriage. Serum galectin-7 levels were measured via ELISA. RESULTS: The mean serum galectin-7 levels of the two groups were not significantly different (31 TA patients: 2.84 ± 0.43 pg/mL, 33 controls: 2.785 ± 0.32 pg/mL, p = 0.543). Six pregnancies in the TA group resulted in abortion (19.4%). CONCLUSION: Serum galectin-7 was not useful for predicting prognosis in TA.

Long-term effect of systemic isotretinoin on female fertility.

BACKGROUND/OBJECTIVE: Acne vulgaris is one of the most common diseases of the youth. Systemic isotretinoin is the only drug which acts on all of the etiopathogenic mechanisms of acne. Isotretinoin has some well-known side effects. Besides these, there is a suspicion whether it affects fertility or not. Previously, we conducted a study about isotretinoin's effect on ovarian reserve which showed deteriorative reserve. In this study, we aimed to evaluate the long-term effects of systemic isotretinoin on female fertility. MATERIALS AND METHODS: Of the 82 female patients who were enrolled in the first study, 79 patients were included in this study. Twelve months after the end of systemic isotretinoin treatment, patients were reevaluated by using the same parameters which include anti-Mullerian hormone (AMH), ovarian volume (OV), antral follicle count (AFC), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, free testosterone and total testosterone. RESULTS: The changes in the mean AMH, OV and AFC were statistically significant between the sixth and eighteenth months (the end of systemic isotretinoin treatment and 12 months treatment free). The mean AMH, OV and AFC values at the beginning and at the 18th month were statistically similar. CONCLUSION: The deteriorative effects of systemic isotretinoin treatment on ovarian reserve, which can be accepted as an indicator of female fertility, diminish in time.

Vitamin D, calcium homeostasis and aging.

Osteoporosis is characterized by low bone mass and microarchitecture deterioration of bone tissue, leading to enhanced bone fragility and consequent increase in fracture risk. Evidence is accumulating for an important role of calcium deficiency as the process of aging is associated with disturbed calcium balance. Vitamin D is the principal factor that maintains calcium homeostasis. Increasing evidence indicates that the reason for disturbed calcium balance with age is inadequate vitamin D levels in the elderly. In this article, an overview of our current understanding of vitamin D, its metabolism, and mechanisms involved in vitamin D-mediated maintenance of calcium homeostasis is presented. In addition, mechanisms involved in age-related dysregulation of 1,25(OH)2D3 action, recommended daily doses of vitamin D and calcium, and the use of vitamin D analogs for the treatment of osteoporosis (which remains controversial) are reviewed. Elucidation of the molecular pathways of vitamin D action and modifications that occur with aging will be an active area of future research that has the potential to reveal new therapeutic strategies to maintain calcium balance.

Diagnostic Accuracy of a New Urinalysis System, DongJiu, for Diagnosis of Urinary Tract Infection.

OBJECTIVE: The microscopic and chemical analysis of urine is essential for the diagnosis of patients with urinary tract infections (UTI). Quantitative urine culture is the 'gold standard' method for the diagnosis of UTI, but it is labour-intensive and time consuming. The DongJiu 8602 is a new automated urinalysis system with dipstick and microscopy testing. The aim of this study was to evaluate the analytical and diagnostic performance of DongJiu 8602 in comparison to urine culture as the reference method. METHODS: This retrospective study included 3970 urine samples, with a preliminary diagnosis of UTI and for which both urine analysis and urine culture were requested. Cut-off values for bacteria and white blood cells (WBCs) were determined by comparing the results with urine cultures. The cut-off values by the receiver operating characteristic (ROC) curve technique, sensitivity, and specificity were calculated for microscopy and dipstick parameters (nitrite and leukocyte esterase). RESULTS: Among the 3970 urine specimens submitted for culture, 3275 cultures (82.5%) were negative, and 695 were (17.5%) positive. The best cut-off values obtained from ROC analysis were 13/µL for bacteriuria (sensitivity: 31.1%, specificity: 91.8%), and 31/µL for WBCs (sensitivity: 48.6%, specificity: 85.9 %). We observed no significant difference between the area under the curves (AUC) of microscopy and dipstick parameters (p>0.05). CONCLUSION: According to our data, performances of microscopic and dipstick parameters of DongJiu 8602 were not satisfactory. Although, analytical sensitivity was improved slightly with combined assessment of microscopic and dipstick results for the lack of UTI, it did not achieve expected levels.

The effect of isotretinoin on ovarian reserve based on hormonal parameters, ovarian volume, and antral follicle count in women with acne.

UNLABELLED: BACKGROUD/AIMS: Widely prescribed in routine practice, isotretinoin has an unknown impact on ovarian reserve. With a long history in acne treatment and numerous potential side effects, it is surprising that very few prospective studies have investigated its effect on ovarian reserve. Therefore, we aimed to evaluate the impact of oral isotretinoin on ovarian reserve based on hormonal parameters, anti-Müllerian hormone (AMH), ovarian volume (OV), and antral follicle count (AFC) in women of reproductive age with acne. METHODS: Our study group consisted of 82 women of reproductive age with acne who were treated with oral isotretinoin. The patients were evaluated for ovarian reserve prior to therapy and reevaluated 6 months after isotretinoin treatment with regard to hormonal parameters, AMH, OV, and AFC. RESULTS: Significant differences were found between the pre- and posttreatment period for AMH [2.20 ng/ml (25th-75th percentile 1.14-4.07) vs. 1.31 ng/ml (0.32-2.28)], total AFC [16 (14-18.25) vs. 12.5 (10-15)], and total OV [23 ml (18-29) vs. 15 ml (13-18); p < 0.001]. CONCLUSION: Our study is the first to analyze the levels of serum AMH, AFC, and OV together in patients treated with oral isotretinoin for acne. The results of our study demonstrated that oral isotretinoin had a significant negative effect on ovarian reserve.
