The Effect of Prednisolone Treatment on Pregnancy Rates in Fertilization Patients with Positive Thyroid Autoantibodies.

Objective: This study aims to investigate the effect of prednisolone treatment on the pregnancy rates of fertilization (IVF) patients with positive thyroid autoantibodies.

Methods: This study was conducted in the IVF unit of Gazi University Faculty of Medicine. It included 158 patients who underwent intracytoplasmic sperm injection using the long-term protocol of a gonadotropin-releasing hormone (GnRH) agonist that was positive for thyroid autoantibodies.

A cross-sectional study in non-anaemic pregnant women in Turkey to assess necessity of iron supplementation.

Background: Iron deficiency is the most common cause of anaemia in pregnancy. Guidelines recommend different threshold values for iron supplementation.

Aims: To determine trimester-specific reference ranges for haematological values (haemoglobin, hematocrit and ferritin) in healthy pregnant women who have not used any iron supplementation during pregnancy to guide future iron treatment.

Oncological and functional outcomes of open versus laparoscopic partial nephrectomy in T1b tumors: A single-center analysis.

Purpose: This study aims to evaluate the oncological and functional results of open partial nephrectomy (OPN) and laparoscopic partial nephrectomy (LPN) at the T1b clinical stage, which constitutes 25% of renal cell carcinomas (RCC) at diagnosis.

Materials And Methods: The characteristics of 63 patients with stage T1b solitary tumor who underwent OPN (41) or LPN (22) were compared. The survival analysis was performed using the Kaplan-Meier method.

Inverse-square law between time and amplitude for crossing tipping thresholds.

A classical scenario for tipping is that a dynamical system experiences a slow parameter drift across a fold tipping point, caused by a run-away positive feedback loop. We study what happens if one turns around after one has crossed the threshold. We derive a simple criterion that relates how far the parameter exceeds the tipping threshold maximally and how long the parameter stays above the threshold to avoid tipping in an inverse-square law to observable properties of the dynamical system near the fold.

Primary Signet Ring Cell Carcinoma of the Prostate: A Rare Case Report.

Primary prostatic signet ring cell carcinoma is a rare form of cancer with a poor prognosis, which is generally treated with a traditional prostate adenocarcinoma therapy. This case report presents a 70-year-old diagnosed with primary prostatic signet ring cell carcinoma, treated with a combination of radiotherapy and hormone therapy and a 16 month survival without an evidence of the disease at follow up.
