Due to increasing life expectancy, women spend a significant part of their lives in menopause. Women with a history of endometriosis are more likely to become menopausal at an early age due to bilateral oophorectomy or repeated ovarian surgery. In addition, some medical therapies used for endometriosis, such as gonadotropin releasing hormone agonists or progestins reduce bone mineral density.

Background: In recent years, it has been determined that SOT sensitivity is insufficient in patients who develop vestibular compensation and therefore the Head Shake Sensory Organization Test (HS-SOT) has been developed.

Research Question: How differs the balance performance of healthy adults that is tested with HS-SOT according to age and test planes? What is the test-retest reliability level of the HS-SOT in three planes?

Methods: Our prospective study, which has a methodological research design, included 80 participants divided into three groups by age range (Group 1: 20-39 years (n = 30); Group 2: 40-49 years (n = 30) and Group 3: 50-64 years (n = 20)). SOT and HSSOT ( yaw, pitch, roll) were performed to all participants.

Background: To estimate a possible association between the effects of daily meteorological variation and climatological changes (temperature, air pressure, humidity, sunniness level) on pregnant women with hyperemesis gravidarum (HG) according to symptoms grade and hospitalization state.

Methods: A retrospective study was conducted with 118 patients diagnosed and hospitalized with HG. HG patients were graded as mild, moderate, or severe according to the Pregnancy Unique Quantification of Emesis (PUQE-24) scale.

Background/aim: Although many headache patients report that the frequency and severity of attacks vary according to the season or weather in clinical practice, the relationship between the characteristics of the attacks and the weather is not very clear in episodic headaches. We aimed to compare the effects of weather variables (temperature, wind speed, wind direction, humidity, pressure, ultraviolet index, and sunshine duration) on episodic migraine (EM) and episodic tension-type headache (ETTH) attacks (incidence, duration, and severity).

Materials And Methods: Fifty patients with EM and fifty patients with ETTH diagnosed according to International Classification of Headache Disorders-II are included in the study.

The level of safety for cyclists at roundabouts may vary according to national differences not only in the design itself but also sociodemographic, cyclist and driver behaviour as well as environmental factors. This paper investigates the national influence on cyclist casualty severity at roundabouts by comparing the United Kingdom (using Northumbria as a representative sample) and Belgium. The data included speed limits, socio-demographic characteristics, environmental conditions and driver/cyclist behaviour-related contributory factors.

Objective: Several methods are used to control the pain after cesarean operations. Recently, the transverse abdominis plane block (TAP) has been proposed to compensate for the problems developed by preexisting methods. In the present study, we compared the analgesic efficacy of the TAP block after caesarean section in a prospective, randomized, double-blinded controlled trial.

Introduction: In general, priority junctions are converted into roundabouts to increase capacity and reduce vehicle accidents. However, previous research has indicated that roundabouts are dangerous for vulnerable users, especially cyclists.

Method: This paper investigates which design factors influence cyclist casualty severity at give way (non-signalized) roundabouts with mixed traffic, using the UK STATS19 National dataset of cyclist casualties.

Purpose: We aimed to investigate that change of IPI values after sedation of patients undergoing cataract surgery under sedation.

Methods: We included 50 patients (ASA I-III) undergoing cataract surgery under sedation by phacoemulsification method in this prospective observational study. IPI, SpO, ETCO, respiratory rate (RR), peripheral pulse rate (PR), hemodynamic data and BIS values and perioperative complications were recorded.

Objectives: Coronary vasospasm in heart transplant recipients occurs through various mechanisms. It has been linked to allograft rejection and coronary vasculopathy, which can result in mortality during follow-up. Here, we investigated the prevalence of coronary vasospasm among heart transplant recipients undergoing surveillance coronary angiography procedures.

Objectives: Endomyocardial biopsy sampling is used to check acute rejection after cardiac transplant. However, it may lead to tricuspid valve injury and cardiac perforation; therefore, less invasive tools may be useful. Right heart catheterization provides valuable information about cardiac hemodynamics.

Aim: The aim of this study was to investigate the possible maternal and fetal factors, which affect the Umbilical Coiling Index (UCI).

Methods: This prospective, observational, analytic study was conducted using the data of 380 women with term pregnancy and newborns who presented at a University Hospital. Hemoglobin (Hb), ferritin, iron, and the total iron binding capacity (TIBC) of the maternal blood were measured, and transferrin saturation was estimated based on the ratio between serum iron and TIBC.

Background: The aim of this study is to evaluate the relationship between sperm parameters and body mass index (BMI) in the male spouses with infertility complaints, who had reffered to our clinic.

Materials And Methods: The male spouses from 159 couples reffering to our clinic because of infertility, during a six-month period, were included in the study. In this prospective case control study, the included men were categorized as non-obese (BMIP<25 kg/m), overweight (BMI 25-29 kg/m) and obese (BMI ≥30 kg/m) according to their BMIs.

Purpose: The main purpose of this study is to evaluate the inflammatory response and oxidative stress together in the cases of recurrent pregnancy loss (RPL) and repeated implantation failure (RIF).

Methods: This is a cross-sectional study conducted to compare infertile patients who have RIF and patients with RPL histories in terms of CCL2, TAS, TOS, and OSI. To this end, two study groups were formed by primary-infertile women with RIF history and women with nulliparous RPL history who consulted a university hospital between 2014 and 2016, and a control group was formed by multiparous women who had no pregnancy loss.
