Spinal anesthesia (SA) is the most preferred method of anesthesia in cesarean deliveries because it eliminates the potential risks associated with airway management in pregnant women. Spinal anesthesia poses a risk of hypotension with an incidence of approximately 70%, resulting from decreased vascular tone due to sympathetic block. Hypotension can cause dizziness in the mother, nausea and vomiting, and acidosis in the fetus. Therefore, the prevention and treatment of postspinal hypotension has been an important area of research in obstetric anesthesia. The Perfusion Index (PI) is the ratio of pulsatile blood flow (arterial chamber) to non-pulsatile static blood flow (venous and capillaries) in a patient's peripheral tissue, such as the fingertip, toe, or earlobe. This can be obtained from a pulse oximeter. This is non-invasive and continuous monitoring. The pulse variability index (PVI) represents changes in PI that occur during one or more complete respiratory cycles. PVI is found by calculating over PI changes. Allows evaluation of intravascular volume; and a higher PVI is associated with greater responsiveness to fluid volumes. In our work; We will simultaneously observe PI and PVI changes in the lower and upper extremities in the study group patients. When we look at the previous studies; we see that the parameters (PI and PVI) that we will look at are evaluated with different combinations in our study group patients. When we look at these studies again; We saw that contradictory results were obtained for the same parameters. In our study, patients will be verbally informed in detail about the study in the preoperative period and their consent will be obtained. While the patients are taken to the operating room and monitored, the saturation probe will be connected to the 2nd finger of the upper and lower extremities of the patients, and the PI and PVI values in both extremities will be measured simultaneously. PI and PVI values and vital values (SAB, MAP, HR, SPO2) in both extremities before spinal anesthesia; intraoperative SAP, MAP, HR, SPO2, ephedrine requirement, atropine requirement and PI and PVI values in both extremities will be recorded. As a result; In our study, we aimed to observe simultaneous changes in PI and PVI in the lower and upper extremities in pregnant patients who will undergo cesarean section under spinal anesthesia, which is our study group.

Successful outcomes in CML require both prolonged adherence to oral TKI therapy by patients and careful monitoring of treatment responses by their physicians. Patient Reported Outcomes(PRO) assessment is important to facilitate decisions in the current treatment landscape of CML.

Detection and determination of platelets in bronchoalveolar lavage fluid and blood in ARDS and non-ARDS-patients. Correlation with phenotype and inflammation parameters in blood and outcome parameters.

TERABio Ltd. has developed a rapid screening tool intended to determine if a tested individual is COVID-19-free (Negative to COVID-19).

Skin melanoma is a common form of skin cancer. Its diagnosis is usually clinically suspected and then affirmed by histopathological examination. In some cases, the histopathological analysis of these lesions is equivocal, and the malignant or benign nature of the proliferation is difficult to determine with certainty. In these cases, the use of expensive ancillary tests, which are hardly accessible and take a long time to set up (FISH - CGH-array), is usually required. Anti-PRAME immunostaining, an inexpensive and readily available technic, has recently been described as highly sensitive and specific for diagnosing malignant melanocytic proliferations. Knowledge on its utility for evaluating ambiguous melanocytic neoplasms remains limited. Our study aims to improve the current body of knowledge on the utility of PRAME immunohistochemistry for evaluating challenging samples of melanocytic proliferation. The secondary objective is to determine the PRAME immunoreactivity profile for each histological subtype of melanocytic proliferations (spitzoid tumors, cellular blue nevi, dysplastic nevi ...)

Hypertonic saline (HS) is one of the most widely used scolocidal agents in the treatment of hydatid cysts. Hypernatremia is one of the complications associated with the use of HS. It can cause hypernatremia, acid-base disorder, impaired lung, renal, cardiac and neurological functions and even death. Therefore, caution should be exercised in the use of HS, and open technique should be preferred in surgery.

The adequacy of fluid resuscitation will be monitored in burn patients using microcirculation. Microcirculation camera will be placed on the base of the tongue and at different four quadrants. • Microcirculation parameters at baseline and after 8h , 16h and 24h of fluid resuscitation will be recorded. Fluid resuscitation with lactated ringer according to Parkland formula (4 ml/kg/%TBSA) 50% given during the first 8 hours, with the remainder given during the following 16 hours, will be initiated to maintain a urinary output of 0.5ml/kg/hr.Norepinephrine infusion will be started in case of circulatory failure at a rate of 0.02mic/kg/min to maintain MAP of 65-70mmHg.

The study to be performed aims to design and develope an automated Intelligent Decision Support System for fetal echocardiography that can significantly assist the obstetric physician in the improvement of detection of fetal congenital heart disease compared to the common standard of care.

Despite the natural progression of Cockayne's syndrome, affected patients also present with variable neurological and gastrointestinal damage (gastroesophageal reflux, recurrent vomiting, swallowing disorders, etc.) with varying repercussions on their growth. Acute intercurrent events such as seizures, constipation, infections can also interact with their metabolism, food intake and influence their growth. The nutritional deficit potentially involved in this growth retardation can be responsible for many manifestations such as anemia, bone fractures, fatigue, coagulation disorders responsible in total for the reduction in quality and life expectancy. Faced with growth retardation in patients with Cockayne syndrome, medical management is difficult to establish. Is this delay part of the natural course of the pathology?

The purpose of this study is to develop the adult tic disorders registry in order to characterize the relationship between tic severity and tic-related impairment in women compared to men with tic disorders.
