Paradigm Shift In Obesity Treatment: An Extensive Review Of Current Pipeline Agents, Ecesu Çeti̇n, Brian Pedersen, Mehmet Furkan Burak

Turkish Journal of Medical Sciences

Obesity is a multifaceted disease that poses a significant public health challenge. Recent discoveries in understanding the biological pathways that regulate satiety and metabolism have led to a shift in the treatment paradigm for obesity. Thus, the gap between pharmacological and surgical interventions has diminished. The latest approved anti-obesity medications are achieving weight loss comparable to surgery. These GLP-1 analog-based therapies not only cause substantial weight loss but also improve obesity-associated comorbidities. However, there are still unmet needs in obesity care, and treatment options with alternative pathways are necessary. Whether achieved through lifestyle changes or medication, weight loss often leads …

Thoracic Disc Herniations: Diagnosis, Surgical Techniques, And Complication Insights, Mehmet Deni̇zhan Yurtluk, Aydin Si̇nan Apaydin, Hakan Kina, Khoi Than

Turkish Journal of Medical Sciences

Abstract: Thoracic disc herniations (TDHs) are rare conditions, comprising 0.1% to 5% of all reported herniation cases, and affecting up to 1 in 1,000,000 individuals. The mid to lower thoracic spine, particularly between the T11 and T12 vertebrae, is most frequently affected and often associated with trauma. Conditions like Scheuermann’s disease can predispose patients to TDHs. This study explores the clinical manifestations, diagnostic methods, surgical techniques, and complications associated with TDHs. Diagnosis relies on magnetic resonance imaging and computed tomography myelography to identify the level and nature of the herniation. Various surgical approaches, including posterolateral, lateral, and anterior, have been …

Synthetic Osteobiologics In Spine Surgery: A Review, Aydin Si̇nan Apaydin, Eli Johnson, Prince Antwi, Brett Rocos, Michael M. Haglund, Christopher Shaffrey, Peter Passias, Muhammad Adb-El-Barr, Khoi Than

Turkish Journal of Medical Sciences

Background/aimOsteobiologics are increasingly used in orthopedics and spine surgery to facilitate bone healing and prevent non-union. Synthetic osteobiologics are artificial materials crafted in laboratories that aim to replicate the natural composition and functionality of bone. Notable examples, such as calcium phosphate and calcium sulfate, are engineered to mirror the mineral aspect of bone. They mimic human bone functionality, exhibiting osteoconductive, osteoinductive, and osteogenic properties. These characteristics promote cell attachment, migration, recruitment, and differentiation. Consequently, synthetic osteobiologics (osteoconductive grafts) have been introduced in bone fracture repair. The main strength of synthetic osteobiologics in spine surgery lies in improving fusion rates and …

New Index For Distinguishing Between Critical Illness Myopathy And Neuromyopathy: Cmap Amplitude/Duration Index, Handan Uzunçakmak Uyanik, Fatma Gökçem Yildiz, Çağri Mesut Temuçi̇n

Turkish Journal of Medical Sciences

Background/Aim: Critical illness-associated weakness (CIAW) is a common neuromuscular syndrome that may manifest as critical illness myopathy (CIM), critical illness polyneuropathy (CIP), or an overlap syndrome known as critical illness polyneuromyopathy (CIPM). Distinguishing between these subtypes can be challenging due to technical issues, patient-related factors such as insufficient cooperation with needle electromyography (EMG) and edema, and the need for sophisticated, time-consuming electrophysiological methods and invasive procedures such as biopsy. This study aims to contribute to the electrophysiological distinction between CIM and CIPM. Materials and methods: A new index was calculated based on distal compound muscle action potential (CMAP) amplitude and …

The Use Of Antiepileptic Drugs And Their Effects In Pregnancy, Pinar Öztürk, Ali̇ Turhan Çağlar

Turkish Journal of Medical Sciences

Background/Aim: Epilepsy is one of the most common chronic neurological diseases. Epilepsy can affect the entire life, including childbearing age. It is estimated that epileptic women give three to five births per thousand births. Although the use of antiepileptic drugs (AEDs) during pregnancy has been associated with major congenital malformations in the fetus, many patients cannot discontinue the drugs before pregnancy due to the risk of seizures that may harm the mother as well as the children. In this study, our aim is to examine the follow-up findings of pregnant women who are epileptic and use AEDs during pregnancy and …
