Gastric Emptying After Sleeve Gastrectomy
Sleeve gastrectomy (SG) increases gastrointestinal motility, which influences feelings of fullness and satiety. By understanding the differences in gastric emptying (GE) between patients with sufficient weight loss (Total weight loss [TWL] > 35%) and insufficient weight loss (TWL < 25%), better insight in the aetiology of weight loss after sleeve …
Imaging Features for the Risks for Recurrence After Stereotactic Radiosurgery in Brain Metastasis
This trial uses multi-parametric magnetic resonance imaging (MRI) to develop and validate imaging risk score to predict radiation necrosis in participants with brain metastasis treated with radiation therapy. Diagnostic procedures, such as multi-parametric magnetic resonance imaging (MRI), may improve the ability to diagnose radiation necrosis early and help establish treatment …
Safety, Efficacy, and Survival Outcomes of Neoadjuvant/Induction Immunotherapy in Surgical and Radiotherapeutic Management of Non-Small Cell Lung Cancer
This multicenter retrospective real-world study aims to evaluate the safety, efficacy and survival outcomes of neoadjuvant/induction immunotherapy in patients with non-small cell lung cancer (NSCLC). The study covers diverse treatment pathways, including surgery, definitive radiotherapy, and non-surgical strategies. It addresses gaps in existing trials by establishing a comprehensive cohort spanning …
Observational Registry to Assess the Durability of Effect of CXL in Patients With Corneal Ectasia After Refractive Surgery
The objectives of this post market registry are to evaluate the safety and durability of treatment effect up to 3 years following cross-linking performed with Photrexa Viscous (riboflavin 5'- phosphate in 20% dextran ophthalmic solution), Photrexa (riboflavin 5'- phosphate ophthalmic solution), and the KXL System in patients with corneal ectasia …
Effectiveness of Screening and Decolonization of S. Aureus to Prevent S. Aureus Surgical Site Infections in Surgery Outpatients
The purpose of the study is to determine the effectiveness, safety, and health-care utilization and costs of a preoperative Staphylococcus aureus (SA) screening and decolonization bundle, (5 days of nasal mupirocin ointment, chlorhexidine gluconate (CHG) body wash, and CHG mouth rinse), in eradicating SA carriage compared to other SA decolonization …
Infrared Thermography for Prediction of Successful Erector Spinae Plane Block in Unilateral Inguinal Hernia Surgery in Paediatric Patients
This study aims to evaluate the accuracy of temperature change (ΔT) measurements using infrared thermography to predict a successful erector spinae plane block in pediatric patients undergoing inguinal hernia repair under general anesthesia.
Comparing Train-of-Four Recovery in the Adductor Pollicis Versus the Adductor Digiti Minimi in Elective Surgery Patients
The train-of-four (TOF) ratio is a quantitative measure used in anesthesia to assess the degree of neuromuscular blockade induced by neuromuscular blocking agents during surgical procedures. Current American Society of Anesthesiologists guidelines recommend monitoring the TOF ratio to guide the administration and reversal of NMBAs, with a target ratio of …
Prevalence and Severity of Depression Among Cardiothoracic Surgery Healthcare Workers in Baghdad: A PHQ-9 Cross-Sectional Study
This observational study aims to estimate the prevalence and severity of depression in HCWs in cardiothoracic surgery departments in Baghdad City, Iraq, using a self-administered PHQ-9 questionnaire. The main questions it aims to answer are: What is the prevalence of depression among cardiothoracic surgery healthcare workers? How is the severity …
THE ROLE OF HEXAMIDINE DIISETHIONATE (ZAMIDINE®) 1MG/ML 0.6ML EYE DROPS IN THE PROPHYLAXIS OF SURGERY OFTALMIC
Data will be gathered from patients who report having any kind of recurrent conjunctivitis and who, in accordance with clinical practice, are scheduled to have intravitreal injections, glaucoma surgery, cataract surgery, vitrectomy, combined cataract and vitrectomy, or corneal transplantation. The data will be obtained using pseudonyms from the patients' medical …
