Relationship Of Abdominal Circumference And Trunk Length With Spinal Anesthesia Block Height In Geriatric Patients Undergoing Transurethral Resection Of Prostate, Muhammad Yahya, Aliya Ahmed, Iayla Fatima, Muhammad Nasir

Department of Anaesthesia

Introduction: Spinal anesthesia is commonly used for various surgical procedures. Prediction of spinal anesthesia block height is always a challenging task for anesthetists. Higher than desired levels of spinal anesthesia blocks are associated with serious side effects, while inadequate block height does not provide satisfactory surgical anesthesia. In this study, we observed the relationship between the ratio of trunk length (TL) and square of the abdominal circumference (AC²) and spinal anesthesia sensory block height in geriatric patients undergoing transurethral resection of the prostate (TURP).
Material & Methods: This is a cross-sectional study conducted at the Aga Khan University …

Nielsen

Section of General Surgery

Recent studies have shown that immune infiltrates in the tumor microenvironment play a role in response to therapy, with some suggesting that patients with immunogenic tumors may receive increased benefit from chemotherapies. We evaluated this hypothesis in early breast cancer by testing the interaction between immune biomarkers and chemotherapy using materials from DBCG77B, a phase III clinical trial where high-risk premenopausal women were randomized to receive chemotherapy or no chemotherapy. Tissue microarrays were evaluated for tumor-infiltrating lymphocytes (TILs) assessed morphologically on hematoxylin and eosin-stained slides, and by immunohistochemistry for CD8, FOXP3, LAG-3, PD-1 and PD-L1. Following REMARK reporting guidelines, data …

Modified Jaw Thrust I-Gel Insertion Technique In Adults: A Case Series, Dileep Kumar

Department of Anaesthesia

Background: The I-gel is a second-generation supraglottic airway device that is built with a noninflatable elliptical gel material cuff and has a wide semirigid stem. The I-gel supralaryngeal seal has shown promising efficacy for both spontaneous and controlled ventilation under general anesthesia. The recommended, standard I-gel insertion technique is relatively challenging due to its shape and cuff size. Usually, the I-gel becomes entrapped at the oral cavity and requires excessive force to negotiate across the oropharynx, resulting in insertion resistance, tongue obstruction, insertion failure, and intraoral trauma. This case series evaluated a modified jaw thrust I-gel insertion technique because it …

Medical Imaging Stewardship And Healthcare Savings: Utilization Of Age Adjusted D-Dimer To Rule Out Acute Pulmonary Embolism, Phillip Bloodworth, Casey Morris, Kenneth Cail, Brian L. Pando, Brian Helmly

HCA Healthcare Journal of Medicine

Introduction

Acute pulmonary embolism (PE) is a common diagnosis that can lead to death if left untreated. Computerized tomography pulmonary angiogram scan (CTPA) is the gold standard for diagnosis of PE. Utilization of CTPA is increasing in the emergency setting even when suspicion for PE is very low. While CTPA is helpful, radiation exposure, contrast reactions, and cost must be considered. D-dimer is a well-established, high sensitivity and low specificity laboratory test that can effectively rule out PE in low-risk patients when negative. The ADJUST-PE trial showed that there is a natural rise of D-dimer levels with age. This age …
