Advanced brain imaging of neonatal macrostructure and microstructure, which has prognosticating importance, is more frequently being incorporated into multi-center trials of neonatal neuroprotection. Multicenter neuroimaging studies, designed to overcome small sample sized clinical cohorts, are essential but lead to increased technical variability. Few harmonization techniques have been developed for neonatal brain microstructural (diffusion tensor) analysis. The work presented here aims to remedy two common problems that exist with the current state of the art approaches: 1) variance in scanner and protocol in data collection can limit the researcher's ability to harmonize data acquired under different conditions or using different clinical …

Complications Of Tavr From An Anesthesia Perspective, David R. Kingery Jr., Alex Roberts, Derek Horstemeyer, Russell Stahl

HCA Healthcare Journal of Medicine

Transcatheter aortic valve replacement (TAVR) has become the predominant technique for aortic valve replacement in the United States. Initially approved for high surgical risk patients, TAVR is now approved for most patients requiring valve therapy, including younger, lower-risk patients. The procedure is ideally performed in a hybrid operating room equipped with fluoroscopic equipment and transesophageal echocardiogram (TEE) imaging that can be viewed simultaneously by the operating team. The operating room should also be equipped to allow initiation of cardiopulmonary bypass, if necessary. Cardiac anesthesia teams are often involved with the management of these patients. This mini-review is designed to summarize …

In this study, we have investigated the association between the baseline gene expression profile in periapical granuloma and periapical wound healing after surgical endodontic treatment. Twenty-seven patients aged between 15 and 57 years underwent periapical surgery. The retrieved periapical tissue sample was used for mRNA expression analysis of COL1A1, VTN, ITGA5, IL-4, TNF, ANGPT, VEGFA, and CTGF. All patients were recalled after 6 and 12 months for periapical healing evaluation. Healing was then correlated with baseline gene expression. Healing was observed in 15 patients at the end of 6 months, which increased to 21 patients after 12 months. Six patients …

Fibrodysplasia ossificans progressiva (FOP) is a rare and devastating genetic disease, in which soft connective tissue is converted into heterotopic bone through an endochondral ossification process. Patients succumb early as they gradually become trapped in a second skeleton of heterotopic bone. Although the underlying genetic defect is long known, the inherent complexity of the disease has hindered the discovery of effective preventions and treatments. New developments in the gene therapy field have motivated its consideration as an attractive therapeutic option for FOP. However, the immune system's role in FOP activation and the as-yet unknown primary causative cell, are crucial issues …

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has resulted in a global pandemic with severe socioeconomic effects. Immunopathogenesis of COVID-19 leads to acute respiratory distress syndrome (ARDS) and organ failure. Binding of SARS-CoV-2 spike protein to human angiotensin-converting enzyme 2 (hACE2) on bronchiolar and alveolar epithelial cells triggers host inflammatory pathways that lead to pathophysiological changes. Proinflammatory cytokines and type I interferon (IFN) signaling in alveolar epithelial cells counter barrier disruption, modulate host innate immune response to induce chemotaxis, and initiate the resolution of inflammation. Here, we discuss experimental models to study SARS-CoV-2 …

Pharmacological Interventions For The Treatment And Control Of Shivering In Adult Patients Undergoing Elective Surgery Under Regional Anaesthesia: A Systematic Review And Meta-Analysis, Malika Hameed, Naureen Akber Ali, Khalid Ahsan, Mohsin Nazir

Department of Anaesthesia

Intraoperative shivering is quite common after regional anaesthesia, which not only increases the total body oxygen requirement but also causes discomfort to the patients. The aim of this systematic review is to determine the effectiveness of pharmacological agents administered intra-operatively for treating shivering in adult patients who are undergoing elective surgery under regional (i.e., central neuraxial) anaesthesia so that an optimal choice of an agent can be recommended for clinical application. A literature search was carried out using PubMed, Cochrane Library, CINAHL databases, and hand searches to identify relevant studies. After literature screening and information extraction, a systematic review was …

Case Report On Peri-Operative Surgical And Anaesthetic Management Of Ruptured Humongous Lung Abscess, Khalid Maudood Siddiqui, Akbar Azizullah, Muhammad Saad Yousuf

Department of Anaesthesia

Introduction: Early thoracic empyema is usually treated through video-assisted thoracoscopic (VATS) decortication. Patient selection is important for decortication if an effective surgical outcome is required. Lung isolation techniques are required to provide anesthesia for these patients to facilitate the surgeon while operating on the affected lung. The ultimate target is to protect the non-diseased contra-lateral lung from contamination.
Presentation of case: We are presenting a unique case of 20-year-old female, resident of Karachi, who was brought to the emergency room (ER) with signs of sepsis, hypotension, and multi-organ failure. She was brought to the operating room to undergo video-assisted thoracoscopy …

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 …

BACKGROUND: Cardiac surgery studies have established the clinical relevance of personalised arterial blood pressure management based on cerebral autoregulation. However, variabilities exist in autoregulation evaluation. We compared the association of several cerebral autoregulation metrics, calculated using different methods, with outcomes after cardiac surgery.

METHODS: Autoregulation was measured during cardiac surgery in 240 patients. Mean flow index and cerebral oximetry index were calculated as Pearson's correlations between mean arterial pressure (MAP) and transcranial Doppler blood flow velocity or near-infrared spectroscopy signals. The lower limit of autoregulation and optimal mean arterial pressure were identified using mean flow index and cerebral oximetry index. …

Podium Presentation: Continuous Labor Epidural Placement Trends Among Parturients: An Evidence-Based Practice Project, Aleksandr A. Lyakhov, Teresa Bigand, Amanda Affleck, Kenn Daratha, Kris Daratha

2022 Providence Nurse Research Conference

Background:

Childbirth is very painful, and unmanaged pain may reduce patient satisfaction or lead to other complications. Evidence indicates that pain severity is lower among parturient women administered analgesia via a continuous labor epidural (CLE) and that maternal request is sufficient indication for CLE placement to manage labor pain. In some cases, a medical induction of labor may be scheduled, offering an opportunity for proactive pain management from hospital staff. Yet, trends on timing of CLE placement among parturient women with scheduled labor induction versus spontaneous labor in hospitals in Eastern Washington at one health system are unclear.

Purpose:

The …

Medical Student Research Symposium

INTRODUCTION: Diagnostic medial branch blocks (MBB) confirm whether the origin of lower back pain is the facet joint, but are prone to false positive results. This study investigates the effects of midazolam sedation on perceived intensity of pain relief following lumbar MBB and determines the frequency of positive results in sedated patients for the corresponding treatment, radiofrequency thermocoagulation (RFTC).

METHODS: This prospective observational study compares pain scores between patients who undergo the MBB procedure with midazolam sedation (treatment) and without (control). Participants reported baseline and post-injection NRS pain scores, and 4, 8 weeks post-RFTC. If >80% pain relief was achieved …

The New Ropanasuri Journal of Surgery

The Coronavirus disease 2019 (COVID-19) pandemic impacts pulmonary cancer management since it shares similar clinical features and creates fear among patients to visit hospitals due to possible in-hospital disease transmission. We report a patient who presented with a rare case of a pulmonary neuroendocrine tumor with an ocular involvement, which, unfortunately, experienced a delay in diagnostics. The first hospitalization was due to superior vena cava syndrome, pleural and pericardial effusions, and swollen left eye. The patient was diagnosed with pulmonary cancer, released after the symptoms were relieved, and expected to visit a referral hospital for further diagnostics and treatments. The …

Validation Of A Whole Genome Methylation Profiling Classifier For Central Nervous System Tumors, Lucas Santana-Santos, Kwok Ling Kam, David Dittman, Stephanie De Vito, Matthew Mccord, Pouya Jamshidi, Hailie Fowler, Xinkun Wang, Alan Aalsburg, Daniel Brat, Craig Horbinski, Lawrence Jennings

Conference Presentation Abstracts

Whole genome methylation profiling is proving to be an incredibly powerful tool to diagnose tumors that are otherwise difficult to classify by histopathology and sequencing. The reference library of tumor DNA methylation data, using a machine learning-based tumor classifier, was developed by the German Cancer Research Network (DKFZ), and is available publicly on a research basis. However, medical institutions desiring to implement that classifier for routine clinical care need to import, adapt, and validate the classifier internally. We did this for our own DNA methylation-based classifier of central nervous system (CNS) tumors, using the same training and validation datasets as …
