Simulation in airway management teaching and training.

There is a gradual shift in training and teaching methods in the medical field. We are slowly moving from the traditional model and adopting active learning methods like simulation-based training. Airway management is an essential clinical skill for any anaesthesiologist, and a trained anaesthesiologist must perform quick and definitive airway management using various techniques. Airway simulations have been used for the past few decades. It ensures active involvement, upgrading the trainees' airway management knowledge and skills, including basic airway skills, invasive procedures, and difficult clinical scenarios. Trainees also learn non-technical skills such as communication, teamwork, and coordination. A wide range of airway simulators are available. However, texture surface characteristics vary from one type to another. The simulation-based airway management training requires availability, understanding, faculty development, and a structured curriculum for effective delivery. This article explored the available evidence on simulation-based airway management teaching and training.

Simcrafting: A comprehensive framework for scenario development for simulation.

Simulation can be an excellent teaching and learning method if the scenarios are created appropriately. It starts with assessing the learner's needs and is followed by laying down objectives embracing the SMART principles. While creating a scenario, it is essential to consider the different aspects of realism, such as physical, contextual and psychological aspects. Using moulages and props helps in creating physical realism. The simulation expert should also be aware of the learner's experience and decide the SimZones for their learners based on their level of clinical expertise. The scenario progression needs to be laid down in stages. The role of the embedded participant needs to be decided a priori, and the embedded participant should be well-versed in their role. Pilot testing is a crucial step in simulation development as it keeps the simulation expert aware of the loopholes in the simulation scenario before running.

Severe Anaplasmosis With Multiorgan Involvement in a Rheumatoid Arthritis Patient.

Anaplasmosis, caused by the tick-borne bacterium Anaplasma phagocytophilum, is an emerging infectious disease with a broad spectrum of clinical manifestations. Here, we present a case report of a 66-year-old Caucasian woman residing in Connecticut who exhibited severe anaplasmosis with multi-organ involvement. The patient, with a medical history of rheumatoid arthritis and hypothyroidism, presented with confusion, lethargy, fever, myalgia, generalized weakness, and poor appetite in May 2023. Laboratory investigations revealed pancytopenia, hyponatremia, elevated liver enzymes with mild hyperbilirubinemia, and lactic acidosis. A buffy coat smear analysis demonstrated basophilic intracytoplasmic inclusion bodies in the neutrophils, supporting the diagnosis of severe anaplasmosis. Prompt administration of doxycycline, the recommended treatment for anaplasmosis, was initiated. However, the patient subsequently developed acute respiratory distress syndrome (ARDS) necessitating heated humidified high-flow nasal cannula (HFNC) therapy. Anaplasma polymerase chain reaction (PCR) confirmed the presence of the bacterium in the patient's blood. Following doxycycline treatment, the patient demonstrated improvement in peripheral blood findings, resolution of ARDS, and complete neurologic recovery. This case underscores the potential severity and diverse clinical manifestations of anaplasmosis, highlighting the importance of early recognition, prompt diagnosis, and timely initiation of appropriate treatment to prevent severe complications and improve patient outcomes.

Community engagement education in academic health centers, colleges, and universities.

Community engagement (CE) is critical for advancing health equity and a key approach for promoting inclusive clinical and translational science. However, it requires a workforce trained to effectively design, implement, and evaluate health promotion and improvement strategies through meaningful collaboration with community members. This paper presents an approach for designing CE curricula for research, education, clinical care, and public health learners. A general pedagogical framework is presented to support curriculum development with the inclusion of community members as facilitators or faculty. The overall goal of the curriculum is envisioned as enabling learners to effectively demonstrate the principles of CE in working with community members on issues of concern to communities to promote health and well-being. We highlight transformations needed for the commonly used critical service-learning model and the importance of faculty well-versed in CE. Courses may include didactics and practicums with well-defined objectives and evaluation components. Because of the importance of building and maintaining relationships in CE, a preparatory phase is recommended prior to experiential learning, which should be guided and designed to include debriefing and reflective learning. Depending on the scope of the course, evaluation should include community perspectives on the experience.

Neuroprotective effect of Mulmina Mango against chemotherapy-induced cognitive decline in mouse model of mammary carcinoma.

The post-treatment status of breast cancer survivors has become a concern because of the toxicity induced by chemotherapeutic agents in the brain tissues resulting in cognitive deficits, which is generally referred as chemobrain. The aim of this study was to assess the effect of a proprietary ayurvedic formulation Mulmina Mango against chemotherapy-induced cognitive impairment (CICI). Mammary carcinoma was induced by subcutaneously inoculating 4T1 cells into the mammary fat pad of the animals. Intraperitoneal administration of Cyclophosphamide, Methotrexate, 5-Fluorouracil (CMF) regimen was carried out once a week for three weeks. Treatment of Mulmina began one week before chemotherapy and continued till the end of the chemotherapy cycle. After three cycles of chemotherapy, cognitive decline was assessed by Morris water maze task followed by assessment of locomotor activity by open-field test. Tumor progression was evaluated by measurement of tumor volume. Oxidative and neuroinflammatory markers were also evaluated from the isolated brain samples. CMF treatment resulted in a considerable reduction in tumour volume. We found chemotherapy negatively affected behavioral and biochemical parameters in animals and Mulmina treatment ameliorated these cognitive impairments by restoring antioxidant and maintaining cytokine levels. The combination of phytochemicals in Mulmina proved its possible ability to alleviate CICI without affecting chemotherapeutic efficiency and could pave the way for identifying treatment strategies to combat chemobrain.

A comparative evaluation of Airtraq and Hansraj Video laryngoscopes in patients undergoing tracheal intubation with cervical spine immobilization - A randomized prospective study.

BACKGROUND AND AIMS: Airway management is a key concern in trauma patients with cervical spine fracture. Application of manual inline axial stabilization (MIAS) has become the standard of care in these patients. Indirect laryngoscopy only requires alignment of the pharyngeal and laryngeal axis. Hence the primary objective of the study was to compare two indirect laryngoscopes, Airtraq (with adaptor) and Hansraj Video laryngoscopes based on its Intubation Difficulty Score. MATERIAL AND METHODS: Sixty anesthetized patients were divided into two groups using computer-based randomization, and tracheal intubation was performed using either Airtraq or Hansraj Videolaryngoscope with cervical spine immobilization. RESULTS: Both Airtraq and Hansraj groups were comparable in terms of percentage of glottic opening (POGO) scoring (92 ± 9.88% vs. 89.3 ± 10.4%.) and duration of intubation attempt (14.9 ± 4.36 sec vs. 16.97 ± 3.64 sec). Intubation difficulty scale (IDS) score was significantly shorter with Airtraq (1 ± 0.58 vs. 1.8 ± 0.805; P < 0.0001). The mean duration of time taken for laryngoscopy in Airtraq (12.9 ± 2.07 s vs. 19.06 ± 3.83 s; P < 0.0001)) was significantly shorter and also the duration of time taken to secure airway in Airtraq VL was significantly shorter (29.47 ± 4.75 s vs. 36.03 ± 5.80 sec; P < 0.0001). The heart rate and MABP changes were modest in both groups, but was significantly more in Hansraj VL as compared to Airtraq VL, post-intubation. CONCLUSION: Both Airtraq and Hansraj videolaryngoscope can be used as first-hand device in the scenario of cervical spine stabilization. Airtraq videolaryngoscope is better than Hansraj videolaryngoscope due to shorter IDS and lessor hemodynamic changes.

Post-traumatic brain injury antithrombin III recovers Morris water maze cognitive performance, improving cued and spatial learning.

BACKGROUND: Neuroinflammation and cerebral edema development following severe traumatic brain injury (TBI) affect subsequent cognitive recovery. Independent of its anticoagulant effects, antithrombin III (AT-III) has been shown to block neurovascular inflammation after severe TBI, reduce cerebral endothelial-leukocyte interactions, and decrease blood-brain barrier permeability. We hypothesized that AT-III administration after TBI would improve post-TBI cognitive recovery, specifically enhancing learning, and memory. METHODS: Fifteen CD1 male mice were randomized to undergo severe TBI (controlled cortical impact [CCI]: velocity, 6 m/s; depth, 1 mm; diameter, 3 mm) or sham craniotomy and received either intravenous AT-III (250 IU/kg) or vehicle (VEH/saline) 15 minutes and 24 hours post-TBI. Animals underwent Morris water maze testing from 6 to 14 days postinjury consisting of cued learning trials (platform visible), spatial learning trials (platform invisible, spatial cues present), and probe (memory) trials (platform removed, spatial cues present). Intergroup differences were assessed by the Kruskal-Wallis test (p < 0.05). RESULTS: Morris water maze testing demonstrated that cumulative cued learning (overall mean time in seconds to reach the platform on days 6-8) was worst in CCI-VEH animals (26.1 ± 2.4 seconds) compared with CCI-AT-III counterparts (20.3 ± 2.1 seconds, p < 0.01). Cumulative noncued spatial learning was also worst in the CCI-VEH group (23.4 ± 1.8 seconds) but improved with AT-III (17.6 ± 1.5 seconds, p < 0.01). In probe trials, AT-III failed to significantly improve memory ability. Animals that underwent sham craniotomy demonstrated preserved learning and memory compared with all CCI counterparts (p < 0.05). CONCLUSION: Antithrombin III improves neurocognitive recovery weeks after TBI. This improvement is particularly related to improvement in learning but not memory function. Pharmacologic support of enhanced learning may support new skill acquisition or relearning to improve outcomes after TBI. LEVEL OF EVIDENCE: Therapeutic/care management, level II.

Antithrombin III ameliorates post-traumatic brain injury cerebral leukocyte mobilization enhancing recovery of blood brain barrier integrity.

BACKGROUND: Acute traumatic coagulopathy often accompanies traumatic brain injury (TBI) and may impair cognitive recovery. Antithrombin III (AT-III) reduces the hypercoagulability of TBI. Antithrombin III and heparinoids such as enoxaparin (ENX) demonstrate potent anti-inflammatory activity, reducing organ injury and modulating leukocyte (LEU) activation, independent of their anticoagulant effect. It is unknown what impact AT-III exerts on cerebral LEU activation and blood-brain barrier (BBB) permeability after TBI. We hypothesized that AT-III reduces live microcirculatory LEU-endothelial cell (EC) interactions and leakage at the BBB following TBI. METHODS: CD1 mice (n = 71) underwent either severe TBI (controlled cortical impact (CCI), 6-m/s velocity, 1-mm depth, and 4-mm diameter) or sham craniotomy and then received either AT-III (250 IU/kg), ENX (1.5 mg/kg), or vehicle (saline) every 24 hours. Forty-eight hours post-TBI, cerebral intravital microscopy visualized in vivo penumbral microvascular LEU-EC interactions and microvascular leakage to assess BBB inflammation/permeability. Body weight loss and the Garcia neurological test (motor, sensory, reflex, balance) served as surrogates of clinical recovery. RESULTS: Both AT-III and ENX similarly reduced in vivo penumbral LEU rolling and adhesion (p < 0.05). Antithrombin III also reduced live BBB leakage (p < 0.05). Antithrombin III animals demonstrated the least 48-hour body weight loss (8.4 ± 1%) versus controlled cortical impact and vehicle (11.4 ± 0.5%, p < 0.01). Garcia neurological test scores were similar among groups. CONCLUSION: Antithrombin III reduces post-TBI penumbral LEU-EC interactions in the BBB leading to reduced neuromicrovascular permeability. Antithrombin III further reduced body weight loss compared with no therapy. Further study is needed to determine if these AT-III effects on neuroinflammation affect longer-term neurocognitive recovery after TBI.

Indian Resuscitation Council (IRC) suggested guidelines for Comprehensive Cardiopulmonary Life Support (CCLS) for suspected or confirmed coronavirus disease (COVID-19) patient.

Management of the recent outbreak of the novel coronavirus disease (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) remains challenging. The challenges are not only limited to its preventive strategies, but also extend to curative treatment, and are amplified during the management of critically ill patients with COVID-19. Older persons with comorbidities like diabetes mellitus, cardiac diseases, hepatic impairment, renal disorders and respiratory pathologies or immune impairing conditions are more vulnerable and have a higher mortality from COVID-19. Earlier, the Indian Resuscitation Council (IRC) had proposed the Comprehensive Cardiopulmonary Life Support (CCLS) for management of cardiac arrest victims in the hospital setting. However, in patients with COVID-19, the guidelines need to be modified,due to various concerns like differing etiology of cardiac arrest, virulence of the virus, risk of its transmission to rescuers, and the need to avoid or minimize aerosolization from the patient due to various interventions. There is limited evidence in these patients, as the SARS-CoV-2 is a novel infection and not much literature is available with high-level evidence related to CPR in patients of COVID-19. These suggested guidelines are a continuum of CCLS guidelines by IRC with an emphasis on the various challenges and concerns being faced during the resuscitative management of COVID-19 patients with cardiopulmonary arrest.

Isolated Nonspecific Colonic Ulcer: A Case Report From a Tertiary Care Hospital in Pakistan.

Simple, isolated nonspecific colonic ulcer (NSCU) is a rare pathological entity which has not been adequately explored in the past literature. It is predominant between the ages of 40 and 60 years, and the most common complication is perforation which can be life threatening. Here we present a case of a young female who presented with a perforated NSCU and was successfully managed surgically.

Correlation Between Body Mass Index and Fibroadenoma.

Introduction Among all benign conditions, the fibroadenoma is the most common lesion worldwide as well as in Pakistan. Clinicians often face the dilemma of whether to remove the mass or to monitor it by means of periodic follow-up examinations. Although the removal of these lesions is a definitive solution, surgery may involve unnecessary excision of benign lesions and unbecoming cosmesis. Body mass index (BMI) is a known risk factor for the development of breast cancer.However, the relationship between BMI and benign breast diseases is still unclear. Some studies showed that increased BMI is a risk factor for benign breast diseases; however, a large number of studies showed that a decrease in BMI is the risk factor for benign breast diseases. Material and methods This was a descriptive cross-sectional study conducted at the Department of General Surgery, Pakistan Institute of Medical Sciences (PIMS), Shaheed Zulfiqar Ali Bhutto Medical University, Islamabad, Pakistan. All patients fulfilling inclusion criteria were assessed in the breast clinic of PIMS. A final diagnosis of fibroadenoma was made after a triple assessment. Weight in kilograms and height in meters were measured. All the information was recorded in a specifically designed proforma accordingly by the postgraduate trainee. BMI was calculated by the formula: BMI=Weight in kgs/height in meters. Other variables that were noted include patients' age, gender, contact number, and hospital visit. The data were analyzed using SPSS version 21 (IBM Corp., Armonk, NY, US). Results The BMI of study patients was 21.8 ± 1.3, ranging from 19 to 24.9. Out of 300 patients presenting with benign breast disease, 60 (20%) had a fibroadenoma while 240 (80%) had other benign breast diseases. Out of 136 patients with high BMI, 42 (30.8%) had a fibroadenoma while out of 74 patients with low BMI, eight (10.8%) had a fibroadenoma; however, out of 90 patients with normal BMI, 10 (11.1%) had a fibroadenoma. Our study population showed an increased risk of fibroadenoma formation in the adolescent age group with an OR value of 8.54 (CI 4.38-16.63, P<0.001). There were also additional statistical correlations between higher BMI and the site of the lesion being the upper outer quadrant of the breast (t= 4.326 P<0.01). There was no significant correlation of BMI with size and increased number of lesions (P=0.280 and P=0.175). Conclusion High BMI seems to be a substantial risk factor for the development of a fibroadenoma, particularly in young adolescent females.

Measuring institutional community engagement: Adding value to academic health systems.

Beyond medical schools' historical focus on pillar missions including clinical care, education, and research, several medical schools now include community engagement (CE) as a mission. However, most academic health systems (AHSs) lack the tools to provide metrics, evaluation, and standardization for quantifying progress and contributions of the CE mission. Several nationwide initiatives, such as that driven by the Institute of Medicine recommending advances in CE metrics at institutions receiving Clinical and Translational Science Awards, have encouraged the research and development of systematic metrics for CE, but more progress is needed. The CE components practical model provides a foundation for analyzing and evaluating different types of CE activities at AHSs through five components: research, education, community outreach and community service, policy and advocacy, and clinical care. At the Medical College of Wisconsin (MCW), an annual survey administered to faculty and staff assessed the types and number of CE activities from the prior year. Survey results were combined to create a CE report for departments across the institution and inform MCW leadership. Insights gathered from the survey have contributed to next steps in CE tracking and evaluation, including the development of a CE dashboard to track CE activities in real time. The dashboard provides resources for how individuals can advance the CE mission through their work and guide CE at the institutional level.

Cerebral Edema and Neurological Recovery after Traumatic Brain Injury Are Worsened if Accompanied by a Concomitant Long Bone Fracture.

Progression of severe traumatic brain injury (TBI) is associated with worsening cerebral inflammation, but it is unknown how a concomitant bone fracture (FX) affects this progression. Enoxaparin (ENX), a low molecular weight heparin often used for venous thromboembolic prophylaxis, decreases penumbral leukocyte (LEU) mobilization in isolated TBI and improves neurological recovery. We investigated if TBI accompanied by an FX worsens LEU-mediated cerebral inflammation and if ENX alters this process. CD1 male mice underwent controlled cortical impact (CCI) or sham craniotomy with or without an open tibial FX, and received either ENX (1 mg/kg, three times/day) or saline for 2 days following injury. Randomization defined four groups (Sham, CCI, CCI+FX, CCI+FX+ENX, n = 10/group). Two days after CCI, neurological recovery was assessed with the Garcia Neurological Test (GNT); intravital microscopy (LEU rolling and adhesion, microvascular leakage) and blood hemoglobin levels were also evaluated. Penumbral cerebral neutrophil sequestration (Ly-6G immunohistochemistry [IHC]) were evaluated post-mortem. In vivo LEU rolling was greater in CCI+FX (45.2 ± 4.8 LEUs/100 µm/min) than in CCI alone (26.5 ± 3.1, p = 0.007), and was suppressed by ENX (23.2 ± 5.5, p = 0.003 vs. CCI + FX). Neurovascular permeability was higher in CCI+FX (71.1 ± 2.9%) than CCI alone (42.5 ± 2.3, p < 0.001). GNT scores were lower in CCI+FX (15.2 ± 0.2) than in CCI alone (16.3 ± 0.3, p < 0.001). Hemoglobin was lowest in the CCI+FX+ENX group, lower than in Sham or CCI. IHC demonstrated greatest polymorphonuclear neutrophil (PMN) invasion in CCI+FX in uninjured cerebral territories. A concomitant long bone FX worsens TBI-induced cerebral LEU mobilization, microvascular leakage, and cerebral edema, and impairs neurological recovery at 48 h. ENX suppresses this progression but may increase bleeding.

A concomitant bone fracture delays cognitive recovery from traumatic brain injury.

BACKGROUND: Brain injury progression after severe traumatic brain injury (TBI) is associated with worsening cerebral inflammation but it is unknown how a concomitant bone fracture (BF) affects this progression. Enoxaparin (ENX) decreases penumbral leukocyte mobilization after TBI and improves neurologic recovery. We hypothesized that a concomitant BF worsens learning/memory recovery weeks after TBI and that ENX improves this recovery. METHODS: CD1 male mice underwent controlled cortical impact or sham craniotomy with or without tibial fracture, receiving either daily ENX (0.8 mg/kg) or saline for 14 days after injury. Randomization defined four groups (Sham, TBI only, TBI + Fx, TBI + Fx + ENX, n = 5/each). Body weight loss and neurologic recovery (Garcia Neurologic Test, max score = 18) were assessed each day. Mouse learning (swimming time [s] and total distance [m] to reach the submerged platform Days 14 to 17 after TBI) and memory (swimming time [s] in platform quadrant after platform removed [probe]) was assessed by the Morris water maze. Ly-6G (cerebral neutrophil sequestration) and glial fibrillary acidic protein were evaluated by immunohistochemistry in brain tissue post mortem. Analysis of variance with Tukey's post hoc test determined significance (p < 0.05). RESULTS: A concurrent BF worsened Garcia Neurologic Test scores post-TBI Days 2 to 4 (p < 0.01) as compared with TBI only, and ENX reversed this worsening on Day 4 (p < 0.01). Learning was significantly slower (greater swimming time and distance) in TBI + Fx versus TBI only on Day 17 (p < 0.01). This was despite similar swimming velocities in both groups, indicating intact extremity motor function. Memory was similar in isolated TBI and Sham which was significantly better than in TBI + Fx animals (p < 0.05). Glial fibrillary acidic protein-positive cells in penumbral cortex were most prevalent in TBI + Fx animals, significantly greater than in Sham (p < 0.05). CONCLUSION: A long BF accompanying TBI worsens early neurologic recovery and subsequent learning/memory. Enoxaparin may partially counter this and improve neurologic recovery.

Science Cafés: Transforming citizens to scientific citizens-What influences participants' perceived change in health and scientific literacy?

INTRODUCTION: Science Cafés facilitated by the Clinical and Translational Science Institute of Southeast Wisconsin seek to increase health and scientific literacy through informal conversation between researchers and community members. The goal was to understand what factors have the greatest influence on attendees' perceived changes in health and science literacy levels (PCHSL) to increase impact. METHODS: Previous research established the evaluation used in the Science Cafés to measure PCHSL. In this study, comparisons were made between (1) 2 different approaches to Science Cafés (Genomics Science Cafés or Health Science Cafés) and (2) regression models to show which factors best predicted PCHSL. RESULTS: The approach of the Genomics Science Cafés series to Science Cafés showed a larger impact on PCHSL. Regression models suggest SES and education significantly contributes to PCHSL. CONCLUSIONS: Insights for program development to have greater impact on PCHSL were identified. Continuing to optimize dissemination of research findings to the public is essential for improving community health and well-being.

Towards a practical model for community engagement: Advancing the art and science in academic health centers.

INTRODUCTION: Community engagement (CE) has become more prevalent among academic health centers (AHCs), with significant diversity in practices and language. The array of approaches to CE contributes to confusion among practitioners. METHODS: We have reviewed multiple models of CE utilized by AHCs, Clinical and Translational Science Awards, and higher education institutions overall. Taking these models into consideration, we propose a comprehensive model of CE that encompasses a broader spectrum of activities and programs. RESULTS: The CE Components Practical Model includes 5 components: Community Outreach and Service, Education, Clinical Care, Research, and Policy and Advocacy. The components are supported by the foundational elements within administrative functions and infrastructure. CONCLUSIONS: This model will accomplish the following: (1) reduce confusion about CE; (2) provide a broader understanding of CE; and (3) increase the ability of CE practitioners to interact with each other through this common reference and engage in advancing CE scholarship.

A prospective randomized control study comparing classic laryngeal mask airway with Guedel's airway for tracheal tube exchange and smooth extubation.

INTRODUCTION: Extubation in deep plane of anesthesia followed by Guedel's oropharyngeal airway (OPA™) insertion is a routine method to avoid hemodynamic changes associated with tracheal extubation. Exchange of endotracheal tube (ETT) with Classic laryngeal mask airway (LMA™) prior to emergence from anesthesia also serves similar purpose. We had compared the hemodynamic changes involved during this ETT/LMA™ and ETT/OPA™ exchange technique. MATERIAL AND METHODS: This was a randomized prospective study on ASA I and 2 patients undergoing elective surgery under general anesthesia. These patients were randomly divided into two groups i.e. OPA group and LMA group of 50 patients each. Hemodynamic parameters i.e. systolic blood pressure (SBP) and heart rate (HR) were recorded during exchange of ETT with OPA™ or LMA™. Coughing / bucking during removal of OPA™ and LMA™, and presence of post operative sore throat for both the groups were also graded and recorded. Data within the groups have been analyzed using paired "t" test while those between the groups were analyzed using unpaired "t" test. Chi square test was used to analyze grades of coughing and post operative sore throat. RESULTS: In both groups, hemodynamic parameters rose significantly as OPA™/LMA™ was placed (P < 0.05) and then started declining. Hemodynamic parameters continued to fall in LMA group after extubation. However in OPA group, hemodynamic parameters continued to rise even after extubation and declined only when OPA™ was removed. There was no statistical significant difference between the LMA and OPA group in respect to coughing and post operative sore throat. CONCLUSION: LMA™ is superior to OPA™ for exchange of ETT as it provides greater hemodynamic stability.
