INTRODUCTION: The spleen is a responsible significant part of the immune system; after Splenectomy following trauma, the immune system changes; splenic autotransplantation can preserve the immune system after trauma and Splenectomy. BACKGROUND: Patients can be protected from immune dysfunction by autotransplanting splenic tissues after splenectomy following trauma because their immune systems and spleens are changed. Patients can gain their immune function after splenic autotransplantation. METHODS: Patient classification methods are into three categories, Group A, 6 cases with auto-translation; Group B, 6 cases without transplantation; Group C, seven regular people serving as the control. AIM OF WORK: The aim of the work is not to compare outcome methods or compare types of autotransplantation; This work aims to document postoperative radiological, immunological, clinical, and hematological investigations. We concentrated on the results of investigations more than the types of operation or approach or types of autotransplantation. RESULTS: We showed that, after comparing each group with normal individuals subjects, patients who did not undergo autotransplantation had significantly higher platelet counts, a more significant percentage of micronucleated reticulocytes, increased levels of naive B lymphocytes, changes in class-switched memory and class-unswitched memory B cells, and higher levels of PD1 on CD8 + T lymphocytes. Nevertheless, neither splenic autotransplant patients nor the average general population showed any appreciable variations in any of the parameters. CONCLUSIONS: Spleen's activities with adequate hemocatheter activity and recovery of the immunological deficit after splenic autotransplantation.

BACKGROUND: Obesity is a severe health problem. Gallstones may symptomatize after sleeve gastrectomy (SG). Concomitant laparoscopic cholecystectomy (LC) with SG is controversial. The effects of SG and LC versus delayed LC following SG in obese patients with asymptomatic gallbladder stones were evaluated. METHODS: A randomized trial of 222 morbidly obese patients with gallbladder stones divided them into two equal groups: SG + LC and SG-only. This multicenter study conducted from January 2016 to January 2019. RESULTS: Except for operative time and postoperative hospital stay, there was no statistically significant difference between LSG + LC group and SG group (P < 0.001). In SG + LC group, LC added 40.7 min to SG, three patients (3%) required conversion, early postoperative complications occurred in 9 cases (9/111, 9%), three cases required re-intervention (3%). In SG group, the complicated cases required LC were 61 cases (61/111, 55%). Acute cholecystitis (26/61, 42.7%) was the most common gallstone symptoms. Most complicated cases occurred in the first-year follow-up (52/61, 85%). In the delayed LC group (61 patients), operative time was 50.13 ± 1.99 min, open conversion occurred in 2 cases (2/61, 3.2%), early postoperative complications occurred in four patients (4/61, 6.4%) and postoperative re-intervention were due to bile leaks and cystic artery bleeding (2/61, 3.2%). CONCLUSIONS: SG with LC prolongs the operative time and hospital stay, but the perioperative complications are the same as delayed LC; LC with SG minimizes the need for a second surgery. Concomitant LC with SG is safe.

OBJECTIVES: In the early stages of the COVID-19 pandemic, there were significant concerns about the infectious risks of intubation to healthcare providers. In response, a dedicated emergency response intubation team (ERIT) consisting of anesthesiologists and allied health providers was instituted for our emergency department (ED). Given the high-risk nature of intubations and the new interprofessional team dynamics, we sought to assess health-care provider experiences and potential areas of improvement. METHODS: Surveys were distributed to healthcare providers at the University Health Network, a quaternary healthcare centre in Toronto, Canada, which includes two urban EDs seeing over 128,000 patients per year. Participants included ED physicians and nurses, anesthesiologists, anesthesia assistants, and operating room nurses. The survey included free-text questions. Responses underwent thematic analysis using grounded theory and were independently coded by two authors to generate descriptive themes. Discrepancies were resolved with a third author. Descriptive themes were distilled through an inductive, iterative process until fewer main themes emerged. RESULTS: A total of 178 surveys were collected (68.2% response rate). Of these, 123 (69%) participated in one or more ERIT activations. Positive aspects included increased numbers of staff to assist, increased intubation expertise, improved safety, and good team dynamics within the ERIT team. Challenges included a loss of scope (primarily ED physicians and nurses) and unfamiliar workflows, perceived delays to ERIT team arrival or patient intubation, role confusion, handover concerns, and communication challenges between ED and ERIT teams. Perceived opportunities for improvement included interprofessional training, developing clear guidelines on activation, inter-team role clarification, and guidelines on handover processes post-intubation. CONCLUSIONS: Healthcare providers perceived that a novel interprofessional collaboration for intubations of COVID-19 patients presented both benefits and challenges. Opportunities for improvement centred around interprofessional training, shared decision making between teams, and structured handoff processes.


RéSUMé: OBJECTIFS: Aux premiers stades de la pandémie de COVID-19, les risques infectieux de l'intubation pour les prestataires de soins de santé ont suscité de vives inquiétudes. En réponse, une équipe d'intervention d'urgence en intubation (emergency response intubation team ERIT), composée d'anesthésistes et de prestataires de services paramédicaux, a été mise en place dans notre service d'urgence. Compte tenu de la nature à haut risque des intubations et de la nouvelle dynamique d'équipe interprofessionnelle, nous avons cherché à évaluer les expériences des prestataires de soins et les domaines d'amélioration potentiels. MéTHODES: Les questionnaires ont été distribués aux prestataires de soins de santé du University Health Network, un centre de soins de santé quaternaire de Toronto, au Canada, qui comprend deux urgences urbaines accueillant plus de 128 000 patients par an. Les participants comprenaient des médecins et des infirmiers des urgences, des anesthésistes, des assistants en anesthésie et des infirmiers de salle d'opération. Les réponses ont fait l'objet d'une analyse thématique fondée sur la théorie de la base et ont été codées indépendamment par deux auteurs afin de générer des thèmes descriptifs. Les divergences ont été résolues avec un troisième auteur. Les thèmes descriptifs ont été distillés par un processus inductif et itératif jusqu'à ce qu'un nombre réduit de thèmes principaux émerge. RéSULTATS: Au total, 178 sondages ont été recueillis (taux de réponse de 68,2 %). Parmi ceux-ci, 123 (69 %) ont participé à une ou plusieurs activations d'ERIT. Les aspects positifs comprenaient un nombre accru de personnel pour aider, une expertise accrue en matière d'intubation, une sécurité améliorée et une bonne dynamique d'équipe au sein de l'équipe ERIT. Parmi les difficultés rencontrées, citons la perte du champ d'action (principalement les médecins et les infirmières des services d'urgence) et les flux de travail non familiers, les retards perçus dans l'arrivée de l'équipe d'ERIT ou l'intubation du patient, la confusion des rôles, les problèmes de transfert et les difficultés de communication entre les équipes des services d'urgence et d'ERIT. Les possibilités d'amélioration perçues comprennent la formation interprofessionnelle, l'élaboration de directives claires sur l'activation, la clarification des rôles entre les équipes et les directives sur les processus de transfert après l'intubation. CONCLUSIONS: Les prestataires de soins de santé ont perçu qu'une nouvelle collaboration interprofessionnelle pour les intubations des patients COVID-19 présentait à la fois des avantages et des défis.

BACKGROUND: The COVID-19 pandemic has been associated with ST-Elevation Myocardial Infarction (STEMI) reperfusion delays despite reduced emergency department (ED) volumes. However, little is known about ED contributions to these delays. We sought to measure STEMI delays and ED quality benchmarks over the course of the first two waves of the pandemic. STUDY: This study was a multi-centre, retrospective chart review from two urban, academic medical centres. We obtained ED volumes, COVID-19 tests and COVID-19 cases from the hospital databases and ED Code STEMIs with culprit lesions from the cath lab. We measured door-to-ECG (DTE) time and ECG-to-Activation (ETA) time during the phases of the pandemic in our jurisdiction: pre-first wave (Jan-Mar 2020), first wave (Apr-June 2020), post-first wave (July-Nov 2020), and second wave (Dec 2020 to Feb 2021). We calculated median DTE and ETA times and compared them to the 2019 baseline using Wilcox rank-sum test. We calculated the percentages of DTE ≤10 min and of ETA ≤10 min and compared them to baseline using chi-square test. We also utilized Statistical Process Control (SPC) Xbar-R charts to assess for special cause variation. RESULTS: COVID-19 cases began during the pre-wave phase, but there was no change in ED volumes or STEMI quality metrics. During the first wave ED volumes fell by 40%, DTE tripled (10.0 to 29.5 min, p = 0.016), ETA doubled (8.5 to 17.0 min, p = 0.04), and percentages for both DTE ≤10 min and ETA ≤10 min fell by three-quarters (each from more than 50%, to both 12.5%, both p < 0.05). After the first wave all STEMI quality benchmarks returned to baseline and did not significantly change during the second wave. A brief period of special cause variation was noted for DTE during the first wave. CONCLUSIONS: Both DTE and ETA metrics worsened during the first wave of the pandemic, revealing how it negatively impacted the triage and diagnosis of STEMI patients. But these normalized after the first wave and were unaffected by the second wave, indicating that nurses and physicians adapted to the pandemic to maintain STEMI quality of care. DTE and ETA metrics can help EDs identify delays to reperfusion during the pandemic and beyond.

BACKGROUND: Limits to ST-Elevation Myocardial Infarction (STEMI) criteria may lead to prolonged diagnostic time for acute coronary occlusion. We aimed to reduce ECG-to-Activation (ETA) time through audit and feedback on STEMI-equivalents and subtle occlusions, without increasing Code STEMIs without culprit lesions. METHODS: This multi-centre, quality improvement initiative reviewed all Code STEMI patients from the emergency department (ED) over a one-year baseline and one-year intervention period. We measured ETA time, from the first ED ECG to the time a Code STEMI was activated. Our intervention strategy involved a grand rounds presentation and an internal website presenting weekly local challenging cases, along with literature on STEMI-equivalents and subtle occlusions. Our outcome measure was ETA time for culprit lesions, our process measure was website views/visits, and our balancing measure was the percentage of Code STEMIs without culprit lesions. RESULTS: There were 51 culprit lesions in the baseline period, and 64 in the intervention period. Median ETA declined from 28.0 min (95% confidence interval [CI] 15.0-45.0) to 8.0 min (95%CI 6.0-15.0). The website garnered 70.4 views/week and 27.7 visitors/week in a group of 80 physicians. There was no change in percentage of Code STEMIs without culprit lesions: 28.2% (95%CI 17.8-38.6) to 20.0% (95%CI 11.2-28.8%). Conclusions Our novel weekly web-based feedback to all emergency physicians was associated with a reduction in ETA time by 20 min, without increasing Code STEMIs without culprit lesions. Local ECG audit and feedback, guided by ETA as a quality metric for acute coronary occlusion, could be replicated in other settings to improve care.

INTRODUCTION: Sulfiredoxin (Srx), which is an endogenous antioxidant substance which could, regulate the signaling pathways of reactive oxygen species. Nuclear factor erythroid 2-related factor 2 (Nrf2) is Cap-N-collar (CNC) transcription factors family member that have essential roles in regulation of antioxidant response. The transcription factor PROX1 is a transcription factor and a key regulatory protein in cancer development. AIM OF THE STUDY: To analyze levels of tissue expression of Srx, Nrf2, and PROX1 in gastric cancer and adjacent non-neoplastic gastric mucosa to clarify the relationship between their expression levels, clinical, pathological parameters and patients' outcome. The results might lead to discovering novel targeted therapies to gastric cancers. MATERIAL AND METHODS: We included 70 paraffin-embedded samples: 50 specimens from gastric carcinomas and 20 specimens from adjacent non-neoplastic gastric mucosa. All samples are stained with Srx, Nrf2, and PROX1 using immunohistochemistry, correlated their expression with clinicopathological and prognostic parameters of patients. RESULTS: High levels of Srx and Nrf2 expression were positively associated with higher cancer grade (p = 0.006, 0.031 respectively), advanced stage (p < 0.001, 0.02 respectively), higher incidence of distant metastases (p = 0.029, 0.03 respectively) and dismal outcome (p < 0.001). High levels of PROX1 expression were associated with lower cancer grade (p = 0.005), absence of lymph nodes metastases (p = 0.023), early stage (p = 0.003), absence of relapse (p = 0.004), and favorable outcome (p < 0.001). CONCLUSIONS: Srx and Nrf2 expression increase gastric cancer invasiveness, suggesting their utility as poor prognostic markers, but PROX1 serves as a favorable prognostic marker of gastric cancer patients.
