Planning for a potential paediatric bronchiolitis surge: How Inter-Professional Education (IPE) was used to build a practice-ready clinical team

Introduction: Bronchiolitis is the most common cause for paediatric respiratory hospital admissions in young children in the UK.1 Following the relaxation of international SARS-Cov-2 lockdown measures a potential national surge in cases was predicted, highlighting a need for more collaborative working across core specialities.2 This prompted the use of the principles of Inter-Professional Education (IPE) to prepare and deliver an intervention to improve outcomes for these patients.3 Objectives: * To plan, deliver and evaluate an educational intervention focussed on improving the knowledge, skills and attitudes needed to care for a sick child with bronchiolitis * To utilise the principles of IPE to improve competence and confidence across core specialities involved in the care of a sick child with bronchiolitis Methods: A team from the Adult Intensive Care Unit (AICU) and the Paediatric High Dependency Unit (PHDU) from the Royal Berkshire Hospital in Reading delivered an inter-professional teaching session focussed on caring for the sick child with bronchiolitis. The patient journey was utilised as a framework to teach the core knowledge, skills and attitudes needed to clinically manage a child from the Emergency Department (ED) to the Intensive Care Unit (ICU). Each session included a lecture about bronchiolitis - describing pathophysiology and how to recognise the deteriorating child;a skills and drills tutorial - highlighting the need for weight-based calculations for high flow nasal oxygen, intravenous fluids and drugs;and a practical simulation scenario - focussing on the stabilisation and management of a sick child awaiting retrieval to the Paediatric Intensive Care Unit (PICU). Result(s): 135 healthcare professionals from a range of adult and paediatric disciplines involved in the care of children across the patient journey attended one of fourteen teaching sessions delivered between September to December 2021. Attendees completed a feedback questionnaire. One hundred and twenty-two (90%) reported an extremely high degree of satisfaction overall, with many saying they would recommend the teaching sessions to others. Areas of personal and professional development were highlighted across the following main themes: gaining theoretical knowledge;understanding key equipment;performing drug calculations;preparing for intubation and ventilation;assessing the need for chest physiotherapy techniques;and more collaborative team-working. Free text comments demonstrated that the attendees felt the teaching sessions: built confidence through the sharing of new or improved knowledge and skills;facilitated a safe space to practice using simulation;and provided the opportunity to learn about and from each other. Many of the attendees also commented on areas they wanted to reinforce and further develop in daily clinical practice as a direct result of the sessions. Conclusion(s): On-going evaluation is taking place as the teaching sessions continue throughout the year, facilitating the inclusion of additional inter-professional groups from across core specialities. These sessions have been used as a template for the development of further planned IPE with a more varied range of paediatric clinical cases and presentations. These will continue to build on the transferable knowledge and skills that increase competence and confidence in caring for the sick child whilst developing a more collaborative practice-ready workforce.

Acute Pancreatitis Following a Lower Extremity Angioplasty

Introduction: Acute pancreatitis affects a significant population globally. Usual etiologies are gallstones, alcohol, hypertriglyceridemia, medications;less frequent are trauma, hypercalcemia, infections, toxins, ischemia, anatomic anomalies, vasculitis, and idiopathic. Pancreatitis post coronary intervention is an uncommon cause with only 19 published cases in the last two decades. Being cognizant of this etiology is important given the increasing number of patients undergoing angiography. Case Description/Methods: An 81-year-old female with hypertension, diabetes, peripheral arterial disease, prior cholecystectomy underwent left lower extremity angioplasty at an outside center. Within a few hours, she started having severe epigastric pain radiating to her back, nausea, vomiting and loose bloody stool. She presented to the emergency department 24 hours after symptom onset. Epigastric tenderness was present on exam. Labs revealed leukocytosis (24,450/muL), elevated lipase (1410 U/L), elevated creatinine (1.3 mg/dL), lactate (3.1 mmol/L), calcium 9.4 mg/dL and triglycerides 161 mg/dL. Incidentally, found to be positive for COVID-19. Normal common bile duct diameter seen on sonogram. CT angiogram of the abdomen/pelvis showed acute pancreatitis, duodenal and central small bowel enteritis (Figure). She was not on any medications known to cause pancreatitis and denied alcohol use. Patient improved with analgesics and intravenous fluids. She had no recurrence of bloody stools and hemoglobin remained stable. On day 4, she was able to tolerate a regular diet, and leukocyte count and creatinine normalized. Patient did not have any COVID respiratory symptoms, and was discharged. Discussion(s): Given the temporal association to angioplasty and no other identifiable cause, acute pancreatitis was presumed to be due to the contrast used during angioplasty. Other possibilities included cholesterol embolism but no peripheral signs of cholesterol embolism were seen. Patient was an asymptomatic COVID-19 case. Although, there are case series of pancreatitis due to COVID, those were found in very sick symptomatic patients. On review of literature, cholesterol embolism was identified as a definite cause only on autopsy or laparotomy (Table). Other possible mechanisms are: high viscosity of the contrast media leading to ischemia and necrosis, contrast causing NF-kB activation followed by epithelial damage, and vasospasm. Pancreatitis after coronary angiography is rare, nonetheless, an important differential especially if there is a temporal relationship.

A Medical Device Information Data Sheet (MDIDS) to Support the Interoperability of Externally Controllable Infusion Pumps for Tele-Critical Care1

Problem and Motivation. Medical device remote control technologies can enable remote experts to contribute to patient care during tele-critical care during public health emergencies like COVID-19 to address the shortage of local clinical expertise. The benefit of such technologies may be further amplified if one remote-control application can operate multiple interoperable medical devices (e.g. multiple types of ventilators or IV pumps) to support the typical diversity of deployed medical devices in one institution. However, due to the variation in capabilities of different makes/models of the same device type, this unified remote control capability requires the standardization of the data interfaces of similar devices to provide sufficient information about these devices to enable safe remote control. Method(s): Medical Device Interface Data Sheets (MDIDS) [1] can provide a useful tool for documenting current and future device interface requirements and capabilities. We examined several clinical use scenarios where externally controllable infusion pumps are used to support tele-critical care, based on which we generalized an MDIDS for remotely controllable infusion pumps. To validate this generic MDIDS, we cross-checked it with the capabilities of several externally controllable infusion pumps: the NeuroWave Accupump, Eitan Medical Sapphire, and the BD Alaris GH. Result(s): During the development of the generic remotely controllerable infusion pump MDIDS, we were able to identify the common and specific data elements that different infusion pumps need to provide at their data interfaces, considering the great diversity in these devices related to infusion mechanism, infusion programming methods, device alarms and alerts, and system settings. The resulting MDIDS includes over 100 data elements, many of which are essential for safety, including those common across different pump types (e.g., maximum settable infusion rate, occlusion alarm) and those specific to certain pump types (e.g., syringe size for syringe pumps). We developed the generic MDIDS as the theoretical basis and developed an application in our OpenICE open-source interoperability research platform [2] to remotely control the above three infusion pumps either via serial communication (representing controlling the infusion pump at a distance limited by a physical wired connection inside or outside the patient room) or across the Internet using the web extension service of OpenICE (representing situations where remote experts have no physical access to the patient). Conclusion. MDIDS for externally controllable medical devices can provide a solid basis to improve the safety and interoperability of medical device remote control technologies in the tele-critical care context. They can also benefit the research, development, and testing of physiological closed-loop control systems. We applied the MDIDS methodology to infusion pumps and ventilators to support the integration of these devices to the U.S. Army Telemedicine & Advanced Technology Research Center (TATRC) National Emergency Tele-Critical Care System.

Initiating Home Parenteral Nutrition Therapy in a Patient at High Risk of Refeeding Syndrome After COVID-19 Infection

Background: An emerging finding about COVID-19 is its effect on nutrition and weight loss. The COVID-19 symptoms of fatigue, altered taste or smell, and lack of appetite are well known. But COVID-19 may have a more profound effect on clinical nutrition status. Two recent studies have identified that approximately one-third of ambulatory COVID-19 patients are at risk of experiencing weight loss >= 5% (Anker, et al;di Filippo, et al). The case study presented here discusses home start total parenteral nutrition (TPN) in a patient recently diagnosed with COVID-19 at high risk for refeeding syndrome. Method(s): N/A Results: Case Study: A 92-year-old patient was diagnosed with COVID-19 on June 8, 2022. Over the next week, she was hospitalized twice to manage symptoms of acute mental status changes, lethargy, aphasia, hypotension, and loss of appetite. The patient received nirmatrelvir/ritonavir, remdesivir, and bebtelovimab to treat COVID-19 at different times between June 9, 2022, and June 18, 2022. She remained COVID positive and continued to deteriorate clinically. On June 20, 2022, the patient began receiving 24/7 homecare, including intravenous (IV) fluids of dextrose 5% in normal saline (D5NS) 1000 mL daily for three days. She continued to experience loss of appetite and had no bowel movement for 3 days. On June 23, 2022, she was referred to this specialty infusion provider to initiate TPN therapy in the home setting. The patient's BMI was 18.2 kg/m2. Lab results revealed potassium 3.0 mmol/L, phosphate 1.6 mg/dL, and magnesium 1.6 mg/dL. High risk of refeeding syndrome was identified by the level of hypophosphatemia and hypokalemia. The specialty infusion provider's registered dietitian recommended to discontinue D5NS and begin NS with added potassium, phosphate, and magnesium. Thiamine 200mg daily was added to prevent Wernicke's encephalopathy. The patient's clinical status and lab values were monitored closely each day until her electrolyte levels stabilized (Table 1). Home TPN therapy was initiated on June 28, 2022, with <10% dextrose and 50% calorie requirement with 85% protein and 1.0 g/kg lipids. Three-day calorie count and nutrition education were performed four days post TPN initiation. Oral intake met only 25% of estimated needs. Over several days, theTPN formula was gradually increased to goal calories and the infusion cycle was slowly decreased. The following week, the patient's oral intake improved to 60%-75% of estimated needs. Her constipation resolved, and she showed improvement in functional status and mobility. Her appetite drastically improved when the TPN was cycled. Another three-day calorie count was performed when TPN calories reached goals. Oral intake demonstrated 100% estimated calorie and protein needs. TPN therapy was ultimately discontinued on July 14, 2022. As of September 30, 2022, the patient has stabilized at her pre-COVID weight of 45 kg with full recovery of appetite, function, and cognition. Discussion(s): The ASPEN Consensus Recommendations for Refeeding Syndrome (da Silva, et al) describe the repletion of electrolyte levels before introducing calories to prevent end-organ damage associated with refeeding syndrome (respiratory muscle dysfunction, decreased cardiac contractility, cardiac arrhythmias, and encephalopathy). Conclusion(s): This case study highlights the successful initiation of home TPN therapy in a patient at high risk of refeeding syndrome post COVID-19 infection. Although home start TPN and the risk of refeeding syndrome are not new concepts, they must be considered in the setting of COVID-19. Given the effects COVID-19 has on taste, smell, and appetite and the recent finding that one-third of patients with COVID infection may experience weight loss of >= 5%, nutrition support and patient education are vital components of overall patient care.

Out-Patient Antimicrobial Therapy Unit in Universiti Malaya: The Experience of a Single Tertiary Centre in the Klang Valley

Intro: The Out-Patient Parenteral Antimicrobial Therapy (OPAT) is a form of Antimicrobial Stewardship that is now widely-practise throughout the world. However, in Malaysia, this has just only begun to take root and the OPAT in Universiti Malaya (UM) has only just begin operating on 2 August, 2018. The OPAT in Universiti Malaya has been operating for 4 years and is a collaboration between the General Medical Unit and the Infectious Control Unit. Method(s): This was a longitudinal study of all the patients that has been admitted to the OPAT since the start of the service. For each patient the starting and ending date in OPAT, anitbiotic used, the diagnosis, the referring unit, and any problems were recorded. Finding(s): The total patient-days of antibiotics served in the OPAT was 4978, with a mean duration of 66.37 days per patient and a median of 31 days. The majority of cases was referred from the medical department with 41 cases (54.67%) followed by Surgery with 22 cases (29.33%). Ertapenem was the most common antimicrobial served with 39 patients on it (52%) and ceftriaxone was second with 8 patients served (10.67%). All antibiotics have been agreed upon by the Infectious Disease Unit. In our study, 2 patients in OPAT has died but the rest none of them were admitted for hospital associated infection. Discussion(s): We found that OPAT on average save at least ten beds per day in the hospital. The patients are happy because they do not need to be warded in hospital to receive their antimicrobials. However, we faced limitations in recruitment of patients to the OPAT during the COVID-19 pandemic, staff shortages, the lack of infusion pumps for serving multidose antimicrobials, and bureacratic red-tape. Conclusion(s): OPAT was useful in reducing bed occupancy rate and hospital associated infection. Patients also are happy with the service.Copyright © 2023

Time requirements for perioperative glucose management using fully closed-loop versus standard insulin therapy: A proof-of-concept time-motion study.

AIMS: To compare the time required for perioperative glucose management using fully automated closed-loop versus standard insulin therapy. METHODS: We performed a time-motion study to quantify the time requirements for perioperative glucose management with fully closed-loop (FCL) and standard insulin therapy applied to theoretical scenarios. Following an analysis of workflows in different periods of perioperative care in elective surgery patients receiving FCL or standard insulin therapy upon hospital admission (pre- and intra-operatively, at the intermediate care unit and general wards), the time of process-specific tasks was measured by shadowing hospital staff. Each task was measured 20 times and its average duration in combination with its frequency according to guidelines was used to calculate the cumulative staff time required for blood glucose management. Cumulative time was calculated for theoretical scenarios consisting of elective minor and major abdominal surgeries (pancreatic surgery and sleeve gastrectomy, respectively) to account for the different care settings and lengths of stay. RESULTS: The FCL insulin therapy reduced the time required for perioperative glucose management compared to standard insulin therapy, across all assessed care periods and for both perioperative pathways (range 2.1-4.5). For a major abdominal surgery, total time required was 248.5 min using FCL versus 753.9 min using standard insulin therapy. For a minor abdominal surgery, total time required was 68.6 min and 133.2 min for FCL and standard insulin therapy, respectively. CONCLUSIONS: The use of fully automated closed-loop insulin delivery for inpatient glucose management has the potential to alleviate the workload of diabetes management in an environment with adequately trained staff.

The First Reported Case of Lorlatinib-Associated Diabetic Ketoacidosis

Introduction: Lorlatinib is a third-generation tyrosine kinase inhibitor that inhibits anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1). Although 2-10% of patients with non-small cell lung cancer developed hyperglycemia in phase 2 and 3 studies of lorlatinib, only one case has subsequently reported hyperglycemia >500 mg/dL, and no cases of diabetic ketoacidosis (DKA) have been previously reported. Phase 1 trials in neuroblastoma are ongoing. Case Description: A 34-year-old woman with ALK-mutated paraspinal neuroblastoma presented with DKA 14 months after initiation of lorlatinib. Prior to starting lorlatinib, her hemoglobin A1c had been 5.0% (n: < 5.7%). After 12 months of therapy, her A1c increased to 7.8%, prompting the initiation of metformin 500 mg daily. However, two months later she was admitted for DKA with a blood glucose of 591 mg/dL (n: 65-99 mg/dL), CO2 17 mmol/L (n: 20-30 mmol/L), anion gap 18 (n: 8-12), moderate serum ketones, and 3+ ketonuria. Her A1c was 14.8%, C-peptide was 1.2 ng/mL (n: 1.1-4.3 ng/mL), and her glutamic acid decarboxylase-65 and islet antigen-2 autoantibodies were negative. She was also found to be incidentally positive for COVID-19 but was asymptomatic without any oxygen requirement. The patient's DKA was successfully treated with IV insulin infusion, and she was discharged after 3 days with insulin glargine 27 units twice daily and insulin aspart 16 units with meals. One month later, her hemoglobin A1c had improved to 9.4%, and the patient's oncologist discontinued lorlatinib due to sustained remission of her neuroblastoma and her complication of DKA. After stopping lorlatinib, her blood glucose rapidly improved, and she self-discontinued all her insulin in the following 3 weeks. One month later, she was seen in endocrine clinic only taking metformin 500 mg twice daily with fasting and post-prandial blood glucose ranging 86-107 mg/dL. Discussion(s): This is the first reported case of DKA associated with lorlatinib. This case highlights the importance of close glucose monitoring and the risk of severe hyperglycemia and DKA while on lorlatinib therapy. Discontinuation of lorlatinib results in rapid improvement of glycemic control, and glucose-lowering treatments should be promptly deescalated to avoid hypoglycemia.Copyright © 2023

The Complexities of Managing Hypertriglyceridemia-Induced Pancreatitis in a Critically-Ill COVID-19 Patient

Introduction: Hypertriglyceridemia-induced pancreatitis (HTP) is a variant of pancreatitis requiring unique management. The complications of COVID-19 and its treatments can make HTP therapy more nuanced. This case describes a patient who presented in diabetic ketoacidosis (DKA) with HTP, and COVID-19. The patient developed renal and respiratory failure, necessitating hemodialysis (HD) and extracorporeal membrane oxygenation (ECMO), complicating an otherwise straightforward medical management plan. Case Description: A morbidly obese (BMI 38.9 kg/m2) 43-year-old male presented to an outside hospital with abdominal pain, and vomiting, and was found to have HTP with triglycerides (TG) >2000 mg/dL (<149 mg/dL) and presumed new-onset type 2 Diabetes (HbA1c 10.9%) with DKA. Treatment with fluids, intravenous (IV) insulin infusion and plasmapheresis were initiated. He developed hypoxia after receiving over 17 liters of fluids and was intubated, subsequently developing renal failure and was transferred to our tertiary center for HD and ECMO. On admission, he tested positive for COVID-19, rhabdomyolysis [creatinine kinase 5600 U/L (30-200 U/L)], HTP [TG 783 mg/dL (<149 mg/dL), lipase 461 U/l (7-60 U/L)], glucose 269 mg/dL (not in DKA), transaminitis [AST 184 U/L (4-40 U/L), ALT 61 U/L (4-41 U/L)] and renal failure (GFR 10 ml/min/1.73m2). IV insulin infusion was initiated for hyperglycemia worsened by COVID-19 dexamethasone treatment. Plasmapheresis was performed twice with minimal effect at maintaining a low TG. Fenofibrate was not initiated due to renal failure;Lovaza could not be given via oral gastric tube;Atorvastatin was attempted once rhabdomyolysis resolved, with subsequent worsening of liver function tests. Heparin infusion was initiated for deep vein thrombosis treatment and HTP but was stopped after development of heparin induced thrombocytopenia. The patient developed worsening hypoglycemia requiring cessation of IV insulin, hypotension requiring maximum pressor support, and worsening sepsis leading to his death. Discussion(s): This case illustrates the challenges of managing a patient with HTP and COVID-19. It demonstrates how a normally straightforward treatment algorithm can become increasingly complex when factoring the patient's comorbid conditions. The case highlights the importance of knowing both treatment indications and contraindications for HTP. In this case, HTP may have been the initial diagnosis, straightforward for most endocrinologists, but its treatments and comorbid conditions ultimately made the landscape more challenging, limiting effective management and ultimately leading to this patient's demise.Copyright © 2023

L-Ornithine-L-Aspartate and Intermittent Renal Replacement Therapy in Fulminant Hepatitis A: A Case Report

Hepatitis A is a common viral infection worldwide that is transmitted via the fecal-oral route. Since the introduction of an efficient vaccine, the incidence of infection has decreased but the number of cases has risen due to widespread community outbreaks among unimmunized individuals. Classic symptoms include fever, malaise, dark urine, and jaundice, and are more common in older children and adults. People are often most infectious 14 days prior to and 7 days following the onset of jaundice. We will discuss the case of a young male patient, diagnosed with acute hepatitis A, leading to fulminant hepatitis refractory to conventional therapy and the development of subsequent kidney injury. The medical treatment through the course of hospitalization was challenging and included the use of L-ornithine-L-aspartate and prolonged intermittent hemodialysis, leading to a remarkable outcome. Hepatitis A is usually self-limited and vaccine-preventable;supportive care is often sufficient for treatment, and chronic infection or chronic liver disease rarely develops. However, fulminant hepatitis, although rare, can be very challenging to manage as in the case of our patient.Copyright © 2023 The Author(s).

Performance of a Computerized Insulin Infusion Protocol in 359 Critically Ill Patients with COVID-19

Objective: People with diabetes and uncontrolled hyperglycemia are at high risk of COVID-19 complications and as such, many patients admitted to the ICU with COVID-19 have diabetes or stress hyperglycemia. It is suggested that quick and adequate control of hyperglycemia without increasing the risk of hypoglycemia is imperative to improve outcomes in these patients. Control of wide fluctuations of glycemic variances in these patients may often require modifications of existing strategies of glycemic management. Use of a computerized insulin infusion protocol (CIIP) in these settings could be largely beneficial in getting early and sustained glycemic control. We report our experience with the Lalani Insulin Infusion Protocol (LIIP), a novel CIIP with dynamic and adaptive glycemic targets in accordance with the patient's glycemic state, in critically ill COVID-19 patients with hyperglycemia treated with IV insulin. Method(s): We conducted a retrospective analysis of 359 critically-ill COVID-19 patients in whom LIIP was used (8/18/2020 to 08/31/2022) at six HonorHealth Hospitals in the Phoenix metropolitan area. Primary endpoints of the analysis included Time to Euglycemia (min), % of time in euglycemia (70-180 mg/dl), % of time in hyperglycemia (>180 mg/dl), and % of time in hypoglycemia (<70 mg/dl). We also report the average length of stay (ALOS) in the hospital and ICU as well as the discharge dispositions of these patients. Result(s): Of the 359 critically ill COVID-19 patients who received IV insulin directed by LIIP, 167 patients had diabetes, 266 patients were treated with steroids, 226 patients had compromised renal function (eGFR< 60), 40 patients had sepsis, and 5 patients had cardiovascular comorbidities. The following glucometrics were observed: average Time to Euglycemia from baseline glucose values was 278 minutes, average % time in euglycemia was 83.01%, average % time in hyperglycemia was 16.77%, and average % time in hypoglycemia was 0.22%. Of the 359 patients, there were 166 deaths (46.2%), 91 patients were discharged to home (25.4%), and 102 patients were discharged to an interim facility (28.4%). The hospital ALOS was 15.02 days and ICU ALOS was 9.50 days. Discussion/Conclusion: For HonorHealth hospitals, LIIP was a safe and effective method of quickly achieving and maintaining euglycemia in critically ill patients with COVID-19, while maintaining low hypoglycemia incidence. Herein the patients reported had varying degrees of comorbidities and treatments, including steroids and vasopressors;however, no modifications in glycemic management strategy or nursing workflow were necessary during the use of LIIP due to its adaptive formula which individualizes IV insulin rates for each patient.Copyright © 2023

WORKING PRINCIPLE AND INTELLIGENCE OF SMART INFUSION PUMP

There is a tremendous demand on the critical care resources due to the extensive spread of the ongoing coronavirus pandemic and the large number of patients requiring critical care. The efficacy of a device directly influences how long a patient lives since patients are often receiving critical care. Smart infusion pump is a medical device that can drip fluids into the patient's body. This device is considered as one of the most safety-critical medical devices due to the way it functions and the risks it presents. The main objective of this work is to develop an affordable infusion pump usin g embedded technology. The main tactic is to develop equipment that can identify air bubbles in infusion pump tubing since even a little one might obstruct blood flow and result in mortality. This method may provide consumers an accurate result, making it the greatest method for identifying bubbles and saving lives.

Clinical Experience of Using Telemedicine for the Management of Patients Using Continuous Subcutaneous Insulin Infusion in a Highly Complex Latin American Hospital.

INTRODUCTION: Continuous subcutaneous insulin infusion (CSII) has emerged as a potential solution for diabetes management during the pandemic, as it reduces the need for in-person visits and allows for remote monitoring of patients. Telemedicine has also become increasingly important in the management of diabetes during the pandemic, as it allows healthcare providers to provide remote consultations and support. Here, we discuss the implications of this approach for diabetes management beyond the pandemic, including the potential for increased access to care and improved patient outcomes. METHODS: We performed a longitudinal observational study between 1 March 2020 and 31 December 2020 to evaluate glycemic parameters in diabetic patients with CSII in a telehealth service. Glycemic parameters were time in range (TIR), time above range, time below range, mean daily glucose, glucose management indicator (GMI), and glycemic variability control. RESULTS: A total of 36 patients were included in the study, with 29 having type 1 diabetes and 6 having type 2 diabetes. The study found that the proportion of patients achieving target glucose variability and GMI remained unchanged during follow-up. However, in patients with type 2 diabetes, the time in target range increased from 70% to 80%, and the time in hyperglycemia decreased from 2% to 0%. CONCLUSIONS: The results of this study suggest that telemedicine is a strategy for maintaining glycemic control in patients using CSII. However, the lack of access to the internet and adequate telemonitoring devices make it difficult to use on a large scale in emerging countries like ours.

A Phase II, Open-Label Study of an Accelerated Infusion Rate of Daratumumab in Patients With Relapsed and Refractory Multiple Myeloma.

INTRODUCTION/BACKGROUND: Daratumumab is an anti-CD38 monoclonal antibody initially approved as a single agent for the treatment of relapsed and refractory multiple myeloma. The infusion-related reactions (IRRs) commonly seen with intravenous daratumumab have been managed by prolonging the first infusion, temporarily stopping/slowing the rate if reactions occur and using adequate pre- and post-infusion medications. Several retrospective studies have evaluated shorter infusions after ≥ 2 prior doses administered at the standard rates. Although the shorter infusions were well-tolerated, patients in these reports were given heterogeneous daratumumab regimens and had often already received multiple doses at the longer standard rates. PATIENTS AND METHODS: CMRG-009 is a prospective study designed to demonstrate the safety of accelerated daratumumab infusions commencing with the second dose. After an initial dose on Cycle 1 Day consisting of 8 mg/kg over 4 hours, all subsequent doses were given over 90 minutes. RESULTS: No grade 3 IRRs were observed with the 90-minutes infusions. Both the safety profile and anti-myeloma effects were otherwise similar to those observed with other single agent daratumumab studies using longer infusion times. CONCLUSION: This is the first formal prospective trial using infusion times shorter than the standard schedule directly after an initial 4-hours dose. This rapid infusion protocol has resulted in more efficient resource utilization and has become the standard protocol for the use in all intravenous daratumumab regimens in Canada. This approach has been particularly helpful in shortening chair time during the COVID-19 pandemic and providing a useful alternative in jurisdictions without access to subcutaneous daratumumab.

Successful Treatment of Subclavian Artery Thrombosis by Catheter-Based Thrombus Aspiration and Thrombolytic Therapy: A Case Report

Clinical Information Patient Initials or Identifier Number: BP4****/22 Relevant Clinical History and Physical Exam: A 55 Y / Female C/C : Pain, numbness, cold sensation & weakness of left upper limb for 2 hours. Risk Factor : Hypertension, diabetes mellitus O/E : Pale, cold and absent of radial, ulnar, brachial pulse of left upper limb. Muscle power 3/5 left side. So2 86%, BP undetectable. Right upper limb were normal. BP 160/90 mm of hg, pules : 112 b/min, RR : 26/min. Body Temperature 37.5 C [Formula presented] [Formula presented] Relevant Test Results Prior to Catheterization: CBC : WBC 7450, HB % 10.8 g/dl, ESR 20mm in 1st hour, Platelets : 262000, SARS Cov2 Antigen : Negative PT 14.3 sec, INR : 1.07 APTT : 32.4 sec. blood group: O positive Serum Creatinine : 1.1 mg/dl Plasma glucose 9.7 mmmol/l HIV Ab : Negative HBs Ag : Negative Anti-HCV : Negative Urine R/E : Normal lipid profile : Cholesterol 280mg/dl Vascular duplex ultrasound of left upper limb : A dilated echogenic thrombus had blocked the left subclaviav artery lumen. Relevant Catheterization Findings: Conventional angiography with the lowest amount of contrast agent through the right femoral artery, revealed that left subclavian artery thrombosis with total occlusion distal to Left internal mammary artery. [Formula presented] [Formula presented] [Formula presented] Interventional Management Procedural Step: A5Fr MPA catheter with side holes was negotiated through a right femoral sheath and was placed in the left subclavian artery. Initially thrombus aspiration was done with Eliminate aspiration catheter (TERUMO) with no success. Then suction was done with the MPA catheter itself with partial removal of thrombus. Then a 5Fr Pigtail catheter was placed inside the thrombus and kept in situ. For residual thrombus 250,000u of Inj. Streptokinase as a thrombolytic drug was given through the Pigtail catheter as bolus over 30 min. The maintenance dose 100,000 u per hour was given over 24 hours through the Pigtail catheter via infusion pump. After 24 hours of thrombolytic therapy, her pain was reduced, the left hand became slightly warm, and distal pulses were feebly palpable. Moreover, the skin colour returned to near normal with improvement of pallor. Bleeding was well controlled at the catheter site. Doppler sounds revealed partial improvement of arterial flow. After evaluation of partial improvement, a low dose 1000 iu per hour of heparin (UFH)was infused intravenously for 24 hours. After 48 hours, repeat angiography via the inserted catheter at the site did not reveal any atherosclerotic plaque and confirm the thrombosis-dissolution. The latter practice demonstrated a good blood flowto the left upper distal limb leaving a little thrombus in the superficial palmer arch. [Formula presented] [Formula presented] [Formula presented] Conclusion(s): Catheter-based thrombus aspiration and thrombolytic therapy is primarily reserved for patients with acute viable limb ischemia. As observed in the presented case, thrombus aspiration and thrombolytic therapy is recommended to be considered as an alternative therapeutic method for patients with arterial thrombosis due to the rapid response, shorter treatment time and lower cost, compared to common and sometimes unsuccessful therapies.Copyright © 2023

Idiopathic anomalous congenital band causing small intestinal obstruction in a 5-month-old dog

A 5-month-old, intact male, yellow Labrador retriever was presented with a 24-hour history of anorexia and vomiting. Abdominal imaging revealed the presence of a mechanical obstruction in the jejunum and peritoneal effusion. Cytologic evaluation and culture of the effusion prior to surgery identified a suppurative exudate with bacteria consistent with septic peritonitis and suspected to be related to the intestinal lesion. An exploratory laparotomy was performed, and a segment of jejunum was circumferentially severely constricted by an off-white, fibrous band of tissue. Resection and anastomosis of the strangulated segment of jejunum and excision of the constricting band provided resolution of the clinical signs. The dog made a complete recovery. Histologic evaluation revealed the band to be composed of fibrovascular and smooth muscle tissue, consistent with an idiopathic anomalous congenital band. No other gastrointestinal lesions were observed, either grossly at surgery or histologically in the resected segment of intestine. To our knowledge, a similar structure has not been reported in the veterinary literature.Copyright © 2022 Canadian Veterinary Medical Association. All rights reserved.

Year 2022 in Review - Intensive care medicine - Cardiovascular and general issues.

In 2022, intensive medicine all around the world gradually began to return to standard tracks, although we could still observe the effects of the pandemic waves of the disease COVID-19. In the literature, we could note the publication of research studies of "violently terminated" pandemics and new works. This review article presents a selection of the most interesting published articles in general intensive care medicine and those focusing on cardiovascular issues.Copyright © 2022, Czech Medical Association J.E.

Positive Impact of Home ERT for Mucopolysaccharidoses and Pompe Disease: The Lesson Learnt from the COVID-19 Pandemic.

OBJECTIVE: Patients with Lysosomal disorders (LSDs) are treated with regular infusions of enzyme replacement therapy (ERT). During the COVID-19 pandemic, home treatment was permitted. This study aimed at monitoring the patients' compliance with home therapy and its effects on physical, psychological, and relational issues. Moreover, we also tested the possible impact of home therapy on familial relationships and contacts with the referral hospital. MATERIALS AND METHODS: Thirteen patients with Pompe disease (N = 8) and MPS (N = 5) were tested through an online questionnaire designed to assess their level of appreciation and satisfaction with home therapy and their feelings about the referral centre and psychological support provided. RESULTS: Most of the patients (84%) stressed the positive impact of home therapy. All patients described a significant reduction in stressful conditions associated with the need to attend the hospital every week or two. CONCLUSIONS: Home ERT leads to a clear improvement in "daily life skills", as represented in our by sample by positive feelings, better emotional self-control, and an increased ability to understand the feelings of relatives. Our data underline the paramount positive effect home ERT has on both patients and their families.

Novel Coronavirus is the Only Virus Causing Childhood Invasive Diarrhea: A Case Series

Introduction: Typical manifestations of Coronavirus disease 2019 (COVID-19) include respiratory involvement. Gastrointestinal (GI) symptoms have also been reported as early clinical manifestations. The GI involvement can represent with diarrhea, vomiting, and abdominal pain. The present research aimed to identify dysentery as one of the signs of GI involvement in the novel coronavirus infection in children. Case Presentation: We report twelve patients with COVID-19 and dysentery. All these children had positive reverse transcriptionpolymerase chain reaction (RT-PCR) results. None had underlying illnesses or recent travel history. However, all children had contact with a first-degree relative affected by non-digestive COVID-19. In three patients, obvious dysentery was observed, and in the rest, red and white blood cells were evident in the stool exam. Stool exams were negative for bacterial infections, parasites, and the toxin of Clostridium difficile. Abdominal ultrasonography and echocardiographic evaluations to rule out multisystem inflammatory syndrome in children were normal. Supportive treatment, such as zinc supplementation and probiotics, was prescribed. They also received intravenous fluid therapy based on their dehydration percentage. In the end, they were discharged in good general condition without any complications. No GI complications were found in the follow-up series. Conclusion(s): Dysentery in children can be one of the GI manifestations of COVID-19, which is usually self-limiting. It does not require invasive diagnostic measures and antiviral treatments. This symptom is in contrast to other viral infections of the GI tract.Copyright © 2022, Author(s).

COVID 19 Induced Hyperglycaemic Complications

Background: COVID 19 has two-way interaction with Type II Diabetes Mellitus. First, patient with DM are more prone for developing severe COVID 19. Second, moderate to severe COVID 19 can present with new onset DM or may lead to hyperglycaemia and hyperglycaemic complications in Type II DM patients. In this report we present 4 cases of COVID 19 associated Hyperglycaemic Complication (3 with Diabetic Ketoacidosis and 1 with Hyperglycaemic hyperosmolar state). Method(s): Case Series of patients admitted to Thumbay Hospital, Ajman. Result(s): We report 4 cases of COVID 19 patients who presented to us with hyperglycaemic complications. There of them had features of Diabetic Ketoacidosis and one had Hyperglycaemic hyperosmolar state. All were treated with IV Insulin infusion and IV Fluids. COVID 19 infection was managed as per MOH protocol. All patients recovered well and were discharged in stable condition. Discussion(s): COVID 19 is associated with new onset DM or may lead to hyperglycaemic complications in patients with Type II DM. There are three pathophysiological processes which may be responsible for this finding. One, SARS-CoV-2 virus is known to enter the body through angiotensin-converting enzyme (ACE) II receptors in the pulmonary pneumocytes leading to infection and inflammation. Similar ACE-II receptors are also expressed in key metabolic organs and tissues, including pancreatic beta cells, adipose tissue, the small intestine, and the kidneys. Direct infection of pancreatic beta-cells with SARS-CoV-2 virus with beta-cell cell injury is likely the underlying mechanism for development of new onset diabetes and hyperglycaemia in existing diabetic patients. Such direct beta cell infection can cause hyperglycaemic complications in asymptomatic or mild COVID 19 as well. Two, moderate to severe COVID 19 is associated with hyperinflammatory immune response leading to marked rise in inflammatory mediators such as C-reactive protein and ferritin. Such hyperinflammatory response can also lead to hyperglyacemia in patients with diabetes mellitus. Three, corticosteroids are mainstay treatment of patients with moderate to severe COVID 19 and would definitely contribute to worsening of hyperglycaemia in these patients. Our patients presented to us with hyperglycaemic complications before initiation of any treatment. It is likely that such a situation would be due to direct infection and destruction of beta cells with SARS-CoV-2 virus infection. Conclusion(s): Type II Diabetes Mellitus patients are high risk of developing hyperglycaemic complications due to COVID 19. This can lead to increased morbidity and mortality. Patients with Type II DM should seek medical attention even if they have mild to asymptomatic COVID 19 to monitor for hyperglycaemic complication which can develop irrespective of severity of stage of illness.
