A case series is presented of five overweight or obese patients with confirmed coronavirus disease 2019 (COVID-19) in South Miami, Florida, United States. A multitude of coagulation parameters was suggestive of a hypercoagulable state among the hospitalized COVID-19 patients. This article reports various manifestations of hypercoagulable states in overweight and obese patients, such as overt bleeding consistent with disseminated intravascular coagulation, venous thromboembolism, gastrointestinal bleeding as well as retroperitoneal hematoma. All of the required admission to the intensive care unit and subsequently patients died. The characteristics of COVID-19-associated coagulopathy are atypical and warrant a further understanding of the pathophysiology to improve clinical outcomes, specifically in overweight or obese patients.

Severe Acute Motor Axonal Neuropathy Associated with Influenza-A (H1N1) Infection and Prolonged Respiratory Failure – A Case Report
Acute Motor Axonal Neuropathy (AMAN) is an immune-mediated disorder of the peripheral nervous system, part of the spectrum of the Guillain-Barre syndrome (GBS). An infectious event most often triggers it reported a few weeks before the onset. The reported case is of a 56 years-old woman who developed acute motor axonal neuropathy three weeks after respiratory infection with influenza A virus subtype H1N1. Despite early treatment with plasmapheresis and intravenous immunoglobulins, the patient remained tetraplegic, mechanically ventilated for five months, with repetitive unsuccessful weaning trails. The probable cause was considered to be phrenic nerve palsy in the context of acute motor axonal neuropathy. This case highlights that acute motor axonal neuropathy is a severe and life-threatening form of Guillain-Barre syndrome associated with significant mortality and morbidity. Neurological and physical recovery strongly depend on the inter-professional effort in an intensive care unit and neurology professionals.
Shock Due to an Obstructed Endotracheal Tube
Endotracheal tube obstruction by a mucus plug causing a ball-valve effect is a rare but significant complication. The inability to pass a suction catheter through the endotracheal tube with high peak and plateau pressure differences are classical features of an endotracheal tube obstruction. A case is described of endotracheal tube obstruction from a mucus plug that compounded severe respiratory acidosis and hypotension in a patient who simultaneously had abdominal compartment syndrome. The mucus plug was not identified until a bronchoscopic assessment of the airway was performed. Due to the absence of classical signs, the delayed identification of the obstructing mucus plug exacerbated diagnostic confusion. It resulted in various treatments being trialed whilst the patient continued to deteriorate from the evasive offending culprit. We suggest that earlier and more routine use of bronchoscopy should be employed in an intensive care unit, especially as a definitive way to rule out endotracheal obstruction.
Hypothalamic-pituitary axis disorder – “the puppet master” of multiple organ dysfunction in brain-dead patients
One of the most revolutionary discoveries of modern medicine was organ transplantation, as it brought hope and healing in cases that seemed incurable. Best outcomes in organ transplantation are related to a rigorous tissue typing and an appropriate immunosuppressant therapy that allowed a longer survival rate for recipients [1]. The management of the potential brain-dead donor is a complex one that involves several well-defined stages: early identification of potential donors, brain death determination, maintaining vital functions, and graft transplantation.
Brain death determination is synonymous with irreversible anatomical and functional injury to the entire brain and brainstem. This process involves a major alteration of the hemodynamic and hormonal homeostasis. Hypothalamic irreversible injury is followed by a profound normothermia dysregulation. The aggressive inflammatory response after brain death occurrence is responsible for capillary leakage and refractory hypotension [2]. Clinical diagnostic tests that assess brain death include brain stem areflexia, apnea, and cerebral unresponsiveness, linked with a known, irreversible cause of coma [3].[More]

The Importance of Iron Administration in Correcting Anaemia after Major Surgery
Introduction: Postoperative anaemia can affect more than 90% of patients undergoing major surgeries. Patients develop an absolute iron deficiency in the face of significant blood loss or preoperative anaemia and major surgery. Studies have shown the negative impact of these factors on transfusion requirements, infections, increased hospitalisation and long-term morbidities.
Aim of the study: The research was performed to determine the correlation between intravenous iron administration in the postoperative period and improved haemoglobin correction trend.
Material and methods: A prospective study was conducted to screen and treat iron deficiency in patients undergoing major surgery associated with significant bleeding. For iron deficiency anaemia screening, in the postoperative period, the following bioumoral parameters were assessed: haemoglobin, serum iron, transferrin saturation (TSAT), and ferritin, direct serum total iron-binding capacity (dTIBC), mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH). In addition, serum glucose, fibrinogen, urea, creatinine and lactate values were also collected.
Results: Twenty-one patients undergoing major surgeries (52,38% were emergency and 47,61% elective interventions) were included in the study. Iron deficiency, as defined by ferritin 100-300 μg/L along with transferrin saturation (TSAT) < 20 %, mean corpuscular volume (MVC) < 92 fL, mean corpuscular haemoglobin (MCH) < 33 g/dL, serum iron < 10 μmol/L and direct serum total iron-binding capacity (dTIBC) > 36 μmol/L, was identified in all cases. To correct the deficit and optimise the haematological status, all patients received intravenous ferric carboxymaltose (500-1000 mg, single dose). Using Quadratic statistical analysis, the trend of haemoglobin correction was found to be a favourable one.
Conclusion: The administration of intravenous ferric carboxymaltose in the postoperative period showed the beneficial effect of this type of intervention on the haemoglobin correction trend in these groups of patients.
Analgosedation: The use of Fentanyl Compared to Hydromorphone
Background: The 2018 Society of Critical Care Medicine guidelines on the “Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU” advocate for protocol-based analgosedation practices. There are limited data available to guide which analgesic to use. This study compares outcomes in patients who received continuous infusions of fentanyl or hydromorphone as sedative agents in the intensive care setting.
Methods: This retrospective cohort study evaluated patients admitted into the medical intensive care unit, the surgical intensive care unit, and the cardiac intensive care unit from April 1, 2017, to August 1, 2018, who were placed on continuous analgesics. Patients were divided according to receipt of fentanyl or hydromorphone as a continuous infusion as a sedative agent. The primary endpoints were ICU length of stay and time on mechanical ventilation.
Results: A total of 177 patients were included in the study; 103 received fentanyl as a continuous infusion, and 74 received hydromorphone as a continuous infusion. Baseline characteristics were similar between groups. Patients in the hydromorphone group had deeper sedation targets. Median ICU length of stay was eight days in the fentanyl group compared to seven days in the hydromorphone group (p = 0.11) and median time on mechanical ventilation was 146.47 hours in the fentanyl group and 122.33 hours in the hydromorphone group (p = 0.31). There were no statistically significant differences in the primary endpoints of ICU length of stay and time on mechanical ventilation between fentanyl and hydromorphone for analgosedation purposes.
Conclusion: No statistically significant differences were found in the primary endpoints studied. Patients in the hydromorphone group required more tracheostomies, restraints, and were more likely to have a higher proportion of Critical Care Pain Observation Tool (CPOT) scores > 2.
Acute Kidney Injury Following Rhabdomyolysis in Critically Ill Patients
Introduction: Rhabdomyolysis, which resulted from the rapid breakdown of damaged skeletal muscle, potentially leads to acute kidney injury.
Aim: To determine the incidence and associated risk of kidney injury following rhabdomyolysis in critically ill patients.
Methods: All critically ill patients admitted from January 2016 to December 2017 were screened. A creatinine kinase level of > 5 times the upper limit of normal (> 1000 U/L) was defined as rhabdomyolysis, and kidney injury was determined based on the Kidney Disease Improving Global Outcome (KDIGO) score. In addition, trauma, prolonged surgery, sepsis, antipsychotic drugs, hyperthermia were included as risk factors for kidney injury.
Results: Out of 1620 admissions, 149 (9.2%) were identified as having rhabdomyolysis and 54 (36.2%) developed kidney injury. Acute kidney injury, by and large, was related to rhabdomyolysis followed a prolonged surgery (18.7%), sepsis (50.0%) or trauma (31.5%). The reduction in the creatinine kinase levels following hydration treatment was statistically significant in the non- kidney injury group (Z= -3.948, p<0.05) compared to the kidney injury group (Z= -0.623, p=0.534). Significantly, odds of developing acute kidney injury were 1.040 (p<0.001) for mean BW >50kg, 1.372(p<0.001) for SOFA Score >2, 5.333 (p<0.001) for sepsis and the multivariate regression analysis showed that SOFA scores >2 (p<0.001), BW >50kg (p=0.016) and sepsis (p<0.05) were independent risk factors. The overall mortality due to rhabdomyolysis was 15.4% (23/149), with significantly higher incidences of mortality in the kidney injury group (35.2%) vs the non- kidney injury (3.5%) [ p<0.001].
Conclusions: One-third of rhabdomyolysis patients developed acute kidney injury with a significantly high mortality rate. Sepsis was a prominent cause of acute kidney injury. Both sepsis and a SOFA score >2 were significant independent risk factors.
The Pathophysiology and Management of Diabetic Ketoacidosis in COVID-19 Patients: A Literature Review
Diabetic individuals are considered a vulnerable population during the COVID-19 Pandemic, and several studies noted worse outcomes, including death, among those who get infected. Diabetic emergencies, such as ketoacidosis (DKA), are common and potentially life-threatening conditions in uncontrolled patients. While the pathophysiological background of the relationship between COVID-19 and DKA is not fully understood, early reports available so far indicate that patients with pre-existing diabetes who get infected with the SARS-CoV 2 virus are at higher risk of DKA. It was also suggested that DKA is a poor prognostic sign for infected patients, these being at higher risk of developing worse forms of COVID-19 disease and having high mortality. Therefore, healthcare personnel dealing with such patients face a considerable challenge, as the correct and safe emergency management of such cases is far from established. This article aimed to conduct a study that reviews the current published data available about patients with DKA and COVID-19.
