BACKGROUND: The use of thromboelastography (TEG) has demonstrated decreased blood product utilization in patients with specific etiologies of major gastrointestinal bleeding (GIB), such as variceal and non-variceal bleeding in cirrhosis patients; however, in a non-cirrhosis patient with GIB, there is far less evidence in the literature. Our retrospective study compares the effect of TEG-guided blood product utilization in patients with major GIB with all etiologies, including cirrhosis, admitted to medical intensive care unit (MICU)...

OBJECTIVE: To determine whether age, mobility level, and change in mobility level across the first 3 physical rehabilitation sessions associate with clinical outcomes of patients who are critically ill. DESIGN: Retrospective, observational cohort study. SETTING: Medical Intensive Care Unit (MICU). PARTICIPANTS: Hospitalized adults (n = 132) who received 3 or more, consecutive rehabilitation sessions in the MICU...

AIMS: Data regarding the treatment of hip osteoarthritis (OA) with collagen-based extracellular bio-scaffolds are lacking. We evaluated the treatment of hip OA with ultrasound guided intraarticular injections of Collagen-based Medical Device (CMD). MATERIAL AND METHODS: Forty-four patients with Kellgren-Lawrence grade (KLG) I or II were selected, and 20/44 randomly selected patients (CMD group), were treated with 2 weekly consecutive ultrasound guided intraarticular injections of CMD (MD-HIP, Guna S...

In this study, sodium alginate (SA) was oxidized with potassium periodate to produce an alginate-based tanning agent. Using OSA as a biodegradable tanning agent and a nano-hydroxyapatite (nano-HAp) low concentration suspension to give flame retardancy to leather, eco-design concepts were applied to establish a chrome-, aldehyde-, and phenol-free tanning process. Micro-DSC, 1 H unilateral nuclear magnetic resonance (NMR), attenuated total reflection mode Fourier transform infrared spectroscopy (FTIR-ATR), and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) were used to investigate the complex matrix collagen-OSA-nano-HAp...

BACKGROUND: We sought to evaluate the long-term effects of COVID-19 on renal function in patients with biopsy-proven kidney diseases. METHODS: A total of 451 patients with biopsy-proven kidney disease and at least 12 months of follow-up subsequent to COVID-19 pandemic onset were included in the study. The primary study endpoint was a composite of a persistent decline of more than 30% in eGFR or ESRD. RESULTS: 23.1% of patients had COVID-19 during a follow-up period of 2...

BACKGROUND: Severe Acute Respiratory Infections (SARI) caused by influenza and other respiratory viruses pose significant global health challenges, and the COVID-19 pandemic has further strained healthcare systems. As the focus shifts from the pandemic to other respiratory infections, assessing the epidemiology and burden of SARI is crucial for healthcare planning and resource allocation. Aim: to understand the impact of the post-pandemic period on the epidemiology of SARI cases, clinical outcomes, and healthcare resource utilization in Tunisia...

BACKGROUND: Rifaximin is frequently administered to critically ill patients with liver disease and hepatic encephalopathy, but patients currently or recently treated with antibiotics were frequently excluded from studies of rifaximin efficacy. Due to overlapping spectrums of activity, combination therapy with broad-spectrum antibiotics and rifaximin may be unnecessary. A pharmacist-driven protocol was piloted to reduce potentially overlapping therapy in critically ill patients with liver disease...

Objective Infections leading to severe sepsis and septic shock are among the top five causes requiring admission to the intensive care unit (ICU). Up to 40% of ICU admissions contain a sepsis diagnosis. Without a clear marker to diagnose and manage sepsis, procalcitonin has been extensively studied for its usefulness in the management of bacterial infections. These studies, however, have been focused toward how it can be used to help guide when antibiotics should be initiated and de-escalated...

Background: Evidence suggests that goal anti-Xa levels are achieved in only 33% of critically ill patients receiving standard prophylactic enoxaparin dosing. There has been limited focus on the potential suboptimal anticoagulation effect on medical intensive care unit (MICU) patients receiving therapeutic enoxaparin dosing for venous thromboembolism (VTE). Methods: MICU patients receiving enoxaparin 1 mg/kg twice daily or 1.5 mg/kg daily for VTE treatment in a 350-bed community teaching hospital between 2013 and 2019 with at least one peak anti-Xa level measured were included...

BACKGROUND: Diagnosis of invasive candidiasis (IC) is limited by insensitivity and slow turnaround of cultures. Our objectives were to define the performance of T2Candida, a nonculture test, under guidance of a diagnostic stewardship program, and evaluate impact on time to antifungal initiation and antifungal utilization. METHODS: This was a retrospective study of adult medical intensive care unit (MICU) patients with septic shock for whom T2Candida testing was performed from March 2017 to March 2020...

Acute kidney injury (AKI) poses a significant challenge in critically ill patients. To determine the prevalence, risk factors, and mortality rate of AKI among nonsurgical critically ill patients in Jordan University Hospital, we conducted a retrospective study using a consecutive sampling method, including 457 nonsurgical critically ill patients admitted to the medical intensive care unit (MICU) from January to June 2021. The mean age was 63.8 ± 18 years, with 196 (42.8%) developing AKI during their stay in the MICU...

BACKGROUND: Acute liver failure (ALF), previously known as fulminant hepatic failure, has become a common, rapidly progressive, and life-threatening catastrophic hepatic disease in intensive care unit (ICU) due to the continuous increase in drug abuse, viral infection, metabolic insult, and auto-immune cause. At present, plasma exchange (PE) is the main effective alternative treatment for ALF in ICU clinical practice, and high-volume plasma exchange (HVP) has been listed as a grade I recommendation for ALF management in the American Society for Apheresis (ASFA) guidelines...

Mitochondrial calcium concentration ([Ca2+ ]m ) plays an essential role in bioenergetics, and loss of [Ca2+ ]m homeostasis can trigger diseases and cell death in numerous cell types. Ca2+ uptake into mitochondria occurs via the mitochondrial Ca2+ uniporter (MCU), which is regulated by three mitochondrial Ca2+ uptake (MICU) proteins localized in the intermembrane space, MICU1, 2, and 3. We generated a mouse model of systemic MICU3 ablation and examined its physiological role in skeletal muscle. We found that loss of MICU3 led to impaired exercise capacity...

Ferroptosis is an iron- and reactive oxygen species (ROS)-dependent form of regulated cell death, that has been implicated in Alzheimer's disease and Parkinson's disease. Inhibition of cystine/glutamate antiporter could lead to mitochondrial fragmentation, mitochondrial calcium ([Ca2+ ]m ) overload, increased mitochondrial ROS production, disruption of the mitochondrial membrane potential (ΔΨm ), and ferroptotic cell death. The observation that mitochondrial dysfunction is a characteristic of ferroptosis makes preservation of mitochondrial function a potential therapeutic option for diseases associated with ferroptotic cell death...

BACKGROUND: In order to reduce septic shock mortality, international guidelines recommend early treatment implementation, antibiotic therapy (ABT) and hemodynamic optimisation, within 1-h. This retrospective multicentric study aims to investigate the relationship between prehospital ABT delivered within 1st hour and mean blood pressure (MAP) ≥ 65 mmHg at the end of the prehospital stage, and 30-day mortality among patients with septic shock. METHODS: From May 2016 to December 2021, patients with septic shock requiring pre-hospital Mobile Intensive Care Unit intervention (MICU) were retrospectively analysed...

BACKGROUND: Data on diuretic treatment in nephrotic syndrome (NS) are scarce. Our goal was to assess the non-inferiority of the combined oral diuretics (furosemide/hydrochlorothiazide/amiloride) compared to intravenous (i.v.) furosemide in patients with NS and resistant edema. METHODS: We conducted a prospective randomized trial on 22 patients with resistant nephrotic edema (RNE), defined as hypervolemia and a FENa < 0.2%. Based on a computer-generated 1:1 randomization, we assigned patients to receive either intravenous furosemide (40 mg bolus and then continuous administration of 5 mg/h) or oral furosemide (40 mg/day) and hydrochlorothiazide/amiloride (50/5 mg/day) for a period of 5 days...

OBJECTIVES: Klebsiella pneumoniae is an important opportunistic Gram-negative pathogen. This study describes an outbreak due to colistin resistant and Carbapenemase-producing Klebsiella pneumoniae (ColR-CRKP) in a tertiary hospital related to six patients successively admitted to the department of medical intensive care unit (MICU) between March 11 and April 29, 2021. METHODS: Phenotypic characterization was conducted on 16 ColR-CRKP strains obtained from six infected patients and five ColR-CRKP strains isolated from 48 environmental samples, followed by whole genome sequencing (WGS) and PCR analysis...

Nutmeg intoxication is an uncommon precipitant of hyperactive delirium with severe agitation (HDSA) with anticholinergic properties that require a high index of suspicion for diagnosis. We present a case of a young adult who presented to the emergency department (ED) with HDSA. The patient was intubated and transferred to the medical intensive care unit (MICU) due to increasing safety threats unresponsive to multimodal de-escalation. He ultimately self-extubated, reported excessive nutmeg ingestion, and was discharged home after a short period of observation...

OBJECTIVES: Computed tomographic pulmonary angiography (CT-PA) is associated with significant cost, contrast, and radiation exposure. Clinical decision rules (CDRs) reduce the need for diagnostic imaging; however, their utility in the medical intensive care unit (MICU) remains unknown. We explored the diagnostic yield and complications associated with CT-PA (radiation exposure and contrast-induced acute kidney injury [AKI]) while investigating the efficacy of CDRs to reduce unnecessary testing...
