BACKGROUND: A higher sodium (Na) dialysate concentration is recommended during renal replacement therapy (RRT) of acute kidney injury (AKI) to improve intradialytic hemodynamic tolerance, but it may lead to Na loading to the patient. We aimed to evaluate Na flux according to Na dialysate and infusate concentrations at 140 and 145 mmol/L during hemodialysis (HD) and hemodiafiltration (HDF). METHODS: Fourteen AKI patients that underwent consecutive HD or HDF sessions with Na dialysate/infusate at 140 and 145 mmol/L were included...

BACKGROUND: Acute kidney injury (AKI) requiring renal replacement therapy (RRT) is a serious complication in the ICU that results in increased mortality and risk of chronic kidney disease (CKD). Some studies suggest RRT modality may have an impact on long-term renal recovery after AKI. However, other predictive factors of severe long-term CKD in ICU patients with AKI requiring RRT are unknown. METHODS: We performed an ancillary study of the multicenter ELVIS trial in the population with AKI requiring RRT...

Healthcare workers (HCWs) have faced an increased amount of mental health struggles amidst the COVID-19 pandemic. However, those in conflict-based settings with fragile healthcare systems meet additional challenges. This study reviews violence, conflict and mental health among HCWs in five countries: Syria, Palestine, Yemen, Afghanistan and Lebanon. Our study reports that HCWs are targeted by violence, bombings, mistreatment and different forms of abuse, including verbal and physical. With the additional burdens of the pandemic including prolonged working hours, limited resources and insufficient humanitarian aid, the healthcare workers fall victim to increased levels of burnout and mental illnesses...

The use of conventional methods (immunohistochemistry, pentaplex PCR) for detecting microsatellite instability (MSI), a predictive biomarker of immunotherapy efficacy, is debated for cancers with low MSI prevalence, such as breast cancer (BC). We developed two multiplex drop-off droplet digital PCR (ddPCR) assays targeting four microsatellites, initially identified from public BC whole-genome sequencing dataset. Performances of the assays were investigated and 352 tumor DNA and 28 circulating cell-free DNA from BC patients, with unknown MSI status were blindly screened...

This exploratory prospective study based on 279 individuals showed that plasma levels of neutrophil elastase, myeloperoxidase and circulating DNA of nuclear and mitochondrial origins in non-severe (NS), severe (S) and post-acute phase (PAP) COVID-19 patients were statistically different as compared to the levels in healthy individuals, and revealed the high diagnostic power of these markers in respect to the disease severity. The diagnostic power of NE, MPO, and cir-nDNA as determined by the Area Under Receiver Operating Curves (AUROC) was 0...

BACKGROUND: Fluid overload is associated with worse outcome in critically ill patients requiring continuous renal replacement therapy (CRRT). Net ultrafiltration (UFNET ) allows precise control of the fluid removal but is frequently ceased due to hemodynamic instability episodes. However, approximately 50% of the hemodynamic instability episodes in ICU patients treated with CRRT are not associated with preload dependence (i.e., are not related to a decrease in cardiac preload), suggesting that volume removal is not responsible for these episodes of hemodynamic impairment...

PURPOSE: To determine whether remote ischemic conditioning (RECO), compared to standard care, limits the severity and the consequences of multiple organ failure in patients with septic shock. METHODS: The RECO-Sepsis trial, a prospective, multicenter, randomized, open-label, parallel group trial with blinded assessment of the outcome, was conducted at six intensive care units in France in adult patients with septic shock. Within 12 h after the onset of septic shock, patients were randomized (1:1 ratio) to receive either RECO applied by inflating/deflating (200/0 mmHg for 5/5 min) 4 times a cuff around an arm or a sham procedure every 12 h for 24 h...

PURPOSE: To assess the relationship between pre-operative psychological state, postoperative pain and function one year after total shoulder, hip or knee arthroplasty. METHODS: Patients undergoing shoulder, hip or knee arthroplasty between March 2014 and November 2015 were included. Pain catastrophizing score (PCS) was determined preoperatively, at six months and at one year follow-up. Joint pain at rest was quantified using a Visual Analogue Scale (0‒100)...

INTRODUCTION: In posttraumatic wrist arthritis of intermediate severity, two main palliative procedures are used to preserve some mobility in the wrist: proximal row carpectomy (PRC) and scaphoid excision followed by four corner arthrodesis (4CA). Despite satisfactory overall results, the debate continues about which one provides the best results and long-term outcomes, particularly prevention of arthritis progression. Recent comparative studies now provide us with information about mid- and long-term results...

Rationale: When compared with VenturiMask after extubation, high-flow nasal oxygen provides physiological advantages. Objectives: To establish whether high-flow oxygen prevents endotracheal reintubation in hypoxemic patients after extubation, compared with VenturiMask. Methods: In this multicenter randomized trial, 494 patients exhibiting PaO2 :FiO2 ratio ⩽ 300 mm Hg after extubation were randomly assigned to receive high-flow or VenturiMask oxygen, with the possibility to apply rescue noninvasive ventilation before reintubation...

Background: The Algerian COVID-19 vaccination campaign, which started at the end of January 2021, is marked by a slowly ascending curve despite the deployed resources. To tackle the issue, we assessed the levels and explored determinants of engagement toward the COVID-19 vaccine among the Algerian population. Methods: A nationwide, online-based cross-sectional study was conducted between March 27 and April 30, 2021. A two-stage stratified snowball sampling method was used to include an equivalent number of participants from the four cardinal regions of the country...

A new and suitable multicomponent one-pot reaction was developed for the synthesis of 2-amino-3-cyanopyridine derivatives. BACKGROUND: This synthesis was demonstrated by the efficient and easy access to a variety of substituted 2-aminopyridines using enaminones as key precursors under solvent-free conditions. METHODS: A range of spectroscopic techniques was used to determine and confirm the chemical structures (FTIR, 1 H NMR, 13 C NMR). The antimicrobial potency of synthesized compounds ( 2a - d ) was tested using disk diffusion assays, and the Minimum Inhibitory Concentration (MIC) for the active compounds was determined against a panel of microorganisms, including Gram-positive and Gram-negative bacteria and yeasts...

BACKGROUND: Stress hyperglycemia can persist during an intensive care unit (ICU) stay and result in prolonged requirement for insulin (PRI). The impact of PRI on ICU patient outcomes is not known. We evaluated the relationship between PRI and Day 90 mortality in ICU patients without previous diabetic treatments. METHODS: This is a post hoc analysis of the CONTROLING trial, involving 12 French ICUs. Patients in the personalized glucose control arm with an ICU length of stay ≥ 5 days and who had never previously received diabetic treatments (oral drugs or insulin) were included...

INTRODUCTION: Frozen shoulder is a dreaded complication after rotator cuff repair. HYPOTHESIS: There are psychological determinants for this complication. MATERIALS AND METHODS: We prospectively included 77 consecutive patients who underwent arthroscopic rotator cuff repair between May 2018 and April 2019. Along with a functional evaluation, we determined the Constant score, anxiety and depression levels based on the HADS, and kinesiophobia based on the Tampa Scale preoperatively and 6months after the surgery...

Surgical results in tarsal tunnel syndrome are variable, and etiology seems to be a factor. Three possible etiologies can be distinguished. The aim of the present study was to compare surgical results according to etiology. Three continuous retrospective series (45 patients overall) of tarsal tunnel syndrome were compared. Group 1 presented a permanent intra- or extra-tunnel space-occupying compressive structure. Group 2 presented intermittent intra-tunnel venous dilatations. Group 3 comprised idiopathic tarsal tunnel syndrome...

BACKGROUND: The frequency of acute kidney injury (AKI) can be as high as 50% in the intensive care unit (ICU). Despite the publication of national guidelines in France in 2015 for the use of RRT, there are no data describing the implementation of these recommendations in real-life. METHODS: We performed a nationwide survey of practices from November 15, 2019, to January 24, 2020, in France. An electronic questionnaire based on the items recommended in the national guidelines was sent using an online survey platform, to the chiefs of all ICUs in France...

PURPOSE: Hyperglycaemia is an adaptive response to stress commonly observed in critical illness. Its management remains debated in the intensive care unit (ICU). Individualising hyperglycaemia management, by targeting the patient's pre-admission usual glycaemia, could improve outcome. METHODS: In a multicentre, randomized, double-blind, parallel-group study, critically-ill adults were considered for inclusion. Patients underwent until ICU discharge either individualised glucose control by targeting the pre-admission usual glycaemia using the glycated haemoglobin A1c level at ICU admission (IC group), or conventional glucose control by maintaining glycaemia below 180 mg/dL (CC group)...

INTRODUCTION: At the time of the worrying emergence and spread of bacterial resistance, reducing the selection pressure by reducing the exposure to antibiotics in patients with community-acquired pneumonia (CAP) is a public health issue. In this context, the combined use of molecular tests and biomarkers for guiding antibiotics discontinuation is attractive. Therefore, we have designed a trial comparing an integrated approach of diagnosis and treatment of severe CAP to usual care. METHODS AND ANALYSIS: The multiplex PCR and procalcitonin to reduce duration of antibiotics exposure in patients with severe-CAP (MULTI-CAP) trial is a multicentre (n=20), parallel-group, superiority, open-label, randomised trial...

PURPOSE: The goal was to compare the reliability of a novel 3D method with the standard 2D technique for lower limb discrepancy (LLD) measurement during pre-operative THA planning. METHODS: This prospective study included 100 consecutive patients who underwent THA using 3D planning based on a low-dose CT scan. The LLD was subdivided into three parameters: the intra-articular LLD (IA-LLD), the segmental extra-articular LLD (EA-LLD), and the total LLD (T-LLD). The LLD was assessed with a standard 2D technique on CT scanograms and also with a 3D method...

Rationale: Prolonged mechanical ventilation is often associated with either a decrease (known atrophy) or an increase (supposed injury) in diaphragmatic thickness. Shear wave elastography is a noninvasive technique that measures shear modulus, a surrogate of tissue stiffness and mechanical properties. Objectives: To describe changes in shear modulus (SM) during the ICU stay and the relationship with alterations in muscle thickness. To perform a comprehensive ultrasound-based characterization of histological and force production changes occurring in the diaphragm...
