RESUMEN
BACKGROUND: Increased protein provision might ameliorate muscle wasting and improve long-term outcomes in critically ill patients. The aim of the PRECISe trial was to assess whether higher enteral protein provision (ie, 2·0 g/kg per day) would improve health-related quality of life and functional outcomes in critically ill patients who were mechanically ventilated compared with standard enteral protein provision (ie, 1·3 g/kg per day). METHODS: The PRECISe trial was an investigator-initiated, double-blinded, multicentre, parallel-group, randomised controlled trial in five Dutch hospitals and five Belgian hospitals. Inclusion criteria were initiation of invasive mechanical ventilation within 24 h of intensive care unit (ICU) admission and an expected duration of invasive ventilation of 3 days or longer. Exclusion criteria were contraindications for enteral nutrition, moribund condition, BMI less than 18 kg/m2, kidney failure with a no dialysis code, or hepatic encephalopathy. Patients were randomly assigned to one of four randomisation labels, corresponding with two study groups (ie, standard or high protein; two labels per group) in a 1:1:1:1 ratio through an interactive web-response system. Randomisation was done via random permuted-block randomisation in varying block sizes of eight and 12, stratified by centre. Participants, care providers, investigators, outcome assessors, data analysts, and the independent data safety monitoring board were all blinded to group allocation. Patients received isocaloric enteral feeds that contained 1·3 kcal/mL and 0·06 g of protein/mL (ie, standard protein) or 1·3 kcal/mL and 0·10 g of protein/mL (ie, high protein). The study-nutrition intervention was limited to the time period during the patient's ICU stay in which they required enteral feeding, with a maximum of 90 days. The primary outcome was EuroQoL 5-Dimension 5-level (EQ-5D-5L) health utility score at 30 days, 90 days, and 180 days after randomisation, adjusted for baseline EQ-5D-5L health utility score. This trial was registered with ClinicalTrials.gov (NCT04633421) and is closed to new participants. FINDINGS: Between Nov 19, 2020, and April 14, 2023, 935 patients were randomly assigned. 335 (35·8%) of 935 patients were female and 600 (64·2%) were male. 465 (49·7%) of 935 were assigned to the standard protein group and 470 (50·3%) were assigned to the high protein group. 430 (92·5%) of 465 patients in the standard protein group and 419 (89·1%) of 470 patients in the high protein group were assessed for the primary outcome. The primary outcome, EQ-5D-5L health utility score during 180 days after randomisation (assessed at 30 days, 90 days, and 180 days), was lower in patients allocated to the high protein group than in those allocated to the standard protein group, with a mean difference of -0·05 (95% CI -0·10 to -0·01; p=0·031). Regarding safety outcomes, the probability of mortality during the entire follow-up was 0·38 (SE 0·02) in the standard protein group and 0·42 (0·02) in the high protein group (hazard ratio 1·14, 95% CI 0·92 to 1·40; p=0·22). There was a higher incidence of symptoms of gastrointestinal intolerance in patients in the high protein group (odds ratio 1·76, 95% CI 1·06 to 2·92; p=0·030). Incidence of other adverse events did not differ between groups. INTERPRETATION: High enteral protein provision compared with standard enteral protein provision resulted in worse health-related quality of life in critically ill patients and did not improve functional outcomes during 180 days after ICU admission.

BACKGROUND: Whether acetazolamide, a carbonic anhydrase inhibitor that reduces proximal tubular sodium reabsorption, can improve the efficiency of loop diuretics, potentially leading to more and faster decongestion in patients with acute decompensated heart failure with volume overload, is unclear. METHODS: In this multicenter, parallel-group, double-blind, randomized, placebo-controlled trial, we assigned patients with acute decompensated heart failure, clinical signs of volume overload (i.e., edema, pleural effusion, or ascites), and an N-terminal pro-B-type natriuretic peptide level of more than 1000 pg per milliliter or a B-type natriuretic peptide level of more than 250 pg per milliliter to receive either intravenous acetazolamide (500 mg once daily) or placebo added to standardized intravenous loop diuretics (at a dose equivalent to twice the oral maintenance dose). Randomization was stratified according to the left ventricular ejection fraction (≤40% or >40%). The primary end point was successful decongestion, defined as the absence of signs of volume overload, within 3 days after randomization and without an indication for escalation of decongestive therapy. Secondary end points included a composite of death from any cause or rehospitalization for heart failure during 3 months of follow-up. Safety was also assessed. RESULTS: A total of 519 patients underwent randomization. Successful decongestion occurred in 108 of 256 patients (42.2%) in the acetazolamide group and in 79 of 259 (30.5%) in the placebo group (risk ratio, 1.46; 95% confidence interval [CI], 1.17 to 1.82; P<0.001). Death from any cause or rehospitalization for heart failure occurred in 76 of 256 patients (29.7%) in the acetazolamide group and in 72 of 259 patients (27.8%) in the placebo group (hazard ratio, 1.07; 95% CI, 0.78 to 1.48). Acetazolamide treatment was associated with higher cumulative urine output and natriuresis, findings consistent with better diuretic efficiency. The incidence of worsening kidney function, hypokalemia, hypotension, and adverse events was similar in the two groups. CONCLUSIONS: The addition of acetazolamide to loop diuretic therapy in patients with acute decompensated heart failure resulted in a greater incidence of successful decongestion.

INTRODUCTION: The prevalence of chronic knee pain is increasing. Osteoarthritis (OA) and persistent postsurgical pain (PPSP) are two important causes of knee pain. Chronic knee pain is primarily treated with medications, physiotherapy, life-style changes and intra-articular infiltrations. A radiofrequency treatment (RF) of the genicular nerves is a therapeutical option for refractory knee pain. This study investigates the effectiveness and cost-effectiveness of conventional and cooled RF in patients suffering from chronic, therapy resistant, moderate to severe knee pain due to OA and PPSP. METHODS AND ANALYSIS: The COGENIUS trial is a double-blinded, randomised controlled trial with 2-year follow-up. Patients and outcome assessors are blinded. Patients will be recruited and treated in Belgium and the Netherlands. All PPSP after a total knee prothesis and OA patients (grades 2-4) will undergo a run-in period of 1-3 months where conservative treatment will be optimised. After the run-in period, 200 patient per group will be randomised to conventional RF, cooled RF or a sham procedure following a 2:2:1 ratio. The analysis will include a comparison of the effectiveness of each RF treatment with the sham procedure and secondarily between conventional and cooled RF. All comparisons will be made for each indication separately. The primary outcome is the Western Ontario and McMaster Universities Osteoarthritis Index score at 6 months. Other outcomes include knee pain, physical functionality, health-related quality of life, emotional health, medication use, healthcare and societal cost and adverse events up to 24 months postintervention. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee of the University of Antwerp (Number Project ID 3069-Edge 002190-BUN B3002022000025), the Ethics committee of Maastricht University (Number NL80503.068.22-METC22-023) and the Ethics committee of all participating hospitals. Results of the study will be published in international peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05407610.

BACKGROUND: Critically ill patients are subject to severe skeletal muscle wasting during intensive care unit (ICU) stay, resulting in impaired short- and long-term functional outcomes and health-related quality of life. Increased protein provision may improve functional outcomes in ICU patients by attenuating skeletal muscle breakdown. Supporting evidence is limited however and results in great variety in recommended protein targets. METHODS: The PRECISe trial is an investigator-initiated, bi-national, multi-center, quadruple-blinded randomized controlled trial with a parallel group design. In 935 patients, we will compare provision of isocaloric enteral nutrition with either a standard or high protein content, providing 1.3 or 2.0 g of protein/kg/day, respectively, when fed on target. All unplanned ICU admissions with initiation of invasive mechanical ventilation within 24 h of admission and an expected stay on ventilator support of at least 3 days are eligible. The study is designed to assess the effect of the intervention on functional recovery at 1, 3, and 6 months following ICU admission, including health-related quality of life, measures of muscle strength, physical function, and mental health. The primary endpoint of the trial is health-related quality of life as measured by the Euro-QoL-5D-5-level questionnaire Health Utility Score. Overall between-group differences will be assessed over the three time points using linear mixed-effects models. DISCUSSION: The PRECISe trial will evaluate the effect of protein on functional recovery including both patient-centered and muscle-related outcomes. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04633421 . Registered on November 18, 2020. First patient in (FPI) on November 19, 2020. Expected last patient last visit (LPLV) in October 2023.

AIMS: To describe the baseline characteristics of participants in the Acetazolamide in Decompensated Heart Failure with Volume Overload (ADVOR) trial and compare these with other contemporary diuretic trials in acute heart failure (AHF). METHODS AND RESULTS: ADVOR recruited 519 patients with AHF, clinically evident volume overload, elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) and maintenance loop diuretic therapy prior to admission. All participants received standardized loop diuretics and were randomized towards once daily intravenous acetazolamide (500 mg) versus placebo, stratified according to study centre and left ventricular ejection fraction (LVEF) (≤40% vs. >40%). The primary endpoint was successful decongestion assessed by a dedicated score indicating no more than trace oedema and no other signs of congestion after three consecutive days of treatment without need for escalating treatment. Mean age was 78 years, 63% were men, mean LVEF was 43%, and median NT-proBNP 6173 pg/ml. The median clinical congestion score was 4 with an EuroQol-5 dimensions health utility index of 0.6. Patients with LVEF ≤40% were more often male, had more ischaemic heart disease, higher levels of NT-proBNP and less atrial fibrillation. Compared with diuretic trials in AHF, patients enrolled in ADVOR were considerably older with higher NT-proBNP levels, reflecting the real-world clinical situation. CONCLUSION: ADVOR is the largest randomized diuretic trial in AHF, investigating acetazolamide to improve decongestion on top of standardized loop diuretics. The elderly enrolled population with poor quality of life provides a good representation of the real-world AHF population. The pragmatic design will provide novel insights in the diuretic treatment of patients with AHF.

AIMS: Decisive evidence on the optimal diuretic agent, dosing schedule, and administration route is lacking in acute heart failure (AHF) with congestion. The Acetazolamide in Decompensated heart failure with Volume OveRload (ADVOR) trial is designed to test the hypothesis that the carbonic anhydrase inhibitor acetazolamide, a potent inhibitor of proximal tubular sodium reabsorption, improves decongestion when combined with loop diuretic therapy in AHF, potentially leading to better clinical outcomes. METHODS: The ADVOR trial is set up as a multicentre, randomized, double-blind, placebo-controlled study, aiming to recruit 519 patients with AHF and clinically evident volume overload. All study participants receive high-dose intravenous loop diuretics as background therapy and are randomized towards intravenous acetazolamide at a dose of 500 mg once daily vs. placebo, stratified according to including study centre and ejection fraction (< 40% vs. ≥ 40%). The primary endpoint is successful decongestion with no more than trace oedema assessed on the third morning after hospital admission, with good diuretic efficacy defined as a urine output > 3.5 L during the first 30-48 h of decongestive treatment. Secondary endpoints include all-cause mortality or heart failure readmission after 3 months, length of hospital stay for the index admission, and longitudinal changes in the EuroQol-5 dimensions questionnaire. CONCLUSION: ADVOR will investigate if acetazolamide combined with loop diuretic therapy improves decongestion in AHF with volume overload.
