Meta Analysis Comparative Study
Short vs long-course antibiotic therapy in pyelonephritis: a comparison of systematic reviews and guidelines for the SIMI choosing wisely campaign.
The Italian Society of Internal Medicine (SIMI) Choosing Wisely Campaign has recently proposed, among its five items, to reduce the prescription of long-term intravenous antibiotics if not indicated. The aim of our study was to assess the available evidences on optimal duration of antibiotic treatment in pyelonephritis through a systematic review of secondary studies. ⋯ Short-course antibiotic treatment is at least as effective as longer courses for both microbiological and clinical success in the treatment of acute uncomplicated pyelonephritis.

Review Meta Analysis
Efficacy and safety of colchicine for secondary prevention of coronary heart disease: a systematic review and meta-analysis.
To evaluate the efficacy and safety of colchicine for secondary prevention of coronary heart disease (CHD), relevant randomized controlled trials (RCTs) were identified by searching several databases from the creation date to August 31, 2020 and were reviewed. Eight eligible trials of colchicine therapy involving a total of 11, 463 patients were included (5, 776 subjects received colchicine, while 5, 687 subjects were in the respective control arms), and the outcome was reported as risk ratio (RR) and 95% confidence interval (CI), as the relative measure of association. Overall, the incidences of major adverse cardiovascular events (MACEs) (RR 0.70; 95% CI 0.61-0.80), myocardial infarction (MI) (RR 0.77; 95% CI 0.64-0.94), emergency readmission due to CHD (RR 0.70; 95% CI 0.58-0.86), and ischemic stroke (RR 0.49; 95% CI 0.30-0.79) were lower in the colchicine group than in the placebo arm. ⋯ Although the incidence of diarrhea in the colchicine treatment group was higher than that in the placebo arms (RR 2.53; 95% CI 1.17, 5.48), the symptoms disappeared rapidly after drug withdrawal, and no serious adverse reactions occurred. In summary, colchicine is an accessible, safe, and effective drug that could be successfully utilized for the secondary prevention of CHD. The tolerability and benefits should be confirmed in in-depth clinical trials.

Review Meta Analysis
Prevention of anthracycline-induced cardiotoxicity: a systematic review and meta-analysis.
Anthracyclines are extensively used in oncologic patients, in particular for breast cancer and hematological malignancies. Cardiac injury is a potentially dangerous side effect of these drugs. In this systematic review, we analyzed published randomized controlled trials (RCTs) to assess if potential cardioprotective drugs (i.e., renin-angiotensin-aldosterone system [RAAS] blockers and β-blockers) may prevent heart damage by anthracyclines. ⋯ Hypotension was non-significantly increased in the cardioprotective arm (OR 3.91, 95% CI 0.42, 36.46, 3 studies). Cardioprotective drugs reduce anthracycline-induced cardiac damage as assessed by echocardiographic parameters. The clinical relevance of this positive effect is still to be defined.

Refractory cardiogenic shock (RCS) or refractory cardiac arrest (RCA) complicating acute coronary syndrome (ACS) is associated with extremely high mortality rate. Veno-arterial extracorporeal life support (VA-ECLS) represents a valuable therapeutic option to stabilize patients' condition before or at the time of emergency revascularization. We analyzed 29 consecutive patients with RCS or RCA complicating ACS, and implanted with VA-ECLS in two centers who have adopted a similar, structured approach to ECLS implantation. ⋯ Survivors were younger, with shorter low-flow time, and with ECLS mainly implanted for RCS. At multivariate analysis, levels of lactate at ECLS implantation (OR 4.32, 95%CI 1.01-18.51, p = 0.049) emerged as the only variable that independently predicted survival. In patients with RCA or RCS complicating ACS who are percutaneously implanted with ECLS before or at the time of coronary revascularization, in hospital survival rate is higher than 30%. Level of lactate at ECLS implantation appears to be the most important factor to predict survival.

Observational Study
Influence of ventilatory strategies on outcomes and length of hospital stay: assist-control and synchronized intermittent mandatory ventilation modes.
The use of synchronized intermittent mandatory ventilation with pressure support ventilation (SIMV + PSV) mode has been discontinued. This study analyzed the association between medical outcomes related to the use of assist-control (A/C) and SIMV + PSV in an intensive care unit. In this observational and retrospective study, modes of ventilation and medical data were collected from electronic medical records for three consecutive years and were related to medical outcomes (mortality), duration of mechanical ventilation, length of hospital stay and the need for tracheostomy. ⋯ Of the participants, 151/345 (43.77%) were on SIMV + PSV and 194/345 (56.23%) were on A/C. The comparative analysis between the modes of ventilation showed no significant differences in length of hospital stay (p = 0.675), duration of mechanical ventilation (p = 0.952), mortality (p = 0.241), failed extubation (p = 0.411) and the need for tracheostomy (p = 0.301). SIMV + PSV as a mode of ventilation showed similar statistical results to the A/C mode, when compared to analyzed medical outcomes.
