Background: Renal function is a powerful prognostic variable in patients with heart failure (HF). Hospitalisations for acute HF (AHF) may be associated with further worsening of renal function (WRF). Methods and results: We analysed the clinical significance of WRF in 318 consecutive patients admitted at our institute for AHF. WRF was defined as the occurrence, at any time during the hospitalisation, of both a ≥25% and a ≥ 0.3 mg/dL increase in serum creatinine (s-Cr) from admission (WRF-Abs-%). Results: Patients were followed for 480 ± 363 days. Fifty-three patients (17%) died and 132 (41%) were rehospitalised for HF. WRF-Abs-% occurred in 107 (34%) patients. At multivariable survival analysis, WRF-Abs-% was an independent predictor of death or HF rehospitalisation (adjusted HR, 1.47; 95%CI, 1.13-1.81; p = 0.024). The independent predictors of WRF-Abs-%, evaluated using multivariable logistic regression, were history of chronic kidney disease (p = 0.002), LV ejection fraction (p = 0.012), furosemide daily dose (p = 0.03) and NYHA class (p = 0.05) on admission. Conclusion: WRF is a frequent finding in patients hospitalised for AHF and is associated with a poor prognosis. Severity of HF and daily furosemide dose are the most important predictors of the occurrence of WRF.

Aims: Brain natriuretic peptide (BNP), NT-proBNP and troponins are useful for the assessment of patients with heart failure. Few data exist about their serial changes and their prognostic value in patients with acute heart failure (AHF). Methods and results: NT-proBNP and troponin-T plasma levels were measured at baseline, after 6, 12, 24, 48 h and at discharge in 116 consecutive patients with AHF and no evidence of acute coronary syndrome. NT-proBNP levels were 4421 pg/mL at baseline, declined after 24 h and reached their nadir at 48 h (2703 pg/mL). Troponin-T was detectable in 48% of patients. During a median follow-up of 184 days, 52 patients died or had a non-fatal cardiovascular hospitalisation. At a multivariable analysis including clinical and echo-Doppler variables, NTproBNP plasma levels at discharge, detectable troponin-T plasma levels, and NYHA class at discharge were the only independent prognostic factors. Conclusion: In patients with AHF, NT-proBNP levels decline 24 h after the initiation of intravenous therapy and troponin-T is detectable in 48% of cases. NT-proBNP levels at discharge, detectable troponin-T levels, NYHA class and serum sodium have independent prognostic value.

This review highlights the validated goniometer apps that physiatrists and other health care practitioners can use with confidence in research and clinical practice. We found 12 apps corresponding to these criteria, but there is a need for validation studies on available or new apps focused on goniometric measurement in dynamic conditions, eg, during gait or when performing therapeutic exercises.

i-SCIM3 was found to be a consistent, reliable, and valid scale for use in the clinical setting. It is the first validated scale in Italian for patients with SCL.
