SMASH-U classification: a tool for aetiology-oriented management of patients with acute haemorrhagic stroke.
Intracerebral haemorrhage (ICH) is responsible for disproportionately high morbidity and mortality rates. The most used ICH classification system is based on the anatomical site. We used SMASH-U, an aetiological based classification system for ICH by predefined criteria: structural vascular lesions (S), medication (M), amyloid angiopathy (A), systemic disease (S), hypertension (H), or undetermined (U). ⋯ At multivariable analysis, medication and systemic disease groups resulted associated with the outcome (odds ratio 3.47; 95% CI 1.15-10.46; P = 0.02 and 3.64; 95% CI 1.47-9.01; P = 0.005, respectively). Furthermore, age and high NIHSS at admission resulted significantly associated with intra-hospital mortality (odds ratio 1.01; 95% CI 1-1.03; P = 0.04 and 1.12; 95% CI 1.03-1.22; P = 0.008, respectively). In our retrospective study, the aetiology-oriented classification system SMASH-U showed to be potentially predictive of intra-hospital mortality of acute haemorrhagic stroke patients and it may support clinicians in the acute ICH management.

The predictive value of the HEART and GRACE scores for major adverse cardiac events in patients with acute chest pain.
The history, electrocardiogram, age, risk factors, troponin (HEART) and global registry of acute coronary events (GRACE) scoring systems are commonly used to risk stratify patients with chest pain. This study investigated the application of these scores in predicting the short-term risk of a major adverse cardiac event (MACE) in patients with chest. A total of 509 patients were analyzed. ⋯ The Hosmer-Lemeshow statistic revealed that the HEART and GRACE scores had values of 8.68 (P = 0.39) and 10.45 (P = 0.11), respectively. The percentages of patients with HEART scores of 0-3, 4-6, and 7-10 were 3.0%, 26.2%, and 46.3%, respectively, in those with a MACE within 30 days. The findings show that while both scoring systems are useful, the HEART score is superior to the GRACE score for predicting the occurrence of MACE within 30 days in patients with chest pain.

Prevalence and correlates of hyperkalemia in a renal nutrition clinic.
Hyperkalemia (HK) is a frequent complication of chronic kidney disease (CKD). Vegetable-based renal diets are considered at risk due to the high potassium (K) content. The aim of this study was to describe the prevalence and correlates of chronic hyperkalemia (HK) in CKD patients on nutritional care, and in particular, the risk of HK in patients on plant-based versus animal-based low-protein diets. ⋯ Hyperkalemia is mostly mild, being moderate to severe HK quite infrequent. Hyperkalemia was not associated with higher risk of mortality, whereas a trend, although not statistically significant, was observed for lower ESRD-free survival. Plant-based low-protein diet is not associated with significant higher prevalence of HK with respect to animal-based LPD at the same residual kidney function.

Acute hepatic porphyria (AHP) attacks begin with abdominal pain and can progress to severe life-threatening conditions. Early diagnosis and treatment may prevent these complications. We investigated the difference between the severity of porphyria attacks before and after porphyria diagnosis. ⋯ These results remained significant after simple univariate logistic regression for ICU admission [odds ratio (OR) 0.01, 95% confidence interval (CI) 0.00-0.12], prolonged hospital stay (OR 0.08, 95% CI 0.01-0.41), seizures or neurological symptoms (OR 0.06, 95% CI 0.01-0.30), and severe hyponatremia (OR 0.02, 95% CI 0.00-0.20). Previously diagnosed AHP patients have a significantly milder attack course as compared to previously undiagnosed patients. Family screening following sentinel cases might prevent severe AHP attacks.

In patients with the novel coronavirus (COVID-19) infection, the echocardiographic assessment of the right ventricle (RV) represents a pivotal element in the understanding of current disease status and in monitoring disease progression. The present manuscript is aimed at specifically describing the echocardiographic assessment of the right ventricle, mainly focusing on the most useful parameters and the time of examination. The RV direct involvement happens quite often due to preferential lung tropism of COVID-19 infection, which is responsible for an interstitial pneumonia characterized also by pulmonary hypoxic vasoconstriction (and thus an RV afterload increase), often evolving in acute respiratory distress syndrome (ARDS). ⋯ They have been selected on the basis of their feasibility (that is easy to be measured, even in short time) and usefulness for clinical monitoring. It is advisable to measure the same parameters in the single patient (based also on the availability of valid acoustic windows) which are identified in the first examination and repeated in the following ones, to guarantee a reliable monitoring. Information gained from a clinically-guided echocardiographic assessment holds a clinical utility in the single patients when integrated with biohumoral data (indicating systemic activation), blood gas analysis (reflecting COVID-19-induced lung damage) and data on ongoing therapies (in primis ventilatory settings).
