OBJECTIVES: Patients with gastrointestinal (GI) risk factors who take non-steroidal anti-inflammatory drugs (NSAIDs) should also take gastroprotective agents (GPAs). No studies have evaluated adherence and reasons for non-adherence to GPA and NSAID therapies. METHODS: This was a prospective, multicenter, observational, longitudinal study. Patients attending rheumatology/orthopedic clinics who were co-prescribed NSAID plus GPA for at least 15 days and had risk factors for GI complications were followed up by telephone call. Optimal adherence was defined as taking the drug for ≥80% of prescribed days. Multivariate logistic regression analysis was used to determine factors associated with non-adherence. RESULTS: Of 1,232 patients interviewed, 192 were excluded because of inaccurate data. Of the remaining 1,040 patients, 74% were prescribed low-dose NSAIDs and 99.8% were prescribed a standard or high-dose GPA. In all, 70% of NSAIDs and 63.1% of GPA prescriptions were short term (<30 days). The majority of patients who were prescribed either an NSAID (92.5%) or GPA (85.9%) started therapy. Optimal adherence to GPA or NSAIDs was reported by 79.7% (95% confidence interval (CI): 76.9-82.2%) and 84.1% (95% CI: 81.7-86.3%) of patients, respectively. More adverse events occurred among patients who reported non-optimal adherence than among patients with optimal adherence to GPA (22.1 vs. 1.9%, P<0.0001). As reasons for non-adherence, patients most frequently cited infrequent/low-intensity rheumatic pain (NSAIDs) or forgetfulness (GPAs). Adverse events and short-term treatment were independent factors associated with poor adherence for both NSAIDs and GPAs. History of uncomplicated peptic ulcer and frequent dosing were additional factors associated with non-adherence to NSAIDs. CONCLUSIONS: Most frequent reasons for non-adherence are infrequent/low-intensity rheumatic pain (NSAIDs) or forgetfulness (GPAs). Short-term treatment and adverse events were associated with poor adherence for both therapies. © 2012 by the American College of Gastroenterology.

Our understanding of the pathophysiological mechanisms of heart failure (HF) has changed considerably in recent years, progressing from a merely haemodynamic viewpoint to a concept of systemic and multifactorial involvement in which numerous mechanisms interact and concatenate. The effects of these mechanisms go beyond the heart itself, to other organs of vital importance such as the kidneys, liver and lungs. Despite this, the pathophysiology of acute HF still has aspects that elude our deeper understanding. Haemodynamic overload, venous congestion, neurohormonal systems, natriuretic peptides, inflammation, oxidative stress and its repercussion on cardiac and vascular remodelling are currently considered the main players in acute HF. Starting with the concept of acute HF, this review provides updates on the various mechanisms involved in this disease. © 2015 Elsevier España, S.L.U. y Sociedad Española de Medicina Interna (SEMI).

Previous studies have generally found a relationship between negative and cognitive symptoms in schizophrenia. The present study investigated the relationship between the 5 PANSS factors of a recent consensus model developed by NIMH researchers, and cognitive performance as assessed with the MATRICS Consensus Cognitive Battery (MCCB) in 80 patients with schizophrenia using correlation and regression analyses. The PANSS Cognitive factor showed a small to moderate significant association with MCCB Speed of processing, Working memory, Verbal learning, the Neurocognitive composite score, and the Overall composite score. Notably, however, no relationship was found between the PANSS Negative factor and any of the MCCB scores. The Positive, Excited and Depressed factors also did not show associations with the MCCB. These results highlight the need for refined assessment instruments and support the relative independence of cognition from other domains of psychopathology, including negative symptoms, in patients with schizophrenia. © 2015 Elsevier Ireland Ltd.

It has been suggested that data on positive and negative psychotic symptoms in patients with schizophrenia as assessed using different scales may be combined. For the first time, we assessed correlations between the positive syndrome subscale of the Positive and Negative Syndrome Scale (PANSS-P) and the Scale for the Assessment of Positive Symptoms (SAPS), and between the negative syndrome subscale of the Positive and Negative Syndrome Scale (PANSS-N) and the Scale for the Assessment of Negative Symptoms (SANS) in patients with bipolar disorder. We also aimed to confirm these correlations in patients with schizophrenia. This cross-sectional study was conducted with a group of 94 patients (40 diagnosed with bipolar disorder, 54 with schizophrenia). Assessments were carried out using the PANSS, SAPS and SANS. Large significant correlations were found between the PANSS-P and SAPS, and between the PANSS-N and SANS, in both the bipolar disorder group and the schizophrenia group. These results confirm previous findings regarding correlations between these scales in schizophrenia, and support the hypothesis that similar correlations exist in bipolar disorder. Therefore, our data support the potential usefulness in collaborative research of combining results from different scales for the assessment of psychotic symptoms in patients with bipolar disorder. © 2014 Elsevier Ireland Ltd.

Transthyretin (TTR) is a plasma homotetrameric protein implicated in fatal systemic amyloidoses. TTR tetramer dissociation precedes pathological TTR aggregation. Native state stabilizers are promising drugs to treat TTR amyloidoses. Here we repurpose tolcapone, an FDA-approved molecule for Parkinson's disease, as a potent TTR aggregation inhibitor. Tolcapone binds specifically to TTR in human plasma, stabilizes the native tetramer in vivo in mice and humans and inhibits TTR cytotoxicity. Crystal structures of tolcapone bound to wild-type TTR and to the V122I cardiomyopathy-associated variant show that it docks better into the TTR T4 pocket than tafamidis, so far the only drug on the market to treat TTR amyloidoses. These data indicate that tolcapone, already in clinical trials for familial amyloid polyneuropathy, is a strong candidate for therapeutic intervention in these diseases, including those affecting the central nervous system, for which no small-molecule therapy exists. © 2016, Nature Publishing Group.
