Takotsubo syndrome: Impact of medical therapies on prognosis. A state of art review.

Tako-Tsubo syndrome (TTS) presents as transient ventricular dysfunction, yet its underlying pathophysiology remains enigmatic. The prognosis of patients presenting with TTS appears to be impaired as compared to the general population and is similar to patients with acute coronary syndromes. Recent investigations have predominantly focused on elucidating therapeutic strategies associated with improved outcomes, particularly among post-menopausal female patients. Current evidence suggests that angiotensin-converting enzyme inhibitors (ACEi) may confer a survival advantage in TTS. Notably, ACEi emerges as the sole therapeutic modality demonstrating efficacy in both acute and chronic clinical courses of TTS. Despite this, the magnitude of survival benefit remains less pronounced than anticipated. This underscores the need for further research to explore additional therapeutic pathways and optimize management strategies for this unique patient cohort. Randomized clinical trials and meta-analysis are paramount in discerning the most effective therapeutic interventions aimed at enhancing survival and ameliorating outcomes in TTS. This review aims to comprehensively synthesize evidence pertaining to the prognostic implications of cardiovascular medications in TTS management.

Patterns of Cerebrospinal Fluid Alzheimer's Dementia Biomarkers in People Living with HIV: Cross-Sectional Study on Associated Factors According to Viral Control, Neurological Confounders and Neurocognition.

People living with HIV (PLWH) age with an excess burden of comorbidities that may increase the incidence of age-related complications. There is controversy surrounding the hypothesis that HIV can accelerate neurodegeneration and Alzheimer's dementia (AD). We performed a retrospective study to analyze the distribution of cerebrospinal fluid (CSF) AD biomarkers (beta amyloid 1-42 fragment, tau, and phosphorylated tau) in adult PLWH (on cART with undetectable viremia, n = 136, with detectable viremia, n = 121, and with central nervous system CNS disorders regardless of viremia, n = 72) who underwent a lumbar puncture between 2008 to 2018; HIV-negative controls with AD were included (n = 84). Five subjects (1.5%) presented CSF biomarkers that were compatible with AD: one was diagnosed with AD, whereas the others showed HIV encephalitis, multiple sclerosis, cryptococcal meningitis, and neurotoxoplasmosis. Regardless of confounders, 79.6% of study participants presented normal CSF AD biomarkers. Isolated abnormalities in CSF beta amyloid 1-42 (7.9%) and tau (10.9%) were associated with age, biomarkers of intrathecal injury, and inflammation, although no HIV-specific feature was associated with abnormal CSF patterns. CSF levels of AD biomarkers very poorly overlapped between HIV-positive clinical categories and AD controls. Despite the correlations with neurocognitive performance, the inter-relationship between amyloid and tau proteins in PLWH seem to differ from that observed in AD subjects; the main driver of the isolated increase in tau seems represented by non-specific CNS inflammation, whereas the mechanisms underlying isolated amyloid consumption remain unclear.
