Foreword

Buongiorno! Guten Tag! Good Morning!
My name is Aldo, I am a physician and I live in Milano, Italy. I have always read a lot of medical news, and I have realised how difficult it is to forget to read those news if you’re not disciplined enough or if you don’t make that a habit. So I have decided to help myself and the community, here and on the Telegram app, and share just two articles daily, those that get my attention. All the articles can be searched by Category or Tag.

Buona Lettura! Continue reading Foreword

#Smoking is associated with impaired verbal learning and #memory performance in women more than men

Vascular contributions to cognitive impairment and dementia (VCID) include structural and functional blood vessel injuries linked to poor neurocognitive outcomes. Smoking might indirectly increase the likelihood of cognitive impairment by exacerbating vascular disease risks. Sex disparities in VCID have been reported, however, few studies have assessed the sex-specific relationships between smoking and memory performance and with contradictory results. We investigated the associations between sex, smoking, … Continue reading #Smoking is associated with impaired verbal learning and #memory performance in women more than men

SARS-CoV-2 #Spike Protein Impairs #Endothelial Function via Downregulation of ACE 2

… SARS-CoV-2 infection induces EC inflammation, leading to endotheliitis.1,5 Because S protein decreased ACE2 level and impaired NO bioavailability, we examined whether S protein entry is indispensable for dysfunctional endothelium. As shown in Figure [F], i, the endothelium-dependent vasodilation induced by acetylcholine was impaired in pulmonary arteries isolated from Pseu-Spike-administered hamsters, whereas the endothelium-independent vasodilation induced by sodium nitroprusside was not affected. We also compared … Continue reading SARS-CoV-2 #Spike Protein Impairs #Endothelial Function via Downregulation of ACE 2

#Cardiovascular symptoms affect the patterns of habitual #coffee consumption

Excessive coffee consumption can lead to unpleasant sensations such as tachycardia and heart palpitations. ObjectivesOur aim was to investigate if cardiovascular symptoms can lead to alterations in habitual patterns of coffee consumption. MethodsWe used information from up to 390,435 European ancestry participants in the UK Biobank, aged 39–73 y. Habitual coffee consumption was self-reported, and systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart … Continue reading #Cardiovascular symptoms affect the patterns of habitual #coffee consumption

#Sarcopenia is independently associated with #parietal atrophy in older adults

Highlights•Sarcopenia was common in old adults living in a retirement community (46.1%). •Sarcopenia had moderate-severe global cortical, parietal and medial temporal atrophy. •Sarcopenia is significantly associated with parietal atrophy in older adults. •Age had a significant relationship with global cortical and medial temporal atrophy. AbstractIntroductionAs populations age, sarcopenia becomes a major health problem among adults aged 65 years and older. However, little information is available about … Continue reading #Sarcopenia is independently associated with #parietal atrophy in older adults

Colonization of the #Caenorhabditis elegans gut with human enteric bacterial pathogens leads to proteostasis disruption that is rescued by butyrate

Protein conformational diseases are characterized by misfolding and toxic aggregation of metastable proteins, often culminating in neurodegeneration. Enteric bacteria influence the pathogenesis of neurodegenerative diseases; however, the complexity of the human microbiome hinders our understanding of how individual microbes influence these diseases. Disruption of host protein homeostasis, or proteostasis, affects the onset and progression of these diseases. To investigate the effect of bacteria on host … Continue reading Colonization of the #Caenorhabditis elegans gut with human enteric bacterial pathogens leads to proteostasis disruption that is rescued by butyrate

Mitigating the threat of emerging #infectious diseases; a coevolutionary perspective

“Nothing in biology makes sense except in the light of evolution”[1] and this is no less true for viral pathogens than it is for their host species. To appreciate the full extent of the challenges posed by current and future emerging infectious diseases (EIDs), I believe it is insightful to take a coevolutionary perspective. Coevolution comprises the reciprocal, adaptive genetic changes that occur when two … Continue reading Mitigating the threat of emerging #infectious diseases; a coevolutionary perspective

Non-steroidal anti-inflammatory drug use and outcomes of #COVID-19 in the ISARIC Clinical Characterisation Protocol UK cohort: a matched, prospective cohort study

Early in the pandemic it was suggested that pre-existing use of non-steroidal anti-inflammatory drugs (NSAIDs) could lead to increased disease severity in patients with COVID-19. NSAIDs are an important analgesic, particularly in those with rheumatological disease, and are widely available to the general public without prescription. Evidence from community studies, administrative data, and small studies of hospitalised patients suggest NSAIDs are not associated with poorer … Continue reading Non-steroidal anti-inflammatory drug use and outcomes of #COVID-19 in the ISARIC Clinical Characterisation Protocol UK cohort: a matched, prospective cohort study

Task-Dependent Functional and Effective #Connectivity during Conceptual Processing

Conceptual knowledge is central to cognition. Previous neuroimaging research indicates that conceptual processing involves both modality-specific perceptual-motor areas and multimodal convergence zones. For example, our previous functional magnetic resonance imaging (fMRI) study revealed that both modality-specific and multimodal regions respond to sound and action features of concepts in a task-dependent fashion (Kuhnke P, Kiefer M, Hartwigsen G. 2020b. Task-dependent recruitment of modality-specific and multimodal regions … Continue reading Task-Dependent Functional and Effective #Connectivity during Conceptual Processing
