Observational Study
Contemporary impact of circadian symptom-onset patterns of acute ST-Segment elevation myocardial infarction on long-term outcomes after primary percutaneous coronary intervention.
Daytime variation with regard to onset time of ST-elevation myocardial infarction (STEMI) symptoms has been observed. Nevertheless, with the advanced medical therapy, it is not uncertainty if a similar circadian pattern of STEMI symptom onset occurs, as well as its possible impact on clinical outcomes. Few long-term data are available. We assess the impact of circadian symptom-onset patterns of STEMI on major adverse cardiovascular events (MACE) in more contemporary patients treated with primary percutaneous coronary intervention (PPCI). ⋯ Circadian variation of STEMI symptom-onset with morning predominance still exists in contemporary practice. Night symptom-onset STEMI was independently associated with increased risk of MACE in Chinese patients treated with PPCI.

Acute lymphoblastic leukaemia (ALL) is often characterized by broad clinical and biological heterogeneity, as well as recurrent genetic aberrations. Despite remarkable improvements in the treatment outcome in paediatric ALL over the past several decades, it remains a leading cause of morbidity and mortality among children. Cytokines have been extensively studied in haematologic diseases; however, the mechanisms by which cytokines contribute to ALL pathogenesis remain poorly understood. ⋯ Our study reveals an important role for IL-33/IL1RL1 axis in supporting ALL which may represent a novel treatment for paediatric patients.KEY MESSAGESBoth IL-33 and IL1RL1 levels are upregulated in primary ALL samples.IL-33 increased both p38 MAPK and AKT activation in ALL.IL-33 promotes survival and cell cycle progression of ALL cells via activating p38 MAPK.

To evaluate the impact the COVID-19-related national lockdown has had on Ophthalmologic Outpatient Care in an Italian Tertiary Medical Centre. ⋯ During the various lockdown periods, at our institution the volume of outpatient ophthalmological visits drastically dropped. This testifies the dramatic impact the COVID-19 pandemic has had on the supply of ophthalmic care.

Background and aim: Since the relation between Helicobacter pylori (H. pylori) and atherosclerosis has been evidenced, we aimed to analyze whether there is a relationship between the patient's H. pylori infection and age, gender, BMI, blood lipids, and carotid plaque formation. Methods: 810 patients from January 2016 to December 2019 were enrolled in this study, and divided the subjects into H. pylori (+) group and H. pylori (-) group based on the results of UBT. To analyze whether H. pylori infection is related to gender, age, BMI, blood lipids, and neck vascular plaque formation. ⋯ The multi-variant analysis showed that patients with H. pylori infection are prone to have higher BMI, triglycerides, and neck vascular plaque formation over 1.4-times higher in non-infected individuals. KEY MESSAGESH. pylori infection is an independent risk factor for higher BMI, triglyceride, and neck vascular plaque formation. H. pylori can accelerate vascular plaque formation through increasing BMI and triglyceride.

Osteoarthritis (OA) is the most common condition affecting human joints. Along with mechanical and genetic factors, low-grade inflammation is increasingly supported as a causal factor in the development of OA. Gut microbiota and intestinal permeability, via the disruption of tight junction competency, are proposed to explain a gut-joint axis through the interaction with the host immune system. ⋯ KEY MESSAGESPrevious studies and methods have underestimated the impact of the gut-joint axis in osteoarthritis and have focussed on the characterisation of microbiota phenotypes rather than clear molecular mediators of disease. Gut dysbiosis is related to higher levels of bacterial toxins that elicit cartilage and synovium inflammatory pathways. Future research may benefit from focussing on both tight junctions and bacterially-produced products.
