Osteoarthritis is a common condition, but curative therapies are limited. Here, Liu and colleagues developed a biodegradable scaffold using PLLA [poly(L-lactic acid)] nanofibers that when placed under applied force generated a piezoelectric charge, leading to improved chondrogenesis in vitro. Rabbits with osteochondral defects in the medial femoral condyle that were treated with the PLLA scaffold… Continue reading Exercise-induced piezoelectric stimulation for cartilage regeneration in rabbits

Estimation of the global prevalence of dementia in 2019 and forecasted prevalence in 2050: an analysis for the Global Burden of Disease Study 2019
SummaryBackgroundGiven the projected trends in population ageing and population growth, the number of people with dementia is expected to increase. In addition, strong evidence has emerged supporting the importance of potentially modifiable risk factors for dementia. Characterising the distribution and magnitude of anticipated growth is crucial for public health planning and resource prioritisation. This study… Continue reading Estimation of the global prevalence of dementia in 2019 and forecasted prevalence in 2050: an analysis for the Global Burden of Disease Study 2019
Worldwide Bayesian Causal Impact Analysis of Vaccine Administration on Deaths and Cases Associated with COVID-19: A BigData Analysis of 145 Countries
Policy makers and mainstream news anchors have promised the public that the COVID-19 vaccine rollout worldwide would reduce symptoms, and thereby cases and deaths associated with COVID-19. While this vaccine rollout is still in progress, there is a large amount of public data available that permits an analysis of the effect of the vaccine rollout… Continue reading Worldwide Bayesian Causal Impact Analysis of Vaccine Administration on Deaths and Cases Associated with COVID-19: A BigData Analysis of 145 Countries
Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infections
Reports of waning vaccine-induced immunity against COVID-19 have begun to surface. With that, the comparable long-term protection conferred by previous infection with SARS-CoV-2 remains unclear. Methods We conducted a retrospective observational study comparing three groups: (1)SARS-CoV-2-naïve individuals who received a two-dose regimen of the BioNTech/Pfizer mRNA BNT162b2 vaccine, (2)previously infected individuals who have not been… Continue reading Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infections
Relationship of circulating total bilirubin, UDP-glucuronosyltransferases 1A1 and the development of non-alcoholic fatty liver disease: a cross-sectional study
This study aimed to investigate the correlation of circulating total bilirubin (TB) and UGT1A1 with NAFLD in Chinese Han population. Methods172 adults were enrolled from the Qingdao Municipal Hospital from May 2019 to October 2020. All individuals were examined with MRI-PDFF and divided into no steatosis, mild steatosis, moderate steatosis, and severe steatosis groups according… Continue reading Relationship of circulating total bilirubin, UDP-glucuronosyltransferases 1A1 and the development of non-alcoholic fatty liver disease: a cross-sectional study
Cross-reactive memory T cells associate with protection against SARS-CoV-2 infection in COVID-19 contacts
Cross-reactive immune responses to SARS-CoV-2 have been observed in pre-pandemic cohorts and proposed to contribute to host protection. Here we assess 52 COVID-19 household contacts to capture immune responses at the earliest timepoints after SARS-CoV-2 exposure. Using a dual cytokine FLISpot assay on peripheral blood mononuclear cells, we enumerate the frequency of T cells specific… Continue reading Cross-reactive memory T cells associate with protection against SARS-CoV-2 infection in COVID-19 contacts
Dulaglutide and Incident Atrial Fibrillation or Flutter in patients with type 2 Diabetes; a post-hoc analysis from the REWIND Randomized Trial
Diabetes mellitus is an independent risk factor for atrial fibrillation or atrial flutter (atrial arrythmia, AA). Additionally, some diabetes medications may influence AA incidence. The aim of this post hoc analysis was to assess the occurrence of AA during the study period in patients with type 2 diabetes treated with once weekly subcutaneous dulaglutide vs… Continue reading Dulaglutide and Incident Atrial Fibrillation or Flutter in patients with type 2 Diabetes; a post-hoc analysis from the REWIND Randomized Trial
Thyroiditis after Coronavirus Disease 2019 (COVID-19) mRNA Vaccine: A Case Series
Highlights1)Thyrotoxicosis with palpitation, and neck tenderness is the most common presentation of thyroiditis. The patients with new onset of thyrotoxicosis should be asked about history of mRNA-vaccine injection for the possible etiology. 2)mRNA vaccine induced thyroiditis could occur 10-20 days after the first dose or the second dose. 3)Management is to relieve the symptom of… Continue reading Thyroiditis after Coronavirus Disease 2019 (COVID-19) mRNA Vaccine: A Case Series
Association between vitamin D status and risk of covid-19 in-hospital mortality: A systematic review and meta-analysis of observational studies
Some earlier studies reported higher risk of COVID-19 mortality in patients with vitamin D deficiency, while some others failed to find such as association. Due to inconsistences between earlier meta-analyses and needs for an updated study, we conducted current systematic review and meta-analysis on the association between vitamin D status and risk of COVID-19 in-hospital… Continue reading Association between vitamin D status and risk of covid-19 in-hospital mortality: A systematic review and meta-analysis of observational studies
