In the CoreValve High-Risk Trial, patients with severe symptomatic aortic stenosis had similar clinical outcomes with transcatheter aortic valve replacement (TAVR) vs surgical aortic valve replacement (SAVR) over 5 years of follow-up, with mortality rates of more than 50% in both groups.

To describe the long-term health status of surviving patients randomized to self-expanding TAVR vs SAVR.

This randomized clinical trial included patients at high surgical risk with severe aortic stenosis who completed a baseline Kansas City Cardiomyopathy Questionnaire (KCCQ) and were randomized to either self-expanding TAVR or SAVR from 45 US clinical sites. Patients were enrolled from February 2011 to September 2012. Analysis began May 2018 and ended June 2020.

Change in KCCQ and the 12-Item Short-Form Health Survey over 5 years, as assessed by repeated-measures analysis of covariance. Because there were significant interactions between access site and treatment for 1-month health status outcomes, all analyses were l summary score more than 60 (P = .61). In the noniliofemoral cohort, there were no significant health status differences at any time between TAVR and SAVR. find more Results were similar for individual KCCQ domains and the Short-Form Health Survey.

In high-risk patients with severe symptomatic aortic stenosis, there was an early health status benefit with self-expanding iliofemoral TAVR vs SAVR but no difference between groups in long-term health status. Although mortality at 5 years was high in this population, the majority of surviving patients continued to report reasonable health status.

Nail involvement is common in synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome, which has a strong association with quality of life in patients with SAPHO. Tofacitinib is an oral Janus kinase inhibitor that has been previously shown to be effective for nail psoriasis.

To assess the efficacy and safety of tofacitinib for the treatment of nail involvement in SAPHO syndrome.

Participants received tofacitinib, 5 mg, twice daily, for 12 weeks.

This open-label, single-arm, prospective pilot study included 13 patients with SAPHO syndrome accompanied by nail lesions and active palmoplantar pustulosis who were recruited from Peking Union Medical College Hospital from September 2019 to December 2019. Follow-up was completed in March 2020. Analysis began March 2020.

The primary end point was the percentage of the change from baseline in Nail Psoriasis Severity Index scores at week 12. Secondary end points included the percentage of the change from baseline in Palmoplantar Psoriasis Areaedian, -8 mm/h [IQR, -4 mm/h to -11 mm/h]; P < .001) and high-sensitivity C-reactive protein levels (median, -1.6 [IQR, -0.3 to -4.1]; P = .01). No severe adverse events were observed.

In this pilot study, tofacitinib yielded significant remission of nail lesions and palmoplantar psoriasis accompanied by an improvement in quality of life in patients with SAPHO syndrome. Additional follow-up studies to evaluate the long-term efficacy and safety of tofacitinib for nail involvement in SAPHO syndrome are warranted.

Considering the high risk of transmission of the virus in dental environments and the specificities in clinical practice, COVID-19 posed immediate challenges for dental care and education. Due to the need to establish infection prevention and control guidance in dental health settings to enable a safe clinical practice, this review aims to list the challenges and perspectives in managing dental care in services and schools. This review employed materials collected from PubMed and the main guidelines and studies on the novel coronavirus to provide an overview of the clinical procedures and decisions made by health care personnel in dental offices and dental schools. We expect the COVID-19 scenario to promote significant changes in clinical practice and dental education; dentists should seek specific and particular regulations for dental practice established by their state or country. Biosafety checklists are strongly recommended for appointments at dental services and face-to-face activities in dental schools.
This study aimed to determine serum and salivary levels of neutrophil gelatinase-associated lipocalin (NGAL) and evaluate NGAL correlation with key anti-interleukin 10 (IL-10) and pro-inflammatory (IL-1β) cytokines in different severities of periodontal diseases. We also calculated the systemic inflammation using the periodontal inflamed surface area (PISA) to evaluate its correlation with NGAL in the study groups.

Eighty systemically healthy and non-smoking individuals were separated into four groups of 20 clinically healthy (Group 1), gingivitis (Group 2), stage I generalized periodontitis (Group 3, Grade A), and stage III generalized periodontitis (Group 4, Grade A). Sociodemographic characteristics and periodontal parameters were recorded, and PISA was calculated. The serum and salivary levels of interleukin (IL)-1β, IL-10, and NGAL were determined using the enzyme-linked immunosorbent assay (ELISA).

We observed a significant increase in serum and salivary NGAL levels from healthy to periodontitis gfinding is supported by the higher serum and salivary cytokines/mediators levels in the gingivitis group than in stage I periodontitis group. Serum and salivary NGAL levels increased proportionally to disease severity and PISA. NGAL seems to play a role in the pathogenesis of periodontal disease, within the limitation of our study.
This study analyzed the effect of ionizing radiation on bone microarchitecture and biomechanical properties in the bone tissue surrounding a dental implant.

Twenty rabbits received three dental morse taper junction implants one in the left tibia and two in the right tibia. The animals were randomized into two groups the nonirradiated group (control group) and the irradiated group, which received 30 Gy in a single dose 2 weeks after the implant procedure. Four weeks after the implant procedure, the animals were sacrificed, and the implant/bone specimens were used for each experiment. The specimens (n=10) of the right tibia were examined by microcomputed tomography to measure the cortical volume (CtV, mm3), cortical thickness (CtTh, mm) and porosity (CtPo, %). The other specimens (n=10) were examined by dynamic indentation to measure the elastic modulus (E, GPa) and Vickers hardness (VHN, N/mm2) in the bone. The specimens of the left tibia (n=10) were subjected to pull-out tests to calculate the failure load (N), displacement (mm) up to the failure point and interface stiffness (N/mm).
