st of our knowledge. The results suggest that (a) SDDRO can substantially improve the FLASH-dose rate coverage (e.g., in terms of dose rate volume histogram) compared to IMPT for the purpose of normal tissue sparing while preserving the dose distribution and (b) the combination of hypofractionation and multiple beams can further considerably improve the SDDRO plan quality in terms of both dose and dose rate distribution.
We have developed a joint dose and dose rate optimization method for FLASH proton RT, namely SDDRO, which is first-of-its-kind to the best of our knowledge. The results suggest that (a) SDDRO can substantially improve the FLASH-dose rate coverage (e.g., in terms of dose rate volume histogram) compared to IMPT for the purpose of normal tissue sparing while preserving the dose distribution and (b) the combination of hypofractionation and multiple beams can further considerably improve the SDDRO plan quality in terms of both dose and dose rate distribution.
This study aimed to investigate the value of high-flow nasal cannula (HNFC) oxygen therapy in treating patients with severe novel coronavirus pneumonia (COVID-19).

The clinical data of 22 patients with severe COVID-19 were collected. The heart rate (HR), respiratory rate (RR) and oxygenation index (PO
/FiO
) at 0, 6, 24 and 72hours after treatment were compared between the HFNC oxygen therapy group and the conventional oxygen therapy (COT) group. In addition, the white blood cell (WBC) count, lymphocyte (L) count, C-reactive protein (CRP) and procalcitonin (PCT) were compared before and at 72hours after oxygen therapy treatment.

The differences at 0hours between the two groups were not statistically significant. Compared with COT group,in the HFNC oxygen therapy group, HR, RR and PaO
/FiO
were better at 6hours after treatment, PaO
/FiO
was better at 24 and 72hours. After 72hours, L and CRP had improved in the HFNC oxygen therapy group compared with the COT group, but the differences in WBC and PCT were not statistically significant. The length of stay in the intensive care unit (ICU) and the total length of hospitalization was shorter in the HFNC oxygen therapy group than in the COT group.

Compared with COT, early application of HFNC oxygen therapy in patients with severe COVID-19 can improve oxygenation and RR, and HFNC oxygen therapy can improve the infection indexes of patients and reduce the length of stay in the ICU of patients. Therefore, it has high clinical application value.

Noninvasive screening for cardiac allograft vasculopathy (CAV) instead of invasive coronary angiography (ICA) within the first 3 to 5years after heart transplantation (HTx) is controversial. We evaluated a strategy of intravascular ultrasound (IVUS)-guided conversion to early noninvasive screening post-HTx.

A single-center study of 103 consecutive HTx recipients from 2008 to 2018 undergoing ICA at 1year post-HTx. Of 88 patients with normal 1-year ICA, sixty-six patients underwent IVUS examination for risk stratification by maximal intimal thickness (MIT) into (i) low-risk group (MIT<0.5mm) (n=41, 62%) followed noninvasively versus (ii) high-risk group (MIT≥0.5mm) (n=25, 38%) followed with yearly ICA. Both groups underwent ICA at year 5 post-HTx. We evaluated a combined endpoint of angiographic CAV and death at 5-year follow-up post-HTx.

Median (IQR) age was 51 (33-60)years, and 62% were male. Follow-up was 1443 (1125-1456)days. Survival free from angiographic CAV (Kaplan-Meier) differed significantly between groups (log-rank p<.0001). A subgroup of 27 patients completed ICA at year 5, and the proportion of angiographic CAV was significantly lower in low-risk patients (p<.0001).

IVUS-guided selection for early noninvasive CAV screening appears to be safe and holds promise as a novel strategy for early risk stratification and CAV surveillance post-HTx.

We have seen several incidences of catastrophic bleeding in patients with advanced oropharyngeal squamous cell carcinoma treated nonoperatively. Aside from advanced disease, these patients have not had traditional risk factors for major hemorrhage.

Retrospective chart review.

Patients treated nonoperatively for oropharyngeal squamous cell carcinoma were compared to determine characteristics that may predisposed to bleeding. Five patients with bleeding were identified and compared with a cohort of stage- and treatment-matched patients without bleeding. Blinded imaging review was performed to characterize the tumor site and its relationship to vasculature using standardized systems.

Comparing the bleeder versus nonbleeder groups pre-treatment, the bleeder group had larger tumors (15.4 vs. 8.3 cm
), greater rates of parapharyngeal fat effacement (80% vs. 20%), and always involved the facial artery. Post-treatment, endophytic ulcerated tumor beds occurred in 100% of bleeders versus 0% of nonbleeders.

Catastrophic oropharyngeal bleeding may be encountered after cytoreductive therapy. Large deeply invasive tumors seem to set the necessary circumstances. Rapid vascular control with interventional radiology has been largely effective therapy.

There is currently no disease-modifying drug for osteoarthritis (OA), and some safety concerns have been identified about the leading traditional drugs. Therefore, research efforts have focused on alternatives such as supplementation with collagen derivatives. Selleck Molidustat The objective of this scoping review is to examine the extent, range, and nature of research, and to summarize and disseminate research findings on the effects of collagen derivatives in OA and cartilage repair. The purpose is to identify gaps in the current body of evidence in order to further help progress research in this setting.

The databases Medline, Scopus, CENTRAL, TOXLINE, and CDSR were comprehensively searched from inception to search date. After studies selection against eligibility criteria, following recommended methods, data were charted from the retrieved articles and these were subsequently synthesized. Numerical and graphical descriptive statistical methods were used to show trends in publications and geographical distribution of studies.
