alid and reliable in assessing ROM in asymptomatic participants and patients with chronic neck pain and radial fracture. For the remaining outcomes, evidence is limited to draw a robust conclusion. Future studies are recommended to test VR psychometric properties in different patients' population using a rigor research methodology.
Solitary fibrous tumor (SFT) is a rare mesenchymal tumor with an intermediate tendency to metastasize. Meningeal hemangiopericytoma (HPC), arising in the meningeal membranes, also is considered an SFT. Although SFT is assumed to show an unpredictable behavior, the authors defined some factors associated with its aggressive behavior.

This retrospective study was based on the medical records of 81 SFT patients treated surgically, with the median follow-up period of 59 months. The patients were assigned to three histopathologic groups based on the 2016 WHO classification group 1 (SFT, 29 patients), group 2 (cellular SFT/hemangiopericytoma [HPC], 27 patients), and group 3 (malignant SFT/anaplastic HPC, 25 patients).

The SFT histopathologic classification was associated with distant metastasis (DM) (p = 0.007). The multivariate analysis showed that cellular SFT had an independent impact on DM (odds ratio [OR] = 25.42; p = 0.006). Tumor diameter larger than 7.25cm was correlated with DM (p = 0.010) and the patient's disease-specific death (DSD) (p = 0.007). A 1-cm increase in tumor diameter enhanced the likelihood of metastasis by 1.26 (OR = 1.26; 95% confidence interval [CI], 1.05-1.53). Tumors originating from the central nervous system (CNS) showed a greater tendency toward local recurrence (LR) (p = 0.039) and DM (p = 0.05). Radiotherapy had no association with LR, DM, or DSD. The 10-year disease-specific survival rate was 82.7%.

Tumor size and histopathologic diagnosis are the predictors of SFT's aggressive behavior. Cellular SFTs behave as aggressively as the malignant form of the tumor. A SFT grading based on SFT cellularity would contribute to anticipation of its aggressive behavior.

Breast core needle biopsy (CNB) can obviate the need for breast surgery in patients with an unknown breast lesion; however, variation in compliance with this guideline may represent a disparity in health care and a surrogate measure of unnecessary surgery. We evaluated variation in breast CNB rates prior to initial breast cancer surgery.

We performed a retrospective analysis using Medicare claims from 2015 to 2017 to evaluate the proportion of patients who received a CNB within 6months prior to initial breast cancer surgery. Outlier practice pattern was defined as a preoperative CNB rate ≤ 70%. Logistic regression was used to evaluate surgeon characteristics associated with outlier practice pattern.

We identified 108,935 female patients who underwent initial breast cancer surgery performed by 3229 surgeons from July 2015 to June 2017. The mean CNB rate was 86.7%. A total of 7.7% of surgeons had a CNB performed prior to initial breast surgery ≤ 70% of the time, and 2.0% had a CNB performed ≤ 50% of the time. Outlier breast surgeons were associated with practicing in a micropolitan area (odds ratio [OR] 1.88, 95% confidence interval [CI] 1.29-2.73), in the South (OR 1.84, 95% CI 1.20-2.84) or West region (OR 1.78, 95% CI 1.11-2.86), > 20years in practice (OR 1.52, 95% CI 1.09-2.11), and low breast cancer surgery volume (< 30 cases in the study period; OR 4.03, 95% CI 2.75-5.90).

Marked variation exists in whether a breast core biopsy is performed prior to initial breast surgery, which may represent unnecessary surgery on individual patients. Providing surgeon-specific feedback on guideline compliance may reduce unwarranted variation.

To establish hospital-based surveillance to identify cases of rotavirus (RV) among children <5 y of age hospitalized for acute gastroenteritis (AGE) and to determine the burden and profile of circulating RV genotypes in the region.

This study was conducted at a tertiary level hospital in Bijnor district of western Uttar Pradesh, India from January 2018 to January 2020. The duly filled case reporting forms and specimens of all the enrolled children were transported in cold chain to the referral laboratory at Christian Medical College (CMC), Vellore on a monthly basis for testing and storage of stool samples as well as data entry and analysis.

A total of 1055 under-5 children admitted with AGE, were enrolled. Proper stool specimens were collected from 932 children. Rotavirus was found positive in 368 (39.5%) stool specimens. Marked seasonality was observed in RV-positive cases with the highest incidence was noticed during winter months. The 0-11 mo age group had the highest incidence of RV-GE followed by 12-23 mo. G1 (42.08%) was the most frequent G-type whereas G1P[8] (26.23%) was the commonest circulating genotype.

The study confirms a significant burden of RV among AGE cases in young children in western Uttar Pradesh. The findings of the study may serve as useful baseline information to the Government of India for assessing vaccine performance after its introduction in the national immunization programmes.

To identify the burden of rotavirus acute gastroenteritis (AGE) and the genotypes presenting in the authors' area in the period after introduction of rotavirus vaccine in Universal Immunization Programme (UIP).

Children aged less than 5 y and presenting to hospital for the treatment of AGE were enrolled into the study from January 2016 to June 2019. Clinical details including age, gender, extent of illness, number of stools, concomitant vomiting and fever, grade of dehydration, and associated illness were recorded. Stool samples were tested for rotavirus using a commercially available ELISA Kit. Genotyping was performed for the rotavirus antigen-positive samples.

Rotavirus positive AGE was seen in 14.2% of the children. High burden of rotavirus gastroenteritis was seen in the age group of 6-23 mo and more cases were observed from December to February months. In our region the prevalent rotavirus genotypes in positive samples are G3 and G1 in G-typing, P[8] and P[4] in P-typing, respectively. G3P[8] and G1P[8] are the most prevalent genotypes identified in our area with a frequency of 35.1% and 25.9%, respectively. Almost all the cases (97.7%) got discharged and only one patient has died.

The findings conclude a declining trend in the rotavirus positive AGE cases in the authors' area after introduction of Rotavac vaccine in the UIP.

Several SARS-CoV-2 vaccine compositions use nanotechnology-enabled formulations. A silver lining of the COVID-19 pandemic is that the fast-tracked vaccine development for SARS-CoV-2 has advanced the clinical translation pathway for nanomedicine drug delivery systems. The laboratory science of lipid-based nanoparticles was ready and rose to the clinical challenge of rapid vaccine development. The successful development and fast tracking of SARS-CoV-2 nanomedicine vaccines has exciting implications for the future of nanotechnology-enabled drug and gene delivery; it demonstrates that nanomedicine is necessary and critical to the successful delivery of advanced molecular therapeutics such as nucleic acids, it is establishing the precedent of safety and the population effect of phase four clinical trials, and it is laying the foundation for the clinical translation of more complex, non-lipid nanomedicines. The development, fast-tracking, and approval of SARS-CoV-2 nanotechnology-based vaccines has transformed the seemingly daunting challenges for clinically translating nanomedicines into measurable hurdles that can be overcome. Due to the tremendous scientific achievements that have occurred in response to the COVID-19 pandemic, years, perhaps even decades, have been streamlined for certain translational nanomedicines.The majority of area burned by wildfire are located in Siberia. Mainly low-intensity surface fires occur in larch forests, whereas in evergreen forests both surface and crown fires are observed. Warming has led to an increase in the frequency and area of wildfires that have reached the Arctic Ocean shore. However, wildfires are the most important factor in taiga dynamics; larch and Scots pine have evolved under conditions of periodic forest fires, thereby gaining a competitive advantage over non-fire adapted species; in the permafrost zone, periodic fires are a prerequisite for the dominance of larch. Wildfires support ecosystem health, biodiversity, and conservation; periodic wildfires decrease the danger of catastrophic wildfires. With an amplified rate of increase in fires, it is necessary to focus fire suppression on areas of high social, natural, and economic value, while allowing a greater number of wildfires to burn in the vast Siberian forest landscapes.
Although many biologic therapies are effective for clearing skin of patients with psoriasis, some lose effectiveness over time. This phase2 open-label extension (OLE) trial was designed to investigate the long-term safety and efficacy of risankizumab.

In the phase 2, double-blind, active comparator, predecessor trial (NCT02054481), patients with moderate-to-severe chronic plaque psoriasis were treated for 24weeks with subcutaneous (SC) risankizumab or ustekinumab, followed by a 24-week follow-up without treatment administration. Patients could enroll in the OLE (NCT02203851) when they experienced loss of treatment response (< 50% improvement in the Psoriasis Area Severity Index [PASI 50]) during follow-up) or at the end of follow-up if treatment response was ongoing. In the OLE, patients were treated every 12weeks for at least 48weeks with SC risankizumab 90or 180mg, beginning at week 12 (OLE visit 2), if the patient had not achieved PASI 90. Rimiducid chemical structure Efficacy endpoints included the proportions of patients who achieved PASI 50/75/90/100 and static Physician's Global Assessment (sPGA) of clear or almost clear skin at week48 (sPGA 0/1; OLE visit 5).

Of the 110 enrolled patients, 99 (90.0%) completed the OLE. No patients discontinued the study because of adverse events. At week 48, 74.1% of patients achieved PASI90, whereas 98.1, 91.7, 53.7, and 67.6% achieved PASI 50/75/100 and sPGA0/1, respectively. All efficacy results were consistent or slightly increased at OLE week 48 compared with week 12. No new safety findings were observed.

Risankizumab treatment was well tolerated with sustained clinical efficacy for at least 48weeks.
