Collectively, the present study suggests that the inhibition of oxidative stress, inflammatory and TGF-β/smad signalling might be involved in the observed anti-fibrotic benefits of FA against silica-induced PF in mice.Alpha therapy provides an outstanding prospect in the treatment of recalcitrant and micrometastatic cancers. However, side effects on the normal tissues and organs (especially, kidneys) due to the release of daughter isotopes from α-emitters remain a bottleneck. In this work, calcium carbonate core-shell particles of different sizes were considered as isotope carriers for encapsulation of 225Ac (highly powerful alpha-emitter that generates 4 net alpha particle isotopes in a short decay chain) in order to achieve in vitro and in vivo retention of 225Ac and its daughter isotopes. According to the in vitro studies, the developed calcium carbonate core-shell particles were able to retain 225Ac and its daughter isotopes (221Fr and 213Bi) exhibited good stability in biological media and dose-dependent biocompatibility (over 30 d). The SPECT imaging demonstrated the size-dependent distribution of 225Ac-doped core-shell particles. Further, in vivo studies confirmed the high retention efficiency of calcium carbonate core-shell particles, which was demonstrated in normal Wistar rats (up to 10 d). Interestingly, the radioactivity accumulation in kidney and urine was significantly less for encapsulated 225Ac than in case of non-encapsulated form of 225Ac (225Ac conjugated with albumin), indicating the absence of radioisotope leakage from the developed particles. Thus, our study validates the application of 225Ac-doped core-shell particles to sequester α-emitter (225Ac) and its decay products in order to reduce their systemic toxicity during alpha therapy.Daily COVID-19 infection rates were examined before and after statewide school closure orders. Regression techniques were used to model changes in the number of confirmed cases and data was combined across states using meta analyses. School closures were found to have a significant impact on infection rates, and thus, may be considered a viable intervention to lower COVID-19 infection rates.

Hand hygiene is essential for infection prevention. This study aimed to find a suitable theoretical model and identify critical facilitators and barriers to explain hospital visitors' hand hygiene practice.

Visitors in 4 hospitals were observed and asked to give explanations for using or not using the hand rub dispenser. The written explanations of N = 838 participants were coded according to three theoretical models Theory of Planned Behavior, Health Action Process Approach (HAPA), and Theoretical Domains Framework (TDF).

Self-reported hand hygiene behavior differed from observed behavior, with 15.75% wrongly claiming to have cleaned their hands. Critical facilitators for hand hygiene were attitude toward the behavior,subjective norm, outcome expectancies, risk perception, planning, action control, knowledge and skills, motivation and goals, and social influences. Key barriers included perceived behavioral control; barriers and resources; memory, attention, and decision processes; and environmental context and resources.

Visitors' self-reported hand hygiene behavior is over-reported. Both HAPA and TDF were identified as suitable theoretical models for explaining visitor's hand hygiene practice. Future behavior change interventions should focus on (1) visibility and accessibility of cleaning products; (2) informing laypeople about their role regarding infection prevention; and (3) leveraging social influence processes.

The proportion of positive patients admitted to acute-care hospitals for reasons other than coronavirus disease-19 (COVID-19) is unknown. These patients potentially put other patients and healthcare workers at risk of infection.

The objective of this study was to define the proportion of asymptomatic patients admitted with severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). Secondary objectives were to define the positivity rate, reasons for admission, and the geographic distribution in the region.

Universal surveillance testing for SARS-CoV-2 was performed on patients admitted to this hospital over a 12-week period from April 9, 2020 to July 1, 2020. Positive patients were categorized as either symptomatic or asymptomatic as defined by the 11 criteria per the Centers for Disease Control and Prevention. The positivity rate, proportion with and without symptoms, reasons for admission, and geographic distribution in the region were recorded.

The positivity rate ranged from 0.8% to 6.2%. The proportion of asymptomatic patients with SARS-CoV-2 was 37%. Asymptomatic patients primarily presented to the hospital because of either trauma or labor. Some clusters in the region were identified of both symptomatic and asymptomatic patients.

The proportion of asymptomatic patients admitted with SARS-CoV-2 was significant. Identifying and isolating asymptomatic patients likely prevented exposure and development of hospital-acquired COVID-19 cases among healthcare workers and other patients, supporting the universal surveillance of all admitted patients.

Cas12 and Cas13 are CRISPR proteins that are efficient agents for diagnosis and combating single-stranded RNA (ssRNA) viruses. The programmability of these proteins paves the way for the detection and degradation of RNA viruses by targeting RNAs complementary to its CRISPR RNA (crRNA). Birinapant mw Approximately two-thirds of viruses causing diseases contain ssRNA genomes. The Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) has caused the outbreak of the coronavirus disease 2019 (COVID-19), which has infected more than 88 million people worldwide with near 2 million deaths since December 2019. Thus, accurate and rapid diagnostic and therapeutic tools are essential for early detection and treatment of this widespread infectious disease. For us, the CRISPR based platforms seem to be a plausible new approach for an accurate detection and treatment of SARS-CoV-2. In this review, we talk about Cas12 and Cas13 CRISPR systems and their applications in diagnosis and treatment of RNA virus mediated diseases. In continue, the SARS-CoV-2 pathogenicity, and its conventional diagnostics and antivirals will be discussed. Moreover, we highlight novel CRISPR based diagnostic platforms and therapies for COVID-19. We also discuss the challenges of diagnostic CRISPR based platforms as well as clarifying the proposed solution for high efficient selective in vivo delivery of CRISPR components into SARS-CoV-2-infected cells.

To present the results of Koyanagi-Snow-Hayashi urethroplasty in severe hypospadias repair.

From June 2015 to December 2019, 43 patients with severe hypospadias associated with curvature underwent Koyanagi- Snow-Hayashi urethroplasty. All patients were treated for the first time and by a single surgeon. Thirty-five patients included in this study presented a form of disorders of sex development. The age of the patients at surgery varied from 12 to 120 months (mean age 21 months ± 6 months). The median follow-up was 28 months (range, 5-65 months).

Functional and esthetic results were satisfactory with a straight and excellent appearance of the penis, without any complications in only ten patients (23%). While 30 of 43 patients (70 %) required additional procedures. Postoperative complications encountered in our patients were dominated by fistulas which were found in 17 of 43 patients (39.5%). Among them, 3 fistulas appeared in the penile shaft between 11 and 28 days and disappeared spontaneously. While proximal fistulas have been required surgical repair. Diverticulum seemed to be a significant complication of this technique, it was found in 4 of 43 (9%). This study also revealed the presence of a peculiar complication for this procedure, urethral meatus in the shape of fish lips.

The use of Koyanagi-Snow-Hayashi urethroplasty in severe hypospadias repair gives a complete penile straightening in all cases. However, Despite the modifications added by Snow and Hayashi to Koyanagi urethroplasty to improve the vascular supply of the flap, the rate of complications encountered with this technique remains high.

To determine the feasibility and perceived usefulness of a pre-residency urology boot camp for first and second year urology residents.

First and second year urology residents attended a multi-institutional boot camp in July 2019, which consisted of lectures, a hands-on practical, patient simulation session, and networking social event. Attendees completed a pre-course survey where they rated their comfort level in managing interpersonal, post-operative, and urology-specific scenarios on a Likert scale of 0-5. Participants completed follow-up surveys immediately and 6 months after the course regarding confidence in managing the same scenarios and the impact of boot camp on their training.

6 urology PGY1s (55%) and 5 PGY2s (45%) from 4 institutions attended the boot camp. On the precourse survey, PGY2s had higher average comfort scores compared to PGY1s for all post-operative scenarios besides hypotension but just 2 urology-specific scenarios, difficult Foley troubleshooting (4 vs 3, P < .01) and obstructing urolithiasis with urosepsis (3.6 vs 2.2, P = .05). Immediately after the course, 10 of 11 (91%) residents reported feeling better prepared to handle all scenarios. All participants reported they would recommend this training to other urology residents. Six months later, the majority of respondents reported using knowledge learned in boot camp on a daily basis. All agreed that it was a useful networking experience, and 63% had since contacted other residents they met at the course.

A pre-residency boot camp is both feasible and valuable for first- and second-year urology residents for gaining practical medical knowledge and professional networking.
