The ice bag and saltwater pack cause statistically greater cooling than the other materials tested. CONCLUSIONS This study does not support the clinical use of an enswell to provide short-duration cryotherapy treatments to facial tissue, as ice packs are more effective.CONTEXT The Y-Balance Test (YBT) and Star Excursion Balance Test (SEBT) are commonly used to detect deficits in dynamic postural control. There is a lack of literature on the differences in reach distances and efficiency of the tests. OBJECTIVE To compare the reach distances of the YBT and SEBT. An additional aim was to compare the time necessary to administer the 2 tests and utilize a discrete event simulation to determine the number of participants who could be screened within different scenarios. DESIGN Cross-sectional. Laboratory Patients Twenty-four physically active individuals between the ages of 18-35 years volunteered to participate in this study (M/F 11/13; age 22.78 [2.63] y, height 68.22 [4.32] cm, mass 173.27 [10.96] kg). INTERVENTION The participants reported to the laboratory on one occasion and performed the YBT and SEBT. The anterior, posteromedial, and posterolateral reach distances were recorded for each test. In addition, the time to administer each test was recorded in seconds. MAIN OUTCOME MEASURES The average reach distances and time for each test were used for analysis. Paired t tests were utilized to compare the reach distances and time to administer the 2 tests. A discrete event simulation was used to determine how many participants could be screened using each test. RESULTS The anterior reach for the SEBT (64.52% [6.07%]) was significantly greater than the YBT (61.66% [6.37%]; P less then .01). The administration time for the YBT (512.42 [123.97] s) was significantly longer than the administration time for the SEBT (364.96 [69.46] s; P less then .01). The discrete event simulation revealed more participants could be screened using the SEBT when compared with the YBT for every situation. CONCLUSION Scores on the anterior reach of the SEBT are larger when compared with the YBT. The discrete event simulation can successfully be used to determine how many participants could be screened with a certain amount of resources given the use of a specific test.BACKGROUND SARS-CoV-2 (severe acute respiratory coronavirus 2) was spreading rapidly in South Korea at the end of February 2020 following its initial outbreak in China, making Korea the new center of global attention. The role of social media amid the current coronavirus disease (COVID-19) pandemic has often been criticized, but little systematic research has been conducted on this issue. Social media functions as a convenient source of information in pandemic situations. OBJECTIVE Few infodemiology studies have applied network analysis in conjunction with content analysis. This study investigates information transmission networks and news-sharing behaviors regarding COVID-19 on Twitter in Korea. The real time aggregation of social media data can serve as a starting point for designing strategic messages for health campaigns and establishing an effective communication system during this outbreak. METHODS Korean COVID-19-related Twitter data were collected on February 29, 2020. Our final sample comprised of 43Journal of Medical Internet Research (http//www.jmir.org), 05.05.2020.The coronavirus disease 2019 (COVID-19) outbreak has required institutions to rapidly adapt to changing public health circumstances. The Centers for Disease Control and Prevention has encouraged health care facilities to explore novel health care delivery modes. However, many institutions may not be prepared to begin offering digital health and telehealth services. Chatbots are one digital health tool that can help evolve triage and screening processes in a scalable manner. Here, we present a decision-making and implementation framework for deploying COVID-19 screening chatbots at pediatric health care facilities. ©Juan Espinoza, Kelly Crown, Omkar Kulkarni. Originally published in JMIR Public Health and Surveillance (http//publichealth.jmir.org), 30.04.2020.The social motivation hypothesis posits that people with autism spectrum disorder (ASD) find social stimuli less rewarding and are therefore less motivated towards social interaction than people with neuro-typical development (TD). However, the less rewarding social stimuli characteristics during social interaction for people with ASD are largely unknown. The contingent positive responsiveness of others relevant to self-action motivates the early development of social interaction, thus representing a social reward. As individuals with ASD often exhibit atypical responses to self-relevant stimuli in their early life, we hypothesized that the self-relevant responses of others are less rewarding for individuals with ASD. To test this hypothesis, we conducted a functional magnetic resonance imaging study using a social contingency task. During the task, the participants attempted to make the audience laugh by telling funny jokes and thus activating the anterior rostral medial prefrontal cortex (arMPFC) of TD individuals (Sumiya et al., 2017). We explicitly predicted that the atypical activation of the arMPFC is related to the reduced reward value of self-relevant responses to others in individuals with ASD. Thirty-one adults with ASD and 24 age- and intelligence quotient-matched TD adults participated in the study. Participants with ASD reported significantly lower pleasure after the audience's responses to their own actions than those in the TD group. Correspondingly, the self-related activation of the arMPFC, defined by the results of our previous study, was attenuated in the ASD group compared to the TD group. The present findings indicate that weak self-relevant outcome processing mediated by the arMPFC of individuals with ASD dampens the rewarding nature of social interaction. Nucleotide-binding oligomerization domain-Like Receptor with a Pyrin domain 3 (NLRP3) inflammasome was emerged as a marker of metabolic dysregulation. We revealed that age-related Sirtuin-1 (SIRT1) modulates cardiac metabolism that medicated inflammatory response during ischemia and reperfusion (I/R) stress. We hypothesize that SIRT1 attenuates NLRP3 inflammasome-dependent inflammation and pyroptosis during myocardial I/R through metabolic modulation. C57BL/6J wild type (WT) mice, inducible cardiomyocyte specific SIRT1 knockout (icSIRT1 KO) and inducible cardiomyocyte specific PDH E1α knockout (icPDH E1α KO) mice were subjected to ligation and release of left anterior descending coronary artery for in vivo regional I/R models. The echocardiography measurement demonstrated that SIRT1 agonist SRT1720 (30 μg/g) improved cardiac systolic function during 45 min of ischemia and 6 h of reperfusion in C57BL/6J WT mice. The biochemical analysis showed that I/R triggered activation of cardiac pyruvate dehydrogenase (PDH), while SIRT1 agonist SRT1720 inhibited I/R-induced PDH activity and reduced production of reactive oxygen species (ROS) during myocardial I/R. Moreover, SRT1720 regulates PDH-related glucose oxidative metabolism to reduce NLRP3 inflammasome activation and pyroptosis in an Akt signaling dependent manner during I/R. Furthermore, an impaired Akt signaling was observed in icSIRT1 KO versus SIRT1fox/flox mice under I/R stress. Intriguingly, we observed lower levels of ROS generation, decreased NLRP3 levels and less pyroptosis occurred in the icPDH E1α KO versus PDH E1αflox/flox hearts during I/R. Taken together, the results indicate that SIRT1 agonism can inhibit activation of NLRP3 inflammasome via Akt-dependent metabolic regulation during ischemic insults by I/R. V.BACKGROUND Focal cortical dysplasia (FCD) is a localized cortical malformation and considerable morphological overlap exists between FCD IIB and neurological lesions associated with Tuberous sclerosis complex (TSC). Abnormal mTOR pathway secondary to somatic mTOR mutation and TSC gene mutation linked to PI3K/AKT/mTOR pathway have supported the hypothesis of common pathogenesis involved. Role of converging pathway, viz. Wnt/β-Catenin and mTOR is unknown in FCD. We aimed to analyse FCD IIB for TSC1/TSC2 mutations, immunoreactivity of hamartin, tuberin, mTOR and Wnt signalling cascades, and stem cell markers. MATERIALS AND METHODS Sixteen FCD IIB cases were retrieved along with 16 FCD IIA cases for comparison. Immunohistochemistry was performed for tuberin, hamartin, mTOR pathway markers, markers of stem cell phenotype, and Wnt pathway markers. Mutation analysis for TSC1 and TSC2 was performed by sequencing in 9 FCD cases. RESULTS All FCD cases showed preserved hamartin and tuberin immunoreactivity. Aberrant immd diagnostic technique since conventional sanger sequencing often fails to detect low-allele frequency variants involved in mTOR/TSC pathway genes, commonly found in FCD. BACKGROUND Cell-mediated immunity including T-cells (T helper and cytotoxic) plays an essential role in efficient antiviral responses against coronavirus disease-2019 (COVID-19). Therefore, in this study, we evaluated the ratio and expression of CD4 and CD8 markers in COVID-19 patients to clarify the immune characterizations of CD4 and CD8 T-cells in COVID-19 patients. METHODS Peripheral blood samples of 25 COVID-19 patients and 25 normal individuals with similar age and sex as the control group were collected. White blood cells, platelets, and lymphocytes were counted and CD4 and CD8 T lymphocytes were evaluated by flow cytometry. RESULTS The number of white blood cells, lymphocytes, and platelets were reduced significantly in COVID-19 patients (P  0.05); however, the CD8 MFI increased significantly in COVID-19 infected patients (P  less then  0.05). CONCLUSION Although, there is no significant difference in the ratio of CD4 to CD8 between two groups, the expression level of CD8 in COVID-19 patients was significantly higher than the normal individuals. This result suggested that the cellular immune responses triggered by COVID-19 infection were developed through overexpression of CD8 and hyperactivation of cytotoxic T lymphocytes. BACKGROUND Whether risk-reducing salpingo-oophorectomy (RRSO) in BRCA1/2 carriers reduces the breast cancer (BC) risk is conflicting, potentially due to methodological issues of prior analysis. We analysed the association between premenopausal RRSO and BC risk in BRCA1/2 carriers after adjusting for potential biases. METHODS We analysed data from 444 BRCA1 and 409 BRCA2 carriers under age 51 with no cancer prior to genetic testing or during first 6 months of surveillance (to avoid cancer-induced testing bias and prevalent-cancer bias). STF-083010 Observation started 6 months after genetic testing (to avoid event-free time bias), until BC diagnosis, risk-reducing mastectomy (RRM) or death. A multistate model with four states (non-RRSO, RRSO, RRM and BC) and five transitions was fitted to characterise outcomes and to calculate the BC risk reduction after premenopausal RRSO (before age 51). A systematic review was performed to assess the association between premenopausal RRSO and BC. RESULTS During a mean follow-up of 4.3 years, 96 women (11.3%) developed BC (54 BRCA1, 42 BRCA2). The risk of BC after premenopausal RRSO decreased significantly in BRCA1 carriers (hazard ratio (HR) = 0.45 [95% confidence interval (CI)0.22-0.92]), but was not conclusive in BRCA2 carriers (HR = 0.77 [95%CI0.35-1.67]). The systematic review suggested that premenopausal RRSO is associated with a decrease of BC risk in both BRCA1 and BRCA2 carriers. CONCLUSIONS Premenopausal RRSO was associated with BC risk reduction in BRCA1 carriers, which can help guide cancer risk-reducing strategies in this population. Longer follow-up and larger sample size may be needed to estimate the potential benefit in BRCA2 carriers.
