Vaccines provide substantial indirect protection of unvaccinated children and adults through community protection. This protection has sometimes been greater than the direct impact of vaccines on disease. Abstract The direct impact of vaccines on children is well described, but the major public health impact of indirect protection provided to the community by vaccines is underappreciated. Community protection occurs when vaccinated persons block the chain of transmission, protecting undervaccinated or unvaccinated susceptible community members by preventing exposure and limiting the spread of the pathogen through the community. Substantial declines in disease incidence have occurred shortly after implementing new childhood vaccines, including declines among vaccine-ineligible children, adolescents, and adults. Protection of susceptible community members depends on maintaining high vaccination rates. Improved recognition of community protection will strengthen childhood vaccination strategies that will protect our communities into the future.

This research examined how self-efficacy, collective efficacy, and professional development compared between core content and special education middle school teachers working with middle school students in reading comprehension and fluency. Accordingly, no statistically significant difference in teacher self-efficacy between core content and special education teachers was discovered based on the ANOVA analysis results. An analysis of professional development and collective teacher efficacy showed mixed results with a negative relationship predicted between increased professional development hours for core content teachers. A predicted positive relationship existed with the number of professional development hours increasing for special education teachers. There was no statistically significant difference between core content and special education teachers’ numbers of professional development hours identified as low, medium, or high. The chi statistic showed that both populations of teachers had insufficient training.

Background Scant data are available about global patterns of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread and global epidemiology of early confirmed cases of COVID-19 outside mainland China. We describe the global spread of SARS-CoV-2 and characteristics of COVID-19 cases and clusters before the characterisation of COVID-19 as a pandemic. Cases of COVID-19 reported between Dec 31, 2019, and March 10, 2020 (ie, the prepandemic period), were identified daily from official websites, press releases, press conference transcripts, and social media feeds of national ministries of health or other government agencies. Case characteristics, travel history, and exposures to other cases were abstracted. Countries with at least one case were classified as affected. Early cases were defined as those among the first 100 cases reported from each country. Later cases were defined as those after the first 100 cases. We analysed reported travel to affected countries among the first case reported from each country outside mainland China, demographic and exposure characteristics among cases with age or sex information, and cluster frequencies and sizes by transmission settings. Among the first case reported from each of 99 affected countries outside of mainland China, 75 (76%) had recent travel to affected countries; 60 (61%) had travelled to China, Italy, or Iran. Among 1200 cases with age or sex information, 874 (73%) were early cases. Among 762 early cases with age information, the median age was 51 years (IQR 35–63); 25 (3%) of 762 early cases occurred in children younger than 18 years. Overall, 21 (2%) of 1200 cases were in health-care workers and none were in pregnant women. 101 clusters were identified, of which the most commonly identified transmission setting was households (76 [75%]; mean 2·6 cases per cluster [range 2–7]), followed by non-health-care occupational settings (14 [14%]; mean 4·3 cases per cluster [2–14]), and community gatherings (11 [11%]; mean 14·2 cases per cluster [4–36]). Cases with travel links to China, Italy, or Iran accounted for almost two-thirds of the first reported COVID-19 cases from affected countries. Among cases with age information available, most were among adults aged 18 years and older. Although there were many clusters of household transmission among early cases, clusters in occupational or community settings tended to be larger, supporting a possible role for physical distancing to slow the progression of SARS-CoV-2 spread. None.

The impact of convection on electrochemical performance, performance distribution, and local pressure drop is investigated via simple strip cell architecture, a cell with a single straight channel. Various channel depths (0.25, 0.5, 1, 2.5 mm) and flow rates (10–50 mL min−1 cm−2) are employed to induce a wide range of electrolyte velocities within the channel and electrode. Computational flow simulation is utilized to assess velocity and pressure distributions; experimentally measured in situ current distribution is quantified for the cell. Although the total current in the cell is directly proportional to electrolyte velocity in the electrode, there is no correlation detected between electrolyte velocity in the channel and the total current. It is found that the maximum achievable current is limited by diffusion mass transport resistance between the liquid electrolyte and the electrode surfaces at the pore level. Low electrolyte velocity induces large current gradients from inlet to outlet; conversely, high electrolyte velocity exhibits relatively uniform current distribution down the channel. Large current gradients are attributed to local concentration depletion in the electrode since the velocity distribution down the channel is uniform. Shallow channel configurations are observed to successfully compromise between convective flow in the electrode and the overall pressure drop.

In today's ever-changing and trend-focused climate, educators often are tempted to jump on the newest craze to hit the educational scene. Sometimes, after closer examination, it becomes clear that the new instructional strategies are more than short-term trends; in fact, they may be an idea that feels familiar. This is the case with project-based learning (PBL), which is more than a new \"trend\" for family and consumer science (FCS) education. It is an instructional strategy that has existed as a consistent standard and practice throughout the history of FCS. The application of PBL in FCS can be traced back to the practices of Ellen Swallow Richards who was known for seeking ways to apply scientific and management principles in real-world settings (Deaton et al., 2018). Although Richards used different nomenclature to describe PBL, she was seeking authentic opportunities for students to think critically and solve problems related to the content of FCS-the same authentic opportunities that form the foundation and essential components of effective PBL. FCS is a global discipline and profession that extends into multiple application settings (Palombit, 2019). With an audience of more than 5 million FCS students nationwide (AAFCS, 2019), FCS teachers have an amazing opportunity to have an impact on students' abilities to think critically, work cooperatively, and solve problems effectively through proper implementation of PBL instructional strategies and teaching methodologies.

The pace of global progress must increase if the Global Vaccine Action Plan (GVAP) goals are to be achieved by 2020. We administered a two-phase survey to key immunization stakeholders to assess the utility and application of GVAP, including how it has impacted country immunization programs, and to find ways to strengthen the next 10-year plan. For the Phase I survey, an online questionnaire was sent to global immunization stakeholders in summer 2017. The Phase II survey was sent to regional and national immunization stakeholders in summer 2018, including WHO Regional Advisors on Immunization, Expanded Programme on Immunization managers, and WHO and UNICEF country representatives from 20 countries. Countries were selected based on improvements (10) versus decreases (10) in DTP3 coverage from 2010 to 2016. Global immunization stakeholders (n = 38) cite global progress in improving vaccine delivery (88%) and engaging civil society organizations as advocates for vaccines (83%). Among regional and national immunization stakeholders (n = 58), 70% indicated reaching mobile and underserved populations with vaccination activities as a major challenge. The top ranked activities for helping country programs achieve progress toward GVAP goals include improved monitoring of vaccination coverage and upgrading disease surveillance systems. Most respondents (96%) indicated GVAP as useful for determining immunization priorities and 95% were supportive of a post-2020 GVAP strategy. Immunization stakeholders see GVAP as a useful tool, and there is cause for excitement as the global immunization community looks toward the next decade of vaccines. The next 10-year plan should attempt to increase political will, align immunization activities with other health system agendas, and address important issues like reaching mobile/migrant populations and improving data reporting systems.

Over the past two decades the Standards for Technological Literacy (STL) (ITEEA, 2000) have challenged educators to search for strategies to implement and address improvements in technological literacy rates among P-12 students. Capobianco, Yu, and French (2014) acknowledged “the integration of engineering practices in the science classroom as early as grade one shows potential in fostering and sustaining student interest, participation, and self-concept in engineering and science” (p. 275). The updated Standards for Technological and Engineering Literacy (STEL) (ITEEA, 2020) are organized into three STEL structural branches that combine to create a pedagogical and domain knowledge configuration for technology and engineering teachers (ITEEA, 2020). Although the three STEL organizational branches are at the forefront, this study attempts to focus on and identify the relationship between the practices surrounding the eight core STEL standards: systems thinking, creativity, making and doing, critical thinking, optimism, collaboration, communication, and attention to ethics. These specific practices are designed for the integration of STEM in the classroom and may be advantageous toward promoting technological and engineering literacy through tinkering and take-apart teaching methodologies. Acknowledging that the teacher may be the STEM integration decision maker in the classroom, this study attempts to discern the link between STEL, tinkering and take-apart teaching methodologies, and pre-service elementary teacher candidates’ self-efficacy in the STEM disciplines of technology and engineering education as well as providing implications for future practice in the elementary classroom.

Objectives: Primary urethral carcinoma (PUC) is rare, accounting for <1% of genitourinary malignancies. Current knowledge regarding is founded upon tertiary care centers reporting their experiences. We aim to identify factors predictive of outcomes using a nationwide registry database. Materials and Methods: The Surveillance, Epidemiology, and End Results-18 registries database was queried for cases of PUC ranging between 2004 and 2010. To identify PUC cases, ICD-O site code C68.0 was used as a filter, hence identifying PUC with histologic subtypes including urothelial carcinoma (UC), squamous cell carcinoma (SCC), and adenocarcinoma (AC). Tumor characteristics were compared using log-rank analysis, and survival outcomes were compared using Cox proportional hazards models. Results: A total of 419 PUC cases were identified, 250 (59.7%) male and 169 (40.3%) female patients. The most common histology in men was UC (134, 53.6%), followed by SCC (87, 34.8%) and AC (29, 11.6%). The most common histology in women was AC (79, 46.7%), followed by SCC (43, 25.4%) and UC (42, 24.9%). Log-rank analysis illustrated significant difference in cancer-specific survival (CSS) for T-stage, N-stage, M-stage, and stage of PUC with all histological variants combined (P < 0.001). Multivariate Cox proportional hazards model demonstrated that stage and age were significant for survival, with a risk ratio of 1.033 (95% confidence interval [CI], 1.020-1.046)/year of increased age (P < 0.001) and 3.71 (95% CI, 2.72-5.05) for patients with regional or distant spread. Conclusions: Knowledge of patient and tumor characteristics that influences survival is paramount in dictating management. The present study illustrates that age and stage are factors significantly associated with CSS in PUC.

The foundation of the family and consumer sciences (FCS) can be traced back to the legendary Ellen Swallows Richards. Richards was the first female to graduate with a chemistry degree from Vassar College and the first female accepted into the Massachusetts Institute of Technology (MIT), where she would eventually become MIT's first female professor (Ford, 2008). Richards would later found the American Home Economics Association, now the American Association of Family & Consumer Sciences. Throughout her lifetime, she would lay the groundwork for the discipline known as home economics (now family and consumer sciences), and continue to advocate for the application of scientific and management principles in real-world settings both in the home and in the workplace. Many of these original scientific principles have reentered the national educational conversation through the current emphasis on Science, Technology, Engineering, and Mathematics (STEM) education and the need for a STEM-literate population.

INTRODUCTIONHuman papillomavirus (HPV) is a common sexually transmitted infection in the United States that can lead to both malignant (high-risk) and benign (low-risk) findings. These low-risk findings include both genital condyloma, anal warts, and adult or juvenile papillomatosis, which are directly attributable to subtypes HPV 6 and HPV 11. We aim to estimate the prevalence of genital wart infections in men in the US population using a nationwide sample. METHODSThe NHANES database was queried for all men aged 18 to 59 years during the years 2013 to 2014. During these years, the survey included penile swabs that were tested for HPV infection from 37 subtypes using PCR. Information was also obtained regarding patient reported history of having a genital wart infection previously. RESULTSA total of 1757 men had information regarding HPV DNA. Fifty-three men tested positive for HPV 6 or HPV 11 DNA. This corresponds to an estimated prevalence of 2.9% (95% confidence interval, 2.2–3.8) of men aged 18–59 years. In addition, 2.2% (95% confidence interval, 1.5–3.3) of men reported a history of genital wart infection. There was no significant association with genital HPV DNA detection with age. Increasing number of sexual partners was associated with higher rates of both genital warts and HPV 6 and HPV 11 DNA. CONCLUSIONSThe estimated prevalence of genital HPV DNA in the US male population is 2.9%. This burden of disease could potentially be lowered with increased usage of quadrivalent and nonavalent vaccinations.
