    Abstract Background and problem: A health care transition focused quality improvement project was implemented in a large urban pediatric endocrinology clinic to evaluate the effectiveness of the administration of the Transition Readiness Assessment Questionnaire (TRAQ) by identifying barriers to implementation and creating a more sustainable format.
    Methods and intervention: A pre- and post-intervention evaluation design was used in this quality improvement project. A twelve-month chart review of pediatric endocrine clinic patients diagnosed with diabetes who were 14 years of age or older and met eligibility criteria was conducted. Patients given the TRAQ tool were identified and assessed for documentation of goals and goal achievement. Discussions regarding the implementation of the TRAQ tool were conducted with clinic staff to identify process barriers and develop solutions. A post-implementation twelve-month review was conducted to evaluate for improved documentation and achievement of transition focused goals.
    Results: Several barriers were identified that minimized the effectiveness of the TRAQ tool including lack of staff trained to assist with insulin pump and meter downloads and proximity of diabetes software. Additional staff were trained, and software was relocated to a more centrally located area with greater staff accessibility to allow for discussion of transition goals with patient and family. The new process resulted in a 100% increase in documentation of transition goals and met goals (p ≤0.001).
    Conclusions: The TRAQ tool is valuable for directing transition needs if implementation barriers such as staff training and accessibility to software are monitored and addressed. Frequent evaluation of the administration of the TRAQ tool protocol in the clinic setting is recommended in order to support pediatric patients' successful transition to adult care.

    Abstract This quasi-experimental study examined a guided learning approach towards the use of mobile devices and investigated the performance of language learners who were guided in the usage. A total of 419 students from two faculties were invited to participate in this 8-week intervention, 155 participants in the control group and 264 in the experimental group. In the experimental group, the researchers incorporated guided activities Module Intervention Model (MIM) using mobile devices into the ESL lessons whereas the control group lessons were without guided activities. Participants from both groups were asked to record their daily mobile device use for activities related to English language learning using an online form. These data were compared to the results of the tests conducted pre- and post-treatment. At the end of the study, students who received guided language activities utilizing the mobile devices had significantly higher levels of language performance than control group students. However, treatment group students who spent more time using mobile devices to learn the language did not display better performance compared to those who spent minimal time. This finding re-established the importance of guided activities as intervention to facilitate students' learning and points to the need for curricular modernization and faculty development in the instructional use of technology. Due to the increased need for online instruction precipitated by "social distancing and isolation' required to overcome the coronavirus pandemic, the need for faculty to acquire skills in guided use of mobile devices for school-related learning is anticipated to be greater than ever.

    Abstract Chemsex is the colloquial term used for a specific pattern of drug use that is increasingly common among men who have sex with men (MSM) globally. The recreational substances employed are used specifically in a sexualized context. The reasons for chemsex among MSM are complex. The Anova Health Institute (Anova) provided harm-reduction services in Cape Town, South Africa in 2013 and 2014. This project, known as Tikking the Boxes had two objectives: first to provide direct harm-reduction services to drug-using MSM in Cape Town, South Africa, and second, to reduce HIV and hepatitis B and C transmission among this population. This was done by identifying drug-using behaviour among MSM and linking them to harm-reduction services. Employing people who were currently using drugs was a novel aspect of this program, and successfully facilitated access to MSM drug-using networks. At the launch of the project, the concept of harm reduction was easily misunderstood by MSM. Another challenge was that the harm-reduction service, encompassing needle exchange, excluded opioid substitution therapy. People who use drugs were employed as outreach workers, requiring the project to be very flexible and adaptable to sometimes complex lives and difficult-to-reach peers. JAB SMART is Anova's new harm-reduction initiative and started in May 2017, with support from the City of Johannesburg Health Department, and is the first project of its kind in the city to provide harm-reduction services to people who inject drugs (PWID) and their sexual partners.

    Abstract Widely researched as separate entities, our understanding of the comorbid effects of childhood obesity and asthma on quality of life is limited. This article discusses the effects of childhood obesity and asthma on self-reported quality of life in low-income African American teens with asthma. When controlling for the influence of symptom frequency, asthma classification, asthma self-efficacy, and asthma self-care levels, body mass index remains a most important factor in determining self-reported quality of life among teens with asthma. Although overweight and obesity did not change the effectiveness of the asthma intervention program, obesity did affect participants quality of life scores.

    Abstract The protective effects of whole grain cereals against heart disease and certain cancers may be due, at least partly, to the antioxidant effects of phenolics concentrated in the bran. However, it is unclear to what extent these phenolics are absorbed, and whether these phenolics exert significant physiological antioxidant effects. Thus, this study aimed to compare total phenolics (TP) and antioxidant potential (AOP) in the plasma and urine of humans following consumption of a single meal of unprocessed wheat bran or a refined cereal (ground white rice). Using a randomized cross-over design, 17 adults consumed approximately 93 g of wheat bran or ground rice after an overnight fast. Baseline and postmeal plasma and urine samples were analyzed for TP (Folin-Ciocalteu method) and AOP (FRAP method). Compared with ground rice, wheat bran gave significantly (P < 0.05) higher plasma TP at 1 hr, and significantly (P < 0.001) higher plasma AOP from 0.5 to 3 hr. Furthermore, compared with ground rice, wheat bran led to consistently higher TP and AOP in urine, and these differences were significant (P < 0.05) at 2 hr. Comparisons with data from a range of other phenolic-rich foods indicated that wheat bran phenolics are relatively well absorbed and may enhance antioxidant status.

    Abstract During July 2021, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.617.2 variant infections, including vaccine breakthrough infections, occurred after large public gatherings in Provincetown, Massachusetts, USA, prompting a multistate investigation. Public health departments identified primary and secondary cases by using coronavirus disease surveillance data, case investigations, and contact tracing. A primary case was defined as SARS-CoV-2 detected <14 days after travel to or residence in Provincetown during July 3-17. A secondary case was defined as SARS-CoV-2 detected <14 days after close contact with a person who had a primary case but without travel to or residence in Provincetown during July 3-August 10. We identified 1,098 primary cases and 30 secondary cases associated with 26 primary cases among fully and non-fully vaccinated persons. Large gatherings can have widespread effects on SARS-CoV-2 transmission, and fully vaccinated persons should take precautions, such as masking, to prevent SARS-CoV-2 transmission, particularly during substantial or high transmission.

    Abstract Children, ages 5-6 and 9-10 years, and adults spent 6 min with a man (toucher) who administered a test that required interpersonal touch. The test was briefly interrupted by a woman (intruder). Afterward, the participant-witnesses provided a memory report that included free recall, answers to objective-memory questions, and two lineup identifications. Relative to the adults and older children, the 5- to 6-year-olds gave less complete free recall and made more errors in answering objective questions about the features and actions of the toucher and the intruder. On recognition tests, both the 5- to 6- and 9- to 10-year-olds were somewhat less likely than adults to make accurate lineup decisions about the toucher and much less likely to accurately identify the briefly seen intruder. Children may remember even salient stimuli and actions more poorly than adults do, but there was no evidence that children misremembered touches that did not occur.

    Abstract We present measurements of the cross section and double-helicity asymmetry A_{LL} of direct-photon production in p[over →]+p[over →] collisions at sqrt[s]=510  GeV. The measurements have been performed at midrapidity (|η|<0.25) with the PHENIX detector at the Relativistic Heavy Ion Collider. At relativistic energies, direct photons are dominantly produced from the initial quark-gluon hard scattering and do not interact via the strong force at leading order. Therefore, at sqrt[s]=510  GeV, where leading-order-effects dominate, these measurements provide clean and direct access to the gluon helicity in the polarized proton in the gluon-momentum-fraction range 0.02<x<0.08, with direct sensitivity to the sign of the gluon contribution.<br />
