T cell based immunotherapies can be applicable to acute myeloid leukemia (AML). Therefore, the selection of optimal T cells, cell manufacturing, and therapeutic T cell engineering are essential for the development of effective adoptive T cell therapies for AML. Autologous tumor-infiltrating lymphocytes (TILs) have been in clinical trials to treat solid malignancies. Herein, we assessed whether TILs can be isolated from the bone marrow (BM) of AML patients, expanded ex vivo and utilized as a novel therapeutic strategy for AML. To this end, firstly we analyzed the immunophenotypes of a series of primary BM samples from AML patients (N = 10) by flow cytometry. We observed a variable amount of CD3+ TILs (range ∼2.3–∼32.6% of mononuclear cells) among BM samples. We then developed a novel protocol that produced a three-log ex vivo expansion of TILs isolated from AML patient BM (N = 10) and peripheral blood (PB) (N = 10), including from patients with a low number of CD3+ T cells, within 3, 4 weeks. Further, we identified previously described naïve T cells (CCR7+CD95-/or CD62L+CD45RA+) in AML BM and PB samples, which seemed to be required for a successful TILs ex vivo expansion. Finally, we showed that the expanded TILs could: (1) cause cytotoxicity to autologous AML blasts ex vivo (90.6% in control without T cell treatment vs. 1.89% in experimental groups with PB derived T cells and 1.77% in experimental groups with BM derived TILs, p

Background: Regular physical activity is crucial for healthy aging, but older adults are the least active age group. This study explored the feasibility, acceptability, and efficacy of a multilevel mHealth intervention for increasing physical activity of older adults living in a retirement community. Methods: Participants included 54 older adults (mean age = 81.2 y, 77.8% female, 98.1% white) living in a retirement community. Participants received a Fitbit Zip and access to a multilevel mHealth physical activity intervention (MapTrek Residential) for 8 weeks. Physical activity (in steps per day) and intervention compliance (days worn) were measured objectively with the Fitbit for 12 weeks (8-wk intervention plus 4-wk follow-up). Psychosocial outcomes (social support, self-efficacy, and outcome expectations) were assessed at baseline and 8 weeks. Acceptability outcomes were assessed with an open-ended process evaluation survey and focus groups. Descriptive statistics and linear mixed models were used to examine intervention effects. Results: Participants increased daily steps from 5438 steps per day at baseline (95% CI, 4620 to 6256) to 6201 steps per day (95% CI, 5359 to 7042) at week 8 (P P = .92). Conclusions: Our multilevel mHealth physical activity intervention was effective for increasing physical activity older adults over 8 weeks. Additional research focused on maintaining physical activity gains with this approach is warranted.

Background Bacille Calmette-Guérin (BCG) vaccination has beneficial off-target effects that may include protecting against non-mycobacterial infectious diseases. We aimed to determine whether neonatal BCG vaccination reduces lower respiratory tract infections (LRTI) in infants in the Melbourne Infant Study: BCG for Allergy and Infection Reduction (MIS BAIR) trial. Methods In this investigator-blinded trial, neonates in Australia were randomized to receive BCG-Denmark vaccination or no BCG at birth. Episodes of LRTI were determined by symptoms reported in parent-completed, 3-month questionnaires over the first year of life. Data were analyzed by intention-to-treat using binary regression. Results A total of 1272 neonates were randomized to the BCG vaccination (n = 637) or control (n = 635) group. The proportion of participants with an episode of LRTI in the first year of life among BCG-vaccinated infants was 54.8% compared to 58.0% in the control group, resulting in a risk difference of −3.2 (95% confidence interval, −9.0 to 2.6) after multiple imputation. There was no interaction observed between the primary outcome and sex, maternal BCG, or the other prespecified effect modifiers. Conclusions Based on the findings of this trial, there is insufficient evidence to support the use of neonatal BCG vaccination to prevent LRTI in the first year of life in high-income settings.

Torsional deformities of the lower limbs in children and adolescents are a common cause of in-toeing gait and cause gait deviations. The purpose of this study was to examine the relationship of children and adolescents with suspected Idiopathic Torsional Deformities (ITD) and pain, gait function, activity and participation.A retrospective review of all children and adolescents who attended our Centre over a 5-year period for evaluation of the effect of ITD. All children completed three-dimensional gait analysis (3DGA), standardized physical examination, medical imaging and the Pediatric Outcomes Data Collection Instrument (PODCI). Statistical analysis was completed using two sample t-tests, Pearson's Correlation and linear regression.Fifty children and adolescents, 40 females and 10 males with a mean age of 13.5 years were included. Children reported a high prevalence of pain(86%), had increased internal hip rotation(p = 0.002) and decreased external hip rotation(p0.001) on physical examination when compared to published normative data. Medical imaging showed a mean(SD) femoral neck anteversion (FNA) of 38°(13°) and external tibial torsion of 39°(12°). Mean(SD) PODCI score was 32(16), indicating these children are functioning below their typically developing peers. The 3DGA kinematics show deviations from typical data including hip rotation, foot progression, pelvic tilt, hip flexion and knee extension. Observed mild kinetic deviations were within typical limits. The relationship between FNA and gait parameters, FNA and PODCI and gait and PODCI were weak.These children and adolescents have altered gait and experience pain leading to impaired function and diminished participation. Therefore, ITD is not purely a cosmetic issue.

OBJECTIVE The aim of this study was to compare learner satisfaction and experience with a table-mounted, projecting, high-definition telescopic camera system (VITOM) versus traditional learner observation during vaginal surgery. METHODS Medical student and resident learners were randomized to vaginal surgery observation with or without the use of VITOM. We collected data on learner characteristics and their experience with vaginal surgery. After the surgery, learners completed the faculty/preceptor and working environment domains of the Veterans Affairs Learner's Perceptions Survey (VA LPS). The primary outcome was learners who were "very satisfied" on the VA LPS faculty/preceptor domain. We queried their ability to observe the surgery and satisfaction with learning in the operating room using a 100-mm visual analog scale. RESULTS Ninety-two learners completed the study (n = 44 VITOM, n = 48 no VITOM). There was no significant difference between groups in the proportion of learners "very satisfied" on the VA LPS faculty/preceptor domain (93.2% VITOM vs 91.5% no VITOM; odds ratio, 1.27; 95% confidence interval, 0.20-9.19; P = 0.99). Learners in the VITOM group were more likely to report ability to see what the main surgeon was doing (93.2% VITOM vs 62.5% no VITOM; odds ratio, 8.02; 95% confidence interval, 2.07-46.32; P < 0.01). Using the visual analog scale, learners in the VITOM group reported higher satisfaction with learning in the operating room (median, 96 [interquartile range, 89-100] VITOM vs median, 80 [interquartile range, 57-98] no VITOM; P < 0.01). CONCLUSION The use of a table-mounted, projecting, telescopic camera system during vaginal surgery showed no difference in learner satisfaction on validated questionnaires but resulted in improved experience and visualization.

Purpose This article demonstrates the use of a new SPECT/CT acquisition protocol in patients with differentiated thyroid cancer (DTC). Methods SPECT/CT scans (FASpecT/CT) with fewer angle acquisitions were retrospectively reviewed in 30 DTC patients treated with radioiodine at University Hospital, San Antonio, Tex, from July 2017 to March 2019. This FASpecT/CT of 12 versus 60 to 64 sampled views for convention SPECT was made possible by iterative reconstruction. Results The FASpecT/CT protocol was judged to increase lesion detection in patients with low count rates. Furthermore, in patients with higher count rates, this technique reduced the acquisition time. FASpecT/CT patient images are shown as case examples in 4 of the 30 patients reviewed. Conclusions This FASpecT/CT acquisition in radioiodine-treated DTC offers the potential of higher sensitivity for metastatic lymph node detection in low count rates and a significant decrease in imaging time in high count rates. These advantages make SPECT/CT imaging more acceptable for patients who have difficulty with longer imaging times, to include the pediatric population.

Dysregulation of the autonomic nervous system (ANS), which can be indexed by heart rate variability (HRV), has been posited to contribute to core features of autism spectrum disorder (ASD). However, the relationship between ASD and HRV remains uncertain. We assessed tonic and phasic HRV of 21 children with ASD and 21 age- and IQ-matched typically developing (TD) children and examined (1) group differences in HRV and (2) associations between HRV and ASD symptomatology. Children with ASD showed significantly lower tonic HRV, but similar phasic HRV compared to TD children. Additionally, reduced tonic HRV was associated with atypical attentional responsivity in ASD. Our findings suggest ANS dysregulation is present in ASD and may contribute to atypical attentional responses to sensory stimulation.

Bile cast nephropathy (BCN) is an underdiagnosed cause of acute kidney injury (AKI). The precise pathogenesis of bilirubin tubular toxicity remains unknown. The aim of this study is to explore the cellular and molecular pathophysiology of human BCN. Paraffin-embedded sections of renal biopsy tissue from a BCN patient were stained by immunohistochemistry (IHC) for oxidative stress (4-hydroxynonenal), immune cell subpopulations, including dendritic cells (CD1c), macrophages (CD68) and T cells (CD3), and inflammasome activation by staining for active-caspase-1 and the inflammasome adaptor protein, ASC (apoptosis-associated speck-like protein containing a caspase activation and recruitment domain). Quantitative analyses of IHC staining were compared to healthy renal cortical tissue. We identified yellow to brown granular casts within the BCN case, consistent with the presence of bile pigment. The presence of bile pigment was associated with strong tubular 4-hydroxynonenal staining intensity, a marker of oxidative stress. Diffuse tubulointerstitial inflammatory cell infiltrate was detected, with elevated CD1c, CD68 and CD3 staining. Foci of inflammasome activity were co-localized with this intense immune cell infiltration, with increased active-caspase-1 and ASC staining. Our findings are the first to suggest that bile casts may lead to oxidative stress and trigger the inflammasome signalling cascade, leading to interstitial inflammation and driving AKI pathobiology. SUMMARY AT A GLANCE The report suggests that bile casts may lead to oxidative stress and trigger the inflammasome signalling cascade, leading to interstitial inflammation and driving bile cast nephropathy pathobiology.

Thyroid nodules (TN) are detected in a small number of asymptomatic children and adolescents but are more frequently malignant (22–26%) than in adults leading some clinicians to perform thyroid ultrasound (US) for all children with goiter or autoimmune thyroiditis (AIT). Our study was designed to determine if suspicious clinical features predict the presence of TN in children with goiter or AIT so that US could be performed on those at highest risk. This was a retrospective review of 223 children and adolescents with goiter or AIT evaluated at a single institution. US was not performed on all patients. It is our practice to define glands that are large, firm, or nodular to palpation as “suspicious”. Suspicious glands were interrogated by US and if TN was confirmed, this was further evaluated by fine-needle aspiration followed by surgery if indicated. The median age was 12.9 years with 74.4% female. TN were confirmed by US in 16.6% of all patients but only 4.8% of those with AIT. By univariate analysis, TN were more common in those with family history of TN or differentiated thyroid carcinoma (DTC), thyroid asymmetry, and lower thyrotropin (TSH) levels. Differentiated thyroid carcinoma (DTC) was identified in 10.8% of TN and 1.8% of all patients. Firmness was significantly more common in patients with DTC (p = 0.0013). TN were less common in those with AIT than reported in previous studies, suggesting that clinical features might fail to identify the majority of TN in patients with AIT. However, patients with asymmetric thyroid and a family history of TN or DTC have greatest risk for TN.

OBJECTIVES 1) Identify factors that influence African American physicians to choose a career in otolaryngology; 2) determine the predominant practice setting for African American otolaryngologists who can be role models; and 3) determine if the presence of an African American otolaryngologist in academic setting influences career choice. METHODS Survey methodology included a 15-item survey to determine trends in practice and factors that influenced choice of specialty. RESULTS The results were reviewed for trends influencing career choice and practice location and stratified by age group. Most African American otolaryngologists are in academic practice and have subspecialty fellowship training. Enjoying medical student clerkship was the most frequently cited reason why African Americans chose otolaryngology as a career regardless of age. Early exposure was a driving factor in those 30 to 40 years old. Receiving mentorship was less influential in career choice for all age groups, but there was a positive association between those who were mentored in training and those who mentor faculty. CONCLUSION The findings suggest the continued need for initiatives to increase African Americans in our specialty. Encouraging early exposure, intentional mentoring of students, and development of African American role models who can be mentors may help increase the number of African American otolaryngologist faculty. This can help our specialty achieve racial parity in a percentage that matches the number of African Americans in the United States workforce. LEVEL OF EVIDENCE 5 Laryngoscope, 130:2336-2342, 2020.

Objective The purpose of this study was to explore the hypothesis that the relationship between hearing problems and cardiovascular disease (CVD) includes a connection to psychological distress. Design We used generalized structural equation modeling to assess relationships between self-reported measures of hearing problems, psychological distress, and CVD in a pooled sample of 623,416 adult respondents in the 1997–2017 National Health Interview Survey. Hearing status without hearing aids was self-reported on an ordinal scale and further grouped for this study into 3 categories (excellent or good hearing, little or moderate trouble hearing, and a lot of trouble or deaf). Six CVDs (stroke, angina pectoris, hypertension, heart attack, coronary heart disease, or other heart condition/disease) were incorporated as a latent variable. Psychological distress was evaluated by the Kessler 6 Scale ( Kessler et al., 2010 ). All estimates were population weighted, and standard errors were adjusted for a complex survey design. Results Nearly 83% reported excellent or good hearing, 14% reported a little or moderate trouble hearing, and 3% reported a lot of trouble hearing or said they were deaf. Hearing problems were positively associated with CVD. Relative to those reporting excellent/good hearing, adults reporting trouble hearing had a higher probability of CVD. Hearing problems were also significantly associated with psychological distress. When psychological distress was applied to the model, positive associations between hearing problems and CVD were attenuated but still significant. Results are consistent with the hypothesis that the connection between self-reported hearing problems and CVD is mediated through psychological distress. Conclusions The relationship between self-reported hearing problems and CVD is mediated by psychological distress. Further research is needed to identify causal pathways and psychophysiological mechanisms involved in this relationship and to identify effective methods for addressing cardiovascular health-related psychosocial factors in the treatment of hearing impairment.

Background:Nutritious underutilized foods (NUFs) significantly contribute to sustainable dietary diversity but are often unused for many reasons.Objective:We assessed the influence of food security status (FSS) and anemia-related knowledge (ARK) on perceptions about Solanum torvum (turkey berry) and Rhynchophorus phoenicis Fabricius (palm weevil larvae) among Ghanaian caregivers.Methods:A cross-sectional survey was conducted among 891 caregivers (aged 20-49 years), who have children 6 to 59 months old, from Upper Manya Krobo district (Eastern region), Kumasi metropolitan (Ashanti region), Ho municipality (Volta region), La-Nkwantanang-Madina, and Ga West municipality (Greater-Accra region), Ghana. Food security status, ARK, and perceptions about the 2 NUFs were obtained using pretested semi-structured questionnaire. Logistic regression models were used to determine effect of FSS and ARK on perception outcomes.Results:Thirty-six percent of caregivers were food secure, while 13.9%, 28.4%, and 21.7%, respectively, were mildly, moderately, and severely food insecure. Most caregivers (62.0%) scored above 70% on ARK. High favorable perception was significantly lower for palm weevil larvae than that for turkey berry. Food secure caregivers were 4.5 times more likely to have poor favorable perceptions about palm weevil larvae than food insecure caregivers ( P = .03). However, food secure caregivers were 2.9 times more likely to have high favorable perceptions about turkey berry than food insecure caregivers ( P < .001). Caregivers’ knowledge about anemia was associated with high favorable perception about turkey berry by 3.3-fold (95% confidence interval: 2-5.5, P = .001).Conclusions:Nutrition education about turkey berry and palm weevil larvae is needed to encourage their use for promoting nutrient density of complementary and household foods.

Introduction Heparin‐induced thrombocytopenia (HIT) is a potentially life‐threatening adverse reaction of heparin. Laboratory evaluation of HIT is often not available within a reasonable time. We evaluated the HemosIL® HIT‐Ab(PF4‐H) (Instrumentation Laboratory), a rapid, on‐demand, fully automated, latex immunoturbidimetric assay (LIA). Materials and methods Following determination of the LIA's reference interval and cutoff values, a multicenter study was conducted between March 2013 and June 2015. Plasma samples of HIT‐suspected patients (n = 632) were collected and evaluated by LIA on the ACL TOP® Family systems (Instrumentation Laboratory), enzyme‐linked immunosorbent assays (EIA), and serotonin release assay (SRA). Patient characteristics, medical conditions, comorbidities, laboratory results, and medications were collected via medical chart review. The pretest clinical probability of HIT was also calculated for each patient. Results Based on the 95% reference interval for healthy donors and HIT‐negative patients, a LIA value ≥1.0 U/mL was interpreted positive. The overall agreement of LIA versus EIA and SRA results were 90% (95% CI 88%‐92%) and 79% (95% CI 75%‐82%), respectively. The negative predictive value for LIA and EIA was comparable (87%) with SRA. The positive and negative percent agreements with the clinical probability were 89% (95% CI 69%‐97%) and 86% (95% CI 83%‐89%), respectively, with a negative predictive value of 99.6% (95% CI 98%‐100%). Discussion Overall, the LIA results were comparable to those of EIA and SRA. This fully automated assay with a remarkable short analytical turnaround time of

Objective As part of a statewide Supplemental Nutrition Assistance Program–Education program evaluation, Fresh Conversations (FC) facilitators (ie, educators) provided input into a new delivery model. Methods The researchers interviewed 25 FC facilitators. Interviews were recorded, transcribed verbatim, and analyzed for common themes. Results Most facilitators were women with at least 1 year of FC experience. Key motivators for serving as an FC facilitator included alignment with current employment responsibilities and gerontology interest. Training was viewed as helpful, thorough, and self-explanatory. Implementation challenges included recruitment, public speaking, and time management. Nearly all stated that FC content was important and that other seniors at other congregate meal sites would be interested in FC. Conclusions and Implications Findings suggest that facilitators were pleased with FC; however, their experiences might be further improved through enhanced training. Further exploration into community food and nutrition program educators’ feedback is needed to ensure these programs meet their needs as well as those of the audience.

Summary Background Rapid demographic, epidemiological, and nutritional transitons have brought a pressing need to track progress in adolescent health. Here, we present country-level estimates of 12 headline indicators from the Lancet Commission on adolescent health and wellbeing, from 1990 to 2016. Methods Indicators included those of health outcomes (disability-adjusted life-years [DALYs] due to communicable, maternal, and nutritional diseases; injuries; and non-communicable diseases); health risks (tobacco smoking, binge drinking, overweight, and anaemia); and social determinants of health (adolescent fertility; completion of secondary education; not in education, employment, or training [NEET]; child marriage; and demand for contraception satisfied with modern methods). We drew data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016, International Labour Organisation, household surveys, and the Barro-Lee education dataset. Findings From 1990 to 2016, remarkable shifts in adolescent health occurred. A decrease in disease burden in many countries has been offset by population growth in countries with the poorest adolescent health profiles. Compared with 1990, an additional 250 million adolescents were living in multi-burden countries in 2016, where they face a heavy and complex burden of disease. The rapidity of nutritional transition is evident from the 324·1 million (18%) of 1·8 billion adolescents globally who were overweight or obese in 2016, an increase of 176·9 million compared with 1990, and the 430·7 million (24%) who had anaemia in 2016, an increase of 74·2 million compared with 1990. Child marriage remains common, with an estimated 66 million women aged 20–24 years married before age 18 years. Although gender-parity in secondary school completion exists globally, prevalence of NEET remains high for young women in multi-burden countries, suggesting few opportunities to enter the workforce in these settings. Interpretation Although disease burden has fallen in many settings, demographic shifts have heightened global inequalities. Global disease burden has changed little since 1990 and the prevalence of many adolescent health risks have increased. Health, education, and legal systems have not kept pace with shifting adolescent needs and demographic changes. Gender inequity remains a powerful driver of poor adolescent health in many countries.

The purpose of the study was to develop and test culturally appropriate health promotion materials that were seen to be socially inclusive in regard to blood donation within the Australian-African community. Materials were produced in multiple languages (English, Arabic, Swahili and Kirundi) and were initially developed based on previous pilot data, with feedback from the project partner (Australian Red Cross Blood Service) and the African community. Seven formative focus groups with 62 participants were then conducted to ensure the materials would be effective, credible and culturally acceptable to the target audience, including preferred messages, taglines and images. The response confirmed that quotes and images from community members (as opposed to actors) were critical to ensure messages were engaging and believable, and had meaningful taglines that were perceived to be authentic. The refined materials were then used in a community intervention study. The evaluation included an assessment of respondents’ views of the messages post-intervention. Of the 281 African migrants who saw the campaign materials during the intervention period, the majority (75.8%) strongly agreed that the materials made them feel part of the wider Australian community. These results suggest that engagement in developmental activities with targeted communities is important for creating positively viewed culturally targeted public health campaigns. A six-step process is suggested that could be used by other organizations to ensure that messages are acceptable to targeted migrant communities.

Background Racism and racial discrimination are fundamental causes and determinants of health and health inequalities globally, with children and adolescents particularly vulnerable. Racial discrimination is a common stressor in the lives of many children and adolescents, with growing evidence of negative associations between racial discrimination and multiple domains of child and adolescent health. Addressing racism and racial discrimination must be core public health priorities, even more so among children and young people. Schools are key settings in the lives of children and adolescents and become increasingly more important to identity formation. School communities, teachers and peers greatly influence children and adolescents’ beliefs about race and difference. Schools are therefore key sites for the delivery of population-based programs to reduce racism and promote proactive bystander behaviour and healthy resistance to racism among all children and adolescents as well as among the adults. Methods This study examines the feasibility and acceptability of the ‘Speak Out Against Racism (SOAR)’ program, a whole of school, multi-level, multi-strategy program that aimed to promote effective bystander responses to racism and racial discrimination in primary schools. A mixed-methods, quasi-experimental design was used. Students in Years 5 and 6 (10–12 years) across six schools completed surveys pre- and post- intervention (N = 645; 52% female; 6% Indigenous, 10% Middle Eastern, African, Latinx or Pacific Islander, 21% Asian, 52% Anglo/European). Focus groups with students and interviews with staff collected qualitative data about their experiences of the program and their views about the program’s perceived need, implementation, impacts and suggested improvements. Results Quantitative data showed student prosocial skills and teacher inter-racial climate improved in intervention schools compared to comparison schools. Qualitative data highlighted teacher attitudinal and behaviour change regarding racism, and student reduced interpersonal racial discrimination, improved peer prosocial norms, commitment to anti-racism, knowledge of proactive bystander responses and confidence and self-efficacy to intervene to address racism. Conclusions This study provides quantitative evidence of the potential of the SOAR program to improve the prosocial skills of students and their perceptions of the inter-racial school climate provided by their teachers. This program also provided qualitative evidence of the potential to promote teacher and student attitudinal and behavioural change. Further refinement and testing of the program in a large scale implementation trial is recommended.

Monoclonal antibodies (mAbs) with neutralizing activity against SARS-CoV-2 have demonstrated clinical benefit in cases of mild to moderate SARS-CoV-2 infection, substantially reducing the risk for hospitalization and severe disease1-4. Treatment generally requires the administration of high doses of these mAbs with limited efficacy in preventing disease complications or mortality among hospitalized COVID-19 patients5. Here we report the development and evaluation of Fc-optimized anti-SARS-CoV-2 mAbs with superior potency to prevent or treat COVID-19 disease. In several animal models of COVID-19 disease6,7, we demonstrate that selective engagement of activating FcγRs results in improved efficacy in both preventing and treating disease-induced weight loss and mortality, significantly reducing the dose required to confer full protection upon SARS-CoV-2 challenge and treatment of pre-infected animals. Our results highlight the importance of FcγR pathways in driving antibody-mediated antiviral immunity, while excluding any pathogenic or disease-enhancing effects of FcγR engagement of anti-SARS-CoV-2 antibodies upon infection. These findings have important implications for the development of Fc-engineered mAbs with optimal Fc effector function and improved clinical efficacy against COVID-19 disease.

Background Healthcare workers are usually the first responders during outbreaks and are instrumental in educating the populace about the prevention of different diseases and illnesses. The aim of this study was to assess the association between healthcare workers’ characteristics and knowledge, attitudes and practices toward Zika virus. Methods This was a cross-sectional study that collected data from healthcare workers at 3 medical facilities using a validated self-administered questionnaire between July 2017 – September 2017. Logistic regression models were used to examine the association between sociodemographic and knowledge, attitudes, and practices. Results A total of 190 healthcare workers were analyzed. Of these, 60, 72.6 and 64.7% had good knowledge, positive attitudes, and good practices toward Zika virus, respectively. Healthcare workers without a formal degree were less likely to have good knowledge of Zika virus (adjusted odds ratio (AOR) = 0:49; 95% confidence interval (CI) = 0.24–0.99) compared to those with a formal degree. Reduced odds for positive attitude towards Zika virus were observed in healthcare workers with low income as compared to those with high income (AOR = 0.31; 95% CI =0.13–0.75). Being younger than 40 years old was associated with poor Zika virus practices (AOR = 0:34; 95% CI = 0.15–0.79). Conclusions Significant association between healthcare workers’ sociodemographic characteristics and Zika virus knowledge, attitudes and practices were observed. Public health interventions that seek to increase Zika virus awareness should aim to train healthcare workers who are younger, without formal degree and those earning low income.

Background There is a current lack of consensus amongst paediatric radiologists and respiratory paediatricians as to the correct CT definition of bronchiectasis in children. Using contemporary low-dose CT, our objectives were to determine the upper limit of normal for broncho-arterial ratio (BAR) in children and to evaluate the effect of age and general anaesthesia. Methods Measurements of 330 broncho-arterial ratios from 51 children (0–19 years) undergoing low-dose CT chest for non-respiratory indications were performed by 3 blinded observers (two radiologists, one respiratory physician) using four different methods. Inter-observer reliability, mean BAR and reference ranges (mean±2SD) were calculated. Correlation between age and BARs were examined. Mean BAR for CT under general anaesthesia and CT awake were compared. Results Inter-observer correlation was extremely high for all measurements (0.93–0.97). There was a weak positive correlation between age and BAR in the CT-awake group (r = 0.33, 95%CI: 0.03–0.57; p = 0.031) using the inner-bronchial wall to artery, short-axis measurement. CT under general anaesthesia showed significantly higher BAR compared to CT-awake [mean difference 0.13 (95%CI: 0.05–0.22; p = 0.004)]. For the CT-awake group, the mean BAR was 0.65 (range: 0.42 to 0.89), with no child having a BAR above 0.9. Conclusion Using a standardised approach, we have shown that a broncho-arterial ratio above 0.9 in children undergoing awake CT is abnormal and suggests airway widening or radiological bronchiectasis. Children undergoing CT under anaesthesia have higher BARs than those undergoing awake CT. A weak positive correlation between broncho-arterial ratio and age was observed, hence, age-adjusted cut-offs for BAR warrant further study.

Objective Preexposure prophylaxis (PrEP) is a safe and effective method for HIV prevention, but little is known about PrEP uptake in rural and small urban areas. We described rates and predictors of HIV PrEP initiation among public health clients in rural and small urban areas in Iowa. Methods This was a prospective cohort study of clients with PrEP indications served by HIV testing and disease intervention specialist/partner services (DIS/PS) programs in public health departments in Iowa from February 1, 2018, through February 28, 2019. Eligible participants were aged 18-70 and referred for PrEP by public health personnel. Participants completed surveys at enrollment addressing demographic characteristics; sexual history; previous drug use; PrEP experiences; and knowledge, attitudes, and beliefs about PrEP. A follow-up survey assessed PrEP initiation at 30 days. We compared baseline characteristics of PrEP initiators and non-initiators. Results Two hundred thirty-four public health clients consented to participate in the study; 189 completed the baseline survey, and 117 (61.9%) completed the follow-up survey. The mean age of participants in the baseline survey was 30 (range, 18-68); 109 (57.7%) were male, 127 (67.2%) were White, and 169 (89.4%) lived in a rural or small urban area. Of 117 participants in the follow-up survey, those who initiated PrEP were significantly more likely than those who did not initiate PrEP to be referred by DIS/PS programs (46.7% vs 7.8%, P < .001) and to recognize that PrEP was ≥90% effective (86.7% vs 35.3%, P = .001). No PrEP initiators and 8 PrEP non-initiators agreed that PrEP is for promiscuous people (0% vs 7.8%, P = .04). Perceived PrEP stigma was low and not associated with PrEP initiation. Conclusions PrEP initiation rates were low among rural and small urban health department clients. Interventions are needed to improve linkage to PrEP among rural and small urban public health clients.

This study examined the impact of the Supplemental Nutrition Assistance Program-Education (SNAP-Ed) program Fresh Conversations (FC) on the nutritional risk (NR) of older adults (OAs). A convenience sample of OAs (207 Treatment, 148 Control) completed questionnaires comprised of validated measures to assess NR, barriers to healthy eating self-efficacy (SE), food safety behaviors (FSB), and food security (FS) at three-time points over 9 months. Participants were mostly white (92.4%), older (age 81+ years, 40.1%), widowed (52.4%), and females (75.2%). Independent t-tests identified baseline differences among groups. Analysis of covariance assessed group changes at each time point for each measure. Block regression determined which variables influence baseline NR. Baseline NR risk was significantly predicted by SE (β = 0.21), education (β = 0.19) and age (β = 0.14) (p

Older adult (OA) dietary practices may be placing them at nutritional risk. This cross-sectional study examined the dietary intake frequencies (DIF) and nutritional risk (NR) using the Dietary Screening Tool (DST) of OA attending community-based nutrition education and physical activity programs. Most were white females aged 60-80 years. The majority (80.1%) were classified as "at NR" or "at possible NR." Participants had "low" lean protein, dairy, and processed meat DIF and "moderate" whole fruit and juice, total and whole grains, vegetables and added fats, sugars, and sweets DIF. State influenced whole fruit and juice (p ≤ .001) and vegetable (p = .021) DIF, age influenced processed meat DIF (p = .001), and gender influenced NR (p = .006), vegetable (p = .022), and processed meat (p = .033) DIF. Results indicate that OA participating in lifestyle interventions are at NR. When developing future nutrition education programs, educators should consider sociodemographic factors to promote dairy and protein-rich foods to OA at NR.

The rate of competitive employment, or employment in community settings for minimum wage or higher, of working-age individuals with disabilities trails behind individuals without disabilities in the United States. These statistics are even more alarming among Hispanic individuals who have disabilities. The purpose of this study was to explore the negative and positive experiences of Hispanic caregivers from a Midwestern state as they support their family members with disabilities to achieve positive postschool outcomes, including competitive employment. We conducted semistructured interviews with 13 caregivers of family members with disabilities aged 14–25 years. Three key themes emerged from our analysis: (a) negative experiences with school educators, (b) negative experiences with community-based service providers, and (c) positive experiences and strategies for overcoming barriers. Implications for practice and future research are discussed.

Purpose The purpose of this study was to investigate the effects of 2nd language proficiency and linguistic uncertainty on performance and listening effort in mixed language contexts. Method Thirteen native speakers of Dutch with varying degrees of fluency in English listened to and repeated sentences produced in both Dutch and English and presented in the presence of single-talker competing speech in both Dutch and English. Target and masker language combinations were presented in both blocked and mixed (unpredictable) conditions. In the blocked condition, in each block of trials the target–masker language combination remained constant, and the listeners were informed of both prior to beginning the block. In the mixed condition, target and masker language varied randomly from trial to trial. All listeners participated in all conditions. Performance was assessed in terms of speech reception thresholds, whereas listening effort was quantified in terms of pupil dilation. Results Performance (speech reception thresholds) and listening effort (pupil dilation) were both affected by 2nd language proficiency (English test score) and target and masker language: Performance was better in blocked as compared to mixed conditions, with Dutch as compared to English targets, and with English as compared to Dutch maskers. English proficiency was correlated with listening performance. Listeners also exhibited greater peak pupil dilation in mixed as compared to blocked conditions for trials with Dutch maskers, whereas pupil dilation during preparation for speaking was higher for English targets as compared to Dutch ones in almost all conditions. Conclusions Both listener's proficiency in a 2nd language and uncertainty about the target language on a given trial play a significant role in how bilingual listeners attend to speech in the presence of competing speech in different languages, but precise effects also depend on which language is serving as target and which as masker.

Although increasing numbers of students with disabilities are attending college, they graduate at lower rates compared to students without disabilities. In order to understand how to effectively prepare students with disabilities and provide meaningful support to college students with disabilities, we investigated the experiences of students registered with the disability service office at a public university located in the eastern region of the U.S. to learn about (a) the degree to which they felt prepared to enter college, (b) the disability-related services they received in college, (c) their perspectives of services received, (d) suggestions for improving services, and (e) their perspectives family involvement in college. We report mixed-methods findings from participants and provide implications for policy and practice.

Objectives: To determine the incidence of early postoperative tympanostomy tube insertion otorrhea and obstruction in pediatric patients receiving antibiotic ear drops with or without steroid perioperatively. Methods: A retrospective chart review was performed on patients who underwent outpatient myringotomy and tube placement. Patients from June 2013 to February 2014 received ciprofloxacin/dexamethasone perioperatively while patients from May 2014 to April 2015 received ofloxacin. Statistical analysis was performed to compare outcomes between the cohorts. Results: One hundred thirty-four patients received topical ciprofloxacin/dexamethasone, and 116 patients received topical ofloxacin. The rate of postoperative otorrhea was 5.2% for the ciprofloxacin/dexamethasone group and 8.2% for the ofloxacin group. Tube obstruction was seen in 6.0% of the ciprofloxacin/dexamethasone group and 5.2% in the ofloxacin group. Neither outcome had a statistically significant difference ( P = .21 and .85, respectively). There was no difference in the rate of effusion at the time of tube placement between the 2 cohorts ( P = .16), and this included subgroup analysis based on effusion type (mucoid, purulent, serous). Patients with a mucoid effusion at the time of surgery were more likely to experience otorrhea/obstruction than patients with dry ears (odds ratio = 2.23, P = .02). Conclusion: No significant difference in the incidence of immediate postoperative tympanostomy tube otorrhea or obstruction was seen between the antibiotic-steroid and antibiotic alone cohorts, regardless of effusion type. Overall, patients with mucoid effusions are more likely to develop tube otorrhea or obstruction at follow-up. Cost-effective drops should be used when prescribing topical therapy to prevent complications after ear tubes.

Acute suppurative thyroiditis is a rare, potentially life-threatening condition. We report the case of a 17-year-old male who initially presented with a thyroid abscess. Due to persistent symptoms and lack of evidence for underlying predisposing factors, he was followed closely and subsequently diagnosed with papillary thyroid cancer. He was successfully managed with surgery. His clinical course, radiological evaluation, and pathology reports are presented here along with a review of the literature. This case of papillary thyroid cancer highlights the need for close follow-up of patients presenting with a thyroid abscess, when other predisposing risk factors are not evident.

The objective of this study was to describe surgeons’ current practices in InterStim® programming after initial implantation and their knowledge of programming parameters. We hypothesized that surgeons performing their own reprogramming would have increased knowledge. We administered a written survey to attendees at the Society of Gynecologic Surgeons Scientific Meeting and analyzed those on which surgeons indicated they offer InterStim® care. The survey queried surgeon characteristics, experience with InterStim® implantation and programming, and clinical opinions regarding reprogramming and tested six knowledge-based questions about programming parameters. Correct response to all six questions was the primary outcome. One hundred and thirty-five of 407 (33%) attendees returned the survey, of which 99 met inclusion criteria. Most respondents (88 of 99; 89%) were between 36 and 60 years, 27 (73%) were women, 76 (77%) practiced in a university setting, and 76 (77%) were trained in Female Pelvic Medicine and Reconstructive Surgery (FPMRS). Surgeons who had InterStim® programming training were more likely to perform their own programming [15/46 (32%) vs 6/47 (13%), p = 0.03]. Most answered all knowledge-based questions correctly (62/90, 69%); no surgeon characteristics were significantly associated with this outcome. Most surgeons cited patient comfort (71/80, 89%) and symptom relief (64/80, 80%) as important factors when reprogramming, but no prevalent themes emerged on how and why surgeons change certain programming parameters. Surgeons who had formal InterStim® programming training are more likely to perform programming themselves. No surgeon characteristic was associated with improved programming knowledge. We found that surgeons prioritize patient comfort and symptoms when deciding to reprogram.

Background & Aims Eosinophilic esophagitis (EoE) is assessed endoscopically (endoscopic activity), based on grades of edema, rings, exudates, furrows, and strictures (EREFS). We examined variations in endoscopic assessments of severity, developed and validated 3 EREFS-based scoring systems, and assessed responsiveness of these systems using data from a randomized placebo-controlled trial of patients with EoE. Methods For the development set, 5 gastroenterologists reviewed EREFS findings from 266 adults with EoE and provided endoscopist global assessment scores (EndoGA, scale of 0 to 10); variation (ΔEndoGA) was assessed using linear regression. We evaluated simple scores (features given arbitrary values from 0 to 3) and developed 2 scoring systems (adjusted score range, 0–100). We then fitted our linear regression model with mean EndoGA to data from 146 adults recruited in centers in Switzerland and the United States between April 2011 and December 2012. For the validation set, we collected data from 120 separate adults (recruited in centers in Switzerland and the United States between May 2013 and July 2014), assessing regression coefficient-based scores using Bland-Altman method. We assessed the responsiveness of our scoring systems using data from a randomized trial of patients with EoE given fluticasone (n=16) or placebo (n=8). Results The distribution of EndoGA values differed among endoscopists (mean ΔEndoGA, 2.6±1.8; range 0–6.6). We developed 2 regression-based scoring systems to assess overall and proximal and distal esophageal findings; variation in endoscopic features accounted for more than 90% of the mean EndoGA variation. In the validation group, differences between mean EndoGA and regression-based scores were small (ranging from –4.70 to 2.03), indicating good agreement. In analyses of data from the randomized trial, the baseline to end of study change in patients given fluticasone was a reduction of 24.3 in simple score (reduction of 4.6 in patients given placebo, P=.052); a reduction of 23.5 in regression-based overall score (reduction of 6.56 in patients given placebo, P=.12), and a reduction of 23.8 (reduction of 8.44 in patients given placebo, P=.11). Conclusion Assessments of endoscopic activity in patients with EoE vary among endoscopists. In an analysis of data from a randomized controlled trial, we found that newly developed scoring systems are no better than simple scoring system in detecting changes in endoscopic activity. These results support the use of a simple scoring system in evaluation of endoscopic activity in patients with EoE. clinicaltrials.gov no: NCT00939263 and NCT 01386112

Despite early differences in orienting to sounds, no study to date has investigated whether children with ASD demonstrate impairments in attentional disengagement in the auditory modality. Twenty-one nine- to fifteen year old children with ASD and 20 age- and IQ-matched TD children were presented with an auditory gap-overlap paradigm. Evidence of impaired disengagement in ASD was mixed. Differences in saccadic reaction time for overlap and gap conditions did not differ between groups. However, children with ASD did show increased no-shift trials in the overlap condition, as well as reduced disengagement efficiency compared to their TD peers. These results provide further support for disengagement impairments in ASD, and suggest that these deficits include disengaging from and shifting to unimodal auditory information.

Summary Background Phenytoin is the current standard of care for second-line treatment of paediatric convulsive status epilepticus after failure of first-line benzodiazepines, but is only effective in 60% of cases and is associated with considerable adverse effects. A newer anticonvulsant, levetiracetam, can be given more quickly, is potentially more efficacious, and has a more tolerable adverse effect profile. We aimed to determine whether phenytoin or levetiracetam is the superior second-line treatment for paediatric convulsive status epilepticus. Methods ConSEPT was an open-label, multicentre, randomised controlled trial conducted in 13 emergency departments in Australia and New Zealand. Children aged between 3 months and 16 years, with convulsive status epilepticus that failed first-line benzodiazepine treatment, were randomly assigned (1:1) using a computer-generated permuted block (block sizes 2 and 4) randomisation sequence, stratified by site and age (≤5 years, >5 years), to receive 20 mg/kg phenytoin (intravenous or intraosseous infusion over 20 min) or 40 mg/kg levetiracetam (intravenous or intraosseous infusion over 5 min). The primary outcome was clinical cessation of seizure activity 5 min after the completion of infusion of the study drug. Analysis was by intention to treat. This trial is registered with the Australian and New Zealand Clinical Trials Registry, number ACTRN12615000129583. Findings Between March 19, 2015, and Nov 29, 2017, 639 children presented to participating emergency departments with convulsive status epilepticus; 127 were missed, and 278 did not meet eligibility criteria. The parents of one child declined to give consent, leaving 233 children (114 assigned to phenytoin and 119 assigned to levetiracetam) in the intention-to-treat population. Clinical cessation of seizure activity 5 min after completion of infusion of study drug occurred in 68 (60%) patients in the phenytoin group and 60 (50%) patients in the levetiracetam group (risk difference −9·2% [95% CI −21·9 to 3·5]; p=0·16). One participant in the phenytoin group died at 27 days because of haemorrhagic encephalitis; this death was not thought to be due to the study drug. There were no other serious adverse events. Interpretation Levetiracetam is not superior to phenytoin for second-line management of paediatric convulsive status epilepticus.

Background/aims Inadequate bowel preparations can necessitate early repeat of colonoscopy and increased healthcare costs. Established risk factors for suboptimal bowel preparation are known, yet data are lacking in the specific subgroup of patients with decompensated cirrhosis. The primary aim of this study was to reduce inadequate bowel preparation rates in patients with decompensated cirrhosis undergoing evaluation for liver transplant via a quality improvement initiative targeting patient education. Methods A total of 121 patients undergoing evaluation at our institution prior to implementation of the quality improvement initiative and 91 patients undergoing evaluation after implementation were included. The initiative was an educational intervention via a 6-minute colonoscopy and split-prep bowel preparation educational video during the initial liver transplantation evaluation visit for all patients with scheduled colonoscopy. Results Inadequate bowel preparation was observed in 36 patients (29.8%) in the pre-intervention period compared to 29 patients (31.9%) in the post-intervention period. This corresponded to a lack of a significant difference in both single-variable analysis and multivariable analysis. Of note, there was a significantly higher rate of inadequate bowel preparation as ascites worsened (P=.028). Conclusion Patient educational video failed to improve bowel preparations in patients undergoing colonoscopy with decompensated cirrhosis.

Despite a growing older adult population, Iowa Congregate Meal Program (CMP) participation has declined. Motivators and barriers to congregate mealsite participation and wellness programming preferences of baby boomers and older adults were examined to provide insight to how to revise and better promote the CMP for the next generation of older adults. Four focus group sessions were conducted with 27 primarily White, rural-residing adults, ages 48-88 years. Participation motivators included educational programs, food, and socialization while barriers included negative perceptions and stereotypes associated with congregate mealsites. Desired wellness programs were viewed as interactive and relevant. Healthcare was the leading wellness need with financial management and physical activity cited as the most-wanted topics of wellness programs. These results provide insight on factors, aside from funding, that may be adversely impacting CMP participation and identifies areas for further investigation.

One in 2900 genotypical men report gender dysphoria, and many undergo gender confirmation surgery to match their physical phenotype to their identity. A variety of surgical techniques are used in male-to-female transgender patients, one of which is bowel vaginoplasty, and postoperative stenosis of the colonic neovagina is common. Extracellular matrix grafts have been used in vaginal reconstruction. with porcine urinary bladder matrix (UBM) acting as a scaffold for smooth-muscle tissue and matrix regeneration. The aim of this surgical video is to describe the use of a UBM biological graft in repair of introital stenosis due to recurrent granulation tissue in the colonic neovagina of a male-to-female transgender patient. A 32-year-old male-to-female transgender patient with a history of rectosigmoid neovagina formation for genital gender confirmation surgery 12 months prior presented with genital granulation tissue and stenosis of her neovaginal introitus. Despite two surgical revisions, the patient developed recurrence of granulation tissue and obliteration of the neovaginal introitus, preventing sexual function of the neovagina. Reconstruction of the neovaginal introitus was performed using UBM. The patient noted improvement in comfort, hygiene, and quality of life following the procedure. This video describes our surgical technique and perioperative clinical findings. We report the novel use of UBM biological graft in the revision of a neovaginal introitus after former rectosigmoid vaginoplasty in a male-to-female transgender patient.

Background Self-report questionnaires are a valuable method of physical activity measurement in public health research; however, accuracy is often lacking. The purpose of this study is to improve the validity of the Global Physical Activity Questionnaire by calibrating it to 7 days of accelerometer measured physical activity and sedentary behavior. Methods Participants (n = 108) wore an ActiGraph GT9X Link on their non-dominant wrist for 7 days. Following the accelerometer wear period, participants completed a telephone Global Physical Activity Questionnaire with a research assistant. Data were split into training and testing samples, and multivariable linear regression models built using functions of the GPAQ self-report data to predict ActiGraph measured physical activity and sedentary behavior. Models were evaluated with the testing sample and an independent validation sample (n = 120) using Mean Squared Prediction Errors. Results The prediction models utilized sedentary behavior, and moderate- and vigorous-intensity physical activity self-reported scores from the questionnaire, and participant age. Transformations of each variable, as well as break point analysis were considered. Prediction errors were reduced by 77.7–80.6% for sedentary behavior and 61.3–98.6% for physical activity by using the multivariable linear regression models over raw questionnaire scores. Conclusions This research demonstrates the utility of calibrating self-report questionnaire data to objective measures to improve estimates of physical activity and sedentary behavior. It provides an understanding of the divide between objective and subjective measures, and provides a means to utilize the two methods as a unified measure.

Goals The goal of this study is to examine the causes, type of adverse events (AE), and effects of elective intubation in outcomes associated with esophageal food impaction (EFI). Background EFI is a gastrointestinal emergency requiring immediate medical attention. Study Retrospective review of all EFI cases presenting at 3 large tertiary centers from October 1, 2011 to October 31, 2014 and all cases registered in the Clinical Outcome Research Initiative (CORI) database from January 1, 2000 to December 31, 2012. Statistical analysis compared health care utilization, AEs, and outcomes in patients with or without elective intubation. Results A total of 214 cases presenting with EFI at our 3 referral hospitals and 4950 cases in the CORI database met inclusion criteria. Prevalence of structural disorders was similar in the Mayo Clinic and CORI datasets: 24.3% and 27.7% had strictures, and 3.8% and 2.5% had a tumor, respectively. AEs in the nonintubation group were 14.7% compared with 33.3% in the elective intubation group (P=0.003); however, 71.0% of these events were associated with EFI itself and not therapeutic procedure. Esophageal AEs were common (15.0%), followed by pulmonary and cardiovascular events with 3.0% and 1.4%, respectively. Severity of the AEs was influenced by the impaction-to-endoscopy time. Conclusions Prevalence of structural esophageal disorders was similar to previous smaller studies. Elective intubation was associated with increased AEs; however, this is felt to be because of the nature of EFI itself and not by therapeutic endoscopy. Prolonged impaction-to-endoscopy time was associated with severe AEs.

To understand what children with type 1 diabetes in a representative tertiary hospital clinic are eating compared to their peers and explore dietary intake impact on HbA1c outcome. An open cross-sectional dietary audit of children and adolescents with diabetes aged 2–17 years attending the Royal Children’s Hospital, Melbourne was conducted using an age-appropriate validated Food Frequency Questionnaire. Total energy, macronutrient intake and diet quality were calculated and compared to dietary advice provided and national intake data. Body weight, and dietary intake influences on glycaemic control were investigated. Overall, 785 patients were recruited, from which 429 dietary surveys were completed. Dietary intakes were overall nutritionally adequate with macronutrient distribution (% total energy intake) being lower carbohydrate (48.6%), higher total sugars (22.4%), fat (32.9%), saturated fat (14.9%) and protein intake (19.1%) than recommendations, but similar to their peers. Energy intakes were excessive compared to their peers in the 4–13 year olds. Rates of overweight (30%) were significantly higher than national data (18%). Overall, 43% achieved optimal glycaemic control (HbA1c

Introduction and Aims This paper reports on the evaluation of an Australian whole-of-community social marketing intervention targeting social norms, which aimed to reduce inflated perceptions of the prevalence of underage drinking and increase the age at which alcohol initiation is considered acceptable. Design and Methods A community-wide intervention was delivered in a single community over a period of 2 years, targeting adolescents, parents and community members. Pre-and post-intervention computer-assisted telephone interview surveys were conducted in the intervention and a matched comparison (control) community. A total of 417 respondents completed both surveys (215 in the intervention community and 202 in the control community). Results The intervention community saw an increase of 6 months in the average age at which it is perceived to be acceptable for young people to have a sip/taste of alcohol and 5 months in the average age at which it is perceived to be acceptable to have weak/watered down alcohol. Furthermore, there was a reduction in the perception of the prevalence of alcohol consumption by young people to a level consistent with actual underage drinking rates. In comparison, the control community saw no change in any of these variables. Discussion and Conclusions This study provides preliminary evidence that a whole-of-community social marketing intervention can change perceptions of the prevalence, and acceptability, of underage drinking. Given the central role of social norms in decisions regarding alcohol consumption, these changes have the potential to reduce parental supply and thus underage drinking.

Aims To examine the association of alcohol-brand social networking pages and Facebook users' drinking attitudes and behaviours. Methods Cross-sectional, self-report data were obtained from a convenience sample of 283 Australian Facebook users aged 16–24 years via an online survey. Results More than half of the respondents reported using Facebook for more than an hour daily. While only 20% had actively interacted with an alcohol brand on Facebook, we found a significant association between this active interaction and alcohol consumption, and a strong association between engagement with alcohol brands on Facebook and problematic drinking. Conclusions The findings of this study demonstrate the need for further research into the complex interaction between social networking and alcohol consumption, and add support to calls for effective regulation of alcohol marketing on social network platforms.

To assess association between lower body muscle power and bone strength as well as the mediating effect of muscle cross-sectional area (MCSA) on that association.Participants (141 males and 162 females) were approximately 17 yr. Muscle power was predicted using vertical jump and the Sayers equation. Using peripheral quantitative computed tomography (pQCT), bone strength indices were obtained at two locations of the tibia, corresponding to primary stressors acting upon each site: bone strength index for compression (BSI) at the distal 4% site; density-weighted polar section modulus strength-strain index (SSIp) and cortical bone area (CoA) at the 66% midshaft site for torsion. Muscle cross-sectional area was measured at the 66% site. Pearson bivariate and partial correlation coefficients were estimated to quantify the strength of the associations among variables. Direct and indirect mediation model effects were estimated, and 95% bootstrap confidence intervals were constructed to test the causal hypothesis. Height and maturity were examined as covariates.Pearson correlation coefficients among muscle power, MCSA, and bone strength were statistically significant (P0.01) and ranged from r = 0.54 to r = 0.78. After adjustment for covariates, associations were reduced (r = 0.37 to 0.69) (P0.01). Mediation models for males for BSI, SSIp, and CoA accounted for 38%, 66%, and 54% of the variance in bone strength, respectively. Models for females for BSI, SSIp, and CoA accounted for 46%, 77%, and 66% of the variance, respectively.We found strong and consistent associations as well as direct and indirect pathways, among muscle power, MCSA, and tibia strength. These results support the use of muscle power as a component of health-related fitness in bone health interventions for older adolescents.

The objective of this study was to investigate sacral electrical stimulation (SES) and gastric electrical stimulation (GES) by comparing upper and lower gastrointestinal (GI) and genitourinary (GU) symptoms and quality of life, before treatment and in the long term after treatment. We hypothesized that dual-device treatment would greatly improve upper and lower gastrointestinal and genitourinary symptoms, as well as quality of life. Fifty-four patients who underwent dual-device treatment (GES and SES) were enrolled in this study. Patients who had surpassed 24 months since the second-device insertion were included. Patients were evaluated before and after both devices were implanted and given a symptom questionnaire regarding their upper GI, lower GI, and GU symptoms and their quality of life. With combined treatment, a statistically significant improvement was seen in upper GI, lower GI, and GU symptoms and quality of life. However, fecal incontinence and fecal urgency improvements did not reach statistical significance, likely due to the small sample size. The implantation of two stimulators appears to be safe and effective to improve patients’ quality of life for those with upper GI symptoms, bowel problems, and bladder dysfunction.

Background Many internal medicine (IM) programs have reorganized their resident continuity clinics to improve trainees' ambulatory experience. Downstream effects on continuity of care and other clinical and educational metrics are unclear. Methods This multi-institutional, cross-sectional study included 713 IM residents from 12 programs. Continuity was measured using the usual provider of care method (UPC) and the continuity for physician method (PHY). Three clinic models (traditional, block, and combination) were compared using analysis of covariance. Multivariable linear regression analysis was used to analyze the effect of practice metrics and clinic model on continuity. Results UPC, reflecting continuity from the patient perspective, was significantly different, and was highest in the block model, midrange in combination model, and lowest in the traditional model programs. PHY, reflecting continuity from the perspective of the resident provider, was significantly lower in the block model than in combination and traditional programs. Panel size, ambulatory workload, utilization, number of clinics attended in the study period, and clinic model together accounted for 62% of the variation found in UPC and 26% of the variation found in PHY. Conclusions Clinic model appeared to have a significant effect on continuity measured from both the patient and resident perspectives. Continuity requires balance between provider availability and demand for services. Optimizing this balance to maximize resident education, and the health of the population served, will require consideration of relevant local factors and priorities in addition to the clinic model.

U.S. older adults are not meeting the recommendation for whole grain (WG) intake. This pilot study determined the influence that a WG nutrition education program for community-residing adults aged 60 + years has on WG knowledge and behaviors. The program included WG education and discussion, participation in hands-on activities and taste testing. Participants were mostly white, females. Total grain and WG dietary intake frequencies (WG frequency; p ≤ 0.001), and “knowledge score” increased from PRE to POST (p ≤ 0.001). Participants in PowerPoint-based classes had a higher “knowledge scores” at POST (p = 0.002). Nearly all (n = 139, 88.5%) intended to eat more WG foods, with almost two-thirds (n = 93, 59.3%) reporting a “strong” intention to do so. There was a positive association between strength of intention to eat WG foods and “WG frequency” at POST (r = 0.435, p ≤ 0.001). Results suggest that this WG program is an effective strategy for improving WG knowledge and behaviors among older adults.

Research suggests that African migrants are often positively predisposed towards blood donation, but are under-represented in participation. A culturally-tailored intervention targeting the African migrant community in Australia was developed and implemented, to enhance knowledge about blood donation, improve attitudes towards donating, increase intentions to donate blood, and increase the number of new African donors in Australia. Four weeks after a targeted campaign, a survey evaluation process commenced, administered face-to-face by bilingual interviewers from the African community in Melbourne and Adelaide, Australia (community survey). The questionnaires covered demographics, campaign awareness, blood donation knowledge and intentions, medical mistrust and perceived discrimination, and were analysed to evaluate changes in knowledge and intention. Sixty-two percent of survey participants (n = 454) reported being aware of the campaign. With increasing campaign awareness, there was a 0.28 increase in knowledge score (p = .005); previous blood donation was also associated with an increased blood donation knowledge score. Blood donation intention scores were not associated with campaign awareness (p = 0.272), but were associated with previous blood donation behaviour and a positive blood donation attitude score. More positive scores on the blood donation attitude measure were associated with increasing blood donation intentions, self-efficacy and campaign awareness (score increases of 0.27, 0.30 and 0.04, respectively, all p

Community planners such as policymakers and health care and nutrition service providers can create an "age-friendly" environment to support healthy eating in older residents by addressing the highest priorities that enable older adults to improve their dietary intake through different food-related community settings. To identify and prioritize these factors that facilitate behavioral change (enablers) and behavioral settings important for older adult nutrition based on the social ecological model, nutrition and aging professionals (n = 30) from two rural (West Virginia, Iowa) and two urban (Massachusetts, New York) city/county regions (communities) participated in an online or live focus group discussion and completed an analytic hierarchy process survey online. Overall, the most important perceived enablers were accessibility and cost, followed by transportation and social support, but their relative importance varied by community. Participants from all communities considered congregate meal sites and food banks among the most important behavioral settings. Participants from most communities considered food stores to be important and also highlighted other settings unique to the area, such as senior housing, neighborhood, and farmers' markets. By targeting interventions to address the most notable enablers and behavioral settings specific to their community, planning groups can enhance their older residents' ability to achieve optimal nutritional health.

Previous studies have shown that some lipoglycopeptide and lipopeptide antimicrobial agents may cause falsely elevated values for some phospholipid-dependent coagulation tests. The effect of oritavancin, a lipoglycopeptide antibiotic, on coagulation test results was explored using pooled human plasma samples spiked with drug and in a clinical study after an infusion of a single 1,200-mg intravenous dose of oritavancin in normal healthy volunteers. Pooled plasma with oritavancin added ex vivo showed concentration-dependent prolongation of prothrombin time/international normalized ratio (PT/INR), activated partial thromboplastin time (aPTT), and dilute Russell viper venom time (DRVVT) test results. In contrast, oritavancin had no effect on the activated protein C resistance assay, chromogenic anti-factor Xa assay (anti-FXa), thrombin time, and an immunoassay for the laboratory diagnosis of heparin-induced thrombocytopenia. In participants that received a single dose of oritavancin, elevations in PT/INR result, aPTT, DRVVT, activated clotting time, and silica clotting time occurred, with the maximum times to resolution of test interference determined to be 12, 120, 72, 24, and 18 h, respectively. The anti-FXa assay was unaffected, whereas transient elevations in D dimer levels were observed in 30% of participants, with a maximum time to resolution of 72 h. Although oritavancin has no impact on the coagulation system in vivo , a single dose of oritavancin can produce falsely elevated values of some coagulation tests used to monitor hemostasis. The interference of oritavancin on affected tests is transient, and the test results revert to normal ranges within specified times after dosing.

Sialadenitis in the pediatric population accounts for up to 10% of all salivary gland disease. Viral parotitis and juvenile recurrent parotitis are the two most common causes. Multiple factors, independently or in combination, can result in acute, chronic, or recurrent acute salivary gland inflammation. Sialendoscopy has emerged as the leading diagnostic technique and intervention for pediatric sialadenitis. Sialendoscopy is a safe and effective gland-preserving treatment of pediatric sialadenitis. Investigational studies are needed to address the impact of steroid instillation, postoperative stenting, and long-term outcomes of pediatric sialendoscopy. This article presents a comprehensive review of pathophysiology, clinical presentation, diagnosis, and treatment of pediatric sialadenitis.
