Abstract Background Comparison of data produced on different microarray platforms often shows surprising discordance. It is not clear whether this discrepancy is caused by noisy data or by improper probe matching between platforms. We investigated whether the significant level of inconsistency between results produced by alternative gene expression microarray platforms could be reduced by stringent sequence matching of microarray probes. We mapped the short oligo probes of the Affymetrix platform onto cDNA clones of the Stanford microarray platform. Affymetrix probes were reassigned to redefined probe sets if they mapped to the same cDNA clone sequence, regardless of the original manufacturer-defined grouping. The NCI-60 gene expression profiles produced by Affymetrix HuFL platform were recalculated using these redefined probe sets and compared to previously published cDNA measurements of the same panel of RNA samples. Results The redefined probe sets displayed a substantially higher level of cross-platform consistency at the level of gene correlation, cell line correlation and unsupervised hierarchical clustering. The same strategy allowed an almost complete correspondence of breast cancer subtype classification between Affymetrix gene chip and cDNA microarray derived gene expression data, and gave an increased level of similarity between normal lung derived gene expression profiles using the two technologies. In total, two Affymetrix gene-chip platforms were remapped to three cDNA platforms in the various cross-platform analyses, resulting in improved concordance in each case. Conclusion We have shown that probes which target overlapping transcript sequence regions on cDNA microarrays and Affymetrix gene-chips exhibit a greater level of concordance than the corresponding Unigene or sequence matched features. This method will be useful for the integrated analysis of gene expression data generated by multiple disparate measurement platforms.

- Abstract
Many residents in Skilled Nursing Facilities (SNFs) present with dysphagia and receive altered diets or liquids to minimize the risk of complications. Limited access to timely instrumental evaluations of swallow may impede the best management of these dysphagic residents. De-identified FEES reports completed by a mobile FEES company during a single month, January 2019, were reviewed. Descriptive statistics were used to summarize the pre-study diet/liquid levels and the post-study diet/liquid recommendations. FEES reports (n = 952) were reviewed. Before the FEES evaluation, 209 residents were receiving only non-oral nutrition. After the FEES evaluation, 76% of these residents were recommended to receive oral nutrition. Before the FEES evaluation, 442 (46%) residents were receiving thickened liquids, after the FEES evaluation, 244 (26%) were recommended to have a less restrictive liquid level. Before the FEES evaluation, 576 (60%) residents were receiving altered food texture, after the FEES evaluation, 413 (43%) were recommended to have a less restrictive food texture. The percentage of residents recommended to receive thin liquids increased from 32 to 68% and those recommended to receive a regular diet increased from 18 to 34%. These data indicate that access to instrumental swallow evaluations in the SNF setting generally resulted in lifting liquid and diet restrictions for many residents in the cohort reviewed and potentially improved their quality of life., (© 2024.

- Abstract
Background: Estimating program costs when planning community-based mental health programs can be burdensome. Our aim was to retrospectively document the cost for the first year of planning and implementing Healthy Minds Healthy Communities (HMHC), a mental health promotion and prevention multi-level intervention initiative. This Program is among the first to use the Community Initiated Care (CIC) model in the US and is aimed at building community resilience and the capacity for communities to provide mental health support, particularly among those disproportionately impacted by COVID-19. Our objective is to share our methods for costing a program targeting 10 zip codes that are ethnically and linguistically diverse and provide an example for estimating the cost of a mental health prevention and promotion programs consisting of multiple evidence-based interventions., Methods: We used a semi-structured interview process to collect cost data through the first year of program planning, start-up and initial implementation from key staff. We calculated costs for each activity, grouped them by major project categories, and identified the cost drivers of each category. We further validated cost estimates through extensive literature review. The cost analysis was done from the provider's perspective, which included the implementing agency and its community partners. We delineated costs that were in-kind contributions to the program by other agency, and community partners. Sensitivity analyses were conducted to estimate uncertainty around parameters., Results: For the first year of the development and implementation of the program, (funded through program and in-kind) is estimated at $1,382,669 (2022 US$). The costs for the three main activity domains for this project are: project management $135,822, community engagement $364,216 and design and execution $756,934. Overall, the cost drivers for the first year of this intervention were: hiring and onboarding staff, in-person community building/learning sessions, communications and marketing, and intervention delivery., Conclusion: Implementation of community-based mental health promotion and prevention programs, when utilizing a participatory approach, requires a significant amount of upfront investment in program planning and development. A large proportion of this investment tends to be human capital input. Developing partnerships is a successful strategy for defraying costs., (© 2024. The Author(s).)

- Abstract
Introduction: Calcitonin gene-related peptide (CGRP) plays an important role in cerebral vasodilation, so here we aim to quantify the impact of CGRP monoclonal antibody (mAb) therapy on cerebral hemodynamics., Methods: In 23 patients with chronic and episodic migraine, cerebral hemodynamic monitoring was performed (1) prior to and (2) 3-months into CGRP-mAb therapy. Transcranial Doppler monitored cerebral blood flow velocity (CBFv) in the middle cerebral artery (MCA) and posterior cerebral artery (PCA), from which cerebrovascular reactivity (CVR) and cerebral autoregulation (CA; Mx-index ) were calculated., Results: CA was similar off and on treatment, in the MCA ( p = 0.42) and PCA ( p = 0.72). CVR was also unaffected by treatment, in the MCA ( p = 0.38) and PCA ( p = 0.92). CBFv and blood pressure were also unaffected. The subgroup of clinical responders (>50% reduction in migraine frequency) exhibited a small reduction in MCA-CBFv (6.0 cm/s; IQR: 1.1-12.4; p = 0.007) and PCA-CBFv (8.9 cm/s; IQR: 6.9-10.3; p = 0.04)., Discussion: Dynamic measures of cerebrovascular physiology were preserved after 3 months of CGRP-mAb therapy, but a small reduction in CBFv was observed in patients who responded to treatment. Subgroup findings should be interpreted cautiously, but further investigation may clarify if CBFv is dependent on the degree of CGRP inhibition or may serve as a biomarker of drug sensitivity., Competing Interests: EK received royalties from patents in association with Alder Biopharmaceuticals related to anti-CGRP monoclonal antibodies for the treatment of migraine and photophobia and received investigator-driven grant funding from Amgen, which manufactures an anti-CGRP monoclonal antibody for the treatment of migraine and not used for this study. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Carter, Cucchiara, Reehal, Hamilton, Kaiser and Favilla.)

- Abstract
Background: Accurate blood pressure (BP) measurement remains challenging in patients with HeartMate 3™ left ventricular assist devices (HM3 LVADs). The Finapres® NOVA is a promising non-invasive continuous BP monitor that uses the volume clamp method via a finger cuff, so here we aimed to validate the instrument in HM3 patients., Methods: In a single-center cohort, BP was monitored in 15 patients within 72 h following HM3 implantation. A radial artery catheter quantified arterial blood pressure (ABP), while the NOVA measured finger arterial pressure (fiAP) and reconstructed brachial artery pressure (reBAP). Waveforms were recorded for 10 min, and mean values were calculated in 15-s intervals., Resuts: fiAP and ABP were moderately correlated during both the first (ICC 0.61, p = 0.04) and final measurements (ICC 0.66, p = 0.03). reBAP and ABP were strongly correlated during both the first (ICC 0.81, p = 0.002) and final measurements (ICC 0.83, p = 0.001). Both NOVA-derived values may underestimate low BP values while overestimating relatively high BP values. The reBAP was within 5 mm Hg of the ABP in 40% of patients (and within 10 mm Hg in 67%)., Conclusions: This pilot represents the first evidence in support of the Finapres® NOVA for non-invasive BP measurement in select patients with HM3 LVADs. The instrument may provide useful data during BP medication adjustments or pump titration, but despite the correlation between the non-invasive reBAP and invasive ABP, individual-level inaccuracy may be clinically meaningful. Further investigation is needed to clarify these limitations and optimize accuracy before widespread adoption in this unique patient population., (© 2023 International Center for Artificial Organ and Transplantation (ICAOT) and Wiley Periodicals LLC.)

- Abstract
Objective: To assess barium esophagram (BAS) as a diagnostic marker for patients with Killian Jamieson diverticula (KJD)., Methods: Prospective, multicenter cohort study of individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative. Patient demographics, comorbidities, radiographic imaging reports, laryngoscopy findings, patient-reported outcome measures (PROM), and operative reporting were abstracted from a REDCap database and summarized using means, medians, percentages, frequencies. Paired t-tests and Wilcoxon Signed Rank test were used to test pre- to post-operative differences in RSI, EAT-10, and VHI-10 scores. Diagnostic test evaluation including sensitivity, specificity, positive, and negative predictive value with 95% confidence intervals were calculated comparing BAS findings to operative report., Results: A total of 287 persons were enrolled; 13 (4%) patients were identified with confirmed KJD on operative reports. 100% underwent open transcervical excision. BAS has a 46.2% (95% confidence interval [CI]: 23.2, 70.9) sensitivity and 97.8% (95% CI: 95.3, 99.0) specificity in detecting a KJD and 50% (95% CI: 25.4, 74.6) positive predictive value but 97.4% (95%CI: 94.8, 98.7) negative predictive value. Preoperatively, patients reported mean (SD) RSI and EAT-10 of 19.4 (9) and 8.3 (7.5) accordingly. Postoperatively, patients reported mean (SD) RSI and EAT-10 as 5.4 (6.2) and 2.3 (3.3). Both changes in RSI and EAT-10 were statistically significant (p = 0.008, p = 0.03)., Conclusion: KJD are rare and represent <5% of hypopharyngeal diverticula undergoing surgical intervention. Open transcervical surgery significantly improves symptoms of dysphagia. BAS has high specificity but low sensitivity in detecting KJD., Level of Evidence: 4 Laryngoscope, 133:2110-2115, 2023., (© 2022 The Authors.

- Abstract
Purpose: Laryngeal dystonia is a chronic neurologic disorder characterized by intention-induced spasms of the vocal folds driven by aberrant central motor processing. The use of in-office transcervical botulinum toxin injection for the treatment of laryngeal disorders, such as laryngeal dystonia, has been deemed safe and efficacious. There is, however, no available data outlining the hemodynamic changes experienced by patients undergoing this frequently performed procedure., Methods: One hundred and one patients diagnosed with laryngeal dystonia were enrolled in this prospective study. These patients underwent transcervical laryngeal botulinum toxin injection to address their dysphonia. Vital signs where acquired prior to, and at the time of injection. Alterations in these parameters were then evaluated for statistical significance., Results: Statistically significant increases in mean heart rate (5.8 ± 10.8 bpm, P < 0.0001), systolic blood pressure and diastolic blood pressure (7.0 ± 9.5 mm Hg, P < 0.0001; 8.7 ± 14.7 mm Hg, P < 0.0001) were discovered. No statistically significant difference in oxygen saturation was noted and no patients in the study faced major adverse outcomes., Conclusions: Though these findings may not have related to clinically significant complication, our study demonstrates the importance of understanding potential stressors in a procedure routinely performed by laryngologists. This may result in more careful patient selection, alterations in procedure, and improved safety by acting in a timely fashion if alarming changes in hemodynamic parameters are noted., (Copyright © 2021 The Voice Foundation.

- Abstract
Background: Young adults experiencing homelessness (YAEH) experience more stressors compared to housed peers, yet little is known about the impact of the COVID-19 pandemic on these youth. The purpose of this qualitative study was to explore how YAEH perceived the pandemic's impact on their well-being and coping., Methods: YAEH were recruited from those participating in an HIV prevention study. Semi-structured interviews were conducted and analysis was guided by Lazarus and Folkman's transactional theory of stress and coping., Results: Four major themes were identified from interviews with 40 youth: (1) ongoing harms, (2) COVID-19 as a stressor, (3) mental health impacts, and (4) coping strategies. Participants described unmet basic needs, emotions of frustration and anxiety, and several coping strategies including substance use., Conclusion: Many YAEH reported experiencing continued challenges that were compounded by the stressors related to the COVID-19 pandemic. Special considerations are needed to address pandemic-related exacerbations of mental health symptoms and substance use among YAEH., (© 2022 Wiley Periodicals LLC.)

- Abstract
Rationale: The etiology of cystic fibrosis (CF) pulmonary exacerbations (PEx) is likely multifactorial with viral, bacterial, and non-infectious pathways contributing. Objectives: To determine whether viral infection status and CRP (C-reactive protein) can classify subphenotypes of PEx that differ in outcomes and biomarker profiles. Methods: Patients were recruited at time of admission for a PEx. Nasal swabs and sputum samples were collected and processed using the respiratory panel of the FilmArray multiplex polymerase chain reaction (PCR). Serum and plasma biomarkers were measured. PEx were classified using serum CRP and viral PCR: " pauci-inflammatory " if CRP < 5 mg/L, " non-viral with systemic inflammation " if CRP ⩾ 5 mg/L and no viral infection detected by PCR and " viral with systemic inflammation " if CRP ⩾ 5 mg/L and viral infection detected by PCR. Results: Discovery cohort ( n = 59) subphenotype frequencies were 1 ) pauci-inflammatory (37%); 2 ) non-viral with systemic inflammation (41%); and 3 ) viral with systemic inflammation (22%). Immunoglobulin G, immunoglobulin M, interleukin-10, interleukin-13, serum calprotectin, and CRP levels differed across phenotypes. Reduction from baseline in forced expiratory volume in 1 second as percent predicted (FEV
1 pp) at onset of exacerbation differed between non-viral with systemic inflammation and viral with systemic inflammation (-6.73 ± 1.78 vs. -13.5 ± 2.32%; P = 0.025). Non-viral with systemic inflammation PEx had a trend toward longer duration of intravenous antibiotics versus pauci-inflammation (18.1 ± 1.17 vs. 14.8 ± 1.19 days, P = 0.057). There were no differences in percent with lung function recovery to <10% of baseline FEV1 pp. Similar results were seen in local and external validation cohorts comparing a pauci-inflammatory to viral/non-viral inflammatory exacerbation phenotypes. Conclusions: Subphenotypes of CF PEx exist with differences in biomarker profile, clinical presentation, and outcomes.- Published

- Abstract
Invasive alien species (IAS) are a rising threat to biodiversity, national security, and regional economies, with impacts in the hundreds of billions of U.S. dollars annually. Proactive or predictive approaches guided by scientific knowledge are essential to keeping pace with growing impacts of invasions under climate change. Although the rapid development of diverse technologies and approaches has produced tools with the potential to greatly accelerate invasion research and management, innovation has far outpaced implementation and coordination. Technological and methodological syntheses are urgently needed to close the growing implementation gap and facilitate interdisciplinary collaboration and synergy among evolving disciplines. A broad review is necessary to demonstrate the utility and relevance of work in diverse fields to generate actionable science for the ongoing invasion crisis. Here, we review such advances in relevant fields including remote sensing, epidemiology, big data analytics, environmental DNA (eDNA) sampling, genomics, and others, and present a generalized framework for distilling existing and emerging data into products for proactive IAS research and management. This integrated workflow provides a pathway for scientists and practitioners in diverse disciplines to contribute to applied invasion biology in a coordinated, synergistic, and scalable manner., (© 2022 Cambridge Philosophical Society.

- Abstract
Objectives/hypothesis: Few studies address the demographics/epidemiology/socioeconomic status of patients presenting to a laryngologist at a tertiary care center for treatment. To identify any possible disparities in voice, airway, and swallowing care, we sought to analyze the aforementioned data for new patients presenting to the voice center at an academic medical center., Methods: This is a retrospective cohort study of prospectively collected data from an institutional database of 4,623 new adult patients presenting for laryngological care at a tertiary care, academic medical center from 2015 to 2020. Demographic data were analyzed., Results: Of 4,623 patients, 62.8% were female and 37.2% were male with ages ranging from 19 to 99 years (Avg 59.51, standard deviation 15.83). Patients were 81.8% white, 13% black, and 5.2% other, compared with 56.3% white, 34.8% black, 20% other in the local municipality from US Census Data. Payer mix included 46.98% Medicare, 42.59% commercial insurance, 3.22% Medicaid, 5.19% other, and 2.01% uninsured/self-insured. Patient demographics based on primary diagnosis codes were also examined. A majority of patients presented with voice-related complaints., Conclusions: Understanding the demographics of those with laryngological disorders will help to develop targeted interventions and effective outreach programs for underrepresented patient populations. Future multicenter studies could provide further insight into the distribution of healthcare disparities in laryngology., Level of Evidence: 3 Laryngoscope, 132:626-632, 2022., (© 2021 The American Laryngological, Rhinological and Otological Society, Inc.)

- Abstract
Objectives/hypothesis: The Laryngopharyngeal Measure of Perceived Sensation (LUMP) is a recently validated patient-reported outcome measure (PROM) aimed at evaluating the symptom severity of patients with globus pharyngeus (GP). The objective of this study was to define the normative values for the LUMP questionnaire., Study Design: Prospectively collected, descriptive research/scale development., Methods: The LUMP questionnaire was completed by 88 subjects. Individuals without throat-related symptoms such as dysphagia, dysphonia, or cough were provided LUMP. The results of the eight-item questionnaire were analyzed for standard error of the mean (SEM), mean, and standard deviation (SD)., Results: Review of the 88 LUMP questionnaires elucidated a mean of 0.42 (SEM = 0.10, SD = 0.96) in the normative population. By gender, the female (n = 50) mean was 0.24, SD = 0.66, SEM = 0.09; for males (n = 38), the mean was 0.66, SD = 1.21, SEM = 0.20., Conclusions: This study provides normative data for the LUMP, a recently established PROM useful in patients with GP. A LUMP score greater than or equal to 3 should be considered abnormal and warrants additional attention., Level of Evidence: 3 Laryngoscope, 132:398-400, 2022., (© 2021 The American Laryngological, Rhinological and Otological Society, Inc.)

- Abstract
Young adults experiencing homelessness (YAEH) are at high risk for discrimination. Limited research has documented the extent of discrimination experiences and their relationship to mental health outcomes among this group. This study used data from YAEH who completed self-administered surveys across seven U.S. cities ( N = 1,426) to examine the rates and correlates of discrimination experiences and their association with psychological distress and suicidal ideation. Chi-square and multivariate logistic regressions were used to examine the relations between perceived discrimination and race, gender identity, sexual orientation, foster care history, criminal justice history, reasons for homelessness, and length of time homeless. Then, logistic regression was used to examine whether discrimination increased the odds of psychological distress and suicidal ideation, controlling for other factors. Three-fourths (75.8%) of the sample ( n = 1,055) reported experiencing at least one of the five forms of everyday discrimination experiences at least a few times a year, with the most common reason attributed to their housing situation (46%). Sexual orientation, juvenile justice involvement, and having been homeless for 2 years or more were associated with increased odds of experiencing discrimination. Discrimination was a strong predictor of psychological distress but was significant only at the bivariate level for suicidal ideation. Study results suggest that experiences of discrimination are common among YAEH and that these experiences increase risk for psychological distress. Providers working with YAEH need to validate and acknowledge the impact of these experiences on mental health. And, communities need to work to reduce discrimination experiences by targeting stigma against YAEH. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

- Abstract
We examine the challenges formerly homeless young adults (FHYAs) face after they transition out of homelessness. Considering the adversities FHYAs face, it is unclear how transitioning to stable housing may affect their mental well-being or what types of stressors they may experience once housed. This study investigates the social environment young adults encounter in their transition to stable housing and examines trauma and social coping predictors of mental health symptoms in a sample of FHYAs to generate new knowledge for better intervening to meet their needs. Data were obtained from REALYST, a national research collaborative comprised of interdisciplinary researchers investigating young adults' (ages 18-26) experiences with homelessness. Cross-sectional data for 1426 young adults experiencing homelessness were collected from 2016 to 2017 across seven cities in the United States (i.e., Los Angeles, Phoenix, Denver, Houston, San Jose, St. Louis, and New York City). The analytical sub-sample for this study consisted of 173 FHYAs who were housed in their own apartment (via voucher from Housing and Urban Development or another source) or in transitional living programs during their participation in the study. Ordinary Least Squares regression was used to examine the influence of trauma and social coping strategies on indicators of mental well-being. Findings indicated that higher adversity scores and higher mental health help-seeking intentions were positively associated with higher levels of stress, psychological distress, and depression severity. Higher level of social coping was associated with lower levels of depression severity. Logistic regression results showed that young adults with higher adversity scores had higher odds of reporting clinical levels of post-traumatic symptoms. The study implications suggest that FHYAs who transition to stable housing continue to need support navigating and coping with stressful life events; and interventions that help FHYAs develop strong networks of social supports are needed to promote positive mental well-being., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, funding, authorship, and/or publication of this article., (© 2021 Published by Elsevier Ltd.)

- Abstract
This study provides regional-scale data on drivers of horseshoe crab (Limulus polyphemus) presence along the northcentral Gulf of Mexico coast and has implications for understanding habitat suitability for sparse horseshoe crab populations of conservation concern worldwide. To collect baseline data on the relationship between environmental factors and presence of horseshoe crabs, we surveyed four sites from the Fort Morgan peninsula of Mobile Bay, Alabama (AL) to Horn Island, Mississippi (MS). We documented number, size and sex of live animals, molts, and carcasses as metrics of horseshoe crab presence and demographics for two years. Data were compared to in situ and remotely sensed environmental attributes to assess environmental drivers of occurrence during the time of study. Overall, greater evidence of horseshoe crab presence was found at western sites (Petit Bois and Horn Islands) compared to eastern sites (Dauphin Island, Fort Morgan peninsula), mediated by a combination of distance from areas of high freshwater discharge and interannual variation in weather. Higher sex ratios also were found associated with higher occurrence, west of Mobile Bay. Land cover, particularly Bare Land and Estuarine Emergent Wetland classes that are common to western sites, was most predictive of live animal and to some extent carcass occurrence. Our findings suggest that small-scale variation in habitat quality can affect occurrence of horseshoe crabs in sparse populations where density is not a limiting factor. Data from molts and carcasses were informative to supplement live animal data and may be useful to enhance ecological assessment and support conservation and management in regions with sparse populations., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Objective: To determine the effects of globus pallidus interna (GPi) deep brain stimulation (DBS) on speech and voice quality of patients with primary, medically refractory dystonia., Methods: Voices of 14 patients aged ≥18 years (males = 7 and females = 7) with primary dystonia (DYT1 gene mutation dystonia = 4, cervical dystonia = 6, and generalized dystonia = 4) with bilateral GPi DBS were assessed. Five blinded raters (two fellowship-trained laryngologists and three speech/language pathologists) evaluated audio recordings of each patient pre- and post-DBS. Perceptual voice quality was rated using the Grade, Roughness, Breathiness, Asthenia, and Strain scale and changes in speech intelligibility were assessed with the Clinical Global Impression scale of Severity instrument. Inter-rater and intrarater reliability rates for perceptual voice ratings were assessed using the kappa coefficient., Results: Voice quality parameters showed mean improvements in Grade (P < 0.0001), Roughness (P = 0.0043), and Strain (P < 0.0001) 12 months post-DBS. Asthenia increased from baseline to 6 months (P = 0.0022) and declined significantly from 6 to 12 months (P = 0.0170). Breathiness did not change significantly over time. Speech intelligibility also improved from 6 to 12 months (P = 0.0202) and from pre-DBS to 12 months post-DBS (P = 0.0022). Grade and Strain ratings had nearly perfect and substantial inter-rater agreement (0.84 and 0.71, respectively)., Conclusions: Voice and speech intelligibility improved after bilateral GPi DBS for dystonia. GPi DBS may emerge as a potential treatment option for patients with medically refractory laryngeal dystonia., (Copyright © 2019 The Voice Foundation. Published by Elsevier Inc. All rights reserved.)

- Abstract
The aetiology of bacterial vaginosis (BV) is not well-understood, and prevalence appears to be higher among women living in sub-Saharan Africa. A recent conceptual model implicates three main bacteria ( Gardnerella vaginalis; Atopobium vaginae; and Prevotella bivia ), sexual activity, sialidase activity, and biofilm formation in the pathogenesis of BV. We describe the vaginal microbiota, presence of the putative sialidase A gene of G. vaginalis , and biofilm among 386 adolescent girls aged 17 and 18 years in a cross-sectional study in Mwanza, Tanzania around the time of expected sexual debut. Vaginal swabs were collected and tested by quantitative polymerase chain reaction (qPCR) for five Lactobacillus species, G. vaginalis, A. vaginae, P. bivia , the sialidase A gene of G. vaginalis , and by fluorescence in situ hybridisation (FISH) for evidence of G. vaginalis and A. vaginae biofilm. We conducted a risk factor analysis of G. vaginalis, A. vaginae and P. bivia , and explored the associations between biofilm, the presence of the sialidase A gene, and non-optimal vaginal microbiota (Nugent 4-7) . L. crispatus and L. iners were detected in 69 and 82% of girls, respectively. The prevalence of L. crispatus was higher than previously reported in earlier studies among East and Southern African women. G. vaginalis, A. vaginae, P. bivia were independently associated with reported penile-vaginal sex. Samples with all three BV-associated bacteria made up the highest proportion of samples with Nugent-BV compared to samples with each bacterium alone or together in pairs. Of the 238 girls with G. vaginalis , 63% had the sialidase A gene detected, though there was no difference by reported sexual activity ( p = 0.197). Of the 191 girls with results for sialidase A gene and FISH, there was strong evidence for an increased presence of sialidase A gene among those with evidence of a biofilm ( p < 0.001). There was a strong association between biofilm and non-optimal microbiota (aOR67.00; 95% CI 26.72-190.53). These results support several of the steps outlined in the conceptual model, although the role of sexual activity is less clear. We recommend longitudinal studies to better understand changes in vaginal microbiota and biofilm formation around the time of sexual debut., (Copyright © 2020 Francis, Crucitti, Smekens, Hansen, Andreasen, Jespers, Hardy, Irani, Changalucha, Baisley, Hayes, Watson-Jones and Buvé.)

- Abstract
Objective: Trials testing promising interventions in knee osteoarthritis (OA) often fail to show pain reductions. This may be due to change in activity whereby a person's pain decreases, leading them to increase their activity levels, in turn increasing pain back to baseline levels. Using data from a trial of a beneficial treatment for knee pain, we explored whether activity changes might mask a treatment's effect on pain, by looking at whether activity levels increased with effective treatment and whether change in activity level related to change in pain., Design: During the InRespond trial (ISRCTN55059760) participants wore an accelerometer for 7 days before and during treatments. We assessed change in pain on treatment using scores for overall knee pain and pain in a nominated pain-aggravating activity both in the last week and evaluated change in different types of activity using accelerometer data. Principal components analysis tested whether change in activity and pain outcomes were correlated and created composites combining them. We then tested whether activity, pain or the composites showed a treatment effect, and examined their responsiveness., Results: In the 61 participants (mean age 64.5 years, 38% women, mean overall knee pain score 5.08 (0-10)), activity levels mostly decreased during the trial. Principal component analyses suggested that pain and activity did not correlate highly, loading on different components. Treatment that showed significant effects on pain did not show similar effects on either activity (e.g. the active treatment had a slightly greater reduction in total steps taken than the control treatment (difference 1942.6 steps/week, p = 0.42) nor on composites combining activity and pain. Pain outcomes were the most responsive; static loading (standing) outcomes were the most responsive activity outcome., Conclusion: We found no evidence to support the hypothesis that activity levels increase during effective OA treatment and might account for the negligible pain effects of OA treatments., (© 2020 The Authors.)

- Abstract
Background: Approximately one-third of falls are caused by the swing foot contacting an object or the ground, resulting in a trip. The increased incidence of trip-related falls among older adults may be explained by greater within-person minimum toe clearance (MTC) variability., Research Question: Will kinematic variability at any of the 6 major joints in the lower limbs, individually or in combination, be associated with MTC variability?, Methods: This cross-sectional study investigated whether single or multiple joint movements best explained MTC variability in older adults. Twenty healthy older adults (7 males, 13 females; mean age = 71.3 ± 7.2 years) were recruited. Participants were fitted with a modified Cleveland Clinic marker set and walked for 50 trials at self-selected speeds over a 7-meter walkway (with a rest at 25 trials) while 6 infrared cameras recorded kinematics., Results: Seven joint movements were evaluated, and swing hip flexion-extension variability was the only joint movement significantly associated with MTC variability (r = 0.577, p = 0.008) and explained 29.6% (adjusted R
2 ) of the variance of MTC variability in older adults (F (1, 18) = 8.897, p = 0.008)., Significance: Identifying the joint movement/s associated with inconsistencies in toe clearance will improve our understanding of endpoint control in older adults and may lead to the development of effective trip prevention strategies., (Copyright © 2019 Elsevier B.V.

- Abstract
Research has shown that how people think about their health (or illnesses) shapes their help-seeking behavior. In this mixed-methods study, we employed a simultaneous concurrent design to explore the perceptions of mental illness among an understudied population: marginalized young adults. Participants were 60 young adults (ages 18-25) who had experienced mood disorders and used multiple public systems of care during their childhoods. Semistructured interviews were conducted to understand participants' illness and treatment experiences during the transition to adulthood. A team of analysts used constant comparison to develop a codebook of the qualitative themes, and quantitative data were examined using SAS 9.3. Findings suggest that some theoretical categories identified in past illness-perceptions frameworks are salient to marginalized young adults (e.g., identity, management-or control-of symptoms), but both the developmental transition to adulthood and experiences with public systems of care add nuanced variations to illness and treatment perceptions. Our study demonstrates that young adults possess a set of beliefs and emotions about their mental health and help-seeking options that need to be better understood to improve engagement and quality of mental health care for this population. Implications for practice, research, and policy are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

- Abstract
Background: Although rheumatology nursing has been shown to be effective in managing patients with rheumatoid arthritis, patient outcomes sensitive to nursing interventions (nursing sensitive outcomes) have not been systematically studied., Objectives: The objective of this study was to identify and delineate relevant patient outcomes measured in studies that reported nursing interventions in patients with rheumatoid arthritis., Design: A systematic search was conducted from 1990 to 2016. Inclusion criteria were (i) patients with rheumatoid arthritis, (ii) adult population age ≥16years, (iii) nurse as part of the care team or intervention delivery, (iv) primary research only, (v) English language, and (vi) quantitative studies with nursing sensitive outcomes., Data Sources: Medline, CINAHL, Ovid nursing, Cochrane library and PsycINFO databases were searched for relevant studies., Review Methods: Using the predetermined inclusion/exclusion criteria, nine reviewers working in pairs assessed the eligibility of the identified studies based on titles and abstracts. Papers meeting the inclusion criteria were retrieved and full texts were further assessed. Critical Appraisal Skills Programme tools were used to assess the quality of the included studies. Data on nursing sensitive outcomes were extracted independently by two reviewers. The Outcome Measures in Rheumatology comprehensive conceptual framework for health was used to contextualise and present findings., Results: Of the 820 articles retrieved, 7 randomised controlled trials and 3 observational studies met the inclusion criteria. Seventeen nursing sensitive outcomes were identified (disease activity, clinical effects, pain, early morning stiffness duration, fatigue, patient safety issues, function, knowledge, patient satisfaction, confidence in care received, mental health status, self-efficacy, patient attitude/perception of ability to control arthritis, quality of life, health utility, health care resources, death). These fitted into 10 health intervention domains in keeping with the pre-specified conceptual framework for health: disease status, effectiveness, safety, function, knowledge, satisfaction, psychological status, quality of life, cost, death. A total of 59 measurement instruments were identified comprising patient reported outcome measures (n=31), and biologic measures and reports (n=28)., Conclusions: This review is notable in that it is the first to have identified, and reported, a set of multidimensional outcome measures that are sensitive to nursing interventions in rheumatology specifically. Further research is required to determine a core set of outcomes to be used in all rheumatology nursing intervention studies., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

- Abstract
This study qualitatively explored the past treatment experiences of uninsured young adults who sought public emergency psychiatric care. Qualitative interviews were conducted with a racially diverse sample of 55 young adults (ages 18-25) using a semi-structured interview guide, and analyzed using a team-based open coding approach. Findings emerged in three broad areas-provider-related factors, treatment-related factors, and environmental factors. Young adults talked about the importance of providers respecting and listening to them, the perceived advantages and disadvantages of therapy and medication treatment, and aspects of the environment that resulted in positive and negative experiences, particularly in inpatient settings. Providers need to convey respect and caring that transcends job duties and provide tangible skills and supports.

- Abstract
Background: Youth experiencing homelessness have elevated rates of mental illness and substance use compared to the general population. However, the extent to which underlying mental health issues may contribute to substance use as a way to manage symptoms and whether mental health treatment may reduce risk for substance use is unclear. This paper investigated these relations in a community sample of homeless youth., Methods: Youth ages 13-24 (N=416) were interviewed as part of a community count and survey of homeless youth in Houston, Texas. A path analysis examined relations among lifetime diagnoses of ADHD, bipolar disorder, and depression; past-month marijuana, alcohol, and synthetic marijuana use, and hypothesized mediators of past-year mental health treatment and perceived unmet need for treatment., Results: Rates of prior mental disorder diagnoses were high, with extensive comorbidity across the three diagnoses (n=114, 27.3% had all three diagnoses). Relations varied by diagnoses and substances. ADHD was positively related to current marijuana use (β=0.55 (0.16), p<0.001), a relation that mental health treatment did not mediate. Depression was positively related to synthetic marijuana use through unmet need (β=0.25 (0.09), p=0.004) and to alcohol use through unmet need (β=0.20 (0.10), p=0.04) CONCLUSIONS: This study provides new information about relations between prior mental health diagnoses and substance use in homeless youth. Findings support the need to consider prior mental disorder diagnoses in relation to current substance use and to assess for whether youth perceive they have unmet needs for mental health treatment., (Copyright © 2017 Elsevier B.V.

- Abstract
Young adults have low rates of outpatient service utilization and higher rates of emergency service use compared to older adults. This study explored pathways to crisis service use for uninsured young adults who accessed emergency psychiatric treatment. Participants were 55 young adults (ages 18-25) who were on an inpatient short-term stabilization unit and had qualifying diagnoses for outpatient services (bipolar, major depression, or schizophrenia). Semistructured qualitative interviews were conducted to understand decision-making and the events that led to service use. A team of coders used an open coding approach to develop a codebook and participated in iterative discussions of coded text to generate results presented. Themes across 3 dimensions were identified. Participants formed the intention to seek treatment through the interaction of escalating symptoms, triggering events, and motivating factors. Intention was translated to actualized service use through individual and systemic facilitators. Natural supports and service systems influenced the entire process. Findings highlight the importance of understanding motivating factors to better engage young people in treatment and including their support systems in efforts to increase awareness of problems and treatments. Systemic barriers identified suggest the need for enhanced coordination of care across systems such as drug and alcohol treatment, homeless services, and criminal justice and for ready access to outpatient services to reduce crisis psychiatric service use.

- Abstract
Objective: This study examined mental health service use among three groups of young adults with assessed psychological distress: no perceived need for treatment, reported unmet need, and received treatment., Methods: Data came from participants ages 18 to 25 in the National Survey on Drug Use and Health (2008-2013) who met criteria for psychological distress (N=19,775). Demographic, access-, and need-related predictors of perceived need and treatment group were examined by using multinomial logistic regression., Results: Half the sample did not perceive a need for treatment (51.0%), and only one-third had received treatment (33.7%). White youths were more likely than those from other racial-ethnic groups to perceive a need and to receive treatment. Men were less likely than women to perceive need but equally likely to receive treatment. Higher education and having insurance also predicted treatment receipt., Conclusions: Efforts to increase service utilization among young adults should increase awareness of mental health problems and facilitate access, particularly for racial-ethnic minority groups.

- Abstract
Cystic fibrosis (CF) is genetic autosomal recessive disease caused by reduced or absent function of CFTR protein. Treatments for patients with CF have primarily focused on the downstream end-organ consequences of defective CFTR. Since the discovery of the CFTR gene that causes CF in 1989 there have been tremendous advances in our understanding of the genetics and pathophysiology of CF. This has recently led to the development of new CFTR mutation-specific targeted therapies for select patients with CF. This review will discuss the characteristics of the CFTR gene, the CFTR mutations that cause CF and the new mutation specific pharmacological treatments including gene therapy that are contributing to the dawning of a new era in cystic fibrosis care.

Narendorf SC, Small E, Cardoso JA, Wagner RW, and Jennings SW
- Abstract
Support from research assistants (RAs) is often framed as a resource to facilitate faculty research productivity, yet most assistant professors have received minimal training on how to effectively make use of this resource. This study collected data from a national sample of assistant professors to examine tasks RAs are asked to perform, satisfaction with RA work, challenges in working with RAs, and lessons learned to be successful. Authors used a sequential mixed-methods design, first conducting a Web-based survey with 109 assistant professors in social work schools with doctoral programs, then qualitative interviews with a subset of 13 respondents who volunteered to talk more about their experiences. Evidence indicated low levels of satisfaction regarding the preparation of students for RA work, particularly among those assistant professors working with first-year doctoral students. Primary challenges included lack of student skills and commitment and sufficient time to supervise and train students. Recommendations include careful assessment of student skills at the start of the relationship and setting clear expectations. Social work programs can improve faculty-RA relationships by training new assistant professors on how to support and manage RAs and training incoming students on basic research skills for their work as RAs.

- Abstract
Background: Older youth in out-of-home care often live in restrictive settings and face psychiatric issues without sufficient family support. This paper reports on the development and piloting of a manualized treatment foster care program designed to step down older youth with high psychiatric needs from residential programs to treatment foster care homes., Methods: A team of researchers and agency partners set out to develop a treatment foster care model for older youth based on Multi-dimensional Treatment Foster Care (MTFC). After matching youth by mental health condition and determining for whom randomization would be allowed, 14 youth were randomized to treatment as usual or a treatment foster home intervention. Stakeholders were interviewed qualitatively at multiple time points. Quantitative measures assessed mental health symptoms, days in locked facilities, employment and educational outcomes., Results: Development efforts led to substantial variations from the MTFC model and a new model, Treatment Foster Care for Older Youth was piloted. Feasibility monitoring suggested that it was difficult, but possible to recruit and randomize youth from and out of residential homes and that foster parents could be recruited to serve them. Qualitative data pointed to some qualified clinical successes. Stakeholders viewed two team roles - that of psychiatric nurse and skills coaches - very highly. However, results also suggested that foster parents and some staff did not tolerate the intervention well and struggled to address the emotion dysregulation issues of the young people they served. Quantitative data demonstrated that the intervention was not keeping youth out of locked facilities., Conclusions: The intervention needed further refinement prior to a broader trial. Intervention development work continued until components were developed to help address emotion regulation problems among fostered youth. Psychiatric nurses and skills coaches who work with youth in community settings hold promise as important supports for older youth with psychiatric needs.

Objective: To examine the feasibility and outcomes of video-based peer feedback through social networking to facilitate robotic surgical skill acquisition., Background: The acquisition of surgical skills may be challenging for novel techniques and/or those with prolonged learning curves., Methods: Randomized controlled trial involving 41 resident physicians performing the Tubes (Da Vinci Intuitive Surgical, Sunnyvale, CA) simulator exercise with versus without peer feedback of video-recorded performance through a social networking Web page. Data collected included simulator exercise score, time to completion, and comfort and satisfaction with robotic surgery simulation., Results: There were no baseline differences between the intervention group (n = 20) and controls (n = 21). The intervention group showed improvement in mean scores from session 1 to sessions 2 and 3 (60.7 vs 75.5, P < 0.001, and 60.7 vs 80.1, P < 0.001, respectively). The intervention group scored significantly higher than controls at sessions 2 and 3 (75.5 vs 59.6, P = 0.009, and 80.1 vs 65.9, P = 0.019, respectively). The mean time (seconds) to complete the task was shorter for the intervention group than for controls during sessions 2 and 3 (217.4 vs 279.0, P = 0.004, and 201.4 vs 261.9, P = 0.006, respectively). At the study conclusion, feedback subjects were more comfortable with robotic surgery than controls (90% vs 62%, P = 0.021) and expressed greater satisfaction with the learning experience (100% vs 67%, P = 0.014). Of the intervention subjects, 85% found that peer feedback was useful and 100% found it effective., Conclusions: Video-based peer feedback through social networking appears to be an effective paradigm for surgical education and accelerates the robotic surgery learning curve during simulation.

- Abstract
Objective: This study aimed to determine the effect of topical lidocaine on Penetration-Aspiration Scale (PAS) scores and patient comfort and tolerance of flexible endoscopic evaluation of swallowing (FEES) examinations in dysphagic patients., Methods: Adults with dysphagia referred for swallowing evaluation were recruited to participate in consecutive nonanesthetized and then anesthetized FEES examinations. Under endoscopic visualization, participants consumed 6 swallows consisting of graduated volumes of milk, pudding, and cracker in each condition and recorded their discomfort and tolerance in the 2 conditions. Penetration-Aspiration Scale scores were assigned in blinded fashion for each swallow., Results: Twenty-five adults participated in the study. Although there was no statistically significant effect of anesthesia on PAS scores (P=.065), the odds of a higher PAS score were 33% higher during anesthetized swallows. The anesthetized condition yielded significantly less discomfort and pain during the examination, significantly less pain and discomfort during insertion and removal of the endoscope, and significantly greater overall tolerance than the nonanesthetized condition., Conclusion: The use of topical lidocaine during FEES may impair swallowing ability in patients with dysphagia, but this result does not achieve statistical significance. Topical nasal anesthesia significantly reduces subjective pain and discomfort and improves tolerance during FEES., (© The Author(s) 2014.)

- Abstract
Objectives: To perform a population-based analysis to characterize the effect of prostate-specific antigen (PSA) testing on oncologic outcomes in men diagnosed with prostate cancer., Materials and Methods: We used the Surveillance, Epidemiology, and End Results-Medicare-linked data to identify 98,883 men diagnosed with prostate cancer from 1996 to 2007. We stratified frequency of PSA testing as none, 1 to 2, 3 to 5, and≥6 tests in the 5 years before prostate cancer diagnosis. We used propensity scoring methods to assess the effect of frequency of PSA testing on likelihood of (1) metastases at diagnosis and (2) overall mortality and prostate cancer-specific mortality., Results: In adjusted analyses, the likelihood of being diagnosed with metastatic prostate cancer decreased with greater frequency of PSA testing (none, 10.6; 1-2, 8.3; 3-5, 3.7; and≥6, 2.5 events per 100 person years, P<0.001). Additionally, greater frequency of PSA testing was associated with improved overall survival and prostate cancer-specific survival (P<0.001 for both)., Conclusions: Greater frequency of PSA testing in men 70 years of age or older in the 5 years before prostate cancer diagnosis is associated with lower likelihood of being diagnosed with metastatic prostate cancer and improved overall and prostate cancer-specific survival., (Copyright © 2014 Elsevier Inc.

- Abstract
Objective: To examine the impact of radical prostatectomy (RP) operative time on outcomes and cost, we performed a population-based assessment of operative time as a predictor of outcomes. Although operative time has been used as a metric to evaluate RP surgeon learning curves, the effect of RP operative times on outcomes remains understudied., Materials and Methods: We used US Surveillance, Epidemiology, and End Results-Medicare linked data to identify 7534 men aged≥66 years diagnosed with prostate cancer during 2003-2007 who underwent RP for localized prostate cancer through 2009. We categorized RP operative time into quartiles (short, intermediate, long, and very long) and used propensity score analyses to assess its impact on perioperative complications, mortality, length of hospitalization, readmissions, emergency room visits, and costs., Results: Quartiles ranged from 0 to 172 minutes for short, 173 to 214 minutes for intermediate, 215 to 268 minutes for long, and ≥269 minutes for very long RP operative times. After propensity score adjustment, longer operative time was associated with more surgery-related complications (short, 12.0%; intermediate, 12.3%; long, 14.4%; and very long, 22.8%; P<.001), longer median (interquartile range) length of stay in days (short, 2 [2-3]; intermediate, 2 [2-3]; long, 2 [1-3]; and very long, 2 [1-3]; P<.001), and higher median costs (short, $10,647; intermediate, $10,957; long, $11,405; and very long, $11,966; P<.001)., Conclusion: Longer RP operative time is associated with more complications, longer lengths of hospital stay, and higher costs. Increasing operative efficiency may reduce complications, length of stay, and health-care costs., (Copyright © 2014 Elsevier Inc. All rights reserved.)

- Abstract
Objectives: To determine factors that influence radical prostatectomy (RP) operative times. Operative time assessment is inherent to defining surgeon learning curves and evaluating quality of care., Subjects/patients and Methods: Population-based observational cohort study using USA Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data of men diagnosed with prostate cancer during 2003-2007 who underwent robot-assisted radical prostatectomy (RARP, 3458 men) and retropubic RP (RRP, 6993) through to 2009. We obtained median operative time using anaesthesia administrative data for RP and used median regression to assess the contribution of patient, surgeon, and hospital factors to operative times., Results: The median RARP operative time decreased from 315 to 247 min from 2003 to 2008-2009 (P < 0.001), while the median RRP operative time remained similar (195 vs 197 min, P = 0.90). In adjusted analysis, RARP vs RRP (parameter estimate [PE] 70.9; 95% confidence interval [CI] 58, 84; P < 0.001) and obesity (PE 15; 95% CI 7, 23; P < 0.001) were associated with longer operative times while higher surgeon volumes were associated with shorter operative times (P < 0.001). RPs performed by surgeons employed by group (parameter estimate [PE] -22.76; 95% CI -38, -7.49; P = 0.004) and non-government (PE -35.59; 95% CI -68.15, -3.03; P = 0.032) vs government facilities and non-profit vs government hospital ownership (PE -21.85; 95% CI -32.28, -11.42; P < 0.001) were associated with shorter operative times., Conclusions: During our study period, RARP operative times decreased by 68 min while RRP operative times remained stagnant. Higher surgeon volume was associated with shorter operative times, and selective referral or improved efficiency to the level of high-volume surgeons would net almost $15 million (USA dollars) in annual savings., (© 2013 The Authors.

- Abstract
Introduction: Late-onset hypogonadism may impair quality of life and contribute to metabolic and cardiovascular comorbidity in aging men. Testosterone replacement therapy is effective in treating hypogonadism. However, for the millions of men with a history of prostate cancer, exogenous testosterone has long been considered contraindicated, even though little data in such men are available. Clarification of this safety issue could allow treatment to be considered for a sizeable segment of the aging male population., Aim: The aim of this study is to examine population-based utilization and impact of testosterone replacement therapy in men with prostate cancer., Methods: Using linked Surveillance, Epidemiology, and End Results-Medicare data, we identified 149,354 men diagnosed with prostate cancer from 1992 to 2007. Of those, 1181 (0.79%) men received exogenous testosterone following their cancer diagnosis. We used propensity scoring analysis to examine the effect of testosterone replacement on the use of salvage hormone therapy and overall and prostate cancer-specific mortality., Main Outcome Measures: We assessed overall mortality, cancer-specific mortality, and the use of salvage hormone therapy., Results: Following prostate cancer diagnosis, testosterone replacement was directly related to income and educational status and inversely related to age (all P < 0.001). Men undergoing radical prostatectomy and men with well-differentiated tumors were more likely to receive testosterone (all P < 0.001). On adjusted analysis, testosterone replacement therapy was not associated with overall or cancer-specific mortality or with the use of salvage hormone therapy., Conclusions: In this population-based observational study of testosterone replacement therapy in men with a history of prostate cancer, treatment was not associated with increased overall or cancer-specific mortality. These findings suggest testosterone replacement therapy may be considered in men with a history of prostate cancer, but confirmatory prospective studies are needed., (© 2014 International Society for Sexual Medicine.)

- Abstract
Background: Atypia or follicular lesion of undetermined significance (AUS) is a cytologic category of thyroid aspirates with a wide range of reported malignancy. We aimed to determine whether specific cytologic features are associated with different rates of thyroid malignancy., Methods: All thyroid fine needle aspiration biopsies with AUS from 2010 to 2012 were reanalyzed. Cytologic features were correlated with final pathology. Cytopathologists were blinded to the original cytologic interpretation and final diagnosis., Results: Seventy-six patients had AUS; 39 (54%) underwent surgery with a malignancy rate of 18%. Specimens with moderate or large amount of thin colloid and absent or few nuclear inclusions had a >88% rate of benign disease. More than rare nuclear inclusions or grooves were associated with a higher rate of cancer (75% vs 9%, P = .005; 45% vs 7%, P = .003)., Conclusions: Patients with AUS and more than rare nuclear inclusions or grooves are at higher risk for cancer and should forego repeat fine needle aspiration biopsy and undergo thyroidectomy., (Copyright © 2014 Elsevier Inc.

- Abstract
Objective: Tracheal reconstruction using a stem cell-based engineered trachea has recently shown promise. Our goal is to achieve a single-stage stem cell-based tracheal replacement., Study Design: Prospective feasibility study., Setting: Wake Forest Institute of Regenerative Medicine., Subjects and Methods: Five healthy male beagles were implanted with a 2.5-cm segment of decellularized trachea. A sixth animal, planned for the control arm, died of anesthetic complications prior to tracheal implantation. The remaining 5 beagles were divided into 2 study arms: 4 had adipose-derived stem cells coating the lumen of the donor trachea, and a control animal had the trachea implanted cell free. The donor tracheas were obtained from previously sacrificed size-matched canines and decellularized. The adipose tissue was harvested from a recipient animal and the trachea prepared, seeded, and then implanted, all in one operation. Adipose stem cells were labeled fluorescently., Results: Five of 6 planned surgical procedures were completed successfully. All required sacrifice for airway distress at approximately 1 week postoperatively. All tracheal grafts were found to be malacic and compromised., Conclusion: In a canine model using a decellularized tracheal scaffold and adipose stem cells, the postoperative inflammatory response and evidence of rejection was minimal. However, all scaffolds exhibited breakdown, compromising the animals' airways, necessitating euthanasia earlier than planned. For future study, a similar animal model using a single-stage approach with a more robust scaffold may allow for greater survival and stem cell differentiation.

- Abstract
Older youth served in the foster care system have elevated rates of mental health disorders and are high users of mental health services, yet concerns have been raised about the quality of this care. This paper describes the details of a psychiatric nurse's work within a multidisciplinary team to address gaps in care for older youth with psychiatric disorders. We describe the process, outcomes, and lessons learned in developing and piloting a psychiatric nurse intervention for older youth in the foster care system as part of a multidimensional treatment foster care program. Our experiences support further work to develop a role for nursing to improve the quality of mental health treatment in foster care., (© 2013.)

- Abstract
Introduction: Due to the increasing number of clinical trials conducted globally, there is a need for quality continuing education for health professionals in clinical research manager (CRM) roles. This article describes the development, implementation, and evaluation of a distance-based continuing education program for CRMs working outside the United States., Methods: A total of 692 applications were received from CRMs in 50 countries. Of these, 166 were admitted to the program in two cohorts. The program, taught online and in English, included 4 required and 1 optional course. Course materials were also provided as hard copies and on CDs. A pretest/posttest design was used to evaluate the outcome of the program in terms of changes in knowledge, participants' capacity-building activities at their research sites; and participant and supervisor perceptions of program impact., Results: Participants demonstrated significant improvements in knowledge about clinical research, rated course content and teaching strategies positively, and identified the opportunity for interactions with international peers as a major program strength. Challenges for participants were limited time to complete assignments and erratic Internet access. Participants offered capacity-building programs to 5061 individuals at their research sites. Supervisors indicated that they would recommend the program and perceived the program improved CRM effectiveness and site research capacity., Discussion: Results suggest that this type of continuing education program addresses a growing need for education of CRMs working in countries that have previously had limited involvement with global clinical trials., (Copyright © 2013 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on CME, Association for Hospital Medical Education.)

- Abstract
Youth served in the foster care system have higher rates of pregnancy than general population youth; yet we have little information about risk and protective factors to target in order to prevent early pregnancy in this population. We assessed early pregnancy risk and protective factors known for general population adolescents for their relevance to youth in the foster care system. Using data from a longitudinal study of 325 older youth from the foster care system, we examined bivariate and multivariate relationships between these factors and pregnancy between age 17 and 19 using logistic regression. Models examined risk for early parenting separately by gender. The pregnancy rate increased by 300% between ages 17 and 19. At 19, 55% of females had been pregnant, while 23% of males had fathered a child. Although this study assessed multiple known factors, few were significant for this high risk group. Females who were not sexually active at age 17 were less likely to become pregnant, but those who reported using birth control were as likely to become pregnant as those who did not. Also, females with a history of arrest were more likely to have a pregnancy between 17 and 19. Males who left the foster care system before their 19
th birthday were more likely to make someone pregnant. Youth from the foster care system are at exceptional risk of early pregnancy, no matter their maltreatment history, religiosity, school connectedness, or academic achievement, particularly in the years between 17 and 19. This high risk group needs pregnancy prevention interventions and access to effective birth control.- Published

- Abstract
Objectives: This article synthesizes discussion of collaborative research results, interventions and policy engagement for St Lawrence Island (SLI), Alaska, during the years 2000-2012., Methods: As part of on-going community-based participatory research (CBPR) studies on SLI, 5 discrete exposure-assessment projects were conducted: (a) a biomonitoring study of human blood serum; (b-d) 3 investigations of levels of contaminants in environmental media at an abandoned military site at Northeast Cape--using sediment cores and plants, semi-permeable membrane devices and blackfish, respectively; and (e) a study of traditional foods., Results: Blood serum in residents of SLI showed elevated levels of polychlorinated biphenyls (PCBs) with higher levels among those exposed to the military site at Northeast Cape, an important traditional subsistence-use area. Environmental studies at the military site demonstrated that the site is a continuing source of PCBs to a major watershed, and that clean-up operations at the military site generated PCB-contaminated dust on plants in the region. Important traditional foods eaten by the people of SLI showed elevated concentrations of PCBs, which are primarily derived from the long-range transport of persistent pollutants that are transported by atmospheric and marine currents from more southerly latitudes to the north., Interventions: An important task for all CBPR projects is to conduct intervention strategies as needed in response to research results. Because of the findings of the CBPR projects on SLI, the CBPR team and the people of the Island are actively engaging in interventions to ensure cleanup of the formerly used military sites; reform chemicals policy on a national level; and eliminate persistent pollutants internationally. The goal is to make the Island and other northern/Arctic communities safe for themselves and future generations., Conclusions: As part of the CBPR projects conducted from 2000 to 2012, a series of exposure assessments demonstrate that the leaders of SLI have reason to be concerned about the health of people due to the presence of carcinogenic chemicals as measured in biomonitoring and environmental samples and important traditional foods.

- Abstract
Objectives/hypothesis: To assess the effects of a typical otolaryngologic dose of 1 mL of 4% lidocaine on penetration aspiration scale scores and participant discomfort during flexible endoscopic evaluation of swallowing., Study Design: A prospective pilot study., Methods: Twenty healthy participants consumed 12 swallows consisting of graduated volumes of milk, water, pudding, and cracker in anesthetized and nonanesthetized conditions. Each participant was randomly selected to begin with the anesthetized or nonanesthetized condition. Each participant returned within 7 days to repeat the study in the other condition. Digital recordings of their evaluations were scored via the penetration-aspiration scale in a blinded fashion. Participants recorded their discomfort and tolerance of each flexible endoscopic evaluation of swallowing., Results: The anesthetized condition yielded significantly worse swallowing function (P = .001) than the nonanesthetized condition. The nonanesthetized condition yielded greater discomfort and pain during the procedure (P = .006, .018), greater pain during insertion and removal of the endoscope (P = .002, .003) and less overall tolerance (P = .016) than the anesthetized condition., Conclusions: A typical otolaryngologic anesthetic dose of 1 mL of 4% lidocaine during flexible endoscopic evaluation of swallowing predisposed healthy young adults to higher penetration aspiration scale scores (less safe swallowing) than the nonanesthetized condition; however, the anesthetic reduced discomfort and provided better overall tolerance. Future studies need to evaluate the effects of lower doses of lidocaine (0.2 and 0.5 mL) on swallowing function and comfort., (Copyright © 2012 The American Laryngological, Rhinological and Otological Society, Inc.)

- Abstract
Following Walsh's advances in pelvic anatomy and surgical technique to minimize intraoperative peri-prostatic trauma more than 30 years ago, open retropubic radical prostatectomy (RRP) evolved to become the gold standard treatment of localized prostate cancer, with excellent long-term survival outcomes [1•]. However, RRP is performed with great heterogeneity, even among high volume surgeons, and subtle differences in surgical technique result in clinically significant differences in recovery of urinary and sexual function. Since the initial description of robotic-assisted radical prostatectomy (RARP) in 2000 [2], and U.S. Food and Drug Administration approval shortly thereafter, RARP has been rapidly adopted and has overtaken RRP as the most popular surgical approach in the management of prostate cancer in the United States [3]. However, the surgical management of prostate cancer remains controversial. This is confounded by the idolatry of new technologies and aggressive marketing versus conservatism in embracing tradition. Herein, we review the literature to compare RRP to RARP in terms of perioperative, oncologic, and quality-of-life outcomes as well as healthcare costs. This is a particularly relevant, given the absence of randomized trials and long-term (more than 10-year) follow-up for RARP biochemical recurrence-free survival.

- Abstract
Prostate cancer is the second leading cause of cancer death among men in the USA. Use of robot-assisted radical prostatectomy (RARP) for the management of localized prostate cancer has increased dramatically in recent years. This review focuses on comparing quality of life following RARP versus retropubic radical prostatectomy. RARP is associated with improved perioperative outcomes, such as reduced blood loss and fewer transfusions. In addition, cancer control after RARP versus retropubic radical prostatectomy is equivalent, with similar incidences of positive surgical margins and comparable early oncological outcomes. RARP appears to provide advantages in recovery of continence, potency and quality of life compared with retropubic radical prostatectomy; however, methodological limitations exist in current literature.
