Background: Women who use drugs (WWUD) have low rates of contraceptive use and high rates of unintended pregnancy. Drug use is common among women in rural U.S. communities, with limited data on how they utilize reproductive, substance use disorder (SUD), and healthcare services., Objective: We determined contraceptive use prevalence among WWUD in rural communities then compared estimates to women from similar rural areas. We investigated characteristics of those using contraceptives, and associations between contraceptive use and SUD treatment, healthcare utilization, and substance use., Design: Rural Opioids Initiative (ROI) - cross-sectional survey using respondent-driven sampling (RDS) involving eight rural U.S. regions (January 2018-March 2020); National Survey on Family Growth (NSFG) - nationally-representative U.S. household reproductive health survey (2017-2019)., Participants: Women aged 18-49 with prior 30-day non-prescribed opioid and/or non-opioid injection drug use; fecundity determined by self-reported survey responses., Main Measures: Unweighted and RDS-weighted prevalence estimates of medical/procedural contraceptive use; chi-squared tests and multi-level linear regressions to test associations., Key Results: Of 855 women in the ROI, 36.8% (95% CI 33.7-40.1, unweighted) and 38.6% (95% CI 30.7-47.2, weighted) reported contraceptive use, compared to 66% of rural women in the NSFG sample. Among the ROI women, 27% had received prior 30-day SUD treatment via outpatient counseling or inpatient program and these women had increased odds of contraceptive use (aOR 1.50 [95% CI 1.08-2.06]). There was a positive association between contraception use and recent medications for opioid use disorder (aOR 1.34 [95% CI 0.95-1.88]) and prior 6-month primary care utilization (aOR 1.32 [95% CI 0.96-1.82]) that did not meet the threshold for statistical significance., Conclusion: WWUD in rural areas reported low contraceptive use; those who recently received SUD treatment had greater odds of contraceptive use. Improvements are needed in expanding reproductive and preventive health within SUD treatment and primary care services in rural communities., (© 2022. The Author(s).)

Despite advances in identifying malnutrition at hospital admission, decline in nutritional status of well-nourished patients can be overlooked. The aim of this systematic review was to investigate the incidence of hospital-acquired malnutrition (HAM), diagnostic criteria and health-related outcomes. PubMed, CINAHL, Embase and Cochrane Library were searched up to July 2021. Studies were included if changes in nutritional status was assessed with a validated nutrition assessment tool in acute and subacute adult (≥18 yrs) hospitalised patients. A random-effects method was used to pool the incidence proportion of HAM in prospective studies. The certainty of evidence was appraised using the Grading of Recommendation Assessment, Development and Evaluation system. We identified 12 observational cohort studies (10 prospective and 2 retrospective), involving 35,324 participants from acute (9 studies) and subacute settings (3 studies). Retrospective studies reported a lower incidence of HAM (<1.4%) than prospective studies (acute: 9-38%; subacute: 0-7%). The pooled incidence of HAM in acute care was 25.9% (95% confidence interval (CI): 17.3-34.6). Diagnostic criteria varied, with use of different nutrition assessment tools and timeframes for assessment (retrospective studies: >14 days; prospective studies: ≥7 days). Nutritional decline is probably associated with longer length of stay and higher 6-month readmission (moderate certainty of evidence) and may be association with higher complications and infections (low certainty of evidence). The higher incidence of HAM in the acute setting, where nutritional assessments are conducted prospectively, highlights the need for consensus regarding diagnostic criteria and further studies to understand the impact of HAM., (© 2022.

The aim of this study was to assess the chemical/mechanical properties of ion-releasing dental sealants containing strontium-bioactive glass nanoparticles (Sr-BGNPs) and monocalcium phosphate monohydrate (MCPM). Two experimental sealants, TS1 (10 wt% Sr-BGNPs and 2 wt% MCPM) and TS2 (5 wt% Sr-BGNPs and 4 wt% MCPM), were prepared. Commercial controls were ClinproXT (CP) and BeautiSealant (BT). The monomer conversion (DC) was tested using ATR−FTIR (n = 5). The biaxial flexural strength (BFS) and modulus (BFM) were determined (n = 5) following 24 h and 7 days of immersion in water. The Vickers surface microhardness (SH) after 1 day in acetic acid (conc) versus water was tested (n = 5). The bulk and surface calcium phosphate precipitation in simulated body fluid was examined under SEM-EDX. The ion release at 4 weeks was analyzed using ICP-MS (n = 5). The DC after 40 s of light exposure of TS1 (43%) and TS2 (46%) was significantly lower than that of CP (58%) and BT (61%) (p < 0.05). The average BFS of TS1 (103 MPa), TS2 (123 MPa), and BT (94 MPa) were lower than that of CP (173 MPa). The average BFM and SH of TS1 (2.2 GPa, 19 VHN) and TS2 (2.0 GPa, 16 VHN) were higher than that of CP (1.6 GPa, 11 VHN) and BT (1.3 GPa, 12 VHN). TS1 showed higher Ca, P, and Sr release than TS2. Bulk calcium phosphate precipitation was detected on TS1 and TS2 suggesting some ion exchange. In conclusion, the DC of experimental sealants was lower than that of commercial materials, but their mechanical properties were within the acceptable ranges. The released ions may support remineralizing actions.

Objectives: To identify and examine the reported effectiveness of education programs for health professionals on frailty., Methods: A systematic review was conducted of articles published up to June 2021, examining the evaluation of frailty training or education programs targeting health professionals/students. The participant demographics, program content and structure, effectiveness assessment methodology and outcomes, as well as participant feedback, were recorded with narrative synthesis of results., Results: There were nine programs that have evaluated training of health professionals in frailty. These programs varied with respect to intensity, duration, and delivery modality, and targeted a range of health professionals and students. The programs were well-received and found to be effective in increasing frailty knowledge and self-perceived competence in frailty assessment. Common features of successful programs included having multidisciplinary participants, delivering a clinically tailored program and using flexible teaching modalities. Of note, many programs assessed self-perceived efficacy rather than objective changes in patient outcomes., Conclusions: Despite increasing attention on frailty in clinical practice, this systematic review found that there continues to be limited reporting of frailty training programs., (© 2022 The Authors.

Some would argue that kids aren't just little adults, but what about their sternums? We are reviewing a manuscript by Horriat, McCandless, and colleagues in the Journal of Cardiac Surgery describing their experience with managing sternal wound infections (SWI) after congenital heart surgery. They report encouraging results in 14 patients who required plastic surgery consultation to manage their sternal wounds. The nature of congenital cardiac abnormalities and the necessary steps to repair them leads to physiologic derangements predisposing patients to SWI. Rates of SWI vary and have been reported at 1.53% in this population. There is little guidance on how the management of the congenital cardiac surgery patient should differ from the adult patient., (© 2022 Wiley Periodicals LLC.)

Introduction: Opioid-involved overdose deaths continue to surge in many communities, despite numerous evidence-based practices (EBPs) that exist to prevent them. The HEALing Communities Study (HCS) was launched to develop and test an intervention (ie, Communities That HEAL (CTH)) that supports communities in expanding uptake of EBPs to reduce opioid-involved overdose deaths. This paper describes a protocol for a process foundational to the CTH intervention through which community coalitions select strategies to implement EBPs locally., Methods and Analysis: The CTH is being implemented in 67 communities (randomised to receive the intervention) in four states in partnership with coalitions (one per community). Coalitions must select at least five strategies, including one to implement each of the following EBPs: (a) overdose education and naloxone distribution; expanded (b) access to medications for opioid use disorder (MOUD), (c) linkage to MOUD, (d) retention in MOUD and (e) safer opioid prescribing/dispensing. Facilitated by decision aid tools, the community action planning process includes (1) data-driven goal setting, (2) discussion and prioritisation of EBP strategies, (3) selection of EBP strategies and (4) identification of next steps. Following review of epidemiologic data and information on existing local services, coalitions set goals and discuss, score and/or rank EBP strategies based on feasibility, appropriateness within the community context and potential impact on reducing opioid-involved overdose deaths with a focus on three key sectors (healthcare, behavioural health and criminal justice) and high-risk/vulnerable populations. Coalitions then select EBP strategies through consensus or majority vote and, subsequently, suggest or choose agencies with which to partner for implementation., Ethics and Dissemination: The HCS protocol was approved by a central Institutional Review Board (Advarra). Results of the action planning process will be disseminated in academic conferences and peer-reviewed journals, online and print media, and in meetings with community stakeholders., Trial Registration Number: NCT04111939., Competing Interests: Competing interests: Competing interest disclosures include the following: LSM is a consultant for the Boston Public Health Commission, Action for Boston Area development and the Young Foundation, SLW has served as a scientific advisor to Opiant Pharmaceuticals, Titan Pharmaceuticals, Astra Zeneca, Cerevel, Arbor Pharmaceuticals, Brainsway, Summit Biosciences, Trevi and Camurus.

Attitudes toward wildlife can have direct implications on children's interest in conservation behaviors. Animal programs are an example of interactive, educational experiences that have the potential to change attitudes by providing individuals the opportunity to get close to animal ambassadors and participate in engaging conversations about them. We conducted an animal program assessment with summer camps at the Ohio Wildlife Center to quantify changes in children's affiliation with local wildlife and their willingness to live near local wildlife. Campers showed an overall increase in affiliation and willingness scores from before to after an animal program, although with a small effect size. Overall willingness scores were lower than affiliation scores, but there was a significantly larger increase in willingness following the program. We found a strong correlation between affiliation and willingness scores. Overall, the study found that these animal programs positively influenced children's attitudes toward local wildlife and increased their willingness to live near them, suggesting animal programming could be used to decrease human-wildlife conflict. Visually seeing animals in the programs improved attitude scores, even for those not seen in this study, which suggests that program animals can act as an ambassador for other species. This opens the potential for utilizing animal ambassadors as powerful tools in conservation education about threatened and endangered species., (© 2022 The Authors.

Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA/VSD/MAPCA) represents an anatomically diverse and technically demanding spectrum of congenital disease. Here, we review a manuscript by Onalan et al. in the Journal of Cardiac Surgery detailing a retrospective, single-center cohort study of patients undergoing unifocalization for PA/VSD/MAPCA via either a pulmonary artery patch augmentation or pericardial roll technique. While they report statistically equivalent outcomes using both techniques, longer follow-up and increased sample size are necessary to determine efficacy and safety., (© 2022 Wiley Periodicals LLC.)

Background: Previous research has revealed under-reporting of personal network members (i.e., alters) in studies involving people who use drugs (PWUD). This analysis (1) characterizes relationships that were more likely to be omitted but later recalled with prompting and (2) identifies network structural characteristics most impacted by these omissions among a sample of PWUD in rural Appalachian Kentucky, an epicenter of the opioid epidemic., Methods: Data were collected through longitudinal assessments as part of the Social Networks Among Appalachian People (SNAP) study (2008-2017). Study participants completed interviewer-administered questionnaires that collected social network data via free-listing at baseline and six-month intervals. At visit 5, after free-listing, interviewers prompted participants with the names of previously reported alters. We used modified Poisson regression with generalized estimating equations to identify individual- and relationship-level characteristics associated with an alter being reported only after prompting. We examined the impact of including vs. excluding relationships reported after prompting on local and global sociometric network measures (i.e., betweenness centrality, bridging, density, mean degree, transitivity, cliques, and 2-cores)., Results: Relationships reported only after prompting were more likely to be immediate family (Adjusted Prevalence Ratio [APR]:1.29; 95% Confidence Interval [CI]: 1.03-1.63) and less likely to involve sex (APR:0.54; 95% CI: 0.43-0.67). Considerable differences were observed for participant positional rankings of betweenness centrality and bridging, and differences in network density and average degree pre- and post-prompting were statistically significant., Conclusion: Longitudinal network studies that aim to assess transmission dynamics, information diffusion, or peer influence should consider the effects of omitted relationships., (Copyright © 2022 Elsevier B.V.

This study's aim was to assess whether the Renewal MI composite can self-etch enamel, seal sound cavities, and stabilize demineralized dentine. Etching was assessed using scanning electron microscopy (SEM). Cavity sealing was quantified using the ISO-11405 dye microleakage test. Demineralized dentine stabilization was evaluated by visualizing resin tag formation, enzyme activity and mineral precipitation at the adhesion interface. Renewal MI provided a mild etching of sound enamel in comparison with 37% phosphoric acid. It provided a comparable seal of sound cavities to Z250/Scotchbond Universal adhesive and a superior seal to Activa, Fuji IX and Fuji II LC. With demineralized dentine, Renewal MI formed 300-400 µm resin tags covering 63% of the adhesion interface compared with 55 and 39% for Z250/Scotchbond and Activa. Fuji IX and Fuji II LC formed no resin tags. A higher tag percentage correlated with lower surface enzyme activity. Unlike Activa and Fuji II LC, Renewal MI promoted mineral precipitation from simulated body fluid, occluding adjacent dentinal tubules within 6 months. These novel etching and sealing properties may facilitate Renewal MI's application in minimally invasive dentistry.

Importance: Overdoses continue to increase in the US, but the contribution of methamphetamine use is understudied in rural communities., Objective: To estimate the prevalence of methamphetamine use and its correlates among people who use drugs (PWUD) in rural US communities and to determine whether methamphetamine use is associated with increased nonfatal overdoses., Design, Setting, and Participants: From January 2018 through March 2020, the National Rural Opioid Initiative conducted cross-sectional surveys of PWUD in rural communities in 10 states (Illinois, Kentucky, New Hampshire, Massachusetts, North Carolina, Ohio, Oregon, Vermont, West Virginia, and Wisconsin). Participants included rural PWUD who reported any past-30-day injection drug use or noninjection opioid use to get high. A modified chain-referral sampling strategy identified seeds who referred others using drugs. Data analysis was performed from May 2021 to January 2022., Exposures: Use of methamphetamine alone, opioids alone, or both., Main Outcomes and Measures: Unweighted and weighted prevalence of methamphetamine use, any past-180-day nonfatal overdose, and number of lifetime nonfatal overdoses., Results: Among the 3048 participants, 1737 (57%) were male, 2576 (85%) were White, and 225 (7.4%) were American Indian; the mean (SD) age was 36 (10) years. Most participants (1878 of 2970 participants with any opioid or methamphetamine use [63%]) reported co-use of methamphetamine and opioids, followed by opioids alone (702 participants [24%]), and methamphetamine alone (390 participants [13%]). The estimated unweighted prevalence of methamphetamine use was 80% (95% CI, 64%-90%), and the estimated weighted prevalence was 79% (95% CI, 57%-91%). Nonfatal overdose was greatest in people using both methamphetamine and opioids (395 of 2854 participants with nonmissing overdose data [22%]) vs opioids alone (99 participants [14%]) or methamphetamine alone (23 participants [6%]). Co-use of methamphetamine and opioids was associated with greater nonfatal overdose compared with opioid use alone (adjusted odds ratio, 1.45; 95% CI, 1.08-1.94; P = .01) and methamphetamine use alone (adjusted odds ratio, 3.26; 95% CI, 2.06-5.14; P < .001). Those with co-use had a mean (SD) of 2.4 (4.2) (median [IQR], 1 [0-3]) lifetime overdoses compared with 1.7 (3.5) (median [IQR], 0 [0-2]) among those using opioids alone (adjusted rate ratio, 1.20; 95% CI, 1.01-1.43; P = .04), and 1.1 (2.9) (median [IQR], 0 [0-1]) among those using methamphetamine alone (adjusted rate ratio, 1.81; 95% CI, 1.45-2.27; P < .001). Participants with co-use most often reported having tried and failed to access substance use treatment: 827 participants (44%) for both, 117 participants (30%) for methamphetamine alone, and 252 participants (36%) for opioids alone (χ22 = 33.8; P < .001). Only 66 participants (17%) using methamphetamine alone had naloxone., Conclusions and Relevance: These findings suggest that harm reduction and substance use disorder treatment interventions must address both methamphetamine and opioids to decrease overdose in rural communities.

Objective: To characterize and address the opioid crisis disproportionately impacting rural U.S. regions., Methods: The Rural Opioid Initiative (ROI) is a two-phase project to collect and harmonize quantitative and qualitative data and develop tailored interventions to address rural opioid use. The baseline quantitative survey data from people who use drugs (PWUD) characterizes the current opioid epidemic (2018-2020) in eight geographically diverse regions., Results: Among 3,084 PWUD, 92% reported ever injecting drugs, 86% reported using opioids (most often heroin) and 74% reported using methamphetamine to get high in the past 30 days; 53% experienced homelessness in the prior 6 months; and 49% had ever overdosed. Syringe service program use varied by region and 53% had ever received an overdose kit or naloxone prescription. Less than half (48%) ever received medication for opioid use disorder (MOUD)., Conclusions: The ROI combines data across eight rural regions to better understand drug use including drivers and potential interventions in rural areas with limited resources. Baseline ROI data demonstrate extensive overlap between opioid and methamphetamine use, high homelessness rates, inadequate access to MOUD, and other unmet needs among PWUD in the rural U.S. By combining data across studies, the ROI provides much greater statistical power to address research questions and better understand the syndemic of infectious diseases and drug use in rural settings including unmet treatment needs., (© 2022.

Background: Despite experiencing the second-highest rate of HIV incidence in the United States, pre-exposure prophylaxis (PrEP) use remains low among Black women due, in part, to a lack of patients' awareness and providers' knowledge., Objective: Our goal was to design animated educational tools informed by patients and women's health providers to address these barriers, specifically for women at risk for HIV., Methods: Two animation storyboards about PrEP for women were created by academic stakeholders (eg, HIV clinical experts, educators, and HIV peer counselors), one for patients and one for providers. Four focus groups with community members from Baltimore, Maryland and four with women's health providers (eg, obstetrician/gynecologists, midwives, nurse practitioners, and peer counselors) at an academic center were conducted to discuss the storyboards. Transcripts were analyzed using conventional content analysis, and themes were incorporated into the final versions of the animations., Results: Academic stakeholders and 30 focus group participants (n=16 female community members and n=14 women's health providers) described important themes regarding PrEP. The themes most commonly discussed about the patient animation were understandability of side effects, HIV risk factors, messaging, PrEP access, and use confidence. Provider animation themes were indications for PrEP, side effects, and prescribing confidence., Conclusions: We created two PrEP animations focused on women. Stakeholder feedback highlighted the importance of ensuring the understandability and applicability of PrEP educational materials while including necessary information to facilitate use or prescribing confidence. Both community members and women's health providers reported greater use confidence after viewing the animations., (©Anna Marie Young, Timothee Fruhauf, Obianuju Okonkwo, Erin Gingher, Jenell Coleman.

Gender based violence (GBV) is a significant public health concern for women globally, including countries such as India. The researchers investigated factors related to GBV and GBV-related homicides perpetrated by both husbands and in-laws using a qualitative approach. Data were collected from 27 women in India. Analysis revealed factors at the societal/cultural (e.g. dowry), community (e.g. inadequate resources), relationship (e.g. in-laws abuse) and individual (e.g. internalized powerlessness) levels. Findings highlight the need for culturally appropriate risk assessment and safety planning procedures, as well as policies and programs across different ecological levels to reduce risk for GBV and GBV-related homicides.

Introduction: Rural communities bear a disproportionate share of the opioid and methamphetamine use disorder epidemics. Yet, rural people who use drugs (PWUD) are rarely included in trials testing new drug use prevention and treatment strategies. Numerous barriers impede rural PWUD trial engagement and advancing research methods to better retain rural PWUD in clinical trials is needed. This paper describes the Peer-based Retention Of people who Use Drugs in Rural Research (PROUD-R 2 ) study protocol to test the effectiveness of a peer-driven intervention to improve study retention among rural PWUD., Methods and Analysis: The PROUD-R 2 study is being implemented in 21 rural counties in three states (Kentucky, Ohio and Oregon). People who are 18 years or older, reside in the study area and either used opioids or injected any drug to get high in the past 30 days are eligible for study inclusion. Participants are allocated in a 1:1 ratio to two arms, stratified by site to assure balance at each geographical location. The trial compares the effectiveness of two retention strategies. Participants randomised to the control arm provide detailed contact information and receive standard retention outreach by study staff (ie, contacts for locator information updates, appointment reminders). Participants randomised to the intervention arm are asked to recruit a 'study buddy' in addition to receiving standard retention outreach. Study buddies are invited to participate in a video training and instructed to remind their intervention participant of follow-up appointments and encourage retention. Assessments are completed by intervention, control and study buddy participants at 6 and 12 months after enrolment., Ethics and Dissemination: The protocol was approved by a central Institutional Review Board (University of Utah). Results of the study will be disseminated in academic conferences and peer-reviewed journals, online and print media, and in meetings with community stakeholders., Trial Registration Number: NCT03885024., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: Men who have sex with men (MSM) residing outside of large urban areas are underrepresented in research on online partner seeking and sexual behaviors related to transmission of HIV., Objective: We aimed to determine associations between the use of the internet or social networking apps (online tools) to meet partners for sex, dating, or for both purposes (online partner seeking) and sexual behaviors among MSM residing in small and midsized towns in Kentucky, United States., Methods: Using peer-referral sampling and online self-administered questionnaires, data were collected from 252 men, aged 18 to 34 years, who had recently (past 6 months) engaged in anal sex with another man and resided in Central Kentucky. Using multivariable logistic regression models, we assessed associations of online partner seeking and HIV-related sexual behaviors., Results: Most (181/252, 71.8%) of the participants reported using online tools for partner seeking. Of these 181 respondents, 166 (91.7%) had used online tools to meet partners for sex (n=45, 27.1% for sex only; and n=121, 72.9% for sex and dating) and 136 (75.1%) had used online tools to meet partners for dating (n=15, 11% for dating only; and n=121, 89% for sex and dating). Adjusted analyses revealed that MSM who had engaged in condomless insertive and receptive anal intercourse were less likely to report online partner seeking (adjusted odds ratio [aOR] 0.22, 95% CI 0.07-0.68; P=.009 and aOR 0.25, 95% CI 0.10-0.66; P=.005, respectively). Increased number of insertive and receptive anal sex partners and substance use before or during sex were associated with higher odds of online partner seeking (aOR 1.31, 95% CI 1.11-1.55; P=.001; aOR 1.20, 95% CI 1.05-1.39; P=.008; and aOR 2.50, 95% CI 1.41-4.44; P=.002, respectively)., Conclusions: Among MSM who reside outside of large urban areas and practice online partner seeking, HIV risk-reduction interventions should address safer sex practices, including the risks for HIV transmission associated with alcohol or drug use before or during sex. MSM who do not practice online partner seeking are in need of continued outreach to reduce condomless anal sex., (©Vira Pravosud, April M Ballard, Ian W Holloway, April M Young.

What is the most optimal way to palliate univentricular physiology? We are reviewing a manuscript by Şimşek and colleagues in the Journal of Cardiac Surgery-describing their experience with the intraextracardiac Fontan procedure (IECF). They report encouraging early results in 17 patients who underwent the procedure between 2014 and 2021 and clearly describe their operative technique and variant anatomy they encountered. There are now at least four generations of Fontan procedures, each attempting to palliate while maintaining appropriate hemodynamics as long as possible. IECF provides a good option for cavopulmonary bypass as it avoids pitfalls of prior generations. It may be even more favorable in situations with additional anatomic complexity. We look forward to seeing the long-term outcomes of the IECF., (© 2022 Wiley Periodicals LLC.)

Extracardiac conduit-total cavopulmonary connection (EC-TCPC) represents the latest evolution in Fontan palliation for single ventricle physiology. Here, we review a manuscript by Pan et al. in the Journal of Cardiac Surgery detailing a retrospective, single-center cohort study of patients with and without heterotaxy syndrome undergoing EC-TCPC. Although lacking a comparison to other techniques for single ventricle palliation, this approach appears to offer excellent outcomes for this complex patient cohort., (© 2022 Wiley Periodicals LLC.)

Previous studies have demonstrated a correlation between longevity and brain size in a variety of taxa. Little research has been devoted to understanding this link in parrots; yet parrots are well-known for both their exceptionally long lives and cognitive complexity. We employed a large-scale comparative analysis that investigated the influence of brain size and life-history variables on longevity in parrots. Specifically, we addressed two hypotheses for evolutionary drivers of longevity: the cognitive buffer hypothesis , which proposes that increased cognitive abilities enable longer lifespans, and the expensive brain hypothesis , which holds that increases in lifespan are caused by prolonged developmental time of, and increased parental investment in, large-brained offspring . We estimated life expectancy from detailed zoo records for 133 818 individuals across 244 parrot species. Using a principled Bayesian approach that addresses data uncertainty and imputation of missing values, we found a consistent correlation between relative brain size and life expectancy in parrots. This correlation was best explained by a direct effect of relative brain size. Notably, we found no effects of developmental time, clutch size or age at first reproduction. Our results suggest that selection for enhanced cognitive abilities in parrots has in turn promoted longer lifespans.

Objectives: To develop a minimum dataset to be routinely collected across a heterogenous population within a subacute rehabilitation service to guide best care and outcomes for patients, and value for the health service., Design: Three-round e-Delphi exercise, followed by consensus meetings., Setting: Multicentre study in Brisbane, Australia., Participants: Rehabilitation decision-makers, researchers and clinicians were invited to participate in the e-Delphi exercise. A multidisciplinary project steering committee (rehabilitation decision makers, researchers, clinicians and consumers) participated in consensus meetings., Methods: In round 1 of the e-Delphi, participants responded to an open-ended question, generating data and outcomes that should be routinely collected in rehabilitation. In rounds 2 and 3, participants rated the importance of collecting each item on a nine-point scale. Consensus was defined a priori, as items rated as 'essential' by at least 70%, and of 'limited importance' by less than 15%, of respondents. Consensus meetings were held to further refine and define the dataset for implementation., Results: In total, 38 participants completed round 1 of the e-Delphi. Qualitative content analysis of their responses generated 1072 codes, which were condensed into 39 categories and 209 subcategories. Following two rounds of rating (round 2: n=32 participants; round 3: n=28 participants), consensus was reached for 124 items. Four consensus meetings (n=14 participants) resulted in the final dataset which included 42 items across six domains: (1) patient demographics, (2) premorbid health and psychosocial information, (3) admission information, (4) service delivery and interventions, (5) outcomes and (6) caregiver information and outcomes., Conclusions: We identified 42 items that reflect the values and experiences of rehabilitation stakeholders. Items unique to this dataset include caregiver information and outcomes, and detailed service delivery and intervention data. Future research will establish the feasibility of collection in practice., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Bladder cancer (BC) is classified as a high-risk tumour type for venous thromboembolism (VTE). VTE presents an extra challenge in the management of patients with cancer, given the increase in morbidity and mortality on having both conditions. To summarise the contemporary evidence on the VTE rate in patients with BC according to the stage, type of anti-cancer treatment and highlight VTE rate in the UK and other countries. A systematic review was carried out, and an electronic search for publications between January 2000 and November 2021 was done. Studies recording VTE in BC patients were included, whilst paediatric patients, case reports, studies reporting on a mix of arterial and venous thrombosis, studies reporting DVT or PE only and recorded hospitalised VTE only were excluded. The rate of VTE, country of origin, risk factors and thromboprophylaxis duration for VTE in BC patients were identified. A total of 38 papers met the search criteria. All publications were original research papers (cohort studies). The overall VTE rate in patients with BC was estimated at 1.9% to 4.7%. For those patients undergoing cystectomy, the VTE rate ranged from 3% to 17.6%; however, the VTE rate in the metastatic stage of BC patients ranged from 3.1% to 5.1%. The rates of VTE in BC patients are high, further increased by interventions such as surgery and chemotherapy. Thromboprophylaxis measures should be optimised. This review highlighted the fact that the VTE rate in BC varies between studies due to the heterogeneity of risk factors reported., Competing Interests: The authors have declared financial relationships, which are detailed in the next section., (Copyright © 2022, Abdullah et al.)

How do manufacturer estimates of valve performance match up to reality and stress testing? We are reviewing a manuscript by Porterie et al. in the Journal of Cardiac Surgery detailing a single-center, assessment of Avalus™ bioprosthetic valve hemodynamics during stress echocardiography. At maximal stress, they found that indexed effective orifice area had better alignment with manufacturer estimates than measurements at rest. In addition, they found a significant difference between EOA and flow rates at rest versus maximal exertion and quantified it as the "opening reserve." Patients without patient prosthetic mismatch had much higher opening reserves. This interesting study helps us to understand how estimates align with reality and draws attention to the concept of the opening reserve. Could differences in opening flow impact the durability or longevity of prosthetics?, (© 2022 Wiley Periodicals LLC.)

The advent of transcatheter valve technology for structural heart disease has led to heightened scrutiny of outcomes following surgical valve replacement. Here, we review a manuscript by Tsubota et al. in the Journal of Cardiac Surgery detailing a single-center, retrospective cohort study of patients undergoing mitral valve replacement from 2007 to 2018. While outcomes appear to be excellent, these results should be carefully interpreted in light of limited data regarding the propensity score match methodology utilized., (© 2021 Wiley Periodicals LLC.)

Intimate partner violence (IPV) is a national and international public health and human rights concern. Immigrant women are disproportionately affected by IPV that includes homicides. This study explored the perspectives of survivors of IPV, who are immigrants to the United States, regarding their sources of strength that enhance their safety and promote coping in abusive relationships. Data for this qualitative study were collected from ethnically diverse immigrant women residing in Massachusetts, Arizona, Virginia, Washington, D.C., New York, Minnesota, and California, using purposive and snowball sampling techniques. Eighty-three in-depth interviews were conducted with adult immigrant survivors of IPV who self-identified as Asian ( n = 30), Latina ( n = 30), and African ( n = 23). Data were analyzed using thematic analysis. Women identified both external (e.g., community support, support from social service agencies) and internal (e.g., optimism, faith, beliefs) sources of strength. The study highlights how these sources can adequately address needs of survivors and offers areas for improvement in services for survivors. The findings are informative for practitioners serving immigrant survivors of IPV in legal, social service, and physical and mental health settings., Competing Interests: Declaration of Conflicting Interests The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Patient centred care (PCC) positively influences individual and organisational outcomes. It is important that dietitians working in rehabilitation units are supported to deliver PCC because effective rehabilitation is a collaborative and patient centred process. The objective of this scoping review was to explore the literature available regarding the delivery of dietetic PCC, with patients undergoing rehabilitation in subacute inpatient units., Methods: PubMed, MEDLINE, CINAHL, Embase and Scopus were searched for relevant published literature. Searches for grey and unpublished literature were also completed. Studies were eligible for inclusion and data extraction if they demonstrated the delivery of PCC by qualified dietitians, through individual consultations with adult patients undertaking subacute rehabilitation., Results: Overall, 675 studies were identified and six were included in the review. From the literature available, documentation was lacking regarding conceptualisation and delivery of patient centred nutrition care, with only one study providing quality indicators for patient centred dietetic services. Elements of PCC cited were mostly limited to phrases such as, 'individualised care', 'tailored advice', 'follow-up' and 'team collaboration'., Conclusions: This scoping review identified a considerable gap in the literature regarding the delivery of dietetic PCC in subacute rehabilitation units. Contemporary descriptions of PCC show that the delivery of care which is truly patient centred is far more comprehensive than individualising interventions or organising ongoing services. This raises the question: is the delivery of nutrition care in subacute rehabilitation unit's patient centred?, (© 2021 The British Dietetic Association.)

Background: Expanding access to sterile syringes in rural areas is vital, as injection-related epidemics expand beyond metropolitan areas globally. While pharmacies have potential to be an easily accessible source of sterile syringes, research in cities has identified moral, legal and ethical barriers that preclude over-the-counter (OTC) sales to people who inject drugs (PWID). The current study builds on prior urban-based research by elucidating (1) pharmacy OTC policies and (2) pharmacists' rationale for, and barriers and facilitators to, OTC syringe sales in a US rural area hard hit by drug-related epidemics., Methods: We conducted 14 semi-structured interviews with pharmacists recruited from two Eastern Kentucky health districts. Interview domains included experiences with, and attitudes toward, selling OTC syringes to PWID. Constructivist grounded theory methods were used to analyze verbatim transcripts., Results: Most pharmacists operated "restrictive OTC" pharmacies (n = 8), where patients were required to have a prescription or proof of medical need to purchase a syringe. The remainder (n = 6) operated "open OTC" pharmacies, which allowed OTC syringe sales to most patients. Both groups believed their pharmacy policies protected their community and pharmacy from further drug-related harm, but diverging policies emerged because of stigma toward PWID, perceptions of Kentucky law, and belief OTC syringe sales were harmful rather than protective to the community., Conclusion: Our results suggest that restrictive OTC pharmacy policies are rooted in stigmatizing views of PWID. Anti-stigma education about substance use disorder (SUD), human immunodeficiency virus (HIV), and Hepatitis C (HCV) is likely needed to truly shift restrictive pharmacy policy., (© 2022.

Appalachian Kentucky was at the epicenter of the prescription opioid epidemic in the early 2000's. As we enter the third decade of the epidemic, patterns have begun to emerge as people who use drugs (PWUD) transition from use of opioids to other drugs. The purpose of this analysis was to examine longitudinal changes in methamphetamine use in an ongoing cohort of rural people who use drugs (PWUD) in Appalachian Kentucky. All but five of the cohort participants ( N = 503) reported nonmedical prescription opioid use (NMPOU) at baseline and those 498 are included in this longitudinal analysis encompassing eight waves of data (2008-2020). Past 6-month use of methamphetamine was the dependent variable. Given the correlated nature of the data, mixed effects logistic regression was utilized to examine changes in methamphetamine use over time. Significant increases in methamphetamine use were observed over the past decade in this cohort of PWUD, especially in recent years (2017-2020). Prevalence of recent use at baseline and each of the follow-up visits was as follows: 9.4, 5.6, 5.0, 5.4, 8.1, 6.8, 6.9, and 33.1%, respectively ( p < 0.001). On the contrary, significant reductions in NMPO and heroin use were observed in the same time period. The odds of methamphetamine use at the most recent visit were 25.8 times greater than at baseline (95% CI: 14.9, 44.6) and 52.6% of those reporting methamphetamine use reported injecting the drug. These results provide further evidence of "twin epidemics" of methamphetamine use among NMPOU. While problematic on several fronts, of particular concern is the lack of effective treatment options for methamphetamine use disorder. As policies around the opioid epidemic continue to evolve, particular attention should be paid to the surge in stimulant use in opioid-endemic areas., Competing Interests: The 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 © 2022 Havens, Knudsen, Strickland, Young, Babalonis, Lofwall and Walsh.)

Purpose: Rural areas of the United States have experienced outbreaks of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infections among people who use drugs (PWUD). Pharmacy-based interventions may play a crucial role in prevention and entry into care, especially when traditional health care access is limited. The willingness of rural PWUD to use pharmacies for HIV/HCV-related services remains unknown. The purpose of this study was to describe the factors associated with the perceived likelihood of participating in free pharmacy-based HIV and HCV testing among PWUD living in rural Kentucky., Methods: Baseline data from the CARE2HOPE study in five Appalachian counties in eastern Kentucky were used. Participants were recruited using respondent-driven sampling and completed interviewer-administered surveys. Guided by the Andersen and Newman Framework of Health Services Utilization, we examined distributions and correlates of items regarding willingness to participate in free pharmacy-based HIV/HCV testing using logistic regression. Analyses included individuals who reported being HIV (N = 304) or HCV (N = 185) negative., Findings: Seventy-five percent of PWUD reported being "very likely" to participate in free pharmacy-based HIV testing and 80% for HCV testing. Two factors were associated with being less willing to participate in free HIV testing: PWUD who previously tested for HIV (OR: 0.47, CI: 0.25-0.88) and PWUD who obtained a high school diploma or equivalent compared to those who completed less (OR: 0.50, CI: 0.26-0.99)., Conclusion: Free pharmacy-based HIV and HCV testing was invariably acceptable among most of the rural PWUD in our sample, suggesting that pharmacies might be acceptable testing venues for this population., (© 2021 National Rural Health Association.)

Existing literature attests to water, sanitation, and hygiene (WASH) inequities among people experiencing homelessness (PEH) in the United States, but there is a dearth of research on such issues in rural areas. Homelessness is an emerging public health concern in rural areas where homelessness is on the rise, infectious disease outbreaks are becoming increasingly common, and PEH face unique WASH-related challenges compared to their urban counterparts. We conducted an exploratory study to understand the impacts of unmet WASH needs among rural PEH and their intersection with drug use through in-depth interviews (n = 10). Eligible participants were 18 years or older, lived in one of five Central Appalachian counties, and had experienced homelessness in the previous six months. Using thematic analysis, we identified factors that inhibit WASH access, and adverse health and well-being outcomes that result from unmet WASH needs. We also explore how WASH experiences compare among rural PEH who self-reported drug use to those who did not. Our findings revealed that factors at multiple levels inhibited WASH access, including stigma and place-based characteristics, which contributed to the adverse physical, mental, and emotional health of PEH. Comparisons between PEH who used drugs to those that did not revealed the intricate relationship between WASH, homelessness, and substance use in communities impacted by the opioid epidemic. Expanded WASH facilities that are safe and available with no prerequisites can address inadequate access among rural PEH and collaboration with harm reduction services may be advantageous to reach those who inject drugs., Competing Interests: Competing interests: The authors have declared that no competing interests exist.

Background: Despite high morbidity and mortality among people who use drugs (PWUD) in rural America, most research is conducted within urban areas. Our objective was to describe influencing factors, motivations, and barriers to research participation and retention among rural PWUD., Methods: We recruited 255 eligible participants from community outreach and community-based, epidemiologic research cohorts from April to July 2019 to participate in a cross-sectional survey. Eligible participants reported opioid or injection drug use to get high within 30 days and resided in high-needs rural counties in Oregon, Kentucky, and Ohio. We aggregated response rankings to identify salient influences, motivations, and barriers. We estimated prevalence ratios to assess for gender, preferred drug use, and geographic differences using log-binomial models., Results: Most participants were male (55%) and preferred methamphetamine (36%) over heroin (35%). Participants reported confidentiality, amount of financial compensation, and time required as primary influential factors for research participation. Primary motivations for participation include financial compensation, free HIV/HCV testing, and contribution to research. Changed or false participant contact information and transportation are principal barriers to retention. Respondents who prefer methamphetamines over heroin reported being influenced by the purpose and use of their information (PR = 1.12; 95% CI: 1.00, 1.26). Females and Oregonians (versus Appalachians) reported knowing and wanting to help the research team as participation motivation (PR = 1.57; 95% CI: 1.09, 2.26 and PR = 2.12; 95% CI: 1.51, 2.99)., Conclusions: Beyond financial compensation, researchers should emphasize confidentiality, offer testing and linkage with care, use several contact methods, aid transportation, and accommodate demographic differences to improve research participation and retention among rural PWUD., (© 2021.

The of this study aim was to develop a rapid method to determine the chemical composition, solvent evaporation rates, and polymerization kinetics of dental adhesives. Single-component, acetone-containing adhesives One-Step (OS; Bisco, Anaheim, CA, USA), Optibond Universal (OU; Kerr, Brea, CA, USA), and G-Bond (GB; GC, Tokyo, Japan) were studied. Filler levels were determined gravimetrically. Monomers and solvents were quantified by comparing their pure Attenuated Total Reflectance-Fourier Transform Infra-Red (ATR-FTIR) spectra, summed in different ratios, with those of the adhesives. Spectral changes at 37 °C, throughout passive evaporation for 5 min, then polymerisation initiated by 20 s, and blue light emitting diode (LED) (600 mW/cm 2 ) exposure ( n = 3) were determined. Evaporation and polymerisation extent versus time and final changes were calculated using acetone (1360 cm -1 ) and methacrylate (1320 cm -1 ) peaks. OS, OU, and GB filler contents were 0, 9.6, and 5.3%. FTIR suggested OS and OU were Bis-GMA based, GB was urethane dimethacrylate (UDMA) based, and that each had a different diluent and acidic monomers and possible UDMA/acetone interactions. Furthermore, initial acetone percentages were all 40-50%. After 5 min drying, they were 0% for OS and OU but 10% for GB. Whilst OS had no water, that in OU declined from 18 to 10% and in GB from 25 to 20% upon drying. Evaporation extents were 50% of final levels at 23, 25, and 113 s for OS, OU, and GB, respectively. Polymerisation extents were all 50 and 80% of final levels before 10 and at 20 s of light exposure, respectively. Final monomer polymerisation levels were 68, 69, and 88% for OS, OU, and GB, respectively. An appreciation of initial and final adhesive chemistry is important for understanding the properties. The rates of evaporation and polymerisation provide indications of relative required drying and light cure times. UDMA/acetone interactions might explain the considerably greater drying time of GB.

Aim: Models of hospital malnutrition care reliant on dietitians can be inefficient and of limited effectiveness. This study evaluated whether implementing the Systematised, Interdisciplinary Malnutrition Program for impLementation and Evaluation (SIMPLE) improved hospital nutrition care processes and patientreported experiences compared with traditional practice., Methods: A multi-site (five hospitals) prospective, pre-post study evaluated the facilitated implementation of SIMPLE, a malnutrition care pathway promoting proactive nutrition support delivered from time of malnutrition screening by the interdisciplinary team, without need for prior dietetic assessment. Implementation was tailored to local site needs and resources. Nutrition care processes delivered to inpatients who were malnourished or at-risk of malnutrition were identified across diagnosis, intervention, and monitoring domains using standardised audits from medical records, foodservice systems and patient-reported nutrition experience measures., Results: Pre-implementation (n = 365) and post-implementation (n = 397) cohorts were similar for age (74 vs 73 years), gender (47.1% vs 48.6% female), and nutrition risk status (46.6% vs 45.3% at-risk). Post-implementation, at-risk participants were more likely to receive enhanced food and fluids (68.5% vs 83.9%; P < .01), nutrition information (30.9% vs 47.2%; P < .01), mealtime assistance where required (61.4% vs 77.9% P = .04), nutrition monitoring (25.2% vs 46.3%; P < .01) and care planning (17.8% vs 27.7%; P = .01). Patient-reported nutrition experience measures confirmed improved nutrition care. There was no difference in dietetic occasions of service per patient (1.51 vs 1.25; P = .83)., Conclusions: Tailored SIMPLE implementation improves nutrition care processes and patient reported nutrition experience measures for at-risk inpatients within existing dietetic resources., (© 2021 Dietitians Australia.)

Background: Primary care providers (PCPs), including pediatricians and general practitioners, are often the first to see children with eczema/atopic dermatitis (AD). Little is known about management of pediatric AD by PCPs and adherence to national guidelines., Objective: To review existing literature examining management components of pediatric AD (topical corticosteroids [TCS], topical calcineurin inhibitors [TCIs], antihistamines, bathing, emollients, and diet) by PCPs., Data Sources: PubMed/Medline and Embase., Study Eligibility Criteria: English-language articles dated 2015 to 2020 reporting outcomes addressing management of pediatric AD by PCPs., Study Appraisal and Synthesis Methods: Two authors independently screened titles/abstracts, reviewed full-text articles, extracted relevant data, and evaluated study quality. Disagreements were resolved by a third author., Results: Twenty articles were included. Surveys and national database analyses were the most common methodologies (n = 7 each). PCPs commonly prescribed TCS but had a preference for low-potency agents, overprescribed nonsedating antihistamines, and avoided TCIs. PCPs commonly recommended emollients, although this was not universal. Data characterizing nonmedication management were limited., Limitations: Most studies did not examine individual patient encounters, but rather relied on providers reporting their general behaviors. Provider behavior may vary based on country of practice., Conclusions and Implications of Key Findings: Knowledge and management gaps exist among PCPs in treating pediatric AD in key areas including knowledge of TCS safety profiles and prescribing of TCIs. The current literature is largely limited to small studies that evaluate prescribing behaviors with limited data characterizing nonmedication management, highlighting the need for future research in this area., (Copyright © 2021 Academic Pediatric Association.

The giant honey bee Apis dorsata is unusual in being able to forage during both the day and the night. To date, the extent of this unique nocturnal foraging behavior and the environmental factors correlating with it have not been deeply investigated. We conducted the first systematic investigation into the nocturnal behavior of A. dorsata in Southern India by tracking the daily and nightly foraging activity of A. dorsata colonies in an urban environment for 8 months, over multiple seasons and lunar cycles. We found strong evidence that A. dorsata can behave in a manner that is "cathemeral" (active over the entire diel cycle) when environmental illumination is sufficient for nocturnal flight. However, workers were not always active even when the environment should have been bright enough for them to forage, suggesting that their nocturnal foraging behavior was also affected by seasonal changes in resource availability. The foraging activity observed during the day versus twilight versus night differed between seasons; notably, nocturnal activity rates were higher than diurnal activity rates during the winter. We found that at our study site A. dorsata routinely exhibits both diurnal and crepuscular activity, foraging just as intensely during the short twilight hours as during the day. The high foraging activity observed during the twilight and nighttime hours shows that A. dorsata colonies can extend their foraging beyond the daylight hours and reveals that foraging during these dimly lit hours is an integral part of their foraging ecology. This evidence of the importance of nocturnal and crepuscular foraging by A. dorsata paves the way for future studies examining the role of this species in nocturnal pollination networks, the contribution of nocturnal foraging to colony-level nutrition and energy budget, and the evolution of this unusual behavior. Future work comparing nocturnal activity in light polluted urban environments versus unpolluted natural environments is particularly encouraged to determine the generalizability of these findings., Competing Interests: The authors have declared that no competing interests exist.

Studies aiming to construct risk networks have historically collected network members' names, demographic characteristics and relational data (i.e., type, strength, duration, frequency of interaction, and HIV-related risk behaviors between the pair). Due to difficulties in constructing risk networks stemming from partner anonymity and the use of nicknames, some studies also collect network members' screen names, phone numbers, physical attributes, and scars/tattoos to assist with entity resolution. In-depth interviews with 20 men who have sex with men and transgender women in Kentucky assessed privacy/confidentiality concerns as well as accuracy/recall issues associated with providing these details. Most preferred providing alters' nicknames/first names only or a first name with the first letter of the last name. Many perceived screen names, phone numbers, and scars/tattoos to be too personal/identifying. Willingness to provide more detailed information varied by relationship type/strength, which could influence the validity of the resulting network., Competing Interests: Declarations of interest: none

Background: Closed incision negative pressure wound therapy (ciNPWT) may reduce surgical site complications following total joint arthroplasty. Although unlikely necessary for all patients, the criteria for utilizing ciNPWT in primary total knee arthroplasty (TKA) remain poorly defined. This study's purpose was to compare the incidence of incisional wound complications, non-incisional complications (ie, dressing reactions), reoperations, and periprosthetic joint infections (PJIs) among a group of high-risk primary TKA patients treated with ciNPWT vs an occlusive silver impregnated dressing., Methods: One hundred thirty high-risk primary TKA patients treated with ciNPWT were 1:1 propensity matched and compared to a historical control group treated with an occlusive silver impregnated dressing. High-risk criteria included the following: active tobacco use, diabetes mellitus, body mass index >35 kg/m 2 , autoimmune disease, chronic kidney disease, Staphylococcus aureus nasal colonization, and non-aspirin anticoagulation., Results: Age, gender, and risk factor profile were comparable between cohorts. The ciNPWT cohort had significantly fewer incisional wound complications (6.9% vs 16.2%; P = .031) and significantly more non-incisional complications (16.9% vs 1.5%; P < .001). No dressing reactions required clinical intervention. There were no differences in reoperations or periprosthetic joint infections (P = 1.000). In multivariate analysis, occlusive silver impregnated dressings (odds ratio 2.9, 95% confidence interval 1.3-6.8, P = .012) and non-aspirin anticoagulation (odds ratio 2.5, 95% confidence interval 1.1-5.6, P = .028) were associated with the development of incisional wound complications., Conclusion: Among high-risk patients undergoing primary TKA, ciNPWT decreased incisional wound complications when compared to occlusive silver impregnated dressings, particularly among those receiving non-aspirin anticoagulation. Although an increase in dressing reactions was observed, the clinical impact was minimal., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Introduction: Acute oncology services (AOS) provide rapid review and expedited pathways for referral to specialist care for cancer patients. Blood tests may support AOS in providing estimates of prognosis. We aimed to develop and validate a prognostic model of 30-day mortality based on routine blood markers to inform an AOS decision to actively treat or palliate patients., Methods and Materials: Using clinical data from 752 AOS referrals, multivariable logistic regression analysis was conducted to develop a 30-day mortality prognostic model. Internal validation and then internal-external cross-validation were used to examine overfitting and generalizability of the model's predictive performance., Results: Urea, alkaline phosphatase, albumin and neutrophils were the strongest predictors of outcome. The model separated patients into distinct prognostic groups from the cross-validation (C Statistic: 0.70; 95% CI: 0.64-0.76). Admission year was included as a predictor in the model to improve the model calibration., Conclusion: The developed prediction model was able to classify patients into distinct prognostic risk groups, which is clinically useful for delivering an evidence-based AOS. Collation of data from other AOS centers would allow for the development of a more generalizable prognostic model.

The asymptomatic host range of Fusarium virguliforme includes corn, a common crop rotated with soybean that we hypothesize may alter F. virguliforme population dynamics and disease management. A field-based approach explored the temporal dynamics of F. virguliforme colonization of corn and soybean roots under different tillage and residue managements. Experiments were conducted in Iowa, Indiana, Michigan, and Wisconsin, United States and Ontario, Canada from 2016 to 2018. Corn and soybean roots were sampled at consecutive timepoints between 1 and 16 weeks after planting. DNA was extracted from all roots and analyzed by real-time quantitative PCR for F. virguliforme quantification. Trials were rotated between corn and soybean, containing a two-by-two factorial of tillage (no-tilled or tilled) and corn residue (with or without) in several experimental designs. In 2016, low amounts (approximately 100 fg per 10 mg of root tissue) of F. virguliforme were detected in the inoculated Iowa, Indiana, and Michigan locations and noninoculated Wisconsin corn fields. However, in 2017, greater levels of F. virguliforme DNA were detected in Iowa, Indiana, and Michigan across sampling timepoints. Tillage practices showed inconsistent effects on F. virguliforme root colonization and sudden death syndrome (SDS) foliar symptoms among trials and locations. However, residue management did not alter root colonization of corn or soybean by F. virguliforme . Plots with corn residue had greater SDS foliar disease index in Iowa in 2016. However, this trend was not observed across the site-years, indicating that corn residue may occasionally increase SDS foliar symptoms depending on the disease level and soil and weather factors.

Background: Patients with cancer have an increased risk of venous thromboembolism (VTE) and it is commonly detected incidentally. The outcomes and optimal management for patients with cancer and incidental VTE remain debated., Objectives: We conducted a systematic review and meta-analysis to evaluate the outcomes in patients with cancer and incidentally detected VTE compared to those with symptomatic events., Patients/methods: We searched the electronic databases and included randomized controlled trials (RCTs) and observational studies reporting recurrent VTE, major bleeding events, and mortality in patients with cancer and incidental VTE compared to symptomatic VTE., Results: We included 23 studies for the systematic review: 3 RCTs and 20 observational studies. The meta-analysis of the 3 RCTs showed a significantly lower rate of VTE recurrence at 6 months in patients with incidental VTE compared to those with symptomatic VTE (relative risk [RR] 0.62, 95% confidence interval [CI] 0.44-0.87). The risk of major bleeding events at 6 months was numerically higher with incidental VTE compared to symptomatic VTE (RR 1.47, 95% CI 0.99-2.20). There was no difference in overall mortality., Conclusions: Among patients with cancer, incidental VTE was associated with a lower rate of VTE recurrence compared to symptomatic VTE, with a trend in increased major bleeding events. The risk-benefit ratio of anticoagulation may differ between incidental and symptomatic events and should be considered in patient management., (© 2021 International Society on Thrombosis and Haemostasis.)

Objectives: To assess the influence of systematically varying concentrations of 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) versus 3% 4-META on the polymerisation kinetics and shrinkage, biaxial flexural strength (BFS) and modulus of remineralising composites., Methods: Composites were prepared by adding poly(propylene glycol) dimethacrylate (24 wt%), camphorquinone (1 wt%) and MDP (0%, 5%, 10%, 15% and 20 wt%) or 4-META (3%) to urethane dimethacrylate. These were mixed with glass fillers containing 8 wt% monocalcium phosphate and 4 wt% polylysine (powder-liquid ratio of 3:1). Continuous spectral changes, following 20 s light exposure (37 °C), were assessed with an ATR-FTIR to monitor polymerisation kinetics (n = 3). Final extrapolated conversions (D C,max ) were employed to calculate polymerisation shrinkage. BFS and modulus of 24-h dry stored disc specimens (10 × 1 mm; n = 10) were determined using a ball-on-ring jig setup., Results: Maximum rate of polymerisation and D C,max increased linearly from 2.5 to 3.5% s -1 and 67 to 83%, respectively, upon increasing MDP from 0 to 20 wt%. Values with 3% 4-META were 2.6% s -1 and 78%. Shrinkage was 3.8 ± 0.3% for all formulations. Raising 4-META or MDP from 0 to 3 versus 5%, respectively, increased strength from 106 to 145 versus 136 MPa. A decreasing trend with higher MDP concentrations was noted. Elastic modulus showed no specific trend upon MDP increase., Significance: Whilst final conversion levels were enhanced by 3% 4-META or >5% MDP, trends did not correlate with strength. Peak strengths with 3% 4-META or 5% MDP may therefore be due to acidic monomers providing linkage between the hydrophilic, non-silane treated particles and the polymer matrix., (Copyright © 2021 The Academy of Dental Materials.

Cancer mortality rates in low-income and middle-income countries (LMICs) are unacceptably high, requiring both collaborative global effort and in-country solutions. Experience has shown that working together in policy, clinical practice, education, training, and research leads to bidirectional benefit for LMICs and high-income countries. For over 60 years, the UK National Health Service has benefited from recruitment from LMICs, providing the UK with a rich diaspora of trained health-care professionals with links to LMICs. A grassroots drive to engage with partners in LMICs within the UK has grown from the National Health Service, UK academia, and other organisations. This drive has generated a model that rests on two structures: London Global Cancer Week and the UK Global Cancer Network, providing a high-value foundation for international discussion and collaboration. Starting with a historical perspective, this Series paper describes the UK landscape and offers a potential plan for the future UK's contribution to global cancer control. We also discuss the opportunities and challenges facing UK partnerships with LMICs in cancer control. The UK should harness the skills, insights, and political will from all partners to make real progress., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2021 Elsevier Ltd.

Objectives: The overall goal of the Kentucky Viral Hepatitis Treatment Study (KeY Treat) is to eliminate hepatitis C transmission from a county in Appalachian Kentucky by removing the barriers to accessing hepatitis C virus (HCV) treatment., Methods/analysis: KeY Treat is a phase IV, open-label, single-arm clinical trial of sofosbuvir/velpatasvir (SOF/VEL) for the treatment of viraemic HCV infections. Those eligible for KeY Treat are at least 18 years of age, viraemic and are residents of the target county. Pregnant women are not eligible. Rapid HCV RNA screening is used to determine eligibility, and those with a quantifiable viral load (VL) consenting to participate initiate SOF/VEL on the same day. All pharmacologic treatment and related medical care is provided free of charge using a non-specialist provider model. Follow-up visits occur at 2, 6 and 12 weeks during treatment to assess medication adherence (measured via VL and self-report), side effects and engagement in risk behaviours. Post-treatment visits occur at 12 weeks (sustained virologic response (SVR12) visit), 6 months and 12 months post-treatment completion to assess re-infection. A control county has also been identified, and prevalence and incidence of chronic HCV infections will be compared with the target community longitudinally. The primary outcome to assess elimination is SVR12. However, several outcomes will be measured to assess the effectiveness of removing the barriers to HCV treatment, including treatment entry, completion and re-infection. Analyses will be conducted via a generalised linear model framework that can incorporate flexible covariate adjustment and multiple outcome types with a compatible link function. Mathematical modelling will be completed assessing the impact and cost-effectiveness of the intervention., Ethics and Dissemination: KeY Treat has been approved by the Institutional Review Board at the University of Kentucky. Results from KeY Treat will be presented at conferences and published in peer-reviewed journals., Trial Registration Number: NCT03949764., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Aim: Implementation science theories, models and frameworks help to address evidence-practice gaps, which have increasing importance for dietetic practice. This paper aims to provide dietitians with insight into how implementation science can be applied to practice, using multiple 'real-life' case studies., Methods: Three case studies were purposively selected across areas of dietetics practice to demonstrate application of commonly-used implementation theories, models and frameworks. Reflections from the authors were provided in response to a structured set of questions outlining how the theoretical approach was selected and used, and considerations for future application. Within and cross-case analysis was undertaken., Results: Dietitians used diverse implementation theories, models and frameworks to identify barriers and enablers, to plan for implementation, and to guide the selection of implementation strategies. Implementation theory was used to evaluate the implementation process in one case study. Cross-case analysis identified that mentoring by those with implementation expertise, multidisciplinary implementation teams, and leadership and investment in research and translation at an organisational and departmental level as key enablers., Conclusions: This paper offers dietitians insight into how implementation science can be applied to improve the uptake of evidence-based practices within nutrition and dietetics, and suggests that there needs to be investment in implementation science as a foundation science within nutrition and dietetics, including education, training and mentoring for dietitians., (© 2021 Dietitians Australia.)

Background and Aims: Recent reports have highlighted the emergence of 'wasp dope' as an issue of concern, but epidemiological evidence is lacking. Wasp dope is a crystalline substance created by electrifying pyrethroid-containing insecticides (e.g. wasp sprays) that may give users a methamphetamine-like 'rush'. This paper describes wasp dope use and correlates of use in a sample of people who use drugs (PWUD) in Appalachian Kentucky, a region that has been an epicenter of opioid use and related harms in the United States., Methods: Respondent-driven sampling and targeted street outreach were used to recruit PWUD. Eligibility criteria included being aged at least 18 years, residing in one of five Appalachian Kentucky counties, and having either used opioids or injected any drug to get high in the prior 30 days. Interviewer-administered surveys queried participants' (n = 278) recent (past 6 months) wasp dope use, other substance use and demographic characteristics. Prevalence ratios (PR) were estimated using generalized estimating equations assuming a Poisson outcome distribution in a cross-sectional analysis., Results: Recent wasp dope use was reported by 16.1% of participants. Men and people who recently experienced homelessness and transportation difficulties were twice or more as likely to have used wasp dope compared with their counterparts [PR = 2.08, 95% confidence interval (CI) = 1.11, 3.87, PR = 2.78, 95% CI = 1.64, 4.72 and PR = 2.01, 95% CI = 1.06-3.81, respectively]. While wasp dope use was associated with injection drug use and using opioids and other substances to get high in unadjusted analyses, the factor most strongly associated with wasp dope use was methamphetamine use (PR = 17.23, 95% CI = 2.57, 115.61), specifically methamphetamine injection (PR = 4.47, 95% CI = 1.56, 12.78)., Conclusions: Among people who use drugs in rural Kentucky, USA, more than one in six people surveyed reported using wasp dope in the past 6 months, nearing the percentage using cocaine/crack (20%) and fentanyl/carfentanil (25%). Wasp dope use was higher among men and strongly associated with homelessness, transportation access, methamphetamine use and injection drug use., (© 2020 Society for the Study of Addiction.)

Background: Enrolling sufficient number of people who inject drugs (PWID) into syringe services programs (SSP) is important to curtail outbreaks of drug-related harms. Still, little is known about barriers and facilitators to SSP enrollment in rural areas with no history of such programs. This study's purpose was to develop a grounded theory of the role of the risk environment and individual characteristics of PWID in shaping SSP enrollment in rural Kentucky., Methods: We conducted one-on-one semi-structured interviews with 41 clients of 5 SSPs that were established in rural counties in Appalachian Kentucky in 2017-2018. Interviews covered PWID needs, the process of becoming aware of SSPs, and barriers and facilitators to SSP enrollment. Applying constructivist grounded theory methods and guided by the Intersectional Risk Environment Framework (IREF), we applied open, axial and selective coding to develop the grounded theory., Results: Stigma, a feature of IREF's meso-level social domain, is the main factor hampering SSP enrollment. PWID hesitated to visit SSPs because of internalized stigma and because of anticipated stigma from police, friends, family and healthcare providers. Fear of stigma was often mitigated or amplified by a constellation of meso-level environmental factors related to healthcare (e.g., SSPs) and social (PWID networks) domains and by PWID's individual characteristics. SSPs mitigated stigma as a barrier to enrollment by providing low threshold services in a friendly atmosphere, and by offering their clients program IDs to protect them from paraphernalia charges. SSP clients spread positive information about the program within PWID networks and helped their hesitant peers to enroll by accompanying them to SSPs. Individual characteristics, including child custody, employment or high social status, made certain PWID more susceptible to drug-related stigma and hence more likely to delay SSP enrollment., Conclusions: Features of the social and healthcare environments operating at the meso-level, as well as PWID's individual characteristics, appear to enhance or mitigate the effect of stigma as a barrier to SSP enrollment. SSPs opening in locations with high stigma against PWID need to ensure low threshold and friendly services, protect their clients from police and mobilize PWID networks to promote enrollment.

Investigation of polymerisation kinetics using ATR-FTIR systems is common in many dental studies. However, peak selection methods to calculate monomer-polymer conversion can vary, consequently affecting final results. Thus, the aim of this study is to experimentally confirm which method is less prone to systematic errors. Three commercial restorative materials were tested-Vertise Flow (VF), Constic and Activa Bioactive Restorative Kids. Firstly, Attenuated Total Reflectance Fourier Transform Infra-Red (ATR-FTIR) (Spectrum One, Perkin-Elmer, UK) spectra of monomers were acquired-10-methacryloyloxy decyl dihydrogen phosphate (10-MDP), bisphenol-A glycidyl dimethacrylate (Bis-GMA), 2-hydroxyethyl methacrylate (HEMA), triethyelene glycol dimethacrylate (TEGDMA) and urethane dimethacrylate (UDMA) to investigate proportionality of methacrylate peak heights versus concentration. Spectral changes upon light exposure of 2 mm discs of the restorative materials (irradiated for 20 s, LED curing unit 1100-1330 mW/cm2) were assessed to study polymerisation kinetics (n = 3), with continuous acquisition of spectra, before, during and after light exposure. Peak differences and degrees of conversion (DC %) were calculated using 1320/1336, 1320/1350 and 1636/1648 cm-1 as reaction/reference peaks. Inferential statistics included a MANOVA and within-subjects repeated measures ANOVA design (5% significance level). Proportionality of methacrylate peak height to concentration was confirmed, with the 1320/1352 cm-1 peak combination showing the lowest coefficient of variation (8%). Difference spectra of the polymerisation reaction showed noise interference around the 1500-1800 cm-1 region. Across the different materials, DC % results are highly dependent upon peak selection (p<0.001), with higher variability associated to the 1636 cm-1. Significant differences in the materials were only detected when the 1320 cm-1 peak was used (p<0.05). Within the same materials, methods were significantly different for Constic and Activa (p<0.05). It is possible to conclude that the 1320 cm-1 peak is more adequate to assess polymerisation of methacrylates and is therefore recommended., Competing Interests: The authors have declared that no competing interests exist.

Background and Aims: The US opioid crisis has led to increases in overdose fatalities and the incidence of HIV, hepatitis C and other infections. This analysis examines social network predictors of recent (self-report injection followed by non-injection) and sustained (self-report non-injection at two consecutive visits among those who previously injected) injection cessation in Appalachian Kentucky., Design: Data were collected through bi-annual longitudinal assessments for Social Networks among Appalachian People (SNAP; 2008-17). Using logistic regression with generalized estimating equations that clustered on individuals, we regressed non-injection status on the number of social network members who (a) did not inject and (b) recently stopped injecting and tested for interactions between each social network exposure and prior non-injection status. Social network exposures were self-reported., Setting: Rural eastern Kentucky, USA., Participants: Participants entered the analysis only after reporting recent injection and had to have had at least two consecutive study visits (n = 326)., Measurements: Interviewer-administered surveys collected individual-level socio-demographics, recent (past 6 months) drug use behaviors and the names of recent social support, sex and drug-use partners., Findings: After adjusting for confounders, the number of non-injecting social network members was positively associated with recent/sustained injection cessation (adjusted odds ratio = 1.27; 95% confidence interval = 1.13-1.42) and having more social network members was associated with reduced odds of recent/sustained injection cessation. The number of previously injecting social network members who had recently stopped injecting was not statistically significantly associated with injection cessation. Neither of the interactions we tested for was statistically significant, suggesting that the relationships may be similar for those who recently stopped injecting versus had not injected for at least 1 year., Conclusions: For each additional network member who did not inject drugs, there was an increased odds of recent and sustained injection cessation among people with a history of injection drug use in Appalachian Kentucky., (© 2020 Society for the Study of Addiction.)
