Reasons for performing study To add to the existing data on impact loading of the metacarpophalangeal ( MCP) joint as a precursor to assessing the potential role of impact in joint disease. Objectives To examine the effect of impact loading on contact areas of the first phalanx ( P1) and proximal sesamoids ( PS) with the third metacarpal ( McIII) under 3 hoof-strike conditions (toe-first, flat, heel-first). Study design Randomised, repeated controlled experiment using cadaver material. Methods Eight cadaver limbs were subjected to randomised, repeated controlled trials where the hoof was struck by a pendulum impact machine (impact velocity 3.55 m/s) under 3 strike conditions. Data from pressure sensitive film placed over medial and lateral McIII condyles and lateromedially across the dorsal aspect of McIII were quantified: total areas of P1 and PS contact (cm2) at maximum recorded pressure; centroid locations of contact areas relative to the sagittal ridge (cm) and transverse ridge (cm) and dispersion of pixels (cm4) for each McIII condyle (medial/lateral). The effect of the strike conditions on each variable were statistically tested using repeated-measures ANOVA (α = 0.05). Results Contact area between P1 and McIII condyles fell in well-defined areas bounded by the sagittal and transverse ridge, contact areas from PS were smaller and widely dispersed across McIII palmar border. Ratio of contact area of P1 to PS was 2.83 (P<0001). Hoof strike had no significant effect on contact area ( P>0.54) Conclusions Contact at impact (primarily from P1 and distally situated on McIII), contrasts with contact areas at midstance from both P1 and PS, symmetrically placed. Under impact, the greatest contact area was on the dorsal aspect of the medial condyle and coincides with the area subjected to the greatest increase in subchondral bone stiffening in joint disease.

Reasons for performing study We wished to add to the existing baseline data on impact loading of the distal limb as a precursor to assessing the potential role of impact in injury and joint disease. Objectives To examine the effect of 3 hoof-strike conditions (toe first, flat and heel first) and 2 specimen masses (with and without a ballast of ∼2% body mass) on impact deceleration and vibration frequencies and energies at the hoof, first phalanx and third metacarpal. Study design Biomechanical experiments in cadaver material. Methods Eight cadaver limbs were subjected to randomised, repeated controlled trials, in which the hoof was struck by a pendulum impact-testing machine (impact velocity, 3.55 m/s) in the 3 strike and 2 mass conditions. Data from triaxial accelerometers on the hoof, first phalanx and third metacarpal quantified, for all trials, the peak impact acceleration, frequencies in the first 6.4 ms following impact, the frequency with the most energy, 95% of the total energy and the frequency at 95% cumulative energy. The effects of the strike and mass conditions on each variable were statistically tested using repeated-measures ANOVA (α = 0.05). Results Signal energy reaching the third metacarpal was 6-31% of that at the hoof. A heel-first strike produced the largest peak accelerations and highest frequencies among all strike conditions, and changing the mass had no effect regardless of strike condition. Conclusions Large accelerations that occur upon impact of the hoof with the ground are attenuated by the distal structures of the equine limb, but still carry considerable energy within the signal that could be damaging to tissue and are dependent on hoof-strike condition but not ballast. Our results suggest that impact loading on the hoof could be a factor in contributing to bone injury and joint disease in the distal limb. [ABSTRACT FROM AUTHOR]

The use of conventional logical connectives either in logic, in mathematics, or in both cannot determine the meanings of those connectives. This is because every model of full conventional set theory can be extended conservatively to a model of intuitionistic set plus class theory, a model in which the meanings of the connectives are decidedly intuitionistic and nonconventional. The reasoning for this conclusion is acceptable to both intuitionistic and classical mathematicians. En route, I take a detour to prove that, given strictly intuitionistic principles, classical negation cannot exist.

Background: Management of the in-season athlete presenting with an anterior shoulder dislocation is a nuanced process that continues to be refined. Options and pathways between nonoperative and operative treatment have undergone many iterations over a century of orthopedic research and advancement. It requires an understanding of sport-specific demands and the individual athlete's goals. The orthopedic surgeon must have mastery of the natural history, treatment options, and outcomes of anterior shoulder dislocations. Balance of these factors is delicate and highly individualized for each athlete, and is why management of the in-season athlete with an anterior shoulder dislocation remains an art for the orthopedic surgeon., Materials and Methods: A narrative review of the literature regarding the in-season athlete with anterior shoulder dislocation was conducted of the PubMed, Embase, and Cochrane databases. The findings are summarized in this article., Results: Multiple studies have investigated management of the in-season athlete with anterior shoulder dislocation. Treatment is highly individualized for each athlete and their respective circumstances. Nonoperative treatment remains the only option for athletes that seek to return to play in the same season, however with a high risk of recurrence. Operative treatment has a track record of success in terms of returning to high level of play and lower recurrence, but would preclude a return to competition in the same season., Conclusions: Management of the in-season athlete with anterior shoulder dislocation remains a challenging issue without consensus recommendation among shoulder surgeons. Much has been done to understand the pathology and delineate indications for nonoperative treatment and surgical management. Although recurrence and return to play rates have improved with each iteration, recurrent instability and revision surgery continue to occur at high rates. Therefore, additional work remains to optimize return to play as well as long-term outcomes for athletes., (Copyright © 2024 Journal of Shoulder and Elbow Surgery Board of Trustees.

Highly pathogenic H5N1 (HP H5N1) influenza A virus (IAV) has been detected annually in North American ducks since its introduction during 2021, but it is unknown if this virus will follow the same seasonal and geographic patterns that have been observed with low-pathogenicity (LP) IAV in this reservoir. We monitored blue-winged teal in the Mississippi flyway prior to the detection of HP H5N1 and during two post-introduction migration cycles from spring 2022 to spring 2024, testing birds for infection and antibodies to IAV nucleoprotein (NP), hemagglutinin subtype H5, and neuraminidase subtype N1. Antigens representing clade 2.3.4.4b HP H5 and LP North American H5 were used for hemagglutination inhibition (HI) and virus neutralization (VN) tests for H5 antibodies. Virologic results were consistent with historic seasonal and geographic patterns reported for LP IAV with peak infections occurring in pre-migration staging areas in Minnesota during fall 2022. However, the high prevalence of the H5 subtype was exceptional compared to historic prevalence estimates at this same site and for the Mississippi flyway. HP H5N1 was detected on wintering areas in Louisiana and Texas during the fall of that same year and this was followed by an increase in estimated antibody prevalence to NP, H5, and N1 with no HP H5N1 detections during the wintering or spring migration periods of 2022/2023. HP H5N1 was not detected in Minnesota during fall 2023 but was detected from a single bird in Louisiana. However, a similar increase in antibody prevalence was observed during the winter and spring period of 2023 and 2024. Over the two migration cycles, there was a temporal shift in observed prevalence and relative titers against the H5 antigens with a higher proportion of ducks testing positive to the 2.3.4.4b H5 antigen and higher relative titer to that antigen compared to the representative LP North American H5 antigen. The seasonal and geographic patterns observed appear to be driven by population immunity during the migration cycle. Results support an initial high infection rate of HP H5N1 in blue-winged teal in the Mississippi flyway followed by a high prevalence of antibodies to NP, H5, and N1. Although prevalence was much reduced in the second migration cycle following introduction, it is not known if this pattern will persist in the longer term or affect historic patterns of subtype diversity in this reservoir.

Evaluating research activity in research departments and education programs is conventionally accomplished through measurement of research funding or bibliometrics. This limited perspective of research activity restricts a more comprehensive evaluation of a program's actual research capacity, ultimately hindering efforts to enhance and expand it. The objective of this study was to conduct a scoping review of the existing literature pertaining to the measurement of research productivity in research institutions. Using these findings, the study aimed to create a standardized research measurement tool, the Productivity And Capacity Evaluation in Research (PACER) Tool. The evidence review identified 726 relevant articles in a literature search of PubMed, Web of Science, Embase, ERIC, CINAHL, and Google Scholar with the keywords "research capacity" and "research productivity." Thirty-nine English-language studies applicable to research measurement were assessed in full and 20 were included in the data extraction. Capacity/productivity metrics were identified, and the relevance of each metric was data-charted according to 3 criteria: the metric was objective, organizational in scale, and applicable to varied research domains. This produced 42 research capacity/productivity metrics that fell into 7 relevant categories: bibliometrics, impact, ongoing research, collaboration activities, funding, personnel, and education/academics. With the expertise of a Delphi panel of researchers, research leaders, and organizational leadership, 31 of these 42 metrics were included in the final PACER Tool. This multifaceted tool enables research departments to benchmark research capacity and research productivity against other programs, monitor capacity development over time, and provide valuable strategic insights for decisions such as resource allocation., Competing Interests: Conflict of interest: The authors report no financial conflicts of interest., (© Copyright by the American Board of Family Medicine.)

Background: Clinical Ethics Consultations (CECs) are used by healthcare systems to offer healthcare practitioners a structured level of support to approach ethical questions. The objective of this study was to detail the elements of surveyed CECs and offer guidance in the approach to future ethics consultations at a regional healthcare system., Methods: This cohort study has a qualitative and quantitative retrospective approach, surveying ethics consultations through the dates of 4/27/22 to 4/26/24. A documentary sheet was created, and information was entered via online data-gathering forms. The cases are from a range of specialties within a regional healthcare system servicing Minnesota, Wisconsin, and North Dakota., Results: 103 CECs were performed within the study period across the regional healthcare system. Consultations were identified through retrospective review of the internal CEC database, and patient information was collected through the medical record. Decision-making was often performed by a substitute decision-maker (N = 54), occurring in 70.1% of cases with known decision makers. CECs were documented in an ethics-specific note in the patient medical record in 37 of 82 (45.1%) documented patient cases. It was common for physicians to mention the ethics consultation in their patient notes, occuring in 51 of 82 (62.2%) of documented patient cases. Age was recorded in 92.0% (N = 91) of unique patient cases; the median age was 62 years. Ethical questions concerning end-of-life care were the most common cause for consultation (N = 35, 34%), and CECs were most commonly requested in general medicine or hospitalist departments (N = 38, 45.2%). Most consultations resulted in resolution at time of initial consultation with the ethics call team., Conclusions: Recommendations for increased frequency and timing of policy review are given based on the results of the data presented. Using interpretation of the CECs in this study, we offer recommendations towards the use and documentation of ethics consultations in the era of open notes, open the door towards areas of future research, and ultimately promote use of CECs for more favorable patient outcomes., (© 2024.

Introduction: Threaded conical centrifuge tubes are ubiquitous in biological laboratories and are frequently used for the storage/transport of potentially biohazardous samples. However, limited data are available on how frequently and from where these tubes leak. These data are valuable for laboratory biorisk management and to inform future studies on risks arising from the routine use of laboratory consumables., Methods: The frequency of leaks from threaded conical centrifuge tubes was tested using a Glo Germ solution as a tracer. Conical tubes (15 and 50 mL) from several brands were filled, inverted, and placed on their side on the benchtop. After 1 h, the presence or absence of leaks on the benchtop surface, tube threads, and exterior was recorded., Results: We observed that liquid leaked out of tubes that were apparently properly threaded in 2% of 15 mL tubes (confidence interval [95% CI] 1.4-2.6) and 1.4% of 50 mL tubes (95% CI 0.2-1.5). After opening, liquid was found on the threads on the outside of the tube in 20% of 15 mL tubes (95% CI 10-31) and 14% of 50 mL tubes (95% CI 1-28). We did not find sufficient evidence that differences in leak rates among brands were practically significant., Conclusions: The fact that leaks were not uncommonly observed from conical centrifuge tubes suggests that mitigations for any hazard posed by a leak should be a component of every biorisk management strategy for protocols involving the manipulation of hazardous substances in these tubes. Further research should be conducted on other activities that could cause tubes to leak (such as centrifugation or vortexing) and should be completed to understand the risks associated with this consumable. Research into the costs and benefits of mitigating the risk of leaks from conical tubes is recommended., (Copyright 2024, ABSA International 2024.)

Background: Tuberculosis (TB) and depression are highly comorbid and linked to higher rates of death and disability. Several evidence-based treatments for depression have been successfully implemented in low- and middle-income countries, but more knowledge is needed on how to bring these innovations to scale within complex 'real world' public health systems., Objective: To explore whether the principles of social network analysis could be used to enhance receptivity to integrating depression treatment into primary care for individuals with and without TB in Brazil., Methods: We used existing scales to identify settings and providers with high receptivity and connectivity within the primary care network. We trained and supervised existing staff in three primary care sites to deliver a brief evidence-based intervention over one year, coupled with active dissemination activities. Afterwards, we reassessed receptivity among individuals involved, and not involved, in the pilot., Results: Highly significant changes were observed in mental health literacy, attitudes towards evidence-based practices, work self-efficacy, and implementation leadership supporting our hypothesis. Limited social connections between primary care clinics precluded the examination of the hypothesis that targeting settings with high connectivity could capitalize on the information flow between and transcend the decentralized structure of the network, but leveraging the centralized nature of the TB program to integrate mental health services emerged as a promising alternative., Conclusions: The findings of this study strongly suggest that social networks may be leveraged to change individual providers' attitudes, thereby contributing to the enhanced dissemination of evidence-based interventions., Competing Interests: CONFLICT OF INTEREST Dr. Milton Wainberg is on the Editorial Advisory Board of the Journal of Current Psychiatry Research and Reviews.

Prior research suggests COVID-19 has amplified stress on Academic Clinician Frontline-Workers (ACFW). The aim of this paper is: (1) to better understand the experiences of ACFW during the COVID-19 pandemic including their mental-emotional wellbeing, academic productivity, clinical experiences, and (2) to examine any gender differences. A cross-sectional survey was administered to University of Minnesota/M Health Fairview systems' faculty February-June 2021. Of the 291 respondents, 156 were clinicians, with 91 (58 %) identifying as Frontline-Workers (ACFW). Faculty wellbeing was assessed using validated measures in addition to measures of productivity and sociodemographics. For example, ACFW reported a higher Work-Family Conflict (WFC) scores compared to non-ACFW (26.5 vs. 24.1, p = 0.057) but did not report higher Family-Work Conflict (FWC) scores (17.7 vs. 16.3, p = 0.302). Gender sub-analyses, revealed that women ACFW compared to men ACFW reported higher WFC scores (27.7 vs. 24.1, p = 0.021) and FWC (19.3 vs. 14.3, p = 0.004). Academically, ACFW reported submitting fewer grants and anticipated delays in promotion and tenure due to the COVID-19 (p = 0.035). Results suggest COVID-19 has exacerbated ACFW stress and gender inequities. Reports of anticipated delay in promotion for ACFW may pose a challenge for the long-term academic success of ACFW, especially women ACFW. In addition, women may experience higher FWC and WFC as compared to men. Schools of academic medicine should consider re-evaluating promotion/tenure processes and creating resources to support women ACFW as well as ACFW caregivers., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Purpose: We visualized rural-urban differences in inpatient hospitalization and emergency department (ED) health care utilization (HCU) for older adults with dementia to understand the HCU of rural versus urban older adults in Minnesota and to examine in greater detail the variability of HCU in rural areas., Methods: For 3 older adult age groups, we utilized Healthcare Cost and Utilization Project (H-CUP) datasets from 2016 to 2018 to profile hospital admission rates, and ED visit rates related to dementia stratified by rurality and regions. Rates were visualized by spatial interpolation method. We then used logistic regression analysis adjusted by multiple covariates to evaluate rural-urban differences of the chance of having a dementia diagnosis in HCU., Findings: Minnesota rural areas showed 17.6% lower age-adjusted rate (AAR) of dementia mortality than urban areas. AARs of ED visits for dementia were 12.4% higher in rural ZIP codes, whereas AARs of hospitalization were 24.7% lower. After controlling for neighborhood-level risk factors, such as income, education, health behaviors, and provider access, the odds ratios of having dementia diagnosis are 12% lower if an ED visit patient lives in rural as opposed to an urban area (OR = 0.88, P<.0001)., Conclusions: In comparison to AAR, the fully adjusted data showed larger rural-urban predictors of having dementia diagnoses in hospitalizations and ED utilizations and demonstrated differences between AAR of ED visit and odds ratios of having dementia diagnosis. A regional comparison revealed that dementia ED visits were higher for Northeast MN compared to Minnesota's largest metropolitan region., (© 2022 The Authors.

Introduction: Snap-cap microcentrifuge tubes are ubiquitous in biological laboratories. However, limited data are available on how frequently splashes occur when opening them. These data would be valuable for biorisk management in the laboratory., Methods: The frequency of splashes from opening snap-cap tubes using four different methods was tested. The splash frequency for each method was measured on the benchtop surface and on the experimenter's gloves and smock, using a Glo Germ solution as a tracer., Results: Splashes occurred very frequently when opening microcentrifuge snap-cap tubes, no matter which method was used to open the tube. The highest rate of splashes on all surfaces was observed with the one-handed (OH) opening method compared with two-handed methods. Across all methods, the highest rate of splashes was observed on the opener's gloves (70-97%) compared with the benchtop (2-40%) or the body of the researcher (0-7%)., Conclusions: All tube opening methods we studied frequently caused splashes, with the OH method being the most error-prone but no two-handed method being clearly superior to any other. In addition to posing an exposure risk to laboratory personnel, experimental repeatability may be affected due to loss of volume when using snap-cap tubes. The rate of splashes underscores the importance of secondary containment, personal protective equipment, and good protocols for decontamination. When working with especially hazardous materials, alternatives to snap-cap tubes (such as screw cap tubes) should be strongly considered. Future studies can examine other methods of opening snap-cap tubes to determine whether a truly safe method exists., Competing Interests: No competing financial interests exist., (Copyright 2023, ABSA International 2023.)

This brief report introduces the Cancer Outcomes and Survivorship domain in the PhenX Toolkit (consensus measures for Phenotypes and eXposures), which includes 15 validated measurement protocols for cancer survivorship research that were recommended for inclusion in this publicly available resource. Developed with input from the scientific community, the domain provides researchers with well-established measurement protocols for evaluating physical and psychological effects, financial toxicity, and patient experiences with cancer care. The PhenX Toolkit, funded by the National Human Genome Research Institute since 2007, is an online resource that provides high-quality standard measurement protocols for a wide range of research areas (eg, smoking cessation, harm reduction and biomarkers, and social determinants of health). Use of the PhenX Cancer Survivorship Outcomes and Survivorship domain can simplify the selection of measurement protocols, data sharing, and comparisons across studies investigating the cancer survivorship experience., (© The Author(s) 2023.

Objective: We examined the social network support, composition, and structure of pediatric cancer caregivers., Methods: We used a self-report survey to collect egocentric social network data from 107 caregivers of pediatric cancer patients and calculated descriptive statistics to examine cancer-related support network composition, function, and structure. We then ran logistic regressions to examine the relationships between network characteristics and overall satisfaction with social support., Results: Family members were the most common source of emotional support and logistical support, and health care providers were the most common source of informational support. Participants perceived the "most helpful" forms of support as being: (1) emotional support from family and health care providers; (2) informational support from health care providers and other cancer caregivers; and (3) logistical support from family. Overall, caregivers wished that 9.8% of their network ties had provided more support, with family members being the most common alter type to disappoint caregivers and offer less support than needed/expected. Caregivers who reported higher network disappointment (having network members who offered less support than needed/expected) were significantly less satisfied with emotional support than those with lower network disappointment (Odds Ratio = 0.18, p = 0.02), and caregivers with higher network disappointment were significantly less satisfied with logistical support compared to those with lower network disappointment (Odds Ratio = 0.14, p = 0.01)., Conclusion: Our results show differences in the nature of social support provided by different types of network members. These findings have implications for tailoring social network interventions to improve caregiver and family outcomes., (© 2023 John Wiley & Sons Ltd.)

Introduction: Needle biopsy is essential for definitive diagnosis of breast malignancy. Significant histologic changes due to tissue damage have been reported in solid tumors. This study investigated the association between time from needle biopsy and inflammation in breast tumors., Methods: A total of 73 stage I-II invasive breast cancer cases diagnosed by image-guided needle biopsy who had surgery as their first definitive treatment were retrospectively analyzed. Time from biopsy to surgical excision ranged from 8 to 252 days. Histological sections of surgically resected tumors with a visible needle tract were reviewed by histologic evaluation. Data were analyzed by McNemar's test for proportional differences, and the Benjamini-Hochberg procedure was used to assess the association between immune cell prevalence and clinical variables., Results: Characteristic histology changes, including foreign body giant-cell reaction, synovial-cell metaplasia, desmoplastic repair changes, granulation tissue, fat necrosis, and inflammation, were frequently detected adjacent to the needle tract. Spatial comparison indicated that a higher proportion of cases had neutrophils, eosinophils, and macrophages adjacent to the needle tract than tumors distant from it. The presence of inflammatory cells adjacent to the needle tract was not associated with time from biopsy or subtype. Still, plasma cells were associated with residual carrier material from biopsy markers., Conclusion: Macrophages and eosinophils are highly abundant and retained adjacent to the needle tract regardless of time from the biopsy., (The Author(s).

Background: Systematically assessing disease risk can improve population health by identifying those eligible for enhanced prevention/screening strategies. This study aims to determine the clinical impact of a systematic risk assessment in diverse primary care populations., Methods: Hybrid implementation-effectiveness trial of a family health history-based health risk assessment (HRA) tied to risk-based guideline recommendations enrolling from 2014-2017 with 12 months of post-intervention survey data and 24 months of electronic medical record (EMR) data capture., Setting: 19 primary care clinics at four geographically and culturally diverse U.S. healthcare systems., Participants: any English or Spanish-speaking adult with an upcoming appointment at an enrolling clinic., Methods: A personal and family health history based HRA with integrated guideline-based clinical decision support (CDS) was completed by each participant prior to their appointment. Risk reports were provided to patients and providers to discuss at their clinical encounter., Outcomes: provider and patient discussion and provider uptake (i.e. ordering) and patient uptake (i.e. recommendation completion) of CDS recommendations., Measures: patient and provider surveys and EMR data., Results: One thousand eight hundred twenty nine participants (mean age 56.2 [SD13.9], 69.6% female) completed the HRA and had EMR data available for analysis. 762 (41.6%) received a recommendation (29.7% for genetic counseling (GC); 15.2% for enhanced breast/colon cancer screening). Those with recommendations frequently discussed disease risk with their provider (8.7%-38.2% varied by recommendation, p-values ≤ 0.004). In the GC subgroup, provider discussions increased referrals to counseling (44.4% with vs. 5.9% without, P < 0.001). Recommendation uptake was highest for colon cancer screening (provider = 67.9%; patient = 86.8%) and lowest for breast cancer chemoprevention (0%)., Conclusions: Systematic health risk assessment revealed that almost half the population were at increased disease risk based on guidelines. Risk identification resulted in shared discussions between participants and providers but variable clinical action uptake depending upon the recommendation. Understanding the barriers and facilitators to uptake by both patients and providers will be essential for optimizing HRA tools and achieving their promise of improving population health., Trial Registration: Clinicaltrials.gov number NCT01956773 , registered 10/8/2013., (© 2022.

Purpose: Smartphone-enabled micro-temporal data collection has potential to increase reliability, validity, and feasibility of participant-reported data and is a promising strategy for pediatric oncology supportive care and quality-of-life research. Given the demands of pediatric cancer caregiving, we sought to understand the feasibility and acceptability of smartphone data collection that included short surveys administered daily for 14 days via text message link., Methods: We recruited pediatric cancer caregivers, whose children (ages 0-18 years) were on active treatment, to complete a 14-day daily survey study via smartphone. We implemented our study procedures and examined feasibility through study enrollment rates, reasons for refusal, retention rates, number of reminders and number of completed surveys. We examined acceptability using caregiver ratings of survey length, burden, and ease of completion on a smartphone., Results: We recruited (N = 75) caregivers to the study and had an 84% enrollment rate. Reasons for declining participation included passive refusal (n = 13) and too busy (n = 1). The participant retention rate was 100% and compliance with daily survey completion was 99%. Most surveys were completed following two prompts and took participants 5 minutes or less to complete. Caregivers rated the surveys as easy to complete, low burden, and just right in length., Conclusion: A daily self-report, using a brief (≤5 minutes) survey administered on a smartphone via text message prompt, is a feasible and acceptable method. Future research should extend these findings to understand the generalizability across pediatric cancer caregiving contexts., (© 2022 Wiley Periodicals LLC.)

Culture and social structure are not separated analytical domains but intertwined phenomena observable in personal networks. Drawing on a personal networks dataset of migrants in the United States and Spain, we show that the country of origin, a proxy for diverse languages and cultural institutions, and religion may be predicted by specific combinations of personal network structural measures (closeness, clustering, betweenness, average degree, etc). We obtain similar results applying three different methods (a multinomial logistic regression, a Random Forest algorithm, and an artificial neural network). This finding is explained within the framework of the Grid/Group theory that has long posed the interdependence of social structural and cultural features of human groups., (© The Author(s) 2022.

Objective: The purpose of this quality improvement initiative was to evaluate satisfaction of family members of patients in a neuro trauma ICU (NTICU)., Methods: Adult patients (age 18+) admitted to the NTICU for at least 24 hours between June 2017 and November 2018 were identified. Near or at the time of discharge from the NTICU, the health unit coordinator or registered nurse identified the family member who was either the next-of-kin, surrogate decision-maker, or person who had been most frequently present at the patient's bedside. This person was provided a packet containing a letter of consent and the Critical Care Family Satisfaction Survey (CCFSS)., Results: Surveys were completed by 78 family members, the majority of whom were the wife of the patient (n = 35, 44%), 60 years and older (n = 48, 60.8%). Fifty-seven percent of patients (n = 45) were in the ICU less than 3 days and 59% (n = 47) of medical events were injury-related. Total CCFSS scores ranged from 69 to 100 (median 95). The item with the largest number of dissatisfied responses was "Noise level in the critical care unit" (n = 4, 5.3% not satisfied). Open-ended question comments were primarily positive (n = 60, 66%), with 32% (n = 29) representing areas for improvement., Conclusions: Results of this satisfaction survey have been disseminated to leadership and have been taken into consideration in the planning of a new hospital building currently being built, including ICU patient rooms that allow for more privacy and reduced noise, and more comfortable family rooms., Relevance to Clinical Practice: Family members are a very useful source of feedback for ICU care. Several concerns identified by family members in this study are likely to be relevant to other sites. These included: communication between health care providers and family about patient status, noise in the ICU, peaceful waiting areas for family, and slow transfers., (© 2020 British Association of Critical Care Nurses.)

Objectives: The World Health Organization estimates that almost 300 million people suffer from depression worldwide. African Americans are understudied for depression-related phenotypes despite widespread racial disparities. In our study of African Americans, we integrated information on psychosocial stressors with genetic variation in order to better understand how these factors associated with depressive symptoms., Methods: Our research strategy combined information on financial strain and social networks with genetic data to investigate variation in symptoms of depression (CES-D scores). We collected self-report data on depressive symptoms, financial strain (difficulty paying bills) and personal social networks (a model of an individual's social environment), and we genotyped genetic variants in five genes previously implicated in depressive disorders (HTR1a, BDNF, GNB3, SLC6A4, and FKBP5) in 128 African Americans residing in Tallahassee, Florida. We tested for direct and gene-environment interactive effects of the psychosocial stressors and genetic variants on depressive symptoms., Results: Significant associations were identified between high CES-D scores and a stressful social environment (i.e., a high percentage of people in participants' social network who were a source of stress) and high financial strain. Only one genetic variant (rs1360780 in FKBP5) was significantly associated with CES-D scores and only when psychosocial stressors were included in the model; the T allele had an additive effect on depressive symptoms. Sex was also significantly associated with CES-D score in the model with psychosocial stressors and genetic variants; males had higher CES-D scores. No significant interactive effects were detected., Conclusions: A stressful social environment and material disadvantage increase depressive symptoms in the study population. Additional associations with FKBP5 and male sex were revealed in models that included both psychosocial and genetic data. Our results suggest that incorporating psychosocial stressors may empower future genetic association studies and help clarify the biological consequences of social and financial stress., (© 2021 Wiley Periodicals LLC.)

Some research has raised the possibility that gamma linolenic acid (GLA) can increase resting metabolic rate (RMR), which can help with weight control. However, in overweight young adults with a family history of obesity, no effect on RMR was seen after a 6 weeks treatment with borage oil (880 mg GLA per day) or evening primrose oil (540 mg GLA per day). On the other hand, borage oil did lower plasma triglyceride readings and raise HDL cholesterol readings (mean starting values in normal range for triglycerides, borderline low for HDL). No effect was seen for body mass index, plasma total cholesterol, LDL cholesterol, or glucose. Thus, in the type of subjects studied here, borage oil, a source of GLA, did not show promise as a weight control aid, but could help prevent undesirable readings for two blood lipid measures.

This review examines the global literature concerning HIV/STI risk among trafficked female sex workers (FSWs), in relation to sex trafficking and drug use. The compound effects of sexual and drug-related risk merit a systematic literature review to grant a better understanding of their role in HIV/STI transmission. The current review synthesizes the results of 21 studies conducted in multiple cultural settings. Though the selected studies similarly found heightened HIV risks faced by trafficked FSWs, the focuses varied from the effect of trafficking on HIV, to the effect of entry age to sex work on HIV, to the effects of various forms of violence on HIV, to the effect of HIV risk behaviors on HIV, and to the relationship between HIV and other STIs. While focuses and findings varied, they are in consensus that various forms of violence and diminished autonomy, as a result of sex trafficking, accelerate the FSWs' risks of HIV/STIs even in comparison to women who voluntarily enter the sex trade. Variations in findings may be attributed to specific socio-cultural settings and various research methods as well as differences in the risk factors being studied. This points to the need for more empirical studies - particularly those that specifically target trafficked FSWs and the mechanisms of HIV/STI transmissions among the highly vulnerable population..

Background: Health risk behaviors are the most common sources of morbidity among adolescents. Adolescent health guidelines (Guidelines for Preventive Services by the AMA and Bright Futures by the Maternal Child Health Bureau) recommend screening and counseling, but the implementation is inconsistent., Objective: This study aims to test the efficacy of electronic risk behavior screening with integrated patient-facing feedback on the delivery of adolescent-reported clinician counseling and risk behaviors over time., Methods: This was a randomized controlled trial comparing an electronic tool to usual care in five pediatric clinics in the Pacific Northwest. A total of 300 participants aged 13-18 years who attended a well-care visit between September 30, 2016, and January 12, 2018, were included. Adolescents were randomized after consent by employing a 1:1 balanced age, sex, and clinic stratified schema with 150 adolescents in the intervention group and 150 in the control group. Intervention adolescents received electronic screening with integrated feedback, and the clinicians received a summary report of the results. Control adolescents received usual care. Outcomes, assessed via online survey methods, included adolescent-reported receipt of counseling during the visit (measured a day after the visit) and health risk behavior change (measured at 3 and 6 months after the visit)., Results: Of the original 300 participants, 94% (n=282), 94.3% (n=283), and 94.6% (n=284) completed follow-up surveys at 1 day, 3 months, and 6 months, respectively, with similar levels of attrition across study arms. The mean risk behavior score at baseline was 2.86 (SD 2.33) for intervention adolescents and 3.10 (SD 2.52) for control adolescents (score potential range 0-21). After adjusting for age, gender, and random effect of the clinic, intervention adolescents were 36% more likely to report having received counseling for endorsed risk behaviors than control adolescents (adjusted rate ratio 1.36, 95% CI 1.04 to 1.78) 1 day after the well-care visit. Both the intervention and control groups reported decreased risk behaviors at the 3- and 6-month follow-up assessments, with no significant group differences in risk behavior scores at either time point (3-month group difference: β=-.15, 95% CI -0.57 to -0.01, P=.05; 6-month group difference: β=-.12, 95% CI -0.29 to 0.52, P=.57)., Conclusions: Although electronic health screening with integrated feedback improves the delivery of counseling by clinicians, the impact on risk behaviors is modest and, in this study, not significantly different from usual care. More research is needed to identify effective strategies to reduce risk in the context of well-care., Trial Registration: ClinicalTrials.gov NCT02882919; https://clinicaltrials.gov/ct2/show/NCT02882919., (©Laura Richardson, Elizabeth Oshrin Parker, Chuan Zhou, Julie Kientz, Elizabeth Ozer, Carolyn McCarty.

Over the last century scientific research has become an increasingly collaborative endeavor. Commentators have pointed to different factors which contribute to this trend, including the specialization of science and growing need for diversity of interest and expertise areas in a scientific team. Very few studies, however, have precisely evaluated how the diversity of interest topics between researchers is related to the emergence of collaboration. Existing theoretical arguments suggest a curvilinear relationship between topic similarity and collaboration: too little similarity can complicate communication and agreement, yet too much overlap can increase competition and limit the potential for synergy. We test this idea using data on six years of publications across all disciplines at a large U.S. research university (approximately 14,300 articles, 12,500 collaborations, and 3,400 authors). Employing topic modelling and network statistical models, we analyze the relationship between topic overlap and the likelihood of coauthorship between two researchers while controlling for potential confounders. We find an inverted-U relationship in which the probability of collaboration initially increases with topic similarity, then rapidly declines after peaking at a similarity "sweet spot". Collaboration is most likely at low-to-moderate levels of topic overlap, which are substantially lower than the average self-similarity of scientists or research groups. These findings - which we replicate for different units of analysis (individuals and groups), genders of collaborators, disciplines, and collaboration types (intra- and interdisciplinary) - support the notion that researchers seek collaborators to augment their scientific and technical human capital. We discuss implications for theories of scientific collaboration and research policy.

Background: Risk assessment is a precision medicine technique that can be used to enhance population health when applied to prevention. Several barriers limit the uptake of risk assessment in health care systems; and little is known about the potential impact that adoption of systematic risk assessment for screening and prevention in the primary care population might have. Here we present results of a first of its kind multi-institutional study of a precision medicine tool for systematic risk assessment., Methods: We undertook an implementation-effectiveness trial of systematic risk assessment of primary care patients in 19 primary care clinics at four geographically and culturally diverse healthcare systems. All adult English or Spanish speaking patients were invited to enter personal and family health history data into MeTree, a patient-facing family health history driven risk assessment program, for 27 medical conditions. Risk assessment recommendations followed evidence-based guidelines for identifying and managing those at increased disease risk., Results: One thousand eight hundred eighty-nine participants completed MeTree, entering information on N = 25,967 individuals. Mean relatives entered = 13.7 (SD 7.9), range 7-74. N = 1443 (76.4%) participants received increased risk recommendations: 597 (31.6%) for monogenic hereditary conditions, 508 (26.9%) for familial-level risk, and 1056 (56.1%) for risk of a common chronic disease. There were 6617 recommendations given across the 1443 participants. In multivariate analysis, only the total number of relatives entered was significantly associated with receiving a recommendation., Conclusions: A significant percentage of the general primary care population meet criteria for more intensive risk management. In particular 46% for monogenic hereditary and familial level disease risk. Adopting strategies to facilitate systematic risk assessment in primary care could have a significant impact on populations within the U.S. and even beyond., Trial Registration: Clinicaltrials.gov number NCT01956773 , registered 10/8/2013.

Purpose of Review: Identity is one of the key domains that is disturbed in people manifesting personality disorder (PD). Within the field of personality psychology, there is a robust approach to studying identity focused on narrative identity which has been largely overlooked in studying PD. In this paper, a systematic review was conducted of studies published in the past decade that focused on how individuals manifesting personality pathology craft their narrative identity., Recent Findings: This review revealed disturbances related to several motivational/affective themes (e.g., negative valence/valence shifts and thwarted themes of agency and communion), autobiographical reasoning (negative self-inferences), and structural elements (e.g., low coherence and fewer life script events) within the narrative identity of people who manifest PD. Narrative identity is disturbed in people experiencing personality pathology and may have crucial implications for enhancing our conceptual understanding of PD and for PD interventions. This review also points to several research limitations and gaps that we encourage the field to pursue in the future.

This invited article is one of several comprising part of a special issue of Child Abuse and Neglect focused on child trafficking and health. The purpose of each invited article is to describe a specific program serving trafficked children. Featuring these programs is intended to raise awareness of innovative counter-trafficking strategies emerging worldwide and facilitate collaboration on program development and outcomes research. This article describes Project Intersect, a program of mental health services and behavioral health professional training designed to address trauma-related psychological and behavioral problems experienced by adolescent survivors of commercial sexual exploitation and trafficking. The project is led by the Georgia Center for Child Advocacy in Atlanta, GA, USA. The primary goal of the program is to build a cadre of behavioral health specialists with skills to implement trauma-focused cognitive behavioral therapy to address the unique needs of trafficked/exploited youth. This involves intensive initial training, follow-up consultation, technical support, and program evaluation., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Objective: Investigate sociodemographic differences in the use of a patient-facing family health history (FHH)-based risk assessment platform., Methods: In this large multisite trial with a diverse patient population, we evaluated the relationship between sociodemographic factors and FHH health risk assessment uptake using an information technology (IT) platform. The entire study was administered online, including consent, baseline survey, and risk assessment completion. We used multivariate logistic regression to model effect of sociodemographic factors on study progression. Quality of FHH data entered as defined as relatives: (1) with age of onset reported on relevant conditions; (2) if deceased, with cause of death and (3) age of death reported; and (4) percentage of relatives with medical history marked as unknown was analyzed using grouped logistic fixed effect regression., Results: A total of 2,514 participants consented with a mean age of 57 and 10.4% minority. Multivariate modeling showed that progression through study stages was more likely for younger ( p -value = 0.005), more educated ( p -value = 0.004), non-Asian ( p -value = 0.009), and female ( p -value = 0.005) participants. Those with lower health literacy or information-seeking confidence were also less likely to complete the study. Most significant drop-out occurred during the risk assessment completion phase. Overall, quality of FHH data entered was high with condition's age of onset reported 87.85%, relative's cause of death 85.55% and age of death 93.76%, and relative's medical history marked as unknown 19.75% of the time., Conclusion: A demographically diverse population was able to complete an IT-based risk assessment but there were differences in attrition by sociodemographic factors. More attention should be given to ensure end-user functionality of health IT and leverage electronic medical records to lessen patient burden., Competing Interests: Drs. Wu, Orlando, and Ginsburg and Mrs. Rakhra-Burris have a potential conflict of interest. They are cofounders of a company, MeTree&You that will provide MeTree as a clinical service. MeTree&You has not and will not receive any direct financial gain from this study or publication.

Research on women who engage both in drug use and sex work has been limited, as most previous studies have focused on these risk behaviors separately. The current study examines the network properties as well as the demographic and behavioral factors associated with drug use among female sex workers (FSWs) in southern China. We collected survey data (n = 175) in the Hainan province during our 26 months of ethnographic fieldwork in China. Our analyses included Fisher's exact chi-square tests, independent-samples t-tests, Mann-Whitney U, binary logistic regression (LR), as well as ethnographic data analysis. Multivariate analysis showed that women who were younger age, single, more educated, and earning a higher income were more likely to use drugs. Pertaining to network properties, FSWs with a lower percentage of long-term clients (and men) in ego networks were more likely to use drugs; this would imply a mechanism by which drug-using FSWs are more at risk, as the women take a greater number of transient clients. In addition, FSWs who were influential network members (i.e., higher betweenness centrality) and were closely related to other network members (i.e., higher closeness centrality) were more likely to use drugs; this may suggest that drug use is a means of sustaining the high functionality of the workers. Our ethnographic data also showed that club drug use was easily accessible in entertainment venues and was often a means of socialization in FSW communities. Network characteristics correlated to HIV-related risks among FSWs should be further examined in future studies.

Deaths due to hypertension in the US are highest among African Americans, who have a higher prevalence of hypertension and more severe hypertensive symptoms. Research indicates that there are both genetic and sociocultural risk factors for hypertension. Racial disparities in hypertension also likely involve genetic and sociocultural factors, but the factors may interact and manifest differently across racial groups. Here we use a biocultural approach to integrate genetic and social network data to better understand variation in blood pressure. We assay genetic variation at the angiotensin I converting enzyme gene (ACE) and analyze social network composition and structure in African Americans living in Tallahassee, FL (n = 138). We demonstrate that models including both genetic and social network data explain significantly more variation in blood pressure and have better model diagnostics than do models including only one datatype. Specifically, optimal models for systolic and diastolic blood pressure explain a notable 35% and 21%, respectively, of blood pressure variation. Analysis of the social networks reveals that individuals whose networks are dominated by family connections and are more fragmented have higher blood pressure. Historically, family support has been associated with better mental and physical health, but our results suggest that those family connections can also take a toll on health. These findings raise compelling questions regarding the roles of genetics, family, and social environment in hypertension in the African American community and suggest that interactions among these factors may help explain racial disparities in hypertension more accurately than any of the factors alone., Competing Interests: The authors have declared that no competing interests exist.

Androgen deprivation in men leads to increased adiposity, but the mechanisms underlying androgen regulation of fat mass have not been fully defined. Androgen receptor (AR) is expressed in monocytes/macrophages, which are resident in key metabolic tissues and influence energy metabolism in surrounding cells. Male mice bearing a cell-specific knockout of the AR in monocytes/macrophages (M-ARKO) were generated to determine whether selective loss of androgen signaling in these cells would lead to altered body composition. Wild-type (WT) and M-ARKO mice (12-22 weeks of age, n = 12 per group) were maintained on a regular chow diet for 8 weeks and then switched to a high-fat diet for 8 additional weeks. At baseline and on both the regular chow and high-fat diets, no differences in lean mass or fat mass were observed between groups. Consistent with the absence of differential body weight or adiposity, no differences in food intake (3.0 ± 0.5 g per day for WT mice vs 2.8 ± 0.4 g per day for M-ARKO mice) or total energy expenditure (0.6 ± 0.1 Kcal h -1 for WT mice vs 0.5 ± 0.1 Kcal h -1 for M-ARKO mice) were evident between groups during high-fat feeding. Liver weight was greater in M-ARKO than that in WT mice (1.5 ± 0.1 g vs 1.3 ± 0.0 g, respectively, P = 0.02). Finally, M-ARKO mice did not exhibit impairments in glucose tolerance or insulin sensitivity relative to WT mice at any study time point. In aggregate, these findings suggest that AR signaling specifically in monocytes/macrophages does not contribute to the regulation of systemic energy balance, adiposity, or insulin sensitivity in male mice.

Parental stress is an important risk factor for child maltreatment (CM) perpetration. Evidence-based, parent-training programs can decrease CM perpetration risk and reduce self-reported parental stress; however, little is known about how such programs impact physiological stress correlates. In this quasi-experimental pilot study, maternal biobehavioral responses were measured in response to SafeCare®, an evidence-based program targeting CM, often implemented by social workers in child welfare settings. Maternal participants (N = 18) were recruited to complete SafeCare and repeated within-subject assessments pre- and post-intervention. Analyses examined associations between self-reported parental stress and mental health symptomology with stress markers for cortisol, alpha-amylase, and dihydroepiandrosterone at baseline and follow-up. Baseline correlation analyses showed strong associations between parental stress, salivary cortisol levels, and alpha-amylase. At follow-up, significant correlations were found between parental stress and alpha-amylase for intervention completers (n = 7). Completers on average exhibited decreases across self-reported parental stress and global distress symptomology and improvements in salivary cortisol and alpha-amylase levels. Participants with impaired cortisol levels at baseline were within normal limits post-intervention. These pilot findings suggest that salivary cortisol and alpha-amylase are compelling physiological correlates of parental stress among high-risk parents. Results also support short-term, positive effects of SafeCare in potentially regulating physiological stress systems among at-risk mothers.

Objectives: The aims of the study were to estimate the prevalence of diabetic retinopathy (DR) and enumerate history-based risk factors in the urban slums of Western India., Methods: The population-based study was conducted in seven wards of Mumbai urban slums, where we screened 6569 subjects of ≥ 40 years age, with a response rate of 98.4%, for type 2 diabetes mellitus (T2DM) based on American Diabetes Association criteria. All subjects with T2DM underwent dilated 30° seven-field stereo-fundus-photography for DR severity grading based on modified Airlie House classification. A multivariate logistic regression model was used to assess the correlation of DR with the history-based risk factors., Results: The prevalence of DR in the general population of Mumbai urban slums was 1.41% (95% CI 0.59-2.23) and in the T2DM population it was 15.37% (95% CI 8.87-21.87). The positive associations with DR were the longer duration of DM (≥ 11 years: OR, 12.77; 95% CI 2.93-55.61) and male gender (OR, 2.05; 95% CI 1.08-3.89); increasing severity of retinopathy was also significantly associated with longer duration of DM (p < 0.001). However, history of hypertension, family history of DM, consanguineous marriage and migration status were not associated with DR in the study population., Conclusions: The prevalence of DR in the general population and T2DM subjects were 1.41% and 15.37% respectively in Mumbai urban slums. Duration of DM and male gender were significantly associated with DR. The slums in Western India show the trends of urban lifestyle influences similar to the rest of urban India.

A growing body of evidence shows that collaborative teams and communities tend to produce the highest-impact scientific work. This paper proposes a new method to (1) Identify collaborative communities in longitudinal scientific networks, and (2) Evaluate the impact of specific research institutes, services or policies on the interdisciplinary collaboration between these communities. First, we apply community-detection algorithms to cross-sectional scientific collaboration networks and analyze different types of co-membership in the resulting subgroups over time. This analysis summarizes large amounts of longitudinal network data to extract sets of research communities whose members have consistently collaborated or shared collaborators over time. Second, we construct networks of cross-community interactions and estimate Exponential Random Graph Models to predict the formation of interdisciplinary collaborations between different communities. The method is applied to longitudinal data on publication and grant collaborations at the University of Florida. Results show that similar institutional affiliation, spatial proximity, transitivity effects, and use of the same research services predict higher degree of interdisciplinary collaboration between research communities. Our application also illustrates how the identification of research communities in longitudinal data and the analysis of cross-community network formation can be used to measure the growth of interdisciplinary team science at a research university, and to evaluate its association with research policies, services or institutes.
