Insights into the clinical presentation, diagnostics and outcome in dogs presenting with neurological signs secondary to infection with Neospora caninum: 41 cases (2014-2023)

OBJECTIVES

To describe the clinical signs and outcome of a large cohort of dogs presenting with neurological signs secondary to Neospora caninum infection.

MATERIALS AND METHODS

Retrospective review of cases presenting to two UK referral centres with neurological signs secondary to N. caninum infection between 2014 and 2023. Presenting signs, diagnostic test results, treatment, short- and long-term outcome analysed.

RESULTS

A total of 1690 cases were assessed for eligibility. Forty-four cases with a diagnosis of neosporosis were obtained. Three cases were then excluded due to non-neurological presentations (two hepatitis and one myocarditis). A total of 41 cases were included in the study. Cerebello-vestibular signs predominated; however, presenting clinical signs were varied and the neurolocalisation was often multifocal in nature (46.3%), making neosporosis an important differential diagnosis for meningoencephalitis of unknown origin. Complete clinical improvement was rare (5.6%), and relapses were common (27.8% cases with follow-up).

CLINICAL SIGNIFICANCE

Neosporosis remains an important differential diagnosis for dogs at any age presenting with multifocal neurological signs. The outcome is considered poor and relapse rate is high.

Positive outcome reporting in orthopaedic literature

Aims

Perthes' disease (PD) is a relatively rare syndrome of idiopathic osteonecrosis of the proximal femoral epiphysis. Treatment for Perthes' disease is controversial due to the many options available, with no clear superiority of one treatment over another. Despite having few evidence-based approaches, many patients with Perthes' disease are managed surgically. Positive outcome reporting, defined as reporting a study variable producing statistically significant positive (beneficial) results, is a phenomenon that can be considered a proxy for the strength of science. This study aims to conduct a systematic literature review with the hypothesis that positive outcome reporting is frequent in studies on the treatment of Perthes' disease.

Methods

We conducted a systematic review of all available abstracts associated with manuscripts in English or with English translation between January 2000 and December 2021, dealing with the treatment of Perthes' disease. Data collection included various study characteristics, surgical versus non-surgical management, treatment modality, mean follow-up time, analysis methods, and clinical recommendations.

Results

Our study included 130 manuscripts. Overall, 110 (85%) reported positive (beneficial) results, three (2%) reported negative results, and 17 (13%) reported no significant difference. Despite only 10/130 studies (8%) having a testable hypothesis, 71 (55%) recommended the use of their studied treatment methods for the patients, five (4%) made recommendations against the use of the studied treatment modality, and 54 (42%) did not make any recommendations.

Conclusion

The overall rate for positive outcomes among included manuscripts regarding different treatment methods for Perthes' disease (85%) is higher than the 74% positive outcome rate found among studies for other surgically treated disorders and significantly higher than most scientific literature. Despite the lack of testable hypotheses, most manuscripts recommended their studied treatment method as a successful option for managing patients solely based on the reporting of retrospective data.

Ticagrelor inverse agonist activity at the P2Y12 receptor is non-reversible versus its endogenous agonist adenosine 5´-diphosphate

BACKGROUND AND PURPOSE

Ticagrelor is labelled as a reversible, direct-acting platelet P2Y12 receptor (P2Y12 R) antagonist that is indicated clinically for the prevention of thrombotic events in patients with acute coronary syndrome (ACS). As with many antiplatelet drugs, ticagrelor therapy increases bleeding risk in patients, which may require platelet transfusion in emergency situations. The aim of this study was to further examine the reversibility of ticagrelor at the P2Y12 R.

EXPERIMENTAL APPROACH

Studies were performed in human platelets, with P2Y12 R-stimulated GTPase activity and platelet aggregation assessed. Cell-based bioluminescence resonance energy transfer (BRET) assays were undertaken to assess G protein-subunit activation downstream of P2Y12 R activation.

KEY RESULTS

Initial studies revealed that a range of P2Y12 R ligands, including ticagrelor, displayed inverse agonist activity at P2Y12 R. Only ticagrelor was resistant to washout and, in human platelet and cell-based assays, washing failed to reverse ticagrelor-dependent inhibition of ADP-stimulated P2Y12 R function. The P2Y12 R agonist 2MeSADP, which was also resistant to washout, was able to effectively compete with ticagrelor. In silico docking revealed that ticagrelor and 2MeSADP penetrated more deeply into the orthosteric binding pocket of the P2Y12 R than other P2Y12 R ligands.

CONCLUSION AND IMPLICATIONS

Ticagrelor binding to P2Y12 R is prolonged and more akin to that of an irreversible antagonist, especially versus the endogenous P2Y12 R agonist ADP. This study highlights the potential clinical need for novel ticagrelor reversal strategies in patients with spontaneous major bleeding, and for bleeding associated with urgent invasive procedures.

Methods for retrospectively improving race/ethnicity data quality: a scoping review

Improving race and ethnicity (hereafter, race/ethnicity) data quality is imperative to ensure underserved populations are represented in data sets used to identify health disparities and inform health care policy. We performed a scoping review of methods that retrospectively improve race/ethnicity classification in secondary data sets. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, searches were conducted in the MEDLINE, Embase, and Web of Science Core Collection databases in July 2022. A total of 2 441 abstracts were dually screened, 453 full-text articles were reviewed, and 120 articles were included. Study characteristics were extracted and described in a narrative analysis. Six main method types for improving race/ethnicity data were identified: expert review (n = 9; 8%), name lists (n = 27, 23%), name algorithms (n = 55, 46%), machine learning (n = 14, 12%), data linkage (n = 9, 8%), and other (n = 6, 5%). The main racial/ethnic groups targeted for classification were Asian (n = 56, 47%) and White (n = 51, 43%). Some form of validation evaluation was included in 86 articles (72%). We discuss the strengths and limitations of different method types and potential harms of identified methods. Innovative methods are needed to better identify racial/ethnic subgroups and further validation studies. Accurately collecting and reporting disaggregated data by race/ethnicity are critical to address the systematic missingness of relevant demographic data that can erroneously guide policymaking and hinder the effectiveness of health care practices and intervention.

Adeno-associated virus gene therapy prevents progression of kidney disease in genetic models of nephrotic syndrome

Gene therapy for kidney diseases has proven challenging. Adeno-associated virus (AAV) is used as a vector for gene therapy targeting other organs, with particular success demonstrated in monogenic diseases. We aimed to establish gene therapy for the kidney by targeting a monogenic disease of the kidney podocyte. The most common cause of childhood genetic nephrotic syndrome is mutations in the podocyte gene NPHS2, encoding podocin. We used AAV-based gene therapy to rescue this genetic defect in human and mouse models of disease. In vitro transduction studies identified the AAV-LK03 serotype as a highly efficient transducer of human podocytes. AAV-LK03-mediated transduction of podocin in mutant human podocytes resulted in functional rescue in vitro, and AAV 2/9-mediated gene transfer in both the inducible podocin knockout and knock-in mouse models resulted in successful amelioration of kidney disease. A prophylactic approach of AAV 2/9 gene transfer before induction of disease in conditional knockout mice demonstrated improvements in albuminuria, plasma creatinine, plasma urea, plasma cholesterol, histological changes, and long-term survival. A therapeutic approach of AAV 2/9 gene transfer 2 weeks after disease induction in proteinuric conditional knock-in mice demonstrated improvement in urinary albuminuria at days 42 and 56 after disease induction, with corresponding improvements in plasma albumin. Therefore, we have demonstrated successful AAV-mediated gene rescue in a monogenic renal disease and established the podocyte as a tractable target for gene therapy approaches.

Non-Partner Sexual Violence Among Asian American, Native Hawaiian, and Pacific Islander Adults: A Scoping Review

The Asian American, Native Hawaiian, and Pacific Islander (AANHPI) population is rapidly growing in the United States. Despite sexual violence being a persistent and significant public health issue, research on this topic among AANHPIs is lacking. The study objective is to conduct a systematic scoping review on the published literature on non-partner sexual violence among AANHPIs to identify gaps and priorities to inform actionable research. The systematic review was conducted following the PRISMA Protocol for Systematic Reviews. Database searches were conducted of MEDLINE, Embase, PsycINFO, and Cochrane Central of Clinical Trials, along with and AgeLine and CINAHL for peer-reviewed articles describing non-partner sexual violence among AANHPIs. The search was limited to articles in English published after 1990. Each citation was reviewed by two trained independent reviewers, with a third researcher resolving any conflicts. Of the 998 articles screened and subsequently 496 full-text articles assessed for eligibility, 38 articles were included in the final analysis. The majority of studies did not report disaggregated data for AANHPI subgroups, with most focusing on East Asian subgroups and little evidence on NHPI communities. Most studies were cross-sectional, quantitative, and employed non-probability sampling. There was a lack of studies on effectiveness of interventions and validity of sexual violence-related measures. Our review provides a first step in mapping the extant literature on non-partner sexual violence among this underserved and under-researched population and will serve as a guide for future research, policy, and intervention.

Challenges and Recommendations to Improve Institutional Review Boards’ Review of Community Engaged Research Proposals: A Scoping Review

Academic and community investigators conducting community-engaged research (CEnR) are often met with challenges when seeking Institutional Review Board (IRB) approval. This scoping review aims to identify challenges and recommendations for CEnR investigators and community partners working with IRBs. Peer-reviewed articles that reported on CEnR, specified study-related challenges, and lessons learned for working with IRBs and conducted in the United States were included for review. Fifteen studies met the criteria and were extracted for this review. Four challenges identified (1) Community partners not being recognized as research partners (2) Cultural competence, language of consent forms, and literacy level of partners; (3) IRBs apply formulaic approaches to CEnR; & (4) Extensive delays in IRB preparation and approval potentially stifle the relationships with community partners. Recommendations included (1) Training IRBs to understand CEnR principles to streamline and increase the flexibility of the IRB review process; (2) Identifying influential community stakeholders who can provide support for the study; and (3) Disseminating human subjects research training that is accessible to all community investigator to satisfy IRB concerns. Findings from our study suggest that IRBs can benefit from more training in CEnR requirements and methodologies.

Conservation Practices for Personal Protective Equipment: A Systematic Review with Focus on Lower-Income Countries

During the start of the COVID-19 pandemic, shortages of personal protective equipment (PPE) necessitated unprecedented and non-validated approaches to conserve PPE at healthcare facilities, especially in high income countries where single-use disposable PPE was ubiquitous. Our team conducted a systematic literature review to evaluate historic approaches for conserving single-use PPE, expecting that lower-income countries or developing contexts may already be uniquely conserving PPE. However, of the 50 included studies, only 3 originated from middle-income countries and none originated from low-income countries. Data from the included studies suggest PPE remained effective with extended use and with multiple or repeated use in clinical settings, as long as donning and doffing were performed in a standard manner. Multiple decontamination techniques were effective in disinfecting single use PPE for repeated use. These findings can inform healthcare facilities and providers in establishing protocols for safe conservation of PPE supplies and updating existing protocols to improve sustainability and overall resilience. Future studies should evaluate conservation practices in low-resource settings during non-pandemic times to develop strategies for more sustainable and resilient healthcare worldwide.

Waste audits in healthcare: A systematic review and description of best practices

Healthcare generates large amounts of waste, harming both environmental and human health. Waste audits are the standard method for measuring and characterizing waste. This is a systematic review of healthcare waste audits, describing their methods and informing more standardized auditing and reporting. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched MEDLINE, Embase, Inspec, Scopus and Web of Science Core Collection databases for published studies involving direct measurement of waste in medical facilities. We screened 2398 studies, identifying 156 studies for inclusion from 37 countries. Most were conducted to improve local waste sorting policies or practices, with fewer to inform policy development, increase waste diversion or reduce costs. Measurement was quantified mostly by weighing waste, with many also counting items or using interviews or surveys to compile data. Studies spanned single procedures, departments and hospitals, and multiple hospitals or health systems. Waste categories varied, with most including municipal solid waste or biohazardous waste, and others including sharps, recycling and other wastes. There were significant differences in methods and results between high- and low-income countries. The number of healthcare waste audits published has been increasing, with variable quality and general methodologic inconsistency. A greater emphasis on consistent performance and reporting standards would improve the quality, comparability and usefulness of healthcare waste audits.

Opioid Use Disorder Treatments: An Evidence Map

BACKGROUND

Evidence maps are emerging data visualization of a systematic review. There are no published evidence maps summarizing opioid use disorder (OUD) interventions.

AIM

Our aim was to publish an interactive summary of all peer-reviewed interventional and observational trials assessing the treatment of OUD and common clinical outcomes.

METHODS

PubMed, Embase, PsycInfo, Cochrane Central Register of Clinical Trials, and Web of Science were queried using multiple OUD-related MESH terms, without date limitations, for English-language publications. Inclusions were human subjects, treatment of OUD, OUD patient or community-level outcomes, and systematic reviews of OUD interventions. Exclusions were laboratory studies, reviews, and case reports. Two reviewers independently scanned abstracts for inclusion before coding eligible full-text articles by pre-specified filters: research design, study population, study setting, intervention, outcomes, sample size, study duration, geographical region, and funding sources.

RESULTS

The OUD Evidence Map (https://med.nyu.edu/research/lee-lab/research/opioid-use-disorder-treatment-evidence-map) identified and assessed 12,933 relevant abstracts through 2020. We excluded 9455 abstracts and full text reviewed 2839 manuscripts; 888 were excluded, 1591 were included in the final evidence map. The most studied OUD interventions were methadone (n = 754 studies), buprenorphine (n = 499), and naltrexone (n = 134). The most common outcomes were heroin/opioid use (n = 708), treatment retention (n = 557), and non-opioid drug use (n = 368). Clear gaps included a wider array of opioid agonists for treatment, digital behavioral interventions, studies of OUD treatments in criminal justice settings, and overdose as a clinical outcome.

CONCLUSION

This OUD Evidence Map highlights the importance of pharmacologic interventions for OUD and reductions in opioid use. Future iterations will update results annually and scan policy-level interventions.

Strategies to Improve Medication Adherence and Blood Pressure Among Racial/Ethnic Minority Populations: A Scoping Review of the Literature from 2017 to 2021

PURPOSE OF REVIEW

To identify intervention strategies that were effective in promoting medication adherence and HTN control among racial/ethnic minority groups in the US.

RECENT FINDINGS

Twelve articles were included in this review and 4 categories of intervention strategies were identified as counseling by trained personnel, mHealth tools, mHealth tools in combination with counseling by trained personnel, and quality improvement. The findings show that interventions delivered by trained personnel are effective in lowering BP and improving medication adherence, particularly for those delivered by health educators, CHWs, medical assistants, and pharmacists. Additionally, the combination of mHealth tools with counseling by trained personnel has the potential to be more effective than either mHealth or counseling alone and report beneficial effects on medication adherence and BP control. This review provides potential next steps for future research to examine the effectiveness of mHealth interventions in combination with support from trained health personnel and its effects on racial disparities in HTN outcomes.

Mask Use for Athletes: A Systematic Review of Safety and Performance Outcomes

CONTEXT

With the current Centers for Disease Control and Prevention recommendations for mask use to minimize transmission of coronavirus 2019 (COVID-19) coupled with concern for future pandemics that would require mask wearing, providing data-driven guidance with respect to athletic performance is essential.

OBJECTIVE

The purpose of this study was to perform a systematic review of existing literature on the use of face masks while exercising to assess the physiologic effects of face masks worn during athletic activities.

DATA SOURCES

A systematic review was conducted of studies on face mask use during exercise according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Potential studies were identified through searches of MEDLINE, Embase, Cochrane CENTRAL and CINAHL databases.

STUDY SELECTION

Screening was completed independently by 2 coauthors who sought to identify studies that described the effects of oronasal mask use, if any, on sports/exercise/physical activity, for any age, gender, or level of sport. Articles describing mask effects without exercise, articles published before 1980, and non-English language studies were excluded.

STUDY DESIGN

Systematic review.

LEVEL OF EVIDENCE

Level 3.

DATA EXTRACTION

Data extraction focused on physiologic parameters measured during physical activity performed while wearing a face mask.

RESULTS

Twenty-two articles met all inclusion criteria. Study analysis revealed that the use of masks in healthy volunteers during exercise had no significant effect on physiologic parameters measured including heart rate (HR), respiratory rate (RR), oxygen saturation, and perceived exertion. Of the studies that investigated N95 masks in the healthy adult population, 2 reported modest changes in RR and maximum power output indicative of decreased athletic performance when subjects were exercising at maximum effort. Similar findings were seen in studies of subpopulations including children and pregnant women.

CONCLUSION

Available data suggest that healthy individuals can perform moderate-to-vigorous exercise while wearing a face mask without experiencing changes in HR, RR, and oxygen saturation that would compromise individual safety or athletic performance. In the specific situation in which an N95 mask is worn, maximum power generated may be impaired.

WHAT IS KNOWN ABOUT THE SUBJECT

To date, there has been no systematic review of the existing literature to provide a clear consensus on whether face mask use significantly impacts athletic performance. Mask use has been demonstrated safe in the workplace; however, the use of face masks during exercise has not been examined on a large scale, particularly with respect to physiologic parameters.

WHAT THIS STUDY ADDS TO EXISTING KNOWLEDGE

This analysis highlights that available data suggest that healthy individuals can perform heavy exercise in face masks with minimal physiologic changes. This is the first systematic review of studies analyzing exercise use wearing masks. With the evidence presented here commonly cited concerns about both safety and performance decrements with mask use during physical activities may be allayed.

Are Screening Tools for Identifying Human Trafficking Victims in Health Care Settings Validated? A Scoping Review

OBJECTIVE

Although many screening tools, resources, and programs for identifying victims of human trafficking exist, consensus is lacking on which tools are most useful, which have been validated, and whether they are effective. The objectives of this study were to determine what tools exist to identify or screen for victims of human trafficking in health care settings and whether these tools have been validated.

METHOD

We conducted a scoping review of the literature on human trafficking identification in health care settings following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) protocol for scoping reviews. We searched the MEDLINE, PsycInfo, Embase, and Scopus databases without language or date limitations. Two independent reviewers screened each citation. We included human research studies in English with populations of all ages, all genders, all geographic locations, and using quantitative and/or qualitative research methods. We excluded studies that were not conducted in a health care setting, review articles, and meta-analyses. We summarized additional screening tools available online and identified through hand-searching.

RESULTS

Database searches yielded 8730 studies, of which 4806 remained after removing duplicates. We excluded 4720 articles based on title/abstract review, we reviewed 85 full-text studies for eligibility, and we included 8 articles. Hand-searching revealed 9 additional screening tools not found in the literature. Through our search for validated screening tools, only 6 had been studied for validation in health care settings.

CONCLUSIONS

Few studies have evaluated screening tools for identifying victims of human trafficking in health care settings. The absence of a gold standard for human trafficking screening and lack of consensus on the definition of human trafficking make screening tool validation difficult. Further research is required for the development of safe, effective approaches to patient screening.

Portable air cleaner use and biomarkers of inflammation: A systematic review and meta-analysis

Fine particulate matter air pollution (PM2.5) is a major contributor to cardiovascular morbidity and mortality, potentially via increased inflammation. PM2.5 exposure increases inflammatory biomarkers linked to cardiovascular disease, including CRP, IL-6 and TNFα. Portable air cleaners (PACs) reduce individual PM2.5 exposure but evidence is limited regarding whether PACs also reduce inflammatory biomarkers. We performed a systematic review and meta-analysis of trials evaluating the use of PACs to reduce PM2.5 exposure and inflammatory biomarker concentrations. We identified English-language articles of randomized sham-controlled trials evaluating high efficiency particulate air filters in non-smoking, residential settings measuring serum CRP, IL-6 and TNFα before and after active versus sham filtration, and performed meta-analysis on the extracted modeled percent change in biomarker concentration across studies. Of 487 articles identified, we analyzed 14 studies enrolling 778 participants that met inclusion criteria. These studies showed PACs reduced PM2.5 by 61.5 % on average. Of the 14 included studies, 10 reported CRP concentrations in 570 participants; these showed active PAC use was associated with 7 % lower CRP (95 % CI: -14 % to 0.0 %, p = 0.05). Nine studies of IL-6, with 379 participants, showed active PAC use was associated with 13 % lower IL-6 (95 % CI: [-23 %, -3 %], p = 0.009). Six studies, with 269 participants, reported TNF-α and demonstrated no statistical evidence of difference between active and sham PAC use. Portable air cleaners that reduce PM2.5 exposure can decrease concentrations of inflammatory biomarkers associated with cardiovascular disease. Additional studies are needed to evaluate clinical outcomes and other biomarkers.

Weight Status, Medication Use, and Recreational Activities of Treatment-Naïve Transgender Youth

Background: Studies of transgender/gender diverse (TGD) youth indicate a high prevalence of overweight/obesity and concern for unhealthy weight management behavior. This study describes the association of weight status with medication use and recreational activities among treatment-naïve, pediatric TGD patients. Methods: This study is a chart review of 277 patients [aged 9-18 years, 79.1% female sex assigned at birth (SAB), and 86.3% white] seen at a medical center from 2017 to 2020. BMI was calculated by age and SAB using CDC growth charts. BMI percentile (BMI%) and BMI z-score (BMIz) were used to define weight status. Results: By BMI% category, 3.6% patients were in the underweight range (BMI <5%); 50.5% had BMI >85%; and 30.3% had BMI >95%. Overweight and obesity rates were higher than national norms (χ² = 15.152, p < 0.01). Female SAB participants had higher BMIz values than male SAB participants. Youth who reported watching/listening to media (t = 3.50, p < 0.01) and parent-reported creative arts involvement (t = 1.97, p = 0.05) were associated with higher BMIz values. Conversely, spending time with friends and family was associated with a lower BMIz. Over half of the patients were prescribed medications, and those patients taking medications had higher BMIz values than those not taking medications (t = -1.96, p < 0.05). Female SAB, involvement in sedentary recreational activities, and taking medications to treat gastrointestinal conditions were associated with elevated BMIz. Conclusions: Overweight/obesity is a common problem among TGD youth. TGD youth should be considered a high-risk group and targeted in obesity prevention and treatment efforts. Interventions to decrease sedentary activities and improve connections with friends and family are promising strategies to address overweight and obesity among TGD youth.

Assessing Equitable Inclusion of Underrepresented Older Adults in Alzheimer's Disease, Related Cognitive Disorders, and Aging-Related Research: A Scoping Review

BACKGROUND AND OBJECTIVES

The rapidly aging and diversifying U.S. population is challenged by increases in prevalence of Alzheimer's disease (AD) and aging-related disorders. We conducted a scoping review to assess equitable inclusion of diverse older adult populations in aging research focused on National Institutes of Health (NIH)-sponsored research.

RESEARCH DESIGN AND METHODS

The scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-Scr) Protocol. The search was limited to NIH-funded studies focusing on aging, AD and Alzheimer's disease-related dementias (ADRD) and included adults aged 55+. The priority populations and health disparities put forth by the NIA Health Disparities Framework serve as a model for guiding inclusion criteria and for interpreting the representation of these underrepresented groups, including racial ethnic minorities, socioeconomically disadvantaged, rural populations, groups with disabilities, and LGBTQ communities.

RESULTS

Our search identified 1,177 records, of which 436 articles were included in the analysis. Inclusion of individuals with ADRD and mild cognitive impairment, racial ethnic minorities, rural populations, socioeconomically disadvantaged, groups with disabilities, and LGBTQ communities were poorly specified in most studies. Studies used multiple recruitment methods, conducting studies in community settings (59%) and hospitals/clinics (38%) most frequently. Incentives, convenience factors, and sustained engagement via community-based and care partners were identified as key strategies for improved retention.

DISCUSSION AND IMPLICATIONS

This scoping review identified gaps in existing literature and aims for future work, including stronger research focus on, better inclusion of, and improved data collection and reporting of older adults from underrepresented groups.

Chinese Americans' Use of Patient Portal Systems: Scoping Review

Background

Electronic patient portals are increasingly used in health care systems as communication and information-sharing tools and show promise in addressing health care access, quality, and outcomes. However, limited research exists on portal use patterns and practices among diverse patient populations, resulting in the lack of culturally and contextually tailored portal systems for these patients.

Objective

This study aimed to summarize existing evidence on the access and use patterns, barriers, and facilitators of patient portals among Chinese Americans, who represent a growing patient population in the United States with unique health care and health technology needs.

Methods

The authors conducted a literature search using the PRISMA Protocol for Scoping Reviews (Preferred Reporting Items for Systematic Reviews and Meta-Analyses-ScR) for extracting articles published in major databases (MEDLINE, Embase, and PsycINFO) on patient portals and Chinese Americans. Authors independently reviewed the papers during initial screening and full-text review. The studies were analyzed and coded for the study method type, sample population, and main outcomes of interest.

Results

In total, 17 articles were selected for inclusion in the review. The included articles were heterogenous and varied in their study aims, methodologies, sample populations, and outcomes. Major findings identified from the articles include variable patterns of portal access and use among Chinese Americans compared to other racial or ethnic groups, with limited evidence on the specific barriers and facilitators for this group; a preference for cross-sectional quantitative tools such as patient surveys and electronic health record–based data over qualitative or other methodologies; and a pattern of aggregating Chinese American–related data into a larger Asian or Asian American designation.

Conclusions

There is limited research evaluating the use patterns, experiences, and needs of Chinese Americans who access and use patient portal systems. Existing research is heterogeneous, largely cross-sectional, and does not disaggregate Chinese Americans from larger Asian demographics. Future research should be devoted to the specific portal use patterns, preferences, and needs of Chinese Americans to help ensure contextually appropriate and acceptable design and implementation of these digital health tools.

Incidence of dysphagia following posterior cervical spine surgery

Abundant literature exists describing the incidence of dysphagia following anterior cervical surgery; however, there is a paucity of literature detailing the incidence of dysphagia following posterior cervical procedures. Further characterization of this complication is important for guiding clinical prevention and management. Patients ≥ 18 years of age underwent posterior cervical fusion with laminectomy or laminoplasty between C1-T1. Pre- and post-operative dysphagia was assessed by a speech language pathologist. The patient cohort was categorized by approach: Laminectomy + Fusion (LF) and Laminoplasty (LP). Patients were excluded from radiographic analyses if they did not have both baseline and follow-up imaging. The study included 147 LF and 47 LP cases. There were no differences in baseline demographics. There were three patients with new-onset dysphagia in the LF group (1.5% incidence) and no new cases in the LP group (p = 1.000). LF patients had significantly higher rates of post-op complications (27.9% LF vs. 8.5% LP, p = 0.005) but not intra-op complications (6.1% LF vs. 2.1% LP, p = 0.456). Radiographic analysis of the entire cohort showed no significant changes in cervical lordosis, cSVA, or T1 slope. Both group comparisons showed no differences in incidence of dysphagia pre and post operatively. Based on this study, the likelihood of developing dysphagia after LF or LP are similarly low with a new onset dysphagia rate of 1.5%.

Dietary Transitions and Health Outcomes in Four Populations - Systematic Review

IMPORTANCE

Non-communicable chronic diseases (NCDs) such as obesity, type 2 diabetes, heart disease, and cancer were rare among non-western populations with traditional diets and lifestyles. As populations transitioned toward industrialized diets and lifestyles, NCDs developed.

OBJECTIVE

We performed a systematic literature review to examine the effects of diet and lifestyle transitions on NCDs.

EVIDENCE REVIEW

We identified 22 populations that underwent a nutrition transition, eleven of which had sufficient data. Of these, we chose four populations with diverse geographies, diets and lifestyles who underwent a dietary and lifestyle transition and explored the relationship between dietary changes and health outcomes. We excluded populations with features overlapping with selected populations or with complicating factors such as inadequate data, subgroups, and different study methodologies over different periods. The selected populations were Yemenite Jews, Tokelauans, Tanushimaru Japanese, and Maasai. We also review transition data from seven excluded populations (Pima, Navajo, Aboriginal Australians, South African Natal Indians and Zulu speakers, Inuit, and Hadza) to assess for bias.

FINDINGS

The three groups that replaced saturated fats (SFA) from animal (Yemenite Jews, Maasai) or plants (Tokelau) with refined carbohydrates had negative health outcomes (e.g., increased obesity, diabetes, heart disease). Yemenites reduced SFA consumption by >40% post-transition but men's BMI increased 19% and diabetes increased ~40-fold. Tokelauans reduced fat, dramatically reduced SFA, and increased sugar intake: obesity and diabetes rose. The Tanushimaruans transitioned to more fats and less carbohydrates and used more anti-hypertensive medications; stroke and breast cancer declined while heart disease was stable. The Maasai transitioned to lower fat, SFA and higher carbohydrates and had increased BMI and diabetes. Similar patterns were observed in the seven other populations.

CONCLUSION

The nutrient category most strongly associated with negative health outcomes - especially obesity and diabetes - was sugar (increased 600-650% in Yemenite Jews and Tokelauans) and refined carbohydrates (among Maasai, total carbohydrates increased 39% in men and 362% in women), while increased calories was less strongly associated with these disorders. Across 11 populations, NCDs were associated with increased refined carbohydrates more than increased calories, reduced activity or other factors, but cannot be attributed to SFA or total fat consumption.

United States Dietary Trends Since 1800: Lack of Association Between Saturated Fatty Acid Consumption and Non-communicable Diseases

We reviewed data on the American diet from 1800 to 2019. Methods: We examined food availability and estimated consumption data from 1800 to 2019 using historical sources from the federal government and additional public data sources. Results: Processed and ultra-processed foods increased from <5 to >60% of foods. Large increases occurred for sugar, white and whole wheat flour, rice, poultry, eggs, vegetable oils, dairy products, and fresh vegetables. Saturated fats from animal sources declined while polyunsaturated fats from vegetable oils rose. Non-communicable diseases (NCDs) rose over the twentieth century in parallel with increased consumption of processed foods, including sugar, refined flour and rice, and vegetable oils. Saturated fats from animal sources were inversely correlated with the prevalence of NCDs. Conclusions: As observed from the food availability data, processed and ultra-processed foods dramatically increased over the past two centuries, especially sugar, white flour, white rice, vegetable oils, and ready-to-eat meals. These changes paralleled the rising incidence of NCDs, while animal fat consumption was inversely correlated.

Engaging Underrepresented Older Adults in ADRD and Aging Research: A Scoping Review

The rapidly aging and diversifying U.S. population coincides with increases in prevalence of Alzheimer’s disease and related dementias (ADRD) and other aging-related disorders. Unfortunately, older adults and racial and ethnic minorities are often underrepresented in research studies. The differing barriers that underrepresented older adults face in research engagement indicate that results from studies conducted on younger and majority populations may not maintain external validity outside of those groups. Therefore, efforts to engage diverse older adults in research is imperative. The goal of this scoping review was to summarize findings of the current state of National Institute on Aging (NIA) sponsored research, identifying extant literature on engaging diverse older adult populations in aging and ADRD research. Among 566 articles screened for inclusion, 436 were included in the final analysis. Results showed that African Americans were represented in over half the studies (63.5%), but Native Hawaiian/Pacific Islander and American Indian or Alaska Native populations were not well represented. Community- and convenience-based recruitment and retention strategies that have demonstrated prior success in research engagement were widely utilized. Racial, ethnic, and income status breakdowns were not included in 30.0%, 57.1%, and 53.4% of studies respectively, making it difficult to assess the applicability of findings for particular groups. Inclusion of Alzheimer’s disease patients or those with mild cognitive impairments was also poorly defined in most studies. Findings highlight gaps in existing literature that can be used to inform future research, and recruitment and retention strategies for engaging racial and ethnic minority older adults in research.

Alzheimer's Disease Screening Tools for Asian Americans: A Scoping Review

With growing numbers of aging Asian Americans, Native Hawaiians, and Pacific Islanders (AANHPIs), the availability of culturally and linguistically appropriate screening tools for Alzheimer's disease and its related dementias (ADRD) is needed. The aim of this scoping review is to summarize the tools that have been adapted for and validated among the AANHPI population. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol for systematic reviews, six databases were searched for peer-reviewed articles describing ADRD among AANHPIs. Among 1,477 articles screened for inclusion, 15 articles were included in the final analysis. Results showed a paucity of studies that psychometrically validate tools among this population. Furthermore, studies that culturally adapted and/or translated existing tools mostly targeted East Asian American populations. Our review provides a first step in mapping the extant literature on ADRD screening tools for this underresearched population and will serve as a guide for future research, policy, and intervention.

Neuroscience Education as Therapy for Migraine and Overlapping Pain Conditions: A Scoping Review

BACKGROUND

Neuroscience Education Therapy (NET) has been successfully used for numerous overlapping pain conditions, but few studies have investigated NET for migraine.

OBJECTIVE

We sought to (1) review the literature on NET used for the treatment of various pain conditions to assess how NET has been studied thus far and (2) recommend considerations for future research of NET for the treatment of migraine.

DESIGN/METHODS

Following the PRISMA guideline for scoping reviews (PRISMA-ScR) Co-author (TR), a Medical Librarian, searched the MEDLINE, PsychInfo, Embase & Cochrane Central Clinical Trials Registry databases for peer-reviewed articles describing NET to treat migraine and other chronic pain conditions. Each citation was reviewed by two trained independent reviewers. Conflicts were resolved through consensus.

RESULTS

Overall, a NET curriculum consists of the following topics: pain does not equate to injury, pain is generated in the brain, perception, genetics, reward systems, fear, brain plasticity, and placebo/nocebo effects. Delivered through individual, group, or a combination of individual and group sessions, NET treatments often incorporate exercise programs and/or components of other evidence-based behavioral treatments. NET has significantly reduced catastrophizing, kinesiophobia, pain intensity, and disability in overlapping pain conditions. In migraine-specific studies, when implemented together with traditional pharmacological treatments, NET has emerged as a promising therapy by reducing migraine days, pain intensity and duration, and acute medication intake.

CONCLUSION

NET is an established treatment for pain conditions, and future research should focus on refining NET for migraine, examining delivery modality, dosage, components of other behavioral therapies to integrate, and migraine-specific NET curricula.

IGFBP-1 expression is reduced in human type 2 diabetic glomeruli and modulates β1-integrin/FAK signalling in human podocytes

AIMS/HYPOTHESIS

Podocyte loss or injury is one of the earliest features observed in the pathogenesis of diabetic kidney disease (DKD), which is the leading cause of end-stage renal failure worldwide. Dysfunction in the IGF axis, including in IGF binding proteins (IGFBPs), is associated with DKD, particularly in the early stages of disease progression. The aim of this study was to investigate the potential roles of IGFBPs in the development of type 2 DKD, focusing on podocytes.

METHODS

IGFBP expression was analysed in the Pima DKD cohort, alongside data from the Nephroseq database, and in ex vivo human glomeruli. Conditionally immortalised human podocytes and glomerular endothelial cells were studied in vitro, where IGFBP-1 expression was analysed using quantitative PCR and ELISAs. Cell responses to IGFBPs were investigated using migration, cell survival and adhesion assays; electrical cell-substrate impedance sensing; western blotting; and high-content automated imaging.

RESULTS

Data from the Pima DKD cohort and from the Nephroseq database demonstrated a significant reduction in glomerular IGFBP-1 in the early stages of human type 2 DKD. In the glomerulus, IGFBP-1 was predominantly expressed in podocytes and controlled by phosphoinositide 3-kinase (PI3K)-forkhead box O1 (FoxO1) activity. In vitro, IGFBP-1 signalled to podocytes via β1-integrins, resulting in increased phosphorylation of focal-adhesion kinase (FAK), increasing podocyte motility, adhesion, electrical resistance across the adhesive cell layer and cell viability.

CONCLUSIONS/INTERPRETATION

This work identifies a novel role for IGFBP-1 in the regulation of podocyte function and that the glomerular expression of IGFBP-1 is reduced in the early stages of type 2 DKD, via reduced FoxO1 activity. Thus, we hypothesise that strategies to maintain glomerular IGFBP-1 levels may be beneficial in maintaining podocyte function early in DKD.

The role of social prescribers in wales: a consensus methods study

Aims:

Social prescribing continues to grow and change across healthcare services in Wales; however, research of the day-to-day performance of social prescribers is limited. This study aimed to explore which roles are perceived to be the most important and frequently used by social prescribers in Wales and compare these results to reports in studies of services in other countries in order to support future role development and potential standardisation.

Methods:

This study used the Group Concept Mapping via the Concept Systems Global Max™ software to collect and analyse all data from both participants and literature.

Results:

There was a total of 101 statements generated (119 participants, 84 literature) ranging from generic interpersonal skills to specialised training (cognitive behavioural therapy). These statements were then sorted by conceptual similarity into seven clusters (Providing a Specialist Service, Working in a person-centred way, Skills, Connecting Clients with Community, Collaborative Working, Evaluating and postprogramme duties, and Networking/Community). Statements were rated based on their perceived importance and frequency, with the ‘Skills’ cluster having the highest overall average and ‘Providing a Specialist Service’ having the lowest.

Conclusions:

Reports indicate that in general there is variation in the roles performed by individual participants in Wales; however, greater variation was observed between participants and literature suggesting geographical divergence in practice. In the top 12 highest rated statements for both frequency and importance, individualistic traits such as empathy and ‘being a listener’ are favoured over specialised methods such as cognitive behavioural therapy and behaviour change taxonomy. Results suggest that local need plays a part in the choices and performance of social prescribers and as such should be considered in future standardisation.

The Value of Detecting Pathological Changes During Clot Formation in Early Disease Treatment-Naïve Breast Cancer Patients

Breast cancer (BC) is one of the most prevalent forms of cancer in women worldwide. Clinical research indicates that BC patients are at an increased risk for thrombotic events, drastically decreasing their quality-of-life and treatment outcomes. There is ample evidence of this in the literature, but it is mainly focused on metastatic BC. Therefore, coagulopathies of nonmetastatic BC are understudied and require in-depth investigation. In this study, clot kinetics and ultrastructure were used to investigate treatment-naïve, nonmetastatic BC patients using scanning electron microscopy, Thromboelastography®, and confocal laser scanning microscopy. It was demonstrated that nonmetastatic BC patients exhibit minimal ultrastructural alterations of the clot components and no changes in the clot kinetics. However, BC patients presented changes to fibrinogen protein structure, compared to matched controls, using an amyloid-selective stain. Together, these findings suggest that coagulation dysfunction(s) in BC patients with early disease manifest at the microlevel, rather than the macrolevel. This study presents novel insights to a method that are more sensitive to coagulation changes in this specific patient group, emphasizing that the coagulation system may react in different forms to the disease, depending on the progression of the disease itself.

An objective measure of quality for time-scale modification of audio

Objective evaluation of audio processed with time-scale modification (TSM) remains an open problem. Recently, a dataset of time-scaled audio with subjective quality labels was published and used to create an initial objective measure of quality (OMOQ). In this paper, an improved OMOQ for time-scaled audio is proposed. The measure uses handcrafted features and a fully connected network to predict subjective mean opinion scores (SMOS). Basic and advanced perceptual evaluation of audio quality features are used in addition to nine features specific to TSM artefacts. Six methods of alignment are explored with interpolation of the reference magnitude spectrum to the length of the test magnitude spectrum giving the best performance. The proposed measure achieves a mean root mean square error of 0.490 and a mean Pearson correlation of 0.864 to SMOS, equivalent to the 97th and 82nd percentiles of the subjective sessions, respectively. The proposed measure is used to evaluate TSM algorithms, finding that Elastique gives the highest objective quality for solo instrument and voice signals, whereas the identity phase-locking phase vocoder gives the highest objective quality for music signals and the best overall quality. The objective measure is available online at https://www.github.com/zygurt/TSM.

Endoscopic Transfer of Gluteus Maximus and Tensor Fascia Lata for Primary Hip Abductor Deficiency

Complete avulsion of hip abductor muscles may cause severe gait dysfunction and pain. An open surgical procedure to transfer tendons of the gluteus maximus and the tensor fasciae latae to the greater trochanter to make up for the deficient hip abductor has been proposed. The purpose of this study was to describe an endoscopic procedure to transfer gluteus maximus and the tensor fasciae latae to the greater trochanter for hip abductor deficiency.

Apheresis medicine in the era of advanced telehealth technologies: An American Society for Apheresis position paper Part I: Understanding the basic technologies and apheresis medicine practice models

The wide spread availability and use of sophisticated high-speed telecommunication networks coupled with inexpensive and easily accessible computing capacity have catalyzed the creation of new tools and strategies for healthcare delivery. Such tools and strategies are of value to apheresis medicine (AM) practitioners if they improve delivery of patient care, enhance safety during a therapeutic apheresis (TA) intervention, facilitate care access, advance technical capabilities of apheresis devices, and/or elevate quality performance within TA programs. In the past several years, healthcare delivery systems' adoption of telecommunication technologies has been fostered by organizational financial and quality improvement objectives. More recently, adoption of telehealth technologies has been catalyzed by the COVID-19 pandemic as these technologies enhance both patient and provider safety in an era of social distancing. These changes will also influence the delivery of TA services which now can be generally viewed in a tripartite model format comprised of traditional hospital-based fixed site locales, mobile TA operations and lately an evolving telemedicine remote management model now reffered to as telapheresis (TLA). This communication developed by the Public Affairs and Advocacy Committee of the American Society for Apheresis (ASFA) and endorsed by its Board of Directors, reviews and describes various aspects of established and evolving electronic technologies related to TLA and the practice of AM. In subsequent companion publications, additional aspects to TLA will be explored and ASFA's vision of reasonable, regulatory compliant and high-quality TLA practices will be expounded.

A time-scale modification dataset with subjective quality labels

Time Scale Modification (TSM) is a well-researched field; however, no effective objective measure of quality exists. This paper details the creation, subjective evaluation, and analysis of a dataset for use in the development of an objective measure of quality for TSM. Comprised of two parts, the training component contains 88 source files processed using six TSM methods at 10 time scales, while the testing component contains 20 source files processed using three additional methods at four time scales. The source material contains speech, solo harmonic and percussive instruments, sound effects, and a range of music genres. Ratings (42 529) were collected from 633 sessions using laboratory and remote collection methods. Analysis of results shows no correlation between age and quality of rating; expert and non-expert listeners to be equivalent; minor differences between participants with and without hearing issues; and minimal differences between testing modalities. A comparison of published objective measures and subjective scores shows the objective measures to be poor indicators of subjective quality. Initial results for a retrained objective measure of quality are presented with results approaching average root mean squared error loss and Pearson correlation values of subjective sessions. The labeled dataset is available at http://ieee-dataport.org/1987.

Colorectal cancer is associated with increased circulating lipopolysaccharide, inflammation and hypercoagulability

Gut dysbiosis contributes to the development of a dysfunctional gut barrier, facilitating the translocation of bacteria and inflammagens, and is implicated in colorectal cancer (CRC) pathogenesis. Such 'leaky gut' conditions result in systemic inflammation, of which a hallmark is increased hypercoagulability. Fluorescence antibody confocal microscopy was used to determine circulating levels of lipopolysaccharide (LPS) in control and CRC populations. Here we showed that circulating levels of LPS are significantly elevated in the CRC population. We also showed that markers of inflammation and hypercoagulability are increased in this population. Furthermore, anomalous blood clotting and structural changes in blood components are presented. Importantly, the association between LPS levels, inflammation, and hematological dysfunction was analysed. Statistical regression models were applied to identify markers with strong association with CRC, and to investigate the correlation between markers. A core aim is enhanced biomarker discovery for CRC. We conclude that circulating LPS can promote systemic inflammation and contribute to the development of a pathological coagulation system, with resulting chronic inflammation and an activated coagulation system implicated in tumorigenesis. Blood-based screening tools are an emerging research area of interest for CRC screening. We propose the use of additional (novel) biomarkers to effectively screen for CRC.

Femoroacetabular impingement treatment using the arthroscopic extracapsular outside-in approach: Does capsular suture affect functional outcome?

BACKGROUND

Over the last decades, the arthroscopic treatment of hip pathology has highly grown thanks to the evolution of surgical techniques and instrumentation development. An alternative approach consisting in making a first outside-in longitudinal capsulotomy was described by Laude at the end of the 2000s and is experiencing significant development in France. The clinical results of this technique have rarely been reported and in particular the influence of the repair of the capsule is unknown. Therefore we performed a retrospective case control study aiming to asses: (1) the clinical outcomes and complication rates of the outside-in extracapsular approach for the treatment of FemoroAcetabular Impingement (FAI) and (2) the effect of capsular closure on the functional outcome.

HYPOTHESIS

We hypothesize that the outside-in extracapsular approach is a safe and efficient technique and the capsular closure at the end of the procedure positively affects the functional outcome.

METHODS

A retrospective study was conducted on prospectively collected data of a consecutive series of hip arthroscopies performed for surgical treatment of FAI using the outside-in extracapsular approach. Any complications during follow-up were identified and recorded. Linear regression models were used to estimate the influence of capsular closure on the functional outcome. Functional outcome was assessed using modified Harris Hip Score (mHHS) and Non-arthritic Hip Score (NAHS).

RESULTS

Sixty-four hips in 57 patients operated by a single surgeon between October 2013 and December 2016 were analyzed at the time of final follow-up of 34.17 months (range 24 to 53). As the surgical technique evolved over time, a side-to-side capsular closure was performed at the end of the procedure for 25 hips and the capsule was left open for the remaining 39 patients. Functional outcome measurements showed an improvement from the preoperative to the last follow-up: 63.5±11.0 to 88.1±11.2 for mHHS, 63.1±13.8 to 86.4±13.4 for NAHS. Capsular closure leads to a significantly improved clinical outcome: gain in mHHS: 25.8±2.3 vs. 20.6±1.9 (p≤0.044), gain in NAHS: 26.1±2.5 vs. 19.6±2.1, (p=0.023). No major complications occurred. One case of postoperative tensor fascia latae atrophy was documented in the group "capsule left open".

CONCLUSION

Hip arthroscopy in the management of FAI with an extraarticular starting point (outside-in) is a safe technique with functional results and postoperative morbidity comparable to previously reported techniques. Side-to-side capsular closure at the end of the procedure might positively affect the final functional outcome.

Alzheimer's Disease and its Related Dementias among Asian Americans, Native Hawaiians, and Pacific Islanders: A Scoping Review

BACKGROUND

The Asian American, Native Hawaiian, and Pacific Islander (AANHPI) aging population is rapidly growing and the burden of Alzheimer's disease and its related dementias (ADRD) will likely mirror this demographic growth. AANHPIs face significant barriers in obtaining timely ADRD diagnosis and services; yet little is known about ADRD in this population.

OBJECTIVE

The study objective is to conduct a systematic review on the published literature on ADRD among AANHPIs to identify gaps and priorities to inform future research and action plans.

METHODS

The systematic review was conducted following the PRISMA Protocol for Systematic Reviews. Co-author (TR), an experienced Medical Librarian, searched PubMed, EMBASE, PsycINFO, Cochrane Central of Clinical Trials, Ageline, and Web of Science for peer-reviewed articles describing ADRD among AANHPIs. The search was not limited by language or publication date. Each citation was reviewed by two trained independent reviewers. Conflicts were resolved through consensus.

RESULTS

The title/abstract and full texts of 1,447 unique articles were screened for inclusion, yielding 168 articles for analysis. Major research topics included prevalence, risk factors, comorbidities, interventions and outreach, knowledge and attitudes, caregiving, and detection tools. A limited number of studies reported on national data, on NHPI communities generally, and on efficacy of interventions targeting AANHPI communities.

CONCLUSION

To our knowledge, this is the first systematic review on ADRD among AANHPI populations. Our review provides a first step in mapping the extant literature on ADRD among this underserved and under-researched population and will serve as a guide for future research, policy, and intervention.

SYSTEMATIC REVIEW AND GAP ANALYSIS ON ALZHEIMER’S DISEASE IN ASIAN AMERICANS, NATIVE HAWAIIANS, AND PACIFIC ISLANDERS

EMPOWERING OLDER ADULTS IN HEALTHCARE SETTINGS: COMMUNICATION SKILLS TRAINING FOR SURGICAL RESIDENTS

Older adults often perceive themselves as stigmatized and powerless in healthcare settings. Communication with them is complicated by age-related issues and negative stereotypes about older adults and aging. It is therefore vital for physicians and surgeons, who encounter the most vulnerable elderly, to communicate successfully with this population, who wish to maintain quality and dignity in their lives. Successful patient communication leads to better recall of information, compliance, adherence to medications, satisfaction, and overall better outcomes. We developed a two-part training program comprised of small group interactive didactic sessions on aging issues with third year surgical residents, and workshop demonstrations given by the residents to a group of older adults, followed by a question and answer session. Residents were assessed using a 22-item pre–post questionnaire covering medical knowledge of aging, attitudes toward older adults, and personal anxiety about aging. Since its inception, the program has reached 88 residents and 711 older adults. For residents, knowledge scores (p ≤ 0.001), six of nine attitude items (p ≤ 0.01) and one of four anxiety items (p ≤ 0.001) improved significantly. This is notable as well since attitudes and anxiety levels are attributes that are deep-seated and hard to change. For older adults, post surveys showed that 96% strongly agreed/agreed that residents had demonstrated sensitivity toward them and 96% were very satisfied/satisfied with the program. Our replicable, low-cost program enables residents to learn and realistically practice universal underlying communication skills in order to maintain effective and sensitive communication with this vulnerable population.

Efficacy of liposomal bupivacaine in shoulder surgery: a systematic review and meta-analysis

HYPOTHESIS

The aim of this meta-analysis was to compare the safety, efficacy, and opioid-sparing effect of liposomal bupivacaine (LB) vs. nonliposomal local anesthetic agents (NLAs) for postoperative analgesia after shoulder surgery.

METHODS

A systematic literature review of randomized controlled clinical studies comparing the efficacy of LB with NLAs in shoulder surgery was conducted. Seven level I and II studies were included in the meta-analysis, and shoulder surgical procedures included arthroscopic rotator cuff repair and shoulder arthroplasty. Bias was assessed using The Cochrane Collaboration's tool. The primary outcome measures were visual analog scale pain scores and opioid consumption 24 and 48 hours after shoulder surgery. Subgroup analysis was performed for the method of LB administration (interscalene nerve block vs. local infiltration).

RESULTS

A total of 7 studies (535 patients) were included in the final meta-analysis comparing LB (n = 260) with NLAs (n = 275). No significant difference was found between the LB and NLA groups in terms of visual analog scale pain scores at 24 hours (95% confidence interval, -1.02 to 0.84; P = .86) and 48 hours (95% confidence interval, -0.53 to 0.71; P = .78). Both groups had comparable opioid consumption at both 24 hours (P = .43) and 48 hours (P = .78) postoperatively and with respect to length of stay (P = .87) and adverse events (P = .97). Subgroup analysis demonstrated comparable efficacy irrespective of the method of administration of LB.

CONCLUSION

LB is comparable to NLAs with respect to pain relief, the opioid-sparing effect, and adverse effects in the first 48 hours after arthroscopic rotator cuff repair and total shoulder arthroplasty.

Parkinson's Disease: A Systemic Inflammatory Disease Accompanied by Bacterial Inflammagens

Parkinson’s disease (PD) is a well-known neurodegenerative disease with a strong association established with systemic inflammation. Recently, the role of the gingipain protease group from Porphyromonas gingivalis was implicated in Alzheimer’s disease and here we present evidence, using a fluorescent antibody to detect gingipain R1 (RgpA), of its presence in a PD population. To further elucidate the action of this gingipain, as well as the action of the lipopolysaccharide (LPS) from P. gingivalis, low concentrations of recombinant RgpA and LPS were added to purified fluorescent fibrinogen. We also substantiate previous findings regarding PD by emphasizing the presence of systemic inflammation via multiplex cytokine analysis, and demonstrate hypercoagulation using thromboelastography (TEG), confocal and electron microscopy. Biomarker analysis confirmed significantly increased levels of circulating proinflammatory cytokines. In our PD and control blood analysis, our results show increased hypercoagulation, the presence of amyloid formation in plasma, and profound ultrastructural changes to platelets. Our laboratory analysis of purified fibrinogen with added RgpA, and/or LPS, showed preliminary data with regards to the actions of the protease and the bacterial membrane inflammagen on plasma proteins, to better understand the nature of established PD.

Inflammatory cytokines in type 2 diabetes mellitus as facilitators of hypercoagulation and abnormal clot formation

BACKGROUND

The global burden of type 2 diabetes mellitus (T2DM), together with the presence of cardiovascular risk in this population, is reaching pandemic levels. A prominent feature of T2DM is chronic and systemic inflammation, with the accompanying presence of circulating and dysregulated inflammatory biomarkers; which in turn is associated with abnormal clot formation.

METHODS

Here, we investigate the correlation between abnormal blood clotting, using thromboelastography (TEG), clot ultrastructure using scanning electron microscopy (SEM) and the presence of a dysregulated inflammatory cytokine profile, by examining various circulating biomarkers.

RESULTS

Our results show that many biomarkers, across TEG, cytokine and lipid groups, were greatly dysregulated in the T2DM sample. Furthermore, our T2DM sample's coagulation profiles were significantly more hypercoagulable when compared to our heathy sample, and ultrastructural analysis confirmed a matted and denser clot structure in the T2DM sample.

CONCLUSIONS

We suggest that dysregulated circulating molecules may in part be responsible for a hypercoagulable state and vascular dysfunction in the T2DM sample. We propose further that a personalized approach could be of great value when planning treatment and tracking the patient health status after embarking on a treatment regimes, and that looking to novel inflammatory and vascular biomarkers might be crucial.
