Comparison of Adolescent Meningococcal B Vaccination Rates in Four Diverse Outpatient Clinics.

OBJECTIVE: Meningococcal disease, caused by Neisseria meningitidis, is associated with severe illness and death. The Centers for Disease Control and Prevention Advisory Committee on Immunization Practices have published recommendations for the use of meningococcal vaccines in the United States. The primary objective of this study is to compare meningococcal serogroup B vaccination rates among adolescents at 4 diverse outpatient clinics. METHODS: In this retrospective chart review, patients between the ages of 16 and 23 years were identified by using automated dispensing cabinet records of meningococcal serogroup ACWY vaccine removal. Immunization records were reviewed to determine if meningococcal serogroup B vaccine had been administered. Patients from 2 pediatric clinics and 2 family medicine clinics were included in our analysis. RESULTS: Two hundred sixty-five patients were identified for review and 134 patients were included in our study. Of these, 43 (32%) had received the full meningococcal serogroup B vaccine series and 32 (24%) had completed the vaccine series for both meningococcal serogroup B and meningococcal serogroup ACWY series. Most patients who had completed a meningococcal serogroup B vaccine series presented to a pediatric clinic. CONCLUSIONS: Less than half of adolescent patients completed their meningococcal B vaccine series at 4 diverse outpatient clinics, with a greater number of patients receiving vaccinations at pediatric clinics than family medicine clinics. Our findings highlight a need for increased education to providers regarding the current meningococcal B vaccination recommendations.

Combining genomic and epidemiological data to compare the transmissibility of SARS-CoV-2 variants Alpha and Iota.

SARS-CoV-2 variants shaped the second year of the COVID-19 pandemic and the discourse around effective control measures. Evaluating the threat posed by a new variant is essential for adapting response efforts when community transmission is detected. In this study, we compare the dynamics of two variants, Alpha and Iota, by integrating genomic surveillance data to estimate the effective reproduction number (Rt) of the variants. We use Connecticut, United States, in which Alpha and Iota co-circulated in 2021. We find that the Rt of these variants were up to 50% larger than that of other variants. We then use phylogeography to show that while both variants were introduced into Connecticut at comparable frequencies, clades that resulted from introductions of Alpha were larger than those resulting from Iota introductions. By monitoring the dynamics of individual variants throughout our study period, we demonstrate the importance of routine surveillance in the response to COVID-19.

Three-dimensional printing of clinical scale and personalized calcium phosphate scaffolds for alveolar bone reconstruction.

OBJECTIVE: Alveolar bone defects can be highly variable in their morphology and, as the defect size increases, they become more challenging to treat with currently available therapeutics and biomaterials. This investigation sought to devise a protocol for fabricating customized clinical scale and patient-specific, bioceramic scaffolds for reconstruction of large alveolar bone defects. METHODS: Two types of calcium phosphate (CaP)-based bioceramic scaffolds (alginate/ß-TCP and hydroxyapatite/α-TCP, hereafter referred to as hybrid CaP and Osteoink™, respectively) were designed, 3D printed, and their biocompatibility with alveolar bone marrow stem cells and mechanical properties were determined. Following scaffold optimization, a workflow was developed to use cone beam computed tomographic (CBCT) imaging to design and 3D print, defect-specific bioceramic scaffolds for clinical-scale bone defects. RESULTS: Osteoink™ scaffolds had the highest compressive strength when compared to hybrid CaP with different infill orientation. In cell culture medium, hybrid CaP degradation resulted in decreased pH (6.3) and toxicity to stem cells; however, OsteoInk™ scaffolds maintained a stable pH (7.2) in culture and passed the ISO standard for cytotoxicity. Finally, a clinically feasible laboratory workflow was developed and evaluated using CBCT imaging to engineer customized and defect-specific CaP scaffolds using OsteoInk™. It was determined that printed scaffolds had a high degree of accuracy to fit the respective clinical defects for which they were designed (0.27 mm morphological deviation of printed scaffolds from digital design). SIGNIFICANCE: From patient to patient, large alveolar bone defects are difficult to treat due to high variability in their complex morphologies and architecture. Our findings shows that Osteoink™ is a biocompatible material for 3D printing of clinically acceptable, patient-specific scaffolds with precision-fit for use in alveolar bone reconstructive procedures. Collectively, emerging digital technologies including CBCT imaging, 3D surgical planning, and (bio)printing can be integrated to address this unmet clinical challenge.

Combining genomic and epidemiological data to compare the transmissibility of SARS-CoV-2 lineages.

Emerging SARS-CoV-2 variants have shaped the second year of the COVID-19 pandemic and the public health discourse around effective control measures. Evaluating the public health threat posed by a new variant is essential for appropriately adapting response efforts when community transmission is detected. However, this assessment requires that a true comparison can be made between the new variant and its predecessors because factors other than the virus genotype may influence spread and transmission. In this study, we develop a framework that integrates genomic surveillance data to estimate the relative effective reproduction number (R t ) of co-circulating lineages. We use Connecticut, a state in the northeastern United States in which the SARS-CoV-2 variants B.1.1.7 and B.1.526 co-circulated in early 2021, as a case study for implementing this framework. We find that the R t of B.1.1.7 was 6-10% larger than that of B.1.526 in Connecticut in the midst of a COVID-19 vaccination campaign. To assess the generalizability of this framework, we apply it to genomic surveillance data from New York City and observe the same trend. Finally, we use discrete phylogeography to demonstrate that while both variants were introduced into Connecticut at comparable frequencies, clades that resulted from introductions of B.1.1.7 were larger than those resulting from B.1.526 introductions. Our framework, which uses open-source methods requiring minimal computational resources, may be used to monitor near real-time variant dynamics in a myriad of settings.

Child Abuse Response Simulation for Advanced Practice Nursing Students.

PURPOSE: The purpose of this project was for advanced practice nursing students to gain experience taking a history from a parent or caregiver and communicating the treatment plan for an infant in which child abuse is suspected. PROJECT: Fifty-three students participated in a 1:1 simulated encounter with a standardized patient acting as the mother of an infant with a leg injury that reportedly resulted from a fall from the couch. Students received feedback from the standardized patient via an assessment tool and debriefed with faculty immediately after the simulation. OUTCOME: All students demonstrated empathy, acknowledged the mother's emotions, and communicated the concern for abuse. Additionally, all students explained the x-ray findings, need for hospital admission, and referral to investigative agency for further evaluation. CONCLUSION: Simulations designed to provide advanced practice nursing students with experience interviewing a parent and responding in the case of suspected child abuse are an important method of preparing them for initial clinical encounters.

Staying in touch with the community: understanding self-reported health and research priorities in older Aboriginal Australians.

OBJECTIVES: Aboriginal Australians experience higher rates of non-communicable chronic disease, injury, dementia, and mortality than non-Aboriginal Australians. Self-reported health is a holistic measure and may fit well with Aboriginal views of health and well-being. This study aimed to identify predictors of self-reported health in older Aboriginal Australians and determine acceptable research methodologies for future aging research. DESIGN: Longitudinal, population-based study. SETTING: Five communities across New South Wales, Australia (two urban and three regional sites). PARTICIPANTS: Aboriginal and Torres Strait Islander people (n = 227; 60-88 years, M = 66.06, SD = 5.85; 145 female). MEASUREMENTS: Participants completed baseline (demographic, medical, cognitive, mental health, and social factors) and follow-up assessments (self-reported health quantified with 5-point scale; sharing thoughts on areas important for future research). Predictors of self-reported health were examined using logistic regression analyses. RESULTS: Self-reported health was associated with sex, activities of daily living, social activity participation, resilience, alcohol use, kidney problems, arthritis, falls, and recent hospitalization. Arthritis, kidney problems, and resilience remained significant in multiple logistic regression models. CONCLUSIONS: Perceived resilience and the absence of certain chronic age-related conditions predict older Aboriginal peoples' self-reported health. Understanding these factors could inform interventions to improve well-being. Findings on acceptable research methodologies suggest that many older Aboriginal people would embrace a range of methodologies within long-standing research partnerships, which is an important consideration for Indigenous population research internationally.

Shared Participatory Research Principles and Methodologies: Perspectives from the USA and Brazil-45 Years after Paulo Freire's "Pedagogy of the Oppressed".

The trajectory of participation in health research by community social actors worldwide has been built on a history of community participation from the Ottawa Charter Health Promotion call for community mobilization, to the emancipatory educational philosophy of Paulo Freire, to social movements and organizing for health and social justice. This paper builds on this history to expand our global knowledge about community participation in research through a dialogue between experiences and contexts in two prominent countries in this approach; the United States and Brazil. We first focus on differences in political and scientific contexts, financing, and academic perspectives and then present how, despite these differences, similarities exist in values and collaborative methodologies aimed at engaging community partners in democratizing science and knowledge construction. We present three case studies, one from the U.S. and two from Brazil, which illustrate similar multi-level processes using participatory research tools and Freirian dialogue to contribute to social mobilization, community empowerment, and the transformation of inequitable societal conditions. Despite different processes of evolution, we observed a convergence of participatory health research strategies and values that can transform science in our commitment to reduce health and social inequities and improve community wellbeing.

Creating a data resource: what will it take to build a medical information commons?

National and international public-private partnerships, consortia, and government initiatives are underway to collect and share genomic, personal, and healthcare data on a massive scale. Ideally, these efforts will contribute to the creation of a medical information commons (MIC), a comprehensive data resource that is widely available for both research and clinical uses. Stakeholder participation is essential in clarifying goals, deepening understanding of areas of complexity, and addressing long-standing policy concerns such as privacy and security and data ownership. This article describes eight core principles proposed by a diverse group of expert stakeholders to guide the formation of a successful, sustainable MIC. These principles promote formation of an ethically sound, inclusive, participant-centric MIC and provide a framework for advancing the policy response to data-sharing opportunities and challenges.

Transmission of Salmonella enteritidis after endoscopic retrograde cholangiopancreatography because of inadequate endoscope decontamination.

We report a historic nosocomial outbreak of Salmonella enteritidis affecting 4 inpatients who underwent endoscopic retrograde cholangiopancreatography. The cause was attributed to inadequate decontamination of an on-loan endoscope used over a weekend. This report highlights the risks of using on-loan endoscopes, particularly regarding their commissioning and adherence to disinfection protocols. In an era of increasing antibiotic resistance, transmission of Enterobacteriaceae by endoscopes remains a significant concern.

Changes in Outcomes, Satiety and Adverse Upper Gastrointestinal Symptoms Following Laparoscopic Adjustable Gastric Banding.

BACKGROUND: Patient-reported outcomes and perceptions are critical to the overall efficacy and acceptability of a surgical procedure. Outcomes, such as patient satisfaction and perceived success of the surgery and adverse symptoms, have not been described in detail following bariatric surgery. The associations and predictors of patient satisfaction have not been defined. This study aimed to examine long-term outcomes and perceptions after laparoscopic adjustable gastric banding (LAGB). METHODS: We conducted a prospective study of outcomes, satiety and adverse upper gastrointestinal symptoms, as well as quality of life and subjective patient satisfaction in LAGB patients. Data were collected at 3 years (T1) and 8 years post-operatively (T2). RESULTS: One-hundred and sixty patients completed follow-up at T1 and T2. The average age was 44.0 ± 11.2 years. At T2, the total body weight loss was 17.8 ± 11.9 %. Satisfaction decreased significantly between time points (8.6 ± 1.8 vs 7.2 ± 2.9, p < 0.01), and quality of life reduced slightly across all domains. Hunger scores remained low (3.8 ± 1.8 vs 3.9 ± 1.8, p = 0.61). The dysphagia score did not change significantly (p = 0.54). There was minimal change in frequency of regurgitation, although there was significant increase in patient assessment of how bothered they were by regurgitation. Multivariate analysis identified increased awareness of regurgitation as a principal driver of reduced satisfaction. CONCLUSIONS: Weight loss, satiety and adverse symptoms demonstrated only slight changes between 3 and 8 years post-operatively. Despite this, overall satisfaction and perception of success of the procedure reduced markedly. This appeared mediated by reduced tolerance of adverse symptoms. These data inform follow-up practises aimed at optimizing outcomes.

On the path to a science of patient input.

It is early days in the creation of a science of patient input. Participants are establishing rigorous methods to better integrate patient perspectives, needs, and priorities throughout biomedical and bioengineering R&D and care delivery to patients. To assess progress and unmet needs, FasterCures tracked more than 70 collaborative initiatives clustered in six categories that are defining and shaping this developing field. No longer is patient engagement a fanciful notion as it was at the start of our journey in 2003, and the rush of activity is welcome and vital.

Concurrent Large Para-oesophageal Hiatal Hernia Repair and Laparoscopic Adjustable Gastric Banding: Results from 5-year Follow Up.

OBJECTIVE: The objective of the study is to identify the efficacy and safety of combining laparoscopic adjustable gastric banding with repair of large para-oesophageal hernias. BACKGROUND: Para-oesophageal hernias are more common in the obese with higher recurrence rates following repair. The effect and safety of combining para-oesophageal hernia repair with laparoscopic adjustable gastric banding is unknown. METHODS: One-hundred fourteen consecutive patients undergoing primary laparoscopic adjustable gastric banding with concurrent repair of a large para-oesophageal hernia were prospectively identified and matched to a control group undergoing primary laparoscopic adjustable gastric banding only. Weight loss and complication data were retrieved from a prospectively maintained database, and a standardised bariatric outcome questionnaire was used to assess post-operative symptoms, satisfaction with surgery and satiety scores. RESULTS: At a mean follow up of 4.9 ± 2.1 years, total weight loss was 16.4 ± 9.9% in the hernia repair group and 17.6 ± 12.6% in the control group (p = 0.949), with 17 vs. 11% loss to follow up rates (p = 0.246). No statistically significant difference in revisional surgery rate and symptomatic recurrence of hiatal hernia was documented in four patients in the hernia repair group (3.5%). No statistically significant difference in mean reflux (9.9 vs. 10.3, p = 0.821), dysphagia (20.7 vs. 20.1, p = 0.630) or satiety scores was identified. CONCLUSIONS: Concurrent repair of large para-oesophageal hiatal hernia and laparoscopic adjustable gastric banding placement is safe and effective both in terms of symptom control and weight loss over the intermediate term. In obese patients with large hiatal hernias, consideration should be given to combining repair of the hernia with a bariatric procedure.

The Effect of Weight Loss on Indigenous Australians with Diabetes: a study of Feasibility, Acceptability and Effectiveness of Laparoscopic Adjustable Gastric Banding.

BACKGROUND/OBJECTIVES: Diabetes and obesity are common and serious health challenges for indigenous people worldwide. The feasibility of achieving substantial weight loss, leading to remission of diabetes, was evaluated in a regional indigenous Australian community. SUBJECTS/METHODS: A prospective cohort study of 30 obese indigenous adults from the Rumbalara Aboriginal Co-operative in Central Victoria was performed. Inclusion criteria included aboriginality, BMI > 30 kg/m(2) and diabetes diagnosed within the last 10 years. Weight loss was achieved using laparoscopic adjustable gastric banding (LAGB). Participants were treated in their community and followed for 2 years. Outcomes were compared with those of non-indigenous Australians from an earlier randomized controlled trial (RCT) using a similar protocol. RESULTS: 30 participants (26 females, mean age 44.6 years; mean BMI 44.3) had LAGB at the regional hospital. Twenty-six participants completed diabetes assessment at 2 years follow-up. They showed diabetes remission (fasting blood glucose < 7.0 mmol/L and haemoglobin A1c (HbA1c) < 6.2 % while off all therapy except metformin) in 20 of the 26 and a mean weight loss (SD) of 26.0 (14) kilograms. Based on intention-to-treat, remission rate was 66 %. Quality of life improved. There was one early event and 12 late adverse events. The outcomes for weight loss and diabetes remission were not different from the LAGB group of the RCT. CONCLUSIONS: For obese indigenous people with diabetes, a regionalized model of care centred on the LAGB is an effective approach to a serious health problem. The model proved feasible and acceptable to the indigenous people. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry (ACTRN 12609000319279).

Environmental and microbial factors influencing methane and nitrous oxide fluxes in Mediterranean cork oak woodlands: trees make a difference.

Cork oak woodlands (montado) are agroforestry systems distributed all over the Mediterranean basin with a very important social, economic and ecological value. A generalized cork oak decline has been occurring in the last decades jeopardizing its future sustainability. It is unknown how loss of tree cover affects microbial processes that are consuming greenhouse gases in the montado ecosystem. The study was conducted under two different conditions in the natural understory of a cork oak woodland in center Portugal: under tree canopy (UC) and open areas without trees (OA). Fluxes of methane and nitrous oxide were measured with a static chamber technique. In order to quantify methanotrophs and bacteria capable of nitrous oxide consumption, we used quantitative real-time PCR targeting the pmoA and nosZ genes encoding the subunit of particulate methane mono-oxygenase and catalytic subunit of the nitrous oxide reductase, respectively. A significant seasonal effect was found on CH4 and N2O fluxes and pmoA and nosZ gene abundance. Tree cover had no effect on methane fluxes; conversely, whereas the UC plots were net emitters of nitrous oxide, the loss of tree cover resulted in a shift in the emission pattern such that the OA plots were a net sink for nitrous oxide. In a seasonal time scale, the UC had higher gene abundance of Type I methanotrophs. Methane flux correlated negatively with abundance of Type I methanotrophs in the UC plots. Nitrous oxide flux correlated negatively with nosZ gene abundance at the OA plots in contrast to that at the UC plots. In the UC soil, soil organic matter had a positive effect on soil extracellular enzyme activities, which correlated positively with the N2O flux. Our results demonstrated that tree cover affects soil properties, key enzyme activities and abundance of microorganisms and, consequently net CH4 and N2O exchange.

Overcoming obstacles to repurposing for neurodegenerative disease.

Repurposing Food and Drug Administration (FDA)-approved drugs for a new indication may offer an accelerated pathway for new treatments to patients but is also fraught with significant commercial, regulatory, and reimbursement challenges. The Alzheimer's Drug Discovery Foundation (ADDF) and the Michael J. Fox Foundation for Parkinson's Research (MJFF) convened an advisory panel in October 2013 to understand stakeholder perspectives related to repurposing FDA-approved drugs for neurodegenerative diseases. Here, we present opportunities on how philanthropy, industry, and government can begin to address these challenges, promote policy changes, and develop targeted funding strategies to accelerate the potential of FDA-approved repurposed drugs.

Service, training and outreach--the EARS Inc. Model for a self sustainable hearing program in action.

PURPOSE: EARS Inc. is a faith based not-for-profit organization established in 1998. As an organization, it has consistently maintained a goal to provide both short-term and long-term projects in low and middle income countries. One specific project undertaken by EARS Inc involved developing a hearing health program in the Dominican Republic. METHODS: This article is a review of the challenges and successes encountered on the road to establishing improved access and affordability of hearing aid technology for the hearing impaired in Domincan Republic. RESULTS: Despite the challenges, after 12 years of local programming, the hearing health services in the Dominican Republic were successfully implemented. The development of these services included the simultaneous development of a training program, earmould laboratory, hearing aid repair services as well as calibration services and sales of batteries and accessories. CONCLUSIONS: As demonstrated in this review, it is possible to develop sustainable and comprehensive diagnostic and rehabilitation hearing services in a developing country. It is clear that training, equipping and empowering local staffs are instrumental to the success of the program. IMPLICATIONS FOR REHABILITATION: A good hearing aid fitting is more than supplying technology. Patient education and the clinician fitting the hearing aid are important. Access to follow-up services including battery supplies, hearing aid adjustments and hearing aid repairs is essential for a hearing aid fitting program in low and middle income countries to be sustainable. Check the WHO guidelines for hearing aid provision in developing countries when planning a program. When working in a country, co-ordinate with local professionals involved in hearing health where available.
