Anomalously weak Labrador Sea convection and Atlantic overturning during the past 150 years.

The Atlantic meridional overturning circulation (AMOC) is a system of ocean currents that has an essential role in Earth's climate, redistributing heat and influencing the carbon cycle1, 2. The AMOC has been shown to be weakening in recent years 1 ; this decline may reflect decadal-scale variability in convection in the Labrador Sea, but short observational datasets preclude a longer-term perspective on the modern state and variability of Labrador Sea convection and the AMOC1, 3-5. Here we provide several lines of palaeo-oceanographic evidence that Labrador Sea deep convection and the AMOC have been anomalously weak over the past 150 years or so (since the end of the Little Ice Age, LIA, approximately AD 1850) compared with the preceding 1,500 years. Our palaeoclimate reconstructions indicate that the transition occurred either as a predominantly abrupt shift towards the end of the LIA, or as a more gradual, continued decline over the past 150 years; this ambiguity probably arises from non-AMOC influences on the various proxies or from the different sensitivities of these proxies to individual components of the AMOC. We suggest that enhanced freshwater fluxes from the Arctic and Nordic seas towards the end of the LIA-sourced from melting glaciers and thickened sea ice that developed earlier in the LIA-weakened Labrador Sea convection and the AMOC. The lack of a subsequent recovery may have resulted from hysteresis or from twentieth-century melting of the Greenland Ice Sheet 6 . Our results suggest that recent decadal variability in Labrador Sea convection and the AMOC has occurred during an atypical, weak background state. Future work should aim to constrain the roles of internal climate variability and early anthropogenic forcing in the AMOC weakening described here.

Bleeding and ketorolac use in pediatric circumcision.

BACKGROUND: Circumcision is a common surgical procedure performed in pediatric male patients. Ketorolac is an effective adjunct in multimodal regimens for postoperative pain control. However, many urologists and anesthesiologists refrain from administering ketorolac due to concern for postoperative bleeding. AIMS: Compare the risk of clinically significant bleeding after circumcision with and without intraoperative ketorolac administration. METHODS: A single-center, retrospective cohort study was conducted of pediatric patients 1-18 years of age who underwent isolated circumcision by one urologist from 2016 to 2020. Clinically significant bleeding was defined as bleeding requiring intervention within the first 24 h of circumcision. Interventions included use of absorbable hemostats, placement of sutures, or return to the operating room. RESULTS: Of 743 patients, 314 (42.3%) did not receive ketorolac and 429 (57.7%) received intraoperative ketorolac 0.5 mg/kg. Postoperative bleeding requiring intervention occurred in one patient (0.32%) in the non-ketorolac group versus four patients (0.93%) in the ketorolac group (difference 0.6%, 95% CI [-0.8%, 2.0%], p = 0.403). CONCLUSIONS: There was no statistically significant difference in postoperative bleeding requiring intervention between the non-ketorolac and ketorolac groups. Future studies regarding the association between ketorolac and postoperative bleeding are needed.

Developing a Public Health Maternal and Child Health Training Program: Lessons Learned from Five Schools of Public Health.

Maternal and child health (MCH), as a core sub-field of public health, continues to be an essential area in which additional workforce development and investment are needed. Recent public health workforce assessments in the United States reveal there will be a significant number of vacancies in MCH public health positions in the near future, creating the need for a well-trained and skilled public health MCH workforce. In order to address this potential critical workforce gap, the U.S. Department of Health and Human Services, Health Resources and Services Administration's Maternal and Child Health Bureau initiated the Maternal and Child Health Public Health Catalyst Program in 2015 to support the creation of MCH training programs in accredited schools of public health that previously did not have a MCH concentration. This article details the accomplishments and lessons learned from the first five MCH Catalyst Program grantees: Drexel University; Florida International University; Rutgers, The State University of New Jersey; Texas A&M University; and the University at Albany.

Experiences of weight stigma in adolescents with severe obesity and their families.

AIM: To describe the experiences of weight stigma in adolescents with severe obesity and their parents. DESIGN: Qualitative descriptive secondary analysis. METHODS: A secondary analysis on 31 transcripts from a larger study of 46 transcripts conducted between February 2019 and June 2020. Semi-structured interviews were conducted with 19 parents (n = 17 mothers, n = 2 fathers) and 12 adolescents (n = 7 male, n = 5 female). Interviews were digitally audio recorded, transcribed and analysed using conventional content analysis. RESULTS: Four common themes were identified reflecting experiences of weight stigma: weight-based teasing and bullying, interactions with healthcare providers (HCPs), family interactions and blame. Subthemes were fairness and impact on mental health. CONCLUSION: This secondary analysis adds to the sparse literature documenting the experiences of weight stigma from adolescents with severe obesity and their families. It is important to understand the experiences of weight stigma from the adolescent and parent perspective as it can inform healthcare, education and policies across communities and facilitate holistic health for this vulnerable population. IMPACT: The need for research to better understand how experiences of weight stigma correlate with physiological and psychological outcomes and inform innovative interventions are critical to improve treatment of severe obesity. Healthcare providers across disciplines are in a strategic position to change the paradigm through which we provide care to youth with severe obesity and guide families in supporting their children's weight management efforts without contributing to weight stigma.

The mycelium of the Trametes versicolor (Turkey tail) mushroom and its fermented substrate each show potent and complementary immune activating properties in vitro.

BACKGROUND: The medicinal mushroom Trametes versicolor (Tv, Turkey Tail) is often prepared for consumption as a powder from the fungal mycelium and the fermented substrate on which it grew. The goal for this study was to evaluate the immune-modulating properties of the mycelium versus the fermented substrate, to document whether an important part of the immune-activating effects resides in the metabolically fermented substrate. METHODS: Tv mycelium was cultured on rice flour. The mycelium and the fermented substrate were mechanically separated, dried, and milled. The initial substrate served as a control. Aqueous fractions were extracted and passed through 0.22-µm filters. The remaining solids were passed through homogenization spin columns without filtration. The aqueous and solid fractions of the initial substrate (IS), the fermented substrate (FS), and the Trametes versicolor mycelium (TvM) were tested for immune-activating and modulating activities on human peripheral blood mononuclear cell cultures, to examine expression of the CD69 activation marker on lymphocytes versus monocytes, and on the T, NKT, and NK lymphocyte subsets. Culture supernatants were tested for cytokines using Luminex arrays. RESULTS: Both aqueous and solid fractions of TvM triggered robust induction of CD69 on lymphocytes and monocytes, whereas FS only triggered minor induction of CD69, and IS had no activating effect. The aqueous extract of TvM had stronger activating effects than the solid fraction. In contrast, the solid fraction of IS triggered a reduction in CD69, below levels on untreated cells. Both aqueous and solid fractions of FS triggered large and dose-dependent increases in immune-activating pro-inflammatory cytokines (IL-2, IL-6), anti-inflammatory cytokines Interleukin-1 receptor antagonist (IL-1ra) and Interleukin-10 (IL-10), anti-viral cytokines interferon-gamma (IFN-γ) and Macrophage Inflammatory Protein-alpha (MIP-1α), as well as Granulocyte-Colony Stimulating Factor (G-CSF) and Interleukin-8 (IL-8). TvM triggered more modest cytokine increases. The aqueous extract of IS showed no effects, whereas the solid fraction showed modest effects on induction of cytokines and growth factors. CONCLUSION: The results demonstrated that the immune-activating bioactivity of a mycelial-based medicinal mushroom preparation is a combination of the mycelium itself (including insoluble beta-glucans, and also water-soluble components), and the highly bioactive, metabolically fermented substrate, not present in the initial substrate.

Vitamin D Screening Variations in Children and Adolescents: Who should be Screened?

PROBLEM: No consensus on vitamin D deficiency (VDD) screening in children and adolescents exists. Early VDD detection can improve the health of children. VDD can cause bone mineralization diseases, such as rickets in children. The purpose of this review is to determine existing VDD screening recommendations or clinical practice guidelines in children and adolescents. ELIGIBILITY CRITERIA: Inclusion criteria were VDD screening 'guideline', 'clinical practice guideline', and 'recommendations' for children and adolescents in English, published 2001-2018. RESULTS: Eight current guidelines addressed VDD screening recommendations with the common recommendation results endorsing screening only for VDD in at-risk children and adolescents. CONCLUSIONS: There is insufficient evidence for pediatric healthcare providers to recommend which VDD risk factors should be utilized for screening in children and adolescents. IMPLICATIONS: Further studies should focus on developing a validated VDD screening tool for children and adolescents based on risk factors.

A Narrative Review of Patient and Family Engagement: The "Foundation" of the Medical "Home".

BACKGROUND: Patient and family engagement (PFE) is vital to the spirit of the medical home. This article reflects the efforts of an expert consensus panel, the Patient and Family Engagement Workgroup, as part of the Society of General Internal Medicine's 2013 Research Conference. OBJECTIVE: To review extant literature on PFE in pediatric and adult medicine and quality improvement, highlight emerging best practices and models, suggest questions for future research, and provide references to tools and resources to facilitate implementation of PFE strategies. METHODS: We conducted a narrative review of relevant articles published from 2000 to 2015. Additional information was retrieved from personal contact with experts and recommended sources from workgroup members. RESULTS: Despite the theoretical importance of PFE and policy recommendations that PFE occurs at all levels across the health care system, evidence of effectiveness is limited, particularly for quality improvement. There is some evidence that PFE is effective, mostly related to engagement in the care of individual patients, but the evidence is mixed and few studies have assessed the effect of PFE on health outcomes. Measurement issues and the lack of a single comprehensive conceptual model pose challenges to progress in this field. Recommendations for future research and a list of practical tools and resources to facilitate PFE are provided. CONCLUSIONS: Although PFE appeals to patients, families, providers, and policy-makers, research is needed to assess outcomes beyond satisfaction, address implementation barriers, and support engagement in practice redesign and quality improvement. Partnering with patients and families has great potential to support high-quality health care and optimize outcomes.

Evaluation of a statewide medical home program on children and young adults with asthma.

OBJECTIVE: Asthma, the most common chronic condition among children, accounts for significant healthcare utilization and impact on quality of life. Care coordination in a medical home is considered standard practice, but has not been rigorously evaluated. METHODS: We initiated this pilot study of children/young adults with asthma (n = 967), ages: birth to 24 years, receiving care from a subset of pediatric practices (n = 20) participating in the Pennsylvania Medical Home Initiative, Educating Practices in Community-Integrated Care (92 practices statewide). We hypothesized children and youth with asthma receiving care coordination in the context of a formal medical home program would experience favorable associations with healthcare utilization and quality of life measures. RESULTS: A total of 9240 care coordination encounters for this cohort of children/youth occurred over 100 days. The average length of care coordination encounter was 20.7 minutes. The most common care coordination activity was referral management (21%) and the care coordinator in the practice most often contacted parent/family and specialists (75%). Children with more severe asthma had more hospitalizations and emergency department (ED) visits than children with less severe asthma. There was a significant decrease in school absences, ED visits and acute care visits for children/youth with asthma with increasing length of time in a medical home program (p < 0.05). CONCLUSION: Care coordination for children/youth with asthma is feasible and may yield improvements in healthcare utilization, expenditures and quality of life. Larger-scale implementation of care coordination and medical home models for children/youth with asthma and other diagnoses are warranted.

Successful implementation and use of a learning management system.

The evolving world of technology has impacted nursing education in various ways. Implementing a learning management system provides a dynamic approach to traditional teaching methods. The key to successful implementation is communication. This article expands on the implementation process of a learning management system and the processes that were significantly improved due to this technology.

Reexamining the complex issue of obesity in childhood: A new guideline and patient-focused approach.

ABSTRACT: Obesity in childhood is a complex, multifaceted condition with various contributors, including genetic, environmental, socioeconomic, and physiologic factors. The latest guidelines recommend annual evaluation beginning at age 2 years. Treatment strategies should be family focused and should target nutrition, physical activity, and behavior.

A Virtual Home Preparedness Intervention Centered on Children and Youth With Special Health Care Needs.

OBJECTIVE: Children and youth with special health care needs (CYSHCN) require additional considerations for staying safe in emergencies. Our team of clinicians and preparedness professionals developed and tested a virtual home preparedness intervention (VHPI) in families with CYSHCN receiving care in a statewide medical home network. METHODS: The VHPI comprised 1) a pre/post interview covering fire safety, emergency evacuation, sheltering in place, and informing emergency responders of the child/youth's care needs; 2) a resource packet containing emergency planning templates and information on local supports; and 3) individualized referrals coordinated through the medical home/community partners. Eligible CYSHCN had medical technology reliance, physical/mobility needs, communication/intellectual challenges, and/or vision/hearing loss. Preparedness was measured as pre/post affirmed rates of 19 items from the interview and as mean composite scores of these items; associations were evaluated using generalized estimating equations-based regression for repeated measures. RESULTS: The pre and post-VHPI interviews were completed by 170 and 148 participants, respectively. Significant individual-item gains included having a current Emergency Information Form for the child/youth (31% [pre] to 47% [post] affirmed) and assembling an evacuation kit (50% to 68%). The mean preparedness score was 13.33/19 items affirmed at baseline and increased to 14.96 post-VHPI (P < .01). In the adjusted regression model, the post-intervention preparedness score remained significantly higher than pre-VHPI, with mean increases of 1.22 preparedness steps affirmed for homeowners and 1.85 for renters. CONCLUSIONS: Preparedness scores improved post-VHPI in families with CYSHCN. Future work should address incorporating the VHPI into care visits in the medical home.

Congenital peritoneal encapsulation and superior mesenteric vein thrombosis: A case report.

Congenital peritoneal encapsulation is a rare entity characterized by an accessory peritoneal membrane that forms during embryonic development. Congenital peritoneal encapsulation is generally asymptomatic but can cause intermittent, colicky abdominal pain related to subacute small bowel obstruction. Diagnosis is made incidentally or upon surgical exploration for chronic abdominal complaints as preoperative imaging is typically nonspecific. We report a case of a 49-year-old male with epigastric abdominal pain, constipation, and superior mesenteric vein thrombosis on imaging. Upon exploratory laparotomy, the small bowel was covered by an accessory peritoneal sac consistent with congenital peritoneal encapsulation. The accessory sac was excised completely, and the patient recovered well. Although rarely causing significant gastrointestinal symptoms, congenital peritoneal encapsulation is an anomaly that requires surgical intervention.

Family Experience of Caregiver Burden and Health Care Usage in a Statewide Medical Home Program.

OBJECTIVE: To evaluate family-reported caregiver experiences and health care utilization of patients enrolled in the Pennsylvania Medical Home Program (PA-MHP) statewide practice network and compare results to PA-MHP practices' Medical Home Index (MHI) scores. We hypothesized families enrolled in higher-scoring patient-and-family-centered medical homes (PCMH) on completed MHIs would report decreased caregiver burden and improved health care utilization. METHODS: We analyzed surveys completed by families receiving care coordination services in PA-MHP's network and each practice's mean MHI score. A total of 3221 caregivers completed surveys evaluating hours spent coordinating care/week, missed school/workdays, sick visits, and emergency department (ED) visits. A total of 222 providers from 54 participating PA-MHP practices completed the nationally recognized MHI. Family/practice demographics were collected. We developed multivariate logistic regression models assessing independent associations among family survey outcomes and corresponding practices' MHI scores. RESULTS: Families enrolled in high-scoring PCMHs had decreased odds of spending >1 h/wk coordinating care (odds ratio [OR] 0.82, adjusted OR [aOR]: 0.70, 95% confidence interval [CI] 0.55-0.90), missing workdays in the past 6 months (OR 0.82, aOR: 0.72, 95% CI 0.69-0.97), and ED visits in the past 12 months (OR 0.83, aOR: 0.81, 95% CI 0.65-0.99) in comparison to families enrolled in lower-scoring PCMHs. Families enrolled in higher-scoring PCMHs did not report fewer sick visits despite fewer ED visits, indicating more appropriate health care utilization. High-scoring PCMHs had lower percentages of publicly insured and low-income children. CONCLUSIONS: Higher-scoring PCMHs are associated with decreased caregiver burden and improved health care utilization across diverse PA practices. Future studies should evaluate interventions uniformly improving PCMH quality and equity.

Communication Preferences of Parents and Caregivers of Children and Youth With Special Healthcare Needs During a Hypothetical Infectious Disease Emergency.

Children and youth with special healthcare needs are at risk for severe consequences during infectious disease emergencies. Messages for parents and caregivers from trusted sources, via preferred channels, that contain the information they need, may improve health outcomes for this population. In this mixed methods study, we conducted a survey (N = 297) and 80 semistructured interviews, with 70 caregivers of children and youth and 10 young adults with special healthcare needs, between April 2018 and June 2019 in Pennsylvania. The survey presented 3 scenarios (ie, storm, disease outbreak, radiation event); the interviews included questions about storms and an outbreak. This article addresses only the disease outbreak data from each set. Participants were recruited through convenience samples from an urban tertiary care children's hospital and practices in a statewide medical home network. In this article, we summarize the preferred information sources, channels, and content needs of caregivers of children and youth with special healthcare needs during an infectious disease emergency. Nearly 84% of caregivers reported that they believe their child's doctor is the best source of information. Other preferred sources include medical experts (31%); the US Centers for Disease Control and Prevention (30%); friends, family, and neighbors (21%); and local or state health and emergency management (17%). Pediatric healthcare providers play an important role in providing information to parents and caregivers of children and youth with special healthcare needs during an infectious disease emergency. Public health agencies can establish health communication plans that integrate medical practices and other reliable sources to promote the dissemination of accurate information from trusted messengers.

We will remember them: The Canadian Armed Forces's Casualty Identification Program.

The 2003 discovery of two sets of human skeletal remains of Canadian soldiers killed in action during the First World War revitalized the Canadian Armed Forces's responsibility for identifying and burying its war dead from the First and Second World Wars. In 2007, the Casualty Identification Program was formally established with a mandate of identifying newly discovered remains of Canadian soldiers and airmen.1 The Program is now also responsible for adjudicating research into identifying remains previously interred as an "unknown" soldier or airman. The Casualty Identification Program's tenets (e.g., equality in death) and procedures (e.g., no repatriation-the remains are buried in the closest appropriate cemetery to where they fell) are closely linked to policies established in 1917 with the creation of the Imperial War Graves Commission (now the Commonwealth War Graves Commission), of which the governments of Canada and Newfoundland were signatories. In modern investigations into the identity of newly discovered human skeletal remains, historical, archaeological, anthropological, odontological, and genealogical research, as well as stable isotope and DNA analysis, can be included in the Casualty Identification Program's process. It is the principal goal of the Program to ensure that fallen Canadian service members are recognized as soldiers and airmen who died for Canada with their name and buried alongside their comrades.

Differential Immune Activating, Anti-Inflammatory, and Regenerative Properties of the Aqueous, Ethanol, and Solid Fractions of a Medicinal Mushroom Blend.

PURPOSE: To compare three fractions of a medicinal mushroom blend (MMB), MyCommunity, on immune-activation, inflammation-regulation, and induction of biomarkers involved in regenerative functions. METHODS: A seventeen-species MMB was sequentially extracted: first, saline solution at ambient temperature, followed by re-extraction of the solids in ethanol, and finally resuspension of the homogenized ethanol-insoluble solids in cell-culture media. Fractions were tested on peripheral blood mononuclear cells from three healthy donors. Immunostaining, flow-cytometry, and Luminex protein-arrays measured immune-cell activation and cytokine response. Dose-responses for induction of the CD69 early activation marker and individual cytokine and growth-factor responses for each donor were evaluated. The CD69 and the combined cytokine and growth-factor results were subjected to Non-metric Multidimensional Scaling (NMDS) and multivariate ordination to aid interpretation of the aggregate immune response and pairwise permutational MANOVA on a distance-matrix to evaluate statistical differences between treatments on pooled data from all donors. RESULTS: Differential effects were induced by water-soluble, ethanol-soluble, and insoluble immunomodulatory compounds of the MMB. The aqueous and ethanol fractions upregulated expression of CD69 on all tested cell types. Monocyte-activation was correlated with the ethanol fraction, while NKT and non-NK non-T cell-activation was more closely correlated with the aqueous fraction. The solid fraction was the most potent inducer of Tumor Necrosis Factor-α, as well as the anti-viral cytokines interferon-γ, MCP-1 (CCL-2), MIP-1α (CCL-3), and MIP-1ß (CCL-4), and induced G-CSF and b-FGF-growth-factors involved in regenerative functions-and the anti-inflammatory cytokine IL-1ra. CONCLUSION: The aqueous, ethanol, and insoluble compounds within MMB induced differential immune-activating, anti-inflammatory, and regenerative effects. This in vitro data suggests that, upon consumption, MMB may induce a concerted series of immunomodulatory events based on the differential solubility and bioavailability of the active constituents. These differential responses support both immune-activation and resolution of the host defense-induced inflammatory reactions, thus assisting a post-response return to homeostasis.

Children With Special Needs: Social Determinants of Health and Care Coordination.

Care coordination (CC) facilitates access to resources/services for children/youth with special health care needs (CYSHCN). We conducted a cross-sectional analysis of the 2009-2010 National Survey of CSHCN to examine socioeconomic factors related to report of receiving adequate CC services for CYSHCN. Descriptive statistics were used to describe sociodemographic characteristics of respondents and examine socioeconomic factors. Receiving adequate CC varied by socioeconomic variables including income (100% to 199% federal poverty line [FPL]; aOR [adjusted odds ratio] = 0.848; 95% CI [confidence interval] = 0.722-0.997; P < .05), insurance (uninsured; aOR = 0.446; 95% CI = 0.326-0.609; P < .0001), and marital status (never married; aOR = 0.79; 95% CI = 0.64-0.97; P < .05). More families reporting adequate CC had private insurance, non-Hispanic white ethnicity, income >400% federal poverty level, and 2-parent households. Findings suggest unmet needs in terms of adequate access or knowledge leading to insufficient provision of CC for families with the greatest needs. Further analysis identifying specific deficits and implementing strategies to address these disparities is warranted.

Identifying Caregiver Needs for Children With a Tracheostomy Living at Home.

This study sought to understand caregiver needs of children with tracheostomies (CWT) living at home and inform development of standardized tracheostomy simulation training curricula. Long-term goals are decreasing hospital readmissions following tracheostomy placement and improving family experiences while implementing a medical home model. We recruited caregivers of CWT and conducted semistructured interviews, subsequently recorded, transcribed, and analyzed for emerging themes using NVivo. Demographic data were collected via quantitative surveys. Twenty-seven caregivers participated. Emerging themes included the following: (1) caregivers felt overwhelmed, sad, frightened when learning need for tracheostomy; (2) training described as adequate, but individualized training desired; (3) families felt prepared to go home, but transition was difficult; (4) home nursing care fraught with difficulty and yet essential for families of CWT. Families of CWT have specific needs related to discharge training, resources, support, and home nursing. Provider understanding of caregiver needs is essential for child well-being, patient-/family-centered care, and may improve health outcomes.

Care Coordination for Children and Youth With Special Health Care Needs: National Survey Results.

We analyzed findings from the 2009-2010 National Survey of Children with Special Health Care Needs to identify associations between families with children and youth with special health care needs (CYSHCN) reporting adequate care coordination (CC) with family-provider relations, shared decision making (SDM), and child outcomes. Eligible subjects were the 98% of families asked about CC, service use, and communication. Bivariate analysis using χ2 tests were performed on binary outcome variables to determine the strength of the associations between CC and independent and dependent variables. Weighted, multivariate logistic regression models were constructed to assess independent associations of adequate CC with child outcomes and associations of SDM on adequate CC. Among families of CYSHCN asked about CC, 72% reported receiving help with CC. Of these, 55% reported receiving adequate CC. Family report of adequate CC was favorably associated with family-provider relations, child outcomes, and report of provider participation in SDM.
