James-Stein for the leading eigenvector.

Recent research identifies and corrects bias, such as excess dispersion, in the leading sample eigenvector of a factor-based covariance matrix estimated from a high-dimension low sample size (HL) data set. We show that eigenvector bias can have a substantial impact on variance-minimizing optimization in the HL regime, while bias in estimated eigenvalues may have little effect. We describe a data-driven eigenvector shrinkage estimator in the HL regime called "James-Stein for eigenvectors" (JSE) and its close relationship with the James-Stein (JS) estimator for a collection of averages. We show, both theoretically and with numerical experiments, that, for certain variance-minimizing problems of practical importance, efforts to correct eigenvalues have little value in comparison to the JSE correction of the leading eigenvector. When certain extra information is present, JSE is a consistent estimator of the leading eigenvector.

A synthesis of pathways linking diet, metabolic risk and cardiovascular disease: a framework to guide further research and approaches to evidence-based practice.

Cardiovascular disease (CVD) is the most common non-communicable disease occurring globally. Although previous literature has provided useful insights into the important role that diet plays in CVD prevention and treatment, understanding the causal role of diets is a difficult task considering inherent and introduced weaknesses of observational (e.g. not properly addressing confounders and mediators) and experimental research designs (e.g. not appropriate or well designed). In this narrative review, we organised current evidence linking diet, as well as conventional and emerging physiological risk factors, with CVD risk, incidence and mortality in a series of diagrams. The diagrams presented can aid causal inference studies as they provide a visual representation of the types of studies underlying the associations between potential risk markers/factors for CVD. This may facilitate the selection of variables to be considered and the creation of analytical models. Evidence depicted in the diagrams was systematically collected from studies included in the British Nutrition Task Force report on diet and CVD and database searches, including Medline and Embase. Although several markers and disorders linked to conventional and emerging risk factors for CVD were identified, the causal link between many remains unknown. There is a need to address the multifactorial nature of CVD and the complex interplay between conventional and emerging risk factors with natural and built environments, while bringing the life course into the spotlight.

Paternal nicotine enhances fear memory, reduces nicotine administration, and alters hippocampal genetic and neural function in offspring.

Nicotine use remains highly prevalent with tobacco and e-cigarette products consumed worldwide. However, increasing evidence of transgenerational epigenetic inheritance suggests that nicotine use may alter behavior and neurobiology in subsequent generations. We tested the effects of chronic paternal nicotine exposure in C57BL6/J mice on fear conditioning in F1 and F2 offspring, as well as conditioned fear extinction and spontaneous recovery, nicotine self-administration, hippocampal cholinergic functioning, RNA expression, and DNA methylation in F1 offspring. Paternal nicotine exposure was associated with enhanced contextual and cued fear conditioning and spontaneous recovery of extinguished fear memories. Further, nicotine reinforcement was reduced in nicotine-sired mice, as assessed in a self-administration paradigm. These behavioral phenotypes were coupled with altered response to nicotine, upregulated hippocampal nicotinic acetylcholine receptor binding, reduced evoked hippocampal cholinergic currents, and altered methylation and expression of hippocampal genes related to neural development and plasticity. Gene expression analysis suggests multigenerational effects on broader gene networks potentially involved in neuroplasticity and mental disorders. The changes in fear conditioning similarly suggest phenotypes analogous to anxiety disorders similar to post-traumatic stress.

Lefamulin efficacy and safety in a pooled phase 3 clinical trial population with community-acquired bacterial pneumonia and common clinical comorbidities.

BACKGROUND: Lefamulin, a first-in-class pleuromutilin antibiotic approved for intravenous and oral use in adults with community-acquired bacterial pneumonia (CABP), was noninferior to moxifloxacin in the Lefamulin Evaluation Against Pneumonia (LEAP) 1 intravenous-to-oral switch study and the LEAP 2 oral-only study. Using pooled LEAP 1/2 data, we examined lefamulin efficacy/safety overall and within subgroups of patients presenting with comorbidities typical in CABP management. METHODS: In LEAP 1, adults with CABP were randomized to receive intravenous lefamulin (150 mg every 12 h) for 5‒7 days or moxifloxacin (400 mg every 24 h) for 7 days, with optional intravenous-to-oral switch if predefined improvement criteria were met. In LEAP 2, adults with CABP were randomized to receive oral lefamulin (600 mg every 12 h) for 5 days or moxifloxacin (400 mg every 24 h) for 7 days. Both studies assessed early clinical response (ECR) at 96 ± 24 h after first study drug dose and investigator assessment of clinical response (IACR) at test-of-cure (5‒10 days after last dose). Pooled analyses of the overall population used a 10% noninferiority margin. RESULTS: Lefamulin (n = 646) was noninferior to moxifloxacin (n = 643) for ECR (89.3% vs 90.5%, respectively; difference - 1.1%; 95% CI - 4.4 to 2.2); IACR success rates at test-of-cure were similarly high (≥ 85.0%). High efficacy with both lefamulin and moxifloxacin was also demonstrated across all well-represented patient subgroups, including those with advanced age, diabetes mellitus, a history of cardiovascular diseases (e.g., hypertension, congestive heart failure, or arrhythmia) or chronic lung diseases (e.g., asthma or chronic obstructive pulmonary disease), elevated liver enzymes, or mild-to-moderate renal dysfunction. No new safety signals were identified. CONCLUSIONS: Lefamulin may provide a valuable intravenous/oral monotherapy alternative to fluoroquinolones or macrolides for empiric treatment of patients with CABP, including cases of patients at risk for poor outcomes due to age or various comorbidities. TRIAL REGISTRATION: ClinicalTrials.gov LEAP 1 (NCT02559310; Registration Date: 24/09/2015) and LEAP 2 (NCT02813694; Registration Date: 27/06/2016).

Compassionate Bodies, Compassionate Practice: Navigating Body Image Tensions among Gay Men.

Our purpose in writing this Perspective in Practice is to create awareness about the role of compassion within dietetic practice, particularly the role of compassion for body image tensions. Nine self-identifying gay men were recruited to a photovoice research study that explored their beliefs, values, and practices relating to food and their bodies. Compassion was found as one way to navigate body images tensions. It is not the intent of this article to review all aspects of this research study but to use it as an example to illustrate compassion in dietetics. We suggest that our findings reveal the strength of using compassionate practice within the dietetic profession. In doing so, we call upon dietitians to incorporate compassion into their clinical and client care practices to foster health and healing for all communities, especially among those who struggle with body image tensions.

Efficacy and Safety of Intravenous-to-oral Lefamulin, a Pleuromutilin Antibiotic, for the Treatment of Community-acquired Bacterial Pneumonia: The Phase III Lefamulin Evaluation Against Pneumonia (LEAP 1) Trial.

BACKGROUND: Lefamulin, a pleuromutilin antibiotic, is active against pathogens commonly causing community-acquired bacterial pneumonia (CABP). The Lefamulin Evaluation Against Pneumonia (LEAP 1) study was a global noninferiority trial to evaluate the efficacy and safety of lefamulin for the treatment of CABP. METHODS: In this double-blind study, adults with CABP of Pneumonia Outcomes Research Team risk class ≥III were randomized 1:1 to receive lefamulin at 150 mg intravenously (IV) every 12 hours or moxifloxacin at 400 mg IV every 24 hours. After 6 doses, patients could be switched to an oral study drug if prespecified improvement criteria were met. If methicillin-resistant Staphylococcus aureus was suspected, either linezolid or placebo was added to moxifloxacin or lefamulin, respectively. The US Food and Drug Administration primary endpoint was an early clinical response (ECR) 96 ± 24 hours after the first dose of the study drug in the intent-to-treat (ITT) population (noninferiority margin, 12.5%). The European Medicines Agency co-primary endpoints were an investigator assessment of clinical response (IACR) 5-10 days after the last dose of the study drug in the modified ITT (mITT) and clinically evaluable (CE) populations (noninferiority margin, 10%). RESULTS: There were 551 patients randomized (n = 276 lefamulin; n = 275 moxifloxacin). Lefamulin was noninferior to moxifloxacin for ECR (87.3% vs 90.2%, respectively; difference -2.9%, 95% confidence interval [CI] g -8.5 to 2.8) and IACR (mITT, 81.7% vs 84.2%, respectively; difference -2.6%, 95% CI -8.9 to 3.9; CE, 86.9% vs 89.4%, respectively; difference -2.5%, 95% CI -8.4 to 3.4). Rates of study drug discontinuation due to treatment-emergent adverse events were 2.9% for lefamulin and 4.4% for moxifloxacin. CONCLUSIONS: Lefamulin was noninferior to moxifloxacin for the primary efficacy endpoints and was generally safe and well tolerated. CLINICAL TRIALS REGISTRATION: NCT02559310.

C57BL/6 substrain differences in inflammatory and neuropathic nociception and genetic mapping of a major quantitative trait locus underlying acute thermal nociception.

Sensitivity to different pain modalities has a genetic basis that remains largely unknown. Employing closely related inbred mouse substrains can facilitate gene mapping of nociceptive behaviors in preclinical pain models. We previously reported enhanced sensitivity to acute thermal nociception in C57BL/6J (B6J) versus C57BL/6N (B6N) substrains. Here, we expanded on nociceptive phenotypes and observed an increase in formalin-induced inflammatory nociceptive behaviors and paw diameter in B6J versus B6N mice (Charles River Laboratories). No strain differences were observed in mechanical or thermal hypersensitivity or in edema following the Complete Freund's Adjuvant model of inflammatory pain, indicating specificity in the inflammatory nociceptive stimulus. In the chronic constrictive nerve injury, a model of neuropathic pain, no strain differences were observed in baseline mechanical threshold or in mechanical hypersensitivity up to one month post-chronic constrictive nerve injury. We replicated the enhanced thermal nociception in the 52.5°C hot plate test in B6J versus B6N mice from The Jackson Laboratory. Using a B6J × B6N-F2 cross (N = 164), we mapped a major quantitative trait locus underlying hot plate sensitivity to chromosome 7 that peaked at 26 Mb (log of the odds [LOD] = 3.81, p < 0.01; 8.74 Mb-36.50 Mb) that was more pronounced in males. Genes containing expression quantitative trait loci associated with the peak nociceptive marker that are implicated in pain and inflammation include Ryr1, Cyp2a5, Pou2f2, Clip3, Sirt2, Actn4, and Ltbp4 (false discovery rate < 0.05). Future studies involving positional cloning and gene editing will determine the quantitative trait gene(s) and potential pleiotropy of this locus across pain modalities.

Multigenerational and transgenerational effects of paternal exposure to drugs of abuse on behavioral and neural function.

Addictions are highly heritable disorders, with heritability estimates ranging from 39% to 72%. Multiple studies suggest a link between paternal drug abuse and addiction in their children. However, patterns of inheritance cannot be explained purely by Mendelian genetic mechanisms. Exposure to drugs of abuse results in epigenetic changes that may be passed on through the germline. This mechanism of epigenetic transgenerational inheritance may provide a link between paternal drug exposure and addiction susceptibility in the offspring. Recent studies have begun to investigate the effect of paternal drug exposure on behavioral and neurobiological phenotypes in offspring of drug-exposed fathers in rodent models. This review aims to discuss behavioral and neural effects of paternal exposure to alcohol, cocaine, opioids, and nicotine. Although a special focus will be on addiction-relevant behaviors, additional behavioral effects including cognition, anxiety, and depressive-like behaviors will be discussed.

Mechanistic basis of an epistatic interaction reducing age at onset in hereditary spastic paraplegia.

Many genetic neurological disorders exhibit variable expression within affected families, often exemplified by variations in disease age at onset. Epistatic effects (i.e. effects of modifier genes on the disease gene) may underlie this variation, but the mechanistic basis for such epistatic interactions is rarely understood. Here we report a novel epistatic interaction between SPAST and the contiguous gene DPY30, which modifies age at onset in hereditary spastic paraplegia, a genetic axonopathy. We found that patients with hereditary spastic paraplegia caused by genomic deletions of SPAST that extended into DPY30 had a significantly younger age at onset. We show that, like spastin, the protein encoded by SPAST, the DPY30 protein controls endosomal tubule fission, traffic of mannose 6-phosphate receptors from endosomes to the Golgi, and lysosomal ultrastructural morphology. We propose that additive effects on this pathway explain the reduced age at onset of hereditary spastic paraplegia in patients who are haploinsufficient for both genes.

Oral Lefamulin vs Moxifloxacin for Early Clinical Response Among Adults With Community-Acquired Bacterial Pneumonia: The LEAP 2 Randomized Clinical Trial.

IMPORTANCE: New antibacterials are needed to treat community-acquired bacterial pneumonia (CABP) because of growing antibacterial resistance and safety concerns with standard care. OBJECTIVE: To evaluate the efficacy and adverse events of a 5-day oral lefamulin regimen in patients with CABP. DESIGN, SETTING, AND PARTICIPANTS: A phase 3, noninferiority randomized clinical trial conducted at 99 sites in 19 countries that included adults aged 18 years or older with a Pneumonia Outcomes Research Team (PORT) risk class of II, III, or IV; radiographically documented pneumonia; acute illness; 3 or more CABP symptoms; and 2 or more vital sign abnormalities. The first patient visit was on August 30, 2016, and patients were followed up for 30 days; the final follow-up visit was on January 2, 2018. INTERVENTIONS: Patients were randomized 1:1 to receive oral lefamulin (600 mg every 12 hours for 5 days; n = 370) or moxifloxacin (400 mg every 24 hours for 7 days; n = 368). MAIN OUTCOMES AND MEASURES: The US Food and Drug Administration (FDA) primary end point was early clinical response at 96 hours (within a 24-hour window) after the first dose of either study drug in the intent-to-treat (ITT) population (all randomized patients). Responders were defined as alive, showing improvement in 2 or more of the 4 CABP symptoms, having no worsening of any CABP symptoms, and not receiving any nonstudy antibacterial drug for current CABP episode. The European Medicines Agency coprimary end points (FDA secondary end points) were investigator assessment of clinical response at test of cure (5-10 days after last dose) in the modified ITT population and in the clinically evaluable population. The noninferiority margin was 10% for early clinical response and investigator assessment of clinical response. RESULTS: Among 738 randomized patients (mean age, 57.5 years; 351 women [47.6%]; 360 had a PORT risk class of III or IV [48.8%]), 707 (95.8%) completed the trial. Early clinical response rates were 90.8% with lefamulin and 90.8% with moxifloxacin (difference, 0.1% [1-sided 97.5% CI, -4.4% to ∞]). Rates of investigator assessment of clinical response success were 87.5% with lefamulin and 89.1% with moxifloxacin in the modified ITT population (difference, -1.6% [1-sided 97.5% CI, -6.3% to ∞]) and 89.7% and 93.6%, respectively, in the clinically evaluable population (difference, -3.9% [1-sided 97.5% CI, -8.2% to ∞]) at test of cure. The most frequently reported treatment-emergent adverse events were gastrointestinal (diarrhea: 45/368 [12.2%] in lefamulin group and 4/368 [1.1%] in moxifloxacin group; nausea: 19/368 [5.2%] in lefamulin group and 7/368 [1.9%] in moxifloxacin group). CONCLUSIONS AND RELEVANCE: Among patients with CABP, 5-day oral lefamulin was noninferior to 7-day oral moxifloxacin with respect to early clinical response at 96 hours after first dose. TRIAL REGISTRATIONS: ClinicalTrials.gov Identifier: NCT02813694; European Clinical Trials Identifier: 2015-004782-92.

A nonstop variant in REEP1 causes peripheral neuropathy by unmasking a 3'UTR-encoded, aggregation-inducing motif.

Single-nucleotide variants that abolish the stop codon ("nonstop" alterations) are a unique type of substitution in genomic DNA. Whether they confer instability of the mutant mRNA or result in expression of a C-terminally extended protein depends on the absence or presence of a downstream in-frame stop codon, respectively. Of the predicted protein extensions, only few have been functionally characterized. In a family with autosomal dominant Charcot-Marie-Tooth disease type 2, that is, an axonopathy affecting sensory neurons as well as lower motor neurons, we identified a heterozygous nonstop variant in REEP1. Mutations in this gene have classically been associated with the upper motor neuron disorder hereditary spastic paraplegia (HSP). We show that the C-terminal extension resulting from the nonstop variant triggers self-aggregation of REEP1 and of several reporters. Our findings support the recently proposed concept of 3'UTR-encoded "cryptic amyloidogenic elements." Together with a previous report on an aggregation-prone REEP1 deletion variant in distal hereditary motor neuropathy, they also suggest that toxic gain of REEP1 function, rather than loss-of-function as relevant for HSP, specifically affects lower motor neurons. A search for similar correlations between genotype, phenotype, and effect of mutant protein may help to explain the wide clinical spectra also in other genetically determined disorders.

eHealth versus equity: Using a feminist poststructural framework to explore the influence of perinatal eHealth resources on health equity.

AIMS AND OBJECTIVES: To explore whether and how eHealth resources targeted to families during the perinatal period effectively reach a diverse population or further oppress marginalised groups. BACKGROUND: eHealth is often intended to reach a broad population, thus health content must be relatively generalised which limits the ability to tailor health education and interventions to individual needs. Generalisation of health information has historically represented a hegemonic depiction of the health consumer, especially within the perinatal period, often disregarding the diversity that exists in the world and perpetuating heteronormative constructs within healthcare systems as a result. DESIGN: A critical review of the literature regarding perinatal eHealth resources was conducted using a feminist poststructuralist approach for analysis. Included literature addresses the development, implementation and/or evaluation of perinatal eHealth resources. DISCUSSION: This approach uncovered hegemonic discourses related to the current state of perinatal eHealth resources. Nurses and midwives have the unique advantage of interacting and understanding diverse populations. Thus, nurses and midwives are integral to the development, implementation and evaluation of eHealth resources to reduce social health inequity. RELEVANCE TO CLINICAL PRACTICE: This paper acts as an exemplar on how to apply feminist poststructuralism to highlight inequities that exist and identifies strategies for nurses and midwives to become involved in the development of eHealth resources or advocate for greater visibility within current resources.

Understanding the invisibility of black nurse leaders using a black feminist poststructuralist framework.

AIM: This paper explores the invisibility and underrepresentation of Black nurses in formal and informal leadership roles using a Black feminist poststructuralist framework. The paper describes historical and contemporary challenges experienced by Black nurses throughout their nursing education and in practice. It also highlights how social and institutional discourses continue to marginalise and oppress Black nurses as leaders and render them invisible. BACKGROUND: Diversity among nursing leaders is essential to inform health care delivery, develop inclusive practices and provide culturally sensitive care. Despite this glaring need for diversity within nursing in Canada, there remains a significant underrepresentation of Black nurses in the workforce and as leaders. DESIGN: This is a discursive paper on Black nurses in nursing education and the workforce as well as their location as leaders in health care through a critical analysis using Black feminist poststructuralism. METHODS: A review of the literature involved searching electronic databases CINAHL, NovaNet, PubMed and Google Scholar using keywords including: Black; African; Nurses; Leaders; Feminism; Poststructural. Articles were screened by titles and abstracts before accessing full-text for relevant articles. RESULTS: Black feminist poststructuralism uncovers how power, language, subjectivity and agency are constructed by the historically ingrained social and institutional discourses of everyday life for Black nurses. Experiences of discrimination and oppression were common throughout nursing education and practice for Black nurses, resulting in feelings of marginalisation and isolation. CONCLUSION: The invisibility of Black nurse leaders is the result of generational oppression and discrimination manifested through discourses. Systemic, institutional and historical discourses perpetuate barriers for Black nurse leaders, resulting in their invisibility or absence in practice. RELEVANCE TO CLINICAL PRACTICE: This paper is designed to generate discussion related to the invisibility of Black nurse leaders by providing an understanding of the historical experiences of Black people, their entry into the nursing profession and the present day challenges they face. This discussion will inform health care practice, policy, and structuring by identifying the barriers to leadership for Black nurses.

Accessing new understandings of trauma-informed care with queer birthing women in a rural context.

AIMS AND OBJECTIVES: Participant narratives from a feminist and queer phenomenological study aim to broaden current understandings of trauma. Examining structural marginalisation within perinatal care relationships provides insights into the impact of dominant models of care on queer birthing women. More specifically, validation of queer experience as a key finding from the study offers trauma-informed strategies that reconstruct formerly disempowering perinatal relationships. BACKGROUND: Heteronormativity governs birthing spaces and presents considerable challenges for queer birthing women who may also have an increased risk of trauma due to structurally marginalising processes that create and maintain socially constructed differences. DESIGN: Analysis of the qualitative data was guided by feminist and queer phenomenology. This was well suited to understanding queer women's storied narratives of trauma, including disempowering processes of structural marginalisation. METHODS: Semistructured and conversational interviews were conducted with a purposeful sample of thirteen queer-identified women who had experiences of birthing in rural Nova Scotia, Canada. RESULTS: Validation was identified as meaningful for queer women in the context of perinatal care in rural Nova Scotia. Offering new perspectives on traditional models of assessment provide strategies to create a context of care that reconstructs the birthing space insofar as women at risk do not have to come out as queer in opposition to the expectation of heterosexuality. CONCLUSIONS: Normative practices were found to further the effects of structural marginalisation suggesting that perinatal care providers, including nurses, can challenge dominant models of care and reconstruct the relationality between queer women and formerly disempowering expectations of heteronormativity that govern birthing spaces. RELEVANCE TO CLINICAL PRACTICE: New trauma-informed assessment strategies reconstruct the relationality within historically disempowering perinatal relationships through potentiating difference which avoids retraumatising women with re-experiencing the process of coming out as queer in opposition to the expectation of heterosexuality.

Appendicitis in the Infant Population: A Case Report and Review of a Four-Month Old With Appendicitis.

BACKGROUND: Appendicitis is uncommon in children <6 months old, with few observational studies reporting cases of children younger than 5 years old with the diagnosis. The classic periumbilical pain that migrates to the right lower quadrant, followed by the onset of fever and vomiting, is present in approximately 40% of pediatric patients under 12 years of age with appendicitis. CASE REPORT: A 4-month-old girl presented to the Emergency Department (ED) with acute onset of grunting, pallor, fussiness, emesis, and diarrhea. The patient was initially afebrile, tachycardic, and tachypneic with a soft, nondistended, nontender abdomen and active bowel sounds. The patient became febrile, with a maximum temperature of 39.3°C (102.7°F), and remained tachycardic despite receiving fluids and antipyretics. Laboratory studies were notable for mild dehydration and sterile pyuria. Chest x-ray study was negative for infectious etiologies. Initial abdominal ultrasound found no clear etiology of the patient's symptoms. The patient was admitted to inpatient pediatrics for dehydration, fever, and presumed pyelonephritis. Twenty-four hours later the patient's abdomen became distended and diffusely tender to palpation, with obstipation and increasing episodes of emesis. Abdominal x-ray study demonstrated mild gaseous distension of multiple bowel loops with repeat abdominal ultrasound notable for a focal 8-mm, noncompressible hyperemic structure in the right lower quadrant. The patient was taken to the operating room for a laparoscopic appendectomy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Appendicitis is a potentially life-threatening condition. In the infant population it frequently presents without the features typically seen in older children.

The application of a feminist poststructural framework in nursing practice for addressing young women's sexual health.

AIMS AND OBJECTIVES: Using a feminist poststructuralist framework, this paper examines the conflicting discourses of young women who experience power struggles with regard to their sexuality and sexual health practices. It aims to provide nurses with a pragmatic framework for exploring, interrogating and potentially transforming health care situations when caring for young women in a sexual health setting. BACKGROUND: Sexuality and sexual health are important components of health and well-being. Young men and women are continually perpetuated with societal ideals of sexuality and sexual health practices. Young women specifically, receive societal and peer pressure to conform to certain sexual health practices that can lead to both positive and negative health outcomes. Nurses and other health care providers may care for young women in a public or acute care setting that are living with these conflicting sexual health discourses. DESIGN: A review of the literature on young women's sexuality and sexual health was conducted and analysed using a feminist poststructuralist framework. METHODS: A review of the sexual health literature on young women was conducted. Issues identified from the review, as they relate to sexual discourse were power, language, subjectivity and agency. Nursing strategies to address these issues in practice were identified using a feminist poststructuralist framework. DISCUSSION: The feminist poststructural framework highlights the conflicting discourses related to young women's sexuality and sexual health practices. This paper provides a pragmatic example of how to incorporate theory to improve nurses' understanding of an individual or group's health. RELEVANCE TO CLINICAL PRACTICE: Examples of how a feminist poststructural framework can be used to enhance sexual health nursing practice are discussed, such as helping nurses to challenge the status quo and question the sexual health norms among young women.

A national survey on health department capacity for community engagement in emergency preparedness.

CONTEXT: Limited systematic knowledge exists about how public health practitioners and policy makers can best strengthen community engagement in public health emergency preparedness ("CE-PHEP"), a top priority for US national health security. OBJECTIVES: To investigate local health department (LHD) adoption of federally recommended participatory approaches to PHEP and to identify LHD organizational characteristics associated with more intense CE-PHEP. DESIGN: National survey in 2012 of LHDs using a self-administered Web-based questionnaire regarding LHD practices and resources for CE-PHEP ("The Community Engagement for Public Health Emergency Preparedness Survey"). Differences in survey responses were examined, and a multivariate analysis was used to test whether LHD organizational characteristics were associated with differences in CE-PHEP intensity. SETTING: A randomized sample of 754 LHDs drawn from the 2565 LHDs that had been invited to participate in the 2010 National Profile of LHDs. Sample selection was stratified by the size of population served and geographic location. PARTICIPANTS: Emergency preparedness coordinators reporting on their respective LHDs. MAIN OUTCOME MEASURE: CE-PHEP intensity as measured with a scoring system that rated specific CE-PHEP practices by LHD according to the relative degrees of public participation and community capacity they represented. RESULTS: Survey response rate was 61%. The most common reported CE-PHEP activity was disseminating personal preparedness materials (90%); the least common was convening public forums on PHEP planning (22%). LHD characteristics most strongly associated with more intense CE-PHEP were having a formal CE-PHEP policy, allocating funds for CE-PHEP, having strong support from community-based organizations, and employing a coordinator with prior CE experience. CONCLUSIONS: Promising ways to engage community partners more fully in the PHEP enterprise are institutionalizing CE-PHEP objectives, employing sufficient and skilled staff, leveraging current community-based organization support, and aligning budgets with the value of CE-PHEP to US national health security.

Factors associated with uptake of the Influenza A(H1N1)pdm09 monovalent pandemic vaccine in K-12 Public Schools, Maine 2009-2010.

CONTEXT AND OBJECTIVE: Maine implemented a statewide pre-K through 12-school vaccination program during the 2009-2010 H1N1 influenza pandemic. The main objective of this study was to determine which school, nurse, consent form, and clinic factors were associated with school-level vaccination rates for the first dose of the 2009 H1N1 pandemic vaccine. METHODS: In April 2010, school nurses or contacts were e-mailed electronic surveys. Generalized linear mixed regression was used to predict adjusted vaccination rates using random effects to account for correlations within school districts. Elementary and secondary (middle and high) schools were analyzed separately. RESULTS: Of 645 schools invited to participate, 82% (n = 531) completed the survey. After excluding schools that were ineligible or could not provide outcome data, data for 256 elementary and 124 secondary public schools were analyzed and included in the multivariable analyses. The overall, unadjusted, vaccination rate was 51% for elementary schools and 45% for secondary schools. Elementary schools that had 50 or fewer students per grade, had availability of additional nursing staff, which did not require parental presence at the H1N1 clinic or disseminated consent forms by mail and backpack (compared with backpack only) had statistically significant (P < .05) higher (adjusted) vaccination rates. For secondary schools, the vaccination rate for schools with the lowest proportion of students receiving subsidized lunch (ie, highest socioeconomic status) was 58% compared with 37% (P < .001) for schools with the highest proportion receiving subsidized lunch. CONCLUSIONS: Several factors were independently associated with vaccination rates. For elementary schools, planners should consider strategies such as providing additional nursing staff and disseminating consent forms via multiple methods. The impact of additional factors, including communication approaches and parent and student attitudes, needs to be investigated, especially for secondary schools.
