Missed Screening Mammography Appointments: Patient Sociodemographic Characteristics and Mammography Completion After 1 Year.

OBJECTIVE: Patients who miss screening mammogram appointments without notifying the health care system (no-show) risk care delays. We investigate sociodemographic characteristics of patients who experience screening mammogram no-shows at a community health center and whether and when the missed examinations are completed. METHODS: We included patients with screening mammogram appointments at a community health center between January 1, 2021, and December 31, 2021. Language, race, ethnicity, insurance type, residential ZIP code tabulation area (ZCTA) poverty, appointment outcome (no-show, same-day cancelation, completed), and dates of completed screening mammograms after no-show appointments with ≥1-year follow-up were collected. Multivariable analyses were used to assess associations between patient characteristics and appointment outcomes. RESULTS: Of 6,159 patients, 12.1% (743 of 6,159) experienced no-shows. The no-show group differed from the completed group by language, race and ethnicity, insurance type, and poverty level (all P < .05). Patients with no-shows more often had: primary language other than English (32.0% [238 of 743] versus 26.7% [1,265 of 4,741]), race and ethnicity other than White non-Hispanic (42.3% [314 of 743] versus 33.6% [1,595 of 4,742]), Medicaid or means-tested insurance (62.0% [461 of 743] versus 34.4% [1,629 of 4,742]), and residential ZCTAs with ≥20% poverty (19.5% [145 of 743] versus 14.1% [670 of 4,742]). Independent predictors of no-shows were Black non-Hispanic race and ethnicity (adjusted odds ratio [aOR], 1.52; 95% confidence interval [CI], 1.12-2.07; P = .007), Medicaid or other means-tested insurance (aOR, 2.75; 95% CI, 2.29-3.30; P < .001), and ZCTAs with ≥20% poverty (aOR, 1.76; 95% CI, 1.14-2.72; P = .011). At 1-year follow-up, 40.6% (302 of 743) of patients with no-shows had not completed screening mammogram. DISCUSSION: Screening mammogram no-shows is a health equity issue in which socio-economically disadvantaged and racially and ethnically minoritized patients are more likely to experience missed appointments and continued delays in screening mammogram completion.

Network structure of avian mixed-species flocks decays with elevation and latitude across the Andes.

Birds in mixed-species flocks benefit from greater foraging efficiency and reduced predation, but also face costs related to competition and activity matching. Because this cost-benefit trade-off is context-dependent (e.g. abiotic conditions and habitat quality), the structure of flocks is expected to vary along elevational, latitudinal and disturbance gradients. Specifically, we predicted that the connectivity and cohesion of flocking networks would (i) decline towards tropical latitudes and lower elevations, where competition and activity matching costs are higher, and (ii) increase with lower forest cover and greater human disturbance. We analysed the structure of 84 flock networks across the Andes and assessed the effect of elevation, latitude, forest cover and human disturbance on network characteristics. We found that Andean flocks are overall open-membership systems (unstructured), though the extent of network structure varied across gradients. Elevation was the main predictor of structure, with more connected and less modular flocks upslope. As expected, flocks in areas with higher forest cover were less cohesive, with better defined flock subtypes. Flocks also varied across latitude and disturbance gradients as predicted, but effect sizes were small. Our findings indicate that the unstructured nature of Andean flocks might arise as a strategy to cope with harsh environmental conditions. This article is part of the theme issue 'Mixed-species groups and aggregations: shaping ecological and behavioural patterns and processes'.

A scoping review on the nurse scientist role within healthcare systems.

BACKGROUND: The role of the nurse scientist in the clinical setting is not well defined, which contributes to variability in role implementation, scope, administration, funding, and affiliation across healthcare sites. AIMS: The aim of this scoping review was to identify attributes of the clinical nurse scientist role and its operationalization in the clinical setting through available evidence. METHODS: A comprehensive, computerized search of the literature in PubMed, Medline, and CINAHL was conducted in early May 2020 by a medical research librarian and repeated in July 2021 and April 2022. The 5-step framework described by Arskey and O'Malley guided the review methodology. Two reviewers conducted an independent screen of all articles, followed by a full-text review of eligible articles by two independent reviewers each using a standardized data extraction template. Themes were then organized and synthesized using descriptive content analysis from the included articles. RESULTS: A final sample of 55 full-text articles were included in the review. Overall, the findings suggest that the nurse scientist role in a clinical setting can be challenging to implement in complex healthcare environments. Successful models include the nurse scientist in a leadership role, alignment of research with institutional priorities, and strong support from senior leadership. LINKING EVIDENCE TO ACTION: Findings suggest that standardized guidelines are lacking to govern the implementation of the nurse scientist role in the clinical setting. To succeed, the nurse scientist role must be valued and supported by organizational leaders. Further, access to resources to build infrastructure must be provided. The magnitude and scope of individual organizational support can be tailored based on the resources of the institution; however, the foundation of having institutional leadership support is critical to role success of the clinical nurse researcher.

Nurse-sensitive indicators during COVID-19.

PURPOSE: Nurses are on the forefront of delivering care to patients hospitalized with COVID-19. Nurses' impact on patient care can be discerned through assessment and documentation strategies, including structured and unstructured narratives, clinical pathways, flowsheets, and problem-based approaches. To date, there are no published reports regarding nursing assessment and documentation during the COVID-19 pandemic using an assessment framework to capture clinical decision making, nursing diagnoses, and key social determinant of health (SDoH) data. Hence, the purpose of this investigation was to conduct an exploratory nursing documentation audit of patients hospitalized with COVID-19 during the first surge to identify types and frequency of nurse-sensitive indicators, including SDoH. METHOD: This pilot study utilized a retrospective chart review design at a single academic medical center, utilizing Gordon's Eleven Functional Health Patterns (FHP) framework to extract clinical, social, and nursing assessment data for patients hospitalized with COVID-19. Descriptive statistics were computed for continuous variables and counts/percentages for categorical variables. FINDINGS: Data from 94 patient records were analyzed. Most patients were male (59.6%), with a mean age of 58 years. Nearly 15% of patients were Black and 12.8% were Hispanic, most residing in four geographic areas. Nine of the 11 FHPs were reflected in nurse-sensitive indicators documented in the electronic health record. SDoH data were inconsistently documented, including race, education, history of neglect/abuse, and occupation. CONCLUSION: The FHP framework captured many nurse-sensitive indicators during the first COVID-19 surge, although screening for and documenting SDoH data were limited. IMPLICATIONS FOR NURSING PRACTICE: Findings can influence the development of nursing assessment and documentation during crisis care delivery that are inclusive of distinct sociodemographic factors, in addition to clinical factors, to provide comprehensive, culturally sensitive care. Such documentation will enhance the use of nursing knowledge guided by a nursing framework to make visible the essential contributions of nurses to healthcare delivery.

Comparative Immunogenicity and Effectiveness of mRNA-1273, BNT162b2, and Ad26.COV2.S COVID-19 Vaccines.

BACKGROUND: Understanding immunogenicity and effectiveness of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines is critical to guide rational use. METHODS: We compared the immunogenicity of mRNA-1273, BNT-162b2, and Ad26.COV2.S in healthy ambulatory adults. We performed an inverse-variance meta-analysis of population-level effectiveness from public health reports in > 40 million individuals. RESULTS: A single dose of either mRNA vaccine yielded comparable antibody and neutralization titers to convalescent individuals. Ad26.COV2.S yielded lower antibody concentrations and frequently undetectable neutralization titers. Bulk and cytotoxic T-cell responses were higher in mRNA1273 and BNT162b2 than Ad26.COV2.S recipients. Regardless of vaccine, <50% of vaccinees demonstrated CD8+ T-cell responses. Antibody concentrations and neutralization titers increased comparably after the first dose of either vaccine, and further in recipients of a second dose. Prior infection was associated with high antibody concentrations and neutralization even after a single dose and regardless of vaccine. Neutralization of Beta, Gamma, and Delta strains were poorer regardless of vaccine. In meta-analysis, relative to mRNA1273 the effectiveness of BNT162b2 was lower against infection and hospitalization, and Ad26COV2.S was lower against infection, hospitalization, and death. CONCLUSIONS: Variation in the immunogenicity correlates with variable effectiveness of the 3 vaccines deployed in the United States.

Comparative immunogenicity and effectiveness of mRNA-1273, BNT162b2 and Ad26.COV2.S COVID-19 vaccines.

BACKGROUND: Understanding immunogenicity and effectiveness of SARS-CoV-2 vaccines is critical to guide rational use. METHODS: We compared the immunogenicity of mRNA-1273, BNT-162b2 or Ad26.COV2.S in ambulatory adults in Massachusetts, USA. To correlate immunogenicity with effectiveness of the three vaccines, we performed an inverse-variance meta-analysis of population level effectiveness from public health reports in >40 million individuals. RESULTS: A single dose of either mRNA vaccine yielded comparable antibody and neutralization titers to convalescent individuals. Ad26.COV2.S yielded lower antibody concentrations and frequently negative neutralization titers. Bulk and cytotoxic T-cell responses were higher in mRNA1273 and BNT162b2 than Ad26.COV2.S recipients, and <50% of vaccinees demonstrate CD8+ T-cell responses to spike peptides. Antibody concentrations and neutralization titers increased comparably after the first dose of either vaccine, and further in recipients of a second dose. Prior infection was associated with high antibody concentrations and neutralization even after a single dose and regardless of vaccine. Neutralization of beta, gamma and delta strains were poorer regardless of vaccine. Relative to mRNA1273, the effectiveness of BNT162b2 was lower against infection and hospitalization; and Ad26COV2.S was lower against infection, hospitalization and death. CONCLUSIONS: Variation in the immunogenicity correlates with variable effectiveness of the three FDA EUA vaccines deployed in the USA.

Dihydroergotamine infusion for pediatric refractory headache: A retrospective chart review.

BACKGROUND: Headaches are a common symptom in children. Children with refractory headaches may be admitted for inpatient treatment with intravenous dihydroergotamine mesylate (DHE). However, very few studies have characterized these patients and their treatment outcomes using validated, self-reported, pain scales. OBJECTIVE: The objective of this study was to describe demographic and clinical characteristics of children admitted for DHE infusion, determine DHE treatment outcomes by means of numeric pain scale ratings, and explore associations between treatment outcomes and clinical characteristics. METHODS: Retrospective chart review was completed in patients ages 5-21 admitted for DHE infusion from January 2013 to July 2018 at a large, pediatric academic medical center and community-based satellite center. All primary headache types were included. RESULTS: A total of 200 unique admissions for DHE were available for analysis. Overall, patients were predominantly White (87.5%, 175/200) and female (80.0%, 160/200) with an average age of 15.4 years (SD 2.3). Common comorbidities included obesity (42.0%, 81/193), anxiety (41.0%, 82/200), and depression (20.0%, 40/200). The mean length of stay was 2.4 days (SD 1.10; range 1-8 days). Most headaches (65.0%, 130/200) met the International Classification of Headache Disorders, 3rd edition criteria for migraine, followed by new daily persistent headache (25.5%, 51/200). Mean DHE maximum dose was 5.3 (SD 2.17; range 0.5-14.5 mg) with most patients requiring 3.5-6.5 mg. DHE was typically terminated at six doses (range 1-15). The most frequently reported adverse event was nausea (5.5%, 11/200). There was no difference in pain severity at admission across headache types, with an average baseline pain score of 8.1 (SD 1.6). Posttreatment reduction in pain score was statistically significant (range: -3.2 to -4.9; each p < 0.001) across all headache types. Overall, 84.0% (168/200) of the patients had some improvement in pain. More than half of the patients (53.5%, 107/200) showed at least moderate improvement (≥50.0% reduction in pain score), and 18.0% (36/200) had full headache resolution. Limited patients (16.0%, 32/200) experienced no improvement in pain. CONCLUSIONS: Treatment with DHE resulted in at least some improvement for most patients regardless of headache type or number of doses. Clinical trials stratified by headache type and comorbid factors could help clarify treatment algorithms to optimize patient outcomes.

Nudging Discharge Readiness With a Poster: A Sequential, Exploratory Mixed Methods Pilot Study of Patient Caregivers.

Many hospitals face a common challenge: limited space for a high number of patients. This has led to quick patient throughput, which can impact patient perception of discharge readiness. This study examined whether a poster highlighting tasks to complete as part of the discharge process improved caregiver perception of readiness to transition home. Using a sequential, exploratory mixed methods design, focus groups were convened to explore clinical staff perspective on the discharge process on 3 pediatric inpatient units at a large, urban, pediatric academic medical center in the United States. Analysis of this content informed the design of a poster intervention to "nudge" caregivers (eg, parents, legal guardians) toward readiness and self-efficacy that was then tested in a randomized, controlled experiment. The poster focused on practical knowledge for specific areas of transition adjustment, such as medication and care recipient recovery behaviors, barriers, and enablers. Caregivers (n = 135) completed surveys at discharge indicating their perceived readiness to transition home with their child. Analysis of covariance was used to test the effect of the poster condition (poster vs no poster) on caregiver readiness, preparedness, and confidence for discharge while controlling for previous admission history. Significant effects for poster presence were found on caregivers' perceived readiness for discharge, F 1,125 = 7.75, P = .006, Cohen's d = 0.44; and caregivers' perceived preparedness for the transition home, F 1,121 =7.24, P = .008, Cohen's d = 0.44. Only a marginal effect was found for poster condition on caregivers' confidence ratings, F 1,125 = 2.93, P = .090, Cohen's d = 0.29. The results suggest that simple nudges in the patient care environment may yield measurable improvements in caregiver outcomes.

Nurse-Led Call Back Program to Improve Patient Follow-Up With Providers After Discharge From the Emergency Department.

Phone calls to patients after discharge from the emergency department (ED) serve as reminders to schedule medical follow-up, support adherence to discharge instructions, and reduce revisits to already-crowded EDs. An existing, nurse-administered, call-back program contacted randomly selected ED patients 24 to 48 hours following discharge. This program did not improve patient follow-up (48.68%) nor reduce the ED revisit rate (6.7% baseline vs 6.0% postimplementation). Plan-Do-Study-Act methodology tested a modification to the existing program consisting of a second, scripted phone call from a trained volunteer at 72 to 96 hours postdischarge. Volunteers utilized a patient list and script, and nurses provided expertise to eliminate identified barriers to follow-up. Follow-up rate and ED revisit were monitored through the electronic medical record. A total of 894 patients participated between October 2017 and June 2018. Follow-up increased from 48.68% to 65.5% (P < .0001) and ED revisit decreased significantly (4.5% vs 8.6%, P < .001). This innovative nurse-led, systematic postdischarge call-back program utilizing hospital volunteers increased patient compliance with post-ED medical follow-up while significantly reducing the rate of patient revisit to the ED within 7 days of discharge.

Occupational contact dermatitis caused by opioids: A case series.

BACKGROUND: Opioid-manufacturing facility workers are at risk of developing occupational contact dermatitis. OBJECTIVES: To describe the causes of occupational allergic contact dermatitis caused by opioids in an opioid-manufacturing facility. MATERIALS AND METHODS: A retrospective review was performed of patients assessed at the Occupational Dermatology Clinic in Melbourne, Australia from 2004 to 2017. RESULTS: Fifteen workers from an opioid-manufacturing facility were assessed in our clinic over a period of 14 years. Of these, 11 individuals were diagnosed with occupational allergic contact dermatitis caused by opioids, with seven reacting to thebaine, five to morphine, four to norhydroxymorphinone, two to codeine, and two to oripavine. Two people were suspected of having immediate hypersensitivity reactions to opioids, including one who also had allergic contact dermatitis. Two patients were diagnosed with urticaria, aggravated at work. One patient was diagnosed with a non-occupational rash. CONCLUSIONS: We report a case series of workers with allergic contact dermatitis caused by opioids in a manufacturing facility. With greater awareness, including implementation of an educational programme and improved skin protection, the number of cases declined over time. Interestingly, norhydroxymorphinone had not been reported as an allergen before. Further testing is required to establish optimal patch test concentrations of all opiates.

Contact allergy and allergic contact dermatitis caused by lavender: A retrospective study from an Australian clinic.

BACKGROUND: Lavender is commonly used in aromatherapy and in a broad range of personal and household products. It has been identified as a contact sensitizer, and has been reported to cause allergic contact dermatitis (ACD). OBJECTIVES: To report our experience with contact allergy and ACD caused by lavender, and to raise awareness of lavender as a potential contact allergen. METHOD: A retrospective database review was performed of patients attending patch testing clinics at the Skin and Cancer Foundation, Victoria, Australia, from January 1, 1993 to December 31, 2017. RESULTS: Among the 2178 patients patch tested with lavender over this period, a total of 58 positive reactions were recorded in 49 individuals, giving a positive patch test prevalence for patients tested with lavender of 2.2%. Twenty-seven patients were diagnosed with ACD. The most common sources of exposure to lavender were personal care products and essential oils. Of the patients with ACD, 74% were tested with lavender absolute, with positive results in 90% of cases. CONCLUSION: Lavender is an uncommon cause of ACD but is important to consider, given the potential for exposure through the use of personal care items and essential oils.

How thyroid hormones and their inhibitors affect cartilage growth and shape in the frog Xenopus laevis.

Understanding how skeleton changes shape in ontogeny is fundamental to understanding how its shape diversifies in phylogeny. Amphibians pose a special case because their jaw and throat skeleton consists of cartilages that are dramatically reshaped midway through life to support new feeding and breathing styles. Although amphibian metamorphosis is commonly studied by immersing larvae in thyroid hormones (TH), how individual cartilages respond to TH is poorly understood. This study documents the effects of larval stage and TH type (T4 vs. T3), dose and deprivation on the size, shape and morphogenesis of the lower jaw and ceratohyal cartilages in the frog Xenopus laevis. It uses thyroid inhibitors to isolate the effects of each hormone at specific concentrations. It also deconstructs the TH responses into the effects on individual dimensions, and uses measures of percent change to eliminate the effects of body size and growth rate variation. As stage increases, T4 and T3 responses become increasingly similar to each other and to natural remodeling; the differences at low and intermediate stages result largely from abnormal responses to T3. Most notably, the beak-like lower jaw commonly observed at the lowest stage in other studies results largely from arrested growth of cartilage. TH responses are superimposed upon the growth typical for each stage so that cartilages can attain postmetamorphic shapes through dimensional changes that exceed those of natural metamorphosis. Using thyroid inhibitors alters the outcome of TH-induced remodeling, and T4 has almost the same capacity to induce metamorphic shape changes as T3. The results have implications for understanding how the starting shapes of larval elements affect morphogenesis, how chondrocytes behave to change cartilage shape, and how intracellular processing of TH might contribute to interspecific differences in shape change. Also, the data on animal mortality and which stages and doses most closely replicate natural remodeling have practical value for researchers who treat Xenopus tadpoles with TH.

Assessment of Adherence to Baseline Quality Measures for Cirrhosis and the Impact of Performance Feedback in a Regional VA Medical Center.

Baseline adherence to cirrhotic quality improvement measures was assessed and a system to improve adherence with provider performance feedback was developed, with impact of feedback measured over time. A 6-year retrospective database was created of cirrhotic patients seen between 2006 and 2012, and reviewed for hepatitis A and B serologies, hepatocellular carcinoma (HCC) screening, variceal screening, and vaccinations. Cumulative performance feedback was distributed to providers. In all, 265 charts were reviewed retrospectively. Charts were reviewed prospectively at 30 days, 60 days, 6 months, and 12 months. Variceal screening, alpha-fetoprotein, HCC imaging, Pneumovax, lifetime influenza vaccination, hepatitis B vaccination, and hepatitis A serology compliance improved from baseline until 6 months. Hepatitis A vaccination declined at 60 days, but improved from baseline at 6 months. Hepatitis B serology improved from baseline over 12 months. Results were compared graphically. Periodic "cumulative provider performance feedback" is a simple and effective method to improve and maintain adherence to quality measures for cirrhosis.

Immediate hypersensitivity to chlorhexidine.

Chlorhexidine is a widely used and effective antiseptic agent. Although skin contact is usually well tolerated, it may cause both immediate and delayed hypersensitivity reactions. We report a case of immediate hypersensitivity to chlorhexidine causing both skin and respiratory symptoms following occupational exposure to chlorhexidine in a health-care worker.

Debunking the Myth of Wool Allergy: Reviewing the Evidence for Immune and Non-immune Cutaneous Reactions.

Although wool is commonly believed to cause irritant (non-immune) and hypersensitivity (immune) cutaneous reactions, the evidence basis for this belief and its validity for modern garments have not been critically examined. Publications from the last 100 years, using MEDLINE and Google Scholar, were analysed for evidence that wool causes cutaneous reactions, both immune-mediated (atopic dermatitis exacerbation, contact urticaria, allergic contact dermatitis) and non-immune-mediated (irritant contact dermatitis, itch). Secondary aims of this paper were to examine evidence that lanolin and textile-processing additives (formaldehyde, chromium) cause cutaneous reactions in the context of modern wool-processing techniques. Current evidence does not suggest that wool-fibre is a cutaneous allergen. Furthermore, contact allergy from lanolin, chromium and formaldehyde is highly unlikely with modern wool garments. Cutaneous irritation from wool relates to high fibre diameters (≥ 30-32 µm). Superfine and ultrafine Merino wool do not activate sufficient c-fibres to cause itch, are well tolerated and may benefit eczema management.

A Cooking Intervention to Increase Vegetable Consumption by Parents With Children Enrolled in an Early Head Start Home Visiting Program: A Pilot Study in Portland, Oregon, 2013-2014.

INTRODUCTION: Cooking interventions may improve diet quality. Most cooking interventions are delivered in group settings. Home visiting programs may be an appropriate mechanism for delivering such interventions to low-income families with young children. We conducted a pilot study to test the feasibility of using a cooking intervention delivered by home visitors to improve attitudes and behaviors related to vegetable consumption by low-income parents with children enrolled in a home visiting program. METHODS: We invited 121 parents with children enrolled in an Early Head Start Home Visiting program in Portland, Oregon, to participate. During 2013-2014, each month for 8 months, home visitors (n = 14) implemented 1 cooking activity plus 1 complementary activity focused on 12 vegetables. We collected pre- and post-intervention data on participants' cooking confidence and whether they tried and liked the selected vegetables. We also measured fidelity to protocol and home visitors' perception of intervention usability. RESULTS: Of 104 participants, 58 provided pre- and post-intervention data. We observed a significant increase in confidence in baking, roasting or grilling vegetables; cooking 6 of 10 vegetables; and trying 7 of 12 vegetables. Nearly all respondents participated in the monthly cooking activity (96%) and complementary activity (94%). Twelve of 14 home visitors reported that the intervention was acceptable, feasible, and easy to understand, and needed systems supports to implement. CONCLUSION: Cooking interventions may be a feasible approach to improving attitudes and behaviors related to vegetable consumption by low-income families with young children. Additional research is needed to assess the impact of such interventions on vegetable consumption.

Occupational skin disease among Australian healthcare workers: a retrospective analysis from an occupational dermatology clinic, 1993-2014.

BACKGROUND: Healthcare workers (HCWs) are at risk of developing occupational skin disease (OSD). OBJECTIVES: To ascertain the causes of OSD in Australian HCWs in a tertiary referral clinic. METHODS: A retrospective review was performed of patients assessed at the Occupational Dermatology Clinic in Melbourne from 1993 to 2014. RESULTS: Of 685 HCWs assessed in the clinic over a period of 22 years, 555 (81.0%) were diagnosed with OSD. The most common diagnosis was irritant contact dermatitis (ICD) (79.1%), followed by allergic contact dermatitis (ACD) (49.7%). Natural rubber latex allergy was also relatively frequent (13.0%). The major substances causing ACD were rubber glove chemicals (thiuram mix and tetraethylthiuram disulfide), preservatives (formaldehyde, formaldehyde releasers, and isothiazolinones), excipients in hand cleansers, which are hard-to-avoid weak allergens, and antiseptics. ACD caused by commercial hand cleansers occurred more frequently than ACD caused by alcohol-based hand rubs (ABHRs). Occupational ICD was mostly caused by water/wet work and hand cleansers, and environmental irritants such as heat and sweating. CONCLUSIONS: Understanding the causes of OSD in HCWs is important in order to develop strategies for prevention. We suggest that skin care advice should be incorporated into hand hygiene education. The use of ABHRs should be encouraged, weak allergens in skin cleansers should be substituted, and accelerator-free gloves should be recommended for HCWs with OSD.

Airborne exposure to methylisothiazolinone in paint causing allergic contact dermatitis: An Australian perspective.

An alarming increase in contact allergy to methylisothiazolinone (MI) has been noted worldwide. Airborne exposure to MI in paint is an acknowledged occupational hazard. We present the first Australian report of airborne allergic contact dermatitis (ACD) following exposure to wall paint containing MI.
