Homicides of American Indians/Alaska Natives in urban versus rural areas: United States National Violent Death Reporting System, 2003-2020.

BACKGROUND: Missing and Murdered Indigenous People is a historic and contemporary issue that has gained national attention. In 2021, homicide was the eighth leading cause of death among American Indian/Alaska Native (AIAN) persons aged between 1 and 54 years old, and homicide is the sixth leading cause of death among all AIAN males aged 1-54 years old. AIM: These data will build knowledge around AIAN homicides and to identify circumstances that can aid in comprehensive Missing and Murdered Indigenous People prevention efforts. METHODS: AIAN homicide data came from Centers for Disease Control and Prevention's National Violent Death Reporting System, a state/jurisdiction-based surveillance system that collects detailed information about characteristics and circumstances of violent deaths. We examined data from 2003 to 2020 (all available years) from participating states/jurisdictions. We also assessed sociodemographic characteristics of victims and suspects, incident characteristics and differences across dichotomised urban/rural status. The study was conducted in 2022. RESULTS: The National Violent Death Reporting System provided data on 2959 AIAN homicides from 2003 to 2020 (54.2% urban and 45.8% rural). Significant differences based on the two locations included type of weapon used, the location of the injury, race of the primary suspect, the victim's relationship to the suspect and select circumstances precipitating the homicide including crimes precipitating the homicide and homicides stemming from intimate partner violence. OUTCOMES: These findings provide crucial information to strengthen public health efforts for prevention.

Prevalence estimates and factors associated with violence among older adults: National Intimate Partner and Sexual Violence (NISVS) Survey, 2016/2017.

Abuse of older adults is a public health problem. The National Intimate Partner and Sexual Violence Survey (NISVS) is a nationally-representative, telephone survey for non-institutionalized adults in the United States. To determine the prevalence and factors of intimate partner psychological aggression and physical violence and sexual violence by any perpetrator against older adults, we analyzed NISVS 2016/2017 data (n = 10,171, aged ≥ 60 years). Past 12-month prevalence of psychological aggression, physical violence, and sexual violence was 2.1%, 0.8%, and 1.7%, respectively. Odds of psychological aggression were significantly higher among those with hearing or vision impairment, and lower among those aged ≥70 years. Odds of physical violence were significantly higher for males and for those with hearing or vision impairment. Odds of sexual violence were significantly higher for unpartnered individuals and those with cognitive impairment; and lower for those aged ≥ 70 years. Epidemiologic studies of violence against older adults can inform population-specific prevention strategies.

Permafrost thaw induces short-term increase in vegetation productivity in northwestern Canada.

Over the past several decades, various trends in vegetation productivity, from increases to decreases, have been observed throughout Arctic-Boreal ecosystems. While some of this variation can be explained by recent climate warming and increased disturbance, very little is known about the impacts of permafrost thaw on productivity across diverse vegetation communities. Active layer thickness data from 135 permafrost monitoring sites along a 10° latitudinal transect of the Northwest Territories, Canada, paired with a Landsat time series of normalized difference vegetation index from 1984 to 2019, were used to quantify the impacts of changing permafrost conditions on vegetation productivity. We found that active layer thickness contributed to the observed variation in vegetation productivity in recent decades in the northwestern Arctic-Boreal, with the highest rates of greening occurring at sites where the near-surface permafrost recently had thawed. However, the greening associated with permafrost thaw was not sustained after prolonged periods of thaw and appeared to diminish after the thaw front extended outside the plants' rooting zone. Highest rates of greening were found at the mid-transect sites, between 62.4° N and 65.2° N, suggesting that more southernly sites may have already surpassed the period of beneficial permafrost thaw, while more northern sites may have yet to reach a level of thaw that supports enhanced vegetation productivity. These results indicate that the response of vegetation productivity to permafrost thaw is highly dependent on the extent of active layer thickening and that increases in productivity may not continue in the coming decades.

Equity with equality? Contextualising everyone can widen participation in medical school admissions.

Widening participation outcomes in admissions to UK medical schools have not changed 2007-2018, partly due to inequity in selection. This study models the effects of changing selection, using a novel method of contextualising applicants, on widening participation. We studied 1084 English school leaver applicants to a single medical school over two years, using data from their public exams taken 2 years pre-application (GCSE) and recent admissions test (UCAT). Widening participation was defined by postcode.We modelled two shortlists for a pre-determined number of 500; one ranked on UCAT total score, and the other on a metric that contextualised applicants' GCSE grades against their schools' average GCSE performance. There was a significant difference in the postcode-defined widening participation characteristics of the two shortlists; 46% by contextualisation and 32.2% by UCAT (Chisquare p < 0.00001). As widening participation covers 42% of postcodes, the "contextualise everyone" method achieves equity.Conventionally, contextual admissions identify individuals belonging to under-represented groups and gives them preferential treatment. Changing the rules for everyone, by using a relative attainment instead of simple absolute attainment metric, benefits from treating applicants equally; and could promote equity through widening participation.

Violent Victimization During Childhood in the United States: Associations With Revictimization and Health.

Childhood violence victimization is a serious adverse childhood experience with lasting health impacts. This study examined the prevalence and characteristics of five forms of childhood violence victimization and their association with revictimization and negative health conditions among adults. Data are from the 2010-2012 National Intimate Partner and Sexual Violence Survey. Age at first victimization and perpetrator sex were assessed; adjusted odds ratios assessed associations with revictimization and health. Ages 14-17 were the most common age at first victimization for most violence types; almost half of male (46.7%) and a quarter of female (27.0%) rape victims reported first victimization before age 10. Most victimization was associated with revictimization and negative health, controlling for adult victimization. Primary prevention of childhood violence may reduce later health risks.

Effects of Acute Tryptophan Depletion on Human Taste Perception.

Taste perception has been reported to vary with changes in affective state. Distortions of taste perception, including blunted recognition thresholds, intensity, and hedonic ratings have been identified in those suffering from depressive disorders. Serotonin is a key neurotransmitter implicated in the etiology of anxiety and depression; systemic and peripheral manipulations of serotonin signaling have previously been shown to modulate taste detection. However, the specific effects of central serotonin function on taste processing have not been widely investigated. Here, in a double-blind placebo-controlled study, acute tryptophan depletion was used to investigate the effect of reduced central serotonin function on taste perception. Twenty-five female participants aged 18-28 attended the laboratory on two occasions at least 1 week apart. On one visit, they received a tryptophan depleting drink and on the other, a control drink was administered. Approximately, 6 h after drink consumption, they completed a taste perception task which measured detection thresholds and supra-threshold perceptions of the intensity and pleasantness of four basic tastes (sweet, sour, bitter, and salt). While acutely reducing central levels of serotonin had no effect on the detection thresholds of sweet, bitter, or sour tastes, it significantly enhanced detection of salt. For supra-threshold stimuli, acutely reduced serotonin levels significantly enhanced the perceived intensity of both bitter and sour tastes and blunted pleasantness ratings of bitter quinine. These findings show manipulation of central serotonin levels can modulate taste perception and are consistent with previous reports that depletion of central serotonin levels enhances neural and behavioral responsiveness to aversive signals.

Violence prevention emergency tool (VPET) screening of youth in the pediatric ED.

Background Violence is an increasingly common and significant problem for youth worldwide. Youth who rely on treatment at urban EDs are more likely to die as the result of violence than any other disease/condition for which they seek care. The first step in helping youth that are at risk, is identifying them. We developed a 7-item screening tool called VPET. The purpose of this study is to validate the VPET screening tool in identifying high-risk youth. Methods and findings We prospectively enrolled a convenience sample of children during the index ED visit who were called 3 months and 6 months after this visit. 269 youth (33%) completed 3-month follow up (44.2% male); 240 youth (29.4%) completed 6-month follow up (45% male); 84.0% reported some level of violence exposure after 3-months and 84.2% (n = 240) reported some level of violence exposure after 6-months. Predictive validity was assessed by Spearman's correlation between VPET score and follow-up score at 3-months and 6-months post-enrollment; logistic regression to calculate odds ratios between positive VPET item responses and positive follow-up score; ROC curve analysis. VPET score had internal consistency, as tested by Cronbach's alpha (α = 0.642). Children who were male, non-white, and had been hurt at home or school reported the highest VPET scores. Conclusion VPET has sufficiently strong psychometric function and performs well as a screening tool to predict future violence exposure for youth ages 8-17. Five questions on the VPET screening tool are independently predictive of violence reported at 6 months and four questions at 3 months.

Predictors for Acute Appendicitis in Children.

BACKGROUND: Acute appendicitis in children is the most common condition requiring urgent evaluation and surgery in the emergency department. At times, despite the appendix being seen on ultrasound (US), there can be discrepancy as to whether a patient has clinical appendicitis. Secondary findings suggestive of appendicitis can be helpful in identifying and evaluating these children. OBJECTIVE: The aim of this study was to determine if specific US findings and/or laboratory results are predictive of appendicitis in children with a visualized appendix on US. METHODS: A prospective study was conducted on children (birth to 18 years) presenting to the pediatric emergency department with suspected appendicitis who underwent right-lower-quadrant US. Ultrasound findings analyzed appendix diameter, compressibility, increased vascularity, presence of appendicolith, inflammatory changes, right-lower-quadrant fluid near the appendix, lower abdominal fluid, tenderness during US, and lymph nodes. Diagnosis was confirmed via surgical pathology. RESULTS: There were 1252 patients who enrolled, 60.8 (762) had their appendix visualized, and 39.1 (490) did not. In children where the appendix was seen, 35.2% (268) were diagnosed with appendicitis. Among patients with a visualized appendix, the likelihood of appendicitis was significantly greater if the appendix diameter was 7 mm or greater (odds ratio [OR], 12.4; 95% confidence interval [CI], 4.7-32.7), an appendicolith was present (OR, 3.9; 95% CI, 1.5-10.3), inflammatory changes were seen (OR, 10.2; 95% CI, 3.9-26.1), or the white blood cell (WBC) count was 10,000/µL (OR, 4.8; 95% CI, 2.4-9.7). A duration of abdominal pain of 3 days or more was significantly less likely to be associated with appendicitis (OR, 0.3; 95% CI, 0.08-0.99). The absence of inflammatory changes, WBC count of less than 10,000/µL, and appendix diameter of 7 mm or less had a negative predictive value of 100%. CONCLUSIONS: When the appendix is seen on US but diagnosis of appendicitis is questioned, the absence of inflammatory changes, WBC count of less than 10,000/µL, and appendix diameter of 7 mm or less should decrease suspicion for appendicitis.

Social networks and people with intellectual disabilities: A systematic review.

BACKGROUND: Despite the importance of social networks for health and well-being, relatively little is known about the ways in which adults with intellectual disabilities in the U.K. experience their social networks. METHOD: A systematic review was completed to identify research focused on the social networks of adults with intellectual disabilities. Studies published from 1990 to 2019 were identified. Studies were thematically analysed. RESULTS: Quantitative, qualitative and mixed methods studies were analysed to identify key factors influencing social networks. Experiences of people with intellectual disabilities identified themes of identity, powerlessness, inclusion, family and support. These themes are discussed with reference to theories of stigma and normalisation. CONCLUSIONS: Stigma and normalisation can be used to better understand the needs, desires and dreams of people with intellectual disabilities for ordinary relationships, from which they are regularly excluded. Implications for policy and practice are discussed in relation to building and repairing often spoiled identities.

Patient-reported outcomes in sickle cell disease and association with clinical and psychosocial factors: Report from the sickle cell disease implementation consortium.

Understanding patient experiences, quality of life, and treatment needs in individuals with sickle cell disease (SCD) is essential in promoting health and well-being. We used measures from the Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me), Patient Reported Outcomes Measurement Information System (PROMIS), and Quality of Life in Neurological Disorders (NeuroQol) to evaluate pain impact, sleep impact, social functioning, depressive symptoms, tiredness, and cognitive function (collectively, patient reported outcomes [PROs]) and to identify associated demographic and clinical characteristics. Participants (n = 2201) between 18 and 45 years were recruited through the eight Sickle Cell Disease Implementation Consortium (SCDIC) sites. In multivariate models, PROs were significantly associated with one another. Pain impact was associated with age, education, employment, time since last pain attack, hydroxyurea use, opioid use, sleep impact, social functioning, and cognitive function (F = 88.74, P < .0001). Sleep impact was associated with household income, opioid use, pain impact, social functioning, depressive symptoms, and tiredness (F = 101.40, P < .0001). Social functioning was associated with employment, pain attacks in the past year, autoimmune/inflammatory comorbidities, pain impact, sleep impact, depressive symptoms, tiredness, and cognitive function (F = 121.73, P < .0001). Depressive symptoms were associated with sex, sleep impact, social functioning, tiredness, and cognitive function (F = 239.51, P < .0001). Tiredness was associated with sex, education, sleep impact, social functioning, depressive symptoms, and cognitive function (F = 129.13, P < .0001). These findings reflect the baseline PRO assessments among SCDIC registry participants. Further research is needed to better understand these outcomes and new targets for interventions to improve quality of life and function in people with SCD.

Point-of-Care Influenza Testing in the Pediatric Emergency Department.

OBJECTIVES: To see what the impact of introducing a rapid polymerase chain reaction-based influenza test has on length of stay (LOS) in emergency department, use of imaging, serum or urine testing, antibiotic use, and antiviral use. METHODS: Audit of electronic medical health records was performed for all emergency department visits from 2014 to 2018 between November and March, which was defined as peak flu season. Patients were included if they were between 3 months and 18 years of age, presented during peak flu season, and were tested for influenza. The pre-point of care (POC) period was defined as November through March of 2014 to 2017 which was compared with the post-POC group which was defined as November through March of 2017 to 2018. RESULTS: Patients tested for influenza in the pre-POC period were more likely to have complete blood count testing (44.7% vs 25.6% P < 0.01), more likely to have blood cultures performed (30% vs 16.3%, P < 0.01), more likely to have urine testing performed (21.5% vs 12.2%, P < 0.01), and more likely to have a chest radiograph completed (47.5% vs 34.4%, P < 0.01). There was no significant difference in rates of antibiotics used. There was increased rates of oseltamivir used in the post-POC period (21.2% vs 13.3%, P < 0.05. The median LOS decreased from 239 minutes in the pre-POC period to 232 minutes in the post-POC period (P < 0.05). CONCLUSIONS: With the introduction of a polymerase chain reaction-based point-of-care influenza test, there were overall decreased rates of invasive blood work, urine studies, and imaging, and median LOS. There was also increased antiviral administration.

Fast and Sensitive: Automated Point-of-Care Urine Dips.

OBJECTIVE: Point-of-care (POC) urine dipstick is a highly used test in the pediatric emergency department (PED) owing to its fast turn-around time and inexpensive cost. Past studies have shown hand-held urine dipsticks and automated urinalysis in children younger than 48 months to be sensitive predictors for urinary tract infection (UTI). It is hypothesized that POC dip testing is as accurate as laboratory urinalysis in the diagnosis of UTI. METHODS: A retrospective chart review was conducted on patients (aged birth through 18 years) presenting to a PED between January 2015 and December 2015. Eligible subjects included those that had a POC dip, laboratory urinalysis (lab UA), and urine culture performed during their PED visit. Subjects were selected, using a random number generator; 334 charts were selected. A positive POC dip was defined as having a positive leukocyte esterase or the presence of nitrites. A positive lab UA was defined as having a positive leukocyte esterase, nitrites, or greater than 10 white blood cells per high-power field. Urine culture was used as the criterion standard for comparison. RESULTS: A total of 334 subjects' charts were reviewed. Sensitivity and specificity of the POC dip were 91.4% (95% confidence interval [CI], 76.9%-98.2%) and 63.9% (95% CI, 57.2%-69.3%); lab UA, 91.4% (95% CI, 76.9%-98.2%) and 63.9% (95% CI, 58.2%-69.3%); and lab dip, 88.6% (95% CI, 73.3%-96.8%) and 65.6% (95% CI, 59.9%-70.9%). CONCLUSIONS: Point-of-care dips are as sensitive in detecting UTI as the lab UA. A prospective study could allow for further demographic evaluation of POC dip diagnosed UTI.

A Process for Identifying Indicators With Public Data: An Example From Sexual Violence Prevention.

Despite advances in the sexual violence (SV) prevention field, practitioners still face challenges with identifying indicators to measure the impact of their prevention strategies. Public data, such as existing administrative and surveillance system data, may be a good option for organizations to examine trends in indicators for the purpose of program evaluation. In this article, we describe a framework and a process for identifying indicators with public data. Specifically, we present the SV Indicator Framework and a five-step indicator review process, which we used to identify indicators for a national SV prevention program. We present the findings of the indicator review and explain how the process could be used by evaluators and program planners within other developing topic areas. Tracking indicators with public data, in conjunction with other evaluation methods, may be a viable option for state-level program evaluations. We discuss limitations and implications for practice and research.

Diagnostic accuracy of laboratory and ultrasound findings in patients with a non-visualized appendix.

Ultrasound (US) and laboratory testing are initial diagnostic tests for acute appendicitis. A diagnostic dilemma develops when the appendix is not visualized on US. Objective: To determine if specific US findings and/or laboratory results predict acute appendicitis when the appendix is not visualized. Methods: A prospective study was conducted on children (birth-18 yrs) presenting to the pediatric emergency department with suspected acute appendicitis who underwent right lower quadrant US. Children with previous appendectomy, US at another facility, or eloped were excluded. US findings analyzed: inflammatory changes, right lower quadrant and lower abdominal fluid, tenderness during US exam and lymph nodes. Diagnoses were confirmed via surgical pathology. Results 1252 subjects were enrolled, 60.8% (762) had appendix visualized and 39.1% (490) did not. In children where the appendix was not seen, 6.7% [33] were diagnosed with appendicitis. Among patients with a non-visualized appendix, the likelihood of appendicitis was significantly greater if: inflammatory changes in the RLQ (OR 18.0, 95% CI 4.5-72.1), CRP >0.5 mg/dL (OR 2.64, 95% CI 1.0-6.8), or WBC > 10 (OR 4.36, 95% CI 1.66-11.58). Duration of abdominal pain >3 days was significantly less likely associated with appendicitis in this model (OR 0.34, 95% CI 0.003-0.395). Combined, the absence inflammatory changes, CRP < 0.5 mg/dL, WBC < 10, and pain, ≤3 days had a NPV of 94.0%. Conclusion When the appendix is not visualized on US, predictors for appendicitis include the presence of inflammatory changes in the RLQ, an elevated WBC/CRP and abdominal pain <3 days.

Pediatric Adapted Liking Survey: A Novel, Feasible and Reliable Dietary Screening in Clinical Practice.

PURPOSE: Rapid yet useful methods are needed to screen for dietary behaviors in clinical settings. We tested the feasibility and reliability of a pediatric adapted liking survey (PALS) to screen for dietary behaviors and suggest tailored caries and obesity prevention messages. METHODS: In an observational study, children admitted to a pediatric emergency department (PED) for nonurgent care were approached to complete the PALS (33 foods, 4 nonfoods including brushing teeth). Measured height/weight were used for body mass index (BMI) percentile determination. Feasibility was assessed by response rate and PALS completion time. Reliability was assessed by internal consistency of food groups and test-retest reliability for PED-home reported PALS. RESULTS: PALS was completed by 144 children (96% of approached) - 54% male (average age = 11 ± 3 years) with diversity in family income (43% publicly insured), race/ethnicity (15% African American, 33% Hispanic, 44% Caucasian) and adiposity (3% underweight, 50% normal, 31% overweight, 17% obese, 8% extremely obese). The average completion time was 3: 52 min, and conceptual food groups had reasonable internal reliability. From 57% (n = 82) with PED-home completion, PALS had a good/excellent test-retest reliability. Relative preferences for sweets versus brushing teeth identified unique groups of children for tailored prevention messages (high sweet/brushing preference, sweets > brushing, brushing > sweets). Females with higher adiposity reported significantly greater preference for sweet/high-fat foods, independently of demographic variables; the relationship was nonsignificant in males and with the other food groups. CONCLUSION: The PALS appears to be a fast, feasible and reliable dietary screener in a clinical setting to assist in forming tailored diet-related messages for dental caries and obesity prevention.

Unwelcoming: The Church Experiences of HIV-Infected Adolescents and Emerging Adults.

Acceptance among family, friends, and within the community is a critical developmental milestone during adolescence. Having a diagnosis of HIV may hinder or impede one's ability to develop socially. The purpose of our original study was to describe the role spirituality may play in HIV-infected adolescents and emerging adults. We interviewed 21 Christian-identified males using constructivist grounded theory methodology. The theory of the church not embracing HIV-infected youth was generated. The theme "unwelcoming" describes young people's attempts to connect with the church. Embracing adolescents and emerging adults in church may offer support and enhance their ability to cope with HIV.

Three-generation family with novel contiguous gene deletion on chromosome 2p22 associated with thoracic aortic aneurysm syndrome.

Latent transforming growth factor binding proteins (LTBP) are a family of extracellular matrix glycoproteins that play an important role in the regulation of transforming growth factor beta (TGF-ß) activation. Dysregulation of the TGF-ß pathway has been implicated in the pathogenesis of inherited disorders predisposing to thoracic aortic aneurysms syndromes (TAAS) including Marfan syndrome (MFS; FBN1) and Loeys-Dietz syndrome (LDS; TGFBR1, TGFBR2, TGFB2, TGFB3, SMAD2, SMAD3). While these syndromes have distinct clinical criteria, they share clinical features including aortic root dilation and musculoskeletal findings. LTBP1 is a component of the TGF-ß pathway that binds to fibrillin-1 in the extracellular matrix rendering TGF-ß inactive. We describe a three-generation family case series with a heterozygous ∼5.1 Mb novel contiguous gene deletion of chromosome 2p22.3-p22.2 involving 11 genes, including LTBP1. The deletion has been identified in the proband, father and grandfather, who all have a phenotype consistent with a TAAS. Findings include thoracic aortic dilation, ptosis, malar hypoplasia, high arched palate, retrognathia, pes planus, hindfoot deformity, obstructive sleep apnea, and low truncal tone during childhood with joint laxity that progressed to reduced joint mobility over time. While the three affected individuals did not meet criteria for either MFS or LDS, they shared features of both. Although the deletion includes 11 genes, given the relationship between LTBP1, TGF-ß, and fibrillin-1, LTBP1 stands out as one of the possible candidate genes for the clinical syndrome observed in this family. More studies are necessary to evaluate the potential role of LTBP1 in the pathophysiology of TAAS.

Asthmonia: A clinical definition of a commonly used colloquial term.

OBJECTIVE: To describe the clinical characteristics of pediatric asthmonia, a syndrome in which children have both an acute asthma exacerbation and a concomitant diagnosis of community acquired pneumonia. METHODS: A retrospective chart review was conducted on children admitted to Connecticut Children's Medical Center in the pediatric emergency department from January 1, 2012 to December 31, 2012. Children with asthma and pneumonia were identified using ICD-9 codes 493 (asthma) or 482 (pneumonia). In this study, we defined asthmonia, a third group, based on the following criteria: (1) history of asthma based on documentation in the past medical history section of the chart, (2) documented wheezing on presentation, (3) administration of bronchodilator(s), and (4) new focal infiltrate on chest radiograph during ED visit. The three nonoverlapping groups (asthma, pneumonia, and asthmonia) were described. RESULTS: Three hundred and sixty-eight children were identified for our study population. In the study population, 66.0% (N = 243) had asthma, 20.4% (N = 75) pneumonia, and 13.6% (N = 50) met our definition of asthmonia. We found that 84.0% (N = 42) of children who met asthmonia criteria in our study were treated with antibiotic therapies. Also, 28.0% (N = 14) of children who met asthmonia criteria had documented fever during admission or by parent report. CONCLUSIONS: This study defined clinical features of the coexistence of pneumonia in children with asthma. Overall, these children frequently presented with fever and were treated with antibiotics. More studies are needed to better elucidate this clinical entity and its ramifications.

Revisiting the Appendiceal Diameter via Ultrasound for the Diagnosis of Acute Appendicitis.

OBJECTIVES: This study aims to investigate the optimal outer appendiceal diameter via ultrasound for the diagnosis of acute appendicitis. METHODS: A retrospective chart review was conducted on patients (ages, 2-18 years) presenting to an urban pediatric emergency department between January 1, 2009 and December 31, 2010 with suspected acute appendicitis. Children were considered as having "suspected acute appendicitis" if they (1) presented with acute abdominal pain and had either a surgical consult or an abdominal ultrasound, or (2) presented or transferred with the stated suspicion of acute appendicitis. Pathology reports were used to confirm the diagnosis of appendicitis. The appendiceal diameters were determined by board-certified pediatric radiologists. RESULTS: A total of 320 patient charts were reviewed (females, 57%; mean age, 10.9; SD, 3.9). Seventy-two percent (N = 230) of the patients screened positive for acute appendicitis via ultrasound, 69% (N = 222) had confirmed acute appendicitis, 75% (N = 239) of the ultrasound reports included an outer appendiceal diameter. Overall, ultrasound was found to be highly sensitive (91%) and moderately specific (74%). With an outer appendiceal diameter of 6 mm as a cutoff, ultrasound had an excellent sensitivity (100%) but poor specificity (43%). With an outer diameter of 7 mm as a cutoff, sensitivity decreased to 94% but specificity increased to 71%. With increasing cutoff size, the sensitivity decreased and specificity increased. CONCLUSIONS: Our data suggest that the optimal outer appendiceal diameter for the diagnosis of acute appendicitis should be 7 mm instead of the currently used 6 mm.

Safe Patient Handling and Mobility: Development and Implementation of a Large-Scale Education Program.

This article addresses the development, implementation, and evaluation of an education program for safe patient handling and mobility at a large academic medical center. The ultimate goal of the program was to increase safety during patient mobility/transfer and reduce nursing staff injury from lifting/pulling. This comprehensive program was designed on the basis of the principles of prework, application, and support at the point of care. A combination of online learning, demonstration, skill evaluation, and coaching at the point of care was used to achieve the goal. Specific roles and responsibilities were developed to facilitate implementation. It took 17 master trainers, 88 certified trainers, 176 unit-based trainers, and 98 coaches to put 3706 nurses and nursing assistants through the program. Evaluations indicated both an increase in knowledge about safe patient handling and an increased ability to safely mobilize patients. The challenge now is sustainability of safe patient-handling practices and the growth and development of trainers and coaches.
