Quantitative physical performance tests can effectively detect Degenerative Cervical Myelopathy: A systematic review and meta-analysis.

PURPOSE: This review aimed to identify effective physical performance tests (PPT) as clinical outcome indicators for detecting and monitoring degenerative cervical myelopathy (DCM). METHODS: A comprehensive literature search was performed on seven electronic databases on the effectiveness in detection and monitoring of DCM by PPT. All included studies were reviewed and undergone quality assessments on the risk-of-bias by Newcastle-Ottawa Scale and were pooled by random-effect analysis with level of significance at 0.05. Homogeneity among studies was assessed by I2-statistics and effect of PPT was confirmed by Cohen's d effect size and confidence intervals. RESULTS: Totally, 3111 articles were retrieved, and 19 studies were included for review and meta-analysis. There were 13 studies investigating PPT regarding the upper limbs and 12 studies regarding the lower limbs. Performance in 10-second-Grip-and-Release Test (G&R) and 9-Hole-Peg Test (9HPT) was studied in 10 and 3 articles, respectively, while 10-second-Stepping Test (SST), 30-meter-Walking Test (30MWT) and Foot-Tapping Test (FTT) for lower limbs were studied in 5, 4, and 3 articles correspondingly. Only 1 study utilized the Triangle-Stepping Test. High-quality study with fair risk-of-bias was revealed from Newcastle-Ottawa scale. Large effect size facilitated detection and monitoring in DCM was unveiling for G&R, 9HPT, SST, and 30MWT. FTT, while also effective, was hindered by a high-degree heterogeneity in the meta-analysis. CONCLUSION: Effective PPT including G&R, 9HPT, SST, 30MWT, and FTT was identified for disease detection and monitoring in DCM.

Relation of Mild Traumatic Brain Injury history to abnormalities on a preliminary Neuroendocrine screen; A multicenter LIMBIC-CENC analysis.

PRIMARY OBJECTIVES: Determine if an abnormal preliminary neuroendocrine disorder (NED) blood test screen is associated with mild TBI (mTBI) history or post-concussiveclinical features. RESEARCH DESIGN: Observational. METHODS: Among 1,520 participants with military combatexposure, we measured randomly timed serum levels of insulin-likegrowth factor-1, thyroid stimulating hormone (TSH), and total testosterone as a preliminary NED screen. Using multivariable models, we analyzed relation of screen results in mTBI group membership and post-concussiveclinical features (fatigue, depression, cognitive symptoms, executive function, processing speed). RESULTS: None of the mTBI positive groups, including repetitive (≥3 mTBI) and blast-related,differed from the non-TBIcontrols on rates of abnormal lab screen or rates of growth hormone deficiency (GHD), hypothyroidism or male hypogonadism in treatment records. Lab screen findings were also not associated with any clinical feature. CONCLUSIONS: This study shows no evidence that remote mTBI(s) or implicated post-concussiveclinical features are linked to GHD, hypothyroidism or male hypogonadism. Large case-controlstudies incorporating more definitive neuroendocrine disorder NED testing (TSH plus thyroxine, early morning testosterone, LH, FSH, prolactin and GH provocative testing) are needed to determine whether mTBI(s) alone elevate one's risk for chronic NED and how best to select patients for comprehensive testing.

COVID-19 impact on screening test volume through the National Breast and Cervical Cancer early detection program, January-June 2020, in the United States.

Women from racial and ethnic minority groups face a disproportionate burden of cervical and breast cancers in the United States. The Coronavirus Disease 2019 (COVID-19) pandemic might exacerbate these disparities as supply and demand for screening services are reduced. The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides cancer screening services to women with low income and inadequate health insurance. We examined COVID-19's impact on NBCCEDP screening services during January-June 2020. We found the total number of NBCCEDP-funded breast and cervical cancer screening tests declined by 87% and 84%, respectively, during April 2020 compared with the previous 5-year averages for that month. The extent of declines varied by geography, race/ethnicity, and rurality. In April 2020, screening test volume declined most severely in Health and Human Services Region 2 - New York (96% for breast, 95% for cervical cancer screening) compared to the previous 5-year averages. The greatest declines were among American Indian/Alaskan Native women for breast cancer screening (98%) and Asian Pacific Islander women for cervical cancer screening (92%). Test volume began to recover in May and, by June 2020, NBCCEDP breast and cervical cancer screening test volume was 39% and 40% below the 5-year average for that month, respectively. However, breast cancer screening remained over 50% below the 5-year average among women in rural areas. NBCCEDP programs reported assisting health care providers resume screening.

"Nowhere else to be found": Drawing on peer support experiences among transgender and gender-diverse people to substantiate community-driven gender-affirming care.

Increasingly, applied social scientists and clinicians recognize the value of engaging transgender and gender-diverse (TGD) people, particularly TGD individuals with lived experience as care recipients (peers), to inform the provision of gender-affirming care. Despite this trend, few researchers have systematically examined how this group can contribute to and enhance the development and delivery of interventions intended to affirm gender diversity. In this article, we address limitations in the literature by drawing on a secondary analysis of qualitative data - originally collected to examine the peer support experiences of TGD individuals - to explore the potential that TGD peers hold for elevating gender-affirming care. The study was informed methodologically by an abductive approach to grounded theory, and conceptually by critical resilience and intersectional scholarship. Data collection involved virtual, semi-structured interviews with 35 TGD individuals in two Canadian cities who indicated having experiences of seeking, receiving, and/or providing peer support. Data analysis comprised an iterative, abductive process of cross-referencing participant accounts with relevant scholarship to arrive at an account of how TGD peers may contribute to the growth of gender-affirming care. Our findings suggest, broadly, that TGD peers may enhance gender-affirming care by: (1) validating a growing diversity of embodiments and experiences in healthcare decision-making, (2) nurturing and diversifying relevant networks of safety, community support, and advocacy outside formal systems of care, and (3) strengthening possibilities for resisting and transforming existing healthcare systems. After outlining these findings, we briefly consider the implications of our analysis and leverage our inferences to substantiate the notion of community-driven gender-affirming care, meaning care that is intentional in its incorporation of relevant community stakeholders to shape governance and service provision. We conclude with reflections on the promise of community-driven care at a time of heightened volatility across systems serving TGD populations.

Proprioception-related gene mutations in relation to the aetiopathogenesis of idiopathic scoliosis: A scoping review.

Since idiopathic scoliosis is a multifactorial disorder, the proprioceptive defect is considered one of its etiological factors. Genetic studies have separately revealed this relationship, yet it remains indeterminate which specific genes that related to proprioception contributed to the initiation, progression, pathology, and treatment outcomes of the curvature. A systematic search was conducted on four online databases, including PubMed, Web of Science, Embase, and Academic search complete. Studies were included if they involved human or animal subjects with idiopathic scoliosis and evaluated with proprioceptive genes. The search period was the inception of the database to February 21, 2023. Four genes (i.e., Ladybird homeobox 1 [LBX1], Piezo type mechanosensitive ion channel component 2 [PIEZO2], Runx family transcription factor 3 [RUNX3], and neurotrophin 3 [NTF3]) investigated in 19 studies were included. LBX1 has confirmed the correlation with the development of idiopathic scoliosis in 10 ethnicities, whereas PIEZO2 has shown a connection with clinical proprioceptive tests in subjects with idiopathic scoliosis. However, curve severity was less likely to be related to the proprioceptive genes. The potential pathology took place at the proprioceptive neurons. Evidence of proprioception-related gene mutations in association with idiopathic scoliosis was established. Nevertheless, the causation between the initiation, progression, and treatment outcomes with proprioceptive defect requires further investigation.

Differentiating multi-MeV, multi-ion spectra with CR-39 solid-state nuclear track detectors.

The development of high intensity petawatt lasers has created new possibilities for ion acceleration and nuclear fusion using solid targets. In such laser-matter interaction, multiple ion species are accelerated with broad spectra up to hundreds of MeV. To measure ion yields and for species identification, CR-39 solid-state nuclear track detectors are frequently used. However, these detectors are limited in their applicability for multi-ion spectra differentiation as standard image recognition algorithms can lead to a misinterpretation of data, there is no unique relation between track diameter and particle energy, and there are overlapping pit diameter relationships for multiple particle species. In this report, we address these issues by first developing an algorithm to overcome user bias during image processing. Second, we use calibration of the detector response for protons, carbon and helium ions (alpha particles) from 0.1 to above 10 MeV and measurements of statistical energy loss fluctuations in a forward-fitting procedure utilizing multiple, differently filtered CR-39, altogether enabling high-sensitivity, multi-species particle spectroscopy. To validate this capability, we show that inferred CR-39 spectra match Thomson parabola ion spectrometer data from the same experiment. Filtered CR-39 spectrometers were used to detect, within a background of ~ 2 × 1011 sr-1 J-1 protons and carbons, (1.3 ± 0.7) × 108 sr-1 J-1 alpha particles from laser-driven proton-boron fusion reactions.

Is Scoliosis Associated with Dance Injury in Young Recreational Dancers? A Large-Scale Cross-Sectional Epidemiological Study.

Some studies suggested that adolescent scoliotic dancers were more likely to sustain dance injuries than non-scoliotic dancers. This study aimed to investigate the association between scoliosis and dance injury among children and adolescent recreational dancers. Identical web-based and paper-based questionnaires were distributed to children and adolescent recreational dancers to collect demographic information, dance experiences, history and location of dance injuries, as well as the frequency of dance injury in the last 12 months. The prevalence rates of the top three dance injury sites (lower back, knee, and ankles) were estimated. Associations between the presence of scoliosis and various dance injuries in the last 12 months were evaluated by multivariate logistic regression. Data from 704 respondents (644 females, 13.3 ± 2.4 years) was analyzed. Ninety-one respondents (12.9%) reported scoliosis and 11 respondents (1.6%) were wearing scoliosis braces. The 12-month prevalence rates of lumbar, knee, and ankle injuries in scoliotic dancers (24.2%, 22.2%, and 28.5%, respectively) were significantly higher than those of non-scoliotic dancers (10.4%, 14.9%, and 14.8%, respectively). Scoliosis was an independent risk factor for lumbar spine injury (Odds ratio, OR = 2.7), knee injury (OR = 2.6), and multi-site dance-related injury (OR = 1.9). Given the observed strong associations between scoliosis and lumbar or knee dance injuries in the current study, future studies are warranted to investigate the underlying causes.

Timely Revisit of Proprioceptive Deficits in Adolescent Idiopathic Scoliosis: A Systematic Review and Meta-Analysis.

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVES: The present review aimed to summarize the evidence regarding differences in proprioception between children with and without adolescent idiopathic scoliosis (AIS). METHODS: Seven electronic databases were searched from their inception to April 10, 2021. Articles were included if they involved: (1) AIS patients aged between 10 and 18 years, (2) measurements of proprioceptive abilities, and (3) comparisons with non-AIS controls. Animal studies, case reports, commentaries, conference proceedings, research protocols, and reviews were excluded. Two reviewers independently conducted literature screening, data extraction, risks of bias assessments, and quality of evidence evaluations. Relevant information was pooled for meta-analyses. RESULTS: From 432 identified citations, 11 case-control studies comprising 1121 participants were included. The meta-analyses showed that AIS participants displayed proprioceptive deficits as compared to non-AIS controls. Moderate evidence supported that AIS participants showed significantly larger repositioning errors than healthy controls (pooled mean difference = 1.27 degrees, P < .01). Low evidence substantiated that AIS participants had significantly greater motion detection threshold (pooled mean difference = 1.60 degrees, P < .01) and abnormal somatosensory evoked potentials (pooled mean difference = .36 milliseconds, P = .01) than non-AIS counterparts. CONCLUSIONS: Consistent findings revealed that proprioceptive deficits occurred in AIS patients. Further investigations on the causal relationship between AIS and proprioception, and the identification of the subgroup of AIS patients with proprioceptive deficit are needed.

Demographic, Surgical, and Radiographic Risk Factors for Symptomatic Adjacent Segment Disease After Lumbar Fusion: A Systematic Review and Meta-Analysis.

BACKGROUND: Although multiple studies have investigated risk factors for symptomatic adjacent segment disease (ASD) after lumbar fusion, their findings were diverse and inconsistent. This review aimed to summarize risk factors for ASD in order to guide the management of ASD and future research. METHODS: Six electronic databases were systematically searched from inception to December 2019. Two reviewers independently screened titles, abstracts, and full-text articles to identify studies investigating risk factors for ASD after lumbar fusion in humans. The methodological quality of the included studies and the strength of evidence regarding risk factors were evaluated. RESULTS: Sixteen studies involving 3,553 patients were included. Meta-analyses revealed that high body mass index, facet joint violation, anterior shift of the preoperative and postoperative lumbosacral sagittal plumb line, decreased preoperative and postoperative lumbar lordosis, preoperative adjacent disc degeneration, decreased preoperative adjacent disc height, increased postoperative lumbopelvic mismatch, postoperative pelvic incidence, and postoperative pelvic tilt were significantly related to ASD. CONCLUSIONS: This meta-analysis addressed the limitations of prior reviews and summarized evidence with regard to risk factors for ASD following lumbar fusion. Future prospective studies should investigate whether modification of these risk factors can reduce the ASD development. LEVEL OF EVIDENCE: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Improving the improvisational pelvic circumferential compression technique for open-book pelvic fractures using a simulation model and a sphygmomanometer.

BACKGROUND: Open-book pelvic fractures are associated with significant mortality. Emergency management may require a commercial pelvic circumferential compression device to reduce the fracture and compress haemorrhaging pelvic vasculature. Standard, commercial, twin-sized bedsheets are acceptable should commercial devices be unavailable. However, obese victims or personnel with insufficient body strength may impede successful reduction. OBJECTIVE: To demonstrate the value of an improvisational windlass (intravenous pole) in improving the ability to reduce an open-book pelvic fracture. METHODS: The Institutional Review Board-approved study involved 28 diverse healthcare students and emergency medicine residents. Each participant's demographic information and physical characteristics were recorded. A METIman was prepared with knee and ankle binding and a sphygmomanometer set at 40 mm Hg placed over the symphysis pubis. Two-person teams were randomly selected to place a bedsheet at greater trochanter level and atop the sphygmomanometer. The bedsheet was secured with maximum effort by the pairs and the pressure recorded. Following this, the pairs inserted an intravenous pole in the knot and torqued the pole to maximum effort and a repeat pressure recorded. RESULTS: The mean increase in pressure using only the bedsheet was 106.43 mm Hg per team. With bedsheet and intravenous pole, the mean pressure increase was 351.79 mm Hg per team. The difference was statistically significant (independent samples t-test: t = 17.177, p < 0.001, 95% CI (216.65 to 274.07 mm Hg). There was no correlation between pressure increases and the individual physical characteristics of the subjects (r = - 0.183, p = 0.352). CONCLUSIONS: Regardless of personnel's physical attributes, the addition of an improvisational windlass to a pelvic circumferential compression bedsheet can improve the ability to reduce an open-book fracture, especially in obese victims.

A new (two-repeat) octapeptide coding insert mutation in Creutzfeldt-Jakob disease.

We report a family in which the proband died of clinically typical, neuropathologically verified Creutzfeldt-Jakob disease; her still-living mother suffers from a progressive dementia of many years' duration, and her maternal grandfather died after a similar illness. The proband, her mother, and two of three young first-degree relatives all have an identical insert mutation in the PRNP gene consisting of a twice-repeated 24-nucleotide sequence in the region between codons 51 and 91.

Familial Creutzfeldt-Jakob disease with a five-repeat octapeptide insert mutation.

We report a familial form of Creutzfeldt-Jakob disease, associated with a unique insert mutation of the PRNP gene in an American family of Ukrainian origin. Ten family members exhibited early age at onset and long-duration illnesses characterized primarily by personality changes, cognitive impairment, and spasticity. The proband, presenting at age 42 years, exhibited a fairly stable, nonprogressive course over 7 years, followed by precipitous decline and death in the eighth year. Other affected family members exhibited marked clinical heterogeneity. Each tested affected member had an insert mutation consisting of five extra octapeptide repeats between codons 51 and 91 of the PRNP gene on chromosome 20. Examination of two autopsy cases showed classic spongiform change, neuronal loss and astrocytosis in one case, and minimal pathologic abnormality in the other case. This report documents a new insert mutation of the PRNP gene, and confirms the early age of onset, characteristically prolonged clinical course, and clinical and pathologic heterogeneity seen in such mutations.

Applied physiology of water-skiing.

Water-skiing is a physically demanding sport involving highly coordinated movements, extreme upper body torques, sustained isometric contractions and near maximal stresses on the anaerobic system. Due to the physical demands of the sport, elite skiers have developed physiological characteristics similar to other elite athletes. However, until recently little research has focused on the kinesiology, physiology and physical conditioning of water-skiing.

Isokinetic strength and body composition of high school wrestlers across age.

The purpose of this study was to determine the changes in body composition as well as absolute and relative isokinetic forearm and leg strength of high school wrestlers across age. One hundred ninety-five wrestlers (means age +/- SD = 16.36 +/- 1.12 yr) volunteered to be measured for strength using a Cybex II dynamometer at 30, 180, and 300 degrees.s-1. In addition, underwater weighing was used to determine body composition characteristics. The subjects were divided into four age groups: group 1 (G1) = 14.17-15.00 yr (N = 20); group 2 (G2) = 15.01-16.00 yr (N = 60); group 3 (G3) = 16.01-17.00 yr (N = 52); and group 4 (G4) = 17.01-18.50 yr (N = 63). One-way ANOVA or ANCOVA with Tukey post hoc comparisons indicated significant (P less than 0.05) changes across age for height, body weight, and fat-free weight, as well as absolute and relative forearm and leg strength. The results of this study indicated that, while a large portion of the improvements in strength across age were associated with increases in lean tissue, there was an additional "age effect" which could not be accounted for by changes in fat-free weight. Although the mechanism responsible for the "age effect" is unclear, it is possible that neural development contributed to the strength increases across age.

Relationship of lumbar strength in shipyard workers to workplace injury claims.

STUDY DESIGN: Strength testing of lumbar extensors of shipyard workers without back injury claims was accomplished to compare isolated lumbar strength with the severity of their workplace physical demands and the incidence of workplace back injury during a 2-year period. OBJECTIVES: To determine if strength is a predictor of workplace injury and if there is a relationship between the physical demands of the job and strength. SUMMARY OF BACKGROUND DATA: The role of preplacement strength testing has not been clarified as a potential means for predicting workplace injury. It has not been clarified whether work activity affects the strength of the worker. METHODS: One hundred fifty-two shipyard workers were strength tested for isometric lumbar extensor strength. They had been classified as to the severity of their job demands according to the Physical Demand Characteristics. All workers at this industry were likewise classified. Those workers who were tested were followed for 2 years to evaluate for claims of back injury. RESULTS: There was a higher incidence of low back injuries in the heavy and very heavy classification. There was, however, no difference in strength among those workers classified in medium, heavy, and very heavy work. Nine percent of those workers tested had back pains during the following 2 years. All but two had higher-than-average strength. CONCLUSIONS: There is no evidence that preplacement back strength testing would predict workplace claims of injury.

The effect of lumbar belts on isolated lumbar muscle. Strength and dynamic capacity.

STUDY DESIGN: This study analyzed the effect of lumbar support belts on functional performance. OBJECTIVE: To compare lumbar muscle strength and lifting capacity with and without a lumbar belt. SUMMARY OF BACKGROUND DATA: Industrialized settings have begun to encourage the use of lumbar support belts for their employees. It is believed that the belts may decrease the risk of injury and enhance the functional performance of the individual. METHODS: Twenty-two subjects (average age, 27.5 years) were tested on four separate days to evaluate the effect of a commercially available belt on isolated lumbar isometric strength and functional dynamic lifting capacity. All subjects had no history of low back problems. The order of testing with and without a belt was randomized for both conditions. On the first 2 days, subjects performed a seven-angle isometric lumbar extension strength test, 1 day with and 1 day without a lumbar belt. On the following 2 days, subjects were tested to evaluate functional capacity with and without a lumbar belt. The functional capacity evaluation was performed by progressively lifting weighted canisters from various levels. Heart rates were monitored to ensure that a maximum effort was achieved over the different days. RESULTS: T tests revealed that isometric lumbar strength and functional lifting capacity was not significantly affected by the belt. CONCLUSION: The use of a lumbar belt does not enhance isometric lumbar muscle strength or dynamic lifting capacity.

Simultaneous determination of zidovudine and lamivudine in human serum using HPLC with tandem mass spectrometry.

A method employing high performance liquid chromatography (HPLC) with tandem mass spectrometry (MS) has been developed and validated for the simultaneous determination of clinically relevant levels of zidovudine (AZT) and lamivudine (3TC) in human serum. The method incorporates a fully automated ultrafiltration sample preparation step that replaces the solid-phase extraction step typically used for HPLC with UV detection. The calibration range of the dual-analyte LC-MS/MS method is 2.5-2,500 and 2.5-5,000 ng ml-1 for AZT and 3TC, respectively, using 0.25 ml of human serum. The lower limit of quantification was 2.5 ng ml-1 for each analyte, with a chromatographic run time of approximately 6 min. Overall accuracy, expressed as bias, and inter- and intra-assay precision are < +/- 7 and < 10% for AZT, and < +/- 5 and < 12.1% for 3TC over the full concentration ranges. A cross-validation study demonstrated that the LC-MS/MS method afforded equivalent results to established methods consisting of a radioimmuno-assay for AZT and an HPLC-UV method for 3TC. Moreover, the LC-MS/MS was more sensitive, allowed markedly higher-throughput, and required smaller sample volumes (for 3TC only). The validated method has been used to support post-marketing clinical studies for Combivir a combination tablet containing AZT and 3TC.

Pyometra in cats: 183 cases (1979-1984).

Pyometra was diagnosed in 183 cats. The most common signs detected by owners included vaginal discharge, anorexia, and lethargy. Main clinical findings on physical examination were vaginal discharge, abdominal distention, dehydration, palpable uterus, and pyrexia. Abdominal radiography revealed a large uterus in 138/169 cats. Most cats had leukocytosis with a left shift. Diagnosis of pyometra was confirmed at surgery in all cats on the basis of finding a large uterus containing purulent material. Clinical signs resolved in 168 cats after surgery; 15 cats (8%) died or were euthanatized. Postoperative complications in 20% generally resolved within 2 weeks after the cats were sent home. Signs detected by owners and results of physical examination in cats with pyometra were similar, but not as conspicuous as those reported in the dog. Mortality (8%) was similar to that seen in dogs.

Validity and intertester error of anthropometric estimations of body density.

The purposes of this study were to evaluate the intertester error in anthropometry and its effect on estimations of actual body density (ABD), as well as to assess the validity of predicted body density (PBD) from selected anthropometric equation. Sixteen adult males X +/- SD = 21.98 +/- 1.65 years) volunteered to be measured by three experienced and reliable testers at eight circumference, two diameter, and eight skinfold sites as well as by underwater weighing. Eighteen commonly used anthropometric equations which predict body density were selected for evaluation. Repeated measures ANOVA with Tukey post-hoc comparisons were used to determine differences between testers for each anthropometric measure and the PBD values, as well as between the PBD values and ABD. There were significant (p less than 0.01) differences between testers for all anthropometric measures except bi-iliac diameter and hips circumference. However, the magnitude of the differences between testers were considered to be quite small and of no practical concern. There were significant differences among the PBD values and ABD for all equations except the base 10 logarithmic transformations of Durnin and Womersley. Seven of the equations, however, resulted in a constant error of less than or equal to 0.0085 g.ml-1. Overall, there was no single anthropometric equation which satisfied all of the cross-validation criteria suggested by previous investigators, however the linear equation of Forsyth and Sinning which included the scapular and abdominal skinfolds, as well as the bitrochanteric diameter resulted in an extremely small constant error (0.0024 g.ml-1) and an appropriate standard deviation of the PBD values (0.0127 g.ml-1).

Professional practice of pediatric nurse practitioners: implications for education and training of PNPs.

INTRODUCTION: The purpose of this study was to describe the characteristics of employment, the characteristics of children served, and the role functions of recent graduates of pediatric nurse practitioner (PNP) programs and to compare these characteristics across programs. METHOD: A 60-item multiple-choice survey tool was sent to graduates from 1996-1998 of 6 universities across the United States. RESULTS: A total of 137 surveys were received for a return rate of 52%. Less than half of the respondents (44%) indicated that they were employed in a primary care practice. Seventy percent indicated they "often" or "sometimes" provided care to children with acute/critical conditions, and 77% reported caring for children with chronic conditions. Role functions of case management, staff development, consultation, administration, and implementation of research were performed "often" or "sometimes" by more than 50% of respondents. Findings were fairly consistent in 5 out of 6 programs surveyed. DISCUSSION: Graduates of PNP programs are increasingly called on to provide care to children with complex health care needs in non-primary care settings. Role functions beyond the traditional areas required for pediatric primary care are now common practice. Educational programs should address these dynamic changes by assessing the adequacy of their curricula and clinical residencies in preparing graduates.
