Clinical Faculty Orientation Practices in the United States: A Descriptive Study.

BACKGROUND: Due to the nursing faculty shortage, expert clinical nurses are working as novice clinical instructors (CIs). Orientation is needed to prepare these nurses to teach; however, lack of evidence-based guidelines for orientation programs can lead to variability among institutions. PURPOSE: The purpose of this study was to describe clinical nursing faculty orientation practices in the United States. METHODS: A descriptive convergent mixed methods design was used. RESULTS: One hundred thirteen CIs participated. Of these, 70.8% were not provided with a formal orientation to their role. Duration, modality, and content varied widely among orientations. Four themes were derived from the qualitative data: Administrative Requirements, Transition to Clinical Educator, Mentorship, and Resilience. CONCLUSIONS: Clinical faculty orientation practices vary widely in the United States. Evidence-based guidelines are needed to streamline orientations to provide CIs with the requisite knowledge and skills to support clinical students.

A Qualitative Assessment of the Experiences with Eye Health and Barriers to Eyeglasses among U.S. Youth.

SIGNIFICANCE: Uncorrected refractive error is the main cause of visual impairment in U.S. youth and has profound impacts on individuals and society. Identifying and addressing barriers to eyeglasses in this population are critical to maximize youth academic performance, workplace productivity, and quality of life. PURPOSE: We aimed to understand youth experiences with eye health, assess the value that youth place on vision, and identify barriers to refractive correction directly from a nationwide sample of youth to inform interventions to address uncorrected refractive error in this population. METHODS: An open-ended poll was distributed to the MyVoice Text Message Cohort of U.S. youth eliciting youth experiences with eye health and barriers to wearing eyeglasses. Text message responses were coded using grounded theory. RESULTS: Of 1204 recipients, 88.3% (n = 1063) responded. The mean age ± standard deviation was 20.3 ± 2.4 years, 58.8% (n = 625) were male, 74.0% (n = 787) were White, and 41.4% (n = 440) reported low socioeconomic status. Four major themes emerged from the open-ended responses: (1) many youth have experienced problems with their eyes or eyesight (n = 699 [65.8%]); (2) many youth value their eyesight highly (n = 905 [85.1%]; e.g., "Eyesight is one of the most important aspects of my health, particularly in our digital world…"); (3) common reasons youth might not wear glasses even if they need them include concerns over appearance (n = 553 [52.0%]; e.g., "I thought every pair made me look ugly…"), cost (n = 171 [16.1%]), inconvenience (n = 166 [15.6%]), and discomfort (n = 104 [9.8%]); and (4) youth are open to purchasing eyeglasses online (n = 539 [50.7%]). CONCLUSIONS: Appearance, cost, inconvenience, and discomfort are critical barriers to wearing eyeglasses among U.S. youth. A multisectoral response is necessary to address these barriers.

Potentially curative resection of an abdominal wall metastasis from pancreatic adenocarcinoma: a case report.

Pancreatic cancer has a low survival rate even after ostensible complete resection, and treatment for recurrence is usually only palliative. However, rare solitary metastasis can occur and may be operable. In this report, we describe such a case and review the literature on metastasectomy for pancreatic adenocarcinoma. A 66-year-old female underwent Whipple procedure at our institution in 2014 for a pT3N0 pancreatic adenocarcinoma. A slowly growing umbilical mass was noted 6 years later with concomitant rise in her CA 19-9 levels. CT-guided biopsy of her abdominal wall mass confirmed a well-differentiated adenocarcinoma consistent with her primary pancreatic cancer. The patient underwent metastasectomy of the isolated abdominal wall mass, with negative margins. She received no further postoperative treatment. The patient remains disease and symptom-free over 18 months after resection of the metastasis. In highly selected cases of pancreatic adenocarcinoma, resection of solitary metastasis may be therapeutic.

Parkinson's Disease Medication Administration During a Care Transition: The Impact of Interprofessional Team Simulation on Student Competency, Comfort, and Knowledge.

AIM: This study investigated the impact of an interprofessional mock code on students' comfort and competency related to Parkinson's disease (PD) medication administration during care transitions. BACKGROUD: Patients with PD are at increased risk for medication errors during hospitalization. Individualization of PD medication creates vulnerability during care transitions. METHOD: Four interprofessional groups took part in this study: baccalaureate degree senior nursing students (n = 113), master's level nurse anesthesia students (n = 35), doctor of osteopathic medicine fourth-year students (n = 32), and doctor of clinical psychology fourth-year students (n = 22). Groups participated in an unfolding case study simulation involving a mock code with a focus on the omission of time-sensitive PD medication. Pre- and postsimulation test results were compared. RESULTS: Findings indicated an increased understanding among three of the four groups relating to medication timing during care transitions. CONCLUSION: All groups improved with respect to perceived comfort and competency.

Human Milk Cessation in the NICU in Infants with Bronchopulmonary Dysplasia.

OBJECTIVE: The objective of this study was to identify factors associated with the cessation of human milk prior to neonatal intensive care unit (NICU) discharge for infants diagnosed with bronchopulmonary dysplasia (BPD). STUDY DESIGN: Participants were recruited from the Johns Hopkins BPD Clinic between January 2016 and October 2018. Clinical and demographic characteristics were analyzed based on whether participants stopped human milk before or after NICU discharge. RESULTS: Of the 224 infants included, 109 (48.7%) infants stopped human milk prior to discharge. The median duration of human milk intake was less for infants who stopped human milk prior to discharge compared with those who continued after discharge (2 vs. 8 months, p < 0.001). In multivariate regression analysis, pulmonary hypertension (odds ratio [OR]: 2.90; p = 0.016), public insurance (OR: 2.86; p < 0.001), and length of NICU admission (OR: 1.26 per additional month; p = 0.002) were associated with human milk cessation prior to NICU discharge. CONCLUSION: Infants with BPD who have severe medical comorbidities and markers of lower socioeconomic status may be at higher risk for earlier human milk discontinuation. KEY POINTS: · Half of infants in our study with BPD who received human milk stopped human milk prior to NICU discharge.. · For infants on human milk after discharge, the duration of human milk intake was 8.6 months.. · Infants with pulmonary hypertension, tracheostomies, and ventilation stopped human milk earlier.. · Non-White race, lower income, and public insurance were predictors of early human milk cessation..

Impact of a Fruit and Vegetable Prescription Program on Health Outcomes and Behaviors in Young Navajo Children.

BACKGROUND: Rates of childhood obesity are higher in American Indian and Alaska Native populations, and food insecurity plays a major role in diet-related disparities. To address this need, local healthcare providers and a local nonprofit launched the Navajo Fruit and Vegetable Prescription (FVRx) Program in 2015. Children up to 6 y of age and their caregivers are enrolled in the 6-mo program by healthcare providers. Families attend monthly health coaching sessions where they receive vouchers redeemable for fruits, vegetables, and healthy traditional foods at retailers participating in the FVRx program. OBJECTIVES: We assessed the impact of a fruit and vegetable prescription program on the health outcomes and behaviors of participating children. METHODS: Caregivers completed voluntary surveys to assess food security, fruit and vegetable consumption, hours of sleep, and minutes of physical activity; healthcare providers also measured children's body mass index [BMI (kg/m2)] z score at initiation and completion of the program. We calculated changes in health behaviors, BMI, and food security at the end of the program, compared with baseline values. RESULTS: A total of 243 Navajo children enrolled in Navajo FVRx between May 2015 and September 2018. Fruit and vegetable consumption significantly increased from 5.2 to 6.8 servings per day between initiation and program completion (P < 0.001). The proportion of participant households reporting food insecurity significantly decreased from 82% to 65% (P < 0.001). Among children classified as overweight or obese at baseline, 38% achieved a healthy BMI z score at program completion (P < 0.001). Sixty-five percent of children were retained in the program. CONCLUSIONS: The Navajo FVRx program improves fruit and vegetable consumption among young children. Children who are obese or overweight may benefit most from the program.

A Case of a 15-Month-Old With Periorbital Edema and Severe Anemia.

This is the case of a previously healthy 15-month-old girl who initially presented to her primary pediatrician with a 2-week history of intermittent periorbital edema. The edema had improved by the time of the visit, and a urine specimen was unable to be obtained in the clinic. A routine fingerstick demonstrated anemia to 8.8 mg/dL, so the patient was started on ferrous sulfate. She then returned to the emergency department 1 month later with severe periorbital edema and pallor but no other significant symptoms. On physical examination, she was tachycardic with striking periorbital edema and an otherwise normal physical examination. She was noted to have a severe microcytic anemia (hemoglobin of 3.9 mg/dL and mean corpuscular volume of 53.1 fL) and hypoalbuminemia (albumin of 1.9 g/dL and total protein of 3.3 g/dL). The remainder of her electrolytes and liver function test results were within normal limits. A urinalysis was sent, which was negative for protein. Our panel of experts reviews her case to determine a unifying diagnosis for both her severe anemia and her hypoalbuminemia.

Impact of breast milk on respiratory outcomes in infants with bronchopulmonary dysplasia.

BACKGROUND: The objective of our study was to examine whether outpatient respiratory morbidities in infants with bronchopulmonary dysplasia (BPD) are influenced by the human milk consumption. METHODS: Caregivers of subjects recruited from a BPD clinic completed questionnaires regarding breast milk intake and respiratory outcomes. RESULTS: One-hundred eighty-eight caregivers completed the questionnaire. Of these, 173 (92.0%) reported that the child received some breast milk. Infants who received breast milk for fewer months were more likely to be non-white, and have a lower household income, public insurance, and secondhand smoke exposure. A longer receipt of breast milk was associated with reduced likelihoods of emergency department visits, systemic steroid courses, and cough or chest congestion, and a trend towards a lower risk of re-hospitalizations. CONCLUSIONS: Longer duration of breast milk intake was associated with markers of higher socio-economic status, and reduced likelihood of acute and chronic respiratory morbidities among preterm infants with bronchopulmonary dysplasia.

Common and differential transcriptional responses to different models of traumatic stress exposure in rats.

The effect of six different traumatic stress protocols on the transcriptome of the rat adrenal gland was examined using RNA sequencing. These protocols included chronic variable stress, chronic shock, social defeat and social isolation. The response of the transcriptome to stress suggested that there are genes that respond in a universal or stress modality-independent manner, as well as genes that respond in a stress modality-specific manner. Using a small number of the genes selected from the modality-independent set of stress-sensitive genes, a sensitive and robust measure of chronic stress exposure was developed. This stress-sensitive gene expression (SSGE) index could detect chronic traumatic stress exposure in a wide range of different stress models in a manner that was relatively independent of the modality of stress exposure and that paralleled the intensity of stress exposure in a dose-dependent manner. This measure could reliably distinguish control and stressed individuals in the case of animals exposed to the most intense stress protocols. The response of a subset of the modality-specific genes could also distinguish some types of stress exposure, based solely on changes in the pattern of gene expression. The results suggest that it is possible to develop diagnostic measures of traumatic stress exposure based solely on changes in the level of expression of a relatively small number of genes.

Acute and Chronic Increases of Circulating FSTL1 Normalize Energy Substrate Metabolism in Pacing-Induced Heart Failure.

BACKGROUND: FSTL1 (follistatin-like protein 1) is an emerging cardiokine/myokine that is upregulated in heart failure (HF) and is found to be cardioprotective in animal models of cardiac injury. We tested the hypothesis that circulating FSTL1 can affect cardiac function and metabolism under baseline physiological conditions and in HF. METHODS AND RESULTS: FSTL1 was acutely (10 minutes) or chronically (2 weeks) infused to attain clinically relevant blood levels in conscious dogs with cardiac tachypacing-induced HF. Dogs with no cardiac pacing and FSTL1 infusion served as control. 3H-oleate and 14C-glucose were infused to track the metabolic fate of free fatty acids and glucose. Cardiac uptake of lactate and ketone bodies and systemic respiratory quotient were also measured. HF caused a shift from prevalent cardiac and systemic fat to carbohydrate oxidation. Although acute FSTL1 administration caused minimal hemodynamic changes at baseline, in HF dogs it enhanced cardiac oxygen consumption and transiently reversed the changes in free fatty acid and glucose oxidation and systemic respiratory quotient. In HF, chronic FSTL1 infusion stably normalized cardiac free fatty acid, glucose, ketone body consumption, and systemic respiratory quotient, while moderately improving diastolic and contractile function. Consistently, FSTL1 prevented the downregulation of medium-chain acyl-CoA dehydrogenase-a representative enzyme of the free fatty acid oxidation pathway. Complementary in vitro experiments in primary cardiac and skeletal muscle myocytes showed that FSTL1 stimulated oxygen consumption through AMPK (AMP-activated kinase) activation. CONCLUSIONS: These findings support a novel function for FSTL1 and provide the first direct evidence that a circulating cardiokine/myokine can alter myocardial and systemic energy substrate metabolism, in vivo.

Structure and metal binding properties of ZnuA, a periplasmic zinc transporter from Escherichia coli.

ZnuA is the periplasmic Zn(2+)-binding protein associated with the high-affinity ATP-binding cassette ZnuABC transporter from Escherichia coli. Although several structures of ZnuA and its homologs have been determined, details regarding metal ion stoichiometry, affinity, and specificity as well as the mechanism of metal uptake and transfer remain unclear. The crystal structures of E. coli ZnuA (Eco-ZnuA) in the apo, Zn(2+)-bound, and Co(2+)-bound forms have been determined. ZnZnuA binds at least two metal ions. The first, observed previously in other structures, is coordinated tetrahedrally by Glu59, His60, His143, and His207. Replacement of Zn(2+) with Co(2+) results in almost identical coordination geometry at this site. The second metal binding site involves His224 and several yet to be identified residues from the His-rich loop that is unique to Zn(2+) periplasmic metal binding receptors. Electron paramagnetic resonance and X-ray absorption spectroscopic data on CoZnuA provide additional insight into possible residues involved in this second site. The second site is also detected by metal analysis and circular dichroism (CD) titrations. Eco-ZnuA binds Zn(2+) (estimated K (d) < 20 nM), Co(2+), Ni(2+), Cu(2+), Cu(+), and Cd(2+), but not Mn(2+). Finally, conformational changes upon metal binding observed in the crystal structures together with fluorescence and CD data indicate that only Zn(2+) substantially stabilizes ZnuA and might facilitate recognition of ZnuB and subsequent metal transfer.
