RESUMEN

INTRODUCTION: Thermal injuries are caused by exposure to a wide variety of agents including heat, electricity, radiation, chemicals, and friction. Early intervention can decrease injury severity by preventing excess inflammation and mitigating burn wound progression for improved healing outcomes. Previous studies have demonstrated that cannabinoids can trigger anti-inflammatory responses and promote wound closure. Therefore, the purpose of this study was to investigate whether a topical application of Noneuphoric Phytocannabinoid Elixir 14 (NEPE14) containing a full complement of phytocannabinoids (< 0.3% delta-9-tetrahydrocannabinol or cannabidiol) and other phytochemicals would mitigate burn wound progression in the treatment of deep partial-thickness burn wounds. METHODS: Deep partial-thickness burns were created on the dorsum of four anesthetized pigs and treated with NEPE14, Vehicle control, Silverlon, or gauze. The burns were assessed on postburn days 4, 7, and 14. Assessments consisted of digital photographs, Laser-Speckle imagery (blood perfusion), MolecuLight imagery (qualitative bacterial load), and biopsies for histology and immunohistochemistry (interleukin six and tumor necrosis factor-α). RESULTS: Topical treatment with NEPE14 significantly (P < 0.001) decreased inflammation (interleukin six and tumor necrosis factor-α) in comparison to control groups. It was also demonstrated that the reduction in inflammation led to mitigation of burn wound progression. In terms of wound healing and presence of bacteria, no statistically significant differences were observed. CONCLUSIONS: Topical treatment of deep partial-thickness burns with NEPE14 decreased wound inflammation and mitigated burn wound progression in comparison to control treatments.

RESUMEN

PURPOSE: To describe a program for post-graduate education of urologists providing urologic ultrasound services. METHODS: A detailed description of the evolution of an educational program developed by the American Urological Association (AUA) Office of Education for providing the knowledge and fundamental skills necessary for urologists to provide high-quality, medically appropriate urologic ultrasound examinations. The structure of the program, as well as the training of instructors and certification of attainment of the goals and skills set forth in the program, is highlighted. Specific recommendations for providing didactic instruction and managing the logistics of the hands-on training are given. RESULTS: Approximately 1700 urologists have received post-graduation instruction in the performance of urologic ultrasound in some form under the auspices of the AUA Office of Education since 1993. The hands-on training course has continued to evolve in response to feedback from the attendees and the ongoing emergence of new clinical indications for urologist-performed ultrasound. A post graduate course, including didactic instruction and hands-on skill training, continues to be in demand and fully subscribed and attended. CONCLUSION: Instruction in the performance of diagnostic ultrasound examinations is not a formal component of many urologic residencies in the United States. Since many ultrasound procedures are being performed by practicing urologists, there is an ongoing need for post-graduate training in urologic ultrasound.

RESUMEN

Objectives: Diet quality often changes as shift workers adjust to atypical work schedules, however, limited research exists examining the early effects of starting rotating shift work on diet and body composition. This study explored dietary behavior changes occurring in graduate paramedics during the first year of exposure to rotating shift work, and investigated dietary intake, diet quality and anthropometric changes over two years.Methods: Participants from a graduate paramedic cohort in Melbourne, Australia were approached after two years of shift work for study inclusion. Using a mixed method study approach, the qualitative component comprised individual in-depth interviews to explore perceived dietary behavior changes experienced over the first year of shift work. Interview transcripts were thematically analyzed and guided by the COM-B model (capability, opportunity, motivation, and behavior) and theoretical domains framework (TDF). Diet quality and dietary intake were quantitatively assessed by the Australian Eating SurveyTM at baseline, one year, and two years, along with body weight, waist circumference, and body mass index (BMI) to monitor changes.Results: Eighteen participants were included in the study. From the interviews, participants reported: 1. food choices are driven by wanting to fit in with coworker food habits, 2. food choices and mealtimes are unpredictable and 3. paramedics try to make healthy food choices but give in to less healthy options. While daily energy intake and diet quality scores did not differ in the first two years of shift work, daily energy from takeaway foods significantly increased (mean difference (MD): 2.96% EI; 95% CI: 0.44 - 5.48; p = 0.017) and increases in weight (MD: 2.96 kg; 95% CI: 0.89-5.04; p = 0.003), BMI (MD: 1.07 kg/m2; 95% CI: 0.26 - 1.87; p = 0.006) and waist circumference (MD: 5.07 cm; 95% CI: 1.25-8.89; p = 0.006) were also evident at two years.Conclusions: This study contributes new information on dietary changes and the current early trajectory of unintentional weight gain and takeaway reliance occurring within a graduate paramedic cohort over two years of shift work. To reduce the unintended metabolic consequences commonly observed with rotating shift schedules, workplaces could improve access to healthier food options and enable behavioral support/education to address nutrition-related health risks.

RESUMEN

BACKGROUND: Evidence-based practices are shown to improve health outcomes in persons with substance use disorder (SUD), but practice adoption is often limited by stigma. Stigma towards these patients leads to poor communication, missed diagnoses, and treatment avoidance. AIMS: The purpose of this study was to survey a rural community to conceptualize knowledge and attitudes towards SUD and opioid use disorder. DESIGN: The study design was cross-sectional survey using a convenience sample in a rural community in southwestern Ohio. METHODS: A 25-item electronic survey was created to assess knowledge and attitudes of the community towards SUD, evidenced-based practices, and stigma. Questions were grouped into five subcategories to meaningfully address high-priority areas. Descriptive statistics included frequencies and percentages. A comparative analysis was performed using Chi-square and phi to evaluate response rates from the first question, A substance use disorder is a real illness like diabetes and heart disease, to the other survey questions. RESULTS: A total of 173 people responded to the survey. The response to "A substance use disorder is a real illness like diabetes and heart disease" resulted in two groups of similar size, with 83 (48.5%) of the respondents agreeing with the statement. There was a significant difference (p < .001) in 15 questions between the two groups. CONCLUSIONS: People who believe SUD is a real illness were more likely to support evidence-based treatment practices, show less stigma towards those suffering from SUD, and support harm reduction services.

RESUMEN

Healthcare providers face certain barriers to fully assessing different social needs and referring patients to community resources appropriately, perpetuating healthcare disparities. The purpose of this quality improvement study was to create an intervention to increase assessment of social determinants of health (SDOH) and referrals. A module incorporating concepts of SDOH was developed and delivered during two training sessions. This module focused on: Partnership, Acceptance, Compassion, and Evocation (PACE). It was found that the public health providers at a local public health center were able to appropriately refer 55% of all new and annual patients screened with specific SDOH needs after the educational module was implemented. An overall increase in SDOH understanding and referrals was also found. SDOH training and ongoing social needs screenings could be incorporated in public health centers to decrease healthcare inequities present among minorities and individuals who live in poverty.

RESUMEN

The ability to provide timely identification of the causative agents of lower respiratory tract infections can promote better patient outcomes and support antimicrobial stewardship efforts. Current diagnostic testing options include culture, molecular testing, and antigen detection. These methods may require collection of various specimens, involve extensive sample treatment, and can suffer from low sensitivity and long turnaround times. This study assessed the performance of the BioFire FilmArray Pneumonia Panel (PN panel) and Pneumonia Plus Panel (PNplus panel), an FDA-cleared sample-to-answer assay that enables the detection of viruses, atypical bacteria, bacteria, and antimicrobial resistance marker genes from lower respiratory tract specimens (sputum and bronchoalveolar lavage [BAL] fluid). Semiquantitative results are also provided for the bacterial targets. This paper describes selected analytical and clinical studies that were conducted to evaluate performance of the panel for regulatory clearance. Prospectively collected respiratory specimens (846 BAL and 836 sputum specimens) evaluated with the PN panel were also tested by quantitative reference culture and molecular methods for comparison. The PN panel showed a sensitivity of 100% for 15/22 etiologic targets using BAL specimens and for 10/24 using sputum specimens. All other targets had sensitivities of ≥75% or were unable to be calculated due to low prevalence in the study population. Specificity for all targets was ≥87.2%, with many false-positive results compared to culture that were confirmed by alternative molecular methods. Appropriate adoption of this test could provide actionable diagnostic information that is anticipated to impact patient care and antimicrobial stewardship decisions.

RESUMEN

BACKGROUND: Management of proctitis refractory to conventional therapies presents a common clinical problem. The use of acetarsol suppositories, which are derived from organic arsenic, was first described in 1965. Data concerning clinical efficacy and tolerability are very limited. AIM: To examine the efficacy of acetarsol suppositories for the treatment of refractory proctitis. METHODS: A retrospective analysis was performed on patients with inflammatory bowel disease treated with acetarsol suppositories between 2008 and 2014 at Addenbrooke's Hospital, Cambridge, United Kingdom. Clinical response was defined as resolution of symptoms back to baseline at the time of next clinic review. RESULTS: Thirty-nine patients were prescribed acetarsol suppositories between March 2008 and July 2014 (29 patients with ulcerative colitis, nine with Crohn's disease, and one with indeterminate colitis). Thirty-eight were included for analysis. The standard dose of acetarsol was 250 mg twice daily per rectum for 4 weeks. Clinical response was observed in 26 patients (68%). Of the 11 patients who had endoscopic assessment before and after treatment, nine (82%) showed endoscopic improvement and five (45%) were in complete remission (Wilcoxon signed-rank test p = 0.006). One patient developed a macular skin rash 1 week after commencing acetarsol, which resolved within 4 weeks of drug cessation. CONCLUSION: Acetarsol was effective for two out of every three patients with refractory proctitis. This cohort had failed a broad range of topical and systemic treatments, including anti-TNFα therapy. Clinical efficacy was reflected in significant endoscopic improvement. Adverse effects of acetarsol were rare.

RESUMEN

OBJECTIVES: The United States is experiencing an opioid overdose crisis. Research suggests prolonged postoperative opioid use, a common complication following surgery, is associated with opioid misuse, which, in turn, is the greatest risk factor of heroin misuse. The objective of this review is to evaluate how postoperative opioid exposure relates to prolonged use and to identify factors that predict prolonged postoperative opioid use. DESIGN: An integrative review of the literature. DATA SOURCES: Electronic and hand searching methods were used in PubMed, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, CINAHL, and SCOPUS. Search terms included opioid, opiate, postoperative pain, drug administration, prescribing pattern, prescription, inappropriate prescribing, self-medication, patient-controlled analgesia, opioid-naïve patients, and prolonged opioid use. REVIEW/ANALYSIS METHODS: Data were synthesized by identifying themes reflecting the results of the review. A quality assessment of the articles was also conducted. RESULTS: Fourteen articles were included and two main themes emerged: (1) Surgery places opioid naïve patients at risk for prolonged opioid use and (2) Certain patient characteristics may be predictive of prolonged postoperative opioid use. CONCLUSIONS: Prolonged postoperative opioid use is related to factors in addition to prescribing practices. Researchers consistently found that patients who are already on opioids, benzodiazepines, or addicted to alcohol; who have mental health disorders, depressive symptoms, or a self-perceived risk of addiction; and patients with multiple co-morbidities are at greater risk of prolonged use; demographics were inconsistent. NURSING IMPLICATIONS: Studies are needed to determine the predicting characteristics of prolonged postoperative opioid use, the type of surgeries that place patients at most risk, and the effect postoperative exposure to opioids has on prolonged use. This information can be used to develop and implement protocols to prevent misuse among high-risk patients.

RESUMEN

BACKGROUND: The evaluation and maintenance of treatment fidelity is an important methodological consideration in intervention research. Treatment fidelity is the degree to which interventions are delivered as outlined by the program developers. A lack of fidelity to the intervention model has the potential to be a large source of error, including type I and type II error. Monitoring and assuring fidelity is critical to assuring the validity of the interventions. The Fidelity Checklist is a reliable and valid tool designed to measure fidelity in a group-based parenting program. The Fidelity Checklist assesses group leaders' maintenance of the intervention protocol (adherence) and their group facilitation and process skills (competence). OBJECTIVES: The purpose of this article is to describe the systematic process of modifying the Fidelity Checklist for use in a community-based opioid overdose prevention group educational intervention. METHODS: A biphasic approach was used to modify the Fidelity Checklist. Phase 1 included engaging key stakeholders during a full-day meeting to determine adherence subscale components. Phase 2 included: (a) the modification of the competence subscale of the Fidelity Checklist, (b) adaptation of the coding manual defining the components of the Fidelity Checklist, and (c) creating a fidelity checklist to guide interventionists. RESULTS: The biphasic systematic modification approach resulted in a revised Fidelity Checklist that was successfully used to measure treatment fidelity in a community-based opioid overdose prevention program. CLINICAL RELEVANCE: The findings of this study provide information for nurse researchers and nurse educators for modifying a fidelity checklist that can be used to enhance community-based educational interventions.

RESUMEN

BACKGROUND: Nationally, overdose fatalities have reached epidemic proportions. Ohio has one of the highest overdose death rates in the country, as well as high rates of prescription opioid trafficking. METHODS: A cross-sectional self-report survey of opioid overdose prevention programs (OOPPs) in Ohio was conducted between August and October 2014 to characterize programs and ascertain barriers to successful implementation. A 91% response rate was achieved with 18 programs participating in the study. RESULTS: The first Ohio OOPP opened in August 2012, a second program opened in 2013, and the remaining programs began in 2014. All of the programs distribute nasal naloxone and provide overdose prevention education, and 89% (n = 16) provide overdose kits for free. Six OOPPs are funded by the Ohio Department of Health, 3 programs are funded by a local health foundation, and several other public and private funding sources were reported. The OOPPs have funding to distribute a combined total of 8,670 overdose kits and had distributed 1998 kits by October 2014. The OOPPs reported 149 overdose reversals. Fifteen programs (83%) reported implementation barriers that were categorized as stigma-, cost-, staffing-, legal, regulatory, and client-related problems. Legislative changes aimed at removing some of the obstacles to distribution and lay administration of naloxone have recently been enacted in Ohio. CONCLUSIONS: OOPPs have rapidly expanded in Ohio during the past 3 years. Although recent legislative changes have addressed some of the reported implementation barriers, stigma and the cost of naloxone remain significant problems.

RESUMEN

BACKGROUND: The rising cost of hospitalizations for heart failure (HF) care mandates intervention models to address education for self-care success. The effectiveness of memory enhancement strategies to improve self-care and learning needs further examination. OBJECTIVE: The objective of this study was to examine the effects of an education-support intervention delivered in the home setting, using strategies to improve health status and self-care in adults/older adults with class I to III HF. Our secondary purpose was to explore participants' subjective perceptions of the intervention. METHODS: This study used a randomized, 2-group design. Fifty people were enrolled for 9 months and tested at 4 time points-baseline; after a 3-month education-support intervention; at 6 months, after 3 months of telephone/e-mail support; and 9 months, after a 3-month period of no contact. Advanced practice registered nurses delivered the intervention. Memory enhancement methods were built into the teaching materials and delivery of the intervention. We measured the intervention's effectiveness on health status outcomes (functional status, self-efficacy, quality of life, emotional state/depressive symptoms, and metamemory) and self-care outcomes (knowledge/knowledge retention, self-care ability). Subjects evaluated the usefulness of the intervention at the end of the study. RESULTS: The mean age of the sample was 62.4 years, with a slight majority of female participants. Participants were well educated and had other concomitant diseases, including diabetes (48%) and an unexpected degree of obesity. The intervention group showed significant improvements in functional status, self-efficacy, and quality of life (Kansas City Cardiomyopathy Questionnaire); metamemory Change and Capacity subscales (Metamemory in Adulthood Questionnaire); self-care knowledge (HF Knowledge Test); and self-care (Self-care in Heart Failure Index). Participants in both groups improved in depressive scores (Geriatric Depression Scale). CONCLUSIONS: An in-home intervention delivered by advanced practice registered nurses was successful in several health status and self-care outcomes, including functional status, self-efficacy, quality of life, metamemory, self-care status, and HF knowledge.

RESUMEN

Numerous bioarcheological investigations have suggested that as agriculture intensifies, levels of physiological stress and poor health increase. However, previous research in Southeast Asia suggests that a decline in health was not universal. This study aimed to provide the first investigation of human health during the intensification of rice agriculture in the large skeletal sample from the prehistoric site of Ban Non Wat, Northeast Thailand (1750-420 b.c.). Health was analysed using two indicators of childhood stress, the prevalence of linear enamel hypoplasia (LEH), a measure of early childhood stress, and stature, as a measure of late childhood stress, were collated for 190 adults. Sex-specific diachronic relationships between the prevalence of LEH and stature were explored. For both sexes, initially the prevalence of LEH was found to decrease and then increase over time. Stature remained constant over time for males, although for females stature increased initially, then decreased. Early childhood stress was not significantly correlated with stature in females (P = 0.185), but high levels of LEH were unexpectedly correlated with taller male stature (P = 0.017). Our findings suggest an initial improvement in health during agricultural intensification at this site, likely related to a reduction in physiological perturbations and maintenance of a nutritious diet during this time. The subsequent deterioration in health may reflect geomorphologically and archaeologically indicated variation in environmental conditions and consequential sociocultural changes. We suggest that the sex-differences in the relationship between stature and LEH may relate to the timing of stress and/or catch-up growth.

RESUMEN

Hyperemesis gravidarum is the most common condition requiring hospital care for women during the first 20 weeks of pregnancy and may lead to malnutrition, dehydration, and vitamin deficiencies. Depletion of vitamins such as thiamine may result in the development of Wernicke encephalopathy, a severe neurological disorder that can increase the risk for mortality and morbidity for the mother and fetus. A lack of awareness regarding the relationship of hyperemesis gravidarum and Wernicke encephalopathy may result in delayed treatment and disease management. Glucose administration in the presence of thiamine deficiency may induce Wernicke encephalopathy; protocols are needed to ensure dextrose is used for women with hyperemesis gravidarum in times of prolonged vomiting and poor oral intake only after first administering thiamine. This article includes a discussion of best practices for thiamine supplementation with hyperemesis gravidarum and Wernicke encephalopathy.

RESUMEN

ABSTRACT: An 85-year-old man with prostate cancer and de novo bone metastases was treated with hormonal therapy with resolution of bone lesions, improved primary disease, and improved serum tumor markers. Although on hormonal therapy, biochemical recurrence prompted performance of 18 F-fluciclovine PET/CT. Fluciclovine PET/CT revealed primary prostate cancer progression with incidental note of avid foci in the colon for which colonoscopy was recommended. Colonoscopy with biopsy was performed with pathology revealing primary colon adenocarcinoma. Before reinitiation of prostate cancer therapy, segmental colon resection was performed with pathology positive for additional sites of colon cancer.

RESUMEN

Critical illness creates challenges for healthcare providers in determining the optimal treatment of severe disease, particularly in determining the most appropriate selection and dosing of medications. Critically ill patients experience endogenous physiologic changes that alter the pharmacokinetics (PKs) of medications. These alterations can be further compounded by mechanical support modalities such as extracorporeal membrane oxygenation (ECMO). Specific components of the ECMO circuit have the potential to affect drug PKs through drug sequestration and an increase in the volume of distribution. Factors related to the medications themselves also play a role. These PK alterations create problems when trying to properly utilize antimicrobials in this patient population. The literature seeking to identify appropriate antimicrobial dosing regimens is both limited and difficult to evaluate due to patient variability and an inability to determine the exact role of the ECMO circuit in reduced drug concentrations. Lipophilic and highly protein bound medications are considered more likely to undergo significant drug sequestration in an ECMO circuit, and this general trend represents a logical starting point in antimicrobial selection and dosing in patients on ECMO support. This should not be the only consideration, however, as identifying infection and evaluating the efficacy of treatments in this population is challenging. Due to these challenges, therapeutic drug monitoring should be utilized whenever possible, particularly in cases with severe infection or high concern for drug toxicity.

RESUMEN

BACKGROUNDWhile the benefits of statin therapy on atherosclerotic cardiovascular disease are clear, patients often experience mild to moderate skeletal myopathic symptoms, the mechanism for which is unknown. This study investigated the potential effect of high-dose atorvastatin therapy on skeletal muscle mitochondrial function and whole-body aerobic capacity in humans.METHODSEight overweight (BMI, 31.9 ± 2.0) but otherwise healthy sedentary adults (4 females, 4 males) were studied before (day 0) and 14, 28, and 56 days after initiating atorvastatin (80 mg/d) therapy.RESULTSMaximal ADP-stimulated respiration, measured in permeabilized fiber bundles from muscle biopsies taken at each time point, declined gradually over the course of atorvastatin treatment, resulting in > 30% loss of skeletal muscle mitochondrial oxidative phosphorylation capacity by day 56. Indices of in vivo muscle oxidative capacity (via near-infrared spectroscopy) decreased by 23% to 45%. In whole muscle homogenates from day 0 biopsies, atorvastatin inhibited complex III activity at midmicromolar concentrations, whereas complex IV activity was inhibited at low nanomolar concentrations.CONCLUSIONThese findings demonstrate that high-dose atorvastatin treatment elicits a striking progressive decline in skeletal muscle mitochondrial respiratory capacity, highlighting the need for longer-term dose-response studies in different patient populations to thoroughly define the effect of statin therapy on skeletal muscle health.FUNDINGNIH R01 AR071263.

RESUMEN

Workers employed in rotating shift schedules are at a higher metabolic risk compared with those in regular day and fixed shift schedules; however, the contribution of diet is unclear. This systematic review aimed to investigate how rotating shift work schedules affect dietary energy intake and dietary patterns compared with regular day and fixed shift schedules. In addition, intraperson energy intake and dietary pattern comparisons within rotating shift schedules were investigated. Database searches were conducted on MEDLINE, Cochrane, CINAHL, PSYCinfo, EMBASE, and Scopus, in addition to manual search of bibliographic references, to identify articles. Two separate meta-analyses compared dietary intake between day work and rotating shift work schedules and within the rotational shift work group (morning/day and night shifts). Differences in dietary patterns were synthesized narratively. Thirty-one studies (n = 18,196 participants) were included in the review, and meta-analyses were conducted with 24-hour mean energy intake data from 18 (n = 16,633 participants) and 7 (n = 327 participants) studies, respectively. The average 24-hour energy intake of rotating shift workers was significantly higher than that of workers in regular daytime schedules [weighted mean difference (WMD): 264 kJ; 95% confidence interval (CI): 70, 458 kJ; P < 0.008; I2 = 63%]. However, the mean difference in 24-hour energy intake between morning/day shifts compared with night shifts within rotational shift schedules was not statistically significant (WMD: 101 kJ; 95% CI: -651, 852 kJ; P = 0.79; I2 = 77%). Dietary patterns of rotating shift workers were different from those of day workers, showing irregular and more frequent meals, increased snacking/eating at night, consumption of fewer core foods, and more discretionary foods. This review highlights that dietary intake in rotational shift workers is potentially higher in calories and features different eating patterns as a consequence of rotating shift work schedules. This review was registered at PROSPERO as ID 182507.

RESUMEN

OBJECTIVES: Quarantine after exposure to COVID-19 has resulted in substantial loss of in-person learning in schools from prekindergarten through grade 12. Test to Stay (TTS), a strategy that limits the spread of SARS-CoV-2 while prioritizing in-person learning, requires substantial investment in resources. The objective of this study was to assess the perceived benefits, barriers, and facilitators of implementing TTS in an urban school district in the Midwest serving primarily Black or African American people with low income. METHODS: In December 2021, we used a concurrent mixed-methods approach to understand perceived benefits, barriers, and facilitators of implementing TTS by combining quantitative analysis of telephone surveys conducted with parents (n = 124) and a qualitative inquiry involving key informants from the school district and local health department (n = 22). We analyzed quantitative data using descriptive statistics. We used thematic analysis to analyze qualitative data. RESULTS: Quantitative findings showed that parents supported TTS because it was convenient (n = 83, 97%) and effective (n = 82, 95%) in keeping students learning in person (n = 82, 95%) and preventing the spread of COVID-19 (n = 80, 93%). Qualitative interviews with informants found that having a clear protocol and assigning staff to specified tasks allowed for successful TTS implementation. However, insufficient staffing and testing resources, parent mistrust of testing, and lack of communication from schools were perceived barriers. CONCLUSION: The school community strongly supported TTS despite the many implementation challenges faced. This study emphasized the importance of ensuring resources for equitable implementation of COVID-19 prevention strategies and the critical role of communication.

RESUMEN

NOVELTY: Caloric restriction and exercise exert significant improvements in cardiac autonomic function as measured by HRV in overweight and obesity. Aerobic exercise training, within recommended guidelines coupled with weight loss maintenance, retains cardiac autonomic function benefits from weight loss in previously obese individuals.
