Effect of Preclinical Simulation on Family Nurse Practitioner Student’s Readiness for Practice

This project aimed to enhance clinical education preparation in a family nurse practitioner graduate program in rural central Appalachian by providing a psychomotor skills-based simulation with the use of the defusing, discovering, and deepening (3D) debriefing method. The students were surveyed after graduation to determine effectiveness. Program outcomes to measure readiness to practice were graduation, employment, and certification rates. The postgraduation surveys indicated the simulation contributed to an increase in psychomotor skill performance, practicing safe patient care, and making independent decisions in practice. Common themes emerged of feeling “prepared for practice” and being “more marketable” with the procedural skills learned in the simulation.     

Organization of the 43rd European Congress of Cytology in the SARS–CoV-2 pandemic period: A report

The 43rd European Congress of Cytology in Wrocław, Poland, was held as a hybrid meeting in the Fall of 2021. After nearly 2 years without in-person cytology conferences, the 43rd Congress represents 1 of the first major international scientific meetings to occur during the severe acute respiratory syndrome-coronavirus 2 pandemic. Since March 2020, the pandemic situation substantially modified the organization of scientific meetings because of both domestic and international travel restrictions, new health standards, and concern among participants, resulting in new alternative forms of virtual conferencing.

Incidence and risk factors for Chyle leak after pancreatic surgery for cancer: A comprehensive systematic review

BackgroundChyle leak (CL) is a clinically relevant complication after pancreatectomy. Its incidence and the associated risk factors are ill defined, and various treatments options have been described. There is no consensus, however, regarding optimal management. The present study aims to systematically review the literature on CL after pancreatectomy.MethodsA systematic review from PubMed, Scopus and Embase database was performed. Studies using a clear definition for CL and published from January 2000 to January 2021 were included. The PRISMA guidelines were followed during all stages of this systematic review. The MINORS score was used to assess methodological quality.ResultsLiterature search found 361 reports, 99 of which were duplicates. The titles and abstracts of 262 articles were finally screened. The references from the remaining 181 articles were manually assessed. After the exclusions, 43 articles were thoroughly assessed. A total of 23 articles were ultimately included for this review. The number of patients varied from 54 to 3532. Incidence of post pancreatectomy CL varied from 1.3% to 22.1%. Main risk factors were the extent of the surgery and early oral or enteral feeding. CL dried up spontaneously or after conservative management within 14 days in 53% to 100% of the cases.ConclusionsThe extent of surgery is the most common predictor of risk of CL. Conservative treatment has been shown to be effective in most cases and can be considered the treatment of choice. We propose a management algorithm based on the current available evidence.     

Validation of donor fraction cell-free DNA with biopsy-proven cardiac allograft rejection in children and adults

ObjectivesDonor-specific cell-free DNA shows promise as a noninvasive marker for allograft rejection, but as yet has not been validated in both adult and pediatric recipients. The study objective was to validate donor fraction cell-free DNA as a noninvasive test to assess for risk of acute cellular rejection and antibody-mediated rejection after heart transplantation in pediatric and adult recipients.MethodsPediatric and adult heart transplant recipients were enrolled from 7 participating sites and followed for 12 months or more with plasma samples collected immediately before all endomyocardial biopsies. Donor fraction cell-free DNA was extracted, and quantitative genotyping was performed. Blinded donor fraction cell-free DNA and clinical data were analyzed and compared with a previously determined threshold of 0.14%. Sensitivity, specificity, negative predictive value, positive predictive value, and receiver operating characteristic curves were calculated.ResultsA total of 987 samples from 144 subjects were collected. After applying predefined clinical and technical exclusions, 745 samples from 130 subjects produced 54 rejection samples associated with the composite outcome of acute cellular rejection grade 2R or greater and pathologic antibody-mediated rejection 2 or greater and 323 healthy samples. For all participants, donor fraction cell-free DNA at a threshold of 0.14% had a sensitivity of 67%, a specificity of 79%, a positive predictive value of 34%, and a negative predictive value of 94% with an area under the curve of 0.78 for detecting rejection. When analyzed independently, these results held true for both pediatric and adult cohorts at the same threshold of 0.14% (negative predictive value 92% and 95%, respectively).ConclusionsDonor fraction cell-free DNA at a threshold of 0.14% can be used to assess for risk of rejection after heart transplantation in both pediatric and adult patients with excellent negative predictive value.     

Clinical implications of additional posterior fractures in combined anterior-posterior pelvic ring fractures in elderly patients

ObjectivesHistorically, pelvic ring fractures (PRF) are considered to occur predominantly in the anterior ring and therfore to be mechanically stable. Combined anterior and posterior (A + P) PRF are expected to be less mechanically stable and therefore to be associated with higher levels of pain and reduced mobility compared to isolated anterior fractures. The current study investigates the clinical relevance of combined A + P PRF in elderly patients.MethodsA prospective multicentre cohort study was conducted in patients >70 years of age with anterior PRF after low-energy trauma diagnosed on conventional radiographs. All patients underwent an additional CT-scan. Patients were divided into two groups; isolated anterior or combined A + P fractures. Patients were treated conservatively with adequate analgesia for at least one week. If patients could not be mobilised after conservative treatment, surgical fixation was performed. Numerical Rating Scale (NRS) pain scores, dependence on walking aids and Activities of Daily Living scores (ADL) were measured at 2–4 weeks, and 3, 6 and 12 months after fracture.Results102 patients (age 81.1 ± 7.6 years) were included. Isolated anterior fractures were diagnosed in 25 (24.5%) and A + P fractures in 77 (75.5%) patients. Baseline characteristics did not differ between the two groups. Most patients were successfully treated conservatively and 5 (4.9%) underwent percutaneous trans-iliac, trans-sacral screw fixation after failure of conservative treatment. At 2–4 weeks post trauma, patients with A + P fractures had similar median pain scores (3 (range 0–8) vs. 5 (0–10), p = 0.19) and ADL scores (85 (25–100) vs. 78.6 (5–100), p = 0.67), but were more dependent on walking aids (92.8% vs. 72.2%; p = 0.02) compared to patients with isolated anterior fractures. There were no significant differences at 3 months. At one year follow-up the median NRS pain and ADL scores for both fracture groups were 0 and 100, respectively. Mortality was 10.8%, and additional loss to follow-up was 17.6%.ConclusionsThe vast majority of elderly patients with PRF have combined A + P fractures. The clinical implications of additional posterior pelvic ring fractures in elderly patients appears to be limited.
