ABSTRACT

BACKGROUND: Inflammatory bowel disease (IBD) represents a significant burden in the United States. We aim to evaluate disparities in postoperative outcomes among diverse patients undergoing surgery for IBD.

METHODS: The National Inpatient Sample (NIS) (2016-2018) was used to calculate national estimates for a number of postoperative complications in patients with IBD. Statistical analyses were performed using SAS survey procedures when calculating the national estimates.

RESULTS: A majority of the 107,375 patients (weighted) undergoing surgery for IBD were White (81.7%), rather than Black (10.1%) or Hispanic (8.2%). Black patients had higher rates of postoperative infections compared to White or Hispanic patients (4.2% vs. 3.1% vs. 2.7%, P=0.0137). There was a significant difference in morbidity and mortality, with higher rates in Black patients (20.1% vs. 17.1% vs. 17.9%, P=0.0029). Black patients experienced longer average hospital stays compared to White or Hispanic patients (12.6 vs. 9.6 vs. 11.2 days, P<0.001), despite suffering fewer comorbidities (Modified Charlson Index 1.9 vs. 2.3 vs. 2.0, P<0.001).

CONCLUSIONS: This study demonstrated racial disparities in postoperative outcomes, with Black patients experiencing significantly higher rates of postoperative infections, overall morbidity and mortality, and length of stay, despite suffering from fewer comorbidities. This suggests an opportunity to improve equity of care for all patients with IBD by further examining social determinants of health that have not been traditionally studied.

ABSTRACT

BACKGROUND: Endoscopic ultrasound (EUS)-guided transmural drainage using double pigtail plastic stents (DPPS) has been routine for the treatment of peripancreatic fluid collections (PFC). Lumen-apposing metal stents (LAMS) have since their introduction been the preferred choice; however, their superiority has not been proven. The aim of this study was to compare the efficacy and safety of DPPS and LAMS.

METHODS: This was a single-center, prospective study that included consecutive patients undergoing EUS-guided drainage between January 2010 and December 2020. The primary endpoints were technical success, clinical success and adverse event rate, while the secondary endpoints included symptomatic relief, length of hospital stay, and need for adjunct drainage. A subgroup analysis of walled-off necrosis (WON) was performed.

RESULTS: A total of 89 patients (median age 56 years) underwent EUS-guided transmural drainage (DPPS: n=53; LAMS: n=36) because of a pseudocyst (n=37) or a WON (n=52). Both DPPS and LAMS had a 100% technical success rate and a comparable adverse event rate (4% vs. 6%, P=0.24). An equivalent efficacy was recorded for the drainage of PFC comparing DPPS and LAMS, and no significant statistical difference was recorded in clinical success (DPPS 60% vs. LAMS 61%, P=0.94) or the need for reintervention (DPPS 11% vs. LAMS 13%, P=0.72).

CONCLUSIONS: In this large, prospective study of EUS-guided drainage of peripancreatic fluid collections, LAMS and DPPS showed equivalent safety, technical success, clinical success and hospital stay. Both techniques were associated with a comparable need for complementary necrosectomy.

ABSTRACT

BACKGROUND: Malaria vaccine is a potentially effective addition to the armamentarium for malaria control. The candidate RTS,S malaria vaccine has undergone phase III clinical trials and WHO has indicated that a policy recommendation is possible in 2015. Given the delays with adoption of other novel interventions including vaccines, there is a need to ensure that all elements that will inform the decision to adopt a malaria vaccine, including community willingness, will be available on time. This study was carried out to assess the willingness of caregivers of under-5 children to accept a malaria vaccine once available and recommended for use.

MATERIALS AND METHODS: 427 consenting caregivers, selected using a cluster sampling technique, from five communities in Ibadan, Nigeria, participated in a questionnaire. In-depth interviews (IDIs) were conducted among 47 key community members. Data were analysed using descriptive statistics, Chi-square and logistic regression at p≤0.05. Thematic content analysis was used to analyse the transcribed IDI data.

RESULTS: The mean age of survey respondents was 29.8±5.8 years. Only 20.1% of the respondents had ever heard of malaria vaccine; 87.0% showed willingness to accept a malaria vaccine. Reasons stated for not willing included ‘husband did not want immunisation’ (73.6%), ‘felt it might be expensive’ (47.2%) and ‘felt it might paralyse children’ (24.5%). Nearly half (48.7%) of the respondents said that if vaccine is not given orally like polio vaccine it might not be accepted. Influence of community health workers was found to predict willingness to accept a malaria vaccine (OR: 0.316, 95% CI: 0.142-0.705). IDI participants were favourably disposed to introduction of a vaccine against malaria, although they had concerns about the formulation of the vaccine and possible adverse events.

CONCLUSION: Well-designed communication strategies implemented prior to the introduction of a malaria vaccine would be essential to foster a supportive environment for eventual adoption and acceptance thereof.

ABSTRACT

OBJECTIVES: Androgen deprivation therapy (ADT), a common treatment for prostate cancer, has debilitating impacts on physical and psychological quality of life. While some interventions focus on managing the physical side effects of ADT, there is a paucity of interventions that also address psychosocial and educational needs. The objective of this systematic review was to identify psychological and educational survivorship interventions targeting health-related quality of life (HRQoL) outcomes in men on ADT.

DESIGN: A systematic review of randomised controlled trials.

DATA SOURCES: Web of Science, Cochrane, EBSCO Host, PubMed, SCOPUS from inception (1984) to 28 January 2023.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Psychological and/or educational survivorship interventions targeting HRQoL outcomes for men on ADT; minimum 80% of participants on ADT; used a validated HRQoL outcome measure; published in English in a peer-reviewed journal.

DATA EXTRACTION AND SYNTHESIS: Data extraction using pre-specified study criteria was conducted. Heterogeneity of eligible studies precluded a meta-analysis.

RESULTS: A total of 3381 publications were identified with eight meeting the criteria. Interventions were either psychological with a cognitive behavioural approach (n=4), or educational with (n=2) or without (n=2) psychoeducational components.Two studies reported a statistically significant improvement using a specific HRQoL measure. Most studies were not adequately powered and/or included small sample sizes limiting the conclusions that can be drawn on effectiveness. The most effective interventions were (i) individually based, (ii) educational with a psychoeducational component, (iii) supplemented with information packages and/or homework and (iv) included personalised needs assessments.

CONCLUSION: There is a paucity of literature reporting psychological and educational survivorship interventions targeting HRQoL outcomes for men on ADT. What is urgently needed are person-centred survivorship interventions that are flexible enough to identify and address individual needs, taking into account the impact ADT has on both physical and psychological quality of life.

ABSTRACT

INTRODUCTION: Knee osteoarthritis (OA) is the most prevalent arthritis type and a leading cause of chronic mobility disability. While pain medications provide only symptomatic pain relief; growing evidence suggests pentosan polysulfate sodium (PPS) is chondroprotective and could have anti-inflammatory effects in knee OA. This study aims to explore the efficacy and safety of oral PPS in symptomatic knee OA with dyslipidaemia.

METHODS AND ANALYSIS: MaRVeL is a phase II, single-centre, parallel, superiority trial which will be conducted at Royal North Shore Hospital, Sydney, Australia. 92 participants (46 per arm) aged 40 and over with painful knee OA and mild to moderate structural change on X-ray (Kellgren and Lawrence grade 2 or 3) will be recruited from the community and randomly allocated to receive two cycles of either oral PPS or placebo for 5 weeks starting at baseline and week 11. Primary outcome will be the 16-week change in overall average knee pain severity measured using an 11-point Numeric Rating Scale. Main secondary outcomes include change in knee pain, patient global assessment, physical function, quality of life and other structural changes. A biostatistician blinded to allocation groups will perform the statistical analysis according to the intention-to-treat principle.

ETHICS AND DISSEMINATION: The protocol has been approved by the NSLHD Human Research Ethics Committee (HREC) (2021/ETH00315). All participants will provide written informed consent online. Study results will be disseminated through conferences, social media and academic publications.

ABSTRACT

BACKGROUND: Neonates with immature auditory function (eg, weak/absent middle ear muscle reflex) could conceivably be vulnerable to noise-induced hearing loss; however, it is unclear if neonates show evidence of hearing loss following MRI acoustic noise exposure.

PURPOSE: To explore the auditory effects of MRI acoustic noise in neonates.

STUDY TYPE: Prospective.

SUBJECTS: Two independent cohorts of neonates (N = 19 and N = 18; mean gestational-age, 38.75 ± 2.18 and 39.01 ± 1.83 weeks).

FIELD STRENGTH/SEQUENCE: T1-weighted three-dimensional gradient-echo sequence, T2-weighted fast spin-echo sequence, single-shot echo-planar imaging-based diffusion-tensor imaging, single-shot echo-planar imaging-based diffusion-kurtosis imaging and T2-weighted fluid-attenuated inversion recovery sequence at 3.0 T.

ASSESSMENT: All neonates wore ear protection during scan protocols lasted ~40 minutes. Equivalent sound pressure levels (SPLs) were measured for both cohorts. In cohort1, left- and right-ear auditory brainstem response (ABR) was measured before (baseline) and after (follow-up) MRI, included assessment of ABR threshold, wave I, III and V latencies and interpeak interval to determine the functional status of auditory nerve and brainstem. In cohort2, baseline and follow-up left- and right-ear distortion product otoacoustic emission (DPOAE) amplitudes were assessed at 1.2 to 7.0 kHz to determine cochlear function.

STATISTICAL TEST: Wilcoxon signed-rank or paired t-tests with Bonferroni’s correction were used to compare the differences between baseline and follow-up ABR and DPOAE measures.

RESULTS: Equivalent SPLs ranged from 103.5 to 113.6 dBA. No significant differences between baseline and follow-up were detected in left- or right-ear ABR measures (P > 0.999, Bonferroni corrected) in cohort1, or in DPOAE levels at 1.2 to 7.0 kHz in cohort2 (all P > 0.999 Bonferroni corrected except for left-ear levels at 3.5 and 7.0 kHz with corrected P = 0.138 and P = 0.533).

DATA CONCLUSION: A single 40-minute 3-T MRI with equivalent SPLs of 103.5-113.6 dBA did not result in significant transient disruption of auditory function, as measured by ABR and DPOAE, in neonates with adequate hearing protection.

EVIDENCE LEVEL: 2.

TECHNICAL EFFICACY: Stage 5.

ABSTRACT

OBJECTIVE: It is unclear whether widespread use of biologics is reducing inflammatory bowel disease (IBD) surgical resection rates. We designed a population-based study evaluating the impact of early antitumour necrosis factor (TNF) on surgical resection rates up to 5 years from diagnosis.

DESIGN: We evaluated all patients with IBD diagnosed in Cardiff, Wales 2005-2016. The primary measure was the impact of early (within 1 year of diagnosis) sustained (at least 3 months) anti-TNF compared with no therapy on surgical resection rates. Baseline factors were used to balance groups by propensity scores, with inverse probability of treatment weighting (IPTW) methodology and removing immortal time bias. Crohn’s disease (CD) and ulcerative colitis (UC) with IBD unclassified (IBD-U) (excluding those with proctitis) were analysed.

RESULTS: 1250 patients were studied. For CD, early sustained anti-TNF therapy was associated with a reduced likelihood of resection compared with no treatment (IPTW HR 0.29 (95% CI 0.13 to 0.65), p=0.003). In UC including IBD-U (excluding proctitis), there was an increase in the risk of colectomy for the early sustained anti-TNF group compared with no treatment (IPTW HR 4.6 (95% CI 1.9 to 10), p=0.001).

CONCLUSIONS: Early sustained use of anti-TNF therapy is associated with reduced surgical resection rates in CD, but not in UC where there was a paradoxical increased surgery rate. This was because baseline clinical factors were less predictive of colectomy than anti-TNF usage. These data support the use of early introduction of anti-TNF therapy in CD whereas benefit in UC cannot be assessed by this methodology.

ABSTRACT

BACKGROUND: Background checks are used in nursing education to assess public risk. To date, no study has described the most common and most serious findings in nursing students.

PURPOSE: Our study describes the most common and most serious characteristics of BGC findings in nursing students attending large universities.

METHOD: Our retrospective study describes characteristics of aggregated, de-identified background check data from a convenience sample of 16 US nursing programs set in large universities 2014-2019.

FINDINGS: Sampled programs collected 45,613 background checks, with 1548 findings (3.4 %). Severity of findings included criminal (62.5 %), non-criminal (4.6 %), felony (0.8 %), and other (11.6 %). Severity data were missing from 20.4 % of records. Finding types included substance use (23.7 %), disorderly conduct (8.7 %), property crimes (2.4 %) and crimes against persons (1 %). Type data was missing from 64.3 % of records.

DISCUSSION: Future research should examine whether background check type or severity indicates a nursing student poses a public risk.

ABSTRACT

BACKGROUND: Nursing turnover and shortage are an increasing phenomenon throughout the world; thus, it is critical to determine the factors that contribute to them. Nursing students’ retention plans and turnover intentions are significantly influenced by academic burnout and professional self-concept. The COVID-19 pandemic could aggravate the study-associated stresses leading to burnout and jeopardize the nursing student’s professional socialisation which is a key factor in their professional self-concept formation, it is important to investigate their relationship.

PURPOSE: To examine the relationship between professional self-concept and academic burnout among undergraduate Bachelor of Nursing students and identify predictors related to academic burnout.

METHOD: This cross-sectional study was conducted from May to June 2021. The participants were undergraduate Bachelor of Nursing students from two campuses of a large university in Victoria, Australia. Out of 1630 students, 198 participated in the study. The students were invited to complete an online survey through the university’s online learning platform or flyers. Descriptive statistics, Pearson correlation, and Bootstrapping approaches were used to analyse the data.

RESULTS: The analysis found a significant positive correlation between the nursing students’ total professional self-concept and academic burnout professional efficacy (r = 0.48; p < 0.01). A significant negative correlation was also detected between the total professional self-concept and academic burnout cynicism (r = – 0.21; p < 0.01). Moreover, the total nurse professional self-concept was a significant predictor of both academic burnout subscales cynicism and professional efficacy (p < 0.01).

CONCLUSIONS: Positive nursing professional self-concept may alleviate student’s academic burnout, and it might contribute to the promotion of their professional efficacy.

ABSTRACT

BACKGROUND: The nursing shortage is apparent again after nearly five decades of having a stable workforce. One novel development is that new Registered Nurses (RNs) are exiting their careers too early. Many of them leave the profession for multiple reasons such as burnout and family obligations, yet one reason has emerged – lack of readiness for practice, that also drives the RNs to leave the profession.

PURPOSE: The purpose of this study was twofold – (1) to investigate the relationship between students’ characteristics, their Generalized Self-Efficacy (GSE), Perceived Faculty Support (PFS), the Assessment Technologies, Inc. (ATI) Comprehensive Predictor RN Exam scores and their self-report of readiness for practice and (2) to examine which variables best explains the students’ readiness for practice.

METHODS: A cross-sectional descriptive correlational research design with convenience sampling was utilized. Descriptive statistics were obtained to investigate the students’ socio-demographic data. The Pearson r and multiple regression were used to analyze the relationships and influence between dependent variables Casey-Fink Readiness for Practice scale (CFRPS) and independent variables, students’ characteristics, GSE, PFS, and ATI scores.

RESULTS: One hundred forty-three (143) out of 416 students in five baccalaureate schools from the western region of the United States participated in the survey. Findings showed GSE and PFS had significant positive correlations with students’ readiness for practice. Further, factors of CFRPS in learning strategies, problem-solving, resourcefulness, and team player are best explained by GSE and PFS, accounting for 91 % of the variance.

CONCLUSION: Students’ GSE and PFS can contribute to their readiness for practice. Nurse educators must employ strategies that will bolster students’ preparedness by improving their sense of self-efficacy and showing them the utmost faculty support.
