    Clarifying and expanding equity in assessment by considering three orientations:Fairness, inclusion and justice

    No full text
    Context:Despite increasing discussion and scholarship, equity in assessment is rarelydefined and distinguished in a way that allows for shared understanding in medicaleducation. This paper seeks to clarify and expand the conversation about equity inassessment by critically reviewing three distinct and evolving orientations towardequity in assessment. Orientations refers to the positions, attitudes, interests or pri-orities individuals can hold toward equity in assessment. The three orientationsinclude fairness-oriented assessment, assessment for inclusion and justice-orientedassessment. While fairness-oriented assessment is a prevailing orientation in medicaleducation, assessment for inclusion and justice-oriented assessment, originally devel-oped in other fields of education, deserve careful consideration. Methods:In this paper, the authors explore unique underpinning assumptions ofeach orientation by critically examining the foundational literature of each orienta-tion. They reflect on the unique perspectives each orientation provides, including theactions one might take and what advantages and disadvantages might result fromlooking at equity in assessment from any one orientation. Conclusions:Informed by this reflection, the authors propose that to more effec-tively advance equity in assessment in medical education, those working in the fieldshould clearly identify their respective orientations, intentionally choose methods,tools and measures aligned with their orientations and expand their work by explor-ing alternative orientations

    Background: In patients with colorectal liver metastases (CRLM), preoperative chemotherapy may increase resectability and survival outcomes. However, cytotoxic agents can also cause chemotherapyassociated liver injury (CALI), leading to increased rates of postoperative complications. This study evaluates the association between splenic hypertrophy (SH) after preoperative chemotherapy and postoperative liverspecific complications (LSC), in patients undergoing major liver resection for CRLM. Methods: This retrospective study included patients who underwent major curative liver resection of CRLM following preoperative chemotherapy at the University Hospital RWTH Aachen (UH-RWTH) between 2010-2021. Patients with missing radiological images, incomplete data on chemotherapy regimens, or prior splenectomy were excluded. Volumetric measurements of the spleen were performed on preoperative computerized tomography (CT) and magnetic resonance imaging (MRI) images, using segmentation software (3D-Slicer). Receiver-operating characteristic (ROC) analysis was performed to determine the optimal SH cut-off for predicting postoperative LSC. Independent risk factors of postoperative LSC were examined using logistic regression. Results: A total of 115 patients were included in the study, of which 78 (68%) received oxaliplatin as part of their preoperative chemotherapy regimen. A threshold of 8.6% SH (Youden Index =0.25) was identified as predictive of postoperative LSC. Patients with SH >8.6% (n=62) received oxaliplatin significantly more often (84% vs. 49%; P<0.001) and exhibited higher rates of liver fibrosis (72% vs. 52%, P=0.03) and LSC (63% vs. 38%, P=0.007). Multivariable logistic regression analysis identified SH >8.6% as an independent risk factor Conclusions: Preoperative SH may be a valuable predictor of postoperative LSC in patients undergoing major liver resection for CRLM, following chemotherapy. Further studies are necessary to investigate the impact on a larger cohort and find preventive strategies to mitigate and treat CALI

    Changes in participatory and societal outcomes during the waiting period for cochlear implantation - an observational study

    No full text
    INTRODUCTION: Various factors, including an aging population and expanding eligibility criteria, may increase the demand for cochlear implants (CIs), potentially resulting in longer waiting times. In most Dutch CI centers, the time between referral and surgery exceeds 6 months. Clinical experience suggests that during the waiting period for cochlear implantation, hearing and communication difficulties increase. Simultaneously, there is an interest in outcomes more closely aligned with patient values and needs, which resulted in the SMILE (Societal Merit of Interventions on hearing Loss Evaluation) study. This paper presents results on observed changes in societal and participatory outcomes during waiting time in participants with a time to CI surgery exceeding 6 months. METHODS: SMILE is a prospective multi-center study including 232 individuals who were referred for unilateral CI. Continuous and nominal data from multiple questionnaires, sent immediately after referral and shortly before surgery, were analyzed by computing differences, Cohen's D, and odds ratios. RESULTS: Of the total 232 participants, 102 had a time between inclusion and surgery exceeding 6 months. Of these, 89 had (partially) filled out surveys at both time points. Of all the domain scores 55% did not show differences between timepoints. All Cohen's D estimates were relatively small, ranging from - 0.298 to 0.388 for those outcomes that showed noteworthy changes. CONCLUSION: Waiting time from referral to surgery, even though exceeding 6 months, was observed to not seriously affect non-clinically-prioritized patients in an adverse way. Future investigations should identify subgroups on tolerable waiting times regarding short- and long-term outcomes.

    Risk factors and outcomes of conversions in robotic and laparoscopic liver resections:A nationwide analysis

    No full text
    Background: Unfavorable intraoperative findings or incidents during minimally invasive liver surgery may necessitate conversion to open surgery. This study aimed to identify predictors for conversion in minimally invasive liver surgery and gain insight into outcomes following conversions. Methods: This nationwide, retrospective cohort study compared converted and non-converted minimally invasive liver surgery procedures using data from 20 centers in the Dutch Hepatobiliary Audit (2014–2022). Propensity score matching was applied. Subgroup analyses of converted robotic liver resection versus laparoscopic liver resection and emergency versus non-emergency conversions were performed. Predictors for conversions were identified using backward stepwise multivariable logistic regression. Results: Of 3,530 patients undergoing minimally invasive liver surgery (792 robotic liver resection, 2,738 laparoscopic liver resection), 408 (11.6%) were converted (4.9% robotic liver resection, 13.5% laparoscopic liver resection). Conversion was associated with increased blood loss (580 mL [interquartile range 250–1,200] vs 200 mL [interquartile range 50–500], P &lt; .001), major blood loss (≥500 mL, 58.8% vs 26.7%, P &lt; .001), intensive care admission (19.0% vs 8.4%, P = .005), overall morbidity (38.9% vs 21.0%, P &lt; .001), severe morbidity (17.9% vs 9.6%, P = .002), and a longer hospital stay (6 days [interquartile range 5–8] vs 4 days [interquartile range 2–5], P &lt; .001) but not mortality (2.2% vs 1.2%, P = .387). Emergency conversions had increased intraoperative blood loss (1,500 mL [interquartile range 700–2,800] vs 525 mL [interquartile range 208–1,000], P &lt; .001), major blood loss (87.5% vs 59.3%, P = .005), and intensive care admission (27.9% vs 10.6%, P = .029), compared with non-emergency conversions. Robotic liver resection was linked to lower conversion risk, whereas American Society of Anesthesiologists grade ≥3, larger lesion size, concurrent ablation, technically major, and anatomically major resections were risk factors. Conclusion: Both emergency and non-emergency conversions negatively impact perioperative outcomes in minimally invasive liver surgery. Robotic liver resection reduces conversion risk compared to laparoscopic liver resection.</p

    Clinical and subclinical acute brain injury caused by invasive cardiovascular procedures

    Over the past 50 years, the number and invasiveness of percutaneous cardiovascular procedures globally have increased substantially. However, cardiovascular interventions are inherently associated with a risk of acute brain injury, both periprocedurally and postprocedurally, which impairs medical outcomes and increases health-care costs. Current international clinical guidelines generally do not cover the area of acute brain injury related to cardiovascular invasive procedures. In this international Consensus Statement, we compile the available knowledge (including data on prevalence, pathophysiology, risk factors, clinical presentation and management) to formulate consensus recommendations on the prevention, diagnosis and treatment of acute brain injury caused by cardiovascular interventions. We also identify knowledge gaps and possible future directions in clinical research into acute brain injury related to cardiovascular interventions

    How perceived coercion polarizes unvaccinated people:The mediating role of conspiracy beliefs

    No full text
    During the COVID-19 pandemic, different policies were implemented to increase vaccination uptake. Meanwhile, conspiracy theories spread widely, and vaccinated versus unvaccinated people increasingly polarized against each other. This study examined the associations between perceived vaccination coercion, conspiracy beliefs and polarization. We tested the relationship of vaccination status with perceived vaccination coercion, conspiracy beliefs, and polarization, with a total sample size of N = 1202 (n = 400 in China, n = 401 in the US, and n = 401 in the UK), among them n = 603 were vaccinated and n = 599 were unvaccinated. As pre-registered, unvaccinated people perceived more vaccination coercion and endorsed more conspiracy theories. Conspiracy mentality was positively related to perceived coercion. Contrary to our hypotheses, vaccinated people were more polarized toward unvaccinated people than vice versa. Finally, conspiracy beliefs mediated the link between perceived coercion and polarization among unvaccinated people

    The BMP7-Derived Peptide p[63-82] Reduces Cartilage Degeneration in the Rat ACLT-pMMx Model for Posttraumatic Osteoarthritis

    Objective: Osteoarthritis (OA) is characterized by articular cartilage erosion, pathological subchondral bone changes, and signs of synovial inflammation and pain. We previously identified p[63-82], a bone morphogenetic protein 7 (BMP7)-derived bioactive peptide that attenuates structural cartilage degeneration in the rat medial meniscal tear-model for posttraumatic OA. This study aimed to evaluate the cartilage erosion-attenuating activity of p[63-82] in a different preclinical model for OA (anterior cruciate ligament transection—partial medial meniscectomy [anterior cruciate ligament transection (ACLT)-pMMx]). The disease-modifying action of the p[63-82] was followed-up in this model for 5 and 10 weeks. Design: Skeletally mature male Lewis rats underwent ACLT-pMMx surgery. Rats received weekly intra-articular injections with either saline or 500 ng p[63-82]. Five and 10 weeks postsurgery, rats were sacrificed, and subchondral bone characteristics were determined using microcomputed tomography (µCT). Histopathological evaluation of cartilage degradation and Osteoarthritis Research Society International (OARSI)-scoring was performed following Safranin-O/Fast Green staining. Pain-related behavior was measured by incapacitance testing and footprint analysis. Results: Histopathological evaluation at 5 and 10 weeks postsurgery showed reduced cartilage degeneration and a significantly reduced OARSI score, whereas no significant changes in subchondral bone characteristics were found in the p[63-82]-treated rats compared to the saline-treated rats. ACLT-pMMx-induced imbalance of static weightbearing capacity in the p[63-82] group was significantly improved compared to the saline-treated rats at weeks 5 postsurgery. Footprint analysis scores in the p[63-82]-treated rats demonstrated improvement at week 10 postsurgery. Conclusions: Weekly intra-articular injections of p[63-82] in the rat ACLT-pMMx posttraumatic OA model resulted in reduced degenerative cartilage changes and induced functional improvement in static weightbearing capacity during follow-up.</p

    Education Shapes Future Legal Practitioners' Evaluation of Legal Cases

    No full text
    People oftentimes have misconceptions related to different legal psychological phenomena. These misconceptions can be potentially deleterious when they influence legal decisions. We examined whether these beliefs can be corrected with education. In Study 1, participants provided their agreement for statements related to four case vignettes about different kinds of psychology and law phenomena. Participants were also asked to write the reasons why they provided such an evaluation. In Study 2, we added one additional case vignette. Students improved their beliefs and knowledge concerning the majority of the investigated legal psychological topics after attending the course, except for the evaluation of recidivism risk. Our findings encourage the introduction of courses in legal psychology for students who will become legal practitioners

    Evaluation of Short- and Long-Term Outcomes After Resection in Patients with Locally Advanced versus (Borderline) Resectable Pancreatic Cancer

    No full text
    Objective: To evaluate short and long-term outcomes after pancreatectomy in patients with locally advanced pancreatic cancer (LAPC) compared with patients with (borderline) resectable pancreatic cancer [(B)RPC]. Background: Selected patients diagnosed with LAPC are increasingly undergoing resection after induction chemotherapy. To evaluate the benefit of this treatment approach, it is helpful to compare outcomes in resected patients with primary LAPC to outcomes in resected patients with primary (B)RPC. Methods: Two prospectively maintained nationwide databases were used for this study. Patients with (B)RPC undergoing upfront tumor resection and patients with resected LAPC after induction therapy were included. Outcomes were postoperative pancreas-specific complications, 90-day mortality, pathologic outcomes, disease-free interval, and overall survival. Results: Overall, 879 patients were included; 103 with LAPC (12%) and 776 with (B)RPC (88%). Patients with LAPC had a lower World Health Organization performance score and ageadjusted Charlson Comorbidity Index. Postoperative pancreas-specific complications were comparable between groups, except delayed gastric emptying grade C, which occurred more often in patients with LAPC (9% vs 3%, P = 0.03). Ninety-day mortality was comparable. About half of the patients in both groups [54% in LAPC vs 48% in (B)RPC, P = 0.21] had a radical resection (R0). Disease-free interval was 13 months in both groups (P = 0.12) and overall survival from the date of diagnosis was 24 months in patients with LAPC and 19 months in patients with (B)RPC (P = 0.34). Conclusions: In our nationwide prospective databases, pancreas-specific complications, mortality, and survival in patients with LAPC after pancreatectomy are comparable with those undergoing resection for (B)RPC. These outcomes suggest that postoperative morbidity and mortality after tumor resection in carefully selected patients with LAPC are acceptable.</p

    How to (mis)align participatory approaches with the everyday life? Construction of an improved cookstove in India

    No full text
    Improved cookstoves aimed at reducing exposure to indoor air pollution have had a lasting presence in development and health discussions. Through this article we contribute to current debates in the field by reflecting on our experiences during a cookstove participatory project in two 'non-notified' communities, or 'slums,' in Bangalore, India. We interrogate the alignment between some of the central tenets and methods of participation and the lived experiences of participating communities. The current predominant recommendations focus on developing and implementing cookstoves tailored for user needs. Yet, the project implementation entered a space of uncertainty where the priorities and needs of participants were diverse and changing. While urban infrastructures related to housing and work security, drainage systems, access to health care, and aspects of governance, citizenship and rights, may seem to fall outside the scope of ICS projects, our experiences show how inescapably they shape participatory processes and technologies. We highlight the need to take a closer look at how we can include these broader and changing priorities and needs in our methodologies and reflect on how we can better respond and align them with the ways in which people live
