RESUMO
BACKGROUND: Preoperative geriatric-specific variables (GSV) influence short-term morbidity in surgical patients, but their impact on long-term survival in elderly patients with cancer remains undefined. STUDY DESIGN: This observational cohort study included patients ≥65 years who underwent hepatopancreatobiliary or colorectal operations for malignancy between 2014 and 2020. Individual patient data included merged ACS NSQIP data, Procedure Targeted, and Geriatric Surgery Research variables. Patients were stratified by age: 65-74, 75-84, and ≥85 and presence of these GSVs: mobility aid, preoperative falls, surrogate signed consent, and living alone. Bivariable and multivariable analyses were used to evaluate 1-year mortality and postoperative discharge to facility. RESULTS: 577 patients were included: 62.6 % were 65-74 years old, 31.7 % 75-84, and 5.7 % ≥ 85. 96 patients were discharged to a facility with frequency increasing with age group (11.4 % vs 22.4 % vs 42.4 %, respectively, p < 0.001). 73 patients (12.7 %) died during 1-year follow-up, 32.9 % from cancer recurrence. One-year mortality was associated with undergoing hepatopancreatobiliary operations (p = 0.017), discharge to a facility (p = 0.047), and a surrogate signing consent (p = 0.035). Increasing age (p < 0.001), hepatopancreatobiliary resection (p = 0.002), living home alone (p < 0.001), and mobility aid use (p < 0.001) were associated with discharge to a facility. CONCLUSION: Geriatric-specific variables, living alone and use of a mobility aid, were associated with discharge to a facility. A surrogate signing consent and discharge to a facility were associated with 1-year mortality. These findings underscore the importance of preoperative patient selection and optimization, efficacious discharge planning, and informed decision-making in the care of elderly cancer patients.
RESUMO
Previous work has reported that the extent to which participants dehumanized criminals by denying them uniquely human character traits such as refinement, rationality and morality predicted the severity of the punishment endorsed for them. We revisit this influential finding across six highly powered and pre-registered studies. First, we conceptually replicate the effect reported in previous work, demonstrating that our method is sensitive to detecting relationships between trait-based dehumanization and punishment should they occur. We then investigate whether the apparent relationship between trait-based dehumanization and punishment is driven by the desirability of the traits incorporated into the stimulus set, their perceived humanness, or both. To do this, we asked participants to rate the extent to which criminals possessed uniquely human traits that were either socially desirable (e.g. cultured and civilized) or socially undesirable (e.g. arrogant and bitter). Correlational and experimental evidence converge on the conclusion that apparent evidence for the relationship between trait-based dehumanization and punishment is better explained by the extent to which participants attribute socially desirable attributes to criminals rather than the extent to which they attribute uniquely human attributes. These studies cast doubt on the hypothesized causal relationship between trait-based dehumanization and harm, at least in this context.
RESUMO
Strain-transcending antibodies against virulence-associated subsets of P. falciparum-infected erythrocyte surface antigens could protect children from severe malaria. However, the evidence supporting the existence of such antibodies is incomplete and inconsistent. One subset of surface antigens associated with severe malaria, rosette-mediating Plasmodium falciparum Erythrocyte Membrane Protein one (PfEMP1) variants, cause infected erythrocytes to bind to uninfected erythrocytes to form clusters of cells (rosettes) that contribute to microvascular obstruction and pathology. Here, we tested plasma from 80 individuals living in malaria-endemic regions for IgG recognition of the surface of four P. falciparum rosetting strains using flow cytometry. Broadly reactive plasma samples were then used in antibody elution experiments in which intact IgG was eluted from the surface of infected erythrocytes and transferred to heterologous rosetting strains to look for strain-transcending antibodies. We found that seroprevalence (percentage of positive plasma samples) against allopatric rosetting strains was high in adults (63%-93%) but lower in children (13%-48%). Strain-transcending antibodies were present in nine out of eleven eluted antibody experiments, with six of these recognizing multiple heterologous rosetting parasite strains. One eluate had rosette-disrupting activity against heterologous strains, suggesting PfEMP1 as the likely target of the strain-transcending antibodies. Naturally acquired strain-transcending antibodies to rosetting P. falciparum strains in humans have not been directly demonstrated previously. Their existence suggests that such antibodies could play a role in clinical protection and raises the possibility that conserved epitopes recognized by strain-transcending antibodies could be targeted therapeutically by monoclonal antibodies or vaccines.

OBJECTIVES: Monitoring resident trainees' patient outcomes is essential to improving surgical performance; however, resident-specific follow-up is rarely provided in the current surgical training environment. Whether there is a correlation between individual resident's surgical performance and patients' clinical outcomes remains undefined. In this study, we aimed to use risk-adjusted patient outcomes as an educational tool to track individual surgical trainee performance. STUDY DESIGN: American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) appendectomy and partial colectomy operations (2013-2021) were examined. Residents performing ≥25 operations were included. The primary outcome was ACS NSQIP-defined morbidity adjusted using estimated probability of morbidity. Observed-to-expected ratios (O/E) of morbidity measured overall performance and risk-adjusted cumulative sum (RA-CUSUM) methodology represented surgical resident's performance over time. SETTING: Academic quaternary care institution. PARTICIPANTS: Highest-ranking surgical resident participating in an operation and included in Quality In-Training Initiative. RESULTS: A total of 449 operations were examined. 12 residents performed 343 appendectomy operations. 7 residents (29.3 ± 5.1 operations each) did not have any postoperative morbidity and demonstrated better-than-expected patient outcomes. Three residents did not have morbidity after their seventh/eleventh/fifteenth appendectomies. Two residents (case volume 29, 33) had an O/E ratio > 3. Partial colectomy (nâ¯=â¯106) performed by 4 residents had 2 residents (case volume 30, 26) with better-than-expected outcomes and 2 with worse-than-expected (case volume 25, 25). CONCLUSION: Longitudinal monitoring of postoperative patient outcomes provides an opportunity for trainee self-reflection and system examination. RA-CUSUM methodology offers sequential monitoring allowing for early evaluation and intervention when RA-CUSUM results for a trainee demonstrate higher-than-expected morbidity.

BACKGROUND: There has been tremendous effort to improve quality following colorectal surgery, including the proliferation of minimally invasive techniques, enhanced recovery protocols, and surgical site infection prevention bundles. While these programs have demonstrated improved postoperative outcomes at the institutional level, it is unclear whether similar benefits are present on a national scale. METHODS: American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Targeted Colectomy data from 2012 to 2020 were used to identify patients undergoing minimally invasive surgery (MIS) or open partial colectomy (CPT 44140, 44204) or low anterior resection (CPT 44145, 44207). Chronological cohorts as well as annual trends in 30-day postoperative outcomes including surgical site infection, venous thromboembolism, and length of stay were assessed using both univariable and multivariable regression analyses. RESULTS: 261,301 patients, 135,876 (52 â%) female, with a median age of 62 (IQR 53-72) were included. Across all years, MIS partial colectomy was the most common procedure (37 â%), followed by MIS low anterior resection (27 â%), open partial colectomy (24 â%), and open low anterior resection (12 â%). MIS increased from 59 â% in 2012-2014 to 66 â% in 2018-2020 (p â< â0.001). During this same period, postoperative length of stay decreased from a median of 5 days (IQR 4-7) in 2012-2014 to 4 days (IQR 3-6) in 2018-2020 (p â< â0.001). Superficial surgical site infections decreased from 5.5 â% in 2012-2014 to 2.9 â% in 2018-2020 (p â< â0.001). Deep surgical site infections similarly decreased from 1.1 â% to 0.4 â% between these periods (p â< â0.001). Pulmonary embolism also decreased from 0.6 â% to 0.5 â% between periods (p â= â0.02). 30-day mortality was unchanged at 1.7 â% between 2012-2014 and 2018-2020 (p â= â0.40). After adjustment for ACS NSQIP estimated probability of morbidity and mortality, undergoing a colectomy in 2020 compared to 2012 was associated with a 14 â% decrease in postoperative length of stay (p â< â0.001). CONCLUSIONS: Between 2012 and 2020, significant improvements in postoperative outcomes after colectomy were observed in the United States. These results support the positive impact that the widespread adoption of quality improvement initiatives is having on colorectal patient care nationally.
RESUMO
BACKGROUND: Failure to rescue (FTR) is a quality metric defined as mortality after potentially preventable complications after surgery. Predicting patients who are at the highest risk of mortality after a complication may aid in preventing deaths. Thirty-day follow-up period inadequately captures postoperative deaths; alternatively, a 90-day follow-up period has been advocated. This study aimed to examine the association of a validated frailty metric, the risk analysis index (RAI), with 90-day FTR (FTR-90). METHODS: Patients aged ≥65 years who underwent a major abdominal operation between 2014 and 2020 at a quaternary care center were abstracted. Institutional data were merged with the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) and Geriatric Surgery Research File variables. The association between RAI and FTR-90 was evaluated using multivariable logistic regression. RESULTS: A total of 398 patients with postoperative complications were included. Fifty-two patients (13.1%) died during the 90-day follow-up. The FTR-90 group was older (median age: 76 vs 73 years, respectively; P = .002), had a greater preoperative American Society of Anesthesiologists classification score (P < .001), and had a higher ACS NSQIP estimated risk of morbidity (0.33% vs 0.20%, P < .001) and mortality (0.067% vs 0.012%, P < .001). The FTR-90 group had a greater median RAI score (23 vs 19; P = .002). The RAI score was independently associated with FTR-90 (odds ratio, 1.04; 95% CI, 1.0042-1.0770; P = .028) but not with FTR-30 (P = .13). CONCLUSION: Preoperative frailty, as defined by RAI, is independently associated with FTR at 90-day follow-up. FTR-90 captured nearly 60% more deaths than did FTR-30. Frailty has major implications beyond the typical 30-day follow-up period, and a longer follow-up period must be considered.

BACKGROUND: The risk of venous thromboembolism (VTE) after hepatopancreatobiliary (HPB) surgery is high. Extended postdischarge prophylaxis in this patient population has been controversial. This study aimed to examine the safety of postdischarge extended VTE prophylaxis in patients at high risk of VTE events after HPB surgery. METHODS: Adult patients risk stratified as very high risk of VTE who underwent HPB operations between 2014 and 2020 at a quaternary care center were included. Patients were matched 1:2 extended VTE prophylaxis to the control group (patients who did not receive extended prophylaxis). Analyses compared the proportions of adverse bleeding events between groups. RESULTS: A total of 307 patients were included: 103 in the extended prophylaxis group and 204 in the matched control group. Demographics were similar between groups. More patients in the extended VTE prophylaxis group had a history of VTE (9% vs 3%; P = .045). There was no difference in bleeding events between the extended VTE prophylaxis and the control group (6% vs 2%; P = .091). Of the 6 patients with bleeding events in the VTE prophylaxis group, 5 had gastrointestinal (GI) bleeding, and 1 had hemarthrosis. Of the 4 patients with bleeding events in the control group, 1 had intra-abdominal bleeding, 2 had GI bleeding, and 1 had intra-abdominal and GI bleeding. CONCLUSION: Patients discharged with extended VTE prophylaxis after HPB surgery did not experience more adverse bleeding events compared with a matched control group. Routine postdischarge extended VTE prophylaxis is safe in patients at high risk of postoperative VTE after HPB surgery.

Spinal cord injury results in significant sensorimotor deficits, currently, there is no curative treatment for the symptoms induced by spinal cord injury. Basic and pre-clinical research on spinal cord injury relies on the development and characterization of appropriate animal models. These models should replicate the symptoms observed in human, allowing for the exploration of functional deficits and investigation into various aspects of physiopathology of spinal cord injury. Non-human primates, due to their close phylogenetic association with humans, share more neuroanatomical, genetic, and physiological similarities with humans than rodents. Therefore, the responses to spinal cord injury in nonhuman primates most likely resemble the responses to traumatism in humans. In this review, we will discuss nonhuman primate models of spinal cord injury, focusing on in vivo assessments, including behavioral tests, magnetic resonance imaging, and electrical activity recordings, as well as ex vivo histological analyses. Additionally, we will present therapeutic strategies developed in non-human primates and discuss the unique specificities of non-human primate models of spinal cord injury.
RESUMO
Introduction: Shotgun metagenomics has previously proven effective in the investigation of foodborne outbreaks by providing rapid and comprehensive insights into the microbial contaminant. However, culture enrichment of the sample has remained a prerequisite, despite the potential impact on pathogen detection resulting from the growth competition. To circumvent the need for culture enrichment, we explored the use of adaptive sampling using various databases for a targeted nanopore sequencing, compared to shotgun metagenomics alone. Methods: The adaptive sampling method was first tested on DNA of mashed potatoes mixed with DNA of a Staphylococcus aureus strain previously associated with a foodborne outbreak. The selective sequencing was used to either deplete the potato sequencing reads or enrich for the pathogen sequencing reads, and compared to a shotgun sequencing. Then, living S. aureus were spiked at 105 CFU into 25 g of mashed potatoes. Three DNA extraction kits were tested, in combination with enrichment using adaptive sampling, following whole genome amplification. After data analysis, the possibility to characterize the contaminant with the different sequencing and extraction methods, without culture enrichment, was assessed. Results: Overall, the adaptive sampling outperformed the shotgun sequencing. While the use of a host removal DNA extraction kit and targeted sequencing using a database of foodborne pathogens allowed rapid detection of the pathogen, the most complete characterization was achieved when using solely a database of S. aureus combined with a conventional DNA extraction kit, enabling accurate placement of the strain on a phylogenetic tree alongside outbreak cases. Discussion: This method shows great potential for strain-level analysis of foodborne outbreaks without the need for culture enrichment, thereby enabling faster investigations and facilitating precise pathogen characterization. The integration of adaptive sampling with metagenomics presents a valuable strategy for more efficient and targeted analysis of microbial communities in foodborne outbreaks, contributing to improved food safety and public health.
RESUMO
BACKGROUND: Human error is impossible to eliminate, particularly in systems as complex as healthcare. The extent to which judgment errors in particular impact surgical patient care or lead to harm is unclear. STUDY DESIGN: The American College of Surgeons NSQIP (2018) procedures from a single institution with 30-day morbidity or mortality were examined. Medical records were reviewed and evaluated for judgment errors. Preoperative variables associated with judgment errors were examined using logistic regression. RESULTS: Of the surgical patients who experienced a morbidity or mortality, 18% (31 of 170) experienced an error in judgment during their hospitalization. Patients with hepatobiliary procedure (odds ratio [OR] 5.4 [95% CI 1.23 to 32.75], p = 0.002), insulin-dependent diabetes (OR 4.8 [95% CI 1.2 to 18.8], p = 0.025), severe COPD (OR 6.0 [95% CI 1.6 to 22.1], p = 0.007), or with infected wounds (OR 8.2 [95% CI 2.6 to 25.8], p < 0.001) were at increased risk for judgment errors. CONCLUSIONS: Specific procedure types and patients with certain preoperative variables had higher risk for judgment errors during their hospitalization. Errors in judgment adversely impacted the outcomes of surgical patients who experienced morbidity or mortality in this cohort. Preventing or mitigating errors and closely monitoring patients after an error in judgment is prudent and may improve surgical safety.

AIM: Intra-articular corticosteroid injections (IACIs) can reduce osteoarthritis-related pain, with differing levels of response across patient groups. This systematic review investigates what is known about the positive and negative predictors of outcomes in patients with osteoarthritis who undergo IACIs. METHODS: We systematically searched the Medline, Embase, and Cochrane databases to May 2023 for studies that evaluated patients undergoing IACIs for osteoarthritis and reported on predictors of outcomes in these patients. RESULTS: Eight studies were included. Two were placebo-controlled trials, six were observational studies. Due to the heterogeneity of outcomes and variables between the studies, it was not possible to pool the results for formal meta-analysis. Higher baseline pain, older age, higher BMI, lower range of movement, higher Kellgren-Lawrence radiographic score, joint effusion, and aspiration were shown to be predictors of a positive response to IACIs in some of the included studies. However, other studies showed no difference in response with these variables, or a negative correlation with response. Sex, smoking, mental health status, hypertension/ischaemic heart disease, diabetes mellitus, duration of symptoms, and socioeconomic status did not demonstrate any correlation with the prediction of positive or negative outcomes after IACIs. CONCLUSION: Several patient features have been identified as positive predictors of outcomes following IACIs. However, this systematic review has identified inconsistent and variable findings across the existing literature. Further research with standardization of IACI administration and outcome measures is required to facilitate further analysis of the reliability and significance of predictive factors for response to IACIs.

Background Colorectal cancer most commonly affects the elderly population. Post-colorectal cancer surveillance aims to reduce cancer incidence and mortality, but its necessity and effectiveness are debated, especially in the elderly population. This study explores the relevance of computer tomography (CT) and colonoscopy surveillance in patients aged 75 and over who have undergone curative resection for colorectal cancer. Methods A retrospective analysis of prospectively collected data was conducted on patients aged 75 and over who had undergone surgical resection of colorectal cancer between November 2014 and August 2021. Data on demographics, treatment, survival, and surveillance were gathered from electronic patient records. The primary outcome was adherence to follow-up colonoscopy and CT-scan surveillance following surgery. Results A total of 417 patients underwent colorectal cancer surgery, with 334 included for analysis. The cohort had an average age of 81 years, with the majority receiving laparoscopic surgery and primary anastomosis. Twelve-month CT surveillance showed normal results in 281 patients (91.8%), while 24-month CT surveillance demonstrated normal findings in 244 patients (88.7%). Only 175 patients (52.4%) had colonoscopy follow-up, with 94 (53.7%) showing normal results, 74 (42.3%) demonstrating benign polyps, and two patients (1.1%) having histologically proven cancer. Reasons for not undergoing colonoscopy included declining invitations (30 patients, 19.1%) and being too frail (45 patients, 28.7%). Conclusion This study reinforces the notion that colonoscopy surveillance for patients over the age of 75 may have limited benefits. In an ageing population, the benefits of surveillance in terms of early detection of recurrence must be balanced against the risks of harm from the procedure, the availability of further management, cost-effectiveness, and patient preferences. An individualised approach should be adopted, potentially with colonoscopy surveillance only recommended in patients of higher risk (extramural venous invasion (EMVI)) and a low frailty score with a life expectancy over 10 years.
RESUMO
INTRODUCTION: Long-term data evaluating clinical outcomes in patients with branch-duct Intraductal papillary mucinous neoplasms (BD-IPMN) without high-risk stigmata (HRS) or worrisome features (WF) remain limited. METHODS: This observational cohort study included all patients diagnosed with BD-IPMN without HRS or WF between 2003 and 2019 who were enrolled in a prospective surveillance program. Time-to-progression analysis was performed using a cumulative incidence function plot and survival analysis was conducted using Kaplan-Meier. RESULTS: The median follow-up time for the 267 patient cohort was 44.5 months (interquartile range [IQR]: 24.1-72.2). Radiographic cyst growth was observed in 123 (46.1%) patients; 65 (24.3%) patients progressed to WF/HRS. Twenty-six (9.7%) patients were selected for resection during surveillance: 21 (80.8%) WF, 4 (15.4%) HRS; 1 (3.9%) transformed to mixed-duct. Of all the patients who underwent resection, 5 (19.2%) had adenocarcinoma, and 1 (3.8%) had carcinoma-in-situ. The probability of any radiographic progression was 21.3% (5-year) and 51.3% (10-year). For the entire cohort, there was 1.1% mortality secondary to pancreatic adenocarcinoma and 8.2% all-cause mortality. The 5-year overall survival rate was 91.5%, and at 10 years, 81.5%. CONCLUSION: Approximately one in four patients with nonworrisome BD-IPMN have progression to WF/HRS stigmata during surveillance. However, the risk of malignant transformation remains low. Surveillance strategy remains prudent in this patient population.

INTRODUCTION: Medicaid expansion's (ME) impact on postoperative outcomes after abdominal surgery remains poorly defined. We aimed to evaluate ME's effect on surgical morbidity, mortality, and readmissions in a state that expanded Medicaid (Virginia) compared to a state that did not (Tennessee) over the same time period. METHODS: Virginia Surgical Quality Collaborative (VSQC) American College of Surgeons National Surgical Quality Improvement Program data for Medicaid, uninsured, and private insurance patients undergoing abdominal procedures before Virginia's ME (3/22/18-12/31/18) were compared with post-ME (1/1/19-12/31/19), as were corresponding non-ME state Tennessee Surgical Quality Collaborative (TSQC) data for the same 2018 and 2019 time periods. Postexpansion odds ratios for 30-d morbidity, 30-d mortality, and 30-d unplanned readmission were estimated using propensity score-adjusted logistic regression models. RESULTS: In Virginia, 4753 abdominal procedures, 2097 pre-ME were compared to 2656 post-ME. In Tennessee, 5956 procedures, 2484 in 2018 were compared to 3472 in 2019. VSQC's proportion of Medicaid population increased following ME (8.9% versus 18.8%, P < 0.001) while uninsured patients decreased (20.4% versus 6.4%, P < 0.001). Post-ME VSQC had fewer 30-d readmissions (12.2% versus 6.0%, P = 0.013). Post-ME VSQC Medicaid patients had significantly lower probability of morbidity (-8.18, 95% confidence interval: -15.52 â¼ -0.84, P = 0.029) and readmission (-6.92, 95% confidence interval: -12.56 â¼ -1.27, P = 0.016) compared to pre-ME. There were no differences in probability of morbidity or readmission in the TSQC Medicaid population between study periods (both P > 0.05); there were no differences in mortality between study periods in VSQC and TSQC patient populations (both P > 0.05). CONCLUSIONS: ME was associated with decreased 30-d morbidity and unplanned readmissions in the VSQC. Data-driven policies accounting for ME benefits should be considered.

BACKGROUND: The impact of undernutrition in dogs with protein-losing enteropathy (PLE) caused by inflammatory enteritis, intestinal lymphangiectasia, or both and which variables are most predictive of outcome are unknown. OBJECTIVES: Develop an undernutrition screening score (USS) for use at the time of diagnosis of PLE in dogs, which is predictive of outcome. ANIMALS: Fifty-seven dogs with PLE prospectively recruited from 3 referral hospitals in the United Kingdom. METHODS: An USS based on the presence and severity of 5 variables: appetite, weight loss, and body, muscle, and coat condition and scored out of 15, with higher scores reflecting worse undernutrition, was calculated at the time of diagnosis. Follow-up information was obtained for at least 6 months. RESULTS: Dogs that failed to achieve clinical remission within 6 months had higher USS at diagnosis compared with dogs that achieved remission (median, 7.5; range, 2-14 and median, 5; range, 0-14, respectively). The USS at diagnosis gave an area under the receiver operating characteristic curve (AUC) of 0.656 for predicting nonclinical remission within 6 months, whereas a score consisting of just epaxial muscle loss and coat condition resulted in a larger AUC of 0.728. CONCLUSIONS AND CLINICAL IMPORTANCE: Of the 5 variables assessed in the USS, a combination of epaxial muscle loss and coat condition was most predictive of not achieving clinical remission within 6 months in dogs with PLE. Additional studies will help determine the effect of changes in USS and the 5 associated variables after diagnosis on outcome variables in these dogs.

In propaganda and hate speech, target groups are often compared to dangerous and disgusting animals. Exposure to these animalistic slurs is thought to increase endorsement of intergroup harm but the mechanism by which this happens remains unclear. Across two pre-registered and highly powered studies, we examined how animalistic language influences the cultural transmission of beliefs about target groups. In line with previous work, we found that describing a novel political group with animalistic slurs increased the extent to which participants endorsed harm towards them. Importantly, reading animalistic slurs did not influence the extent to which participants believed the target group possessed uniquely human qualities. Rather, the animalistic slurs influenced endorsement of harm by making the target group appear more undesirable. These findings offer a novel perspective into the nature of dehumanization and new insights into how hate speech functions.
RESUMO
BACKGROUND: Traditional surgical outcomes are measured retrospectively and intermittently, limiting opportunities for early intervention. OBJECTIVES: The objective of this study was to use risk-adjusted cumulative sum (RA-CUSUM) to track perioperative surgical outcomes for laparoscopic gastric bypass. We hypothesized that RA-CUSUM could identify performance variations between surgeons. SETTING: Two mid-Atlantic quaternary care academic centers. METHODS: Patient-level data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) were abstracted for laparoscopic gastric bypasses performed by 3 surgeons at 2 high-volume centers from 2014 to 2021. Estimated probabilities of serious complications, reoperation, and readmission were derived from the MBSAQIP risk calculator. RA-CUSUM curves were generated to signal observed-to-expected odds ratios (ORs) of 1.5 (poor performance) and .5 (superior performance). Control limits were set based on a false positive rate of 5% (α = .05). RESULTS: We included 1192 patients: Surgeon A = 767, Surgeon B = 188, and Surgeon C = 237. Overall rates of serious complications, 30-day reoperations, and 30-day readmissions were 3.9%, 2.5%, and 5.2% respectively, with expected rates of 4.7%, 2.2%, and 5.8%. RA-CUSUM signaled lower-than-expected (OR < .5) rates of readmission and serious complication in Surgeon A, and higher-than-expected (OR > 1.5) readmission rate in Surgeon C. Surgeon A further demonstrated an early period of higher-than-expected (OR > 1.5) reoperation rate before April 2015, followed by superior performance thereafter (OR < .5). Surgeon B's performance generally reflected expected standards throughout the study period. CONCLUSIONS: RA-CUSUM adjusts for clinical risk factors and identifies performance outliers in real-time. This approach to analyzing surgical outcomes is applicable to quality improvement, root-cause analysis, and surgeon incentivization.

Background and study aims Pancreatoscopy-guided electrohydraulic lithotripsy (EHL) has proven to be an effective first-line therapy in symptomatic chronic pancreatitis (CP) patients with obstructing pancreatic duct (PD) stones 1 . However, long-term outcomes of endoscopic EHL remain unknown. The aim of the present study was to evaluate the long-term treatment effects of EHL as first-line therapy and to compare with those obtained in a historical cohort of patients who underwent extracorporeal shockwave lithotripsy (ESWL) as primary treatment. Patients and methods An observational retrospective single-center long-term follow-up study was performed including 19 consecutive patients who previously underwent endoscopic EHL compared to 18 patients who underwent ESWL followed by endoscopic retrograde pancreatography (ERP). The primary endpoint was long-term treatment success after EHL or ESWL defined as no recurrence of symptomatic intraductal stones confirmed on imaging. Secondary endpoints for the EHL-population included long-term clinical success (i.âe., a similar or lower Izbicki Pain Score or reduction in opiate usage as compared to 6-month follow-up), quality of life (QoL), pancreatic function and hospital re-admission rate. Results In the EHL group, 37â% of the patients developed recurrent symptomatic PD stones versus 61â% in the ESWL group after a median follow-up of 35.0 and 76.5 months. Of the patients with recurrence, 71â% versus 100â% underwent a reintervention. Median time to recurrence was 12.0 versus 13.0 months. Clinical success sustained in 58â% of the EHL patients. QoL was not significantly different compared with 6-month follow-up and baseline. Conclusions Also at long-term follow-up, endoscopic EHL as first-line treatment is moderately effective for symptomatic CP patients with treatment success rates that seems at least equally effective as ESWL.
RESUMO
INTRODUCTION: Chronic pancreatitis (CP) has a negative impact on quality of life (QoL). Because CP is a chronic condition, multiple assessments of QoL are required to obtain a thorough understanding of its impact on patients. Such studies are currently lacking. This study aims to gain insight into the course and predictors of QoL in patients with CP using prospective longitudinal data from a large cohort of patients. METHODS: Post hoc analysis of consecutive patients with definite CP registered in a prospective database between 2011 and 2019 in the Netherlands. Patient and disease characteristics, nutritional status, pain severity, medication usage, pancreatic function, and pancreatic interventions were assessed from medical records and through standard follow-up questionnaires. The physical and mental component summary scales of the Short-Form 36 were used to assess physical and mental QoL at baseline and during follow-up. The course of both physical and mental QoL and their associated factors were longitudinally assessed by using generalized linear mixed models. RESULTS: Overall, 1,165 patients with definite CP were included for this analysis. During 10-year follow-up, generalized linear mixed model analyses revealed improvements in both physical (41.6-45.2, P < 0.001) and mental (45.9-46.6, P = 0.047) QoL. Younger age, current alcohol consumption, employment, no need for dietetic consultation, no steatorrhea, lower Izbicki pain score, and pain coping mechanism were positively associated with physical QoL ( P < 0.05). For mental QoL, a positive correlation was found between employment, nonalcoholic CP, no need for dietetic consultation, no steatorrhea, lower Izbicki pain score, pain coping mechanism, and surgical treatment. No association was observed between disease duration and longitudinal QoL per patient. DISCUSSION: This nationwide study provides insight into the dynamics of physical and mental QoL in patients with CP over time. Important and potentially influenceable factors to improve QoL are nutritional status, exocrine pancreatic function, employment status, and patients' coping strategy.
