RESUMO
BACKGROUND/OBJECTIVES: Pancreatic cystic neoplasms (PCNs) are common, among which 13%-23% are serous cystic neoplasms (SCNs). However, diffuse and multifocal variants of SCNs are extremely rare. The differential diagnosis of SCNs from other PCNs is important as the former entities are benign and do not become invasive. OBJECTIVE: This study analyzes the clinical characteristics of multifocal/diffuse SCN through a systematic review of the literature and a case report. METHODS: A comprehensive literature search was executed in the Ovid MEDLINE, Embase, and Google Scholar databases. The search strategy was designed to capture the concept of multifocal/diffuse SCN cases with sufficient clinical information for detailed analysis. Using the final included articles, we analyzed tumor characteristics, diagnostic modalities used, initial management and indications, and patient outcomes. RESULTS: A review of 262 articles yielded 19 publications with 22 cases that had detailed clinical information. We presented an additional case from our institution database. The systematic review of 23 cases revealed that the diffuse variant is more common than the multifocal variant (15 vs 8 cases, respectively). Patients were managed with surgical intervention, conservative treatment, or conservative treatment followed by surgical intervention. Indications for surgery following conservative management mainly included new onset or worsening of symptoms. Only one case reported significant tumor growth after attempting an observational approach. No articles reported recurrence of SCN after pancreatectomy, and no articles reported mortality related to multifocal/diffuse SCNs. CONCLUSION: Despite their expansive-growing and space-occupying characteristics, multifocal/diffuse SCNs should be treated similarly to their more common unifocal counterpart.

Background: Literature describing the effectiveness of teaching strategies in the clinical setting is limited. This realist synthesis review focuses on understanding the effectiveness of teaching strategies used in the clinical setting.Methods: We searched ten databases for English language publications between 1 January 1970 and 31 May 2017 reporting effective teaching strategies, used in a clinical setting, of non-procedural skills. After screening, we used consensus to determine inclusion and employed a standardised instrument to capture study populations, methodology, and outcomes. We summarised what strategies worked, for whom, and in what settings.Results: The initial search netted 53,642 references after de-duplication; 2037 were retained after title and abstract review. Full text review was done on 82 references, with ultimate inclusion of 25 publications. Three specific teaching strategies demonstrated impact on educational outcomes: the One Minute Preceptor (OMP), SNAPPS, and concept mapping. Most of the literature involves physician trainees in an ambulatory environment. All three have been shown to improve skills in the domains of medical knowledge and clinical reasoning.Discussion/conclusions: Apart from the OMP, SNAPPS, and concept mapping, which target the formation of clinical knowledge and reasoning skills, the literature establishing effective teaching strategies in the clinical setting is sparse.

OBJECTIVES: Barrett's esophagus (BE) is the only identifiable premalignant condition for esophageal adenocarcinoma (EAC). Management of BE with low-grade dysplasia continues to be controversial. We aimed to conduct a systematic review and meta-analysis comparing the risk of progression to high-grade dysplasia or EAC among patients with BE with low-grade dysplasia treated with radiofrequency ablation (RFA) compared with surveillance endoscopy. METHODS: Our search included Medline, Embase, and Cochrane Central, was limited to English language articles, and was last searched on 31 December 2015. Studies were reviewed by title and abstract, and then full text by two independent reviewers. Two independent reviewers extracted data. Differences were resolved by consensus. The primary outcome of interest was the relative risk of disease progression among patients with BE with low-grade dysplasia treated with RFAcompared with surveillance. RESULTS: Our search resulted in 2,029 citations, 19 studies were included in the final analysis, totaling 2,746 patients. Relative risk of disease progression in RFA compared with surveillance was 0.14% (95% confidence interval: 0.04-0.45), P=0.001. This measure was stable when only all studies were included. Absolute risk reduction was 10.9% and the number needed to treat was 9.2. Results were stable over several quality measures, overtime, and when excluding randomized trials. The cumulative rate of progression to high-grade dysplasia/EAC was lower in RFA compared with surveillance (1.7% vs. 12.6%, P<0.001). CONCLUSIONS: Similarly, the incidence rate of progression among patients with surveillance was significantly higher from those treated with RFA (0.022 vs. 0.005, P<0.001). RFA results in a significant reduction risk of disease progression to high-grade dysplasia/EAC among patients with BE with low-grade dysplasia.

OBJECTIVE: Anorexia nervosa portends the highest mortality among psychiatric diseases, despite primarily being a disease of adolescents and younger adults. Although some of this mortality risk is attributable to suicide, many deaths are likely cardiovascular in etiology. Recent studies suggest that adverse myocardial structural changes occur in this condition, which could underlie the increased mortality. Given limited prevalence of severe anorexia there is a paucity of clinical and autopsy data to discern an exact cause of death. METHODS: Given this background we conducted a systematic review of the medical literature to provide a contemporary summary of the pathobiologic sequelae of severe anorexia nervosa on the cardiovascular system. We sought to elucidate the impact of anorexia nervosa in four cardiovascular domains: structural, repolarization/conduction, hemodynamic, and peripheral vascular. RESULTS: A number of cardiac abnormalities associated with anorexia nervosa have been described in the literature, including pericardial and valvular pathology, changes in left ventricular mass and function, conduction abnormalities, bradycardia, hypotension, and dysregulation in peripheral vascular contractility. Despite the prevalent theory that malignant arrhythmias are implicated as a cause of sudden death in this disorder, data to support this causal relationship are lacking. DISCUSSION: It is reasonable to obtain routine electrocardiography and measurements of orthostatic vital signs in patients presenting with anorexia nervosa. Echocardiography is generally not indicated unless prompted by clinical signs of disease. Admission to an inpatient unit with telemetry monitoring is recommended for patients with severe sinus bradycardia or junction rhythm, marked prolongation of the corrected QT interval, or syncope.

CONTEXT: Scientific journals are the primary source for dissemination of research findings, and this process relies on rigorous editorial and peer-review. As part of continuing efforts by the Journal of Pain and Symptom Management (JPSM) to advance equity, diversity, and inclusion, JPSM's leadership requested an external evaluation of their publication decisions. OBJECTIVES: 1) Describe primary author characteristics associated with final decisions to accept or reject manuscripts submitted for publication; 2) Report on whether there are potential publication biases in the JPSM editorial or peer-review processes. METHODS: Data consisted of self-reported primary author demographic characteristics associated with manuscript submissions between June 18, 2020, and December 31, 2022. Characteristics included region of residence, race, gender, and ethnicity. A multiple logistic regression model was used to estimate adjusted odds of rejection for each author characteristic. RESULTS: A total of 1940 submissions were evaluated. Compared to authors residing in North America, authors residing in Asia had six-fold greater odds of rejection, authors residing in Europe had four-fold greater odds of rejection, and authors residing in other regions had two-fold greater odds of rejection. Female authors submitted 1.7 times more papers than males, but there was no difference in acceptance rates of their papers in adjusted analysis. CONCLUSION: In this analysis of publication decisions by the JPSM, there were differences in acceptance rates by region of residence, ethnicity, and race but not by gender. Asian authors and authors residing in regions outside of North America had greater odds of rejection compared to White or North American authors.

BACKGROUND/OBJECTIVES: Due to the rarity of the need for claviculectomy and the subsequent clavicle reconstruction, currently there is no consensus on the reconstructive approach for the clavicle. The clavicle is an essential bony structure that is necessary for optimal upper limb anatomical and physiological functionalities. OBJECTIVE: This study analyzes the reconstructive approach, vascular anastomosis, complications, and long-term outcome of clavicle reconstruction using a free vascularized fibular flap through a systematic review of the literature and a case report from our institution. METHODS: A comprehensive literature search was executed in the Ovid MEDLINE, Embase, and Google Scholar databases. The search strategy was designed to capture the concept of cases that underwent clavicle reconstruction after necessary claviculectomy with sufficient clinical information for detailed analysis. Using the final included articles, we analyzed and summarized the outcomes associated with clavicle reconstruction using free fibular osteocutaneous flap. RESULTS: A review of 179 articles yielded 11 publications with 26 cases that had detailed clinical information. We presented an additional case from our institution database. The systematic review of 27 cases revealed that clavicle nonunion due to various causes accounted for 73.08% of the cases for claviculectomy and the eventual reconstruction with a free fibular flap. The mean follow-up period in this study is 29.54 months with the range of 3 to 120 months. A total of 92.31% of the cases showed evidence of complete osseous consolidation. CONCLUSION: When claviculectomy is necessary, a free fibular flap can be utilized for the subsequent clavicle reconstruction to provide optimal anatomical and physiological functionality of the clavicle.

BACKGROUND: Preventing firearm-involved injuries is a critical public health priority. Firearm locking devices can prevent firearm injuries, such as suicide and unintentional shootings, as well as theft. Various firearm locking devices exist; however, little is known about firearm owners' preferred locking devices for secure firearm storage. In this systematic review, we examined existing literature on preferred locking devices for secure storage of personal firearms among United States (US) firearm owners with the purpose of understanding practical implications and needs for future research. METHODS: We searched 8 major databases, as well as the grey literature, for English-language sources published on or before January 24, 2023, that empirically examined firearm locking device preferences. Following PRISMA guidelines, coders independently screened and reviewed 797 sources using pre-determined criteria. Overall, 38 records met inclusion criteria and were included in this review. RESULTS: The majority of studies measure and report on participant use of various types of locking devices, but few go on to measure preference between device options and the attributes and features that may contribute to an individual's preference. Included studies suggest that a preference for larger devices, such as lockboxes and gun safes, may exist among US firearm owners. CONCLUSIONS: Review of included studies suggests that current prevention efforts may not be aligned with firearm owners' preferences. Additionally, findings from this systematic review emphasize the need for additional methodological rigorous research to understand firearm locking device preferences. Expanded knowledge in this area will result in actionable data and foundational best practices for programming that encourages behavior change concerning secure storage of personal firearms to prevent injury and death.

Introduction: Children with cancer experience symptom distress which has been correlated with decreased quality of life (QOL). Creative arts therapy (CAT) encompasses the therapeutic use of creative arts which may improve QOL among children with cancer by affecting symptoms. Therefore, the research question was asked: Does CAT affect symptoms of pain, nausea, fatigue, anxiety, and mood in children with cancer? Methods: Based on the study question, a comprehensive literature search of PubMed, CINAHL, PsycINFO, and Embase was completed. Inclusion criteria limited articles to specific symptom outcomes in two-group intervention studies in the English language. Selected articles were confirmed for inclusion by the study team, followed by group discussion to develop matrices with levels of evidence based on the Grading of Recommendations Assessment, Development, and Evaluation (Grade) guidelines. Results: Initial searches revealed 1,391 articles, screened to 44 for systematic review. Based on the inclusion criteria, 11 articles remained. Four studies had evidence levels graded as low, three were low to moderate, and four were moderate. Outcomes of mood and anxiety were measured in five studies, pain in four, fatigue in two, and nausea in one study. Discussion: Psychological outcomes were measured more commonly than physical outcomes. Evidence reached a moderate grade in four studies. Summary: Through this synthesis of intervention studies with CAT in children with cancer, improvement in distressing symptoms has potential, but the state of the science for symptom management with CAT could be strengthened for nurses to promote CAT to improve QOL among children with cancer.

INTRODUCTION: Clinicians that care for hospitalised patients face unprecedented work conditions with exposure to highly infectious disease, exceedingly high patient numbers, and unpredictable work demands, all of which have resulted in increases in stress and burnout. Preliminary studies suggest that increasing workloads negatively affect inpatient clinician well-being and may negatively affect job performance; yet high workloads may be prioritised secondary to financial drivers or from workforce shortages. Despite this, the correlation between workload and these negative outcomes has not been fully quantified. Additionally, there are no clear measures for inpatient clinician workload and no standards to define ideal workloads. Using the protocol described here, we will perform a scoping review of the literature to generate a comprehensive understanding of how clinician workload of medical patients is currently defined, measured in clinical settings and its impact on the workforce, patients and institutional outcomes. METHODS AND ANALYSIS: We will follow the methodology outlined by Joanna Briggs Institute and Arksey and O'Malley to conduct a comprehensive search of major electronic databases including Ovid Medline (PubMed), Embase (Embase.com), PsycINFO, ProQuest Dissertations and Google Scholar. All relevant published peer-reviewed and dissertaion grey literature will be included. Data will be extracted using a standardised form to capture key article information. Results will be presented in a descriptive narrative format. ETHICS AND DISSEMINATION: This review does not require ethics approval though all included studies will be screened to ensure appropriate approval. The synthesis of this literature will provide a better understanding of the current state of work for inpatient clinicians, associated outcomes, and will identify gaps in the literature. These findings will be used in conjunction with an expert Delphi panel to identify measures of inpatient clinician workload to then guide the development of a novel workforce mobile application to actively track clinician work. We aim to lay the groundwork for future workforce studies to understand the optimal workloads that drive key outcomes for clinicians, patients and institutions.

Postoperative cognitive dysfunction (POCD) has been increasingly recognized as a contributor to postoperative complications. A consensus-working group recommended that POCD should be distinguished between delayed cognitive recovery, ie, evaluations up to 30 days postoperative, and neurocognitive disorder, ie, assessments performed between 30 days and 12 months after surgery. Additionally, the choice of the anesthetic, either inhalational or total intravenous anesthesia (TIVA) and its effect on the incidence of POCD, has become a focus of research. Our primary objective was to search the literature and conduct a meta-analysis to verify whether the choice of general anesthesia may impact the incidence of POCD in the first 30 days postoperatively. As a secondary objective, a systematic review of the literature was conducted to estimate the effects of the anesthetic on POCD between 30 days and 12 months postoperative. For the primary objective, an initial review of 1913 articles yielded ten studies with a total of 3390 individuals. For the secondary objective, four studies with a total of 480 patients were selected. In the first 30 days postoperative, the odds-ratio for POCD in TIVA group was 0.46 (95% CI = 0.26-0.81; p = 0.01), compared to the inhalational group. TIVA was associated with a lower incidence of POCD in the first 30 days postoperatively. Regarding the secondary objective, due to the small number of selected articles and its high heterogeneity, a metanalysis was not conducted. Given the heterogeneity of criteria for POCD, future prospective studies with more robust designs should be performed to fully address this question.
RESUMO
Intraductal papillary mucinous neoplasms (IPMN) are common but difficult to manage since accurate tools for diagnosing malignancy are unavailable. This study tests the diagnostic value of the main pancreatic duct (MPD) diameter for detecting IPMN malignancy using a meta-analysis of published data of resected IPMNs. Collected from a comprehensive literature search, the articles included in this analysis must report malignancy cases (high-grade dysplasia (HGD) and invasive carcinoma (IC)) and MPD diameter so that two MPD cut-offs could be created. The sensitivity, specificity, and odds ratios of the two cutoffs for predicting malignancy were calculated. A review of 1493 articles yielded 20 retrospective studies with 3982 resected cases. A cutoff of ≥5 mm is more sensitive than the ≥10 mm cutoff and has pooled sensitivity of 72.20% and 75.60% for classification of HGD and IC, respectively. Both MPD cutoffs of ≥5 mm and ≥10 mm were associated with malignancy (OR = 4.36 (95% CI: 2.82, 6.75) vs. OR = 3.18 (95% CI: 2.25, 4.49), respectively). The odds of HGD and IC for patients with MPD ≥5 mm were 5.66 (95% CI: 3.02, 10.62) and 7.40 (95% CI: 4.95, 11.06), respectively. OR of HGD and IC for MPD ≥10 mm cutoff were 4.36 (95% CI: 3.20, 5.93) and 4.75 (95% CI: 2.39, 9.45), respectively. IPMN with MPD of >5 mm could very likely be malignant. In selected IPMN patients, pancreatectomy should be considered when MPD is >5 mm.
RESUMO
BACKGROUND: Military personnel and Veterans are at increased risk for suicide. Theoretical and conceptual arguments have suggested that elevated levels of acquired capability (AC) could be an explanatory factor accounting for this increased risk. However, empirical research utilizing the Acquired Capability for Suicide Scale (ACSS) in military populations has yielded mixed findings. METHODS: To better ascertain what factors are associated with AC, and whether methodological limitations may be contributing to mixed findings, a systematic review was conducted. RESULTS: A total of 31 articles utilized the ACSS to examine factors associated with AC, including combat history, in United States (U.S.) military personnel and Veterans. Nearly all studies (96.8%) were rated high risk of bias. Use of the ACSS varied, with seven different iterations utilized. Nearly all studies examined correlations between the ACSS and sample characteristics, mental health and clinical factors, Interpersonal Theory of Suicide constructs, and/or suicide-specific variables. Results of higher-level analyses, dominated by cross-sectional designs, often contradicted correlational findings, with inconsistent findings across studies. LIMITATIONS: Included studies were non-representative of all U.S. military and Veteran populations and may only generalize to these populations. CONCLUSIONS: Due to the high risk of bias, inconsistent use of the ACSS, lack of sample heterogeneity, and variability in factors examined, interpretation of current ACSS empirical data is cautioned. Suggestions for future research, contextualized by these limitations, are discussed.

Caregivers of patients often provide key support for patients after hospitalization. This qualitative metasynthesis describes caregiver perspectives about care coordination for patients discharged from the hospital. A literature search of Ovid Medline and CINAHL completed on May 23, 2018, identified 1,546 studies. Twelve articles were included in the final metasynthesis. Caregiver perspectives about care coordination were compiled into overall themes. A subanalysis of studies in which patients were discharged with home health services was completed. Five main themes emerged related to caregiver perspectives on care coordination after hospitalization: (a) Suboptimal access to clinicians after discharge, (b) Feeling disregarded by clinicians, (c) Need for information and training at discharge, (d) Overwhelming responsibilities to manage appointments and medications, and (e) Need for emotional support.Findings from this metasynthesis suggest the need for clinicians to engage with caregivers to provide support, training, and communication after hospital discharge.

BACKGROUND: Informed consent is an ethical imperative of surgical practice. This requires effective communication of procedural risks to patients and is learned during residency. No systematic review has yet examined current risk disclosure. This systematic review aims to use existing published information to assess preoperative provision of risk information by surgeons. METHODS: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses as a guide, a standardized search in Ovid MEDLINE, Embase, CINHAL, and PubMed was performed. Three reviewers performed the study screening, with 2-reviewer consensus required at each stage. Studies containing objective information concerning preoperative risk provision in adult surgical patients were selected for inclusion. Studies exclusively addressing interventions for pediatric patients or trauma were excluded, as were studies addressing risks of anesthesia. RESULTS: The initial search returned 12,988 papers after deduplication, 33 of which met inclusion criteria. These studies primarily evaluated consent through surveys of providers, record reviews and consent recordings. The most ubiquitous finding of all study types was high levels of intra-surgeon variation in what risk information is provided to patients preoperatively. Studies recording consents found the lowest rates of risk disclosure. Studies using multiple forms of investigation corroborated this, finding disparity between verbally provided information vs chart documentation. CONCLUSIONS: The wide variance in what information is provided to patients preoperatively inhibits the realization of the ethical and practical components of informed consent. The findings of this review indicate that significant opportunities exist for practice improvement. Future development of surgical communication tools and techniques should emphasize standardizing what risks are shared with patients.

BACKGROUND: Fecal microbiota transplantation (FMT) restores a diverse bacterial profile to the gastrointestinal tract and may effectively treat patients with Clostridium difficile infection (CDI). The objective of this systematic review was to evaluate the effectiveness of FMT in the treatment of CDI. METHODS: Ovid MEDLINE, EMBASE, Web of Science, and Cochrane database were used. The authors searched studies with 10 or more patients examining the resolution of symptoms after FMT in patients with CDI. Reviews, letters to the editors, and abstracts were excluded. Participants were patients with CDI. Intervention used was FMT. Quality assessment was performed using the Cochrane risk of bias assessment tool. Results were synthesized using a narrative approach. RESULTS: Retrospective and uncontrolled prospective cohort studies suggest that FMT is a highly effective therapy for recurrent/refractory CDI, with clinical success rates ranging from 83% to 100%, which is similar to rates published by two randomized controlled trials. Fecal microbiota transplantation may be effectively administered via antegrade (upper gastrointestinal) or retrograde (lower gastrointestinal) routes of delivery. Fecal microbiota transplantation rarely results in major adverse events. However, diarrhea, cramping, and bloating commonly occur and are typically self-limited. Most studies were uncontrolled retrospective studies. CONCLUSION: Fecal microbiota transplantation should be considered in patients with recurrent episodes of mild to moderate CDI who have failed conventional antimicrobial therapy. There is insufficient evidence to recommend FMT for the treatment of severe CDI. LEVEL OF EVIDENCE: Systematic review, level III.
