The use of neoadjuvant therapy (NAT) for pancreatic ductal adenocarcinoma (PDAC) is increasing. While there is an association between NAT and improved post-pancreatectomy complication rates in limited patient populations, the strength of the relationship and its applicability to a broader and modern pancreatectomy cohort remains unclear.

We used the 2014-2018 American College of Surgeons National Surgical Quality Improvement Project to evaluate NAT use for PDAC patients undergoing pancreatectomy. We also used propensity score matching techniques to compare 30-day postoperative outcomes, including clinically relevant postoperative pancreatic fistula (CR-POPF) and delayed gastric emptying (DGE), between patients selected for NAT versus upfront surgery.

Patients receiving NAT were more likely to undergo vascular resections (33% vs. 16%, p < 0.001), have perioperative transfusions (18% vs. 12%, p < 0.001), and undergo longer procedures. Rates of CR-POPF (6%, vs. 10%, p < 0.001), DGE (11% vs. 13%, poduodenectomy. These associations should be considered in discussions of multidisciplinary treatment sequencing for patients with PDAC.Pancreatic cancer is one of the most aggressive gastrointestinal malignancies despite multimodality therapy. In the last several years, genomic studies have revealed that carcinogenesis is driven largely by key driver mutations that can be targeted for oncologic therapy. In addition, advances in cancer immunology have identified receptors and monoclonal antibodies that can be manipulated into harnessing the power of the host's immune system for antitumor treatment. These strategies have generated a paradigm shift in the management of several cancer types, including those in the gastrointestinal tract. However, there are several complicating factors when translating the results to pancreatic cancer, including the dense, fibrotic stroma unique to this disease that may shield the cancer cells from both cytotoxic and immunologic agents. Although the majority of trials have been performed in the metastatic setting, this review will focus on both the historic studies that have defined this field as well as the emerging data arising from ongoing efforts to exploit newly discovered mutations and their druggable targets.Ischemic electrocardiographic (ECG) changes during vasodilator stress testing in the presence of abnormal myocardial perfusion imaging (MPI) are associated with more severe coronary artery disease (CAD). However, significance of ECG changes during vasodilator stress test with normal MPI has been controversial. Here, we discuss two cases of significant ischemic ECG changes with vasodilator stress and normal MPI, whose subsequent workup revealed severe obstructive CAD. We also review the available literature on the occurrence and mechanism of these discrepant findings and propose recommendations for management.Research and policymaking on positive mental health and well-being have increased within the last decade, partly fueled by decreasing levels of well-being in the general population and among at-risk groups. However, measurement of well-being often takes place in the absence of reflection on the underlying theoretical conceptualization of well-being. This disguises the fact that different rating scales of well-being often measure very different phenomena because rating scales are based on different philosophical assumptions, which represent radically different foundational views about the nature of well-being. The aim of this paper is to examine the philosophical foundation of the Satisfaction with Life Scale (SWLS) in order to clarify the underlying normative commitments and the psychometric compromises involved in the translation of theory into practice. SWLS is widely used by psychologists, public health professionals, economists, and is popular in national and international surveys of well-being. This paper introduces the philosophical theory of life satisfaction and explores how three central discussions within life satisfaction theory are reflected in the construction of the SWLS; (1) Whether we should be equally satisfied with our past, present and future, (2) Whether we should be satisfied with all the various domains of our lives, and (3) How to avoid the trap of "false consciousness", i.e. that people fail to recognize the injustice or misfortune of their lives. In the end, life satisfaction theory is contrasted with affective foundational theories of well-being, to explore the magnitude and limits of SWLS as a rating scale based on life satisfaction theory.Ethical review and analysis of health policy may help to ensure policies address the needs of society and align with relevant values and principles. Indeed, researchers and bioethicists have recognized the need for ethical frameworks specifically for public health applications. The objective of this research was to compile structured tools for ethical review of (drafted or existing) health policy and to analyze these tools for their scope and philosophical underpinnings. A systematic search and review of academic and grey literature was conducted to compile existing tools designed for health policy ethics review. The search yielded 13 health policy ethical review tools. Degrasyn molecular weight Qualitative content analysis revealed that all of the tools were influenced by multiple ethical values and that a majority were influenced by more than one ethical theory. The most common values were non-maleficence and beneficence (92.3%). The most common influencing ethical theory was the Principles Approach (92.3%). The structure of the tools demonstrates a heterogeneity of methodology designs to approach policy ethics review. This research offers a unique contribution to the bioethics field that provides a useful resource and understanding of the current ethical review tools for health policy.Studies evaluating robotic guidance in lumbar fusion are limited primarily to evaluation of screw accuracy and perioperative complications. This is the first study to evaluate granular differences in short and long-term complication and revision rate profiles between robotic (RG) fluoroscopic (FG) guidance for minimally invasive short-segment lumbar fusions. A retrospective analysis of a prospective, multi-center database was performed. Complications were subdivided into surgical (further subcategorized into adjacent segment disease, new-onset back pain, radiculopathy, motor-deficit, hardware failure, pseudoarthrosis), wound, and medical complications. Complication and revision rates were compared between RG and FG groups cumulatively at 30, 90 days, and 1 year. 374 RG and 111 FG procedures were performed. RG was associated with an 86.25, 83.20, and 69.42% cumulative reduction in complication rate at 30, 90 days, and 1 year, respectively, compared to FG (p  less then  0.001). At all follow-up points, new-onset radiculopathy and medical complications were most prevalent in both groups.
