RESUMEN
BACKGROUND: Surgical site infection (SSI) is one of the most common sources of morbidity after pancreaticoduodenectomy. Surgical site infections are associated with readmissions, prolonged length of stay, delayed initiation of adjuvant chemotherapy and negative effects on quality of life. Incisional vacuum-assisted closure (iVAC) devices applied on closed incisions may reduce SSI rates. The objective of this retrospective review is to evaluate the impact of iVAC on SSI rate after pancreaticoduodenectomy. METHODS: A cohort of patients undergoing pancreaticoduodenectomy at a single institution who had at least 1 risk factor for SSI and who received an iVAC were compared with a historical cohort of high-risk patients who received conventional dressings after pancreaticoduodenectomy. The primary outcome was incidence of SSI within 30 days, abstracted from chart review. Secondary outcomes were 30-day readmission, 90-day mortality, rate of postoperative pancreatic fistula and rate of delayed gastric emptying. RESULTS: In total, 175 patients were included, of whom 61 received an iVAC. The incidence of SSI was 13% (8 of 61 patients) and 16% (18 of 114 patients) in the iVAC and conventional dressing groups, respectively (odds ratio 0.81, 95% confidence interval 0.33-1.98). Preoperative biliary drainage was the most frequent SSI risk factor. Binary logistic regression using SSI as the outcome demonstrated no significant association with iVAC use when adjusted for SSI risk factors. There were no differences in rates of postoperative pancreatic fistula, delayed gastric emptying or 90-day mortality. CONCLUSION: This report describes the outcomes of the integration of iVAC devices into routine clinical practice at a high-volume institution. Application of this device after pancreaticoduodenectomy for patients at elevated risk of SSI was not associated with a reduction in the rate of SSIs.

Importance: Discussions about goals of care with patients who are seriously ill typically occur infrequently and late in the illness trajectory, are of low quality, and focus narrowly on the patient's resuscitation preferences (ie, code status), risking provision of care that is inconsistent with patients' values. The Serious Illness Care Program (SICP) is a multifaceted communication intervention that builds capacity for clinicians to have earlier, more frequent, and more person-centered conversations. Objective: To explore clinicians' experiences with the SICP 1 year after implementation. Design, Setting, and Participants: This qualitative study was conducted at 2 tertiary care hospitals in Canada. The SICP was implemented at Hamilton General Hospital (Hamilton, Ontario) from March 1, 2017, to January 19, 2018, and at Foothills Medical Centre (Calgary, Alberta) from March 1, 2018, to December 31, 2020. A total of 45 clinicians were invited to participate in the study, and 23 clinicians (51.1%) were enrolled and interviewed. Semistructured interviews of clinicians were conducted between August 2018 and May 2019. Content analysis was used to evaluate information obtained from these interviews between May 2019 and May 2020. Exposures: The SICP includes clinician training, communication tools, and processes for system change. Main Outcomes and Measures: Clinicians' experiences with and perceptions of the SICP. Results: Among 23 clinicians interviewed, 15 (65.2%) were women. The mean (SD) number of years in practice was 14.6 (9.1) at the Hamilton site and 12.0 (6.9) at the Calgary site. Participants included 19 general internists, 3 nurse practitioners, and 1 social worker. The 3 main themes were the ways in which the SICP (1) supported changes in clinician behavior, (2) shifted the focus of goals-of-care conversations beyond discussion of code status, and (3) influenced clinicians personally and professionally. Changes in clinician behavior were supported by having a unit champion, interprofessional engagement, access to copies of the Serious Illness Conversation Guide, and documentation in the electronic medical record. Elements of the program, especially the Serious Illness Conversation Guide, shifted the focus of goals-of-care conversations beyond discussion of code status and influenced clinicians on personal and professional levels. Concerns with the program included finding time to have conversations, building transient relationships, and limiting conversation fluidity. Conclusions and Relevance: In this qualitative study, hospital clinicians described components of the SICP as supporting changes in their behavior and facilitating meaningful patient interactions that shifted the focus of goals-of-care conversations beyond discussion of code status. The perceived benefits of SICP implementation stimulated uptake within the medical units. These findings suggest that the SICP may prompt hospital culture changes in goals-of-care dialogue with patients and the care of hospitalized patients with serious illness.

BACKGROUND AND AIMS: Diabetic patients with no history of cardiac infarction have a prevalence of coronary atherosclerosis and a risk of heart attack equivalent to euglycemic patients who have coronary atherosclerosis and have suffered a prior myocardial infarction. Although several murine models of diabetes have been established, none of these show indications of cardiac events. In an attempt to establish a diabetic mouse model with coronary atherosclerosis and myocardial injury, we have fed hyperglycemic ApoE-/-:Ins2+/Akita mice a western diet to enhance the dyslipidemic phenotype. METHODS: Five-week-old ApoE-/-:Ins2+/Akita mice and ApoE-/- controls were fed a diet, 0.15% cholesterol and 21% anhydrous milk lipids, until 25 weeks of age. Changes in lifespan, clinical and metabolic parameters were evaluated as well as atherosclerosis and heart injury. RESULTS: In comparison to male ApoE-/-, male ApoE-/-:Ins2+/Akita mice presented with chronic hyperglycemia (30.8⯱â¯1.2â¯mM vs. 9.3⯱â¯0.5â¯mM) accompanied by extremely high levels of total plasma cholesterol (49.3⯱â¯6.3â¯mM vs. 30.1⯱â¯1.5â¯mM) and triglycerides (11.6⯱â¯1.7â¯mM vs. 2.36⯱â¯0.18â¯mM). These mice have atherosclerosis at multiple vascular sites, including aortic sinus, ascending and descending aorta, brachiocephalic artery and coronary arteries. In addition, myocardial infarcts and a significant reduction of the lifespan (close to 20% of survival vs. other groups) were observed. Distinctively, both strains of female mice presented a parallel increase in plasma lipids, atherosclerosis, and no effects on mortality. CONCLUSIONS: We have established a diabetic mouse model, the western-diet-fed male ApoE-/-:Ins2+/Akita mouse, with profound cardiovascular disease involving extensive atherosclerosis, coronary artery disease and myocardial infarct resulting in shortened lifespan.
