RESUMO
BACKGROUND: The best approaches to supplemental oxygen administration during surgery remain unclear, which may contribute to variation in practice. This study aimed to assess determinants of oxygen administration and its variability during surgery. METHODS: Using multivariable linear mixed-effects regression, the study measured the associations between intraoperative fraction of inspired oxygen and patient, procedure, medical center, anesthesiologist, and in-room anesthesia provider factors in surgical cases of 120 min or longer in adult patients who received general anesthesia with tracheal intubation and were admitted to the hospital after surgery between January 2016 and January 2019 at 42 medical centers across the United States participating in the Multicenter Perioperative Outcomes Group data registry. RESULTS: The sample included 367,841 cases (median [25th, 75th] age, 59 [47, 69] yr; 51.1% women; 26.1% treated with nitrous oxide) managed by 3,836 anesthesiologists and 15,381 in-room anesthesia providers. Median (25th, 75th) fraction of inspired oxygen was 0.55 (0.48, 0.61), with 6.9% of cases less than 0.40 and 8.7% greater than 0.90. Numerous patient and procedure factors were statistically associated with increased inspired oxygen, notably advanced American Society of Anesthesiologists classification, heart disease, emergency surgery, and cardiac surgery, but most factors had little clinical significance (less than 1% inspired oxygen change). Overall, patient factors only explained 3.5% (95% CI, 3.5 to 3.5%) of the variability in oxygen administration, and procedure factors 4.4% (95% CI, 4.2 to 4.6%). Anesthesiologist explained 7.7% (95% CI, 7.2 to 8.2%) of the variability in oxygen administration, in-room anesthesia provider 8.1% (95% CI, 7.8 to 8.4%), medical center 23.3% (95% CI, 22.4 to 24.2%), and 53.0% (95% CI, 52.4 to 53.6%) was unexplained. CONCLUSIONS: Among adults undergoing surgery with anesthesia and tracheal intubation, supplemental oxygen administration was variable and appeared arbitrary. Most patient and procedure factors had statistical but minor clinical associations with oxygen administration. Medical center and anesthesia provider explained significantly more variability in oxygen administration than patient or procedure factors.

Allografts derived from live-birth tissue obtained with donor consent have emerged as an important treatment option for wound and soft tissue repairs. Placental membrane derived from the amniotic sac consists of the amnion and chorion, the latter of which contains the trophoblast layer. For ease of cleaning and processing, these layers are often separated with or without re-lamination and the trophoblast layer is typically discarded, both of which can negatively affect the abundance of native biological factors and make the grafts difficult to handle. Thus, a full-thickness placental membrane that includes a fully-intact decellularized trophoblast layer was developed for homologous clinical use as a protective barrier and scaffold in soft tissue repairs. Here, we demonstrate that this full-thickness placental membrane is effectively decellularized while retaining native extracellular matrix (ECM) scaffold and biological factors, including the full trophoblast layer. Following processing, it is porous, biocompatible, supports cell proliferation in vitro, and retains its biomechanical strength and the ability to pass through a cannula without visible evidence of movement or damage. Finally, it was accepted as a natural scaffold in vivo with evidence of host-cell infiltration, angiogenesis, tissue remodelling, and structural layer retention for up to 10 weeks in a murine subcutaneous implant model.

INTRODUCTION: Crises like the COVID-19 pandemic create blood product shortages. Patients requiring transfusions are placed at risk and institutions may need to judiciously administer blood during massive blood transfusions protocols (MTP). The purpose of this study is to provide data-driven guidance for the modification of MTP when the blood supply is severely limited. METHODS: This is a retrospective cohort study of 47 Level I and II trauma centers (TC) within a single healthcare system whose patients received MTP from 2017 to 2019. All TC used a unifying MTP protocol for balanced blood product transfusions. The primary outcome was mortality as a function of volume of blood transfused and age. Hemoglobin thresholds and measures of futility were also estimated. Risk-adjusted analyses were performed using multivariable and hierarchical regression to account for confounders and hospital variation. RESULTS: Proposed MTP maximum volume thresholds for three age groupings are as follows: 60 units for ages 16-30 y, 48 units for ages 31-55 y, and 24 units for >55 y. The range of mortality under the transfusion threshold was 30%-36% but doubled to 67-77% when the threshold was exceeded. Hemoglobin concentration differences relative to survival were clinically nonsignificant. Prehospital measures of futility were prehospital cardiac arrest and nonreactive pupils. In hospital risk factors of futility were mid-line shift on brain CT and cardiopulmonary arrest. CONCLUSIONS: Establishing MTP threshold practices under blood shortage conditions, such as the COVID pandemic, could sustain blood availability by following relative thresholds for MTP use according to age groups and key risk factors.

Objective: Older adults experience numerous changes in their social networks and social environment that may worsen preexisting posttraumatic stress disorder (PTSD) symptoms. This study tested whether tangible support, appraisal support, belonging support, and self-esteem were associated with trauma symptom burden among community-dwelling older Black and White adults at baseline and over 12 months of follow-up.Methods: This study used data collected from a randomized controlled trial for depression prevention in adults 50 years of age or older who had subsyndromal depression (2006-2011). Two hundred forty-four participants (including 90 older Black adults) were randomly assigned to a problem-solving therapy arm or an active control arm. The Interpersonal Support Evaluation List (ISEL) was administered at baseline and 12 months later. Linear regression analysis was used to examine associations of each of the ISEL dimensions with DSM-IV-defined PTSD symptoms at baseline and over time, with control for well-established correlates of PTSD including depression, anxiety, and sleep quality.Results: Participants were a mean (SD) of 65.6 (11.0) years of age, and 71% percent were female. Belongingness support was the only dimension of interpersonal support significantly associated with PTSD symptoms at baseline (ß = -0.192, t = -3.582, P < .001) and 12 months later (ß = -0.183, t = -2.735, P < .01). Regression models accounted for a large proportion of variance in PTSD symptoms. The association between belongingness support and PTSD symptoms did not vary by participant race.Conclusions: A strong perception of belongingness to family and/or friends was associated with fewer PTSD symptoms at baseline and over 12 months. This observation generates the hypothesis that behavioral interventions which directly target and modify interpersonal support may benefit both older Black and older White adults who have experienced trauma.Trial Registration: ClinicalTrials.gov identifier: NCT00326677.

BACKGROUND: Traumatic brain injury (TBI) is a leading cause of death and disability in older adults. The aim of this study was to characterize the burden of TBI in older adults by describing demographics, care location, diagnoses, outcomes, and payments in this high-risk group. METHODS: Using 2016-2019 Centers for Medicare & Medicaid Services (CMS) Inpatient Standard Analytical Files (IPSAF), patients >65 years with TBI (>1 injury ICD-10 starting with "S06") were selected. Trauma center levels were linked to the IPSAF file via American Hospital Association Hospital Provider ID and fuzzy-string matching. Patient variables were compared across trauma center levels. RESULTS: Three hundred forty-eight thousand eight hundred inpatients (50.4% female; 87.1% white) from 2963 US hospitals were included. Level I/II trauma centers treated 66.9% of patients; non-trauma centers treated 21.5%. Overall inter-facility transfer rate was 19.2%; in Level I/II trauma centers transfers-in represented 23.3% of admissions. Significant TBI (Head AIS ≥3) was present in 70.0%. Most frequent diagnoses were subdural hemorrhage (56.6%) and subarachnoid hemorrhage (30.6%). Neurosurgical operations were performed in 10.9% of patients and operative rates were similar regardless of center level. Total unadjusted mortality for the sample was 13.9%, with a mortality of 8.1% for those who expired in-hospital, and an additional 5.8% for those discharged to hospice. Medicare payments totaled $4.91B, with the majority (73.4%) going to Level I/II trauma centers. CONCLUSIONS: This study fills a gap in TBI research by demonstrating that although the majority of older adult TBI patients in the United States receive care at Level I/II trauma centers, a substantial percentage are managed at other facilities, despite 1 in 10 requiring neurosurgical operation regardless of level of trauma center. This analysis provides preliminary data on the function of regionalized trauma care for older adult TBI care. Future studies assessing the efficacy of early care guidelines in this population are warranted.

BACKGROUND: Few large investigations have addressed the prevalence of COVID-19 infection among trauma patients and impact on providers. The purpose of this study was to quantify the prevalence of COVID-19 infection among trauma patients by timing of diagnosis, assess nosocomial exposure risk, and evaluate the impact of COVID-19 positive status on morbidity and mortality. METHODS: Registry data from adults admitted 4/1/2020-10/31/2020 from 46 level I/II trauma centers were grouped by: timing of first positive status (Day 1, Day 2-6, or Day ≥ 7); overall Positive/Negative status; or Unknown if test results were unavailable. Groups were compared on outcomes (Trauma Quality Improvement Program complications) and mortality using univariate analysis and adjusted logistic regression. RESULTS: There were 28 904 patients (60.7% male, mean age: 56.4, mean injury severity score: 10.5). Of 13 274 (46%) patients with known COVID-19 status, 266 (2%) were Positive Day 1, 119 (1%) Days 2-6, 33 (.2%) Day ≥ 7, and 12 856 (97%) tested Negative. COVID-19 Positive patients had significantly worse outcomes compared to Negative; unadjusted comparisons showed longer hospital length of stay (10.98 vs 7.47;P < .05), higher rates of intensive care unit (57.7% vs 45.7%; P < .05) and ventilation use (22.5% vs 16.9%; P < .05). Adjusted comparisons showed higher rates of acute respiratory distress syndrome (1.7% vs .4%; P < .05) and death (8.1% vs 3.4%; P < .05). CONCLUSIONS: This multicenter study conducted during the early pandemic period revealed few trauma patients tested COVID-19 positive, suggesting relatively low exposure risk to care providers. COVID-19 positive status was associated with significantly higher mortality and specific morbidity. Further analysis is needed with consideration for care guidelines specific to COVID-19 positive trauma patients as the pandemic continues.

Every single human being who has ever been conceived has come into existence precisely because God wants him or her to exist. The present article offers psychological and spiritual considerations to assist people who, in a variety of settings, are evaluating medical-assisted technologies that require the removal of gametes from the body, especially those procedures that involve the buying and selling of gametes. Gamete "donation" is a misnomer when the transactions involve cash payment. Gamete "donation" is contrasted with the "self-donation" that a married couple makes to each other, and by extension to their children, in the marital embrace. The article draws out some of the implications of this contrast, particularly to the child's sense of identity. Particular attention is drawn to the mistakes and mix-ups that can occur when the gametes are removed from the body, which would be literally impossible under the circumstances of natural procreation. I conclude that the perennial teaching of the Catholic Church makes a uniquely humane and personalist contribution to the important public conversation about the use of assisted reproduction.
RESUMO
Background: Bacteremia is a potentially lethal complication. Limited research exists describing its incidence and associated outcomes in trauma patients. This descriptive study characterized the incidence, risk factors, and outcomes of bacteremia in trauma patients. Methods: This study used 2017-2020 system-wide Trauma Registry/Electronic Data Warehouse to select trauma activations aged ≥18 years. Blood culture information, including pathogen genera and species, was obtained from electronic laboratory records. Bacteremia positive was defined as two blood cultures within two hours of each other, growing the same organism; bacteremia negative as no growth, only one blood culture with growth, or growth of two different organisms. Bacteremia-positive and bacteremia-negative patients were compared with patients without blood cultures. Logistic regression compared blood culture results with outcomes, adjusting for age, gender, Injury Severity Score (ISS), and comorbidities. Results: Of 158,884 patients at 89 centers, 17,166 (10.8%) had blood cultures. Of those with blood cultures, 1214 were bacteremia positive (7.1%). Compared with no blood cultures, bacteremia-positive patients were more likely male, with higher ISS, and more comorbidities and intensive care unit use. Bacteremia-positive patients were more likely to die (adjusted odds ratio [aOR], 3.78; 95% confidence interval [CI], 3.17-4.51; p < 0.001) and have severe sepsis/septic shock (aOR, 114.91; 95% CI, 95.09-138.85; p < 0.001). Most common isolates were Staphylococcus epidermidis (14%), non-methicillin resistant Staphylococcus aureus (12%), and Escherichia coli (6%), with highest mortality associated with Pseudomonas aeruginosa (45%), Enterococcus faecalis (30%), and Escherichia coli (28%). Conclusions: Bacteremia in trauma is uncommon (<1%) but associated with increased resource use and poorer outcomes. Bacteremia, or suspicion thereof, identifies a high-risk population and justifies aggressive empiric intervention to maximize survival.

INTRODUCTION: Delirium occurs frequently after lung transplantation and is associated with poor clinical outcomes. Significantly prolonged jugular venous congestion (JVC) occurs during off-pump lung transplantation and is thought to impair cerebral perfusion. Our study aimed to test the hypothesis that increased intraoperative JVC is associated with an increased risk of postoperative delirium among lung transplantation recipients. METHODS: This is a retrospective observational cohort study. Adult patients who received off-pump lung transplantation at the Vanderbilt University Medical Center between 2006 and 2016 are included. The magnitude of JVC was calculated by the area under the curve (AUC) of the central venous pressure (CVP) above the threshold of 12 mmHg. Postoperative delirium was assessed by Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) criteria during their ICU stay. Multivariate regression analysis was used to determine the association of intraoperative JVC with postoperative delirium, adjusting for baseline demographics, surgical, and intraoperative characteristics. RESULTS: Thirty-two (23.5%) out of 136 patients developed delirium in the ICU. There was no statistical difference in terms of intraoperative JVC between patients with delirium and those without (4058 ± 6650 vs. 3495 ± 10 151 mmHg min; p = .772). Furthermore, during multivariate regression analysis, JVC was not associated with an increased risk of delirium (odds ratio: 1.03 per 100 mmHg min increase in venous congestion; 95% confidence interval: .31, 3.39; p = .96). CONCLUSIONS: Delirium occurred frequently after off-pump lung transplantation. Although physiologically plausible, the present study did not find an association between increased JVC during off-pump lung transplantation and an increased risk of postoperative delirium.

BACKGROUND: Only a fraction of pediatric trauma patients are treated in pediatric-specific facilities, leaving the remaining to be seen in centers that must decide to admit the patient to a pediatric or adult unit. Thus, there may be inconsistencies in pediatric trauma admission practices among trauma centers. OBJECTIVE: Describe current practices in admission decision making for pediatric patients. METHODS: An email survey was distributed to members of three professional organizations: The American Association for the Surgery of Trauma, Society of Trauma Nurses, and Pediatric Trauma Society. The survey contained questions regarding pediatric age cutoffs, institutional placement decisions, and scenario-based assessments to determine mitigating placement factors. RESULTS: There were 313 survey responses representing freestanding children's hospitals (114, 36.4%); children's hospitals within general hospitals (107, 34.2%), and adult centers (not a children's hospital; 90, 28.8%). The mean age cutoff for pediatric admission was 16.6 years. The most reported cutoff ages were 18 years (77, 25.6%) and 15 years (76, 25.2%). The most common rationales for the age cutoffs were "institutional experience/tradition" (139, 44.4%) and "physician preference" (89, 28.4%). CONCLUSION: There was no single widely accepted age cutoff that distinguished pediatric from adult trauma patients for admission placement. There was significant variability between and within the types of facilities, with noted ambiguity in the definition of a "pediatric" patient. Thresholds appear to be based primarily on subjective criteria such as traditions or preferences rather than scientific data. Institutions should strive for objective, evidence-based policies for determining the appropriate placement of pediatric patients.

IMPORTANCE: Fatigue is a chronic and distressing sequela of traumatic brain injury (TBI). Little evidence exists for the efficacy of interventions that address post-TBI fatigue. OBJECTIVE: To evaluate the preliminary efficacy of a self-management intervention (Maximizing Energy; MAX) for reducing the impact (primary outcome) and severity of fatigue on daily life, improving fatigue experience, and increasing participation compared with a health education (HE) intervention. DESIGN: Pilot randomized controlled trial (RCT). SETTING: Community. PARTICIPANTS: Forty-one participants randomly assigned to the MAX (n = 20) or HE (n = 21) intervention. INTERVENTIONS: The MAX intervention included problem-solving therapy with energy conservation education to teach participants fatigue management. The HE intervention included diet, exercise, and energy conservation education. Both interventions (30 min/day, 2 days/wk for 8 wk) were delivered online by occupational therapists. OUTCOME AND MEASURES: The primary outcome was the modified Fatigue Impact Scale (mFIS). Outcome measures were collected at baseline, postintervention, and 4- and 8-wk postintervention. RESULTS: At 8 wk postintervention, participants in the MAX group reported significantly lower levels of fatigue impact (mFIS) than those in the HE group, F(1, 107) = 29.54, p = .01; Cohen's d = 0.87; 95% confidence interval [0.18, 1.55]. CONCLUSIONS AND RELEVANCE: These findings provide preliminary evidence that the MAX intervention may decrease the impact of fatigue on daily life among people with post-TBI fatigue. What This Article Adds: An internet-based, self-management intervention combining occupational therapy- delivered energy conservation education with cognitive-behavioral therapy seems to reduce fatigue impact and severity among people with post-TBI fatigue. Future appropriately powered RCTs could positively contribute to the evidence available to occupational therapy practitioners for this chronic, debilitating, and often overlooked symptom.

INTRODUCTION: We aim to assess the trends in trauma patient volume, injury characteristics, and facility resource utilization that occurred during four surges in COVID-19 cases. METHODS: A retrospective cohort study of 92 American College of Surgeons (ACS)-verified trauma centers (TCs) in a national hospital system during 4 COVID-19 case surges was performed. Patients who were directly transported to the TC and were an activation or consultation from the emergency department (ED) were included. Trends in injury characteristics, patient demographics & outcomes, and hospital resource utilization were assessed during four COVID-19 case surges and compared to the same dates in 2019. RESULTS: The majority of TCs were within a metropolitan or micropolitan division. During the pandemic, trauma admissions decreased overall, but displayed variable trends during Surges 1-4 and across U.S. regions and TC levels. Patients requiring surgery or blood transfusion increased significantly during Surges 1-3, whereas the proportion of patients requiring plasma and/or platelets increased significantly during Surges 1-2. Patients admitted to the hospital had significantly higher Injury Severity Score (ISS) and mortality as compared to pre-pandemic during Surge 1 and 2. Patients with Medicaid or uninsured increased significantly during the pandemic. Hospital length of stay (LOS) decreased significantly during the pandemic and more trauma patients were discharged home. CONCLUSIONS: Trauma admissions decreased during Surge 1, but increased during Surge 2, 3 and 4. Penetrating injuries and firearm-related injuries increased significantly during the pandemic, patients requiring surgery or packed red blood cells (PRBCs) transfusion increased significantly during Surges 1-3. The number of patients discharged home increased during the pandemic and was accompanied by a decreased hospital length of stay (LOS).

RATIONALE & OBJECTIVE: Thrice-weekly hemodialysis can result in adequate urea clearance; however, the morbidity and mortality rates of patients treated with maintenance dialysis remain unacceptably high, partly because of nonadherence. African Americans have a higher prevalence of kidney failure treated with dialysis, greater dialysis nonadherence, and higher odds of hospitalization. We hypothesized that more precise ways of assessing dialysis treatment adherence will reflect the severity of nonadherence, distinguish patterns of nonadherence, and inform the design of personalized behavioral interventions. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: African American patients receiving hemodialysis for >90 days. EXPOSURE: Hemodialysis. OUTCOME: Dialysis adherence. ANALYTICAL APPROACH: Dialysis attendance data were displayed using a dot plot, categorized based on missed and shortened treatments, and examined for patterns. Descriptive characteristics were reported. In an exploratory analysis, associations between dialysis treatment adherence and participant characteristics were evaluated using ordinary least squares regression. An analysis was performed using missed minutes of dialysis and current metrics for measuring dialysis treatment adherence (ie, missed and shortened treatments). RESULTS: Among 113 African American patients treated with dialysis, 47% were men; the median age was 57 years (interquartile range, 46-70 years), and the median dialysis vintage was 54 months (interquartile range, 22-90 months). With rows ordered based on the total missed minutes of dialysis, the dot plot displayed a decreasing gradient in the severity of nonadherence, with novel dialysis treatment adherence categories termed as follows: consistent underdialysis, inconsistent dialysis, and consistent dialysis. Distinct patterns of nonadherence and heterogeneity emerged within these categories. Older age was consistently associated with better adherence, as determined by the analyses performed using the total missed minutes of dialysis as well as missed and shortened treatments. LIMITATIONS: The study findings, although replicable and paradigm-shifting, might be limited by the short timeline, focus on adherence data specific to African American patients treated with dialysis, and restriction to dialysis units affiliated with 1 academic center. CONCLUSIONS: This study presents more precise and novel ways of measuring and displaying dialysis treatment adherence. The findings introduce a more personalized approach for evaluating actual dialysis uptake. Identification of unique patterns of adherence behavior is important to inform the design of effective behavioral interventions and improve outcomes for vulnerable African American patients treated with dialysis.
RESUMO
BACKGROUND: The adverse impact of acute hyperglycemia is well documented but its specific effects on nondiabetic trauma patients are unclear. The purpose of this study was to analyze the differential impact of hyperglycemia on outcomes between diabetic and nondiabetic trauma inpatients. METHODS: Adults admitted 2018 to 2019 to 46 Level I/II trauma centers with two or more blood glucose tests were analyzed. Diabetes status was determined from International Classification of Diseases-10th Rev.-Clinical Modification, trauma registry, and/or hemoglobin A1c greater than 6.5. Patients with and without one or more hyperglycemic result >180 mg/dL were compared. Logistic regression examined the effects of hyperglycemia and diabetes on outcomes, adjusting for age, sex, Injury Severity Score, and body mass index. RESULTS: There were 95,764 patients: 54% male; mean age, 61 years; mean Injury Severity Score, 10; diabetic, 21%. Patients with hyperglycemia had higher mortality and worse outcomes compared with those without hyperglycemia. Nondiabetic hyperglycemic patients had the highest odds of mortality (diabetic: adjusted odds ratio, 3.11; 95% confidence interval, 2.8-3.5; nondiabetics: adjusted odds ratio, 7.5; 95% confidence interval, 6.8-8.4). Hyperglycemic nondiabetics experienced worse outcomes on every measure when compared with nonhyperglycemic nondiabetics, with higher rates of sepsis (1.1 vs. 0.1%, p < 0.001), more SSIs (1.0 vs. 0.1%, p < 0.001), longer mean hospital length of stay (11.4 vs. 5.0, p < 0.001), longer mean intensive care unit length of stay (8.5 vs. 4.0, p < 0.001), higher rates of intensive care unit use (68.6% vs. 35.1), and more ventilator use (42.4% vs. 7.3%). CONCLUSION: Hyperglycemia is associated with increased odds of mortality in both diabetic and nondiabetic patients. Hyperglycemia during hospitalization in nondiabetics was associated with the worst outcomes and represents a potential opportunity for intervention in this high-risk group. LEVEL OF EVIDENCE: Therapeutic/care management; Level III.

BACKGROUND: There is a lack of literature regarding the most effective timing to initiate physical therapy (PT) among traumatically injured patients. We aim to evaluate the association between early PT/mobilization versus delayed or late PT/mobilization and clinical outcomes of trauma patients. METHODS: A retrospective cohort analysis of an urban level-I trauma center from 2014 to 2019 was performed. Univariate analyses and multivariable logistic regression were performed with significance defined as P < 0.05. RESULTS: A total of 11,937 patients were analyzed. Among patients without a traumatic brain injury (TBI), late PT initiation times were associated with 60% lower odds of being discharged home without services (P < 0.05), significantly increased hospital and ICU length of stay (H-LOS, ICU-LOS) (P < 0.05), and significantly higher odds of complications (VTE, pneumonia, pressure ulcers, ARDS) (P < 0.001). Among patients with a TBI, late PT initiation time had 76% lower odds of being discharged home without services (P < 0.05) and significantly longer H-LOS and ICU-LOS (P < 0.05) however did not experience significantly higher odds of complications (P > 0.05). CONCLUSIONS: Among traumatically injured patients, early PT is associated with decreased odds of complications, shorter H-LOS and ICU-LOS, and a favorable discharge disposition to home without services. Adoption of early PT initiation/mobilization protocols and establishment of prophylactic measures against complications associated with delayed PT is critical to maximize quality of care and trauma patient outcomes. Multi-center prospective studies are needed to ascertain the impact of PT initiation times in greater detail and to minimize trauma patient morbidity.

OBJECTIVES: To determine the incidence and predictive factors of acute kidney injury (AKI) after off-pump lung transplantation. DESIGN: A retrospective cohort study. SETTING: The operating room and intensive care unit. PARTICIPANTS: Adult patients who underwent lung transplant without cardiopulmonary bypass or extracorporeal membrane oxygenator between 2006 and 2016 at the Vanderbilt University Medical Center. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The presence of postoperative AKI was assessed by the Kidney Disease: Improving Global Outcomes criteria in the first seven postoperative days. Multivariate logistic regression analysis was used to determine the independent predictive factors of AKI. One hundred forty-eight patients were included in the final analysis, of whom 63 (42.6%) subsequently developed AKI: 43 (29.0%) stage 1, ten (6.8%) stage 2, and ten (6.8%) stage 3. Patients who had AKI had a longer hospital length of stay (12 days [interquartile range (IQR): 10-17] vs ten days [IQR: 8-12], p < 0.001). For every one-year increase in age, the odds of AKI decreased by 8% (odds ratio [OR] 0.92, 95% confidence interval [CI]: 0.87-0.98, p = 0.008). The odds of having AKI in patients with bilateral lung transplant was lower than patients with unilateral transplant (OR 0.09, 95% CI: 0.01-0.63, p = 0.015). Additionally, a diagnosis of chronic obstructive pulmonary disease increased the odds of AKI by four-fold compared with a diagnosis of idiopathic pulmonary fibrosis (OR 4.73, 95% CI: 1.44-15.56, p = 0.011). CONCLUSIONS: AKI is a common complication after off-pump lung transplantation and is associated with increased hospital length of stay. Younger age, unilateral lung transplant, and diagnosis of chronic obstructive pulmonary disease are independently associated with AKI.

AIM: Diabetes has been identified as a risk factor for poor outcomes in patients with COVID-19. We examined the association of hyperglycaemia, both in the presence and absence of pre-existing diabetes, with severity and outcomes in COVID-19 patients. METHODS: Data from 74,148 COVID-19-positive inpatients with at least one recorded glucose measurement during their inpatient episode were analysed for presence of pre-existing diabetes diagnosis and any glucose values in the hyperglycaemic range (>180 mg/dl). RESULTS: Among patients with and without a pre-existing diabetes diagnosis on admission, mortality was substantially higher in the presence of high glucose measurements versus all measurements in the normal range (70-180 mg/dl) in both groups (non-diabetics: 21.7% vs. 3.3%; diabetics 14.4% vs. 4.3%). When adjusting for patient age, BMI, severity on admission and oxygen saturation on admission, this increased risk of mortality persisted and varied by diabetes diagnosis. Among patients with a pre-existing diabetes diagnosis, any hyperglycaemic value during the episode was associated with a substantial increase in the odds of mortality (OR: 1.77, 95% CI: 1.52-2.07); among patients without a pre-existing diabetes diagnosis, this risk nearly doubled (OR: 3.07, 95% CI: 2.79-3.37). CONCLUSION: This retrospective analysis identified hyperglycaemia in COVID-19 patients as an independent risk factor for mortality after adjusting for the presence of diabetes and other known risk factors. This indicates that the extent of glucose control could serve as a mechanism for modifying the risk of COVID-19 morality in the inpatient environment.

BACKGROUND: Chemotherapy regimens that include the utilization of gemcitabine are the standard of care in pancreatic cancer patients. However, most patients with advanced pancreatic cancer die within the first 2 years after diagnosis, even when treated with standard of care chemotherapy. This study aims to explore combination therapies that could boost the efficacy of standard of care regimens in pancreatic cancer patients. METHODS: In this study, we used PV-10, a 10% solution of rose bengal, to induce the death of human pancreatic tumor cells in vitro. Murine in vivo studies were carried out to examine the effectiveness of the direct injection of PV-10 into syngeneic pancreatic tumors in causing lesion-specific ablation. Intralesional PV-10 treatment was combined with systemic gemcitabine treatment in tumor-bearing mice to investigate the control of growth among treated tumors and distal uninjected tumors. The involvement of the immune-mediated clearance of tumors was examined in immunogenic tumor models that express ovalbumin (OVA). RESULTS: In this study, we demonstrate that the injection of PV-10 into mouse pancreatic tumors caused lesion-specific ablation. We show that the combination of intralesional PV-10 with the systemic administration of gemcitabine caused lesion-specific ablation and delayed the growth of distal uninjected tumors. We observed that this treatment strategy was markedly more successful in immunogenic tumors that express the neoantigen OVA, suggesting that the combination therapy enhanced the immune clearance of tumors. Moreover, the regression of tumors in mice that received PV-10 in combination with gemcitabine was associated with the depletion of splenic CD11b+Gr-1+ cells and increases in damage associated molecular patterns HMGB1, S100A8, and IL-1α. CONCLUSIONS: These results demonstrate that intralesional therapy with PV-10 in combination with gemcitabine can enhance anti-tumor activity against pancreatic tumors and raises the potential for this strategy to be used for the treatment of patients with pancreatic cancer.

Eaters (consumers of food) are responsible for 60% of waste along the food cycle in developed countries. Programs that target individual and household food waste behavior change are essential to addressing such waste. School cafeterias worldwide offer an opportune microcosm in which to educate on food and nutrition skills and change related behavior. No Scrap Left Behind, a cafeteria food waste diversion program, was developed, piloted, and assessed based on measures of both direct and indirect food waste behavior, and attitudes, knowledge, and emotions related to food waste. Participants had positive attitudes towards food waste reduction, engaged in food waste diversion actions, had some knowledge of the impacts of wasted food, and considered their actions important to waste reduction generally. Food waste per student was decreased by 28% over the course of the first year of programming (p = 0.000967), and by 26% in the following year when measured a week before and a week after programming occurred (p = 0.0218). Results indicate that students were poised for food behavior change and that related programming did impact behavior in the short term. Programming may, therefore, help improve student attitudes and skills to develop long-term change as well, although future research should explore this specifically. In comparison with other research on cafeteria programming, results suggest that food waste diversion programming can positively impact students' dispositions and behaviors, and may be more effective when tailored to the specific population.
