BackgroundThe COVID-19 pandemic resulted in nationwide social distancing and shelter-in-place orders meant to curb transmission of the SARS-CoV-2 virus. The effect of the pandemic on injury patterns has not been well described in the USA. The study objective is to determine the effect of the COVID-19 pandemic on the distribution and determinants of traumatic injuries.MethodsThis retrospective multi-institutional cohort study included all hospital admissions for acute traumatic injury at six community level I trauma centers. Descriptive statistics were used to compare injury causes, diagnoses and procedures over two similar time periods: prepandemic (March 11–June 30, 2019) and pandemic (March 11–June 30, 2020).ResultsThere were 7308 trauma patients included: 3862 (53%) prepandemic and 3446 (47%) during the pandemic. Cause of injury significantly differed by period (p<0.001). During the pandemic, there were decreases in motor vehicle crashes (from 17.0% to 14.0%, p<0.001), worksite injuries (from 5.2% to 4.1%, p=0.02), pedestrian injuries (from 3.0% to 2.2%, p=0.02) and recreational injuries (from 3.0% to 1.7%, p<0.001), while there were significant increases in assaults (6.9% to 8.5%, p=0.01), bicycle crashes (2.8% to 4.2%, p=0.001) and off-road vehicle injuries (1.8% to 3.0%, p<0.001). There was no change by study period in falls, motorcycle injuries, crush/strikes, firearm and self-inflicted injuries, and injuries associated with home-improvement projects. Injury diagnoses differed between time periods; during the pandemic, there were more injury diagnoses to the head (23.0% to 27.3%, p<0.001) and the knee/leg (11.7% to 14.9%, p<0.001). There were also increases in medical/surgical procedures (57.5% to 61.9%, p<0.001), administration of therapeutics/blood products (31.4% to 34.2%, p=0.01) and monitoring (11.0% to 12.9%, p=0.01).DiscussionCauses of traumatic injury, diagnoses, and procedures were significantly changed by the pandemic. Trauma centers must adjust to meet the changing demands associated with altered injury patterns, as they were associated with increased use of hospital resources.Level of evidenceIII (epidemiological).
Severe sepsis, systemic inflammatory response syndrome (SIRS), and traumatic brain injury are frequently associated with hyperglycemia in non-diabetic patients. In patients suffering from any of these conditions, hyperglycemia at admission to an intensive care unit (ICU) is directly correlated with increased mortality or morbidity. Although there was initial enthusiasm for insulin treatment to blood glucose levels below 110 mg/dL in these patients, recent understanding suggests that the potential for hypoglycemic complications make this approach potentially dangerous. More moderate glucose control seems to be more beneficial than the aggressive glucose lowering initially suggested. An important publication has shown that hyperlactatemia accompanying hyperglycemia could be the real culprit in bad outcomes. This suggests that coupling moderate glucose lowering with therapeutic agents which might treat the underlying metabolic disturbances in these conditions may be a better strategy. The key metabolic disturbance in these three conditions seems to be persistent glycolysis as an energy source even in the presence of adequate tissue oxygenation (the Warburg Effect). We look at recent advances in understanding aerobic glycolysis and possibly the action of DPP4 on incretins resulting in insulin dysregulation and suggest key metabolic pathways involved in hyperglycemia regulation.
Intrahepatic cholangiocarcinoma (ICC) is the second most common malignant primary tumor of the liver. It is, though, a rare tumor and little is known regarding its natural history, clinicopathologic characteristics, or the outcomes of surgical therapy. We reviewed the experience of 61 patients with ICC seen by the surgical service at the Mayo Clinic over a 31-year period. Patient demographic and clinical data were recorded, as were survival statistics. Pathologic data were also obtained and patients stratified according to the TNM classification. Twenty-eight patients were resected for cure. Overall, 45 patients died of ICC. Of the patients resected for cure, survival at 3 years was 60%. No pathologic condition was found to be associated with the development of ICC. Overall survival correlated with stage of the tumor. Among patients resected for cure, stage did not correlate with survival. Prognosis for patients with ICC remains poor; resection, though, appears to prolong survival.
BackgroundReports indicate social distancing guidelines and other effects of the COVID-19 pandemic impacted trauma patient volumes and injury patterns. This report is the first analysis of a large trauma network describing the extent of these impacts. The objective of this study was to describe the effects of the COVID-19 pandemic on patient volumes, demographics, injury characteristics, and outcomes.MethodsFor this descriptive, multicenter study from a large, multistate hospital network, data were collected from the system-wide centralized trauma registry and retrospectively reviewed to retrieve patient information including volume, demographics, and outcomes. For comparison, patient data from January through May of 2020 and January through May of 2019 were extracted.ResultsA total of 12 395 trauma patients (56% men, 79% white, mean age 59 years) from 85 trauma centers were included. The first 5 months of 2020 revealed a substantial decrease in volume, which began in February and continued into June. Further analysis revealed an absolute decrease of 32.5% in patient volume in April 2020 compared with April 2019 (4997 from 7398; p<0.0001). Motor vehicle collisions decreased 49.7% (628 from 1249). There was a statistically significant increase in injury severity score (9.0 vs. 8.3; p<0.001). As a proportion of the total trauma population, blunt injuries decreased 3.1% (87.3 from 90.5) and penetrating injuries increased 2.7% (10.0 from 7.3; p<0.001). A significant increase was found in the proportion of patients who did not survive to discharge (3.6% vs. 2.8%; p=0.010; absolute decrease: 181 from 207).DiscussionEarly phases of the COVID-19 pandemic were associated with a 32.5% decrease in trauma patient volumes and altered injury patterns at 85 trauma centers in a multistate system. This preliminary observational study describes the initial impact of the COVID-19 pandemic and warrants further investigation.Level of evidenceLevel II (therapeutic/care management).
