Temporal Trends in Sepsis Incidence and Mortality in Patients With Cancer in the US Population

Background Few population-based studies assess the impact of cancer on sepsis incidence and mortality. Objectives To evaluate epidemiological trends of sepsis in patients with cancer. Methods This retrospective cohort study included adults (≥20 years old) identified using sepsis-indicator International Classification of Diseases codes from the Nationwide Inpatient Sample database (2006-2014). A generalized linear model was used to trend incidence and mortality. Outcomes in patients with cancer and patients without cancer were compared using propensity score matching. Cox regression modeling was used to calculate hazard ratios for mortality rates. Results The study included 13 996 374 patients, 13.6% of whom had cancer. Gram-positive infections were most common, but the incidence of gram-negative infections increased at a greater rate. Compared with patients without cancer, those with cancer had significantly higher rates of lower respiratory tract (35.0% vs 31.6%), intra-abdominal (5.5% vs 4.6%), fungal (4.8% vs 2.9%), and anaerobic (1.2% vs 0.9%) infections. Sepsis incidence increased at a higher rate in patients with cancer than in those without cancer, but hospital mortality rates improved equally in both groups. After propensity score matching, hospital mortality was higher in patients with cancer than in those without cancer (hazard ratio, 1.25; 95% CI, 1.24-1.26). Of patients with sepsis and cancer, those with lung cancer had the lowest survival (hazard ratio, 1.65) compared with those with breast cancer, who had the highest survival. Conclusions Cancer patients are at high risk for sepsis and associated mortality. Research is needed to guide sepsis monitoring and prevention in patients with cancer.

Abstract BackgroundAcute respiratory failure associated with sepsis contributes to higher in-hospital mortality. Intubation and invasive mechanical ventilation is a common rescue procedure. However, the 2016 International Guidelines for Management of Sepsis and Septic Shock does not provide any recommendation on indication nor timing of intubation. Timely intubation may improve outcome. The decision to intubate those patients is often hampered by the fear of further hemodynamic deterioration following intubation. MethodsThis study aimed at evaluating the impact of timely intubation on outcome in sepsis associated respiratory failure. We conducted an ancillary analysis of a prospective registry od adult ICU patients with septic shock admitted to the medical ICU in a tertiary medical center, between April 30th, 2014 and December 31st, 2017. All cases of sepsis with lactate >4 mmol/L, mean arterial pressure <65 mmHg, or vasopressor use after 30 mL/kg fluid boluses and suspected or confirmed infection. Patients who remained hospitalized at 24 hours following sepsis onset were separated into intubated and non-intubated groups. The primary outcome was hospital mortality. Univariate and multivariable analyses were used, adjusted for admission characteristics and stabilization of shock within 6 hours. In a secondary analysis, time-dependent propensity score matching was used to match intubated and non-intubated patients.ResultsWe identified 345 (33%) patients intubated within 24 hours and 707 (67%) not intubated. Intubated patients were younger, transferred more often from an outside facility, had higher severity of illness scores, more lung infection, achieved blood pressure goals more often but less often lactate normalization within 6 hours. The crude in-hospital mortality was higher, 89 (26%) vs. 82 (12%), p<0.001, as were ICU mortality, and ICU and hospital length of stay. After adjustment, intubation showed no effect on hospital mortality but fewer hospital-free days through day 28. After 1:1 propensity score matching, there was no difference in hospital mortality, but fewer hospital-free days in the intubated group. ConclusionsIntubation within 24 hours of sepsis onset was safe and not associated with hospital mortality, but was associated with less 28-day hospital-free days. Intubation should not be discouraged in appropriate patients with septic shock.

Abstract Background: Patients with Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) are recommended to undergo transcatheter arterial chemoembolization (TACE). However, TACE in combination with radiofrequency ablation (RFA) is not inferior to surgical resection (SR), and the benefits of surgical resection (SR) for BCLC stage B HCC remain unclear. Hence, this study aims to compare the impact of SR, TACE+RFA, and TACE on analyzing overall survival (OS) in BCLC stage B HCC. Methods: Overall, 428 HCC patients were included in BCLC stage B, and their clinical data and OS were recorded. OS was analyzed by the Kaplan-Meier method and Cox regression analysis. Results: One hundred forty (32.7%) patients received SR, 231 (53.9%) received TACE+RFA, and 57 (13.3%) received TACE. The OS was significantly higher in the SR group than that in the TACE+RFA group [hazard ratio (HR): 1.78; 95% confidence incidence (CI): 1.15-2.75, p=0.009]. The OS was significantly higher in the SR group than that in the TACE group (HR: 3.17; 95% CI: 2.31-4.36, p<0.0001). Moreover, the OS was significantly higher in the TACE+RFA group than that in the TACE group (HR: 1.82; 95% CI: 1.21-2.74, p=0.004). The cumulative OS rates at 1, 3 and 5 years in the SR, TACE+RFA, and TACE groups were 89.2%, 69.4% and 61.2%, 86.0%, 57.9% and 38.2%, and 69.5%, 37.0% and 15.2%, respectively. After propensity score matching, the SR group still had a higher OS than those of the TACE+RFA and TACE groups. The TACE+RFA group had a higher OS than that of the TACE group. Conclusion: The SR group had higher OS than the TACE+RFA and TACE groups in BCLC stage B HCC. Furthermore, the TACE+RFA group had higher OS than the TACE group.

Abstract Background Multimodality treatment of patients with esophageal adenocarcinoma (EAC) improve survival, but the optimal treatment strategy remains undetermined. The aim of this study was to compare outcomes in patients undergoing neoadjuvant chemotherapy (nCT) and neoadjuvant chemoradiotherapy (nCRT) for EAC. Methods Patients who underwent nCT or nCRT followed by surgery for EAC were identified from a prospective database (2000–2017) and included in this study. After propensity score matching, we compared the impact of the treatments on postoperative complications, in-hospital mortality, pathological outcomes and survival rates. Results Of the 396 eligible patients, 262 patients were analysed following propensity score matching. This resulted in 131 patients in the nCT group versus 131 patients in the nCRT group. There were no significant differences between the nCT and nCRT groups for overall complications (59% vs 57%, P = 0.802) or in-hospital mortality (2% vs 0%, P = 0.156). Patients who had nCRT had more R0 resections (93% vs. 83%, P = 0.013), and a higher pathological complete response rate (15% vs. 5%, P < 0.001). The pattern of recurrence was similar (P = 0.753) and there were no differences in 5-year disease-free survival rates (nCT vs nCRT; 39% vs 39%, P = 0.879) or 5-year overall survival rates (nCT vs nCRT; 44% vs 33%, P = 0.645). Conclusion In this study no differences between nCT and nCRT were seen in postoperative complications and in-hospital mortality in patients treated for EAC. Inspite of improved complete resection and pathological response there was no difference in the overall survival between the treatment modalities.

Objectives: remdesivir is currently approved for the treatment of COVID-19. The recommendation for using remdesivir in COVID-19 was based on the in vitro and in vivo activity of this drug against SARS-CoV-2. Methods: this was a prospective, observational study conducted on a large population of patients hospitalized for COVID-19. The primary endpoint of the study was to evaluate the impact of remdesivir-containing therapy on 30-day mortality; secondary endpoint was the impact of remdesivir-containing therapy on the need of high flow oxygen therapy (HFNC) or non-invasive ventilation (NIV) or mechanical ventilation. Data were analyzed after propensity score matching. Results: 407 patients with SARS-CoV-2 pneumonia were consecutively enrolled. Out of these, 294 (72.2%) and 113 (27.8%) were respectively treated or not with remdesivir. Overall, 61 (14.9%) patients were treated during hospitalization with non-invasive or mechanical ventilation, while a 30-day mortality was observed in 21 (5.2%) patients. Cox regression analysis, after propensity score matching, showed that therapies, including remdesivir-containing therapy, were not statistically associated with 30-day survival or mortality, while need of HFNC/NIV (HR 17.921, CI95% 0.954-336.73, p=0.044) and mechanical ventilation (HR 3.9, CI95% 5.36-16.2, p=0.003) resulted independently associated with 30-day mortality. Finally, therapies including or not remdesivir were not independently associated with lower or higher risk of HFNC/NIV or mechanical ventilation. Conclusions: this real-life experience about the remdesivir use in hospitalized patients with COVID-19 was not associated with significant increase in rates of survival or reduced use of HFNC/NIV or mechanical ventilation, compared to patients treated with other therapies not including remdesivir.

Abstract Background: Hypernatremia is a common complication encountered during the treatment of neurocritically ill patients. However, it is unclear whether clinical outcomes correlate with the severity of hypernatremia in such patients. Therefore, we investigated the impact of hypernatremia on mortality of these patients, depending on the degree of hypernatremia.Methods: Among neurosurgical patients admitted to the intensive care unit (ICU) in a tertiary hospital from January 2013 to December 2019, patients who were hospitalized in the ICU for more than 5 days and whose serum sodium levels were obtained during ICU admission were included. Hypernatremia was defined as the highest serum sodium level exceeding 150 mEq/L observed. We classified the patients into four subgroups according to the severity of hypernatremia and performed propensity score matching analysis.Results: Among 1,146 patients, 353 patients (30.8%) showed hypernatremia. Based on propensity score matching, 290 pairs were included in the analysis. The hypernatremia group had higher rates of in-hospital mortality and 28-day mortality in both overall and matched population (both p < 0.001 and p = 0.001, respectively). In multivariable analysis of propensity score-matched population, moderate and severe hypernatremia were significantly associated with in-hospital mortality (adjusted odds ratio [OR]: 4.58, 95% confidence interval [CI]: 2.15 – 9.75 and adjusted OR: 6.93, 95% CI: 3.46 – 13.90, respectively) and 28-day mortality (adjusted OR: 3.51, 95% CI: 1.54 – 7.98 and adjusted OR: 10.60, 95% CI: 5.10 – 21.90, respectively) compared with the absence of hypernatremia. However, clinical outcomes, including in-hospital mortality and 28-day mortality, were not significantly different between the group without hypernatremia and the group with mild hypernatremia (p = 0.720 and p = 0.690, respectively). The mortality rates of patients with moderate and severe hypernatremia were significantly higher in both overall and matched population. Interestingly, the mild hypernatremia group of matched population showed the best survival rate.Conclusions: Moderate and severe hypernatremia were associated with poor clinical outcomes in neurocritically ill patients. However, the prognosis of patients with mild hypernatremia was similar with that of patients without hypernatremia. Therefore, mild hypernatremia may be allowed during treatment of intracranial hypertension using hyperosmolar therapy.

Abstract Background: To evaluate the impact of primary tumor radiotherapy on survival in patients with unresectable metastatic rectal or rectosigmoid cancer. Methods: Form September 2008 to September 2017, 350 patients with unresectable metastatic rectal or rectosigmoid cancer were retrospectively reviewed in our center. All patients received at least 4 cycles of chemotherapy, and were divided into two groups according to with primary tumor radiotherapy or without. 163 patients received primary tumor radiotherapy, and the median radiation dose was 56.69Gy(50.4-60). Survival curves were estimated from the Kaplan–Meier procedure to roughly compare survival among two groups. Subsequently, 18-month survival was used as the outcome variable for this study. This study mainly evaluated the impact of primary tumor radiotherapy on survival of these patients through a series of multivariate Cox regression analyses after propensity score matching (PSM). Results: The median follow-up time was 21 months. All 350 patients received a median of 7 cycles of chemotherapy (range 4-12), 163 (46.67%) patients received primary tumor radiotherapy for local symptoms. The Kaplan–Meier survival curves showed a significant overall survival (OS) advantage for primary tumor radiotherapy group to without radiotherapy (20.07 vs 17.33 months; P=0.002). In this study, multivariate Cox regression analysis after adjusted covariates, multivariate Cox regression analysis after PSM, and inverse probability of treatment weighting (IPTW) analysis and propensity score (PS)-adjusted model analysis consistently showed that primary tumor radiotherapy could effectively reduce the risk of death for these patients at 18 months (HR: 0.62, 95% CI 0.40-0.98; HR:0.79, 95% CI:0.93-1.45; HR: 0.70, 95% CI 0.55-0.99 and HR: 0.74, 95% CI:0.59-0.94). Conclusion: Compared with patients with stage IV rectal or rectosigmoid cancer who did not receive primary tumor radiotherapy, received primary tumor radiotherapy reduced the risk of death in these patients. The radical doses（59.4Gy/ 33 fractions or 60Gy/ 30 fractions） of radiation for primary tumors might be considered for unresectable metastatic rectal or rectosigmoid cancer, not just for relieve symptoms.

Statin Use

Abstract Purpose The complications of Severe Corona Virus Disease 2019 (COVID-19) are attributed to the overproduction of early response proinflammatory cytokines, causing a systemic hyperinflammatory state. Statins are potentially a potent adjuvant therapy in COVID-19 infection due to their pleiotropic and anti-inflammatory effects, which are independent of their cholesterol-lowering activity. This study investigates the impact of statin use on the outcome of critically ill patients with COVID-19. Methods A multicenter, retrospective cohort study of all adult critically ill patients with confirmed COVID-19 admitted to Intensive Care Units (ICUs) between March 1, 2020, and March 31, 2021. Eligible patients were classified into two groups based on statin use during ICU stay and were matched with a propensity score which was based on patient’s age and admission APACHE II and SOFA scores. The primary endpoint was in-hospital mortality. Other outcomes were considered secondary... Results A total of 1049 patients were eligible; 502 patients were included after propensity score matching (1:1 ratio). The 30-day (hazard ratio 0.75 (95% CI 0.58, 0.98), P = 0.03) and in-hospital mortality (hazard ratio 0.69 (95% CI 0.54, 0.89), P = 0.004) were significantly lower in patients who received statin therapy on multivariable cox proportional hazards regression analysis. Moreover, patients who received statin have a lower risk of hospital-acquired pneumonia (OR 0.48(95% CI 0.32, 0.69), P = < 0.001), lower levels of markers of inflammation on follow up and no increased risk of liver injury. Conclusion The use of statin during ICU stay in COVID-19 critically ill patients may have a beneficial role and survival benefits with a good safety profile.

Abstract Background Thrombocytopenia was reported both detrimental and advantageous to hepatocellular carcinoma (HCC). However, there is little evidence showing clearly the clinical value of preoperative thrombocytopenia on the surgical outcome of patients with small HCC. This retrospective study aimed at elucidating the correlation between preoperative thrombocytopenia and surgical outcome of small HCC patients within Milan criteria treated with liver resection. Methods Data of hepatitis B virus (HBV)-related small HCC patients were retrospectively analyzed, and we performed the propensity score matching (PSM) analysis to overcome the imbalance of clinicopathological features. Patients enrolled were subsequently categorized into two groups according to preoperative platelet counts: thrombocytopenia group and non-thrombocytopenia group. Survival outcomes of the patients in both groups were described with the Kaplan-Meier method, and the difference was compared with a log-rank test. Cox regression analysis was applied to identify the risk factors of surgical outcome. Results After PSM, the estimated 1-, 3-, and 5-year overall survival (OS) rates for small HCC patients in the thrombocytopenia group were 94.5%, 77.0%, and 57.6%, and 95.0%, 79.6%, and 68.0%, respectively, for small HCC patients in the non-thrombocytopenia group (P = 0.042). And the 1-, 3-, and 5-year estimated recurrence-free survival (RFS) rates for small HCC patients in the thrombocytopenia group were 70.4%, 51.0%, and 42.1%, and 83.8%, 63.7%, and 46.7%, respectively, for small HCC patients in the non-thrombocytopenia group (P = 0.035). Multivariate analysis indicated preoperative thrombocytopenia was a significant prognosticator of poor RFS (hazard ratio (HR) = 1.388, 95% confidence interval (CI) 1.028~1.874, P = 0.033). Conclusion Preoperative thrombocytopenia had an undesirable impact on the recurrence of small HCC patients treated with liver resection.

The data were analyzed after propensity score matching. Results: A total of 407 patients with SARS-CoV-2 pneumonia were consecutively enrolled. Out of these, 294 (72.2%) were treated with remdesivir and 113 (27.8%) were not. Overall, 61 patients (14.9%) were treated during hospitalization with HFNC, NIV, or mechanical ventilation, while 30-day mortality was observed in 21 patients (5.2%). Univariate analysis of patients treated with remdesivir or not showed no differences in 30-day mortality (4% vs. 6%, p = 0.411) in the two study groups. Cox regression analysis, after propensity score matching, showed that therapies, including remdesivir-containing therapy, were not statistically associated with 30-day survival or mortality. The Kaplan–Meier curves of 30-day survival in patients treated with remdesivir or not before (p = 0.24) and after (p = 0.88) propensity score matching showed no differences between the two study groups. Finally, patients treated with remdesivir or not showed the same need for HFNC/NIV or mechanical ventilation. Conclusions: This real-life experience of remdesivir use in hospitalized patients with COVID-19 was not associated with significant increases in rates of survival or reduced use of HFNC/NIV or mechanical ventilation compared with patients treated with other therapies not including remdesivir.
