170 Background: Cancer patients are vulnerable to influenza viruses and are at great risk of developing related complications. However, few studies have assessed the impact of influenza infection among hospitalized cancer patients in the United States. Methods: We identified cancer-related hospitalizations from National Inpatient Sample between 2012 and 2014. A 1:1 propensity score matching analysis was conducted to compare the clinical outcomes between hospitalized cancer patients with and without influenza. Results: We identified 13,186,849 cancer-related hospitalizations, and 47,850 of them (0.36%) had a concomitant diagnosis of influenza. After propensity score matching, cancer patients with influenza had a higher mortality (5.4% vs. 4.2%; odds ratio [OR]: 1.3; 95% confidence interval [CI], 1.13 to 1.49; P < 0.001), longer length of stay (6.3 vs. 5.6 days; P < 0.001) but lower costs (14605.9 vs. 14625.5 dollars; P < 0.001) in hospital than those without influenza. In addition, patients with influenza had a higher incidence of pneumonia (18.4% vs. 13.2%; OR, 1.49; 95% CI, 1.37 to 1.62; P < 0.001), neutropenia (7.1% vs. 3.4%; OR, 2.18; 95% CI, 1.91 to 2.50; P < 0.001), sepsis (19.5% vs. 9.3%; OR, 2.36; 95% CI, 2.16 to 2.58; P < 0.001), dehydration (14.8% vs. 8.8%; OR, 1.80; 95% CI, 1.65 to 1.97; P < 0.001), and acute kidney injury (19.9% vs. 17.6%; OR, 1.16; 95% CI, 1.08 to 1.25; P < 0.001) than those without influenza. Conclusions: Influenza is associated with worse clinical outcomes among hospitalized cancer patients. Influenza vaccination is recommended in this population.

BackgroundPatients with malignancy are vulnerable to influenza viruses and are at high risk of developing serious complications. However, few studies have investigated the impact of influenza infection among hospitalised patients with malignancy.MethodsCancer-related hospitalisations were identified by using data from National Inpatient Sample in the USA between 2012 and 2014. We conducted a 1:1 propensity score matching analysis to compare the in-hospital outcomes between cancer patients with and without influenza. Multivariate logistic regression analyses were also performed to identify independent prognosis predictors of mortality.ResultsWe identified 13 186 849 weighted cancer-related hospitalisations during the study period, and 47 850 of them (0.36%) had a concomitant diagnosis of influenza. After propensity score matching, cancer patients with concomitant influenza had a higher mortality (5.4% vs 4.2%; OR, 1.30; 95% CI, 1.13 to 1.49; p<0.001), longer length of stay (6.3 days vs 5.6 days; p<0.001) but lower costs (US$14 605.9 vs US$14 625.5; p<0.001) in hospital than those without influenza. In addition, cancer patients with influenza had a higher incidence of complications, including pneumonia (18.4% vs 13.2%; OR, 1.49; 95% CI, 1.37 to 1.62; p<0.001), neutropenia (7.1% vs 3.4%; OR, 2.18; 95% CI, 1.91 to 2.50; p<0.001), sepsis (19.5% vs 9.3%; OR, 2.36; 95% CI, 2.16 to 2.58; p<0.001), dehydration (14.8% vs 8.8%; OR, 1.80; 95% CI, 1.65 to 1.97; p<0.001) and acute kidney injury (19.9% vs 17.6%; OR, 1.16; 95% CI, 1.08 to 1.25; p<0.001) than those without influenza. Older age, no insurance, more comorbidities, lung cancer and haematological malignancy were independently associated with higher mortality.ConclusionInfluenza is associated with worse in-hospital clinical outcomes among hospitalised patients with malignancy. Annual influenza vaccination and early initiation of antiviral therapy are recommended in this high-risk population.

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: The effect of previous malignancy history on the survival of individuals with a second primary gallbladder cancer remains unclear. Therefore, this study was conducted to analyze the impact of previous malignancy history on the survival of individuals with gallbladder cancer and to compare the prognostic differences between gallbladder cancer patients with and without previous cancer.Methods: Extract the United States Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2015 for cases diagnosed with gallbladder cancer. The Kaplan-Meier curves and log-rank test were used to compare the survival difference between gallbladder cancer individuals with and without previous malignancy. Cox proportional hazards regression model was used to explore the risk factors of gallbladder cancer.Results: A total of 5861 patients with gallbladder cancer were enrolled, including 5622 (95.9%) patients without prior primary cancer and 239 (4.1%) patients with prior primary cancer. Patients with gallbladder cancer with prior primary malignancy were older, and the tumors were at localized and regional stages more frequently and more early stages. The Kaplan-Meier curves showed that gallbladder cancer patients with prior cancer had better overall survival (OS) (P=0.027) and gallbladder cancer-specific survival (GCSS) (P<0.001) before propensity score matching (PSM), and gallbladder cancer patients with prior cancer had better GCSS (P<0.001), and there was no difference in OS (P=0.113) between gallbladder cancer patients with and without prior cancer after PSM. Multivariable cox regression analysis revealed that prior malignancy history was not a risk factor for OS (HR=0.875, 95%CI: 0.752-1.018, P=0.084), but it was beneficial to GCSS (HR=0.404, 95%CI: 0.318-0.513, P<0.001).Conclusions: Gallbladder cancer individuals with previous primary malignancy have different clinical characteristics from those without previous primary malignancy. Gallbladder cancer patients with previous primary malignancy have better progress than those without previous malignancy.

Aims: This study aimed to retrospectively determine the influence factors and survival effects of chemotherapy in pathological T3N0M0 esophageal cancer (EC) patients based on histological type. Methods: A total of 1136 pathological T3N0M0 EC patients who had surgery were chosen from the Surveillance, Epidemiology and End Results database. The patients were divided into subgroups based on histological type and chemotherapy status. Multivariate logistic regression, log-rank test and Cox regression were used to identify prognostic risk factors and survival differences. A propensity score matching analysis was applied to adjust the covariates. The impact of additional chemotherapy was also assessed in patients who had postoperative radiotherapy. Results: The 5-year overall survival was 36.4% for all patients. Chemotherapy was an independent protective factor of survival in both adenocarcinoma and squamous cell carcinoma patients. In the survival analysis, chemotherapy significantly improved the prognosis of EC patients, both for adenocarcinoma and squamous cell carcinoma. Propensity score matching analysis validated these results. Conclusion: Chemotherapy is recommended for pathological T3N0M0 EC patients regardless of histological type.
