RESUMO
OBJECTIVE: The clinical characteristics of various adenovirus (ADV) infection are underexplored up till now. To investigate the risk factors, manifestation, current status of ADV species, treatment and prognosis of this disease. METHODS: We performed a Pubmed and Embase systematic review for case report reporting the ADV infection to analyze the clinical characteristics of disease. RESULTS: Initial database searched identified articles of which 168 (228 cases) were included in the final analysis. Previous solid organ transplantation [odds ratio (OR) = 3.45, 95% CI 1.31-9.08, P = 0.01], hematopoietic stem cell transplant (OR = 4.24, 95% CI 1.33-13.51, P = 0.01) and hematological malignancy (OR = 4.78, 95% CI 1.70-13.46, P = 0.01) were associated with increased risk of disseminated ADV infection. Use of corticosteroids (OR = 3.86, 95% CI 1.21-12.24, P = 0.02) was a significant risk factor for acquiring urinary tract infections. A total of six species (21 types) of ADV infection have been identified in 100/228 (43.9%) cases. ADV B was the most common species. ADV B species (26/60, 52.0% or 5/41, 12.2% P = 0.001) were more isolated in patients with ADV pneumonia. ADV C (13/15, 86.7% versus 35/86, 40.7% P = 0.001) species were more identified in patients with disseminated disease. The species associated with keratoconjunctivitis is only ADV D in our analysis. Urinary tract ADV infections were observed in ADV A/B/D species. Cidofovir (CDV) (82/228, 36.0%) remained the most commonly antiviral therapy in our cases, followed by ribavirin (15/228, 6.6%), ganciclovir (18/228, 7.9%), and brincidofovir (12/228, 5.3%). Brincidofovir was administered as salvage therapy in 10 cases. Death was reported in 81/228 (35.5%) patients. Mortality rate was higher among patients with gastrointestinal (GI) ADV infection (5/10, 50.0%), ADV pneumonia (20/45, 44.4%) and disseminated ADV infection (53/122, 43.4%). CONCLUSION: Previous solid organ transplantation, hematopoietic stem cell transplant and hematological malignancy were risk factors for disseminated ADV infection. Use of corticosteroids was significant for urinary tract ADV infection. Different species correlated with different clinical manifestations of infection. Mortality rate was higher among patients with GI disease, pneumonia and disseminated disease. Our review clarified the current treatment of ADV infections, and more treatment required further investigation.

BACKGROUND: Liver cancer is a common cancer with poor prognosis in China. In this study, the national population-based cancer registration data were used to evaluate and analyze liver cancer incidence and mortality in China in 2011 and provide a reference for liver cancer prevention and control. METHODS: We collected and evaluated the incidence and mortality data of liver cancer in 2011 from 177 cancer registries with qualified data. These data were used in the final analysis including calculating crude, standardized, and truncated incidences and mortalities, and estimated new liver cancer cases and deaths using age-specific rates and the corresponding populations. The national census in 2000 and Segi's population were used for age-standardized rates. RESULTS: The estimates of new liver cancer cases and deaths were 355,595 and 322,416, respectively, in China in 2011. The crude incidence, age-standardized rate of incidence by Chinese standard population (ASRIC), and age-standardized rate of incidence by world standard population (ASRIW) of liver cancer were 26.39/100,000, 19.48/100,000, and 19.10/100,000, respectively; the crude mortality, age-standardized rate of mortality by Chinese standard population (ASRMC), and age-standardized rate of mortality by world standard population (ASRMW) of liver cancer were 23.93/100,000,17.48/100,000, and 17.17/100,000, respectively. The incidence and mortality were higher in rural areas than in urban areas and higher in males than in females. The age-specific incidence and mortality of liver cancer increased greatly with age, particularly after 30 years and peaked at 80-84 or 85+ years. CONCLUSIONS: Liver cancer is a common cancer in China, particularly for males and residents in rural areas. Targeted prevention, early detection, and treatment programs should be carried out.

OBJECTIVES: Clinical experience with ceftazidime-avibactam (CAZ-AVI) for the treatment of carbapenem-resistant Klebsiella pneumoniae (CR-KP) infections is not well evaluated. The aim of this study was to assess its efficacy in a single-centre cohort of patients infected with CR-KP. METHODS: We conducted a retrospective observational study of consecutive patients treated for >72 h with CAZ-AVI or other active antibiotics (OAAs) for CR-KP infections. The primary outcome was 30-d mortality. The secondary outcomes were 14-d clinical failure and 14-d microbiological failure. Multivariate regression and propensity score matching were used to evaluate the relationship between CAZ-AVI treatment and outcomes. RESULTS: Ninety infections caused by CR-KP were documented in our study. Forty-two patients were treated with CAZ-AVI and 48 with OAAs. The crude 30-d mortality (8/42 vs. 22/48, P=0.007), 14-d clinical failure (14/42 vs. 24/48, P=0.046) and 14-d microbiological failure (11/42 vs. 15/48, P=0.034) were significantly lower in patients with CAZ-AVI treatment. The Kaplan-Meier survival curves of 30-d mortality confirmed the findings (logrank=0.004). In the multivariable models, the odds ratio (OR) of 30-d mortality (OR 0.23 95% CI 0.10-0.51, P<0.000), 14-d clinical failure (OR 0.37, 95% CI 0.14-0.95, P=0.039) and 14-d microbiological failure (OR 0.17, 95% CI 0.08-0.93, P=0.038) remain consistently significant. In the subgroup analysis, CAZ-AVI was associated with decreased 30-d mortality in the positive blood culture (OR 0.23, 95% CI 0.08-0.63, P=0.004), septic shock (OR 0.23, 95% CI 0.07-0.78, P=0.019), SOFA score (>5, OR 0.13, 95% CI 0.04-0.36, P<0.000), mechanical ventilation (OR 0.13, 95% CI 0.04-0.36, p<0.000) and Charlson comorbidity index (>3, OR 0.15, 95% CI 0.04-0.55, P=0.004). After propensity score matching, 29 cases from each group were well matched. The 30-d mortality remained significantly lower in the CAZ-AVI group (6/29 vs. 13/29, P=0.05). CONCLUSION: CAZ-AVI may be a more valuable therapeutic option for severe CR-KP infections than for mild cases and further randomized controlled trials are needed to evaluate the efficacy.

BACKGROUND: Breast cancer is the most common cancer among women. Population-based cancer registration data from the National Central Cancer Registry were used to analyze and evaluate the incidence and mortality rates in China in 2013, providing scientific information for cancer prevention and control. METHODS: Pooled data were stratified by area (urban/rural), gender, and age group. National new cases and deaths were estimated using age-specific rates and the corresponding population in 2013. The Chinese population in 2000 and Segi's world population were used to calculate age-standardized rates. RESULTS: The estimated number of new breast cancer cases was about 278 800 in China in 2013. The crude incidence, age-standardized rate of incidence by Chinese standard population, and age-standardized rate of incidence by world standard population were 42.02/100 000, 30.41/100 000, and 28.42/100 000, respectively. The estimated number of breast cancer deaths was about 64 600 in China in 2013. The crude mortality, age-standardized rate of mortality by Chinese standard population, and age-standardized rate of mortality by world standard population were 9.74/100 000, 6.54/100 000, and 6.34/100 000, respectively. Both incidence and mortality were higher in urban than in rural areas. Age-specific breast cancer incidence significantly increased with age, particularly after age 20, and peaked at 50-55 years, while age-specific mortality increased rapidly after 25 years, peaking at 85+ years. CONCLUSIONS: Breast cancer is the most common cancer in Chinese women, especially women in urban areas. Comprehensive measures are needed to reduce the heavy burden of breast cancer.
