Background. Increased pneumococcal loads are associated with severe outcomes. We determined the prevalence of pneumococcal DNA in blood specimens from patients hospitalized with acute lower respiratory tract infection and identified factors associated with invasive pneumococcal pneumonia, bacterial loads, and death.Methods. A total of 8523 patients were enrolled as part of prospective hospital-based surveillance. Blood was collected for quantitative pneumococcal (lytA) detection, and nasopharyngeal specimens were collected for detection of influenza virus and other respiratory viruses by real-time polymerase chain reaction.Results. Of 6396 cases (75%) with lytA results, 422 (7%) were positive for pneumococcal DNA. The prevalences of human immunodeficiency virus (HIV) and influenza virus were 51% (2965/5855) and 8% (485/6358), respectively. On multivariable analysis, HIV infection (adjusted odds ratio [aOR], 2.4; 95% confidence interval [CI], 1.6-3.6), influenza virus coinfection (aOR, 1.4; 95% CI, 1.2-2.1), oxygen therapy during admission (aOR, 1.6; 95% CI, 1.1-2.3) and in-hospital death (aOR, 2.1; 95% CI, 1.1-4.0) were significantly associated with increased pneumococcal load. Among lytA-positive patients, after adjustment for length of hospitalization, duration of symptoms, and oxygen therapy during admission, pneumococcal loads ≥10,000 DNA copies/mL (aOR, 3.6; 95% CI, 1.8-7.2) were associated with increased risk of death.Conclusions. HIV and influenza virus infections were associated with elevated pneumococcal loads, which, in turn, were associated with increased risk of death.

组、Lucentis组视敏度分别提高3dB、2.7dB。在局灶性DME的18眼，视敏度平均改善1.4dB，与注射前相比差异无统计学意义，而弥漫DME视敏度提高3.4dB，差异具有统计学意义。内核层、外核层、浆液性视网膜脱离以及硬性渗出与视敏度改变无明显相关。

血友病 A 患者中减少为防止出血而进行的必要的输注次数。通过工程改造技术，该药物可以潜在延长血液中 FVIII 的活性，同时通过特定位点的聚乙二醇化技术，使聚乙二醇分子始终如一地与因子 VIII 蛋白连结在一起，从而阻止血液凝固。该公司称，延长半衰期的重组因子 VII 疗法可减少血友病 A 患者的输注的频次。FDA
