Porcine circovirus 2 (PCV2) is currently considered an important etiologic agent of swine and its infection has potentially serious economic impact on the swine industry worldwide. This virus is frequently associated with postweaning multisystemic wasting syndrome (PMWS), and also with other clinical conditions such as porcine dermatitis and nephropathy syndrome (PDNS), late-term abortions, reproductive failure in sows, proliferative and necrotizing pneumonia and congenital tremors. The term porcine circovirus-associated disease (PCVAD) is currently used to refer to any of these diseases when they are associated with PCV2 infection. The PCV2 was recognized as a pathogen in 1997, and many questions regarding its biology and pathogenesis remain unanswered. Currently, some studies have shown the production of new vaccine candidates and field efficacy testing of commercial vaccines. This review discusses some major points concerned with immunopathogenesis and vaccines for PCV2 infection.

AIM: To describe the intensive care unit(ICU) outcomes of critically ill cancer patients with Acinetobacter baumannii(AB) ***: This was an observational study that included 23 consecutive cancer patients who acquired AB infections during their stay at ICU of the National Cancer Institute of Mexico(INCan), located in Mexico City. Data collection took place between January 2011, and December 2012. Patients who had AB infections before ICU admission, and infections that occurred during the first 2 d of ICU stay were excluded. Data were obtained by reviewing the electronic health record of each patient. This investigation was approved by the Scientific and Ethics Committees at INCan. Because of its observational nature, informed consent of the patients was not ***: Throughout the study period, a total of 494 critically ill patients with cancer were admitted to the ICU of the INCan, 23(4.6%) of whom developed AB infections. Sixteen(60.9%) of these patients had hematologic malignancies. Most frequent reasons for ICU admission were severe sepsis or septic shock(56.2%) and postoperative care(21.7%). The respiratory tract was the most frequent site of AB infection(91.3%). The most common organ dysfunction observed in our group of patients were the respiratory(100%), cardiovascular(100%), hepatic(73.9%) and renal dysfunction(65.2%). The ICU mortality of patients with 3 or less organ system dysfunctions was 11.7%(2/17) compared with 66.6%(4/6) for the group of patients with 4 or more organ system dysfunctions(P = 0.021). Multivariate analysis identified blood lactate levels(BLL) as the only variable independently associated with inICU death(OR = 2.59, 95%CI: 1.04-6.43, P = 0.040). ICU and hospital mortality rates were 26.1% and 43.5%, ***: The mortality rate in critically ill patients with both HM, and AB infections who are admitted to the ICU is high. The variable most associated with increased mortality was a BLL ≥ 2.6 mmol/L in
