TL;DR: Portal vein embolization enables safe and potentially curative extended hepatectomy in a subset of patients who would otherwise be marginal candidates for resection based on a small liver remnant size.
Abstract: Hypothesis: Preoperative portal vein embolization (PVE) allows potentially curative hepatic resection without additional morbidity or mortality in patients with hepatobiliary malignancies who are marginal candidates for resection based on small liver remnant size. Design: A retrospective review of a consecutive series of patients in a multi-institutional database who underwent extended hepatectomy. Setting: University-based referral centers. Patients: Forty-two patients underwent preoperative determination of the future liver remnant (FLR) volume before extended hepatectomy (≥5 segments) for hepatobiliary malignancy without chronic underlying liver disease. Patients were stratified by treatment with or without preoperative PVE. Intervention: Preoperative percutaneous PVE. Maim Outcome Measures: Clinical characteristics, FLR volume, operative morbidity, and survival. Results: There was no difference between the groups that did and did not undergo PVE for the number of tumors, tumor size, estimated blood loss, duration of the operation, complexity of resection, or surgical margins. The FLR at presentation was significantly smaller in patients who underwent PVE than in patients who did not undergo PVE (18% vs 23%; P<.001). After PVE, FLR volumes increased significantly (P=.003); preoperative FLR volumes were similar in both groups (patients who underwent PVE, 25%; and patients who did not undergo PVE, 23%). There was no perioperative mortality and no statistical difference in the incidence of perioperative complications between those who did and those who did not undergo PVE (5 [28%] of 18 patients vs 5 [21%] of 24 patients). The overall 3-year survival was 65% and the median survival duration was equivalent in the 2 groups (40 vs 52 months for those who did vs those who did not undergo PVE). Conclusion: Portal vein embolization enables safe and potentially curative extended hepatectomy in a subset of patients who would otherwise be marginal candidates for resection based on a small liver remnant size.

TL;DR: It is found that rapamycin-induced autophagy enhanced Ag85B presentation by APCs infected with wild-type Mycobacterium tuberculosis H37Rv, H37 Rv-derived ΔfbpA attenuated candidate vaccine or BCG and enhanced immunogenicity in mice, suggesting that vaccine efficacy can be enhanced by augmenting Autophagy-mediated antigen presentation.
Abstract: The variable efficacy of Bacille Calmette Guerin (BCG) vaccination against tuberculosis has prompted efforts to improve the vaccine. In this study, we used autophagy to enhance vaccine efficacy against tuberculosis in a mouse model. We examined the effect of autophagy on the processing of the immunodominant mycobacterial antigen Ag85B by antigen presenting cells (APCs), macrophages and dendritic cells (DCs). We found that rapamycin-induced autophagy enhanced Ag85B presentation by APCs infected with wild-type Mycobacterium tuberculosis H37Rv, H37Rv-derived DeltafbpA attenuated candidate vaccine or BCG. Furthermore, rapamycin enhanced localization of mycobacteria with autophagosomes and lysosomes. Rapamycin-enhanced antigen presentation was attenuated when autophagy was suppressed by 3-methyladenine or by small interfering RNA against beclin-1. Notably, mice immunized with rapamycin-treated DCs infected with either DeltafbpA or BCG showed enhanced T helper type 1-mediated protection when challenged with virulent Mycobacterium tuberculosis. Finally, overexpression of Ag85B in BCG induced autophagy in APCs and enhanced immunogenicity in mice, suggesting that vaccine efficacy can be enhanced by augmenting autophagy-mediated antigen presentation.

TL;DR: It is recommended that all pregnant women be screened for the presence of bacteriuria at their first prenatal visit because as many as one third will experience a recurrence of urinary tract infections.

TL;DR: Preventable adverse events were more common among elderly patients, probably because of the clinical complexity of their care rather than age based discrimination and should be targets for efforts to prevent errors.
Abstract: Objectives: To determine the incidence and types of preventable adverse events in elderly patients. Design: Review of random sample of medical records in two stage process by nurses and physicians to detect adverse events. Two study investigators then judged preventability. Setting: Hospitals in US states of Utah and Colorado, excluding psychiatric and Veterans Administration hospitals. Subjects: 15 000 hospitalised patients discharged in 1992. Main outcome measures: Incidence of preventable adverse events (number of preventable events per 100 discharges) in elderly patients (65 years old) and non-elderly patients (16-64 years). Results: When results were extrapolated to represent all discharges in 1992 in both states, non-elderly patients had 8901 adverse events (incidence 2.80% (SE 0.18%)) compared with 7419 (5.29% (0.37%)) among elderly patients (P=0.001). Non-elderly patients had 5038 preventable adverse events (incidence 1.58% (0.14%)) compared with 4134 (2.95% (0.28%)) in elderly patients (P=0.001). Elderly patients had a higher incidence of preventable events related to medical procedures (such as thoracentesis, cardiac catheterisation) (0.69% (0.14%) v 0.13% (0.04%)), preventable adverse drug events (0.63% (0.14%) v 0.17% (0.05%)), and preventable falls (0.10% (0.06%) v 0.01% (0.02%)). In multivariate analyses, adjusted for comorbid illnesses and case mix, age was not an independent predictor of preventable adverse events. Conclusion: Preventable adverse events were more common among elderly patients, probably because of the clinical complexity of their care rather than age based discrimination. Preventable adverse drug events, events related to medical procedures, and falls were especially common in elderly patients and should be targets for efforts to prevent errors.
