Administration of the mitochondria-targeted anti-oxidant mitoquinone significantly decreased plasma ALT and aspartate aminotransferase in patients with chronic HCV infection, and this suggests that mitoquinone may decrease necroinflammation in the liver in these patients. As mitochondrial oxidative damage contributes to many other chronic liver diseases, such as steatohepatitis, further studies using mitochondria-targeted anti-oxidants in HCV and other liver diseases are warranted.

The effects of pretransplant obesity, diabetes mellitus (DM), coronary artery disease (CAD), and hypertension (HTN) on outcomes after liver transplantation (LT) are controversial. Questions have also been raised about the appropriateness of the body mass index (BMI) for assessing obesity in patients with end-stage liver disease. Both issues have implications for organ allocation in LT. To address these questions, we undertook a cohort study of 202 consecutive patients (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) undergoing LT at a national center in New Zealand. BMI and body fat percentage (%BF) values (dual-energy X-ray absorptiometry) were measured before transplantation, and the methods were compared. The influence of pretransplant risk variables (including obesity, DM, CAD, and HTN) on the 30-day postoperative event rate, length of hospital stay, and survival were analyzed. There was agreement between the calculated BMI and the measured %BF for 86.0% of the study population (j coefficient 5 0.73, 95% confidence interval 5 0.61-0.85), and this was maintained across increasing Model for EndStage Liver Disease scores. Obesity was an independent risk factor for the postoperative event rate [count ratio (CR) 5 1.03, P < 0.001], as was DM (CR 5 1.4, P < 0.001). Obesity with concomitant DM was the strongest predictor of the postoperative event rate (CR 5 1.75, P < 0.001) and a longer hospital stay (5.81 days, P < 0.01). Independent metabolic risk factors had no effect on 30-day, 1-year, or 5-year patient survival. In conclusion, BMI is an adequate tool for assessing obesity-associated risk in LT. Early post-LT morbidity is highest for patients with concomitant obesity and DM, although these factors do not appear to influence recipient survival. Liver Transpl 20:281-290, 2014. V C 2014 AASLD.

Decentralisation is widely practised but its scrutiny tends to focus on structural and authority changes or outcomes. Politics and process of devolution implementation needs to be better understood to evaluate how national governments use the enhanced decision space for bringing improvements in the health system and the underlying challenges faced. We use the example of Pakistan’s radical, politically driven provincial devolution to analyse how national structures use decentralisation opportunities for improved health planning, spending and carrying out transformations to the health system. Our narrative draws on secondary data sources from the PRIMASYS study, supplemented with policy roundtable notes from Pakistan.Our analysis shows that in decentralised Pakistan, health became prioritised for increased government resources and achieved good budgetary use, major strides were made contextualised sector-wide health planning and legislations, and a proliferation seen in governance measures to improve and regulate healthcare delivery. Despite a disadvantaged and abrupt start to devolution, high ownership by politicians and bureaucracy in provincial governments led to resourcing, planning and innovations. However, effective translation remained impeded by weak institutional capacity, feeble federal–provincial coordination and vulnerability to interference by local elites.Building on this illustrative example, we propose (1) political management of decentralisation for effective national coordination, sustaining stable leadership and protecting from political interfere by local elites; (2) investment in stewardship capacity in the devolved structures as well as the central ministry to deliver on new roles.
