Abstract

Background
Anatomical resection of segment VIII (SVIII) is technically demanding. Only two small studies have published short-term outcomes. The aim of the present study was to evaluate short- and long-term outcomes after anatomical resection involving SVIII for hepatocellular carcinoma (HCC), and to compare long-term outcomes with those after non-anatomical resection of SVIII.

Methods
Outcomes after anatomical resection of SVIII or its subsegments for HCC were compared with those in patients who underwent primary non-anatomical resection of SVIII during the same period.

Results
A total of 154 patients underwent anatomical resection involving SVIII and 122 had non-anatomical resection. In patients undergoing anatomical resection, the preoperative indocyanine green retention rate at 15 min ranged from 2·9 to 32·2 (median 13·6) per cent, and was 10 per cent or more in 109 patients (70·8 per cent). Median duration of operation and blood loss were 378 min and 705 ml respectively. There were no postoperative deaths, but major adverse events occurred in ten patients (6·5 per cent). The cumulative 5-year recurrence-free and overall survival rates were 28·5 and 79·6 per cent, which were significantly better than rates of 19·4 and 64·8 per cent respectively after non-anatomical resection (P = 0·036 and P &lt; 0·001).

Conclusion
Complete resection of SVIII or its subsegments can be performed safely and the long-term outcomes seem acceptable. This can be a curative procedure for HCC, especially in patients with limited liver function reserve, in whom right hepatectomy or right paramedian sectorectomy might otherwise be needed.
Maternal smoking during pregnancy and self‐reported delinquency by offspring
Authors: Ellis Lee , Widmayer Alan , Das Shyamal 
Published: June 2012

ABSTRACTBackgroundSeveral studies have reported significant positive correlations between smoking during pregnancy by mothers and the involvement of their offspring in criminal/delinquent behaviour later in life, but these findings have been described as modest and the criminality based on official conviction statistics.AimsWe sought to verify this relationship and probe for more details on the basis of self‐reported offending among college students.MethodsIndependently completed questionnaires were collected from 6332 students and their mothers. The students provided information about their delinquent acts, if any, according to eight categories. Their mothers provided retrospective reports of their smoking habits, if any, during pregnancy.FindingsMothers who recalled having smoked during pregnancy were significantly more likely than non‐smoking mothers to have offspring who self‐reported engaging in some types of delinquency. This relationship was more evident for female offspring than for male offspring and was most pronounced for illegal drug use by the offspring. There was, however, no relationship between offspring offending and estimated number of cigarettes smoked by mothers, month of pregnancy when smoked or consistency of smoking throughout pregnancy.ConclusionOverall, our study confirms that maternal smoking during pregnancy is associated with offspring involvement in delinquency, but the lack of critical timing or dose–response relationships between maternal smoking and later offspring delinquency cast doubt on the possibility that the associations are due to teratogenic effects of tobacco smoke.
