Costs and Effects of Abdominal versus Laparoscopic Hysterectomy: Systematic Review of Controlled Trials

Objective: Comparative evaluation of costs and effects of laparoscopic hysterectomy (LH) and abdominal hysterectomy (AH). Data sources: Controlled trials from Cochrane Central register of controlled trials, Medline, Embase and prospective trial registers. Selection of studies: Twelve (randomized) controlled studies including the search terms costs, laparoscopy, laparotomy and hysterectomy were identified. Methods: The type of cost analysis, perspective of cost analyses and separate cost components were assessed. The direct and indirect costs were extracted from the original studies. For the cost estimation, hospital stay and procedure costs were selected as most important cost drivers. As main outcome the major complication rate was taken. Findings: Analysis was performed on 2226 patients, of which 1013 (45.5%) in the LH group and 1213 (54.5%) in the AH group. Five studies scored >= 10 points (out of 19) for methodological quality. The reported total direct costs in the LH group ($63,997) were 6.1$60,114). The reported total indirect costs of the LH group ($1,609) were half of the total indirect in the AH group ($3,139). The estimated mean major complication rate in the LH group (14.3%) was lower than in the AH group (15.9%). The estimated total costs in the LH group were $3,884 versus$3,312 in the AH group. The incremental costs for reducing one patient with major complication(s) in the LH group compared to the AH group was $35,750. Conclusions: The shorter hospital stay in the LH group compensates for the increased procedure costs, with less morbidity. LH points in the direction of cost effectiveness, however further research is warranted with a broader costs perspective including long term effects as societal benefit, quality of life and survival

AD51B in Familial Breast Cancer

Common variation on 14q24.1, close to RAD51B, has been associated with breast cancer: rs999737 and rs2588809 with the risk of female breast cancer and rs1314913 with the risk of male breast cancer. The aim of this study was to investigate the role of RAD51B variants in breast cancer predisposition, particularly in the context of familial breast cancer in Finland. We sequenced the coding region of RAD51B in 168 Finnish breast cancer patients from the Helsinki region for identification of possible recurrent founder mutations. In addition, we studied the known rs999737, rs2588809, and rs1314913 SNPs and RAD51B haplotypes in 44,791 breast cancer cases and 43,583 controls from 40 studies participating in the Breast Cancer Association Consortium (BCAC) that were genotyped on a custom chip (iCOGS). We identified one putatively pathogenic missense mutation c.541C>T among the Finnish cancer patients and subsequently genotyped the mutation in additional breast cancer cases (n = 5259) and population controls (n = 3586) from Finland and Belarus. No significant association with breast cancer risk was seen in the meta-analysis of the Finnish datasets or in the large BCAC dataset. The association with previously identified risk variants rs999737, rs2588809, and rs1314913 was replicated among all breast cancer cases and also among familial cases in the BCAC dataset. The most significant association was observed for the haplotype carrying the risk-alleles of all the three SNPs both among all cases (odds ratio (OR): 1.15, 95% confidence interval (CI): 1.11–1.19, P = 8.88 x 10−16) and among familial cases (OR: 1.24, 95% CI: 1.16–1.32, P = 6.19 x 10−11), compared to the haplotype with the respective protective alleles. Our results suggest that loss-of-function mutations in RAD51B are rare, but common variation at the RAD51B region is significantly associated with familial breast cancer risk

The Knowledge Argument and Howard Robinson’s 2016 case for Dualism and Mental Substance

Standard physicalist responses to Frank Jackson’s Knowledge Argument (1982) are argued to be unsatisfactory. Related arguments are then considered for Mind Body Dualism from Howard Robinson (2016), covering topics of scientific reduction and supervenience. I object to Robinson’s arguments for the mind dependence of various entities

Total laparoscopic hysterectomy versus total abdominal hysterectomy for obese women with endometrial cancer

Obesity is common in endometrial cancer and surgery for these patients is challenging. We compared total laparoscopic hysterectomy (TLH) with total abdominal hysterectomy (TAH) with respect to feasibility (operating time, estimated blood loss, length of hospital stay, and conversion to laparotomy) and safety (perioperative morbidity and mortality) in a retrospective analysis of 78 morbidly obese patients with endometrial cancer. Analysis is based on the intention to treat. The intention to treat was TLH in 47 patients and it could be successfully completed in 42 patients (89.4%). The mean weight for all patients was 118.7 kg, with patients in the TLH group weighing more and having higher ASA scores. Mean operating time and estimated blood loss were similar in both groups. Mean postoperative hospital stay was 4.4 (±3.9) days in the TLH group and 7.9 (±3.0) days in the TAH group (P < 0.0001). Wound infections occurred in 15 of 31 patients (48.4%) in the TAH group and in 1 of 47 patients (2.1%) in the TLH group. All other morbidity, as well as patterns of recurrence and survival were similar in both groups. These data justify a prospective randomized trial comparing TLH with TAH for the treatment of endometrial cancer. © 2005 IGC
