Comparison of sexual behavior data collected using a coital diary and a clinic-based interview during a microbicide pilot study in Mwanza, Tanzania.
BACKGROUND: The performance of coital diaries (CDs) and clinic-based interviews to measure sexual behavior was compared during a pilot study for a Phase III microbicide trial. METHODS: In Mwanza, 59 women were enrolled for 4 weeks and provided with 20 placebo gels. Weekly, women were given CDs to complete daily. At the final clinic visit, women attended a face-to-face interview (Clinic FFI) about their sexual behavior, and the gel use was accounted for (gel accountability (GA)). Comparisons were made between CD, Clinic FFI, and GA data. In-depth interviews following clinic visits elicited reasons for discrepancies in reports. RESULTS: Twice as many sex acts during 1 week were recorded in the CD (median 4) compared with the clinic FFI (median 2). At the clinic FFI, more women reported using the gel for each sex act (84% vs. 40%; P < 0.001) and vaginal washing for each sex act (98% vs. 56%; P < 0.001) compared with the CD. Over 4 weeks, 16.4% of women recorded sex during menstruation in CDs compared with 1.8% at the clinic visit (P = 0.01). The median number of gels used reported in the CDs was the same as the GA (10) with 59% agreement on the number used within +/-2 gels. Reasons for misreporting during clinic FFI were reported to have been poor recall, embarrassment, or misunderstanding. Inaccuracies in CDs were attributed to misunderstanding or poor recording. CONCLUSIONS: CDs elicited higher recording of sex acts and lower reporting of gel use than clinic FFIs, which has implications for measuring adherence during clinical trials. With clear instructions and support, coital dairies should be considered in future microbicide trial design
Applications of robotics in floating offshore wind farm operations and maintenance: Literature review and trends
Marine operations required to transfer technicians and equipment represent a significant proportion of the total cost of offshore wind. The profile of sites being considered for floating offshore wind farms (FOWFs), e.g., further from the shore and in harsher environments, indicates that these costs need to be assessed by taking into account the maintenance requirements and restricted weather windows. There is an immediate need to investigate the potential use of robotic systems in the wind farm's operations and maintenance (O&M) activities, to reduce the need for costly manned visits. The use of robotic systems can be critical, not only to replace repetitive activities and bring down the levelised cost of energy but also to reduce the health and safety risks by supporting human operators in performing the desired inspections. This paper provides a review of the state of the art in the applications of robotics for O&M of FOWFs. Emerging technology trends and associated challenges and opportunities are highlighted, followed by an outline of the agenda for future research in this domain. </p

Safety and efficacy of non-steroidal anti-inflammatory drugs to reduce ileus after colorectal surgery
Background: Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non-steroidal anti-inflammatory drugs (NSAIDs) for reducing ileus after surgery. Methods: A prospective multicentre cohort study was delivered by an international, student- and trainee-led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a centre-specific survey of compliance to enhanced recovery principles. Secondary safety outcomes included anastomotic leak rate and acute kidney injury. Results: A total of 4164 patients were included, with a median age of 68 (i.q.r. 57\u201375) years (54\ub79 per cent men). Some 1153 (27\ub77 per cent) received NSAIDs on postoperative days 1\u20133, of whom 1061 (92\ub70 per cent) received non-selective cyclo-oxygenase inhibitors. After adjustment for baseline differences, the mean time to gastrointestinal recovery did not differ significantly between patients who received NSAIDs and those who did not (4\ub76 versus 4\ub78 days; hazard ratio 1\ub704, 95 per cent c.i. 0\ub796 to 1\ub712; P = 0\ub7360). There were no significant differences in anastomotic leak rate (5\ub74 versus 4\ub76 per cent; P = 0\ub7349) or acute kidney injury (14\ub73 versus 13\ub78 per cent; P = 0\ub7666) between the groups. Significantly fewer patients receiving NSAIDs required strong opioid analgesia (35\ub73 versus 56\ub77 per cent; P < 0\ub7001). Conclusion: NSAIDs did not reduce the time for gastrointestinal recovery after colorectal surgery, but they were safe and associated with reduced postoperative opioid requirement
