Clinical outcomes of triclosan-coated barbed suture in open hernia repair: a retrospective cohort study.

PURPOSE: We assessed clinical outcomes of patients undergoing open hernia repair using STRATAFIX™ Symmetric, a barbed triclosan-coated suture (TCS; Ethicon), versus conventional polydioxanone suture (PDS) for abdominal wall closure. METHODS: This single-center retrospective cohort study identified patients undergoing hernia repair. The site used PDS from 2013 to 2016 and switched exclusively to barbed TCS in 2017. Outcomes were assessed at 30, 60, and 90 days. Multivariate regression analyses and Cox proportional hazards models were used. RESULTS: Of 821 hernia repairs, 446 used barbed TCS and 375 used conventional PDS. Surgical site infections (SSIs) were significantly less frequent with barbed TCS (60 days, 5.9% vs. 11.4%; P = 0.0083; 90 days, 5.9% vs. 11.7%; P = 0.006) and this remained consistent after multivariate adjustment (60 days, OR [95% CI]: 0.5 [0.3-0.9]; 90 days, 0.5 [0.3-0.9]). Among patients with SSI, deep SSIs were less frequent with barbed TCS (60 days, 9.1% vs. 35.7%; P = 0.022; 90 days, 9.1% vs. 34.9%; P = 0.0252). Barbed TCS significantly reduced the risk of perioperative complications (HR [95% CI]: 0.5[0.3-0.8]; P = 0.0058). Hospital length of stay was 2.5 days shorter with barbed TCS (mean [95% CI]: 5.7[4.9-6.6] vs. 8.2[7.3-9.1] days; P < 0.0001). No differences in reoperation rate over time were observed by type of suture (HR[95% CI]:1.3 [0.5-3.4]; P = 0.4793). CONCLUSIONS: This study showed that patients who underwent open hernia repair appeared to recover equally well regardless of the suture type. In addition, the use of barbed TCS was associated with significantly reduced risk of perioperative complications and hospital length of stay.

Formative evaluation of a teledentistry training programme for oral health professionals.

INTRODUCTION: The objective of this study was to conduct a formative evaluation of a teledentistry (TD) programme that was developed for a predominantly rural state in the Midwestern United States. MATERIALS AND METHODS: Formative evaluation data were collected on programme activities from the TD programme records. In addition, the effectiveness of the TD training programme was evaluated using a self-administered paper-based survey administered to the participants, immediately following completion of the training activity. Ninety-three dental students, oral health and other health professionals participated in the TD training programme. RESULTS: Overall, the trainees rated the TD training programme highly, with regard to the content, format and skills improvement. The evaluation also demonstrated a positive change in all trainees' attitudes following the training sessions, with most trainees acknowledging a positive impact of the training on their knowledge and competency. DISCUSSION AND CONCLUSIONS: We identified challenges in the development of the TD programme and in expanding access to oral health care for rural communities. Challenges included reimbursement and a limited interest amongst established dental offices. Dental schools can play an important role in preparing both dental health professionals and other health professionals in the use of TD by providing training and oral health expertise. The use of TD by non-dental providers for consultation, referral and disease management has the potential to improve oral health outcomes, particularly for rural and underserved populations. Evaluation data provide critical feedback to programme planners and administrators.

The use of solar energy for powering a portable autoclave.

Climate change and the depletion of fossil fuels have forced the developed world to look for clean energy alternatives. Solar cooking is developing in Asian and African countries blessed with ample sun, but is still at an early stage. A portable autoclave was developed in India using this technology. The Prince-40 Concentrator provided adequate capacity to autoclave culture media and treat biomedical waste in a small laboratory set-up, and could save electricity worth Rs. 15,000 (188.10 GBP)/year or LPG worth Rs. 37,500 (470.25 GBP)/year. This technology would be of immense use in health centres in rural areas with frequent power cuts or no power supply.
