Stable hemoglobin concentration with fecal immunochemical test at high temperatures in a Caribbean colorectal cancer screening program.

BACKGROUND AND AIMS: High temperatures may reduce fecal immunochemical test (FIT) positivity and colorectal cancer (CRC) detection sensitivity. We investigated the effect of temperature on hemoglobin concentration [Hb], in the FOB Gold®. Additionally, we examined FIT pick-up, storage, return times and specimen collection. MATERIALS AND METHODS: In vitro experiments with buffer containing FIT devices, inoculated with Hb-spiked stool. For 7 days, 144 samples were stored in groups of 36 at 4 °C, 22 °C, 30 °C, and 50 °C. Additionally, 54 samples were stored in groups of 18 at 34 °C, 42 °C and 50 °C for 20 h. Paired t-tests and repeated measure ANOVA assessed [Hb] change. Sixty-five screening participants completed a FIT-handling questionnaire. RESULTS: After 7 days, mean [Hb] was stable at 30 °C (0.8 µg Hb/g;95 %CI: -1.5 to 3.1;p = 0.50). For 50 °C, mean [Hb] decreased within 2 days (-21.3 µg Hb/g;95 %CI: -30.2 to -12.5;p < 0.001) and after 20 h (-63.0 µg Hb/g;95 %CI: -88.7 to -37.3;p < 0.001), respectively. All other temperature categories showed significant mean [Hb] increase. Same-day FIT return was reported by 80 %. Eighty-seven percent experienced specimen collection as easy and 33 % kept the FIT refrigerated after collection. CONCLUSIONS: The FOB Gold® is suitable for CRC screening in tropical climates. Although most respondents indicated same-day sample return, we recommend avoiding FIT storage above 30 °C for longer than7 days.

Decision-making on colorectal cancer screening in Curaçao - interviews with the target population.

BACKGROUND: During the first year of the population based colorectal cancer (CRC) screening program on Curaçao, about 20% of invitees participated. This study explored the target population's perceptions and awareness on CRC (screening), beliefs on the program provision, their preferences and information needs for informed decision-making. METHODS: Semi-structured interviews with 23 individuals, who were not yet invited for CRC screening, were recorded, transcribed, coded and analyzed. RESULTS: CRC (screening) was discussed in the context of personal health, where own responsibility and food were important. Cancer was perceived as an unpredictable disease that causes suffering and leads to death and was also associated with fear. Despite being aware of the program, most respondents were not familiar with the screening procedure. Provision of the screening program was regarded positively and as an opportunity to contribute to health improvement. This seemed related to the expressed trust in the Caribbean Prevention Center (program organizer). Respondents preferred to make independent decisions about CRC screening participation. A personal approach, visual aids and media were the preferred sources of information. CONCLUSION: The results of our interviews suggest that it may be beneficial to provide information on CRC screening in Curaçao within the context of personal health. While including sensitivity to fears and respect for the autonomy of the target population. Finally, electronic media maybe useful in supporting informed decision-making.

Return to Work and Associated Costs after Treatment for Dupuytren's Disease.

BACKGROUND: Return to work is potentially an important factor in assessing the success of treatment. However, little is known about the return to work after treatment for Dupuytren's contracture. Therefore, the primary aim of this study was to assess return to work after limited fasciectomy and percutaneous needle fasciotomy. METHODS: Patients who underwent either a limited fasciectomy or percutaneous needle fasciotomy were invited to complete a return-to-work questionnaire at 6 weeks, 3 months, 6 months, and 12 months postoperatively. Median time to return to work was assessed using inverted Kaplan-Meier curves, and hazard ratios were calculated with Cox regression models. Finally, a cost analysis was carried out using the human capital method to determine indirect costs associated with loss of productivity. RESULTS: The authors included 2698 patients in the study, of which 53 percent were employed at intake and included in the follow-up. After 1 year of follow-up, 90 percent of the patients had returned to work. Median time to return to work was 2 weeks after limited fasciectomy and within days after percutaneous needle fasciotomy. Furthermore, physically strenuous work, female sex, and higher age were associated with a longer time to return to work. Lost productivity per patient was estimated at €2614.43. CONCLUSIONS: The majority of patients returned to work after treatment for Dupuytren's disease. Return to work is much faster after percutaneous needle fasciotomy compared to limited fasciectomy. These findings can be used for more evidence-based preoperative counseling with patients with Dupuytren's disease.
