RESUMO

Background: Measuring cell-free (cf)DNA in blood and tissues holds significant potential as a minimally invasive method for disease monitoring in cancer. Cancers arising in the oropharynx and causally linked to human papillomavirus (HPV) represent an ideal model in which to interrogate these methods. Patients and methods: We designed an ultrasensitive and quantitative droplet digital (dd)PCR assay to detect the five dominant high-risk HPV subtypes linked to oropharyngeal cancer (OPC). We enrolled a pilot observational cohort of 22 patients with advanced HPV+ OPC to evaluate the clinical utility of our assay and explore its predictive and prognostic potential. Results: Total tumor burden (TTB) strongly correlated with HPV cfDNA levels (R = 0.91, P = 2.3×10-6) at this cohort size, and in most cases more distant anatomic disease locations predicted increasing HPV cfDNA levels. All participants demonstrated a corresponding change in their HPV cfDNA levels at a median of 16 days (range 12-38) before restaging scans confirming treatment response or progression. Patients with locoregional disease in the head and neck or pulmonary-only metastases had worse outcomes (P = 0.01). Both TTB and median plasma HPV cfDNA levels negatively correlated with survival (R=-0.65, P = 0.01; R=-0.48, P = 0.05, respectively). Conclusion(s): Plasma HPV cfDNA monitoring recapitulates fluctuations in disease status. While blood-based HPV DNA monitoring does not currently have a role in managing HPV+ OPC, these data speak to their broad clinical potential in an era of precision medicine.

RESUMO

BACKGROUND: One of the key elements to enhance the uptake of evidence in public health policies is stimulating cross-sector collaboration. An intervention stimulating collaboration is a policy game. The aim of this study was to describe the design and methods of the development process of the policy game 'In2Action' within a real-life setting of public health policymaking networks in the Netherlands, Denmark and Romania. METHODS: The development of the policy game intervention consisted of three phases, pre intervention, designing the game intervention and tailoring the intervention. RESULTS: In2Action was developed as a role-play game of one day, with main focus to develop in collaboration a cross-sector implementation plan based on the approved strategic local public health policy. CONCLUSIONS: This study introduced an innovative intervention for public health policymaking. It described the design and development of the generic frame of the In2Action game focusing on enhancing collaboration in local public health policymaking networks. By keeping the game generic, it became suitable for each of the three country cases with only minor changes. The generic frame of the game is expected to be generalizable for other European countries to stimulate interaction and collaboration in the policy process.

RESUMO

BACKGROUND AND AIM: A high intake of dairy has been linked to lower risk of type 2 diabetes (T2D). The relationship between dairy intake and glucose metabolism is still not well understood. The aim of this study was to investigate the relation between the intake of total dairy and dairy subgroups and T2D and measures of glucose metabolism. METHODS AND RESULTS: A total of 5953 Danish men and women aged 30-60 years without baseline diabetes or cardiovascular diseases were included in this prospective analysis. The dairy intake at baseline was categorised into low-fat dairy, full-fat dairy, milk and milk products, cheese and fermented dairy. Fasting plasma glucose (FPG), 2-h plasma glucose (2hPG), HbA1c, insulin resistance (HOMA2-IR) and beta-cell function (HOMA2-B) were considered at 5-year follow-up. In the maximally-adjusted model (demographics, lifestyle factors, dietary factors and waist), cheese intake was inversely associated with 2hPG (ß = -0.048, 95% CI -0.095; -0.001). Fermented dairy intake was inversely associated with FPG (ß = -0.028, 95% CI -0.048; -0.008) and HbA1c (ß = -0.016, 95% CI -0.030; -0.001). Total dairy intake and the dairy subgroups were not related to HOMA-IR and HOMA-B in the maximally-adjusted model. Furthermore, there was no significant association between intake of total dairy or any of the dairy subgroups and incidence of T2D. CONCLUSION: Our data suggest a modest beneficial effect of cheese and fermented dairy on glucose regulation measures; however, this did not translate into a significant association with incident T2D.
