Objective: this article discusses comprehensive care as a guiding tenet of the Brazilian Unified Health System (SUS), outlining health care practices, especially nursing, and the relationships built by subjects in action by means of different knowledge.
Methods: this is a theoretical reflection that aims to propose dimensions of analysis (access to services, reception, links, lines of care, accountability, and responsiveness), with an emphasis on the dilemmas and challenges of nursing. The proposed dimensions analyze the production of care and its political and technical aspects.
Conclusion: care should be the focus of all health care work, bearing in mind that intervention for technological action of each profession goes beyond the core of isolated knowledge, as is the case of nursing, which is connected to other professional practices, and can peruse other territories that operate through relational technologies, entering into the world of the needs of users and families.

Background: Forecasting future public pharmaceutical expenditure is a challenge for healthcare payers, particularly owing to the unpredictability of new market introductions and their economic impact. No best-practice forecasting methods have been established so far. The literature distinguishes between the top-down approach, based on historical trends, and the bottom-up approach, using a combination of historical and horizon scanning data.

Introduction: The objective of this study is to compare the 5 year overall survival of patients with stage I-III colon cancer treated by laparoscopic colectomy versus open colectomy.
Methods: Using Mecklenburg-Western Pomerania Cancer Registry data from 2008 to 2018, we will emulate a phase III, multicenter, open-label, two-parallel-arm hypothetical target trial in adult patients with stage I-III colon cancer who received laparoscopic or open colectomy as an elective treatment. An inverse-probability weighted Royston‒Parmar parametric survival model (RPpsm) will be used to estimate the hazard ratio of laparoscopic versus open surgery after confounding factors are balanced between the two treatment arms.

Unlabelled: Most of the available tools to assess adherence to Mediterranean diet (MedDiet) were constructed for adults, having limited applicability to children and adolescents. The aim of this study is to validate a specific questionnaire to assess adherence to MedDiet in children aged 3 to 6 years (MED4CHILD questionnaire). The validation was performed in a baseline examination of a cohort of children who were recruited in schools in seven cities.
