Objectives: To estimate how many people object to storage of biological samples collected in health care in Sweden and to their use in research and how many withdraw previous consent.
Design: Cross sectional study of register data.
Setting: Biobanks used in Swedish health care, 2005-6. Population Data on refusal to consent were obtained for 1.4 million biobank samples per year from 20 of 21 counties.
Main Outcome Measures: Rates of preliminary refusal to consent, confirmed refusal, and withdrawal of consent.
Results: Patients refused consent to either storage or use of their samples in about 1 in 690 cases; about 1 in 1600 confirmed their decision by completing a dissent form. Rather than having the samples destroyed, about 1 in 6200 patients wanted to restrict their use. Of those who had previously consented, about 1 in 19,000 withdrew their consent.
Conclusions: Refusal to consent to biobank research in Sweden is rare, and the interests of individuals and research interests need not be at odds. The Swedish healthcare organisation is currently obliged to obtain either consent or refusal to each potential use of each sample taken, and lack of consent to research is used as the default position. A system of presumed consent with straightforward opt out would correspond with people's attitudes, as expressed in their actions, towards biobank research.

Background: Screening for breast cancer has been effective in decreasing mortality. Mammography is not readily available in resource-limited countries like India. Annual clinical breast examination has been demonstrated to be as effective as biennial mammography in reducing mortality with much less cost.

Background And Aim: Managing obesity requires a comprehensive approach that involves therapeutic lifestyle changes, medications, or metabolic surgery. Many patients seek health information from online sources and artificial intelligence models like ChatGPT, Google Gemini, and Microsoft Copilot before consulting health professionals. This study aims to evaluate the appropriateness of the responses of Google Gemini and Microsoft Copilot to questions on pharmacologic and surgical management of obesity and assess for bias in their responses to either the ADA or AACE guidelines.

The relationship between nanoliposomal irinotecan/fluorouracil/leucovorin (NFF) treatment outcomes and neutropenia in patients with pancreatic cancer has not been thoroughly examined. Thus, we conducted a retrospective analysis of data from patients with pancreatic cancer who were treated with NFF to investigate this relationship. Neutropenia was assessed according to the Common Terminology Criteria for Adverse Events across three cutoffs: A (grade 0 versus grade 1-4), B (grades 0-1 versus 2-4), and C (grades 0-2 versus 3-4).

Methods: We conducted a single-center, retrospective cohort study of French older adults. Participants with Mini-Mental State Examination (MMSE) ≥ 24 were recruited from a fall clinic in a geriatrics department. We recorded history of falls in the preceding 6 months, as well as Timed Up and Go test and mobility assessment at baseline and at 6- and 12-month follow-up.

Introduction: Informed consent documents (ICDs) are integral to a research project and must provide all required information to the participant. We undertook a 6-year retrospective cross-sectional analysis of ICDs to assess the same.
Methods: We accessed 300 ICDs from studies submitted to institutional ethics committee.
