Survey and Questionnaire

Despite high success rates of hip and knee arthroplasty, up to 20% of patients report moderate-to-severe pain (NRS \> 3) persisting beyond the expected healing period. This investigator-initiated, descriptive cohort study will re-invite approximately 100 consenting patients with persistent postoperative pain-identified from a pool of \~7 000 respondents-to complete standardized assessments of neuropathic (DN4), nociplastic (IASP criteria + Fibromyalgia Survey Questionnaire) and nociceptive (KOOS/HOOS pain domains) pain. Primary outcomes are the prevalence of potential nociplastic pain and the proportion experiencing significant pain in two or more mechanistic categories. Secondary analyses will compare baseline vs. re-evaluated DN4 scores, FSQ and KOOS/HOOS distributions, and examine differences between patients with and without possible neuropathic pain. Findings will inform targeted pre- and postoperative pain management strategies.

The goal of this low-risk interventional study is to analyze participants' assessment of colorectal cancer screening program through screening method preference and experience after FOBT analysis in screaned participant population for colorectal cancer; could include any of the following: both sexes, age 50-69 years, asympthomatic volunteers. The main aims to answer are: * Values of experience of participants into screening programme. * Values of preferences of participants for screening methods. Participants will answer two questionnaires and they'll be given their information and clinical data to investigator or health personnel.

The objective of this low-risk interventional study is to evaluate whether the PreveCol® test has sufficient efficiency to be considered as a second-line method for the detection of both colorectal cancer and advanced adenomas when used prospectively in the screening population with a previous positive FOBT result, which could include any of the following: both sexes, age 50-69 years, asympthomatic volunteers. The main aims to be answered are: * Values of efficacy, efficiency, impact and safety of PreveCol. * Values of preferences of participants for screening methods. * Values of PREMs into screening programme. Participants will provide a blood sample prior to a screening colonoscopy, and complete two questionnaires. They will give their sample, information and clinical data to the investigator or health care personnel.

The World Health Organization (WHO) defines digital health as the field of knowledge and application related to any aspect of the adoption of digital technology in the stages of improvement. The combination of digital health with technology brings about a new transformation in digital media. This transformation allows for the development of communication and information in health services, the ability to conduct health-related research on digital media and the evaluation of this data. The ease of access to information and the provision of a timely feedback mechanism in the face of problems have enabled the spread of digital health systems, and have also enabled chronic disease management and epidemic disease monitoring. It is recommended that the term digital readiness be used to cover the combination of digital access and use, digital literacy and digital health literacy. Digital health readiness is also defined as the main determinant of health and is thought to contribute to the improvement of health processes with the development of digital health literacy and to be a useful solution against health problems that may arise in the follow-up of chronic diseases. Although there are tools in the literature that evaluate digital health readiness, there is no Turkish assessment tool that facilitates the follow-up of non-communicable chronic diseases. Therefore, the aim of our study is to evaluate the translation, validity, and reliability of the Digital Health Readiness Questionaire into Turkish in individuals with chronic non-infectious diseases.
