Participants will have the opportunity to learn techniques for mindfulness that have been established to reduce stress and assist with pain management with a member of the research team. Patients will be offered to listen to audio recording of relaxation sessions. Each session contains a relaxation technique that the patient practices while listening to the recording. Then the technique is used the next as a baseline to introduce a new technique more advanced. For some patients who struggle with the techniques the program will be adapted. Patients will choose 2 or 3 techniques and work on them.

Cognitive prehabilitation will consist on the daily use of Lumosity training program, an already existing free app built to increase memory skills. The program proposed by Lumosity is tailored to each patient. The use of Lumosity will be monitored at each in-person session. Patients will be expected to complete at least three 5-minute sessions of Lumosity training per day.

Nutrition prehabilitation will involve transitioning the patient to the Mediterranean diet with targets regarding hydration and the proportion of fruits, vegetables, whole grains, and healthy fats the patient will consume in a given day. This nutritional program is flexible, and it allows for specific physician and nutritionist-recommended dietary needs to be incorporated. The patient is also given tools to encourage success in healthier eating, including recipes, sample menus, healthy restaurant options, meal kit options, and local CSA box options

Changes in physical status will be examined using 6 Min Walk Test. The evaluation should be based on differences between pre- and post prehabilitation performance.

Changes in physical status will be examined using Timed Up and Go Test. The evaluation should be based on differences between pre- and post prehabilitation performance.

Changes in physical status will be examined using Five Times Sit to Stand Test. The evaluation should be based on differences between pre- and post prehabilitation performance.

Changes in physical status will be examined using Wall Squat Test. The evaluation should be based on differences between pre- and post prehabilitation performance.

Body Mass Index will be recorded. The evaluation should be based on differences between pre- and post prehabilitation performance

Prevalence and global severity of anxiety will be evaluated using the APAIS (Amsterdam Preoperative Anxiety and Information Scale). The evaluation should be based on differences between pre- and post prehabilitation performance.

Prevalence and global severity of anxiety will be evaluated using the Pain Catastrophizing Scale. The evaluation should be based on differences between pre- and post prehabilitation performance.

Mediterranean Diet Score will be collected. The evaluation should be based on differences between pre- and post prehabilitation performance. A high intake of Mediterranean foods: cereals, legumes, fruit, vegetables, fish, Mon-unsaturated fatty acids to Saturated fatty acids (M/S) ratio, and wine were scored positive (1) and a high intake of the non-Mediterranean foods: dairy and meat negative (0). The score ranged from 0 to 9 and the higher the score the better the compliance to a traditional Mediterranean diet.

Cognitive functions will evaluated by the qMCI test. The evaluation should be based on differences between pre- and post prehabilitation performance.

Postoperative complications will be scored by the Comprehensive Complication Index. The Comprehensive Complication Index (CCI®) is based on the complication grading by Clavien-Dindo Classification and implements every occurred complication after an intervention. The overall morbidity is reflected on a scale from 0 (no complication) to 100 (death).

Pain scores will be assessed daily by the patient-reported Visual Analog Scale. Visual analog scale to assess the perceived stress on a horizontal, non-calibrated line of 10 cm, ranging from very low (0) to very high (10)

Cumulative opioid consumption will be obtained from the patients' charts up to 7 days after surgery or discharge from hospital if earlier.

Neuropathic pain will be measured by the Patient Reported Outcome Measurement Information System (PROMIS) Neuropathic Pain Quality scale (PROMIS-PQ-Neuro). The questionnaire contains 5 items questions. Scores are based on patient responses to questions about pain intensity. 0 indicates no pain; 5 indicates the most pain imaginable. The total score may be up to 25.

Hospital length of stay assessed from patients' medical administrative data in days

Quality of life evaluated thanks to the SF-36 scale is a 36-item patient-reported questionnaire that covers eight health domains: physical functioning (10 items), bodily pain (2 items), role limitations due to physical health problems (4 items), role limitations due to personal or emotional problems (4 items), emotional well-being (5 items), social functioning (2 items), energy/fatigue (4 items), and general health perceptions (5 items). Scores for each domain range from 0 to 100, with a higher score defining a more favorable health state. Results will be normalized on "baseline" (before prehab) scores.
