Construal Level as a Novel Pathway for Affect Regulation and Cancer Control

The objective of the proposed research is to conduct a longitudinal experiment on the neurocognitive pathways and individual differences in high-level construal for affect regulation and smoking cessation. The population is adult smokers aged 25-55 who have tried and failed to quit multiple times and who are experiencing poverty. The primary endpoints are (a) the similarity in neural representation of high-level construal to one of two candidate pathways, (b) the presence of meaningful individual differences in the neural representation of high-level construal, and (c) as a secondary endpoint, the effect size of the high-level construal condition (relative to treatment-as-usual) on smoking as measured by cigarettes per day. Each of these endpoints corresponds to a specific null hypothesis. The null hypothesis for the first endpoint is that high-level construal is not significantly different in its neural representation from down-regulation of craving, which would suggest that high-level construal does not operate through distinct mechanisms from traditional treatments. The null hypothesis for the second endpoint is that the between-subjects variability in the neural representation of construal level does not significantly relate to relevant individual differences measures (e.g., traits, task behavior), which would suggest that individual differences are not meaningfully related to outcomes. Finally, the null hypothesis for the secondary endpoint is that the magnitude of the effect of high-level construal on smoking as measured by reductions in average cigarettes per day is not significantly greater than in TAU, which would suggest that the efficacy of the high-level construal condition is not significantly greater than a standard text-messaging intervention. The primary endpoints will be assessed at baseline and change from pre-to-post training (8 weeks).

Effect on Fatigue of Light (Lux) Therapy in Patients With Cancer

Fatigue is a symptom most commonly associated with the diagnosis of cancer. Fatigue often appears before the diagnosis of cancer, is increasing during treatment with chemotherapy and persists for years after treatment in more than 35% of patients. Fatigue is the earliest and most important symptom described by cancer patients. Its prevalence in cancer chemotherapy patients is between 70 and 100%. Fatigue is more common to cancer patients and to the general population or other types of patients. Typically described as a lack of energy associated with mental disorders, fatigue related to cancer can be extremely debilitating. The causes are many, mainly including the cancer itself, side effects due to treatment, sleeplessness due to pain, anxiety or depression. The cancer-related fatigue has a negative and significant direct impact on all aspects of the patient's quality of life, especially the physical, social and behavioral. Despite the availability of certain treatments and the advanced biomedical research, fatigue remains an inevitable consequence of cancer and its treatment. The therapeutic use of natural light in medicine dates back to the late nineteenth century. Its remarkable effect on the stimulation of the immune system and fight against infections caused the development of the first therapy techniques (also called luxthérapie) awarded in 1903 by the Nobel Prize in medicine and physiology. Light plays a fundamental role in the regulation of circadian rhythms and homeostatic. The mechanism of action passes through a path "non-visual" involving melanopsin ganglion cells located in the retina. Activation of the pineal gland (epiphysis) by melanopsin cells allows transduce information "shadow and light" in melatonin synthesis from serotonin. Today, the effectiveness of the therapy is well established for treating fatigue-related disorders such as chronic fatigue, seasonal depression or seasonal or non-certain sleep disorders and in which the melatonin metabolism is disturbed. Light therapy, by its mechanism of action, allows reprogramming "of the biological clock and improved synchronization of circadian rhythms.

Evaluation of ESMO Guidelines Applicability and Adherence in Cancer Pain Management in the Palliative Care Setting

Palliative care (PC) is focused on improving the Quality of Life (QoL) of patients living with a life-threatening illness. Each year, an estimated 40 million people need PC management in the world. In the European Union, it is estimated that about 4,5 million of people are in the need of PC every year, with about 40% affected by malignant neoplasia. Data from a recent systematic review of the literature report that the prevalence of pain is 66% (95% confidence interval 58-75) in cancer patients with advanced stages of the disease. In 52% of cases, pain was moderate or severe in intensity (NRS, Numeric Rating Scale ?4). Furthermore, in addition to the basic pain, having characteristics of continuity over time even in the presence of fluctuations in intensity, the presence of acute painful episodes must also be considered, which are defined with the term of Breakthrough Cancer Pain, (BTcP), whose prevalence is estimated between 21 and 59%. The positive impact on the quality of life of cancer patients of adhering to current guidelines has been amply demonstrated. Recently, new guidelines or recommendations produced by scientific societies have published, including the European Association of Palliative Care, the National Comprehensive Cancer Network and the European Society for Medical Oncology (ESMO). In clinical facilities directly involved in the treatment of pain in cancer patients, implementing the directives set out in the guidelines appears to be a correct objective for the appropriateness of treatments. Nevertheless, there are no studies in Europe that have evaluated the applicability and adherence to guidelines in the treatment of cancer pain in advanced cancer patients. The present study intends to collect detailed information on the characteristics of pain and the treatment in a population of cancer patients cared by a network of specialized palliative care centers in order to assess the applicability and adherence of the latest European guidelines published by ESMO in 2018 for the treatment of pain in the specific area.

Evaluation of Intravenous Lidocaine and Time to Regression of the Sensory Block After Spinal Anesthesia (ELSA Trial)

The use of intravenous lidocaine in continuous infusion in the perioperative period is associated with a reduction in postoperative pain scores, opioid use, incidence of nausea and vomiting, among other favorable outcomes. However, this therapeutic intervention has not yet been adequately evaluated by clinical trials when associated with regional anesthesia. The aim of this study is to evaluate whether the use of intravenous lidocaine in continuous infusion during spinal anesthesia with isobaric bupivacaine alters the time to regression of sensory block in patients undergoing surgical procedures for the treatment of bone and connective tissue tumor surgeries. This will be a triple-blind randomized trial. The sample size estimated was 66 patients. The study will include all patients who meet the pre-established inclusion and exclusion criteria, choose to participate, and agree with the Informed Consent Form. The main anesthetic technique will be spinal anesthesia with 13 mg of isobaric bupivacaine. Patients will be allocated in two groups in a blindly after randomization: Group S (lidocaine 0.75mg.kg-1 in bolus followed by infusion of saline solution) and Group L (lidocaine 1.5 mg.kg-1 followed by continuous infusion of lidocaine solution at 2 mg.kg-1.h-1). The primary outcome will be the time to T12 regression of the sensory block. Will also be evaluated: time to regression of the motor block, most rostral dermatome achieved by the sensory block, time to two-segment regression oh the sensory block, propofol dose in the operating room, postoperative pain score at rest, pain at movement score, quality of recovery, use of opioids in the postoperative period, nausea or vomiting, dizziness, shivering, arrhythmias, hypotension, urinary retention, and length of stay. The records will be assigned to the RedCap database. The data will be extracted without identification of the allocation groups for the R software and the groups will be revealed to the researcher after the end of the statistical analysis to write the summary of the results. The results will be submitted to scientific journals afterward.
