Combining telemedicine and in-person visits to deliver care to patients with severe chronic kidney disease (CKD): Lessons learned from COVID-19.

BACKGROUND: Telemedicine has been widely used to deliver healthcare to outpatients during the COVID-19 pandemic. The effectiveness of this modality is unclear in patients with a pre-dialysis stage of chronic kidney disease (CKD). This study aims to describe the clinical characteristics and management of CKD patients receiving telemedicine care during the COVID-19 pandemic. MATERIALS AND METHODS: A retrospective single-center cohort study enrolled outpatients with pre-dialytic stage of CKD from March 9 to June 21, 2020. Telemedicine was proposed for all patients with a stable CKD to reduce the risk of in-hospital transmission whereas in-person visit was performed for patients requiring urgent evaluation. RESULTS: In a 15-week period, 97 patients received 116 nephrological visits. According to the modality of healthcare delivery, the patients were subdivided into telemedicine (66%) and in-person visit (34%) groups. Mean age of all CKD patients was 72.8 ± 12.5 years and males were 50.5% of the population. The average estimated glomerular filtration rate (eGFR) was 14.6 ± 6 mL/min. Patients evaluated by telemedicine had better kidney function (GFR, 16.2 ± 6.4 vs. 13.6 ± 5.9 mL/min/1.73m2; p = 0.037), a lower body mass index (BMI) (24.1 ± 1.7 vs. 30.6 ± 5.7; p = 0.019), and a lower risk of CKD progression (51.1 vs. 25.4%, p = 0.017) than patients requiring in-person visit. Telemedicine-visit patients experienced a significantly lower number of pharmacological changes than patients managed in the ambulatory setting. Telemedicine was also used to conduct 20% of educational meetings on the choice of dialysis modality and 18.9% of pre-eligibility visits for kidney transplantation. CONCLUSION: Telemedicine made it possible to provide care to and maintain close monitoring of 2/3 of patients with pre-dialytic stage of CKD during the COVID-19 pandemic.

Sleep and Prospective Memory: A Retrospective Study in Different Clinical Populations.

Prospective memory (PM) is essential in everyday life because it concerns the ability to remember to perform an intended action in the future. This ability could be influenced by poor sleep quality, the role of which, however, is still being debated. To examine the role of sleep quality in PM in depth, we decided to perform a retrospective naturalistic study examining different clinical populations with a primary sleep disorder or comorbid low sleep quality. If sleep is important for PM function, we could expect poor sleep to affect PM performance tasks both directly and indirectly. We examined a total of 3600 nights, recorded using actigraphy in participants belonging to the following groups: primary insomnia (731 nights); narcolepsy type 1 (1069 nights); attention deficit hyperactivity disorder (152 nights in children and 239 in adults); severe obesity (232 nights); essential hypertension (226 nights); menopause (143 nights); healthy controls (808 nights). In a naturalistic activity-based PM task, each participant originally wore an actigraph around the non-dominant wrist and was requested to push the event-marker button at two specific times of day: bedtime (activity 1) and get-up time (activity 2). Each clinical group showed significantly lower sleep quality in comparison to the control group. However, only narcolepsy type 1 patients presented a significantly impaired PM performance at get-up time, remembering to push the event-marker button around half the time compared not only to healthy controls but also to the other clinical groups. Overall, the present results seem to point to sleep quality having no effect on the efficiency of a naturalistic activity-based PM task. Moreover, the data indicated that narcolepsy type 1 patients may show a disease-specific cognitive deficit of PM.

Eating Behavior after Bariatric Surgery (EBBS) Questionnaire: a New Validated Tool to Quantify the Patients' Compliance to Post-Bariatric Dietary and Lifestyle Suggestions.

PURPOSE: In the management of bariatric surgery follow-up, a multidisciplinary approach allows to evaluate the weight loss maintenance and the dietary and lifestyle changes adherence. The main aim of this study is to create and to validate a questionnaire (eating behavior after bariatric surgery (EBBS)) to objectivize the compliance to dietary/lifestyle suggestions after bariatric surgery. MATERIALS AND METHODS: An observational retrospective monocentric clinical trial was carried out at the Bariatric Surgery Unit of Modena, Italy. All weight-related data of bariatric surgery patients collected during the multidisciplinary post-surgical path were recorded. EBBS questionnaire and three validated psychological tests were administered. EBBS includes 11 questions concerning food (domain A), drinks (B), behaviors (C), and lifestyle (S). All data analyzed in the study were collected during the same visit. RESULTS: In 41 enrolled patients (52.2 + 11.9 years), the total weight loss after surgery was 44.87 + 18.37 kg (- 35.40 + 11.60%), with a weight loss maintenance of 86.92 + 14.30%. The EBBS questionnaire showed a good internal validity (Cronbach's alpha 0.743, Hotelling's T-square test p < 0.001). The S domain was directly related with the percentage of weight loss maintained (p = 0.048), suggesting that the frequent physical activity and the periodic weight self-check are the most predictive behaviors to obtain weight control. None of the psychological questionnaires appeared related to the weight trend. CONCLUSIONS: We validated for the first time a 11-item self-filling questionnaire allowing to quantify the adaption to dietary/lifestyle suggestions provided after bariatric surgery. EBBS questionnaire could be a useful tool both in clinical and research setting to monitor the patient's adherence to post-surgical indications and to identify predictive factors for bariatric surgery efficacy.
