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.

Weight loss trend after bariatric surgery in a population of obese patients.

BACKGROUND AND AIMS: Bariatric Surgery (BS) is a therapeutic option in patients with severe obesity whose non-surgical techniques have failed. No work has previously explored trajectories of weight loss and how long this was maintained. Aim of study is to describe effect of BS and nutritional intervention on body weight trend in patients with obesity. METHODS: 792 patients who underwent BS from 1996 to 2021 were included. The Protocol provides Laparoscopic Sleeve Gastrectomy (LSG), Vertical Gastroplasty (VBG) and Roux-en-Y Gastric Bypass (GB). %Total Weight Loss (%TWL) and %Excess Weight Loss (%EWL) were evaluated in three cohort of patients. Cumulative incidence of clinical goal after surgery was calculated at two and five years after BS. RESULTS: At two years of follow-up, average %TWL and %EWL were 31.2% (95% CI = 29.0-33.4%) and 71% (95% CI = 65.4-76.5%) for VBG, 34.7% (95% CI = 33.8-35.6%) and 78.0% (95% CI = 75.9-89.1%) for GB and 33.8% (95% CI = 32.5-35.1%) and 68.8% (95% CI = 66.1-71.6%) for LSG. At two years from surgery the cumulative incidence of clinical goal was 70.7% (95% CI = 59.1-79.1%) for VBG, 86.4% (95% CI = 82.4-89.6%) for GB and 83.4% (95% CI = 76.0-87.1%) for LSG. At five years from surgery, average % TWL and % EWL were 22.5% (95% CI = 10.2-34.8%) and 58.2% (95% CI = 28.4-88.1%) for VBG, 31.8% (95% CI = 30.2-33.3%) and 70.8% (95% CI = 67.5-74.1%) for GB and 29.5% (95% CI = 26.2-32.8%) and 62.0% (95% CI = 53.4-70.6%) for LSG respectively. At five years after having reached clinical goal the share of people who were able to maintain their weight was 49.5% (95% CI = 30.8-79.6%) for VBG, 69.5% (95% CI = 58.3-82.8%) for GB and 55.9% (95% CI = 42.1-74.3%) for LSG. The median time of clinical goal maintaining was 4.8 years for VBG (95% CI lower limit = 4.1), 6.6 years for GB (95% CI lower limit = 6.2) and 5.3 years for LSG (95% CI lower limit = 4.8). CONCLUSIONS: Our work confirm effectiveness of BS in patients with obesity and show that who do not reach clinical goal within 2 years, hardly will reach it later and suggest necessity for a medium and long-term follow-up to prevent weight regain.

Predictive Role Of Body Composition Parameters In Operable Breast Cancer Patients Treated With Neoadjuvant Chemotherapy.

BACKGROUND: Fat tissue is strongly involved in BC tumorigenesis inducing insulin resistance, chronic inflammation and hormonal changes. Computed tomography (CT) imaging instead of body mass index (BMI) gives a reliable measure of skeletal muscle mass and body fat distribution. The impact of body composition parameters (BCPs) on chemosensitivity is still debated. We examined the associations between BCPs and tumor response to neoadjuvant chemotherapy (NC) in patients treated for operable breast cancer (BC). METHODS: A retrospective review of BC patients treated with NC in Modena Cancer Center between 2005 and 2017 was performed. BCPs, such as subcutaneous fat area (SFA), visceral fat area (VFA), lumbar skeletal muscle index (LSMI) and liver-to-spleen (L/S) ratio were calculated by Advance workstation (General Electric), software ADW server 3.2 or 4.7. BMI and BCPs were correlated with pathological complete response (pCR) and survival outcomes. RESULTS: 407 patients were included in the study: 55% with BMI < 25 and 45% with BMI ≥ 25. 137 of them had pre-treatment CT scan imagines. Overweight was significantly associated with postmenopausal status and older age. Hormonal receptor positive BC was more frequent in overweight patients (p<0.05). Postmenopausal women had higher VFA, fatty liver disease and obesity compared to premenopausal patients. No association between BMI classes and tumor response was detected. High VFA and liver steatosis were negative predictive factors for pCR (pCR rate: 36% normal VFA vs 20% high VFA, p= 0.048; no steatosis 32% vs steatosis 13%, p=0.056). Neither BMI classes nor BCPs significantly influenced overall survival and relapse-free survival. CONCLUSION: Visceral adiposity as well as steatosis were closely involved in chemosensitivity in BC patients treated with NC. Their measures from clinically acquired CT scans provide significant predictive information that outperform BMI value. More research is required to evaluate the relationship among adiposity site and survival outcomes.
