    Abstract Gadolinium-based contrast media (GBCM) toxicity in patients with kidney disease is a concern for the possible development of systemic nephrogenic fibrosis and possible renal complications. This review focuses on the pathological mechanisms underlying the potential kidney toxicity of gadolinium. Gadolinium, as a free compound (Gd3+), is highly toxic in humans because it competes with divalent calcium (Ca2+) and magnesium (Mg2+) ions, interfering in some relevant biologic processes. Its toxicity is blunted by the complexing of Gd3+ with a carrier, allowing its use in magnetic resonance imaging. The binding reaction between gadolinium and a carrier is thermodynamically reversible. Consequently, under some conditions, gadolinium can be released in the interstitial space as a free Gd3+ compound with the possibility of toxicity. Other metals such as iron, copper, and calcium can interfere with the binding between gadolinium and its carrier because they compete for the same binding site. This process is known as transmetallation. In patients with kidney impairment, conditions such as low clearance of the Gd-carrier complex, acid-base derangements, and high serum phosphorous can increase the presence of free Gd3+, leading to a higher risk for toxicity.

    Abstract The COronaVIrus Disease 19 (COVID-19) pandemic is an emerging reality in nephrology. In a continuously changing scenario, we need to assess our patients' additional risk in terms of attending hemodialysis treatments, follow-up peritoneal dialysis, and kidney transplant visits. The prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-20 infection in the general population plays a pivotal role in estimating the additional COVID-19 risk in chronic kidney disease (CKD) patients. Unfortunately, local prevalence is often obscure, and when we have an estimation, we neglect the number of asymptomatic subjects in the same area and, consequently, the risk of infection in CKD patients. Furthermore, we still have the problem of managing COVID-19 diagnosis and the test's accuracy. Currently, the gold standard for SARS-CoV-2 detection is a real-time reverse transcription-polymerase chain reaction (rRT-PCR) on respiratory tract samples. rRT-PCR presents some vulnerability related to pre-analytic and analytic problems and could impact strongly on its diagnostic accuracy. Specifically, the operative proceedings to obtain the samples and the different types of diagnostic assay could affect the results of the test. In this scenario, knowing the local prevalence and the local screening test accuracy helps the clinician to perform preventive measures to limit the diffusion of COVID-19 in the CKD population.

    Abstract Purpose: Follow-up of automated peritoneal dialysis (APD) has been improved by data transmission by cellular modem and internet cloud. With the new remote patient monitoring (RPM) technology, clinical control and prescription of dialysis are performed by software (Baxter Claria-Sharesource), which allows the center to access home operational data. The objective of this pilot study was to determine the impact of RPM compared to traditional technology, in clinical, organizational, social, and economic terms in a single center.
    Methods: We studied 21 prevalent APD patients aged 69 ± 13 years, on dialysis for a median of 9 months, for a period of 6 months with the traditional technology and 6 months with the new technology. A relevant portion of patients lived in mountainous or hilly areas.
    Results: Our study shows more proactive calls from the center to patients after the consultation of RPM software, reduction of calls from patients and caregivers, early detection of clinical problems, a significant reduction of unscheduled visits, and a not significant reduction of hospitalizations. The analysis also highlighted how the RPM system lead to relevant economic savings, which for the health system have been calculated € 335 (mean per patient-month). With the social costs represented by the waste of time of the patient and the caregiver, we calculated € 685 (mean per patient-month).
    Conclusion: In our pilot report, the RPM system allowed the accurate assessment of daily APD sessions to suggest significative organizational and economic advantages, and both patients and healthcare providers reported good subjective experiences in terms of safety and quality of follow-up.

    Abstract Maximal oxygen consumption (V̇O₂ₘₐₓ) is impaired in heart (HTx), kidney (KTx), and liver (LTx) transplanted recipients and the contribution of the cardiovascular, central, and peripheral (muscular) factors in affecting V̇O₂ₘₐₓ improvement after endurance training (ET) has never been quantified in these patients. ET protocols involving single leg cycling (SL) elicit larger improvements of the peripheral factors affecting O₂ diffusion and utilization than the double leg (DL) cycling ET. Therefore, this study aimed to compare the effects of SL-ET vs DL-ET on V̇O₂ₘₐₓ. We determined the DL-V̇O₂ₘₐₓ and maximal cardiac output before and after 24 SL-ET vs DL-ET sessions on 33 patients (HTx = 13, KTx = 11 and LTx = 9). The DL-V̇O₂ₘₐₓ increased by 13.8% ± 8.7 (p < 0.001) following the SL-ET, due to a larger maximal O₂ systemic extraction; meanwhile, V̇O₂ₘₐₓ in DL-ET increased by 18.6% ± 12.7 (p < 0.001) because of concomitant central and peripheral adaptations. We speculate that in transplanted recipients, SL-ET is as effective as DL-ET to improve V̇O₂ₘₐₓ and that the impaired peripheral O₂ extraction and/or utilization play an important role in limiting V̇O₂ₘₐₓ in these types of patients. Novelty: SL-ET increases V̇O₂ₘₐₓ in transplanted recipients because of improved peripheral O₂ extraction and/or utilization. SL-ET is as successful as DL-ET to improve the cardiorespiratory fitness in transplanted recipients. The model of V̇O₂ₘₐₓ limitation indicates the peripheral factors as a remarkable limitation to the V̇O₂ₘₐₓ in these patients.

    Abstract Purpose: We performed a pilot study to evaluate the feasibility of future research about the presence of subclinical kidney damage after Gadolinium-based contrast media exposure. The future study aims to understand which are the behaviors of two markers of kidney damage, such as urinary NephroCheck (NC) and/or neutrophil gelatinase-associated lipocalin (NGAL). Specifically, after GBCM exposure, NC urinary detection should identify proximal tubule damage while NGAL urinary detection should be related to distal tubule damage.
    Methods: We performed a pilot study in patients who had Gadolinium exposure. The feasibility of future study is reached when at least 90% of candidates completed the pilot study. In each patient, we tested urinary NC and NGAL levels 24 h before magnetic resonance imaging (MRI) and 12-24 h after the exposure. Furthermore, we evaluated the administration of other nephrotoxic agents, the presence of comorbidity, and kidney function by S-creatinine and urine protein before the MRI.
    Results: We enrolled 35 candidates of whom 33 patients completed all study procedures. Our population had a mean age of 60.7 ± 14.8 years with normal kidney function with a median S-creatinine equal to 0.7 mg/dl (Interquartile range [IQR] 0.6-0.91). Urinary NC levels increased from 0.21 ng
    Conclusion: Our pilot study seems adequate in terms of feasibility and encourages us to focus our future research on renal proximal tubule, as the principal site of subclinical kidney damage after Gadolinium exposure.

    Abstract The follow-up automated peritoneal dialysis (APD) patients has been recently improved as data can be transmitted remotely to an internet cloud. The introduction of remote patient monitoring (RPM) technologies also allows a better clinical control and tailoring of dialysis treatment through a web-based software (Claria-Sharesource Baxter). The aim of the present study is to determine the impact of RPM in a single center, both in clinical and organizational terms, compared to traditional technologies. We studied 26 prevalent APD patients aged 69±13 years, observing them for a period of six months while using the traditional technology and then further six months using the new technology. The patients had been on dialysis for 9 months before the start of the study and a relevant portion of them lived in mountainous or hilly areas. Our study shows an increase in the number of proactive calls from the center to the patients, a reduction of anxiety in patients and caregivers, an earlier detection of clinical problems, a reduction of unscheduled (urgent) visits and finally a reduction of hospitalizations after the adoption of RPM software. In our experience, the RPM system showed a good performance and a simple interface, allowing for the precise assessment of daily APD. Furthermore, RPM system improved the interaction between patients and healthcare providers, with a significant benefit in terms of safety and of care quality.
