Impact of COVID-19 on patient experience of kidney care: a rapid review.

INTRODUCTION: In March 2020, a pandemic state was declared due to SARS-COV-2 (COVID-19). Patients with kidney disease, especially those on replacement therapies, proved more susceptible to severe infection. This rapid literature review aims to help understand how the pandemic impacted patient experience of kidney care. METHODS: It was conducted in accordance with Cochrane Rapid Review interim guidance. Search terms, 'coronavirus', 'kidney care', and 'patient-reported experience' and terms with similar semantic meaning, identified 1,117 articles in Medline, Scopus, and Worldwide Science. Seventeen were included in the narrative synthesis. RESULTS: The findings were summarised into three themes: remote consultation and telemedicine (n = 9); psychosocial impact (n = 2); and patient satisfaction and patient-reported experience (n = 6). Patients were mostly satisfied with remote consultations, describing them as convenient and allowing avoidance of hospital visits. Anxieties included missing potentially important clinical findings due to lack of physical examination, poor digital literacy, and technical difficulties. Psychosocial impact differed between treatment modalities-transplant recipients expressing feelings of instability and dread of having to return to dialysis, and generally, were less satisfied, citing reduced ability to work and difficulty accessing medications. Those on home dialysis treatments tended to feel safer. Findings focused on aspects of patient experience of kidney care during the pandemic rather than a holistic view. CONCLUSIONS: There was little direct evaluation of modality differences and limited consideration of health inequalities in care experiences. A fuller understanding of these issues would guide policy agendas to support patient experience during future public health crises.

Nutritional and Non-Nutritional Strategies in Bodybuilding: Impact on Kidney Function.

Bodybuilders routinely engage in many dietary and other practices purported to be harmful to kidney health. The development of acute kidney injury, focal segmental glomerular sclerosis (FSGS) and nephrocalcinosis may be particular risks. There is little evidence that high-protein diets and moderate creatine supplementation pose risks to individuals with normal kidney function though long-term high protein intake in those with underlying impairment of kidney function is inadvisable. The links between anabolic androgenic steroid use and FSGS are stronger, and there are undoubted dangers of nephrocalcinosis in those taking high doses of vitamins A, D and E. Dehydrating practices, including diuretic misuse, and NSAID use also carry potential risks. It is difficult to predict the effects of multiple practices carried out in concert. Investigations into subclinical kidney damage associated with these practices have rarely been undertaken. Future research is warranted to identify the clinical and subclinical harm associated with individual practices and combinations to enable appropriate and timely advice.

Quality of Life and Physical Function in Older Patients on Dialysis: A Comparison of Assisted Peritoneal Dialysis with Hemodialysis.

BACKGROUND AND OBJECTIVES: In-center hemodialysis (HD) is often the default dialysis modality for older patients. Few centers use assisted peritoneal dialysis (PD), which enables treatment at home. This observational study compared quality of life (QoL) and physical function between older patients on assisted PD and HD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Patients on assisted PD who were >60 years old and on dialysis for >3 months were recruited and matched to patients on HD (needing hospital transport) by age, sex, diabetes, dialysis vintage, ethnicity, and index of deprivation. Frailty was assessed using the Clinical Frailty Scale. QoL assessments included Hospital Anxiety and Depression Scale (HADS), Short Form-12, Palliative Outcomes Symptom Scale (renal), Illness Intrusiveness Rating Scale, and Renal Treatment Satisfaction Questionnaire (RTSQ). Physical function was evaluated by Barthel Score and timed up and go test. RESULTS: In total, 251 patients (129 PD and 122 HD) were recruited. In unadjusted analysis, patients on assisted PD had a higher prevalence of possible depression (HADS>8; PD=38.8%; HD=23.8%; P=0.05) and higher HADS depression score (median: PD=6; HD=5; P=0.05) but higher RTSQ scores (median: PD=55; HD=51; P<0.01). In a generalized linear regression model adjusting for age, sex, comorbidity, dialysis vintage, and frailty, assisted PD continued to be associated with higher RTSQ scores (P=0.04) but not with other QoL measures. CONCLUSIONS: There are no differences in measures of QoL and physical function between older patients on assisted PD and comparable patients on HD, except for treatment satisfaction, which is higher in patients on PD. Assisted PD should be considered as an alternative to HD for older patients, allowing them to make their preferred choices.

Conservative care for ESRD in the United Kingdom: a national survey.

BACKGROUND AND OBJECTIVES: Conservative kidney management (CKM) has been developed in the United Kingdom (UK) as an alternative to dialysis for older patients with stage 5 CKD (CKD5) and multiple comorbidities. This national survey sought to describe the current scale and pattern of delivery of conservative care in UK renal units and identify their priorities for its future development. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: A survey on practice patterns of CKM for patients age 75 and older with CKD5 was sent to clinical directors of all 71 adult renal units in the UK in March 2013. RESULTS: Sixty-seven units (94%) responded. All but one unit reported providing CKM for some patients. Terminology varied, although "conservative management" was the most frequently used term (46%). Lack of an agreed-upon definition of when a patient is receiving CKM made it difficult to obtain meaningful data on the numbers of such patients. Fifty-two percent provided the number of CKM patients age ≥ 75 years in 2012; the median was 45 per unit (interquartile range [IQR], 20-83). The median number of symptomatic CKM patients who would otherwise have started dialysis was eight (IQR, 4.5-22). CKM practice patterns varied: 35% had a written guideline, 23% had dedicated CKM clinics, 45% had dedicated staff, and 50% provided staff training on CKM. Most units (88%) provided primary care clinicians with information/advice regarding CKM. Eighty percent identified a need for better evidence comparing outcomes on CKM versus dialysis, and 65% considered it appropriate to enter patients into a randomized trial. CONCLUSIONS: CKM is provided in almost all UK renal units, but scale and organization vary widely. Lack of common terminology and definitions hinders the development and assessment of CKM. Many survey respondents expressed support for further research comparing outcomes with conservative care versus dialysis.

Predictors of recurrent hyperparathyroidism after total parathyroidectomy in chronic renal failure.

BACKGROUND/AIMS: Recurrent hyperparathyroidism (HPT) after total parathyroidectomy (TPTX) in chronic renal failure appears more common than might be anticipated. METHODS: To study its predictors, we reviewed all 20 cases of TPTX performed at our hospital in a 10-year period. RESULTS: During follow-up (median 46.8 months (range 9.3-120.3)), 15 patients had measurable PTH levels (>10 pg/ml), 7 had levels above the normal range (recurrent HPT), and 3 had PTH levels >300 pg/ml (severe recurrent HPT). Total follow-up post-TPTX was equal in those who developed recurrent HPT and others, but those with recurrent HPT had spent longer on dialysis post-TPTX (61.9 +/- 34.9 vs. 21.8 +/- 12.0 months; p = 0.001). Patients with recurrent HPT required less vitamin D supplementation during the 10 days post-TPTX (p = 0.025). Log [maximal PTH post-TPTX] correlated with duration of dialysis dependency post-TPTX (r = 0.591, p = 0.006), lowest serum calcium level during the first 30 days post-TPTX (r = 0.449, p = 0.047), and mean serum calcium during the first 30 days post-TPTX (r = 0.546, p = 0.013). Mean log [maximal PTH post-TPTX] was significantly lower in patients with ectopic calcification (p = 0.047). In multiple regression analysis, duration of dialysis post-TPTX and lowest serum calcium level during the first 30 days post-TPTX were the only independent predictors of log [maximal PTH post-TPTX]. CONCLUSION: Recurrent HPT is common following TPTX and predicted by duration of dialysis dependency post-TPTX, a measure of overall exposure to the uraemic stimulus to parathyroid hyperplasia, and the degree of early hypocalcaemia, possibly reflecting the adequacy of operative parathyroid ablation.

Stability and in vitro efficacy of antibiotic-heparin lock solutions potentially useful for treatment of central venous catheter-related sepsis.

OBJECTIVES: Increasing numbers of patients for whom infection is a major risk are dependent on central venous catheters. Antibiotic-anticoagulant locks may have a role in preventing or treating catheter-related infections. The aim of this study was to determine the in vitro stability and efficacy of antibiotic-heparin lock solutions. METHODS: Candidate antibiotics (amikacin, ciprofloxacin, flucloxacillin, gentamicin, linezolid, teicoplanin) were investigated in vitro, either individually or in combination, in solution with heparin. The solutions were initially tested for visual precipitation. The efficacy of stable solutions and taurolidine was then tested in a catheter model bioassay system against microorganisms commonly encountered in catheter-related septicaemia. RESULTS: In general, lower concentrations of heparin (
