RESUMO
Healthcare delivery has become more complicated, particularly with the addition of digital tools and advanced technologies that can further exacerbate existing disparities. New approaches to solve complex, multi-faceted problems are needed. Human-centered design (HCD), also known as design thinking, is an innovative set of methods to develop solutions to these types of issues using collaborative, team-based, and empathetic approaches focused on end user experiences. Originally advanced in technology sectors, HCD has garnered growing attention in quality improvement, healthcare redesign, and public health and medical education. During the COVID-19 pandemic, our healthcare organization recognized notable differences in utilization of virtual (video-based) services among specific patient populations. In response, we mobilized, and using HCD, we collectively brainstormed ideas, rapidly developed prototypes, and iteratively adapted solutions to work toward addressing this digital divide and clinic and systems-level struggles with improving and maintaining digital health access. HCD approaches create a cohesive team-based structure that permits the dismantling of organizational hierarchies and departmental silos. Here we share lessons learned on implementing HCD into clinical care settings and how HCD can result in the development of site-specific, patient-centered innovations to address access disparities and to improve digital health equity.

Background and Objectives: Anaerobic bacteria like Fusobacterium can lead to severe and life-threatening infections. The inherent complexities in the isolation of these bacteria may result in diagnostic and therapeutic delays, thereby escalating both morbidity and mortality rates. We aimed to examine data from patients with infections due to Fusobacterium to gain insights into the epidemiology and clinical outcomes of patients with these infections. Methods and Results: We conducted a retrospective analysis of clinical data from a cohort of patients with cultures positive for Fusobacterium species at a tertiary care medical center in the United States. Between 2009 and 2015, we identified 96 patients with cultures positive for Fusobacterium. Patients could be categorized into three groups based on the site of primary infection. Patients with head and neck infections constituted 37% (n 36). Patients with infections of other soft tissue sites accounted for 38.5% (n 37). Patients with anaerobic bacteremia due to Fusobacterium formed 24% (n 23) of the cohort. Surgical intervention coupled with antibiotic therapy emerged as cornerstones of management for patients with head and neck or other soft tissue infections, who generally exhibited more favorable outcomes. Patients with bacteremia were older, more likely to have malignancy, and had a high mortality rate. When speciation was available, Fusobacterium necrophorum was the most frequently isolated species. Conclusions: Our retrospective analysis of epidemiology and clinical outcomes of Fusobacterium infections revealed three distinct cohorts. Patients with head, neck, or soft tissue infections had better outcomes than those with bacteremia. Our findings highlight the importance of employing management strategies based on infection site and underlying comorbidities in patients with Fusobacterium infections. Further research is needed to investigate the optimal therapeutic strategies and identify prognostic indicators to improve clinical outcomes for these complex infections.

The COVID-19 pandemic has had lingering effects in healthcare. During the pandemic, inpatient bed shortages became a major barrier to providing care, and access to outpatient dialysis was delayed due to a shortage of staff. This resulted in lengthy admissions to the hospital while awaiting outpatient dialysis placement in a time when hospital bedspace was a scarce resource. In this report we describe the use of the Hospital at Home program for inpatient dialysis care as a novel method to both provide high quality patient care at home and also open inpatient beds in the hospital. Here, we present two cases where this program served both the needs of the patient and the hospital system by providing dialysis care to patients participating in the Hospital at Home program. One was a patient with a recent kidney transplant awaiting improvement in kidney function following transplant. The other was a new mother who was diagnosed with atypical hemolytic uremic syndrome and was awaiting recovery from her acute kidney injury after receiving complement inhibitor therapy. This program has been functional for the past 13 months and has served 37 patients and saved 1,007 inpatient days during that period. Each inpatient day provided by Hospital at Home represents bed space that was made available to another patient in need.

Purpose: The increasing incidence of nephrolithiasis underscores the need for effective, accessible tools to aid urologists in preventing recurrence. Despite dietary modification's crucial role in prevention, targeted dietary counseling using 24-hour urine collections is underutilized. This study evaluates ChatGPT-4, a multimodal large language model, in analyzing urine collection results and providing custom dietary advice, exploring the potential for artificial intelligence-assisted analysis and counseling. Materials and Methods: Eleven unique prompts with synthesized 24-hour urine collection results were submitted to ChatGPT-4. The model was instructed to provide five dietary recommendations in response to the results. One prompt contained all "normal" values, with subsequent prompts introducing one abnormality each. Generated responses were assessed for accuracy, completeness, and appropriateness by two urologists, a nephrologist, and a clinical dietitian. Results: ChatGPT-4 achieved average scores of 5.2/6 for accuracy, 2.4/3 for completeness, and 2.6/3 for appropriateness. It correctly identified all "normal" values but had difficulty consistently detecting abnormalities and formulating appropriate recommendations. The model performed particularly poorly in response to calcium and citrate abnormalities and failed to address 3/10 abnormalities entirely. Conclusions: ChatGPT-4 exhibits potential in the dietary management of nephrolithiasis but requires further refinement for dependable performance. The model demonstrated the ability to generate personalized recommendations that were often accurate and complete but displayed inconsistencies in identifying and addressing urine abnormalities. Despite these limitations, with precise prompt design, physician oversight, and continued training, ChatGPT-4 can serve as a foundation for personalized medicine while also reducing administrative burden, indicating its promising role in improving the management of conditions such as nephrolithiasis.

Managing sepsis and fluid resuscitation in patients with chronic kidney disease or end-stage renal disease is challenging for health care providers. Nurses are essential for early identification and treatment of these patients. Nurse education on assessing perfusion and implementing 3-hour bundled care can improve mortality rates in patients with sepsis. In this scoping review, initial screening identified 1176 articles published from 2015 through 2023 in the National Library of Medicine database; 29 articles were included in the literature summary and evidence synthesis. A systematic review meta-analysis was not possible because of data heterogeneity. The review revealed that most patients with chronic kidney disease or end-stage renal disease received more conservative resuscitation than did the general population, most likely because of concerns about volume overload. However, patients with chronic kidney disease or end-stage renal disease could tolerate the standard initial fluid resuscitation bolus of 30 mL/kg for sepsis. Outcomes in patients with chronic kidney disease or end-stage renal disease were similar to outcomes in patients without those conditions, whether they received standard or conservative fluid resuscitation. Patients who received the standard (higher) fluid resuscitation volume did not have increased rates of complications such as longer duration of mechanical ventilation, increased mortality, or prolonged length of stay. Using fluid responsiveness to guide resuscitation was associated with improved outcomes. The standard initial fluid resuscitation bolus of 30 mL/kg may be safe for patients with chronic kidney disease or end-stage renal disease and sepsis. Fluid responsiveness could be a valuable resuscitation criterion, promoting better decision-making by multidisciplinary teams. Further research is required.

Introduction: Neural epidermal growth factor like 1 membranous nephropathy (NELL1 MN) is associated with various secondary etiologies. However, previous studies on the frequency of these associations and their impact on outcomes are limited. We report a large multiinstitutional series of patients with NELL1 MN with a focus on secondary associations, pathology findings, and their impact on outcome. Methods: We retrospectively reviewed clinicopathologic features of NELL1 MN from 3 institutions and analyzed clinical and histologic associations with outcome. Results: Of 70 patients, 53% were male with a median age of 66 years; median proteinuria was 5.9 g/d. NELL1 MN was associated with lipoic acid (36%), heavy nonsteroidal antiinflammatory drug (NSAID) use (27%), autoimmune disease (23%), malignancy (10% recent, 23% any), mercury exposure (1%), and 11% had no known secondary association. At median follow-up of 11 months, 72% achieved complete or partial remission. Remission rate was 91% in patients with lipoic acid-associated NELL1 MN and ≥6 months of follow-up. On multivariable analyses, patients with primary NELL1 MN (adjusted odds ratio [OR]: 19.7, P = 0.01) and increasing degree of tubular atrophy and interstitial fibrosis (IFTA) (adjusted OR 1.1, P = 0.01) were less likely to achieve any remission, whereas complete remission (CR) was associated with lipoic acid use (adjusted OR: 10.9, P = 0.04, 95% confidence interval [CI]: 1.2-100) and lesser degrees of IFTA (adjusted OR: 0.79, P = 0.16, 95% CI: 0.66-0.96). Conclusion: Our findings strengthen the association between lipoic acid and NELL1 MN. Furthermore, our findings suggest that discontinuation of lipoic acid without immunosuppression should be considered as the first-line treatment.
RESUMO
Introduction: Causes of secondary oxalate nephropathy include enteric dysfunction and excessive intake of oxalate or oxalate precursors. During the COVID-19 pandemic, there has been a dramatic rise in sales of supplements and vitamin C, during which time we observed an apparent increase in the proportion of ingestion-associated oxalate nephropathy. Methods: We retrospectively reviewed secondary oxalate nephropathy and compared pre-pandemic (2018-2019) and pandemic (2020-early 2022) time periods. Results: We identified 35 patients with kidney biopsy proven (30 native, 5 allograft) oxalate nephropathy at a single academic institution. Supplement-associated oxalate nephropathy comprised a significantly higher proportion of cases during COVID-19 pandemic compared with the preceding 2 years (44% vs. 0%, P = 0.002), and was associated with use of vitamin C, dietary changes, and supplements. Oxalate nephropathy in the kidney allograft, in contrast, remained associated with enteric hyperoxaluria, antibiotic use, and dehydration. Many patients had diabetes mellitus (57%), hypertension (40%) and/or pre-existing chronic kidney disease (CKD, 49%). Of 9 patients in which the potentially causative ingestion was identified and removed, 8 experienced improvement in kidney function. Conclusion: There was a shift toward supplements rather than enteric hyperoxaluria as a leading cause of secondary oxalate nephropathy during the COVID-19 pandemic. Kidney outcomes are better than those observed for enteric hyperoxaluria, if the offending agent is identified and removed.
RESUMO
We report a case of occlusion of a graft related to residual thrombus collection at the inflow in a blind pouch formed by conversion of a previous brachial cephalic fistula to a graft. The thrombus was unable to be dislodged by conventional methods with the use of a Fogarty balloon and maceration of thrombus with angioplasty. A covered stent was placed at the inflow segment over this thrombus in order to restore the flow through the graft. Angiographic evidence for this case is also reported.

CYP24A1 is an enzyme that inactivates vitamin D. Loss-of-function mutations in this enzyme are rare but have been linked with idiopathic infantile hypercalcemia as well as adult-onset nephrocalcinosis and nephrolithiasis. Genetic testing for this mutation should be considered in the presence of calciuria, elevated serum calcium, elevated 1,25-dihydroxyvitamin D, and suppressed parathyroid hormone. We present a case with these lab findings as well as an elevated 25-hydroxyvitamin D/24,25-dihydroxyvitamin D ratio in whom compound heterozygous CYP24A1 mutations were found. His hypercalciuria resolved and 1,25-vitamin D level improved with ketoconazole treatment. We suggest that it is clinically important to identify patients with this phenotype as testing and treatment options are available which could reduce progression to chronic kidney disease in this population.
RESUMO
Parvovirus B19, the agent responsible for fifth disease, has been emerging as a significant pathogenetic factor in various acute vasculitic syndromes such as Wegener's granulomatosis, Henoch-Schönlein purpura, and Kawasaki disease. It has also been implicated in more chronic vasculopathic syndromes, specifically in the context of scleroderma and dermatomyositis. The basis of this association is likely multifactorial; implicated mechanisms include the virus's affinity for endothelium, resulting in a state of neoantigenicity through varied mechanisms as well as the induction of tumor necrosis factor alpha, a factor involved in the propagation of ANCA-positive vasculitic syndromes. The authors present a series of 12 patients with interstitial lung disease including idiopathic pulmonary fibrosis, scleroderma-associated pulmonary fibrosis, lymphocytic interstitial pneumonitis, and septal capillaritis. In all cases there was evidence of chronic parvovirus B19 infection based on serologic assessment and the isolation of B19 DNA on lung samples in all patients. Furthermore, in two cases there was in situ localization of B19 RNA and tumor necrosis factor alpha to endothelium and stromal cells. On pathologic examination, there were varying degrees of both septal fibrosis and inflammation along with evidence of septal capillary injury. In those cases categorized as representing either scleroderma or idiopathic pulmonary fibrosis, the immunofluorescent studies showed evidence of anti-endothelial cell antibody formation. The ANCA-associated syndromes were, as expected, negative by fluorescent analysis. Significantly elevated factor VIII levels, a standard serologic index of endothelial cell injury, were seen in four of the six patients tested. The antiphospholipid profile revealed antiphospholipids in 7 of the 11 patients tested. This report highlights a possible causal role for parvovirus B19 in the pathogenesis of select pulmonary disorders.

We recently reported on the use of an indirect immunofluorescent method designated the rodent lung assay; this test assesses for the presence of circulating antibodies directed at components of the microvasculature. Serum samples from 49 patients with scleroderma were incubated with rodent lung tissue sections and visualized with fluoresceinated human anti-IgG. The assay also was performed on samples from a control group. Western blot analysis was performed with endothelial cell protein extracts using serum samples from patients with scleroderma and from healthy control subjects. The control subjects had a negative indirect immunofluorescent assay result. In the patients with scleroderma, there was a significant positive correlation between intensity of indirect immunofluorescent staining and pulmonary fibrosis (r = 0.316; P = .0347) and hypertension (r = 0.310; P = .0408). Western blot analysis revealed antibody binding to proteins in extracts of human endothelial cells in all patients in whom there was evidence of pulmonary disease. The indirect immunofluorescent rodent lung assay and Western blot data support a potential role of anti-endothelial cell antibodies in the propagation of scleroderma-associated pulmonary disease.
