Black Patients Equally Benefit From Renal Genetics Evaluation but Substantial Barriers in Access Exist.

Introduction: Genetic testing is increasingly accessible to patients with kidney diseases. Racial disparities in renal genetics evaluations have not been investigated. Methods: A cohort of patients evaluated by the Cleveland Clinic Renal Genetics Clinic (RGC) from January 2019 to March 2022 was analyzed. Results: Forty-eight Black patients, including 27 (56.3%) males, median age 34 (22-49) years and 232 White patients, including 76 (32.8%) males, median age 35 (21-53) years, were evaluated. Black patients were more likely to have end-stage kidney disease (ESKD) at the time of referral compared with White patients (23% vs. 7.3%, P = 0.004), more likely to be covered by Medicaid (46% vs. 15%, P < 0.001), and less likely to be covered by private insurance (35% vs. 66%, P < 0.001). Black patients were more likely to "no show" to scheduled appointment(s) or not submit specimens for genetic testing compared with White patients (24.1% vs. 6.7%, P = 0.0005). Genetic testing was completed in 35 Black patients. Of these, 37% had a positive result with 9 unique monogenic disorders and 1 chromosomal disorder diagnosed. Sixty-nine percent of Black patients with positive results received a new diagnosis or a change in diagnosis. Of these, 44% received a significant change in disease management. No differences in diagnostic yield and implications of management were noted between Black and White patients. Conclusion: Black patients equally benefit from renal genetics evaluation, but barriers to access exist. Steps must be taken to ensure equitable and early access for all patients. Further studies investigating specific interventions to improve access are needed.

The Sarawak Myelofibrosis (SaMy) experience: Demographics and outcome of myelofibrosis patients in Sarawak, Malaysia.

Introduction: Myelofibrosis is a rare disease. There is currently no published data reporting the demographics and outcome of myelofibrosis patients in Malaysia. We aimed to study the demographics, clinical characteristics, and outcome of our patients in Sarawak. Materials and methods: This non-interventional, retrospective, and multi-center study was conducted on secondary data of medical records collected at four Sarawak Public Hospitals. All adult myelofibrosis patients diagnosed between January 2001 and December 2021 were included. Results: A total of 63 patients (male 31) with myelofibrosis were included-47 (74.6%) primary and 16 (25.4%) secondary myelofibrosis. Eleven had antecedent polycythaemia vera, whereas five transformed from essential thrombocythaemia. The combined annual incidence rate was 0.182 per 100,000 population. The period prevalence per 100,000 population over the entire study duration was 2.502. The median age was 59.0 years (33.0-93.0). Majority had high-risk (34/63(54.0%)) and intermediate-2 risk disease (19/63(30.2%)). JAK2V617F mutation was identified in 52 patients (82.5%), followed by CALR mutation in 6 (9.5%) and negative for both mutations in 5 (7.9%). Hydroxyurea was used as first-line therapy in 41/63 (65.1%), followed by interferon (8/63(12.7%)) and ruxolitinib (4/63(6.3%)). Out of 46 patients who received second-line therapy, 18 (39.1%) were switched to ruxolitinib and 9 (19.6%) to interferon. The median age of survival for overall patients was 6.8 years. The use of ruxolitinib in myelofibrosis patients showed a better overall 5-year survival compared to the no ruxolitinib arm, despite no statistical significance (p = 0.34). Patients who had good performance status had lower hazard of death than patients who had poor performance status (high-risk (95% confidence intervals): 0.06(0.013-0.239), p < 0.001). Patients with intermediate risk disease had better overall survival compared to those in high-risk group (95% confidence intervals): 0.24(0.082-0.695), p = 0.009). Conclusion: This registry provides a real-world overview of myelofibrosis patients in our state and highlights the key insight into the unmet clinical need.

Renal Genetics Clinic: 3-Year Experience in the Cleveland Clinic.

Rationale & Objective: There has been an increasing demand for the expertise provided by a renal genetics clinic. Such programs are limited in the United States and typically operate in a genomics research setting. Here we report a 3-year, real-world, single-center renal genetics clinic experience. Study Design: Retrospective cohort. Setting & Participants: Outpatient cases referred to the renal genetics clinic of the Cleveland Clinic between January 2019 and March 2022 were reviewed. Analytical Approach: Clinical and laboratory characteristics were analyzed. All genetic testing was performed in clinical labs. Results: 309 new patients referred from 15 specialties were evaluated, including 118 males and 191 females aged 35.1 ± 20.3 years. Glomerular diseases were the leading presentation followed by cystic kidney diseases, electrolyte disorders, congenital anomalies of kidneys and urinary tract, nephrolithiasis, and tubulointerstitial kidney diseases. Dysmorphic features were noted in 27 (8.7%) patients. Genetic testing was recommended in 292 (94.5%) patients including chromosomal microarray (8.9%), single-gene tests (19.5%), multigene panels (77.3%), and exome sequencing (17.5%). 80.5% of patients received insurance coverage for genetic testing. 45% (115/256) of patients had positive results, 25% (64/256) had variants of unknown significance, and 22.3% (57/256) had negative results. 43 distinct monogenic disorders were diagnosed. Family history of kidney disease was present in 52.8% of patients and associated with positive genetic findings (OR, 2.28; 95% CI, 1.40-3.74). 69% of patients with positive results received a new diagnosis and/or a change in the diagnosis. Among these, 39.7% (31/78) of patients received a significant change in disease management. Limitations: Retrospective and single-center study. Conclusions: The renal genetics clinic plays important roles in the diagnosis and management of patients with genetic kidney diseases. Multigene panels are the most frequently used testing modality with a high diagnostic yield. Family history of kidney disease is a strong indication for renal genetics clinic referral.

Extraosseous calcification in kidney disease.

A consequence of chronic and end-stage kidney disease is a higher risk of calcium deposition in sites other than the bones. The authors of this review outline current understanding of the pathogenesis, presentation, diagnosis, and treatment of this group of disorders.

HR practices and turnover intention; the mediating role of organizational commitment in Tehran: a cross-sectional study.

Background: Employees are increasingly being recognised as a valuable source of information, especially in knowledge-based businesses. Businesses, however, suffer financial and organisational memory losses related to re-hiring and training new staff, and lost productivity and intellectual property because of employee turnover. Hence, employee turnover should be considered an essential part of human resource management. Furthermore, employees' trust in management and human resource (HR) practices substantially impact organisational commitment (OC). Thus, anticipating employee commitment and turnover intentions is crucial, as people are the sole source for knowledge-based firms to maintain their competitive advantage. In the context of selected Tehran Renewable Energy (RE) firms, this study investigated the mediating impact of OC on the relationship between HR practices (recruitment and selection; training and development opportunities; performance appraisal and evaluation; teamwork; compensation and pay; and job security) and employee turnover intention. Methods: This is a cross-sectional study in Tehran that involved 90 experts and knowledgeable employees from four of Tehran's top RE businesses. A questionnaire was distributed to collect data which was later analysed with correlation, regression and bootstrapping analyses. Results: All six dimensions of HR practices were discovered to have an indirect impact on turnover intention and a direct impact on OC. OC among employees has an indirect effect on turnover intention. It was also revealed that the training and development opportunity has the most considerable effect on OC and turnover intention. OC was not found as a mediator between HR practices and turnover intention. Conclusions: The outcomes of this study showed that both training and development opportunities; and pay and compensation structure were found to be two significant components of HR practices in the relationship with OC. RE managers should employ appropriate HR strategies, particularly in these two dimensions, to improve an individual's degree of OC and reduce turnover intention.

Dunbar syndrome: An unusual cause of chronic postprandial abdominal pain.

Median arcuate ligament syndrome (MALS), also known as Dunbar syndrome, is a rare condition in which the celiac artery is compressed by the median arcuate ligament of the diaphragm. We hereby report a case of a 48-year-old female presenting with long-standing abdominal pain and ninety-pound weight loss who was found to have median arcuate ligament syndrome after extensive workup.
