Incidence, mortality and relative survival of patients with cancer of the bladder and upper urothelial tract in the Nordic countries between 1990 and 2019.

PURPOSE: To understand the potential impact of new treatment options for urinary tract cancer, recent population trends in incidence, mortality and survival should be elucidated. This study estimated changes in the incidence, mortality and relative survival of urinary tract cancer in the Nordic countries (Denmark, Finland, Iceland, Norway and Sweden) between 1990 and 2019. METHODS: Annual counts of incident cases and deaths due to urinary tract cancer (International Classification of Diseases, Tenth Revision, Clinical Modification codes C65-C68, D09.0-D09.1, D30.1-D30.9 and D41.1-D41.9) in Nordic countries were retrieved in 5-year age categories by sex during the study period. Country-specific time trends (annual rate ratios [RRs]) were estimated using Poisson regression, and RRs were compared between sexes. RESULTS: The incidence rate of bladder and upper urothelial tract cancer was >3-times lower in women than men in all countries across all age groups (incidence RR for women to men ranging from 0.219 [95% CI = 0.213-0.224] in Finland to 0.291 [95% CI = 0.286-0.296] in Denmark). Incidence rates were lowest in Finland and highest in Norway and Denmark. Age-adjusted mortality decreased in Finland, Denmark and Norway and in Swedish men, with the greatest decrease seen in Danish men (annual RR = 0.976; 95% CI = 0.975-0.978). In all countries and age groups, women had a lower relative survival rate than men. CONCLUSION: Between 1990 and 2019, the incidence of urinary tract cancer was stable in the Nordic countries, while mortality rates declined and relative survival increased. This could be due to earlier diagnosis and better treatment.

Hemodialysis in hypotensive heart failure using midodrine.

BACKGROUND: Dialysis in patients with severe congestive heart failure and low blood pressure is difficult even in a hospital setting. We retrospectively recorded the effects and usefulness of an alpha (1) agonist in an outpatient dialysis unit in 5 patients with end-stage renal disease with symptomatic heart failure and low blood pressure. To provide outpatient dialysis, they were given midodrine before and during their dialysis sessions. METHODS: The volume of fluid removed, the lowest blood pressure, and postdialysis blood pressure measurements were recorded during a 3- to 4-week period just before initiating therapy (control period) and were compared with the measurements while using midodrine (treatment period). The blood pressures were expressed as the average of the mean arterial pressures (MAP). RESULTS: All patients had an increase in the lowest MAP during dialysis and in the postdialysis MAP. Each was significant at P = 0.03. Fluid removal was significant at P = 0.04. All the patients improved in their symptoms of orthopnea and shortness of breath. CONCLUSION: Outpatient dialysis is possible and relieves the symptoms of congestive heart failure in patients with poor heart function, low blood pressure, and advanced age when midodrine is given immediately before and during the procedure.

Hepatitis C infection is acquired pre-ESRD.

BACKGROUND: Hepatitis C is more prevalent in patients with end-stage renal disease (ESRD) than in the general population. Previously, infection from nosocomial sources was an important cause for this increase. In the past decade, the risk from these sources has lessened, but the estimated percentage of patients with ESRD with hepatitis C virus (HCV) antibody (anti-HCV) has not changed. METHODS: This is a prospective observational study of hemodialysis patients in 4 urban units in Birmingham, AL. Testing for anti-HCV was performed at the initiation of dialysis therapy and then yearly from August 1998 through August 2004. Race, sex, age, ESRD date, comorbid conditions, and outcomes were recorded. RESULTS: The prevalence of anti-HCV was 16.8% in 860 patients (89% black). Patients new to ESRD had a prevalence of 14.4%. Seroconversion in previously anti-HCV-negative patients was 2.5%. Anti-HCV occurred in black men 3 times more than in black women (odds ratio, 3.3; 95% confidence interval, 2.2 to 5.0). Mean age at ESRD was significantly younger in anti-HCV-positive than HCV-negative patients (47.3 versus 54.1 years; P < 0.0001). Age, race, sex, and history of drug abuse were predictors of anti-HCV positivity. CONCLUSION: The prevalence of anti-HCV among patients with ESRD varies from community to community. New patients are major contributors to the prevalence of anti-HCV in patients with ESRD, particularly those who are younger, male, black, or have a history of drug use. Measuring anti-HCV levels in patients with chronic kidney disease may help identify those at risk for additional disorders.
