Fatigue by the Chalder Questionnaire and post-hemodialysis recovery in a population of predominantly African descent: The PROHEMO.

Background/objective: A high prevalence of fatigue and a positive association between fatigue and post-hemodialysis recovery have been reported in predominantly white populations of maintenance hemodialysis (MHD) patients. The present study evaluates associations between self-reported fatigue by the 11-item Chalder Fatigue Questionnaire (CFQ-11) and the need for post-hemodialysis recovery in a predominantly African-descent MHD population.

Methods: A total of 233 patients (94% Black or Mixed-Race) participating in the "Prospective Study of the Prognosis of Patients on Maintenance Hemodialysis" (PROHEMO), Salvador, Brazil were recruited for this cross-sectional study.

Self-Reported Fatigue by the Chalder Fatigue Questionnaire and Mortality in Brazilian Hemodialysis Patients: The PROHEMO.

Background: The existing data support the Chalder Fatigue Questionnaire (CFQ-11) as a valid instrument to assess fatigue in maintenance hemodialysis (MHD) patients. The objective of this work was to investigate whether self-reported fatigue can serve as an independent prognostic indicator for mortality in MHD patients.

Methods: The data are from 233 adult patients enrolled in the cohort "The Prospective Study of the Prognosis of Chronic Hemodialysis Patients" (PROHEMO) developed in Salvador, BA, Brazil.

Functional dependence and the mental dimension of quality of life in Hemodialysis patients: the PROHEMO study.

Background: Functional dependence is highly prevalent in maintenance hemodialysis (MHD) settings. Also, poor health-related quality of life (HRQoL) and high levels of depressive symptoms have been reported by MHD patients. We investigated associations between functional status and mental aspects of quality of life in Brazilian MHD patients.

John Henryism and Perceived Health among Hemodialysis Patients in a Multiracial Brazilian Population: the PROHEMO.

Purpose: John Henryism (JH) is a strong behavioral predisposition to engage in high-effort coping with difficult socioenvironmental stressors. We investigated associations between JH and perceived general health (GH) among maintenance hemodialysis (MHD) patients in a multiracial Brazilian population.

Design: The 12-item John Henryism Acting Coping (JHAC) Scale was completed by 525 patients enrolled in The Prospective Study of the Prognosis of Hemodialysis Patients (PROHEMO) in Salvador (Bahia) Brazil.

Additional Contribution of the Malnutrition-Inflammation Score to Predict Mortality and Patient-Reported Outcomes as Compared With Its Components in a Cohort of African Descent Hemodialysis Patients.

Objective: The malnutrition-inflammation score (MIS) combines ten components to assess nutritional status. Higher MIS has been associated with higher mortality and poorer health-related quality of life (HRQOL) in maintenance hemodialysis (MHD) patients. It is interesting to investigate associations of each component with mortality and patient-reported outcomes (PROs), that is, HRQOL and depression symptoms, and if MIS associations are generalizable for diverse populations.

Patient's response to a simple question on recovery after hemodialysis session strongly associated with scores of comprehensive tools for quality of life and depression symptoms.

Purpose: Many maintenance hemodialysis patients do not feel well after the hemodialysis session and need a time to recover. The main objective of the study was to investigate whether a simple question about the need of some time to recover from hemodialysis was associated with scores of comprehensive tools of depression symptoms and health-related quality of life (HRQOL).

Methods: Cross-sectional evaluation of 800 Brazilian patients enrolled in the Prospective Study of the Prognosis of Chronic Hemodialysis Patients (PROHEMO).

Handgrip strength at baseline and mortality risk in a cohort of women and men on hemodialysis: a 4-year study.

Objective: The objective of this study was to investigate the association between handgrip strength (HGS) and the risk of all-cause mortality in maintenance hemodialysis (MHD) patients and its relationship with nutritional status. This study also investigated whether the association between HGS and mortality is similar in female and male patients.

Design And Methods: This was a cohort study using data from the Prospective Study of the Prognosis of Chronic Hemodialysis Patients (PROHEMO) with a median follow-up of 33.

Potentially modifiable factors associated with non-adherence to phosphate binder use in patients on hemodialysis.

Background: Despite the evidence that phosphate binder (PB) is associated with improved outcomes many hemodialysis patients do not adhere to prescribed PB regimen. Therefore, barriers to PB adherence should be identified and eliminated. The purpose of this study was to evaluate PB adherence among hemodialysis patients and to explore potentially modifiable factors associated with low PB adherence.

Gastrointestinal symptoms and nutritional status in women and men on maintenance hemodialysis.

Objective: The main objective was to investigate whether the prevalences of nausea, vomiting, diarrhea, and reduced appetite varied by gender in maintenance hemodialysis (MHD) patients. We also evaluated whether these symptoms explain female-male difference in nutritional status.

Design: Cross section of baseline data of the Prospective Study of the Prognosis in Chronic Hemodialysis Patients.

Assessment of the psychological burden associated with pruritus in hemodialysis patients using the kidney disease quality of life short form.

Purpose: To assess whether depression symptoms, poor sleep and dry skin bother explain association between pruritus and the burden of kidney disease in maintenance hemodialysis (MHD) patients.

Methods: Cross-sectional study of 980 patients from a prospective study in dialysis units of Salvador, Brazil (PROHEMO). The Kidney Disease Quality of Life Short Form was used to determine scores of kidney disease burden (KDB) and sleep with higher scores indicating lower perceived burden and better sleep quality, respectively.

Handgrip strength as a simple indicator of possible malnutrition and inflammation in men and women on maintenance hemodialysis.

Objective: To assess the validity of handgrip strength (HGS) as a simple screening instrument for malnutrition and inflammation in patients on maintenance hemodialysis (MHD) by correlating it with malnutrition-inflammation score (MIS).

Design: Cross-sectional analysis of the Prospective Study of the Prognosis in Chronic Hemodialysis Patients (PROHEMO).

Setting: Satellite dialysis units in the city of Salvador, Brazil.

Depression as a potential explanation for gender differences in health-related quality of life among patients on maintenance hemodialysis.

Background/aims: The reasons for lower health-related quality of life (HRQOL) scores in women compared to men on maintenance hemodialysis (MHD) are unknown. We investigated whether depression accounts for gender differences in HRQOL.

Methods: Cross-sectional study of 868 (40.

[Prescription of phosphorus binders and calcitriol for chronic hemodialysis patients].

Objective: To describe the frequency of prescription of phosphate binders (PB) and calcitriol for patients on chronic hemodialysis in Salvador, Brazil, and to assess whether treatment is in agreement with recommendations of the Kidney Disease Outcomes Quality Initiative (K/DOQI).
