Once-per-week haemodialysis in a financial crisis: Predictors of interdialytic weight gain.

BACKGROUND: Several countries are experiencing challenges in maintaining standard haemodialysis services for people with kidney failure. OBJECTIVE: This study aimed to investigate the health profile of people receiving haemodialysis and to identify factors associated with interdialytic weight gain. DESIGN: A cross-sectional study. PARTICIPANTS: A total of 166 adults with kidney failure and receiving haemodialysis for at least 3 months were included. MEASUREMENTS: A structured chart audit form collected, demographic and haemodialysis treatment characteristics, recent biochemical and haematological results, and prescribed treatment regimens from clinical records. Data were analysed descriptively. Odds ratios (OR) were calculated to identify independent risk factors for interdialytic weight gain. RESULTS: Mean age was 52 years (SD = 12.5), over half were male (60.2%, n = 100), and most were receiving 4 h of haemodialysis once per week (87.3%, n = 145). Approximately half (51.8%, n = 86) had an interdialytic weight gain >2%. Being female (OR = 3.39; 95% CI, 1.51-7.61), increased comorbidities (OR = 1.50; 95% CI, 1.22-1.84) and having BMI outside of the normal range (overweight/obese [OR = 8.49; 95% CI, 3.58-20.13] or underweight [OR = 4.61; 95% CI, 1.39-15.31]) were independent risk factors for increased interdialytic weight gain. CONCLUSION: Most patients were receiving 4 h of haemodialysis once per week although only modest alterations in potassium, phosphate, and fluid status were observed. Understanding the patient profile and predictors of interdialytic weight gain will inform the development of self-management interventions to optimise clinician support.

The Association Between Web-Based or Face-to-Face Lifestyle Interventions on the Perceived Benefits and Barriers to Exercise in Midlife Women: Three-Arm Equivalency Study.

BACKGROUND: Noncommunicable diseases pose a significant threat to women's health globally, with most diseases being attributed to modifiable risk factors such as physical inactivity. Women perceive a range of benefits and barriers to exercise; however, there is little evidence about the effect of different lifestyle intervention delivery modes on perceptions of exercise. OBJECTIVE: This study aimed to compare the effect of a multiple health behavior change (MHBC) intervention called the Women's Wellness Program. This intervention was delivered in 3 different modes on perceived exercise benefits, perceived exercise barriers, and actual physical activity and exercise in midlife women. METHODS: Women aged 45 to 65 years were recruited via the study website. They were assigned in blocks to 3 different treatment groups (A: Web-based independent; B: face-to-face with nurse consultations; and C: Web-based with virtual nurse consultations). All participants received the 12-week intervention that utilizes principles from social-cognitive theory to provide a structured guide to promote healthy lifestyle behaviors with an emphasis on regular exercise and healthy eating. Data were collected using a self-report Web-based questionnaire at baseline (T1) and postintervention (T2) including perceived exercise benefits and barriers and exercise and physical activity. A data analysis examined both within- and between-group changes over time. RESULTS: Participants in this study (N=225) had a mean age of 50.9 years (SD 5.9) and most were married or living with a partner (83.3%, 185/225). Attrition was 30.2% with 157 participants completing the final questionnaire. Women in all intervention groups reported a significant increase in positive perceptions of exercise (P<.05); a significant increase in exercise and overall physical activity (P<.01) with moderate-to-large effect sizes noted for overall physical activity (d=0.5 to d=0.87). Participants receiving support from registered nurses in the face-to-face and Web-based groups had a greater magnitude of change in benefit perceptions and physical activity than those in the Web-based independent group. There was no significant change in exercise barrier perceptions within or between groups over time. CONCLUSIONS: The results of this study suggest that the (MHBC) intervention is effective in increasing exercise benefit perceptions, overall physical activity, and exercise in midlife women. Although Web-based programs are cost-effective and flexible and can be delivered remotely, providing a range of options including face-to-face group delivery and personalized electronic health coaching from registered nurses has the potential to enhance participant engagement and motivation.

Menopausal symptom clusters and their correlates in women with and without a history of breast cancer: a pooled data analysis from the Women's Wellness Research Program.

OBJECTIVES: This analysis examined climacteric symptoms clusters in women with and without breast cancer, and explored how sociodemographic, health, and modifiable lifestyle factors predicted symptom clusters. METHODS: This pooled analysis of four Women's Wellness Research Program (WWRP) studies comprised individual-level data from 969 Australian women aged 40 to 63 years, 293 of whom had been previously treated for breast cancer and 678 without a breast cancer history. Climacteric symptoms, menopausal status, sociodemographic characteristics, and health and lifestyle factors were assessed. Principal component analysis was used to determine symptom clusters for each group separately before linear regression with backwards selection was used to identify the significant correlates of the identified clusters. RESULTS: Women with a history of breast cancer reported more sleep disturbance (P < 0.01), difficulty concentrating (P < 0.01), muscular/joint pain (P < 0.01), crying (P < 0.01) and irritability (P < 0.01), and vasomotor symptoms (P < 0.01) than women from the noncancer group. Principal component analysis with quartimax rotation revealed two distinct solutions explaining 60.9% and 57.6% of the variance in the groups, respectively. For both groups, symptom clusters were increased among those with unhealthy lifestyle behaviors (and chemotherapy among the after cancer group, P < 0.05 for all), though to a lesser extent in the breast cancer group. CONCLUSIONS: In this study, women after treatment for breast cancer reported a broad range of bothersome climacteric symptoms. Similar symptom clusters were also noted for women with and without a history of breast cancer, though correlates differed across groups, and might reflect different underlying etiologies.

Factors predicting barriers to exercise in midlife Australian women.

OBJECTIVES: Chronic diseases are the leading cause of death and disability worldwide. They are, though, largely attributable to modifiable lifestyle risk factors, including lack of exercise. This study aims to investigate what factors predict perceptions of barriers to exercise in midlife women. STUDY DESIGN: This cross-sectional descriptive study collected data from midlife Australian women by online questionnaire. Volunteers aged between 40 and 65 years were recruited following media publicity about the study. MAIN OUTCOME MEASURES: The primary outcome measure was perceived exercise barriers (EBBS Barriers sub-scale). Other self-report data included: exercise, smoking, alcohol, fruit and vegetable consumption, body mass index, physical and mental health and well-being (MOS SF-12v2) and exercise self-efficacy. RESULTS: On average, the 225 participants were aged 50.9 years (SD=5.9). The significant predictors of perceived barriers to exercise were perceived benefits of exercise, exercise self-efficacy, physical well-being and mental well-being. These variables explained 41% of the variance in the final model (F (8219)=20.1, p<.01) CONCLUSIONS: In midlife women, perceptions of barriers to exercise correlate with beliefs about the health benefits of exercise, exercise self-efficacy, physical and mental well-being. These findings have application to health promotion interventions targeting exercise behaviour change in midlife women.

Decreasing menopausal symptoms in women undertaking a web-based multi-modal lifestyle intervention: The Women's Wellness Program.

Menopausal transition can be challenging for many women. This study tested the effectiveness of an intervention delivered in different modes in decreasing menopausal symptoms in midlife women. The Women's Wellness Program (WWP) intervention was delivered to 225 Australian women aged between 40 and 65 years through three modes (i.e., on-line independent, face-to-face with nurse consultations, and on-line with virtual nurse consultations). All women in the study were provided with a 12-week Program Book outlining healthy lifestyle behaviors while women in the consultation groups were supported by a registered nurse who provide tailored health education and assisted with individual goal setting for exercise, healthy eating, smoking and alcohol consumption. Pre- and post-intervention data were collected on menopausal symptoms (Greene Climacteric Scale), health related quality of life (SF12), and modifiable lifestyle factors. Linear mixed-effect models showed an average 0.87 and 1.23 point reduction in anxiety (p<0.01) and depression scores (p<0.01) over time in all groups. Results also demonstrated reduced vasomotor symptoms (ß=-0.19, SE=0.10, p=0.04) and sexual dysfunction (ß=-0.17, SE=0.06, p<0.01) in all participants though women in the face-to-face group generally reported greater reductions than women in the other groups. This lifestyle intervention embedded within a wellness framework has the potential to reduce menopausal symptoms and improve quality of life in midlife women thus potentially enhancing health and well-being in women as they age. Of course, study replication is needed to confirm the intervention effects.

Preclinical assessment of adjunctive tPA and DNase for peritoneal dialysis associated peritonitis.

A major complication of peritoneal dialysis is the development of peritonitis, which is associated with reduced technique and patient survival. The inflammatory response elicited by infection results in a fibrin and debris-rich environment within the peritoneal cavity, which may reduce the effectiveness of antimicrobial agents and predispose to recurrence or relapse of infection. Strategies to enhance responses to antimicrobial agents therefore have the potential to improve patient outcomes. This study presents pre-clinical data describing the compatibility of tPA and DNase in combination with antimicrobial agents used for the treatment of PD peritonitis. tPA and DNase were stable in standard dialysate solution and in the presence of antimicrobial agents, and were safe when given intraperitoneally in a mouse model with no evidence of local or systemic toxicity. Adjunctive tPA and DNase may have a role in the management of patients presenting with PD peritonitis.
