Making lifestyle changes after colorectal cancer: insights for program development.

BACKGROUND: Healthy lifestyle behaviours may improve outcomes for people with colorectal cancer (crc), but the intention to take action and to change those behaviours may vary with time and resource availability. We aimed to estimate the prevalence of current lifestyle behaviours in people with and without crc in our community, and to identify their desire to change and their resource preferences. METHODS: A mixed-methods survey was completed by people diagnosed with crc who were pre-treatment (n = 54), undergoing treatment (n = 62), or done with treatment for less than 6 months (n = 67) or for more than 6 months (n = 178), and by people without cancer (n = 83). RESULTS: Current lifestyle behaviours were similar in all groups, with the exception of vigorous physical activity levels, which were significantly lower in the pre-treatment and ongoing treatment respondents than in cancer-free respondents. Significantly more crc respondents than respondents without cancer had made lifestyle changes. Among the crc respondents, dietary change was the change most frequently made (39.3%), and increased physical activity was the change most frequently desired (39.1%). Respondents wanted to use complementary and alternative medicine (cam), reading materials, self-efficacy, and group activities to make future changes. CONCLUSIONS: Resources for lifestyle change should be made available for people diagnosed with crc, and should be tailored to address physical activity, cam, and diet. Lifestyle programs offered throughout the cancer trajectory and beyond treatment completion might be well received by people with crc.

Information needs across the colorectal cancer care continuum: scoping the literature.

Because cancer care requires a multifaceted approach, providing useful and timely information to people with colorectal cancer may be fragmented and inconsistent. Our interest was in examining what has and has not captured the attention of researchers speaking to the information needs of people with colorectal cancer. We followed Arksey and O'Malley's framework for the methodology of scoping review. Focusing solely on colorectal cancer, we analysed 239 articles to get a picture of which information needs and sources of information, as well as the timing of providing information, were attended to. Treatment-related information received the most mentions (26%). Healthcare professionals (49%) were mentioned as the most likely source of information. Among articles focused on one stage of the care continuum, post-treatment (survivorship) received the most attention (16%). Only 27% of the articles consulted people with colorectal cancer and few attended to diet/nutrition and bowel management. This study examined the numerical representation of issues to which researchers attend, not the quality of the mentions. We ponder, however, on the relationship between the in/frequency of mentions and the actual information needs of people with colorectal cancer as well as the availability, sources and timing of information.

Hematological complications and quality of life in hospitalized AIDS patients.

The relationships among the biological and physiological indicators of cytopenias in AIDS and measures of quality of life are not well characterized. The purpose of this secondary analysis was to determine the relationships among anemia, neutropenia and thrombocytopenia and characteristics of the individual, physiological markers, symptoms, functional status, general health perceptions, and well-being in people with AIDS. The five dimensions of the Wilson and Cleary model of health-related quality of life provided the conceptual model for this study. In addition to descriptive statistics, logistic regression was used to analyze clusters of variables. The sample of 146 hospitalized patients with AIDS had an 85% prevalence of anemia, a 53% prevalence neutropenia and a 33% prevalence of thrombocytopenia. The mean age was 38 years old, 19% were female, 35% were white, 27% had a history of injection drug use and the mean T-helper cell count was 74 mm3. The five dimensions of the Wilson and Cleary model offered significant predictability for anemia only. Patients with higher symptom scores were more likely to have treatable anemia, defined as a hematocrit of < 30%. Treatable anemia was also associated with lower self-care scores and lower T-helper cells. Fifty-four percent of the cohort were candidates for colony stimulating factors, while only 17% of those eligible received them. These data suggest suboptimal treatment of anemia and neutropenia in this cohort of AIDS patients.

Intralesional vinblastine for cutaneous Kaposi's sarcoma associated with acquired immunodeficiency syndrome. A clinical trial to evaluate efficacy and discomfort associated with infection.

BACKGROUND: Intralesional vinblastine has been used to treat Kaposi's sarcoma associated with acquired immunodeficiency syndrome (AIDS-KS). Injections are painful and anticipated response rates are not well documented. OBJECTIVE: Eleven homosexual men were studied to evaluate the efficacy and pain associated with intralesional vinblastine with or without 1% bicarbonate buffered lidocaine (BBL). METHODS: Six lesions on each patient were selected and treated with either vinblastine, vinblastine mixed with BBL, or vinblastine 5 minutes after BBL injection. Control lesions received BBL, saline, or no treatment. Patients recorded injection pain on a visual analog scale. RESULTS: There was a complete or partial clinical response in 88% of vinblastine-treated lesions. Pain scores for BBL, vinblastine, and the mixture of BBL and vinblastine were not statistically different. CONCLUSION: Intralesional vinblastine is effective therapy for AIDS-KS. Local anesthesia does not reduce efficacy of treatment, or reduce the pain experienced by the patient.

Early findings from a pharmacokinetically designed double-blind and placebo-controlled study of lithium for adolescents comorbid with bipolar and substance dependency disorders.

1. This manuscript reports the early findings from a National Institute on Drug Abuse funded study of lithium for adolescents dually diagnosed with bipolar and substance dependency disorders. The authors elected to publish early findings in the hope that it would accomplish a twofold mission. 2. The first part would be to encourage other investigators to participate in research in this area and the second would be to heighten the awareness of clinicians that adolescents presenting with either one of these disorders might also have the other. 3. The early findings demonstrated the feasibility of recruiting, retaining and monitoring this complex population on an outpatient basis. 4. Steady-state serum lithium levels were pharmacokinetically placed in the study range, 0.9-1.3 mEq/L. Preliminary results are encouraging in finding lithium more effective than placebo for alleviating both the substance dependency and the mood disordered symptomatology. 5. The characteristics of the study population to date have been chronicity of both disorders, impairment in the severe range in multiple areas of functioning, and strong family histories for both affective and substance use disorders. The substance dependency was to both alcohol and marijuana; but all subjects also had marked polydrug abuse. 6. In order to best monitor lithium compliance and drug/alcohol use during protocol, randomly timed weekly serum and urine assays were obtained. 7. The implications of these early findings for the outcome of this acute phase study and for the development of longitudinal treatment strategies are discussed.

Logistic analysis of risk factors in acute retinopathy of prematurity.

In a prospective study of 328 high-risk neonates, we used computer-assisted logistic regression of 47 potential risk factors to study acute retinopathy of prematurity. Only four factors were significant in the logistic regression equation: ventilator hours, xanthine administration, birthweight, and maternal bleeding. Xanthine administration was identified as a new independent and significant (P less than .0001) predictor of acute retinopathy of prematurity.
