RESUMEN
OBJECTIVE: To examine the relationship of the symptoms of diarrhea and fatigue by testing a model that included multiple dimensions of the cancer related-symptom experience. METHODS: A secondary data analysis was conducted on data from the self-reports of 102 cancer patients co experiencing diarrhea and fatigue during treatment at a comprehensive cancer center in the Southeastern United States. Structural equational modeling was employed to examine the relationship between the 2variables. Fatigue and diarrhea were assessed using items from the Cancer Symptom Scale. RESULTS: The structural model results showed that (a) the model fit was adequate (b) diarrhea explained 7% of the variance in fatigue, and (c) the structural or path coefficient between diarrhea and fatigue was significant (0.267; p<0.05). Diarrhea had the strongest effect on fatigue interference (0.251). CONCLUSION: Diarrhea is a potential contributing factor to the symptom of fatigue and a potential target for interventions to prevent and ameliorate fatigue.

OBJECTIVE: To examine the health related quality of life (HRQOL) experienced by 79 Puerto Rican adults during cancer treatments. METHODS: This study used a descriptive, cross-sectional design. Participants completed a demographics form and the Functional Assessment of Cancer Therapy-General QOL questionnaire (FACT-G). Descriptive statistics were generated. RESULTS: Participants were ages 28-78; most of the participants had breast (38.0%), prostate (14.0%) and cervical and ovarian cancers (10.1%) treated with chemotherapy (45.6%). The participants had a mean total score on the FACT-G of 75.2 (SD = 18.9). As a group, the functional well-being was the most affected (mean 17.2, SD 6.8), and the Social/Familial was the least affected (mean 20.7, SD 6.0). CONCLUSION: Cancer is the leading cause of death in the island of Puerto Rico. Female Puerto Rican cancer patients in this study sample had increased risk for experiencing worse: overall HRQOL, physical well-being and emotional well-being compared to males. Given that the Hispanic oncology population does not always report symptoms, risking under-assessment and under management, this suggests there may be a greater need for HRQOL surveillance for this population.

Genetic factors that influence inflammation and energy production/expenditure in cells may affect patient outcomes following treatment with external beam radiation therapy (EBRT). Sestrins, stress-inducible genes with antioxidant properties, have recently been implicated in several behaviors including fatigue. This proof-of-concept study explored whether the sestrin family of genes ( SESN1, SESN2, and SESN3) were differentially expressed from baseline to the midpoint of EBRT in a sample of 26 Puerto Rican men with nonmetastatic prostate cancer. We also examined whether changes in expression of these genes were associated with changes in fatigue scores during EBRT. METHOD: Participants completed the 13-item Functional Assessment of Cancer Therapy-Fatigue subscale, Spanish version. Whole blood samples were collected at baseline and at the midpoint of EBRT. Gene expression data were analyzed using the limma package in the R (version R 2.14.0.) statistical software. Linear models and empirical Bayes moderation, adjusted for radiation fraction (total number of days of prescribed radiation treatment), were used to examine potential associations between changes in gene expression and change in fatigue scores. RESULTS: Expression of SESN3 (adjusted p < .01, log fold change -0.649) was significantly downregulated during EBRT, whereas the expressions of SESN1 and SESN2 remained unchanged. After adjustment for radiation fraction, change in SESN3 expression was associated with change in fatigue during EBRT (false discovery rate <.01). CONCLUSIONS: Downregulation of SESN3, a novel pharmacoactive stress response gene, was associated with fatigue intensification during EBRT. SESN3 may serve as an interventional target and a biomarker for the cellular and molecular events associated with EBRT-related fatigue.

AIMS AND OBJECTIVES: To describe differences in fatigue severity in a sample of adult Puerto Rican patients during and postcancer treatments. BACKGROUND: Hispanics, including Puerto Ricans, are an understudied population who are under-represented in clinical trials, especially in symptom research. Although symptom management is a clinical priority in oncology care, treatment-related differences in Puerto Rican cancer patients' report of fatigue severity have not been well described. DESIGN/METHODS: A cross-sectional survey was conducted from data of self-report of 138 Puerto Rican patients during and postcancer treatments at two ambulatory facilities located in San Juan, Puerto Rico. Fatigue severity was assessed using the Fatigue subscale from the Functional Assessment of Cancer Therapy-Fatigue quality of life questionnaire Spanish version. Differences in fatigue severity across type of treatment (radiation therapy, chemotherapy, combined radiation chemotherapy and post-treatment) were evaluated using nonparametric (Kruskal-Wallis and Mann-Whitney test) statistical tests. RESULTS: The majority of the participants had prostate (33%) and breast (32%) cancers and were receiving radiation therapy (43%) or chemotherapy (28%). The Kruskal-Wallis test showed that there was a statistically significant difference in fatigue scores between the different four treatment conditions, χ2 (3) = 39.1, p = .001 with patients on combined radiation chemotherapy or chemotherapy alone experiencing more severe fatigue. CONCLUSIONS: Findings from the current study suggest that type of treatment is a key component of the symptom burden of fatigue among the Puerto Rican oncology population. Specially, patients receiving combined therapy or chemotherapy alone were at increased risk for experiencing severe fatigue, compared to radiation therapy and post-treatment patients. RELEVANCE TO CLINICAL PRACTICE: With the worldwide increase in migration of Puerto Rican families, nurses need to recognise that type of treatment is a key component of the symptom burden of fatigue among the Puerto Rican population. The results of this study will improve understanding of treatment-related fatigue to identify therapeutic targets and improve quality of life of patients.

OBJECTIVE: To examine the trajectory of fatigue experienced by 26 Puerto Rican (PR) men over the course of External Beam Radiation Therapy (EBRT) and to assess gene expression changes from baseline to midpoint of EBRT using microarray technology. Design/Research Approach- Prospective exploratory and comparative design study. Setting- RT facility located in San Juan, PR. Sample/Participants-26 PR men with non-metastatic prostate cancer. METHODS: Participants completed 2 paper forms: demographics and the Spanish version of the 13-item FACT-fatigue at baseline, midpoint, and end of EBRT. Wholeblood samples were collected at baseline and at midpoint of EBRT. Descriptive data was analyzed using t-test, Wilcoxon, and Friedman test for repeated measures. Gene expression data was analyzed using the LIMMA package in R; the functional network analysis was conducted using Ingenuity Pathway analysis. Main Research Variable-Fatigue scores, gene expression. RESULTS: Subjects were of ages 52-81 with fatigue scores that remained unchanged during EBRT (baseline=42.38, SD=9.34; midpoint=42.11, SD=8.93, endpoint=43.04, SD=8.62). Three hundred seventy-three genes (130-up regulated and 243-down regulated) were differentially expressed from baseline to mid-point of EBRT (FDR<0.01). The top distinct canonical pathways of the differentially expressed probesets (p<0.0001) were: "Phospholipase C Signaling," "Role of NFAT in Regulation of the Immune Response," and "Gαq Signaling." CONCLUSION: While fatigue did not worsen over the course of EBRT for this sample as a group, there was variability in fatigue across the sample. It is possible that the over expression of the SESN3 gene, known to suppress oxidative damage, may have contributed to the attenuation of fatigue in this clinical population.

BACKGROUND: Prostate cancer is the most frequently diagnosed cancer in men in Puerto Rico, and external beam radiation therapy (EBRT) is a popular treatment. Although symptom management is a clinical priority of comprehensive oncology care, symptom assessment at the time of primary or adjuvant EBRT has received limited attention. OBJECTIVES: This article examines the prevalence and severity of symptoms experienced by 54 Puerto Rican men prior to EBRT. METHODS: Participants completed a demographic form and the MD Anderson Symptom Inventory. Descriptive statistics were generated. FINDINGS: Most participants had received hormonal treatment, and about a third had received no treatment prior to EBRT. About a third of those who received hormonal treatment reported experiencing side effects before EBRT, and disturbed sleep, numbness and tingling, fatigue, and dry mouth were the most severe. Puerto Rican men with prostate cancer who receive hormonal treatment are at increased risk for experiencing symptom burden prior to EBRT. Greater need for symptom surveillance, treatment, and control may be needed among this population.

OBJECTIVE: Although opportunities to vaccinate against human papillomavirus (HPV) are available, vaccination rates in Puerto Rico remain low. Communication between parents and adolescents about sexual topics may influence decisions about HPV vaccination uptake, particularly among young women; yet, few studies have addressed this issue. This qualitative study explored Puerto Rican mothers' and daughters' communication on sex-related topics, and HPV, including the HPV vaccine. DESIGN: Thirty participants, including 9 mothers and 21 daughters, participated in seven focus groups. Participants were divided into groups of mothers and daughters, and further stratified by vaccination status. Transcripts were analyzed using a modified grounded theory approach to identify emergent themes. RESULTS: Focus group data revealed four main themes: (1) limited parent-daughter communication about sex-related topics; (2) daughters' discomfort discussing sex-related topics with their parents; (3) parental focus on abstinence; and, (4) limited parent-daughter communication about HPV and the HPV vaccine. CONCLUSION: Although daughters in this study struggled with feelings of embarrassment, invasion of privacy, encouragement of abstinence, and the fear of parents' reaction to them being sexually active prior to marriage, they also recognized the need to increase the parent-daughter communication about sex-related topics including HPV and the HPV vaccine. Educational efforts should target both daughters and parents to increase communication skills and self-efficacy and to enable them to discuss sexual health in open and nonjudgmental conversations.
