Patient delay to diagnosis and its predictors among colorectal cancer patients: A cross-sectional study based on the Theory of Planned Behavior.

PURPOSE: The prognosis for colorectal cancer is closely related to the time of diagnosis. However, patient delay is common and become a major contributor to delays in cancer diagnosis. We aimed to investigate patient delay and its predictors based on the Theory of Planned Behavior among colorectal cancer patients. METHODS: In total, 303 colorectal cancer patients were recruited from a Grade-A tertiary cancer center in southern China by convenience sampling. The participants' general information, stigma, self-efficacy, and knowledge about colorectal cancer were assessed by a self-designed general information questionnaire, the Social Impact Scale, the General Self-Efficacy Scale, and the section of the Bowel Cancer Awareness Measure on total knowledge of colorectal cancer. Descriptive statistics, univariate analysis, and binary logistic regression were applied for data analysis. RESULTS: The median patient delay was four months (range: 1 day-10 years). The prevalence of prolonged patient delay (≥3 months) was 57.8%. Identified by binary logistic regression, prolonged patient delay was associated with having no close family members/friends in medical professionals, unwillingness to accept colonoscopy, blood in stools, dyspepsia, insufficient support from family members, more measures taken to control symptoms, lower perceived severity of symptoms, knowledge shortage, negative help-seeking attitudes, lower self-efficacy, and higher stigma. CONCLUSIONS: Patient delay was considerable in individuals with colorectal cancer in China. Factors associated with patient delay are complex in Chinese culture. To shorten patient delay, culturally sensitive interventions may be required to improve knowledge, alleviate cancer stigma, enhance self-efficacy to seek medical attention, and promote positive help-seeking behaviors.

Adaptation and psychometric evaluation of the Stoma-QOL questionnaire among Chinese rectal cancer patients with colostomy.

AIM: The purpose of this study was to translate the Stoma-quality of life into Chinese and evaluate its psychometric properties in Chinese patients. BACKGROUND: Quality of life is an important issue for patients with colostomy, and its appropriate and precise measurement is beneficial to promoting better care. The Stoma-quality of life questionnaire has been widely used; however, the validity and reliability of its Chinese version has not been determined. DESIGN: A cross-sectional validation study was conducted. METHODS: We translated the Stoma-quality of life into Chinese using standardized methods. Then it was psychometrically tested on a convenience sample of 513 patients with colostomy. Construct validity was evaluated via exploratory factor analysis and confirmatory factor analysis. Reliability was measured with Cronbach's alpha and the split-half Spearman-Brown coefficient. RESULTS: The content validity, the Cronbach's α coefficient and the Spearman-Brown split-half reliability coefficient indicated adequate validity and reliability. The exploratory factor analysis yielded four common factors, and the cumulative variance contribution rate was 67.5%. Moreover, the confirmatory factor analysis showed a good model fit. CONCLUSION: This study confirmed that the Chinese version of Stoma-quality of life is an effective and reliable measurement for evaluating the quality of life of patients with colostomy.

Public awareness of colorectal cancer in the Chinese population: An online cross-sectional survey study.

OBJECTIVES: To investigate public awareness of colorectal cancer (three components: total knowledge, confidence and anticipated delay) in the Chinese population, to explore factors associated with total knowledge and to elucidate relationships among three components of public awareness of colorectal cancer. METHODS: We recruited 562 adult Chinese participants with no history of colorectal cancer between March and May 2020 by convenience sampling method. Data were collected online using a self-designed demographic questionnaire and a simplified Chinese version of the Bowel Cancer Awareness Measure. Univariate analysis and multivariate linear regression were applied. RESULTS: The mean score for total knowledge was 10.56 (SD: 5.89). Over half of the participants (58.2%) lacked confidence about detecting warning signs. For 42.7% of participants, the anticipated delay was not within the acceptable range (2 weeks). Totally eight demographic variables were identified as significant predictors of total knowledge, accounting for 36.2% of the variance. Total knowledge was positively correlated with confidence (r = 0.126, p < 0.01) and negatively associated with anticipated delay (F = 8.891, p < 0.01). CONCLUSION: Public awareness of colorectal cancer was low in the Chinese population. Hence, educational interventions targeted for improving knowledge, enhancing individuals' confidence in detecting symptoms and reducing barriers to seeking medical help may be urgently required.

Quality of Life and Its Influencing Factors Among Chinese Patients With Permanent Colostomy in the Early Postoperative Stage: A Longitudinal Study.

BACKGROUND: Colorectal cancer is one of the most common cancers worldwide. Although colostomies are necessary for disease treatment, they unavoidably affect patient quality of life (QOL), especially in the early postoperative stage. OBJECTIVE: The aim of this study was to investigate the dynamic changes and factors influencing QOL among Chinese patients with permanent colostomy. METHODS: We investigated 74 patients before discharge and at 1 and 3 months after discharge. Instruments included the Quality of Life Questionnaire for People With Ostomy-Chinese version, Stoma Self-efficacy Scale, Stoma Self-care Scale-Early Stage Version, and a demographic and stoma-related information questionnaire. RESULTS: The average QOL increased significantly after discharge (P < .01). Multivariate linear regression showed that the influencing factor of QOL was self-efficacy (before discharge, explained 22.9% of the variance); self-efficacy, truth-telling, average time of stoma care, communicating with friends with colostomy, and family relationship (1 month after discharge, explained 48.8% of the variance); and self-efficacy, body image loss, and participating in activities of patients with colostomy (3 months after discharge, explained 85.2% of the variance). CONCLUSIONS: Clinicians need to give attention to improving the QOL of colostomy patients especially 1 month after discharge. Interventions aimed at improving self-efficacy, preoperative education regarding the surgery, colostomy care ability, family relationship, stoma self-acceptance, and involvement in activities of friends with colostomy should be considered to improve QOL among Chinese patients in this setting. IMPLICATIONS FOR PRACTICE: Transitional care should be provided for colostomy patients especially 1 month after discharge. Interventions should focus on enhancing self-efficacy, stoma self-management, and social-environmental support.

Assessment of defecation function after sphincter-saving resection for mid to low rectal cancer: A cross-sectional study.

PURPOSE: Patients with mid-to low-rectal cancer can have various dysfunctions of defecation after sphincter-saving resection. Defecation dysfunction can manifest as incontinence, urgency, or frequent bowel movements, and is called low anterior resection syndrome (LARS). This study aimed to examine LARS score and objective anorectal function indices in Chinese patients receiving sphincter-saving surgery for mid-to low-rectal cancer. METHOD: This was a single-center cross-sectional study of patients undergoing sphincter-saving resection for low- or mid-rectal cancer and had restoration of trans-anal defecation for at least 1 month seen between January 2019 and June 2020. Patients completed a questionnaire regarding clinical characteristics, and Low Anterior Resection Syndrome (LARS) score and high-resolution anorectal manometry (HR-ARM) were used to assess defecation function. Multivariable analysis was used to identify variables significantly associated with defecation dysfunction. RESULTS: 146 patients completed and returned the questionnaires. 25 healthy adults also participated as control group for the anorectal manometry. Approximately 76% of patients developed LARS after surgery, of which 35.6% had major LARS. In these patients, anorectal manometry indices including initial rectal sensory capacity and rectal fecal sensory capacity, were significantly lower than normal. Logistic regression analysis showed that preoperative chemo-radiotherapy and the tumor inferior margins being close to the dentate line, especially 2-5 cm, were independent risk factors for defecation dysfunction after surgery. CONCLUSIONS: Defecation dysfunction is a frequent occurrence after sphincter-saving resection for mid- and low-rectal cancer. Preoperative chemo-radiotherapy and a shorter tumor inferior margins distance to the dentate line are independent factors for defecation dysfunction.

Immediate postoperative experiences before discharge among patients with rectal cancer and a permanent colostomy: A qualitative study.

PURPOSE: Patients with rectal cancer with a permanent colostomy often have issues in physical, psychological and social domains. Since discharge is an important transition period, the patient experience at that time is worthy of attention. The aim of this study was to explore the immediate postoperative experiences before discharge among patients with rectal cancer and a permanent colostomy in China. METHODS: A qualitative design was used. Semi-structured interviews were conducted with 18 patients newly living with colostomy in China, who were asked open-ended questions about their postoperative experience. The thematic analysis approach was used to analyze the data. RESULTS: Four themes and twelve sub-themes were identified from the interviews: (1) psychological reactions (stoma self-acceptance, negative emotion and social isolation), (2) daily life concern (daily life misunderstandings, sexual life compromise and work restriction), (3) stoma care consideration (strong stoma self-care willingness, decreased stoma self-care confidence and access to high-quality stoma care), and (4) support from others (enterostomal nurses, family members and stoma friends). CONCLUSION: Colostomy patients experience various obstacles in physiological, psychological, and societal aspect. Nurses should provide effective discharge guidance to correct misunderstandings about the stoma, refer patients to psychological care, and promote transitional care.

A randomized trial of negative pressure wound therapy technology combined with intermittent instillation in the treatment of neck anastomotic leakage after esophageal cancer surgery.

BACKGROUND: This study aimed to examine the effects of applying the negative pressure wound therapy (NPWT) combined with intermittent instillation (NPWTi) in patients with cervical anastomotic leakage (AL) after esophageal cancer surgery. METHODS: From July 2019 to June 2021, 64 patients undergoing AL after esophageal cancer surgery were selected from our Hospital's Thoracic Department, and randomly allocated to the conventional nursing group (20 patients), the hospital central NPWTi group (23 patients), and the portable NPWTi group (21 patients). The hospital central NPWTi group was treated with central negative pressure combined with intermittent instillation, and the portable NPWTi group was treated with portable negative pressure combined with intermittent instillation. Indicators of fistula healing, healing days, treatment costs, comfort, and nursing satisfaction were examined in each group. RESULTS: The fistula healing rate, healing days, nursing satisfaction, and comfort level of the hospital central NPWTi group and the portable NPWTi group were better than those of the conventional nursing group (P<0.05). There was no difference in the fistula healing rates and healing days between the hospital central NPWTi group, and the portable NPWTi group (P>0.05). The treatment costs of the hospital central NPWTi group were lower than those of the portable NPWTi group (P<0.05). CONCLUSIONS: Negative pressure treatment technology combined with the intermittent instillation of the neck anastomotic fistula improved the fistula microenvironment, strengthened the sterilization effect, drained the leachate effectively, shortened the fistula healing time, improved the fistula cure rate, and increased patients' satisfaction with nursing. In relation to the negative pressure source, there was no difference in the therapeutic effects of hospital central NPWTi compared to the portable negative pressure meter, but the hospital central NPWTi treatment costs were lower and patients' acceptance of NPWT instillation was higher. Thus, central NPWT instillation treatment is worthy of promotion. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2100052240.

Psychosocial behaviour reactions, psychosocial needs, anxiety and depression among patients with rectal cancer before and after colostomy surgery: A longitudinal study.

AIMS AND OBJECTIVES: To compare the differences in psychosocial behaviour reactions, psychosocial needs, anxiety and depression before and after colostomy surgery and to explore the predictors of psychosocial behaviour reactions. BACKGROUND: Colorectal cancer is increasing worldwide. Abdominoperineal resection accompanied by permanent colostomy can cause complicated psychosocial reactions and needs. However, colostomy patients' trajectories of psychosocial adjustment at different time points must be discussed. DESIGN: A longitudinal study. METHODS: Using a convenience sampling method, 67 patients planning to undergo colostomy surgery were recruited from a tertiary cancer centre in southern China from January 2013-January 2014. Data collection consisted of two phases, conducted 1-2 days before surgery and 1-2 days prior to discharge. The Ostomy Psychosocial Behaviour Reaction Questionnaire, the Ostomy Psychosocial Needs Questionnaire, the Hospital Anxiety and Depression Scale and a self-designed demographic questionnaire were used to collect data. STROBE guidelines were followed. RESULTS: The participants had a moderate level of psychosocial behaviour reactions, a deep and wide range of psychosocial needs and a high incidence of anxiety and depression before and after surgery. Anxiety before surgery was significantly higher than that after surgery. Psychosocial needs and anxiety were significant predictors of psychosocial behaviour reactions. CONCLUSIONS: Patients' anxiety was alleviated after surgery. The combination of ascertaining and meeting various psychosocial needs and managing negative emotions was helpful in alleviating patients' stress responses before and after surgery. RELEVANCE TO CLINICAL PRACTICE: An increased focus on the relationships among psychosocial behaviour reactions, psychosocial needs, anxiety and depression at different time points in colostomy patients is necessary for future research and practice.

Stigma and its influencing factors among Chinese patients with stoma.

BACKGROUND: Although stomas are necessary for disease treatment, they unavoidably affect patients' lives from physical, psychological, social, spiritual, and familial perspectives and contribute to feelings of embarrassment and shame. This study explored the current status and factors influencing stigma among Chinese patients with stoma. METHODS: A total of 209 patients with stoma at the stoma clinic of a tertiary cancer centre in Guangzhou, China, were recruited and investigated by using the Social Impact Scale, the Coping Self-Efficacy Scale, the State Self-Esteem Scale, and a demographic questionnaire. Multivariate linear regression was used to identify the factors influencing stigma. RESULTS: The mean Social Impact Scale score was 69.65 ± 13.18, which represents a moderate effect; specifically, 44% of the patients experienced high levels of stigma. Stoma patients with the following characteristics had high levels of stigma: young, low coping self-efficacy, low stoma acceptance by one's spouse or other family members, poor perceived body image, stool leakage, and no experience of participating in activities with other stoma patients. CONCLUSIONS: Medical staff members should pay more attention to stigma in stoma patients. Coping self-efficacy, family members' acceptance of the stoma, and participation in activities with other stoma patients are influencing factors that protect these patients against stigma, whereas body image loss and stool leakage place them at higher risk for stigma. Interventions aimed at improving protective factors and decreasing risk factors should be considered to reduce the level of stigma in patients with stoma.

The preoperative reaction and decision-making process regarding colostomy surgery among Chinese rectal cancer patients.

PURPOSE: Patients with rectal cancer have issues in adjusting to their permanent colostomy after surgery, and support is required to help them resume normal life. However, few studies have explored the experience and factors that affect a patient's decision-making and maladjustment prior to colostomy surgery. The aim of this study was to explore the experience of rectal cancer patients who have to undergo colostomy surgery. METHOD: A descriptive, qualitative design was used. We studied a purposive sample of 18 patients who had received a diagnosis of primary rectal cancer and were expecting permanent colostomy surgery. The thematic analysis approach was used to analyze the data collected using semi-structured, open-ended questions. RESULTS: The overriding theme that emerged was 'stoma dilemma: a hard decision-making process'. From this main theme, three themes were derived: the resistance stage, the hesitation stage, and the acquiescence stage. CONCLUSION: It is hard for preoperative rectal patients to choose to undergo stoma surgery or a sphincter-saving operation. From the initial stage of definitive diagnosis to the final consent to stoma surgery, most patients experience the resistance and hesitation stages before reaching the acquiescence stage. Arriving at a decision is a process that nurses can facilitate by eliminating unnecessary misunderstanding surrounding colostomy surgery and by fully respecting patients' right to choose at the various stages.

Choline and betaine intake and colorectal cancer risk in Chinese population: a case-control study.

BACKGROUND: Few studies have examined the association of choline and betaine intake with colorectal cancer risk, although they might play an important role in colorectal cancer development because of their role as methyl donors. The aim of this study was to examine the relationship between consumption of choline and betaine and colorectal cancer risk in a Chinese population. METHODOLOGY/PRINCIPAL FINDINGS: A case-control study was conducted between July 2010 and December 2013 in Guangzhou, China. Eight hundred and ninety consecutively recruited colorectal cancer cases were frequency matched to 890 controls by age (5-year interval) and sex. Dietary information was assessed with a validated food frequency questionnaire by face-to-face interviews. The logistic regression model was used to estimate multivariate odds ratios (ORs) and 95% confidence intervals (CIs). Total choline intake was inversely associated with colorectal cancer risk after adjustment for various lifestyle and dietary factors. The multivariate-adjusted OR was 0.54 (95%CI = 0.37-0.80, Ptrend <0.01) comparing the highest with the lowest quartile. No significant associations were observed for betaine or total choline+betaine intakes. For choline-containing compounds, lower colorectal cancer risk was associated with higher intakes of choline from phosphatidylcholine, glycerophosphocholine and sphingomyelin but not for free choline and phosphocholine. The inverse association of total choline intake with colorectal cancer risk was observed in both men and women, colon and rectal cancer. These inverse associations were not modified by folate intake. CONCLUSIONS: These results indicate that high intake of total choline is associated with a lower risk of colorectal cancer.

The prevalence and correlates of symptom distress and quality of life in Chinese oesophageal cancer patients undergoing chemotherapy after radical oesophagectomy.

PURPOSE: The current study was designed to describe the symptom distress and quality of life (QoL) in Chinese oesophageal cancer patients undergoing chemotherapy after radical oesophagectomy and to identify the factors that influenced symptom distress and the relationship between symptom distress and QoL. METHODS: The sample consisted of 102 oesophageal cancer patients undergoing chemotherapy after radical oesophagectomy. The patients completed the Chinese versions of the M.D. Anderson Symptom Inventory (MDASI, an instrument that measures symptom distress), the Hospital Anxiety and Depression Scale (HADS), the Medical Coping Modes Questionnaire (MCMQ) and the Functional Assessment of Cancer Treatment-General (FACT-G, an instrument that measures QoL). RESULTS: The symptoms and symptom interference scores of the patients in the current research were 3.62 (SD 1.66) and 2.94 (SD 1.76), respectively. Occupation after illness, anxiety, types of surgery, whether chemotherapy was on schedule and confrontation coping strategies were factors that influenced symptom distress. There was a negative relationship between symptom distress and QoL scores. CONCLUSION: Oesophageal cancer patients receiving chemotherapy suffer many limitations due to symptom distress and disruptions in their QoL. Oesophageal cancer patients should be assessed regularly and should be supported on an ongoing basis.

Psychometric Evaluation of the Ostomy Adjustment Scale in Chinese Cancer Patients With Colostomies.

BACKGROUND: The Ostomy Adjustment Scale (OAS) has been widely used to measure the adjustment to an ostomy. Although the instrument had been used among subjects from various backgrounds, psychometric properties had never been evaluated. OBJECTIVES: The primary aim of this study was to test the psychometric properties of the OAS among Chinese colostomy patients, and the secondary aim was to examine the predictors of colostomy adjustment. METHODS: The translated OAS was tested using a convenience sample of 207 colostomy patients from a university-affiliated cancer center in China. RESULTS: The content validity of the OAS was 0.91. Four items were removed during the process of validity and reliability testing. The final Chinese version of the OAS consisted of 30 items (OAS-C-30) with 4 subscales as follows: negative affect, normal functioning, therapy attitude, and life worry. The Cronbach's α, the intraclass correlation, and a split-half Spearman-Brown coefficient for the total scale were 0.915, 0.902 and 0.871, respectively. Multiple linear regression analysis showed that stoma self-efficacy, stoma acceptance, excessive aerofluxus, constipation, family relationship, and body image loss were the predictors of adjustment among Chinese colostomy patients. CONCLUSION: The OAS-C-30 has been proven to be a valid and reliable measure to assess the adjustment among colostomy patients. IMPLICATIONS FOR PRACTICE: The OAS-C-30 is a useful instrument to assess and monitor the level of adjustment among patients with permanent colostomies. The identified predictor variables for adjustment also provide insights to clinicians to assist them in planning interventions to facilitate the adjustment of colostomy patients.

The influence of demographics, psychological factors and self-efficacy on symptom distress in colorectal cancer patients undergoing post-surgical adjuvant chemotherapy.

PURPOSE: To explore the influence of self-efficacy and demographic, disease-related, and psychological factors on symptom distress among Chinese colorectal cancer patients receiving postoperative adjuvant chemotherapy. METHODS: Two-hundred and fifty-two colorectal cancer patients who had undergone postoperative adjuvant chemotherapy completed Chinese versions of M. D. Anderson Symptom Inventory (MDASI-GI), Stanford Inventory of Cancer Patient Adjustment (SICPA), and Hospital Anxiety and Depression Scale (HADS). Associations between patients' self-efficacy and demographic, disease-related, psychological factors and symptom distress were examined. RESULTS: Patients' overall symptom distress level was mild; MDASI median subscale scores showed mild symptom severity and symptom interference. Anxiety and depression were positively associated with symptom distress. Multivariable analysis showed that more severe symptoms were associated with age ≥60 years, female gender, suburban residence, body mass index <18.5, and stage III cancer. Age ≥60 years, female gender, marital status of single or divorced, and suburban residence were associated with greater symptom interference with daily activities. Greater self-efficacy was associated with milder symptoms severity and less symptom interference with daily life. After adjusting for confounders, patients with higher SICPA scores had less symptom distress. CONCLUSIONS: Self-efficacy is strongly associated with reduced symptom severity and symptom interference with daily life in CRC patients. Symptom severity is associated with age >60 years, female gender, body mass index <18.5, suburban residence and stage III disease. Nurse-administered self-efficacy interventions may help to improve self-efficacy and reduce symptom distress.

Dietary fiber and fiber fraction intakes and colorectal cancer risk in Chinese adults.

Few studies have been conducted in Chinese adults to investigate the effect of fiber intake on colorectal cancer risk. The present study aimed to examine the associations of dietary fiber and fiber fraction intakes with colorectal cancer risk in Chinese adults. A total of 613 cases with colorectal cancer were consecutively recruited between July 2010 and October 2012 and frequency matched to 613 controls by age (5-yr interval) and gender. Dietary information was collected through a validated food frequency questionnaire by face-to-face interviews. Multivariate logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) after adjustment for potential confounders. Total dietary fiber and fiber fraction intakes were found to be inversely associated with colorectal cancer risk. Compared with the lowest quartile, the adjusted ORs (95% CIs) for the highest quartile were 0.38 (0.27-0.55) for total dietary fiber, 0.45 (0.32-0.64) for vegetable fiber, and 0.41 (0.28-0.58) for fruit fiber, respectively. In addition, no significant association was found between soy fiber intake and colorectal cancer risk. This study showed that a high intake of dietary fiber, particularly derived from vegetables and fruit, was inversely associated with colorectal cancer risk in Chinese adults.

Patients after colostomy: relationship between quality of life and acceptance of disability and social support.

BACKGROUND: The aim of this research was to explore quality of life (QOL) and acceptance of disability and social support of colostomy patients as well as the relationship between these factors. METHODS: A descriptive, correlational study was conducted using four scales: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and European Organization for Research and Treatment of Cancer Colorectal Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-CR38) scales, the Acceptance of Disability Scale (ADS), and the Social Relational Quality Scale (SRQS). A convenience sample of 111 colostomy patients from four hospitals in Guangzhou who underwent colostomy operation at least one month prior to the study and who visited the stoma clinic or association from August 2011 to February 2012 was evaluated for inclusion in the study. All statistical analyses were performed using SPSS 17.0 software (SPSS Inc., Chicago, IL, USA). RESULTS: The patients' general health status was better than the reference level recommended by European Organization for Research and Treatment of Cancer, and the overall ADS score was average. The SRQS score was similar to that found in a Hong Kong study. The general health status and dimensions of QOL were significantly correlated with ADS and all of its dimensions (P < 0.05). The general health status and dimensions of QOL were also significantly correlated with SRQS and all of its dimensions (P < 0.05). CONCLUSIONS: QOL, acceptance of disability, and social relational quality of colostomy patients were closely related. Our results emphasize that patients should work to form rational values and close bonds with families and friends to achieve a better QOL.

Dietary fat, fatty acid intakes and colorectal cancer risk in Chinese adults: a case-control study.

The associations between dietary fat intakes and the risk of colorectal cancer have been examined in many epidemiological studies, but the results have remained inconsistent. This study aimed to examine the associations of total fat and fatty acid intakes with the risk of colorectal cancer in Guangzhou, China. A case-control study was carried out between July 2010 and May 2012 in Guangzhou, China. Four hundred and eighty-nine consecutively recruited colorectal cancer cases were frequency matched to 976 controls by age (5-year interval) and sex. A validated food frequency questionnaire was used to collect dietary information by face-to-face interviews. Multivariate logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs). The total fat intake was not related to the risk of colorectal cancer, with an OR (95% CI) of 0.95 (0.68-1.32) comparing the highest with the lowest quartiles. Intakes of saturated fat, monounsaturated fat, and n-6 polyunsaturated fat were also not associated with the risk of colorectal cancer. However, a significant inverse association was found between total n-3 polyunsaturated fat, α-linolenic acid, and long-chain n-3 polyunsaturated fat consumption and the risk of colorectal cancer. The adjusted ORs of the highest versus the lowest quartile were 0.45 (95% CI=0.32-0.64, Ptrend<0.01) for total n-3 polyunsaturated fat, 0.54 (95% CI=0.38-0.76, Ptrend<0.01) for α-linolenic acid, and 0.58 (95% CI=0.41-0.82, Ptrend<0.01) for long-chain n-3 polyunsaturated fat. This study suggested that total fat, saturated fat, monounsaturated fat, and n-6 polyunsaturated fat intakes were not related to the risk of colorectal cancer. However, increased consumption of n-3 polyunsaturated fat might reduce the risk.

Effects of enterostomal nurse telephone follow-up on postoperative adjustment of discharged colostomy patients.

BACKGROUND: People with a new colostomy encounter many difficulties as they struggle to adjust to their ostomies. Nurse telephone follow-up is a convenient way to ensure continuity of care. There is a paucity of studies testing if nurse telephone follow-up can enhance adjustment of postdischarged colostomy patients. OBJECTIVES: The purpose of this study was to evaluate the effect of enterostomal nurse telephone follow-up on the adjustment levels of discharged colostomy patients. METHODS: This was a randomized controlled trial. Participants (n = 103) who had undergone colostomy operations in China were recruited and randomly assigned to the study or control group. Both the study and control groups received routine discharge care, whereas the study group received 2-3 nurse telephone calls in the follow-up period. The outcome measures included Ostomy Adjustment Scale, Stoma Self-efficacy Scale, satisfaction with care, and stoma complications. RESULTS: Results of this study indicated that participants in the study group had significantly better ostomy adjustment, higher stoma self-efficacy, higher satisfaction with care, and less stoma complications compared with those in the control group. CONCLUSIONS: This study provided evidence to support that enterostomal nurse telephone follow-up can improve patient ostomy adjustment level and other related outcomes. IMPLICATION FOR PRACTICE: Nurse telephone follow-up is an effective intervention to support the adjustment of stoma patients after hospital discharge.

Telephone follow-up for patients returning home with colostomies: views and experiences of patients and enterostomal nurses.

PURPOSE: To explore the views of patients and enterostomal nurses regarding a telephone follow-up program for patients returning home with colostomies. METHODS AND SAMPLE: Semi-structured interviews were conducted with eleven patients who accepted a telephone intervention and seven enterostomal nurses who conducted telephone follow-ups. Qualitative data were analyzed using content analysis. KEY RESULTS: The enterostomal nurses indicated that the telephone follow-up was appreciated and well accepted by the patients. Both the patients and the enterostomal nurses perceived the telephone follow-up as efficient at solving stoma care problems in a timely manner, shortening the process of resuming normal life, and most importantly, providing psychological support. The enterostomal nurses found that telephone follow-up after a patient's hospital discharge was meaningful work. Additional nurse training and measures to overcome communication barriers are required. CONCLUSIONS: All of the patients benefited from the nurse-led telephone follow-up program as part of the continuity of nursing care. The sustainability of the service requires hospital support. Further dissemination of telephone follow-up to other discharged surgical patients might be warranted.

[Relationship between body mass index and colon cancer].

BACKGROUND AND OBJECTIVE: Obesity is associated with increased risk of colorectal cancer. Many studies showed that body mass index (BMI) is related to the incidence of colon cancer. This study was to explore the relationship between BMI and colon cancer in Chinese population and provide evidences for the prevention of colon cancer. METHODS: Clinical data, including BMI, of 707 colon cancer patients and 709 healthy subjects were compared. RESULTS: The mean BMI was significantly higher in colon cancer patients than in healthy subjects [(24.52+/-4.56) kg/m2 vs. (23.75+/-3.14) kg/m2, t=-3.72, P<0.001]. When stratified by sex and age, the BMI was always higher in colon cancer patients than in healthy subjects. Logistic regression analyses showed that BMI was an important risk factor of colon cancer (odds ratio=1.059, 95% confidence interval=1.029-1.090). CONCLUSION: The occurrence of colon cancer in Chinese population is related to BMI.
