African swine fever virus A137R protein inhibits NF-κB activation via suppression of MyD88 signaling in PK15 and 3D4/21 cells in vitro.

African swine fever (ASF) is an infectious disease with high mortality caused by African swine fever virus (ASFV), which poses a great threat to the global swine industry. ASFV has evolved multiple strategies to evade host antiviral innate immunity by perturbing inflammatory responses and interferon production. However, the molecular mechanisms underlying manipulation of inflammatory responses by ASFV proteins are not fully understood. Here, we report that A137R protein of ASFV is a key suppressor of host inflammatory responses. Ectopic expression of ASFV A137R in HEK293T cells significantly inhibited the activation of IL-8 and NF-κB promoters triggered by Sendai virus (SeV), influenza A virus (IAV), or vesicular stomatitis virus (VSV). Accordingly, forced A137R expression caused a significant decrease in the production of several inflammatory cytokines such as IL-8, IL-6 and TNF-α in the cells infected with SeV or IAV. Similar results were obtained from experiments using A137R overexpressing PK15 and 3D4/21 cells infected with SeV or VSV. Furthermore, we observed that A137R impaired the activation of MAPK and NF-κB signaling pathways, as enhanced expression of A137R significantly decreased the phosphorylation of JNK, p38 and p65 respectively upon viral infection (SeV or IAV) and IL-1ß treatment. Mechanistically, we found that A137R interacted with MyD88, and dampened MyD88-mediated activation of MAPK and NF-κB signaling. Together, these findings uncover a critical role of A137R in restraining host inflammatory responses, and improve our understanding of complicated mechanisms whereby ASFV evades innate immunity.

STAT3 regulates antiviral immunity by suppressing excessive interferon signaling.

This study identifies interleukin-6 (IL-6)-independent phosphorylation of STAT3 Y705 at the early stage of infection with several viruses, including influenza A virus (IAV). Such activation of STAT3 is dependent on the retinoic acid-induced gene I/mitochondrial antiviral-signaling protein/spleen tyrosine kinase (RIG-I/MAVS/Syk) axis and critical for antiviral immunity. We generate STAT3Y705F/+ knockin mice that display a remarkably suppressed antiviral response to IAV infection, as evidenced by impaired expression of several antiviral genes, severe lung tissue injury, and poor survival compared with wild-type animals. Mechanistically, STAT3 Y705 phosphorylation restrains IAV pathogenesis by repressing excessive production of interferons (IFNs). Blocking phosphorylation significantly augments the expression of type I and III IFNs, potentiating the virulence of IAV in mice. Importantly, knockout of IFNAR1 or IFNLR1 in STAT3Y705F/+ mice protects the animals from lung injury and reduces viral load. The results indicate that activation of STAT3 by Y705 phosphorylation is vital for establishment of effective antiviral immunity by suppressing excessive IFN signaling induced by viral infection.

Impact of defecation dysfunction on quality of life in mid-low rectal cancer patients following sphincter-sparing surgery.

Objectives: A large proportion of mid-low rectal cancer patients develop low anterior resection syndrome (LARS) after Sphincter-sparing surgery. This study aimed to investigate the effect of low anterior resection syndrome (LARS) on quality of life (QoL) in Chinese rectal cancer patients following sphincter-sparing surgery. Methods: This was a comparative cross-sectional study. Between Jan 2019 to Jun 2020, 146 mid-low rectal cancer patients following sphincter-sparing surgery were enrolled. The low anterior resection syndrome (LARS) score was used to assess bowel dysfunction. According to the LARS score, patients were divided into three levels, no LARS (n â€‹= â€‹34), minor LARS (n â€‹= â€‹60), and major LARS (n â€‹= â€‹52). The Functional Assessment of Cancer Therapy-Colorectal (FACT-C) was used to assess the QoL of the patients. Results: The major LARS group had a significantly shorter level of tumor from the dentate line than the no LARS group. The total FACT-C score of 146 patients was 98.45 â€‹± â€‹17.83. The total FACT-C score and the score of each dimension (physical, emotional, functional dimensions, and colorectal cancer subscale) were significantly different between the minor LARS and major LARS groups, as well as between the no LARS and major LARS groups. Subgroups analyses of the FACT-C score stratified by each item in the LARS scales showed that except for flatus incontinence, patients with different frequencies of other symptoms (bowel frequency, liquid stool incontinence, liquid stool incontinence, stool clustering, urgent bowel movement) had a significantly different total score of FACT (all P â€‹< â€‹0.01). Conclusions: The LARS had a significant impact on the QoL in Chinese mid-low rectal cancer patients following sphincter-sparing surgery, especially in patients with major LARS.

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.

Successful management of exudate and odor using a pouch system in a patient with malignant facial wound: A case report.

Malignant fungating wounds are associated with heavy exudate and malodor, and can thus have a devastating impact on the physical, psychological, and functional health of patients at the end of life. Management is typically limited to the use of more absorbent dressings and frequent changing of dressings. However, this method is associated with a large amount of time needed for wound care, and does not always resolve the problem of malodor. Herein, we report the use of an inexpensive ostomy pouch to manage facial fungating wounds caused by maxillary gingival carcinoma. The pouches are adhered to the skin, and collect a large amount of malodorous exudate for days without leaking. Fewer dressing changes and the absence of malodor result in an improved quality of life for the patient and family.

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.

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.

An early report of a screening program for colorectal cancer in Guangzhou, China.

BACKGROUND: We launched a screening program for colorectal cancer (CRC) in Yuexiu District, Guangzhou, China, in 2014. Here we aimed to report the early results of the program and evaluate the benefits of a screening questionnaire. METHODS: Residents aged between 50 and 74 were eligible for the screening. A questionnaire and two consecutive fecal immunological tests (FITs) were used as primary screening methods. Subjects who were positive for any of the two tests were referred for further examination with colonoscopy. Neoplasms were removed either colonoscopically or by colectomy. Atypical adenoma and CRC were defined as advanced neoplasms. RESULTS: A total of 6,971 residents in Dadong Street, Yuexiu District were screened with a questionnaire, and among them, 5,343 underwent at least one FIT. Four thousand and two hundred eleven (60.4%) were female, and 2,760 (39.6%) were male, with a median age of 62.0 years. Questionnaire and FITs identified 1,219 candidates for further examination with colonoscopy, among whom only 647 (53.1%) comply. As of this writing, 623 colonoscopy results were obtained, among which 270 (43.3%) had positive findings. The adenoma detection rate (ADR) was 43.3% (270/623). The ADR was 43.3% (270/623). Of the 270 patients, 10 (3.07%) had CRC, 81 (30.0%) had advanced adenoma, 178 had low-grade adenoma or other benign polyps, one had carcinoid. Except for three advanced CRC, all neoplasms detected were benign or in an early stage. CONCLUSIONS: Our screening program help identified patients with colonic neoplasms at an early stage, precluding them from developing into the malignant disease. The addition of the questionnaire significantly increased the sensitivity of primary screening, while also decreasing the specificity. Long-term results should evaluate the social and economic benefits of this program.

The effect of biofeedback training on intestinal function among patients with middle and low rectal cancer: a randomized controlled study.

BACKGROUND: To evaluate the effect of biofeedback on intestinal function among patients with middle and low rectal cancer. METHODS: Using a randomized controlled trial design, 109 patients with middle and low rectal cancer indicated to have preoperative radiochemotherapy, anterior resection of the rectum, and preventive stoma were randomly divided into three groups: the blank control group, the pelvic floor muscle exercise group, and the biofeedback training group. A 16-month intervention and longitudinal follow-up study was conducted, and a questionnaire on intestinal function by the Memorial Sloan-Kettering Cancer Center (MSKCC) was adopted into a Chinese version to evaluate patients' intestinal function situation. RESULTS: The intestinal function of the biofeedback training group was better than the blank control group and pelvic floor muscle exercise group. The total score of intestinal function and the scores of each dimension were statistically significant (P<0.05). CONCLUSIONS: Biofeedback training could significantly improve the intestinal function of patients with middle and low rectal cancer, promote its recovery, and is thus worthy of clinical application.

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.

Physical and Psychological Predictors of Quality of Life in Chinese Colorectal Cancer Patients During Chemotherapy.

BACKGROUND: Maintaining quality of life (QOL) during chemotherapy is a critical aspect of cancer treatment. Instruments have been developed to assess symptom distress, self-efficacy, anxiety, depression, and other factors impacting QOL during cancer treatment, but Chinese versions have become available only recently. OBJECTIVE: The aim of this study was to identify factors predictive of QOL during chemotherapy in Chinese colorectal cancer (CRC) patients. METHODS: Patients completed Chinese versions of the Hospital Anxiety and Depression Scale, MD Anderson Symptom Inventory (a measure of symptom distress), Stanford Inventory of Cancer Patient Adjustment (a measure of self-efficacy), and Functional Assessment of Cancer Treatment-General (a measure of QOL) before and after 3 and 6 months of chemotherapy. RESULTS: Of 152 consecutive CRC patients (men/women, 98/54; mean age, 53.3 ± 11.3 years, 25-75 years; stage II/III, 59/93), 121 completed all questionnaires (79.6%). Self-efficacy dimensions "communication," "activity management," "personal management," and "affective management" improved progressively over 6 months (all P < .05). Fatigue, nausea, lack of appetite, disturbed sleep, and vomiting peaked at 3 months and declined thereafter (P < .05). Patients who are younger than 60 years, are male, and with stage II CRC exhibited higher 3- and 6-month QOL scores (all P < .05). Multiple regression identified self-efficacy, anxiety, and symptom distress as independent predictors of QOL at 6 months. CONCLUSIONS: Enhanced self-efficacy, reduced symptom distress, and lower general anxiety would improve QOL during chemotherapy for CRC patients.These instruments can help identify CRC patients at risk of low QOL for additional psychotherapy or specific treatment modifications.

Factors influencing adjustment to a colostomy in Chinese patients: a cross-sectional study.

PURPOSE: We evaluated persons living with a colostomy in order to characterize and describe relationships among adjustment, self-care ability, and social support. SUBJECTS AND SETTING: One hundred twenty-nine colostomy patients from 5 hospitals in Guangzhou, capital city of the Guangdong province, were recruited by convenience sampling. INSTRUMENTS: Cross-sectional data were collected from a survey that included demographic and pertinent clinical data related to their ostomy. The survey also incorporated Chinese language versions of the Ostomy Adjustment Scale, Exercise of Self-Care Agency Scale, and Perceived Social Support Scale. These scales were used to measure the levels and degrees of adjustment, self-care ability, and social support of colostomy patients. METHODS: Respondents completed the survey during outpatient clinics visit after creation of a colostomy. RESULTS: Scores from the Ostomy Adjustment Scale revealed that 96.9% of colostomy patients reported low to moderate adjustment (128.6 ± 19.38) to their stoma. Self-care ability and social support of patients were positively correlated with the adjustment level (R = 0.33, R = 0.21). Several factors, including being a housewife, paying medical expense by oneself, inability to manage the ostomy without assistance, and not participating in an ostomy support group, were associated with a lower level of adjustment (P < .05). Worries about odor and antipathy toward the ostomy significantly contributed to lower levels of adjustment to the stoma (P < .01). CONCLUSION: Overall adjustment to a colostomy was moderate. Self-care ability and social support associated with having a colostomy positively influenced adjustment. Adjustment was also influenced by occupation, health insurance provider, and ability to care for the stoma without requiring assistance.
