Self-perceived burden and its associations with health-related quality of life among urologic cancer patients

Stigma and related influencing factors in brain cancer patients: a cross-sectional study and parallel mediation analysis

PURPOSE

Patients with brain cancer and painful symptoms of the disease experience heavy pressure and negative inner experiences, leading to a sense of stigma. Therefore, this study assessed the level of stigma in patients with brain cancer and analyzed the risk factors for stigma to analyze the underlying relationships among depression, social support, low self-esteem, and stigma.

METHODS

Patients completed the Social Impact Scale, Self-rating Depression Scale, Rosenberg Self-Esteem Scale, Herth Hope Index, Social Support Rating Scale, and Self-Perceived Burden Scale. Multiple linear regression analysis was used to identify factors independently associated with stigma. Parallel mediation analysis was used to evaluate the mediating role of the relationship between psychoemotional factors and stigma.

RESULTS

A multivariate linear regression analysis demonstrated significant associations between age (β =  - 0.189, P = 0.002), treatment (β = 0.184, P = 0.003), self-esteem (β =  - 0.128, P = 0.046), depression (β = 0.273, P < 0.001), hope (β =  - 0.217, P = 0.003), and self-perceived burden (β = 0.260, P < 0.001) with brain cancer. It was observed that the social support received by brain cancer patients directly impacted their stigma (total effect, - 0.851, P = 0.001). Additionally, this relationship was influenced by depression and self-esteem through two distinct pathways.

CONCLUSION

Increased stigma among brain cancer patients was found to be associated with severe depression, feelings of inferiority, diminished hope, and a heavy perceived burden. The structural equation modeling (SEM) revealed that social support negatively influenced stigma through depression and self-esteem. It is imperative to grasp patients' inner needs, implement psychological interventions, and cultivate a cancer-friendly social environment to prevent stigmatization and discrimination based on their patient status.

Factors influencing health-related quality of life in patients with bladder or kidney cancer: a prospective cohort study of the impact of nutritional status and frailty phenotype

PURPOSE

This study aimed to investigate the impact of nutritional status and frailty phenotype and the predictors of temporal changes on health-related quality of life (HRQoL) of patients with bladder or kidney cancer.

METHODS

Frailty phenotype, Patient-Generated Subjective Global Assessment, and Quality-of-life questionnaire Core-30 were applied twice to patients diagnosed with bladder or kidney cancer. Patients also completed a sociodemographic questionnaire, and clinical data were collected from records.

RESULTS

Sixty-two individuals completed the study, mostly male, with a mean age of 62.5 (± 11.4) years. The median time of follow-up was 14.5 months. Role functioning, emotional functioning, and fatigue improved over time (p < 0.05). The factors that negatively affected the long-term quality of life summary score were being female, malnourished, pre-frail and frail, cancer treatment, performance status, and lower income. Using the multivariate model, being malnourished (β =  - 7.25; 95% CI, - 10.78 to - 3.71; p < 0.001), frail (β =  - 7.25; 95% CI, - 13.39 to - 1.11; p = 0.021), and each one-point increase in performance status (β =  - 6.9; 95% CI, - 9.54 to - 4.26; p < 0.001), were the ones that most negatively impacted the HRQoL between the two assessments.

CONCLUSION

This study confirmed that frailty, nutritional status, and performance status are the main predictors of HRQoL of patients with bladder or kidney cancer over time.

IMPLICATIONS FOR CANCER SURVIVORS

These findings may be the first step towards highlighting the importance of preventing malnutrition and frailty, in favor of a better long-term QoL for cancer patients.

Self-Efficacy's Mediating Role in the Relationship Between Self-Perceived Burden and Health-Related Quality of Life Among Older-Adult Inpatients in China: A Cross-Sectional Study

Purpose

This study investigated the current state of self-efficacy and the association between self-perceived burden (SPB) and health-related quality of life (HRQoL) among Chinese older-adult inpatients.

Methods

A cross-sectional study was conducted using convenience sampling to survey Chinese older-adult inpatients. Data regarding demographic characteristics, self-efficacy, SPB, and HRQoL were collected. Pearson's correlation analysis was used to examine the correlations among the research variables. SPSS® Statistics V26.0, and SPSS® PROCESS Macro Model 4 were used to analyze the available data. The bootstrap method was used to analyze the mediating role of self-efficacy.

Results

Survey participants included 514 older-adult inpatients, with a mean age of 72.28±5.58 years. Self-efficacy (r=0.471, p<0.01) was positively correlated with HRQoL, whereas self-efficacy (r=-0.891, p<0.01) and HRQoL (r=-0.516, p<0.01) were negatively correlated with SPB. The mediating effect analysis revealed that self-efficacy either completely or partially mediated the effect of SPB on HRQoL, with the indirect effect accounting for 30.2% of the total.

Conclusion

This study provides a mediating model suggesting that SPB exerts both direct and indirect effects on the HRQoL of older-adult inpatients through self-efficacy.

A scoping literature review of factors influencing cancer patients' self-perceived burden

PURPOSE

A cancer diagnosis disrupts the peaceful lives and plans of patients and even their caregivers, and patients can easily feel burdened when they are being cared for by others. However, the influencing factors of self-perceived burden (SPB) have not been summarized, and related research is still in its infancy. This review explores factors related to the SPB of cancer patients and identifies future research directions.

METHOD

A systematic search, including trolling through six electronic databases, was conducted to identity articles published in English and Chinese from January 2003 to April 2022, using key terms related to cancer patients' burden on others; a manual search was also performed on the articles' reference lists.

RESULTS

Thirty-three articles were identified. The content was described into three groups: patient-related factors, caregiver-related factors, and family-related (financial) factors. Despite the heterogeneity, patients' physical/disease factors, psychological factors, social factors, caregiver type, quality of care provided, caregiver physical and psychological status, and financial factors were all correlated with SPB.

CONCLUSIONS

This literature review shows that SPB imposes a huge burden on cancer patients, and that SPB in cancer patients is influenced by patient-related factors, caregiver-related factors, and family factors. These influencing factors directly or indirectly affect SPB. In addition, SPB is complex and studies related to its factors deserve a further detailed analysis based on the actual situation of the patients in order to make the results more accurate and relevant.

Post-surgery financial toxicity and its influencing factors in colorectal cancer care: A cross-sectional study

PURPOSE

This study aimed to investigate the influence factors of financial toxicity experienced by colorectal cancer patients after surgery. The results will provide deep insights for developing effective intervention strategies to address this common issue of colorectal cancer care.

METHODS

In this cross-sectional study, we recruited 213 postoperative patients with colorectal cancer from February 2023 to July 2023 in two major public hospitals. Patients completed the General Information Questionnaire, Comprehensive Scores for Financial Toxicity (COST), Self-perceived Burden Scale (SPBS), Family Resilience Questionnaire (FaREQ), and Social Support Rating Scale (SSRS). A multiple linear regression model was used to investigate the influence factors of financial toxicity.

RESULTS

The mean score of financial toxicity was medium (18.91 ± 7.90) in this study. Financial toxicity score was negatively correlated with self-perceived burden (r = -0.333, P < 0.01) and positively associated with family resilience (r = 0.365, P < 0.01) and social support (r = 0.388, P < 0.01). Via multiple linear regression analysis, we identified seven significant factors associated with financial toxicity, including family income [(95 %CI: 1.075-3.123); P = 0.000], self-perceived burden [(95 %CI: 0.300∼-0.038); P = 0.012], stoma [(95 %CI: 5.309∼-1.682); P = 0.000], social support [(95 %CI:0.058-0.407); P = 0.009], cancer stage [(95 %CI: 2.178∼-0.170); P = 0.022], postoperative duration [(95 %CI: 1.900∼-0.332); P = 0.005], and family resilience [(95 %CI: 0.028-0.203); P = 0.010].

CONCLUSIONS

Financial toxicity was prevalent among postoperative colorectal cancer patients. Additional support and early interventions should be given to high-risk patients, including those with stomas, advanced disease stages, or experiencing longer postoperative duration. Apart from demographic factors, we identified that self-perceived burden, family resilience, and social support were also associated with financial toxicity, providing a new perspective for developing effective strategies against financial toxicity.

Correlations between activation, family adaptation, and self-perceived burden in breast cancer patients with an implanted venous access port: A cross-sectional study

We found that activation and family adaptation on the self-perceived burden of breast cancer patients with an implanted venous access port (IVAP), and to analyze the correlations among these scores. A total of 256 patients completed a general data questionnaire, the Patient Activation Measure (PAM), the Family adaptation and Cohesion Scale II-Chinese version (FACES-II-CV), and the Self-perceived Burden Scale (SPBS). The total scores for activation, family adaptation, and self-perceived burden were 63.31 ± 18.92, 42.72 ± 7.937, and 28.55 ± 7.89, respectively. We analyzed activation and family adaptation were associated with self-perceived burden (P < .05) the patients' self-perceived burden main factors is included Main caregiver, disease stage, complications, Type of health insurance, activation, and family adaptation. The activation, family adaptation, and self-perceived burden of breast cancer patients with an IVAP are closely related, which suggests that clinical workers should consider the patient family to formulate an intervention plan to improve patient activation, and thus reduce the self-perceived burden. For example, hospitals regularly conduct breast cancer health education activities, or invite psychological counselors to provide services to patients.

Revisiting the proven relationship of green leadership, green education, and green finance with sustainable development goal 3 in the context of China: does public health expenditure really mediate the relationship?

How effectively our leaders are trained and prepared for the future is the ultimate success as it helps in achieving sustainable development goals. Simultaneously, education also holds a central position to acknowledge social, environmental, and ethical issues. Besides, healthcare sector is the major subject of discussion when there is a discussion of sustainable development, the reason being its direct linkage with SDG 3 which purely preaches healthcare and well-being. The healthcare sector itself aspires to protect health; however, it is also the highest emitter of pollution that creates vicious cycle. This establishes a greater interest to determine the factors that break the cycle through the sustainable healthcare organizations which is subjected to reduce emissions and protect environment, nature, and society. The study specifically focusing on sustainable development goal 3 intends to examine the collective role of green leadership, green education, and green finance from the perspective of private sector employees. We explore whether these factors are helpful to achieve SDG3 agenda in the presence of mediator, public health expenditure. With the help of PLS-methodology, the study concludes that green leadership and green education are strong indicators of SDG3. Besides, green finance also facilitates economies to find innovative ways through which health and well-being of individuals can be taken care of. The positive and significant mediation effect of public health expenditure indicates that there is a need to dedicate the efforts toward public health expenditures.

Intervention and coping strategies for self-perceived burden of patients with cancer: A systematic review

Objective

Self-perceived burden (SPB) is a painful experience for patients with cancer and their caregivers. However, the intervention and coping strategies for SPB have not been systematically summarized. This work reviews the effects of interventions and coping strategies on SPB.

Methods

A systematic search, including trawling through six electronic databases, was performed to identify the articles published from January 2003 to February 2023, both in English and in Chinese. The key terms related to burden on others, intervention, and coping of patients with cancer were adopted. Manual search was also applied.

Results

Thirty articles were identified. Interventions were presented in three dimensions: physical, psychological, and financial/family. Coping strategies were presented in terms of coping attitudes and behaviors. Interventions such as functional exercise and psychological adjustment can improve SPB in the three dimensions mentioned above and thus alleviate SPB. Patients with different coping styles have different implications for prognosis. In addition, the impact of caregivers on patients and the coping they provided were worthy of attention.

Conclusions

This article reviewed interventions for SPB in patients with cancer and the coping strategies from patients and caregivers. The interventions targeting on SPB can alleviate SPB by improving patients' physical condition, psychological status, and financial/family situation. However, the coping attitudes and behaviors of both patients and caregivers were depending on the individual cognitions and perceptions; different coping strategies produced different outcomes. To achieve improvements in SPB, interventions should incorporate the coping strategies. Appropriate patient-caregiver dyad interventions should be constructed based on the commonalities in coping with SPB.

Self-perceived Burden for People With Life-threatening Illness: A Qualitative Systematic Review

CONTEXT

The perception of being a burden to others is a significant concern for people with life-threatening illness. It is unclear what underpins the concept of "self-perceived burden".

OBJECTIVES

To appraise and integrate primary evidence underpinning the concept of self-perceived burden (SPB) with respect to their informal caregivers among adult patients with life-threatening illness.

METHODS

This is a systematic review and a thematic synthesis of qualitative primary data. MEDLINE, Embase, PsycINFO, CINAHL, and Web of Science were searched in September 2021, supplemented by hand searching of textbooks and web search engines, peer-review journals, and contact with experts. Qualitative studies were included if they provided primary data of adult patients' (with life-limiting illness) SPB toward their informal caregivers. Studies were appraised using the Critical Appraisal Skills Programme checklist.

RESULTS

Nine studies were included, reporting on 219 patients who mostly had advanced life-threatening illness and needed physical assistance for daily activities. SPB is a highly subjective perception contrasting self and/or informal caregivers in the past, present, and future. Patients develop SPB feeling uncertain about caregivers' perceptions and increasing future burden. SPB interacts with other factors of surrounding complex balances (such as care needs, reality, and identity) which would change over time, and patients' reactions to SPB at the sacrifice of their wishes may conversely increase the total suffering.

CONCLUSION

SPB is not a static perception but a fluctuating and complex 'process' based on uncertainty. More diverse understandings and following interventions to achieve a better balance of care should be sought.

Self-perceived burden predicts lower quality of life in advanced cancer patients: the mediating role of existential distress and anxiety

Background

Self-perceived burden (SPB) is an important predictor of quality of life (QoL) in patients with advanced cancer. However, the mechanism how SPB affects patients’ QoL remains unclear. This study aimed to examine the potential mediating roles of existential distress (ED) and anxiety in the relationship between SPB and QoL.

Methods

A multicenter cross-sectional study was conducted. 352 advanced cancer patients were recruited from three hospitals in southeast of China. The Self-perceived Burden Scale, the Existential Distress Scale, the Hospital Anxiety and Depression Scale, and the Quality-of-Life Concerns in the End of Life Questionnaire were adopted to collect data. Hayes’s bootstrapping method was used to analyze the data.

Results

SPB was negatively associated with QoL (P < 0.01). ED and anxiety partially mediated the relationship between SPB and QoL (P < 0.01). Moreover, ED had direct effects on anxiety, and sequentially QoL (P < 0.01). The serial multiple mediation model of SPB accounted for 73.25% of the variance in QoL in advanced cancer patients.

Conclusions

ED and anxiety are important mediating factors between SPB and QoL in advanced cancer patients. To improve patients’ QoL, comprehensive interventions for reducing anxiety and ED are highly recommended in clinical practices.

Systematic review on factors associated with self-perceived burden among cancer patients

INTRODUCTION

Cancer is the leading cause of death in the world. There was a high prevalence of high self-perceived burden (SPB) among cancer patients and this could bring adverse consequences to the physical and mental health of cancer patients, which can lead to suicide if not treated well. This review aims to determine the prevalence of SPB among cancer patients and its risk factors.

METHODS

Published journals before September 2021, from five databases (PubMed, ScienceDirect, Springer, Cochrane, and CNKI) were retrieved according to the keywords. The keywords used included cancer patients, terminally ill patients, cancer, SPB, self-perceived burden, self-burden, self-perceived, factor, predictor, associated factor, determinants, risk factor, prognostic factor, covariate, independent variable, and variable. The quality of the inclusion and exclusion criteria was independently reviewed by three researchers.

RESULTS

Out of 12,712 articles, there are 22 studies met the eligibility criteria. The prevalence of SPB among cancer patients ranged from 73.2 to 100% in Malaysia, China, and Canada. Most of them had moderate SPB. Out of the reported factors, age, gender, marital status, ethnicity, residence, educational level, occupational status, family income, primary caregiver, payment methods, disease-related factors, psychological factors, and physical factors were mostly reported across the studies.

CONCLUSIONS

In conclusion, SPB prevalence is high in cancer patients. Therefore, hospitals, non-governmental organizations, relevant policymakers, and communities can provide special programs for high-risk groups to provide psychological guidance or design corresponding interventions to reduce the SPB level of patients and improve the quality of life.

Self-perceived burden and associated factors in Chinese adult epilepsy patients: A cross-sectional study

Objectives

Epilepsy requires long-term or lifelong treatment, and patients are prone to financial, emotional and psychological burdens that can cause psychological changes during the treatment process. This study aimed to describe the prevalence and associated factors of Self-Perceived Burden (SPB) in Chinese adult epilepsy patients, informing the treatment and nursing of epilepsy.

Methods

A total of 143 adult epilepsy patients were included in this study, and the clinical questionnaire survey was conducted at the Third Xiangya Hospital of Central South University in Hunan, China, from March 2022 to June 2022. The sociodemographic and clinical characteristics of adult epilepsy patients were collected using a self-developed questionnaire, and the data on SPB, stigma and quality of life were collected through the Self-Perceived Burden Scale (SPBS), Kilifi Stigma Scale for Epilepsy (KSSE) and Quality of Life in Epilepsy Inventory-31 (QOLIE-31). Multiple linear regression analysis was used to determine the associated factors influencing SPB in adult epilepsy patients.

Results

The average score of SPBS for the 143 adult epilepsy patients was 30.77 (SD = 9.06), and 89.5% of them had obvious SPB. The results of the univariate analysis showed that residence, monthly household income, duration of epilepsy, type of medication and electroencephalogram finding were associated with SPB (P < 0.05). In Spearman correlation analysis indicated that SPBS score were positively correlated with KSSE score (r = 0.510, P < 0.05) while negatively correlated with QOLIE-31 score (r = −0.506, P < 0.05). Multiple linear regression analysis revealed that factors such as KSSE, type of medication, residence and electroencephalogram finding accounted for 32.8% of the factors influencing SPB in adult epilepsy patients.

Conclusion

89.5% of adult epilepsy patients have varying degrees of SPB, which is associated with high stigma and poor quality of life. Therefore, during the treatment and nursing of adult epilepsy patients, clinical staff should pay attention to the psychological status of patients, help them reduce their psychological burden, and guide them to develop a healthy lifestyle.

The effects of psychosocial and economic factors on the quality of life of patients with end-stage renal disease and their caregivers in Klang Valley, Malaysia: protocol for a mixed-methods study

INTRODUCTION

The number of patients in Malaysia requiring dialysis is expected to rise substantially in the future due to the ageing population and increasing prevalence of diabetes mellitus and hypertension. Hence, more individuals will be expected to adopt the role of caregivers in the future. The upward trend of end-stage renal disease (ESRD) and caregiving for dialysis patients has detrimental consequences for both patients and caregivers in terms of their psychological well-being and quality of life. Despite the current circumstances, there are very few studies in Malaysia that have explored the psychosocial factors, specifically on the economic impact of the management of ESRD.

METHODS AND ANALYSIS

This two-phase sequential explanatory mixed-methods design, incorporating a quantitative design (phase I) and a qualitative study (phase II), is to be conducted in 4 government hospitals and 10 other non-governmental organisations or private dialysis centres within Klang Valley, Malaysia. A cross-sectional survey (phase I) will include 236 patient-caregiver dyads, while focus group discussions (phase II) will include 30 participants. The participants for both phases will be recruited purposively. Descriptive statistics, independent sample t-tests and multiple regression analysis will be used for analyses in phase I, and thematic analysis will be used in phase II.

ETHICS AND DISSEMINATION

Approval for the study has been obtained from the National Medical Research and Ethics Committee (MREC) (NMRR-21-1012-59714) and the Research Ethics Committee of Hospital Canselor Tuanku Muhriz UKM (UKM PPI/111/8/JEP-2021-078) and University of Malaya Medical Centre (MREC ID NO: 2 02 178-10346). Informed consent of the participants will be obtained beforehand, and no personal identifiers will be obtained from the participants to protect their anonymity. The findings will be published in peer-reviewed scientific journals and presented at national or international conferences with minimal anonymised data.

A systematic review of financial toxicity among cancer patients in China

Financial toxicity (FT) has been used to describe patients' whole economic experience that negatively impacts their well-being. FT's adverse effects on patients' health outcomes have been reported by reviews conducted in Western countries. However, these findings may not apply to patients in China. This review aimed to analyze existing data on the measures, prevalence, risk factors, and health-related consequences of FT in China. We searched 10 databases in May 2021 and again in January 2022 using Medical Subject Headings terms and free text. We also searched the reference lists of included articles. Two reviewers independently screened the studies, extracted the data, and assessed the quality of the included studies using the Joanna Briggs Institute Critical Appraisal Checklist. Thirty-one articles describing 30 studies were included in the analysis. Various FT measures were identified, but the number of validated measures was limited. The prevalence of material, psychological, and behavioral FT was 6%–78%, 61%–84%, and 10%–79%, respectively. We identified common risk factors and health-related consequences associated with FT similar to those reported in previous reviews. We also identified several potential risk factors (eg, increased length of hospital stay and larger household size) and consequences (patients' self-perceived burden) in a limited number of studies. Our findings show an urgent need for more data on the prevalence, risk factors, and health-related consequences associated with FT in Chinese cancer patients, and these data must be generated using validated measures.

Illness uncertainty, self-perceived burden and quality of life in patients with chronic myeloid leukaemia: A cross-sectional study

AIMS AND OBJECTIVES

To investigate the relationship between illness uncertainty, self-perceived burden and quality of life and explore the mediating role of self-perceived burden between illness uncertainty and quality of life in patients with chronic myeloid leukaemia.

BACKGROUND

Patients with chronic myeloid leukaemia need long-term, potentially lifelong therapy to control the disease, which affects their quality of life. There is a need for exploring potentially changeable factors to develop interventions. Little is known about the effects of illness uncertainty and self-perceived burden on quality of life in this population.

DESIGN

A cross-sectional study.

METHODS

A convenience sample of 248 patients with chronic myeloid leukaemia was recruited from four university hospitals from February to August 2020. Participants were assessed with the Mishel Uncertainty in Illness Scale, Self-Perceived Burden Scale, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. The STROBE checklist was used to report the results.

RESULTS

Illness uncertainty and self-perceived burden were negatively associated with quality of life in patients with chronic myeloid leukaemia. Self-perceived burden partially mediated the relationship between illness uncertainty and quality of life. The indirect effect was -0.101, accounting for 22.9% of the total effect.

CONCLUSION

The findings revealed the relationship between illness uncertainty, self-perceived burden and quality of life in patients with chronic myeloid leukaemia. Self-perceived burden exerted a mediating role between illness uncertainty and quality of life in this population.

RELEVANCE TO CLINICAL PRACTICE

This study alerts healthcare providers to pay attention to patients' illness uncertainty and self-perceived burden, which can contribute to develop effective interventions to improve the quality of life among patients with chronic myeloid leukaemia in the clinical practice.

Self-perceived burden and influencing factors in patients with cervical cancer administered with radiotherapy

BACKGROUND

Cervical cancer is the fourth commonest malignancy in women around the world. It represents the second most commonly diagnosed cancer in South East Asian women, and an important cancer death cause in women of developing nations. Data collected in 2018 revealed 5690000 cervical cancer cases worldwide, 85% of which occurred in developing countries.

AIM

To assess self-perceived burden (SPB) and related influencing factors in cervical cancer patients undergoing radiotherapy.

METHODS

Patients were prospectively included by convenient sampling at The Fifth Affiliated Hospital of Sun Yat-Sen University, China between March 2018 and March 2019. The survey was completed using a self-designed general information questionnaire, the SPB scale for cancer patients, and the self-care self-efficacy scale, Strategies Used by People to Promote Health, which were delivered to patients with cervical cancer undergoing radiotherapy. Measurement data are expressed as the mean ± SD. Enumeration data are expressed as frequencies or percentages. Caregivers were the spouse, offspring, and other in 46.4, 40.9, and 12.7%, respectively, and the majority were male (59.1%). As for pathological type, 90 and 20 cases had squamous and adenocarcinoma/adenosquamous carcinomas, respectively. Stage IV disease was found in 12 (10.9%) patients.

RESULTS

A total of 115 questionnaires were released, and five patients were excluded for too long evaluation time (n = 2) and the inability to confirm the questionnaire contents (n = 3). Finally, a total of 110 questionnaires were collected. They were aged 31-79 years, with the 40-59 age group being most represented (65.4% of all cases). Most patients were married (91.8%) and an overwhelming number had no religion (92.7%). Total SPB score was 43.13 ± 16.65. SPB was associated with the place of residence, monthly family income, payment method, transfer status, the presence of radiotherapy complications, and the presence of pain (P < 0.05). The SPB and self-care self-efficacy were negatively correlated (P < 0.01). In multivariate analysis, self-care self-efficacy, place of residence, monthly family income, payment method, degree of radiation dermatitis, and radiation proctitis were influencing factors of SPB (P < 0.05).

CONCLUSION

Patients with cervical cancer undergoing radiotherapy often have SPB. Self-care self-efficacy scale, place of residence, monthly family income, payment method, and radiation dermatitis and proctitis are factors independently influencing SPB.
