Experiences of Caregivers with Spouses Receiving Chemotherapy for Colorectal Cancer and their Expectations from Nursing Services

OBJECTIVE

The purpose of this study was to reveal experiences of caregivers whose spouses were receiving chemotherapy for colorectal cancer and their expectations from nursing services.

METHODS

This is a qualitative study. The caregivers were interviewed at their home. Sampling criteria were volunteering to participate in the study, being able to understand Turkish, not having speech or hearing problems and offering care to spouses with primary colorectal cancer. The interviews continued until concepts likely to be responses to research questions repeatedly appeared. Fourteen caregivers with spouses receiving chemotherapy for colorectal cancer comprised the study sample. Data were collected with a descriptive characteristics form and a semi-structured interview at in-depth interviews after making appointments with the caregivers on the phone. The steps followed in the content analysis were coding data, an organization of codes and themes, description of findings and evaluation of findings.

RESULTS

Experiences of the caregivers whose spouses were receiving chemotherapy for colorectal cancer and their expectations from nursing services were found to comprise the following themes "Facing the Disease," "Difficulties Encountered," "Continuing to Live," and "Provision of Health Care Services."

CONCLUSIONS

The results of the study revealed that cancer and its treatment affected not only cancer patients but also their spouses offering care. Nurses giving care at oncology clinics, public health centers, and home can make care plans based on the four themes emerging in this study and can detect problems earlier and create appropriate solutions to them. They will contribute to the literature revealing needs of people offering care to oncology patients as well.

Importance of Glycemic Control in Cancer Patients with Diabetes: Treatment through End of Life

Cancer patients with diabetes are at increased risk for developing infections, being hospitalized, and requiring chemotherapy reductions or stoppages. While it has been hypothesized that glycemic control increases the risk for these adverse events, few studies have explored this hypothesis. The purpose of this paper is to discuss the importance of glycemic control in patients with diabetes and cancer during treatment through end of life. Glycemic control was found to play a role; the overall level of health-related quality of life experienced by patients with cancer and diabetes, level of symptom severity experienced and can impact the overall survival of the individual. Evidence-based policies and practice guidelines also need to be developed to help clinicians manage these patients during all phases of care. Using diabetes educators and advance practice, nurses to provide management and care coordination services need to be considered. Survivorship care plans should address both cancer and diabetes management. Finally, glycemic control should continue through end of life, with the main goal of avoiding hypoglycemic events.

Quality of Life and Its Determinants in Adult Cancer Patients Undergoing Chemotherapy Treatment in Pakistan

Objective:

Cancer is a leading cause of death worldwide. Likewise, in Pakistan, it is a major health problem, with an approximate increase each year. Cancer treatment, particularly chemotherapy, produces a detrimental effect on individuals’ well-being. Since the past few years, quality of life (QOL) is considered as the primary goal of cancer treatment in patients’ survival. This study aimed to assess the QOL and its determinants in adult cancer patients undergoing chemotherapy treatment.

Methods:

An analytical cross-sectional design was employed to achieve the study objectives, utilizing consecutive sampling technique. A total of 150 adult (>19 years) cancer patients were recruited from a Tertiary Care Hospital in Karachi, Pakistan. The data were collected using the Functional Assessment of Cancer Therapy-General, a QOL questionnaire. Multiple linear regression was run to determine the effect of predictor variables, with a mean QOL score.

Results:

The overall mean score of QOL as 57.37. The domains of physical and emotional well-being were mainly affected by the chemotherapy treatment. Variables such as no previous hospitalization and no significant changes in life events were positively associated with the QOL. On the other hand, being female, unemployed, chemotherapy side effects (>1 week), impaired socialization, and discrimination by family/relatives were negatively associated with the QOL.

Conclusions:

The study findings suggested an overall low QOL among adult cancer patients undergoing chemotherapy treatment. It is recognized as a stressful treatment, which adversely affects the QOL of cancer patients. Interventions should focus on both the physical and psychological issues and need to be addressed to improve the QOL of adult cancer patients.

An assessment of reliability and validity of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 among breast cancer patients in Qatar

Introduction

Breast cancer has been the most common cancer type that affects women worldwide and subsequent treatment is often associated with considerable psychological and quality of life (QoL).

Aim

This study aimed to assess psychometric properties of the Arabic version of the European Organization for Research and Treatment of Cancer (EORTC) general QoL questionnaire (QLQ-C30) for breast cancer patients in Qatar.

Materials and Methods

This is a cross-sectional hospital-based study conducted on 678 breast cancer patients using Arabic version of the EORTC QLQ-C30 tool.

Results

The mean age of women was 47.7 ± 10.2 years and 33.4% of women had consanguineous parents. Six subscales out of the nine met the standards of reliability with coefficients ranging from 0.55 to 0.89. The mean score of all functioning scales was high >55. Advanced breast cancer stages of III-IV had higher symptomatic scores significantly than those in early stages for the physical function, cognitive, fatigue, insomnia, appetite loss, constipation, and financial difficulties. Correlation coefficients between each item ranged from -0.113 to 0.960, and item 21 (tense) and item 23 (irritable) had strongest negative correlations with their corresponding emotional functioning subscale, whereas items 29 (physical condition) and 30 (overall QoL) had the strongest positive correlation with Global Health/QoL subscale. Item 6 (limited work) showed a higher correlation with fatigue (r = 0.749). Likewise, item 19 (pain interfered with daily activities) of the pain subscale had higher correlations with physical functioning, role functioning, and fatigue subscales.

Conclusion

Qatari Arabic version of the EORTC QLQ-C30 showed acceptable psychometric properties, which is a reliable and valid instrument, that can be used by oncologists.

Understanding the Challenges of Providing Holistic Oncology Nursing Care in Nigeria

This article describes the current state of cancer nursing and the various challenges that hinder the provision of effective nursing care to cancer patients in Nigeria. The major issue identified was the lack of specialized oncology nursing education which should actually form a basis for nurses to practice in the oncology setting. Other issues include poor facilities for oncology nursing care, lack of specific cancer centers resulting in the management of cancer patients in non-specialist wards. It is therefore recommended that solidified structure be put in place in order to establish and strengthen the nursing curriculum which has a strong potential for improving the knowledge and skills of nurses to care for people living with cancer in Nigeria.

Spiritual Needs and Quality of Life of Patients with Cancer

Background and Aim

Information about spiritual needs and quality of life (QoL) is limited in Iranian cancer patients. This study was conducted to determine the relationship between spiritual needs and QoL among cancer patients in Iran.

Methods

This correlational study included a convenience sample of 150 eligible cancer patients who were hospitalized in the oncology wards and outpatient clinics. Using two questionnaires; the spiritual needs survey and the European Organization for Research and Treatment of Cancer QoL Questionnaire-C30 data were collected. The data were analyzed by SPSS software version 19.

Results

Our findings showed that the total mean score of spiritual needs was (64.32 ± 22.22). Among the categories, the lowest score belonged to "morality and ethics" component (2.18 ± 1.64), and the highest score belonged to "positivity/gratitude/hope/peace" component (15.95 ± 5.47). The mean score of QoL was (79.28 ± 19.20). Among the categories, the lowest score belonged to "global health status" component (8.44 ± 3.64), and the highest score belonged to "functional" component (36.57 ± 10.28). Pearson correlation coefficient showed that spiritual needs score positively correlated with QoL (r = 0.22; P = 0.006).

Conclusion

The results of the present study suggest that information about the relationship between spiritual needs and QoL in patients with cancer. It should be improve QoL to meet spiritual need of these patients. In addition, the continuous and in-service education of cancer patients and nurses who work with them can be helpful in this area.

Complementary Therapy for Cancer Survivors: Integrative Nursing Care

Objective:

The number of cancer patients who survive more than 5 years after the completion of their initial treatment is increasing. Oncology nurses must consider the needs of long-term cancer survivors in addition to those of cancer patients undergoing treatment because cancer survivors experience anxiety over several issues, including the risk of recurrence and progression of cancer status and symptom management.

Methods:

We tried to examine the effect of complementary therapy (CT) to reduce anxiety. The experimental study compared an intervention group (5 males and 68 females) that underwent four CTs and a control group (5 males and 56 females) that received no intervention. The intervention group practiced the CTs in their home for 20 min/day, 2 days/week, for 8 weeks, for a total of 16 times, whereas the control group performed their usual routines. Stress response scale-18 (SRS-18) scores consisting of three subscales (depression-anxiety, temper-anger, and lethargy) were compared between the groups and across time within each group.

Results:

The intervention group reduced depression and anxiety significantly than the control group. Furthermore, the intervention group expressed the following positive feedback: “being able to relax,” “being distracted from their worries and anxieties,” “being able to sleep,” “feeling more in-touch with reality,” and “wanting to continue the practice.”

Conclusions:

The study might accurately reflect the perspectives of women with cancer because the majority of the patients were women. Meanwhile, the result suggests that CTs might be useful for long-term cancer survivors who experience anxiety that influence their quality of life.

Cost-Utility of Stepped Care Targeting Psychological Distress in Patients With Head and Neck or Lung Cancer

Purpose A stepped care (SC) program in which an effective yet least resource-intensive treatment is delivered to patients first and followed, when necessary, by more resource-intensive treatments was found to be effective in improving distress levels of patients with head and neck cancer or lung cancer. Information on the value of this program for its cost is now called for. Therefore, this study aimed to assess the cost-utility of the SC program compared with care-as-usual (CAU) in patients with head and neck cancer or lung cancer who have psychological distress. Patients and Methods In total, 156 patients were randomly assigned to SC or CAU. Intervention costs, direct medical costs, direct nonmedical costs, productivity losses, and health-related quality-of-life data during the intervention or control period and 12 months of follow-up were calculated by using Trimbos and Institute of Medical Technology Assessment Cost Questionnaire for Psychiatry, Productivity and Disease Questionnaire, and EuroQol-5 Dimension measures and data from the hospital information system. The SC program's value for the cost was investigated by comparing mean cumulative costs and quality-adjusted life years (QALYs). Results After imputation of missing data, mean cumulative costs were -€3,950 (95% CI, -€8,158 to -€190) lower, and mean number of QALYs was 0.116 (95% CI, 0.005 to 0.227) higher in the intervention group compared with the control group. The intervention group had a probability of 96% that cumulative QALYs were higher and cumulative costs were lower than in the control group. Four additional analyses were conducted to assess the robustness of this finding, and they found that the intervention group had a probability of 84% to 98% that cumulative QALYs were higher and a probability of 91% to 99% that costs were lower than in the control group. Conclusion SC is highly likely to be cost-effective; the number of QALYs was higher and cumulative costs were lower for SC compared with CAU.

Factors Associated with HPV Vaccination among Cambodian American Teenagers

OBJECTIVES

Parents have general influence over their children's health and health behavior. However, given the dearth of specific literature regarding knowledge level and social and cultural factors influencing HPV vaccination behaviors among Cambodian American (CA) parent, it is difficult to develop an effective, evidence-based public health HPV vaccination program. Therefore, the objectives of this study were to determine the HPV vaccine uptakes among CA teenagers and to examine factors influencing HPV vaccine uptakes.

DESIGN AND SAMPLE

A descriptive, cross-sectional survey design and a combination of network and targeted sampling methods were used.

RESULTS

CA mothers (n = 130) completed a health survey through face-to-face interviews in either English or Khmer language. Girls vaccination rates were 29% while that of boys was 16%. Awareness and knowledge of HPV among CA mothers was very low, and many believed that their daughters, who speak English and were educated in the U.S., had more knowledge about health than they did. Logistic regression analysis showed that CA girls had significantly higher odds of vaccination when their mothers possessed a higher level of English reading ability and had greater awareness and knowledge of HPV.

CONCLUSIONS

The strikingly low rates of HPV vaccination among CA girls and boys underscore the need to improve vaccination outreach, education, and uptake. The findings can be used to develop targeted public health HPV vaccination programs for CAs, which will reduce cervical cancer disparities.

The use of scalp cooling for chemotherapy-induced hair loss

Chemotherapy-induced hair loss is a common and distressing side effect of cancer therapy and is one of the major unmet challenges in cancer management. Scalp cooling can prevent chemotherapy-induced hair loss in some cancer patients with solid tumours receiving certain chemotherapy regimens. Recent evidence indicates that this technique does not increase the risk of scalp metastasis. A reduction in post-chemotherapy infusion duration of scalp cooling and the advancement in cool cap technology may assist clinicians in promoting scalp cooling to cancer patients. This article discusses recent research, scalp cooling guidelines, products available and implications for nurses and their organisations in providing scalp cooling. It also considers recent advancements in identifying genes associated with chemotherapy-induced hair loss and international research collaborations including a registry and a 'chemotherapy-induced hair loss action group'--all striving to improve the patient experience of chemotherapy-induced hair loss.

Correlating Emotional Intelligence and Job Performance Among Jordanian Hospitals' Registered Nurses

PROBLEM

Emotional intelligence (EI) is an ability to recognize our and others' emotions, and manage emotions in ourselves and in relationships with other people. A large body of research evidence outside nursing shows that measured (EI) abilities correlated with employee performance, motivation, and job satisfaction; and preliminary nursing research evidence shows the correlation between EI ability and nurses' clinical performance. There is less research on the EI ability of Jordanian nurses, and the present study was undertaken to address this gap.

METHODS

A descriptive, cross-sectional, correlation comparative design (nonexperimental) was employed. Six Jordanian hospitals were included in the study. Two hundred fifty questionnaires were distributed to prospective participants. One hundred ninety-four questionnaires were returned, giving a response rate of 78%. EI was measured using the Genos Instrument. Clinical performance was measured using a self-report measure.

FINDINGS

Findings demonstrated significant positive relationships between all subscales of EI and job performance, ranging from r = .250, p = .000 to r = .193, p = .007. Regression analysis indicated working in medical-surgical wards, recognizing and expressing emotions scores (β = 0.186, p = .048), and controlling emotions (β = 0.255, p = .027) explained 19.1% of variance in nurses' job performance.

CONCLUSIONS

The study findings confirm the correlation between nurse EI ability and clinical performance.

Update knowledge on cervical cancer incidence and prevalence in Asia

Cervical cancer is the second most common cause of cancer-related death among women worldwide, with over 500,000 new cases diagnosed annually and 50% mortality rate in Asia. In the United States, approximately 10,370 new cases of cervical cancer are diagnosed annually, and estimated 3,710 deaths occur from the disease, making it the sixth most common cause of malignancy among American women. This study aims to provide awareness about cervical cancer as well as an updated knowledge about the prevalence and incidence of cervical cancer in Asia.

Development of Booklet on Male Sexual Dysfunction, its Measures and Assessing its Impact on Knowledge of Patients with Urological Cancers

Objective:

Urological cancer and its surgeries have great impact on male sexuality which could have physical or emotional consequences. In India, speaking openly about the sexual matter is a taboo and an aspect considered forbidden. Therefore, the aim of the present study is to develop an information booklet about male sexual dysfunction and assess its impact on knowledge of patients with urological cancers.

Methods:

Information booklet was developed after literature review, and its content validity was established. Reliability of the questionnaire was 0.95. A randomized control trail using pre- and post-test design was used for 30 male urological cancer patients and was assigned to experimental group (15) who received information booklet and control group (15) who received standard treatment. Subjects in the experimental group were provided with opinionnaire during posttest. Data were analyzed using descriptive and inferential statistics.

Results:

In experimental group, 40% of the subjects were ≤ 40 years, whereas 27% in the control group (P = 0.699). The pre- and post-mean difference score was significantly higher in experimental group (mean difference - 5) than control group (mean difference - 0.4). All subjects (100%) opined that the information booklet was useful, adequate, self-explanatory, sequential, and clear.

Conclusions:

Information in the booklet will help subjects to understand the common sexual problems after urological surgeries and help them to cope with the problems, thereby improving their quality of life.

The Effect of Complementary Therapy for Hospital Nurses with High Stress

Objective:

This study was to examine the effect of complementary therapy (CT) for nurses with high stress levels. It was taken before we employ this technique for cancer survivors because cancer patients are a heterogeneous group that requires substantial resources to investigate.

Methods:

A quasi-experimental design with five groups was employed for this study. The groups were examined whether there were effects for reducing the stress and the differences in effectiveness among four intervention groups and a nonintervention group. Stress relief was measured using pulse rate and blood pressure measurements and the short form of the profile of mood states (POMS-SF). The participants practiced the therapy for 20 min twice per week for 3 weeks. A two-way factorial analysis of variance was used to analyze the data.

Results:

The study enrolled 98 nurses (92 female and 6 male) with a mean age of 37.3 ± 10.5 years (range: 22–60 years). Fifty-nine nurses had 10 or more years of nursing experience. There were significant differences in pulse rate and the POMS-SF scores. All groups were effective for reducing the stress level of high-stress nurses, whereas four intervention CT groups were not more effective than nonintervention group.

Conclusions:

The complementary therapies were useful for nurses with high stress levels. Thus, they can be used as a self-management tool for such nurses. Afterward, we will use the CT for cancer survivors to determine whether it can improve the quality of life of cancer patients.

Needs and Preferences of Partners of Cancer Patients Regarding a Web-Based Psychological Intervention: A Qualitative Study

BACKGROUND

Evidence-based, easily accessible, supportive interventions for partners of cancer patients are limited, despite the fact that they often suffer from diminished emotional, social, physical, and relational functioning. To develop a new intervention that will fit their demands, it is important to consult potential users.

OBJECTIVE

To examine partners' interest in a Web-based psychological intervention and to identify their needs and wishes regarding such an intervention.

METHODS

Semistructured interviews were conducted with 16 partners of cancer patients, who varied in terms of age, gender, education, employment, type, and stage of disease. Partners were asked (1) whether they would use a psychological Web-based intervention and which preconditions (maximum time, structure, participate alone or with their partner) it should meet; (2) which functionalities (information, peer support, online psychological counseling) the intervention should contain; and (3) which topics (eg, taking care of oneself) should be addressed. Data were coded by 2 coders independently.

RESULTS

The need for a Web-based intervention varied. Arguments for being interested in a Web-based intervention included the need for acknowledgement; the need for someone they could talk to; and the need for information, tips, and support. Based on their experiences as a partner of a cancer patient, participants would prefer an intervention that is not too time-consuming (about 1-2 hours a week) and which is based on a "step-by-step" approach, meaning that the content of the intervention should match the stage of their partner's disease. Also, they would prefer a positive approach, which means that the intervention should be a source of hope and energy. Most participants stated that they would prefer to participate without their ill spouse, because they do not want to burden their partners with their own problems. An intervention should contain information and optional peer support. Participants' opinions about online psychological counseling in the intervention were divided. Arguments for online psychological counseling were that a professional could check on them and they were able to ask questions. Arguments against online counseling were that partners were not in need for guidance or they had enough support from usual care. Topics with the highest priority were "coping with feelings and emotions," "should I or shouldn't I spare my partner?," "communicating with each other," "asking for help and refusing help," and "moving on with life after cancer treatment." Furthermore, participants suggested additional topics of "dare to enjoy" and "acceptance of the patient's disease."

CONCLUSIONS

A Web-based intervention can be a valuable addition to existing support initiatives for partners of cancer patients. This study provides important information about the content and form of such an intervention. Flexibility and a positive approach seem to be the most important features.

Quality of Life in CAM and Non-CAM Users among Breast Cancer Patients during Chemotherapy in Malaysia

Background

Complementary and alternative medicine (CAM) use has become increasingly popular among patients with cancer. The purposes of this study were to compare the QOL in CAM users and non-CAM users and to determine whether CAM use influences QOL among breast cancer patients during chemotherapy.

Methodology

A cross-sectional survey was conducted at two outpatient chemotherapy centers. A total of 546 patients completed the questionnaires on CAM use. QOL was evaluated based on the European Organization for Research and Treatment of Cancer (EORTC) core quality of life (QLQ-C30) and breast cancer-specific quality of life (QLQ-BR23) questionnaires.

Results

A total of 70.7% of patients were identified as CAM users. There was no significant difference in global health status scores and in all five subscales of the QLQ C30 functional scales between CAM users and non-CAM users. On the QLQ-C30 symptom scales, CAM users (44.96±3.89) had significantly (p = 0.01) higher mean scores for financial difficulties than non-CAM users (36.29±4.81). On the QLQ-BR23 functional scales, CAM users reported significantly higher mean scores for sexual enjoyment (6.01±12.84 vs. 4.64±12.76, p = 0.04) than non-CAM users. On the QLQ-BR23 symptom scales, CAM users reported higher systemic therapy side effects (41.34±2.01 vs. 37.22±2.48, p = 0.04) and breast symptoms (15.76±2.13 vs. 11.08±2.62, p = 0.02) than non-CAM users. Multivariate logistic regression analysis indicated that the use of CAM modality was not significantly associated with higher global health status scores (p = 0.71).

Conclusion

While the findings indicated that there was no significant difference between users and non-users of CAM in terms of QOL, CAM may be used by health professionals as a surrogate to monitor patients with higher systemic therapy side effects and breast symptoms. Furthermore, given that CAM users reported higher financial burdens (which may have contributed to increased distress), patients should be encouraged to discuss the potential benefits and/or disadvantages of using CAM with their healthcare providers.

Low expression of KLF17 is associated with tumor invasion in esophageal carcinoma

PURPOSE

KLF17 belongs to the Sp/KLF zinc-finger protein family as a regulator in tumor development. However, its expression and biologic function has remained unclear in EC.

METHODS

The esophageal carcinoma tissue samples and adjacent normal tissues were obtained from the Second Hospital of Hebei Medical University. Immunohistochemistry, Western blot, and transfection were applied to evaluate the expression and clinical significance of KLF17 in esophageal cancer.

RESULTS

In this study, we showed that KLF17 was overexpressed in esophageal normal samples compared to the cancer. Moreover, KLF17 was upregulated at lymph node non-metastatic cancer tissues when compared to metastatic cancer tissues. KLF17 overexpression decreased EC cell proliferation, migration and invasion ability. In contrast, the knockdown of KLF17 increased EC cell proliferation, migration and invasion ability.

CONCLUSION

These results suggest that KLF17 inhibits tumor development and may serve as a potential therapeutic target.

MiR-133a suppresses the migration and invasion of esophageal cancer cells by targeting the EMT regulator SOX4

MicroRNAs (miRNAs) are small, non-coding RNAs which can function as oncogenes or tumor suppressor genes in human cancers. In the present study, we demonstrated that the expression ofmiR-133a was dramatically decreased in examined esophageal squamous cell carcinoma (ESCC) cell lines and clinical ESCC tissue samples. Additionally, miR-133a expression was inversely correlated with tumor progression in ESCCs. We have found that over-expression of miR-133a significantly suppressed the proliferation, migration and invasion of ESCC cells in vitro. miR-133a over-expression also significantly suppressed the aggressive phenotype of ESCC in vivo, suggesting that miR-133a may function as a novel tumor suppressor. Further studies indicated that the EMT-related transcription factor Sox4 was a direct target gene of miR-133a, evidenced by the direct binding of miR-133a with the 3'UTR of Sox4. Notably, the EMT marker E-cadherin or vimentin, a downstream of Sox4, was also down-regulated or upregulated upon miR-133a treatment. We have also shown that over-expressing or silencing Sox4 was able to elevate or inhibit the migration and invasion of ESCC cells, similar to the effect of miR-133a on the ESCC cells. Moreover, knockdown of Sox4 reversed the enhanced migration and invasion mediated by anti-miR-133a. These results demonstrate that miR-133a acts as a tumor suppressor in ESCC through targeting Sox4 and the EMT process. miR-133a may serve as a potential target in the treatment of human esophageal cancer.

Risk of cancer with combined oral contraceptive use among Iranian women

Oral contraceptive use is the most common type of contraception. More than 300 million women worldwide take oral contraceptives every day. However, there is a concern about the relationship with the incidence of cancer. This analytical retrospective study aimed to investigate the relationship between the incidence of cervical and breast cancers and oral contraceptive use in 128 Iranian patients with cervical cancer, 235 with breast cancer and equal numbers of controls. Data were collected through interviews with an organized set of questions. Details were also extracted from patient files. Data were analyzed using Student's t-test, chi-square and Fisher's exact tests, and Pearson's correlation analysis. The result revealed correlations between both cervical and breast cancers and history of contraceptive pills use. While cervical cancer significantly correlated with duration of use of pills, breast cancer had significant correlations with the type of oral contraceptive and age at first use. No significant relationships were found between the two types of cancer and age at discontinuation of oral contraceptives, patterns of use, and intervals from the last use. The use of oral contraceptives may triple the incidence of cervical cancer and doubles the incidence of breast cancer. Therefore, performing Pap smears every six months and breast cancer screening are warranted for long-term oral contraceptive users.

Minichromosome maintenance complex component 7 has an important role in the invasion of papillary urothelial neoplasia

The aims of the present study were to investigate the expression of minichromosome maintenance complex component 7 (MCM7) and determine its association with tumor proliferation and invasion in pathological tumor (pT)a and pT1 papillary urothelial neoplasia. The MCM7, MCM3 and Ki67 proteins were detected in 154 cases of urothelial neoplasia using immunohistochemical analysis. The expression of MCM7 significantly increased (P<0.001) as the pathological stage and grade progressed between inverted papilloma, papillary urothelial neoplasm of low malignant potential (PUNLMP), pTa tumor and pT1 tumor. However, no statistically significant difference in MCM7 staining was observed between low-grade pTa tumors and PUNLMP (P=0.2294). In contrast to MCM7, MCM3 was highly expressed in all stages of urothelial neoplasia, with no statistically significant differences observed between the tumor types (P=0.2993, 0.3885 and 0.8489 for pTa tumors, PUNLMP and inverted papiloma, respectively). Furthermore, MCM7 expression was elevated with increased tumor grade and was positively correlated with Ki67 expression (r_s =0.9106, P<0.001). However, MCM3 expression was not correlated with MCM7 or Ki67 expression (r_s =0.0734, P=0.3657 and r_s =0.0638, P=0.4318, respectively). In conclusion, MCM7 overexpression may simultaneously promote tumor proliferation and invasion. Furthermore, it may be a reliable marker for the pathological differential diagnosis of pTa and pT1 papillary urothelial neoplasms; therefore, MCM7 expression may be used to predict tumor prognosis and behavior.

Protein-DNA array-based identification of transcription factor activities differentially regulated in obliterative bronchiolitis

Lung transplantation has already become the preferred treatment option for a variety of end-stage pulmonary failure. However the long-term results of lung transplantation are still not compelling and the major death reason is commonly due to obliterative bronchiolitis (OB) which is considered as chronic rejection presenting manifests physiologically as a progressive decline in FEV1. Transcription factors (TFs) play a key role in regulating gene expression and in providing an interconnecting regulatory between related pathway elements. Although the transcription factors are required for expression of the proinflammatory cytokines and immune proteins which are involved in obliterative bronchiolitis following lung transplantation, the alterations of the transcription factors in OB have not yet been revealed. Therefore, to investigate the alteration pattern of the transcription factors in OB, we used protein/DNA arrays. Mice orthotopic tracheal transplantation model was used in this studying. In this study, we explored the activity profiles of TFs in Protein/DNA array data of tracheal tissue in 14 and 28 day after transplanted. From a total of 345 screened TFs, we identified 42 TFs that showed associated with OB progression. Our data indicate that TFs may be potentially involved in the pathogenesis of OB, and can prevent, diagnose and treat OB after lung transplantation. In development of OB, some of the TFs may have ability to modulate the transcription of inflammatory proteins such cytokines, inflammatory enzymes and so on.

Renal access through the inferior calyx is associated with higher risk of severe bleeding after percutaneous nephrolithotomy

INTRODUCTION

Hemorrhage is a major complication after percutaneous nephrolithotomy (PCNL). In the current study, we analyzed the risk factors for severe bleeding after PCNL.

MATERIAL AND METHODS

Medical records of 982 consecutive patients undergoing PCNL at the Department of Urology, the Third Xiangya Hospital, were reviewed. The type of stone included: solitary (n = 471), multiple (n = 192) and staghorn (n = 319). 139 patients had renal stones of solitary kidney or functional solitary kidney. The puncture site was the inferior calyx in 246 cases, the middle calyx in 651 cases, and the upper calyx in the remaining 85 cases.

RESULTS

The success rate (complete removal of the stone) was 92.8%, 73.4%, and 80.9% for solitary, multiple and staghorn stones, respectively. Severe bleeding occurred in 3.25% (8/246) of the cases with inferior calyx access, and 0.3% (2/651) in cases with middle calyx access. No severe bleeding occurred in patients with upper calyx access. The bleeding was controlled successfully with focal embolization under angiography in all 10 cases.

CONCLUSIONS

Severe postoperative bleeding after PCNL is associated with renal puncture via the inferior calyx, multiple renal stones and solitary kidney stones.

A web-based self-help intervention for partners of cancer patients based on Acceptance and Commitment Therapy: a protocol of a randomized controlled trial

BACKGROUND

There is a growing recognition that cancer not only affects the lives of the patients, but also the lives of their partners. Partners of cancer patients are highly involved in the illness trajectory by providing informal care and they often experience distress. However, supporting interventions for this group are scarce and existing interventions bear several limitations. On the basis of the need for theory- and evidence-based supportive interventions for partners of cancer patients, the web-based self-help intervention Hold on, for each other has been developed. This intervention is based on Acceptance and Commitment Therapy. The primary objective of the RCT is to investigate the (cost-) effectiveness of the intervention. Additional goals are (1) to examine if psychological flexibility, self-compassion, mastery, supportive behavior, posttraumatic growth and resilience are mediators of the intervention's effects on the partners' mental health; (2) to examine the moderating effects of the socio demographics (age, gender, education, working situation, family situation) and disease-related characteristics of the patients (sort of cancer, stage of disease, duration and treatment of cancer); and (3) to investigate to what extend participants are satisfied with the intervention, which parts of the intervention are mostly used, and how adherent the users are.

METHODS/DESIGN

A three-armed randomized controlled trial (RCT) will be conducted to compare two versions of the intervention Hold on, for each other with a waiting list control condition. Both intervention conditions contain the same content and differ only with regard to the form of professional support (personal support versus automatic support). Adult partners of cancer patients with mild to moderate depressive and anxiety symptoms, will be recruited through a multi-component strategy. Online measurements by self-assessment will be made on four measurement points (prior to randomization (baseline-measurement) and 3, 6 and 12 months after baseline).

Measurement of chemotherapy-induced alopecia-time to change

Data on chemotherapy-induced alopecia (CIA) as a side effect of cancer treatment are scarce. CIA is given minimal attention in clinical trials and in the literature. However, when asking the patients with cancer for their opinion, CIA appears to have a major impact, particularly on body image and quality of life. Currently, there is no commonly used measure to evaluate CIA; It is time to improve the management and measurement of CIA.

Effects of micronutrients on the reproduction of infertility rat model induced by adenine

Male infertility is a serious global medical and social issue demanding more specific and effective treatments. In this study, we generated a male infertility rat model using adenine induction to study the effects of certain micronutrients on reproduction. Fifty male SD rats were used in the study, and thirty of them received daily intra-gastric administration of 300 mg/kg adenine for four weeks. The thirty adenine treated mice were evenly divided into 3 groups to receive intra-gastric administration of micronutrient mixture of vitamin A, vitamin C, vitamin E, Zinc, and selenium (micronutrient group), normal saline (model control group), and methyl testosterone solution (androgen group). The other twenty rats used were normal male SD rats that were evenly divided into two groups to receive intra-gastric administration of normal saline (normal control group) and micronutrient mixture first then adenine 40 min later (micronutrient prevention group). After four weeks of micronutrient and other treatments, all rats were sacrificed for analyses. Compared with those in the model control group, the rats in the micronutrient group showed significantly improved physical signs, significantly increased body weights, significantly increased testis index, significantly increased sperm counts and motility, significantly decreased sperm malformation, and significantly repaired testis tissue. Compared with those in the model control group, the rats in the micronutrient group showed significantly decreased FSH levels and recovered LH and testosterone levels. The rats in the micronutrient prevention group did not show significant differences in sperm counts, sperm motility, sperm malformation, and hormonal levels from those in the normal control group. The findings from this study provide evidence for the potential application of micronutrients in male infertility treatments.

Mechanisms for steep pulse irreversible electroporation technology to kill human large cell lung cancer cells L9981

To explore the mechanisms for steep pulse irreversible electroporation technology to kill the lung cancer cell L9981. The apoptosis, cells mitochondrial membrane potential, internal PH changes and the intra-cellular calcium ions concentration were detected after steep pulses acted on the human large cell lung cancer cell L9981. Apoptosis test results indicated that cancer cells mainly experienced necrosis and apoptosis. Along with the increase of electric parameters, the proportion of the necrotic cells increased rapidly; the detection of cells mitochondrial membrane potential indicated that membrane potential occurred depolarization. Steep pulse can cause cancer cells to produce death and apoptosis .The PH value indicated that intracellular PH level down jumped. Internal PH became more acidic and led to cell death. The detection of intra-cellular calcium ions concentration showed that the number of free calcium significantly increased, and this change had killing effects on cell death and apoptosis. Steep pulse could induce cell apoptosis.

CEACAM5 has different expression patterns in gastric non-neoplastic and neoplastic lesions and cytoplasmic staining is a marker for evaluation of tumor progression in gastric adenocarcinoma

OBJECTIVE

The aim of this study was to investigate the expression patterns of CEACAM5 in non-neoplastic and neoplastic gastric lesions, as well as its application in the differential diagnosis and its relationship with tumor progression.

METHODS

CEACAM5 expression was detected by immunohistochemical staining in the serial sections of the gastric neoplastic and non-neoplastic lesions. The impacts of CEACAM5 expression patterns on tumor progression were evaluated by statistics, the clinical and pathological data included sex, age, tumor extension, lymph node involvement and tumor staging.

RESULTS

There was no CEACAM5 expression in normal gastric epithelial cells. In hyperplastic polyps, CEACAM5 was expressed with apical membranous staining in the hyperplastic and prolonged gastric pit adjacent to the surface. Intestinal metaplasia (IM) expressed CEACAM5 mainly with membranous pattern, and some cases showed membranous staining mixed with cytoplasmic staining. GIN expressed CEACAM5 mainly with membranous staining, but the mixed staining of cytoplasmic and membranous patterns increased, and especially in the high grade GIN, cytoplasmic staining of CEACAM5 began to occur. Compared with IM and GIN, CEACAM5 expression patterns of hyperplastic polyp showed a significant difference (P=0.000). IM, low grade GIN and the whole GIN showed no significant difference in CEACAM5 expression patterns (P=0.355), but IM and high grade GIN showed a significant difference (P=0.027). There was a significant difference between low and high grade GIN (P=0.002). GIN and well-differentiated carcinomas showed no significant difference (P=0.070), but low grade GIN and well differentiated carcinomas showed a significant difference (P=0.006). In gastric adenocarcinomas, CEACAM5 expression patterns showed a significant difference in tumor grading (P=0.010) and Laurén classification (P=0.001). In histological grading, well differentiated carcinomas showed more membranous staining than moderately and poorly differentiated, and more cytoplasmic CEACAM5 staining was detected in moderately and poorly differentiated carcinomas. Similar to that, in Laurén classification, intestinal carcinomas showed more membranous staining, and diffuse carcinomas showed more cytoplasmic staining. Moreover, CEACAM5 expression patterns showed a significant difference in tumor extension (P=0.012), lymph node involvement (P=0.015) and tumor staging (P=0.002), suggesting that CEACAM5 should be involved in tumor progression. In advanced carcinomas, CEACAM5 was expressed with more cytoplasmic staining regardless of the histological classification.

CONCLUSION

CEACAM5 had different expression patterns in gastric non-neoplastic and neoplastic lesions. The CEACAM5 expression patterns were associated with tumor progression. Membranous staining of CEACAM5 might be a marker of premalignancy in gastric lesions, and cytoplasmic CEACAM5 might enhance tumor invasion and migration and be an evaluated marker for progressive and advanced gastric cancer. Also, it might be useful for the differential diagnosis of gastric premalignant lesions.
