RESUMO

BACKGROUND: Adressing mental distress among cancer patients presents a substantial challenge in the delivery of oncology care. AIMS: This present study aims to explore the nursing strategies for identifying and managing distress in cancer patients as well as the concomitant barriers that prevent them from achieving this task. METHODS: This qualitative study is based on a semi-structured interview with 25 practicing nurses in oncology. RESULTS: Strategies used by nurses to identify mental distress in their patients include: receiving information, mobilizing interpersonal skills, and identifying causes of distress. When asked about the barriers that hinder the practice of identifying and responding to patients' distress, nurses reported facing several barriers that can be classified into three categories: health care system-related barriers, patient-related barriers, and nurse-related barriers. CONCLUSION: Oncology nurses should benefit from specific training on the systematic assessment of mental distress in cancer patients, in order to improve the overall management of oncology patients.

RESUMO

Background: Breast cancer is the most common female cancer in the world. Sleep disruption is one of the major problems of breast cancer patients. This study aimed to evaluate the quality of sleep in a group of Moroccan women with breast cancer and analyze the association between sleep quality, depression, and anxiety. Methods: This cross-sectional study was carried out among 337 Moroccan women treated for breast cancer at the Mohammed VI Cancer Treatment Center in Casablanca in 2019. A questionnaire was designed for this purpose based on two scales: Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety Depression Scale (HADS). Results: 71.5% of the participants had significant sleep disturbances; the subjective quality of patients' sleep was considered to be quite poor (20.8%) and 43.9% of participants need more than 60 minutes to fall asleep. The average sleep duration was 6.16 h/night and 84.3% of patients had not taken sleep medicines in the last month. The most common reasons for sleep disturbances were getting up to use the bathroom (67.4%) and waking up in the middle of the night or early morning (54%). Anxiety and depression were positively correlated with PSQI scores. Conclusion: The present study highlights how much breast cancer patients are vulnerable to psychological disorders and then incites the decision makers in oncology departments to implement rigorous psychological health care strategies in order to ameliorate mental health and sleep quality of breast cancer patients.

RESUMO

Mental health disorders are common in cancer patients. However, these disorders are still underestimated in oncology. The aim of the present study is to examine the effect of breast cancer and gynecological cancer on mental health disorders in women who have undergone nonsurgical antineoplastic treatment for gyneco-mammary cancer and to investigate the predictors of these mental disorders. Material and Methods: A cross-sectional study was carried out on Moroccan women treated with nonsurgical treatment for breast or gynecological cancer (N=200). The Hospital Anxiety and Depression Scale, Body Image Scale, Pittsburgh Sleep Quality Index, Rosenberg's Self-Esteem Scale, and Multidimensional Scale of Perceived Social Support, were used. Results: The type of cancer had a significant effect on mental health disorders but not the age. Women with breast cancer had significantly more mental health problems than women with gynecological cancer (P-values ​​<0.01). The predictive model of anxiety included the effects of the following variables: having a lower school level and an advanced tumor stage. While the predictive model of depression included advanced tumor stage and disease recurrence. For poor sleep quality, the variables included were: not having an occupation and having a lower monthly income. The variables that predicted body image dissatisfaction were: being younger, being unmarried, and living in a rural area. Conclusion: High mental distress in women with breast cancer and gynecological cancer is favored by several predictive factors. The implementation of a protocol for the assessment and management of distress is necessary in oncology departments.

RESUMO

BACKGROUND: Sleep quality is among the indicators associated with the quality of life of patients with cancer. A multitude of factors may affect patient sleep quality and are considered as associated predictive factors. The aim of this study was to examine the predictors of poor sleep quality in Moroccan women with gynecological cancer after radical surgery. METHODS: A cross-sectional study was carried out at the Oncology Department of the Ibn Rochd University Hospital, Casablanca (Morocco), on women who had undergone radical surgery for gynecological cancer (n = 100; mean age: 50.94 years). To assess sleep quality, symptoms of depression and anxiety, self-esteem and body image, the following translated and validated Arabic versions of the tools were used: Pittsburgh Sleep Quality Index (PSQI), Hospital Anxiety and Depression Scale, Rosenberg's Self-Esteem Scale and Body Image Scale. To determine predictors of sleep quality, multiple linear and hierarchical regressions were used. RESULTS: 78% of participants were considered poor sleepers, most of them exhibited very poor subjective quality (53%), longer sleep onset latency (55%), short period of sleep (42%) and low rate of usual sleep efficiency (47%). 79% of these patients did not use sleep medication and 28% were in poor shape during the day. Waking up in the middle of the night or early in the morning and getting up to use the bathroom were the main reasons for poor sleep quality. Higher PSQI scores were positively correlated with higher scores of anxiety, depression, body image dissatisfaction and with lower self-esteem (p < 0.001). The medical coverage system, body image dissatisfaction and low self-esteem predicted poor sleep quality. After controlling for the socio-demographic variables (age and medical coverage system), higher body image dissatisfaction and lower self-esteem significantly predicted lower sleep quality. CONCLUSION: Body image dissatisfaction and lower self-esteem were positively linked to sleep disturbance in women with gynecological cancer after undergone radical surgery. These two predictors require systematic evaluation and adequate management to prevent sleep disorders and mental distress as well as improving the quality of life of these patients.

RESUMO

INTRODUCTION: In lower-middle-income countries, significant progress has been made in the therapeutic management of cancers. However, mental health disorders related to these diseases are usually underestimated by the health system. The aim of this study is to investigate the predictive factors for mental health disorders in Moroccan women with breast or gynecological cancer treated by radical surgery. MATERIAL AND METHODS: A cross-sectional study was carried out on Moroccan women treated by radical surgery for breast or gynecological cancer (N = 200). For each cancer type, patients were divided into two groups following age criteria. Hospital Anxiety and Depression Scale and Body image scale were used. RESULTS: Age had a significant effect on mental health disorders but not the type of cancer. Younger women showed significantly greater mental health disorders than older women (p ≤ 0.001). The predictive model for high anxiety and depression included the effect of the following variables: Being younger, having lower income, and advanced tumor stage. For higher body image dissatisfaction, the variables are as follows: being younger, having fewer children, lower-income, and advanced tumor stage. CONCLUSION: The association of mental health disorders in patients with breast or gynecological cancer increases their distress. The establishment of management protocols for these disorders is strongly recommended in oncology departments.

RESUMO

INTRODUCTION: Psychosocial determinants can affect the mental health of women who have been diagnosed with gynecological cancer. The aim of this study was to examine how social support and self-esteem are associated with anxiety and depression symptoms in women with gynecological cancer, and who are treated by radical surgery. METHODS: A cross-sectional study was performed, within the oncology department of Ibn Rochd University Hospital, Casablanca, on 100 Moroccan women. They all had undergone radical surgery for gynecological cancer, hysterectomy and/or oophorectomy. RESULTS: Our results showed that patients with gynecological cancer treated by radical surgery exhibited high prevalence rates of anxiety (66%) and depression symptoms (59%). Associations showed that age, having children, medical coverage system, area of residence, working status and socioeconomic status were significantly related to the prevalence of anxiety and depression symptoms (P<0.05). The general social support, family support and significant other support besides high self-esteem reduce significantly the risk of getting anxiety and depression symptoms (P-values<0.05). DISCUSSION: Among patients with gynecological cancer treated by radical surgery, high prevalence of anxiety and depression symptoms was found. Social support and high self-esteem could help improve mental health issues related to this type of cancer.

RESUMO

Background: Breast cancer is the leading cause of cancer death in women worldwide with more than 1. 7 million new cases annually. Major advances have been made in the therapeutic management of this condition in many countries. However, neuropsychiatric disorders in patients with breast cancer constitute a significant concern due to their negative impact on patient's life and on the success of therapy itself. Methodology: In this study we aimed to evaluate psychological disorders in a population of 212 Moroccan women treated for breast cancer within the Mohammed VI Center for the Treatment of Cancers of Casablanca. A questionnaire was designed to this end on the basis of different validated scales, including the Hospital Anxiety Depression Scale (HADS), the Pittsburgh Sleep Quality Index (PSQI), and the Body Image Scale (BIS). Results: Data analysis has shown that 69.3% of participants had significant sleep disorders; 87% suffer from an anxiety-depressive syndrome (ADS), and 83.0% had significant body image dissatisfaction. A positive correlation was shown between ADS and both patients' national health insurance coverage and patients or husbands' education. Analysis further revealed that anxiety and depression were negatively correlated with different types of treatment. Similarly, both BIS and PSQI scores were positively associated with anxiety and depression disorders. Conclusion: The present investigation highlights the need to generalize and strengthen the psychological approach of patients treated for breast cancer in Morocco. We anticipate that such a strategy will alleviate suffering and promote therapy success in these patients and will diminish or prevent conjugal and familial impacts of the illness.

RESUMO

HPV infection is associated with cervical cancer, one of the major public health problems in developing countries. In the Republic of Congo, despite of the high age-standardized incidence rate estimated at 25.2 per 100,000 women, molecular epidemiology data on HPV infections are very limited. We investigated HPV genotypes distribution in cervical smears among patients attending the General Hospital of Loandjili, Southwest Congo. A cross-sectional hospital-based study was conducted on 321 women. Liquid-based cytology samples were collected for cytological diagnosis and HPV detection. Nested-PCR was performed using MY09/MY11 and GP5+/GP6+ primers with genotyping by direct sequencing. Type-specific PCR for HPV-6, -11, -16, -18, -31 and -33 was also used to assess multiple infections. Out of 321 women examined, 189 (58.8%) had normal cytology, 16 (5.0%) had ASCUS and 116 (36.1%) had cytological abnormalities. HPV-DNA was detected in 22 (11.6%), 6 (37.5%), and 104 (89.6%) normal cytology, ASCUS and cytological abnormalities respectively. HPV16 was the most prevalent genotype regardless of cytological status followed by HPV70 in women without lesions and HPV33 among those with lesions. HR-HPV prevalence varied significantly according to the cervical cytology (P = 0.000). Among women without lesions, two peaks of HPV infections were observed in age group less than 30 years (60.0%) and in age group 50-59 years (7.1%). Age, age of first sex, multiple sexual partners and pregnancies were the risk factors for HPV infection in women without lesions. Our findings could be used as evidence data base for future epidemiological monitoring in this region.

RESUMO

BACKGROUND: Cervical cancer is the commonest cancer and the leading cause of cancer mortality in women in Gabon. The age-standardized incidence of cervical cancer is 19.9 per 100 000 women and the mortality rate is 8.4 per 100 000. Various international studies have identified the lack of awareness and knowledge about cervical cancer as barriers to use preventive methods. This article assesses the awareness and knowledge about cervical cancer, Pap smear testing and its use and HPV among women living in Libreville, Gabon. METHODS: This study was conducted in October 2014 in Libreville. A total of 452 women aged 16 years and above were recruited from different town locations. Logistic regression analysis was used to identify the effect of demographic characteristics on the level of knowledge about cervical cancer, Pap smear testing and HPV. Odds ratio and 95% confidence intervals were used to identify the strength of association. Associations were considered statistically significant at p < 0.05. RESULTS: Of all the women interviewed, 91.6% (414/452) had heard about cervical cancer and only 27.9% (126/452) had heard of Pap smear test. Of these 126 women, only 65.1% (82/126) had done cervical cancer screening and 68.3% (56/82) on the suggestion of a doctor. The most common reason for not undergoing Pap smear testing was neglect (50%, 22/44) followed by lack of financial resources (13.6%, 6/44), fear of discovering a serious disease (13.6%, 6/44) and deeming it unimportant (13.6%, 6/44). Only 8% (40/452) of the participants had heard about HPV and their knowledge of HPV was fair. There is a very poor level of knowledge about cervical cancer among Gabonese women. CONCLUSION: This study demonstrates a very low level of knowledge about cervical cancer, Pap smear testing and HPV in a sample of Gabonese women. There is a critical need for Gabonese women to be informed about cervical cancer and the Pap smear test to improve the use of this preventive method. The implication of health staff and Gabonese media should be included as a centerpiece in the effort to inform the population in order to reduce the burden of cervical cancer in Gabon and save women lives.

RESUMO

BACKGROUND: Knowledge on HPV prevalence and genotype distribution in HSIL and ICC is highly essential for the introduction of an effective vaccination program and appropriate epidemiological monitoring of viral ecology before and after vaccination in Congo. This study aimed to determine the specific-HPV genotypes in HSIL and ICC among women in southwestern Congo. METHODS: 125 archival paraffin-embedded biopsy collected between 2008 and 2012 and histologically diagnosed were investigated. DNA extraction was performed using the phenol/chloroform method. HPV search was performed by nested-PCR using MY09/MY11 and GP5+/GP6+ consensus primers followed by direct sequencing. RESULTS: The mean age of participants was 44.3 ± 8.2 years. Overall, HPV prevalence was 89.6% (112/125) with all high-risk genotypes. HPV-DNA was detected in 81.5% (53/65) of HSIL and 98.3% (59/60) of ICC. HPV 16 the most common genotype was detected in 47.1% (25/53) of HSIL and 52.5% (31/59) of ICC. Other types identified were: HPV 33 (22.6%), HPV 18 (15%), HPV 31 (11.3%) and HPV 69 (3.7%) in HSIL, and HPV 33 (28.8%), HPV 18 (11.8%), HPV 31 (5%) and HPV 35 (1.7%) in ICC. Knowing that the ADC accounted for 6.7% (4/60) of ICC cases, HPV 18 was identified in 25% (1/4) of these cases against 75% (3/4) for HPV 16. CONCLUSION: Our study showed that HPV 16, 33, 18 and 31 were the four most common genotypes in women with HSIL and ICC. These findings indicate that current vaccines against HPV could help to reduce the burden of cervical cancer in Congo.

RESUMO

Undifferentiated cell Transcription Factor 1 (UTF1) is a chromatin-bound protein involved in stem cell differentiation. It was initially reported to be restricted to stem cells or germinal tissues. However, recent work suggests that UTF1 is also expressed in somatic cells and that its expression may increase during carcinogenesis. To further clarify the expression profile of UTF1, we evaluated UTF1 expression levels immunohistochemically in eight normal human epithelia (from breast, prostate, endometrium, bladder, colon, oesophagus, lung and kidney) and their corresponding tumours as well as in several epithelial cell lines. We showed UTF1 staining in normal and tumour epithelial tissues, but with varying intensities according to the tissue location. In vitro analyses also revealed that UTF1 is expressed in somatic epithelial cell lines even in the absence of Oct4A and Sox2, its two main known regulators. The comparison of UTF1 levels in normal and tumoral tissues revealed significant overexpression in endometrial and prostatic adenocarcinomas, whereas lower intensity of the staining was observed in renal and colic tumours, suggesting a potential tissue-specific function of UTF1. Altogether, these results highlight a potential dual role for UTF1, acting either as an oncogene or as a tumour suppressor depending on the tissue. These findings also question its role as a specific marker for stem cells.

RESUMO

Cervical cancer is a major public health concern in Morocco where it represents the second most common and lethal cancer in women. Human papillomavirus (HPV) vaccines have been licensed in Morocco since 2008 but there are no available data on their acceptability. This study aimed to assess awareness of HPV and the vaccine, and to identify factors associated with acceptability of the vaccine among parents in Morocco. We carried out a questionnaire-based survey using face-to-face interviews in a sample of 852 parents (670 mothers and 182 fathers) with at least one unmarried daughter ≤26 years. We collected data within public and private health centres and clinics in four regions in Morocco between July and August 2012. The main outcome measure was parental acceptability of the HPV vaccine for their daughter(s). Responses revealed very low awareness of HPV infection (4.7%) and the HPV vaccine (14.3%). None of the participants had vaccinated their daughter(s) against HPV and vaccine acceptability was low among mothers (32%) and fathers (45%). Higher education and income, previous awareness of the HPV vaccine and endorsement of the belief that a recommendation from the Ministry of Health or a doctor to have the vaccine would be encouraging, were associated with mothers' HPV vaccine acceptability. Non-acceptability among mothers was associated with having more than two daughters, believing the vaccine was expensive, lack of information and believing that whatever happens to an individual's health is God's will. The only factor associated with the fathers' acceptability of the vaccine was the cost of the vaccine. Increasing HPV and HPV vaccine awareness through educational campaigns, along with active recommendation by physicians and a publically funded vaccination programme could increase parental acceptability of the HPV vaccine in Morocco.

RESUMO

Promoter methylation profiles are proposed as potential prognosis and/or diagnosis biomarkers in cervical cancer. Up to now, little is known about the promoter methylation profile and expression pattern of stem cell (SC) markers during tumor development. In this study, we were interested to identify SC genes methylation profiles during cervical carcinogenesis. A genome-wide promoter methylation screening revealed a strong hypermethylation of Undifferentiated cell Transcription Factor 1 (UTF1) promoter in cervical cancer in comparison with normal ectocervix. By direct bisulfite pyrosequencing of DNA isolated from liquid-based cytological samples, we showed that UTF1 promoter methylation increases with lesion severity, the highest level of methylation being found in carcinoma. This hypermethylation was associated with increased UTF1 mRNA and protein expression. By using quantitative RT-PCR and Western Blot, we showed that both UTF1 mRNA and protein are present in epithelial cancer cell lines, even in the absence of its two main described regulators Oct4A and Sox2. Moreover, by immunofluorescence, we confirmed the nuclear localisation of UTF1 in cell lines. Surprisingly, direct bisulfite pyrosequencing revealed that the inhibition of DNA methyltransferase by 5-aza-2'-deoxycytidine was associated with decreased UTF1 gene methylation and expression in two cervical cancer cell lines of the four tested. These findings strongly suggest that UTF1 promoter methylation profile might be a useful biomarker for cervical cancer diagnosis and raise the questions of its role during epithelial carcinogenesis and of the mechanisms regulating its expression.

RESUMO

OBJECTIVE: The aim of this study was to determine the prevalence of human papillomavirus (HPV) in 80 tumor-free tonsils from healthy children and adults using a sensitive E6/E7 type-specific polymerase chain reaction (PCR). STUDY DESIGN: Cross-sectional study. SETTING: Ear, nose, and throat department, university hospital. SUBJECTS AND METHODS: Paraffin-embedded tissues from tumor-free tonsils (TFTs) were evaluated for HPV DNA using GP5+/6+ consensus PCR and subsequent genotyping using E6/E7 type-specific PCR for HPV types 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, and 68. The immunohistochemical expression of p16 and p53 was also assessed. RESULTS: In 80 TFTs, the authors identified 10 (12.5%) that tested positive for the following high-risk HPV types: HPV 16 (8 cases), 18 (1 case), and 31 (1 case). Twelve patients (15%) tested positive for HPV infection using the GP5+/GP6+ consensus primers but were negative using quantitative PCR. These patients were considered infected with low-risk HPV types. Fifty-eight TFTs (72.5%) tested negative for both GP5+/GP6+ and type-specific HPV PCR analysis (HPV negative). Among patients infected with HPV, the authors observed a slight increase in frequency with age. CONCLUSION: In TFTs, oncogenic and nononcogenic HPVs were present at a relatively high frequency in children and adults. The presence of high-risk HPV DNA in young children supports the horizontal transmission hypothesis and argues in favor of HPV vaccination at birth.
