RESUMO
BACKGROUND: patients with locally advanced breast cancer (LABC) are often treated by neoadjuvant chemotherapy (NACT). This study aims to determine the prevalence of psychological distress and their sociodemographic and clinical factors in patients recently diagnosed with LABC and before NACT. METHODS: A total of 209 LABC patients without metastatic localization were recruited between 2021 and 2022 in the oncology hospital at Fez. A structured questionnaire and the Hospital Anxiety and Depression Scale were used. A descriptive analysis and linear model were performed. RESULTS: a mean age of participants was 47.43 ± 9.45 years. The prevalence of depression, anxiety and psychological distress among participants was 59.62% (95% CI: 52.61-33.34), 47.85% (95% CI: 40.91-54.85), and 65.07 (95% CI: 58.19-71.52) respectively. Depression was associated to age (< 50 years) (AOR = 2.19; 95% CI = 1.13-4.23) and health insurance (AOR = 3.64; 95% CI: 1.18-11.26). Anxiety was associated to age (< 50) (AOR = 2.21; 95% CI: 1.18-4.13) and right breast cancer (AOA = 2.01; 95% CI: 1.11-3.65). Psychological distress was associated to chronic illness (AOR = 2.78; 95% CI: 1.32-5.85) and lymph node status (AOR = 2.39; 95% CI: 1.26-4.57). CONCLUSIONS: Based on the high prevalence of depression and anxiety it appears opportune to treat psychological distress among LABC patient candidates for NACT. Each psychological intervention should take into account sociodemographic and clinical factors found associated in our study. Psychological therapeutic interventions are crucial for LABC patients as early as the time of diagnosis and through subsequent steps in NACT to improve their overall mental health.

BACKGROUND: Physical activity has been associated with a lower risk of colorectal cancer in studies mainly conducted in high-income countries, while sedentary behavior has been suggested to increase CRC risk. In this study, we aimed to investigate the role of physical activity and sedentary behavior on CRC risk in the Moroccan population. METHODS: A case-control study was conducted involving 1516 case-control pairs, matched on age, sex and center in five university hospital centers. A structured questionnaire was used to collect information on socio-demographics, lifestyle habits, family history of CRC, and non-steroidal anti-inflammatory drug (NSAID) use. Information on physical activity and sedentary behavior were collected by the Global Physical Activity Questionnaire (GPAQ). For each activity (work, household, and recreational activities), a metabolic equivalent (MET) was calculated using GPAQ recommendations. Conditional logistic regression models were used to assess the association between physical activity, sedentary behavior and the risk of overall CRC, colon cancer, and rectal cancer taking into account other CRC risk factors. RESULTS: High level of physical activity was associated with lower risk of rectal cancer, colon cancer, and overall CRC, the adjusted odds ratios (ORa) for the highest versus the lowest level of activity were 0.67 (95% CI: 0.54-0.82), 0.77 (95% CI: 0.62-0.96), and 0.72 (95% CI: 0.62-0.83), respectively. In contrast, sedentary behavior was positively associated with rectal cancer risk (ORa=1.19, 95% CI: 1.01-1.40), but was unrelated to colon cancer risk (ORa=1.02, 95% CI: 0.87-1.20). CONCLUSION: We found an inverse association between physical activity and CRC risk in the Moroccan population, and a positive association between sedentary behavior and rectal cancer risk. Considering that one-third of the total population studied had a sedentary lifestyle, these results may be used to improve strategies of public health suitable for Moroccan population.

OBJECTIVE: The aim of this study was to investigate the association between the consumption of foods and drinks from different food processing categories using the NOVA classification and CRC risk among Moroccan adults. METHODS: 1453 cases and 1453 matched controls aged at least 18 years and recruited from the 5 greater Moroccan regions were interviewed by trained investigators about their habitual diet using a standardized food frequency questionnaire (FFQ). Foods were categorized according to their degree of processing by the NOVA classification. Intakes of each food processing group were categorized into tertiles based on the distribution of controls with the lowest tertile considered as the reference category. Multivariable conditional logistic regression models were used to assess the association between each group and CRC risk (Odds Ratio (OR) and 95% Confidence Intervals (CI)), taking relevant confounders into account. RESULTS: High consumption of unprocessed or minimally processed foods (NOVA group 1) was significantly inversely (OR = 0.82, 95%CI = 0.72-0.93), while high consumption of ultra-processed foods and drink products (NOVA group 4) was significantly positively (OR = 1.40, 95% CI = 1.22-1.61) associated with CRC risk as compared to the lowest intake group. These results were similar for colon and rectum sub-sites. CONCLUSION: This is the first study to evaluate the association between the NOVA classification groups and CRC risk in an African country. Our results suggest that the consumption of ultra-processed foods and drink products may be associated with an increased risk of developing CRC, but longitudinal studies are needed to confirm these results.

INTRODUCTION: Women with breast cancer eligible for neoadjuvant therapy (NAT) present a disorder of biopsychosocial variables and alteration of their quality of life. They cope with this changing by adopting psychological adjustment strategies, either passive or active. This systematic review aims to investigate the psychological distress, coping strategies, and quality of life in breast cancer patients under neoadjuvant therapy. METHODS: Cochrane Library, PubMed, ScienceDirect, Scopus, Web of Science, and Wiley Online library represent the databases that were searched to identify relevant published articles until September 27, 2021. Full-text published articles, written in English and assessing the main outcomes (namely: psychological distress, coping strategies, and quality of life) in women with breast cancer under NAT will be included. Also, we will integrate papers dealing with the related bio psychosocial variables to the main variables. The paper selection, data extraction, and quality assessment of selected studies will be performed independently by two researchers, and disagreements will be resolved through discussions. We will bring together the results of all of the included studies to draw conclusions based on the body of evidence. The narrative approach will be adopted to analyze the results and conclusions extracted and we would perform quantitative groupings if we have similar data. ETHICS AND DISSEMINATION: Ethical approval is not required as the proposed systematic review will not use primary data. The results of this review will be disseminated through publication in a peer-reviewed journal and conference presentation(s). PROSPERO registration number: CRD42021230300.

Epidemiologic data support an association between diet and mutations in the Kirsten-ras (KRAS) gene involved in colorectal cancer (CRC) development. This study aimed to explore the associations between fat intake and KRAS mutations in codons 12 and 13 in cases of CRC in the Moroccan population. A multicenter case-series study nested in a large-scale Moroccan CRC case-control study was conducted. Among all CRC cases recruited, 151 specimens were available for the DNA mutation analysis. Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (Cis) for KRAS mutation status according to the fat intake variables. A KRAS mutation was detected in the CRC tumor of 34.4% of the patients among whom 65.4% had a single mutation at codon 12 and 34.6% had a single mutation at codon 13. Compared to low levels of consumption, a positive association was observed between high polyunsaturated fatty acids (PUFA) consumption (>16.9 g/day) and prevalence of KRAS mutations (OR = 2.15, 95% CI = 1.01-4.59). No statistically significant associations were observed for total fat, monounsaturated fatty acids, saturated fatty acids and KRAS mutations. The results of this study suggest that PUFA may be relevant in the etiology of CRC, possibly through the generation of G > A transitions at the KRAS oncogene. Further studies are needed to verify and explain this finding.

OBJECTIVES: The current study aimed to develop a modified Mediterranean diet (MMD) score adjusted to the southern Mediterranean countries' cultural specificities and to evaluate associations between adherence to this modified score and overweight/obesity risk in Moroccan adults. DESIGN: Population-based cross-sectional study. SETTING: Rural and urban areas of the five greatest provinces of Morocco. PARTICIPANTS: In total, 1516 participants were recruited between September 2009 and February 2017. Dietary assessment was obtained using a validated Moroccan FFQ. We constructed a MMD score focusing on twelve components. The MMD score ranged from 0 (no adherence to the traditional southern Mediterranean diet (MD)) to 12 (maximal adherence) and was categorised as low (scores 0-4), moderate (scores 5-7) and high (scores 8-12). RESULTS: Among the whole population, 754 (50·5 %) were women and 738 (49·5 %) were men, and the mean age was about 55·60 ± 13·70. In total, 58 % of participants were moderately active. Regarding educational level, 50·7 % were illiterate. The prevalence of overweight and obesity was 43·3 and 8·6 %, respectively. In multivariate analyses, close adherence to MMD (scores 8-12) was associated with reduced overweight/obesity risk (OR 0·61, 95 % CI 0·44, 0·84). CONCLUSION: The prevalence of overweight and obesity was very high among Moroccan adults. Adherence to the traditional southern MD may help prevent overweight and obesity.

BACKGROUND: Between 30 and 50% of colon tumors have mutations in the Kirsten-ras (KRAS) gene, which have a large nutritional attributable risk. Despite its high frequency in colorectal cancer (CRC), data to support specific associations between KRAS mutations in CRC and diet are sparse. Here, we conducted a systematic review to summarize the current epidemiological evidence on the association between various dietary factors and KRAS mutations. METHODS: PubMed, Science Direct, and Cochrane databases were searched for relevant studies published until December 31, 2019, using inclusion and exclusion criteria in accordance with PRISMA guidelines. We analyzed the studies to find associations between nutritional factors and CRC tumors with KRAS mutations in humans. RESULTS: We identified 28 relevant studies to include in this systematic review. In-depth analyses showed unclear associations between nutritional factors and KRAS mutations in CRC. Most epidemiological studies in the same nutrient or food often reported conflicting and/or inconclusive findings, whereas for some dietary factors, the results were homogeneous. CONCLUSIONS: Further research using a more robust prospective cohort study is needed to lend more credence to the epidemiological associations found between KRAS mutations and dietary factors.

BACKGROUND: Colorectal cancer (CRC) has been reported as the third most commonly diagnosed cancer worldwide and is currently considered as a major public health concern. A peak increase in incidence has been noted in economically transitioning countries like Morocco where industrialization started shifting from a traditional lifestyle and diet toward a more westernized diet and lifestyle. OBJECTIVE: This paper aims to present the protocol of a large-scale Moroccan case-control study that aims at investigating associations of diet, other lifestyle factors, and genetic traits with CRC risk in Morocco. METHODS: A case-control study was conducted between 2009 and 2017, including 3032 case-control pairs (1516 cases and 1516 controls) matched on sex, age, and center in 5 major public health hospitals in Morocco. Questionnaires on sociodemographic data, lifestyle, family history of CRC, and nonsteroidal anti-inflammatory drugs (NSAIDs) were completed by trained investigators during face-to-face interviews. In addition, participants completed a semiquantitative food-frequency questionnaire, developed to assess food intake in the Moroccan population. Information regarding genetic factors was recorded for cases, and paraffin blocks (with embedded tumor tissues) are available in 3 collaborating hospitals. Conditional logistic regression analysis is planned to assess associations between diet and CRC risk. Binary logistic regression is considered to predict associations between mutations and nutritional risk factors including only CRC case series. RESULTS: Altogether, 2966 cases-control pairs (1483 cases and 1483 controls) were considered eligible and included in this study. Both cases and controls did not differ significantly with respect to age (P=.36), sex (P=.51), center (P>.99), marital status (P=.30), and NSAID use (P=.08). However, participants in the control group were significantly more likely to have a high income level and live in urban areas and to have a high level of education than cases. CONCLUSIONS: This is the first study investigating potential risk factors of CRC such as lifestyle, diet, and genetic factors, originating from a southern Mediterranean country with low but increasing CRC prevalence. Identified risk factors allow the establishment of evidence-based preventive actions regarding nutrition and other lifestyle habits adapted to the Moroccan context. In brief, this study will promote cancer research and prevention in Morocco. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR1-10.2196/13998.
RESUMO
PURPOSE: The main objective of this study is to describe the association between the consumption of either traditional or modern dairy products or calcium intakes and the risk of colorectal cancer (CRC) in the adult Moroccan population. METHODS: A case-control study was conducted in five Moroccan hospital centers. The study was matched on sex, age (± 5 years) and center. Data were collected using validated food frequency questionnaire (FFQ) taking into account different types of Moroccan dairy products. Conditional logistic regression models were used to assess the association between dairy products consumption, calcium intakes and CRC risk subtypes. In all statistical tests, the significance level was set at 0.05. RESULTS: Among 1453 cases and 1453 matched controls, 50.7% were women and 49.3% were men. Milk ORb 0.84, 95% CI 0.74-0.96 and yogurt ORb 0.74, 95% CI 0.64-0.86 were inversely associated with CRC risk. Similar inverse associations were observed for traditional dairy products namely Lben ORb 0.77, 95% CI 0.67-0.88, Raib ORb 0.86, 95% CI 0.76-0.96 and Jben ORb 0.77, 95% CI 0.67-0.88. The dairy calcium intake was inversely associated to CRC overall ORb 0.83, 95% CI 0.74-0.93. CONCLUSIONS: Our study supports previous international evidence and suggests that individuals who have a high intake of either modern or traditional dairy products are at lower risk for CRC. These findings should be further confirmed by longitudinal data and studies investigating potential pathways involved.

The present study aimed to investigate associations between adherence to the recommendations on cancer prevention from the WCRF/AICR and colorectal cancer (CRC) risk in Morocco. Incident CRC cases (n = 1,516) and controls (n = 1,516) matched on age, sex and center, were recruited between September 2009 and February 2017 at five major hospitals located in Morocco. In-person interviews were conducted to assess habitual diet using a validated Food Frequency Questionnaire, physical activity and anthropometric measurements. Adherence to the WCRF/AIRC Recommendations was ranged from 0 (no adherence) to 6 (maximal adherence) and incorporating six WCRF/AICR components (food groups, physical activity and BMI). Multivariable odd ratios (ORA ) and 95% confidence intervals (CI) were calculated using conditional multivariate logistic regression models, with low adherence as referent, adjusting for potential confounding factors. Compared to those with the lowest adherence score, individuals in the highest WCRF/AICR score category had a statistically significant reduced risk for colon cancer (ORA = 0.63, 95% CI 0.53-0.76); rectal cancer (ORA = 0.52, 95% CI 0.43-0.63) and CRC overall (ORA = 0.58, 95% CI 0.51-0.66). For individual score components, when comparing the lowest with the highest adherence category, CRC risk was significantly lower in the highest adherence category for body fatness (ORA = 0.73; 95% CI 0.62-0.85), physical activity (ORA = 0.70; 95% CI 0.60-0.82), plant foods (ORA = 0.50; 95% CI 0.39-0.63) and red/processed meat (ORA = 0.81; 95% CI 0.71-0.92). Our analysis indicated that greater adherence to the WCRF/AICR recommendations for cancer prevention may lower CRC risk in Morocco.
