作者： Yousra el Baki khalid Boutoial Abdelouahid Medaghri-Alaoui Laboratory of the Chemistry and Environment Faculty of Science and Technology Sultan Moulay Slimane University Beni Mellal Morocco Laboratory of the Engineering and Applied Technologies Higher School of Technology Sultan Moulay Slimane University Beni Mellal Morocco

The variations in both precipitation and temperature have far-reaching effects on agricultural activities and the accessibility of water resources. These climatic parameters are pivotal in determining the availability of both groundwater and surface water for agricultural use. The aim of this study was to evaluate the variations in climate parameters, focusing on precipitation and temperature, alongside changes in cultivated land area and crop yields in the Tadla area (Béni Mellal Khénifra region, Morocco);additionally, our research looks at the changes in water inflow into two dams and four aquifers. Trends were assessed over the period of 2010-2020 using the standardized precipitation index (SPI) method, as well as the parametric regression method and nonparametric Mann-Kendall and Sen’s slope test. This analysis can be a preliminary step in demonstrating the effects of climate variability on water resource availability and its adverse impacts on agriculture in the region. The results showed a decreasing trend for some yield crops despite the increase in the cultivated area. The results of the groundwater levels and inflow dams showed a significant upward evolution. The analysis of the obtained SPI values and temperatures has revealed a notable and consistent upward trendencies. This upward trajectory indicates that both the SPI values, which reflect precipitation patterns and the temperatures, have been on the rise over the examined period. These results prompt reflection on the effects of climate variability on water resources in the region and economic activities, particularly agriculture.

This article presents the direct torque control (DTC) strategy for the doubly fed induction motor (DFIM) connected to two three-level voltage source inverters (3LVSIs) with neutral point clamped (NPC) structure. This control method allows to reduce the torque and flux ripples as well as to optimize the total harmonic distortion (THD) of motor currents. The use of 3LVSI increases the number of generated voltage, which allows improving the quality of its waveform and thus improves the DTC strategy. The system modeling and control are implemented in Matlab/Simulink environment. The analysis of simulation results shows the better performances of this control, especially in terms of torque and flux behavior, compared to conventional DTC.

引用

Journal of Cancer Therapy 2022年第5期13卷 291-303页

作者： Kenza Benali Tayeb Kebdani khalid Hassouni Hanan el Kacemi Sanaa el Majjaoui Noureddine Benjaafar Department of Radiation Oncology National Institute of Oncology Rabat Morocco Faculty of Medicine Mohammed V University Rabat Morocco

Objective: To identify the informational needs of Moroccan women receiving intracavitary brachytherapy for locally advanced cervical cancer as part of a process to develop guidelines for quality patient-centered care. Methodology: A prospective, qualitative study with a phenomenological approach was carried out at the Brachytherapy unit of the National Institute of Oncology in Rabat, Morocco. Purposive sampling was used to recruit 31 patients undergoing high dose-rate brachytherapy for cervical cancer from July 2020 to August 2020. Semi-structured, one-to-one interviews were conducted by a female radiation oncologist in Arabic, guided by a theme list. The interviews were translated and a thematic analysis was performed. Results: Data saturation was achieved having interviewing 31 participants, aged 27 - 70 years. Findings on patients’ informational needs were the overarching theme and form the focus of this article. The informational needs included: providing patients with disease- and treatment-related information in their home language;adequate information concerning pre-treatment preparation, possible side-effects, and sexual intercourse;and providing patients with informative material adapted to their needs as standard procedure. Conclusion: This study has identified unmet women’s informational needs during brachytherapy for cervical cancer. Providing patients with sufficient and understandable information, adequate preparation before the procedure, more sensitive support during the procedure, and debriefing afterward could lessen feelings of fear and anxiety towards treatment delivery. Guidelines with a patient-centered approach could thus be developed to be used as a tool to assist members of multidisciplinary teams in providing quality care to this group of women.

Experiences of Women Receiving Multifraction High Dose-Rate Brachytherapy for Cervical Cancer: A Prospective Qualitative Study

引用

Journal of Cancer Therapy 2022年第6期13卷 311-322页

Objective: The aim of this study was to establish cervical cancer patients’ expectations and experiences during high dose-rate (HDR) intracavitary brachytherapy procedure, as part of a process to develop guidelines for quality patient-centered care. Methodology: A prospective, qualitative study with a descriptive phenomenological approach was used. Purposive sampling was carried out to recruit 31 women undergoing HDR brachytherapy for cervical cancer from June to August 2020 at the National Institute of Oncology in Rabat. Semi-structured, one-to-one interviews guided by a theme list were conducted by a female radiation oncologist in Arabic before, during and after treatment. The following aspects were discussed: expectations, experiences in the waiting room, in the treatment room, and suggestions for improvement. Data was transcribed, translated and thematic analysis performed. Results: Most of the patients felt unprepared and did not have a clear understanding of brachytherapy. Brachytherapy was a difficult experience causing fear and anxiety throughout treatment. Most women dreaded the procedure, before receiving the first treatment and even after having had one. Pain was a major problem for the participants. Some women compared this pain to childbirth, a process they preferred to brachytherapy. Patients agreed that the preventative medication received was not efficient to relieve the pain. Despite these negative experiences, patients were left with a positive outlook. Dialogue with the healthcare professionals, support from their family and fellow patients, envisaged outcomes and desires to heal were used to cope, whilst faith and spirituality gave them strength to endure the procedure. Conclusion: Women undergoing uterovaginal brachytherapy for cervical cancer experience pain and emotional distress. Providing patients with adequate information, more sensitive support during the procedure and debriefing afterwards could lessen feelings of fear and anxiety. Our fi

Journal of Cancer Therapy 2022年第6期13卷 323-330页

作者： Kenza Benali Tayeb Kebdani khalid Hassouni Sanaa el Majjaoui Hanan el Kacemi Noureddine Benjaafar Department of Radiation Oncology National Institute of Oncology Rabat Morocco Faculty of Medicine Mohammed V University Rabat Morocco

Background: Sarcomatoid carcinoma is a rare biphasic malignancy with an epithelial and mesenchymal component. Given its histological particularity, the diagnosis of this tumor still represents a challenge for pathologists and surgeons. Sarcomatoid carcinoma of the mandible is a very rare and aggressive entity. To date, only sporadic cases have been reported in the literature. Aim: To report a rare case of aggressive mandibular sarcomatoid carcinoma treated with radical surgery and adjuvant chemoradiation, and discuss the related literature. Case Report: We introduce a rare case of mandibular sarcomatoid carcinoma occurring in a 34-year-old woman. Treatment consisted of radical surgery and re-excision for positive margins, adjuvant radiation therapy (66 Gy in 33 fractions in simultaneous integrated boost delivered using Volumetric Modulated Arc Therapy) and Cisplatin-based concurrent chemotherapy. The tumor displayed aggressive behavior and high metastatic potential, causing tumour recurrence and extensive lung metastasis. Conclusion: Sarcomatoid carcinoma of the mandible is an extremely rare malignant entity, with a high tendency for local recurrence, distant metastasis. Treatment involves radical surgery and adjuvant chemoradiation, although the outcome and prognosis might be poor.

Evaluation of 3D-CRT and VMAT Radiotherapy Plans for Left Breast Cancer with Regional Lymph Nodes Irradiation

引用

Journal of Cancer Therapy 2023年第8期14卷 345-352页

作者： Houda Benmessaoud Hasnae Bouhia Halima Ahmut Sanaa el Majjaoui Hanane el Kacemi khalid Hassouni Tayeb Kebdani Department of Radiotherapy National Institute of Oncology of Rabat Faculty of Medicine and Pharmacy of Rabat Rabat Morocco

Introduction: Radiation therapy after breast surgery is an integral part of the treatment of early breast cancer. The goal of radiation therapy is to achieve the best possible coverage of the planning target volume (PTV), while reducing the dose to organs at risk (OARs) which are normal tissues whose sensitivity to irradiation could cause damage that can lead to modification of the treatment plan. In the last decade, radiation oncologist started to use the Intensity Modulated Radiotherapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) for irradiating the breast, in order to achieve better dose distribution and target dose to the PTV and OAR. The aim of this study is to compare 2 external radiotherapy techniques (VMAT vs 3D) for patients with node-positive left breast cancer. Patients and Methods: We randomly selected 10 cases of postoperative radiotherapy for breast cancer in our hospital. The patients are all female, the average age was 45.4 years old, and the primary lesions are left breast. The ANOVA test was used to compare the mean difference between subgroups, and the p value Results: Dose volume histogram (DVH) was used to analyze each evaluation dose of clinical target volume (CTV) and organs at risk (OARs). Compared to 3DCRT plans, VMAT provided more uniform coverage to the breast and regional lymph nodes. The max point dose for tVMAT was lower on average (106.4% for VMAT versus 109% for 3DCRT). OAR sparing was improved with tVMAT, with a lower average V17Gy for the left lung (27.91% for VMAT versus 30.04% for 3DCRT, p and lower for V28Gy (13.75% for VMAT versus 22.34% for 3DCRT, p = 0.01). We also found a lower V35Gy for the heart on VMAT plan (p = 0.02). On the contrary, dose of contralateral breast was lower in 3DCRT than VMAT (0.59 Gy vs 3.65 Gy, p = 0.00). Conclusion: The both types of plans can meet the clinical dosimetry demands of postoperative radiotherapy for left breast cancer. The VMAT plan has a better conformity, but 3CDRT can provide a lo
