In the last few decades, addressing the global challenge of implementation of strategies for renewable energy and energy efficiency has become ***, since 2009, has made a steadfast commitment to sustainability, with a particular focus on advancing the development of renewable energy resources. A comprehensive strategy has been formulated, centering on utilizing the country's energy potential to drive progress in this vital sector. Morocco is considered a country with abundant thermal water, indicating deep reservoirs with significant hydrothermal potential. Geothermal zones were selected based on the abundance of hot springs where water temperatures were high and geothermal gradients were significant. The abundance and importance of hot springs, combined with recent volcanism and ongoing non-tectonic activity linked to alpine orogeny, strongly suggest that these regions are promising reservoirs for geothermal energy. This great potential also extends to neighboring countries. In northeast and south Morocco, the temperature of thermal water ranges from 26 to 54℃. This study serves as an inclusive review of the geothermal potentialities in Morocco.

Cancers is a leading cause of mortality among transplant recipients. The most common cancers are skin tumors. Glioblastoma is the most frequent brain tumor in adults aged 45 - 70 years. It accounts for 12% - 15% of all intracranial tumors. It is characterized by its rapid development and poor prognosis. We report the case of a cerebral glioblastoma in a kidney transplant recipient. Clinical case: Mr G.R, 44 years old caucasian patient who underwent kidney transplantation. Immunosuppressive treatment included cyclosporine, mycophenolate mofetil and methylprednisolone. Creatinine levels after transplantation remained stable at 11 mg/L (96.8 μmol/l) with an estimated glomerular filtration rate (eGFR) of 77 ml/min/1.73m2 after a 15 years of follow-up. A grade IV right fronto-callossal cerebral glioblastoma was diagnosed in our patient. EBV PCR was negative. Therefore, he underwent 25 sessions of radiotherapy combined with oral chemotherapy using temozolomide. One month later, the patient died due to cerebral edema with subfalcine herniation. Conclusion: This is a case of cerebral glioblastoma in a kidney transplant recipient, a population considered at risk for tumor development due to immunosuppressive treatment. This emphasizes the need for a lifelong surveillance and, more importantly a better balance between graft function preservation and the risks associated with immunosuppressants.

Kaposi sarcoma is a neoplasm caused by human herpesvirus 8 (HHV8) that most commonly affects immunosuppressed patients. The skin is the most affected area, but other sites can be involved such as the lung, digestive tract and lymph nodes. The classical presentation involves a violaceous skin lesion that can be small or hidden, leading to a delay in diagnosis. We report a clinical case of a kidney transplant patient, who presented, 14 months after kidney transplant, with unilateral edema of the inferior member and cutaneous rash misdiagnosed and taken initially for erysipelas. The diagnosis of Kaposi’s sarcoma was retained, on a lymph node biopsy of an inguinal adenopathy. The evolution was marked by a local and general improvement after systemic chemotherapy, reducing Tacrolimus and discontinuation of Mycophenolate mofetil. Graft function remained stable during the follow-up.

Môle Saint-Nicolas, like all other communes in the Republic of Haiti, faces increasing climate variability, impacting agricultural production and water resources. Consequently, there is a pressing need for adaptation to these climatic changes. This research aims to showcase the adaptation strategies deployed by farmers to cope with the increasing climate variability. Surveys were conducted through group and individual discussions with a randomly selected cohort of 150 farmers. Two types of analysis were performed: quantitative and qualitative. The quantitative data analysis was conducted using Statistical Package for the Social Sciences (SPSS) software. The findings reveal that farmers have perceived changes in rainfall patterns, temperature, wind, and their environment. These changes manifest as irregular rainfall, higher temperatures, prolonged drought periods, violent winds accompanied by rain, premature cessation of rains, and reduced flow from water sources. In response, the most common adaptation strategies adopted include selecting new cultivars, early-maturing varieties, crop rotation and diversification, canal dredging, new soil preparation methods, upstream water source protection, and micro-watershed management. The significance of this research lies in its contribution to enhancing farmers’ adaptive capacities by alerting stakeholders in the irrigated perimeters about the consequences of climate change, thereby incorporating the real needs of farmers in future projects.

Post infectious Glomerulonephritis (PIGN) in renal allograft is a rare entity. Only a few Cases have been described in the literature. The post streptococcal glomerulonephritis is the classic example in native kidney. A wide variety of organism has been associated with PIGN in renal allograft such as Staphylococcus, Cytomegalovirus and Polyomavirus. We describe one case of Infection associated glomerulonephritis due to Echericha Coli, developed 5 years after kidney transplantation, in 47 years old female patient. The Clinical presentation was characterized by a peripheral edema and high blood pressure, and biological tests showed a nephrotic syndrome, an acute kidney injury, a consumption of Complement fractions. The renal biopsy revealed a diffuse endocapillary cell proliferation with preponderant deposits of C3. Total recovery was achieved 4 months after Methyprednisolone pulse and Cyclophasphamid with antimicrobial treatment.

Objective: To study the prevalence of bisphosphonate-related osteonecrosis of the jaw (BRONJ) and to determine the risk factors associated with the occurrence of this pathology. Method: An observational retrospective study was conducted in the Department of Oncology, Rheumatology, and Maxillofacial Surgery of Ibn Rochd University Hospital, Casablanca. The study utilized complete medical records from 2014 to 2022 and included consultations of patients receiving bisphosphonates (BPs) in July and September 2022. Statistical analysis was performed using SPSS version 16.0. Results: Our study population comprised 104 patients, of whom 91% were women and 49% were over 65 years old. Seventy-two percent of patients had a general pathology. Among them, 64 patients were treated with zoledronate, 43 with alendronate, and the remainder with risedronate, ibandronate, and pamidronate. The most common indications for treatment were bone metastasis following breast cancer (29.8%) and osteoporotic fractures (19.2%). Sixty-seven patients received intravenous (IV) treatment;only 10.5% exhibited good oral health. Fifty percent of patients underwent dental treatment, primarily tooth extractions. Osteonecrosis of the jaw (ONJ) was diagnosed in 1.9% of patients, predominantly in stages 1 and 2. Conclusion: Second and third-generation bisphosphonates are more strongly associated with the development of ONJ. Risk factors include monthly IV administration, poor oral health, comorbidities such as diabetes, medications like corticosteroids, invasive dental procedures, and not only oncological conditions but also rare indications such as bone algodystrophy. Nevertheless, our observed prevalence of 1.9% aligns with international rates ranging from 0.8% to 12%. However, most of the studies that have been carried out have been retrospective studies with insufficient numbers of patients. Further prospective epidemiological studies based on standardized protocols with rigorous and appropriate follow-
