Background: Cancer diagnosis disclosure is still a challenge for patients and health care providers in Saudi Arabia which may affect the patient’s ability to cope with a cancer diagnosis and it is subsequent treatments. Aim: This study is aimed to assess the effect of cancer diagnosis disclosure on patient’s coping self-efficacy at King Abdul-Aziz University Hospital, KSA-Jeddah. Methods: The data collected through a structured interview guided by coping Self-efficacy Scale (CSE) to measure the patients’ ability to perceive and cope effectively with their new diagnosis and the subsequent events related to it. It consists of 26 items subdivided into three factors. Distributed to adult patients above 18 years old who is newly diagnosed with cancer and willing to participate. Results: Among 102 participants enrolled in this study the relationship between age, marital status, educational level, income, and CSE showed no significant relationship, where p-value was higher than 0.05. Also, the relationship between diagnosis time and CSE show no significant relationship, where p-value was higher than 0.05, as no differences in CSE among patients who were diagnosed with cancer within two weeks, one month, one year ago, two years ago of interviewing them. The overall mean for their coping self-efficacy was moderate coping self-efficacy (3.86 ± 0.552). Conclusion: This study showed that the majority of cancer patients in this study had moderate coping self-efficacy and this could be explained by the strong faith, ideal living environment which involves family support, groups’ participation, reinforcement and daily activities which helped them to control their emotions and their abilities for coping with their experience of cancer diagnosis disclosure.

Newborn hearing screening(NHS) programs are essential to identify hearing loss early in life and to improve outcomes in children. In Saudi Arabia, the national NHS program has been operational since 2016;however, few studies have evaluated its status, and none have covered all provinces across the country. This cross-sectional retrospective study provides an overview of the program's status across all provinces, focusing on screening coverage rates, referral/fail rates, and follow-up procedures. In 2021, 199,034 newborns were screened, with a coverage rate of 92.6% and an overall referral/fail rate of 1.87%. These performance measures provide a foundation for future progress and improvements. This study highlights the importance of ongoing efforts to enhance the program's effectiveness and sustainability.

Characteristics of Gold and Its Mineralization Style in the Boulon Djounga Eastern Perimeter of Liptako Mining Company (Central Southwestern Niger)

引用

Natural Resources 2024年第1期15卷 28-50页

作者： Gambo Ranaou noura Kamayé Tourba Karimou Dia Hantchi Bouba Hassane Moussa Konaté Department of Geology Faculty of Science and Techniques Abdou Moumouni University Niamey Niger Department of Geology Faculty of Science and Techniques Dan Dicko Dankoulodo University Maradi Niger

The Boulon Djounga eastern perimeter is part of the Tiawa operating permit of the Société des Mines du Liptako (SML), located in the central southwestern part of Liptako (Niger). In this study, we used field data, Reverse Circulation (RC) surveys and chemical analyzes of gold to determine the characteristics of gold and its mineralization style. The eastern perimeter of Boulon Djounga is represented by a succession of metabasalts and metasediments both intersected by intrusions of quartz and dolerite dykes, and covered by sandstone and clayey rocks. Gold is present in low contents (0.00 - 0.30 ppm) in the sedimentary cover and in medium (0.30 - 1.00 ppm) or high contents (1.00 - 4.534 ppm) in the metasediments, and in the gray quartz veins and locally in the volcanics. It exists in a disseminated state or in a concentrated state in the surrounding areas in the form of discrete grains associated with sulphurous minerals (pyrite: FeS2, chalcopyrite: CuFeS2 or arsenopyrite: FeAsS). The presence of gold in the quartz veins, and the NE-SW and NW-SE orientations of the ore bodies suggest that the eastern Boulon Djounga gold mineralization would be established during a late magmatic extensive phase.

Tectonic Style Associated with the Doleritic Dykes of the Téra-Ayorou Pluton (Liptako, Western Niger)

引用

International Journal of Geosciences 2024年第8期15卷 567-581页

作者： Kamayé Tourba Gambo Ranaou noura Abdou Dodo Bohari Karimou Dia Hantchi Mallam Mamane Hallarou Hassane Ibrahim Maharou Yacouba Ahmed Moussa Konaté Groundwater and Georesources Laboratory Department of Geology Abdou Moumouni University Niamey Niger UMR of Water Sciences Mineral Resources Uses and Management Dan Dicko Dankoulodo University Maradi Niger

The doleritic dykes present in the Téra-Ayorou pluton crosscut the basement of the Nigerien Liptako and are part of the system of intrusive mafic dykes in the Paleoproterozoic domain of the Léo-Man ridge. In the previous work, emphasis was placed on the petrology, geochemistry and geochronology of the Liptako doleritic dykes. This study aims to analyze the tectonic style of intrusive doleritic dykes in the Téra-Ayorou pluton. The characterization of the deformation which affected the doleritic dykes of the Téra-Ayorou pluton is important for the evaluation of their economic potential. To this end, measurements of tectonic structure planes were taken in the field, and samples were taken from the chilled margin and cores of dolerite dykes, before being processed in the laboratory. Analysis of the tectonic structures collected revealed a brittle tectonic pattern, characterizing a phase of deformation subdivided into two episodes D1 and D2. Episode D1, with its subvertically dipping normal faults and simple N70˚ - N110˚ fractures, is compatible with N-S extension. On the other hand, episode D2, which created shear corridors by reactivation of pre-existing fractures and oriented N150˚ - N170˚, is associated with a WSW-ENE extension. These results open up prospects for the exploration of gold, uranium mineralization and diamonds in the north-west of Niger.

Bacterial cellulose (BC) is a versatile biomaterial with unique properties that make it promising for various biomedical applications, including wound healing. The extracellular matrix (ECM) plays a crucial role in wound healing, providing a structural scaffold and signaling cues for cell migration and proliferation. This study investigates the potential of BC as a scaffold for ECM production and its effect on in vivo wound healing. In this work, the bacterial cellulose fermentation process is modified by the addition of Green Propolis and Usnic acid to the culture medium and natural materials before the bacteria are inoculated. In vivo behaviour using natural membranes for regenerative medicine is presented and it is in edit. Overall, our findings demonstrate the potential of BC as a scaffold for ECM production and its beneficial effects on in vivo wound healing. BC-based dressings may offer a novel approach to promoting wound healing and tissue regeneration in clinical settings. Further studies are warranted to optimize BC-based therapies and explore their full potential in regenerative medicine.
