RESUMEN

This paper reports the case of a spontaneous rupture of a non-scarring gravid uterus seen four days after vaginal delivery and provides an update on this rare pathology, which can be functionally and vitally life-threatening. Uterine rupture of a healthy gravid uterus can occur as a result of structural abnormalities of the uterine tissue framework or uterine parietal fragility due to pathological phenomena such as septic states. On admission, the clinical picture is generally that of an acute abdomen with a hypogastric origin, with or without hemodynamic instability and an altered general condition, depending on the presence of an underlying advanced uterine infection. Medical imaging, mainly ultrasound and CT scan with iodine contrast, enables visualization of the uterine breach and a precise assessment of the damage. Surgery is the treatment of choice for repairing the breach and ensuring hemostasis. This case study sheds light on this pathology, familiarizing us with its clinical and radiological picture, as well as its post-treatment prognosis.

RESUMEN

INTRODUCTION: The Stroke Impact Scale 3.0 appears to be a promising measure of health-related quality of life for stroke patients. However, the lack of a cross-cultural adaptation in Arabic dialect may limit its use in the Moroccan context. The objective of this study was to carry out a transcultural adaptation and pilote validation of the Stroke Impact Scale 3.0 in Moroccan Arabic dialect, commonly called « Darija ¼. PATIENTS AND METHODS: A cross-sectional design was used for this study. The cross-cultural adaptation of the SIS 3.0 scale into Moroccan Darija was carried out following the guidelines proposed by Beaton et al (2000). Ceiling and floor effects were calculated for all scales. The internal consistency of multi-item scales was assessed using Cronbach's α coefficient. Convergent and divergent validity were evaluated using the Multi-Trait Multi-Method Correlation Matrix method. RESULTS: A total of 102 patients, with a mean age of 49 ± 12.9 years, participated in the study. The results revealed that the dimensions of the translated scale had no floor effect and no ceiling effect. The internal consistency of SIS 3.0 (Cronbach's alpha) was calculated, and all dimensions had good reliability, above the threshold of 0.70 (between 0.705 and 0.945). The results showed that the dimensions and their own items had correlation coefficients greater than 0.4, with good convergent and divergent validity. CONCLUSION: The darija version appears to be culturally acceptable with good psychometric properties and can be used to measure the quality of life of stroke survivors in Morocco.

RESUMEN

BACKGROUND: Human immunodeficiency virus- positive women have an increased risk of precancerous lesions and invasive cervical cancer. This study aims to identify the level of awareness/knowledge and attitudes toward cervical cancer among women living with Human immunodeficiency virus in the region of Souss-Massa in southern Morocco.  Methods: This is a multicenter cross-sectional study conducted in the Souss-Massa region (southern Morocco) among women attending Human immunodeficiency virus treatment and care centers between March 2022 and September 2022. A questionnaire was used for data collection. The Chi-square test and logistic regression were deployed to identify factors associated with cervical cancer awareness among the target population. RESULTS: A total of 494 respondents to the questionnaire, 440 (89.1%) are aware of cervical cancer. Nevertheless, 405 (82.0%) and 369 (74.7%) were unaware of cervical cancer risk factors and symptoms, respectively. Only 125 (25.3%) knew the exact frequency of cervical cancer screening among Human immunodeficiency virus positive women, whereas 221 (44.7%) had ever been tested for cervical cancer. Factors associated with women's awareness of cervical cancer are as follows:  level of education (adjusted Odds Ratio = 3.78 with 95% CI, 1.23-11.65), time since diagnosis of Human immunodeficiency virus (adjusted Odds Ratio = 4.31 with 95% CI, 1.12- 16.52), knowledge of women with cervical cancer (adjusted Odds Ratio = 6.30 with 95% CI, 1.87-21.18) and heard the pap- smear/visual inspection with acetic acid (adjusted Odds Ratio = 4.92 with 95% CI, 2.35-10.33). CONCLUSION: The general knowledge of seropositive women regarding cervical cancer remains very low, which justifies the integration of cervical cancer prevention services with Human immunodeficiency virus care, and pinpoints the crucial role of patient education.

RESUMEN

Coastal zones are fragile and complex dynamical systems that are increasingly under threat from the combined effects of anthropogenic pressure and climate change. Using global satellite derived shoreline positions from 1993 to 2019 and a variety of reanalysis products, here we show that shorelines are under the influence of three main drivers: sea-level, ocean waves and river discharge. While sea level directly affects coastal mobility, waves affect both erosion/accretion and total water levels, and rivers affect coastal sediment budgets and salinity-induced water levels. By deriving a conceptual global model that accounts for the influence of dominant modes of climate variability on these drivers, we show that interannual shoreline changes are largely driven by different ENSO regimes and their complex inter-basin teleconnections. Our results provide a new framework for understanding and predicting climate-induced coastal hazards.

RESUMEN

PURPOSE: Distance learning describes any learning based on the use of new multimedia technologies and the internet to allow students to acquire new knowledge and skills at a distance. This study aimed to determine satisfaction levels with distance learning and associated factors among nursing and health technician students during the coronavirus disease 2019 pandemic in Morocco. METHODS: An descriptive study was conducted between April and June 2022 among nursing and health technician students using a self-administered instrument. The student satisfaction questionnaire consists of 24 questions categorized into 6 subscales: instructor, technology, course setup, interaction, outcomes, and overall satisfaction. It was based on a 5-point Likert scale, ranging from 1 (strongly disagree) to 5 (strongly agree). Univariate and multivariate logistic regression analyses were conducted to identify factors associated with student satisfaction during distance learning. RESULTS: A total of 330 students participated in this study, and 176 students (53.3%) were satisfied with the distance learning activities. A mean score higher than 2.8 out of 5 was obtained for all subscales. Multiple regression analysis showed that students' year of study (adjusted odds ratio [aOR], 2.34; 95% confidence interval [CI], 1.28­4.27) and internet quality (aOR, 0.47; 95% CI, 0.29­0.77) were the significant factors associated with students' satisfaction during distance learning. CONCLUSION: This study highlights the satisfaction level of students and factors that influenced it during distance learning. A thorough understanding of student satisfaction with digital environments will contribute to the successful implementation of distance learning devices in nursing.

RESUMEN

INTRODUCTION: Stigma underlies the violation of certain social, economic, and cultural rights of patients with schizophrenia, including their access to treatment and care. Measurement of stigma remains as complex and multifaceted as the phenomenon itself. Several measurement tools are available to assess the prevalence, intensity and qualities of stigma. The aim of the study was to carry out a cross-cultural adaptation of the Explanatory Model Interview Catalogue (EMIC), in the Moroccan Arabic dialect commonly known as "Darija". PATIENTS AND METHOD: The study was conducted in three psychiatric departments of public hospitals in the Souss-Massa region, located in southern Morocco. For the diagnosis of schizophrenia, the study was based on the decisions of the psychiatrists practicing at the study sites. The cross-cultural adaptation in Moroccan Darija of the stigma scale developed by Michel Weiss in the EMIC was carried out according to the six-step scientific method developed by Dorcas et al. RESULTS: Cronbach's alpha (internal consistency) was 0.845. Convergent validity determined by Pearson's coefficient showed a significant inter-item correlation and the intra-class correlation coefficient (test-retest) was 0.975 (0.993; 0.991). The item added in relation to the COVID-19 situation presented psychometric values similar to the others. CONCLUSION: The Darija version is culturally acceptable and can be used to approach the phenomenon of stigmatization in Morocco.

RESUMEN

COVID-19 is one of the worst outbreaks in infectious disease history. Through a succession of significant preventative and control interventions, Morocco has accumulated pandemic control experience. This study examines the available evidence on lessons learnt from the COVID-19 pandemic management experience in Morocco. Social lockdown measures have helped restrain the exponential spread of new cases. These interventions appear to be reasonably successful. Their effectiveness must be confirmed by an assessment of other factors. This experience can help all countries develop effective pandemic prevention and control measures.

RESUMEN

Coasts are areas of vitality because they host numerous activities worldwide. Despite their major importance, the knowledge of the main characteristics of the majority of coastal areas (e.g., coastal bathymetry) is still very limited. This is mainly due to the scarcity and lack of accurate measurements or observations, and the sparsity of coastal waters. Moreover, the high cost of performing observations with conventional methods does not allow expansion of the monitoring chain in different coastal areas. In this study, we suggest that the advent of remote sensing data (e.g., Sentinel 2A/B) and high performance computing could open a new perspective to overcome the lack of coastal observations. Indeed, previous research has shown that it is possible to derive large-scale coastal bathymetry from S-2 images. The large S-2 coverage, however, leads to a high computational cost when post-processing the images. Thus, we develop a methodology implemented on a High-Performance cluster (HPC) to derive the bathymetry from S-2 over the globe. In this paper, we describe the conceptualization and implementation of this methodology. Moreover, we will give a general overview of the generated bathymetry map for NA compared with the reference GEBCO global bathymetric product. Finally, we will highlight some hotspots by looking closely to their outputs.

RESUMEN

BACKGROUND: Gliomas are the most common primary tumors of the central nervous system (CNS). The most common subtype of glioma in adults is grade IV astrocytoma, known as glioblastoma (GB) multiforme. Despite advances in treatment, GB remains a lethal tumor with a poor prognosis, and patients face serious quality of life (QoL) issues. Its poor prognosis is a real public health problem. The present study aimed to determine the exact neurocognitive status and QoL in patients with GB in the Mediterranean region and the different predictive factors responsible for their deterioration. METHODS: This systematic review was conducted in accordance with PRISMA guidelines. The protocol was registered in the PROSPERO (Identifier: CRD42020188936). The following databases have been independently searched by 2 authors: PubMed, Science Direct, Scopus and Google Scholar. RESULTS: Thirteen studies were selected (n=13). Four studies (n=4) focused solely on cognitive assessment, five studies (n=5) focused on quality-of-life assessment, and four (n=4) were simultaneously assessed QoL and neurocognitive status. The majority of studies in this review use (Mini-Mental State Examination, MMSE) for an overall cognitive assessment (n=5), other studies use specific batteries for an in-depth assessment of cognitive functions (n=3). The study revealed several affected functions: short and long-term memory, executive functions (EFs), and visuo-constructive abilities. Scale of European Organization for Research and Treatment of Cancer and the Functional Assessment of Cancer Therapy are among the most widely used instruments for assessing QoL. For factors influencing neurocognitive status and QoL, the present review found that: The Karnofsky Performance Scale (KPS), tumor location, age, sex and type of treatment are the most identified. Other studies have reported other factors, such as tumor progression, development of emotional distress, and coping strategies adopted. DISCUSSION: We conclude that there were many changes in patients with GB during the course of the disease and that most of them were related to age and disease progression. The use of coping strategies based on social support has a positive impact on the QoL.

RESUMEN

Laser drilling has been widely used in various application fields because of advantages such as environmental friendliness, scalability, non-contact, etc. Nevertheless, it still has some drawbacks. One of the most concerning is the taper degree caused by the ablation process resulting from a laser Gaussian beam. In this study, we utilize a nanosecond double-pulse laser (at 532 nm) to experimentally acquire a series of holes on stainless thin plates. With the double-pulse train, the taper degree of a drilled hole becomes half of that drilled by using a single-pulse train. Different combinations of the power component of the two pulses for the double-pulse laser have been investigated to earn the optimum power ratio of the two pulses. For instance, by using a double-pulse laser train with a repetition rate of 5 kHz and a total power of 8 W, we observe that the optimized combination of the two pulses is 2 W and 6 W. Furthermore, we theoretically analyze the variations of the density, temperature, and pressure around the processing area during both the double-pulse and single-pulse laser processing based on a constrained interpolation profile procedure. The theoretical results show that drilled holes with smaller taper degree can be realized by using the double-pulse approach. Our results have great potential in laser drilling and precision laser machining.

RESUMEN

BACKGROUND: The aims of this study were to determine the survival of anatomic total shoulder arthroplasty with uncemented metal-backed (MB) glenoid components with a polyethylene (PE) insert in primary osteoarthritis, to assess the reasons for revision surgery, and to identify patients and diagnostic factors that influence failure rates. METHODS: Between 1994 and 1999, 165 patients (mean age, 68 years) with primary osteoarthritis were treated with anatomic total shoulder arthroplasty using an uncemented MB/PE glenoid component. Outcomes were assessed both clinically and radiologically with a minimum of 2 years of follow-up. A prosthetic survival curve was constructed with the end point defined as either partial or complete revision, using 100% confidence intervals. RESULTS: Survival rate free of revision was 46% (100% confidence interval, 32%-54%) at 12 years. At a mean follow-up of 8.5 years (range, 2-16 years), revision was required in 61 patients (37%); 80% of shoulders undergoing revision (49 of 61) had evidence of PE wear. Glenoid loosening (because of osteolysis secondary to wear debris), soft tissue deficiency, and prosthetic instability were the most common modes of failure. Younger patients and biconcave glenoids (with posterior humeral subluxation) have a negative effect on implant survival. Proximal humerus osteolysis was significantly more frequent in shoulders with PE wear. Exchange of the PE insert (with conservation of the MB tray) was possible in only 3% of the revised shoulders. CONCLUSION: Uncemented MB glenoid resurfacing is not a viable long-term therapeutic option because of accelerated PE wear leading to early revision surgery. Conservation of the MB tray with reinsertion of a new PE insert is rarely possible because of glenoid bone loss, implant loosening, soft tissue deficiency, and prosthetic instability. Younger patients and biconcave glenoids have a negative effect on implant survival.

RESUMEN

This paper is devoted to the characterization of polymer-filler interfaces by thermoporosimetry using water as a probe. Composites of EVA filled with aluminium hydroxide with high filler content for the required fire retardant properties have been studied. After water sorption at 90 °C, the composites have been analyzed by thermoporosimetry using water as a morphological probe. This technique first allowed studying the influence of the filler content and the specific surface area on the water uptake. The study with drying steps and two molecular probes (water and cyclohexane) has highlighted that water is confined at the interface and thus thermoporosimetry is a powerful tool to characterize interfaces in EVA-ATH composites.

RESUMEN

The oil extracted from the bean of Balanites aegyptiaca was characterized, and its photochemical and thermal stabilization were evaluated. The chemical composition was determined using gas chromatography (GC), revealing that the oil is very rich in unsaturated fatty acids (72% omega-6 and omega-9). The photochemical stability was assessed by subjecting it to artificially accelerated photo-aging and then examining the changes using infrared spectroscopy. The thermal stability was studied at six different temperatures ranging from 130 to 200°C and monitored in situ by differential scanning calorimetry (DSC). The kinetic parameters (EA and k) describing the thermal degradation of this oil were calculated. It has been shown that the antioxidants present in the oil delay the oxidation process (induction period). The degradation of the Toogga oil was compared with that of oleic and linoleic fatty acids. In addition, the degradation of the Toogga oil extracted with hexane was compared to that of the neat oil.

RESUMEN

The crystallization of PLA-silane surface-treated ZnO nanocomposites was investigated by DSC and compared to that of neat PLA. Several modes of crystallization were considered: isothermal and non-isothermal cold crystallization and also isothermal and non-isothermal melt crystallization. The kinetics of cold crystallization were studied using different methods, namely the Avrami and Ozawa-Flynn-Wall models, to calculate activation energies and kinetic constants. In contrast to what is typically observed when the foreign particles are added in a polymer matrix, the silane surface-treated ZnO delayed the crystallization of PLA and made it more difficult to start. The nucleation activity of the ZnO nanoparticles, ϕ, was calculated and found to be greater than 1 (ϕ = 1.7). This indicated that ZnO played an anti-nucleating role in the crystallization of PLA nanocomposites. This effect has been linked mainly to the interactions between the silane groups onto the surface of nanoparticles and PLA macromolecules. These interactions which reduce the mobility of polymer chains have been evidenced by rheological experiments.
