Practices for respecting the newborn's sleep-wake cycle: Interventional study in the neonatal intensive care unit.

Objectives: Premature newborns are exposed to a great deal of over-stimulation, which can affect their cerebral development. For better sleep, certain practices should be recommended. The aim of this study was to evaluate the effect of a professional training program on the improvement of practices promoting respect for the newborn's sleep-wake cycle. Materials and Methods: This was an interventional study with a longitudinal, single-group, and before-and-after design. The experimental design followed a three-stage time series: Eight months before, three months after, then eight months after intervention. It targeted a comprehensive sample of 66 professionals. It took place between October 2020 and March 2022 at the Neonatal Intensive Care Unit of the Hassan II University Hospital in Fez, Morocco. It was based on an observation grid and a self-administered questionnaire, validated and tested with a Cronbach's alpha reliability of 0.91. Results: The light environment showed significant differences between the 1st and 3rd step (3.3% vs. 45.0%; P = 0.02; confidence interval [CI] = 13.644-10.456) for knowledge and (13.3% vs. 78.3%; P = 0.01; CI = 14.412-10.888) for practices; the noise environment showed a positive improvement between the 2nd and 3rd intervention (31.7% vs. 41.7%; P < 0.001; CI = 5.954-2.913) for knowledge and (65.0% vs. 73.3%; P < 0.001; CI = 3.597-1.236) for practices, with an average of (8.98 ± 0.30-28.15 ± 0.48; CI = 3.806-1.094) between the 1st and 3rd step. Practices surrounding sleep and wakefulness reported significant improvement between the three periods (14.35 ± 0.22 vs. 18.10 ± 0.35 vs. 19.90 ± 0.35; P P < 0.001; CI = 4.647-2.853) for sleep and (13.25 ± 0.48 vs. 22.27 ± 0.59; P < 0.001; CI = 10.563-7.471) for wakefulness with statistically significant correlations between knowledge and practices (0.426**) for sleep and (0.606**) for wakefulness. Conclusion: The study demonstrated the positive impact of this sleep management and assessment program on the development of professional skills. Its implementation requires rigorous application of developmental support strategies for individualized care in neonatology.

Prevalence and associated factors of self-medication in worldwide pregnant women: systematic review and meta-analysis.

BACKGROUND: Self-medication during pregnancy is of great interest. The use of drugs during pregnancy requires a careful reflection on the benefits to the mother and the risks to the fetus. Selecting a drug or drugs for treating pregnant women can be difficult for clinicians owing to the various pharmacokinetic and physiological changes encountered during pregnancy. This systematic review and meta-analysis aimed to estimate the pooled prevalence of self-medication and associated factors among women during pregnancy. METHODS: Searches were carried out at PubMed, Science Direct, Web of Science, and Google Scholar. The quality of the studies and the risk of bias were analyzed using the Joanna Briggs Critical Appraisal Checklist for Analytical Cross-Sectional Studies instrument. The extracted data were tabulated and analyzed qualitatively and quantitatively through meta-analysis. RESULTS: The overall prevalence of self-medication among pregnant women was 44.50% (95% CI: 38.92-50.23). Subgroup analyses showed differences in self-medication prevalence influenced by region, county income, and study design. The Heterogeneity, assessed by the statistical test I2 varied from 96 to 99% and was statistically significant. The result of this funnel plot showed that the funnel plot was symmetry with p-value = 0.36, and there is no publication bias. CONCLUSION: The results obtained from this study showed that the prevalence of self-medication among pregnant women is relatively high. This requires effective measures and interventions to reduce self-medication. TRIAL REGISTRATION: ID = CRD42022312333 .

Rabies infection recognized as a psychosis: A misleading psychiatric presentation.

Rabies is a viral infection with a high mortality rate. Typical symptoms of rabies include hydrophobia, aerophobia, pharyngeal muscle spasms, and progressive paralysis. Psychiatric symptoms induced by rabies are not common. We report the case of a 26-year-old man in whom a quite typical clinical presentation of a brief psychotic disorder revealed rabies encephalitis.

The influence of physical activity, social relationships, and diet intake on depression: a case-series study.

This paper aims to investigate the three areas [diet, physical activity (PA), and social relationship] and their relationship with depressive disorders in the North African population. Study design: This is an observational cross-sectional study of 654 participants residing in the urban commune of Fez (n=326) and the rural commune of Loulja (n=328) in the province of Taounate. Participants were categorized into two groups: G1 without a current depressive episode and G2 with a current depressive episode. Risk factors, including locality, gender, marital status, age, parental status, employment status, tobacco use, alcohol consumption, social habits, and dietary patterns, were assessed. A multinomial probit model in Stata software was used to identify factors associated with depression occurrence in the population. Results: A total of 94.52% of the participants who engaged in PA did not experience a depressive episode (P=0.001). Additionally, 45.39% of the participants in our series were on a processed diet and presented with a depressive disorder (P=0.0001), the social contact (time spent with friends >1.5 h) remained strongly associated with reduced depressive symptoms when comparing the two groups (P=0.001). The results showed that being rural, a smoker, an alcohol user, and having no spouse significantly increased depression in participants. The coefficient of age was negatively related to the probability of the occurrence of age-related depression; however, this factor was not significant in the model. Thus, having a spouse and/or children and spending time with friends on a healthy diet significantly decreased depression in our population. Discussion: The converging evidence suggests that physical exercise, a stable social relationship, a healthy diet, and the use of PA can alleviate depression symptoms, but limited understanding and few studies have attempted to characterize or identify the neural mechanisms of these effects. Conclusion: Nonpharmaceutical interventions such as PA and dietary changes have proven to be effective treatments for depression, while maintaining positive social relationships can act as a protective factor, serving a prophylactic role in the prevention of depression.

Transcriptomic Analysis from Normal Glucose Tolerance to T2D of Obese Individuals Using Bioinformatic Tools.

Understanding the role of white adipose tissue (WAT) in the occurrence and progression of metabolic syndrome is of considerable interest; among the metabolic syndromes are obesity and type 2 diabetes (T2D). Insulin resistance is a key factor in the development of T2D. When the target cells become resistant to insulin, the pancreas responds by producing more insulin to try to lower blood glucose. Over time, this can lead to a state of hyperinsulinemia (high levels of insulin in the blood), which can further exacerbate insulin resistance and contribute to the development of T2D. In order to understand the difference between healthy and unhealthy obese individuals, we have used published transcriptomic profiling to compare differences between the WAT obtained from obese diabetics and subjects who are obese with normal glucose tolerance and insulin resistance. The identification of aberrantly expressed messenger RNA (mRNA) and the resulting molecular interactions and signaling networks is essential for a better understanding of the progression from normal glucose-tolerant obese individuals to obese diabetics. Computational analyses using Ingenuity Pathway Analysis (IPA) identified multiple activated signaling networks in obesity progression from insulin-resistant and normal glucose-tolerant (IR-NGT) individuals to those with T2D. The pathways affected are: Tumor Necrosis Factor (TNF), Extracellular signal-Regulated protein Kinase 1/2 ERK1/2, Interleukin 1 A (IL1A), Protein kinase C (Pkcs), Convertase C5, Vascular endothelial growth factor (Vegf), REL-associated protein (RELA), Interleukin1/1 B (IL1/1B), Triggering receptor expressed on myeloid cells (TREM1) and Nuclear factor KB1 (NFKB1) networks, while functional annotation highlighted Liver X Receptor (LXR) activation, phagosome formation, tumor microenvironment pathway, LPS/IL-1 mediated inhibition of RXR function, TREM1 signaling and IL-6 signaling. Together, by conducting a thorough bioinformatics study of protein-coding RNAs, prospective targets could be exploited to clarify the molecular pathways underlying the development of obesity-related type 2 diabetes.

Religiosity, stress, and depressive symptoms among nursing and medical students during the middle stage of the COVID-19 pandemic: A cross-sectional study in Morocco.

Background: Recent studies on nursing and medical students showed a higher prevalence of depression and stress than the general population. Religiosity and spirituality are common in Muslim countries and are usually used as a means of coping strategy for psychological and mental disorders. Objective: Our objective was to evaluate the association between religious actions, depressive symptoms, and stress among students of nursing education lasting 3 years and students from the first 3 years of medical education lasting 7 years. The study was conducted at Ibn Zohr University of Agadir, Morocco. Method: A sample of different stages of nursing and medical students was recruited. Religiosity was assessed by Muslim Belief into Action (M.BIAC) scale. The depressive symptoms and stress were, respectively, assessed by the Beck Depression Inventory (BDI-II) and Perceived Stress Scale (PSS). Results: Four hundred and thirteen students participated in this study. Our results showed a high prevalence of depressive symptoms (62.2%) and stress (66.8%). The depression scores were higher in the following subsample categories: students in the first 2 years of studies, female medical students, and nursing students with significant differences. The recorded religiosity was greater among students without depression compared to students with depression (p < 0.001). In the multivariate regression, the BIAC score demonstrated religiosity as neither a risk factor nor a protective factor of depression. Conclusion: Religiosity constitutes a protective factor of depression and stress among nursing and medical students. This should improve the student's ability to cope with stressful situations during their training. Prospective studies are needed to further investigate this association and how religiosity improves mental health. This would contribute to improved academic performance and wellbeing among medical and nursing students.

Social facilitation and bilingual cognitive advantage: Bridging social psychology and psycholinguistics.

This study examined the role of social context in the expression of the bilingual cognitive advantage in 145 bilingual university students. All participants mastered Arabic as their native language (L1), but half were highly proficient in French (high L2 group), whereas half were less proficient (low L2 group). A color-word Stroop test with incongruent, congruent and neutral stimuli was administered in single language blocks (Arabic or French words) or in a mixed block (Arabic and French words), either under social presence, or alone. Stroop interference was analyzed to assess the cost of resolving conflict in incongruent trials and was compared across groups and experimental conditions. If bilingualism comes with a cognitive advantage, a reduction of interference in high (vs. low) L2 proficient subjects is to be expected. Analysis revealed that interference was significantly reduced in high L2 group, but only under the single language condition. Furthermore, whereas social context and sex had no main effects, analysis revealed a significant 4-factor interaction between L2 proficiency, linguistic context, social context, and sex. Social presence further reduced interference (social facilitation) in high L2 proficient females, but not in males. Overall, the results suggest that mastering a second language comes with cognitive advantages which adapt dynamically to social and linguistic contexts in a sex-dependent manner. We argue that advancing bilingualism research requires more attention to the social environment.

The prevalence and associated factors of depression, anxiety, and PTSD among Moroccan medical doctors in the COVID-19 pandemic: a national study.

COVID-19 pandemic is facing healthcare professionals with unprecedented challenges, which might alter their mental health. We targeted assessing depression, generalized anxiety, and post-traumatic stress disorder (PTSD) of Moroccan medical doctors during the COVID-19 pandemic; this would allow identifying the associated factors. A cross-sectional national study was carried out on 1267 exposed and unexposed public health medical doctors to COVID-19 patients. The study was conducted between May 15 and 15 June 2020. An anonymous self-administered questionnaire was completed online voluntarily and randomly. We used the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder (GAD-7), and the PTSD Checklist for DSM­5 (PCL-5) to assess depression, generalized anxiety, and PTSD, respectively. The respondents' rate was 63.3%. The mean age was 30.97 ± 6.65 years old, and 59.3% (N = 751) were females with a sex ratio M/F of 0.68. The sample included 43.0% (N = 545) of COVID-19 frontline doctors. Among all participants, 31.5% (N = 400) had depression, 29.2% (N = 370) had generalized anxiety, and 21.7% (N = 276) had PTSD. The average scores of the PHQ-9, the GAD-7, and the PCL-5 were 7.79 (± 5.54), 6.12 (±5.72), and 18.58 (±17.62), respectively. The multivariate logistic regression showed that working in primary and secondary hospitals, moderate and high-stress perceptions, a chronic physical illness, and a family history of psychiatric disorder were independently associated factors of depression, generalized anxiety, and PTSD. The females expressed significantly more anxiety. Doctors living in a family consisting of member with chronic disease showed a significantly higher risk of PTSD. The security sense of contamination risk and low threat perception of COVID-19 were significantly protective factors of depression, anxiety, and PTSD. Moroccan medical doctors are in psychological distress. It is essential to preserve medical doctors' mental well-being health for a better fight against the COVID-19 pandemic through effective and targeted health policies.

Induced Depressive Disorder Following the First Dose of COVID-19 Vaccine.

INTRODUCTION: Several COVID-19 vaccines have been implemented. However, some side effects of the vaccine have been reported, which are sometimes very harmful. Reported cases and data are still very limited regarding the psychiatric side effects of the COVID-19 vaccine. To our knowledge, only one case has been reported. In this paper, we report the case of a patient who presented an acute depressive episode 24 hours after receiving his first dose of the BNT162b2mRNA vaccine. CASE REPORT: The case was a 26-year-old man with a history of Down syndrome with moderately good autonomy for daily routine tasks. The patient, who presented hypothyroidism at 10 years old and schizophrenia at 15 years old, was doing well before the vaccination and received his first dose of the BNT162b2mRNA vaccine. Twenty-four hours later, he presented depressive symptoms that resolved spontaneously after one week. Then, fifteen days later, the symptoms reappeared, and the episode lasted for 5 weeks. The patient received 10 mg/day of escitalopram besides his usual treatment. The depressive symptoms improved considerably by the second day of treatment. DISCUSSION: The presented case illustrated significant diagnostic challenges, especially when taking into account the sequential relationship between the COVID-19 vaccine and the occurrence of depressive symptoms. A single case of depression has been reported after the administration of the COVID-19 vaccine. Scientific evidence suggests the important role of the immune system in the pathophysiology of various psychiatric disorders, including depression. CONCLUSION: Health professionals must take into consideration the potential psychiatric side effects even being rare so far, especially in vulnerable subjects. Further studies are required to establish the causal effects of depressive symptoms occurring during the weeks following the COVID-19 vaccine bolus injection.

Self-medication practice among pregnant and postpartum women attending the regional hospital center of Souss Massa, Morocco: a cross-sectional study.

Background: Self-medication among pregnant women represents a serious risk to the mother's and child's health. It is a global concern that requires careful attention from professionals in healthcare. In Morocco, there is a lack of available data on self-medication and predicting variables among pregnant and postpartum women. The purpose of this study was to determine the incidence of self-medication and the factors that contributed to it among pregnant and postpartum women in the Sous Massa Regional Hospital. Methods: A cross-sectional study was conducted using a pretested questionnaire among 420 pregnant and postpartum women who were attending the regional hospital center of the Sous Massa region from April to December 2022. Statistical analysis was performed using Jamovi Software. The logistic regression analysis was used to determine the significance of the association between the outcome and independent variables. Results: The research enrolled 420 pregnant and postpartum women. During the current pregnancy, 24.8% of the women used self-medication. The leading common causes/symptoms that necessitate self-medication among pregnant and postpartum women were Anemia (84.8%), epigastralgia (16.8%), vomiting, pyrosis (15.2%), and urinary and vaginal infections The therapeutic families concerned with self-medication practice were Analgesics (41.4%), Antacids (20.3%), antimicrobials (13.5%), and Vitamin supplements (9%). According to the findings, the most frequent sources of information were pharmacists (45.6%), followed by physicians (44.3%). The primary reasons given by respondents for self-medication were the need for rapid release (51.7%), previous treatments with the same drugs (31.7%), and 20% reported difficulty of access to healthcare professionals. Out of 95.9% of the participants reported that they knew the dangers of self-medication and 96% of them were informed and received information about the dangers and contraindications of self-medication during pregnancy. This was significantly statistically associated with self-medication respectively with p-value = 0.031 and p-value = 0.005. Conclusion: The findings of the present study provide an initial awareness of the state of self-medication among pregnant and postpartum women attending the regional hospital centers. It is recommended that healthcare professionals increase their interventions to improve the consciousness of pregnant women; this might require implementing suitable strategies to regulate the commercialization, delivery, and use of conventional medications.

Evaluation of rural-urban patterns in dietary intake: A descriptive analytical study - Case series.

Purpose: This article aimed to evaluate the different epidemiological aspects of the population (Fez-Meknes region), expose the secular trends of the food habits related to it, present the basic concepts and mechanisms of food in urban and rural areas in the Fez-Meknes region, and finally to analyze the results in the light of a literature review. Materials and method: A survey was conducted among a representative sample of the urban and rural population in the Fez-Meknes region (654 people aged 15 years and over, of which 326 people reside in the urban commune of Fez and 328 in the rural commune of Loulja in the province of Taounate). Results: The results are, a difference between the two urban and rural groups concerning the rhythm of taking meals outside the home (P < 0,001); the average frequency of consumption of certain foods according to social class (p < 0,001); the frequency of food consumption per week of legumes, olive oil, fermented milk, and tea is more increased than that recorded in the urban environment (p < 0,001). On the other hand, the quantification of the consumption of sweet products, dairy products, and whole grains did not conclude a significant difference between the two study environments (p > 0,05). Discussion: Changing dietary patterns over the past few decades, including more shift work, more meals eaten outside the home or family setting, and more irregular eating patterns, including skipping breakfast and eating late at night. Conclusion: A disparity in eating habits between urban and rural areas was noted. It would be necessary to act judiciously on the environmental factors by encouraging the Moroccan populations to maintain, as much as possible, their good traditional habits, and to reinforce the new good food habits.

Analytical methods for honeybee venom characterization.

The discovery of new drugs has benefited significantly from the development of research in venomics, increasing our understanding of the envenomation processes. It has been previously reported that honeybee venom (HBV) exhibits several pharmacological activities such as anti-inflammatory, antibacterial, antimutagenic, radioprotective, and anticancer activity and may inclusively act as a complementary treatment for SARS-CoV-2. It composition consists mainly on melittin, phospholipase A2, and apamin but other constituents such as hyaluronidase, mast cell degranulating peptide and secapin are also relevant for its bioactivity. However, and because HBV is not officially recognized as a drug, until now, the international community did not establish quality standards for it. To uncover its exact composition, and boost the discovery of HBV-derived drugs, a significant number of techniques were developed. In this review, a relevant overview of the so far published analytical methods for HBV characterization is organized with the aim to accelerate its future standardization. The literature search was performed within PubMed, Google Scholar, and Science Direct by selecting specific documents and exploring HBV evaluation.

Are Patients with Schizophrenia Reliably Reporting their Cannabis Use? An African Cross-sectional Study.

BACKGROUND: Most studies of the prevalence of cannabis use among patients with schizophrenia used a self-report as declared by the patient himself. We hypothesize that patients with schizophrenia did not tell the truth and might underreport their use for many reasons to be discussed later. Indeed, the under-report of cannabis use among these patients can affect the effectiveness of their treatment. AIMS: To assess the degree of agreement between the prevalence values obtained from patients' reports and the results of the toxicological tests. METHODS: A cross-sectional study was carried out on 403 patients with schizophrenia. A sociodemographic, psychiatric history and illicit drug use profile was performed for each patient. We assessed the patients with the Positive and Negative Syndrome Scale (PANSS), Calgary Depression score (CDSS), Barratt Impulsiveness Score (BIS-10) and Medication Adherence Rating Scale (MARS). The consumption of cannabis used was confirmed with MINI International Neuropsychiatric Interview (MINI-DSM IV) and using toxicological analysis. RESULTS: Among the 403 patients who consented to give their urine samples, 49.1% (198/403) tested positive for cannabis, and 41.41% (82/198) underreported their use. The sensitivity and specificity of the questionnaire were 0.58 and 0.74. Based on the comparison between sociodemographic and psychiatric history data of patients who self-report and underreport their cannabis use, no significant difference was observed except for the duration of cannabis use and the score on the medication adherence scale. Moreover, it was found that impulsivity, PANSS score, CDSS score, and the type of schizophrenia are not involved in predicting the underreporting of cannabis use. CONCLUSION: The rate of patients who under-report cannabis use is important. Therefore, toxicological analysis is becoming relevant for identifying drug use among schizophrenic patients and in the addictive comorbidity research field.

Heavy and Chronic Cannabis Addiction does not Impact Motor Function: BOLD-fMRI Study.

OBJECTIVE: The aim of this paper is to demonstrate the impact of heavy and chronic cannabis use on brain potential functional control, reorganization, and plasticity in the cortical area. METHODS: 23 cannabis users were convened in 3 user's groups. The first group included 11 volunteers with an average of 15 joins/day; the second group included 6 volunteers with an average of 1.5 joins/day; the third group included 6 volunteers with an average of 2.8 joins/week. Besides, a 6 healthy volunteers (control group). All healthy and cannabis users underwent identical brain BOLD-fMRI assessment of the motor function. Besides, neuropsychological and full biological assessments were achieved. RESULTS: BOLD-fMRI maps of motor areas were obtained, including quantitative evaluation of the activations in the motor area. Besides, statistical analysis of various groups was achieved. CONCLUSION: Chronic cannabis addiction of varying use strength by groups of heavy, moderate, low dose, and zero doses are shown to have systematically equivalent effects on the control of brain motor function. Indeed, the BOLD-fMRI shows a remarkable sensitivity to minimal brain plasticity and reorganization of the functional motor control of the studied cortical area, and such varionation was not shown. Specific elucidation of the cannabis effect mechanisms in this unique function should clarify further protective pharmacological effects. This might illuminate the use of neuronal resources to prepare processes for pharmacological use and pharmaceutical forms. This suggests exploring any potential cannabis pharmaceutical form in diseases involving motor impairments.

People with spinal cord injury in Morocco: results from the very first systematic data collection.

PURPOSE: To report on the methodology, participant characteristics, and associations of four most frequent environmental barriers with health conditions, general health and quality of life (QoL) in the very first systematic data collection in people with spinal cord injury (SCI) in Morocco. MATERIALS AND METHODS: We obtained data from 385 participants of the cross-sectional Moroccan SCI community survey (MorSCI). We used descriptive statistics to describe participant characteristics and regression models to investigate associations of the five most frequently reported environmental barriers with health conditions (secondary conditions, pain intensity, mental health), general health and QoL. RESULTS: The most frequently reported environmental barriers were "lack of public services" (92.5%), "financial strain" (93.0%), restricted access to "public transportation" (85.5%), "public places" (83.9%) and "private places" (84.7%). People who perceived those factors as barriers also reported more secondary conditions, higher pain intensity, lower mental health, lower general health, and lower QoL. CONCLUSIONS: This study on Moroccans with SCI found that environmental barriers detract from health and QoL. Given that environmental barriers are potentially modifiable, policy interventions present powerful tools to reduce barriers and potentially increase health and QoL in this vulnerable population.IMPLICATIONS FOR REHABILITATIONPublic policy on the construction of transportation and public places is important to make the physical environment accessible for wheelchair users to support their participation in society.The provision of adequate rehabilitation services and specialized post-acute rehabilitation units for people with SCI in Morocco is urgently needed, not only to contribute to health and QoL but also to contribute to their abilities to overcome environmental barriers.Adequate state services including universal health coverage and access to rehabilitation services and assistive devices or adapted tools must be a priority on the policy level to facilitate activities of daily living and reduce barriers.Improving the skills and knowledge of health professionals in SCI rehabilitation and guide policy makers to promote patient education and self-advocacy in the meantime, may help reduce the gap between needs of people with SCI and available support.

Current state of cannabis use, policies, and research across sixteen countries: cross-country comparisons and international perspectives.

INTRODUCTION: Varying public views on cannabis use across countries may explain the variation in the prevalence of use, policies, and research in individual countries, and global regulation of cannabis. This paper aims to describe the current state of cannabis use, policies, and research across sixteen countries. METHODS: PubMed and Google Scholar were searched for studies published from 2010 to 2020. Searches were conducted using the relevant country of interest as a search term (e.g., "Iran"), as well as relevant predefined keywords such as "cannabis," "marijuana," "hashish," "bhang "dual diagnosis," "use," "addiction," "prevalence," "co-morbidity," "substance use disorder," "legalization" or "policy" (in English and non-English languages). These keywords were used in multiple combinations to create the search string for studies' titles and abstracts. Official websites of respective governments and international organizations were also searched in English and non-English languages (using countries national languages) to identify the current state of cannabis use, policies, and research in each of those countries. RESULTS: The main findings were inconsistent and heterogeneous reporting of cannabis use, variation in policies (e.g., legalization), and variation in intervention strategies across the countries reviewed. European countries dominate the cannabis research output indexed on PubMed, in contrast to Asian countries (Thailand, Malaysia, India, Iran, and Nepal). CONCLUSIONS: Although global cannabis regulation is ongoing, the existing heterogeneities across countries in terms of policies and epidemiology can increase the burden of cannabis use disorders disproportionately and unpredictably. There is an urgent need to develop global strategies to address these cross-country barriers to improve early detection, prevention, and interventions for cannabis use and related disorders.
