The COVID-19 pandemic has had a profound impact on mental health worldwide because of complex societal disruptions and neuropsychiatric consequences stemming from SARS-CoV-2 infection. All age groups have been affected by this pandemic, with particular focus on the vulnerabilities faced by children and adolescents who have experienced multiple stressors. These stressors involve various emotional, physiological, and behavioral challenges stemming from different factors, such as mandatory social distancing due to school closures, increased parental stress caused by the incessant spread of the pandemic, severe trauma from losing family members, a surge in cyberbullying linked to higher online activity, and a worrying rise in unreported incidents of child abuse. Empirical reports document an increase in suicidal tendencies and suicide attempts among adolescents during this crisis.
Objectives
This study conducted a comprehensive review of existing literature focused on the mental health of individuals aged 0-24 years in both pre-pandemic and pandemic eras. This study conducted comparative analyses to identify significant changes.
Methods
Adhering strictly to the PRISMA guidelines, we conducted comprehensive searches on Google Scholar and PubMed to identify peer-reviewed articles published in English.
Results
Most studies revealed deteriorating mental health conditions among adolescents and young adults following pandemic onset. These conditions were characterized by high rates of depression, anxiety, and psychological distress. Furthermore, several studies have identified a notable increase in negative emotions and heightened feelings of loneliness. Primary school children experienced a decline in attention span, emotional regulation, hyperactivity, and enthusiasm for academic engagement.
Conclusions
Based on the analysis of data from both the pre-pandemic and pandemic periods, it is evident that the COVID-19 pandemic had a detrimental impact on the mental well-being of children and young individuals. Therefore, it is crucial to identify the risk factors and protective measures linked with pandemics to enhance mental health resilience and better equip societies to cope with future health emergencies and other crises.
Suicide is a major public health concern, ranking among the leading causes of death worldwide.
Objectives
This study investigated the epidemiological features of collective suicide incidents in Morocco.
Methods
We performed a retrospective analysis of suicidal poisoning cases recorded by the Moroccan Poison Control Center (MPCC) over a 35-year period.
Results
During the study’s duration, the MPCC recorded 168 suicide cases. The mean age of those involved in these incidents was 23.9 years, with a female-to-male ratio of 1.57. The majority of those affected were adolescents and young adults, specifically between 15 and 34 years of age. Pesticides and drugs were the most commonly used methods of suicide and accounted for 31.1% and 20.1% of the cases, respectively. The majority of incidents occurred in the home environment and were primarily caused by oral exposure. The symptoms of poisoning varied according to the consumed substance, amount ingested, and elapsed time until medical treatment. The symptoms included disturbances in the neurological, gastrointestinal, respiratory, and cardiovascular systems. Of the 100 cases with known outcomes, one person died due to poisoning, whereas the remaining cases survived, although some enduring complications.
Conclusions
Suicide accounted for 1.3% of global mortality, ranking as the 17th most common cause of death in 2019, according to data from the World Health Organization (WHO). This trend emphasizes the urgent need for continuous efforts at all levels to address and mitigate this rapidly growing issue.
Teachers encounter various challenges that can significantly affect their professional well-being. This issue stands as of paramount importance, for it not only wields influence over job satisfaction but also carries weighty implications for the quality of education provided.
Objectives
This study aims to investigate the factors that affect teachers’ well-being, specifically examining the relationship between perceived stress, psychosocial risks, and burnout among public high school teachers in Tetouan, Morocco.
Methods
A questionnaire survey was conducted among 258 teachers, resulting in a response rate of 57%. Three distinct instruments were used to collect data: The Perceived Stress Scale (PSS) to evaluate perceived stress levels, the Job Content Questionnaire (JCQ) to assess psychosocial risks at work, and the Maslach Burnout Inventory (MBI) for burnout measurement. We examined the bivariate correlations among these three concepts.
Results
The results demonstrate significant associations among the studied factors. Perceived stress has a positive correlation with emotional exhaustion (r=0.51; p<0.01) and depersonalization (r=0.56; p<0.01), and a negative correlation with personal accomplishment (r=-0.31; p<0.01). Additionally, emotional exhaustion has a positive correlation with psychological demand (r=0.38; p<0.01). Depersonalization shows a positive correlation with psychological demand (r=0.18; p<0.05), but a negative correlation with decision latitude (r=-0.30; p<0.01) and social assistance (r=-0.24; p<0.01). Conversely, personal accomplishment presents a positive correlation with decision latitude (r=0.58; p<0.01) and social assistance (r=0.50; p<0.01).
Conclusions
This study underscores the importance of decision latitude and social assistance in promoting personal accomplishment and mitigating burnout among teachers. Nonetheless, further research is required to substantiate these results and determine the fundamental cause and effect relationships.
Suicide is a significant global public health issue that has a severe impact on children and adolescents.
Objectives
This study examined the epidemiological features of self-poisoning events among these groups in Morocco.
Methods
In this retrospective study, data on intentional poisoning cases among children under 15 years of age and adolescents aged 15-19 years were analyzed. The Moroccan Poison Control Center has reported these cases over a period of 34 years.
Results
During the study period, 7,111 deliberate self-poisoning cases were documented among children and adolescents, representing 30% of all reported self-poisoning cases (out of a total of 23,711 cases with known ages). The vast majority of the cases (80.8%) involved females, indicating a significant female-to-male ratio of 4.2. The patients had a mean age of 16.05 ± 2.10 years. Notably, drugs were the predominant method of self-poisoning, comprising 51.7% of the cases, followed by pesticides at 31.3%. The symptoms of poisoning manifested with significant variation, contingent on the type of toxin involved, the amount ingested, and the time passed before medical care was administered. Of the 4,711 cases with known outcomes, 144 (3.06%) were fatal. Nonetheless, the outcomes were favorable for the remaining cases, with or without lasting sequelae.
Conclusions
The ongoing prevalence of suicide and suicide attempts among children and adolescents is a prominent issue in public health. Our research emphasizes the crucial necessity to address suicide, as it remains one of the primary causes of mortality in young individuals.
Recent research has identified varying levels of burnout among teachers, particularly those in training. This condition is believed to be influenced by a combination of internal factors, such as psychological characteristics, and external factors, such as work-related pressures and the social environment.
Objectives
We examined the prevalence of burnout syndrome and assessed the potential risk factors associated with this condition. This study investigates the complicated correlation between academic burnout and interpersonal connections among trainee teachers in Morocco.
Methods
We used a comprehensive database generated from the Maslach Burnout Inventory-Student Survey (MBI-SS), a questionnaire designed specifically for this study, and validated for this context. We examined various dimensions of academic burnout to unravel the complexity of this connection. Our study analyzed individual, professional, and social factors within a cohort of 732 prospective teachers in Morocco during the 2021/2022 academic year.
Results
The findings revealed an intricate network of interrelated factors that contributed to the occurrence of academic burnout among trainee teachers. Significantly, the study highlighted the impact of interpersonal relationships on academic burnout. Trainee teachers who received support and positive interactions from colleagues and superiors showed significantly lower levels of academic burnout. Interpersonal relationships within the educational community also played a pivotal role in preventing burnout. Moreover, our multivariate analysis showed that certain sociodemographic factors,including age, gender, and prior educational experience, moderated the influence of interpersonal relationships on academic burnout.
Conclusions
This study significantly contributes to the comprehension of academic burnout in trainee teachers by emphasizing the vital role of interpersonal relationships in this context. The findings emphasize the necessity of interventions that enhance interactions within educational institutions to prevent academic burnout and promote a healthy learning environment for trainee teachers.
This study investigates the genetic and phenotypic aspects of early growth performance in the Murciano-Granadina goat breed, using data collected between 2016 and 2022 from a private dairy farm in Ghale-Ganj city, located in the southern area of Kerman province, Iran. Pedigree and data information were collected on several early body weight traits, including birth weight (BW), weaning weight (WW), average daily gain (ADG), Kleiber ratio (KR) and growth efficiency from birth to weaning (GE). Nine univariate animal models included direct additive genetic effects and different combinations of maternal effects were compared by using Akaike information criterion (AIC). Among the tested models, the best genetic analysis model for BW, included direct additive, maternal additive, maternal permanent and maternal temporary environmental effects. The best model for ADG, KR and GE included direct additive, maternal permanent and litter effects. For WW, the best model was determined to be one that included direct additive and maternal additive genetic effects. The estimated direct heritabilities were low values of 0.04, 0.07, 0.08, 0.05 and 0.07 for BW, ADG, KR, GE and WW, respectively. The estimates of genetic correlations among the studied traits were positive and low to high in magnitude which ranged from 0.11 for BW-KR to 0.91 for BW-GE. The phenotypic correlations ranged from 0.03 for KR-WW to 0.87 for ADG-KR. The positive correlations observed among the studied growth traits of the Murciano-Granadina goat breed indicate no negative genetic or phenotypic changes associated with selection for these traits.
Recent microfluidic experiments have evidenced complex spatio-temporal fluctuations in low-Reynolds-number flows of polymer solutions through lattices of obstacles. However, understanding the nonlinear physics of such systems remains a challenge. Here, we use high performance simulations to study viscoelastic flows through a hexagonal lattice of cylindrical obstacles. We find that structures of localized polymer stress – in particular birefringent strands – control the stability and the dynamics. We first show that, at steady state, strands act as a web of sticky flow barriers that induce channelization, multistability and hysteresis. We then demonstrate that a spontaneous destabilization of the strands drives the transition to unsteady flow with regimes of self-sustained oscillations, travelling waves and strand pulsations. We further show that these pulsations, which result from the destabilization of envelope patterns of stress with strands wrapped around multiple obstacles, are integral to the transition towards elastic turbulence in our two-dimensional simulations. Our study provides a new perspective on the role of birefringent strands and a framework for understanding experimental observations. We anticipate that it is an important step towards unifying existing interpretations of the nonlinear physics of viscoelastic flows through complex structures.
This study aimed to quantify a latent variable for body size (BS) in pigs by using five linear body measurements including body length (BL), body height (BH), chest width (CW), chest girth (CG) and tube girth (TG), and also to identify the most associated single nucleotide polymorphisms (SNP) and related genes with BS by using the genomic best linear unbiased prediction (GBLUP) based genome-wide association study (GWAS) or GBLUP-GWAS methodology. To perform a GWAS on the BS latent trait, we used a mixed linear model and identified a total of 53 significant SNPs. Additionally, we found that nine genes, including Rho GTPase activating protein 12 (ARHGAP12), transmembrane protein 108 (TMEM108), T-cell lymphoma invasion and metastasis inducing factor 1 (TIAM1), ras homologue gene family member B (RHOB), POU class 4 homeobox 1 (POU4F1), follistatin-related protein 4 (FSTL4), cellular communication network factor 2 (CCN2), beaded filament structural protein 2 (BFSP2) and attractin-like protein 1 (ATRNL1) were associated with the BS trait in pigs. These genes are involved in several biological processes, including the regulation of anatomical structure, morphogenesis, the regulation of cell size and growth. The results suggest that the identified SNP and related genes may play important roles in regulating the growth and development of pigs. The results imply that these genes could be promising candidates for further exploration of the underlying mechanisms of body size variation. Furthermore, the findings have significant practical implications for enhancing the efficiency and profitability of pig farming through genetic selection.
The flow of polymer solutions past solid obstacles or through porous media gives rise to rich physical phenomena over a wide range of spatial and temporal scales. Viscoelasticity, in particular, can induce a strong nonlinear response with an increase of flow resistance even for a solution whose viscosity decreases in simple shear flow. Various hypotheses have been proposed to explain this phenomenon but a clear picture of the pore-scale mechanisms involved and their impact upon larger scales is still lacking. Here, we show that localized zones of large polymeric stress, known as birefringent strands, drive the flow of an Oldroyd-B fluid through two-dimensional arrays of cylinders. Combining a recently developed numerical scheme with high performance computing, we find that these strands generate a complete reorganization of the flow with an increase of stagnation zones, a reinforcement of preferential paths and a splitting of flow channels. Furthermore, we show that this reorganization is the source of an increase in the viscous dissipation of the solvent and also that the stretching of polymer molecules in the strands is associated with entropy production. Both these phenomena yield a global increase in dissipation that can be directly linked to the increase of flow resistance. Our results demonstrate that the birefringent strands – not the elongational viscosity – drive the flow of viscoelastic fluids through porous media and that the increase of flow resistance can occur even at steady state, before the transition to elastic turbulence.
Records on growth and reproductive characteristics collected from 1993 to 2013 at the Breeding Station of Kermani sheep, south-east of Iran, were used for estimating genetic parameters related to parent-of-origin effects. The studied growth traits were birth weight (BWT), weaning weight (WWT), six-month weight (6MW), average daily gain from birth to weaning (ADG1), and average daily gain from weaning to six months of age (ADG2). The reproductive traits were litter size at birth per ewe lambing (LSB), litter size at weaning per ewe lambing (LSW), the sum of litter weight at birth per ewe lambing (LWB), and the sum of litter weight at weaning per ewe lambing (LWW). Models with and without imprinting (maternal and paternal) effects were compared by applying Akaike's information criterion (AIC). Maternal imprinting effects explained 14, 7, 24 and 5% of the phenotypic variances for BWT, WWT, 6MW and ADG1, respectively and their inclusion in the model decreased direct heritability estimates for BWT (from 0.07 to 0.05), WWT (from 0.29 to 0.23), 6MW (from 0.26 to 0.12) and ADG1 (from 0.20 to 0.17). Imprinting effects did not affect ADG2 and studied reproductive traits. The results indicated that a considerable proportion of the maternal imprinting effects overlap with direct additive genetic and maternal effects. Therefore, imprinting effects may be crucial for the genetic assessment of BWT, WWT, 6MW and ADG1 in Kermani sheep.
The goal was to study imprinting effects on birth weight (BW), weaning weight (WW), six months weight (W6), pre- and post-weaning growth rate (GRa and GRb), and pre- and post-weaning Kleiber ratio (KRa and KRb) in Baluchi and Makuie sheep breeds. Analyses were done in a two steps process. In the first step, each trait was analysed with a series of 12 univariate animal models, including different combinations of direct and maternal effects and the best model was selected by the AIC criterion. In the second step, three new models were fitted by adding either maternal imprinting effect, paternal imprinting effect, or both of them, respectively, to the best model already selected in the first step, and changes in AIC were monitored. (Co)variances between traits were estimated using bivariate analyses. In Baluchi sheep, for BW, WW and W6, estimates of maternal imprinting heritability (${\boldsymbol h}_{{\boldsymbol mi}}^2$) were 0.12 ± 0.02, 0.08 ± 0.01 and 0.09 ± 0.01, respectively. In Makuie sheep, paternal imprinting heritability (${\boldsymbol h}_{{\boldsymbol pi}}^2$) for BW, WW, W6, GRb and KRb were 0.17 ± 0.05, 0.8 ± 0.05, 0.38 ± 0.10, 0.71 ± 0.15 and 0.65 ± 0.13, respectively. In Baluchi sheep, strong maternal imprinting correlations were observed between BW and WW (0.93 ± 0.05), BW and W6 (0.80 ± 0.07) and WW and W6 (0.91 ± 0.02). In Makuie sheep, paternal imprinting correlations ranged from −0.97 ± 0.33 (BW-GRb) to 0.99 ± 0.47 (GRb-KRb). It was concluded that imprinting effects need to be included in the statistical model to increase the accuracy of genetic evaluation. However, to have accurate and reliable estimates of imprinting effects, the availability of large data sets and deep pedigrees are necessary.
Evidence-based diagnostic methods have clinical and research applications in neuropsychology. A flexible Bayesian model was developed to yield diagnostic posttest probabilities from a single person’s neuropsychological score profile by utilizing sample descriptive statistics of the test battery across diagnostic populations of interest.
Methods:
Three studies examined the model’s performance. One simulation examined estimation accuracy of true z-scores. A diagnostic accuracy simulation utilized descriptive statistics from two popular neuropsychological tests, the Wechsler Adult Intelligence Scale–IV (WAIS-IV) and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The final simulation examined posterior predictive accuracy of scores to those reported in the WAIS manual.
Results:
The model produced minimally biased z-score estimates (root mean square errors: .02–.18) with appropriate credible intervals (95% credible interval empirical coverage rates: .94–1.00). The model correctly classified 80.87% of simulated normal, mild cognitive impairment, and Alzheimer’s disease cases using a four subtest WAIS-IV and the RBANS compared to accuracies of 60.67–65.60% from alternative methods. The posterior predictions of raw scores closely aligned to percentile estimates published in the WAIS-IV manual.
Conclusion:
This model permits estimation of posttest probabilities for various combinations of neuropsychological tests across any number of clinical populations with the principal limitation being the accessibility of applicable reference samples. The model produced minimally biased estimates of true z-scores, high diagnostic classification rates, and accurate predictions of multiple reported percentiles while using only simple descriptive statistics from reference samples. Future nonsimulation research on clinical data is needed to fully explore the utility of such diagnostic prediction models.
Poems where a specifically iranian articulation of exile is expressed range over all the traditional genres and forms of Persian literature. Here, a ghazal, the most central lyrical genre, has been selected as the vehicle for such an articulation. Traditionally, the ghazal derives much of its unity from the mono-rhyme reflected in its form, often accompanied by a unique mood depicted through diverse and variegated images. Massoud Sepand's “The Air at Home” is one such poem, where the form has been utilized to communicate the poet's feelings about his homeland. While it opens with the image of the stifling air at home, the poem quickly turns to positing love for the country as a force that limits the ability of the speaker to overcome the exilic conditions.
Data of 2780 Markhoz kids originated from 1216 dams and 211 sires during 1993–2016 in Markhoz Goat Breeding Station, located in Sanandaj, Iran, were used. Traits investigated were body weights at birth, weaning, six-month age [six months weight (6MW)], nine-month age and yearling age [yearling weight (YW)]. Two considered multivariate models including standard multivariate model (SMM) and fully recursive multivariate model (FRM) were compared using deviance information criterion (DIC) and predictive ability measures including mean square of error (MSE) and Pearson's correlation coefficient between the observed and predicted values $(r(y,\hat{y}))$ of records. Spearman's rank correlation coefficients between posterior means of direct genetic effects of the studied traits of kids under SMM and FRM were also calculated across all, 50, 10 and 1% top-ranked animals. In general, FRM performed better than SMM in terms of lower DIC and MSE and also higher $r\lpar y\comma \;\hat{y}\rpar$. For all traits, the lowest MSE and the highest $r\lpar y\comma \;\hat{y}\rpar$ were obtained under FRM. All structural coefficients estimated under FRM were statistically significant except for that of 6MW on YW. Comparisons of Spearman's rank correlations between posterior means of direct genetic effects of kids for growth traits under SMM and FRM revealed that taking the causal relationships among the studied growth traits of Markhoz goat into account may cause considerable re-ranking for the animals in terms of estimated breeding values, especially for the top-ranked animals. It may be concluded that FRM had more plausibility over SMM for genetic evaluation of the studied growth traits in Markhoz goat.
Significant uncertainty remains regarding the exact timing and nature of subduction events during the closure of the Tethyan seas in what is now NW Iran. This study thus presents new geochemical compositions and U–Pb ages for a suite of volcanic rocks emplaced during Cenozoic volcanism in the west Alborz Magmatic Assemblage, which is commonly regarded as the back-arc of the Neotethyan magmatism in Central Iran. The subalkali basalts and andesites are dated to 57 ± 1.2 Ma, and are likely derived from a supra-subduction mantle wedge. Later, trachytic A-type rocks erupted from ∼42 to 25 Ma during an anorogenic (extensional) stage triggered by slab retreat and associated asthenospheric mantle influx. A-type melts were at least partly concurrent with lithospheric mantle magmatism implied by eruption of subalkali basalts–andesites around 26–24 Ma. Next, Amp-Bt trachybasaltic volcanism with high-Nb basaltic affinity at ∼19 Ma likely records slab deepening and slab partial melting, which reacted with the mantle wedge to produce the source material for the high-Nb basalts. Sr–Nd isotopic ratios for SE Ahar mafic as well as A-type rocks imply rather enriched mantle source(s). Some crustal contamination is implied by the presence of inherited zircons dominated by those derived from Neoproterozoic–Cambrian basement rocks and Carboniferous magmatism. Rhyolitic rocks with adakitic affinity probably mark the final volcanism in the study area. The adakitic rocks show crustal signatures such as high K and Th, probably formed as a consequence of higher temperature gradients, at crustal levels, imposed by both slab and mantle partial melts.
In this paper, hybrid control of central pattern generators (CPGs), along with an adaptive supper-twisting sliding mode (ASTSM) control based on supper-twisting state observer, is proposed to guard against disturbances and uncertainties. Rhythmic and coordinated signals are generated using CPGs. In addition, to overcome the chattering of conventional sliding mode, supper-twisting sliding mode has been applied. The ASTSM method triggers sliding variables, and its derivatives tend to zero continuously in the presence of the uncertainties. Moreover, to acquire maximum stability, the desired trajectory of the upper limb based on zero moment point criterion is designed.
Introduction: A physician handoff is the process through which physicians transfer the primary responsibility of a care unit. The emergency department (ED) is a fast-paced and crowded environment where the risk of information loss between shifts is significant. Yet, the impact of handoffs between emergency physicians on patient outcomes remains understudied. We performed a retrospective cohort study in the ED to determine if handed-off patients, when compared to non-handed-off patients, were at higher risk of negative outcomes. Methods: We included every adult patient first assessed by an emergency physician and subsequently admitted to hospital in one of the five sites of the CHU de Québec-Université Laval during fiscal year 2016-17. Data were extracted from the local hospital discharge database and the ED information system. Primary outcome was mortality. Secondary outcomes were incidence of ICU admission and surgery and hospital length of stay. We conducted multilevel multivariate regression analyses, accounting for patient and hospital clusters and adjusting for demographics, CTAS score, comorbidities, admitting department delay before evaluation by an emergency physician and by another specialty, emergency department crowding, initial ED orientation and handoff timing. We conducted sensitivity analyses excluding patients that had an ED length of stay > 24 hours or events that happened after 72 hours of hospitalization. Results: 21,136 ED visits and 17,150 unique individuals were included in the study. Median[Q1-Q3] age, Charlson index score, door-to-emergency-physician time and ED length of stay were 71[55-83] years old, 3[1-4], 48 [24,90] minutes, 20.8[9.9,32.7] hours, respectively. In multilevel multivariate analysis (OR handoff/no handoff [CI95%] or GMR[SE]), handoff status was not associated with mortality 0.89[0.77,1.02], surgery 0.95[0.85,1.07] or hospital length of stay (-0.02[0.03]). Non-handed-off patients had an increased risk of ICU admission (0.75[0.64,0.87]). ED occupancy rate was an independent predictor of mortality and ICU admission rate irrespectively of handoff status. Sensitivity and sub-group based analyses yielded no further information. Conclusion: Emergency physicians’ handoffs do not seem to increase the risk of severe in-hospital adverse events. ED occupancy rate is an independent predictor of mortality. Further studies are needed to explore the impact of ED handoffs on adverse events of low and moderate severity.
Electroconvulsive therapy (ECT) is widely and effectively used to treat psychiatric disorders. When electrodes are placed on both sides of the head on temporal bones it is unclear whether ECT affect on hearing system because hearing system situated in temporal lobe. Whereas these electrodes are placed on temporal bone and hearing system in TEMPORAL LOBE this study was designed.
Methods
We studied the effects of electroconvulsive shock on hearing system. Audiometric tests were performed in 15 adult patients with major depression under treatment with ECT before and 24h after ECT.
Results
Hearing was decreased at 24 hours after ECT about 5 db. Right ear was affected more and the most changes were observed at 8000 khz.
Conclusions
It appears that electroconvulsive shock has early effects on hearing system. Further studies should be performed with more cases and Delayed effects should be investigated.
In Morocco, as in other countries, the cannabis consumption by a great number of the population remains worrisome, in terms of its effects on “mental and physical” health and its social repercussions.
Objectives and aims
To determine the profile of the people poisoned by cannabis in Morocco in order to identify individuals and groups at high risk.
Methods
A retrospective study was conducted on chronic cannabis poisoning cases notified between 2000 and 2008 in the Morocco Poison Control Center.
Results
During the study period, three hundred and one regular users of cannabis (28 women and 273 men) were poisoned, constituting 34 cases on average per year. The clinical symptoms presented by victims are different, depending on the quantity of inhaled and absorbed psychoactive substances (especially THC) and the frequency and method of use. The average age of victims is 22 years. Among the 225 patients for whom the evolution is known, a 23-year-old man died. The rest of the patients’ condition has improved under gut decontamination.
Conclusions
The influence of consumption of the increasingly high doses of cannabis on the quality of life of young people justifies a public information, particularly young people for better prevention of using of this psychoactive product.
