PurposeThe high prevalence of COVID-19 has had an impact on the Quality of Life (QOL) of people across the world, particularly students. The purpose of this study was to investigate the social, lifestyle, and mental health aspects that are associated with QOL among university students in Lebanon.MethodsA cross-sectional study design was implemented using a convenience sampling approach. Data collection took place between November 2021 and February 2022, involving 329 undergraduate and graduate students from private and public universities. Quality of life was assessed using the Quality-of-Life Scale (QOLS). Descriptive statistics, Cronbach’s alpha, and linear regression-based methods were used to analyze the association between QOL and socio-demographic, health-related, lifestyle, and mental health factors. The significance level for statistical analysis was predetermined at α = 0.05.ResultsThe study participants’ average (SD) QOL score was 76.03 (15.6) with a Cronbach alpha of 0.911. QOL was positively associated with importance of religion in daily decisions (β = 6.40, p = 0.006), household income (β = 5.25, p = 0.017), general health ratings (β Excellent/poor = 23.52, p <0.001), access to private counseling (β = 4.05, p = 0.020), physical exercise (β = 6.67, p <0.001), and a healthy diet (β = 4.62, p = 0.026); and negatively associated with cigarette smoking (β increased = -6.25, p = 0.030), internet use (β ≥4 hours = -7.01, p = 0.005), depression (β = -0.56, p = 0.002) and stress (β = -0.93, p <0.001).ConclusionIn conclusion, this study reveals the key factors that positively and negatively influence students’ quality of life (QOL). Factors such as religion, higher income, and a healthy diet improve QOL, while depression, stress, excessive internet use, and cigarette smoking negatively impact it. Universities should prioritize initiatives like physical activity promotion, affordable nutritious options, destigmatizing mental health, counseling services, and self-help interventions to support student well-being and enhance their QOL.

Erythrodermic psoriasis (EP) is a rare form of psoriasis but has a high mortality and morbidity rate. The management of erythrodermic psoriasis includes prevention of complications and administration of immunosuppressant drugs such as methotrexate. This article reports the case of a 37-year-old man with complaints of red, scaly spots almost all over his body since the past month. Initially, the red spots only appeared on the right and left arms and legs. On dermatological examination found lesions on >90% of the patient's total body area in the form of erythematous patches, well-defined, irregular shape and covered with thick scales, there was onycholysis of the toenails, and the Karvslek phenomenon in the patient. Based on the history and physical examination, the patient was diagnosed with erythrodermic psoriasis with a PASI score of 60.2. The patient received oral methotrexate therapy 7.5 mg/week, folic acid once daily, cetirizine 10 mg twice daily, and topical therapy with desoximetasone cream 0.25%. Methotrexate is taken alternately with a single dose of 2.5 mg. Evaluation of patients at 1 month after therapy showed improvement in clinical symptoms with reduced subjective symptoms followed by a change in the PASI score to 45.8. Proper diagnosis and management as well as monitoring for side effects of medication can reduce morbidity and prevent complications from EP.

Investigate Spectroscopic Experimental and Theoretical Model for Hemoglobin Nanoscale Solution
Authors: Naif Hanan Auda , Abbas Asaad M. , Al-Kadhemy Mahasin Fadhil Hadi 
Published: July 2023

In the current study, haemoglobin analytes dissolved in a special buffer (KH2PO4(1M), K2HPO4(1M)) with pH of 7.4 were used to record absorption spectra measurements with a range of concentrations from (10-8 to 10-9) M and an absorption peak of 440nm using Broadband Cavity Enhanced Absorption Spectroscopy (BBCEAS) which is considered a simple, low cost, and robust setup. The principle work of this technique depends on the multiple reflections between the light source, which is represented by the Light Emitting Diode 3 W, and the detector, which is represented by the Avantes spectrophotomer. The optical cavity includes two high reflectivity ≥99% dielectric mirrors (diameter 25mm, radius of curvature 100mm) and a quartz cuvette 1 cm to put the samples in the system. This system is also composed of some lenses, aires, and optical fibres to transfer the light from the light source to the optical cavity and after that to the detector. This setup is considered ~3-fold more sensitive when it is compared with another spectroscopic technique as it reduces the effect of noise due to fluctuations in the light intensity. Additionally, the theoretical study estimated the absorption spectra of the haemoglobin concentrations using Table Curve 2D software. The absorption spectra curve was fitted using a suitable curve-fitting equation for these spectra, which was represented by the Gaussian function. The similarity of the theoretical and practical spectra demonstrated that the estimated models can replace the experimental measurements, which leads to a reduction in the cost and time required for the absorption spectroscopy measurements

Abstract
Background
The purpose of this 2-arm parallel study was to compare the rate of en-masse retraction using friction versus frictionless mechanics. Anchorage loss, molar rotation, changes in the incisor position, and pain was additionally assessed.
Methods
Twenty-eight patients were randomly allocated into two en-masse retraction groups using friction or frictionless mechanics. Eligibility criteria included maxillary dentoalveolar protrusion requiring maxillary 1st premolars extraction with maximum anchorage. Randomization was done in a 1:1 allocation ratio into either friction (A) or frictionless (B) groups. In group A, power-chains of 200 g retraction force on 0.017” x 0.025” st.st archwire were utilized. Group B comprised of T-loops using the same gauge TMA archwires and comparable force. Measurements were made on scanned 3D models, superimposed on one another, as well as pre-treatment and post-retraction cephalograms.
Results
It was a single-blinded study where the outcome assessors were blinded. For the friction group, the rate of retraction was 0.63 ± 0.18 mm per month, with a total retraction of 4.04 ± 1.41 mm spanning over 6.42 ± 1.08 months. The frictionless group was 0.75 ± 0.23 mm per month with a total retraction of 4.13 ± 1.44 mm, over 5.67 ± 1.5 months.
Conclusion
Frictionless mechanics was only slightly faster than friction mechanics regarding the rate of retraction, not enough to make a significant difference between the two groups. Frictionless mechanics is not recommended in cases with great anchorage needs, as the molars tend to move and rotate mesially during retraction, regardless of the presence of miniscrews. Trial registration: Trial was registered on clinicaltrials.org, with the reference number NCT04902430.
Feeding habits of the invasive Atlantic blue crab Callinectes sapidus (Decapoda, Brachyura, Portunidae) in a temperate European estuary

Published: July 2023

AbstractThe Atlantic blue crab, native from the east coast of the American continent, is a portunid, estuarine crab that has been recently considered invasive in many areas of the European and African continents, being cited in the Guadalquivir estuary in 2017 for the first time. The feeding habits of the Atlantic blue crab were studied as predictor of food web interactions and potential impacts in the study area. Depending on the availability of food,C. sapiduscan adapt to a diverse resource utilization in the Guadalquivir estuary. The main consumed preys were fish, molluscs, and crabs, but they also consumed sediments and vegetation, although in smaller quantities and with a lower frequency. Diet composition was very generalist, and no seasonal or sexual effects were detected. However, diet seems to be more diverse in summer, while in winter blue crabs seem to switch trophic strategies to cannibalism or scavenging on fishing discarded nets. In addition, sexual dimorphism of chela and different spatial distribution seem to diverge the diet composition between males and females during the different sampled seasons. This requires the establishment of many diverse trophic interactions between the Atlantic blue crab and the native food web, which could lead to future impacts on the native community. Consequently, we believe that prey monitoring and control over this non-native species should be considered a priority for the management and conservation of the Guadalquivir estuary. Other methodological approaches as laboratory experiments and feeding habits predictors should be considered as future studies to better describe the trophic behaviour in the wholeC. sapidusspecies.

Abstract
Traditional game is a game that is played simply, which contains noble values originating from its predecessors. Dexterity is a mandatory skill in playing traditional games, because in general traditional games are carried out outdoors or in open fields which require body movements from the players. Therefore, there is a need for a movement to preserve traditional games for the younger generation, seeing that currently children and adolescents prefer games that are accessed virtually which results in laziness in moving and social interaction among the younger generation.

BackgroundThe role of adaptive immune responses in long COVID remains poorly understood, with contrasting hypotheses suggesting either an insufficient antiviral response or an excessive immune response associated with inflammatory damage. To address this issue, we set to characterize humoral and CD4+ T cell responses in long COVID patients prior to SARS-CoV-2 vaccination.MethodsLong COVID patients who were seropositive (LC+, n=28) or seronegative (LC-, n=23) by spike ELISA assay were recruited based on (i) an initial SARS-CoV-2 infection documented by PCR or the conjunction of three major signs of COVID-19 and (ii) the persistence or resurgence of at least 3 symptoms for over 3 months. They were compared to COVID patients with resolved symptoms (RE, n=29) and uninfected control individuals (HD, n=29).ResultsThe spectrum of persistent symptoms proved similar in both long COVID groups, with a trend for a higher number of symptoms in the seronegative group (median=6 vs 4.5; P=0.01). The use a highly sensitive S-flow assay enabled the detection of low levels of SARS-CoV-2 spike-specific IgG in 22.7% of ELISA-seronegative long COVID (LC-) patients. In contrast, spike-specific IgG levels were uniformly high in the LC+ and RE groups. Multiplexed antibody analyses to 30 different viral antigens showed that LC- patients had defective antibody responses to all SARS-CoV-2 proteins tested but had in most cases preserved responses to other viruses. A sensitive primary T cell line assay revealed low but detectable SARS-CoV-2-specific CD4 responses in 39.1% of LC- patients, while response frequencies were high in the LC+ and RE groups. Correlation analyses showed overall strong associations between humoral and cellular responses, with exceptions in the LC- group.ConclusionsThese findings provide evidence for two major types of antiviral immune responses in long COVID. Seropositive patients showed coordinated cellular and humoral responses at least as high as those of recovered patients. In contrast, ELISA-seronegative long COVID patients showed overall low antiviral responses, with detectable specific CD4+ T cells and/or antibodies in close to half of patients (52.2%). These divergent findings in patients sharing a comparable spectrum of persistent symptoms raise the possibility of multiple etiologies in long COVID.

BackgroundThere is increasing evidence that patients with retinal detachment (RD) have aberrant brain activity. However, neuroimaging investigations remain focused on static changes in brain activity among RD patients. There is limited knowledge regarding the characteristics of dynamic brain activity in RD patients.AimThis study evaluated changes in dynamic brain activity among RD patients, using a dynamic amplitude of low-frequency fluctuation (dALFF), k-means clustering method and support vector machine (SVM) classification approach.MethodsWe investigated inter-group disparities of dALFF indices under three different time window sizes using resting-state functional magnetic resonance imaging (rs-fMRI) data from 23 RD patients and 24 demographically matched healthy controls (HCs). The k-means clustering method was performed to analyze specific dALFF states and related temporal properties. Additionally, we selected altered dALFF values under three distinct conditions as classification features for distinguishing RD patients from HCs using an SVM classifier.ResultsRD patients exhibited dynamic changes in local intrinsic indicators of brain activity. Compared with HCs, RD patients displayed increased dALFF in the bilateral middle frontal gyrus, left putamen (Putamen_L), left superior occipital gyrus (Occipital_Sup_L), left middle occipital gyrus (Occipital_Mid_L), right calcarine (Calcarine_R), right middle temporal gyrus (Temporal_Mid_R), and right inferior frontal gyrus (Frontal_Inf_Tri_R). Additionally, RD patients showed significantly decreased dALFF values in the right superior parietal gyrus (Parietal_Sup_R) and right paracentral lobule (Paracentral_Lobule_R) [two-tailed, voxel-level p &lt; 0.05, Gaussian random field (GRF) correction, cluster-level p &lt; 0.05]. For dALFF, we derived 3 or 4 states of ALFF that occurred repeatedly. There were differences in state distribution and state properties between RD and HC groups. The number of transitions between the dALFF states was higher in the RD group than in the HC group. Based on dALFF values in various brain regions, the overall accuracies of SVM classification were 97.87, 100, and 93.62% under three different time windows; area under the curve values were 0.99, 1.00, and 0.95, respectively. No correlation was found between hamilton anxiety (HAMA) scores and regional dALFF.ConclusionOur findings offer important insights concerning the neuropathology that underlies RD and provide robust evidence that dALFF, a local indicator of brain activity, may be useful for clinical diagnosis.

BackgroundSuicidal and non-suicidal self-injurious behaviors are among the leading causes of death and injury in adolescents and youth worldwide. Mobile app development could help people at risk and provide resources to deliver evidence-based interventions. There is no specific application for adolescents and young people available in Spanish. Our group developed CALMA, the first interactive mobile application with the user in Spanish, which provides tools based on Dialectical Behavioral Therapy to manage a crisis of suicidal or non-suicidal self-directed violence with the aim of preventing suicide in adolescents and youth.MethodsTo test the effectiveness, safety and level of engagement of the CALMA app in people aged 10 to 19 who are treated in mental health services of two public hospitals, we will conduct a parallel-group, two-arm randomized controlled trial. Participants will be assessed face-to-face and via video call at four timepoints: day-0 (baseline), day-30, day-60, and day-90. A total of 29 participants per group will be included. Change in the frequency of suicidal and non-suicidal self-injurious behaviors will be compared between groups, as well as the level of emotional dysregulation, level of app engagement and time of psychiatric admission during the follow-up period.DiscussionThis study is particularly relevant to young people given their widespread use of mobile technology, while there are currently no available smartphone app-based self-guided psychological strategies in Spanish that attempt to reduce suicidal behavior in adolescents who are assisted in the public health sector from low and middle-income countries in Latin America.Clinical trial registrationhttps://clinicaltrials.gov/, NCT05453370.
