Authors: Tufiño Guaicha Mayra Maribel , Cayambe Gordillo Johanna Karolina
Published: June 2023

El desarrollo de habilidades sociales permite en los estudiantes, de manera especial en los adolescentes mejorar su rendimiento en todos los ámbitos, sobre todo en el educativo donde comparten la mayoría de su tiempo, además donde se aplican diversas estrategias para medir su grado de responsabilidad con la academia que a corto plazo garantizará el cumplimiento de logros personales. Para ello se aplicó un cuestionario de selección múltiple que garantizó definir el alcance del rendimiento académico en los estudiantes dependiendo de dos variables, la una relacionada con el género y la otra el lugar de residencia. Esto permitió detectar que el ambiente de aprendizaje, el entorno familiar y social que comparten con sus compañeros de aula y allegados, influye en la presencia de habilidades sociales. Para lo cual el DECE debe propiciar una atención integral a las y los estudiantes, priorizando la inclusión de profesionales especialistas que impulsen el registro y documentación de los procedimientos y casos relevantes en el escenario educativo.

Aromaterapi ialah teknik yang dipakai untuk terapi aromatik, dan untuk melindungi serta menambah kesehatan fisik dan mental, termasuk dengan gangguan depresi dan stres. Lilin aromaterapi ialah salah satu aplikasi aromaterapi dengan cara dihirup (inhalasi) yaitu dengan menghirup uap aromatik yang didapatkan dari beberapa tetes minyak essensial pada tempat berisi air panas, dan salah satu minyak essensial yang telah digunakan untuk mengatasi kecemasan adalah jeruk bergamot (Citrus bergamia). Penelitian ini dilakukan untuk memformulasikan dan menguji sifat fisik pada lilin aromaterapi jeruk bergamot (Citrus bergamia). Soy wax dilelehkan diatas waterbath kemudian tambahkan minyak essensial jeruk bergamot (Citrus bergamia) sesuai dengan konsentrasi pada masing-masing formula. Lilin aromaterapi pada formula I menunjukkan konsentrasi minyak essensial terbaik dibandingkan dengan formula II dan formula III. Hal ini dikarenakan kadar minyak essensial tinggi akan berpengaruh pada sifat fisik lilin, yaitu titik lelehnya yang rendah dan waktu pembakaran lebih cepat sehingga membuat lilin cepat habis terbakar. Lilin aromaterapi pada formula III dengan  konsentrasi 6% minyak atsiri jeruk bergamot (Citrus bergamia) menunjukkan lilin aromaterapi yang paling banyak disukai responden.

Identification of genomic variants in regulatory elements associated with risk of suicide
Authors: Cardenas Natalia , Salazar Lorena
Published: June 2023

Suicide attempt is the consequence of a complex interaction between social traumatizing relations, environmental and genetics factors that might induce mood disorders. The genetic framework of schizophrenia, depression, bipolarity and anxiety disorders are very similar, with important genes involved in neurotransmission, circadian rhythm, serotonin pathways and more. We perform a non-coding scanning analysis using GWAS datasets of four previous suicidal attempts articles. 
P-value significant genetic variants ( ) were processed in a novel inferring software (http://inferno.lisanwanglab.org/index.php). We map up to 40 regulatory elements near to those genetic variants, that might be interfering in the expression of genes related to excitability of neurons, period and neuronal development, essential for a good mental health. This investigation allows the identification of new loci of interest related with suicidality and emphasizes the importance of including biological context enrichment to post GWAS analysis.
Perspective of Fetal Medicine in the era of prenatal genomics
Authors: Herrera Tania T.
Published: June 2023

In recent decades, prenatal medicine has progressively incorporated different diagnostic technologies that have been able to complement existing methods. Cytogenetic techniques such as karyotyping have been complemented with novel high-resolution molecular techniques, allowing the identification of genomic changes with single nucleotide resolution. Some of these techniques incorporated into the evaluation of prenatal cases are QF-PCR, comparative genomic hybridization (CGH array), different methods of massively parallel sequencing, among others.
Currently these molecular technologies for prenatal diagnosis are being implemented in our region since the last decade. Every implementation process brings with it advantages and challenges intrinsic to each technology, and the multidisciplinary team must clearly manage the indications for its use and the implications after the generation of results. In this paper we present some of the considerations by the American College of Genetic and Genomic Medicine and the International Society for Prenatal Diagnosis regarding the indications for these molecular tests and post-test counseling. This will allow the health personnel involved in these tests to implement them effectively, and to obtain a greater benefit for the patient.

Tourism Industry of Russia During the Crisis of 2022
Authors: Kovalenko V. V. , Davydova L. A.
Published: June 2023

Until March 2020, one of the developing sectors of the national economy of Russia was the tourism industry. The covid-19 pandemic, measures to protect the population from this virus, and Western sanctions have led Russia's tourism to a deep crisis. The purpose of the article is to substantiate the unfavorable conditions for the functioning of the tourism industry in Russia due to the COVID-19 pandemic and Western sanctions. The task of the work is to consider and show ways out of the difficult conditions created by Russian tourism, paying attention to the development of domestic tourism, support for outbound and inbound tourism. The prevailing unfavorable conditions gave a strong impetus to the development of domestic tourism. To do this, the Russian Government is taking certain measures to develop domestic tourism, such as cashback, the law on zeroing the VAT rate for hotels, which makes tourists' accommodation in them more affordable. The Government of the Russian Federation adopts the State Program "Tourism Development" and the National Project "Tourism and the Hospitality Industry.
ECO-INTEGRATIVE TERRITORIAL EVOCATION BY EMERGING NEW ARCHITECTURAL ECO-CLIMATIC STYLE
Authors: Toumi Labib , Kouzana Lamia
Published: June 2023

In this research work, the interest is directed towards the evocation of innovative neo-architectural dynamics in the Tunisian south-east territory, through an eco-integrative approach and the production of new eco-climatic architectural styles, based on the natural and cultural wealth of the Tunisian territory, authentic and revolutionary, yet marginalized and restricted, giving rise to reactions to the question that arises: “Is the situation of the vernacular heritage in the Tunisian south-east the direct result of a lack of vernacular heritage potential knowledge lack or of a modernist, restricted and reductive architectural production?” A multi-scale architectural study of rustic heritage has been developed, including a morpho-metric study, the analysis of hygrothermal diagrams produced in situ as well as the measurement of temperature and humidity inside the spaces. Neotroglodytic architecture, allows to highlight the intelligible integration of this new architectural mode in the mineral and arid desert landscape and to detect the aspect of an ecological and sustainable architecture, offering a humble, comfortable and welcoming intra-spatial atmosphere. Otherwise, in southeastern Tunisia, diagnostics have shown that rural villages, partially occupied and exploited in an anarchic manner, are subject to real dangers that threaten their survival in the Saharan territory, considered a difficult area. Direct consequences of an unsuitable development process, these historic works are perceived as static in the face of a dynamic social process, which has led to the gradual increase in their abandonment rates. Similarly, a disfigurement of the rustic landscape results from poor adaptation due to the standardized reproduction of architectural styles “in search of modernity”. The new troglodyte modes present a versatile and capacitive cultural potential. The manifestation of cultural and spatial wealth thus emerges, with the lasting potential of constituting a vector of cultural transition for the territorial development of southeastern Tunisia.
Blysmo compressi-Eriophoretum latifoliae ass. nova, a new association of the Caricion fuscae alliance from the Sharri Mountains
Authors: Berisha Naim , Ćušterevska Renata , Millaku Fadil , Matevski Vlado
Published: June 2023

The sedge-moss vegetation of the moderately to low calcium-rich slightly acidic fens of the Caricion fuscae alliance depends on a very specific combination of ecological and climatic conditions to thrive. Until recently, the classification of this vegetation group was complicated by its rarity on the southern edges of its range in Europe. As part of a larger database of phytocenological relevés carried out in Mt. Luboten, we came across an interesting group of 15 relevés on fen vegetation sites. We were curious to know if this plant community was a previously known association or if it might represent something new within this alliance. We compiled a separate dataset at JUICE that includes four plant communities from this alliance, along with our 15 original releves. The classification was based on modified TWINSPAN and beta-flexible clustering as a numerical classification method, with OPTIMCLASS determining the appropriate number of clusters. Five associations were clearly delineated, with the four associations taken from the literature sources clearly grouped individually and a new, fifth association appearing as separate, with completely unique characteristics. This new association: Blysmo compressi-Eriophoretum latifoliae occurs at elevations of ~ 1650 m a.s.l. on NE and NW slopes of the mountain. With this work we offer the description of a new high-mountain fen association. These associations may play an important syntaxonomic role as more Balkan data become available on this alliance. The sedge-moss and fen vegetation in the Balkans is particularly rare and characterised by a very diverse and specific vegetation, so it rightly deserves more attention from vegetation scientists and conservation authorities.

L’endométriose, une fabrique genrée de l’ignorance
Authors: Coville Marion
Published: June 2023

L’endométriose est une maladie chronique souvent qualifiée d’invisible. Celle-ci ne comporte pas de symptômes directement reconnaissables à la surface du corps et les lésions qu’elle entraîne résistent aux regards des professionnel-les de l’imagerie médicale. Des mécanismes d’invisibilisation et de disqualification façonnent également l’expérience des personnes atteintes d’endométriose et les confinent dans les marges de la production des savoirs. Les cadrages hégémoniques de l’endométriose ne reconnaissent alors que très partiellement leur vécu. Dans cette situation, comment produire le sens d’une expérience pour laquelle les mots sont disqualifiés ? Comment devient-on « malade de l’endométriose » et comment produit-on des connaissances à partir d’une expérience discréditée et invisibilisée ? Cet article propose une première piste de réponse en rendant compte d’une pratique auto-ethnographique, attentive au rôle de l’expérience corporelle dans la production du savoir.

Authors: Huang Yan , Zhang Yongfeng
Published: June 2023

Hospital lighting is an essential embodiment of hospital modernization. With the increasingly significant role of the medical environment in the medical process, both the lighting requirements of various treatments in the hospital and the response of patients to the lighting environment should be considered in the design. Avoid the discomfort and disgust of patients caused by improper lighting layout or illumination selection. To meet the physiological and psychological needs of patients and medical personnel, the light environment of medical buildings is no longer limited to meeting the requirements of illumination. Still, it focuses on strengthening its comfort and creating a harmonious and comfortable medical environment as well as possible. Starting from the lighting design of health treatments in medical centers and aiming at the light environment regulation requirements of medical buildings based on power carrier technology (PLCC), a lighting control system with easy implementation and simple operation is developed in this paper.
Lateral semicircular canal benign paroxysmal positional vertigo
Authors: Swain Santosh Kumar
Published: June 2023

Benign paroxysmal positional vertigo (BPPV) is one of the commonest etiologies for vertigo. The most common semicircular canal affected in the pathogenesis of BPPV is the posterior semicircular canal. However, lateral and anterior semicircular canals are also involved in BPPV, but their involvement in etiopathogenesis is still underrated. The pathophysiology for lateral canal BPPV (LC-BPPV) is attributed to otoconia present in the canal, either floating in the semicircular canal or adherent to the cupula. There are two types of LC-BPPV such as geotropic and apogeotropic/ageotropic. Till today, the role of the lateral semicircular canal (LSC) in BPPV is still the most debatable and grey area of the research niche. The geotropic type LC-BPPV is related to canalithiasis of freely mobile otoconia in the nonampullary arm of the LSC. Apogeotropic LC-BPPV is caused by canalithiasis in the ampullary arm or cupulolithiasis with otolithic debris located in the canal or utricular side of the LSC. The pathological side must be identified for successful treatment. The affected side is usually indicated by nystagmus intensity: The more intense positional nystagmus beats toward the affected ear. The identification of the affected ear is very crucial for the successful treatment of the LC-BPPV by using particle repositioning maneuvers. This review article discusses the epidemiology, etiopathology, clinical manifestations, diagnosis, and treatment of LC-BPPV in the pediatric age group.
Effect of Variable Melting Temperature on the Enthalpy Model for Runway Deicing
Authors: Maroufkhani Aida , Charpentier Claire , Morency Francois , Momen Gelareh
Published: June 2023

One of the most significant challenges for the aviation industry in the winter is the deicing operations on runways. As a result, deicer chemicals can pollute the environment if used in a large amount. A mathematical model could help optimize the use of deicer chemicals. Road deicing models exist to predict pavement temperature covered by snow/ice during deicing operations. However, the specificity of airport operations requires a model for the runway deicing to simulate the mass of ice melted with usage of deicing agents. Here we propose a model for runway deicing and validate it against experimental results. Our model considers temperature, diffusive flux, and time changes in a normal direction. It also calculates the mass and heat transfer in three regions (liquid, mushy, and solid). We used the enthalpy method to determine the temperature and the interface location at each time step. In the liquid and solid, the deicer concentration is obtained by Fick’s law and updated at each time step and location. The melting point temperature is variable due to the dilution of the deicer in the solution. Therefore, melting points are updated depending on the concentration at each location and time. The model uses the phases diagram for water and deicer agent mixture, considering eutectic point, for melting point calculation. The mesh dependency of the model is first investigated. To verify the model sensitivity, the paper proposes parametric studies for the heat transfer coefficient and the diffusion coefficients. Then, to validate the model, the Anti-Icing Materials International Laboratory (AMIL) in Chicoutimi conducted experimental tests on deicer agents for runways. Validation of the model is achieved for potassium acetate and potassium formate, two types of deicers.
Could Superhydrophobic Surfaces be a Realistic Solution for Running-Wet Areas?

Published: June 2023

Thermal ice protection systems (IPS) are used extensively in aeronautics. They are tailored according to the aircraft characteristics or flight envelope and can be used in different modes, anti-icing to avoid ice accretion or de-icing to remove the ice once accreted. A relevant issue by this application is the runback icing, caused by the downstream flow of melted or running water to unprotected areas, where activation is not possible in terms of energy consumption. Passive systems are being explored to complement or replace active systems, although, up to now, solutions have not been reported with the required performance for real-life applications.

One of the most commonly reported anti-icing strategy relays on superhydrophobicity, i.e., it is based on the water roll-off capacity of Cassie-Baxter superhydrophobic surfaces (CB-SHP). Precisely, running wet phenomena, where liquid water is flowing on the surface, could be an appropiate application field for this type of materials. Herein, we have explored the behavior and limitations of a stable, newly developed, CB-SHP material to protect a runback section under icing conditions (temperature, air speed, liquid water content, droplet size distribution, and angle of attack) closer to those encountered in a wing airfoil.Two icing mechanisms, running-wet and direct impingement of supercooled microdroplets, have been evaluated for short (2 minutes) and long (10 minutes) period tests. It is found that the tested SHP material improved the performance of reference polyurethane (PU) paints, avoiding any ice accretion at low air speeds and low angles of attack.
Effect of Surface Modification on the Hybrid Ice Protection Systems Performances

Published: June 2023

The formation of ice can be very detrimental to flight safety, since the ice accumulated on the surfaces of the aircraft can alter both the aerodynamics and the weight, leading in some cases to catastrophic lift reductions. Traditional active Ice Protection Systems (IPS) require high energy to work, add on weight to the aircraft and complexity to the manufacturing. On the other hand, the use of passive IPS, such as superhydrophobic/icephobic coatings, cannot be successful in harsh environmental conditions or for prolongated icing expositions. So, a valuable solution could be the combination of active and passive IPS with the aim to combine the advantage of both of them and mitigate their drawbacks. In this context, the present work proposes two innovative Hybrid IPS, based on an ultrasound piezoelectric system and on a thermoelectric system manufactured using carbon fibers as heater elements, both combined with a superhydrophobic coating with the aim to study the effect of the surface wettability on their power consumption. Preliminary simulations and design calculations give evidence that the reduced surface wettability achieved through the application of a superhydrophobic coating can be highly helpful in the reduction of the power supply required from the two active IPS. The energy saving has been estimated as ranging from 96.5% at 250V to 91.2% at 1000V for the hybrid ultrasound piezoelectric-superhydrophobic coating system, and up to 53% depending to the water droplet volume and the surface temperature, for the hybrid thermoelectric-superhydrophobic coating system.
Durable Icephobic and Erosion Resistant Coatings Based on Quasicrystals
Authors: Yang Qimeng , Dolatabadi Ali , Golovin Kevin
Published: June 2023

Quasicrystalline (QC) coatings were evaluated as leading-edge protection materials for rotor craft blades. The QC coatings were deposited using high velocity oxy-fuel thermal spray and predominantly Al-based compositions. Ice adhesion, interfacial toughness with ice, wettability, topography, and durability were assessed. QC-coated sand-blasted carbon steel exhibited better performance in terms of low surface roughness (Sa ~ 0.2 μm), liquid repellency (water contact angles: θadv ~85°, θrec ~23°), and better substrate adhesion compared to stainless steel substrates. To enhance coating performance, QC-coated sand-blasted carbon steel was further exposed to grinding and polishing, followed by measuring surface roughness, wettability, and ice adhesion strength. This reduced the surface roughness of the QC coating by 75%, resulting in lower ice adhesion strengths similar to previously reported values (~400 kPa). The durability of polished QC coating was evaluated using sand and rain erosion. The sand erosion test was conducted per ASTM D823. The thickness of the QC coating remained unchanged post-erosion, indicating the QC coating is quite resistant to abrasion from sand. Rain erosion tests were conducted following the Icephobic Comparative Jet Pulsating Rain Erosion test (ICPjet) at the Anti-icing Materials International Laboratory, Quebec. The coating remained intact even after 190,000 impacts demonstrating extreme durability against rain erosion, and the coating outperformed current erosion-resistant aircraft paint (SAE AMS-C-83231A). Overall, the extreme erosion resistance of the easy-to-spray coating, combined with its de-icing properties and ability to be repaired using standard polishing techniques, makes the developed quasicrystalline coatings extremely promising for the protection of rotor-craft blades and other aircraft components.
Multi-Physics Simulations of Ice Shedding from Wind Turbines
Authors: Rausa Andrea , Caccia Francesco , Guardone Alberto
Published: June 2023

Wind turbines in cold climates are likely to suffer from icing events, deteriorating the aerodynamic performances of the blades and decreasing their power output. Continuous ice accretion causes an increase in the ice mass and, consequently, in the centrifugal force to which the ice shape is subjected. This can result in the shedding of chunks of ice, which can jeopardize the aeroelastic properties of the blade and, most importantly, the safety of the surrounding people and of the wind turbine structure itself. In this work, ice shedding analysis is performed on a quasi-3D, multi-step ice geometry accreted on the NREL 5MW reference wind turbine. A preliminary investigation is performed by including the presence of an ice protection system to decrease the adhesion surface of the ice on the blade. A reference test case with a simple geometry is used as verification for the correct implementation of the procedure. The procedure was shown to be robust and will be used in the future within an optimization framework of a de-icing system.
Design and Testing of an Indirect Ice Detection Methodology
Authors: Deiler Christoph , Sachs Falk
Published: June 2023

Distinct atmospheric conditions containing supercooled large droplets (SLD) have been identified as cause of severe accidents over the last decades as existing countermeasures even on modern aircraft are not necessarily effective against SLD-ice. Therefore, the detection of such conditions is crucial and required for future transport aircraft certification. However, the reliable detection is a very challenging task. The EU funded Horizon 2020 project SENS4ICE targets this gap with new ice detection approaches and innovative sensor hybridization. The indirect ice detection methodology presented herein is key to this approach and based on the changes of airplane flight characteristics under icing influence. A performance-based approach is chosen detecting an abnormal flight performance throughout the normal operational flight. It is solely based on a priori knowledge about the aircraft characteristic and the current measurable flight state. This paper provides a proof of concept for the performance-based ice detection: starting with the evaluation of operational flight data for different example aircraft the expectable flight performance variation within a fleet of same type is shown which must be smaller than the expected icing influence for reliable detection. Next, the implementation of the indirect ice detection system (IIDS) algorithms in SENS4ICE is detailed with certain regard to the flight test implementation for final validation. Finally, the initial methodology verification and validation results are presented and discussed.

Authors: Pham Cuong , Caso Taymy J. , Cullen Michael J. , Seltzer Benjamin K. , Mustapha Taj , Utrzan Damir S. , Rider G. Nic
Published: June 2023

Background

Underrepresented in medicine (UIM) interns have unique lived experiences that affect their paths to medicine, and more information is needed for medical residency and fellowship programs to better support them.

Objective

We describe self-reported differences between UIM and White physician interns in key demographic areas, including household income growing up, physician mentorship, and adverse childhood experiences (ACEs).

Methods

Between 2019 and 2021, we administered a diversity survey to incoming medical interns at the University of Minnesota-Twin Cities. Response rates across the 3 years were 51.2% (167 of 326), 93.9% (310 of 330), and 98.9% (354 of 358), respectively. We conducted analyses to compare UIM and White groups across demographic variables of interest.

Results

A total of 831 of 1014 interns (81.9%) completed the survey. Relative to White interns, UIM interns had lower household incomes growing up, lower rates of mentorship, and higher rates of experiencing 4 or more ACEs. The odds of experiencing the cumulative burden of having a childhood household income of $29,999 or less, no physician mentor, and 4 or more ACEs was approximately 10 times higher among UIM (6.41%) than White (0.66%) interns (OR=10.38, 95% CI 1.97-54.55).

Conclusions

Childhood household income, prior mentorship experiences, and number of ACEs differed between UIM and White interns.

DARE best practices were developed from available anti-racism and equity educational materials. Volunteer trainees and faculty in the department of medicine of a large urban academic medical center were recruited and underwent an hourlong training to utilize DARE best practices to coach faculty on improving the anti-racist and equity content of educational conferences. DARE coaches then met with faculty to review the planned 2021-2022 academic year (AY) lectures and facilitate alignment with DARE best practices. A rubric was created from DARE practices and utilized to compare pre-intervention (AY21) and post-intervention (AY22) conferences.

Results

Using the DARE best practices while coaching increased the anti-racism and equity content from AY21 to AY22 (total rubric score mean [SD] 0.16 [1.19] to 1.38 [1.39]; P=.001; possible scores -4 to +5), with 75% (21 of 28) of AY22 conferences showing improvement. This included increased diversity of photographs, discussion of the racial or ethnic makeup of research study participants, appropriate use of race in case vignettes, and discussion of the impact of racism or bias on health disparities.

Conclusions

Training coaches to implement DARE best practices improved the anti-racism and equity content of existing noontime internal medicine residency educational conferences.

Published: June 2023

Background

The format for residents to present hospitalized patients to teaching faculty is well defined; however, guidance for presenting in clinic is not uniform.

Objective

We report the development, implementation, and evaluation of a new standardized format for presenting in clinic: the Problem-Based Presentation (PBP).

Methods

After a needs assessment, we implemented the format at the teaching clinics of our internal medicine residency program. We surveyed participants on innovation outcomes, feasibility, and acceptability (pre-post design; 2019-2020; 5-point scale). Residents' primary outcomes were confidence in presentation content and presentation order, presentation efficiency, and presentation organization. Faculty were asked about the primary outcomes of resident presentation efficiency, presentation organization, and satisfaction with resident presentations.

Results

Participants were 111 residents and 22 faculty (pre-intervention) and 110 residents and 20 faculty (post-intervention). Residents' confidence in knowing what the attending physician wants to hear in an outpatient presentation, confidence in what order to present the information, and how organized they felt when presenting in clinic improved (all P<.001; absolute increase of the top 2 ratings of 25%, 28%, and 31%, respectively). Residents' perceived education in their outpatient clinic also improved (P=.002; absolute increase of the top 2 ratings of 19%). Faculty were more satisfied with the structured presentations (P=.008; absolute increase of the top 2 ratings of 27%).

Conclusions

Implementation of a new format for presenting in clinic was associated with increased resident confidence in presentation content, order of items, overall organization, and a perceived increase in the frequency of teaching points reviewed by attending physicians.

Background

Early identification of COVID-19 symptoms and burnout among residents is essential for proper management. Digital assistants might help in the large-scale screening of residents.

Objective

To assess the implementation of a chatbot for tele-screening emotional exhaustion and COVID-19 among residents at a hospital in Brazil.

Methods

From August to October 2020, a chatbot sent participants' phones a daily question about COVID-19 symptoms and a weekly question about emotional exhaustion. After 8 weeks, the residents answered the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). The primary outcome was the reliability of the chatbot in identifying suspect cases of COVID-19 and burnout.

Results

Among the 489 eligible residents, 174 (35.6%) agreed to participate. The chatbot identified 61 positive responses for COVID-19 symptoms, and clinical suspicion was confirmed in 9 residents. User error in the first weeks was the leading cause (57.7%, 30 of 52) of nonconfirmed suspicion. The chatbot failed to identify 3 participants with COVID-19 due to nonresponse. Twelve of 118 (10.2%) participants who answered the MBI-HSS were characterized as having burnout by the MBI-HHS. Two of them were identified as at risk by the chatbot and 8 never answered the emotional exhaustion screening question. Conversely, among the 19 participants identified as at risk for emotional exhaustion by the chatbot, 2 (10.5%) were classified with burnout, and 5 (26.3%) as overextended based on MBI-HHS scores.

Conclusions

The chatbot was able to identify residents suspected of having COVID-19 and those at risk for burnout. Nonresponse was the leading cause of failure in identifying those at risk.

Published: June 2023

Substance use disorder is a major contributor to disability adjusted life year. Globally and especially in Africa there is high treatment gap for substance use disorders (SUDs) and lack of training in addiction psychiatry. This commentary discusses challenges to SUD treatment and training in Africa and offers suggestions to advance the field. Sociopolitical and health system factors limit the availability of treatment and training of healthcare providers for addiction in Africa. It is essential that governments in Africa prioritise investment in addiction treatment and training to reduce the morbidity and mortality associated with lack of treatment.
Substance use under a restrictive and prohibitive policy regime in secondary schools in Uganda: The convergence of motives, contexts and student characteristics

Drug use among young people is increasing in Africa. To prevent drug use, it is essential to understand the motivations, environments, and characteristics of users. Although there are established risk factors for drug use, little is known about the reasons why adolescents and young people take drugs. This study investigated the reasons given by a sample of secondary school pupils for using drugs and other substances, specifically, how adolescents circumvent the restrictive and prohibitive policy regime and rationalize and account for drug use. This study used a cross-sectional mixed-methods design. For quantitative data, descriptive and regression analyses were run, and for qualitative data, thematic analysis was used. About 13 per cent (n=41) met criteria for moderate to severe drug use. Coping (Mean = 4.13, SD 0.89), social (Mean = 3.71, SD 0.97), and enhancement (Mean = 3.09, SD 0.92) motives were highly endorsed as motives for drug use. The extent to which motives predicted drug use ranged from β = 0.55 (95% CI: 0.39, 0.72) for coping to β = 0.18 (95% CI: 0.08, 0.28) for expansion motives. Students employed ingenious and frequently risky ways to circumvent the rigorous and prohibitive regulatory regimes governing drug use in schools. Academic stress, limited recreational activities, poor stress management, peer influence, poor adult supervision and dysfunctional family backgrounds, all interrelate in complex ways with motives, contexts, and student characteristics to create a conducive environment for the rationalisation, medicalisation, and veneration of drug use. Further research on contexts, motives and characteristics of adolescents that shape drug use is needed.
