Des « boues rouges » à la Bauxaline
Authors: Le Berre Sylvain , Goujon Valentin , Banos Vincent 
Published: December 2023

Utilisée pour la fabrication de l’alumine et de l’aluminium, la bauxite est une des ressources naturelles cruciales de nos sociétés industrielles contemporaines. Sa transformation génère cependant des restes chargés en métaux lourds et matières radioactives : les « boues rouges ». À l’usine de Gardanne, après plusieurs tentatives infructueuses depuis la fin du XIXe siècle pour requalifier et réutiliser ces boues en une ressource nouvelle, le régime de gestion de ces déchets consistera tout au long du XXe siècle en un entreposage à terre et une évacuation en mer. Devant répondre à une contestation sociale importante et à des contraintes réglementaires plus fortes sur la préservation de l’environnement et la gestion des déchets, l’exploitant industriel relance au tournant des années 1990 les expérimentations de valorisation des boues rouges. Cette démarche de Recherche & Développement vise, tout d’abord, à démontrer l’innocuité environnementale des résidus une fois requalifiés et, ensuite, à favoriser leur redéfinition marchande afin de les « évacuer » sous la forme d’un nouveau produit commercialisable : la Bauxaline®. Mais dans la lignée des difficultés rencontrées dès la fin du 19ème siècle, toutes les pistes vont échouer. Ces échecs successifs témoignent de l’incapacité de l’ingénierie industrielle à « valoriser » ces résidus mais aussi à maîtriser la matérialité même des boues rouges. L’analyse de quatre types d’expérimentations en mer, au sol et en sous-sol, permet de voir combien l’ingénierie industrielle se fait à l’épreuve des fragilités de la matérialité, qui résultent de l’entremêlement de l’agentivité minérale et résiduelle, et des agencements technomarchands.
The Relationship Between Rest Breaks and Professional Burnout Among Nurses
Authors: Stutting Halle L. 
Published: December 2023

Background
Professional burnout is a well-studied phenomenon marked by feelings of depersonalization, emotional exhaustion, and decreased accomplishment. Affecting nearly half of all nurses, burnout presents a threat to health outcomes of the nurse, patient, organization, and society. Despite a growing literature on professional burnout, specific interventions that address key contributing factors have not been well described.

Objective
The primary aim of this integrative literature review was to evaluate the relationship between rest breaks and professional burnout among registered nurses.

Methods
A literature search was performed in the APA (American Psychological Association) PsycInfo, CINAHL (Cumulative Index of Nursing and Allied Health Literature), Cochrane Library, Embase, and PubMed databases using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses as a reporting guideline.

Results
Five articles were selected for final synthesis; 1 was of “high” quality and 4 were of “good” quality. The literature showed that rest breaks were protective against professional burnout among registered nurses, especially when integrated with nursing management support, staffing support, and complementary strategies. Several threats to validity were identified as limitations among the articles selected for final synthesis.

Conclusions
Rest breaks are effective in decreasing professional burnout among registered nurses, especially when combined with management support, staffing support, and complementary strategies. Future research should focus on a deeper evaluation of staffing support models, as well as identifying how nursing leaders can integrate complementary strategies across health care settings to reduce burnout.
Use of a Digital Air Leak Detection Device to Decrease Chest Tube Duration
Authors: Patel Carla , Ruppert Susan D. , Cao Hue , Fraser Cheryl , Laury TaCharra , Vaporciyan Ara 
Published: December 2023

Background
The aim of this evidence-based practice project was to determine if a digital air leak detection device could speed the identification of chest tube air leak cessation in patients after pulmonary lobectomy. Staff members assessing air leaks have varying levels of expertise, and the digital device is a limited resource in the study institution. A chest tube management algorithm is necessary to standardize care and determine which patients are most likely to benefit.

Implementation
Twenty-five consecutive patients who underwent pulmonary lobectomy during the study period and continued to have a chest tube air leak on postoperative day 3 were monitored with digital air leak detection devices. The Mann-Whitney U test was used to compare chest tube duration and hospital length of stay between patients with digital devices and 259 patients who had traditional analog air leak detection devices (historical data from the departmental database over the previous 2 years).

Evaluation
Median chest tube duration and hospital stay were 1 day less in patients with digital devices than in those with traditional analog devices (P = .01 and P = .004, respectively), with a cost savings of $2659 per hospital day. Reductions in chest tube duration and length of stay aided in the development of a chest tube management algorithm.

Conclusions
Critical care nurses are valued team members who treat patients after lung resections. Digital air leak detection devices can help them assess air leaks more accurately, benefiting the patients in their care.
Interspecific differences in the questing behaviour of Dermacentor andersoni and Dermacentor variabilis (Acari: Ixodidae) larvae
Authors: Diyes Chulantha P. , Dergousoff Shaun J. , Chilton Neil B. 
Published: December 2023

Abstract
Dermacentor variabilis and Dermacentor andersoni (Acari: Ixodidae) parasitise the same range of hosts in western Canada and have largely allopatric ranges except for a zone of sympatry in southern Saskatchewan, where these species experience the same environmental conditions. We report herein the discovery of differences in the behaviour of D. variabilis and D. andersoni larvae after they emerge from eggs. A behavioural diapause observed in D. variabilis larvae was not detected in D. andersoni larvae that were exposed to the same environmental conditions. As unfed D. variabilis larvae can successfully overwinter, their behavioural diapause represents an adaptive strategy to synchronise their questing activity and life cycle stage to maximise the chance of larvae encountering a suitable rodent host at the onset of spring. Such strategy will be of a significant benefit for colonising individuals at the northern edge of the distributional range of D. variabilis.

Conturbadas Memórias: narrativas da nação brava
Authors: Miguel Marcelo  Calderari 
Published: December 2023

Os três poemas apresentam diferentes momentos históricos e eventos importantes na história do Brasil. Eles retratam momentos de agitação política, lutas pela liberdade e confrontos regionais.
No primeiro poema, intitulado "I Constituinte e Chalaça, Noite da Agonia", é destacada a tumultuada sessão da Assembleia Constituinte brasileira, onde deputados debatiam a elaboração de uma constituição. O conflito entre Antônio Carlos de Andrada e o imperador D. Pedro I é abordado, mostrando a tensão e o embate de ideias na busca pela liberdade. A aprovação da proposta constitucional traz consigo a agonia, pois o ministro do Império impõe restrições à imprensa e demissões, colocando a liberdade em perigo.
O segundo poema, intitulado "II Onde repousam Heróis, épica é a batalha", rememora a Batalha do Jenipapo, um marco da luta pela independência do Brasil. O poema destaca a importância do cemitério do Batalhão e do monumento do Jenipapo como símbolos venerados e honrados da história do país. A bravura e coragem dos combatentes são exaltadas, mesmo diante da derrota, e seu legado serve como exemplo inspirador para as gerações futuras.
O terceiro poema, intitulado "III Revoltas no Pampa, Maragatos e Chimangos", retrata a Revolução de 1923 no Rio Grande do Sul. O conflito entre os Maragatos, defensores de Assis Brasil, e os Chimangos, apoiadores de Borges de Medeiros, é destacado. A crise na pecuária e a fraude na reeleição são apontadas como desencadeantes da revolta. O poema ressalta a violência e a censura à imprensa durante o período, além de enfatizar a união dos revolucionários em colunas e o impacto do conflito na história do Rio Grande do Sul.
Em suma, os três poemas despertam reflexões sobre a importância desses eventos e seu legado na construção entre memória, identidade, patrimônio e o destino do país e da brava gente brasileira.

The burden of cardiovascular disease in South Asia: the need for effective treatment
Authors: Immad Muhammad Usman  
Published: December 2023

Dear Ma'am,
Cardiovascular disease (CVD) is rapidly becoming the leading cause of death worldwide (1). According to global health projections, it will remain the number one cause of death in 2030. The Asian region has been shown to have a higher cardiovascular disease burden than Western countries, and most of this burden is borne by economically disadvantaged people mainly located in South Asian regions such as Pakistan. (1). A large-scale survey conducted in 53 cities in Punjab, Pakistan, found that 17.5% of the population suffered from cardiovascular disease (2).
Mechanical thrombectomy is a minimally-invasive procedure where a specialized interventional radiologist utilizes specific equipment to remove a blood clot from an artery in a patient's body. This procedure treats arterial blockages caused by blood clots such as Deep Vein Thrombosis (DVT), Ischemic Stroke, etc (3).
MegaVac, a part of mechanical thrombectomy, is the newest technique for the removal of blood clots from arteries. It is an invasive procedure that ensures the complete removal of clots from the occluded artery. The biggest advantage of this technique over typical clot removal is that it prevents embolus formation, which can occlude smaller arteries.
The MegaVac Thrombectomy System is an intravascular mechanical thrombectomy and aspiration device with a single use that includes a thrombowire with an embolectomy component. A distal silicone-coated nitinol braid used in the SafeSealTM technology of the MegaVac Catheter swells to momentarily obstruct antegrade blood flow. The braid is expanded by the inner and outer coaxial shafts of the catheter body, briefly occluding the channel and enabling aspiration. SafeSeal funnel is activated by the assembly of the proximal handle. A nitinol embolectomy component that is part of the thrombowire can be used to draw material in the direction of the MegaVac catheter when it is inflated by the proximal actuation handle (4).
Thrombectomy is a common and effective procedure for clot removal but in Pakistan thrombectomy is not as common compared to developed countries, primarily due to two reasons. First, Mechanical thrombectomy is exclusively available in four hospitals nationwide, with only one public hospital in Lahore providing this procedure (5). Second, it is an expensive procedure that ranges from 1700$ to 5000$ depending on the severity of the patient and the complexity of the procedure. Health Departments of Pakistan should provide this facility in more public hospitals so it becomes accessible to more people.
Ophthalmology: a dwindling specialty in Pakistan
Authors: Tariq Moeez , Maanak Asif  , Ghazala Masood Farrukh  
Published: December 2023

Madam Editor,
Ophthalmology is a branch of medical science that deals with diagnosing and treating eye disorders. It comprises both the medicinal and surgical aspects of eye care. Medical students choose a specific field of their interest as their future speciality. It is the dream of every medical student to go far in his or her field of study and to make good progress. Some students choose Medicine while others opt Surgery. Even in surgery, some students choose General surgery, while others choose other surgical interests, such as Cardiac surgery, Gynaecology, Neurosurgery, etc. The same thing happens in the field of medicine i.e., they want to become Internists, Pediatricians, Dermatologists, Neurologists and Cardiologists. But the tendency of students to opt Ophthalmology is observed to be less in Pakistan (1).
According to Aslam M, et al. (2011), only 1.7% of medical students in the .public sector and 3.3% of medical students in private sector medical colleges preferred Ophthalmology.(2). Another study by Hamid S et al., in 2019 conducted on the fourth and final year medical students, and house officers showed that only 3.8% of the participants were interested in Ophthalmology as a future subject of speciality, with a male to female ratio being 1:3 ,which is alarming as well (3). The main factors influencing medical students not to choose Ophthalmology include, fewer chances of residency, prolonged duration of residency, and limited opportunities in the private sector (4). Besides this, students often perceived Ophthalmology as a ‘dry subject’ by students. The basics of the eye i.e., anatomy, histology, embryology, and physiology are also extensive and difficult to be retained for a prolonged period. Poor retention of concepts can also affect the specialty preference concerning Ophthalmology among medical students.
Though there are many benefits of choosing the field as a speciality, some being high income, less working hours and no duties in the night (4). Almost all cases in Ophthalmology are treated in daycare settings and the surgeries are also mainly elective procedures as there are fewer emergency calls. Moreover, sub-specialties are offered including Paediatric Ophthalmology, Orbit and Oculoplastics, and Vitreoretinal Ophthalmology (5). According to the International Council of Ophthalmology, there are 1860 ophthalmologists in Pakistan with 11 ophthalmologists per million of the population (1). There is a dire need for ophthalmologists in the country.

Validity of SenseWear Armband in assessing the energy expenditure at different exercise intensities during menstrual cycle
Authors: Yılmaz Fatma , Goren Kose Mehmet , Kin İsler Ayse , Hazır Tahir 
Published: December 2023

Objective: The purpose of this study was to determine the validity of the SenseWear Armband (SWA) in assessing the energy expenditure at different exercise intensities during midfollicular and luteal phases of the menstrual cycle.
Material and Methods: Twenty volunteer women athletes (age: 20.6±1.6 yrs, height: 168.3±7.3 cm; menstrual cycle: 28.8±2.1 days) with regular menstrual cycle participated in the study. Participants performed treadmill running exercise for 10 min at 35% and 75% of their VO2max in their midfollicular (days 7-9) and luteal phases (days 21-23). Phases of the menstrual cycle were confirmed by hormone analysis. Energy expenditure during the running exercise was assessed simultaneously by the indirect calorimetric method, and the SWA. Multi-way ANOVA was used for the effect of method (2) x phase (2) x intensity (2) on energy expenditure. In addition, the Pearson correlation coefficient was determined between the variables.
Results: Estradiol and progesterone levels measured in the midfollicular phase were significantly higher than in luteal phase (p<0.05). Energy expenditure at 75% intensity was significantly higher than energy expenditure at 35% intensity (p<0.05). No significant method (p>0.05) and phase (p>0.05) effect was found in energy expenditure. There was no significant method x phase, phase x intensity, and method x phase x intensity interaction (p>0.05), however method x intensity interaction was significant (p<0.05). At the midfollicular phase the correlations between energy levels from indirect calorimetric and SWA methods were not significant (for 35%, r=0.382; for 75%, r=0.147; p>0.05). In contrast, significant correlation was found between energy levels from the indirect calorimetric, and the SWA methods at the luteal phase (for 35%, r=0.495; for 75%, r=0.748; p<0.05).
Conclusions: The results of the present study indicated that energy expenditures at different menstrual phases were similar and that SWA was a valid method in assessing energy expenditure at different exercise intensities during the menstrual cycle.
Rambling and trembling trajectories in the analysis of postural sway prior to the self-paced and reaction time tasks
Authors: Celik Huseyin , Yilmaz Ugur , Arpinar Avsar Pinar 
Published: December 2023

Objective: Previous studies suggested that center of pressure (COP) shifts occur before an expected perturbation in the form of early and anticipatory postural adjustments which operate in a short time scale. However, the effect of such perturbations on pre-existing postural set on a longer time scale remained uncovered. The purpose of this study was to investigate whether rambling and trembling components of the COP trajectories depend on postural task or phase of trial before a self-initiated perturbation.
Materials and Methods: Twenty-four young healthy participants took part in the study. Subjects performed three postural tasks, namely, (i) quiet stance task: 60 seconds quiet stance, (ii) self-paced task: maximal vertical jump from quiet stance under the self-paced time condition, and (iii) reaction-time task: maximal vertical jump from quiet stance under the reaction-time condition. Postural sway features were examined in two phases, the first and last 20 seconds of the trials.
Results: The features of rambling and trembling components of the COP trajectories were affected by postural task or phase of trial. The ellipse area of the COP and rambling trajectories were significantly different among postural tasks. The median frequency was significantly different between the phases of trials for the COP and rambling trajectories.
Conclusion: This study indicated task-specific changes in postural sway features. Rambling and trembling trajectories, which would reflect two underlying human postural control mechanisms as maintaining the body's equilibrium with respect to a moving reference point and oscillating around the moving reference point respectively, were affected differently before a whole-body maximum-effort self-initiated perturbation.
