Cribado de parto prematuro con progesterona salival
Authors: Haye M. M. Teresa , Garrido P. Maritza , Aleuanlli A. M. Cristina , Parra-Cordero Mauro
Published: June 2023

Preterm birth is the most frequent cause of perinatal morbidity and mortality, especially before 34 weeks. Current screening methods include medical history of preterm delivery and ultrasound assessment of cervix length during the second trimester of pregnancy, which give a detection rate of approximately 65% with a false positive rate of 10%. Vaginal progesterone therapy has proved to reduce the risk of early preterm delivery by 50% in patient under risk. This might suggest that preterm pregnancies have lower levels of progesterone compared to term pregnancies. Although, the prediction of prematurity using biomarkers, including plasma progesterone, has been researched for several years, none of them have proved to be associated with preterm delivery. However, measuring salivary progesterone has already been suggested to be a potential biomarker associated with prematurity in pregnancies at high risk of preterm delivery. Saliva is a fluid that reflects only the free fraction of the biologically active steroidal hormone, and thus is more representative measure than the total plasma progesterone, which is the one usually measured in laboratories. For these reasons, the aim of our study is to evaluate whether the assessment of salivary progesterone can be used as a screening test for prediction of preterm delivery less than 34 weeks in pregnant women who attended at our Fetal Medicine Unit at 11-14 and 20-25 weeks of gestation.

Published: June 2023

The beginning of the implementation at the institutional level of Law 21.030, relating to the decriminalization of pregnancy for three reasons, has generated concerns, practical difficulties and changes in the dynamics of work teams in hospitals that have had to implementar. These difficulties refer to areas as varied as diagnosis, confirmation of the causes, to the opposition of different professionals in their participation in the process. In this first communication we will summarize the last of the problems arising from the new protocol issued by the Ministry of Health, regarding the Institutional Awareness Objection in Hospitals that, like the HCUCH, have an agreement with FONASA.

Authors: Calderón H. Perla , Águila B. Vivian , Manfredi S. Jocelyn
Published: June 2023

INTRODUCTION: Sweet (SS) syndrome is a neutrophilic dermatosis, characterized by a rapid onset of painful erythematous-purplish papules, nodules or plaques, accompanied by fever and associated with a dermal neutrophil infiltrate. CASE REPORT: Male, 69 years old, with a history of mild plaque psoriasis, arterial hypertension, gastroesophageal reflux and chronic sinusitis. He consulted for a 24-hour period characterized by headache and pain in the scalp. The examination highlights fever (38.5°), with slight erythema, sensitivity to palpation and some psoriasis plaques on the scalp. 48 hours later, it presents extensive painful erythematouspurplish plaques, present only on his right face and scalp. Biopsy was informed as Sweet Syndrome. He completed 14 days on prednisone, with excellent clinical evolution. DISCUSSION Sweet syndrome is classified into three categories: classic or idiopathic (most common), drug induced and associated with malignancy. In addition, other conditions have been described which may be related to: infections, autoimmune diseases, pregnancy. The management is focused on investigating an underlying cause and the use of corticosteroids, as a first line therapy. We report a case of idiopathic Sweet syndrome with atypical presentation, which was initially interpreted as facial cellulitis, with a rapid response to systemic corticosteroids.

Perniosis idiopática: reporte de un caso y revisión de la literatura
Authors: Valenzuela A. Fernando , Carvajal A. Daniela , Minuzzi Giacomo , Gárate G. Lorena
Published: June 2023

Pernio (chilblains) is an inflammatory condition classically characterized by localized erythema and swelling of acral sites upon exposure to cool and damp conditions. It is reported a case of a 59-year-old otherwise healthy woman with acute primary perniosis. She had a 3-day history of lesions on the toes brought on by cold, damp weather. On initial presentation, a biopsy sample was taken of a hallux lesion, and the patient was given a trial course of oral pentoxifylline, topical corticoid and nifedipine therapy. Follow-up at 2 weeks showed complete relief of symptoms and the biopsy results confirmed the diagnosis. Pentoxifylline therapy has

been shown to be effective and should be considered the standard of care in the treatment of perniosis along with conservative environmental measures.The etiology and pathogenesis of perniosis are reviewed and discussed, as well as differential diagnoses and treatment options.

The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative commenced during a World Health Organization (WHO) workshop in 1999. The initial goals were (i) to propose a new allergic rhinitis classification, (ii) to promote the concept of multi-morbidity in asthma and rhinitis and (iii) to develop guidelines with all stakeholders for global use in all countries and populations. ARIA - disseminated and implemented in over 70 countries globally - is now focusing on the implementation of emerging technologies for individualized and predictive medicine. MASK (MACVIA (Contre les MAladies Chroniques pour un VIeillissement Actif)-ARIA Sentinel NetworK)

uses mobile technology to develop care pathways in order to enable the management of rhinitis and asthma by a multi-disciplinary group or by patients themselves. An App (Android and iOS) is available in 20 countries and 15 languages. It uses a visual analogue scale to assess symptom control and work productivity as well as a clinical decision support system. It is associated with an

inter-operable tablet for physicians and other health care professionals. The scaling up strategy uses the recommendations of the European Innovation Partnership on Active and Healthy Ageing.

Published: June 2023

Introduction: Grover’s disease (GD) or transient acantholytic dermatosis, is a papulovesicular pruritic disease of unknown etiology. It´s most important histopathological finding is the presence of focal acantholysis. The incidence has not been firmly established. Case report: We report two cases of papulovesicular rashes, the first one in a 79 year old man with good response to second line treatment and the second one, in a 30 year old woman. Both with different suspected triggering factors. Comment: GD predominates in white men with an average age of presentation of 61. Clinically, it presents as erythematous papules, crusted-papule and is usually pruritic. The etiopathology is still unknown, but it is associated with triggers such as: ultraviolet radiation (UVR), ionizing radiation, heat, sweat, friction and chemotherapy. Acantholysis is the classic histological finding. Management includes general measures, topical corticosteroids, calcineurin inhibitors, tretinoin, calcipotriene and antihistamines. In refractory cases, second-line treatment is used: oral isotretinoin, systemic corticosteroids and phototherapy. Paradoxically, phototherapy can also trigger GD. Conclusions: Due to the low prevalence of GD in Chile, 2 new cases are provided to the literature. In both cases, the diagnostic presumption was based on an exhaustive clinical history, confirmed by histopathological findings.
Síndrome coronario agudo sin supradesnivel ST. Diagnóstico y tratamiento inicial
Authors: Ugalde P. Héctor
Published: June 2023

Coronary heart disease can manifest as stable or unstable forms, being these variations

differentiated mainly by the underlying pathophysiological cause, their clinical presentation

and the risk associated to each of these clinical presentations. In the unstable form, nowadays

known as acute coronary syndrome, recommendations over its characterization and particularly

its management are periodically updated in published international guidelines about this topic.

Their epidemiological relevance makes important that these aspects should be known by

anyone that sees patients in their practices, motivating this review in which we will summarize

aspects of the clinical presentation, initial studies and management of the acute coronary

syndrome without ST segment elevation emphasizing novelties from the last few years.
Perfil de presión uretral
Authors: Valdevenito S. Juan Pablo
Published: June 2023

The “urethral pressure profile” is a graph indicating the intraluminal pressure along the length

of the urethra and the “urethral closure pressure profile” is given by the substraction of

intravesical pressure (pves) from urethral pressure (pura). Both aim to represent the ability

of the urethra to prevent involuntary leakage of urine on efforts or exertion. The continuous

measurement of pves also allows the detection of detrusor contractions. In this article we will

refer to its terminology, the necessary equipment to carry it out, the examination technique,

its morphology in women and men, and the stress urethral pressure profile in women. The

most important parameter is the “maximum urethral closure pressure”, which is the maximum

difference between pura and pves; a value ≤ 20 cm H2O participates in the urodynamic definition

of intrinsic sphincter deficiency (together with an abdominal leak point pressure ≤ 60 cm H2O).

However, it must be taken into account that the different techniques used for its measurement

has led to inconsistent results, which makes their acceptance in clinical practice difficult.

rain metastases represent a critical stage of oncological disease and its frequency is

increasing over the recent years. The treatment of brain metastases has moved from a

conservative approach to an active management that should be individualized for each patient:

in case of single brain metastasis, surgery or radiosurgery should be considered as first option

of treatment; in case of multiple lesions, whole-brain radiotherapy is the standard of care. The

aim of this review is to present general aspects including new approaches in management of

patients with brain metastases.
Calprotectina fecal: utilidad en el diagnóstico diferencial de enfermedad inflamatoria intestinal y síndrome intestino irritable en adultos
Authors: Covarrubias R. Natalia , Madrid S. Ana María , Rojas B. René , Gompertz G. Macarena
Published: June 2023

Differentiation between inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) can be complex as their symptoms are often similar and unspecific. Fecal biomarkers could be useful to select patients with suspected organic diseases for colonoscopy, with the aim to improve early diagnosis and to avoid unnecessary invasive studies. Fecal calprotectin (FC) is a protein found mainly in neutrophils that is released into the feces as a result of cell disruption and apoptosis. Currently, FC is a simple and non-invasive biomarker of intestinal inflammation. Inflammatory gastrointestinal disorders are associated with high levels of FC, as occurs in IBD. This review focuses on FC as a useful tool for differential diagnosis between IBS and IBD in adults.

Terapia de ondas de choque en patología músculo-esquelética
Authors: Gohurdett J. Constanza , Amador C. Paola , Ruiz R. Delia
Published: June 2023

Extracorporeal shock waves are unique sound waves that generate a rapid increase in pressure in the tissues in which they are applied. They were first used on the management of urolithiasis and later spread to other pathologies such as musculoskeletal. A series of studies have been carried out to support the usefulness of shock waves in patients with plantar fasciitis, Achilles tendinopathy, epicondylitis, rotator cuff injury with or without calcification, patellar tendinopathy and peritrochanteric pathology that has lasted more than three months and have not responded to the initial handling. There is no consensus regarding the specific protocols to be used. In these conditions, shock waves are only a part of a comprehensive treatment, and should always be associated with other conventional therapies.

Manual wheelchair is one the most used mobility device in people that is unable to walk.

It enhances functional independence in non ambulant people, but it costs a great energy

expenditure and is a source of painful musculoskeletal injuries. The most frequently affected

joint in manual wheelchair users is the shoulder (rotator cuff tendinopathy and subacromial

impingement). In this review, we aim to describe the risk factors and biomechanical issues that

make wheelchair users more prone to develop shoulder pain. Further, we discuss potencial

approaches for the prevention and early treatment of these injuries.

Published: June 2023

Osteoarthrosis of the knee is one of the most important causes of disability around the world,
being total knee arthroplasty (TKA) a cost-effective surgical procedure for treating its severe
stage when all knee compartments are compromised. Despite the good functional results and
good survival of the implants and of the patients, still, 15 to 20% of the patients are dissatisfied
after surgery. One of the causes of dissatisfaction is persistent pain located in the anterior part
of the knee, which leads to controversy over whether to perform the patellar replacement.
Advantages and complications are described in both scenarios, and neither is superior to the
other in pain and implant survival. In the case of TKA without patellar replacement, the position
of the femoral component plays a crucial role in achieving normal patellar tracking. The current
challenge is to determine those clinical and radiological variables that allow us to predict the
absence of long-term anterior pain in patients who require TKA and who do not undergo patellar
replacement.

Role Of Women Leadership Attributes In Defense Services
Authors: Nautiyal Mayank
Published: June 2023

In certain settings, women really do better than males. Women's participation in the military would quadruple the number of qualified candidates for sensitive positions that need people skills. Armed forces are better able to put their finest and most diplomatic troops to work to rapidly resolve conflicts when they have access to a larger pool of potential recruits. Restricting women from serving in combat perpetuates sexism since it is widely accepted that combat experience is a prerequisite for advancement to senior officer posts. In the military, women must be subjected to the same dangers as males if they are to be afforded the same chances.

Η έννοια του λάθους κατά την εκμάθηση της γλώσσας-στόχου είναι παρεξηγημένη. Το λάθος μπορεί να βοηθήσει τη διαδικασία εκμάθησης μιας ξένης γλώσσας, δίνοντας ανατροφοδότηση τόσο στον μαθητή όσο και στον δάσκαλο. Για το σκοπό αυτό, αναπτύχθηκε η μέθοδος: Ανάλυση Λαθών. Η Ανάλυση Λαθών είναι μια πολύπλοκη και χρονοβόρα διαδικασία, η οποία, ωστόσο, βοηθά πάρα πολύ στην εκπαιδευτική διαδικασία. Συνήθως γίνεται με την ολοκλήρωση μιας εξέτασης/δοκιμασίας που έχει προετοιμαστεί ειδικά για το σκοπό αυτό. Μετά την ολοκλήρωση της δοκιμασίας, εντοπίζονται τα σφάλματα που έχουν βρεθεί σε αρκετά υψηλή συχνότητα και έκταση. Στη συνέχεια, γίνεται προσπάθεια να δικαιολογηθεί το λάθος κατηγοριοποιώντας ταυτόχρονα σε ενδογλωσσικά και διαγλωσσικά λάθη. Σε αυτό το άρθρο, ακολουθήθηκε η παραπάνω διαδικασία σχετικά με το σύστημα των πτώσεων της τουρκικής γλώσσας και την κατανόηση αυτών των περιπτώσεων από μαθητές της ελληνικής γλώσσας. Η χρήση αυτής της μεθόδου σε αυτό το γραμματικό θέμα της τουρκικής είναι ενδιαφέρουσα, καθώς η ελληνική γλώσσα δεν έχει πέντε πτώσης όπως η τουρκική. Έτσι, ο τρόπος σκέψης στα ελληνικά και η προσπάθεια παραγωγής λόγου στα τουρκικά έχει δείξει κάποια λάθη που έχουν γλωσσική σημασία για περαιτέρω δικαιολόγηση του λάθους.

Published: June 2023

High morbidity rates are associated with inflammatory bowel diseases such as Crohn's disease and ulcerative colitis. New studies have suggested that dysbiosis may play a role in the etiology of inflammatory bowel disease, although the cause of IBD remains unknown. Several disease pathologies, such as inflammatory bowel disease, have been associated with the intestinal microbiota, a metabolic organ with multiple physiological functions. This review summarizes the present level of knowledge regarding the impact of altered gut microbiota in inflammatory bowel disease, the mechanisms by which this occurs, and the potential significance of therapeutic methods based on gut microbiota in the prevention and treatment of IBD. It has been demonstrated that directly targeting the intestinal microbiota can treat both inflammatory bowel disease and colitis in humans and animals. To characterize the core microbiome associated with IBD and the underlying pathophysiology, however, additional research employing well-designed randomized control trials and animal models is required, as there are currently insufficient data and contradictory results from previous studies. The environment will influence the probiotic and prebiotic treatment for IBD.

Ambivalencias en la educación de migrantes en escuelas medias de la Ciudad Autónoma de Buenos Aires
Authors: González Mariana Alejandra
Published: June 2023

La educación es considerada un derecho humano según la Declaración Universal de 1948. En el caso de Argentina, aparece legislada por la Ley de Educación Nacional (2006), que así la garantiza para todas y todos los habitantes del país, sin importar su situación  regulatoria y en condiciones de igualdad. Del mismo modo, se expresa la Ley de Migración Nacional (2003), sin embargo, las trayectorias de jóvenes migrantes en escuelas medias de la Ciudad Autónoma de Buenos Aires, visibilizan tendencias que denuncian su no garantía. Este trabajo recupera ciertos antecedentes en la temática, a fin de reflexionar acerca de aspectos estructurales, vinculados al propio sistema educativo y subjetivo en torno a vivencias relacionales y en el marco de proyectos migratorios familiares, que conducen a una ambivalencia en la desigualdad de dichas trayectorias. En la conclusión se ubica  al contundente desafío y obligación de diseñar estrategias institucionales que incluyan sin asimilar, a las juventudes migrantes, a fin de alojarlas en respeto a sus singularidades.

Abstract: This paper reviews the theoretical and experimental researches on Argon Power Cycle (APC) engines. Hydrogen-fueled APC is an innovative power system for a high efficiency and zero emissions, which employs argon rather than nitrogen as a diluent. Due to the large specific heat ratio of argon, the thermodynamic efficiency of APC engines is significantly higher compared to conventional internal combustion engines. However, APC engines face the challenge of knock inhibition, especially when using hydrogen as a fuel. Therefore, this paper summarizes the strategies and technologies to suppress the knock of hydrogen-fueled APC engines, including using alternative fuels with greater anti-knock capacity, lean combustion, and water injection. Furthermore, some guidance opinions are also provided for reference about the development and industrialization of APC engines, such as ultra-lean combustion, which uses pistons with thermal insulation coatings, employing low-friction lubricants, and developing efficient multi-component membrane separation system for argon separation.

Abstract: The prevailing transportation uses internal combustion engines powered by fossil fuels that bear the reputation of carbon dioxide release among other harmful emissions. As an alternative, dimethyl ether (DME) has shown a high potential to mitigate emission challenges. The properties of DME present a highly reactive and volatile fuel suitable for clean combustion. However, the onboard handling of liquified DME is an ongoing challenge, especially for high-pressure direct injection applications. This paper aims to evaluate the sustainability, fuel handling, and combustion characteristics of DME as a clean and efficient fuel for sustainable on-road transportation. Strategies toward integrating DME fuel for automotive applications are emphasized. An overview of DME production is provided with relevance to current industry practices. Thereafter, the chemical and physical properties of DME are highlighted. The handling challenges of DME are accentuated, and accordingly, recommendations are made for setting up fuel management systems applicable to on-road engines and research laboratories. The DME fueling configurations, e.g., port injection and direct injection, are summarized. Empirical tests studied the engine and emission performance of DME combustion. Ultra-low NOx and smoke emissions, with high combustion efficiency, are achieved.
PER UN’ANALISI DELLA VITALITÀ DELLA LINGUA ITALIANA NEL MONDO
Authors: Dolci Roberto
Published: June 2023

Il contributo intende applicare il modello C.O.D. (Capacity , Opportunity, Desire) allo studio della lingua italiana in alcuni contesti specifici. Il modello è stato sviluppato da Grin (1990, 2003) e poi successivamente da Grin e Vaillancourt (1998) e Lo Bianco (2008 con lo scopo di analizzare la vitalità di una lingua in un determinato contesto. Il modello verrà applicato in particolare al contesto statunitense, ma verranno anche presi in considerazione altri contesti, in particolare quelli in cui è presente una forte comunità italiana. L’ipotesi che si intende verificare è che lo studio della lingua italiana all’estero è vitale proprio grazie alla presenza di una comunità di persone di origine italiana i cui discendenti non solo vogliono studiare italiano, ma che anche contribuiscono a promuoverlo efficacemente presso coloro che non hanno nessun rapporto con l’Italia se non quello di voler entrare a far parte di quella comunità immaginata, definita con il termine di italicità (Bassetti 2015) che condivide i valori a cui è associata l’immagine dell’Italia. La conclusione è quindi quella di ridefinire il concetto di Heritage Language Learner fino a comprendere anche questi ultimi dentro quello più ampio di apprendente culturalmente connesso alla lingua e quindi di Heritage Language and Culture Learner.

 

For an analysis of the vitality of the Italian language in the world

The paper applies the C.O.D. (Capacity , Opportunity, Desire) model to the study of the Italian language in some specific contexts. The model was developed by Grin (1990, 2003) and then later by Grin and Vaillancourt (1998) and Lo Bianco (2008 with the aim of investigating the vitality of a language in a given context. The model will be applied specifically on the U.S. context, but other contexts will also be considered, particularly those in which there is a strong Italian community. The hypothesis that will be tested is that the study of the Italian language abroad is vital precisely because of the presence of a community of people of Italian origin whose descendants not only want to study Italian, but who also help to promote it effectively to those who have no relationship with Italy other than wanting to become part of the imagined community defined by the term italicity (Bassetti 2015) that shares the values associated with the image of Italy. The conclusion is therefore to redefine the concept of Heritage Language Learner to include them within the broader concept of culturally connected language learner and thus to define them as Heritage Language and Culture Learners.
“NUOVI” ITALIANI TRA ITALIA E CINA: LINGUA E IDENTITÀ DI UNA NUOVA ITALIANITÀ
Authors: Ni Yang , Vallini Letizia
Published: June 2023

L’Italia, con la sua posizione strategica dal punto di vista geopolitico ed economico, è da più di trent’anni meta d’immigrazione, pur continuando al contempo a essere paese di emigrazione. Sebbene la Cina del XXI secolo non si collochi tra i primi Paesi quale meta d’emigrazione italiana, nell’ultimo decennio la presenza della popolazione italiana in Cina è in continuo aumento. Il presente contributo si propone di delineare un profilo sociolinguistico degli emigrati italiani in Cina, in cui si vuole mettere in luce non solo la vitalità e la dinamicità delle varietà dell’italiano, ma anche il contatto tra la comunità italiana e le varietà del paese ospitante. L’indagine si concluderà con uno studio di caso basato su un’intervista qualitativa a una coppia genitore-figlio rappresentanti la prima e seconda generazione di emigrati italiani in Cina. L’intervista è finalizzata ad approfondire l’importanza delle varietà dell’italiano nella trasmissione intra-familiare e nella vita quotidiana, e come la lingua possa plasmare il processo di creazione dell’identità personale.”

 

“New” Italians between Italy and China: language and identity of a new italianity

Italy, with its strategic position from a geopolitical and economic point of view, has been a destination for immigrants for more than thirty years, while also continuing to be a country of emigration. Although 21st-century China does not rank among the first countries as a destination for Italian emigration, the presence of the Italian community in China has seen a continuous increase in the last decade. This contribution aims at outlining a sociolinguistic profile of Italian emigrants in China, in which we want to highlight not only the vitality and dynamism of the varieties of the Italian language but also the contact between the Italian community and the linguistic varieties of the host country. The contribution will end with a case study based on a qualitative interview with a parent-child pair representing the first and second generation of Italian emigrants in China. The interview aims at investigating the importance that the varieties of Italian have in intra-family transmission and daily life, and how a language can shape personal identity.
Historias interrumpidas: Fragmentariedad temporal y tecnodiversidad latinoamericana / Interrupted Histories: Temporal Fragmentariness and Latin American Technodiversity

A fin de profundizar la comprensión de las múltiples y crecientemente aceleradas transformaciones de la experiencia humana en el mundo moldeadas por desarrollos técnicos algorítmicamente articulados, entendemos que la distinción entre sistema y entorno—base de la teoría de modelos sociales desde la década de 1970—debe ser puesta en cuestión: no sólo la construcción de los modelos se ha transformado técnica y conceptualmente, sino que los mismos sistemas que se modelan, incluido el sistema-mundo, se hallan en un proceso de transformación radical.

En efecto: los mismos objetos técnicos tienden a la deslocalización, adquiriendo un carácter ambiental y un modo de existencia procesual capaz de condicionar de maneras específicas la constitución del mundo y la experiencia humana, lo cual impele a la adopción de perspectivas novedosas sobre el poder. En este marco, será un enfoque ecológico el que permita avanzar en la aprehensión de la relación entre sistema y proceso—ambiental—asumiendo la pregnancia ontológica de la segunda dimensión y, además, abordar de manera más adecuada las urgentes preguntas en torno a las relaciones de poder, las formas contemporáneas de subjetivación y las posibilidades de emergencia de procesos críticos y de transformación.

A este respecto, en principio, desarrollamos algunas consideraciones relevantes para tematizar “lo digital” en la contemporaneidad, marcando dimensiones ineludibles para reflexionar en torno al ubicuo fenómeno de digitalización de la vida  En segundo lugar, reconstruimos algunos elementos clave del pensamiento cibernético como paradigma interpretativo. Finalmente, enfatizando en la dimensión política, presentamos una serie de reflexiones en torno al concomitante carácter ambiental de los objetos técnicos y del poder, junto con la explicitación del potencial que, a nuestro entender, anida en la noción del entramado localizado de gubernamentalidades múltiples para el pensamiento político y la evaluación crítica de experiencias de articulación específica entre técnica y política.
