Effects of Vape Use on Oral Health: A Review of the Literature.

Background and Objectives: The widespread use of tobacco has evolved with the popularity of vapes, especially among young people, despite the lack of clarity in warnings about their risks. Studies indicate the need for more effective communication about the oral risks of vaping. In addition to systemic, respiratory, and cardiovascular effects, vaping is associated with an increased risk of gingivitis and periodontal disease as well as reduced antioxidant capacity of saliva. The objectives of this narrative review are to summarize the existing information in the literature on the effects of vaping at the oral level and to bring together knowledge about the mechanism of action of vaping in oral tissues. Materials and Methods: In the present study, articles were searched in PubMed, Elsevier Scopus, and Web of Science using the keywords "oral health", "vaping", and "vape". Studies published in the last 6 years that addressed the effects of oral vaping were selected, including comparisons among vape users, smokers, and non-smokers. Repeated articles, prior to 2017 and in languages other than English, were excluded. Two review authors (A.M.I and M.F.E.M) independently selected the papers based on titles and abstracts and conducted a full review of the remaining papers. In cases of disagreement, a third reviewer was used. Results: A total of 113 results were obtained, distributed as 16 from PubMed, 35 from Web of Science, and 62 from Elsevier Scopus. After removing duplicates, 67 articles were filtered by reviewing titles and abstracts, and finally, 22 articles were selected for comprehensive reading. Subsequently, eight of these articles were chosen for qualitative synthesis and are presented in standardized tables. The sample size of all included studies was composed of 31,647 participants, (14,477 male and 17,170 female) with a mean of 35.016 ± 7.57 years of age. Conclusions: This review indicates that the use of vapes is associated with an increased risk of periodontitis and caries. Although users experience more oral problems than non-smokers, these are less severe than those of traditional smokers. The widespread prevalence, especially among young people, highlights the urgency of awareness campaigns to warn of risks and understand potential harm.

Efecto del farmacéutico clínico en las reconsultas a los 30 días posalta del servicio de urgencias: ensayo clínico controlado / Effect of a clinical pharmacist on 30-day revisits following discharge from an emergency department: a randomized controlled clinical trial

Objetivos. Determinar el efecto de la inclusión del farmacéutico clínico en el servicio de urgencias (SU) en las reconsultas durante 30 días posalta y la satisfacción de los pacientes. Métodos. Ensayo clínico controlado, aleatorizado, paralelo y pragmático, realizado en el SU de un hospital universitario. Los pacientes reclutados fueron asignados aleatoriamente al grupo control (GC) que recibió la atención habitual o al grupo intervenido (GI) que recibió además la atención de un farmacéutico clínico, el cual se integró al equipo clínico para optimizar la selección, evaluación y educación farmacoterapéutica en el SU y al alta. El desenlace primario fue reconsultas no programadas 30 días posaltarelacionadas con la atención inicial al SU. Las diferencias entre grupos se analizaron por curvas de supervivencia de Kaplan-Meier y prueba de log-rank. La asociación entre intervención y tiempo al evento fue analizada mediante regresión multivariada de riesgos proporcionales de Cox y se expresó como hazard ratio ajustada (HRa). Resultados. Un total de 1.001 pacientes ingresaron al estudio (GI=500 y GC=501). Ambos grupos eran similares, predominaron las mujeres (61,5%), edad 51 años (RIC: 33-65). La intervención redujo significativamente las reconsultas a cualquier centro durante 30 días posalta comparado con GC [25 (6,3%) vs 66 (16,7%); HRa: 0,29 (IC 95%: 0,17-0,50)] y para el mismo centro [15 (3,0%) vs 32 (6,5%); HRa: 0,46 (IC 95%: 0,24-0,87)]. La satisfacción del usuario fue mayor en el GI que GC (87,2% vs 83,2%; p<0,05). Conclusiones. La inclusión del farmacéutico clínico en un SU reduce sustancialmente las reconsultas durante 30 días posalta y mejora la satisfacción de los usuarios. (AU)

Objectives. To evaluate a clinical pharmacist’s inclusion in emergency department (ED) care in terms of the effect on on 30-day revisits after discharge from the ED and patient satisfaction. Methods. Randomized, controlled parallel-group pragmatic trial in a university hospital ED. Recruited patients were randomly assigned to a control group for standard care only or an intervention group to receive standard care plus the attention of a clinical pharmacist integrated into the care team to optimize the selection and evaluation of medications and provide pharmacotherapeutic education on the patient’s discharge. The primary outcome was unplanned revisits within 30 days after discharge because of the same complaint that led to the initial ED visit. Between-group differences were analyzed with Kaplan-Meier survival curves and log-rank tests. The association between the intervention and time to the outcome event was explored with multivariate Cox proportional hazard regression analysis. Results. A total of 1001 patients were enrolled (intervention, 500; control, 501). Patients in both groups were similar. A majority were women (61.5%), and the median age (interquartile range) was 51 years (33-65 years). The pharmacist’s intervention significantly reduced the number of 30-day revisits to any ED: 25 (6.3%) revisited vs 66 (16.7%) in the control group. The adjusted hazard ratio (aHR) was 0.29 (95% CI, 0.17-0.50). Fifteen patients (3.0%) from the intervention group revisited the same ED vs 32 (6.5%) from the control group (aHR, 0.46 [95% CI, 0.24-0.87]). More patients expressed satisfaction in the intervention group (87.2%) than in the control group ( 83.2%) (P<.05). Conclusions. Including a clinical pharmacist in ED care substantially reduces the number of 30-day revisits and increases patient satisfaction. (AU)

Longitudinal study of peer victimization, social support, and mental health during early adolescence.

BACKGROUND: Peer victimization predicts the development of mental health symptoms in the transition to adolescence, but it is unclear whether and how parents and school environments can buffer this link. METHODS: We analyzed two-year longitudinal data from the Adolescent Brain Cognitive Development (ABCD) study, involving a diverse sample of 11 844 children across the United States (average at baseline = 9.91 years; standard deviation = 0.63; range = 8.92-11.08; complete case sample = 8385). Longitudinal associations between peer victimization and two-year changes in mental health symptoms of major depression disorder (MDD), separation anxiety (SA), prodromal psychosis (PP), and attention-deficit/hyperactivity disorder (ADHD) were examined including a wide range of covariates. Mixed linear models were used to test for the moderating effects of parental warmth and prosocial school environment. RESULTS: 20% of children experienced peer victimization. Higher exposure to peer victimization was associated with increases in MDD, SA, and ADHD symptoms. Parental warmth was associated with decreases in MDD symptoms but did not robustly buffer the link between peer victimization and mental health symptoms. Prosocial school environment predicted decreases in PP symptoms and buffered the link between peer victimization and MDD symptoms but amplified the link between peer victimization and SA and ADHD symptoms. CONCLUSIONS: Peer victimization is associated with increases in mental health symptoms during the transition to adolescence. Parental warmth and prosocial school environments might not be enough to counter the negative consequences of peer victimization on all mental health outcomes.

Diagnóstico mediante resección endoscópica de una entidad extraña / Gastric lymphangioma. Diagnosis by endoscopic resection of a foreign entity

The lymphangioma is a rare and very uncommon benign tumor at the gastric level. Its diagnosis typically involves imaging tests and endoscopy, and its treatment usually involves surgery. We present a case of an 82-year-old patient who presented with chronic anemia, with a large gastric polyp detected during the initial gastroscopy. Subsequently, an endoscopic resection was performed, confirming histologically that it was a lymphangioma.(AU)

An updated examination of the perception of barriers for pharmacogenomics implementation and the usefulness of drug/gene pairs in Latin America and the Caribbean.

Pharmacogenomics (PGx) is considered an emergent field in developing countries. Research on PGx in the Latin American and the Caribbean (LAC) region remains scarce, with limited information in some populations. Thus, extrapolations are complicated, especially in mixed populations. In this paper, we reviewed and analyzed pharmacogenomic knowledge among the LAC scientific and clinical community and examined barriers to clinical application. We performed a search for publications and clinical trials in the field worldwide and evaluated the contribution of LAC. Next, we conducted a regional structured survey that evaluated a list of 14 potential barriers to the clinical implementation of biomarkers based on their importance. In addition, a paired list of 54 genes/drugs was analyzed to determine an association between biomarkers and response to genomic medicine. This survey was compared to a previous survey performed in 2014 to assess progress in the region. The search results indicated that Latin American and Caribbean countries have contributed 3.44% of the total publications and 2.45% of the PGx-related clinical trials worldwide thus far. A total of 106 professionals from 17 countries answered the survey. Six major groups of barriers were identified. Despite the region's continuous efforts in the last decade, the primary barrier to PGx implementation in LAC remains the same, the "need for guidelines, processes, and protocols for the clinical application of pharmacogenetics/pharmacogenomics". Cost-effectiveness issues are considered critical factors in the region. Items related to the reluctance of clinicians are currently less relevant. Based on the survey results, the highest ranked (96%-99%) gene/drug pairs perceived as important were CYP2D6/tamoxifen, CYP3A5/tacrolimus, CYP2D6/opioids, DPYD/fluoropyrimidines, TMPT/thiopurines, CYP2D6/tricyclic antidepressants, CYP2C19/tricyclic antidepressants, NUDT15/thiopurines, CYP2B6/efavirenz, and CYP2C19/clopidogrel. In conclusion, although the global contribution of LAC countries remains low in the PGx field, a relevant improvement has been observed in the region. The perception of the usefulness of PGx tests in biomedical community has drastically changed, raising awareness among physicians, which suggests a promising future in the clinical applications of PGx in LAC.

Role of Dentistry in Humanitarian Projects: Knowledge and Perspective of Future Professionals on the World of Volunteering in Spain.

Non-governmental organizations (NGOs) in dentistry seek to promote the improvement on oral health in the most disadvantaged regions. The objective of this study is to identify the level of knowledge, expectations, and motivations that dental school students have about volunteering in dentistry, as well as to evaluate possible differences in these variables depending on their level of dental training. During the month of September 2022, a voluntary and anonymous online survey was carried out among all the students at the Dentistry School of Oviedo University. There were 5 questions to judge knowledge about global oral health course. 12 additional questions were included to assess the willingness to volunteer in international setting, the volunteer profile, as well as the most effective means to improve oral health in host communities. None of the students from our center had participated as a volunteer in dental NGOs, but up to 64.4% of them had considered their collaboration. The level of knowledge about global oral health obtained was low, with the percentage of correct answers ranging between 14.4% (in the question about the ideal patient/dentist ratio) and 57.8% (in the question about the fluoride concentration in drinking water). Majority of dental students (98.9%) were not aware that basic package of oral care was created by WHO. Significantly, the students of the clinical courses showed a greater motivation to volunteer.

Can emotional acceptance buffer the link between executive functioning and mental health in late life?

Emotional acceptance is thought to play an important role in protecting mental health. However, few studies have examined emotional acceptance among older adults who may experience declines in functioning, including executive functioning. The present laboratory-based study examined whether emotional acceptance and (to determine specificity) detachment and positive reappraisal moderated links between executive functioning and mental health symptoms in a sample of healthy older adults. Emotion regulation strategies were measured using questionnaire-based measures (using established questionnaires) as well as performance-based measures (instructing individuals to use emotional acceptance, detachment, and positive reappraisal in response to sad film clips). Executive functioning was measured using a battery of working memory, inhibition, and verbal fluency tasks. Mental health symptoms were measured using questionnaires to assess anxiety and depressive symptoms. Results showed that (a) emotional acceptance moderated the link between executive functioning and mental health such that lower executive functioning predicted higher levels of anxiety and depressive symptoms at low but not at high levels of emotional acceptance. Moderation effects tended to be (b) stronger for emotional acceptance compared to the other emotion regulation strategies (though not all comparisons were statistically significant). Findings were (c) robust when controlling for age, gender, and education for questionnaire-based (but not performance-based) emotional acceptance. These findings contribute to the literature on emotion regulation specificity and highlight the mental health benefits of emotional acceptance in the face of low executive functioning.

Analysis of the esthetic preferences of Spanish laypersons and dentists regarding the different width proportions of the maxillary anterior teeth.

STATEMENT OF PROBLEM: Multiple esthetic width proportions have been described for maxillary anterior teeth. However, the esthetic characteristics of each have not been compared simultaneously to determine which proportion is preferred by dentists and laypersons. PURPOSE: The purpose of this study was to evaluate the preferences of dentists and laypersons with respect to internationally recognized dental esthetic proportions. It also sought to determine whether a relationship existed among dentists' preferences as per their specialty and among laypersons as per their academic field. MATERIAL AND METHODS: Two smile images, one male and one female, were digitally modified to meet the golden proportion and the recurring esthetic dental (70%) and golden percentage. The 2 resulting sets of images (original images and digitally altered ones) were presented to dentists and laypersons through a Web-based survey site. The Pearson chi-squared and Fisher tests were used to assess the differences in the esthetic preferences among the groups (α=.05). RESULTS: A total of 363 answers were obtained from dentists and 750 from laypersons. Both groups considered recurring esthetic dental to be the most esthetic proportion and golden proportion to be the least esthetic proportion. The dentists' preferences as per their specialty followed the same trend, whereas the laypersons' preferences were more scattered according to their academic field. The recurring esthetic dental proportion was preferred in images of both sexes, golden proportion smiles were the least preferred for female smiles, and golden percentage was the least preferred for male smiles. CONCLUSIONS: The results obtained indicated that the preferred esthetic proportion both for dentists and laypersons was the recurring esthetic dental 70%, with the dentists' specialty or laypersons branch of knowledge not affecting choice.

Lilian Harrison y la travesía del Río de la Plata (1923): repercusión en la prensa uruguaya / Lilian Harrison e a travessia do Rio da Prata (1923): repercussão na imprensa uruguaia / Lilian Harrison and the crossing of the River Plate (1923): repercussion in the Uruguayan press

RESUMEN Lilian Harrison fue la primera persona en completar la travesía del Río de la Plata a nado, entre Colonia (Uruguay) y Punta Lara (Argentina) en 1923. La prensa argentina de la época coronó la victoria como un logro de toda la nación, a despecho de las apelaciones sexistas de los reportajes. Este artículo pretende analizar los discursos de la prensa uruguaya sobre la hazaña de la nadadora, utilizando las principales publicaciones periódicas de la época. El análisis de los reportajes permite concluir que, además de los artículos sexistas, que disminuían los logros de la atleta en comparación con sus compañeros masculinos, había cierto nivel de contrariedad en los reportajes, lo que indicaba el desagrado de la prensa hacia los propios nadadores del país.

ABSTRACT Lilian Harrison was the first person to complete the crossing of the River Plate by swimming between Colonia (Uruguay) and Punta Lara (Argentina) in 1923. The Argentine press of the time crowned the victory as an achievement of the whole nation, despite the sexist appeals of the reports. This article aims to analyse the discourses of the Uruguayan press about the swimmer's achievement, using the main periodicals published at the time. An analysis of the reports allows us to conclude that, in addition to the sexist articles, which also diminished the athlete's achievements compared to her male companions, there was some level of contrariness in the reports, signalling the displeasure of the press towards the country's swimmers.

RESUMO Lilian Harrison foi a primeira pessoa a completar a Travessia do Rio da Prata à nado, entre Colônia (Uruguay) e Punta Lara (Argentina) no ano de 1923. A imprensa argentina da época coroou a vitória como uma conquista de toda a nação, em que pesem os apelos sexistas das reportagens. Esse artigo tem como objetivo analisar os discursos da imprensa Uruguaya sobre o feito da nadadora, utilizando os principais periódicos publicados na época. Uma análise das reportagens permite concluir que, para além das matérias sexistas, que também diminuíram os feitos da atleta frente aos companheiros do gênero masculino, houve algum nível de contrariedade nas reportagens, sinalizando o desagrado da imprensa em relação aos próprios nadadores do país.

Treatment alternatives for dry mouth: A scoping review.

Background: Saliva is a biological fluid essential for the maintenance of a proper oral health. Its absence predisposes to differences pathologies, including dental caries, fungal infections among many others, significantly affecting the oral health related quality of life (OHRQoL). There is a large variety of treatment alternatives available for dry mouth, which increases constantly. Objective: To identify new treatment alternatives for dry mouth. Material and Methods: We conducted a systematic search in PubMed/MEDLINE, Web of Science, Scopus and Ebsco. Articles published between January 2015 and January 2020 were retrieved and reviewed by two independent evaluators. Results: Nineteen studies met the inclusion criteria and were included for analysis. Local therapies were the most evaluated agents, followed by systemic and non-conventional treatments. Most local therapies showed certain utility for the management of dry mouth and the improvement of OHRQoL. These formulations were mainly based on natural agents, including malic acid, thyme honey, ginger, among others. Conclusions: Local agents are first line treatment alternatives for dry mouth sensation, with a reported efficiency that varies between studies, and with a low number of reported adverse side-effects. Nevertheless, care must be taken when interpreting these results, as is difficult to compare studies within each other due large heterogeneity in study design and outcomes being measured. Key words:Xerostomia, dry mouth, hyposalivation, saliva, mouth dryness.

Analysis of dental esthetic proportions in a Spanish population sample.

PURPOSE: The present study aimed to analyze in a Spanish population sample the compliance of the anterior maxillary teeth to the dental esthetic proportions described in the literature. METHODS: Photographs of the smiles of 78 individuals were calibrated and digitally analyzed considering the following proportions: golden proportion (GP), recurring esthetic dental (RED), golden percentage (GPG), Preston's proportion and Modified golden percentage (MGPG). For statistical analysis, the t-test of an independent sample was applied, and compliance percentages for each standard were recorded. RESULTS: The existence of RED 70% or 80% has not been registered. The percentages of compliance with GP were within a range between 0% and 16%. The mean tooth width ratios were adjusted to the values described by Preston (P > 0.05), but the compliance percentages were low (3.33-25%). GPG only presented high percentages of compliance in the lateral incisors (53.33-62.5%). MGPG showed the highest percentages of compliance (50-68%). CONCLUSION: After analyzing a Spanish population sample using smile photographs for the first time, GP, RED, GPG and Preston's proportion standards are not fulfilled and therefore, not suitable for treatments that seek a smile that reproduces natural principles. However, the values designated by MGPG with a deviation of ±1% are largely applicable for treatments that aim for a natural smile.

Two-Dimensional Analysis of Digital Images through Vector Graphic Editors in Dentistry: New Calibration and Analysis Protocol Based on a Scoping Review.

This review was carried out to analyse the functions of three Vector Graphic Editor applications (VGEs) applicable to clinical or research practice, and through this we propose a two-dimensional image analysis protocol in a VGE. We adapted the review method from the PRISMA-ScR protocol. Pubmed, Embase, Web of Science, and Scopus were searched until June 2020 with the following keywords: Vector Graphics Editor, Vector Graphics Editor Dentistry, Adobe Illustrator, Adobe Illustrator Dentistry, Coreldraw, Coreldraw Dentistry, Inkscape, Inkscape Dentistry. The publications found described the functions of the following VGEs: Adobe Illustrator, CorelDRAW, and Inkscape. The possibility of replicating the procedures to perform the VGE functions was analysed using each study's data. The search yielded 1032 publications. After the selection, 21 articles met the eligibility criteria. They described eight VGE functions: line tracing, landmarks tracing, linear measurement recording, angular measurement recording, image calibration, image overlay, file transfer, and vector graphics development. The features offered by the VGEs bring great precision and objectivity to two-dimensional image analysis. The image analysis and editing procedures are currently not protocolised. Thus, a protocol for image calibration and measurement recording is proposed in order to guarantee the protocol's replication.

Advantages of 18F-FDG PET/CT Imaging over Modified Duke Criteria and Clinical Presumption in Patients with Challenging Suspicion of Infective Endocarditis.

According to European Society of Cardiology guidelines (ESC2015) for infective endocarditis (IE) management, modified Duke criteria (mDC) are implemented with a degree of clinical suspicion degree, leading to grades such as "possible" or "rejected" IE despite a persisting high level of clinical suspicion. Herein, we evaluate the 18F-FDG PET/CT diagnostic and therapeutic impact in IE suspicion, with emphasis on possible/rejected IE with a high clinical suspicion. Excluding cases of definite IE diagnosis, 53 patients who underwent 18F-FDG PET/CT for IE suspicion were selected and afterwards classified according to both mDC (possible IE/Duke 1, rejected IE/Duke 0) and clinical suspicion degree (high and low IE suspicion). The final status regarding IE diagnosis (gold standard) was based on the multidisciplinary decision of the Endocarditis Team, including the 'imaging specialist'. PET/CT images of the cardiac area were qualitatively interpreted and the intensity of each focus of extra-physiologic 18F-FDG uptake was evaluated by a maximum standardized uptake value (SUVmax) measurement. Extra-cardiac 18F-FDG PET/CT pathological findings were considered to be a possible embolic event, a possible source of IE, or even a concomitant infection. Based on the Endocarditis Team consensus, final diagnosis of IE was retained in 19 (36%) patients and excluded in 34 (64%). With a sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and global accuracy of 79%, 100%, 100%, 89%, and 92%, respectively, PET/CT performed significantly better than mDC (p = 0.003), clinical suspicion degree (p = 0.001), and a combination of both (p = 0.001) for IE diagnosis. In 41 patients with possible/rejected IE but high clinical suspicion, sensitivity, specificity, PPV, NPV, and global accuracies were 78%, 100%, 100%, 85%, and 90%, respectively. Moreover, PET/CT contributed to patient management in 24 out of 53 (45%) cases. 18F-FDG PET/CT represents a valuable diagnostic tool that could be proposed for challenging IE cases with significant differences between mDC and clinical suspicion degree. 18F-FDG PET/CT allows a binary diagnosis (definite or rejected IE) by removing uncertain diagnostic situations, thus improving patient therapeutic management.

Toward the discovery of biological functions associated with the mechanosensor Mtl1p of Saccharomyces cerevisiae via integrative multi-OMICs analysis.

Functional analysis of the Mtl1 protein in Saccharomyces cerevisiae has revealed that this transmembrane sensor endows yeast cells with resistance to oxidative stress through a signaling mechanism called the cell wall integrity pathway (CWI). We observed upregulation of multiple heat shock proteins (HSPs), proteins associated with the formation of stress granules, and the phosphatase subunit of trehalose 6-phosphate synthase which suggests that mtl1Δ strains undergo intrinsic activation of a non-lethal heat stress response. Furthermore, quantitative global proteomic analysis conducted on TMT-labeled proteins combined with metabolome analysis revealed that mtl1Δ strains exhibit decreased levels of metabolites of carboxylic acid metabolism, decreased expression of anabolic enzymes and increased expression of catabolic enzymes involved in the metabolism of amino acids, with enhanced expression of mitochondrial respirasome proteins. These observations support the idea that Mtl1 protein controls the suppression of a non-lethal heat stress response under normal conditions while it plays an important role in metabolic regulatory mechanisms linked to TORC1 signaling that are required to maintain cellular homeostasis and optimal mitochondrial function.

Pharmacogenetics-Based Preliminary Algorithm to Predict the Incidence of Infection in Patients Receiving Cytotoxic Chemotherapy for Hematological Malignancies: A Discovery Cohort.

Introduction: Infections in hematological cancer patients are common and usually life-threatening; avoiding them could decrease morbidity, mortality, and cost. Genes associated with antineoplastics' pharmacokinetics or with the immune/inflammatory response could explain variability in infection occurrence. Objective: To build a pharmacogenetic-based algorithm to predict the incidence of infections in patients undergoing cytotoxic chemotherapy. Methods: Prospective cohort study in adult patients receiving cytotoxic chemotherapy to treat leukemia, lymphoma, or myeloma in two hospitals in Santiago, Chile. We constructed the predictive model using logistic regression. We assessed thirteen genetic polymorphisms (including nine pharmacokinetic-related genes and four inflammatory response-related genes) and sociodemographic/clinical variables to be incorporated into the model. The model's calibration and discrimination were used to compare models; they were assessed by the Hosmer-Lemeshow goodness-of-fit test and area under the ROC curve, respectively, in association with Pseudo-R2. Results: We analyzed 203 chemotherapy cycles in 50 patients (47.8 ± 16.1 years; 56% women), including 13 (26%) with acute lymphoblastic and 12 (24%) with myeloblastic leukemia. Pharmacokinetics-related polymorphisms incorporated into the model were CYP3A4 rs2242480C>T and OAT4 rs11231809T>A. Immune/inflammatory response-related polymorphisms were TLR2 rs4696480T>A and IL-6 rs1800796C>G. Clinical/demographic variables incorporated into the model were chemotherapy type and cycle, diagnosis, days in neutropenia, age, and sex. The Pseudo-R2 was 0.56, the p-value of the Hosmer-Lemeshow test was 0.98, showing good goodness-of-fit, and the area under the ROC curve was 0.93, showing good diagnostic accuracy. Conclusions: Genetics can help to predict infections in patients undergoing chemotherapy. This algorithm should be validated and could be used to save lives, decrease economic costs, and optimize limited health resources.
