Conducting co-creation for public health in low and middle-income countries: a systematic review and key informant perspectives on implementation barriers and facilitators.

BACKGROUND: There has been an increase in the use of co-creation for public health because of its claimed potential to increase an intervention's impact, spark change and co-create knowledge. Still, little is reported on its use in low-and-middle-income countries (LMICs). This study offers a comprehensive overview of co-creation used in public-health-related interventions, including the interventions' characteristics, and reported implementation barriers and facilitators. METHODS: We conducted a systematic review within the Scopus and PubMed databases, a Google Scholar search, and a manual search in two grey literature databases related to participatory research. We further conducted eight interviews with first authors, randomly selected from included studies, to validate and enrich the systematic review findings. RESULTS: Through our review, we identified a total of twenty-two studies conducted in twenty-four LMIC countries. Majority of the interventions were designed directly within the LMIC setting. Aside from one, all studies were published between 2019 and 2023. Most studies adopted a co-creation approach, while some reported on the use of co-production, co-design, and co-development, combined either with community-based participatory research, participatory action research or citizen science. Among the most reported implementation barriers, we found the challenge of understanding and accounting for systemic conditions, such as the individual's socioeconomic status and concerns related to funding constraints and length of the process. Several studies described the importance of creating a safe space, relying on local resources, and involving existing stakeholders in the process from the development stage throughout, including future and potential implementors. High relevance was also given to the performance of a contextual and/or needs assessment and careful tailoring of strategies and methods. CONCLUSION: This study provides a systematic overview of previously conducted studies and of reported implementation barriers and facilitators. It identifies implementation barriers such as the setting's systemic conditions, the socioeconomic status and funding constrains along with facilitators such as the involvement of local stakeholders and future implementors throughout, the tailoring of the process to the population of interest and participants and contextual assessment. By incorporating review and interview findings, the study aims to provide practical insights and recommendations for guiding future research and policy.

A review of implementation and evaluation frameworks for public health interventions to inform co-creation: a Health CASCADE study.

BACKGROUND: By including the needs and perspectives of relevant stakeholders, co-creation is seen as a promising approach for tackling complex public health problems. However, recommendations and guidance on how to plan and implement co-creation are lacking. By identifying and analysing existing implementation and evaluation frameworks for public health, this study aims to offer key recommendations for professional stakeholders and researchers wanting to adopt a co-creation approach to public health interventions. METHODS: Firstly, PubMed and CINAHL databases were screened for articles introducing original implementation and evaluation frameworks for public health interventions. Backwards snowballing techniques were applied to the included papers. Secondly, identified frameworks were classified and relevant data extracted, including steps and constructs present in the frameworks. Lastly, recommendations were derived by conducting thematic analysis on the included frameworks. RESULTS: Thirty frameworks were identified and data related to their nature and scope extracted. The frameworks' prominent steps and constructs were also retrieved. Recommendations related to implementation and evaluation in the context of co-creation were included. CONCLUSION: When engaging in co-creation, we recommend including implementation considerations from an early stage and suggest adopting a systems thinking as a way to explore multiple levels of influence, contextual settings and systems from an early planning stage. We highlight the importance of partnering with stakeholders and suggest applying an evaluation design that is iterative and cyclical, which pays particular attention to the experience of the engaged co-creators.

How Surgical Leaders Transform Their Residents to Craft Their Jobs: Surgeons' Perspective.

BACKGROUND: Surgeons should transform their residents to take the lead in their jobs and optimize their working conditions, so-called job crafting. We investigated the actions undertaken by surgeons with a transformational leadership style to encourage residents' job crafting, about which there is at present a paucity of information. METHODS: We performed a qualitative study based on principles of constructivist grounded theory. In-depth interviews were held with a purposive sample of surgeons who were perceived as transformational leaders by their residents. During data analysis (open, axial, and selective coding), we compared inductive codes with deductive codes drawn from the job demands-resources and transformational leadership theories to reach a consensus on the interpretation of data and identification of the main themes. RESULTS: Sixteen surgeons participated. Surgeons undertook five actions that enhanced job crafting in residents. They: one) modeled positive behaviors of a good surgeon; two) used a stepwise individual approach toward autonomy; three) connected with the resident as a person; four) supported residents in handling complications and errors; and five) they coached the resident to deal with competing interests. These actions had four consequences for residents. They led to: one) more responsibilities in patient care; two) more constructive relationships in the workplace; three) less pressure from workload and surgical care duties; and four) less personal difficulties and errors in patient care. CONCLUSIONS: The actions undertaken by surgeons with a transformational leadership style have a positive association with the residents' ability to craft their jobs. This knowledge has implications for surgeons' leadership development with a view to workplace education.

Extracellular enzymatic activity of two hydrolases in wastewater treatment for biological nutrient removal.

Due to the complex nature of the wastewater (both domestic and non-domestic) composition, biological processes are widely used to remove nutrients, such as carbon (C), nitrogen (N), and phosphorous (P), which cause instability and hence contribute to the damage of water bodies. Systems with different configurations have been developed (including anaerobic, anoxic, and aerobic conditions) for the joint removal of carbon, nitrogen, and phosphorus. The goal of this research is to evaluate the extracellular activity of ß-glucosidase and phosphatase enzymes in a University of Cape Town (UCT) system fed with two synthetic wastewaters of different molecular complexity. Both types of waters have medium strength characteristics similar to those of domestic wastewater with a mean C/N/P ratio of 100:13:1. The operation parameters were hydraulic retention time (HRT) of 10 h, solid retention time (SRT) of 12 days, mean concentration of the influent in terms of chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN), and total phosphorus (TP) of 600, 80, and 6 mg/L, respectively. According to the results obtained, statistically significant differences have been found in the extracellular enzyme activities with the evaluated wastewaters and in the units comprising the treatment system in some of the cases. An analysis of principal components showed that the extracellular enzymatic activity has been correlated to nutrient concentration in wastewater, biomass concentration in the system, and metabolic conditions of treatment phases. Additionally, this research has allowed determining an inverse relationship between wastewater biodegradability and the extracellular enzyme activity of ß-glucosidase and phosphatase. These results highlight the importance of including the analysis of biomass biochemical characteristics as control methods in wastewater treatment systems for the nutrient removal.

Nonatherosclerotic causes of acute coronary syndrome: recognition and management.

Acute coronary syndromes (ACS) frequently result from the rupture or erosion of a vulnerable coronary plaque, with associated intracoronary thrombosis. ACS also may occur in patients with angiographically normal coronary arteries. Some of these patients, however, still have angiographically silent underlying coronary artery disease. In this setting, subtle atherosclerotic changes frequently associated with unstable morphologic features or residual intracoronary thrombus may be detected with intracoronary imaging techniques. Nevertheless, other patients develop ACS as a result of nonatherosclerotic coronary artery disease (NA-CAD). ACS in patients with NA-CAD may be the consequence of coronary spasm or transient coronary embolic phenomena. In these patients, after the initial ischemic insult, late coronary angiography usually reveals normal epicardial coronary vessels. Kounis syndrome is a type of ACS generated by allergic reactions. Takotsubo cardiomyopathy is characterized by normal coronary arteries with a distinct pattern of transient left ventricular wall motion abnormalities. ACS also may occur in young patients following illicit drug use. Finally, spontaneous coronary artery dissection and intramural hematoma represent other etiologies of NA-CAD. In this review, we discuss current evidence regarding diagnostic and treatment strategies in patients presenting with ACS as a result of NA-CAD.

A Case of Vaping-Associated Candida and Herpes Simplex Virus (HSV) Co-infection Causing Esophagitis in an Immunocompetent Patient.

Electronic cigarettes (e-cigarettes) and vaping have gained popularity in the last two to five years as an alternative way of consuming nicotine, as well as tetrahydrocannabinol (THC), particularly in the younger population. Vaping/e-cigarettes heat nicotine/THC and other chemical components to create the vapor to be inhaled, which increases the risk of mucosal infection and esophagitis. Although tobacco smoking has been extensively studied and known to affect the oral cavity and esophagus, the effect of vaping is yet to be well-studied. We report a case of odynophagia secondary to esophageal candidiasis, herpes simplex virus (HSV) esophagitis, and reflux esophagitis associated with vaping.

The effect of bullying and cyberbullying on predicting suicide risk in adolescent females: The mediating role of depression.

This paper analyzed the role of depression as a mediator in the association between bullying, cyberbullying, and suicide risk in adolescent females. A total of 751 Colombian adolescent females (M= 13.71, SD=1.897), who were administered the Plutchik Suicide Risk Scale, the Beck Depression Inventory, the European Bullying Intervention Project Questionnaire and Cyberbullying. Bullying victimization and aggression and cyberbullying victimization were found to contribute statistically significant effects that explaining 22 % of the variance in depression. The variables of victimization in bullying and cyberbullying and depression explained 64 % of the variance in suicidal risk, and depression mediated the association between victim and aggressor roles in bullying and cyberbullying in predicting suicidal risk, whose total direct and indirect effects are statistically significant. The findings support the role of depression as a mediating variable between bullying and cyberbullying and suicidal risk in female adolescents and highlight the importance of focusing prevention and intervention efforts on risk factors for depression and suicidal behavior in cases of bullying and cyberbullying.

Atorvastatin-Associated Eosinophilic Spongiosis: A Case Report and a Relevant Literature Review of Dermatological Manifestations.

Atorvastatin, a widely prescribed 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitor (HMG-CoA reductase inhibitor), is associated with various adverse effects, including many dermatologic manifestations. We present the case of a 73-year-old man who developed eosinophilic spongiosis shortly after initiating atorvastatin therapy, an adverse effect which to our knowledge has not yet been reported in association with atorvastatin. Our investigation explores the clinical and histopathologic characteristics of eosinophilic spongiosis induced by atorvastatin, delving into potential mechanisms behind statin-induced eosinophilia. A literature review, focusing on atorvastatin's dermatological side effects, revealed a limited number of relevant studies, emphasizing the scarcity of documented cases. Our aim is to raise awareness of eosinophilic spongiosis as a potential side effect of atorvastatin, emphasizing its impact on patients' quality of life. This case prompts further research into the mechanisms underlying such dermatologic reactions, contributing to a better understanding of atorvastatin's diverse adverse effects.

Navigating process evaluation in co-creation: a Health CASCADE scoping review of used frameworks and assessed components.

BACKGROUND: Co-creation is seen as a way to ensure all relevant needs and perspectives are included and to increase its potential for beneficial effects and uptake process evaluation is crucial. However, existing process evaluation frameworks have been built on practices characterised by top-down developed and implemented interventions and may be limited in capturing essential elements of co-creation. This study aims to provide a review of studies planning and/or conducting a process evaluation of public health interventions adopting a co-creation approach and aims to derive assessed process evaluation components, used frameworks and insights into formative and/or participatory evaluation. METHODS: We searched for studies on Scopus and the Health CASCADE Co-Creation Database. Co-authors performed a concept-mapping exercise to create a set of overarching dimensions for clustering the identified process evaluation components. RESULTS: 54 studies were included. Conceptualisation of process evaluation included in studies concerned intervention implementation, outcome evaluation, mechanisms of impact, context and the co-creation process. 22 studies (40%) referenced ten existing process evaluation or evaluation frameworks and most referenced were the frameworks developed by Moore et al (14%), Saunders et al (5%), Steckler and Linnan (5%) and Nielsen and Randall (5%).38 process evaluation components were identified, with a focus on participation (48%), context (40%), the experience of co-creators (29%), impact (29%), satisfaction (25%) and fidelity (24%).13 studies (24%) conducted formative evaluation, 37 (68%) conducted summative evaluation and 2 studies (3%) conducted participatory evaluation. CONCLUSION: The broad spectrum of process evaluation components addressed in co-creation studies, covering both the evaluation of the co-creation process and the intervention implementation, highlights the need for a process evaluation tailored to co-creation studies. This work provides an overview of process evaluation components, clustered in dimensions and reflections which researchers and practitioners can use to plan a process evaluation of a co-creation process and intervention.

Urofacial (Ochoa) syndrome with a founder pathogenic variant in the HPSE2 gene: a case report and mutation origin.

Urofacial syndrome or Ochoa syndrome (UFS or UFOS) is a rare disease characterized by inverted facial expression and bladder dysfunction that was described for the first time in Colombia. It is an autosomal recessive pathology with mutations in the HPSE2 and LRIG2 genes. However, 16% of patients do not have any mutations associated with the syndrome. Despite the importance of neurobiology in its pathophysiology, there are no neurological, neuropsychological, or psychological studies in these patients. A 30-year-old male from Medellín, Colombia, with a significant perinatal history, was diagnosed with grade 4 hydronephrosis on his first ultrasound test. At 4 months of age, symptoms such as hypomimia, lagophthalmos, and recurrent urinary tract infections started to manifest. Imaging studies revealed urinary tract dilatation, vesicoureteral reflux, and a double collector system on his left side, which led to the diagnosis of UFS. Multiple procedures, including vesicostomy, ureterostomy, and enterocystoplasty, were performed. At 20 years of age, he achieved urinary sphincter control. Genetic analysis revealed a founder pathogenic variant, c.1516C > T (p.Arg506Ter), in the HPSE2 gene, which produces a truncated protein that lacks 86 amino acids. This variant is classified as pathogenic according to the ClinVar database for UFS. The mutation age is approximately 260-360 years, and the two alleles share a 7.2-7.4 Mb IBD segment. Moreover, we detected European local ancestry in the IBD segment, which is consistent with a Spanish introduction. Neurological examination, neuropsychological assessment, and psychological testing revealed no abnormalities, except for high stress levels. Clinical analysis of this patient revealed distorted facial expression and detrusor-sphincter dyssynergia, which are typical of patients with UFS. Genetic analysis revealed a pathogenic variant in the HPSE2 gene of European origin and a mutation age of 260-360 years. From a neurological, neuropsychological, and psychological (emotional and personality) perspective, the patient showed no signs or symptoms of clinical interest.

"Learning to learn" in the Extended Inverted Classroom: An evaluation of the effects of interactive teaching on knowledge and cognitive regulation in medical students.

INTRODUCTION: The evidence regarding the effects of the Inverted Classroom on students' metacognitive skills is limited. This study evaluates these effects on student perceptions about knowledge and cognitive regulation during a surgical course. METHODS: We measured student perceptions before and after a conventional Inverted Classroom in surgery using the Metacognitive Awareness Inventory. We evaluated the mean differences between the scores of the two measurements using Student's t-test (p < 0.05), and the size of the effect on knowledge and cognitive regulation using Cohen's d test (95%CI). RESULTS: A total of 158 students (pre-intervention) and 155 students (post-intervention) were included in the analysis. Significant differences were found (p < 0.05) in, as well as positive effects on, the students' abilities to know their own learning (declarative knowledge) (d = 0.24; 95%CI, 0.02-0.47), to use learning strategies (procedural knowledge) (d = 0.19; 95%CI, -0.02 to 0.41) and to understand when and why to use these strategies (conditional knowledge) (d = 0.20; 95%CI, -0.01 to 0.42), in addition to the abilities to plan (d = 0.31; 95%CI, 0.09-0.53) and to evaluate their learning (d = 0.31; 95%CI, 0.08-0.53). CONCLUSIONS: The Inverted Classroom has positive effects on metacognitive skills according to students' perceptions. Further studies are required that compare these effects with other methodologies for teaching in the classroom and the workplace.

Association of Strict Versus Lenient Cholesterol Lowering with Cardiac Outcomes, Diabetes Progression and Complications, and Mortality in Patients with Diabetes Treated with Statins: Is Less More?

INTRODUCTION: Whereas some guidelines recommend statin use to achieve low-density lipoprotein cholesterol (LDL-C) goal < 70 mg/dL for primary prevention of atherosclerotic cardiovascular disease (ASCVD) in patients at higher risk, others recommend against a target LDL-C level. Achieving a target level < 70 mg/dL commonly requires the use of high intensity statins, which has been associated with higher risk of diabetes progression. The objective of this study is to assess the association of strict (≤ 70 mg/dL) versus lenient (> 70 to100 mg/dL) LDL-C lowering on major adverse cardiovascular events (MACE), diabetes progression, diabetes microvascular complications, and total mortality in patients with diabetes. METHODS: This was a retrospective propensity score (PS)-matched study from a national cohort of, predominantly male, veterans diagnosed with diabetes without prior cardiovascular disease (from fiscal years 2003-2015), who were initiated on a statin. We created PS to match strict (mean LDL-C during follow-up ≤ 70 mg/dL) versus lenient (mean LDL-C during follow up > 70-100 mg/dL) using 65 baseline characteristics including comorbidities, risk scores, medication classes usage, vital signs, and laboratory data. Outcomes included MACE, diabetes progression, microvascular diabetes complications, and total mortality. RESULTS: From 80,110 eligible patients, we PS-matched 21,294 pairs of statin initiators with strict or lenient LDL-C lowering. The mean (SD) age was 64 (9.5) years and mean (SD) duration of follow-up was 6 (3) years. MACE was similar in the PS-matched groups [6.1% in strict versus 5.8% in lenient; odds ratio (OR): 1.06; 95% confidence interval (95% CI) 0.98-1.15, P = 0.17]. Diabetes progression was higher among the strict vs lenient group (66.7% in strict versus 64.1% in lenient; OR 1.12; 95% CI 1.08-1.17, P < 0.001). There was no difference in microvascular diabetes complications (22.3% in strict versus 21.9% in lenient; OR 1.02; 95% CI 0.98-1.07, P = 0.31) and no difference in total mortality (14.6% in strict versus 15% in lenient; OR 0.97; 95% CI 0.92-1.02, P = 0.20). CONCLUSION: Strict compared with lenient lowering of LDL-C with statins in men with diabetes without preexisting ASCVD did not decrease the risk of MACE but was associated with an increased diabetes progression. Clinicians should monitor their patients for diabetes progression upon escalating statins to achieve LDL-C levels ≤ 70 mg/dL.

Learning climate and work engagement in clinical residents: The relationship with human self-determination / Clima de aprendizaje y enganche al trabajo del residente clínico: relación con la autodeterminación humana

Introduction: The learning climate is a factor associated with the clinical resident's engagement in work activities and the improvement of students' well-being in the workplace through their self-determination during clinical rotation. Objective: To determine the relationship between the learning climate measured with the D-RECT 35 scale and residents' self-determination and commitment to work using the UWES 17 scale. Materials and methods: We conducted a cross-sectional correlational study with residents of surgical medical specialties in clinical rotation at the practice site and who completed the measurement questionnaires. Results: We evaluated 188 residents of clinical specialties. The median of the results in the learning climate scale was 3.9/5.0; in the self-determination scale, 4.86/7.0, and in the job engagement scale, 5.0/6.0. The learning climate was considered adequate and a positive relationship was found with self-determination and the residents' attachment to their activities; these correlations were statistically significant. Conclusions: Adequate learning climates are positively related to the ability to engage in work activities and the self-determination of clinical residents as they favor collaborative work and access to supervision generating greater autonomy and more enthusiasm and dedication to assigned activities. This can drive improvements in educational programs in clinical departments and translate into safer patient care.

Further studies are required that compare these effects with other methodologies for teaching in the classroom and the workplace.

Ichthyosis: case report in a Colombian man with genetic alterations in ABCA12 and HRNR genes.

BACKGROUND: Ichthyosis is a heterogeneous group of diseases caused by genetic disorders related to skin formation. They are characterized by generalized dry skin, scaling, hyperkeratosis and frequently associated with erythroderma. Among its different types, harlequin ichthyosis (HI) stands out due to its severity. HI is caused by mutations in the ABCA12 gene, which encodes essential proteins in epidermal lipid transport, and it helps maintain the homeostasis of the stratum corneum of the epidermis. However, due to the wide spectrum of genetic alterations that can cause ichthyosis, holistic medical care, and genetic studies are required to improve the diagnosis and outcomes of these diseases. CASE PRESENTATION: Here, we presented the case of a 19 years old male patient who was a premature infant and exhibited clinical features consistent with HI, including bright yellow hyperkeratotic plates with erythematous fissures that covered his entire body like a collodion baby. Currently, he exhibited erythroderma, photosensitivity, ectropion, auricular pavilion alterations, and musculoskeletal disorders, such as equinovarus feet, fingers, hands, and hypoplastic feet with contractures in flexion and marked difficulty in fine motor skills. In addition, he presented dyschromatopsia, Achilles reflex hyporeflexia, slight speech, dental alteration and deficient cognitive performance. After the genetic sequencing, variants were found in ABCA12 and HRNR which are related to several skin diseases, including ichthyosis. CONCLUSIONS: Although in clinical practice, ichthyosis is a common entity, a severe type of ichthyosis is presented, highlighting the importance of appropriate genetic diagnosis, given the broad spectrum of genetic alterations with similar phenotypic and clinical characteristics. These pathologies must be known to guarantee initial support measures to prevent complications and offer multidisciplinary management to those patients.

Risk of Eating Disorders and Use of Social Networks in Female Gym-Goers in the City of Medellín, Colombia. / Riesgo de trastorno de la conducta alimentaria y uso de redes sociales en usuarias de gimnasios de la ciudad de Medellín, Colombia.

INTRODUCTION: There are not many studies on prevalence and factors (use of social networks, for example) associated with eating disorders (ED) in Colombia. These types of studies in regular female gym-goers are of particular interest. METHODS: The objective was to analyse the relationship between the risk of EDs and the use of social networks in 337 women between the ages of 15 and 30 who had been regularly going to the gym in the city of Medellín for four months or more. The type of study was quantitative, descriptive and cross-sectional. RESULTS: A total of 143 (47.5%) cases with a risk of EDs were identified. Statistically significant associations were found between the risk of eating disorders and some aspects of the use of social networks. DISCUSSION: The possible association between ED, the use of social networks and certain personality characteristics and sociocultural beauty stereotypes are discussed. CONCLUSIONS: The findings point to an association between the use of social networks as a way to achieve self-image approval, abnormal eating attitudes and body satisfaction. This behaviour, added to other vulnerability factors, may increase the risk for the initiation or maintenance of an ED, particularly in the population using gyms and physical conditioning centres.

LINAGLIPTIN-INDUCED PANCREATITIS.

OBJECTIVE: To report a case of linagliptin-induced acute pancreatitis and remind clinicians about risks with incretin-based drugs. Patients at risk for pancreatitis should be switched to another type of hypoglycemic treatment. METHODS: We present the case of a 74-year-old Latina who presented to the emergency department with sudden onset of epigastric pain radiating to her back. Medical history, physical exam, laboratory tests, and medical images were compatible with acute pancreatitis. Upon further investigation, common causes for her pathology were excluded. Ten weeks prior to presentation she had changed her medications for diabetes mellitus type 2 to linagliptin. RESULTS: Using the Naranjo algorithm of adverse drug reactions, we concluded that linagliptin was the most likely culprit. CONCLUSION: Incretin-based drugs, including dipeptidyl peptidase-4 inhibitors and glucagon-like peptide-1 receptor agonists, have been shown to be relatively safe for the management of type 2 diabetes mellitus. Since their introduction to the market, conflicting data regarding pancreatic side effects have been published, including a small risk of developing acute pancreatitis with dipeptidyl peptidase-4 inhibitors like sitagliptin and saxagliptin. To date there has been only 1 case report associating linagliptin with acute pancreatitis in the English medical literature. Ours is the first case report in the United States associating linagliptin with acute pancreatitis. It is worth warning both patients and prescribers about this serious adverse effect, as it might affect the choice of antiglycemic agent.

Building bridges between medicine and the humanities: The role of scaffolds and articulation in surgical learning / Construcción de puentes entre la medicina y las humanidades: papel del soporte y la articulación en el aprendizaje en cirugía

Introduction: Learning about medicine from the humanities is a complex process that requires pedagogical strategies to avoid fragmentation and the paradox of transference. Instructional design in surgical education for these purposes is limited. Objective: To present the results of an educational strategy for the integration of surgery and the medical humanities based on the theoretical perspectives of the cognitive apprenticeship model and to assess its association with the students' perceptions of learning. Materials and methods: An instructional design was developed for the teaching of clinical conditions through the medical humanities. Students' perceptions of teachers' support and articulation for the integration of both disciplines, as well as students' self-perceptions of learning, were evaluated using validated questionnaires. Linear regression models were used to test the proposed association. Results: A total of 216 students was included in the analysis. High scores were obtained for each variable. The increase of one unit of teacher support and articulation for the integration of both disciplines was associated with an increase in student perception of learning (b) of 0.45 (CI 95% 0.30-0.60) and 0.40 (CI 95% 0.25 -0.55) (R2=0.64, p<0.001), respectively. Conclusions: Educational strategies focused on the techniques of support and articulation with the aim of integrating the medical humanities and surgery, demonstrated positive associations with students' perceptions of learning. Further studies are needed to evaluate the effects of these interventions on memory and long-term learning.

Introducción.
