RESUMEN
BACKGROUND: A telehealth mental health programme was designed at the LivingLab of the Faculty of Medicine of the Universidad de Antioquia [University of Antioquia]. OBJECTIVES: To describe the development and operation of the programme and evaluate the satisfaction of the patients treated during the COVID-19 pandemic in 2020 and 2021. METHODS: Descriptive study that details the development of the programme. Data were extracted from medical records to describe the patients who were treated. A satisfaction scale was applied to a random sample and the data were summarised with descriptive statistics. RESULTS: In March 2020 and August 2021, 10,229 patients were treated, with 20,276 treated by telepsychology and 4,164 by psychiatry, 1,808 by telepsychiatry and 2,356 by tele-expertise, with a total of 6,312 visits. The most frequent diagnoses were depressive (36.8%), anxiety (12.0%), and psychotic (10.7%) disorders. Respondents were satisfied to the point that more than 93% would recommend it to another person. CONCLUSIONS: The LivingLab telehealth mental health programme allowed for the care of patients with mental health problems and disorders in Antioquia during the first two years of the COVID-19 pandemic, and there was a high degree of satisfaction among the beneficiaries. Therefore it could be adopted in mental health care.
RESUMEN
Objectives: Concept embeddings are low-dimensional vector representations of concepts such as MeSH:D009203 (Myocardial Infarction), whose similarity in the embedded vector space reflects their semantic similarity. Here, we test the hypothesis that non-biomedical concept synonym replacement can improve the quality of biomedical concepts embeddings. Materials and methods: We developed an approach that leverages WordNet to replace sets of synonyms with the most common representative of the synonym set. Results: We tested our approach on 1055 concept sets and found that, on average, the mean intra-cluster distance was reduced by 8% in the vector-space. Assuming that homophily of related concepts in the vector space is desirable, our approach tends to improve the quality of embeddings. Discussion and Conclusion: This pilot study shows that non-biomedical synonym replacement tends to improve the quality of embeddings of biomedical concepts using the Word2Vec algorithm. We have implemented our approach in a freely available Python package available at https://github.com/TheJacksonLaboratory/wn2vec.
RESUMEN
Transgender and gender diverse youth and young adults (TGDY) experience higher mental health morbidity, including self-harm, suicide ideation, and suicide attempts, as compared to cisgender peers. Support from family members is associated with improved mental health outcomes for TGDY. However, little is known about the process that caregivers who consider themselves supportive undergo and how caregiver-youth relationships evolve through a TGDY's gender journey. Through a reflexive thematic analysis of 14 interviews conducted with caregivers of TGDY from April-July 2022, we sought to understand how caregivers who considered themselves supportive of TGDY navigated shifting relationships with themselves, their children, and their communities. Applying theories of Ambiguous Loss and Thriving Through Relationships, findings coalesced around several themes including reflecting on change, re-negotiating interpersonal relationships, and educating through relationships. The gender journeys of TGDY required caregivers to navigate relationships with self (feeling loss and wrestling with worry for their child), negotiate relationships with others (disclosing to extended family and social networks), and educate themselves and others through relationships (connecting through personal narratives from other families, parents supporting parents, learning to advocate for their child). The process of caregivers learning to support their children was facilitated through profound intrapersonal and interpersonal reflection, connection, and community. Understanding this process is important to inform educational interventions and programs that help caregivers learn to support and advocate effectively for TGDY.
RESUMEN
Environmentally friendly polymers such as cellulose acetate (CA) and chitosan (CS) were used to obtain electrospun fibers for Cu2+, Pb2+, and Mo6+ capture. The solvents dichloromethane (DCM) and dimethylformamide (DMF) allowed the development of a surface area of 148 m2 g-1 for CA fibers and 113 m2 g-1 for cellulose acetate/chitosan (CA/CS) fibers. The fibers were characterized by IR-DRIFT, SEM, TEM, CO2 sorption isotherms at 273 K, Hg porosimetry, TGA, stress-strain tests, and XPS. The CA/CS fibers had a higher adsorption capacity than CA fibers without affecting their physicochemical properties. The capture capacity reached 102 mg g-1 for Cu2+, 49.3 mg g-1 for Pb2+, and 13.1 mg g-1 for Mo6+. Furthermore, optimal pH, adsorption times qt, and C0 were studied for the evaluation of kinetic models and adsorption isotherms. Finally, a proposal for adsorbate-adsorbent interactions is presented as a possible capture mechanism where, in the case of Mo6+, a computational study is presented. The results demonstrate the potential to evaluate the fibers in tailings wastewater from copper mining.

RESUMEN
The recent breakthroughs of Large Language Models (LLMs) in the context of natural language processing have opened the way to significant advances in protein research. Indeed, the relationships between human natural language and the "language of proteins" invite the application and adaptation of LLMs to protein modelling and design. Considering the impressive results of GPT-4 and other recently developed LLMs in processing, generating and translating human languages, we anticipate analogous results with the language of proteins. Indeed, protein language models have been already trained to accurately predict protein properties, generate novel functionally characterized proteins, achieving state-of-the-art results. In this paper we discuss the promises and the open challenges raised by this novel and exciting research area, and we propose our perspective on how LLMs will affect protein modeling and design.
RESUMEN
Las infecciones del sitio quirúrgico son una de las complicaciones más frecuentes a nivel mundial en lo referente a IAAS. Aumentan la morbimortalidad de los pacientes quirúrgicos, y representan un problema a nivel de la salud pública. Existen medidas profilácticas tanto preoperatorias como postoperatorias, que buscan disminuir la frecuencia de esta complicación postquirúrgica tan temida por los médicos. Además, existen factores de riesgo los cuales pueden como no ser modificables que incrementan la incidencia de estas infecciones. SE revisaron guías internacionales que buscan estandarizar las medidas más acordes en el preoperatorio que lleguen a disminuir la presencia de infecciones de sitio quirúrgico.
RESUMEN
Over the past two decades there have been major advances in the development of interventions promoting mental health and well-being in low- and middle-income countries (LMIC), including delivery of care by non-specialist providers, incorporation of mobile technologies and development of multilevel community-based interventions. Growing inequities in mental health have led to calls to adopt similar strategies in high-income countries (HIC), learning from LMIC. To overcome shared challenges, it is crucial for projects implementing these strategies in different global settings to learn from one another. Our objective was to examine cases in which mental health and well-being interventions originating in or conceived for LMIC were implemented in the USA. The cases included delivery of psychological interventions by non-specialists, HIV-related stigma reduction programmes, substance use mitigation strategies and interventions to promote parenting skills and family functioning. We summarise commonly used strategies, barriers, benefits and lessons learnt for the transfer of these innovative practices among LMIC and HIC. Common strategies included intervention delivery by non-specialists and use of digital modalities to facilitate training and increase reach. Common barriers included lack of reimbursement mechanisms for care delivered by non-specialists and resistance from professional societies. Despite US investigators' involvement in most of the original research in LMIC, only a few cases directly involved LMIC researchers in US implementation. In order to achieve greater equity in global mental health and well-being, more efforts and targeted funding are needed to develop best practices for global health reciprocal innovation and iterative learning in HIC and LMIC.

Abstract OBJECTIVE: To describe the experience with the readjustable sling Remeex® in patients with recurrent stress urinary incontinence as a treatment alternative. MATERIALS AND METHODS: Retrospective, observational, case series study carried out in a single center in the city of Medellin, Colombia, in patients attended at the Urogynaecology Unit of the Bolivarian University Clinic. Inclusion criteria: women over 18 years of age, with a diagnosis of recurrent urinary incontinence after one or more failed surgeries to correct urinary incontinence or with a diagnosis of intrinsic sphincter deficiency who underwent the readjustable sling procedure (Remeex Female Neomedic) between 2016 and 2019. RESULTS: Nineteen patients were evaluated with mean age 62 years (SD ± 9). The median follow-up was 19.4 months (RIQ 10-26.5). All patients had preoperative urodynamics that confirmed the diagnosis of stress urinary incontinence. All 19 patients had a diagnosis of moderate-severe-recurrent urinary incontinence, 4 with detrusor hypoactivity and 1 with intrinsic sphincter deficiency. Of the 19 patients, 10 underwent surgery for correction of concomitant pelvic organ prolapse, which were distributed as follows: 6 patients with anterior or posterior colporrhaphy, 3 colpocleisis and 1 sacrocolpopexy by laparotomy. CONCLUSIONS: The readjustable sling is a good option for women with previous anti-incontinence interventions with recurrence in whom improvement in the degree of incontinence in relation to the initial one was demonstrated, a benefit that was reflected in better quality of life.
RESUMEN
La colecistectomía laparoscópica es el estándar de oro para el tratamiento de la litiasis vesicular. El presente estudio tiene por objetivo difundir la experiencia de 10 años en colecistectomía laparoscópica del Hospital Municipal Los Pinos de La Paz, Bolivia. Se realizó la revisión de historias clínicas de pacientes internados y sometidos a colecistectomía laparoscópica de junio 2012 a julio 2022, la serie de casos estuvo compuesta por 1095 pacientes; 866 (79.3%) mujeres y 229 (20.7%) varones; el grupo etáreo con mayor casuística fue 31 a 40 años con 256 casos (23.3%), la edad promedio fue de 50,5 (10 a 81 años). La vía de ingreso de los pacientes fue por consulta externa 72.5% y emergencias 27.4%. El tiempo operatorio promedio fue de 85 min. (20 a 150 min.). El diagnostico de ingreso de mayor prevalencia fue la colecistitis crónica litiasica con 766 (69.9%). El factor de conversión a cirugía abierta fue la falta de identificación de estructuras anatómicas, con un índice de conversión de 6.9%. La estancia postoperatoria promedio fue de 3.5 días (1 a 6 días). Basado en los resultados obtenidos la colecistectomía laparoscópica demuestra ser aun el tratamiento seguro y efectivo en pacientes con colelitiasis.
Laparoscopic cholecystectomy is the Gold standard for the treatment of vesicular lithiasis. The present study aims to describe the experience in laparoscopic cholecystectomy of 10 years at Los Pinos Municipal Hospital in La Paz, Bolivia. A review of medical records of hospitalized patients undergoing laparoscopic cholecystectomy from June 2012 to July 2022 was carried out. Case series were 1095 patients; 866 (79.3%) female and 229 (20.7%) male; the age group with higher casuistry was 31 to 40 years (256 cases, 23.3%), the average age was 50.5 (10 to 81 years). The admission of patients was by outpatient 72.5% and emergency unit 27.4%. The average surgery time was 85 min. (20 to 150 min.). The highest prevalence diagnosis at admission was chronic lithiasic cholecystitis (766 cases, 69.9%). The conversion factor to open surgery was the anatomical structures identification difficulty, conversion rate of 6.9 %. The postoperative hospital stay average was 3.5 days (1 to 6 days). Based on the results obtained, laparoscopic cholecystectomy still proves to be the safe and effective treatment in patients with cholelithiasis.

RESUMEN
BACKGROUND: Substantial data from high-income countries support early interventions in the form of evidence-based Coordinated Specialty Care (CSC) for people experiencing First Episode Psychosis (FEP) to ameliorate symptoms and minimize disability. Chile is unique among Latin American countries in providing universal access to FEP services through a national FEP policy that mandates the identification of FEP individuals in primary care and guarantees delivery of community-based FEP treatments within a public health care system. Nonetheless, previous research has documented that FEP services currently provided at mental health clinics do not provide evidence-based approaches. This proposal aims to address this shortfall by first adapting OnTrackNY (OTNY), a CSC program currently being implemented across the USA, into OnTrackChile (OTCH), and then examine its effectiveness and implementation in Chile. METHODS: The Dynamic Adaptation Process will be used first to inform the adaptation and implementation of OTCH to the Chilean context. Then, a Hybrid Type 1 trial design will test its effectiveness and cost and evaluate its implementation using a cluster-randomized controlled trial (RCT) (N = 300 from 21 outpatient clinics). The OTCH program will be offered in half of these outpatient clinics to individuals ages 15-35. Usual care services will continue to be offered at the other clinics. Given the current COVID-19 pandemic, most research and intervention procedures will be conducted remotely. The study will engage participants over the course of 2 years, with assessments administered at enrollment, 12 months, and 24 months. Primary outcomes include implementation (fidelity, acceptability, and uptake) and service outcomes (person-centeredness, adherence, and retention). Secondary outcomes comprise participant-level outcomes such as symptoms, functioning, and recovery orientation. Over the course of the study, interviews and focus groups with stakeholders will be conducted to better understand the implementation of OTCH. DISCUSSION: Findings from this study will help determine the feasibility, effectiveness, and cost for delivering CSC services in Chile. Lessons learned about facilitators and barriers related to the implementation of the model could help inform the approach needed for these services to be further expanded throughout Latin America. TRIAL REGISTRATION: www. CLINICALTRIALS: gov NCT04247711 . Registered 30 January 2020. TRIAL STATUS: The OTCH trial is currently recruiting participants. Recruitment started on March 1, 2021, and is expected to be completed by December 1, 2022. This is the first version of this protocol (5/12/2021).

INTRODUCTION: Latinx children with communication disorders from birth to age 5 and their families are increasingly served in United States (US) educational and medical settings where longstanding structural barriers threaten their access to equitable assessment and intervention. However, little is known about providers' perceptions serving this highly diverse population as they relate to reducing disparities in care for communication disorders. METHODS: This exploratory qualitative study interviewed 24 speech-language pathologists (SLPs) and early intervention (EI)/early childhood special education (ECSE) developmental specialists serving young Latinx children with communication disorders to offer targeted recommendations toward improving equity. The semi-structured interview included questions regarding communication assessment, diagnostics/eligibility, intervention, interpretation, translation, and solutions to enhance EI/ECSE. Interviews were coded with content analysis using elements of grounded theory, and responses from SLPs in medical versus education settings and from EI/ECSE developmental specialists were compared. Data triangulation was used to validate themes. RESULTS: Analysis revealed the following themes related to provider challenges and resources: family factors, provider factors, cultural and linguistic differences, assessment approaches, eligibility determinations, translation and interpretation, and institutional factors. Few variations in themes between provider types (SLPs vs. EI/ECSE developmental specialists) and settings (medical vs. educational) were found. Providers also offered several policy and practice solutions. CONCLUSIONS: Findings suggest minimal advances in improving equity for young Latinx children with communication disorders over prior decades. Results also indicate that providers may benefit from reflecting on their cultures and biases as well as systemic racism within EI/ECSE.

RESUMEN
ABSTRACT Bacteria isolated from food contact surfaces, can transfer resistance factors when exposed to pressure exerted by inappropriate use of antimicrobial agents. This study aimed to evaluate bacterial resistance against antibiotics and disinfectants commonly used (NaOCl and CH3COOH) in bacteria isolated from food contact surfaces. Additionally, using PCR, the presence of tetracycline resistance genes was evaluated. Results showed that 47% of the isolates exhibit resistance against more than one antibiotic, being Tetracycline the antibiotic that most isolates were resistant to (35.3%). A PCR analysis found that the tet M gene is the most frequent of the genes tested. Likewise, it was evidenced that although NaOCl is effective as a surface disinfectant, Aerococcus urinae and Kocuria kristinae isolates could resist up to 10 min of exposure. Likewise, all isolates were resistant to CH3COOH, demonstrating the low inhibitory capacity of this disinfectant. Finally, the observed correlation between resistance to antibiotics and resistance to disinfectants is confirmed. An important factor that should be studied since the generalized use of disinfectants can increase the spectrum of antibiotic resistance.
RESUMEN Bacterias aisladas de superficies en contacto con alimentos pueden transferir factores de resistencia cuando se exponen a presiones ejercidas por el uso inadecuado de agentes antimicrobianos. En este estudio se evaluó la resistencia bacteriana frente a antibióticos y desinfectantes de uso común (NaOCl y CH3COOH) en bacterias aisladas de superficies en contacto con alimentos. Adicionalmente, mediante la PCR se evaluó la presencia de genes de resistencia a la Tetraciclina. Los resultados mostraron que el 47% de los aislados presentaron resistencia a más de un antibiótico, siendo la Tetraciclina al que la mayoría de los aislamientos fueron resistentes (35,3%). El análisis de PCR encontró que el gen tet M fue el más frecuente. Además, se evidenció que, si bien el NaOCl es efectivo como desinfectante de superficies, Aerococcus urinae y Kocuria kristinae pudieron resistir hasta 10 minutos de exposición. Igualmente, todos los aislados fueron resistentes a CH3COOH, demostrando la baja capacidad inhibitoria de este desinfectante. Finalmente, se confirma una correlación entre la resistencia a antibióticos y desinfectantes. Un factor importante que conviene estudiar ya que el uso generalizado de desinfectantes podría incrementar el espectro de resistencia a los antibióticos.

Os resultados mostraram que 47% dos isolados mostraram resistência a mais do que um antibiótico, sendo a Tetraciclina a que a maioria dos isolados era resistente (35,3%). A análise PCR constatou que o gene tet M era o mais frequente. Além disso, era evidente que, embora NaOCl seja eficaz como desinfectante de superficie, Aerococcus urinae e Kocuria kristinae foram capazes de resistir até l0 minutos de exposição. Da mesma forma, todos os isolados eram resistentes ao CH3COOH, demonstrando a baixa capacidade inibitória deste desinfectante. Finalmente, é confirmada uma correlação entre a resistência aos antibióticos e a resistência aos desinfectantes. Este é um factor importante que deve ser estudado uma vez que a utilização generalizada de desinfectantes poderia aumentar o espectro da resistência aos antibióticos.
