El uso de entornos digitales en línea en la Universidad Jorge Tadeo Lozano ha permitido implementar una base de preguntas con retroa- limentación para apoyar al estudiante en el pro­ceso de aprendizaje en la asignatura Pensa­miento Matemático. Se desarrolló un proyecto de innovación pedagógica en dos semestres aca­démicos, con el fin de observar si el uso de una base de preguntas con retroalimentación en línea mejora el proceso de apropiación de los con­ceptos matemáticos de los estudiantes. Las pre­guntas que conformaron la base se diseñaron siguiendo indicaciones sobre elaboración de pre­guntas de múltiples opciones con única res­puesta; se utilizaron exámenes modelo con los temas vistos en cada uno de los tres momentos en que se divide un periodo académico de la Universidad; dichas evaluaciones formativas fueron puestas a disposición de los estudiantes dos semanas antes de cada evaluación. Debido al carácter del examen -en línea-, con múltiples in­tentos y accediendo desde cualquier dispositivo, el estudiante podía preparar sus evaluaciones con mayor autonomía y al ritmo que él estable­ciera. Se realizaron encuestas, entrevistas y gru­pos focales para identificar algunas característi­cas cualitativas que han permitido realizar ajustes y mejoras a la base de preguntas. Los da­tos obtenidos de cada modelo de examen y los resultados de los estudiantes durante los semes­tres fueron analizados estadísticamente. Los re­sultados, tanto cualitativos como cuantitativos, indican que en general, sí hay mejora en el de­sempeño y apropiación de los conceptos mate­máticos en aquellos estudiantes que acceden a los exámenes en línea frente a aquellos que no los usan.

Aim: To validate a novel equation to estimate weight from mid‐upper arm circumference (MUAC) among children with cerebral palsy (CP) in rural Bangladesh. Method: Children with CP aged 2 to 18 years registered in the Bangladesh CP Register were randomly selected. Data on sociodemographics, Gross Motor Function Classification System level, and anthropometric measurements were extracted. Bland–Altman plots with a 95% agreement limit and Lin's concordance correlation coefficient with 95% confidence intervals (CI) were reported to measure agreement between observed and estimated weight. Percentage error was used to determinate the method's accuracy. Results: There were 497 participants with a mean age at assessment of 9 years (SD 4 years 11 months) (47.7% female). Lin's concordance correlation coefficient between the observed and estimated weights was 0.90 (95% CI 0.89–0.92). Bland–Altman plots showed a reasonable accuracy of the equation in the study cohort. The mean percentage error of the equation was 5.04%. The average difference between observed and estimated weights was −1.02 kg (SD 5.1). The differences between observed and estimated weights were significantly greater among children with weight‐for‐age, height‐for‐age, or BMI‐for‐age z‐scores less than or equal to −4. Interpretation: It is possible to predict the weight of children with CP from MUAC with sufficient accuracy. The equation can be used for populations in low‐resources and low‐ and middle‐income countries. What this paper adds: The equations predict the weight of children with cerebral palsy from their mid‐upper arm circumference reasonably accurately.The difference between observed and estimated weights ranged between 0 kg and ± 5 kg in 81.5% of children.Sex and Gross Motor Function Classification System level did not affect the accuracy of the equations.The equations were less accurate for estimating the weight of severely undernourished children.

Conventional treatment that focuses on its etiological factors continues to be the gold standard; however, 30% of ulcers do not heal with this treatment; thus, it has been seen that the use of growth factor can be used as an adjuvant for this pathology. A literature review was carried out to evaluate the evidence from systematic reviews, meta-analyses, case studies, and quantitative studies that respond to the objective of this analysis review in the different databases with specific inclusion criteria with publications between 2002 and 2022, initially finding the topical application of the factor and later, more recently, the intralesional and perilesional application, the latter being an alternative treatment for this type of pathology and generating some recommendations for using the Factor.Keywords: chronic venous fibroblast dysfunctions, recombinant human epidermal growth factor, rhEGF, intralesional, perilesional, fibroblast dysfunctions

Teniendo como guía los resultados del Proyecto CONARBUS UN.-CIIQ2 (Conservación, Arborización y Uso Sostenido del Suelo) sobre Extensión Agroforestal. Experiencias publicadas por el CIAT (Centro Internacional de Agricultura Tropical) y utilizando una reciente investigación sobre la Extensión en la Universidad Nacional de Colombia. Se analizan los aportes de la INVESTIGACION PARTICIPATIVA como un conjunto de métodos de interacción con la comunidad campesina, para el desarrollo sostenido. La INVESTIGACION PARTICIPATIVA se define y se enumeran sus aportes, sustentados uno a uno en experiencias obtenidas y conocidas, resaltándose entre otros, los siguientes: Los conocimientos y experiencias del agricultor se tienen en cuenta, la tecnología escogida se adopta fácilmente, hay capacitación de agricultor a agricultor. Los fracasos tecnológicos se reducen, los costos de la investigación disminuyen, lo programado verticalmente por el investigador cambia o se ajusta o se refina, la autogestión puede promoverse y contribuye a solidificar o revivir las prácticas solidarias de organización social. Si no se remueven los factores negativos estructurales (como, acceso a tierra) y económicos, que condicionan la pobreza rural, los aportes de la INVESTIGACION PAATICIPATIVA serán infructuosos.

Se analiza la importancia de la Amazonía como reservaría de recursos genéticos vegetales, particularmente desde el punto de vista agroforestal. Se enumeran especies nativas potencialmente útiles como frutas, nueces, fuentes de aceite o de madera, con base en el conocimiento generado por los indígenas.

De la CUENCA AMAZONICA que tiene una extensión de 725.014.300 hectáreas, Colombia participa con 5.5% , es decir con 39.875.334 hectáreas. Así mismo dicha área es el 34.90%del total de Colombia y constituye la región naturalmás extensa del país. La Amazonía Colombiana está ubicada en la cabecera de varios de los afluentes más caudalosos del gran río Amazonas, la cuenca hidrográfica más amplia del mundo y por lo tanto, es de interés para la conservación delas partes bajas. Geográficamente comprende los Departamentos del Caquetá, Putumayo, Vaupés, Amazonas y la división de aguas de Guaviare y Guainía. La Amazonía intervenida con base el cálculos de 1980, era el 10% del área o sea 3.987.533 hectáreas. Alrededor del 80% dela superficie deforestada hasta 1980 en la Amazonía ha sido dedicada a pastizales.

Abstract Objective To establish the relationship between production of glutathione and the therapeutic response to amodiaquine (AQ) monotherapy in Plasmodium falciparum non-complicated malaria patients. Methodology Therapeutic response to AQ was evaluated in 32 patients with falciparum malaria in two townships of Antioquia, Colombia, and followed-up for 28 days. For every patient, total glutathione and enzymatic activity (glutathione reductase, GR, and γ-glutamylcysteine synthetase, γ-GCS) were determined in parasitized erythrocytes, non-infected erythrocytes and free parasites, on the starting day (day zero, before ingestion of AQ) and on the day of failure (in case of occurrence). Results There was found an AQ failure of 31.25%. Independent of the therapeutic response, on the starting day and on the day of failure, lower total glutathione concentration and higher GR activities in parasitized erythrocytes were found, compared with non-infected erythrocytes (p < 0.003). In addition, only on the day of failure, γ-GCS activity of parasitized erythrocytes was higher, compared with that of healthy erythrocytes (p = 0.01). Parasitized and non-parasitized erythrocytes in therapeutic failure patients (TF) had higher total glutathione on the starting day compared with those of adequate clinical response (ACR) (p < 0.02). Parasitized erythrocytes of TF patients showed lower total glutathione on the failure day, compared with starting day (p = 0.017). No differences was seen in the GR and γ-GCS activities by compartment, neither between the two therapeutic response groups nor between the two treatment days. Conclusion This study is a first approach to explaining P. falciparum therapeutic failure in humans through differences in glutathione metabolism in TF and ACR patients. These results suggest a role for glutathione in the therapeutic failure to antimalarials.

El manejo más eficiente y económico del complejo fltosanitario (Sogata - Hoja Blanca) está basado en el uso de variedades resistentes tanto al insecto como al virus (Pineda y Jennings 1985). Existen variedades de arroz resistentes al insecto y al virus de la hoja blanca como IRAT-124 e IRAT-121, pero hay variedades resistentes al insecto y susceptibles al virus como Clca-8 y viceversa como Colombla-1, y susceptibles tanto al uno como al otro como Blue-bonnet-50 (Y. de Galvls et. al. 1985). La enfermedad hoja blanca es una enfermedad ciclica; las epidemias duran varios años, seguidas por periodos más largos libres de la enfermedad (Pineda y Jennings 1985) y estas variaciones están relacionadas con cambios en el número de insectos vectores (McGulre et al. citados por Gálvez 1974).

The energy dispatch process in Colombia is carried out in four different stages. Electrical and reliability constraints are added at each stage. One of the most important characteristics of the dispatch process is the inclusion of a balanced risk policy. The dispatch must be calculated so that the expected relative load sheddings in the different sub-areas of the system are minimized and equalized. This paper presents a lineal optimization model that solves the dispatch problem in one single stage and incorporates the balanced risk policy mentioned above. [ABSTRACT FROM AUTHOR]

Background: Lip volumization and perioral rejuvenation with hyaluronic-acid (HA) based dermal fillers are generating increasing interest and demand. However, this topic is still having many unmet needs nowadays. This document aimed to provide tips and recommendations that may help clinicians to achieve optimal and more predictable aesthetic outcomes., Methods: A multidisciplinary group of aesthetic medicine doctors from Spain and Portugal reviewed the tools used for assessing the patient and aesthetic outcomes, as well as the different techniques and products used in lips/perioral rejuvenation., Results: The consensus panel provided specific recommendations focusing on the basic information to collect before performing the aesthetic procedure; comprehensive approach to lips/perioral region rejuvenation; clinical and aesthetic assessment tools; product and technique selection; patient profile and needs; and safety issues (complications/adverse-events)., Conclusions: The rapid evolution of techniques and tools for assessing the patient and aesthetic outcomes, as well as the development of new HA-based fillers makes it necessary to update the clinical recommendations that guide the daily practice of clinicians, particularly those who have less experience with these procedures. This document addressed relevant subjects related to lip/perioral-region rejuvenation to perform the correct procedure, with the appropriate HA-based, on the right patient; to help specialists to obtain optimal and predictable aesthetic outcomes., (© 2024 The Authors.

Introduction. During childhood, children may experience some degree of difficulty eating. A tool (PediEAT) has been developed in the United States and is available to assess pediatric eating and to identify problematic symptoms. Objective. To obtain an Argentine version that is transculturally adapted, culturally adequate, and semantically equivalent to the original version. Population and methods. A self-administered version of the PediEAT was used and completed by families and/or caregivers of children aged 6 months to 7 years. In the first phase, content validity was assessed by a group of experts. This was followed by a pre-test phase with families using cognitive interviews to test word and phrase comprehension. The necessary changes were made to obtain a version adapted to the context. Results. The tool's content validity was assessed by a group of 8 experts; as a result, 36 of the 80 items were changed. During the pre-test phase, cognitive interviews were conducted with 18 caregivers; 11 items were changed to improve comprehension by the Argentine population. The Argentine version was approved by the original authors. Conclusions. The Argentine version of the PediEAT tool is linguistically equivalent to the original version, and this allows its use to screen for feeding problems in children., (Sociedad Argentina de Pediatría.)

Background and Objective: Prostate-specific antigen (PSA) remains a critical marker for prostate cancer (PCa) detection and monitoring. Recognising historical variability in PSA assays and the evolution of assay technology and calibration, this study aims to reassess interassay variability using the latest generation of five assays in a contemporary cohort of men undergoing prostate biopsy., Methods: Five different commercially available PSA assays were tested in a blood sample of 76 men before undergoing a prostate biopsy. Total PSA (tPSA) and free-to-total PSA ratio (%fPSA) were compared across assays, using Roche (Basel, Switzerland) as the benchmark, and correlated with biopsy outcome to analyse the impact on PCa diagnosis. The statistical analysis included Passing-Bablok regression and Bland-Altman plots, with a p value threshold of <0.05 for significance., Key Findings and Limitations: Among the 76 men, 28 (36.8%) were diagnosed with significant PCa (defined as International Society of Urological Pathology grade ≥2). A high correlation was observed between tPSA and %fPSA values among the different PSA assays tested ( r 2  ≥ 0.9). The Passing-Bablok analysis showed that tPSA results varied substantially among the assays, with slopes ranging between 0.78 and 1.04. Compared with the tPSA of Roche, tPSA values were on average 20.7% lower by Beckman (Oststeinbeck, Germany), 15.2% lower by Abbott (Chicago, IL, USA), 6.1% lower by Diasorin (Saluggia, Italy), and 9.6% higher by Brahms (Hennigsdorf, Germany; p  < 0.001 for all). The %fPSA values by Abbott and Brahms were higher at 15.7% and 10.6%, respectively ( p  < 0.001), while the Beckman and Diasorin values had minimal differences of -0.3% and 2.3%, respectively ( p  > 0.05). The variability across assays would have resulted in discrepancies in both the sensitivity and the specificity for tPSA and %fPSA by at least 14%, depending on the cut-offs applied., Conclusions and Clinical Implications: Despite the use of the latest PSA assays, relevant variability of tPSA and %fPSA results can be observed among different assays. There is an urgent need for standardised calibration methods and greater awareness among practitioners concerning interassay variability. Clinicians should acknowledge that clinically relevant thresholds may depend on the specific PSA assay and that ideally the same assay is applied over time for better clinical decision-making., Patient Summary: Prostate-specific antigen (PSA) is a critical marker for prostate cancer (PCa) detection and monitoring. However, significant variations were observed in the results of the latest PSA assays. Thus, standardised calibration methods and greater awareness among practitioners concerning interassay variability are needed., (© 2024 The Author(s).)

Background: This study aims to compare the cyclic fatigue resistance (CFR) of the Reciproc Blue and WaveOne Gold instruments under a dynamic cyclical fatigue test., Material and Methods: 210 Reciproc Blue "R25" and WaveOne Gold "primary" files were assigned into 7 groups (n =15) for each brand. Groups G: Files were not exposed to NaOCl or sterilization. Groups A and D: files were immersed for 3 minutes in NaOCl 1 and 3 times, respectively. Groups B and E: Files were autoclaved 1 and 3 times, respectively. Groups C and F: files were exposed to both, NaOCl immersion and autoclaving 1 and 3 times, respectively. Subsequently, files underwent a dynamic CFR test. The chemical composition of the files' surface from Group G was analysed by energy-dispersive X-ray spectroscopy (EDS). Cyclic fatigue resistance time was statistically analysed using 1-way and 2-way analyses of variance (ANOVA) and T-test. A p -value ≤0,05 was set to be statistically significant., Results: There was a significantly higher CFR of RB files than WOG in groups A, B, C, D and G ( p <0.05). WOG files were superior to RB in group E ( p >0.05). There were no statistically significant differences between files in group F ( p >0.05). RB files from groups B, C, D, E and F had significantly lower resistance than new ones (Group G) ( p <0.05). WaveOne Gold files exposed to 5 % NaOCl immersion in combination with sterilization cycles (Groups C and F) had significantly lower CFR than new ones ( p <0.05). Reciproc Blue and WaveOne Gold NiTi alloys differed in atomic wt % of carbon, oxygen, nickel and titanium., Conclusions: The Reciproc Blue files outperformed the WaveOne Gold files in terms of CFR. The Reciproc Blue files were more vulnerable to the cycles of NaOCl immersion or autoclave sterilisation. The combined autoclaving and NaOCl cycles had the most significant impact on the mechanical properties of both files.

Background and Objective: The use of robotic surgery for managing upper tract urothelial carcinoma (UTUC) has increased significantly over the years. Minimally invasive techniques (MIS) are now used for approximately half of all robot-assisted laparoscopic nephroureterectomy (RAL-NU) performed in the USA. However, there are currently no specific management guidelines that recommend the use of a robotic approach, and the available literature on this topic is limited. For this reason, we reviewed the history and current literature regarding this technique., Methods: We searched Web of Science and PubMed for articles between 1934 to 2023 using 20 different search terms and combinations. We restricted our selection to only publications in English language., Key Content and Findings: Comparative retrospective studies between techniques [open nephroureterectomy (ONU), laparoscopic nephroureterectomy (LNU), and RAL-NU] and case series of surgical groups, mostly at short- and mid-term follow-up, were included., Conclusions: Robotic surgery for UTUC is on the rise and is predicted to become the preferred method for nephroureterectomy. A comparison of RAL-NU to LNU and ONU shows several advantages, including less blood loss, pain, and hospital stay, as well as a quicker recovery time. The safety and effectiveness of robotic surgery for lymphadenectomy also supports its use in RAL-NU. As more medical facilities adopt the technique and further studies support its benefits, it is likely that robotic surgery will become the preferred method for NU., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://tau.amegroups.com/article/view/10.21037/tau-23-73/coif).

Background: The introduction of Wolbachia (wMel strain) into Aedes aegypti mosquitoes reduces their capacity to transmit dengue and other arboviruses. Randomised and non-randomised studies in multiple countries have shown significant reductions in dengue incidence following field releases of wMel-infected Ae. aegypti. We report the public health outcomes from phased, large-scale releases of wMel-Ae. aegypti mosquitoes throughout three contiguous cities in the Aburrá Valley, Colombia., Methodology/principal Findings: Following pilot releases in 2015-2016, staged city-wide wMel-Ae. aegypti deployments were undertaken in the cities of Bello, Medellín and Itagüí (3.3 million people) between October 2016 and April 2022. The impact of the Wolbachia intervention on dengue incidence was evaluated in two parallel studies. A quasi-experimental study using interrupted time series analysis showed notified dengue case incidence was reduced by 95% in Bello and Medellín and 97% in Itagüí, following establishment of wMel at ≥60% prevalence, compared to the pre-intervention period and after adjusting for seasonal trends. A concurrent clinic-based case-control study with a test-negative design was unable to attain the target sample size of 63 enrolled virologically-confirmed dengue (VCD) cases between May 2019 and December 2021, consistent with low dengue incidence throughout the Aburrá Valley following wMel deployments. Nevertheless, VCD incidence was 45% lower (OR 0.55 [95% CI 0.25, 1.17]) and combined VCD/presumptive dengue incidence was 47% lower (OR 0.53 [95% CI 0.30, 0.93]) among participants resident in wMel-treated versus untreated neighbourhoods., Conclusions/significance: Stable introduction of wMel into local Ae. aegypti populations was associated with a significant and sustained reduction in dengue incidence across three Colombian cities. These results from the largest contiguous Wolbachia releases to-date demonstrate the real-world effectiveness of the method across large urban populations and, alongside previously published results, support the reproducibility of this effectiveness across different ecological settings., Trial Registration: NCT03631719., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Velez et al.

Objective: Despite the wide-spread adoption of robotic-assisted surgery (RAS), the cost-benefit implications for partial (PN) and radical nephrectomy (RN) versus laparoscopic surgery (Lap) is not well established. We sought to examine the trend of adoption and 1-year healthcare expenditure of PN and RN, and compare 1-year expenditures of RAS versus Lap for PN and RN., Patients and Methods: This cohort study used the Merative TM MarketScan® Databases between 2013 and 2020. A total of 5,353 patients with kidney cancer undergoing PN (2,980, 55.7%) or RN (2,373, 44.3%). We compared open-conversion, length of stay (LOS), index expenditure, 1-year healthcare expenditure and utilization, and missed work-days between RAS and Lap for PN and RN., Results: Adoption of PN increased overtime (47.0% to 55.8%), mainly driven by robotic PN increase. Among PN, RAS had lower open-conversion, shorter LOS and lower index expenditure than Lap. Among RN, RAS had shorter LOS, and similar open-conversion and index expenditures. During 1-year post-discharge, RAS had lower hospital outpatient visits (IRR = 0.92, 95% CI = 0.85, 0.99, p = 0.029) and office-based visits (IRR = 0.91, 95% CI = 0.86, 0.96, p = 0.002) for PN, translating to a 1-day less (95% CI = 0.25, 1.75, p = 0.008) missed from work for RAS. Following RN, RAS had lower 1-year readmission than Lap (O.R = 0.72, 95% CI = 0.55, 0.94, p = 0.018). RAS and Lap had comparable 1-year post-discharge expenditures for both PN (mean difference, MD = -$475, 95% CI = -$4362, $3412, p = 0.810) and RN (MD = -$4,204, 95% CI = -$13,837, $5430, p = 0.404)., Conclusion: At index surgery, RAS was associated with shorter LOS for both PN and RN, and lower open-conversion and expenditures for PN. RAS and Lap had comparable 1-year total expenditures, despite lower healthcare visits for RAS., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Extracellular vesicles (EVs)-including apoptotic bodies, microvesicles, and exosomes-are released by almost all cell types and contain molecular footprints from their cell of origin, including lipids, proteins, metabolites, RNA, and DNA. They have been successfully isolated from blood, urine, semen, and other body fluids. In this review, we discuss the current understanding of the predictive value of EVs in prostate and renal cancer. We also describe the findings supporting the use of EVs from liquid biopsies in stratifying high-risk prostate/kidney cancer and advanced disease, such as castration-resistant (CRPC) and neuroendocrine prostate cancer (NEPC) as well as metastatic renal cell carcinoma (RCC). Assays based on EVs isolated from urine and blood have the potential to serve as highly sensitive diagnostic studies as well as predictive measures of tumor recurrence in patients with prostate and renal cancers. Overall, we discuss the biogenesis, isolation, liquid-biopsy, and therapeutic applications of EVs in CRPC, NEPC, and RCC.

Background: Prediction of extracapsular extension (ECE) is essential to achieve a balance between oncologic resection and neural tissue preservation. Microultrasound (MUS) is an attractive alternative to multiparametric magnetic resonance imaging (mpMRI) in the staging scenario., Objective: To create a side-specific nomogram integrating clinicopathologic parameters and MUS findings to predict ipsilateral ECE and guide nerve sparing., Design Setting and Participants: Prospective data were collected from consecutive patients who underwent robotic-assisted radical prostatectomy from June 2021 to May 2022 and had preoperative MUS and mpMRI. A total of 391 patients and 612 lobes were included in the analysis., Outcome Measurements and Statistical Analysis: ECE on surgical pathology was the primary outcome. Multivariate regression analyses were carried out to identify predictors for ECE. The resultant multivariable model's performance was visualized using the receiver-operating characteristic curve. A nomogram was developed based on the coefficients of the logit function for the MUS-based model. A decision curve analysis (DCA) was performed to assess clinical utility., Results and Limitations: The areas under the receiver-operating characteristic curve (AUCs) of the MUS-based model were 81.4% and 80.9% (95% confidence interval [CI] 75.6, 84.6) after internal validation. The AUC of the mpMRI-model was also 80.9% (95% CI 77.2, 85.7). The DCA demonstrated the net clinical benefit of the MUS-based nomogram and its superiority compared with MUS and MRI alone for detecting ECE. Limitations of our study included its sample size and moderate inter-reader agreement., Conclusions: We developed a side-specific nomogram to predict ECE based on clinicopathologic variables and MUS findings. Its performance was comparable with that of a mpMRI-based model. External validation and prospective trials are required to corroborate our results., Patient Summary: The integration of clinical parameters and microultrasound can predict extracapsular extension with similar results to models based on magnetic resonance imaging findings. This can be useful for tailoring the preservation of nerves during surgery., (© 2022 The Authors.)

Objectives: To estimate typologies of Intimate Partner Violence against women in some Latin-American countries. Methods: Multistage sampling survey included women aged 15 to 49 ( n = 63,321). Latent class analysis was estimated, including psychological, physical, and sexual violence and control. Results: The three-class model had a better fit. 1) The high-level IPV class (23%) comprised those suffering high levels of violence. They had higher education and wealth index, lived in urban settings, and their husbands used alcohol more. 2) The middle-level IPV class (45%) suffered high levels of control but low levels of other violence. They justified IPV more than other classes and this group had a high proportion of women without education. 3) Women in the non-IPV class (32%) did not report IPV. Conclusion: Three typologies of IPV were found: high-level, middle-level, and non-IPV. Policies should create screening, early prevention strategies, and programs based on these typologies. The high-level IPV group can benefit from intense legal and mental health interventions, including alcohol reduction and women's empowerment. The middle-level IPV group could benefit from interventions to reduce violence justification and increase women's education., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Restrepo, Montoya and Zuluaga.)

Water crises in Latin America are more a consequence of poor management than resource scarcity. Addressing water management issues through better coordination, identification of problems and solutions, and agreement on common objectives to operationalize integrated water resources management (IWRM) could greatly improve water governance in the region. Composite indices have great potential to help overcome capacity and information challenges while supporting better IWRM. We applied one such index, the Freshwater Health Index (FHI) in three river basins in Latin America (Alto Mayo, Perú; Bogotá, Colombia; and Guandu, Brazil) to assess freshwater ecosystem vitality, ecosystem services, and the water governance system in place. The approach included convening management agencies, water utilities, planning authorities, local NGOs and industries, community groups and researchers to co-implement the FHI. The results provide detailed information on the ecological integrity of each basin and the sustainability of the ecosystem services being provided. All three basins show very low scores for governance and stakeholder engagement, thus improving both in the region should be a priority. The results also shed light on how the FHI framework can help inform decision-making to improve IWRM implementation by facilitating stakeholder engagement while contributing to coordination, identification of problems and solutions as well as agreement on common objectives. Because implementation of IWRM is part of the solution for the United Nations Sustainable Development Goal (SDG) 6.5 ("By 2030, implement IWRM at all levels, including through transboundary cooperation as appropriate"), our case studies can serve as examples to other Latin American countries to achieve SDG 6.5., (© 2021.

Three-dimensional printing (3DP) has recently gained importance in the medical industry, especially in surgical specialties. It uses different techniques and materials based on patients' needs, which allows bioprofessionals to design and develop unique pieces using medical imaging provided by computed tomography (CT) and magnetic resonance imaging (MRI). Therefore, the Department of Biology and Medicine and the Department of Physics and Engineering, at the Bioastronautics and Space Mechatronics Research Group, have managed and supervised an international cooperation study, in order to present a general review of the innovative surgical applications, focused on anatomical systems, such as the nervous and craniofacial system, cardiovascular system, digestive system, genitourinary system, and musculoskeletal system. Finally, the integration with augmented, mixed, virtual reality is analyzed to show the advantages of personalized treatments, taking into account the improvements for preoperative, intraoperative planning, and medical training. Also, this article explores the creation of devices and tools for space surgery to get better outcomes under changing gravity conditions., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 José Cornejo et al.)

The COVID-19 pandemic is pronounced as a turning point in our professional health practice, from which new opportunities will arise with which we must promote the rights of children and people with disabilities., (Universidad Nacional de Córdoba)

Q-tip test offers a simple approach for identifying urethral hypermobility. Considering surgical treatment, stress urinary incontinence (SUI) must be classified and the contribution of intrinsic sphincter deficiency (ISD) and/or urethral hypermobility must be determine. We believe there's a correlation between abdominal leak point pressure (ALPP) and urethral mobility degree, and the aim of this study is to explore it using Q-tip. We conducted a prospective study, between years 2014 and 2016. Females over 18 years presenting with signs and symptoms of SUI according to the 2002 ICS Standardization of Terminology were included. Assessment was made with the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), the Q-tip test and invasive urodynamics. Urethral mobility (UM) and ALPP were analyzed. We built two composite variables based on reported risk factors for ISD, defined as composite variable A (equal to a Q-tip test < 30° AND ICIQ-SF ≥ 10 points) and composite variable B (equal to low urethral mobility AND/OR hypoestrogenism AND/OR history of radiotherapy AND/OR previous pelvic surgery). Correlation analyzes were made according to the type of variable. A total of 221 patients were included. Incontinence was rated as moderate and severe by 65.3% and 6.8%, respectively. The analysis showed a 61.75%, 51.61% and 70.6% agreement between ALPP and UM, ALPP and composite variable A and ALPP and composite variable B respectively. Correlation and concordances were low (r = 0.155, r&#95;s = - 0.053 and r&#95;s = - 0.008), (rho&#95;c = 0.036, k = 0.116 and k = 0.016). Neither the degree of UM, nor the composite variables, correlate or agree with urethral function tests in UDS, suggesting that the ALPP cannot be predicted using the Q-tip test or the ICIQ-SF for classifying patients with SUI.

Introduction: In the context of the COVID-19 pandemic, WHO published considerations regarding people with disabilities. The aim of this work was to know if these considerations can be fulfilled and if there are differences in their fulfillment between age groups., Method: Descriptive study aimed at people with disabilities in Argentina. A survey was conducted about the four WHO recommendations for this population in online mode, between the 28th and 39th days of preventive and compulsory social isolation. Statistical analysis was according to the nature of the variables, X2 with Fisher's correction was used to determine the differences between groups., Results: 309 surveys were collected from 18 provinces of Argentina. 230(74.4%[69.1-79.1]) were answered by caregivers and 79(25.5%[20.7-30.7]) by people with disabilities. Persons with disabilities were 138(44.7%[39.0-50.4]) children and adolescents and 171(55.3%[49.5-60.9]) adults and older adults. People with disabilities were able to comply with the WHO recommendations regarding reducing exposure to COVID-19 and to be prepared in case of contracting it. There were difficulties in the number of caregivers needed, since 266(66.6%[61.0-71.8]) have this possibility, and difficulties in 55(32.1%[25.1-39.6]) adults and older adults that do not carry out educational-therapeutic activities. There are feelings of anxiety, distress, or depression in people with disabilities and their caregivers., Conclusion: In Argentina, it is possible to comply with the WHO recommendations to avoid exposure to the virus and to be prepared in case of infection. Challenges remain to be solved in terms of accompanying people with disabilities in their physical and mental health., (Universidad Nacional de Córdoba)
