Introducción y objetivo: El cirujano plástico que realiza rinoplastia se enfrenta a pacientes con diferentes características según su etnia. Entre las estrategias implementadas para pacientes sometidos a rinoplastia se ha descrito el uso de isotretinoina para el manejo de pieles gruesas. Actualmente existen diferentes vacíos en la literatura sobre el beneficio y las complicaciones asociadas a este tipo de tratamiento en rinoplastia. El objetivo del presente trabajo es revisar la evidencia disponible en la literatura sobre los beneficios y riesgos derivados del uso de isotretinoina y rinoplastia Material y método: Desarrollamos una revisión del alcance del conocimiento en las diferentes bases de datos: Cochrane, PubMed, Embase, SAGE, Sciencie Direct, Taylor and Francis, utilizando los términos Mesh “Rhinoplasty AND Isotretinoin” para posteriormente evaluar los diferentes criterios de inclusión y exclusión que permitieron filtrar artículos evaluados en inglés y español. Resultados: Recogimos en total 2621 artículos publicados entre enero del 2005 y junio del 2022, de los cuales 13 cumplieron con los criterios establecidos por los investigadores para su análisis: 5 reportes de caso, 2 revisiones narrativas, 2 artículos tipo experimental, 1 consenso de expertos, 1 de casos y controles, 1 estudio multicéntrico y 1 revisión sistemática de la literatura. Conclusiones: La isotretinoina es un medicamento que, en diferentes artículos revisados, se demuestra seguro en su uso concomitante con procedimientos faciales como la rinoplastia y genera resultados favorables estéticos en paciente con nariz de piel gruesa en los 6 primeros meses de postoperatorio. Sin embargo, su uso debe ser analizado de manera individual puesto que puede llegar a producir efectos adversos tales como piel seca y adelgazamiento excesivo de la piel nasal. (AU)

Background and objective: Plastic surgeons who perform rhinoplasty face with patients with different characteristics depending on their ethnicity. Among the strategies implemented for these patients, the use of isotretinoin has been described for the management of thick skin. Currently, there are multiple gaps in the literature regarding the benefit and associated complications of this type of treatment in rhinoplasty. The objective of this study is to review the evidence available in the literature on the benefits and risks derived from the use of isotretinoin and rhinoplasty. Methods: A scoping review of the literature was developed on data base: PubMed Central (PMC), Cochrane, Sciencie Direct, Taylor and Francis Databases using Mesh terms “Rhinoplsaty AND Isotretinoin”. The articles were evaluated and classified to identify the available evidence in English and Spanish. Results: A review of 2621 articles published on different databases between January 2005 and June 2022 was performed, and 13 articles met the criteria established by the researchers for their analysis: 5 case reports, 2 narrative reviews, 2 controlled trials, 1 expert consensus, 1 case and control, 1 multicenter study, and 1 systematic review of the literature. Conclusions: Isotretinoin is a safe drug in concomitant use with facial procedures such as rhinoplasty and generates favorable aesthetic results in patients with a thick-skinned nose in the first 6 postoperative months. However, its use must be analyzed individually in every case since it can produce adverse effects such as dry skin and excessive thinning of the nasal skin. (AU)

Navigating the COVID-19 pandemic together: Discussions between persons with early-stage dementia and their adult children.

OBJECTIVES: Studies have separately examined the health impacts of the COVID-19 pandemic on persons with dementia and their caregivers. Less attention has been paid to the social and emotional impacts of the pandemic in this population or how these individuals are mutually coping with the pandemic. Guided by the social citizenship theory, this qualitative study sought to characterize how persons with dementia and their adult children are coping during this time with a focus on the strengths demonstrated by persons with dementia. METHODS: Participants were 43 dyads of individuals aged 55 and older with early-stage dementia and their adult children. Discussions between parent-child dyads were recorded. Using reflexive thematic analysis, themes related to social and emotional impacts of the pandemic and coping strategies were identified. RESULTS: Adult children shared with their parents how the pandemic resulted in reduced social engagement and challenging work arrangements. Dyads described how the pandemic positively impacted their relationship, allowing some of them to spend more time together. In coping with the pandemic, adult children provided instrumental support to their parents and parents reciprocated with emotional support. Participants also coped by making meaning of their situation during discussions. CONCLUSIONS: Findings characterize the resilience of persons with dementia and the mutuality of the relationship between both members of the care partner dyad, as both parents and adult children offered support to one another. Facilitating dyadic discussions may be a cost-effective way to sustain social connections and offer ongoing coping support through the pandemic or other challenging circumstances.

Step-by-step guide for electrochemical generation of highly oxidizing reactive species on BDD for beginners.

Selecting the ideal anodic potential conditions and corresponding limiting current density to generate reactive oxygen species, especially the hydroxyl radical (•OH), becomes a major challenge when venturing into advanced electrochemical oxidation processes. In this work, a step-by-step guide for the electrochemical generation of •OH on boron-doped diamond (BDD) for beginners is shown, in which the following steps are discussed: i) BDD activation (assuming it is new), ii) the electrochemical response of BDD (in electrolyte and ferri/ferro-cyanide), iii) Tafel plots using sampled current voltammetry to evaluate the overpotential region where •OH is mainly generated, iv) a study of radical entrapment in the overpotential region where •OH generation is predominant according to the Tafel plots, and v) finally, the previously found ideal conditions are applied in the electrochemical degradation of amoxicillin, and the instantaneous current efficiency and relative cost of the process are reported.

A review of cardiac troponin I detection by surface enhanced Raman spectroscopy: Under the spotlight of point-of-care testing.

Cardiac troponin I (cTnI) is a biomarker widely related to acute myocardial infarction (AMI), one of the leading causes of death around the world. Point-of-care testing (POCT) of cTnI not only demands a short turnaround time for its detection but the highest accuracy levels to set expeditious and adequate clinical decisions. The analytical technique Surface-enhanced Raman spectroscopy (SERS) possesses several properties that tailor to the POCT format, such as its flexibility to couple with rapid assay platforms like microfluidics and paper-based immunoassays. Here, we analyze the strategies used for the detection of cTnI by SERS considering POCT requirements. From the detection ranges reported in the reviewed literature, we suggest the diseases other than AMI that could be diagnosed with this technique. For this, a section with information about cardiac and non-cardiac diseases with cTnI release, including their release kinetics or cut-off values are presented. Likewise, POCT features, the use of SERS as a POCT technique, and the biochemistry of cTnI are discussed. The information provided in this review allowed the identification of strengths and lacks of the available SERS-based point-of-care tests for cTnI and the disclosing of requirements for future assays design.

Vigilancia de la resistencia a los antimicrobianos en cepas de Neisseria gonorrhoeae aisladas en Paraguay. Año 2021

Neisseria gonorrhoeae (N. gonorrhoeae) es el agente causal de la gonorrea, infección de transmisión sexual (ITS) que corresponde a la segunda causa más frecuente de ITS a nivel mundial, provocando una alta morbilidad y costo en atención de salud. En las últimas décadas han aumentado los reportes a nivel mundial de cepas resistentes a penicilina, sulfonamidas, tetraciclina, macrólidos y fluoroquinolonas, y más recientemente a azitromicina y cefalosporinas de espectro extendido como ceftriaxona y cefixima. El objetivo principal de este estudio fue determinar la sensibilidad a los antimicrobianos en cepas de N. gonorrhoeae que fueron enviadas al Laboratorio Central de Salud Pública (LCSP), por los centros colaboradores de la Red de Vigilancia Laboratorial de la Resistencia a los Antimicrobianos (RAM). Para ello, se realizó un estudio prospectivo de corte transversal de enero a diciembre de 2021. Se caracterizaron 128 cepas como N. gonorrhoeae a las cuales se le realizaron pruebas de susceptibilidad obteniéndose 48% de resistencia y 52% de sensibilidad intermedia a penicilina. El 70% presentó resistencia a ciprofloxacina y el 19% a tetraciclina. Se obtuvo 100% de sensibilidad a ceftriaxona y cefixima. El fenotipo de resistencia de mayor prevalencia fue QRNG, asociado con resistencia a ciprofloxacina, seguido del fenotipo PPNG-QRNG, asociado con resistencia a penicilina y ciprofloxacina. Ante estos hallazgos y frente a la emergencia mundial de la resistencia a los antimicrobianos, especialmente de cefalosporinas de espectro extendido, se recomienda que los laboratorios de bacteriología fortalezcan la vigilancia para apoyar la detección de casos y proporcionar el tratamiento adecuado.

Neisseria gonorrhoeae (N. gonorrhoeae) is the causal agent of gonorrhea, a sexually transmitted infection (STI) that is the second most common cause of STIs worldwide, causing high morbidity and cost in health care. In recent decades, reports of strains resistant to penicillin, fluoroquinolones, sulfonamides, tetracycline, macrolides, and more recently to azithromycin and extended-spectrum cephalosporins such as ceftriaxone and cefixime have increased worldwide. The main objective of this study was to determine the sensitivity to antimicrobials in N. gonorrhoeae strains that were sent to the Central Laboratory of Public Health (LCSP), by the collaborating centers of the Antimicrobial Resistance Laboratory Surveillance Network (RAM). For this, a prospective cross-sectional study was carried out from January to December, 2021. One hundred eighty strains were characterized as N. gonorrhoeae, which were subjected to sensitivity tests, obtaining 48% resistance and 52% intermediate sensitivity to penicillin while 70% presented resistance to ciprofloxacin and 19% to tetracycline. Also, 100% sensitivity to ceftriaxone and cefixime was obtained. The most prevalent resistance phenotype was QRNG, associated with resistance to ciprofloxacin, followed by the PPNG-QRNG phenotype, associated with resistance to penicillin and ciprofloxacin. Given these findings and the global emergence of antimicrobial resistance, especially extended-spectrum cephalosporins, it is recommended that bacteriology laboratories fortify surveillance to support case detection and provide appropriate treatment.

A Review on SERS-Based Detection of Human Virus Infections: Influenza and Coronavirus.

The diagnosis of respiratory viruses of zoonotic origin (RVsZO) such as influenza and coronaviruses in humans is crucial, because their spread and pandemic threat are the highest. Surface-enhanced Raman spectroscopy (SERS) is an analytical technique with promising impact for the point-of-care diagnosis of viruses. It has been applied to a variety of influenza A virus subtypes, such as the H1N1 and the novel coronavirus SARS-CoV-2. In this work, a review of the strategies used for the detection of RVsZO by SERS is presented. In addition, relevant information about the SERS technique, anthropozoonosis, and RVsZO is provided for a better understanding of the theme. The direct identification is based on trapping the viruses within the interstices of plasmonic nanoparticles and recording the SERS signal from gene fragments or membrane proteins. Quantitative mono- and multiplexed assays have been achieved following an indirect format through a SERS-based sandwich immunoassay. Based on this review, the development of multiplex assays that incorporate the detection of RVsZO together with their specific biomarkers and/or secondary disease biomarkers resulting from the infection progress would be desirable. These configurations could be used as a double confirmation or to evaluate the health condition of the patient.

Indirect Quantification of Glyphosate by SERS Using an Incubation Process With Hemin as the Reporter Molecule: A Contribution to Signal Amplification Mechanism.

The indirect determination of the most used herbicide worldwide, glyphosate, was achieved by the SERS technique using hemin chloride as the reporter molecule. An incubation process between hemin and glyphosate solutions was required to obtain a reproducible Raman signal on SERS substrates consisting of silicon decorated with Ag nanoparticles (Si-AgNPs). At 780 nm of excitation wavelength, SERS spectra from hemin solutions do not show extra bands in the presence of glyphosate. However, the hemin bands increase in intensity as a function of glyphosate concentration. This allows the quantification of the herbicide using as marker band the signal associated with the ring breathing mode of pyridine at 745 cm-1. The linear range was from 1 × 10-10 to 1 × 10-5 M and the limit of detection (LOD) was 9.59 × 10-12 M. This methodology was successfully applied to the quantification of the herbicide in honey. From Raman experiments with and without silver nanoparticles, it was possible to state that the hemin is the species responsible for the absorption in the absence or the presence of the herbicide via vinyl groups. Likewise, when the glyphosate concentration increases, a subtle increase occurs in the planar orientation of the vinyl group at position 2 in the porphyrin ring of hemin over the silver surface, favoring the reduction of the molecule. The total Raman signal of the hemin-glyphosate incubated solutions includes a maximized electromagnetic contribution by the use of the appropriate laser excitation, and chemical contributions related to charge transfer between silver and hemin, and from resonance properties of Raman scattering of hemin. Incubation of the reporter molecule with the analyte before the conjugation with the SERS substrate has not been explored before and could be extrapolated to other reporter-analyte systems that depend on a binding equilibrium process.

Hasta el momento, la enfermedad COVID-19 ha demostrado tener implicaciones funcionales a corto, y en ocasiones, a largo plazo. Ante la emergencia sanitaria desencadenada por esta enfermedad, el Colegio Colombiano de Terapia Ocupacional convocó a un grupo de profesionales expertas en el área para proveer lineamientos para terapeutas ocupacionales que se involucren en la rehabilitación intrahospitalaria y ambulatoria de usuarios con COVID-19 en Colombia. Se realizó una revisión de la literatura sobre el rol y la efectividad de la Terapia Ocupacional en la rehabilitación hospitalaria, las complicaciones reportadas en usuarios con COVID-19, y su manejo terapéutico en la rehabilitación intrahospitalaria y ambulatoria. Un consenso de expertas determinó la aplicabilidad de los lineamientos al contexto colombiano. La Terapia Ocupacional, como parte del equipo de rehabilitación, incide de manera directa en el nivel de independencia, la autonomía y la futura reincorporación a las actividades dentro de la sociedad; adicionalmente, facilitando y promoviendo actividades cognitivas, psicosociales y de ocio, aporta al mantenimiento del equilibrio ocupacional para prevenir la aparición de disfunciones de índole sensoriomotor, perceptivo y psicosocial a corto, mediano y largo plazo. Estos lineamientos constituyen un recurso técnico y educativo relevante para la Terapia Ocupacional hospitalaria.

Up to this date, COVID-19 disease has shown to have short-term, and sometimes long-term, functional implications. Faced with the health emergency triggered by this disease, the Colombian College of Occupational Therapy convened a group of professional experts in the area to provide guidelines for occupational therapists involved in inpatient and outpatient rehabilitation of users with COVID-19 in Colombia. A literature review was conducted on the role and effectiveness of Occupational Therapy in subacute rehabilitation, the complications reported in users with COVID-19, and its therapeutic management in inpatient and outpatient rehabilitation. A consensus of experts determined the applicability of the guidelines to the Colombian context. Occupational Therapy, as part of the rehabilitation team, directly affects the level of independence, autonomy and future reincorporation to the activities within society. It also contributes to maintaining occupational balance to prevent short, medium, and long term sensorimotor, perceptual, and psychosocial dysfunctions, by facilitating and promoting cognitive, psychosocial, and leisure activities. These guidelines constitute a relevant technical and educational resource for subacute care in Occupational Therapy.

Até agora, foi demonstrado que a doença COVID-19 tem implicações funcionais de curto e, às vezes, de longo prazo. Diante da emergência sanitária desencadeada por esta doença, o Colégio Colombiano de Terapia Ocupacional reuniu um grupo de profissionais, especializados na área, para fornecer orientações aos terapeutas ocupacionais, envolvidos na reabilitação hospitalar e ambulatorial de usuários com COVID-19, na Colômbia. Foi realizada uma revisão da literatura sobre o papel e a eficácia da Terapia Ocupacional na reabilitação hospitalar, as complicações relatadas em usuários com COVID-19 e seu manejo terapêutico na reabilitação hospitalar e ambulatorial. Um consenso de especialistas determinou a aplicabilidade das diretrizes ao contexto colombiano. A Terapia Ocupacional, como parte da equipe de reabilitação, afeta diretamente o nível de independência, autonomia e futura reincorporação às atividades na sociedade; além disso, facilitando e promovendo atividades cognitivas, psicossociais e de lazer, contribui para a manutenção do equilíbrio ocupacional, para prevenir o aparecimento de disfunções sensório-motoras, perceptivas e psicossociais em curto, médio e longo prazo. Tais orientações constituem um recurso técnico e educacional importante para a Terapia Ocupacional hospitalar.

Emerging pollutant treatments in wastewater: Cases of antibiotics and hormones.

Because of the intensive use of pharmaceutical substances in human life, studies on the detection of these chemical compounds and their metabolites as pollutants in water bodies are continuously reported. Some pharmaceutical agents are associated with adverse effects to aquatic life, even at very low concentrations (ng L-1 to µg L-1). For instance, the presence of antibiotics and hormones has been associated with increasing proliferation of antibiotic resistant pathogens and feminization and masculinization of some aquatic organisms. Currently, new attempts are being made to minimize or fully remove these types of pollutants from aquatic systems to protect the environment and human health. In this regard, physicochemical and biological treatments are among the most promising technologies for the treatment of wastewater containing pharmaceutical pollutants. These treatments are green alternatives for the degradation of hazardous organic compounds into nontoxic by-products. Here, we review some of the physicochemical and biological treatment methods used for the removal of the most extensively used antibiotics and hormones. Enzymatic oxidation, photocatalysis and electrochemical oxidation are described in terms of the aforementioned pharmaceutically active compounds (PhACs). The use of membrane technologies to separate different groups of antibiotics and hormones prior to biologic or physicochemical treatment methods is also addressed.

Neumonitis por citomegalovirus durante el tratamiento crónico con metotrexato / Pneumonitis due to cytomegalovirus during chronic methotrexate treatment

Si bien la neumonitis por hipersensibilidad es la complicación pulmonar más frecuentemente descrita durante el tratamiento con metotrexato, existen otras complicaciones de tipo linfoproliferativo e infeccioso que hay que tener en cuenta dentro del diagnóstico diferencial ante una neumopatía en el contexto de dicho tratamiento. La existencia de un riesgo incrementado de desarrollar procesos infecciosos o reactivaciones de microorganismos latentes puede ser similar al observado a lo largo del tratamiento con antagonistas del factor de necrosis tumoral y corticoides. Dentro de ellas, la neumonía por citomegalovirus es una complicación muy severa a tener en cuenta, ya que el diagnóstico acertado y el tratamiento oportuno evitarán un desenlace potencialmente mortal (AU)

Although hypersensitivity pneumonitis is the most common pulmonary complication described during treatment with methotrexate, other complications like lymphoproliferative and infectious disease may be considered in the study of respiratory disease associated to methotrexate. The existence of an increased risk to developing infectious diseases may be similar to that observed during treatment with antagonists of tumor necrosis factor and corticosteroids, where Cytomegalovirus pneumonia is a serious complication; early diagnosis and treatment will prevent a potentially fatal outcome (AU)
