Bioremoval of copper by filamentous fungi isolated from contaminated soils of Puchuncaví-Ventanas Central Chile.

Pollution represents a high risk to plants, animals, and human beings, causing an imbalance and affecting the environment. Soil is considered a universal sink, containing the highest load of environmental pollution. Puchuncaví-Ventanas sector, decreed as a saturated contamination zone in 1993, is considered one of the most affected areas by industrial pollution and belongs to one of the 5 sacrifice zones of Chile. The localities of Puchuncaví and Ventanas have heavy metal pollution levels that exceed up to 99% of the limits allowed by Canadian standards. The objective of this study was to characterize heavy metal tolerance and removal potential of filamentous fungi isolated from polluted soils for their use in decontamination systems and in situ soil improvement. Six fungal strains were selected based on their tolerance and a high capability to accumulate heavy metals, achieving copper bioaccumulation of 84% (Mortierella sp. strain LG01), 49% (Clonostachys sp. strain CQ23) and 48-77.5% (Trichoderma sp. strain LM01A). Trichoderma sp. strain LM01A was able to remove 41% of copper from contaminated soil under ex situ conditions. Some fungal strains belong to beneficial fungal genera, which are used as bioproducts in agriculture. The results of this study highlighted the use of Trichoderma sp. in soils contaminated, which may be of special interest in agriculture due to the large amounts of copper sulfate still applied as a pesticide in Chile and the world.

A comparative study between real-time PCR and loop-mediated isothermal amplification to detect carbapenemase and/or ESBL genes in Enterobacteriaceae directly from bronchoalveolar lavage fluid samples.

OBJECTIVES: To evaluate and compare the efficacy of real-time PCR (Xpert Carba-R) and loop-mediated isothermal amplification (Eazyplex® SuperBug CRE) for detecting carbapenemase carriage in Enterobacteriaceae directly from bronchoalveolar lavage (BAL). METHODS: Negative BAL samples were spiked with 21 well-characterized carbapenemase-producing Enterobacteriaceae strains to a final concentration of 102-104 cfu/mL. Xpert Carba-R (Cepheid, Sunnyvale, CA, USA), which detects five targets (blaKPC, blaNDM, blaVIM, blaOXA-48 and blaIMP-1), and the Eazyplex® SuperBug CRE system (Amplex-Diagnostics GmbH, Germany), which detects seven genes (blaKPC, blaNDM, blaVIM, blaOXA-48, blaOXA-181, blaCTXM-1 and blaCTXM-9), were evaluated for the detection of these genes directly from BAL samples. RESULTS: Xpert Carba-R showed 100% agreement with carbapenemase characterization by PCR and sequencing for all final bacteria concentrations. Eazyplex® SuperBug CRE showed 100%, 80% and 27% agreement with PCR and sequencing when testing 104, 103 and 102 cfu/mL, respectively. False negative results for Eazyplex® SuperBug CRE matched the highest cycle threshold values for Xpert Carba-R. Hands-on time for both assays was about 15 min, but Eazyplex® SuperBug CRE results were available within 30 min, whereas Xpert Carba-R took around 50 min. CONCLUSIONS: We here describe the successful use of two commercial diagnostic tests, Xpert Carba-R and Eazyplex® SuperBug CRE, to detect bacterial carbapenem resistance genes directly in lower respiratory tract samples. Our results could be used as proof-of-concept data for validation of these tests for this indication.

Cytomegalovirus infection in HIV-infected patients in the era of combination antiretroviral therapy.

BACKGROUND: Cytomegalovirus infection dramatically decreased with the introduction of antiretroviral therapy. Whether incidence, clinical characteristics and prognosis of cytomegalovirus in HIV infected patients, has changed over time is. scarcely known. METHODS: Retrospective single-center study. Patients included in this study were all HIV infected patients that went to our center for any disease, and were diagnosed with cytomegalovirus, during the period 2004-2015. epidemiological, clinical and laboratory patients variables were collected in a clinical database. Clinical characteristics, incidence of cytomegalovirus and predictors of mortality during the study were assessed. Results were considered statistically significant when p < 0.05. All statistical analyses were calculated by SPSS version 20.0 (Chicago, IL,USA). RESULTS: Fifty-six cases of cytomegalovirus infection, in HIV infected patients were identified during the study period (incidence rate-1.7 cases per 1000 persons/year). The most frequent presentation was systemic illness in 43% of cases. Of note,no patients presented with ophthalmic manifestations. The 30-days mortality was 18%. Predictors of mortality were, in the univariate analysis, admission to the intensive care unit OR 32.4 (3.65-287.06) p = 0.0001, and mechanic ventilation 84 OR (8.27-853.12) p = 0.0001, and ART OR 4.1 (0.97-17.31) p = 0.044. These variables were assessed by multivariate analysis, and only mechanical ventilation was statistically significant (p < 0.05) CONCLUSION: Incidence of cytomegalovirus infection was higher than described in the antiretroviral therapy era. Clinical presentation has changed. Mechanic ventilation predicted mortality.

Implementation of MALDI-TOF MS technology for the identification of clinical isolates of Mycobacterium spp. in mycobacterial diagnosis.

A total of 243 clinical isolates of the Mycobacterium genus were studied, 143 and 100 using two protocols (Protocol v2 and Protocol v3, respectively) provided by the manufacturer. The overall correlation of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) with the standard identification methods was 63.8 %. The rate of misidentification was 3.2 %, mainly affecting very close species. In Protocol v2, the correlation was 57.3 %, being greater in solid than in liquid media (71.7 % vs. 44.7 %, p < 0.05). Albeit not significant, a trend to a greater correlation for M. tuberculosis complex compared to non-tuberculous mycobacteria (NTM) (63.6 % vs. 55.5 %) was observed. In Protocol v3, the correlation was 73 %, with no significant differences between solid and liquid media (70.8 % vs. 75 %). In conclusion, MALDI-TOF MS may play a role in identifying mycobacterial species isolated from clinical samples, being faster than sequencing and hybridization-based techniques.

Translation, adaptation, and cross-cultural validation of the CDQ-24 scale in patients with primary blepharospasm under botulinum toxin treatment, pilot test.

BACKGROUND: Benign essential blepharospasm (BEB) is the most common adult-onset focal facial dystonia and its treatment of choice is periodic application of botulinum toxin (BtA). It has a higher incidence in middle and late adulthood, especially in women between 40 and 60 years of age. OBJECTIVE: To carry out the translation and cross-cultural adaptation of the CDQ24 questionnaire in its Spanish version in patients diagnosed with BEB who have been treated with BtA in an ophthalmologic center in Bogotá - Colombia. MATERIALS AND METHODS: Pilot test of validation study and adaptation of a scale assembled in a prospective cohort of the CDQ24 instrument to Spanish in adult patients with primary blepharospasm treated with botulinum toxin in Bogota, Colombia. RESULTS: We obtained a sample of 26 patients to whom the instrument was applied after translation and retranslation of the original document, composed of 19 (73%) women with a median age of 64.5 years; the average time to answer the survey was 4.93 min. The internal consistency of the scale evaluated by Cronbach's Alpha had a total score of 0.78. Criterion validity between the CDQ24 scale and the WHOQOL-BREF quality of life scale was determined by determining correlation between the Emotional Well-Being and Phsychological domains of both scales. CONCLUSIONS: The translation and cross-cultural adaptation of the CDQ-24 scale into Spanish allowed the applicability of the instrument to the Spanish-speaking population during the pilot test, which allows us to continue the relevant studies in the study population.

[National competitive bidding analysis of osteosynthesis materials in pediatric patients with femur fractures]. / Análisis de licitación pública nacional de materiales de osteosíntesis en los pacientes pediátricos con fracturas de fémur.

INTRODUCTION: health promotion policy requires the identification of barriers to the adoption of public policies. Paraguay's national healthcare system is inequitable, expensive, and inefficient. The Ministry of Public Health and Social Welfare (MSPyBS) is the entity responsible for covering the needs of a significant portion of the population. In January 2022, the MSPyBS financed the purchase of titanium elastic nails through a National Public Tender for Osteosynthesis Materials (LPN 02/22) to provide them for free in the pediatric service. Using research as a tool, we seek to analyze the impact of the implementation of LPN 02/22 at the Trauma Hospital, believing that this action would help streamline administrative and bureaucratic processes, making them more efficient with the assistance of the hospital's human resources. MATERIAL AND METHODS: a retrospective, analytical, and comparative study conducted at a high-complexity trauma center in Asunción, Paraguay. Patients aged 4 to 14 years with an indication for stabilization with elastic nails were included. Demographic data, the mechanism of injury, time elapsed from hospital arrival to surgical treatment, length of hospital stay, and the average hospital cost were analyzed based on the daily expense of pediatric patient hospitalization. RESULTS: 52 patients, divided into 25 cases in 2021 before implementation and 27 cases after implementation. The time elapsed from hospital arrival to definitive treatment was six days in the pre-implementation period, with an average stay from admission to discharge of 7.4 days. After implementation, the time from hospital arrival to definitive treatment was 4.3 days, and the average discharge time for the Post group was six days. The potential savings per patient amount to 332 dollars, offset by the institution's implant supply cost of 197 dollars, resulting in an approximate savings of 135 dollars per patient for the ministry. CONCLUSIONS: we view the implementation of free titanium elastic nails for pediatric femur fracture patients positively. We encourage the institution to continue with similar policies and strive to achieve even greater benefits for users.

INTRODUCCIÓN: la política de promoción de la salud requiere la identificación de los obstáculos para la adopción de políticas públicas. El sistema nacional de salud de Paraguay es inequitativo, caro e ineficiente. El Ministerio de Salud Pública y Bienestar Social (MSPyBS) es el ente que cubre las necesidades de gran parte de la población. El MSPyBS en Enero del 2022 financió, mediante la Licitación Pública Nacional de Materiales de Osteosíntesis (LPN 02/22), la compra de clavos elásticos de titanio para disponer de su uso gratuito en el Servicio de Pediatría; usando a la investigación como herramienta, buscamos analizar el impacto de la implementación de la LPN 02/22 en el Hospital de Trauma, creyendo que esta acción ayudaría a dinamizar los procesos administrativos y burocráticos, haciéndolos más eficientes con la ayuda de los recursos humanos del hospital. MATERIAL Y MÉTODOS: estudio retrospectivo, analítico y comparativo, realizado en un centro de trauma de alta complejidad de Asunción, Paraguay. Fueron incluidos los pacientes con edad comprendidas entre cuatro y 14 años, con indicación de estabilización con clavos elásticos. Se analizaron los datos demográficos, el mecanismo de trauma, el tiempo transcurrido desde la llegada al hospital hasta el tratamiento quirúrgico, así como el tiempo de estadía hospitalaria. Se evaluó el costo hospitalario promedio, basados en el gasto diario de la internación de un paciente pediátrico. RESULTADOS: cincuenta y dos pacientes, separados en 25 casos en el 2021 previo a la implementación y 27 casos posterior a la implementación. El tiempo transcurrido desde la llegada al hospital hasta el tratamiento definitivo fue de seis días para la etapa previa a la implementación; el promedio desde el ingreso hasta el alta fue de 7.4 días. Desde la implementación se tuvo un transcurso de 4.3 días desde la llegada al hospital hasta el tratamiento definitivo. El egreso del grupo Post tuvo un promedio de seis días. El ahorro probable en relación con cada paciente es de 332 dólares; a esto debemos contrarrestar el monto que paga la institución para la provisión del implante (197 dólares), por lo que el ahorro del ministerio sería de aproximadamente 135 dólares por cada paciente. CONCLUSIONES: vemos como positiva la implementación de la gratuidad de los clavos elásticos de titanio en los pacientes en edad pediátrica con fractura de fémur. Alentamos a la institución a seguir con políticas similares y tratar de lograr mayores beneficios para los usuarios.

Comparative morphology of pre-extrusion larvae, Sebastes mentella and Sebastes norvegicus (Pisces: Sebastidae) in Icelandic waters.

This study evaluated potential differences in morphology of unextruded larvae from Sebastes mentella and Sebastes norvegicus in Icelandic waters. Fifty-four larvae of each species were measured, and 18 measurements were recorded for each specimen (morphometric, meristic and pigmentation patterns). Pre-extrusion larvae of S. norvegicus were longer than those of S. mentella. Additionally, there were significant differences in morphometric, meristic and pigmentation characters between pre-extrusion larvae of these species. Pigmentation of S. mentella differed from that of S. norvegicus in several aspects. Dorsal and ventral body pigmentation tended to begin more posteriorly in S. mentella, therefore, the overall length of these pigmented areas tended to be longer in S. norvegicus.

Translation and transcultural adaptation of the AS-20 scale to measure quality of life in adults with strabismus in Colombia, a pilot study.

BACKGROUND: Strabismus generates a negative psychosocial impact on adult patients, affecting aspects such as self-perception and quality of life. There is no scale in Colombian Spanish that measures these impacts. OBJECTIVE: To carry out the translation and cross-cultural adaptation of the AS-20 instrument into Colombian Spanish. MATERIALS AND METHODS: Pilot test of a cross-sectional Study for the translation, reverse translation, and cross-cultural the AS-20 instrument from its original language, English, to Colombian Spanish, in adult patients with strabismus in Bogotá, Colombia. RESULTS: 16 patients were assessed. The age range was between 18 and 68 years with a mean age of 41 years. The scale was answered in an average time of 10.62min. Difficulty was reported in three individuals for understanding two items (questions 8 and 14), which were resolved. CONCLUSION: The translation and pilot test of AS-20 scale into Colombian Spanish was carried out, identifying and solving translational difficulties. Is the first step in the cross-cultural adaptation process. Based on the results, the validation and cross-cultural adaptation can be completed in a future study.

Antimicrobial resistance pattern of methicillin-resistant Staphylococcus aureus in the food industry.

There is increasing concern about the impact on public health of methicillin-resistant Staphylococcus aureus (MRSA) associated with animal food products. MRSA remains a serious problem because of the high incidence and multidrug resistance of the strains, even for strains isolated from foods, food environments and food handlers. The objectives of this study are: (i) to evaluate the susceptibility of S. aureus strains isolated from food, food handlers and food-processing environments to 14 antibiotics currently used in veterinary and human therapy; (ii) to assess the presence of the mecA gene. A total of 1007 samples were collected from food, food handlers, and environments and were analyzed for the presence of S. aureus. S. aureus was present in 165 of the 1007 samples. A total of 157 isolates were methicillin-susceptible S. aureus (MSSA) and 8 isolates were MRSA. In particular, out of 8 MRSA strains detected, 4 strains harboured the mecA gene. All MRSA strains were resistant to at least one of the tested antibiotics and 6 strains demonstrated multi-resistance. Considering the high level of resistances in S. aureus and the isolation of MRSA strains, the surveillance of antimicrobial resistance and the spreading of this pathogen is of crucial importance in the food production chain. These data are useful in improving background data on antimicrobial resistance of S. aureus isolated from food, processing environments and food handlers, supporting the prudent use of antibiotics and the development of international control programs.

[Pregnancy and inflammatory bowel disease: experience in 17 patients]. / Enfermedad inflamatoria intestinal y embarazo: experiencia de 16 años.

BACKGROUND: Inflammatory bowel disease (IBD) has a peak incidence between 15 and 25 years of age, thereby affecting women of reproductive age. Fertility rates with inactive IBD are similar to the general population, and drugs currently used, with the exception of methotrexate and thalidomide, have a good safety and efficacy profile during pregnancy. Starting a pregnancy with inactive IBD significantly reduces the potential maternal and fetal complications. AIM: To assess the evolution of pregnancy and the underlying disease in women with IBD. PATIENTS AND METHODS: Retrospective and prospective study of female patients with IBD controlled in our hospital who became pregnant from January 1994 to February, 2011. RESULTS: We followed 17 patients with a total of 19 pregnancies. In two patients the onset of IBD occurred during pregnancy and from the remaining, 11 patients became pregnant during remission of IBD. Most of the patients continued the same treatment during pregnancy and the few flares that occurred were treated satisfactorily. Major complications occurred in three patients, all associated with IBD activity. Fifteen patients had full-term deliveries and the majority of the newborns had normal weight and Apgar score. None had malformations. CONCLUSIONS: Pregnancies among patients with an inactive IBD, have a good evolution. A multidisciplinary approach and patient education are invaluable to achieve these good results.

[Comparison of real-time polymerase chain reaction and antigenemia assay to detect cytomegalovirus in pediatric transplants]. / Comparación de las técnicas de reacción de polimerasa en cadena en tiempo real y antigenemia para la detección de citomegalovirus en sangre de niños sometidos a trasplantes.

BACKGROUND: Cytomegalovirus (CMV) infections are an important cause of morbidity and mortality in transplant recipient. To date, the antigenemia assay is the most used technique for diagnostic and management of CM V infections. However, quantification of CMV viral load by real time polymerase chain reaction (RT-PCR) has becoming the method of choice to detect CMV in a rapid, sensitive and specific manner. OBJECTIVE: To compare antigenemia and RT-PCR assays in the detection of CMV in blood sample from solid organ and bone marrow transplant (BMT) in children attended at the Dr. Luis Calvo Mackenna Hospital. METHODS: In a prospective study, we detect the presence of CMV in blood sample by RT-PCR and antigenemia assays. RESULTS: We analyzed 219 blood samples from 68 children subjected to kidney, liver and BMT. Out of 219 samples analyzed, 147 were negative and 33 were positive for CMV by both techniques. Thirty-seven samples were positive only by RT-PCR and 2 by antigenemia. Considering the antigenemia as a reference, RT-PCR shows 94%, 80%, 34% and 99% sensitivity, specificity, positive and negative predictive values, respectively. The kappa coefficient between both techniques was 0.528. CONCLUSION: Quantitative determination of CMV viral load by RT-PCR is a sensitive technique with excellent negative predictive valué compared to antigenemia. Our results support the use of RT-PCR as a technique that might facilítate the diagnostic and treatment of active CMV infection in pediatric transplants.

[Paramedian forehead flap for the reconstruction of extensive nasal defects]. / Colgajo fronto-nasal paramedial en la reconstrucción de defectos nasales extensos.

BACKGROUND: The Department of Dermatology at Hospital Universitario de Guadalajara in Spain is a referral center for Mohs micrographic surgery. Consequently, we are regularly faced with the problem of repairing large surgical defects on the nose. The paramedian forehead flap is currently one of the techniques of choice for the repair of such defects. MATERIALS AND METHODS: We review our experience in the repair of nasal defects using the paramedian forehead flap over the period from 2004 to 2008. We describe the surgical technique, complications, and final results. RESULTS: Ten patients (mean age, 75.1 years) were treated using this flap. Two patients also required cartilage grafts and reconstruction of the internal nasal lining. The most common complications were bleeding (60%) and partial necrosis (10%). The final cosmetic and functional results were considered good or excellent in 90% of cases. CONCLUSIONS: The forehead flap continues to be one of the best options for the closure of surgical defects of the nasal pyramid larger than 2 cm. Adequate knowledge and careful application of the technique allows excellent results to be obtained with few complications.

[The renin-angiotensin system and the brain]. / El rol del sistema renina angiotensina a nivel cerebral.

The renin-angiotensin-aldosterone (RAAS) system and its effects on blood pressure and the regulation of water and electrolyte balance have been studied focusing on the cardiovascular and renal system. The activation of RAAS in other organs has local and systemic repercussions by modeling the macro- and microvasculture of peripheral organs. The brain RAAS influence on systemic blood pressure through the sympathetic nervous system. The angiotensin converting enzyme/angiotensin II/angiotensin 1 receptor axis (ACE/AngII/AT1), classical pathway, and angiotensin converting enzyme type 2/angiotensin (1-7)/Mas receptor (ACE2/Ang (1-7)/MasR), non-classical pathway, are involved in the modulation of the sympathetic response. The imbalance of these two axes with subsequently Ang II accumulation promote neurogenic hypertension and other vascular pathologies. The aminopeptidase/angiotensin IV/angiotensin 4 receptor (AMN/Ang IV/AT4) axis, which is exclusive of the brain, acts on cerebral microvasculature and participates in cognition, memory, and learning. The aim of this review is to decipher the major central RAAS mechanisms involved in blood pressure regulation. In addition, paracrine functions of brain RAAS and its role in neuroprotection and cognition are also described in this review.

[Malignant hypertension and pheochromocytoma: a case report]. / Hipertensión maligna y feocromocitoma: reporte de un caso.

Malignant arterial hypertension is defined by extremely high levels of pressure associated with organ damage. It is a cause of hypertensive emergency and is defined by the coexistence of high blood pressure and bilateral retinal haemorrhage or exudates (grade III hypertensive retinopathy), with or without papilloedema (grade IV hypertensive retinopathy) currently associated with organ damage such as renal or cardiac failure. Around 1% of malignant arterial hypertension is secondary to endocrinological causes, including the most common: pheochromocytoma, which is classically characterized by the triad: headache, sweating and palpitations. However, there is no single clinical finding that is of significant value in its diagnosis. We now present the case of a 23-year-old patient with a hypertensive emergency, an adrenal mass associated with grade IV hypertensive retinopathy.

Effectiveness of omega-3 fatty acid supplementation in patients with Alzheimer disease: A systematic review and meta-analysis. / Efectividad de la suplementación de ácidos grasos omega-3 en pacientes con enfermedad de Alzheimer: revisión sistemática con metaanálisis.

INTRODUCTION: Alzheimer disease (AD) is a neurodegenerative disease characterised by progressive dementia associated with global cognitive dysfunction. METHODS: We conducted a systematic review and meta-analysis of clinical trials evaluating omega-3 supplementation in patients with AD. OBJECTIVE: To determine if there is scientific evidence of the effectiveness of omega-3 supplementation in improving cognitive function in patients with AD. SEARCH STRATEGY: We included only randomised controlled trials (RCTs) from the following databases: Medline, Cochrane Central, Cinahl, and LILACS. An electronic search was also conducted using Google Scholar. STUDY SELECTION: Six articles met the eligibility criteria. The risk of bias was assessed following the Cochrane method. CONCLUSION: There is no consistent evidence to support the effectiveness of omega-3 supplementation in improving cognitive function in AD patients in the short and medium term.

The relationship between antiretroviral prescription patterns and treatment guidelines in treatment-naïve HIV-1-infected patients.

BACKGROUND: Reports have shown that the publication of practice guidelines does not guarantee their use in clinical practice. The objective of this study was to evaluate the agreement between antiretroviral treatments (ARTs) prescribed in clinical practice and the recommendations in published guidelines. METHODS: A retrospective cohort study was carried out in ART-naïve adults of the Spanish Asociacion Medica Vach de Estudios Multicentricos (VACH) Cohort for the period from 2003 to 2006. RESULTS: A total of 945 patients initiated ART. Of these patients, 12.3% had a CD4 cell count above 350 cells/microL. A 'nonrecommended' antiretroviral regimen was prescribed to 5.3, 5.1 and 7.8% of patients with CD4 counts <200, 200-350 and >350 cells/microL, respectively. Multivariate analyses demonstrated that only a higher viral load was associated with the selection of a combination treatment that was recommended by the guidelines. CONCLUSIONS: Most patients were prescribed initial treatments in agreement with the recommendations. Appropriate routine data collection in databases can be used to evaluate the level of antiretroviral guideline compliance. We propose that routine evaluations of the guidelines must be part of quality assessment to improve medical care.

Influence of temperature on biofilm formation by Listeria monocytogenes on various food-contact surfaces: relationship with motility and cell surface hydrophobicity.

AIMS: To assess the ability of Listeria monocytogenes to form biofilm on different food-contact surfaces with regard to different temperatures, cellular hydrophobicity and motility. METHODS AND RESULTS: Forty-four L. monocytogenes strains from food and food environment were tested for biofilm formation by crystal violet staining. Biofilm levels were significantly higher on glass at 4, 12 and 22 degrees C, as compared with polystyrene and stainless steel. At 37 degrees C, L. monocytogenes produced biofilm at significantly higher levels on glass and stainless steel, as compared with polystyrene. Hydrophobicity was significantly (P < 0.05) higher at 37 degrees C than at 4, 12 and 22 degrees C. Thirty (68.2%) of 44 strains tested showed swimming at 22 degrees C and 4 (9.1%) of those were also motile at 12 degrees C. No correlation was observed between swimming and biofilm production. CONCLUSIONS: L. monocytogenes can adhere to and form biofilms on food-processing surfaces. Biofilm formation is significantly influenced by temperature, probably modifying cell surface hydrophobicity. SIGNIFICANCE AND IMPACTS OF THE STUDY: Biofilm formation creates major problems in the food industry because it may represent an important source of food contamination. Our results are therefore important in finding ways to prevent contamination because they contribute to a better understanding on how L. monocytogenes can establish biofilms in food industry and therefore survive in the processing environment.

Efectos de un programa de rehabilitación remota en atención primaria en salud, posterior al alta hospitalaria por COVID-19: estudio observacional / Effects of a remote rehabilitation program in primary health care, after hospital discharge due to COVID-19: observational study

Se ha reportado un importante daño sistémico de los pacientes afectados por COVID-19, y aún existen interrogantes sobre las secuelas a largo plazo. Surge ante esto la necesidad de plantear programas de rehabilitación de los sistemas primarios de atención, que respondan a estas necesidades. Se realizó un programa de 6 semanas de rehabilitación remota, con seguimiento y progreso semanal, posterior al alta hospitalaria por COVID-19 a 114 usuarios de 4 centros de atención primaria de la comuna de El Bosque, Santiago, R. Metropolitana. Se incluyó a pacientes de edades entre 21 y 93 años, combinando los principios del ejercicio terapéutico individualizado, una evaluación presencial previo y posterior a las 6 semanas de trabajo. Los indicadores evaluados fueron: Minimental Abreviado, 1 Minute Sit to Stand Test (1min STST), Timed Up and Go (TUG), índice de Barthel y FRAIL. Se hicieron análisis inferenciales y descriptivos y se encontraron mejoras favorables en los indicadores de condición física (TUG y 1'STST), Índice de Barthel y el Simple "FRAIL" Questionnaire Screening Tool (FRAIL). En conclusión, si bien la mayoría de los indicadores tuvieron resultados favorables, es necesario seguir estudiando herramientas de evaluación más sensibles e intervenciones específicas que se adapten a las necesidades de las personas.

Significant systemic damage has been reported in patients affected by COVID-19, and questions remain about long-term sequelae. Therefore, the need arises to propose rehabilitation programs for primary care systems that respond to these needs. A 6-week program of remote rehabilitation, with weekly follow-up and progress, after hospital discharge for COVID-19 was carried out on 114 users from 4 primary care centers in the commune of El Bosque, Santiago, Chile. The program included patients from 21 to 93 years-old, combining the principles of individualized therapeutic exercise, a face-to-face evaluation before and after 6 weeks of work. The indicators evaluated were: Abbreviated Minimental, 1 minute Sit to Stand Test (1 min STST), Timed Up and Go (TUG), Barthel index and the Simple "FRAIL" Questionnaire Screening Tool (FRAIL). Inferential and descriptive analyses were carried out and favorable improvements were found in the indicators of physical condition (TUG and 1min STST), Barthel Index and FRAIL. In conclusion, while most of the indicators had favorable results, it is required to further explore more sensitive assessment tools and targeted interventions that are tailored to people's needs.

Efectos de un programa de tele-rehabilitación en la capacidad física y disnea en atención primaria en salud, posterior al alta hospitalaria por COVID-19: estudio observacional / Effects of a tele-rehabilitation program on physical capacity and dyspnea in primary health care, after hospital discharge for covid-19: observational study

Resumen En marzo del año 2020, se declaró una pandemia de características mundiales, por un virus, que genera deterioro importante a nivel sistémico, SARS -CoV-2, con la enfermedad COVID-19. El deterioro funcional de quienes sufren secuelas post COVID-19 ha llevado a los profesionales de la rehabilitación a buscar formas eficientes de intervenir. Este estudio, descriptivo y retrospectivo, evaluó los efectos de un programa de rehabilitación remoto de 6 semanas, en 39 pacientes dados de alta de COVID-19, de un Centro de Salud Familiar (CESFAM) de la Comuna de El Bosque, Santiago, Chile, entre julio y diciembre del año 2020, analizando la capacidad física con el test 1 minuto sentado-de pie y disnea con escala de Borg modificada. Los resultados mostraron cambios estadísticamente significativos en la capacidad física y disnea de los pacientes intervenidos. Es necesario estudiar los beneficios de intervenciones específicas para esta población, y su impacto a largo plazo, entendiendo que convivimos con una nueva enfermedad, un COVID-19 prolongado, que incluso en cuadros leves está dejando secuelas funcionales importantes.

In March 2020, a pandemic of global characteristics was declared, due to a virus, which generates significant deterioration at the systemic level, SARS -CoV-2, with the COVID-19 disease. The functional deterioration of those suffering from post-COVID-19 sequelae has led rehabilitation professionals to look for efficient ways to intervene. This study, descriptive and retrospective, evaluated the effects of a 6-week remote rehabilitation program, in 39 patients discharged from COVID-19, from a Family Health Center in the Commune of El Bosque, Santiago, Chile, between July and December 2020, analyzing physical capacity with the 1 minute sitting-standing test and dyspnea with modified Borg's scale. The results showed statistically significant changes in the physical capacity and dyspnea of the operated patients. It is necessary to study the benefits of specific interventions for this population, and their long-term impact, understanding that we live with a new disease, a prolonged COVID, which even in mild cases is leaving important functional sequelae.
