RESUMO

BACKGROUND: Central nervous system opportunistic infections can be the first presentation of an HIV infection. Our aim is to describe clinical and laboratory characteristics of HIV-associated Cryptococcal Meningitis (CM), in-hospital outcomes and analyze associations of these parameters with adverse outcomes. METHODS: Observational study of local cohort of HIV-associated cryptococcal meningitis in a high complexity tertiary urban hospital in Santiago, Chile. Descriptive analysis through chart review of all episodes of HIV-associated CM in adults, from 1995 to 2019. Inclusion criteria were confirmed CM with cerebrospinal fluid culture or India ink in the appropriate clinical context and HIV diagnosis. We selected relevant variables that have been described as predictors of adverse outcomes in the literature and explore associations in our cohort. RESULTS: There were 37 HIV associated CM cases, occurring from 2000 to 2019. Majority were men (86 %) with a median age of 35 years. CM was the first HIV manifestation in 32 %. Opening pressure was measured in 10 % of patients at admission. Most CSF parameters were mildly altered, and two patients presented with completely normal CSF findings. Most patients -94,4 %- suffered adverse events secondary to antifungal therapy. Despite of recommendations against their use, steroids were frequently prescribed. Mortality was 18,9 %, and was associated with older age, and more days of headache prior to admission. CONCLUSIONS: CM clinical presentation and CSF characteristics are variable at presentation, which can lead to delayed diagnosis. Inappropriate use of corticosteroids, antifungal toxicity and suboptimal management of elevated intracranial pressure are key aspects to improve.

RESUMO

RESUMEN Introducción : La pandemia por COVID-19 ha conmocionado a la humanidad. Durante la misma, la necesidad de aislamiento social ha fomentado la baja adherencia a un estilo de vida saludable en muchos individuos. Sin embargo, existe poca evidencia del impacto metabólico que ha tenido la pandemia por COVID-19 en nuestro medio. Objetivos : Evaluar el impacto del aislamiento social producido por la pandemia COVID-19 sobre el peso corporal y los pará metros cardiometabólicos de una población de adultos en la Ciudad Autónoma de Buenos Aires. Materiales y métodos : En un diseño observacional, se analizaron los datos de pacientes (pac.) que asistieron a un programa de prevención y promoción de salud en la Ciudad de Buenos Aires. Se individualizaron datos de participantes que concurrieron a realizarse estudios en el año 2019 y repitieron los mismos en el año 2021. Los registros médicos se utilizaron como fuente para la recopilación de datos generales, medidas antropométricas y valores de laboratorios. Se utilizaron los criterios NCEP para definir la presencia de Síndrome Metabólico (SM). Resultados : Se identificaron un total de 558 pac. con evaluaciones disponibles en 2019 y 2021. La edad promedio de la población fue 52,2 ± 12,8 años, con 41% de mujeres. Se observó un incremento en el peso corporal (82,1 ± 17,7 kg vs. 83,1 ± 18,5kg; p <0,0001) y del índice de masa corporal (29,4 ± 5,4 vs. 29,8 ± 5,7, p <0,0001). También se observaron incrementos en la presión arterial sistólica (123,1 ± 15,1 mmHg vs. 126,6 ± 16,3 mmHg; p <0,0001) y diastólica (77,7 ± 9,3 mmHg vs. 79,6 ± 9,4 mmHg; p <0,0001). Dentro de los parámetros de laboratorio, se evidenció un incremento en los valores de glucemia plasmática, con mediana y rango intercuartilo (RIC) de 95 (89-103 mg/dL) vs. 99 (92-107 mg/dL), p <0,0001; y descenso del colesterol HDL (51,8 ± 12,7 mg/dL vs. 49,3 ± 12,8 mg/dL; p <0,00001). No se observaron cambios en el colesterol LDL (116,4 ± 32,6 mg/dL vs. 116,1 ± 34 mg/dL; p = NS), colesterol total (194,9 ± 37,4 vs. 193 ± 39,6 mg/dL; p=NS) o la concentración de triglicéridos, con mediana (RIC) de 114,5 (83,2-162,7 mg/dL) vs 118 (88-169 mg/dL), p=NS. Esto se acompañó de un au mento de la prevalencia de SM (21,5% vs 34%; p<0,0001). También se incrementó la proporción de pac. con placas a nivel carotídeo (35,8% vs. 40,5%; p <0,01). El 18,8% de los pac. incrementaron su peso corporal más del 5%. Esta población estuvo representada por pac. más jóvenes (47,6 ± 14 años vs. 53,3 ± 12 años; p< 0,0001), y se observó correlación inversa entre edad y magnitud del incremento del peso (r =-0,1; p<0,02). Conclusiones : El aislamiento social, durante la pandemia COVID-19, mostró tener importantes consecuencias en los factores de riesgo de la población estudiada. Las implicancias prospectivas de estos hallazgos podrían verse en los próximos años, si estas alteraciones metabólicas no se revierten.


ABSTRACT Background : The COVID-19 pandemic has shocked humanity. During the pandemic, the need for social isolation has encouraged low adherence to a healthy lifestyle in many individuals. However, evidence of the metabolic impact of COVID-19 pandemic on our field is scarce. Objective : To evaluate the impact of social isolation produced by the COVID-19 pandemic on the body weight and the cardio metabolic parameters of an adult population in the Autonomous City of Buenos Aires. Methods : Based on an observational design, we analyzed the data from patients who attended a prevention and health pro motion program in the City of Buenos Aires. Data from participants who attended for testing in 2019 and repeated testing in 2021 were individualized. Medical records were used as source for collecting general data, anthropometric measurements, and laboratory values. The National Cholesterol Education Program (NCEP) criteria were used to define the presence of metabolic syndrome (MS). Results : A total of 558 patients with available evaluations in 2019 and 2021 were identified. The average age of the population was 52.2 ± 12.8 years, and 41% was female. An increase in body weight (82.1 ± 17.7 kg vs. 83.1 ± 18.5 kg; p<0.0001) and body mass index (29.4 ± 5.4 vs. 29.8 ± 5.7, p <0.0001) was observed. Increases in systolic (123.1 ± 15.1 mmHg vs. 126.6 ± 16.3 mmHg; p <0.0001) and diastolic (77.7 ± 9.3 mmHg vs. 79.6 mmHg± 9.4 mmHg, p <0.0001) blood pressure values were also observed. As regards the laboratory parameters, we noted an increase in plasma glucose levels with a median and an interquartile range (IQR) of 95 (89-103 mg/dL) vs. 99 (92-107 mg/dL), p <0.0001, and a decrease in HDL cholesterol (51, 8 ± 12.7 mg/dL vs. 49.3 ± 12.8 mg/dL, p<0.0001). No changes were observed in LDL cholesterol (116.4 ± 32.6 mg/dL vs. 116.1 ± 34 mg/dL; p=NS), total cholesterol (194.9 ± 37.4 vs. 193 ± 39.6 mg/dL; p=NS) or triglyceride levels, with a median and IQR of 114.5 (83.2-162.7 mg/dL) vs. 118 (88-169 mg/dL; p=NS). This was accompanied by an increased prevalence of MS (21.5% vs. 34%; p<0.0001). The proportion of patients with carotid plaques also increased, without reaching statistical significance (36.4% vs. 40.7%; p=NS). Besides, it was observed that 18.8% of the patients increased their body weight by more than 5%. This population was represented by younger patients (47.6 ± 14 years vs. 53.3 ± 12 years; p< 0.0001) showing a reverse correlation between age and scope of weight increase (r=-0.1; p<0.02). Conclusion : Social isolation during the COVID-19 pandemic was shown to have important consequences on the risk factors of the population studied. The prospective implications of these findings might become apparent in the next few years if these metabolic alterations are not reversed.

RESUMO

The CIMAR program (Marine Research Cruises to Remote Areas) run by the Chilean Navy through the National Oceanographic Committee has been developed since 1995, focused on Chilean fjord and channel zones (~41-56°S; "CIMAR-Fjords") and Chilean remote islands ("CIMAR-Islands"). Samples and data was collected on biotic and abiotic variables on all these cruises, both from the water column and benthos. Our work standardizes, compiles, and summarizes the published information on benthic organisms for twenty-one CIMAR-Fjords cruises developed in the first 25 years of the program, plus the Southern Ice Fields Cruise 1995 (precursor of the CIMAR program), which includes the distribution, abundance and geographic location of cruises sampling stations. The data set includes 8,854 records from 880 different localities, corresponding to 1,225 species from 24 different phyla (four kingdoms) and more than 150,000 individuals. Only two cruises did not record any benthic sampling. The fjords and channels of Chilean Patagonia have high biodiversity, so we hope that our data set will serve as a baseline for ecological studies and ecosystem conservation.

RESUMO

Binge Drinking (BD) corresponds to episodes of ingestion of large amounts of ethanol in a short time, typically ≤2 h. BD occurs across all populations, but young and sports-related people are especially vulnerable. However, the short- and long-term effects of episodic BD on skeletal muscle function have been poorly explored. Young rats were randomized into two groups: control and episodic Binge-Like ethanol protocol (BEP) (ethanol 3 g/kg IP, 4 episodes of 2-days ON-2-days OFF paradigm). Muscle function was evaluated two weeks after the last BEP episode. We found that rats exposed to BEP presented decreased muscle strength and increased fatigability, compared with control animals. Furthermore, we observed that skeletal muscle from rats exposed to BEP presented muscle atrophy, evidenced by reduced fiber size and increased expression of atrophic genes. We also observed that BEP induced fibrotic and inflammation markers, accompanied by mislocalization of nNOSµ and high levels of protein nitration. Our findings suggest that episodic binge-like ethanol exposure alters contractile capacity and increases fatigue by mechanisms involving atrophy, fibrosis, and inflammation, which remain for at least two weeks after ethanol clearance. These pathological features are common to several neuromuscular diseases and might affect muscle performance and health in the long term.

RESUMO

INTRODUCTION: It has been reported in different parts of the world that war veterans are more exposed to cardiovascular risk factors. The objective of this study was to establish the risk factors, the cardiometabolic profile and the prevalence of cardiovascular disease in a group of ex-combatants of the Malvinas War (HdeM). METHODS: In a case-control design, data from 799 HdeM were analyzed and compared with 799 controls matched by age. The sample was selected from the participants of the Cardiovascular Health Prevention Program of the Favaloro Foundation, between January 2017 and December 2019. RESULTS: The average age was 56.9 ± 3.9 years. An increase in weight was observed among the HdeM (91.3 ± 16.6 kg vs. 88.2 ± 14.7 kg; p = 0.0001). A higher frequency of arterial hypertension (42% vs. 34%; p < 0.001) and diabetes mellitus (15.1% vs. 10.4%; p < 0.005) was observed in HdeM. Metabolic syndrome was also more prevalent in HdeM (49.2% vs. 39.7%; p = 0.0001). It was observed that the history of acute myocardial infarction was more frequent among the HdeM (3.6% vs. 2%; p < 0.05), with a similar prevalence of stroke (1.2% vs. 1%; p = ns), coronary angioplasty (3.2% vs. 2.1%; p = ns) or myocardial revascularization surgery (0.8% vs. 0.4%; p = ns). DISCUSSION: The HdeM showed an increase in the frequency of risk factors, metabolic syndrome and acute myocardial infarction. It is important to take this increased risk into account in order to maximize cardiovascular prevention strategies in ex-combatants.

Resultados: La edad promedio fue 56.9 ± 3.9 años. Se observó un aumento del peso entre los HdeM (91.3 ± 16.6 kg vs. 88.2 ± 14.7 kg; p = 0.0001). Se observó mayor frecuencia de hipertensión arterial en HdeM (42% vs. 34%; p < 0.001) y diabetes mellitus (15.1% vs. 10.4%; p < 0.005). El síndrome metabólico fue más prevalente en HdeM (49.2% vs. 39.7%; p = 0.0001). Se observó que el antecedente de infarto agudo de miocardio fue más frecuente entre los HdeM (3.6% vs. 2%; p < 0.05), con similar prevalencia de ACV (1.2% vs. 1%; p = ns), angioplastia coronaria (3.2% vs. 2.1%; p = ns) o cirugía de revascularización miocárdica (0.8% vs. 0.4%; p = ns). Discusión: Los HdeM mostraron mayor prevalencia de factores de riesgo, síndrome metabólico e infarto agudo de miocardio. Es importante tener en cuenta este aumento de riesgo para maximizar las estrategias de prevención cardiovascular en los excombatientes.

RESUMO

Background: Chronic alcohol misuse is associated with alcoholic myopathy, characterized by skeletal muscle weakness and atrophy. Moreover, there is evidence that sports-related people seem to exhibit a greater prevalence of problematic alcohol consumption, especially binge drinking (BD), which might not cause alcoholic myopathy but can negatively impact muscle function and amateur and professional athletic performance.Objective: To review the literature concerning the effects of alcohol consumption on skeletal muscle function and structure that can affect muscle performance.Methodology: We examined the currently available literature (PubMed, Google Scholars) to develop a narrative review summarizing the knowledge about the effects of alcohol on skeletal muscle function and exercise performance, obtained from studies in human beings and animal models for problematic alcohol consumption.Results: Exercise- and sport-based studies indicate that alcohol consumption can negatively affect muscle recovery after vigorous exercise, especially in men, while women seem less affected. Clinical studies and pre-clinical laboratory research have led to the knowledge of some of the mechanisms involved in alcohol-related muscle dysfunction, including an imbalance between anabolic and catabolic pathways, reduced regeneration, increased inflammation and fibrosis, and deficiencies in energetic balance and mitochondrial function. These pathological features can appear not only under chronic alcohol misuse but also in other alcohol consumption patterns.Conclusions: Most laboratory-based studies use chronic or acute alcohol exposure, while episodic BD, the most common drinking pattern in amateur and professional athletes, is underrepresented. Nevertheless, alcohol consumption negatively affects skeletal muscle health through different mechanisms, which collectively might contribute to reduced sports performance.

RESUMO

AIM: To describe the safety and efficacy of patterned laser trabeculoplasty (PLT) as an adjunctive treatment in primary open angle glaucoma (POAG) and ocular hypertension (OHT) after 18-month follow-up in Hispanic population. METHODS: A single-center, retrospective study was conducted. All patients with OHT or POAG undergoing PLT from June 2016 to August 2016 were included in the study. Investigated parameters were intraocular pressure (IOP), the number of IOP-lowering medications, best corrected visual acuity (BCVA), laser parameters and postoperative adverse events. Primary efficacy outcome measures were the proportion of eyes achieving an IOP reduction ≥20% at 18mo versus baseline medicated IOP or a reduction in the number of medications while maintaining IOP values. RESULTS: From 40 PLT-treated eyes (mean baseline IOP 20.3±1.7 mm Hg), 24 patients were analyzed (age 63.4±7.3y). The mean IOP reductions from baseline across visits (months 1, 3, 6, 9, 12, and 18) ranged from 14.1% to 20.8%. Success rate after 18-month follow-up was 61.7% with a mean IOP of 16±3.2 mm Hg (P<0.001). The number of glaucoma IOP-lowering medications per eye (preoperative 2.1±1.1 and postoperative 2.3±1.1, P=0.86) and the mean BCVA (preoperative 0.10±0.22 and postoperative 0.11±0.22 logMAR, P=0.42) remained stable. Adverse events comprised transitory IOP spikes in 4 eyes (10%) and peripheral anterior synechiae in 7 eyes (17.5%). CONCLUSION: Mid-term results of PLT show that this procedure may be an efficacious and safe technique to approach medically uncontrolled OHT or POAG patients.

RESUMO

The Cellular Communication Network (CCN) family of matricellular proteins comprises six proteins that share conserved structural features and play numerous biological roles. These proteins can interact with several receptors or soluble proteins, regulating cell signaling pathways in various tissues under physiological and pathological conditions. In the skeletal muscle of mammals, most of the six CCN family members are expressed during embryonic development or in adulthood. Their roles during the adult stage are related to the regulation of muscle mass and regeneration, maintaining vascularization, and the modulation of skeletal muscle fibrosis. This work reviews the CCNs proteins' role in skeletal muscle physiology and disease, focusing on skeletal muscle fibrosis and its regulation by Connective Tissue Growth factor (CCN2/CTGF). Furthermore, we review evidence on the modulation of fibrosis and CCN2/CTGF by the renin-angiotensin system and the kallikrein-kinin system of vasoactive peptides.

RESUMO

OBJECTIVE: Provide a timely, rigorous and continuously updated summary of the evidence on the role of remdesivir in the treatment of patients with COVID-19. METHODS: Eligible studies were randomized trials evaluating the effect of remdesivir versus placebo or no treatment. We conducted searches in the special L·OVE (Living OVerview of Evidence) platform for COVID-19, a system that performs regular searches in databases, trial registries, preprint servers and websites relevant to COVID-19. All the searches covered the period until 25 August 2020. No date or language restrictions were applied. Two reviewers independently evaluated potentially eligible studies according to predefined selection criteria, and extracted data on study characteristics, methods, outcomes, and risk of bias, using a predesigned, standardized form. We performed meta-analyses using random-effect models and assessed overall certainty in evidence using the GRADE approach. A living, web-based version of this review will be openly available during the COVID-19 pandemic. RESULTS: Our search strategy yielded 574 references. Finally, we included three randomized trials evaluating remdesivir in addition to standard care versus standard care alone. The evidence is very uncertain about the effect of remdesivir on mortality (RR 0.7, 95% CI 0.46 to 1.05; very low certainty evidence) and the need for invasive mechanical ventilation (RR 0.69, 95% CI 0.39 to 1.24; very low certainty evidence). On the other hand, remdesivir likely results in a large increase in the incidence of adverse effects in patients with COVID-19 (RR 1.29, 95% CI 0.58 to 2.84; moderate certainty evidence). CONCLUSIONS: The evidence is insufficient for the outcomes critical for making decisions on the role of remdesivir in the treatment of patients with COVID-19, so it is impossible to balance potential benefits, if there are any, with the adverse effects and costs.

RESUMO

OBJECTIVE: To provide a review of the literature on the presence of SARS-CoV-2 in the sexual fluids of patients with COVID-19 and to observe its possible sexual transmission in a timely, rigorous, and continuously updated manner. DATA SOURCES: We will conduct searches in PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), grey literature, and a centralized repository in L·OVE (Living OVerview of Evidence). L·OVE is a platform that maps PICO questions to evidence from the Epistemonikos database. In response to the COVID-19 emergency, L·OVE was adapted to expand the range of evidence it covers and customized to group all COVID-19 evidence in one place. The search will cover the period until the day before submission to a journal. ELIGIBILITY CRITERIA FOR SELECTING STUDIES AND METHODS: We adapted an already published standard protocol for multiple parallel systematic reviews to the specificities of this question. We will include randomized trials evaluating the sexual transmission of the SARS-CoV-2 virus. Randomized trials evaluating the sexual transmission of other coronaviruses, such as MERS-CoV and SARS-CoV, and non-randomized studies in COVID-19 will be searched if no direct evidence from randomized trials is found or if the direct evidence provides a low to a very low level of certainty for critical outcomes. Two reviewers will independently screen each study for eligibility, extract data, and assess the risk of bias. We will perform random-effects meta-analyses and use GRADE to assess the certainty of the evidence for each outcome. A living, web-based version of this review will be openly available during the COVID-19 pandemic. We will resubmit the review if the conclusions change or if there are substantial updates. PROSPERO REGISTRATION: (CRD42020189368).


OBJETIVO: Proporcionar una revisión de la literatura sobre la presencia de SARS-CoV-2 en los fluidos sexuales de pacientes con COVID-19 y su posible transmisión sexual de manera oportuna, rigurosa y continuamente actualizada. FUENTES DE DATOS: Realizaremos búsquedas en PubMed / Medline, Embase, Registro Cochrane Central de Ensayos Controlados (CENTRAL), literatura gris y en un repositorio centralizado en L · OVE (Living OVerview of Evidence). L · OVE es una plataforma que mapea las preguntas PICO a la evidencia de la base de datos Epistemonikos.

RESUMO

OBJETIVO: Esta revisión sistemática viva tiene como objetivo entregar un resumen oportuno, riguroso y continuamente actualizado de la evidencia disponible sobre los efectos de remdesivir en pacientes con COVID-19. MÉTODOS: Se buscaron ensayos aleatorios que evaluaran el uso de remdesivir versus placebo o ningún tratamiento en pacientes con COVID-19. Se realizó una búsqueda en la plataforma L·OVE COVID-19 (Living OVerview of Evidence), un sistema que mantiene búsquedas regulares en bases de datos, registros de ensayos, servidores preprint y sitios web relevantes en COVID-19. Todas las búsquedas fueron realizadas hasta el 25 de agosto de 2020. No se aplicaron restricciones de fecha ni de idioma. Dos revisores evaluaron de forma independiente los artículos potencialmente elegibles, de acuerdo con criterios de selección predefinidos, y extrajeron los datos mediante un formulario estandarizado. Los resultados fueron combinados mediante un metanálisis utilizando modelos de efectos aleatorios y evaluamos la certeza de la evidencia utilizando el método GRADE. Una versión viva de esta revisión estará abiertamente disponible durante la pandemia de COVID-19. RESULTADOS: La búsqueda inicial arrojó 574 referencias. Finalmente, identificamos 3 ensayos aleatorios, que evaluaban el uso de remdesivir adicionado al tratamiento estándar versus tratamiento estándar. La evidencia es muy incierta acerca del efecto del remdesivir sobre la mortalidad (RR 0,7; IC del 95%: 0,46 a 1,05; certeza de la evidencia muy baja) y la necesidad de ventilación mecánica invasiva (RR 0,69; IC del 95%: 0,39 a 1,24; certeza de evidencia muy baja). Por otro lado, es probable que el uso de remdesivir produzca un aumento en la incidencia de efectos adversos en pacientes con COVID-19 (RR 1,29; IC del 95%: 0,58 a 2,84; evidencia de certeza moderada). CONCLUSIONES: La evidencia disponible sobre el papel del remdesivir en el tratamiento de pacientes con COVID-19 es insuficiente en relación a los desenlaces críticos para tomar decisiones, por lo que no es posible realizar un correcto balance entre los beneficios potenciales, los efectos adversos y los costos.


OBJECTIVE: Provide a timely, rigorous and continuously updated summary of the evidence on the role of remdesivir in the treatment of patients with COVID-19. METHODS: Eligible studies were randomized trials evaluating the effect of remdesivir versus placebo or no treatment. We conducted searches in the special L·OVE (Living OVerview of Evidence) platform for COVID-19, a system that performs regular searches in databases, trial registries, preprint servers and websites relevant to COVID-19. All the searches covered the period until 25 August 2020. No date or language restrictions were applied. Two reviewers independently evaluated potentially eligible studies according to predefined selection criteria, and extracted data on study characteristics, methods, outcomes, and risk of bias, using a predesigned, standardized form. We performed meta-analyses using random-effect models and assessed overall certainty in evidence using the GRADE approach. A living, web-based version of this review will be openly available during the COVID-19 pandemic. RESULTS: Our search strategy yielded 574 references. Finally, we included three randomized trials evaluating remdesivir in addition to standard care versus standard care alone. The evidence is very uncertain about the effect of remdesivir on mortality (RR 0.7, 95% CI 0.46 to 1.05; very low certainty evidence) and the need for invasive mechanical ventilation (RR 0.69, 95% CI 0.39 to 1.24; very low certainty evidence). On the other hand, remdesivir likely results in a large increase in the incidence of adverse effects in patients with COVID-19 (RR 1.29, 95% CI 0.58 to 2.84; moderate certainty evidence). CONCLUSIONS: The evidence is insufficient for the outcomes critical for making decisions on the role of remdesivir in the treatment of patients with COVID-19, so it is impossible to balance potential benefits, if there are any, with the adverse effects and costs.

RESUMO

Salmonella enterica serovar Paratyphi B variant Java sequence type 28 is prevalent in poultry and poultry meat. We investigated the evolutionary relatedness between sequence type 28 strains from Europe and Latin America using time-resolved phylogeny and principal component analysis. We sequenced isolates from Colombia, Guatemala, Costa Rica, and the Netherlands and complemented them with publicly available genomes from Europe, Africa, and the Middle East. Phylogenetic time trees and effective population sizes (Ne) showed separate clustering of strains from Latin America and Europe. The separation is estimated to have occurred during the 1980s. Ne of strains increased sharply in Europe around 1995 and in Latin America around 2005. Principal component analysis on noncore genes showed a clear distinction between strains from Europe and Latin America, whereas the plasmid gene content was similar. Regardless of the evolutionary separation, similar features of resistance to ß-lactams and quinolones/fluoroquinolones indicated parallel evolution of antimicrobial resistance in both regions.

RESUMO

Hypoxia refers to the decrease in oxygen tension in the tissues, and the central effector of the hypoxic response is the transcription factor Hypoxia-Inducible Factor α (HIF1-α). Transient hypoxia in acute events, such as exercising or regeneration after damage, play an important role in skeletal muscle physiology and homeostasis. However, sustained activation of hypoxic signaling is a feature of skeletal muscle injury and disease, which can be a consequence of chronic damage but can also increase the severity of the pathology and worsen its outcome. Here, we review evidence that supports the idea that hypoxia and HIF-1α can contribute to the establishment of fibrosis in skeletal muscle through its crosstalk with other profibrotic factors, such as Transforming growth factor ß (TGF-ß), the induction of profibrotic cytokines expression, as is the case of Connective Tissue Growth Factor (CTGF/CCN2), or being the target of the Renin-angiotensin system (RAS).

RESUMO

The use of biological therapies has meant a great improvement in the management of several conditions like autoimmune, neoplastic or others diseases. Although its use has implied significant improvements in the prognosis of these diseases, it is not exempt from complications: infectious diseases as one of them. The objective of this consensus was to evaluate, from an infectious viewpoint, the safeness of the most frequently used biological therapies and give recommendations for the prevention of infections in patients treated with these drugs. These recommendations were based on the highest quality evidence available for the selected biologics. The consensus counts of 2 manuscripts. This second part is a guideline that details these recommendations through screening strategies, prophylactic therapies and vaccines indications for bacterial, mycobacterial, viral, fungal and parasitic infections, both for adults and children.

RESUMO

A 71-year-old woman presented with spontaneous microhyphema in her left eye, causing blurry vision. Bleeding stopped spontaneously shortly after several cycles of digital compression on the upper eyelid, (which were documented in video), and therefore, did not require laser photocoagulation, a possible approach previously explained to the patient. A microhemangioma at the edge of the iris was identified to be the cause of the condition. The hemorrhage did not recur during the follow-up period (9 months).

RESUMO

PURPOSE: To evaluate the endothelial cell loss in patients with iris-claw phakic lenses (Artisan®) in a long-term follow-up. METHODS: We analyzed the medical records of patients who had undergone iris-claw phakic lens implantation and who had at least 5 years of follow-up. RESULTS: We included 67 eyes with myopic errors (follow-up 9.6 ± 3.0 years) and 10 eyes with mixed astigmatism or hyperopic errors (follow-up 8.8 ± 2.5 years). The mean total endothelial density loss at the last follow-up visit was 18.5% ± 17.0% and 10.5% ± 12.3%, respectively. 29.9% of the eyes in the myopic group and 20% in the hyperopic group lost more than 25% of the preoperative endothelial cell density. During the postoperative follow-up period, 60.8% of the eyes in the myopic group and 40% of the eyes in the hyperopic group lost a higher percentage than the expected physiological loss. Two eyes in the myopic group (3.0%) had a final cell density of less than 1200 cells/mm2. None of the variables studied had a statistically significant association with the percentage of annual endothelial loss in the postoperative period. Three phakic lenses were explanted: two by cataract and one by cataract and severe decrease of the endothelial density (862 cells/mm2). CONCLUSIONS: There is a significant endothelial cell loss in a low percentage of the eyes with Artisan® lenses in the long term, and it can decrease to critical levels. Periodic endothelial density evaluations are required for these patients. The selection criteria of surgical candidates could be reevaluated.

RESUMO

Resumen La incorporación de terapias biológicas ha significado un gran avance en el manejo de diversas patologías de origen autoinmune, neoplásico u otros. Si bien su uso ha implicado mejoras significativas en el pronóstico de estas enfermedades, no está exento de complicaciones, entre éstas, las infecciosas. El objetivo de este consenso fue evaluar el perfil de seguridad, desde la mirada infectológica, de las terapias biológicas de uso más frecuente y dar recomendaciones para la prevención de infecciones en pacientes tratados con ellas, basándose en la evidencia de mayor calidad disponible para los biológicos seleccionados. El consenso cuenta de dos manuscritos. Esta segunda parte corresponde a la guía clínica que detalla estas recomendaciones mediante estrategias de cribado, terapias profilácticas e indicación de vacunas, según corresponde, para infecciones bacterianas, y por micobacterias en particular, virus, hongos y parásitos, tanto para adultos como para niños.

RESUMO

Diseño de estudio: Retrospectivo observacional descriptivo. Método: Se recolectaron datos de pacientes con sífilis ocular evaluados en un centro de referencia de oftalmología en Colombia desde marzo de 2015 hasta febrero de 2017. Resultados: Dieciséis pacientes fueron diagnosticados con sífilis ocular durante el período estudiado. Cuatro (25%) pacientes tuvieron afectación de ambos ojos, para un total de 20 ojos. Hubo 11 (68.8%) hombres y 5 (31.3%) mujeres. La edad media de presentación fue de 51.1 años (23-86 años). Cuatro pacientes masculinos estaban coinfectados con VIH. La manifestación más frecuente fue la panuveítis en ocho ojos (40%). Seis pacientes (37.5%) presentaron hallazgos dermatológicos sistémicos. El tratamiento incluyó penicilina cristalina y esteroides sistémicos. El seguimiento medio fue de 16.2 meses (12-21 meses). La agudeza visual media mejoró de 1,01 ± 0,71 logMAR a 0,58 ± 0,64 logMAR después del tratamiento. Conclusión: La sífilis es una causa poco común de infl amación intraocular. Sin embargo, la incidencia ha venido en aumento en los últimos años tanto en pacientes VIH positivo como VIH negativo. La panuveítis es el hallazgo ocular más frecuente. El pronóstico visual es bueno si hay un diagnóstico y tratamiento temprano.


Background: Syphilis is a sexually transmitted disease caused by Treponema pallidum. It can remain dormant in the individual throughout life. The manifestations of ocular involvement are similar to other infl ammatory eye conditions. It is crucial to make an early diagnosis and management in order to avoid complication. Objective: to describe the clinical characteristics and the results of the treatment of patients with ocular syphilis. Study design: observational retrospective study. Method: Retrospective cohort of patients with ocular syphilis evaluated in an ophthalmology reference center in Colombia from March 2015 to February 2017. Results: Sixteen patients were diagnosed with ocular syphilis during the studied period. Four (25%) patients had involvement of both eyes, for a total of 20 eyes. There were 11 (68.8%) men and 5 (31.3%) women. The mean age of presentation was 51.1 years (23-86 years). Four male patients were coinfected with HIV. Th e most frequent manifestation was panuveitis in eight eyes (40%). Six patients (37.5%) presented systemic dermatological fi ndings. Treatment included crystalline penicillin and systemic steroids. The mean follow-up was 16.2 months (12-21 months). The mean visual acuity improved from 1.01 ± 0.71 logMAR to 0.58 ± 0.64 logMAR after treatment. Conclusion: Syphilis is a rare cause of intraocular inflammation. However, the incidence has been increasing in recent years in both HIV positive and HIV negative patients. Panuveitis is the most frequent ocular finding. The visual prognosis is good if there is an early diagnosis and treatment.
