RESUMO Objetivos: Investigar a incidência, fatores de risco e desfechos visuais do desenvolvimento da membrana epirretiniana após reparo do descolamento regmatogênico da retina. Métodos: Trata-se de um estudo retrospectivo de 309 olhos submetidos à cirurgia inicial para descolamento regmatogênico da retina primário sem complicações. Os exames foram realizados no pré-operatório aos 1, 3, 6 e 12 meses pós-operatórios. Os pacientes foram divididos em dois grupos, dependendo da presença ou ausência de membrana epirretiniana. Resultados: A incidência de membrana epirretiniana pós-operatória foi de 28,5%; 42,7% desses pacientes apresentaram desenvolvimento grave da membrana epirretiniana e, portanto, foram submetidos à remoção desta membrana. A regressão logística mostrou que as lágrimas retinianas gigantes (RC: 2,66; 95% IC: 1,045 - 6,792, p=0,040) e lágrimas em ferradura (RC: 0,534; 95% IC: 0,295-0,967, p=0,039), foram preditores significativos de membrana epirretiniana pós-operatória. A coloração com acetonida de triancinolona foi significativamente associada à prevenção da membrana epirretiniana (p=0,022). Trinta e quatro pacientes apresentaram acuidade visual melhorada, ou igual, ou acuidade visual final melhor corrigida; 4 olhos foram avaliados na consulta final de acompanhamento e apresentaram redução da acuidade visual melhor corrigida. Conclusão: Nossa análise demonstra que as lágrimas de ferradura e as lágrimas retinianas gigantes representam fatores de risco para a membrana epirretiniana pós-operatória. A coloração com acetonida de triancinolona teve um efeito preventivo significativo na membrana epirretiniana no pós-operatório. Além disso, uma segunda rodada de vitrectomia pars plana, incluindo remoção da membrana, levou a uma melhora significativa da acuidade visual final melhor corrigida na última consulta de acompanhamento, embora a recuperação tenha sido limitada.

ABSTRACT Purpose: To investigate the incidence, risk factors, and visual outcomes of epiretinal membrane development following rhegmatogenous retinal detachment repair. Methods: This was a retrospective study of 309 eyes that underwent initial surgery for primary uncomplicated rhegmatogenous retinal detachment. Examinations were conducted preoperatively and then postoperatively at 1, 3, 6, and 12 months. The study patients were categorized into two groups depending on the presence or absence of the epiretinal membrane. Results: The incidence of postoperative epiretinal membrane was 28.5%; 42.7% of these patients had severe epiretinal membrane development and therefore underwent the epiretinal membrane removal. Logistic regression analyses revealed that giant retinal tears (OR: 2.66; 95% CI: 1.045-6.792, p=0.040) and horseshoe tears (OR: 0.534; 95% CI: 0.295-0.967, p=0.039) were the significant predictors of postoperative epiretinal membrane. Triamcinolone acetonide staining was significantly associated with the prevention of epiretinal membrane (p=0.022). A total of 34 patients showed a better or an equal final best-corrected visual acuity; of which 4 eyes were evaluated at the final follow-up visit and exhibited a reduced best-corrected visual acuity. Conclusion: Our analysis demonstrated that horseshoe tears and giant retinal tears represent the risk factors for the postoperative epiretinal membrane. Triamcinolone acetonide staining had a significant preventive effect on the postoperative epiretinal membrane. Furthermore, a second round of pars plana vitrectomy, including membrane removal, led to a significant improvement in the final best-corrected visual acuity as per the last follow-up examination, albeit the recovery was limited.

Abstract Observation ECA’s treatment effects in Adjuvant arthritis rats and relative mechanisms. The rat model of arthritis was established by subcutaneous injection of 0.2 mL Freund’s complete adjuvant. After model success, giving different ECA concentrations (25 mg/kg, 50 mg/kg and 100 mg/kg) to rats by ig methods and continued to 28 days. Measuring thymus and spleen index; observation histopathological morphology of rat joint by HE and Masson staining, and Inflammatory cells, synovial hyperplasia, oochas score and degree of fibrosis were detected semi quantitatively. The relative gene and protein expressions were measured by RT-PCR and Western blot. Compared with Normal group, Inflammatory cells, synovial hyperplasia, fibrosis and oochas score increased significantly in Model group (P<0.01, respectively); COX-1, COX-2, TNF-α, IL-1β, IL-6 and IL-17 mRNA expression were significantly up-regulation (P<0.01); AMPK, Beclin1 and ATG12 mRNA and protein expressions were significantly down-regulation (P<0.01, respectively). Compared with Model group, The inflammatory cells, the degree of fibrosis, the proliferation of synovial tissue and OOCHAS score decreased significantly in Middle and High groups (P<0.01, respectively); Thymus index significantly depressed in Low, Middle and High groups (P<0.01, respectively); spleen index were significantly down-regulation in Middle and High groups (P<0.05 or P<0.01); COX-2, TNF-α and IL-17 mRNA expression was significantly down-regulation (P<0.05), IL-1βand IL-6 mRNA expression were significantly depressed in Middle and High groups (P<0.05 or P<0.01); AMPK, Beclin1, LC3-II, ATG5 and ATG7 mRNA expressions were significantly up-regulation in Middle and High groups (P<0.05 or P<0.01); mTOR gene expression was significantly down-regulation (P<0.05), ATG12 mRNA expression was significantly up-regulation (P<0.01) in High group; AMPK, Beclin1, LC3-II, ATG5 and ATG7 protein expressions were significantly increased in High group (P<0.05 or P<0.01), mTOR protein expression were significantly down-regulation and ATG12 protein expression were significantly up-regulation in Low, Middle and High groups (P<0.05 or P<0.01, respectively). ECA can inhibit the inflammatory response in adjuvant arthritis rats, and its mechanism may be related to promoting autophagy of synovial cells.

ABSTRACT Cataract is the leading cause of curable blindness worldwide. It results from opacity of the crystalline lens with gradual, slow and progressive visual acuity reduction. Surgery for removal of the crystalline lens is the only cure for this visual impairment. Phacoemulsification technique has evolved to achieve perfection and the aim of restoring patients' vision with the greatest quality and quantity in the shortest possible time. Scientific development has been aimed at either controlling or eliminating preoperative or surgically induced astigmatism. To achieve this aim, recent inclusion has been made of the use of flexible toric trifocal intraocular lenses and minor incisions at two millimeters in the clear cornea, as well as limbal relaxing incisions, opposite incisions in the clear cornea, photoablative refractive surgery and femtosecond laser. To obtain a good refractive result in cataract surgery it is indispensable to minimize the astigmatism induced by the procedure. Such success is accomplished through an exhaustive personalized preoperative study allowing to meet the visual needs of patients and their early reincorporation to daily activities. Hence the motivation to conduct a search of a variety of papers published in the last ten years with the purpose of describing the principles applied to evaluate mean induced astigmatism after crystalline lens surgery and its effect on the patients' visual acuity and quality of life. Use was made of the Google platform, particularly the Virtual Health Library with all its search engines.

RESUMEN La catarata es la primera causa de ceguera curable en el mundo y se produce por la opacidad del cristalino, con una disminución gradual, lenta y progresiva de la agudeza visual. La cirugía para extraer el cristalino es la única forma de curar esta discapacidad visual. La facoemulsificación ha evolucionado con el fin de lograr su perfección y el objetivo de restablecer la visión de los pacientes con la mayor calidad y cantidad en el menor tiempo posible. El desarrollo científico ha estado encaminado a controlar o eliminar el astigmatismo preoperatorio o inducido por la cirugía, y para esto se ha incluido en la actualidad el empleo de los lentes intraoculares trifocales flexibles tóricos y las incisiones menores a dos milímetros en la córnea clara, así como las incisiones relajantes limbares, las incisiones opuestas en la córnea clara, la cirugía refractiva fotoablativa y el láser de femtosegundo. Para lograr un resultado refractivo en la cirugía de catarata es imprescindible minimizar al máximo el astigmatismo inducido por el procedimiento. Este éxito se logra con un estudio personalizado preoperatorio exhaustivo, que permita satisfacer las necesidades visuales del paciente y su reincorporación temprana a sus tareas. De ahí la motivación para realizar una búsqueda de los últimos diez años de diversos artículos publicados, con el objetivo de describir los principios para evaluar el astigmatismo medio inducido posterior a la cirugía del cristalino, y su repercusión en la calidad visual y de vida de los pacientes. Se utilizó la plataforma google, específicamente la Biblioteca Virtual de Salud, con todos sus buscadores.

ABSTRACT The information obtained by human beings through their eyes is essential for their interaction with the environment. This is the reason why we all consider our sight as our most valuable sense. It is thus easy to understand that any individual undergoing eye surgery will develop a high degree of anxiety. Hence the importance of their cooperation to prevent surgical complications, since on many occasions surgery is performed with local anesthesia. Preventing pain and stopping eye movement are therefore a crucial previous step in surgery. With the application of technological development to ophthalmology, new surgical procedures have emerged aimed at the patients' visual recovery and early social reincorporation. One of those procedures is phacoemulsification cataract surgery, which requires anesthetic methods that make it possible to achieve such an end. Examples of advances in this field are topical anesthesia and cryoanalgesia, both of which are applied at Ramón Pando Ferrer Cuban Institute of Ophthalmology. A search was conducted for papers published on the PubMed platform with the purpose of becoming acquainted with the development and characteristics of the anesthetics used in cataract surgery.

RESUMEN Para el ser humano la información suministrada por sus ojos resulta esencial en su interacción con el entorno. Por esta razón todos consideramos la vista como nuestro sentido más valioso. Es fácil comprender, por tanto, que cualquier individuo sometido a una operación oftalmológica desarrollará un alto grado de ansiedad; de ahí la importancia de su cooperación para evitar las complicaciones quirúrgicas, donde en muchas ocasiones la cirugía se realiza con anestesia local. Es por eso que evitar el dolor y abolir los movimientos oculares va a ser un paso previo fundamental en la cirugía. Con el advenimiento del desarrollo tecnológico aplicado a la Oftalmología, nuevos procedimientos quirúrgicos persiguen una recuperación visual y social temprana de los pacientes. Dentro de ellos la cirugía de catarata por facoemulsificación exige métodos anestésicos que permitan lograr este propósito, y en la actualidad ya podemos mencionar la anestesia tópica y la crioanalgesia como avances en este sentido, las cuales se aplican en el Instituto Cubano de Oftalmología “Ramón Pando Ferrer”. Se realizó una búsqueda de diversos artículos publicados en la plataforma de PubMed, con el objetivo de conocer el desarrollo y las características de los anestésicos aplicados en la cirugía de catarata.

Endoplasmic reticulum (ER) stress is a critical molecular mechanism involved in the pathogenesis of sepsis. Hence, strategies for alleviating this stress may be essential for preventing cardiovascular injuries under sepsis. Adiponectin is secreted by adipocytes and its levels are decreased in sepsis. The purpose of this study was to investigate the protective effects of adiponectin treatment on endothelial cells and its mechanism. Male Wistar rats underwent cecal ligation and puncture (CLP) before being treated with adiponectin (72 and 120 μg/kg). The levels of malondialdehyde (MDA) in plasma, histological structure, and apoptosis of endothelial cells were evaluated. In vitro, human umbilical vein endothelial cells (HUVECs) were treated with adiponectin at 10 and 20 μg/mL for 24 h after stimulation by lipopolysaccharide (LPS). The levels of reactive oxygen species (ROS), ultrastructure, rate of apoptosis, the expression of inositol-requiring enzyme 1α (IRE1α) protein, and its downstream molecules (78 kDa glucose-regulated protein (GRP78), C/EBP homologous protein (CHOP), and caspase-12) were detected. The results showed that the levels of MDA and ROS induced by CLP or LPS stimulation were increased. Furthermore, endothelial cell apoptosis was increased under sepsis. The IRE1α pathway was initiated, as evidenced by activated IRE1α, increased GRP78, and up-regulated CHOP and caspase-12 in HUVECs. Following treatment with adiponectin, the number of apoptotic endothelial cells was markedly decreased. These findings demonstrated that treatment with adiponectin decreased apoptosis of endothelial cells caused by sepsis by attenuating the ER stress IRE1α pathway activated by oxidative stress.

RESUMO Objetivo Descrever a relação entre a exposição à violência doméstica física e/ou sexual praticada pelo parceiro íntimo e os indicadores de utilização de serviços de atenção pré-natal entre mulheres hondurenhas em idade reprodutiva. Métodos Foram analisados dados da Pesquisa de Demografia e Saúde 2011–2012 de Honduras para descrever a relação entre a exposição à violência doméstica praticada pelo parceiro íntimo e dois desfechos da atenção pré-natal: (1) consultas de atenção pré-natal em número adequado (definido pelo Ministério da Saúde hondurenho como cinco ou mais consultas) e (2) início precoce da atenção pré-natal (no primeiro trimestre). Foi usada regressão logística múltipla para estimar os efeitos da violência doméstica física e sexual nos desfechos após controlar para idade, nível de escolaridade, alfabetismo, local de domicílio, tamanho da família, paridade e renda da mulher e idade e nível de escolaridade do parceiro. Resultados Dentre as mulheres casadas, com pelo menos um filho vivo com até 5 anos de idade e que responderam o módulo de violência doméstica (N = 6.629), 13,5% informaram violência física e 4,1% informaram violência física e sexual. Não houve associação significativa entre a violência doméstica e o início precoce da atenção pré-natal, porém se verificou uma relação significativa entre a violência doméstica e um número adequado de consultas no pré-natal. As mulheres que vivenciaram violência doméstica física (odds ratio ajustado [aOR] 1,25; intervalo de confiança de 95% [IC 95%] 1.00–1.56) ou sexual (aOR 1,53; IC 95% 1,08–2,16) apresentaram uma chance 25% e 53% maior, respectivamente, de ter atenção pré-natal inadequada. Conclusões Honduras tem uma de taxas mais elevadas de violência interpessoal de todo o mundo. A violência doméstica praticada pelo parceiro íntimo no país é um fator contribuinte à categoria mais ampla de violência interpessoal e constitui um fator de risco para atenção pré-natal inadequada. Os nossos resultados indicam que o rastreamento universal da violência doméstica na atenção pré-natal, aliado a iniciativas futuras para reduzir este tipo de violência, poderia melhorar a utilização de serviços de atenção pré-natal no país.

ABSTRACT Objective To describe the relationship between exposure to physical and/or sexual intimate partner violence (IPV) and indicators of antenatal care (ANC) service utilization among Honduran women of reproductive age. Methods Data from the 2011-2012 Honduras Demographic and Health Survey were analyzed to describe the relationship between self-reported exposure to IPV and two ANC outcomes: (1) sufficient ANC visits (defined by the Honduran Ministry of Health as five or more visits) and (2) early ANC initiation (within the first trimester). Multiple logistic regression was used to estimate effects of physical and sexual IPV on the outcomes, controlling for women’s age, education, literacy, residence, household size, religion, parity, wealth, husband’s age, and husband’s education. Results Of women who were married, had at least one living child 5 years or younger, and completed the IPV module (N = 6 629), 13.5% of them reported any physical IPV, and 4.1% reported both physical and sexual IPV. There was no significant association between IPV and early ANC; however, a significant relationship between IPV and sufficient ANC was found. Women who experienced any physical IPV (adjusted odds ratios (aOR) = 1.25; 95% confidence interval (CI): 1.00-1.56) or sexual IPV (aOR = 1.53; 95% CI: 1.08-2.16) were, respectively, 25% and 53% more likely to receive insufficient ANC. Conclusions Honduras has one of highest rates of interpersonal violence of any nation in the world. In Honduras, IPV is a contributor to this broader category of interpersonal violence as well as a risk factor for insufficient ANC. Our findings suggest that universal IPV screening during ANC as well as future initiatives aimed at reducing IPV might improve ANC utilization in the country.

RESUMEN Objetivo El presente estudio tuvo por objeto describir la relación entre la exposición a la violencia física o sexual infligida por la pareja y los indicadores de utilización de los servicios de control prenatal por las mujeres hondureñas en edad fecunda. Métodos Se analizaron los datos de la Encuesta de Demografía y Salud del 2011-2012 de Honduras con el fin de describir la relación entre la exposición autonotificada a la violencia de pareja y dos resultados de la atención prenatal, a saber: 1) un número suficiente de consultas de control prenatal (definido como cinco o más por el Ministerio de Salud hondureño) y 2) el inicio temprano del control prenatal (durante el primer trimestre del embarazo). Se aplicó un modelo de regresión logística multivariante a fin de calcular los efectos de la violencia de pareja tanto física como sexual en los indicadores, tras ajustar con respecto a la edad de la mujer, la escolaridad, el alfabetismo, el lugar de residencia, el tamaño del hogar, la religión, el número de partos, el nivel de riqueza, la edad de la pareja y su escolaridad. Resultados De las mujeres casadas, que tenían por lo menos un hijo vivo de 5 años o menor y que completaron el módulo de violencia de pareja de la encuesta (n = 6 629), 13,5% refirieron algún tipo de violencia física y 4,1% notificaron violencia física y sexual infligida por la pareja. No se observó una relación estadísticamente significativa entre la violencia de pareja y el control prenatal temprano; sin embargo, se encontró una asociación significativa entre la violencia de pareja y el número suficiente de consultas de control prenatal. La probabilidad de recibir una atención prenatal insuficiente fue mayor en las mujeres que sufrieron algún tipo de violencia de pareja y, en el caso de la violencia física, fue de 25% (razón de posibilidades ajustadas [ORa]) = 1,25; intervalo de confianza de 95% [IC]: 1,00-1,56) y de la violencia sexual fue 53% (ORa = 1,53; IC de 95%: 1,08-2,16). Conclusiones Honduras tiene una de las tasas más altas de violencia interpersonal de todos los países del mundo. En este país, la violencia de pareja es un factor que contribuye a la categoría más amplia de la violencia interpersonal y representa además un factor de riesgo de tener un control prenatal insuficiente. Los resultados del presente estudio indican que la detección sistemática universal de la violencia de pareja en el marco de la atención prenatal y las iniciativas futuras encaminadas a reducir este tipo de violencia podrían mejorar la utilización del control prenatal en el país.
