ABSTRACT

Dentro de las malformaciones congénitas, las cardiopatías son las anomalías más frecuentes y se asocian a una elevada morbimortalidad perinatal y a largo plazo. El objetivo de esta actualización es revisar la tasa de detección prenatal, las características del tamizaje a lo largo del embarazo, tanto en el primero como en el segundo trimestre, las indicaciones de ecocardiografía avanzada, y establecer un algoritmo de manejo ante el diagnóstico prenatal de una cardiopatía congénita. Se discutirán los estudios invasivos y no invasivos que pueden realizarse y el seguimiento obstétrico. Finalmente, se revisarán las características principales de la terapia fetal en anomalías cardíacas, tanto intervencionismo cardíaco como el tratamiento intrauterino de las arritmias.


Among congenital malformations, heart defects are the most common type of anomaly, and these are associated with a high perinatal, long-term morbidity and mortality. The objective of this update was to review the rate of prenatal detection, screening characteristics throughout the pregnancy, in both the first and second trimesters, indications for advanced echocardiography, and to establish a management algorithm in case of prenatal diagnosis of a congenital heart disease. Potential invasive and non-invasive tests and obstetric follow-up will be discussed here. Finally, the main characteristics of fetal therapy in heart anomalies will be reviewed, both cardiac interventions and intrauterine treatment of arrhythmias.

ABSTRACT

Durante el tratamiento del conducto se pueden producir complicaciones como las perforaciones a diferentes niveles, y la más común es la de furca, asociada con la apertura cameral. No obstante, en la actualidad, los cementos bio cerámicos permiten obtener un mejor pronóstico. Se presenta el caso de un primer molar inferior derecho con perforación de furca, el cual fue sellado con Biodentine®. (AU)


During the root canal treatment procedure, complications such as perforations at different levels may occur, the most common being furcal perforation associated with the cameral opening. However, the bioceramic cements currently available can provide better outcomes. We present a case of a right lower first molar with furcation, which was sealed with Biodentine®. (AU)

ABSTRACT

Las enfermedades granulomatosas incluyen una amplia gama de enfermedades. Sin embargo, en la práctica clínica, muchos casos de enfermedad granulomatosa permanecen sin etiología después del examen histológico. Nuestro objetivo fue determinar, a partir de las biopsias de pulmón, pleura y ganglios linfáticos mediastínicos, en los que se informaron granulomas, las características clínicas y los diagnósticos de estos pacientes. Así también la mortalidad a un año de seguimiento. Metodología: Analizamos retrospectivamente biopsias de pulmón, pleura y/o ganglios linfáticos mediastínicos con granulomas de 75 pacientes del Instituto Nacional del Tórax (2012-2016), sus características clínicas y de laboratorio. La información se obtuvo de los registros médicos. Los datos de mortalidad se obtuvieron del registro civil. Resultados: Se determinó una etiología en todos los casos, excepto en 3 (4%). Los diagnósticos más frecuentes fueron tuberculosis (n = 37; 49%) y sarcoidosis (n = 18; 24%). Otras causas fueron silicosis (5,3%), vasculitis (4%) y neumonitis por hipersensibilidad (2,7%). Los pacientes con tuberculosis (TB) tenían parámetros inflamatorios más altos, como velocidad de eritrosedimentación y proteína C reactiva. Además, sólo se encontraron granulomas con necrosis caseosa en pacientes con tuberculosis. En cambio, los pacientes con sarcoidosis tenían lesiones cutáneas y una mayor frecuencia de linfadenopatías. Cuatro (5.3%) pacientes fallecieron a un año de seguimiento: dos debido a neumonía, uno por hipersensibilidad crónica y uno por TB. Conclusión: La tuberculosis y la sarcoidosis fueron las causas más frecuentes de granulomas respiratorios en este estudio retrospectivo. Se logró determinar una etiología en el 96% de los casos, considerando variables clínicas, de laboratorio e histopatológicas para un diagnóstico diferencial correcto.


Granulomatous diseases comprise a wide range of pathologies. However, in clinical practice, many pulmonary granulomas remain without etiology after the histologic examination. Our aim was to determine from the biopsies of the lung, pleura and mediastinal lymph nodes in which granulomas were reported, the clinical characteristics and diagnoses of the patients. Methodology: We analyzed retrospectively biopsies of the lung, pleura and mediastinal lymph nodes with granulomas from 75 patients handled at our institution (2012-2016), as well as their clinical and laboratory data. The information was obtained from medical records. A one-year mortality date was obtained from the civil registry. Main results: A cause was determined in all the cases, except in three of them (4%). The most frequent diagnoses were tuberculosis (n =37; 49%) and sarcoidosis (n =18; 24%). Other causes were silicosis (5.3%), vasculitis (4%) and hypersensitivity pneumonitis (2.7%). Patients with tuberculosis (TB) had higher inflammatory parameters such as erythrocyte sedimentation rate and C-reactive protein. Besides granulomas with caseous necrosis were only found in TB patients. Instead, patients with sarcoidosis had skin lesions and a higher frequency of lymphadenopathy. Four patients (5.3%) died in a one-year of follow-up: two of them because of pneumonia and the other two patients because of chronic hypersensitivity and TB respectively. Conclusion: Tuberculosis and sarcoidosis were the most common causes of respiratory granulomas in this retrospective study. A specific cause was determined in 96% of cases, considering clinical, laboratory and histopathological variables to do a right differential diagnosis.

ABSTRACT

Introducción: El budding tumor (BT) es la presencia de células tumorales aisladas o en pequeños grupos situadas en el frente de invasión del tumor. Su hallazgo en alto grado es un factor de mal pronóstico independiente del cáncer colorrectal. El objetivo de este trabajo es determinar si el grado de BT está asociado con otros factores pronósticos del cáncer rectal. Material y métodos: Se incluyen las resecciones oncológicas de recto en el período 2013-2017. Los casos se agruparon según la densidad en la formación de los BT en 3 grupos, los de grado bajo, intermedio y alto. Se utilizó como valor estadístico el cálculo del odds ratio (OR). Resultados: Se analizaron las piezas de resección de 27 pacientes (15 mujeres y 12 hombres) con una media de edad de 68,4 años (40-86). Se calculó el OR para invasión ganglionar, vascular y recidiva en función del grado de budding tumoral. Discusión: Se observó una tendencia a la presencia de factores histológicos de mal pronóstico en relación al budding de alto grado, si bien el bajo número de casos no permitió demostrarlo en este estudio. Conclusiones: El análisis del grado de tumor budding es reproducible y podría ayudar a identificar pacientes con cáncer rectal de peor pronóstico. (AU)


Introduction: Tumor budding (BT) is defined as isolated or small groups of neoplastic cells located at the invasive front of the tumor. High-grade BT is a poor prognostic factor in colorectal cancer. Objective: To determine if the degree of BT is associated with other prognostic factors in rectal cancer. Materials and methods: Rectal oncological resections during the 2013-2017 period were included. Cases were stratified according to the density in the formation of BT in 3 groups: low, intermediate and high. The calculation of the odds ratio (OR) was used as a statistical value. Results: The resection specimens of 27 patients (15 women and 12 men) with a mean age of 68.4 years (40-86) were analyzed. OR for node metastases, vascular invasion and relapse was calculated according to tumor budding grade. Discussion: High-grade tumor budding seems to associate with the presence of poor prognostic factors. However, it was not possible to demonstrate it because of the small sample size. Conclusions: Tumor budding is a reproducible marker and could help to identify rectal cancer patients with a worse prognosis. (AU)

ABSTRACT

El objetivo de este trabajo fue determinar la relación entre el pronóstico visual según el Ocular Trauma Score (OTS) y la agudeza visual (AV) a los 6 meses de ocurrido el trauma ocular, en pacientes atendidos en la Unidad de Trauma Ocular del Hospital del Salvador, Santiago de Chile. Se hizo uso de un estudio descriptivo, longitudinal, retrospectivo. Se accedió a los registros clínicos de pacientes atendidos por trauma ocular grave entre el 1 de enero de 2014 al 15 de marzo 2015. 145 pacientes conformaron una muestra de 153 ojos. Se estableció la relación entre OTS obtenido y la AV a 6 meses del trauma mediante el coeficiente de correlación de Spearman. De los ojos estudiados, el grupo mayor N=68 (44,4%) calificó para OTS 3 y el menor N=16 (10,5%) para OTS 1. Se presentaron cinco categorías de visión, en un tiempo inicial la mayoría de los casos presentaron AV de luz, mala proyección-cuenta dedos (n=89). Tras seis meses dicha distribución se desplazó hacia la categoría 20/40 - 20/20 (n=68). Se encontró una fuerte asociación (r=0,711 p=0,000) entre el OTS calculado y la AV luego de seis meses de seguimiento. El OTS demostró poseer un gran valor predictivo y es una herramienta aplicable en nuestro medio, los datos obtenidos indican que existe un mejor pronóstico visual que los obtenidos en otro estudio. Cabe destacar que es la primera instancia en que se evalúa la aplicación del OTS en Chile.


This work aimed to determine the relationship between the visual prognosis according to the Ocular Trauma Score (OTS) and visual acuity (AV) 6 months after the ocular trauma in patients treated at the Eye Trauma Unit from the Hospital del Salvador, in Santiago, Chile. A descriptive, longitudinal and retrospective study was performed. We accessed registers of clinical patients attended for severe eye trauma from 1 January 2014 to 15 March 2015. 145 patients constitute a sample of 153 eyes. A connection was established between the OTS obtained and the AV 6 months after the trauma via the Spearman correlation coefficient. From the eyes studied, the greatest group N=68 (44.4%) qualified for OTS 3 and the smallest N=16 (10.5%) for OTS 1. Five eye categories were presented, in the beginning, most of the cases presented visual acuity with bad projection ­ hand motion (n=89). After six months of distribution, it moved to the category 20/40 ­ 20/20 (n=68). A strong relation (r=0,711 p=0,000) was found between the estimated OTS and the AV after six months of tracking. The OTS proved to have great predictive valor and is an applicable tool in our area, the data obtained showed that there is a better visual prognosis than the obtained in other studies. It is worth noting that this is the first stage where the application of OTS is assessed in Chile.

ABSTRACT

El Tumor de Wilms (TW) es el tumor renal más frecuente entre los 1 y 5 años de edad. La evidencia existente respecto de aspectos clínicos, terapéuticos y de supervivencia (SV) del TW es escasa. El objetivo de este estudio fue determinar diferencias en la SV actuarial global (SVAG) y SV libre de enfermedad (SVLE) a 5 años en pacientes con TW tratados con quimioterapia neoadyuvante (QTNA) y cirugía inicial (CI). Serie de casos. Se incluyeron pacientes con TW de 11 meses y 13 años de edad, tratados en el Instituto del Cáncer SOLCA, Cuenca (1994-2019). Las variables resultado fueron SVAG y SVLE a 5 años. Otras variables de interés fueron: localización, estadio, histología, seguimiento y remisión completa (RC). Una vez concluidos sus tratamientos, los pacientes fueron sometidos a un seguimiento clínico. Se utilizó estadística descriptiva (medidas de tendencia central y dispersión) y analítica (Chi2, exacto de Fisher y corrección por continuidad). Se realizaron análisis de SV con curvas de Kaplan Meier y log-rank. Se reclutaron 36 pacientes (52,8 % hombres), con una mediana de edad de 44 meses; 55,5 % de ellos tuvieron histología favorable. La localización y estadio más frecuente fue riñón izquierdo (55,5 %) y I (33,3 %) respectivamente. El 58,3 % fueron sometidos a CI y el 41,7 % QTNA. Luego de aplicados los tratamientos 21 pacientes (58,3 %), alcanzaron RC. La SVAG y SVLE general a 5 años fue 72,0 % y 69,0 % respectivamente. Al comparar los subgrupos con QTNA y CI; se verificaron SVAG y SVLE a 5 años de 60,0 % y 81,0 % (p=0,118); y de 66,7 % y 71,4 % (p=0,536) respectivamente. La SVAG y SVLE verificadas son similares a las reportadas en otros estudios. No se evidenciaron diferencias de éstas con los tratamientos QTNA y CI.


Wilms tumor (WT) is the most common pediatric kidney tumor between 1 and 5 years of age. The existing evidence regarding clinical, therapeutic and survival (SV) aspects of TW is scarce. The aim of this study was to determine differences in 5-year overall survival (OS) and 5-year disease-free survival (DFS), in patients treated by WT with neoadjuvant chemotherapy (NACT) and initial surgery (IS). Case series. Patients with TW between 11 months and 13 years of age, treated at SOLCA Cancer Institute, Cuenca, Ecuador (1994-2019) were included. The outcome variables were OS and DFS. Once their treatments were completed, patients were followed clinically. Descriptive (measures of central tendency and dispersion) and analytical (Chi2, Fisher's exact and continuity correction) statistics were applied. SV analysis with Kaplan Meier curves and log-rank were performed. 36 patients (52.8 % men), with a median age of 44 months; 55.5 % of which had favorable histology were recruited. The most frequent location and stage was left kidney (55.5 %) and I (33.3 %) respectively. 58.3 % underwent IC and 41.7 % QTNA. After treatments, 21 patients (58.3 %) achieved complete remission. General OS and DFS were 72.0 % and 69.0 % respectively. When comparing subgroups with QTNA and CI. When comparing the subgroups with QTNA and CI, OS and DFS of 60.0 % and 81.0 % were verified (p=0.118); and of 66.7 % and 71.4 % (p=0.536) respectively. General OS and DFS observed are similar to those reported in other studies. No differences were evidenced with QTNA and CI treatments.

ABSTRACT

Objective: German psychiatrist Kurt Schneider proposed the concept of first-rank symptoms (FRS) of schizophrenia in 1959. However, their relevance for diagnosis and prediction of treatment response are still unclear. Most studies have investigated FRS in chronic or medicated patients. The present study sought to evaluate whether FRS predict remission, response, or improvement in functionality in antipsychotic-naive first-episode psychosis. Methods: Follow-up study of 100 patients at first episode of psychosis (FEP), with no previous treatment, assessed at baseline and after 2 months of treatment. The participants were evaluated with the standardized Positive and Negative Syndrome Scale (PANSS) and Global Assessment of Functioning (GAF) and for presence of FRS. Results: Logistic regression analysis showed that, in this sample, up to three individual FRS predicted remission: voices arguing, voices commenting on one's actions, and thought broadcasting. Conclusion: Specific FRS may predict remission after treatment in FEP patients. This finding could give new importance to Kurt Schneider's classic work by contributing to future updates of diagnostic protocols and improving estimation of prognosis.

ABSTRACT

Objetivo. Describir las características epidemiológicas, el seguimiento hospitalario y la evolución de los pacientes intervenidos por atresia esofágica y su repercusión en la función pulmonar. Población y métodos. Estudio retrospectivo, longitudinal y analítico. Se revisaron las historias clínicas de pacientes con atresia esofágica nacidos entre 1996 y 2017. Se registraron datos perinatales, tipo de atresia, malformaciones asociadas, complicaciones respiratorias y digestivas, y los datos espirométricos durante tres años. Resultados. Se incluyeron 97 pacientes. El tipo de atresia más frecuente fue el III y el síndrome más frecuente, la trisomía 21. El 13,4 % fallecieron en el período neonatal. El 23,8 % de los pacientes estuvo en seguimiento por Neumología y presentó como complicaciones respiratorias exacerbaciones (el 46,4 %), sibilancias o asma (el 36 %), neumonías (el 26,8 %). El reflujo gastroesofágico fue factor de riesgo de sibilancias (OR 5,31; p = 0,002), exacerbaciones (OR 4,00; p = 0,009) y neumonías (OR 3,24; p = 0,02). En la primera espirometría (n = 20), un 65 % presentaba patrón normal; un 30 %, restrictivo, y un 5 %, mixto. En la segunda espirometría (n = 19), un 42,1 % presentaba patrón normal; un 31,6 %, restrictivo; un 15,8 %, obstructivo, y un 10,5 %, mixto. En la tercera espirometría (n = 14), el 50 % presentaba un patrón espirométrico normal; el 21,4 %, restrictivo; el 14,3 %, obstructivo, y un 14,3 %, mixto. Conclusiones. En nuestra muestra de pacientes, una importante proporción presentó comorbilidades respiratorias y digestivas. La función pulmonar empeoró progresivamente.


Objective. To describe the epidemiological characteristics, hospital follow-up, and course of patients who underwent surgery for esophageal atresia and its consequences on lung function. Population and methods. Retrospective, longitudinal, and analytical study. The medical records of patients with esophageal atresia born between 1996 and 2017 were reviewed. Perinatal data, type of atresia, associated malformations, respiratory and gastrointestinal complications, and spirometry data were recorded over 3 years. Results. A total of 97 patients were included. The most common type of atresia was III, and the most frequent syndrome, trisomy 21; 13.4 % of patients died in the neonatal period; 23.8 % were followed up by the Department of Pulmonology, and their respiratory complications included exacerbations (46.4 %), wheezing or asthma (36 %), and pneumonia (26.8 %). Gastroesophageal reflux was a risk factor for wheezing (OR: 5.31; p = 0.002), exacerbations (OR: 4.00; p = 0.009), and pneumonia (OR: 3.24; p = 0.02). In the first spirometry (n = 20), the pattern was normal in 65 %; restrictive in 30 %; and mixed in 5 %. In the second spirometry (n = 19), the pattern was normal in 42.1 %; restrictive in 31.6 %; obstructive in 15.8 %, and mixed in 10.5 %. In the third spirometry (n = 14), the pattern was normal in 50 %; restrictive in 21.4 %; obstructive in 14.3 %, and mixed in 14.3 %.Conclusions. In our sample of patients, a large proportion had respiratory and gastrointestinal comorbidities. Lung function worsened progressively.

ABSTRACT

Adrenal masses are mainly detected unexpectedly by an imaging study performed for reasons unrelated to any suspect of adrenal diseases. Such masses are commonly defined as “adrenal incidentalomas” and represent a public health challenge because they are increasingly recognized in current medical practice. Management of adrenal incidentalomas is currently matter of debate. Although there is consensus on the need of a multidisciplinary expert team evaluation and surgical approach in patients with significant hormonal excess and/or radiological findings suspicious of malignancy demonstrated at the diagnosis or during follow-up, the inconsistency between official guidelines and the consequent diffuse uncertainty on management of small adrenal incidentalomas still represents a considerable problem in terms of clinical choices in real practice. The aim of the present work is to review the proposed strategies on how to manage patients with adrenal incidentalomas that are not candidates to immediate surgery. The recent European Society of Endocrinology/European Network for the Study of Adrenal Tumors guidelines have supported the view to avoid surveillance in patients with clear benign adrenal lesions <4 cm and/or without any hormonal secretion; however, newer prospective studies are needed to confirm safety of this strategy, in particular in younger patients.

ABSTRACT

PURPOSE: Immunological mechanisms underlying asthma exacerbation have not been elucidated. The aim of this study was to assess the associations of various asthma exacerbation traits with selected serum microRNA (miRNA) expression and T-cell subpopulations. METHODS: Twenty-one asthmatics were studied during asthma exacerbation (exacerbation visit [EV] and the follow-up visit [FV] at 6 weeks). At both visits, spirometry was performed, fractional exhaled nitric oxide (FeNO) was measured, and nasopharyngeal and blood samples were collected. In nasopharyngeal samples, respiratory viruses were assayed by multiplex polymerase chain reaction (PCR), and bacterial cultures were performed. Serum miRNAs were assayed with real-time PCR. T-cell surface markers, eosinophil progenitors and intracellular cytokines were assessed by flow cytometry. RESULTS: Two-thirds of patients had moderate or severe exacerbation and the FV, overall improvement in asthma control was observed. The mean expression of serum miRNA-126a, miRNA-16 and miRNA-21 was significantly lower at the EV than at the FV. At EV, miRNA-29b correlated with FeNO (r = 0.44, P < 0.05), and 5 of 7 miRNA tested correlated with pulmonary function tests. The number of cluster of differentiation (CD)45+CD4+interleukin (IL)4+ cells was significantly higher at the EV than at the FV, and positive correlations of T-regulatory cells and eosinophil progenitors with asthma control was found. At the EV, serum miRNAs negatively correlated with the number of T cells expressing IL-4, IL-17, IL-22 and interferon gamma, while at the FV both positive and negative correlations with T-cell subsets were observed. No association of detected pathogen (viruses and bacteria) in nasopharyngeal fluid with clinical, functional and immunological parameters was found. CONCLUSIONS: Epigenetic dysregulation during asthma exacerbation could be related to respiratory function, airway inflammation and T-cell cytokine expression.

ABSTRACT

PURPOSE: Metabolic syndrome (MetS) is a major public health problem related to increased risks of cardiovascular disease and type 2 diabetes. We investigated whether recommended levels of leisure time physical activity (LTPA) decrease the risk of MetS in a community-based prospective cohort study (Ansung and Ansan cohort).MATERIALS AND METHODS: A total of 3910 adults (1890 men, 2020 women) without MetS examined in 2001–2002 (baseline) were included in this study and followed up from 2013 to 2014. We measured LTPA energy expenditure using the standard metabolic equivalent value [metabolic equivalent of task (MET)-h/wk]. Individuals were categorized into five groups (physically inactive, 0.1 to <7.5, 7.5 to <15.0, 15.0 to <22.5, 22.5 to <40.0, and ≥40.0 MET-h/wk).RESULTS: The mean follow-up period was 11.8 years. Among the cohort, 482 men (25.5%) and 541 women (26.8%) were diagnosed with newly developed MetS. Multivariate logistic analysis revealed a 4.4% lower MetS risk among those performing two to three times the recommended minimum of 7.5 MET-h/wk [multivariate relative risk (RR), 0.956; 95% confidence interval (CI), 0.654–1.398] and a 21.9% lower risk among those performing three to four times the physical activity minimum (multivariate RR, 0.781; 95% CI, 0.574–1.063). This association was only significant in females performing three to four times the minimum (crude RR, 0.655; 95% CI, 0.432–0.994).CONCLUSION: We noted that physical activity at more than 2 times the recommended minimum prevents MetS. Healthcare professionals should encourage inactive adults to be physically active during their leisure time to take advantage of its health benefits.

ABSTRACT

PURPOSE: The study aimed to assess the average time to return to play following surgery for chronic lateral ankle instability in athletes.METHODS: A literature search was conducted (1976 to 2019) by two independent reviewers using the Medline, Embase, and Cochrane library databases. Articles were retrieved by an electronic search using individual keywords (“lateral ankle instability,” “surgery,” “operation,” “return to sport,” “return to play”) and their combinations. Studies that met the inclusion criteria were assessed for pertinent data.RESULTS: Six randomized controlled trials were included in this analysis. The mean follow-up period was 44.8 months (range, 31.8–58.1 months) in 219 patients (male, 126; female, 113). The mean age was 23.2 years (range, 18.2–28.2 years). Different criteria for returning to sports were used in each paper. In the papers included in this study, different methods and definitions were used for the postoperative recovery method for lateral ankle instability injury. The average time until return to play was 16.53 weeks.CONCLUSION: There are limitations to the application of different surgical techniques and data from different athletes for chronic lateral ankle instability. However, these results suggest that sports physicians evaluate the surgical outcome and may be utilized as reference data for informing the athletes about their time until return.

ABSTRACT

PURPOSE: Alpha-1 antitrypsin deficiency (A1ATD) in one of the most common genetic causes of liver disease in children. We aimed to analyze the clinical characteristics and outcomes of patients with A1ATD.METHODS: This study included patients with A1ATD from five pediatric hepatology units. Demographics, clinical findings, genetics, and outcome of the patients were recorded (n=25).RESULTS: Eight patients (32.0%) had homozygous PiZZ genotype while 17 (68.0%) had heterozygous genotype. Patients with PiZZ genotype had lower alpha-1 antitrypsin levels than patients with PiMZ genotype (37.6±7.7 mg/dL vs. 66.5±22.7 mg/dL, p=0.0001). Patients with PiZZ genotype were diagnosed earlier than patients with PiMZ genotype, but this was not significant (13±6.8 months vs. 23.7±30.1 months, p=0.192). Follow-up revealed the death of one patient (12.5%) with a homozygous mutation, and revealed that one patient had child A cirrhosis, five patients (62.5%) had chronic hepatitis, and one patient (12.5%) was asymptomatic. Nine of the 17 patients with a heterozygous mutation had chronic hepatitis (52.9%), two (11.7%) had child A cirrhosis, and six (35.2%) were asymptomatic. Overall, 18 (72%) of the 25 children had liver pathology in the long-term.CONCLUSION: Although prevalence is rare, patients with liver disorders should be checked for alpha-1 antitrypsin levels. Moreover, long-term follow-up is essential because most patients have a liver pathology.

ABSTRACT

OBJECTIVES: This study examined the association of the total diet quality with the incidence risk of metabolic syndrome constituents and metabolic syndrome among Korean adults.METHODS: Based on a community-based cohort of the Korean Genome and Epidemiology Study (KoGES) from 2001 to 2014, data from a total of 5,549 subjects (2,805 men & 2,744 women) aged 40~69 years at the baseline with a total follow-up period of 38,166 person-years were analyzed. The criteria of the National Cholesterol Education Program Adult Treatment Panel was employed to define metabolic syndrome. The total diet quality was estimated using the Korean Healthy Eating Index (KHEI). Hazard ratios (HR) and 95% confidence intervals (CI) for risk of metabolic syndrome constituents and metabolic syndrome in relation to KHEI quintile groups was calculated by multivariate Cox proportional hazards regression model.RESULTS: After adjusting for age, energy intake, income, education, physical activity, smoking, and drinking, the incidence of abdominal obesity and high blood pressure was significantly lower, by approximately 29.7% (P < 0.01) and 25.2% (P < 0.01), respectively, in the fifth KHEI quintile compared to the first quintile in men. A significant decreasing trend of the metabolic syndrome incidence was observed across the improving levels of KHEI (HRq5vs.q1: 0.775, 95% CIq5vs.q1: 0.619~0.971, P for trend < 0.01). In women, the incidence of abdominal obesity and metabolic syndrome was significantly lower, by approximately 29.8% (P < 0.01) and 22.5% (P < 0.05), respectively, in the fifth KHEI quintile compared to the first quintile adjusting for multiple covariates. On the other hand, the linear trend of metabolic syndrome risk across the KHEI levels did not reach the significance level.CONCLUSIONS: A better diet quality can prevent future metabolic syndrome and its certain risk factors among Korean men and women.

ABSTRACT

BACKGROUND AND OBJECTIVES: Recently, Genoss drug-eluting stent (DES)™ stent comprising cobalt-chromium platform with an ultrathin strut thickness, sirolimus, and an abluminal biodegradable polymer was developed. Owing to the lack of substantial evidence for the safety and efficacy of this stent, we report 12-month results of the Genoss DES™ stent.METHODS: We analyzed subjects who were eligible for a 12-month follow-up from the ongoing Genoss DES™ registry, which is a prospective, single-arm, observational, multicenter trial to investigate the clinical outcomes after the successful Genoss DES™ stent implantation among all-comers. The primary endpoint was a device-oriented composite outcome, defined as cardiac death, target vessel-related myocardial infarction, and target lesion revascularization at 12-month follow-up.RESULTS: Among 622 subjects, the mean age of subjects was 66.5±10.4 years, 70.6% were males, 67.5% had hypertension, and 38.3% had diabetes. The implanted stent number, diameter, and length per patient were 1.5±0.8, 3.1±0.4 mm, and 36.0±23.3 mm, respectively. At 12-month clinical follow-up, the primary endpoint occurred only in 4 (0.6%) subjects.CONCLUSIONS: The novel Genoss DES™ stent exhibited excellent safety and efficacy in real-world practice.

ABSTRACT

BACKGROUND AND OBJECTIVES: The objective of this study was to evaluate the long-term clinical outcomes and the incidence of permanent pacemaker implantation after catheter ablation in patients with of atrial fibrillation (AF) and sinus node dysfunction (SND).METHODS: Among 3,068 total consecutive patients who underwent AF catheter ablation (AFCA), this study included 222 (9.5%; men 53.2%, 63.7±9.2 years of age, 81.5% paroxysmal AF) with underlying SND and a regular rhythm follow-up. We analyzed the rhythm outcomes, changes in the mean heart rate or heart rate variability, and permanent pacemaker implantation rate.RESULTS: During 47.5±28.8 months of follow-up, 25 (11.3%) patients received pacemaker implantations due to symptomatic SND. More than half (56.0%, 14/25) underwent a pacemaker implantation within 3 months of the AFCA, and the annual pacemaker implantation rate was 2.0% afterwards. Both the early (68.0% vs. 31.0%, p<0.001) and clinical AF recurrence (68.0% vs. 32.5%, p=0.001) rates and continuous antiarrhythmic drug use after 3 months (44.0% vs. 24.4%, p=0.036) were significantly higher in patients requiring pacemaker implantations than those that did not. An anterior linear ablation (odds ratio [OR], 9.37 [3.03–28.9]; p<0.001) and the E/Em (OR, 1.15 [1.02–1.28]; p=0.018) were independently associated with permanent pacemaker implantations after AFCA in patients with AF and SND.CONCLUSIONS: After AFCA in patients with AF and SND, 1 of 9 patients needed a pacemaker implantation and half needed implantations within 3 months. The AF recurrence rate was significantly higher in those who required pacemaker implantations after the AFCA.

ABSTRACT

PURPOSE: To evaluate clinical outcomes of idiopathic epiretinal membrane removal in patients ≥ 80 years of age.METHODS: A retrospective review of medical records was performed with 56 patients who underwent vitrectomy and removal of idiopathic epiretinal membrane. In the ≥ 80 years of age group (n = 28), the best-corrected visual acuity (BCVA) and central macular thickness (CMT) before surgery were compared with those at the final follow-up. The amount of change in the BCVA after surgery was also compared between the ≥ 80 years of age group and the < 80 years of age group (n = 28).RESULTS: In the ≥ 80 years of age group, the mean follow-up period was 19.1 ± 17.0 months. Before surgery, 11 eyes were pseudophakic and 17 eyes were phakic. Combined cataract surgery was performed with epiretinal membrane removal in all 17 phakic eyes. The mean logarithm of the minimal angle of resolution BCVA was 0.75 ± 0.30 before surgery, which improved to 0.50 ± 0.30 at the final follow-up (p < 0.001). The CMT was 458.0 ± 79.7 µm before surgery, which decreased to 367.2 ± 83.4 µm at the final follow-up (p < 0.001). There was no significant difference in the amount of change in the BCVA after the surgery between the ≥ 80 years of age group and the < 80 years of age group (p = 0.547).CONCLUSIONS: In patients with idiopathic epiretinal membrane who were ≥ 80 years of age, the visual acuity was improved or maintained, and was accompanied with anatomical improvement after epiretinal membrane removal with or without cataract surgery. These results suggest the usefulness of epiretinal membrane removal in older patients.

ABSTRACT

PURPOSE: To evaluate the effectiveness of 0.1% topical bromfenac as an adjunctive treatment with intravitreal bevacizumab (IVB) injection for branch retinal vein occlusion (BRVO) patients.METHODS: We retrospectively evaluated 68 eyes of 68 patients with macular edema (ME) secondary to BRVO who were treated with IVB injection and followed up for at least 12 months. Of the 68 eyes, 38 were treated with IVB combined with 0.1% topical bromfenac and 30 were treated with IVB alone. IVB reinjection was performed in cases of recurrence. The primary outcome measurement was the number of IVB injections. Changes in the best-corrected visual acuity (BCVA) and central foveal thickness (CFT) during the 12-month follow-up were compared.RESULTS: There was no significant difference in the BCVA or CFT between the two groups at the initial and final examinations. However, the number of IVB injections was significantly lower in the 0.1% bromfenac-treated eyes (p < 0.01) than in the control eyes (4.1 ± 0.7 vs. 5.0 ± 0.6 times).CONCLUSIONS: Compared to IVB monotherapy, topical bromfenac as an adjunctive treatment with IVB injection of eyes with ME secondary to BRVO did not affect visual outcomes, but it reduced the number of IVB injections.

ABSTRACT

PURPOSE: We investigated the long-term outcomes of vitrectomy with internal limiting membrane (ILM) peeling as treatment for myopic traction maculopathy (MTM).METHODS: The medical records of patients who underwent vitrectomy to treat MTM were retrospectively evaluated. We excluded patients who exhibited macular holes (MHs) or retinal detachment at the time of primary surgery. The best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were analyzed preoperatively, at 3, 6, 12, and 24 months after surgery, and at the final visit. Complications including retinal detachment or an MH were noted during follow-up.RESULTS: Twenty-three eyes of 22 patients were enrolled. At the time of primary surgery, the mean patient age was 64.4 ± 11.1 years and the baseline mean logMAR BCVA and CFT, 0.67 ± 0.50 and 431.8 ± 159.5 µm, respectively. The mean follow-up period was 53.7 ± 19.3 months. The mean logMAR BCVAs at 3, 6, 12, and 24 months postoperatively and at the final visit were 0.42 ± 0.39 (p = 0.001), 0.41 ± 0.38 (p = 0.001), 0.39 ± 0.40 (p < 0.001), 0.42 ± 0.43 (p < 0.001), and 0.51 ± 0.47 (p = 0.016), respectively, thus significantly better than the baseline value. The mean CFT at 3, 6, 12, and 24 months postoperatively and at the final visit were 244.6 ± 72.3, 210.5 ± 79.1, 209.6 ± 91.6, 219.8 ± 93.9, and 217.7 ± 81.3 µm, respectively, thus significantly less than baseline (all p < 0.001). MTM resolved in 18 eyes (78.3%) after primary surgery, without any complication, and remained stable to the final visit.CONCLUSIONS: Vitrectomy with ILM peeling afforded favorable long-term efficacy and safety in MTM patients.

ABSTRACT

PURPOSE: To compare the efficacy of intravitreal dexamethasone implants according to previous response to bevacizumab treatment in patients with diabetic macular edema (DME).METHODS: Forty-nine eyes of 49 patients who received intravitreal dexamethasone implants for DME were reviewed retrospectively. Of these patients, 13 were treatment-naïve and 36 had previously received intravitreal injections of bevacizumab. Of the 36 previously treated patients, 24 comprised a refractory group showing no response to previous injections, and 12 comprised a responder group showing a response to previous treatments. The best-corrected visual acuity, central macular thickness (CMT), and retreatment percentages were assessed monthly for 6 months.RESULTS: After the intravitreal dexamethasone implants, visual acuity improved significantly over 6 months in the treatment-naïve group, while in the responder group, a significant improvement in visual acuity was seen at the 2-month follow-up. In the refractory group, there was no significant improvement in visual acuity during the follow-up period. The CMT showed a significant decrease in all three groups, and there was no significant difference in the CMT among the three groups at any time point. Five patients in the treatment-naive group (38.5%), 19 patients in the refractory group (79.2%), and nine patients in the responder group (75.0%) needed retreatment for recurrent macular edema, and there was a significant difference among the three groups in the rate of recurrence (p = 0.034).CONCLUSIONS: In DME patients, intravitreal dexamethasone implants were associated with a significant anatomical improvement irrespective of previous bevacizumab treatment response. However, the treatment-naïve and responder groups showed improvements in visual acuity, whereas the refractory group showed limited improvement.
