The Effects of Endobronchial Coil Therapy on Right Ventricular Functions.

Lung hyperinflation is an important therapeutic target in symptomatic emphysema patients. Endobronchial therapies that reduce end-expiratory lung volume are increasingly being used in advanced cases. However, there is paucity of data regarding the effects of these therapies on the heart functions. The aim of this study is to evaluate the right ventricular functions before and after the procedure in patients who underwent endobronchial coil therapy (EBCT).Patients who were between 18 and 80 years of age and scheduled for EBCT with GOLD 3-4 were enrolled in the study. Right heart functions were evaluated using MPI, TAS, TAPSE. Right atrium area and maximum velocity of tricuspid regurgitation were also noted.A total of 23 patients were enrolled in the study. 21 patients underwent bilateral intervention, while only 2 patients received unilateral treatment. There was an improvement in MPI (0.49 ± 0.15 vs 0.39 ± 0.11, p < 0.001) and TAS (11.6 (9 - 15) vs 13.2 (9.80 - 17.0), p = 0.001). Peak TRV (2.52 ± 0.6, 2.38 ± 0.6, p = 0.02) and PASP values were lower in the post-operative period (41.15 ± 5.94 vs 36.83 ± 8.01 p = 0.019).In this current study, we found improved echocardiographic RtV parameters in patients who received EBCT treatment.

The Utility of Genetic Testing in Infantile Epileptic Spasms Syndrome: A Step-Based Approach in the Next-Generation Sequencing Era.

BACKGROUND: To evaluate the utility of genetic testing for etiology-specific diagnosis (ESD) in infantile epileptic spasms syndrome (IESS) with a step-based diagnostic approach in the next-generation sequencing (NGS) era. METHODS: The study cohort consisted of 314 patients with IESS, followed by the Pediatric Neurology Division of Ege University Hospital between 2005 and 2021. The ESD was evaluated using a step-based approach: step I (clinical phenomenology), step II (neuroimaging), step III (metabolic screening), and step IV (genetic testing). The diagnostic utility of genetic testing was evaluated to compare the early-NGS period (2005 to 2013, n = 183) and the NGS era (2014 to 2021, n = 131). RESULTS: An ESD was established in 221 of 314 (70.4%) infants with IESS: structural, 40.8%; genetic, 17.2%; metabolic, 8.3%; immune-infectious, 4.1%. The diagnostic yield of genetic testing increased from 8.9% to 41.7% in the cohort during the four follow-up periods. The rate of unknown etiology decreased from 34.9% to 22.1% during the follow-up periods. The genetic ESD was established as 27.4% with genetic testing in the NGS era. The genetic testing in the NGS era increased dramatically in subgroups with unknown and structural etiologies. The diagnostic yields of the epilepsy panels increased from 7.6% to 19.2%. However, the diagnostic yield of whole exome sequencing remained at similar levels during the early-NGS period at 54.5% and in the NGS era at 59%. CONCLUSIONS: The more genetic ESD (27.4%) was defined for IESS in the NGS era with the implication of precision therapy (37.7%).

Assessment of Prognostic Factors and Validity of Scoring Models in Childhood Autoimmune Encephalitis.

OBJECTIVE: The aim of this study is to evaluate the prognostic factors in a single-center pediatric cohort with autoimmune encephalitis. MATERIALS AND METHODS: The study group consisted of 23 pediatric autoimmune encephalitis patients (seropositive autoimmune encephalitis: 15, seronegative autoimmune encephalitis: 8). Five group prognostic parameters were evaluated: clinical manifestations, elect roenc ephal ograp hy features, magnetic resonance imaging characteristics, biomarkers, and treatment modalities. Three scoring models were applied: the Antibody Prevalence in Epilepsy and Response to Immunotherapy in Epilepsy for predicting autoimmune-related epilepsy in the whole cohort and the anti-N-methyl-d-aspartate receptor Encephalitis 1-Year Functional Status score for overall outcome in patients with anti-N-methyl-d-aspartate receptor encephalitis. RESULTS: The initial clinical spectrum of the disease was similar in the seronegative and seropositive groups. Almost half of the patients (48%) recovered without any complications with first-line immunotherapy. The patients with movement disorders in the acute phase of the disease needed more likely second-line immunotherapy (P = .039). The presence of status epilepticus at admission was significantly associated with adverse outcomes and the development of autoimmune-related epilepsy (P = .019). Autoimmune-related epilepsy was defined in an equal proportion of patients (91.5%) with 2 immune epilepsy scores (Antibody Prevalence in Epilepsy and Response to Immunotherapy in Epilepsy). The N-methyl-d-aspartate receptor Encephalitis 1-Year Functional Status score and the modified Rankin score assessed for the first-year prognosis were strongly correlated among the patients with anti-N-methyl-d-aspartate receptor encephalitis (P = .03, Spearmen's rho = 0.751). CONCLUSIONS: The presence of status epilepticus was the most important prognostic factor in the patients with the adverse outcome. The studied scoring models (Anti-N-methyl-d-aspartate receptor Encephalitis 1-Year Functional Status, Antibody Prevalence in Epilepsy, and Response to Immunotherapy in Epilepsy) have also been proven to be applicable to the pediatric age group for predicting overall outcome and autoimmune-related epilepsy.

Relationship between Systemic Immune-Inflammation Index and Coronary Collateral Circulation in Patients with Chronic Total Occlusion. / Relação entre o Índice Imune-inflamação Sistêmico e Circulação Colateral Coronariana em Pacientes com Oclusão Total Crônica.

BACKGROUND: Inflammation plays a key role in the initiation and progression of coronary artery disease (CAD). The systemic immune-inflammation index (SII) is a novel inflammatory parameter that has been shown to be associated with CAD. OBJECTIVE: This study aimed to investigate the relationship between SII and coronary collateral circulation (CCC) in patients with stable CAD and chronic total occlusion (CTO). METHODS: The patients were divided into two groups, with poor CCC and good CCC, according to the Rentrop Classification. Ninety-four patients had poor CCC, and 81 patients had good CCC. Inflammation parameters were calculated from the laboratory results. The statistical significance level applied was 0.05. RESULTS: High SII level (OR: 1.003, 95% CI: 1.001-1.004, p<0,001), absence of CTO in RCA (OR: 0.204, 95% CI: 0.096-0.436, p<0,001) and low Gensini score (OR: 0.980, 95% CI: 0.962-0.998, p=0,028) were significantly associated with poor CCC. The cutoff value of SII was 679.96 for the highest predictive power of poor CCC, with a sensitivity of 74.5% and specificity of 43.2%. Mortality rates were similar between the two groups during a mean follow-up of 21.5±10.8 months (p=0.107). CONCLUSIONS: High SII level, the absence of CTO in the right coronary artery, and low Gensini score were significantly related to poor CCC. The rapid and cost-effective use of new inflammatory markers in clinical practice guides the prognosis of CAD.

FUNDAMENTO: A inflamação desempenha um papel fundamental no início e na progressão da doença arterial coronariana (DAC). O Índice Imune-inflamação Sistêmico (SII) é um novo parâmetro inflamatório que demonstrou estar associado à DAC. OBJETIVOS: Este estudo teve como objetivo investigar a relação entre o SII e a circulação colateral coronariana (CCC) em pacientes com DAC estável e oclusão crônica total (OTC). MÉTODOS: Os pacientes foram divididos em dois grupos, com CCC deficiente e CCC boa, de acordo com a Classificação Rentrop. Noventa e quatro pacientes apresentavam CCC deficiente e 81 pacientes CCC boa. Os parâmetros de inflamação foram calculados a partir dos resultados laboratoriais. O nível de significância estatística aplicado foi de 0,05. RESULTADOS: Alto nível de SII (OR: 1,003, IC 95%: 1,001-1,004, p<0,001), ausência de OTC na ACD (artéria coronária direita) (OR: 0,204, IC 95%: 0,096-0,436, p<0,001) e baixo escore de Gensini (OR: 0,980, IC 95%: 0,962-0,998, p=0,028) foram significantemente associados com CCC deficiente. O valor de corte do SII foi de 679,96 para o maior poder preditivo de CCC deficiente, com sensibilidade de 74,5% e especificidade de 43,2%. As taxas de mortalidade foram semelhantes entre os dois grupos durante um seguimento médio de 21,5±10,8 meses (p=0,107). CONCLUSÕES: Alto nível de SII, ausência de OTC na artéria coronária direita e baixo escore de Gensini foram significantemente relacionados à CCC deficiente. O uso rápido e custo-efetivo de novos marcadores inflamatórios na prática clínica orienta o prognóstico da DAC.
