A single-centre experience of His bundle pacing without electrophysiological mapping system: implant success rate, safety, pacing characteristics and one-year follow up

INTRODUCTION@#Despite the challenges related to His bundle pacing (HBP), recent data suggest an improved success rate with experience. As a non-university, non-electrophysiology specialised centre in Singapore, we report our experiences in HBP using pacing system analyser alone.@*METHODS@#Data of 28 consecutive patients who underwent HBP from August 2018 to February 2019 was retrospectively obtained. The clinical and technical outcomes of these patients were compared between two timeframes of three months each. Patients were followed up for 12 months.@*RESULTS@#Immediate technical success was achieved in 21 (75.0%) patients (mean age 73.3 ± 10.7 years, 47.6% female). The mean left ventricular ejection fraction was 53.9% ± 12.1%. The indications for HBP were atrioventricular block (n = 13, 61.9%), sinus node dysfunction (n = 7, 33.3%) and upgrade from implantable cardioverter-defibrillator to His-cardiac resynchronisation therapy (n = 1, 4.8%). No significant difference was observed in baseline characteristics between Timeframe 1 and Timeframe 2. Improvements pertaining to mean fluoroscopy time were achieved between the two timeframes. There was one HBP-related complication of lead displacement during Timeframe 1. All patients with successful HBP achieved non-selective His bundle (NSHB) capture, whereas only eight patients had selective His bundle (SHB) capture. NSHB and SHB capture thresholds remained stable at the 12-month follow-up.@*CONCLUSION@#Permanent HBP is feasible and safe, even without the use of an electrophysiology recording system. This was successfully achieved in 75% of patients, with no adverse clinical outcomes during the follow-up period.

Ablación exitosa con radiofrecuencia a través de la cúspide coronariana derecha de un complejo ventricular prematuro parahisiano / Successful radiofrequency ablation through the right coronary cups of a parahisian premature ventricular complexes

Resumen Los complejos ventriculares prematuros (CVP) son hallazgos frecuentes en individuos con o sin enfermedad estructural cardiaca. Los CVP cuyo origen se localiza en la región parahisiana son poco frecuentes y su manejo a través de ablación con catéter de radiofrecuencia es un reto, pues su localización favorece un alto riesgo de desarrollo de bloqueo aurículo-ventricular. Se describen dos casos de pacientes con CVP parahisianos llevados a ablación con catéter de radiofrecuencia.

Abstract Premature ventricular complexes (PVC) are common findings in patients with or without structural heart disease. Parahisian PVC are uncommon and their management through radiofrequency catheter ablation remains a challenge, since their location favors a high risk for developing atrioventricular block. Two cases of patients with parahisian PVC undergoing radiofrequency catheter ablation are described.

Objective:To investigate the role of HIS (hyperinflammatory syndrome) score in predicting the prognosis of anti-melanoma differentiation associated gene 5(MDA5) antibody-positive dermatomyositis (DM) patients with interstitial lung disease (ILD).Methods:A total of 43 patients with anti-MDA5 antibody-positive dermatomyositis and 228 connective tissue disease (CTD) patients with ILD hospitalized in the First Affiliated Hospital of Nanjing Medical University from January 2018 to April 2021 were enrolled into this study. All patients were complicated with ILD and their HIS score were assessed. Non-parametric Mann-Whitney U test, Chi-squared test, Fisher exact probability and receiver operating characteristic (ROC) curve were used for data analysis. Results:The HIS score of 43 patients with anti-MDA5 antibody-positive dermat-omyositis were collected. Among 228 CTD-ILD patients in the control groups, the primary disease consisted of 33(14.5%) anti-synthetase antibody syndrome (ASS), 44(19.3%) rheumatoid arthritis (RA), 65(28.5%) Sj?gren's syndromes (SS), 43 (18.9%) systemic sclerosis (SSc) and 43 (18.9%) systemic lupus erythematosus(SLE). The HIS score of anti-MDA5-positive DM-ILD patients [2(1, 3)] was higher than those in ASS patients [1(0, 2), Z=-2.06, P<0.05] and significantly higher than those in RA-ILD [1(0, 2), Z=-2.87, P<0.01], SS-ILD [0(0,1), Z=-5.78, P<0.01], SSC-ILD [1(0, 1), Z=-3.84, P<0.01] and SLE-ILD [1(0, 2), Z=-3.81, P<0.01]. Comparing HIS score of anti-MDA5-positive DM-ILD patients, the 3-months mortality rate in the low, medium and high groups was 0(0/15), 38.1%(8/21) and 85.7%(6/7). The area under ROC curve (95% CI) was 0.857[(0.747, 0.967), P<0.001] for HIS score in predicting 3-months mortality probability of anti-MDA5-positive DM-ILD. Conclusion:HIS score of anti-MDA5-positive DM-ILD is higher than that in CTD-ILD patients and the baseline level is related to the 3-months mortality rate.

MIL-53-based homochiral metal-organic framework as a stationary phase for open-tubular capillary electrochromatography / 药物分析学报

Homochiral metal-organic frameworks(MOFs)have attracted considerable attention in many fields of research,such as chiral catalysis and chiral chromatography.However,only few homochiral MOFs can be effectively used in capillary electrochromatography(CEC)and their performances are far from adequate.In this study,we successfully synthesized achiral nanocrystalline MIL-53.A facile post-synthetic modi-fication strategy was then implemented to functionalize the product,yielding a homochiral MOF:L-His-NH-MIL-53.This MOF was then employed as a chiral coating in open-tubular CEC mode(OT-CEC),and,as such,it exhibited high enantioselectivities for several racemic drugs.The homochiral MOF and the fabricated capillary coating were systematically characterized using transmission electron microscopy,scanning electron microscopy(with energy-dispersive X-ray spectrometry),Fourier-transform infrared spectroscopy,X-ray diffractometry,thermogravimetric analysis,circular dichroism spectroscopy,Bru-nauer-Emmett-Teller surface area measurements,and X-ray photoelectron spectroscopy.This study is expected to provide a new strategy for the design and establishment of MOF-based chiral OT-CEC systems.

Manejo de la insuficiencia cardiaca con estimulación hisiana en bloqueo de rama derecha: reporte de caso / Management of heart failure with His bundle pacing in right bundle branch block: case report

Resumen La terapia de resincronización cardiaca mediante estimulación hisiana ha demostrado ser efectiva en pacientes con bloqueo de rama izquierda del haz de His e insuficiencia cardiaca. Paciente masculino, con 47 años de edad, con insuficiencia cardiaca, fracción de expulsión del 17% y miocardio dilatada idiopática, electrocardiograma en ritmo sinusal, bloqueo auriculoventricular de 1.er grado, intervalo PR 400 ms, bloqueo completo de rama derecha del haz de His, bloqueo del fascículo anterior de la rama izquierda del haz de His, duración del QRS 200 ms. Se decidió realizar estimulación selectiva del haz de His. La resincronización cardiaca biventricular convencional en pacientes con presencia de bloqueo completo de la rama derecha del haz de His no está indicada debido a la pobre respuesta al tratamiento. La estimulación hisiana permite reclutar la rama bloqueada y reestablecer la conducción a través de ella, de tal forma que, en ausencia de necrosis, se logre sincronía biventricular. En el caso presentado el reclutamiento de la rama derecha mediante estimulación hisiana se reflejó en el restablecimiento de la sincronía biventricular, medida por rastreo de marcas (speckle tracking) e incremento significativo de la fracción de expulsión del ventrículo izquierdo del 17 al 36.6%, con un incremento absoluto del 19.6%.

Abstract Cardiac resynchronization therapy has proven to be an effective therapy in patients with left bundle branch block and heart failure. Male, 47 years old, heart failure with a left ventricle ejection fraction of 17%, idiopathic heart failure. ECG with sinus rhythm, 1st degree AV block, PR 400 ms, complete right bundle branch block, anterior hemi-fascicle of the left bundle of His, and QRS duration 200 ms. We decided to perform a selective His bundle pacing. In patients with right bundle branch block the biventricular cardiac resynchronization is not indicated due to low treatment response. His bundle pacing allows recruiting the blocked branch and restoring conduction throughout it, therefore, in the absence of necrosis the biventricular synchrony is achieved. We presented a case of His bundle pacing with recruitment of the right bundle branch, which reestablish biventricular synchrony measured by speckle tracking, and with a significant increase of the left ventricle ejection fraction from 17 to 36.6%, with an absolute increase of 19.6%.

Ablação por Cateter de Taquicardia Atrial Focal com Ativação Precoce Próxima ao Feixe de His, a Partir da Cúspide Aórtica não Coronária / Catheter Ablation of Focal Atrial Tachycardia with Early Activation Close to the His-Bundle from the Non Coronary Aortic Cusp

Resumo Fundamento A ablação da taquicardia atrial (TA) com local de ativação mais precoce próxima ao feixe de His é um desafio, devido ao risco de bloqueio de AV completo por sua proximidade ao sistema de His-Purkinje (SHP). Uma alternativa para minimizar esse risco é posicionar o cateter na cúspide não coronária (CNC), que é anatomicamente contígua à região para-Hissiana. Objetivos O objetivo deste estudo foi fazer uma revisão de literatura e avaliar as características eletrofisiológicas, a segurança e o índice de sucesso de aplicação de radiofrequência (RF) por cateter na CNC para o tratamento de TA para-Hissiana em uma série de casos. Métodos Avaliamos retrospectivamente dez pacientes (Idade: 36±10 anos) que foram encaminhados para ablação de taquicardia paroxística supraventricular (TPSV) e haviam sido diagnosticados com TA focal para-Hissiana confirmada por manobras eletrofisiológicas clássicas. Para a análise estatística, um P valor d <0.05 foi considerado estatisticamente significativo. Resultados A ativação atrial mais precoce na posição His foi de 28±12ms da onda P, e a CNC foi 3±2ms antes da posição His, sem evidência de potencial His em todos os pacientes. Foi aplicada RF à CNC (cateter de ponta de 4-mm; 30W, 55°C) e a taquicardia foi interrompida em 5±3s sem aumento no intervalo PR ou evidência de um ritmo juncional. Os testes eletrofisiológicos não induziram novamente a taquicardia em 9/10 pacientes. Não houve complicações em nenhum procedimento. Durante o período de acompanhamento de 30 ± 12 meses, nenhum paciente apresentou recorrência de taquicardia. Conclusão O tratamento percutâneo de TA para-Hissiana por meio de CNC é uma estratégia segura e eficiente, tornando-se uma opção interessante para o tratamento de arritmia complexa. (Arq Bras Cardiol. 2021; 116(1):119-126)

Abstract Background Atrial tachycardia (AT) ablation with earliest activation site close to the His-Bundle is a challenge due to the risk of complete AV block by its proximity to His-Purkinje system (HPS). An alternative to minimize this risk is to position the catheter on the non-coronary cusp (NCC), which is anatomically contiguous to the para-Hisian region. Objectives The aim of this study was to perform a literature review and evaluate the electrophysiological characteristics, safety, and success rate of catheter-based radiofrequency (RF) delivery in the NCC for the treatment of para-Hisian AT in a case series. Methods This study performed a retrospective evaluation of ten patients (Age: 36±10 y-o) who had been referred for SVT ablation and presented a diagnosis of para-Hisian focal AT confirmed by classical electrophysiological maneuvers. For statistical analysis, a p-value of <0.05 was considered statistically significant. Results The earliest atrial activation at the His position was 28±12ms from the P wave and at the NCC was 3±2ms earlier than His position, without evidence of His potential in all patients. RF was applied on the NCC (4-mm-tip catheter; 30W, 55ºC), and the tachycardia was interrupted in 5±3s with no increase in the PR interval or evidence of junctional rhythm. Electrophysiological tests did not reinduce tachycardia in 9/10 of patients. There were no complications in all procedures. During the 30 ± 12 months follow-up, no patient presented tachycardia recurrence. Conclusion The percutaneous treatment of para-Hisian AT through the NCC is an effective and safe strategy, which represents an interesting option for the treatment of this complex arrhythmia.

Challenges and opportunities in improving left ventricular remodelling and clinical outcome following surgical and trans-catheter aortic valve replacement / 医学前沿

Over the last half century, surgical aortic valve replacement (SAVR) has evolved to offer a durable and efficient valve haemodynamically, with low procedural complications that allows favourable remodelling of left ventricular (LV) structure and function. The latter has become more challenging among elderly patients, particularly following trans-catheter aortic valve implantation (TAVI). Precise understanding of myocardial adaptation to pressure and volume overloading and its responses to valve surgery requires comprehensive assessments from aortic valve energy loss, valvular-vascular impedance to myocardial activation, force-velocity relationship, and myocardial strain. LV hypertrophy and myocardial fibrosis remains as the structural and morphological focus in this endeavour. Early intervention in asymptomatic aortic stenosis or regurgitation along with individualised management of hypertension and atrial fibrillation is likely to improve patient outcome. Physiological pacing via the His-Purkinje system for conduction abnormalities, further reduction in para-valvular aortic regurgitation along with therapy of angiotensin receptor blockade will improve patient outcome by facilitating hypertrophy regression, LV coordinate contraction, and global vascular function. TAVI leaflet thromboses require anticoagulation while impaired access to coronary ostia risks future TAVI-in-TAVI or coronary interventions. Until comparable long-term durability and the resolution of TAVI related complications become available, SAVR remains the first choice for lower risk younger patients.

Esquema de confianza basado en Infraestructura de clave pública (PKI) para el intercambio de información clínica electrónica en el sistema XAVIA HIS / PKI-based trust scheme for the exchange of electronic clinical information in the XAVIA HIS system

La seguridad informática se ha convertido en una necesidad y un derecho de todos los ciudadanos. Los sistemas informáticos empleados en el sector de salud poseen un almacenamiento digital fácil y sostenible que debe garantizar la privacidad e integridad de la información, lo cual constituye cuestión delicada. En Cuba no está definido un esquema PKI (Públic Key Infraestructure) o Infraestructura de Clave Pública, centralizado a nivel nacional que propicie y garantice la seguridad de la información sensible en el sistema de salud pública, lo cual pone en riesgo la autenticidad, integridad y confidencialidad de los datos médicos personales. Este trabajo tiene como objetivo diseñar una estructura de seguridad centrada en la PKI entre las instituciones de salud, a partir de la infraestructura de llave pública nacional como autoridad de certificación raíz. Se realizó un análisis documental sobre la actualidad del tema, se realizaron entrevistas a administrativos, gestores hospitalarios y especialistas en seguridad informática, lo cual permitió crear las bases de la investigación. Se obtuvo un esquema de confianza que propicia el intercambio seguro de los registros médicos de los pacientes entre instituciones de salud. La implementación de una infraestructura PKI en el sector sanitario permite que las instituciones que requieran intercambiar registros médicos, a través de una red, puedan hacerlo con un alto nivel de seguridad(AU)

Computer security has become a necessity and a right for all citizens. The IT systems used in the health sector have much easier and more sustainable digital storage and guarantee the privacy and integrity of information, which are sensitive issues. In Cuba, there is no centralized PKI (Public Key Infrastructure) scheme at the national level that promotes and guarantees the security of sensitive information in the public health system, which puts the authenticity, integrity and confidentiality of personal medical data at risk. The aim of our work was to design a security structure centered on PKI among health institutions, based on the national public key infrastructure as root certificate authority (CA). In order to achieve this, a documentary analysis was carried out on the current state of the art in the subject; as well as interviews with administrative staff, hospital managers and specialists in computer security, which allowed the research bases to be created. As a result, a trust scheme was obtained that promotes the secure exchange of patients' medical records between health institutions. The implementation of a PKI infrastructure in the health sector allows institutions to exchange medical records through a network with a high level of security(AU)

Optical coherence tomography detection of changes in inner retinal and choroidal thicknesses in patients with early retinitis pigmentosa / Detecção por tomografia de coerência óptica das alterações da retina interna e da espessura de coroide em pacientes com retinite pigmentosa precoce

ABSTRACT Purpose: To evaluate the inner retinal and choroidal thicknesses in patients with early retinitis pigmentosa. Methods: We analyzed spectral-domain optical coherence tomography images of 35 retinitis pigmentosa patients and 40 healthy individuals. We measured macular and ganglion cell complex thicknesses. We took choroidal thickness measurements in the subfoveal region and 500, 1,000, and 1,500 mm from the foveal center. Results: Patients with retinitis pigmentosa had significantly thinner macular thicknesses and choroidal thicknesses in all measurements, and their individual ganglion cell complex thickness measurements were lower than those in healthy individuals. The mean ganglion cell complex thickness was significantly lower in patients with retinitis pigmentosa than that in controls. The mean macular thickness was significantly correlated with the mean choroidal and mean ganglion cell complex thicknesses. (We found no correlation between the mean choroidal thickness and the mean ganglion cell complex thickness). Conclusions: The choroid was mildly affected in our patients with early retinitis pigmentosa. The tendency toward significance in the inner retina was possibly caused by a good visual acuity.

RESUMO Objetivo: Avaliar as espessuras internas da retina e da coroide em pacientes com retinite pigmentosa precoce. Métodos: Foram analisadas imagens de tomografia de coerência óptica de domínio espectral de 35 pacientes com retinite pigmentosa e 40 indivíduos saudáveis. Medimos a espessura do complexo de células maculares e ganglionares. Realizamos medições da espessura da coroide na região subfoveal e a 500 mm, 1000 mm e 1500 mm do centro da fóvea. Resultados: Pacientes com retinite pigmentosa apresentaram espessuras maculares e da coroide significativamente mais finas em todas as medições e suas medidas individuais da espessura do complexo de células ganglionares foram inferiores às de indivíduos saudáveis. A espessura média do complexo de células ganglionares foi significativamente menor nos pacientes com retinite pigmentosa do que nos controles. A espessura macular média foi significativamente correlacionada com as espessuras médias do complexo das células de coroide e das células ganglionares médias. Não encontramos correlação entre a espessura media da coroide e a espessura media do complexo de células ganglionares. Conclusões: A coroide foi levemente afetada em nossos pacientes com retinite pigmentosa precoce. A tendência à significância na retina interna foi possivelmente causada por uma boa acuidade visual.

An Overview of Recent Trend of Crime in the Nature of ‘Cruelty by Husband or his Relatives’ in our Country

Crime against women is a gross violence of their human rights and hampers their overall welfare, but unfortunately crime iscommitted against women throughout the centuries without any social, cultural and national barrier. Women of our countryare also not free from this tradition. They are also the poor victims of several form of crimes throughout the centuries. It is ashameful fact that women are victimised not only outside their home but also in their own home and by their near and dearones. Physical, sexual and psychological violence strikes women in every part of our country. It has crossed the boundary ofevery society, economy, religion, race and culture. The statistics published by ‘National Crime Records Bureau’, an IndianGovernment agency and part of the Ministry of Home Affairs, indicates the share of crime against women under the head‘Cruelty by Husband or his relatives’ u/s 498A IPC is the maximum among all crimes against women in recent past in ourcountry. An attempt has been made through this paper to view the recent trend of this crime in different States and UnionTerritories and actions taken by police administration and judicial system to give justice to the victims of this crime.

Complex network analysis of combination medication of patients with kidney malignant tumor based in real world / 中国中药杂志

Kidney malignant tumor is a type of primary renal cell carcinoma, and mainly refers to renal cancer. The incidence of kidney cancer and the number of hospital cases in China have been increasing. Based on the clinical medicine information of patients in the hospital information system(HIS) database of 37 hospitals in China, the combined medication of patients with kidney malignant tumor were analyzed by Tabu search algorithm, so as to analyze the combined medication of patients with kidney malignant tumor in real world. A total of 7 095 patients with kidney malignant tumor were included, the ratio of males to females was 2.11∶1, and the ratio of male patients increased gradually with age. About 3 933 patients(55.43%) showed a superior effect among those patients. The common therapies of patients with kidney malignant tumor were anti-tumor therapies and symptomatic therapies, including anti-infection, regulation of electrolyte balance, sedation and analgesia, analgesic, regulation of gastrointestinal function.

Permanent HIS bundle Pacing Feasibility in Routine Clinical Practice: Experience from an Indian Center

There is a paucity of experience regarding His bundle pacing (HBP) at laboratories initially attempting the procedure, especially in the Indian scenario. Patient who underwent HBP were selected for pacing therapy or in lieu of cardiac resynchronization therapy (CRT) at a single center. Among 22 patients attempted, 19 patients underwent successful implant, achieving selective HBP in 14 patients. There was a significant improvement in left ventricular ejection fraction (LVEF) (49.3 ± 9.3 vs. 36.7 ± 9.2) in the LV dysfunction subgroup (n = 6). Over a follow-up of 15 ± 6.5 months, thresholds were stable in all except one patient, and there was no requirement of lead revision. In summary, we found that HBP is a feasible option for achieving physiological pacing.
