Cellular adhesion and chondrogenic differentiation inside an alginate-based bioink in response to tailorable artificial matrices and tannic acid treatment.

Many established bioinks fulfill important requirements regarding fabrication standards and cytocompatibility. Current research focuses on development of functionalized bioinks with an improved support of tissue-specific cell differentiation. Many approaches primarily depend on decellularized extracellular matrices or blood components.

Extended septal myectomy using a combined trans-aortic and apical approach for long basal and mid-cavity hypertrophic cardiomyopathy.

Unlabelled: Surgical septal myectomy is the treatment of choice for patients of hypertrophic cardiomyopathy who are symptomatic despite maximal medical therapy. Residual obstruction results in the persistence of symptoms and poorer outcomes. The length (depth) of the septum excised as far towards the apex is important.

Novel behavioral model in evaluating initiation and sustenance of teeth brushing behavior among students pursuing health sciences: a cross-sectional study.

Oral hygiene maintenance is a crucial and integral feature in determining the overall wellbeing of a person. It has been established that interventions for health promotion at the public health level derived from theoretical models based on social and behavioural sciences have a superior effectiveness as compared to the ones without a theoretical background. Hence a novel behavioral model known as the multi-theory model (MTM) was used to understand two important aspects of health behavior change: (i) Initiation and (ii) Sustenance in twice daily teeth brushing in a university setting with objectives to identify factors effecting MTM in initiation and sustenance of twice daily brushing behavior among students pursuing health sciences and correlating the MTM theory with socio-demographic and behavioral patterns.

Hardware Failure as a Rare Complication of Percutaneous Coronary Intervention: A Case Report.

Percutaneous coronary intervention (PCI) is increasingly employed in the treatment of complex coronary artery disease. The entrapment or fracture of a coronary angioplasty guidewire is a rare complication of PCI. We herein describe a 61-year-old man who presented with chronic stable angina.

Infections of the aorta.

Infection of the aorta continues to be a clinical challenge with high morbidity and mortality. The incidence varies between 0.6 and 2.

Complex complete transposition of great arteries and partial anomalous pulmonary venous connection with an intact interatrial septum-lessons learnt.

The association of pulmonary venous anomaly and a complex complete transposition of great arteries (d-TGA) is a rarity. Managing a combination of anomalies in a single setting is a surgical challenge. We report a very rare association of d-TGA with ventricular septal defect (VSD) and partial anomalous pulmonary venous connection (PAPVC) of the right pulmonary veins to the right atrium with an intact interatrial septum in a month-old infant.

An unusual cause of acute mitral regurgitation in TTK Chitra heart valve prosthesis.

Structural failure of mechanical heart valve was a known feature when it was evolving in the 1960s and 1970s. With the advent of pyrolytic carbon and a better design, it is a rare entity with present valves. We report a case of disc fracture leading to acute mitral regurgitation in TTK Chitra heart valve prosthesis (CHVP) (TTK Healthcare Limited, India) heart valve, 6 years after its implantation in mitral position.

Intra-operative trans-esophageal echocardiography in heart valve disease.

Peri-operative echocardiography is widely used because it provides information that significantly influences clinical/surgical management and improves outcome in patients undergoing cardiac surgery. The role of intra-operative trans-esophageal echocardiography (TEE) in valvular heart disease cannot be emphasized enough. Increasing use of newer surgical techniques-valve repairs and minimal invasive cardiac surgery also warrants intra-operative TEE.

Incidence, prevalence, and mortality associated with head and neck cancer in India: Protocol for a systematic review.

Background: Head and neck cancer (HNC) is a heterogeneous tumor at various anatomic sites and one of the most common cancers in India. Published and existing reports and studies highlight an alarming increase in the incidence, prevalence, and mortality of HNC. Despite its high incidence, there is a dearth of more precise estimates of reliable epidemiological data pertaining to HNC in India.

Chasing the umbrella: delayed migration of ductal occluder device into the aorta.

Delayed migration of a ductal occluder device into the aorta after transcatheter closure of a patent ductus arteriosus is extremely rare. We present a case of delayed migration of a ductal occluder into the descending aorta 4 months after its deployment in an 11-year-old girl. Successful surgical removal of the device from the descending aorta and triple-ligation of the ductus arteriosus was performed via a left thoracotomy.

Head and neck cancer risk factors in India: protocol for systematic review and meta-analysis.

Introduction: Demographic, behavioural and environmental factors have been associated with increased risk of head and neck cancer (HNC). We will review published reports and explore connections between risk factors and HNC incidence. This protocol aims to provide strategies for a systematic review and meta-analysis of HNC risk factor analysis in India.
