Since the introduction of the sutureless Perceval® (Sorin Group, Saluggia, Italy) in Europe after CE mark in 2012, the "sutureless approach" is becoming more and more popular. Sutureless implantation in general is easy, fast and safe, but bears several potential pitfalls. This might result in inferior functional results affecting also clinical outcomes. In our center, more than 300 implant procedures have been performed up to date by mainly two senior surgeons. The technique is in the process of spreading to all surgeons performing aortic valve procedures...

Darwin described evolution as "descent with modification." Descent, however, is not an explicit focus of most evolution instruction and often leaves deeply held misconceptions to dominate student understanding of common ancestry and species relatedness. Evolutionary trees are ways of visually depicting descent by illustrating the relationships between species and groups of species. The ability to properly interpret and use evolutionary trees has become known as "tree thinking." We used a 20-question assessment to measure misconceptions in tree thinking and compare the proportion of students who hold these misconceptions in an introductory biology course with students in two higher-level courses including a senior level biology course...

The comorbidity of major depressive disorder (MDD) and generalized anxiety disorder (GAD) is common and often predicts poorer outcomes than either disorder alone. This study aimed to examine the prevalence of comorbid GAD and its association with quality of life (QOL) among MDD patients. A total of 1225 psychiatric outpatients were screened using the Hospital Anxiety and Depression Scale (HADS). Those who scored ≥8 on the HADS were interviewed using DSM-IV criteria by two senior psychiatrists. Patients diagnosed with MDD were further assessed using the 9-item Patient Health Questionnaire, Social Support Rating Scale, Pittsburgh Sleep Quality Index, and World Health Organization QOL Scale, brief version (WHOQOL-BREF)...

INTRODUCTION: Surgery is an extreme physiological stress for the elderly. Aging is inevitably associated with irreversible and progressive cellular degeneration. Patients above 75 years of age are characterized by impaired responses to operative stress and a very narrow safety margin. AIM: To evaluate perioperative complications in patients aged ≥ 75 years who underwent cardiac surgery in comparison to outcomes in younger patients. MATERIAL AND METHODS: The study was conducted at the Silesian Centre for Heart Diseases in Zabrze in 2009-2014 after a standard of perioperative care in seniors was implemented to reduce complications, in particular to decrease the duration of mechanical ventilation and reduce postoperative delirium...

BACKGROUND: Bronchiolitis is a common respiratory illness of early childhood. For most children it is a mild self-limiting disease but a small number of children develop respiratory failure. Nasal continuous positive airway pressure (nCPAP) has traditionally been used to provide non-invasive respiratory support in these children, but there is little clinical trial evidence to support its use. More recently, high-flow nasal cannula therapy (HFNC) has emerged as a novel respiratory support modality...

This cluster-randomized trial was designed to determine the efficacy of a 6-month exercise-nutritional supplement program (ENP) on physical function and nutritional status for older adults and the feasibility of implementing this program in a senior living setting. Twenty senior living facilities were randomized to either a three day per week group-based ENP led by a trained facility staff member or a health education program (SAP). Participants (N=121) completed a short physical performance battery, 400 meter walk, handgrip strength test, and mini-nutrition assessment...

Studies have reported that intraplaque neovascularisation (IPN) is closely correlated with plaque vulnerability. In this study, a new image processing approach, differential intensity projection (DIP), was developed to visualise and quantify IPN in contrast-enhanced non-linear ultrasound image sequences of carotid arteries. DIP used the difference between the local temporal maximum and the local temporal average signals to identify bubbles against tissue non-linear artefact and noise. The total absolute and relative areas occupied by bubbles within each plaque were calculated to quantify IPN...

OBJECTIVE: This study examined the use of triptan derivatives in Australia between 1997 and 2015, based on a national drug reimbursement database, and compared patterns of use with available international data. METHODS: We obtained publically available data on the number of prescriptions for triptans marketed in Australia (sumatriptan, eletriptan, rizatriptan, zolmitriptan, naratriptan). Dispensed use was measured as defined daily dose (DDD per 1000 population per day) for Australia's concessional beneficiaries (low-income earners, people with disabilities, and seniors)...

OBJECTIVE: Single-camera-based gait monitoring is unobtrusive, inexpensive and easy-to-use to monitor daily gait of seniors in their homes. However, most studies require subjects to walk perpendicularly to camera's optical axis or along some specified routes, which limits its application in elderly home monitoring. To build unconstrained monitoring environments, we propose a method to measure step length symmetry ratio (a useful gait parameter representing gait symmetry without significant relationship with age) from unconstrained straight walking using a single camera, without strict restrictions on walking directions or routes...

The senior population in Hawai'i is growing at a dramatic pace. In the older population, falls and fall-related injuries are leading causes of morbidity and mortality. Moreover, the health care costs for falls are very high. The State of Hawai'i has taken measures to prevent falls through the promotion of medication reviews, vision checks, home assessments, and exercise. However, current published examinations of fall preventive measures have been insufficient, and more research is needed to confirm risk factors, effectiveness of preventive measures, and to explore future objectives...

BACKGROUND: Appropriate balancing of the patellofemoral joint (PFJ) using a lateral release can help to prevent patellar instability in total knee arthroplasty (TKA). Contemporary total knee implant designs are characterized by enhanced trochlear geometry more similar to native knee anatomy to minimize instability and reduce utilization of a lateral release. METHODS: We retrospectively reviewed consecutive TKA cases from a single senior surgeon's practice with 3 successive total knee designs: the Press-Fit Condylar (PFC), the Sigma, and the ATTUNE (DePuy, Warsaw, IN)...

The sigmoid sinus is routinely exposed and manipulated during pre-sigmoid, transpetrosal approaches to the skull base, but there is scant data available on the incidence of venous sinus compromise after surgery. We encountered a dural arteriovenous fistula as a result of sigmoid sinus occlusion and examined the incidence of venous sinus thrombosis or narrowing after transpetrosal surgeries. We performed a retrospective analysis of a series of patients treated by the senior surgeons (WCJ, MH, HJK), who underwent either a posterior petrosectomy or translabyrinthine approach for various skull base tumors...
