Optical coherence tomography (OCT) delivers 3-dimensional images of tissue microstructures. Although OCT imaging offers a promising high-resolution method, OCT images experience some artifacts that lead to misapprehension of tissue structures. Speckle, intensity decay, and blurring are 3 major artifacts in OCT images. Speckle is due to the low coherent light source used in the configuration of OCT. Intensity decay is a deterioration of light with respect to depth, and blurring is the consequence of deficiencies of optical components...

BACKGROUND: Food insecurity (FI) remains a major public health problem. With the rise in suburban poverty, a greater understanding of parents' experiences of FI in suburban settings is needed to effectively screen and address FI in suburban practices. METHODS: We conducted 23 semistructured interviews with parents of children <4 years of age who presented for well-child care in 6 suburban pediatric practices and screened positive for FI. In the interviews, we elicited parents' perceptions of screening for FI, how FI impacted the family, and recommendations for how practices could more effectively address FI...

BACKGROUND: National organizations recommend pediatricians screen for food insecurity (FI). Although there has been growing research in urban practices, little research has addressed FI screening in suburban practices. We evaluated the feasibility, acceptability, and impact of screening in suburban practices. METHODS: We conducted a mixed methods study that implemented FI screening in 6 suburban pediatric primary care practices. We included all children presenting for either a 2-, 15-, or 36-month well-child visit (N = 5645)...

PURPOSE: Hemodynamics in cerebral aneurysms is currently investigated towards its clinical efficacy using non-standardized computational simulation techniques. At the same time, flow patterns and velocities are accessible by 4D phase contrast magnetic resonance imaging (4D pcMRI). Complexity of protocol design and imaging duration has limited the use of this technique in clinical imaging. A new approach is presented to overcome these limitations. MATERIAL AND METHODS: 3D replicas of two cerebral aneurysms were fabricated by fused deposition prototyping (3D printing) and imaged using 4D pcMRI while connected to an MRI compatible continuous flow loop...

PTEN is the second most frequently mutated tumor suppresser gene in cancers after p53. Genetic and epigenetic alterations in the PTEN gene and its regulatory regions have been reported in various studies. PTEN is a crucial downregulator of the pro-survival phosphoinositide 3-kinase/Akt/mammalian target of rapamycin pathway and also suppresses insulin signaling. Failure to regulate these pathways leads to increase in cell proliferation and migration which in turn promotes tumorigenesis. PTEN underexpression is mediated by a variety of cytokines and stress kinases which seem to collectively induce the RAS/mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) pathway...

We present cardiac computed tomography (CT) findings demonstrating apical hypertrophic cardiomyopathy with dystrophic calcification of the left ventricular apex. The absence of significant epicardial coronary artery disease demonstrated by coronary CT angiography suggests that increased wall tension and decreased microvascular perfusion over time account for the dyskinetic apical myocardium, rather than myocardial infarction secondary to atherosclerotic plaque rupture. These observations support CT as the imaging modality of choice to visualize the deposition of calcium in injured myocardial tissue, a recognized occurrence in chronically infarcted myocardium...

Squamous cell carcinoma of the head and neck (SCCHN) is a difficult to treat malignancy and represents the seventh most common cancer worldwide. Systemic therapy has a critical role in the treatment of locally advanced and recurrent/metastatic disease. Cytotoxic chemotherapy has been primarily used along with radiation and surgery, with cisplatin being the standard of care choice of therapy. When contraindications to cisplatin exist, other agents such as carboplatin, taxanes, 5-fluorouracil, and cetuximab are used...

Posttraumatic hemorrhagic contusions are a common sequel of traumatic brain injuries. They occur in around 8% of all traumatic brain injuries. Spontaneous resolution of acute subdural and acute extradural hematomas, although rare, is a recognized entity, but spontaneous resolution of the hemorrhagic component of a contusion within 24 h has not been reported in the literature. We present a patient in whom the hemorrhagic component of her contusion resolved spontaneously over a period of 24 h after injury. The rarity of this case prompted us to this study...

The human brain is plastic, i.e. it can show structural changes in response to the altered environment. Physical activity (PA) is a lifestyle factor which has significant associations with the structural and functional aspects of the human brain, as well as with the mind and body health. Many studies have reported regional/global brain volume increments due to exercising; however, a map which shows the overall extent of the influences of PAs on brain structure is not available. In this study, we collected all the reports on brain structural alterations in association with PA in healthy humans, and next, a brain map of the extent of these effects is provided...

Heterozygous gain-of-function (GOF) mutations in the signal transducer and activator of transcription 1 (STAT1) have increasingly been identified as a genetic cause of autosomal-dominant (AD) chronic mucocutaneous candidiasis (CMC). In this article, we describe a 33-year-old man who experienced chronic refractory candidiasis, recurrent otitis media, and pneumonia resulting in bronchiectasis, severe oral and esophageal candidiases with strictures associated with hypothyroidism and immune hemolytic anemia. His son also suffered from persistent candidiasis, chronic diarrhea, poor weight gain, and pneumonia that resulted in his demise because of sepsis...

Seminal studies using post-mortem brains of patients with Alzheimer's disease evidenced aberrant insulin-like growth factor 1 receptor (IGF1R) signalling. Addressing causality, work in animal models recently demonstrated that long-term suppression of IGF1R signalling alleviates Alzheimer's disease progression and promotes neuroprotection. However, the underlying mechanisms remain largely elusive. Here, we showed that genetically ablating IGF1R in neurons of the ageing brain efficiently protects from neuroinflammation, anxiety and memory impairments induced by intracerebroventricular injection of amyloid-β oligomers...
