Zaheer Nabi, Duvvur Nageshwar Reddy
Gastrointestinal (GI) endoscopy plays an indispensable role in the diagnosis and management of various pediatric GI disorders. While the pace of development of pediatric GI endoscopy has increased over the years, it remains sluggish compared to the advancements in GI endoscopic interventions available in adults. The predominant reasons that explain this observation include lack of formal training courses in advanced pediatric GI interventions, economic constraints in establishing a pediatric endoscopy unit, and unavailability of pediatric-specific devices and accessories...

Animal models are valuable tools for screening novel therapies for patients who suffer from epilepsy. However, a wide array of models are necessary to cover the diversity of human epilepsies. In humans, neonatal hypoxia (or hypoxia-ischemia) is one of the most common causes of epilepsy early in life. Hypoxia-induced seizures (HS) during the neonatal period can also lead to spontaneous seizures in adulthood. This phenomenon, i.e., early-life hypoxia leading to adult epilepsy - is also seen in experimental models, including rats...

BACKGROUND: This paper concerns public health crises today-the problem of opioid prescription access and related abuse. Inspired by Case and Deaton's seminal work on increasing mortality among white Americans with lower education, this paper explores the relationship between opioid prescribing and local economic factors. OBJECTIVE: We examined the association between county-level socioeconomic factors (median household income, unemployment rate, Gini index) and opioid prescribing...

PURPOSE OF REVIEW: Since the recent black-box warning regarding the use of electromechanical morcellation, there has been a hesitancy to utilize the product and even to perform other types of morcellation by gynecologists. Unfortunately, this Food and Drug Administration action and the continued public criticisms of this procedure are grounded in poor data and faulty reasoning. To truly perform informed consent to patients considering procedures involving morcellation, a thorough review of the facts, not alternative facts, must be communicated...

Reye syndrome is a rare but a very dangerous emergency that children and teenagers suffer. This threatening condition occurs during the treatment of fever in the clinical course of viral diseases with drugs containing acetylsalicylic acid and other salicylates. The high mortality rate from this disease is associated with the development of a rapidly progressing toxic encephalopathy and hepatic insufficiency. The etiology and pathogenesis of the Reye syndrome, despite the large number of investigations, is not clear enough...

We introduce a method for directly imaging depletion layers in operando with elemental specificity and chemical speciation at sub-100 nm spatial resolution applicable to today's three-dimensional electronic architectures. These typically contain complex, multicomponent designs consisting of epitaxial heterostructures, buried domains, or nanostructures with different shapes and sizes. Although the variety of devices is immense, they commonly rely on carrier separation in a built-in potential induced by composition or strain gradients...

Conjunctival reconstruction is an integral component of ocular surface restoration. Decellularised tissues are frequently used clinically for tissue engineering. This study identifies porcine decellularised conjunctiva (PDC) and human decellularised conjunctiva (HDC) as promising substitutes for conjunctival reconstruction. PDC and HDC were nearly DNA-free, structurally intact and showed no cytotoxic effects in vitro, which was confirmed by DNA quantification, histology, transmission electron microscopy, collagen quantification and cytotoxicity assay...

REVIEW
David E Cummings, Francesco Rubino
Several bariatric operations originally designed to promote weight loss have been found to powerfully treat type 2 diabetes, causing remission in most cases, through diverse mechanisms additional to the secondary consequences of weight loss. These observations have prompted consideration of such operations as 'metabolic surgery', used expressly to treat diabetes, including among patients who are only mildly obese or merely overweight. Large, long-term observational studies consistently demonstrate that bariatric/metabolic surgery is associated with reductions in all cardiovascular risk factors, actual cardiovascular events, microvascular diabetes complications, cancer and death...

Alejandra T Rabadán, Vilma A Tripodoro
In healthcare, an ethical concern that arises during the decision making process is considered to be a bioethical dilemma. It is often the case that in the absence of proper deliberation, the problem is transferred to a bioethics committee, not even representing precisely a dilemma. Bioethics emerged as a discipline in the mid-20th century. It is defined as a support to decision-making in ethical dilemmas centered on two aspects: ethics of clinical investigation, focused on protecting the rights of research subjects, and bioethics in medical practice, of an advisory nature...

The ion channel arrest hypothesis has been the foundation of three decades of research into the underlying mechanisms of hypoxia/anoxia tolerance in several key species, including: painted turtles, goldfish, crucian carp, naked mole rats, and arctic and ground squirrels. The hypothesis originally stated that hypoxia/anoxia tolerant species ought to have fewer ion channels per area membrane and/or mechanisms to regulate the permeability of ions through channels. Today we can add to this and include mechanisms to remove channels from membranes and the expression of low conductance isoforms...

BACKGROUND: Retinopathy of prematurity (ROP) is a proliferative vitreoretinopathy resulting from vascular defect of the retina. The present study evaluates platelets, which are involved in VEGF storage, transport and release, and their functions with regard to the prognosis of the disease. The objective was to suggest a simple minimal invasive method that will facilitate the management of the disease and help clinicians in predicting the prognosis. METHODS: In this single center, retrospective, case-control study, we included a control group consisting of very preterm newborns (n = 83) at risk of ROP and a laser photocoagulation group including infants (n = 63) who received laser therapy during their follow-up examinations...

MicroRNAs are small noncoding single-stranded RNAs that regulate gene expression. Today, we see an increasing number of studies highlighting the important role of microRNAs in the development and progression of cardiovascular diseases caused by atherosclerotic lesions of arteries. We review the available scientific data on association of the expression of these biomolecules with instability of atherosclerotic plaques in animal models and humans. We made special emphasis on miR-21, -100, -127, -133, -143/145, -221/222, and -494 because they were analyzed in more than one study...

Stroke represents the most common fatal neurological disease especially in highly developed countries. Even today, treatment options are very limited. The development of new therapeutic approaches replies, to a great extent, on experimental rodent models of focal cerebral ischemia. Since ~80% of ischemic strokes occur in the area of middle cerebral artery (MCA), a number of these stroke models are based on this artery. The intraluminal monofilament model of MCA occlusion involves the insertion of a surgical filament inside the external carotid artery and its extension into the internal carotid artery until the tip occludes the source of the MCA-thus arresting blood flow with resultant infarction in the MCA area...

The human nose takes primary responsibility for preconditioning inhaled air. Numerous pathologies can affect the physiology of the nose. The beginnings of flow analyzes were carried out with three-dimensional casting models and differently colored liquids. Temperature and humidity could not be taken into account. Today, much more complex analyzes are possible using computational fluid dynamics (CFD), which are based on three-dimensional models generated from computed tomography (CT) or magnetic resonance imaging (MRI) datasets...

Chronic myeloid leukemia (CML) is the best example of successful targeted therapy. Today, the overall survival of patients with CML treated by using tyrosine kinase inhibitors (TKIs) is very close to that of the healthy population. The current question is: how can we further ameliorate the clinical outcome of patients with CML? Clinical trials have shown that some patients with CML in the chronic phase who achieve sustained deep molecular responses on TKI therapy can safely suspend therapy with no evidence of relapse...

BACKGROUND: Inflammatory bowel disease (IBD) is a chronic gastrointestinal condition affecting over 5 million people globally and 1.6 million in the United States but currently lacks a precisely determined cause or cure. The range of symptoms IBD patients experience are often debilitating, and the societal stigmas associated with some such symptoms can further degrade their quality of life. Better understanding the nature of this public reproach then is a critical component for improving awareness campaigns and, ultimately, the experiences of IBD patients...

Since the improvement of cancer diagnosis and treatment, survival rates of these patients increase. Gonadal damages are frequent consequences of cancer treatments with different evidence of impaired fertility. In this context, fertility preservation should be proposed to patients exposed to potentially gonadotoxic treatments. Different preservation approaches may be proposed depending on patient age, sex, cancer type and type of treatment. The indications of fertility preservation depend on sexual maturity...

Volunteering to serve the general interest, that is the profession of faith behind associative commitments. Notably, actions by associations undertaken in favour of organ donation today must, in their content and forms, reconcile tradition and modernity. But they keep their driving principles and values intact.

Healthcare commitment is a mosaic of attention to and encounters with the Other, with brotherhood and effectiveness. It means knowing the rules, but not submitting to norms. It is a responsibility that comes from the feeling of one's own vulnerability as much as it is a question of sharing the values of the sick person with other healthcare personnel.
