REVIEW
Matthew F Bouchonville, Sara Matani, Jason J DuBroff, Robert J DuBroff
The global epidemic of obesity and diabetes underscores the urgency to develop strategies to prevent cardiovascular (CV) disease in this vulnerable population. Clinical guidelines are intended to help the clinician manage these patients, but guidelines are often discordant among professional organizations and not always evidence based. Clinicians must rely upon the best available evidence, and therefore we critically reviewed the evidence behind the American Diabetes Association (ADA) 2016 guidelines on the prevention of CV disease in diabetes...

Importance: Oxidative stress is an established dementia pathway, but it is unknown if the use of antioxidant supplements can prevent dementia. Objective: To determine if antioxidant supplements (vitamin E or selenium) used alone or in combination can prevent dementia in asymptomatic older men. Design, Setting, and Participants: The Prevention of Alzheimer's Disease by Vitamin E and Selenium (PREADViSE) trial began as a double-blind randomized clinical trial in May 2002, which transformed into a cohort study from September 2009 to May 2015...

BACKGROUND: In Mexico, although the majority of births are attended in hospitals, reports have emerged of obstetric violence, use of unsafe practices, and failure to employ evidence-based practices (EBP). Recent attention has refocused global efforts towards provision of quality care that is both patient-centered and evidence-based. Scaling up of local interventions should rely on strong evidence of effectiveness. OBJECTIVE: To perform a secondary analysis to evaluate the impact of a simulation and team-training program (PRONTO) on the performance of EBP in normal births...

Oral squamous cell carcinoma (OSCC) represents the sixth most common cancer, accounting for 2-4% of all malignancies worldwide. The overall survival rate of less than 60% remains generally poor, with prognosis heavily relying on the TNM staging system. Tumor size as well as the presence and extent of lymph node metastases are widely recognized as the most important predictors. However, the underlying mechanisms that lead to an aggressive phenotype are not yet fully understood. Therefore, possible biomarkers are much in need to predict prognosis, to help individualize therapy approaches, and to overcome possible resistance mechanisms...

REVIEW
Andrew T Hattersley, Kashyap A Patel
The precision medicine approach of tailoring treatment to the individual characteristics of each patient or subgroup has been a great success in monogenic diabetes subtypes, MODY and neonatal diabetes. This review examines what has led to the success of a precision medicine approach in monogenic diabetes (precision diabetes) and outlines possible implications for type 2 diabetes. For monogenic diabetes, the molecular genetics can define discrete aetiological subtypes that have profound implications on diabetes treatment and can predict future development of associated clinical features, allowing early preventative or supportive treatment...

Listeria monocytogenes is of great concern in food processing facilities because it persists in biofilms, potentiating biotransfer. Stainless steel is commonly used for food contact surfaces and transport containers. L. monocytogenes biofilm on stainless steel served as a model system for surface sampling to test the performance of a sonicating swab in comparison to a standard cotton swab. Swab performance and consistency were determined using total viable counts. Stainless steel coupons sampled with both swabs were examined with SEM to visualize biofilms and surface structures (i...

BACKGROUND: Approximately 18-20% of all human breast cancers have overexpressed human epidermal growth factor receptor 2 (HER2). Standard clinical practice is to treat only overexpressed HER2 (HER2+) cancers with targeted anti-HER2 therapies. However, recent analyses of clinical trial data have found evidence that HER2-targeted therapies may benefit a sub-group of breast cancer patients with non-overexpressed HER2. This suggests that measurement of other biological factors associated with HER2 cancer, such as HER2 signaling pathway activity, should be considered as an alternative means of identifying patients eligible for HER2 therapies...

BACKGROUND: Neutralizing antibodies develop in natural HIV-1 infection. Their development often takes several years and may rely on chronic virus exposure. At the same time recent studies show that treatment early in infection may provide opportunities for immune preservation. However, it is unknown how intermittent treatment in early infection affects development of the humoral immune response over time. We investigate the effect of cART in early HIV infection on the properties of the memory B cell compartment following 6 months of cART or in the absence of treatment...

We examined the neurobiological basis of temporal resetting, an aspect of temporal order memory, using a version of the delayed-match-to-multiple-sample task. While in an fMRI scanner, participants evaluated whether an item was novel or whether it had appeared before or after a reset event that signified the start of a new block of trials. Participants responded "old" to items that were repeated within the current block and "new" to both novel items and items that had last appeared before the reset event (pseudonew items)...

REVIEW
R Sutton
Cardiac pacing for vasovagal syncope (VVS) addresses the cardioinhibitory component of the reflex but cannot directly affect vasodepression, which occurs in every reflex even when hidden by dominant cardioinhibition. The randomized controlled trials of pacing in VVS have, after almost 2 decades, determined that a small number of patients can benefit because their vasodepressor component is not severe. Early studies compared pacing with no therapy yielding highly significant benefits. Subsequently, all study patients had implanted devices with half being switched off...

Wendi Waits, Megan Marumoto, Jennifer Weaver
PURPOSE OF REVIEW: To describe and summarize published research on accelerated resolution therapy (ART), a promising and relatively new psychotherapy with the potential to offer rapid and effective resolution of a wide range of psychiatric symptoms. Unlike most evidence-based psychotherapies, ART is a predominately imaginative therapy that relies upon the rescripting of distressing events and metaphors as one of its key therapeutic elements. RECENT FINDINGS: The number of studies conducted on ART is limited, primarily consisting of one randomized, controlled trial (RCT) with 57 subjects and two large cohort studies involving 80 and 117 subjects, respectively...

The therapeutic landscape of gastroenteropancreatic-neuroendocrine tumors (GEP-NETs) has evolved significantly in recent years. Current and emerging treatment options include somatostatin analogs, radiolabeled somatostatin analogs, the mTOR inhibitor everolimus, and the tyrosine kinase inhibitor sunitinib. Although high-quality data from phase III trials are lacking, cytotoxic agents are commonly used for the treatment of poorly differentiated neuroendocrine carcinomas and well-differentiated NETs originating in the pancreas...

Development of the acquired ALK G1202R solvent front mutation and small cell lung cancer (SCLC) transformation have both been independently reported as resistance mechanisms to ALK inhibitors in ALK-rearranged (ALK+) non-small cell lung cancer (NSCLC) patients but have not been reported in the same patient. Here we report an ALK+ NSCLC patient who had disease progression after ceritinib and then alectinib where an ALK G1202R mutation was detected on circulating tumor (ct) DNA prior to enrollment onto a trial of another next generation ALK inhibitor, lorlatinib...

The potential association of microcephaly and other congenital abnormalities with Zika virus (ZIKV) infection during pregnancy underlines the critical need for a rapid and accurate diagnosis. Due to the short duration of ZIKV viremia in infected patients, a serologic assay that detects antibody responses to viral infection plays an essential role in diagnosing patient specimens. The current serologic diagnosis of ZIKV infection relies heavily on the labor-intensive Plaque Reduction Neutralization Test (PRNT) that requires more than one-week turnaround time and represents a major bottleneck for patient diagnosis...

Despite the enormous research efforts that have been put into the development of central nervous system (CNS) drugs, the success rate in this area is still disappointing. To increase the successful rate in the clinical trials, first the problem of predicting human CNS drug distribution should be solved. As it is the unbound drug that equilibrates over membranes and is able to interact with targets, especially knowledge on unbound extracellular drug concentration-time profiles in different CNS compartments is important...

Ocular gene therapy approaches have been developed for a variety of different diseases. In particular, clinical gene therapy trials for RPE65 mutations, X-linked retinoschisis, and choroideremia have been conducted at different centers in recent years, showing that adeno-associated virus (AAV)-mediated gene therapy is safe, but limitations exist as to the therapeutic benefit and long-term duration of the treatment. The technique of vector delivery to retinal cells relies on subretinal injection of the vector solution, causing a transient retinal detachment...

PURPOSE: Research on sensitive and private topics relies heavily on self-reported responses. Social desirability bias may reduce the accuracy and reliability of self-reported responses. Anonymous surveys appear to improve the likelihood of honest responses. A challenge with prospective research is maintaining anonymity while linking individual surveys over time. METHODS: We have tested a secret code method in which participants create their own code based on eight questions that are not expected to change...

In recently published clinical trial results, hypoxia-modified therapies have shown to provide more positive outcomes to cancer patients, compared with standard cancer treatments. The development and validation of these hypoxia-modified therapies depend on an effective way of measuring tumour hypoxia, but a standardised measurement is currently unavailable in clinical practice. Different types of manual measurements have been proposed in clinical research, but in this paper we focus on a recently published approach that quantifies the number and proportion of hypoxic regions using high resolution (immuno- ) fluorescence (IF) and hematoxylin and eosin (HE) stained images of a histological specimen of a tumour...
