Heartburn is the most specific symptom of gastroesophageal reflux disease (GERD). In clinical practice, heartburn relief by a proton pump inhibitor (PPI) trial does suffice to confirm GERD. However, an objective diagnosis of GERD is required before anti-reflux endoscopic or surgical interventions, independently from PPI response. Thus, since normal findings at upper endoscopy are detected in the majority of patients with heartburn, reflux monitoring is often required. When traditional catheter-based or wireless pH tests are used, reflux episodes are conventionally identified by pH drops below 4...

BACKGROUND: Patients having coronary artery disease treated by coronary bypass or PCI procedure are exposed to tissue damage because of the phenomenon called reperfusion injury. Reperfusion injury can be characterized/monitored by oxidative stress parameters, inflammatory markers and by post-operative complication rate. OBJECTIVE: Beyond the obvious factors determining its severity (affected myocardial mass, ischaemic time, collateral circulation etc.) we examined the GST enzyme group's most cardio selective member, GSTP1 and its genetic polymorphism if there is any genetically determined preventive effect on the above-mentioned parameters...

BACKGROUND: Interest in medical malpractice and areas of medico-legal vulnerability for practicing obstetricians and gynecologists has grown substantially, and many providers report changing surgical practice out of fear of litigation. Furthermore, education on medical malpractice and risk management is lacking for obstetrics and gynecology trainees. Recent obstetric and gynecologic malpractice claims data is lacking. We report on recent trends in malpractice claims for obstetrics and gynecology procedures, and compare these trends to those of other medical specialties...

Nursing and healthcare-associated pneumonia (NHCAP) is a category of healthcare-associated pneumonia that was modified for the healthcare system of Japan. The NHCAP guidelines stated the difficulty in assessing the severity classifications, for instance, A-DROP. We compared the usefulness of different severity classifications (A-DROP, CURB-65, PSI, and I-ROAD) in predicting the prognosis of nursing and healthcare-associated pneumonia. We conducted a retrospective analysis on 303 adult patients hospitalized for nursing healthcare-associated pneumonia and community-acquired pneumonia, which were diagnosed at the Department of Respiratory Medicine of Niigata General City Hospital between January 2012 and December 2014...

BACKGROUND: The transition from medical student to hospital-based first year junior doctor (termed "intern" in Australia) is known to be challenging, and recent changes in clinical learning environments may reduce graduate preparedness for the intern workplace. Although manageable challenges and transitions are a stimulus to learning, levels of burnout in junior medical colleagues are concerning. In order to prepare and support medical graduates, educators need to understand contemporary junior doctor perspectives on this transition...

REVIEW
M Ashraf, A A R Souka
The recent VIEW studies have demonstrated the non-inferiority of monthly and bi-monthly aflibercept in the management of wet age related macular degeneration (AMD) compared with ranibizumab. However, the current data are limited mainly to fixed dosing regimens with few studies looking at flexible dosing regimens of aflibercept in wet AMD. In addition, recent data from the VIEW 96 week extension has shown that patients being shifted from fixed dosing regimens to PRN have shown a drop in visual acuity and increase in central macular thickness...

PURPOSE: Can a mixture of hydroxyapatite (HA) and autologous bone from decompression sites produce similar results when used for transforaminal lumbar interbody fusion (TLIF)? In the current literature, autologous iliac crest bone grafts (ICBGs) have been reported the gold standard for this procedure. Indeed, to date, no clinical data have confirmed that a mixture of equal volumes of HA and local autologous bone produce similar results in term of fusion as the same volume of autologous ICBG alone...

Computational fluid dynamics (CFD) is a mathematical tool to analyse airflow. As currently CFD is not a usual tool for rhinologists, a group of engineers in collaboration with experts in Rhinology have developed a very intuitive CFD software. The program MECOMLAND(®) only required snapshots from the patient's cross-sectional (tomographic) images, being the output those results originated by CFD, such as airflow distributions, velocity profiles, pressure, temperature, or wall shear stress. This is useful complementary information to cover diagnosis, prognosis, or follow-up of nasal pathologies based on quantitative magnitudes linked to airflow...

BACKGROUND: In eosinophilic esophagitis (EoE) the esophageal barrier integrity is impaired. Integrity can be assessed with different techniques. AIMS: To assess the correlations between esophageal eosinophilia and various measures of mucosal integrity, and to evaluate whether endoscopic impedance measurements can predict disease activity. METHODS: Endoscopies and mucosal integrity measurements were performed in adult EoE patients with active disease (≥15 eosinophils/HPF) at baseline (n=32), after fluticasone (n=15) and elemental dietary treatment (n=14) and in controls (n=19)...

Alterations to the pulmonary surfactant system have been observed consistently in ventilation-induced lung injury including composition changes and impairments in the surface tension reducing ability of the isolated extracellular surfactant. However, there is limited information about the effects of VILI on the intracellular form of surfactant, the lamellar body. It is hypothesized that VILI leads to alterations of lamellar bodies numbers and function. To test this hypothesis, rats were randomized to one of three groups, non-ventilated controls, control ventilation and high tidal volume ventilation (VILI)...

The working gas turbine blades are exposed to the environment of high temperature, especially in the leading-edge region. The mist/air two-phase impingement cooling has been adopted to enhance the heat transfer on blade surfaces and investigate the leading-edge cooling effectiveness. An Euler-Lagrange particle tracking method is used to simulate the two-phase impingement cooling on the blade leading-edge. The mesh dependency test has been carried out and the numerical method is validated based on the available experimental data of mist/air cooling with jet impingement on a concave surface...

The structural and photoluminescence (PL) properties of thin films of poly(3-hexylthophene) (P3HT) with molecular weights (MWs) of 3000 and 13,300 have been investigated. Although high MW P3HT always self-organizes into one packing structure (form I), low MW P3HT forms two different packing structures (forms I and II) depending on the fabrication conditions. In this work, several fabrication techniques have been examined to obtain form II samples with little inclusion of a form I component. It is found that drop-cast thin films of low MW P3HT (form II) exhibit a PL spectrum that is different from that of form I and does not contain the form I component...

In the current study the dynamics of glucocorticoid uptake by zebrafish chorionated embryos from the surrounding medium were studied, using 2.5 μM cortisol or dexamethasone solutions complemented with their tritiated variant. We measured the uptake of radioactive cortisol by embryos during a 1 h submersion. Interestingly, the signal in chorionated embryos was 85% (exposure: 1-2 hpf) or 78% (exposure: 48-49 hpf) of the signal present in an equal volume medium. By comparing embryos measured without chorion, we found that 18-20% of the radioactivity present in chorionated embryos is actually bound to the chorion or located in the perivitelline space...
