Challenges in the training of military surgeons: experiences from Dutch combat operations in southern Afghanistan
submitted by 15 minutes ago - Topic: Health
To improve care for battle casualties, we analyzed the surgical workload during the Dutch deployment to Uruzgan, Afghanistan. This surgical workload was compared with the resident surgical training and the pre-deployment medical specialist program. Patient data from the trauma registry (2006–2010) at the Dutch Role 2 Medical Treatment Facility (MTF) were analyzed. The case logs of chief resid...



Autotransfusion in emergent operative trauma resuscitation
submitted by 15 minutes ago - Topic: Health
Autotransfusion of red cells is common in many surgical specialties. However, this technique is not uniformly used in abdominal trauma. The purpose of this paper is to study the outcomes of patients who were autotransfused during emergency trauma operations in which they sustained full-thickness hollow viscus injury (HVI). A total of 179 patients in period 1999–2008 with penetrating and blunt...

Short- and long-term effects of nocturnal oxygen therapy on sleep apnea in chronic heart failure
submitted by 16 minutes ago - Topic: Health
This paper studies the short- and long-term effects of nocturnal oxygen therapy (NOT) on sleep apnea in chronic heart failure (CHF). We enrolled 51 adults in New York Heart Association (NYHA) heart failure functional classes II or III, ≤45 % left ventricular ejection fraction (LVEF), in a randomized, open, single-center study. Nocturnal cardiorespiratory polygraphy showed sleep apnea [apnea-...

Mapping the Evolution of Spatial Exciton Coherence through Time-Resolved Fluorescence
submitted by 16 minutes ago - Topic: Biology
Quantum coherence is expected to have a positive effect on the transfer efficiency of excitation energy through photosynthetic aggregates and conjugated polymers, but its significance to the functioning of these molecular assemblies remains largely unknown. We propose a new experimental means to monitor the coherence between distant molecular sites on a time scale relevant to energy transfer. T...

Anomalous Hysteresis in Perovskite Solar Cells
submitted by 16 minutes ago - Topic: Biology
Perovskite solar cells have rapidly risen to the forefront of emerging photovoltaic technologies, exhibiting rapidly rising efficiencies. This is likely to continue to rise, but in the development of these solar cells there are unusual characteristics that have arisen, specifically an anomalous hysteresis in the current–voltage curves. We identify this phenomenon and show some examples of fac...



Interaction of NH3 with Cu-SSZ-13 Catalyst: A Complementary FTIR, XANES, and XES Study
submitted by 17 minutes ago - Topic: Biology
In the typical NH3–SCR temperature range (100–500 °C), ammonia is one of the main adsorbed species on acidic sites of Cu-SSZ-13 catalyst. Therefore, the study of adsorbed ammonia at high temperature is a key step for the understanding of its role in the NH3–SCR catalytic cycle. We employed different spectroscopic techniques to investigate the nature of the different complexes occurring u...

Visible-Range Sensitization of Er3+-Based Infrared Emission from Perfluorinated 2-Acylphenoxide Complexes
submitted by 17 minutes ago - Topic: Biology
Five new fully fluorinated acylphenoxide ligands, which are aromatic analogues of β-diketonates, provide visible photosensitization of the Er3+4I13/2 → 4I15/2 emission at 1540 nm (of interest for telecommunications) via the “antenna effect”, as observed in Cs[ErL4] compounds. Depending on the chemical functionalization, the excitation wavelength can be tuned in the 400–650 nm range. De...


Administration of 100% oxygen does not hasten resolution of symptomatic spontaneous pneumothorax in neonates
submitted by 18 minutes ago - Topic: Health
To compare the effectiveness of 100% oxygen therapy vs oxygen treatment with targeted pulse oximetry in the management of symptomatic small to moderate spontaneous pneumothorax (SP). In total, 100% oxygen treatment for SP has been a common practice in neonatology, albeit there is little evidence to validate its efficacy. Study A retrospective chart review of 83 neonatal records ...

The diagnostic impact of limited, screening obstetric ultrasound when performed by midwives in rural Uganda
submitted by 20 minutes ago - Topic: Health
To evaluate the diagnostic impact of limited obstetric ultrasound (US) in identifying high-risk pregnancies when used as a screening tool by midwives in rural Uganda. Study This was an institutional review board-approved prospective study of expecting mothers in rural Uganda who underwent clinical and US exams as part of their standard antenatal care visit in a local health center in the Isingi...


The utility of pain scores obtained during ‘regular reassessment process’ in premature infants in the NICU
submitted by 21 minutes ago - Topic: Health
To examine the association of pain assessment scores achieved through regular reassessment practice, as required by the Joint Commission (JC), with painful events and the use of analgesics in premature, ventilated infants. Study A cross-sectional study was performed in two tertiary level neonatal intensive care units. Pain was assessed at regular intervals at each center using validated multidi...

Neurodevelopmental outcomes after hypothermia therapy in the era of Bayley-III
submitted by 21 minutes ago - Topic: Health
Bayley-III scales are currently used to evaluate outcomes of term infants following hypothermia therapy, while all before reported outcomes in this population have used Bayley-II. Our objectives were to determine the incidence of abnormal neurodevelopmental outcomes using Bayley III and the predictive value of Magnetic resonance imaging (MRI) in infants who received systemic hypothermia. Study ...


Effects of maternal iodine supplementation during pregnancy and lactation on iodine status and neonatal thyroid-stimulating hormone
submitted by 21 minutes ago - Topic: Health
To determine the iodine status in pregnant and lactating women, as well as neonatal thyroid-stimulating hormone (TSH) concentration. Study Pregnant women cared at our hospital, the University Hospital in Bangkok, had routinely received 200 μg iodine tablet daily since October 2010. Urinary iodine concentrations (UICs) of 1508 pregnant and 87 lactating women and 76 offspring and b...

Tapentadol potentiates descending pain inhibition in chronic pain patients with diabetic polyneuropathy
submitted by 21 minutes ago - Topic: Health
Tapentadol is an analgesic agent for treatment of acute and chronic pain that activates the µ-opioid receptor combined with inhibition of neuronal norepinephrine reuptake. Both mechanisms are implicated in activation of descending inhibitory pain pathways. In this study, we investigated the influence of tapentadol on conditioned pain modulation (CPM, an experimental measure of endogenous ...

Systematic review and meta-analysis of the effect of intraoperative alpha2-adrenergic agonists on postoperative behaviour in children
submitted by 21 minutes ago - Topic: Health
Undergoing general anaesthesia is distressing for children, with up to two-thirds demonstrating abnormal behaviours after their procedure, such as emergence delirium (ED) and post-hospitalization behaviour change. The aim of this systematic review was to determine the effect of intraoperative i.v. α2-adrenergic agonists on postoperative behaviour in children. We included published full-te...

EuroSCORE II and N-terminal pro-B-type natriuretic peptide for risk evaluation: an observational longitudinal study in patients undergoing coronary artery bypass graft surgery
submitted by 21 minutes ago - Topic: Health
Postoperative heart failure remains the major cause of death after cardiac surgery. As N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a predictor for postoperative heart failure, the aim was to evaluate if preoperative NT-proBNP could provide additional prognostic information to the recently launched EuroSCORE II. A total of 365 patients with acute coronary syndrome (ACS) undergoing i...
