BACKGROUND: Liver resection is the curative treatment for patients with colorectal liver metastases (CRLMs), with five-year survival rates of 30-50%. Radiofrequency ablation (RFA) is a local and useful alternative for patients with non-resectable CRLMs to obtain complete tumor clearance. The aim of this study was to analyze survival rates with this local treatment. MATERIALS AND METHODS: All patients who underwent RFA and resection or RFA alone for unresectable CRLMs between 2001 and 2012 were included in a retrospective study...

OBJECTIVE: Perinatal depression is a common and costly health concern with serious implications for the mother and child. We sought to quantify the "Perinatal Depression Treatment Cascade"-the cumulative shortfalls in clinical recognition, initiation of treatment, adequacy of treatment, and treatment response for women with antenatal (AND) and postpartum depression (PPD). DATA SOURCES: A systematic search was conducted to identify articles about diagnostic rates, treatment rates, adequate treatment rates, and remission rates for AND and PPD...

The incidence of anterior cruciate ligament (ACL) injuries is rising every year. The autologous hamstring tendon graft, using semitendinosus tendon (SMT) and gracilis tendon (GR), is a common repair technique in the management of ACL injuries due to its multiple advantages. Using a final graft with a minimum diameter of 8 mm is necessary to avoid graft failure. The aim of this study was to find a correlation between preoperative ultrasound (USG) measurement of the SMT and GR tendon diameters (SMTd and GRd) and their actual diameters measured during the grafting procedure...

We developed two new FRET imaging measures for intramolecular FRET biosensors, called linearly proportional (LP) and highly contrasting (HC) measures, which can be easily calculated by the fluorescence intensities of donor and acceptor as a ratio between their weighted sums. As an alternative to the conventional ratiometric measure, which non-linearly depends on the fraction of active molecule, we first developed the LP measure, which is linearly proportional to the fraction of active molecules. The LP measure inherently unmixes bleed-through signals and is robust against fluorescence noise...

BACKGROUND: Electrogram-based identification of the regions maintaining persistent Atrial Fibrillation (AF) is a subject of ongoing debate. Here, we explore the concept of local electrical dyssynchrony to identify AF drivers. METHODS AND RESULTS: Local electrical dyssynchrony was calculated using mean phase coherence. High-density epicardial mapping along with mathematical model were used to explore the link between local dyssynchrony and properties of wave conduction...

The balsam woolly adelgid (Adelges piceae (Ratzeburg) (Homoptera: Adelgidae)) (BWA) is a nonnative, invasive insect that threatens Abies species throughout North America. It is well established in the Pacific Northwest, but continues to move eastward through Idaho and into Montana and potentially threatens subalpine fir to the south in the central and southern Rocky Mountains. We developed a climatic risk model and map that predicts BWA impacts to subalpine fir using a two-step process. Using 30-year monthly climate normals from sites with quantitatively derived BWA damage severity index values, we built a regression model that significantly explained insect damage...

BACKGROUND: Low lean body mass (LBM) is an indicator of malnutrition inflammation syndrome, which is common in hemodialysis (HD) patients. The creatinine index (CI) has been validated as a reliable method to estimate LBM and evaluate the protein-energy status of HD patients. However, the traditional creatinine index formula was complex. We sought to investigate the impact of CI derived from a new simple formula on Chinese HD patient outcomes. METHODS: In this retrospective cohort study, we enrolled 1269 patients who initiated HD between February 1981 and February 2012 and followed them until the end of February 2013...

BACKGROUND: The existing estimate of the global burden of latent TB infection (LTBI) as "one-third" of the world population is nearly 20 y old. Given the importance of controlling LTBI as part of the End TB Strategy for eliminating TB by 2050, changes in demography and scientific understanding, and progress in TB control, it is important to re-assess the global burden of LTBI. METHODS AND FINDINGS: We constructed trends in annual risk in infection (ARI) for countries between 1934 and 2014 using a combination of direct estimates of ARI from LTBI surveys (131 surveys from 1950 to 2011) and indirect estimates of ARI calculated from World Health Organisation (WHO) estimates of smear positive TB prevalence from 1990 to 2014...

In cases of Dengue fever, late hospital admission can lead to treatment delay and even death. In order to improve early disease notification and management, it is essential to investigate the factors affecting the time of admission of Dengue cases. This study determined the factors associated with the time of admission among notified Dengue cases. The study covered the period between 2008 and 2014 in Region VIII, Philippines. The factors assessed were age, sex, hospital sector, hospital level, disease severity based on the 1997 WHO Dengue classification, and period of admission (distinguishing between the 2010 Dengue epidemic and non-epidemic time)...

INTRODUCTION: This study is designed to investigate whether the pharmacokinetics of the antituberculous agent isoniazid (INH) varied according to the circadian dosing-time. METHODS: A total of 168 male mice aged 10 weeks and synchronized for 3 weeks to 12h light and 12h dark were used. A single INH (100mg/kg) dose was administered by intraperitonal (i.p.) route at either of the four different circadian stages (1, 7, 13 and 19h after light onset, HALO). At each circadian stage, blood samples were withdrawn at 0, 0...

Several methods exist to compute the likelihood ratio LR(M, g) evaluating the possible contribution of a person of interest with genotype g to a mixed trace M. In this paper we generalize this LR to a likelihood ratio LR(M1, M2) involving two possibly mixed traces M1 and M2, where the question is whether there is a donor in common to both traces. In case one of the traces is in fact a single genotype, then this likelihood ratio reduces to the usual LR(M, g). We explain how our method conceptually is a logical consequence of the fact that LR calculations of the form LR(M, g) can be equivalently regarded as a probabilistic deconvolution of the mixture...

Meta-analysis, the statistical combination of results from multiple studies, can be used to summarize all of the available research on an intervention, etiology, descriptive, or diagnostic test accuracy question. Meta-analysis should be conducted as a component of a systematic review, to increase transparency in the selection of studies and to incorporate an evaluation of the risk of bias in the individual studies included in the meta-analysis. The process of meta-analysis may include a forest plot to graphically display the study results and the calculation of a weighted average summary effect size...

Appendectomy is standard of care for uncomplicated appendicitis, but cancer patients may not be optimal surgical candidates. Interval appendectomy is controversial, and appendiceal malignancy is rare. Study objectives were to review the role of surgery, observation, and interventional radiology (IR)-guided drainage in patients with appendicitis and advanced malignancy. Retrospective review was performed on cancer patients presenting to a tertiary academic cancer center from January 1, 2001 to December 31, 2014...

Blood transfusions cause altered immunity and the duration of storage is contributory. In the era of massive transfusion protocols (MTPs) this impact is unclear, particularly as it relates to balanced transfusions. Trauma patients requiring our MTP after admission to our Level II trauma center were studied. The average age of blood transfused was calculated; old blood was a storage time of ≥14 days versus new blood <14 days. Blood to plasma ratios of 1:1 were compared with ratios >1:1. Infections, organ dysfunction multiorgan injury (MOI), and death were compared based on ratios and blood storage times...

The electroless deposition of Pt nanoparticles (NPs) on hydrogen-terminated silicon (H-Si) surfaces is studied as a function of temperature and the immersion time. It is demonstrated that isolated Pt structures can be produced at all investigated temperatures (between 22 and 75°C) for short deposition times, typically within 1-10 min if the temperature was 45°C or less than 5 min at 75°C. For longer times, dendritic metal structures start to grow leading ultimately to highly rough interconnected Pt networks...

Mesocrystals composed of crystallographically-aligned nanocrystals are present in biominerals and assembled materials which show strongly directional properties of importance for mechanical protection and functional devices. Mesocrystals are commonly formed by complex biomineralisation processes and can also be generated by assembly of anisotropic nanocrystals. Here, we follow the evaporation-induced assembly of maghemite nanocubes into mesocrystals in real-time in levitating drops. Analysis of time-resolved small angle X-ray scattering data and ex-situ scanning electron microscopy together with interparticle potential calculations show that the substrate-free, particle-mediated crystallization process proceeds in two stages involving the formation and rapid transformation of a dense, structurally disordered phase into ordered mesocrystals...

Glucose nanoconfined by solubilization in water-containing AOT (sodium bis(2-ethylhexyl)sulfosuccinate) reverse micelles has been investigated using (1)H NMR. NMR spectra reveal well-defined signals for the glucose hydroxyl groups that suggest slow chemical exchange between them and the water hydroxyl group. Using the EXSY (ZZ-exchange) method, the chemical exchange rate from water to glucose hydroxyl groups was measured for glucose in reverse micelles with size parameter w0=5, 10 and 20, at 25˚ C. The chemical exchange rates observed in the nanoconfined interior are dramatically slower (5-20 times) than observed for glucose in bulk aqueous solution at the same concentration as the micelle interior...
