Association between smoking and health outcomes in an economically deprived population: the Liverpool Lung Project

Background The association between smoking and several health outcomes among those from the most deprived communities in the UK has not previously been detailed. The aim of this study is to examine the impact of smoking on health outcomes specifically among a particularly deprived population in a developed country (Liverpool; one of the most deprived local authorities in England). Methods The Liverpool Lung Project recruited a prospective cohort of 8753 participants from across Liverpool, aged 45–79 years between 1998 and 2008. Participants were followed annually through the Hospital Episode Statistics until 31 January 2013. Logistic regression models were used to identify health outcomes of smoking. Results From our study population, 5195 were smokers and 3558 were non-smokers. Smoking was associated with male gender (OR 1.62, 95% CI 1.48 to 1.77), pneumonia (1.28, 95% CI 1.10 to 1.49), chronic obstructive pulmonary disease (1.30, 95% CI 1.14 to 1.48), emphysema (5.46, 95% CI 3.48 to 8.55), bronchitis (1.85, 95% CI 1.65 to 2.07), other cancers (1.69, 95% CI 1.44 to 1.99), lung cancer (6.0, 95% CI 3.72 to 9.69), diabetes (1.21, 95% CI 1.02 to 1.43) and cardiovascular disease (1.45, 95% CI 1.25 to 1.67). Conclusions Smokers from deprived backgrounds in Liverpool showed increased risk of developing pneumonia, emphysema, chronic obstructive pulmonary disease, bronchitis, lung cancer, other types of cancer, cardiovascular disease and diabetes. These findings are in line with the literature and may help to inform public health policies and ultimately work towards addressing smoking-related health inequalities.
Automatic Classification of Sub-Techniques in Classical Cross-Country Skiing Using a Machine Learning Algorithm on Micro-Sensor Data

The automatic classification of sub-techniques in classical cross-country skiing provides unique possibilities for analyzing the biomechanical aspects of outdoor skiing. This is currently possible due to the miniaturization and flexibility of wearable inertial measurement units (IMUs) that allow researchers to bring the laboratory to the field. In this study, we aimed to optimize the accuracy of the automatic classification of classical cross-country skiing sub-techniques by using two IMUs attached to the skier’s arm and chest together with a machine learning algorithm. The novelty of our approach is the reliable detection of individual cycles using a gyroscope on the skier’s arm, while a neural network machine learning algorithm robustly classifies each cycle to a sub-technique using sensor data from an accelerometer on the chest. In this study, 24 datasets from 10 different participants were separated into the categories training-, validation- and test-data. Overall, we achieved a classification accuracy of 93.9% on the test-data. Furthermore, we illustrate how an accurate classification of sub-techniques can be combined with data from standard sports equipment including position, altitude, speed and heart rate measuring systems. Combining this information has the potential to provide novel insight into physiological and biomechanical aspects valuable to coaches, athletes and researchers.
US military smallpox vaccination program experience.

CONTEXT The United States recently implemented smallpox vaccination of selected military personnel in a national program of preparedness against use of smallpox as a biological weapon. The resumption of smallpox vaccinations raises important questions regarding implementation and safety. OBJECTIVE To describe the US military smallpox vaccination program. DESIGN Descriptive study of the vaccination program from its inception on December 13, 2002, through May 28, 2003. SETTING US Department of Defense (DoD) fixed and field medical treatment facilities on multiple continents and ships at sea. SUBJECTS US service members and DoD civilian workers eligible for smallpox vaccination. MAIN OUTCOME MEASURES Numbers of vaccinations and rates of vaccination exemptions, symptoms, and adverse events. Data were collected via reports to headquarters and rigorous surveillance for sentinel events. RESULTS In 5.5 months, the DoD administered 450 293 smallpox vaccinations (70.5% primary vaccinees and 29.5% revaccinees). In 2 settings, 0.5% and 3.0% of vaccine recipients needed short-term sick leave. Most adverse events occurred at rates below historical rates. One case of encephalitis and 37 cases of acute myopericarditis developed after vaccination; all cases recovered. Among 19 461 worker-months of clinical contact, there were no cases of transmission of vaccinia from worker to patient, no cases of eczema vaccinatum or progressive vaccinia, and no attributed deaths. CONCLUSIONS Mass smallpox vaccinations can be conducted safely with very low rates of serious adverse events. Program implementation emphasized human factors: careful staff training, contraindication screening, recipient education, and attention to bandaging. Our experience suggests that broad smallpox vaccination programs may be implemented with fewer serious adverse events than previously believed.
Interspecific variation in sapling mortality in relation to growth and soil moisture

To examine the causes of landscape variation in forest community composition, we have quantified sapling mortality as a function of growth and soil moisture for seven dominant species in transition oak-northern hardwood forests of the northeastern USA. We located saplings in sites that encompassed a wide range of variation in soil moisture and light availability. In mesic conditions, the probability of mortality decays rapidly with increasing growth among shade tolerant species and more gradually among shade intolerant species: the rank order of survivorship at low growth rates is Tsuga canadensis>Fagus grandifolia>Acer saccharum>Fraxinus americana>Acer rubrum>Quercus rubra>Pinus strobus. The relationship between probability of mortality and growth does not vary with soil moisture among species insensitive to drought: Tsuga canadensis, Quercus rubra, and Pinus strobus. However, probability of mortality increases substantially with decreasing soil water availability for the other four species. Acer saccharum and Fagus grandifolia have high mortality rates under xeric conditions even when their growth is not suppressed. Acer rubrum and Fraxinus americana exhibited a steady but more gradual increase in the probability of mortality with decreasing soil moisture. Among the five deciduous hardwood species we examined there is a weak inverse relationship between the ability to survive growth suppression, a measure of shade tolerance, and the ability to survive in xeric conditions, a measure of drought tolerance. Tsuga canadensis, however, is tolerant of growth suppression and exhibits high survivorship in xeric conditions, while Pinus strobus is intolerant of growth suppression but insensitive to soil moisture. Species differences in water-dependent mortality are consistent with the species distributions across landscape gradients of soil water availability.
On a multicriteria clustering approach for attack attribution

We present a multicriteria clustering approach that has been developed to address a problem known as attack attribution in the realm of investigative data mining. Our method can be applied to a broad range of security data sets in order to get a better understanding of the root causes of the underlying phenomena that may have produced the observed data. A key feature of this approach is the combination of cluster analysis with a component for multi-criteria decision analysis. As a result, multiple criteria of interest (or attack features) can be aggregated using different techniques, allowing one to unveil complex relationships resulting from phenomena with eventually dynamic behaviors. To illustrate the method, we provide some empirical results obtained from a data set made of attack traces collected in the Internet by a set of honeypots during two years. Thanks to the application of our attribution method, we are able to identify several large-scale phenomena composed of IP sources that are linked to the same root cause, which constitute a type of phenomenon that we have called Misbehaving cloud (MC). An in-depth analysis of two instances of such clouds demonstrates the utility and meaningfulness of the approach, as well as the kind of insights we can get into the behaviors of malicious sources involved in these clouds.
Return to work following unintentional injury: a prospective follow-up study

Objective The aim of this study was to predict time off work following unintentional injuries due to accidents leading to hospital admission. Design Prospective 6-month follow-up study. Setting Department of Trauma Surgery of a University Hospital. Participants Consecutively recruited victims of unintentional injuries (n=221) hospitalised for a minimum of 32 h including two consecutive nights. All the participants were aged 18–65 years and were able to participate in an assessment within 30 days of the accident. Main outcome measures Interview-assessed number of days off work during the 6 months immediately following the accident. Results The patients’ subjective appraisals of (1) accident severity and (2) their ability to cope with the resulting injury and its job-related consequences predicted time off work following the accident beyond the impact of the objective severity of their injury and the type of accident involved. Conclusions The patients’ subjective appraisals of the accident severity and of their ability to cope with its consequences are highly relevant for return to work after accidents. Extending the findings from previous studies on severely injured and otherwise preselected accident victims, this seems to apply to the whole spectrum of patients hospitalised with unintentional injuries.
Moms and Media: Exploring the Effects of Online Communication on Infant Feeding Practices

ABSTRACT Using a survey of mothers with young children (N = 455), this study applies Fishbein and Ajzen’s reasoned action approach (RAA) to examine the relationship between online communication and infant feeding practices. Contrary to expectations, attitudes, perceived normative pressure, and perceived behavioral control (PBC) did not fully mediate the relationship between time spent online and behavioral intentions. Our findings indicate a significant, direct, negative association between time spent online and breastfeeding intentions In this article, theoretical and practical implications for health communication are discussed.
The Effects of Encumbrance and Mobility on Touch-Based Gesture Interactions for Mobile Phones

In this paper, we investigate the effects of mobility and encumbrance (holding objects such as shopping bags) on standard gestures commonly performed on touchscreens: tapping, dragging, spreading & pinching and rotating clockwise & anticlockwise when completed using a two-handed input posture. These one- and two- finger on-screen gesture inputs have become common but previous research has only examined tapping performance in everyday walking and encumbered situations. Therefore, a series of Fitts' Law style targeting tasks was designed to measure the performance of each gesture with users walking only and walking while carrying bags. The results showed that encumbrance and walking had a negative impact on each gesture in terms of accuracy except for rotational actions, which were performed well. Tapping and dragging both performed poorly which shows the input difficulties of single finger interactions when encumbered and on the move. Our findings will help designers choose the appropriate input techniques for future mobile user interfaces and apps in physically demanding contexts.
Impact of abundance weighting on the response of seed traits to climate and land use

1 Many studies have identified relationships between plant reproductive behaviour and environmental conditions. However, they have all been based on cross‐species analysis and take no account of the relative abundance of species with vegetation. 2 Using two reproductive traits – seed mass and dispersal vector – as examples, a range of previously identified relationships were tested using both unweighted and weighted‐by‐abundance data collected from land‐use transitions at 12 sites across Europe. 3 Seed mass was correlated positively with most measures of temperature (stronger relationships for unweighted data) and declined against measures of disturbance (stronger relationships with weighted data). It was not related consistently to measures of water availability. 4 There was some evidence that endozoochory was associated with damper environments, hoarding with drier ones and exozoochory with more fertile habitats. 5 Weighting reduced the slope of relationships between seed mass and environmental variables, possibly indicating that dominance within vegetation is determined by land use after the operation of a climatic filter. Fewer significant relationships were detected for weighted dispersal mechanisms compared to unweighted ones, indicating less difference of the dominants from other species with regard to this trait. 6 Synthesis. This analysis shows that weighting by abundance in the vegetation (compared to unweighted analysis) has a significant impact on the relationships between key species traits and a range of environmental parameters related to climate and land use, and that this impact was not consistent in its effects.
Randomized phase III trial of sequential chemoradiotherapy compared with concurrent chemoradiotherapy in locally advanced non-small-cell lung cancer: Groupe Lyon-Saint-Etienne d'Oncologie Thoracique-Groupe Français de Pneumo-Cancérologie NPC 95-01 Study.

PURPOSE We conducted a phase III study to compare the survival impact of concurrent versus sequential treatment with radiotherapy (RT) and chemotherapy (CT) in unresectable stage III non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Patients were randomly assigned to one of the two treatment arms. In the sequential arm, patients received induction CT with cisplatin (120 mg/m2) on days 1, 29, and 57, and vinorelbine (30 mg/m2/wk) from day 1 to day 78, followed by thoracic RT at a dose of 66 Gy in 33 fractions (2 Gy per fraction and 5 fractions per week). In the concurrent arm, the same RT was started on day 1 with two concurrent cycles of cisplatin 20 mg/m2/d and etoposide 50 mg/m2/d (days 1 to 5 and days 29 to 33); patients then received consolidation therapy with cisplatin 80 mg/m2 on days 78 and 106 and vinorelbine 30 mg/m2/wk from days 78 to 127. RESULTS Two hundred five patients were randomly assigned. Pretreatment characteristics were well balanced between the two arms. There were six toxic deaths in the sequential arm and 10 in the concurrent arm. Median survival was 14.5 months in the sequential arm and 16.3 months in the concurrent arm (log-rank test P = .24). Two-, 3-, and 4-year survival rates were better in the concurrent arm (39%, 25%, and 21%, respectively) than in the sequential arm (26%, 19%, and 14%, respectively). Esophageal toxicity was significantly more frequent in the concurrent arm than in the sequential arm (32% v 3%). CONCLUSION Although not statistically significant, clinically important differences in the median, 2-, 3-, and 4-year survival rates were observed, with a trend in favor of concurrent chemoradiation therapy, suggesting that is the optimal strategy for patients with locally advanced NSCLC.
N-Acetylcysteine Improves the Viability of Human Hepatocytes Isolated from Severely Steatotic Donor Liver Tissue

Hepatocyte transplantation is dependent on the availability of good quality human hepatocytes isolated from donor liver tissue. Hepatocytes obtained from livers rejected for transplantation on the grounds of steatosis are often of low viability and not suitable for clinical use. The aim of this study was to evaluate the effects of the antioxidant N-acetylcysteine (NAC) on the function of hepatocytes isolated from steatotic donor livers. Human hepatocytes were isolated from 10 severely steatotic (>60%) donor livers rejected for transplantation. The left lateral segment of the donor liver was dissected into two equal size pieces and randomized to NAC or control. NAC (5 mM) was added to the first perfusion buffer of the standard collagenase digestion technique. Cells from tissues perfused with NAC had a significantly higher mean viability (81.1 ± 1.7% vs. 66.0 ± 4.7%; p = 0.003) and cell attachment (1.08 ± 0.26 vs. 0.67 ± 0.18 OD units; p = 0.012). Addition of NAC during isolation of human hepatocytes from steatotic donor liver tissue significantly improved the outcome of cell isolation. Further studies are needed to investigate the mechanism(s) of this effect. Incorporation of NAC in the hepatocyte isolation protocol could increase the availability of hepatocytes for transplantation.
Activated Signal Transduction Kinases Frequently Occupy Target Genes

Cellular signal transduction pathways modify gene expression programs in response to changes in the environment, but the mechanisms by which these pathways regulate populations of genes under their control are not entirely understood. We present evidence that most mitogen-activated protein kinases and protein kinase A subunits become physically associated with the genes that they regulate in the yeast (Saccharomyces cerevisiae) genome. The ability to detect this interaction of signaling kinases with target genes can be used to more precisely and comprehensively map the regulatory circuitry that eukaryotic cells use to respond to their environment.
Inhibition of NMDA‐induced striatal dopamine release and behavioral activation by the neuroactive steroid 3α‐hydroxy‐5β‐pregnan‐20‐one hemisuccinate

Our laboratory has previously shown that the synthetic neuroactive steroid 3α‐hydroxy‐5β‐pregnan‐20‐one hemisuccinate (3α5βHS) is a negative modulator of NMDA receptors in vitro. Similarly, 3α5βHS exhibits rapid sedative, analgesic, anticonvulsive, and neuroprotective effects in vivo. Here we report a study designed to investigate whether a negatively charged neuroactive steroid, 3α5βHS, modulates the action of NMDA receptors in vivo. Our results indicate that peripherally administered 3α5βHS enters the CNS and inhibits NMDA‐mediated motor activity and dopamine release in the rat striatum. The increase in motor activity induced by intrastriatal microinjection of NMDA was blocked by the systemic administration of 3α5βHS and the NMDA‐induced increase in extracellular dopamine in the striatum was also attenuated by both systemically administered and intrastriatally administered (by in vivo microdialysis) 3α5βHS. These data indicate that 3α5βHS acts through striatal NMDA receptors in vivo. When taken together, these results suggest that neuroactive steroids may prove to be effective in the treatment of neurological and psychiatric disorders involving over‐stimulation of NMDA receptors in the mesotelencephalic dopamine system.
Visual Storytelling

We introduce the first dataset for sequential vision-to-language, and explore how this data may be used for the task of visual storytelling. The first release of this dataset, SIND1 v.1, includes 81,743 unique photos in 20,211 sequences, aligned to both descriptive (caption) and story language. We establish several strong baselines for the storytelling task, and motivate an automatic metric to benchmark progress. Modelling concrete description as well as figurative and social language, as provided in this dataset and the storytelling task, has the potential to move artificial intelligence from basic understandings of typical visual scenes towards more and more human-like understanding of grounded event structure and subjective expression.
The elusive atomic register

We present a construction of a single-writer, multiple-reader atomic register from single-writer, single-reader atomic registers. The complexity of our construction is asymptotically optimal; <italic>O(M<supscrpt>2</supscrpt> + MN)</italic> shared single-writer, single-reader safe bits are required to construct a single-writer, M-reader, N-bit atomic register.
Endometriosis‐related malignancies

The purpose of this study is to describe the clinical findings, treatment, and outcome of patients with endometriosis-related cancers. Patients meeting Sampson and Scott's criteria for cancer associated with endometriosis in the Sacramento region were identified by chart review and pathology reports. Twenty-seven patients were identified with endometriosis-related malignancies (mean age 51.4 years). The site of origin was ovary in 17 (63.0%) and extra-ovarian in 10 (37%) including vagina, fallopian tube or mesosalpinx, pelvic sidewall, colon, and parametrium. The pattern of spread was local in five (18.5%), regional in 20 (74.1%) and distant in two (7.4%). Six patients had taken unopposed estrogen replacement (mean duration 23.4 years) and all six had extragonadal disease. Surgical procedures included hysterectomy, salpingo-oophorectomy, radical local excision, partial colectomy, and surgical staging. Eighteen patients received postoperative chemotherapy since the majority of patients had ovarian involvement. Fifteen patients received regional radiation therapy. Nineteen patients are without evidence of recurrence (70.4%, mean follow-up of 31 months). Endometriosis-related malignancies have a favorable prognosis. Extragonadal disease was commonly associated with unopposed estrogen replacement therapy. The predominance of local and regional disease strongly influence the application of treatment modalities.
Preparação e caracterização de nanocompósitos poliméricos baseados em quitosana e argilo minerais

In this work nanocomposites based on chitosan and different clays were prepared using polyethyleneglycol (PEG) as plasticizer. The samples obtained were characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), thermogravimetric analysis (TGA/DTG) and by mechanical characterization (tensile test) with the aim of investigating the interactions between chitosan and clay. The nanocomposite films prepared using sodium bentonite (Ben) showed an increase of 81.2% in the maximum tensile stress values and a decrease of 16.0% in the Young's modulus when compared to the chitosan with PEG (QuiPEG) films, evidencing that the introduction of the clay into the polymer matrix provided a more flexible and resistant film, whose elongation at break was 93.6% higher than for the QuiPEG film.
Immunohistochemical study on ADAM33 in sinonasal inverted papillomas and squamous cell carcinomas of the larynx

Introduction ADAM33 protein is a member of the family of transmembrane glycoproteins composed of multidomains. Members of the ADAM family have different activities, such as proteolysis and adhesion, making them good candidates to mediate the extracellular matrix remodeling and changes in cellular adhesion that characterize certain pathologies and cancer development. Material and methods The immunohistochemical method was used to examine the immunoexpression of ADAM33 in 39 formalin-fixed, paraffin-embedded tissue specimens of sinonasal inverted papillomas (IP), 44 laryngeal squamous cell carcinomas (GI grade = 11, GII grade = 33) and 14 disease-free tissue specimens as a control. Results The immunoexpression of ADAM33 was localized in the epithelial cells, mesenchymal cells of the vessels and infrequently in the stromal cells. The majority of the ADAM33 was localized intracellularly, although membrane immunoexpression was also noted. All epithelial and vascular staining scores were found to be significantly increased in GI and GII grades of laryngeal cancer compared with controls (p < 0.001) and IP (p < 0.001). No statistically significant differences were found in immunoexpression of ADAM33 between GI and GII tumors. The immunoexpression of ADAM33 was significantly higher in IP patients than in controls (p < 0.02). Conclusions Our findings suggest that ADAM33 could potentially contribute to tumorigenesis of the laryngeal and sinonasal region.
