A new technique of bladder neck reconstruction during radical prostatectomy in patients with prostate cancer

PURPOSE
To evaluate continence after radical prostatectomy in prostate cancer patients, in whom a new method of the bladder neck reconstruction (BNR) using deep dorsal stitch was implemented (deep single stitch through all bladder layers directly dorsal to the bladder opening after ″ tennis racket″ reconstruction) and to provide justification for its use by means of anatomical study in cadavers.


MATERIAL AND METHODS
Open radical retropubic prostatectomy was performed in 84 patients: 39 patients with a new BNR method used to improve continence and control group of 45 patients with standard ″tennis racket″ BNR. Median follow-up was 14 months in control group and 12 months in study group. Continence recovery was accessed early postoperatively and every 3 months thereafter. Anatomical study was performed on 2 male fresh cadavers reproducing two different BNR techniques to clarify any underlying continence related mechanisms.


RESULTS
Patients with new BNR achieved full continence significantly faster (p=0.041), but the continence rates after 12 months were similar between groups. The severity of incontinence up to month 9 was significantly reduced in BNR group. The anastomotic stricture rate was not affected. Applying new BNR to the cadaver model revealed effects on early continence, namely presence of proximal passive closure mechanism in area of bladder neck.


CONCLUSIONS
Continence in patients with the new BNR method using deep dorsal stitch recovered significantly faster. Moreover, a reduced grade of residual incontinence was documented. The effect was non-significant at month 12 of follow-up, meaning that only early effect was present.
Adaptive landmark recommendations for travel planning: Personalizing and clustering landmarks using geo-tagged social media

When travelers plan trips, landmark recommendation systems that consider the trip properties will conveniently aid travelers in determining the locations they will visit. Because interesting locations may vary based on the traveler and the situation, it is important to personalize the landmark recommendations by considering the traveler and the trip. In this paper, we propose an approach that adaptively recommends clusters of landmarks using geo-tagged social media.We first examine the impact of a trip’s spatial and temporal properties on the distribution of popular places through large-scale data analyses. In our approach, we compute the significance of landmarks for travelers based on their trip’s spatial and temporal properties. Next, we generate clusters of landmark recommendations, which have similar themes or are contiguous, using travel trajectory histories. Landmark recommendation performances based on our approach are evaluated against several baseline approaches. Our approach results in increased accuracy and satisfaction compared with the baseline approaches. Through a user study, we also verify that our approach is applicable to lesser-known places and reflects local events as well as seasonal changes. © 2014 Elsevier B.V. All rights reserved.
Are Sitting Occupations Associated with Increased All-Cause, Cancer, and Cardiovascular Disease Mortality Risk? A Pooled Analysis of Seven British Population Cohorts

BACKGROUND
There is mounting evidence for associations between sedentary behaviours and adverse health outcomes, although the data on occupational sitting and mortality risk remain equivocal. The aim of this study was to determine the association between occupational sitting and cardiovascular, cancer and all-cause mortality in a pooled sample of seven British general population cohorts.


METHODS
The sample comprised 5380 women and 5788 men in employment who were drawn from five Health Survey for England and two Scottish Health Survey cohorts. Participants were classified as reporting standing, walking or sitting in their work time and followed up over 12.9 years for mortality. Data were modelled using Cox proportional hazard regression adjusted for age, waist circumference, self-reported general health, frequency of alcohol intake, cigarette smoking, non-occupational physical activity, prevalent cardiovascular disease and cancer at baseline, psychological health, social class, and education.


RESULTS
In total there were 754 all-cause deaths. In women, a standing/walking occupation was associated with lower risk of all-cause (fully adjusted hazard ratio [HR] = 0.68, 95% CI 0.52-0.89) and cancer (HR = 0.60, 95% CI 0.43-0.85) mortality, compared to sitting occupations. There were no associations in men. In analyses with combined occupational type and leisure-time physical activity, the risk of all-cause mortality was lowest in participants with non-sitting occupations and high leisure-time activity.


CONCLUSIONS
Sitting occupations are linked to increased risk for all-cause and cancer mortality in women only, but no such associations exist for cardiovascular mortality in men or women.
Oil Shocks and External Balances

This paper estimates the effects of demand and supply shocks in the global crude oil market on several measures of oil exporters’ and oil importers’ external balance, including the oil trade balance, the non-oil trade balance, the current account, capital gains, and changes in net foreign assets (NFA). Our first result is that the effect of oil demand and supply shocks on the merchandise trade balance and the current account, which depending on the source of the shock can be large, depends critically on the response of the non-oil trade balance. Our estimates of the response of the non-oil trade balance provide a benchmark for models of the international transmission of these shocks under incomplete markets. Second, we document the presence of potentially large and systematic valuation effects in response to these shocks. Valuation effects overall tends to cushion the effect of oil demand and supply shocks on the NFA positions of oil exporters and oil importers. Third, we quantify the overall importance of oil-market specific demand and supply shocks for external balances. We find, for example, that these shocks jointly account for about half of the variation in oil exporters’ changes in NFA, whereas demand shocks associated with the global business cycle account for an additional one third.

A 77-79-GHz Doppler Radar Transceiver in Silicon

This paper presents the first 77 GHz single-chip direct-conversion transceiver in silicon. The transceiver, fabricated in a 0.13 mum SiGe BiCMOS technology with fT/fMAX of 170/200 GHz, consumes 740 mW, and occupies 1.3 mm x 0.9 mm. The receiver achieves 25.6 dB conversion gain, 9 dB noise figure, 90 dB dynamic range, and an IP1dB of -24 dBm. The transmitter provides +5.8 dBm of saturated output power at 77 GHz, and a divide14, static frequency divider is included on-die. A tuned, 77 GHz clock distribution network is used to distribute the VCO signal to the divider, power amplifier, and down-conversion mixer. Successful detection of a Doppler shift of 55 Hz at a range of 4 m is shown. The phase noise at IF is shown to be superior to the VCO, suggesting noise correlation between the transmitter and receiver.
The Koobface botnet and the rise of social malware

As millions of users flock to online social networks, sites such as Facebook and Twitter are becoming increasingly attractive targets for spam, phishing, and malware. The Koobface botnet in particular has honed its efforts to exploit social network users, leveraging zombies to generate accounts, befriend victims, and to send malware propagation spam. In this paper, we explore Koobface's zombie infrastructure and analyze one month of the botnet's activity within both Facebook and Twitter. Constructing a zombie emulator, we are able to infiltrate the Koobface botnet to discover the identities of fraudulent and compromised social network accounts used to distribute malicious links to over 213,000 social network users, generating over 157,000 clicks. Despite the use of domain blacklisting services by social network operators to filter malicious links, current defenses recognize only 27% of threats and take on average 4 days to respond. During this period, 81% of vulnerable users click on Koobface spam, highlighting the ineffectiveness of blacklists.
Speaker-independent speech recognition based on tree-structured speaker clustering

We have already proposed the application of tree-structured speaker clustering to supervised speaker adaptation. This paper proposes its application to unsupervised speaker adaptation and speakerindependent (SI) speech recognition. This clustering involves the selection of a speaker cluster from among multiple reference speaker clusters arranged in a tree structure. Cluster selection, unlike parameter training, enables quick adaptation using only a small amount of training data. This method was applied to a hidden Markov network (HMnet) and evaluated in Japanese phoneme and phrase recognition experiments. Results show effective unsupervised speaker adaptation using only 5 s calibration speech. In the SI speech recognition experiments, the method reduced the error rate by 8·5% compared with the conventional speaker-independent speech recognition method.  1996 Academic Press Limited
Visual Assessment of Relative Apical Sparing Pattern Is More Useful Than Quantitative Assessment for Diagnosing Cardiac Amyloidosis in Borderline or Mildly Increased Left Ventricular Wall Thickness.

BACKGROUND
Relative apical sparing pattern of longitudinal strain (RapSP-LS) was suggested in advanced cardiac amyloidosis (CA). It is unclear whether it is present in less advanced CA.


METHODS AND RESULTS
Patients with presumptive diagnosis of CA and mean left ventricular wall thickness (LVWT) ≤14 mm were recruited. Apart from RapSP-LS visually identified, relative apical longitudinal strain index (RapLSI) was defined as [average apical LS/(average basal LS+average mid-ventricle LS)]. Among 119 patients included, 47 were finally diagnosed with CA. RapLSI was higher in the CA group compared to other causes of increased mean LVWT (P<0.001), but with a significant range of overlap noted. In contrast, RapSP-LS visually assessed was noted in most CA patients (31/47, 66.0%) except in those with preserved LV ejection fraction, normal LVWT, and mildly decreased global LS, suggesting least advanced CA. On multivariate analysis of the added diagnostic role of RapSP-LS or RapLSI on top of clinical, electrocardiographic, and conventional echocardiographic parameters, addition of RapLSI produced only borderline increase in area under the curve of the multivariate model (P=0.05), whereas addition of RapSP-LS significantly increased it (P<0.001).


CONCLUSIONS
Visual identification of RapSP-LS is useful in terms of added diagnostic value compared with quantitative calculation of RapLSI. Its clinical application, however, should be used with caution in patients with less advanced CA.
Effects on advanced materials: results of the STS-8 EOIM (effects of oxygen interaction with materials) experiment

Abstract : A variety of materials were exposed to the low Earth orbit space environment on shuttle flight STS-8 as a part of NASA's Effects of Oxygen Atoms Interaction with Materials experiment.

Energy intake and obesity: Ingestive frequency outweighs portion size

Energy intake is a function of the quantity of energy consumed per ingestive event and the number of these events. The marked increase of energy intake and body weight over the past 35 years indicates that there has been poor precision in the reciprocity of these two facets of intake. With recent study of the associations between gut "satiation" peptides and energy intake, there has been an emphasis on the contribution of portion size to positive energy balance. However, this orientation may not appropriately weight the contribution of ingestive frequency. Gut peptides are not purely satiation factors and metabolic and environmental cues may more strongly guide the onset and number of ingestive events. Evidence is presented that while both portion size and ingestive frequency have increased in the population, the latter may be more problematic for weight gain. The magnitude and time course of increments in ingestive frequency map better onto energy intake and BMI trends than changes of portion size. This may occur, in part, because dietary compensation and thermogenic effects are weaker for increases in ingestive frequency than portion size. Though not to the exclusion of consideration of portion size effects, improved weight management may be achieved with greater attention to the drivers of eating and drinking frequency.

Analytical mapping of opinion mining and sentiment analysis research during 2000-2015

The new transformed read-write Web has resulted in a rapid growth of user generated content on the Web resulting into a huge volume of unstructured data. A substantial part of this data is unstructured text such as reviews and blogs. Opinion mining and sentiment analysis (OMSA) as a research discipline has emerged during last 15 years and provides a methodology to computationally process the unstructured data mainly to extract opinions and identify their sentiments. The relatively new but fast growing research discipline has changed a lot during these years. This paper presents a scientometric analysis of research work done on OMSA during 20 0 0–2016. For the scientometric mapping, research publications indexed in Web of Science (WoS) database are used as input data. The publication data is analyzed computationally to identify year-wise publication pattern, rate of growth of publications, types of authorship of papers on OMSA, collaboration patterns in publications on OMSA, most productive countries, institutions, journals and authors, citation patterns and an year-wise citation reference network, and theme density plots and keyword bursts in OMSA publications during the period. A somewhat detailed manual analysis of the data is also performed to identify popular approaches (machine learning and lexicon-based) used in these publications, levels (document, sentence or aspect-level) of sentiment analysis work done and major application areas of OMSA. The paper presents a detailed analytical mapping of OMSA research work and charts the progress of discipline on various useful parameters. © 2016 Elsevier Ltd. All rights reserved.
Characterization of probiotic Escherichia coli isolates with a novel pan-genome microarray

Microarrays have recently emerged as a novel procedure to evaluate the genetic content of bacterial species. So far, microarrays have mostly covered single or few strains from the same species. However, with cheaper high-throughput sequencing techniques emerging, multiple strains of the same species are rapidly becoming available, allowing for the definition and characterization of a whole species as a population of genomes - the 'pan-genome'. Using 32 Escherichia coli and Shigella genome sequences we estimate the pan- and core genome of the species. We designed a high-density microarray in order to provide a tool for characterization of the E. coli pan-genome. Technical performance of this pan-genome microarray based on control strain samples (E. coli K-12 and O157:H7) demonstrated a high sensitivity and relatively low false positive rate. A single-channel analysis approach is robust while allowing the possibility for deriving presence/absence predictions for any gene included on our pan-genome microarray. Moreover, the array was highly sufficient to investigate the gene content of non-pathogenic isolates, despite the strong bias towards pathogenic E. coli strains that have been sequenced so far. This high-density microarray provides an excellent tool for characterizing the genetic makeup of unknown E. coli strains and can also deliver insights into phylogenetic relationships. Its design poses a considerably larger challenge and involves different considerations than the design of single strain microarrays. Here, lessons learned and future directions will be discussed in order to optimize design of microarrays targeting entire pan-genomes.
A randomized trial of dalteparin compared with ibuprofen for the treatment of superficial thrombophlebitis

Background: Superficial thrombophlebitis can produce pain and result in a deep vein thrombosis (DVT) if not treated. Conservative therapies including prescription of nonsteroidal anti-inflammatory drugs (NSAID) andheat have been standard care. Recently, studies have been published reporting efficacy and safety of low-molecular-weight heparin for the treatment of superficial thrombophlebitis. However, there are few comparative trials to conservative therapy. We studied the effectiveness and safety of treatment with dalteparin compared with ibuprofen in patients with confirmed superficial thrombophlebitis. Methods: Consecutive patients were randomized to receive daily dalteparin vs. ibuprofen three times daily for up to 14 days. The primary outcome measure was the incidence of extension of thrombus or new symptomatic venous thromboembolism during the 14-day and 3-month follow-up period. The secondary outcome was a reduction in pain. The outcome measure of safety was the incidence of major and minor bleeding.Results:Of 302 consecutive patients screened, 72 were enrolled. Four patients receiving ibuprofen compared with no patients receivingdalteparin had thrombus extensionat 14 days (P = 0.05), however, there was no difference in thrombus extension at 3 months. Both treatments significantly reduced pain. Therewere no episodes ofmajor orminor bleeding during the treatment period.Conclusions:Dalteparin is superior to the NSAID ibuprofen in preventing extension of superficial thrombophlebitis during the 14-day treatment period with similar relief of pain and no increase in bleeding. However, questions concerning the optimal treatment duration should be explored in future trials.
SDN AND ITS USE-CASES-NV AND NFV A State-ofthe-Art Survey

Three concepts (a) network programmability by clear separation of data and control planes and (b) sharing of network infrastructure to provide multitenancy, including traffic and address isolation, in large data center networks and (c) replacing the functions that traditionally run on a specialized hardware, with the software-realizations that run on commodity servers have gained lot of attention by both Industry and research-community over past few years. These three concepts are broadly referred as software defined networking (SDN), network virtualization (NV) and network functions virtualization (NFV). This paper presents a thorough study of these three concepts, including how SDN technology can complement the network virtualization and network functions virtualization. SDN, is about applying modularity to network control, which gives network designer the freedom to re-factor the control plane. This modularity has found its application in various areas including network virtualization. This work begins with the survey of software defined networking, considering various perspectives. The survey of SDN is followed by discussing how SDN plays a significant role in NV and NFV. Finally, this work also attempts to explore future directions in SDN based on current trends.

Ten-year results of a three-arm prospective cohort study on implants in periodontally compromised patients. Part 1: implant loss and radiographic bone loss.

OBJECTIVES
The aim of this study was to compare the long-term outcomes of implants placed in patients treated for periodontitis periodontally compromised patients (PCP) and in periodontally healthy patients (PHP) in relation to adhesion to supportive periodontal therapy (SPT).


MATERIAL AND METHODS
One hundred and twelve partially edentulous patients were consecutively enrolled in private specialist practice and divided into three groups according to their initial periodontal condition: PHP, moderate PCP and severe PCP. Perio and implant treatment was carried out as needed. Solid screws (S), hollow screws (HS) and hollow cylinders (HC) were installed to support fixed prostheses, after successful completion of initial periodontal therapy (full-mouth plaque score <25% and full-mouth bleeding score <25%). At the end of treatment, patients were asked to follow an individualized SPT program. At 10 years, clinical measures and radiographic bone changes were recorded by two calibrated operators, blinded to the initial patient classification.


RESULTS
Eleven patients were lost to follow-up. During the period of observation, 18 implants were removed because of biological complications. The implant survival rate was 96.6%, 92.8% and 90% for all implants and 98%, 94.2% and 90% for S-implants only, respectively, for PHP, moderate PCP and severe PCP. The mean bone loss was 0.75 (+/- 0.88) mm in PHP, 1.14 (+/- 1.11) mm in moderate PCP and 0.98 (+/- 1.22) mm in severe PCP, without any statistically significant difference. The percentage of sites, with bone loss > or =3 mm, was, respectively, 4.7% for PHP, 11.2% for moderate PCP and 15.1% for severe PCP, with a statistically significant difference between PHP and severe PCP (P<0.05). Lack of adhesion to SPT was correlated with a higher incidence of bone loss and implant loss.


CONCLUSION
Patients with a history of periodontitis presented a lower survival rate and a statistically significantly higher number of sites with peri-implant bone loss. Furthermore, PCP, who did not completely adhere to the SPT, were found to present a higher implant failure rate. This underlines the value of the SPT in enhancing the long-term outcomes of implant therapy, particularly in subjects affected by periodontitis, in order to control reinfection and limit biological complications.
Risk factors for falls and injuries in a long-term care facility in Ontario.

OBJECTIVE
To identify risk factors for falls and injuries among seniors living in a long-term care facility.


METHOD
Case-control study of 335 residents living at St. Joseph's Villa, Dundas, Ontario. Cases were defined as residents who fell between July 1, 1996 and June 30, 1997; controls were those who did not fall. To identify risk factors for injury, cases were defined as those with completed incident injury forms and controls as those without.


RESULTS
The most important risk factors for falls included: having fallen in the past three months; residing in a secured unit; living in the facility for two or more years; having the potential to cause injury to others; and having an illness, disease or behaviour that may cause a fall. The most important risk factor for injury among those who fell was altered mental state.


CONCLUSION
The risk factors identified may be helpful to those planning falls prevention initiatives within long-term care settings.
