Clinical Results of Lymphography in Cancer of the Uterine Cervix. A Retrospective Study of 542 Consecutive, Unselected Patients

From 1961 to 1976, 542 patients were evaluated with foot lymphography for cancer of the cervix at the Istituto Nazionale Tumori of Milan. A group of 341 patients had lymphangiography as part of the initial diagnostic work-up. The overall incidence of positive examinations was 25% (9% stage I, 29% stage II, 46% stage III, 50% stage IV). In the 115 patients who had pelvic surgery the overall diagnostic accuracy of lymphography was 88%, with 2 false positive and 12 false negative reports. A second group of 90 patients was evaluated in the follow-up without clinical evidence of disease, and the incidence of metastases was 17%. Finally, a group of 111 patients was studied for recurrence, and in this group the incidence of metastases was 51%. As regards site of involvement, the external iliac chains were involved in 93 to 96% of the cases, the common iliac in 34 to 79%, and the para-aortic in 17 to 36% in the different clinical conditions. The highest incidence of para-aortic metastases was found in the clinically initial stages (I and II) and in the recurrences. The lymphographic involvement of the retroperitoneal nodes was usually limited to a single region (41%) or two regions (37%). Only in 22% of the positive cases was a diffuse involvement of the retroperitoneal node chains evident.
Performance comparison of target localization for active sonar systems

The performance comparison of target localization for active sonar and effective fusion algorithms for target localization of multistatic sonar is investigated. Active sonar can be categorized into monostatic, bistatic, and multistatic, depending on the number of receiver elements. Target localization performance depends on the system configuration. The target localization performance of the monostatic, bistatic, and multistatic sonar systems is compared assuming that each element can receive both range and azimuth information of the target. In addition, we propose the weighted least square (WLS) algorithm, which incorporates judicial weighting to the conventional least square (LS) method, and an efficient sensor arrangement rule for target localization in the multistatic sonar system. The representative experimental results demonstrate that the target localization performance of multistatic sonar configuration is superior in terms of root-mean-square error (RMSE), to monostatic sonar and bistatic sonar by 35.98% and 37.45%, respectively, while the proposed WLS algorithm showed an improvement of 2.27% compared with the LS method.
Multinational comparisons of stroke epidemiology. Evaluation of case ascertainment in the WHO MONICA Stroke Study. World Health Organization Monitoring Trends and Determinants in Cardiovascular Disease.

BACKGROUND AND PURPOSE As part of the WHO MONICA Project (World Health Organization Monitoring Trends and Determinants in Cardiovascular Disease), mortality and incidence rates of acute stroke in 14 centers covering 21 populations from 11 countries were compared. METHODS In this report, coverage and quality of the MONICA stroke registers were evaluated on five key indicators using data submitted to the MONICA Data Center. RESULTS A low ratio of MONICA stroke register to routine statistics of stroke mortality and a low proportion of nonfatal out-of-hospital events were the most common biases; they indicate that identifications of fatal cases and/or case finding of nonfatal events occurring outside the hospital were inadequate in many MONICA centers. In 10 populations, the data quality analyses suggested that clarification of possible biases would be needed before these populations can be included in a comparative study. Data from the remaining 11 populations meet the data quality standards for multinational comparisons with respect to case ascertainment. CONCLUSIONS These results show that multinational comparisons of stroke incidence involve considerable problems in developing and maintaining appropriate standards of data quality. However, after considerable efforts to ensure quality, comparisons of stroke data within the MONICA Project are possible among a large number of the MONICA populations. Our observations also indicate that results from multinational comparisons of stroke mortality based on routine statistics must be interpreted with caution.
Reply re: "Anterior Segment Ischemia and Retinochoroidal Vascular Occlusion After Intralesional Steroid Injection".

then injecting small quantities of steroid, while advancing the syringe. We believe, and have previously published on this topic, that a potentially safer method involves applying the chalazion clamp tightly to the anesthetized eyelid, followed by steroid injection, which should minimize the occurrence of steroid embolic phenomena. Finally, not only is ocular steroid embolization devastating for the patient and the surgeon, but there is no recognized effective treatment. Thus, we continue to maintain that prevention of this disaster by clamping the eyelid may be an effective and appropriate prevention strategy.
Type 3 fimbriae of Klebsiella sp.: molecular characterization and role in bacterial adhesion to plant roots

Type 3 fimbriae of Klebsiella were purified and characterized. The fimbriae were 4 to 5 nm in diameter and 0.5 to 2 microns long. In sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the fimbrillin had an apparent molecular weight of 23,500, and it differed from enterobacterial type 1 fimbrillins in its amino acid composition. Hydrophobic amino acids comprised 33.6% of all amino acids in the fimbrillin, which lacked cystine, phenylalanine, and arginine. Serologically, the type 3 fimbriae were also distinct from the type 1 fimbriae. Purified type 3 fimbriae agglutinated tannin-treated human blood group O erythrocytes; this confirms the role of type 3 fimbriae as hemagglutinins. Purified 125I-labeled type 3 fimbriae bound to the roots of Poa pratensis, and this binding could be inhibited by Fab fragments to the purified fimbriae. Anti-type 3 fimbriae Fab fragments also inhibited bacterial adhesion to plant roots. These results demonstrate that type 3 fimbriae mediate adhesion of klebsiellas to plant roots. Eight nitrogen-fixing strains of Klebsiella also produced type 3 fimbriae when grown under anaerobic nitrogen fixation conditions. It is proposed that type 3 fimbriae are involved in the establishment of the plant-bacterium association concerning nitrogen-fixing Klebsiella strains.
Stressors and affective states among professional rugby union players

The purpose of the present study was to examine (a) the sources of sport and non‐sport stress and their associated symptoms on rest days, training days, and match days and (b) the temporal aspects of sources and symptoms of stress and affective states. Professional male rugby union players (n=16) completed the Daily Analysis of Life Demands in Athletes (DALDA) and the Activation Deactivation Adjective Check List (AD ACL) for 28 days. On match days players reported that few stressors were “worse than normal. ” Most stressors were “worse than normal” on training days followed by rest days and more stressors were “worse than normal” on the day after a match than on match days. Further, players reported an unpleasant, low activation state across the three analysis days, suggesting they were in an overtrained state. The findings of this study demonstrate that professional rugby players experience negative affect and a multitude of sport and non‐sport stressors. Early detection of stressors and negative affective states could help prevent symptoms of overtraining and burnout and facilitate optimal training and sporting performance. Coaches and practitioners are encouraged to integrate the DALDA and AD ACL in their training and performance monitoring regimes.
Effectiveness of community health worker training programmes for cardiovascular disease management in low-income and middle-income countries: a systematic review

Introduction Community health workers (CHWs) are increasingly being tasked to prevent and manage cardiovascular disease (CVD) and its risk factors in underserved populations in low-income and middle-income countries (LMICs); however, little is known about the required training necessary for them to accomplish their role. This review aimed to evaluate the training of CHWs for the prevention and management of CVD and its risk factors in LMICs. Methods A search strategy was developed in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and five electronic databases (Medline, Global Health, ERIC, EMBASE and CINAHL) were searched to identify peer-reviewed studies published until December 2016 on the training of CHWs for prevention or control of CVD and its risk factors in LMICs. Study characteristics were extracted using a Microsoft Excel spreadsheet and quality assessed using Effective Public Health Practice Project’s Quality Assessment Tool. The search, data extraction and quality assessment were performed independently by two researchers. Results The search generated 928 articles of which 8 were included in the review. One study was a randomised controlled trial, while the remaining were before–after intervention studies. The training methods included classroom lectures, interactive lessons, e-learning and online support and group discussions or a mix of two or more. All the studies showed improved knowledge level post-training, and two studies demonstrated knowledge retention 6 months after the intervention. Conclusion The results of the eight included studies suggest that CHWs can be trained effectively for CVD prevention and management. However, the effectiveness of CHW trainings would likely vary depending on context given the differences between studies (eg, CHW demographics, settings and training programmes) and the weak quality of six of the eight studies. Well-conducted mixed-methods studies are needed to provide reliable evidence about the effectiveness and cost-effectiveness of training programmes for CHWs.
Towards an EMG Controlled Prosthetic Hand Using a 3D Electromagnetic Positioning System

This paper proposes a novel method of using electromyographic (EMG) potentials generated by the forearm muscles during hand and finger movements to control an artificial prosthetic hand worn by an amputee. Surface EMG sensors were used to record the forearm EMG potential signal via a PC sound card, meanwhile, a novel 3D electromagnetic positioning system together with a data-glove mounted with 11 miniature electromagnetic sensors was used to acquire human hand motion in real time. The synchronized measurement of hand posture and EMG signal are stored as prototypes, in the format of a series of data frames, each comprising a set of positional and orientation posture data and a set of EMG data. A graphical hand model was also generated to visualize the real time hand movement. Further, we propose that only the EMG measurement device be attached to the forearm muscle of the prosthetic hand user. Candidate sets of EMG data acquired in real time will be compared with stored prototypes within each data frame using a pattern recognition approach. Subsequently, the most likely posture data set in this frame will be considered as the numerical expression of the current hand shape and used to control a robotic hand so that it carries out the user's desire. With a two-channel EMG measurement device, we first apply frequency analysis on the conditioned raw EMG signal. Then, pattern recognition techniques may be applied to identify the most closely aligned spectrum generated from the data recorded by the dual channel EMG measurement device. Alternatively, when a multi-channel (5-6) EMG measurement device is developed, pattern recognition can be applied on the amplitude of EMG signals to identify the most likely EMG signal distributions. This approach offers several advantages over existing methods. Firstly, it will simplify the classification procedure, saving computational time, secondly, it will reduce the requirement for the optimization process, and finally it will increase the number of recognizable hand shapes and subsequently improve the dexterity of the prosthetic hand and the quality of life for amputees. The database of EMG prototypes could be employed to optimize the accuracy of the system within a machine learning paradigm. By making a range of EMG prototype databases available prosthetic hand users could train themselves to use their prosthesis using the visual reference of the real time hand model to provide feedback
Part and Whole in Pictorial Relief

What are “natural parts” of pictorial reliefs? Intuitively, and suggested by common lore from the visual arts, they are the bulges that stick out toward the observer. Each such bulge contains a (locally) nearest point and is bounded by one or (usually) more curvilinear ruts. The latter meet in “passes” or saddle points. This divides the relief into “natural districts”. From a formal analysis one knows that reliefs can be divided into “hill districts” or “dale districts”, these two “natural” parcellations being fully distinct. We report empirical results that strongly suggest that visual awareness is based on a partition in bulges, which are mutually only weakly connected. Such a notion immediately explains why inverted reliefs or surfaces illuminated from below appear so different as to be mutually not recognizable.
Modified CLIP with objective liver reserve assessment retains prognosis prediction for patients with advanced hepatocellular carcinoma

The Cancer of the Liver Italian Program (CLIP) score is a commonly used staging system for hepatocellular carcinoma (HCC) helpful with predicting prognosis of advanced HCC. CLIP uses the Child‐Turcotte‐Pugh (CTP) score to evaluate liver reserve. A new scoring system, the albumin–bilirubin (ALBI) grade, has been proposed as they objectively evaluate liver reserve. We examined whether the modification of CLIP with ALBI retained its prognosis prediction for patients with advanced HCC.
Evidence for an Atrial Natriuretic Peptide–-Like Gene in Plants

The presence of a gene found in the animal kingdom expressing a peptide hormonal system in plants has never been demonstrated. However, there is at least one potential hormonal system in plants (i.e., the atrial natriuretic peptide–-like hormonal system) based upon high-performance gel permeation chromatography and radioimmunoassay evidence. In plants, atrial natriuretic–like peptides enhance the flow of water up stems to leaves and flowers. The present investigation was designed to determine within plants the presence of the atrial natriuretic peptide (ANP) gene as defined by Southern blot hydridization, indicating the presence of the ANP gene sequence, and by Northern blots assessing the ability of this gene to express ANP prohormone mRNA. Southern blots of English ivy (Hedra helix) genomic DNA revealed that the ANP gene sequence was present in its roots, stems, and leaves. Northern blot analysis of total plant RNA isolated from leaves, roots, and stems of Hedra helix revealed a single 0.85-kilobase prohormone ANP transcript in stems similar to that detected in rat heart. Semiquantitative analysis suggested that ANP gene expression was less in English ivy compared with that of rat heart atria but similar to the amount found in extra atrial rat tissues when corrected for total RNA when quantitated by 2D scanning. The demonstration of the ANP gene sequences and expression of the ANP-like gene in plants suggests that plants and animals may have evolved much more similarly than previously thought.
Presence of a c-myc transcript initiated in intron 1 in Friend erythroleukemia cells and in other murine cell types with no evidence of c-myc gene rearrangement

In Friend murine erythroleukemia cells, although no detectable c-myc gene rearrangement was found, we observed, in addition to the normal 2.3-kilobase c-myc transcript, the presence of a 2.3-kilobase c-myc mRNA initiated in intron 1 at a promoter site called P3. The intron 1-initiated transcript has a longer half-life than the normal c-myc mRNA. This c-myc transcript initiated in intron 1 was also found in other murine cell types where no rearrangement of the c-myc locus has been reported.
Attrition bias in a U.S. Internet survey of alcohol use among college freshmen.

OBJECTIVE Attrition bias is an important issue in survey research on alcohol, tobacco, and other drug use. The issue is even more salient for Internet studies, because these studies often have higher rates of attrition than face-to-face or telephone surveys, and there is limited research examining the issue in the field of drug usage, specifically for college underclassmen. This study assessed whether measures of high-risk drinking and alcohol-related consequences were related to attrition groups ("stayers" or "leavers") in a cohort of college freshmen. METHOD Data were collected in 2003 and 2004 from 2,144 first-year college students at 10 universities in the southeastern United States. Demographics, indicators of high-risk drinking, and alcohol-related consequences were compared between cohort stayers and leavers in statistical analyses using two methods. RESULTS Analyses indicated that cohort leavers reported significantly higher levels of high-risk drinking (past-30-day heavy episodic drinking, weekly drunkenness) and past-30-day smoking but not significantly increased alcohol-related consequences. The directionality of bias was modestly consistent across outcomes and comparison methods. CONCLUSIONS The current study's findings suggest that intervention efforts to reduce smoking or high-risk drinking need to consider attrition bias during study follow-up or account for it in analyses.
A Comparison of the Generalized minC Combination and the Hybrid DSm Combination Rules

A generalization of the minC combination to DSm hyper-power sets is presented. Both the special formulas for static fusion or dynamic fusion without non-existential constraints and the quite general formulas for dynamic fusion with non-existential constraints are included. Examples of the minC combination on several different hybrid DSm models are presented. A comparison of the generalized minC combination with the hybrid DSm rule is discussed and explained on examples.
Analyse des interactions géopolitiques par la matrice de Google réduite

La geopolitique etudie les relations entre des puissances politiques par rapport a leur situation geographique. Les interactions entre les pays du monde ont ete largement etudiees a differentes echelles, en analysant par exemple des informations issues des echanges economiques, des faits historiques ou l'evolution des reglementations internationales. Cette etude propose d'exploiter les connaissances encyclopediques de Wikipedia pour extraire les interactions entre un ensemble de pays choisis. Wikipedia enregistre ses connaissances sous la forme d'une reseau de pages Internet reliees entre elles par des hyperliens. La structure de ce reseau est porteuse d'informations tres precieuses car elle represente les inter-dependances entre les sujets etudies. Wikipedia est edite en plusieurs langues, la plus volumineuse etant la langue anglaise. L'edition anglaise comporte plusieurs millions de pages et une etude minutieuse des interactions entre certaines pages passe par la definition d'outils mathematiques efficaces et qui capturent les inter-dependances qui existent dans un nombre limite de pages. Dans cet article, nous utilisons la methode d'analyse de la matrice reduite de Google recemment proposee pour extraire les interactions entre 40 pays au niveau mondial. Cette etude est menee pour 5 editions de pages Wikipedia. Cette approche permet d'extraire du reseau, en plus des liens directs, des relations indirectes (ou cachees) entre les 40 pays selectionnes. Ces relations indirectes sont particulierement interessantes car elles ne sont pas influencees par la mesure de PageRank et proposent ainsi un axe d'etude supplementaire pertinent.
Le Visible et l’Invisible

Introduction Nous nous proposons d’etudier ici les relations du poete et critique d’art Marcel Lecomte avec l’invisible. La question que nous nous posons est celle de la place occupee par l’invisible dans ses preoccupations, dont temoigne la critique d’art. Peut-on parler de lui comme d’un souffleur d’indicible ? Acteur du mouvement surrealiste, son portrait, souvent decrit comme une ombre dont on sent la presence en en notant toutefois l’absence, nous revele sa singularite. Singularite qui s.
Facies Architecture and Sequence Stratigraphy of Fine-Grained Lacustrine Deltas Along the Eastern Margin of Late Pleistocene Lake Bonneville, Northern Utah and Southern Idaho

This study documents the effects of changing lake level (limnostasy), tectonics, sediment yield, and basin physiography on the facies architecture, sequence stratigraphy, and reservoir quality of three fine-grained deltas deposited along the eastern margin of late Pleistocene Lake Bonneville. Analysis of facies architecture indicates that the Weber and Spanish Fork deltas were strongly wave-modified because they were situated along openly exposed portions of the shoreline. The Bear River delta, nestled in a relatively isolated northeast arm of the lake, records both fluvial and wave processes. These fine-grained deltas were fed by low-gradient rivers that drained large regions that were sparsely glaciated, whereas other contemporaneous, coarse-grained "Gilbert" deltas were fed by steep-gradient rivers that drained local source areas that were strongly influenced by glaciers. Limnostasy, tectonics, and sediment yield were similar for all three fine-grained deltas, implying that the most influential forcing parameter on sequence stratigraphy is basin physiography. Basin physiography (specifically ramp length and accommodation) most strongly controlled the external and internal geometry of the lowstand systems tract of each delta. Potential hydrocarbon reservoir quality (e.g., grain size and sorting) is largely a product of drainage basin size and stream gradient. Relative differences in ramp lengths seemed to determine thickness and lateral continuity of delta front deposits. Relative differences in accommodation appeared to determine the internal geometry of the delta front deposits, especially in the lowstand systems tract. These deltas can serve as analogs for lacustrine exploration and production where many forcing parameters typically are unknown.
Practices of pediatric oncology and hematology providers regarding fertility issues: A European survey

Fertility is impaired in many survivors of childhood cancer following treatment. Preservation of fertility after cancer has become a central survivorship concern. Nevertheless, several doctors, patients, and families do not discuss fertility and recommendations for fertility preservation in pediatrics are still lacking. Recommendations based on scientific evidence are needed and before their development we wanted to assess the practice patterns of fertility preservation in Europe.
