  El objetivo de esta investigación fue analizar la eficacia de las secuencias de ataque utilizando el cambio de portera - jugadora de campo y sus consecuencias en la siguiente fase defensiva en el balonmano femenino de élite. Se utilizó la metodología observacional. Se empleó un diseño observacional puntual, nomotético y multidimensional. La muestra estuvo compuesta por 571 secuencias de ataque de 50 partidos pertenecientes a la EHF Champions League 2018-2019 de balonmano femenino. Se elaboró un instrumento observacional ad hoc que presenta la combinación de formato de campo y sistemas de categorías. La calidad del dato fue probada mediante concordancia inter e intra observadores. Los resultados destacan que el principal motivo por el cual se hizo uso de la regla que posibilita el cambio portera-jugadora fue mantener la igualdad numérica luego de haber sufrido una sanción disciplinaria, y en menor medida para generar superioridad numérica 7x6. La eficacia presentó los valores más altos cuando se utilizó para generar superioridad numérica. Las situaciones de igualdad numérica 6x6 arrojaron peores valores tanto en eficacia lanzamiento como en pérdidas de pelota. Se concluye que los equipos al atacar con portería vacía asumen un riesgo importante de recibir un gol de forma rápida si el ataque no finaliza en gol, ya que las consecuencias defensivas inmediatas están directamente relacionadas con la eficacia en la fase de ataque.  Abstract. The objective of this research was to analyze the efficacy of the attack sequences performance using the goalkeeper-field player change and its consequences in the following defensive phase in the women´s handball elite. The observational methodology was used. The observational design was punctual, nomothetic and multidimensional.  The sample was 571 attack sequences from 50 matches from EHF Women´s Handball Champion League 2018-2019. An ad hoc observational instrument was developed that presents the combination of field format and category systems. The quality of data was tested by inter and intra observer agreement. The results highlight that the main reason why the rule that makes the goalkeeper-field player change possible was used was to maintain numerical equality after having suffered a disciplinary sanction, and to a less extent to generate 7x6 numerical superiority. The effectiveness presented the highest values when used to generate numerical superiority. The 6x6 numerical equality situations throw worse values in both shooting efficacy and lost balls. It is concluded that the teams assume a significant risk of receiving a goal quickly if the attack does not end in goal, since the immediate defensive consequences are directly related to the effectiveness in the attack phase.

Ampullary lesions (ALs) can be treated by endoscopic (EA) or surgical ampullectomy (SA) or pancreaticoduodenectomy (PD). However, EA carries significant risk of incomplete resection while surgical interventions can lead to substantial morbidity. We performed a systematic review and meta-analysis for R0, adverse-events (AEs) and recurrence between EA, SA and PD. Electronic databases were searched from 1990 to 2018. Outcomes were calculated as pooled means using fixed and random-effects models and the Freeman-Tukey-Double-Arcsine-Proportion-model. We identified 59 independent studies. The pooled R0 rate was 76.6% (71.8–81.4%, I2 = 91.38%) for EA, 96.4% (93.6–99.2%, I2 = 37.8%) for SA and 98.9% (98.0–99.7%, I2 = 0%) for PD. AEs were 24.7% (19.8–29.6%, I2 = 86.4%), 28.3% (19.0–37.7%, I2 = 76.8%) and 44.7% (37.9–51.4%, I2 = 0%), respectively. Recurrences were registered in 13.0% (10.2–15.6%, I2 = 91.3%), 9.4% (4.8–14%, I2 = 57.3%) and 14.2% (9.5–18.9%, I2 = 0%). Differences between proportions were significant in R0 for EA compared to SA (p = 0.007) and PD (p = 0.022). AEs were statistically different only between EA and PD (p = 0.049) and recurrence showed no significance for EA/SA or EA/PD. Our data indicate an increased rate of complete resection in surgical interventions accompanied with a higher risk of complications. However, studies showed various sources of bias, limited quality of data and a significant heterogeneity, particularly in EA studies.

Abstract The main objective of this research was to delve into the concept of playing handball at home from a classical perspective of previous studies. The emergence of regularities or certain patterns of play can be explained by the location of matches. Through an observational methodology and a nomothetic, monitoring and multidimensional design, thirty-nine European elite handball matches were selected (N = 39). A mixed ‘ad hoc’ registration system was designed. Records were made of the last three minutes of home and visiting games of which images were available. Two observers with observational methodology experience participated in the study. The quality of the records was dealt with in an intraobserver and interobserver way. Two different techniques were applied for the treatment of the data: a) detection of behavioral patterns by Theme (p < .005) (Magnusson, 2000) and b) Chaid decision trees (p < .05) using SPSSv.24. The results showed the existence of T-patterns according to the location (different T-patterns: home: 1085; away: 1242) of the matches. The categories most involved in effective launches were unveiled. On the other hand, the Chaid model also showed the effect of location (p < .001): home-win (node 9) (n = 149, 69%), away-win (node 10) (n = 15, 16%) in handball. Crossing analysis offered enriched interpretations to advance in the home advantage concept. From this study, guidelines can be drawn that may help handball coaches to build training tasks as differences in behavioral patterns between home or away play in handball were identified. Thus, designing tasks considering a match location has requires specificity.

En metodología observacional, para abordar la fiabilidad de los datos ya registrados, suele recurrirse a coeficientes de concordancia, coeficientes de correlación o a la teoría de la generalizabilidad; además, cada vez está tomando mayor protagonismo la concordancia consensuada. Esta forma de concordancia trata de lograr la coincidencia entre los observadores antes del registro. A pesar de su creciente presencia en estudios observacionales, son pocos los trabajos que han profundizado en el desarrollo y optimización de esta forma cualitativa de concordancia. El presente trabajo, además de constituirse en un ejemplo de la utilización de la concordancia por consenso, ha comparado el resultado obtenido (tiempo empleado y ajuste con el registro ideal) por grupos de consenso formados por diferente número de integrantes (dos, tres y cuatro observadores). No se han encontrado diferencias significativas al comparar los grupos de concordancia por consenso de dos, tres y cuatro integrantes, ni en relación al tiempo empleado en el registro, ni en lo relativo al porcentaje de acuerdo con el registro ideal. La determinación del tamaño muestral necesario para obtener diferencias significativas entre los grupos, ha permitido elevar conclusiones en términos de eficiencia. The reliability of datasets in observational methodology is typically tested using coefficients of agreement, correlation coefficients, or generalizability theory. Another increasingly popular method used to demonstrate the quality of data is the consensus agreement method, in which two or more observers agree on their coding decisions while creating the dataset. Although the consensus agreement method is being increasingly used in observational studies, few studies have conducted an in-depth analysis of how this qualitative procedure is approached or of how it can be optimized. In this study, in addition to presenting a practical example of the application of the consensus agreement method, we compare the results from three groups (of two, three, and four observers) to analyze performance in terms of time required to code the data and goodness of fit with respect to an optimal dataset. No significant differences were found between the three groups for either of the variables analyzed. Prior calculation of the sample size required to detect significant differences between the groups adds strength to our conclusions regarding the efficiency of the consensus agreement method. Na metodologia observacional, para lidar com a confiabilidade de dois dados já registrados, costumamos passar pelos coeficientes de concordância, coeficientes de correlação ou pela teoria da generalização. Além disso, a concordância consensual vem ganhando cada vez mais destaque. Esta forma de concordância tenta chegar a um acordo entre os observadores antes do registro. Apesar de sua crescente presença em estudos observacionais, poucos estudos se aprofundam no desenvolvimento e otimização de uma forma qualitativa de concordância. Ou apresentar trabalho, além de ser um exemplo do uso de concordância de consenso, comparação ou resultado obtido (tempo despendido e ajuste como registro ideal) por grupos de consenso formados por diferentes números de membros (dois, três e quatro observadores). Não foram encontradas diferenças significativas na comparação de dois grupos de concordância por consenso de dois, três e quatro membros, não em relação ao tempo gasto não registrado, mas em relação ao percentual de concordância conforme lista ideal. A determinação do tamanho dá a amostra necessária para obter diferenças significativas entre os grupos, permitindo-nos tirar conclusões em termos de eficiência.

One goal in electron microscopy of biological specimens is to improve the quality of data to equal the resolution capabilities of modem transmission electron microscopes. Radiation damage and beam- induced movement caused by charging of the sample, low image contrast at high resolution, and sensitivity to external vibration and drift in side entry specimen holders limit the effective resolution one can achieve. Several methods have been developed to address these limitations: cryomethods are widely employed to preserve and stabilize specimens against some of the adverse effects of the vacuum and electron beam irradiation, spot-scan imaging reduces charging and associated beam-induced movement, and energy-filtered imaging removes the “fog” caused by inelastic scattering of electrons which is particularly pronounced in thick specimens.Although most cryoholders can easily achieve a 3.4Å resolution specification, information perpendicular to the goniometer axis may be degraded due to vibration. Absolute drift after mechanical and thermal equilibration as well as drift after movement of a holder may cause loss of resolution in any direction.

Background & Aims: Evaluation of severity and extension of gastric atrophy and intestinal metaplasia is recommended to identify subjects with a high risk for gastric cancer. The inter-observer agreement for the assessment of gastric atrophy is reported to be low. The aim of the study was to evaluate the inter-observer agreement for the assessment of severity and extension of gastric atrophy using oriented and unoriented gastric biopsy samples. Furthermore, the quality of biopsy specimens in oriented and unoriented samples was analyzed.Methods: A total of 35 subjects with dyspeptic symptoms addressed for gastrointestinal endoscopy that agreed to enter the study were prospectively enrolled. The OLGA/OLGIM gastric biopsies protocol was used. From each subject two sets of biopsies were obtained (four from the antrum, two oriented and two unoriented, two from the gastric incisure, one oriented and one unoriented, four from the gastric body, two oriented and two unoriented). The orientation of the biopsy samples was completed using nitrocellulose filters (Endokit®, BioOptica, Milan, Italy). The samples were blindly examined by two experienced pathologists. Inter-observer agreement was evaluated using kappa statistic for inter-rater agreement. The quality of histopathology specimens taking into account the identification of lamina propria was analyzed in oriented vs. unoriented samples. The samples with detectable lamina propria mucosae were defined as good quality specimens. Categorical data was analyzed using chi-square test and a two-sided p value <0.05 was considered statistically significant.Results: A total of 350 biopsy samples were analyzed (175 oriented / 175 unoriented). The kappa index values for oriented/unoriented OLGA 0/I/II/III and IV stages have been 0.62/0.13, 0.70/0.20, 0.61/0.06, 0.62/0.46, and 0.77/0.50, respectively. For OLGIM 0/I/II/III stages the kappa index values for oriented/unoriented samples were 0.83/0.83, 0.88/0.89, 0.70/0.88 and 0.83/1, respectively. No case of OLGIM IV stage was found in the present case series. Good quality histopathology specimens were described in 95.43% of the oriented biopsy samples, and in 89.14% of the unoriented biopsy samples, respectively (p=0.0275).Conclusion: The orientation of gastric biopsies specimens improves the inter-observer agreement for the assessment of gastric atrophy.Key words:  –  –  – .Abbreviations: H. pylori: Helicobacter pylori; OLGA: operative link for gastritis assessment; OLGIM: operative link on intestinal metaplasia assessment.

BACKGROUND Osteoarthritis (OA) is one of the top five most disabling conditions and it affects more than one third of persons over 65 years of age. Currently 80% of persons affected by OA already report having some movement limitation, 20% of people are not be able to perform major activities of daily living, and about 11% of the total affected population need of personal care. On 2014 the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) suggested as first step of pharmacological treatment for knee OA a background therapy with chronic symptomatic slow-acting drugs for osteoarthritis (SYSADOAs), such as glucosamine sulphate, chondroitin sulphate and hyaluronic acid (HA). In studies with oral HA, symptoms of OA are often measured using subjective parameters such as the visual analog scale (VAS) or the quality of life questionnaire (QoL) and objective measurements as ultrasonography (US) or range of motion (ROM) are employed in very few trials. This affects the quality of data in the literature. OBJECTIVE The primary objective of this work is to assess the feasibility of implementing US and ROM as objective measurements to correlate the improvement of knee mobility with pain reduction, evaluated using a subjective scale (VAS) in patients assuming a nutraceutical containing HA. The secondary objective is to evaluate the enrollment rate in one month to verify the feasibility for time and budget of the planned future main study. The explorative objective of the trial is to obtain preliminary data on efficacy of the tested product. METHODS This open-label pilot trial is performed in an orthopedic clinic (Timisoara, Romania). Male and female subjects (from 50 to 70 years) diagnosed with symptomatic OA of the knee with mild joint discomfort for at least 6 months are included. Following protocol, 8 patients are administered for 8 weeks Syalox® 300 Plus (River Pharma, Italy), a product based on HA of high molecular weight. Baseline and final visit assessments include orthopedic assessment, US, Knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire, VAS and ROM of knee. RESULTS Data collection occurred between February 2018 and June 2018. All results are expected to be available by the end of 2018. CONCLUSIONS This pilot trial will be the first study to analyze the potential correlation between subjective evaluation (VAS, KOOS questionnaire) and objective measurements (US, ROM and actigraphy). The data from this study will assess the feasibility of the planned monthly recruitment rate and the necessary time and budget, and should provide preliminary information on efficacy of the tested product.

BACKGROUND There has been an increase number of eHealth and mHealth interventions aimed to support symptoms among cancer survivors. However, patient engagement has not been guaranteed and standardized in these interventions. OBJECTIVE The objective of this review was to address how patient engagement has been defined and measured in eHealth and mHealth interventions designed to improve symptoms and quality of life for cancer patients. METHODS Searches were performed in MEDLINE, PsychINFO, Web of Science, and Google Scholar to identify eHealth and mHealth interventions designed specifically to improve symptom management for cancer patients. Definition and measurement of engagement and engagement related outcomes of each intervention were synthesized. This integrated review was conducted using Critical Interpretive Synthesis to ensure the quality of data synthesis. RESULTS A total of 792 intervention studies were identified through the searches; 10 research papers met the inclusion criteria. Most of them (6/10) were randomized trial, 2 were one group trail, 1 was qualitative design, and 1 paper used mixed method. Majority of identified papers defined patient engagement as the usage of an eHealth and mHealth intervention by using different variables (e.g., usage time, log in times, participation rate). Engagement has also been described as subjective experience about the interaction with the intervention. The measurement of engagement is in accordance with the definition of engagement and can be categorized as objective and subjective measures. Among identified papers, 5 used system usage data, 2 used self-reported questionnaire, 1 used sensor data and 3 used qualitative method. Almost all studies reported engagement at a moment to moment level, but there is a lack of measurement of engagement for the long term. CONCLUSIONS There have been calls to develop standard definition and measurement of patient engagement in eHealth and mHealth interventions. Besides, it is important to provide cancer patients with more tailored and engaging eHealth and mHealth interventions for long term engagement.
