Serve profile of male and female professional tennis players at the 2015 Roland Garros Grand Slam tournament

The aim of this study was to compare the serve statistics profile of male and female high-level tennis players. In all, 111 tennis singles matches of the Roland Garros 2015 tennis tournament were collected and 10 variables related to first and second serve were analyzed according to service box (deuce and advantage sides) and landing location (wide, body and T-areas). The results show: (a) men served faster than women; (b) men served a higher percentage of serves at T-area on deuce side (35.0 vs 27.7%) and at the wide zone on advantage side (44.1 vs 36.7%) with first serves, while women hit more to the body on both sides; (c) men won a higher percentage of points with their first serve compared to women at any zone on both sides, except for the T-area on deuce side; (d) with their second serve, men placed a greater percentage of serves in the T-area on deuce side (28.0 vs 21.8%) and wide on the advantage side, whereas women directed more to the body on the advantage side (41.4 vs 33.5%); (e) men won a higher percentage of points with their second serve when they placed it to the body zone on deuce side (54.1 vs 47.1%) and at the T-area on the advantage side (64.4% vs 44.1%). Our conclusions are that with respect to gender, players showed differing serve patterns. Men served faster, with higher success and placed their serves more frequently to the external areas of the service boxes, while women directed a higher percentage of serves to the body of their opponent

Statistical Differences in Set Analysis in Badminton at the RIO 2016 Olympic Games

The aim of the present study was to determine statistical differences in a set of badminton competition matches in five different modalities with regard to competition level (Group Phase vs. Eliminatory Phase). Data from 453 sets (125 in men's singles; 108 sets in women's singles; 77 sets in men's doubles; 73 in women's doubles and 70 in mixed doubles) from the RIO 2016 Olympics Games were recorded and classified in two groups of variables to analyze variables related to match (5) and set (15). A descriptive analysis and univariate test (Mann-Whitney U) for non-parametric data were conducted. The results show in men's and women's singles all the variables related to match were higher in the Elimination Phase than in the Group Phase (p < 0.01). In Sets 1 and 3, the longest set duration, rally and average rally were found in the Elimination Phase than Group Stage (p < 0.05). In women's singles, these differences were also recorded in Set 2. For doubles, the results are more stable among groups. Men's doubles had a longer duration of the match and set (sets 1 and set 2) (p < 0.01), and also scored highest for average rally strokes (sets 1 3) < 0.05) and shuttles used in the Elimination Phase vs. the Group Phase along the match (p < 0.01). In women's doubles, more shuttles were used in a match in the Elimination than in the Group Phase. Moreover, the same results are established for Set 2, including for average rally. Mixed doubles saw no match going to three sets. However, the greatest differences showed a longer rally and average rally being registered in the Elimination than in the Group Phase. In conclusion, the timing factors of the badminton singles and doubles games were different in the Elimination and Group Phases. This information may help players and coaches prepare and administer different types of workouts or, more specifically, competition schedules adapted to the characteristics of modern badminton

Segurança do paciente no centro cirúrgico e qualidade documental relacionadas à infecção cirúrgica e à hospitalização

Objective: To describe the documentary quality of two records related to patient safety in the operating room and to identify differences between information related to infection and hospitalization. Methods: Comparative study based on two cross sections, conducted with 3,033 patients who had been hospitalized for more than 24 hours in an Orthopedics and Traumatology Center. Sociodemographic and clinical data, as well as information provided in forms were compared. Postoperative infection was identified as an adverse event. Results: There was a significant correlation between hospitalization days and the total number of diagnoses collected (Pearson=0.328; p<0.001). When diagnoses and infections were grouped together, a significant value was found between closed fractures and infection (p=0.001). Conclusion: Differences in the degree of completion were observed between the two records. There were no differences between adverse events.Objetivo: Descrever a qualidade documental de dois registros relacionados à segurança de pacientes no centro cirúrgico e estabelecer as diferenças nas informações relacionadas à infecção cirúrgica e à permanencia hospitalar. Métodos: Estudo comparativo baseado em dois cortes transversais, realizado com 3.033 pacientes internados há mais de 24 horas, advindos de Cirurgia Ortopédica e Traumatologia. Foram comparados dados sociodemográficos, clínicos e de preenchimento. Mediu-se a infecção pós-cirúrgica como um efeito adverso. Resultados: Houve correlação significativa entre os dias de hospitalização e o número total de diagnósticos coletados (Pearson=0,328; p<0,001). Quando se agruparam os diagnósticos e a infecção, notou-se um valor significativo entre as fraturas fechadas e a infecção (p=0,001). Conclusão: Foram observadas diferenças no grau de preenchimento entre os dois registros. Não houveram diferenças no evento adverso

Surgical safety and filling-in of the records about intraoperative information in Spain: A comparative analysis of two recording instruments

El objetivo del presente estudio es describir y comparar los porcentajes de no cumplimentación de dos instrumentos de registro: hoja circulante (HC) y lista de verificación quirúrgica (LVQ), en un mismo entorno quirúrgico para una muestra de pacientes de características similares. Metodología: Estudio descriptivo realizado sobre registros intraquirúrgicos de 3024 pacientes de Cirugía de Ortopedia y Traumatología. 1732 pacientes intervenidos en 2009 con modelo de hoja circulante, cumplimentada al finalizar la intervención y 1292 en 2010 intervenidos con modelo de registro lista de verificación quirúrgica (checklist) cumplimentado durante la intervención en tres tiempos. Se han calculado características descriptivas (media, desviación típica, mínimo y máximo) del porcentaje de no cumplimentación global en ambos registros y el porcentaje de no cumplimentación (intervalo de confianza al 95%) de cada ítem de los registros estudiados. Resultados: Se observa mayor porcentaje de cumplimentación global y, en general, también individual, en la hoja circulante que en la lista de verificación quirúrgica. Conclusiones: El registro intraquirúrgico que mayor porcentaje de cumplimentación ha tenido de manera global ha sido la hoja de circulante y se evidencia la necesidad de implantar estrategias para mejorar el grado de cumplimentación de la LVQ por su relación con la seguridad de pacientes.The objective of this study is to describe and compare the percentages of non-filling-in two recording instruments: Current sheet and surgical checklist in the same surgical setting for a sample of patients with similar characteristics. Methods: Descriptive study carried out with the intraoperative records of 3024 patients from Orthopedic Surgery and 1732 patients who were operated in 2009 with current sheet model completed at the end of the surgery and 1292 patients in 2010 with surgical checklist as recording model, completed during the intervention in three stages. Descriptive characteristics (mean, standard deviation, minimum and maximum) were calculated from the overall percentage of non-completion in both records, as well as the non-filling-in percentage (and confidence interval at 95%) of each item of the records studied. Results: A higher overall – and also individual, in general- percentage of filling-in is observed in the current sheet than in the surgical checklist. Conclusions: In general terms, the intraoperative recording with the highest percentage of being filled-in has been the circulating sheet and it has been observed the necessity to implement strategies to improve the level of filling-in due to its relationship with surgical clinical safety

Characteristics of Nursing Interventions That Improve the Quality of Life of People With Chronic Diseases. A Systematic Review With Meta-Analysis

Purpose The objective of this systematic review was to determine the characteristics of the interventions conducted by nurses that attempt to improve the health related quality of life (HRQoL) of people over 18 years of age with chronic diseases. Methods This systematic review with meta-analysis summarizes 24 studies, conducted in 10 countries, that evaluated HRQoL through the Short-Form Health Survey (SF). Five databases were accessed to find the available studies from December 31st, 2000 to May 22sd, 2017. Selected studies were coded according to the characteristics of the sample and the intervention. A model of random effects was adopted for the overall estimation and to explain the heterogeneity. Results Twenty-four studies were included in the systematic review and meta-analysis providing a sample of 4324 chronic patients aged 63.4 years. Among the 8 subscales and two summary measures that comprise the SF-36, only an overall significant effect size (ES) index was found in the Mental Health Component summary score (ES = 0.14; 95% CI:0.03 ? 0.26; I2 = 44.6, p = 0.042) and the Mental Health subscale. This improvement on HRQoL was associated to interventions on ?Case Management? and ?Treatments and Procedures?, which were based on a theory, were of shorter duration, and had a follow-up period. Conclusions Interventions targeting people with chronic diseases resulted in a slight increase in the HRQoL that was not always significant, which suggests that there is a need for their continuous improvement.Funding: This project was funded by the University of Cantabria (Spain).

Why are spanish nurses going to work sick? questionnaire for the measurement of presenteeism in nurses

Presenteeism is defined as the presence of the worker at their workplace despite not being in optimal physical or mental conditions. Presenteeism is a phenomenon that has been poorly studied in the context of healthcare. Despite the many negative consequences associated with presenteeism, to date, no studies have investigated this issue in nurses in Spain. The objective was to develop and validate a questionnaire on presenteeism to be used by nursing staff in Spain. Methods: A psychometric study for the development and validation of a questionnaire. The PRESENCA® questionnaire on presenteeism was created by a panel of experts, based on a survey comprised of 31 Likert-type items. Results: In total, 355 nurses completed the questionnaire. The factorial analysis revealed the existence of 3 factors and confirmed appropriate levels of validity and reliability (alpha = 0.729). Conclusions: The PRESENCA® questionnaire is the first tool developed and validated in Spanish for the assessment of presenteeism in nursing. Our findings demonstrate that this scale has appropriate psychometric properties and its use may facilitate the detection of presenteeism among professionals. As a result, use of this questionnaire may contribute towards the improvement of clinical safety

The musicality of C-pop : a study of Chinese popular music from 1985-2010.

This study examines C-pop (Chinese pop). It contains three parts, Part One describes the changes in C-pop from the 1985 to the present, Part Two deals with how C-pop changed in terms of its musical texts and Part Three elucidates why it changed culturally. As a whole, it also provides a case study that allows us to approach the 'popular'I'pop' dichotomy from perspective of a change in musicality (way of being musical) from a music-maker-centric (MMC) system to a music-receiver-centric (MRC) system. I have drawn on the dual experience base of being a native Chinese and an overseas-based researcher, generating a critical-ethnomusicological perspective throughout. Part One of the thesis considers a selection of soundscapes that delineate changing trends in Chinese popular music from 1985 on. In the first chapter, the emergence of C-pop in the 1980s and early 1990s is identified and assessed. Chapter 2 looks at the reshaping of the industry from 1996 on, analysing also the rise of new media for popular music during this period, most obviously television and the internet. Part Two looks in more depth at the linguistic (Chapter 3) and vocal (Chapter 4) codes embedded in the music. The writing here focuses on the relationship between producers and receivers of C-pop and between the music itself and receivers. Chapter 5 underlines this latter emphasis by critically reflecting on the ways in which songs are structured and produced. Finally, Part Three employs a tripartite model of music, music-maker and music-receiver to attend in tum to fan culture (Chapter 6), the roles of musicians (Chapter 7) and the operation of producers and managers in the music industry (Chapter 8). These analyses show why C-pop has developed in the ways in which it has, the ongoing power struggle between the audience and musician-between those holding a mass concept and those holding an elite concept- determining the musicality of C-pop in present-day mainland China
