The Impact of Depression on Patient Outcomes in Hip Arthroscopic Surgery.

Background: Mental health impairments have been shown to negatively affect preoperative self-reported function in patients with various musculoskeletal disorders, including those with femoroacetabular impingement. Hypothesis: Those with symptoms of depression will have lower self-reported function, more pain, and less satisfaction on initial assessment and at 2-year follow-up than those without symptoms of depression. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who were enrolled in a multicenter hip arthroscopic surgery registry and had 2-year outcome data available were included in the study. Patients completed the 12-item International Hip Outcome Tool (iHOT-12), visual analog scale (VAS) for pain, and 12-item Short-Form Health Survey (SF-12) when consenting for surgery. At 2-year follow-up, patients were emailed the iHOT, the VAS, and a rating scale of surgical satisfaction. Initial SF-12 mental component summary (MCS) scores Results: A total of 781 patients achieved the approximate 2-year milestone (mean follow-up, 735 ± 68 days), with 651 (83%) having 2-year outcome data available. There were 434 (67%) female and 217 (33%) male patients, with a mean age of 35.8 ± 13.0 years and a mean body mass index of 25.4 ± 8.8 kg/m Conclusion: A large number of patients who underwent hip arthroscopic surgery presented with symptoms of depression, which negatively affected self-reported function, pain levels, and satisfaction on initial assessment and at 2-year follow-up. Surgeons who perform hip arthroscopic surgery may need to identify the symptoms of depression and be aware of the impact that depression can have on surgical outcomes

The Emerging Internet of Things Marketplace From an Industrial Perspective: A Survey

The Internet of Things (IoT) is a dynamic global information network consisting of internet-connected objects, such as Radio-frequency identification (RFIDs), sensors, actuators, as well as other instruments and smart appliances that are becoming an integral component of the future internet. Over the last decade, we have seen a large number of the IoT solutions developed by start-ups, small and medium enterprises, large corporations, academic research institutes (such as universities), and private and public research organisations making their way into the market. In this paper, we survey over one hundred IoT smart solutions in the marketplace and examine them closely in order to identify the technologies used, functionalities, and applications. More importantly, we identify the trends, opportunities and open challenges in the industry-based the IoT solutions. Based on the application domain, we classify and discuss these solutions under five different categories: smart wearable, smart home, smart, city, smart environment, and smart enterprise. This survey is intended to serve as a guideline and conceptual framework for future research in the IoT and to motivate and inspire further developments. It also provides a systematic exploration of existing research and suggests a number of potentially significant research directions.Comment: IEEE Transactions on Emerging Topics in Computing 201

A review of teacher evaluation beliefs

Teacher evaluation beliefs have received a substantial amount of attention in the educational literature, but comparatively little attention from the belief research topics specially. As the driving force, evaluation resembles belief mention but lack the systemic description. On the base of the student-centered and teacher-centered philosophy, in the present paper, we provide a literature review to explore the essential factors of teacher evaluation beliefs (why, what, who, when and how), followed by the key problems of Chinese New Curriculum Reform as “why-aim”, “what-content”, “who-student-teacher relationship”, “how-method” and “when- time”. In line with the discussion of five factors of evaluation beliefs, we proposed six perspectives to inform educational researchers for the further researches

Ideation as an intellectual information acquisition and use context: Investigating game designers’ information-based ideation behavior

Human Information Behavior (HIB) research commonly examines behavior in the context of why information is acquired and how it will be used, but usually at the level of the work or everyday-life tasks the information will support. HIB has not been examined in detail at the broader contextual level of intellectual purpose (i.e. the higher-order conceptual tasks the information was acquired to support). Examination at this level can enhance holistic understanding of HIB as a ‘means to an intellectual end’ and inform the design of digital information environments that support information interaction for specific intellectual purposes. We investigate information-based ideation (IBI) as a specific intellectual information acquisition and use context by conducting Critical Incident-style interviews with ten game designers, focusing on how they interact with information to generate and develop creative design ideas. Our findings give rise to a framework of their ideation-focused HIB, which systems designers can leverage to reason about how best to support certain behaviors to drive design ideation. These findings emphasize the importance of intellectual purpose as a driver for acquisition and desired outcome of use

Addressing Obesity in Stevenage, Hertfordshire: A Consultation with Young People

Public Health England have identified that almost a quarter of children are overweight when they start primary school, which increases to a third when they leave in year 6 aged 10-11 years. This has implications for young peoples’ physical and mental health and also later in adult life. The newly launched NIHR Applied Research Collaboration (ARC) East of England is focusing on selected areas of health inequality and this includes neighbourhoods in Stevenage, Hertfordshire which have high rates of childhood obesity. In order to find out what young people think about these issues, Hertfordshire County Council and the University of Hertfordshire carried out a collaborative project in 2019. Hertfordshire County Council have adopted a Whole Systems approach to obesity and are keen to engage with young people in order to prioritise issues identified by them. The importance of ‘involving’ young people in shaping services has been widely documented. Two researchers met twice with 56 young people (from a range of schools) aged 16 years who were attending the National Citizen Service (NCS) scheme at a school in Stevenage in the summer holidays. A number of involvement activities were carried out during the sessions. The young people, with help from the researchers, facilitated their own informal discussion groups, using maps, flips charts, post-it notes and an anonymous suggestion box. The first session did not mention obesity but allowed open discussion about what it was like to live in Stevenage and the second session focussed more on the issue of ‘obesity and weight’. The young people were encouraged to find their own solutions and imagine if they “were in charge”. The four main themes that came from the sessions were; affordability, crime and anti-social behaviour, transport and places to go and eat. A number of solutions were suggested by the young people which included; healthy environment (e.g. cycle paths, street lights, regulation of shops), community approach (e.g. more affordable sports activities), schools (e.g. raise awareness, promote sport), focus on young people (e.g. activities for young people and healthy affordable eating outlets) and helping people maintain a healthy weight. The priorities identified by local young people and the wider issues they raised are important to take into consideration when shaping any intervention or public health initiative, especially when considering the wider determinants of health. Listening to the issues and solutions and using the language of young people is vital and young people should be included in co-designing any services that are aimed at them. Involving local young people who know an area and who can identify important issues is vital for any successful public health intervention

A case study of technical change and rehabilitation: Intervention design and interdisciplinary team interaction

The design of effective interventions in sport psychology often requires a subtle blend of techniques, tailored to meet the client’s specific needs. Input from a variety of disciplinary support specialists, working as a team, is also frequently needed. Accordingly, this study investigated an interdisciplinary team approach to the technical change and rehabilitation of an elite weight lifter following injury; necessitating the avoidance of regression when performing under competitive pressure. Multiple coaching approaches were used and complimented by targeting specific mental skills. Kinematic analyses indicated progressive technical, and subsequently permanent, change even after 2 years. Self-report measures of self-efficacy and imagery use were deemed essential in facilitating the change. Finally, a discussion focuses on the intervention’s multifactorial nature, its application within high performance coaching, and how this may advise future research into the refinement of already existing and well-established skills
