Factors associated with alcohol reduction in harmful and hazardous drinkers following alcohol brief intervention in Scotland: a qualitative enquiry
Background: Alcohol Brief Intervention (ABI) uses a motivational counselling approach to support individuals to
reduce excessive alcohol consumption. There is growing evidence on ABI’s use within various health care settings,
although how they work and which components enhance success is largely unknown. This paper reports on the
qualitative part of a mixed methods study. It explores enablers and barriers associated with alcohol reduction
following an ABI. It focuses on alcohol’s place within participants’ lives and their personal perspectives on reducing
consumption. There are a number of randomised controlled trials in this field though few ABI studies have
addressed the experiences of hazardous/harmful drinkers. This study examines factors associated with alcohol
reduction in harmful/hazardous drinkers following ABI.
Methods: This qualitative study was underpinned by a realist evaluation approach and involved semistructured
interviews with ten harmful or hazardous alcohol drinkers. Participants (n = 10) were from the
intervention arm of a randomised controlled trial (n = 124). All had received ABI, a 20 min motivational
counselling interview, six months previously, and had reduced their alcohol consumption. Interviews were
recorded, transcribed verbatim and thematically analysed.
Results: Participants described their views on alcohol, its’ place in their lives, their personal perspectives on
reducing their consumption and future aspirations.
Conclusions: The findings provide an insight into participants’ views on alcohol, ABI, and the barriers and enablers
to change. Participants described a cost benefit analysis, with some conscious consideration of the advantages and
disadvantages of reducing intake or abstaining from alcohol. Findings suggest that, whilst hospital admission can act
as a catalyst, encouraging individuals to reflect on their alcohol consumption through ABI may consolidate this, turning
this reflective moment into action. Sustainability may be enhanced by the presence of a ‘significant other’ who
encourages and experiences benefit. In addition having a purpose or structure with activities linked to employment
and/or social and leisure pursuits offers the potential to enhance and sustain reduced alcohol consumption.

Biomechanical considerations in the pathogenesis of osteoarthritis of the knee
Osteoarthritis is the most common joint disease and a major cause of disability. The knee is the large joint most affected. While chronological age is the single most important risk factor of osteoarthritis, the pathogenesis of knee osteoarthritis in the young patient is predominantly related to an unfavorable biomechanical environment at the joint. This results in mechanical demand that exceeds the ability of a joint to repair and maintain itself, predisposing the articular cartilage to premature degeneration. This review examines the available basic science, preclinical and clinical evidence regarding several such unfavorable biomechanical conditions about the knee: malalignment, loss of meniscal tissue, cartilage defects and joint instability or laxity
An evaluation of long-term changes in alcohol use and alcohol problems among clients of the Swedish National Alcohol Helpline
Large expert-curated database for benchmarking document similarity detection in biomedical literature search
Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency–Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research

Changes in biomechanical risk factors for knee osteoarthritis and their association with 5-year clinically important improvement after limb realignment surgery
Objective: To evaluate 5-year outcomes after lower limb realignment and test the hypothesis that surgery-induced changes in selected biomechanical risk factors for medial knee osteoarthritis (OA) are associated with clinically important improvements. Design: We prospectively evaluated patient-reported outcomes, full-limb standing radiographs and gait biomechanics before, 6 months (surgery-induced change) and 5 years after medial opening wedge high tibial osteotomy (HTO) in 170 patients (46.4 +/- 8.9 years, 135 males) with knee OA and varus alignment. Logistic regression tested the associations of 6-month changes in mechanical axis angle and knee adduction moment with achieving an increase of \u3e= 10 points in the Knee injury and Osteoarthritis Outcome Score (KOOS) 4 at 5 years, with and without adjusting for covariates. Gait data were also compared to existing data from healthy controls. Results: Mean 5-year changes (95% confidence interval (CI)) were: KOOS4: +14.2 (10.8, 17.6); mechanical axis angle: +8.21 degrees (7.58, 8.83); knee adduction moment: -1.49 % BW*Ht (-1.35, -1.63). The postoperative knee adduction moments were typically lower than values for healthy controls. When divided into quartiles, although all strata improved significantly, patients with reductions in knee adduction moment of 1.14-1.74 % BW*Ht (neither largest nor smallest changes) had highest 5-year KOOS4 scores. The 6-month change in knee adduction moment (odds ratios (OR) = 0.38; 95% CI: 0.22, 0.67), preoperative KOOS4(OR = 0.96; 95% CI: 0.94, 0.99) and preoperative medial tibiofemoral narrowing grade (OR = 0.62; 95% CI: 0.37, 1.00) were negatively associated with having a 5-year clinically important improvement (C-statistic = 0.70). Conclusions: Substantial improvements in biomechanical risk factors and patient-reported outcomes are observed 5 years after medial opening wedge HTO. The surgery-induced change in load distribution during walking is significantly associated with long-term clinically important improvement. (C) 2017 Osteoarthritis Research Society International.
