Golfers are physically more active and have greater health associated quality of life than non-golfers following lower limb arthroplasty.

Background: The health benefits of physical activity are well recognised. This study assessed whether golfers were more physically active after lower limb arthroplasty when compared to those that did not play golf (primary outcome). In addition pre and postoperative changes in health-associated quality of life (HAQoL) and joint specific outcomes between golfers and none golfers were assessed (secondary outcomes). Methods: There were 304 patients [THA (n = 155) or TKA (n = 149)] prospectively registered during a 4-month period undergoing lower limb arthroplasty. The mean age was 70.0 (range 37-92, standard deviation 10.2) years and included 188 (61%) females and 120 (39%) males. They completed pre and postoperative questionnaires assessing recreational activity, physical activity, HAQoL (EuroQol [EQ]), joint specific health (Oxford scores), and satisfaction. Results: Golfers (n = 33, 10.9%) were more likely to achieve longer than 3 hours of moderate activity during a week (48.5% vs 38.0%, odds ratio (OR) 3.4, p = 0.045) and achieved their recommended activity level (96.8% vs 77.7%, OR 8.6, p = 0.015) compared to non-golfers following arthroplasty. Postoperative EQ5D (p = 0.034) and EQVAS (p = 0.019) were significantly greater in golfers. The joint specific Oxford hip score was greater in golfers compared to non-golfers (mean difference 5.6, p = 0.022), however no difference was observed in the Oxford knee score following TKA (p = 0.495). Conclusion: Golfers were more likely to achieve their weekly recommended level of physical activity and had a greater HAQoL relative to those that did not play golf following lower limb arthroplasty. More specifically after THA golfers also had a greater postoperative joint specific outcome, but no such advantage was observed in those following TKA. Evidence Level: Level II, diagnostic study.

Trends in incidence and average waiting time for arthroplasty from 1998-2021: an observational study of 282,367 patients from the Scottish arthroplasty project.

BACKGROUND: Current waiting times for arthroplasty are reported as being the worst on record. This is a combination of increasing demand, the COVID-19 pandemic and longer standing shortage of capacity. The Scottish Arthroplasty Project (SAP) is a National Audit that analyses all joint replacements undertaken in the Scottish NHS and Independent Sector. The aim of this study was to investigate the long-term trend in provision and waiting time for lower limb joint replacement surgery. METHODS: All total hip replacements (THR) and total knee replacements (TKR) undertaken in NHS Scotland from 1998 to 2021 were identified. Waiting times data were analysed each year to determine the minimum, maximum, median, mean and standard deviation. RESULTS: In 1998, there were 4,224 THR and 2,898 TKR with mean (range, SD) waiting time of 159.5 days (1-1,685, 119.8) and 182.9 days (1-1,946, 130.1). The minimum waiting times were both in 2013 for 7,612 THR - 78.8 days (0-539, 46) and 7,146 TKR - 79.1 days (0-489, 43.7). The maximum waiting times recorded were in 2021 with 4,070 THR waiting 283.7 days (0-945, 215) and 3,153 TKR waiting 316.8 days (4-1,064, 217). CONCLUSIONS: This is the first robust large-scale national dataset showing trends in incidence and waiting time for THR and TKR over two decades. There was an expansion of activity with a reduction in waiting time, which peaked in 2013, followed by an increase in waiting time with a plateau and modest decline in the number of procedures.

Condition of surplus dairy calves during marketing: A cross-sectional study.

In North America, surplus dairy calves are sold soon after birth and often marketed through a third party (e.g., live auction, livestock dealer) before entering veal or dairy beef production. Previous work has demonstrated that a percentage of calves have failed transfer of passive immunity (FTPI) and clinical signs of disease on arrival at calf-raising facilities, but little is known regarding calf condition during marketing. The objectives of this cross-sectional study were to (1) estimate the prevalence of FTPI and poor health outcomes in surplus calves on arrival at livestock dealers, and (2) investigate the association between calf-level variables (body weight, sex, source) and health outcomes. Two livestock dealers in Ohio were visited 2 to 3 times per week, with approximately 28 calves enrolled in the study per visit for a total of 1,119 calves. One blood sample per calf was obtained to evaluate FTPI by measuring serum total protein concentrations (using a cutoff <5.1 g/dL). Calves were clinically evaluated for signs of arthritis, broken ribs or tail, dehydration, depression, diarrhea, fever, navel inflammation, and respiratory disease by 2 observers; health outcomes were dichotomized using clinically relevant cut points. Descriptive statistics were used to estimate the prevalence of calves with poor health outcomes. Multivariable logistic regression models were built to investigate the effect of body weight, sex, and source on health outcomes. Nineteen percent (206/1091) of calves had FTPI. Calves purchased from a third party were less likely to have FTPI compared with those purchased directly from the dairy farm (OR: 0.5; 95% CI: 0.3 to 0.8). Upon clinical examination, 69.2% (769/1112) of calves were considered dehydrated, 26.3% (293/1112) had navel inflammation, and 7.3% (82/1118) were depressed. Males were more likely than females to have navel inflammation (OR: 1.8; 95% CI: 1.2 to 2.7). This research highlights the opportunity for continued improvements in surplus calf care, including colostrum management, for female and male dairy calves. Strategies to mitigate dehydration and navel inflammation are also encouraged before calves enter veal or dairy beef production.

Presence of flavoured electronic nicotine delivery system (ENDS) products in US ENDS advertisements, 2015-2020: a content analysis.

OBJECTIVES: Electronic nicotine delivery systems (ENDS) products come in a variety of flavours (eg, fruit, dessert, menthol). Tobacco advertising has historically used flavours as an advertising tactic, but little is known about flavour type and prevalence in ENDS advertisements. We assess the presence of flavoured ENDS in ads over time, by media outlet (eg, magazines, online) and brand. METHODS: We acquired ENDS ads (N=4546) that first ran between 2015-2017 (n=1685; study 1) and 2018-2020 (n=2861; study 2) in outlets including opt-in emails, direct-to-consumer mail (study 1 only), video (TV and online), radio (study 2 only), static online/mobile (ie, ads without video or moving graphics), social media, outdoor (eg, billboards; study 2 only) and consumer magazines. We coded for presence of flavoured ENDS products and flavour type (eg, fruit, tobacco, menthol) and merged this information with metadata on ad year, outlet and manufacturer/retailer brand. RESULTS: Overall, nearly half (45.5%; n=2067) of ads in our sample featured a flavoured product. Tobacco (59.1%; n=1221), menthol (42.9%; n=887) and fruit (38.6%; n=797) were the most advertised flavours. Over time, the proportion of ads containing tobacco-flavoured and menthol-flavoured ENDS generally decreased before menthol rebounded in 2020. The proportion of ads containing fruit, mint and dessert flavours generally increased over time, with a substantive drop in 2020. We found notable differences in flavoured ENDS advertising by outlet and brand. CONCLUSIONS: The overall presence of flavoured ENDS in our sample of ads remained relatively consistent, with tobacco flavour decreasing over time and some non-tobacco flavours increasing over time until 2020 when the presence decreased.

The Right to Sexuality, Reproductive Health, and Found a Family for People with Intellectual Disability: A Systematic Review.

Although sexuality, reproductive health, and starting a family are human rights that should be guaranteed for all citizens, they are still taboo issues for people with intellectual disability (ID), and even more so for women with ID. This paper systematically reviews the current qualitative and quantitative evidence on the rights of people with ID in regard to Articles 23 (right to home and family) and 25 (health, specifically sexual and reproductive health) of the Convention on the Rights of Persons with Disabilities (CRPD). A systematic review of the current literature, following PRISMA 2020, was carried out in ERIC, PsychInfo, Scopus, PubMed, ProQuest, and Web of Science. In all, 151 articles were included for review. The studies were categorized into six themes: attitudes, intimate relationships, sexual and reproductive health, sexuality and sex education, pregnancy, and parenthood. There are still many barriers that prevent people with ID from fully exercising their right to sexuality, reproductive health, and parenthood, most notably communicative and attitudinal barriers. These findings underline the need to continue advancing the rights of people with ID, relying on Schalock and Verdurgo's eight-dimensional quality of life model as the ideal conceptual framework for translating such abstract concepts into practice and policy.

Super Liquid-repellent Surfaces and 3D Spheroids Growth.

Substrates composition and surface features of materials rule adhesion control of cells to surfaces. As a result, most of the aspects of cell functions, such as spreading, migration, proliferation, and differentiation, can be significantly influenced in biomedical applications. Cell cultures make possible to understand cell biology, tissue morphology, mechanisms of diseases, drug action, and tissue engineering development, among others. Recent techniques related to culturing 3D cell aggregates in the presence of very low wettable surfaces represent an innovative field for in vitro experimentation aimed at more reliable conditions to investigate both tumor and non-tumor cell lines. Matching in particular cell biology to innovative materials, this work reviews the recent literature available on promoting cell aggregates formation strongly influenced by the high surface hydrophobicity. In particular, for spheroid formation, the highest water repellent coatings seem to be required for the significant effectiveness of the process. In this way, 3D cell culture has become a reliable method for reproducing in vitro cellular growth in more realistic physiological conditions.

Quality of Life and the International Convention on the Rights of Persons With Disabilities: Consensus Indicators for Assessment.

BACKGROUND: The quality of life construct provides an ideal conceptual framework for translating such abstract concepts as self-determination, equity, accessibility, and inclusion. Through consultation with expert raters, we sought to develop and validate a bank of indicators and items, based on the quality of life conceptual framework, to be used as a means of evaluating and implementing the Articles of the Convention on the Rights of Persons with Disabilities (CRPD). METHOD: Thirty-two experts in the field of intellectual and developmental disabilities participated, rating the suitability, importance, and clarity of a bank of 296 items, as well as the relevance of controlling for 70 sociodemographic variables. RESULTS: After qualitative and quantitative analysis of the data, the final selection comprised 60 sociodemographic variables and 153 items that scored highly on all criteria and produced an excellent level of agreement between the experts. CONCLUSIONS: This bank of items and set of sociodemographic variables constitute the pilot version of a CRPD assessment and monitoring instrument with sufficient evidence of content validity, which may be useful in developing evidence-based practices and in detecting rights violations.

Mammalian Cell Spheroids on Mixed Organic-Inorganic Superhydrophobic Coating.

Three-dimensional cell culture has become a reliable method for reproducing in vitro cellular growth in more realistic physiological conditions. The surface hydrophobicity strongly influences the promotion of cell aggregate formation. In particular, for spheroid formation, highly water-repellent coatings seem to be required for the significant effects of the process. In this work, surfaces at different wettability have been compared to observe their influence on the growth and promotion of aggregates of representative mammalian cell lines, both tumoral and non-tumoral (3T3, HaCat and MCF-7 cell lines). The effect of increased hydrophobicity from TCPS to agarose hydrogel to mixed organic-inorganic superhydrophobic (SH) coating has been investigated by optical and fluorescence microscopy, and by 3D confocal profilometry, in a time scale of 24 h. The results show the role of less wettable substrates in inducing the formation of spheroid-like cell aggregates at a higher degree of sphericity for the studied cell lines.

Prospective epidemiological study of basketball injuries during one competitive season in professional and amateur Spanish basketball.

INTRODUCTION: There are few Spanish epidemiological studies of basketball injuries, even though it is the second most played sport and the leading sport played by females in Spain. POPULATION: We studied 117 male and female basketball players from ten amateur or professional teams from four leagues in the 2014-2015 season. RESULTS: There were 11.6 injuries per 1,000 hours of sporting activity, 9.6 injuries per 1,000 hours of training and 47.3 injuries per 1,000 hours of competition. The rate of injuries requiring downtime was 2.99 per 1,000 hours of training, 41.7 per 1,000 hours of competition and 4.1 per 1,000 hours of sporting activity overall. No significant differences were found in the incidence of injuries between leagues, but a higher incidence by season was found in teams participating in international competitions, due to the increased competition time. The ankle was the main site of injuries causing ≥ 8 days of downtime and knee injuries the site of those causing ≥ 29 days of downtime. The most frequent injuries were sprains, bruises, and muscle overloads and 63.8% of players had ≥ 1 potentially-recurring injury. The most prevalent injuries were ankle sprains (50%), thigh muscle injuries (12.2%) and knee tendinitis (7.4%). The only significant predisposing factor for injury was recurrent injury (adjusted OR 1.93, 95% CI 1.029-3.62). Age, sex, height, weight, position, body mass index, and professional/amateur competition were not significantly associated with the number of injuries or ≥ 7 days downtime in the multivariate analysis. CONCLUSION: Preventive measures should be applied to the team as a whole at an early age, since recurrent injuries only explained a small percentage of the total injuries.

Aggregation Behavior, Antibacterial Activity and Biocompatibility of Catanionic Assemblies Based on Amino Acid-Derived Surfactants.

The surface activity, aggregates morphology, size and charge characteristics of binary catanionic mixtures containing a cationic amino acid-derived surfactant N(π), N(τ)-bis(methyl)-L-Histidine tetradecyl amide (DMHNHC14) and an anionic surfactant (the lysine-based surfactant Nα-lauroyl-Nεacetyl lysine (C12C3L) or sodium myristate) were investigated for the first time. The cationic surfactant has an acid proton which shows a strong pKa shift irrespective of aggregation. The resulting catanionic mixtures exhibited high surface activity and low critical aggregation concentration as compared with the pure constituents. Catanionic vesicles based on DMHNHC14/sodium myristate showed a monodisperse population of medium-size aggregates and good storage stability. According to Small-Angle X-Ray Scattering (SAXS), the characteristics of the bilayers did not depend strongly on the system composition for the positively charged vesicles. Negatively charged vesicles (cationic surfactant:myristate ratio below 1:2) had similar bilayer composition but tended to aggregate. The DMHNHC14-rich vesicles exhibited good antibacterial activity against Gram-positive bacteria and their bactericidal effectivity declined with the decrease of the cationic surfactant content in the mixtures. The hemolytic activity and cytotoxicity of these catanionic formulations against non-tumoral (3T3, HaCaT) and tumoral (HeLa, A431) cell lines also improved by increasing the ratio of cationic surfactant in the mixture. These results indicate that the biological activity of these systems is mainly governed by the cationic charge density, which can be modulated by changing the cationic/anionic surfactant ratio in the mixtures. Remarkably, the incorporation of cholesterol in those catanionic vesicles reduces their cytotoxicity and increases the safety of future biomedical applications of these systems.

On the possibility of using temperature to aid in thyroid nodule investigation.

Thyroid nodules are common, and their investigation is very important to exclude the possibility of cancer. The increase in blood vessels of malignant tumours may be related to local temperature augmentation detectable on the skin surface. The objective of this paper is to evaluate the feasibility of Infrared Thermography for cancer identification. For this purpose, two studies were performed. One used numerical modelling to simulate regional metabolic temperature propagation to evaluate whether a nodule is perceptible on the skin surface. A second study considered thyroid nodule identification by using convolutional neural networks (CNNs). First, variations in nodular size and fat thickness were investigated, showing that the fat layer has an important role in regional heat transfer. In the second study, the training process achieved accuracy of 96% for in-sample and 95% for validation. In the testing phase, 92% accuracy, 100% precision and 80% recall were achieved. Thus, the presented studies suggest the feasibility of using Infrared Thermography with the CNN Artificial Intelligence technique as additional information in the investigation of thyroid nodules for patients without a very thick subcutaneous fat layer.

Effect of non-oxidative plasma treatments on the surface properties of poly(p-phenylene terephthalamide) (PPTA) and poly(p-phenylene benzobisoxazole) (PBO) fibres as measured by inverse gas chromatography.

It has been shown in previous works that the interfacial adhesion in PPTA- and PBO-epoxy composites can be improved by modifying the surface properties of these high-performance fibres upon exposure to non-oxidative plasma treatments. In this work, the effects developed on both types of polymer surface were examined as a function of treatment gas nature (He or N2) and exposure time (one or four minutes) using inverse gas chromatography at infinite dilution (IGC). From the adsorption of n-alkanes, it has been proved that non-oxidative plasma treatments led to energetically heterogeneous surfaces in the case of PPTA, and to low-energy surfaces in the case of PBO. Nevertheless, it was proved with the 1-min plasma treatments (either under helium or under nitrogen) that chemical reactivity was enhanced on the PBO surface. Such a behaviour was ascribed to the presence of low-molecular weight oxidized materials. The mechanisms involved in surface activation of PPTA were not equivalent under He or N2 exposure. Nitrogen plasma exposure led to a PPTA surface that is chemically reactive as a result of polarity enhancement. Helium plasma-treated PPTA surface was characterized by the presence of branched arrangements that intensified the number of chemical contacts onto reactive sites. Finally, for both fibre sets, if the purpose is to enhance the chemical surface reactivity, it makes no sense to increase the plasma exposure time from 1 to 4 min.

Addressing Quality of Life of Children With Autism Spectrum Disorder and Intellectual Disability.

Despite the advances on the assessment of quality of life, this concept is barely studied and is riddled with important limitations for those with autism spectrum disorder (ASD). This article is aimed at validating a questionnaire to assess quality of life of children with ASD and intellectual disability (ID). Based on the KidsLife Scale, geared toward people with ID, the most reliable items for those with ASD were selected. Study participants were 420 persons, from 4 to 21 years old. Results indicated that the KidsLife-ASD Scale measured eight intercorrelated domains, had good reliability, and exhibited adequate evidences of validity. KidsLife-ASD emerges as a helpful tool to guide person-centered planning addressed at improving quality of life.

Shellfish Allergy: Unmet Needs in Diagnosis and Treatment.

Seafood is a major cause of food allergy and anaphylaxis worldwide. Shellfish is included among the "big eight" food groups, which are responsible for more than 90% of all cases of food allergy. Approximately 2.5% of the world's population has experienced an adverse reaction to seafood. Seafood allergy is one of the most frequent and lethal allergies that exist. The several allergenic proteins involved in allergic reactions that have been described in recent years include tropomyosin, arginine kinase, myosin light chain, and sarcoplasmic calcium-binding protein. Despite all the data reported in the last few years, shellfish allergy is still diagnosed and treated as it was 50 years ago. The only effective treatment to prevent allergic reactions to shellfish is avoidance. This review aims to update recently published data on shellfish allergy and to highlight those areas that have yet to be resolved.
