ABSTRACT
BACKGROUND: Shame is a powerful negative emotion that has the potential to affect health. Due to the intimate nature of breast cancer treatment and its impact on body image, it is hypothesised that shame may be experienced during treatment. The aim of this study was to explore shame experiences related to clinical encounters for breast cancer treatment. METHODS: People with a lived experience of breast cancer were invited to anonymously share their stories of shame through an online survey. Using qualitative methodology, the stories were examined, and themes identified. PARTICIPANTS: Participants were members of the consumer organisation Breast Cancer Network Australia. RESULTS: Stories were contributed by 38 participants. Most (n = 28, 73.7 %) were >5 years post-diagnosis. Shame was experienced in a range of clinical settings (consulting rooms, wards, operating theatres, radiotherapy departments). They involved a different health professionals (oncologists, surgeons, nurses, radiation therapists, psychologists.) Five themes were identified: (1) Body shame (sub-themes: Naked/vulnerable and Weight), (2) Communication (subthemes: Lack of compassion/impersonal manner and Not listening), (3) Being blamed (subthemes: diagnosis and complications), (4) Feeling unworthy (subthemes: Burden to staff and Unworthy of care), (5) Judgement for treatment choices. CONCLUSIONS: Shame can be experienced in a range of situations, from scrutiny of the naked body to comments from health professionals. The impact of these experiences is profound, and the feelings of shame are carried for many years. These findings can inform strategies to support consumers and educate health professionals with the aim of reducing harm related to cancer treatment.

UV-C at 254â¯nm and vacuum UV (VUV) at 185â¯nm are the two major emission lines of a low-pressure mercury lamp. Upon absorption of VUV photons, water molecules and selected inorganic anions generate hydroxyl (HO.) and other redox radicals, both capable of degrading organic micropollutants (OMPs), thereby offering the opportunity to reduce H2O2 and energy consumption in UV-based advanced oxidation process (AOP). To be successfully scaled-up, the dual-wavelength VUV+UV/H2O2 AOP requires laboratory-scale experiments to establish design criteria. The figures of merit typically used for reporting and interpreting quasi-collimated beam results for UV-based AOPs (time, dose, absorbed energy and EEO) are insufficient and inaccurate when employed for dual-wavelength AOP such as the VUV+UV/H2O2 AOP, and do not support system scale-up. In this study, we introduce a novel figure of merit, useful absorbed energy (uAE), defined as fraction of absorbed energy that results in the generation of oxidative radicals. Here, results of quasi-collimated beam VUV+UV/H2O2 AOP experiments on four different water matrices are used to introduce 2D plots that employ both uAEUV and uAEVUV as a novel method to represent laboratory-scale experiments of VUV+UV/H2O2 AOP and demonstrate how the 2D plots sufficiently support scale-up of the AOP.
ABSTRACT
BACKGROUND: One in three women experience sexual violence during their lifetime; however, little is known about this phenomenon with respect to justice-involved Latina mothers. Using the reproductive justice framework as a theoretical lens, we examined sexual violence in Latina mothers who had experienced incarceration and were thus involved in the justice system. METHODS: This was a secondary analysis of a qualitative data set. The reproductive justice framework provided a theoretical lens for examining the women's rights to bodily autonomy, to have or not have children, and to live in safe, sustainable environments given the intersection of incarceration and sexual violence. RESULTS: Women (N = 12) recounted their experiences of sexual violence after having been incarcerated. Incarceration and resulting sexual violence led to discrimination, limited bodily autonomy, sexual exploitation, substance use, depression, anxiety, re-traumatization, recidivism, underreporting of violence, underutilization of healthcare resources, strained relationships, family separation, and unsafe environments. CONCLUSIONS: More research is needed to understand the social, economic, and political contexts that perpetuate sexual violence among justice-involved women. Universal healthcare, participatory research, changing cultural mindsets, decriminalization of sex work, and more comprehensive tracking and prosecution of sexual predators may be key to ending sexual violence in justice-involved mothers.

This study explored process synergies attainable by integrating a vacuum ultraviolet-based advanced oxidation process with biofiltration. A comparison using granular activated carbon or granular zeolite as filtration media were examined in context of advanced wastewater treatment for potable reuse. Six biofiltration columns, three with granular activated carbon and three with granular zeolite, were operated in parallel and batch-fed daily with nitrified secondary effluent. After achieving a pseudo-steady state through the filter columns, vacuum ultraviolet treatment was applied as pre-treatment or as post-treatment, at two different applied energies (i.e., VUV-E1=1 kWh/m3 and VUV-E10=10 kWh/m3). Once granular activated carbon had transitioned to biologically activated carbon, as determined based on soluble chemical oxygen demand removal, adsorption was still observed as the main mechanism for contaminants of emerging concern and nitrate removal. Vacuum ultraviolet pre-treatment markedly improved contaminants of emerging concern removal through the integrated system, achieving 40% at VUV-E1 and 90% at VUV-E10. When applied as post-treatment to zeolite column effluents, VUV-E1 and VUV-E10 further increased contaminants of emerging concern removal by 20% and 90%, respectively. In the zeolite system, vacuum ultraviolet pre-treatment also increased soluble chemical oxygen demand removal efficiency, indicating that higher energy vacuum ultraviolet increased biodegradability. Total prokaryotes were two-fold more abundant in biologically activated carbon than in zeolite, with vacuum ultraviolet pretreatment markedly affecting microbial diversity, both in terms of richness and composition. Media type only marginally affected microbial richness in the biofilters but showed a marked impact on structural composition. No clear relationship between compositional structure and depth was observed.

BACKGROUND: Pathologists sometimes disagree over the histopathologic diagnosis of melanoma. 'Over-calling' and 'under-calling' of melanoma may harm individuals and healthcare systems. OBJECTIVES: To estimate the extent of 'over-calling' and 'under-calling' of melanoma for a population undergoing one excision per person and to model the impact of potential solutions. METHODS: In this epidemiological modelling study, we undertook simulations using published data on the prevalence and diagnostic accuracy of melanocytic histopathology in the U.S. POPULATION: We simulated results for 10 000 patients each undergoing excision of one melanocytic lesion, interpreted by one community pathologist. We repeated the simulation using a hypothetical intervention that improves diagnostic agreement between community pathologist and a specialist dermatopathologist. We then evaluated four scenarios for how melanocytic lesions judged to be neither clearly benign (post-test probability of melanoma < 5%), nor clearly malignant (post-test probability of melanoma > 90%) might be handled, before sending for expert dermatopathologist review to decide the final diagnosis. These were (1) no intervention before expert review, (2) formal second community pathologist review, (3) intervention to increase diagnostic agreement and (4) both the intervention and formal second community pathologist review. The main outcomes were the probability of 'over-calling' and 'under-calling' melanoma, and number of lesions requiring expert referral for each scenario. RESULTS: For 10 000 individuals undergoing excision of one melanocytic lesion, interpreted by a community pathologist, a hypothetical intervention to improve histopathology agreement reduced the number of benign lesions 'over-called' as melanoma from 308 to 164 and the number of melanomas 'under-called' from 289 to 240. If all uncertain diagnoses were sent for expert review, the number of referrals would decrease from 1500 to 737 cases if formal second community pathologist review was used, and to 701 cases if the hypothetical intervention was additionally used. CONCLUSIONS: Interventions to improve histopathology agreement may reduce melanoma 'over-calling' and 'under-calling'.

INTRODUCTION: Although chylothorax is an uncommon complication following paediatric cardiothoracic surgery, it has significant associated morbidities and increased in-hospital mortality, as well as results in higher costs. A lack of prospective evidence or consensus guidelines for management of chylothorax further hinders optimal management. The aim of this survey was to characterise variations in practice in the management of chylothorax and to identify areas for future research. MATERIALS AND METHODS: A descriptive, observational survey investigating conservative management practices of chylothorax was distributed internationally to health-care professionals in paediatric intensive care and cardiology units. The survey investigated five domains: the first providing general information about health-care professionals and four domains focusing on clinical practice including diet composition and duration. RESULTS: In total, sixty-four health-care professionals completed the survey, representing 38 organisations from 16 countries. The respondents were dietitians (80%), physicians (19%), and nurses (1%). In Australia and New Zealand, management was most commonly directed by physicians' preference (67%) as compared to unit protocols in Europe (67%), United States of America (67%), and Other regions (55%). Dietitians in Australia/New Zealand, United Kingdom, and Ireland followed the most restrictive diet therapy recommending <5 g long chain triglyceride fat per day (p < 0.00001). The duration of diet therapy significantly varied between regions: Australia/New Zealand: 4 weeks (36%) and 6 weeks (43%); Europe: 4 weeks (25%) and 6 weeks (57%); and North America: 4 weeks (18%) and 6 weeks (75%) (p < 0.00001). CONCLUSIONS: This survey highlights international variations in practice in the management of chylothorax, particularly with respect to treatment duration and dietary fat restriction. Future research should include a multi-centre randomised controlled trial to inform evidence-based practice and reduce morbidity, particularly poor growth.

In addition to the clinically most relevant risk factor for glaucoma, i.e., elevated intraocular pressure (IOP), there are other factors with high relevance for the disease. Changes in the autoimmune component of the immune system are of particular importance. Clinical studies have demonstrated alterations in different autoantibodies in glaucoma patients compared to healthy controls, some of which increase in abundance/have a raised titer, but also some which have a reduced titer. These changes have a distinct potential-not only as a tool for early glaucoma detection, but also as a therapeutic option due to the documented neuroprotective effects of some of these antibodies. Several antibodies displaying lower abundance in glaucoma patients, e.g., antibodies against 14-3-3 proteins, γ/α-synuclein, or also against glial fibrillary acidic protein (GFAP), show neuroprotective effects on retinal ganglion cells in vivo and in vitro. To assess the relevance of changes detected in the immune system of glaucoma patients, "omics-based" analyses of different ocular tissues are of particular importance alongside cell culture studies. In this manner, not only samples derived from experimental studies but also samples derived from glaucoma patients in even very small amounts (e. g., tears, aqueous humor, serum, or post-mortem retina) can be analyzed in detail in terms of protein and, in particular, antibody changes. Modern mass spectrometric proteomic characterization of relevant samples will deliver valuable information concerning the understanding of molecular disease mechanisms in the coming years, thus also improving diagnosis and treatment of glaucoma.

BACKGROUND: Visual recovery is an established but poorly studied phenomenon in glaucoma. OBJECTIVE: To provide insights into functional recovery of retinal ganglion cells (RGCs) with a view to providing information on the development of forms of treatment that improve RGC function after injury. METHOD: A model of recoverable RGC function in the mouse eye, induced by short-term elevation of intraocular pressure (IOP). RESULTS: The RGCs manifest near complete functional recovery after a prolonged period of dysfunction following acute IOP elevation. Increasing age and a high fat diet were subsequently found to impair recovery, whereas exercise substantially improved recovery such that older mice recovered in a similar way to young mice. CONCLUSION: Injured RGCs have the capacity to restore function after periods of functional impairment. Therapies that specifically target injured RGCs and enhance their capacity to recover function may provide a new approach for treating glaucoma.

BACKGROUND: Although a large number of studies have identified obesity as an independent risk factor for the development of periprosthetic joint infection (PJI), the synergistic impacts of obesity with other factors on PJI remain unknown. Additionally, few studies have specifically explored the risk factors of PJI within a Chinese population. AIMS: To investigate the association between obesity and PJI in a Chinese population, and identify synergistic impacts of obesity with other risk factors on the development of PJI. METHODS: Three hundred and seven patients at a single institution with a diagnosis of PJI following primary total hip or knee arthroplasty, treated from 2008 to 2015, were identified. Each case was matched with two controls who did not develop PJI after primary total hip or knee arthroplasty in the study period using propensity score matching for several important parameters. Multi-variable logistic regression models were used to estimate the association between body mass index (BMI) and the risk of developing PJI. Interaction and stratified analyses were conducted according to age, sex, type of surgery, smoking status, alcohol use, diabetes, inflammatory arthritis, liver disease and renal disease. FINDINGS: The multiple logistic analyses showed that obesity was associated with increased risk of PJI [odds ratio (OR) 2.48; 95% confidence interval (CI) 1.66-3.69]. When analysed as a continuous variable, BMI was also associated with increased risk of PJI (OR per 1 kg/m2 increase in BMI 1.08; 95% CI 1.02-1.14). In the interaction analysis, patients who were obese and smoked had a higher OR of developing PJI than non-smokers who were obese (OR 3.54 vs 1.55, P-value for interaction=0.031). Similarly, the OR was much higher for patients with both obesity and inflammatory arthritis than for patients who were obese with no history of inflammatory arthritis (OR 3.9 vs 1.55, P-value for interaction=0.029). No other significant interactions were found in the association between obesity and PJI. CONCLUSION: Obesity is an independent risk factor for the development of PJI in the Chinese Han population. Surgeons should be aware that obese patients who smoke or have inflammatory arthritis are at additional increased risk of PJI.

BACKGROUND: Surgical wounds healing by secondary intention can be difficult and costly to manage and are profoundly under researched. This prospective inception, cohort study aimed to derive a better understanding of surgical wounds healing by secondary intention and to facilitate the design of future research investigating effective treatments. OBJECTIVES: To investigate the clinical characteristics of patients with surgical wounds healing by secondary intention and the surgeries that preceded their wounds; to clearly delineate the clinical outcomes of these patients, specifically focusing on time to wound healing and its determinants; to explore the types of treatments for surgical wounds healing by secondary intention; and to assess the impact surgical wounds healing by secondary intention have on patients' quality of life. DESIGN: Prospective, inception cohort study. SETTING: Acute and community settings in eight sites across two large centres in the United Kingdom (Hull and Leeds, UK). METHODS: Patients with a surgical wounds healing by secondary intention (an open wound, <3 weeks' duration, resulting from surgery), were recruited and followed up for at least 12 months. Key outcome events included: time to healing; treatment type; infection; hospital re-admission and further procedures; health-related quality of life and pain. RESULTS: In total, 393 patients were recruited. Common co-morbidities were cardiovascular disease (38%), diabetes (26%) and peripheral vascular disease (14.5%). Baseline median SWHSI area was 6 cm2 (range 0.01-1200). Abdominal (n = 132), foot (n = 59), leg (n = 58) and peri-anal (n = 34) wounds were common. The majority of wounds (236, 60.1%) were intentionally left open following surgery; the remainder were mostly dehisced wounds. Healing was observed in 320 (81.4%) wounds with a median time to healing of 86 days (95% CI: 75-130). Factors associated with delayed healing included wound infection at any point and baseline wound area above the median. Health-related quality of life scores were low at baseline but improved with time and healing. CONCLUSIONS: This is the first inception cohort study in patients with surgical wounds healing by secondary intention. Patient characteristics have been clearly defined, with prolonged healing times and adverse events being common impacting on patient's health-related quality of life. Areas for, and factors crucial to the design of, future research have been identified.

BACKGROUND: Several studies have compared the incidence of periprosthetic joint infection (PJI) between simultaneous bilateral total joint arthroplasty (SBTJA) and staged bilateral total joint arthroplasty (StBTJA) patients following primary total joint arthroplasty. However, these studies lacked statistical power. AIM: To determine by meta-analysis whether SBTJA increases deep infection risk compared to StBTJA. METHODS: All studies were retrieved from PubMed, Embase, Cochrane Library databases, Web of Science, PEDro, CINAHL, SPORTDiscus, and Scopus. A meta-analysis was conducted to compare PJI rate between SBTJA and StBTJA patients. FINDINGS: Overall, there were 16 studies with 36,765 patients who underwent SBTJA and 71,558 patients who underwent StBTJA. The pooled data showed that the PJI rate of SBTJA was lower than that of StBTJA (0.84% vs 1.57%; odds ratio (OR): 0.57; 95% confidence interval (CI): 0.49-0.66; heterogeneity, I2 = 0%; P = 0.74). In subgroup analysis, the pooled data revealed that there was no significant difference between SBTJA and StBTJA groups for PJI if the two groups had similar baseline demographics (four studies; OR: 0.55; 95% CI: 0.21-1.40; heterogeneity, I2 = 0%; P = 0.77). The pooled data showed that the PJI rate of SBTJA patients was comparable with that of StBTJA patients within a three-month staging interval (three studies; OR: 1.22; 95% CI: 0.38-3.88; heterogeneity, I2 = 0%; P = 0.42). CONCLUSION: SBTJA does not increase the risk of subsequent PJI compared to StBTJA. Further studies are needed to provide higher quality evidence to evaluate the two modes of procedure.

AIM: To compare systematically the impact of two novel insulin-dosing algorithms (the Pankowska Equation and the Food Insulin Index) with carbohydrate counting on postprandial glucose excursions following a high fat and a high protein meal. METHODS: A randomized, crossover trial at two Paediatric Diabetes centres was conducted. On each day, participants consumed a high protein or high fat meal with similar carbohydrate amounts. Insulin was delivered according to carbohydrate counting, the Pankowska Equation or the Food Insulin Index. Subjects fasted for 5 h following the test meal and physical activity was standardized. Postprandial glycaemia was measured for 300 min using continuous glucose monitoring. RESULTS: 33 children participated in the study. When compared to carbohydrate counting, the Pankowska Equation resulted in lower glycaemic excursion for 90-240 min after the high protein meal (p < 0.05) and lower peak glycaemic excursion (p < 0.05). The risk of hypoglycaemia was significantly lower for carbohydrate counting and the Food Insulin Index compared to the Pankowska Equation (OR 0.76 carbohydrate counting vs. the Pankowska Equation and 0.81 the Food Insulin Index vs. the Pankowska Equation). There was no significant difference in glycaemic excursions when carbohydrate counting was compared to the Food Insulin Index. CONCLUSION: The Pankowska Equation resulted in reduced postprandial hyperglycaemia at the expense of an increase in hypoglycaemia. There were no significant differences when carbohydrate counting was compared to the Food Insulin Index. Further research is required to optimize prandial insulin dosing.

BACKGROUND: Online psychotherapy has been successfully used as supportive treatment in many chronic illnesses. However, there is a lack of evidence on its role in the management of gastrointestinal (GI) diseases. AIMS: To examine whether online psychological interventions improve mental and physical outcomes in gastrointestinal diseases. METHODS: We searched CINAHL Plus, MEDLINE, EMBASE, Health Management Information Consortium, PsycINFO, British Nursing Index, Cochrane Library, a specialised register of the IBD/FBD Cochrane Group, MEDLINE (PubMed) WHO International Clinical Trial Registry, ClinicalTrials.gov, and reference lists of all papers included in the review. The Cochrane Risk of Bias Tool was used to assess internal validity. Where possible, data were pooled using random-effects meta-analysis. RESULTS: We identified 11 publications (encompassing nine studies) meeting inclusion criteria. One study had a high risk of selection bias (allocation concealment), all studies had a high risk of performance and detection bias. Eight studies were included in the meta-analyses (6 on irritable bowel syndrome [IBS] and two on inflammatory bowel disease [IBD]). Online cognitive behavioural therapy (CBT) was shown to significantly improve gastrointestinal symptom-specific anxiety (MD: -8.51, 95% CI -12.99 to -4.04, P = 0.0002) and lessen symptom-induced disability (MD: -2.78, 95% CI -5.43 to -0.12, P = 0.04) in IBS post intervention. There was no significant effect of online CBT on any other outcomes in IBS. No significant effect of online psychotherapy was demonstrated in IBD. CONCLUSION: There is insufficient evidence to demonstrate the effectiveness of online CBT to manage mental and physical outcomes in gastrointestinal diseases.

BACKGROUND: Verrucae are a common foot skin pathology, which can in some cases persist for many years. Plantar verrucae can be unsightly and painful. There are a range of treatment options including needling. OBJECTIVES: The EVerT2 (Effective Verruca Treatments 2) trial aimed to evaluate the clinical and cost-effectiveness of the needling procedure for the treatment of plantar verrucae, relative to callus debridement. METHODS: This single-centre randomized controlled trial recruited 60 participants (aged ≥ 18 years with a plantar verruca). Participants were randomized 1 : 1 to the intervention group (needling) or the control group (debridement of the overlying callus). The primary outcome was clearance of the index verruca at 12 weeks after randomization. Secondary outcomes included recurrence of the verruca, clearance of all verrucae, number of verrucae, size of the index verruca, pain and participant satisfaction at 12 and 24 weeks. A cost-effectiveness analysis was carried out from the National Health Service perspective over 12 weeks. RESULTS: Sixty eligible patients were randomized (needling group n = 29, 48%; debridement group n = 31, 52%) and 53 were included in the primary analysis (needling n = 28, 97%; debridement n = 25, 81%). Clearance of the index verruca occurred in eight (15%) participants (needling n = 4, 14%; debridement n = 4, 16%; P = 0·86). The needling intervention costs were on average £14·33 (95% confidence interval 5·32-23·35) more per patient than for debridement. CONCLUSIONS: There is no evidence that the needling technique is more clinically or cost-effective than callus debridement. The results show a significant improvement in pain outcomes after needling compared with the debridement treatment alone.

A new collimated filtered thermoluminescent dosimeter (TLD) array has been developed at the Z facility to characterize warm x-rays (hν > 10 keV) produced by Z pinch radiation sources. This array includes a Kapton debris shield assembly to protect the TLDs from the source debris, a collimator array to limit the field of view of the TLDs to the source region, a filter wheel containing filters of aluminum, copper and tungsten up to 3 mm thick to independently filter each TLD, and a hermetically sealed cassette containing the TLDs as well as tungsten shielding on the sides and back of the array to minimize scattered radiation reaching the TLDs. Experimental results from a krypton gas puff and silver wire array shot are analyzed using two different functional forms of the energy spectrum to demonstrate the ability of this diagnostic to consistently extend the upper end of the x-ray spectrum characterization from â¼50 keV to >1 MeV.
ABSTRACT
OBJECTIVES: This paper presents findings of a qualitative study of older people's use of alcohol during retirement and identifies ways that an improved understanding of older people's drinking can inform policy approaches to alcohol and active and healthy ageing. STUDY DESIGN: Qualitative semi-structured interviews conducted with a self-selecting sample of retired people. METHODS: Participants were recruited from three geographical locations in the West of Scotland. A quota sampling design was used to ensure a broad spread of participants in terms of socio-economic position, age and gender. In total 40 participants were interviewed and the data analysed thematically using Braun and Clarke's (2006) approach. RESULTS: Amongst those who used alcohol, it was most often framed in terms of pleasure, relaxation, socialising and as a way to mark the passage of time. Alcohol was often associated with social occasions and interactions both in private and in public spaces. There were also many examples of the use of imposed routines to limit alcohol use and of a decreasing volume of alcohol being consumed as participants aged. This suggests that older people are often active in constructing what they regard as 'healthier' routines around alcohol use. However, processes and circumstances associated with ageing can lead to risk of social isolation and/or increased alcohol consumption. Such processes include retirement from paid work and other 'biographical disruptions' such as caring for a partner, bereavement and/or loss of social networks. CONCLUSIONS: These findings highlight processes that can result in changes in drinking habits and routines. Whilst these processes can be associated with a reduction or cessation of alcohol use as people age, they can also be associated with increased risk of harmful alcohol consumption. Fractured or disrupted routines, particularly those associated with bereavement or the burden of caring responsibilities, through increasing the risk of loneliness and isolation, can construct increased risk of harmful alcohol consumption. These findings reframe the pathway of risk between ageing and alcohol-related harm by highlighting the vulnerability to harmful drinking practices brought by fracture or sudden change of routine. The findings point to a role for public health in supporting the reconstruction of routines that provide structure and meaning and can be used to actively manage the benefits and harms associated with drinking.

BACKGROUND CONTEXT: Various modifications to standard "rigid" anterior cervical plate designs (constrained plate) have been developed that allow for some degree of axial translation and/or rotation of the plate (semi-constrained plate)-theoretically promoting proper load sharing with the graft and improved fusion rates. However, previous studies about rigid and dynamic plates have not examined the influence of simulated muscle loading. PURPOSE: The objective of this study was to compare rigid, translating, and rotating plates for single-level corpectomy procedures using a robot testing system with follower load. STUDY DESIGN: In-vitro biomechanical test. METHODS: N = 15 fresh-frozen human (C3-7) cervical specimens were biomechanically tested. The follower load was applied to the specimens at the neutral position from 0 to 100 N. Specimens were randomized into a rigid plate group, a translating plate group and a rotating plate group and then tested in flexion, extension, lateral bending and axial rotation to a pure moment target of 2.0 Nm under 100N of follower load. Range of motion, load sharing, and adjacent level effects were analyzed using a repeated measures analysis of variance (ANOVA). RESULTS: No significant differences were observed between the translating plate and the rigid plate on load sharing at neutral position and C4-6 ROM, but the translating plate was able to maintain load through the graft at a desired level during flexion. The rotating plate shared less load than rigid and translating plates in the neutral position, but cannot maintain the graft load during flexion. CONCLUSIONS: This study demonstrated that, in the presence of simulated muscle loading (follower load), the translating plate demonstrated superior performance for load sharing compared to the rigid and rotating plates.
