Authors: Garner Amy J. , Edwards Thomas C. , Liddle Alexander D. , Jones Gareth G. , Cobb Justin P. 
Published: August 2021

Aims Joint registries classify all further arthroplasty procedures to a knee with an existing partial arthroplasty as revision surgery, regardless of the actual procedure performed. Relatively minor procedures, including bearing exchanges, are classified in the same way as major operations requiring augments and stems. A new classification system is proposed to acknowledge and describe the detail of these procedures, which has implications for risk, recovery, and health economics. Methods Classification categories were proposed by a surgical consensus group, then ranked by patients, according to perceived invasiveness and implications for recovery. In round one, 26 revision cases were classified by the consensus group. Results were tested for inter-rater reliability. In round two, four additional cases were added for clarity. Round three repeated the survey one month later, subject to inter- and intrarater reliability testing. In round four, five additional expert partial knee arthroplasty surgeons were asked to classify the 30 cases according to the proposed revision partial knee classification (RPKC) system. Results Four classes were proposed: PR1, where no bone-implant interfaces are affected; PR2, where surgery does not include conversion to total knee arthroplasty, for example, a second partial arthroplasty to a native compartment; PR3, when a standard primary total knee prosthesis is used; and PR4 when revision components are necessary. Round one resulted in 92% inter-rater agreement (Kendall’s W 0.97; p < 0.005), rising to 93% in round two (Kendall’s W 0.98; p < 0.001). Round three demonstrated 97% agreement (Kendall’s W 0.98; p < 0.001), with high intra-rater reliability (interclass correlation coefficient (ICC) 0.99; 95% confidence interval 0.98 to 0.99). Round four resulted in 80% agreement (Kendall’s W 0.92; p < 0.001). Conclusion The RPKC system accounts for all procedures which may be appropriate following partial knee arthroplasty. It has been shown to be reliable, repeatable and pragmatic. The implications for patient care and health economics are discussed. Cite this article: Bone Jt Open 2021;2(8):638–645.

Objective: to identify the prognostic aspects of the ischemic stroke (IS) focus characteristics according to the data of computed tomography of the brain.Patients and methods. We examined 80 patients with hemispheric IS up to 1-day old (50 patients for constructing mathematical models of disease outcomes and 30 patients for subsequent testing of the obtained models) aged 30-84 years.Results and discussion. The analysis of the association between mortality probability and brain midline shift size shown that a brain midline shift of 4.5-5 mm did not increase mortality probability much, which indicates the synergistic stability of this system. System destabilization began after an increase of the brain midline shift for more than 5-5.5 mm. After a mild change in the initial indicator (6-8 mm), mortality probability increased from 25% to 90% and higher. When the brain midline shift was more than 8.5 mm, the system, from the synergistic viewpoint, became stable again but with an unfavorable prognosis. This analysis helps to identify the critical decision-making point when analyzing the IS focus neuroimaging characteristics. Thus, the point for the focus volume is 145 cm3, and for the brain midline shift - 5.0 mm.Conclusion. The results of our study about the prognostic value of the IS focus characteristics according to CT data may have additional value for decision-making in the management of patients with a poor prognosis.
Solving Multi-Objective Energy Management of a DC Microgrid using Multi-Objective Multiverse Optimization
Authors: Lagouir Marouane , Badri Abdelmajid , Sayouti Yassine 
Published: August 2021

This paper deals with the multi-objective optimization dispatch (MOOD) problem in a DC microgrid. The aim is to formulate the MOOD to simultaneously minimize the operating cost, pollutant emission level of (NOx, SO2 and CO2) and the power loss of conversion devices. Taking into account the equality and inequality constraints of the system. Two approaches have been adopted to solve the MOOD issue. The scalarization approach is first introduced, which combines the weighted sum method with price penalty factor to aggregate objective functions and obtain Pareto optimal solutions. Whilst, the Pareto approach is based on the implementation of evolutionary multi-objective optimization solution. Single and multi-objective versions of multi-verse optimizer algorithm are, respectively, employed in both approaches to handle the MOOD. For each time step, a fuzzy set theory is selected to find the best compromise solution in the Pareto optimal set. The simulation results reveal that the Pareto approach achieves the best performances with a considerable decrease of 28.96 $/day in the daily operating cost, a slight reduction in the power loss of conversion devices from 419.79 kWh to 419.29 kWh, and in less computational time. While, it is noticing a small increment in the pollutant emission level from 11.54 kg/day to 12.21 kg/day, for the daily microgrid operation. This deviation can be fully covered when comparing the cost related to the treatment of these pollutants, which is only 5.55 $/day, to the significant reduction in the operating cost obtained using the Pareto approach.

Abstract
Nachhaltigkeitsanalysen von Produktionssystemen betrachten diverse interdisziplinäre Einflüsse aus Ökonomie, Umwelt, Qualität und Sozialem. Häufig werden jedoch einzelne Nachhaltigkeitsaspekte beachtet und nicht das Gesamtsystem. Dessen Potenziale und Risiken bleiben so unentdeckt. Mithilfe der dynamischen Nachhaltigkeitsanalyse ist es möglich, eine Entscheidungsassistenz zu entwickeln, welche die relevanten Faktoren der Nachhaltigkeit vereint betrachtet und operative Interaktionen sichtbar macht.

Background and Purpose:
Falls are a common and persistent concern among people with neurological disorders (PwND), as they frequently result in mobility deficits and may lead to loss of functional independence. This study investigated the ceiling and floor effects, internal consistency, and convergent validity of 2 patient-reported fall prevention strategy scales in PwND.

Methods:
This is a prospective cohort study. Two-hundred and ninety-nine PwND (111 people with multiple sclerosis, 94 people with Parkinson's disease, and 94 people with stroke) were seen for rehabilitation and assessed. The number of retrospective and prospective falls, use of walking assistive devices, scores on the Fall Prevention Strategy Survey (FPSS), Falls Behavioural Scale (FaB), and balance and mobility scales (Berg Balance Scale, Dynamic Gait Index, Timed Up and Go, 10-m walking test, and Activities-specific Balance Confidence) were analyzed.

Results:
Total score distributions showed negligible ceiling and floor effects for both the FPSS (ceiling: 0.3%, floor: 0.3%) and the FaB (ceiling: 0%, floor: 0%). The Cronbach α (CI) was of 0.87 (0.85-0.89) for the FPSS and 0.86 (0.84-0.88) for the FaB. In terms of convergent validity, the FPSS and FaB were moderately correlated (Spearman correlation coefficient = 0.65). Moreover, the correlations between the FPSS and FaB and balance and mobility scales ranged from 0.25 to 0.49 (P < .01). Both scales are slightly better able to distinguish between retrospective fallers/nonfallers [area under the curve, AUC (95% CI): FPSS: 0.61 (0.5-0.7); FaB: 0.60 (0.5-0.6)] compared with prospective fallers/nonfallers [AUC (95% CI): FPSS: 0.56 (0.4-0.6); FaB: 0.57 (0.4-0.6)]. Both scales accurately identified individuals who typically required the use of a walking assistive device for daily ambulation [AUC (95% CI): FPSS: 0.74 (0.7-0.8); FaB: 0.69 (0.6-0.7)]. Multiple regression analysis showed that previous falls, use of an assistive device, and balance confidence significantly predicted participants' prevention strategies (FPSS: R
2 = 0.31, F
(8,159) = 10.5, P < .01; FaB: R
2 = 0.31, F
(8,164) = 10.89, P < .01).

Conclusion:
The FPSS and the FaB appear to be valid tools to assess fall prevention strategies in people with neurological disorders. Both scales provide unique and added value in providing information on individual behavior for fall prevention.

Aim The aim of this study was to investigate the short-term effect of the COVID-19 pandemic on the management of warfarin therapy used for atrial fibrillation (AF) and prosthetic valve disease.Material and methods The study included 139 Atrial fibrillation (AF) patients and 173 prosthetic valve patients (PVP) who were using warfarin. The time in therapeutic range (TTR), International Normalized Ratio (INR) averages, the numbers of INR tests, and the non-adherence to INR monitoring (NIM) were compared for the pre-covid period (PCP) and the COVID-19 period (CP). Also, adherence to warfarin therapy was evaluated with a questionnaire.Results For all patients, the INR values were higher in the CP (2.47 vs 2.60, p<0.001), and the NIM percentage was higher (19.2 % vs 71.5 %, p<0.001) in the CP. The number of INR tests was lower during the CP (p<0.001).The percentage of patients with TTR≥70 % was lower during the CP (41.7 % vs 33 % p=0.017). Subgroup analysis showed that for PVP, TTR values and the percentage of patients with TTR ≥70 % were similar in both the PCP and CP periods. The questionnaire showed that for 94.1 % of respondents, the major cause of NIM in the CP was the COVID-19 pandemic. However, during the CP, adherence to warfarin medication was high (95.5 %).Conclusion Lower TTR during the COVID-19 pandemic can increase bleeding and thromboembolic cases.Therefore, patients taking warfarin should be followed more closely, and more practical ways should be considered for INR testing.

Published: August 2021

Background: Diabetes mellitus is a chronic, degenerative disease, requiring a multi-dimensional, multi-professional care by healthcare providers and substantial self-care by the patients, to achieve treatment goals.
Objective: To evaluate the impact of pharmacist-led care on glycaemic control in patients with uncontrolled Type 2 Diabetes
Methods: In a parallel group, single-blind randomised controlled study; type 2 diabetic patients, with greater than 7% glycated haemoglobin (A1C) were randomised into intervention and usual care groups and followed for six months. Glycated haemoglobin analyzer, lipid analyzer and blood pressure monitor/apparatus were used to measure patients’ laboratory parameters at baseline and six months. Intervention group patients received pharmacist-structured care, made up of patient education and phone calls, in addition to usual care. In an intention to treat analysis, Mann-Whitney U test was used to compare median change at six months in the primary (A1C) and secondary outcome measures. Effect size was computed and proportion of patients that reached target laboratory parameters were compared in both arms.
Results: All enrolled participants (108) completed the study, 54 in each arm. Mean age was 51 (SD 11.75) and majority were females (68.5%). Participants in the intervention group had significant reduction in A1C of -0.75%, compared with an increase of 0.15% in the usual care group (p<0.001; eta-square= 0.144). The proportion of those that achieved target A1C of <7% at 6 months in the intervention and usual care group was 42.6% vs 20.8% (p=0.02). Furthermore, intervention patients were about 3 times more likely to have better glucose control; A1C<7% (aOR 2.72, 95%CI: 1.14-6.46) compared to usual care group, adjusted for sex, age, and duration of diabetes.
Conclusions: Pharmacist-led care significantly improved glycaemic control in patients with uncontrolled T2DM.

Tanah Laut District has been designated by the Ministry of Forestry as an area for developing Leading Non-Timber Forest Products (HHBK) in the form of honey bee cultivation. This is in line with the local government policy of Tanah Laut Regency through the Decree of the Regent of Tanah Laut Number: 188.45 / 463-KUM / 2013 which stipulates honey as the leading NTFP in Tanah Laut. The types of honey that are cultivated are bees Apis cerena, Apis mellifera and Kelulut (Trigona itama). Dusun Trans Kopi Telaga Langsat, Tanah Laut district is one of the areas where there are farmers who practice kelulut honey bee cultivation. However, so far there has been no information or study results that show how feasible the honey cultivation business is carried out by kelulut honey bee farmers in this area. This research aims were analyzed the feasibility of honey bee cultivation and its contribution to farmer household income. The data collected in this research were done by interviewing and observing. The analyzed of data had been obtained by BCR formula (Benefit Cost Ratio) to determine the feasibility of the business. The contribution of business was conducted to determine how much contribution of kelulut honey bee cultivation for farmers' household income. The results showed that the business carried out by Yamani's kelulut honey bee business had a BCR value of 5.72 with a contribution to household income of 16.77%. Meanwhile, Rudi's kelulut honey bee business has a BCR of 8.73 with a contribution to household income of 8.99%. Kelulut honey bee cultivation which is carried out by the two farmers is a type of business that is worthy of investment because the value of each BCR is more than 1 (BCR> 1).

This single-blind and cross-sectional study evaluated the role of Rho-kinase (ROCK) as a biomarker of the cardiovascular remodelling process assessed by echocardiography in competitive long-distance runners (LDR) during the training period before a marathon race. Thirty-six healthy male LDR (37.0±5.3 years; 174.0±7.0 height; BMI: 23.8±2.8; VO2-peak: 56.5±7.3 mL·kg-1·min-1) were separated into two groups according to previous training level: high-training (HT, n=16) ≥100 km·week-1 and low-training (LT, n=20) ≥70 and &amp;lt;100 km·week-1. Also, twenty-one healthy nonactive subjects were included as a control group (CTR). A transthoracic echocardiography was performed and ROCK activity levels in circulating leukocytes were measured at rest (48-hr without exercising) the week before the race. HT group showed higher left ventricular mass index (LVMi) and left atrial volume index (LAVi) than other groups (p&amp;lt;0.05, for both), also higher levels of ROCK activity were found in LDR (HT=6.17±1.41 vs CTR=1.64±0.66 (p&amp;lt;0.01); vs LT=2.74±0.84; (p&amp;lt;0.05)). In LDR a direct correlation between ROCK activity levels and LVMi (r=0.83; p&amp;lt;0.001), and LAVi (r=0.70; p&amp;lt;0.001) were found. In conclusion, in male competitive long-distance runners, the load of exercise implicated in marathon training is associated with ROCK activity levels and the left cardiac remodelling process assessed by echocardiography.
