Abstract
Background: Utilizing intrawound vancomycin powder in TKA surgery has yielded rather contrasting results in the current literature. Furthermore, CDC criteria, although effective in general, are not specifically designed for post-TKA infections. Here, we present a 7-year experience of vancomycin use in primary TKA in a high-volume tertiary knee center in Iran. Also, new criteria are proposed to detect suspected superficial post-TKA infections. Methods: This is a retrospective analysis of primary total knee arthroplasties performed in a tertiary knee center, from March 2007 to December 2018, by a single senior knee surgeon. All patients with follow-up periods of less than one year were excluded from the study. Since March 2011, all patient received vancomycin (powder, 1gr) before water-tight closure of the joint capsule. Comparison was made between this group and historical control subjects (operated from March 2007 to March 2011). Results: Altogether, 2024 patients were included in the study. The vancomycin and the control group included 1710 and 314 cases respectively. Patients were mostly women (male to female ratio: 1 to 4), with a mean age of 65.20 (SD=10.83) years. In the vancomycin group, the rate of suspected SII (1.87%) and PJI (0.41%) was significantly lower than the control group (P= 0.002). Conclusions: Our experience shows that by utilizing intrawound vancomycin as a routine practice along with other measures, we were able to reach relatively low rates of deep post-TKA infections. Howbeit, randomized controlled trials are required to clarify the effect of intrawound vancomycin on post-TKA infection rate.

Abstract
Background: ﻿The diagnosis of infective endocarditis (IE) remains a clinical challenge. Diagnostic accuracy of the modified Duke criteria is suboptimal for native valve endocarditis (NVE) and even worse in the presence of prosthetic material-related infection (PVE). We aim to evaluate the diagnostic performance of 18F-FDG PET in patients with suspected IE referred to perform PET/CT.Methods: Consecutive patients with suspected IE, referred to perform PET/CT between May 2016 and June 2019 were included. Diagnostic performance of modified Duke criteria (mDC) and PET/ CT for IE for NVE and PVE was determined.Results: In total, 82 patients (mean age of 61 ± 19 years, 62% of male gender) were enrolled. There were 67 18F-FDG PET/CT concordant results with final diagnosis, corresponding to a 96% of agreement, k=0.91(p=0.04). A SUV max cutoff value of ≥3.1 identified positive cases with 88.9% sensitivity and 70.0% specificity. In patients with NVE, the addition of PET/CT to the mDC resulted in a reduction of the number of possible IE cases (from 58% to 4.3%). In patients with PVE/intracardiac devices, PET/CT allowed reclassification of 67.4% of possible cases to 4.2%. An alternative diagnosis was provided in 55.6% of the negative IE cases.Conclusions: 18F-FDG PET/CT proved to be a useful diagnostic tool in patients with both suspected NVE and PVE with good sensitivity and specificity, resulting in a significant decrease of the number of possible endocarditis. Furthermore, it allowed the identification of the cause of clinical scenario in more than 50% of patients in which the diagnosis was excluded.

Abstract
Background: Injury is one of the major public health problems and causes more than 5 million deaths in the world annually. Cases of specific types of injury are life-threatening and heavily-burdened to individuals and society. This study was aimed to assess the financial burden of injury on patients. Methods: A total of 565 medical institutions were selected with multistage stratified cluster random sampling, containing 152553 valid samples. Subsequently, the distribution of injury current curative expenditure (CCE) in different dimensions (including age and site of injury) was analyzed under the framework of System of Health Accounts 2011 (SHA 2011) using the established database. Results: In China, both urban and rural injury mortality rates showed an upward trend of more than 5 percentage points from 2006 to 2016. In Dalian, the CCE of injury reached 1572.73 million RMB, accounting for 7.45% of the total CCE. Those aged 15-24 reported larger proportion of CCE than the other age groups. As for the injuries in body parts, injuries occurred to the spine, lower limb, head and foreign body cost most.Conclusions: Dalian has a relatively serious burden of injury costs. The essential and primary goal is to reduce the cost. Young people should pay attention to protect their head and limbs from injury, and related government sectors should implement preventive and educative measures.

Abstract
Background: There is limited information about the psychosocial sub-determinants regarding the use of HIV Testing and Counselling (HTC) services among suspected Tuberculosis (TB) patients in Sudan. This study aimed to assess the association between psychosocial beliefs and the intention to use HTC services and to establish the relevance of these beliefs for developing behaviour change interventions among suspected TB patients Methods:Suspected TB patients (N= 383) from four separate TB facilities completed a cross-sectional questionnaire which was based on the Reasoned Action Approach theory. Eligibility criteria included attending Tuberculosis Management Units in Kassala State as suspected TB patients and aged 18-64 years. A Confidence Interval Based Estimation of Relevance (CIBER) analysis approach was employed to investigate the association of the beliefs with the intention to use HTC services and to establish their relevance to be targeted in behaviour change interventions.Results: The CIBER results showed the beliefs included in the study accounted for 59% to 70% of the variance in intention to use HTC services. The belief "My friends think I have to use HTC services" was positively associated with the intent to use HTC, and it is highly relevant for intervention development. The belief “I would fear to be stigmatized if I get a HIV positive result" was negatively related to the intention to use HTC services and was considered a highly relevant belief. The belief “If I use HTC services, health care providers will keep my HIV test result confidential" was strongly associated with the intention to use HTC services. However, the relevance of this belief as a target for future interventions development was relatively low. Past experience with HTC services was weakly associated with the intention to use HTC services.Conclusion: The intention to use HTC was a function of psychosocial beliefs. The beliefs investigated varied in their relevance for interventions designed to encourage the use of HTC services. Interventions to promote intention to use HIV testing and counselling services should address the most relevant beliefs (sub-determinants). Further study is needed to establish the relevance of sub-determinants of the intention to use HTC services for interventions development.

Abstract
Background: Recent cardiovascular outcome trials have shown significant reductions in major cardiovascular (CV) events with glucagon-like peptide (GLP)-1 receptor agonists. Additionally, adjunctive surrogates for cardiovascular risk validated by some studies include arterial stiffness and endothelial function indexes. To date, no randomized trial has addressed the possible effects of antidiabetic interventional drugs such as GLP1 agonists on endothelial and arterial stiffness indexes as surrogate markers of vascular damage. Aims: We aimed to evaluate metabolic efficacy and surrogate vascular efficacy endpoints of once-weekly dulaglutide (1.5 mg) plus traditiona antidiabetic treatment compared with traditional antidiabetic treatment alone in subjects with type 2 diabetes. Methods: Men and women (aged ≥50 years) with established or newly detected type 2 diabetes whose HbA1c level was 9.5% or less on stable doses of up to two oral glucose­lowering drugs with or without basal insulin therapy were eligible for randomization. Subcutaneous dulaglutide was initiated at the full dose (1.5 mg/day weekly). Arterial stiffness (PWV: pulse wave velocity and augmentation index) and endothelial function (RHI: reactive hyperaemia index) were evaluated at baseline and at three-month and nine-month examination visits. At each visit (at 3 and 9 months), the subjects were also evaluated for glycaemic variables such as fasting plasma glucose (FPG) and HbA1c and lipid variables such as total cholesterol, LDL cholesterol, HDL cholesterol and triglyceride levels. Results: At the three-month follow-up, the subjects treated with dulaglutide showed significantly lower serum levels of FPG and HbA1c than control subjects treated with conventional therapy. At the 9-month follow-up, subjects treated with dulaglutide showed significant lower values of the mean diastolic blood pressure, BMI, total serum cholesterol, LDL cholesterol, FPG, HbA1c and PWV and higher mean RHI values than control subjects treated with conventional therapy . Conclusions: Our randomized trial showed that subjects with type 2 diabetes treated with conventional therapy plus 1.5 mg/day of subcutaneous dulaglutide compared with subjects treated with conventional therapy alone showed favourable metabolic effects associated with positive effects on vascular health markers such as arterial stiffness and endothelial function markers. These findings are consistent with previous study findings indicating the strict relationship between cardiovascular risk factors such as systolic blood pressure, total serum cholesterol and LDL levels and cardiovascular events and vascular health surrogate markers.

Abstract
Background: Erectile dysfunction (ED) has often been observed in patients with obstructive sleep apnea (OSA). Research on adipose-derived mesenchymal stem cells (ADSCs)-derived exosomes has shown that they have significant therapeutic effects in many diseases including ED. Methods: In this study, ED was induced in Sprague Dawley (SD) rats using chronic intermittent hypoxia (CIH) exposure. CIH-mediated influences were then measured in the corpus cavernous smooth muscle cells (CCSMCs). Results: Our data showed that miR-301a-3p-enriched exosomes treatment significantly recovered erectile function in rats and CCSMCs by promoting autophagy and inhibiting apoptosis. The treatment also significantly recovered the level of alpha Smooth Muscle Actin (α-SMA) in rats and CCSMCs. Bioinformatics predicted that Phosphatase and tensin homolog (PTEN) and Toll-like receptor 4 (TLR4) might be targets of miR-301a-3p. Conclusions: Our results indicate that PTEN-overexpression vectors or TLR4-overexpression vectors reverse the therapeutic effects achieved by miR-301a-3p in CCSMCs indicating that PTEN/HIF-1α and TLR4 signaling pathways play key roles in the progression of ED. The findings in this study suggest that miR-301a-3p should be considered as a new therapeutic target for treating ED associated with OSA.

Abstract
Background: Thoracic ossification of ligamentum flavum (T-OLF), as one of the causes of thoracic myelopathy, is often combined with other spinal disorders. Concurrent lumbar spinal canal stenosis (LCS) is often obscured by symptoms due to T-OLF, leading to difficulty in identifying the origin of these neurological findings. It is common to be misdiagnosed or delayed diagnosis due to the complicated nature. We evaluated the prevalence, distribution, and clinical characteristics of OLF, especially in patients with LCS.Methods: The authors performed a retrospective analysis of the outcomes of 61 patients who underwent thoracic surgeries performed for symptomatic T-OLF. In all the patients, whole spine lesions were evaluated preoperatively. We examined the factors related to poor outcomes (the recovery rate of the Japanese Orthopedic Association score for thoracic myelopathy is less than 40%) following OLF surgeries. We compared the clinical outcomes according to whether there was concurrent LCS, and determined the optimal surgical approach.Results: The occurrence of T-OLF increased with age. Forty-six cases (75.4%) were considered to be tandem T-OLF and LCS (LCS group). An advanced age, and concurrent LCS were associated with a poor outcome after the surgery. The LCS group significantly included a greater number of elderly, and more light-weighted patients with Modic change in thoracic spine and a greater sagittal vertical axis, resulting in the lower neurological recovery. Additional lumbar surgery (13cases) effectively improved both the T-JOA and L-JOA scores (from 6.5 ± 2.0 points to 8.0 ± 1.8 points, p=0.0406, and from 14.5 ± 4.7 points to 20.7 ± 2.6 points, p=0.001, respectively) in OLF patients with LCS.Conclusions: T-OLF was highly associated with other spinal disorders. Poor outcomes in T-OLF surgery could be associated with age and concurrent LCS, and an additional surgery for another lumbar lesion significantly improved neurological findings in T-OLF patients.

Abstract
Background: For interventions to reach those they are intended for, an understanding of the factors that influence their participation, as well as the facilitators and barriers of participation are needed. This study explores factors associated with participation in a combination HIV prevention intervention targeting adolescent girls and young women (AGYW) aged 15-24-years-old, as well as the experiences of AGYW, intervention implementers, and facilitators in this intervention. Methods: This study used mixed-methods approach with quantitative household survey data from 4399 AGYW aged 15-24-years-old in six of the ten districts in which the intervention was implemented. In addition, qualitative methods included semi-structured in-depth interviews and focus group discussions in five of the ten intervention districts with 185 AGYW who participated in one or more of the key components of the intervention, and 13 intervention implementers and 13 facilitators. Results: Findings reveal that almost half of AGYW (48.4%) living in the districts where the intervention took place, participated in at least one of the components of the intervention. For both 15-19-year-olds and 20-24-year-olds, factors associated with increased participation in the intervention included being HIV negative, in school, never been pregnant, and having had a boyfriend. Experiencing intimate partner violence (IPV) and/or sexual violence in the past 12 months was associated with increased levels of participation in the intervention for 20-24-year-olds only. In our analysis of the qualitative data, facilitators to participation included motivating participants to join the interventions through explaining the benefits of the programme. Barriers included misguided expectations about financial rewards or job opportunities; competing responsibilities, interests or activities; family responsibilities including childcare; inappropriate incentives; inability to disrupt the school curriculum and difficulties with conducting interventions after school hours due to safety concerns; miscommunication about meetings; as well as struggles to reach out-of-school AGYW. Conclusion: Designers of combination HIV prevention interventions need to address the structural barriers to participation so that AGYW can attend without risking their safety and compromising their family, childcare and schooling responsibilities. Strategies to create demand need to include clear communication about the nature and potential benefits of such interventions, and the inclusion of valued incentives.

Published: December 2020

Abstract
Background: Considering the reports of increasing sleep problems in children, affecting health and well-being in young children and their families, we found it important to gain more knowledge about sleep and its correlation to health-related quality of life (HRQoL) in young, healthy children. The aims with this study were to describe sleep quality, sleep duration, and HRQoL in healthy 3–10-year-old children and to test associations between children’s sleep and HRQoL. Methods: Parents of 160 children (average age: 6.9 years, SD ±2.2) participated in the study. Sleep onset problems (SOP), sleep maintenance problems (SMP), and sleep duration were measured by the Pediatric Insomnia Severity Index (PISI). KIDSCREEN-27 was used to measure HRQoL in five dimensions: physical well-being, psychological well-being, autonomy and parent relation, social support and peers, and school environment. Results: The average score was 2.2 for SOP (SD +/-2.2) and 1.3 for SMP (SD +/-1.6). Few children (2%) were reported to sleep less than eight hours per night. Younger children had statistically significant higher SOP and SMP than older children. Correlations were found between SOP and poor psychological well-being (p < 0.05, ρ = - 0.16), and between SMP and poor physical wellbeing (p < 0.05, ρ = -0.16), psychological well-being (p < 0.05, ρ = - 0.21), poor school environment (p < 0.01, ρ = - 0.29), autonomy and parent relation (p < 0.05, ρ = - 0.16), and poor social support and peers (p < 0.05, ρ = - 0.19).Conclusion: Children’s sleep associates with health-related quality of life and needs to be acknowledged in child health care settings and schools.

Abstract
A simple fabrication of end-bonded contacts InAsSb NW (nanowire) array detector to weak light is demonstrated in this study. The detector is fabricated using InAsSb NW array grown by molecular beam epitaxy on GaAs substrate. The MIGS (metal-induced gap states) is induced by the end-bonded contact which suppresses the dark current at various temperatures. The existence of the interface dipole due to the interfacial gap states enhances the light excitation around the local field, thus upgrade the photo responsivity and photo detectivity to the weak light. The light intensity of the infrared light source in this report is 14 nW/cm2 which is about 3 to 4 orders of magnitude less than the laser source. The responsivity of the detector has reached 28.57 A/W at room temperature with the light (945 nm) radiation, while the detectivity is 4.81×1011 cm·Hz1/2 W−1. Anomalous temperature-dependent performance emerges at the variable temperature experiments, and we discussed the detailed mechanism behind the non-linear relationship between the photoresponse of the device and temperatures. Besides, the optoelectronic characteristics of the detector clarified that the light trapping effect and photogating effect of the NWs can enhance the photoresponse to the weak light across ultraviolet to near-infrared. These results highlight the feasibility of the InAsSb NW array detector to the infrared weak light without a cooling system.

Published: December 2020

The article studies the current economic situation in Russia: problems of economy development, the role of stateowned corporations and small and medium business in economy, problems of their interaction and key lines in development in the near future. The structure of domestic product of the country was described, as well as the role of certain industries of business in its formation. The chief goal of state is to re-orientate from resource-mining to resource – processing, which complies with the concept of added value and shall ensure the sustainable development of economic growth. The authors come to the conclusion that only interaction of big, medium and small business in the country can provide certain success in development, that human factor, interest of workers in results of enterprise work can become a decisive factor on the current stage. Key vectors of economy development in Russia have been identified. It was underlined that state must become an important regulator of market processes in the country. Today Russia must choose its future strategy: it can be either an inertial way of neo-liberal reforms and degrading of scientific potential or mobilization of intellectual resources to restructure economy on principles of developed market with the leading role of state.
