Intra-articular Platelet-Rich Plasma Injections for Treating Knee Pain Associated with Articular Cartilage and Degenerative Meniscal Lesions

BACKGROUND: Platelet-rich plasma (PRP) is an autologous concentration of platelets that contain a large number of growth factors. These growth factors play a role in the regeneration, repair, and acceleration of the biochemical process, thereby reducing the pain associated with injuries of the articular cartilage and meniscus AIM: The purpose of this study is to evaluate the effect of the PRP method in the treatment of knee joint cartilage injuries and degenerative meniscus lesions as well as pain relief. MATERIAL AND METHODS: The process of obtaining PRP begins by taking 15 ml of blood from the patient with a special system called Arthrex Double Syringe system. The test tube is centrifuged at 4000 rpm for 5 minutes. From the separated plasma, 5-6 ml PRP is taken and prepared for application. PRP is administered intra-articularly. RESULTS: At the Jan Mitrev Clinic in Skopje in 2018, PRP procedures were performed on 126 patients, 56 (44.4%) of whom were male, and 70 (55.6%) were female. The patients were evaluated by the Tegner Lysholm Knee Scoring Scale (TLKSS) before applying 3 doses of PRP for 7 days as well as 3 and 6 months after the application of PRP. The results showed considerable improvement 3 months after the PRP application, and 6 months after the application the results remained approximately identical. CONCLUSION: The application of PRP in the field of medicine is widely applied, and it will continue to be because the understanding of PRP therapy is increasingly refined. This therapy represents a potential and latest method in short-term pain reduction, but additional studies are needed to prove its long-term effectiveness.
School ethos and academic productivity : the Catholic effect

This thesis is a study of the comparative academic effectiveness of Catholic schools in England. It uses a combination of quantitative and qualitative approaches to investigate the hypothesis that, pupils who attend Catholic comprehensive schools will, all things being equal, achieve higher levels of academic attainment in GCSE examinations at the age of sixteen than similar pupils attending other maintained comprehensive schools. The study reviews the published findings of research in this field in England and the United States of America and reports previously unpublished analysis of the results of school inspections made under Section 9 of the Education Act 1992 by OFSTED. There has been very little empirical research into the academic effectiveness of Catholic schools in England. Findings that have been reported have arisen from studies which were focused on other issues and this facet of the results has not been investigated further. In contrast, in the USA there has been a significant quantity of large scale research indicating the academic superiority of schools in the Catholic sector. The research uses a simple form of multi-level modelling as the main analytical tool to compare the performance of pupils (n = 2335) attending eighteen comprehensive schools in a medium sized shire county. In addition, a case study approach is used to compare two different models of Catholic school in the sample to highlight factors which may contribute to their differing levels of academic productivity. The findings partly confirm previous research that has indicated the superiority of Catholic schools in England and extends understanding of the possible causes of that superiority. The study suggests areas for further research and possible applications of the findings for Church authorities and other providers of maintained schools.
A case of Multiple Bilateral Trigger Digits: Injection or Surgery?

Trigger finger is one of the most common problems presenting to hand clinics in the UK [1]. Characterised by catching or locking on extension of the flexed digit it can affect all the digits in the hand [3] with the ring, thumb and middle finger most frequently affected [1, 5] . The incidence of multiple digits being affected is between 20% [5] and 24% [6], with a higher Incidence in Diabetes Mellitus sufferers [5]. The most successful methods used to treat trigger finger are corticosteroid injection and surgical release [1, 11]. We report an extreme case of a patient with eight trigger digits in whom corticosteroid injection had previously failed, review the literature and advocate the use of surgical release as an earlier treatment option in those patients with multiply involved digits.
University of Groningen The impact of leader-member exchange on follower performance in light of the larger social network Regts,

Relationships with leaders do not happen in isolation from the relationships one has with one’s peers. Therefore, we examine the influence of leader‒member exchange on follower job performance in light of the larger social networks in which followers are embedded. Testing multilevel models with data that were gathered using questionnaires from a sample of 240 nurses and 20 supervisors working at four Dutch hospitals revealed that a positive relationship exists between leader‒member exchange and follower job performance when follower workflow network centrality and/or follower friendship network centrality are high but not when they are both low. The results of this study show how the different follower relationships with the supervisor and colleagues intertwine in explaining follower job performance and suggest that the larger network in which followers are embedded within their work teams is important for explaining variations in the results regarding the relationship between leader‒member exchange and follower job performance. Our study indicates that leaders should have an eye for the network position of their followers when developing high quality leader‒ Corresponding author: Gerdien Regt, Faculty of Economics and Business, University of Groningen, PO Box 800, Groningen, 9700AV, Netherlands.

Focus on Mechanisms Linking to Childhood Obesity

Although the prevailing paradigm of obesity remains one of energy intake versus energy expenditure, the abrupt rise in global childhood obesity rates has led researchers to explore alternative contributors. While genetics undoubtedly bestow some obesity risk, the handful of genetic loci associated with obesity in human studies account for <2% of variance in body weight [1], as reviewed in Chapter 13. This observation is not surprising given the abrupt time line of the obesity epidemic. Beyond excess caloric intake and sedentarism, well-studied environmental risk factors for obesity include stress, smoking, sleep patterns, and the microbiome, as reviewed in other chapters in this book. In this chapter, we will discuss mounting evidence implicating developmental exposure to xenobiotic compounds as a hitherto underinvestigated contributor to the global obesity epidemic [2]. This chapter complements Chapter 19, with a focus on understanding the potential mechanisms that might link obesogens to obesity development.
The Effect of Water-Soluble OC “Pepper” Spray on Select Infrared and Electrochemical Breath Alcohol Instruments

ABSTRACT The capability of oleoresin capsicum (OC), or “pepper” incapacitating aerosol sprays, to influence a breath alcohol test was investigated. Eleven drinking and three non-drinking subjects were tested using infrared and fuel cell breath alcohol testing instruments before and after exposure to OC spray. All tests on non-drinking subjects were negative for the presence of alcohol (0.000 g/210 L). For drinking subjects, 9 of 11 (81.8%) subjects had lower BrACs after exposure. Two had higher results (0.004 and 0.001 g/210 L) after exposure, but this was seen as a function of increasing BrAC, and not the influence of the OC aerosol. Following the field testing, a mixture of 9.1% water-soluble OC was placed in a breath alcohol simulator, heated to 34°C, and then introduced to various infrared and fuel cell instruments. The OC mixture did not give a measurable response on any of the instruments (0.000 g/210 L). The oleoresin capsicum used in commercial and law enforcement aerosols does not possess the requisite vapor pressure to produce significant results on breath alcohol analyzers. Recent exposure to OC spray does not appear to influence evidential breath alcohol test results.
Randomized residual‐based error estimators for the proper generalized decomposition approximation of parametrized problems

This article introduces a novel error estimator for the proper generalized decomposition (PGD) approximation of parametrized equations. The estimator is intrinsically random: it builds on concentration inequalities of Gaussian maps and an adjoint problem with random right‐hand side, which we approximate using the PGD. The effectivity of this randomized error estimator can be arbitrarily close to unity with high probability, allowing the estimation of the error with respect to any user‐defined norm as well as the error in some quantity of interest. The performance of the error estimator is demonstrated and compared with some existing error estimators for the PGD for a parametrized time‐harmonic elastodynamics problem and the parametrized equations of linear elasticity with a high‐dimensional parameter space.
Capacity, Bandwidth, and Compositionality in Emergent Language Learning

Many recent works have discussed the propensity, or lack thereof, for emergent languages to exhibit properties of natural languages. A favorite in the literature is learning compositionality. We note that most of those works have focused on communicative bandwidth as being of primary importance. While important, it is not the only contributing factor. In this paper, we investigate the learning biases that affect the efficacy and compositionality of emergent languages. Our foremost contribution is to explore how capacity of a neural network impacts its ability to learn a compositional language. We additionally introduce a set of evaluation metrics with which we analyze the learned languages. Our hypothesis is that there should be a specific range of model capacity and channel bandwidth that induces compositional structure in the resulting language and consequently encourages systematic generalization. While we empirically see evidence for the bottom of this range, we curiously do not find evidence for the top part of the range and believe that this is an open question for the community.
Effect of Soybean lecithin-based Extender on Sperms Motility in the Chilled and Frozen Semen of Nubian bucks

This study was conducted to investigate the effect of different concentrations of soybean lecithin extenders on motility of sperms in the chilled and frozen semen of Nubian bucks. A total of 59 ejaculates were collected from 6 fertile bucks once a week during 9 weeks interval using artificial vagina. After initial evaluation of ejaculates, the semen samples were divided into three equal groups and diluted at 1:5 (semen: extender) using extenders containing 2% egg yolk with tris –citric acid (TCEY, control group, n= 59), 3% soybean lecithin with tris-citric acid (TCSL 3%, n=59) and 4% soybean lecithin with tris-citric acid (TCSL 4%, n=59). The motility rates of spermatozoa after equilibration period at 5oC for one and 4 hours; and after freezing at -196 oC for 30 days were recorded.The results indicated that there were no significant differences in motility rates among the deferent concentrations of TCSL and TCEY at temperature 5 oC for 1 (very good motile: 80-100%) and 4 (good motile: 60-79%) hours. Overall mean of sperm motility rates was lower after cooling for 4 hours than 1 hour. The motility values of post-thawed semen containing TCSL 3% after cryopreservation at -196 oC for 30 days were significantly higher (66.36 ± 10.3 %) than those containing TCSL 4% (60.34 ±11.9 %) (p<0.05). However, there were no significant differences between motility rates of frozen semen diluted with TCSL and TCEY. It could be concluded that soybean lecithin 3% provided the best motility of frozenstored spermatozoa than soybean lecithin 4% and egg yolk.
Critical factors that influence staff retention in an acute perioperative environment

There are a number of factors recognised as significant for nursing staff retention. These include, a lack of organisational care, bullying (commonly referred to as horizontal violence), and high workload acuity. However, there does not appear to be any indication that these factors influence the retention of nurses within the speciality of acute perioperative nursing. A descriptive study using postpositivist methodology and triangulation of methods was designed to answer the question: What are the critical factors that influence staff retention in an acute perioperative environment? Forty-eight (n = 48) perioperative nurses answered a questionnaire in relation to individual needs, provision of nursing care and administration and management. Four (n = 4) nurses subsequently participated in a focus group interview that explored in more depth, the survey data related to the following characteristics: Educational opportunities; Level of workload acuity; Rostering flexibility; Management; Established policies/Quality assurance; Graduate orientation programs and Professional relationships in an acute perioperative setting. Data analysis revealed that > 90% of respondents agreed that these characteristics are important for job satisfaction and influence staff retention in an acute perioperative environment. A sense of belonging appears to be the most important theme that emerged from the qualitative data. Job satisfaction and staff retention are attained when nurses have a sense of belonging in the workplace. To achieve this nurses need to identify barriers, develop their communication and leadership skills and determine the ideal professional practice model. The themes (Figure 5), “Finding time” and increased “sick leave”, in relation to workload acuity are new findings that provide a platform for future research.

Determining factors for Cannabis use among Moroccans Schizophrenic Patients: A cross sectional study

Objective: Cannabis use is considered a major clinical problem associated with a poorer outcome in patients with schizophrenia. The objective of the present study was to assess the prevalence of cannabis us among patients with schizophrenia. The assessment consists in comparing some factors related to substance use in a population of schizophrenic patients between cannabis users and non- Materials and Methods: Four hundred and three participants who were examined prospectively during their hospitalization answered the PANNS scale of schizophrenia, GAF, BIS-10, CDSS, and MARS. The consumption of cannabis was investigated using urine toxicological analysis. Sociodemographic, clinical and therapeutic data were also recorded. Results: The prevalence of cannabis use among schizophrenic inpatients was 49%. Patients with cannabis use were younger (31.7 vs 34.9 years old, p<0.001), more often male (52 vs 20% female, p<0.001), and they presented more often a history of imprisonment (68.8% vs 31.2%, p<0.001). Patients who were users of cannabis had a lower age at onset of the disease than non-users (23.6 vs 24.8 years, p=0.029), and more often with poor medication adherence (p=0.001). Logistic regression revealed that factors associated with cannabis use among schizophrenics were the age, gender, history of imprisonment and poor medication adherence. Conclusion: The study showed that a high prevalence of cannabis use among patients with schizophrenia which was associated with negative overall outcomes. Determining comorbid substance use disorders among schizophrenic patients is crucial as it may contribute to establish a better therapeutic strategy.
Logarithmic corrected $f(R)$ gravitational model and swampland conjectures

In this paper, we use corrected $f(R)$ gravitational model which is polynomial function with a logarithmic term. In that case, we employ the slow-roll condition and obtain the number of cosmological parameter. This help us to verify the swampland conjectures which is guarantee the validation of low - energy quantum field theory. The obtained results shown that the corresponding model is consistent with the swampland conjectures. Also the upper and lower limit of the parameter \textcolor{red}{$n$} are \textcolor{blue}{0.15} and \textcolor{blue}{0.0033}. Finally, by using scalar spectrum index $ n_{s} $ and tensor to scalar ratio $ r $ relations and compared with Planck 2018 empirical data, we obtain the coefficients $\alpha$,$\beta$ and $\gamma$. Also, the corresponding results are creaked by several figures, literature and also plank 2018 data.
Structure and Tensile Strength of Pure Cu after High Pressure Torsion Extrusion

The microstructure and mechanical properties of rod-shaped samples (measuring 11.8 mm in diameter and 35 mm in length) of commercially pure (CP) copper were characterized after they were processed by high pressure torsion extrusion (HPTE). During HPTE, CP copper was subjected to extremely high strains, ranging from 5.2 at central area of the sample to 22.4 at its edge. This high but varying strain across the sample section resulted in HPTE copper displaying a gradient structure, consisting of fine grains in the central area and of ultrafine grains both in the middle-radius area and at the sample edge. A detailed analysis of the tensile characteristics showed that the strength of HPTE copper with its gradient structure is similar to that of copper after severe plastic deformation (SPD) techniques, typically displaying a homogeneous structure. Detailed analysis of the contributions of various strengthening mechanisms to the overall strength of HPTE coper revealed the following: The main contribution comes from Hall–Petch strengthening due to the presence of high and low angle grain boundaries in gradient structure, which act as effective obstacles to dislocation motion. Therefore, both types of boundaries should be taken into account in the Hall–Petch equation. This study on CP copper demonstrated the potential of using the HPTE method for producing high-strength metallic materials in bulk form for industrial use.
Asymptotic analysis of an optimal control problem for a viscous incompressible fluid with Navier slip boundary conditions

We consider an optimal control problem for the Navier–Stokes system with Navier slip boundary conditions. We denote by α the friction coefficient and we analyze the asymptotic behavior of such a problem as α → ∞. More precisely, we prove that if we take an optimal control for each α, then there exists a sequence of optimal controls converging to an optimal control of the same optimal control problem for the Navier–Stokes system with the Dirichlet boundary condition. We also show the convergence of the corresponding direct and adjoint states.
Propagation, cocoon formation, and resultant destabilization of relativistic jets

A cocoon is a by-product of a propagating jet that results from shock heating at the jet head. Herein, considering simultaneous cocoon formation, we study the stability of relativistic jets propagating through the uniform ambient medium. Using a simple analytic argument, we demonstrate that independent from the jet launching condition, the effective inertia of the jet is larger than that of the cocoon when the fully relativistic jet oscillates radially owing to the pressure mismatch between jet and cocoon. In such situations, it is expected that the onset condition for the oscillation-induced Rayleigh–Taylor instability is satisfied at the jet interface, resulting in the destabilization of the relativistic jet during its propagation. We have quantitatively verified and confirmed our prior expectation by performing relativistic hydrodynamic simulations in three dimensions. The possible occurrences of the Richtmyer–Meshkov instability, oscillation-induced centrifugal instability, and Kelvin–Helmholtz instability are also discussed.
Production and evaluation of specialty bread from sprouted mixed-grains

Specialty bread was made from sprouted mixed-grains using adaptable technology. The grains were sprouted at atmospheric conditions (30°C, 75% RH) over a period of 6, 12, 18 and 24 h. Paste obtained from the sprouts was mixed at different ratio together with other ingredients to obtain five bread samples. Nutritional, functional and sensory properties of the resulting loaves were carried out using standard analytical methods. Conventional bread served as a control. Sprouting improved (p<0.05) the nutritional and functional properties of mixed-grain bread. Dietary fiber was 5.36 and 20.91 g/100 g -1 , acidity 1.23 and 5.73% and protein energy 29.13 and 108.72 KJg -1 for control and 24 h sprouted mixedgrain bread, respectively. The developed bread may qualify as a health food judging from the data generated in this research. The breads were equally acceptable to the panel judges. Twenty-four hour sprouting is considered best for production of mixed-grain bread.
