INTRODUCTION. Despite the widespread use of methods for thermoobliteration of varicose veins, there are no standards for prescribing solutions for tumescent anesthesia when performing these operations. Existing prescriptions can be difficult, both in terms of finding the necessary components in a certain concentration, and in terms of correct dilution of the components in saline. AIM OF STUDY. To determine the reasonability of using complex medicinal prescription solutions for tumescent anesthesia when performing endovenous laser obliteration of varicose veins of the lower extremities. MATERIAL AND METHODS. The prospective study included 64 patients who underwent endovenous laser obliteration of the great or small saphenous vein. The operations were performed in accordance with the standard protocol on a device with a wavelength of 1,940 nm and radiation power from 5.0 to 6.0 W. Tumescent anesthesia was created using an automatic infiltration pump using 21 G needles with a length of 120 mm. Group I included patients (n = 34) who were anesthetized with a 0.1 % lidocaine solution at room temperature. Group II included patients (n = 30), for whom the anesthesia solution was prepared according to Klein’s standard prescription for tumescent anesthesia. The distribution of patients into groups was carried out using random sampling. Evaluation criteria: the presence or absence of complaints of pain during surgery and the level of pain assessed using a visual analogue scale. RESULTS. The groups did not differ statistically significantly in terms of main clinical and demographic indicators (p < 0.05). Complaints of pain or burning during surgery were made by 2 patients (5.9 %) in group I and 5 patients (16.7 %) in group II (p = 0.0023). The average pain value according to the visual analogue scale in group I was 0.75 cm [0.30; 1.44], in group II – 1.85 cm [0.85; 2.72], p = 0.0017, while in group I the maximum number of patients — 24 (70.6%) were distributed in the range of 0–1 cm, in group II the maximum number of patients, 17 (56.7 %) were distributed in the range of 1.5–3 cm according to a visual analogue scale. CONCLUSIONS. When using a simple 0.1 % lidocaine solution for tumescent anesthesia, a significantly lower average pain value according to VAS was obtained in comparison with the group of patients who used the standard D. Klein solution (0.75 cm and 1.85 cm, respectively, p = 0. 0017). Also, for the study group, a significantly lower frequency of perioperative complaints and complaints of severe pain was obtained (p < 0.01). The use of complex prescriptions of solutions for tumescent anesthesia when performing endovenous laser obliteration of varicose veins is impractical. The use of a simple 0.1 % lidocaine solution at room temperature, while following the surgical protocol, provides comfortable anesthesia.

AIM OF THE STUDY. To investigate the clinical and functional outcomes of autosplenotransplantation in cases of spleen injuries, and to establish its effectiveness in clinical practice. MATERIAL AND METHODS. Using the databases “e-library” and “PubMed”, a thorough review of national and international literature on autosplenotransplantation in patients with traumatic splenic injury was performed. RESULTS. This study analyzes literature sources to describe the technical aspects of autosplenotransplantation. The immediate outcomes of this operation show a low incidence of postoperative complications and good graft survival. In addition, this study presents the indications and contraindications of autosplenotransplantation. Comparing autosplenotransplantation to splenectomy, functional results indicate the best indices of humoral and cellular immunity and hemocoagulation. In the published literature, the functional activity indices of the transplant were comparable to those of healthy individuals with the functioning spleen. However, the studies yielding these results were conducted on small patient samples, limiting the reliability of the conclusions drawn. CONCLUSION. Autosplenotransplantation appears to be the only viable option for preserving the function of the lost spleen in patients with traumatic splenic injury who, for various reasons, cannot receive organ-preserving treatment. Large randomized studies are needed to assess functional results of the operation and, particularly, the immunological function of the transplant.

AIM OF STUDY. To describe a rare clinical case of surgical treatment of chronic recurrent dislocation of the forearm bones using the method of circular plastic surgery of the elbow joint ligaments. MATERIAL AND METHODS. In the conditions of the Department of Traumatology and Orthopedics on the basis of the Department of Traumatology and Orthopedics of the Federal State Autonomous Educational Institution of Higher Education “Russian Peoples’ Friendship University” in the V. M. Buyanov City Clinical Hospital of the Moscow Health Department, a comprehensive diagnosis and treatment of a 38-year-old patient with recurrent dislocation of the forearm bones was carried out. Clinical and radiological examinations including computed tomography and magnetic resonance imaging of the elbow joint were performed to verify the diagnosis. After a diagnosis of chronic posterior instability of the elbow joint was established, simultaneous plastic surgery of the medial and lateral ulnar collateral ligaments was performed using a single-loop circular autograft from the peroneus longus tendon. RESULTS. At a follow-up period of 12 months, a successful clinical result of surgical treatment with restoration of stability and function of the elbow joint was observed. Pain syndrome on the VAS scale decreased to 1 cm (before surgery 0 cm) with physical activity. The amplitude of active movements in the elbow joint after surgery was: flexion 140° (before surgery 135°), extension 5° (before surgery 5°), pronation-supination 150° (before surgery 160°). After surgery: QuickDASH score 26 (before surgery 44 points), OES score 72 (before surgery 45), MEPS score 85 (before surgery 55). MEPS was score 55, OES was score 45, QuickDASH was 44 points, QuickDASH (work section) was score 75. CONCLUSION. The method of tendon circular plasty of the elbow joint is an effective method of surgical treatment of multidirectional recurrent instability of the elbow joint, helps restore stability and function of the joint and does not lead to limitation of movements.

Published: September 2024

Performance measurement regarding collaborative supply chain of fresh produces such as fruit and vegetables that combines vertical and horizontal collaboration structures is rarely found in the literature. Performance metrics in this lateral collaborative structure are useful for tracking and measuring the achievement of more comprehensive business goals that are not found in only vertical or horizontal structures. This research aims to explore and propose the best model for collaborative performance system (CPS) in the fresh produce supply chain (FPSC) and success factors in CPS implementation, including CPS metrics and matching collaborative individual performance (CIP) and supply chain performance (SCP). Papers from the last seventeen years including journal papers, working papers and conferences were selected in three steps. From 175 articles found in the first step, 63 articles matched the topic. In the third step, 48 articles were selected as important topics of discussion focused on the field of fresh products, with three classifications of collaboration structures and identifying CIP and SCP metrics which were then analyzed. The results of this review provide good opportunity as reference material for further research, through a comprehensive analytical description complete with a conceptual model presented to complete the gaps in this field. Keywords: Collaborative Performance System, Lateral Model, Performance Metrics, Rural Farmers, Supply Chain.

The purpose of this study is to find out the strengthening of the President's authority and identify polemics that have arisen related to the dissolution of ministries based on a review of Law Number 39, 2008. This study used a normative qualitative approach. The research was conducted at ministry and official agencies, as well as several activists at state studies institutions in the provinces of South-Sulawesi and West-Sulawesi. This research applies legal material collection techniques through documentation or literature studies and interview techniques. The results of the analysis show that in the process of forming a cabinet, good cooperation between the two institutions is needed to reach agreement and consensus. Intense communication and dialogue between the president as the head of the executive and parliament as the legislature helped to reach a consensus on the composition of the cabinet which was considered effective and capable of obtaining sufficient political support. The polemic that occurred was due to the lack of transparency in public participation, as well as collaboration between government agencies in the preparation and ratification of laws and regulations.

Abstract
Methoxypolyethylene glycol 1900 and α-bromoisobutanoyl bromide were utilized for alcoholysis reaction to obtain a macromolecular initiator. Then, a simple amphiphilic diblockpolymer (mPEG-PDMAEMA) based on the initiator and dimethylaminoethyl methacrylate was synthesized through the atomic transfer radical polymerization (ATRP) method. The structures of the initiator and diblock polymer were accurately characterized using infrared spectrum and proton nuclear magnetic resonance spectroscopy (1H NMR). Cryo-transmission electron microscopy revealed the self-assembly of mPEG-PDMAEMA into vesicle-like structures in water. Upon injection of CO2 into the solution, the tertiary amine structure within PDMAEMA underwent protonation, resulting in the mPEG-PDMAEMA adopting a hydrophilic structure. Consequently, the vesicles dissociated and dispersed, forming a network-like structure in water. The protonation phenomenon was confirmed by 1H NMR, as evidenced by the shifting of alkyl hydrogen atoms near nitrogen atoms toward downfield positions.

Abstract
The preparation of composite metal oxide to attain high efficiency in removing phenol from wastewater has a great concern. In the present study, the focus would be on adopting antimony-tin oxide coating onto graphite substrates instead of titanium; besides the effect of SbCl3 concentration on the SnO2-Sb2O3 composite would be examined. The performance of this composite electrode as the working electrode in the removal of phenol by sonoelectrochemical oxidation will be studied. The antimony-tin dioxide composite electrode was prepared by cathodic deposition with SnCl2 . 2H2O solution in a mixture of HNO3 and NaNO3, with different concentrations of SbCl3. The SnO2-Sb2O3 deposit layer’s structure and morphology were examined and the 4 g/l SbCl3 gave the more crystallized with nanoscale electrodeposition. The highest removal of phenol was 100% at a temperature of 30 oC, with a current density (CD) of 25 mA/cm2.

Introdução: No Brasil, a criação do SUS visou ampliar o acesso aos serviços, com a APS sendo o primeiro contato da população. A PNAB, desde 2006, estabelece diretrizes para a ESF, mas mudanças nas edições de 2011 e 2017 podem afetar a cobertura e qualidade do atendimento. Objetivo: Este estudo visa mapear as repercussões da PNAB nas UAPS no Brasil, identificando os desafios enfrentados pelas equipes de saúde devido às mudanças no contexto da APS. Método: Foram seguidos os métodos do Joanna Briggs Institute e PRISMA-ScR, com estudos primários, secundários, editoriais e opiniões de especialistas desde 2006, utilizando bases de dados relevantes e análise independente com Rayyan. Resultados e Discussão: Após uma triagem inicial de 1.796 artigos, 21 foram incluídos visando mapear as repercussões da PNAB nas UAPS. A atualização da PNAB permitiu a divisão da carga horária semanal para até três profissionais da mesma área, levando a uma fragmentação do trabalho e diminuição dos vínculos e reduziu o número de ACS, causando sobrecarga na unidade e falta de acompanhamento dos pacientes. Conclusão: A Política Nacional de Atenção Básica (PNAB) passou por reformulações entre 2006 e 2017, afetando a composição das equipes de saúde da família e suas cargas horárias. O financiamento da atenção básica também foi alterado, indicando uma tendência de mercantilização dos serviços de saúde.

Published: September 2024

The performance of teachers in Kenya, measured from their learners’ performance in KCSE, has remained wanting for a long time. In order to address this challenge, the teachers’ employer, the Teachers Service Commission (TSC), adopted initiatives to manage the performance of duties of her employees. However, these measures seem to have no positive impact. This study sought to establish the influence of performance management initiatives on the performance of public secondary school teachers in Kenya. It sought to establish the influence of internal quality assurance on the performance of public secondary school teachers in Kenya.
The study utilized a mixed-method research design. The study population comprised 122310 public secondary school teachers employed by the Teachers Service Commission and 295 Sub County TSC Directors who are the immediate supervisors of the teachers. Multistage sampling was used to cluster the Country into eight geographical regions administered by TSC regional directors as Primary Sampling Units (PSUs). Each region was again clustered into counties as Secondary Sampling Units (SSUs), and then each county was clustered into sub-counties as Ultimate Sampling Units (USUs), where schools were stratified into National, Extra County, County and Sub County schools where teachers were purposefully selected according to how long they had taught students up to form four per subject and a sub-county director from each sub-county selected. Slovin’s formula was used to select 399 respondents from teachers and TSC sub-county directors. Self-administered questionnaires were used to collect primary data from teachers, and interview schedules were done for principals and sub-county directors. Collected data was analyzed using SPSS, and descriptive, inferential, and regression statistical techniques were used. Frequencies, Means and Standard Deviations presented the descriptive data, while inferential statistical tests were presented using Pearson Product Moment Correlational Coefficient and regression analyses.
Null hypotheses were tested using the Pearson Product Moment Correlational Coefficient. The hypotheses’ results indicated that there was a weak significant relationship between internal quality assurance and the performance of public secondary school teachers in Kenya. It was recommended that the TSC should sponsor field officers to monitor and strengthen quality assurance in schools.
Reversible sulcal fluid-attenuated inversion recovery hyperintensity after combined bypass surgery for moyamoya disease – A “crevasse” sign
Authors: Kashiwazaki Daina , Yamamoto Shusuke , Hori Emiko , Akioka Naoki , Noguchi Kyo , Kuroda Satoshi 
Published: September 2024

Background:
Transient fluid-attenuated inversion recovery (FLAIR) hyperintensity is often observed on the operated brain surface after direct or combined bypass surgery for moyamoya disease, but its pathophysiology and clinical significance are still obscure. This study was aimed to clarify the underlying mechanism and clinical significance.

Methods:
This prospective study included 106 hemispheres of 61 patients with moyamoya disease and analyzed their radiological findings before and after combined bypass surgery. This study also included 11 patients who underwent superficial temporal artery to middle cerebral artery anastomosis for occlusive carotid artery diseases as the controls. Magnetic resonance imaging examination was serially repeated, and cerebral blood flow was measured before and after surgery. Signal intensity ratio (SIR) in the cortical sulci and cortex to the adjacent white matter on FLAIR images was calculated, and the postoperative SIR changes were semi-quantitatively evaluated to assess the temporal profile of postoperative FLAIR hyperintensity.

Results:
Postoperative FLAIR hyperintensity occurred within the cortical sulci on the operated hemispheres in all moyamoya patients but not in patients with occlusive carotid artery diseases. SIR values started to increase immediately after surgery, peaked at about 4-fold at 4–13 days post-surgery, then declined, and recovered to baseline values over 28 days or later. The magnitude of this phenomenon was proportional to the severity of cerebral ischemia but not to postoperative hyperperfusion.

Conclusion:
Reversible sulcal FLAIR hyperintensity specifically occurs in the operated hemispheres after direct bypass surgery for moyamoya disease. This “crevasse sign” may represent the mixture of the extensive leakage of oxygen and proteins from the pial arteries into the CSF.
