The influence of marketing communication on students' decisions to enrol at Technical Vocational Education and Training colleges in KwaZulu-Natal
Authors:   , Vezi Freedom Clement
Published: July 2022

Marketing higher education is a growing field of expertise in many developing countries. However, little research has been done on marketing Technical Vocational Education and Training (TVET) Colleges in South Africa. Evidence suggests that it may suffer from a lack of expertise to provide direction to the practical aspects of marketing TVET Colleges. Most of the marketing practices of Higher Education are underdeveloped and lack a strategic focus when it comes to Technical Vocational Education and Training (TVET). For TVET Colleges marketing communication plays an important role in students’ recruitment. The aim of this study is to analyse the influence of marketing communication towards students’ decisions to enrol at Technical Vocational Education and Training Colleges (TVET). The objectives of this study is to determine factors that influence students in the selection of a TVET College. Additionally, the study strives to identify students’ perceptions towards TEVT Colleges, and investigate marketing communication practices that contributes toward improving students’ perceptions at TVET. The study was conducted in KwaZulu-Natal where the targeted TVET colleges are based. This is a quantitative, descriptive, and cross-sectional study conducted among a sample of 400 TVET College students. Data was analyzed using SPSS. The results of this study reveal the need for marketing communication in TVET Colleges to be addressed urgently in order to improve public perception and enrolment rates at TVET Colleges. Both students and TVET Colleges will benefit from the study because marketing and communication as a source of information will assist when selecting a college of choice. In addition, this will also assist TVET Colleges in the selection of appropriate marketing communication media to enable proper allocation of marketing budget and resources The findings of this study will then act as guidelines to determine a more appropriate marketing communication strategy to improve the public perceptions of TVET Colleges to make TVET Colleges a students’ first choice.

Published: July 2022

Different social classes of people in South Africa are divided, digitally. This phenomenon manifests as a disparity of information in ICT (Information and Communication Technologies), which is a matter of concern, as the use of ICT is acknowledged to greatly influence the world today, more specifically so in rural areas. An investigation to determine which factors affect rural communities’ access to information, as well as progress levels that can be realised in the support means employed by people resident in rural areas, through introducing ICT’s in their day-to-day living, thus addresses the purported ‘digital divide’. The study’s population was drawn from the Dibate Village community, located in Mmabatho in Mafikeng, South Africa. Recommendations from the findings, point out how ICT facilities can be utilised in the development of rural communities, not just socially but also economically. As main objective, the study evaluates and examines the use of ICT facilities for commercial activities, in uplifting the rural community in the area of Dibate Village. This study is of value to governmental and non-governmental organisations where improving both socio-economic development and service delivery is concerned, in South Africa’s rural areas.
The quality interface between primary and secondary phase mathematics at public schools in Mafukuzela Gandhi Circuit in KwaZulu-Natal
Authors:   , Moodley Savathrie
Published: July 2022

Quality has emerged as a necessity in education as we are faced with increasing competition and a demand for better quality of life. There is an enormous gap in South Africa’s education system; 60% of South Africa’s children do not reach the final matriculation school year. Many Grade 12 learners, despite being taught Mathematics, remain effectively mathematically illiterates. The ability to provide quality education is more than ever essential and there is at present a consensus for fundamental reforms in our education sector, with emphasis on Quality. The result of quality education is not only about achieving academic excellence but the total development of the learner. If education does not cater for the future needs and challenges of the new millennium then it is ineffective for the new generation. Low scores in Mathematics are a major concern as learners are not able to meet the challenges in secondary schools to pursue careers in Mathematics. South Africa was placed last out of 41 countries worldwide in terms of Mathematics performance in the Third International Mathematics and Science Study (TIMSS). The World Economic Forum has placed South Africa last amongst 62 countries on the quality of Mathematics and Science Education in their annual report in 2012. Apartheid in South Africa was a complex period that paved the way for the new education dispensation. A paradigm shift was thus imperative and challenging to a democratic South Africa. It is more than two decades into the 21st century and into a democratic South Africa. The effects of apartheid are visible in many areas, more so in education. This study is underpinned by the transformation agenda attached to curriculum policy reform in South Africa. There is an interface in respect of policy construction and Skills, knowledge, attitudes and values (SKAV) constitution from the Department of Education to primary and to secondary schools. The implementation of various curriculum reforms led to a decline in the pass rate of learners in the National Senior Certificate examinations and in the Annual National Assessment. Some of the serious problems articulated by teachers were inadequate subject training in Mathematics, lack of communication, job dissatisfaction and the demanding administrative workload. It is envisaged that the findings of this study will make recommendations for SKAV development in teaching and learning of Mathematics in primary and secondary schools. In this regard, a model to improve quality in Mathematics education was proposed. The ability of education to meet the needs of the future both at individual and societal level is one of the critical elements of quality education.

Extending Ensemble Kalman Filter Algorithms to Assimilate Observations with an Unknown Time Offset
Authors: Gorokhovsky Elia , Anderson Jeffrey L.
Published: July 2022

Abstract. Data assimilation (DA), the statistical combination of computer models with measurements, is applied in a variety of scientific fields involving forecasting of dynamical systems, most prominently in atmospheric and ocean sciences. The existence of misreported or unknown observation times (time error) poses a unique and interesting problem for DA. Mapping observations to incorrect times causes bias in the prior state and affects assimilation. Algorithms that can improve the performance of ensemble Kalman filter DA in the presence of observing time error are described. Algorithms that can estimate the distribution of time error are also developed. These algorithms are then combined to produce extensions to ensemble Kalman filters that can both estimate and correct for observation time errors. A low-order dynamical system is used to evaluate the performance of these methods for a range of magnitudes of observation time error. The most successful algorithms must explicitly account for the nonlinearity in the evolution of the prediction model.
An adapted deep convolutional RNN model for spatio-temporal prediction of wind speed extremes in the short-to-medium range for wind energy applications

Published: July 2022

Abstract. The amount of wind farms and wind power production in Europe, both on- and off-shore, has increased rapidly in the past years. To ensure grid stability, on-time (re)scheduling of maintenance tasks and mitigate fees in energy trading, accurate predictions of wind speed and wind power are needed. It has become particularly important to improve wind speed predictions in the short range of one to six hours as wind speed variability in this range has been found to pose the largest operational challenges. Furthermore, accurate predictions of extreme wind events are of high importance to wind farm operators as timely knowledge of these can both prevent damages and offer economic preparedness. In this work we propose a deep convolutional recurrent neural network (RNN) based regression model, for the spatio-temporal prediction of extreme wind speed events over Europe in the short-to-medium range (12 hour lead-time in one hour intervals). This is achieved by training a multi-layered convolutional long short-term memory (ConvLSTM) network with so-called imbalanced regression loss. To this end we investigate three different loss functions: the inversely weighted mean absolute error (W-MAE) loss, the inversely weighted mean squared error (W-MSE) loss and the squared error-relevance area (SERA) loss. We investigate forecast performance for various high-threshold extreme events and for various numbers of network layers, and compare the imbalanced regression loss functions to the commonly used mean squared error (MSE) and mean absolute error (MAE) loss. The results indicate superior performance of an ensemble of networks trained with either W-MAE, W-MSE or SERA loss, showing substantial improvements on high intensity extreme events. We conclude that the ConvLSTM trained with imbalanced regression loss provides an effective way to adapt deep learning to the task of imbalanced spatio-temporal regression and its application to the forecasting of extreme wind events in the short-to-medium range, and may be best utilised as an ensemble. This work was performed as a part of the MEDEA project, which is funded by the Austrian Climate Research Program to further research on renewable energy and meteorologically induced extreme events.
An approach to evaluate the dominant river biogeomorphic succession phase at the reach-scale 
Authors: Han Meiqin , Brierley Gary , Pan Baotian , Geng Haopeng , Shi Yan
Published: July 2022

The Fluvial Biogeomorphic Succession phase model (FBS model) differentiates Geomorphic (G), Pioneer (P), Biogeomorphic (B) and Ecological (E) phases of hydro-geophysical-biological interactions in river systems. To date, quantitative applications of this model have been restricted to field surveys of vegetation composition analysis at the patch-scale. Here we develop a biogeomorphic landform mapping approach to determine the dominant biogeomorphic succession phase at the reach scale. We categorize river morphology into four biogeomorphic landform types (G-, P-, B- and E-landforms) that have particular geomorphic, substrate and vegetation cover characteristics. Ratios of these landforms are used to calculate the dominant succession phase in a given reach. A test of this method conducted for two contrasting anabranching reaches of the Upper Yellow River indicates that landform ratios provide an efficient and reliable approach to assess river biogeomorphic succession phase. The approach can be adapted to support systematic cross-scalar analyses across the range of river environments.

The OBS noise due to deep ocean currents

Published: July 2022

Abstract. Ocean bottom seismometers (OBS) are usually deployed for seismological investigations but these objectives are impaired by noise resulting from ocean environment. We split the OBS recorded seismic noise into three domains, short-period, microseisms and long-period, also known as tilt-noise. We show that the first and third domains are controlled by bottom currents but these are not always a function of the tidal forcing. Instead we suggest that the ocean bottom has a flow regime resulting from two possible contributions, the permanent low frequency bottom current and the tidal current. The recorded noise displays the balance between these two currents along the full tidal cycle, between neap and spring tides. In the short-period noise band the ocean current generates harmonic tremors that corrupt the dataset records. We show that, in the analyzed cases, the harmonic tremors result from the interaction between the ocean current and mechanical elements of the OBS that are not essential for sea bottom recording and thus have no geological origin. The data from a new Broadband OBS type, designed and built at Instituto Dom Luiz (University of Lisbon)/CEIIA, hiding no essential components from current flow, shows how utmost of the harmonic noise can be eliminated.
Fault slip potential induced by fluid injection in the Matouying enhanced geothermal system (EGS) field, Tangshan seismic region, North China

Published: July 2022

Abstract. The Tangshan region is one of the most seismically active areas in
the North China, and the 1976 M 7.8 earthquake occurred on 28 July near
the Tangshan fault zone. The Matouying enhanced geothermal system (EGS)
field is located ∼90 km away from the city of Tangshan. Since late 2020, preliminary hydraulic stimulation tests have been conducted at
depths of ∼3965–4000 m. Fluid injection into geothermal reservoir facilitates a heat exchanger system. However, fluid injection may also induce earthquakes. In anticipation of the EGS operation at the Matouying uplift, it is essential to assess how the fault slip potential of the nearby active and quiescent faults will change in the presence of fluid injection. In this study, we first characterize the ambient stress field in the Tangshan region by performing stress tensor inversions using 98 focal-mechanism data (ML≥2.5). Then, we estimate the principal stress magnitudes near the Matouying EGS field by analyzing in situ stress measurements at shallow depths (∼600–1000 m). According to these data, we perform a quantitative risk assessment using the Mohr–Coulomb framework in order to evaluate how the main active faults might respond to hypothetical injected-related pore pressure increases due to the upcoming EGS production. Our results mainly show that most earthquakes in the Tangshan seismic region have occurred on the faults that have relatively high fault slip potential in the present ambient stress field. At well distances of less than 15 km, the probabilistic fault slip potential on most of the boundary faults increases with continuing fluid injection over time, especially on the faults with well distances of ∼6–10 km. The probabilistic fault slip potential (fsp) increases linearly with the fluid injection rate. However, the fsp values decrease exponentially with increased unit permeability. The case study of the Matouying EGS field has important implications for deep geothermal exploitation in China, especially for Gonghe EGS (in Qinghai Province) and Xiong'an New Area (in Hebei Province) geothermal reservoirs that are close to the Quaternary active faults. Ongoing injection operations in the regions should be conducted with these understandings in mind.

Published: July 2022

ABSTRACT. The incorporation of Service-Learning Projects (SLPs) into the medical school curriculum is an effective way for students to adopt the leadership skills necessary to apply their traditional education on social determinants of health into targeted action. For our SLP, our team of second-year medical students organized an after-school science program to address the concerns of academically at-risk K-5th grade students at a local Non-Profit Organization (NPO). The goal was to increase interest in Science, Technology, Engineering, and Mathematic (STEM) subjects and careers. Our weekly lesson plans always utilized experimental learning models in an effort to foster engagement. Throughout the duration of the project, student participation grew to three-fold of the initial cohort. Through this SLP, we identified a disparity within our local community and developed a targeted solution to address this issue. We honed our skills not traditionally covered in a medical school curriculum, including program planning, fundraising, marketing, etc., and feel more capable taking on more significant leadership roles in the future. Additionally, our specific SLP provided us with an invaluable lesson in fostering communication skills that will benefit patient education.
Can the Relationship Between Problem Gambling and Class Attendance of College Students Be Explained by Alcohol and Drug Use? A Brief Report
Authors: Kurilla Adam , Hawley Carolyn E. , Cathers Lauretta , Iwanaga Kanako
Published: July 2022

Engagement in addictive behaviors such as social casino gaming (SCG), gambling, and alcohol and drug use has a significant negative impact on physical and mental health and classroom attendance, leading to an academic failure. This study aimed to (a) determine the prevalence of SCG, gambling, alcohol use, and drug use in a sample of 390 college students; (b) examine the relationship among SCG, gambling problems, alcohol and drug use, and class attendance problem using Pearson correlations and point-biserial correlations; and (c) evaluate the extent to which alcohol and drug use can explain the relationship between gambling problems and class attendance problem using parallel mediation analysis. SCG was found to be related to gambling problem and drug use problem. Gambling was found to be a predictor of alcohol and drug use problems. However, interestingly, SCG and gambling problems were not directly related to class attendance problem. The parallel mediation analysis confirmed students at risk for gambling problems were more likely to have alcohol use problems, and alcohol use problems led to poor class attendance. Rehabilitation services providers who work with college students should be mindful of the relationship among the addictive behaviors and class attendance problem and tailor rehabilitation services interventions.

Influence of the essential oil of thyme and the introduction of yeast mushrooms from the genus sacharomycetes on the organism of the rainbow trout
Authors: Popova O. S.
Published: July 2022

The aim of this study was to investigate the combined effects of thyme essential oil and Saccharomycetes on blood counts and body productivity in rainbow trout. The fishery complex demonstrates positive dynamics in all key economic indicators. The use of feed additives in a complete fish diet is one such practical solution that not only improves nutritional efficiency, but also helps to reduce stress and control diseases by strengthening the immune system of fish. The study was carried out in the fish farm of the Leningrad region, on rainbow trout. 3 groups were taken, 5 in each group. The control group received only the main diet, only Saccharomycetes were introduced to the diet of group 2, and thyme essential oil was added to the main diet of group 3 in addition to Saccharomycetes. The mixture was administered at a dose of 2% of the norm was the essential oil of thyme, and 0.1% of saccharomycetes. Physico-chemical indicators of water, including temperature, were at the same level in all groups, within the physiological norm. The experiment lasted 30 days; at the end of the experiment, blood was taken to study blood parameters. Statistical analysis was carried out using STATISTICA 6 software.

The present study showed that the combination of Saccharomycetes and thyme essential oil promotes the full development of fish and the efficient use of feed. Can theoretically successfully increase growth rates, survival rates, and digestive enzymes in farmed rainbow trout. Also, their inclusion in the diet can be useful for enhancing immune parameters and antioxidant responses and, therefore, can be included in the diet of this fish species as a safe feed additive.

Published: July 2022

Fasting (short or long term) is an important factor influencing physiological changes in immunity, survival and growth. During starvation, the most important processes in fish are supported by the accumulated nutrients. Structural components of the gastrointestinal tract and associated organs respond differently to food deprivation. We found that fasting had a profound effect on intestinal histology, which ultimately led to malabsorption and transport. In particular, there was hyperplasia of goblet cells, a decrease in the height of prismatic epitheliocytes with degeneration of microvilli on their apical surface. In some situations, fusion of the intestinal folds was detected. It should be noted that this issue has been poorly studied in the available domestic literature.

Published: July 2022

Monitoring of the incidence of cats and dogs with infectious diseases, as well as the development of recommendations to owners to prevent infection of their pets with these diseases, are important elements of ensuring the epizootic well-being of cities. It was found that cats are more susceptible to infection with infectious diseases, for 2019-2021, the Veterinarian Advisory Center annually received 111 cats and 17 dogs with infectious pathology on average. The most frequently reported pathologies are calico- and herpesvirus infections of cats. There is no clearly predominant infectious pathology in dogs. A single dynamics of the incidence of infectious diseases in animals by year has not been revealed. When analyzing treatment regimens and preventive measures for infectious diseases of cats and dogs, we come to the conclusion that if there are effective means of complex therapy, animal owners need to focus their attention on their specific prevention with the use of Russian vaccines.

Published: July 2022

The paper presents the results of a morphological study of the blood of healthy dogs and dogs with acute enterocolitis. Also, a physical examination was carried out on sick animals. On external examination, it was noted that the dogs with enterocolitis were mostly apathetic, some took a forced lying position. Of the studied 10 sick dogs, 7 had satisfactory fatness, 3 dogs had unsatisfactory fatness. In a significant part of dogs with enterocolitis, the coat is matte, the coat is ruffled and poorly retained in the hair follicles, the skin turgor is reduced. The color of the visible mucous membranes in dogs with enterocolitis varies from pale pink to grayish with an icteric tinge. The main revealed pathological changes in the study of the digestive system of dogs with enterocolitis were: increased defecation, diarrhea, feces of a mushy consistency with mucus admixtures, sometimes with blood, oligophagia or anorexia, abdominal wall tension, intestinal soreness with penetrating palpation, increased peristalsis with mediocre auscultation. In animals with signs of enterocolitis, erythrocytosis, leukocytosis and hyperchromemia were noted. At the same time, the hematocrit index was 20.9% higher in sick dogs, compared with this indicator in healthy animals. When analyzing the leukogram of animals of both groups, no significant changes were found.
Quality management in bioequivalence assessment: problems and prospects
Authors: Ponamarev V. S.
Published: July 2022

One of the main problems of modern drug production is the assessment of bioequivalence during the life cycle of the product at the stage of preliminary approval (the stage of clinical trials) and at the stage after approval.

Getting a biowaiver is very important for pharmaceutical companies because of the significant savings in resources and time. However, if this is not done with scientific justification, safety and efficacy may be affected due to false positive decisions. Often differences in bioavailability are not found in pharmaceutical practice and hence are rarely reported.

A search of original studies in the scientific databases of PubMed, Elsevier Science (Scopus) and Clarivate Analytics (Web of Science) was carried out to determine the distinguishing features of the biowaiver methodology, followed by analysis of the data obtained.

In general, pharmaceutical development should relate in vitro dissolution to in vivo product efficacy. Under certain conditions, the results of a comparative bioavailability or clinical study can be extrapolated to all generic drugs. Biowaiver considerations include drug pharmacokinetics, dosage form type, manufacturing processes, and formulation proportionality. The article summarizes the unresolved issues associated with biowaiver based on the Biopharmaceutical Classification System (BCS), but also discusses the positive aspects of the prospect of further uses of the biowaiver procedure.

Unresolved issues that have arisen in the analysis of examples of false negative and false positive results described in the literature require further adjustment of regulatory requirements. Possible ways to solve these problems are the use of modeling and simulation, as well as the improvement of in vitro biorelevant tests, which are able to distinguish dosage forms with unequal in vivo efficiency, which potentially effectively allows the use of the biowaiver procedure.

Objective: To accurately identify the patients with unresectable pancreatic cancer through the use of computed tomography imaging.

Material & Methods: This descriptive case series was conducted at Kuwait Teaching Hospital from July 2019 to June 2020. A total of 52 patients were evaluated with ages ranging from 11-90 years comprising 24 males and 28 females. CT scan abdomen with the pancreatic protocol was done on 16 slice Toshiba CT scanner in the Radiology department of Kuwait Teaching Hospital. Images were evaluated in axial, coronal and sagittal planes following pancreatic protocol. Data like patient age, gender, tumor location, size, venous and arterial involvement, lymph nodal and adjacent visceral involvement were collected and subjected to statistical analysis.

Results: Out of a total of 52 patients, pancreatic carcinoma was most prevalent in the head region which was observed in 35(67.3%) patients. The next common site was the uncinate process followed by the body and then the tail. In 57.7% the size of primary malignancy was more than 2 cm and in 42.3% of the patients, it was less than 2 cm. Superior Mesenteric Vein (SMV) was involved in pancreatic carcinoma in 7.7%, Inferior Vena Cava (IVC) in 3.8% and Portal Vein (PV) in 11.5% of the cases. The Celiac Artery was involved by the pancreatic tumor in 11.5% and Superior Mesenteric Artery (SMA) in 23.1% of the cases. Lymph nodal involvement was observed in 42.3% of the cases and adjacent visceral involvement was noted in 34.6% of the cases.

Conclusion: Pancreatic carcinoma was identified as surgically unresectable by CT scans in the majority of patients because of locally advanced disease having a size more than 2 cm, and with vascular, lymph nodal and adjacent visceral involvement.

Incisional hernias present as ventral hernias but very rarely they may present as a recurrent hernia in the flank. We present the case of a 67-year-old male with past surgical history significant for open repair of recurrent ventral incisional hernia, previous component separation and surgical removal of infected mesh two years back; now presenting with a left lateral flank mass later confirmed as left lateral incisional hernia upon CT scan. The patient was planned for a laparoscopic incisional hernia repair with 20*20 cm Ventralight mesh. At 3 months postoperative follow-up visit the patient was doing well and had returned to normal activity. There was no evidence of any recurrence.

Introduction: Otitis media, also known as middle ear infection, refers to any inflammation of the middle ear. It may be attributable to bacteria like Streptococcus pneumoniae and Hemophilus influenzae (most commonly involved), though viruses can also cause middle ear infection. It affects the pediatric group during the first three years of life, with 80% youngsters having had one otitis media episode at the minimum by age three years, 50% having had at least three episodes, while a smaller number experience their first episode after age three years. This phenomenon has also been linked to an increased presence of Streptococcus mutans which in turn raises the risk of acquiring dental caries.

Objective: To determine whether an association exists between middle ear infection and the high occurrence of Streptococcus mutans that ultimately leads to dental caries in children and causes poor oral hygiene problems.

Materials & Methods: A comprehensive and well-organized search of published articles was conducted in February 2022. The investigation was conducted using the Reporting Items for Systematic Reviews. Articles that fulfilled the predefined inclusion and exclusion criteria were appraised with respect to the key objectives of the review.

Results: Based on the findings of the studies highlighted in this systematic review, not only was there a positive correlation between middle ear infection and dental caries, but some data were also supplied on the nature of the link between early childhood caries and middle ear infection.

Conclusion: Increased Streptococcus mutans levels in early childhood together with other contributory risk factors such as middle ear infection could enhance the incidence of early childhood dental caries.

Relevance: Male breast cancer (BC) is one of the rarest diseases and accounts for 1/100 of detected BC cases in both sexes. About 30-70%
of breast cancer cases in men develop against the background of gynecomastia, particularly its nodular form. The biology of the disease differs in
men, but the approaches to diagnostics and treatment are usually extrapolated from those used in women.
This study aimed to demonstrate the results of each stage of a male patient with BC diagnostics and treatment.
Methods: The article presents a clinical case of a male patient diagnosed with «Cancer in the right breast St III (T4NxM0), Edematous-infiltrative form with an intraductal component, upper outer localization. Immunohistochemically luminal subtype B without Her2neu expression». The
data from literary sources and clinical protocols on the male BC diagnosis and treatment were also reviewed.
Results: The patient received four courses of preoperative chemotherapy according to the “AС” scheme Doxorubicin 60 mg/m2
(CD 120 mg) +
Cyclophosphamide 600 mg/m2
(CD 1200 mg). Intermediate instrumental and laboratory control and assessing the response to treatment according
to the RECIST criteria are planned.
Conclusion: The presented rare clinical case of male BC demonstrates that diagnostics and treatment at the initial stage remain the same as
recommended for women. Identical preoperative and adjuvant chemotherapy regimens are applicable. Since most male BC express estrogen receptors, endocrine therapy such as tamoxifen is the kind of routine for adjuvant male BC treatment. This article describes the performed laboratory
and instrumental diagnostics and preoperative chemotherapy treatment of the patient. The second part of the publication will present the results of
the performed chemotherapy and surgical treatment and recommendations issued to the patient
STERNUM TUMOR SURGICAL TREATMENT METHOD: A CLINICAL CASE
Authors: Pyssanova Zh.
Published: July 2022

Relevance: Sarcomas are relatively rare. They make up 1% of all malignant neoplasms in adults, of which about 10-15% appear in the chest
wall. Unlike primary tumors, metastatic bone tumors occur 2-4 times more often, while the sternum is affected in 9% of all metastatic bone lesions.
A review of the literature and analysis of patients with chest wall tumors showed that surgical treatment might be the best option for primary tumors
and some secondary chest wall tumors.
Chondrosarcoma (12%) is the most common primary chest bone sarcoma and originates from the anterior segment of the ribs, less often from
the sternum, scapula, or clavicle.
The purpose was to present the outcome of a sternum sarcoma surgical treatment with a simultaneous reconstruction of an extensive postoperative defect at the Kazakh Institute of Oncology and Radiology (Almaty, Kazakhstan).
Methods: The article reviews the literature on the treatment of chest wall tumors and describes a clinical case of a patient with chondrosarcoma of the sternum. After subtotal resection of the sternum 2-3 cm away from the tumor margins, the patient underwent reconstructive plastic
surgery. Synthetic material was used to stabilize the chest wall, prevent paradoxical breathing, and replace the defect.
Result: No recurrence of the main process was registered after radical removal of the sternum tumor with the simultaneous reconstruction of
the defect with synthetic material. Given the prevalence of the tumor, intraoperative suturing of the subclavian vein was performed, which led to
vein thrombosis in the postoperative period.
Conclusions: The key to successful sternum tumor treatment is early recognition and radical removal with adequate margins. Complete excision with broadly negative microscopic margins at the first operation is paramount since local recurrence increases the risk of systemic metastasis
and death. Thus, standard guidelines are required to ensure chest wall sarcomas proper treatment.
