Authors: Mwiinga Fair Banji , Malimba Roster Chihwaka , Nzima Mutinta Mirriam , Chongo Billiat , Banda Malambo Faith , Chisoya Hope , Tembo Joan , Sakala Edward
Published: December 2023

Erb-Duchenne paralysis is a neurological condition characterized by paralysis of the arm which occurs due to injury of the upper trunk of C5-C6 of the brachial plexus and can lead to disturbances in movement and sensation. Erb-Duchenne paralysis commonly presents with a “Waiter’s Tip” deformity characterized by elbow extension, medial rotation of the arm, forearm pronation, and wrist flexion. Management of Erb-Duchenne paralysis may involve strengthening exercises, range of motion exercises, manual therapy, and neuromuscular electrical stimulation. However, in most cases, the diagnosis of Erb-Duchenne paralysis is not detected early enough for rehabilitation outcomes to be maximized. We herein report a case of a 6-months old child who had Erb-Duchenne paralysis in the left upper limb. The aim of this case report is to highlight the importance of early detection and rehabilitation of Erb-Duchenne paralysis. Furthermore, the report also discusses the physiotherapy techniques that can be used to optimize outcomes.
Implementation of Enhanced Recovery after Surgery at a General hospital in Zambia
Authors: Karachentsev Sergiy
Published: December 2023

Background: Enhanced recovery after surgery (ERAS), with its aim of reducing operative stress and accelerating rehabilitation, became a standard perioperative care in multiple surgical specialties in developed world. However, little is known about the implementation of the fast-track pathways in a low-resource environment. The objective of the study was to describe our experience and share lessons obtained in using ERAS protocol in general surgery patients.

Methods: In this descriptive study, all consecutive patients with no age restrictions undergoing elective and urgent abdominal surgery were assessed for inclusion in ERAS program. A retrospective analysis encompasses 98 patients aged two weeks to 87 years with male to female ratio of 2.3:1. Outcomes were functional recovery, postoperative complications, and length of hospital stay.

Results: All elements of ERAS protocol including minimal incision length laparotomy and accelerated postoperative care were used; however, certain components were modified depending on the availability of the resources and patient’s condition. Postoperative period complicated in 17.4% of cases, seven patients (7.4%) died after urgent operations, and no mortality was recorded after elective procedures. Median length of stay was 4.0 days. Local and systemic septic complications, paralytic ileus and performing of the stoma reversal procedure during the same hospital stay were reasons for delayed discharge.

Conclusion: This study indicates that employment of ERAS program for general surgery population at a second level hospital is feasible and safe. Further larger-scale studies are needed.
A Systematic Review on the Cost-Effectiveness of Intra-Articular Injections for Pain Relief in Symptomatic Patients with Osteoarthritis
Authors: Lwando Alex , Chiluba Brian Chanda
Published: December 2023

Background: This systematic review aimed to assess the quality of published economic evaluations of ultrasound-guided intra-articular injections for symptomatic management of osteoarthritis, explore their scope and diversity, and determine their cost-effectiveness.

Methods: Relevant electronic databases were systematically searched for studies published from January 2009 to June 2019. Keyword searches and Boolean operators were used to retrieve relevant literature. The PICOTS framework was utilized to define key research questions and guide the literature search. Duplicate removal, title and abstract screening were conducted to exclude irrelevant articles. Data from each study were extracted using a standardized form and summarized in an Excel spreadsheet. The SIGN quality appraisal tool for economic evaluations was employed to assess the quality of each study.

Results: The initial database search yielded 238 articles, with 35 duplicates removed. Following title and abstract screening, an additional 198 articles were excluded due to not meeting the inclusion criteria. Full-text manuscripts of the remaining 5 articles were reviewed. Based on the quality appraisal, 4 out of the 5 studies were excluded. One study was not a primary study, one was still ongoing, and two were not economic evaluations. Due to the limited number of included studies, no subgroups were identified.

Conclusions: This study provides evidence that ultrasound-guided intra-articular injections significantly improve clinical outcomes and enhance cost-effectiveness in the management of osteoarthritic joints. However, the scarcity of relevant studies highlights the need for further research to strengthen this finding.

Published: December 2023

The vegetable and fruit commodity business has good prospects for continued development. Vegetable production continues to increase from year to year. On the other hand, Indonesian people's consumption of vegetables is still low. PT XYZ is a company operating in the vegetable distributor sector. It faces the challenges of increasingly fierce competition and changes in customer purchasing patterns since the Covid-19 outbreak. The aim of this research was to identify business models, formulate alternative strategies, formulate priority strategies and formulate new business models that can be implemented to develop PT XYZ's business. Identification of PR XYZ's business model was carried out using the Business Model Canvas (BMC). Next, a SWOT analysis was carried out on the 9 elements of the Business Model Canvas, the results of which were also used to carry out IE analysis (EFE and IFE). From the IE analysis, PT XYZ's position was in quadrant V (Hold and Maintain). Commonly used strategies are Market Penetration and Product Development). From SWOT Matrix analysis (SO, WO, ST and WT). on the key factors of EFE and IFE, alternative strategies were obtained which were then prioritized using the Quantitative Strategic Planning Matrix (QSPM), namely: forming a research and development section, evaluating vegetable processing processes, developing vegetable derivative products, carrying out more active marketing activities, developing marketing to the hotel, restaurant and cafe (HOREKA) segment, mapping vegetable suppliers,  developing marketing to the online segment, creating a cooperation program that can bind suppliers, and opening a warehouse in Jakarta to reduce costs.

Authors: Drawert Heinz Arno
Published: December 2023

The state of knowledge regarding rivulids in Bolivia is still limited and has some significant gaps. With the aim of synthesizing and systematizing the available information, which is often scattered, a monographic review is presented that examines the knowledge status of the Rivulidae family and provides an updated inventory of the species present in the country, based on valid records supported by voucher specimens deposited in scientific collections. The presence of 31 species of the Rivulidae family in Bolivian territory is confirmed, distributed across 10 genera and belonging to two subfamilies: Cynolebiinae and Rivulinae. Furthermore, it is validated that 58% (18 species) are endemic to Bolivia, while 25.8% (8 species) have a highly restricted distribution and are recorded only from their type localities. In the context of Bolivia, this work provides a solid foundation for future research and significantly contributes to the knowledge, and therefore the conservation, of this paradigmatic group of fish.

Post-translational modification (PTM) is a vital biological process significantly impacting protein structure and function. It involves adding functional groups to the main and side chains during and after protein synthesis, thereby modifying their structure and function. PTMs are essential in shaping proteins into their final, functional, and three-dimensional forms. While numerous PTMs are still under active investigation and exploration. Herewith, we briefly overview some of the most prevalent PTMs, elucidate their associated functions, and establish connections between PTMs and a diverse range of diseases. Notably, we elucidate the profound influence of PTMs on neurodegenerative diseases and cancer, and provide a deep understanding of their many effects. Lastly, it considers a concise overview of PTM computational methods and databases, shedding light on the cutting-edge techniques and resources used to analyze and explore post-translational modifications.

Demographic investigation of 700 cases with severe odontogenic abscess in the maxillofacial region: A 6-year retrospective study
Authors: Güler Rıdvan
Published: December 2023

Aim: The aim of this retrospective study is to retrospectively analyze the demographic distribution and treatment methods of patients with odontogenic abscess who applied to Dicle University, Faculty of Dentistry, Department of Oral and Maxillofacial Surgery between 2017 and 2022, and evaluate the findings.
Methods: Patient documents of 700 odontogenic abscess cases who applied to our clinic were collected and examined. The data obtained were analyzed according to gender, age, time, anatomical localization, and treatment options. All the data obtained were evaluated with statistical analysis.
Results: As a result of the statistical analysis; a total of 700 patients, including 400 men (57%), and 300 women (43%), were treated. Of the patients with a mean age of 33±18 years, 63% (440) were treated with extraoral drainage and 37% (260) with intraoral drainage. In terms of localization, the most common areas of odontogenic abscess formation were mandibular posterior (54% - 376 cases), maxillary posterior (26% - 184 cases), maxillary anterior (17% - 116 cases), and mandibular anterior (3% - 24 cases). The most common reasons patients came to the clinic were swelling, pain, fever, and trismus. The year 2022 was analyzed as the year with the most intensive patient treatment, and 2017 as the year with the least patient treatment. In the analyses, when looking at the distribution of gender and localization by years, there was no statistically significant difference (p>0.05), but when looking at the distribution of drainage techniques by years, it was determined that there was a statistically significant difference (p<0.001).
Conclusion: The demographic characteristics and treatment options of patients with odontogenic abscesses vary depending on the causative tooth area. Odontogenic infections can become life-threatening in a short time if left untreated. Intraoral and extraoral drainage are very important for success in the treatment of common odontogenic abscesses where medical treatment is inadequate.

The current study examined the role of mean levels of affect in the relation between affect dynamics and depressive symptoms. We analyzed data from seven studies that measured affect in daily life in adolescents and young adults (N = 1,448, age range = 11.7-29.9 years, 64.8% females). We tested main and interaction effects of affect dynamics (variability and inertia) and affect level on depressive symptoms, separately for positive affect (PA) and negative affect (NA). For PA, we found mostly main, but no interaction effects. Depressive symptoms were associated with more PA variability and less PA inertia, indicating that depressive symptoms in young people may be characterized by more variable and less lingering PA, independent of PA mean levels. For NA, we found a significant moderation effect between NA variability and NA levels for depressive symptoms at baseline. For individuals with low NA levels, high NA variability was associated with more depressive symptoms. In contrast, for individuals with high NA levels, high NA variability was associated with fewer depressive symptoms. These results suggest that the relative adaptiveness of NA variability depends on overall NA levels and underscores the need for a more nuanced understanding of affect variability in depression.
The Effect of AlTi5B1 and ALTAB Ti80 with a Combination of AlSr15 and Mg Additions on Strength and Ductility of A356 Aluminum Alloys
Authors: Mostavan Afghany , Setiawan Asep Ridwan , Basuki Arif , Ardy Husaini
Published: December 2023

The current study aims to analyze microstructural changes affecting the A356 aluminum alloy, a hypoeutectic Al-Si-Mg alloy. This aluminum alloy is well-known for its strength, resistance to corrosion, lightweight, and heat treatability. The main objective of this research is to improve the strength and ductility of A356 alloys by using a synergistic strategy that includes AlTi5B1 and ALTAB Ti80 for microstructural alteration in combination with AlSr15 and Mg. The experimental results show that including all constituents in the as-cast condition enhances the ultimate tensile strength and elongation. Furthermore, in the heat-treated state, the addition of ALTAB Ti80 effectively maintains tensile strength (σuts=233.7 MPa), yield strength (σy=180.3 MPa), and elongation (e=5.8%). Additionally, when combined with Mg, the tensile strength and yield strength exhibit further improvement (σuts=253 MPa and σy=215.7 MPa); however, elongation is significantly reduced (e=2.7%)

This study aims to report the findings of an investigation into the separation of lithium and magnesium ions in the artificial brine water. The artificial brine water contains concentrations of magnesium, calcium, and lithium cations that closely resemble the concentrations seen in natural brine water sourced from Gunung Panjang using magnesium chloride, calcium chloride, and lithium chloride p.a. The objective of this experiment was to investigate the impact of pH and the addition of sodium silicate on the separation of magnesium and calcium ions from lithium ions in artificial brine water. The best outcomes were achieved when the pH of the brine water was set at 10, and sodium silicate was added in a stoichiometric ratio of 219%. These parameters led to a lithium content of 90.06%, magnesium removal of  70.32%, and a Mg/Li ratio of 6.29, indicating a substantial presence of magnesium ions precipitated as solids with pyroxene (MgSiO3) phase. This research also succeeded in increasing the lithium content by 94.28% and reducing the Mg/Li ratio to 4.96 after the precipitated solids were subjected to a water-leaching process.

Remanufacturing the main frame of a mining dump truck can save cost, energy, and materials in heavy equipment industries. It also can reduce CO2 emissions for environmental preservation to achieve sustainability. However, since the mainframe received a dynamic load during operation, it presumably leaves accumulated residual stresses in the frame. The residual stress, particularly tensile residual stress, stands out as a primary contributing factor to the initiation of cracks, which may ultimately result in failures. In this paper, the residual stress of the used mining dump truck main frame was identified by modeling simulation using FEA (finite element analysis) and actual measurement using a portable x-ray residual stress analyzer with the cos α method. The results showed that the weld area subjected to dynamic loads exhibited the highest tensile residual stress, reaching approximately +772 MPa. This specific region emerges as a critical area demanding attention during the remanufacturing process. The application of PWHT (post-weld heat treatment) at 400 °C for 1 hour effectively reduced residual stress on the weld joint, predominantly tensile residual stress, by more than 80%.

Medical applications occasionally require PSI (patient-specific implant) designs to match the implant bone’s geometry. To verify and predict failures of the design as well as a treatment before the manufacturing process, FEA (finite element analysis) is employed to simulate when given a specific number of loads. Plenty of studies have done the FEA using a couple of types of software; however, to the best of our knowledge, there is no literature to compare those several FEA results with a comparable experiment. This study further analyzes material stress, particularly to compute the VMS (Von Misses stress) of the Ti6Al4V bone plate. Furthermore, this study proposes to examine and deliver a comprehensive understanding using the four most used software of COMSOL, Ansys, Abaqus, and Autodesk Inventor. The results of those four simulations are then compared with the stress test through the Hardness Vickers test. This study will contribute significantly as a novel comparison between VMS and hardness test as a stress prediction in an implant material.

Currently, more than 60% of nickel processing is carried out using nickel sulfide as a raw material. Nonetheless, due to the depletion reserves of nickel sulphide, nickel laterite has drawn a lot of interest to be processed as raw material. Nickel laterite in Indonesia is generally found in low grades, with nickel concentration of <1.15%. One method of treating nickel limonite is leaching in a sulfuric acid solution. This study aims to determine the reaction rate in the leaching process of calcine nickel limonite and the effect of sulfuric acid concentration and leaching temperature on the percent nickel extraction. In this research, the limonite ore from Pomalaa, Southeast Sulawesi, Indonesia, which has undergone a reduction process, was used as raw material. This research was conducted by leaching method on nickel limonite calcine using sulfuric acid reagent with 0.2, 0.5, and 1 M concentration variation, temperature variations of 60, 70, and 90°C, stirring speed 500 rpm, and %S/L (w/w) 10%. In this leaching research, the activation energy obtained at a sulfuric acid concentration of 0.2, 0.5, and 1 M are 13,7379 kJ/mol, 19,7582 kJ/mol, 20,3161 kJ/mol, respectively. The leaching process of nickel limonite calcine was controlled by diffusion. The optimum nickel extraction percentage in this study was 97.45%, obtained at a concentration of 1 M sulfuric acid, temperature of 70 °C, and leaching time of 240 minutes.

O presente trabalho foi desenvolvido na pediatria do Hospital Universitário Professor Edgard Santos da Universidade Federal da Bahia nos meses de janeiro a abril de 2023, com crianças na faixa etária entre 6 a 12 anos. Teve como objetivo maior, observar as aprendizagens e a motivação a partir de brincadeiras e jogos elaborados com a reutilização de materiais. As observações foram realizadas diariamente durante a aplicação e/ou construção dos jogos/brinquedos propostas às crianças/pacientes. Alguns recursos foram construídos juntamente com a criança com o objetivo de trazer maior motivação. Ademais, a reutilização de materiais preserva os recursos naturais diminuindo a poluição gerada por plásticos, caixas, papéis e outros que podem ser reaproveitados ao invés de irem para o lixo dando-lhes um destino consciente. A metodologia empregada foi a técnica da observação participante, que permite uma pesquisa de cunho teórico-empírico (pesquisa de campo), que faz uso dos sentidos para obtenção de determinados aspectos da realidade. Diante disso, são descritas as situações ocorridas no leito do paciente de acordo com o jogo/brinquedo utilizado. Para uma melhor análise dos resultados, as descrições são realizadas individualmente ou em grupo dependendo dos jogos/brinquedos em questão. Para além disso, os recursos lúdicos no ambiente hospitalar são base prioritária das práxis pedagógicas. Podemos afirmar então que, os recursos lúdicos são excelentes alternativas para trabalho pedagógico.

Published: December 2023

Apesar da redução dos casos agudos da doença de Chagas (DC) no Brasil, ainda existem muitos pacientes na fase crônica em situação clínica desassistida. Este trabalho objetivou avaliar a soroprevalência e aspectos clínico-epidemiológicos das pessoas com a DC em Jataí-GO e analisar aspectos biológicos do Trypanosoma cruzi isolado por hemocultura. Os pacientes foram rastreados pela análise dos prontuários de doadores de sangue do Hemocentro de Jataí-GO (2000 a 2021). A hemocultura em meio LIT foi realizada pela coleta de 10 mL de sangue venoso. Realizou-se uma entrevista para a obtenção de informações clínico-epidemiológicas. Doze pacientes foram diagnosticados com a DC e foi realizada a hemocultura e entrevista em seis destes. Média de idade: 45,3 anos; 50% do sexo masculino e 50% do feminino; 66,7% apresentavam cor parda; 41,7% natural do estado de Goiás e 41,7% da Bahia. Todos apresentavam a forma crônica indeterminada e apenas 25% receberam tratamento com benzonidazol. A hemocultura foi positiva em apenas um dos pacientes, indicando baixa parasitemia. A entrevista evidenciou 83,3% dos pacientes com baixa situação socioeconômica e infância em ambiente rural; 83,3%, provavelmente, infectaram-se pela via vetorial; nenhum paciente fazia monitoramento clínico específico para a DC e dois apresentavam sintomas sugestivos de evolução para as formas digestiva e cardíaca. Conclui-se que muitos profissionais de saúde ainda não estão atualizados sobre o diagnóstico e tratamento da DC e muitos pacientes não estão recebendo tratamento etiológico e não estão sendo monitorados clinicamente visando a prevenção da evolução para formas graves da DC.

The development of tourism in West Java in recent years has shown an increasing trend in domestic tourists until 2021. The increased number of domestic tourists has had an impact on West Java's economic activity. However, the tourism sector itself is not defined as a distinct sector in economic statistics, and as a result, the economic impact from tourism contributions is not quite noticeable, especially in West Java Province. This study aims to highlight the impact of tourism on the economy of West Java by examining domestic tourist spending in 2021 and its effect on the economy. The study estimates the multiplier effect of domestic tourists' spending on production, income, gross value added, and employment, to determine the economic impact of tourism. The results of this study indicate that tourism has a significant impact and plays a significant role in the West Java economy, contributing 9.28% to GRDP and 12.39% of the total working population in West Java in 2021.
