Authors: Sandberg Chaleece W. , Conyers Liza M. 
Published: March 2021

PurposeThe purpose of this article is to show how the client-focused considering work model (CFCWM) can be adapted to persons with aphasia as a way to provide a framework for rehabilitation counselors to use when helping persons with aphasia assess their readiness to work.MethodThis article first provides a basic overview of aphasia and the communication challenges that persons with aphasia experience. We then provide a review the CFCWM as well as a rationale for extending it to persons with aphasia. Finally, we present a case study that walks through the barriers and facilitators to returning to work for persons with aphasia, framed within the CFCWM.ResultsExtending the CFCWM to persons with aphasia provides much needed guidelines for professionals working with this population, creates opportunities for education among stakeholders, and provides a theoretical foundation for needed research aimed at understanding and better addressing the vocational needs of persons with aphasia.ConclusionsThis article shows how the CFCWM can be extended to the population of persons with aphasia and highlights how vocational counselors and speech-language pathologists can work together to better serve this population.

Authors: Acuña Alexander J. , Jella Tarun K. , Samuel Linsen T. , Schwarzkopf Ran , Fehring Thomas K. , Kamath Atul F. 
Published: March 2021

Background:
Investigations into reimbursement trends for primary and revision arthroplasty procedures have demonstrated a steady decline over the past several years. Revision total hip arthroplasty (rTHA) due to infection (rTHA-I) has been associated with higher resource utilization and complexity, but long-term inflation-adjusted data have yet to be compared between rTHA-I and rTHA due to aseptic complications (rTHA-A). The present study was performed to analyze temporal reimbursement trends regarding rTHA-I procedures compared with those for rTHA-A procedures.

Methods:
The Centers for Medicare & Medicaid Services (CMS) Physician Fee Schedule Look-Up Tool was used to extract Medicare reimbursements associated with 1-stage and 2-stage rTHA-I as well as 1-stage rTHA-A procedures from 2002 to 2019. Current Procedural Terminology (CPT) codes for rTHA were grouped according to the American Academy of Orthopaedic Surgeons coding reference guide. Monetary values were adjusted for inflation using the consumer price index (U.S. Bureau of Labor Statistics; reported as 2019 U.S. dollars) and used to calculate the cumulative and average annual percent changes in reimbursement.

Results:
Following inflation adjustment, the physician fee reimbursement for rTHA-A decreased by a mean [and standard deviation] of 27.26% ± 3.57% (from $2,209.11 in 2002 to $1,603.20 in 2019) for femoral component revision, 27.41% ± 3.57% (from $2,130.55 to $1,542.91) for acetabular component revision, and 27.50% ± 2.56% (from $2,775.53 to $2,007.61) for both-component revision. Similarly, for a 2-stage rTHA-I, the mean reimbursement declined by 18.74% ± 3.87% (from $2,063.36 in 2002 to $1,673.36 in 2019) and 24.45% ± 3.69% (from $2,328.79 to $1,755.45) for the explantation and reimplantation stages, respectively. The total decline in physician fee reimbursement for rTHA-I ($1,020.64 ± $233.72) was significantly greater than that for rTHA-A ($580.72 ± $107.22; p < 0.00001).

Conclusions:
Our study demonstrated a consistent devaluation of both rTHA-I and rTHA-A procedures from 2002 to 2019, with a larger deficit seen for rTHA-I. A continuation of this trend could create substantial disincentives for physicians to perform such procedures and limit access to care at the population level.

Delayed Displacement of a Subtle Sacral Insufficiency Fracture Unmasking Lumbopelvic Instability
Authors: Campbell Sean T. , Firoozabadi Reza 
Published: March 2021

Case:
There is limited literature reporting on sacral insufficiency fractures as a cause of lumbopelvic instability. We describe the presentation, treatment, and clinical outcome with a 2-year follow-up of a woman who sustained a low-energy spinopelvic dissociation diagnosed with magnetic resonance imaging. There was significant delayed displacement, and the patient was treated surgically with percutaneous iliosacral and trans-sacral screws.

Conclusion:
U-type sacral insufficiency fractures may be subtle on advanced imaging and must be followed closely if nonoperative treatment is chosen. These patients may require surgical intervention. Iliosacral screws and lumbopelvic fixation are treatment options, each with advantages and disadvantages.

Published: March 2021

Case:
We present a case of a 41-year-old male bodybuilder with a partial delaminated quadriceps tendon rupture after a traumatic injury. Partial quadriceps tendon tears are rare overall and usually are treated nonoperatively with conservative management depending on the patient’s limitations. He was found to have an intact superficial quadriceps tendon with a partial thickness tear of the vastus intermedius and delamination of the undersurface quadriceps tendon precluding active knee extension.

Conclusion:
To our knowledge, there has never been a reported partial quadriceps tendon tear with delamination of the undersurface, causing a complete extensor mechanism failure necessitating operative repair.

Abstrak. Pemahaman konsep merupakan hal yang sangat diperlukan dalam pembelajaran matematika, sehingga bisa memecahkan masalah dalam pembelajaran matematika sesuai dengan konsep yang dipahami. Sebaliknya, apabila tidak memahami konsep yang selanjutnya disebut miskonsepsi tidak bisa memecahkan masalah dalam pembelajaran matematika. Penelitian ini menggunakan metode deskriptif dengan pendekatan penelitian kualitatif. Teknik pengumpulan data adalah tes tertulis dan wawancara. Soal tes yang digunakan adalah soal tes berbentuk three tier test. Siswa kelas VIII SMP yang berjumlah 28 orang siswa dijadikan sebagai populasi, dan sebanyak 6 siswa dari 28 siswa dijadikan sebagai subjek penelitian. Hasil penelitian ini, rata-rata siswa mengalami miskonsepsi pada soal nomor 3 dan 4 yang menanyakan tentang himpunan penyelesaian dan soal cerita yang berkaitan dengan kehidupan sehari-hari. Siswa yang mengalami miskonsepsi dikarenakan belum mampu menentukan sebarang bilangan untuk mengeliminasi salah satu variabel serta belum mampu menerjemahkan soal cerita ke dalam bentuk matematika. Selain mengalami miskonsepsi siswa juga lucky guess (menjawab benar dengan menebak). Adapun subyek yang mengalami miskonsepsi pada soal nomor 3 berjumlah 4 siswa dan soal nomor 4 berjumlah 4 siswa. Berdasarkan hasil penelitian dengan menggunakan three tier test maka dapat disimpulkan bahwa sebagian besar siswa mengalami miskonsepsi pada salah satu soal bahkan lebih. Selain mengalami miskonsepsi siswa juga mengalami lucky guess serta mengalami konsepsi ilmiah.

COVID-19 Infection among People with HIV/AIDS in Africa: Knowledge Gaps, Public Health Preparedness and Research Priorities
Authors: Essien Ekere James , Mgbere Osaro , Iloanusi Sorochi , Abughosh Susan V. 
Published: March 2021

The emergence of novel virus SARS-CoV-2 that causes COVID-19 has complicated Africa’s public health challenges, especially with the pre-existing epidemics such as HIV/AIDS. We highlight the known evidence related to COVID-19 infections among people with HIV (PWH) with specific reference to Africa. The knowledge gaps, level of public health preparedness and the potential research priorities are also outlined. Although the epidemiology and clinical course of COVID-19 in HIV patients are evolving, existing evidence indicate that the disease outcomes are comparable to that of the general population. However, PWH with low CD4 cell counts may have worse outcomes than individuals with restored immunity, whereas old age and co-morbidities such as obesity, hypertension and diabetes can further increase their overall risk. While there may be slight disruption of HIV service delivery in selected African countries, the resilience and resourcefulness of others have helped to sustain HIV service delivery and enhanced the level of public health preparedness and fight against the pandemic. The paucity of data and research studies on HIV-COVID-19 coinfection in Africa, call for concerted efforts to address these limitations.

Authors: Rusdiana S , Ishak Andi B. Lompengeng , Ferasyi Teuku Reza 
Published: March 2021

The research objective was to determine the beef cattle business development strategy in increasing the economic value of farmers in Sukabumi Regency. The research was conducted in Ciracap District, Sukabumi Regency, West Java in 2020. The research used survey methods and interviews with 65 farmers and 9 extension workers from BPP Sukabumi Regency. Primary data and secondary data were analyzed using statistical analysis, economic analysis and Swot analysis descriptively and quantitatively. The results showed that the farmers' average land ownership was 1.57 ha/farmer. The farmer profit is IDR. 250.548.975 /year, the value of R/C is 1.14. The related variable (dependent) which affects farmer profit and business efficiency of beef cattle has an effect on the95% confidence level. Swot analysis of internal and external factors in the development of beef cattle business showed the strengths of the working area of the Sukabumi Regency BPP including available labor, agricultural land area, grazing land, the number of cows being raised and the support of government institutions, private companies and other institutions as well as livestock market opportunities wide open. The weaknesses are limited land resources, business capital, increased feed prices and the price of beef cattle that were controlled by middlemen. It is suggested that strategies to increase beef cattle population and economic value of the farmers are by optimizing the function of empty land as grazing land and forage cultivation. Business cooperation, marketing networks and guaranteed beef cattle prices are pivotal in order to take advantage of relatively unfulfilled market opportunities.

Published: March 2021

The clinical breast self-examination is one of the strategies to prevent breast cancer to women. Previous study was conducting to promote breast self-examination, but the study did not consider about the role of culture on health behavior. The purpose of this quasi-experimental design was to examine the effect of cultural-based breast self-examination (BSE) educational program on BSE self-efficacy among nursing students. The cultural-based BSE educational program was developed based on Bandura’s Social Cognitive Theory and Islamic Culture. A stratified proportionate random sampling method was employed to recruit nursing students at Public Nursing College, Faculty of Medicine, Syiah Kuala University in Aceh, Indonesia. Seventy-six students who met the inclusion criteria were recruited, 36 students were in the experimental group and 40 students were in the control group. The experimental group received the cultural-based BSE educational program including exploring Islamic mandate on prevention and individual responsibility in health promotion and cultural related beliefs toward BSE, health education, BSE training, and follow-up. The BSE self-efficacy scores were examined after 3 weeks of program implementation. The statistical analysis was conducted using dependent t-test and independent t-test. The results showed, the BSE self- efficacy of the nursing students in the experimental group were significantly higher than before participation ( t (35) =-5.02, p .001). Further, the BSE self-efficacy score in the experimental group was significantly higher than thecontrol group after participation the program (t (74) = 3.49, p .01). The result showed differences of the overall BSE self-efficacy and the subscale: BSE procedural efficacy (p .01), but not significant differences for the subscale: BSE barrier management efficacy (p .05). The cultural-based BSE educational program is effective in enhancing BSE self-efficacy among nursing students. The study suggests that the application of the cultural-based BSE educational program would be extended for other women and other nursing students in different areas.
A protocol to develop visual geographic models of socio-economic and public health data

Published: March 2021

Abstract
Understanding the impact of socio-economic inequality on health outcomes is arguably more relevant than ever before given the global repercussions of COVID-19. With limited resources, innovative methods to track disease, population needs, and current health and social service provision are essential. One approach of interest is the implementation and integration of mapping software. This approach develops multi-layered interactive maps to demonstrate relationships between socio-economic and health data. Paediatric vaccination uptake and readmission rates are used as an example; however, the wider application of this method is not limited to these sets of health data. This approach aims to improve the interpretation and accessibility of data by creating a simple visual model with little need for additional technical experience beyond the guidance of the protocol.
Expression of Foreign Proteins in&nbsp;Escherichia coli
Authors: Iftikhar Ali 
Published: March 2021

Abstract
BackgroundOptimization of conditions for the recombinant production of proteins in a prokaryotic expression system is essential as the recombinant proteins impose a metabolic burden on cell's growth leading to low protein yield and low protein expression resulting from cell death.Main textThe concentration of media components is optimized to accommodate for depleted nutrients due to foreign protein expression. The temperature is optimized to reduce proteolytic degradation and accumulation of protein as inclusion bodies in Escherichia coli. The concentration of inducer and time of induction for high protein yield is also optimized. These optimization conditions depend on the promoter under which the gene of interest is present and the characteristics of the target protein.ConclusionIn the past few years, many optimization conditions for the production of recombinant proteins in Escherichia coli have been studied. These conditions depend mainly upon the promoter used to produce protein and the type of protein produced. Optimizing the expression parameters of protein produced in Escherichia coli ensures maximum yield of the desired protein.
