Published: February 2022

Background:

The need for autologous blood transfusion in our tertiary hospitals to restore patients' hemodynamics with little or no complications cannot be overemphasized.

Aims:

This study is aimed at assessing surgeons' challenges and patients' readiness to accept autologous blood transfusion.

Materials and Methods:

It was a cross-sectional study conducted at Enugu State University Teaching Hospital, University of Nigeria Teaching Hospital, Enugu, and National Orthopaedic Hospital, Enugu, from September to December 2020. A convenient sampling method was adopted in the distribution of questionnaires, and a total of 67 surgeons were enrolled in the study. Collated data were analyzed using SPSS software 21.

Results:

The study revealed that 60% of the respondents claimed that commercial donors were observed to be the major source of allogenic blood donation. Consequently, 34.3% and 80.6% of the respondents admitted that blood-borne transmissible infections and blood transfusion reactions, respectively, were still a challenge in their practice. The outcome from this study also showed that 59% of the respondents claimed that their patients are not knowledgeable enough to make informed decision on the use of autologous blood transfusion while 52.4% of the respondents admitted that they do not have the facility for processing autologous blood transfusion. For the surgical specialties, all were willing to prescribe autologous blood transfusion for their patients, though no statistical difference (P < 0.05) exists among the specialties.

Conclusion:

Autologous blood transfusion has remained the mainstay as effective and safest means of blood transfusion in overall patient care; hence, surgeons should incorporate this concept into their practice to enable patients make an informed decision.
Utilization of Orthodox Eye Care Services among Visually Impaired Adults in Jos North Local Government Area of Plateau State
Authors: Umar Fatima Hudu , Odugbo O. P. , Mpyet C. D.
Published: February 2022

Background:

Evidence shows that poor utilization of available eye care services by potential beneficiaries is a major barrier to reducing the burden of visual impairment (VI) and blindness.

Aim:

We sought to determine the extent of utilization and barriers to uptake of orthodox eye care services among adults with VI in Jos, the capital of Plateau state, Nigeria.

Materials and Methods:

A population-based cross-sectional study using cluster sampling technique was conducted. Twenty-two clusters were chosen: from each cluster, 39 persons recruited for participation were interviewed to obtain demographic data and then examined to determine the visual acuity. Individuals with visual acuity of <6/18 had detailed ocular examination. Information on access to any eye services in the locality was obtained. The data from individual subjects were collated and analyzed using the statistical package for social sciences version 20.

Results:

The study sample included 858 participants. Of the 160 participants with VI, 92 (57.5%) had sought eye care whereas 68 (42.5%) did not. It was found that utilization of eye services varied across the wards with Tafawa Balewa (100%), Vandapuye (100%), and Jenta Apata (100%) wards having the highest percentage of eye care utilization whereas Kabong (0%) and Mazah (11.1%) had the lowest eye care utilization rate. Factors associated with previous use of eye services were literacy (odds ratio = 1.41, P = 0.10) and blindness (odds ratio = 1.37, P = 0.09). Cost 39 (57.4%), being destined to be visually impaired 13 (19.1%), and old age 7 (10.3%) were found to be the most cited barriers to the use of eye services.

Conclusion:

The use of eye care services among visually impaired participants was low in this urban local council; this can be enhanced by health education and awareness campaigns. The role of community participation in eye care is important so as to improve the uptake of existing eye services.

Published: February 2022

Background:

As the coronavirus disease 2019 (COVID-19) continues to ravage the world as a pandemic, there is a paucity of data in resource poor countries like ours on the clinical characteristics of these patients.

Aim:

The aim of our study was to find the sociodemographic, clinical, and laboratory characteristics of COVID-19 patients admitted in our facility between May and July 2020.

Materials and Methods:

A cross-sectional observational study was carried out on COVID-19 patients admitted during the study period. Their baseline demographic, clinical, and laboratory details were obtained from their clinical notes, recorded electronically, and analyzed.

Results:

Twenty-six COVID-19 patients were admitted during this period, with a mean age of 47.19 (standard deviation 16.56) years, and more males 16 (61.5%). Fever was the most common complaint 17 (65.4%), followed by breathlessness 15 (57.7%), weakness 11 (42.3%), and cough 9 (34.6%). Hypoxemia (SPO2 <93%) was present in 10 (38.5%) of patients at admission, with dyspnea being the most common abnormality on general physical examination 20 (76.9%). Eleven (42.3%) patients had associated comorbidities with hypertension being the most common 7 (43.7%), followed by diabetes mellitus 4 (25.0%). Just 3 (11.5%) patients had mild disease, 13 (50.0%) had moderate disease, and 10 (38.5%) had severe disease. Lower respiratory tract infection or suspected COVID-19 was the initial diagnosis in 10 (38.5%) of patients at admission, while 16 (61.5%) were admitted with other diagnosis. Leukocytosis was found in 8 (30.8%) patients, 14 (53.8%) patients had anemia, elevated urea in 20 (76.9%), and elevated Creatinine in 11 (42.3%). Seventeen (65.4%) patients were discharged home, 2 (7.7%) referred to another center for hemodialysis, while 7 (26.9%) died.

Conclusion:

Understanding the clinical and laboratory characteristics of COVID-19 in our local environment will be integral to earlier identification and treatment outcomes for our patients.
Does Leray’s structure theorem withstand buoyancy-driven chemotaxis-fluid interaction?
Authors: Winkler Michael
Published: February 2022

In a smoothly bounded convex domain

\Omega \subset \mathbb{R}^3

, we consider the chemotaxis-Navier–Stokes model

\begin{cases} n_t + u\cdot\nabla n = \Delta n - \nabla \cdot (n\nabla c), & x\in \Omega, \, t>0, \\ c_t + u\cdot\nabla c = \Delta c -nc, & x\in \Omega, \, t>0, \\ u_t + (u\cdot\nabla) u = \Delta u + \nabla P + n\nabla\Phi, \quad \nabla\cdot u=0, & x\in \Omega, \, t>0, \end{cases} \quad (\star)

proposed by Goldstein et al. to describe pattern formation in populations of aerobic bacteria interacting with their liquid environment via transport and buoyancy. Known results have asserted that under appropriate regularity assumptions on

\Phi

and the initial data, a corresponding no-flux/no-flux/Dirichlet initial-boundary value problem is globally solvable in a framework of so-called weak energy solutions, and that any such solution eventually becomes smooth and classical.

Going beyond this, the present work focuses on the possible extent of unboundedness phenomena also on short timescales, and hence investigates in more detail the set of times in

(0,\infty)

at which solutions may develop singularities. The main results in this direction reveal the existence of a global weak energy solution which coincides with a smooth function throughout

\overline{\Omega}\times E

, where

E

denotes a countable union of open intervals which is such that

|(0,\infty)\setminus E|=0

. In particular, this indicates that a similar feature of the unperturbed Navie–Stokes equations, known as Leray’s structure theorem, persists even in the presence of the coupling to the attractive and hence potentially destabilizing cross-diffusive mechanism in the full system (

Published: February 2022

ENT navigation has given new opportunities in performing Endoscopic Sinus Surgery (ESS) and improving surgical outcome of the patients` treatment. ESS assisted by a navigation system could be called Navigated Endoscopic Sinus Surgery (NESS). As it is generally accepted that the NESS should be performed only in cases of complex anatomy and pathology, it has not yet been established as a state-of-the-art procedure and thus not used on a daily basis. This paper presents an algorithm for use of a navigation system for basic ESS in the treatment of chronic rhinosinusitis (CRS). The algorithm includes five units that should be highlighted using a navigation system. They are as follows: 1) nasal vestibule unit, 2) OMC unit, 3) anterior ethmoid unit, 4) posterior ethmoid unit, and 5) sphenoid unit. Each unit has a shape of a triangular pyramid and consists of at least four reference points or landmarks. As many landmarks as possible should be marked when determining one of the five units. Navigated orientation in each unit should always precede any surgical intervention. The algorithm should improve the learning curve of trainees and enable surgeons to use the navigation system routinely and systematically.
Efficacy and safety of erdosteine in the treatment of chronic rhinosinusitis with nasal polyposis - a pilot study
Authors: Hoza J. , Salzman R. , Starek I. , Schalek P. , Kellnerova R.
Published: February 2022

Background: Erdosteine was originally developed as a mucolytic agent. It is a multimechanism substance with anti-bacterial, anti-oxidant, and most importantly anti-inflammatory effects. Given similar mechanisms of action (suppression of cytokines, including tumor necrosis factor α), it could become a reasonable alternative to currently used treatments with macrolides or steroids. Objective: To assess efficacy and safety of erdosteine in the treatment of chronic rhinosinusitis with nasal polyposis (CRSwNP). Methodology: A prospective non-interventional post-authorisation study comparing patients treated with erdosteine only or the combination of erdosteine and nasal corticosteroid spray for CRSwNP. The end-points were pre- and post-treatment changes in endoscopic score and subjective evaluation of CRSwNP related symptoms using a 22-item Sinonasal Outcome Test questionnaire. Patients underwent nasal endoscopy and filled the questionnaire before and after the treatment. Results: No patient experienced any adverse effect during the study. A comparison of pre- and post-treatment endoscopic findings and questionnaire values revealed significant reduction in both patient groups, with a significantly better response in the erdosteine only group. Conclusion: Based on this pilot study, erdosteine seems effective in the treatment of CRSwNP and might become a reasonable alternative to currently used medication. The therapeutical role of erdosteine needs to be further assessed.
Comparison of high-flow nasal oxygen therapy and noninvasive ventilation in COVID-19 patients: a systematic review and meta-analysis
Authors: Glenardi Glenardi , Chriestya Febie , Oetoro Bambang J , Mangkuliguna Ghea , Natalia Natalia
Published: February 2022

Background: Acute respiratory failure (ARF) is a major adverse event commonly encountered in severe coronavirus disease 2019 (COVID-19). Although noninvasive mechanical ventilation (NIV) has long been used in the management of ARF, it has several adverse events which may cause patient discomfort and lead to treatment complication. Recently, high-flow nasal cannula (HFNC) has the potential to be an alternative for NIV in adults with ARF, including COVID-19 patients. The objective was to investigate the efficacy of HFNC compared to NIV in COVID-19 patients.Methods: This meta-analysis was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Literature search was carried out in electronic databases for relevant articles published prior to June 2021. Odds ratio (OR) with 95% confidence intervals (CI) was used as the effect size index. The protocol used in this study has been registered in International Prospective Register of Systematic Reviews (PROSPERO; CRD42020225186).Results: Although the success rate of NIV is higher compared to HFNC (OR, 0.39; 95% CI, 0.16–0.97; P=0.04), this study showed that the mortality in the NIV group is also significantly higher compared to HFNC group (OR, 0.49; 95% CI, 0.39–0.63; P<0.00001). Moreover, this study also demonstrated that there was no significant difference in intubation rates between the two groups (OR, 1.35; 95% CI, 0.86–2.11; P=0.19). Conclusions: Patients treated with HFNC showed better outcomes compared to NIV for ARF due to COVID-19. Therefore, HFNC should be considered prior to NIV in COVID-19-associated ARF. However, due to relatively small sample size, further studies with larger sample sizes are still needed to better elucidate the benefit of HFNC in COVID-19 patients.
Electronic and optical properties of nickel-doped ceria: A computational modelling study
Authors: Miran Hussein A. , Jaf Zainab N.
Published: February 2022

Cerium oxide $\text{CeO}_2$, or ceria, has gained increasing interest owing to its excellent catalytic applications. Under the framework of density functional theory (DFT), this contribution demonstrates the effect that introducing the element nickel (Ni) into the ceria lattice has on its electronic, structural, and optical characteristics. Electronic density of states (DOSs) analysis shows that Ni integration leads to a shrinkage of Ce 4$f$ states and improvement of Ni 3$d$ states in the bottom of the conduction band. Furthermore, the calculated optical absorption spectra of an Ni-doped $\text{CeO}_2$ system shifts towards longer visible light and infrared regions. Results indicate that Ni-doping a $\text{CeO}_2$ system would result in a decrease of the band gap. Finally, Mulliken's charge transfer of the $\text{Ce}_{1-x}\text{Ni}_x\text{O}_2$ system exhibits an ionic bond between Ce or Ni and O, and covalent bonds between Ce and Ni atoms. The analysis of absorption spectra demonstrates that Ni-doped $\text{CeO}_2$ is a material with potential use in photocatalytic, photovoltaic, and solar panels.
Teleios in the Epistle of James
Authors: Yeo Seongjae
Published: February 2022

Teleios is an Hellenistic Greek term which refers to an end, goal, purpose or aim, and it
means complete, mature, or fully developed, finished. Teleios signifies consummate
soundness, and it includes the idea of being whole. In its numerous forms the term teleios arises 100 times in the Greek New Testament. The term was frequently used in the Epistle of James — τέλειον (James 1:4); τέλειον (James 1:17); τέλειον (James 1:25); τελεῖτε (James 2:8); ἐτελειώθη (James 2:22); τέλειος (James 3:2). The frequent use of teleios makes it possible to know that the author clearly expressed his perspective through this word. In the previous research on teleios, Patrick J. Hartin argues that the use of teleios in the Epistle of James is rooted in the Hebrew Scriptures and the LXX as a Jewish coloured term. Hartin’s view is fair to illuminate that teleios is based on the concept of state of the completeness and whole - hearted mental state. Yet, considering that teleios (James 3:2) is used for explaining the process into completeness, called, maturity, such a view of the author of James’ Epistle is closer to the view of the Classical Greek Philosopher, Plato, or the Hellenistic Jewish philosopher, Philo of Alexandria. In addition, teleios (James 1:17) which can be regarded as one of the divine attributes, might be traced back to Platonic or Philonic thinking. Thus, James’ author might be considered as a Hellenised Jew who combined a Jewish concept with a Hellenistic perspective through the term, teleios.
ANC’s step-aside rule through the eye of the missio politica as mandated by Missio Dei
Authors: Thinane Jonas Sello
Published: February 2022

The broader practice of politics in the world, while detached from the religion, cannot be
excluded from the mission of the Missio Dei. In fact, the question of mission and politics has prompted Professor Johannes Reimer to propose missio politica as a missiological framework that puts the mandate of mission and politics in one basket. Following this solid foundation, this paper will propose the use of missio politica as an important missiological framework to analyse the instrumentally useful politics in line with the ultimate goal of Missio Dei. In accordance with the tenets of both missio politica in the name of missio Dei, this paper will then consider the South African ANC's step-aside rule from a biblical perspective, arguing that the accounts of Samuel's leadership in 1 Samuel 8 and the story of Ananias with his wife in Acts 5:1-11 represent a somewhat biblical understanding of the step-aside rule. The ANC's step-aside rule only serves to relativize the need for a missio politica. This paper promises a better understanding of the relationship between mission and politics, such an understanding is a key to uncovering new ways to ensure a meaningful participation of all other sectors of
society in achieving the goal of Missio Dei. Missio politica represent what has been missing in the missiological discourse. Therefore, this framework needs to be further explored in order to emphasize the mandate of politics in accordance with the Missio Dei.
Simulation modeling - An effective method in doing business and management research
Authors: Tram Nguyen Thi Bich
Published: February 2022

Although simulation modeling is a popular method in doing scientific research for many disciplines, namely decision science, optimization, information technology. Social science disciplines, particularly business and management, still receive little attention in applying this method. The paper introduces simulation modeling as an effective method in doing business and management research using Dimensions database and comparative analysis to explore (1) suitability and contribution in general disciplines as well as business and management, (2) advantages and disadvantages, (3) common types of models, and (4) effective software that researchers could use for specific research problems. The findings of this study confirm that simulation modeling is an effective method in doing business and management research thanks to its abilities in dynamics reflecting the real world, abstracted illustration, and naturally accommodating more plausible behavioral assumptions. However, modelers need to be aware of computational possibilities, the model’s complexity, and validity which might impact the simulated research results. The objective of this study is a calling for more simulation-based research to tackle complicated study problems related to business organizations with advanced technology and powerful tools listed in the paper. Thus, modelers are served well by this work as a reference for basic knowledge related to simulation modeling in business and management research.

Authors: Oanh Truong Thi Hoang , Thanh Duong Ngoc , Be Hai Truong Thi
Published: February 2022

The purpose of this article is to assess the current situation of production and consumption of Unburnt Building Materials (UBMs) in the Mekong Delta, thereby proposing solutions to promote the consumption of UBMs in the Mekong Delta in the coming time. Research results from the survey of producers and customers organized as well as discussions with local officials show that the whole Mekong Delta has more than 120 producers consuming through 02 main channels. Sales channels that direct customers are construction contractors - organizational customers (accounting for 90%) and through construction material trading companies (about 10%). In general, both the production and consumption of UBMs in the Mekong Delta face difficulties. Limited production capacity, limited capacity of UBMs, and low consumer confidence in UBM products are typical difficulties. Planning for the development of UBMs, organizing production to improve the innovation capacity of manufacturers and construction contractors, strengthening the link between manufacturers and UBMs consuming partners, promoting product branding products, enhancing sales promotion innovation activities, etc. are the main solutions to promote this industry to develop more in the Mekong Delta in the coming time.

Published: February 2022

Truyền thông xã hội là một trong những công cụ xây dựng cộng đồng, cho phép người dùng kết nối với người khác bất kể vị trí và thời gian. Người lao động sử dụng các ứng dụng truyền thông xã hội khác nhau để chia sẻ kiến thức, giải quyết vấn đề, hợp tác và giao tiếp trong các tổ chức (Aral, Dellarocas, & Godes, 2013; Landers & Schmidt, 2016), từ đó nâng cao hiệu suất công việc. Tuy nhiên, việc truy cập vào phương tiện truyền thông xã hội có nhiều khả năng dẫn đến việc sử dụng quá mức và vô tình tạo ra một môi trường làm việc căng thẳng hơn, dẫn đến kết quả tiêu cực trong các tổ chức (Cao & Yu, 2019).

Nghiên cứu này xác định sự tác động và mức độ tác động của các kiểu sử dụng quá mức khác nhau của mạng xã hội đối với hiệu suất công việc thông qua sự căng thẳng tại nơi làm việc của 328 người lao động tại Ủy ban nhân dân quận Bình Thạnh (Thành phố Hồ Chí Minh, Việt Nam), cụ thể là các trưởng phó phòng ban và nhân viên làm việc trong văn phòng, được khảo sát trực tuyến vào tháng 05 năm 2020. Tính hợp lệ và độ tin cậy của dữ liệu đã được kiểm tra bằng CFA và SEM.

Kết quả của nghiên cứu này cho thấy Sử dụng quá mức nhu cầu xã hội của phương tiện truyền thông xã hội tại nơi làm việc tác động mạnh nhất và đáng kể tới sự căng thẳng tại nơi làm việc. Kế đến là Sử dụng quá mức nhu cầu thụ hưởng và Xung đột công nghệ-công việc. Sự căng thẳng tại nơi làm việc có tác động ngược chiều với hiệu suất công việc. Tuy nhiên, Sử dụng quá mức nhu cầu nhận thức không có mối quan hệ với sự căng thẳng tại nơi làm việc. Một số hàm ý quản trị được đề xuất dựa vào kết quả nghiên cứu để có thể sử dụng hợp lý phương tiện truyền thông xã hội, từ đó cải thiện mối quan hệ và hiệu suất của người lao động.
Informal Layman’s Response to the Publication of the Book The Church — Towards a Common Vision
Authors: Matić Zoran
Published: February 2022

The document The Church — Towards a Common Vision (TCTCV) of the Commission for Faith and Order within the World Council of Churches was published in Serbian, as a book, co-published by the Christian Cultural Center “Dr. Radovan Bigović,” Institute for Systematic Theology of the Faculty of Orthodox Theology at the University of Belgrade and Biblical Cultural Center, 2020, at the height of the coronavirus pandemic. Both the TCTCV book and the pandemic represent a spiritual and existential challenge. They provoke reception, reflection. Therefore, it is necessary to capture the contemporary context and meaning of publishing and researching literature dedicated to the topic of ecumenism in our Church. It is also expedient to look at history and significance of ecumenism as a general mission of the Church. The notable ecclesiocentricity of the book TCTCV can arouse our greater interest in orthodox and ecumenical ecclesiology, their comparative research, as well as in re-examining our own role and invocation in the ecumenical movement. Through statistical, epistemological, and contextual analysis of the concepts of the text of the book, we noticed some specifics and possibilities of encouragement for inclusive lay, consultative-democratic, and political-theological approaches in ecumenism. The grace of reading the book TCTCV is manifested, among other things, through arousing contemplation over the mystery of the Church, unity, communion. This secret could be explored mentally and spiritually, through a personal relationship, together, based on the experience of participating in a concreate community of the Church. The axiom about the Church as a community is at the heart of the content of this book, as well as the universal call to the Christ-loving hearts of many to use the book as an instrument for mutual acquaintance, rapprochement, and striving for a common, Eucharistic understanding of the Church and universal Christian unity. In general, this was the vision of Bishop Nicholai Velimirovich while participating in the ecumenical movement and infusing in it his own orthodox experience of the Church. It was also very impactful on prof. Dr. Radovan Bigović, who further elaborated modern ecumenical attitudes, clear and solid guidelines for our contemporary orthodox ecumenical orientation. Both of them, bishop Nicholai and Dr. Bigović are ecumenical and inclusive (unifying) persons and as such our encouraging paragons for ecumenical mission and above all ecumenical love. Relied on them and other ecumenical theologians we are gifted with an opportunity to get involved and to continue building our ecumenical tradition in which publishing plays a significant role.

Published: February 2022

This manuscript aimed at establishing how students who are blind manage to remember what they are taught during the lecture hours at Kwame Nkrumah University. The objectives which guided this study aimed at determining how students who are blind remembered their academic work, establishing what helped students who are blind remembered their work and the consideration of what was most helpful to students who are blind in remembering their academic work. The researcher used semi-structured interview, document study and observation checklist to collect qualitative data from the sample of 3 (three) students. Through this study it was discovered on how learners who were blind remembered their academic work and this was through the use of internet, voice recorder, mobile phones and laptops with speech output, the use of group discussions and ordering of the work according to topics and subtopics. The study also revealed what helped the blind to remember their academic work and this was done through  attending of lectures, recording of lectures, writing of notes, dictation by lecturers, practical examples given by lecturers during lecture hours, by being given summarized notes by lecturers, help from sighted students and the use of braille and use of their braille equipment. The study further found two most important things which helped learners who were blind remember academic skills, concepts and information being taught and these were done though hearing and listening attentively and it was aided by neural plasticity.

El objetivo de la presente investigación es analizar la relación que existe entre la divulgación voluntaria de capital intelectual y la rentabilidad de las empresas no financieras que cotizaron en la Bolsa Mexicana de Valores durante el periodo 2018-2019. Se consideró como hipótesis central que la divulgación voluntaria de capital intelectual está relacionada de manera positiva con la rentabilidad de las empresas mexicanas que participan en el mercado de capitales. La metodología utilizada es descriptiva y explicativa por medio de un análisis multivariado, a través, del método de regresión lineal, estudiando la relación de dependencia entre las variables. Los resultados obtenidos muestran que la divulgación voluntaria de capital intelectual genera una influencia positiva y significativa en las variables de rentabilidad ROA y ROE, no siendo así, con la QTOBIN, debido a que no genera una influencia significativa. Los resultados obtenidos permiten concluir que las grandes empresas mexicanas adaptaron la forma en la que se comunican con sus partes interesadas para poder explotar un recurso tan fundamental como su capital intelectual y este cambio les generó beneficios positivos.
Impact of the COVID-19 pandemic on the online educational quality in USC’s school of engineering and school of cinematic art
Authors: Zhang Jiling
Published: February 2022

This research paper demonstrates the results of a questionnaire containing a series of questions, conducted at the University of Southern California, on the educational quality via online forms during the COVID-19 pandemic. The research was conducted with students from the School of Engineering and the School of Cinematic Arts. The outcome of the survey demonstrates that almost all of college students are pleased with the university's measures during the pandemic. But, negative perspectives were also reported: such as the shortage of adequate infrastructure for students and the shortage of effective communication and interaction between teachers and students, inability to make practical applications, shortage of socialization, shortage of motivation to learn, less objective exams (e.g., potential for cheating), potential for physical and mental health deterioration, and potential for health deterioration (e.g., spending too much time on online platforms, developing another lifestyle. Therefore, the university administration must take effective and efficient measures to eliminate the impact on students in the upcoming academic year. The university administration must take effective measures to eliminate these negative issues in order to improve the performance of the online education process. Improving the performance of the online education process.

Authors: Gregorio Mr. Jeanel C
Published: February 2022

The pandemic has challenged the educational system to alter the delivery of instruction from the traditional face-to-face into distant learning, modular and online. This sudden paradigm shift posited a lot of concerns particularly in the integration of technology in social studies curriculum. This review used the systematic literature review to analyze the empirical literature and the reading log (University of South Australia) to analyze the findings. The systematic literature is a rigorous approach in searching related literature, identifying publications to be included to undergo an iterative and transparent processes, analyze the data through a structured abstraction and a systematic approach (Gentles, S.J. et. al. 2016). This review found out that there is a limited literature in the integration of technology specific in social studies both internationally and in the Philippine context. Although there are some literature on technology integration in social studies, they failed to tackle the experiences and challenges by the teachers in technological integration in full online delivery of instruction specific in social studies teaching. Thus, it is recommended that researchers must explore other angles of technological integration in social studies such as the teacher’s perceptions of specific technologies used in the subject. Second, the experiences and challenges they encountered during the delivery of instruction amidst the crisis. Third, studies should also be conducted on the effect of technology integration to student outcomes. These studies will serve as the basis for the future planning, design, implementation, assessment, and modification of social studies curriculum to be more student centered, contextualized and inclusive with the use or aid of technologies.

The wounds were assessed according to Wagner wound staging and wound sepsis was evaluated in terms of local infection of the wound, leukocytosis and osteomyelitis of the bone. The glycemic control of these patients was assessed on presentation by measuring glaciated hemoglobin levels. Data was analyzed using SPSS 22.

Findings: Out Of the 450 patients, 263(60%) were males and 187(40%) were females. Majority patients 193(43%) were aged 40-70 years. All 450(100%) patients underwent some type of amputation. Of all the amputations, 301(67%) were done in patients with poor glycaemic control on presentation, and 187(41%) in those with stage 4 wound. Local wound infection, increased total leukocyte count and bone showing features of osteomyelitis were significantly associated with increased risk of lower extremity amputations (p<0.05).

Conclusion: With the proper glycemic control and early presentation and treatment, majority of amputations could be avoided in diabetic patients with foot ulcers.
