Published: March 2022

During the COVID-19 pandemic, the application of e-payment has rapidly increased. However, e-payment has not been able to achieve a trustworthy level in e-commerce transactions. Thus, cash payment methods with Cash On Delivery (COD) services still dominate C2C e-commerce payment transactions in Indonesia. This study aims to investigate factors that affect users' switching intentions from COD to e-payment services. The research model was adopted by using the Push-Pull-Mooring framework, integrating perceived COVID-19 risk, technology acceptance, and transaction effort. Empirical research was conducted using data from 546 COD and e-payment users in Indonesia, with Structural Equation Modelling (SEM) being used to validate the model and analyze the hypotheses. The results indicate that switching intention from COD to e-payment is significantly influenced by pull factors in e-payment, which are economic benefits, performance expectancy, effort expectancy, and critical mass. There are also two mooring factors that significantly influence the switching intention from COD to e-payment, which are trust and perceived security and privacy. This study makes a significant contribution to the literature in terms of validating a theoretical framework that emphasizes factors that influence user switching intentions from COD to e-payment in the context of the COVID-19 pandemic. This research can be a reference for Indonesian payment system regulators and e-payment service providers in formulating regulations and strategies to accelerate the spread of digital transactions in Indonesia.

Authors: Tien Nguyen Van 
Published: March 2022

In Vietnam, the Covid-19 pandemic has taken place since the beginning of 2020, has seriously impacted businesses' production and business activities, and pushed the world economy into recession. Like other countries globally, Vietnam has been severely affected by this global pandemic. During the Covid-19 outbreak, small and medium enterprises (SMEs) that stopped production or went bankrupt increased. Besides, due to the deep integration into the global value chain now closed to the port, the findings explored that SMEs with a larger scale faced many difficulties. The number of enterprises having to shrink production also increased rapidly. Most businesses say the Covid-19 outbreak has negatively affected their production and trade. The primary official data is distributed directly to business leaders through detailed questionnaires to collect preliminary data and selected models by a simple random process. SMEs failed to reach customers, broke the supply chain, revenue plummeted, and laid off many workers, so far struggling. The study objectives found that more than 87% of businesses are affected by Covid-19. Therefore, the article novelty had several recommendations for enhancing the competitive capacity of small and medium enterprises in Vietnam after the Covid-19 pandemic.

Authors: Zulkifliani Zulkifliani , Usman Usman 
Published: March 2022

Ammonium chloride is one of the biocides used to reduce viability of bacterial cells in produced water from oil wells that will be applied as injection water. The advantage of this biocide is having high epication penetrate the cell wall, causing death of bacteria cells (bacteriocidal). Tests for antibacterial activity was done by using the API RP-38 method by adding ammonium chloride into the produced water to obtain the final concentrations of 4, 8, 16, 32, 64, and 128 mg/L. Laboratory test results showed that giving ammonium chloride at a concentration of 64 mg/L can significantly reduced the viability of bacterial cells, including groups of aerobic and anaerobic bacteria.

A jabuticaba (Myrciaria ssp) é bem conhecida por possuir em sua casca compostos fenólicos com alta atividade antioxidante. Assim, este estudo objetivou avaliar efeitos antioxidantes em fígado e cérebro e antimutagênicos na medula óssea de camundongos Swiss machos com o extrato aquoso de jabuticaba (MYR) e como agente indutor de danos mutagênicos a ciclofosfamida (CPA). Foram analisados 4 grupos (N = 6): Controle (C), CPA (25 mg.kg-1), Extrato aquoso de jabuticaba + CPA (MYR + CPA) e Extrato aquoso de jabuticaba (MYR). Através do teste do micronúcleo em células de medula óssea avaliou-se a frequência de micronúcleos em eritrócitos policromáticos para a atividade antimutagênica/mutagênica. Os parâmetros bioquímicos avaliados foram: Superóxido dismutase (SOD), Catalase (CAT), Glutationa-S-transferase (GST), Glutationa reduzida (GSH), Ácido Ascórbico (VIT C) e Carbonil. Os resultados obtidos mostraram que o extrato aquoso da jabuticaba não teve efeito antimutagênico, bem como mutagênico. A Vit C aumentou no tecido hepático no grupo MYR quando comparada ao grupo MYR + CPA. Conclui-se que, nas condições experimentais utilizadas, o extrato da jabuticaba não apresentou potencial protetor aos danos induzidos pela CPA, nem modificou de forma relevante os parâmetros do estresse oxidativo nos animais tratados com MYR.

Analysis of jabuticaba aqueous extract against redox status
and mutageness in mice

ABSTRACT: Jabuticaba (Myrciaria ssp) is well known for having in its bark phenolic compounds with high antioxidant activity. Thus, this study aimed to evaluate antioxidant effects in the liver and brain and antimutagenic effects in the bone marrow of male Swiss mice with the aqueous extract of jabuticaba (MYR) and as a mutagenic damage-inducing agent to cyclophosphamide (CPA). Four groups were analyzed (N = 6): Control (C), CPA (25 mg.kg-1), Aqueous jabuticaba extract + CPA (MYR + CPA) and Aqueous jabuticaba extract (MYR). Through the micronucleus test in bone marrow cells, the frequency of micronuclei in polychromatic erythrocytes was evaluated for antimutagenic/mutagenic activity. The biochemical parameters evaluated were: Superoxide dismutase (SOD), Catalase (CAT), Glutathione-S-transferase (GST), Reduced Glutathione (GSH), Ascorbic Acid (VIT C) and Carbonyl. The results obtained showed that the aqueous extract of jabuticaba did not have an antimutagenic or mutagenic effect. Vit C increased in liver tissue in the MYR group when compared to the MYR + CPA group. It is concluded that, under the experimental conditions used, the jabuticaba extract did not show protective potential against damage induced by CPA, nor did it significantly modify the parameters of oxidative stress in animals treated with MYR.

Authors: Okuda Tomohiro , Nishimura Ataru , Arimura Koichi , Iwaki Katsuma , Fujino Takeo , Ushijima Tomoki , Sonoda Hiromichi , Tanoue Yoshihisa , Shiose Akira , Yoshimoto Koji 
Published: March 2022

BACKGROUND
Cerebrovascular events and infection are among the most common complications of left ventricular assist device (LVAD) therapy. The authors reported on a patient with an infectious intracranial aneurysm (IIA) associated with LVAD infection that was successfully occluded by endovascular therapy.

OBSERVATIONS
A 37-year-old man with severe heart failure received an implantable LVAD. He was diagnosed with candidemia due to driveline infection 44 months after LVAD implantation, and empirical antibiotic therapy was started. After 4 days of antibiotic treatment, the patient experienced sudden dizziness. Computed tomography (CT) revealed subarachnoid hemorrhage in the right frontal lobe, and CT angiography revealed multiple aneurysms in the peripheral lesion of the anterior cerebral artery (ACA) and middle cerebral artery. Two weeks and 4 days after the first bleeding, aneurysms on the ACA reruptured. Each aneurysm was treated with endovascular embolization using n-butyl cyanoacrylate. Subsequently, the patient had no rebleeding of IIAs. The LVAD was replaced, and bloodstream infection was controlled. He received a heart transplant and was independent 2 years after the heart transplant.

LESSONS
LVAD-associated IIAs have high mortality and an increased risk of surgical complications. However, endovascular obliteration may be safe and thus improve prognosis.
Catastrophic delayed cervical arthroplasty failure: illustrative case
Authors: Carrera Diego A. , Ricks Christian B. 
Published: March 2022

BACKGROUND
Cervical disc replacement (CDR) is an increasingly used alternative to fusion for symptomatic cervical disc disease. While more studies have suggested favorability of CDR over fusion procedures, limited data exist regarding implant fatigability. Here, the authors present a unique and previously unreported failure of the M6-C prosthesis causing spinal cord injury.

OBSERVATIONS
A 49-year-old female with history of cervical degenerative disease and prior C4–7 M6-C arthroplasty presented 9 years later after a minor fall from standing. She endorsed bilateral hand numbness ascending to forearms and shoulders, with dysesthesias and weakness. Imaging showed fractured arthroplasty penetrating the spinal cord. Revision surgery found a ruptured arthroplasty annulus with metal piece piercing the spinal cord. Partial C4 and C5 corpectomy was performed to remove the integrated fins of the arthroplasty and inspect the cord and dura. This was reconstructed with a corpectomy cage and plate. The patient made an excellent recovery, with improvement in her weakness and resolution of her sensory symptoms.

LESSONS
Possibility of fatigue-related failures presenting years after implantation have only been infrequently reported but can be catastrophic for patients. The authors encourage further discussions in this area, increased counseling with patients, and recommend a patient registry to better document adverse events.

Authors: Hakim Jonaed , Jahan Afrina , Choudhury MKI Quayyum , Zawad M , Mollah Rayhan Ali 
Published: March 2022

Background & objective: Intertrochanteric fractures are becoming increasingly common as our population ages. These fractures typically occur in frail patients with multiple comorbidities The morbidity associated with the fracture can be minimized by choosing appropriate fixation device for the fracture pattern, recognizing the stability of fixation, and performing accurate reduction with ideal implant placement. So, these fractures should be treated expeditiously so that there are minimum fixation failures. In BIRDEM hospital a large number of elderly patients having intertrochanteric femur fractures with multiple comorbidities, are treated by primary hemiarthroplasty. The purpose of this study is to see the clinical outcome of these hemiarthroplasty patients.
Methods: This retrospective study was carried out over four years from 2015 to 2019 on 60 patients (42 females and 18 males). All patients had diabetes in common along with other co-morbidities like ischaemic heart disease, hypertension, chronic kidney disease and stroke. The outcome was evaluated by applying Harris Hip Score after intervention.
Result: The mean age of the patients was 65.5 years (range: 60-85 years) with male to female ration being 3:7. The mean Harris Hip score at the four-year follow-up was 83.1 ± 10.9. A total of 12(20%) patients were graded as excellent, 30(50%) patients as good, 15(25%) as fair and 3(5%) as poor. It was observed that, patients with AO (Arbeitsgemeinschaft für Osteosynthesefragen) type 31A1 intertrochanteric fractures had better outcome than AO type 31A2 and 31A3 in our study.
Conclusion: Primary hemiarthroplasty can provide a stable, pain-free, mobile joint with acceptable complication rates. These fractures must be treated considering patient’s age, bone quality and type of the fracture.

Authors: Naznin Farhana , Jesmin Shahela , Akter Nurjahan , Sharmin Susmita , Khatun Mst Rokeya 
Published: March 2022

Background & objective: Although the role of vitamin-D in calcium metabolism and bone health is undisputed, other long-term health consequences of low vitamin-D are still debated. Observational studies have recently indicated that vitamin-D deficiency may be a modifiable risk factor for gestational diabetes mellitus (GDM), although several experimental studies have failed to establish such an association. The present study was undertaken to test the hypothesis that vitamin-D insufficiency or deficiency is associated with GDM.
Methods: The present case-control study was conducted in the Department of Obstetrics and Gynaecology, Rajshahi Medical College (RMC), Rajshahi, Bangladesh, over a period of 1 year between July 2019 to June 2020. Patients with confirmed GDM (case) and normal pregnant women (control) attending in the above-mentioned place during the study period were the study population. A total of 18 cases and 54 controls were consecutively included in the study based on predefined eligibility criteria. The exposure and outcome variables were serum vitamin-D insufficiency/deficiency and GDM respectively. Vitamin D insufficiency was considered when serum level 25(OH)D ranges from ≥ 15 to < 30 ng/ml and deficiency was termed if 25(OH)D level lies below 15 ng/ml. Crosstab analysis with Odds Ratio (OR) was done to find the association between vitamin-D and GDM and the risk of developing the outcome (GDM) due to vitamin-D insufficiency or deficiency.
Result: In the present study age, residence, socioeconomic status and season at data collection were almost identically distributed between case and control groups. However, the study demonstrated occupation, pre-pregnancy obesity, family history of type-II diabetes, polyhydramnios, level of hemoglobin and serum vitamin-D insufficiency/deficiency to be associated with GDM. Majority (83.3%) of the GDM patients had insufficient or deficient serum vitamin D level (< 30 ng/mL) as compared to 57.4% of the control group. The risk of having GDM in pregnant women with insufficient or deficient serum vitamin-D was estimated to be almost 4-fold (95% CI = 1.1 – 14.3) higher (p = 0.047) than that in the pregnant women with normal serum vitamin-D level.
Conclusion: The study concluded that pregnant women with GDM are associated with insufficient or deficient serum vitamin-D with risk of having GDM in pregnant women with insufficient or deficient serum vitamin-D is much greater than the pregnant women with normal serum vitamin-D level.

Comparative Study on Serum Hepatic Enzymes between Normal Healthy Adults and Obese People of Rajshahi City
Authors: Rashed Md Rakib , Jhumu Sumayra , Zaman Tania Sultana , Khatun Mst Fatema 
Published: March 2022

Background & objective: Obesity is rapidly emerging as one of the major causes of non-alcoholic fatty liver disease (NAFLD), the early sign of which is elevated liver enzymes. But very few studies have yet been done in our country to find the association between overweight and obesity and levels of serum hepatic enzymes. The present study was undertaken to determine the association between overweight/obesity determined by body mass index (BMI) and serum hepatic enzymes.
Methods: This cross-sectional analytical study was conducted in the Department of Physiology, Rajshahi Medical College, Rajshahi over a period of one year between July 2018 to June 2019 in collaboration with the Department of Biochemistry of the same Medical College. Based on certain predefined enrolment criteria, 33 overweight or obese (BMI ≥23 kg/m2) individuals (case) and 33 sex-matched apparently healthy adults (BMI <23 kg/m2) (control) were included from the Rajshahi City. All the study subjects were then tested for serum hepatic enzymes (ALT, AST, ALP and GGT). The investigation findings obtained were compared between case and control groups.
Result: The mean ages of the cases and controls were almost similar (31.1 and 29.4 years respectively, p = 0.576).All the serum hepatic enzymes but GGT were found to be significantly raised in the case group than those in the control group. The BMI was found to bear significantly linear relationship with serum ALT, AST and ALP (r = 0.709, p < 0.001, r = 0.718, p < 0.001 and r = 0.545, p < 0.001 respectively) indicating that more than 70% of the variations in ALT and AST and 55% of the variations in ALP might be due to variation in BMI. When waist circumference was correlated with hepatic enzymes, it was found to correlate better than the BMI did with 70.3% of the variations in ALT, 77.2% of variations in AST and 57.4% variation in ALP being explained by waist circumference. However, WHR did not correlate well with hepatic enzymes. AST alone bears a weekly significant correlation with WHR, with only 28% of the variations in AST could be explained by WHR.
Conclusion: The study concluded that all the serum hepatic enzymes but GGT are significantly raised in the overweight and obese individuals than those in individuals with normal BMI. The BMI bears significantly linear relationships with serum ALT, AST and ALP. A substantial proportion of the variations in ALT and AST could be explained by BMI. Waist circumference correlates even better than the BMI does. However, WHR is not a good predictor of serum hepatic enzymes.
