Authors: Nguyen Bao Quoc , Tran Duc Duy Tri , Dang Thuan Cong , Mai Thi Dang , Pham Hai Duong , Truong Van Tri 
Published: September 2021

Background:
Most spinal meningiomas primarily grow in the intradural extramedullary location. Epidural meningiomas are uncommon; if detected, they usually coexist with intradural lesions. They inhere more aggressive and invasive characteristics compared with their counterparts inside the dura.

Case Description:
We report a 22-year-old female who was admitted to the hospital with weakness and numbness in both lower limbs. Her cervical magnetic resonance imaging revealed an en-plaque and dumbbell-shaped lesion located from C5 to C8. After gadolinium injection, the whole mass was enhanced and unveiled two portions: intradural and extradural. The bone window of the computed tomography scan revealed calcification inside the lesion. The patient underwent tumor removal surgery. The pathology findings showed a psammomatous meningioma. After 6 months of surgery, the patient has been able to walk with walkers.

Conclusion:
We should consider spinal meningioma as a differential diagnosis when encountering an extradural lesion in the cervical region. The optimal surgical treatment for young patient with epidural meningiomas is radical surgery with dura attachment removal.

Purpose: This paper analyzes the determinants of technical efficiency of Islamic banks in eight of the Islamic countries. These include Brunei Darussalam, Jordan, Indonesia, Pakistan, Malaysia, Turkey, Saudi Arabia, and the UAE. Design/Methodology/Approach: A quarterly panel data on eight Islamic countries’ banks during the period of 2014 to 2019 is used for the analysis. Findings: The overall outcomes of the study indicate that banks in KSA, UAE, and Malaysia are found to be more efficient than their counterparts in other five countries in the sample. Banks from KSA and UAE have the same average technical efficiency scores while banks in Malaysia and Jordan tend to share similar average technical efficiency scores. Findings of the study reveal that variables like bank size, return on equity, and liquid asset ratio have a positive and significant bearing while factors like GDP growth rate, Z-score, and capital adequacy ratio have a negative and significant impact on technical efficiency of Islamic banks. Implications/Originality/Value: The study puts forward some useful policy implications both for managers of banks and policymakers of countries in the sample.

Biocorrosion is a phenomenon that strongly affects the integrity of the materials used in the oil and gas industry. Different types of biocides are currently used to control bacteria in industrial water; however, they have disadvantages such as microbial resistance to these chemical compounds and possible impact on biodiversity due to eventual contamination of natural water. There are several alternatives for the elimination or control of bacteria, among which one is the use of type C ultraviolet (UV-C) radiation. Nevertheless, the use of these micro-organism removal systems could be affected by water quality and its efficiency can be improved by using LED diodes of lower energy consumption and greater versatility in exposure to high temperatures. This work was aimed to evaluate the use of such radiation as a strategy for the control and/or elimination of sulfate reducing bacteria (SRB), and acid producing bacteria (APB) present in both corrosion and souring processes. For this purpose, injection water from oil and gas industry and a dynamic system which flow variation enabled the evaluation of different water exposure times to UV-C light (1-20 minutes) were used. Efficiencies ranging between 99-100% were achieved in the elimination of SRB and APB from produced water measured by two different techniques, selective culture media for these microbial populations, and qPCR detecting a specific gene from the SRB population.
Suitability assessment for electricity generation through renewable sources: towards sustainable energy production
Authors: Pérez-Denicia Eduardo , Fernández-Luqueño Fabián , Vilariño-Ayala Darnes 
Published: September 2021

Power generation through renewable sources is an effective alternative to mitigate climate change as its environmental impact is lower compared to fossil fuels. However, socio-economic problems are constant in sites where power plants are installed, especially in developing countries. In this paper, an innovative methodology was developed to assess the suitability of electricity generation through solar, wind, and biomass energy. Unlike most studies found in scientific literature, this work considers social, environmental, and economic aspects as key to determine the suitability of energy projects. First, we carried out a comprehensive analysis on social acceptance and resilience towards renewable energy and the conditions for communities to benefit from these projects; then, we analyzed the availability and capacity of renewable energy sources in Mexico, as a case study. Next, a set of indicators related to the three pillars of sustainability was developed to assess the conditions of each place with the best renewable resources in the country. The life cycle and capacity factor of each technology were also considered. Lastly, a mathematical model was developed to determine the most suitable locations and technologies for power generation. The results show a trend towards the states of northern Mexico, especially those bordering the United States, as the most viable for electricity generation. The most appropriate technology is wind energy. Finally, Oaxaca, the state with the best wind resources and current leader in wind power generation in Mexico is, by contrast, the least viable state for wind generation, as has been later confirmed by scientific evidence, as wind facilities are associated with severe socio-cultural and economic damage in host communities in this state.
THE “FLU SEASONS” AND THE MISSING DATA: A MATCHED-PAIR ANALYSIS FOR THE PANDEMIC SEASON 2019_2020
Authors: Kay Lo Ip Vincent 
Published: September 2021

The unit cell from the McNemar’s 2x2 Table denotes the week with col (1, 2) and the Public Health Region with Row (1, 2). We calculate the standard normal statistic (z) for A(H1), A(H3), Influenza B. Each one categorical unit is in fact a pair of matched-pair data within its own partial table. The Cochran-Mantel-Haenszel Test collapses these partial tables to summate these 2n observations in a 2x2 x n contingency table to yield the marginal counts of the McNemar’s test.
The open data for Europe/Asia began this SARS-CoV2 pandemic, from week 3 to week 14, with the normal statistic (z) entering into an identical collapse mode. These all assumed the same “V” curve as the general collapse pattern and they rippled together without overlapping. During this period China applied mandatory lockdown and they mandated masks. We should strive to be more evidence-based so that we can convince more of the general public to accept the public health measures to survive.

Published: September 2021

Introduction: Transconjunctival micro incision vitrectomy surgery (MIVS) with 23 or 25 gauge instrumentation is more advantageous than traditional 20 gauge surgery. We intended to evaluate the visual outcome, complications and indication of various vitreoretinal diseases using 27 Gauge vitrectomy systems.
Methods: This study was a prospective, interventional, non-comparative study conducted in Nepal Eye Hospital from June 2017 to July 2018. Fifty-two patients with various vitreoretinal diseases were recruited. The main outcome measures included corrected distance visual acuity (CDVA) preoperative and postoperative, intraocular pressure (IOP) preoperative and postoperative, indication for vitreoretinal surgery, intraoperative complications, and postoperative complications.
Results: Fifty two eyes of 52 patients (26 men and 26 women; mean age, 59 years) underwent 27-gauge pars planavitrectomy. Surgical indications included epiretinal membrane (n = 11), full-thickness macular hole (n = 11), rhegmatogenous retinal detachment [n = 14 (12 vitrectomy only and two vitrectomy with scleral buckle)], vitreous haemorrhage (n = 3), vitreous opacities (n = 3), silicon oil removal (n = 3), proliferative diabetic retinopathy [n = 6 (5 vitreous haemorrhage and one tractional retinal detachment)], posterior IOL dislocation (n = 1). Postoperative complications included transient ocular hypertension in eight eyes (15.39%), transient hypotony in five eyes (9.62%) and vitreous haemorrhage in five eyes (9.62%). No cases of postoperative endophthalmitis, sclerotomy - related tears, or choroidal detachments were encountered in the follow-up period. Mean corrected distance visual acuity improved from 20 / 796 (logarithm of the minimum angle of resolution, 1.60 ± 0.64) preoperatively to 20 / 49 (logarithm of the minimum angle of resolution, 0.42 ± 0.26) postoperatively (p = 0.000,) at final follow up.
Conclusions: 27-gauge micro-incision vitrectomy surgery was found to be a safe and effective suture-less surgery with favourable outcomes, in terms of vision.

Published: September 2021

Introduction: Antibiotic resistance has been described by World Health Organisation as a major global health problem that threats our ability to treat common infectious diseases and needs urgent action. Among many other factors, knowledge and behaviour of community members that lead to inappropriate use of antibiotic highly contributes to development and spread of antimicrobial resistance. Hence this study has been undertaken with the aim to assess the knowledge and attitude related to antibiotic use among high school students.
Methods: A cross-sectional questionnaire based survey was conducted at a Kathmandu based high-school. The data were collected via self-administered questionnaire after verbal consent for voluntary participation. There were nine questions related to knowledge and five questions related to attitude. Data were aggregated to compile frequency distribution tables and the percentages of responses were calculated.
Result: A total of 232 students participated in the study. In the questions related to knowledge, nearly 62% of the students agreed to the statement “Antibiotics are needed to cure most coughs and cold”. About 19% students were not sure whether antibiotics can kill the useful bacteria in our body. In the attitude part, 53.87% students responded that they stop taking antibiotics when they start to feel better and 59.91% students responded that they buy antibiotics on their own from a pharmacist when needed.
Conclusions: The deficiencies in basic understanding about the nature and use of antibiotics and casual attitude in their use among high school students is a matter of great concern as it poses many serious problems including promotion of antibiotic resistance
Clinical significance of Catheter-Associated Urinary Tract Infection (CAUTI) in Intensive Care Units: Three Year Experience at a Single Centre
Authors: Basukala Sunil , Yadav Punit , Chatterjee Arinidam , Ranyal Rakesh kumar , Baidya Manish 
Published: September 2021

Introduction: Catheter Acquired Urinary Tract Infection (CAUTI) is one of the most common Health Care Acquired Infections (HCAI); most of these infections are attributable to use of an indwelling urethral catheter. The aim of this study was to investigate patients with catheter-associated urinary tract infection over three years at a single hospital’s Intensive Care Unit (ICU) and to identify meaningful risk factors and causative organisms.
Methods: A retrograde analysis was performed on patients with indwelling catheters in ICU of Armed Forces Medical College, Pune, India. CAUTI was defined as isolated bacterial growth of 100,000 colony-forming units or more either 48 hours after transfer to the ICU if a urinary catheter was placed before the transfer or 48 hours after insertion if the catheter was inserted in the ICU. Only the patients whose culture results were negative before ICU admission were included.
Result: Among 350 samples collected in medical and surgical ICU, 38 patients (10.85%) had CAUTI. Using multivariate logistic regression analysis, the study showed that those with diabetes were 4.51 (p＜0.001) times likely to have occurrences of CAUTI than those without and also showed an increased incidence of CAUTI > 1.19 fold (p＜0.01) among patient with longer duration of an indwelling catheter.
Conclusions: CAUTI is a preventable HCAI and thus the risk factors and causative organisms contributing to its development in the management of ICU patients must be considered to prevent the occurrence of UTIs in this setting.
