Authors: Darwin Darwin , Budiyanta Nova Eka 
Published: February 2022

ABSTRACT:Laboratories in university are one of the most essential facilities needed for academic activities. However, because of the Covid-19 pandemic, there is now restriction to access university laboratories. Students have lost their access to laboratory equipment. Based on this problem, a web application for equipment booking and laboratory asset management is made. The web application uses RFID technology with NodeMCU ESP8266 as its microcontroller, and CodeIgniter 4 framework. The web application is evaluated by feature validation by the laboratory assistant head, white-box test and black-box test. White-box test uses Apache JMeter 5.3 to do load testing. The black-box test produces a functionality percentage of 82%, and from the white-box and feature validation we can conclude that the web application works well and is ready to be used.ABSTRAK:Laboratorium universitas merupakan salah satu fasilitas yang penting dalam kegiatan akademik.

e-Learning in Medical Education in Sri Lanka: Survey of Medical Undergraduates and New Graduates
Authors: Samarasekara Keshinie 
Published: February 2022

Background
Medical education has undergone drastic changes with the advent of novel technologies that enable e-learning. Medical students are increasingly using e-learning methods, and universities have incorporated them into their curricula.

Objective
This study aimed at delineating the pattern of use of e-learning methods among medical undergraduates and new graduates of the Faculty of Medicine, University of Colombo, and identifying the challenges faced by these students in using e-learning methods.

Methods
A cross-sectional descriptive study was conducted in the Faculty of Medicine, University of Colombo, in April 2020, with the participation of current undergraduates and pre-intern medical graduates, using a self-administered questionnaire that collected data on sociodemographic details, pattern of use of learning methods, and challenges faced using e-learning methods.

Results
There were 778 respondents, with a response rate of 65.1% (778/1195). All the study participants used e-learning resources with varying frequencies, and all of them had at least 1 smart device with access to the internet. Electronic versions of standard textbooks (e-books), nonmedical websites, online lectures, medical websites, and medical phone apps were used by the majority. When comparing the extent of use of different learning methods, it appeared that students preferentially used traditional learning methods. The preference was influenced by the year of study and family income. The 3 most commonly used modalities for learning new study material and revising previously learned content were notes on paper material, textbooks (paper version), and e-books. The majority (98.7% [n=768]) of participants have encountered problems using e-learning resources. The most commonly faced problems were unavailability of free-of-charge access to some e-learning methods, expenses related to internet connection, poor connectivity of mobile internet, distractions while using online resources, and lack of storage space on electronic devices.

Conclusions
There is a high uptake of e-learning methods among Sri Lankan medical students. However, when comparing the extent of use of different learning methods, it appeared that students preferentially used traditional learning methods. A majority of the students have encountered problems when using e-learning methods, and most of these problems were related to poor economic status. Universities should take these factors into consideration when developing curricula in medical education.
Cancer Screening Recommendations During the COVID-19 Pandemic: Scoping Review
Authors: Shah Sumit K , McElfish Pearl A 
Published: February 2022

Background
Cancer screening tests are recommended to prevent cancer-associated mortality by detecting precancerous and cancerous lesions in early stages. The COVID-19 pandemic disrupted the use of preventive health care services. Although there was an increase in the number of cancer screening tests beginning in late 2020, screenings remained 29% to 36% lower than in the prepandemic era.

Objective
The aim of this review is to assist health care providers in identifying approaches for prioritizing patients and increasing breast, cervical, and colorectal cancer screening during the uncertainty of the COVID-19 pandemic.

Methods
We used the scoping review framework to identify articles on PubMed and EBSCO databases. A total of 403 articles were identified, and 23 articles were selected for this review. The literature review ranged from January 1, 2020, to September 30, 2021.

Results
The articles included two primary categories of recommendations: (1) risk stratification and triage to prioritize screenings and (2) alternative methods to conduct cancer screenings. Risk stratification and triage recommendations focused on prioritizing high-risk patients with an abnormal or suspicious result on the previous screening test, patients in certain age groups and sex, patients with a personal medical or family cancer history, patients that are currently symptomatic, and patients that are predisposed to hereditary cancers and cancer-causing mutations. Other recommended strategies included identifying areas facing the most disparities, creating algorithms and using artificial intelligence to create cancer risk scores, leveraging in-person visits to assess cancer risk, and providing the option of open access screenings where patients can schedule screenings and can be assigned a priority category by health care staff. Some recommended using telemedicine to categorize patients and determine screening eligibility for patients with new complaints. Several articles noted the importance of implementing preventive measures such as COVID-19 screening prior to the procedures, maintaining hygiene measures, and social distancing in waiting rooms. Alternative screening methods that do not require an in-person clinic visit and can effectively screen patients for cancers included mailing self-collection sampling kits for cervical and colorectal cancers, and implementing or expanding mobile screening units.

Conclusions
Although the COVID-19 pandemic had devastating effects on population health globally, it could be an opportunity to adapt and evolve cancer screening methods. Disruption often creates innovation, and focus on alternative methods for cancer screenings may help reach rural and underresourced areas after the pandemic has ended.
The Impact of COVID-19 Pandemic on Health Care-Associated Infections in Intensive Care Units: Results From the Egypt National Health Care-Associated Infections Surveillance, 2019-2020
Authors: Roshdy Essam Mostafa , Attia Ehab , Samy Sahar , Afifi Salma , Abuelsood Hanaa , BahaaEldin Hala , Aied Alaa , Abdelfattah Mohammad 
Published: February 2022

Background
The COVID-19 pandemic resulted in the unexpected influx of patients leading to high rates of hospitalization. Focusing resources to mitigate the pandemic unintentionally reduced attention to health care-associated infections (HAIs) prevention programs. Intensive care units (ICUs) have suffered the most burden due to requirement of ventilation.

Objective
In this paper, we aimed to estimate the national HAI rates at ICUs before and during the COVID-19 pandemic to better identify the pandemic’s impact on HAIs.

Methods
Egypt’s HAI Surveillance was established in 2016 in 177 governmental ICUs. CDC case definitions and questionnaire were used to collect patients’ data. The types of HAIs targeted included bloodstream infections, pneumonia, and urinary tract infections. Pathogen identification and antimicrobial resistance were performed at the central laboratory. Surveillance data 2019-2020 were obtained, and a descriptive data analysis was performed. HAI rates per 100 patient days and device-associated infections (DAIs) per 1000 device days were compared between 2019 and 2020.

Results
In 2020, 4028 HAIs were reported, including 777 (19.3%) ICU-acquired reports; however, in 2019, 6242 were reported, including 1084 (17.4%) ICU-acquired ones. Incidence significantly decreased in 2020 compared with 2019 (2.67 vs 2.72, P<.001). The percentages of bloodstream infections, pneumonia, and urinary tract infection in 2020, compared with 2019, were 64.0% versus 61.6%, 10.9% versus 12.1%, and 25.1% versus 23.8%, respectively. DAIs decreased significantly, including CLABSI (2.6 vs 2.5, P<.001), VAP (0.75 vs 0.87, P=.04), and CAUTI (1.5 vs 1.6, P=.02). Klebsiella spp. was the predominant pathogen in both years representing (35.6% and 38.1%), followed by S. aureus (11.2% and 15.4%). The rate of carbapenem-resistant K. pneumoniae insignificantly increased (25% vs 23%, P=0.3), and that of Methicillin-resistant S. aureus decreased (68% vs 70%, P=0.4).

Conclusions
Egypt’s HAI Surveillance successfully described the impact of COVID-19 pandemic on HAIs. It identified a significant decrease in ICU-acquired HAIs and DAIs at the first pandemic year, which could reflect better the infection control measures. The types of HAIs, causative pathogens, and antimicrobial resistance pattern did not change significantly. Surveillance should be maintained to guide HAIs’ preventive and control measures.

Authors: El Karoui Khalil , Hourmant Maryvonne , Ayav Carole , Glowacki François , Couchoud Cécile , Lapidus Nathanaël ,   on behalf of the REIN Registry
Published: February 2022

Background and objectives
Dialysis patients have a high mortality risk after coronavirus disease 2019 (COVID-19) and an altered immunologic response to vaccines, but vaccine clinical effectiveness remains unknown in this population.

Design, setting, participants, & measurements
Using Bayesian multivariable spatiotemporal models, we estimated the association between vaccine exposure and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) severe infections (with hospital admission) in dialysis patients from simultaneous incidence in the general population. For dialysis patients, cases were reported within the French end-stage kidney disease REIN registry from March 11, 2020, to April 29, 2021, and vaccine exposure (first dose) was reported in weekly national surveys since January 2021. Cases in the general population were obtained from the national exhaustive inpatient surveillance system (SI-VIC database), and vaccination coverage (first dose) was obtained from the national surveillance system (VAC-SI database).

Results
During the first wave, incidence in dialysis patients was approximately proportional to the general population. However, we showed a lower relative incidence for dialysis patients during the second wave (compared with that observed in nondialysis patients), suggesting an effect of prevention measures. Moreover, from the beginning of the vaccination rollout, incidence in dialysis patients was lower compared with predictions based on the first and second waves. Adding vaccination coverages in dialysis and nondialysis patients as predictors allowed the reported cases to be fit correctly (3685 predicted cases, 95% confidence interval, 3552 to 3816, versus 3620 reported). Incidence rate ratios were 0.37 (95% confidence interval, 0.18 to 0.71) for vaccine exposure in dialysis patients and 0.50 (95% confidence interval, 0.40 to 0.61) per 10% higher in vaccination coverage in the same-age general population, meaning that vaccine exposure in dialysis patients and the general population was independently associated with lower hospitalization rate of dialysis patients.

Conclusions
Our findings suggest that vaccination may yield a protective effect against severe forms of COVID-19 in dialysis patients, despite altered immunologic vaccine responses.

Published: February 2022

Background and objectives
Although most patients receiving maintenance dialysis exhibit initial seroresponse to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination, concerns exist regarding the durability of this antibody response. This study evaluated seroresponse over time.

Design, setting, participants, & measurements
This retrospective cohort study included patients on maintenance dialysis, from a midsize national dialysis provider, who received a complete SARS-CoV-2 vaccine series and had at least one antibody titer checked after full vaccination. IgG spike antibodies (anti-spike IgG) titers were assessed monthly with routine laboratory tests after vaccination; the semiquantitative assay reported a range between zero and ≥20 Index. Descriptive analyses compared trends over time by history of coronavirus disease 2019 (COVID-19) and vaccine type. Time-to-event analyses examined the outcome of loss of seroresponse (anti-spike IgG <1 Index or development of COVID-19). Cox regression adjusted for additional clinical characteristics.

Results
Among 1870 patients receiving maintenance dialysis, 1569 had no prior COVID-19. Patients without prior COVID-19 had declining titers over time. Among 443 recipients of BNT162b2 (Pfizer), median (interquartile range) anti-spike IgG titer declined from ≥20 (5.89 to ≥20) in month 1 after full vaccination to 1.96 (0.60–5.88) by month 6. Among 778 recipients of mRNA-1273 (Moderna), anti-spike IgG titer declined from ≥20 (interquartile range, ≥20 to ≥20) in month 1 to 7.99 (2.61 to ≥20) by month 6. The 348 recipients of Ad26.COV2.S (Janssen) had a lower titer response than recipients of an mRNA vaccine over all time periods. In time-to-event analyses, recipients of Ad26.COV2.S and mRNA-1273 had the shortest and longest time to loss of seroresponse, respectively. The maximum titer reached in the first 2 months after full vaccination was associated with durability of the anti-spike IgG seroresponse; patients with anti-spike IgG titer 1–19.99 had a shorter time to loss of seroresponse compared with patients with anti-spike IgG titer ≥20 (hazard ratio, 15.5; 95% confidence interval, 11.7 to 20.7).

Conclusions
Among patients receiving maintenance dialysis, vaccine-induced seroresponse wanes over time across vaccine types. Early titers after full vaccination are associated with the durability of seroresponse.

Authors: Carrero Delgado Wilder Andrés 
Published: February 2022

Este artículo propone revisitar los memoriales como fuente para el estudio de las colonizaciones y conflictos agrarios durante el siglo xix y xx. Para tal fin, se considera que esta fuente no debe leerse únicamente como medio de denuncia ante el gobierno o autoridad judicial, sino más bien, como instrumento de acción política con alcances y limitaciones dadas por la estructura administrativa del Estado. Metodológicamente, el artículo se divide en tres partes: en la primera, se presentan los antecedentes y alcances jurídico-políticos de los memoriales para la sociedad del siglo xix y comienzos del xx; posteriormente, se caracterizan los documentos a partir de la descripción de su estructura interna, para lo cual se utilizan algunos casos identificados en el Archivo General de la Nación y archivos locales; y finalmente, se cierra con las conclusiones y proposiciones sobre cómo aprovechar los memoriales y los distintos retos de interpretación histórica dispuestos para quienes deseen estudiar los conflictos agrarios.
The Effect of Privatization on the Performance of Employees A case study on Karachi Electric Supply Company
Authors: Dad Malik 
Published: February 2022

Karachi Electric Supply Company (K.E.S.C.) is one of the most recently privatized companies in Pakistan. Since its privatization in 2005, it has been in the phase of bringing about many changes; re-branding and revitalizing with the introduction of new concepts such as integrated business centers (IBCs), which are one window solution for customers. K.E.S.C. has come up with new business strategies and a customer-oriented outlook with greater emphasis on employee performance.
The objective of this research was to investigate the effects of privatization on the employee performance of Karachi Electric Supply Company (K.E.S.C) and find out the changes in the overall employee performance. For this purpose, research was conducted from the employees of K.E.S.C. The variables identified through the literature review were commitment, organizational change, communication, training and development, financial benefits, and job security. The research aimed at finding out what changes have been taken place in these factors after privatization and what were the impacts of those changes on the overall performance of the employees.
In order to investigate the variables, a detailed study was carried out. Both; employees and the employers’ perspectives regarding the performance changes were investigated. For this purpose, employees belonging to the middle-level management of K.E.S.C. working at IBC’s since the pre-privatization era was chosen, as the major change was implemented in these units of K.E.S.C. primarily.
Apart from surveys, 3 interviews of management working at integrated business units of K.E.S.C. were also conducted as they have direct interaction with the employees and played important role in managing and implementing change.
The results of the study revealed that change in the employees’ performance was viewed by employees as positive and significant and supplement this point with extensive training and development programs, new performance management system, organizational restructuring, amplified remuneration package, enhanced communication, and betterment of the working environment.
Keeping in view the perspective of the management and the employees on the change after privatization, the research study concludes that though K.E.S.C’s management carried out the change program in a proper and organized manner, by considering several critical factors for its successful implementation, there were still a few gaps observed with respect to job security and communication that in the end lead to employees’ dissatisfaction and reservations with the change process. These gaps are highlighted in the recommendations and this study believes that if K.E.S.C’s management includes them in their future plans, then it can bring more productivity and efficiency in the performance of the employees.
From Raw to Finished Cotton—Characterization by Interface Phenomena
Authors: Grancarić Ana Marija , Tarbuk Anita , Hadžić Samira , Simončič Barbara 
Published: February 2022

Abstract
Interface phenomena that occur at the solid–liquid interface, such as wettability, adsorption, and particle aggregation, depend on the kind and magnitude of the solid surface free energy and electrokinetic properties found in water solutions. These phenomena are crucial for textile dyeing, finishing, and care. They characterize the material surface and change with different material pretreatment and finishing. In this paper, electrokinetic potential, isoelectric point, point of zero charge, a specific amount of surface charge and surface free energy of raw, enzymatically scoured, bleached, and finished cotton fabrics were investigated. Electrokinetic potential was measured by a streaming potential method and a specific quantity of surface charge by the back-titration method. For determination of the solid surface free energy components, the thin-layer wicking and contact-angle methods were used. On the basis of these results, components of solid surface free energy were calculated and discussed.
COVID-19 Infection or Buttock Injections? The Dangers of Aesthetics and Socializing During a Pandemic
Authors: Anthony Cleland Derrick , Tsai Clarence H. H. , Vo Joslyn , Moretta Dafne 
Published: February 2022

Abstract

Introduction
Silicone (polydimethylsiloxane) injections are used for cosmetic augmentation. Their use is associated with life-threatening complications such as acute pneumonitis, alveolar hemorrhage, and acute respiratory distress among others [1,2]. We report a case of a Hispanic woman who developed severe respiratory distress syndrome after gluteal silicone injections.

Case Presentation
A 44-year-old Hispanic female presented to the Emergency Department complaining of progressive dyspnea on exertion for two weeks. Chest imaging revealed patchy bibasilar airspace opacities of peripheral distribution. Labs were significant for leukocytosis, elevated PT, D-dimer, lactate dehydrogenase, and fibrinogen, concerning for COVID-19, however SARS-CoV-2 testing was negative multiple times. The patient later became encephalopathic, hypoxemic, and eventually required intubation. Further history uncovered that the patient had received illicit gluteal silicone injections a few days prior to her onset of symptoms. The patient was diagnosed with silicone embolism syndrome (SES) and initiated on high dose intravenous methylprednisolone [1].

Case Discussion
Patients from lower socioeconomic backgrounds utilize illicit services to receive silicone injections at minimal costs. This leads to dangerous outcomes. The serology and imaging findings observed in our case have similarities to the typical presentation of COVID-19 pneumonia making the initial diagnosis difficult. This case serves as a cautionary tale of the importance of thorough history taking in patients with concern for COVID-19.
Migration and community in an age of digital connectivity: A survey of media use and integration amongst migrants in Iceland
Authors: Hoffmann Lara , Jónsson Þorlákur Axel , Meckl Markus 
Published: February 2022

Abstract
Information and communication technologies enable migrants to maintain bonds with multiple communities. Little is known about the association between migrants’ connections to their country of origin and different integration practices in online and offline communities in the receiving society. We draw on a survey conducted amongst migrants in Iceland (N = 2,139) and conduct three regression analyses to identify determinants of migrants’ use of media and social media from their country of origin. Contrary to other studies, we do not find evidence of reactive transnationalism (i.e., migrants seeking out connections to their places of origin due to dissatisfaction with life in the receiving society) as a response to negative attitudes towards the receiving society. We identify distinct patterns of online and offline integration: Migrants with frequent contact with their countries of origin are less integrated locally in terms of offline activities. However, they are more integrated in digital communities of the receiving society, and use receiving-country media more frequently, thus following a strategy of digital biculturalism.
