The impact of the COVID-19 pandemic on the delivery of primary health care services
Authors: Ahmad Al-Abdulla Samya , O’Dwyer Robin
Published: October 2021

Background: In response to the COVID-19 global pandemic the Primary Health Care Corporation (PHCC) in Qatar recognized the need to limit face-to-face consultations within health centers in order to prevent unnecessary spread of the virus by offering an alternative solution for patients to access primary health care. PHCC responded by establishing teleconsultation services (telephone and video) within health centers and establishing a community call center offering teleconsultations for family medicine, ophthalmology, and dentistry services, with a nursing tele-triage service operating 24 hours a day, 7 days a week. Methods: All previously booked appointments within health centers were converted to outbound telephone consultations. The community call center was widely advertised and received incoming patient inquiries. This led to an analysis of the teleconsultation service utilization on a daily, weekly, and monthly basis. Results: The 27 health centers successfully provided 703,845 teleconsultations (via video and telephone calls) between 1st April and 31st October 2020 compared to 964,285 in-person consultations (). A significant percentage of patients continue to opt for a telephone consultation rather than a face-to-face visit. Between 29th March and 28th November 2020, the community call center received a total of 159,137 calls with 61% of calls managed and resolved by a nurse, without the need for a consultation by a physician. Conclusion: The rapid response by PHCC to find alternative means to offer primary health care services during a pandemic was activated early and the public responded positively. Teleconsultation services within Qatar have been widely accepted by patients who have more choices to access primary care services. Since April 2020, when teleconsultations were fully implemented in PHCC, to October 2020, 42% of all consultations have been via teleconsultation (). Teleconsultation services both within health centers and the community call center, offer an alternative means of care delivery, empowering patients.

Authors: Abdulrazzaq Sama , Al-Ahbabi Turki Faris , Elsherif Mohammed Aly , Ghazy Ahmed , Hammoudeh Samer
Published: October 2021

Background: A rising number of bariatric surgeries (BS) are associated with a rise in medical complications including protein malnutrition and neuromuscular complications (NM). Although BS were minimized during the COVID-19 pandemic, the number of admissions due to complications continued to increase. Proper outpatient follow-up was negatively affected during the pandemic. We aim to address the rising rate of post-BS admissions during COVID-19 pandemic compared to the previous six years' admissions with a similar diagnosis. Methods: This is a retrospective observational study of 33 patients admitted with malnutrition and/or NM complications post-BS at Hamad General Hospital, Qatar, from 1st Jan 2014–30th Aug 2020. Patients’ data were retrieved from the electronic medical records and bariatric patients’ database. Malnutrition was evaluated using serum albumin, total protein, minerals, and vitamins. Nerve conduction study/electromyography confirmed NM complications. Risk factors addressed were interval between BS and admission, gastrointestinal symptoms, total weight loss (TWL %), excess weight loss (EWL %), and irregular multivitamins intake. Results: The study included 21 patients, admitted from 1st Jan 2014-31th Dec 2019, compared to 12 patients during the period 1st Jan-30th August 2020. The patients’ mean age was 26.90 ± 9.81 years, and females were 18 (59%). The mean pre-operative weight, Body Mass Index (BMI), post-operative weight, BMI were: 123.48 kg, 44.37 kg/m2 and 84.61 kg – 30.67 kg/m2, respectively. The mean weight loss, EWL% and TWL% was 38.04 kg, 73.26%, and 30.57%, respectively. The time interval between BS and admission was 7.18 ± 8.99 months. Seventeen patients (51.5%) had malnutrition, while 16 (58.5%) had NM complications, 87.9% were off multivitamins, and 66% had gastrointestinal symptoms. All patients showed minerals and vitamins deficiencies, especially for vitamin D (81.8%) and potassium (30.3%). Conclusion: Despite a reduction in the number of BS during the COVID-19 pandemic, an increase in the rate of hospital admissions with medical complications after BS was observed.
What COVID-19 has taught the world
Authors: Barman Rati , Ambra Naseem , Barman Manish
Published: October 2021

Background: A novel coronavirus (SARS-CoV-2) has captured global recognition in a short period of time by dramatically impacting people's everyday lives and emerged as a public health emergency. Undoubtedly, it shows that lessons learned from past coronavirus epidemics such as the Middle East Respiratory Syndrome (MERS) and the Serious Acute Respiratory Syndrome (SARS) were not adequate and thus left us ill-prepared to deal with the challenges presently raised by the COVID-19 pandemic. Methods: COVID-19 adds to the list of previous outbreaks of infectious disease epidemics that try to remind us that we live in an ecosystem where the relationship between human and animal life, and the environment must be respected in order to survive and prosper. Rapid urbanization and our forestland invasion have created a new interface between humans and wildlife, and have exposed humans to unfamiliar species, frequently involving unfamiliar organisms and exotic wildlife. Findings: Every pandemic is nature’s way of reminding us that the interrelationship between all forms of existence needs to be recognized. To limit new infectious outbreaks, the transdisciplinary ‘One Health’ solution incorporating ‘Health in All Policy’ involving all stakeholders especially environmental health and social sciences is being advocated (). Conclusion: Savings and investments should be made by everyone to meet the unexpected. Stigmatization and prejudice among individuals in the world should be discouraged. Special attention should be paid to the elderly, as their immune system is weak. Health and safety precautions such as physical distancing and health hygiene etiquettes should be considered as part of life. Global experience teaches that containment steps and active tracing of contacts are effective to minimize the economic burden of disease and enhance knowledge of disease processes, health issues, disease emergence, and re-emergence. These lessons will help us to battle future pandemics.
AIDS-defining opportunistic illnesses in Qatar, 2000–2016: a cohort study
Authors: Ali Maisa , Qasim Mahmoud , AlSoub Hussam
Published: October 2021

Background: Human immunodeficiency virus (HIV) infection remains a major health problem since discovery of the virus in 1981. Globally, since the introduction of antiretroviral therapy in 1996, acquired immunodeficiency syndrome (AIDS) related deaths fell by more than 25% between 2005 and 2011. HIV related opportunistic illnesses (OIs) are less common, especially with the use of prophylaxis. This study aims to assess the incidence of HIV infection and related OIs in Qatar over a 17-year period. Methods: This is a retrospective cohort study of all HIV infected patients registered in Qatar from 2000-2016. Incidence of HIV infection and related OIs were calculated per 100,000 population. Demographic and clinical characteristics were compared between two groups of patients with and without OIs. Results: In 167 cases with HIV infection, 54 (32.3%) had OIs. The average incidence rate of HIV infection over 16 years is 0.69 per 100,000 population, and the incidence rate for OIs is 0.27 per 100,000 population (Figure 1). The most common OIs is pneumocystis jirovecii pneumonia (PCP), seen in 25% of cases, followed by cytomegalovirus (CMV) retinitis with 7.2%, tuberculosis 5.4%, toxoplasmosis 4.2%, and less than 2% for Kaposi sarcoma and cryptococcal infection. The treatment outcome of cases with OIs was: cure in 59.3%, failure in 3.7%. Mortality within 3 months of OIs was 3.7%, whereas 33.4% accounted for loss to follow up after starting the treatment due to patients leaving the country. Most patients in both groups were young males. The CD4 lymphocyte count and percentage (CD4%), CD4/CD8 ratio and viral load were statistically significant risk factors in cases with OIs (p < 0.05). Presence of comorbidities was lower in patients with OIs (p = 0.032) (). Conclusion: Qatar has a low prevalence rate for HIV infection and related opportunistic illness. Early diagnosis and use of antiretroviral therapy are important measures to decrease the rate of opportunistic illness.

Published: October 2021

Background:
Candida auris, within the last decade, has emerged as a multidrug resistant public health threat that can lead to hospital outbreaks. It is an invasive fungal yeast resistant to multiple antifungal agents. The mode of transmission is through contaminated hospital items (including clothes and furniture) and interventions by staff. Two Candida auris outbreaks occurred in Qatar. The first outbreak was in Al Wakra Hospital (AWH), which is a facility of Hamad Medical Corporation (HMC), the principal public healthcare provider in the State of Qatar. As concluded by Eyre DW, et al. (2018), a series of interventions and environmental screening program may reduce the Candida auris outbreak. A screening toolkit that includes a checklist based on an existing protocol and operationally defined criteria is a key preventive measure for Candida auris identification. We aim to attain 100% compliance with screening suspected patients and preventing further outbreaks. Methods: A screening protocol toolkit was created for eligible patients that allowed early identification and prompt intervention therefore enhancing the provision of high-quality, efficient, cost effective, and safe patient care. Furthermore, implementation of an Outbreak Prevention Bundle had been proven effective in preventing the spread and comprised: (1) prophylactic contact precautions, (2) blanket screening of at risk/exposed patients, (3) environmental sampling, and (4) hydrogen peroxide disinfection. Results/Findings/Recommendations: In 2020, continuous screening was maintained for patients fitting the HMC criteria. The protocol for the management of outbreaks was implemented. The number of COVID-19 positive cases peaked during July - August 2020 when COVID-19 patients were transferred to AWH (). Overall, AWH reached 407 cumulative days without Candida auris outbreak (). Conclusion:
Candida auris outbreak is preventable through early identification via screening and implementation of an Outbreak Prevention Bundle. This method has led to no active outbreak in AWH since August 2019 until October 2020.

Published: October 2021

Background: Virtual reality (VR) is still an evolving domain that presents a versatile medium to simulate various environments and scenarios that can be easily reset between users, which can be particularly useful for training purposes. In this pilot study, we recreated the interior of a modular ambulance patient compartment with elements that can be moved and also had access to the real physical ambulance with the same interior design and equipment. The primary objective of this study was to determine the usability of the VR patient compartment in terms of functionality and sense of presence. Methods: Paramedics were invited to take part in this pilot study which involved them attending a 15-minute presentation about ambulance safety and ergonomics, familiarise themselves with the VR equipment (), position the modular elements of the ambulance patient compartment in the VR or real setting (and vice versa), and complete a questionnaire corresponding to the task completed and adapted from an existing tool. They were unknowingly timed during the activities inside the real and VR ambulance for comparative purposes. Results: Twenty-seven participants were recruited, 77.8% of whom had no prior VR experience.

On the 7-point Likert scale questionnaire, the participants scored the various aspects of usability (ease of grabbing elements, ease of recognising fixed/movable elements, distinguishing close from far objects, ease of “playing” the game…) between 5.59 to 6.26 and their sense of presence as 6.11 (SD = 1.121). Participants were faster arranging the modular elements in the VR setting than in the real one (8.78 min, SD = 4.47 versus 13.05 min, SD = 5.04). Conclusion: VR technology and potential applications are still rapidly developing. This pilot study shows promising results in terms of ease of use and sense of presence for the paramedics. This demonstrates that VR can be used for interactive familiarisation with an environment such as an ambulance patient compartment and can be used to assist in their design.

The Australian Government is financially incentivising work integrated learning (WIL) to enhance graduate employability. As such, universities are currently expanding WIL pedagogies and practices from their traditional domain of professional degrees, to be incorporate into almost all university degrees. Using Kemmis’ Theory of Practice Architecture, this study investigated the practices of established WIL practitioners in universities and uncovers what can be referred to as a WIL ecology of practice. This ecology comprises of key WIL practices, including: networking and selling, negotiating, collaborating and innovating and legitimising. The findings from this study offer important insights into how higher education institutions may develop a WIL ecology of practice, and critically, achieve WIL funding objectives, which has arguably become ever more important given the challenges COVID-19 has presented to university operational budgets.
Facilitating a supportive learning experience: The lecturer's role in addressing mental health issues of university students during COVID-19
Authors:   Queensland University of Technology, Australia, Heim Caroline , Heim Christian ,   University of Queensland, Australia
Published: October 2021

During COVID-19, rates of mental health issues, particularly anxiety, rose significantly in university students. In the scramble to adapt to online learning, university professors were overwhelmed with material aimed at facilitating a supportive learning experience and preserving student academic performance in online contexts yet were ill-equipped to cope with the increased volume of mental health issues encountered. Many studies attest to the association between poor mental health and academic performance. It has been shown that students often report their mental health issues to university professors who are called upon to cope with these issues as best they can. This paper outlines strategies undertaken, in the context of a novel undergraduate mental health program, to address emergent mental health issues during Covid-19 student isolation. These practical, cost effective interventions can be used to successfully give voice to ongoing student mental health issues in a post-Covid world and to help professors feel equipped and empowered enough to contribute to stemming the tide of rising rates of mental illness meaningfully, appropriately and professionally.

This paper discusses how pedagogical theory can be used in conceptualizing a collaborative teaching development program in higher education. A theoretically driven teaching development program can be of benefit to both the reviewer and the reviewee by providing (a) a foundation for the reviewee to examine their educational content being reviewed; and (b) a systematic framework for the reviewee for evaluating the content under review. Appropriately used pedagogical theory enables the constructive alignment of teaching, learning, and assessment. This collaborative, self-reflective, and bi-directional teaching development process facilitates a sense of self-determination, which facilitates motivation and achievement of goals.

Analysis of the ecological condition of water and bottom substrates of the lower Dniester by the method of biotesting on microalgae
Authors:   Ukrainian Scientific Center of Ecology of the Sea, Ukraine, Semenova Olga
Published: October 2021

In the autumn-spring periods 2018 - 2020. biotesting of water and bottom sediments of the lower Dniester and Ukrainian coastal waters of the Dniester region of the Black Sea was carried out by biotesting on a laboratory culture of planktonic algae Desmodesmus communis. The assessment of the ecological and toxicological situation and a comparative analysis of indicators of the level of pollution of the ecosystem of the “lower reaches of the Dniester” testify to the chronic pollution of this ecosystem by dangerous toxicants, acute toxicity occurs only during peak periods, while chronic toxicity is constantly manifested. It was found that in the overwhelming majority of water areas with different nature of anthropogenic factors and anthropogenic load, there were no toxic substances. Hazardous pollutants were more often found in the surface water layer of the zones affected by urban wastewaters on the Ukrainian coast of the Dniester region of the Black Sea.

Published: October 2021

The researches were carried out in 2020 on the main course of Bistrița River, upstream the confluence with Siret River. The biological material was sampled in 10 sampling sites placed on the main course of Bistrița River. Seventeen fish species were identified, one of them being a non-native one: Pseudorasbora parva. We found that the chub and the Prussian carp are characteristic species. Species diversity is quite high, being identified even 12 fish species in some of the sampling sites. There is an unequal distribution of individuals by species. The main threats in the research area are the organic inputs and the increase of turbidity. However, there are no great imbalances, and there is a good capacity for self-support of aquatic communities.

Published: October 2021

This work is based on helminthological data of amphibians, collected since 2013 until 2020, in the Republic of Moldova. The investigations on anura amphibians were conducted in the laboratory of Parazitology and Helminthology of the Institute of Zoology. One of the most common parasitic diseases in ruminants is fasciolosis, caused by the trematode Fasciola hepatica species. The results of parasitological research showed that adult cattle were infected with fascioles in 66.4% of cases, and young cattle - in 46.1% of cases. This is largely due to the grazing of animals of different species and ages in limited areas.The presence of the trematode species Haplometra cylindracea was established in 78% of cases in the amphibians in the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis). The results of laboratory helminthological investigations have shown that the relationships between the Fasciola hepatica miracidium and the Haplometra cylindracea miracidium are antagonistic. Amphibians of the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis) infested with Haplometra cylindracea tremateda may play an important role in the prophylaxis of fasciolosis.

The Republic of Moldova is a small European country where long-term studies have been more of an exception than a rule. Being an agrarian country, the mosaic of natural and artificial habitats is found on a smaller scale, namely in the Sărata river meadow, and in Sărata Nouă lake and surrounding. The Sărata River is a right tributary of the Prut River in the Republic of Moldova, having a quiet plain character, with a mosaic of natural and artificial habitats which are traditionally managed. The area overlaps with the East-Elbic migration route, the short distance to the Prut River and being located in the northern part of the Bugeac steppe, ensures a great diversity both in winter and nesting, and especially in the migration period. During 2016-2021, we registered the presence of 126 bird species, which represent 46% of the total species encountered in the Republic of Moldova.

The major desideratum of the screening action of the hip dysplasia is the early discovery of the disease and its highlighting at an early stage. Hip dysplasia is interpreted as an abnormal and / or defective development of the hip (hip joint), which can cause excessive wear of the articular cartilage due to the support of body weight leading to the development of arthritis, often called degenerative joint disease or simply osteoarthritis, these terms being used randomly. All these morphofunctional changes can be detected early, by different methods of observation, which necessarily involve X-ray radiological examination, performing a complex analysis of the images studied, according to the recommendations of various international organizations such as FCI Fédération Cynologique Internationale (FCI) - score which includes measuring the Norberg angle, the Orthopedic Foundation for Animals (OFA), the PennHIP Program - which involves measuring hip laxity, etc.

The excessive use of Mud Shells (Anodentia edentula) as a staple food by the people of Kalangan Village, Central Tapanuli Regency caused the decline of the shellfish population. This is marked by the scattering of mud shells at research sites and often people conduct shell-searching activities at low tide. Therefore, a scientific study is needed to know the density and distribution patterns as the basis for the possibility of cultivation activities, management of mud shell germplasm (Anodentia edentula), and mangrove ecosystems in kalangan area in the future optimally, sustainably, and sustainably. The study was conducted in September 2020, using the 1x1m2 transect method purposive sampling at low tide. The results showed that the density of Mud Shells (Anodentia edentula) amounted to 150 ind/m2 in Station I, 0 ind/m2 in Station II with distribution pattern clustering, and 43 ind/m2 in Station III with distribution pattern random. With the evidence that there is a research station that contain zero mud clam and with unsimilarity in distribution pattern that should be clustering in every research station, therefore it can be concluded that the abudance of mud clam in the ecosystem already decline both quantifically and qualitativelyand requires conservation and cultivation action to ensure its existence in the future.

importância do planejamento nas contratações públicas
Authors: Medeiros Claudia Lucio de
Published: October 2021

O processo de contratação pública compreende três fases importantes: planejamento, seleção da melhor proposta, e execução contratual. A nova visão de processo centraliza a ideia de que o planejamento consiste na etapa mais importante, porquanto todas as demais estarão condicionadas à descrição correta e adequada do que se pretende contratar. Do contrário, um planejamento inadequado acarreta incidentes indesejáveis, como aditamentos contratuais desnecessários, contratações emergenciais decorrentes de desídia ou má gestão, dentre outras práticas arbitrárias e lesivas ao dinheiro público. Este artigo presenta uma abordagem sobre os principais aspectos inerentes ao processo de contratação pública. A metodologia utilizada deu-se por meio de levantamento da legislação vigente, assim como das melhores práticas recomendadas pela doutrina e jurisprudência. Por meio do presente estudo, infere-se que é necessário reconhecer a importância do planejamento no processo de contratação pública, porque viabiliza a boa gestão dos recursos públicos, mediante a prevenção de falhas e supressão de incertezas.
Objectification and Instrumentalization: The Activation of Thanatos in Connection with “Body-Power”; or the Human Body as a Critical Object of Power in the Resent Social Reality
Authors: Nikolova Yana D.
Published: October 2021

This paper is about the ways in which the human body has been objectified under and through the use of power. The article explains the different aspects and ways of objectification of the body and the hidden nature of human behaviour that results from activation of the inner human instincts - the death drive, called Thanatos (Note 1) and the life drive called Eros as a response to Thanatos. By using the theories of Freud, Nussbaum, Erikson, Fanon and Foucault, the relationship between the human body and external power is examined. Using some recent events (such as the Covid-19 pandemic, the world lockdown and the Black Lives Matter movement) human behaviour is seen to result from activation of the inner drives (Eros (Note 2) and Thanatos), but also to be linked to the psychosexual and psychosocial aspects of human development.

Coronavirus 2019 is a global health concern that has left most countries in a state of severe economic meltdown. Scientific research has been down on the virus and its impact on various sectors but that of the Nigerian aquaculture industry has been missing. This paves the way for this research to aim at bridging this gap by looking at the perception of fish farmers on the influence of coronavirus on their activities, the challenges they face during the period of the virus, and the coping strategies adopted to mitigate the impact of the virus. The research used cross sectional survey design with the sample size being 11 fish farmers living in Oyo state, Nigeria. Homogeneous purposive sampling was used and primary data collected through the use of google form. The data collected was analysis using SPSS version 25.0. The result of the analysed data showed that: on socioeconomic characteristics; the majority of the respondent reported that Coronavirus has had an effect on their fishing activity and they were mostly small scale farmers with catfish being the predominate fish farmed. The majority of fish farmers perceived demand decline, high cost of production, fish being more expensive, and reduction of manpower on the farm due to lockdown measures. Reduction in walk-in customers to the farm was revealed as the major challenge posed by the pandemic, while the inability to get technical support as least. On coping strategies adopted, it was revealed that farmers have resorted to the development of their own feed.

Cultural Institutions during COVID-19. Museum Strategies
for Reaching the Public are presented. It was conducted
by the Forum of Museum Educators as commissioned by
the National Institute for Museums and Public Collections
(NIMOZ). The main purpose was to show the impact
of the pandemic on the operations of museums after
12 March 2020 when the decision was made in Poland
to close the culture sector to the public; the aim was
also to diagnose and analyse problems that the pandemic
caused, and to point to the directions of impact on
cultural institutions possible in the future, namely after
restoring ‘normality’. The perspective adopted in the
research, i.e., institutional and individual one, enables
a multifaceted analysis of the processes initiated by
museums in response to unclear and often complicated
mechanisms of the new pandemic reality, which still

Published: October 2021

Context: Chronic diseases (CD) are defined as symptoms or disabilities, caused by diseases, genetic factors, and injury requiring long-term treatment. Intelligent alarm systems, which collect patient health data and transfer it to a medical server, help track and avoid future incidents. Method: The search terms were “computer network” OR “information systems” OR “wireless technology” OR “decision support systems” AND “chronic disease” OR “chronic disease” in major electronic databases, including Pubmed/Medline, Scopus, Embase, ISI Web of Science, and Cochrane Central. Results: The search resulted in 1275 articles with 11 specific to intelligence-based systems in chronic medical conditions until 08 June 2021. The creation of different access levels for care providers in the system and application customization according to CD conditions were the goals that can be achieved in future research. The human-computer interface (HCI) systems, smart home, and software, such as Fitbit using IoMT to monitor health metrics in people with different CDs, are introduced so far. Conclusions: These systems, if provided on the web and mobile platform, can be accessed at any time and place and are more efficient. Finally, the combination of clinical decision support systems with artificial intelligence has beneficial effects on physician's systems, increases the accuracy in CD diagnosis, and improves the pain management. This intelligent system demonstrates factors influencing back to work and allows identifying high-risk patients and their potential to handle activities of daily living.
Does geographical concentration affect the profitability of Russian enterprises?
Authors: Rostislav K.V.
Published: October 2021

The article shows that profitability is, first, the best measurable approximation to productivity at the level of individual enterprises, and, second, an indicator that captures the possible benefits (or costs) of geographical concentration (agglomeration externalities) in their entirety. The analysis of open microdata of Rosstat and the Federal Tax Service on organizations with an average number of employees of no more than 250 reveals that in Russia the differences in profitability between cities and between industries with different levels of spatial concentration are small and poorly related to geographical conditions (the so-called benefits of localization and urbanization). Worse terms of trade, in particular higher labour costs, outweigh the productivity gains from concentration. At the same time, there are weak signs of a smaller spread of profitability among enterprises in more central territories due to better opportunities for imitation and exchange of experience. The profitability of enterprises is significantly influenced by their industry, but this relationship does not arise due to differences between industries in the degree of their geographical concentration. To assess the agglomeration effects, new measures of centrality that appreciate the network nature of territorial relations between residents of localities were used.
On social permeability of municipal borders
Authors: Yashunsky A.D.
Published: October 2021

The article investigates the intensity of social interaction between the population of different municipalities in Russian Federation. This interaction is estimated using user profile data from online social networks: a data source that grows more and more popular in population geography studies. We build a qualitative indicator of social interaction using data on the number of interregional friendship links for «VKontakte» social network users that live in different municipalities and have an open social network profile. We show that the intensity of social interaction is higher on the average for municipalities that share a common border. Social interaction intensity data is then used to characterize the permeability of municipality borders. We choose the least permeable borders among all border segments of municipalities in Russian Federation: those with the smallest transborder interaction intensity values and describe the social barriers that are revealed this way. We describe various configurations of these barriers and suggest hypotheses for the reasons why such barriers appear or do not appear. We also analyze several groups of socially insular groups of municipalities in the Khanty- Mansi Autonomous Okrug and the Yamalo-Nenets Autonomous Okrug and suggest possible reasons for their insularity.
