Feasibility of Transcutaneous Method for Carbon Dioxide Monitoring in
an Intensive Care Unit
Authors: Boyacı Nazlıhan , Mammadova Sariyya , Naurizbay Nurgül , Güleryüz Merve , İnci Kamil , Gürsel Gül
Published: January 2022

Background:

Transcutaneous partial pressure of carbon dioxide (PtCO2) monitorization
provides a continuous and non-invasive measurement of partial pressure of carbon dioxide (pCO2).
In addition, peripheral oxygen saturation (SpO2) can also be measured and followed by this
method. However, data regarding the correlation between PtCO2 and arterial pCO2 (PaCO2) measurements
acquired from peripheric arterial blood gas is controversial.

Objective:

We aimed to determine the reliability of PtCO2 with PaCO2 based on its advantages, like
non-invasiveness and continuous applicability.

Methods:

Thirty-five adult patients with hypercapnic respiratory failure admitted to our tertiary
medical intensive care unit (ICU) were included. Then we compared PtCO2 and PaCO2 and both
SpO2 measurements simultaneously. Thirty measurements from the deltoid zone and 26 measurements
from the cheek zone were applied.

Results:

PtCO2 could not be measured from the deltoid region in 5 (14%) patients. SpO2 and pulse
rate could not be detected at 8 (26.7%) of the deltoid zone measurements. Correlation coefficients
between PtCO2 and PaCO2 from deltoid and the cheek region were r: 0,915 and r: 0,946 (p =
0,0001). In comparison with the Bland-Altman test, difference in deltoid measurements was -1,38
± 1,18 mmHg (p = 0.252) and in cheek measurements it was -5,12 ± 0,92 mmHg (p = 0,0001).
There was no statistically significant difference between SpO2 measurements in each region.

Conclusion:

Our results suggest that PtCO2 and SpO2 measurements from the deltoid region are reliable
compared to the arterial blood gas analysis in hypercapnic ICU patients. More randomized
controlled studies investigating the effects of different measurement areas, hemodynamic parameters,
and hemoglobin levels are needed.
Susceptibility to Rhinovirus-induced Early Wheezing as a Risk Factor for
Subsequent Asthma Development
Authors: Mikkola Hannele , Honkila Minna , Tapiainen Terhi , Jartti Tuomas
Published: January 2022

Rhinovirus is one of the two most common viral agents that cause bronchiolitis in young
children. During the first 12 months, it is second to the respiratory syncytial virus, but after 12
months, it begins dominating the statistics. Wheezing and dry cough are typical clinical symptoms
indicative of rhinovirus-induced bronchiolitis, although overlap of symptoms with other virus infections
is common. Several studies have shown that atopic predisposition and reduced interferon responses
increase susceptibility to rhinovirus-induced wheezing. More recent studies have found
that certain genetic variations at strong asthma loci also increase susceptibility. Rhinovirus-induced
wheezing in the early years of life is known to increase the risk of subsequent asthma development
and may be associated with airway remodeling. This risk is increased by aeroallergen sensitization.
Currently, there are no clinically approved preventive treatments for asthma. However, studies
show promising results indicating that children with rhinovirus-affected first-time wheezing respond
to bronchodilators in terms of less short-term symptoms and that controlling airway inflammatory
responses with anti-inflammatory medication may markedly decrease asthma development.
Also, enhancing resistance to respiratory viruses has been a topic of discussion. Primary and secondary
prevention strategies are being developed with the aim of decreasing the incidence of asthma.
Here, we review the current knowledge on rhinovirus-induced early wheezing as a risk factor
for subsequent asthma development and related asthma-prevention strategies.
Vitamin D and Omega-3 Polyunsaturated Fatty Acids in Type 1 Diabetes Modulation
Authors: Bastos Thais Sibioni Berti , Braga Tárcio Teodoro , Davanso Mariana Rodrigues
Published: January 2022

Background:

Type 1 diabetes (T1D) is a chronic autoimmune disease affecting people globally. Usually developed during childhood, T1D is characterized by the destruction of pancreatic β-cells due to immune cell attack and the establishment of an inflammatory process.

Objective:

The study aimed to investigate the effects of vitamin D through its nuclear receptor and the ω-3 polyunsaturated fatty acids (PUFAs) through their lipid derivatives in T1D modulation. Both components exert anti-inflammatory activity and act directly on cells of the immune system, attenuating the destruction of insulin-producing cells. Furthermore, they lead to a better glycemic level, reducing the need for insulin and a normal immune state, such as C-peptide maintenance.

Method:

Presently, our review highlights the significant studies that evaluated the supplementation of vitamin D and ω-3 PUFAs in humans and animal models in the modulation of T1D.

Conclusion:

The data collected suggests that supplementation can provide potential benefits, mainly when done early in the diagnosis, since it reduces the need for insulin and the risk of complications generated by the disease.
Equine astma: huidige kennis van zaken
Authors: Verhaeghe L.M. , Lefère L. , Dufourni A. , Paulussen E. , Van Loon G.
Published: January 2022

Equine astma is de overkoepelende term voor een inflammatoir proces ter hoogte van de diepere luchtwegen. Deze aandoening wordt verder onderverdeeld in lichte tot matige astma, beter bekend als “inflammatory airway disease” (IAD), en ernstige astma, beter bekend als “recurrent airway obstruction” (RAO). RAO veroorzaakt inflammatie en obstructie van de diepe luchtwegen, wat leidt tot chronische hoest, verhoogde ademhalingsinspanning in rust en inspanningsintolerantie, meestal bij paarden ouder dan zeven jaar. IAD daarentegen kan op elke leeftijd voorkomen en de klinische tekenen zijn vaak veel subtieler, namelijk verminderd presteren en occasioneel hoesten. Equine astma wordt voornamelijk getriggerd door een hoge concentratie aan stof en schimmelsporen in de stalomgeving of pollen tijdens de zomermaanden in het geval van “summer pasture associated” RAO (SPARAO). De gouden standaard om equine astma te diagnosticeren is het uitvoeren van een endoscopie, gevolgd door een broncho-alveolaire lavage (BAL). Het aanpassen van de omgeving is en blijft de belangrijkste behandelingsmethode, vaak in combinatie met het tijdelijk toedienen van corticosteroïden en bronchodilatatoren.
The benefits of computed tomography imaging in the diagnosis, prognosis and treatment planning of equine orthopedic patients illustrated by six cases

Published: January 2022

Radiography and/or ultrasonography are the first imaging modalities for diagnosing orthopedic pathology in equine patients. However, in some cases, cross-sectional imaging is necessary to reach a more accurate diagnosis. Six cases were retrospectively selected from the imaging database of the Faculty of Veterinary Medicine (Ghent University) to illustrate the benefits of computed tomography (CT) in orthopedic patients. In two cases, CT demonstrated osteomyelitis lesions in two young foals, which could not be detected with radiography and ultrasonography. In three cases, CT was performed for surgical planning of fracture repair, and in one case CT demonstrated multiple lesions at the soft tissues and ligamentous insertions in the stifle. In all cases, CT revealed additional findings, which were important for the treatment and prognosis of the patient.

Published: January 2022

The microwave diagnostics of discharges occurring in an artificial cloud of charged water droplets created in an open air simulating the environment of thunderclouds is implemented. An artificial cloud with a droplet size of about 1 microns is opaque in the visible range, so intra-cloud discharges are not available for investigation by traditional methods in the spark discharge physics based on the registration of visible discharge radiation. Microwaves pass through such a cloud without noticeable attenuation, they interact only with the plasma of discharges occurring in the cloud. The probing microwave radiation had a wavelength of 8 mm. The attenuation of microwaves passed through the cloud was measured with temporary resolution of about 10 ns. The temporal characteristics of intra-cloud discharges were investigated.

Published: January 2022

Background

Early childhood education and care (ECEC) centers are ideal venues for food education. As smartphones and tablets are becoming increasingly popular in ECEC centers, technology can be used to deliver such pedagogical content. Evidence suggests that video games can affect fruit and vegetable (FV) consumption among 9- to 12-year-old children, but studies among preschoolers are scarce.

Objective

This paper describes the development of the Mole’s Veggie Adventures app and its effectiveness in increasing FV acceptance among Finnish and Polish preschoolers aged 3 to 6 years.

Methods

A multiprofessional team created an app to be used in ECEC centers in groups of 3 to 10 children. The app aimed to increase vegetable acceptance, and it was built using elements that support the development of self-regulation and social skills. Altogether, 7 Finnish and 4 Polish ECEC centers participated in the study. Before randomization, parents reported background factors and their children’s willingness to taste different FVs. The ECEC professionals in the intervention arm were instructed to use the app at least once a week during the 3- to 4-week intervention period. The main outcomes in this unblinded, cluster-randomized study were FV acceptance and relative FV acceptance. The first was calculated as a sum variable describing the children’s willingness to taste 25 different FVs, the second as FV acceptance divided by the number of FVs served. We used analysis of covariance to compare the FV acceptance and relative FV acceptance scores between the intervention and control groups at follow-up.

Results

A total of 221 children were included in the analysis. At follow-up, the intervention group (115/221, 52%) had higher FV acceptance scores (baseline adjusted difference of mean 7.22; 95% CI 1.41-13.03) than the control group (106/221, 48%). The intervention effect was parallel for relative FV acceptance scores (baseline adjusted difference of mean 0.28; 95% CI 0.05-0.52).

Conclusions

The Mole’s Veggie Adventures app has the potential to increase FV acceptance among preschoolers and can be a valuable tool in supporting food education in ECEC centers. Furthermore, the app can be feasibly incorporated into preschool routines in countries with different educational environments.

What are Digital Public Health Interventions? First Steps Toward a Definition and an Intervention Classification Framework
Authors: Wienert Julian , Jahnel Tina , Maaß Laura
Published: January 2022

Digital public health is an emerging field in population-based research and practice. The fast development of digital technologies provides a fundamentally new understanding of improving public health by using digitalization, especially in prevention and health promotion. The first step toward a better understanding of digital public health is to conceptualize the subject of the assessment by defining what digital public health interventions are. This is important, as one cannot evaluate tools if one does not know what precisely an intervention in this field can be. Therefore, this study aims to provide the first definition of digital public health interventions. We will merge leading models for public health functions by the World Health Organization, a framework for digital health technologies by the National Institute for Health and Care Excellence, and a user-centered approach to intervention development. Together, they provide an overview of the functions and areas of use for digital public health interventions. Nevertheless, one must keep in mind that public health functions can differ among different health care systems, limiting our new framework’s universal validity. We conclude that a digital public health intervention should address essential public health functions through digital means. Furthermore, it should include members of the target group in the development process to improve social acceptance and achieve a population health impact.
An Interactive Voice Response System to Increase Physical Activity and Prevent Cancer in the Rural Alabama Black Belt: Design and Usability Study (Preprint)
Authors: Thirumalai Mohanraj , Brown Nashira , Niranjan Soumya , Townsend Sh'Nese , Powell Mary Anne , Neal Whitney , Schleicher Erica , Raparla Venkatadri , Oster Robert , Demark-Wahnefried Wendy , Pekmezi Dori
Published: January 2022

BACKGROUND

Increased physical activity (PA) levels are associated with reduced risk and improved survival for several cancers; however, most Americans engage in less than the recommended levels of PA. Using interactive voice response (IVR) systems to provide personalized health education and counseling may represent a high-reach, low-cost strategy for addressing physical inactivity and cancer disparities in disproportionately burdened rural regions. However, there has been a paucity of research conducted in this area to date.

OBJECTIVE

The aim of this study is to design, develop, and test the usability of an IVR system aimed at increasing PA levels in the rural Alabama Black Belt.

METHODS

A pilot version of the IVR system was used to assess initial feasibility and acceptability. Detailed exit interviews were conducted to elicit participant feedback, which helped inform the development of a substantially upgraded in-house IVR system. This refined IVR system was then subjected to a sequential explanatory mixed methods evaluation. Participating rural county coordinators and research staff (N=10) tested the usability of the IVR system features for 2 weeks and then completed the System Usability Scale and qualitative semistructured interviews.

RESULTS

The study sample comprised mostly African American people, women, rural county coordinators, and research staff (N=10). Participants rated the IVR system with a mean score of 81 (SD 5) on the System Usability Scale, implying excellent usability. In total, 5 overarching themes emerged from the qualitative interviews: likes or dislikes of the intervention, barriers to or facilitators of PA, technical difficulties, quality of calls, and suggestions for intervention improvement. Message framing on step feedback, call completion incentives, and incremental goal-setting challenges were areas identified for improvement. The positive areas highlighted in the interviews included the personalized call schedules, flexibility to call in or receive a call, ability to make up for missed calls, narration, and PA tips.

CONCLUSIONS

The usability testing and feedback received from the rural county coordinators and research staff helped inform a final round of refinement to the IVR system before use in a large randomized controlled trial. This study stresses the importance of usability testing of all digital health interventions and the benefits it can offer to the intervention.
An mHealth App-Based Self-management Intervention for Family Members of Pediatric Transplant Recipients (myFAMI): Framework Design and Development Study (Preprint)
Authors: Adib Riddhiman , Das Dipranjan , Ahamed Sheikh Iqbal , Lerret Stacee Marie
Published: January 2022

BACKGROUND

Solid-organ transplantation is the treatment of choice for children with end-stage organ failure. Ongoing recovery and medical management at home after transplant are important for recovery and transition to daily life. Smartphones are widely used and hold the potential for aiding in the establishment of mobile health (mHealth) protocols. Health care providers, nurses, and computer scientists collaboratively designed and developed mHealth family self-management intervention (myFAMI), a smartphone-based intervention app to promote a family self-management intervention for pediatric transplant patients’ families.

OBJECTIVE

This paper presents outcomes of the design stages and development actions of the myFAMI app framework, along with key challenges, limitations, and strengths.

METHODS

The myFAMI app framework is built upon a theory-based intervention for pediatric transplant patients, with aid from the action research (AR) methodology. Based on initially defined design motivation, the team of researchers collaboratively explored 4 research stages (research discussions, feedback and motivations, alpha testing, and deployment and release improvements) and developed features required for successful inauguration of the app in the real-world setting.

RESULTS

Deriving from app users and their functionalities, the myFAMI app framework is built with 2 primary components: the web app (for nurses’ and superadmin usage) and the smartphone app (for participant/family member usage). The web app stores survey responses and triggers alerts to nurses, when required, based on the family members’ response. The smartphone app presents the notifications sent from the server to the participants and captures survey responses. Both the web app and the smartphone app were built upon industry-standard software development frameworks and demonstrate great performance when deployed and used by study participants.

CONCLUSIONS

The paper summarizes a successful and efficient mHealth app-building process using a theory-based intervention in nursing and the AR methodology in computer science. Focusing on factors to improve efficiency enabled easy navigation of the app and collection of data. This work lays the foundation for researchers to carefully integrate necessary information (from the literature or experienced clinicians) to provide a robust and efficient solution and evaluate the acceptability, utility, and usability for similar studies in the future.

Digital Phenotype of Mood Disorders: a conceptual and critical review (Preprint)
Authors: Maatoug Redwan , Oudin Antoine , Adrien Vladimir , Saudreau Bertrand , Bonnot Olivier , Millet Bruno , Ferreri Florian , Mouchabac Stephane , Bourla Alexis
Published: January 2022

BACKGROUND

Mood disorder is commonly diagnosed and staged using clinical features that rely merely on subjective data. The concept of digital phenotyping is based on the idea that collecting real-time markers of human behavior allow one to determine the "digital signature of a pathology". This strategy assumes that behaviors are "quantifiable" from data extracted and analyzed through digital sensors, wearable devices or smartphones. That concept could bring a shift for the diagnosis of mood disorder, introducing for the first time paraclinical testing on psychiatric routine care.

OBJECTIVE

The main objective of this review was to propose a conceptual and critical review of the literature regarding the theoretical and technical principles of digital phenotypes applied to mood disorders.

METHODS

We conducted a selective review of the literature by updating a previous article and querying the PubMed database between February 2017 and November 2021 on titles with the relevant keywords regarding digital phenotyping, mood disorders and artificial intelligence.

RESULTS

858 articles were included for evaluation, 43 articles were taken into account and classified by data source (multimodal, actigraphy, ECG, smartphone use, voice analysis, body temperature). For depressive episodes, the main finding is the decrease in terms of functional and biological parameters (decrease in activities and walking, decrease in the number of calls and SMS, decrease in temperature and HRV) while the manic phase produces the reverse phenomenon (increase in activities, number of calls and HRV).

CONCLUSIONS

The various studies presented support the potential interest in digital phenotyping to computerize the clinical characteristics of mood disorders
Video-consultation in the Emergency Department: An Assessment of the Potential Benefit for a UK District General Hospital (Preprint)
Authors: Clarke Malcolm , Hands Linda , Turner Jane , George Grizelda , Jones Russell Wynn , Pullinger Rick , Kharbanda Rajesh , Kennedy James
Published: January 2022

BACKGROUND

District General Hospital Emergency department referrals to a tertiary centre depend on information available from a ‘generalist’ clinician in discussion with a specialist team. If there is uncertainty, the lowest risk strategy is often to transfer the patient. Video consultation allowing the specialist team to see and talk to the patient and local clinician whilst still in the Emergency department could improve decision making about patient transfer.

OBJECTIVE

This study assessed the potential benefit of real time video consultation between remote specialist and Emergency department patient and clinician across all specialities.

METHODS

Detailed patient data was collected prospectively for 6 months (between 16th January and 15th July 2012) on all patients presenting to a District General Hospital Emergency department who required input from a specialist team in the nearest tertiary centre. These patients were discussed retrospectively with the specialist teams to determine whether video conferencing could have benefited the management of the patient. The logistics for use of videoconferencing were explored.

RESULTS

18,799 patients were seen in the Emergency department during the study period. 413 referrals (2.2 %) were made to the tertiary centre specialist teams. Review of the patients transferred indicated 193 (46.7 % of transfer) might have benefited from video consultation (1.0 % of all patients). If the specialist team could be accessed via video conferencing only whilst a senior member was available in the hospital (08:00-22:00) then a maximum of only 5 patients per week across all specialities would use the equipment. If 24 hour specialist access was available this would increase to 7 patients per week.

CONCLUSIONS

In regions where there is direct transportation by ambulance of patients to specialist centres and there is regional Picture Archive and Communication System (PACS) then video consultation between emergency department patient and specialist has limited potential to improve patient management.

CLINICALTRIAL
Developing an Effective Strategy for the Enforcement of the Constitutional Mandate of the Senate Committee on Ethics, Code of Conduct and Public Petitions
Authors: Okon Emmanuel E. , Udombana Ngozi J.
Published: January 2022

The Senate Committee on Ethics, Code of Conduct and Public Petitions (ECCPP) is one of the committees of the Senate of Nigeria’s National Assembly. The Committee was one of the earliest Special committees established under Order XIII of the Senate Standing Orders 2015, as amended (SSO 2015). It is one of the committees through which the Senate conducts legislative investigations in fulfilment of its constitutional and statutory role under section 88 of the 1999 Constitution, as altered. The major challenge of the ECCPP Committee in the exercise of its investigation power is the refusal by some chief executives of government agencies and corporate organisations to honour its invitation. This study finds that among the reasons for this are the absence of ethical prescriptions in the SSO 2015 to guide the conduct of honourable members against unethical conduct that undermine their integrity, and absence of prescribed fine for failure to honour the Committee’s summons. To strengthen the enforcement capacity of the Committee, the study recommends, among others, that members of the Committee eschew unethical tendencies that undermine their integrity and conduct the business of the Committee in a manner that avoids conflicts of interest or its appearances.
Bipolaridad de las políticas de movilidad del Valle de Aburrá: análisis desde los instrumentos de gestión de la demanda implementados entre 1999 y 2019
Authors:   Universidad Externado de Colombia, Jaramillo Viviana Tobón
Published: January 2022

Medellín and the Aburrá Valley are internationally recognized for their capacity to design bold projects regarding transportation and sustainability. However, the city's mobility dynamics show a different reality: the number of vehicles has grown steadily over the last 20 years. The metropolitan inhabitants spend 44% more time mobilizing in the city than 12 years ago and air quality has become the main challenge on the city's environmental agenda. The purpose of this article is to understand, from the analysis of public policies, the reasons why no progress has been made in the implementation of policies that effectively discourage the use of private vehicles in the Aburrá Valley. Through the analysis of the demand management instruments enforced between 1999 and 2019, it is concluded that mobility policies produce contradictory effects with each other: they systematically avoid the restriction and disincentives to the use of automobiles and motorcycles and focusing predominantly on the expansion of road infrastructure. At the same time, they undertake actions, to a lesser extent, to stimulate the use of other means of transportation.

Diabetic Foot Ulcer Infections and Pseudomonas aeruginosa Biofilm Production During the COVID-19 Pandemic
Authors: Yakout Marwa A. , Abdelwahab Ibrahim A.
Published: January 2022

During the different waves of the coronavirus (COVID-19) pandemic, there has been an increased incidence of diabetes mellitus and diabetic foot infections. Among gram-negative bacteria, Pseudomonas aeruginosa is the predominant causative agent for diabetic foot ulcer infections in low-resource countries. P. aeruginosa possesses a variety of virulence factors, including biofilm formation. Biofilm formation is an important benchmark characteristic in the pathophysiology of diabetic foot ulceration. The main objective of the current study was to identify the most commonly isolated organisms and their antibiotic susceptibility patterns in diabetic foot patients during the COVID-19 pandemic. We also determined the genes associated with bacterial persistence and biofilm formation in the predominantly isolated organism. Accordingly, 100 wound swab samples were collected from diabetic foot patients from different hospitals in Alexandria, Egypt. Through phenotypic detection of biofilm formation, 93% (40) of the 43 P. aeruginosa isolates examined were categorized as biofilm producers. Molecular detection of the biofilm-encoding genes among the 43 P. aeruginosa isolates was as follows: algD (100%), pelF (88%) and pslD (49.7%), and this highlights a need for biofilm formation inhibitors to prevent the persistence of bacterial pathogens, and thus achieve better clinical outcomes in diabetic foot ulcer infections.
Conceptual solutions for control systems of differential tensioners for belt conveyors
Authors:   Bryansk State Technical University, Goncharov K.A.
Published: January 2022

Differential tensioning devices for belt conveyors in general and intermediate drives of extended conveyors in the form of closed traction loops are a new type of automatic tensioning devices that differ from other known designs by the presence of a stepwise discrete belt tension control system with separation of compensation functions for belt stretching under load and control of its tension during the operation of the conveyor in order to create optimal modes of belt loading. The article analyzes the well-known and practical concepts of belt conveyor control systems in general. The possibility of controlling the traction force realized by the intermediate belt drive by controlling the tension of the traction and load-carrying belts is shown. On the basis of the analysis, conceptual solutions for control systems for differential tensioning devices of belt conveyors are proposed with the possibility of both autonomous use and application in the structure of an integrated conveyor control system. Possible structures of linear parts of differential tensioning devices are presented, as well as options for the implementation of executive parts that directly move tensioning elements.

Published: January 2022

Defining measures for climate change adaptation is a complex task given the existence of social, environmental, and economic demands, particularly in cities with poor urban infrastructure. As a result of analyzing the revision process of the Recife Master Plan, it is possible to observe that a reduction in the social and environmental vulnerabilities has implied carrying out more consistent studies, which may entail the implementation of structuring measures, and that environmental sustainability requires multilevel governance, with policy reforms on a global, regional and local scale, difficult to implement in the short term, although necessary for refocusing climate policies and for overcoming the inability to provide resources for a tailored adaptation infrastructure. The path to building a resilient city that provides a safer environment for the future depends on an inclusive development model, which enables the population to improve urban conditions and minimize the impacts brought about by extreme weather events.

É complexa a tarefa de definir medidas de adaptação às mudanças climáticas diante da existência de demandas sociais, ambientais e econômicas, sobretudo em cidades que apresentam infraestrutura urbana deficiente. Como resultado da análise do processo de revisão do Plano Diretor do Recife (PDDR), vê-se que a redução das vulnerabilidades socioambientais implica a realização de estudos mais consistentes, que possam acarretar a implementação de medidas estruturadoras, e que a sustentabilidade ambiental demanda uma governança multinível, com reformas políticas em escala global, regional e local, de difícil aplicação no curto prazo, mas necessárias para reorientar as políticas do clima e superar a inabilidade de prover os recursos para uma infraestrutura adequada à adaptação. O caminho para construir uma cidade resiliente, que proporcione um ambiente mais seguro para as futuras gerações, depende de um modelo de desenvolvimento inclusivo, que permita melhorar as condições urbanas para a população e minimizar os impactos ocasionados pelos eventos climáticos extremos.

Authors: Yousif Araz M , Ismail Parween A , Ismail Narmeen A , Ismail Namam A
Published: January 2022

Objectives: To assess the serum indicators level in healthy and periodontitis subjects and correlate the levels in the terms of changes of serum and salivary parameters in periodontal disease. Methods: The assay comprised 85 subjects, enrolled of both genders in the age range of 33-56 years old. Volunteers were categorized into two groups: 40 healthy individual, other groups (periodontal disease) embraced 45 patients. The salivary and blood samples were collected and sent for biochemical analysis to measure the nitric oxide (NO), superoxide dismutase (SOD), glutathione, catalase, Interleukin 6 (IL-6), Interleukin 4 (IL-4), and interferon-Î³ (IFN-Î³) levels in periodontitis patients. Results: Based on the statistical evaluation of bio-indicator parameters, the following conclusion can be shown from this revision: Serum and saliva SOD (P <0.001), glutathione(P <0.001), and catalase(P <0.001) activates were significantly reduced in periodontitis as compared with control groups, the remaining biochemical assessed in periodontitis patients [NO (P <0.001), IL-4 (P <0.0001), IL-6 (P <0.0001), and IFN-Î³ (P <0.0001)] indicated significantly high levels  in both serum and saliva samples. Conclusions: The NO, SOD, catalase, glutathione and cytokines may be used as bio-indicator for periodontitis exposure, medical conduct and severity. This recognition offers early diagnosis of disease and progression. Also there was a direct positive correlation between the salivary and the serum bio-markers levels, which it was proved that the salivary non-invasive examination had a significant association with the serum investigation.
QuantumCumulants.jl: A Julia framework for generalized mean-field equations in open quantum systems
Authors: Plankensteiner David , Hotter Christoph , Ritsch Helmut
Published: January 2022

A full quantum mechanical treatment of open quantum systems via a Master equation is often limited by the size of the underlying Hilbert space. As an alternative, the dynamics can also be formulated in terms of systems of coupled differential equations for operators in the Heisenberg picture. This typically leads to an infinite hierarchy of equations for products of operators. A well-established approach to truncate this infinite set at the level of expectation values is to neglect quantum correlations of high order. This is systematically realized with a so-called cumulant expansion, which decomposes expectation values of operator products into products of a given lower order, leading to a closed set of equations. Here we present an open-source framework that fully automizes this approach: first, the equations of motion of operators up to a desired order are derived symbolically using predefined canonical commutation relations. Next, the resulting equations for the expectation values are expanded employing the cumulant expansion approach, where moments up to a chosen order specified by the user are included. Finally, a numerical solution can be directly obtained from the symbolic equations. After reviewing the theory we present the framework and showcase its usefulness in a few example problems.

Published: January 2022

The Covid-19 pandemic has changed the daily routine of work. Since the issuance of PP Number 21 of 2020 concerning Large-Scale Social Restrictions, activities in public places or public facilities have been limited with the aim of reducing the spread of Covid-19. Likewise with the learning process, the Covid-19 pandemic has changed the conventional face-to-face learning pattern to face-to-face online. Therefore, this study aims to determine how effective online learning is at UIN Ar-Raniry Banda Aceh. The research method used in this study is a qualitative method with a descriptive approach with observation, interviews and documentation techniques. The research subjects are LPM UIN Ar-Raniry as policy makers as well as lecturers and students at UIN Ar-Raniry as implementers of online learning. The results of this study indicate that online learning at UIN Ar-Raniry Banda Aceh has not been effective, but to achieve this effectiveness the campus has tried as much as possible by doing several things, namely before the implementation of online learning activities the campus first designed planning and survey conditions and training to lecturers, then formulate policies, formulate goals and strategies, determine facilities and supervision which is carried out routinely through the Siakad portal.

Purpose: Acute bronchiolitis (AB)-related return visits incur overuse of emergency medicine resources, crowding of emergency departments (EDs), and deterioration of rapport with the guardians. The authors aimed to analyze factors associated with the return visits to the ED.Methods: This study was conducted based on the medical records of 447 children aged 24 months or younger with AB who visited the ED from January 2019 through December 2020. A return visit was defined as an AB-related visit to the ED within 7 days of index visit. According to the return visit, we compared the clinical features. Multivariable logistic regression was conducted to identify independent factors for the return visit.Results: Of the 323 children with AB, 77 (23.8%) made return visits. The returning children showed a younger median age (6 [interquartile range, 2-10] vs. 8 months [3-14]; P < 0.001), a lower mean oxyhemoglobin saturation (92.9 ± 4.3% vs. 97.1 ± 1.8%; P < 0.001), and higher frequencies of congenital heart diseases (22.1% vs. 10.6%; P = 0.009) and bronchopulmonary dysplasia (11.7% vs. 5.7%; P = 0.013), and respiratory syncytial virus infection (57.1% vs. 37.0%; P = 0.002). No other variables, such as the hospitalization rate, differed as per return visits. The factors associated with return visits were respiratory syncytial virus infection (adjusted odds ratio, 9.41; 95% confidence interval, 2.13-41.57), lower oxygen saturation (2.00; 1.64-2.43), and age younger than 3 months (1.25; 1.07-1.24).Conclusion: AB-related return visits may be associated with age younger than 3 months, lower oxygen saturation, and respiratory syncytial virus infection.
Surgical Robotics Systems for Deep Brain Neurosurgery
Authors: Nassief Andrew M. K.
Published: January 2022

Robotics systems designed for surgical applications such as
Neurosurgery, likely may need to implement synchronous communication in
real time and asynchronous learning. It will likely primarily be
oriented towards spatial imaging and 3D virtualization, various
communication protocols, and calibration settings in order to perform
optimal results. In regards to computation, it needs to be heavily fault
tolerant in operation. It also needs to be aware of false positives.
Likely a complex deep brain surgical robotics system would implement
variations of brain mapping technology and may utilize
topological neuroanatomy. Various technologies in regards to the mapping
of the brain, visualization, robotics and mechatronics systems would
need to be in place. This paper is to look at the sciences through a
theoretical and conceptual process. This isn’t FDA reviewed for medical
accuracy and is meant to warrant a theoretical paper where information
is “as-is”. This will hopefully provide a bleuprint for continuing
research later on.
Challenges in Predictive Modeling of Single Pass Tangential Flow Filtration for Continuous Biomanufacturing
Authors: Fuchs Madeline , Bhawnani Rajan , Sripada Sobhana Alekhya , Molek Jessica , Ghodbane Mehdi
Published: January 2022

Opportunities for process intensification and increased productivity
have made the field of Continuous Biomanufacturing an area of high
interest and active research. Within the purification train of producing
biologics, Tangential Flow Filtration (TFF) is typically employed after
chromatographic separations, to increase drug substance concentration,
making the process more economical and further meeting dosage
specifications. In a batch operation, concentration occurs via
recirculation of the feed material where desired output concentration is
attained through multiple pump-passes over the TFF membrane, while
steadily excluding the buffer. Single-Pass Tangential Flow Filtration
(SPTFF) enables continuity of this process by achieving similar
concentration factors through a single – pass over these membranes
while operating at low feed flow rates. Our work elucidates the
development of a mechanistic process model to predict SPTFF performance
across a relatively wide design space using a first principles approach.
The developed model is found to be accurate for a range of high feed
flow rates but is inaccurate at flow rates below 25 L/m2/hr. At very low
flow rates, small differences in the mass transfer coefficient have been
observed to significantly alter the prediction of the retentate
concentration. We thus describe the challenges in predictive process
modeling of SPTFF in antibody biomanufacturing.
The inverse minisum circle location problem
Authors: Gholami Mehraneh , Fathali Jafar
Published: January 2022

Let n weighted points be given in the plane. The inverse version of the minisum circle location problem deals with modifying the weights of points with minimum cost, such that the sum of the weighted distances from the circumference of a given circle C with radius r, to the given points is minimized. The classical model of this problem contains infinite constraints. In this paper, a mathematical model with finite constraints is presented. Then an efficient method is developed for solving this problem.

BELEZA E MODA DA MULHER REPRESENTADAS NA IMPRENSA FEMININA DOS SÉCULOS XX E XXI
Authors: Nogueira Joani Almeida dos Santos , Silva Daiane Lopes da
Published: January 2022

Neste artigo, investigamos revistas produzidas entre os séculos XX e XXI e a maneira como as mulheres são representadas. Nosso estudo está voltado para cinco publicações: Jornal das Moças (1914); Revista Feminina (1936); Querida (1968); Capricho (1999); Vogue Brasil (2018). Para a presente análise, temos o entrelaçamento entre duas áreas científicas, História e Linguística que resultaram na História das Ideias Linguísticas. Esse estudo, ainda que fragmentado, pois fizemos um breve recorte de diferentes materiais ao longo de dois séculos, possibilita a verificação e conhecimento historiográfico com o auxílio dessas fontes e demonstra um novo olhar sobre a História, distinta daquela que valorizava apenas figuras heroicas, os grandes feitos por elas e as realizações julgadas como importantes. Desse modo, constatamos o postulado por Chartier (1990, p.16-17), precursor da ideia que defende a maneira “como, em diferentes lugares e momentos, uma determinada realidade social é construída e dada a ler”.
