Teledentistry and Digital Therapeutics (DTx) for dentistry

Published on: 5th August, 2022

Due to the global pandemic spread of COVID-19, the medical field has experienced many changes [1]. One of the main changes is the attention to Telemedicine (Digital Medicine), which is a part of Digital Health. The combination of ‘Digital’ and ‘Dentistry’ can be awkward because dental treatment is often conducted face-to-face with clinical treatment, but it is planned to proceed with the inevitable flow of the times [2,3]. In addition, Digital therapeutics (DTx), a part of digital dentistry, is a narrower concept and has an evidence-based effect on diseases. This article contains opinions on the concept and current status of Teledentistry and the application of DTx [4].

The factors associated with mental health and the impact of COVID-19

Published on: 11th August, 2022

OCLC Number/Unique Identifier: 9591348162

The mental health impact caused by COVID-19 on adolescents was reviewed, and due to limited data, adult results were included, to support our assertion that additional mental health resources are needed for both adult and young people. Positive gains would include improved socio-emotional skills, a decrease in maladaptive behaviors contributing to the disruption in interpersonal relationships and lifetime achievements, suicide attempts and psychopathology, persistent mental health concerns found in the juvenile justice and foster care systems and substance use addiction later in adulthood (The American Psychological Association, 2019; Garber & Weersing, 2010; Office of Juvenile Justice and Delinquency Prevention, n.d.; Tomasello, 2018;). Geiger & Davis, 2019, found that 13% or 3.2 million United States (U.S.) teenagers aged 12 - 17 years old experienced at least one major depressive episode with the depression rate increasing 59% from 2007 to 2017. Therefore, we assert that developing programs to overcome barriers to mental health aid can reduce instances experienced in adolescence and adulthood.

Nephrotic syndrome in children during the COVID-19 pandemic

Published on: 23rd August, 2022

OCLC Number/Unique Identifier: 9597893068

The COVID-19 pandemic resulted in public health measures and fewer viral infections, which trigger the nephrotic syndrome. Our objectives were to characterize the effect of the COVID-19 pandemic on children with nephrotic syndrome. This single-center retrospective chart review compared children with nephrotic syndrome one year before the pandemic with the first wave of the pandemic. Epidemiologic events, clinical characteristics, and health care utilization were compared using paired t-tests, Fisher’s exact tests and Wilcoxon Rank Sum tests. Among 96 children the mean age was 10.7 ± 5.28 years. The distribution was minimal change disease (16.7%), focal segmental glomerulosclerosis (12.5%), membranous nephropathy (1%) and not biopsied (69.8%). Medication responsiveness was steroid-sensitive (25%), frequently relapsed (54%) and steroid-resistant (20.8%). There were 14 new diagnoses of nephrotic syndrome pre-pandemic and 18 during the pandemic. Fewer relapses during the pandemic were likely due to fewer viral illnesses from public health measures during the pandemic.

Status of hemodialysis patients using complementary and alternative medicine practices during the COVID-19 pandemic

Published on: 31st August, 2022

The use of complementary and alternative medicine (CAM) applications increased by 39.3% of individuals with chronic diseases during the pandemic process in Turkey. For this reason, this descriptive study was conducted to determine the use of integrative and integrated medicine practices in hemodialysis patients during the COVID-19 pandemic. The population of the study consisted of individuals who were treated in a hemodialysis unit in the city center (n = 235). It was planned to include whole of the population by using the whole number method, but patients, who did not agree to participate in the study and did not meet the inclusion criteria of the study, were excluded from the sample and the study was conducted with 160 patients between 1 June and 1 September 2021. As a data collection tool, a questionnaire consisting of 30 questions including socio-demographic and disease characteristics of the patients was prepared by the researcher upon review of related literature. Considering the distribution of phytotherapy method (herbal treatment) usage frequency of integrative and integrated medicine applications of individuals before the COVID-19 pandemic and during the COVID-19 pandemic period, the most vitamins (21.8%), prebiotics (12.5%), and honey (%) 10.6), their use was found to be high. During the COVID-19 pandemic, the use of massage (40%), breathing exercises (30.0%) and spiritual therapy (28.7%) applications increased. As a result, it is seen that integrative and integrated applications are considered in the process of dealing with hemodialysis patients. Physicians need to be aware of and ask patients about their use of integrated and integrated health practices.

Impact of coronavirus pandemic on safety and time of administration of subcutaneous immunotherapy among pediatric patients

Published on: 2nd September, 2022

OCLC Number/Unique Identifier: 9617323801

Introduction: Allergen immunotherapy is the only targeted therapy that can modify the natural course of allergic diseases. In pediatric patients, SCIT with aeroallergens is an effective treatment and should be considered as a preventive strategy in the treatment of allergic diseases, even though one of the major concerns about it is its safety. The main purposes of this study were to assess the safety of SCIT ultra-rush schedules with polymerized extracts in a pediatric population and to determine the impact of the COVID-19 pandemic on the safety and time of administration of subcutaneous immunotherapy among pediatric patients.Methods: A retrospective medical records review of patients under 18 years of age undergoing SCIT was made and re-scheduling due to restrictions imposed by the COVID-19 pandemic was recorded. Results: A total of 192 pediatric patients were included. Fifty-nine (31%) had local reactions and systemic reactions were not reported. In March 2020, the first case of COVID-19 was diagnosed in Portugal and all non-urgent appointments and procedures were postponed. In our group of pediatric patients, 43 (22%) were referred to primary care, 38 (20%) stopped AIT definitively and 111 (58%) maintained administrations in the hospital. Only 2 (2%) of them had reactions upon reinitiation. Conclusion: In this study, the ultra-rush protocol using polymerized extracts was safe in pediatric patients. Although the effectiveness of AIT may be compromised due to prolonged suspension of the treatment, it is important to note that despite longer interruptions, administrations may continue without compromising safety, maintaining shorter visits and a lower number of injections.

Published on: 2nd September, 2022

OCLC Number/Unique Identifier: 9617322423

The epidemic of COVID-19 was reported in Wuhan, China in December 2019 and turned into a national crisis, with infected individuals diagnosed all over China [1-3]. In early March 2020, the World Health Organization (WHO) declared that the Wuhan epidemic has turned into a global pandemic. Many European countries have started to know several cases affected by this coronavirus, which is known to be highly contagious. The WHO has launched several recommendations to curb the spread of this virus and to call the general confinement establishment in the affected countries.

SARS-CoV-2 Omicron and centaurus variants induced lymphocytopenia: A multicenter clinical investigation on 118,561 cases across Pakistan during 2021-2022

Published on: 16th September, 2022

The SARS-CoV-2 pandemic is still ongoing. Previously, several studies have been conducted to investigate laboratory markers as a tool for severity assessment during COVID-19 infections. Biological markers such as Platelet count, D-dimer and IL-6, Lymphocytopenia and others have been used for assessment of severity in COVID-19 disease patients (infected by SARS-CoV-2 Alpha, Beta, Gamma, Delta, Epsilon, and other variants). We observed a significant drop in lymphocyte count among suspected SARS-CoV-2 clinical patients with symptoms of fever, running nose, breathing discomfort, cough, and others during Omicron and Centaurus variants spread in Pakistan. A multicenter, cross-sectional study was conducted from Jan 2021 to Aug 2022, on 118,561 subjects to evaluate hematological abnormalities among suspected patients. Of note, significantly decreased lymphocyte levels (lymphocytopenia) were observed among 43.05% of infected patients. Also, the levels of NA (39.03%), HGB (28.27%), MCV (22.62%), PLT (8.17%), and ALB (4.30%) were also reduced among infected patients. This suggests that lymphopenia can be used as an alternative, cost-effective, early diagnostic biomarker for clinical COVID-19 patients, even before the diagnosis via real-time PCR. In resource-limited countries, the current study is critical for policy-making strategic organizations for prioritizing lymphocytopenia-based screening (as an alternative, cost-effective diagnostic test) in clinical COVID-19 patients, before real-time PCR-based diagnosis.

Monkeypox virus outbreak: A new threat of virus to mankind

Published on: 27th September, 2022

Viruses becoming day by day dominate over humans, as a covid-19 pandemic is not jet over, new monkeypox virus infection cases emerged in the month of May 2020. On 13th May 2020 WHO reported monkeypox virus cases from 12 member states that are epidemic for this virus. In the past monkeypox virus are rarely seen outside of west and central Africa. Investigations are going to establish a travel link between reported cases and epidemic areas. There are very little data regarding viral mechanism or time of shading and still, we have no licensed treatment. Two smallpox-approved drugs brincidofovir and tecovirimat have efficacy against monkeypox shown in animals. Now two smallpox-recommended vaccinations JYNNEOS and ACAM2000 are also available and are efficient to prevent the monkeypox virus. Two second- and third-generation Vaccinations are recommended by WHO for people that are immunocompromised and children’s MVA-BN, LC16. This article aims to raise awareness of virus spread, providing information regarding virus detail, severity, precautions, and detection.

Diagnostic evaluation of nasopharyngeal swab and saliva kits against SARS-CoV-2: Adequate rapid screening is deemed necessary to overcome COVID-19 Pandemic

Published on: 16th September, 2022

OCLC Number/Unique Identifier: 9625089265

SARS-CoV-2 is the virus associated with the disease called COVID-19 and become a global pandemic. The only way to prevent its severe scenarios is through timely and rapid testing. In comparison to more time taking gold-standard RT-PCR testing, rapid diagnostic kits are used. For better prevention and diagnosis of SARS-CoV-2, the analysis of rapid diagnostic kits' accuracy and specificity is necessary. This study is meant to assess and examine the viability, responsiveness, and explicitness of quick antigen distinguishing nasopharyngeal swabs (NPS), and saliva-based units. The study was conducted on 200 suspected COVID-19 patients from Islamabad, 100 of which were RT-PCR positive while 100 were RT-PCR negative. For the analysis of Rapid diagnostic COVID-19 kits (RDT), nasopharyngeal swabs (NPS) and saliva samples were taken from the RT-PCR positive and negative patients. Among 100 RT-PCR positive patients, 62% were males (19 - 91 years), 34% were females (20 - 78 years) and 4% were children (6 - 17 years). False-negative results were significantly more observed in saliva-based RDTs of the sample (49%) as compared to nasopharyngeal swab RDT (38%). There were 2% invalid results in saliva-based RDT and 3% invalid results in Nasopharyngeal swab RDT. While among 100 RT-PCR negative patients 69% were males (19 - 80 yrs), 27% were females (18 - 77 yrs) and 4% were children (12 - 16 yrs.). False positive results were significantly more in saliva-based RDT (22%) as compared to Nasopharyngeal swab RDT (13%). The sensitivity and specificity of saliva-based RDT were 67% and 87% respectively while that of Nasopharyngeal swab (NPS) was 72% and 82% respectively, both of which were less than the gold standard RT-PCR sensitivity demanding the introduction of more sensitive RDT kits in Pakistan for accurate detection of COVID-19.

A relevant article, white papers and other documents concerning the mRNA vaccine: an interesting collection useful to better understand some phenomena and to generate hypotesys

Published on: 13th October, 2022

The aim of this work is to report some interesting references and documents related to the mRNA vaccine. Every cited reference can act as an instrument to better understand what some independent researchers find: this work is mainly focused on the public debate related presence/absence of graphene derivates in some vaccine vials for COVID-19. Relevant classic articles White Papers or other kinds of a document are useful instruments to better clarify some crucial aspects of this infectious disease, its epidemiology and the efficacy of the measure adopted (preventive, therapeutic, or vaccine).If the reviewed article show an intrinsic recognized international value other kinds of source like a White Paper or other documents can be of interest to generate hypotheses or to open public discussion on crucial topics. For this reason, it is useful to use this method also in the discussion related to impurity profiles in new innovative bio-pharmaceuticals like the mRNA vaccine. The fact that this product was introduced with an emergency authorization, whit reduced the time of experimentation and due to the lack of official quality information related to some raw materials used authorizes us to use also this method.Even if the international official regulatory agency does not find this substance in the control for release of the lots it is interesting to more deeply investigate what funded by an independent researcher in some vials of vaccine or sample patient’s blood after vaccination. This reference even if not a smoking gun the same can stimulate the reasoning about the general concept involved. It is needed, to read this work, to consider the intrinsic limitation of some of the study research reported (White Paper) or the other documents.

COVID-19 pandemic to endemic

Published on: 7th November, 2022

The COVID-19 pandemic appeared in late 2019 and became a major health concern with rapid transmission and very high mortality rates across the globe. Although precautionary, preventive, protective and therapeutic measures have been adopted against COVID-19, still the disease has drastically affected people. In order to overcome the challenges of the pandemic, the understanding of the route of transmission, its fusion with receptors and invasion into the human body and hacking the immune system, the viral genome was sequenced. The viral genome keeps on mutating and altering its original form into its subtypes. Moreover, age and comorbid conditions had their impact on developing the disease differing from individual to individual due to interaction varying between the host genome and virus. Considering the pathogenesis of the virus, neutralizing antibodies reduced the viral impact and severity. This review is focused on highlighting the COVID-19 genome, host genetic factors, the pathogenesis of the disease and available therapeutic measures to overcome the pandemic.

Interdictory contribution of Vitamin D to prevent corona virus infections

Published on: 16th November, 2022

The impact of vitamin D on the musculoskeletal system is well known. The diverse role of vitamin D is well supported by the functionality of vitamin D receptors and vitamin D activating enzymes (hydroxylase) present in tissues and cells. Hypovitaminosis D causes rickets, osteomalacia, hyperparathyroidism, and an increased risk of bone fracture. Vitamin D has immune-stimulatory effects on both the innate and adaptive immune systems. Vitamin D induces antimicrobial peptide cathelicidin and defensin that can inhibit viral replication of pro-inflammatory cytokines that regulate inflammatory encasement. Moreover, several studies on vitamin D have shown its interdictory role in the immune and respiratory systems. This global crisis, the COVID-19 pandemic condition has increased the risk of acute respiratory tract infection by immune dysregulation along with cytokine storm, which further progress into acute respiratory distress syndrome. Vitamin D has immunomodulatory and anti-inflammatory properties which are effective against respiratory viral infections. Vitamin D supplementation has shown a compatible effect on viral infection. This review article discusses the role of vitamin D in reducing the risk of respiratory infections including the severity of COVID-19 infections. This review focuses on the therapeutic role of vitamin D to improve clinical outcome during COVID-19 infection and suggest its possible role in the prevention and treatment of respiratory infections.

SARS-CoV-2 antibody response to third dose vaccination in a healthy cohort

Published on: 23rd November, 2022

Determining the extent of immunity induced by booster doses of COVID-19 vaccinations is crucial for informing recommendations for booster dose regimens as well as constant adjustments of immunization strategies amongst different groups of people within the population. The study involved 31 healthy volunteers (majority were healthcare professionals) who completed either vaccination course with Pfizer or Moderna mRNA vaccines and received a third dose of the vaccine. Here we report results on the evaluation of an antibody response to four different SARS-CoV-2 antigens: RBD, S1, S2 and nucleocapsid prior to third dose and two and four weeks after a booster vaccination. We detected a peak of high titers of antibodies after the third dose with a gradual decline after four weeks. No significant differences were seen between the two vaccines in terms of antibody response. There were no gender discrepancies between the two vaccines. Our results suggest that: third doses are necessary due to the emergence of different SARS-CoV-2 variants and postvaccination antibody testing continues be essential in determining possible standardization of SARS-CoV-2 vaccines regimens.

Ecology of vital activity as an element of antistress therapy on the example of the organization of the work of a medical center with industrial enterprises under the VMI program

Published on: 29th November, 2022

The pandemic the new Coronavirus infection has brought changes in the health status of a large number of our citizens. The consequence of this has been a higher rate of employees seeking medical care and subsequent sick leave. Crisis phenomena in the economic and social life of society are associated with the consequences of the pandemic, moreover, the stress burden on the population increases with the consequences of the pandemic. All this affects the level of performance. The transferred COVID-19 has increased the number of patients with complaints of pain in joints and muscles, with the phenomena of cardiovascular pathology, as well as in breathing, increased frequency of asthma attacks, etc. That is, complications affected a wide range of diseases [1-4]. All this is the consequence, including neurological pathology, which is closely related to stress. According to surveys of several large industrial enterprises, 31.7% of those seeking medical help report anxiety, sleep problems, and a feeling of fatigue [5]. Exacerbation of chronic diseases was recorded in more than 50% of patients with COVID-19. The figures show that more than 1/3 of the population is chronically unwell, and more often than usual they apply for sick leave, which inevitably leads to a decrease in economic indicators [6-10].

The necessity of emotion management for the general public: a comparison of diagnostic changes in two anger-related psychiatric disorders

Published on: 23rd December, 2022

Although emotion management is essential to mental health, public health has not paid much attention to emotional conditions or disorders. By analyzing a nine-year diagnostic trend and sociodemographic characteristics of two mental disorders: Hwabyung and Intermittent Explosive Disorder (IED), this study demonstrated the importance of managing emotions precautionarily.Data reconstructed from the National Health Insurance Service were used to analyze the yearly diagnostic trend in the two mental disorders characterized by anger.Hwabyung was more common among women and middle-aged individuals, despite the varied number of diagnoses by year. Between 2010 and 2018, IED diagnoses gradually rose, with the average rate of increase the highest in the 20s for male IED diagnoses in 2017. The low prevalence of the IED in Korea compared to other Western countries and the gender and age differences in both Hwabyung and IED diagnoses suggest the role of cultural influences related to emotions (or emotional management).Especially in light of the world’s emphasis on resilience to COVID-19, these results indicate how public emotional management is essential during stressful situations. The results also highlight the need for community mental health programs tailored to gender and age.

The role of health sectors in the fighting misconception of COVID-19 vaccine

Published on: 27th December, 2022

In the long run people around the globe particularly those who live in underdeveloped Countries in Africa, especially in Ethiopia a large number of communities has a misconception that disease may be transmitted by utilizing health service due to a lack of trust in health service delivery system, Most of the population strongly related with religion, they claimed that it is sin or God or Allah driven. According to a health behavior model, knowledge and practice are contributing factors for increasing healthcare seeking among patients with low levels of trust [1,2].

Case report: contrast imaging in the setting of venous thrombosis

Published on: 28th February, 2023

Disruption to contrast agent supply chains for radiology investigations has become an additional consequence of the COVID-19 pandemic. Various recommendations, including dose reductions and choices of alternative agents, have been made to help account for this limited availability. This case demonstrated how two separate CT venograms with different contrast agents, undertaken on the same day for the same patient, yielded different results; venous thromboses were more prominent in the subsequent scan. Although there was some evidence of venous sinus thrombosis on the first scan, repeat imaging was required to further characterize the lesions identified. The case exemplifies the notion that diagnostic imaging should always be guided by a detailed history and examination. It also raises the discussion point of whether more strict or uniform protocols should be developed to facilitate contrast administration for radiology investigations. It is important that appropriate doses are always administered to maximize diagnostic yield.

Published on: 4th March, 2023

Background: The clinical manifestations of Corona Virus Disease of 2019 (COVID-19) varied from patient to patient with evidence of multi-organ involvement. Many patients continue to have a wide range of symptoms for variable periods of time. The long-term effects of COVID-19 infection (post-COVID-19 illness or syndrome) are not yet been fully explored.This study aims to highlight the clinical manifestations of the acute COVID-19 infection and the longer-term manifestations of the disease among the attendants to a private GP clinic in the Urban Amman Area, Jordan.Methods: A clinical case-series study was conducted on a sample of 300 COVID-19-positive cases among patients attending my private GP clinic in the Urban Amman Area, Jordan. We used the structured questionnaire based mainly on World Health Organization (WHO) Case Report Form (CRF) verified tool for post-COVID-19. All patients with COVID-19 were included in the study. Data collection was conducted through phone calls and analyzed using the Statistical Package for Social Sciences (SPSS) software. Results: The incidence of COVID-19 among patients attending the clinic during the period of this study was 25%. Females were 135 (45%) of the study population and males were 165 (55%). The mean (SD) of age was 34.2 (5.0) years. Most of the infected staff (90%) were symptomatic and developed acute COVID-19 symptoms. Fever, Cough, Fatigue, joint pain and loss of smell and taste were the most common symptoms. 72% of the study population had fully recovered from the infection, while 28% of them continued to suffer from many long symptoms. Fatigue (28%), shortness of breath on activity (18%), Social withdrawal (18%), anxiety (17%), forgetfulness (16%), trouble concentrating (15) and depressed mood (14%) were the most frequently reported long symptoms.Conclusion: The prevalence of Post COVID-19 illness was 28% with a high public health burden calling for the public health system to address the medical and psychological needs of affected persons. Mental health and psychosocial support are recommended elements for the management of patients.

Training networks preparation for the era of COVID-19

Published on: 4th April, 2023

In administrative and economic science, factor analysis models are essential for their explanatory capacity of institutional responses to risk events. The objective of this document was to contrast a model that explains the emergence of corporate governance dimensions in the face of the pandemic. An exploratory study was carried out based on a systematic review of the literature from 2020 to 2023, considering the search by keywords in Google scholar and Microsoft academic, as well as the judges from a public university in the center of Mexico. The results show that corporate identity explains the university’s response to the pandemic. In relation to the state of the art, the scope and limits of the model are discussed in other proposals.
