Managing the menopause during the pandemic

The structure of the presentation will be 1) Pandemic-Epidemiology 2) General Pandemic-Management 3) HRT and COVID 4) Different spectrum of menopausal symptoms (Europe/Asia) 5) Different risks lead to different HRT. 1) Pandemic-Epidemiology: SARS-COVID-19 has got to be a new disease, China was the first to suffer from the pandemic starting in December 2019 with spread all over the world. Diagnosis, treatment and protective measures have started in Europe in March 2020;up from autumn 2022 in Europe the pandemic changed to endemic, but protective measures still should be continued in risk patients like in hospitals and nursing homes. Rehabilitation will for long-time be an issue like treatment of "Post-" and "Long-COVID". China pursued a zero-COVID-policy until Dec 2022. The sudden stop of almost all measures led to a sharp increase in infections, which shows that the disease will remain a global risk. 2) General Pandemic-Management: Protective measures like vaccination, surgical masks, screening/testing, isolation management, travel/residence history in high-risk regions, education of patients and families had to be the first priority, ahead of other issues such as the management of menopause. 3) HRT and COVID: Already the first prelimary data assessed in Wuhan/China have shown that women with low estradiol-levels had more severe infections with COVID. An analysis of health records of 68,466 COVID-positive patients from 17 countries showed that the fatality risk for women > 50 years receiving HRT was reduced by more than 50% compared to those women not taking HRT (Seeland, 2020). Likewise from a case-control study analyzing the self-reported data of 1.6 million UK menopausal women through the COVID-Symptoms Study Smartphone application (control populations adjusted for age, body mass index, and smoking status) was concluded, that HRT not only can be used, but even can protect from COVID-infections and/or their sequelae (Costeira, 2021). 4) The different spectrum of menopausal symptoms (independent of COVID-infections) comparing data in Europe (showing more vasomotor symptoms) and China (more somatic symptoms) will be presented, including own data. 5) Different risks during HRT consequently lead to different use of HRT, especially more transdermal estrogen combined with progesterone in Europe due to much higher VTE-risk, but more management of the high bleeding-problems in China using individualized (mostly oral) estrogen/progestogen combinations.

Assessment of COVID-19 Control and Prevention Measures in Student Dormitories at Mazandaran University of Medical Sciences, 2021.

Background and purpose: Adherence to the principles of personal protection and commitment to health guidelines and principles of prevention perform important roles in controlling COVID-19 in a community. In this re3search we studied necessary measures to prevent COVID-19 in university dormitories at Mazandaran University of Medical Sciences, 2021. Material(s) and Method(s): In this descriptive-analytical study, 114 students in active dormitories during the COVID-19 pandemic participated in an online survey and their views and knowledge about COVID-19 preventive measures in the dormitories were examined. The samples were recruited using census method and data were analyzed in SPSS. Result(s): The results of the Chi-square test showed a significant relationship between adherence to preventive measures and educational level (P=0.015). Following personal hygiene was found to be significantly different according to being a local student, having underlying diseases, and the number of students at rooms (P<0.05). Findings showed that physical distancing and screening had no significant relationship with any of the variables studied (P>0.05). Conclusion(s): The study showed that among the four areas investigated, personal hygiene practices and following the principles of prevention of COVID-19 were in a good condition, while physical distancing and screening were not satisfying. Therefore, university authorities should make serious changes to improve these issues at dormitories.Copyright © 2023, Mazandaran University of Medical Sciences. All rights reserved.

Measuring the impact of the COVID-19 pandemic on breast cancer screening in Puerto Rico

Introduction: The COVID-19 pandemic has caused major changes to healthcare services, especially those related to early detection and screening practices like breast cancer. In Puerto Rico, breast cancer is the main cause of death, representing 18.9% of cancer deaths in women, making early detection even more important to prevent morbidity and mortality. This study aims to describe the impact of COVID-19 on breast cancer screening and assess differences in health utilization by age group and health regions in Puerto Rico. Method(s): This study used data on breast cancer screening medical claims from Puerto Rico Track, a project in collaboration with the Puerto Rico Public Health System and the Puerto Rico Institute of Statistics that aims to assess health access and utilization patterns in Puerto Rico. Claims including unilateral and bilateral mammography, sonommamography, and MRI were analyzed. Descriptive statistics and percentual changes between the COVID-19 baseline year (2016) compared with 2020 and 2021 were performed (overall, by age-group and health region). Result(s): A total of 193,793 screening tests were performed in 2016, compared to 66,463 in 2020, and 89,322 in 2021. Overall, a third of the medical claims for breast cancer screening (33.2%) were in the age group of 51-60 years. An overall decreasing percentual change was observed comparing 2016 vs. 2020 (65.7%), where the age group with the broadest gap reduction were among women 41-50 years old (68.2%). When comparing medical claims of 2016 (193,750) versus 2021 (89,320) (pre and post pandemic), an important decreasing change (53.9%) was observed. The age group with the highest decrease comparing 2016 to 2021 was the 41-50 years one (68.2%). The Western region of Mayaguez/Aguadilla had the highest decreasing percentual change, with a reduction of 73.6% in 2020 compared to 2016, and 62.6% when compared 2021 with 2016. Conclusion(s): Breast cancer screening was notably affected by the COVID-19 pandemic in Puerto Rico. A pattern of decreasing breast cancer screening was observed by health regions and by age. These efforts provide evidence of the need of tailored evidence-based interventions to increase breast cancer screening in the island.

GlycoEVLR: Glycosylated extracellular vesicle-like receptors for targeting and sensing viral antigen

Biosensors are rapid and portable detection devices with great potential for the instant screening of infectious diseases. Receptors are the critical element of biosensors. They determine the specificity, sensitivity and stability. However, current receptors are mainly limited to antibodies and aptamers. Herein, we developed a glycosylated extracellular vesicle-like receptor (GlycoEVLR) for the rapid detection of virus antigens, specifically using SARS-CoV-2 as a model. The human angiotensin-converting enzyme 2 (ACE2)-overexpressed and heparin-functionalized HEK-293T cell membrane-cloaked Fe3O4 nanoparticles (NPs) were prepared as functionalizing GlycoEVLR. They were characterized as spherical core–shell structures with a diameter of around 100 nm, which were perfectly comparable to natural extracellular vesicles. Binding affinities between GlycoEVLR and spike1 (S1) antigen were demonstrated using surface plasmon resonance (SPR). The GlycoEVLR was fixed on magnetic electrodes to construct electrochemical biosensors. Using electrochemical impedance spectroscopy (EIS) as a measurement technique, the S1 antigen was detected down to 1 pg/mL within 20 min and showed a good linearity range from 1 pg/mL to 1 ng/mL. Also, the GlycoEVLR-based electrochemical biosensors showed excellent antifouling performance and stability. Overall, our work provides a useful methodology for developing extracellular vesicle-like receptors for biosensors. Combining the inherit natural receptor proteins and antifouling lipids from the host cells with engineered glycan motifs to target and sense viral antigens will open a newavenue for biosensors.

Results of screening examination of employees of a medical hospital for antibodies to SARS-CoV-2

While providing medical care to patients with a new coronavirus infection, medical workers are at risk of developing COVID-19 significantly more often than the general population. In addition to morbidity risks, an important question is the duration of the immune response to COVID-19. The aim of our study is to assess the incidence of COVID-19 and the duration of the persistence of anti-SARS-CoV-2 antibodies among hospital medical staff. Material and methods. We conducted a retrospective non-randomized single-center study, based on the analysis of the laboratory database of the Municipal Clinical Hospital No. 52 (Moscow). The results of the 2160 employees were included into analysis. The inclusion criteria were as follows: at least one result of antibody determination to SARS-CoV-2 in period from June 2020 to January 2021;the date of the last antibody determination to SARS-CoV-2 no earlier than November 1, 2020. Additionally, a group of 100 employees were selected for further investigation of the persistence of immunoglobulin G (IgG) antibodies to SARS-CoV-2. Additionally, a group of 100 employees was selected, who had a confirmed fact of seroconversion for IgG and the presence of at least three results of IgG to SARS-CoV-2 determination with an interval of at least 4 weeks. Results. According to IgG determination results, by January 2021, 66.6% of all hospital employees have already been ill with COVID-19. The medical staff who worked with patients with COVID-19 been ill with COVID-19 in 78.2% of cases. The share of sick medical personnel who did not work with this group of patients was 55.3%. The first termination of antibodies persistence to SARS-CoV-2 from employees was marked from 3-4 months of observation. After 7-9 months, 23% of the observed group became seronegative. Odds ratio for the risk of COVID-19 for medical staff, who worked with COVID-19 patients was 2.89 (95% CI 2.34-3.56) to other medical staff and 3.6 (95% CI 2.82-4.59) to non-medical staff. Conclusion. The incidence of COVID-19 and the risk of infection among medical workers is significantly higher than among the general population, which dictates the need of further improvement of COVID-19 prevention measures among medical workers.Copyright © 2022 by the authors.

Current situation and prospect of teleophthalmology.

With the development of technology, doctors can diagnose and treat many diseases through telemedicine. At present, teleophthalmology is mainly used in screening and diagnosing some ocular diseases, monitoring chronic ocular diseases, as well as teleconsultation. With the increasing demand and application of teleophthalmology, some problems will gradually become prominent, such as insufficient equipment and staff, medical risks, patient acceptance and satisfaction, network security, privacy, and covering of medical insurance. The global pandemic of COViD-19 has unexpectedly brought telemedicine to the forefront of ophthalmic services, and may continue to change the way of ophthalmic diagnosis and treatment. With the development of artificial intelligence technology, the expansion of 5G communication network coverage, the standardized training of primary medical staff, and the introduction of relevant laws and regulations, teleophthalmology will become more improved, universal, and widely applied, so as to provide patients with sustainable medical services of higher quality.Copyright © 2021, Peking Union Medical College Hospital.

Inflammatory Profiles Are Associated with Long Covid 6 Months after Illness Onset

Background: Systemic hyperinflammation is key to the pathogenesis of severe, acute COVID-19. However, few studies have analysed inflammatory profiles in adults with mild/moderate COVID-19, or in those with post-acute sequelae of COVID-19 (PASC). We aimed to i) describe trajectories of cytokines in a prospective cohort of adults with mild to severe COVID-19, compared to uninfected, healthy controls and ii) identify early (< 4 weeks after illness onset onset) predictors of ongoing PASC and inflammation at 6 months after illness onset. Method(s): RECoVERED is a prospective cohort of adults with laboratoryconfirmed SARS-CoV-2 infection between May 2020 and June 2021 in Amsterdam, the Netherlands. Serum was collected at weeks 4, 12 and 24. Participants completed monthly symptom questionnaires. PASC was defined as having at least one ongoing symptom that originated < 1 month of illness onset. Cytokine concentrations were analysed by human magnetic Luminex screening assay. We performed random forest regression to identify early predictors of PASC and raised CRP/IL-6 at 24 weeks, using Shapley additive explanation values as measures of importance for the different predictors. Result(s): Of 349 RECoVERED participants, 186 (53%) had >=2 serum samples and were included in current analyses. Of these, 101 (54%: 45/101 [45%] female, median age 55 years [IQR=45-64]) reported PASC at 12 weeks after illness onset, of whom none recovered by 24 weeks. We included 37 uninfected controls (17/37 [46%] female, median age 49 years [IQR=40-56]). At 4 weeks after illness onset, levels of IP10, IL10, IL17, IL1beta, IL6 and TNFalpha were significantly elevated among participants infected with SARS-CoV-2 compared to controls. Ongoing PASC was independently associated with raised CRP at 24 weeks. Early raised IL1beta and sCD14 levels and greater BMI at illness onset were the strongest predictors of PASC at 24 weeks. Those with higher early sCD14 or IL1beta and TNFalpha levels were also more likely to have persistently raised CRP and IL6, respectively, at 24 weeks (Fig.1). Conclusion(s): Differences in cytokine concentrations between individuals with COVID-19 and uninfected controls largely were greatest < 4 weeks after illness onset. In our study, ongoing PASC was associated with persistently elevated CRP at 24 weeks. Early immune dysregulation was, alongside BMI, an important determinant for persistent PASC. Further investigation of individuals with PASC and long-term aberrant cytokine levels may help improve our understanding of the condition. (Figure Presented).

Prevalence of substance use in adults with cystic fibrosis

Background: Substance use is an understudied aspect of cystic fibrosis (CF) care. Even casual use of drugs or alcohol may reduce compliance with complicated treatment plans, worsen existing conditions associated with CF, or cause potential drug interactions. To understand the need for mitigation mechanisms for risky substance use in a CF population, we studied the prevalence of substance use in our adult CF clinic population to characterize relationships between substance use and health status. Method(s): In our large academic CF center, we performed a retrospective chart ion of 420 patients over a 6-year period (2015-2021). Clinical staff annually administer the Drug Abuse Screening Test (DAST-10), Alcohol Use Disorders Identification Test (AUDIT), Patient Health Questionnaire (PHQ-9), and General Anxiety Disorder (GAD-7) to assess drug use, alcohol use, depression, and anxiety symptoms, respectively. Demographic characteristics, lung function (percentage predicted forced expiratory volume in 1 second (FEV1pp)), and anxiety and depression symptom screening scores were recorded. Because substance use can change over time, we counted each assessment date as an independent observation (n = 1434). The chi-square test (Table 1) was conducted in R/RStudio [1] to assess for associations between self-reported substance use and symptoms of depression and anxiety. Because of insufficient data, aggregate datawere used to describe the presence (PHQ-9 or GAD-7 >= 10) or absence (PHQ-9 or GAD-7 < 10) of symptoms of depression and anxiety. Result(s): Positive scores for risky use were defined as a DAST score of 1 or higher and an AUDIT score of 8 or hither. Eighty-three of 326 patients (25%) met criteria for risky substance use on at least one observation. Therewas a slight male predominance (54.2%) and wide age distribution (mean age 30 +/- 7, range 20-55);Thirty (36.1%) had a higher AUDIT score, 34 (40.9%) had a high DAST score, and 19 (22.9%) had high scores on both.We selected 2019 to evaluate single-year prevalence of positive screenings to avoid the impact of COVID. In 2019, 29 patients had at least one positive screening result (DAST,15/203, 7.3%;AUDIT, 24/193,12%;both,10/193, 5.2%). In the 6- year dataset, we did not find a statistically significant association between symptoms of depression and anxiety and indication of drug or alcohol use in self-reported users (355 observations). Conclusion(s): According to a 2020 national survey of healthy Americans, 20.8% have used illicit drugs at least once in the past year, and 10.2% meet criteria for alcohol use disorder [2], compared with 7.3% of patients in our 2019 data who have used drugs (n = 15) and 12% (n = 24) who indicated risky alcohol use. In this review, positive screening scores on the DAST and AUDIT were not associated with degree of symptoms of depression and anxiety, suggesting that substance use and symptoms of depression and anxiety were not temporally associated with each other. Future work will include analysis of the relationship between substance use and mental health in the larger University of North Carolina clinic population and linear regression to evaluate possible explanatory variables for substance use in this populationCopyright © 2022, European Cystic Fibrosis Society.

Cervical Cancer Prevention: The Role of the Nurse and Medical Care in Primary and Secondary Cancer Prevention

Objective: Although these days the priority is to fight the Covid-19 pandemic, the importance of human papillomavirus (HPV) infection is not to be neglected. Mechanism: Cervical cancer is caused mainly by a chronic infection with one or more of the high-risk subtypes of HPV -most commonly a sexually transmitted disease acquired early in life. Most HPV infections go away on their own, but some can lead to a precancerous state that, if left untreated, can undergo complete neoplastic transformation. Findings in Brief: There is a hope that in the future the combination of screening tests with vaccinations against oncogenic strains of HPV will allow reductions in the percentage of those contracting cervical cancer. Conclusion(s): The importance of educational activities should be emphasized in developmental gynecology in the context of oncological prevention. The roles of both doctors and nurses are important here. During the Covid-19 Pandemic, these kinds of activities are not to be abandoned. In addition, efforts should be made to develop more practical and workable HPV and cervical screening strategies for use during a pandemic.Copyright © 2022 The Author(s). Published by IMR Press.

Evaluation of Urine L-FABP Point of Care Kit in the Philippines as Predictive Marker of Clinical Severity of COVID-19 (EPOCH COVID study)

Background: The search for simple clinical and laboratory markers to help predict the clinical severity of patients presenting with COVID-19 has prompted this study to look at the predictive value of urine L-FABP (Liver Type-Fatty Acid Binding Protein) point-of-care test kit at the initial presentation of COVID-19 patients to the hospital. Method(s): The validation study prospectively included 109 consecutive patients with mild to moderate COVID-19, mean age of 52.2 years (range 19-84) presenting at the Emergency Rooms of 4 participating Metro-Manila hospitals from February to April 2021, with available data for analysis for 103 patients. Urine L-FABP POC (Point-of-Care) test and other clinical parameters and the level of severity of COVID-19 were determined at Day 0, Day 4 and Day 7. Computations for Sensitivity, Specificity, Positive and Negative Predictive values and Likelihood ratios were performed Results: Twenty-three patients tested positive for urine L-FABP, out of the 103 patients analyzed, while 80 tested negative. Of the 23 patients who tested positive for urine L-FABP, 6 has progressed in severity, while 17 did not progressed. Of the 80 patients who tested negative for urine L-FABP, 13 progressed, while 67 did not progressed in severity. Giving a Sensitivity of 31.58%, Specificity of 79.76%, Positive predictive value of 26.09%, Negative predictive value of 83.75%. Combining urine L-FABP and initial clinical parameters like SIRS (Systemic Inflammatory Response Syndrome) criteria to predict progression of severity yielded a higher Specificity of 91.67 % and Negative Predictive value of 84.62%. Conclusion(s): The study shows the utility of initial urine L-FABP POC test as a negative screening test in triaging adult patients presenting to the ER with mild to moderate COVID-19. Patients at the ER with a negative urine L-FABP test, will most likely not progressed to severe COVID-19. Combining clinical parameters like SIRS Criteria with the urine L-FABP result can increase the negative predictive value.Copyright © The PHILIPPINE JOURNAL OF INTERNAL MEDICINE is a peer reviewed journal and a copyrighted publication of the Philippine College of Physicians.

Point-of-Care Sensors in Clinical Environments

Thanks to a general multidisciplinary and interdisciplinary approach, during the last few decades there have been huge advances in the diagnostic field. In particular, the miniaturization and automation of several assays have led to the development of the so-called point-of-care tests (PoCT), which are devices capable to provide accurate and specific detection of analytes such as glucose, other clinically-relevant biomarkers, pathogens, and drugs. The detection with these devices typically takes place in a few minutes and without the need of specialized personnel. Here we discuss the key technologies and applications of PoCTs, as well as the major challenges in the clinical environment. © 2023 Elsevier Ltd. All rights reserved

High prevalence of asymptomatic SARS-CoV-2 infection in a cohort of liver transplant recipients in central Italy

Asymptomatic subjects account for 25 to 45% of SARS-CoV-2 infections, and in particular, subjects on mild immunosuppressive therapy may have symptoms masked and could spread virus for an extended period of time. To determine the cumulative incidence of symptomatic and asymptomatic SARS-CoV-2 infections and associated risk factors, we conducted a prospective clinical and serological survey in a cohort of 278 liver transplant recipients (LTRs) from Central Italy. Three different serology tests were performed every 4 months in 259 LTRs between April 2020 and April 2021: one based on raw extract of whole SARS-CoV-2 virus and two on specific viral antigens (nucleoprotein and receptor binding domain) to detect specific IgG, IgM and IgA. Hundred fifteen LTRs who reported symptoms or close contact with a SARS-CoV-2-positive subject, or had a positive serological result underwent molecular testing by standard screening procedures (RT-PCR on naso-pharyngeal swab). Thirty-one past or active SARS-CoV-2 infections were identified: 14 had positive molecular test (64% symptomatic), and 17 had positive serology only (18% symptomatic). SARS-CoV-2 infection was not statistically related to gender, age, obesity, diabetes, renal impairment, type of anti-rejection therapy or time from transplant. Asymptomatic SARS-CoV-2 cases (61.3%) were more frequent in males and in those with glomerular filtrate rate >50 ml/min. Overall, the addition of repeated serology to standard diagnostic molecular protocols increased detection of SARS-CoV-2 infection from 5.1% to 10.9%. Anti-SARS-CoV-2 seroprevalence among our LTRs (11.2%) is comparable to the general population of Central Italy, considered a medium-impact area. Only one asymptomatic subject (6%) was found to carry SARS-CoV-2 in respiratory tract at the time of serological diagnosis.Copyright © 2021 The Authors

Impact of in-hospital medical management for COVID-19 pandemic on door-to-balloon time in patients with ST-elevation myocardial infarction

Background: Delayed door-to-balloon (DTB) time and deterioration of inhospital mortality during the coronavirus disease 2019 (COVID-19) pandemic have been reported. Little is known about the impact of changes in in-hospital medical management before primary percutaneous coronary intervention (PCI) for COVID-19 such as screening test (antigen or polymerase chain reaction (PCR) tests, chest CT for excluding the pneumoniae) and primary PCI under full personal protective equipment (PPE) on DTB time and in-hospital mortality. Purpose(s): The purpose of this study was to evaluate the impact of inhospital medical management for COVID-19 on DTB time and in-hospital mortality during COVID-19 pandemic period. Method(s): We compared DTB time and in-hospital mortality of 502 STelevation myocardial infarction (STEMI) patients during COVID-19 pandemic (February 2020 and January 2021) with 2035 STEMI patients before pandemic (February 2016 and January 2020) using date from Mie ACS registry, a retrospective and multicenter registry. Result(s): The COVID-19 screening tests before primary PCI and/or primary PCI under full PPE was performed on 173/502 (34.5%) patients (antigen or PCR tests;39 (7.8%), chest CT;156 (31.3%), full PPE;11 (2.2%)). These patients had lower rate of achievement of DTB time <=90 min compared with others (Figure 1A). Moreover, In-hospital management of COVID-19 screening tests and/or primary PCI under full PPE was an independent factor of DTB time>90 min with odds ratio of 1.94 (95% confidential interval: 1.37-2.76, p<0.001). In addition, in-hospital mortality of those patients was higher compared with others (Figure 1B). Conclusion(s): In-hospital medical management for COVID-19 screening tests before primary PCI and/or primary PCI under full PPE was the independent factor of DTB time>90 min. This study reinforces the need to focus efforts on shortening DTB time, while controlling the epidemic of infection.

Can autofluorescence and fluorescence imaging be useful in fight with COVID-19 pandemia?

The entire medical world gathers information related to the COVID-19 pandemic, including its spread analysis, disease characteristics, morbidity and mortality statistics, as well as factors limiting and promoting infection and severe course, and above all potential treatment options. Scientific research is being carried out on a large scale on methods of early detection of COVID-19 infection, including imaging methods such as computed tomography or ultrasound imaging. The importance of imaging methods is increasingly emphasized in the literature as sensitive and specific, often with greater clinical utility than mass-applied serological tests. Especially in large urban agglomerations such as Silesia, the wide availability of these imaging methods as screening methods in the clinical assessment of potentially infectious patients seems to be important. The literature on the COVID-19 epidemic emphasizes the significant role of integrated diagnostic methods including basic science as well as radiological and endoscopic imaging methods in the diagnosis of COVID-19 infection and its possible complications. The study presents potential possibilities of using the phenomena of autofuorescence and fluorescence in supporting the diagnosis of patients with suspected COVID-19 infection. The study presents preliminary results of case studies of patients suspected of being infected with COVID-19, and shows the multidimensional application of fluorescent phenomena in supporting diagnostics. One of the main tools used in the study is autofluorescent bronchoscopy as a method that, in synchronization with high resolution tomography analysis, significantly facilitates obtaining representative material for RT-PCR. The study also showed the potential for assessing fluorescent material under fluorescence microscopy, which can significantly facilitate diagnostics in the future and speed up existing screening tests to complement genetic diagnostics.Copyright © 2023

Adjusted D-dimer to Exclude Concurrent Pulmonary Embolism in Patients with COVID-19

Objectives: To determine if elevated D-dimers in Severe Acute Respiratory Syndrome Coronavirus-2 (COVID-19) positive patients were predictive of concurrent pulmonary embolism (PE), and what, if any, adjusted D-dimer cutoff would be predictive of PE in COVID-19 patients. Background(s): COVID-19 has led to over 500,000 death the United States. COVID-19 has been linked to a prothrombotic state, increasing the affected individual's propensity to form blood clots which is reflected in elevated D-dimers levels. While elevated D-dimers have been associated with 28-day mortality (making them useful in tracking the disease), it is difficult, in the acute setting, to determine if an elevated D-dimer is due to COVID-19, a pulmonary embolism (PE), or both conditions simultaneously. Method(s): This was a retrospective chart review of emergency department patients who underwent a computed tomography pulmonary angiogram (CTPA) who had documented COVID-19 infections between March and December of 2020. Charts were ed for COVID-19 polymerase chain reaction (PCR) results, D-dimers levels, and CTPA results. Kruskal-Wallis rank sum one-way analysis of variance and sensitivity analyses were completed via the software R. Result(s): Of 346 COVID-19 positive patients by nasal swab PCR, 24 (6.9%) had a PE on CTPA. The average D-dimer in the subset was 22,768 ng/dL vs 3,620 ng/dL in COVID-19 positive but PE negative patients (p=.034). As a screening test for concurrent PE, a D-dimer cut off of 1,000ng/dL or, for those over 50, [age in years]*20 ng/dL, had a sensitivity of 96%, specificity of 48% and negative predictive value (NPV) of 99.4%. A cut off of 1,000ng/dL had a sensitivity of 100%, specificity of 44% and NPV of 100%. Conclusion(s): Emergency department patients with COVID-19 and a PE have a significantly higher elevation in their D-dimer when compared to COVID-19 positive patients without a PE. A flat cut off of 1000ng/dL or a two tiered cut off of 1,000ng/dL for those <50 years old and [age in years]*20 ng/dL for those >50 years old proved to be reasonable screening tests for concurrent PE in COVID-19 positive patients.Copyright © 2023

Development of a Novel in-Vitro Hcov-Oc43 Screening Method

Aim: To develop a simple, inexpensive antiviral screening assay, applicable to SARS-CoV-2, using a plate-based bioassay approach to assess the in-vitro activity of compounds against HCoV-OC43. Background(s): Despite the successful deployment of vaccines against SARS-CoV-2 there remains a need for effective antivirals for acute infection treatment. A distinct problem facing the search for new anti-coronavirus compounds is the cost of antiviral screening, compounded by the biosecurity concerns of live SARSCoV- 2 culture. In concert with low pathogenic surrogate virus use, the resazurin reduction assay, which is often employed for compound cytotoxicity assessments can be employed for safe, rapid and inexpensive antiviral screening. Method(s): In-vitro cell based resazurin reduction assays were optimised using remdesivir as a control compound for the assessment of anti-HCoV-OC43 activity. Following optimisation, 246 purified natural compounds from the University of Western Australia's compound collection,were screened using the resazurin bioassay as a primary screen, under pre-treatment and cotreatment conditions. Five compounds, which demonstrated anti- HCoV-OC43 activity, were chosen for secondary screening with dose responses determined using qRT-PCR. Result(s): Primary screens of the 246 compounds using the resazurin bioassay identified five compounds with a relative viral inhibition >60% and a relative cell viability >70% (Table 1). The Z factor of the pre-treatment and co-treatment assays was >0.5 (average +/- SD;0.85 +/- 0.07, 0.91 +/- 0.03 respectively). Further dose response analysis of the top five compounds identified one compound with an IC50 value <10 muM. Conclusion(s): The method developed is an appropriate primary screening tool for the identification of novel compounds with anti-HCoV-OC43 activity.Copyright © 2023 Southern Society for Clinical Investigation.

India's policy and programmatic response to mental health of young people: A narrative review

India's response to meet the mental health needs of 252 million young people between 15 and 24 years is guided by the Mental Healthcare Act 2017 (MHCA), which advocates a rights-based approach to receiving mental healthcare, the National Mental Health Policy 2014, and the National Mental Health Program operational since 1982. We undertook a comprehensive narrative review of policies, programs, and legislations across five ministries of the Government of India-Health and Family Welfare, Education, Women and Child Development, Youth Affairs and Sports, and Social Justice and Empowerment-over the last ten years to map their approach and identify enablers and barriers for promoting youth mental health in India. Our work builds on the previous reviews on children and adolescents' mental health in India and captures the rapidly advancing policy landscape amidst the new challenges and opportunities presented by the COVID-19 pandemic, especially the increasing acceptability of digital health interventions including tele-consultations. We note that all the five ministries recognized mental health as an important aspect of overall development and well-being of young people. However, their approach is fragmented and a comprehensive approach to youth mental health is missing in the Indian context. Having said that, many enablers for integration of preventive, promotive, and curative mental health interventions exist especially as mental health is increasingly being recognized as an integral part of the comprehensive primary healthcare. However, much needs to be done in terms of strategic planning for screening, early detection and treatment, and developing strong referral systems between community, schools and mental healthcare services. Effective implementation of MHCA, sustainable intersectoral integration of mental health across youth-oriented services, empowerment of young people, and judicious use of digital technology hold the key to reimagining the approach to advance young people's mental health in India.Copyright © 2022 The Authors

Epidemiology, risk factors, and prevention of colorectal cancer.

Background: Colorectal cancer remains the fourth most common malignancy in Korea, and has been ranked as the third leading cause of cancer deaths in 2020. This study aims to describe the epidemiologic status of colorectal cancer in Korea, and provide basic data for effective primary and secondary prevention methods by summarizing risk factors and screening tools. Current Concepts: Although colorectal cancer incidence and mortality have decreased in recent years in Korea, it still poses a significant public health burden. From the early 1990s until the mid-2000s, the 5-year relative survival of patients with colorectal cancer in Korea continuously increased. This can be attributed to the successful introduction of the government-led screening program;development of improved surgical techniques, anticancer drugs, and adjuvant treatment;and advances medical resources and infrastructure along with economic growth. However, since the late 2000s, the improvement in survival has stagnated. The coronavirus disease 2019 outbreak has reduced hospital visits and screenings, which is assumed to cause delays in diagnosis, leading to a worse prognosis in the patients. To overcome these obstacles, it is essential to explore modifiable environmental risk factors and appropriate screening test methods in Korea. Discussion and Conclusion(s): Primary prevention through risk factor modification and secondary prevention using suitable screening programs can reduce the incidence and mortality rates of colorectal cancer.Copyright © Korean Medical Association.

Impact of COVID-19 pandemic on oral and maxillofacial surgery in Japan: A report from a questionnaire survey during the different phases of the pandemic

COVID-19 pandemic has provided a new challenge to healthcare systems and medical care providers. In the current study, we describe the challenges faced and actions taken to provide optimum healthcare in Japan during the COVID-19 pandemic based on the results of a questionnaire survey that was conducted by oral and maxillofacial surgeons. A total of 24 Japanese institutions participated in the study. The first survey was conducted between June 22, 2020 and June 26, 2020, and the second survey was conducted between October 23, 2020 and November 8, 2020. The questionnaire focused on the practical situation in the respondent's hospital, personal protective equipment (PPE) availability, and what alterations had occurred compared to the situation before the COVID-19 pandemic. The commonest reported duration of restrictions to the outpatient clinic was 1-2 months. All of the institutions had lifted their restrictions on outpatient services by September 2020. Surgical procedures in the operating room were restricted in 74% of hospitals in the first wave of the pandemic;however, 88% lifted their restrictions and restarted their regular surgical services by November 2020. Although, non-urgent or elective procedures were delayed, surgeries for malignant tumors, maxillofacial infections, and trauma were performed at almost all hospitals during the pandemic. Health care institutions will require a new approach to maintain patient volume and recover from the pandemic. Going forward, it is also necessary to minimize the risk of exposure and transmission to health care personnel as well as patients.Copyright © 2021 The Authors

Perceptions, insights, and attitudes (P.I.A.) of selected filipino female physicians on cardiovascular risks and diseases

Introduction: In 2012, coronary heart disease and stroke are the leading causes of death worldwide, accounting for more than 31% of deaths from all causes. In 2020, PH statistics showed that ischemic heart diseases were the leading causes of death in the Philippines (PH), responsible for 17.3% of the total deaths. Objective(s): To determine the knowledge, perceptions, insights and attitudes on cardiovascular disease (CVD) prevention, personal health-related lifestyle practices, and lifestyle counseling practices of selected female physicians who are practicing or training in the PH through an online survey. Method(s): A descriptive ambispective cross-sectional study where the survey questionnaire of Ameh, et al. (2019) was modified with the authors' permission, was conducted online and answered by consenting female physicians. 484 participants' data were collated and analyzed. Result(s): Majority had accurate responses for the CVD prevention knowledge items (Figures 1 and 2). Among the participants, 36.98% had hypertension, 32% were obese, 28.5% had dyslipidemia, and 17.2% had diabetes mellitus. Sleep of 6-8 hours is practiced by 60.33%, 53.51% eat vegetables and fruits daily, 55.79% prefer fish and seafood, 89.05% do not smoke, 61.2% take coffee or black tea daily, 84.51% have no regular exercise, and 30.79% of those who do only exercise for 10-20 minutes. Moreover, 67.98% add salt, soy or fish sauce to their meals, and 72.73% do not drink enough water daily. In addition, 44.42% do not undergo annual general check-up and 58.06% do not have a personal physician. Limitations due to COVID-19 pandemic, lack of education, and expensive screening tests are perceived to be major barriers to CVD screening. More than 90% of our participants practice health teachings on diabetes mellitus prevention, high blood pressure screening, cholesterol screening and management, nutrition, and weight management. Counseling on regular exercise, smoking, and alcohol abuse are being practiced by 88.02%, 85.74%, and 83.88% of our respondents, respectively. Conclusion(s): There are female physicians who are not aware of the World Health Organization's recommendations on the prevention of CVD, who do not do health teaching and counseling, and who practice unhealthy lifestyle. Changing physicians' knowledge and behavior towards CVD prevention is a great challenge to improve standards of CVD prevention. Improvement and enhancement in education of both physicians and patients, together with more consultation time, financing for CVD prevention, and comprehensive, multidisciplinary preventive cardiology programs supported by government and societies in favor of prevention are some of the best ways to improve management of CVD risk factors and prevention.
