Reassures Me There Are People Around Who Care about Me: Analyzing Meanings of Support for People with Epilepsy

Aims The study aimed to examine the nature and outcomes of social support for the well-being and quality of life (QoL) of adults with epilepsy. Methods The Australian Epilepsy Longitudinal Survey's 5 th Wave included the Medical Outcomes Study Modified Social Support Survey on four dimensions of social support and the QOLIE-31. Both numerical data and open-ended responses were analyzed quantitatively and qualitatively. A mixed method was used where quantitative analysis used t -tests, analysis of variance and block recursive regression, and qualitative analysis identified themes. Results Three-hundred thirty-two people with epilepsy (PWE) participated. The quantitative component showed that for emotional/informational support being older and living alone were key factors. These as well as household income were important in tangible support. For affectionate support living alone and household income were factors, but only income was a factor for positive social interaction. In addition, only positive social interaction predicted increased QoL. In the qualitative component of the study both positive and negative supports were identified for the emotional/informational supports. Many reported the benefits of having information, although some reported failure to have their needs taken seriously by health professionals or epilepsy associations. Inability to drive was an important feature of negative tangible support as was finding some assistive services unaffordable. Reports of positive social interaction identified being accepted as a person with epilepsy that is the primary concern. Peer support plays a role here. Discussion The findings of factors affecting the four dimensions of support in this study have supported a number of studies. This includes the effects of positive social interaction on QoL. The qualitative analysis supports these results, but it also contributes to deeper understanding of support in the lives of PWE. Conclusion Social support is a particularly important issue for PWE. The results of this study demonstrate the complexities and benefits of obtaining the appropriate forms of support. This survey took place before the coronavirus disease 2019 pandemic and it may well be that this phenomenon affects PWE's support needs. Copyright © 2023. Indian Epilepsy Society.

Low- and mid-level equine assisted services improved mood and state anxiety levels in health-care workers

The aim of this study was to measure the effect of equine assisted services (EAS) on mood and anxiety in health-care workers. While the emotional toll of the COVID-19 pandemic has been felt in every aspect of our society, health-care workers have been hit especially hard. A survey conducted by Mental Health America during June - September in 2020, found 93% of health-care workers were experiencing stress and 86% reported experiencing anxiety. There is research to support a wide range of interventions to address stress, low mood, and anxiety, including pharmaceuticals, physical exercise, and animal interaction. While several studies have shown an improvement in anxiety and mood after interaction with horses, few studies have included a physically active control group to consider the effect of exercise on results. In this study conducted in October 2021, participants were recruited from area hospitals and randomly assigned to a control group (30-min guided walk with no horse interaction, n = 17), a low level EAS group (30-min self-guided farm tour, n = 20), or a mid-level EAS group (30 min of grooming a horse, n = 19). Before the intervention, participants completed a demographic survey. Pre and post activity, participants completed the Brief Mood Introspection Scale (BMIS) and State Anxiety Inventory for AdultsTM that measured currentfeelings of mood and anxiety, respectively. Data were analyzed using the repeated measures one-way ANOVA procedure in SPSS. This study was approved by the MSU Human Research and Protection Program and the Institutional Animal Care and Use Committee. Fifty-six health-care workers participated in the study, with 32% having worked in health care for less than 5 years and 33.9% having worked in health care for over 20 years. All participants had a significant improvement in State-Anxiety scores after completing their group activity (P < 0.001), with no differences among groups. Similarly, all groups had an improved BMIS score (P < 0.001). However, there was significantly greater improvement in BMIS scores in the mid-level EAS (P < 0.01) when compared with the control group. While all participants in this study improved both their current feelings of anxiety and mood after completing an activity on the farm, there was a greater improvement in mood in those individuals who spent 30 min grooming a horse when compared with the walk group without horse interaction. The results from this study provide further support for the impact of equine assisted services as a means of improving mood.Copyright © 2023

Interval Load Forecasting for Individual Households in the Presence of Electric Vehicle Charging

The transition to Electric Vehicles (EV) in place of traditional internal combustion engines is increasing societal demand for electricity. The ability to integrate the additional demand from EV charging into forecasting electricity demand is critical for maintaining the reliability of electricity generation and distribution. Load forecasting studies typically exclude households with home EV charging, focusing on offices, schools, and public charging stations. Moreover, they provide point forecasts which do not offer information about prediction uncertainty. Consequently, this paper proposes the Long Short-Term Memory Bayesian Neural Networks (LSTM-BNNs) for household load forecasting in presence of EV charging. The approach takes advantage of the LSTM model to capture the time dependencies and uses the dropout layer with Bayesian inference to generate prediction intervals. Results show that the proposed LSTM-BNNs achieve accuracy similar to point forecasts with the advantage of prediction intervals. Moreover, the impact of lockdowns related to the COVID-19 pandemic on the load forecasting model is examined, and the analysis shows that there is no major change in the model performance as, for the considered households, the randomness of the EV charging outweighs the change due to pandemic.

Patient Survey in Medical Practices on their Visit during the SARS-CoV-2 Pandemic.

Background: Since the beginning of the SARS-CoV2 pandemic medical practices have implemented diverse protective measures to contain the pandemic, practice organization and structures were adapted. In order to get information about patients' perception of their doctors' visit during the pandemic, we conducted a patient survey in medical practices. Method(s): Cross-sectional study of 58 patients, who were interviewed in four medical practices (family physicians and specialists) in the South West of Munich from 02.04.-17.04.2020 on the following topics: "personal risk assessment", "sense of security and perception of protection measures in the practice setting", "importance of the doctor's visit" and "change of medication, nicotine consumption". By means of a questionnaire with 24 items, data were collected anonymously. Results are presented descriptively and via ANOVA as well as via linear regression. Result(s): The personal risk assessments for COVID-19-disease and for a severe course of COVID-19 were rated low moderate, independent of sex or age. Around 8% of the surveyed patients discussed their personal risk with their doctors. The sense of security in the practice setting was rated high. The rating of the protection equipment was good as well, and closely met expectations. The personal importance of the visit varied. Only 6% had considered cancelling their visit beforehand. A change of medication due to SARS-CoV-2 pandemic was not observed. Conclusion(s): The patient survey provides a snapshot of the outpatient setting from the patient's perspective in a hyperdynamic pandemic situation. Yet, due to the small study population, the results have to be interpreted with caution.Copyright © 2021, Deutscher Arzteverlag.

Pancreatic Stone Protein (PSP) as a predictive biomarker of multiple organ failure and clinical outcome

Background: COVID-19 syndrome is associated with high morbidity and mortality in haemodialyzed patients. Pancreatic Stone Protein (PSP) is an early biomarker of sepsis and a prognostic biomarker of disease severity in critically-ill patients and can be rapidly measured at the patient's bedside with a point-of-care-test from a small drop of whole blood. The aim of our pilot was to investigate PSP in patients requiring haemodialysis with SARS-CoV-2 infection, at different severities of COVID-19 disease. Method(s): Between February and July 2021, 23 patients (6 severe COVID-19 with Acute Kidney Injury, 6 moderate COVID-19 haemodialyzed, 2 haemodialyzed without COVID-19 and 3 healthy controls) were recruited at the University Hospital of Foggia for PSP evaluation. Biomarker's measurements were performed within 48 hours after admission or upon arrival for haemodialysis (pre-treatment). PSP was measured at the patient's bedside with "abioSCOPE", a point-of-care test capable of evaluating PSP levels in five minutes from a small drop (50mul) of whole blood or serum. Result(s): The preliminary results of this pilot study showed a trend for PSP to increase along with the severity of disease. In fact, serum PSP levels were significantly higher in Intensive Care Unit subjects than in COVID-19 negative haemodialysis subjects and controls (ANOVA p=0.032). Furthermore, PSP levels were significantly higher in subjects who died (p<0.017). Whether this increase is due to the kidney injury or COVID-19 disease remains unknown, and more research is needed to understand the relationship. Conclusion(s): Several clinical studies published in literature have shown the predictive value of PSP in the early identification of sepsis and severity of the clinical outcome. In our experience we have seen a trend for PSP to increase with disease severity also in COVID-19 patients. These results are preliminary, but PSP was significantly higher in patients who died, in accordance with the literature. This experience also has demonstrated the feasibility of a point of care system to be easily implemented in the unit and adopted by personnel and its design enables fast results and immediate decisions to be taken, especially in urgent situations.

CD4+ T cells from preeclamptic patients cause hypertension, autoantibodies and cognitive dysfunction in a pregnant rat model

CD4+ T Cells from Preeclamptic patients with or without a history of COVID-19 during pregnancy cause hypertension, autoantibodies and cognitive dysfunction in a pregnant rat model Objective: Preeclampsia (PE) new onset hypertension (HTN) during pregnancy, is associated with increased autoantibodies, cerebral blood flow (CBF) impaired cognitive function and memory loss. We have shown adoptive transfer of placentalCD4+T cells from PE women into athymic nude pregnant rats causesHTNand autoantibodies associated with PE.COVID-19 (CV) during pregnancy is associated with increased diagnosis of PE. However, we do not know the role of CD4+ T cells stimulated in response to CV in contributing to the PE phenotype seen patients with a Hx of CV during pregnancy. Therefore, we hypothesize that adoptive transfer of placental CD4+ T cells from patients with a CV History (Hx) during pregnancy with PE causes HTN, increased CBF and cognitive dysfunction in pregnant athymic nude recipient rats. Study Design: Placental CD4+ T cells isolated from normotensive (NP), PE, Hx of CV normotensive (CV Hx NT), and Hx of CV with PE (CV Hx+PE) at delivery. One million CD4+ T cells were injected i.p. into nude athymic rats on gestational day (GD) 12. The Barnes maze and the novel object recognition behavioral assays were used to assess cognitive function on GDs 15-19. Blood pressure (MAP) and CBF were measured by carotid catheter and laser Doppler flowmetry on GD19, respectively. A two-way ANOVA was used for statistical analysis. Result(s):MAPincreased inCVHx+PE (111 +/- 4, n = 4) and PE recipient rats (115 +/- 2 mmHg, n = 5) compared to CV Hx NT (100 +/- 4, n = 5) and NP (99 +/- 3 mmHg, n = 4, P < .05). CV Hx+PE and PE exhibited latency with errors navigating in the Barnes maze compared to CV Hx NT and NP groups. Locomotor activity was decreased in CV Hx+PE (P < .05) compared to PE, CV Hx NT, and NP groups. CV Hx+PE and PE spent more time exploring identical objects compared to CV Hx NT and NP groups. PE and CV Hx+ PE had increased CBF compared to CV Hx NT and NP rats. Conclusion(s): Our findings indicate that pregnant recipients of CD4+ T cells from PE with or without a Hx CV during pregnancy cause HTN, increased CBF and cognitive dysfunction compared to recipients of NP or NT Hx COVID-19 CD4+ T cells.

SARS-CoV-2 infection disrupts trophoblast function and placental syncytial barrier integrity via its accessory protein, ORF3a

Problem: Although it is rare for a SARS-CoV-2 infection to transmit vertically to the fetus during pregnancy, there is a significantly increased risk of adverse pregnancy outcomes due to maternalCOVID- 19. However, there is a poor understanding of such risks because mechanistic studies on how SARS-CoV-2 infection disrupts placental homeostasis are significantly lacking. The SARS-CoV-2 proteome includes multiple structural and non-structural proteins, including the non-structural accessory proteinORF3a. The roles of these proteins in mediating placental infection remain undefined. We and others have shown that autophagy activity in placental syncytium is essential for barrier function and integrity. Here, we have used clinical samples and cultured trophoblast cells to evaluate syncytial integrity of placenta exposed to SARS-CoV-2. The objective of our study was to investigate potential mechanisms through which SARS-CoV-2 impairs placental homeostasis and causes adverse pregnancy outcomes. We tested the central hypothesis that an essential SARS-CoV-2 non-structural and accessory protein, ORF3a, uniquely (amongst multiple viral proteins tested) with a novel three-dimensional structure andwith no homology to any other proteins is a key modulator of placental trophoblast cell dynamics via autophagy and intracellular trafficking of a tight junction protein (TJP), ZO-1. Method(s): We used clinical samples and cultured trophoblast cells to evaluate syncytial integrity of placentas exposed to SARS-CoV- 2. Autophagic flux was measured in placental villous biopsies from SARS-CoV-2-exposed and unexposed pregnant women by quantifying the expression of autophagy markers, LC3 and P62. Trophoblast cells (JEG-3, Forskolin-treated JEG-3, HTR8/SVneo, or primary human trophoblasts (PHTs)) were transfected with expression plasmids encoding SARS-CoV-2 proteins including ORF3a. Using western blotting, multi-label immunofluorescence, and confocal imaging, we analyzed the effect of ORF3a on the autophagy, differentiation, invasion, and intracellular trafficking of ZO-1 in trophoblasts. Using coimmunoprecipitation assays, we tested ORF3a interactions with host proteins. t-tests and one-way analyses of variance (ANOVAs) with post hoc tests were used to assess the data, with significance set at P < .05. Result(s): We discovered :1) increased activation of autophagy, but incomplete processing of autophagosome-lysosomal degradation;2) accumulation of protein aggregates in placentas exposed to SARS-CoV- 2. Mechanistically, we showed that the SARS-CoV-2 ORF3a protein, uniquely 3) blocks the autophagy-lysosomal degradation process;4) inhibits maturation of cytotrophoblasts into syncytiotrophoblasts (STBs);5) reduces production ofHCG-beta, a key pregnancy hormone that is also essential for STB maturation;and 6) inhibits trophoblast invasive capacity. Furthermore, ORF3a harbors an intrinsically disordered C-terminus withPDZ-bindingmotifs.We show for the first time that, 7) ORF3a binds to and co-localizes with the PDZ domain of ZO-1, a junctional protein that is essential for STB maturation and the integrity of the placental barrier. Conclusion(s): Our work outlines a new molecular and cellular mechanism involving the SARS-CoV-2 accessory protein ORF3a that may drive the virus's ability to infect the placenta and damage placental syncytial integrity. This implies that the mechanisms facilitating viral maturation, such as the interaction of ORF3a with host factors, can be investigated for additional functionality and even targeted for developing new intervention strategies for treatment or prevention of SARS-CoV-2 infection at the maternal-fetal interface.

Different Moments Create Different Spillovers: A Study of Commodity Markets

Although the spillover effects of return and volatility risk across commodity markets have been demonstrated, evidence of extreme risk spillovers is limited. Using an autoregressive conditional density model, this study estimates the conditional skewness of nine S&P Goldman Sachs Commodity indices and then applies the Diebold-Yilmaz TVP-VAR-based approach to investigate the higher moment spillovers across commodity markets. Our findings provide evidence of extreme risk transfers from one commodity index to another. Among three energy indices including crude oil, natural gas and gasoil, crude oil transmits the most return, volatility risk and extreme risk to the agricultural indices and precious metal indices. Furthermore, our results confirm that spillovers in all three moments were significantly strengthened by extreme events such as the September 11 attacks, the global financial crisis, the food price crisis, the violent shock of international oil prices and the coronavirus disease of 2019. However, different events may have different impacts on spillovers. Finally, the results indicate that return spillover and skewness are affected by extreme events with almost the same intensity and direction for most periods.

Coagulation Parameters Changes Associated with Covid-19 Vaccination

A global spreading corona virus at 2019 (COVID-19) declared as emergent worldwide, due to its quick spreading and high rates of mortality that serious disruptions. The objective of this research is to explore further into effect of different types of covid-19 vaccinations (Pfizer, AstraZeneca and Sinopharm) on some coagulation parameters from random samples of students in college of pharmacy/ university of Ker-bala. A case-control study was carried out with Iraqis living in Kerbala city particularly college students in Kerbala University/ College of Pharmacy from 2021/1/16 to 2022/4/16. This study was done to encompass quantitative and qualitative analysis of covid 19 vaccination types and possible thrombosis that occur after vaccination. The enrolled sixty participants of male and female were aged 18years and above. A questionnaire was made questions pertaining age were inquired to make sure participants fulfilled the criteria for in-clusion, past medical history, previous infection with covid 19 were incorporated into the survey. The scien-tific and ethical committee provided their ethical approval in college of pharmacy at University of Kerbala. Our results in this study indicate significant differences in coagulation parameters readings of (Pt, Ptt) between vaccination groups and control by using ANOVA statistical analysis of SPSS. Our study showed that the difference between the vaccinated and unvaccinated groups was considerable (Pfizer, AstraZeneca & Sinopharm Covid 19 vaccines) and control group in thrombotic measurements time and platelet mean value. The most effective and economical method of preventing COVID-19 infection is still vaccination. A number of COVID-19 vaccines have been developed quickly, but more research needs to be done on any side effects that may appear.Copyright © 2023, Colegio de Farmaceuticos de la Provincia de Buenos Aires.

The impact of transgender minority stress and emotion regulation on suicidality and self-harm

Transgender and gender diverse (TGD) individuals experience high levels of minority stress, as well as a high prevalence of suicidality and self-harm. The current study investigates if emotion regulation mediates the relationships of minority stressors with self-harm and suicidality. TGD adult primary care patients (N = 115) completed a survey including measures of minority stressors, emotion dysregulation, self-harm, and suicidality. Emotion regulation mediated the relationship between victimisation and suicidality. Emotion regulation did not mediate the relationship between victimisation and self-harm. TGD individuals' suicide risk may be increased when they experience victimisation through increased emotion dysregulation.

Burnout syndrome and remote learning strategies during the pandemic of COVID-19: a longitudinal study of Agrarian Sciences students

Purpose:We aimed to evaluate the levels of Burnout Syndrome (BS) in Agricultural Sciences students, both before and during the COVID-19 pandemic period.Design/methodology/approach:We accessed 77 students for Burnout Syndrome using the Maslach Burnout Inventory-Student Survey (MBI-SS) on two occasions, the first in February and the second in October 2020. Sixty-three students completed both phases. The data were analyzed in a mixed factorial scheme (Three-way ANOVA;p < 0.05).Findings:Academic efficacy improved over time without interference of sex or physical activity frequency (p < 0.001). The emotional exhaustion domain significantly reduced over time in women who declared to practice physical activity (p = 0.037). A similar effect was observed in both men and women for the cynicism domain (p < 0.001). Online teaching strategies and the regular practice of exercise were associated to reduced levels of BS during the pandemic.Practical implications:The adoption of the emergency remote education system (ERE) associated with the practice of exercise can mitigate the harmful effects of the COVID-19 quarantine on the mental health of students.Theoretical implications:The ERE can be an effective strategy to mitigate BS levels in Agricultural Science students in the post-pandemic period.Originality/Value:This is the first study that presents results of BS in students of Agricultural Sciences, comparing before and during the COVID-19 pandemic.

Effects of COVID-19 on passenger shipping activities and emissions: empirical analysis of passenger ships in Danish waters

This paper focuses on the analysis of the COVID-19 effects on passenger shipping in Danish waters as an example and aims to analyse the differences in passenger vessel activities and emissions before and after the COVID-19 outbreak. Two sets of Automatic Identification System (AIS) data for the passenger ships sailing in Danish waters associated with the whole year respectively for 2020 and 2019 are used for a comprehensive evaluation of the passenger shipping activities in the region by means of the analysis of variance and bottom-up emission models. A comparison of those results based on the two datasets shows that the COVID-19 pandemic has a major impact on cruise ships, with a significant reduction in the number of ships, average speed, and average draught. In contrast, the pandemic has a smaller impact on ferry-pax only and ferry-ro pax vessels. The effects can also be seen from the fact that, after the COVID-19 outbreak, SOx emissions from cruise ships, ferry-pax only and ferry-ro pax vessels were reduced by 50.71%, 0.51% and 0.82%, respectively. This investigation provides an important reference for policy makers in the marine environment sector.

The Impact of the COVID-19 Pandemic on Financial Condition and Mortality in Polish Regions

The study aimed to assess the impact of the COVID-19 pandemic on the financial condition and mortality in Polish voivodeships. To achieve this objective, the relationship between the number of deaths before and during the pandemic and the financial condition of the provinces in Poland was studied. The study covered the years 2017–2020, for which a one-way ANOVA was used to verify whether there was a relationship between the level of a province's financial condition and the number of deaths. The results of the study are surprising and show that before the COVID-19 pandemic, there was a higher number of deaths in provinces that were better off financially, but the relationship was not statistically significant. In contrast, during the pandemic, a statistically significant strong negative correlation between these values was proven, which, in practice, shows that regions with better financial conditions had a higher number of deaths during COVID-19.

Different reversibility of skeletal muscle mass and strength in elderly Japanese women after the first wave of COVID-19

BackgroundRestrictions on outdoor movements due to the coronavirus disease (COVID-19) pandemic have led to a decreased physical activity;this can lead to sarcopenia and frailty in older adults. Our recent study has demonstrated a significant decrease in the trunk muscle mass immediately after the pandemic's first wave (April–May 2020) among Japanese community-dwelling older women. In the present study, we further examined whether muscle mass recovery or deterioration occurs after 1 year of the pandemic's first wave by comparing physical measurements among the following assessment periods: before the first wave, immediately after the first wave, and at 1-year follow-up thereafter.MethodsThis study included 77 women (78.0 ± 5.7 years) who underwent physical measurements for muscle mass, grip strength, one-leg stand-up ability (3 s), and oral motor skills and answered questionnaires on sociality (social network, participation, and support) in the three assessment periods.ResultsThe frequency of going out and the subjective vitality were significantly decreased immediately after the first wave;these recovered at the 1-year follow-up (P < 0.001). When comparing muscular measures, the trunk muscle mass index preferentially decreased immediately after the first wave but recovered significantly at the 1-year follow-up (P < 0.001). Conversely, the appendicular skeletal muscle mass index (ASMI) and grip strength continued to decrease until the 1-year follow-up (P < 0.001 and P = 0.03, respectively). The ability to perform a one-leg stand-up for 3 s and the oral motor skills did not change significantly across the assessment periods. The prevalence of pre-sarcopenia and sarcopenia tended to increase during these periods (P = 0.068). The reduction and subsequent recovery patterns for sociality were similar to those observed for the trunk muscle mass.ConclusionsOur findings demonstrated differences in the reversibility of skeletal muscle mass and strength at 1 year after the first wave of the COVID-19 pandemic: the trunk muscle mass declined acutely and recovered rapidly, whereas the ASMI and grip strength declined continuously. These differences in the skeletal muscle recovery and deterioration might help formulate short-term or long-term strategies for COVID-19-related sarcopenia prevention in community-dwelling older adults.

Identification of Facebook posts on nephrology-related terms that benefit patient outreach

Objective: The impact of social media on public health has been examined in various studies. However, none have explored user engagement based on the type of Facebook posts related to renal disease. Therefore, the present study sought to determine which type of nephrology-related posts have greater user engagement. Setting(s): Facebook pages. Method(s): The posts on a specific Facebook page curated by a team of nephrologists in Malaysia were examined in this cross-sectional study. The type of post, likes, comments, shares of a post and reach of a post were used for data analysis. Analysis of variance was used to quantify the relative contribution of each independent variable to the odds of the post being highly liked or shared. The Kruskal-Wallis test was used to compare links, photos, shared videos, status and videos for parameters such as reach, the number of times a specific piece of content has been displayed on a screen (impressions), and user engagement. Result(s): Shared videos and photos received the highest median reach of 5,862 and 5,880, respectively. People who 'liked' the page in 2019, 2020 and 2021 numbered 193, 4,196 and 2,835, respectively. Among the types of content on the Facebook page, photos and shared videos received the highest median lifetime reach of the post compared to links, status and videos in terms of 'people who liked the page'. Conclusion(s): The study findings suggest that posting a video or photo maximises the chance of engagement and meaningfully impacts public health outcomes.Copyright © The Author(s) 2023.

General Surgery Resident Case Numbers During the Covid-19 Pandemic

Introduction: The COVID-19 pandemic has had widespread effects on the healthcare system. For trainees, one particular detriment has been the cancellation of elective operations, reducing clinical experience and procedural volumes. Measures instituted to combat the pandemic have resulted in decreased cancellation of elective cases to varying degrees. The aim of this study is to evaluate the ongoing effect of the pandemic on resident operative volume. Method(s): Operative case numbers of general surgical graduates in 2019, 2020, and 2021 were extracted from the Accreditation Council for Graduate Medical Education case logs. Data included mean total cases/graduate and means for individual case types. Data was considered by overall number of cases and cases performed as surgeon chief. Analysis of variance was employed to compare groups with p<0.05 considered significant. Result(s): Mean total major cases differed significantly among groups with reduced volume noted for 2020 graduates but no difference in volume between 2019 and 2021 graduates (1070.5+/-150 vs 1054.8+/-155 vs 1074.1+/-164, p=0.0041). This same pattern was noted for surgeon chief total cases (288.6+/-69 vs 264.4+/-67 vs 286.2+/-73, p<0.0001) as well as several major general surgery subcategories including cases involving the stomach, small intestine, large intestine, biliary system, among others. Conclusion(s): Despite continued reduction in and alteration of elective surgery practice, improved pandemic measures have allowed for increased surgical volume. This has translated to increased operative experience for graduating surgical trainees that are comparable to case numbers that preceded the pandemic. Ramifications for the 2020 graduating cohort as well subsequent cohorts require continued evaluation.

Seasonal Variation Analysis for Weekly Cases, Deaths, and Hospitalizations of COVID-19 in the United States.

Knowing the seasonality of COVID-19 helps decision-makers to take suitable interventions against the pandemic. In this study, we performed the Brown-Forsythe variance analysis on seasonal variations on different indicators based on the data on COVID-19 for the United States provided publicly by WHO. Our study finds that the seasonality of weekly cases and deaths of COVID-19 are strongly statistically supported by the data. The weekly total cases(/deaths) in winter are three to seven times(/two to three times) more than the other three single seasons. The ICU patients in winter and autumn are four to five times more than spring. The weekly hospital admissions in winter are four times more than spring. The mean of the positive rate in winter is five times more than spring. The findings of this research can be a reference in decision-making when taking interventions against the pandemic, such as taking stricter interventions in winter while considering less strict interventions in summer, etc.

L-Moments and calibration-based variance estimators under double stratified random sampling scheme: Application of Covid-19 pandemic

Extreme events gives rise to outrageous results in terms of population-related parameters and their estimates are usually done using traditional moments. Traditional moments are usually affected by extreme observations. This study aims to propose some new calibration estimators considering the L-Moments scheme for variance, which is one of the most important population parameters. a number of suitable calibration constraints under double stratified random sampling were defined for these estimators. The proposed estimators, which were based on L-Moments, were relatively more robust despite extreme values. The empirical efficiency of the proposed estimators was also assessed through simulation. Covid-19 pandemic data from January 22, 2020 to August 23, 2020 was taken into account in the simulation study. (c) 2023 Sharif University of Technology. All rights reserved.

Clinical Characteristics of Sars-Cov-2 Infection in Patients with Systemic Lupus Erythematosus in Argentina: Data from the Sar-Covid National Registry

Objectives: Patients with systemic lupus erythematosus (SLE) present greater severity of SARS-CoV-2 infection compared to the general population, particularly those with glomerulonephritis and who are treated with glucocorticoids. Likewise, high disease activity and some immunosuppressants have been associated with worse outcomes. The aim of this study was to describe the characteristics of SARS-CoV-2 infection in patients with SLE in Argentina from the SAR-COVID registry and to establish factors associated with a worse outcome. Method(s): Observational study. Patients diagnosed with SLE with confirmed SARS-CoV-2 infection (RT-PCR and/or positive serology) from the SAR-COVID registry were included. Data were collected from August 2020 to March 2022. The outcome of the infection was measured using the World Health Organization-ordinal scale (WHO-OS). Severe COVID-19 was defined as an WHO-OS value >=5. Descriptive analysis, Student's t , Mann Whitney U, ANOVA, Chi2 and Fisher's tests. Multivariable logistic regression. Result(s): A total of 399 patients were included, 93%female, with a mean age of 40.9 years (SD 12.2), 39.6% had at least one comorbidity. At the time of infection, 54.9% were receiving glucocorticoids, 30.8% immunosuppressants, and 3.3% biological agents. SARS-CoV-2 infection was mild in most cases, while 4.6% had a severe course and/or died. The latter had comorbidities, used glucocorticoids, and had antiphospholipid syndrome (APS) more frequently and higher disease activity at the time of infection. In the multivariate analysis, high blood pressure (OR 5.1, 95% CI 1.8-15.0), the diagnosis of APS (4.7, 95% CI 1.2-15.8), and the use of glucocorticoids (10 mg/day or more: OR 5.5, 95% CI 1.6-20.5) were associated with severe hospitalization and/or death from COVID-19 (WHO-EO >= 5). Conclusion(s): In this cohort of SLE patients with confirmed SARS-CoV-2 infection, most had a symptomatic course, 22.1% were hospitalized, and 5% required mechanical ventilation. Mortality was close to 3%. The diagnosis of APS, having high blood pressure, and the use of glucocorticoids were significantly associated with severe COVID-19.
