Risk Factors For Severe Symptoms Research Articles

Changes in mental distress among employees during the three years of the COVID-19 pandemic in Germany.

The COVID-19 pandemic changed the future of work sustainably and led to a general increase in mental stress. A study conducted during the second and third pandemic wave with a retrospective survey of the first wave among 1,545 non-healthcare workers confirmed an increase in anxiety and depression symptoms and showed a correlation with the occupational SARS-CoV-2 infection risk. This online follow-up survey aims to examine changes in mental distress as the pandemic progressed in Germany and to identify factors influencing potential changes. Longitudinal data from 260 subjects were available for this analysis. Mental distress related to anxiety and depression symptoms, assessed by the Patient Health Questionnaire-4 (PHQ-4), and occupational risk factors were solicited at the end of 2022 and retrospectively at the fifth wave. Categorized PHQ-4 scores were modelled with mixed ordinal regression models and presented with odds ratios (OR) and 95% confidence intervals (95% CI). A previous diagnosis of a depressive or anxiety disorder was a strong risk factor for severe symptoms (OR 3.49, 95% CI 1.71-7.11). The impact of occupational SARS-CoV-2 infection risk on mental distress was increased, albeit failing to reach the formal level of statistical significance (high risk OR 1.83, 95% CI 0.59-5.63; probable risk OR 1.72, 95% CI 0.93-3.15). Mental distress was more pronounced in those with a previous diagnosis of anxiety and depression. Confirmed occupational risk factors were protective measures against occupational SARS-CoV-2 infection perceived as inadequate, chronic work-related stress, overcommitment, reduced interactions with fellow-workers, and work-privacy conflicts. The pandemic had a negative impact on anxiety and depression symptoms among the studied non-healthcare workers, particularly early in the pandemic, although this effect does not appear to be permanent. There are modifiable risk factors that can protect workers' mental health, including strengthening social interactions among employees and reducing work-privacy conflicts.

Epigenetic age acceleration in surviving versus deceased COVID-19 patients with acute respiratory distress syndrome following hospitalization

BackgroundAging has been reported as a major risk factor for severe symptoms and higher mortality rates in COVID-19 patients. Molecular hallmarks such as epigenetic alterations and telomere attenuation reflect the biological process of aging. Epigenetic clocks have been shown to be valuable tools for measuring biological age in various tissues and samples. As such, these epigenetic clocks can determine accelerated biological aging and time-to-mortality across various tissues. Previous reports have shown accelerated biological aging and telomere attrition acceleration following SARS-CoV-2 infection. However, the effect of accelerated epigenetic aging on outcome (death/recovery) in COVID-19 patients with acute respiratory distress syndrome (ARDS) has not been well investigated.ResultsIn this study, we measured DNA methylation age and telomere attrition in 87 severe COVID-19 cases with ARDS under mechanical ventilation. Furthermore, we compared dynamic changes in epigenetic aging across multiple time points until recovery or death. Epigenetic age was measured using the Horvath, Hannum, DNAm skin and blood, GrimAge, and PhenoAge clocks, whereas telomere length was calculated using the surrogate marker DNAmTL. Our analysis revealed significant accelerated epigenetic aging but no telomere attrition acceleration in severe COVID-19 cases. In addition, we observed epigenetic age deceleration at inclusion versus end of follow-up in recovered but not in deceased COVID-19 cases using certain clocks. When comparing dynamic changes in epigenetic age acceleration (EAA), we detected higher EAA using both the Horvath and PhenoAge clocks in deceased versus recovered patients. The DNAmTL measurements revealed telomere attrition acceleration in deceased COVID-19 patients between inclusion and end of follow-up and a significant change in dynamic telomere attrition acceleration when comparing patients who recovered versus those who died.ConclusionsEAA and telomere attrition acceleration were associated with treatment outcomes in hospitalized COVID-19 patients with ARDS. A better understanding of the long-term effects of EAA in COVID-19 patients and how they might contribute to long COVID symptoms in recovered individuals is urgently needed.

The relationship between COVID-19, depressive disorder, and anxiety: a bidirectional Mendelian randomization study.

Previous clinical studies have found that negative mental states such as depression and anxiety are closely related to COVID-19 infection. We used Mendelian randomization (MR) to explore the relationship between depression, anxiety, and COVID-19 infection. Our data were based on publicly available GWAS databases. The COVID-19 samples were obtained from the COVID-19 Host Genetics Initiative (HGI). The depression samples were obtained from the Psychiatric Genomics Consortium (PGC). The anxiety samples were derived from the Finngen database. We used inverse-variance weighting (IVW) as the primary analysis method, with weighted median, MR Egger, and multivariate MRI adjustment. There was no causal effect of different COVID-19 infection statuses on depression and anxiety as determined by MR analysis. In addition, in the reverse MR analysis, we found a significant causal effect of anxiety on severe symptoms after COVID-19 infection. The results of the MR Egger regression, weighted median, and weighted mode methods were consistent with the IVW method. Based on sensitivity analyses, horizontal pleiotropy was unlikely to influence the final results. Our findings indicate that anxiety is a risk factor for severe symptoms following COVID-19 infection. However, the mechanism of interaction between the two needs further investigation.

Media coverage of COVID-19 health information in India: a content analysis.

SummaryEffective response to the COVID-19 pandemic is dependent on individual understanding of the disease and compliance to prevention measures. Early media depiction of health information about COVID-19 may influence public perceptions and behaviour. Media should ensure coverage is relevant, timely and actionable to encourage individuals to respond appropriately. India has been particularly affected by a large COVID-19 caseload. We analysed online reporting in India to assess how well the media represented health information about COVID-19 as per the World Health Organization’s Strategic Risk Communications guidelines. This included media coverage of symptoms, transmission and prevention. We found that limited articles (18.8%) provided actionable suggestions to readers, including urging people to stay at home and social distance. Most articles were relevant as per WHO COVID-19 updates, accurately covering symptoms, risk factors for severe symptoms, transmission and prevention. However, 40% of media coverage of treatments options provided misleading information, such as suggesting plasma therapy or chloroquine, were effective. In addition, only 1.9% of articles included discussion of equity issues, where many prevention activities such as distancing are less applicable in lower-income households. Sixty-seven per cent of articles quoting sources of information quoted credible sources such as public health agencies and researchers. Media coverage also did not appear to reflect WHO updates in a timely manner, with most of the coverage preceding these updates. The findings show that Indian media should focus on actionable and relevant reporting that provides guidance for individual response. Media should also endeavour to report on evidence-based prevention and treatment options to avert the spread of misinformation.

Structural racism and risk of SARS-CoV-2 in pregnancy.

BackgroundStructural racism leads to adverse health outcomes, as highlighted by inequities in COVID-19 infections. We characterized Black/White disparities among pregnant women with SARS-CoV-2 in Cuyahoga County which has some of the most extreme health disparities in the U.S., such as a rate of Black infant mortality that is three times that of White counterparts.MethodsThis was a retrospective cohort study using data collected as part of public health surveillance between March 16, 2020 until October 1, 2020. This study aimed to compare Black and Non-Black pregnant women infected with SARS-CoV-2 to understand how the distribution of risk factors may differ by race. Outcomes included age, gestational age at infection, medical co-morbidities, exposure history, socio-economic status, occupation, symptom severity and pregnancy complications.FindingsOne hundred and sixty-two women were included. 81 (50%) were Black, 67 (41%) White, 9 (0·05%) Hispanic, 2 (0·01%) Asian; and three did not self-identify with any particular race. More than half who supplied occupational information (n = 132) were essential workers as classified by the CDC definition (55%, n = 73). Black women were younger (p = 0·0062) and more likely to identify an occupational contact as exposing them to SARS-CoV-2 (p = 0·020). Non-Black women were more likely to work from home (p = 0·018) and indicate a personal or household contact as their exposure (p = 0·020). Occupation was a risk factor for severe symptoms (aOR 4·487, p = 0·037). Most Black women lived in areas with median income <$39,000 and Black women were more likely to have a preterm delivery (22·2% versus 0%, p = 0·026).InterpretationMany pregnant women infected by SARS-CoV-2 are essential workers. Black women are more likely than White counterparts to have occupational exposure as the presumed source for their infection. Limitations in occupational options and controlling risk in these positions could be related to lower socio-economic status, resulting from a long history of structural racism in Cuyahoga County as evidenced by redlining and other policies limiting opportunities for people of color.Fundingnone.

Predictive effect of cervical spinal cord compression and corresponding segmental paravertebral muscle degeneration on the severity of symptoms in patients with cervical spondylotic myelopathy

Previous studies have found that cervical sagittal parameters and spinal cord compression are important risk factors for cervical spondylotic myelopathy (CSM). An increasing number of scholars believe that cervical muscle condition is also one of the factors affecting the severity of symptoms in affected patients. To determine whether: the degree of corresponding segmental paravertebral muscle degeneration is related to the severity of symptoms in patients with CSM; the degree of cervical spinal cord compression can predict the severity of symptoms in patients with CSM. A retrospective study. From January 2015 to January 2019, 121 patients with CSM were enrolled. The visual analog scale (VAS), neck disability index (NDI) and modified Japanese Orthopedic Association (mJOA) were used to assess cervical spinal function and quality of life. From January 2015 to January 2019, 121 patients with CSM were enrolled. The inclusion criterion was the presence of complete cervical lateral radiography and magnetic resonance imaging (MRI) data. The following radiographic parameters were measured: (1) C0-C2 Cobb angle; (2) C2-C7 Cobb angle (CL); (3) T1 slope (T1S); (4) neck tilt (NT); (5) C2-C7 sagittal vertical axis (SVA); and (6) T1S-CL. The following MRI parameters were measured: (1) up(low)-fat/muscle; (2) up(low)-fat/centrum; (3) up(low)-muscle/centrum; (4) cervical cord compression index (CCI); (5) S-index; and (6) cervical spinal cord compression area ratio (S0/S1). The VAS, NDI and mJOA were used to assess cervical spinal function and quality of life. The patients were divided into 2 groups according to the mJOA score: group A (mild-moderate symptom group, mJOA score≥12 points) and group B (severe symptom group, mJOA score<12 points). The Pearson correlation coefficient was used to assess the correlations between cervical sagittal parameters, MRI parameters and functional scores. Logistic regression analysis and ROC curve analysis were performed to identify independent risk factors and critical values. In patients with CSM, the VAS score is positively correlated with NT, up-fat/centrum, S-index and S0/S1. The NDI is positively correlated with NT, up-fat/muscle, up-fat/centrum, S-index, and S0/S1 and negatively correlated with C0-2N and CL. The mJOA score is positively correlated with CL and negatively correlated with C2-7 SVA, CCI, S-index, and S0/S1. Thus, corresponding segmental paravertebral muscle degeneration has relevance to neck pain, but it is not related to limb weakness, neurological dysfunction, gait impairment, sensation or bladder/bowel function dysfunction. Through mJOA score grouping and binary logistic regression analysis, we found that S0/S1 is the only independent risk factor for severe symptoms in patients with CSM. When S0/S1>0.295, the clinical symptoms of patients are more severe. Thus, in clinical practice, when the degree of spinal cord compression exceeds 30%, the clinical symptoms are more severe. In patients with CSM, corresponding segmental paravertebral muscle degeneration has relevance to neck pain, but it does not relate to limb weakness, neurological dysfunction, gait impairment, sensation or bladder/bowel function dysfunction. Cervical spinal cord compression is the only independent risk factor;when the degree of spinal cord compression exceeds 30%, the clinical symptoms are more severe.

Prevalence of SARS-CoV-2 Antibodies in Children and Adults with Type 1 Diabetes.

Objective: As diabetes is a risk factor for severe symptoms, hospitalization, and death with COVID-19 disease, we aimed to assess the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in children and adults with and without type 1 diabetes in Colorado during 2020. Research Design and Methods: We developed a highly sensitive and specific test for antibodies against SARS-CoV-2 and measured the antibodies in children and adults with new-onset (n = 129) and established type 1 diabetes (n = 94) seen for routine diabetes care at our center between January and October 2020. The antibodies were also measured in 562 children and 102 adults from the general population of Colorado. Results: The prevalence of SARS-CoV-2 antibodies in persons with new-onset type 1 diabetes (0.8%; 95% confidence interval 0.1%-4.2%) or those with established disease (4.3%; 1.7%-10.4%) did not differ from that in the general population children (2.8%; 1.8%-4.6%) or adults (3.9%; 1.5%-9.7%). In a subset of individuals with positive antibodies (n = 31), antibodies remained positive for up to 9 months, although the levels decreased starting 3 months after the infection (P = 0.007). Conclusions: From January to October 2020, the prevalence of SARS-CoV-2 antibodies were not different in children and adults with and without type 1 diabetes in Colorado. We found no evidence for increased prevalence of COVID-19 infections among youth with newly diagnosed type 1 diabetes. (COMIRB Protocol 20-1007).

Structural Racism and Risk of SARS-CoV-2 in Pregnancy: A Local Population Analysis

Background: Structural racism leads to adverse health outcomes, as highlighted by inequities in COVID-19 infections. We characterized black/white disparities among pregnant women with SARS-CoV-2 in a county with some of the most extreme health disparities in the U.S.Methods: This was a retrospective cohort study using data collected as part of public health surveillance.Findings: One hundred and sixty-two women submitted information to the surveillance team from March to October 2020. 81 (50%) were Black, 67 (41%) White, 9 (0.05%) Hispanic, 2 (0·01%) Asian; and three did not self-identify with any particular race. More than half who supplied occupational information (n=132) were essential workers as classified by the CDC definition (55%, n=73). Black women were younger (p=0.0062), more likely to be obese (p=0·052), and more likely to identify an occupational contact as exposing them to SARS-CoV-2 (p=0·020). Non-black women were more likely to work from home (p=0·018) and indicate a personal or household contact as their exposure (p=0·020). Occupation was a risk factor for severe symptoms (aOR 4·487, p = 0·037). Most black women lived in areas with median income Interpretation: Many pregnant women infected by SARS-CoV-2 are essential workers. Black women are more likely than white counterparts to have occupational exposure as the presumed source for their infection. These vocational exposures and limitations in controlling risk could be related to lower socio-economic status, resulting from a long history of structural racism.Funding: NoneDeclaration of Interests: NoneEthics Approval Statement: This study was approved by the institutional review board of University Hospitals Cleveland Medical Center.

The major genetic risk factor for severe COVID-19 is inherited from Neanderthals.

A recent genetic association study1 identified a gene cluster on chromosome3 as a risk locus for respiratory failure after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A separate study (COVID-19 Host Genetics Initiative)2 comprising 3,199 hospitalized patients with coronavirus disease 2019 (COVID-19) and control individuals showed that this cluster is the major genetic risk factor for severe symptoms after SARS-CoV-2 infection and hospitalization. Here we show that the risk is conferred by a genomic segment of around 50kilobases in size that is inherited from Neanderthals and is carried by around 50% of people in south Asia and around 16% of people in Europe.

Anaphylaxis during oral food challenge: can we predict it?

Despite being the gold standard for food allergy diagnosis, oral food challenge (OFC) poses an inherent risk of undesirable reactions, including anaphylaxis. Risk factors for severe symptoms remain unclear. This study aims to describe OFC outcomes to identify possible risk factors for anaphylaxis in this procedure. Retrospective evaluation of medical records from patients with suspected IgE-mediated food allergy to cow’s milk (CM) or egg, who underwent OFC in a pediatric hospital (2016-2018). Patients challenged to either raw or processed CM/egg were included. Anaphylaxis was defined according to Sampson et al, 2006. Data were compared through non-parametric tests 125 OFC (97/CM and 28/egg) carried out in 80 patients (median age of 6.5y) were reviewed. Anaphylaxis was observed in nearly one third of the tests (41). Among these, the first complaint was oropharyngeal pruritus. The most affected systems were cutaneous (82.9%), followed by respiratory (78%), and less frequently cardiovascular (9.7%). Most patients achieved clinical resolution of symptoms after one dose of epinephrine, but five patients required additional doses. One patient had a biphasic anaphylaxis. OFC with raw food compared to processed allergen evidenced similar potential to trigger anaphylaxis (p> 0.05). Personal history of asthma or prior anaphylaxis did not increase the risk of anaphylaxis on OFC (p>0.05). Among patients challenged with raw allergens, older age increased the risk of anaphylaxis (p<0.001). OFC is a high risk setting for anaphylaxis regardless of allergen processing or patient’s medical history. Readiness for emergencies is always mandatory, as severe reactions could not be anticipated.

Risk Factors for Severe Reactions during Double-Blind Placebo-Controlled Food Challenges

Background: Severe anaphylactic symptoms can occur during oral food challenges (OFCs). Thus, high-risk patients (e.g., patients with a history of anaphylaxis or high antigen-specific immunoglobulin E [IgE] levels) must carefully undergo OFCs in hospitals. We attempted to identify the risk factors for severe symptoms during OFC testing among high-risk patients. Methods: We retrospectively evaluated patients' characteristics and severe symptoms that were experienced during a double-blind placebo-controlled food challenge test performed before the patients underwent oral immunotherapy between June 2008 and June 2012. Patients were ≥5 years old and had an anaphylactic history or antigen-specific IgE (>30 kUA/L). Severe symptoms were defined using the grading of the Japanese Anaphylaxis Guidelines, which are modified from the European Academy of Allergology and Clinical Immunology Guidelines. Results: We evaluated 393 cases with positive test results, including 98 cases with severe symptoms. The most frequent severe symptoms were respiratory (77%), gastrointestinal (28%), cardiovascular (27%), and neurological (13%) symptoms. Multivariate analysis revealed that the significant factors for a severe reaction were a history of anaphylaxis to the causative food (adjusted odds ratio [OR]: 2.147, p = 0.003), older age (per 1 year increase, adjusted OR: 1.102, p = 0.044), and an egg OFC (adjusted OR: 0.433, p = 0.003). Conclusions: The risk factors for a severe reaction to OFCs were a history of an anaphylactic reaction and older age. An egg OFC was associated with low risk of severe symptoms during OFC. Therefore, OFCs for patients with these risk factors should only be performed under specialist supervision with access to rapid treatment and full resuscitation equipment.

Severe allergic symptoms to peach are a risk factor for severe symptoms to other plant food allergens

Objective A group of 148 peach allergic patients, recruited in a ongoing clinical study (Clinical Trials.gov, protocol ID NCT00715156) aimed at studying the relationship between the clinical manifestations to peach and the positivity to different peach major allergens (Pru p 3, 1 and 4), were divided into 2 groups according to peach induced symptoms: group A (mild-OAS; 76 pts) and group B (severe-OAS with systemic symptoms, 72 pts). These patients were examined to see if severe allergic symptoms to peach were a risk factor for developing severe symptoms to other plant foods allergens.

Clinical Escherichia coli strains carrying stx genes: stx variants and stx-positive virulence profiles.

Altogether, 173 Shiga toxin-producing Escherichia coli (STEC) serotype O157 (n = 111) and non-O157 (n = 62) isolates from 170 subjects were screened by PCR-restriction fragment length polymorphism for eight different stx genes. The results were compiled according to serotypes, phage types of O157, production of Stx toxin and enterohemolysin, and the presence of eae. The stx genes occurred in 11 combinations; the most common were stx(2) with stx(2c) (42%), stx(2) alone (21%), and stx(1) alone (16%). Of the O157 strains, 64% carried stx(2) with stx(2c) versus 2% of the non-O157 strains (P < 0.001). In the non-O157 strains, the prevailing gene was stx(1) (99% versus 1% in O157 strains; P < 0.001). In addition, one strain (O Rough:H4:stx(2c)) which has not previously been described as associated with hemolytic-uremic syndrome (HUS) was found. Ten stx-positive virulence profiles were responsible for 71% of all STEC infections. Of these profiles, five accounted for 71% of the 21 strains isolated from 20 patients with HUS or thrombotic thrombocytopenic purpura (TTP). The strains having the virulence profile that caused mainly HUS or TTP or bloody diarrhea produced Stx with titers of >/=1:128 (90%) more commonly than did other strains (51%; P < 0.001). These strains were also more commonly enterohemolytic (98% versus 68% for other strains; P < 0.001) and possessed the eae gene (100%) more commonly than did other strains (74%; P < 0.001). A particular virulence profile, O157:H7:PT2:stx(2):stx(2c):eae:Ehly, was significantly more frequently associated with HUS and bloody diarrhea than were other profiles (P = 0.02) and also caused the deaths of two children. In this study, the risk factors for severe symptoms were an age of <5 years and infection by the strain of O157:H7:PT2 mentioned above.

Relationship between radiological and clinical variables in spondylolysis.

A clinical and radiological follow-up investigation with at least 20 years observation time was made of 255 persons with lumbar spondylolysis with or without spondylolisthesis. The main purposes were to study the relationship between clinical and radiological features and to look for radiological and other variables of prognostic value. There was a clear positive correlation of symptoms and functional impairment during the observation period to disc degeneration and vertebral slipping at follow-up, as well as to a decrease in lumbar index at the time of diagnosis. Individual factors and radiological signs at the time of diagnosis were shown to have prognostic value for the course of the disease. The risk factors for severe symptoms and need for treatment were more than 10 mm of vertebral slipping, low lumbar index, increased lumbar lordosis, lysis in the fourth lumbar vertebra and early onset of symptoms.
