Racial disparities in symptomatology and outcomes of COVID-19 among adults of Arkansas

The Association Between Dietary Supplement Use and COVID-19 Symptoms

The scientific evidence supporting recommendations for dietary supplement use to prevent or treat coronavirus disease 2019 (COVID‑19) is not well‑established. This cohort study investigates the relationship between dietary supplement usage and COVID‑19 symptoms among 27,181 adults tested for COVID‑19. Using data from surveys following COVID‑19 testing, conducted by the University of Arkansas for Medical Sciences, associations between dietary supplement usage, symptomatology, and COVID‑19 status were explored. The prevalence of supplement consumption among symptomatic individuals was significant, with non‑Hispanic (NH)‑White individuals showing higher usage rates. Among those testing positive for COVID‑19, mainly asymptomatic cases, dietary supplement usage was increased (7.8%), suggesting a proactive approach to supplementation. Symptomatic individuals with confirmed COVID‑19 also showed heightened dietary supplement usage (37.9%), indicating a response to perceived therapeutic benefits. Notably, respiratory symptoms such as cough (46.2%), fever (31.4%), and shortness of breath (8.9%) correlated consistently with increased dietary supplement usage across different time points. Despite limitations such as varying test sensitivities and potential selection biases, this study offers valuable insights into individual health‑seeking behaviors during the pandemic. Findings emphasize the importance of targeted public health interventions and education to address disparities in dietary supplement usage and promote evidence‑based approaches to dietary supplementation. Further research is warranted to understand better the motivations and implications of dietary supplement usage in the context of the pandemic.

Factors associated with loss and recovery of smell and taste after COVID-19 infection

Objective

To identify predictors associated with loss and recovery of smell and taste after COVID-19 infection.

Methods

The Integrated Public Use Microdata Series (IPUMS) 2021 National Health Interview Series (NHIS) database was used to analyze factors associated with loss and recovery of smell and taste in respondents who had a previous COVID-19 infection. Significant variables from univariate analysis were included in a stepwise backward regression model to identify independent predictors.

Results

Of the 3844 individuals who answered yes to having contracted COVID-19, 51.1% and 48.9% reported losing smell and taste, respectively. 95.7% recovered smell and 97% recovered taste. Predictors associated with higher odds of reporting a loss of smell included younger age (odds ratio [OR] 0.98; 95% confidence interval [CI] 0.98-0.99), female sex (OR 1.38; CI 1.17-1.63), use of e-cigarettes (OR 1.59; CI 1.25-2.02), and Mexican ethnicity (OR 1.61; CI 1.22-2.11). Predictors of taste loss were younger age (OR 0.98; CI 0.98-0.99), female sex (OR 1.31; CI 1.08-1.58), and higher BMI (OR 1.02; CI 1.00-1.04). Female sex was associated with decreased odds of reporting a recovery of smell (OR 0.74; CI 0.59-0.92) and taste (OR 0.54; CI 0.42-0.69). Black/African American race (OR 1.44; CI 1.03-2.03) and non-Mexican Hispanic ethnicities (OR 1.55; CI 1.02-2.34) were associated with an increased likelihood of reporting the recovery of smell.

Conclusion

Various factors may be associated with the loss and recovery of smell and taste after COVID-19 infections. Clinicians may use this information to better counsel patients with these symptoms.

Headaches and facial pain attributed to SARS-CoV-2 infection and vaccination: a systematic review

BACKGROUND AND PURPOSE

The aim was to provide insights to the characteristics of headache in the context of COVID-19 on behalf of the Headache Scientific Panel and the Neuro-COVID-19 Task Force of the European Academy of Neurology (EAN) and the European Headache Federation (EHF).

METHODS

Following the Delphi method the Task Force identified six relevant questions and then conducted a systematic literature review to provide evidence-based answers and suggest specific diagnostic criteria.

RESULTS

No data for facial pain were identified in the literature search. (1) Headache incidence during acute COVID-19 varies considerably, with higher prevalence rates in prospective compared to retrospective studies (28.9%-74.6% vs. 6.5%-34.0%). (2) Acute COVID-19 headache is usually bilateral or holocranial and often moderate to severe with throbbing pain quality lasting 2-14 days after first signs of COVID-19; photo-phonophobia, nausea, anosmia and ageusia are common associated features; persistent headache shares similar clinical characteristics. (3) Acute COVID-19 headache is presumably caused by immune-mediated mechanisms that activate the trigeminovascular system. (4) Headache occurs in 13.3%-76.9% following SARS-CoV-2 vaccination and occurs more often amongst women with a pre-existing primary headache; the risk of developing headache is higher with the adenoviral-vector-type vaccines than with other preparations. (5) Headache related to SARS-CoV-2 vaccination is mostly bilateral, and throbbing, pressing, jolting or stabbing. (6) No studies have been conducted investigating the underlying mechanism of headache attributed to SARS-CoV-2 vaccines.

CONCLUSION

The results of this joint EAN/EHF initiative provide a framework for a better understanding of headache in the context of SARS-CoV-2 infection and vaccination.

Headache in COVID-19 and Long COVID: to Know Facts for Clinical Practice

PURPOSE OF REVIEW

Headache is one of the most frequent symptoms of the acute and post-acute phase of COVID-19. Specific epidemiology, clinical features, risk factors, pathophysiology, and treatment have been reported in these two scenarios. With this narrative review of the literature, we aim to provide updated knowledge on headache in the COVID-19 setting and give clinicians a practical approach on this topic to guide them in their clinical practice.

RECENT FINDINGS

Headache mechanisms in COVID-19 are still poorly understood. Strong evidence is also lacking on how to best treat and manage these patients, especially those with persistent and disabling headache after COVID-19. Data are also scarce on the characteristics of headache in COVID-19 caused by the new SARS-CoV-2 (Omicron) variants and how these may influence the acute and persistent symptoms of COVID-19. Patients with pre-existing primary headache disorders remain a particularly concerning population due to their biological predisposition in suffering from headaches and the potential risk of worsening in the setting of SARS-CoV-2 infection. Although there is an exponential growth of scientific evidence, studies are often controversial and focused on the first wave of the pandemic, making COVID-19 headache still a challenging matter for clinicians. New research is therefore needed.

Characterizing Risk Factors for Hospitalization and Clinical Characteristics in a Cohort of COVID-19 Patients Enrolled in the GENCOV Study

The GENCOV study aims to identify patient factors which affect COVID-19 severity and outcomes. Here, we aimed to evaluate patient characteristics, acute symptoms and their persistence, and associations with hospitalization. Participants were recruited at hospital sites across the Greater Toronto Area in Ontario, Canada. Patient-reported demographics, medical history, and COVID-19 symptoms and complications were collected through an intake survey. Regression analyses were performed to identify associations with outcomes including hospitalization and COVID-19 symptoms. In total, 966 responses were obtained from 1106 eligible participants (87% response rate) between November 2020 and May 2022. Increasing continuous age (aOR: 1.05 [95%CI: 1.01-1.08]) and BMI (aOR: 1.17 [95%CI: 1.10-1.24]), non-White/European ethnicity (aOR: 2.72 [95%CI: 1.22-6.05]), hypertension (aOR: 2.78 [95%CI: 1.22-6.34]), and infection by viral variants (aOR: 5.43 [95%CI: 1.45-20.34]) were identified as risk factors for hospitalization. Several symptoms including shortness of breath and fever were found to be more common among inpatients and tended to persist for longer durations following acute illness. Sex, age, ethnicity, BMI, vaccination status, viral strain, and underlying health conditions were associated with developing and having persistent symptoms. By improving our understanding of risk factors for severe COVID-19, our findings may guide COVID-19 patient management strategies by enabling more efficient clinical decision making.

Racial, ethnic, and sex disparities in the incidence and cognitive symptomology of long COVID-19

BACKGROUND

The pandemic has highlighted and exacerbated health inequities in both acute coronavirus disease 2019 (COVID-19) and its longer-term sequelae. Given the heterogeneity in definitions of long COVID and the lack of centralized registries of patients with the disease, little is known about the differential prevalence among racial, ethnic, and sex subgroups. This study examines long COVID among Black, White, Asian, and Hispanic Americans and evaluates differences in the associated cognitive symptomology.

METHOD

Data from four releases of the Census Bureau's Household Pulse Survey detailing COVID-19 incidence and the duration and type of symptoms among a nationally representative sample of adults from June 1, 2022, through October 17, 2022, were combined. Binary logistic regression assessed the relative likelihood of long COVID among those who had been diagnosed COVID between racial, ethnic, and sex subgroups. Among those reporting long COVID, differences in the prevalence of difficulty understanding and difficulty remembering were assessed. Empirical models accounted for household, regional, vaccination, and insurance differences between respondents. Two-stage selection models were applied to test the robustness of the results.

RESULTS

Among respondents who tested positive for COVID-19, Blacks (OR=1.097, CI=1.034-1.163), females (OR=1.849, CI=1.794-1.907), and Hispanics (OR=1.349, CI=1.286-1.414) were more likely to experience long COVID (symptoms lasting for 3 months or longer) compared to Whites, males, and non-Hispanics respectively. However, those with private health insurance (OR=0.634, CI=0.611-0.658) and who received the COVID vaccine (OR=0.901, CI=0.864-0.94) were less likely to have endured COVID symptoms than their counterparts. Symptoms of long COVID varied significantly between population subgroups. Compared to Whites, Blacks were more likely to have trouble remembering (OR=1.878, CI=1.765-1.808) while Hispanics were more likely to report difficult understanding (OR=1.827, CI=1.413, 2.362). Females, compared to males, were less likely to experience trouble understanding (OR=0.664, CI=0.537, 0.821), but more likely to report trouble remembering (OR=1.34, CI=1.237, 1.451).

CONCLUSIONS

Long COVID is more prevalent among Blacks, Hispanics, and females, but each group appears to experience long COVID differently. Therefore, additional research is needed to determine the best method to treat and manage this poorly understood condition.
