Simple tests of routine data are needed in those with coronavirus 2 (SARS-CoV-2) 2019, or COVID-19 to help identify those you may need mechanical ventilation (MV).

To determine if FIB-4 is associated need for MV in a multi-ethnic, national cohort of patients with COVID-19 and if so, to determine the optimal FIB-4 cutoff.

This was a retrospective national cohort study of adults seen in an ambulatory or emergency department setting diagnosed with COVID-19 identified using the TriNetX platform. Measures included demographics, comorbid diseases, and routine laboratory tests.

A total of 4901 patients with COVID-19 were included mean age was 56, 48% female, 42% obese, 38% White, 40% Black, cardiac disease 15%, diabetes mellitus (DM) 39%, liver disease 20%, and respiratory disease 50%. Need for MV was 6%. The optimal cutoff FIB-4 for need for mechanical ventilation was 3.04 (AUC 0.735) which had a sensitivity, specificity, positive and negative predictive values of 42%, 77%, 11%, and 95%, respectively with 93% accuracy. When stratified by race, increased FIB-4 remained associated with need for mechanical ventilation in both Whites and Blacks.

FIB-4 can be used by front line providers to identify which patients may require MV.

Currently, most SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) clinical testing is voluntary and inconsistently available, except for a few occupational and educational settings, and therefore likely underrepresents actual population prevalence. Randomized testing on a regular basis to estimate accurate population-level infection rates is prohibitively costly and is hampered by a range of limitations and barriers associated with participation in clinical research. In comparison, community-level fecal monitoring can be performed through wastewater surveillance to effectively surveil communities. However, epidemiologically defined protocols for wastewater sample site selection are lacking. Herein, we describe methods for developing a geographically resolved population-level wastewater sampling approach in Jefferson County, Kentucky, and present preliminary results. Utilizing this site selection protocol, samples (n = 237) were collected from 17 wastewater catchment areas, September 8 to October 30, 2020 from one to four times per week in each area and compared to concurrent clinical data aggregated to wastewater catchment areas and county level. SARS-CoV-2 RNA was consistently present in wastewater during the studied period, and varied by area. Data obtained using the site selection protocol showed variation in geographically resolved wastewater SARS-CoV-2 RNA concentration compared to clinical rates. These findings highlight the importance of neighborhood-equivalent spatial scales and provide a promising approach for viral epidemic surveillance, thus better guiding spatially targeted public health mitigation strategies.The spectral computed tomography (CT) has huge advantages by providing accurate material information. Unfortunately, due to the instability or overdetermination of material decomposition model, the accuracy of material decomposition can be compromised in practice. Very recently, the dictionary learning based image-domain material decomposition (DLIMD) can obtain high accuracy for material decompositions from reconstructed spectral CT images. This method can explore the correlation of material components to some extent by training a unified dictionary from all material images. In addition, the dictionary learning based prior as a penalty is applied on material components independently, and many parameters would be carefully elaborated in practice. Because the concentration of contrast agent in clinical applications is low, it can result in data inconsistency for dictionary based representation during the iteration process. To avoid the aforementioned limitations and further improve the accuracy of materials, we first construct a generalized dictionary learning based image-domain material decomposition (GDLIMD) model. Then, the material tensor image is unfolded along the mode-1 to enhance the correlation of different materials. DOTAP chloride Finally, to avoid the data inconsistency of low iodine contrast, a normalization strategy is employed. Both physical phantom and tissue-synthetic phantom experiments demonstrate the proposed GDLIMD method outperforms the DLIMD and direct inversion (DI) methods.
This study aims to investigate the effects of COVID-19 on epidemiological features, burn agent, burn percentage, and hospitalization time in a burn center.

This single-center, retrospective study included a total of 401 patients admitted to our study center between October 2019 and July 2020. The patients who were admitted before March 1, 2020, were considered the pre-March group, and those who were admitted after March 1, 2020, were considered the post-March group. According to their age, the patients were further divided into groups as those aged≤18years and those aged>18years. Demographic and clinical characteristics of patients, burn agent, burn surface area, COVID-19 status, and treatment and follow-up data were recorded.

Our study results showed no significant difference in the number of patient admission, age, and sex of patients, burn agents and length of hospital stay before and after the COVID-19 outbreak.

Burn centers can work safely in COVID-19 outbreak, paying special attention to precautions mandated by the national and global health authorities. However, the increase in pandemic burden may force the burn centers to be converted into alternate COVID-19 facilities. In such cases, the care of burn patients may pose a great problem.
