A seroconversion panel was generated from a single SARS-CoV-2 positive plasma donor over 87 days. This seroconversion panel was tested against 6 SARS-CoV-2 antibody tests (IgG, IgM, and total Ig). All test kits utilized recombinant antigens that are specific to SARS-CoV-2. The seroconversion panel showed IgG responses for SARS-CoV-2 after day 50. IgM levels peaked on day 50 (prior to IgG) and declined in subsequent samples. This seroconversion panel is a useful tool for validation of SARS-CoV-2 antibody assays.

Well-child care is the foundation of pediatric health promotion and disease prevention. Primary care quality is lower for low-income and African American children compared to white children, and social determinants have an increasingly acknowledged impact on child health. Ensuring that high-quality well-child care fulfills its potential to mitigate the negative effects of social determinants on African American children is imperative. This study provides an understanding of urban, low-income, African American well-child care experiences and expectations.

A qualitative, focus group method was used. A purposive, volunteer sample of low-income, African American parents with children birth to age five was recruited from St. Louis and Milwaukee. Focus groups were held in convenient, community sites. Data was audio-digitally recorded. Transcribed data were coded and analyzed through inductive content analysis.

Thirty-five caregivers, 86% females, participated in four focus groups. Categories (and sub-categories) identified include Community factors (We want better schools, It's getting more rough where I live); Sources of parenting advice (Google it, Call your parent, Older remedies); System challenges (Cost, Frequent new faces, Politics); Challenges with providers (Couldn't help me, Missed something important, Treated differently, Are you really listening?); Anticipatory guidance (Breastfeeding, Discipline, Vaccines, Development); and What parents desire (Know them, trust).

This study reveals the contexts that give rise to health care disparities and provides insight into parent's healthcare behaviors.

Results offer providers guidance in providing well-child care for this population to improve pediatric care quality and child health.

Since its symptoms are not clear and commonly confused with other diseases, providing early diagnosis is a challenging task for traditional methods. In this context, computer-aided assistance is an alternative method for a fast and automatic diagnosis, accelerating the treatment and alleviating an excessive effort from professionals. Moreover, the most recent studies proposing a solution to this problem lack in computational efficiency, prediction power, reliability among other factors. Therefore, this work proposes a Fuzzy Optimum Path Forest for automated PD identification, which is based on fuzzy logic and graph-based framework theory. Experiments consider a dataset composed of features extracted from hand-drawn images using Restricted Boltzmann Machines, and results are compared with baseline models such as Support Vector Machines, KNN, and the standard OPF classifier. Results show that the proposed model outperforms the baselines in most cases, suggesting the Fuzzy OPF as a viable alternative to deal with PD detection problems.Single-molecule real-time DNA sequencing revealed that 4-methylcytosine (m4C) commonly exists in bacterial genomes. In this work, samples with different m4C methylation patterns were studied. Results reveal that m4C modification is a biochemical reaction with distance effect, and its distribution follows the power function in the positive, negative, and double strands of genomic DNA sequences of Geobacter sulfurreducens. Furthermore, the value of regression coefficient in the fitting formula for double strands was the sum of those in the fitting formulae for positive and negative strands. Meanwhile, the value of exponent coefficient was the average, implicating an interesting mathematical phenomenon about power function. Considering the potent role of m4C in gene expression and the present results being obtained from the same genomic DNA sequence, this work suggests that the patterns of m4C distribution may be served as a signal for G. sulfurreducens to rapidly identify the genes to respond to environmental stresses or signals. This study opens a new avenue to extend our knowledge about the modification mechanisms and the epigenetic information of m4C modification in prokaryotes.

To compare the socio-demographic, clinical, and diagnostic characteristics and treatment outcomes between extrapulmonary tuberculosis (EPTB) and pulmonary tuberculosis (PTB) in children and adolescents in Rio de Janeiro, a high TB-burdened Brazilian city.

This retrospective study used data from patients with EPTB and PTB aged 0 - 18 years, notified on two national databases from 2014 to 2016.

Among the 1008 patients, 144 (14.2%) had EPTB. Patients with EPTB showed higher odds of hospital-based diagnosis (odds ratio (OR) 6.76 [95% confidence interval (95% CI) 4.62-9.90]; p < 0.001), no laboratory confirmation (OR 4.9 2.14 [95% CI 3.07 - 7.85]; p < 0.001), and being <14 years old (OR 3.13 [95% CI 2.18-4.49]) than those with PTB. A diagnosis without laboratory investigation was observed among 301/864 (34.8%) patients with PTB, 48/144 (33.3%) with EPTB, and among those aged under five years with EPTB (15/27 [55.6%]). TB deaths were more frequent in patients with EPTB (5/144 [3.5%]) than in those with PTB (4/864[0.5%]) (p = 0.001); 4/5 (80%) TB deaths were due to TB meningitis; 50% died within 14 days of diagnosis.

EPTB remains a clinical diagnostic challenge that needs to be addressed to fully benefit from the higher sensitivity laboratory investigations.

To explore the mechanisms of interferon-induced transmembrane protein 3 (IFITM3) in response to enterovirus-71-associated hand, foot and mouth disease (EV71-HFMD), in terms of DNA methylation, single-nucleotide polymorphism (SNP) genotype and gene expression.

In total, 120 patients with EV71-HFMD (60 with mild EV71-HFMD and 60 with severe EV71-HFMD) and 60 healthy controls were enrolled in this study. SNP genotype, IFITM3 promoter methylation and mRNA expression of peripheral blood mononuclear cells were examined using the improved multi-temperature ligase detection reaction, quantitative reverse transcriptase polymerase chain reaction and MiSeq, respectively.

The distribution of methylation in patients with EV71-HFMD was significantly lower compared with healthy controls, and the severe EV71-HFMD group showed the lowest frequency of IFITM3 promoter methylation. The average level of IFITM3 promoter CpG methylation was negatively correlated with IFITM3 mRNA expression, and hypermethylation of several specific CpG units contributed to IFITM3 downregulation. IFITM3 expression and promoter methylation correlated with EV71 infection progression, especially in the severe EV71-HFMD group. Compared with mild cases, genotype GG and the G allele of rs12252 were over-represented in patients with severe EV71-HFMD.

IFITM3 methylation status and SNP genotyping may help clinicians to choose the correct treatment strategy for patients with EV71-HFMD.

Rotavirus (RV) genotypes vary geographically, and this can affect vaccine effectiveness (VE). This study investigated the genotype distribution of RV and explored VE before introducing the RV vaccine to the national immunization programme in Vietnam.

This hospital-based surveillance study was conducted at Children's Hospital 1, Ho Chi Minh City in 2013-2018. Stool samples and relevant data, including vaccination history, were collected from children aged <5 years who were hospitalized with gastroenteritis. RV was detected using enzyme immunoassays and then genotyped. Children aged ≥6 months were included in the VE analysis.

Overall, 5176 children were included in this study. RV was detected in 2421 children (46.8%). RV positivity decreased over the study period and was associated with age, seasonality, location and previous vaccination. Among 1105 RV-positive samples, G3P[8] was the most prevalent genotype (43.1%), followed by G8P[8] (19.7%), G1P[8] (12.9%) and G2P[4] (12.9%). Overall VE was 69.7% [95% confidence interval (CI) 53.3-80.6%] in fully vaccinated children and 58.6% (95% CI 44.1-69.4%) in children who had received at least one dose of RV vaccine. VE was highest for G3P[8] (95% CI 75.1-84.5%) and lowest for G2P[4] (95% CI 32.4-57.2%).

RV remains a major cause of acute gastroenteritis requiring hospitalization in southern Vietnam. The RV vaccine is effective, but its effectiveness varies with RV genotype.

Lengthy research efforts have brought important lessons on its particular epidemiology the heterogeneous levels of transmission, the large reservoir of both asymptomatic and submicroscopic infections, the co-transmission of Plasmodium vivax and Plasmodium falciparum in the same areas, and the limitations of current diagnostics. Based on these features, the national elimination program could greatly benefit from simplified standard treatment, with the use of artemisinin-based combination therapy and even shorter schemes of primaquine maintaing the total dosing. It is acknowledged that there is some uncertainty regarding the true prevalence of glucose-6-phosphate dehydrogenase deficiency (G6PD) and genetic polymorphisms related to cytochrome P-450 isozyme 2D6 functioning. Once we have a better understanding, tafenoquine, whether or not in combination with a rapid G6PD enzyme test, may become a future pathway to eliminate the otherwise hidden reservoir of the P. vivax hypnozoite through one standard Plasmodium treatment.Candida albicans is a commensal organism and opportunistic pathogen that can form biofilms that colonize surfaces of medical devices, such as implants, catheters, and dentures. Compared to planktonic C. albicans cells, cells in biofilms exhibit increased resistance to treatment. Histatin 5 (Hst-5) is an antimicrobial peptide that is natively secreted by human salivary glands and has strong antifungal activity against C. albicans. However, C. albicans produces secreted aspartic proteases (Saps) that can cleave and inactivate Hst-5, limiting its antifungal properties. Selleckchem UNC1999 We previously showed that residue substitutions K11R and K17R within Hst-5 improve its antifungal activity and prevent proteolytic degradation by Saps when treating planktonic C. albicans. Here, we investigated the use of the K11R-K17R peptide as an alternative therapeutic against C. albicans biofilms by assessing its ability to reduce viability of pre-formed biofilms and to inhibit the formation of biofilms and showed that K11R-K17R had improved activity compared to Hst-5.
