023) and scored lower on the 12-item Psoriatic Arthritis Impact of Disease questionnaire (p=0.012). On the Skindex-17 psychosocial subscale, 31% experienced moderate to high impairment and on the symptoms subscale 28% experienced a lot of symptoms. Work productivity did not differ between both groups.

The majority of patients with DAPSA-LDA and active psoriasis after one year has a good HRQoL. However, a proportion of these patients still experiences considerable skin burden. We recommend rheumatologists to continue assessing and treating psoriasis to reduce skin burden in PsA patients who achieved musculoskeletal low disease activity.

We aimed to assess SARS-CoV-2 spike-specific antibody kinetics postvaccination and the benefit of a mRNA vaccine booster dose in rheumatoid arthritis (RA) patients treated with immunosuppressive drugs.

Consecutive RA patients on immunosuppressive therapies, with no known history of SARS-CoV-2 infection or high-risk contact, vaccinated with 2 doses SARS-CoV-2 mRNA, BNT162b2 or mRNA-1273, or viral vectored ChAdOx1 nCoV-19 vaccine were recruited during their routine rheumatology consultation. Anti-SARS-CoV-2 IgG spike-specific antibodies were quantified at 1, 3 and 6 months respectively following the second vaccine dose. The incidence of SARS-CoV-2 infection post-vaccination during this 6-month longitudinal study was also assessed.

Of the 104 RA patients included, 79 patients completed the 6-month trial follow-up. A significant decrease in anti-SARS-CoV-2 spike-specific IgG titres was observed between 1-month and 3-month postvaccination (p<0.01). Among the 46 patients (46/79) receiving a booster dose, aer dose in a cohort of RA patients. The latter is essential given the waning humoral immunity observed in vaccinated RA patients and the increased incidence of COVID-19 diseases postvaccination in this 6-month longitudinal study.H5N1 avian influenza viruses bearing the clade 2.3.4.4b hemagglutinin gene have been widely circulating in wild birds and are responsible for the loss of over 70 million domestic poultry in Europe, Africa, Asia, and North America since October 2020. During our routine surveillance, 13 H5N1 viruses were isolated from 26,767 wild bird and poultry samples that were collected between September 2021 and March 2022 in China. To investigate the origin of these Chinese isolates and understand their genetic relationship with the globally circulating H5N1 viruses, we performed a detailed phylogenic analysis of 233 representative H5N1 strains that were isolated from 28 countries. We found that, after they emerged in the Netherlands, the H5N1 viruses encountered complicated gene exchange with different viruses circulating in wild birds and formed 16 genotypes. Genotype one (G1) was predominant, being detected in 22 countries, whereas all other genotypes were only detected in one or two continents. H5N1 viruses of four genotypes (G1, G7, G9, and G10) were detected in China; three of these genotypes have been previously reported in other countries. The H5N1 viruses detected in China replicated in mice, with pathogenicity varying among strains; the G1 virus was highly lethal in mice. Moreover, we found that these viruses were antigenically similar to and well matched with the H5-Re14 vaccine strain currently used in China. Our study reveals the overall picture of H5N1 virus evolution and provides insights for the control of these viruses.
To assess (a) the impacts of fibromyalgia (FM) symptoms on patients' ability to work and (b) the relationship between FM severity states and lost productivity from the perspective of patients.

FM female patients were retrospectively evaluated for this cross-sectional study. FM severity was determined using the revised Fibromyalgia Impact Questionnaire (FIQR). Work Productivity and Activity Impairment-Fibromyalgia (WPAI-FM) was used to evaluate patients' employment status. Differences across FM severity states were evaluated using the one-way analysis of variance (ANOVA) and chi-square or Fisher's exact test. The Pearson's r test was performed for the correlation analysis.

The study included 209 subjects, 64 (30.6%) had mild, 64 (30.6%) had moderate, and 81 (38.8%) had severe FM; 57.9% were working full-time, and 42.1% were working part-time. According to WPAI-FM the work productivity and activity impairment resulted absenteeism 7.03%; presenteeism 44.35%; activity impairment 47.24%; overall work productivity loss 58.23%. Disease severity was associated with decreased work productivity. Presenteeism, overall work productivity loss, and activity impairment demonstrated significant correlations with FIQR and PainDETECT Questionnaire.

FM severity is associated to a reduced job productivity. Early identification and treatment of FM may provide a window of opportunity for job preservation.

A series of sixteen types of hydroxylated TiO2 surfaces containing two types of hydroxyls (OH1 and OH2) on four kinds of low index surfaces [(001), (100), (101), and (110)] of two types of crystals [anatase (A) and rutile (R)] are studied using first-principles density functional theory calculations. The catalyzed splitting of H2O and H2 on the eight low index surfaces is compared using Gibbs free energy. The geometries and electronic structures including the total and partial density of states and the charge density distribution of the sixteen hydroxylated surfaces are systematically described. The electronic structures of R-101, R-001, A-110, A-100, and A-001 surfaces are more significantly influenced by hydroxylation than other surfaces and the effects of OH2 are larger than those of OH1. In particular, the band gap values decrease and a new electronic energy state appears in R-001-OH2 and A-100-OH2. A new electronic state appears in the middle of the bands of R-101 and A-110 surfaces upon hydroxylation. The electron spin balance at the edge of the conduction band minimum of A-001-OH2 is disturbed. This research can provide theoretical guidance for experimental researchers to design surface hydroxylated TiO2 materials with tunable electronic structures and high catalytic performance.Cognitive impairment may persist in HIV patients despite effective antiretroviral therapy (ART). However, recovery is influenced by the neurocognitive domain tested, the severity of HIV disease, and by education. In young adult patients commencing ART in Jakarta, Indonesia, we described improvements in all cognitive domains except memory after 6-12 months on ART. In this study, we address relationships between cytomegalovirus (CMV), γδ T cell profiles and neurocognitive assessments with a focus on memory. The JakCCANDO (Jakarta CMV Cardiovascular ART Neurology Dentistry Ophthalmology) project recruited patients (aged 18-48 years) beginning ART with less then 200 CD4+ T cells/μL. Cognitive assessments used validated tests of five domains. Flow cytometry was used to assess proportions of Vδ2- and Vδ2+ γδ T cells, and their activation (HLA-DR) and terminal differentiation (CD27-/CD45RA+). All patients carried high levels of antibodies reactive with CMV, so the detection of CMV DNA before ART was used to stratify participants into subgroups with a moderate/high or an extremely high burden of CMV. Patients had higher proportions of Vδ2- γδ T cells and fewer Vδ2+ γδ T cells than healthy controls before ART and at 6 months. Z-scores for memory function correlated with proportions of Vδ2+ γδ T cells at both time points. Linear regression analyses confirmed this association. When the detection of CMV DNA was used to stratify the cohort, the association between memory Z-scores and Vδ2+ γδ T cells or CMV antibodies was only discernible in patients with a lower CMV burden. Hence, CMV and Vδ2+ γδ T cells warrant further consideration as factors that may contribute to the poor recovery of memory on ART.
To evaluate the effect of potential confounders on the association between sex and disease impact in recent-onset psoriatic arthritis.

We performed a multicentre observational prospective study (2-year follow-up, regular annual visits). The study population comprised patients aged ≥18 years who fulfilled the CASPAR criteria and less than 2 years since the onset of symptoms. The dataset was generated using data for each patient at the 3 visits (baseline, first year, and second year of follow-up) matched with the PsAID values at each of the 3 visits. Once variables associated with both PsAID ≥4 and sex were selected, those that led to a difference of >10% between the adjusted and crude estimations were identified as potential confounders in the association between sex and PsAID. Lastly, the final multivariate logistic regression model estimating the association between sex and PsAID was defined.

The dataset contained 418 observations (158 at baseline, 135 at the first follow-up visit, and 125 at the second visit). The confounders identified in the multivariate model were HAQ, global pain, level of physical activity, and joint pattern at diagnosis. After adjustment for these variables, no statistically significant association was observed between female sex and PsAID ≥4.

The association between female sex and greater disease impact could be explained by the influence of other variables, specifically higher HAQ score, greater intensity of pain, differences in the level of physical activity and in the joint pattern at diagnosis (lower frequency of the spondylitis pattern in women).

We then recount evidence that TH metabolism participates in maintaining the appropriate content of active hormone in a TH-responsive tissue or cell. Thus, metabolism of the TH is not merely a means by which it is degraded and eliminated from the body, but an essential component of an intricate system by which the thyroid exerts its multiple regulatory effects on almost all organs and tissues. The article ends with a summary of the current concepts and some outstanding questions that are awaiting answers.
