Towards understanding post-COVID-19 condition: A systematic meta-analysis of transcriptomic alterations with sex-specific insights.

BACKGROUND: Post COVID-19 Condition (PCC), characterized by lingering symptoms post-acute COVID-19, poses clinical challenges, highlighting the need to understand its underlying molecular mechanisms. This meta-analysis aims to shed light on the transcriptomic landscapes and sex-specific molecular dynamics intrinsic to PCC. METHODS: A systematic review identified three studies suitable for comprehensive meta-analysis, encompassing 135 samples (57 PCC subjects and 78 recovered subjects). We performed meta-analysis on differential gene expression, a gene set enrichment analysis of Reactome pathways, and weighted gene co-expression network analysis (WGCNA). We performed a drug and disease enrichment analysis and also assessed sex-specific differences in expression patterns. KEY FINDINGS: A clear difference was observed in the transcriptomic profiles of PCC subjects, with 530 differentially expressed genes (DEGs) identified. Enrichment analysis revealed that the altered pathways were predominantly implicated in cell cycle processes, immune dysregulation and histone modifications. Antioxidant compounds such as hesperitin were predominantly linked to the hub genes of the DEGs. Sex-specific analyses highlighted disparities in DEGs and altered pathways in male and female PCC patients, revealing a difference in the expression of ribosomal proteins. PCC in men was mostly linked to neuro-cardiovascular disorders, while women exhibited more diverse disorders, with a high index of respiratory conditions. CONCLUSION: Our study reveals the intricate molecular processes underlying PCC, highlighting that the differences in molecular dynamics between males and females could be key to understanding and effectively managing the varied symptomatology of this condition.

Characterization of Burnout Among Spanish Family Physicians Treating Fibromyalgia Patients: The EPIFFAC Study.

OBJECTIVE: Burnout among physicians has increased, affecting not only doctors but also the quality of patient care. Treating challenging disorders, such as fibromyalgia, may increase the risk of feeling burned out. Health care of fibromyalgia patients is increasingly being assigned to family physicians. Therefore, we described the demographic characteristics, work contexts, component burnout scores (exhaustion, depersonalization, and personal accomplishment), and perceptions of fibromyalgia care of Spanish family medicine physicians with high and low levels of burnout. We then evaluated which of these variables were associated with having high or low levels of burnout. METHOD: This cross-sectional study assessed 506 family physicians recruited from the Spanish Society of Family Physicians and randomly selected from Primary Health Care Centers. The subgrouping of family physicians based on their burnout scores was assessed by cluster analysis. Variables showing statistically significant differences between clusters and significance below 0.25 in univariate logistic regressions were assessed by multivariate logistic regression analysis. RESULTS: Family physicians reporting higher burnout scores (25%) felt that fibromyalgia patients on sick leave increased their workload, reported no support from nurses in the treatment of fibromyalgia patients, and had a more negative impression of fibromyalgia patients. CONCLUSIONS: One-quarter of family physicians reported feeling exhausted, detached from fibromyalgia patients, or less professionally accomplished. Several personal characteristics and contextual variables increased burnout. Several interventions to modify these variables and, thus, protect family physicians treating fibromyalgia from burnout are suggested.

The Discriminatory Ability of the Fibromyalgia Rapid Screening Tool (FiRST): An International Study in Spain and Four Latin American Countries.

OBJECTIVE: To assess the transcultural equivalency of the Spanish version of the Fibromyalgia Rapid Screening Tool (FiRST) and its discriminatory ability in different Latin American samples. DESIGN: Validation study. SETTING: Departments of Rheumatology in general hospitals and private centers; fibromyalgia unit in a university hospital. SUBJECTS: 350 chronic pain patients from Spain, Argentina, Mexico, Peru, and Ecuador. METHODS: The cultural relevance of the Spanish version of the FiRST was evaluated. The ability of the FiRST as a screening tool for fibromyalgia was assessed by logistic regression analysis. To determine the degree to which potential confounders, such as differences in demographics, pain, affective distress, catastrophizing, and disability, might affect the discriminatory ability, the tool was reassessed by hierarchical multivariate logistic regression. RESULTS: Slightly different versions of the FiRST were recommended for use in each Latin American subsample. The FiRST showed acceptable criterion validity and was able to discriminate between fibromyalgia and non-fibromyalgia patients even after controlling for the effect of potential confounders. However, low specificities were observed in samples from Spain and Mexico. CONCLUSIONS: The Spanish version of the FiRST may be used as a screening tool for fibromyalgia in several Latin American subsamples, even in those patients with high scores on potential confounders. In Spain and Mexico, the low specificity of the FiRST suggests, however, that it would be best used to support a suspected diagnosis of fibromyalgia, rather than to exclude the diagnosis.

Work, family and social environment in patients with Fibromyalgia in Spain: an epidemiological study: EPIFFAC study.

BACKGROUND: Fibromyalgia (FM) is a condition characterized by widespread pain, estimated to affect 2.4% of the Spanish population. Nowadays, there are no consistent epidemiological studies on the actual impact of the disease on work and family of these patients in a representative manner; therefore, the purpose of the study is to analyze the impact on family, employment and social environment in a representative sample of patients with FM attending Primary Public Care Centers in Spain. METHODS: We carried out an epidemiological study, with a probability sampling procedure, stratified, relative to the municipality size and the number of health centres, seeking territorial representation. The survey was conducted using a self-administered structured questionnaire. RESULTS: A sample of 325 patients with FM was studied in 35 Primary Health Care Centers (PHCCs). The sample is composed of 96.6% of women, 51.9 (8) years of mean (standard deviation- sd) age. Ninety-three percent of the patients have worked throughout their life. Mean (sd) age onset of symptoms was 37 (11) years and diagnosis of FM was established 6.6 (8) years later. Family Environment: Fifty-nine percent of patients have difficulties with their partner. Forty-four percent of the patients report to be fairly or totally dependent on a family member in household chores. The household income decreased a mean (sd) of 708 (504) Euros/month in 65% of the patients. In 81% of the patients, there was an increase in extra expenses related to the disease with a mean (sd) of 230 (192) Euros/month. Working environment: At the moment of the study, 45% of the patients had work activity (34% were working and 11% were at sick leave), 13% were unemployed seeking job and 42% were not in the labor force. Twenty-three percent of patients had some degree of permanent work disability pension. Social Environment: The degree of satisfaction with health care professionals was low and twenty-six percent of the patients were members of specific patients associations. CONCLUSIONS: This study finds that people with FM who visit PHCCs of Spain experience a high impact on families and employment with heavy loss of ability to work.
