For this systematic review, a search of the relevant literature was conducted in the EMBASE and PubMed databases. We used the following terms: ‘rheumatoid arthritis’ in conjunction with ‘fatty acid’. The following inclusion criteria had to be satisfied for the studies to be included in the analysis: an RCT/observational/cohort study published in English. A total of seventy-one studies were analysed. The presented systematic review of the available data indicates that increased consumption of omega-3 fatty acids (FAs) may have a beneficial effect on human health by decreasing pain and disease activity in patients with RA. The beneficial effect of unsaturated FA on the clinical parameters of RA was demonstrated in all 71 studies analysed. The content of omega-3 FAs in the diet and the consumption of fish, which are their main source, may contribute to a reduced incidence of RA. FAs are an essential component in the synthesis of eicosanoids that exhibit anti-inflammatory properties. Due to the documented positive influence of unsaturated FAs on treatment outcomes, the use of a diet rich in long-chain unsaturated FAs should be the standard of care, along with pharmacotherapy, in the treatment of RA patients. An important element in the control of the treatment process should be the routine assessment of the quality of life of RA patients.

Background: Sexual health is a major component of human well-being. As repeatedly shown in research, satisfaction with sex life and sexual fulfillment correlate positively with quality of life (QoL) in most of its aspects. It is thus true that a reduced quality of one’s sex life and lack of sexual fulfillment can contribute to poorer QoL overall. The aim of this study is to describe an assessment of sexual dysfunction and factors affecting sexual dysfunctions of patients with rheumatoid arthritis (RA). Material and methods: 171 consecutive RA patients (mean age 48.3 ± 14.6) attending the rheumatology outpatient clinic. Standardized questionnaires used in the study were the sexological questionnaire, WHOQOL-BREF to assess QoL level, Disease Acceptance Scale, and VAS scale to assess pain intensity. Results: The mean duration of the disease in the study group was 13 ± 9 years, mean score of subjective assessment of mobility was 6.2 ± 1.6, and the mean score of the DAS-28 was 4.0 ± 1.9. The study group presented a mean level of disease acceptance (AIS 29.6 ± 11.6). The comparative analysis showed significant differences in reaching orgasm and declared sexual dysfunctions. These problems occurred more often in women than in men (34.2% vs. 18% and 43% vs. 40%, respectively). In univariate analysis, factors correlating positively with the frequency of declaring sexual dysfunction were subjective motor score less < 6 points, AIS < 36 points, WHOQOL-BREF < 59 points, disease activity ≥3.5 points, and VAS > 3. In multivariate logistic regression analysis, independent factors positively correlating with frequency of sexual dysfunction declaration were general QoL (β = 1.255; p = 0.035) and pain limiting social life (β = 1.564; p = 0.030). The absence of comorbidities correlated negatively and reduced the prevalence of sexual dysfunction (β = −1.030; p = 0.043). Patients with reduced QoL and patients with pain limiting social life had 3.5 and 4.8 times higher risk of sexual dysfunction than other patients, respectively. In contrast, those without comorbidities were 2.8 times more likely to be free of sexual dysfunction than those diagnosed with other chronic diseases besides RA. Conclusions: Sexual dysfunction is an emerging problem in both men and women with RA. The absence of comorbidities is an independent determinant of sexual dysfunction, whereas poor QoL and pain limiting social life are independent determinants that exacerbate sexual dysfunction in both genders.

The COVID-19 pandemic represents a global health and social challenge. However, the impact of a SARS-CoV-2 infection itself on mental health and sleep quality remains poorly understood. The purpose of the present uncontrolled prospective observational pilot study was to evaluate the impact of past COVID-19 disease on the incidence of quantitative and qualitative sleep disturbances. A group of 61 subjects (37 female, 24 male) reported sleep disturbances that had lasted for at least one month and had started after recovery from COVID-19. The study used self-reported instruments: the Epworth Sleepiness Scale (ESS) and Insomnia Severity Index (ISI), as well as an objective method—actigraphy—for quantitative analysis of sleep architecture. It was shown that sleep disturbances most commonly started after recovery (68.3%, n = 41) and lasted for more than one month (83.6%, n = 51). ESS scores of 7.8 ± 5.0 points indicate moderate daytime sleepiness, and ISI scores of 16.3 ± 5.8 points denote moderate insomnia. ESS scores were negatively correlated with total time in bed (r = −0.3780, p = 0.003), total sleep time (r = −0.2969, p = 0.020), and wakefulness after sleep onset (r = −0.2654, p = 0.039). In addition, ESS scores were correlated negatively with the respondents’ age (B = −0.17, p = 0.000) and time from COVID-19 onset. A positive correlation was found between wakefulness after sleep onset and ESS scores (B = −0.05, p = 0.039). ISI scores were positively correlated with time in bed (r = 0.3275, p = 0.010). Female gender was found to be a significant predictor of insomnia’s severity (B = 2.159, t = 3.04, p = 0.004). In conclusion, patients with a history of COVID-19 report long-lasting sleep disturbances that do not subside spontaneously. In the patient group studied, moderate levels of daytime sleepiness and insomnia were found. The most frequently reported problems included irregular sleep, frequent awakenings, and difficulty maintaining sleep, while normal sleep duration was preserved. These findings underscore the need for continued attention to the long-term consequences of COVID-19 on sleep health and emphasize the importance of targeted interventions to address these enduring sleep disturbances in affected individuals.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection and a syndrome shaped by pathogen and host factors evolving over time. During sepsis, the absolute number of lymphocytes decreases. CD4+ and CD8+ T cells, B cells, and NK cells are reduced. Lymphocytes are an essential element of the body's defence against pathogens. Interleukin 7 has strong anti-apoptotic properties and induces the proliferation of CD4+ and CD8+ T lymphocytes. IL-15 prompts the generation of mature NK cells in the bone marrow, plays an important role in the generation, cytotoxicity, and survival of CD8+ T lymphocytes, and is essential for the survival of natural killer T (NKT) and intestinal intraepithelial lymphocytes (IELs). The study highlights the importance of monitoring IL-7 levels in patients with sepsis and septic shock, as low levels of this cytokine were associated with an increased risk of mortality. Physicians should consider using IL-7 levels as a biomarker to identify patients who are at higher risk of mortality and may require more aggressive treatment.

Introduction: Patients with rheumatoid arthritis (RA) often experience depression, which has a very negative impact on the assessment of the quality of life (QoL). However, there are not many studies that assess the relationship between depression and QoL in RA patients. The aim of the study was to assess the level of QoL and determine the mutual relationship between anxiety and depression levels and QoL in patients treated for RA. Material and Methods: The study included 101 patients (aged:52.4± 16.97), who met the established criteria for a diagnosis of RA and treatment with a biological agent. Only standardized tools were used to examine the patients: WHO-QoL, HADS and the VAS scale. Results: The mean RA duration in the group studied was 13.54± 9.51 years and the disease activity score was 4.8± 0.8. The mean QoL perception score was 3.48± 0.8. Nearly 40% of the respondents could not clearly determine their QoL, perceiving it as neither poor nor good, and 10% believed their QoL is poor or very poor. The correlation analysis revealed that anxiety is significantly and negatively associated with QoL in the psychological domain (r = − 0.472, p < 0.001) and social domain (r = − 0.298, p = 0.023) and depression is significantly and negatively associated with QoL in the psychological domain (r = − 0.322, p = 0.01) and physical health domain (r = − 0.209, p = 0.04). In the multiple linear regression model, depression was an independent negative predictor affecting the following domains: perception of QoL and perception of health, and physical health. Conclusion: RA patients treated with biologics present a low level of health perception and an average level of QoL perception. Depression and anxiety negatively correlate with QoL domains: the higher the anxiety and depression levels, the poorer the QoL in the psychological and social relationships domains. Depression is an independent determinant of decreased QoL.
