Background: The minimal detectable change (MDC) and the minimal clinically important changes (MCIC) have been explored for nonspecific low back pain patients and are similar across different cultural settings. No data on MDC and MCIC for pain severity are available for neck pain patients. The objectives of this study were to estimate MDC and MCIC for pain severity in subacute and chronic neck pain (NP) patients, to assess if MDC and MCIC values are influenced by baseline values and to explore if they are different in the subset of patients reporting referred pain, and in subacute versus chronic patients.
BackgroundA low CD4/CD8 ratio has been identified in the general population as a hallmark of inmmunosenescence and a surrogate of all-cause mortality. We aimed to investigate in treated HIV-infected individuals the relationship between the CD4/CD8 ratio and serious non-AIDS events.MethodsCase-control study within a prospective hospital-based cohort of HIV-infected subjects during at least one year of ART-mediated viral suppression. Cases were patients with serious non-AIDS events (non-AIDS malignancies, cardiovascular disease, and end-stage kidney disease), and controls individuals who did not developed non-AIDS events during follow-up. Data were analyzed using ROC analysis and multivariate logistic regression. Conditional logistic regression was performed in 200 cases/controls matched by age, sex, nadir CD4 and proximal CD4 counts.ResultsWe analyzed 407 subjects (109 cases, 298 controls). The CD4/CD8 ratio was lower in cases (0.44 vs. 0.70, P<0.0001), with higher discriminatory ability for the detection of non-AIDS events than the CD4 count, CD8 count and nadir CD4. Multivariate analyses (adjusted for age, sex, nadir CD4, proximal CD4 count, year of ART initiation and ART duration) confirmed the independent association of a low CD4/CD8 ratio with the risk of non-AIDS morbidity (per CD4/CD8 ratio quartile decrease, OR, 2.9; 95% CI, 1.3–6.2) and non-AIDS mortality (OR, 2.8; 95% CI, 1.5–5.3).ConclusionsThe CD4/CD8 ratio provides additional information to the CD4 counts and nadir CD4 in treated HIV-infected individuals, since it is independently associated with the risk of non-AIDS-related morbidity and mortality. This association is robust and maintained within different subgroups of patients.
Factors associated with a higher risk vary between LBP and PGP. History of LBP, related or not to previous pregnancy or postpartum, LBP surgery, and anxiety were the factors more strongly associated with pregnancy-related LBP. When these variables are taken into account, obstetrical data from current or previous pregnancies and other variables do not show a significant association with LBP. Stage of pregnancy and depression were associated with PGP.
ObjectiveTo assess the prevalence of burn-out syndrome in healthcare workers working on the front line (FL) in Spain during COVID-19.DesignCross-sectional, online survey-based study.SettingsSampling was performed between 21st April and 3rd May 2020. The survey collected demographic data and questions regarding participants’ working position since pandemic outbreak.ParticipantsSpanish healthcare workers working on the FL or usual ward were eligible. A total of 674 healthcare professionals answered the survey.Main outcomes and measuresBurn-out syndrome was assessed by the Maslach Burnout Inventory-Medical Personnel.ResultsOf the 643 eligible responding participants, 408 (63.5%) were physicians, 172 (26.8%) were nurses and 63 (9.8%) other technical occupations. 377 (58.6%) worked on the FL. Most participants were women (472 (73.4%)), aged 31–40 years (163 (25.3%)) and worked in tertiary hospitals (>600 beds) (260 (40.4%)). Prevalence of burn-out syndrome was 43.4% (95% CI 39.5% to 47.2%), higher in COVID-19 FL workers (49.6%, p<0.001) than in non- COVID-19 FL workers (34.6%, p<0.001). Women felt more burn-out (60.8%, p=0.016), were more afraid of self-infection (61.9%, p=0.021) and of their performance and quality of care provided to the patients (75.8%, p=0.015) than men. More burn-out were those between 20 and 30 years old (65.2%, p=0.026) and those with more than 15 years of experience (53.7%, p=0.035).Multivariable logistic regression analysis revealed that, working on COVID-19 FL (OR 1.93; 95% CI 1.37 to 2.71, p<0.001), being a woman (OR 1.56; 95% CI 1.06 to 2.29, p=0.022), being under 30 years old (OR 1.75; 95% CI 1.06 to 2.89, p=0.028) and being a physician (OR 1.64; 95% CI 1.11 to 2.41, p=0.011) were associated with high risk of burn-out syndrome.ConclusionsThis survey study of healthcare professionals reported high rates of burn-out syndrome. Interventions to promote mental well-being in healthcare workers exposed to COVID-19 need to be immediately implemented.
A controversy exists over whether the outcome of a hepatitis C virus (HCV)-infection-related liver transplant differs based on the calcineurin inhibitor (CNI) used. We have performed a systematic review and a subsequent meta-analysis evaluating tacrolimus (Tac)-based vs. cyclosporine A-based immunosuppression in HCV-infected liver transplant recipients. Searches were conducted to locate randomized controlled trials comparing Tac vs. cyclosporine A. Data on HCV liver transplant recipients were obtained, independently of whether the study was specifically designed for patients with this disease or not. A fixed effects model was used for statistical pooling of the relative risks (RR) for the different outcomes. A total of 5 articles (366 patients) fulfilled the inclusion criteria. Statistically significant differences between Tac-based vs. cyclosporine A-based therapies were not found for mortality (P ϭ 0.11; RR ϭ 0.72; 95% confidence interval [CI], 0.49-1.08), graft survival (P ϭ 0.37; RR ϭ 0.86; 95% CI, 0.61-1.21), biopsy-proven acute rejection (P ϭ 0.65; RR ϭ 0.91; 95% CI, 0.61-1.36), corticoresistant acute rejection (P ϭ 0.26; RR ϭ 2.25; 95% CI, 0.55-9.29), and fibrosing cholestatic hepatitis (P ϭ 0.92; RR ϭ 0.96; 95% CI, 0.41-2.26). In 1 study, no differences were detected regarding severe fibrosis at 1 yr. In conclusion, patient and graft survivals in HCV-positive liver transplant patients are similar independently of the CNI selected as basic immunosuppressant. Unfortunately, data on the severity of recurrence and effect on viremia are scarce. Well-designed randomized prospective studies are needed to determine whether there are differences between the 2 CNIs regarding these specific variables. Liver Transpl 13: 21-29, 2007.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
