Impact of Combined Phototherapy and Melanocyte Transplantation on Indicators of Vitiligo Activity.

To investigate the effect of phototherapy combined with melanocyte transplantation on the activity index of vitiligo. One hundred twenty patients with stable vitiligo were selected and divided into 2 groups: phototherapy group (n = 60) and phototherapy combined with melanocyte therapy group (n = 60). Patients' vitiligo activity scores before and 6 months after treatment, patients' skin pigmentation responses 6 months after treatment, and patients' new Koebner cases 6 months after treatment were compared. The expression of tyrosinase and Melan-A in the skin samples was analyzed by immunohistochemistry. The effect of skin surface repigmentation in the observation group was better than that in the control group (p < .05). The expression of tyrosinase and Melan-A in the observation group was higher than that in the control group (p < .05), indicating that the combined treatment could enhance the function of melanocytes. After 6 months of treatment, the incidence of the Koebner phenomenon in the observation group was lower than that in the control group (p < .05). The combination of phototherapy and melanocyte transplantation can obviously improve the activity index of vitiligo, slow down the spread of white spots, reduce the formation of new white spots, and reduce the occurrence of the Koebner phenomenon.

Comparison of short-term clinical results between modified kinematically-aligned and guided motion bicruciate stabilized total knee arthroplasty

BackgroundBoth kinematically-aligned (KA) total knee arthroplasty (TKA) and bicruciate stabilized (BCS) TKA aim to reproduce the physiological knee kinematics. In this study, we compared the femoro-tibial component rotational mismatch between patients who underwent modified KA-TKA and those who received guided-motion BCS-TKA, and its influence on the clinical outcomes.MethodsIn this retrospective study, 77 consecutive patients were included and divided into two groups: subjects who underwent modified KA-TKA with Persona (KA Group; n = 42) and those who received BCS-TKA with JOURNEY II (BCS group; n = 35). Range of motion, the 2011 Knee Society Score (KSS), the rotational alignment of the femoral and tibial components, and the correlations between the rotational mismatch and the 2011 KSS subscales were examined.ResultsThe postoperative objective knee indicators (P = 0.0157), patient satisfaction (P = 0.0039) and functional activity scores (P = 0.0013) in the KA group were significantly superior to those in the BCS group 1 year postoperatively. There was no significant difference between the two groups observed in the rotational mismatch. In the BCS group, significant negative correlations were identified between the rotational mismatch and objective indicators, patient satisfaction, and functional activity scores but not in the KA group.ConclusionsThe short-term clinical results following KA-TKA showed superior objective knee indicators, patient satisfaction and functional activity scores. A negative correlation was observed between component rotational mismatch and the 2011 KSS subscales in the BCS group, compared to no relationship found between the two in the KA group. These findings suggested that KA-TKA has a relatively higher tolerance for rotational mismatch than BCS-TKA.

Impact of Race on the Efficacy and Safety of Tofacitinib in Rheumatoid Arthritis: Post Hoc Analysis of Pooled Clinical Trials.

Racial disparities in disease activity, clinical outcomes, and treatment survival persist despite advancements in rheumatoid arthritis (RA) therapies and clinical management. In this post hoc analysis of pooled data from the tofacitinib global clinical program, we evaluated the impact of race on the efficacy and safety of tofacitinib in patients with RA. Data were pooled from 15 phase 2-3b/4 studies of patients with RA treated with tofacitinib 5 or 10mg twice daily, adalimumab, or placebo. Outcomes were stratified by self-reported patient race (White/Black/Asian/Other). Efficacy outcomes to month 12 included: American College of Rheumatology (ACR)20/50/70 responses, Clinical Disease Activity Index (CDAI)/Disease Activity Score in 28 joints, erythrocyte sedimentation rate [DAS28-4(ESR)] low disease activity (LDA) rates, least squares (LS) mean change from baseline (∆) in CDAI, DAS28-4 (ESR), Health Assessment Questionnaire-Disability Index (HAQ-DI), and Pain [Visual Analog Scale (VAS)]. Odds ratios (ORs; 95% CI) versus placebo, and placebo-adjusted ∆LS means were calculated for active treatments using logistic regression model and mixed-effect model of repeated measurements, respectively. Safety outcomes were assessed throughout. A total of 6355 patients were included (White, 4145; Black, 213; Asian, 1348; Other, 649). For tofacitinib-treated patients, ORs for ACR20/50/70 responses and CDAI/DAS28-4(ESR) LDA rates through month 3 were generally numerically higher for White/Asian/Other versus Black patients. Across active treatments, trends toward higher placebo-adjusted improvements from baseline in CDAI, DAS28-4 (ESR), HAQ-DI, and Pain (VAS) were observed in Asian/Other versus White/Black patients. Numerically higher placebo responses in Black versus White/Asian/Other patients were generally observed across outcomes through month 12. Safety outcomes were mostly similar across treatment/racial groups. In patients with RA, tofacitinib was efficacious across racial groups with similar safety outcomes; observed racial differences potentially reflect patient demographics or regional practice disparities.

Filling the "GAP" in Real-World Assessment of Psoriatic Arthritis Disease Activity: Performance Characteristics of a Global/Pain Composite Endpoint.

Some retrospective data sources, such as electronic health records in the USA, report composite outcome measures not fully validated in psoriatic arthritis (PsA). However, they often contain global assessments, such as a Physician Global Assessment (PhGA) and Patient Global Assessment (PatGA), along with patient-reported pain scores, which individually are considered validated in PsA. This research described the performance characteristics of a 3-item global assessment and pain (GAP) composite endpoint using data from the ixekizumab phase3 PsA clinical trial program. Discrimination of GAP was assessed by comparing placebo to active treatment arms. The magnitude of treatment effect and responsiveness were compared to Disease Activity Index for PsA (DAPSA), clinical DAPSA, DAPSA28, and Psoriatic Arthritis Disease Activity Score (PASDAS) using effect size (ES) and standardized response mean (SRM), respectively. Construct validity was evaluated through correlation among the composite endpoints, and with other physician- and patient-reported outcomes. Change in GAP was compared in patients who reached low disease activity (LDA) levels based on DAPSA, cDAPSA, and PASDAS vs those who did not. GAP discriminated between active treatment and placebo with statistically significant separation as early as week1. The largest ES/SRM was seen with GAP (2.29/1.74) and PASDAS (2.47/1.68). GAP had the strongest correlation with PASDAS (0.81-0.92) and showed moderate correlations with patient-assessed physical function, low correlations with physician-assessed skin and nail psoriasis, and low to moderate correlation with physician-assessed enthesitis. A significantly greater improvement in GAP was seen in the groups achieving LDA states compared to those not (p < 0.001). The GAP composite, an abbreviated endpoint comprising measures common in electronic health records, has promising performance characteristics and could be used to address important clinical questions regarding outcomes and impact of PsA in existing datasets.

Sleep quality in patients with chronic spontaneous urticaria and relation with Orexin-A, leptin, and ghrelin.

Background: Sleep can be affected in patients with chronic spontaneous urticaria (CSU). The mechanisms of sleep regulation remain poorly understood. Orexin-A, a neuroexcitatory peptide, plays a role in coordinating sleep-wake states. Ghrelin and leptin are involved in sleep regulation through the orexin system. Objective: The effects of orexin-A, ghrelin, and leptin on sleep quality in patients with CSU have not been investigated. We aimed to determine the effects of CSU on sleep quality and the association between serum orexin-A, ghrelin, and leptin levels, and sleep quality in patients with CSU. Methods: Thirty-three patients with CSU and 34 sex- and age-matched controls were included in the study. Serum orexin-A, leptin, and ghrelin levels, and the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) scores were measured in patients with CSU and in the controls; also used were the chronic urticaria quality-of-life questionnaire score and the urticaria activity score used for 7 consecutive days. Results: Median (minimum-maximum) orexin-A, leptin, and ghrelin levels in patients were 385 pg/mL (90-495 pg/mL), 3.1 ng/mL (0-21.2 ng/mL), and 701.8 pg/mL (101.9-827.7 pg/mL), respectively. Median serum orexin-A and leptin levels were higher in the patients compared with the controls (p < 0.001 and p = 0.012, respectively), whereas the median serum ghrelin levels were similar to the controls (p = 0.616). The serum orexin-A level was positively correlated with ghrelin (r = 0.298, p = 0.014), PSQI sleep quality (r = 0.356, p = 0.003), and ESS (r = 0.357, p = 0.003). Conclusion: Serum orexin-A is associated with sleep quality in patients with CSU. Further studies are needed to elucidate the role of ghrelin and leptin on sleep quality in patients with CSU.

Role of Serum IFN-γ and IL-10 as Predictive Biomarkers of Vitiligo Disease Activity: A Case-Control Study

Abstract Background and Objectives: IFNγ is a pleiotropic cytokine and through the regulation of immunologically relevant genes, they coordinate a wide range of cellular programs.[1] As a potent pro-inflammatory cytokine, it plays a pivotal role to induce depigmentation in vitiligo. In this study, we aim to assess the role of IFNγ in the activity, duration and extent of the disease and the antagonistic action of IL-10 is also assessed in vitiligo. Materials and Methods: A case-control study was conducted with 100 study participants with 50 cases clinically diagnosed as Vitiligo and 50 controls. All patients underwent complete evaluation with detailed demographic parameters, history and physical examination. The severity of the disease was assessed clinically by Vitiligo Area Scoring Index (VASI) and Vitiligo Disease Activity Score (VIDA). And blood investigations done were IFN-γ and IL-10. Results: We observed significantly higher levels of serum IFNγ levels in the patient group when compared with those of the normal controls (p=0.002) and showed a positive correlation with the activity and severity of the disease with a significant VASI (p=0.05) and VIDA score (p=&lt;0.001). The mean serum IL-10 (p&lt;0.001) in patients with vitiligo was significantly lower than that in the control group. Conclusion: This study showed significantly high serum levels of IFN-γ and correspondingly low levels of IL-10. New strategies, such as the combination of IFNγ blockade with inhibition of other signalling pathways, may further improve IFNγ targeted immunotherapy of the disease.

Assessment of clinical phenotypic characteristics of patients with angioedema without wheals in a turkish population.

Background: Angioedema (AE) is defined as localized, self-limited swelling of subcutaneous tissues and mucosa. Objective: The aim of this study was to compare the phenotypic characteristics of patients with AE without wheals. Methods: This prospective study included adult patients with recurrent AE without wheals. Demographic and laboratory data of the patients were recorded in the patient file when they presented to the outpatient clinic between August 2018 and August 2020. The patients were contacted by phone to evaluate whether their AE had gone into remission between October 2023 and January 2024. The phenotypic characteristics of AE subtypes were compared. Results: The study included a total of 143 patients. The average age, age of onset of AE, rates of diabetes mellitus, hypertension and coronary artery disease were higher in the patients with angiotensin-converting enzyme inhibitor (ACEI) use related acquired AE (AAE) (AAE-ACEI). The rates of allergic rhinitis, drug allergy, atopy, and aeroallergen sensitivity, and the median total immunoglobulin E level were higher in patients with idiopathic histaminergic AAE (AAE-IH). The rate of face and/or perioral AE attacks was higher in the patients with AAE-ACEI, AAE-IH, and idiopathic non-histaminergic AAE. The rate of AE attacks in limbs, abdominal, genital and other parts of the body was higher in patients with hereditary AE (HAE). The baseline AE activity score was lower in the patients with AAE-IH and higher in the patients with HAE. In long-term follow-up, the remission rate of AE attacks was significant higher in patients with AAE-ACEI and AAE-IH. Conclusion: The phenotypic characteristic features of Turkish patients with AE without wheals may vary, depending on the underlying AE pathogenesis. C1 inhibitor level and function, complement C4 and C1q, and genetic tests contributed to the diagnosis; other laboratory tests did not contribute to the diagnosis.

Results of a 12-Week Open-Label, Non-Interventional Study of the Efficacy and Safety of Olokizumab Therapy in Patients with Rheumatoid Arthritis after Switching from Anti-B-Cell Therapy during the SARS-CoV-2 Pandemic.

The purpose of the study was to evaluate the efficacy and safety of the drug Artlegia® (olokizumab), solution for subcutaneous injection, 160 mg/ml-0.4 ml, manufactured by R-Pharm JSC, Russia) for the treatment of patients with rheumatoid arthritis in real clinical practice after switching with rituximab during the COVID-19 pandemic. The study included 14 patients with a confirmed diagnosis of rheumatoid arthritis (RA), who were previously on rituximab therapy at a dose of 1000-500 mg twice with an interval of 2 weeks, who received at least one course of therapy with this drug. As RA worsened, patients were switched to olokizumab against the background of standard DMARDs. On weeks 0, 4, 8, and 12 after the switch, the severity of pain was assessed on the VAS scale, the number of tender and swollen joints (TJC28 and SJC28), the level of acute-phase inflammation markers, the DAS28 (disease activity score), ESR, CRP, CDAI (clinical activity index), and the functional state index HAQ (Health Assessment Questionnaire) were determined, as well as the safety profile of therapy was assessed. Data analysis was performed using median values (Me) were used for data analysis. A significant decrease in TJC28 was detected after 8 and 12 weeks of treatment with olokizumab (Artlegia®) (Me baseline = 10, Me 8 weeks = 4, Me 12 weeks = 4, p < 0.05) and a decrease in TSC28 was detected after 4, 8, and 12 weeks of treatment (Me baseline = 9, Me 4 weeks = 3.5, Me 8 weeks = 2.5, Me 12 weeks = 2.0, p < 0.05). Laboratory markers of inflammation showed a decrease in CRP and ESR levels after 4 weeks of treatment (CRP: Me4 weeks = 21, Me4 weeks = 1, p < 0.05, ESR: Mesno = 31, Me4 weeks = 7, p < 0.05). Positive dynamics persisted on 8 and 12 weeks (CRP: Me 8 weeks = 1, Me 12 weeks = 0; ESR: Me 8 weeks = 4, Me 12 weeks = 5). The level of CRP by week 4 became within the normal range, regardless of the initial values. All activity indices improved from week 4 in each evaluation period compared to baseline: DAS28-ESR: Me baseline = 5.52, Me 4 weeks = 3.59, Me 8 weeks = 3.33, Me 12 weeks = 3.22, p < 0.05; DAS28CRP: Me baseline = 5.39, Me 4 weeks = 3.71, Me 8 weeks = 3.35, Me 12 weeks = 3.45, p < 0.05; CDAI: Me baseline = 28.5, Me 4 weeks = 18.0, Me 8 weeks = 16.5, Me 12 weeks = 16.0, p < 0.05. All patients showed a reduction in pain (VAS scale) by week 8. The functional status of patients, according to the HAQ index, showed a significant decrease only by week 12 of the study: Me baseline = 1.62, Me 12 weeks = 1.31, p < 0.05. The study found that switching from rituximab to olokizumab was effective and safe during the COVID-19 pandemic.

Nonoperative Versus Operative Treatment of Z-Type Comminuted Clavicle Fractures in Adolescents: A Prospective Substratified Cohort Analysis.

To compare the clinical, radiographic, and patient-reported outcomes of nonoperative and operative treatment of adolescents with comminuted "Z-type" midshaft clavicle fractures. Prospective observational cohort. Eight tertiary care pediatric centers. Patients aged 10-18 years who were treated either operatively or nonoperatively for a diaphyseal clavicle fracture between 2013 and 2017 were screened/enrolled at the time of injury. The current subcohort analysis was derived from a larger adolescent clavicle study population of 907 patients. Complications and validated patient-reported outcome measures (PROs):(ASES, QuickDASH, Marx Shoulder Activity Score, EQ-5D, EQ-VAS, and patient satisfaction score) were compared between operative and nonoperative cohorts. Eighty-one patients (69 male [85.2%], 12 female; average age 15 years [11.1-18.7]; 78 with sports participation [96.2%]) were followed through bony healing and return to sports, while 59 patients (73%) completed 2-year follow-up with PROs, 26 of whom were treated nonoperatively and 33 treated operatively. All demographic and fracture characteristics were similar (P > 0.05) between the 2-year follow-up cohorts except for fracture shortening, which was greater in the operative cohort (23 vs. 29 mm, P = 0.01). After controlling for this potential confounder through both regression and propensity matched subgroup analysis, nonoperative versus operative cohorts showed no difference in rates of nonunion (0%), delayed union (0% vs. 2.3%, P = 1.0), symptomatic malunion (2.7% vs. 0%, P = 0.4), refracture (2.7% vs. 2.2%, P = 1.0), unexpected subsequent surgery (5.4% vs. 11.4%, P = 0.45), or clinically significant complications (5.4% vs. 16%, P = 0.17). There were no differences in any PROs between cohorts, both before and after controlling for the difference in fracture shortening (all P-values >0.05). In this prospective comparison of complications and 2-year PROs in adolescents with comminuted Z-type clavicle fractures, nonoperative and operative treatment yielded similar outcomes. Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Both Hamstring and Quadriceps tendon autografts offer similar functional outcomes after arthroscopic ACL reconstruction in patients over 50 years of age

PurposeThe purpose of this study was to compare the outcomes of hamstring tendon (HT) and quadriceps tendon (QT) autografts for anterior cruciate ligament (ACL) reconstruction in patients older than 50 years in terms of patient-reported functional outcomes, graft failure rates, complications, return to sports activity and the preference for sports. MethodsBetween 2010 and 2022, prospectively collected data were obtained from an institutional database. Patients older than 50 years with primary arthroscopic ACL reconstruction using either HT or QT autograft and a minimum of 2 years of follow-up were included. Patients with concomitant meniscus, cartilage and MCL injury were also included. Patients undergoing a revision ACL reconstruction or undergoing a primary ACL reconstruction using a graft other than HT or QT autograft, and patients with a contralateral knee injury or ipsilateral osteoarthritis (Ahlback stage 2 or higher) were excluded. Patients were evaluated for pre-injury and 2-year follow-up Lysholm knee score, Tegner activity level, Visual Analog Scale (VAS) for pain, graft failure, quadriceps tendon rupture, and return to sport. Mann-Whitney test was used for unpaired samples, whereas the Friedman test was used for analyzing variables over time. The chi-square statistic test was used to determine differences in categorical data between groups ResultsThe number of patients in the QT and HT groups was 85 and 143 respectively. The mean age was 54.4 [50-65] and 56.4 [50-65] for the QT and HT groups respectively, 49% and 51% were males in the QT and HT groups respectively. The two groups did not differ significantly in terms of age, gender, time from injury to surgery and concomitant injuries. No significant differences were found in the pre-injury patient-reported outcome scores (PROMs) as Lysholm, Tegner activity level and VAS for pain between the two groups (p>0.05). At the 2-year follow-up, Lysholm knee score, Tegner activity level and VAS for pain improved to pre-injury level and no significant difference was noted between pre-injury and 2-year follow-up functional scores between the two groups (p>0.05).Furthermore, at the 2-year follow-up, Lysholm score, and VAS didn't show significant differences between QT and HT groups. (p=.390; p= .131). Similarly, no differences have been reported in Tegner activity level scores between HT and QT groups at 2 years of follow-up. No significant differences in terms of minimal clinically important difference (MCID) have been detected between the two groups for Lysholm and Tegner activity scores (p = 0.410 and p = 0.420 for Lysholm score and Tegner activity level score respectively).The two groups did not differ in terms of patient’s percentage of sports participation at baseline, and 2 years of follow-up (p>0.05). A significant decrease (p=0.01) in skiing/snowboarding was reported in the HT group at a 2-year follow-up compared to baseline [116 (81%) vs 98 (69%)]. No case of graft failures and quadriceps tendon rupture was reported in either of the groups. ConclusionArthroscopic ACL reconstruction by using HT or QT autograft in athletically active older than 50 years patients provide satisfactory patient-reported functional outcomes and allows recovery of the pre-injury level of activity.

Perturbation-based Balance Training in Adults Aged Above 55 Years with Chronic Low Back Pain: A Comparison of Effects of Water versus Land Medium - A Preliminary Randomized Trial.

'Rapid balance reaction' or 'perturbation' training is an emerging paradigm in elderly back pain rehabilitation due to its connection to postural stability. This study aimed to inform the feasibility and practicality of perturbation-based balance training (PBT) using a stratification approach and to determine the effectiveness of land versus water-based PBT in elderly individuals with chronic low back pain (CLBP). Elderly CLBP participants (n=24) received exercise interventions as per treatmentbased classification (TBC) and were randomly allotted into water-based perturbation exercises (WBPE, Mean age=63.0±2.6years, n=12) and land-based perturbation exercise group (LBPE, 62.3±2.6 years, n=12). Pain intensity, disability, scores of fear-avoidance beliefs, fall efficacy, and rate of perceived exertion (RPE) were assessed before and at the end of 6 weeks. WBPE group reported a significant reduction in pain score (median difference(MD)):2, p<0.03), fear avoidance behaviour for work (MD:9, p<0.01) and fear avoidance behaviour for physical activity (MD:10, p< 0.05), improved straight leg raise right (SLR) (MD:37.5°, p<0.05), and improved modified fall efficacy scores (MFES, MD:25, p<0.05) compared to the LBPE group at post-intervention. Within-group analysis in both groups revealed significant improvement in clinical outcomes except for fear-avoidance beliefs related to physical activity in the LBPE group. Subgroup analysis revealed that the high BMI elderly CLBP group of LBPE had significant improvements similar to the WBPE group except for scores of FABQ physical activity scores and SLR. Possible key factors for future research are discussed in the realms of perturbation exercise in the elderly with CLBP.

Effects of serum inflammatory factors, health index and disease activity scores on ankylosing spondylitis patients with sleep disorder.

Patients with ankylosing spondylitis (AS) frequently suffer from comorbid sleep disorders, exacerbating the burden of the disease and affecting their quality of life. To investigate the clinical significance of serum inflammatory factors, health index and disease activity scores in patients with AS complicated by sleep disorders. A total of 106 AS patients with comorbid sleep disorders were included in the study. The patients were grouped into the desirable and undesirable prognosis groups in accordance with their clinical outcomes. The serum levels of inflammatory factors, including C-reactive protein, erythrocyte sedimentation rate, interleukin (IL)-6, tumour necrosis factor-α and IL-1β, were measured. Disease activity scores, such as the Bath AS functional index, Bath AS disease activity index, Bath AS metrology index and AS disease activity score, were assessed. The health index was obtained through the Short Form-36 questionnaire. The study found significant associations amongst serum inflammatory factors, health index and disease activity scores in AS patients with comorbid sleep disorders. Positive correlations were found between serum inflammatory factors and disease activity scores, indicating the influence of heightened systemic inflammation on disease severity and functional impairment. Conversely, negative correlations were found between disease activity scores and health index parameters, highlighting the effect of disease activity on various aspects of health-related quality of life. Logistic regression analysis further confirmed the predictive value of these factors on patient outcomes, underscoring their potential utility in risk assessment and prognostication. The findings demonstrate the intricate interplay amongst disease activity, systemic inflammation and patient-reported health outcomes in AS patients complicated by sleep disorders. The results emphasise the need for comprehensive care strategies that address the diverse needs and challenges faced by these patients and underscore the potential relevance of serum inflammatory factors, health index and disease activity scores as prognostic markers in this patient population.

Hearing loss and its association with the proteome of perilymph, cerebrospinal fluid, and tumor tissue in patients with vestibular schwannoma

This study examined the association between hearing loss in sporadic vestibular schwannoma patients and the proteome of perilymph (PL), cerebrospinal fluid (CSF), and vestibular schwannoma. Intraoperative sampling of PL and of CSF, and biopsy of vestibular schwannoma tissue, was performed in 32, 32, and 20 patients with vestibular schwannoma, respectively. Perilymph and CSF in three patients with meningioma and normal hearing were also sampled. The proteomes were identified by liquid chromatography coupled to high-resolution tandem mass spectrometry. Preoperative hearing function of the patients was evaluated with pure tone audiometry, with mean values at frequencies of 500, 1000, 2000, and 4000 Hz (PTA4) in the tumor-affected ear used to delineate three hearing groups. Analysis of the PL samples revealed significant upregulation of complement factor H-related protein 2 (CFHR2) in patients with severe to profound hearing loss after false discovery rate correction. Pathway analysis of biofunctions revealed higher activation scores in the severe/profound hearing loss group of leukocyte migration, viral infection, and migration of cells in PL. Upregulation of CFHR2 and activation of these pathways indicate chronic inflammation in the cochlea of vestibular schwannoma patients with severe to profound hearing loss compared with patients with normal hearing or mild hearing loss.

Semi-rational design of nitroarene dioxygenase for catalytic ability toward 2,4-dichloronitrobenzene.

Rieske non-heme dioxygenase family enzymes play an important role in the aerobic biodegradation of nitroaromatic pollutants, but no active dioxygenases are available in nature for initial reactions in the degradation of many refractory pollutants like 2,4-dichloronitrobenzene (24DCNB). Here, we report the engineering of hotspots in 2,3-dichloronitrobenzene dioxygenase from Diaphorobacter sp. strain JS3051, achieved through molecular dynamic simulation analysis and site-directed mutagenesis, with the aim of enhancing its catalytic activity toward 24DCNB. The computationally predicted activity scores were largely consistent with the detected activities in wet experiments. Among them, the two most beneficial mutations (E204M and M248I) were obtained, and the combined mutant reached up to a 62-fold increase in activity toward 24DCNB, generating a single product, 3,5-dichlorocatechol, which is a naturally occurring compound. In silico analysis confirmed that residue 204 affected the substrate preference for meta-substituted nitroarenes, while residue 248 may influence substrate preference by interaction with residue 295. Overall, this study provides a framework for manipulating nitroarene dioxygenases using computational methods to address various nitroarene contamination problems.IMPORTANCEAs a result of human activities, various nitroaromatic pollutants continue to enter the biosphere with poor degradability, and dioxygenation is an important kickoff step to remove toxic nitro-groups and convert them into degradable products. The biodegradation of many nitroarenes has been reported over the decades; however, many others still lack corresponding enzymes to initiate their degradation. Although rieske non-heme dioxygenase family enzymes play extraordinarily important roles in the aerobic biodegradation of various nitroaromatic pollutants, prediction of their substrate specificity is difficult. This work greatly improved the catalytic activity of dioxygenase against 2,4-dichloronitrobenzene by computer-aided semi-rational design, paving a new way for the evolution strategy of nitroarene dioxygenase. This study highlights the potential for using enzyme structure-function information with computational pre-screening methods to rapidly tailor the catalytic functions of enzymes toward poorly biodegradable contaminants.

Trends in cardiovascular health among US adults by glycemic status based on Life's Essential 8

ObjectiveWe aimed to assess the secular trends in cardiovascular health (CVH) among U.S. adults with different glycemic statuses based on the Life's Essential 8 (LE8). MethodsThis cross-sectional study used nationally representative data from 6 cycles of the National Health and Nutrition Examination Surveys between 2007 and 2018. Survey-weighted linear models were used to assess time trends in LE8 scores. Stratified analyses and sensitivity analyses were conducted to validate the stability of the results. ResultsA total of 23,616 participants were included in this study. From 2007 to 2018, there was no significant improvement in overall CVH and the proportion of ideal CVH among participants with diabetes and prediabetes. We observed an opposite trend between health behavior and health factors in the diabetes group, mainly in increasing physical activity scores and sleep scores (P for trend<0.001), and declining BMI scores [difference, −6.81 (95% CI, −12.82 to −0.80)] and blood glucose scores [difference, −6.41 (95% CI, −9.86 to −2.96)]. Dietary health remained at a consistently low level among participants with different glycemic status. The blood lipid scores in the prediabetes group improved but were still at a lower level than other groups. Education/income differences persist in the CVH of participants with diabetes or prediabetes, especially in health behavior factors. Sensitivity analyses of the absolute difference and change in proportion showed a consistent trend. ConclusionsTrends in CVH among participants with diabetes or prediabetes were suboptimal from 2007 to 2018, with persistent education/income disparities.

Defining criteria for disease activity states in systemic juvenile idiopathic arthritis based on the systemic Juvenile Arthritis Disease Activity Score.

To develop and validate cutoff values in the systemic Juvenile Arthritis Disease Activity Score 10 (sJADAS10) that distinguish the states of inactive disease (ID), minimal disease activity (MiDA), moderate disease activity (MoDA), and high disease activity (HDA) in children with systemic juvenile idiopathic arthritis (sJIA), based on subjective disease state assessment by the treating pediatric rheumatologist. The cutoffs definition cohort was composed of 400 patients enrolled at 30 pediatric rheumatology centers in 11 countries. Using the subjective physician rating as an external criterion, 6 methods were applied to identify the cutoffs: mapping, calculation of percentiles of cumulative score distribution, Youden index, 90% specificity, maximum agreement, and ROC curve analysis. Sixty percent of the patients were assigned to the definition cohort and 40% to the validation cohort. Cutoff validation was conducted by assessing discriminative ability. The sJADAS10 cutoffs that separated ID from MiDA, MiDA from MoDA, and MoDA from HDA were ≤ 2.9, ≤ 10, and > 20.6. The cutoffs discriminated strongly among different levels of pain, between patients with or without morning stiffness, and between patients whose parents judged their disease status as remission or persistent activity/flare or were satisfied or not satisfied with current illness outcome. The sJADAS cutoffs revealed good metrologic properties in both definition and validation cohorts, and are therefore suitable for use in clinical trials and routine practice.

Correlation of DAS 28 Score and Treatment Compliance with Depression and Anxiety in Rheumatoid Arthritis

Background: Rheumatoid arthritis (RA) is a chronic systemic autoimmune disorder characterized by synovial inflammation, joint destruction, and significant disability. Psychological factors, particularly depression and anxiety, are prevalent among RA patients and can impact disease management and treatment adherence. Understanding the relationship between disease activity, treatment compliance, and mental health is essential for comprehensive RA management. Objective: To investigate the correlation between Disease Activity Score 28 (DAS28) and treatment compliance with levels of depression and anxiety in patients with rheumatoid arthritis. Methods: This cross-sectional study was conducted at the Department of Rheumatology and Immunology, Sheikh Zayed Hospital, Lahore, over six months. A total of 130 RA patients were enrolled using non-probability convenience sampling. Inclusion criteria were adults aged 18 years and above, diagnosed with RA based on ACR/EULAR criteria, and compliant with medication for at least three months prior to the study. Exclusion criteria included other autoimmune diseases, significant concurrent medical conditions, history of substance abuse, and recent initiation of biologic treatments. Data collection involved demographic details, RA onset and duration, and assessments of depression and anxiety using the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) scales, respectively. RA disease activity was measured using DAS28, and systemic inflammation markers (ESR and CRP) were recorded. Data analysis was performed using SPSS version 25.0, employing descriptive statistics, correlation analysis, and regression analysis to determine the relationships between variables. Results: The study included 59 males (45.4%) and 71 females (54.6%), with a mean age of 49.69 years (SD = 18.82). The mean duration of RA diagnosis was 14.07 years (SD = 8.69). Higher PHQ-9 scores were associated with lower treatment adherence (B = -1.264, p &lt; 0.001), and higher GAD-7 scores also negatively impacted adherence (B = 0.870, p &lt; 0.01). The regression model explained 40.3% of the variance in treatment adherence (R² = 0.403, F(7, 122) = 11.779, p &lt; 0.001). Weak negative correlations were observed between DAS28 ESR and treatment adherence (r = -0.150), indicating that higher disease activity slightly reduced adherence. Conclusion: The study highlighted the significant role of mental health in the management of RA. Depression and anxiety were found to be major barriers to treatment adherence, underscoring the need for integrating psychological care into RA management. Addressing mental health issues could enhance treatment adherence and improve overall disease outcomes.
