35619835 | Treatment of COVID-19 in a Patient With Maple Syrup Urine Disease. | 2022 Apr | Maple syrup urine disease (MSUD) is an inborn error of metabolism caused by a defect in the branched-chain alpha-ketoacid dehydrogenase complex (BCKDC). This leads to the accumulation of the branched-chain amino acids (BCAAs) leucine, isoleucine, and valine, which can cause neurotoxicity. Patients with MSUD are carefully managed from birth with dietary restrictions and can acutely decompensate in the setting of infections or injury. We present the case of a 29-year-old female with a history of MSUD and rheumatoid arthritis on methotrexate and adalimumab who presented to our emergency department with symptoms suggestive of a metabolic crisis including nausea, vomiting, and presyncope. She was diagnosed with coronavirus disease 2019 (COVID-19) and admitted. An initial leucine level was mildly elevated at 253 μmol/L, consistent with her underlying metabolic condition. She was placed on an infusion of normal saline and 10% Dextrose (D10) in addition to a protein-restricted sick-day diet. Remdesivir therapy was initiated due to her immunocompromised status and high risk for decompensation but had to be discontinued due to nausea and vomiting that negatively impacted the patient's oral intake. Her leucine level peaked at 647 μmol/L; however, her neurologic examination remained benign without signs of cerebral edema. With prompt involvement of our metabolic genetics team and initiation of intravenous fluids and the sick-day diet protocol, we avoided a metabolic crisis. The patient was discharged on day 5 of hospitalization with no complications from COVID-19 infection. This case highlights the individualized approach to the treatment of COVID-19 infection in a patient with a metabolic disorder. COVID-19 infection in the setting of MSUD has only been reported in two prior publications, one being a severe metabolic crisis with neurologic involvement. Fortunately, our patient experienced a mild case of COVID-19 without significant respiratory symptoms, and we were able to prevent a metabolic crisis during admission. | |
35599074 | Correction of a Complex Foot Deformity With V and Y Osteotomy and Ilizarov Method. | 2022 Feb 15 | Many authors consider the Ilizarov method as the best choice for correction of complex multiplanar foot deformities. Fifty-one patients, for a total of 55 feet, underwent V or Y osteotomy (respectively 32 and 23), 12 were due to congenital clubfoot outcomes, 11 were from post-traumatic pathologies, 9 from hemimelia, 7 from Charcot-Marie-Tooth, 5 from poliomyelitis, 3 from spina bifida, 2 from myopathy, 2 from poly-epiphyseal dysplasia, 1 from achondroplasia, 1 from arthrogryposis, 1 patient from Charcot's foot and 1 rheumatoid arthritis. All patients were contacted to undergo AOFAS and EQ-5D-5L questionnaire. The mean distraction time was 74.0 days (±25.3) and it was longer for V osteotomy (63.1 ± 21.1 vs 81.8 ± 25.4 days for Y and V respectively, p = .006). The average fixation time was 97.9 days (± 61.2), 90 days in the Y and 103 days in the V osteotomy groups. The mean preoperative foot length was longer in the group of Y osteotomy patients (158.7 ± 21.3 mm vs 133.5 ± 21.6 mm, p < .001). The mean length postoperatively was substantially the same (Y group 164.0 mm vs V group 167.4 mm, p < .562). The V osteotomy produces an elongation ratio of 440% with respect to that produced from the Y osteotomy (ratio length/distraction V/Y 0.44/0.1), with only 19% more in the distraction days. (81.8 V group vs 63.1 Y group). While the V osteotomy allows a lengthening of about 27%, the Y osteotomy, despite having correction potential superimposable to the V osteotomy, minimizes the elongation component. | |
35359378 | Fibroblast Activation Protein Specific Optical Imaging in Non-Small Cell Lung Cancer. | 2022 | Fibroblast activation protein (FAP) is a cell surface propyl-specific serine protease involved in the regulation of extracellular matrix. Whilst expressed at low levels in healthy tissue, upregulation of FAP on fibroblasts can be found in several solid organ malignancies, including non-small cell lung cancer, and chronic inflammatory conditions such as pulmonary fibrosis and rheumatoid arthritis. Their full role remains unclear, but FAP expressing cancer associated fibroblasts (CAFs) have been found to relate to a poor prognosis with worse survival rates in breast, colorectal, pancreatic, and non-small cell lung cancer (NSCLC). Optical imaging using a FAP specific chemical probe, when combined with clinically compatible imaging systems, can provide a readout of FAP activity which could allow disease monitoring, prognostication and potentially stratify therapy. However, to derive a specific signal for FAP any sequence must retain specificity over closely related endopeptidases, such as prolyl endopeptidase (PREP), and be resistant to degradation in areas of active inflammation. We describe the iterative development of a FAP optical reporter sequence which retains FAP specificity, confers resistance to degradation in the presence of activated neutrophil proteases and demonstrates clinical tractability ex vivo in NSCLC samples with an imaging platform. | |
35275333 | The Airway Microbiome-IL-17 Axis: a Critical Regulator of Chronic Inflammatory Disease. | 2022 Mar 11 | The respiratory tract is home to a diverse microbial community whose influence on local and systemic immune responses is only beginning to be appreciated. Increasing reports have linked changes in this microbiome to a range of pulmonary and extrapulmonary disorders, including asthma, chronic obstructive pulmonary disease and rheumatoid arthritis. Central to many of these findings is the role of IL-17-type immunity as an important driver of inflammation. Despite the crucial role played by IL-17-mediated immune responses in protection against infection, overt Th17 cell responses have been implicated in the pathogenesis of several chronic inflammatory diseases. However, our knowledge of the influence of bacteria that commonly colonise the respiratory tract on IL-17-driven inflammatory responses remains sparse. In this article, we review the current knowledge on the role of specific members of the airway microbiota in the modulation of IL-17-type immunity and discuss how this line of research may support the testing of susceptible individuals and targeting of inflammation at its earliest stages in the hope of preventing the development of chronic disease. | |
35185060 | Anti-GPIHBP1 Antibody-Positive Autoimmune Hyperchylomicronemia and Immune Thrombocytopenia | 2022 Feb 18 | Primary hyperchylomicronemia is characterized by marked hypertriglyceridemia exceeding 1,000 mg/dL. It is caused by dysfunctional mutations in specific genes, namely those for lipoprotein lipase (LPL), glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1 (GPIHBP1), apolipoprotein C2 (ApoC-II), lipase maturation factor 1 (LMF1), or apolipoprotein A5 (ApoA-V). Importantly, antibodies against LPL or GPIHBP1 have also been reported to induce autoimmune hyperchylomicronemia.The patient was a 46-year-old man diagnosed with immune thrombocytopenia (ITP) at 41 years. At the time, he was administered prednisolone (PSL) and eltrombopag, a thrombopoietin receptor agonist. At 44 years, he suffered from acute myocardial infarction, and PSL was discontinued to avoid enhancing atherogenic risks. He was maintained on eltrombopag monotherapy. After discontinuing PSL, marked hypertriglyceridemia (>3,000 mg/dL) was observed, which did not improve even after a few years of pemafibrate therapy. Upon referral to our clinic, the triglyceride (TG) level was 2,251 mg/dL, ApoC-II was 19.8 mg/dL, LPL was 11.1 ng/mL (0.02-1.5 ng/mL), GPIHBP1 was 47.7 pg/mL (740.0-1,014.0 pg/mL), and anti-GPIHBP1 antibody was detected. The patient was diagnosed to have anti-GPIHBP1 antibody-positive autoimmune hyperchylomicronemia. He was administered PSL 15 mg/day, and TG levels were controlled at approximately 200 mg/dL.Recent studies have reported that patients with anti-GPIHBP1 antibody-induced autoimmune hyperchylomicronemia had concomitant rheumatoid arthritis, systemic lupus erythematosus, Sjogren's syndrome, Hashimoto's disease, and Graves' disease. We report a rare case of anti-GPIHBP1 antibody-positive autoimmune hyperchylomicronemia with concomitant ITP, which became apparent when PSL was discontinued due to the onset of steroid-induced acute myocardial infarction. | |
35118947 | [Investigation of large granular lymphocytic leukemias: data from the laboratory of hemato | 2022 Feb 1 | Large granular lymphocytic leukemia (LGLL) is a rare clonal lymphoproliferative disorder from T or NK origin. PURPOSE: to report on the diagnostic and therapeutic management of LGLL investigated in the university hospital at Nancy, France. METHODS: retrospective (7 years) collection of clinical and biological data and patients' cohort analysis. RESULTS: Eight out of fifteen patients presented with neutropenia, including five profound neutropenia (neutrophils < 500 × 10(9)/L). Four patients had an infection. Two patients have rheumatoid arthritis and an associated Felty's syndrome, one a Sweet syndrome. Two also suffered from chronic Lymphocytic Leukemia, and one from a diffuse large B-cell lymphoma. Twelve patients had LGLL-T and 3 had a chronic LGLL-NK. Eleven out of twelve patients had a clonal LGLL-T when polymerase chain reaction assessed. No KIR clonality was sought among the 3 LGL-NK patients. Five patients out of fifteen received immunosuppressive treatment. CONCLUSION: Although using simple and robust investigations, our series demonstrates a high heterogeneity in LGLL detection and assessment. | |
35042389 | Identifying the potential role of IL-1β in the molecular mechanisms of disc degeneration | 2022 Jan | PURPOSE: We performed a bioinformatics analysis to identify the key genes that were differentially expressed between degenerative intervertebral disc (IVD) cells with and without exposure to interleukin-1β and explore the related signaling pathways and interaction networks. METHODS: The microarray data were downloaded from the Gene Expression Omnibus (27,494). Then, analyses of the gene ontology, signaling pathways, and interaction networks for the differentially expressed genes (DEGs) were conducted using tools including the Database for Annotation, Visualization, and Integrated Discovery, Metascape, Gene Set Enrichment Analysis, Search Tool for the Retrieval of Interacting Genes, Cytoscape, Venn method, and packages of the R computing language. RESULTS: A total of 260 DEGs were identified, including 161 upregulated and 99 downregulated genes. Gene Ontology annotation analysis showed that these DEGs were mainly associated with the extracellular region, chemotaxis, taxis, cytokine activity, and cytokine receptor binding. A Kyoto Encyclopedia of Genes and Genomes signaling pathway analysis showed that these DEGs were mainly involved in the of cytokine-cytokine receptor interaction, rheumatoid arthritis, tumor necrosis factor signaling pathway, Salmonella infection, and chemokine signaling pathway. The interaction network analysis indicated that 10 hub genes, including CXCL8, CXCL1, CCL20, CXCL2, CXCL5, CXCL3, CXCL6, C3, PF4, and GPER1 may play key roles in IVD degeneration. CONCLUSIONS: Bioinformatic analysis showed that CXCL8 and other nine key genes may play a role in the development of disc degeneration induced by inflammatory reactions and can be used to identify potential target genes for therapeutic applications in IVD degeneration. | |
34882360 | The phytochemical plumbagin reciprocally modulates osteoblasts and osteoclasts. | 2022 Jan 27 | Bone metabolism is essential for maintaining bone mineral density and bone strength through a balance between bone formation and bone resorption. Bone formation is associated with osteoblast activity whereas bone resorption is linked to osteoclast differentiation. Osteoblast progenitors give rise to the formation of mature osteoblasts whereas monocytes are the precursors for multi-nucleated osteoclasts. Chronic inflammation, auto-inflammation, hormonal changes or adiposity have the potential to disturb the balance between bone formation and bone loss. Several plant-derived components are described to modulate bone metabolism and alleviate osteoporosis by enhancing bone formation and inhibiting bone resorption. The plant-derived naphthoquinone plumbagin is a bioactive compound that can be isolated from the roots of the Plumbago genus. It has been used as traditional medicine for treating infectious diseases, rheumatoid arthritis and dermatological diseases. Reportedly, plumbagin exerts its biological activities primarily through induction of reactive oxygen species and triggers osteoblast-mediated bone formation. It is plausible that plumbagin's reciprocal actions - inhibiting or inducing death in osteoclasts but promoting survival or growth of osteoblasts - are a function of the synergy with bone-metabolizing hormones calcitonin, Parathormone and vitamin D. Herein, we develop a framework for plausible molecular modus operandi of plumbagin in bone metabolism. | |
34852982 | Combining current knowledge on DNA methylation-based age estimation towards the developmen | 2022 Mar | The estimation of chronological age from biological fluids has been an important quest for forensic scientists worldwide, with recent approaches exploiting the variability of DNA methylation patterns with age in order to develop the next generation of forensic 'DNA intelligence' tools for this application. Drawing from the conclusions of previous work utilising massively parallel sequencing (MPS) for this analysis, this work introduces a DNA methylation-based age estimation method for blood that exhibits the best combination of prediction accuracy and sensitivity reported to date. Statistical evaluation of markers from 51 studies using microarray data from over 4000 individuals, followed by validation using in-house generated MPS data, revealed a final set of 11 markers with the greatest potential for accurate age estimation from minimal DNA material. Utilising an algorithm based on support vector machines, the proposed model achieved an average error (MAE) of 3.3 years, with this level of accuracy retained down to 5Â ng of starting DNA input (~ 1Â ng PCR input). The accuracy of the model was retained (MAE = 3.8 years) in a separate test set of 88 samples of Spanish origin, while predictions for donors of greater forensic interest (< 55 years of age) displayed even higher accuracy (MAE = 2.6 years). Finally, no sex-related bias was observed for this model, while there were also no signs of variation observed between control and disease-associated populations for schizophrenia, rheumatoid arthritis, frontal temporal dementia and progressive supranuclear palsy in microarray data relating to the 11 markers. | |
34689057 | Emerging roles for IL-11 in inflammatory diseases. | 2022 Jan | Interleukin-11 (IL-11) is a cytokine that has been strongly implicated in the pathogenesis of fibrotic diseases and solid malignancies. Elevated IL-11 expression is also associated with several non-malignant inflammatory diseases where its function remains less well-characterized. Here, we summarize current literature surrounding the contribution of IL-11 to the pathogenesis of autoimmune inflammatory diseases, including rheumatoid arthritis, multiple sclerosis, diabetes and systemic sclerosis, as well as other chronic inflammatory conditions such as periodontitis, asthma, chronic obstructive pulmonary disease, psoriasis and colitis. | |
34088655 | Tele-Rheumatology during the COVID-19 pandemic. | 2022 Mar | INTRODUCTION: During the Covid-19 pandemic strategies to prevent transmission of the viral infection obliged our hospital to promote virtual consultations. OBJETIVE: The objective of this study is to describe the results obtained with the previous strategy of transferring activity to teleconsultation during the period of maximum impact of the pandemic. MATERIAL AND METHODS: Between 16/03 and 10/05/2020 all successive consultations in our unit were performed in virtual rheumatology teleconference (RTC) format. The socio-demographic, geo-functional and clinical characteristics of all patients were collected; a numeric verbal scale (NVS) (where 0Â =Â very dissatisfied to 10Â =Â fully satisfied) was applied to assess the degree of satisfaction of the doctor/patient with the RTC. RESULTS: 469 TC were included. Most patients seen by RTC were women, mean age: 60,83 years. Only 16% had university education. The mean distance travelled for face-to face consultation is 33 Km with a mean total time of 2Â h. Most individuals were diagnosed with osteoarthritis/soft tissue rheumatic diseases and/or osteoporosis; 21% had rheumatoid arthritis. The mean length of the TC was 9.64Â min. We find more patient satisfaction with the TC when their level of education is higher (ORÂ =Â 4.12); doctor satisfaction was higher when the individual was better able to manage the Internet (ORÂ =Â 3.01). CONCLUSION: It is possible to transfer rheumatological care activity to TC with a considerable degree of satisfaction for both the patient and the doctor. | |
35620365 | B-Scan Ultrasonography Findings in Unilateral Posterior Scleritis. | 2022 Jan | PURPOSE: To evaluate the B-scan ultrasound findings in unilateral posterior scleritis. METHODS: This was a retrospective observational case series at a tertiary uveitis clinic. The study population included patients who had been diagnosed with milder forms of unilateral posterior scleritis since 2010 and had B-scan ultrasonography of that eye. The healthy eye of each patient was considered the control eye for that patient. RESULTS: The average age of patients was 50.2 ± 17.8 (range, 18-67). Posterior scleritis was idiopathic in 6 (66.7%) patients and associated with rheumatoid arthritis in two and HLA-B27 ankylosing spondylitis in one patient. The thickness of the thickest area in the diseased eye was 2.08 ± 0.49 (range, 1.35-3.2) and the control eye was 1.53 ± 0.38 (range, 1.03-2.3). The difference between the symptomatic and control eye was statistically significantly different (P = 0.02). 1.7 mm was the cut-off-point on the receiver operating characteristics curve with the highest combined sensitivity and specificity of 87.5% and 88.9%, respectively. Comparing the thickness of the thickest section of the symptomatic eye of one patient with the same section in the other eye of the same patient, there was a difference of 20% or more in sclero-choroidal complex. CONCLUSIONS: In this study, the sclero-choroidal complex thickness higher than 1.7 mm has the highest combined sensitivity and specificity. Comparing the thickest section of the symptomatic eye of one patient with the same section in the other eye can be diagnostic. | |
35596881 | Inflammaging and Frailty in Immune-Mediated Rheumatic Diseases: How to Address and Score t | 2022 May 21 | Frailty is a new concept in rheumatology that can help identify people more likely to have less favorable outcomes. Sarcopenia and inflammaging can be regarded as the biological foundations of physical frailty. Frailty is becoming more widely accepted as an indicator of ageing and is linked to an increased risk of negative outcomes such as falls, injuries, and mortality. Frailty identifies a group of older adults that seem poorer and more fragile than their age-matched counterparts, despite sharing similar comorbidities, demography, sex, and age. Several studies suggest that inflammation affects immune-mediated pathways, multimorbidity, and frailty by inhibiting growth factors, increasing catabolism, and by disrupting homeostatic signaling. Frailty is more common in the community-dwelling population as people get older, ranging from 7 to 10% in those over 65Â years up to 40% in those who are octogenarians. Different parameters have been validated to identify frailty. These primarily relate to two conceptual models: Fried's physical frailty phenotype and Rockwood's cumulative deficit method. Immune-mediated rheumatic diseases (IMRDs), such as rheumatoid arthritis, spondyloarthritis, systemic lupus erythematosus, systemic sclerosis, and vasculitis, are leading causes of frailty in developing countries. The aim of this review was to quantitatively synthesize published literature on the prevalence of frailty in IMRDs and to summarize current evidence on the relevance and applicability of the most widely used frailty screening tools. | |
35516443 | Associations of sedentary time and physical activity with adverse health conditions: Outco | 2022 Jun | BACKGROUND: As one of the most common lifestyles today, sedentary behaviour is a risk factor for many health conditions. To inform potential behavioural guideline development, we aimed to estimate the theoretical effects of replacing sedentary behaviour with different intensity of physical activity on risks of 45 common non-communicable diseases (NCDs). METHODS: A total of 360,047 participants (aged 37-73 years) in the UK Biobank free of the 45 common non-communicable diseases (NCDs) were included. Information on sedentary time (sum of television watching, computer using and driving behaviour) and physical activity (measured by International Physical Activity Questionnaire questionnaire) were collected by self-reported at baseline. Participants were followed up for 45 NCDs diagnosis according to the ICD-10 code using linkage to national health records until 2020. Isotemporal substitution models were used to investigate substituting sedentary time with light physical activity (LPA), moderate physical activity (MPA) and vigorous physical activity (VPA) after adjusting for potential confounders. FINDING: Participants who reported > 6 h/day compared with ≤ 2 h/day sedentary time had higher risks of 12 (26.7%) of 45 NCDs, including ischemic heart disease, diabetes, chronic obstructive pulmonary disease, asthma, chronic kidney disease, chronic liver disease, thyroid disorder, depression, migraine, gout, rheumatoid arthritis and diverticular disease. Theoretically, replacing sedentary time with equivalent LPA, MPA and VPA was associated with risk reductions in 4, 6 and 10 types of NCDs, respectively. Among long sedentary time (> 6 h/day), replacing 1 h/day sedentary time with equivalent VPA showed stronger associations with 5 NCDs (diabetes, depression, chronic liver disease, diverticular disease and sleep disorder), with a larger risk reduction of 11%-31%. INTERPRETATION: Sedentary time is associated with multiple adverse health conditions, replacing sedentary time with any equivalent amounts of VPA than LPA and MPA could be associated with risk reductions of more types of NCDs.

35358276 | Association between miRNA-499 gene polymorphism and autoimmune diseases: A meta-analysis. | 2022 | INTRODUCTION: The association between miRNA-499 rs3746444 and a variety of autoimmune diseases has been reported. However, these results were contradictory and just focused on one or two autoimmune diseases. The present study aims to examine the possible association between rs3746444 polymorphism and the risk of autoimmune diseases. METHODS: The studies that evaluated the association between miRNA-499 gene polymorphism and autoimmune diseases were retrieved. Five different genetic models were used to evaluate the association. The random-effects model was used to pool the effect sizes. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to estimate the associations. Stratification analyses were performed by ethnicity and type of autoimmune diseases. False-positive report probability (FPRP) was performed for determining noteworthy associations. RESULTS: Seventeen articles (twenty studies) involving 4,376 cases and 4,991 controls were identified and included in our meta-analysis. The pooled ORs of all eligible case-control studies indicated a significant association between miRNA-499 gene polymorphism and autoimmune diseases: (T vs. C: OR = 0.877; 95% CI: 0.774, 0.993; P = 0.039). Stratified analysis indicated a significant association across both Caucasian (TT vs. TC+CC: OR = 0.779; 95% CI: 0.622, 0.976; P = 0.030) and Asian (T vs. C: OR = 0.895; 95% CI: 0.808, 0.992; P = 0.035) populations. There was also a significant association in Behcet's disease, rheumatoid arthritis, systemic lupus erythematosus, and ulcerative colitis populations. CONCLUSIONS: Our meta-analysis suggested that the miRNA-499 rs3746444 polymorphism was associated with an elevated risk of autoimmune diseases in the overall analysis as well as Caucasian and Asian populations. | |
35348365 | The outcome of an automated assessment of trabecular pattern in intraoral radiographs as a | 2022 Apr 22 | OBJECTIVES: This study aims to investigate if automated analyses of the trabecular pattern in intraoral radiographs independently contribute to fracture risk assessment when other risk factors incorporated in the Fracture Risk Assessment Tool (FRAX) are taken into account. A secondary aim is to explore the correlation between the automated trabecular pattern assessment in intraoral radiographs and Trabecular Bone Score (TBS). METHODS: A total of 567 intraoral radiographs from older females participating in a large population-based study (SUPERB) based in Gothenburg, Sweden, were selected to analyse trabecular pattern using semi-automated and fully automated software. Associations between trabecular pattern analysis and incident fractures were studied using Cox proportional hazard model, unadjusted and adjusted for FRAX risk factors (previous fracture, family history of hip fracture, smoking, corticosteroids, rheumatoid arthritis, without and with bone mineral density (BMD) of the femoral neck). In addition, the correlation between trabecular pattern analysis and TBS of the lumbar spine was investigated using Pearson correlation analysis. RESULTS: Neither the unadjusted nor the adjusted trabecular pattern analysis in intraoral radiographs was significantly associated with any fracture or major osteoporotic fracture (MOF). A weak correlation was found between semi-automated trabecular pattern analysis and TBS. No correlation was found between the fully automated trabecular pattern analysis and TBS. CONCLUSIONS: The present study shows that semi-automated and fully automated digital analyses of the trabecular pattern in intraoral radiographs do not contribute to fracture risk prediction. Furthermore, the study shows a weak correlation between semi-automated trabecular pattern analysis and TBS. | |
35166716 | Surgical Reduction of Chronic Bilateral Traumatic Dislocation of the Mandibular Condyles W | 2022 Mar 1 | BACKGROUND: Dislocation of the mandibular condyle (MC) is not a common condition, but when a traumatic case involves erosion of the middle fossa floor, it becomes a much more complicated and even rarer pathology. OBJECTIVE: To describe the management of traumatic dislocation of the MCs with erosion of the middle fossa floor. We provide a step-by-step surgical video demonstrating reestablishment of the condylar position and occlusion. METHODS: A 65-yr-old woman with rheumatoid arthritis presented after a ground-level fall. She was admitted to the intensive care unit with simultaneous complex medical conditions, intubated, and medically treated for over a month. She was seen in outpatient follow-up 2 mo later and noted to have an anterior open bite and bilateral temporomandibular joint pain. Computed tomography of the face showed bilateral dislocation of the MCs with erosion of the middle fossa floor. RESULTS: Open surgical treatment with bilateral eminectomies was performed to obtain adequate reduction, involving a multidisciplinary team including neurosurgery, oral-maxillofacial surgery, and otolaryngological surgery. She did well postoperatively. CONCLUSION: Multiple factors predispose a patient to MC dislocation, but we believe the catalyst in this case was significant manipulation of the jaw during endotracheal intubation. A chronic postoperative open bite can lead to much more difficult treatment, given bony erosion and fibrotic tissue formation. This case highlights the challenges of diagnosis and treatment of a bilateral traumatic dislocation and provides a surgical video reference description of repair and resolution. | |
35468802 | First metatarsophalangeal joint arthrodesis/fusion:Â a systematic review of modern fixatio | 2022 Apr 26 | BACKGROUND: First metatarsophalangeal joint arthrodesis is commonly performed for symptomatic end-stage hallux rigidus. It has been postulated to produce good results in the literature. Various fixation techniques offer differences in union rates, complications and functional outcomes, stirring debates about which produces the best outcomes for patients. Therefore, this review aims to synthesise and compare the outcomes of modern fixation techniques used for first metatarsophalangeal joint (FMPJ) arthrodesis. METHODS: The electronic database searched were PubMed, CINAHL, Cochrane Library, and Google Scholar. The critical appraisal skills programme tool for cohort study was used. The interventions consisted of screw(s), plate(s), and staple(s). Studies comprising outdated fixation techniques such as suture, metallic wire, external fixation, Rush rods or Steinmann pins were excluded. Participants were adults over 18 years, undergoing FMPJ arthrodesis in the UK. Studies with the population consisting primarily of revision cases, patients with rheumatoid arthritis or diabetes were excluded. RESULTS: Seven UK studies included 277 feet and a 95.7% overall union rate at a mean union time of 83.5 days. Staples had the highest union rate of 98.2% at mean union time of 84 days, followed by plates (95.2%, 92 days), and finally screws (94.9%, 71 days). The overall complication incidence is 5.8%. All of the fixation techniques produced good functional outcomes postoperatively. CONCLUSIONS: Whilst staple techniques showed the highest union rate, plating techniques are preferable over screws or staples for better results across several outcome measures, including reduced complication incidence, stability, early ambulation, and good functional outcome. The Manchester-Oxford Foot Questionnaire and EuroQol-5Dimensional are recommended as measurement tools to assess functional outcomes following FMPJ arthrodesis. | |
35388274 | Patient-Reported Outcomes in Rheumatoid Arthritis: A Key Consideration for Evaluating Bios | 2022 | PURPOSE: This review aims to provide an overview of the impact of TNFis biosimilars, with marketing authorization, in patient-reported outcome measures (PROMs) scores and explore how PROMs endpoints might add value in biosimilars uptake in RA patients. PATIENTS AND METHODS: A comprehensive search of Medline, Scopus, Lilacs, and CINAHL databases was performed for papers published between January 2012 and December 2021. For inclusion, studies had to be prospective, published in a peer-reviewed journal, published in English or Spanish language; studies using PROMs as an outcome measure. After screening title and abstracts and assessing the remaining full texts fulfilling the inclusion criteria, 31 papers were used in this narrative review. RESULTS: PROMs were used as secondary outcomes in included studies. The most frequently employed domains to assess biosimilar efficacy include physical function, patient global assessment (PtGA), health-related quality of life (HRQoL), and fatigue. The results of randomized clinical trials uniformly showed that mean change in PROMs scores is comparable between biosimilar and reference biologic treatment groups. However, open-label and real-world studies revealed high rates of discontinuation of therapy, mainly for subjective worsening of disease activity or non-specific adverse events. Even without objective clinical evidence of inflammation, patients who are considered to have active disease (higher scores on PtGA) have higher discontinuation rates of biosimilars. The available information suggests that the nocebo effect is the most likely cause for the discontinuation of biosimilars. CONCLUSION: There is scarce literature surrounding the impact of biosimilars in PROMs, especially in open-label studies. In real-life studies, biosimilars have a higher discontinuation rate than reference products. TNFis biosimilars treatment efficacy in RA depends on disease activity and other factors such as PtGA and fatigue. The nocebo effect is the best explanation for biosimilar's discontinuation. | |
35214709 | COVID-19 Vaccination Coverage in Patients with Rheumatic Diseases in a German Outpatient C | 2022 Feb 7 | BACKGROUND: In the second year of the COVID-19 pandemic, highly effective and safe vaccines became available. Since patients with rheumatic diseases show increased susceptibility to infections and typical medications raise the risk of severe COVID-19, high vaccination coverage is of significant importance to these patients. METHODS: Consecutive patients with different rheumatic diseases were asked for their vaccination status regarding COVID-19, influenza and Streptococcus pneumoniae during their routine consultations. Any reported vaccination was validated with their personal vaccination card and/or by reviewing the CovPass smartphone app. Reasons for not having a COVID-19 vaccination were documented. RESULTS: A total of 201 patients (mean age 62.3 ± 14.1 years) were included, the majority of them (44.3%) with rheumatoid arthritis, followed by spondyloarthritis (27.4%) and connective tissue diseases (21.4%). Vaccination coverage for SARS-CoV-2 was 80.1%; 85.6% got at least the first vaccination shot. Both valid influenza and pneumococcus coverage were associated with a higher probability of SARS-CoV-2 vaccination (odds ratio (OR) 6.243, 95% confidence interval (CI) 2.637-14.783, p < 0.0001 and OR 6.372, 95% CI 2.105-19.282, p = 0.0003, respectively). The main reason for a missing SARS-CoV-2 vaccination (70%) was being sceptical about the vaccine itself (i.e., the subjective impression that the vaccine was not properly tested and fear of unwanted side effects). CONCLUSIONS: Vaccination coverage against SARS-CoV-2 is high in patients with rheumatic diseases. Nevertheless, there are unmet needs regarding vaccination education to further increase vaccination rates. |
