Background: The association of multiple sclerosis (MS) with joint diseases has been established. However, the impact of MS on postoperative outcomes following total joint arthroplasty (TJA) remains controversial. Therefore, a systematic review of the literature is warranted to ascertain the relationship between MS and adverse outcomes post-TJA.

Methods: A systematic literature search of PubMed, Embase, Scopus, and the Cochrane Library from inception to 1 March 2023 was conducted to identify observational studies comparing post-TJA outcomes in MS and non-MS patients. Two investigators independently screened titles, abstracts, and full-text articles for eligibility. A random-effects model was used to calculate odds ratios (OR), mean differences (MD), and corresponding 95% confidence intervals (CI).

Results: Seven retrospective cohort studies published between 2018 and 2022 met the inclusion criteria. Patients with MS had a higher risk of medical, surgical, and overall complications than patients without MS. Similarly, the MS group was more likely to experience an extended hospital stay, non-home discharge, and revision surgery compared to the control group. Joint infection and implant instability were also more common in patients with MS.

Conclusion: Although TJA may benefit MS patients, current evidence suggests that their postoperative outcomes may be inferior to those of non-MS patients. Thus, orthopaedic surgeons should inform MS patients of potential risks and perform preoperative optimization individually when considering elective arthroplasty.

Introduction: As the most frequent chronic neurological disorder in young adults, Multiple sclerosis (MS) significantly affects neurological function, particularly the autonomic nervous system. While the physical symptoms are visible, MS also causes hidden effects like sexual dysfunction. Research indicates that sexual disorders are more prevalent in MS patients compared to other neurological conditions and are approximately five times more common than in the general population.

Increased plasma DOPA decarboxylase levels in Lewy body disorders are driven by dopaminergic treatment.

Nat Commun

January 2025

Neurochemistry Laboratory, Department of Laboratory Medicine, Amsterdam Neuroscience, VU University Medical Center, Amsterdam UMC, Amsterdam, The Netherlands.

DOPA Decarboxylase (DDC) has been proposed as a cerebrospinal fluid (CSF) biomarker with increased concentrations in Lewy body disorders (LBDs) and highest levels in patients receiving dopaminergic treatment. Here we evaluate plasma DDC, measured by proximity extension assay, and the effect of dopaminergic treatment in three independent LBD (with a focus on dementia with Lewy bodies (DLB) and Parkinson's disease (PD)) cohorts: an autopsy-confirmed cohort (n = 71), a large multicenter, cross-dementia cohort (n = 1498) and a longitudinal cohort with detailed treatment information (n = 66, median follow-up time[IQR] = 4[4, 4] years). Plasma DDC was not altered between different LBDs and other disease groups or controls in absence of treatment.

Ocrelizumab (OCR) and Natalizumab (NTZ) are highly effective treatments widely used in Multiple Sclerosis (MS). However, long-term, real-world comparative data on clinical effectiveness, safety and treatment persistence are limited. This retrospective analysis included relapsing and progressive MS patients initiating treatment at two Italian Universities ("La Sapienza" and "Federico II").

Voltage-gated potassium conductances [Formula: see text] play a critical role not only in normal neural function, but also in many neurological disorders and related therapeutic interventions. In particular, in an important animal model of epileptic seizures, 4-aminopyridine (4-AP) administration is thought to induce seizures by reducing [Formula: see text] in cortex and other brain areas. Interestingly, 4-AP has also been useful in the treatment of neurological disorders such as multiple sclerosis (MS) and spinal cord injury, where it is thought to improve action potential propagation in axonal fibers.

Development and testing the psychometric properties of 20 bolt-on items for the EQ-5D-5L across 31 rare diseases.

Value Health

January 2025

Department of Cardiology and State Key Laboratory of Complex Severe and Rare Diseases, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, Beijing, China.

Objective: Our objective was to develop and assess the psychometric properties of relevant bolt-on items for the EQ-5D-5L in patients with rare diseases (RDs).

Methods: Nineteen new EQ-5D-5L bolt-ons were developed based on literature review, expert input and qualitative interviews and focus groups with patients, caregivers and representatives of patient associations. A nationwide, cross-sectional, web-based survey in China included patients or caregivers of patients with 31 RDs in China (n=9,190).
