Abstract
Duchenne muscular dystrophy (DMD) is characterized by progressive muscle wasting and the development of a dilated cardiomyopathy (DCM), which is the leading cause of death in DMD patients. Despite knowing the cause of DMD, there are currently no therapies which can prevent or reverse its inevitable progression. We have used whole body periodic acceleration (WBPA) as a novel tool to enhance intracellular constitutive nitric oxide (NO) production. WBPA adds small pulses to the circulation to increase pulsatile shear stress, thereby upregulating endothelial nitric oxide synthase (eNOS) and neuronal nitric oxide synthase (nNOS) and subsequently elevating the production of NO. Myocardial cells from dystrophin-deficient 15-month old mdx mice have contractile deficiency, which is associated with elevated concentrations of diastolic Ca2+ ([Ca2+]d), Na+ ([Na+]d), and reactive oxygen species (ROS), increased cell injury, and decreased cell viability. Treating 12-month old mdx mice with WBPA for 3 months reduced cardiomyocyte [Ca2+]d and [Na+]d overload, decreased ROS production, and upregulated expression of the protein utrophin resulting in increased cell viability, reduced cardiomyocyte damage, and improved contractile function compared to untreated mdx mice.

Abstract
Osteoarthritis (OA) is a complex degenerative disease in which joint homeostasis is disrupted, leading to synovial inflammation, cartilage degradation, subchondral bone remodeling, and resulting in pain and joint disability. Yet, the development of new treatment strategies to restore the equilibrium of the osteoarthritic joint remains a challenge. Numerous studies have revealed that dietary components and/or natural products have anti-inflammatory, antioxidant, anti-bone-resorption, and anabolic potential and have received much attention toward the development of new therapeutic strategies for OA treatment. In the present review, we provide an overview of current and emerging natural-product-based research treatments for OA management by drawing attention to experimental, pre-clinical, and clinical models. Herein, we review current and emerging natural-product-based research treatments for OA management.

Psychometric validation of a patient-reported outcome questionnaire (Qualipsosex) assessing the impact of psoriasis and psoriatic arthritis on patient perception of sexuality. Medicine (Baltimore) 2021; 100:e24168. [PMID: 33429800 PMCID: PMC7793412 DOI: 10.1097/md.0000000000024168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 10/30/2020] [Accepted: 12/10/2020] [Indexed: 01/05/2023] Open
Abstract
ABSTRACT Psoriasis (Pso) and psoriatic arthritis (PsA) frequently have a negative impact on patients' sexual health. We have developed a specific questionnaire assessing the impact of Pso and PsA on patient perception of sexuality: the QualipsoSex Questionnaire (QSQ). The aim of the present study was to further validate this questionnaire by checking its psychometric properties including validity, reliability, and responsiveness.A cross sectional observational study with a longitudinal component for responsiveness and test-retest reliability was performed in 12 centers in France including 7 dermatologists and 5 rheumatologists. Psychometric properties were examined according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) check-list.At baseline, 114 patients had Pso and 35 patients had PsA including 17 peripheral arthritis, 4 axial disease, 13 patients with both axial disease and peripheral arthritis and one patient with an undifferentiated phenotype. The mean Pso Area and Severity Index score was 12.5. Genital organs were involved in 44.7% of Pso cases. Internal consistency, construct validity, and reliability were good with Cronbach's α coefficient, measure of sampling adequacy and intraclass correlation coefficient respectively at 0.87, 0.84, and 0.93. The QSQ also demonstrated acceptable sensitivity to change.The QSQ has demonstrated good psychometric properties fulfilling the validation process relative to the recommendations of the COSMIN check list. The QSQ is simple to score and may hopefully be valuable in clinical practice and in clinical trials.

Abstract
BACKGROUND The impact of psoriasis on quality of life (QoL), sexuality and empathy requires better understanding in patient-partner relationships. OBJECTIVES To evaluate the influence of psoriasis on partner QoL, presence of sexual dysfunction (SDy) in couples and empathy in partners of psoriasis patients. METHODS A total of 183 adult psoriasis patients and their partners participated in this observational, cross-sectional and non-comparative study. Severity of psoriasis was measured using the Psoriasis Area and Severity Index. Patient QoL was assessed using the Dermatology Life Quality Index and the Short Form-12 (SF12). The impact of psoriasis on partner QoL was measured with the Family Pso and the SF12. Presence of SDy and empathy in partners were assessed using the Family Pso. RESULTS Overall, 49.7% of the patients had moderate-to-severe psoriasis. Patient psoriasis severity and patient QoL were correlated with partner psychological distress. The largest QoL impairment was observed in female patients with moderate-to-severe psoriasis. The stronger QoL alteration observed in female psoriasis patients, compared to their partners, was not observed in male psoriasis patients vs. their partners. There was no relationship between partner QoL and patient age and duration of psoriasis. Most patients, but less than half of the partners, reported SDy with age being a being a significantly more important impacting factor than disease severity. Both psoriasis clinical severity and/or a significant impact on QoL were associated factors for SDy in male partners of psoriasis women, but not in female partners of psoriatic men. Reporting empathy was higher among young male partners of psoriasis patients. In both male and female partners, patient psoriasis clinical severity was not associated with empathy. CONCLUSIONS Psoriasis impact on patient-partner QoL, sexuality and empathy should be considered more thoroughly by dermatologists when formulating treatment plans and making treatment decisions.

Abstract
BACKGROUND While some information on psoriasis impact on pregnancy is available, very little is known on the preoccupations of women afflicted by the disease or on the dermatologists' (D) positioning as to psoriasis and pregnancy. The 'Objectifs Peau' project demonstrated a 4.7% prevalence of psoriasis in women aged 18-45 years in France. OBJECTIVE This project sought to further address these issues in view of a targeted action plan. METHODS A questionnaire was made available to 361 D of different types. RESULTS Overall, 152 D answered the questionnaire, 50.7% working in private or mixed practice and 49.3% in hospitals, with 63% females (DF) and 37% males (DM). Over the last 3 months, the mean percentage of women of child-bearing age seen by these D was 28.6%. The main issue addressed by D upon psoriasis diagnosis was the patient's wish to become pregnant in the short-term (84%), while the compatibility of drug treatment with pregnancy was the issue prioritized by patients (64%). Among DM and DF, 46% and 29% reported having been confronted with an unplanned pregnancy, with their reaction mainly dependent on the treatment taken in 66%. Regarding follow-up, 26% D declared having shared their decision-making with gynaecologists, while 56% considered the first pregnancy trimester to be the highest-risk period. Only 28% D were familiar with existing recommendations, with only 21% of them considering them appropriate. CONCLUSION Overall, 26.2% of French psoriasis women are of child-bearing potential, in line with our dataset (28.6%). Only 56% D considered the 1st pregnancy trimester to be the highest-risk period, with only one-third familiar with existing recommendations. The gap between recommendations and actual practices must be addressed through policies that take women's preoccupations better into account.

Abstract
Psoriasis and psoriatic arthritis impact sexuality and intimate relationships in both men and women, and can be associated with sexual dysfunctions.The aim of this study was to develop and validate a specific questionnaire assessing the impact of psoriasis and psoriatic arthritis on patients' sexuality. Two focus groups of patients, concerned by sexuality, were conducted in February 2015. Based on the verbatim transcripts, a content analysis was performed by a psychologist trained in qualitative procedures.After analysis of the verbatim reports by the research group, a preliminary questionnaire comprising 22 questions was drawn up. The areas covered by the questions concerned: the quality of daily life, tolerance of the cutaneous state by the patient, tiredness, mobility and flexibility of the joints, outside activities involving movement of all or part of the body. In the following step the questions were then submitted to a panel of experts for selection using a Delphi method. The experts were questioned about item relevance and content. After expert consensus had been reached, the instructions to participants completing the questionnaire, the wording of items, and the possible answers were finalized.The final questionnaire (comprising 14 questions) is entitled "Questionnaire of sexual quality of life perceived by patients with cutaneous and/or articular psoriasis" (short denomination: Qualipsosex). The quantitative step has not yet been conducted. This step will aim to evaluate the metrologic qualities (reliability, validity, and responsiveness) of the questionnaire and will need to be validated according to the consensus-based standards for the selection of health measurement instrument checklist.

Abstract
OBJECTIVE The primary aim of this systematic review was to determine if inertial flywheel resistance training is superior to gravity-dependent resistance training in improving muscle strength. The secondary aim was to determine whether inertial flywheel resistance training is superior to gravity-dependent resistance training in improving other muscular adaptations. DESIGN A systematic review with meta-analyses of randomised and non-randomised controlled trials. METHODS We searched MEDLINE, Scopus, SPORTDiscus, Web of Science and Cochrane Central Register of Controlled Trials with no publication date restrictions until November 2016. We performed meta-analyses on randomised and non-randomised controlled trials to determine the standardized mean difference between the effects of inertial flywheel and gravity-dependent resistance training on muscle strength. A total of 76 and 71 participants were included in the primary and secondary analyses, respectively. RESULTS After systematic review, we included three randomised and four non-randomised controlled trials. In the primary analysis for the primary outcome muscle strength, the pooled results from randomised controlled trials showed no difference (SMD=-0.05; 95%CI -0.51 to 0.40; p=0.82; I2=0%). In the secondary analyses of the primary outcome, the pooled results from non-randomised controlled trials showed no difference (SMD=0.02; 95%CI -0.45 to 0.49; p=0.93; I2=0%; and SMD=0.03; 95%CI -0.43 to 0.50; p=0.88; I2=0%). Meta-analysis on secondary outcomes could not be performed. CONCLUSION Based on the available data, inertial flywheel resistance training was not superior to gravity-dependent resistance training in enhancing muscle strength. Data for other strength variables and other muscular adaptations was insufficient to draw firm conclusions from.

Abstract
Iatrogenic Kaposi sarcoma (KS) has previously been reported in patients with bullous pemphigoid (BP), in relation to systemic steroids. To report three cases of previously unreported cutaneous KS during treatment with superpotent topical steroids (STS) and methotrexate (MTX). All patients were elderly men with BP treated with STS for 2 to 32 months (cumulative doses: 2,700-9,150 g) before MTX was introduced (dosage: 10-12.5 mg/week). KS occurred one to nine months after the combined therapy. In one case, KS rapidly resolved after withdrawal of MTX. In two cases, vinblastine and/or radiotherapy were required to achieve regression of KS. Human herpes virus 8 (HHV8) latency-associated nuclear antigen was not expressed in BP lesions biopsied prior to development of KS (n = 3), but HHV8 DNA was detected in BP lesions from the patient with the most aggressive KS. Several predisposing factors were identified, including sex and age, high cumulative doses of STS, combination with MTX, and impaired immune status. In such cases, serum antibodies against HHV8 infection may be investigated in BP patients before introduction of MTX in order to guide clinical monitoring.

Abstract
BACKGROUND The prognostic relevance of a high blood neutrophil-to-lymphocyte ratio (NLR) has been reported in many cancers, although, to our knowledge, not investigated in patients with Merkel cell carcinoma (MCC) to date. OBJECTIVE We assessed whether the NLR at baseline was associated with specific survival and recurrence-free survival in MCC. METHODS We retrospectively included MCC cases between 1999 and 2015 and collected clinical data, blood cell count at baseline, and outcome. A Cox model was used to identify factors associated with recurrence and death from MCC. RESULTS Among the 75 patients included in the study, a high NLR at baseline (NLR ≥4) was associated with death from MCC in univariate (hazard ratio 2.76, 95% confidence interval 1.15-6.62, P = .023) and multivariate (hazard ratio 3.30, 95% confidence interval 1.21-9.01, P = .020) analysis, but not with recurrence. LIMITATIONS Because of the retrospective design, we excluded patients with missing data and not all confounding factors that may influence the NLR were available. CONCLUSION A high NLR at baseline was independently associated with specific mortality in patients with MCC. The NLR seems to constitute an easily available and inexpensive prognostic biomarker at baseline.

Abstract
BACKGROUND Merkel cell polyomavirus (MCPyV) is the main aetiological agent of Merkel cell carcinoma (MCC). Serum antibodies against the major MCPyV capsid protein (VP1) are detected in the general population, whereas antibodies against MCPyV oncoproteins (T antigens) have been reported specifically in patients with MCC. OBJECTIVES The primary aim was to assess whether detection of serum antibodies against MCPyV proteins at baseline was associated with disease outcome in patients with MCC. The secondary aim was to establish whether evolution of these antibodies during follow-up was associated with the course of the disease. METHODS Serum T-antigen and VP1 antibodies were assessed by enzyme-linked immunosorbent assay using recombinant proteins in a cohort of 143 patients with MCC, including 84 patients with serum samples available at baseline. RESULTS Low titres of VP1 antibodies at baseline (< 10 000) were significantly and independently associated with increased risk of recurrence [hazard ratio (HR) 2·71, 95% confidence interval (CI) 1·13-6·53, P = 0·026] and death (HR 3·74, 95% CI 1·53-9·18, P = 0·004), whereas T-antigen antibodies were not found to be associated with outcome. VP1 antibodies did not differ between patients in remission and those with recurrence or progression during follow-up. However, T-antigen antibodies were more frequently detected in patients with recurrence or progression at 12 months (P = 0·020) and 24 months (P = 0·016) after diagnosis. CONCLUSIONS VP1 antibodies constitute a prognostic marker at baseline, whereas T-antigen antibodies constitute a marker of disease recurrence or progression if detected > 12 months after diagnosis.

Abstract
INTRODUCTION Urinary tract infections due to Candida species are mostly encountered in hospital environment. The management of candiduria on ureteral catheter is not consensual. The objective of our work was to make a review of medical literature related to definition, physiopathology, management and prevention of candiduria on ureteral catheter. MATERIAL AND METHODS The research was made on Medline using the following keywords: Candida; fungal; urinary tract infection; ureteral stent; ureteric stent; double-J pigtail. RESULTS The threshold defining candiduria is 10(5) CFU/mL. Candiduria corresponds to many different clinical presentations from colonization to candidemia. Species found are mostly Candida albicans (19-72%) and Candida glabrata (15.6-49.4%). The colonization of ureteral stent due to Candida is of 10% and comes with candiduria in 40% of the cases, due to the presence of biofilm. Prevention of infections on ureteral stents requires a regular change of material every 3-6 months depending on the patients risk groups. In case of symptomatic candiduria on ureteral stent, an anti-fungal therapy should be initiated 48 hours to 3 weeks before the change of the stent, in order to get a sterilization of urines and prevent the recolonization of the stent. Fluconazole is the drug of choice to use. CONCLUSION Colonization of ureteral stents due to Candida is common and can be responsible of symptomatic infection. Anti-fungal therapy should be introduced before the change of the stent but a consensual duration of treatment before surgery is not found in the literature.

APOA5 gene expression in the human intestinal tissue and its response to in vitro exposure to fatty acid and fibrate. Nutr Metab Cardiovasc Dis 2012; 22:756-762.

Abstract
BACKGROUND AND AIMS APOA5, a key gene regulating triglyceride (TG) levels, is reported to be expressed exclusively in the liver where it may regulate TG-rich particle synthesis and secretion. Since the same lipoprotein processing occurs in the intestine, we have postulated that this organ would also express APOA5. METHODS AND RESULTS We have detected the APOA5 gene expression in C57BL/6J mouse and in human small intestine samples. In humans, it is expressed mainly in the duodenum and colon, with messenger RNA (mRNA) levels four orders of magnitude lower than in the liver, and the protein product being one-sixth of the liver equivalent. Subsequently, we carried out in vitro experiments in TC-7/CaCo(2) human intestinal cells to analyse the expression of APOA5, APOC3, APOB and MTP genes after the incubation with long- and short-chain fatty acids, and a peroxisome proliferator-activated receptor alpha (PPARα) agonist (Wy 14643, a fibrate therapeutic agent). In the TC-7 cell line, APOA5 expression was significantly upregulated by saturated fatty acids. The short-chain fatty acid butyrate increased APOA5 expression almost fourfold while APOB was downregulated by increasing butyrate concentrations. When TC-7 cells were incubated with PPARα agonist, the APOA5 expression was increased by 60%, while the expression of APOB, MTP and APOC3 was decreased by 50%, 30% and 45%, respectively. CONCLUSION Our results demonstrate that APOA5 is expressed in the intestine, albeit at a much lower concentration than in the liver. While it remains to be determined whether intestinal apo A-V is functional, our in vitro experiments show that its expression is modifiable by dietary and pharmacological stimuli.

Abstract
OBJECTIVES To describe clinicopathologic features and to identify prognostic factors in a large series of primary cutaneous diffuse large B-cell lymphoma, leg type (PCLBCL LT), as defined in the recent World Health Organization-European Organization for Research and Treatment of Cancer classification of cutaneous lymphomas. DESIGN Retrospective multicenter study from the French Study Group on Cutaneous Lymphomas. SETTING Nineteen departments of dermatology in 10 regions of France. PATIENTS Sixty patients with a PCLBCL LT included in the registry of the French Study Group on Cutaneous Lymphomas. MAIN OUTCOME MEASURES Age, sex, outcome, therapy, B symptoms, cutaneous extent, number of lesions, location (leg vs nonleg), serum lactate dehydrogenase level, and MUM-1 and Bcl-2 expression were recorded. Disease-specific survival was used as the main end point. Prognostic factors were identified using a Cox proportional hazards model. RESULTS Primary cutaneous diffuse large B-cell lymphoma, leg type is characterized by a predilection for the leg (72%), a high proportion of Bcl-2 expression (85%), an advanced age at onset (mean age, 76 years), and frequent relapses and extracutaneous dissemination. The overall 5-year disease-specific survival rate was 41%. Location on the leg and multiple skin lesions were predictive of death in multivariate analysis. Although no variable related to therapy was significantly associated with survival, patients recently treated with combinations of anthracycline-containing chemotherapies and rituximab had a more favorable short-term outcome. CONCLUSIONS Primary cutaneous diffuse large B-cell lymphoma, leg type is a distinct entity with a poor prognosis, particularly in patients with multiple tumors on the legs. Despite the advanced age of many patients, the prognosis could be improved with combinations of anthracycline-containing chemotherapies and rituximab.

Elevated resting [Ca2+]iin myotubes expressing malignant hyperthermia RyR1 cDNAs is partially restored by modulation of passive calcium leak from the SR. Am J Physiol Cell Physiol 2007; 292:C1591-8.

Abstract
Malignant hyperthermia (MH) is a pharmacogenetic disorder of skeletal muscle triggered in susceptible individuals by inhalation anesthetics and depolarizing skeletal muscle relaxants. This syndrome has been linked to a missense mutation in the type 1 ryanodine receptor (RyR1) in more than 50% of cases studied to date. Using double-barreled Ca2+microelectrodes in myotubes expressing wild-type RyR1 (WTRyR1) or RyR1 with one of four common MH mutations (MHRyR1), we measured resting intracellular Ca2+concentration ([Ca2+]i). Changes in resting [Ca2+]iproduced by several drugs known to modulate the RyR1 channel complex were investigated. We found that myotubes expressing any of theMHRyR1s had a 2.0- to 3.7-fold higher resting [Ca2+]ithan those expressingWTRyR1. Exposure of myotubes expressingMHRyR1s to ryanodine (500 μM) or (2,6-dichloro-4-aminophenyl)isopropylamine (FLA 365; 20 μM) had no effects on their resting [Ca2+]i. However, when myotubes were exposed to bastadin 5 alone or to a combination of ryanodine and bastadin 5, the resting [Ca2+]iwas significantly reduced ( P < 0.01). Interestingly, the percent decrease in resting [Ca2+]iin myotubes expressingMHRyR1s was significantly greater than that forWTRyR1. From these data, we propose that the high resting myoplasmic [Ca2+]iinMHRyR1 expressing myotubes is due in part to a related structural conformation ofMHRyR1s that favors “passive” calcium leak from the sarcoplasmic reticulum.

Abstract
BACKGROUND Malignant hyperthermia is a pharmacogenetic disorder affecting humans, dogs, pigs, and horses. In the majority of human cases and all cases in animals, malignant hyperthermia has been associated with missense mutations in the skeletal ryanodine receptor (RyR1). METHODS The authors used a "knock-in" targeting vector to create mice carrying the RyR1 R163C malignant hyperthermia mutation. RESULTS Validation of this new mouse model of human malignant hyperthermia susceptibility includes (1) proof of transcription of the R163C allele and expression of ryanodine receptor protein in R163C heterozygous and R163C homozygous animals; (2) fulminant malignant hyperthermia episodes in R163C heterozygous mice after exposure to 1.25-1.75% halothane or an ambient temperature of 42 degrees C characterized by increased rectal temperature, respiratory rate, and inspiratory effort, with significant blood biochemical changes indicating metabolic acidosis, ending in death and hyperacute rigor mortis; (3) intraperitoneal pretreatment with dantrolene provided 100% protection from the halothane-triggered fulminant malignant hyperthermia episode; (4) significantly increased sensitivity (decreased effective concentration causing 50% of the maximal response) of R163C heterozygous and homozygous myotubes to caffeine, 4-chloro-m-cresol, and K-induced depolarization; (5) R163C heterozygous and homozygous myotubes have a significantly increased resting intracellular Ca concentration compared with wild type; (6) R163C heterozygous sarcoplasmic reticulum membranes have a twofold higher affinity (Kd = 35.4 nm) for [H]ryanodine binding compared with wild type (Kd = 80.1 nm) and a diminished inhibitory regulation by Mg. CONCLUSIONS Heterozygous R163C mice represent a valid model for studying the mechanisms that cause the human malignant hyperthermia syndrome.
