Sex-Related Disparities in Cardiovascular Outcomes Among Older Adults With Late-Onset Hypertension.

BACKGROUND: It is unclear whether sex-based differences in cardiovascular outcomes exist in late-onset hypertension. METHODS: This is a population-based cohort study in Ontario, Canada of 266 273 adults, aged ≥66 years with newly diagnosed hypertension. We determined the incidence of the primary composite cardiovascular outcome (myocardial infarction, stroke, and congestive heart failure), all-cause mortality, and cardiovascular death by sex using Cox proportional hazard models adjusted for demographic factors and comorbidities. RESULTS: The mean age of the total cohort was 74 years, and 135 531 (51%) were female. Over a median follow-up of 6.6 (4.7-9.0) years, females experienced a lower crude incidence rate (per 1000 person-years) than males for the primary composite cardiovascular outcome (287.3 versus 311.7), death (238.4 versus 251.4), and cardiovascular death (395.7 versus 439.6), P<0.001. The risk of primary composite cardiovascular outcome was lower among females (adjusted hazard ratio, 0.75 [95% CI, 0.73-0.76]; P<0.001) than in males. This was consistent after adjusting for the competing risk of all-cause death with a subdistributional hazard ratio, 0.88 ([95% CI, 0.86-0.91]; P<0.001). CONCLUSIONS: Females had a lower risk of cardiovascular outcomes compared with males within a population characterized by advanced age and new hypertension. Our results highlight that the severity of outcomes is influenced by sex in relation to the age at which hypertension is diagnosed. Further studies are required to identify sex-specific variations in the diagnosis and management of late-onset hypertension due to its high incidence in this group.

Efficiency and tolerance of second-line triple BRAF inhibitor/MEK inhibitor/anti-PD1 combined therapy in BRAF mutated melanoma patients with central nervous system metastases occurring during first-line combined targeted therapy: a real-life survey.

Although current systemic therapies significantly improved the outcome of advanced melanoma, the prognosis of patient with central nervous system (CNS) metastases remains poor especially when clinically symptomatic. We aimed to investigate the efficiency of CNS targets and tolerance of second-line combined anti-PD1/dual-targeted anti-BRAF/anti-MEK therapy implemented in patients with CNS progression after initially efficient first-line combined targeted therapy in patients with BRAF-mutated melanoma in a real-life setting. A monocentric retrospective analysis including all such patients treated from January 2017 to January 2022 was conducted in our tertiary referral center. The response of CNS lesions to second-line triple therapy was assessed through monthly clinical and at least quarterly morphological (according to RECIST criteria) evaluation. Tolerance data were also collected. Seventeen patients were included with a mean follow-up of 2.59 (±2.43) months. Only 1 patient displayed a significant clinical and morphological response. No statistically significant difference was observed between patients receiving or not additional local therapy (mainly radiotherapy) as to response achievement. Immunotherapy was permanently discontinued in 1 patient owing to grade 4 toxicity. Mean PFS and OS after CNS progression were 2.59 and 4.12 months, respectively. In this real-life survey, the subsequent addition of anti-PD1 to combined targeted therapy in melanoma patients with upfront CNS metastases did not result in significant response of CNS targets in most BRAF mutated melanoma patients with secondary CNS progression after initially successful first-line combined targeted therapy.

Evolution of Bullous Pemphigoid Clinical Pattern over Time: A 17-Year Single-Centre Retrospective Survey of 312 Cases.

BACKGROUND AND OBJECTIVES: Bullous pemphigoid (BP) clinical profile may have evolved during the last 2 decades. A retrospective, single-centre analysis investigated a possible shift of clinical presentation of the disease over time regarding both lesions' clinical pattern and locations and more particularly an increased frequency of characteristics considered as less classical regarding the usual clinical description of BP. PATIENTS AND METHODS: Initial clinical data from all BP patients treated between January 2001 and April 2017 in a reference centre were collected and compared between four 4-year successive chronological subsets (G1 to G4). RESULTS: 213/312 patients retained for final analysis (68.3%) displayed at least one initial non-classical characteristic, mainly head and neck, palmo-plantar, and/or mucosal involvement. Chronological analysis confirmed a significant increase over time of the percentage of patients displaying such features (G1 57.9% vs. G4 73.7%, p = 0.041). CONCLUSION: Changes in BP clinical pattern may have occurred over the last two decades with the progressive emergence of forms with a number of less classical features. No significant clinical difference was observed between patients receiving or not DPP4 inhibitors at the time of diagnosis.

Biologics combined with conventional systemic agents for the treatment of children with severe psoriasis. Real-life data from the BiPe cohorts and a practice survey among French and Italian pediatric dermatologists.

Combined therapies involve the use of multiple drugs to increase efficacy and reduce the toxicity of individual treatments. We evaluated the use of combinations of conventional systemic therapies and biologics in children with psoriasis in daily practice. This two-part study used data from the 170 children in the Franco-Italian BiPe cohorts to evaluate the use, efficacy, and safety of combined conventional systemic-biologic therapies, and from a survey carried out among French and Italian dermatologists to better understand the reasons for using or avoiding these combinations. In total, 33 children (19.4%) from 13 dermatology centers received 48 combined conventional systemic-biologic therapies (cumulative duration: 43.6 years), including three triple combination therapies (acitretin-methotrexate, with a TNF-alpha inhibitor). A total of 14 different combinations were used, most frequently etanercept-acitretin (n = 10), adalimumab-acitretin (n = 7), adalimumab-methotrexate (n = 5), and ustekinumab-methotrexate (n = 5). The combined therapies were started at biologic initiation in 41 cases (85.4%), and after a period of biologic monotherapy in the remaining 7 cases. Mean PGA and PASI scores decreased between baseline and M3 with all the combinations used. Four serious adverse events were reported, all with favorable outcomes. The survey was completed by 61 dermatologists: 39 (63.9%) had previously used or planned to use the combined therapies, most commonly TNF-alpha inhibitors with acitretin or methotrexate. The main reason for using these treatments was to improve the outcome of biologic therapies in cases of partial efficacy or loss of efficacy. Combined therapies have been used frequently in the treatment of childhood psoriasis, in a range of clinical situations and in variable drug combinations, without significant toxicity. Although the use of these combined therapies needs to be clarified in future management guidelines, these combined therapies should be considered for the treatment of children with severe psoriasis, psoriatic arthritis, and recalcitrant disease.

How to Define Mild to Severe Hidradenitis Suppurativa? A Simple New Tool Based on Latent Class Analysis of EPIVER Data Study.

Purpose: Hidradenitis suppurativa (HS) is an inflammatory skin disease characterized by recurrent or chronic painful and suppurating lesions in the apocrine gland-bearing regions. The lack of knowledge about HS and its extremely heterogeneous clinical presentation, in terms of both lesion appearance and sites of involvement, frequently delay its diagnosis for several years. Objectives: in this study, using the latent class analysis, it was demonstrated that severity of HS could be evaluated not only with clinical or surgical characteristics but also with gender specificities. Patients and Methods: Clinical and sociodemographic data of HS patients were retrospectively analysed with the latent class method in order to create a classification tool of disease severity. Results: From the study of 1428 HS patients (544 men and 884 women), two classification models, depending on gender, were developed. Each classification model was composed of three distinct latent classes clearly identified and defined from mild-to-severe cases of HS. These classification models of HS severity were not distorted by patient ages and were coherent with Hurley stages but were more clinically precise. Conclusion: In this study, a convenient classification tool, useful for facilitating decision support in routine practice, has been developed. This tool could be used to define clinical subgroups within a study population.

New-onset inflammatory bowel diseases among IL-17 inhibitor-treated patients: results from the case-control MISSIL study.

OBJECTIVES: To describe new-onset IBD (new IBD) in patients treated with IL-17 inhibitors (IL-17i), to assess their incidence and to identify their risk factors in real life. METHODS: A French national registry (MISSIL) aimed to report all cases of new IBD in patients treated with IL-17i from January 2016 to December 2019. Using the estimated number of patients treated by IL-17 in France during the study period, the annual incidence rates of new IBD was reported in IL-17i-treated patients. A case-control study was performed with two controls per new IBD case matched by gender, age and underlying inflammatory disease. RESULTS: Thirty-one cases of new IBD under IL-17i were collected: 27 patients treated for spondyloarthritis and four patients for psoriasis. All were observed with secukinumab (SEK). The median time to onset of new IBD symptoms was 4.0 (1.5-7.5) months. SEK was discontinued in all patients. The evolution was favourable with complete resolution (17/31), improvement (7/31) or stabilization (5/31). Two patients died: one due to a massive myocardial infarction and one due to post-colectomy complications. The incidence of new IBD decreased from 0.69/100 patient-years [PY] (7/1010) in 2016 to 0.08/100 PY (6/7951) in 2019. No previous treatment with etanercept (odds ratio [OR] = 0.33, 95% CI: 0.14-0.80, P = 0.014) and low number of previous biologic therapies (OR = 0.67, 95% CI: 0.47, 0.94, P = 0.021) were significantly associated with new IBD. CONCLUSION: The incidence of new IBD was low and decreased from 2016 to 2019. The outcome was favourable in 24 out of 31 patients, but two patients died.

Switching biologics in children with psoriasis: Results from the BiPe cohort.

BACKGROUND: There is currently little information on switching biologics in pediatric psoriasis. OBJECTIVE: To evaluate the real-world clinical practice and safety of switching biologics in the "Biological Treatments for Pediatric Psoriasis" (BiPe) cohort. METHODS: Data for all 134 patients included in the BiPe cohort were analyzed. A further evaluation of the subpopulation of patients who switched from a first-line biologic to a second-line biologic was then conducted. Drug survival rates were also compared between biologics given as first-line or second-line agents. RESULTS: Overall, 29 patients (female: 55%; mean age: 16.6 ± 3.0 years) switched between two biologics. Etanercept (ETN) was the first-line biologic used in 23 patients: 16 (69.6%) switched to adalimumab (ADA) and seven (30.4%) to ustekinumab (UST). Six patients received first-line ADA and switched to UST. Loss of efficacy (62.1%), primary inefficacy (20.7%), and parental choice (6.9%) were the main reasons for switching biologics. One (3.4%) of the switches was performed because of adverse events or intolerance. For UST and ADA, the 18-month drug survival rate did not differ according to whether the agent was given as a first-line or second-line biologic (UST: P = .24; ADA: P = .68). No significant differences in drug survival rates were observed between the three different switches (ADA to UST, ETN to ADA, and ETN to UST). CONCLUSION: Our study provided key insights into the real-life clinical practice of switching biologics in pediatric psoriasis patients. However, more information and guidance on switching biologics in pediatric psoriasis are needed to improve real-life practice and outcomes.

Evaluation of Thalidomide Treatment of Patients With Chronic Erythema Multiforme: A Multicenter Retrospective Cohort Study.

IMPORTANCE: Erythema multiforme (EM) may become long term, with a recurrent or persistent course. First-line treatment for chronic EM is valaciclovir. There is no consensus for selection of second-line treatment of chronic EM. OBJECTIVE: The aim of this study was to assess the effectiveness of treatment with thalidomide for patients with chronic EM. DESIGN, SETTING, AND PARTICIPANTS: In this retrospective national multicenter cohort study, among 68 French hospital dermatology departments contacted by e-mail, 10 reported having eligible cases. All adults aged 18 years or older under dermatology care for chronic EM (including recurrent and persistent forms) who had received thalidomide between 2010 and 2018 were included. Analyses were conducted from June 24, 2019, to December 31, 2019. MAIN OUTCOMES AND MEASURES: The primary outcome was the proportion of patients who did not experience an EM flare within 6 months of initiating thalidomide treatment for recurrent EM or with complete clearance at 6 months for persistent EM (complete remission). RESULTS: Overall, 35 patients with chronic EM (median [range] age, 33 [15-65] years; 20 [57%] female) experienced failure of at least 1 previous treatment prior to initiating treatment with thalidomide. After 6 months of continuous thalidomide treatment, 23 (66%) were in complete remission, 5 (14%) had stopped the treatment, and 7 (20%) experienced at least 1 flare. The median (IQR) initial dose followed by remission was 50 (50-100) mg/d. Main adverse effects were asthenia (16 [46%]) and neuropathy (14 [40%]). Twenty-five (71%) of patients stopped thalidomide treatment after a median (IQR) of 12 (8-20) months owing to lack of effect (7/25 [28%]), neuropathy or another adverse effect (14/25 [56%]), or long-term complete remission (4/25 [16%]). Low-dose thalidomide, less than 50 mg every other day was sufficient in 9 of 23 (39%) of responders and was associated with less neuropathy and longer treatment duration. CONCLUSIONS AND RELEVANCE: In this cohort study, second-line therapy with thalidomide was associated with complete remission in two-thirds of the 35 patients with chronic EM. However, adverse events were a common cause of thalidomide withdrawal. In the long term, dose reduction when possible may allow for continuation by improving tolerance.

Benefit/risk Ratio of Low-dose Methotrexate in Cutaneous Lesions of Mycosis Fungoides and Sézary Syndrome.

Low-dose methotrexate is widely used in mycosis fungoides and Sézary syndrome, but few studies have evaluated this treatment. The aim of this study was to evaluate the benefit/risk ratio of this regimen on skin lesions. A retrospective survey of a series of patients treated for mycosis fungoides or Sézary syndrome with low-dose methotrexate and followed for at least one year in a tertiary referral centre was performed. From a total of 48 patients, complete response and partial response were achieved in 10 (21%) and 25 (52%) patients, respectively, with no significant difference in response rates between mycosis fungoides and Sézary syndrome. Of the responders, 20 out of 35 (57%) relapsed after a median time of 11 months. Forty-four of the total of 48 patients discontinued methotrexate, mainly due to primary or secondary failure and/or limiting toxicity (9 patients). Overall, the benefit/risk ratio of low-dose methotrexate in mycosis fungoides and Sézary syndrome appears favorable and this treat-ment remains a valid option in mycosis fungoides/Sézary syndrome. However, its activity is limited in duration and significant toxicity may occur in some patients.

Decision Tree Learning Algorithm for Classifying Knee Injury Status Using Return-to-Activity Criteria.

Anterior cruciate ligament (ACL) injury rates in female adolescents are increasing. Irrespective of treatment options, approximately 1/3 will suffer secondary ACL injuries following their return to activity (RTA). Despite this, there are no evidence-informed RTA guidelines to aid clinicians in deciding when this should occur. The first step towards these guidelines is to identify relevant and feasible measures to assess the functional status of these patients. The purpose of this study was therefore to evaluate tests frequently used to assess functional capacity following surgery using a Reduced Error Pruning Tree (REPT). Thirty-six healthy and forty-two ACLinjured adolescent females performed a series of functional tasks. Motion analysis along with spatiotemporal measures were used to extract thirty clinically relevant variables. The REPT reduced these variables down to two limb symmetry measures (maximum anterior hop and maximum lateral hop), capable of classifying injury status between the healthy and ACL injured participants with a 69% sensitivity, 78% specificity and kappa statistic of 0.464. We, therefore, conclude that the REPT model was able to evaluate functional capacity as it relates to injury status in adolescent females. We also recommend considering these variables when developing RTA assessments and guidelines.Clinical Relevance- Our results indicate that spatiotemporal measures may differentiate ACL-injured and healthy female adolescents with moderate confidence using a REPT. The identified tests may reasonably be added to the clinical evaluation process when evaluating functional capacity and readiness to return to activity.

Hemophagocytic lymphohistiocytosis in advanced melanoma treated with dabrafenib and trametinib combination: two cases.

Hemophagocytic lymphohistiocytosis (HLH) has been only rarely reported in patients with BRAF-mutated advanced melanoma treated with targeted therapies and never with first-line dabrafenib/trametinib combination thus far. Two patients treated with first-line dabrafenib and trametinib combination therapy for metastatic melanoma presented with sudden occurrence of fever, cytopenia, rhabdomyolysis, hepatic cytolysis, hypertriglyceridemia and very high ferritin levels after few weeks of treatment, associated with concomitant epstein-barr virus (EBV) reactivation in one patient. In both cases, drug-induced HLH was primarily considered owing to a high H-score and the absence of other etiology. Patients rapidly improved after treatment discontinuation associated with oral steroids in one patient and did not relapse after subsequent treatment resumption with a concurrent anti-BRAF/anti-MEK combination. In metastatic melanoma HLH may occur either spontaneously in the absence of any treatment as a paraneoplastic condition, related to an intercurrent infection or drug-induced mainly with various immunotherapy or with dabrafenib and trametinib following immunotherapy. However, such observations are scarce and these are the first cases of HLH occurring during first-line treatment with dabrafenib and trametinib in advanced melanoma to our knowledge. Pathomechanisms remain to be elucidated since triggering factors may encompass the treatment itself but also other significant actors including viral reactivation along with the underlying disease. The liability of treatment should be considered in cases of HLH occurring in patients with advanced melanoma successfully treated with a combined targeted therapy. A rechallenge with a concurrent anti-BRAF/anti-MEK can be proposed in this setting.

Delayed diagnosis and inappropriate clinical management of nicorandil-induced oral lesions: A case report.

Oral ulcers have a number of causes, and as a result, their etiology can be difficult to determine. Clinical management can range from simple treatment of the symptoms to extensive surgical excision, as in the case of malignant ulcers. Nicorandil, an antiangina drug, has been identified as a potential trigger for cutaneomucosal ulcers. This article reviews the importance of taking a full medical history when seeking to identify the side effects of treatments. We present the case of a 70-year-old patient with chronic ulceration of the oral mucosa. Determining the cause of ulceration as a side effect of taking nicorandil was delayed because the team that initially managed the patient hypothesized a malignant etiology. As a result, a partial glossectomy was performed for diagnostic and therapeutic purposes. After extensive examination of the patient's medical history and current treatments, nicorandil was identified as the potential trigger. The patient finally recovered after discontinuation of nicorandil.

Tolerance of Douglas Fir Somatic Plantlets to Aluminum Stress: Biological, Cytological, and Mineral Studies.

Aluminum (Al) is well known as a potent inhibitor of plant growth and development. It is notably present in soils in the soluble and bioavailable form Al3+ when the soil pH drops below 5. This situation is frequent, especially in softwood forests when litter decomposition is slow. In the present work, we studied the effects of Al3+ on the growth and development of Douglas fir plantlets. Somatic plantlets, regenerated via somatic embryogenesis, were grown in vitro on media supplemented with different concentrations of aluminum chloride (AlCl3): 0 µM, 200 µM, 500 µM. and 1 mM. We show that a concentration of 500 µM AlCl3 in medium significantly reduced root elongation (-21.8%), as well as stem growth (-14.6%). Also, a 25% reduction in dry mass of the plantlets was observed in presence of a concentration of 200 µM of AlCl3. Histological analysis of root tissues revealed significant damage, especially in conducting vessels. In addition, mineral cation content of plantlets was disturbed under Al exposure. More particularly, the Mg and K contents of needles and the Ca content of stems and needles were significantly reduced in presence of a concentration of 500 µM AlCl3 in the culture medium (-35.6%, -33.5%, -24%, and -34% respectively). However, all these damages appeared at relatively high Al concentrations when compared with other herbaceous species. This study shed light on the ability of Douglas fir in vitro plantlets to cope with the acid-driven toxicity of Al.

Use of a Pleurotus ostreatus Complex Cell Wall Extract as Elicitor of Plant Defenses: From Greenhouse to Field Trial.

Fungi constitute an abundant source of natural polysaccharides, some of them harboring original structures which can induce responses in mammalian or plant cells. An alkaline extract from the edible mushroom Pleurotus ostreatus has been obtained and called Pleuran complex cell wall extract (CCWE). It consists of a glucan-peptide complex whose components fall in a quite broad range of molecular weights, from 30 to 80 kDa. Pleuran extract has been tested on cultivated plants in laboratory conditions and also during field trial for its capacity to stimulate plant defenses in response to pathogen attack. Following Pleuran CCWE treatment, enhanced levels of various biochemical markers associated with plant responses have been observed, including enzymatic activities (e.g., peroxidase) or expression of some pathogenesis-related genes. In addition, during field experiments, we have noticed significant reductions in disease symptom levels in relation to different plant/pathogen systems (wheat/septoria, vine/mildew). These results confirmed that Pleuran CCWE could be used as an elicitor of plant defenses and could help in reducing pesticide applications against plant pathogens.
