Abstract Background Papillary oral pathologies are a heterogenous group. Both virus-associated and non-virus-associated, malignant and benign entities may enter the differential diagnosis. In some cases, oral papillary lesions are part of a variety of skin or systemic disorders and syndromes. It is a challenge for clinicians to identify and treat the various etiology of oral papillary lesions. Case presentation This case report describes the successful management of large multiple oral papillary lesions in a 65-year-old female. Combined the clinical features, pathological findings and medical history, the patient was tended to be the diagnosis of Acanthosis Nigricans and was successfully managed. The neuro-endocrine-immune network and mechanical factors in the pathogenesis of oral papillary lesions of Acanthosis Nigricans were discussed. Common questions regarding differential diagnosis, the management of oral papillary lesions of Acanthosis Nigricans patients and follow-up visits are addressed. Conclusions The neuro-endocrine-immune network and mechanical factors play important roles in the pathogenesis of oral papillary lesions with Acanthosis Nigricans. Removing traumatic factors of oral mucosa and the treatment of underlying systemic diseases is necessary for Acanthosis Nigricans patients with oral papillary lesions. The clinical management plan should comprise both the local treatments of oral papillary lesions and the systemic treatment of underlying diseases. Multidisciplinary correlation is helpful and the patient’s collaboration is necessary to arrive at the correct diagnosis and successful long-term treatment effect. From the clinician’s perspective, recognizing various causes and clinical presentations of oral papillary lesions will help guide management.

Hexanucleotide G4C2 repeat expansions in the C9ORF72 gene are the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Dipeptide repeat proteins (DPRs) generated by translation of repeat-containing RNAs show toxic effects in vivo as well as in vitro and are key targets for therapeutic intervention. We generated human antibodies that bind DPRs with high affinity and specificity. Anti-GA antibodies engaged extra- and intracellular poly-GA and reduced aggregate formation in a poly-GA over-expressing human cell line. However, antibody treatment in human neuronal cultures synthesizing exogenous poly-GA resulted in the formation of large extracellular immune complexes and did not affect accumulation of intracellular poly-GA aggregates. Treatment with antibodies was also shown to directly alter the morphological and biochemical properties of poly-GA and to shift poly-GA/antibody complexes to more rapidly sedimenting ones. These alterations were not observed with poly-GP and have important implications for accurate measurement of poly-GA levels including the need to evaluate all centrifugation fractions and disrupt the interaction between treatment antibodies and poly-GA by denaturation. Targeting poly-GA and poly-GP in two mouse models expressing G4C2 repeats by systemic antibody delivery for up to 16 months was well-tolerated and led to measurable brain penetration of antibodies. Long term treatment with anti-GA antibodies produced improvement in an open field movement test in aged C9ORF72450 mice. However, chronic administration of anti-GA antibodies in AAV-(G4C2)149 mice was associated with increased levels of poly-GA detected by immunoassay and did not significantly reduce poly-GA aggregates or alleviate disease progression in this model.

Gout is a common form of inflammatory arthritis where urate crystals deposit in joints and surrounding tissues. With the high prevalence of gout, the standardized and effective treatment of gout is very important, but the long-term treatment effect of gout is not satisfied because of the poor adherence in patients to the medicines. Recently, advanced imaging modalities, including ultrasonography (US), dual-energy computed tomography (DECT), and magnetic resonance imaging (MRI), attracted more and more attention for their role on gout as intuitive and non-invasive tools for early gout diagnosis and evaluation of therapeutic effect. This review summarized the role of US, DECT, and MRI in the management of gout from four perspectives: hyperuricemia, gout attacks, chronic gout, and gout complications described the scoring systems currently used to quantify disease severity and discussed the challenges and limitations of using these imaging tools to assess response to the gout treatment.

Bipolar disorder (BD) displays abnormalities in protein kinase C (PKC) signaling, and evidence suggests that inhibiting PKC may help treat mania. Endoxifen a potent inhibitor of the PKC signaling pathway, is effective in controlling acute bipolar mania, at doses of 8 mg OD, for a period of 3-weeks. Here we present the case of a patient with severe mania, increased alcohol consumption administered endoxifen 8 mg BID for a period of 3-months, to achieve a better response. High-dose, long-term treatment with endoxifen was efficacious in controlling manic symptoms, with no adverse effects. Additionally, the patient didn’t consume alcohol during the course of treatment. This case showed the long-term effectiveness and safety of high-dose endoxifen to control mania in a patient with BD.

Chitosan is a well-known subjectof researchbecause of its beneficial properties, including its antibacterial and fungicidal activity, as well as its effect on plant physiology. One of the maindifficulties in agricultural chitosan implementation is the poor solubility of high molecular chitosan in water. Reducing themolecular weight of chitosan by acid hydrolysis increases its solubility. This research studied the effect of chitosan hydrolysate on the germination and development ofSolanum lycopersicum L. plants. Theeffects of chitosan hydrolysate on seed germination, shoot development in the first week of development and in the first month of development were evaluated. According to the results, high concentrations of chitosan hydrolysate completely inhibited seed germination. However, short-term treatment by high concentrations of chitosan hydrolysate stimulatedthe development of seedlings, leading to substantially longerroots. Regular root application of high concentrations of chitosan hydrolysate inhibited plant development. Keywords: chitosan hydrolysate, chitosan, plant growth regulators, plant germination

Background: Clinical presentations and treatment programs about anti-leucine-rich glioma inactivated 1 (LGI1) encephalitis still remain incompletely understood.Objective: This study analyzed the clinical features and therapeutic effects of anti-LGI1 encephalitis.Methods: PubMed, EMBASE, and the Cochrane Library were searched to identify published English and Chinese articles until April 2021. Data were extracted, analyzed, and recorded in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines.Results: A total of 80 publications detailing 485 subjects matched our inclusion criteria. Short-term memory loss (75.22%), faciobrachial dystonic seizures (FBDS) (52.53%), other seizures excluding FBDS (68.48%), psychiatric symptoms (57.67%), and sleep disturbances (34.30%) were the most frequently described symptoms in anti-LGI1 encephalitis. Hyponatremia (54.90%) was the most common hematologic examination change. The risk of incidence rate of malignant tumors was higher than in healthy people. The positive rate of anti-LGI1 in serum (99.79%) was higher than CSF (77.38%). Steroids (93.02%), IVIG (87.50%), and combined use (96.67%) all had a high remission rate in the initial visit. A total of 35 of 215 cases relapsed, of which 6/35 (17.14%) did not use first-line treatment, and 21 (60.00%) did not maintain long-term treatment. Plasma exchange (PE) could be combined in severe patients, immunosuppressant could be used for refractory patients or for recurrence and using an anti-epileptic drug to control seizures may benefit cognition.Conclusions: Short-term memory loss, FBDS, psychiatric symptoms, and hyponatremia were key features in identifying anti-LGI1 encephalitis. Serum and CSF antibody tests should be considered in diagnosis criteria. Steroids with IVIG should be recommended, PE was combined for use in severe patients, immunosuppressant therapy might improve outcomes if recurrence or progression occurred, and control seizures might benefit cognition. The useful ways to reduce relapse rate were early identification, clear diagnosis, rapid treatment, and maintaining long-term treatment. The follow-up advice was suggested according to the research of paraneoplastic syndrome, and concern about tumors was vital as well.

Background: Short-term effects of alirocumab on vascular function have hardly been investigated. Moreover, there is a scarce of reliable non-invasive methods to evaluate atherosclerotic changes of the vasculature. The ALIROCKS trial was performed to address these issues using standard ultrasound-based procedures and a completely novel magnetic resonance-based imaging technique. Methods: A total of 24 patients with an indication for treatment with PCSK9 antibodies were recruited. There were 2 visits to the study site, the first before initiation of treatment with alirocumab and the second after 10 weeks of treatment. The key outcome measures included the change of carotid vessel wall fractional anisotropy, a novel magnetic resonance-based measure of vascular integrity, and the changes of carotid intima-media thickness and flow-dependent dilatation of the brachial artery measured with ultrasound. Results: A total of 19 patients completed the trial, 2 patients stopped treatment, 3 patients did not undergo the second visit due to the COVID pandemic. All of them had atherosclerotic vascular disease. Their mean (standard deviation) LDL-cholesterol concentration was 154 (85) mg/dL at baseline and was reduced by 76 (44) mg/dL in response to alirocumab treatment (p < 0.001, n = 19). P-selectin and vascular endothelial growth factors remained unchanged. Flow-dependent dilatation of the brachial artery (+41%, p = 0.241, n = 18), carotid intima-media thickness (p = 0.914, n = 18), and fractional anisotropy of the carotid artery (p = 0.358, n = 13) also did not significantly change. Conclusion: Despite a nominal amelioration for flow-dependent dilatation, significant effects of short-term treatment with alirocumab on vascular function were not detectable. More work would be needed to evaluate, whether fractional anisotropy may be useful in clinical atherosclerosis research.

Objective: Magnetic stimulation (MS) provides a novel strategy for the treatment of urinary incontinence (UI), although its efficacy remains uncertain. This systematic review both evaluated the effects of MS treatment on UI and investigated its impacts on female patients’ life quality. Methods: A review of the literature that was conducted in EMBASE, PubMed, Google Scholar, and the Cochrane Library (2016–2021) with the search terms; Incontinence of stress OR urge of urination OR Urinary incontinence mixed type. The search was carried out for all randomised controlled trials (RCTs) in English. A manual search has also been conducted for the reference lists of the studies found. Seven studies, with a total of 523 patients (475 patients with SUI), 12 urge urinary incontinence. The study included patients with (UUI) and 36 patients with mixed urinary incontinence (MUI). A total of 10 male patients were excluded from the study. In the included studies, The International Incontinence Questionnaire-Short Form was used to investigate the effects of MS therapy on UI symptoms (ICIQ-SF). Results: According to the literature review, MS is an effective therapy option for female patients with UI. Still, to establish the efficacy of MS in this area, more large-scale, high-quality RCTs with extended follow-up periods that use consistent stimulation modalities and evaluate comparable outcomes are needed. Conclusion: MS treatment leads to an improvement in the symptoms of UI, in addition to an associated Improved quality of life for patients, without any reported side effects, while the longer-term treatment outcomes must be determined by long-term trials.

CADTH recommends that Opsynvi should be reimbursed by public drug plans for the long-term treatment of pulmonary arterial hypertension (PAH; WHO Group 1) to reduce morbidity in patients in WHO functional class (FC) II or III whose PAH is idiopathic, heritable, or associated with connective tissue disease or congenital heart disease if certain conditions are met. Opsynvi should only be covered for patients who are currently treated simultaneously with stable doses of macitentan 10 mg and tadalafil 40 mg as separate tablets. Opsynvi should only be reimbursed if prescribed by a specialist with expertise in managing and treating patients with PAH and if the price of Opsynvi is negotiated to ensure cost savings in comparison with separate macitentan and tadalafil tablets.
