Autonomic rehabilitation: Vagal and sympathetic impacts of modified occipitomastoid suture V-spread.

Autonomic rehabilitation using osteopathic manipulative treatment (OMT) to stimulate the vagus nerve may be a good adjunct therapy by physiatrists who treat dysautonomia. Heart rate variability (HRV) may provide quantitative evidence for the benefits of OMT on autonomic nervous system function. Elevated HRV indicates optimal health and reduced mortality risk, whereas low HRV is associated with stress, pain, and chronic disease pathology. To analyze the impact of modified occipitomastoid suture v-spread OMT technique on vagal tone by measuring HRV. Within-participant design with 5-minute HRV measurement pre- and post-OMT treatment. Clinical examination suites. Thirty healthy osteopathic medical students. A modified occipitomastoid suture v-spread treating somatic dysfunction by osteopathic physicians trained in osteopathic neuromusculoskeletal medicine. HRV variables related to vagal tone including root mean square of successive differences (RMSSD), percentage of successive normal sinus RR intervals >50 ms (pNN50), high frequency (HF), Parasympathetic Nervous System Index (PNSI), and Sympathetic Nervous System Index (SNSI). Repeated measures t-test analyzed the difference in mean HRV values after OMT. There were statistically significant increases in each of the HRV measures after OMT. Participants had a mean (95% confidence interval) RMSSD of 50.5 ms (38.3-62.8) at baseline and 55.0 ms (41.2-68.7, p = .013) post-OMT. pNN50 was 24.5% (17.6-31.3, n = 30) at baseline and 28.2% (20.8-35.6, p = .003) post-OMT. HF was 1549.6 ms2 (389.8-2709.4) at baseline and 1901.8 ms2 (618.2-3185.4, p = .103) post-OMT. PNSI was -0.1 (-0.5 to 0.2) at baseline and 0.1 (-0.3 to 1.5, p < .01) post-OMT, and SNSI was 0.2 (-0.1 to 0.6) at baseline and 0.05 (-0.3 to 0.4, p < .01) post-OMT. Normalization, due to high baseline variance, results include RMSSD 1.1 ms (1.0 to 1.1, p = .012), pNN50 1.3 (1.1 to 1.4, p = .011), and HF 1.2 ms2 (1.1 to 1.4, p = .018). Modified occipitomastoid suture v-spread may provide clinical benefit through increased vagal tone and decreased sympathetic activity.

Effect of aspirin on platelet-rich plasma of diabetes mellitus with lower extremity atherosclerosis.

Aim: Platelet-rich plasma (PRP), enriched with multiple growth factors, is a promising adjunctive therapy for diabetic foot ulcers (DFUs). As a classic anti-platelet drug for diabetic patients, the effects of aspirin on the content of growth factors in PRP remains unclear.Methods: Our study enrolled diabetic patients who were currently taking or not taking aspirin as the research subjects, with healthy volunteers as the control. PRP from these individuals was activated with glucose calcium and thrombin. Growth factors levels in PRP activated supernatant (PRP-AS) and wound healing ability of platelet gel (PG) in the full-thickness skin defect diabetic mouse model were compared.Results: We found the level of growth factors in PRP-AS derived from two groups of diabetic patients were not statistically different, whereas both lower than that from healthy volunteers. Similarly, we found better wound healing ability of PG from healthy volunteers than those from diabetic patients, but no difference between the two groups of diabetic patients in the mouse model.Discussion: Aspirin does not interfere with autologous PRP therapy when using calcium gluconate and thrombin as agonists. However considering the content of growth factors, PRP from healthy volunteers is a preferable option for promoting DFU repair.

The renoprotective efficacy and safety of genetically-engineered human bone marrow-derived mesenchymal stromal cells expressing anti-fibrotic cargo

BackgroundKidney fibrosis is a hallmark of chronic kidney disease (CKD) and compromises the viability of transplanted human bone marrow-derived mesenchymal stromal cells (BM-MSCs). Hence, BM-MSCs were genetically-engineered to express the anti-fibrotic and renoprotective hormone, human relaxin-2 (RLX) and green fluorescent protein (BM-MSCs-eRLX + GFP), which enabled BM-MSCs-eRLX + GFP delivery via a single intravenous injection.MethodsBM-MSCs were lentiviral-transduced with human relaxin-2 cDNA and GFP, under a eukaryotic translation elongation factor-1α promoter (BM-MSCs-eRLX + GFP) or GFP alone (BM-MSCs-eGFP). The ability of BM-MSCs-eRLX + GFP to differentiate, proliferate, migrate, produce RLX and cytokines was evaluated in vitro, whilst BM-MSC-eRLX + GFP vs BM-MSCs-eGFP homing to the injured kidney and renoprotective effects were evaluated in preclinical models of ischemia reperfusion injury (IRI) and high salt (HS)-induced hypertensive CKD in vivo. The long-term safety of BM-MSCs-RLX + GFP was also determined 9-months after treatment cessation in vivo.ResultsWhen cultured for 3- or 7-days in vitro, 1 × 106 BM-MSCs-eRLX + GFP produced therapeutic RLX levels, and secreted an enhanced but finely-tuned cytokine profile without compromising their proliferation or differentiation capacity compared to naïve BM-MSCs. BM-MSCs-eRLX + GFP were identified in the kidney 2-weeks post-administration and retained the therapeutic effects of RLX in vivo. 1–2 × 106 BM-MSCs-eRLX + GFP attenuated the IRI- or therapeutically abrogated the HS-induced tubular epithelial damage and interstitial fibrosis, and significantly reduced the HS-induced hypertension, glomerulosclerosis and proteinuria. This was to an equivalent extent as RLX and BM-MSCs administered separately but to a broader extent than BM-MSCs-eGFP or the angiotensin-converting enzyme inhibitor, perindopril. Additionally, these renoprotective effects of BM-MSCs-eRLX + GFP were maintained in the presence of perindopril co-treatment, highlighting their suitability as adjunct therapies to ACE inhibition. Importantly, no major long-term adverse effects of BM-MSCs-eRLX + GFP were observed.ConclusionsBM-MSCs-eRLX + GFP produced greater renoprotective and therapeutic efficacy over that of BM-MSCs-eGFP or ACE inhibition, and may represent a novel and safe treatment option for acute kidney injury and hypertensive CKD.

Transforming lives in autism spectrum disorder treatment through acupuncture: A case report

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication, restricted and repetitive behaviors, and narrow interests. Given the high prevalence of ASD and the lack of specific pharmacological treatments, there is a pressing need for alternative therapeutic approaches. Acupuncture has shown promise in improving the clinical symptoms of ASD. This report presents the case of a 6-year-old girl diagnosed with ASD, intellectual developmental disorder, attention deficit hyperactivity disorder, and articulation disorder. She underwent Liu&amp;rsquo;s pediatric neurological rehabilitation acupuncture therapy (PNRAT) for over 2 years. The treatment involved specific scalp acupuncture techniques targeting cognitive and linguistic rehabilitation. After the treatment course, the patient showed significant improvements in cognitive, linguistic, social, and behavioral symptoms, transitioning from limited verbal communication and marked social difficulties to thriving in a mainstream school setting. This case highlights the potential of Liu&amp;rsquo;s PNRAT as an effective intervention for ASD. The observed improvements suggest that acupuncture may offer valuable therapeutic benefits for children with ASD, contributing to the growing interest in its potential as an adjunct therapy. Further research is needed to optimize treatment protocols and explore synergies with conventional therapies.

The Analysis Study of Effect of Acupuncture on the Treatment of Atopic Itch: A Comprehensive Systematic Review

Background: Atopic dermatitis is a common inflammatory skin disorder characterized by recurrent eczematous lesions and severe itching. Given its chronic nature and association with persistent pruritus, exploring therapies like acupuncture may offer valuable relief and enhance patient outcomes. This systematic review aims to explore the efficacy and mechanisms of acupuncture as a treatment for atopic pruritus based on the literature of the last decade. Methods: The study followed PRISMA 2020 guidelines, reviewing English-language publications from 2014 to 2024. Editorials, duplicate reviews from the same journal, and papers lacking a DOI were excluded. The literature search was conducted using PubMed, SagePub, SpringerLink, and Google Scholar. Result: A total of 630 articles were initially identified through online databases (PubMed, SagePub, SpringerLink, and Google Scholar). After three rounds of screening, eight relevant studies were selected for full-text analysis. Conclusion: Acupuncture shows potential as a noninvasive and effective treatment for reducing pruritus and associated symptoms in patients with atopic dermatitis and other pruritic conditions. The observed benefits, such as decreased itch intensity, improved quality of life, and reduced medication use, underline its value as an adjunct therapy.

Efficacy and Safety of Intrapleural Fibrinolytic Therapy in Empyema Thoracis: A Meta-Analysis of Clinical Outcomes

Background: Empyema thoracis is a severe pulmonary condition characterized by pus accumulation in the pleural space. Intrapleural fibrinolytic therapy is used adjunctively to break down loculations and facilitate lung re-expansion. This meta-analysis evaluated the efficacy and safety of this treatment in adults with empyema thoracis. Methods: A systematic search of PubMed, Embase, and Cochrane Central Register of Controlled Trials was conducted (January 2013 - December 2023) for randomized controlled trials (RCTs) comparing intrapleural fibrinolytics with placebo or no fibrinolytic therapy in adults with empyema. Primary outcomes were treatment success (radiographic improvement and/or clinical resolution), duration of hospital stay, and mortality. Secondary outcomes included major bleeding and bronchopleural fistula. Data were pooled using a random-effects model, and risk ratios (RR) or mean differences (MD) with 95% confidence intervals (CI) were calculated. Results: Six RCTs (n=623 patients) met the inclusion criteria. Intrapleural fibrinolytic therapy showed a significantly higher treatment success rate than the control (RR 1.42, 95% CI 1.18-1.72, p=0.001) and significantly reduced hospital stay (MD -2.84 days, 95% CI -3.36 to -2.33, p&lt;0.001). No significant difference in mortality was found (RR 0.95, 95% CI 0.46-1.93, p=0.93). The incidence of major bleeding and bronchopleural fistula was similar between the groups. Conclusion: Intrapleural fibrinolytic therapy significantly improves treatment success and reduces hospital stays without increasing mortality or major complications. These findings support its use as an adjunctive therapy for drainage in managing empyema thoracis in adults.

The Therapeutic Potential of GLP-1 Receptor Agonists in the Management of Hidradenitis Suppurativa: A Systematic Review of Anti-Inflammatory and Metabolic Effects

Background: Glucagon-like peptide-1 receptor agonists (GLP1-RAs) are synthetic peptides that mimic the natural activity of GLP-1, widely known for lowering blood glucose levels and promoting weight reduction. These characteristics make them a valuable tool in managing type 2 diabetes and obesity-related conditions. Recent findings indicate that GLP1-RAs may also offer therapeutic benefits in managing hidradenitis suppurativa (HS), a chronic inflammatory skin disorder closely associated with metabolic abnormalities, including obesity, diabetes, and dyslipidemia. This review explores the potential role of GLP1-RAs in managing HS. Methods: A systematic review was conducted by searching electronic databases, including MEDLINE and Google Scholar, without date limitations. Key search terms included “GLP-1” or “GLP-1 agonists” combined with “hidradenitis suppurativa” or “acne inversa”. Inclusion criteria were set for studies reporting on the use of GLP1-RAs as a treatment for HS, with articles discussing theoretical applications excluded. Data synthesis included findings from 25 relevant studies. Results: The analysis revealed that GLP1-RAs, specifically liraglutide and semaglutide, led to significant reductions in weight and systemic inflammation in HS patients. Notably, improvements in lesion severity and quality of life were reported. The anti-inflammatory effects of GLP1-RAs were attributed to the suppression of key inflammatory pathways involving TNF-α, IL-17, and NF-κB. Conclusions: GLP1-RAs demonstrate significant potential as an adjunct therapy for HS, addressing both the metabolic and inflammatory aspects of the condition. While early results are promising, further research is necessary to determine their long-term efficacy in managing HS.

Propolis Extract Attenuates NF-κB Activation and Chronic Kidney Disease Progression in a Rat Model: Potential Surgical Adjuvant?

Background: Chronic kidney disease (CKD) is a global health concern often complicated by cardiovascular diseases like atherosclerosis. Both conditions share an inflammatory pathogenesis, with nuclear factor kappa B (NF-κB) playing a central role. Propolis, a natural bee product with anti-inflammatory properties, has shown potential in mitigating CKD progression. This study aimed to investigate the effects of propolis extract on NF-κB activation in a rat model of CKD, exploring its potential benefits as a surgical adjuvant. Methods: Male white rats (Rattus norvegicus) were divided into three groups: a control group, a CKD group, and a CKD+Propolis group receiving propolis extract (200 mg/kg body weight) daily for 20 days. CKD was induced using the unilateral ureteral obstruction (UUO) method. NF-κB levels were measured weekly using ELISA. Results: Propolis extract significantly reduced NF-κB levels in the CKD+Propolis group compared to the CKD group (p&lt;0.05). This effect was consistently observed across all time points, indicating a sustained reduction in NF-κB activation with propolis treatment. Conclusion: Propolis extract effectively attenuates NF-κB activation in a rat model of CKD, suggesting its potential as an adjunctive therapy for CKD management, particularly in the context of surgical interventions. Further research is needed to elucidate the underlying mechanisms and evaluate its efficacy in human subjects.

The Paradise Renal Denervation System: An FDA-approved catheter-based treatment option for resistant hypertension

Resistant hypertension is defined as office blood pressure &gt;140/90 mm Hg with a mean 24-hour ambulatory blood pressure of &gt;130/80 mm Hg in patients who are compliant with 3 or more antihypertensive medications. Those who persistently fail pharmaceutical therapy may benefit from interventional treatment, such as renal denervation. Sympathetic nervous activity in the kidney is a known contributor to increased blood pressure because it results in efferent and afferent arteriole vasoconstriction, reduced renal blood flow, increased sodium and water reabsorption, and the release of renin. The Recor Paradise Renal Denervation System is designed to target renal sympathetic nerves via ultrasound ablation. The RADIANCE trials have demonstrated that patients who underwent renal denervation had a significant decrease in systolic blood pressure as compared with those who underwent a sham procedure. Furthermore, the device was found to have a favorable safety profile, with minimal major adverse events. The Food and Drug Administration granted approval to Recor, and the Paradise system is expected to serve as an adjunctive therapy for patients with true-resistant hypertension.

The Potential Role of Polyphenol Supplementation in Preventing and Managing Depression: A Review of Current Research

Depression is a common mental illness that affects 5% of the adult population globally. The most common symptoms of depression are low mood, lack of pleasure from different activities, poor concentration, and reduced energy levels for an extended period, and it affects the emotions, behaviors, and overall well-being of an individual. The complex pathophysiology of depression presents challenges for current therapeutic options involving a biopsychosocial treatment plan. These treatments may have a delayed onset, low remission and response rates, and undesirable side effects. Researchers in nutrition and food science are increasingly addressing depression, which is a significant public health concern due to the association of depression with the increased incidence of cardiovascular diseases and premature mortality. Polyphenols present in our diet may significantly impact the prevention and treatment of depression. The primary mechanisms include reducing inflammation and oxidative stress, regulating monoamine neurotransmitter levels, and modulating the microbiota–gut–brain axis and hyperactivity of the hypothalamic–pituitary–adrenal (HPA) axis. This review summarizes recent advances in understanding the effects of dietary polyphenols on depression and explores the underlying mechanisms of these effects for the benefit of human health. It also highlights studies that are looking at clinical trials to help future researchers incorporate these substances into functional diets, nutritional supplements, or adjunctive therapy to prevent and treat depression.

Facile minocycline deployment in gingiva using a dissolvable microneedle patch for the adjunctive treatment of periodontal disease

AbstractMinocycline is a commonly used drug for adjunctive therapy in periodontal disease. However, the current mainstream local medications primarily rely on intra‐pocket administration, which, while avoiding the side effects of traditional systemic drugs, presents challenges such as inconvenience, discomfort, and the need for professional assistance, thus affecting patient compliance. Herein, we introduce a minocycline‐loaded dissolvable microneedle (Mino‐DMN) patch that allows for local and efficient delivery of minocycline to gingiva for the treatment of periodontitis. A two‐step casting micro‐molding process involving vacuum drying and freeze drying is employed to concentrate minocycline in the microneedle part and limit its diffusion into the patch backing. The resulting Mino‐DMN patch features an array of minocycline‐enriched gelatin MNs with a porous HA patch backing. The microneedles can penetrate into gingiva with enough mechanical strength and quickly release minocycline into the gingival tissue, ensuring prolonged local residence of the drug and minimizing its loss to saliva. In vivo experiments show Mino‐DMN inhibits pro‐inflammatory factors, promotes anti‐inflammatory factors, and stimulates bone formation, surpassing topical application and comparable to the inconvenient and discomfort administration of Periocline®. This proposed Mino‐DMN offers a simple, efficient, user‐friendly strategy for the adjunctive treatment of periodontal disease.

Effectiveness of a 12-week combining tai chi and yoga program on pulmonary function and functional fitness in COPD patients

BackgroundChronic obstructive pulmonary disease (COPD) poses significant challenges to both patients and healthcare providers due to its progressive nature and adverse impact on respiratory function and quality of life (QoL). While pulmonary rehabilitation remains a cornerstone of non-pharmacological COPD management, additional interventions are needed to address patients' diverse needs and preferences. AimThis study investigated the feasibility and potential benefits of a 12-week combining Tai Chi and Yoga (TY combining) program on cardiorespiratory and lung functions, functional fitness, and QoL in older males diagnosed with COPD. MethodsTwenty-four male COPD patients (age: 70 ± 6 years) with moderate to severe disease were recruited and randomized into the TY combining group (n = 12) or control group (n = 12). Assessments were conducted at baseline and at week 12, including pulmonary function tests, quality of life measures, dyspnea, and fatigue. Functional fitness tests were assessed at baseline, week 4, week 8, and week 12. ResultsThe TY combining program significantly improved pulmonary functions, functional fitness, quality of life, and fatigue over the 12-week intervention period. Notably, improvements in functional fitness parameters were observed after just four weeks of training, emphasizing the rapid benefits of the intervention. Moreover, the program exhibited high safety and feasibility, with no reported complications. ConclusionThe 12-week TY combining program represents a safe, feasible, and effective adjunctive therapy for COPD management in older male patients. By addressing multiple dimensions of health and functioning, including pulmonary and cardiovascular health, functional fitness, and quality of life, this holistic approach holds promise for optimizing outcomes in COPD patients. Further research is warranted to validate these findings and explore optimal implementation strategies in clinical practice.

Comparative Study of Photobiomodulation Effects on Alveolar Socket Hard Tissue Healing in Rats: Application of 980 nm Versus 810 nm Lasers.

Background: This study aimed to explore the differential effects of photobiomodulation (PBM) via 980 nm and 810 nm lasers on the hard tissue healing of rat alveolar sockets, with a focus on a comparative analysis of hard tissue regeneration and osteogenic gene expression. Objective: This study aimed to explore the effects of PBM using 980 nm and 810 nm lasers on hard tissue healing of rat alveolar sockets, focusing on hard tissue regeneration and osteogenic gene expression. Materials and Methods: Thirty-six male Wistar rats (5 weeks old) had both right and left maxillary first molars extracted. Post extraction, the right alveolar sockets received PBM treatment with either 980 nm (0.3 W, 18 J/cm2) or 810 nm (0.1 W, 6 J/cm2) lasers for seven days, whereas the left sockets served as controls. Rats were euthanized on days 3, 7, 14, and 28 for histopathological, immunohistochemical, micro computed tomography (micro-CT), and quantitative polymerase chain reactionanalyses. Results: On day 3, early granulation tissue, neovascularization, and inflammatory cell aggregates were observed in all groups. By day 7, active osteoclasts and osteoblasts were noted, with a significant increase in CD31-positive cells in the 980 nm group (p < 0.05). Day 14 showed new bone formation, and by day 28, increased cancellous bone and collagen content were present in all groups, with no significant differences between them (p > 0.05). Gene expression analysis revealed higher BMP-2 and Runx-2 levels in laser-treated groups on day 14 (p < 0.05), with the 980 nm group having higher BMP-2 levels than the 810 nm group (p < 0.05). Bone sialoprotein expression was higher in laser-treated groups on days 14 and 28 (p < 0.05), and osteocalcin expression was highest in the 980 nm group on both days (p < 0.05). Micro-CT analysis showed no significant differences among groups in bone mineral density, bone surface (BS)/bone volume (BV), or bone volume (BV)/TV (total volume) indices. Conclusion: PBM with 980 nm and 810 nm lasers promotes early-stage hard tissue healing in extraction sockets, with the 980 nm laser more effectively enhancing osteogenic gene expression, suggesting its potential as an adjunctive therapy in dental and oral surgery.

Targeting the Renin-angiotensin-aldosterone System (RAAS) for Cardiovascular Protection and Enhanced Oncological Outcomes: Review.

The renin-angiotensin-aldosterone system (RAAS) is a crucial regulator of the cardiovascular system and a target for widely used therapeutic drugs. Dysregulation of RAAS, implicated in prevalent diseases like hypertension and heart failure, has recently gained attention in oncological contexts due to its role in tumor biology and cardiovascular toxicities (CVTs). Thus, RAAS inhibitors (RAASi) may be used as potential supplementary therapies in cancer treatment and CVT prevention. Oncological treatments have evolved significantly, impacting patient survival and safety profiles. However, they pose cardiovascular risks, necessitating strategies for mitigating adverse effects. The main drug classes used in oncology include anthracyclines, anti-HER2 therapies, immune checkpoint inhibitors (ICIs), and vascular endothelial growth factor (VEGF) signaling pathway inhibitors (VSPI). While effective against cancer, these drugs induce varying CVTs. RAASi adjunctive therapy shows promise in enhancing clinical outcomes and protecting the cardiovascular system. Understanding RAAS involvement in cancer and CVT can inform personalized treatment approaches and improve patient care.

A Multicenter, Open-Label Study to Evaluate the Long-term Safety and Efficacy of Adjunctive Brexpiprazole 2 mg Daily in Japanese Patients with Major Depressive Disorder.

Inadequate response to antidepressant monotherapy is common among patients with major depressive disorder (MDD). The efficacy and safety of adjunctive brexpiprazole 2 mg/day has recently been confirmed during the 6-week, randomized, placebo-controlled phase 2/3 (BLESS) study, which evaluated brexpiprazole at 1 mg/day and 2 mg/day versus placebo as adjunctive therapy to antidepressant therapies in 740 Japanese patients with MDD and an inadequate response to antidepressant monotherapy. This study evaluated the long-term safety and efficacy of adjunctive fixed-dose brexpiprazole 2 mg/day in Japanese patients with MDD. An open-label, 52-week study enrolled rollover patients who completed the 6-week, double-blind, randomized, placebo-controlled phase 2/3 BLESS study (NCT03697603), and de novo patients aged ≥ 65 years. Patients were titrated to fixed-dose brexpiprazole 2 mg/day from Week 1. Safety assessments included treatment-emergent adverse events (TEAEs; primary outcome) and clinical and laboratory variables. Efficacy was assessed using the Montgomery-Åsberg Depression Rating Scale(MADRS), Clinical Global Impression-Improvement (CGI-I) scale, Hamilton Depression Rating Scale (HAM-D) 17-item total score, and Sheehan Disability Scale (SDS) score. In total, 247 patients [rollover, n = 216; de novo (previously unexposed), n = 31] were included in the safety/efficacy populations, and 138 (rollover, n = 132; de novo, n = 6; 55.9%) completed the study. Common TEAEs (incidence ≥ 10%) were weight gain [33.2% (n = 82)], akathisia [23.5% (n = 58)], nasopharyngitis [21.1% (n = 52)], and somnolence [10.5% (n = 26)]. TEAEs leading to treatment discontinuation occurred in 26.7% of patients receiving brexpiprazole and 58.1% of de novo patients. The mean (SD) increase in body weight from baseline to Week 52 [observed cases (OC)] was 4.2 (6.5) kg (n = 138); 44.5% (n = 110) had weight gain ≥ 7% at any postbaseline visit. There were no cases of tardive dyskinesia and no AEs related to suicide/suicide attempts. One death occurred (unknown cause), which was unrelated to study treatment. Improvements in the MADRS total score were observed from baseline over the course of the 52-week study [mean (SD) change at Week 52 (OC): - 7.3 (8.7)] for all patients receiving brexpiprazole. The overall MADRS response rate and remission rate in patients receiving brexpiprazole was 41.3% (n = 57) and 34.8% (n = 48), respectively, at Week 52 (OC). Improvements in CGI-S, HAM-D 17 item total score, and SDS mean scores were also observed from baseline over the 52-week study, with a mean (SD) change from baseline at Week 52 (OC) of - 0.8 (1.0), - 5.9 (6.3), and - 1.0 (2.2), respectively, indicating a sustained improvement in symptoms with long-term brexpiprazole treatment. This is the first study to evaluate the safety profile of brexpiprazole 2 mg/day in Japanese patients with MDD, including older adults, which is similar to previous reports, with no new safety risks, and continued efficacy over 52 weeks.

A multicenter, randomized, double-blind, placebo-controlled trial to evaluate the effect of Tongmai Yangxin pill on ventricular remodeling in acute anterior STEMI patients after primary PCI

BackgroundAcute ST-segment elevation myocardial infarction (STEMI) is a severe form of coronary heart disease and a leading cause of mortality and morbidity. This can mainly be ascribed to adverse ventricular remodeling (VR). However, the efficacy of existing treatment strategies for STEMI is not entirely satisfactory. Tongmai Yangxin Pill (TMYX), a patented traditional Chinese medicine (TCM), has been approved for treating various cardiovascular diseases. PurposeThe purpose was to assess the effect of TMYX on VR in acute STEMI patients undergoing primary percutaneous coronary intervention (PPCI). Study DesignA multicenter, randomized, double-blinded, and placebo-controlled trial conducted across 11 hospitals in China. MethodA total of 270 patients with acute anterior STEMI, undergoing PPCI within 10 days of symptom onset were enrolled and randomly assigned to receive either a placebo or TMYX, in addition to guideline-directed treatments for STEMI. The primary endpoint was a change in left ventricular end-diastolic volume index (LVEDVI) at 12 weeks. ResultAmong the 270 randomized patients, 218 (TMYX: 109 and placebo: 109) were included in the per-protocol analysis. At 4 and 12 weeks, TXMY significantly improved LVEDVI than the placebo group ([-2.17(-9.24, 8.28) vs. 3.76(-2.38, 11.48), p < 0.05] and [-1.17 (-12.19, 12.88) vs. 4.46 (-2.89, 11.99), p < 0.05]). Changes in left ventricular end-diastolic volume (LVEDV) at 4 weeks were superior in the TMYX group than the placebo group (-4.37 (-17, 13.99) vs. 7.41 (-4.56, 21.79), p < 0.05). Cardiac magnetic resonance imaging (CMRI) showed that left ventricular ejection fraction (LVEF) was significantly greater in the TMYX group than in the placebo group at 4 weeks. There were no statistically significant differences between groups for left ventricular end-systolic volume (LVESV), left ventricular end-systolic volume index (LVESVI), 6 min walking distance (6MWD), and major adverse cardiac and cerebrovascular events (MACCEs) (p > 0.05). ConclusionTMYX, as an adjunctive therapy in addition to STEMI guideline-directed treatments, significantly delayed VR in patients with acute anterior STEMI undergoing PPCI within 10 days of symptom onset.

The causes of pulmonary hypertension and the benefits of aerobic exercise for pulmonary hypertension from an integrated perspective.

Pulmonary hypertension is a progressive disease of the pulmonary arteries that begins with increased pulmonary artery pressure, driven by progressive remodeling of the small pulmonary arteries, and ultimately leads to right heart failure and death. Vascular remodeling is the main pathological feature of pulmonary hypertension, but treatments for pulmonary hypertension are lacking. Determining the process of vascular proliferation and dysfunction may be a way to decipher the pathogenesis of pulmonary hypertension. In this review, we summarize the important pathways of pulmonary hypertension pathogenesis. We show how these processes are integrated and emphasize the benign role of aerobic exercise, which, as an adjunctive therapy, may be able to modify vascular remodeling in pulmonary hypertension.

A double-blind, placebo-controlled, randomised withdrawal study of adjunctive brexpiprazole maintenance treatment for major depressive disorder.

To compare time to relapse in patients with major depressive disorder (MDD) stabilised on antidepressant treatment (ADT) + brexpiprazole who were randomised to continued adjunctive brexpiprazole or brexpiprazole withdrawal (switch to placebo). This Phase 3, multicentre, double-blind, placebo-controlled, parallel-arm, randomised withdrawal study enrolled adults with MDD and inadequate response to 2–3 ADTs. All patients started on adjunctive brexpiprazole 2–3 mg/day (Phase A, 6–8 weeks). Patients whose symptoms stabilised (Phase B, 12 weeks) were randomised 1:1 to adjunctive brexpiprazole or adjunctive placebo (Phase C, 26 weeks). The primary endpoint was time to relapse in Phase C. Depression rating scale score changes were secondary endpoints. 1149 patients were enrolled and 489 patients were randomised (ADT + brexpiprazole n = 240; ADT + placebo n = 249). Median time to relapse was 63 days from randomisation in both treatment groups for patients who received ≥1 dose. Relapse criteria were met by 22.5% of patients (54/240) on ADT + brexpiprazole and 20.6% (51/248) on ADT + placebo (hazard ratio, 1.14; 95% confidence interval, 0.78–1.67; p = 0.51, log-rank test). Depression scale scores improved during Phases A–B and were maintained in Phase C. Mean weight increased by 2.2 kg in Phases A–B and stabilised in Phase C. Time to relapse was similar between continued adjunctive brexpiprazole and brexpiprazole withdrawal; in both groups, ∼80% of stabilised patients remained relapse free at their last visit. Adjunctive brexpiprazole therapy was generally well tolerated over up to 46 weeks, with minimal adverse effects following brexpiprazole withdrawal.ClinicalTrials.gov identifier: NCT03538691.

Comparative Preclinical Pharmacokinetics and Disposition of Favipiravir Following Pulmonary and Oral Administration as Potential Adjunct Therapy Against Airborne RNA Viruses.

Favipiravir is administered orally, even against airborne RNA viruses, in a loading-dose/maintenance dose regimen. We investigated whether-(a) pulmonary delivery of favipiravir would generate high concentrations in the luminal side of the respiratory tract; and (b) avoiding first-pass metabolism by the liver by inhaled drug would generate comparable pharmacokinetics (PK) with doses significantly smaller than the oral maintenance dose. A dry powder inhalation (DPI) of favipiravir formulated by mixing with Inhalac 400® was prepared and characterized. Inhalations of ~ 120µg dose strength, with or without a prior oral loading dose were administered to mice. Comparator mice received human-equivalent oral doses (3mg). Three mice per sampling time point were sacrificed and favipiravir concentrations in the blood plasma, bronchio-alveolar lavage fluid (BALF) and lung tissue homogenate determined by HPLC. One-compartment PK modeling of concentration-time data indicated that the area under the curve (AUC0-24h) generated in the BALF recovered from mice receiving inhalations of ~ 1/25th of the oral dose subsequent to an oral loading dose was 86.72 ± 4.48µg⋅mL-1⋅h. This was consistently higher than the AUC observed in the BALF of orally-dosed mice (56.71 ± 53.89µgmL-1⋅h). In blood serum, the respective values of AUC were 321.55 ± 124.91 and 354.71 ± 99.60µg⋅mL-1⋅h. Pulmonary delivery of significantly smaller doses of favipiravir generates meaningful drug disposition and pharmacokinetics at the site of respiratory viral infections. We provide the rationale for designing a self-administered, non-invasive, low-cost, targeted drug delivery system against airborne RNA virus infection.
