Understanding Effect of Ayurvedic Treatment in Prameha (Diabetes Mellitus) and its Upadrava (Complications)

Prameha is a syndrome described in the ancient Ayurvedic texts that includes clinical conditions involving metabolic syndrome and is said to be a Santarapanajanya Vyadhi. Prameha literary means anomalies of urinary secretions. On the basis of clinical features of Prameha, it correlates with diabetes mellitus. Diabetes mellitus is a metabolic cum vascular syndrome of multiple etiologies characterised by chronic hyperglycemia. The disease Prameha can be understood as having three stages based on the severity of Dhatudusti. With the Dushti of all Dhatus, Upadrava of Prameha are manifested. Case: Present case study deals with a female patient 49 years old suffering from increased frequency of micturition during night and Parshvashool with coughing from 3 years. On taking a detailed history it was found that, it was Upadrava of Prameha. Treatment protocol: Patient was given Pradhamana Nasyam with Pippali Churna after proper intervention of Snehana and Nadi Swedan on chest, supraclvicular region, and Kati Pradesh on empty stomach in the early morning. After that a freshly prepared Kwatha about 50ml of Kalmegh Churna, Punarnavamool, Giloy and Shunthi was given at BD dose. And the same drugs were used for Lepan on Kati Pradesh. Results: Parshvashool and coughing was completely cured, BSF and PPBS came to its normal range, creatinine level decreased and there was a significant reduction in fatty liver. Conclusion: With proper therapy, drug intervention, diet control and exercise Prameha and its Upadrava can be managed successfully.

Neurological phenotypes and treatment outcomes in Eagle syndrome: systematic review and meta-analysis.

Eagle syndrome is caused by an elongated styloid process affecting carotid arteries and cranial nerves. Pain, dysphagia, tinnitus, paresthesia (classic subtype), and neurovascular events (vascular subtype) may be triggered by head movements or arise spontaneously. However, Eagle syndrome remains underappreciated in the neurological community. We aimed to determine the most common neurological and non-neurological clinical presentations in patients with Eagle syndrome and to assess the clinical outcome post-surgical resection in comparison to non-surgical therapies. We conducted a systematic review of patient-level data on adults with Eagle syndrome, following PRISMA guidelines. We extracted data on demographics, presenting symptoms, neurological deficits, radiological findings, and treatments, including outcomes and complications, from studies in multiple indexing databases published between 2000 and 2023. The study protocol is registered with PROSPERO. In total, 285 studies met inclusion criteria, including 497 patients with Eagle syndrome (mean age 47.3 years; 49.8% female). Classical Eagle (370 patients, 74.5%) was more frequent than vascular Eagle syndrome (117 patients, 23.5%, p < 0.0001). Six patients (1.2%) presented with both variants and the subvariant for four patients (0.8%) was unknown. There was a male preponderance (70.1% male) in the vascular subtype. A history of tonsillectomy was more frequent in classic (48/153 cases) than in vascular (2/33 cases) Eagle syndrome (Odds Ratio 5.2, 95% CI [1.2-22.4]; p = 0.028). By contrast, cervical movements as trigger factors were more prevalent in vascular (12/33 cases) than in classic (7/153 cases) Eagle syndrome (Odds Ratio 7.95, 95% CI [2.9-21.7]; p = 0.0001). Headache and Horner syndrome were more frequent in vascular Eagle syndrome and dysphagia and neck pain more prominent in classic Eagle syndrome (all p < 0.01). Surgically treated patients achieved overall better outcomes than medically treated ones: Eighty-one (65.9%) of 123 medically treated patients experienced improvement or complete resolution, while the same applied to 313 (97.8%) of 320 surgical patients (Odds Ratio 1.49, 95% CI [1.1-2.0]; p = 0.016). Eagle syndrome is underdiagnosed with potentially serious neurovascular complications, including ischemic stroke. Surgical treatment achieves better outcomes than conservative management. Although traditionally the domain of otorhinolaryngologist, neurologist should include this syndrome in differential diagnostic considerations because of the varied neurological presentations that are amenable to effective treatment.

Dengue NS1 antibodies are associated with clearance of viral NS1.

Dengue vascular permeability syndrome is the primary cause of death in severe dengue infections. The protective versus potentially pathogenic role of dengue NS1 antibodies are not well understood. The main goal of this analysis was to characterize the relationship between free NS1 concentration and NS1 antibody titers in primary and secondary dengue infection in order to better understand the presence and duration of NS1 antibody complexes in clinical dengue infections. Hospitalized participants with acute dengue infection were recruited from Northern Colombia between 2018 to 2020. Symptom assessment including dengue signs and symptoms, chart review and blood collection was performed. Primary versus secondary Dengue was assessed serologically. NS1 titers and anti-NS1 antibodies were measured daily. Patients with secondary infection have higher antibody titers than those in primary infection, and we find a negative correlation between anti-NS1 antibody titer and NS1 protein. We demonstrate that in a subset of secondary infection, there are indeed NS1 antibody-antigen complexes at the admission day during the febrile phase that are not detectable by the recovery phase. Furthermore, dengue infection status is associated with higher circulating sialidases. The negative correlation between antibody and protein suggests that antibodies may play a role in clearing this viral protein.

MB2033, an anti-PD-L1 × IL-2 variant fusion protein, demonstrates robust anti-tumor efficacy with minimal peripheral toxicity

Interleukin-2 (IL-2), a cytokine with pleiotropic immune effects, was the first approved cancer immunotherapy agent. However, IL-2 is associated with systemic toxicity due to binding with its ligand IL-2Rα, such as vascular leakage syndrome, limiting its clinical applications. Despite efforts to extend the half-life of IL-2 and abolish IL-2Rα interactions, the risk of toxicity remains unresolved. In this study, we developed the bispecific fusion protein MB2033, comprising a novel IL-2 variant (IL-2v) connected to anti-programmed death ligand 1 (PD-L1) via a silenced Fc domain. The IL-2v of MB2033 exhibits attenuated affinity for IL-2Rβγ without binding to IL-2Rα. The binding affinity of MB2033 for PD-L1 is greater than that for IL-2Rβγ, indicating its preferential targeting of PD-L1+ tumor cells to induce tumor-specific immune activation. Accordingly, MB2033 exhibited significantly reduced regulatory T cell activation, while inducing comparable CD8+ T cell activation to recombinant human IL-2 (rhIL-2). MB2033 induced lower immune cell expansion and reduced cytokine levels compared with rhIL-2 in human peripheral blood mononuclear cells, indicating a decreased risk of peripheral toxicity. MB2033 exhibited superior anti-tumor efficacy, including tumor growth inhibition and complete responses, compared with avelumab monotherapy in an MC38 syngeneic mouse model. In normal mice, MB2033 was safer than non-α IL-2v and tolerable up to 30 mg/kg. These preclinical results provide evidence of the dual advantages of MB2033 with an enhanced safety and potent clinical efficacy for cancer treatment.

Venous Compressive Disorders

Venous compressive disorders are a heterogenous group of vascular syndromes characterized by extrinsic venous compression that can lead to complications of venous hypertension or venous thrombosis. Endovascular damage secondary to deep venous thrombosis (DVT) can result in post-thrombotic syndrome (PTS), a potentially debilitating condition that can be associated with significant morbidity in the pediatric population. Here we discuss 4 venous compressive disorders: iliac vein compression (May-Thurner syndrome [MTS]); subclavian vein compression at the venous thoracic inlet (Paget-Schroetter syndrome); left renal vein compression (nutcracker syndrome); and popliteal vein compression (popliteal entrapment syndrome) with a focus on clinical evaluation and diagnostic methods. Where endovascular therapy is appropriate, specific procedural considerations including procedure indications, equipment, procedural steps, technical challenges, complications, clinical follow-up and expected outcomes are discussed.

Role Of Acute Vascular Distress Syndrome In The Development Of Multisystem Inflammatory Syndrome In Sars-Cov-2 And Modern Views On The Research And Treatment Of Critical Coronavirus

Background: The COVID-19 pandemic, caused by SARS-CoV-2, has highlighted the complex pathology of the virus, which extends beyond respiratory symptoms to include multisystem inflammatory syndrome (MIS). This review explores the role of Acute Vascular Distress Syndrome (AVDS) in the development of MIS in both adults (MIS-A) and children (MIS-C), providing a comprehensive overview of modern research and treatment approaches for severe coronavirus infections. Methods and Materials: This review synthesizes findings from multiple studies and clinical reports to analyze the mechanisms by which SARS-CoV-2 induces AVDS and subsequently MIS. Key materials include molecular and cellular research data, clinical case studies, and treatment protocols. Diagnostic tools such as PCR and serological testing, as well as various biomarkers like neurofilament light chain and galectin-3, are discussed to elucidate their roles in identifying and managing severe COVID-19 cases. Results: The interaction between SARS-CoV-2 and host endothelial cells, mediated by ACE2 receptors, triggers a cascade of inflammatory responses leading to AVDS. This syndrome is characterized by severe endothelial dysfunction, cytokine storms, and mitochondrial distress, which collectively contribute to the pathogenesis of MIS. Clinical evidence indicates that AVDS is a critical factor in the severity of COVID-19, with widespread implications for multiple organ systems, including the central and peripheral nervous systems. Conclusion: Understanding the role of AVDS in MIS development offers valuable insights into the pathophysiology of severe COVID-19. Effective management requires a multifaceted approach, combining antiviral therapies, immunomodulators, and supportive treatments like extracorporeal membrane oxygenation (ECMO). Future research should focus on targeted therapies to mitigate endothelial damage and improve patient outcomes in critical COVID-19 cases.

Vascular syndrome predicts the development and course of epilepsy after perinatal stroke.

Epilepsy develops in one third of the patients after perinatal stroke. It is still unclear which vascular syndrome of ischemic stroke carries higher risk of epilepsy. The aim of the current study was to evaluate the risk of epilepsy according to the vascular syndrome of perinatal stroke. The study included 39 children with perinatal arterial ischemic stroke (13 with anterior or posterior trunk of the distal middle cerebral artery occlusion, 23 with proximal or distal M1 middle cerebral artery occlusion and three with lenticulostriate arteria infarction), and 44 children with presumed perinatal venous infarction. Magnetic resonance imaging obtained at the chronic stage was used to evaluate the vascular syndrome of stroke. The median follow-up time was 15.1 years (95% CI: 12.4-16.5 years), epilepsy developed in 19/83 (22.9%) patients. The cumulative probability to be without epilepsy at 15 years was 75.4% (95% CI: 65.8-86.4). The probability of having epilepsy was higher in the group of proximal or distal M1 artery occlusion compared to patients with periventricular venous infarction (HR 7.2, 95% CI: 2.5-26, p = .0007). Patients with periventricular venous infarction had significantly more often status epilepticus or spike-wave activation in sleep ≥85% of it compared to patients with anterior or posterior trunk of the distal middle cerebral artery occlusion (OR = 81; 95% CI: 1.3-5046, p = .029). The emphasis of this study is placed on classifying the vascular syndrome of perinatal stroke and on the targeted follow-up of patients for epilepsy until young adulthood. The risk for having epilepsy after perinatal stroke is the highest in children with proximal or distal M1 middle cerebral artery occlusion. Patients with periventricular venous infarction have a more severe course of epilepsy.

Shots fired: evaluation of vascular injury, compartment syndrome, and transfusion rates among civilian ballistic orthopaedic fracture patients presenting to two Level I trauma centres.

This study investigates baseline patient demographics and predictors of vascular injury, blood transfusion, and compartment syndrome in patients with orthopaedic fractures secondary to GSWs at two high-volume Level I trauma centres. A retrospective chart review of all GSW-related trauma patients at two Level I trauma centres between July 2019 and September 2021 was conducted. Chi-squared and two-tailed independent t tests were used for data analysis, and logistic regression with odds ratios (OR) determined predictors of primary outcomes. Among 478 GSW patients, 94 (19.7%) sustained 130 orthopaedic fractures, most commonly at the lower extremity (77.7%). Orthopaedic fracture patients showed significantly higher rates of vascular injury (29.8 vs. 4.7%, p < 0.001), transfusion (27.7 vs. 12.8%, p = 0.006), and compartment syndrome (3.2 vs. 0.3%, p = 0.011) compared to non-orthopaedic injury patients. Univariable analysis identified ankle (OR = 47.50, p < 0.001) and hip/femur fractures (OR = 5.31, p < 0.001) as predictors of vascular injury. Multivariable logistic regression revealed lower extremity vascular injury (OR = 54.69, p = 0.006) and anatomic fracture sites of the humerus (OR = 15.17, p = 0.008), clavicle/scapula (OR = 11.30, p = 0.009), and acetabulum/pelvis (OR = 7.17, p = 0.025) as predictors of blood transfusion. Univariable analysis showed lower extremity vascular injury (OR = 30.14, p = 0.007) as a predictor of compartment syndrome. These findings underscore the importance of diagnosing and managing vascular injuries and compartment syndrome in GSW-related orthopaedic fractures, emphasizing the necessity for targeted transfusion strategies in such cases.

Vascular compression syndromes in the abdomen and pelvis: a concise pictorial review.

Vascular compression syndromes are a diverse group of pathologies that can manifest asymptomatically and incidentally in otherwise healthy individuals or symptomatically with a spectrum of presentations. Due to their relative rarity, these syndromes are often poorly understood and overlooked. Early identification of these syndromes can have a significant impact on subsequent clinical management. This pictorial review provides a concise summary of seven vascular compression syndromes within the abdomen and pelvis including median arcuate ligament (MAL) syndrome, superior mesenteric artery (SMA) syndrome, nutcracker syndrome (NCS), May-Thurner syndrome (MTS), ureteropelvic junction obstruction (UPJO), vascular compression of the ureter, and portal biliopathy. The demographics, pathophysiology, predisposing factors, and expected treatment for each compression syndrome are reviewed. Salient imaging features of each entity are illustrated through imaging examples using multiple modalities including ultrasound, fluoroscopy, CT, and MRI.

Dermato-Radiological Evaluation of Congenital Limb Overgrowth Vascular Syndromes

Abstract International Society for the Study of Vascular Anomalies classification defines Congenital Limb Overgrowth Vascular Syndromes (CLOS) as a subset of vascular syndromes with other abnormalities that present with unilateral limb overgrowth. It includes Klippel–Trenaunay Syndrome, Parkes–Weber Syndrome, CLOVES (Congenital Lipomatous Overgrowth, Vascular Malformations, Epidermal Nevi, Spinal/Skeletal Anomalies/Scoliosis) Syndrome, Proteus Syndrome, PTEN Hamartomatous Syndrome, and Fibroadipose Vascular Anomaly. Due to their rare and complex nature, a multidisciplinary approach to diagnosis and treatment is required. A thorough clinical and radiological workup can go miles in reflecting on the patient’s outcome. Here we report five cases of CLOS with their detailed dermato-radiological profiles.

Doppler Ultrasound of the Renal Vasculature.

Ultrasound is the first-line imaging modality used in patients with suspected renovascular disease. Common indications include renovascular hypertension and unexplained renal dysfunction. We review the ultrasound imaging findings of various pathologies involving the renal vessels, including the renal arteries (atherosclerotic stenosis, fibromuscular dysplasia, dissection, arteriovenous fistula, and aneurysm) and veins (tumor and bland thrombus as well as vascular compression syndromes). The current role of renal artery stent placement for atherosclerotic stenosis is also discussed.

Abstract 2475: MB5029: A novel anti-PD-1 x IL-2v with improved safety profile and enhanced anti-tumor efficacy by selectively targeting activated T cells

Abstract Interleukin-2 (IL-2) offers therapeutic potential for cancer treatment, however, its clinical application is limited due to systemic adverse effects, such as vascular leakage syndrome (VLS). Notably, the high affinity of IL-2 for the IL-2 receptor α (IL-2Rα) activates immune-suppressive Treg cells and endothelial cells, leading to undesired outcomes. To address this challenge, a number of clinical studies are under development including non-α IL-2 variant (IL-2v) drugs and further the anti-PD-1 x IL-2v for targeted delivery of its IL-2v to PD-1 enriched T cells. Nevertheless, concerns about peripheral toxicity have not yet been solved. Thus, here we present MB5029, a novel anti-PD-1 x IL-2v bispecific fusion protein with modulated IL-2R binding affinity to mitigate the peripheral toxicity maintaining the anti-tumor efficacy. MB5029 has unique characteristics with no binding affinity to IL-2Rα and reduced binding affinity to IL-2Rγ, which is widely and highly expressed in various immune cells. MB5029 exhibited strong STAT5 phosphorylation activity under activated conditions but weak activity in the resting conditions, while the anti-PD-1 x IL-2v (non-α) showed strong STAT5 phosphorylation in both resting and activated conditions. In addition, MB5029 strongly induced the expansion of CD8+ T cells in the activated conditions but less expansion of CD8+ T cells in the resting conditions, in contrast to anti-PD-1 x IL-2v (non-α). The murine surrogate of MB5029 showed remarkable anti-tumor efficacy without body weight loss at the dose range of 1 to 10 mg/kg, whereas anti-muPD-1 x IL-2v (non-α) showed significant body weight loss in several tumor-bearing mice models. Moreover, MB5029 showed 100% complete regression (6/6) at the dose of 5 mg/kg or higher in the MC38 tumor model. The mice with complete response showed no signs of relapse upon tumor re-challenge until day 56, indicating a durable memory response. MB5029 exhibited a comparatively superior safety profile in normal mice. While anti-muPD-1 x IL-2v (non-α) led to significant body weight loss at the dose of 5 mg/kg in normal mice, the murine surrogate of MB5029 was shown to be well-tolerated up to a dose of 30 mg/kg without body weight loss. MB5029 exhibited dose-proportional PK properties and induced expansion of CD8+ T cells in a dose-dependent manner in cynomolgus monkeys. MB5029 is shown to be well-tolerated up to 9 mg/kg without severe clinical signs and no significant increase in eosinophil and cytokines in the blood. Overall, MB5029 represents a promising potential as an immunotherapeutic approach, as it has demonstrated both strong efficacy and good tolerability, along with improved safety margins.

Safety and efficacy of dynamic catheter-directed cerebral digital subtraction angiography for diagnosis of bowhunter syndrome spectrum disorders: A systematic review of the literature.

Dynamic catheter-directed cerebral digital subtraction angiography (dcDSA) is the gold standard for diagnosing dynamic vascular occlusion syndromes such as bowhunter syndrome (BHS). Nonetheless, concerns about its safety exist and no standardized protocols have been published to date. We describe our methodology and insights regarding the use of dcDSA in patients with BHS. We also perform a systematic literature review to identify cases of typical and atypical presentations of BHS wherein dcDSA was utilized and report on any procedural complications related to dcDSA. Our study included 104 cases wherein dcDSA was used for the diagnosis of BHS. There were 0 reported complications of dcDSA. DcDSA successfully established diagnosis in 102 of these cases. Thirty-eight cases were deemed atypical presentations of BHS. Fourteen patients endorsed symptoms during neck flexion/extension. In eight cases, there was dynamic occlusion of bilateral vertebral arteries during a single maneuver. Three patients had multiple areas of occlusion along a single vertebral artery (VA). An anomalous entry of the VA above the C6 transverse foramen was observed in four patients. One patient had VA occlusion with neutral head position and recanalization upon contralateral lateral head tilt. Our study highlights the safety and diagnostic benefits of dcDSA in characterizing the broad spectrum of BHS pathology encountered in clinical practice. This technique offers a powerful means to evaluate changes in cerebral blood flow and cervical arterial morphology in real time, overcoming the constraints of static imaging methods. Our findings pave the way for further studies on dcDSA to enhance cross-sectional imaging methods for the characterization of BHS and other dynamic vascular occlusion syndromes.

A Review on The Pathogenesis of Cardiovascular Disease of Flaviviridea Viruses Infection.

Members of the Flaviviridae family, encompassing the Flavivirus and Hepacivirus genera, are implicated in a spectrum of severe human pathologies. These diseases span a diverse spectrum, including hepatitis, vascular shock syndrome, encephalitis, acute flaccid paralysis, and adverse fetal outcomes, such as congenital heart defects and increased mortality rates. Notably, infections by Flaviviridae viruses have been associated with substantial cardiovascular compromise, yet the exploration into the attendant cardiovascular sequelae and underlying mechanisms remains relatively underexplored. This review aims to explore the epidemiology of Flaviviridae virus infections and synthesize their cardiovascular morbidities. Leveraging current research trajectories and our investigative contributions, we aspire to construct a cogent theoretical framework elucidating the pathogenesis of Flaviviridae-induced cardiovascular injury and illuminate prospective therapeutic avenues.

Prevalence of Early Vascular Aging Syndrome in Men Working Under Noise Exposure

Noise can be one of the factors provoking the premature development of changes in the artery wall associated with age. Aim: to assess the stiffness of the vascular wall and the prevalence of early vascular aging syndrome in men of working age, depending on contact with noise, smoking status and the presence of hypertension. Materials and methods. 148 men worked in noise and 90 men for whom the level of all harmful production factors in the workplace did not exceed the permissible standards were examined. The average age of the examined patients was 41.6 ± 9.9 years, 133 people (55.9 %) were smokers, 43 people (18.1 %) were obese, 47 people (19.7 %) had a complicated heredity, 132 people (55.5 %) had hypercholesterolemia, and 37 people (15.5 %) suffered from arterial hypertension (AH). Each of the patients suffering from hypertension received antihypertensive therapy. There were no significant differences in the structure of antihypertensive therapy in the compared groups of patients. The groups of surveyed were comparable in age, body mass index, prevalence of smoking, obesity and hypertension. All patients underwent volumetric sphygmography according to the standard procedure in the morning on the VaSera 1500N device (FukudaDenshi, Japan), the device automatically determined the cardio-ankle vascular index on the right and left (R/L — CAVI), the estimated age of the arteries. The syndrome of early vascular aging (EVA syndrome) was considered to be a clinical condition associated with an excess of the estimated age of the arteries of the patient’s passport age by 4 years or more (VaSera criteria). Results and discussion. After exclusion of smokers and hypertensive patients from the analysis and correction for age, the vascular wall stiffness index on the right and left in the main group of patients significantly exceeded the indicated indicator in the comparison group. R — CAVI was 7.2 [6.9; 7.9] and 7.05 [6.05; 7.45], respectively, p=0.02; L — CAVI was 7.3 [7.0; 7.9] and 6.85 [6.05; 7.65], respectively, p =0.007. In the group of people working in noise, the estimated age of the arteries significantly exceeded the passport age (p=0.004), whereas in the control group these indicators were comparable (p=0.27). The prevalence of EVA syndrome in the main group of patients was 14 cases (27.5 %), which was 8.6 times higher than the prevalence of EVA syndrome in the comparison group — 1 case (3.2 %); p=0.004. The comparability of the patient groups according to the main cardiovascular risk factors and the exclusion criteria from the study suggested that the identified changes in the state of the vascular wall are associated with the effects of noise on the body of the examined. Conclusion. Noise can be a factor that accelerates vascular aging. It is necessary to monitor the state of the cardiovascular system in persons working in noise.

“Inherited cardiovascular disease mindset” can identify concealed inherited conditions at cardio-oncology evaluation: An opportunistic screening.

IntroductionBaseline cardiovascular (CV) risk stratification is recommended in all cancer patients. Integrating all clinical information (personal/family history, ECG and echocardiogram) can properly identify high-risk patients. We aimed to evaluate the concealed inherited CV conditions detected in mandatory CV screening performed at a Cardio-Oncology Unit. Methodsretrospective study of all consecutive cancer patients referred to the Cardio-Oncology Unit for CV evaluation (2020−2023). Inherited CV conditions diagnosis and genetic testing was performed according to guidelines. Results1984 cancer patients underwent CV screening. Sanger sequencing was indicated in 1 patient, excluding the genetic family disease. NGS sequencing was performed in 11 cancer patients with normal left ventricular ejection fraction (LVEF): 2 due to aortic syndrome evaluation (identifying 1 vascular Ehrler-Danlos syndrome due to COL3A1 p.Arg242Ter), 4 channelopathies (2 Long QT syndrome and 2 Brugada's), 4 hypertrophic cardiomyopathies and 1 non-dilated left ventricular cardiomyopathy (NDLVC). Among the 12 patients with reduced LVEF, one was diagnosed with NDLVC, and chemotherapy-induced dilated cardiomyopathy was only ascribable in 3 of them. ConclusionIntegrating clinical information at mandatory baseline CV toxicity risk cardio-oncology evaluation, can identify high-risk cancer patients with concealed inherited conditions. Keeping an “inherited cardiovascular disease-oriented mindset” to implement opportunist screenings is encouraged.
