[Vascular occlusion following profile harmonization of the chin with hyaluronic acid fillers]. / Vasculaire occlusie na profielharmonisatie van de kin met hyaluronzuur fillers.

The use of dermal fillers for cosmetic procedures has increased rapidly both worldwide and in the Netherlands in recent years, which has led to an absolute increase in reported side effects and complications. Although most of these complications are mild, serious complications such as vascular occlusion can also occur. In this article, we describe a case of a 35-year-old woman who showed signs of reduced tissue perfusion and the early stage of skin necrosis following injection of hyaluronic acid fillers in the chin. This complication was successfully treated by ultrasound-guided injection of hyaluronidase, resulting in a full recovery without residual symptoms. To minimize the risk of serious complications treatment with hyaluronic acid fillers should be carried out by an experienced practitioner.

Cardiovascular risk of gabapentin and pregabalin in patients with diabetic neuropathy.

BACKGROUND: Gabapentin and pregabalin are commonly prescribed medications to treat pain in patients with diabetic neuropathy. Gabapentin and pregabalin can cause fluid retention, which is hypothesized to be associated with cardiovascular diseases. However, whether long-term use of gabapentin and pregabalin is associated with adverse cardiovascular diseases remains unknown. This study aims to examine the association between gabapentin use, pregabalin use and several adverse cardiovascular events. METHODS: This retrospective cohort study used propensity score matching within patient electronic health records (EHRs) from a multicenter database with 106 million patients from 69 health care organizations in the US. The study population comprised 210,064 patients who had a diagnosis of diabetic neuropathy and were prescribed diabetic neuropathy medications in their EHRs. The exposure cohort comprised patients who were prescribed gabapentin or pregabalin to treat diabetic neuropathy. The comparison cohort comprised patients who were not prescribed either gabapentin or pregabalin but were prescribed other drugs to treat diabetic neuropathy. The outcomes of interest were myocardial infarcts, strokes, heart failure, peripheral vascular disease, and venous thromboembolic events. We calculated hazard ratios (HRs) and 95% confidence intervals (CIs) for 3-month and 5-year risk for adverse cardiovascular events between the propensity score-matched cohorts. RESULTS: Both gabapentin and pregabalin were associated with increased risk of 5-year adverse cardiovascular events compared with the comparison group. In patients prescribed gabapentin, the highest risk was observed for deep venous thrombosis (HR: 1.58, 95% CI 1.37-1.82), followed by pulmonary embolism (HR: 1.5, 95% CI 1.27-1.76), peripheral vascular disease (HR: 1.37, 95% CI 1.27-1.47), stroke (HR: 1.31, 95% CI 1.2-1.43), myocardial infarction (HR: 1.25, 95% CI 1.14-1.38) and heart failure (HR: 1.14, 95% CI 1.07-1.21). In patients prescribed pregabalin, the highest risk was observed for deep venous thrombosis (HR: 1.57, 95% CI 1.31-1.88), followed by peripheral vascular disease (HR: 1.35, 95% CI 1.22-1.49), myocardial infarction (HR: 1.29, 95% CI 1.13-1.47), pulmonary embolism (HR: 1.28, 95% CI 1.04-1.59), stroke (HR: 1.26, 95% CI 1.12-1.42), and heart failure (HR: 1.2, 95% CI 1.11-1.3). There were significant associations between short-term (3 month) gabapentin use and heart failure, myocardial infarction, peripheral vascular disease, deep venous thrombosis, and pulmonary embolism. Short-term (3 month) pregabalin use was associated with deep venous thrombosis, peripheral vascular disease. CONCLUSION: In patients with diabetic neuropathy who were prescribed gabapentin and pregabalin, there is an increased risk for heart failure, myocardial infarction, peripheral vascular disease, stroke, deep venous thrombosis, and pulmonary embolism with long-term use. Our findings suggest that increased risk for adverse cardiovascular events, along with other side effects, the efficacy of pain control and the degree of tolerance of the patient, should be considered when prescribing gabapentin and pregabalin long-term in patients with diabetic neuropathy.

Carnosine as a potential therapeutic for the management of peripheral vascular disease.

AIMS: To evaluate the potential role of carnosine in the management of peripheral vascular disease. DATA SYNTHESIS: Peripheral vascular disease is growing in its burden and impact; however it is currently under researched, and there are a lack of strong, non-invasive therapeutic options for the clinicians. Carnosine is a dipeptide stored particularly in muscle and brain tissue, which exhibits a wide range of physiological activities, which may be beneficial as an adjunct treatment for peripheral vascular disease. Carnosine's strong anti-inflammatory, antioxidant and antiglycating actions may aid in the prevention of plaque formation, through protective actions on the vascular endothelium, and the inhibition of foam cells. Carnosine may also improve angiogenesis, exercise performance and vasodilatory response, while protecting from ischemic tissue injury. CONCLUSIONS: Carnosine may have a role as an adjunct treatment for peripheral vascular disease alongside typical exercise and surgical interventions, and may be used in high risk individuals to aid in the prevention of atherogenesis. CLINICAL RECOMMENDATION: This review identifies a beneficial role for carnosine supplementation in the management of patients with peripheral vascular disease, in conjunction with exercise and revascularization. Carnosine as a supplement is safe, and associated with a host of beneficial effects in peripheral vascular disease and its key risk factors.

The Intervention of Nano-targeted Drugs & Angioplastryin Treatment and Prevention of Vascular Restenosis and its Influence on Monocyte Chemotactic Protein-1 in Lower Extremity Angiopathy.

It was to make use of the nano-targeted drugs and angioplastry to treat and prevent the vascular restenosis and analyze its influence on monocyte chemotactic protein 1 (MCP-1) of lower extremity angiopathy (LEA) patients since the patients with diabetic lower extremity angiopathy may be easily infected with vascular restenosis. In this article, the dexamethasone nano drugs were firstly prepared. After that, its related physical and chemical properties were tested, then, dexamethasone nano drugs were applied in treating patients with diabetic lower extremity angiopathy. The results showed that the prepared dexamethasone nanoparticles' encapsulation rate attained 99.2%. The laser light scattering experiment manifested that the particle size of the nanoparticles ranged from 200 to 300nm, and the average particle size was 258nm. The MCP-1 of the control group, conventional group, and observation group were 33.28±1.93 µg/mL, 78.27±9.73 µg/mL, and 75.29±8.99 µg/mL, respectively. The MCP-1 values of the conventional and observation groups were higher than that of the control group, and there was a notable difference (P<0.05). After interventional treatment, the MCP-1 level of the conventional group was 57.82±5.82 µg/mL, and that of the observation group was 41.93±6.92 µg/mL. The MCP-1 level of the group which received the treatment of nano-targeted drugs and angioplastry was superior to that of the conventional group which received the traditional operation, and there was a notable difference (P<0.05). In conclusion, MCP-1 is one of the major causes of lower extremity angiopathy. The nano-targeted drugs and angioplastry can raise the expression level of MCP-1 in patients with lower extremity angiopathy. The experimental results had a high application value and the nano-targeted drugs & angioplastry can be promoted clinically.

The correlation between platelet responsiveness to clopidogrel and CYP2C19 polymorphism in patients with peripheral vascular disease.

OBJECTIVE: Several patients undergoing endovascular intervention and bypass surgery present with high platelet reactivity following clopidogrel treatment. We aimed to determine the frequency of the genetic polymorphism of CYP2C19*2 and the contribution of this polymorphism along with other clinical parameters to clopidogrel response in an Egyptian population. PATIENTS AND METHODS: A total of 50 patients receiving clopidogrel at a maintenance dose of 75 mg daily post vascular intervention from January 1, 2019, to May 30, 2020, were enrolled in this study. Clopidogrel resistance was determined through platelet aggregation analysis using Chrono-Log® platelet aggregometer. Single-nucleotide polymorphism (SNP) genotyping was performed using quantitative real-time polymerase chain reaction (QRT-PCR). RESULTS: The incidence of clopidogrel resistance among this Egyptian population is about 22%. Univariate analysis demonstrated that CYP2C19*2 genotype (p = 0.001), high body mass index (BMI; p = 0.025), diabetes (p = 0.037),  high fasting blood glucose (FBG) level (p = 0.037), and high glycosylated hemoglobin (HbA1c) level (p = 0.004) were significantly associated with clopidogrel resistance. Multivariate analysis showed that CYP2C19*2 genotype (odds ratio (OR), 927.71; 95% confidence interval (CI), 1.915-449496.2; p = 0.030) and high BMI (OR, 1.789; 95% CI, 1.044-3.064; p = 0.034) were the most powerful predictors of clopidogrel resistance. CONCLUSIONS: Clopidogrel resistance in patients with peripheral vascular disease is associated with the presence of CYP2C19*2 allele, obesity, and diabetes; these factors should be considered prior to clopidogrel administration.

Cilostazol for intermittent claudication.

BACKGROUND: Peripheral arterial disease (PAD) affects between 4% and 12% of people aged 55 to 70 years, and 20% of people over 70 years. A common complaint is intermittent claudication (exercise-induced lower limb pain relieved by rest). These patients have a three- to six-fold increase in cardiovascular mortality.  Cilostazol is a drug licensed for the use of improving claudication distance and, if shown to reduce cardiovascular risk, could offer additional clinical benefits. This is an update of the review first published in 2007. OBJECTIVES: To determine the effect of cilostazol on initial and absolute claudication distances, mortality and vascular events in patients with stable intermittent claudication. SEARCH METHODS: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, and AMED databases, and the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registries, on 9 November 2020. SELECTION CRITERIA: We considered double-blind, randomised controlled trials (RCTs) of cilostazol versus placebo, or versus other drugs used to improve claudication distance in patients with stable intermittent claudication. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trials for selection and independently extracted data. Disagreements were resolved by discussion. We assessed the risk of bias with the Cochrane risk of bias tool. Certainty of the evidence was evaluated using GRADE. For dichotomous outcomes, we used odds ratios (ORs) with corresponding 95% confidence intervals (CIs) and for continuous outcomes we used mean differences (MDs) and 95% CIs. We pooled data using a fixed-effect model, or a random-effects model when heterogeneity was identified. Primary outcomes were initial claudication distance (ICD) and quality of life (QoL). Secondary outcomes were absolute claudication distance (ACD), revascularisation, amputation, adverse events and cardiovascular events. MAIN RESULTS: We included 16 double-blind, RCTs (3972 participants) comparing cilostazol with placebo, of which five studies also compared cilostazol with pentoxifylline. Treatment duration ranged from six to 26 weeks. All participants had intermittent claudication secondary to PAD. Cilostazol dose ranged from 100 mg to 300 mg; pentoxifylline dose ranged from 800 mg to 1200 mg. The certainty of the evidence was downgraded by one level for all studies because publication bias was strongly suspected. Other reasons for downgrading were imprecision, inconsistency and selective reporting. Cilostazol versus placebo Participants taking cilostazol had a higher ICD compared with those taking placebo (MD 26.49 metres; 95% CI 18.93 to 34.05; 1722 participants; six studies; low-certainty evidence). We reported QoL measures descriptively due to insufficient statistical detail within the studies to combine the results; there was a possible indication in improvement of QoL in the cilostazol treatment groups (low-certainty evidence). Participants taking cilostazol had a higher ACD compared with those taking placebo (39.57 metres; 95% CI 21.80 to 57.33; 2360 participants; eight studies; very-low certainty evidence). The most commonly reported adverse events were headache, diarrhoea, abnormal stools, dizziness, pain and palpitations. Participants taking cilostazol had an increased odds of experiencing headache compared to participants taking placebo (OR 2.83; 95% CI 2.26 to 3.55; 2584 participants; eight studies; moderate-certainty evidence).Very few studies reported on other outcomes so conclusions on revascularisation, amputation, or cardiovascular events could not be made. Cilostazol versus pentoxifylline There was no difference detected between cilostazol and pentoxifylline for improving walking distance, both in terms of ICD (MD 20.0 metres, 95% CI -2.57 to 42.57; 417 participants; one study; low-certainty evidence); and ACD (MD 13.4 metres, 95% CI -43.50 to 70.36; 866 participants; two studies; very low-certainty evidence). One study reported on QoL; the study authors reported no difference in QoL between the treatment groups (very low-certainty evidence). No study reported on revascularisation, amputation or cardiovascular events. Cilostazol participants had an increased odds of experiencing headache compared with participants taking pentoxifylline at 24 weeks (OR 2.20, 95% CI 1.16 to 4.17; 982 participants; two studies; low-certainty evidence). AUTHORS' CONCLUSIONS: Cilostazol has been shown to improve walking distance in people with intermittent claudication. However, participants taking cilostazol had higher odds of experiencing headache. There is insufficient evidence about the effectiveness of cilostazol for serious events such as amputation, revascularisation, and cardiovascular events. Despite the importance of QoL to patients, meta-analysis could not be undertaken because of differences in measures used and reporting. Very limited data indicated no difference between cilostazol and pentoxifylline for improving walking distance and data were too limited for any conclusions on other outcomes.

Successful Catheter-Directed Thrombolysis for Acute Lower Limb Ischemia Secondary to COVID-19 Infection.

A 49-year-old man was admitted to his local hospital with left leg pain and breathing difficulties. He had negative nasopharyngeal polymerase chain reaction tests for severe acute respiratory syndrome coronavirus 2. Chest X-ray and Computed tomography pulmonary angiogram displayed typical coronavirus disease 2019 (COVID-19) radiological features as ground-glass opacities and bronchovascular thickening. His respiratory symptoms resolved after four days of supportive treatment, whereas his left leg became more painful and discolored. He was referred to our center with acute left leg ischemia. computed tomography angiogram revealed eccentric mural thrombus at the aortic bifurcation, extending into left common iliac and an abrupt occlusion of left popliteal, tibioperoneal, and posterior tibial arteries. He was treated with catheter-directed thrombolysis for 48-hours that achieved successful revascularization of the ischemic limb with no intervention-related complications. At six-week follow-up, he showed full recovery. Our case demonstrates that catheter-directed thrombolysis is a successful and safe treatment option in a COVID-19 patient with acute arterial occlusion.

Cardiovascular and Renal Morbidity in Takayasu Arteritis: A Population-Based Retrospective Cohort Study From the United Kingdom.

OBJECTIVE: Cardiovascular disease (CVD) is a major complication and cause of mortality in Takayasu arteritis (TAK), but population-based controlled studies from the UK are lacking. We undertook the present study to investigate the frequency of morbidity and mortality related to CVD, as well as to cerebrovascular and kidney disease, among patients with TAK in the UK. METHODS: Yearly cohort and cross-sectional studies were performed from 2000 to 2017 to estimate annual incidence and prevalence, respectively, of TAK. Using a UK primary care database (IQVIA Medical Research Data), an open retrospective matched cohort study was conducted to estimate risk of hypertension, diabetes, cardiovascular morbidity, chronic kidney disease (CKD), and all-cause mortality in TAK. Risk (adjusted hazard ratio [HR]) of the assessed comorbidities among patients with TAK compared to age- and sex-matched controls was estimated. Changes in medication prescription over time were examined in both groups. RESULTS: One hundred forty-two patients with TAK (median age 53.4 years [interquartile range 33.8-70.7]) and 1,371 matched controls were included. The annual incidence and prevalence of TAK were 0.8 per million and 7.5 per million respectively. All-cause mortality was increased in TAK (adjusted HR 1.88 [95% confidence interval 1.29-2.76]). Patients with TAK had an increased risk of developing ischemic heart disease, stroke/transient ischemic attack, combined CVD, and peripheral vascular disease compared to controls, but no increase in risk of hypertension, CKD, heart failure, or diabetes. Only ~50% of patients with TAK requiring secondary CVD prevention were prescribed statins or antiplatelet agents within 1 year after study entry. CONCLUSION: Cardiovascular morbidity was increased among patients with TAK receiving primary care services in the UK. Treatment with statins and antiplatelet agents in these patients was suboptimal.

Digital Ischemia in COVID-19 Patients: Case Report.

As coronavirus 2019 (COVID-19) continues to cause an immense burden on the global health care systems, it is crucial to understand the breadth of this disease process. Recent reports identified hypercoagulability in a subset of critically ill patients and extremity ischemia in an even smaller cohort. Because abnormal coagulation parameters and extremity ischemia have been shown to correlate with poor disease prognosis, understanding how to treat these patients is crucial. To better describe the identification and management of this phenomenon, we present 2 cases of critically ill patients with COVID-19 who developed fingertip ischemia while in the intensive care unit.

Effects of modified Wenjing decoction on microcirculation in reproductive organs in rats with symptom patterns of cold coagulation and blood stasis.

OBJECTIVE: To investigate the relationship between symptom patterns of cold coagulation and blood stasis (CCBS) and microcirculation disturbance. In addition, we determined the efficacy of modified Wenjing decoction (WJD) for the treatment of CCBS. METHODS: CCBS was induced in rats with an ice-water bath treatment. The ovarian function, microvascular and circulatory status of reproductive organs, and function of local microvascular endothelial cells (VECs) and vascular smooth muscle cells (VSMCs) were evaluated. RESULTS: Ovarian dysfunction was observed in the rats with CCBS. It was characterized by the presence of an estrous cycle disorder and a decrease in reproductive hormone levels. Microvascular circulation disorders were associated with an imbalance in vasoconstriction, relaxation substances, nitric oxide, abnormal blood flow in whole blood, and decreased blood flow in the auricle and uterus. VECs were damaged, and VSMCs contracted and proliferated in ovarian and uterine tissues. CONCLUSION: Our findings suggest that the dysfunctional reproductive organs observed in gynecological CCBS may be closely related to the microcirculation disturbance of local tissues, microvascular contraction, and vascular remodeling. Modified WJD can be used to treat CCBS by improving microcirculation in reproductive organs.

Experience of a 40-day (6 week) LMWH treatment for isolated distal deep vein thrombosis.

Clinical significance of distal deep vein thrombosis (DVT) is important as it can potentially result in pulmonary embolism (PE), DVT extension, DVT recurrence and post-thrombotic syndrome (PTS). Controversy remains about the necessity and modalities of anticoagulation in all distal DVT. Evaluation of the efficiency of a 40-day weight-based low molecular weight heparin (LMWH) treatment in a cohort of 119 consecutive patients with distal DVT. Compression ultrasonography of the lower limb was performed initially for diagnosis as well as at the end of the treatment to identify persistence or resolution of the blood clot. A 3-month follow-up estimated the rates of PE, DVT recurrence, DVT extension, PTS and bleeding. Risk factors for DVT were considered to evaluate a possible correlation between them and the outcomes. In 71.4% of the patients the blood clot was totally dissolved and thrombus persistence was statistically associated with the number of initially involved veins. DVT recurrence occurred in 5% of patients and was also associated with the number of initial clotted veins. DVT extension and PTS rates were present in 1.7% and 3.4% respectively and no patient was diagnosed with PE or bleeding. This retrospective study including a limited number of patients and no control group supports that a 40-day weight-based LMWH treatment after distal DVT seems to be efficient when one single vein is initially affected whereas for multiple vein distal DVT and to avoid potential DVT recurrence, longer than 6 weeks of anticoagulant treatment is required. Our results support safety of the treatment, its potential to prevent DVT extension and the occurrence of PE.

Targeting Uremic Toxins to Prevent Peripheral Vascular Complications in Chronic Kidney Disease.

Chronic kidney disease (CKD) exhibits progressive kidney dysfunction and leads to disturbed homeostasis, including accumulation of uremic toxins, activated renin-angiotensin system, and increased oxidative stress and proinflammatory cytokines. Patients with CKD are prone to developing the peripheral vascular disease (PVD), leading to poorer outcomes than those without CKD. Cumulative evidence has showed that the synergy of uremic milieu and PVD could exaggerate vascular complications such as limb ischemia, amputation, stenosis, or thrombosis of a dialysis vascular access, and increase mortality risk. The role of uremic toxins in the pathogenesis of vascular dysfunction in CKD has been investigated. Moreover, growing evidence has shown the promising role of uremic toxins as a therapeutic target for PVD in CKD. This review focused on uremic toxins in the pathophysiology, in vitro and animal models, and current novel clinical approaches in reducing the uremic toxin to prevent peripheral vascular complications in CKD patients.

Botulinum Toxin A Salvage of Ischemic Hand Trauma.

Posttraumatic hand injuries from crush injury, infusion, or iatrogenic vascular cannulation can cause ischemic finger damage that can progress to necrosis and digital amputation. Botulinum toxin type A (Botox) improves blood flow in chronic vasospastic disorders of the hand. Botox's efficacy in salvaging ischemic loss in digits in acute traumatic and iatrogenic injury has not been previously reported. From February of 2015 to December of 2016, 11 patients at a Level I trauma center (West Virginia University) presented to the hand surgery service with early ischemic injury and vascular compromise to hand and fingers as a result of crush, direct drug injection, or proximal arterial injury from drug injection or catheterization. Before 2015, all patients with vascular compromise were treated with standard protocol. After January of 2016, patients were treated with additional injection of 80 to 100 U of Botox into the palm and wrist. Before administration of Botox, six patients with vascular compromise of one or more fingers were treated with a conservative protocol and 83 percent had amputation of necrotic digits. After January of 2016, five patients with ischemia were treated with Botox into the palm and proximal arteries. All Botox-treated digits were preserved (100 percent salvage). Pain scores were lower in Botox-treated fingers. We conclude that (1) in the acute traumatic vascular hand injury, early Botox injection markedly increases digital salvage; (2) direct nerve effects after Botox injections improve postinjury pain scores; and (3) early use of Botox in finger injuries is our standard approach to impending ischemia in the hand.

The History of Testosterone and the Evolution of its Therapeutic Potential.

INTRODUCTION: Testosterone therapy has been controversial since its synthesis in the 1930s to the present day. Testosterone's history provides depth and context for current controversies. AIM: To review the history of testosterone therapy from its initial synthesis in the 1930s to the modern day. METHODS: Expert review of the literature. MAIN OUTCOME MEASURES: Impactful events in the history of testosterone. RESULTS: By the 1940s there was already a fascinating literature that described the many symptomatic benefits of testosterone therapy that are recognized today. Numerous early reports suggested testosterone therapy improved angina pectoris and peripheral vascular disease. The assertion by Huggins and Hodges (Cancer Res 1941;1:293-297) in 1941 that testosterone activated prostate cancer (PCa) cast a pall for the next 70 years. The introduction of the radioimmunoassay in the 1970s shifted the diagnosis of testosterone deficiency from signs and symptoms to an undue emphasis on blood test results. The fear of PCa was the primary obstacle to the adoption of testosterone therapy for decades. Prescription rates increased as accumulated evidence showed testosterone therapy was not associated with increased PCa risks. The observation that androgenic stimulation of PCa reaches a maximum at relatively low testosterone concentrations-the saturation model-provided the theoretical framework for understanding the relation between androgens and PCa and led to multiple case series documenting reassuring results of testosterone therapy in men with PCa. Recent concerns regarding cardiovascular risks also have diminished because new evidence suggests testosterone therapy might actually be cardioprotective. In 2016 the Testosterone Trials provided high-quality evidence of multiple benefits of testosterone therapy, nearly all of which had been recognized by clinicians by 1940. CONCLUSIONS: If the past has any lessons for the future, it is likely that research will continue to demonstrate health benefits of testosterone therapy, while it remains one of the most controversial topics in medicine.

Guideline-directed therapies for comorbidities and clinical outcomes among individuals with atrial fibrillation.

BACKGROUND: Comorbidities are common in patients with atrial fibrillation (AF) and affect prognosis, yet are often undertreated. However, contemporary rates of use of guideline-directed therapies (GDT) for non-AF comorbidities and their association with outcomes are not well described. METHODS: We used the Outcomes Registry for Better Informed Treatment of AF (ORBIT-AF) to test the association between GDT for non-AF comorbidities and major adverse cardiac or neurovascular events (MACNE; cardiovascular death, myocardial infarction, stroke/thromboembolism, or new-onset heart failure), all-cause mortality, new-onset heart failure, and AF progression. Adjustment was performed using Cox proportional hazards models and logistic regression. RESULTS: Only 6,782 (33%) of the 20,434 patients eligible for 1 or more GDT for non-AF comorbidities received all indicated therapies. Use of all comorbidity-specific GDT was highest for patients with hyperlipidemia (75.6%) and lowest for those with diabetes mellitus (43.1%). Use of "all eligible" GDT was associated with a nonsignificant trend toward lower rates of MACNE (HR 0.90 [0.79-1.02]) and all-cause mortality (HR 0.90 [0.80-1.01]). Use of GDT for heart failure was associated with a lower risk of all-cause mortality (HR 0.77 [0.67-0.89]), and treatment of obstructive sleep apnea was associated with a lower risk of AF progression (OR 0.75 [0.62-0.90]). CONCLUSIONS: In AF patients, there is underuse of GDT for non-AF comorbidities. The association between GDT use and outcomes was strongest in heart failure and obstructive sleep apnea patients where use of GDT was associated with lower mortality and less AF progression.

Effects of simultaneous pancreas-kidney transplantation and kidney transplantation alone on the outcome of peripheral vascular diseases.

BACKGROUND: The effects of Simultaneous Pancreas Kidney Transplantation (SPKT) on Peripheral Vascular Disease (PVD) warrants additional study and more target focus, since little is known about the mid- and long-term effects on the progression of PVD after transplantation. METHODS: 101 SPKT and 26 Kidney Transplantation Alone (KTA) recipients with insulin-dependent diabetes mellitus (IDDM) were retrospectively evaluated with regard to graft and metabolic outcome. Special subgroup analysis was directed towards the development and progression of peripheral vascular complications (PVC) (amputation, ischemic ulceration, lower extremity angioplasty/ bypass surgery) after transplantation. RESULTS: The 10-year patient survival was significantly higher in the SPKT group (SPKT: 82% versus KTA 40%; P < 0.001). KTA recipients had a higher prevalence of atherosclerotic risk factors, including coronary artery disease (P < 0.001), higher serum triglyceride levels (P = 0.049), higher systolic (P = 0.03) and diastolic (P = 0.02) blood pressure levels. The incidence of PVD before transplantation was comparable between both groups (P = 0.114). Risk factor adjusted multivariate analysis revealed that patients with SPKT had a significant lower amount (32%) of PVCs (32 PVCs in 21 out of 101 SPKT; P < 0.001) when compared to the KTA patients who developed a significant increase in PVCs to 69% of cases (18 PVCs in 11 out of 26 KTA; P < 0.001). In line mean values of HbA1c (P < 0.01) and serum triglycerides (P < 0.01) were significantly lower in patients with SPKT > 8 years after transplantation. CONCLUSION: SPKT favorably slows down development and progression of PVD by maintaining a superior metabolic vascular risk profile in patients with IDDM1.

[PEGASUS or COMPASS? A guide for a wise clinical choice.] / PEGASUS o COMPASS? Una guida per una scelta clinica oculata.

The recent publication of the PEGASUS and COMPASS studies could have a great influence on the clinical management of patients with stable ischemic heart disease. In the presence of possible eligibility for both approaches, a practical tool based on inclusion/exclusion criteria of the two studies could be useful for clinical decision of ideal treatment for suitable patients. We therefore report a simple nomogram helpful in identifying the treatment indicated on the base of patient's characteristics.

Ecklonia Cava Extract Attenuates Endothelial Cell Dysfunction by Modulation of Inflammation and Brown Adipocyte Function in Perivascular Fat Tissue.

It is well known that perivascular fat tissue (PVAT) dysfunction can induce endothelial cell (EC) dysfunction, an event which is related with various cardiovascular diseases. In this study, we evaluated whether Ecklonia cava extract (ECE) and pyrogallol-phloroglucinol-6,6-bieckol (PPB), one component of ECE, could attenuate EC dysfunction by modulating diet-induced PVAT dysfunction mediated by inflammation and ER stress. A high fat diet (HFD) led to an increase in the number and size of white adipocytes in PVAT; PPB and ECE attenuated those increases. Additionally, ECE and PPB attenuated: (i) an increase in the number of M1 macrophages and the expression level of monocyte chemoattractant protein-1 (MCP-1), both of which are related to increases in macrophage infiltration and induction of inflammation in PVAT, and (ii) the expression of pro-inflammatory cytokines (e.g., tumor necrosis factor-α (TNF-α) and interleukin (IL)-6, chemerin) in PVAT which led to vasoconstriction. Furthermore, ECE and PPB: (i) enhanced the expression of adiponectin and IL-10 which had anti-inflammatory and vasodilator effects, (ii) decreased HFD-induced endoplasmic reticulum (ER) stress and (iii) attenuated the ER stress mediated reduction in sirtuin type 1 (Sirt1) and peroxisome proliferator-activated receptor γ (PPARγ) expression. Protective effects against decreased Sirt1 and PPARγ expression led to the restoration of uncoupling protein -1 (UCP-1) expression and the browning process in PVAT. PPB or ECE attenuated endothelial dysfunction by enhancing the pAMPK-PI3K-peNOS pathway and reducing the expression of endothelin-1 (ET-1). In conclusion, PPB and ECE attenuated PVAT dysfunction and subsequent endothelial dysfunction by: (i) decreasing inflammation and ER stress, and (ii) modulating brown adipocyte function.

Five-year real-world outcomes of anti-vascular endothelial growth factor monotherapy versus combination therapy for polypoidal choroidal vasculopathy in a Chinese population: a retrospective study.

BACKGROUND: To evaluate 5-year outcomes of anti-vascular endothelial growth factor (VEGF) monotherapy and combination therapy of anti-VEGF agents and photodynamic therapy (PDT) for polypoidal choroidal vasculopathy (PCV) in a real-world Chinese population. METHODS: Retrospective study. Fifty-three eyes of 46 patients with subtype 1 and 2 PCV followed up for at least 60 months were grouped into three regimens: anti-VEGF monotherapy, PDT combining with anti-VEGF therapy initially, and PDT combining with deferred anti-VEGF therapy. Main outcome measure was best-corrected visual acuity (BCVA) using logarithm of minimal angle of resolution (logMAR). RESULTS: The mean BCVA of eyes with subtype 1 PCV (n = 28) deteriorated from 0.69 logMAR at baseline to 1.25 logMAR at months 60 (P = 0.001), while the mean BCVA of eyes with subtype 2 PCV (n = 25) sustained stable from 0.62 logMAR at baseline to 0.57 at months 60 (P = 0.654). No significant differences of visual outcomes were found between the 3 treatment regimens for subtype 1 PCV. Anti-VEGF monotherapy and initial combination treatment had better visual outcomes in eyes with subtype 2 PCV than deferred combination group during part of follow-up significantly. Initial combination group needed a less number of PDT than deferred combination group (P < 0.001). CONCLUSIONS: Compared with subtype 1 PCV, subtype 2 PCV has a more favorable visual outcome in real world. All the regimens presented unfavorable visual outcomes for subtype 1 PCV. Anti-VEGF monotherapy and initial combination therapy should be superior to deferred combination therapy in the long-term management of subtype 2 PCV. Prospective randomized studies of larger size are needed to determine the long-term efficacy and safety of various treatment for PCV in real world.

Pharmacological interventions for painful sickle cell vaso-occlusive crises in adults.

BACKGROUND: Sickle cell disease (SCD) is a group of inherited disorders of haemoglobin (Hb) structure in a person who has inherited two mutant globin genes (one from each parent), at least one of which is always the sickle mutation. It is estimated that between 5% and 7% of the world's population are carriers of the mutant Hb gene, and SCD is the most commonly inherited blood disorder. SCD is characterized by distorted sickle-shaped red blood cells. Manifestations of the disease are attributed to either haemolysis (premature red cell destruction) or vaso-occlusion (obstruction of blood flow, the most common manifestation). Shortened lifespans are attributable to serious comorbidities associated with the disease, including renal failure, acute cholecystitis, pulmonary hypertension, aplastic crisis, pulmonary embolus, stroke, acute chest syndrome, and sepsis. Vaso-occlusion can lead to an acute, painful crisis (sickle cell crisis, vaso-occlusive crisis (VOC) or vaso-occlusive episode). Pain is most often reported in the joints, extremities, back or chest, but it can occur anywhere and can last for several days or weeks. The bone and muscle pain experienced during a sickle cell crisis is both acute and recurrent. Key pharmacological treatments for VOC include opioid analgesics, non-opioid analgesics, and combinations of drugs. Non-pharmacological approaches, such as relaxation, hypnosis, heat, ice and acupuncture, have been used in conjunction to rehydrating the patient and reduce the sickling process. OBJECTIVES: To assess the analgesic efficacy and adverse events of pharmacological interventions to treat acute painful sickle cell vaso-occlusive crises in adults, in any setting. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online, MEDLINE via Ovid, Embase via Ovid and LILACS, from inception to September 2019. We also searched the reference lists of retrieved studies and reviews, and searched online clinical trial registries. SELECTION CRITERIA: Randomized, controlled, double-blind trials of pharmacological interventions, of any dose and by any route, compared to placebo or any active comparator, for the treatment (not prevention) of painful sickle cell VOC in adults. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed studies for eligibility. We planned to use dichotomous data to calculate risk ratio (RR) and number needed to treat for one additional event, using standard methods. Our primary outcomes were participant-reported pain relief of 50%, or 30%, or greater; Patient Global Impression of Change (PGIC) very much improved, or much or very much improved. Our secondary outcomes included adverse events, serious adverse events, and withdrawals due to adverse events. We assessed GRADE and created three 'Summary of findings' tables. MAIN RESULTS: We included nine studies with data for 638 VOC events and 594 participants aged 17 to 42 years with SCD presenting to a hospital emergency department in a painful VOC. Three studies investigated a non-steroidal anti-inflammatory drug (NSAID) compared to placebo. One study compared an opioid with a placebo, two studies compared an opioid with an active comparator, two studies compared an anticoagulant with a placebo, and one study compared a combination of three drugs with a combination of four drugs. Risk of bias across the nine studies varied. Studies were primarily at an unclear risk of selection, performance, and detection bias. Studies were primarily at a high risk of bias for size with fewer than 50 participants per treatment arm; two studies had 50 to 199 participants per treatment arm (unclear risk). Non-steroidal anti-inflammatory drugs (NSAID) compared with placebo No data were reported regarding participant-reported pain relief of 50% or 30% or greater. The efficacy was uncertain regarding PGIC very much improved, and PGIC much or very much improved (no difference; 1 study, 21 participants; very low-quality evidence). Very low-quality, uncertain results suggested similar rates of adverse events across both the NSAIDs group (16/45 adverse events, 1/56 serious adverse events, and 1/56 withdrawal due to adverse events) and the placebo group (19/45 adverse events, 2/56 serious adverse events, and 1/56 withdrawal due to adverse events). Opioids compared with placebo No data were reported regarding participant-reported pain relief of 50% or 30%, PGIC, or adverse events (any adverse event, serious adverse events, and withdrawals due to adverse events). Opioids compared with active comparator No data were reported regarding participant-reported pain relief of 50% or 30% or greater. The results were uncertain regarding PGIC very much improved (33% of the opioids group versus 19% of the placebo group). No data were reported regarding PGIC much or very much improved. Very low-quality, uncertain results suggested similar rates of adverse events across both the opioids group (9/66 adverse events, and 0/66 serious adverse events) and the placebo group (7/64 adverse events, 0/66 serious adverse events). No data were reported regarding withdrawal due to adverse events. Quality of the evidence We downgraded the quality of the evidence by three levels to very low-quality because there are too few data to have confidence in results (e.g. too few participants per treatment arm). Where no data were reported for an outcome, we had no evidence to support or refute (quality of the evidence is unknown). AUTHORS' CONCLUSIONS: This review identified only nine studies, with insufficient data for all pharmacological interventions for analysis. The available evidence is very uncertain regarding the efficacy or harm from pharmacological interventions used to treat pain related to sickle cell VOC in adults. This area could benefit most from more high quality, certain evidence, as well as the establishment of suitable registries which record interventions and outcomes for this group of people.
