BMJ (Clinical Research Ed.) Jun 2024To investigate the incidence of cardiovascular disease (CVD) overall and by age, sex, and socioeconomic status, and its variation over time, in the UK during 2000-19.
OBJECTIVE
To investigate the incidence of cardiovascular disease (CVD) overall and by age, sex, and socioeconomic status, and its variation over time, in the UK during 2000-19.
DESIGN
Population based study.
SETTING
UK.
PARTICIPANTS
1 650 052 individuals registered with a general practice contributing to Clinical Practice Research Datalink and newly diagnosed with at least one CVD from 1 January 2000 to 30 June 2019.
MAIN OUTCOME MEASURES
The primary outcome was incident diagnosis of CVD, comprising acute coronary syndrome, aortic aneurysm, aortic stenosis, atrial fibrillation or flutter, chronic ischaemic heart disease, heart failure, peripheral artery disease, second or third degree heart block, stroke (ischaemic, haemorrhagic, and unspecified), and venous thromboembolism (deep vein thrombosis or pulmonary embolism). Disease incidence rates were calculated individually and as a composite outcome of all 10 CVDs combined and were standardised for age and sex using the 2013 European standard population. Negative binomial regression models investigated temporal trends and variation by age, sex, and socioeconomic status.
RESULTS
The mean age of the population was 70.5 years and 47.6% (n=784 904) were women. The age and sex standardised incidence of all 10 prespecified CVDs declined by 19% during 2000-19 (incidence rate ratio 2017-19 2000-02: 0.80, 95% confidence interval 0.73 to 0.88). The incidence of coronary heart disease and stroke decreased by about 30% (incidence rate ratios for acute coronary syndrome, chronic ischaemic heart disease, and stroke were 0.70 (0.69 to 0.70), 0.67 (0.66 to 0.67), and 0.75 (0.67 to 0.83), respectively). In parallel, an increasing number of diagnoses of cardiac arrhythmias, valve disease, and thromboembolic diseases were observed. As a result, the overall incidence of CVDs across the 10 conditions remained relatively stable from the mid-2000s. Age stratified analyses further showed that the observed decline in coronary heart disease incidence was largely restricted to age groups older than 60 years, with little or no improvement in younger age groups. Trends were generally similar between men and women. A socioeconomic gradient was observed for almost every CVD investigated. The gradient did not decrease over time and was most noticeable for peripheral artery disease (incidence rate ratio most deprived least deprived: 1.98 (1.87 to 2.09)), acute coronary syndrome (1.55 (1.54 to 1.57)), and heart failure (1.50 (1.41 to 1.59)).
CONCLUSIONS
Despite substantial improvements in the prevention of atherosclerotic diseases in the UK, the overall burden of CVDs remained high during 2000-19. For CVDs to decrease further, future prevention strategies might need to consider a broader spectrum of conditions, including arrhythmias, valve diseases, and thromboembolism, and examine the specific needs of younger age groups and socioeconomically deprived populations.

High Prevalence of F2 20210G > A in Splanchnic Vein Thrombosis and Cerebral Venous Sinus Thrombosis: A Retrospective Cohort Study of Patients with Thrombosis in Atypical Sites.
INTRODUCTION
Atypical sites for thrombosis include deep vein thrombosis (DVT) of the upper extremity (UE-DVT), splanchnic vein thrombosis (SVT), and cerebral venous sinus thrombosis (CVST). In addition to specific pathogenic factors, their underlying mechanisms share similarities with typical venous thromboembolism (VTE), namely, DVT of the lower extremity and/or pulmonary embolism, but are less understood.
METHODS
Records of unselected patients with a history of typical VTE ( = 2,011), UE-DVT ( = 117), SVT ( = 83), and CVST ( = 82), who were referred to the Institute in Bonn for ambulatory thrombophilia testing, were retrospectively analyzed. Acquired and hereditary thrombosis risk factors were comparatively assessed.
RESULTS
UE-DVT was characterized by a high rate (50.4%) of site-specific acquired risk factors. Compared with typical VTE, SVT was more frequently associated with systemic inflammation, infection, or malignancy (2.2 vs. 12.0%, = 3·10) and the V617F mutation was present in 16.9%. In CVST compared with typical VTE, demographics and higher rates of oral contraception (43.2 vs. 57.6%, = 0.011) and pregnancy (4.2 vs. 10.9%, = 0.012) suggest a significant hormonal influence on etiology. While the prevalence of inhibitor deficiencies and factor V Leiden mutation did not differ between cohorts, the prevalence of 20210G > A was higher in SVT (15.7%, = 0.003) and CVST (15.9%, = 0.003) than in typical VTE (7.0%).
CONCLUSION
The cohorts with thrombosis in atypical sites showed distinctive patterns of acquired risk factors. Further studies are warranted to provide additional mechanistic insight into the role of hormonal influence in CVST and the contribution of 20210G > A to the development of SVT and CVST.

Current Diagnostic and Therapeutic Approaches in May-Thurner Syndrome in Children, Adolescents, and Young Adults: A Survey among Thrombosis Experts of the German Society of Thrombosis and Haemostasis.
May-Thurner syndrome (MTS) is a pelvic venous disorder involving compression of the left common iliac vein by the right common iliac artery, which results in predisposition for deep vein thrombosis. Although MTS is increasingly recognized in young patients, specific guidelines on diagnosis and management for children, adolescents, and young adults do not exist so far. The aim of this study was to assess current diagnostic and therapeutic practice in Germany, Austria, and Switzerland in children and young adults with thrombosis and MTS.We designed an online survey with 11 questions, which we sent via a mailing list to all members of the German, Austrian, and Swiss Society of Thrombosis and Haemostasis Research. Between July and October 2022, 33 specialists answered the questionnaire. Most participating specialists worked at pediatric hospitals (61%). Numbers of annually treated thromboses ranged from <5 (26%) to >30 (13%). Most specialists used venous ultrasound to diagnose deep vein thrombosis, 53% magnetic resonance imaging. Only 25% of specialists systematically screened for MTS in deep vein thrombosis. MTS was managed with anticoagulation (65%), iliac vein stent placement (32%), or balloon angioplasty (13%). In total, 31% of specialists reported to use more than one therapeutic method. Diagnostic and therapeutic approaches for MTS differed between specialists. Lack of standardization resulted in individualized and highly diverse management. Prospective observational clinical studies investigating the outcome of different management strategies including long-term follow-up on outcome and incidence of postthrombotic syndrome will help in defining patient groups who benefit most from revascularizing interventional strategies and developing standardized guidelines.

OBJECTIVES
Deep Vein Thrombosis (DVT) is a significant medical concern characterized by the formation of blood clots within the venous system. Surgical procedures are known to increase the risk of DVT. While enoxaparin has proven to be highly effective in treating DVT, concerns about bleeding and accurate dosage regulation may restrict its application. Recent research has focused on aspirin's potential in preventing DVT after various surgeries. This study aimed to determine whether aspirin was as effective as enoxaparin in preventing DVT after spine surgery.
METHODS
This randomized controlled trial enrolled study patients who underwent spine surgery at Shahid Kamyab Emergency Hospital in Mashhad, and had a Caprini score > 5, indicating a higher risk of DVT. In the control group, patients received subcutaneous injections of enoxaparin at a dosage of 40 mg, while the intervention group received oral aspirin tablets with a daily dosage of 81 mg. An experienced radiologist performed a Doppler ultrasound of the lower limbs' veins seven days after surgery to diagnose DVT. The outcomes of the two groups were then compared.
RESULTS
A total of 100 patients participated in the clinical trial and were equally assigned to the aspirin and enoxaparin groups. Both groups were homogeneous regarding the basic and clinical characteristics. The incidence of postoperative DVT was 4.0% in the aspirin group and 10.0% in the enoxaparin group (p=0.092). The incidence of hemorrhage was 2.0% in the aspirin group and 4.0% in the enoxaparin group (p=0.610).
CONCLUSION
These findings indicate that aspirin may be a promising alternative to enoxaparin for DVT prevention after surgery, but additional research is essential to validate these results and further assess the benefits and risks associated with aspirin usage in this context.

Review
BACKGROUND
Periacetabular osteotomy (PAO) is a well-established surgical treatment for hip dysplasia, but very few studies report the impact of peri-operative management strategies on early pain and function. The purpose of this study is to describe peri-operative management variability among a group of experienced surgeons and review the literature supporting these practice patterns.
METHODS
We surveyed 16 surgeons that perform PAO to document various aspects of peri-operative management at four stages: pre-operative, intra-operative, post-operative in the hospital, and at discharge. Our goal was to report current surgical pain management strategies, adjunct medications, type of anesthesia, deep venous thrombosis and heterotopic ossification prophylaxis strategies, initiation of physical therapy, and use of continuous passive motion (CPM). We reviewed current literature to identify studies supporting these perioperative strategies and identify knowledge gaps that would benefit from further investigation.
RESULTS
Of the 16 surgeons surveyed, 75% had been in practice greater than 10 years and most had not altered their post-operative protocol for more than 3 years. 15/16 surgeons felt that length of stay could be reduced at their institution with improved peri-operative pain management. 6/16 were considering or had already implemented outpatient PAO as a part of their practice. We found significant variability in the pain medications provided at all peri-operative stages. 14/16 utilized general anesthesia, and many utilized epidural or peripheral nerve blocks. 6/16 surgeons utilized surgical field block (also referred to as periarticular block). These surgeons advocated that surgical field block was an effective intervention with no/minimal complication risk. There is very little literature critically evaluating efficacy of these perioperative management strategies for PAO.
CONCLUSION
There is significant practice variability in peri-operative management of PAO surgery. We report various strategies utilized by a group of experienced surgeons and review supporting literature. There are significant knowledge gaps in best surgical pain management strategies, adjunct medications, surgical field blocks, and use of CPM that need further investigation. .

BACKGROUND
The COVID-19 pandemic related to SARS-CoV-2 virus was responsible for global pandemic. The severe form of the disease was linked to excessive activation of immune pathways together with a systemic cytokine storm response and thrombotic venous or arterial complications. Factors predicting severe outcomes including venous and/or pulmonary thrombosis (VT) and death were identified, but the prognostic role of their combination was not addressed extensively.
OBJECTIVES
We investigated the role of prognostic factors from the coagulation or inflammatory pathways to better understand the outcome of the disease.
METHODS
For this, we prospectively studied 167 SARS-CoV-2-positive patients from admission in intensive care units (ICU) or emergency departments from four academic hospitals over a 14-month period. Besides standard biology, we assessed serum concentrations of inflammatory markers, coagulation factors and peripheral blood cells immunophenotyping.
RESULTS
Thirty-nine patients (23.3%) developed VT and 30 patients (18%) died. By univariate analysis, C-reactive protein (CRP) level > 150 mg/L, interleukin-6 (IL-6) ≥ 20 pg/mL, D-dimers > 1,500 μg/L, ADAMTS13 activity ≤ 50%, Von.
CONCLUSION
A combination of coagulation and inflammatory markers can refine the prognostication of severe outcome in COVID-19, and could be useful for the initial evaluation of other types of viral infection.

BACKGROUND
Although rare, cerebral venous sinus thrombosis (CVT) can result in significant neurological complications, particularly after childbirth. Early diagnosis poses a challenge due to symptom overlap with other conditions. Limited publications and underdiagnosis of CVT are prevalent in developing nations, notably in Ethiopia.
CASE
A 29-year-old mother, having given birth four times, presented to the emergency department in her second month postpartum with complaints of persistent headaches and blurred vision over three weeks. Additionally, she reported sudden weakness on her right side for one day. Despite previous treatments for migraine headaches, she was diagnosed with CVT after magnetic resonance imaging/venography revealed blockage in the right anastomotic vein and the posterior segment of the superior sagittal sinus. Treatment commenced with the anticoagulant enoxaparin. During hospitalization, she experienced one episode of generalized seizures, leading to transfer to the intensive care unit where phenytoin was added. Subsequent diagnosis of papilledema occurred. After a 16-day hospital stay, she was discharged with warfarin, phenytoin, and acetazolamide. Oral anticoagulation and other medications ceased after six months of treatment, considering the postpartum period as a temporary risk factor for CVT. The patient currently maintains good health and has resumed normal activities.
CONCLUSION
Maintaining a high index of suspicion for CVT during the postpartum period and promptly conducting imaging scans are crucial for early diagnosis. This approach can halt neurological decline and facilitate immediate recovery through early therapeutic interventions.

INTRODUCTION
A hemodialysis tunneled catheter is one option for vascular access used with hemodialysis patients; however, catheter complications such as thrombosis are still inevitable. To prevent thrombosis formation, a catheter-locking solution is instilled between dialysis sessions. Heparin is used as a default locking solution in our Hemodialysis Care Project centers, while a recombinant tissue plasminogen activator (rt-PA) such as alteplase is used to treat suspected catheter thrombosis. This study aimed to identify the clinical factors, catheter brands, and hemodialysis variables that influence the choice of use for alteplase versus heparin, for those patients with tunneled catheters, and reduce overprescribing of high-alert medication alteplase.
METHODS
A retrospective medical chart review study was conducted involving 230 patients with tunneled catheters; the first group of 133 patients used alteplase regularly three times a week, while the second group of 97 patients completed at least one year using the same catheter access with heparin lock only.
RESULTS
Multivariate logistic regression and logistic regression analysis showed a significant association (p < 0.05) between different variables. Results suggest that overweight and hyperlipidemia patients are more likely to use alteplase. Patients using brand-name catheters such as Hemostar/Vas-cath (BD, Franklin Lakes, NJ) are less likely to use heparin than those using Medcomp catheters (Medcomp, Yuma, AZ). In addition, patients having a history of angioplasty would be less likely to have heparin than no angioplasty. Moreover, if the patient's fluid removal were equal to or less than 2 kg, they would be more likely to use heparin and vice versa.
CONCLUSION
The study postulates that identified variables affect whether alteplase or heparin is used in hemodialysis tunneled catheters, and may be useful to increase awareness, improve practices, or judiciously control the use of alteplase within Saudi Arabia and globally.

Review
Dengue, commonly referred to as 'breakbone fever,' is a mosquito-borne arboviral infection transmitted by , featuring an average incubation period of approximately seven days. Key cytokines such as interferon-gamma (IFN-γ), tumor necrosis factor (TNF)-α, and interleukin (IL)-10 are pivotal in the pathogenesis of dengue. Travelers are particularly susceptible to contracting dengue fever, with disease severity often associated with CD8+ T cell response. Without proper hospitalization during severe cases like dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS), mortality rates can escalate to 50%. Dengue fever can lead to various complications, including neurological manifestations such as encephalopathy, encephalitis, cerebral venous thrombosis, myelitis, posterior reversible encephalopathy syndrome, strokes (both ischemic and hemorrhagic), immune-mediated neurological syndromes (such as mononeuropathy, acute transverse myelitis, Guillain-Barre syndrome, and acute disseminated encephalomyelitis), and neuromuscular complications. Treatment protocols typically involve assessing disease activity using composite indices, pursuing treatment objectives, and administering intravenous fluids according to symptomatology. Given the absence of specific antiviral treatment for dengue, supportive care, particularly hydration, remains paramount during the early stages. It is crucial to recognize that dengue viruses may contribute to the development of neurological disorders, particularly in regions where dengue is endemic. Furthermore, there is a necessity for well-defined criteria for specific neurological complications. Primary prevention strategies primarily revolve around vector control measures, which play a critical role in curtailing the spread of dengue.

To use Optical Coherence Tomography (OCT) to measure scleral thickness (ST) and subfoveal choroid thickness (SFCT) in patients with Branch Retinal Vein Occlusion (BRVO) and to conduct a correlation analysis. A cross-sectional study was conducted. From May 2022 to December 2022, a total of 34 cases (68 eyes) of untreated unilateral Branch Retinal Vein Occlusion (BRVO) patients were recruited at the Affiliated Eye Hospital of Nanchang University. Among these cases, 31 were temporal branch vein occlusions, 2 were nasal branch occlusions, and 1 was a superior branch occlusion. Additionally, 39 cases (39 eyes) of gender- and age-matched control eyes were included in the study. Anterior Segment Optical Coherence Tomography (AS-OCT) was used to measure ST at 6 mm superior, inferior, nasal, and temporal to the limbus, while Enhanced Depth Imaging Optical Coherence Tomography (EDI-OCT) was used to measure SFCT. The differences in ST and SFCT between the affected eye, contralateral eye, and control eye of BRVO patients were compared and analyzed for correlation. The axial lengths of the BRVO-affected eye, contralateral eye, and control group were (22.92 ± 0.30) mm, (22.89 ± 0.32) mm and (22.90 ± 0.28) mm respectively, with no significant difference in axial length between the affected eye and contralateral eye (P > 0.05). The SFCT and ST measurements in different areas showed significant differences between the BRVO-affected eye, contralateral eye in BRVO patients (P < 0.05). The CRT of BRVO-affected eyes was significantly higher than that of the contralateral eyes and the control eyes (P < 0.001). In comparison between BRVO-affected eyes and control eyes, there were no statistically significant differences in age and axial length between the two groups (P > 0.05). However, significant differences were observed in SFCT and temporal, nasal, superior, and inferior ST between the two groups (P < 0.05). The difference in temporal ST between the contralateral eyes and the control eyes was not statistically significant (t = - 0.35, P = 0.73). However, the contralateral group showed statistically significant increases in SFCT, nasal, superior and inferior ST compared to control eyes (t = - 3.153, 3.27, 4.21, 4.79, P = 0.002, 0.002, < 0.001, < 0.001). However, the difference between the CRT of the contralateral and control eyes was not statistically significant (P = 0.421). When comparing SFCT and ST between BRVO-affected eyes with and without macular edema, no statistically significant differences were found (t = - 1.10, 0.45, - 1.30, - 0.30, 1.00; P = 0.28, 0.66, 0.21, 0.77, 0.33). The thickness of SFCT and temporal ST in major BRVO group is higher than the macular BRVO group and the difference was statistically significant (t = 6.39, 7.17, P < 0.001 for all). Pearson correlation analysis revealed that in BRVO patients, there was a significant positive correlation between SFCT/CRT and temporal ST (r = 0.288, 0.355, P = 0.049, 0.04). However, there was no correlation between SFCT/CRT and nasal ST, superior ST, and inferior ST (P > 0.05). In BRVO patients, both SFCT/CRT and ST increase, and there is a significant correlation between SFCT/CRT and the ST at the site of vascular occlusion.
