Cerebrovascular disease is uncommon in patients with HIV, occurring in up to 1.9% of patients, 0.2% were presenting with transient ischemic attacks. The central nervous system is the first part of the body to be affected by the human immunodeficiency virus. This case report is a unique presentation of a 33-year-old male who presented with focal neurologic deficits that lasted for one hour with a background of promiscuous history. The patient was positive for HIV screening test and CD4 count and was started on a combination of antiretroviral therapy. This is the first documented case report in the Philippines. This case report demonstrates the need for a high index of suspicion for early detection of the cause in HIV-positive patients with recurrent transient ischemic attacks, given the high morbidity and mortality that is associated with this condition if delayed or undiagnosed.

Stroke remains a major cause of death and disability, highlighting the intimate relationship between cardiovascular and cerebrovascular disease. Despite substantial advances in diagnosis and treatment, marked disparities in access to care and clinical outcomes continue to exist. As such, stroke remains a shared challenge for primary care physicians, cardiologists, and neurologists, emphasizing the need for effective prevention, timely intervention, structured rehabilitation, and optimal secondary prevention. In this issue, we feature the Executive Summary of the 2024 Clinical Practice Guidelines on the Management of Acute Ischemic Stroke and Intracerebral Hemorrhage in the Philippines, an important resource for promoting evidence-based, patient-centered care and improving stroke outcomes.

OBJECTIVES

The study aimed to define the cycle threshold (Ct) value of reverse transcription polymerase reaction (RT PCR) as a potential marker in identifying the risk of COVID-19-confirmed patients in developing cerebrovascular disease (CVD) and to present the risk factors associated with such occurrence.

The researcher employed a single center, retrospective, chart review, case-control study among adult RT-PCR confirmed, hospitalized COVID-19 patients at Las Piñas General Hospital and Satellite Trauma Center (LPGH STC) from January to December 2021. The study included 252 patients among 730 RT-PCR-confirmed adult COVID-19 patients who met the study population criteria.

Fifty patients had concomitant CVD, while 202 patients were non-CVD. The majority (n=143, 56.75%) were 19-59 years old male predominance (n=138, 54.76%). More than half of the study population suffered from either hypertension, diabetes, or both, with a high proportion of the subjects being non-compliant or no maintenance medications. Two hundred ten (83.3%) out of 252 patients were unvaccinated. Twenty (7.9%) patients were noted with a history of smoking, and 58 (23%) patients with a history of alcohol intake. The majority of the patients suffered moderate COVID-19 severity during their hospital stay, with a 30.16% (n=76) mortality rate. Ischemic stroke was the most common CVD, with 38 (76%) occurrences. Acute respiratory failure was the leading cause of death, followed by ARDS, brainstem failure, and ACS. The median cycle threshold among CVD patients was 32.84, significantly higher than the majority at 28.64. A higher mean Ct value was noted among patients with CVD infarct at 33.44 as compared to 26.83 among patients with Hemorrhagic Stroke. Utilizing the Point-Biserial Correlation Coefficient to analyze possible association between the Ct value and the occurrence of stroke, a 0.22 correlation coefficient implied a weak positive correlation between the Ct value and CVD occurrence.

The relationship between the cycle threshold (Ct) value and the occurrence of CVD exists weakly, and factors that might affect this relationship must be addressed and resolved. Interpreting Ct value results also requires clinical context; hence, careful utilization of such data must always be observed. Several factors, including old age, male gender, co existing comorbidities such as hypertension and diabetes mellitus, lack of maintenance medication and noncompliance, vaccination status, smoking, and alcohol intake history, contributed to the poorer outcome of the patients and the high probability of having a stroke.

OBJECTIVE: To explore the genetic etiology of a child with Brain small vessel disease 1 with ocular anomalies. METHODS: A child who was admitted to Ningbo Women and Children's Hospital on May 28, 2022 was selected for the study. Clinical data were collected, and peripheral blood samples from the child and her parents were obtained for genomic DNA extraction. Whole exome sequencing (WES) was performed to screen for pathogenic variants. Candidate variants were validated via Sanger sequencing and subjected to bioinformatic analysis. This study was approved by the Medical Ethics Committee of Ningbo Women and Children's Hospital (Ethics No. EC2020-014). RESULTS: The child was a 7-year-old female with a diagnosis of epilepsy. WES revealed that she has carried a heterozygous missense variant in the COL4A1 gene: c.1792G>A (p.Gly598Ser). Sanger sequencing confirmed that her parents both had the wild-type genotype for this variant. Based on American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants, the variant were predicted to be a likely pathogenic (PS2+PM1+PM2_Supporting+PP3). Bioinformatics predicted that amino acid 598 was highly conserved in different species, formed hydrogen bond with Asp599 after becoming Ser598. CONCLUSION The heterozygous missense variant of the COL4A1 gene c.1792T>C (p.G598S) could be the pathogenic cause of this child with Brain small vessel disease 1 with ocular anomalies.

Hypotension is a leading cause of age-related cognitive impairment. The available literature evidences that vascular factors are associated with dementia and that hypotension alters cerebral perfusion flow and can aggravate the neurodegeneration of Alzheimer's disease (AD). Despite the discovery of biomarkers and the recent progress made in neurovascular biology, epidemiology, and brain imaging, some key issues remain largely unresolved: the potential mechanisms underlying the neural deterioration observed in AD, the effect of cerebrovascular alterations on cognitive deficits, and the positive effects of hypotension treatment on cognition. Therefore, further well-designed studies are needed to unravel the potential association between hypotension and cognitive dysfunction and reveal the potential benefits of hypotension treatment for AD patients. Here, we review the current epidemiological, pathobiological, and treatment-related literature on neurovascular changes and hypotension-related cognitive dysfunction and highlight the unsettled but imminent issues that warrant future research endeavors.

BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

BACKGROUND: Inflammation plays a critical role in severe cerebral venous thrombosis (CVT) pathogenesis, but the benefits of anti-inflammatory therapies remain unclear. This study aimed to investigate the association between steroid therapy combined with anticoagulation and the prognosis of acute/subacute severe CVT patients. METHODS: A prospective cohort study enrolled patients with acute/subacute severe CVT at Xuanwu Hospital (July 2020-January 2024). Patients were allocated into steroid and non-steroid groups based on the treatment they received. Functional outcomes (modified Rankin scale [mRS]) were evaluated at admission, discharge, and 6 months after discharge. Serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), cerebrospinal fluid (CSF) IL-6, and intracranial pressure were measured at admission and discharge in the steroid group. Fundoscopic Frisén grades were assessed at admission and 6 months after discharge. Univariate and multivariate logistic regression were used to evaluat associations between steroid use and favorable outcomes (mRS ≤2) at the 6-month follow-up. Paired tests assessed changes in hs-CRP and other variables before and after treatment, and Spearman's correlations were used to analyze relationships between these changes and functional improvements. RESULTS: A total of 107 and 58 patients in the steroid and non-steroid groups, respectively, were included in the analysis. Compared with the non-steroid group, the steroid group had a higher likelihood of achieving an mRS score of 0-2 (93.5% vs . 82.5%, odds ratio [OR] = 2.98, P  = 0.037) at the 6-month follow-up. After adjusting for confounding factors, the result remained consistent. Pulsed steroid therapy did not increase mortality during hospitalization or follow-up, nor did it lead to severe steroid-related complications (all P  >0.05). Patients in the steroid group showed a significant reduction in serum hs-CRP, IL-6, CSF IL-6, and intracranial pressure at discharge compared to at admission, as well as a significant reduction in the fundoscopic Frisén grade at the 6-month follow-up compare to at admission (all P  <0.001). A reduction in serum inflammatory marker levels during hospitalization positively correlated with improvements in functional outcomes ( P  <0.05). CONCLUSION: Short-term steroid use may be an effective and safe adjuvant therapy for acute/subacute severe CVT when used alongside standard anticoagulant treatments, which are likely due to suppression of the inflammatory response. However, these findings require further validation in randomized controlled trials. TRAIL REGISTRATION ClinicalTrials.gov , NCT05990894.

This comprehensive review synthesizes the latest advancements in understanding inflammatory disorders affecting cerebral small vessels, a distinct yet understudied category within cerebral small vessel diseases (SVD). Unlike classical SVD, these inflammatory conditions exhibit unique clinical presentations, imaging patterns, and pathophysiological mechanisms, posing significant diagnostic and therapeutic challenges. Highlighting their heterogeneity, this review spans primary angiitis of the central nervous system, cerebral amyloid angiopathy-related inflammation, systemic vasculitis, secondary vasculitis, and vasculitis in autoinflammatory diseases. Key discussions focus on emerging insights into immune-mediated processes, neuroimaging characteristics, and histopathological distinctions. Furthermore, this review underscores the importance of standardized diagnostic frameworks, individualized immunomodulation approaches, and novel targeted therapies to address unmet clinical demands.

The incidence of cardiovascular diseases (CVD) together with their associated risk factors increasingly impact public health. According to the data provided in the 2024 Annual Report on Cardiovascular Health and Diseases in China, the crude incidence of cardiovascular and cerebrovascular diseases among Chinese residents aged ≥18 years, including acute myocardial infarction (AMI), angina pectoris treated by percutaneous transluminal coronary angioplasty/stent implantation and/or coronary artery bypass grafting, stroke, and sudden cardiac death was 620.33 per 100,000 population, with 87.6 for AMI. Stroke had an incidence of 491.0 per 100,000 population. The prevalence of adult coronary heart disease (CHD, aged ≥18 years) was 758 per 100,000 population. The CVD mortality in 2021 remained the highest, exceeding that of cancer and other causes. The crude mortality rate of CVD in 2021 was 364.16 per 100,000 population in rural areas and 305.39 per 100,000 population in urban areas. The crude mortality rates of cerebrovascular diseases and CHD among urban and rural residents in 2021 were 140.02 and 175.58, 135.08 and 148.19 per 100,000 population, respectively. In addition to interpreting the key findings of CVD incidence and mortality in China, we also update the data of associated risk factors, including tobacco use, physical activity, diet and nutrition, overweight and obesity, hypertension, dyslipidemia, diabetes, chronic kidney disease, sleep and psychological factors, environmental factors, and the diagnostic conditions of CVD diseases, aiming to provide a scientific foundation for advancing CVD prevention and control, and to inform relevant public health policy development.
