Impact of Ambient Air Pollution with PM2.5 on Stroke Occurrence: Data from Kaunas (Lithuania) Stroke Register (2010–2022)

Background: Ambient particulate matter of ≤2.5 μm in diameter (PM2.5) is named as a risk factor for cerebrovascular diseases. This investigation aimed to evaluate the impact of ambient air pollution with PM2.5 on stroke occurrence. Methods: The study was performed in Kaunas, Lithuania, from 2010 to 2022. The daily numbers of ISs, subarachnoid hemorrhages (SAHs), and intracerebral hemorrhages (ICHs) were obtained from the Kaunas Stroke Register. The association between stroke occurrence and PM2.5 exposure was assessed by time- and seasonally stratified Poisson regression. Results: Among middle-aged persons, 3377 had a stroke, of which 2686 (79.5%) had an IS, 469 (13.9%) had an ICH, and 222 (6.6%) had SAH. The relative risk (RR) of SAH was increased by 1.7% with an increase in daily PM2.5 by 1 μg/m3 on the same day and at a lag of 1 day, and by 2.2% with an increase in mean PM2.5 concentration at a lag 0–1 days by 1 μg/m3. The RR of having a SAH was increased by 0.7% with an increase in daily PM2.5 by 1 μg/m3 on the same day. Conclusions: Significant associations between stroke occurrence and air pollution with PM2.5 were found in the SAH and HS patients, and only in middle-aged subjects.

Seasonal Variation in Vascular Dehydration Risk: Insights from the KOBE Study

Abstract Objectives Dehydration, a risk factor for ischemic cerebrovascular diseases, is common in summer; however, the incidence of ischemic diseases is not necessarily higher in summer. The phenomenon may be influenced by the differences in the susceptibility to vascular dehydration based on the season. Therefore, this study aimed to distinguish types of dehydration in colder and warmer seasons by analyzing serum osmolarity, hematocrit, and daily non-alcohol drink (NAD) intake. Methods Participants in the Kobe Orthopedic and Biomedical Epidemiologic (KOBE) Study, consisting of healthy individuals, were categorized into two groups based on the examination month: the warmer and colder seasons. Multivariate analyses were conducted to examine disparities in serum osmolarity, hematocrit, and NAD intake between these two groups. Results Participant ratios by age group and the seasons (warmer season/colder season) were as follows: Women under 50 (35/62), 50-60 (77/126), 60-70 (123/170), over 70 (58/52); Men under 50 (14/17), 50-60 (22/36), 60-70 (57/71), over 70 (55/34). The colder season was found to be negatively correlated with serum osmolarity and NAD intake, but positively correlated with hematocrit, even after adjusting for relevant factors. Age was independently associated with serum osmolarity, but not with hematocrit and NAD intake. Conclusions This study highlights that vascular dehydration is more likely in the colder season despite lower serum osmolarity than the warmer season. Age-related increases in serum osmolarity without a corresponding rise in water intake may contribute to this. These findings emphasize the importance of addressing dehydration in the colder season, particularly in older adults. Key messages • The colder season showed a negative correlation with serum osmolarity and NAD intake but a positive correlation with hematocrit. • Raising awareness about the importance of hydration during winter may be essential.

Trend in the prevalence, awareness, treatment and control of hypertension among adult over in Nigeria over a 4-year period

Abstract Background Hypertension is the commonest risk factor for most cardiovascular and cerebrovascular diseases, also the commonest cause of sudden unexpected death in the country. Despite concerted efforts to reduce the burden of this condition through increasing awareness, treatment and control rate of hypertension among adults in Nigeria. The rates of hypertension awareness (60%), treatment (34%), and control (12%) have been reported recently These figures need to change for the improved health of the citizens. Objective The study assessed the trend in the prevalence, levels of awareness, treatment, and control of hypertension among adults in urban setting in Nigeria, Sub-Sahara Africa. Methods This was a retrospective study. Data collected from opportunistic screening of adults aged 15 years and above in 4 urban communities during May Measurement Month from 2020 to 2023 was analyzed. Standardized protocol was used to collected data on socio-demographics and anthropometric measurements, blood pressure and pulse rate were measured using digital blood pressure monitors after patient have rested for at least 15 minutes. Hypertension was defined based on the 7th Report of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of Hypertension. Data was analyzed using SPSS 22 and p-value <0.05 was statistically significant Results We analyzed data of 2676participants. The mean age was 40.4years (SD 15·04), 68·5% of whom were women, 2.8% had diabetes mellitus, and 50·9% were overweight/obese. A third of the participants (33·9%) had hypertension, more than half of whom (57·2%) were aware that they were diagnosed of hypertension. The prevalence reduced from 39.7% in 2020 to 26.8% in 2023. Among those diagnosed, 66.5% were taking medication, and among those taking medication 32.5% had controlled blood pressure. We noted an increasing improvement in the rate of awareness from 35.4% to 72.5%, treatment from 46.7% to 82.6% and control from 5.7% to 52.3% over the 4-year period, p-value 0.000 (figure 1). When comparing between the hypertensives and non-hypertensives; higher age group (55years and above), the presence of diabetic mellitus and overweight/obesity showed statistically significant association, all at p-value of 0.000 each (table 1). Conclusion Hypertension is still a major problem among urban dwellers in Akwa Ibom State, with almost every one out of three adults have the condition. Though there is a decreasing trend in the prevalence and increasing trend in the awareness, treatment and control of hypertension, these rates are still suboptimal. Urgent measures are needed to reduce the prevalence and improve hypertension control among this population.

Migraine in antiphospholipid syndrome and hereditary thrombophilia: pregnancy-related clinical and diagnostic features and therapeutic issues

Introduction. Migraine is one of the most common primary headaches and a risk factor for cardiovascular and cerebrovascular diseases. Antiphospholipid syndrome (APS) and hereditary thrombophilia (HT) causing pathological pregnancy are highly associated with migraine. Timely migraine recognition related to APS and HT facilitates earlier initiation of thrombophilia pathogenetic therapy and prevention of potential complications.Aim: to analyze the literature data on migraine clinical and diagnostic features in APS and HT as well as pregnancy-related therapeutic issues.Materials and Methods. A search for scientific literature was conducted in electronic databases including PubMed, Google Scholar, eLibrary from 2004 until May 2024. The search methodological basis included the presence of the following keywords and their combinations in Russian and English: "migraine", "antiphospholipid syndrome", "thrombophilia", "migraine and pregnancy", "migraine and thrombophilia", "migraine and cardiovascular diseases". As a result, a total of 184 publications were identified. Next, 62 articles were included in the review.Results. At the current stage, neurologists have no means to diagnose migraine in APS and HT based on headache-intrinsic characteristics. Pregnancy increases a risk of thrombotic complications. A migraine observed in patient's history should be crucial while assessing pregnancy-related obstetric risk. While diagnosing migraine, neurologists need to examine patient obstetric history. The data on most effective and safe therapy for pregnancy-related migraine attacks remain scarce.Conclusion. The frequent association between APS and HT with migraine, the lack of clear migraine clinical features in thrombophilia, patients’ reproductive age, and the high risk of thrombotic complications necessitate collaboration between neurologists and obstetricians-gynecologists for timely diagnostics and management of such patients. The impact of various types of antithrombotic therapy on migraine course requires further clarification. It is promising to conduct studies able to determine of whether migraine attack prevention can avoid adverse pregnancy outcomes in women with former migraine.

Investigating the Predictive Biomethods. of Hypertension (HTN) in Human Foetal Astrocytes (HFAs) using Modified Proteomic Methods

Background: Hypertension (HTN) is a major risk factor for Cerebrovascular and cardiovas-cular diseases, causing premature deaths. Hence, there is an urgent need for predictive bi-omarkers to detect HTN before its onset. Methods • Cell Culture Technique: Growth of HFAs, followed by conversion of normal (A2) HFAs intoreactive (A1) type, by using ATP solution. • Confocal Microscopy: Quantification of Glial Fibrillary Acidic Protein (GFAP) in A1 and A2 HFAs, by using antibody ab 7260 with AF 488. Proteomics Methos • Extraction of proteins from A1 and A2 HFAs, using Single-pot, Sol-id-phase-enhanced Sample Preparation (SP3) protocol. • Liquid Chromatography- Mass Spectrometry techniques for obtaining the lev-els of calcium-gated proteins in A1 and A2 cell-solutions. Results • Micrographs obtained by Leica Microsystem indicated thicker filaments in A1 HFAs compared to A2 HFAs. • Confocal results showed higher levels of GFAP in A1 HFAs (P> 0.05). • Proteomics data analysed by PEAKS software revealed that proteins, such as GFAP were higher in reactive HFAs. Conclusions: The results showed higher levels of GFAP in A1 HFAs. Therefore, early detection of GFAP in human body fluids could be a reliable predictive biomarker for HTN

P225 RISK FACTORS FOR CEREBROVASCULAR DISEASE IN WOMEN ADMITTED TO THE INTERNAL MEDICINE SERVICE OF THE EMERGENCY DEPARTMENT OF THE CENTRAL HOSPITAL IN SAN CRISTOBAL (TACHIRA, VENEZUELA)

Background and objective: Cerebrovascular disease is a leading cause of mortality and disability worldwide. Research has focused on determining the risk factors for cerebrovascular disease independent of gender; however, it has been important to differentiate between men and women due to the variety of causes that occur in the latter. Therefore, the aim was to determine the risk factors for cerebrovascular disease in women admitted to the internal medicine service of the Central Hospital of San Cristóbal (Táchira, Venezuela). Methods: A case-control study was performed. Cases were female patients diagnosed with acute cerebrovascular disease (24 to 72 hours after symptom onset). Controls were hospitalized or community-based female subjects without pathologies associated with cardiovascular disorders. The case-control ratio was 1:2, of equal age or ± 5 years. All participants signed the informed consent form and completed the data collection form. Odds ratios (OR) were calculated, with 95% confidence intervals. Results: In the period between February 2 to July 15, 2020, 111 female participants entered the study, 37 cases (26 with ischemic cerebrovascular disease and 11 with hemorrhagic cerebrovascular disease) and 74 controls. Of the risk factors studied: arterial hypertension, diabetes mellitus, dyslipidemia, physical inactivity, smoking, alcohol consumption, overweight, obesity, atrial fibrillation, use of oral contraceptives, use of hormone replacement therapy, autoimmune diseases, only association was found between atrial fibrillation (OR 9.1736, 95% CI 3.3638-25.0173), autoimmune diseases (OR 9.1736, 95% CI 3.3638-5.0173) and ischemic cerebrovascular disease. No association was found with any risk factor and hemorrhagic cerebrovascular disease. Conclusions: The risk factors for cerebrovascular disease in the female population are modifiable and treatable, being pertinent to determine their presence and carry out the necessary actions to reduce morbimortality in this population group.

A Rapid, Sensitive, and High-throughput Method for the Simultaneous Determination of Antihypertensive Drug Combinations in Dog Plasma by UHPLC-MS/MS: The Assessment of Predicable Bioequivalence of In-vitro Dissolution Condition.

Essential hypertension is a common clinical disease and a risk factor for cardiovascular and cerebrovascular diseases. Olmesartan medoxomil, amlodipine, and hydrochlorothiazide are commonly used antihypertensive drugs. The aim of this study was to establish a robust UPLC-MS/MS method for the simultaneous determination of olmesartan medoxomil, amlodipine, and hydrochlorothiazide in dog plasma. At the same time, the in vivo and in vitro release studies were conducted, and a preliminary in vitro-in vivo correlation (IVIVC) evaluation was performed. The bioequivalence experiment was conducted with a double-crossed design. Three major components were extracted and analyzed by UHPLC-MS/MS. With the MRM scan, olmesartan and amlodipine were quantified by fragment conversion (m/z 447.10→190.10) and (m/z 408.95→294.00) under positive ESI mode, while hydrochlorothiazide was quantified with fragment conversion (m/z 295.90→268.90) under negative ESI mode. The in vitro release studies were performed using a USP paddle, and the dissolution medium was chosen from pH 6.0 to pH 6.8 according to the BCS classification of compounds. The IVIVC was calculated using the Wagner-Nelson equation. The linear ranges of olmesartan, amlodipine, and hydrochlorothiazide in the plasma were 5.0-2500, 0.1-50, and 3.0-1500 ng/mL, respectively. All accuracies were within 3.8% of the target values, and the findings revealed that intra-day and inter-day accuracies were less than 12.1%. Moreover, the recoveries exceeded 88.3%, the matrix effect tests were positive, and the stability tests were positive. With the establishment of correlation, the distinguishable dissolution condition (pH 6.8) was selected as the predictable condition. The established method was suitable for the preclinical pharmacokinetic study of tripartite drugs with strong specificity and high sensitivity. Through the evaluation of IVIVC, the connection between in vivo and in vitro drug testing was initially established.

GGC repeat expansions in NOTCH2NLC cause uN2CpolyG cerebral amyloid angiopathy.

The expansion of GGC repeats within NOTCH2NLC leads to the translation of the uN2CpolyG protein, the primary pathogenic factor in neuronal intranuclear inclusion disease (NIID). This study aims to explore the deposition of uN2CpolyG as an amyloid in the vessel wall, leading to uN2CpolyG cerebral amyloid angiopathy (CAA)-related cerebral microbleeds (CMBs). A total of 97 patients with genetically confirmed NIID were enrolled in this study. We analyzed the presence of CMBs using susceptibility-weighted imaging sequences and compared general clinical information, cerebrovascular risk factors, stroke history, antiplatelet medication use, and MRI features between NIID patients with and without CMBs. We further performed hematoxylin and eosin (H&E), Perl's, Congo red, and Thioflavin S staining, ubiquitin, p62 and uN2CpolyG immunostaining on brain tissue obtained from four NIID patients. A total of 354 CMBs were detected among 41 patients with NIID, with nearly half located in the deep brain, one-third in the lobes, and approximately 20% in the infratentorial area. No significant differences in cerebrovascular disease risk factors or history of antiplatelet drug use were observed between patients with and without CMBs. However, patients with CMBs suffered a higher incidence of previous ischemic and hemorrhagic stroke events. This group also had a higher incidence of recent subcortical infarcts and a higher proportion of white matter lesions in the external capsule and temporal pole. Conversely, patients without CMBs showed higher detection of high signals at the corticomedullary junction on diffusion-weighted imaging and more pronounced brain atrophy. H&E staining showed blood vessel leakage and hemosiderin-laden macrophage clusters, and Prussian blue staining revealed brain tissue iron deposition. CMBs occurred more frequently in small vessels lacking intranuclear inclusions, and extensive degeneration of endothelial cells and smooth muscle fibres was observed mainly in vessels lacking inclusions. Congo red-positive amyloid deposition was observed in the cerebral vessels of NIID patients, with disordered filamentous fibres appearing under an electron microscope. Additionally, the co-localization of Thioflavin S-labeled amyloid and uN2CpolyG protein in the cerebral vascular walls of NIID patients further suggested that uN2CpolyG is the main pathogenic protein in this form of amyloid angiopathy. In conclusion, we reviewed patients with GGC repeat expansion of NOTCH2NLC from a novel perspective, providing initial clinical, neuroimaging, and pathological evidence suggesting that uN2CpolyG may contribute to a distinct type of CAA.

Early-onset palatal myoclonus in Wernekinck commissure syndrome secondary to caudal paramedian midbrain infarction: A case report and a mini review of the literature

IntroductionWernekinck commissure syndrome (WCS) is an extremely rare midbrain syndrome, which selectively destroys the decussation of the superior cerebellar peduncle and the central tegmental tract, which commonly presents with bilateral cerebellar ataxia, dysarthria, and internuclear ophthalmoplegia. Palatal myoclonus in Wernekinck commissure syndrome is uncommon and often occurs as a late phenomenon due to hypertrophic degeneration of bilateral inferior olivary nuclei. Material and methodA patient with WCS, admitted to our hospital from December 2023, was chosen for this study, and the syndrome's clinical manifestations, imaging features, and etiology were retrospectively analyzed based on the literature. A 68-year-old right-handed East Asian man presented with dizziness, slurred speech, difficulty with swallowing and walking, and rhythmic contractions of the soft palate. He had several risk factors for ischemic cerebrovascular diseases (age, sex, dyslipidemia, hypertension and smoking history). Brain magnetic resonance imaging showed hyperintensity of DWI and hypointensity of ADC at the caudal midbrain which was around the paramedian mesencephalic tegmentum anterior to the aqueduct of midbrain. ResultsHe was diagnosed with Wernekinck commissure syndrome (WCS) secondary to caudal paramedian midbrain infarction. He was started on dual antiplatelet therapy (aspirin and clopidogrel) and intensive statin therapy. Blood pressure and glucose were also adjusted. His symptoms improved rapidly, and he walked steadily and speak clearly after 7 days of treatment. ConclusionsPalatal myoclonus is known to occur as a late phenomenon due to hypertrophic degeneration of bilateral inferior olivary nuclei. However, Our case suggests that palatal myoclonus can occur in the early stages in WCS.

Awareness of risk factors for cerebrovascular diseases among acute ischemic stroke patients in Shenzhen, China

ABSTRACT Background and purpose Unawareness of the risk factors is one of the most important issues that need to be settled for stroke prevention. We aimed to evaluate the awareness of risk factors for cerebrovascular diseases (CVDs) among acute ischemic stroke patients and to investigate the characteristics of patients who were unaware of their risk factors in Shenzhen, China. Methods Registered data on awareness of CVD risk factors of patients with confirmed acute ischemic stroke (AIS) from June 2020 to December 2022 were analyzed in May 2023. The data were extracted from the database of Shenzhen Quality Control Center for Management of Cerebrovascular Diseases. Results Totally, there were 5147 AIS patients with complete data eligible for this study. AIS patients’ awareness regarding existing hypertension, diabetes, dyslipidemia, and atrial fibrillation (AF) was 76.1%, 76.2%, 24.2%, and 53.4%, respectively. Patients who were lack of awareness of the CVD risk factors were more likely to be males, individuals with younger ages, and those without medical insurance or a CVD history. Conclusions The overall awareness of the CVD risk factors was suboptimal among AIS patients in Shenzhen, especially for the existing dyslipidemia. The health education of AIS should be further improved in males as well as individuals without medical insurance or any CVD histories. Age was an independent factor associated with the lack of awareness of the CVD risk factors. The stroke screening program should be extended to younger people.

Sleep apnea after stroke: A novel target

Sleep apnea is an independent risk factor for cerebrovascular diseases. Its prevalence in stroke survivors is high and the disorder negatively affects patients' outcomes. Despite the importance of sleep apnea assessment is highlighted also in the current guidelines, a high proportion of patients remain undiagnosed and lose the potential benefit of positive airway pressure treatment. The current paper describes links between sleep apnea and stroke. It focuses on the challenges of the diagnostic and therapeutical process and provides a brief insight into ongoing trials that could help to identify appropriate diagnostic and therapeutic approaches, their timing, and the patient population for whom treatment could be most beneficial.

Overweight in Adolescence and Young Adulthood in Association With Adult Cerebrovascular Disease: The NFBC1966 Study.

Risk factors for cerebrovascular disease in adulthood are well known. However, research on individuals' risk factors throughout their life span has been limited. This prospective cohort study aims to determine the effect of body mass index (BMI) and its changes in adolescence and young adulthood on early onset cerebrovascular disease. This study includes 10 491 people (5185 women) from the Northern Finland Birth Cohort 1966. Height, weight, and BMI were measured at ages 14 and 31 years. Sex- and age-specific BMI ranges were used to define overweight and obesity. Data on ischemic and hemorrhagic cerebrovascular diseases between ages 14 and 54 years were extracted from national hospital and death registers. Cox proportion hazard models (95% CI) were used to estimate associations between BMI or its changes and cerebrovascular disease, while adjusting for sex, smoking, educational level, BMI at the other time point, and age at menarche for women. Additionally, sex-BMI interactions were calculated. A total of 452 individuals (4.7%) experienced cerebrovascular disease during the follow-up. The risk of ischemic cerebrovascular disease was increased for overweight women at ages 14 years (hazard ratio [HR], 2.49 [95% CI, 1.44-4.31]) and 31 years (HR, 2.13 [95% CI, 1.14-3.97]), as well as for obese women at ages 14 years (HR, 1.87 [95% CI, 0.76-4.58) and 31 years (HR, 2.67 [95% CI, 1.26-5.65]), with normal weight as the reference. These results were independent of earlier or later BMI. Similar associations were not found among men. The risk of hemorrhagic cerebrovascular disease was increased at age 31 years both among obese women (HR, 3.49 [95% CI, 1.13-10.7) and obese men (HR, 5.75 [95% CI, 1.43-23.1). The risk of any cerebrovascular disease related to overweight at age 14 years was 2.09× higher among girls than boys (95% CI, 1.06-4.15). The risk of ischemic cerebrovascular disease related to obesity at age 31 years was 6.96× higher among women than men (95% CI, 1.36-35.7). Among women, being overweight in adolescence or young adulthood increases the risk of cerebrovascular disease, especially ischemic, independent of their earlier or later BMI.

Neuroimaging and clinical features of bilateral Wallerian degeneration of middle cerebellar peduncles subsequent to pontine infarction.

Wallerian degeneration (WD) of the middle cerebellar peduncles (MCPs) following pontine infarction is a rare secondary degenerative neurological condition. Due to its infrequency, there is limited research on its characteristics. This study aims to present three cases of WD of MCPs following pontine infarction and to analyze the prognosis, clinical manifestations, and neuroimaging features by amalgamating our cases with previously reported ones. The cohort consisted of 25 cases, comprising 18 men and 7 women aged 29 to 77 years (mean age: 66.2 years). The majority of patients (94%) exhibit risk factors for cerebrovascular disease, with hypertension being the primary risk factor. Magnetic resonance imaging (MRI) can detect WD of MCPs within a range of 21 days to 12 months following pontine infarction. This degeneration is characterized by bilateral symmetric hyperintensities on T2/FLAIR-weighted images (WI) lesions in the MCPs. Moreover, restricted diffusion, with hyperintensity on diffusion-weighted imaging (DWI) and low apparent diffusion coefficient (ADC) signal intensity may be observed as early as 21 days after the infarction. Upon detection of WD, it was observed that 20 patients (80%) remained asymptomatic during subsequent clinic visits, while four (16%) experienced a worsening of pre-existing symptoms. These findings underscore the importance of neurologists enhancing their understanding of this condition by gaining fresh insights into the neuroimaging characteristics, clinical manifestations, and prognosis of individuals with WD of bilateral MCPs.

Analysis of health knowledge awareness and influencing factors of permanent residents in Songshan Lake Science and Technology Industrial Park, Dongguan City

Objective: To understand the health knowledge awareness and influencing factors of permanent residents in Songshan Lake Science and Technology Industrial Park, Dongguan City, and to provide a data basis for the development of health education and public health services in the region. Methods: A multi-stage stratified sampling method was used to select 1,000 permanent residents from 13 residential areas in the region as survey subjects. Basic demographic information and health knowledge awareness were obtained through questionnaires, and statistical analysis was conducted on the data. Results: The health knowledge awareness rate of permanent residents in the region is relatively low, with the highest rate being the dangers of smoking in pregnant women, with the correct answer rate reaching 87.1%. Correct use of antibiotics, transmission routes of AIDS, salt intake standards and hypertension diagnostic standards have correct answer rates between 40% and 55%. The three knowledge points of risk factors for hypertension, diabetes and cerebrovascular disease had the lowest correct answers. Respondents with higher education levels know more health knowledge. Conclusion:The awareness rate of health knowledge is very low, which is not suitable for the current economic development and population quality. Health education and publicity should be strengthened for groups with low awareness and knowledge content.

The antihyperlipidemic effects of coenzyme Q10 and gemfibrozil on hyperlipidemic male rats: a comparative study

Dyslipidemia is considered as the most common risk factor for cardiovascular diseases, cerebrovascular diseases, and fatty liver disease. The available therapy aimed to decrease lipid profile and reduced long-term risk which do require lifelong therapy, hence adverse effects are suggestive. The goal of the present study is to compare the anti¬hyperlipidemic influence and hepatic side effects of CoQ10 and gemfibrozil in the hyperlipidemic male rats model. Twenty-five albino rats were divided into 5 groups: group 1(normal group), group 2 (olive oil group), group 3(hyperlipidemia-induced group) group 4 (CoQ10-treated group), and group 5 (gemfibrozil-treated group). Induction of hyperlipidemia lasts for 90 days and treatment lasts for 30 days. Serum liver enzyme analysis and liver histological study conducted to demonstrate the safety profile of the treatment agents. Analysis of the data revealed that the lipid profile parameters (except HDL) and liver enzymes were significantly (p< 0.001) higher in the hyperlipidemic group (Group 3) compared to either the control group (Group 1) or olive oil group. Using CoQ10 (Group 4) and gemfibrozil (Group 5) has revealed that the lipid parameters and liver enzymes were significantly (p<0.001) lower compared to the hyperlipidemic group (Group 3). Compared to control group, liver showed congestion of sinusoids, severe necrosis of hepatocytes, vacuolar degradation, and infiltration of inflammatory cells, these effects reversed in presence of CoQ10. Compared to gemfibrozil, CoQ10 provides safer and equally effective option for treatment of dyslipidemia represented by improved lipid parameters and liver enzymes alongside protected hepatic architecture.

Ciliary neurotrophic factor promotes the development of homocysteine-induced vascular endothelial injury through inflammation mediated by the JAK2/STAT3 signaling pathway

Elevated homocysteine (Hcy) levels have been recognized as significant risk factor for cardiovascular and cerebrovascular diseases, closely related to endothelial injury. While expression of Ciliary Neurotrophic Factor (CNTF) significantly increases during Hcy-induced vascular endothelial cell injury, the precise molecular pathways through which CNTF operates remain to be clarified. To induce vascular endothelial cell injury, human umbilical vein endothelial cells (HUVECs) were treated with Hcy. Cell viability and apoptosis in HUVECs were assessed using the CCK-8 assay and flow cytometry. Western blot analysis determined the expression levels of the JAK2-STAT3 pathway, inflammation-related factors (IL-1β, NLRP3, ICAM-1, VCAM-1), and apoptosis-related factors (cleaved Caspase-3 and Bax). Immunofluorescence staining and western blotting were employed to examine CD31 and α-SMA expression. Knockdown of CNTF was achieved using lentiviral interference, and its effects on inflammation and cell injury were evaluated. Chromatin immunoprecipitation (ChIP) and dual luciferase reporter analysis were conducted to investigate the interaction between the MAFK and CNTF promoters. Our results indicated that Hcy induced high expression of CNTF and activated the JAK2-STAT3 signaling pathway, thereby upregulating factors associated with inflammation and cell apoptosis. Inhibiting CNTF alleviated Hcy-induced inflammation and cell injury. MAFK was identified as a transcription factor promoting CNTF transcription, and its overexpression exacerbated inflammation and cell injury in Hcy-treated HUVECs through the CNTF-JAK2-STAT3 axis, which could be reversed by knocking down CNTF. Activation of MAFK leads to CNTF upregulation, which activates the JAK2-STAT3 signaling pathway, regulating inflammation and inducing injury in Hcy-exposed vascular endothelial cells. Targeting CNTF or its upstream regulator MAFK may represent potential therapeutic strategies for mitigating endothelial dysfunction associated with hyperhomocysteinemia and cardiovascular diseases.

Care for the cerebrovascular accident survivors: experiences of family caregivers

BackgroundThe role of family caregivers in the management of cerebrovascular accident survivors is invaluable. So far, there is a strong evidence affirming the effectiveness of family support for cerebrovascular accident survivors. Meanwhile, caring for cerebrovascular survivors can be labour and time intensive and pretty stressful for caregivers. The purpose of the study was to examine the lived experiences of family caregivers of cerebrovascular accident survivors in the Ho Municipality in the Volta Region of Ghana. This aims are to establish their caregivers’ knowledge, preparedness, and impact of caregiving on the caregiver, and coping strategies caregivers adopted.MethodsUsing a four-item (with 14 prompts) interview guide and descriptive phenomenological approach, we gathered and analysed data from 37 family caregivers in the Ho Municipality of Ghana.ResultsWe found that caregivers had limited knowledge about cerebrovascular disease-risk factors and were ill-prepared for their caregiving roles. Additionally, we found limited knowledge about coping strategies among the caregivers. We further report that some caregivers lost close relationships, and their jobs because of the caregiving, they also used fasting and prayer as coping strategies.ConclusionsCaregivers suffered broken relationship, loss their jobs and incomes due to their caregiving roles. Moreover, some engaged in fasting and prayers, and alcohol use to cope with the stress associated with caring for the cerebrovascular accident survivors. We discussed the potential implications of our findings on the realisation of the Sustainable Development Goal 3.4. The aim of this goal is to reduce by 75% premature deaths due to cerebrovascular and other non-communicable diseases by 2030.

Prevalence of Hypertension and Its Associated Risk Factors Among Adults Attending Medical Outpatient Clinics at Ibn Sina General Hospital Authority in Mukalla City, Yemen.

Hypertension (HTN) is the most generally acknowledged modifiable risk factor for cardiovascular disease, cerebrovascular disease, and end-stage renal disease. Accordingly, the World Health Organization has listed HTN as the third greatest cause of death globally. The objective of this study was to assess the prevalence of HTN and its associated risk factors among adults attending medical clinics at Ibn Sina Hospital Authority in Mukalla City, Yemen. A cross-sectional descriptive survey was conducted using a self-administered questionnaire applied to 384 male and female adults aged ≥18 years attending Ibn Sina General Hospital Authority outpatient clinics in Mukalla City, Yemen, between December 2022 and May 2023. The participant's body weight, height, and waist circumference were measured. The data were analyzed using StatisticalPackage for the Social Sciences (IBMSPSSStatisticsforWindows,IBMCorp., Version 25.0, Armonk,NY). P values of <0.05 were considered statistically significant. Among the 384 participants, 20.5% had HTN, and the remaining (79.5%) did not have HTN, with a substantial proportion (47.2%) reporting a positive family history of HTN. Diabetes mellitus was present in 16.1% of the participants, whereas dyslipidemia and other chronic diseases were reported by 9.3% and 15.8% of the participants, respectively. A total of 75.6% of the participants had never smoked, and 11.7% were past smokers. More than half of the participants (57.29%) had never chewed khat, 20.57% were former khat chewers, and 22.14% were currently chewing khat. Nutritional status, as indicated by body mass index, showed that 29.8% were overweight. HTN was found to be prevalent among the study participants. However, the respondents' awareness of the problem and the overall control rates were very low. Certain factors, such as family history of HTN, diabetes mellitus, and high body mass index, were found to be associated with HTN. Therefore, intervention measures are warranted emphasizing modifiable risk factors to prevent HTN.

Modifiable Risk Factors Associated With Cognitive Decline in Late Life Depression: Findings From the Canadian Longitudinal Study on Aging: Facteurs de risque modifiables associés au déclin cognitif dans la dépression en fin de vie : constatations de l'Étude longitudinale canadienne sur le vieillissement.

Depression in later life is associated with a two-fold increased risk of dementia. It is not clear to what extent potentially modifiable risk factors account for this association. Older adults (age 50 + ) with objective health measures (n = 14,014) from the Canadian Longitudinal Study on Aging were followed for a mean duration of 35 months. Linear regression analyses were used to determine if clinically significant depression (Centre for Epidemiologic Studies Depression scale score (CESD) ≥ 10) was associated with global cognitive decline, assessed with a neuropsychological battery during follow-up, and if modifiable risk factors mediated this association. Depression was associated with an excess of risk factors for cognitive decline including: vascular disease, hypertension, diabetes, apnoea during sleep, higher body mass index, smoking, physical inactivity and lack of social participation. In regression analyses depression remained independently associated with cognitive decline over time (beta -0.060, P = 0.038) as did cerebrovascular disease (beta -0.197, P < 0.001), HbA1C (beta -0.059, P < 0.001), visual impairment (beta -0.070, P = 0.007), hearing impairment (beta -0.098, P < 0.001) and physical inactivity (beta -0.075, P = 0.014). In mediation analyses, we found that cerebrovascular disease (z = -3.525, P < 0.001), HbA1C (z = -4.976, P < 0.001) and physical inactivity (z = -3.998, P < 0.001) partially mediated the association between depression and cognitive decline. In this large sample of Canadian older adults incorporating several objective health measures, older adults with depression were at increased risk of cognitive decline and had an excess of potentially modifiable risk factors. Clinicians should pay particular attention to control of diabetes, physical inactivity and risk factors for cerebrovascular disease in older adults presenting with depression as they can contribute to accelerated cognitive decline and may be addressed during routine clinical care.

POSTERIOR REVERSIBILE LEUKOENCEPHALOPATHY SYNDROME AND HYPERTENSIVE CRISIS DUE TO OBSTRUCTIVE SLEEP APNEA:SEARCHING FOR A LINK

Objective: Posterior Reversible Encephalopathy Syndrome(PRES) is a clinic-radiological syndrome characterized by headache, nausea/vomiting, confusion, cognitive changes, seizures,cortical blindness. MRI shows bilateral hyper-intense lesions at the parieto-occipital sub-cortical level on T2 and FLAIR sequences. PRES is associated with severe hypertension, while obsstructive sleep apnesa(OSA) is a common cause of secondary hypertension but rarely causes hypertensive encephalopathy. We present a case of a 42-year-old woman who suffered of hypertensive emergency during hospitalization for dyspnea. Design and method: Clinical history revealed obesity, COPD, OSA in treatment with CPAP, HF with depressed EF (44%), adrenal hyperplasia and retroduodenal lesion under investigation. She was active smoker and BP was uncontrolled by valsartan 160 mg, furosemide 25 mg,bisoprolol 2,5 mg. During the hospitalization in November 2023, patient presented headache, seizures, respiratory distress with high BP values (220/120 mmHg, HR 78 bpm). Results: Laboratory tests revealed only a mild increase of plasma cortisol levels (27.5 mcg/dL, range 0-24); low-dose overnight dexamethasone suppression test was normal (1.5 mcg/dl). Despite anti-hypertensive therapy with B-blocker urinary metanephrine levels were normal (184 mcg/24 h, range 0-320) and 18f-FDG PET-TAC for retroduodenal lesion was normal. Cerebral CT did not show ischemic or hemorrhagic lesions while MRI documented radiological characteristics compatible with PRES (Figure 1). Electroencephalogram showed no epileptic abnormalities. Antihypertensive intravenous treatment with urapidil (25 mg as bolus injection followed by 25 mg/h as continuous infusion) was performed for 36h and followed by oral treatment with canrenoate 25 mg, amlodipine 5 mg and doxazosin 4 mg, added to the above therapy. At discharge, BP was normalized (120/84 mmHg). Checking the electronic card of CPAP, the patient used the device for more than four hours only in 35% of the nights. Conclusions: OSA is a risk factor for acute cardiovascular and cerebrovascular diseases like PRES. CPAP application has been shown to induce small reductions (about 3 mmHg) in BP, but in clinical practice the adherence of treatment is very low (30-60%). On the other hand, the improvement of BP values during hospitalization, raises the suspicion that adherence to pharmacological treatment at home was in the same way poor.
