Cerebral small vessel disease (cSVD) has a crucial role in lacunar stroke and brain hemorrhages and is a leading cause of cognitive decline and functional loss in elderly patients. Based on underlying pathophysiology, cSVD can be subdivided into amyloidal and non-amyloidal subtypes. Genetic factors of cSVD play a pivotal role in terms of unraveling molecular mechanism. An important pathophysiological mechanism of cSVD is blood-brain barrier leakage and endothelium dysfunction which gives a clue in identification of the disease through circulating biological markers. Detection of cSVD is routinely carried out by key neuroimaging markers including white matter hyperintensities, lacunes, small subcortical infarcts, perivascular spaces, cerebral microbleeds, and brain atrophy. Application of neural networking, machine learning and deep learning in image processing have increased significantly for correct severity of cSVD. A linkage between cSVD and other neurological disorder, such as Alzheimer’s and Parkinson’s disease and non-cerebral disease, has also been investigated recently. This review draws a broad picture of cSVD, aiming to inculcate new insights into its pathogenesis and biomarkers. It also focuses on the role of deep machine strategies and other dimensions of cSVD by linking it with several cerebral and non-cerebral diseases as well as recent advances in the field to achieve sensitive detection, effective prevention and disease management.

The optimal management of patients with asymptomatic carotid stenosis (ACS) is the subject of extensive debate. According to the 2017 European Society for Vascular Surgery guidelines, carotid endarterectomy should (Class IIa; Level of Evidence: B) or carotid artery stenting may be considered (Class IIb; Level of Evidence: B) in the presence of one or more clinical/imaging characteristics that may be associated with an increased risk of late ipsilateral stroke (e.g., silent embolic infarcts on brain computed tomography/magnetic resonance imaging, progression in the severity of ACS, a history of contralateral transient ischemic attack/stroke, microemboli detection on transcranial Doppler, etc.), provided documented perioperative stroke/death rates are <3% and the patient’s life expectancy is >5 years. Besides these clinical/imaging characteristics, there are additional individual, ethnic/racial or social factors that should probably be evaluated in the decision process regarding the optimal management of these patients, such as individual patient needs/patient choice, patient compliance with best medical treatment, patient sex, culture, race/ethnicity, age and comorbidities, as well as improvements in imaging/operative techniques/outcomes. The present multispecialty position paper will present the rationale why the management of patients with ACS may need to be individualized.

Cardiovascular disease (CVD) related mortality and morbidity heavily strain society. The relationship between external risk factors and our genetics have not been well established.It is widely acknowledged that environmental influence and individual behaviours play a significant role in CVD vulnerability, leading to the development of polygenic risk scores (PRS). We employed the PRISMA search method to locate pertinent research and literature to extensively review artificial intelligence (AI)-based PRS models for CVD risk prediction.Furthermore, we analyzed and compared conventional vs. AI-based solutions for PRS. We summarized the recent advances in our understanding of the use of AI-based PRS for risk prediction of CVD. Our study proposes three hypotheses: i) Multiple genetic variations and risk factors can be incorporated into AI-based PRS to improve the accuracy of CVD risk predicting. ii) AI-based PRS for CVD circumvents the drawbacks of conventional PRS calculators by incorporating a larger variety of genetic and non-genetic components, allowing for more precise and individualised risk estimations. iii) Using AI approaches, it is possible to significantly reduce the dimensionality of huge genomic datasets, resulting in more accurate and effective disease risk prediction models. Our study highlighted that the AI-PRS model outperformed traditional PRS calculators in predicting CVD risk. Furthermore, using AI-based methods to calculate PRS may increase the precision of risk predictions for CVD and have significant ramifications for individualized prevention and treatment plans.

Herbal medicines are becoming more popular and acceptable day by day due to
their effectiveness, limited side effects, and cost-effectiveness. Cholistani plants are reported
as a rich source of antibacterial, antifungal, antiprotozoal, antioxidant, and anticancer agents.
The current study has evaluated antiviral potential of selected Cholistani plants. The whole
plants were collected, ground and used in extract formation with n-hexane, ethyl acetate and
n-butanol. All the extracts were concentrated by using a rotary evaporator and concentrate
was finally dissolved in an appropriate vol of the same solvent. All of the extracts were tested
for their antiviral potential by using 9-11 days old chick embryonated eggs. Each extract was
tested against the Avian Influenza virus H9N2 strain (AIV), New Castle Disease virus Lasoota
strain (NDV), Infectious bronchitis virus (IBV) and an Infectious bursal disease virus (IBDV).
Hemagglutination test (HA) and Indirect Hemagglutination (IHA) tests were performed for
different viruses. The overall order of the antiviral potential of Cholistani plants against
viruses was NDV>IBV>IBDV>AIV. In terms of antiviral activity from extracts, the order of
activity was n-butanol>ethyl acetate>n-hexane. The medicinal plants Achyranthes aspera,
Neuroda procumbens, Panicum antidotale, Ochthochloa compressa and Suaeda fruticose
were very effective against all four poultry viruses through their extracts. The low IC50
values of these extracts confirm the high antiviral potential against these viruses. It is worth
to mention that Achyranthes aspera was found positive against IBDV through all its extracts
which overcome the problem of unavailability of any known drug against IBDV. In short, the
study proved that Cholistani plants are rich source of antiviral agent and their extracts can be
used as good source of antiviral drugs both in crude and in purified form.
