Background: Healthcare workers (HCWs) play a vital role in delivering care and are frequently exposed to the risk of acquiring infections within the hospital setting. Around 15% of hospitalized patients suffer from these infections globally. However, the role and awareness of HCWs in the transmission of hospital‐acquired infections (HAIs) or nosocomial infections is still unclear. This study aimed to evaluate the knowledge, attitude, and practices (KAP) toward high‐risk microbial infections among HCWs on a global scale to identify measures to address this problem.Method: A cross‐sectional descriptive study was conducted between 2022 and 2023, with HCWs selected as the study population. Data concerning KAP were collected through a self‐administered online survey questionnaire, using a nonprobability convenience sampling method. Descriptive statistics and regression analysis were used to analyze the data.Results: A total of 743 HCWs from various countries participated in the study, with the majority of respondents being doctors (64.9%). Data were mainly obtained from Saudi Arabia (26.78%), Iraq (25.84%), India (15.7%), the United States of America (15.2%), and Africa (Sudan, Nigeria) (13.98%). The frequency of good KAP scores among physicians (KAP: 82.5, 80.66, and 70.5), nurses (KAP: 74.1, 73.07, and 88.7), medical practitioners (KAP: 87.2, 77.58, and 75.1), and technicians (KAP: 76.1, 74.38, and 89.6) were obtained as mentioned. With respect to experience, HCWs showed good KAP scores in 1–5 years (KAP: 82.4, 83.3, and 74.1), 5–10 years (KAP: 80.6, 74.54, 83), 10–20 years (KAP: 74.7, 79.1, and 82.7), and >20 years (KAP: 84.6, 78.8, and 82.8) categories.Conclusion: This study suggests that HCWs have good KAP regarding infection prevention, but there is still room for improvement. Educational seminars and awareness programs can provide better adherence to barrier protection measures such as hand washing, use of gloves, and hand disinfection.

Dysfunction in the epithelium, breakdown of the blood–brain barrier, and consequent leukocyte and T-cell infiltration into the central nervous system define Vascular Multiple Sclerosis. Multiple sclerosis (MS) affects around 2.5 million individuals worldwide, is the leading cause of neurological impairment in young adults, and can have a variety of progressions and consequences. Despite significant discoveries in immunology and molecular biology, the root cause of MS is still not fully understood, as do the immunological triggers and causative pathways. Recent research into vascular anomalies associated with MS suggests that a vascular component may be pivotal to the etiology of MS, and there can be actually a completely new entity in the already available classification of MS, which can be called ‘vascular multiple sclerosis’. Unlike the usual other causes of MS, vascular MS is not dependent on autoimmune pathophysiologic mechanisms, instead, it is caused due to the blood vessels pathology. This review aims to thoroughly analyze existing information and updates about the scattered available findings of genetics, pro-angiogenetic factors, and vascular abnormalities in this important spectrum, the vascular facets of MS.

Background: Given that there is already evidence of a neural network that connects the brain and gut and that the gut microbiota actively modulates gut health, it is crucial to know which foods, supplements, and medications to use or avoid when treating any disease that causes dementia or cognitive impairment. Previous research has examined the relationships between vitamins, antibiotics, and gut microbiota and the correlations between these factors and dementia. The question arises of how these three factors interact together and if evidence suggests one element is more important than the others in the pathogenesis and development of dementia.Methods: The Preferred Reporting Items for Systematic Reviews and Meta‐Analysis (PRISMA) standards were followed when conducting this review. The papers' publication dates varied from (2012−2022). Cochrane/EMBASE, PEDro, and PubMed/Medline databases were searched. The precise terms “gut microbiota,” vitamins,” antibiotics,” and “dementia” were included in the search method, along with the conjunctions “OR” and “AND.”Results: Gut dysbiosis has a significant impact on cognition, brain function, and the development and progression of dementia. The two most popular probiotics used in studies linked to cognition benefits were Lactobacillus and Bifidobacterium. Numerous scales were used to evaluate cognition, but the mini‐mental state examination was the most popular, and the most prevalent impairment was Alzheimer's disease. The supplements with the most significant impact on gut microbiota were vitamin B‐12 and folic acid.Conclusion: This systematic review concluded that vitamins, gut microbiota and antibiotics have a close association with the development of dementia. More research is required to establish causality and elucidate the underlying mechanisms because there is still little evidence connecting the interactions of vitamins, medications, and microbiota with dementia. The complexity of interactions between genetics, lifestyle factors, and comorbidities, as well as the heterogeneity of dementia, may make it more challenging to interpret the findings.

Juvenile multiple sclerosis (JMS) is a rare but significant subtype of multiple sclerosis (MS) that affects a small percentage of patients under the age of 10 and 3–5% of all MS patients. Despite its rarity, JMS poses unique challenges in terms of diagnosis, treatment, and management, as it can significantly impact a child or adolescent’s physical, cognitive, and emotional development. JMS presents with a varying spectrum of signs and symptoms such as coordination difficulties and permanent cognitive dysfunctions and may include atypical clinical features such as seizures, acute disseminated encephalomyelitis, and optic neuritis, making diagnostic evaluations challenging. Whilst the biology of JMS shares similarities with adult-onset MS, there exist notable distinctions in disease progression, clinical manifestations, and ultimate prognoses. The International Pediatric MS Study Group (IPMSSG) was founded in 2005 to improve understanding of JMS, but there remains a lack of knowledge and guidelines on the management of this condition. This review summarizes the current knowledge on JMS, including its epidemiology, clinical presentations, diagnostic challenges, current treatment options, and outcomes. Current treatment options for JMS include disease-modifying therapies, but JMS can also result in impaired quality of life and psychiatric comorbidity, highlighting the need for comprehensive care for affected children. Through gathering and analyzing scattered studies and recent updates on JMS, the authors aim to address the gaps in current knowledge on JMS and provide an improved understanding of appropriate care for affected children. By doing so, this review hopes to contribute to improving the quality of life and outcomes for JMS patients.

Multiple sclerosis (MS) and myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS) share the symptom of fatigue, and might even coexist together. Specifically focusing on genetics, pathophysiology, and neuroimaging data, the authors discuss an overview of the parallels, correlation, and differences in fatigue between MS and ME/CFS along with ME/CFS presence in MS. Studies have revealed that the prefrontal cortex and basal ganglia regions, which are involved in fatigue regulation, have similar neuroimaging findings in the brains of people with both MS and ME/CFS. Additionally, in both conditions, genetic factors have been implicated, with particular genes known to enhance susceptibility to MS and CFS. Management approaches for fatigue in MS and ME/CFS differ based on the underlying factors contributing to fatigue. The authors also focus on the recent updates and the relationship between MS and sleep disorders, including restless legs syndrome, focusing on pathophysiology and therapeutic approaches. Latest therapeutic approaches like supervised physical activity and moderate-intensity exercises have shown better outcomes.
