INTRODUCTION: Previous studies suggest that low consumption as well as low serum levels of polyunsaturated fatty acids (PUFA) omega-3 and a high omega-6/omega-3 ratio may be implicated in the etiology of depressive disorders, however, epidemiologic evidence is inconclusive. OBJECTIVE: To assess the relationship of serum levels of omega-3 fatty acids (docosahexaenoic [DHA], eicosapentaenoic [EPA], alpha-linolenic fatty acid [ALA]) and the omega-6 (arachidonic acid [AA])/EPA ratio with depressive symptoms among Mexican college students...

BACKGROUND: Younger age, male sex and presence of spinal cord lesion(s) increase the risk of conversion from radiologically isolated syndrome (RIS) to relapsing-remitting multiple sclerosis (RRMS). Elevated cerebrospinal fluid (CSF) chitinase-3-like protein 1 (CHI3L1) levels predict conversion from clinically isolated syndrome (CIS) to RRMS. OBJECTIVE: To evaluate the prognostic value of CSF CHI3L1 in RIS patients for conversion to RRMS. METHODS: We compared CSF CHI3L1 concentrations in RIS, CIS, RRMS and symptomatic controls (SCs)...

Kawasaki disease (KD) is one of the most common childhood vasculitides and may lead to coronary arterial complications. KD has been reported in more than 60 countries over five continents. Previous publications have provided a comprehensive description of the epidemiologic features of KD including incidence, age of onset, seasonal trends, and rates of cardiac lesions. However, the interactions among the KD patients, time (seasons) and place have been less well studied. We review the current global epidemiology of KD and focus on the longitudinal changes in incidence, seasonality and response to intravenous immunoglobulin (IVIG) therapy...

Background: Hand, foot and mouth disease (HFMD) affects millions of children across Asia annually, leading to an increase in implemented control policies such as surveillance, isolation and social distancing in affected jurisdictions. However, limited knowledge of disease burden and severity causes difficulty in policy optimisation as the associated economic cost cannot be easily estimated. We use a data synthesis approach to provide a comprehensive picture of HFMD disease burden, estimating infection risk, symptomatic rates, the risk of complications and death, and overall disability-adjusted life-year (DALY) losses, along with associated uncertainties...

In the case of tuberculosis (TB), the capabilities of epidemic models to produce quantitatively robust forecasts are limited by multiple hindrances. Among these, understanding the complex relationship between disease epidemiology and populations' age structure has been highlighted as one of the most relevant. TB dynamics depends on age in multiple ways, some of which are traditionally simplified in the literature. That is the case of the heterogeneities in contact intensity among different age strata that are common to all airborne diseases, but still typically neglected in the TB case...

Both the incidence and the prevalence of dementia increase exponentially with increasing age. This raises the question of whether dementia is an inevitable consequence of aging or whether aging without dementia is achievable. In this review article, we sought to summarize the current evidence from epidemiological and neuropathological studies that investigated this topic. Epidemiological studies have shown that dementia could be avoided even at extreme old ages (e.g., centenarians or supercentenarians). Furthermore, clinico-neuropathological studies found that nearly half of centenarians with dementia did not have sufficient brain pathology to explain their cognitive symptoms, while intermediate-to-high Alzheimer pathology was present in around one-third of very old people without dementia or cognitive impairment...

Frailty, a critical intermediate status of the aging process that is at increased risk for negative health-related events, includes physical, cognitive, and psychosocial domains or phenotypes. Cognitive frailty is a condition recently defined by operationalized criteria describing coexisting physical frailty and mild cognitive impairment (MCI), with two proposed subtypes: potentially reversible cognitive frailty (physical frailty/MCI) and reversible cognitive frailty (physical frailty/pre-MCI subjective cognitive decline)...

Housing environments can directly and indirectly affect sleep, and blacks are more likely than whites to live in suboptimal housing conditions, which may independently contribute to sleep disparities. However, few large-scale epidemiological studies consider the potential influence of housing type on sleep health. Using data from the 2004-2015 National Health Interview Survey, we investigated overall and Black-White differences in the association between housing type (house/apartment versus mobile home/trailer) and sleep duration as well as sleep difficulties among 226,208 adults in the U...

Hepatitis B and Hepatitis C have been major disease-causing agents among humans since they were discovered in the 1960s. Both cause jaundice-like symptoms initially but their prognosis and treatment are somehow different and depend upon many demographic details, such as the age and susceptibility of the patients and any other comorbid conditions. They clinically present primarily with hepatitis and can have many adverse effects or even be life-threatening at times, if not treated properly. However, their epidemiological background and findings in terms of morbidity, mortality, and case fatality rates are different...

Background: Epidemiology studies have indicated an association of apolipoprotein E (ApoE) genetic polymorphism and circulating steroid hormone levels with the risk of Alzheimer's disease. The established physiologic relationship between apolipoproteins and steroid hormone indicate an important role of ApoE polymorphism in impacting the relationship between serum steroid hormones and cognition in the elderly. Study design: A total of 500 Chinese adults aged between 50 and 75 participated in this community-based cross-sectional study...
