Toll-like receptors (TLRs), a family of pattern recognition receptors expressed on many cell types of innate immunity, recognize the pathogen-associated molecular patterns of microbes. The hygiene hypothesis suggests that a reduced microbial exposure in early childhood increases the susceptibility to allergic diseases due to deviation in development of the immune system. TLRs are key roles in the right and healthy direction of adaptive immunity with the induction of T-helper 2 toward Th1 immune responses and regulatory T cells...

INTRODUCTION: The purpose of this study was to compare the oral health status and its effect on the oral health-related quality of life (OHRQoL) of hospitalized and nonhospitalized elderly patients in a single community. The null hypothesis for the study states that there is no difference in the oral health status and OHRQoL between hospitalized and nonhospitalized elderly patients. MATERIALS AND METHODS: This study was conducted at the King Khalid Hospital and College of Dentistry, King Saud University, Riyadh, Kingdom of Saudi Arabia...

BACKGROUND: Over the next 20 years, oropharyngeal cancers (OPC) will represent the majority of head and neck cancers (HNCs) in the United States. It is estimated that human papillomavirus (HPV) may account for as much as 70% to 80% of OPCs in North America and in certain parts of Europe. It is hence crucial to understand the disease risk factors and natural history of oral HPV infections. We hypothesized that poor oral health (by measures such as poor oral hygiene and periodontal disease) leads to a higher degree of oral HPV-16 infections within a patient cohort from a dental school clinic...

Reduced microbial exposure in early childhood is postulated to be associated with subsequent immune deficiencies and associated health conditions. This corollary to the "hygiene hypothesis" has grown of popularity in the medical field, but can only be really tested with animal models. Based on previous observation that access to outdoor environment improves piglets' growth performance, we simulated early microbial exposure by providing pigs with topsoil during the lactation phase. Specifically, pigs from 20 litters were assigned to either control treatments (C) or soil treatments (S): pigs exposed to topsoil from day 4 postpartum to the end of lactation...

  Pharmacy education comprises basic pharmacy (organic chemistry, biochemistry, and physical chemistry) and applied pharmacy (clinical pharmacy, pharm aceutics, and chemical hygiene). Students are expected to apply these subjects studied in pharmacy school during their practical pharmacy training. However, knowledge gained in university does not appear to be fully utilized in practice. We hypothesized that this is due to a lack of connection between pre-practical training education and actual practical training...

BACKGROUND: The purpose of this retrospective medical record review was to report on recidivism to the ICU among adult postoperative cardiac and thoracic patients managed with a respiratory therapy assess-and-treat (RTAT) protocol. Our primary null hypothesis was that there would be no difference in all-cause unexpected readmissions and escalations between the RTAT group and the physician-ordered respiratory care group. Our secondary null hypothesis was that there would be no difference in primary respiratory-related readmissions, ICU length of stay, or hospital length of stay...

The hygiene hypothesis began as an attempt to explain the relatively rapid rise in atopic diseases. Strachan's early hypothesis regarding the role of family size and exposure to early childhood infections in the development of atopic diseases has clearly evolved to integrate the possible effects of hygiene, eradication of parasitic infections, immunizations, improvements in home heating and ventilation, dust mite exposure, breastfeeding duration, diet, parental smoking, pollution, and exposure to pets and farm animals...

The antigenic reactivity of constituents of Schistosoma mansoni and peanut (Arachis hypogaea) was investigated to determine whether identical antigenic epitopes possessed by both organisms provided a possible explanation for the negative correlation between chronic schistosome infection and atopy to allergens. Aqueous extracts of peanuts were probed in Western immunoblots with rabbit IgG antibodies raised against the egg, cercarial and adult worm stages of S. mansoni. Several molecules in the peanut extract were antigenically reactive with antibodies from the various rabbit anti-schistosome sera...

OBJECTIVES: Grooming has important utilitarian and social functions in primates but little is known about grooming and its functional analogues in traditional human societies. We compare human grooming to typical primate patterns to test its hygienic and social functions. MATERIALS AND METHODS: Bayesian phylogenetic analyses were used to derive expected human grooming time given the potential associations between grooming, group size, body size, terrestriality, and several climatic variables across 69 primate species...

The "hygiene hypothesis" postulates that reduced exposure to infections favours the development of autoimmunity and childhood type 1 diabetes (T1D). But on the other side, viruses, notably enteroviruses, are suspected to trigger T1D. The assessment of the possible relationships between infections and T1D still defies the classical tools of epidemiology. We report the methods and results of a geographical approach that maps the addresses of patients to a communicable diseases surveillance database. We mapped the addresses of patients at birth, infancy and T1D diagnosis to the weekly estimates of the regional incidences of 5 frequent communicable diseases routinely collected since 1984 by the French Sentinel network...

Necrotising enterocolitis (NEC) is the most commonly acquired gastrointestinal disease of neonates, particularly the very preterm (gestation <32 weeks) and/or very low birth weight (<1500g). It is associated with high morbidity and mortality. Despite improvement in neonatal care and increased use of expressed breast milk (EBM), the incidence remains high in many neonatal intensive care units (NICU), and even shows increasing trend in some countries. Numerous studies have pointed to the infective nature of NEC...

During the last years, the importance of a well equilibrated intestinal microbiota (eubiosis) has become more and more obvious in human health. Dysbiosis is now a well-recognized feature associated with IBD (inflammatory bowel disease). Rupture of the normal microbiota can occur through different mechanisms: (1) by a typical Western diet rich in fat and low in fiber, (2) by an acute disruption of the microbiota (by an acute gastroenteritis or by intake of antibiotics) or (3) by a combination of event in early childhood avoiding the establishment of eubiosis (the hygiene hypothesis)...

Hydatid disease (echinococcosis) is a chronic, endemic helminthic disease caused by the larval stage of the tapeworm, Echinococcus granulosus. This disease is endemic in many parts of the world, such as the Mediterranean area, and in particular in Algeria. Helminth parasites have developed complex strategies to modulate the immune responses of their hosts through versatile immune-regulatory mechanisms. These mechanisms may regulate immune responses associated with inflammatory diseases such as inflammatory bowel diseases (IBD)...

BACKGROUND: Water, sanitation and hygiene (WASH) interventions represent an important component of soil-transmitted helminth (STH) infection control, alongside the administration of anthelmintic drugs, which are generally targeted to school-aged children. Recent modelling studies have suggested that STH control programmes should be broadened to include all age groups across the community. We describe the protocol for a pilot study investigating the impact of school-versus-community-based delivery of integrated WASH and deworming programmes on STH infections in school-aged children in Timor-Leste...

BACKGROUND: The causes of acute malnutrition are complex and time and geography variant and need to be better understood in order to both design more effective nutrition programs and evaluate them. The findings reported here are part of an evaluation of a 4-year multisectoral nutrition program led by Concern Worldwide in the Sila Region of eastern Chad. OBJECTIVE: To present evidence and learning about the relationships between acute malnutrition and potential drivers in Sila, Chad...

BACKGROUND: Childhood food allergy and asthma rates are increasing. The hygiene hypothesis has been proposed as an explanation for the increased incidence of allergic disease. OBJECTIVE: To describe the association of childhood food allergy and asthma with hygiene factors, such as the number of siblings, antibiotic use, infection history, pet exposure, child care exposure, and maternalchild factors. METHODS: Children ages 021 years old (N = 1359) were recruited for a cross-sectional family-based study, including children with food allergy and children without food allergy, and their siblings...

Worldwide, there is little overlap between the prevalence of soil-transmitted helminths and type 2 diabetes (T2D). Helminth-induced type 2 immune responses and immune regulatory network might modulate the obesity-induced activation of inflammatory pathways that are associated with the development of insulin resistance, a strong predictor of the development of T2D. However, other factors such as helminth-associated changes in adiposity and gut microbiome might also contribute to improved metabolic outcomes. In this review we summarize epidemiological evidence for the link between helminths and T2D and discuss the potential mechanisms, based on findings from experimental studies as well as the limited number of studies in humans...

BACKGROUND: Actual caries figures emphasize the need to identify the risk indicators involved in the disease's development. The hypothesis that certain risk indicators might affect the dynamic evolution of the caries process was assessed; to clarify this premise, a cross-sectional survey was performed in school children. METHODS: A total of 390 subjects aged 6-8 years old were randomly selected. Caries was assessed, and the subjects were stratified as follows: i) highest caries score; ii) most prevalent caries score; and iii) number of affected teeth...

Epilepsy is one of the most widespread serious neurological disorders, and an aetiological explanation has not been fully identified. In recent decades, a growing body of evidence has highlighted the influential role of autoimmune mechanisms in the progression of epilepsy. The hygiene hypothesis draws people's attention to the association between gut microbes and the onset of multiple immune disorders. It is also believed that, in addition to influencing digestive system function, symbiotic microbiota can bidirectionally and reversibly impact the programming of extraintestinal pathogenic immune responses during autoimmunity...
