2Association of Helicobacter pylori infection and giardiasis: Results from a study of surrogate markers for fecal exposure among children显示文摘AIM: To investigate whether Helicobacter pylori (H pykori)infection is associated with hepatitis A virus (HAV) infection, presence of enteroparasites, and other surrogates of fecal exposure.METHODS: We conducted a cross-sectional study in 121 children consecutively admitted at a pediatric hospital inSalvador, Brazil.H pylori and HAV infection were identified by the presence of serum antibodies. Stool specimens were examined for the presence of ova and parasites. A structured questionnaire inquiring about sanitary conditions and life style was applied to each subject. RESULTS: Fifty-one of the 121 children (42.1%) werefound to be seropositive for H pylori, and 45 (37.2%) for HAV. The seroprevalence ofHpyloriand HAV both increased significantly with age. Cross-tabulation of data showed that 26 (21.5%) were seropositive and 51 (42.1%) were negative for bothHpyloriand HAV antibodies (χ2 = 7.18,OR = 2.8, CI 1.30-5.97). The age adjusted OR for an HAV-infected child being H pylori positive was 2.3 (CI1.02-5.03). The agreement between H pylori and HAVseropositivity was fair (κ = 0.24). After controlling for possible confounding, the variables remaining independently associated with seropositivity to H pyloriwere age,presence of Giardia lamblia in feces (OR = 3.2, 95%CI, 1.1-9.5) and poor garbage disposal quality (OR = 2.4,95%CI, 1.1-5.1).CONCLUSION: Our data suggest that H pylori infection is associated with surrogate markers of fecal exposure. Thus, we conclude that the fecal-oral route is relevant in the transmission of HP among children in an urban setting of a developing country. The association observed between G. lamblia and H pylori infection may have several explanations. Further studies to investigate this relationship are warranted.Edson Duarte Moreira Jr Victor Bastos Nassri Rafaela Sousa Santos Junísia Ferraz Matos Wilson Andrade de Carvalho Célia Stolve Silvani Círia Santana e Sant'Ana 2005World Journal of Gastroenterology2005,11,18:3
33D additive manufactured composite scaffolds with antibiotic-loaded lamellar fillers for bone infection prevention and tissue regeneration显示文摘Bone infections following open bone fracture or implant surgery remain a challenge in the orthopedics field.In order to avoid high doses of systemic drug administration,optimized local antibiotic release from scaffolds is required.3D additive manufactured(AM)scaffolds made with biodegradable polymers are ideal to support bone healing in non-union scenarios and can be given antimicrobial properties by the incorporation of antibiotics.In this study,ciprofloxacin and gentamicin intercalated in the interlamellar spaces of magnesium aluminum layered double hydroxides(MgAl)andα-zirconium phosphates(ZrP),respectively,are dispersed within a thermoplastic polymer by melt compounding and subsequently processed via high temperature melt extrusion AM(~190◦C)into 3D scaffolds.The inorganic fillers enable a sustained antibiotics release through the polymer matrix,controlled by antibiotics counterions exchange or pH conditions.Importantly,both antibiotics retain their functionality after the manufacturing process at high temperatures,as verified by their activity against both Gram+and Gram-bacterial strains.Moreover,scaffolds loaded with filler-antibiotic do not impair human mesenchymal stromal cells osteogenic differentiation,allowing matrix mineralization and the expression of relevant osteogenic markers.Overall,these results suggest the possibility of fabricating dual functionality 3D scaffolds via high temperature melt extrusion for bone regeneration and infection prevention.María C´amara-Torres Stacy Duarte Ravi Sinha Ainhoa Egizabal Noelia´Alvarez Maria Bastianini Michele Sisani Paolo Scopece Marco Scatto Alessandro Bonetto Antonio Marcomini Alberto Sanchez Alessandro Patelli Carlos Mota Lorenzo Moroni 2021Bioactive Materials2021,6,4:2
