The progressive launch of these nanoparticles in the environment has been accompanied by concern in understanding the dynamics and the toxic effect of these xenobiotic in different ecosystems, either on their own or in tandem with different contaminants (such as organic compounds and heavy metals), possibly altering their toxicity. Nevertheless, it remains unknown if these combined effects may induce damage in freshwater organisms. Therefore, this study aimed to analyze the consequences caused by NpTiO2, after a waterborne exposure of 96 h to a Neotropical fish species Hoplias intermedius, as well as after a co-exposure with lead, whose effects for fish have already been well described in the literature. The characterization of NpTiO2 stock suspension was carried out in order to provide additional information and revealed a stable colloidal suspension. As a result, NpTiO2 showed some genotoxic effects which were observed by comet assay in gill, kidney and brain ce...
Conclusions: Results of the present study support the interpersonal theory of suicide, which suggests that self-reported thwarted belongingness can foster WD. Clinical implications: Clinicians should consider social dissatisfaction and withdrawal as risk factors for WD and design interventions that foster social skills or meaningful connections.

CONCLUSIONS: we found an association between SIBO and allergic disease, especially allergic rhinitis, cow's milk protein allergy and asthma. Thus, SIBO should be ruled out in pediatric patients with CAP and allergic disease. PMID: 31617366 [PubMed - as supplied by publisher]
CONCLUSIONS: this meta-analysis supported the association of AF with increased risk of GERD. PMID: 31617365 [PubMed - as supplied by publisher]
CONCLUSION: these data support the hypothesis that the hepatitis C virus may worsen quality of life in asymptomatic patients. PMID: 31617364 [PubMed - as supplied by publisher]
We report a case of a 67-year-old female presented with hematemesis eventually diagnosed with duodenal mucormycosis, while radiology characteristics suggested malignancy. PMID: 31617363 [PubMed - as supplied by publisher]
Authors: Taki S, Maekita T, Sakata M, Fukatsu K, Maeda Y, Iguchi M, Ito H, Kitano M Abstract Continuous duodenal levodopa/carbidopa intestinal gel delivery by a gastrostomy infusion system improves control of Parkinson's disease. The overall complication rates of percutaneous endoscopic gastrojejunostomy were reported to be 41% and 59% for immediate and delayed adverse events, respectively. A 72-year-old woman underwent percutaneous endoscopic gastrojejunostomy using the delivery system noted above. Abdominal pain and vomiting occurred 3 months later. Esophagogastroduodenoscopy showed a longitudinal ulcer extending...
Conclusions: Our study is the first to report that endoscopic therapy of PFCs using LAMS is safe and effective even in a community hospital setting with limited resources and support compared to large academic centers. PMID: 31615198 [PubMed - as supplied by publisher]
