Percutaneous endoscopic gastrostomy (PEG) is used as an alternative to enteral/nasoenteral feeding in situations where long-term oral feeding is ineffective or not tolerated. It is mostly preferred in patients with neurological conditions and also to support nutrition in patients with congenital heart diseases, cystic fibrosis, inflammatory bowel disease, and various oropharyngeal diseases. Although it is easily applicable compared to many invasive procedures, it has complications ranging from wound infection to death...

Non-human primates (NHPs) for biomedical research are commonly infected with Shigella spp. that can cause acute dysentery or chronic episodic diarrhea. These animals are often prophylactically and clinically treated with quinolone antibiotics to eradicate these possible infections. However, chromosomally- and plasmid-mediated antibiotic resistance has become an emerging concern for species in the family Enterobacteriaceae . In this study, five individual isolates of multi-drug resistant Shigella flexneri were isolated from the feces of three macaques...

Impaired epithelial barrier function disrupts immune homeostasis and increases inflammation in intestines, leading to many intestinal diseases. The blend of organic acids (OAs) and medium chain fatty acids (MCFAs) has been shown to have synergistic bactericidal effect. In this study, we demonstrated that two blends of OAs and MCFAs (OM1 and OM2) could prevent the inflammatory response and intestinal barrier dysfunction in enterohemorrhagic Escherichia coli (EHEC)-infected mice. Treatments of OM1 and OM2 significantly reduced the body weight loss and production of IL-6 and TNF-α induced by EHEC...

Uridine is a potential endogenous neuromodulator studied for several decades for its antiepileptic effect, but the results were controversial. One remarkable feature of uridine is its regulatory action on the dopaminergic pathways. In this study, the changes in uridine and dopamine (DA) release were examined in the mouse corpus striatum after pilocarpine (PC) intraperitoneal injection. Then, the effect of uridine pre-treatment on DA release and expression of dopamine receptor (DR) was determined. The results revealed an increased uridine release initially, followed by a downward trend after an injection of 400-mg/kg PC...

Upshaw-Schulman syndrome (USS) is caused by severe ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) deficiency due to homozygous or compound heterozygous mutations in the ADAMTS13 gene. Previous studies suggest three possible disease mechanisms: (1) reduced secretion of ADAMTS13 variants, (2) impaired proteolytic activity, (3) defective biosynthesis due to nonsense-mediated decay. Expression studies have failed to establish a clear genotype/phenotype correlation that could explain the significant variability in the age of onset and patients' clinical courses...

Aluminum salt (Alum) is one of the most important immune adjuvants approved for use in humans, however it is not suitable for vaccination against various chronic infectious diseases and cancers for not being able to induce cell-mediated (Th1) immunity. Here, we encapsulated an Alum colloid inside β-glucan particles (GPs), which are a type of natural particles derived from the yeast glucan shells, to prepare hybrid GP-Alum (GP-Al) adjuvant particles with a very uniform size of 2-4 μm. These hybrid particles can be used to load antigen proteins through a simple mixing procedure, and can be highly specifically targeted to antigen-presenting cells (APCs) and strongly activate dendritic cells (DCs) maturation and cytokine secretion...

A study was conducted to evaluate the effects of feeding salinomycin at the recommended prophylactic level, and at 2 and 3 times this level, to finishing male broilers (d 21 to 38). Four treatment groups were given the experimental diets containing 0, 60, 120, or 180 parts per million (ppm) salinomycin from d 21 to 38. Performance, relative organ weights, selected serum enzymes, and salinomycin residues in liver, muscle, and serum were determined. Salinomycin supplementation had no effect on body weight, feed intake, or feed conversion, and caused no overt signs of toxicity...

Because of the epidemic of myopia with both its short-term and long-term effects, we desperately need ways to slow myopic progression. In this study which was part of a myopia prevention symposium, the author answers the following question: Assuming that researchers did come up with a pharmacological treatment to slow myopic progression-what would it take to obtain regulatory approval from the United States Food and Drug Administration (FDA)? Previous publicly available information (a 2003 FDA advisory committee on this topic, International Conference on Harmonisation guidances on drug development, and published articles) as well as the author's experience is used...

BACKGROUND: Development of endophthalmitis during cataract surgery is one of the most severe complications and it may also result in blindness and globe loss. AIMS: To evaluate the effect of an ophthalmic cefuroxime solution (Aprokam® ) that is prophylactically used in phacoemulsification surgery performed due to cataract that eventually occurs in patients with or without penetrating keratoplasty. STUDY DESIGN: Case-control study. METHODS: In this retrospective study, patients who had undergone penetrating keratoplasty and for whom phacoemulsification surgery was performed due to cataract and an intracameral ophthalmic cefuroxime solution (Aprokam® ) was administered for prophylaxis were evaluated in comparison with patients with cataract without keratoplasty...

The meniscus plays a vital role in knee biomechanics, and its physical absence or functional incompetence (e.g., irreparable root or radial tear) leads to unacceptably high rates of joint degeneration in affected populations. Meniscal allograft transplantation has been used successfully to treat patients with postmeniscectomy syndrome, and there is early laboratory and radiographic evidence hinting at a potential prophylactic role in preventing joint degeneration. We present a technique for lateral meniscal allograft transplantation using the CONMED Meniscal Allograft Transplantation system...

BACKGROUND AND AIMS: Absence or low anti-hepatitis B (HBV) surface antibody (anti-HBs) is associated with increased risk of HBV reactivation in lymphoma patients with resolved HBV infection receiving rituximab-containing chemotherapy. Quantification of anti-HBV core antibody (anti-HBc) is a new marker associated with the natural history and treatment response of chronic HBV infection. This study investigated whether baseline anti-HBc and anti-HBs levels may better predict HBV reactivation...

Emerging and re-emerging viral infections transmitted by insect vectors (arthopode-borne viruses, arbovirus) are a serious threat to global public health. Among them, yellow fever (YFV), dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses are particularly important in tropical and subtropical regions. Although vector control is one of the most used prophylactic measures against arboviruses, it often faces obstacles, such as vector diversity, uncontrolled urbanization and increasing resistance to insecticides...
