    Notes: Background Environmental factors acting early in life are key determinants of the incidence of allergic disease. Whether breastfeeding is protective against allergic disorders remains controversial.Objective The present cross-sectional study examined the relationship between feeding patterns in the first 3 months of life and the prevalence of symptoms of wheeze, atopic eczema, and rhinoconjunctivitis during the past 12 months in Japanese adolescents.Methods The subjects were 5614 of 9008 students (62%) aged 12–15 years from all public junior high schools in Suita, Japan in 2001. This study used the diagnostic criteria of the International Study of Asthma and Allergies in Childhood. Adjustment was made for gender, grade, number of older siblings, and parental history of allergy.Results Feeding pattern was unrelated to the prevalence of wheeze or rhinoconjunctivitis. The prevalence of atopic eczema was significantly higher in children who had been breastfed than in artificial milk feeders (adjusted odds ratios = 1.40 and 1.56, 95% confidence intervals: 1.01–1.98 and 1.13–2.22 for mixed milk intake and breastfeeding only vs. artificial milk consumption, respectively; P = 0.01 for linear trend). When children were divided according to a positive or negative allergic history in at least one parent, an increased prevalence of atopic eczema associated with breastfeeding was found in children with a negative parental allergic history compared with those with a positive parental allergic history.Conclusion The findings suggest that breastfeeding may be associated with an increased prevalence of atopic eczema, especially among children without a parental history of allergy.

    Notes: Abstract  Background: Stenotrophomonas maltophilia is an opportunistic, gram-negative bacillus. Endophthalmitis induced by S. maltophilia has been described in only two cases after intraocular lens implantation. We report S. maltophilia endophthalmitis in two patients with diabetes mellitus after intraocular lens implantation and compare the characteristics of the S. maltophilia-induced endophthalmitis with two previous cases.Methods: A 68-year-old woman and a 74-year-old man with diabetes mellitus developed S. maltophilia endophthalmitis within 5 days of intraocular lens implantation. We performed intraocular lens removal and vitrectomy, which resolved the inflammation. No recurrences were found.Results: Cultures grew S. maltophilia in both cases, and one of the organisms was multiresistant. The final visual acuity was counting fingers and 0.3. The first case revealed a tractional retinal detachment during vitrectomy.  Conclusions: S. maltophilia is a potential opportunistic intraocular pathogen, and the incidence of multiresistant S. maltophilia is increasing. S. maltophilia causes acute endophthalmitis, and its prognosis may not be poor unless the eye has a history of serious disease before the cataract surgery. The combined procedure of intraocular lens removal and vitrectomy was useful in resolving the inflammation and preventing recurrences.

    Description: During cell entry, capsids of incoming influenza A viruses (IAVs) must be uncoated before viral ribonucleoproteins (vRNPs) can enter the nucleus for replication. After hemagglutinin-mediated membrane fusion in late endocytic vacuoles, the vRNPs and the matrix proteins dissociate from each other and disperse within the cytosol. Here, we found that for capsid disassembly, IAV takes advantage of the host cell's aggresome formation and disassembly machinery. The capsids mimicked misfolded protein aggregates by carrying unanchored ubiquitin chains that activated a histone deacetylase 6 (HDAC6)-dependent pathway. The ubiquitin-binding domain was essential for recruitment of HDAC6 to viral fusion sites and for efficient uncoating and infection. That other components of the aggresome processing machinery, including dynein, dynactin, and myosin II, were also required suggested that physical forces generated by microtubule- and actin-associated motors are essential for IAV entry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Banerjee, Indranil -- Miyake, Yasuyuki -- Nobs, Samuel Philip -- Schneider, Christoph -- Horvath, Peter -- Kopf, Manfred -- Matthias, Patrick -- Helenius, Ari -- Yamauchi, Yohei -- New York, N.Y. -- Science. 2014 Oct 24;346(6208):473-7. doi: 10.1126/science.1257037.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Biochemistry, Eidgenossische Technische Hochschule (ETH) Zurich, Switzerland. ; Epigenetics, Friedrich Miescher Institute for Biomedical Research, Basel, Switzerland. ; Institute of Molecular Health Sciences, ETH Zurich, Switzerland. ; Synthetic and Systems Biology Unit, Biological Research Center, Szeged, Hungary. ; Epigenetics, Friedrich Miescher Institute for Biomedical Research, Basel, Switzerland.
