Does pet ownership in infancy lead to asthma or allergy at school age? Pooled analysis of individual participant data from 11 European birth cohorts

Objective To examine the associations between pet keeping in early childhood and asthma and allergies in children aged 6–10 years. Design Pooled analysis of individual participant data of 11 prospective European birth cohorts that recruited a total of over 22,000 children in the 1990s. Exposure definition Ownership of only cats, dogs, birds, rodents, or cats/dogs combined during the first 2 years of life. Outcome definition Current asthma (primary outcome), allergic asthma, allergic rhinitis and allergic sensitization during 6–10 years of age. Data synthesis Three-step approach: (i) Common definition of outcome and exposure variables across cohorts; (ii) calculation of adjusted effect estimates for each cohort; (iii) pooling of effect estimates by using random effects meta-analysis models. Results We found no association between furry and feathered pet keeping early in life and asthma in school age. For example, the odds ratio for asthma comparing cat ownership with “no pets” (10 studies, 11489 participants) was 1.00 (95% confidence interval 0.78 to 1.28) (I2 = 9%; p = 0.36). The odds ratio for asthma comparing dog ownership with “no pets” (9 studies, 11433 participants) was 0.77 (0.58 to 1.03) (I2 = 0%, p = 0.89). Owning both cat(s) and dog(s) compared to “no pets” resulted in an odds ratio of 1.04 (0.59 to 1.84) (I2 = 33%, p = 0.18). Similarly, for allergic asthma and for allergic rhinitis we did not find associations regarding any type of pet ownership early in life. However, we found some evidence for an association between ownership of furry pets during the first 2 years of life and reduced likelihood of becoming sensitized to aero-allergens. Conclusions Pet ownership in early life did not appear to either increase or reduce the risk of asthma or allergic rhinitis symptoms in children aged 6–10. Advice from health care practitioners to avoid or to specifically acquire pets for primary prevention of asthma or allergic rhinitis in children should not be given.

Lead discovery, chemistry optimization, and biological evaluation studies of novel biamide derivatives as CB2 receptor inverse agonists and osteoclast inhibitors

N,N'-((4-(Dimethylamino)phenyl)methylene)bis(2-phenylacetamide) was discovered by using 3D pharmacophore database searches and was biologically confirmed as a new class of CB(2) inverse agonists. Subsequently, 52 derivatives were designed and synthesized through lead chemistry optimization by modifying the rings A-C and the core structure in further SAR studies. Five compounds were developed and also confirmed as CB(2) inverse agonists with the highest CB(2) binding affinity (CB(2)K(i) of 22-85 nM, EC(50) of 4-28 nM) and best selectivity (CB(1)/CB(2) of 235- to 909-fold). Furthermore, osteoclastogenesis bioassay indicated that PAM compounds showed great inhibition of osteoclast formation. Especially, compound 26 showed 72% inhibition activity even at the low concentration of 0.1 μM. The cytotoxicity assay suggested that the inhibition of PAM compounds on osteoclastogenesis did not result from its cytotoxicity. Therefore, these PAM derivatives could be used as potential leads for the development of a new type of antiosteoporosis agent.

Behavioral Economics and Physician Behavior

This study seeks to answer whether the availability heuristic leads physicians to utilize more medical care than is economically efficient. Do rare, salient events alter physicians' perceptions about the probability of patient harm? Do these events lead physicians to overutilize certain medical procedures? This study uses Pennsylvania inpatient hospital admissions data from 2009 aggregated at the physician level to investigate these questions. The data come from the 2009 Pennsylvania Health Care Cost Containment Council (PHC4). The study is divided into two parts. In Part I, we examine whether bad outcomes during childbirth (defined as maternal mortality, an obstetric fistula or a uterine rupture) lead physicians to utilize more cesarean sections on future patients. In Part II, we examine whether bad outcomes associated with appendicitis (defined as patient death, a perforated or ruptured appendix or sepsis) lead physicians to perform more negative appendectomies (appendectomies performed when the patient did not have appendicitis) on future patients. Overall the study does not find evidence to support the claim that the availability heuristic leads physicians to overutilize medical care on future patients. However, the study does find evidence that variations in health care utilization are strongly correlated with individual physician practice patterns. The results of the study also imply that physicians' financial incentives may be a source of variation in health care utilization.

"She Was Not Even Normal": Unreliable Narratives of Female Insanity in Jane Eyre, Rebecca, and Wide Sargasso Sea

In my thesis, I interrogate narrative reliability related to depictions of female insanity in Jane Eyre, Rebecca, and Wide Sargasso Sea. By subjecting the trustworthiness of her storytelling to criticism, especially as regards the concealed madwoman, Bertha Mason, Jane's narration is revealed as unstable, offering problematic insight into a character long considered unflinchingly honest. In du Maurier's later literary adaptation of Jane Eyre, Bertha's parallel character, the eponymous Rebecca, comes to the fore, while the novel's unnamed narrator remains in the shadows, and bases much of her storytelling upon hearsay, rather than the "autobiography" of Jane Eyre. The most transparent narrative voice, however, is Antoinette, the main character of Wide Sargasso Sea, the 1966 prequel to Jane Eyre. Despite her madness, Antoinette's narration makes no attempt at dissemblance, speaking forthrightly about her marriage and experience, proving a truthful narrator and openly rejecting the marginal status the earlier narrators try desperately to hide.

Sexing the Male: Manifestations of Masculinity in Jane Eyre, Wuthering Heights, and Villette

Abstract: This project considers Emily and Charlotte Brontë's constructions of masculinity in Jane Eyre, Wuthering Heights, and Villette. There is a vast proliferation of scholarship focusing on gender in the Victorian Era, but as much of this criticism focuses on women, the analysis of heterosexual masculinity in these novels provides a unique perspective on the complexities involved in gender constructions during this period. Masculine identity was in a transitory state in the early nineteenth century, as Romantic values were replaced by Victorian conceptions of masculinity, largely influencing the expectations of men. This paper argues that based on an understanding of femininity and masculinity as defined in relation to each other, the Brontë heroes look to the female characters as a source of stability to define themselves against, constructing a stagnant feminine role to frame an understanding of how masculinity was changing. The female characters resist this categorization, however, never allowing the men to fully classify them into stable feminine roles, which leads both shifting gender roles to intertwine and collapse in the novels, undermining any conceptualization of a stable or universal understanding of gender. The paper considers the role of masculinity based in class, relationships with women, and the understanding of sexual passion, to argue that the Brontës' portrayal of men emulates the anxieties surrounding the shift from Romantic to Victorian values of manliness, ultimately rejecting any stable definition of the nineteenth-century man.

Observation of Associated Near-Side and Away-Side Long-Range Correlations in √sNN=5.02 TeV Proton-Lead Collisions with the ATLAS Detector

Two-particle correlations in relative azimuthal angle (Delta phi) and pseudorapidity (Delta eta) are measured in root S-NN = 5.02 TeV p + Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1 mu b(-1) of data as a function of transverse momentum (p(T)) and the transverse energy (Sigma E-T(Pb)) summed over 3.1 < eta < 4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2 < vertical bar Delta eta vertical bar < 5) "near-side" (Delta phi similar to 0) correlation that grows rapidly with increasing Sigma E-T(Pb). A long-range "away-side" (Delta phi similar to pi) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small Sigma E-T(Pb), is found to match the near-side correlation in magnitude, shape (in Delta eta and Delta phi) and Sigma E-T(Pb) dependence. The resultant Delta phi correlation is approximately symmetric about pi/2, and is consistent with a dominant cos2 Delta phi modulation for all Sigma E-T(Pb) ranges and particle p(T).
