Two-way Mirrors: Dancing in the Zoomosphere

Dan Graham's work with mirrors and installation from the 1970s provides an unexpected launchpad for understanding the structures underlying perception in Zoom interfaces. The article explores the intricacies of Graham's two-way mirrors as a means to articulate perceptual experiences of dancing in the Zoomosphere, with examples from teaching, choreographing and performing via Zoom during Covid 19 isolation conditions

Methods of Suicide by Women in Ireland 1980-2009

Irish female methods of suicide from 1980 till 2009 were investigated in order to determine the likelihood of the method of suicide as determined by decade as well as the age at death. Secondary data analysis was conducted on the National Suicide Research Foundation (NSRF) dataset. Multinomial logistic regression was used to compare methods of suicide using odds ratios. Log-linear analysis was conducted in order to investigate possible interactions between the variables. A stepwise backward elimination procedure determined the most parsimonious model to account for the observed frequencies. Follow-up chi-square analyses were conducted on the three-way interaction in order to separately assess possible interactions of decade and age on method of suicide. Findings showed that the odds of hanging increased over time in comparison to overdosing and drowning. Interaction effects are present between all three variables and there is a significant association between age and decade for hanging but not so for overdosing or drowning. It is concluded that hanging is a method which is indeed increasing over time for women in Ireland

Valproate Used in Women of Childbearing Age with Epilepsy

Valproate is one of the oldest known anti-epileptic drugs (AED) in practice which was discovered in 1881 and later in 1962 was approved for treating epilepsy. It is indicated in most of the seizure types including generalized onset (motor, non-motor and myoclonic), focal onset, unknown onset and unclassified. Valproate has other indications in migraine prophylaxis, and bipolar disorder

Tubal Ligation, Hysterectomy and Ovarian Cancer: A Meta-Analysis

Purpose: The purpose of this meta-analysis was to determine the strength of the association between gynecologic surgeries, tubal ligation and hysterectomy, and ovarian cancer. Methods: We searched the PubMed, Web of Science, and Embase databases for all English-language articles dated between 1969 through March 2011 using the keywords "ovarian cancer" and "tubal ligation" or "tubal sterilization" or "hysterectomy." We identified 30 studies on tubal ligation and 24 studies on hysterectomy that provided relative risks for ovarian cancer and a p-value or 95% confidence interval (CI) to include in the meta-analysis. Summary RRs and 95% CIs were calculated using a random-effects model. Results: The summary RR for women with vs. without tubal ligation was 0.70 (95%CI: 0.64, 0.75). Similarly, the summary RR for women with vs. without hysterectomy was 0.74 (95%CI: 0.65, 0.84). Simple hysterectomy and hysterectomy with unilateral oophorectomy were associated with a similar decrease in risk (summery RR = 0.62, 95%CI: 0.49-0.79 and 0.60, 95%CI: 0.47-0.78, respectively). In secondary analyses, the association between tubal ligation and ovarian cancer risk was stronger for endometrioid tumors (summary RR = 0.45, 95%CI: 0.33, 0.61) compared to serous tumors. Conclusion: Observational epidemiologic evidence strongly supports that tubal ligation and hysterectomy are associated with a decrease in the risk of ovarian cancer, by approximately 26-30%. Additional research is needed to determine whether the association between tubal ligation and hysterectomy on ovarian cancer risk differs by individual, surgical, and tumor characteristics

However, the scope of exercise biology extends well beyond energy expenditure and has emerged as a great ‘polypill’, which is safe, reliable and cost-effective not only in disease prevention but also treatment. Biological mechanisms by which exercise influences homeostasis are becoming clearer and involve multi-organ systemic adaptations. Most of the elements of a modern lifestyle influence the indigenous microbiota but few studies have explored the effect of increased physical activity. While dietary responses to exercise obscure the influence of exercise alone on gut microbiota, professional athletes operating at the extremes of performance provide informative data. We assessed the relationship between extreme levels of exercise, associated dietary habits and gut microbiota composition, and discuss potential mechanisms by which exercise may exert a direct or indirect influence on gut microbiota.The authors are supported in part by research grants from Science Foundation Ireland including a centre grant (Alimentary Pharmabiotic Centre; Grant Numbers SFI/12/RC/2273 and 12/RC/2273).

Targeting the Microbiota to Address Diet-Induced Obesity: A Time Dependent Challenge

peer-reviewedLinks between the gut microbiota and host metabolism have provided new perspectives on obesity. We previously showed that the link between the microbiota and fat deposition is age- and time-dependent subject to microbial adaptation to diet over time. We also demonstrated reduced weight gain in diet-induced obese (DIO) mice through manipulation of the gut microbiota with vancomycin or with the bacteriocin-producing probiotic Lactobacillus salivarius UCC118 (Bac+), with metabolic improvement achieved in DIO mice in receipt of vancomycin. However, two phases of weight gain were observed with effects most marked early in the intervention phase. Here, we compare the gut microbial populations at the early relative to the late stages of intervention using a high throughput sequencing-based analysis to understand the temporal relationship between the gut microbiota and obesity. This reveals several differences in microbiota composition over the intervening period. Vancomycin dramatically altered the gut microbiota composition, relative to controls, at the early stages of intervention after which time some recovery was evident. It was also revealed that Bac+ treatment initially resulted in the presence of significantly higher proportions of Peptococcaceae and significantly lower proportions of Rikenellaceae and Porphyromonadaceae relative to the gut microbiota of L. salivarius UCC118 bacteriocin negative (Bac-) administered controls. These differences were no longer evident at the later time. The results highlight the resilience of the gut microbiota and suggest that interventions may need to be monitored and continually adjusted to ensure sustained modification of the gut microbiota.The authors are supported in part by Teagasc, Science Foundation Ireland (in the form of a research centre grant to the Alimentary Pharmabiotic Centre and PI awards to PWOT and PC) and by Alimentary Health Ltd

Use of Prescription Medication by Individuals Who Died by Suicide in Northern Ireland

OBJECTIVES/: To understand medication use prior to suicide in relation to patterns, polypharmacy and adherence. METHODS: 1,371 suicide cases were coded and latent class analysis used to identify combinations of medications prescribed prior to death. RESULTS: Two thirds had been prescribed medication with 30.7% prescribed three or more. Latent class analysis revealed three classes: Mixed medication use, primarily mental medication use, and baseline/low medication use. There are potentially high rates of medication non-adherence. CONCLUSIONS: Both medication use but also non-adherence rates were high in this sample of individuals who died by suicide. Potential implications and areas for future research are discussed
