Background Despite evidence supporting the safety of breast implants, some women associate their implants with adverse health effects and have called this syndrome "breast implant illness." We sought to characterize breast implant illness symptoms and to report how implant removal affects their symptoms. Methods An anonymous 20 question survey was administered to the Facebook group: "UTAH Breast Implant Illness" to characterize the symptoms these women attributed to their breast implants. Several questions allowed us to evaluate how implant removal affected women's symptoms. Results Of the 182 respondents, 97% report that implants negatively affect their health and 95% identify these symptoms with breast implant illness. Ninety-six percent of respondents had implants placed for cosmetic reasons and 51% had silicone implants. The most common symptoms associated with breast implant illness are brain fog (95%), fatigue (92%), joint pain (80%), and hair loss (74%). Sixty percent of respondents learned about breast implant illness from family/friends and/or social media platforms (56%), 40% of respondents had their implants removed, and 97% report relief of their symptoms post-removal (23% complete, 74% partial). Following explantation, there was a significant improvement in all but one reported symptom. An association was found between the number of symptoms reported prior to explantation and the number of symptoms resolving following explantation. Conclusions Breast implant illness is a syndrome characterized by fatigue, decreased focus, hair loss, and joint pain after the placement of breast implants. Nearly all patients report improvement of symptoms after implant removal. Significant efforts should be made to better understand breast implant illness and its etiology.

Background: The present study performed a systematic review and meta-analysis of clinical trials using bisphosphonates for bone demineralization in human immunodeficiency virus (HIV) patients. Methods: A comprehensive literature search was performed from January 2004 to January 2020 considering the bone mineral density (BMD) of the lumbar spine (LS) as the main outcome. Out of 214 titles that met criteria, 9 studies fulfilled the selection criteria. Results: A total of 394 patients were identified, and they were allocated into 2 groups: the intervention group (200 patients), to whom a combination of alendronate or zoledronate with calcium and vitamin D was administered; and control group (194 patients), to whom only calcium and vitamin D was administered. Clinical profile and indicators of bone metabolism of the participants were evaluated regarding effect size, homogeneity, and consistency. No substantial heterogeneity between the groups was found for the baseline variables, and there was high consistency to the main outcome. The meta-analysis shows a significant difference in post-treatment BMD, favoring the intervention over the control treatment. The intervention improved LS density up to 0.227 g/cm², raising the average to the levels of general population. Adverse effects related to intervention were fever immediately after zoledronate administration and gastrointestinal complaints during alendronate usage. Other adverse effects were barely reported and poorly connected to intervention by studies’ authors, despite all of them have been successfully resolved. Conclusions: This study provides evidence that BMD post-treatment is better in HIV patients who used bisphosphonates combined with calcium and vitamin D.

In this work, the effect of the growth rate (VL) and cooling rate (TR), primary dendritic arm spacing (1) and Al2Cu intermetallic phase on the microhardness was investigated during transient horizontal directional solidification of Al-3wt%Cu and Al-8wt%Cu alloys. Microstructural characterization of the investigated alloys was performed using traditional techniques of metallography, optical and SEM microscopy and X-Ray diffraction. The microhardness evolution as a function of the thermal and microstructural parameters (VL, TR, and 1) was evaluated using power and Hall-Petch type experimental laws, which were compared with other laws in the literature. In order to examine the effect of the Al2Cu intermetallic phase, microhardness measurements were performed in interdendritic regions. Finally, a comparative analysis was performed between the experimental data of this work and theoretical models from the literature that have been proposed to predict primary dendrite arm spacing, which have been tested in numerous works considering upward directional solidification.

Nowadays, fuel consumption and exhaust emissions are topical issues in the automotive field, as environmental safeguard legislation constraints are going to get tougher. Indeed, one of the most efficient methods to contain fuel consumption and emissions is the weight reduction of the vehicle. In this paper, a feasibility study on the lightweight redesign of a metallic car hood by using composite materials is presented. In particular, two different configurations, employing composite laminates and sandwich structures, are investigated. The feasibility of each configuration is assessed in terms of stiffness specifications and pedestrian safety requirement. Hence, Head Injury Criteria are employed, according to regulations. Finally, an optimization procedure on the stacking sequence of the composite laminates is performed, to determine, among the feasible solutions, the one characterized by the minimum weight.
A “THIRD WAY” IN THE PHILIPPINES: VOLUNTARY ORGANIZING FOR A NEW DISASTER MANAGEMENT PARADIGM
RALPH S. BROWER,FRANCISCO A. MAGNO 한국행정학회 2011 International Review of Public Administration Vol.16 No.1
This study illuminates the role of civil society actors in advocating for and helping implement The Philippine Disaster Risk Reduction and Management Act of 2010. We illustrate how these actors served as both bottom-up and top-down brokers and translators in communicating ideas and action between vulnerable communities they represent and policy actors in the Philippine national government. We situate their actions within the Philippines’ unique historical, cultural, political, and socioeconomic context, noting the significance of their policy entrepreneurship by comparison to conditions a mere 25 years earlier, when the Marcos Regime would have hunted down and killed them for their activism. We conclude with observations about important contributions that the disaster risk reduction paradigm makes to development theory, and assert the importance of political and social goals, that are often drowned out by the dominant role that economics and ownership models hold in some Western conceptions of voluntary organizing.

Aluminum casting alloys have properties which are of great industrial interest, such as low density, good corrosion resistance,high thermal and electrical conductivities, good combination of mechanical properties, good workability in machiningprocesses and mechanical forming. Currently, these alloys are produced in various systems and dozens of compositions. Inthis investigation, a mutual interaction of thermal parameters, scale of the dendritic microstructure, intermetallic compounds(IMCs), microhardness and tensile properties/fracture characteristics of a casting Al–7wt%Si–3wt%Cu–0.3wt%Fe alloywas analyzed. Solidification experiments were developed using a furnace that promoted horizontal growth under transientheat flow conditions. Then, growth rate (VL), cooling rate (CR), and local solidification time (tSL) were determined frommeasured temperature profiles. Secondary dendritic spacings (λ2), Si particles, Fe-rich and Al2Cuintermetallic phases werecharacterized by optical and SEM microscopy, as well as the area mapping and point-wise EDS microanalysis. Hence, theinterrelations involving Vickers microhardness (HV), yield strength (σYS), ultimate tensile strength (σUTS) and elongation(E%) with microstructural features were evaluated by mathematical equations. IMCs as well as morphologies of Si were alsoanalyzed in the fracture regions. In addition, the experimental growth law of λ2 = f(tSL) proposed in this study was comparedwith a predictive theoretical model reported in the literature for multicomponent alloys. It was observed that areas that tendto grow faster (lowest λ2 values) were associated with the highest σUTS and E% values, while HV and σYS properties were notaffected by the thermal and microstructural parameters (CR and λ2). In addition, less extensive cleavage planes accompaniedby small dimples in were observed in fractured samples with lower λ2 values.

Paula Bianca P. Lapuz,FRANCISCO A. MAGNO 이화여자대학교 국제지역연구소 2019 Asian International Studies Review Vol.20 No.2
This article reviews the emergence of international norms connectedwith disability-inclusive elections and provides evidence of howthey were cascaded and internalized in the Philippines. It examinesthe experience of the persons with disabilities (PWD) sector in thecampaign for disability-inclusive elections. With the support ofcivil society organizations and international development partners,the PWD sector lobbied for the passage of the Accessible PollingPlace (APP) Act which aims to improve the enfranchisement ofPWDs. Primary data were collected through key informantinterviews and focus group discussions, while a contextualanalysis of relevant secondary documents was conducted to showproof of norm internalization in the establishment of disabilityinclusiveelections.

Objective: This systematic review aimed to evaluate periodontal parameters in orthodontically tractioned teeth compared with the respective non-tractioned contralateral teeth. Methods: Search strategies were developed for six electronic databases and gray literature. Random-effects meta-analyses were performed for the outcomes of interest. Furthermore, the certainty of the evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) tool. Results: Overall, 2,082 articles were identified, of which 24 were selected for the qualitative synthesis. A significant difference was observed between the impacted and contralateral teeth (mean difference [MD] = 0.25; 95% confidence interval [CI] = 0.10–0.40; I2 = 0%) when the gingival index was evaluated. Additionally, impacted teeth showed a greater probing depth, with a significant mean difference between the groups (MD = 0.14; 95% CI = 0.07–0.20; I2 = 6%). Most studies had a low risk of bias; however, the certainty of the evidence was very low owing to the design of existing studies. Conclusions: The evidence in the literature indicated that tractioned teeth might show worsening of periodontal parameters related to the gingival index and probing depth; however, the evidence remains uncertain about this outcome. Furthermore, probing depth should be considered regarding its clinical significance because of the small effect size observed.
