Asymmetric preparation of antifungal 1-(4 -chlorophenyl)-1-cyclopropyl methanol and 1-(4 -chlorophenyl)-2-phenylethanol. Study of the detoxification mechanism by Botrytis cinerea
Chiral alcohols are important as bioactive compounds or as precursors to such molecules. On the basis of
the different antifungal properties of the enantiopure alcohol derivatives of 4-chlorophenyl cyclopropyl
ketone and benzyl 4-chlorophenyl ketone, their enantioselective synthesis by chemical and biocatalytic
methods was studied. The detoxification pathways by the phytopathogen fungus Botrytis cinerea are
reported
Supplement: "Localization and broadband follow-up of the gravitational-wave transient GW150914" (2016, ApJL, 826, L13)
This Supplement provides supporting material for Abbott et al. (2016a). We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the current EM follow-up program. We compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow-up observations that were performed in the different bands
Time to Switch to Second-line Antiretroviral Therapy in Children With Human Immunodeficiency Virus in Europe and Thailand.
Background: Data on durability of first-line antiretroviral therapy (ART) in children with human immunodeficiency virus (HIV) are limited. We assessed time to switch to second-line therapy in 16 European countries and Thailand. Methods: Children aged <18 years initiating combination ART (â„2 nucleoside reverse transcriptase inhibitors [NRTIs] plus nonnucleoside reverse transcriptase inhibitor [NNRTI] or boosted protease inhibitor [PI]) were included. Switch to second-line was defined as (i) change across drug class (PI to NNRTI or vice versa) or within PI class plus change of â„1 NRTI; (ii) change from single to dual PI; or (iii) addition of a new drug class. Cumulative incidence of switch was calculated with death and loss to follow-up as competing risks. Results: Of 3668 children included, median age at ART initiation was 6.1 (interquartile range (IQR), 1.7-10.5) years. Initial regimens were 32% PI based, 34% nevirapine (NVP) based, and 33% efavirenz based. Median duration of follow-up was 5.4 (IQR, 2.9-8.3) years. Cumulative incidence of switch at 5 years was 21% (95% confidence interval, 20%-23%), with significant regional variations. Median time to switch was 30 (IQR, 16-58) months; two-thirds of switches were related to treatment failure. In multivariable analysis, older age, severe immunosuppression and higher viral load (VL) at ART start, and NVP-based initial regimens were associated with increased risk of switch. Conclusions: One in 5 children switched to a second-line regimen by 5 years of ART, with two-thirds failure related. Advanced HIV, older age, and NVP-based regimens were associated with increased risk of switch

Clinical characteristics, one-year change in ejection fraction and long-term outcomes in patients with heart failure with mid-range ejection fraction: a multicentre prospective observational study in Catalonia (Spain)
OBJECTIVES: The aim of this study was to analyse baseline characteristics and outcome of patients with heart failure and mid-range left ventricular ejection fraction (HFmrEF, left ventricular ejection fraction (LVEF) 40%-49%) and the effect of 1-year change in LVEF in this group. SETTING: Multicentre prospective observational study of ambulatory patients with HF followed up at four university hospitals with dedicated HF units. PARTICIPANTS: Fourteen per cent (n=504) of the 3580 patients included had HFmrEF. INTERVENTIONS: Baseline characteristics, 1-year LVEF and outcomes were collected. All-cause death, HF hospitalisation and the composite end-point were the primary outcomes. RESULTS: Median follow-up was 3.66 (1.69-6.04) years. All-cause death, HF hospitalisation and the composite end-point were 47%, 35% and 59%, respectively. Outcomes were worse in HF with preserved ejection fraction (HFpEF) (LVEF>50%), without differences between HF with reduced ejection fraction (HFrEF) (LVEF50%. While change in LVEF as continuous variable was not associated with better outcomes, those patients who evolved from HFmrEF to HFpEF did have a better outcome. Those who remained in the HFmrEF and HFrEF groups had higher all-cause mortality after adjustment for age, sex and baseline LVEF (HR 1.96 (95% CI 1.08 to 3.54, P=0.027)âand HR 2.01 (95% CI 1.04 to 3.86, P=0.037), respectively). CONCLUSIONS: Patients with HFmrEF have a clinical profile in-between HFpEF and HFrEF, without differences in all-cause mortality and the composite end-point between the three groups. At 1âyear, patients with HFmrEF exhibited the greatest variability in LVEF and this change was associated with survival
Lo esencial no puede ser invisible a los ojos : pobreza e infancia en América Latina
El propĂłsito central de este libro es hacer Ă©nfasis en que el debate sobre la pobreza en AmĂ©rica Latina, en particular en la niñez y adolescencia, debe ser parte de las discusiones que se estĂĄn dando a nivel global con respecto a la justicia, la libertad, la ciudadanĂa, la identidad, la participaciĂłn, y la paz. Asimismo, busca dar impulso a los esfuerzos en nuestra regiĂłn por generar un pensamiento propio, que se fundamente en la capacidad de resistencia y de generaciĂłn de alternativas de la poblaciĂłn sin que se limite a las visiones y prĂĄcticas tradicionales de fomentar e implementar polĂticas sociales
Tackling Child Poverty in Latin America: Rights and Social Protection in Unequal Societies
This book highlights current debates about concepts, methods, and policies related to poverty in Latin America. It focuses on child and adolescent well-being and the issue of inclusive societies. Its goal is to promote new and critical thinking about these issues globally and in Latin America. The authors emphasize the need to develop new conceptual and practical avenues that can address the issues of poverty, marginalization, exclusion, and old and new inequalities in post-neoliberal times. The objective is to advance the rights of all children and adolescents in the region. This urgent book represents a unique opportunity for practitioners, policy makers, researchers, and students to get access to the most up-to-date perspectives on child poverty and inequality from a conceptual and practical point of view
La medicina y los seguros en el abordaje del problema de los invålidos del trabajo en España en la primera mitad del siglo XX Medicine, social security, and occupational disabilities in Spain in the first half of the twentieth century
En el presente trabajo, utilizando fuentes legislativas, mĂ©dicas, de algunas instituciones (CRS, IRS, INP, Irpit y ClĂnica del Trabajo), prensa general y obrera, se estudia el abordaje del problema de los invĂĄlidos del trabajo durante la primera mitad del siglo XX. Se trata de poner de relieve cĂłmo junto a medidas de protecciĂłn social se fue generando y articulando una atenciĂłn mĂ©dica especializada del accidentado que tendrĂa como objetivo final la reintegraciĂłn del invĂĄlido del trabajo a la sociedad.<br>Relying on legislative, medical, institutional, media, and labor sources, the article examines how the issue of worker disabilities was addressed during the first half of the twentieth century. It shows how specialized medical care developed and evolved, along with a social safety network, with the ultimate aim of integrating those with occupational disabilities back into work and society
