Embargo end date: 24 February 2018.The role of the Himalayan orography representationin a Regional Climate Model (RegCM4) nested inNCMRWF global spectral model is examined in simulatingthe winter circulation and associated precipitation over theNorthwest India (NWI; 23°–37.5°N and 69°–85°E) region.For this purpose, nine different set of orography representationsfor nine distinct precipitation years (three years eachfor wet, normal and dry) have been considered by increasing(decreasing) 5, 10, 15, and 20% from the mean height(CNTRL) of the Himalaya in RegCM4 model. Validationwith various observations revealed a good improvementin reproducing the precipitation intensity and distributionwith increased model height compared to the resultsobtained from CNTRL and reduced orography experiments.Further it has been found that, increase in heightby 10% (P10) increases seasonal precipitation about 20%,while decrease in height by 10% (M10) results around 28%reduction in seasonal precipitation as compared to CNTRLexperiment over NWI region. This improvement in precipitationsimulation comes due to better representation ofvertical pressure velocity and moisture transport as thesefactors play an important role in wintertime precipitationprocesses over NWI region. Furthermore, a comparison of model-simulated precipitation with observed precipitationat 17 station locations has been also carried out. Overall,the results suggest that when the orographic increment of10% (P10) is applied on RegCM4 model, it has better skillin simulating the precipitation over the NWI region andthis model is a useful tool for further regional downscalingstudies.Peer reviewe
Corticosteroids and other immunosuppressants for immune-related adverse events and checkpoint inhibitor effectiveness in melanoma.
Recent studies indicate an association between immunosuppression for immune-related adverse events (irAEs) and impaired survival in patients who received immune checkpoint inhibitors. Whether this is related to corticosteroids or second-line immunosuppressants is unknown. In the largest cohort thus far, we assessed the association of immunosuppressant type and dose with survival in melanoma patients with irAEs.
Patients with advanced melanoma who received immunosuppressants for irAEs induced by first-line anti-PD-1 ± anti-CTLA-4 were included from 18 hospitals worldwide. Associations of cumulative and peak dose corticosteroids and use of second-line immunosuppression with survival from start of immunosuppression were assessed using multivariable Cox proportional hazard regression.
Among 606 patients, 404 had anti-PD-1 + anti-CTLA-4-related irAEs and 202 had anti-PD-1-related irAEs. 425 patients (70 %) received corticosteroids only; 181 patients (30 %) additionally received second-line immunosuppressants. Median PFS and OS from starting immunosuppression were 4.5 (95 %CI 3.4-8.1) and 31 (95 %CI 15-not reached) months in patients who received second-line immunosuppressants, and 11 (95 %CI 9.4-14) and 55 (95 %CI 41-not reached) months in patients who did not. High corticosteroid peak dose was associated with worse PFS and OS (HR <sub>adj</sub> 1.14; 95 %CI 1.01-1.29; HR <sub>adj</sub> 1.29; 95 %CI 1.12-1.49 for 80vs40mg), while cumulative dose was not. Second-line immunosuppression was associated with worse PFS (HR <sub>adj</sub> 1.32; 95 %CI 1.02-1.72) and OS (HR <sub>adj</sub> 1.34; 95 %CI 0.99-1.82) compared with corticosteroids alone.
High corticosteroid peak dose and second-line immunosuppressants to treat irAEs are both associated with impaired survival. While immunosuppression is indispensable for treatment of severe irAEs, clinicians should weigh possible detrimental effects on survival against potential disadvantages of undertreatment
Políticas e normativas aplicadas às creches municipais do Rio de Janeiro
As primeiras creches foram instaladas no Brasil para reduzir os índices de mortalidade infantil, porém as Doenças Transmitidas por Alimentos vêm aumentando. A Organização Mundial da Saúde (OMS) estima que anualmente ocorram 1,8 milhões de mortes de crianças menores de 5 anos de idade em todo mundo, atribuídas ao consumo de alimentos contaminados. Entretanto, a legislação brasileira não prevê normas específicas de funcionamento para cozinhas de creches. Sendo assim, o objetivo desse estudo é pesquisar as normativas relacionadas ao funcionamento das creches, discutindo os regulamentos sanitários pertinentes à produção de alimentos. Através de uma revisão em páginas eletrônicas de diversos Órgãos, foram levantados regulamentos inerentes ao funcionamento e produção de alimentos em creches. Considerando as vinte e sete legislações encontradas, observa-se uma preocupação com a água, o fornecimento de gêneros, o controle de pragas e vetores, as condições estruturais e as políticas de Alimentação. Apesar disso, nota-se que nem sempre as políticas de vigilância da qualidade da alimentação oferecida nas creches são efetivas, assim como se percebe a ausência de um regulamento específico que determine os critérios de qualidade para uma manipulação segura de alimentos nesses locais
