    Introdução O sugamadex é uma gama ciclodextrina modificada que forma um complexo com os bloqueadores neuromusculares rocurónio e vecurónio, revertendo o bloqueio neuromuscular (BNM) induzido por estes fármacos1,2,3,4. O sugamadex apresentou valor terapêutico acrescentado em relação aos anticolinesterásicos, nomeadamente à neostigmina, para a reversão do BNM causado pelo rocurónio e vecurónio1,3. No Hospital de São José (HSJ) este medicamento foi introduzido em Outubro de 2010 para a reversão do BNM profundo e nas situações de risco de vida imediato associadas a via aérea difícil com impossibilidade de ventilar e de entubar. A dispensa do sugamadex é efectuada por reposição de stock mediante envio de justificação clínica aos Serviços Farmacêuticos (SF). Objetivo Caracterizar a utilização de sugamadex no HSJ: evolução do consumo, serviços clínicos utilizadores e adequação da utilização clínica face às indicações aprovadas pela Comissão de Farmácia e Terapêutica (CFT). Métodos Pesquisa e análise bibliográfica. Recolha, através da do sistema de gestão integrada do circuito do medicamento, dos dados de consumo desde Outubro de 2010 até Junho de 2015, por semestre e por serviço clínico. Recolha das indicações terapêuticas em que o sugamadex foi administrado, no período acima referido, através da consulta das justificações clínicas. Análise retrospectiva dos dados recolhidos. Resultados Apresentação gráfica dos consumos de sugamadex nos serviços utilizadores no período em estudo. Apresentação gráfica das indicações terapêuticas em que foi administrado, por serviço e no período em estudo. Conclusões O consumo de sugamadex tem um evidente crescimento desde o seu início de utilização. A justificação dominante para a utilização do sugamadex é a curarização residual. Verifica-se um alargamento do âmbito de utilização, face às indicações aprovadas pela CFT. Decorridos cinco anos de utilização, justifica-se uma reavaliação das indicações de utilização no HSJ pela CFT. Bibliografia 1. Chambers D, Paulden M, Paton F, Heirs M, Duffy S, Craig D, et al.

    PURPOSE: To evaluate the long-term efficacy of ranibizumab in the treatment of retinal angiomatous proliferation (RAP) and to identify predictors of functional outcome. METHODS: Retrospective case series comprised 79 eyes of 68 consecutive patients with RAP followed up ≥36 months. Primary end-points were best-corrected visual acuity (BCVA) and central macular thickness (CMT) variation at 36 months and at the last visit. RESULTS: Mean follow-up time was 59.8 ± 16.0 months. All eyes were treated with pro re nata ranibizumab, with (n = 33) or without (n = 46) photodynamic therapy (PDT). Stabilization or improvement in BCVA was observed in 50.6% of the patients at 36 months, and in 40.5% at the end of the follow-up, where 20.3% preserved reading vision. A significant decrease in CMT was observed at 36 months (p < 0.001), but not at the end of the follow-up. Geographic atrophy (GA) was present in 59.5% of the eyes at the final visit. Baseline subretinal fluid was associated with better visual outcomes (p = 0.001). Results of combination treatment with intravitreal ranibizumab and PDT did not significantly differ from ranibizumab monotherapy. CONCLUSION: Modest functional outcomes can be expected from the long-term treatment of RAP lesions in clinical practice, most likely due to the advent of GA. Baseline subretinal fluid positively correlated with final BCVA.info:eu-repo/semantics/publishedVersio

    Caracterização isoenzimática de isolados humanos de Leishmania sp (Kinetoplastida: Trypanosomatidae) dos municípios de Rio Preto da Eva e Manaus, Estado do Amazonas

    Twenty-three isolates of Leishmania sp from patients in the municipalities of Rio Preto da Eva and Manaus were characterized and identified by means of isoenzyme electrophoresis and the degree of similarity between the organisms was analyzed. The results indicated that Leishmania guyanensis and Leishmania naiffi were present in these two environments and that the Leishmania naiffi samples were heterogenous

    Genomic Diversity in Two Related Plant Species with and without Sex Chromosomes - Silene latifolia and S. vulgaris

    Genome size evolution is a complex process influenced by polyploidization, satellite DNA accumulation, and expansion of retroelements. How this process could be affected by different reproductive strategies is still poorly understood.We analyzed differences in the number and distribution of major repetitive DNA elements in two closely related species, Silene latifolia and S. vulgaris. Both species are diploid and possess the same chromosome number (2n = 24), but differ in their genome size and mode of reproduction. The dioecious S. latifolia (1C = 2.70 pg DNA) possesses sex chromosomes and its genome is 2.5× larger than that of the gynodioecious S. vulgaris (1C = 1.13 pg DNA), which does not possess sex chromosomes. We discovered that the genome of S. latifolia is larger mainly due to the expansion of Ogre retrotransposons. Surprisingly, the centromeric STAR-C and TR1 tandem repeats were found to be more abundant in S. vulgaris, the species with the smaller genome. We further examined the distribution of major repetitive sequences in related species in the Caryophyllaceae family. The results of FISH (fluorescence in situ hybridization) on mitotic chromosomes with the Retand element indicate that large rearrangements occurred during the evolution of the Caryophyllaceae family.Our data demonstrate that the evolution of genome size in the genus Silene is accompanied by the expansion of different repetitive elements with specific patterns in the dioecious species possessing the sex chromosomes

    Multi-messenger observations of a binary neutron star merger

    On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta
