In vitro cultivation is a technique that allows the production of great amount of plants. However, significant losses may occur during the acclimatization period (ex vitro stage). The objective of this study was to evaluate the effect of paclobutrazol, in the Murashige and Skoog culture medium, on growth, development, and survival of Zygopetalum crinitum plants. The experimental design (both in vitro and ex vitro) was completely randomized with four treatments: three paclobutrazol concentrations (0.5;1.0;and 1.5 mg L-1 active ingredient) and the control (without PBZ). Morphological changes promoted by the paclobutrazol application were observed in the seedlings;however, it did not result in higher seedling survival rates of the Zygopetalum crinitum orchid.

Amaryllis plants (Hippeastrum hybrid, in the family Amaryllidaceae) are cultivated in Brazil mainly for bulb export. Studies about the nutrient accumulation dynamics by the species are yet incipient when considering Brazilian cultivation conditions. The objective was to determine the nutrient accumulation in amaryllis “Orange Souvereign” cultivated in the field. The experimental design was entirely randomized with four replications and 14 collection periods (at 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, and 420 days after planting). Sampled plants were divided into leaves, bulb, and roots, which were used for determination of nutrient accumulation by leaves (aerial part) and bulb + roots (underground part). Nutrient accumulation of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, and Zn was calculated for each collection period, and then represented by curves of macro and micronutrient accumulation, as well as accumulation percentages for each plant part. For most macro and micronutrients, the interval of maximum accumulation fell from 301 to 420 days after planting, matching with the cycle final stage of plants cultivated in the field. Accumulated macronutrients by amaryllis plants along the cultivation cycle was, in g·plant-1: 1.57 N;0.19 P;2.58 K;0.64 Ca;0.20 Mg;and 0.29 S, following the descending order: K > N > Ca > S > Mg > P. Accumulated micronutrients, in mg·plant-1, was: 2.18 B;1.17 Cu;22.33 Fe;2.19 Mn;and 4.09 Zn, following the descending order: Fe > Zn > Mn > B > Cu.

The objective of this study was to analyze the effect of the seasons and indol butyric acid (IBA), as well as the preparation of IBA solutions on rooting growth of “Fine Time” chrysanthemum cuttings. The first experiment was arranged in a 4 × 2 factorial scheme: IBA concentrations (0, 1000, 2000 and 3000 mg·L-1) during summer and winter with 4 replicates of two pots and six cuttings per pot. In the second experiment, the storage of IBA solution (1000 mg·L-1) at 15°C was studied with four replicates of 10 cuttings per plot in a period of four weeks. In the third experiment, dilution and supply of IBA (1000 mg·L-1 or 1000 mg·kg-1) were studied;there were eight treatments: (1) IBA mixed with industrial talc;(2) IBA diluted in 50% alcohol and oven dried at 30°C;(3) IBA diluted in 50% alcohol and oven dried at 70°C;(4) IBA diluted in NaOH and supplied via aqueous solution;(5) IBA diluted in acetone and supplied via aqueous solution;(6) IBA diluted in alcohol 92.8% and supplied via alcoholic solution;(7) IBA diluted in alcohol 50% and supplied via alcoholic solution;(8) IBA mixed and supplied via lanolin;with four replicates of 10 cuttings per plot. Twenty-one days after cutting implementation, the following variables were evaluated: rooting percentage, number, average length and root dry mass. Statistical analysis and time-of-year averages were compared using the Tukey test at 5%;polynomial regression for IBA concentration and preparation data. The means of dilution and delivery were compared by the Scott-Knott test. Treatment with IBA at a concentration of 3000 mg·kg-1 resulted in 90% rooting in the winter and 100% in the summer for all treatments. Results suggest the concentration of 2000 mg·L-1 in the summer and 2000 and 3000 mg·L-1 during the winter provided better quality for the root system. Cuttings treated with IBA diluted in 50% alcohol and oven dried at 30°C showed higher number, length and vigor of the roots.

Antimicrobial resistance(AMR)is a growing phenomenon that poses a major public health challenge worldwide(Dhingra et al.2020;Antimicrobial Resistance Collaborators 2022).The selective pressure exerted in clinical settings has contributed to the longlasting successful dissemination of multidrug-resistant(MDR)Gram-negative bacteria in these environments(Chia et al.2020).

Background: Use of inappropriate amikacin dose is one of the most important factors in inducing toxicity, prolonged hospitalization as well as in increasing patient’s mortality. Objective: The aims of this study are the analysis of amikacin dose, serum level and the examination of the effectiveness of the clinical pharmacologist (CP) therapeutic drug monitoring (TDM) intervention to guarantee the safety of amikacin use. Methods: This is a one-year retrospective observational chart review study, which evaluates amikacin dose, serum drug level, development of adverse effects in patients on amikacin with or without CP TDM consultation. Results: Amikacin was prescribed for 393 complex patients, with median age 83. Amikacin group (AG) included 140 (32%) courses with CP consultation (AG1) and 292 (68%) courses without CP consultation (AG2). The distribution of most study characteristics in both groups was similar including amikacin dose (9-10 mg/kg/day), renal failure (14%) and mortality (12%). Acceptance for CP consultation was in 46% of amikacin courses and dose changes were done in 63% after CP intervention. Prolonged antibiotic course (4.6 ± 1.5 vs 3.8 ± 1.6 days, p < 0.0001) and the patient’s hemodynamic instability (15% vs 7%, p = 0.01) were more frequent in the AG1 compared to the AG2. There was a strong association between CP consultation and prolonged hospitalization (p = 0.005), while no association between it and amikacin adverse effects, renal failure or mortality. Conclusions: There was no trend to reducing amikacin toxicity, days of hospitaliza tion or mortality in patients with CP consultation. CP TDM intervention was more in the management of complicated clinical situations. However, it is necessary to optimize it.
