Dual Nanostructured Lipid Carriers/Hydrogel System for Delivery of Curcumin for Topical Skin Applications.

This work focuses on the development and evaluation of a dual nanostructured lipid carrier (NLC)/Carbopol®-based hydrogel system as a potential transporter for the topical delivery of curcumin to the skin. Two populations of different sized negatively charged NLCs (P1, 70-90 nm and P2, 300-350 nm) were prepared and characterized by means of dynamic light scattering. NLCs presented an ovoid platelet shape confirmed by transmission electron microscopy techniques. Curcumin NLC entrapment efficiency and release profiles were assessed by HPLC (high pressure liquid chromatography) and spectrophotometric methods. Preservation and enhancement of curcumin (CUR) antioxidant activity in NLCs (up to 7-fold) was established and cell viability assays on fibroblasts and keratinocytes indicated that CUR-NLCs are non-cytotoxic for concentrations up to 10 µM and exhibited a moderate anti-migration/proliferation effect (20% gap reduction). CUR-NLCs were then embedded in a Carbopol®-based hydrogel without disturbing the mechanical properties of the gel. Penetration studies on Franz diffusion cells over 24 h in CUR-NLCs and CUR-NLCs/gels demonstrated an accumulation of CUR in Strat-M® membranes of 22% and 5%, respectively. All presented data support the use of this new dual CUR-NLC/hydrogel system as a promising candidate for adjuvant treatment in topical dermal applications.

Avaliação da satisfação e das preferências do doente com o diário em cuidados intensivos / Assessment of patient satisfaction and preferences with an intensive care diary

RESUMO Objetivos: Avaliar a satisfação dos doentes internados em uma unidade de cuidado intensivo com o diário e analisar possíveis pontos de melhoria deste instrumento. Métodos: Estudo retrospectivo observacional, decorrido entre março de 2014 e julho de 2017, em uma unidade de cuidado intensivo polivalente de um hospital distrital. Foi iniciado o diário em doentes sedados por 3 ou mais dias. Depois de 3 meses da alta, foi avaliada a satisfação deles por meio de um questionário. O doente que concordou com as cinco afirmações que visavam avaliar esclarecimento, preenchimento de lacunas de memória, ajuda na recuperação, tranquilização e recomendação da intervenção foi definido como satisfeito. Resultados: Foram incluídos 110 doentes, dos quais 55 responderam o questionário. Destes, 36 (65,5%) foram classificados como satisfeitos. Cada item teve uma resposta positiva em mais de 74% dos casos. Sugeriram o aumento do número de fotografias 60% dos participantes. Não foram encontradas diferenças estatisticamente significativas na análise de subgrupos (idade, sexo, tempo de sedação e ventilação, tempo de diário, gravidade à admissão, delirium, depressão ou ansiedade na unidade de cuidado intensivo). Conclusões: A maioria dos doentes mostrou-se satisfeita com o diário, sugerindo, no entanto, o aumento do número de fotografias.

ABSTRACT Objectives: To evaluate the satisfaction of patients admitted to the intensive care unit using a diary and analyze possible points for improving this instrument. Methods: This was an observational, retrospective study, conducted between March 2014 and July 2017, in a multidisciplinary intensive care unit of a district hospital. The diary was implemented in patients sedated for 3 or more days. Three months after discharge, their satisfaction was assessed using a questionnaire. A patient who agreed with the 5 statements assessing the diary's help in clarifying the intensive care unit stay, in filling memory gaps, in recovery, in reassurance, and in the recommendation of this intervention was defined as satisfied. Results: A total of 110 patients were included, of whom 55 answered the questionnaire. Of these, 36 (65.5%) were classified as satisfied. Each item had a positive response in more than 74% of cases. A total of 60% of the participants suggested increasing the number of photographs. No significant differences were found in the subgroup analysis (age, sex, duration of sedation and ventilation, length of diary keeping, severity on admission, or delirium, depression, or anxiety in the intensive care unit). Conclusions: Most patients were satisfied with the diary but suggested an increase in the number of photographs.

Low COST surgery setting for one-operational port laparoscopic hysterectomy surgery with ordinary laparoscopic instruments: preliminary results.

BACKGROUND: Hysterectomy dates back to 120BC and is the second most commonly performed gynecological surgery in the world. Cosmetic demands and the necessity of rapid return to work have contributed to the minimally invasive laparoscopic approach for hysterectomy. The majority of reports describe the use of three or four incisions to perform the surgery (two or three for manipulation and one for optics). METHODS: This work describes our experience with using only two ports for 11 patients who underwent video-laparoscopic hysterectomy surgery. One port was used for the optical system, and the second was used for manipulation. Early and late surgery complications, as well as the time to return to work and daily activities, were assessed. RESULTS: The mean age of the patients was 41.4 years old (range 16 to 52 years) and the mean uterine weight was 133.54 g, ranging from 35 g and 291 g. The operative time ranged from 30 to 60 minutes (average 46.4 minutes) and the hospital stay ranged between 24 and 48 hrs. No intraoperative complications occurred, and no early or late postoperative complications were recorded. Patients reported minimal pain during the first 24-48 hrs in the hospital. Patients returned to their daily activities within seven days after surgery. Clinical care follow-up continued until the 40th postoperative day. CONCLUSION: The laparoscopic hysterectomy technique with a single port for manipulation is a feasible procedure when the uterine weight is not greater than 400 mg with little postoperative pain. The patients had an early return-to-work and daily activities and a better cosmetic outcome. These preliminary data led us to make the one-operative port laparoscopic hysterectomy the procedure of choice for patients with a low uterine weight.
