In search of disambiguation: development of eye drop bottle sleeves to aid in identification and survey among possible users. A cross-sectional study

BACKGROUND: Considerable numbers of individuals present low vision, blindness, illiteracy and other conditions that could possibly impair their identification of medications, such as eye drops. Through helping these individuals to identify their eye drops, they can achieve greater autonomy. Misidentification can be avoided through use of multisensory sleeves that can be adapted to most eye drop bottles. Correct use of eye drops is important for preventing progression of diseases like glaucoma that could potentially lead to blindness. OBJECTIVE: To develop bottle sleeves to aid in identification of eye drops and then interview a group of possible users to evaluate the acceptance of the solution. DESIGN AND SETTING: Cross-sectional survey performed at an ophthalmological clinic in São Paulo (SP), Brazil. METHODS: We describe the development of multisensory sleeves to assist in identification of eye drops. To assess the acceptance of this solution, we interviewed 18 patients who were currently using three or more types of eye drops. RESULTS: We developed four prototypes for eye drop bottle sleeves and conducted an acceptance test on them. Most of the patients who answered the survey about the sleeves were elderly. Most (95%) reported believing that the sleeves would help reduce the risk of mixing up eye drops with other medications that also dispense drops. They also believed that these would increase their autonomy in using eye drops. CONCLUSION: The solution presented was well accepted and may help increase safety in using eye drops through preventing misidentification.

Godoy & Godoy Compression Sleeve in the Treatment of Arm Lymphedema: New Concepts for Materials

ABSTRACT The aim of this work was to study on a new low-elastic textile that fulfilled the criteria of fabrics for the manufacture of compression garments to treat lymphedema. The evolution of Godoy & Godoy compression sleeves was performed by following the patients treated for arm lymphedema. Sixty-six patients with ages ranging from 35 to 83 years and a mean of 58.8 years were included in this study. Diagnosis, by the clinical evaluation confirmed by the volumetry, was defined as a volume difference of more than 200 mL between the arms. All the participants were submitted to treatment sessions once, or two times weekly in an outpatient setting. The material used for the compression sleeve in this study was commercialized in Brazil under the name of Gorgurão(r). When high alterations in the pattern of sleeves were made, the patients were monitored by weekly volumetric assessments. The criterion to maintain the modifications in the design was that the hand did not present with edema. By the end of the study, the design of the sleeve was changed so as not to use compression therapy of the hands in 81.8% of the cases; 12.2% continued with compression of the hand, 3.0% stopped using compression completely and 3.0% used only a glove. Thus, Godoy & Godoy compression sleeves could be an efficient option for compression in the treatment of arm lymphedema as they provided better independence in day-to-day activities.

Application of cotton rolls as protective sleeves of endodontic files / 实用口腔医学杂志

The effects of cotton roll and the traditional gauze wrapper in the protection of endodontic files were observed.Cotton roll showed firm protection and feasible operation advantages,it was more effective than gauze wrapper in the protection of endodontic files(P<0.01).

Underwater digital image measurement using lens sleeves / 医用生物力学

Objective To explore the mechanical testing technique suitable for biological materials under water environment. Methods Based on digital image correlation (DIC) method, the unique lens sleeves which can avoid the distortion caused by underwater photography was designed, and this technique was applied to determining mechanical properties of the fish scales. Results The experiment on translation of the water sink indicated that the use of the designed lens sleeves could effectively reduce errors for underwater measurement with high precision; the mechanical testing on fish scales showed that different regions of the fish scales had obviously different mechanical properties, but the differences induced by regions of the dehydrated fish scales were significantly reduced. Conclusions The designed lens sleeves in this study can be applied to image acquisition effectively, and determination of mechanical properties of the biological materials under water environment was achieved using DIC method.

Effect of ivaradine on hyperpolarization activated cation current in canine pulmonary vein sleeve cardiomyocytes with atrial fibrillation / 老年心脏病学杂志（英文版）

Objective To study the effect of ivabradine on hyperpolarization activated cation current in canine pulmonary vein(PY) sleeve cardiomyocytes with atrial fibrillation.Methods Dissociation of PVs yielded single cardiomyocytes from a Landengorff column without or with pacemaker activity from long-term rapidly atrial pacing (RAP) canines.If current was measured with the whole-cell patch-clamp technique.Results Compared with the control group,the rapidly atrial pacing canine PV cardiomyocytes had spontaneous diastolic depolarization and had larger If densities.Ivabradine (Iva,1 μM),a selective inhibitor of the If current,markedly reduced If currents in the RAP from -2.66±0.4 pA/pF to -1.58±0.1 pA/pF at the test potential of-120 mV (P＜0.01,n=12).Inhibition effect of Iva of If current showed concentration-dependent range from 0.1 to 10.0μM,with IC50 of 2.2 μ M ( 1.8-2.9 μM,95% CL).Furthermore,V1/ of steady-state activated curve was shifted from -84.3±4.9 mV to -106.9±3.4 mV and k value of steady-state activated curve was changed from 12.1+2.6 mV to 9.9±3.4 mV by the application of.1.0 μM Iva ( P＜0.01,n=12).Conclusions Our study revealed that Ivarbadine may significantly decrease If of rapidly atrial pacing pulmonary vein sleeve ceUs with atrial fibdllation.(J Geriatr Cardiol 2008;5:39-42)
