Stair Use

Purpose: Evaluate the incremental impact of environmental stairwell enhancements on stair usage in addition to prompts. Design: Phased, nonrandomized, quasi-experimental intervention. Setting: Two 6-story and one 8-story municipal government office buildings—each with 2 stairwells. Participants: Approximately 2800 municipal employees and 1000 daily visitors. Intervention: All stairwells received door wraps and point-of-decision and wayfinding prompts. Environmental enhancements were installed in 1 stairwell in each of the 2 buildings: wall paint, upgraded stair treads and handrails, artwork, light-emitting diode (LED) lighting, fire-rated glass doors, and removal of security locks on at least the ground floor. Measures: Staff surveys and focus groups, electronic and direct measures of stair and elevator use occurred at baseline and over 3 years of phased implementation and follow-up. Analysis: Change in the proportion of vertical movement by stairs using χ2 analysis. Results: The prompts were associated with a significant increase in stair use (odds ratio [OR] = 1.36; 95% confidence interval [CI]: 1.31-1.41), with an average absolute increase of 3.2%. Environmental enhancements were associated with an additional significant increase in stair use (OR = 1.31; 95% CI: 1.25-1.37) beyond prompts alone with an average absolute increase of a further 3.5% that was sustained for 1 year. The initial increases in stair use with prompts alone were not sustained. Conclusion: Implementing environmental stairwell enhancements in office buildings increased stair usage in a sustained manner beyond that achieved by prompts alone.

Experimental Study Design

Background:This study tested the effectiveness of a stair use promotion strategy in visible and hidden stairwells during intervention and post intervention follow up.Methods:A quasi-experimental study design was used with a 1 week baseline, a 3 week intervention, and post intervention at 2 and 4 weeks in 4 university buildings in San Antonio, Texas with stairwells varying in visibility. Participants were students, faculty, staff, and visitors to the 4 buildings. A total of 8431 observations were made. The intervention incorporated motivational signs with direction to nearby stairwells placed by elevators to promote stair use. Stair and elevator use was directly observed and recorded. Logistic regression analyses were used to test whether stair versus elevator use varied by intervention phase and stairwell visibility.Results:Stair use increased significantly (12% units) during the intervention period and remained above baseline levels during post intervention follow-up. At baseline, visible stairs were 4 times more likely to be used than hidden stairs; however, the increase in stair use during intervention was similar in both types of stairwells.Conclusions:Motivational and directional signage can significantly increase stair use on a university campus. Furthermore, stairwell visibility is an important aspect of stair use promotion.

AbstractPhotography for preoperative analysis and follow-up is indispensable for the facial plastic surgeon. The use of strobe flash units, light-emitting diode (LED) lamps, and their position related to axis of the patient can affect the nasal contours and nasal measurements. The aim of this study was to compare the rhinoplasty pictures taken under three different lighting settings and two different positioning at 30- and 45-degree angles, and with direct measurements taken by caliper from the subjects. Standardized rhinoplasty pictures from 10 patients were taken in frontal view in a studio. These pictures were taken under three different lighting settings: built-in flash of the camera, two strobe flashes, and two LED continuous lights placed at 30 to 45 degree angles to the patient. All the pictures were uploaded to Rhinobase 2.0. In five subjects, direct measurements were done by using a Vernier caliper and compared with the computer measurements. In this study, when comparing the light sources and the angles without taking single flash into account, no relation was found between strobe lights at 30 and 45 degrees and between LED lights at 30 and 45 degrees regarding tip width, base bony width, dorsum width, interalar width, and nasal length. However, a statistically significant difference was found when the angle was changed from 30 to 45 degrees for tip width, interalar width and nasal length. The use of two LED continuous lights or two strobe lights in a studio setting has given similar results. Changing the angles of the light sources from 30 to 45 degrees affected only the tip width and the interalar width; otherwise the rest of the nasal measurements did not show any significant changes. The pictures taken at 45-degree angles to the subject showed the closest values to the direct measurements done on the patient

SUMMARY This clinical report describes a restorative technique used to replace two Class II resin composite restorations on the upper premolars. A sectional matrix band was used in conjunction with an elastic ring (Composi-Tight) to obtain tight proximal contact. A nanofilled resin composite (Filtek Supreme Ultra) was incrementally applied using oblique layers to reduce the C-factor, each layer being no more than 2 mm thick, and then light cured for 20 seconds with a light-emitting diode lamp (EliparFreeLight 2 LED Curing Light) with a power density of 660 mW/cm2. A centripetal technique was used to restore the lost tooth structure from the periphery toward the center of the cavity in order to achieve a better contour and anatomy with less excess, thereby minimizing the use of rotary instruments during the finishing procedures. Finally, the resin composite restorations were finished and polished, and a surface sealer (Perma Seal) was applied to fill small gaps and defects that may have been present on the surfaces and margins of the restorations after the finishing and polishing procedures.

Introduction: Neonatal hyperbilirubinemia is one of the most common problem encountered during the neonatal period. Phototherapy is a widely accepted, cheap, non-invasive relatively safe and effective method of treatment for neonatal hyperbilirubinemia. Aim: To compare the efficacy of Light Emitting Diode (LED) phototherapy vs Conventional Phototherapy for treatment of neonatal hyperbilirubinemia in healthy term neonates. Materials and Methods: A quasi experimental study was conducted in Neonatal Intensive Care Unit and Post-natal wards in a tertiary care hospital affiliated to Medical College and Hospital, Ahmedabad, Gujarat from July 2018 to April 2019 with a sample size of 135 in each group. They were assessed clinically by Kramers method just before initiation of phototherapy, then using Transcutaneous Bilirubinometer (TCB) Total Serum Bilirubin (TSB) level was measured. Bilirubin assessment by these methods were done for every neonate before initiation of phototherapy and then again repeated after 24 and 48 hours of phototherapy. Data was collected and analysed in Microsoft (MS) excel Statistical Package for the Social Sciences (SPSS) 0.26. Chi-square test was used for comparison. Results: In the present study, 158 (58.51%) babies were male and 112 (41.48%) babies were female. Initially, LED was found to be better than Compact Fluorescent (CFL) conventional phototherapy on comparing the average fall in the serum bilirubin level from baseline during the first 24 hours however no such difference in the efficacy between the two light sources was seen after a period of 48 hours. Total 9 (6.66%) patients developed rebound hyperbilirubinemia after completion of conventional phototherapy whereas 14 (10.37%) developed rebound hyperbilirubinemia after completion of 48 hours of LED phototherapy. Conclusion: LED and conventional phototherapy were equally efficacious in managing non haemolytic hyperbilirubinemia in healthy term neonates.

Background: Eyebrow loss in the course of frontal fibrosing alopecia (FFA) is becoming a growing issue among older females. It has a considerable negative impact on patients’ quality of life. Since there is no standardized treatment, photobiomodulation with light-emitting diodes (LEDs) could be an option. Here we assess, for the first time, the efficacy of LED therapy in the treatment of eyebrow loss in females with FFA. Methods: 16 female patients with FFA aged 60–74 years were enrolled in the study. LED therapy was performed once a week for a 10-week session. The LEDs’ effectiveness was assessed at the baseline, after 10 irradiations, and 6 months after the end of treatment during a follow-up visit. Results: The therapy was well tolerated. After 10 irradiations, the total eyebrow hair count increased significantly, as did the number of thick hairs and mid-thick hairs (p = 0.002, p = 0.002, and p = 0.044, respectively). During the follow-up visit, the total number of eyebrow hairs remained significantly higher than before treatment (p = 0.002). Conclusion: The study revealed that LED therapy seems to be a novel and promising therapeutic option for eyebrow loss in patients with FFA. It is safe and well tolerated and leads to clinically and cosmetically acceptable improvement.
