What are the key milestone events that facilitate sexual identity among persons who experience same-sex attraction? Do those milestone events lead to one outcome, or are multiple outcomes possible with respect to how sexual identity develops and synthesizes over time? This initial pilot study compared 14 religiously-affiliated persons who integrated their experiences of same-sex attraction into a lesbian, gay, or bisexual (LGB) identity synthesis, with 14 religiously-affiliated persons who dis-identified with a LGB-affirming ideology and pursued an alternative identity synthesis. We identified influences that facilitated an individual identifying with LGB-affirming ideologies and the individuals/subcultures that embrace such ideologies, and influences that facilitated an individual dis-identifying with LGB-affirming ideologies and the individuals/subcultures that embrace such ideologies.

Accurate, accessible methods for monitoring and evaluation of improved cookstoves are necessary to optimize designs, quantify impacts, and ensure programmatic success. Despite recent advances in cookstove monitoring technologies, there are no existing devices that autonomously measure fuel use in a household over time and this important metric continues to rely on in-person visits to conduct measurements by hand. To address this need, researchers at Oregon State University and Waltech Systems have developed the Fuel, Usage, and Emissions Logger (FUEL), an integrated sensor platform that quantifies fuel consumption and cookstove use by monitoring the mass of the household’s fuel supply with a load cell and the cookstove body temperature with a thermocouple. Following a proof-of-concept study of five prototypes in Honduras, a pilot study of one hundred prototypes was conducted in the Apac District of northern Uganda for one month. The results were used to evaluate user engagement with the system, verify technical performance, and develop algorithms to quantify fuel consumption and stove usage over time. Due to external hardware malfunctions, 31% of the deployed FUEL sensors did not record data. However, results from the remaining 69% of sensors indicated that 82% of households used the sensor consistently for a cumulative 2188 days. Preliminary results report an average daily fuel consumption of 6.3 ± 1.9 kg across households. Detailed analysis algorithms are still under development. With higher quality external hardware, it is expected that FUEL will perform as anticipated, providing long-term, quantitative data on cookstove adoption, fuel consumption, and emissions.

This study aimed to evaluate the effects of two months of orthokeratology (OK) treatment in the accommodative response of young adult myopes. Twenty eyes (21.8 ± 1.8 years) were fitted with the Paragon CRT® 100 LENS to treat myopia between −1.00 and −2.00 D. Low- and high-contrast visual acuity (LCDVA and HCDVA), central objective refraction, light disturbance (LD), and objective accommodative response (using the Grand Seiko WAM-5500 open-field autorefractometer coupled with a Badal system) were measured at baseline (BL) before lens wear and after 1, 15, 30, and 60 nights of OK. Refractive error correction was achieved during the first fifty days of OK lens wear, with minimal changes afterwards. LD analysis showed a transient increase followed by a reduction to baseline levels over the first 30 nights of treatment. The accommodative response was lower than expected for all target vergences in all visits (BL: 0.61 D at 1.00 D to 0.96 D at 5.00 D; 60 N: 0.36 D at 1.00 D to 0.79 D at 5.00 D). On average, the accommodative lag decreases over time with OK lens wear. However, these differences were not statistically significant (p > 0.050, repeated-measures ANOVA and Friedman test). This shows that overnight OK treatment does not affect objectively measured the accommodative response of young, low myopic eyes after two months of treatment stabilization.

Introduction: Health guidelines suggest that pregnant women should participate in daily physical activity, yet rarely do they meet these guidelines. Means to enhance accessibility of physical activity for pregnant women are required, and yoga has been suggested as a possible method to enhance women’s sense of confidence and competence with physical activity. In this pilot study, our primary aim is to evaluate pregnant women’s perceptions about their lived experience of an intervention which integrates a low-intensity form of physical activity, yoga, into prenatal care; our secondary aim is to evaluate changes in participants’ self-efficacy for physical activity and time spent in physical activity over time. Methods: Held in an outpatient obstetrics department of an urban hospital system in the United States, this pilot study enrolled 16 pregnant women to participate in the intervention throughout their pregnancy. We explored participants’ lived experience of the intervention using qualitative methods (phenomenology). Means, variances, and covariances were calculated for the 2 measures (self-efficacy and time spent in physical activity) over the intervention period. Results: Qualitative findings from focus groups suggest that it is acceptable for prenatal yoga to be integrated into group prenatal care classes and women reported increased confidence with physical activity during pregnancy. Participants did not consider the intervention to fit within the traditional definition of exercise. Women reported increased amounts of time spent in physical activity from baseline to the end of pregnancy, but there were no statistically significant changes in self-efficacy over time. Discussion: The integration of gentle physical activity into the group prenatal care model warrants further attention for potential benefits with regard to maternal physical and mental wellness.

Over Time

The objective of this pilot study was to evaluate a 6-month exercise program completed by 10 older Caribbean Americans. Assessments were done at baseline and 3 and 6 months, and included walks on an instrumented mat at preferred speed, and during street crossing simulations with regular (10 s) and reduced time (5 s). There were no significant differences on preferred walking speed over time. Differences between the street crossing conditions were found only at 6 months. Significant changes over time among the assessments were found only during street crossing with reduced time. Street crossing with reduced time was the only walking condition sensitive to capture changes associated with participating in the exercise program. There was a significant increase in dorsiflexion strength overtime. At 6 months it was significantly higher than at baseline and 3 months. The program was feasible, acceptable, and had some positive effects on walking, knee flexion, and dorsiflexion strength.

People with Parkinson disease (PD) demonstrate improvements in motor function following group tango classes, but report long commutes as a barrier to participation. To increase access, we investigated a telerehabilitation approach to group tango instruction. Twenty-six people with mild-to-moderate PD were assigned based on commute distance to either the telerehabilitation group (Telerehab) or an in-person instruction group (In-person). Both groups followed the same twice-weekly, 12-week curriculum with the same instructor. Feasibility metrics were participant retention, attendance and adverse events. Outcomes assessed were balance, PD motor sign severity and gait. Participant retention was 85% in both groups. Attendance was 87% in the Telerehab group and 84% in the In-person group. No adverse events occurred. Balance and motor sign severity improved significantly over time ( p < 0.001) in both groups, with no significant group × time effects. Gait did not significantly change. Since a priori feasibility criteria were met or exceeded, and there were no notable outcome differences between the two instruction approaches, this pilot study suggests a telerehabilitation approach to group tango class for people with PD is feasible and may have similar outcomes to in-person instruction.

Over Time

A prospective controlled pilot study was undertaken in which Biolite (carbon-coated) ventilation tubes were placed in 44 ears and a conventional silicone tube in the contralateral ear. Long-term follow-up of these patients has revealed little difference in the incidence of tube occlusion or early extrusion. In addition, there were several disadvantages noted with the Biolite tubes: incomplete coating of the tube (especially within the lumen), shedding of the Biolite coating over time, “tattooing” of the tympanic membrane, poor otoscopic visibility, and the higher cost of these tubes. Since the Biolite tube has no documented advantages and, actually, several disadvantages, we believe its use in the treatment of middle ear disorders should be discontinued until significant benefits are demonstrated and present deficiencies are corrected.
