Associations between volunteering and cognitive impairment: The moderating role of race/ethnicity

Yi Wang, Roger Wong, Takashi Amano, Huei‐Wern Shen

Health & Social Care in the Community > 30 > 6 > e4433 - e4441

Although volunteering has been shown to benefit cognitive health, there is a paucity of evidence on informal volunteering and subjective measures of cognitive impairment. Also, little is known about whether such relationships vary by race/ethnicity. This study aimed to examine the associations of both formal and informal volunteering with older adults' objective and subjective cognition and explore...

Relationship between dementia, COVID‐19 risk, and adherence to COVID‐19 mitigation behaviors among older adults in the United States

Roger Wong, Margaret Anne Lovier

International Journal of Geriatric Psychiatry > 37 > 6 > n/a - n/a

Thorium chelators for targeted alpha therapy: Rapid chelation of thorium‐226

Maryline G. Ferrier, Yawen Li, Ming‐Kuan Chyan, Roger Wong, more

Journal of Labelled Compounds and Radiopharmaceuticals > 63 > 12 > 502 - 516

One of the main challenges in targeted alpha therapy is assuring delivery of the α‐particle dose to the targeted cells. Thus, it is critical to identify ligands for α‐emitting radiometals that will form complexes that are very stable, both in vitro and in vivo. In this investigation, thorium‐227 (t_1/2 = 18.70 days) chelation of ligands containing hydroxypyridinonate (HOPO) or picolinic acid (pa) moieties...

Perceived Benefits of Participation and Risks of Soil Contamination in St. Louis Urban Community Gardens

Roger Wong, Leah Gable, Zorimar Rivera-Núñez

Journal of Community Health > 2018 > 43 > 3 > 604-610

Community gardens are credited for promoting health within neighborhoods, by increasing healthy food intake and exercise frequency. These benefits, however, are potentially undermined as urban soils are often contaminated from industrial legacies. The purpose of this study was to examine the perceived benefits of participation and risks of soil contamination within urban community gardens, and factors...

Novel technique for removal of persistent subretinal fluid following nondrain retinal detachment surgery

Roger Wong, Giancarlo Dell'Aversana Orabona, Francesca Simonelli, Catherine Howard

Taiwan Journal of Ophthalmology > 2016 > 6 > 4 > 199-200

This manuscript describes a case of successful reattachment of a macular-off retinal detachment following optical coherence tomography-guided internal drainage of retained subretinal fluid following a nondrain method. To date, there has not been any documented treatment option for this common phenomenon. This novel technique describes a method to remove such fluid and successfully appose the retina...

Drugs or Dancing? Using Real-Time Machine Learning to Classify Streamed “Dabbing” Homograph Tweets

Antonio A. Ginart, Sanmay Das, Jenine K. Harris, Roger Wong, more

2016 IEEE International Conference on Healthcare Informatics (ICHI) > 10 - 13

2016 IEEE International Conference on Healthcare Informatics (ICHI)

Dabbing is a new and popular method of using marijuana that involves inhaling vapors from heating marijuana concentrates. As the emergence of legal, regulated markets continues in the U. S., it is possible that dabbing marijuana concentrates will gain traction. Dabbing may present new hazards to marijuana users including increased risk of fires from igniting extracts with butane and increased incidence...

Procedia Computer Science > 2015 > 44 > Complete > 125-134

The Ocean Voyager exhibit residing at the Georgia Aquarium Inc. (GAI) is one of the largest reef gallon aquariums in the world, with a capacity greater than 6.2M gallons. Reef aquariums are closed systems and must compensate by ‘turning over’ their complete volume of water many times a day through biological, chemical, and mechanical filtration. Due to the Georgia Aquarium being a non-profit organization,...

Consecutive toxic anterior segment syndrome in combined phaco-vitrectomy

Manoharan Shunmugam, Charles E. Hugkulstone, Roger Wong, Tom H. Williamson

International Ophthalmology > 2013 > 33 > 3 > 289-290

Toxic anterior segment syndrome (TASS), though rare, has been well documented following anterior segment surgery but not following vitrectomy (Monson et al., J Cataract Refract Surg 18:184–189, 1992). It typically presents within 24 h of uncomplicated cataract surgery with minimal or no pain and intense anterior segment inflammation (Monson et al. 1992). Various exogenous chemicals have been identified...

To understand the natural history of macular folds using serial spectral-domain optical coherence tomography (SD-OCT). Prospective case series. Serial OCTs were performed using Topcon 3D OCT. The main outcome measures were: patient demographics; preoperative, perioperative, and postoperative details; serial SD-OCTs; and length of follow-up. Ten patients who underwent standard 3-port pars...

Phosphatidylcholine/deoxycholate lipolysis and hyaluronic acid augmentation to enhance nonsurgical lower facial contouring using botulinum toxin type A

Garsing Roger Wong, Wen‐Pei Chen

Journal of Cosmetic Dermatology > 10 > 2 > 159 - 162

Botulinum toxin type A can produce dramatic improvements in patients with benign masseteric hypertrophy but this method alone is not as effective for patients with a rounded lower face. The paper describes the effective use of selective lower jowl phosphatidylcholine/deoxycholate lipolysis and chin, cheek, and nose augmentation with hyaluronic acid to refine cosmetic lower facial contouring using...

Purpose: To classify the clinical characteristics that might identify patients who may not require next‐day follow‐up following routine vitreoretinal intervention. Methods: Prospective case series. Results: The only statistically significant factors for raised intraocular pressure (IOP) were gas tamponade and preoperative raised IOP. 44.7% (17/38) of patients with preoperative IOP ≥ 20 mmHg had...

To describe the use of intravitreal bevacizumab in idiopathic retinal vasculitis prior to vitrectomy and delamination. A young healthy male presented with idiopathic retinal vasculitis. His condition was refractory to panretinal photocoagulation and systemic steroids. The progression of his condition necessitated vitrectomy and delamination. Intravitreal bevacizumab was used to facilitate the surgical...
