Simulated Hearing Loss In Healthy Young And Older Adults Results In Poor Reaction Time In Older Adults., Victoria Kowalewski, Nicoleta Bugnariu, Rita M. Patterson, Jessica Hartos

Pacific Journal of Health

Emerging evidence links hearing loss to increased fall risk in older adults, yet mechanisms remain unclear. This study examined the impact of simulated hearing loss on reactive balance control in healthy young and older adults. Participants performed dual-task scenario involving auditory sentence repetition and unexpected surface translations. Hearing loss was simulated using Adobe Audition, applying frequency-specific attenuation based on moderate sensorineural hearing loss levels from the literature.

Speech-in-noise performance significantly declined under simulated hearing loss for both age groups (p < .001), confirming effective simulation, but not significant differences were found between age groups. Maximum COP-COM displacement (the scalar distance between Center of Pressure and Center of Mass) increased with perturbation intensity (Level 1 vs. Level 2: p < .001), but no significant differences were found between hearing conditions or age groups (p > .05), suggesting compensatory step execution was preserved.

Reaction time analysis revealed a significant interaction between hearing condition and perturbation level …

Participation And Outcomes Of A Community-Based Fall Prevention Program Before, During And After Covid-19 Pandemic., Bhavana Raja, Preeti Oza

Pacific Journal of Health

Introduction: Several community education programs aim to minimize risk of falling in community-dwelling older adults. However, due to the covid-19 pandemic most of these programs stopped or were delivered virtually. A matter of balance (MOB) is one such program that was delivered virtually during pandemic. The purpose of this study is to assess the differences in outcomes between in-person and virtual MOB program in San Joaquin County of California.

Methods: Participants were recruited from the community. Each MOB course ran for 8 sessions in-person or 9 sessions in the virtual format. A retrospective analysis was conducted on deidentified pre-post survey …

Impact Of 17-Beta Estradiol And Moderate-Intensity Exercise On Mesenteric Arterial Function Of Uc Davis Type-2 Diabetes Mellitus Rats, Md Rahatullah Razan

University of the Pacific Theses and Dissertations

The studies in this dissertation were designed to investigate the impacts of estrogen (17-β estradiol/E2) and moderate-intensity exercise (MIE) on the mesenteric arterial (MA) function of the University of California Davis type-2 diabetes mellitus (UCD-T2DM) Rat model. Our recent report suggests that diabetes impairs MA vasorelaxation in both sexes of the UCD-T2DM model. Particularly, we reported that MA from prediabetic male rats showed a greater impairment compared to that in prediabetic females. However, when females become diabetic, they exhibit a greater vascular dysfunction than males. Therefore, the aim of the first study was to investigate whether female sex hormone, specifically …

Screening Of Physical Activity Levels In Older Adults At A Community-Based Health Fair: A Feasibility Study, David B. Gillette, Preeti Oza, Todd E. Davenport

Pacific Journal of Health

Purpose: The purpose of this study was to assess the feasibility of activity level screenings in community-based health fairs. Additionally, we assessed relationships between participants’ sociodemographics, health-related factors and self-reported activity levels.

Methods: Feasibility was assessed by the time required to conduct screenings and ease of integrating it into the health fair workflow. Physical Therapy students collected responses using Activities Specific Balance Confidence Scale (ABC) and the Physical Activity Level (PAL) items from the National Health and Nutrition Examination Survey.

Results:Screenings increased service and wait times. Participants (N=37, mean age=71.5 years) reported a mean of 4.8 fall risk factors, …

Studies On The Localization And Retention Of Tetracycline Hydrochloride In Ehrlich Ascites Cells, Dale William James

University of the Pacific Theses and Dissertations

The antibiotics have become so widely and successfully used in the practice of medicine that they are now considered to be essential. Among the antibiotics, the tetracycline group has achieved an enviable reputation for dependable medication, In spite of this, there remain several unanswered questions, One of these pertains to the interesting phenomenon for almost selective localization of tetracycline in certain tumor cells or masses, Although there have been numerous publications dealing with this phenomenon, as the following paragraphs will indicate, there is little agreement as to the factors involved. Indeed, there are some sharply conflicting opinions.

The investigations described …
