ABSTRACT

Human papillomavirus (HPV) vaccination can dramatically reduce the incidence of HPV-associated cancers. However, HPV vaccination coverage in rural areas is lower than in urban areas, and overall HPV vaccination coverage in the United States remains lower than other adolescent vaccines. We conducted 20 qualitative interviews with adolescent healthcare providers and clinic staff in urban and rural Minnesota and assessed their perspectives on HPV vaccination. Guiding interview topics included: strategies to persuade families to vaccinate their children, the impact of the patient-provider relationship and the clinical environment on vaccination uptake, and provider perceptions of parents' vaccine attitudes. In thematic analysis, all participants reported using common vaccination strategies, such as framing the HPV vaccine in terms of cancer prevention. The analysis also revealed three themes described as occurring uniquely or more intensely in rural communities than urban communities: the rural value of choice or independence, the spread of misinformation, and close-knit, multifaceted patient-provider relationships in clinical practice. Interventions aimed at increasing HPV vaccination should consider the distinctive circumstances of rural healthcare providers and patients.

ABSTRACT

Nicolaou, Laura, Anne Steinberg, Rodrigo M. Carrillo-Larco, Stella Hartinger, Andres G. Lescano, and William Checkley. Living at high altitude and COVID-19 mortality in Peru. High Alt Med Biol. 23:146-158, 2022. Background: Previous studies have reported a lower severity of COVID-19 infections at higher altitudes; however, this association may be confounded by various factors. We examined the association between living at altitude and COVID-19 mortality in Peru adjusting for population density, prevalence of comorbidities, indicators of socioeconomic status, and health care access. Methods: Utilizing administrative data across 196 provinces located at varying altitudes (sea level to 4,373 m), we conducted a two-stage analysis of COVID-19 deaths between March 19 and December 31, 2020, Peru's first wave. We first calculated cumulative daily mortality rate for each province and fit lognormal cumulative distribution functions to estimate total mortality rate, and start, peak, and duration of the first wave. We then regressed province-level total mortality rate, start, peak, and duration of the first wave as a function of altitude adjusted for confounders. Results: There were 93,528 recorded deaths from COVID-19 (mean age 66.5 years, 64.5% male) for a cumulative mortality of 272.5 per 100,000 population between March 19 and December 31, 2020. We did not find a consistent monotonic trend between living at higher altitudes and estimated total mortality rate for provinces at 500 - 1,000 m (-12.1 deaths per 100,000 population per 100 m, 95% familywise confidence interval -27.7 to 3.5) or > 1,000 m (-0.3, -2.7 to 2.0). We also did not find consistent monotonic trends for the start, peak, and duration of the first wave beyond the first 500 m. Conclusions: Our findings suggest that living at high altitude may not confer a lower risk of death from COVID-19.

ABSTRACT

Vestibular-multisensory interactions are essential for self-motion, navigation and postural stability. Despite evidence suggesting shared brain areas between vestibular and somatosensory inputs, no study has yet investigated whether somatosensory information influences vestibular perception. Here, we used signal detection methods to identify whether somatosensory stimulation might interact with vestibular events in a vestibular detection task. Participants were instructed to detect near-threshold vestibular roll-rotation sensations delivered by galvanic vestibular stimulation in one-half of experimental trials. A vibrotactile signal occurred to the index fingers of both hands in half of the trials, independent of vestibular signals. We found that vibrotactile somatosensory stimulation decreased perceptual vestibular sensitivity. The results are compatible with a gain regulation mechanism between vestibular and somatosensory modalities.
