Smart device interest, perceived usefulness, and preferences in rural Alabama seniors.

Limited data exist on the preferences for smart home devices in rural Americans. We examined the interest, usefulness, and pleasantness of various smart home interfaces and determined whether they differed by ethnicity, rurality, age, and gender. A total of 118 older adults living in the rural Deep South completed a survey instrument that assessed interest in various smart home applications and was queried about the perceived usefulness and perceived ease of use of screen, voice, and robot interfaces in 7 distinct scenarios. Personality data was collected via the Big Five Inventory. Technology readiness was measured using a technological readiness instrument. Participants were primarily female (81%), rural (76%), African American (69%), and aged 65-74 years old (51%). Participants were recruited from a total of 5 cities in West Alabama within the Black Belt. Data was collected before COVID-19 (July 2018 through July 2019).

Community Asset Mapping in Public Health: A Review of Applications and Approaches.

Though Community Asset Mapping (CAM) has been widely used in community-development and applied to public health interventions, little has been done to synthesize the current state of this approach. This paper reports the findings from a scoping review of research where CAM was applied to public health practice and research initiatives. We identified and reviewed 28 articles featuring studies that used asset mapping for public health purposes. Overall, we found that the purpose and methods related to asset mapping varied widely across studies. Given the potential benefits of asset mapping and its relevance to social work principles, researchers and public health professionals should approach asset mapping with the same level of attention, rigor, and ethics as other research methodologies or intervention design. There is an obligation to engage in asset mapping in ways that promote our ethical principles of service, dignity, integrity, and competence.

Fall Risk and Utilization of Balance Training for Adults With Symptomatic Knee Osteoarthritis: Secondary Analysis From a Randomized Clinical Trial.

BACKGROUND AND PURPOSE: Knee osteoarthritis (KOA) is a common disease that hinders activity participation in older adults. Associated symptoms and physiological changes can increase risk of falling in individuals with KOA. Balance training can decrease fall risks in older adults. Limited evidence exists regarding utilization of balance training in physical therapy (PT) for this population. This secondary data analysis investigated the proportion of participants at high risk for falling in the PhysicAl THerapy vs. INternet-based Exercise Training for Patients with Osteoarthritis (PATH-IN) study and the frequency with which balance training was utilized as an intervention in PT. METHODS: PATH-IN study participants (N = 344) performed the Four-Stage Balance Test and the Timed Up and Go (TUG) test during baseline assessment. Participants were randomly allocated to PT, an Internet-based exercise program, or a control group. Participants were classified as being at high risk for falling if they did not progress to the single-leg stance (SLS) during the Four-Stage Balance Test, were unable to maintain SLS for 5 seconds, or took longer than 13.5 seconds to complete the TUG test. The proportion of participants at high risk for falling was calculated for all participants and separately for those allocated to PT. In addition, PT notes were coded for balance training and the frequency of balance training utilization was calculated. RESULTS AND DISCUSSION: Upon enrollment, 35.5% (N = 122) of all participants and 36.2% (N = 50) of those allocated to PT were at high risk for falling. Of participants allocated to PT with documentation available for coding (N = 118), 35.5% (N = 42) were at high risk for falling. Balance training was provided to 62.7% (N = 74) during at least one PT session. Of those classified as being at high risk for falling, 33.3% (N = 14) did not receive balance training. CONCLUSIONS: The finding of high fall risks in more than one-third of all participants with KOA is consistent with previous reports of a higher risk of falling in this population. Many PT participants did receive some balance training; however, one-third of participants at high risk for falling did not. Balance training for individuals with KOA at high risk for falling may be underutilized.

In vivo characterization of connective tissue remodeling using infrared photoacoustic spectra.

Premature cervical remodeling is a critical precursor of spontaneous preterm birth, and the remodeling process is characterized by an increase in tissue hydration. Nevertheless, current clinical measurements of cervical remodeling are subjective and detect only late events, such as cervical effacement and dilation. Here, we present a photoacoustic endoscope that can quantify tissue hydration by measuring near-infrared cervical spectra. We quantify the water contents of tissue-mimicking hydrogel phantoms as an analog of cervical connective tissue. Applying this method to pregnant women in vivo, we observed an increase in the water content of the cervix throughout pregnancy. The application of this technique in maternal healthcare may advance our understanding of cervical remodeling and provide a sensitive method for predicting preterm birth.

Transvaginal fast-scanning optical-resolution photoacoustic endoscopy.

Photoacoustic endoscopy offers in vivo examination of the visceral tissue using endogenous contrast, but its typical B-scan rate is ∼10 Hz, restricted by the speed of the scanning unit and the laser pulse repetition rate. Here, we present a transvaginal fast-scanning optical-resolution photoacoustic endoscope with a 250-Hz B-scan rate over a 3-mm scanning range. Using this modality, we not only illustrated the morphological differences of vasculatures among the human ectocervix, uterine body, and sublingual mucosa but also showed the longitudinal and cross-sectional differences of cervical vasculatures in pregnant women. This technology is promising for screening the visceral pathological changes associated with angiogenesis.

IL-22 and IL-20 are key mediators of the epidermal alterations in psoriasis while IL-17 and IFN-gamma are not.

Psoriasis is a common chronic skin disease with a largely unknown pathogenesis. We demonstrate here that transgenic over-expression of interleukin (IL)-22 in mice resulted in neonatal mortality and psoriasis-like skin alterations including acanthosis and hypogranularity. This cutaneous phenotype may be caused by the direct influence of IL-22 on keratinocytes, since this cytokine did not affect skin fibroblasts, endothelial cells, melanocytes, or adipocytes. The comparison of cytokines with hypothesized roles in psoriasis pathogenesis determined that neither interferon (IFN)-gamma nor IL-17, but only IL-22 and, with lower potency, IL-20 caused psoriasis-like morphological changes in a three-dimensional human epidermis model. These changes were associated with inhibited keratinocyte terminal differentiation and with STAT3 upregulation. The IL-22 effect on differentiation-regulating genes was STAT3-dependent. In contrast to IL-22 and IL-20, IFN-gamma and IL-17 strongly induced T-cell and neutrophilic granulocyte-attracting chemokines, respectively. Tumor necrosis factor-alpha potently induced diverse chemokines and additionally enhanced the expression of IL-22 receptor pathway elements and amplified some IL-22 effects. This study suggests that different cytokines are players in the psoriasis pathogenesis although only the IL-10 family members IL-22 and IL-20 directly cause the characteristic epidermal alterations.

Preliminary findings on a brief friendship-based HIV/STI intervention for urban African American youth: project ORE.

This study presents preliminary findings of a brief friendship-based HIV/STI prevention intervention for urban African American youth. Using a no-control design, we found that the program is feasible, acceptable, and demonstrates promise with regard to changes in HIV/STI-related knowledge, beliefs, social norms, and behavior.
