Underserved populations, including racial/ethnic minorities, individuals with low socioeconomic status, and individuals with physical disabilities, are less likely to engage in sufficient moderate to vigorous physical activity (MVPA) and are thus at increased risk of morbidity and mortality. These populations face unique challenges to engaging in MVPA. Learning how to overcome these challenges is a necessary first step in achieving health equity through health promotion research. In this review of the literature, we discuss issues and strategies that have been used to promote MVPA among individuals from underserved populations, focusing on recruitment, intervention delivery, and the use of technology in interventions. Physical activity promotion research among these vulnerable populations is scarce. Nevertheless, there is preliminary evidence of efficacy in the use of certain recruitment and intervention strategies including tailoring, cultural adaptation, incorporation of new technologies, and multilevel and community-based approaches for physical activity promotion among different underserved populations.

The article discusses the technologies, history on accessibility, and facts on the deaf and hearing loss (DHH) communities which can be tapped by film exhibitors in the U.S. It states that movie captioning access for DHH communities audiences began under the auspices of Tripod, an educational program for DHH children in Burbank, California, in 1993. It adds that DHH people have embraced the coming of digital technology and its various applications such as Hearing Accessible Technology in 2011.

Uranium (U) concentrations and activity ratios (δ234U) of authigenic carbonates are sensitive recorders of different fluid compositions at submarine seeps of hydrocarbon-rich fluids (“cold seeps”) at Hydrate Ridge, off the coast of Oregon, USA. The low U concentrations (mean: 1.3 ± 0.4 μg/g) and high δ234U values (165–317‰) of gas hydrate carbonates reflect the influence of sedimentary pore water indicating that these carbonates were formed under reducing conditions below or at the seafloor. Their 230Th/234U ages span a time interval from 0.8 to 6.4 ka and cluster around 1.2 and 4.7 ka. In contrast, chemoherm carbonates precipitate from marine bottom water marked by relatively high U concentrations (mean: 5.2 ± 0.8 μg/g) and a mean δ234U ratio of 166 ± 3‰. Their U isotopes reflect the δ234U ratios of the bottom water being enriched in 234U relative to normal seawater. Simple mass balance calculations based on U concentrations and their corresponding δ234U ratios reveal a contribution of about 11% of sedimentary pore water to the bottom water. From the U pore water flux and the reconstructed U pore water concentration a mean flow rate of about 147 ± 68 cm/a can be estimated. 230Th/234U ages of chemoherm carbonates range from 7.3 to 267.6 ka. 230Th/234U ages of two chemoherms (Alvin and SE-Knoll chemoherm) correspond to time intervals of low sealevel stands in marine isotope stages (MIS) 2, 4, 5, 6, 7 and 8. This observation indicates that fluid flow at cold seep sites sensitively reflects pressure changes of the hydraulic head in the sediments. The δ18OPDB ratios of the chemoherm carbonates support the hypothesis of precipitation during glacial times. Deviations of the chemoherm δ18O values from the marine δ18O record can be interpreted as to reflect temporally and spatially varying bottom water and/or vent fluid temperatures during carbonate precipitation between 2.6 and 8.6°C.

Objectives: This study aims to analyze the in-hospital complication rates in patients with human immunodeficiency virus (HIV) following primary total knee (TKA) and total hip arthroplasty (THA)., Patients and Methods: This retrospective study included a total of 37 patients including 11 patients undergoing TKA (11 males; mean age: 60.8±16.0 years; range, 48 to 80 years) and 26 patients undergoing THA (23 males, 3 females; mean age: 49.9±11.5 years; range, 35 to 70 years) between January 2010 and December 2019. The patients were evaluated in terms of body mass index (BMI), American Society of Anesthesiology (ASA) scores, pre and postoperative blood tests, indications for surgery, operative time, length of hospital stay, and in-hospital complications., Results: The overall in-hospital complication rate following primary TKA (n=2, 18.2%) and THA (n=2, 7.7%) was 10.8%. Following TKA, one patient had deep vein thrombosis and one patient developed acute renal failure. In the THA group, postoperative delirium and trochanteric fracture were noted., Conclusion: The in-hospital complication rates increased in HIV-positive patients following TKA and THA. The risk of complications can be mitigated with the aid of a better interdisciplinary cooperation and thorough surgical planning.
