Partnership between household features and the total well being with the elderly.
Disruptions of circadian motor behavior cause a significant burden for older adults as well as their caregivers and often lead to institutionalization. This cross-sectional study investigates the association between mobility-related behavior and subjectively rated circadian chronotypes in healthy older adults. The physical activity of 81 community-dwelling older adults was measured over seven consecutive days and nights using lower-back-worn hybrid motion sensors (MM+) and wrist-worn actigraphs (MW8). A 30-min and 120-min active period for the highest number of steps (MM+) and activity counts (MW8) was derived for each day, respectively. Subjective chronotypes were classified by the Morningness-Eveningness Questionnaire into 40 (50%) morning types, 35 (43%) intermediate and six (7%) evening types. Analysis revealed significantly earlier starts for the 30-min active period (steps) in the morning types compared to the intermediate types (p ≤ 0.01) and the evening types (p ≤ 0.01). The 120-min active period (steps) showed significantly earlier starts in the morning types compared to the intermediate types (p ≤ 0.01) and the evening types (p = 0.02). The starting times of active periods determined from wrist-activity counts (MW8) did not reveal differences between the three chronotypes (p = 0.36 for the 30-min and p = 0.12 for the 120-min active period). The timing of mobility-related activity, i.e., periods with the highest number of steps measured by hybrid motion sensors, is associated to subjectively rated chronotypes in healthy older adults. The analysis of individual active periods may provide an innovative approach for early detecting and individually tailoring the treatment of circadian disruptions in aging and geriatric healthcare.There is a lack of data from developing countries on the link between physical activity (PA) on health outcomes. This study examines the association between the level of PA and sarcopenia, cardiovascular risk factors (i.e., dyslipidemia, type 2 diabetes (T2D), and cardiovascular diseases), and the health-related quality of life (HRQoL) among elderly people, in community dwellings in Lebanon. In this cross-sectional, observational study, body composition, levels of PA, and the HRQoL of 243 elderly people living in community dwellings, are obtained. The participants are then categorized based on a PA cut-off point of 600 metabolic equivalent task minutes per week (MET-min/week). In our sample, the prevalence of physical inactivity, defined as performing less than 600 MET-min/week, is 51.44% (125/243 participants).They displayed a higher prevalence of sarcopenia (36.0% vs. 18.6%), T2D (39.6% vs. 21.1%), as well as a lower physical (65.67 ± 20.72 vs. 75.08 ± 17.29) and mental (67.58 ± 21.51 vs. see more 76.95 ± 17.16) HRQoL. On the other hand, regression analysis shows that an increased rate of PA to ≥600 MET-min/week is associated with a lower risk of T2D (OR = 0.43, 95% CI 0.22-0.84, p = 0.013) and sarcopenia (OR= 0.40, 95% CI 0.22-0.73, p = 0.003) by 60%, and higher scores of the physical (β = -7.65; -11.87, -3.43, p = 0.0004) and mental (β = -8.47; -13.08, -3.85, p = 0.0004) HRQoL by nearly eight points. Our results show a high prevalence of physical inactivity in Lebanese adults over the age of 60; however, an adequate level of PA among this population seemed to be associated with a lower risk of sarcopenia and T2D, as well as a better HRQoL. However, future longitudinal studies are still needed to clarify if intervention based on increasing levels of PA can determine improvement in these clinical outcomes. If this is shown to be the case, it emphasizes the importance of implementing strategies to increase physical activity within this population.The effects of titanium (Ti) ion-implanted doses on the chemical composition, surface roughness, mechanical properties, as well as tribological properties of 316L austenitic stainless steel are investigated in this paper. The Ti ion implantations were carried out at an energy of 40 kV and at 2 mA for different doses of 3.0 × 1016, 1.0 × 1017, 1.0 × 1018, and 1.7 × 1018 ions/cm2. The results showed that a new phase (Cr2Ti) was detected, and the concentrations of Ti and C increased obviously when the dose exceeded 1.0 × 1017 ions/cm2. The surface roughness can be significantly reduced after Ti ion implantation. The nano-hardness increased from 3.44 to 5.21 GPa at a Ti ion-implanted dose increase up to 1.0 × 1018 ions/cm2. The friction coefficient decreased from 0.78 for un-implanted samples to 0.68 for a sample at the dose of 1.7 × 1018 ions/cm2. The wear rate was slightly improved when the sample implanted Ti ion at a dose of 1.0 × 1018 ions/cm2. Adhesive wear and oxidation wear are the main wear mechanisms, and a slightly abrasive wear is observed during sliding. Oxidation wear was improved significantly as the implantation dose increased.The battle against the Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS) epidemic are still raging in South Africa (SA) despite all the preventive strategies implemented via the five-year strategic plan (2011-2015). The intensity of the AIDS pandemic in SA creates additional challenges for the health workers as they have to deal with an increasing number of people who suffer from this disease. Professional nurses are a critical part of the workforce. The qualitative, explorative, descriptive, and contextual study design was conducted in five public hospitals from each district of Limpopo Province. The purpose of the study was to explore and describe experiences regarding support received by professional nurses while providing care to HIV and AIDS patients in the public hospitals of Limpopo Province. Purposive sampling was employed to select the participants who provided care to HIV and AIDS patients for 24 months or more. The recruitment of participants continued until data saturation was reached at participant number 20. Data were collected through face-to-face individual interviews using a semi-structured guide. Data were analyzed using Tech's qualitative data analysis method. Trustworthiness was measured through credibility, dependability, confirmability, and transferability. Findings Emotional and physical strain due to a shortage of staff, heavy workload, staff turnover, and high absenteeism were experienced by the nurses fulfilling these tasks. Exhaustion, fatigue, increased levels of stress, and lack of training, counselling, debriefing sessions, recognitions, and reward systems were also experienced. Recommendations A program for support of all professional nurses providing care to HIV and AIDS patients should be conceptualized and implemented.
