OBJECTIVE Prior trauma history is a reliable and robust risk predictor for PTSD development. Obtaining an accurate measurement of prior trauma history is critical in research of trauma-related outcomes. The Life Events Checklist (LEC) is a widely used self-report measure of trauma history that categorizes events by the proximity to trauma exposure; however, the field has published multiple scoring methods when assessing the LEC. Herein, we propose a novel scoring procedure in which total scores from the LEC are weighted according to the proximity of trauma exposure with "experienced" events weighted most and "learned about" events weighted least. METHOD The utility of this weighted score was assessed in two traumatically-injured civilian samples and compared against previously published scoring methods, including a nonweighted score including all events experienced, witnessed, and learned about, as well as a score consisting of only experienced events. RESULTS Results indicated the standard total score was most reliable, followed by the weighted score. The experienced events score was least reliable, but the best predictor of future PTSD symptoms. CONCLUSIONS One method to balance the predictive strength of experienced events and the excellent reliability of a total LEC score, is to adopt the newly proposed weighted score. Future use of this weighted scoring method can provide a comprehensive estimate of lifetime trauma exposure while still emphasizing the direct proximity of experienced events compared with other degrees of exposure.

The nociceptive network, responsible for transmission of nociceptive signals that generate the pain experience, is not fully developed at birth. Descending serotonergic modulation of spinal nociception, an important part of the pain network, undergoes substantial postnatal maturation and is suggested to be involved in the altered pain response observed in human newborns. This review summarizes preclinical data of the development of descending serotonergic modulation of the spinal nociceptive network across the life span, providing a comprehensive background to understand human newborn pain experience and treatment. Sprouting of descending serotonergic axons, originating from the rostroventral medulla, as well as changes in receptor function and expression take place in the first postnatal weeks of rodents, corresponding to human neonates in early infancy. Descending serotonergic modulation switches from facilitation in early life to bimodal control in adulthood, masking an already functional 5-HT inhibitory system at early ages. Specifically the 5-HT3 and 5-HT7 receptors seem distinctly important for pain facilitation at neonatal and early infancy, while the 5-HT1a, 5-HT1b, and 5-HT2 receptors mediate inhibitory effects at all ages. Analgesic therapy that considers the neurodevelopmental phase is likely to result in a more targeted treatment of neonatal pain and may improve both short- and long-term effects. Impact: The descending serotonergic system undergoes anatomical changes from birth to early infancy, as its sprouts and descending projections increase and the dorsal horn innervation pattern changes.Descending serotonergic modulation from the rostral ventral medulla switches from facilitation in early life via the 5-HT3 and 5-HT7 receptors to bimodal control in adulthood.A functional inhibitory serotonergic system mainly via 5-HT1a, 5-HT1b, and 5-HT2a receptors at the spinal level exists already at the neonatal phase but is masked by descending facilitation.

Purpose: Pediatric blood cancer diagnosis is a stressful experience for families as it can involve urgent treatment that can be life-threatening and require extended hospital stays. Little is known about the experiences of parent caregivers of children with a blood cancer during the diagnosis period and how families' needs may differ in light of the patient's developmental phase in the life span. Methods: We conducted semistructured in-depth interviews with 20 parent caregivers (aged 30-65) of children diagnosed with a blood cancer, recruited through The Leukemia & Lymphoma Society's (LLS) constituency. Interview transcripts were thematically analyzed using the constant comparative method. To elucidate similarities and differences in caregiving experiences, findings were compared across parents with children diagnosed in three developmental periods: infancy-early childhood, age 0-6 (n = 9); pre-early adolescence, aged 9-14 (n = 5); and late adolescence-emerging adulthood, aged 16-27 (n = 6). Results: Across all developmental periods, parents described three similar caregiving experiences during the diagnosis period: being persistent to obtain a diagnosis, attending to the child's quality of life challenges, and attending to their other children's well-being. Among caregivers of younger children, persistence was motivated by parental intuition and challenges included coping with traumatic physical and psychological impacts of treatment procedures. For caregivers of late adolescents-early adults, persistence was motivated by the child's self-assessment and fertility-related concerns emerged. Conclusion: Results illustrate core issues for parent blood cancer caregivers and highlight ways to tailor supportive resources that facilitate good communication practices and shared decision-making to children's distinct developmental needs.

The “no dose is safe” linear no-threshold (LNT) model forms the basis for radiation safety in radiology practice. This model has its origins in observations of germline mutations in fruit flies exposed to X-rays. After World War II, quantitative risk estimates of radiation injury are primarily derived from the atomic bomb survivor Life Span Study. Current understanding of tissue response to radiation has raised doubts about the validity of LNT model at low doses encountered in the practice of diagnostic radiology. This article traces the evolution of basic radiation safety concepts and provides a bird's eye view of the Life Span Study and other studies which throw light on the matter. The arguments for an alternative, threshold, or even hermetic models of dose response are examined. The relevance of these developments to the nuclear power industry is also outlined.

Background: The lifetime risk of lung cancer incidence due to radiation for nonsmokers is overestimated because of the use of the average cancer baseline risk among a mixed population, including smokers. In recent years, the generalized multiplicative (GM)-excess relative risk (ERR) model has been developed in the life span study of atomic bomb survivors to consider the joint effect of radiation and smoking. Based on this background, this paper discusses the issues of radiation risk assessment considering smoking in two parts.Materials and Methods: In Part 1, we proposed a simple method of estimating the baseline risk for nonsmokers using current smoking data. We performed sensitivity analysis on baseline risk estimation to discuss the birth cohort effects. In Part 2, we applied the GM-ERR model for Japanese smokers to calculate lifetime attributable risk (LAR). We also performed a sensitivity analysis using other ERR models (e.g., simple additive (SA)-ERR model).Results and Discussion: In Part 1, the lifetime baseline risk from mixed population including smokers to nonsmokers decreased by 54% (44%–60%) for males and 24% (18%–29%) for females. In Part 2, comparison of LAR between SA- and GM-ERR models showed that if the radiation dose was ≤200 mGy or less, the difference between these ERR models was within the standard deviation of LAR due to the uncertainty of smoking information.Conclusion: The use of mixed population for baseline risk assessment overestimates the risk for lung cancer due to low-dose radiation exposure in Japanese males.

“Royal Jelly” is a viscous material which is secreted by the cephalic gland of the “worker bee.” This is the key component of the “queen bee’s” diet, rendering it with longer life span compared to worker bees.“Royal Jelly” possess various pharmacological properties. These includes antioxidant, neurotropic, anti-inflammatory, immunomodulatory and antibiotic, anti-aging, antihypertensive properties. This article summarizes biological properties, composition, criteria of quality evaluation of “Royal Jelly”and published studies on the efficacy of “Royal Jelly” as a “wound healing agent” , as a component of mouth wash used in treatment of oral mucositis, periodontal diseases, as a storage media and as a pulp capping agent.“Royal Jelly” can emerge as a viable alternative to conventional synthetic agents, which may avoid usual drawbacks of synthetic medicaments.

Along with rapid economic development and aged tendency of populations, women should not only pursue the extension of life span, but also enjoy a healthy life in the postmenopausal and elder stage. It is imperative to conduct menopause management amongst the menopausal women. Healthy lifestyle is the primary content of menopause management. The effectiveness of menopausal hormone therapy (MHT) is well established, but risks associated with MHT remain complex issues. This article reviews the development and current status of menopause management, summarizes the controversial issues about MHT, and provides an outlook for future research of menopause management.

The main goal of this study is to achieve the extended operating life of the rotary regenerative air pre-heater (Ljungström) of Bandar Abbas power plant by modifying operational parameters by decreasing the corrosion. To achieve this goal, a three-dimensional CFD simulation of the Ljungström is carried out, utilizing the thermal non-equilibrium porous media model. Temperatures are validated against measured data from the power plant with a maximum relative error of 5.54% on the Celsius scale, and mass flow rates are validated with a maximum relative error of −5.25%. The effect of the Ljungström key parameters including the rotational speed, cold layer material, inlet air/flue gas temperature, and mass flow rate, are analyzed in presence of leakages and neglecting it, using porous media approach. The leakage effect is investigated considering radial and axial/peripheral clearances. Finally, a simulation is performed by applying feasible improved parameters extracted from the above analyses considering the effect of all parameters together in presence of leakages, which shows a 6.14% improvement in the Ljungström effectiveness, reducing the total leakage to about one-third of the actual model and eliminating any corrosion.

Women around the world live longer than men. The question of why this is happening is very interesting, but still unresolved in gerontology. There are a number of proposals to explain the mechanisms underlying this phenomenon, but there are no clearly confirmed or refuted ones among them. This is probably due to the fact that it is extremely difficult to organize the testing of such hypotheses for Homo sapiens, and the available data on animals are often contradictory and their results cannot be fully transferred to humans. In the article, we tried to identify one of the possible mechanisms leading to sex differences in life expectancy in the human population. The depressing effect of testosterone on the immune system of women is much weaker than on the immune system of men. The concentration of testosterone in the blood of men is 10–18 times higher than that of women, and, after the onset of menopause, the already low concentration of testosterone in women drops by another 25–50%. The immune system of men weakens with age to a greater extent, which leads to an increased incidence of infectious, oncological, and other immune-dependent pathologies, which just reduces the minimal, middle, and maximum life span of men compared with women.

People with disabilities are more likely to be hospitalized and use healthcare services relative to people without disabilities. They also report experiencing negative experiences interacting with health care providers during these encounters placing them at risk for preventable adverse medical events, poor quality of life, and dependence on others. Fortunately, providers and people with communication disabilities can take steps to improve these interactions by personalizing and implementing communication supports to empower people with communication disabilities to actively participate in these interactions and improve outcomes. The purpose of this article is to describe strategies that health care providers can use to develop and implement personalized communication supports for children and adults with communication disorders during health care interactions. Additional strategies are provided to guide people with disabilities as well as their community/school providers and families to prepare for health care interactions. Case examples are provided to illustrate use of these strategies in acute care, inpatient rehabilitation, and outpatient settings. The use of emerging training tools (e.g., video visual scene displays) and AAC partner training formats (e.g., just-in-time training) are also presented as future directions to expedite learning and implementation of communication supports in fast-paced and time-limited health care interactions.

Eating outside the three main meals - in other words, snacking - is a part of the dietary pattern of individuals in all stages of life. The quality and pattern of snacking have an impact on health during the life span. Thus, the aim of this review was to evaluate various patterns and health outcomes of the snacking habits of different demographical groups, from children to the elderly, throughout their life span. We discuss the snacking pattern among children and adolescents, which is characterized by consuming high energy foods with low nutrient value, and which is associated with increased risk of obesity. During university years, study stress and lack of time were obstacles to a healthy dietary pattern involving nutritious snacks, although awareness of the importance of healthy snacks was higher in this group than among younger age groups. Employment status and skipping regular meals were important factors affecting snacking quality and patterns in adulthood. Unhealthy snacks, high in energy, sugar, and salt and low in nutrients, were demonstrated to have a negative impact on individuals' health, such as oral health, blood pressure, obesity, and diabetes. In conclusion, encouraging individuals to consume healthy snacks that are high in nutrients through education to help them plan for their snacks is important to enhance health and reduce disease risk.

We perform a sensitivity study on the ventilation effect of large hydrometeors, namely, raindrops, snow aggregates, and hail in a cloud-resolving model. The ventilation effect could accelerate the heat and mass transfer rates between vapor and falling hydrometeors. It causes the falling hydrometeors to grow (in a supersaturated environment) and dissipate (in a subsaturated environment) faster than the stationary ones. The parameterizations of the ventilation effect on hydrometeors in a cloud model is critical as it could dramatically alter the structure and the lifespan of the simulated storm. Enhancing the ventilation coefficients of falling hydrometeors leads to a longer-lived storm featured by apparent storm splitting. The temporal evolution of hail density fluctuates greater than the default case (the control case) indicating both stronger deposition and sublimation in hail microphysical processes. However, both rainfall and hailfall become less intense than the control run. In contrast, reducing the ventilation effect causes moderate evaporation of raindrops as they fall through subsaturated air. Consequently, the concentration and precipitation rate of raindrops increase near the surface. Strong downdraft accompanying the heavy rainfall cuts off the low-level inflow of unstable moist air into the storm and results in early dissipation of the storm.

Background and Aims: Physical health is an important aspect of the health of any society and one of the most basic needs of human life. The present study aimed to investigate the effect of body mass index and level of physical activity on motor competence in women within the age range of 8-85 years in Tehran, Iran. Materials and Methods: The present cross-sectional study was performed on 323 women aged 8-85 years who were divided into five groups, namely children, adolescents, young women, adults, and the elderly. The participants were selected using the convenience sampling method, and the required data were collected using a weight gauge, a height gauge, the short form of the International Physical Activity Questionnaire, and a motor competence test. The collected data were analyzed using multivariate one-factor analysis of variance and Bonferroni test. Results: The results of multivariate one-factor analysis of variance showed that the body mass index had no significant effect on motor competence (P

We developed and validated a synthetic cohort approach to examine numbers of cardiovascular risk factors (CRFs) and adverse clinical events, including incident cardiovascular disease and all-cause mortality, across the life span from ages 20 years to 90 years. The current analysis included 40,875 participants from 7 large, population-based longitudinal epidemiologic studies (1948–2016). On the basis of a joint multilevel imputation model, we multiply imputed each participant’s life-span numbers of CRFs and events using available records. To validate the imputed values, we partially removed the observed data and then compared the imputed and observed values. The complete life-span synthetic data set reflected the original observed data trends well. In our validation sample, the distributions of imputed CRFs and events were close to the observed distributions but with less variability. Bland-Altman plots indicated that there was a slightly negative trend in general, and the agreement bias was relatively small for the continuous CRFs. The hypothetical linear regression model suggested that the relationships between the CRFs and events were preserved in the imputed data set. This approach generated valid estimates of CRFs and events across the life span for African-American and White participants. The synthetic cohort may be sufficiently accurate to be useful in assessing the origins and timing of accumulating cardiovascular risk that can inform efforts to avoid cardiovascular disease development.

Much like other living organisms, yeast cells have a limited life span, in terms of both the maximal length of time a cell can stay alive (chronological life span) and the maximal number of cell divisions it can undergo (replicative life span). Over the past years, intensive research revealed that the life span of yeast depends on both the genetic background of the cells and environmental factors. Specifically, the presence of stress factors, reactive oxygen species, and the availability of nutrients profoundly impact life span, and signaling cascades involved in the response to these factors, including the target of rapamycin (TOR) and cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) pathways, play a central role. Interestingly, yeast life span also has direct implications for its use in industrial processes. In beer brewing, for example, the inoculation of finished beer with live yeast cells, a process called “bottle conditioning” helps improve the product's shelf life by clearing undesirable carbonyl compounds such as furfural and 2‐methylpropanal that cause staling. However, this effect depends on the reductive metabolism of living cells and is thus inherently limited by the cells' chronological life span. Here, we review the mechanisms underlying chronological life span in yeast. We also discuss how this insight connects to industrial observations and ultimately opens new routes towards superior industrial yeasts that can help improve a product's shelf life and thus contribute to a more sustainable industry., This review article outlines the mechanisms underlying chronological life span in yeast, with a focus on nutrient signaling pathways and strain‐to‐strain differences in chronological life span. It also connects these insights to industrial observations, which opens new routes towards the generation of superior industrial yeasts.

The learning effectiveness of video lectures has been extensively studied by the scientific community, but research on their cost-effectiveness and sustainable production is still very scarce. To shed light on these aspects, this study has measured the useful life span and cost-effectiveness of a large catalog of video lectures produced for undergraduate courses at a Spanish university. A Kaplan–Meier survival analysis has been performed to identify factors linked to video longevity. The analysis accounted for variables such as the video production style (screencast, slideshow, chalk and talk, talking head, and on-location film) and others such as the instructional purpose and field of knowledge. The teachers involved in video production and integration have been surveyed to discover causes of video obsolescence. In addition, using life span and production cost data, the cost-effectiveness of each production style over time was estimated. The results suggest that production style affects video longevity, and in particular, dynamic visuals are more related to longer life spans compared with static contents. Screencast stands out as the most cost-effective production style, having the best ratio of life span to production effort. Some practical suggestions are provided for producing video lectures with higher longevity expectations.

The lifetime of high voltage equipment is very dependent on the condition of insulation, poor insulation means the life span of high voltage equipment is getting shorter. Partial Discharge is one of the causes of deterioration of high voltage equipment insulation. The ability to know the phenomenon of partial discharge in equipment becomes very important and adds value to the maintenance of high voltage equipment. Many explanations regarding partial discharge, partial discharge is the lack of uniformity of the electric field in the isolation or dielectric media which will result in the phenomenon of Partial Discharge where this will lead to the failure of the isolation media. Partial Discharge that occurs continuously can cause damage (breakdown) on a high voltage equipment. Therefore, before a high voltage device is used, Partial Discharge detection is necessary. Partial Discharge Detection can use the Partial Discharge measurement circuit. In testing partial discharges can be tested using a sensor with various circuits including High Frequency Current Transformers (HFCT) so that this research will discuss one part of the Partial Discharge measurement circuit, the HFCT detector. Hopefully, the HFCT detector can be further developed and can be used for better partial discharge detection.

Cracks considerably reduce the life span of pavement surfaces. Currently, there is a need for the development of robust automated distress evaluation systems that comprise a low-cost crack detection method for performing fast and cost-effective roadway health monitoring practices. Most of the current methods are costly and have labor-intensive learning processes, so they are not suitable for small local-level projects with limited resources or are only usable for specific pavement types.This paper proposes a new method that uses an adapted version of the weighted neighborhood pixels segmentation algorithm to detect cracks in 2-D pavement images. The method uses the Gaussian cumulative density function (CDF) as the adaptive threshold to overcome the drawback of fixed thresholds in noisy environments. The proposed algorithm was tested on 300 images containing a wide range of noise representative of various pavement noise conditions. The method proved to be time and cost-efficient as it took less than 3.15 s per 320 × 480 pixels image for a Xeon (R) 3.70 GHz CPU processor to generate the detection results. This makes the proposed method a perfect choice for county-level pavement maintenance projects requiring cost-effective pavement crack detection systems. The validation results were promising for the detection of medium to severe-level cracks (precision = 79.21%, recall = 89.18%, and F1score = 83.90%).

Historically, rheumatic diseases have not received much attention in Africa, particularly in sub-Saharan Africa, possibly owing to a focus on the overwhelming incidence of infectious diseases and the decreased life span of the general population in this region. Global attention and support, together with better health policies and planning, have improved outcomes for many infectious diseases; thus, increasing attention is being turned to chronic non-communicable diseases. Rheumatic diseases were previously considered to be rare among Africans but there is now a growing interest in these conditions, particularly as the number of rheumatologists on the continent increases. This interest has resulted in a growing number of publications from Africa on the more commonly encountered rheumatic diseases, as well as case reports of rare diseases. Despite the limited amount of available data, some aspects of the epidemiology, genetics and clinical and laboratory features of rheumatic diseases in African populations are known, as is some detail on the use of therapeutics. Similarities and differences in these conditions can be seen across the multi-ethnic and genetically diverse African continent, and it is hoped that increased awareness of rheumatic diseases in Africa will lead to earlier diagnosis and better outcomes for patients., The prevalence of rheumatic diseases is increasing in African countries, leading to an increased need for specialist rheumatologists and disease-modifying drugs. In this Review, the authors outline what is currently known about the state of rheumatic diseases in Africa., Key points In the past, there has been an emphasis on communicable diseases in Africa, but attention has now shifted towards non-communicable diseases such as rheumatic diseases. Common rheumatic diseases are seen in Africa and are both comparable and different from presentations seen outside of Africa. Diverse genetic and environmental factors affect the presentation of common rheumatic diseases among different African nations. A shortage of appropriately trained staff, laboratory testing capacity and effective medications exists across the whole continent. Advocacy and research are needed to increase awareness of the risk factors, presentations and management of rheumatic diseases in Africa. Specialized treatment guidelines are needed for resource-poor countries in Africa.

OBJECTIVES: To employ a novel analytic approach to quantify psychological resilience to physical health difficulties and identify factors associated with greater resilience in older U.S. veterans. METHODS: Data from a nationally representative sample of older U.S. military veterans (n=3,001), who participated in the National Health and Resilience in Veterans Study were analyzed to develop the Psychological Resilience Against Physical Difficulties Index (PRAPDI). Multiple regression and relative importance analyses were conducted to identify factors associated with greater PRAPDI scores. RESULTS: Secure attachment style [17.3% relative variance explained (RVE)], mindfulness [16.6% RVE], and purpose in life [15.0% RVE] emerged as the strongest correlates of PRAPDI scores. CONCLUSIONS: Intervention strategies aimed at fostering mindfulness, attachment security, and purpose in life may help promote psychological resilience to the challenges of physical aging in older veterans.

Summary Background & aims Empirical analyses of the data available around the word concluded that women have longer life span now, when compared to the men. Available literature unfortunately could not offer full answers to this observation. The “entropic age” concept suggests that ageing related changes in the body, such as loss of molecular functions and overwhelming of the maintenance systems, may be explained in terms of entropy generation. Methods Telomere-length regulated entropic assessment based on metabolic activity with four different diets carried out. Results Estimates of the life expectancy of the women on all of these diets is longer than those of the men. Faster shortening of the telomere lengths in men was the major reason of the shorter life expectancy. The highest and the lowest life expectancy for women were estimated with Mediterranean and the vegetarian diets, respectively; men were estimated to have the longest life span with the vegetarian diet and the shortest life span with the ketogenic diet. Conclusions A higher rate of metabolism causes higher entropy generation and hints correlations that can be helpful in future ageing research. Faster shortening of the telomere lengths in men was the major reason of the estimation of the shorter life span for men.

Recent studies on thermal effects reported a significant rise in global temperature associated with global warming. To counteract this effect in building sectors, the need to keep the building interior at a temperature compatible to comfortable conditions has become a major concern to the engineers. The basic solution is to air condition the building which is not effective on an economic scale considering the life span of the building. So, this necessitates the need for a material to be placed inside the building components during construction stage which can absorb the heat from the environment. Phase change materials (PCM) are materials which absorb and release thermal energy due to increase and decrease in temperature. But this PCM cannot exist as such inside the building components and requires encapsulation. This paper reports the details of a PCM which is encapsulated using suspension polymerization technique and incorporated in cement mortar wall panels. The core material was selected considering the economy and the local ambient temperature. Strength and thermal properties were carried out in the wall panel and showed improved behaviour in thermal resistance compared to the control specimen.

A hopeless tooth from a periodontal point of view, with severe bone resorption, mobility and abnormal tooth migration, is often extracted. In advanced cases, function and esthetics are impaired, and an interdisciplinary treatment is requested. Retaining or not these teeth is based on clinician judgment. A growing body of evidence claims that prognosis has great potential to be improved in a motivated patient with good oral hygiene and regular maintenance. This case report aims to present a periodontal regenerative technique combining enamel matrix protein derivatives and a particulated xenograft to treat intraosseous defects caused by periodontitis. The patient healed uneventfully, and no complications were recorded after the surgical procedure. To correct abnormal tooth migration and improve function and esthetics, orthodontic treatment was instituted. Tooth prognosis improved from hopeless to questionable. This approach extended the life span of a compromised tooth, improving periodontal support and decreasing tooth mobility. This could be an alternative to extraction and implant.

Photovoltaic installations are becoming more prevalent globally having expected life span of 20–25 years & optimization of generated power is very vital. Power generated by PV modules is associated with various factors like environmental, climatic & inherent components. Researchers have observed up to 20% reduction in generation by adverse effects of dust, dirt, pollution, sea salt and bird droppings on the PV module. An authentic cleaning solution for PV system is suggested in this paper. Experiments using robots and cleaning mechanisms have been observed over the years however the key barriers for such solutions are costing, viability and complexity. Our study shows that the proposed design and mechanism will eliminate complexity by giving viable solution and reducing the payback period of PV system by 1.3 years.

Stroke, and neurodegenerative diseases represents, a major and rapidly growing burden of mortality and morbidity. The risk factors for stroke starts very early in life. Similarly, the changes of neurodegenerative diseases starts decades earlier than the clinical manifestations. Primordial prevention is necessary to prevent the establishment of risk factors to keep the population disease free. This will help to not only increase the life span, but also to prolong the health span.

With an ever-increasing number of revisions, the surgeons will be faced with the dilemma of choosing the right implant for the revision knee. The soft tissue viability governs the choice of an implant at the time of revision. The selection ranges from the cruciate-retaining to the rotating/fixed hinge implants. The surgeon needs to plan preoperatively, but usually, the final decisions are made intraoperative. As determining the amount of constraint necessary can be challenging, we have tried to lay down a few pointers, which would help to make that choice. The posterior stabilized implants can manage most revision knees; in certain situations where they cannot accommodate the flexion-extension gap imbalance, a varus-valgus constrained implant should be used. The rotating hinge implants are used for severe instabilities or loss of soft tissue or bone around the knee. The use of a higher constraint implant has its consequences like reduced life span and reduced function. Thus it is crucial to use the least amount of constraint as necessary – however, as much as required.

Aging is associated with functional and metabolic decline and is a risk factor for all noncommunicable diseases. Even though mice are routinely used for modeling human aging and aging-related conditions, no comprehensive assessment to date has been conducted on normative mouse aging. To address this gap, the Study of Longitudinal Aging in Mice (SLAM) was designed and implemented by the National Institute on Aging (NIA/NIH) as the mouse counterpart to the Baltimore Longitudinal Study of Aging (BLSA). In this manuscript, we describe the premise, study design, methodologies, and technologies currently employed in SLAM. We also discuss current and future study directions. In this large population mouse study, inbred C57BL/6J and outbred UM-HET3 mice of both sexes are longitudinally evaluated for functional, phenotypic, and biological health, and collection of biospecimens is conducted throughout their life span. Within the longitudinal cohorts, a cross-sectional arm of the study has also been implemented for the well-controlled collection of tissues to generate a biorepository. SLAM and studies stemming from SLAM seek to identify and characterize phenotypic and biological predictors of mouse aging and age-associated conditions, examine the degrees of functional and biomolecular variability that occur within inbred and genetically heterogeneous mouse populations with age, and assess whether these changes are consistent with alterations observed in human aging in BLSA. The findings from these studies will be critical for evaluating the utility of mouse models for studying different aspects of aging, both in terms of interpreting prior findings and designing and implementing future studies.

Implementation of Healthy People 2030 will by strengthened by engaging users from many sectors and ensuring the effective use and alignment of resources. Promoting the nation's health and well-being is a shared responsibility—at the national, state, territorial, tribal, and community levels. It requires involving the public, private, and not-for-profit sectors.

Quality of Life (QOL) and Health-Related Quality of Life (HRQOL) are important concepts across the life span for those with spina bifida (SB). This article discusses the SB Quality of Life Healthcare Guidelines from the 2018 Spina Bifida Association’s Fourth Edition of the Guidelines for the Care of People with Spina Bifida. The focus of these QOL Guidelines was to summarize the evidence and expert opinions on how to mitigate factors that negatively impact QOL/HRQOL or enhance the factors positively related to QOL/HRQOL, the measurement of QOL/HRQOL and the gaps that need to be addressed in future research.

PurposeMore than 460 million people are impacted by disabling hearing loss worldwide. Hearing loss has negative impacts across the life span and varies by individual. Specifically, in children, hearing loss has been shown to affect learning outcomes, behavioral and cognitive growth, and psychosocial development. In adults, hearing loss has been shown to affect quality of life, social isolation, depression, and anxiety. The purpose of this review is to advance the understanding of the latest research in the development of new treatments of hearing loss, including gene therapy, stem cell therapy, and pharmacotherapies. We address the use of animals to model human hearing loss and the importance of animals in previous discoveries and developing new therapies. We highlight the importance of early identification for better speech and developmental outcomes specifically in pediatric individuals. Lastly, we review new possibilities in the prevention of hearing loss and the path to translation into practice.ConclusionsResearch and development of new therapies to treat hearing loss is an ever growing field with many notable successes. However, clinical translation still poses many challenges. Many discoveries related to gene therapy, stem cell therapy, and pharmacotherapy are in the early phases of clinical trials and hold promise. This review empowers audiologists to be aware of these most recent developments and be conscious of the evolving future landscape of treatment and management of hearing loss.

Background: Statins are progressively accepted as being associated with reduced mortality. However, few real-world statin studies have been conducted on statin use in older people and especially the most frail, that is, the nursing home residents. Objective: The aim of this study was to evaluate the impact of statin intake in nursing home residents on all-cause mortality. Method: This is a cross-sectional study of 1,094 older people residing in 6 nursing homes in Flanders (Belgium) between March 1, 2020 and May 30, 2020. We considered all residents who were taking statins for at least 5 days as statin users. All-cause mortality during the 3 months of data collection was the primary outcome. Propensity score overlap-weighted logistic regression models were applied with age, sex, functional status, diabetes, and cardiac failure/ischemia as potential confounders. Results: 185 out of 1,094 residents were on statin therapy (17%). The statin intake was associated with decreased all-cause mortality: 4% absolute risk reduction; adjusted odds ratio 0.50; CI 0.31–0.81, p = 0.005. Conclusions: The statin intake was associated with decreased all-cause mortality in older people residing in nursing homes. More in-depth studies investigating the potential geroprotector effect of statins in this population are needed.

Over the last decades, joint arthroplasty has become a successful treatment for joint disease. Nowadays, with a growing demand and increasingly younger and active patients accepting these approaches, orthopedic surgeons are seeking implants with improved mechanical behavior and longer life span. However, aseptic loosening as a result of wear debris from implants is considered to be the main cause of long-term implant failure. Previous studies have neatly illustrated the role of micrometric wear particles in the pathological mechanisms underlying aseptic loosening. Recent osteoimmunologic insights into aseptic loosening highlight the important and heretofore underrepresented contribution of nanometric orthopedic wear particles. The present review updates the characteristics of metallic and ceramic nanoparticles generated after prosthesis implantation and summarizes the current understanding of their hazardous effects on peri-prosthetic cells.

The prevalence of orofacial pain is on the rise and especially in women, thus indicating an increasing gender difference in orofacial pain., Although a fluctuating pattern of orofacial pain across the life span has been proposed, data on its natural course are lacking. The longitudinal course of orofacial pain in the general population was evaluated using data from routine dental check-ups at all Public Dental Health services in Västerbotten, Sweden. In a large population sample, 2 screening questions were used to identify individuals with pain once a week or more in the orofacial area. Incidence and longitudinal course of orofacial pain were evaluated using annual data for 2010 to 2017. To evaluate predictors for orofacial pain remaining over time, individuals who reported pain on at least 2 consecutive dental check-ups were considered persistent. A generalized estimating equation model was used to analyze the prevalence, accounting for repeated observations on the same individuals. In total, 180,308 individuals (equal gender distribution) were examined in 525,707 dental check-ups. More women than men reported orofacial pain (odds ratio 2.58, 95% confidence interval [CI] 2.48-2.68), and there was a significant increase in the prevalence of reported pain from 2010 to 2017 in both women and men. Longitudinal data for 135,800 individuals were available for incidence analysis. Women were at higher risk of both developing orofacial pain (incidence rate ratio 2.37; 95% CI 2.25-2.50) and reporting pain in consecutive check-ups (incidence rate ratio 2.56; 95% CI 2.29-2.87). In the northern Swedish population studied, the prevalence of orofacial pain increases over time and more so in women, thus indicating increasing differences in gender for orofacial pain.

The study was aimed to investigate the potential benefits of the Consciousness Energy Healing Treatment (the Trivedi Effect®) per se and Biofield Energy Healing treated novel test formulation in male Sprague Dawley rats for their antiaging activity by monitoring aging biomarkers such as brain-derived neurotrophic factor (BDNF), silent information regulator-1 (SIRT-1), and klotho protein. The test formulation was distributed into two parts. First part did not provide any Biofield Energy Treatment was denoted as the untreated sample, however the second part was received Biofield Energy Healing Treatment by a renowned Biofield Energy Healer, Mr. Mahendra Kumar Trivedi and defined as the Biofield Energy Treated sample. In this experiment, nine groups (n=10) were assigned, in which four were preventive maintenance groups. Among them, three groups of animals were also received Biofield Energy Healing Treatment per se (at day -15). BDNF was significantly increased by 25.83%, 19.35%, and 14.67% in the Biofield Energy Treated test formulation (G5), Biofield Energy Treatment per se at day -15 (G6), and Biofield Energy Treatment per se to animals plus Biofield Treated test formulation from day -15 (G8), respectively as compared to the disease control (G2) group. Moreover, expression of SIRT-1 protein was increased by 14.63% in the G5 group than the untreated test formulation (G4) group. Additionally, SIRT-1 activity was increased by 39.7%, 32.5%, 15.9%, and 136% in the G6, Biofield Energy Treated test formulation at day -15 (G7), G8, and Biofield Treatment per se (day -15) to animals plus untreated test formulation (G9) groups, respectively than the G4 group, while it was increased by 57.3% in the G9 group as compared to the G2 group. Besides, Klotho protein in kidney homogenate was significantly increased by 16.67% in the G5 group as compared to the G2 group. Altogether, the results showed a significant improvement of longevity mediators and antiaging biomarkers in the preventive maintenance groups. Therefore, results envisaged the significant slowdown of aging-related disorders and other complications in the preventive Biofield Energy Treatment group per se and/or Biofield Energy Treated Test formulation groups (viz. G6, G7, G8, and G9) comparatively with the disease control group and could be utilized against various aging-related disorders like Alzheimer's disease, hypertension, osteoporosis, cataracts, type 2 diabetes, cancer, etc. along with it could be used to extend the life-span, stress and immune-related disorders.

Purpose Individuals with dysphagia across the age continuum may require dietary modifications of fluids and foods for safe and adequate oral intake. Considerations of this frontline intervention are presented in this clinical forum dedicated to the discussion of dysphagia. Method This clinical focus article reviews the technical challenges of providing modified fluids and foods across the life span as well as the literature specific to its origins, efficacy, challenges and solutions to standardization, and the methods for ensuring quality service delivery. Conclusion Dietary modification is an often-used method of dysphagia management that presents unique challenges to the clinician for successful application. Speech-language pathologists in clinical practice across all settings must remain dedicated to evidence-based practice as they navigate service delivery of this strategy to individuals with dysphagia across the life span.

Purpose This clinical focus article considers the roles of the clinical swallow examination (CSE) as a clinically meaningful assessment method used in both adult and pediatric populations. Method This clinical focus article explores the utility of the CSE across the life span. Specifically, components, reliability, standardized assessments, and limitations of the CSE within the adult and pediatric populations are highlighted. Conclusions The CSE remains a crucial assessment tool for the speech-language pathologist. The experienced clinician can make important judgments regarding patient safety and function. If the CSE is conducted mindfully and methodically, findings can help chart the course of care for individuals needing additional assessment and possibly intervention.

Demand to meet the needs of a rapidly aging population is high. Students outside of gerontology programs, however, remain resistant to enrolling in aging coursework, which are often electives within or outside their degree programs. A life-span development course, however, is likely to be a requirement in many disciplines. In a multigenerational workforce spanning five generations and with intergenerational conflict making media headlines, students must understand how to navigate age-diverse climates. We advocate that a course in life-span development can serve as both a recruitment tool for driving interest in aging-related careers and an access point for preparing students to enter a sometimes contentious, multigenerational workforce. We illustrate how knowledge of developmental influences across the lifespan may lead to a better understanding of individual similarities and differences in developmental experiences, fostering intergenerational cohesion throughout one’s career.

Silicone wristbands are promising passive samplers to support epidemiological studies in characterizing exposure to organic contaminants; however, investigating associated health risks remains challenging because of the latency period for many chronic diseases that take years to manifest. Dogs provide valuable insights as sentinels for exposure-related human disease because they share similar exposures in the home, have shorter life spans, share many clinical/biological features, and have closely related genomes. Here, we evaluated exposures among pet dogs and their owners using silicone dog tags and wristbands to determine if contaminant levels were correlated with validated exposure biomarkers. Significant correlations between measures on dog tags and wristbands were observed (rs = 0.38-0.90; p < 0.05). Correlations with their respective urinary biomarkers were stronger in dog tags compared to that in human wristbands (rs = 0.50-0.71; p < 0.01) for several organophosphate esters. This supports the value of using silicone bands with dogs to investigate health impacts on humans from shared exposures.

Objective To assess the epidemiological and toxicological profile of all suicide victims in 2017 in Rio Grande do Sul, Brazil. Methods The victims were classified by gender, age, parental absence, city, suicide form, death context, and toxicological results, using the police occurrences and the reports issued by the Instituto-Geral de Perícias do RS. Multiple correspondence analysis and the Cochran-Mantel-Haenszel X 2 test were used to evaluate associations between the parameters studied. Results There were 1,284 suicides (11.3 cases/100,000 inhabitants) in RS in 2017, 80% of which were men and 46% were young and old. Porto Alegre had the highest number of victims and the region of the Vale do Rio Pardo, the highest rate (20.8 cases/100,000 inhabitants). The hanging was the most used medium and the depression, the most mentioned context in the occurrences. The presence of ethanol was observed in 30% of the samples analyzed, with an adult male profile associated with the presence of other psychotropic substances, whose class was most frequently detected with anxiolytics. The nitrite was the most detected poison among the samples sent for this purpose. There was an association between parental absence and young people, between suicidal intoxication method and women and among young people and the presence of illicit compounds. Conclusion Mortality due to suicide continues to increase in RS, which, historically, has the highest Brazilian index. The information obtained in this study supports new research, promoting awareness raising, guidance to health services and the elaboration of more preventive public policies.
