AbstractAccording to the World Health Organization and other authorities, falls are one of the main causes of accidental injuries among the elderly population. Therefore, it is essential to detect and predict the fall activities of older persons in indoor environments such as homes, nursing, senior residential centers, and care facilities. Due to non-contact and signal confidentiality characteristics, radar equipment is widely used in indoor care, detection, and rescue. This paper proposes an adaptive channel selection algorithm to separate the activity signals from the background using an ultra-wideband radar and to generalize fused features of frequency- and time-domain images which will be sent to a lightweight convolutional neural network to detect and recognize fall activities. The experimental results show that the method is able to distinguish three types of fall activities (i.e., stand to fall, bow to fall, and squat to fall) and obtain a high recognition accuracy up to 95.7%.

Falls have become one of the reasons for death. It is common among the elderly. According to World Health Organization (WHO), 3 out of 10 living alone elderly people of age 65 and more tend to fall. This rate may get higher in the upcoming years. In recent years, the safety of elderly residents alone has received increased attention in a number of countries. The fall detection system based on the wearable sensors has made its debut in response to the early indicator of detecting the fall and the usage of the IoT technology, but it has some drawbacks, including high infiltration, low accuracy, poor reliability. This work describes a fall detection that does not reliant on wearable sensors and is related on machine learning and image analysing in Python. The camera's high-frequency pictures are sent to the network, which uses the Convolutional Neural Network technique to identify the main points of the human. The Support Vector Machine technique uses the data output from the feature extraction to classify the fall. Relatives will be notified via mobile message. Rather than modelling individual activities, we use both motion and context information to recognize activities in a scene. This is based on the notion that actions that are spatially and temporally connected rarely occur alone and might serve as background for one another. We propose a hierarchical representation of action segments and activities using a two-layer random field model. The model allows for the simultaneous integration of motion and a variety of context features at multiple levels, as well as the automatic learning of statistics that represent the patterns of the features.

Abstract Healthy ageing is a public health problem globally. In Europe, the dependency ratio of the elderly is expected to increase by 21.6 per cent to 51.2 per cent in 2070. The World Health Organization (WHO) study on healthy ageing started in 2002 as a concept whereby all people of all ages should be able to live in a healthy, safe and socially inclusive way. The aim of this study is to present preliminary results of the project Identification of Determinants of Healthy Ageing in Italy (IDAGIT) that aimed to collect data on the active and healthy ageing of the Italian population aged over 18 using the conceptual framework of the WHO's ageing model. To link the determinants of the IDAGIT studies to those of the WHO model, we performed a confirmatory factor analysis which reported these variables as significant (in order of factor loading): smoking, cognition score, comorbidity, outdoor built environment, participation, working expertise and income. Considering comorbidity, 83.8 per cent of the sample declared not having any chronic diseases or to have only one, and regarding neurological diseases, only nine people had received a diagnosis of stroke. Regarding gender, the personal determinants and physical and social environments did not result in statistically significant differences, whereas we found statistical differences between the aged groups in all variables analysed. These results provide a first bio-psycho-social perspective on ageing in the Italian population.

RESUMO Objetivo Avaliar, por meio de questionários padronizados, a qualidade de vida de idosos com deficiência auditiva diagnosticada que utilizam ou não a prótese auditiva (AASI) e de idosos sem queixa auditiva. Método Trata-se de um estudo transversal, com amostra não probabilística, distribuída em três grupos divididos da seguinte forma: 30 idosos com perda auditiva diagnosticada e com indicação para uso do aparelho de amplificação sonora individual (AASI), mas que ainda não faziam uso da prótese; 30 idosos com deficiência auditiva que usavam o AASI; e 30 idosos sem queixa auditiva. Os participantes completaram um questionário que investigava dados sociodemográficos e familiares, o Hearing Handicap Inventory for the Elderly Screening Version (HHIE-S) e o World Health Organization Quality of Life - versão breve (WHOQOL-Breve). Além das análises descritivas dos dados, foram realizados testes para comparação dos três grupos, aplicando-se a análise de variância (ANOVA) e o teste post hoc de Bonferroni. Resultados Os três grupos se diferenciaram significativamente em todos os domínios de qualidade de vida. O grupo de idosos com perda auditiva diagnosticada e com indicação para uso do AASI apresentou menores escores que o grupo de idosos com deficiência auditiva que usavam o AASI e que o grupo de referência. O grupo com AASI apresentou os melhores resultados de qualidade de vida. Conclusão A perda auditiva afeta a qualidade de vida do idoso. O uso efetivo da prótese auditiva é benéfico a esta população, melhorando suas condições de vida e saúde.

Criminological concerns with the victimization of the elderly has developed parallel to, and independently of, the elder abuse debate. Criminologists have traditionally been concerned with the commission of acts against the older person in public as opposed to private space. A further hindrance to criminological enquiry is the practice of defining elder abuse in terms of victim needs, rather than of basic human rights. There has been no neat evolutionary process from positive treatment of the elderly, attributed to some golden age in the past to their increasing present victimization rates globally. Elder victimization is a long way from the simplistic notions of “granny battering.” There is general agreement among scholars that older people regularly suffer victimization in private space—in the household and in care institutions. They regularly experience multiple forms of abuse. One can attribute some of these experiences to major social changes as declining family support for older people diminishes and the proportion of young to old decreases. The World Health Organization (WHO) states that as the global population ages, the number of people aged sixty years and older is estimated to reach 1.2 billion worldwide by 2025. More pointedly, the longevity is also inextricably linked to the maltreatment of the global old. In particular, we have seen offenders apprehended in transgressions against the young, women, and ethnic minorities but have yet to see an active criminal justice response concerned with the experience of elder victimization. The discipline’s reluctance to recognize elder victimization is associated with it commonly being labeled as victimization by intimates, and to be understood through the lenses of psychology and psychiatry rather than through a criminal justice model. Care and individual needs of the elderly have been the traditional focus, rather than social justice, reason, and rights. Justice and rights involve choice and free will. Older people are not simply passive recipients of other people’s actions—they resist their victimization and often fight back. This article is a critical exposition of the sources available on elders abused as part of a larger account of the experience of older people worldwide. In particular, the reader is reminded that this article is limited due to publishing word constraints. Therefore, it provides a balanced, limited overview of the major literature and research available in the Western context. More pointedly, the literature cited here is intended to reflect on recent scholarship considered to have the potential of adding to the debate in criminology and elder victimization. Given that the study of elder abuse is still in its infancy in the discipline of criminology, this article is therefore necessarily interdisciplinary.

Background: According to the World Health Organization (WHO), an elderly person is someone who has entered the age of 60 years and above whose percentage tends to increase along with decreasing morbidity of the elderly. Geriatric Neurology itself is the study of a group of neurological diseases in the elderly. Based on 2012 data, the proportion of elderly population in Indonesia is 7.59%. This is accompanied by an increase in the dependency ratio of the productive age population to the non-productive age population. The results of the 2013 Basic Health Research showed an increase in the prevalence of neurological disease in the elderly which was the main cause of death in 15 regencies in 2011. It is to find out the 5 most neurological diseases in the elderly, clinical characteristics and outcomes of geriatric neurology patients treated at the Central Hospital of Sanglah.Methods: It is a retrospective study using no control by looking at medical records in geriatric neurology patients aged 60 years and over who visited the Central Hospital of Sanglah in the March to May 2019 period.Results: A total of 200 patients consisted of 111 men (55.5%) and 89 women (44.5%) who were divided into 5 most geriatric neurology diseases which included 1. ischemic stroke, 2. bleeding stroke, 3. brain tumor, 4. injury head, and 5. epilepsy. The number of deaths was 16, of which 7 cases were caused by sepsis and pneumonia.Conclusions: Stroke, tumors, head injuries and epilepsy are the dominant neurological diseases found. The focus of care and supervision of elderly neurology patients is expected to be further enhanced to prevent side effects that will extend the patient’s treatment period in the hospital which will automatically increase the burden on the hospital itself.

Influenza is a highly contagious viral respiratory disease that affects million of people worldwide each year. Annual vaccination is recommended by the World Health Organization with the goal of reducing influenza severity and limiting transmission through elicitation of antibodies targeting the hemagglutinin (HA) glycoprotein. The antibody response elicited by current seasonal influenza virus vaccines is predominantly strain-specific, but pre-existing influenza virus immunity can greatly impact the serological antibody response to vaccination. However, it remains unclear how B cell memory is shaped by recurrent annual vaccination over the course of multiple seasons, especially in high-risk elderly populations. Here, we systematically profiled the B cell response in young adult (18–34 year old) and elderly (65+ year old) vaccine recipients that received annual split inactivated influenza virus vaccination for 3 consecutive seasons. Specifically, the antibody serological and memory B-cell compartments were profiled for reactivity against current and historical influenza A virus strains. Moreover, multiparametric analysis and antibody landscape profiling revealed a transient increase in strain-specific antibodies in the elderly, but with an impaired recall response of pre-existing memory B-cells, plasmablast (PB) differentiation and long-lasting serological changes. This study thoroughly profiles and compares the immune response to recurrent influenza virus vaccination in young and elderly participants unveiling the pitfalls of current influenza virus vaccines in high-risk populations.

Worldwide, the number of people age 60 and older is expected to grow from nearly 900 million in 2015 to over 1.3 trillion in 2030 (1). Increased age is associated with gradual increases in molecular and cellular damage; impairment of bodily functions; decreased muscle mass and strength; loss of bone density; declining vision, hearing and cognition; multimorbidity; and frailty (2). Frailty has been conceptualized as a physiological syndrome of decreased reserve and resilience, resulting in progressive functional decline, increased vulnerability to many stressors, and an increase in negative health outcomes and dependence (3, 4). It has been recognized by the World Health Organization (2) and the U.S. National Academy of Sciences (5) as a major public health concern among the elderly, although consensus on a definition of frailty remains elusive (6). Nonetheless, research suggests that disability and dependence in the elderly may be preventable by targeting frail and pre-frail older adults (3, 7, 8).

The World Health Organization has declared that the spread of tuberculosis is a global emergency. Despite the implementation of strong tuberculosis-control initiatives by WHO, this highly infectious disease continues to affect all vulnerable populations, including the elderly population. Adverse social factors and poor living conditions also affect the elderly much more than the young. The clinical characteristics of tuberculosis in older adults can be unusual and may be confused with age-related illnesses. Various factors related to old age can also cause complications in the diagnosis, treatment, and disease outcomes for tuberculosis patients. The contributory factors may be poor memory, deafness, mental confusion, or impairment of speech. In addition, therapy for tuberculosis in elderly individuals is challenging because of the increased incidence of adverse drug reactions. Hence, understanding the impact of these substantial aspects will help to overcome the problem of tuberculosis in the elderly population.
