Level of physical activity and anthropometric characteristics in old age—results from a national health survey

Advanced age is associated with degenerative changes in body composition. There is evidence suggesting that changes may vary upon differences in lifestyle, environment, or gender. Physical activity engagement is considered an important component of lifestyle definition. There are suggestions that engaging in physical activity might alleviate degenerative body compositional changes. The objective is to assess the relationship between adherence to recommended guidelines of physical activity and anthropometric parameters in Israeli older adults. Anthropometric measures, including height, weight, and waist circumference, were taken, and BMI was calculated, from a random sample of 1,663 elderly adults (799 men and 864 women), aged 74.31 (±6.05) years old. Participants reported their physical activity habits and, based on official guidelines recommendations, they were divided into sufficiently active, insufficiently active, and inactive groups. One-way ANOVA (level of physical activity) for both genders was conducted for each anthropometric variable. In both genders, an association between level of physical activity and weight, waist circumference, and BMI was found, with lower values among the sufficiently active. In addition, a relationship between level of physical activity and height was indicated among women, implying that the more active women were taller than the less active. In addition to the already known health benefits of physical activity in old age, it is possible that adherence to recommended guidelines of physical activity is associated with favorable anthropometric characteristics.     

Testosterone metabolism,dose–response relationships and receptor polymorphisms: selected pharmacological/toxicological considerations on benefits versus risks of testosterone therapy in men

In this review selected toxicological problems related to testosterone therapy in hypogonadal men are discussed. Applying ‘classical’ pharmacological/toxicological findings (e.g. animal studies on short- and long-term toxicity) to clinical situations is not very helpful. Molecular biological knowledge and especially evaluation of epidemiological studies, as well as intervention studies, on testosterone therapy in hypogonadal men are more useful. Potential risks include overdosage for lifestyle reasons, e.g. excessive muscle building and reduction of visceral obesity, when erythrocytosis occurs concomitantly. Modern galenic formulations of testosterone administration (e.g. transdermal gel, suitable testosterone esters for intramuscular application and newer oral preparations) avoid supraphysiological serum concentrations, therefore significantly reducing the toxicological risk. A hypothetical model of the toxicological risks of testosterone therapy is given that is based on the influence of testosterone metabolism (aromatization vs. reduction) of the respective parameter/target chosen. Finally, the great influence of polymorphisms of the androgen receptor on the assessment of toxicological risk and on the individualization of androgen therapy is shown. Already existing national, continental and international guidelines or recommendations for the testosterone therapy should be harmonized.     

Outcomes in the sociology of mental health and illness: where have we been and where are we going?

Sociologists of mental health and illness have traditionally used outcome measures that they have obtained from other disciplines, especially psychiatry and psychology. These include official statistics, symptom scales, and diagnostic measures. Answers to the central sociological question of how social arrangements affect mental health might require the development of explicitly sociological outcome measures. This introduction provides an overview of several issues that arise in grappling with this question. These include whether symptom scales or diagnoses best capture the mental health consequences of social arrangements; when single or multiple outcomes are necessary to compare the consequences of social arrangements across different groups; if sociologists should explore the positive as well as the negative consequences of social forces; and when sociological attention should be directed toward social-level as well as individual-level outcomes. The papers in this symposium that follow provide more detailed analyses of each of these issues.     

A public health crisis in the university: Impact of crisis response strategies on universities’ transparency and post-crisis relationships during COVID 19 pandemic

During the COVID 19 pandemic, one of the most critical tasks of the university was to effectively communicate with students, faculty, and staff members. This study aims to explore perceived universities’ crisis response messages during the pandemic and examine the effectiveness of each response strategy on public relations outcomes. A survey with 346 university students in the U.S., results showed how defensive and accommodative response strategies differently affected PR outcomes. Accommodative strategies generated higher OPR and greater perceived transparency efforts among students, while several defensive strategies affected students’ negative evaluations on post-crisis OPR and perceived transparency of their universities. Such results revealed valuable insights that make significant contributions to theory and practices in university crisis communication and management, especially when dealing with public health crises that are seen as external locus of control.     

Parental responsibilities: Reformulating the paradigm for parent–child relationships Part 2: Who has responsibilities to children and what are these responsibilities?

This is the second part of an article, Part 1 of which proposes the paradigm of parental responsibilities to replace the discourse of rights, custody, and visitation. This Part describes the scope of parental responsibilities; who, alongside or instead of the biological parents, may have parental responsibilities vis-à-vis the child; the roles of grandparents and members of the extended family, and partners of parents, are described. The principal categories of parenting tasks are described in detail. I also show how the concept of parental responsibilities is essential for properly dealing with children in need of protection, and how the paradigm applies to courts that deal with proceedings involving children.     

Parental responsibilities: Reformulating the paradigm for parent–child relationships Part 1: What is wrong with the ways in which we deal with the children of separated parents and how to put them right

This is the first part of a two-part article, which calls for the removal of terms such as rights and custody, including joint and shared custody, and visitation from the legal discourse in relation to children and their parents. This part demonstrates how the current discourse, based on the competing rights of the parents, leads inevitably to competitiveness and litigation, which are highly damaging to the child. The proposed paradigm of parental responsibilities requires establishing the needs of the specific child when there are parental disharmony and separation, while emphasizing the joint responsibilities of both parents to ensure that those needs are adequately met. This part also addresses the question: who has parental responsibilities, when a child is born as a result of Assisted Reproductive Technology, and also the quasi-parental role of the court.
