Productivity among older adults manifests in engagement in paid work, voluntary work, giving support to others, home maintenance and housekeeping. This paper reports an investigation into the extent to which levels of participation in the different productive activity types in The Netherlands are associated with age, gender and the settings in which older people live. The regional and urban–rural dimensions of variation are examined. The data were derived from the European Study of Adult Well-Being survey (ESAW). The results show that the oldest women tended to restrict their productivity to the private domain of housekeeping, while the oldest men were more often productive in the community, and that regional variations were stronger for women than for men. Traditional gender roles particularly affected the way in which older women living in a peripheral region participated in productive activities. In contrast, the urban–rural dimension was more important for men than for women, partly because a group of older men in the cities were not involved in paid work. Overall, strong gender influences on the variations in productive engagement were found. Processes of age-related contraction and convergence in patterns of participation in productive activities were imputed from the cross-sectional data. A full understanding of the ageing and cohort effects underlying the reported patterns would require much more detailed information on the spatial and temporal dimensions of older people's activity patterns.

AbstractHabitual loading patterns of domesticated animals may differ due to human influence from their wild counterparts. In the early stages of human-reindeer interaction, cargo and draft use was likely important, as well as corralling tame reindeer. This may result to changes in loading as increased (working) or decreased (captive) loading, as well as foraging patterns (digging for lichen from under the snow versus fed working and/or captive reindeer). Our aim is to study whether differences in activity modify variation in bone cross-sectional properties and external dimensions. Our material consists of donated skeletons of modern reindeer: 20 working reindeer (19 racing and one draft), 24 zoo reindeer, and sample of 78 free-ranging/wild reindeer as a reference group. We used general linear modelling to first establish the total variation in cross-sectional properties among wild and free-ranging reindeer, and then to infer how differences in loading modify observed variation among zoo and working reindeer. According to our results, direction of greater bone quantity as well as external dimensions in of radioulna of female reindeer differs from female reference group, likely relating to foraging behavior. External dimensions of humerus differ in working and zoo male reindeer compared to male reference group. Increased robusticity of long bones, especially of tibia among working male reindeer, may indicate increased loading, and increased cortical area of long bones may indicate sedentary lifestyle among female reindeer. The results of this study can be used to understand early stages of reindeer domestication by observing reindeer activity patterns from archaeological material.

Pathological changes in the prostate gland occur commonly with advancing age including inflammation, atrophy, hyperplasia and carcinoma and a change in volume is also evident. Estimation of volume of prostate may be useful in a variety of clinical settings. A cross-sectional descriptive study was designed to see the changes in volume of the prostate with advancing age and done in the Department of Anatomy, Dhaka Medical College, Dhaka from August 2006 to June 2007. The study was performed on 70 post-mortem human prostates collected from the unclaimed dead bodies that were under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into three age groups; group A (10-20 years), group B (21-40 years) and group C (41-70 years). Volume of the sample was measured by using the ellipsoid formula. The mean ± SD volume of prostate was 7.68 ± 3.64 cm3 in group A, 10.61 ± 3.99 cm3 in group B and 15.40 ± 6.31 cm3 in group C. Mean difference in volume between group A and group C, group B and group C were statistically significant (p<0.001). Statistically significant positive correlation was found between age and volume of prostate (r = + 0.579, p < 0.001). Key Words: Prostate; volume; Bangladeshi. DOI: 10.3329/imcj.v4i2.6501Ibrahim Med.

Physically Active

Background: No specific physical activity guidelines are available for women in multiple pregnancy. Aim of the study was to assess the knowledge and experience of women regarding physical activity during their latest twin pregnancy. Methods: A cross-sectional study including women after a twin delivery was conducted in Poland. A questionnaire was distributed in 2018 via web pages and Facebook groups designed for pregnant women. Results: 652 women filled out the questionnaire completely. Only 25% of women performed any physical exercises during twin gestation. The frequency of preterm delivery was similar in physically active and non-active participants. 35% of the respondents claimed to have gained information on proper activity from obstetricians during antenatal counselling while 11% claimed to be unable to identify the reliable sources of information. 7% of women admitted to feel discriminated by social opinion on exercising during a twin pregnancy. Conclusions: The population of women with a twin gestation is not sufficiently physically active and is often discouraged from performing exercises during gestation. Therefore, it is crucial to inform obstetricians to recommend active lifestyle during a twin gestation and to provide reliable information on physical activity to pregnant women. Further research on this topic is necessary in order for obstetric providers to counsel women on appropriate exercise with a twin pregnancy.

Purpose: This work evaluated the use and type of dietary supplements and home monitoring for nonneovascular age-related macular degeneration (AMD), as well as the prevalence of genetic testing among patients with AMD. Methods: A cross-sectional study was conducted of 129 participants older than 50 years who completed self-administered questionnaires regarding usage and type of dietary supplements and home monitoring, as well as the participants’ use of genetic testing for AMD. Results: Of 91 participants with AMD, 83 (91.2%) took vitamins, including 55 (60.4%) who used an Age-Related Eye Disease Study (AREDS) or AREDS2 formulation. Of 38 without AMD, 31 (81.6%) took vitamins (difference from participants with AMD = 9.6% [95% CI, 0%-23.2%]), including 2 on an AREDS formulation. Among 82 participants with AMD who were AREDS candidates (intermediate or advanced AMD in 1 or both eyes), 51 (62.2%; 95% CI, 51.7%-72.7%) took an AREDS or AREDS2 formulation, and 31 (37.8%) did not (5 were unsure). Additionally, 50 (61.0%; 95% CI, 50.4%-71.6%) AREDS candidates did some type of home monitoring. Only 1 (1.2%; 95% CI, 0%-3.6%) underwent genetic testing for AMD. Among 9 with AMD who were not AREDS candidates, 4 (44.4%) used an AREDS formulation, 4 (44.4%) did not, and 1 (11.1%) was unsure; only 1 (11.1%) of these 9 performed home monitoring. Conclusions: Despite similar results from past surveys and AREDS2 data supporting supplement use in 2013 and home monitoring in 2014, these findings suggest about one-third of AREDS candidates do not do so, providing further support for improving education regarding appropriate supplement and home monitoring usage. Genetic testing for AMD also appears infrequent.

Background:Detection of subclinical enthesitis and synovitis in psoriatic arthritis (PsA) is prevalent and ultrasound (US) examination is informative tool for it diagnosing. Aging positively affects degenerative changes.Objectives:To study relationship between US articular and entheseal findings with age in patients with PsA.Methods:57 patients were enrolled to study with fulfilled PsA criteria (CASPAR, 2009). Data collection: demographical, clinical (current psoriasis, axial involvement, enthesitis, dactylitis), US (synovitis count (by Grey Scale), Power Doppler(PD)+ synovitis), thickening and hypoechogenicity at enthesis, PD+ enthesitis, entheses with structural components); biological (high sensitive C-reactive protein (hsCRP), Erythrocyte Sedimentation Rate (ESR).US examination included 798 joints and 3078 entheses (bilateral shoulders, acromioclavicular joints, elbows, wrists, hips, knees, ankles; entheses at the projection of these joints (total number - 54). US entheseal findings were fixed according to consensus-based US definition and scoring for enthesitis in spondyloarthritis and PsA (OMERACT US)1.Results:In all 57 patients: male - 25 (43.9%), mean age 43.4±10.3(SD) years (y), PsA duration was 7 (3;10) y, Ps duration 10 (8; 22) y; 53 (41.1%) had axial involvement, 42 (73.7%) dactylitis, 8 (14%) clinical enthesitis, and 56 (98.2 %) skin psoriasis, Psoriasis Activity and Severity Index score 6.4 (2;14.4), Disease Activity in PsA score 18.1 (10.2;26.1), hsCRP 10.1(2.4;21.4), ESR 20 (11.3;31.5).Synovitis count increased with age noticeably (r=0.508, p<0.01), and weak correlation of PD+ synovitis (r=0.262, p=0.049) and age was found. The entheseal thickening and hypoechogenicity and structural findings increased with age respectively (r=0.345, p=0.009; r=0.337, p=0.01). There was no correlation between PD+ enthesitis and age. The assosiation between PD+ enthesitis and blood biomarkers of inflammation (hs-CRP (r=0.364, p=0.008); ESR (p=0.358, p=0.008) was found.Conclusion:Our study found significant relationship between age and US synovitis. Association between age and US entheseal involvement was noted. Only PD+ enthesitis was not related with age in comparison with other US entheseal findings. The presence of PD US signal at enthesitis in association with increased inflammatory blood biomarkers can be evaluated as the sign of disease activity regardless of age and not as age-related lesion in PsA patients.References:[1]Balint PV, Terslev L, Aegerter P et al.

Abstract Introduction Periodontitis is a chronic inflammatory disease affecting the periodontium, ultimately leading to looseness and/or loss of teeth. Sarcopenia refers to age-related reduction in muscle mass and strength. Similar to periodontitis, chronic low-grade inflammation is thought to play a key role in its development. In addition, both increase in prevalence with advancing age. Despite known associations with other diseases involving a dysregulated inflammatory response, for example rheumatoid arthritis,, the relationship between periodontitis and sarcopenia, and whether they could be driven by similar processes, remains uncertain. The aim of this study was to explore the association between periodontitis and sarcopenia. Methods Observational study of 2040 adult volunteers [age 67.18 (12.17)] enrolled in the TwinsUK cohort study. Presence of tooth mobility and number of teeth lost were used to assess periodontal health. A binary variable was created to define periodontitis. Measurements of muscle strength, muscle quality/quantity and physical performance were used to assess sarcopenia. A categorical variable was created according to the European Working Group on Sarcopenia in Older People (EWGSOP2) consensus, to define sarcopenia (1: probable; 2: positive; 3: severe). Generalised linear mixed model analysis used on complete cases and age-matched (n = 1,288) samples to ascertain associations between periodontitis and sarcopenia. Results No significant association was found between periodontitis and sarcopenia in both the complete cases analysis and age-matched analysis. Results were consistent when analysis was adjusted for potential confounders including body mass index, frailty index, Mini Mental State Examination smoking, nutritional status and educational level. Conclusions This study found no significant association between periodontitis and sarcopenia in a cohort of 2040 adults. Although both periodontitis and sarcopenia have been linked to a dysregulated immune response and demonstrate an increase in prevalence with increasing age, our work is inconclusive due to the plethora of possible aetiopathogenetic pathways.
