The Role of Physical Function in the Association between Physical Activity and Gait Speed in Older Adults: A Mediation Analysis

Adequate levels of physical function (PF) are essential for vulnerable older adults to perform their daily tasks safely and remain autonomous. Our objective was to explore the mediating role of PF in the relationship between physical activity (PA) and gait speed (GS) in a large sample of older adults from the north of Brazil. This is a cross-sectional study that analyzed 697 older adults (mean age 70.35 ± 6.86 years) who participated in the project "Health, Lifestyle, and Physical Fitness in Older Adults in Amazonas" (SEVAAI). PA was assessed using the Baecke Questionnaire, PF using the Senior Fitness Test, and GS using the 50-foot Walk Test. Mediation pathways were analyzed to test the possible mediating role of PF between specific PA domains (PA-total score, PA-housework, PA-sport, PA-leisure) and GS. Regarding PA-total, the analysis showed that high-performance GS was partially mediated in approximately 19% by better PF performance. Moreover, the PF could partially mediate the association between PA-sport and PA-leisure with GS, at levels of approximately 9% and 46%, respectively. An inverse relationship was observed between PA-housework (sedentary lifestyle) and GS. This association was partially mediated to an extent of approximately 9% by better PF performance. We conclude that PF plays a crucial role in mediating the association between PA and GS among vulnerable older adults.

A First Record of Organochlorine Pesticides in Barn Owls (Tyto alba) from Portugal: Assessing Trends from Variation in Feather and Liver Concentrations

We evaluated feathers as a non-destructive biomonitoring tool documenting organochlorine pesticides (OCP) in liver and checked possible trends in pesticide use in two areas based on OCP concentrations in barn owls (Tyto alba). We measured the concentrations of 16 OCP in 15 primary feathers and 15 livers from barn owl carcasses collected on roadsides in Tagus Valley and Évora regions, south Portugal. Total OCP mean concentration was 8 120 ng g^-1 in feathers and 178 ng g^-1 in livers. All compounds were detected in feathers while in livers δ-HCH, endosulfan sulphate, p,p'-DDT and p,p'-DDD were not detected. The high β-HCH and heptachlor concentrations in feathers most likely derived from external endogenous contamination. P,p'-DDE was the OCP with the highest hepatic concentration. Both matrices indicated an exposure to recently released heptachlor. The differing OCP concentrations between Tagus Valley and Évora seem to reflect differences in land-use and pesticide use histories of the two locations, and/or faster degradation of OCP in the Tagus area.

Walking and cycling, as active transportation, and obesity factors in adolescents from eight countries

BACKGROUND

Evidence has shown that active transportation decreases obesity rates, but considering walking or cycling as separate modes could provide additional information on the health benefits in adolescents. This study aimed to examine the associations between walking and cycling as form active transportation and obesity indicators in Latin American adolescents.

METHODS

Population-based study with 671 adolescents (mean age: 15.9 [standard deviation: 0.8] years) from eight countries participating in the Latin American Study of Nutrition and Health/Estudio Latino Americano Nutrition y Salud (ELANS). Walking and cycling for active transportation were measured using the International Physical Activity Questionnaire long version. Body mass index, waist circumference, neck circumference, and relative fat mass were used as obesity indicators. Associations were estimated using logistic regression models for the pooled data adjusted for country, sex, age, socio-economic levels, race/ethnicity, leisure-time physical activity and energy intake.

RESULTS

Mean time spent walking and cycling was 22.6 (SD: 33.1) and 5.1 (SD: 24.1) min/day, respectively. The median values were 12.8 (IQR: 4.2; 25.7) and 0 (IQR: 0; 6.2) for walking and cycling. Participants reporting ≥ 10 min/week of walking or cycling for active transportation were 84.2% and 15.5%, respectively. Costa Rica (94.3% and 28.6%) showed the highest prevalence for walking and cycling, respectively, while Venezuela (68.3% and 2.4%) showed the lowest prevalence. There was no significant association between walking for active transportation and any obesity indicator. In the overall sample, cycling for ≥ 10 min/week was significantly associated with a lower likelihood of overweight/obesity based on BMI (OR: 0.86; 95%CI: 0.88; 0.94) and waist circumference (OR: 0.90; 95%CI: 0.83; 0.97) adjusted for country, sex, age, socio-economic level, race/ethnicity, leisure-time physical activity and energy intake compared to cycling for < 10 min/week. There were no significant associations between cycling for active transportation and neck circumference as well as relative fat mass.

CONCLUSIONS

Cycling for active transportation was negatively associated with obesity indicators, especially body mass index and waist circumference. Programs for promoting cycling for active transportation could be a feasible strategy to tackle the high obesity rates in adolescents in Latin America.

Predictive Modeling of Injury Risk Based on Body Composition and Selected Physical Fitness Tests for Elite Football Players

Injuries are one of the most significant issues for elite football players. Consequently, elite football clubs have been consistently interested in having practical, interpretable, and usable models as decision-making support for technical staff. This study aimed to analyze predictive modeling of injury risk based on body composition variables and selected physical fitness tests for elite football players through a sports season. The sample comprised 36 male elite football players who competed in the First Portuguese Soccer League in the 2020/2021 season. The models were calculated based on 22 independent variables that included players' information, body composition, physical fitness, and one dependent variable, the number of injuries per season. In the net elastic analysis, the variables that best predicted injury risk were sectorial positions (defensive and forward), body height, sit-and-reach performance, 1 min number of push-ups, handgrip strength, and 35 m linear speed. This study considered multiple-input single-output regression-type models. The analysis showed that the most accurate model presented in this work generates an error of RMSE = 0.591. Our approach opens a novel perspective for injury prevention and training monitorization. Nevertheless, more studies are needed to identify risk factors associated with injury prediction in elite soccer players, as this is a rising topic that requires several analyses performed in different contexts.

The Role of Cognitive Performance and Physical Functions in the Association between Age and Gait Speed: A Mediation Study

Simple Summary

Age and mobility are interrelated. In this context, cognitive performance (CP) and physical functions (PF) play a mediating role. However, these concepts are multifaceted, and their interrelationships need further investigations. Thus, our study aims (1) to investigate the association between CP and PF with GS and (2) to examine whether CP and PF mediate the association between age and GS in a large sample of older Brazilian adults. The findings show that low levels of CP and PF were associated with a greater chance of the older individual presenting a slow GS. Moreover, the mediation model indicated that CP and PF mediated, by approximately 12% and 98%, respectively, the association between age and GS.

Abstract

Introduction: With vulnerable aging, gait speed (GS) undergoes progressive changes, becoming slower. In this process, cognitive performance (CP) and physical function (PF) both play an important role. This study aims (1) to investigate the association between CP and PF with GS and (2) to examine whether CP and PF mediate the association between age and GS in a large sample of Brazilian older adults. Methods: A cross-sectional study analyzed 697 individuals (mean age 70.35 ± 6.86 years) from the state of Amazonas. The CP was evaluated by the COGTEL test battery, PF by the Senior Fitness Test battery, and GS with the 50-foot Walk Test. Results: Older adults with a lower CP and PF had a 70% and 86% chance of slow GS, respectively. When CP and PF were placed simultaneously as mediators, the direct effect estimated by the model revealed a non-significant relationship between age and GS. Specifically, CP and PF mediated the association between age and GS, at approximately 12% and 98%, respectively. Conclusions: CP and PF show the potential to estimate GS performance among older adults. Moreover, CP and PF indicated a negative and direct association between age and slow GS, especially PF.

The Attitude of Portuguese Physical Education Teachers toward Physical Fitness

In this study, we aimed to examine how Portuguese physical education teachers perceive the development of physical fitness through fitness tests in schools. The participants were 764 Portuguese teachers teaching at middle-school and high-school levels. The Physical Education Teacher Attitudes Toward Fitness Tests Scale (PETAFTS) was used to collect the data. The means and confidence intervals for each attitude subdomain and the overall attitude were computed. A one-way ANOVA was used to examine the group differences in three subdomains of the attitudes of teachers by different variables. The overall attitude of teachers toward fitness tests was slightly positive according to a 7-point Likert scale (5.52, 95% CI: 5.47, 5.58). The results suggested that female teachers found fitness tests more useful, but male teachers significantly enjoyed implementing them. The data collected also showed that younger teachers found the implementation of fitness tests significantly more enjoyable than older teachers. In conclusion, future research should prioritise specific intervention content considering gender and the age of teachers to reinforce the development of physical fitness through fitness tests in schools.

Exploring the Role of Physical Activity in Mediating the Association between Educational Level and Health-Related Quality of Life in an Adult Lifespan Sample from Madeira Island

Background: People more socioeconomically vulnerable tend to have a poorer health-related quality of life (HRQoL). Studies are trying to analyse the factors that may condition this relationship, including physical activity (PA), which may influence the relationship between socioeconomic status (SES) and HRQoL. This study aimed to analyse the relationship between SES and HRQoL through specific domains of PA. Methods: A total of 381 adults (≥18 years) from the Autonomous Region of Madeira completed the measurements. Mediation analyses using bootstrapping methods adjusted for confounding variables were performed to relate SES and HRQoL; the latter was evaluated using the physical component score (PCS) of the SF-12, the mental component score (MCS) of the SF-12, and the total score in the SF-12 questionnaire (SF-12 score), through physical activity. Results: Educational level was positively related to PCS and SF-12 score. Leisure-time PA (not including sports PA) and PA at work, as single mediating variables, did not mediate the relationship between SES and HRQoL. The total PA suppressed the socioeconomic gradient of HRQoL by 8–10%, 39–46%, and 15–16%, respectively, for the PCS, MCS, and the SF-12 score; sports PA mediated the relationship by 13–16%, 50%, and 15–21%, respectively. Conclusions: The results suggest that sports PA contributes to reducing the socioeconomic gradient of HRQoL.

Influence of Tactical and Situational Variables on Offensive Sequences During Elite European Handball Matches

The main objective of this study was to analyze the influence of tactical and situational variables on offensive sequences during elite European handball matches. A sample of 55 games and 5.857 offensive sequences from the European Handball Federation Champions League, the selected teams were classified as the top eight teams in the league, were analyzed using X 2 and logistic regression analyses. Results indicated that positional attacks [odds ratio (OR) = 0.34; 95% CI: 0.28-0.42; p < 0.001] and fast attacks (OR = 0.46; 95% CI: 0.36-0.57; p < 0.001) decreased the probability of success for an offensive sequence by 66% and 54% when compared with counterattacks. Offensive sequences that start in the attacking zone seem to be less effective (~78%) than those that start from a situation of "ball in center." Additionally, offensive sequences that finished in the defensive zone of the observed team were 3.19 times more effective than those that ended before the 9 m zone. We concluded that compared with offensive sequences where the shot is performed from the 9 m zone, the chances of an offensive sequence ending successfully are 3.65, 3.60, and 2.21 times higher, for offensive sequences where the shot is performed from 9 m, 6 m, and the defensive zone, respectively. On the other hand, many variables seem to impact the performance of handball teams. Nevertheless, a significant challenge remains, and more research needs to be conducted to analyze the obstacles that teams need to overcome while attacking in the most effective way possible.

Catatonia and dementia: a case report

Introduction

Catatonia is a neuropsychiatric disorder characterized by motor, behavioral and autonomic changes. It is associated with several psychiatric disorders, including dementia. Catatonia is an underdiagnosed syndrome, so it is important to draw attention to it. Here, we review a case of a patient admitted to our psychiatric department with a clinical presentation compatible with catatonia. After proper treatment, further assessment revealed dementia.

Objectives

This work aims to describe a case of catatonia in a patient with dementia.

Methods

Bibliographic research using Pubmed®. Clinical file consultation and patient interviews.

Results

Catatonia is a disorder that was already been described as part of several types of dementia. We present a 69-year-old female patient, admitted to our psychiatric department with clinical presentation compatible with catatonia. To admission, she presented some typical complications resulting from long immobility such as pressure ulcers and nutritional deficiencies. During the hospitalization, she developed a urinary infection and there was the need to tube feeding. She was treated with benzodiazepines and improved. Further assessment revealed dementia.

Conclusions

Catatonia in dementia is not uncommon, although it is an underdiagnosed syndrome, and when treated early and properly it has a good prognosis.

Role of migration in the development of a first episode of psychosis

Introduction

Currently, there is scientific evidence supporting the relationship between socio-environmental factors and the onset of a first episode of psychosis (FEP). In this context, the phenomenon of migration, seen as a negative life experience, may become an important risk factor in developing a psychotic disorder (PD). In Europe, the impact of this phenomenon is growing and, therefore, it’s necessary to provide a proper answer to these individual’s mental health problems.

Objectives

Identify which phases of this migration process are most important in the development of a FEP and what are the more significant socio-environmental factors in each phase.

Methods

Bibliographic research in Pubmed database using the terms “Migration” and “First Episode Psychosis”.

Results

Research confirms that migrants have a 2 to 3-fold increased risk of developing a PD. This risk will be even higher in the refugee population. Pre- and post-migration factors demonstrated to be more important than factors related with the migration process itself. In the pre-migration phase highlight factors like the lower parental social class and a previous trauma. In the post-migration phase highlight factors like discrimination, social disadvantage and a mismatch between expectations and reality.

Conclusions

Literature is unanimous in considering migrant status as an independent risk factor for the development of FEP, possibly due to the outsider’s role in society. Thus, despite the growing interest in Biological Psychiatry, this work demonstrates that socio-environmental factors are very preponderant in the development of these disorders and because of that further investigation is still necessary.

“Walking with myself by my side” - non-medical use of Ketamine

Introduction

Ketamine, synthesized in 1962 as phencyclidine derivate, is denominated a “dissociative anesthetic” because of its side-effects, such as dissociative episodes and psychotic-like symptoms, which have limited its applicability on clinical practice. Otherwise, in the last decades the non-medical use of ketamine has been growing and today is one of the most popular illicit substances consumed between adolescents and young adults.

Objectives

Increasing the knowledge and understanding of the factors related to crescent use of ketamine and the experiences and consequences associated to its consumption.

Methods

Clinical interview with patients diagnosed with ketamine use disorder and bibliographic research in Pubmed database using the terms “Ketamine use” and “Ketamine addiction”.

Results

Pat et al. (2002) describes a clinical case of a young male, diagnosed with substance use disorders, specifically alcohol and cocaine use disorders, that started a treatment with ketamine. After the treatment, pleasant depersonalization experiences contributed to the development of patient’s ketamine dependence. Other patient’s reports confirm the association of ketamine use with psychedelic effects and dissociative episodes and pointed these effects as main reason for its consumption.

Conclusions

The adverse effects that limited the medical use of ketamine are the same that promote its utilization with recreational purposes by adolescents and young adults in parties and nightclubs. About the ketamine dependence, the literature is scarce and doesn´t clearly identify a physical withdrawal syndrome, pointing only to a serious psychological dependence. Thus, with the crescent non-medical use of ketamine, it’s urgent to develop an intervention plan directed to this problem.

AB1565-HPR REHABILITATION NURSES KNOWLEDGE ABOUT OSTEOPOROSIS AND FRAGILITY FRACTURES IN PORTUGAL

Background

Scientific evidence reveals gaps in health professionals’ knowledge about osteoporosis and fragility fractures, which impairs and influences the quality of care, namely in preventive actions.

Objectives

To analyse knowledge of Rehabilitation Nurses about osteoporosis and fragility fractures to identify training needs of Rehabilitation Nurses.

Methods

A cross-sectional study, integrated in a larger project, using an adapted questionnaire, made available online and disseminated by mailing list of “Ordem dos Enfermeiros” (Royal Colleague of Nursings) to all Portuguese Rehabilitation Nurses.

Results

There were include 452 participants(10.3% of the 4 397 Rehabilitation Nurses), 17% perform functions in orthopaedics and traumatology service, 4.5% physical medicine and rehabilitation and 78.6% in other services, majority, 74.6% women. On average, 69.6% correct answers were identified regarding osteoporosis and fragility fractures. Results reveal that the main areas of knowledge deficit, in this study, are related to the concept and epidemiology of osteoporosis and fragility fractures and about the most appropriate diet. Nurses with higher academic degree (master’s degree) revealed more knowledge (p=0.01).

Conclusion

This study reveals that the knowledge about osteoporosis and fragility fractures is low (<70% correct answers), thus there is an opportunity to improve the knowledge related to osteoporosis and fragility fractures among Specialist Nurses in Rehabilitation Nursing.

Dissociation and emotional dysregulation in pathological personalities related to the fear of SARS-COV-2: a case report

Introduction

The COVID-19 pandemic represented a serious strain on the mental health resilience worldwide. Implementation of restrictive rules implied the disruption of social networks, eliciting emotional exhaustion and intense response to fear. This was amplified by media spread of panic and fake news, representing risk factors for post traumatic stress disorder (PTSD). Fear can be dangerous, especially accounting premorbid psychopathological vulnerability, such as pathological personality traits. Emotional dysregulation increases fear levels, mediated by the relationship between emotional dysregulation and lack of tolerance.

Objectives

Clinical case presentation of patient who developed dissociative and behavioral symptoms following COVID-19 infection. Bibliographic research.

Methods

Bibliographic research using Pubmed®. Clinical file consultation and patient interviews.

Results

Heightened psychophysiological reactivity can result from the persistent fear experienced during a traumatic event and repeated memories related to it, leading to a sensitization of the response to fear. We present 57 year-old female patient, admitted to the COVID ward after trying to escape from home isolation due to positivity to COVID-19. In the hospital setting she developed dissociative symptoms, trying to escape from the ward and infect other people.

Conclusions

Intense fear responses to COVID-19 are likely explained by poor emotion regulation capacities as well as dissociative mechanisms. Studies have shown that this pandemic was experienced as a real traumatic event and some studies have found that it may lead to the development of PTSD. Pathological personality is positively related to PTSD symptoms, attributable to higher levels of mood instability, cognitive/perceptual disorders, interpersonal dysfunctions and negative affection.

POS0380 EFFECTIVENESS OF REMOTE CARE INTERVENTIONS: A SYSTEMATIC REVIEW INFORMING THE 2022 EULAR POINTS TO CONSIDER FOR REMOTE CARE IN RHEUMATIC AND MUSCULOSKELETAL DISEASES

Background

While the number of patients with rheumatic musculoskeletal diseases (RMDs) is increasing worldwide, there is no adequate increment in the number of health care professionals, leading to the urgent need for new forms of care to take pressure from health care systems.1 2 Telehealth comprises a number of different types of interventions with the scope of performing certain steps of care, ranging from diagnostics to follow-up visits, in a remote manner. The use of remote care is heterogenous and guidance is needed to optimize the combination with conventional face-to-face (F2F) visits.

Objectives

To perform a systematic literature review (SLR) on different outcomes of remote care compared to F2F care, its implementation into clinical practice and to identify drivers and barriers in order to inform a task force formulating the European Alliance of Associations for Rheumatology (EULAR) Points to Consider for remote care in RMDs.

Methods

Prospective, retrospective, and qualitative studies testing different types of remote care in patients with RMDs were included. Medline, Embase and the Cochrane Library were searched through February 28th, 2021. Two reviewers independently performed standardized data extraction, synthesis, and risk of bias assessment.

Results

A total of 2,240 references were identified. Forty-seven studies, consisting of 26 randomized controlled trials, 8 prospective cohort studies, 8 cross sectional studies, and 5 qualitative studies were included.

Fifty-one percent of the studies involved patients with inflammatory RMDs, including rheumatoid arthritis, and spondyloarthritis, while 49% were on patients with non-inflammatory conditions, such as osteoarthritis and fibromyalgia. Remote monitoring (n=35) was most frequently studied, with telephone/video calls being the most common mode of delivery (n=30). Thirty-four studies investigated outcomes of remote care in comparison to F2F care. The most frequently assessed outcomes concerned efficacy and user perception of remote care, with 34% and 21% of studies, respectively, reporting superior results for the remote care intervention.

Time savings and flexibility were reported as major drivers, while inadequate technical knowledge and concerns in data security were the main barriers to implementing remote care. Implementation of remote care methods into clinical practice was not reported by the included studies. The main limitations were the heterogeneity of outcomes and interventions, and the substantial risk of bias (50% of studies with high risk of bias).

Conclusion

Studies on remote care reported similar to partially better results compared to F2F care concerning efficacy, and user perception outcomes, with the limitation of heterogeneity and considerable risk of bias.

OP0001 “I WILL NEVER FORGET THE SHAME I FELT”: A SURVEY TO PEOPLE WITH A RHEUMATIC DISEASE ABOUT INVALIDATION FROM HEALTH PROFESSIONALS AND OTHER PEOPLE

Background

The term invalidation refers to the patients’ perception that their medical condition is not recognised, either in denying, lecturing, not supporting or not acknowledging the condition. This may be the felt from health professionals themselves but also from family, friends, at work and in other social areas, imposing great suffering.[1] The European Alliance of Associations for Rheumatology (EULAR) has made efforts to raise awareness for the burden imposed by rheumatic and musculoskeletal conditions (RMDs) and promote the best quality of care, including recognition and psychosocial support. However, it is unclear how frequent and severe the problem remains nowadays.

Objectives

The aims of this national survey were: (i) to identify the levels of invalidation and lack of understanding felt by adults with RMDs from health professionals and other people, (ii) to investigate the relationship between invalidation, sociodemographic characteristics and disease; and (iii) to understand its impact on people’s life and health outcomes.

Methods

An online survey was developed by the national health professionals in rheumatology and patients’ organisations and opened between May and December of 2021. The questionnaire included demographic and disease information, the Illness Invalidation Inventory (3*I),[1] with additional questions in a Likert format and open questions for a detailed understanding of the phenomenon. The 3*I is composed of 8 items, measured from 1 (=never) to 5 (=very often), forming two factors: Discounting (mean of 5 items; lower scores indicating more discounting) and Lack of understanding (mean of 3 items; Higher scores representing higher lack of understanding).

Quantitative data were analysed using descriptive statistics. Associations were tested with a t-student and ANOVA one-way test (Bonferroni correction). Open responses were categorised using the content analysis technique, and themes were defined a posteriori.

Results

From the > 1500 responses obtained, 1410 responses were filled out completely (mean age of 46 years [SD=11], 95% females, 60% with FM, among which 59% were diagnosed in the last 5 years).

Invalidation was reported by 86% of the participants and 70% rated ≤5 on a scale from 0 (nothing) to 10 (totally) on feeling understood by other people. Invalidation was mostly felt from family (56%), health professionals (48%), friends (39%) and social environment (38%). The impact of this invalidation is mainly on the psychological well-being (58%), also reducing seeking health care (41%) and therapeutic adherence (17%), affecting work (41%), and to a less extent, (family) relations (31%).

Figure 1 shows the frequency of responses and means scores on the 3*I items and factors for participants with and without FM. The burden is greater for people with FM, which was statistically significant. People with higher education felt more discounting and more lack of understanding. No differences (p>0.05) were observed for gender or civil status.

Figure 1.

Percentages of responses per type of disease for the eight items of the Illness Invalidation Inventory.

Elucidative expressions of invalidation were shared, mostly by people with FM, encompassing their ability to work and need for social support, faking pain and treatment efficacy, and even intimacy aspects. These emotionally uncomfortable situations can be linked to lesser engagement with healthcare and disease management, and therefore, with worse health outcomes.

Conclusion

Invalidation remains a source of suffering, affecting well-being and health outcomes. Specific awareness and educational campaigns are needed to target this problem on different play-actors.

Cognitive Reserve Mediates the Relation between Neighborhood Socio-Economic Position and Cognitive Decline

<b><i>Introduction:</i></b> We investigated the mediating role of leisure activity engagement as marker of cognitive reserve in the relation between neighborhood socio-economic position (SEP) and cognitive decline over 6 years. <b><i>Methods:</i></b> The study analyzed longitudinal data from 897 older adults who participated in the two waves (2011 and 2017) of the Vivre-Leben-Vivere (VLV) survey in Switzerland (<i>M</i> = 74.33 years in the first wave). Trail Making Test parts A and B were administered in both waves. Leisure activity engagement was assessed during interviews. Neighborhood SEP was derived from the Swiss Neighborhood Index of Socio-Economic Position (Swiss-SEP), provided by the Swiss National Cohort (SNC). <b><i>Results:</i></b> Latent change score modeling revealed that 42.5% of the relationship between higher neighborhood SEP and smaller cognitive decline was mediated via a higher frequency of leisure activities in the first wave. <b><i>Conclusion:</i></b> Neighborhood SEP constitutes an important contextual factor potentially influencing the pathways of cognitive reserve accumulation and, therefore, should be taken into account to better understand their effects on cognitive decline in old age.
