Background and objectivesThe ageing population and the increasing dependency associated with it, makes the caregiver a highly relevant figure nowadays. The present study analyzes the socio-demographic differences between family and professional caregivers and their satisfaction and implication in a training program for caregivers.MethodsThe sample consisted of 59 caregivers of older people (37 were family caregivers and 22 professional caregivers) which received and implemented a caregivers training program in their daily care functions. These caregivers were trained in communication skills and cognitive stimulation strategies so they could use them in their daily care activities with the older adults under their care during a period of 3 months. All the participants were assessed with a socio-demographic questionnaire, 2 questionnaires to analyze their satisfaction with their work and the training received and one questionnaire to analyze their ability to detect and react to memory and behavior problems in the older adults they attended.ResultsThe results showed socio-demographic differences, improvements in satisfaction in family caregivers and a greater commitment in their daily work after the treatment in both groups although these effects could be due to different reasons.ConclusionsThe research shows the benefits of carrying out training programs for caregivers as they significantly increase the quality and satisfaction with caregiving. The study also displays the need to adjust such programs taking into account that the socio-demographic characteristics and training needs are different depending on whether de caregiver is a family member or a professional. 相似文献

Objective
To determine the frequency of successful aging (SA) and its relationship with frailty in an elderly population.Material and methods
An analytical cross-sectional study of subjects ≥60 years of age seen as outpatients in a general hospital. Successful aging was defined as scores of ≥ 90 in the Barthel index and ≤ 2 in the Pfeiffer test. Frailty was determined using the Fried criteria.Results
The study included 400 subjects (272 women and 128 men), with a mean age of 71.6 ± 8.2 years. The SA frequency was 40.4%. frail status was statistically higher in non-successful aging subjects than in SA subjects (161.7 versus 7.9%; P<.001). Women were more frequently frail, while being a pensioner/retired and married were associated less frequently with frailty.Conclusions
Successful aging is associated with a lower level of frailty. 相似文献35.

Medical students are at higher risk for depression, affecting not only their lives but also patient care. This article studied a population of medical students engaged in lecture‐based learning regarding the presence of depressive symptoms and its relation to morningness‐eveningness. Depressive symptoms were assessed by the Beck Depressive Inventory scale (BDI>10), and diurnal preference was assessed by the Horne & Östberg Morningness/Eveningness Questionnaire (MEQ). Family history of depression and involvement in regular physical activity were also investigated. A total of 161 students, 77 (47.8%) males, aged 19 to 30 yrs (22.1±2.1) living in a city close to the equator were evaluated. Fifty‐three individuals (32.9%) had depressive symptoms. Depressive individuals showed a trend to be female (p=0.07). Also, female gender showed a non‐significant shift toward morningness. Fifty‐eight (36.0%) subjects participated in regular physical activity. In 57 cases (35.4%), there was a history of depression in the family. Fifteen individuals (9.3%) were definitely evening type, 42 (26.1%) were moderately evening type, 44 (27.3%) were indifferent, 42 (26.1%) were moderately morning type, and 18 (11.2%) were definitely morning type. Family history of depression (OR=0.29, 95% CI=1.37–6.12) and sedentary life (OR=0.28, 95% CI=0.12–0.65) were associated with depressive symptoms. Eveningness was associated with depressive symptoms (OR=0.66, 95% CI=0.50–0.88), and this association remained significant after adjusting for the presence of familial depression and physical activity (OR=0.71, 95% CI=0.52–0.95). In conclusion, depressive symptoms are independently associated with “eveningness” in medical students. These results should be confirmed by future studies involving a larger number of subjects. 相似文献

Background The aim of the present study was to evaluate the knowledge and perception of depression among students of University Sains Malaysia (USM), in Penang, Peninsular Malaysia.Method Face-to-face interviews were conducted using a pre-validated 21-item questionnaire among students at USM.Results A total of 500 respondents participated in the survey comprising 24.6% (n=123) males and 75.4% (n=377) females. Half (50.0%, n=250) were Malays, followed by Chinese (44.0%, n=220) and Indians (6.0%, n=30). Whilst exploring the respondents' knowledge of the symptoms of depression, it was found that Chinese females had a comparatively better knowledge (P=0.058) of the symptoms of depression in comparison with Malays and Indians. Overall, social issues were attributed as the possible cause of depression. A cursory knowledge level was observed regarding medication for depression. Female students were more inclined towards the use of alternative and traditional medicines. However, with regard to seeking professional help, consultation with a psychiatrist was preferred by the majority.Conclusion Overall, a moderate level of knowledge about the symptoms of depression and a cursory knowledge of its therapy were observed. Those with personal experience of depression had better knowledge of the symptoms and therapy. Alternative treatments and traditional medicines were also favoured. There is a risk that this may affect the ability of Malaysian youths to seek evidence-based mental health care. 相似文献

Background: Vaccination is an important preventative measure against the coronavirus disease 19 (COVID-19) pandemic. To implement vaccination and immunization programs effectively, it is essential to investigate public attitudes toward COVID-19 vaccines. This study examined the attitudes of Chinese college students toward COVID-19 vaccines and their associated factors. Methods: A cross-sectional study was conducted in college students nationwide from December 27, 2020 to January 18, 2021. Attitudes toward COVID-19 vaccines and acceptance of future vaccination programs were assessed. Results: Totally, 2,881 college students participated in this survey; of them, 76.3% (95% CI: 74.8% - 77.9%) were willing to accept a COVID-19 vaccine in the future. Multiple logistic analysis revealed that students living in urban (OR=1.409, 95% CI: 1.152 - 1.724, p=0.001) and those studying health-related courses (OR=1.581, 95% CI: 1.291 - 1.935, p<0.001) were more likely to have a positive attitude toward COVID-19 vaccines. In addition, those who were worried about being infected with COVID-19 (very much vs no, OR=1.690, 95% CI: 1.212-2.356, p=0.002), heard previously about COVID-19 vaccines (OR=1.659, 95% CI: 1.268-2.170, p<0.001), believed that vaccines are safe (Yes vs No, OR=3.570, 95% CI: 1.825-6.980), thought that vaccines can protect people from being infected with COVID-19 (Yes vs No, OR=1.957, 95% CI: 1.286-2.979, p=0.002), and had encouraged their family and friends to have a vaccine (Yes vs No, OR=17.745, 95% CI: 12.271-25.660, p<0.001) had higher acceptance of COVID-19 vaccination. Conclusions: A high rate of acceptance of COVID-19 vaccines was found among Chinese college students. However, vaccine uptake may be reduced by concerns about vaccine safety and efficacy. Alleviating these concerns and enhancing public confidence in vaccines are crucial for future immunization programs against the COVID-19 pandemic. 相似文献

BackgroundElevated manganese (Mn) exposure impairs cognition in adults and children, but the association between Mn and cognitive function in elderly people is unclear. Previous studies have linked Mn neurotoxicity in AD to Aβ-dependent mechanisms. However, the association between Mn and plasma APP and Aβ in the general elderly population remains unknown. This study aimed to investigate the association between Mn exposure and cognitive function, plasma APP and plasma Aβ in older adults.MethodsCognitive abilities in 375 men aged 60 and older in Guangxi, China were assessed using the Mini-Mental State Examination (MMSE) and cognitive impairment were identified using education-stratified cut-off points of MMSE scores. Urinary Mn levels and plasma APP, and Aβ levels were measured using ICP-MS and ELISA, respectively.ResultsA total of 109 (29.07 %) older men were identified as having cognitive impairment. The median urinary Mn level was 0.22 μg/g creatinine. Urinary Mn levels were negatively correlated with MMSE scores (β = −1.35, 95 % CI: −2.65 to −0.06; p = 0.041). In addition, higher concentrations of urinary manganese were associated with a greater risk of cognitive impairment (OR = 2.03, 95 % CI: 1.14–3.59; comparing the highest and lowest manganese; p = 0.025). Moreover, plasma APP levels were inversely associated with urinary Mn levels (r = −0.123, p = 0.020), and positively associated with MMSE scores (r = 0.158, p = 0.002). Surprisingly, no correlations were observed between plasma Aβ42, Aβ40, Aβ40/Aβ42, or Aβ42/Aβ40 and urinary Mn levels and MMSE scores.ConclusionThese results suggested that Mn exposure is negatively associated with older men’s cognition and plasma APP levels, but not plasma Aβ levels. 相似文献

In this article, we describe an 8- to 10-day inquiry safari designed for middle/high school students to investigate hominid
evolution using replica skulls of extant and extinct vertebrates. Students begin the unit using their own skulls and proceed
to use the replica skulls of extant vertebrates to construct an understanding of how skulls can be used to interpret and infer
diets, dentition, dental formulae, bipedal or quadrupedal locomotion, and the social structure of animals. They are then able
to use this knowledge to construct similar inferences for extinct fossil hominids. Using radiometric dating data, the students
develop possible phylogenetic pathways for hominid evolution. The lessons promote the use of inquiry skills including journaling,
observing, drawing, puzzle-making, using taxonomic keys, and investigating into deep geological time. 相似文献
