The Impact of Frailty on the Relationship between Life-Space Mobility and Quality of Life in Older Adults during the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic has led to abrupt restrictions of life-space mobility. The impact of shelter-in-place orders on older adults' health and well-being is still unclear. OBJECTIVE: To investigate the relationship between life-space mobility and quality of life (QoL) in older adults with and without frailty during the COVID-19 pandemic. DESIGN: Multicenter prospective cohort study based on structured telephone interviews. SETTING: Four geriatric outpatient clinics in the metropolitan area of Sao Paulo, Brazil. PARTICIPANTS: 557 community-dwelling adults aged 60 years and older. MEASUREMENTS: The Life-Space Assessment was used to measure community mobility before and during the COVID-19 pandemic, and a previously validated decrease of ≥ 5 points defined restricted life-space mobility. Frailty was assessed through the FRAIL (fatigue, resistance, ambulation, illnesses, and loss of weight) scale. The impact of shelter-in-place orders on QoL was evaluated with the question «How is the COVID-19 pandemic affecting your QoL?¼, to which participants could respond «not at all¼, «to some extent¼, or «to a great extent¼. We used ordinal logistic regressions to investigate the relationship between restricted life-space mobility and impact on QoL, adjusting our analyses for demographics, frailty, comorbidities, cognition, functionality, loneliness, depression, and anxiety. We explored whether frailty modified the association between life-space mobility and impact on QoL. RESULTS: Participants were on average 80±8 years old, 65% were women, and 33% were frail. The COVID-19 quarantine led to a restriction of community mobility in 79% of participants and affected the QoL for 77% of participants. We found that restricted life-space mobility was associated with impact on QoL in older adults during the pandemic, although frailty modified the magnitude of the association (P-value for interaction=0.03). Frail participants who experienced restricted life-space mobility had twice the odds of reporting an impact on QoL when compared with non-frail individuals, with respective adjusted odds ratios of 4.20 (95% CI=2.36-7.50) and 2.18 (95% CI=1.33-3.58). CONCLUSION: Older adults experienced substantial decreases in life-space mobility during the COVID-19 pandemic, and this unexpected change impacted their QoL. Providers should be particularly watchful for the consequences of abrupt life-space restrictions on frail individuals.

[Atherosclerotic risk factors in adolescence] / Fatores de risco para doença aterosclerótica na adolescência.

OBJECTIVE: To assess the impact of atherosclerotic risk factors on adolescence. METHODS: Nonsystematic literature review. RESULTS: The progression and severity of atherosclerosis are related to the presence (number), magnitude and duration of some risk factors. CONCLUSIONS: Preventive health measures should be early implemented in order to ensure a healthy childhood and adolescence, and avoid future cardiovascular disease.

Risk factors for atherosclerosis in students of a private university in São Paulo-Brazil.

OBJECTIVE: To characterize the risk profile for atherosclerosis (AS) in adolescents and young adults of a private university in São Paulo. METHODS: Clinical, nutritional, and laboratory parameters were evaluated in 209 students of both genders aged 17 to 25 years. In addition to determination of the lipid profile, the association of its abnormal values with other risk factors for AS was also investigated. RESULTS: Increased levels of total cholesterol, LDL-C and triglycerides (TG) were observed in 9.1%, 7.6% and 16.3% of the students, respectively, and decreased levels of HDL-C in 8.6% of them. Prevalence of the remaining risk factors analyzed was elevated: sedentary life style (78.9%); high intake of total fat (77.5%); high cholesterol intake (35.9%); smoking, hypertension (15.8%) and obesity (7.2%). There was an association between elevated LDL-C and TG levels and sedentary life style and body mass index. CONCLUSION: The high prevalence of risk factors for AS in young individuals draws attention to the need for adopting preventive plans.

[Evaluation of efficacy and safety of etofibrate in primary hyperlipidemia. A multicenter study]. / Avaliação da eficácia e segurança do etofibrato em pacientes dislipidêmicos. Estudo multicêntrico.

PURPOSE: To evaluate the clinical efficacy of etofibrate in primary hyperlipidemia in patients from clinical centers representative of all main Brazilian cities. METHODS: One thousand, nine hundred and fourty three hyperlipidemic patients were submitted to diet and drug treatment with etofibrate (500 mg/day) for eight weeks. The data b WAS analyzed as to changes in the lipoprotein profile, as well as the side effects. RESULTS: There was an important reduction in total cholesterol (19.88%), triglycerides (29.59%), LDL-c (14.89%) and VLDL-c (14.54%) concentration. There was a significant increase in HDL-c (18.14%). Adverse effects were observed in 8.5% of the patients, without major clinical relevance, however, in 1.44% the treatment had to be interrupted. CONCLUSION: Administration of etofibrate promoted positive changes in all parameters of the lipid and lipoprotein profile, thus reducing the risk of atherosclerotic disease, without significant side effects in the great majority of sample studied.

[Lipid changes of fibrinogen and of platelet aggregation induced by etofibrate]. / Modificações lipídicas do fibrinogênio e da agregação plaqutária induzidas pelo etofibrato.

PURPOSE: To evaluate modifications on lipid profile, fibrinogen and platelet aggregation induced by etofibrate. METHODS: Twenty-one adult patients were studied. They all had primary hyperlipidemia and had already been on the AHA step I diet and placebo. Etofibrate (500mg/day) was administered for 60 days in the active phase, when lipid parameters, fibrinogen and platelet aggregation were measured. RESULTS: The % significant reductions were: total cholesterol (-9.50%), LDL-cholesterol (-7.88%), triglycerides (-19.07%), total cholesterol/HDL-cholesterol(-11.90%), LDL-cholesterol/HDL-cholesterol (-10.20%), fibrinogen (-12.79%), platelet aggregation with adrenaline (-24.02%), with ADP 1 mumol (-30.13%), and ADP 3 mumol (-24.51%). CONCLUSION: The beneficial effects of etofibrate were observed not only on the lipid profile but also on the thrombogenic parameters measured by fibrinogen and platelet aggregation.

[Characteristics of the demand for cranial computerized tomography: reasons and costs of the exam]. / Características da demanda por tomografia computadorizada crânio-encefálica. Motivos e custos dos exames.

It was reviewed a series of 2860 cerebral computed tomography (CCT) in order to compare the main reasons at referral to investigation with the CCT results and the costs with normal and abnormal CCT. It was also studied the age and sex of the patients. Data were collected from one out of three diagnostic centers in Salvador, Brasil, for a three years period. The 2860 CCT exclude all investigation carried out for the follow-up of a previously diagnosed abnormality. CCT abnormalities were detected in 1152 (40.3%). The following reasons showed the highest proportion of abnormal CCT, for males and females respectively: demential syndrome (91.7 and 83.3%); cerebrovascular accidents (85.1 and 73.6%); infectious and parasitary diseases (76.5 and 78.6%); tumors (65.8 and 55.4%); and head injuries, 63.6% for males. In the female group, 65.0% of the CCT were normal, in a range of 65.0 to 80.0% for the age groups under 54 years old. In the male group, the highest proportion of normal CCT was found in the age groups: 25-34 (68.4%), < 15 (62.9%) and 35-44 (62.7%). The most common reasons for normal CCT for males and females were: headache (81.3 and 87.5%); dizziness/vertigo (79.3 and 78.6%); seizures (67.3 and 70.0%); psychomotor deficiency (72.0 and 67.7%) and "endocrine disorders", 75.0% for each sex. The highest proportion of normal CCT (65.3%) was requested by medical "convenios". The cost with normal CCT reached US$565,225 and with the abnormal ones, US$381,247. Costs with normal CCT were 2.2 higher for medical "convenios" as compared to those of the National Institute of Security requests and 2.8 more than those of private medicine.
