Factors associated with cognitive impairment in Latin American older adults: A cross-sectional observational study of COVID-19 confinement.

INTRODUCTION: The effects of COVID-19 confinement have been severe, especially in older adults. Therefore, we analyzed the factors associated with cognitive impairment (CI) in Latin America (LA). METHODS: We conducted a cross-sectional observational study with a total of 5245 older adults from 10 countries in LA. Measurement: We used the Telephone Montreal Cognitive Assessment (T-MoCA) and the Eight-item Informant Interview to Differentiate Aging and Dementia (AD8) scale. RESULTS: We found that age, depressive symptomatology, bone fractures, being widowed, having a family member with dementia, and unemployment were associated with an increased risk of CI. In contrast, higher education, hypertension with continuous treatment, quarantine, and keeping stimulating cognitive and physical activities were associated with a lower probability of CI. No significant association was found between suffering from diabetes or being retired and CI. DISCUSSION: It is essential to conduct follow-up studies on these factors, considering their relationship with CI and the duration of confinement.

Viral-associated trichodysplasia secondary to antineoplastic treatment in a patient with lymphoblastic leukemia.

Viral-associated trichodysplasia spinulosa is an unusual condition with distinctive clinical and histopathological features. Initially described in patients immunosupressed as a result of solid organ transplantation, it has also been reported in patients treated with immunosuppressive drugs other than cyclosporine or being treated for hematological malignancies. Patients presented with disseminated follicular, hyperkeratotic papules, and variable degrees of alopecia. Histopathological examination revealed shaftless bulbous and dilated hair follicles with keratotic plugging of the infundibulum. The authors reported a case of viral-associated trichodysplasia in a 5-year-old boy treated for a lymphoblastic leukemia. Eruption persisted, although treated with emollients and keratolytics, but resolved spontaneously after completing the antineoplastic medication.

Elastolytic giant cell granuloma: clinic-pathologic review of twenty cases.

BACKGROUND: O'Brien described four histopathological patterns of actinic granuloma (AG). Since then, only single cases and a few series have been reported in the literature, most corresponding to cases of the giant cell type. METHODS: We reviewed all the cases diagnosed as AG or elastolytic giant cell granuloma (EGCG) in our department from 1988 until 2010. The biopsies were classified into the four patterns previously described. RESULTS: Giant cell pattern was found to be the most frequent (70% of the cases). In four cases, the biopsies showed more than one histopathologic pattern. All the lesions were located on sun-exposed areas or were related to chronic heat exposure. Diabetes mellitus was associated in 40 % of the cases. CONCLUSIONS: The giant cell pattern of EGCG is the most frequent. Some cases may share histopathologic features of more than one variant and thus, we consider they may be categorized as mixed patterns. Diabetes mellitus is the most common associated disease and should always be ruled out.

Therapeutic inertia in the outpatient management of dyslipidemia in patients with ischemic heart disease. The inertia study.

INTRODUCTION AND OBJECTIVES: Studies indicate that dyslipidemia is undertreated. Numerous systematic reviews have shown that, even when therapeutic targets set by clinical practice guidelines have not been met, treatment remains unchanged despite the availability of alternatives approaches. The result is increased morbidity and mortality. Our aims were to investigate this phenomenon, known as therapeutic inertia, in patients with dyslipidemia and ischemic heart disease, and to determine its possible causes. DESIGN: national, multicenter, observational study of data obtained from physicians by questionnaire and from the clinical records of patients with ischemic heart disease. Main variable: therapeutic inertia during a consultation, defined as treatment remaining the same despite a change being indicated (e.g. low-density lipoprotein cholesterol >100 mg/dl or >70 mg/dl in diabetics). Covariates: physician, patient and consultation characteristics. STATISTICAL ANALYSIS: multivariate logistic regression analysis of factors associated with therapeutic inertia during a consultation. RESULTS: Overall, 43% of consultations involved therapeutic inertia, and an association with coronary risk factors, including diabetes, did not result in a change in treatment. Therapeutic inertia occurred more frequently when there was a long time between the diagnosis and treatment of dyslipidemia and that of ischemic heart disease. Undertreatment was particularly common in women despite a greater overall risk. The more experienced physicians treated younger patients more appropriately. Clinical practice was improved by educational sessions at conferences. CONCLUSIONS: Therapeutic inertia was common in patients with chronic ischemic heart disease and dyslipidemia, irrespective of overall cardiovascular risk. Factors associated with the patient, disease and physician had an influence.
