MONTREAL Cognitive Assessment , *MILD cognitive impairment , *POSTMENOPAUSE , *BODY mass index , *HORMONE therapy - Abstract
• This study examined the link between type of menopause and mild cognitive impairment (MCI) in nine Latin American countries. • A total of 1185 postmenopausal women (average age of 55.3 years) were assessed for MCI using the MoCA tool. • The study revealed that women with menopause before age 40 have no increased MCI risk, while those with surgical menopause, independent of age, are more prone to cognitive decline. • The study found that women who had ever used menopausal hormone therapy (MHT) had a lower risk of developing MCI. To evaluate the association between type of menopause (spontaneous or surgical) and mild cognitive impairment (MCI). This study was a cross-sectional, observational, and sub-analytical investigation conducted within gynecological consultations across nine Latin American countries. We assessed sociodemographic, clinical, and anthropometric data, family history of dementia, and the presence of MCI using the Montreal Cognitive Assessment (MoCA) tool. The study involved 1185 postmenopausal women with a mean age of 55.3 years and a body mass index of 26.4 kg/m2. They had an average of 13.3 years of education, and 37 % were homemakers. Three hundred ninety-nine experienced menopause before 40, including 136 with surgical menopause (bilateral oophorectomy). Out of the 786 women who experienced menopause at 40 or more years, 110 did so due to bilateral oophorectomy. There were no differences in MoCA scores among women who experienced menopause before or after the age of 40. However, lower MoCA scores were observed in women with surgical menopause than in those with spontaneous menopause (23.8 ± 4.9 vs. 25.0 ± 4.3 points, respectively, p < 0.001). Our logistic regression model with clustering of patients within countries found a significant association between MCI and surgical menopause (OR 1.47, 95 % CI: 1.01–2.16), use (ever) of menopausal hormone therapy (OR 0.33, 95 % CI: 0.21–0.50), and having >12 years of education (OR 0.21, 95 % CI: 0.14–0.30). When comparing women who experience spontaneous menopause over the age of 40 with those who undergo it before this age, there was no observed increased risk of developing MCI, while those with surgical menopause, independent of age, are more prone to cognitive decline. Women who have ever used menopausal hormone therapy have a lower MCI risk. Further research is warranted to delve deeper into this topic. [ABSTRACT FROM AUTHOR]

De tres cepas de Microsporum canis provenientes de pacientes con Tinea capitis se extrajeron macroconidias que fueron expuestas durante 13 días consecutivos a concentraciones crecientes de ajoene, entre 1 y 300 μM, usando el método de microdilución en placa CLSI M38-A2. Las estructuras fueron evaluadas morfométricamente para observar el efecto de este compuesto sobre el hongo. La comparación entre las conidias normales y las expuestas mostraron diferencias morfológicas. Los efectos in vitro de ajoene fueron tiempo dependiente, capaces de provocar en los fragmoconidios cambios morfológicos drásticos e irreversibles, evidenciados en el notable aumento del espesor de la membrana citoplasmática y en la pérdida de la proporción de los espacios interseptales de las conidias. El ajoene, como agente antimicótico, inhibió el crecimiento conidial, reconocido en microscopia por la deformación de la arquitectura normal de las células. La pérdida de la funcionalidad y viabilidad de las conidias, que se tornaron irregularares, probablemente se encuentran asociadas a alteración de la síntesis de la membrana plasmática e interconidial. From three strains of Microsporum canis isolated from patients with Tinea capitis, macroconidia were extracted. These were exposed during 13 cosecutive days to growing concentrations of ajoene, between 1-300μM, using the microdilution method in plate M38-A2. The structures were monitored morphometrically to observe the effect of this compound on the fungus. The comparison between the normal conidia and those exposed to the compound showed morphologic diferences. The in vitro effects were time dependent, able to induce drastic and irreversible morphologic changes in the fragmoconidia, evidenced in the noticeable increase of thickness of cytoplasmic membrane and in the loss of proportion of the interceptal spaces of conidia. Ajoene, as antimicotic agent, inhibited conidial growth, which is evidenced under the microscope by the deformation of the normal architecture of cells. The loss of function and viability of conidia, which became irregular, is probably associated to alteration of the synthesis of plasmic and interconidial membrane.

- Abstract
Objective: To assess the age at menopause (AM) in Latin America urban areas., Design: A total of 17,150 healthy women, aged 40 to 59 years, accompanying patients to healthcare centers in 47 cities of 15 Latin American countries, were surveyed regarding their age, educational level, healthcare coverage, history of gynecological surgery, smoking habit, presence of menses, and the use of contraception or hormone therapy at menopause. The AM was calculated using logit analysis., Results: The mean age of the entire sample was 49.4 +/- 5.5 years. Mean educational level was 9.9 +/- 4.5 years, and the use of hormone therapy and oral contraception was 22.1% and 7.9%, respectively. The median AM of women in all centers was 48.6 years, ranging from 43.8 years in Asuncion (Paraguay) to 53 years in Cartagena de Indias (Colombia). Logistic regression analysis determined that women aged 49 living in cities at 2,000 meters or more above sea level (OR = 2.0, 95% CI: 1.4-2.9, P < 0.001) and those with lower educational level (OR = 1.9, 95% CI: 1.3-2.8, P < 0.001) or living in countries with low gross national product (OR = 2.1, 95% CI: 1.5-2.9, P < 0.001) were more prone to an earlier onset of menopause., Conclusions: The AM varies widely in Latin America. Lower income and related poverty conditions influence the onset of menopause.
