Recaídas del trastorno de espectro de la neuromielitis óptica e influencia estacional en una cohorte de un país ecuatorial / Neuromyelitis optica spectrum disorders relapses and seasonal influence in an equatorial country cohort

Introducción La evidencia sobre la distribución estacional de las recaídas del trastorno del espectro de la neuromielitis óptica (NMOSD), especialmente en países tropicales, es limitada y diversa. Objetivo Evaluar la influencia de las variaciones estacionales en las recaídas del NMOSD en un país localizado sobre la línea ecuatorial. Pacientes y métodos Se llevó a cabo un estudio ecológico, con información retrospectiva de una cohorte de pacientes con NMOSD atendida entre enero de 2003 y diciembre de 2020 en Medellín, Colombia. Se recolectaron datos demográficos y clínicos de los pacientes, así como información sobre variables estacionales y climáticas. Se calculó la frecuencia de recaídas por estación, mes y año, y se realizó una regresión binomial negativa para evaluar la asociación entre el número de recaídas, y las variables estacionales y climáticas. Resultados Se incluyó a 113 pacientes, de los cuales el 89,38% eran mujeres, con una edad media en el momento del diagnóstico de NMOSD de 44,97 (±13,98) años y una mediana de tres recaídas (rango intercuartílico: 1-2). Se registraron 237 recaídas, la mayoría en pacientes seropositivos para anticuerpos antiacuaporina 4 (87,76%) y con mielitis longitudinal extensa como la presentación clínica más común (53,59%). Las recaídas se presentaron con mayor frecuencia durante la segunda temporada lluviosa (28,69%; n = 68), y en los meses de noviembre y diciembre. Sin embargo, en la regresión binomial negativa no se observó una asociación significativa entre el número de recaídas y las variables climáticas y estacionales, los meses y los años. Conclusión Las variables climáticas y los patrones estacionales no muestran una asociación significativa con cambios en el número de recaídas del NMOSD en pacientes residentes en un país localizado sobre la línea ecuatorial.

INTRODUCTION Information about seasonal distribution of Neuromyelitis optica spectrum disorders (NMOSD) attacks, particularly in tropical countries, has rarely been described and the reported data are diverse. OBJECTIVE. To evaluate influence of seasonal variation in NMOSD relapses in an equatorial country. PATIENTS AND METHODS Exploratory observational, retrospective ecological study in a cohort of patients with NMOSD followed from January 2008 to December 2019. Data of demographic, clinical information, characteristics of relapses and seasonal temporal variation were recorded. Also, the annual, monthly and intra-annual seasonal variation of relapses was quantified. A negative binomial regression was used to estimate the associations between the number of relapses and climatic and temporal variables. RESULTS One hundred thirteen patients were included, most of them were female (89.38%), with a mean age at NMOSD diagnosis was 44.97 (±13.98) and the median of relapses per patient were 2 relapses (IQR 1-3). The patients presented 237 relapses, most of these in AQP4 seropositive patients (87.76%) and longitudinal extensive myelitis was the most frequent type of relapse (53.59%). According to the temporal variation, relapses were more common in the second rainy season (28.69%) during November and December. However, there weren’t significant differences in the number of relapses between seasons and climatic variables in the multivariable model. CONCLUSION. The number of NMOSD relapses in this equatorial country cohort did not exhibit any significant associations with climatic variations, including changes in rainy or dry seasons. (AU)

Training Community African American and Hispanic/Latino/a Advocates on Prostate Cancer (PCa): a Multicultural and Bicoastal Approach.

African American communities are disproportionately impacted by prostate cancer (PCa) compared to other racial/ethnic groups. Whereas the incidence of PCa in Hispanic/Latino men is lower than the incidence in non-Hispanic/Latino White men, Hispanic/Latino men are more likely to be diagnosed with PCa in late stages, and less likely to be knowledgeable about PCa, resulting in significant disparities. We developed, culturally adapted, translated, implemented, and evaluated a PCa Cancer Advocacy Training in African American and Hispanic/Latino/a communities. Culturally and language specific content for African American and Hispanic/Latino/a patients on PCa causes, risk factors, epidemiology, detection, diagnosis, and treatment were delivered through a workshop and simultaneously broadcasted in Spanish in Los Angeles County (n = 29) and in English in Tallahassee, FL (n = 9). Pre- and posttest surveys assessed impact. Pre vs post differences were statistically significant in knowledge (5.0 ± 1.6 vs 6.3 ± 1.1) and advocacy intentions (3.9 ± 0.9 vs 4.3 ± 0.8), on correctly identifying warning signs for PCa (50% vs 87%), intent to inform and educate about PCa within the next 3 months (69% vs 95%), to ensure that high-quality research is sensitive to the priorities of patients (63% vs 84%), to help increase patient recruitment, compliance, and retention for clinical trials within the next month (62% vs 84%), intent to engage in PCa patient education within the next 3 months (67% vs 92%), and in engaging in PCa community outreach within the next 3 months (67% vs 94%). There were no significant differences due to race/ethnicity. The Cancer Advocacy Training led to increased knowledge, awareness, and intention to engage in advocacy regarding PCa in the next 3 months. Results suggest that delivering culturally and language specific educational information increases engagement of Hispanic/Latino/a and African American patient/community advocates.

Gender disparities in multiple sclerosis research and leadership: A Colombian perspective.

Background: The neurological academic field is an illustrative example of persistent gender-related disparities reflected in compensation, funding, leadership, promotion, publishing, and recognition. Several studies indicate that neurology is one of the most underrepresented specialties with female physicians as first authors, but also has one of the highest gender payment gaps. Neglecting the role of women in academic leadership positions hinders the visibility and recognition of research and leadership in multiple sclerosis (MS). Increasing diversity within academia has positive effects, such as widening focus and expanding the plurality of research outputs. The gender gap and visibility of female MS clinicians and researchers remains an unexplored research topic in our country despite the rising number of female neurologists. Objective: This study aims to establish the gender distribution between researchers and clinical neurologists in multiple sclerosis in Colombia and raise awareness about gender disparities in this area. Methods: We applied a cross-sectional survey study of Colombian neurologists and neurology residents currently members of the Colombian Neurology Association. Mean and standard deviation (SD) were used for quantitative variables and frequency for qualitative variables. To evaluate the influence of gender, logarithmic regression was used. Data were analyzed in SPSS 26. Results: A total of 201 participants agreed to complete the survey, most of whom were female (n = 135, 67.2%). All the Colombian regions were represented in the survey. Of those surveyed, 31.5% (n = 64) had an interest in demyelinating diseases and MS, of which 46.8% (n = 30) were female. Of the women with MS training, only 50% (n =5) had more than three publications as the first author of a scientific article compared to men (n = 5, 83%). After adjusting the number of publications by gender, there were no significant differences between men and women (median 2.0[2, 1.21] vs. 2[2, 0.5], p = 0.904). However, only 16.6% (n = 5) of women had a visible academic, leadership, or teaching position compared with men 75.7% (n = 25). When adjusting the salary income by gender, we found a statistically significant difference between women and men (median 2.0 [5, 1.47] vs. 3 [5, 1.65], p = 0.006). Women in MS earned between USD 2,500 and 3,800 per month; while men earned between USD 3,800 to 5,070. Conclusion: Despite a higher number of female neurologists trained in MS in Colombia, our data suggest considerable differences and gender gaps with regard to diverse opportunities at the academic, salary promotion, leadership, teaching, and recognition levels between male and female MS neurologists.

Down syndrome predisposes to haematological disorders. It is estimated that 5-30% of neonates with this condition will develop transient abnormal myelopoiesis. Treatment is not standardized; exchange transfusion and the use of cytarabine could be effective. We present two clinical cases of patients with Down syndrome, who during the neonatal period showed acute myeloid leukemia and transient abnormal myelopoiesis, the treatments used and their outcomes. Suspicion and early diagnosis of this entity are considered determining factors in prognosis.

Prevalence of neuromyelitis optica spectrum disorder in antioquia between 2016 and 2018.

BACKGROUND: There are few epidemiological studies published in the world evaluating the prevalence of Neuromyelitis Optica Spectrum Disorder (NMOSD). The true prevalence of the disease is not known and the studies carried out are based on the diagnostic criteria used prior to 2015. OBJECTIVE: To determine the prevalence of NMOSD in Antioquia, from January 2016 to December 2018. METHODS: The prevalence of NMOSD in Antioquia was determined using the Capture-Recapture Method. Eight centers in the Department of Antioquia for the care of patients with neurological diseases were included. The data was collected between 2016 and 2018. RESULTS: A total of 221 consultation histories, 169 patients with a diagnosis of NMOSD were identified. The prevalence was 4.03 cases/100,000 inhabitants (95% confidence interval (CI) 3.3-4.8) of whom (87.5%), were women and the predominant race was Mestizo (81.6%). The most frequent initial presentation was optic neuritis (ON) (50.9%). Most of the patients had motor or visual disability (86.4%) and the treatment most used was Rituximab (47.9%). CONCLUSION: The prevalence of NMOSD in Antioquia is one of the highest reported in the world, except for the French Antilles. More studies are required to know the prevalence of this disease in the Colombian population.

Pronóstico en pacientes con ataque cerebrovascular isquémico de circulación posterior / Functional outcome in posterior circulation acute ischemic stroke patients

RESUMEN INTRODUCCIÓN: El ochenta por ciento de los ataques cerebrovasculares son isquémicos, y uno de cada cinco afecta la circulación posterior. Su diagnóstico es difícil y los datos disponibles sobre el pronóstico y la mortalidad son discordantes. OBJETIVO: Evaluar el desenlace funcional a 180 días de los pacientes con ataque cerebrovascular (ACV) isquémico de circulación posterior (CP). MATERIALES Y MÉTODOS: Seguimiento prospectivo a pacientes con ACV de CP que ingresaron al Instituto Neurológico de Colombia entre septiembre del 2017 y septiembre del 2018. El desenlace clínico fue determinado mediante la escala Rankin modificada (mRS) al mes, a los seis meses y al año. RESULTADOS: Fueron incluidos 68 pacientes. La edad promedio fue 61 ±17 años y 60,3 % fueron hombres. El 85% tenía un mRS previo al ACV ≤ 1 y el 63 % un NIHSS basal ≤ 4. Nueve pacientes (13,2 %) recibieron terapia de reperfusión aguda (rtPA, TEV o ambas) y siete (10,3 %) adicionales arteriografía diferida. Dieciséis pacientes (23,5 %) presentaron una mejoría del NIHSS basal ≥ 4 puntos. Cuarenta y seis pacientes (74,2 %) presentaron un desenlace excelente mRS 0-1 a los seis meses y 87,1 % fueron categorizados mRS favorable (mRS 0-2). En el análisis ajustado, el NIHSS ≥ 4 fue un predictor de desenlace desfavorable a seis meses (RR 6,4; IC95 % 2,9-14,2). Seis pacientes (9,0 %) fallecieron, cuatro relacionados con el episodio actual o su recurencia. CONCLUSIONES: La mayoría de los pacientes con ACV de CP tienen desdenlaces favorables y una baja mor%talidad. La escala de NIHSS basal es un factor pronóstico independiente.

SUMMARY BACKGROUND: Ischemic strokes account for 80 % of all strokes, and one of every five compromises the posterior circulation. The diagnosis is difficult, and the data available about the outcome and mortality are discordant in the literature. OBJECTIVE: To investigate the clinicai outcome of patients at 180 days after posterior circulation ischemic stroke METHODS: Patients with diagnosis of posterior circulation stroke admitted to Instituto Neurológico de Colombia between September 2017 to 2018 were prospective included. The functional outcome by modified Rankin scale score (mRS) was determined at 1-month, 6-month, and 12-month after disease onset. RESULTS: 68 patients were included. The median age was 61 years ± 17 and 60.3 % were male. 85 % had a baseline mRS ≤ 1, and 63 % had a baseline National Institute Stroke Scale (NIHSS) ≤ 4. Nine patients were taken to acute recanalization therapies (rtPA, endovascular therapy or both) and seven more delayed arteriography. Sixteen patients (23.5 %) demonstrated an improvement of four or more points over the baseline NIHSS. Forty-six patients (74.2 %) had an excellent outcome 0-1 at six months and 87,1 % were categorized favorable mRS (mRS 0-2). In the adjusted analysis an NIHSS > 4 was a predictor of an unfavorable outcome at 6-month (RR 6.4; IC95 % 2.9-14.2). Six patients died (9 %); four of them in relation to the current event or an ischemic stroke recurrence. CONCLUSION: Most of the patients with posterior ischemic stroke have favorable outcomes and a low mortality. The baseline NIHSS is an independent prognostic risk factor.

Impact of a community-based intervention on Latino grandparents' knowledge about and self-efficacy in supporting grandchildren's physical activities.

INTRODUCTION: Latino grandparents are often involved in rearing grandchildren, but their roles in promoting children's physical activity (PA) have been largely overlooked. This study examined the impact of a community-based intervention called Nietos Activos y Saludables (Active and Healthy Grandchildren) on Latino grandparents' knowledge about and self-efficacy in supporting grandchildren's (aged 2-12 years) PA. METHOD: The Spanish language intervention, consisting of 4 weekly sessions, was delivered to 12 Latino grandparents (primarily female, aged > 60 years) in Los Angeles County from October to November 2017. Pre- and posttest surveys and postintervention focus groups assessed the intervention impact. RESULTS: Participants indicated that the intervention provided useful information. After intervention sessions, participants achieved a higher score in test on PA requirements for children. They also reported greater knowledge about children's PA, local resources for children's PA, and modifying children's behavior. Additionally, participants reported greater confidence in motivating children in PA and collaborating with parents in promoting children's PA. Results of focus groups generally confirmed the quantitative findings. DISCUSSION: Nietos Activos y Saludables intervention has the promise to increase Latino grandparents' knowledge about and self-efficacy in supporting grandchildren's PA. Future studies should test the impact of the intervention on grandparents' behavior and grandchildren's health outcomes using a randomized controlled trial.

Epidemiological characterization of diabetic patients on therapy with continuous subcutaneous insulin infusion and continuous glucose monitoring in real time.

OBJECTIVE: To describe baseline characteristics of diabetic patients who were started on insulin pump and real time continuous glucose monitor (CSII-rtCGM) in a specialized center in Medellin, Colombia. MATERIALS AND METHODS: All patients with diabetes with complete data who were started on CSII-rtCGM between February 2010 and May 2014 were included. This is a descriptive analysis of the sociodemographic and clinical characteristics. RESULTS: 141 of 174 patients attending the clinic were included. 90,1% had type 1diabetes (T1D). The average age of T1D patients at the beginning of therapy was 31,4 years (SD 14,1). 75.8% of patients had normal weight (BMI<25), 21.0% were overweight (BMI 25-30) and 2,3% were obese (BMI>30). The median duration of T1D was 13 years (P25-P75=10.7-22.0). 14,2% of the patients were admitted at least once in the year preceding the start of CSII-rtCGM because of diabetes related complications. Mean A1c was 8.6%±1.46%. The main reasons for starting CSII-rtCGM were: poor glycemic control (50.2%); frequent hypoglycemia, nocturnal hypoglycemia, hypoglycemia related to exercise, asymptomatic hypoglycemia (30.2%); severe hypoglycemia (16.44%) and dawn phenomena (3.1%). CONCLUSION: Baseline characteristics of patients included in this study who were started on CSII-rtCGM are similar to those reported in the literature. The Clinic starts CSII-rtCGM mainly in T1D patients with poor glycemic control, frequent or severe hypoglycemia despite being on basal/bolus therapy.

Factores sociales, culturales e históricos que influyeron en la perdida dental de adultos mayores. Valle de Aburra 2000 / Social, cultural and historic factors which influenced tooth loss in elder adults in The Aburra Valley, 2000

El propósito de este estudio fue explorar las causas de la perdida dental a partir de relacionados con el desarrollo de la comunidad, costumbres, hábitos, educación y experiencias de atención a través de la experiencia vivida por adultos mayores, permite describir diferentes factores socioculturales relacionados con la perdida dental, dentro del marco del desarrollo histórico de la odontología. Se recolectó la información mediante entrevistas informales, no estructuradas, e individuales. Las entrevistas se analizaron siguiendo el procedimiento de codificación abierta, determinación de categorías con muestreo teórico y codificación axial. Se obtuvo como categoría central: el dolor dental. El cual es la principal causa de perdida dental en los adultos mayores. Se concluye que no hay preocupación por la enfermedad bucal, sino por la presencia del dolor dental. Entre muchos intentos por curarlo y prevenirlo ha existido desde épocas remotas un tratamiento definitivo: la extracción dental. Se encontró cómo la urgente necesidad de curarlo en un medio carente de recursos, conducía a la pérdida dental. La influencia familiar y la moda difundieron un pensamiento “sacarse los dientes es lo mejor”. Concepto difundido por generaciones. El enfoque de la prevención odontológica debe fundamentarse en el conocimiento popular.
