Normative data for tests of visuo-spatial, visuo-constructional skills, and visual memory for Spanish-speaking adults in the United States.

BACKGROUND: The Rey-Osterrieth Complex Figure Test (ROCFT) and the Clock Drawing Test (CDT) are commonly used in clinical practice. The ROCFT measures constructional praxis, visual perception, and visuospatial learning and memory, and the CDT assesses for visuospatial, constructional, and executive difficulties. Several neurological disorders are associated with visuospatial and visuo-constructional impairments, yet reliable normative data accounting for sociodemographic and acculturative variables are scarce for Hispanics living in the U.S. OBJECTIVE: To generate normative data for the ROCFT and CDT in a Spanish-speaking adult population living in the U.S. METHODS: The sample consisted of 245 cognitively healthy normal adults recruited from several states in the U.S. Each participant was administered the ROCFT and CDT as part of a larger cognitive battery. The ROCFT and CDT were normed using a Bayesian approach. Age, age2, education, sex, acculturation, and language proficiency were included as predictors in the analyses. RESULTS: ROCFT performance was associated with education and age, particularly as they interacted with Spanish language proficiency and time spent in the U.S. Education was significantly associated with recall abilities and a lower memory recall on the ROCFT. Age was found to vary depending on a person's bilingual abilities. Sex did not emerge as a predictor of performance, and it did not interact significantly with other variables. CONCLUSION: This is the first study to include acculturation and language proficiency variables in the creation of norms for the assessment of visuo-constructional abilities. This study will have a large impact on the practice of neuropsychology in the U.S.

WHO-UCLA auditory verbal learning test: Normative data for Spanish-speaking adults in the United States.

BACKGROUND: Hispanics are a significant demographic in the U.S., with diverse cultures and languages. Assessing cognition in this group is complex as cultural and linguistic factors have been found to affect test performance. OBJECTIVE: To generate normative data on the World Health Organization-University of California Los Angeles Auditory Verbal Learning Test (WHO-UCLA AVLT) in a sample of Spanish-speaking Hispanics residing in the U.S. METHODS: The sample included 245 Spanish-speaking individuals aged 18-80 across the U.S. (California, Connecticut, Florida, Indiana, New Jersey, Oregon, Virginia, and Wisconsin). Participants were administered the WHO-UCLA AVLT as part of a comprehensive neuropsychological battery. A Bayesian regression approach was used to estimate normative data, including covariates found to be important for predicting performances on measures of learning and memory. RESULTS: Bayesian models showed a logarithmic link between education and all WHO-UCLA AVLT trials, except recognition. For delayed recall, increased Spanish proficiency benefited women's performance exclusively. Time in the U.S. was a significant predictor for total recall, indicating worse performance with longer residency. CONCLUSION: Recognizing cultural factors like language proficiency and duration of U.S. residence is essential for accurately evaluating cognitive function among Spanish-speaking Hispanics. This research emphasizes the importance of accounting for cultural nuances in developing norms for neuropsychological assessments, thereby improving their relevance and effectiveness in diverse communities.

A preliminary examination of the TOMM2 in a sample of Spanish speakers in the United States.

BACKGROUND: The Test of Memory Malingering (TOMM) is a widely used performance validity measure that is available in both English and Spanish. The Spanish version, however, has historically lacked normative data from samples that are representative of the U.S. Hispanic/Spanish speaking population. OBJECTIVE: The aim of the current study was to collect normative data on the update TOMM 2 for Hispanic individuals residing in the U.S. METHODS: Normative data on the TOMM 2 was collected across 9 sites from different regions of the U.S. The total sample consisted of n = 188 cognitively healthy adults aged 18 and over with no current or prior history of neurological or psychiatric disorder. Descriptive analyses were performed on total raw scores. RESULTS: Participants obtained a mean score of 48.15 (SD = 2.81) on trial 1 of the TOMM 2, 49.86 (SD = 0.487) on trial 2, and 49.84 (SD = 0.509) on the recognition trial. Scores are provided for traditional cutoff scores as well as some popular cutoffs reported in the literature. Item level analyses were conducted as well as evaluation of performance based on a variety of demographics. CONCLUSION: When compared to the English-speaking normative sample used for the original TOMM, this sample demonstrated better performance on the TOMM 2 indicating better cultural appropriateness of the items. This is the first study conducted that provides culturally appropriate descriptive norms for use with Spanish speakers living in the U.S.

Executive function tests: Normative data for Spanish-speaking adults in the United States.

BACKGROUND: Normative data for Spanish-speaking populations, particularly Hispanics in the U.S., is notably scarce. OBJECTIVE: This study aims to establish normative data for executive function tests (Modified Wisconsin Card Sorting Test and Stroop Color and Word Test) among Spanish-speaking Hispanics in the U.S. METHODS: We assessed 245 individuals aged 18-80 from eight U.S. states (California, Connecticut, Florida, Indiana, New Jersey, Oregon, Virginia, and Wisconsin) and employed Bayesian regression to estimate norms, considering various sociodemographic factors influencing performance. RESULTS: The posterior distribution suggests a high probability that age impacts SCWT performance, with older adults likely to show greater declines, particularly among those with high proficiency in Spanish. The posterior distribution suggests a stronger effect of age on M-WCST performance among individuals with longer U.S. residency. Educational attainment demonstrates a robust positive impact on M-WCST outcomes, with lower levels of education associated with a higher probability of increased errors. An interaction between education and Spanish proficiency was observed, influencing SCWT scores differently across proficiency levels. Sex and acculturation levels interact to affect SCWT performance, with distinct patterns observed between men and women. This suggests that the impact of acculturation on cognitive test performance may vary by gender. CONCLUSION: Establishing culturally sensitive normative data can enhance accurate identification of executive dysfunction and reduce misdiagnosis risks. This study underscores the importance of considering sociocultural factors including acculturation and language proficiency in neuropsychological assessments to better serve diverse populations.

Normative data for verbal fluency and naming tests in Spanish-speaking adults in the United States.

BACKGROUND: Linguistic deficits are common across neurological and neurodegenerative disorders. Currently there are limited neuropsychological norms available for Spanish-speaking adults residing in the U.S. OBJECTIVE: To generate norms for two verbal fluency tests and the Boston Naming Test (BNT) in a Spanish-speaking population in the U.S., with adjustments for demographic and cultural variables. METHODS: The sample consisted of 245 adults from the U.S. Participants completed phonological and semantic verbal fluency tests and the BNT. A standardized two-step statistical procedure was used. RESULTS: For the phoneme F, interactions between Spanish proficiency, age, and education arose. Better performance on phonemes A, S, and M was related to education. Spanish proficiency, acculturation, and time in the U.S. were associated with the phonemes S, A, P, M, and R. An age by education interaction was found for phonemes M and R. The FAS and PMR triads were related to age, sex, time in U.S., and Spanish proficiency. For the semantic verbal fluency tests, an interaction between education and Spanish proficiency arose. For the BNT, test scores were related to education, and significant interactions were also found based on education's interaction with Spanish proficiency and acculturation. CONCLUSION: This study highlights the importance of accounting for sociodemographic and acculturative factors when developing normative data for verbal fluency tests and the BNT for dominant Spanish-speaking adults in the U.S. These sociodemographically-adjusted norms will help improve accuracy of diagnosis and interpretation of linguistic test performance in Spanish speakers living in the U.S.

Methods in Stroke Prevention in the Wisconsin Native American Population.

Native American individuals are more frequently affected by cerebrovascular diseases including stroke and vascular cognitive decline. The aim of this study was to determine stroke risk factors that are most prevalent in Wisconsin Native Americans and to examine how education at the community and individual level as well as intensive health wellness coaching may influence modification of stroke risk factors. Additionally, we will investigate the role novel stroke biomarkers may play in stroke risk in this population. This paper details the aims and methods employed in the "Stroke Prevention in the Wisconsin Native American Population" (clinicaltrials.gov identifier: NCT04382963) study including participant health assessments, clinical ultrasound exam of the carotid arteries, cognitive testing battery, and structure and execution of the coaching program.

Trajectories of life satisfaction in Hispanic individuals over the 10 years after traumatic brain injury: A model systems study.

PURPOSE: To identify life satisfaction trajectories at 1-10 years post-traumatic brain injury (TBI) and examine which demographic and injury characteristics at the time of injury are associated with those trajectories. METHODS: Participants included 1,051 Hispanic individuals from the multi-site, longitudinal TBI Model Systems (TBIMS) database. Individuals were enrolled after sustaining a TBI and while undergoing inpatient rehabilitation at a TBIMS site; they were included if they completed the Satisfaction with Life Scale during one or more follow-up data collections at 1, 2, 5, or 10 years after TBI. RESULTS: A linear (straight-line) movement of life satisfaction trajectories was the best fit to the data. Across the overall sample, life satisfaction increased over time, with higher trajectories for Hispanic individuals who had been partnered at baseline, born outside the US and experienced a nonviolent injury cause. There were no significant interactions between time and any of these main effect predictors, suggesting no differential change over time in life satisfaction trajectories as a function of these characteristics. CONCLUSIONS: Results revealed increases in life satisfaction over time among Hispanic individuals with TBI and shed light on critical risks and protective factors that may inform targeted rehabilitation services with this underserved group.

Focus on today's evidence while keeping an eye on the future: lessons derived from hypertension in women.

While evidence-based medicine has contributed enormously to the uniformity and rationale of patient care, it is necessary that we anticipate changes in order to implement their rapid translation to practice. The purpose of this review is to expose three issues regarding cardiovascular health in women, including milestones to reflect the pace at which these are incorporated into public policies. Two of these matters, as changes in the thresholds of normal blood pressure in gestation and in nonpregnant women, need further evidence and deserve to be retrospectively analyzed in high-quality databases. The third subject derives from the association of remote cardiovascular complications of hypertensive pregnancies, an example of the unnecessary delay of more than two decades to install a wide prevention strategy when the health system is not on the watch.

Clinical Presentation and Perioperative Management of Pheochromocytomas and Paragangliomas: A 4-Decade Experience.

PURPOSE: Latin American reports on pheochromocytomas and paragangliomas (PPGLs) are scarce. Recent studies demonstrate changes in clinical presentation and management of these patients. Herein, we assessed the main characteristics of PPGL patients in our academic center over the past 4 decades. METHODS: Demographic, clinical, biochemical, and perioperative data from 105 PPGL patients were retrospectively and prospectively collected over the 1980-2019 period. Data were organized into 4 periods by decade. RESULTS: Age at diagnosis, gender, tumor size and percentage of bilaterality, percentage of paragangliomas, and metastases remained stable across the 4 decades. The proportion of genetic testing and incidentalomas increased in recent decades (all P < 0.001). Therefore, we compared PPGLs diagnosed as incidentalomas (36%) with those clinically suspected (64%). Incidentalomas had fewer adrenergic symptoms (38 vs. 62%; P < 0.001) and lower rates of hypertension (64% vs. 80%; P = 0.01) and hypertensive crisis (28% vs. 44%; P = 0.02); also, they had lower functionality (79% vs. 100%; P = 0.01) and lower catecholamines levels (8.4-fold vs. 12.5-fold above upper cutoffs; P = 0.04). Regarding management of all PPGLs over the decades, we observed significant increases in both perioperative doxazosin dose (P = 0.003) and laparoscopic approach rates (P < 0.001), along with a decrease in the length of hospital stays (P = 0.007). CONCLUSIONS: We observed a change in the clinical presentation of PPGL in recent decades, with a marked increase in incidental cases and milder symptoms. The implementation of a multidisciplinary program for adrenal disorders in our institution has translated into more timely diagnoses, more genetic testing, and improvements in perioperative management.

[A secondary focal segmental glomerulosclerosis due to prematurity]. / Glomeruloesclerosis focal y segmentaria secundaria a la oligonefronia del prematuro.

INTRODUCTION: Both premature birth and low birth weight compromise nephron development. The lower nephron endowment is subjected to compensatory hyperfiltration that overloads the glomeruli and leads to the vicious circle of progressive deterioration of renal function. OBJECTIVE: To emphasize the risk of renal involvement in this susceptible population by describing the case of a patient with long-term follow-up. CLINICAL CASE: Low-weight premature newborn, who presented at 3 years of age severe hypertension, which was controlled with different types of antihypertensive drugs. However, 10 years later subnephrotic proteinuria was detected; a renal biopsy confirmed a focal and segmental glome rulosclerosis. Despite blocking the renin-angiotensin system for 23 years, his renal function progres sively deteriorated, until requiring chronic hemodialysis during the last 3 years. CONCLUSION: It is essential to increase the awareness of the risk of renal damage in premature and low weight newborns in order to establish management that covers from gestation to adult life and to achieve an individual and epidemiological impact on renal health.

Bradykinin Exerts Independent Effects on Trophoblast Invasion and Blood Pressure in Pregnant Guinea Pigs.

INTRODUCTION: The pleiotropic kininogen-kallikrein-kinin system is upregulated in pregnancy and localizes in the uteroplacental unit. To identify the systemic and local participation of the bradykinin type 2 receptor (B2R), this was antagonized by Bradyzide (BDZ) during 2 periods: from days 20 to 34 and from days 20 to 60 in pregnant guinea pigs. METHODS: Pregnant guinea pigs received subcutaneous infusions of saline or BDZ from gestational day 20 until sacrifice on day 34 (Short B2R Antagonism [SH-B2RA]) or on day 60 (Prolonged B2R Antagonism [PR-B2RA]). In SH-BDZA, systolic blood pressure was determined on day 34, while in PR-BDZA it was measured preconceptionally, at days 40 and 60. On gestational day 60, plasma creatinine, uricemia, proteinuria, fetal, placental and maternal kidney weight, and the extent of trophoblast invasion were evaluated. RESULTS: The SH-B2RA increased systolic blood pressure on day 34 and reduced trophoblast myometrial invasion, spiral artery remodeling, and placental sufficiency. The PR-B2RA suppressed the normal blood pressure fall observed on days 40 and 60; vascular transformation, placental efficiency, urinary protein, serum creatinine, and uric acid did not differ between the groups. The proportion of all studied mothers with lost fetuses was greater under BDZ infusion than in controls. CONCLUSION: The increased systolic blood pressure and transient reduction in trophoblast invasion and fetal/placental weight in the SH-B2R blockade and the isolated impact on blood pressure in the PR-B2R blockade indicate that bradykinin independently modulates systemic hemodynamics and the uteroplacental unit through cognate vascular and local B2R receptors.

Preeclampsia and cardiovascular disease: interconnected paths that enable detection of the subclinical stages of obstetric and cardiovascular diseases.

The potent and now longstanding evidence of the association between placentation-related disorders and cardiovascular disease should be translated into clinical practice in order to introduce a preventive approach to future obstetric and cardiovascular diseases. The purpose of this review is to integrate cardiovascular risk/disease and obstetric complications, which are linked by endothelial dysfunction, as windows of opportunity for improving women's health. Questionnaires adaptable to local practices are proposed to incorporate cardiovascular and obstetrical indexes into two stages of a woman's lifetime.

[Declaration of the Chilean Academy of Medicine of Law 20.850 "On clinical trials of pharmaceutical products and medical devices" and of the bylaw that will regulate its application]. / Declaración de la Academia Chilena de Medicina sobre el Título V de la Ley 20.850 (Ley Ricarte Soto) y su proyecto de reglamento "De los ensayos clínicos de productos farmacéuticos y elementos de uso médico".

In Chile, high cost treatments required by selected medical conditions are financed by the State, according to Law 20.850. A bylaw under discussion by the Senate regulates clinical trials, posing complex issues that will endanger local interest in front-line research: 1) The exclusive and mandatory control bestowed to the Institute of Public Health during all stages of the trials and also the surveillance of institutions performing clinical trials, overriding their Clinical Research Review Boards; 2) The 10 year period during which any adverse event is assumed to have been caused by the medication or devise evaluated by the trial, unless the contrary is proven in a judicial process; 3) Individuals submitted to the trials are entitled to free post trial access to the treatment received during the study, financed by the trial supporting entities and as long as the drug or devise is considered to be useful. While agreeing with the need to have a National Registry of Clinical Trials, we predict that the mentioned critical issues in the bylaw will lead to difficulties and unnecessary judicial processes, thus limiting clinicians' interest in performing research. We propose to modify the bylaw, excluding responsibilities on events associated with the natural evolution of the medical condition, with patients' ageing or with comorbidities and clinical events considered unpredictable when the protocol was accepted. We recommend that the free post trial access should be a joint decision involving the patient and the attending physician, taking in consideration that the volunteer has been exposed to risks and burdens, or when discontinuation of treatment entails a vital risk until the treatment under study has been approved and becomes available in the national market.

Este artigo tem por objetivo analisar a expansão da influência da China na América Latina nos campos econômico e militar bem como os Estados Unidos reagiu a este. Pois será utilizada a metodologia do estudo de caso-Venezuela, Bolívia e Equador, já que é onde a China tem uma forte presença e, especialmente, porque são países, como a potência asiática, têm um anti-política americano ou soberanista que busca consolidar uma ordem mundial multipolar A principal constatação é que a China não representa uma séria ameaça para os EUA no curto prazo, e de fato, a expansão da sua influência na região tem sido percebida pelo governo dos EUA como uma oportunidade. Isto é devido a várias razões: China tem implementado uma política cautelosa e pragmática que visa consolidar as suas metas nacionais sem desafiar diretamente a hegemonia dos EUA na região, reforçada por restrições internas que levam a liderança chinesa a optar por uma atitude menos ativista na atitude reorganização político-militar do mundo. Por outro lado, graças aos Estados Unidos, que está em uma fase de declínio de sua hegemonia na região, preferem promover os seus interesses em um quadro de cooperação e não de confronto, na esperança de tirar proveito desta nova situação.
