Comparing transcervical balloon with osmotic dilators for cervical preparation prior to procedural abortion: A noninferiority randomized trial.

OBJECTIVES: This study aimed to compare cervical preparation with transcervical balloon to osmotic dilators for second-trimester procedural abortions. STUDY DESIGN: We performed an unblinded, randomized, noninferiority trial of people undergoing second-trimester procedural abortion at 18 + 0 to 23 + 6 weeks' gestation. We randomized participants to either overnight osmotic dilators (Dilapan-S) or transcervical balloon (Foley). Both groups received overnight mifepristone and preprocedural misoprostol. We powered the study on mean difference in procedure duration, a noninferiority limit of 5 minutes. We compared preprocedure cervical dilation and the need for additional dilation and, using a 100-point visual analog scale, measured physician satisfaction and ease of procedure, and participant pain and satisfaction. RESULTS: We recruited 32 participants at a single academic center. Although procedure time (minutes) was similar (balloon: 22.6 ± 8.9 vs Dilapan-S: 22.4 ± 12.8, p = 0.96), noninferiority was not met (mean difference, 0.2 minutes; 95% CI, -7.8 to 8.2). Cervical dilation >2 cm was more likely after Dilapan-S (100% vs 62.5%, p = 0.02). Placement was well tolerated with similar time (minutes) for insertion (balloon: 4.8 ± 1.0, Dilapan-S: 5.1 ± 2.3, p = 0.64) and maximum pain (median) with insertion (balloon 39 [5-78], Dilapan-S: 39 [0-100], p = 0.92). Pain immediately postinsertion was higher for Dilapan-S (33 [0-100] vs 18 [0-50], p = 0.046) and similar for maximum pain overnight, participant satisfaction, and likelihood to recommend. Complications were minor and similar between groups (p = 0.60). CONCLUSION: While significantly more people with transcervical balloon required mechanical dilation, the difference in operative time was clinically negligible. The transcervical balloon was well tolerated and acceptable by participants. IMPLICATIONS: Clinicians experienced in mechanical dilation may consider a transcervical balloon as a lower-cost tool for second-trimester abortion cervical preparation.

Remimazolam: ¿el agente ideal para sedación, inducción y mantenimiento de la anestesia? / Remimazolam: the ideal agent for sedation, induction and maintenance of anesthesia?

Resumen: El remimazolam es una nueva benzodiacepina que combina las propiedades farmacológicas de dos agentes utilizados en la anestesia: el efecto hipnótico del midazolam y el metabolismo del remifentanilo. El remimazolam se hidroliza por esterasas tisulares inespecíficas a metabolitos inactivos, permitiendo una alta depuración y recuperación rápida. Por sus propiedades farmacológicas, se ha propuesto su uso como un agente de acción ultracorta en procedimientos de sedación fuera de quirófano, inducción, mantenimiento de la anestesia y de sedación en la unidad de terapia intensiva. El perfil de seguridad del remimazolam es amplio, ya que sus efectos hemodinámicos y cardiorrespiratorios son menos marcados que otros fármacos empleados en dichos procedimientos. Como otras benzodiacepinas, los efectos del remimazolam pueden ser revertidos con flumazenil. Hasta el momento, el remimazolam ha demostrado ser un agente hipnótico eficaz; sin embargo, se requiere mayor investigación para establecer su utilidad clínica.

Abstract: Remimazolam is a new benzodiacepine that combines the pharmacological properties of two agents used in anesthesia: the hypnotic effect of midazolam and the metabolism of remifentanyl. Remimazolam is hydrolized by nonspecific tissue esterases into inactive metabolytes, allowing high clearance and fast recovery. Due to its pharmacological characteristics, it has been proposed as an ultra- short acting agent for sedation out operating room, induction and maintenance of anesthesia, as well as for sedation in the Intensive Care Unit. Remimazolam has an elevated safety profile, as it might that, it has less pronounced hemodynamic and cardiorespiratory effects in contrast to other drugs used in the same procedures. Like other benzodiacepines, remimazolam effects can be reversed with flumazenil. Remimazolam has proven to be an effective hypnotic agent, however further research and clinical evaluation is required to establish its use.

Red Blood Cell Transfusion in Patients With Placenta Accreta Spectrum: A Systematic Review and Meta-analysis.

OBJECTIVE: To evaluate red blood cell use during delivery in patients with placenta accreta spectrum. DATA SOURCES: We searched MEDLINE, EMBASE, CINAHL, Cochrane Central, ClinicalTrials.gov, and Scopus for clinical trials and observational studies published between 2000 and 2021 in countries with developed economies. METHODS OF STUDY SELECTION: Abstracts (n=4,275) and full-text studies (n=599) were identified and reviewed by two independent reviewers. Data on transfused red blood cells were included from studies reporting means and SDs, medians with interquartile ranges, or individual patient data. The primary outcome was the weighted mean number of units of red blood cells transfused per patient. Between-study heterogeneity was assessed with an I2 statistic. Secondary analyses included red blood cell usage by placenta accreta subtype. TABULATION, INTEGRATION, AND RESULTS: Of the 599 full-text studies identified, 20 met criteria for inclusion in the systematic review, comprising 1,091 cases of placenta accreta spectrum. The number of units of red blood cells transfused was inconsistently described across studies, with five studies (25.0%) reporting means, 11 (55.0%) reporting medians, and four (20.0%) reporting individual patient data. The weighted mean number of units transfused was 5.19 (95% CI 4.12-6.26) per patient. Heterogeneity was high across studies (I2=91%). In a sensitivity analysis of five studies reporting mean data, the mean number of units transfused was 6.61 (95% CI 4.73-8.48; n=220 patients). Further quantification of units transfused by placenta accreta subtype was limited due to methodologic inconsistencies between studies and small cohort sizes. CONCLUSION: Based on the upper limit of the CI in our main analysis and the high study heterogeneity, we recommend that a minimum of 6 units of red blood cells be available before delivery for patients with placenta accreta spectrum. These findings may inform future guidelines for predelivery blood ordering and transfusion support. SYSTEMATIC REVIEW REGISTRATION: PROSPERO, CRD42021240993.

The ongoing crisis of abortion care education and training in the United States.

PURPOSE OF REVIEW: The Dobbs vs Jackson case (Dobbs) decided by the Supreme Court of the United States (SCOTUS) in 2022 rescinded the constitutional right to abortion care, resulting in immediate state bans and severe restrictions on abortion care in almost half of the states at the time of submission. This article reviews the current state of abortion education and training as well as available curricula and programmes to support continued training. RECENT FINDINGS: Prior to Dobbs, a national residency-level training programme, the Ryan Residency Training Program, has helped expand abortion care training in residency programs nationally, yet there remained many barriers to incorporating this training into practice, including practice and hospital restrictions. New state restrictions now additionally constrain almost half of all the Ob-Gyn residency programmes. Medical students benefit from education on options counselling and values exploration. SUMMARY: Abortion care education and training is in crisis. Almost half of the Ob-Gyn residents are training in states that have banned or severely restricted abortion care. This threatens to create a workforce without critical early pregnancy management knowledge and skills. Residents are more likely to provide abortion care when they have scheduled routine training. Medical students can apply options counselling and values exploration knowledge broadly. Online education resources provide some patchwork solutions to continue abortion care education and training in this heavily restrictive landscape.

Moderating Role of Cognitive Reserve Markers Between Childhood Cognition and Cognitive Aging: Evidence From the 1946 British Birth Cohort.

BACKGROUND AND OBJECTIVES: As the population ages, differences in cognitive abilities become more evident. We investigated key genetic and life course influences on cognitive state at age 69 years, building on previous work using the longitudinal Medical Research Council National Survey of Health and Development (the British 1946 birth cohort). METHODS: Multivariable regressions investigated the association between 4 factors: (1) childhood cognition at age 8 years; (2) a Cognitive Reserve Index (CRI) composed of 3 markers: (i) educational attainment by age 26 years, (ii) engagement in leisure activities at age 43 years, and (iii) occupation up to age 53 years; (3) reading ability assessed by the National Adult Reading Test (NART) at age 53 years; and (4) APOE genotype in relation to cognitive state measured at age 69 years with Addenbrooke's Cognitive Examination, third edition (ACE-III). We then investigated the modifying role of the CRI, NART, and APOE in the association between childhood cognition and the ACE-III. RESULTS: The analytical sample comprised 1,184 participants. Higher scores in childhood cognition, CRI, and NART were associated with higher scores in the ACE-III. We found that the CRI and NART modified the association between childhood cognition and the ACE-III: for 30 additional points in the CRI or 20 additional points in the NART, the simple slope of childhood cognition decreased by approximately 0.10 points (CRI = 70: marginal effects (MEs) 0.22, 95% CI 0.12-0.32, p < 0.001 vs CRI = 100: MEs 0.12, 95% CI 0.06-0.17, p < 0.001; NART = 15: MEs 0.22, 95% CI 0.09-0.35, p = 0.001, vs NART = 35: MEs 0.11, 95% CI 0.05-0.17, p < 0.001). The association between childhood cognition and the ACE-III was nonsignificant at high levels of the CRI or NART. Furthermore, the e4 allele of the APOE gene was associated with lower scores in the ACE-III (ß = -0.71, 95% CI -1.36 to -0.06, p = 0.03) but did not modify the association between childhood cognition and cognitive state in later life. DISCUSSION: The CRI and NART are independent measures of cognitive reserve because both modify the association between childhood cognition and cognitive state.

Mixed methods evaluation of simulation-based training for postpartum hemorrhage management in Guatemala.

BACKGROUND: To assess if simulation-based training (SBT) of B-Lynch suture and uterine balloon tamponade (UBT) for the management of postpartum hemorrhage (PPH) impacted provider attitudes, practice patterns, and patient management in Guatemala, using a mixed-methods approach. METHODS: We conducted an in-country SBT course on the management of PPH in a governmental teaching hospital in Guatemala City, Guatemala. Participants were OB/GYN providers (n = 39) who had or had not received SBT before. Surveys and qualitative interviews evaluated provider knowledge and experiences with B-Lynch and UBT to treat PPH. RESULTS: Multiple-choice surveys indicated that providers who received SBT were more comfortable performing and teaching B-Lynch compared to those who did not (p = 0.003 and 0.005). Qualitative interviews revealed increased provider comfort with B-Lynch compared to UBT and identified multiple barriers to uterine balloon tamponade implementation. CONCLUSIONS: Simulation-based training had a stronger impact on provider comfort with B-Lynch compared to uterine balloon tamponade. Qualitative interviews provided insight into the challenges that hinder uptake of uterine balloon tamponade, namely resource limitations and decision-making hierarchies. Capturing data through a mixed-methods approach allowed for more comprehensive program evaluation.

Is Engagement in Intellectual and Social Leisure Activities Protective Against Dementia Risk? Evidence from the English Longitudinal Study of Ageing.

BACKGROUND: Studies have suggested that mentally stimulating activities and socially engaged lifestyles may reduce dementia risk; however, it is unclear which activities are more beneficial. OBJECTIVE: We investigated intellectual and social leisure activities in relation to dementia incidence and explored the modifying role of sex and marital status in these associations. METHODS: The sample was comprised of 8,030 participants aged 50+ from the English Longitudinal Study of Ageing, who joined at wave 1 (2002-2003), or waves 3 (2006-2007), or 4 (2008-2009). The end of the study period was wave 8 (2016-2017). Subdistribution hazard models investigated the role of leisure activities grouped into intellectual and social domains in relation to dementia while accounting for the risk of death. Subsequent analyses were conducted with individual leisure activities. RESULTS: During the study period of up to 15 years, 412 participants developed dementia, and 2,192 died. We found that increased engagement in the intellectual activities' domain was associated with a decreased dementia incidence (SHR 0.85, 95% CI 0.76-0.96, p = 0.007), independent of the risk of death in married individuals, but not in those who were single, divorced, or widowed. Individual analyses for each leisure activity showed independent associations for reading newspapers in females (SHR 0.65, 95% CI 0.49-0.84, p = 0.001), mobile phone usage in males (SHR 0.61, 95% CI 0.45-0.84, p = 0.002), and having hobbies for married individuals (SHR 0.70, 95% CI 0.51-0.95, p = 0.02). CONCLUSION: We found that intellectual leisure activities contribute to lower dementia risk in a representative population of English adults, suggesting intervention opportunities.

Interventions to improve vitamin D status in at-risk ethnic groups during pregnancy and early childhood: a systematic review.

OBJECTIVE: To systematically review the literature with the primary aim of identifying behavioural interventions to improve vitamin D stores in children from at-risk ethnic groups. DESIGN: Review based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PROSPERO registration number: CRD42017080932. Health Behaviour Model and Behaviour Change Wheel framework constructs used to underpin evaluation of interventions. Methodological quality evaluated using Cochrane Risk of Bias, Cochrane ROBINS-I and NHLBI tools. SETTING: Databases Cochrane Library, MEDLINE, EMBASE, CINAHL with secondary search of Google Scholar. No country limits set. Papers between January 1990 and February 2018, published in English included. Anticipating study heterogeneity, outcome measures not pre-specified and identified from individual full papers. Updated literature search November 2020. PARTICIPANTS: Patient or population including pregnant women, newborns and children aged under 18 years, from Asian or African ethnic groups. RESULTS: Of 10 690 articles screened, 298 underwent full-text review, with 24 ultimately included for data extraction. All identified studies conducted a vitamin D pharmacological supplementation intervention, with two also incorporating a behavioural intervention strategy. No study explicitly defined a primary aim of evaluating a behavioural intervention, undertaken to study its effect on vitamin D supplement uptake. CONCLUSIONS: There is a need to address the paucity of data in ethnic at-risk children on how behavioural interventions ideally developed and co-produced with the community under study, affect and help improve vitamin D uptake, within the antenatal and pregnancy phase as well as during childhood.

Changing the landscape of obstetric resident education in low- and middle-income countries using simulation-based training.

OBJECTIVE: To evaluate simulation-based training (SBT) in low- and-middle-income countries (LMIC) and the long-term retention of knowledge and self-efficacy. METHODS: We conducted an SBT course on the management of postpartum hemorrhage (PPH), shoulder dystocia (SD), and maternal cardiac arrest (MCA) in three government teaching hospitals in Guatemala. We evaluated changes in knowledge and self-efficacy using a multiple-choice questionnaire for 46 obstetrics/gynecology residents. A paired Student's t test was used to analyze changes at 1 week and 6 months after the SBT. RESULTS: There was an increase in scores in clinical knowledge of MCA (p < 0. 001, 95% confidence interval [CI] 0.81-1.49) and SD (p < 0.001, 95% CI 0.41-1.02) 1 week after SBT, and a statistically insignificant increase in PPH scores (p = 0.617, 95% CI -0.96 to 0.60). This increase in scores was maintained after 6 months for MCA (p < 0.001, 95% CI 0.69-1.53), SD (p = 0.02 95% CI 0.07-0.85), and PPH (p = 0.04, 95% CI 0.01-1.26). For MCA and SD, the levels of self-efficacy were increased 1 week following training (p < 0.001, 95% CI 0.83-2.30 and p = 0.008, 95% CI 0.60-3.92, respectively), and at 6 months (p < 0.001, 95% CI 0.79-2.42 and p = 0.006, 95% CI 0.66-3.81, respectively). There was a slight increase in PPH self-efficacy scores 1 week after SBT (p = 0.73, 95% CI -6.05 to 4.41), maintained after 6 months (p = 0.38, 95% CI -6.85 to 2.85). CONCLUSION: SBT was found to be an effective and feasible method to increase short- and long-term clinical knowledge and self-efficacy of obstetric emergencies in LMIC.

Markers of cognitive reserve and dementia incidence in the English Longitudinal Study of Ageing.

BACKGROUND: In the current climate of an ageing population, it is imperative to identify preventive measures for dementia. AIMS: We implemented a multifaceted index of cognitive reserve markers and investigated dementia incidence over 15 years of follow-up in a representative sample of the English population. METHOD: Data were 12 280 participants aged ≥50 years from the English Longitudinal Study of Ageing, free from dementia at their baseline assessments during wave 1 (2002-2003), 3 (2006-2007) or 4 (2008-2009), and followed up until wave 8 (2016-2017). The Cognitive Reserve Index was constructed as a composite measure of education, occupation and leisure activities, using a standardised questionnaire. Cox proportional hazards regression models were used to estimate the hazard ratios of dementia in relation to cognitive reserve levels (low, medium and high) and its components (education, occupation and leisure activities). RESULTS: During the follow-up period, 602 participants aged 56-99 years developed dementia. Higher levels of cognitive reserve (hazard ratio 0.65, 95% CI 0.48-0.89, P = 0.008) were associated with a lower risk of dementia. An individual analysis of its components showed that higher levels of education (hazard ratio 0.56, 95% CI 0.36-0.88, P = 0.012), occupation (hazard ratio 0.72, 95% CI 0.56-0.91, P = 0.008) and leisure activities (hazard ratio 0.74, 95% CI 0.56-0.99, P = 0.047) were predictive of a reduced dementia risk, with the first two components particularly protective in younger participants (<85 years). CONCLUSIONS: This study showed a reduced risk of dementia for individuals with a higher level of cognitive reserve, represented by higher education, complex occupations and multifaceted level of leisure activities.

Response suppression, strategy application, and working memory in the prediction of academic performance and classroom misbehavior: A neuropsychological approach.

BACKGROUND: Neurological illness can produce a disorganization of behavior, including verbal disinhibition, despite apparent preserved intelligence. Neuropsychological tests of such behavioral control mechanisms may predict real-world performance of healthy people, such as success or misbehavior in educational contexts. METHOD: In two separate studies, we examined how the Hayling Test of verbal response suppression predicts grades and classroom misbehavior. RESULTS: Verbal suppression errors and spontaneous strategy use were significant predictors of undergraduate grades. Using a modified version of the Hayling Test designed to reduce strategic responding with high school students (mean age 16), higher grades were predicted by shorter response suppression latencies and better working memory scores, and classroom misbehavior was predicted by lower working memory scores. CONCLUSION: Verbal response suppression and spontaneous strategy use, both closely linked to disorganized behavior in neuropsychological patients, predict academic achievement but seem unrelated to classroom misbehavior, which is associated with weakness in working memory.

Waiting it out: consultation delays prolong in-patient length of stay.

BACKGROUND: Decreasing delays for hospitalised patients results in improved hospital efficiency, increased quality of care and decreased healthcare expenditures. Delays in subspecialty consultations and procedures can cause increased length of stay due to reasons outside of necessary medical care. OBJECTIVE: To quantify, describe and record reasons for delays in consultations and procedures for patients on the general medicine wards. METHODOLOGY: We conducted weekly audits of all admitted patients on five Internal Medicine teams over 8 weeks. A survey was reviewed with attending physicians and residents on five internal medicine teams to identify patients with a delay due to consultation or procedure, quantify length of delay and record reason for delay. RESULTS: During the study period, 316 patients were reviewed and 48 were identified as experiencing a total of 53 delays due to consultations or procedures. The average delay was 1.8 days for a combined total of 83 days. Top reasons for delays included scheduling, late response to page and a busy service. The frequency in length of consult delays vary among different specialties. The highest frequency of delays was clustered in procedure-heavy specialties. CONCLUSION: This report highlights the importance of reviewing system barriers that lead to delayed service in hospitals. Addressing these delays could lead to reductions in length of stay for inpatients.

Estimación de la Función Cognitiva Premórbida con el Test de Acentuación de Palabras / Estimation of Premorbid Cognitive Function with the Word Accentuation Test

Resumen Objetivo: La valoración premórbida de la función cognitiva es esencial para la interpretación de la presencia y severidad del deterioro cognitivo. El método más confiable para evaluar esto en países hispanohablantes es el Word Accentuation Test (WAT) / Test de Acentuación de Palabras (TAP), ya que predice los resultados de pruebas de inteligencia mediante una regresión linear. Resultados: En una muestra ecuatoriana, el TAP tiene buena consistencia interna y confiabilidad test-retest. La correlación del TAP con los puntajes del WAIS-IV es alta (r=.827), permitiendo el desarrollo de una ecuación de regresión para estimar las puntuaciones de CI. Además, se encontró que una muestra de pacientes con demencia funcionaba normalmente en el TAP en comparación con el grupo de control. Esto sugiere que el rendimiento del TAP se mantiene en la presencia de una enfermedad neurológica con un deterioro cognitivo y puede usarse para valorar inteligencia premórbida. Conclusiones: El TAP tiene buenas propiedades psicométricas y puede ser utilizado para estimar puntuaciones de pruebas de inteligencia en participantes sanos. También puede valorar puntajes de inteligencia premórbida en pacientes con enfermedades neurológicas o psiquiátricas, permitiendo una interpretación clara de la gravedad del deterioro. Esta evaluación podría utilizarse en contextos clínicos y de investigación.

Abstract Objectives: Premorbid estimation of cognitive function is essential for the interpretation of the presence and severity of actual cognitive impairment. The most reliable method in Spanish speaking countries is with the Word Accentuation Test (WAT) / Test de Acentuación de Palabras (TAP). This is used to predict intelligence test scores by linear regression. Results: In an Ecuadorian sample the TAP was found to have good internal consistency and test-retest reliability. The correlation of the TAP with WAIS-IV full IQ scores was high (r= .827), allowing the development of a regression equation to estimate IQ scores from TAP performance. Furthermore, a sample of dementia patients was found to perform normally on the WAT compared to a matched control group. This suggests that WAT performance holds in the presence of neurological illness with associated cognitive impairment. Conclusions: The WAT has good psychometric properties and can be used to rapidly estimate actual intelligence test scores in healthy participants. It can also estimate premorbid intelligence scores in patients with neurological or psychiatric illnesses, allowing a clearer interpretation of the severity of impairment. This simple assessment could be used in various research and clinical contexts.
