Evolution of Clinical Trials throughout History

The history of clinical research accounts for the high ethical, scientific, and regulatory standards represented in current practice. In this review, we aim to describe the advances that grew from failures and provide a comprehensive view of how the current gold standard of clinical practice was born. This discussion of the evolution of clinical trials considers the length of time and efforts that were made in order to designate the primary objective, which is providing better care for our patients. A gradual, historic progression of scientific methods such as comparison of interventions, randomization, blinding, and placebos in clinical trials demonstrates how these techniques are collectively responsible for a continuous advancement of clinical care. Developments over the years have been ethical as well as clinical. The Belmont Report, which many investigators lack appreciation due to time constraints, represents the pinnacle of ethical standards and was developed due to significant misconduct. Understanding the history of clinical research may help investigators appreciate the responsibility of conducting human subjects’ research

Symptomology Associated with in Utero Exposures to Polysubstance in an Appalachian Population.

Neonatal abstinence syndrome (NAS) is seen as a very high rate at our institution in Huntington, West Virginia, and the majority of exposures are polysubstance in nature. Polysubstance can have different meaning for each region. At our institution, polysubstance is any combination of opioids, gabapentin, methamphetamine, cocaine, marijuana, benzodiazepines, nicotine or other neuroactive substances with 3-4 substances being the norm. Rapidly changing combinations of drug use and the lack of literature create a difficult situation for clinicians who are often reliant on treatment recommendations that lack references or conclusive data supporting the clinical approaches. Elucidating withdrawal symptoms consistent with in utero exposures to particular drug combinations is difficult. Many substances induce similar withdrawal symptoms in neonates and the vast majority of cases present as polysubstance exposure. Standard methodology often leads to a research approach which isolates populations and substance of exposure to determine the individual effects on the neonate. In some drug combinations, like opioid and gabapentin exposure, the substances in concert create symptoms and complications that are not observed with either drug alone. The history of responses to substance use epidemics has been to handle each drug as a separate disease process, this is no longer a viable option. The following is a review of the literature available discussing individual substance withdrawal characteristics in neonates combined with the clinical insight gained at our hospital from treating such high rates of complex polysubstance exposure

Size-optimized 32-channel brain arrays for 3 T pediatric imaging

Size-optimized 32-channel receive array coils were developed for five age groups, neonates, 6 months old, 1 year old, 4 years old, and 7 years old, and evaluated for pediatric brain imaging. The array consisted of overlapping circular surface coils laid out on a close-fitting coil-former. The two-section coil former design was obtained from surface contours of aligned three-dimensional MRI scans of each age group. Signal-to-noise ratio and noise amplification for parallel imaging were evaluated and compared to two coils routinely used for pediatric brain imaging; a commercially available 32-channel adult head coil and a pediatric-sized birdcage coil. Phantom measurements using the neonate, 6-month-old, 1-year-old, 4-year-old, and 7-year-old coils showed signal-to-noise ratio increases at all locations within the brain over the comparison coils. Within the brain cortex the five dedicated pediatric arrays increased signal-to-noise ratio by up to 3.6-, 3.0-, 2.6-, 2.3-, and 1.7-fold, respectively, compared to the 32-channel adult coil, as well as improved G-factor maps for accelerated imaging. This study suggests that a size-tailored approach can provide significant sensitivity gains for accelerated and unaccelerated pediatric brain imaging

Anthropometric cranial measurements of normal newborn in Sergipe - Northeast of Brazil

O estudo antropométrico do crânio é fundamental para a avaliação do recém-nascido. As medidas antropométricas usadas na atualidade são baseadas em resultados obtidos há mais de cinco décadas, os quais não são capazes de determinar um padrão nacional em decorrência de possíveis influências de algumas etnias. Realizamos estudo descritivo analítico em uma Maternidade em Aracaju-SE, com medidas de perímetro cefálico, distancia biauricular e anteroposterior, índice cefálico e medida da fontanela; foram examinadas 450 recém-nascidos com idade gestacional entre 37 e 42 semanas; 49,3% era do gênero masculino e 50,6% do feminino. O perímetro cefálico variou entre 30,0 cm e 39,8 cm com média de 34,14±2,48 com P50 34 cm. O índice cefálico variou entre 0,69 e 1,13 com média de 0,98±0,06 com P50 1. Foi feito uma comparação entre os estudos estrangeiros e brasileiros; o recém-nascido sergipano aproxima-se mais dos resultados obtidos nos estudos da região sudeste do que dos resultados da região nordeste, geograficamente semelhante. A possibilidade de influencias étnicas foi levantada, como também a necessidade de realizar um estudo multicêntrico para criar um perfil antropométrico do recém-nascido brasileiro. _________________________________________________________________________________________ ABSTRACT: The anthropometric mesureaments of the skull is essential for the evaluation of the newborn. The anthropometrics measureaments utilized at the present time are based in the results obtained for more than five decades, which are not able to determine a national pattern mostly likely due to some ethnic influences. We carried out an analytical descriptive study in a maternity hospital in Aracaju-Sergipe, Northeast of Brazil. Measurements of cephalic perimeter, biauricular and anteroposterior distances, cephalic index and fontanels were obtained from 450 newborns with gestacional age from 37 and 42 weeks; 49.3% were male and 50.6% female. The cephalic perimeter ranged from 30.0 cm to 39.8 cm with mean value of 34.14±2.48 P50 34 cm, and cephalic index ranged from 0.69 and 1.13 with mean value of 0.98±0.06 P50 1. A comparison was made between brazilian and foreign studies; the results of the newborn from Sergipe were closer to results obtained in the southeast region than the ones obtained in the northeast region itself. The possibility of ethnical influences was raised as well as the need to design a multicentric study in order to define an anthropometric profile of the brazilian newborn

Neuropsychological Correlates of Cystic Fibrosis in Patients 5 to 8 Years Old

Intellectual, academic, and neuropsychological tests were administered to 20 children with cystic fibrosis (CF). Results were compared to test results from 20 controls matched for gender, age, and socioeconomic status. No differences between the groups were found. For children with CF, Verbal IQ, sensory-perceptual skills, and incidental learning correlated (rs = .39-.67) with Shwachman criteria of disease severity, with significant positive relations with the Growth and Nutrition measure, an index of the severity of the disease. Processing of tactile-perceptual information may be particularly vulnerable to disease severity. This study provides more information than previously available on the neuropsychological status of young children with CF, and it offers some hypotheses regarding the relation between disease severity and neuropsychological function.published_or_final_versio
