Summer Learning Loss among Elementary School Children with Reading Disabilities
This study investigated whether students with reading disabilities (RD) showed greater regression in reading skills than did non-RD students over the summer vacation. The RD group consisted of 30 students in grades 4 to 6 from a private school for students with learning disabilities and a comparison group of 30 average readers in grades 4 to 6 attending a public school. All students were tested in May/June and September on measures of reading achievement, phonological processing, and oral receptive vocabulary. Significant regression in the RD groupâs scores was found on speed of sight word reading, speeded phonological decoding, and untimed sight word reading. These results suggested that students with RD tend to decline in areas that require automatic reading skills. Implications for students with RD in relation to periods of extended absence from formal literacy instruction are discussed
Reading Deficits in Pregnant Teens: Implications for Policy and Practice
The present study examined the relationship between teen pregnancy and reading achievement. Girls ages 14 to 17 who were pregnant at the time of testing (n=3) and girls who had never been pregnant (n=19) were compared on measures of reading achievement. Specifically, the WRAT-4 was used to measure lower-order single word reading and spelling skills, and the TOWRE and the NDRT were used to measure higher-order reading fluency and comprehension. A MANOVA was conducted to investigate whether there was a difference between pregnant and never-pregnant teens in one or more domains of reading achievement. Results did not indicate statistically significant differences between groups. Follow-up ANOVAs were conducted to compare pregnant and never-pregnant teens on measures of higher-order reading skills. No differences between groups were noted in any analysis. Due to small sample size, the power of the analyses was limited. Future research should be conducted with a larger sample
Using Curriculum-Based Measurement in the Assessment of Reading Disabilities
The present investigation looked at studentsâ reading achievement within the context of the Peer Assisted Learning Strategies (PALS) intervention. It consisted of three separate studies, all of which are related to reading achievement and intervention during the early years of school. The purpose of Study One was to determine whether students who are identified with reading disabilities via psychological assessment report make improvements over the school year subsequent to the implementation of this report. It was hypothesized that when teachers have access to psychological assessment reports, they will better understand their studentsâ individual learning needs and that this will translate to improved scores in reading. This hypothesis was not supported; those students who underwent psychological assessment did not show significant improvement in their reading skills as compared to students who did not undergo psychological assessment. Study Two examined whether the reading skills of students who are considered low achievers in reading tend to regress to a greater extent during the traditional summer vacation, as compared to their high- and typically-peers, whether it takes the low achievers longer to recover from summer loss, and whether they show more shallow learning trajectories over the school year. The summer learning loss hypothesis was partially supported. In terms of summer learning loss, on a measure of word reading administered following the summer after Senior Kindergarten, the low achieversâ scores remained stable over the summer, while the average and high achieversâ scores increased. It is thought that the Grade 1 year marks an important time for the onset of summer learning loss as a phenomenon. Study Three assessed the role of language prosody as a predictor of reading outcomes within the PALS intervention. Language prosody was not found to be a significant predictor of progress in PALS. The utility of curriculum-based measurements in the assessment of reading disabilities in a Canadian context is discussed

ted a total of 103 reports on glycan distributions. The
principal objective of this study was to report and compare
results for the full range of analytical methods presently
used in the glycosylation analysis of mAbs. Therefore,
participation was unrestricted, with laboratories
choosing their own measurement techniques. Protein glycosylation
was determined in various ways, including at
the level of intact mAb, protein fragments, glycopeptides,
or released glycans, using a wide variety of methods for
derivatization, separation, identification, and quantification.
Consequently, the diversity of results was enormous,
with the number of glycan compositions identified by
each laboratory ranging from 4 to 48. In total, one hundred
sixteen glycan compositions were reported, of which 57
compositions could be assigned consensus abundance
values. These consensus medians provide communityderived
values for NISTmAb PS. Agreement with the consensus
medians did not depend on the specific method or
laboratory type. The study provides a view of the current
state-of-the-art for biologic glycosylation measurement
and suggests a clear need for harmonization of glycosylation
analysis methods. Molecular & Cellular Proteomics

Assessing the acceptability of self-sampling for HPV among Haitian immigrant women: CBPR in action
To determine whether pairing self-sampling for HPV with community health workers (CHWs) is a culturally acceptable method for cervical cancer screening among Haitian immigrant women residing in Little Haiti, the predominately Haitian neighborhood in Miami, FL.As part of a larger, ongoing community-based participatory research (CBPR) initiative in Little Haiti, Haitian CHWs recruited 246 eligible women to this study. Participants provided self-collected cervical specimens for HPV testing and answered a series of questions about their experience with self-sampling for HPV.The vast majority of women (97.6%) was comfortable using the self-sampler at home, would recommend this screening method to their friends and/or family members (98.4%), and described the sampler as easy to use (95.1%). Additionally, 97% of all self-collected specimens were deemed adequate for HPV testing.When paired with CHWs, who are of Haitian descent and well respected in Little Haiti, self-sampling is a highly acceptable method of cervical screening for Haitian women in this ethnic enclave. This approach addresses critical access barriers, including poverty, language difficulties, and sociocultural concerns about modesty, that may similarly affect Pap smear utilization among other immigrant or medically underserved population sub-groups. Coupled with generally positive reviews of the device, the low rate of insufficient specimens for testing suggests that this device is promising for use in non-clinical settings

The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise stated.International audienceBACKGROUND:Plasmodium vivax malaria is a major public health problem in French Guiana. Some cases of resistance to chloroquine, the first-line treatment used against P. vivax malaria, have been described in the Brazilian Amazon region. The aim of this study is to investigate a possible dispersion of chloroquine-resistant P. vivax isolates in French Guiana. The genotype, polymorphism and copy number variation, of the P. vivax multidrug resistance gene-1 (pvmdr1) have been previously associated with modification of the susceptibility to chloroquine.METHODS:The pvmdr1 gene polymorphism was evaluated by sequencing and copy number variation was assessed by real-time PCR, in P. vivax isolates obtained from 591 symptomatic patients from 1997 to 2013.RESULTS:The results reveal that 1.0% [95% CI 0.4-2.2] of French Guiana isolates carry the mutations Y976F and F1076L, and that the proportion of isolates with multiple copies of pvmdr1 has significantly decreased over time, from 71.3% (OR = 6.2 [95% CI 62.9-78.7], p < 0.0001) in 1997-2004 to 12.8% (OR = 0.03 [95% CI 9.4-16.9], p < 0.0001) in 2009-2013. A statistically significant relationship was found between Guf-A (harboring the single mutation T958M) and Sal-1 (wild type) alleles and pvmdr1 copy number.CONCLUSIONS:Few P. vivax isolates harboring chloroquine-resistant mutations in the pvmdr1 gene are circulating in French Guiana. However, the decrease in the prevalence of isolates carrying multiple copies of pvmdr1 might indicate that the P. vivax population in French Guiana is evolving towards a decreased susceptibility to chloroquine
