No full textComparison of early literacy attitudes of Head Start teachers and the frequency of literacy activities in Wisconsin Head Start classrooms
No full textPlan BHead Start began a school readiness focus in 2000 with an emphasis on accountability when the National Head Start Bureau issued an outcomes framework for all Head Start programs. This was followed up by President Bush’s early childhood initiative, Good Start, Grow Smart. This initiative focused on early literacy and national accountability for all Head Start programs. In response to the national early literacy emphasis, the researcher developed a teacher survey to focus on early literacy attitudes, importance of early literacy activities and frequency of early literacy activities in Head Start classrooms. Demographic information was utilized to compare years of experience and educational level of teachers to attitudes and importance of early literacy in Head Start. Data was collected by sending a survey to 200 Head Start teachers in 56 Head Start agencies throughout the state of Wisconsin in February, 2002. One hundred forty six surveys were returned to the researcher, which yields a return rate of 73%. The Head Start teachers in Wisconsin were asked to participate in the study through their Head Start Director. The Head Start Directors asked teachers in their programs to complete the surveys. If the teachers wished to participate in the study, they completed the survey and returned it in a self-addressed stamped envelope. Level of teacher education and years of teaching experience made a difference in early literacy in Head Start classrooms. As educational level increases, attitudes about early literacy tend to also increase. A statistical significant difference was found at the .05 level between teachers with Associate degrees from those with Bachelor and Master level degrees. Along with early literacy attitudes increasing with educational attainment, the researcher also concluded that teachers feel more skilled teaching early literacy activities as their educational level increases. A significant difference at the .01 level was found between teachers with CDA’s, Associate and Bachelor degrees from those with Master’s degrees. As with level of education, a significant difference was found when comparing early literacy attitudes with years of teaching experience. Teachers with 3-5 years experience scored significantly different at the .05 level from those with 6-10 years of experience. Teachers with 6-10 years of experience scored highest in section two of the survey, attitudes about literacy. Teachers with 2 years or less of teaching experience scored the highest in section three of the survey, importance of teaching early literacy skills and teachers with 11 years or more of teaching experience scored highest on section four of the survey, frequency of literacy activities. This study would be beneficial if repeated one year from now, once the Head Start teachers have been trained in the CIRLCE literacy model and have had a chance to implement literacy strategies in the classroom. Comparing current early literacy attitudes, early literacy importance and frequency early literacy activities may be very different one year from now in Head Start classrooms based on continued training and mentoring support within their programs. The information collected though this survey was very useful in delineating necessary literacy training and technical assistance areas for Head Start teachers. Teachers reported spending the least amount of time on helping students to find letters in words and act out events from stories. These activities are two important literacy aspects for young children to experience. The data also showed teachers with 2 years or less teaching experience reported the highest scores in importance of early literacy skills. It is important for training and technical assistance providers to appreciate teacher differences based on years of teaching experience and level of education

Advanced head and neck surgery training during the COVID-19 pandemic.
No full textBackgroundThe COVID‐19 pandemic has significantly impacted medical training. Here we assess its effect on head and neck surgical education.MethodsSurveys were sent to current accredited program directors and trainees to assess the impact of COVID‐19 on the fellow’s experience and employment search. Current fellows’ operative logs were compared with those of the 2018 to 2019 graduates.ResultsDespite reduction in operative volume, 82% of current American Head and Neck Society fellows have reached the number of major surgical operations to support certification. When surveyed, 86% of program directors deemed their fellow ready to enter practice. The majority of fellows felt prepared to practice ablative (96%), and microvascular surgery (73%), and 57% have secured employment to follow graduation. Five (10%) had a pending job position put on hold due to the pandemic.ConclusionsDespite the impact of the COVID‐19 pandemic, current accredited trainees remain well‐positioned to obtain proficiency and enter the work‐force.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/156209/2/hed26252.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/156209/1/hed26252_am.pd
Proton Therapy for Head and Neck Adenoid Cystic Carcinoma: Initial Clinical Outcomes
No full textBackground
The purpose of this study was to report outcomes of proton therapy in head and neck adenoid cystic carcinoma.
Methods
We conducted a retrospective analysis of 26 patients treated between 2004 and 2012. Twenty patients (77%) had base of skull involvement; 19 (73%) were treated for initial disease and 7 (27%) for recurrent disease. Twenty patients were treated postoperatively, 6 after biopsy alone and 24 had positive margins or gross residual disease. Median dose delivered was 72 Gy (relative biological effectiveness [RBE]).
Results
Median follow-up was 25 months (range, 7–50 months). The 2-year overall survival was 93% for initial disease course and 57% for recurrent disease (p = .19). The 2-year local control was 95% for initial disease and 86% for recurrent disease (p = .48). The 2-year distant metastatic rate was 25%. Late toxicity of grade 0 or 1 was seen in 17 patients, grade 2 in 5, grade 3 in 2, grade 4 in 1, and grade 5 in 1.
Conclusion
Initial outcomes of proton therapy are encouraging. Longer follow-up is required
Corrected head position.
No full textBackground: Historically, many reference lines and planes of the human skull have been used in an attempt to depict the head in a natural head position (NHP) which is a relaxed/balanced position when looking ahead at their eye level. Head position correction has been attempted in fields such as anatomy, art, anthropology, orthodontics, oral and maxillofacial surgery, plastic surgery, and forensics. In orthodontics, oral and maxillofacial surgery, and plastic surgery, corrected head position (CHP) is particularly important for diagnosis of the normality/protrusion/retrusion of the patient’s facial skeleton. Usually a single plane, such as Frankfurt horizontal, is used to correct head position, but its angulation is variable between individuals, because each individual’s anatomy is unique. It has been found previously that the Neutral Horizontal Axis (NHA), Frankfurt horizontal (FH), Krogman-Walker plane (KW plane), and Palatal plane (P plane) demonstrated near parallelism, and these planes averaged -1 to -2 degrees from the true horizontal (HOR, which is a horizontal plane determined as being perpendicular to the earth’s gravitational force) with subjects in NHP. Methods: Craniofacial planes were measured in an Aboriginal Australian sample and in two contemporary samples obtained from Australian orthodontic practices, and the findings were compared with previous studies. Each sample consisted of 40 individuals (20 males and 20 females) with subjects in NHP. The Aboriginal Australian sample was longitudinal (T1, mean age 10 years; T2, mean age 14 years, and T3, mean age 18 years) enabling NHP to be assessed over approximately 8 years. A soft tissue Ear - nose plane (EN plane) was also investigated. Results: NHP reproducibility over 8 years demonstrated a mean of absolute difference of 2.9 degrees, with a range of differences from -7.9 to 8.2 degrees and a standard deviation of differences equal to 3.6 degrees. The Neutral Horizontal Axis (NHA), Frankfurt horizontal (FH), Krogman-Walker plane (KW plane), and Palatal plane (P plane) demonstrated near parallelism with each other, and averaged between 0 and -3 degrees from HOR. On average, EN plane was horizontal but was variable. Conclusions: NHP is not consistently reproducible at the individual level. For hard tissue images, the combined use of NHA, FH, KW plane, and P plane enables prediction of CHP. Additionally, the rectangular shape of the lower orbit - nasal airway region appears to be useful for correcting head position. In facial soft tissue images, EN plane in combination with other visual factors helps to correct head position. Simple geometry enables this head position correction to be performed from any view of the head where relevant landmarks are seen.Thesis (D.Clin.Dent.) -- University of Adelaide, School of Dentistry, 200
Review of head-to-head study designs in rheumatoid arthritis
No full textAbstractObjectiveTreatment options available to patients with rheumatoid arthritis (RA) are ever-changing, and understanding the similarities and differences of efficacy and safety between different RA therapies is of key importance in order to facilitate treatment decisions by both the patient and physician. Very few head-to-head, peer-reviewed trials exist; instead, evidence for efficacy of treatments is often ascertained from placebo-controlled trials, registries and meta-analyses, which often do not sufficiently address the relative effectiveness of two medications.MethodsA targeted review of indirect comparison methods, and ongoing and published clinical studies assessing the efficacy and safety, and the comparative efficacy and safety of biologic disease modifying antirheumatic drugs in RA.ResultsCritical elements that should be considered when designing head-to head trials are described using examples of true head-to-head and placebo-controlled randomized controlled trials (RCTs). The appropriate use of head-to-head trial designs is demonstrated by reviewing different examples of well-designed clinical trials, and an overview is presented of the challenges associated with indirect comparisons. This review also examines the use of studies comparing therapies to placebo, highlighting the difficulties associated with the interpretation of these studies.ConclusionsFor comparative trials to contribute to evidence-based decision making in the treatment of RA, patient populations and treatment regimens as similar as possible to those used in routine clinical practice should be employed and the trial should be appropriately designed to answer the specific question asked
Head and neck cancers in Australia
No full textThis report on head and neck cancers in Australia presents the latest available information on incidence, mortality, survival and hospitalisations.
Overview
Head and neck cancer is a term used to describe a range of cancers that occur in the throat (pharynx and larynx), nose, sinuses and mouth.
This report presents the most recent data available on head and neck cancer incidence, mortality, survival and hospitalisations and also describes risk factors that can contribute to a person developing head and neck cancer.
The report also includes a \u27spotlight\u27 section which discusses the human papillomavirus (HPV) and how it contributes to head and neck cancers.
Incidence
The number of head and neck cancers diagnosed in Australia is increasing. From 1982 to 2009, the number of head and neck cancers diagnosed rose from 2,475 to 3,896.
While the number of cases diagnosed is rising, the age-standardised incidence rate for head and neck cancers fell from 19.3 per 100,000 persons in 1982 to 16.8 per 100,000 in 2009. Increases in the overall number of cases diagnosed are occurring, despite decreases in age-standardised incidence rates, because of Australia\u27s increasing and ageing population.
The number of cases diagnosed in 2009 was higher for males than females. Males accounted for 73.8% (2,875) of head and neck cancers compared to 26.2% (1,021) for females.
Mortality
Similar to the number of cases diagnosed, the number of deaths from head and neck cancers rose from 752 in 1982 to 944 in 2011.
The age-standardised mortality rate fell from 6.1 per 100,000 persons in 1982 to 3.8 per 100,000 in 2011. Increases in the overall number of deaths due to head and neck cancers are occurring, despite a drop in the age-standardised mortality rates, because of the growth and ageing of Australia\u27s population.
Males accounted for a higher number of deaths in 2011 than females, with 73.2% (691) of deaths from head and neck cancers among males compared to 26.8% (253) for females.
Survival
Overall survival from head and neck cancers is improving. There was a rise in 5-year relative survival from 61.8% in 1982-1987 to 68.2% in 2006-2010. One-year relative survival for males and females in 2006-2010 were broadly comparable. However, 5-year relative survival for females was higher at 70.4% compared to males at 67.4%.
Hospitalisations
Hositalisations for head and neck cancers are also rising. In 2011-12, there were 8,478 hospitalisations where head and neck cancer was the principal diagnosis. This was an increase of 13.8% from 2002-03 when there were 7,448 hospitalisations.
The number of hospitalisations for surgery where head and neck cancer was the principal diagnosis also increased over time, from 3,305 in 2002-03 to 3,725 in 2011-12. This was an overall increase of 12.7%
