“Assessment of Student Readiness for Clinical Education in Mixed-mode Curriculum Delivery: A Case Study”

Purpose – The purpose of this case study is to describe a simulation-based assessment designed to assure student readiness for a first full-time clinical experience in an entry-level Doctor of Physical Therapy program that transitioned to mixed-mode instruction during the COVID-19 pandemic. Design/methodology/approach – A cohort of 40 second-year physical therapy students whose content delivery mode, assessment methods and curricular sequence deviated from the curricular plan participated in a new assessment using standardized patients. The assessment was developed to preferentially address the knowledge, skills, abilities and professional behaviors (KSAs) that were typically assessed with other methods before the pandemic. Findings – The assessment was useful in identifying students who required additional learning experiences to meet expected levels of competence before transition to a first full-time clinical experience. It also identified KSAs that needed to be strengthened within the entire cohort of students. Research limitations/implications – This case study provides an example of feasible implementation of an assessment of student readiness for clinical education that may guide future development of standardized assessments in health profession education (HPE) programs that have or plan to transition to mixed-mode content delivery. Originality/value – This case study highlights the need and process for developing and implementing additional assessments in HPE programs when planned changes or unexpected variations in curriculum delivery occur. This evidence-based assessment preferentially addresses the affective domain of learning and includes competency standards that have recently been developed for physical therapy education in the USA

Evaluating the effect of storage conditions on milk microbiological quality and composition

peer-reviewedIn this study, the effect of storage temperature (2 or 4°C) on the composition of milk and microbiological load was investigated over 96 h. Milk samples were collected from farm bulk milk tanks after one complete milking and stored at 2 or 4°C over 96 h. Total bacterial count (TBC), psychrotrophic bacterial count (PBC) and proteolytic bacterial count (PROT) were affected by storage time and temperature and varied significantly between farms (P < 0.05). The levels of TBC, PBC and PROT bacterial count increased from 4.37 to 6.15 log cfu/mL, 4.34 to 6.44 log cfu/mL and 3.72 to 4.81 log cfu/mL, respectively, when the milk was stored for 96 h at 2°C. The milk samples stored at 4°C had higher increases in these bacterial counts after 72 h in comparison to milk samples stored at 2°C. The casein fraction content was lower in milk samples stored at 4°C, which could be due to high levels of PROT bacteria or enzyme activity in these samples. Milk stored for 96 h at 2°C has less impact on composition or processability parameters compared to milk stored at 4°C

Occupational Interest Patterns and Personality Styles of Freshman Student-Athletes

The existence and relationship of common personality styles and occupational orientations were explored. The study considered Holand's (1973) vocational theory and Strack's (1991) eight basic personality types. Student-athletes (n=36) and non-athletes (n=17) enrolled in a freshman seminar for physical education majors (males = 63%) completed the Personality Adjective Check List (Straclk, 1991) and the Strong Interest Inventory (Hansen & Campbell, 1985). The results suggest that student-athletes and non-athletes differ on several personality and occupacional variables and that personality sryle has an important relationship to occupational orientation and interests. A specific profile for athletes based on personality and vocational type did not emerge. Implications for athletic counseling professionals were discussed

The effect of different precooling rates and cold storage on milk microbiological quality and composition

peer-reviewedThe objective of this study was to measure the effect of different milk cooling rates, before entering the bulk tank, on the microbiological load and composition of the milk, as well as on energy usage. Three milk precooling treatments were applied before milk entered 3 identical bulk milk tanks: no plate cooler (NP), single-stage plate cooler (SP), and double-stage plate cooler (DP). These precooling treatments cooled the milk to 32.0 ± 1.4°C, 17.0 ± 2.8°C, and 6.0 ± 1.1°C, respectively. Milk was added to the bulk tank twice daily for 72 h, and the tank refrigeration temperature was set at 3°C. The blend temperature within each bulk tank was reduced after each milking event as the volume of milk at 3°C increased simultaneously. The bacterial counts of the milk volumes precooled at different rates did not differ significantly at 0 h of storage or at 24-h intervals thereafter. After 72 h of storage, the total bacterial count of the NP milk was 3.90 ± 0.09 log10 cfu/mL, whereas that of the precooled milk volumes were 3.77 ± 0.09 (SP) and 3.71 ± 0.09 (DP) log10 cfu/mL. The constant storage temperature (3°C) over 72 h helped to reduce bacterial growth rates in milk; consequently, milk composition was not affected and minimal, if any, proteolysis occurred. The DP treatment had the highest energy consumption (17.6 ± 0.5 Wh/L), followed by the NP (16.8 ± 2.7 Wh/L) and SP (10.6 ± 1.3 Wh/L) treatments. This study suggests that bacterial count and composition of milk are minimally affected when milk is stored at 3°C for 72 h, regardless of whether the milk is precooled; however, milk entering the tank should have good initial microbiological quality. Considering the numerical differences between bacterial counts, however, the use of the SP or DP precooling systems is recommended to maintain low levels of bacterial counts and reduce energy consumption

Anthropomorphic Breast Phantoms with Physiological Water, Lipid, and Hemoglobin Content for Near-Infrared Spectral Tomography

Breast mimicking tissue optical phantoms with sufficient structural integrity to be deployed as stand-alone imaging targets are developed and successfully constructed with biologically relevant concentrations of water, lipid, and blood. The results show excellent material homogeneity and reproducibility with inter- and intraphantom variability of 3.5 and 3.8%, respectively, for water and lipid concentrations ranging from 15 to 85%. The phantoms were long-lasting and exhibited water and lipid fractions that were consistent to within 5% of their original content when measured 2 weeks after creation. A breast-shaped three-compartment model of adipose, fibroglandular, and malignant tissues was created with water content ranging from 30% for the adipose simulant to 80% for the tumor. Mean measured water content ranged from 30% in simulated adipose to 73% in simulated tumor with the higher water localized to the tumor-like material. This novel heterogeneous phantom design is composed of physiologically relevant concentrations of the major optical absorbers in the breast in the near-infrared wavelengths that should significantly improve imaging system characterization and optimization because the materials have stand-alone structural integrity and can be readily molded into the sizes and shapes of tissues commensurate with clinical breast imaging

Psychosocial functioning in pediatric heart transplant recipients and their families

Across pediatric organ transplant populations, patient and family psychosocial functioning is associated with important health‐related outcomes. Research has suggested that pediatric heart transplant recipients and their families are at increased risk for adverse psychosocial outcomes; however, recent investigation of psychosocial functioning in this population is lacking. This study aimed to provide a contemporary characterization of psychosocial functioning in pediatric heart transplant recipients and their families. Associations between psychosocial function, demographic variables, and transplant‐related variables were investigated. Fifty‐six parents/guardians of pediatric heart transplant recipients completed a comprehensive psychosocial screening measure during transplant follow‐up clinic visits. Descriptive statistics, correlational analyses, and independent samples t tests were performed. Forty percent of pediatric heart transplant recipients and their families endorsed clinically meaningful levels of total psychosocial risk. One‐third of patients presented with clinically significant psychological problems per parent report. Psychosocial risk was unassociated with demographic or transplant‐related factors. Despite notable improvements in the survival of pediatric heart transplant recipients over the past decade, patients and families present with sustained psychosocial risks well beyond the immediate post‐transplant period, necessitating mental health intervention to mitigate adverse impact on health‐related outcomes.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/142422/1/petr13110.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/142422/2/petr13110_am.pd

All-optical binary counter

We experimentally demonstrate an all-optical binary counter composed of four semiconductor optical amplifier based all-optical switching gates. The time-of-flight optical circuit operates with bit-differential delays between the exclusive-OR gate used for modulo-2 binary addition and the AND gate used for binary carry detection. A movie of the counter operating in real time is presented

Reduced Purkinje cell number in essential tremor : a postmortem study

Background: Clinical and functional imaging evidence suggests that cerebellar dysfunction occurs in essential tremor (ET). In recent postmortem studies, we documented increased numbers of torpedoes (Purkinje cell axonal swellings) in ET patients without Lewy bodies. Purkinje cell loss, however, has never been rigorously assessed. Objective: To quantitatively assess the number of Purkinje cells in brains of ET patients and similarly aged controls. Methods: Postmortem cerebellar tissue was available in 14 ET cases (6 with Lewy bodies and 8 without Lewy bodies) and 11 controls. Calbindin immunohistochemistry was performed on paraffin sections of the cerebellum. Images were digitally recorded and blinded measurements of the number of Purkinje cells per millimeter of cell layer (linear density) were made. Results: Purkinje cell linear density was inversely correlated with age (r=-0.53, P=.006) and number of torpedoes (r=-0.42, P=.04). Purkinje cell linear density differed by diagnosis (mean [SD], controls, 3.46 [1.27] cells/mm; ET cases with Lewy bodies, 3.33 [1.06] cells/mm; and ET cases without Lewy bodies, 2.14 [0.82] cells/mm; P=.04), with the most significant difference between ET cases without Lewy bodies and controls, where the reduction was 38.2% (P=.04). In an adjusted linear regression analysis that compared ET cases without Lewy bodies with controls, decreased linear density (outcome variable) was associated with ET (β=.56, P=.03). Conclusions: We demonstrated a reduction in Purkinje cell number in the brains of patients with ET who do not have Lewy bodies. These data further support the view that the cerebellum is anatomically, as well as functionally, abnormal in these ET cases

Assessing the perceived value of Reflexive Groups for supporting Clergy in the Church of England

This is an Accepted Manuscript of an article published by Taylor & Francis in Mental Health, Religion and Culture on 18-7-16, available online: http://dx.doi.org/10.1080/13674676.2016.1197194Little research has been conducted to assess the effectiveness of reflexive groups in supporting clergy. For this research, eight Church of England Bishops’ Advisors for Pastoral Care and Counselling were interviewed to ascertain the value of reflexive groups. These data were analysed using a thematic analysis. Two superordinate themes emerged: Contextual issues and Benefits, along with 20 subordinate themes. An online survey, consisting of questions that came from the Bishops’ Advisors data, was then sent to reflexive group participants (n=64), to see if their experiences matched those benefits identified by the Bishops’ Advisors. The data from 37 participants was statistically analysed. The data from both sets of participants reveal that reflexive groups are psychologically beneficial to clergy. The research concludes that the implementation of reflexive groups as a way of developing self-awareness and enculturating attitudes towards resilience and self-care is important to foster psychologically and spiritually healthy practice

Infant BMI or Weight-for-Length and Obesity Risk in Early Childhood

Weight-for-length (WFL) is currently used to assess adiposity under 2 years. We assessed WFL- versus BMI-based estimates of adiposity in healthy infants in determining risk for early obesity
