Demonstrating the value of “library as place” with the MISO Survey

Purpose

The purpose of this paper is twofold. It first examines cross-institutional benchmark data about “library as place” from 99 US schools in the Measuring Information Service Outcomes (MISO) Survey (www.misosurvey.org). The data demonstrate the value of “library as place” to students in particular. Second, the paper shares case studies of how two college libraries made MISO Survey “library as place” data actionable. Lafayette College (Easton, Pennsylvania) analyzed local MISO Survey data after a renovation to validate return on investment. Earlham College (Richmond, Indiana) analyzed MISO Survey data to help secure a science library renovation and to justify an architectural study for its main library.

Design/methodology/approach

The paper begins with an analysis of “library as place” using aggregate benchmarks derived from US college and university respondents between 2012 and 2015. Specifically, the paper contrasts student and faculty perceptions of “library as place” via national benchmarks about: library services importance, satisfaction, and use (three benchmarks); hybrid online/“place-based” library services importance, satisfaction, and use (three benchmarks). Pivoting from higher education to individual, local perspectives, two case studies reveal how academic libraries used MISO Survey findings to demonstrate the value of “library as place” for renovation purposes.

Findings

The findings include that undergraduates make more frequent use than faculty of place-based services such as reference, equipment loans, and physical course reserves. Undergraduates also find most of these services more important than faculty do. Faculty makes generally more frequent use than undergraduates of online services such as library databases and the catalog. They find that these services to be more important than undergraduates do. Faculty and undergraduates use newer library discovery systems with equal frequency and find them to be equally important. Undergraduates find comfortable library spaces to be very important, and faculty considers them to be only a bit less important.

Originality/value

This is the first paper using MISO Survey data to focus on the importance and satisfaction of place-based library services involving cross-institutional comparisons for students and faculty. Previously published research using MISO Survey data have compared the use of place-based library services. This is also the first paper to offer case studies about how institutions use MISO Survey data to demonstrate the value of “library as place.”

Quality of life in pediatric cancer survivors: contributions of parental distress and psychosocial family risk

Background

Pediatric survivors of childhood cancer are at increased risk of poor quality of life and social-emotional outcomes following treatment. The relationship between parent psychological distress and child adjustment in pediatric cancer survivors has been well established. However, limited research has examined the factors that may buffer this association. The current study examined the associations between psychosocial family risk factors, parental psychological distress, and health-related quality of life (hrql) in pediatric cancer survivors.

Methods

Fifty-two pediatric cancer survivors (34 males, 18 females, mean age = 11.92) and their parents were recruited from a long-term cancer survivor clinic. Children and their parents who consented to participate completed the Pediatric Quality of Life Inventory 4.0. Parents completed a demographic information form, the Psychosocial Assessment Tool (pat 2.0) and the Brief Symptom Inventory (bsi). The Intensity of Treatment Rating (itr-3) was evaluated by the research team.

Results

Multiple regression analyses revealed that parental psychological distress negatively predicted parent-reported hrql, while treatment intensity, gender, and psychosocial risk negatively predicted parent and child-reported hrql. Psychosocial risk moderated the association between parent psychological distress and parent-reported child hrql (p = 0.03), whereby parents with high psychological distress but low levels of psychosocial risk reported their children to have higher hrql.

Conclusion

Low levels of family psychosocial risk buffer the impact of parent psychological distress on child hrql in pediatric cancer survivors. The findings highlight the importance of identifying parents and families with at-risk psychological distress and psychosocial risk in order to provide targeted support interventions to mitigate the impact on hrql.

Validation of virtual-reality-based simulations for endoscopic sinus surgery

BACKGROUND

Virtual reality (VR) simulators provide an alternative to real patients for practicing surgical skills but require validation to ensure accuracy. Here, we validate the use of a virtual reality sinus surgery simulator with haptic feedback for training in Otorhinolaryngology - Head & Neck Surgery (OHNS).

METHODS

Participants were recruited from final-year medical students, interns, resident medical officers (RMOs), OHNS registrars and consultants. All participants completed an online questionnaire after performing four separate simulation tasks. These were then used to assess face, content and construct validity. anova with post hoc correlation was used for statistical analysis.

RESULTS

The following groups were compared: (i) medical students/interns, (ii) RMOs, (iii) registrars and (iv) consultants. Face validity results had a statistically significant (P < 0.05) difference between the consultant group and others, while there was no significant difference between medical student/intern and RMOs. Variability within groups was not significant. Content validity results based on consultant scoring and comments indicated that the simulations need further development in several areas to be effective for registrar-level teaching. However, students, interns and RMOs indicated that the simulations provide a useful tool for learning OHNS-related anatomy and as an introduction to ENT-specific procedures.

CONCLUSIONS

The VR simulations have been validated for teaching sinus anatomy and nasendoscopy to medical students, interns and RMOs. However, they require further development before they can be regarded as a valid tool for more advanced surgical training.

The effects of a low-carbohydrate diet on appetite: A randomized controlled trial

BACKGROUND AND AIMS

The relationship between dietary macronutrient composition and appetite is controversial. We examined the effects of a year-long low-carbohydrate diet compared to a low-fat diet on appetite-related hormones and self-reported change in appetite.

METHODS AND RESULTS

A total of 148 adults with a body mass index 30-45 kg/m(2), who were free of diabetes, cardiovascular disease and chronic kidney disease at baseline were randomly assigned to either a low-carbohydrate diet (carbohydrate [excluding dietary fiber]<40 g/day; N = 75) or a low-fat diet (<30% energy from fat, <7% from saturated fat; N = 73). Participants in both groups attended individual and group dietary counseling sessions where they were provided the same behavioral curriculum and advised to maintain baseline levels of physical activity. Appetite and appetite-related hormones were measured at 0, 3, 6 and 12 months of intervention. At 12 months, mean changes (95% CI) in peptide YY were -34.8 pg/mL (-41.0 to -28.6) and in the low-carbohydrate group and -44.2 pg/mL (-50.4 to -38.0) in the low-fat group (net change: 9.54 pg/mL [0.6 to 18.2]; p = 0.036). Approximately 99% of dietary effects on peptide YY are explained by differences in dietary macronutrient content. There was no difference in change in ghrelin or self-reported change in appetite between the groups.

CONCLUSIONS

A low-fat diet reduced peptide YY more than a low-carbohydrate diet. These findings suggest that satiety may be better preserved on a low-carbohydrate diet, as compared to a low fat diet.

Predictors of complications in gynaecological oncological surgery: a prospective multicentre study (UKGOSOC-UK gynaecological oncology surgical outcomes and complications)

BACKGROUND

There are limited data on surgical outcomes in gynaecological oncology. We report on predictors of complications in a multicentre prospective study.

METHODS

Data on surgical procedures and resulting complications were contemporaneously recorded on consented patients in 10 participating UK gynaecological cancer centres. Patients were sent follow-up letters to capture any further complications. Post-operative (Post-op) complications were graded (I-V) in increasing severity using the Clavien-Dindo system. Grade I complications were excluded from the analysis. Univariable and multivariable regression was used to identify predictors of complications using all surgery for intra-operative (Intra-op) and only those with both hospital and patient-reported data for Post-op complications.

RESULTS

Prospective data were available on 2948 major operations undertaken between April 2010 and February 2012. Median age was 62 years, with 35% obese and 20.4% ASA grade ⩾3. Consultant gynaecological oncologists performed 74.3% of operations. Intra-op complications were reported in 139 of 2948 and Grade II-V Post-op complications in 379 of 1462 surgeries. The predictors of risk were different for Intra-op and Post-op complications. For Intra-op complications, previous abdominal surgery, metabolic/endocrine disorders (excluding diabetes), surgical complexity and final diagnosis were significant in univariable and multivariable regression (P<0.05), with diabetes only in multivariable regression (P=0.006). For Post-op complications, age, comorbidity status, diabetes, surgical approach, duration of surgery, and final diagnosis were significant in both univariable and multivariable regression (P<0.05).

CONCLUSIONS

This multicentre prospective audit benchmarks the considerable morbidity associated with gynaecological oncology surgery. There are significant patient and surgical factors that influence this risk.

Evaluation of a culture-based pathogen identification kit for bacterial causes of bovine mastitis

Accurate identification of mastitis-causing bacteria supports effective management and can be used to implement selective use of antimicrobials for treatment. The objectives of this study were to compare the results from a culture-based mastitis pathogen detection test kit ('VetoRapid', Vétoquinol) with standard laboratory culture and to evaluate the potential suitability of the test kit to inform a selective treatment programme. Overall 231 quarter milk samples from five UK dairy farms were collected. The sensitivity and specificity of the test kit for the identification of Escherichia coli, Staphylococcus aureus, coagulase-negative staphylococci, Streptococcus uberis and Enterococcus spp. ranged from 17 per cent to 84 per cent and 92 per cent to 98 per cent, respectively. In total, 23 of 68 clinical samples were assigned as meeting the requirement for antimicrobial treatment (Gram-positive organism cultured) according to standard culture results, with the test kit results having sensitivity and specificity of 91 per cent and 78 per cent, respectively. Several occurrences of misidentification are reported, including S. aureus being misidentified as coagulase-negative staphylococci and vice versa. The test kit provides rapid preliminary identification of five common causes of bovine mastitis under UK field conditions and is likely to be suitable for informing selective treatment of clinical mastitis caused by Gram-positive organisms.

Primary non-adherence to bisphosphonates in an integrated healthcare setting

We estimated primary non-adherence to oral bisphosphonate medication and examined the factors associated with primary non-adherence. Nearly 30% of women did not pick up their new bisphosphonate within 60 days. Identifying barriers and developing interventions that address patients' needs and concerns at the time a new medication is prescribed are warranted.

INTRODUCTION

To estimate primary non-adherence to oral bisphosphonate medications using electronic medical record data in a large, integrated healthcare delivery system and to describe patient and prescribing provider factors associated with primary non-adherence.

METHODS

Women aged 55 years and older enrolled in Kaiser Permanente Southern California (KPSC) with a new prescription for oral bisphosphonates between December 1, 2009 and March 31, 2011 were identified. Primary non-adherence was defined as failure to pick up the new prescription within 60 days of the order date. Multivariable logistic regression models were used to investigate patient factors (demographics, healthcare utilization, and health conditions) and prescribing provider characteristics (demographics, years in practice, and specialty) associated with primary non-adherence.

RESULTS

We identified 8,454 eligible women with a new bisphosphonate order. Among these women, 2,497 (29.5%) did not pick up their bisphosphonate prescription within 60 days of the order date. In multivariable analyses, older age and emergency department utilization were associated with increased odds of primary non-adherence while prescription medication use and hospitalizations were associated with lower odds of primary non-adherence. Prescribing providers practicing 10 or more years had lower odds of primary non-adherent patients compared with providers practicing less than 10 years. Internal medicine and rheumatology providers had lower odds of primary non-adherent patients than primary care providers.

CONCLUSION

This study found that nearly one in three women failed to pick up their new bisphosphonate prescription within 60 days. Identifying barriers and developing interventions aimed at reducing the number of primary non-adherent patients to bisphosphonate prescriptions are warranted.

The antimicrobial activity of honey against common equine wound bacterial isolates

Delayed healing associated with distal limb wounds is a particular problem in equine clinical practice. Recent studies in human beings and other species have demonstrated the beneficial wound healing properties of honey, and medical grade honey dressings are available commercially in equine practice. Equine clinicians are reported to source other non-medical grade honeys for the same purpose. This study aimed to assess the antimicrobial activity of a number of honey types against common equine wound bacterial pathogens. Twenty-nine honey products were sourced, including gamma-irradiated and non-irradiated commercial medical grade honeys, supermarket honeys, and honeys from local beekeepers. To exclude contaminated honeys from the project, all honeys were cultured aerobically for evidence of bacterial contamination. Aerobic bacteria or fungi were recovered from 18 products. The antimicrobial activity of the remaining 11 products was assessed against 10 wound bacteria, recovered from the wounds of horses, including methicillin resistant Staphylococcus aureus and Pseudomonas aeruginosa. Eight products were effective against all 10 bacterial isolates at concentrations varying from <2% to 16% (v/v). Overall, the Scottish Heather Honey was the best performing product, and inhibited the growth of all 10 bacterial isolates at concentrations ranging from <2% to 6% (v/v). Although Manuka has been the most studied honey to date, other sources may have valuable antimicrobial properties. Since some honeys were found to be contaminated with aerobic bacteria or fungi, non-sterile honeys may not be suitable for wound treatment. Further assessment of gamma-irradiated honeys from the best performing honeys would be useful.

Patient-reporting improves estimates of postoperative complication rates: a prospective cohort study in gynaecological oncology

Background:

Most studies use hospital data to calculate postoperative complication rates (PCRs). We report on improving PCR estimates through use of patient-reporting.

Methods:

A prospective cohort study of major surgery performed at 10 UK gynaecological cancer centres was undertaken. Hospitals entered the data contemporaneously into an online database. Patients were sent follow-up letters to capture postoperative complications. Grade II–V (Clavien–Dindo classification) patient-reported postoperative complications were verified from hospital records. Postoperative complication rate was defined as the proportion of surgeries with a Grade II–V postoperative complication.

Results:

Patient replies were received for 1462 (68%) of 2152 surgeries undertaken between April 2010 and February 2012. Overall, 452 Grade II–V (402 II, 50 III–V) complications were reported in 379 of the 1462 surgeries. This included 172 surgeries with 200 hospital-reported complications and 231 with 280 patient-reported complications. All (100% concordance) 36 Grade III–V and 158 of 280 (56.4% concordance) Grade II patient-reported complications were verified on hospital case-note review. The PCR using hospital-reported data was 11.8% (172 out of 1462; 95% CI 11–14), patient-reported was 15.8% (231 out of 1462; 95% CI 14–17.8), hospital and verified patient-reported was 19.4% (283 out of 1462; 95% CI 17.4–21.4) and all data were 25.9% (379 out of 1462; 95% CI 24–28). After excluding Grade II complications, the hospital and patient verified Grade III–V PCR was 3.3% (48 out of 1462; 95% CI 2.5–4.3).

Conclusion:

This is the first prospective study of postoperative complications we are aware of in gynaecological oncology to include the patient-reported data. Patient-reporting is invaluable for obtaining complete information on postoperative complications. Primary care case-note review is likely to improve verification rates of patient-reported Grade II complications.

Glucose control predicts 2-year change in lipid profile in youth with type 1 diabetes

OBJECTIVE

To test the hypothesis that a change in glycated hemoglobin (A1c) over a follow-up interval of approximately 2 years would be associated with concomitant changes in fasting lipids in individuals with type 1 diabetes (T1D).

STUDY DESIGN

All subjects with T1D diagnosed in 2002-2005 in the SEARCH for Diabetes in Youth study with at least 2 study visits ∼12 and ∼24 months after an initial visit were included (age at initial visit, 10.6 ± 4.1 years; 48% female; diabetes duration, 10 ± 7 months; 76% non-Hispanic white; A1c = 7.7% ± 1.4%). Longitudinal mixed models were fit to examine the relationship between change in A1c and change in lipid levels (total cholesterol [TC], high-density lipoprotein-cholesterol [HDL-c], low-density lipoprotein-cholesterol [LDL-c], log triglycerides [TG], and non-HDL-c) with adjustment for possible confounders.

RESULTS

Change in A1c over time was significantly associated with changes in TC, HDL-c, LDL-c, TG, and non-HDL-c over the range of A1c values. For example, for a person with an A1c of 10% and then a 2% decrease in A1c 2 years later (to 8%), the model predicted concomitant changes in TC (-0.29 mmol/L, -11.4 mg/dL), HDL-c (0.03 mmol/L, 1.3 mg/dL), LDL-c (-0.23 mmol/L, -9.0 mg/dL), and non-HDL-c (-0.32 mmol/L, -12.4 mg/dL) and an 8.5% decrease in TG (mmol/L).

CONCLUSIONS

Improved glucose control over a 2-year follow-up was associated with a more favorable lipid profile but may be insufficient to normalize lipids in dyslipidemic T1D youth needing to decrease lipids to goal.

Acyl-CoA subunit selectivity in the pikromycin polyketide synthase PikAIV: steady-state kinetics and active-site occupancy analysis by FTICR-MS

Polyketide natural products generated by type I modular polyketide synthases (PKSs) are vital components in our drug repertoire. To reprogram these biosynthetic assembly lines, we must first understand the steps that occur within the modular "black boxes." Herein, key steps of acyl-CoA extender unit selection are explored by in vitro biochemical analysis of the PikAIV PKS model system. Two complementary approaches are employed: a fluorescent-probe assay for steady-state kinetic analysis, and Fourier Transform Ion Cyclotron Resonance-mass spectrometry (FTICR-MS) to monitor active-site occupancy. Findings from five enzyme variants and four model substrates have enabled a model to be proposed involving catalysis based upon acyl-CoA substrate loading followed by differential rates of hydrolysis. These efforts suggest a strategy for future pathway engineering efforts using unnatural extender units with slow rates of hydrolytic off-loading from the acyltransferase domain.
