Support Through Remote Observation and Nutrition Guidance (STRONG), a digital health intervention to reduce malnutrition among pancreatic cancer patients: A study protocol for a pilot randomized controlled trial

Background

Malnutrition is a common and distressing condition among pancreatic cancer patients. Fewer than a quarter of pancreatic cancer patients receive medical nutrition therapy (MNT), important for improving nutritional status, weight maintenance, quality of life and survival. System, provider, and patient level barriers limit access to MNT. We propose to examine the feasibility of a 12-week multi-level, digital health intervention designed to expand MNT access among pancreatic cancer patients.

Methods

Individuals with advanced pancreatic cancer starting chemotherapy (N = 80) will be 1:1 randomized to the intervention or usual care. The Support Through Remote Observation and Nutrition Guidance (STRONG) intervention includes system-level (e.g., routine malnutrition and screening), provider-level (e.g., dietitian training and web-based dashboard), and patient-level strategies (e.g., individualized nutrition plan, self-monitoring of dietary intake via Fitbit, ongoing goal monitoring and feedback). Individuals receiving usual care will be referred to dietitians based on their oncologists' discretion. Study assessments will be completed at baseline, 4-, 8-, 12-, and 16-weeks.

Results

Primary outcomes will be feasibility (e.g., recruitment, retention, assessment completion) and acceptability. We will collect additional implementation outcomes, such as intervention adherence, perceived usability, and feedback on intervention quality via an exit interview. We will collect preliminary data on outcomes that may be associated with the intervention including malnutrition, quality of life, treatment outcomes, and survival.

Conclusion

This study will advance our knowledge on the feasibility of a digital health intervention to reduce malnutrition among individuals with advanced pancreatic cancer. Trial registration: NCT05675059, registered on December 9, 2022.

Abundant pleiotropy across neuroimaging modalities identified through a multivariate genome-wide association study

Genetic pleiotropy is abundant across spatially distributed brain characteristics derived from one neuroimaging modality (e.g. structural, functional or diffusion magnetic resonance imaging [MRI]). A better understanding of pleiotropy across modalities could inform us on the integration of brain function, micro- and macrostructure. Here we show extensive genetic overlap across neuroimaging modalities at a locus and gene level in the UK Biobank (N = 34,029) and ABCD Study (N = 8607). When jointly analysing phenotypes derived from structural, functional and diffusion MRI in a genome-wide association study (GWAS) with the Multivariate Omnibus Statistical Test (MOSTest), we boost the discovery of loci and genes beyond previously identified effects for each modality individually. Cross-modality genes are involved in fundamental biological processes and predominantly expressed during prenatal brain development. We additionally boost prediction of psychiatric disorders by conditioning independent GWAS on our multimodal multivariate GWAS. These findings shed light on the shared genetic mechanisms underlying variation in brain morphology, functional connectivity, and tissue composition.

Simple Score of Albumin and CRP Predicts High-Grade Toxicity in Patients with Multiple Myeloma Receiving CAR-T Therapy

Administration of chimeric-antigen receptor T-cell (CAR-T) therapy is complex and associated with unique toxicities. Identifying patients at risk for inferior outcomes is important for individualized management. The Glasgow-prognostic score (GPS) is a simple score shown to be highly prognostic of outcomes in the setting of traditional chemotherapy or checkpoint inhibitor administration. We sought to evaluate the value of the GPS to predict outcomes of patients with relapse refractory multiple myeloma (RRMM) receiving anti-BCMA CAR-T therapy. We included all patients treated with commercial CAR-T therapy for RRMM between 5/1/2021 and 2/1/2023 at the Moffitt Cancer Center. The GPS (CRP >1 mg/dL, 1 point; albumin <3.5, 1 point) was calculated for all patients at lymphodepletion (day -6) and patients were grouped as high-risk GPS (score = 2) or low-risk GPS (0 or 1). The primary endpoint was overall survival (OS) at day 100. A total of 139 pts were included, with a median follow-up of 6.7 months (95% CI, 6.2 to 8.9 months). Pts were treated with either idecabtagene vicleucel (83%) or ciltacabtagene autoleucel (17%). In total, 14% were classified with high-risk GPS, with significantly increased risk for grade 3 cytokine release syndrome (P = .003) and ICANS of any grade (P < .001). Patients in the high-risk GPS group had significantly lower day-100 OS (68.4% versus 97.3%, P < .001), OS at 6 months (56% versus 91.8% P = .0019) and PFS at 6 months (38.3% versus 72.3%, P = .03). The association of GPS with day-100 OS remained significant in a multivariable model. In conclusion, the GPS identifies a group of high-risk patients with RRMM receiving CAR-T therapy who experience increased rates of immune-mediated toxicity and are at higher risk for early mortality.

Assessing the Risk of Hypoglycemia Secondary to Propranolol Therapy for the Treatment of Supraventricular Tachycardia in Infants

Supraventricular tachycardia (SVT) is the most common arrhythmia among infants. Prevention of SVT is frequently managed through propranolol therapy. Hypoglycemia is a known adverse effect of propranolol therapy, but little research has been done on the incidence and risk of hypoglycemia in treatment of SVT in infants with propranolol. This study attempts to offer insight into the risk of hypoglycemia associated with propranolol therapy when treating infantile SVT to help inform future glucose screening guidelines. We conducted a retrospective chart review of infants treated with propranolol in our hospital system. Inclusion criteria were infants < 1 year of age who received propranolol for the treatment of SVT. A total of 63 patients were identified. Data was collected on sex, age, race, diagnosis, gestational age, nutrition source (Total Parenteral Nutrition (TPN) vs oral), weight (kg), weight for length (kg/cm), propranolol dose (mg/kg/day), comorbidities, and whether or not a hypoglycemic event was identified (< 60 mg/dL). Hypoglycemic events were identified in 9/63 (14.3%) patients. Of the patients with hypoglycemic events, 9/9 (88.9%) had comorbid conditions. Patients with hypoglycemic events had significantly lower weight and propranolol dose than those without hypoglycemic events. Weight for length also tended to increase risk for hypoglycemic events. The high incidence of comorbid conditions in the patients who had hypoglycemic events suggests that hypoglycemic monitoring may only be necessary in patients with conditions predisposing to hypoglycemia.

Cytomegalovirus viral load as predictor of the clinical course of hypoxic pneumonia in children

BACKGROUND: Children under 1 year of age with hypoxic pneumonia regularly have concurrent cytomegalovirus (CMV) viremia. In these children, the diagnosis of CMV-associated pneumonia and the prediction of an outcome are difficult. It is unclear whether quantification of blood CMV viral load (CMV-VL) can predict outcomes in these children.METHODS: This was a retrospective study including children (1-12 months of age), with detectable CMV-VL and hypoxic pneumonia admitted to the paediatric intensive care unit of Tygerberg Hospital, Cape Town, South Africa between 1 January 2014 and 31 December 2015. Clinical, radiological and biochemical data were collected.RESULTS: Of the 87 participants included (median age: 3.9 months, IQR 2.2-4.8), 35 were (40%) born prematurely. The median weight-for-age Z-score was -2.68 (IQR -3.0 to -0.83); 37 (43%) were severely underweight for age; 27 (31%) were HIV-positive, 3 were on ART. The median CMV-VL was log 4.0 (IQR 3.3-4.79); CMV_high was defined as CMV-VL > median; CMV-VL < median was classified as CMV_low. Overall survival was 90%; 12 (15.4%) remained oxygen-dependent at Day 28 post-admission. There was no difference in survival, 24-h post-admission ratio of arterial oxygen partial pressure to fractional inspired oxygen (P_aO₂:F_iO₂), oxygen dependence or ventilation duration between CMV_low and CMV_high. High-frequency oscillation ventilation duration was longer (P = 0.005) and Pneumocystis jirovecii (PJP) co-infection more frequent (P = 0.018) in CMV_high.CONCLUSION: CMV-VL is unable to predict the clinical outcome in children with hypoxic pneumonia. Specific treatment for CMV should be considered in all children at risk of CMV-associated pneumonia with detectable CMV-VL.

Exercise-induced engagement of the IL-15/IL-15Rα axis promotes anti-tumor immunity in pancreatic cancer

Aerobic exercise is associated with decreased cancer incidence and cancer-associated mortality. However, little is known about the effects of exercise on pancreatic ductal adenocarcinoma (PDA), a disease for which current therapeutic options are limited. Herein, we show that aerobic exercise reduces PDA tumor growth, by modulating systemic and intra-tumoral immunity. Mechanistically, exercise promotes immune mobilization and accumulation of tumor-infiltrating IL15Rα+ CD8 T cells, which are responsible for the tumor-protective effects. In clinical samples, an exercise-dependent increase of intra-tumoral CD8 T cells is also observed. Underscoring the translational potential of the interleukin (IL)-15/IL-15Rα axis, IL-15 super-agonist (NIZ985) treatment attenuates tumor growth, prolongs survival, and enhances sensitivity to chemotherapy. Finally, exercise or NIZ985 both sensitize pancreatic tumors to αPD-1, with improved anti-tumor and survival benefits. Collectively, our findings highlight the therapeutic potential of an exercise-oncology axis and identify IL-15 activation as a promising treatment strategy for this deadly disease.

Time-effectiveness and convenience of transvaginal ultrasound probe disinfection using ultraviolet vs chlorine dioxide multistep wipe system: prospective survey study

OBJECTIVES

To compare the efficiency, ease of use and user satisfaction of two methods of transvaginal ultrasound probe high-level disinfection: ultraviolet-C radiation (UV-C) and a chlorine dioxide multistep wipe system.

METHODS

This was a prospective survey study. UV-C units were introduced into a busy early pregnancy assessment service and compared with a multiwipe system for disinfection. Before seeing each patient, healthcare professionals (HCPs) measured with a stopwatch the time taken to complete a cycle of disinfection using either UV-C or chlorine dioxide multistep wipes and responded to a quick-response (QR) code-linked survey. Additional essential tasks that could be completed before seeing the next patient during probe disinfection were also documented. Using another QR code-linked survey, data on ease of use, satisfaction with the system used and preferred system were collected. The ease of use and satisfaction with the system were rated on a 0 to 10 Likert scale (0 poor, 10 excellent). A free-text section for comments was then completed.

RESULTS

Disinfection using UV-C (n = 331) was 60% faster than the chlorine dioxide multiwipe system (n = 332) (101 vs 250 s; P < 0.0001). A greater number of tasks were completed during probe disinfection when using UV-C, saving a further 74 s per patient (P < 0.0001). The HCPs using UV-C (n = 71) reported greater ease of use (median Likert score, 10 vs 3; P < 0.0001) and satisfaction (median Likert score, 10 vs 2; P < 0.0001) compared with those using the multiwipe system (n = 43). HCPs reported that the chlorine dioxide system was time-consuming and environmentally unfriendly, while the UV-C system was efficient and easy to use. Overall, 98% of the HCPs preferred using the UV-C system.

CONCLUSIONS

UV-C technology is more time-efficient and allows more essential tasks to be completed during disinfection. For a 4-h ultrasound list of 15 patients, the use of UV-C would save 55 min 45 s. HCPs found UV-C preferable and easier to use. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

P-698 Pituitary functioning gonadotroph adenomas (FGA)-induced ovarian hyperstimulation syndrome (OHSS): results from tertiary neuroendocrine centres in the UK

Study question

There are no published series of OHSS due to FGA. What FGA features should clinicians look for during OHSS, and what treatments are effective?

Summary answer

FGA tumour size is always &gt;10mm. Other pituitary hormones may be deficient. Surgical resection of FGA is an effective treatment for OHSS.

What is known already

Pituitary adenomas affect 1:1000 adults and are classified as functioning or non-functioning. Non-functioning pituitary adenomas do not secrete hormones, but most commonly stain histologically gonadotroph cells. Functional pituitary adenomas secrete hormones such as prolactin causing prolactinoma. However, it is rare for a pituitary tumour to cause clinical features of excessive gonadotrophins (functioning gonadotroph adenoma; FGA).

Single case reports, but no case series, have been published on the presentation of FGA-induced OHSS in women.

Surgical excision of adenomas has been reported to cause remission of symptoms, though systematic data are lacking owing to rarity of these tumours.

Study design, size, duration

National case series from tertiary neuroendocrine units in England, Wales and Scotland.

Participants/materials, setting, methods

Eight high-volume pituitary endocrine tertiary units within England, Wales and Scotland audited their records for any cases of FGA-induced OHSS; only seven patients have been identified to date. In all cases, there had been no recent exposure to assisted reproductive technologies (ART) or drugs known to induce OHSS including gonadotrophins or selective oestrogen receptor modulators (SERMS).

Main results and the role of chance

Seven cases of FGA were identified with mean age 31.6 years (range 16-48) at diagnosis. Two-of-seven women presented acutely unwell with abdominal pain, distention and palpable mass requiring oophorectomy for ovarian torsion/ruptured ovarian cyst. The remaining five women presented with abdominal pain (n = 2), thyrotoxicosis (n = 1), menstrual irregularities/galactorrhoea (n = 1) and visual disturbances (n = 1). All women experienced intermittent pelvic pain during medical attendance. Pelvic ultrasound demonstrated enlarged multiseptated ovaries (volume ranging 27-442cm3). Ascites was noted in one woman. Six women had visual field defects due to optic chiasm compression on formal assessment. Median FSH was 26.10 u/L (8.3-33), but LH was &lt;2.5 u/L in all cases. Estradiol (E2) far exceeded the reference range in 5/7 women (2990 to &gt; 18000pmol/L);E2 was at the upper limit of normal in the remaining 2/7 women (960-1450pmol/L). Hyperprolactinaemia, hyperthyroidism and other pituitary hormones deficiency were noted in 6/7, 1/7 and 4/7 women respectively. All FGAs were macroadenomas with diameters ranging 16-48mm. Two patients were administered a somatostatin analogue prior to surgery, but FSH, E2 and tumour size did not change. Transsphenoidal surgery was performed in 6/7 women, and always improved symptomatic and biochemical features of OHSS; however, residual FGA tumour was present post-operatively in all cases studied.

Limitations, reasons for caution

It is possible that some ‘non-functioning’ gonadotroph adenomas cause subclinical problems including menstrual irregularity and mild OHSS which were never diagnosed.

We have insufficient data to determine the prognosis for future pregnancy after FGA-induced OHSS.

This study utilised historical case-notes, so some data is missing.

Wider implications of the findings

The ‘spontaneous’ presentation of OHSS may be confusing for clinicians. We report that FGA is an important cause of spontaneous OHSS which has well-defined biochemical and radiological characteristics, which may be treated effectively in the short-to-medium with pituitary surgery. Results of this study may provide greater awareness of FGA-induced OHSS.

Ultrasound characteristics, serum biochemistry and outcome of ectopic pregnancies presenting during COVID-19 pandemic

OBJECTIVE

To describe and compare the characteristics of ectopic pregnancies (EPs) in the year prior to vs during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

This was a retrospective analysis of women diagnosed with an EP on transvaginal sonography conducted at a center in London, UK, providing early-pregnancy assessment, between 1 January 2019 and 31 December 2020. Women were identified via the Astraia ultrasound reporting system using coded and non-coded outcomes of EP or pregnancy outside the uterine cavity. Data related to predefined outcomes were collected using Astraia and Cerner electronic reporting systems. Main outcome measures included clinical, ultrasound and biochemical features of EP, in addition to reported complications and management.

RESULTS

There were 22 683 consultations over the 2-year period. Following consultation, a similar number and proportion of EPs were diagnosed in 2019 (141/12 657 (1%)) and 2020 (134/10 026 (1%)). Both cohorts were comparable in age, ethnicity, weight and method of conception. Gestational age at the first transvaginal sonography scan and at diagnosis were similar, and no difference in location, size or morphology of EP was found between the two cohorts. Serum human chorionic gonadotropin (hCG) levels at the time of EP diagnosis were higher in 2020 than in 2019 (1005 IU/L vs 665 IU/L; P = 0.03). The proportions of women according to type of final EP management were similar, but the rate of failed first-line management was higher during vs before the pandemic (16% vs 6%; P = 0.01). The rates of blood detected in the pelvis (hemoperitoneum) on ultrasound (23% vs 26%; P = 0.58) and of ruptured EP confirmed surgically (9% vs 3%; P = 0.07) were similar in 2019 vs 2020.

CONCLUSIONS

No difference was observed in the location, size, morphology or gestational age at the first ultrasound examination or at diagnosis of EP between women diagnosed before vs during the COVID-19 pandemic. Complication rates and final management strategy were also unchanged. However, hCG levels and the failure rate of first-line conservative management measures were higher during the pandemic. Our findings suggest that women continued to access appropriate care for EP during the COVID-19 pandemic, with no evidence of diagnostic delay or an increase in adverse outcome in our population. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Changes in physical activity associated with the COVID-19 pandemic in individuals with overweight and obesity: an interrupted time series analysis with historical controls

The objective of this study was to investigate changes in physical activity patterns associated with the COVID-19 pandemic in individuals with overweight and obesity who were participating in a school district worksite weight loss program. We conducted comparative design interrupted time series analyses on physical activity device (Fitbit) data from the 2018–2019 and 2019–2020 school years (N = 211). We administered a questionnaire in 2020 to supplement device data. After the stay-at-home orders in 2020, participants tended to decrease their weekly step count (B = −1315.7, SE = 627.7, p = .045), decrease their weekly “Lightly active minutes” (B = −39.1, SE = 12.6, p = .007), and increase their weekly “Very active minutes” compared to their counterparts from the year before (B = 7.6, SE = 3.2, p = .020). Decreased motivation, gym closures, and safety concerns were cited as barriers to physical activity. Having more time and health consciousness were cited as facilitators of physical activity. The COVID-19 pandemic was related to changes in physical activity in both positive and negative ways, revealing opportunities to promote healthy lifestyle behaviors in this population. More research is needed to determine optimal approaches to health promotion in the post-COVID-19 era.

333 Assessment of Spent Hemp Biomass as a Potential Feedstuff in Ruminant Diets

The 2018 Farm Bill removed hemp (Cannabis sativa) from the Controlled Substances Act, classifying it as an agricultural product. The process of cannabidiol extraction from hemp yields large quantities of spent hemp biomass (SHB) that may potentially be included in animal diets. However, the use of SHB in animal diets has not been approved by FDA yet since its effect on animal health, production and product quality is still unknown. Thus, a feeding study was carried out to investigate the effects of varying levels of SHB and a four-week withdrawal period on feed intake and liveweight gains of weaned lambs. A total of 35 weaned, male Polypay lambs kept in single pens were randomly assigned to five feeding treatments (n=7) and fed diets containing either no SHB (CON) or SHB at 10% (LH1) or 20% (HH1) for 4 weeks with 4 weeks withdrawal from SHB, or SHB at 10 (LH2) or 20% (HH2) for 8 weeks. The nutritive analysis of the SHB indicated a high-quality feed, with 20% (DM) crude protein and 27% NDF. Dry matter (DM) intake of lambs was negatively affected by 20% SHB during the first period. In the second period, DM intake was larger in lambs fed 10% SHB vs. CON, with the largest feed intake observed in HH1 lambs. In contrast, none of the performance data, including liveweight gains, were different across the groups and periods. Feeding 20% SHB decreased plasma cholesterol, NEFA, BHBA, Ca, and Cl and increased urea and Mg, while 10% SHB increased glucose, cholesterol, and NEFA. Our findings indicated that 10% SHB can be included in ruminant diets without causing any detrimental effect on performance with a possible positive effect on feed intake. The long-term feeding of 20% SHB strongly affects the metabolism.

The potential stickiness of pandemic-induced behavior changes in the United States

Human behavior is notoriously difficult to change, but a disruption of the magnitude of the COVID-19 pandemic has the potential to bring about long-term behavioral changes. During the pandemic, people have been forced to experience new ways of interacting, working, learning, shopping, traveling, and eating meals. A critical question going forward is how these experiences have actually changed preferences and habits in ways that might persist after the pandemic ends. Many observers have suggested theories about what the future will bring, but concrete evidence has been lacking. We present evidence on how much US adults expect their own postpandemic choices to differ from their prepandemic lifestyles in the areas of telecommuting, restaurant patronage, air travel, online shopping, transit use, car commuting, uptake of walking and biking, and home location. The analysis is based on a nationally representative survey dataset collected between July and October 2020. Key findings include that the "new normal" will feature a doubling of telecommuting, reduced air travel, and improved quality of life for some.

Use of active video games with or without videoconferencing on health outcomes in adolescent and young adult cancer survivors: a systematic review

PURPOSE

Adolescent and young adult (AYA) cancer survivors experience greater functional deficits compared to non-cancer peers or older survivors with a similar diagnosis. Physical activity (PA) is a key strategy for mitigating functional decline, and motivation and peer support are critical PA facilitators in AYA cancer survivors. Active video games (AVGs) may be a "gateway" method to promote PA. Further, integrating AVGs into group videoconferencing, a medium used by AYAs to socialize, can capitalize on peer support needed for PA motivation. Thus, we examined the use of AVGs and/or videoconferencing in PA interventions that included AYA survivors and the effect on physical function and health outcomes.

METHODS

Seven electronic databases were searched from incept to January 2020. Search terms included videoconferencing, video games, exercise, and cancer. The protocol is registered on PROSPERO: CRD42020163491. Two reviewers evaluated eligibility and methodological quality using Cochrane's risk of bias tools.

RESULTS

Six unique studies were included with 97% reviewer agreement. All used AVGs, none used videoconferencing alone, and one used both. Study designs and outcome measures were heterogeneous. Only one study solely targeted AYA survivors. Most were low to medium quality. Few showed significant improvements in quality of life (QOL) and fatigue (n=3), coordination/balance (n=2), and aerobic capacity (n=1).

CONCLUSIONS

PA interventions using AVGs and/or videoconferencing may improve QOL and fatigue, but evidence on function is lacking. Rigorous interventions targeting AYA survivors are needed.

IMPLICATIONS FOR CANCER SURVIVORS

Using AVGs and/or videoconferencing to facilitate PA may improve QOL and fatigue.

Patterns of self-monitoring technology use and weight loss in people with overweight or obesity

Mobile applications and paired devices allow individuals to self-monitor physical activity, dietary intake, and weight fluctuation concurrently. However, little is known regarding patterns of use of these self-monitoring technologies over time and their implications for weight loss. The objectives of this study were to identify distinct patterns of self-monitoring technology use and to investigate the associations between these patterns and weight change. We analyzed data from a 6-month weight loss intervention for school district employees with overweight or obesity (N = 225). We performed repeated measures latent profile analysis (RMLPA) to identify common patterns of self-monitoring technology use and used multiple linear regression to evaluate the relationship between self-monitoring technology use and weight change. RMLPA revealed four distinct profiles: minimal users (n = 65, 29% of sample), activity trackers (n = 124, 55%), dedicated all-around users (n = 25, 11%), and dedicated all-around users with exceptional food logging (n = 11, 5%). The dedicated all-around users with exceptional food logging lost the most weight (X2[1,225] = 5.27, p = .0217). Multiple linear regression revealed that, adjusting for covariates, only percentage of days of wireless weight scale use (B = -0.05, t(212) = -3.79, p < .001) was independently associated with weight loss. We identified distinct patterns in mHealth self-monitoring technology use for tracking weight loss behaviors. Self-monitoring of weight was most consistently linked to weight loss, while exceptional food logging characterized the group with the greatest weight loss. Weight loss interventions should promote self-monitoring of weight and consider encouraging food logging to individuals who have demonstrated consistent use of self-monitoring technologies.

Abstract 5281: An exercise intervention for pancreas cancer patients increases tumor vascularity

We and others have demonstrated in mice that moderate aerobic exercise remodels tumor vasculature and improves chemotherapy delivery. The sparse, dysfunctional vasculature in pancreatic ductal adenocarcinoma (PDAC) is one major barrier to delivering chemotherapy to the tumor. Improved vascular function and chemotherapy delivery could substantially improve patient survival over the current 7% rate. We first evaluated whether exercise might improve survival for patients with PDAC using a patient-derived xenograft (PDX) mouse model and moderate treadmill running. Treatment of PDX-bearing mice with gemcitabine or gemcitabine plus exercise caused tumor regression. However, gemcitabine was more effective when combined with exercise and excitingly, regrowth of tumors after treatment cessation was significantly delayed in mice treated with exercise combined with gemcitabine compared to gemcitabine alone. Our animal data suggests that exercise may be beneficial for patients with pancreatic cancer. However, it is unclear whether a sufficient level of exercise can be performed by patients with advanced cancers to achieve improved vascular function as predicted by animal studies. Recently, we completed a pilot study delivering a home-based aerobic and strength training exercise program (EP) to patients with potentially operable pancreas cancer. Fifty-eight patients (48% female, median age 66) completed the EP concurrent with chemotherapy or chemoradiation over a mean duration of 15 weeks prior to pancreatectomy. Participants completed a mean of 145.8 minutes of weekly moderate to vigorous physical activity. Surgical tumor specimens were obtained from 28 patients who participated in the EP, and were evaluated for the total number of vessels, vessel density, average number of open lumens, and number of elongated vessels. We found that tumors of patients who participated in the EP had significantly increased vessel density and a significantly increased number of elongated vessels compared to tumors from control patient, similar to our observations in mice. This is the first demonstration that an EP is feasible during the chemotherapy/ chemoradiation phases for pancreatic cancer patients, and importantly, that moderate exercise changes human tumor vascular biology. There was also a trend toward increased immune cell infiltration in tumors from patients who exercised. Cell death in tumors is being evaluated. This data suggests that exercise is a low-cost, low risk way to remodel human tumor vasculature and therefore may be an adjuvant to chemotherapy. Remodeled vasculature may increase chemotherapy delivery to the tumor, improving survival, as predicted in animal models. Further studies evaluating the impact of exercise on patient outcome as well as angiogenic biomarkers are underway.

The Effects of Neoadjuvant Axitinib on Anthropometric Parameters in Patients With Locally Advanced Non-metastatic Renal Cell Carcinoma

OBJECTIVE

To examine the effect that neoadjuvant axitinib for the treatment of localized renal cell carcinoma has on body compartment composition.

MATERIALS AND METHODS

The study was based on a single-institution, single-arm clinical trial that enrolled 24 patients with locally advanced non-metastatic biopsy-proven clear cell renal cell carcinoma. Patients received axitinib orally for up to 12 weeks. Computed tomography scans were completed before the start of treatment, after 7 weeks of treatment and at the completion of 12 weeks of treatment. Patients underwent nephrectomy after axitinib treatment. The primary outcome of the current study was change in body compartment composition. Secondary outcomes included development of new-onset sarcopenia and changes in body weight.

RESULTS

A total of 23 patients had a complete set of imaging for evaluation, of which 19 (82.6%) lost weight. Median weight loss was 4.5 kg (P <.001). Seven patients (30.4%) had sarcopenia before treatment, with an additional 5 (21.7%) developing sarcopenia during treatment. Median decrease in skeletal muscle was 2.9 cm²/m² (P <.001), visceral adipose tissue was 4.9 cm²/m² (P = .132), and subcutaneous adipose tissue was 1.0 cm²/m² (P = .043). Ten of the 16 patients (62.5%) without baseline sarcopenia achieved a partial response, whereas only 1 of the 7 patients (14.3%) with baseline pretreatment sarcopenia achieved a partial response (P = .069).

CONCLUSION

Neoadjuvant axitinib resulted in a decrease in skeletal muscle and subcutaneous adipose tissue, as well as weight loss. Patients with baseline sarcopenia tended to have a lower response rate to neoadjuvant axitinib.

Role of Fluorouracil, Doxorubicin, and Streptozocin Therapy in the Preoperative Treatment of Localized Pancreatic Neuroendocrine Tumors

INTRODUCTION

5-Fluorouracil, doxorubicin, and streptozocin (FAS) leads to a 39 % response rate in advanced pancreatic neuroendocrine tumors (pNETs). We sought to validate our hypothesis that preoperative FAS may facilitate resection of locoregionally advanced pNETs by reducing the anatomic extent of the primary tumor.

PATIENTS

All patients who received FAS between 2000 and 2012 as initial therapy for a localized pNET were reviewed. Tumor size and vascular relationships were compared on pretreatment and posttreatment imaging studies to quantify treatment response.

RESULTS

Twenty-nine patients received a median 4 cycles of FAS (range 2-15). Rates of RECIST progressive disease (PD), stable disease (SD), and partial response (PR) were 3, 90, and 7 %, respectively. An interface was observed between the tumor and a major mesenteric artery and/or vein in 19 (66 %) and 24 (83 %) patients, respectively; after therapy with FAS, 17 (59 %) and 22 (76 %) had persistent interface with artery and/or vein. Fourteen (48 %) patients underwent pancreatectomy, 7 (50 %) required vascular management, and 9 (64 %) operations were R0. The median overall survival of unresected and resected patients was 41 months (95 % CI, 16-66) and 112 months (95 % CI, 104-120) (P = 0.04).

CONCLUSIONS

Although patients receiving FAS for locoregionally advanced pNETs are unlikely to progress during systemic therapy, significant "downstaging" appears uncommon.

Development of the policy indicator checklist: a tool to identify and measure policies for calorie-dense foods and sugar-sweetened beverages across multiple settings

OBJECTIVES

We developed the policy indicator checklist (PIC) to identify and measure policies for calorie-dense foods and sugar-sweetened beverages to determine how policies are clustered across multiple settings.

METHODS

In 2012 and 2013 we used existing literature, policy documents, government recommendations, and instruments to identify key policies. We then developed the PIC to examine the policy environments across 3 settings (communities, schools, and early care and education centers) in 8 communities participating in the Childhood Obesity Research Demonstration Project.

RESULTS

Principal components analysis revealed 5 components related to calorie-dense food policies and 4 components related to sugar-sweetened beverage policies. Communities with higher youth and racial/ethnic minority populations tended to have fewer and weaker policy environments concerning calorie-dense foods and healthy foods and beverages.

CONCLUSIONS

The PIC was a helpful tool to identify policies that promote healthy food environments across multiple settings and to measure and compare the overall policy environments across communities. There is need for improved coordination across settings, particularly in areas with greater concentration of youths and racial/ethnic minority populations. Policies to support healthy eating are not equally distributed across communities, and disparities continue to exist in nutrition policies.

Childhood Obesity Research Demonstration project: cross-site evaluation methods

INTRODUCTION

The Childhood Obesity Research Demonstration (CORD) project links public health and primary care interventions in three projects described in detail in accompanying articles in this issue of Childhood Obesity. This article describes a comprehensive evaluation plan to determine the extent to which the CORD model is associated with changes in behavior, body weight, BMI, quality of life, and healthcare satisfaction in children 2-12 years of age.

DESIGN/METHODS

The CORD Evaluation Center (EC-CORD) will analyze the pooled data from three independent demonstration projects that each integrate public health and primary care childhood obesity interventions. An extensive set of common measures at the family, facility, and community levels were defined by consensus among the CORD projects and EC-CORD. Process evaluation will assess reach, dose delivered, and fidelity of intervention components. Impact evaluation will use a mixed linear models approach to account for heterogeneity among project-site populations and interventions. Sustainability evaluation will assess the potential for replicability, continuation of benefits beyond the funding period, institutionalization of the intervention activities, and community capacity to support ongoing program delivery. Finally, cost analyses will assess how much benefit can potentially be gained per dollar invested in programs based on the CORD model.

CONCLUSIONS

The keys to combining and analyzing data across multiple projects include the CORD model framework and common measures for the behavioral and health outcomes along with important covariates at the individual, setting, and community levels. The overall objective of the comprehensive evaluation will develop evidence-based recommendations for replicating and disseminating community-wide, integrated public health and primary care programs based on the CORD model.

Characterization of Anthropometric Changes that Occur During Neoadjuvant Therapy for Potentially Resectable Pancreatic Cancer

BACKGROUND

Little is known about changes in body composition that may occur during neoadjuvant therapy for pancreatic cancer. This study was designed to characterize these changes and their potential relationships with therapeutic outcomes.

METHODS

The study population consisted of patients with potentially resectable pancreatic cancer treated on a phase II trial of neoadjuvant chemotherapy and chemoradiation. Skeletal muscle and adipose tissue compartments were measured before and after administration of neoadjuvant therapy using SliceOMatic software (TomoVision, 2012) and protocol-mandated CT scans. Sarcopenia was defined using gender-adjusted norms.

RESULTS

Among 89 eligible patients, 46 (52 %) patients met anthropometric criteria for sarcopenia prior to the initiation of neoadjuvant therapy. Further depletion of skeletal muscle, visceral adipose tissue, and subcutaneous adipose tissue occurred during neoadjuvant therapy, but these losses did not preclude the performance of potentially curative surgery. Degree of skeletal muscle loss correlated with disease-free survival while visceral adipose loss was associated with overall and progression-free survival. However, completion of all therapy, including pancreatectomy, was the only independently significant predictor of outcome in a multivariate analysis of overall survival.

DISCUSSION

These data suggest that body composition analysis of standard CT images may provide clinically relevant information for patients with potentially resectable pancreatic cancer who receive neoadjuvant therapy. Anthropometric changes must be considered in the design of preoperative therapy regimens, and further efforts should focus on maintenance of muscle and visceral adipose tissue in the preoperative setting.

Staffing benchmarks: a model for determining how many security officers are enough

The authors describe the development of a model which assists with answering the question, "for a facility with certain characteristics, what would be the industry average number of security FTE's?" Through the use of multiple regression analysis using actual field data, an objective means of making this determination is possible, they report.

A meta-analysis into the effect of lateral-wedged insoles with subtalar strapping versus traditional insoles in adults with medial knee osteoarthritis

To  systematically  identify,  collate,  and  analyze  the  current available evidence  for  the  effectiveness  of  lateral-wedged  insoles,  with subtalar strapping,  on  reducing  pain,  improving  function  and  improving  the femoral-tibial  angle  (FTA),  in  adults  with  medial  knee osteoarthritis compared to traditional insoles without subtalar strapping.Six computerised databases, namely Cochrane Library, CiNAHL, PEDro, BIOMED central,  PubMed  and  ScienceDirect  were  searched. The  included articles were  then  all  rated  using  the  PEDro  scale  to  determine  their meth-odological quality.  Homogeneous data were pooled in a meta-analysis using Review Manager (REVMAN) software.  Where statistical pooling of the results was not possible, findings were summarised in narrative form. Three randomised controlled trials were selected for this review. The average PEDro score was 5.7. A meta-analysis demonstrated that lateral-wedged insoles with subtalar strapping significantly reduced pain in the short-term (p=0.004). The review found that lateral-wedge insoles with subtalar strapping significantly decreased pain in the short-term and seemed to have a positive effect on the FTA in the long-term, when compared to traditional insoles without  subtalar strapping. The lateral-wedge insole with subtalar strapping may provide a financially feasible adjunctive self-management treatment for knee OA and should be considered before invasive procedures such as surgery.

Mitochondrial uncoupling protein 2 in pancreatic β-cells

Pancreatic β-cells have remarkable bioenergetics in which increased glucose supply upregulates the cytosolic ATP/ADP ratio and increases insulin secretion. This arrangement allows glucose-stimulated insulin secretion (GSIS) to be regulated by the coupling efficiency of oxidative phosphorylation. Uncoupling protein 2 (UCP2) modulates coupling efficiency and may regulate GSIS. Initial measurements of GSIS and glucose tolerance in Ucp2(-/-) mice supported this model, but recent studies show confounding effects of genetic background. Importantly, however, the enhancement of GSIS is robustly recapitulated with acute UCP2 knockdown in INS-1E insulinoma cells. UCP2 protein level in these cells is dynamically regulated, over at least a fourfold concentration range, by rapid proteolysis (half-life less than 1 h) opposing regulated gene transcription and mRNA translation. Degradation is catalysed by the cytosolic proteasome in an unprecedented pathway that is currently known to act only on UCP2 and UCP3. Evidence for proteasomal turnover of UCP2 includes sensitivity of degradation to classic proteasome inhibitors in cells, and reconstitution of degradation in vitro in mitochondria incubated with ubiquitin and the cytosolic 26S proteasome. These dynamic changes in UCP2 content may provide a fine level of control over GSIS in β-cells.

T cell pathways involving CTLA4 contribute to a model of acute lung injury

Acute lung injury (ALI) is a frequent pulmonary complication in critically ill patients. We characterized a murine model of LPS-induced ALI, focusing on Th cells. Following LPS administration, bronchoalveolar lavage lymphocytes, neutrophils, IL-6, TNF-alpha, and albumin were increased. Analysis of LPS-induced T cells revealed increased Th cell-associated cytokines (IL-17A, -17F, and -22), as well as increased expression of CD69 (a cell activation marker), Foxp3, and CTLA4 in CD4(+) T cells. Administration of anti-CTLA4 Ab decreased LPS-induced bronchoalveolar lavage albumin and IL-17A, while increasing CD4(+)Foxp3(+) cell number and Foxp3 expression in CD4(+)Foxp3(+) cells. These data suggest that pulmonary LPS administration promotes CD4(+) T cells and that T cell pathways involving CTLA4 contribute to ALI.

A photographic method for estimating wear of coal tar sealcoat from parking lots

Coal-tar-based sealcoat has been recognized as an important source of PAHs to the environment through wear and transport via stormwater runoff. Sealcoat removal rates have not been measured or even estimated in the literature due to the complex array of physical and chemical process involved. A photographic study was conducted that incorporates all sources of wear using 10 coal tar-sealed parking lots in Austin, Texas, with sealcoat age ranging from 0 to 5 years. Randomly located photographs from each parking lot were analyzed digitally to quantify black sealed areas vs lighter colored unsealed areas at the pixel level. The results indicate that coal tar sealcoat wears off of the driving areas of parking lots at a rate of approximately 4.7% per year, and from the parking areas of the lots at a rate of approximately 1.4% per year. The overall annual loss of sealcoat was calculated at 2.4%. This results in an annual delivery to the environment of 0.51 g of PAHs per m2 of coal tar-sealed parking lot. These values provide a more robust and much higher estimate of loading of PAHs from coal tar sealcoated parking lots when compared to other available measures.

Positional relationship between leg rotation and lumbar spine during quiet standing

Healthcare professionals frequently evaluate spinal posture on visual assessment during the clinical examination. While this visual assessment of the spine has been shown to be unreliable, the use of a plumbline as to aid clinical visual assessment has also been reported. There is a "normal" sagittal contour that functions quite well in healthy people. It positions the head in space, it protects the neural axis, and it allows efficient, pain-free motion. Lumbar lordosis is routinely evaluated in most spine patients, but what constitutes a normal sagittal contour is less well defined. A key component of normal sagittal contour is lumbar lordosis. Changes in the lumbar lordosis frequently occur in pathological gait, usually in association with alterations in pelvic tilt, and commonly as a compensation for a limited range of flexion/extension at the hip joint. Recent investigations looked at the effect of hyperpronation on pelvic alignment in a standing position and supported the existence of a kinematic chain in healthy subjects, where hyperpronation can lead to an immediate shank and thigh internal rotation and change in pelvic position. While there is a wealth of research is available on the effectiveness of functional foot orthoses, the present investigation reports the effect of pronated foot position on the lumbar region of the back by employing an optoelectronic movement analysis system.

Evidence of cardiac autonomic neuropathy in dogs with diabetes mellitus

The NeuroScope, a specific and sensitive indicator of cardiac vagal tone, was used to look for differences in autonomic tone between 25 dogs with naturally occurring diabetes mellitus and 23 healthy control dogs, to determine whether there was any correlation between the dogs' cardiac vagal tone, the duration of diabetes and the adequacy of glycaemic control. The cardiac index of parasympathetic activity (cipa) was determined for each dog over a period of 2600 heartbeats. The mean, median and modal cipa values were significantly lower in the diabetic dogs than in the healthy dogs. There was no significant relationship between the cipa values and the duration of disease or the adequacy of recent glycaemic control in the diabetic dogs, but there was a significant inverse relationship between the cipa values and the bodyweight of the diabetic dogs that was not evident in the normal dogs. The conclusions were based on a 500-heartbeat interval selected from the 2600 heartbeats recorded.

Gene expression in the axolotl germ line: Axdazl, Axvh, Axoct-4, and Axkit

Primordial germ cells (PGCs) in embryos of mammals and urodele amphibians are formed by induction in the absence of germ plasm. We describe expression of four germ cell-related genes through the germ cell cycle of the axolotl. The orthologs of vasa and daz-like are up-regulated in PGCs of tail bud embryos before the gonad forms and are expressed throughout the female germ cell cycle. Mammalian Oct-4 is a marker of pluripotency in embryonic cells. Axolotl Oct-4 has higher homology to Oct-4 than that found in other vertebrates. It is expressed in the equivalent of the mouse epiblast, in the posterior mesoderm of late gastrulae that gives rise to PGCs, and in diplotene growing oocytes, but not in presumptive PGCs after gastrulation. Finally, a c-kit homolog is expressed in gonadal oogonia and growing oocytes as in mice but is also not found in PGCs. The expression pattern in urodele gonadal germ cells is similar to that of other vertebrates, although the pattern in pregonadal PGCs is distinctly different from that of mice. We conclude that PGCs are restricted to the germ line later in urodeles than in mice or lack migration and proliferation programs.

Communication skills training in postgraduate medicine: the development of a new course

It has long been accepted that communication is of central importance in healthcare, and a core aspect of clinical competence. Many educational institutions and Royal Colleges now reflect this and consider communication skills a priority in postgraduate examination. The new examination "Practical Assessment of Clinical and Examination Skills" has replaced the Royal College of Physicians MRCP part 2 clinical and oral examination. This examination now consists of five clinical stations, two of which focus on communication skills. A short course for postgraduate trainees has been designed to address the communication skills requirements of the part 2 clinical examination. The aims, development, and content of the course are described. Emphasis is placed on candidates practising skills with patients and receiving feedback during the course. Evidence suggests that practice with feedback is an essential ingredient of communication skills courses, and is more effective than other methods such as observing experts or video examples, or simply discussing issues in communication. Results of a preliminary evaluation indicate that the course was perceived as valuable by candidates and that the aims, format, and content were appropriate. Although the preliminary evaluation was largely positive, it could be argued that the acid test of the effectiveness of a course is an objective evaluation of skills, observed before and after the course, a development that is being considered for future evaluation of the course. Recommendations for applying this type of training to postgraduate trainees in any branch of medicine are given.

Severe sporotrichoid infection with Mycobacterium szulgai

Mycobacterium szulgai is a nontuberculous, acid-fast bacillus or atypical mycobacteria, which prior to 1972 was not thought of as a pathogen. Since then most cases reported in the literature have been of pulmonary disease with only a few case reports of cutaneous disease. Our patient, who had an underlying, uncategorized, immunosuppressive condition, presented with multiple severe ulcers spreading proximally up the arms in a sporotrichoid pattern with more scatttered lesions on his legs. He made a full recovery with appropriate antimicrobial treatment.

Isolex 300i CD34-selected cells to support multiple cycles of high-dose therapy

BACKGROUND

We have previously reported that repeated cycles of high-dose therapy (HDT), can be supported by unmanipulated autologous PBPC. Here we investigate whether purified CD34+ cells, obtained by immunomagnetic separation using the Isolex 300i device, can support such therapy.

METHODS

Twenty-nine consecutive patients with metastatic breast cancer had PBPC mobilized and harvested following chemotherapy and G-CSF (10 microg/kg per day). Patients with > 4.0 x 10(6)/kg CD34+ cells in the apheresis product underwent CD34-selection using the Isolex 300i (v2.0) device. All cells collected were equally divided into three aliquots and cryopreserved. Patients who did not achieve this threshold had unmanipulated cells collected and stored. Patients subsequently received three cycles of HDT with paclitaxel (175 mg/m2), thiotepa (300 mg/m2) and either ifosfamide (10 g/m2) or cyclophosphamide (4 g/m2). It was intended for patients to receive CD34-selected cells to support each of the three cycles of HDT (i.e 1/3 for each cycle) and to compare hemopoietic recovery between patients receiving CD34-selected cells or unmanipulated cells.

RESULTS

Thirteen of the 29 patients (45%) did not mobilize sufficient CD34+ cells to undergo CD34-selection. The remaining 16 patients underwent CD34-selection with a median purity of 84.3% (range: 16.3-96.1%) and yield of 34% (range: 1-60%). Fifteen of these patients proceeded to HDT and 42 of the planned 45 cycles were administered. Nine patients had all three HDT cycles supported by CD34-selected cells. The median number of CD34-selected cells (x 10(6)/kg) infused per cycle was 1.5 (range: 0.04-3.01). Three of the 15 patients required infusion of 'back-up' unmanipulated cells because of delayed neutrophil recovery. Of the 13 patients whose PBPCs did not undergo CD34+ cell selection, 11 proceeded to HDT with a median of 3.2 x 10(6)/kg (range: 2.0-4.4) unselected cells infused per cycle and 31 of 33 planned cycles were delivered. When hemopoietic recovery was compared between cycles of HDT supported by CD34-selected (n = 34) and unmanipulated cells (n = 31), there was a modest slowing in the patients receiving CD34-selected cells; time to ANC > 1.0 x 10(9)/L = 11 days versus 10 days (P = 0.0122) and platelets > 20 x 10(9)/L = 14 days versus 13 days (P = 0.0009). No difference in recovery to 50 x 10(9)/L was observed (P = 0.54).

CONCLUSION

We have demonstrated that Isolex 300i CD34-selected cells are capable of supporting multiple cycles of HDT. However, we were unable to acquire sufficient CD34+ cells to perform this processing in 45% (13/29) of patients and further improvements in yield are required to overcome the modest delay in neutrophil and platelet recovery.

Frequency and clinical implications of fluid dynamically significant diffuse coronary artery disease manifest as graded, longitudinal, base-to-apex myocardial perfusion abnormalities by noninvasive positron emission tomography

BACKGROUND

Diffuse coronary atherosclerosis is the substrate for plaque rupture and coronary events. Therefore, in patients with mild arteriographic coronary artery disease without significant segmental dipyridamole-induced myocardial perfusion defects, we tested the hypothesis that fluid dynamically significant diffuse coronary artery narrowing is frequently manifest as a graded, longitudinal, base-to-apex myocardial perfusion abnormality by noninvasive PET.

METHODS AND RESULTS

In this study, 1001 patients with documented coronary artery disease by coronary arteriography showing any visible coronary artery narrowing underwent rest-dipyridamole PET perfusion imaging. Quantitative severity of dipyridamole-induced, circumscribed, segmental PET perfusion defects was objectively measured by automated software as the minimum quadrant average relative activity indicating localized flow limiting stenoses. Quantitative severity of the graded, longitudinal, base-to-apex myocardial perfusion gradient indicating fluid dynamic effects of diffuse coronary artery narrowing was objectively measured by automated software as the spatial slope of relative activity along the cardiac longitudinal axis.

CONCLUSIONS

In patients with mild arteriographic disease without statistically significant dipyridamole-induced segmental myocardial perfusion defects caused by flow-limiting stenoses compared with normal control subjects, there was a graded, longitudinal, base-to-apex myocardial perfusion gradient significantly different from normal control subjects (P=0. 001) that was also observed for moderate to severe dipyridamole-induced segmental perfusion defects (P=0.0001), indicating diffuse disease underlying segmental perfusion defects; 43% of patients with or without segmental perfusion defects demonstrated graded, longitudinal, base-to-apex perfusion abnormalities beyond +/-2 SD of normal control subjects, indicating diffuse coronary arterial narrowing by noninvasive PET perfusion imaging.

Improving continuity of care across psychiatric and emergency services: combining patient data within a participatory action research framework

Presented with the concerns of emergency department nurses about providing appropriate and co-ordinated care for patients seeking mental health services, a Monash University School of Nursing, Victoria, Australia, research team chose a participatory action research strategy. Jointly executed with staff from the Peninsula Health Care Network, the research process brought together in a number of fora multiple disciplines involved in the care and management of psychiatric patients. The participatory action research process itself was the first step in remedial action. Through it, participants and management gained a firmer view of the issues facing Frankston Hospital Emergency Department staff in dealing with psychiatric patients, and in securing their access to suitable pathways of care. Other research outcomes included: a compilation of summary statistics showing patterns of use by psychiatric patients of Frankston Hospital's Emergency Department; beginning discussions about pathways of care for these patients; and the development of a screening tool to be used by the triage nurse for at-risk psychiatric patients presenting to the Emergency Department.
