Preference for the fixed-dose combination of pertuzumab and trastuzumab for subcutaneous injection in patients with HER2-positive early breast cancer (PHranceSCa): A randomised, open-label phase II study.

AIM: The aim of the study was to assess patient preference for the fixed-dose combination of pertuzumab and trastuzumab for subcutaneous injection (PH FDC SC) in patients with HER2-positive early breast cancer in PHranceSCa (NCT03674112). MATERIALS AND METHODS: Patients who completed neoadjuvant P + H + chemotherapy + surgery were randomised 1:1 to three intravenous (IV) P + H cycles followed by three cycles of PH FDC SC or vice versa (crossover) and then chose subcutaneous (SC) injection or IV infusion to continue up to 18 cycles (continuation). Assessments were via patient and healthcare professional (HCP) questionnaires. RESULTS: One hundred and sixty patients were randomised (cut-off: 24 February 2020); 136 (85.0%, 95% confidence interval: 78.5-90.2%) preferred SC; 22 (13.8%) preferred IV; 2 (1.3%) had no preference. The main reasons for SC preference were reduced clinic time (n = 119) and comfort during administration (n = 73). One hundred and forty-one patients (88.1%) were very satisfied/satisfied with SC injection versus 108 (67.5%) with IV infusion; 86.9% chose PH FDC SC continuation. HCP perceptions of median patient treatment room time ranged from 33.0-50.0 min with SC and 130.0-300.0 min with IV. Most adverse events (AEs) were grade 1/2 (no 4/5s); serious AE rates were low. AE rates before and after switching were similar (cycles 1-3 IV → cycles 4-6 SC: 77.5% → 72.5%; cycles 1-3 SC → cycles 4-6 IV: 77.5% → 63.8%). CONCLUSION: Most patients strongly preferred PH FDC SC over P + H IV. PH FDC SC was generally well tolerated, with no new safety signals (even when switching), and offers a quicker alternative to IV infusion.

Attitudes and Opinions of Adolescent Females Regarding 2 Methods of Bladder Filling for Transabdominal Ultrasound: A Q-Sort Study.

OBJECTIVES: Adolescent female patients who are not sexually active and who present to a pediatric emergency department with abdominal pain require a full bladder prior to transabdominal ultrasound. Procedures to fill the bladder are largely institution or provider dependent. We examined adolescent females' attitudes and opinions toward 2 common methods of bladder filling, intravenous fluid administration and transurethral Foley catheter placement, by means of a Q-sort study. METHODS: Two convenience samples of adolescent female patients in the pediatric emergency department at an academic children's hospital participated in the study. In part 1, subjects underwent a semistructured interview to elicit their opinions regarding 2 methods of bladder filling: intravenous fluid or transurethral catheter. The summation of subject statements was then narrowed down to a final Q set of 25 statements. In part 2, a second sample of subjects independently arranged this Q set according to their own agreement or disagreement with each statement. Principal components analysis was conducted to examine factors or collections of statements representing a shared viewpoint and to describe commonalities. RESULTS: Part 1 was completed with 9 subjects, and part 2 with 26 subjects. Factors revealed from the Q-sort data included acceptance of tests deemed medically necessary, desire for parental involvement, and a wish to minimize discomfort. Most adolescents aligned with 1 of these 3 factors. CONCLUSIONS: Adolescent female patients varied in their attitudes and opinions regarding intravenous catheter hydration and Foley catheter placement for transabdominal ultrasound. Knowledge of adolescent viewpoints may help better inform practitioner-patient communication for this procedure.

Psychosocial and Demographic Characteristics of Children and Adolescents With Headache Presenting for Treatment in a Headache Infusion Center.

BACKGROUND: Approximately 10% of pediatric patients have recurrent headaches, with migraine being the most common headache type. If untreated, migraine may progress to status migrainosus, a debilitating condition of prolonged duration, high pain severity, and significant disability. There is high variability in the treatment of status migrainosus including medications used and treatment setting, which may occur in the emergency room, as an inpatient admission, or, less often, in an outpatient infusion center. The paucity of research on the treatment of status migrainosus is a limitation to treatment effectiveness. OBJECTIVE: The objective of the study was twofold. First, we sought to examine the demographic characteristics of children and adolescents accessing our outpatient infusion center for prolonged headache. Second, we sought to determine whether any demographic or psychosocial differences exist between patients who access infusion therapy compared to patients who do not access infusion therapy for their headaches. METHODS: We conducted a retrospective chart review of all patients between the ages of 6 and 19 years who were treated in our outpatient headache infusion center. A subset of these patients completed a behavioral health evaluation (treatment group) and they were compared to a control group of similar age (birthdate within 6 months) and gender to patients not seeking infusion treatment. Variables of interest included patient demographics, headache type and characteristics, and scores on the Pediatric Quality of Life Inventory (PedsQL), Functional Disability Inventory (FDI), Pediatric Pain Coping Inventory (PPCI), and the Behavior Assessment System for Children - Second Edition (BASC-2). RESULTS: A total of 284 patients were included in the study (n = 227 receiving infusion treatment and n = 57 controls). Patients were primarily female (224/286; 78.9%), Caucasian (254/286; 90.1%), and had a mean age of 15 years. Findings suggest a promising difference in the PPCI Distraction subscale, χ2 (1) = 3.7, P = .054, with a mean rank score of 61.90 for the treatment group and 50.21 for the control group. Additionally, a statistically significant difference was noted on the Social Support subscale, χ2 (1) = 10.6, P = .001, with a mean rank score of 65.92 for the treatment group and 46.26 for the control group. Results also indicated a statistically significant difference in disability scores, χ2 (1) = 10.0, P = .002, with a mean rank FDI score of 66.83 for the treatment group and 47.34 for the control group. Patients in the infusion group also reported lower quality of life on the PedsQL Total score (F[1, 109] = 5.0, P = .028; partial η2  = 0.044), and on the Physical (F[1, 109] = 7.9, P = .006; partial η2  = 0.069) and School (F[1, 109] = 4.6, P = .035; partial η2  = 0.041) subscales. No significant differences were found on the BASC-2. Parent reported data also revealed a significantly higher level of disability among patients seeking infusion treatment compared to the non-infusion group χ2 (1) = 11.7, P = .001. However, there were no significant differences on the PedsQL, PPCI, or BASC-2. CONCLUSIONS: Our findings support the disabling nature of migraine among children and adolescents, with higher levels of disability and lower quality of life reported in the group of patients utilizing infusion treatment. Developing concrete treatment plans and goals combined with bio-behavioral therapy are necessary to reduce functional disability and increase quality of life among these patients. Awareness of this patient group's pain-related coping strategies may help health care providers tailor treatment recommendations and develop or refine cognitive-behavioral headache treatment techniques.

Brinquedo terapêutico instrucional: preparando a criança para a quimioterapia endovenosa / Instructional Therapeutic Toy: preparing child for Intravenous Chemotherapy

Introdução: O câncer merece destaque entre as doenças que causam transtornos em adultos e crianças, pois continua sendo um diagnóstico dos mais temidos da atualidade. Vincula-se a um estigma de sofrimento, mutilação e morte, envolvendo uma série de ameaças e dificuldades, que afetam não só a criança, mas sua família como um todo, ao longo do processo de diagnóstico e tratamento Objetivo: Comparar os comportamentos de crianças durante a quimioterapia endovenosa antes e após a aplicação do brinquedo terapêutico instrucional (BTI). Materiais e Métodos: Pesquisa não controlada do tipo "antes e depois", realizada na oncopediatria de um hospital público. Foram avaliadas 10 crianças submetidas a quimioterapia endovenosa. Na coleta de dados, utilizou-se um questionário com questões sociodemográficas, clínicas, comportamentais e reações esboçadas durante o tratamento, antes e após a sessão de BTI. A análise de dados foi feita no programa SPSS, sendo realizado o teste de Mc Nemar, considerando um intervalo de confiança de 95%. Resultados: O câncer infantil mais frequente foi a Leucemia Linfoide Aguda (40%). Dos comportamentos analisados, percebeuse redução significativa após o uso do BTI do comportamento "postura retraída". Conclusão: O BTI representou uma ferramenta importante no controle da ansiedade e sofrimento gerado pelo tratamento quimioterápico endovenoso.

Introduction: Cancer plays a notable role among diseases that afflict adults and children. Its diagnosis is still much feared and connects to a stigma of suffering, mutilation and death. It is related to difficulties and treats that affects not only the child but also his whole family during the long process of diagnosis and treatment. Objective: to compare the behaviors of children during intravenous chemotherapy before and after the application of therapeutic instructional toy (BTI). Materials and methods: Uncontrolled search such as "before and after", held in oncopediatria of a public hospital. Ten children were evaluated, subjected to intravenous chemotherapy. For collection, it was used a questionnaire asking for sociodemographic, clinical and behavioral questions, as well as issues and reactions outlined during treatment, before and after the session of BTI. The data analysis was done in SPSS program, being carried out the Mc Nemar test, assuming a confidence interval of 95%. Results: the most frequent childhood cancer was Acute Lymphoblastic leukemia (40%). Among the behaviors examined, it was significantly reduced after the use of BTI "retracted posture" behavior. Conclusion: the BTI represented an important tool in the control of anxiety and suffering generated by intravenous chemotherapy treatment.

The Effects of Child Life Specialists on Success Rates of Intravenous Cannulation.

BACKGROUND: Child life specialists (CLS) work with children directly to minimize long-term psychological sequelae of traumatic or medical events such as intravenous cannulation. There has been little done to measure how CLS impact outcomes of medical procedures. The objective of this study is to determine the impact of interventions by CLS upon successful attainment of intravenous (IV) cannulation among pediatric patients in the emergency department setting. METHOD: This was an eight month retrospective review within an urban tertiary-care freestanding pediatric Emergency Department (ED), using nursing and CLS documentation of ED patients younger than 21years who underwent IV cannulation. CLS self selected which children received procedural support, and the duration of CLS staffing was not a full 24h. Children with CLS documentation were compared against those without documented interventions by CLS. IV cannulation success and number of IV cannulation attempts were the primary outcomes. Confounding variables such as location of intravenous site, intravenous gauge, and professional qualifications were added. Chi-square determined the impact of CLS on primary outcomes. Logistic regression examined the association between successful IV cannulation with age. RESULTS: In all, 5460 children had documented IV cannulation, and 240 of those received CLS intervention. CLS intervention was not associated with IV cannulation success (p=0.5). The only significant association for successful IV cannulation was intravenous site (p<0.001). There was no interaction effect between patient age and CLS (p=0.12). CONCLUSION: Interventions by CLS do not affect the procedural outcome of intravenous cannulation success. Benefits of CLS are likely better measured in psychological impact of anxiolysis and improved experience, rather than in procedural outcome.

Matching doses of distraction with child risk for distress during a medical procedure: a randomized clinical trial.

BACKGROUND: Parents often want to provide support to their children during medical procedures, but not all parents are effective in providing distraction after brief training. OBJECTIVE: The aim of this study was to investigate the effects of three doses of distraction intervention for children at high and medium risk for procedure-related distress. METHODS: Children undergoing scheduled intravenous insertions for diagnostic or treatment purposes and their parents participated. A computerized application, Children, Parents and Distraction, was used to predict distress risk. Doses of intervention were basic (parents trained on providing distraction), enhanced (basic training plus tailored instructions, environmental modifications, and support and guidance from the research assistant), and professional (a trained research assistant provided distraction). Outcome measures were Observational Scale of Behavioral Distress-Revised for behavioral distress, Oucher for self-reported pain, parent report of child distress, and salivary cortisol for physiological distress. RESULTS: A total of 574 children, ages 4-10, and their parents participated. The Children, Parents and Distraction predicted that the risk for distress was high for 156 children, medium for 372, and low for 46. Children predicted to have higher risk for distress displayed more behavioral distress (p < .01). Children in the medium-risk group who had the professional intervention displayed significantly less behavioral distress (p < .001). Children in the high-risk group tended to have less behavioral distress when receiving the professional intervention (p = .07). There were no significant group differences for self-report of pain, parent report of distress, or cortisol levels. DISCUSSION: Some parents may need additional training in providing distraction to their children during procedures, and some children at medium and high risk for distress may need professional support. Parents should be asked about their preferences in acting as the distraction coach and, if willing, be provided as much training and support as possible in the clinical situation.

Parents' attitudes toward oral rehydration therapy in children with mild-to-moderate dehydration.

OBJECTIVE: According to current guidelines, the first line of treatment for mild-to-moderate dehydration is oral rehydration; the second line is rehydration through a nasogastric tube. Both methods are widely underused. This study was conducted to evaluate parents' attitudes towards rehydration methods used in pediatric emergency departments. DESIGN: 100 questionnaires were distributed to parents of children who visited emergency room due to gastroenteritis and suspected dehydration. RESULTS: 75 of the parents expected their child to get IV fluids. 49 of them would refuse to consider oral rehydration. 75 of the parents would refuse to consider insertion of nasogastric tube. Parents whose children were previously treated intravenously tended to be less likely to agree to oral treatment. Parents were more prone to decline oral rehydration if the main measurement of dehydration was the child's clinical appearance, clinical appearance with vomiting, or child's refusal to drink and were more likely to agree if the main measurement was diarrhea, diarrhea with clinical appearance, or clinical personnel opinion. CONCLUSIONS: This is the first study to examine parents' expectations. We found that in the majority of cases, parents' expectations contradict current guidelines. Efforts should be taken to educate parents in order to allow full implementation of the guidelines.

Health care provider and caregiver preferences regarding nasogastric and intravenous rehydration.

OBJECTIVE: Despite evidence supporting its use, nasogastric rehydration is rarely used in North America. We conducted a prospective, cross-sectional, 3-phase study to evaluate current perspectives. METHODS: We compared the proportions of respondents in favor of nasogastric (as opposed to intravenous) rehydration, should oral rehydration fail, between clinicians and caregivers. Phase 1: caregivers of children aged 3 to 48 months, who presented to a Canadian pediatric emergency department with symptoms of gastroenteritis, were invited to complete a survey. Phase 2: phase 1 participants administered intravenous or nasogastric rehydration had the procedure observed and outcome data recorded. Phase 3: pediatric emergency medicine physicians, fellows, and nurses completed a survey. RESULTS: Four hundred thirty-five children-parent dyads and 113 health care providers participated. If oral rehydration were to fail, 10% (47 of 435) of caregivers and 14% (16 of 113) of clinicians would choose nasogastric rehydration (difference = 3.4%; 95% confidence interval: -2.8 to 11.4). Caregivers were more familiar with the term intravenous than nasogastric rehydration (80% vs 20%; P < .001). Sixty-four children (15%) received intravenous rehydration; none received nasogastric rehydration. Participating nurses have inserted 90 (interquartile range: 25-150) intravenous cannulas compared with 4 (interquartile range: 2-10) nasogastric tubes during the preceding 6 months (P < .001). After a brief educational intervention, the proportion recommending nasogastric rehydration increased to 27% (117 of 435) among caregivers (P < .001) and 43% (49 of 113) among health care providers (P < .001). CONCLUSIONS: In keeping with caregiver desires, health care providers in a Canadian emergency department employ intravenous rehydration when oral rehydration fails. Enhanced change management strategies will be required for nasogastric rehydration to become adopted in this environment.

Postoperative ambulation in thoracic surgery patients: standard versus modern ambulation methods.

AIM: A single-subject study of two methods of postoperative ambulation of patients recovering from thoracic surgery. BACKGROUND: During the postoperative setting, patients are often burdened by their condition that reduces their ability to ambulate. This problem is compounded by the addition of devices that make walking more cumbersome. To simplify the process of ambulation during the postoperative period, an intravenous pole/walker (IVPW) was specifically designed to allow all patient devices and attachments to accompany the patient during ambulation, without the need for supplemental caregiver assistance. METHODS: The IVPW method of ambulation was compared with standard method of ambulation (SMA) in a single-subject clinical trial. Thirty-nine consecutive thoracic surgery patients with at least an IV and chest tube were ambulated using alternatively either the IVPW or the SMA. Immediately following the ambulation periods, the patient and patient's health care worker assessed both methods using satisfaction surveys consisting of several questions about the episodes of ambulation and the number of health care workers needed to assist during ambulation. RESULTS: Patient satisfaction was significantly higher in the ability of the IVPW to provide support and assist in ambulation in comparison with the SMA (p < 0·001). Nurses felt the IVPW both facilitated and provided a safer method for ambulation compared with the SMA (p < 0·001). On average, one less employee was required during ambulation with the IVPW (p < 0·001). CONCLUSION: The IVPW provided better support and was perceived as a safer method for ambulation compared with the SMA. The IVPW also required one less person to assist with ambulation. RELEVANCE TO CLINICAL PRACTICE: Facilitation of ambulation in the postoperative setting can impact nursing care and patient satisfaction.

[Experimental prospective cognitive study on the evaluation of connection of fatigue perception and depression among caregivers and team treating cancer patients receiving oral chemotherapy to systemic chemotherapy. Equi-Car 10 study]. / Studio sperimentale prospettico conoscitivo di valutazione della relazione della percezione di fatigue e depressione tra caregiver, equipe curante e pazienti oncologici in trattamento chemioterapico con terapie somministrate per via orale verso terapie somministrate per via sistemica Studio Equipe-Caregivers 10 (Studio Equi-Car 10).

OBJECTIVE: The Equi-Car 10 is an spontaneous, observational study. The objective was to assess the connection of fatigue perception and depression of caregivers, oncological team and oncological patients in oral chemotherapy to intravenous METHOD: The study recruited 60 patients and 60 caregivers. The study was carried out on patients with lung, breast and colon cancer requiring chemotherapy, and family members were chosen as caregivers. Patients, caregivers and doctors filled in FACT-F and Zung questionnaires at the opening day of the medical record, after three and six cycles of chemotherapy, and three months after the end of the treatment. RESULTS: The Zung depression and Functional Assessment of Cancer therapy-Fatigue (FACT-F) showed: (a) on patients treated with intravenous therapy showed significantly higher levels of fatigue and depression than those of patients treated with oral therapy, even when the latter were treated for advanced disease; (b) on caregivers of patients treated with systemically administered therapies showed elevated levels of Fatigue and depression which proved to be significantly higher than those of caregivers of patients treated with oral therapies, even when treated for advanced disease; (c) on three oncologist has highlighted low levels of Fatigue and depression, for both types of patients, higher for patients with systemic therapy related to the management of side effects. CONCLUSIONS: The results showed that cancer patients and caregivers have high levels of fatigue and depression both related to the disease stage and to the mode of drug administration. It is necessary to provide cancer patients and caregivers with appropriate psychological support and preventive programs for secondary and relapse prevention.

Salivary cortisol responsivity to an intravenous catheter insertion in children with attention-deficit/hyperactivity disorder.

OBJECTIVE: To compare salivary cortisol baseline levels and responsivity as well as behavioral distress to intravenous (IV) catheter insertions in 4- to 10-year-old children with (n = 29) and without (n = 339) attention-deficit/hyperactivity disorder (ADHD). METHODS: This is a secondary data analysis from a sample of 542 children who participated in a multisite study on distraction. Data included were demographic variables, Pediatric Behavior Scale-30, Observational Scale of Behavioral Distress-Revised, and four salivary cortisol samples. RESULTS: Home samples from the ADHD group revealed nonsignificant but higher cortisol levels than the non-ADHD group. However, on the clinic day, the ADHD group had significantly lower cortisol levels before (0.184 vs. 0.261, p = .040) and 20-30 min after IV insertion (0.186 vs. 0.299, p = .014) compared with the non-ADHD group. CONCLUSIONS: Cortisol levels in children with and without ADHD differ in response to the stress of an IV insertion.

The preferences and experiences of different bisphosphonate treatments in women with breast cancer.

OBJECTIVE: The objective of this study was to examine women's experiences with oral and intravenous (i.v.) bisphosphonate therapy, the impact that treatment had on bone pain and Quality of Life (QoL), and their preferences if choice were available between oral and i.v. administration. METHODS: This was a prospective study of women with metastatic breast cancer receiving either oral or i.v. bisphosphonate therapy. Semi-structured interview techniques and QoL questionnaires were employed. Participants in the study were interviewed three times, once in person and twice by telephone. RESULTS: A total of 79 patients from eight UK hospitals participated in the study; 35 were receiving oral bisphosphonate medication and 44 i.v. treatments. Self-reported adherence to oral therapy was good although 21% had chosen not to take their drugs at some time. Most had adapted their lifestyle to accommodate oral therapy with 29/37(74%) completely satisfied. However 9/37(24%) expressed dissatisfaction with constraints especially the time required to stand upright after taking their tablets. By 6 months 23/25 (91%) of patients receiving (i.v.) therapies were generally satisfied with the frequency and 22/25 (88%) with the convenience especially if given concurrently with chemotherapy. Overall 25/54 (46%) patients reported improved bone pain scores on the validated FACT-BP scale from baseline to 6 months. CONCLUSIONS: Both oral and i.v. therapies have disadvantages but were acceptable to most patients some of whom had reduced bone pain over time. More data regarding acceptability, adherence, and patients' preference for bisphosphonate therapies are required. Until randomised trials demonstrate superior efficacy for one mode of bisphosphonate therapy over another, we suggest offering patients a choice of bisphosphonate therapy.

Percutaneous lines for delivering intravenous antibiotics in people with cystic fibrosis.

BACKGROUND: Percutaneous long lines (long intravenous lines) and short intravenous lines (also termed cannulae) are both used to deliver intravenous antibiotics in cystic fibrosis to treat respiratory exacerbations of the disease. The perceived advantage of a long intravenous line is a greater duration of line function, which has to be balanced against a technically more challenging insertion procedure, and the possibility of more discomfort on insertion. OBJECTIVES: To compare long intravenous lines with short intravenous lines in people with cystic fibrosis receiving intravenous antibiotics, in terms of lifespan of the line, ease of insertion, complication rates of the line and patient satisfaction. This will help patients and clinicians choose between devices. SEARCH STRATEGY: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of most recent search: 26 August 2010. SELECTION CRITERIA: Randomised studies comparing long intravenous lines lines with short intravenous lines or comparing different types of long intravenous lines. DATA COLLECTION AND ANALYSIS: We identified two studies, one comparing long intravenous lines with short intravenous lines, and one comparing two different types of long intravenous lines. MAIN RESULTS: Two studies (67 participants) were included in the review. Based on the published reports, both studies had potential for bias in several domains. There is some evidence that long intravenous lines are superior to short intravenous lines. One study of 20 participants found that the lifespan of a long intravenous line is longer than that of a short intravenous line, and that participants preferred the long intravenous lines to short intravenous lines. A further study of 47 participants found no difference in lifespan, or participant preference when comparing two different long intravenous lines (the Hydrocath and Vygon EC). Neither study was powered to detect differences in serious complications of the devices. AUTHORS' CONCLUSIONS: There is some evidence to support the use of long intravenous lines rather than short intravenous lines, in terms of lifespan of the line and patient satisfaction. There is no evidence to suggest that any one type of long intravenous line is superior, and currently choice of line should be determined by operator and patient preference. There are numerous devices available which are used in cystic fibrosis. Further research is required to identify clinically important differences between these devices.

[Search for the subconsciousness of hospital pharmacists on their practices of blood drawing or injection, and etc].

The purpose of this study was to clarify the subconsciousness of hospital pharmacists regarding them practicing drip infusion or blood drawing for therapeutic drug monitoring (TDM), etc. We conducted a mail-in survey targeting 476 randomly-selected hospital pharmacists. In our survey sheet we presented our "hypothetical condition" i.e., "that medical practices such as drip infusion or blood drawing for TDM by hospital pharmacists be legally allowed" and we asked them 23 items about the pros and cons of this hypothetical condition and its influence on medical practice. Then, using factor analysis, we searched for the subconsciousness of hospital pharmacists from their answers to the 23 items. We then analyzed the causal association between the factors extracted from the survey and the pros and cons of the "hypothetical condition" using logistic regression analysis. 47.7% of respondents agreed to the "hypothetical condition". The results of this research provided 5 factors, consisting of "expectation of medical care and society", "temperament of pharmacists", "pharmacotherapy", "employment", and "medical team". We understood from the result of logistic regression analysis that hospital pharmacists subconsciously had two kinds of expectation, i.e., expectation about medical care and society, and about qualitative improvement of pharmacotherapy, as their background when they decided to agree to themselves practicing drip infusion or blood drawing for TDM, etc.

Post-oral infusion sites that support glucose-conditioned flavor preferences in rats.

Rats learn to prefer a flavored solution (CS+) paired with a gastrointestinal glucose infusion over an alternate flavor (CS-) paired with a non-caloric infusion. Prior work implicates a post-gastric site of glucose action, which is the focus of this study. In Exp. 1, male rats (8-10/group) were infused in the duodenum (ID), mid-jejunum (IJ), or distal ileum (II) with 8% glucose or water as they drank saccharin-sweetened CS+ and CS- solutions, respectively, in one-bottle 30-min sessions. Two-bottle tests (no infusions) were followed by a second train-test cycle. By the second test, the ID and IJ groups preferred the CS+ (69%, 67%) to the CS- but the II group did not (48%). Satiation tests showed that ID and IJ infusions of glucose reduced intake of a palatable solution similarly, while II infusions were ineffective. In Exp. 2, rats (10/group) drank CS solutions in one-bottle, 30-min sessions and were given 2-h ID or hepatic portal vein (HP) infusions. The CS+ and CS- were paired with 10 ml infusions of 10% glucose and 0.9% saline, respectively. Following 8 training sessions, the ID group preferred the CS+ (67%) to the CS- but the HP group did not (47%) in a two-bottle test. The similar CS+ preferences displayed by ID and IJ, but not II groups implicate the jejunum as a critical site for glucose-conditioned preferences. A pre-absorptive glucose action is indicated by the CS+ preference displayed by ID but not HP rats in Exp. 2. Our data were obtained with non-nutritive CS solutions. HP glucose infusions are reported to condition preferences for a flavored food that itself has pre- and post-absorptive actions. Thus, there may be multiple sites for glucose conditioning with the upper or mid-intestines being the first site of action.

Patients' assessment of the convenience of fentanyl HCl iontophoretic transdermal system (ITS) versus morphine intravenous patient-controlled analgesia (IV PCA) in the management of postoperative pain after major surgery.

The patient-controlled fentanyl HCl iontophoretic transdermal system (ITS) is a compact, self-contained, needle-free system that has been approved for acute postoperative pain management in hospitalized adults. The objective of the present analysis was to evaluate patients' assessment of fentanyl ITS and morphine intravenous patient-controlled analgesia (IV PCA) convenience on 7 different subscales, using a validated patient ease of care (EOC) questionnaire in 2 prospective, open-label, randomized, phase IIIb clinical trials. Patients received fentanyl ITS or morphine IV PCA (N = 1,305) for up to 72 h after total hip replacement surgery (THR study) or abdominal or pelvic surgery (APS study). For the majority of items on the patient EOC questionnaire, trends suggest that greater percentages of patients reported the most positive response for fentanyl ITS than they did for morphine IV PCA in both studies; differences were particularly noteworthy for items on the Movement subscale. In the THR study, more patients in the fentanyl ITS group were responders compared with those in the morphine IV PCA group for the subscales Confidence with Device, Pain Control, Knowledge/Understanding, and Satisfaction. In the APS study, responder rates for these subscales did not differ between treatment groups. These findings indicate that patients assessed the EOC associated with fentanyl ITS higher compared with morphine IV PCA for the management of acute postoperative pain and suggest that fentanyl ITS has the potential to improve acute postoperative pain care for patients and nurses.
