RESUMEN
BACKGROUND & AIMS: Weight loss and malnutrition are frequent problems in oncology patients. The aim of this study was to get a perspective of the current practice of parenteral nutrition (PN) care in an outpatient setting and to improve patient-centered nutritional care. METHODS: Fifty-three outpatient oncology centers participated in this observational study performed between July 2010 and March 2011. All participating centers entered data online into a web-based documentation form, containing a number of oncology patients, diagnoses, and detailed data about oncology patients receiving PN. RESULTS: Two cohorts were analyzed. First cohort consisted of all oncology patients in quarter 04/2010. Second cohort consisted of patients with PN during the whole studying period. In the first cohort 2.46% (n = 626) of 25,424 oncology patients received PN. Most frequent diagnoses of patients receiving PN were gastric cancer (n = 119) and colorectal cancer (n = 104), however most stated diagnosis was "other" (n = 163). In the second cohort (n = 1137), a common indication for PN was impaired gastrointestinal passage (n = 177), although here again most stated reason was "other" (n = 924). In the course of the PN treatment, patients (n = 1137) showed a stable or slowly increasing body mass index (from 21.6 ± 3.8 kg/m(2) to 21.8 ± 3.5 kg/m(2)). CONCLUSION: This is the largest study outlining the characteristics of oncology patients in the context of PN in German ambulatory centers. They confirm the important role of PN in the care of gastrointestinal cancer. Further studies have to be performed to identify if other indications than those mentioned in relevant guidelines can trigger initiation of PN.

WHAT IS KNOWN AND OBJECTIVE: Good communication between hospital and primary care physicians (PCPs) is important for the continuity of patient care in the transition phase following hospital treatment. Drug-related problems and medication errors may occur at that interface. Discharge letters often lack a structured medication report at the end and therefore may not provide the reasons for medication changes, resulting in low adherence rates. The objectives were to develop a structured medication report as part of the discharge letter, to evaluate the impact of the medication report in ischaemic stroke patients and to identify the most important issues in the transitional care process of stroke patients. METHODS: First, a structured medication report was developed. Thereafter, the impact of this new medication report on clinical practice was evaluated with an open, prospective, interventional two-phase study conducted at the Klinikum Fulda gAG (Germany), which included patients with ischaemic stroke and >2 drugs in the discharge medication. In the control group (CG), the neurologist included the current medication in the discharge letter. In the intervention group (IG), the clinical pharmacist added the detailed information to a medication report. To evaluate adherence to discharge medication, the PCP was interviewed 3 months after hospital discharge about the medication. Adherence was measured with respect to the entire medication regimen, antithrombotic and cholesterol-lowering drugs and discontinued medication. The most important issues in the transitional care for patients with ischaemic stroke were identified on the basis of the secondary stroke prevention and cardiovascular risk factors. RESULTS AND DISCUSSION: Overall, 312 patients were enrolled in the study with 156 patients in each group. By providing detailed information in the newly developed discharge letter, adherence increased significantly from 83·3% (CG) to 90·9% (IG; P = 0·01). Significant differences between the CG and IG were found with regard to adherence to both antithrombotic drugs [83·8% CG vs. 91·9% IG (P = 0·033)] and statin therapy [69·8% CG vs. 87·7% IG (P < 0·001)]. WHAT IS NEW AND CONCLUSION: The use of a structured medication report as part of the discharge letter leads to improved adherence to hospital discharge medication.

WHAT IS KNOWN AND OBJECTIVE: Identifying, preventing and resolving drug-related problems (DRP) is an important issue in the pharmaceutical care process. Because DRPs have been detected in a more systematic way, the need for a classification system to document, classify and evaluate the collected data has become necessary. The objective was to develop a classification system for DRPs within the hospital setting, to evaluate the practicality and to assess the inter-rater reliability. METHODS: All DRPs defined in PI-Doc and PCNE, which are relevant in the hospital setting, were included. Further relevant DRPs identified in other projects in a hospital setting as well as DRPs from the daily work on the ward were collected, and a short description of each DRP was written. A prospective study was conducted at Klinikum Fulda, Germany, in both a non-surgical and a surgical setting to explore whether the new classification system is suitable to classify DRPs in clinics with different specifications. For assessing the inter-rater reliability, 24 standardized case reports were provided. All participants classified them independently. The inter-rater reliability was analysed using Kappa coefficient. RESULTS AND DISCUSSION: A classification system for DRPs in the hospital setting (APS-Doc) was established with 10 main categories and 48 subcategories. Practicality was assessed in 250 patients in a non-surgical ward as well as in 100 patients in a surgical ward. The inter-rater agreement was 0·68 (95% CI, 0·66-0·69) for main categories, which comprises substantial agreement. Moderate agreement (κ = 0·58; 95% CI, 0·58-0·59) was demonstrated for the subcategories. WHAT IS NEW AND CONCLUSION: A new hierarchical classification system for DRPs in the hospital setting has been developed. APS-Doc seems suitable for various parts of the medication process such as medication reconciliation and drug therapy within both non-surgical and surgical wards. Inter-rater reliability was found to be substantial in the main categories and moderate in the subcategories.

BACKGROUND AND AIM: Surgical site infections (SSIs) are associated with a high morbidity, mortality and healthcare costs. The prevention of SSIs is based on a combination of preoperative preparation, surgical techniques, perioperative antibiotic prophylaxis (PAP) and postoperative wound care. Despite an abundance of evidence demonstrating the effectiveness of antimicrobials to prevent SSIs, the use of antimicrobial prophylaxis in this clinical setting is associated with inappropriate timing and selection and excessive duration of administration. To date, pharmacy interns (PIs) have not been involved in this process. The aim of this study was to evaluate feasibility of involving PIs in monitoring adherence to the guidelines for antibiotic prophylaxis in surgery patients. METHODS: The study was conducted in seven hospitals in Germany within the framework of the project "Pharmacy interns on the ward" (P-STAT2). Twenty-seven PIs participated, either from either May to October 2008 or from November 2008 to April 2009. Each patient admitted to the participating wards was consecutively monitored. PIs documented the antibiotic prophylaxis and checked the adherence with the hospital ward's PAP guidelines taking both the choice of antibiotic drug and the duration of PAP into account. The costs of antibiotics, personnel and material were calculated in cases of non-adherence with guidelines. RESULTS: This is the first time that PIs were involved in monitoring antibiotic prophylaxis guidelines. A total of 6,167 patients were enrolled (mean age 58.3 ± 19.6 years; 47.1% male); of these, 5,064 patients underwent surgery and were ultimately available for evaluation. Guidelines for antibiotic prophylaxis were followed in 70.7% of the cases. CONCLUSIONS: The study revealed that many patients do not receive the appropriate antibiotic prophylaxis despite the fact that guidelines are in place. Based on these results, we conclude that PIs may play an important role in antibiotic prophylaxis management.

PN (parenteral nutrition) should be standardised to ensure quality and to reduce complications, and it should be carried out in consultation with a specialised nutrition support team whenever possible. Interdisciplinary nutrition support teams should be established in all hospitals because effectiveness and efficiency in the implementation of PN are increased. The tasks of the team include improvements of quality of care as well as enhancing the benefit to cost ratio. Therapeutic decisions must be taken by attending physicians, who should collaborate with the nutrition support team. "All-in-One" bags are generally preferred for PN in hospitals and may be industrially manufactured, industrially manufactured with the necessity to add micronutrients, or be prepared "on-demand" within or outside the hospital according to a standardised or individual composition and under consideration of sterile and aseptic conditions. A standardised procedure should be established for introduction and advancement of enteral or oral nutrition. Home PN may be indicated if the expected duration of when PN exceeds 4 weeks. Home PN is a well established method for providing long-term PN, which should be indicated by the attending physician and be reviewed by the nutrition support team. The care of home PN patients should be standardised whenever possible. The indication for home PN should be regularly reviewed during the course of PN.

BACKGROUND: The detection of cerebrospinal fluid fistulas in the region of the anterior or lateral skull base can be difficult. The fluorescein test with lumbar administration of 5% sodium fluorescein solution can be used to detect cerebrospinal fluid leakage, identify weak points in the dura, achieve precise localisation of cerebrospinal fluid fistulas and to check intraoperatively that watertight dural closure has been achieved. However, use of the test is problematic as the fluorescein solution used is not licensed for this indication in Germany and severe neurological complications are described in the literature. In order to clarify the legal situation regarding use of the test, we therefore analysed the complications occurring in a sizeable patient sample. METHOD: The records of all patients in whom a fluorescein test had been performed between 1979 and June 2000 were analysed retrospectively for the occurrence of complications. RESULTS: The most frequent complication in the 368 fluorescein tests performed was headache, followed by nausea and vomiting, temperature elevation, dizziness and nuchal pain. These side-effects were no more frequent than described for lumbar puncture alone. Twenty-six patients experienced side-effects on the day of the operation, 65 on the first postoperative day, 36 on the second day, 34 on the third day and 13 patients after the third day. There were two cases of grand mal seizures following concomitant intrathecal contrast medium administration. None of the patients had side effects persisting longer than 4 weeks. CONCLUSIONS: Intrathecal administration of a 5 % fluorescein solution is a safe procedure provided that the maximum dosages are not exceeded and the solution is prepared and administered correctly and in accordance with the specified indications and contraindications. In view of its great diagnostic benefit and low risk when properly used, the dictates of therapeutic freedom allow use of this drug despite the fact that it is not licensed for this purpose in Germany. It is necessary to obtain written informed consent from the patient.

Topical corticosteroids are one of the main pillars in the treatment of nasal polyps. The exact topography of their intranasal deposition has not yet been adequately visualised. The intranasal distribution of a 1% sodium fluorescein solution applied with original Pulmicort Topinasal (budesonide) metered pump bottles was analysed by videoendoscopy. The study group included eight healthy subjects and ten patients who had undergone endonasal sinus surgery. Videoendoscopy was performed in the study group within the first minute after application of the fluorescein solution. Additionally the deposition pattern of Pulmicort Topinasal was analyzed using a nasal model. The examination showed that the majority of the substance is deposited on the anterior portion of the nasal septum and the head of the inferior turbinate. Only a small fraction actually reaches the middle meatus. The distribution is improved by application during the decongested phase of the nasal cycle, after use of vasoconstricting nasal drops and maintaining a spraying angle of 45 degrees upwards. The development of new delivery techniques and systems could improve the efficacy of intranasally administered corticosteroids and reduce the complication rate.

Isolated hepatocytes were prepared from rat liver by collagenase perfusion and density gradient centrifugation. The hepatocyte preparation released angiotensinogen at a basal rate of 50-120 pmol/g wet weight per h. Release was linear with time for at least 4 h. Angiotensinogen secretion was reduced in the presence of actinomycin D, and inhibited by cycloheximide, puromycin, colchicine and vinblastine. In the presence of tunicamycin, an inhibitor of N-glycosylation, the secretion of angiotensinogen as well as total protein and albumin secretion were diminished. Hepatocytes from nephrectomized rats exhibit an increased secretion rate of angiotensinogen, whereas total protein secretion was unaltered. Preincubation of hepatocytes with hydrocortisone (0.1 mM) or angiotensin II (10 nM) induced an increase of angiotensinogen release. There was no concomitant increase of total protein or albumin secretion, indicating that these effects are not the expression of a general stimulation of protein synthesis and secretion.

Chronic treatment with converting enzyme inhibitors induces a fall of plasma angiotensinogen concentration, which is thought to result from increased consumption by renin. As this explanation cannot account for all the observations, we reexamined this effect. Rats received captopril (50 mg/kg per day), enalapril (10 mg/kg per day) or Hoe 498 (1 mg/kg per day) for 7 days. Plasma angiotensinogen (by indirect assay) fell to 34, 37 and 43% of its initial values, respectively. Total immunoreactive angiotensinogen (by direct radioimmunoassay, which also measures des-AI-angiotensinogen) was 76, 70 and 95% of the initial values, respectively. This suggests that a major part of the fall of intact angiotensinogen can be attributed to increased cleavage by renin, but an additional factor is likely to be involved. Experiments with isolated hepatocytes indicated that converting enzyme inhibitors in high concentrations may have a direct effect on angiotensinogen secretion. Whether this can account for the fall in total immunoreactive angiotensinogen in vivo remain unclear.
