Psychological impact of multigene cancer panel testing in patients with a clinical suspicion of hereditary cancer across Spain.

OBJECTIVE: Patients' psychological reactions to multigene cancer panel testing might differ compared with the single-gene testing reactions because of the complexity and uncertainty associated with the different possible results. Understanding patients' preferences and psychological impact of multigene panel testing is important to adapt the genetic counselling model. METHODS: One hundred eighty-seven unrelated patients with clinical suspicion of hereditary cancer undergoing a 25-gene panel test completed questionnaires after pretest genetic counselling and at 1 week, 3 months, and 12 months after results to elicit their preferences regarding results disclosure and to measure their cancer worry and testing-specific distress and uncertainty. RESULTS: A pathogenic variant was identified in 38 patients (34 high penetrance and 4 moderate penetrance variants), and 54 patients had at least one variant of uncertain significance. Overall, cancer panel testing was not associated with an increase in cancer worry after results disclosure (P value = .87). Twelve months after results, carriers of a moderate penetrance variant had higher distress and uncertainty scores compared with carriers of high penetrance variants. Cancer worry prior to genetic testing predicted genetic testing specific distress after results, especially at long term (P value <.001). Most of the patients reported the wish to know all genetic results. CONCLUSIONS: Our results suggest that patients can psychologically cope with cancer panel testing, but distress and uncertainty observed in carriers of moderate penetrance cancer variants in this cohort warrant further research.

Parenteral nutrition supplemented with glutamine in patients undergoing bone marrow transplantation.

UNLABELLED: The objective of the study is to evaluate if the administration of glutamine in parenteral nutrition (PN) solution reduces the need for antibiotics, the risk of liver disease and the duration of hospital stay in bone marrow transplantation. MATERIAL AND METHODS: Retrospective observational study in 68 adult patients undergoing a bone marrow transplantation who required PN for mucositis. Of these patients, 40 were given PN with 2,063 +/- 294 kcal/day and 98.6 +/- 13.9 g of amino acids/day, supplemented with Lglutamine (13.5-27 g/day), and 28 were given isocaloric (1,966 +/- 307 kcal/day) and isonitrogenated (92 +/- 16.3 g of amino acids/day) PN with standard glutamine-free amino acid solution. Antibiotic consumption and duration of hospital stay were analysed. Of the total cohort, hepatic profile was studied at the beginning and on day 7 of PN in 50 patients without liver disease at the start of PN. RESULTS: There were no differences between both groups with regard to total number and duration of antibiotics prescribed or hospital stay. Of the 50 patients without hepatic alterations at the beginning of PN, 2 patients in the control group and 5 in the glutamine group developed a hepatic profile compatible with liver disease secondary to PN. Comparing both groups, there were no differences in hepatic enzyme values. CONCLUSIONS: Supplementation with PN glutamine does not improve the variables studied, but the actual clinical use of glutamine in this haematological treatment should be studied further and its potential advantages identified.

[Vitamins stability in parenteral nutrition]. / Estabilidad de vitaminas en nutrición parenteral.

OBJECTIVE: Some decades ago, several studies were published describing vitamins degradation in parenteral nutrition (PN) and their catalysis by oligoelements such as copper. Thus, the practice of administering oligoelements and vitamins every other day and adding them the same day of PN was implemented. Today, in many Spanish hospitals these recommendations are still being followed although currently different products, type of containers, and ways of administration are used. The purpose of this review is to determine whether combined administration of vitamins and oligoelements with PN is recommended and how many days they remain stable while refrigerated under the current conditions of preparation and administration of PN. SETTING: We have reviewed the articles on vitamins stability in PN published after 1990. RESULTS: The results are controversial with vitamin A, although "all-in-one" administration and photo-protection remarkably decrease its degradation and there seems to be no difference between adding the vitamin before its administration and doing so previously. Vitamin E is stable with photo-protection for 3-7 days under refrigeration plus one additional day at room temperature if multilayered bags are used. Thiamine is stable if bisulfites-free amino acids solutions are used. CONCLUSIONS: We conclude that vitamins and oligoelements may be administered together and PN be prepared before use if "all-in-one" photo-protected multilayered bags and bisulfite-free amino acids solutions are used.

Upper gastrointestinal findings detected by capsule endoscopy in obscure gastrointestinal bleeding.

OBJECTIVE: We analyzed our experience with the use of capsule endoscopy in areas that can be explored with gastroscopy to justify obscure bleeding, as well as the outcome after a new recommended gastroscopy in order to determine if a second gastroscopy before the capsule study can provide any benefit in the management of this disease. METHODS: We retrospectively studied 82 patients who were explored with capsule endoscopy for obscure gastrointestinal bleeding who had undergone previously only one gastroscopy. Findings in the zones which were accessible by gastroscopy were normal, mild/known and severe/unknown. In the latter cases we recommended a second gastroscopy, and their treatment and outcome were subjected to further study. RESULTS: Capsule endoscopy did not find any unknown esophageal findings. In 63% of cases, no gastric or duodenal lesions were shown; in 20%, lesions were mild or had been previously diagnosed, and in 17%, a new gastroscopy was recommended due to the discovery of an unknown condition which could be the cause of the obscure bleeding. This new information brought about a change in treatment for 78% of patients in this group, all of whom improved from their illness. Capsule endoscopy found significant intercurrent alterations in the small intestine in only 14% of cases. CONCLUSIONS: The performance of a second gastroscopy, previous to capsule endoscopy, in the study of obscure gastrointestinal bleeding can offer benefits in diagnostic terms and may introduce therapeutic changes. A detailed analysis of the upper tract frames in intestinal capsule endoscopy studies is mandatory since it may provide relevant information with clinical impact on the management of these patients.

[Intervention of a pharmacy department following the 11-M terrorist attack]. / Actuación de un servicio de farmacia en el atentado terrorista del 11-M.

OBJECTIVE: To describe the intervention of a pharmacy department, as well as medication requirements, in the healthcare emergency situation brought about by the terrorist attack of March 11, 2004 in Madrid. To compare this intervention with other similar experiences reported in the medical literature. METHOD: A compilation of actions carried out by pharmacists directly involved in the management of this incident. A literature search of Medline, Cochrane Library, and Spanish Index Medicus databases. RESULTS: The pharmacy department acted to ensure the availability of all medication needed in the management of casualties by placing urgent orders in pharmaceutical laboratories, simplifying distribution networks, and staying in permanent contact with the medical and nursing staff of the emergency department, as well as with people in charge of emergency coordination. Most commonly used medications included plasma expanders, fluid therapy, blood-derived products, pain killers, antiseptics, peripheral myorelaxants, and antibiotics, which are consistent with those employed by other Madrid hospitals for this same attack. CONCLUSIONS: The pharmacy department, as any other department in a hospital, should be ready to rapidly and effectively cope with any emergency situation. Having a protocol available including major intervention guidelines is advisable to reduce reaction times, anticipate potential complications, and effectively solve such situations.

Effectiveness of low-dose intramuscular anti-VHB immune globulin in the prophylaxis of viral B hepatitis reinfection after liver transplantation: preliminary report.

INTRODUCTION: Prophylaxis using high-dose intravenous anti-HBV immune globulin (HBIG) is effective to prevent reinfection due to hepatitis B virus (HBV) after orthotopic liver transplantation (OLT). However, this treatment is expensive and intravenous administration is difficult during outpatient care. Our aim was to assess the effectiveness of low-dose intramuscular HBIG to prevent HBV reinfection after OLT. PATIENTS: Six patients (all men, mean age 41 years, negative HBV DNA without hepatotropic virus coinfection) were transplanted in our institution due to HBV cirrhosis and included in a prospective noncomparative study. Intramuscular HBIG (2000 IU) was administered during the anhepatic phase of OLT, followed by daily 2000 IU doses for 7 days and then monthly. HBV antibody titers were measured every month. Reinfection was defined as the recurrence of surface HBV antigen in serum after transplantation. RESULTS: After 1 year follow-up, none of the six patients had detectable HBV surface antigen and the liver biopsies were normal in all cases. Using 2000 IU, anti-HBs levels were: 880+/-356 IU/L at 1 month, 191+/-123 at 6 months, and 225+/-49 after 1 year. In all cases anti-HBs titers were above 100 IU/L during the follow-up. CONCLUSIONS: Monthly administration of low-dose (2000 IU) intramuscular HBIG effectively prevents recurrence of HBV infection as well as attains a protective level of anti-HBs antibodies (over 100 IU/L) for at least the first year after transplantation.

[Catheter management in parenteral nutrition]. / Estudio sobre manejo de catéteres en nutrición parenteral.

Following the appearance of Staphylococcus epidermidis positive hemocultures in four patients undergoing parenteral nutrition in different services, and after microbiological controls of the mixtures prepared by the Pharmacy Service in order to discard contamination during preparation, it was decided to assess the handling o catheters and central pathways by the Hospital Nursing Staff. A survey was carried out of 34 nurses, 17 each from the morning and evening shifts, from the floors with patients undergoing parenteral nutrition, representing 13.3% of all the nurses of those floors. There were five sections in the survey, with fifty-two questions referring to the introduction of catheters, change of dressing, care of the point of insertion, uses of the administrative pathway, change and handling of the parenteral nutrition bag, intravenous administration of medicines and parenteral nutrition, and withdrawal of the catheter. According to the results, 76% of central catheters are introduced in the operating theatre: once in place, the catheter is checked by X-ray to ensure that it is in the correct position, in all cases. There were major differences in the changing of dressings. The pathway for administration of the parenteral nutrition is used for a variety of functions. Medicines are administered in "Y" with the nutrient mixture, although their stability is not known. In changing the parenteral nutrition bag and the handling of the catheter, adequate sterilization measures were not taken.(ABSTRACT TRUNCATED AT 250 WORDS)

["All in one" parenteral nutrition: is it that safe?]. / Nutrición parenteral "todo en uno": es tan segura?

The use of "all in one" admixtures is supported by an extensive number of studies and by many years of experience. However, we detected stability problems in some mixtures whose stability was previously reported. We made modifications in one of these mixtures [composed of 1.000 ml Freamine 8.5%, 100 ml 10% dextrose, 500 ml water, 500 ml Intralipid 20%, 75 ml electrolyte solution (Na 75 mEq, K 60 mEq, Ca 15 mEg, Mg 15 mEq, Cl 90 mEq, acetate 75 mEq)] in order to see how the different components affect the emulsion stability. All the admixtures were visually inspected after storage during 24 hour at room temperature. It was observed that admixtures with low glucose concentration, high electrolyte levels and high volume were less stable than admixtures containing high glucose, low electrolyte and low volume. Amino acid concentration did not increased the stability as expected. MCT/LCT emulsions were more stable than LCT emulsions. More studies are needed to explain the stability problems of these TPN solutions.

[Stability of folic acid and vitamin B12 in TPN]. / Estabilidad del ácido fólico y vitamina B12 en NPT.

The stability of folic acid (FA) in mixtures of Total Parenteral Nutrition has been and is a controversial subject, with discussion concerning the influence of factors such as temperature, light and storage time. As regards the stability of the vitamin B12, there are few studies in scientific literature. For all those reasons, we consider it necessary to make a proper study to evaluate the influence of different factors in the stability of both vitamins. The study was made on 3 liter TPN bags of the EVA type, the composition of which was as follows: AA (85g), glucosa (225g), fat (50g), Na (86mEq), K (60 mEq), Ca (15 mEq), Cl (90 mEq), P (17 mmol) acetate (149 mEq) and 10 ml of MVI-12 which contain 400 micrograms of PA and 5 micrograms of Vitamin B 12. Consideration was also given to the stability of these two vitamins in the same diet, to which were added 10 ml of a commercial preparation of oligo-elements. Six TPN bags were prepared (without oligo-elements); two of them were kept in a fridge and protected from the light, two were kept at room temperature and protected from the light and the other two at room temperature without protection from the light. Samples were taken from all the bags immediately after their preparation and after 24, 48, 72 and 96 hours. The same process was carried with other TPN bags which did contain oligo-elements. The method for determining FA and Vitamin B12 was by radioassay.(ABSTRACT TRUNCATED AT 250 WORDS)

[Epidemiology of parenteral nutrition during 5 years of follow-up by a nutrition team]. / Epidemiología de la nutrición parenteral a lo largo de cinco años de seguimiento por parte de un equipo de nutrición.

The purpose of this retrospective study is to ascertain the physiopathological characteristics of patients on parenteral nutrition (PN), the types of diet used and duration of treatment. Presentation of epidemiological results and evolution of 637 adults receiving PN after a five-year period of nutritional follow-up, conducted by a Nutrition Team (NT) in hospital. For the purpose of this study, we used the Follow-Up charts of all the patients treated with PN from 1986-1990. The results obtained lead us to affirm that most patients suffered a malignant gastrointestinal process, that the duration of the PN was reduced significantly during the five-year term, mainly using dietary protocols, and that there was a gradual increase in preparations of nutrient units subjected to controls compared to the total prepared by the Pharmacy Department.

[Cytostatic prescription errors: an analysis of causes, and proposals regarding their prevention]. / Errores de prescripción en citostáticos: análisis de sus causas y propuestas para prevenirlos.

OBJECTIVE: To collect and analyze prescription errors for parenterally-administered cytostatic drugs, to identify causes from results obtained, and to suggest feasible solutions to prevent them. METHOD: In our hospital, parenterally-administered cytotoxic drugs are prepared in the Pharmacy Department, where 100% of prescriptions are validated with the help of a software program. Prescription errors detected at validation over a 2-year period of time were recorded in a specific form to facilitate analysis. RESULTS: In all, 292 possible errors were detected and 183 were confirmed; most resulted from dosing errors, followed by incorrect treatment duration. Other errors detected included: dose or drug omitted, wrong administration route, wrong patient, and wrong medication. The following measures were suggested: improvement of the data processing system at the Pharmacy Department, implementation of an electronic prescription system, continuous updating of cytostatic therapy protocols, and inclusion of cytostatic prescription recommendations within Pharmacotherapeutic Guidelines. CONCLUSION: Most common errors included doses above or below the correct ones, with the primary cause being poor handwriting in manual prescriptions. Active recording of prescription errors is essential if an analysis of real causes in our setting is to be undertaken, as well as to making proposals and implementing definite solutions.

[Influence of antiretroviral therapy characteristics on pediatric patient adherence]. / Influencia de las características del tratamiento antirretroviral en la adherencia del paciente pediátrico.

OBJECTIVE: To analyze difficulties in achieving optimal adherence to antiretroviral therapy as perceived by pediatric patient caregivers in relation to treatment characteristics. METHODS: Design of a subjective numeric scale-based questionnaire, and its administration to caregivers of pediatric patients undergoing active antiretroviral therapy in our hospital, after verbal informed consent for interviewing. The questionnaire aimed to assess on a scale from 0 (no difficulty for adherence) to 5 (maximal difficulty) a number of treatment-related factors: a) number of drugs and dosage regimen; b) organoleptic properties of drugs; c) treatment administration; d) adverse events; and e) antiretroviral therapy effectiveness perceived by caregiver. The questionnaire was proposed to all caregivers, and was performed by a pharmacist in a private space within the pharmacy department. RESULTS: The questionnaire was administered to 28 caregivers of the 32 pediatric patients undergoing active antiretroviral therapy. The following factors were evaluated as entailing moderate difficulties: smell, deglutition, and the immediate gastrointestinal adverse effects of protease inhibitors in liquid dosage form. The only factor evaluated as entailing great difficulty was protease inhibitors flavour in the liquid dosage form. Therapy effectiveness perception was evaluated as high. CONCLUSIONS: According to the overall results from our survey, caregivers evaluated the following factors as entailing moderate to high difficulties for correct adherence: number of drugs in the antiretroviral combination, organoleptic properties (smell, taste) of protease inhibitors (PI), PI-related deglutition problems, and PI-related immediate gastrointestinal adverse events. These factors may be considered potential obstacles for adequate adherence to antiretroviral therapy in pediatric patients.

[Role of new biological therapy in psoriasis treatment]. / Papel de los nuevos tratamientos biológicos en la psoriasis.

Psoriasis is an inflammatory disease mediated by immune system T cells. The use of current systemic immunosuppressive therapies is limited by an inability to maintain disease remission safely knowledge on. Advances in recombinant DNA technology and the increase in knowledge on psoriasis immunopathology knowledge have led to the development of numerous biologic agents for the treatment of the disease. In this review the mechanisms of action for these new agents, as well as their safety profiles and efficacy data have been analyzed.

Review of hypersensitivity reactions to antineoplastic agents.

OBJECTIVE: To review the characteristics and management of hypersensitivity reactions caused by antineoplastic agents. METHOD: We conducted a search in the Pubmed and EMBASE databases for the last 10 years. RESULTS: Almost all chemotherapeutic agents have the potential to cause hypersensitivity reactions, but some groups have been associated with increased risk, such as platinum compounds, taxanes, asparaginase, monoclonal antibodies and epipodophyllotoxins. The clinical manifestations of these reactions are variable and unpredictable, including symptoms affecting the skin and the pulmonary, cardiac and gastrointestinal systems. The mechanism associated with their development is not yet fully understood. Diagnosis is based on patients' signs and symptoms and skin testing. The management of patients who suffer a hypersensitivity reaction to a chemotherapeutic agent varies with the severity of the reaction, the need to continue treatment, and the availability of alternative therapies. CONCLUSIONS: Due to a progressive increase in the use of chemotherapeutic agents an increased incidence of hypersensitivity reactions is to be expected. Desensitisation protocols are a noteworthy alternative that make it possible to re-initiate patients' therapy with the causative agent of the hypersensitivity reaction. Their use should be assessed individually, weighing risks and benefits.

[Evaluation of drug administration through enteral feeding tubes in hospitalized patients]. / Evaluación de las prácticas de administración de fármacos por sonda nasoentérica y enterostomía en pacientes hospitalizados.

OBJECTIVE: To describe the administration of drugs through nasogastric tubes by the nursing staff of a tertiary hospital and to identify the most common administration errors. METHODS: An observational study was carried out between November of 2010 and March of 2011. The study population was the nursing staff of the hospital. A questionnaire was created asking about the daily practice of drugs administration through the nasogastric tube; a score was assigned to each question. A document on correct administration techniques of drugs through the nasogastric tube was elaborated, which served for the comparison of the answers obtained. RESULTS: A total of 162 surveys were answered. Most of the staff (44.5%) had a deficient knowledge on the proper administration techniques. 69.7% of the staff stated to have grinded some time a tablet with enteric coverage, and 66.2% a tablet with modified release. A significant lower number of perceived obstructions per month was obtained in those nurses with higher degree of knowledge, in those consulting the Pharmacy Department when they had doubts, and in those never having grinded a tablet with enteric coverage of modified release. CONCLUSIONS: It is observed that the knowledge on proper administration of drugs through the nasogastric tube by the nursing staff is deficient; therefore, it would be convenient to carry out specific training courses as well as a closer collaboration between the Pharmacy department and the Nursing units.

[Home parenteral nutrition in infants and children in a tertiary level hospital between 1993 and 2009]. / Nutrición parenteral domiciliaria en niños en un hospital terciario entre los años 1993 y 2009.

UNLABELLED: Home parenteral nutrition (HPN) has a key role in the management of permanent or transient intestinal failure in the pediatric patient. Although its use is not without complications. We review our experience since the beginning of the program in 1993. PATIENTS AND METHODS: Longitudinal and retrospective study of the clinical records from 25 infants and children (11 boys, 14 girls) who received HPN in this period. If a patient received HPN in periods separated more than 3 months we consider a different episode. In this way, 32 episodes were described. Quantitative data are presented as mean or median and qualitative as frequency. Complications are presented as complication rate per 1,000 days of HPN. RESULTS: 16 patients started HPN younger than 1 year. Total length of HPN was 9,986 days, median 174 days (range 7 to 2,444 days). Main indication was short bowel syndrome (n = 6); motility disorders (n = 6); chronic diarrhea (n = 5), malnutrition (n = 3) and other causes (n = 5). 47 catheters were used; mean length 212.5 days, median 120 days (range: 7 to 930). Most of central venous catheters were tunnelled catheters (n = 42); subcutaneous ports (n=3) and in two cases periferically inserted central catheters (PICCS). Complication rate per 1,000 days of HPN was: 3.4 for catheter-related infections, 0.1 for obstruction; 0.9 for leakage, and 0.1 for accidental removal. Most common microorganisms were Staphylococcus coagulase negative (47%), Gram negative bacteria (21%), Staphylococcus aureus (15%), fungi (9%) and others in 9%. Parenteral nutrition-associated liver disease was present in 4 patients. 21 patients were weaned off HPN, 3 patients deceased because of underlying disease, 2 patients underwent intestinal transplantation, while 5 patients continue in the program. CONCLUSIONS: Every year two new patients enter in the program. 65% of patients were weaned off HPN. Infectious complications were the most frequent (rate 3.4 infections per 1,000 days of HPN). Mean length of HPN was 174 days, and 120 days for catheters.

[Evolution of paediatric parenteral nutrition over the last 15 years in a tertiary hospital in Madrid (Spain)]. / Variación en el uso de nutrición parenteral en un hospital infantil en Madrid (España) a lo largo de 15 años.

OBJECTIVE: To analyze the use of paediatric parenteral nutrition (PN) in a tertiary level hospital in Spain (1994-2008). MATERIALS AND METHODS: The charts from infants and children receiving NP in 2008 were reviewed. Data were compared with those in 1994 and 2002. RESULTS: 120 patients received PN, 78 and 71 corresponding to 1.6%, 1.3% and 1.0% of total admissions in 2008, 2002 and 1994 respectively. When composition of PN was compared in the first day we found significant differences in energy and lipids; but not in volume, carbohydrate, or amino acid composition. Gastrointestinal surgery was the most common indication. Mean length was 11.0 ± 9.8 days (2008) to 15.2 ± 14.8 (1994) (p < 0.05). Complications were present in 24.8 patients (2008), 10.8% (2002) and 16.9 (1994). CONCLUSIONS: PN use increased along the study period, although mean length decreased. There were more complications in 2008 than in previous years.
