[Problems encountered by hospital pharmacists with information systems: Analysis of exchanges within social networks]. / Problèmes rencontrés par les pharmaciens des établissements de santé avec les systèmes d'information hospitaliers : analyse des échanges opérés au sein de réseaux sociaux.

OBJECTIVE: The development of information systems in French hospitals is mandatory. The aim of this work was to analyze the content of exchanges carried out within social networks, dealing with problems encountered with hospital pharmacies information systems. METHODS: Messages exchanged via the mailing list of the Association pour le Digital et l'Information en Pharmacie and abstracts of communications presented at hospital pharmacists trade union congresses were analyzed. Those referring to information systems used in hospital pharmacies were selected. RESULTS: From March 2015 to June 2016, 122 e-mails sent by 80 pharmacists concerned information systems. From 2002 to 2016, 45 abstracts dealt with this topic. Problems most often addressed in these 167 documents were "parameterization and/or functionalities" (n=116), interfaces and complexity of the hospital information systems (n=52), relationship with health information technologies vendors and poor reactivity (n=32), additional workload (n=32), ergonomics (n=30), insufficient user training (n=22). These problems are interdependent, lead to errors and in order to mitigate their consequences, they compel pharmacy professionals to divert a significant amount of working hours to the detriment of pharmaceutical care and dispensing and preparing drugs. CONCLUSION: Hospital pharmacists are faced with many problems of insecurity and inefficiency generated by information systems. Researches are warranted to determine their cost, specify their deleterious effects on care and identify the safest information systems.

Electromagnetic evidence that SSS17a is the result of a binary neutron star merger.

Eleven hours after the detection of gravitational wave source GW170817 by the Laser Interferometer Gravitational-Wave Observatory and Virgo Interferometers, an associated optical transient, SSS17a, was identified in the galaxy NGC 4993. Although the gravitational wave data indicate that GW170817 is consistent with the merger of two compact objects, the electromagnetic observations provide independent constraints on the nature of that system. We synthesize the optical to near-infrared photometry and spectroscopy of SSS17a collected by the One-Meter Two-Hemisphere collaboration, finding that SSS17a is unlike other known transients. The source is best described by theoretical models of a kilonova consisting of radioactive elements produced by rapid neutron capture (the r-process). We conclude that SSS17a was the result of a binary neutron star merger, reinforcing the gravitational wave result.

Early spectra of the gravitational wave source GW170817: Evolution of a neutron star merger.

On 17 August 2017, Swope Supernova Survey 2017a (SSS17a) was discovered as the optical counterpart of the binary neutron star gravitational wave event GW170817. We report time-series spectroscopy of SSS17a from 11.75 hours until 8.5 days after the merger. Over the first hour of observations, the ejecta rapidly expanded and cooled. Applying blackbody fits to the spectra, we measured the photosphere cooling from [Formula: see text] to [Formula: see text] kelvin, and determined a photospheric velocity of roughly 30% of the speed of light. The spectra of SSS17a began displaying broad features after 1.46 days and evolved qualitatively over each subsequent day, with distinct blue (early-time) and red (late-time) components. The late-time component is consistent with theoretical models of r-process-enriched neutron star ejecta, whereas the blue component requires high-velocity, lanthanide-free material.

Light curves of the neutron star merger GW170817/SSS17a: Implications for r-process nucleosynthesis.

On 17 August 2017, gravitational waves (GWs) were detected from a binary neutron star merger, GW170817, along with a coincident short gamma-ray burst, GRB 170817A. An optical transient source, Swope Supernova Survey 17a (SSS17a), was subsequently identified as the counterpart of this event. We present ultraviolet, optical, and infrared light curves of SSS17a extending from 10.9 hours to 18 days postmerger. We constrain the radioactively powered transient resulting from the ejection of neutron-rich material. The fast rise of the light curves, subsequent decay, and rapid color evolution are consistent with multiple ejecta components of differing lanthanide abundance. The late-time light curve indicates that SSS17a produced at least ~0.05 solar masses of heavy elements, demonstrating that neutron star mergers play a role in rapid neutron capture (r-process) nucleosynthesis in the universe.

Quality of prescribing in community-dwelling elderly patients in France: an observational study in community pharmacies.

Background In order to ensure safer prescriptions in the elderly, lists of potentially inappropriate medications (PIMs) and guidelines have been introduced. Whereas the effectiveness of these measures has been well studied in hospitals, data are sparse for the community-dwelling patients. Objective To assess the quality of prescriptions among community-dwelling elderly patients, and potential associations between prescription patterns, patient characteristics and medication adherence. Setting Community pharmacies in France. Method We conducted a prospective observational study between January and June 2013. Patients aged 75 and over coming to the community pharmacy with a prescription from a general practitioner were invited to participate to the study. The compliance of the prescription was assessed with regards to Beers Criteria and French Health Authority guidelines (FHA) for prescription in the elderly, the degree of adherence was assessed with the Girerd score. Main outcome measure Percentage of prescriptions compliant with Beers Criteria and FHA guidelines. Results Among the 1206 prescriptions analysed, 67.49% (n = 814) contained a PIM. Only 12.77% (n = 154) complied with mandatory requirements of the FHA. Prescriptions were ordered by therapeutic field in 51.24% (n = 618) of cases. Dosing regimen was incomplete in 57.21% (n = 690) of prescriptions. Only 29.19% (n = 352) of patients reported no difficulty with regard to adherence (Girerd score = 0). The use of International Non-proprietary Name was associated with an increased risk of nonadherence (adjusted OR = 1.59 [95% CI = 1.13-2.23] and 1.68 [95% CI = 1.12-2.49] respectively). Patient satisfaction with formulation was associated with a lower risk of non-adherence (adjusted OR = 0.63 [95% CI = 0.45-0.90]). Conclusion A substantial proportion of patients are exposed to PIMs and prescriptions that do not comply with the FHA Guidelines. This issue, as well as identified risk factors for non-adherence, should be taken into consideration by general practitioners and community pharmacists when prescribing/dispensing medications to the elderly.

[Which useful Apps are installed on my smartphone as a clinical pharmacist?] / Quelles Apps utiles sur mon smartphone de pharmacien clinicien ?

Since the advent of PDAs (Personal Digital Assistants), smartphones and Apps have been widely adopted by medical professionals. This craze has increased since 2007 and the first generation iPhone. In this context, 3 questions emerged for the pharmacist that we studied in this review: (1) What Apps are available for practice and how to find them? (2) What is useful for practice? (3) What precautions should be taken?

[Distal radius fractures: Which classification is the right one?] / Fractures de l'extrémité distale du radius : quelle classification choisir ?

None of the classification systems for distal radius fractures is ideal. However a validated system to analyze these fractures is available that is based on the "metaphysis, epiphysis, ulna" (MEU) classification and the "patient, accident, fracture" (PAF) system. It makes it possible to understand the injury and select the best treatment.

Prospective multicentre study of the clinical and functional outcomes following quadriceps tendon repair with suture anchors.

INTRODUCTION: Quadriceps tendon avulsions are typically treated by reattaching the tendon through bone tunnels, with or without tendon or hardware augmentation. The operated knee joint can be moved right away; however, tendon grafting or tension banding will be required to protect the repair, and the hardware must be removed later on. The goal of this study was to evaluate the clinical and functional outcomes when suture anchors are used to reattached torn quadriceps tendon, and also to assess tendon healing using MRI. MATERIALS AND METHODS: Thirteen consecutive patients with avulsed quadriceps tendons were operated and then followed prospectively. The surgical technique consisted of tendon reattachment using at least three anchors, in addition to intratendinous weaving of the sutures. Weight bearing was allowed while using a splint. Rehabilitation was initiated immediately after surgery according to a set protocol. RESULTS: Eleven patients were followed for a mean of 14.7 months. Two retears occurred in patients who did not wear the splint. Eighty-two per cent of patients were satisfied or very satisfied with the outcome. The mean knee flexion was 124.5°. All patients were able to return to their pre-injury activity levels. The mean time for clinical and functional recovery was 3 months. MRI performed 6 months after the surgical repair revealed good tendon healing. DISCUSSION: This was the first prospective study performed on quadriceps avulsion patients undergoing suture anchor repair. Prior clinical case reports have shown that this method leads to predictable clinical and functional results. Our results were comparable to those in published cases. CONCLUSION: The procedure is simpler when only suture anchors are used. Tendon healing was observed on MRI in all cases. This simple, reproducible technique is free of the drawbacks associated with the typical repair augmentation.

Interfering with multimerization of netrin-1 receptors triggers tumor cell death.

Netrin-1 was recently proposed to control tumorigenesis by inhibiting apoptosis induced by the dependence receptors DCC (Deleted in colorectal cancer) and UNC5H. Although the loss of these dependence receptors' expression has been described as a selective advantage for tumor growth and progression in numerous cancers, recent observations have shown that some tumors may use an alternative strategy to block dependence receptor-induced programmed cell death: the autocrine expression of netrin-1. This alternative strategy has been observed in a large fraction of aggressive breast cancers, neuroblastoma, pancreatic adenocarcinoma, and lung cancer. This observation is of potential interest regarding future targeted therapy, as in such cases interfering with the ability of netrin-1 to inhibit DCC or UNC5H-induced cell death is associated with apoptosis of netrin-1-expressing tumor cells in vitro, and with inhibition of tumor growth or metastasis in different animal tumor models. The understanding of the mechanism by which netrin-1 inhibits cell death is therefore of interest. Here, we show that netrin-1 triggers the multimerization of both DCC and UNC5H2 receptors, and that multimerization of the intracellular domain of DCC and UNC5H2 is the critical step to inhibit the proapoptotic effects of both of these receptors. Taking advantage of this property, we utilized a recombinant specific domain of DCC that (i) interacts with netrin-1 and (ii) inhibits netrin-1-induced multimerization, to trigger apoptosis in netrin-dependent tumor cells.

[Surgical antimicrobial prophylaxis: compliance to guidelines and impact of targeted information program]. / Antibioprophylaxie chirurgicale: adéquation aux recommandations et impact d'une action d'information ciblée.

OBJECTIVES: Surgical antimicrobial prophylaxis is used to decrease postoperative wound infection. We assessed the compliance to surgical antimicrobial prophylaxis guidelines in our hospital and the impact of an information program. PATIENTS AND METHODS: Observational study of clean or clean contamined surgery, during two 3-week periods, separated by a targeted information period. The following data were collected prospectively: prophylaxis indication, antimicrobial agent, timing, dose, route and duration of prophylaxis. Chi square test was used for analysis or Fischer test when available. RESULTS: Four hundred seventy-seven patients were enrolled - 270 and 207 for each period respectively. For both periods only 49% of prophylaxis was appropriated. When prophylaxis should be administered - 15 and 13% of patients for each period - it was antibioprophylaxy was strictly adequate with recommandations. The most common error was administration timing. Only the choice of antimicrobial agent was optimized after information period. DISCUSSION: These results are consistent with previous studies. Information program alone have no effect on the good use of antimicrobial for surgical prophylaxis. Only a policy associating organization, restriction and education could improve practices.

[Drug administration to paediatric inpatient]. / L'administration des médicaments à l'enfant hospitalisé.

OBJECTIVE: Available commercial drugs in France are often unsuitable for children. The aim of this study was, for every medicinal form orally or parenterally administered, to identify and to quantify difficulties met by the nurses administering drugs to paediatric inpatients and to propose solutions to main identified problems. MATERIAL AND METHOD: The study was realized in 14 hospitals by direct observation. The observer, provided with a questionnaire, followed during a time slot of at least 2 h for one or several nurses and raised all the oral or injectable administrations. RESULTS: One thousand and nine hundred forty-six observations were performed. The children were 12.6 +/- 17 months old, and weighed 8.5 +/- 9.4 kg. Injectable drugs: half of the observations showed a posology and a mode of dilution not corresponding to the summary of product characteristics. Eight percent of orally administered drugs were injectable drugs. In 35.5% of cases, administered amount was lower than the quarter of the present quantity in the therapeutic unity. The rest of the therapeutic unity was thrown (77.2% of cases). Liquid oral forms: liquid oral forms were ready for use regarding 83.8% of cases. The medicine was readministered to the same patient (23.5%), and/or administered to other patients (80.0%). Capsules: 66.9% of the administered capsules were prepared by the hospital pharmacies. The pharmacies organized with an unit dose drug dispensing system produced significantly more preparations than those working by global distribution (P < 0.0001). In 58.4% of cases, the administered capsule was an off-label drug. Tablets: 46% of drug administration concerned a tablet without pediatric indication. 46.7% of tablets were cut, 74% were crushed. Bags: in 35.2% of observations, the bag was not administered in its entirety. CONCLUSION: Our study confirms the unsuitability of drugs to paediatric inpatients, the necessity of recommendations of good practices in the administration of drugs to paediatric inpatients, and proposes corrective actions.

[Brachial plexus anesthesia via an axillary route for emergency surgery: comparison of three approach methods]. / Anesthésie du plexus brachial par voie axillaire pour chirurgie urgente: comparaison de trois méthodes d'approche.

OBJECTIVES: To compare three techniques of brachial plexus blockade for emergency surgery of the upper limb. STUDY DESIGN: Prospective, randomised study. PATIENTS: One hundred eleven patients admitted to an emergency surgical service, randomly assigned to three groups. METHODS: The patients were given 2% lidocaine with epinephrine 20 mL and 0.5% bupivacaine 20 mL. The three groups were as follows: brachial plexus block using a peripheral nerve stimulator (group St, n = 38); transarterial brachial plexus blockade with injection of 2/3 of the anaesthetic in back of and 1/3 in front of the artery (group TAP, n = 36); transarterial brachial plexus blockade with one single injection in back of the artery (group TP, n = 37). The success rate, time required to perform the technique, latency of analgesia, quality of motor blockade, and adverse effects were compared between the three groups. Analysis of variance was used to compare quantitative data and chi 2 test were used for qualitative data. RESULTS: Rates of success varied between 65 and 75%. Success rates, latency of analgesia and quality of motor blockade were not significantly different between groups. Time to perform the technique was longer when using a nerve stimulator. CONCLUSION: As these three techniques for brachial plexus block in emergency surgery are comparable, no one can be recommended instead of the others.

[Benzodiazepine withdrawal presenting as pseudo-surgical abdominal pain]. / Sevrage en benzodiazépines révélé par un syndrome douloureux abdominal pseudochirurgical.

A 39-year-old patient was admitted to the emergency department for acute abdominal pain. Physical examination showed a peritoneal syndrome. However, CT-scan, Doppler and blood analysis were unremarkable. As the patient had a history of auto-medication with benzodiazepines at high doses, a withdrawal syndrome was considered. An intravenous administration of 3 mg of midazolam determined the relief of all symptoms in a few minutes.
