Project description:The traditional requirement for clean rooms and specialized skills has inhibited many biologists from pursuing new microfluidic innovations. Makerspaces provide a growing alternative to clean rooms: they provide low-cost access to fabrication equipment such as laser cutters, plotter cutters, and 3D printers; use commercially available materials; and attract a diverse community of product designers. This Opinion discusses the materials, tools, and building methodologies particularly suited for developing novel microfluidic devices in these spaces, with insight into biological applications and leveraging the maker community. The lower barrier to access of makerspaces ameliorates the otherwise poor accessibility and scalability of microfluidic prototyping.

Project description:Although the cultivable and noncultivable microbial diversity of spacecraft assembly clean rooms has been previously documented using conventional and state-of-the-art molecular techniques, the occurrence of obligate anaerobes within these clean rooms is still uncertain. Therefore, anaerobic bacterial communities of three clean-room facilities were analyzed during assembly of the Mars Science Laboratory rover. Anaerobic bacteria were cultured on several media, and DNA was extracted from suitable anaerobic enrichments and examined with conventional 16S rRNA gene clone library, as well as high-density phylogenetic 16S rRNA gene microarray (PhyloChip) technologies. The culture-dependent analyses predominantly showed the presence of clostridial and propionibacterial strains. The 16S rRNA gene sequences retrieved from clone libraries revealed distinct microbial populations associated with each clean-room facility, clustered exclusively within gram-positive organisms. PhyloChip analysis detected a greater microbial diversity, spanning many phyla of bacteria, and provided a deeper insight into the microbial community structure of the clean-room facilities. This study presents an integrated approach for assessing the anaerobic microbial population within clean-room facilities, using both molecular and cultivation-based analyses. The results reveal that highly diverse anaerobic bacterial populations persist in the clean rooms even after the imposition of rigorous maintenance programs and will pose a challenge to planetary protection implementation activities.

Project description:AimsTo screen for the predominant bacteria strains distributed in clean rooms and to analyze their phylogenetic relationships.Methods and resultsThe bacteria distributed in air, surfaces and personnel in clean rooms were routinely monitored using agar plates. Five isolates frequently isolated from the clean rooms of an aseptic pharmaceutical production workshop were selected based on their colony and cell morphology characteristics. Their physiological and biochemical properties, as well as partial 16S rDNA sequences, were analyzed. Results showed that all the five isolates belong to Gram positive bacteria, of which three were Staphylococcus, one Microbacterium and one Bacillus species. Sensitivity tests for these bacteria isolates to 3 disinfectants showed that isolate F03 was obtuse, and had low susceptivity to UV irradiation, while isolates F02, F01 and F04 were not sensitive to phenol treatment. Isolates F04, F01 and F05 were resistant to chlorhexidine gluconate.ConclusionBacteria widely distributed in clean rooms are mainly a group of Gram positive strains, showing high resistance to selected disinfectants.Significance and impact of the studyClean rooms are essential in aseptic pharmaceutical and food production. Screening bacteria isolates and identifying them is part of good manufacturing practices, and will aid in finding a more effective disinfection method.

Project description:A census of clean room surface-associated bacterial populations was derived from the results of both the cloning and sequencing of 16S rRNA genes and DNA microarray (PhyloChip) analyses. Samples from the Lockheed Martin Aeronautics Multiple Testing Facility (LMA-MTF), the Kennedy Space Center Payload Hazard and Servicing Facility (KSC-PHSF), and the Jet Propulsion Laboratory Spacecraft Assembly Facility (JPL-SAF) clean rooms were collected during the various assembly phases of the Phoenix and Mars Science Laboratory (MSL) spacecraft. Clone library-derived analyses detected a larger bacterial diversity prior to the arrival of spacecraft hardware in these clean room facilities. PhyloChip results were in agreement with this trend but also unveiled the presence of anywhere from 9- to 70-fold more bacterial taxa than cloning approaches. Among the facilities sampled, the JPL-SAF (MSL mission) housed a significantly less diverse bacterial population than either the LMA-MTF or KSC-PHSF (Phoenix mission). Bacterial taxa known to thrive in arid conditions were frequently detected in MSL-associated JPL-SAF samples, whereas proteobacterial lineages dominated Phoenix-associated KSC-PHSF samples. Comprehensive bacterial censuses, such as that reported here, will help space-faring nations preemptively identify contaminant biomatter that may compromise extraterrestrial life detection experiments. The robust nature and high sensitivity of DNA microarray technologies should prove beneficial to a wide range of scientific, electronic, homeland security, medical, and pharmaceutical applications and to any other ventures with a vested interest in monitoring and controlling contamination in exceptionally clean environments.

Project description:ObjectivesThis study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.MethodCited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford's Law of Scattering was applied to both sets to determine the most frequently cited journals.ResultsThree-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.ConclusionHospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field.

Project description:Previous studies demonstrate an exchange of bacteria between hospital room surfaces and patients, and a reduction in survival of microorganisms in dust inside buildings from sunlight exposure. While the transmission of microorganisms between humans and their local environment is a continuous exchange which generally does not raise cause for alarm, in a hospital setting with immunocompromised patients, these building-source microbial reservoirs may pose a risk. Window glass is often neglected during hospital disinfection protocols, and the microbial communities found there have not previously been examined. This pilot study examined whether living bacterial communities, and specifically the pathogens Methicillin-resistant Staphylococcus aureus (MRSA) and Clostridioides difficile (C. difficile), were present on window components of exterior-facing windows inside patient rooms, and whether relative light exposure (direct or indirect) was associated with changes in bacterial communities on those hospital surfaces. Environmental samples were collected from 30 patient rooms in a single ward at Oregon Health & Science University (OHSU) in Portland, Oregon, USA. Sampling locations within each room included the window glass surface, both sides of the window curtain, two surfaces of the window frame, and the air return grille. Viable bacterial abundances were quantified using qPCR, and community composition was assessed using Illumina MiSeq sequencing of the 16S rRNA gene V3/V4 region. Viable bacteria occupied all sampled locations, but was not associated with a specific hospital surface or relative sunlight exposure. Bacterial communities were similar between window glass and the rest of the room, but had significantly lower Shannon Diversity, theorized to be related to low nutrient density and resistance to bacterial attachment of glass compared to other surface materials. Rooms with windows that were facing west demonstrated a higher abundance of viable bacteria than those facing other directions, potentially because at the time of sampling (morning) west-facing rooms had not yet been exposed to sunlight that day. Viable C. difficile was not detected and viable MRSA was detected at very low abundance. Bacterial abundance was negatively correlated with distance from the central staff area containing the break room and nursing station. In the present study, it can be assumed that there is more human traffic in the center of the ward, and is likely responsible for the observed gradient of total abundance in rooms along the ward, as healthcare staff both deposit more bacteria during activities and affect microbial transit indoors. Overall, hospital window components possess similar microbial communities to other previously identified room locations known to act as reservoirs for microbial agents of hospital-associated infections.

Project description:BackgroundThe Canadian Society of Hospital Pharmacists promotes the recruitment of residency-trained pharmacists for work in hospitals and related health care settings. However, Quebec hospitals are still hiring non-residency trained pharmacists, in part because of a severe shortage of hospital pharmacists. To date, no studies have examined the factors influencing the career choices of fourth-year pharmacy students in Canada.ObjectivesTo identify motivating factors and barriers influencing students' decision to pursue a hospital pharmacy residency.MethodsAll 186 fourth-year students in the Faculty of Pharmacy, Université de Montréal, were invited by e-mail to participate in a validated and institutionally approved survey that was available online between March and May 2014.ResultsOf the 138 respondents who returned a completed survey (74% response rate), 36 (26%) planned to apply for a hospital pharmacy residency. Those planning to apply for a residency were older (p = 0.037) and had more hospital work experience (36% versus 3%, p < 0.001) than those not planning to apply. The most important motivators for pursuing a residency were potential gains in knowledge (reported by 88% of respondents, whether or not they were planning to pursue a residency), experience (80%), and self-confidence (62%). The most frequently reported barriers were recognition that a hospital pharmacy residency is a highly demanding program (65%), having work available upon graduation from the undergraduate program (43%), and financial obligations (34%). Hospital experiential rotations influenced, either positively or negatively, 23 (72%) of the 32 students who changed their decision to pursue or not pursue residency training over the course of their studies.ConclusionsThe potential gain in knowledge and experience acquired through residency, the fact that it is considered a highly demanding program, and having work available upon graduation from undergraduate studies were the most influential factors in fourth-year pharmacy students' decision of whether to pursue a hospital pharmacy residency.

Project description:Objectives: For decades, the role of hospital pharmacists has been instrumental in elevating pharmacy practice worldwide. Recently, the Hospital Pharmacy Section of the International Pharmaceutical Federation (FIP), the European Association of Hospital Pharmacists (EAHP), and the American Society of Health-System Pharmacists (ASHP) updated their statements about the future role and responsibilities of the pharmacy executive in hospitals and health systems. A series of surveys were conducted around the globe to better understand the current state of hospital pharmacy practice. The purpose of these surveys was to identify challenges in hospital pharmacy practice and to develop improvement strategies. The objective of this national survey is to evaluate hospital pharmacy practice in Lebanon. Methods: A cross-sectional observational study was performed among pharmacists working in hospital settings in Lebanon, from January through June 2016. Based on a literature review, a questionnaire to elicit Lebanese hospital pharmacists' practice was developed. Results: The results showed a nonsignificant difference between university teaching and nonuniversity teaching hospitals in the processes of drug procurement, preparation, dispensing, and drug administration. However, statistically significant differences were observed between university teaching and nonuniversity teaching hospitals with respect to having clinical pharmacists (P < .001) and highly qualified personnel (P < .005). Pharmacy services in teaching hospitals seemed to be more advanced cooperating with affiliated medical schools. Furthermore, teaching hospitals were more likely to have pharmacists providing information about the safety of the medications used (P = .029). Although not statistically significant, there was a higher trend toward having a designated champion for medication safety (P = .052). Conclusion: The results of our survey showed that teaching hospitals were more compliant with the International Statements of Hospital Pharmacy Practice compared with nonteaching hospitals. There is room for improvement especially if the application of the accreditation standards for safe hospital pharmacy practice becomes mandatory for all hospitals, which is expected to standardize pharmacy practice and secure both medication and patient safety.
