Multiclonal human origin and global expansion of an endemic bacterial pathogen of livestock.

Most new pathogens of humans and animals arise via switching events from distinct host species. However, our understanding of the evolutionary and ecological drivers of successful host adaptation, expansion, and dissemination are limited. Staphylococcus aureus is a major bacterial pathogen of humans and a leading cause of mastitis in dairy cows worldwide. Here we trace the evolutionary history of bovine S. aureus using a global dataset of 10,254 S. aureus genomes including 1,896 bovine isolates from 32 countries in 6 continents. We identified 7 major contemporary endemic clones of S. aureus causing bovine mastitis around the world and traced them back to 4 independent host-jump events from humans that occurred up to 2,500 y ago. Individual clones emerged and underwent clonal expansion from the mid-19th to late 20th century coinciding with the commercialization and industrialization of dairy farming, and older lineages have become globally distributed via established cattle trade links. Importantly, we identified lineage-dependent differences in the frequency of host transmission events between humans and cows in both directions revealing high risk clones threatening veterinary and human health. Finally, pangenome network analysis revealed that some bovine S. aureus lineages contained distinct sets of bovine-associated genes, consistent with multiple trajectories to host adaptation via gene acquisition. Taken together, we have dissected the evolutionary history of a major endemic pathogen of livestock providing a comprehensive temporal, geographic, and gene-level perspective of its remarkable success.

Augmented surveillance of antimicrobial resistance with high-throughput robotics detects transnational flow of fluoroquinolone-resistant Escherichia coli strain into poultry.

BACKGROUND: Food animal AMR surveillance programs assess only small numbers of Escherichia coli (from 100 to 600 per animal class) nationally each year, severely limiting the evaluation of public health risk(s). Here we demonstrate an affordable approach for early detection of emerging resistance on a broad scale that can also accurately characterize spatial and temporal changes in resistance. METHODS: Caecal samples (n = 295) obtained from 10 meat poultry were screened using high-throughput robotics. Initial screening via agar dilution (5310 plates) quantified AMR carriage (cfu/g) for each sample. Ciprofloxacin-resistant isolates (n = 91) proceeded to downstream broth microdilution susceptibility testing. A subset of 28 ciprofloxacin-resistant isolates underwent WGS and phylogenetic analysis. RESULTS: Intra- and inter-flock carriage of resistance varied with drug class. Ampicillin and tetracycline resistance was ubiquitous to most birds in all flocks with an average carriage rate of 5.8 log10 cfu/g. Gentamicin and ciprofloxacin-resistant E. coli colonized fewer birds, and had an average carriage rate of 1.2 log10 cfu/g and 1.0 log10 cfu/g of faeces, respectively. Resistance to extended-spectrum cephalosporins was absent. ST354 was the dominant ST among the WGS isolates, but they demonstrated markedly lower resistance gene carriage than their international counterparts. CONCLUSIONS: These data amply demonstrate the ineffectiveness of commonly relied-on approaches to AMR surveillance for achieving early detection of emergence, or for measuring spatial and temporal resistance trends. Genetic analysis suggested there has been transnational flow of a ciprofloxacin-resistant strain into Australian poultry flocks, explaining their detection in a nation that prohibits fluoroquinolone use in poultry.

Diversity detected in commensals at host and farm level reveals implications for national antimicrobial resistance surveillance programmes.

BACKGROUND: A key component to control of antimicrobial resistance (AMR) is the surveillance of food animals. Currently, national programmes test only limited isolates per animal species per year, an approach tacitly assuming that heterogeneity of AMR across animal populations is negligible. If the latter assumption is incorrect then the risk to humans from AMR in the food chain is underestimated. OBJECTIVES: To demonstrate the extent of phenotypic and genetic heterogeneity of Escherichia coli in swine to assess the need for improved protocols for AMR surveillance in food animals. METHODS: Eight E. coli isolates were obtained from each of 10 pigs on each of 10 farms. For these 800 isolates, AMR profiles (MIC estimates for six drugs) and PCR-based fingerprinting analysis were performed and used to select a subset (n = 151) for WGS. RESULTS: Heterogeneity in the phenotypic AMR traits of E. coli was observed in 89% of pigs, with 58% of pigs harbouring three or more distinct phenotypes. Similarly, 94% of pigs harboured two or more distinct PCR-fingerprinting profiles. Farm-level heterogeneity was detected, with ciprofloxacin resistance detected in only 60% of pigs from a single farm. Furthermore, 58 STs were identified, with the dominant STs being ST10, ST101, ST542 and ST641. CONCLUSIONS: Phenotypic and genotypic heterogeneity of AMR traits in bacteria from animal populations are real phenomena posing a barrier to correct interpretation of data from AMR surveillance. Evolution towards a more in-depth sampling model is needed to account for heterogeneity and increase the reliability of inferences.

The changing molecular epidemiology of Enterococcus faecium harbouring the van operon at a teaching hospital in Western Australia: A fifteen-year retrospective study.

INTRODUCTION: Enterococcus faecium is an opportunistic pathogen that has become one of the leading causes of hospital acquired infection that are resistant to multiple critically important antimicrobials. AIM: The objective of the study was to describe the molecular characteristics and relationship between major strains of E. faecium harbouring the van operon and to determine if the strains had increasing virulence and antimicrobial resistance determinants over time. METHODS: E. faecium harbouring the van operon detected using PCR from surveillance rectal swabs of patients that were admitted to high-risk units at a Perth teaching hospital from 2001 to 2015 were retrospectively analysed using a whole genome sequencing and bioinformatics approach. RESULTS: ST18, ST78, ST80, ST173, ST203 and ST555 were identified as the major STs accounting for 93.7% of E. faecium isolates. Except for ST173, major STs identified at Royal Perth Hospital (RPH) have been reported across Australia and internationally. Isolates from each ST formed independently branched phylogenetic clusters with each harbouring unique virulence and antimicrobial resistance profiles. Depending on the ST, different genes conferring resistance to similar antimicrobial classes were identified. Except for ST80 which harboured the vanA type operon, all major strains harboured the vanB operon conferring only vancomycin resistance. CONCLUSION: Major strains of E. faecium isolated over 15-years showed unique virulome and resistome profiles with no indication of increasing virulence or antimicrobial resistance determinants. Strains were distantly related and the acquisition of different genes encoding similar antimicrobial resistances suggest the independent evolution of each strain. DATA SUMMARY: The whole genome sequences of all isolates from this study are accessible from the NCBI-SRA database under project number PRJNA575940 and PRJNA524213. Published reference sequence Aus0004 was obtained from NCBI-SRA under project number PRJNA86649 DOI:10.1128/JB.00259-12.

In Vitro Demonstration of Targeted Phage Therapy and Competitive Exclusion as a Novel Strategy for Decolonization of Extended-Spectrum-Cephalosporin-Resistant Escherichia coli.

Extended-spectrum cephalosporin-resistant (ESC-R) Escherichia coli have disseminated in food-producing animals globally, attributed to horizontal transmission of blaCTX-M variants, as seen in the InCI1-blaCTX-M-1 plasmid. This ease of transmission, coupled with its demonstrated long-term persistence, presents a significant One Health antimicrobial resistance (AMR) risk. Bacteriophage (phage) therapy is a potential strategy in eliminating ESC-R E. coli in food-producing animals; however, it is hindered by the development of phage-resistant bacteria and phage biosafety concerns. Another alternative to antimicrobials is probiotics, with this study demonstrating that AMR-free commensal E. coli, termed competitive exclusion clones (CECs), can be used to competitively exclude ESC-R E. coli. This study isolated and characterized phages that lysed E. coli clones harboring the InCI1-blaCTX-M-1 plasmid, before investigation of the effect and synergy of phage therapy and competitive exclusion as a novel strategy for decolonizing ESC-resistant E. coli. In vitro testing demonstrated superiority in the combined therapy, reducing and possibly eliminating ESC-R E. coli through phage-mediated lysis coupled with simultaneous prevention of regrowth of phage-resistant mutants due to competitive exclusion with the CEC. Further investigation into this combined therapy in vivo is warranted, with on-farm application possibly reducing ESC-R prevalence, while constricting newly emergent ESC-R E. coli outbreaks prior to their dissemination throughout food-producing animals or humans. IMPORTANCE The emergence and global dissemination of resistance toward critically important antimicrobials, including extended-spectrum cephalosporins in the livestock sector, deepens the One Health threat of antimicrobial resistance. This resistance has the potential to disseminate to humans, directly or indirectly, nullifying these last lines of defense in life-threatening human infections. This study explores a novel strategy, the coadministration of bacteriophages (phages) and a competitive exclusion clone (antimicrobial-susceptible commensal E. coli), to revert an antimicrobial-resistant population to a susceptible population. While phage therapy is vulnerable to the emergence of phage-resistant bacteria, no phage-resistant bacteria emerged when a competitive exclusion clone was used in combination with the phage. Novel strategies that reduce the prevalence and slow the dissemination of extended-spectrum cephalosporin-resistant E. coli in food-producing animals have the potential to extend the time frame in which antimicrobials remain available for effective use in animal and human health.

Robotic Antimicrobial Susceptibility Platform (RASP): a next-generation approach to One Health surveillance of antimicrobial resistance.

BACKGROUND: Surveillance of antimicrobial resistance (AMR) is critical to reducing its wide-reaching impact. Its reliance on sample size invites solutions to longstanding constraints regarding scalability. A robotic platform (RASP) was developed for high-throughput AMR surveillance in accordance with internationally recognized standards (CLSI and ISO 20776-1:2019) and validated through a series of experiments. METHODS: Experiment A compared RASP's ability to achieve consistent MICs with that of a human technician across eight replicates for four Escherichia coli isolates. Experiment B assessed RASP's agreement with human-performed MICs across 91 E. coli isolates with a diverse range of AMR profiles. Additionally, to demonstrate its real-world applicability, the RASP workflow was then applied to five faecal samples where a minimum of 47 E. coli per animal (239 total) were evaluated using an AMR indexing framework. RESULTS: For each drug-rater-isolate combination in Experiment A, there was a clear consensus of the MIC and deviation from the consensus remained within one doubling dilution (the exception being gentamicin at two dilutions). Experiment B revealed a concordance correlation coefficient of 0.9670 (95% CI: 0.9670-0.9670) between the robot- and human-performed MICs. RASP's application to the five faecal samples highlighted the intra-animal diversity of gut commensal E. coli, identifying between five and nine unique isolate AMR phenotypes per sample. CONCLUSIONS: While adhering to internationally accepted guidelines, RASP was superior in throughput, cost and data resolution when compared with an experienced human technician. Integration of robotics platforms in the microbiology laboratory is a necessary advancement for future One Health AMR endeavours.

Antimicrobial Resistance in Porcine Enterococci in Australia and the Ramifications for Human Health.

Enterococci are ubiquitous opportunistic pathogens that have become a major public health issue globally. The increasing prevalence of antimicrobial resistance in hospital-adapted enterococci had been thought to originate from livestock. However, this association between livestock and hospital-adapted enterococci is currently unclear. This study investigates the antimicrobial susceptibilities of enterococci isolated from pig cecal samples and compares the genomic characteristics of Enterococcus faecium from pigs to those of isolates from meat chickens and from human sepsis cases. From 200 cecal samples, antimicrobial susceptibility testing was performed for E. faecium (n = 84), E. hirae (n = 36), and E. faecalis (n = 17). Whole-genome sequencing was performed for all E. faecium isolates, and the sequences were compared to those of previously studied isolates from meat chickens and human sepsis cases through bioinformatics analysis. Resistance (non-wild type) to erythromycin, gentamicin, tetracycline, ampicillin, daptomycin, virginiamycin, and quinupristin-dalfopristin was identified. More importantly, except for a single isolate harboring the vanC operon, no resistance was observed in the three species to vancomycin, teicoplanin, and linezolid, which are critically important antimicrobials used to treat enterococcal infections in humans. The E. faecium isolates from chickens were genetically distinct from human and pig isolates, which were more closely related. Human strains that were closely related to pig strains were not typical "hospital-adapted strains" as previously identified. The results of this study show that enterococci from Australian finisher pigs are not a source of resistance to critically important antimicrobials and that E. faecium from pigs is not part of the current human hospital-adapted population.IMPORTANCE Resistance to the critically important antimicrobials vancomycin, teicoplanin, and linezolid is not found in enterococci collected from Australian finisher pigs. However, some antimicrobial resistance was observed. In particular, resistance to quinupristin-dalfopristin, a combination of two streptogramin class antimicrobials, was identified despite the absence of streptogramin use Australia-wide since 2005. Other observed resistance among enterococci from pigs include chloramphenicol, erythromycin, and tetracycline resistance. Genomic comparison of E. faecium from Australian pigs to isolates collected from previous studies on chickens and humans indicate that E. faecium from pigs are genetically more similar to those of humans than those from chickens. Despite the increased genetic similarities, E. faecium strains from pigs are phylogenetically distinct and did not belong to the dominant sequence types found in hospital-adapted strains causing sepsis in humans. Therefore, the results indicate that Australian finisher pigs are not a source of hospital-adapted E. faecium in Australia.

Emergence of Fluoroquinolone-Resistant Campylobacter jejuni and Campylobacter coli among Australian Chickens in the Absence of Fluoroquinolone Use.

In a structured survey of all major chicken-meat producers in Australia, we investigated the antimicrobial resistance (AMR) and genomic characteristics of Campylobacter jejuni (n = 108) and C. coli (n = 96) from cecal samples of chickens at slaughter (n = 200). The majority of the C. jejuni (63%) and C. coli (86.5%) samples were susceptible to all antimicrobials. Fluoroquinolone resistance was detected among both C. jejuni (14.8%) and C. coli (5.2%), although this only included three sequence types (STs) and one ST, respectively. Multidrug resistance among strains of C. jejuni (0.9%) and C. coli (4.1%) was rare, and fluoroquinolone resistance, when present, was never accompanied by resistance to any other agent. Comparative genome analysis demonstrated that Australian isolates were found dispersed on different branches/clusters within the international collection. The major fluoroquinolone-resistant STs of C. jejuni (ST7323, ST2083, and ST2343) and C. coli (ST860) present in Australian chickens were similar to those of international isolates and have been reported previously in humans and animals overseas. The detection of a subpopulation of Campylobacter isolates exclusively resistant to fluoroquinolone was unexpected since most critically important antimicrobials such as fluoroquinolones are excluded from use in Australian livestock. A number of factors, including the low level of resistance to other antimicrobials, the absence of fluoroquinolone use, the adoption of measures for preventing spread of contagion between flocks, and particularly the genomic identities of isolates, all point to humans, pest species, or wild birds as being the most plausible source of organisms. This study also demonstrates the need for vigilance in the form of surveillance for AMR based on robust sampling to manage AMR risks in the food chain.IMPORTANCECampylobacter is one of the most common causes of gastroenteritis in humans, with infections frequently resulting from exposure to undercooked poultry products. Although human illness is typically self-limiting, a minority of cases do require antimicrobial therapy. Ensuring that Campylobacter originating from meat chickens does not acquire resistance to fluoroquinolones is therefore a valuable outcome for public health. Australia has never legalized the use of fluoroquinolones in commercial chickens and until now fluoroquinolone-resistant Campylobacter has not been detected in the Australian poultry. This structured survey of meat chickens derived from all major Australian producers describes the unexpected emergence of fluoroquinolone resistance in Campylobacter jejuni and C. coli Genetic characterization suggests that these isolates may have evolved outside the Australian poultry sector and were introduced into poultry by humans, pest species, or wild birds. The findings dramatically underline the critical role of biosecurity in the overall fight against antimicrobial resistance.

Implications of Foraging and Interspecies Interactions of Birds for Carriage of Escherichia coli Strains Resistant to Critically Important Antimicrobials.

Globally, gulls have been associated with carriage of high levels of Escherichia coli strains resistant to critically important antimicrobials (CIAs), a major concern, as these antimicrobials are the sole alternative or one among only a few alternatives available to treat severe life-threatening infections in humans. Previous studies of Australian silver gulls demonstrated high levels of resistance to CIAs, particularly fluoroquinolone and extended-spectrum cephalosporins, among E. coli strains (carriage at 24% and 22%, respectively). This study aimed to identify and characterize strains from four distinct bird species inhabiting a common coastal environment, determine the frequency of carriage of CIA-resistant E. coli strains, and examine if these resistant clones and their resistance-encoding mobile genetic elements (MGEs) could be transmitted between species. CIA-resistant E. coli was detected in silver gulls (53%), little penguins (11%), and feral pigeons (10%), but not in bridled terns. In total, 37 different sequence types (STs) were identified, including clinically significant human-associated lineages, such as ST131, ST95, ST648, ST69, ST540, ST93, ST450, and ST10. Five main mobile genetic elements associated with blaCTX-M-positive E. coli strains isolated from three bird species were detected. Examination of clonal lineages and MGEs provided indirect evidence of transfer of resistance between bird species. The carriage of CIA-resistant E. coli by gulls and pigeons with proximity to humans, and in some instances food-producing animals, increases the likelihood of further bidirectional dissemination.IMPORTANCE It has been shown that 20% of Australian silver gulls carry drug-resistant Escherichia coli strains of anthropogenic origin associated with severe diseases, such as sepsis and urinary tract infections, in humans. To further characterize the dynamics of drug-resistant E. coli in wildlife populations, we investigated the carriage of critically important antimicrobial (CIA) drug-resistant E. coli in four bird species in a common environment. Our results indicated that gulls, pigeons, and penguins carried drug-resistant E. coli strains, and analysis of mobile genetic elements associated with resistance genes indicated interspecies resistance transfer. Terns, representing a bird species that forages on natural food sources at sea and distant from humans, did not test positive for drug-resistant E. coli This study demonstrates carriage of CIA-resistant bacteria in multiple bird species living in areas commonly inhabited by humans and provides further evidence for a leapfrog effect of resistance in wildlife, facilitated by feeding habits.

Fall Prevention Conceptual Framework.

Falls can have lasting psychological and physical consequences, particularly fractures and slow- healing processes, and patients may also lose confidence in walking. Injuries from falls lead to functional decline, institutionalization, higher health care costs, and decreased quality of life. The process related to the problem of patient falls in the hospital, using the nursing model developed by the theorist, Ida Jean Orlando, is explained in this article. The useful tool that provides guidance to marketers in this endeavor is Maslow's hierarchy of needs. During acute illness, individuals are greatly in need of satisfying their physiological needs. If these needs are not met, patients leave the hospital lacking a positive experience. Initial fall risk assessment is critical to plan intervention and individualize care plan. Interventions depend on the severity of fall risk factors.

Increasing Registered Nurse Retention Using Mentors in Critical Care Services.

Recruiting and training 1 newly hired registered nurse can cost thousands of dollars. With a high percentage of these newly hired nurses leaving their first place of employment within their first year, the financial implications may be enormous. It is imperative that health care facilities invest in recruiting and retention programs that retain high-quality nurses. Mentorship programs in retaining and easing the transition to practice for new graduate nurses, re-entry nurses, and nurses new to a specialty area are critical in nurse retention. Discussion in this study includes the effect of implementing a mentor program into the critical care services area of a 325-bed not-for-profit community hospital in northern Indiana. Based on this study, nurses with a mentor were retained at a 25% higher rate than those not mentored. Implementation of a mentor program reduced the training cost to the facility and increased retention and morale.

A Qualitative Study of the Change-of-Shift Report at the Patients' Bedside.

Concerns about patient bedside change-of-shift reporting at a community hospital in northern Indiana stimulated the development of this qualitative phenomenological study. A review of the literature revealed a research deficit in acute care nurses' perceptions of bedside reporting in relation to compliance. The research question addressed in this study was, "What are acute care nurses' perceptions of the change-of-shift report at the patients' bedside?" Personal interviews were conducted on 7 medical, surgical, and intensive care unit nurse participants at a community hospital in northern Indiana. Five themes were identified from the collected data, which included the time factor, continuity of care, visualization, and challenges in the communication of discreet information.

Night Shift Work and Its Health Effects on Nurses.

The purpose of this research was to study night shift work and its health effects on nurses. This was a quantitative study using descriptive design; it also incorporated three qualitative open-ended questions to complement the study. The data were collected using Survey Monkey, with an Internet based confidential data collection tool. The population of relevance to this study was nurses employed in hospital settings in the United States. E-mail addresses and Facebook were used to recruit participants. Results indicated that there is an increased risk of sleep deprivation, family stressors, and mood changes because of working the night shift. Rotating shifts were mentioned as a major concern for night shift nurses. Respondents agreed that complaints about fatigue and fatigue related illnesses in night shift workers were ignored. There was also a general perception among nurses working the night shift that sleep deprivation leads to negative health consequences including obesity; however, they were not as high a concern as rotating shifts or fatigue.

Severe Disease Caused by Community-Associated MRSA ST398 Type V, Australia, 2017.

Using whole-genome sequencing, we identified a community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) sequence type (ST) 398 type V (5C2&5) isolate (typically found in China) in Australia in 2017. This CA-MRSA ST398 variant was highly virulent, similar to other related CA-MRSAs of ST398. This strain should be monitored to prevent more widespread dissemination.

Genomic, Antimicrobial Resistance, and Public Health Insights into Enterococcus spp. from Australian Chickens.

Due to Australia's management of antimicrobial use in poultry, particularly the discontinued use of avoparcin for nearly 20 years, it is hypothesized that vancomycin-resistant enterococci associated with human disease are not derived from poultry isolates. This study evaluated antimicrobial resistance (AMR) of five enterococcal species isolated from Australian meat chickens, genomic features of Enterococcus faecium and Enterococcus faecalis, and the phylogenetic relationship of the poultry-derived E. faecium with isolates from human sepsis cases. All enterococcal isolates from chicken ceca were subjected to antimicrobial susceptibility testing. E. faecium and E. faecalis underwent whole-genome sequencing. E. faecium was compared at the core genome level to a collection of human isolates (n = 677) obtained from cases of sepsis over a 2-year period spanning 2015 to 2016. Overall, 205 enterococci were isolated consisting of five different species. E. faecium was the most frequently isolated species (37.6%), followed by E. durans (29.7%), E. faecalis (20%), E. hirae (12.2%), and E. gallinarum (0.5%). All isolates were susceptible to vancomycin and gentamicin, while one isolate was linezolid resistant (MIC 16 mg/liter). Core genome analysis of the E. faecium demonstrated two clades consisting predominantly of human or chicken isolates in each clade, with minimal overlap. Principal component analysis for total gene content revealed three clusters comprised of vanA-positive, vanB-positive, and both vanA- and vanB-negative E. faecium populations. The results of this study provide strong evidence that Australian chicken E. faecium isolates are unlikely to be precursor strains to the currently circulating vancomycin-resistant strains being isolated in Australian hospitals.

Resistance to critically important antimicrobials in Australian silver gulls (Chroicocephalus novaehollandiae) and evidence of anthropogenic origins.

OBJECTIVES: Antimicrobial resistance (AMR) to critically important antimicrobials (CIAs) amongst Gram-negative bacteria can feasibly be transferred amongst wildlife, humans and domestic animals. This study investigated the ecology, epidemiology and origins of CIA-resistant Escherichia coli carried by Australian silver gulls (Chroicocephalus novaehollandiae), a gregarious avian wildlife species that is a common inhabitant of coastal areas with high levels of human contact. METHODS: Sampling locations were widely dispersed around the perimeter of the Australian continent, with sites separated by up to 3500 km. WGS was used to study the diversity and molecular characteristics of resistant isolates to ascertain their epidemiological origin. RESULTS: Investigation of 562 faecal samples revealed widespread occurrence of extended-spectrum cephalosporin-resistant (21.7%) and fluoroquinolone-resistant (23.8%) E. coli. Genome sequencing revealed that CIA-resistant E. coli isolates (n = 284) from gulls predominantly belonged to human-associated extra-intestinal pathogenic E. coli (ExPEC) clones, including ST131 (17%), ST10 (8%), ST1193 (6%), ST69 (5%) and ST38 (4%). Genomic analysis revealed that gulls carry pandemic ExPEC-ST131 clades (O25:H4 H30-R and H30-Rx) and globally emerging fluoroquinolone-resistant ST1193 identified among humans worldwide. Comparative analysis revealed that ST131 and ST1193 isolates from gulls overlapped extensively with human clinical isolates from Australia and overseas. The present study also detected single isolates of carbapenem-resistant E. coli (ST410-blaOXA-48) and colistin-resistant E. coli (ST345-mcr-1). CONCLUSIONS: The carriage of diverse CIA-resistant E. coli clones that strongly resemble pathogenic clones from humans suggests that gulls can act as ecological sponges indiscriminately accumulating and disseminating CIA-resistant bacteria over vast distances.

A Correlational Study of Spiritual Well-being and Depression in the Adult Cancer Patient.

Depression in adult cancer patients has been widely studied, along with spiritual effects of traumatic events and even spiritual growth after a diagnosis of cancer. There has been limited research determining a direct correlation between spiritual well-being and depression in adult cancer patients. The purpose of this research study was to examine the relationship between spiritual well-being and depression in adult cancer patients. This was a descriptive correlational study using 59 patients older than 18 years from an outpatient cancer center. The researchers hypothesized that patients with a low spiritual well-being score would be more likely to have a high depressive symptom score, thus providing support for a correlation between cancer patient's spiritual well-being and risk of depression. Implications of this study lead to evidence for better screening processes for cancer patients regarding spiritual well-being.

Perceptions of College Student-Athletes Regarding the Long-Term Effects of Concussions.

A comprehensive review of the literature was completed to investigate college student-athletes' perceptions regarding the long-term effects of concussions. Based on the findings, it was determined that there is a need for more education among student-athletes regarding this topic. This was a quantitative, cross-sectional, nonexperimental study with a descriptive design. A survey with 7 demographic and 17 Likert-type statements was collected from 100 student-athletes in a Midwestern college at their specified team practice sites for data collection.

Results indicated that there is an increased risk of sleep deprivation, family stressors, and mood changes because of working the night shift. Rotating shifts were mentioned as a major concern for night shift nurses. Respondents agreed that complaints about fatigue and fatigue-related illnesses in night shift workers were ignored. There was also a general perception among nurses working the night shift that sleep deprivation leads to negative health consequences including obesity; however, they were not as high a concern as rotating shifts or fatigue.

A Qualitative Study of Health Care Experiences Among International Students.

The purpose of this qualitative study was to explore the health care experiences of international students at a college in Indiana. The study answered the following research question: What are the lived experiences of international students while seeking health care? This research question was identified after a literature review, which showed a lack of research regarding international students' health care experiences. The data in this study were collected through in-depth interviews with 5 participants who resided at the college. After the interviews, the identification of themes and the analysis of results revealed the international students' lived experiences and perceptions of health care in the United States.
