Abstract
SPT0346-52 is one of the most most luminous and intensely star-forming galaxies in the universe, with

and

. In this paper, we present

ALMA observations of the

158 μm emission line in this z = 5.7 dusty star-forming galaxy. We use a pixellated lensing reconstruction code to spatially and kinematically resolve the source-plane

and rest-frame 158 μm dust continuum structure at ∼700 pc (∼0.″12) resolution. We discuss the

deficit with a pixellated study of the L
[C ii]/L
FIR ratio in the source plane. We find that individual pixels within the galaxy follow the same trend found using unresolved observations of other galaxies, indicating that the deficit arises on scales ≲700 pc. The lensing reconstruction reveals two spatially and kinematically separated components (∼1 kpc and ∼500 km s−1 apart) connected by a bridge of gas. Both components are found to be globally unstable, with Toomre Q instability parameters

everywhere. We argue that SPT0346-52 is undergoing a major merger, which is likely driving the intense and compact star formation.
Magnetically Inspired Explosive Outflows from Neutron-star Mergers
Authors: Nathanail Antonios , Porth Oliver , Rezzolla Luciano 
Published: January 2019

Abstract
Binary neutron-star mergers have long been associated with short-duration gamma-ray bursts (GRBs). This connection was confirmed with the first coincident detection of gravitational waves together with electromagnetic radiation from GW170817. The basic paradigm for short-duration GRBs includes an ultra-relativistic jet, but the low-luminosity prompt emission together with follow-up radio and X-ray observations have hinted that this picture may be different in the case of GW170817. In particular, it has been proposed that large amounts of the magnetic energy that is amplified after the merger, can be released when the remnant collapses to a black hole, giving rise to a quasi-spherical explosion impacting on the merger ejecta. Through numerical simulations we investigate this scenario for a range of viewing angles, injected energies and matter densities at the time of the collapse. Depending on the magnitude of the energy injection and the remnant density, we find two types of outflows: one with a narrow relativistic core and one with a wide-angle, but mildly relativistic outflow. Furthermore, very wide outflows are possible, but require energy releases in excess of 1052 erg.

Published: January 2019

Introduction: Lactobacillus dominated vaginal microenvironment is associated with lower risk of genital infections. Numerous studies have reported geographic and ethnic variations in vaginal microbiome structure between healthy individuals from different race and ethnicity. India has a great diversity, so it is intriguing to find out if such divergences exist in vaginal lactobacilli. The present study aimed to investigate predominant Lactobacillus species in vaginas of healthy Indian women and screen isolates for lactic acid and H2O2 production.
Methodology: 203 premenopausal women asymptomatic for any vaginal complaints were recruited. The lactobacilli isolates on MRS agar were identified by Multiplex-PCR and 16sRNA gene sequencing. RAPD was used to differentiate strains of same species. H2O2 and lactic acid was evaluated on TMB-HRP MRS agar and BCP-MRS agar respectively.
Results: Lactobacilli were recovered from 107/109 (98.2%) women with normal microflora. L. iners 64.7% (68), L. crispatus 26.7% (28), L. reuteri 21.9% (23), L. jensenii 16.2% (17) and L. gasseri 15.2% (16) were the most frequently occurring vaginal lactobacilli in normal women. The vaginal microflora was dominated by either by a single (80%, n = 84) or a combination (20%, n = 21) of Lactobacillus species. Though most frequently identified, L. iners, coexisted only with other Lactobacillus species. All isolates were acid producers but H2O2 was produced by 94.2% isolates.
Conclusions: Our study reports prevalent vaginal lactobacilli which could be explored as probiotics. Presence of heterogeneous Lactobacillus population highlights the cumulative effects of different lactobacilli maintaining vaginal health. Contrasting observations about L. iners reiterates its puzzling role in vaginal immunity, advocating further research.

Published: January 2019

Introduction: Whole genome sequencing (WGS) has shown superiority over other bacterial typing methods and can be used to monitor disease transmission. The long culture period hinders use of WGS as a diagnostic tool for TB. The ideal situation would be to efficiently sequence directly from clinical specimens such as sputum. Attempts to sequence directly from Mtb clinical samples have achieved very low coverage (less than 0.7X). We compared DNA extraction methods for direct extraction from Mycobacterium tuberculosis positive sputum and assessed their suitability for Single Molecule Real Time sequencing.
Methodology: We evaluated the extraction efficiency of the PrimeXtract kit and an in-house CTAB method by extracting DNA from Mtb sputum. We evaluated the methods on these parameters: ease of use, efficiency (quantity and purity) and the cost per extraction.
Results: The PrimeXtract kit was able to isolate 5.93 µg/mL ± 0.94, (Mean ± SEM) concentration of DNA and a yield of 0.2975 µg ± 0.04723, (Mean ± SEM). Comparatively, the CTAB method isolated 1.88 µg/mL ± 0.38 DNA and a yield of 0.09 µg ± 0.02. Both concentration and yield from the kit were significantly (p = 0.0002) higher than those from CTAB. The PrimeXtract kit had a DNA purity ratio of 1.69 ± 0.09 compared to the CTAB’s 1.73 ± 0.14 and this difference was not statistically different.
Conclusion: PrimeXtract kit has a superior extraction efficiency than the CTAB method on Mtb sputum in terms of DNA yield although no significant difference by DNA purity was seen.

Published: January 2019

Introduction: We aimed to describe incidence, outcomes and antimicrobial resistance markers of causative agents of bacterial BSI in the intensive care unit (ICU) in a trauma center in Serbia.
Methodology: Prospective surveillance was conducted from November 2014 to April 2016 in two trauma-surgical ICUs of the Emergency Department of Clinical center of Serbia. Bloodstream infections were diagnosed using the definitions of Center for Disease Control and Prevention.
Results: Out of 406 trauma patients, 57 had at least one episode of BSI (cumulative incidence 14.0%). Overall 62 BSI episodes were diagnosed (incidence rate 11.8/1000 patient/days), of which 43 (69.4%) were primary BSI (13 catheter-related BSI and 30 of unknown origin) and 19 (30.6%) were secondary BSI. The most common isolated pathogen was Acinetobacter spp. [n = 24 (34.8%)], followed by Klebsiella spp. [n = 17 (24.6%)] and P. aeruginosa [n = 8 (1.6%)]. All S. aureus [n = 6 (100%)] and CoNS [n = 3 (100%)] isolates were methicillin resistant, while 4 (66%) of Enterococci isolates were vacomycin resistant. All isolates of Enterobacteriaceae were resistant to third-generation cephalosporins [n = 22 (100%)] while 7 (87.5%) of P. aeruginosa and 23 (95.8%) of Acinetobacter spp. isolates were resistant to carbapenems. All-cause mortality and sepsis were significantly higher in trauma patients with BSI compared to those without BSI (P < 0.001 each).
Conclusions: BSI is a common healthcare-associated infection in trauma ICU and it is associated with worse outcome. Better adherence to infection control measures and guidelines for prevention of primary BSI must be achieved.

How Many Is Too Many? Collaboration of Multiple Nursing Organizations For Professional Development
Authors: Redding Donna A , Anglin Linda T 
Published: January 2019

ABSTRACT
Representatives of 11 nursing organizations developed a unique consortium to produce an ongoing series of annual conferences focused on promoting professional nursing leadership among nurses in diverse practice areas including acute care, long-term care, community health, and nursing education. The consortium strategically added members and refined the format of the conferences based on participant feedback. The conferences feature a keynote speaker and practicebased breakout sessions designed to facilitate futuristic thinking among nurses. The conference is associated with a legislative roundtable to support interaction between nurses and legislators. Future expansion of the consortium will include representation of advanced practice nurses.
The development of the consortium and its highly efficient methods of operation are described in this article as an example of multi-organizational collaboration to promote professional nursing leadership. Bonds have been formed between the consortium member organizations that are mutually beneficial to the members of all.

Published: January 2019

ABSTRACT
Background: The purpose of this study was to examine the differences in health care professionals' perceptions of perinatal loss situations before and after an educational program on perinatal bereavement.
Method: A quasi-experimental design was used in a pretest and posttest format.
Results: Scores were significantly higher (p = .000) on each of the posttest vignettes. Overall scores were lowest for the miscarriage pretest, whereas scores for the pretest vignettes for the stillbirth and neonatal loss were similar. A similar pattern occurred in the posttest vignette scores.
Conclusion: Health care professionals' perceptions of the emotional care needs of families experiencing perinatal loss were significantly increased after an educational program. The miscarriage vignette had the largest change score and the lowest mean scores on the pretest and posttest, which indicates professionals do not view miscarriage as significant a loss as stillbirth and neonatal loss.

Authors: Berarducci Adrienne , Lengacher Cecile A , Keller Rosemary 
Published: January 2019

ABSTRACT
Background: Osteoporosis has rapidly evolved into a severe health threat to Americans and a major public health problem. The increasing incidence of this disease and related fractures mandates that continuing education include osteoporosis content to ensure nurses provide competent education and care. An osteoporosis educational program was presented to nurses as part of a continuing education symposium on women's health issues. The program was tested to determine its effectiveness in augmenting the osteoporosis-related knowledge and attitudes of nurses.
Method: Eighty-one RNs with educational levels varying from associate degrees to doctorates attended the continuing education program. Sixty-three of the program participants completed pretest and posttest measures.
Findings: The educational program significantly increased osteoporosis knowledge in this cohort of nurses. Additionally/ nurses indicated they were more likely to pay attention to their own bone health as a result of attending the program.
Conclusion: Results of this study reinforce the need for osteoporosis-related continuing education.

Authors: Rose Molly A , Larrimore Karen L 
Published: January 2019

ABSTRACT
Background: A survey on knowledge and awareness concerning chemical and biological terrorism was used to assess the knowledge base of health care providers at an urban medical center in preparation for developing a workshop on domestic terrorism preparedness. A second survey assessing domestic terrorism preparedness of infection control personnel and nurse educators also was conducted.
Method: A total of 291 nurses, physicians, nursing students, and medical students completed the knowledge and awareness survey. A total of 24 infection control personnel and nurse educators completed the second survey on domestic terrorism preparedness.
Findings: The knowledge scores of the respondents were low, with less than one fourth of the knowledge questions answered correctly. In addition, less than 23% of the respondents reported confidence to provide health care in a hypothetical chemical terrorism situation.
Conclusion: These findings indicate a need for nurses in continuing education and staff development to develop, implement, and evaluate innovative domestic terrorism preparedness programs.
Continuing Education in Research Ethics for the Clinical Nurse
Authors: Jeffers Brenda Recchia 
Published: January 2019

ABSTRACT
Background: In their role as care provider, clinical nurses are involved in research protocols. Although clinical nurses seldom serve as principal investigators, nursing care often is delivered to patients involved in study protocols. This article explores the need for continuing education in research ethics for clinical nurses and offers recommendations for core research ethics education.
Method: Professional nursing statements, federal policy, and federal recommendations for improving protection of human participants in research were reviewed to identify areas pertinent to the role of nurses.
Findings: Continuing education in research ethics is an important component in ensuring protection of human participants in research. Essential research ethics education topics for clinical nurses, including three case studies, are presented.
Conclusion: Continuing education that enhances clinical nurses' awareness of the ethical issues involved in research assures nurses have the knowledge and ethical sensitivity needed to act as patient advocates and improves the protection of human rights.
