The final constructivist process revealed a nursing-specific theory human-centred leadership in health care uniquely suited to assist leaders in addressing structure, process and outcomes.

Efforts by nurse leaders to test the theory with metrics related to nursing excellence will result in validation of the theory and validation of the proposed sustained culture change.

To examine socio-demographic and health-related factors associated with latent tuberculosis infection (LTBI) treatment refusal, non-initiation, and non-completion among a cohort of Vietnamese immigrants.

This is a retrospective cohort study in which LTBI charts were reviewed at a public health clinic in Orange County, California between January 2010 and August 2011.

Altogether, 474 patient charts with documented LTBI treatment were reviewed for patients who met the inclusion criteria.

Univariate and multivariate analyses were used to identify socio-demographic and health-related factors associated with LTBI treatment refusal, non-initiation, and non-completion.

Of the 474 charts reviewed, 171(36.1%) patients refused LTBI treatment and 21(6.9%) accepted but did not initiate. Of the 282 that started treatment, 62 (22.0%) did not complete the regimen prescribed. The primary barrier documented for treatment refusal and non-completion was concern about medication side effects. Other barriers to treatment non-completion include transportation issues and conflicts with travel plans or work schedules.

Community and public health nurses working with the Vietnamese immigrant population can play a vital role in improving patients' LTBI treatment acceptance, initiation, and completion. A proactive approach to addressing barriers and potential medication side effects can improve overall treatment success.

Metallophore-mediated metal uptake pathways necessitate complex cycles of synthesis, secretion, and recovery of the metallophore across the bacterial envelope. We recently discovered staphylopine and pseudopaline, two members of a new family of broad-spectrum metallophores important for bacterial survival during infections. Here, we are expending the molecular understanding of the pseudopaline transport cycle across the diderm envelope of the Gram-negative bacterium Pseudomonas aeruginosa. We first explored pseudopaline secretion by performing in vivo quantifications in various genetic backgrounds and revealed the specific involvement of the MexAB-OprM efflux pump in pseudopaline transport across the outer membrane. We then addressed the recovery part of the cycle by investigating the fate of the recaptured metal-loaded pseudopaline. To do so, we combined in vitro reconstitution experiments and in vivo phenotyping in absence of pseudopaline transporters to reveal the existence of a pseudopaline modification mechanism, possibly involved in the metal release following pseudopaline recovery. Overall, our data allowed us to provide an improved molecular model of secretion, recovery, and fate of this important metallophore by P. aeruginosa.Endometriosis is a chronic disease that commonly affects women in their reproductive age. It has been reported that the infertility due to endometriosis is largely caused by pelvic adhesion, oocyte damage, and so on. There are several causes of endometriosis including bacterial infections, immunological abnormalities, epigenetics, and aberrant DNA methylation. The natural killer (NK) cells present in the peritoneal fluid express CD16 and CD56. They also express NK cell inhibitory receptors and activating receptors and usually work to eliminate endometrial cells in the retrograde menstruation. However, in women with endometriosis, the changes in these receptors and production of cytokines by NK cells cause the onset and progression of endometriosis. In this review, we have focused on the role of NK cells in pelvic endometriosis and presented the immunological abnormalities in endometriosis including the possibility of future treatment.

This study aimed to investigate the antitumor activity of paclitaxel with radiation and sorafenib in anaplastic thyroid cancer (ATC) cells in vitro and in vivo.

The 8505C ATC cell line was exposed to radiation, sorafenib, and paclitaxel each or in combination. find more The effects of combined treatment on the cell cycle and intracellular signaling pathways were assessed using flow cytometry and western blot analysis. An ATC cell line xenograft model was used to examine antitumor activity in vivo.

Radiation, paclitaxel plus sorafenib synergistically decreased cell viability in ATC cells and significantly increased apoptotic cell death. The combination of paclitaxel, sorafenib with radiation reduced the antiapoptotic factor in ATC. This combination therapy significantly reduced the tumor volume and increased survival in the ATC xenograft model.

These results suggest that the combination of radiation and paclitaxel plus sorafenib has significant anticancer activity in preclinical models.

To evaluate the feasibility and potential effects of patient-centred self-administered acupressure for alleviating fatigue and co-occurring symptoms among Chinese advanced cancer patients receiving treatment.

Thirty advanced cancer patients who screened positive for moderate/severe fatigue with symptoms of insomnia and/or pain were recruited from a hospital in Hong Kong. They were randomly assigned (11) to receive a 4-week patient-centred self-administered acupressure intervention or health education. Fatigue (primary outcome) and secondary outcomes (sleep quality, pain, fatigue-sleep disturbance-pain symptom cluster severity, anxiety, depression and quality of life) were measured by questionnaires and actigraphy.

Twenty-four participants (80%) completed the study. Adherence to self-administered acupressure practice was satisfactory, with all retained participants attending all sessions and 90.9% practising acupressure daily. All completers rated the class as very enjoyable or quite enjoyable. Fatigue, pain, symptom cluster severity, anxiety, depression and quality of life appeared to improve from baseline to post-intervention in the intervention group.
