Cognitive rehabilitation combined with drug treatment in Alzheimer's disease patients: a pilot study

OBJECTIVE: To study the efficacy of cognitive rehabilitation combined with acetylcholinesterase inhibitor (AChE-I) treatment in patients with mild Alzheimer's disease and their relatives. METHOD: Thirteen patients with mild Alzheimer's disease treated with rivastigmine 6-12 mg/day for more than two months started cognitive rehabilitation training. Before and after the cognitive rehabilitation training patients were assessed through cognitive tests, activities of daily living scale, neuropsychological battery and scales to evaluate caregivers' depressive and anxiety symptoms. Six patients were randomized to a combined treatment group (AChE-I plus cognitive rehabilitation and caregiver support) and seven patients to a control group (AChE-I only) and followed up for five months. RESULTS: Mini-Mental State Examination (MMSE) scores (p = 0.047) and backward digit span scores (p = 0.018) were significantly different between the groups on follow-up. The combined treatment group showed a better positive treatment effect on cognitive and neuropsychological tests applied to patients and reduction of psychiatric symptoms was observed in their caregivers (nonsignificant). CONCLUSION: Cognitive rehabilitation associated with AChE-I treatment can potentially be useful to stabilize or improve cognitive and functional performance of patients with mild Alzheimer's disease and can reduce caregivers' psychiatric symptoms.     

Rethinking cultural safety while waiting to do fieldwork: methodological implications for nursing research

The concept of culture has been widely applied as an explanatory concept within health care, often within a framework representing culture as a fixed, reified entity, with cultural groups existing in a binary sense vis-;-vis mainstream culture. However, if our scholarship is to generate knowledge that addresses longstanding patterns of inclusion and exclusion along lines such as race, ethnicity, class, and gender, interpretive frames are needed that account for culture as embedded in fields of power relations; as mediated by social forces such as economics, politics, and historical patterns of oppression and colonization; and as being constantly renegotiated. In this article we trace a series of theoretical explorations, centered on the concept of cultural safety, with corresponding methodological implications, engaged in during preparation for an intensive period of fieldwork to study the hospitalization and help-seeking experiences of diverse ethnocultural populations.     

Some patients (and some of us) respond better to some biological therapies: the as yet unsolved conundrum

Very often, treatment for many common musculoskeletal conditions is only palliative, or involves surgery with major shortcomings. Biological interventions—in particular, platelet-rich plasma (PRP) therapies—may well provide more effective treatments, but their actual efficacy is under scrutiny. PRP is biologically unique to each individual depending on endogenous and exogenous factors, including, but not limited to, demographic factors (i.e. age), immune status (i.e. microbiota), metabolic diseases and concomitant medications. All these potential modifiers of the ultimate effects of PRP have been poorly explored, and their relationship with efficacy has not been established.     

Neutrophil derived CSF1 induces macrophage polarization and promotes transplantation tolerance

The colony‐stimulating factor 1 (CSF1) regulates the differentiation and function of tissue macrophages and determines the outcome of the immune response. The molecular mechanisms behind CSF1‐mediated macrophage development remain to be elucidated. Here we demonstrate that neutrophil‐derived CSF1 controls macrophage polarization and proliferation, which is necessary for the induction of tolerance. Inhibiting neutrophil production of CSF1 or preventing macrophage proliferation, using targeted nanoparticles loaded with the cell cycle inhibitor simvastatin, abrogates the induction of tolerance. These results provide new mechanistic insights into the developmental requirements of tolerogenic macrophages and identify CSF1 producing neutrophils as critical regulators of the immunological response.     

Outcomes of Mental Health Screening for United Kingdom Nationals Affected by the 2015–2016 Terrorist Attacks in Tunisia,Paris, and Brussels

Following several terrorist attacks in 2015 and 2016, a national program was set up to identify and support residents of England whose mental health had been affected. We report the outcomes of the program's screening and assessment components. Questionnaires and information about the program were mailed to 483 people and 49 families known to the police. Individuals who screened positive on an assessment for posttraumatic stress disorder, anxiety, depression, increased smoking, or problematic alcohol consumption were offered clinical assessment and referred to an appropriate National Health Service (NHS) service, if required. Of the 195 eligible people who returned our questionnaires, 179 (91.8%) screened positive on one or more measure. Following clinical assessment, 78 adults and three children were referred for treatment. The program was broadly successful in facilitating access to services. However, most people who had been directly exposed to the attacks did not participate and data protection issues limited communication with those who were affected. Further discussion of data protection concerns may help future programs operate more efficiently.     

Efficacy,Predictive Factors,and Prediction Nomograms for 68Ga-labeled Prostate-specific Membrane Antigen–ligand Positron-emission Tomography/Computed Tomography in Early Biochemical Recurrent Prostate Cancer After Radical Prostatectomy

Recently, ⁶⁸Ga-labeled prostate-specific membrane antigen (PSMA)–ligand positron-emission tomography (PET) imaging has been shown to improve detection rates in recurrent prostate cancer (PC). However, published studies include only small patient numbers at low prostate-specific antigen (PSA) values. For this study, 272 consecutive patients with biochemical recurrence after radical prostatectomy and PSA value between 0.2 and 1 ng/ml were included. The ⁶⁸Ga-PSMA-ligand PET/computed tomography (CT) was evaluated, and detection rates were determined and correlated to various clinical variables using univariate and multivariable analyses. Subgroups of patients with very low (0.2–0.5 ng/ml) and low (>0.5–1.0 ng/ml) PSA values were analyzed. In total, lesions indicative of PC recurrence were detected in 55% (74/134) and 74% (102/138) with very low and low PSA values, respectively. Main sites of recurrence were pelvic or retroperitoneal lymph nodes metastases, followed by local recurrence and bone metastases with higher probability in the low versus very low PSA subgroup. Detection rates significantly increased with higher PSA values, primary pT ≥ 3a, primary pN+ disease, grade group ≥4, previous radiation therapy, and concurrent androgen deprivation therapy (ADT) in univariate analysis. In a multivariable logistic regression model, concurrent ADT and PSA values were identified as most relevant predictors of positive ⁶⁸Ga-PSMA-ligand PET/CT. Further, prediction nomograms were established, which may help in estimating pretest PSMA-ligand PET positivity in clinical practice.

Changes in Nursing Education in the European Union

PURPOSE: To provide an overview of changes in nursing education in the European Union (EU) within the framework of the Bologna Declaration, signed in 1999 by the European ministers of education, and to describe specific efforts and changes in Spain. ORGANIZING CONSTRUCTS: (a) the Bologna Declaration process, its recent reforms in all disciplines including nursing, and perspectives on future developments; (b) the Tuning Project, designed and carried out by a group of European universities to meet the challenges posed by the Bologna Declaration; and (c) efforts in a group of Spanish universities to promote higher education in nursing. FINDINGS AND CONCLUSIONS: These changes promote enhanced academic recognition, professionalism in nursing education, and graduates' competencies in practice in most European countries by specifying the undergraduate nursing degree as the minimal entrance level for practice and master's and doctoral programs for further career development.     

Evaluation of disk diffusion method for determining eberconazole susceptibility of dermatophytes and influence of culture medium

We have evaluated a disk diffusion method to determine the activity of eberconazole against 50 strains of dermatophytes by testing three culture media (RPMI, antibiotic medium 3, and high resolution). No differences were found among the results obtained with the three media. A significant correlation between disk diffusion and microdilution methods was observed with AM3.     

Integration between the cranial boundaries of the nasopharynx and the upper cervical vertebrae in Homo and Pan

The nasopharynx is an important anatomical structure involved in respiration. Its bony boundaries, including the basicranium and upper cervical vertebrae, may be subject to selective pressures and constraints related to respiratory function. Here, we investigate phenotypic integration, or covariation, between the face, the basicranial boundaries of the nasopharynx, and the atlas and axis to understand constraints affecting these structures. We collected three-dimensional coordinate data from a sample of 80 humans and 44 chimpanzees, and used two-block partial least squares to assess RV (a multivariate generalization of Pearson's r²), r_PLS, the covariance ratio, and effect size for integration among structures. We find that integration is significant among some of these structures, and that integration between the basicranial nasopharynx and vertebrae and between the face and vertebrae is likely independent. We also find divergences in the pattern of integration between humans and chimpanzees suggesting greater constraints among the human face and nasopharynx, which we suggest are linked to divergent developmental trajectories in the two taxa. Evolutionary changes in human basicranial anatomy, coupled with human-like developmental trajectories, may have required that the face grow to compensate any variation in nasopharyngeal structure. However, we were unable to determine whether the nasopharynx or the face is more strongly integrated with the vertebrae, and therefore whether respiration or biomechanical considerations related to positional behavior may be more strongly tied to vertebral evolution. Future work should focus on greater sample sizes, soft tissue structures, and more diverse taxa to further clarify these findings.
