Patients' accounts of the differences in nurses' and general practitioners' roles in primary care.

AIM This paper reports a study of patients' accounts of the differences in nurses' and general medical practitioners' roles in primary care. BACKGROUND Nurses are now diagnosing and treating illnesses including conducting first contact care consultations. However, the findings of international studies reporting patients' views of developments in nursing roles are not consistent. Whilst some studies report higher satisfaction following nurse consultations, others suggest that patients do not want nurses to replace general medical practitioners. Healthcare professionals' views of the boundaries of their roles have been studied, but patients' views have not been reported. METHOD Semi-structured interviews were conducted with 28 adults attending general practices for urgent 'same day' appointments during 2004. Participants were interviewed prior to their consultation with either the nurse or general medical practitioner and 19 participants were interviewed after the consultation. Data collection and analysis were concurrent, and based on the constant comparative method. FINDINGS Participants' views reflected traditional hierarchies in primary care. They preferred to consult with general medical practitioners if they perceived their symptoms to be serious and with nurses for minor symptoms and reassurance. They thought that nurses had more time for them and were more compassionate. Interpersonal/relational continuity of care was important and for most participants this was with a general medical practitioner who knew them. Participants trusted known practitioners; they also placed trust in professional groups and familiar structures such as the practice. CONCLUSION New nursing services should incorporate patients' views on continuity of care provider when developing models of care delivery. Patient information leaflets in general practices should be used to explain the roles of general practitioners and nurse practitioners/practice nurses. As these roles develop further, more research is needed into all aspects of their implementation and patients' views should particularly be evaluated.
Metamemory in children with autism: exploring "feeling-of-knowing" in episodic and semantic memory.

BACKGROUND Autism spectrum disorder (ASD) is a neurodevelopmental disorder primarily affecting social function and communication. Recently, there has been an interest in whether people with ASD also show memory deficits. Studies in ASD have revealed subtle impairments on tasks requiring participants to learn new information (episodic memory), but intact performance on general knowledge tasks (semantic memory). The novelty of this study was to explore metamemory (i.e., awareness of memory performance) and to examine whether children with ASD suffer from a generalized metamemory deficit common to all forms of memory, or would only present deficits on episodic metamemory tasks. METHOD To assess metamemory functioning we administered 2 feeling-of-knowing (FOK) tasks, 1 for episodic and 1 for semantic materials. In these tasks, participants are asked to predict the likelihood of subsequently recognizing currently unrecalled information. RESULTS It was found that children with autism made inaccurate FOK predictions, but only for episodic materials. CONCLUSION A specific deficit in meta-cognition emerges for only one set of materials. We argue that this deficit can be conceived of as reflecting a deficit in recollection, stemming from an inability to cast the self in the past and retrieve information about the study episode.
Intrinsic morphological diversity of thick‐tufted layer 5 pyramidal neurons ensures robust and invariant properties of in silico synaptic connections

Non‐technical summary Pyramidal neurons are output neurons of the neocortex. The thick‐tufted layer 5 (TTL5) pyramidal neurons are one of the most extensively studied neocortical cell types and are characterized by an exquisite morphological structure. Despite their characteristic morphology, TTL5 neurons in the neocortical microcircuit display an intrinsic diversity that renders each neuron morphologically unique. In order to investigate the functional significance of this intrinsic morphological diversity, we reconstructed networks of TTL5 neurons through a detailed computer model and compared the properties of modelled synaptic connections against experimental data. We found that the average synaptic properties of modelled connections between TTL5 neurons closely matched experimental observations and remained unaltered by changes to several parameters at the local network level. These results show that the intrinsic morphological diversity of TTL5 neurons is a mechanism to ensure that the average synaptic properties are robust to changes at the local network level.
The anti-nutritional factors in forages - A review

The toxicity due to the consumption of various forages is very common among the farm animals. The anti-nutritional factors present in the forages are mainly responsible for this. In this review paper, the common anti-nutritional factors viz., nitrates, oxalates, HCN and tannins present in different fodder crops have been discussed with reference to their toxic levels, symptoms and preventive measures to be taken for their safe feeding to dairy animals.
The Journey of Discovering Compassionate Listening

This article presents the concept of “compassionate listening” in critical life moments to gain insight into the process of listening with compassion. This insight evolved through a process of layered reflection using a series of texts, particularly stories that captured critical moments in working with people who were facing crisis situations or who were dying. Writing and reflecting on these stories enabled me to identify how I engaged with patients and their loved ones as a palliative care nurse specialist. I was able to explore how compassionate listening could be used to ascertain their needs, particularly when they were unable or unsure of how to proceed.
A 52mW full HD 160-degree object viewpoint recognition SoC with visual vocabulary processor for wearable vision applications

A wearable 1920×1080 160-degree object viewpoint recognition SoC is realized on a 6.38mm2 die with 65nm CMOS technology. This system focuses on enhancing the capability for wide viewpoint and long-distance recognition while reducing the computation of feature matching process. The recognition accuracy is improved from 29% to 94% under full HD resolution for a 50m-far traffic light compared with the performance under VGA (640×480). Object viewpoint prediction (OVP) supports 160-degree object viewpoint differences. 85% of power consumption and 75% of memory bandwidth are reduced via proposed visual vocabulary processor (VVP). 52mW power consumption with 25.9GOPS/mm2 area efficiency is achieved.
The metaphase II arrest in mouse oocytes is controlled through microtubule‐dependent destruction of cyclin B in the presence of CSF.

In unfertilized eggs from vertebrates, the cell cycle is arrested in metaphase of the second meiotic division (metaphase II) until fertilization or activation. Maintenance of the long‐term meiotic metaphase arrest requires mechanisms preventing the destruction of the maturation promoting factor (MPF) and the migration of the chromosomes. In frog oocytes, arrest in metaphase II (M II) is achieved by cytostatic factor (CSF) that stabilizes MPF, a heterodimer formed of cdc2 kinase and cyclin. At the metaphase/anaphase transition, a rapid proteolysis of cyclin is associated with MPF inactivation. In Drosophila, oocytes are arrested in metaphase I (M I); however, only mechanical forces generated by the chiasmata seem to prevent chromosome separation. Thus, entirely different mechanisms may be involved in the meiotic arrests in various species. We report here that in mouse oocytes a CSF‐like activity is involved in the M II arrest (as observed in hybrids composed of fragments of metaphase II‐arrested oocytes and activated mitotic mouse oocytes) and that the high activity of MPF is maintained through a continuous equilibrium between cyclin B synthesis and degradation. In addition, the presence of an intact metaphase spindle is required for cyclin B degradation. Finally, MPF activity is preferentially associated with the spindle after bisection of the oocyte. Taken together, these observations suggest that the mechanism maintaining the metaphase arrest in mouse oocytes involves an equilibrium between cyclin synthesis and degradation, probably controlled by CSF, and which is also dependent upon the three‐dimensional organization of the spindle.
Diel activity of arboreal arthropods associated with Papua New Guinean trees

The diel activity of arboreal arthropods foraging within the crowns of nine species of trees native to submontane rain forests in Papua New Guinea was studied. Data were collected over a 30-day period, using modified flight-interception traps, which are described briefly. Sampling was designed to enable segregation of material into day- and night-catches. Arthropod activity (measured by the number of individuals collected) was correlated positively with minimum air temperature. As a probable consequence, overall arthropod activity was significantly higher during day-time than night-time and night catches represented 72% of day catches. Predators, parasitoids, wood-eaters, ant workers and entomophagous arthropods were significantly more active during day than night. Few arthropod groups showed an inverse behaviour. Regression slopes comparing entomophages versus herbivores during day- and night-time were not significantly different. The data do not support the hypothesis that herbivores are particularly ac.
Quartz : Heat capacities from 340 to 1000 K and revised values for the thermodynamic properties

New heat-capacity data for quartz have been measured over the temperature interval of 340 to 1000 K by differential scanning calorimetry. The data were combined with recent heat-content and heat-capacity data to provide a significantly revised set of thermodynamic properties for a-quartz and to resolve the problem of disparate heat-content and heat-capacity dala for aand ! -quartz. The results of this study show that the values of heat capacity and/or heat content and ofthe properties derived from these values that are listed in all recent tabulations of the thermodynamic properties of a-quarlz are significantly low between about 600 and 800 K. The revised thermodynamic properties for a-quartz will most strongly affect calculations involving mineral reactions at moderate temperatures and higher pressures, such as those describing the evolution of materials in subducted plates, particularly where the data for a-quartz must be extrapolated to temperatures above 844 K for calculations involving higher pressures.
Visual Function and Quality of Life Among Patients with Giant Cell (Temporal) Arteritis

Objective To investigate patient perception of visual and systemic disability associated with giant cell arteritis (GCA) and whether the perceived disability can be correlated with visual performance measures. Methods We prospectively evaluated and compared the visual performance and quality of life survey for 20 patients with GCA after 4 to 5 weeks of corticosteroid therapy and after one year of therapy. We measured visual acuity, contrast sensitivity, and threshold perimetry and patients completed the Activities of Daily Vision Scale (ADVS) and the short-form of the Health Survey (SF-36). The results were grouped by GCA affected or unaffected eye or by better or worse eye and reported as a decimal and percent impairment for acuity, log units for contrast, mean deviation and the Advanced Glaucoma Intervention Study (AGIS) score for perimetry. The results for patients with and without visual loss were compared. Correlation analyses between ADVS categories and visual performance measures, SF-36 categories and the presence of visual loss, total corticosteroid dose, systemic symptoms, secondary hypertension or diabetes mellitus, the presence of vertebral fracture, and visual performance were performed. Results Day driving was the only ADVS category significantly reduced at baseline in patients with visual loss (62.5) compared with those without visual loss (96.3, P = 0.04). Modest to moderate correlations between ADVS categories were most frequent for percent binocular acuity impairment with day driving (r = −0.62, P = 0.017), with distance vision (r = −0.5, P = 0.02), and with glare (r = −0.59, P = 0.006); and the AGIS score of the worse eye with day driving (r = −0.66, P = 0.01), with near vision (r = −0.49, P = 0.03), and with glare (r = −0.48, P = 0.04). The baseline SF-36 scores did not correlate with the presence of vision loss at baseline or systemic complications. The ADVS and SF-36 scores were similar at one year. The total dose of corticosteroids only had a modest correlation with the one-year mental health score (r = −0.45, P = 0.05), but there was no correlation between SF-36 scores and other systemic side effects of steroid therapy. Conclusion Except for the day driving score, the ADVS did not differ between patients with and without visual loss. The SF-36 did not distinguish between patients with and without visual loss and did not reveal significant trends. The ADVS and SF-36 did not reveal significant disability in GCA patients and there were no strong correlations with any visual performance or systemic measures.
Massive uncoordinated multiway relay networks with simultaneous detections

In this paper, we consider multiway relay networks with massive number of users. In this situation a fixed transmission scheduling is difficult to apply. We propose uncoordinated communications using the concept of coded slotted ALOHA (CSA), where simultaneous transmitted signals are detected using iterative demapping (IDM) algorithm to improve the success rate probability. We allow each user to transmit the information via any random time slots (during the contention period) to the network. We show the bound of the proposed system and confirm an achievable point using practical coding. We also evaluate the bit-error-rate (BER) performance of the proposed technique via computer simulations. The results indicate that even though with the offered traffic of 1.11 packets/slot, reliable communications is achievable. It is also validated that the proposed system works very well even in relatively low signal-to-noise ratio (SNR) environments. Moreover, the packet-loss-rate (PLR) evaluation shows that the proposed technique outperforms the conventional CSA without simultaneous detection algorithm.
Sensorimotor Psychotherapy Group Therapy in the Treatment of Complex PTSD

In this article we evaluate a new modality of treatment for a very severe and chronically ill population at a National Trauma Centre. We describe the service with its current treatment options and the type of patients selected for this new intervention. PTSD is presented as a biphasic syndrome, necessitating treatment approaches that address both physiological arousal and alexithymia and numbing. Each Sensorimotor Psychotherapy session addresses a different set of symptoms sequenced in order of importance from a trauma-treatment perspective, including: autonomic arousal, implicit memory, basic techniques for regulating arousal, directing focused attention, boundaries and skills practice. We describe methodology issues, aims of the treatment and statistical results as well as qualitative aspects of the outcome. Statistically significant changes in pre-treatment scores on measures of PTSD symptoms, depression, overall health, and work and social functioning were observed. This study has important implications for stabilization phase one treatment in the management of individuals with complex trauma presentations.
Quantitative Hemodynamic Analysis of Brain Aneurysms at Different Locations

BACKGROUND AND PURPOSE: Studies have shown that the occurrence of brain aneurysms and risk of rupture vary between locations. However, the reason that aneurysms at different branches of the cerebral arteries have different clinical presentations is not clear. Because research has indicated that aneurysm hemodynamics may be one of the important factors related to aneurysm growth and rupture, our aim was to analyze and compare the flow parameters in aneurysms at different locations. MATERIALS AND METHODS: A total of 24 patient-specific aneurysm models were constructed by using 3D rotational angiographic data for the hemodynamic simulation. Previously developed computational fluid dynamics software was applied to each aneurysm to simulate the blood-flow properties. Hemodynamic data at peak pulsatile flow were recorded, and wall shear stress (WSS) and flow rate in the aneurysms and parent arteries were quantitatively compared. To validate our method, a comparison with a previously reported technique was also performed. RESULTS: WSS and flow rate in the aneurysms at the peak of the cardiac cycle were found to differ in magnitude between different locations. Multiple comparisons among locations showed higher WSS and flow rate in middle cerebral artery aneurysms and lower WSS and flow rate in basilar artery and anterior communicating artery aneurysms. CONCLUSIONS: We observed changes in hemodynamic values that may be related to aneurysm location. Further study of aneurysm locations with a large number of cases is needed to test this hypothesis.
Age-dependent changes in pituitary-gonadal relationships. 3. Changes in pituitary LH and FSH levels in the male rat.

Summary. Pituitary levels of fsh (Steelman-Pohley assay) and lh (Parlow assay) were determined in male rats of various ages. The lh level began to rise by Day 33 of life, reached a peak between Days 43 and 47, and declined in the post-puberal period. The fsh level (\g=m\g/mg and \g=m\g/pituitary/100 g body weight) began to rise very much earlier and had already reached its peak around Day 33, when testicular growth was rapid but before full spermatogenesis was established. In post-puberal rats, the fsh levels were much lower than those reached before puberty. The implication of these findings and the possibility that fsh and lh are sequentially involved in initiating spermatogenesis in the puberal rat are discussed.
An Accurate Interpolation Scheme With Derivative Term for Generating MoM Matrices in Frequency Sweeps

A new accurate impedance matrix interpolation algorithm is proposed for frequency sweeps arising in the method of moments (MoM). Its performance is optimized by specifying the choice of the internal frequency sample within a given frequency band. The modified matrix element employed in this scheme is a product of the normalized frequency and the remaining part of the impedance matrix element after factoring out the dominant phase term, where the normalized frequency means that the frequency is normalized by the highest frequency. Based on the modified matrices at three normalized frequency samples and the derivative of the modified matrix at the internal sample, the matrices over the frequency band are fast generated via interpolation. The proposed scheme requires the same storage as the Hermite scheme and 25% storage more than the improved Lagrange scheme. Numerical examples indicate that it yields more accurate matrices over the frequency band than both the Hermite scheme and the improved Lagrange scheme.
Racial segregation and disparities in health care delivery: conceptual model and empirical assessment.

OBJECTIVE This study examines two dimensions of racial segregation across hospitals, using a disease for which substantial disparities have been documented. DATA SOURCES Black (n=32,289) and white (n=244,042) patients 67 years and older admitted for acute myocardial infarction during 2004-2005 in 105 hospital markets were identified from Medicare data. Two measures of segregation were calculated: Dissimilarity (i.e., dissimilar distribution by race across hospitals), and Isolation (i.e., racial isolation within hospitals). For each measure, markets were categorized as having low, medium, or high segregation. STUDY DESIGN The relationship of hospital segregation to residential segregation and other market characteristics was evaluated. Cox proportional hazards regression was used to evaluate disparities in the use of revascularization within 90 days by segregation level. RESULTS Agreement of segregation category based on Dissimilarity and Isolation was poor (kappa=0.12), and the relationship of disparities in revascularization to segregation differed by measure. The hazard of revascularization for black relative to white patients was lowest (i.e., greatest disparity) in markets with low Dissimilarity, but it was unrelated to Isolation. CONCLUSIONS Significant racial segregation across hospitals exists in many U.S. markets, although the magnitude and relationship to disparities depends on definition. Dissimilar distribution of race across hospitals may reflect divergent cultural preferences, social norms, and patient assessments of provider cultural competence, which ultimately impact utilization.
Humoral mechanisms in the pathogenesis of postprandial hypotension in patients with essential hypertension.

OBJECTIVE To examine the role of catecholamines and insulin in the development of postprandial hypotension (PPH) in hypertensive patients. PATIENTS Forty patients with essential hypertension (25 men, 15 women, mean age 68 +/- 2 years). METHOD Blood pressure and heart rate were recorded in all subjects immediately after a 1903 kJ test meal and at 15-minute intervals for up to 1 hour after the meal. At these time points, circulating levels of norepinephrine, epinephrine, dopamine and C-peptide were measured. RESULTS Twenty-three patients (58%) had PPH. By 15 minutes norepinephrine had significantly increased in PPH-negative subjects while it rose more slowly in PPH-positive patients and peaked by 45 minutes after the meal. Norepinephrine levels in 15 minutes were lower in PPH-positive than in PPH-negative ones (159.8 +/- 9.7 vs. 212.3 +/- 21.1 pg/ml, p = 0.01). Epinephrine levels rose only in PPH-negative subjects and did not differ significantly at the different time points. However, the area under curve analysis showed significantly lower epinephrine values in PPH-positive subjects (2903 + 247 pg.min.ml-1 vs. 3710 + 284 pg.min.ml-1, p = 0.03). Dopamine increased in both groups, although it was lower in subjects with PPH during the entire study (15 minutes: 68.6 +/- 3.7 vs. 93.7 +/- 11.7 pg/ml, p = 0.02; 30 minutes: 68.8 +/- 3.7 vs. 86.1 +/- 7.7 pg/ml, p = 0.03; 45 minutes: 60.5 +/- 4.2 vs. 79.7 +/- 5.2 pg/ml, p = 0.006). The postprandial C-peptide response did not differ between patients with PPH and those without PPH. CONCLUSIONS In patients with essential hypertension, a marked decline in postprandial systolic blood pressure is associated with lower postprandial levels of norepinephrine, epinephrine and dopamine as compared to subjects without postprandial hypotension. This indicates that impaired sympatho-adrenal activation after ingestion of a meal may contribute to the development of PPH. Insulin appears not to be involved in the pathogenesis of postprandial hypotension.
