Nurses' views of patient participation in nursing care.

AIMS To explore nurses' views of patient participation in nursing care on medical wards. BACKGROUND Nurses have frequent contact with patients, highlighting their potential role in enabling patient participation. However, some nurses' actions and attitudes act as barriers, failing to achieve core requirements of patient participation. Discovering nurses' views may assist in developing strategies to encourage patient participation in hospitals. DESIGN Interpretive study. METHODS Twenty nurses were recruited from four medical wards, located in two Australian hospitals. In-depth semi-structured interviews were conducted between November 2013-March 2014 and analysed using content analysis. FINDINGS Five categories emerged from the nurses' views. The first category, acknowledging patients as partners, showed nurses respected patients as legitimate participants. In the second category, managing risk, nurses emphasized the need to monitor participation to ensure rules and patient safety were maintained. Enabling participation was the third category, which demonstrated nurses' strategies that enhanced patients' participation. The fourth category was hindering participation; encapsulating nurses' difficulty in engaging patients with certain characteristics. In the final category, realizing participation, nurses believed patients could be involved in physical activities or clinical communication. CONCLUSION Nurses have a crucial role in promoting patient participation. Through acknowledging and enabling participation, nurses may facilitate patient participation in a range of nursing activities. The nurse's role in enacting participation is complex, having to accommodate each patient's risks and characteristics, highlighting the need for good assessment skills. Education, policy and research strategies are essential to foster nurses' pivotal role in patient participation.
Prevalence of pervasive developmental disorders in the British nationwide survey of child mental health

The prevalence of pervasive developmental disorders (PDD) is not well established and needs monitoring. We investigated the prevalence of PDDs in the 1999 nationwide British survey of child and adolescent mental health. A randomized stratified sample of children (n = 12,529) aged 5-15 was generated from Child Benefit Records. Trained interviewers interviewed parents and youths aged 11 or older with a standardized diagnostic interview (Development and Well-Being Assessment) and questionnaire data (Strengths and Difficulties Questionnaire) were obtained from teachers and parents who also completed self-report measures of psychological distress. A team of experienced clinicians using all data sources achieved final diagnostic determination. A total of 10,438 (83%) interviews were conducted. There were two girls with Rett syndrome (weighted prevalence: 3.8/10,000 girls) and 27 children with other PDDs (weighted prevalence: 26.1/10,000). Compared to children with a psychiatric disorder other than PDD, social but not behavioural problems were more frequent in the PDD group. Parents of children with PDDs had higher rates of psychological distress than those from the two comparison groups. Consistent with other recent surveys, PDD rates are higher than those reported 30 years ago. The burden associated with PDDs is very high.
Schedule-induced ethanol self-administration in DBA/2J and C57BL/6J mice.

BACKGROUND The purpose of these experiments was to provide an initial investigation into ethanol self-administration elicited in the schedule-induced polydipsia (SIP) paradigm. METHODS Mature male mice were food deprived to between 80 and 85% of their baseline weight and received 20 daily 1 hr SIP test sessions in which a food pellet (20 mg) was delivered on a fixed-time 60 sec schedule. In different groups, the acquisition of drinking 5% (v/v) ethanol solution (experiment 1) or water (experiment 2) was recorded along with other behaviors that occurred in the test chambers. RESULTS Results indicated that C57BL/6J mice drank significantly more ethanol than DBA/2J mice and that C57 mice achieved blood alcohol concentrations as high as 300 mg/dl. Blood alcohol concentrations were consistently correlated with g/kg ethanol intake. The groups did not differ in consumption of water. SIP test sessions using higher concentrations of ethanol (10-20% v/v, experiment 1) or sucrose solutions (0.1-2% w/v, experiment 2) then were performed. Group differences in ethanol consumption were maintained at all ethanol concentrations. Although DBAs drank more of a low concentration of sucrose (0.1%), when expressed as g/kg, sucrose intake was equivalent in the two strains at all concentrations. Analysis of the time course of drinking clearly showed that this behavior was adjunctive in nature. CONCLUSION These results demonstrate the effectiveness of this procedure in inducing ethanol self-administration and its utility for investigating the genetic bases of vulnerability toward excessive ethanol consumption.
Analysis of the misalignment in a capacitively coupled contactless power transfer system

This paper proposes to analyze the influence of the displacement of the capacitor plates on the performances of an electrical coupled contactless power transfer system. The armatures are of circular form and the values of their radii are different. Some formulae are obtained and based on them graphical representations are made in order to analyze the nonlinear behavior. Then these variable values of the coupling capacitances are considered in the analysis of the power transfer system circuit. The influence of the misalignment on the system efficiency is commented.
Conservative Treatment of Retropharyngeal and Parapharyngeal Abscess in Children

Parapharyngeal and retropharyngeal infections, which can potentially cause life-threatening complications, could be treated conservatively with no need for surgical drainage. A retrospective analysis of all patients diagnosed with retropharyngeal and parapharyngeal infections was performed. Information regarding age, sex, presenting symptoms, physical examination, laboratory and imaging evaluations, management, duration of hospital stay, and complications were reviewed. Seven children were identified, 4 with retropharyngeal abscess and 3 with parapharyngeal abscess. All but 1 patient were under 7 years old, and all were treated with intravenous amoxicilin/clavulanic acid and corticosteroids. Torticollis and fever were present in all the patients. The mean length of hospital stay was 7 days. There were no complications associated. We demonstrate that retropharyngeal and parapharyngeal abscesses can be treated medically, reserving the surgical drainage for complicated cases. Treatment with intravenous antibiotics and corticosteroids is a safe option, reducing the durations of symptoms and the length of hospital stay.
Wear Fast, Die Young: More Worn Teeth and Shorter Lives in Iberian Compared to Scottish Red Deer

Teeth in Cervidae are permanent structures that are not replaceable or repairable; consequently their rate of wear, due to the grinding effect of food and dental attrition, affects their duration and can determine an animal's lifespan. Tooth wear is also a useful indicator of accumulative life energy investment in intake and mastication and their interactions with diet. Little is known regarding how natural and sexual selection operate on dental structures within a species in contrasting environments and how these relate to life history traits to explain differences in population rates of tooth wear and longevity. We hypothesised that populations under harsh environmental conditions should be selected for more hypsodont teeth while sexual selection may maintain similar sex differences within different populations. We investigated the patterns of tooth wear in males and females of Iberian red deer (Cervus elaphus hispanicus) in Southern Spain and Scottish red deer (C. e. scoticus) across Scotland, that occur in very different environments, using 10343 samples from legal hunting activities. We found higher rates of both incisor and molar wear in the Spanish compared to Scottish populations. However, Scottish red deer had larger incisors at emergence than Iberian red deer, whilst molars emerged at a similar size in both populations and sexes. Iberian and Scottish males had earlier tooth depletion than females, in support of a similar sexual selection process in both populations. However, whilst average lifespan for Iberian males was 4 years shorter than that for Iberian females and Scottish males, Scottish males only showed a reduction of 1 year in average lifespan with respect to Scottish females. More worn molars were associated with larger mandibles in both populations, suggesting that higher intake and/or greater investment in food comminution may have favoured increased body growth, before later loss of tooth efficiency due to severe wear. These results illustrate how independent selection in both subspecies, that diverged 11,700 years BP, has resulted in the evolution of different longevity, although sexual selection has maintained a similar pattern of relative sex differences in tooth depletion. This study opens interesting questions on optimal allocation in life history trade-offs and the independent evolution of allopatric populations.
Whole cell & culture filtrate proteins from prevalent genotypes of Mycobacterium tuberculosis provoke better antibody & T cell response than laboratory strain H37Rv

Background & objectives: The immune responses to different antigens of Mycobacterium tuberculosis H37Rv vary from patient to patient with tuberculosis (TB). Therefore, significant difference might be documented between the H37Rv with long histories of passages and recent clinical isolates of M. tuberculosis. In the present study, immune response of TB patients and healthy controls against 39 clinical M. tuberculosis isolates was correlated with laboratory strain H37Rv. Methods: The antibody response was studied coating whole cell extracts and culture filtrate proteins of M. tuberculosis isolates and laboratory strain H37Rv by enzyme linked immunosorbent assay (ELISA). Lymphoproliferation was studied by incorporation of tritiated thymidine and cytokines (IFN-γ and IL-4) by using commercially available kits. Results: Sero-reactivity to whole cell extract (WCE) of 11 clinical isolates was higher with pooled serum and individual's serum from tuberculosis patients showed significant reactivity (P<0.05) to ten of these isolates using ELISA. Of the WCE of 39 clinical isolates, 10 were found to be potent inducer of lymphoproliferation as well as cytokine secretion (P<0.05) in peripheral blood mononuclear cells from PPD+ healthy controls. Six culture filtrate proteins (CFPs) from these selected clinical isolates were also better inducers of antibody and T-cell response. Interpretation & conclusion: Overall, our results revealed that the clinical isolates belonging to prevalent genotypes; CAS1_Del (ST-26), East African-Indian (ST-11) and Beijing family (ST-1) induced better antibody and T cell responses compared to H37Rv laboratory strain. Further studies need to be done to purify and identify the dominant protein (s) using whole cell extract and culture filtrates from these immunologically relevant clinical M. tuberculosis isolates, which will be worthwhile to find out pathogenic factors, potential diagnostic markers and protective molecules for tuberculosis.
Cooperation of Adipocytes and Endothelial Cells Required for Catecholamine Stimulation of PGI2 Production by Rat Adipose Tissue

Disturbances of prostaglandin I2 (PGI2, prostacyclin) production by adipose tissue contribute to the pathogenesis of diabetic ketoacidosis and may contribute to the pathogenesis of hypertension and vascular disease. We studied the cellular basis of PGI2 production in adipose tissue, measured as release of 6-keto-PGF1α in response to epinephrine. Adipocytes did not produce PGI2 when nonfat cells were removed by repeated washing. The nonadipocyte cellular constituents of adipose tissue (nonfat cells) did not produce PGI2 in the absence of adipocytes. Both adipocytes and nonfat cells were required for PGI2 production in response to epinephrine. Adipocytes pretreated with 0.2 mM aspirin to inhibit PGH synthase nevertheless promoted PGI2 production when mixed with nonfat cells. Nonfat cells preincubated with aspirin did not produce PGI2 when mixed with adipocytes. The nonfat cells converted arachidonic acid to PGI2 but adipocytes did not. Epinephrine stimulated lipolysis and PGI2 production in a dose-dependent parallel manner, but the responses were distinct above 10−6 M. Characterization of the nonfat cells by fractionation on a Percoli density gradient followed by measurement of angiotensincon vert ing enzyme activity and 6-keto-PGF1α production indicated that the nonfat cells were predominantly vascular endothelial cells. We conclude that catecholamine-stimulated PGI2 production in adipose tissue results from the cooperation of adipocytes and vascular endothelial cells. The adipocytes provide arachidonic acid, which is converted to PGI2 by the vascular endothelial cells. Because adipose tissue is located near blood vessels throughout the body, adipocytes may be an important source of arachidonic acid for vascular endothelial cells in various circumstances in health and disease. Our findings raise the possibility that adipocytes may, under some circumstances, release arachidonic acid into the systemic circulation where it is used by vascular endothelial cells throughout the body to produce PGI2 and other eicosanoids.
Treatment‐related stresses and depression in couples undergoing assisted reproductive treatment by IVF or ICSI

Summary. The purposes of the study were to compare treatment‐related stresses of couples undergoing IVF or ICSI treatment (ejaculated, epididymal or testicular spermatozoa) and to identify sex differences and risk factors for depression. A one‐year cohort of couples was retrospectively sent questionnaires on infertility and treatment‐related distress and depression (Depression Scale, D‐S). Two hundred and eighty‐one women and 281 men (61% of those eligible) were included. As determined by analysis of the medical charts, successful couples were more likely to participate. Treatment‐related distress was generally higher for women than for men. Treatment by ICSI carried additional burdens for the men: they reported a greater subjective responsibility for the infertility, impact of childlessness on daily life, treatment‐related stresses (particularly for MESA/TESE) and time demands. Even when clinical differences between treatments (e.g. age, previous treatments) were controlled statistically, depression scores did not differ. Independent of the treatment, women were significantly more depressed than their agematched female controls from the general population and their husbands. The men only reported marginally elevated depression scores compared to their controls. Meaningful characteristics were identified that could guide clinicians to give psychological support to those couples at risk for depression, e.g. an unsuccessful treatment outcome, repeated treatment cycles, a low socioeconomic status, foreign nationality, or, for women, a lack of partner support.
Inhibition of voluntary activity by thalamic stimulation in humans: Relevance for the control of tremor

The motor effects of stimuli delivered through four‐channel, quadripolar macroelectrodes chronically implanted in the ventrolateral thalamus were studied in 20 awake cooperating human subjects. Single stimuli could inhibit voluntary contraction of the contralateral first dorsal interosseous muscle (FDI) for up to 200 ms. The inhibition was often followed by a rebound facilitation or by oscillatory activity. This inhibition appeared to arise from the ventrolateral thalamus and could not be obtained in other patients by stimulation of the periventricular grey matter (PVG), the globus pallidus internus (GPI), or the subthalamic nucleus (STN). The neural elements activated by the stimulus had a short chronaxie and a short refractory period, implying that they were large‐diameter axons. Similar effects were obtained from each of the four electrodes in the row, suggesting that this fiber system lay parallel rather than perpendicular to the implanted macroelectrode. The inhibition resulting from a single stimulus was diminished by a prior stimulus or train of stimuli. A continuous train of stimuli produced inhibition for only the first 200 ms. We propose that the thalamic stimulus activates a neural network which includes thalamic relay cells and neurons of the thalamic reticular nucleus and that the inhibition of thalamic relay cells habituates with repeated stimuli. It has been suggested that parkinsonian rest tremor results from synchronization of the oscillatory activity of this network. If this is the case, continuous thalamic stimulation might disrupt this oscillation by diminishing the inhibitory phase.
Post Exposure Prophylaxis for Occupational Exposures to HIV and Hepatitis B: Our Experience of Thirteen Years at a Rural Based Tertiary Care Teaching Hospital of Western India.

INTRODUCTION Health Care Workers (HCWs) are at risk of occupational transmission of HIV, Hepatitis B and Hepatitis C, which can be minimized by following guidelines for standard precautions as well as taking Post Exposure Prophylaxis (PEP) measures. There are limited studies from India documenting details of PEP for HIV and Hepatitis B. AIM We aimed to study the efficacy, tolerance, details of PEP regimens used among HCWs exposed to HIV and Hepatitis B as well as vaccination status and (Anti-Hepatitis B Surface Antigen) anti-HBS Antibody Titre Level Among HCWs exposed Hepatitis B. STUDY DESIGN This retrospective observational study was done at a rural based tertiary care teaching centre of Western India. MATERIALS AND METHODS Hospital Infection Control Committee of our institute was maintaining a record of all reported incidences of HIV and Hepatitis B positive exposures since 2003. We analysed reported incidences of exposures to HIV and Hepatitis B positive source occurred during the period of January 2003 to December 2015. RESULTS Of the total 96 exposures, 48 were to HIV and 48 were to Hepatitis B. Of the 48 exposures to HIV, PEP was warranted in 39. Of 39 exposures, only 14 (35.9%) received PEP within two hours. Basic regimen was used in 22 and expanded in 17 exposures. Only 12 (31.6%) reported side effects to PEP. Zidovudine based regimen was less well tolerated. All side effects were reported by female HCWs only. Of the 48 exposed to Hepatitis B, 33 (68.6%) were completely vaccinated. Out of 33, titre result was not available for eight. Three (12.0%) of remaining 25 were having low titre (<10mIU/ml) of anti-HBS antibody. Five of six with incomplete vaccination status demonstrated anti HBS antibody titre > 100mIU/ml. Of the 48, in 17 (35.4%) incidences no action was required; 23 (47.9%) were managed with booster dose of Hepatitis B vaccine and eight (16.7%) with Hepatitis B immunoglobulin. No cases of sero-conversion was reported either for HIV or Hepatitis B from available data. CONCLUSION Inspite of high incidences of exposures to HIV or Hepatitis B positive source, good efficacy of PEP was observed with no sero-conversion. PEP for HIV was well tolerated; female HCWs were less tolerant. Study emphasized the need for creating awareness about timely reporting of incidence, achieving maximum vaccination against Hepatitis B for all HCWs and need for anti-HBS antibody titre.
Skull ontogeny: developmental patterns of fishes conserved across major tetrapod clades

SUMMARY In vertebrates, the ontogeny of the bony skull forms a particularly complex part of embryonic development. Although this area used to be restricted to neontology, recent discoveries of fossil ontogenies provide an additional source of data. One of the most detailed ossification sequences is known from Permo‐Carboniferous amphibians, the branchiosaurids. These temnospondyls form a near‐perfect link between the piscine osteichthyans and the various clades of extant tetrapods, retaining a full complement of dermal bones in the skull. For the first time, the broader evolutionary significance of these event sequences is analyzed, focusing on the identification of sequence heterochronies. A set of 120 event pairs was analyzed by event pair cracking, which helped identify active movers. A cladistic analysis of the event pair data was also carried out, highlighting some shared patterns between widely divergent clades of tetrapods. The analyses revealed an unexpected degree of similarity between the widely divergent taxa. Most interesting is the apparently modular composition of the cranial sequence: five clusters of bones were discovered in each of which the elements form in the same time window: (1) jaw bones, (2) marginal palatal elements, (3) circumorbital bones, (4) skull roof elements, and (5) neurocranial ossifications. In the studied taxa, these “modules” have in most cases been shifted fore and back on the trajectory relative to the Amia sequence, but did not disintegrate. Such “modules” might indicate a high degree of evolutionary limitation (constraint).
Cervical spine motion during football equipment-removal protocols: a challenge to the all-or-nothing endeavor.

CONTEXT The National Athletic Trainers' Association position statement on acute management of the cervical spine-injured athlete recommended the all-or-nothing endeavor, which involves removing or not removing both helmet and shoulder pads, from equipment-laden American football and ice hockey athletes. However, in supporting research, investigators have not considered alternative protocols. OBJECTIVE To measure cervical spine movement (head relative to sternum) produced when certified athletic trainers (ATs) use the all-or-nothing endeavor and to compare these findings with the movement produced using an alternative pack-and-fill protocol, which involves packing the area under and around the cervical neck and head with rolled towels. DESIGN Crossover study. SETTING Movement analysis laboratory. PATIENTS OR OTHER PARTICIPANTS Eight male collegiate football players (age = 21.4 ± 1.4 years; height = 1.87 ± 0.02 m; mass = 103.6 ± 12.5 kg). INTERVENTION(S) Four ATs removed equipment under 4 conditions: removal of helmet only followed by placing the head on the ground (H), removal of the helmet only followed by pack-and-fill (HP), removal of the helmet and shoulder pads followed by placing the head on the ground (HS), and removal of the helmet and shoulder pads followed by pack-and-fill (HSP). Motion capture was used to track the movement of the head with respect to the sternum during equipment removal. MAIN OUTCOME MEASURE(S) We measured head movement relative to sternum movement (translations and rotations). We used 4 × 4 analyses of variance with repeated measures to compare discrete motion variables (changes in position and total excursions) among protocols and ATs. RESULTS Protocol HP resulted in a 0.1 ± 0.6 cm rise in head position compared with a 1.4 ± 0.3 cm drop with protocol HS (P < .001). Protocol HP produced 4.9° less total angular excursion (P < .001) and 2.1 cm less total vertical excursion (P < .001) than protocol HS. CONCLUSIONS The pack-and-fill protocol was more effective than shoulder pad removal in minimizing cervical spine movement throughout the equipment-removal process. This study provides evidence for including the pack-and-fill protocol in future treatment recommendations when helmet removal is necessary for on-field care.
