RESUMO

BACKGROUND: Colder temperature exposure is a known trigger for pediatric asthma exacerbation. The induction of oxidative stress is a known pathophysiologic pathway for asthma exacerbation. However, the role of oxidative stress in linking colder temperature exposure and worsened pediatric asthma symptoms is poorly understood. METHODS: In a panel study involving 43 children with asthma, aged 5-13 years old, each child was visited 4 times with a 2-week interval. At each visit, nasal fluid, urine, and saliva samples were obtained and measured for biomarkers of oxidative stress in the nasal cavity (nasal malondialdehyde [MDA]), the circulatory system (urinary MDA), and the oral cavity (salivary MDA). Childhood Asthma-Control Test (CACT) was used to assess asthma symptoms. RESULTS: When ambient daily-average temperature ranged from 7 to 18 °C, a 2 °C decrement in personal temperature exposures were significantly associated with higher nasal MDA and urinary MDA concentrations by 47-77% and 6-14%, respectively. We estimated that, of the decrease in child-reported CACT scores (indicating worsened asthma symptoms and asthma control) associated with colder temperature exposure, 14-57% were mediated by nasal MDA. CONCLUSION: These results suggest a plausible pathway that colder temperature exposure worsens pediatric asthma symptoms partly via inducing nasal oxidative stress. IMPACT: The role of oxidative stress in linking colder temperature exposure and worsened asthma symptoms is still poorly understood. Lower temperature exposure in a colder season was associated with higher nasal and systemic oxidative stress in children with asthma. Nasal MDA, a biomarker of nasal oxidative stress, mediated the associations between colder temperature exposures and pediatric asthma symptoms. The results firstly suggest a plausible pathway that colder temperature exposure worsens pediatric asthma symptoms partly via inducing oxidative stress in the nasal cavity.

RESUMO

Exposure to fine particulate matter (PM2.5) and ozone (O3) may lead to inflammation and oxidative damage in the oral cavity, which is hypothesized to contribute to the worsening of airway inflammation and asthma symptoms. In this panel study of 43 asthmatic children aged 5-13 years old, each child had 4 clinic visits with a 2-week interval between two consecutive visits. At each visit, saliva samples were collected and subsequently analyzed for interleukin 6 (IL-6) and eosinophil cationic protein (ECP) as biomarkers of inflammation and malondialdehyde (MDA) as a biomarker of oxidative stress in the oral cavity. At each visit, children were measured for fractional exhaled nitric oxide (FeNO) as a marker of pulmonary inflammation. Asthma symptoms of these children were measured using the Childhood Asthma Control Test (C-ACT). We found that an interquartile range (IQR) increase in 24-h average personal exposure to PM2.5 measured 1 and 2 days prior was associated with increased salivary IL-6 concentration by 3.0% (95%CI: 0.2%-6.0%) and 4.2% (0.7%-8.0%), respectively. However, we did not find a clear association between personal O3 exposure and any of the salivary biomarkers, except for a negative association between salivary MDA and O3 exposure measured 1 day prior. An IQR increase in salivary IL-6 concentration was associated with significantly increased FeNO by 28.8% (4.3%-53.4%). In addition, we found that increasing salivary IL-6 concentrations were associated with decreased individual and total C-ACT scores, indicating the worsening of asthma symptoms. We estimated that 13.2%-22.2% of the associations of PM2.5 exposure measured 1 day prior with FeNO and C-ACT scores were mediated by salivary IL-6. These findings suggest that the induction of inflammation in the oral cavity may have played a role in linking air pollution exposure with the worsening of airway inflammation and asthma symptoms.

RESUMO

BACKGROUND: It is generally accepted that headshake nystagmus (HSN) is generated from an asymmetrical peripheral vestibular input and a correlation exists between HSN and canal paresis. There have been limited reports, however, how HSN correlates with the more recently introduced tests of vestibular function. AIMS/OBJECTIVES: To evaluate the correlation between HSN and unilateral weakness on caloric testing, high-frequency vestibulo-ocular reflex (VOR) function on video head impulse testing (VHIT) and otolith function determined by vestibular evoked myogenic potentials (VEMPs). METHODS: A retrospective study of all patients who underwent complete vestibular function testing at our tertiary referral center from 2016 to 2019 was performed. Demographic data, clinical diagnosis (where available), the results of video-nystagmography, vHIT, and VEMPs were evaluated. RESULTS: Of the 1499 patients in the study period, 101 (6.7%) had HSN. Vestibular test abnormalities were more common in patients with HSN. The sensitivity of HSN for underlying pathology was low in comparison with vestibular testing. However, HSN demonstrated a high specificity. CONCLUSIONS AND SIGNIFICANCE: HSN generation is likely more complex than caloric-induced nystagmus, probably due to additional variables within the vestibular system. HSN may provide clinicians with additional information concerning high-frequency VOR function involving lateral semicircular and otolith dysfunction.

RESUMO

Fine particulate matter (PM2.5) with a higher oxidative potential has been thought to be more detrimental to pulmonary health. We aim to investigate the associations between personal exposure to PM2.5 oxidative potential and pulmonary outcomes in asthmatic children. We measured each of the 43 asthmatic children 4 times for airway mechanics, lung function, airway inflammation, and asthma symptom scores. Coupling measured indoor and outdoor concentrations of PM2.5 mass, constituents, and oxidative potential with individual time-activity data, we calculated 24 h average personal exposures 0-3 days prior to a health outcome measurement. We found that increases in daily personal exposure to PM2.5 oxidative potential were significantly associated with increased small, large, and total airway resistance, increased airway impedance, decreased lung function, and worsened scores of individual asthma symptoms and the total symptom score. Among the PM2.5 constituents, organic matters largely of indoor origin contributed the greatest to PM2.5 oxidative potential. Given that the variability in PM2.5 oxidative potential was a stronger driver than PM2.5 mass for the variability in the respiratory health outcomes, it is suggested to reduce PM2.5 oxidative potential, particularly by reducing the organic matter constituent of indoor PM2.5, as a targeted source control strategy in asthma management.

RESUMO

OBJECTIVES: Several studies have reported an association between benign paroxysmal positional vertigo (BPPV) and bone mineral density or serum vitamin D levels. The aim of this review is to provide further clarification regarding the relationship between BPPV and calcium metabolism. DESIGN: PubMed and MEDLINE databases were systematically reviewed to identify all English language papers regarding the relationship between BPPV and the following terms: osteoporosis, osteopenia, bone mineral density, serum vitamin D levels, and bone metabolism. RESULTS: Of the 456 identified records, 28 studies were eligible for this review. Most were retrospective studies with inherent limitations and often conflicting results. While the literature is not conclusive, osteoporosis in patients of at least 50 years old appears to have an association with BPPV. Similarly, an association was observed between recurrent BPPV and vitamin D deficiency. CONCLUSION: There is only weak evidence to support the relationship between BPPV and osteoporosis or low serum 25-hydroxyvitamin D levels. Further prospective studies with more robust methodologies are needed to clarify the association between BPPV and disorders of bone metabolism.

RESUMO

Portable air cleaners are increasingly used in polluted areas in an attempt to reduce human exposure; however, there has been limited work characterizing their effectiveness at reducing exposure. With this in mind, we recruited forty-three children with asthma from suburban Shanghai and deployed air cleaners (with HEPA and activated carbon filters) in their bedrooms. During both 2-week filtration and non-filtration periods, low-cost PM2.5 and O3 air monitors were used to measure pollutants indoors, outdoors, and for personal exposure. Indoor PM2.5 concentrations were reduced substantially with the use of air cleaners, from 34 ± 17 to 10 ± 8 µg/m3 , with roughly 80% of indoor PM2.5 estimated to come from outdoor sources. Personal exposure to PM2.5 was reduced from 40 ± 17 to 25 ± 14 µg/m3 . The more modest reductions in personal exposure and high contribution of outdoor PM2.5 to indoor concentrations highlight the need to reduce outdoor PM2.5 and/or to clean indoor air in multiple locations. Indoor O3 concentrations were generally low (mean = 8±4 ppb), and no significant difference was seen by filtration status. The concentrations of pollutants and the air cleaner effectiveness were highly variable over time and across homes, highlighting the usefulness of real-time air monitors for understanding individual exposure reduction strategies.

RESUMO

AIM: To illustrate the value of Checkland's 'Soft Systems' approach to explore and analyse the interaction of human and organisational factors that affect service delivery and patient experience in one specialist epilepsy service. BACKGROUND: Checkland's approach is underutilized in relation to health service improvement. One epilepsy service in Ireland is used as an example to illustrate the value of his approach to improve service delivery, particularly when what needs to change is not clear. METHOD: Checkland's 'Soft Systems' seven-stage approach was used collaboratively to explore patients' and clinicians' experience of service delivery and how to improve it. RESULTS: The research identified the practice of empowerment affected the quality of the service experience. Checkland's concept of a human activity system was particularly pertinent in identifying this issue and providing a 'map' for change. CONCLUSION: Wider inferences for the use of Checkland's approach by nurse managers are discussed, as is the value of using Checkland's approach to improve services. IMPLICATIONS FOR NURSING MANAGEMENT: Checkland's 'Soft Systems' is an underutilized approach in health care that could be used by managers to initiate and embed change within a health care service.

RESUMO

Fine particulate matter (PM2.5) and ozone (O3) may exert oxidative damage in the nose, which is hypothesized to be associated with worsened asthma symptoms. This study, hence, is to explore whether an oxidative stress biomarker, malondialdehyde (MDA) in the nasal fluid, has the potential to aid personalized asthma control. In a panel study of 43 asthmatic children, 5-13 years old, each child was measured 4 times with a 2-week interval between consecutive clinic visits. At each visit, nasal fluid and urine samples were collected, and fractional exhaled nitric oxide (FeNO) was measured as a biomarker of pulmonary inflammation. In addition to nasal MDA, urinary MDA and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were measured as biomarkers of systemic oxidative stress. We also assessed asthma symptoms using the Childhood Asthma-Control Test (C-ACT). We found that interquartile range (IQR) increases in 24 h average personal PM2.5 exposure (22.2-33.5 µg/m3), estimated 0 to 5 days prior to a clinic visit, were associated with increased nasal MDA concentrations by 38.6-54.9%. Similarly, IQR increases in 24 h average personal O3 exposure (7.7-8.2 ppb) estimated 2 to 4 days prior were associated with increased nasal MDA by 22.1-69.4%. Only increased PM2.5 exposure was associated with increased FeNO. Increased nasal MDA concentration was associated with decreased total and individual C-ACT scores, indicating worsening of asthma symptoms. However, no significant associations were observed between urinary MDA or 8-OHdG and C-ACT scores. The results confirm that oxidative stress plays an important role in linking air pollution exposure and adverse respiratory health effects. These findings support that MDA in the nasal fluid may serve as a useful biomarker for monitoring asthma status, especially in relation to PM2.5 and O3 exposures, two known risk factors of asthma exacerbation.

RESUMO

Objective: To investigate the effect of Huperzine A on memory and learning in individuals with moderate-severe traumatic brain injury (TBI).Design: Randomized, double-blind, placebo-controlled Phase II clinical trial.Methods: Subjects were randomly assigned to receive Huperzine A or placebo for 12 weeks and were assessed during in-person visits at screening/baseline, and 6, 12, 24, and 52 weeks post-injury. Changes in memory and learning scores on the California Verbal Learning Test - 2nd Edition (CVLT-II) from baseline to week 12 were assessed using permutation tests and regression analyses.Results: There was no difference between the Huperzine A and placebo groups in memory performance after 12 weeks of treatment. In the placebo group, significant improvements were noted in learning and memory scores. Both groups showed clinically important improvements in depression on the Beck Depression Index.Conclusions: The clinically important improvements in cognitive and emotional outcomes observed in both the placebo and active treatment arms of this clinical trial of Huperzine A are best understood in the context of a placebo effect. Future trials involving patients with moderate-severe TBI in the subacute to chronic phases of recovery should be designed to account for placebo effects as failure to do so may lead to spurious conclusions.

RESUMO

PURPOSE: To report our long-term results in surgical management of invasive intralabyrinthine cholesteatoma. MATERIAL AND METHODS: The study is a case series in a tertiary referral center. Retrospective chart review of all mastoid operations performed for chronic ear disease between 1994 and 2019 at University Health Network, Toronto. The type of surgery, intraoperative findings, hearing outcome, recurrence of disease and the need for revision surgery were evaluated. RESULTS: 10 cases of extensive petrous bone cholesteatoma medial to the otic capsule were identified in 616 mastoid surgeries. All but one patient with extensive petrous bone cholesteatoma who underwent an exteriorizing procedure to preserve cochlear function failed the first surgery. A second procedure was needed in all cases due to complications which included facial palsy, recurrent cholesteatoma or internal auditory canal (IAC) abscess. Hearing was not preserved in any patient. In contrast, 57 ears with cholesteatomatous labyrinthine fistula lateral to the otic capsule had matrix exteriorized and had very good long-term results. CONCLUSION: We were rarely able to preserve hearing in massive petrous bone cholesteatoma. There should be no hesitation to remove the otic capsule to exteriorize diseases even under circumstances where residual cochlear and vestibular function is present if required to provide a safe ear.

RESUMO

AIM: To review the evidence on the effects/impact of electronic nursing documentation interventions on promoting or improving quality care and/or patient safety in acute hospital settings. BACKGROUND: Electronic documentation has been recommended to improve quality care and patient safety. With the gradual move from paper-based to electronic nursing documentation internationally, there is a need to identify interventions that can effectively improve quality care and patient safety. EVALUATION: We conducted a systematic review on the effectiveness of electronic nursing documentation interventions on promoting or improving quality care and/or patient safety in acute hospital settings. KEY ISSUES: Six articles reporting on six individual studies met all eligibility criteria. They were uncontrolled pre/post intervention studies reporting positive impacts on at least one or more outcomes. Most outcomes related to documentation practice and documentation of content. CONCLUSION: Some evidence from our review indicates that implementing electronic nursing documentation in acute hospital settings is time saving, reduces rates of documentation errors, falls and infections. IMPLICATIONS FOR NURSING MANAGEMENT: A planned approach from management over time to allow nurses adapt to new electronic systems of documentation would seem a good investment in terms of efficiency of work time, possibly resulting in more time for clinical care.

RESUMO

PURPOSE: Codeine containing medicines can carry a number of health risks associated with the increase in reported misuse and dependence, however they are still readily available over the counter (OTC) in many countries. The aim of this novel study was to report on the results of a survey of customers purchasing OTC codeine containing medicinal products at pharmacies in Ireland, South Africa and England; exploring use, sources of knowledge and perception of risks. METHODS: The study design was an exploratory cross sectional survey. It involved a customer self-administered questionnaire at the point of purchase (n=1230).  Relationships between categorical variables were analysed using Pearson chi-square for bivariate analysis. Continuous scale variables were analysed using one way analysis of variance. RESULTS: In Ireland 6% stated they purchased codeine containing products weekly, in South Africa 13% and in England 16%. In Ireland and England women are more likely to view codeine containing products as harmful. In England older adults are more likely to perceive codeine containing products as harmful. A higher proportion of customers in South Africa opposed restricting codeine containing products to prescription only when compared with people in Ireland and England. CONCLUSIONS: Codeine containing products are widely purchased and used in all three jurisdictions. Whilst the majority of customers appear to have some awareness and knowledge of risks, it does not materially impact on their purchasing behaviour with a substantial minority purchasing/using such products on a weekly basis. This regularity of purchase whilst indicative of the popularity of such products, may also be a potential indicator of misuse. Future research is needed in relation to cultural and gendered differences and targeted information giving and harm reduction initiatives for safe usage of these medicinal products.

RESUMO

PURPOSE: The purpose of this paper is to review the literature as this relates to theoretical perspectives of adherence to web-based interventions, drawing upon empirical evidence from the fields of psychology, business, information technology and health care. METHODS: A scoping review of the literature utilising principles outlined by Arksey and O'Malley was undertaken. RESULTS: Several relevant theoretical perspectives have emerged, eight of which are charted and discussed in this review. These are the Internet Intervention Model, Persuasive Systems Design, the 'PERMA' framework, the Support Accountability Model, the Model of User Engagement, the Technology Acceptance Model, the Unified Theory of Acceptance and Use of IT and the Conceptual Model of User Engagement. CONCLUSIONS: The findings of the review indicate that an interdisciplinary approach, incorporating a range of technological, environmental and individual factors, may be needed in order to comprehensively explain user adherence to web-based interventions.

RESUMO

The primary motor cortex (M1) presents a somatotopic organization of body parts, but with overlap between muscle/movement representations. This distinct but overlapping M1 organization is believed to be important for individuated control and movement coordination, respectively. Discrete peaks of greater excitability observed within M1 might underpin organization of cortical motor control. This study aimed to examine interactions between M1 representations of synergist and antagonist forearm muscles, compare regions of greater excitability during different functional tasks, and compare characteristics of M1 representation recorded using surface and fine-wire (fw ) electrodes. Transcranial magnetic stimulation (TMS) was applied over M1 for mapping the representation of 4 forearm muscles (extensor carpi radialis brevis [ECRB], extensor digitorum communis, flexor carpi radialis, and flexor digitorum superficialis) during three tasks: rest, grip, and wrist extension in 14 participants. There are three main findings. First, discrete areas of peak excitability within the M1 representation of ECRBfw were identified during grip and wrist extension suggesting that different M1 areas are involved in different motor functions. Second, M1 representations of synergist muscles presented with greater overlap of M1 representations than muscles with mainly antagonist actions, which suggests a role in muscle coordination. Third, as larger normalized map volume and overlap were observed using surface than fine-wire electrodes, data suggest that cross-talk from adjacent muscles compromised interpretation of recordings made with surface electrodes in response to TMS. These results provide a novel understanding of the spatial organization of M1 with evidence of "functional somatotopy." This has important implications for cortical control of movement.

RESUMO

AIMS AND OBJECTIVES: To explore paediatric nurses' views of caring for infants who have suffered nonaccidental injury. BACKGROUND: Children less than two years of age are at greater risk of serious abuse than those in any other age group. An infant's physical and mental immaturity makes them especially vulnerable. Abuse in this age group is often caused by a parent who does not report the abuse. The experience of caring for abused children is recognised as being both personally and professionally challenging. However, despite the increased risk of serious or fatal injury, caring for these infants who have suffered abuse is relatively unexplored. DESIGN: A qualitative research design using purposive sampling was adopted. The setting for this research was a paediatric unit in Ireland. METHOD: Semi-structured interviews were conducted with 10 paediatric nurses and data were analysed using the framework approach. RESULTS: Paediatric nurses' views of caring for infants who have suffered a nonaccidental injury were established under four main themes: (1) 'Personal impact', (2) 'Professional roles', (3) 'Nurse-client relationship' and (4) 'Resources'. CONCLUSION: Findings highlighted that the experience for the nurse is complex. Personal emotions are evoked and the experience influenced reflection on their own lives. Communication with the parents of the infant is often difficult. Professional relationships were sometimes hindered by poor sharing of information. However, nurses strived to maintain their professionalism and to provide nursing care for the infant and their parents that was holistic. Paediatric nurses relied heavily on each other for support and their nursing experience was a valuable resource for managing nonaccidental injuries. RELEVANCE TO CLINICAL PRACTICE: The general consensus was that a nurse could never fully be prepared to care for an infant who had suffered a nonaccidental injury. However, recommendations for future practice and education are identified and include frequent and practical education sessions.

RESUMO

Misuse of codeine-containing medicines is an emerging global public health concern. The majority of research has been conducted in developed countries (European Members States, Australia, the United States). This study aimed to gain an understanding of unique individual and collective experiences of trajectories of codeine misuse and dependence in South Africa. In-depth interviews were conducted with a purposive sample of adult codeine misusers and dependents ( n = 25). Narratives were analyzed using the empirical phenomenological psychological five-step method. Nine themes with 63 categories emerged, with two additional high levels of abstraction. Findings are illustrated: participant profile and product preferences, motives for use, transitioning to misuse and dependence, pharmacy purchasing and alternative sourcing routes, effects and withdrawal experiences, help-seeking and treatment experiences, and strategies for prevention. The study underscores the need for continued support for enhanced patient awareness of risk of habit forming use and related health consequences and professional pharmacovigilance.

RESUMO

BACKGROUND: Misuse of codeine-containing medicines is an emerging public health issue. AIMS: We present the application of Liese and Franz's (1996) cognitive developmental model of substance abuse to the trajectory from legitimate codeine use for pain, towards that of therapeutic and other forms of misuse, and physical and psychological dependence. It illustrates a cognitive behavioural analysis of the experiences of codeine misusers - which 'surfaces' the specific beliefs, thoughts, emotions and behaviours of this group of hidden codeine dependent individuals, who are distinct and unique from other opioid-dependent cohorts. METHOD: In-depth one-to-one interviews with codeine misusers and dependent individuals in Ireland (n = 21) and South Africa (n = 25) are analysed and applied to Liese and Franz's (1996) cognitive developmental model of substance abuse. RESULTS: Misuse and dependence pathways are maintained by the interplay between physiological determinants relating to pain, withdrawal and tolerance, and psychological influences such as therapeutic need, pre-empting of anticipated physical pain, pleasure from the dreamy sedative opiate effect of codeine and relief of emotional distress. Progression towards habitual use and misuse for therapeutic and intoxication purposes appears to be mediated by external environmental triggers pertaining to availability, internal meta-cognitions around physical pain and emotional distress, and increasing importance of codeine in the life of the user. CONCLUSION: The concept mapping of codeine misuse and dependence presented here could provide psychological therapists working with individuals experiencing problems with codeine, misusing codeine and those with iatrogenic dependence, with an enhanced understanding of the key concepts involved in misuse and recovery pathways.

RESUMO

Empowerment is now seen as an integral component of holistic practice and service design in healthcare, particularly as it relates to the improvement of quality of life for people with epilepsy. However, the literature suggests that empowerment is a neglected and poorly understood concept by service users and providers alike within epilepsy services. Conceptual ambiguity is a further impediment to its understanding and implementation. Bearing this in mind, a clear definition of empowerment is needed in order to realistically recognize, encourage, and prioritize empowerment as a service design philosophy. Therefore, this paper undertakes a concept analysis of empowerment with reference to epilepsy services. Results indicate that empowerment demands a transformation of consciousness and a readiness to act on this transformation in order to allow people to gain personal power and autonomy over their own life, including the self-management of their condition. With this in mind, a critical reflection on the 'micro' and 'macro' levels of power that exist within epilepsy services is warranted with reference to theoretical principles. In this context although the map is not the terrain, we argue that an educational intervention guided by critical social theory principles has the potential to encourage an understanding of empowerment and 'holds the key' to future advances for its implementation within epilepsy services.

RESUMO

Effective education can support people with epilepsy to develop the attributes and skills required to function as equal partners with clinical service providers, make informed decisions, and competently self-manage their healthcare. However, despite knowledge deficits, unmet information needs, and a poor sense of empowerment, the study of education for people with epilepsy is often neglected and is a poorly understood component of holistic practice within epilepsy healthcare. Historically, the only debate with regard to education and people with epilepsy has been guided either within a positivist or within a constructivist philosophy. We argue that new pedagogies are warranted, recognizing the views of people with epilepsy regarding their illness. Therefore, this paper explores the potential of an educational framework for people with epilepsy based upon critical social theory (CST). By utilizing a CST approach for education, people with epilepsy are engaged with as active 'participants'. This is a key difference that distinguishes CST from other metatheoretical frameworks. It has the potential to support people with epilepsy to acquire the skills and confidence to manage the biopsychosocial challenges associated with their condition.
