Authors: Wakefield Dominique , Bayly Jo , Selman Lucy Ellen , Firth Alice M , Higginson Irene J , Murtagh Fliss EM 
Published: June 2018

Background: Patient empowerment, defined as ‘a process through which people gain greater control over decisions and actions affecting their health’ (World Health Organization) is a key theme within global health and social care strategies. The benefits of incorporating empowerment strategies in care are well documented, but little is known about their application or impact for patients with advanced, life-limiting illness(s). Aim: To identify and synthesise the international evidence on patient empowerment for adults with advanced, life-limiting illness(s). Design: Systematic review (PROSPERO no. 46113) with critical interpretive synthesis methodology. Data sources: Five databases (MEDLINE, Embase, CINHAL, PsycINFO and Cochrane) were searched from inception to March 2018. Grey literature and reference list/citation searches of included papers were undertaken. Inclusion criteria: empirical research involving patients with advanced life-limiting illness including descriptions of, or references to, patient empowerment within the study results. Results: In all, 13 papers met inclusion criteria. Two qualitative studies explored patient empowerment as a study objective. Six papers evaluated interventions, referencing patient empowerment as an incidental outcome. The following themes were identified from the interpretive synthesis: self-identity, personalised knowledge in theory and practice, negotiating personal and healthcare relationships, acknowledgement of terminal illness, and navigating continued losses. Conclusion: There are features of empowerment, for patients with advanced life-limiting illness distinct to those of other patient groups. Greater efforts should be made to progress the empowerment of patients nearing the end of their lives. We propose that the identified themes may provide a useful starting point to guide the assessment of existing or planned services and inform future research.

Background: Advance care planning is seen as an important strategy to improve end-of-life communication and the quality of life of patients and their relatives. However, the frequency of advance care planning conversations in practice remains low. In-depth understanding of patients’ experiences with advance care planning might provide clues to optimise its value to patients and improve implementation. Aim: To synthesise and describe the research findings on the experiences with advance care planning of patients with a life-threatening or life-limiting illness. Design: A systematic literature review, using an iterative search strategy. A thematic synthesis was conducted and was supported by NVivo 11. Data sources: The search was performed in MEDLINE, Embase, PsycINFO and CINAHL on 7 November 2016. Results: Of the 3555 articles found, 20 were included. We identified three themes in patients’ experiences with advance care planning. ‘Ambivalence’ refers to patients simultaneously experiencing benefits from advance care planning as well as unpleasant feelings. ‘Readiness’ for advance care planning is a necessary prerequisite for taking up its benefits but can also be promoted by the process of advance care planning itself. ‘Openness’ refers to patients’ need to feel comfortable in being open about their preferences for future care towards relevant others. Conclusion: Although participation in advance care planning can be accompanied by unpleasant feelings, many patients reported benefits of advance care planning as well. This suggests a need for advance care planning to be personalised in a form which is both feasible and relevant at moments suitable for the individual patient.

Published: June 2018

Aims: We examined whether the use of a renin-angiotensin-aldosterone system (RAS) inhibitor plays a role in protecting against left atrial appendage thrombus (LAAT) in patients with hypertension complicated by atrial fibrillation (AF). Methods: Two observational studies were conducted on patients with diagnoses of hypertension and AF, who were categorized into RAS inhibitor user or nonuser groups. Demographic characteristics, clinical characteristics, echocardiographic parameters and hemostatic markers were examined and the occurrence of LAAT during follow-up were recorded. Results: In the first study ( n = 131), LA peak systolic strain and LAA emptying flow velocity (LAA eV) were significantly increased in patients on RAS inhibitors compared with the nonuser group ( p < 0.05). Lower D-dimer and fibrinogen levels were observed in patients on RAS inhibitors ( p < 0.05). In the second study ( n = 99), 25.9% ( n = 11) of patients on RAS inhibitors developed LAAT, compared with 46.7% ( n = 21) in the nonuser group ( p < 0.05). After controlling for risk factors related to LAAT, use of RAS inhibitors remained associated with a significantly lower risk of developing LAAT (HR, 0.406; 95% CI, 0.191–0.862; p = 0.019). Conclusions: RAS inhibitors use was associated with a significant reduction in the risk of LAAT in patients with hypertension and AF.

Published: June 2018

Introduction: Aldosterone decreases at high altitude (HA) but the effect of hypoxia on angiotensin-converting enzyme (ACE), a key step in the renin-angiotensin-aldosterone system, is unclear. Methods: We investigated the effects of exercise and acute normobaric hypoxia (NH, ~11.0% FiO2) on nine participants and six controls undertaking the same exercise at sea level (SL). NH exposure lasted 5 hours with 90 minutes of submaximal treadmill walking. Blood samples for aldosterone, ACE and cortisol were taken throughout exposure and at rest during a trek to HA (5140 m) in eight separate participants. Results: There was no difference in cortisol or aldosterone between groups pre-exercise. Aldosterone rose with exercise to a greater extent at SL than in NH (post-exercise: 700 ± 325 versus 335 ± 238 pmol/L, mean ± SD, p = 0.044). Conversely, cortisol rose to a greater extent in NH (post-exercise: 734 ± 165 versus 344 ± 159 nmol/L, mean ± SD, p = 0.001). There were no differences in ACE activity. During the trek to HA, resting aldosterone and cortisol reduced with no change in ACE. Conclusions: Acute NH subdues the exercise-associated rise in aldosteroe but stimulates cortisol, whereas prolonged exposure at HA reduces both resting aldosterone and cortisol. As ACE activity was unchanged in both environments, this is not the mechanism underlying the fall in aldosterone.

Background and aim We sought to determine the effect of regression to normal glucose tolerance (NGT) or progression to diabetes in early years of impaired glucose tolerance (IGT) on subsequent risk of stroke. Methods In 1986, 576 adults aged 25 years and older with impaired glucose tolerance in Da Qing, China, were randomly assigned by clinic to control, diet, exercise, or diet plus exercise intervention groups for a six-year period. Subsequently participants received medical care in their local clinics. We tracked participants for additional 17 years to ascertain stroke events and other outcomes. Results At the end of 6-year intervention trial follow-up, 272 (50.2%) had progressed to diabetes, 169 (31.2%) regressed to normal glucose tolerance, and 101 (18.6%) remained impaired glucose tolerance. During the subsequent 17-year follow-up, 173 (31.9%) developed a stroke, 26.7% of normal glucose tolerances, 30.7% of impaired glucose tolerances, and 36.1% of those with diabetes. After controlling for age, sex, baseline blood pressure, smoking, total cholesterol, previous cardiovascular disease and intervention group, those who developed diabetes in the first six years had a higher incidence of stroke than those who reverted to normal glucose tolerance (HR = 1.49, 95% CI 1.01–2.19, p = 0.04), whereas for those who remained impaired glucose tolerance compared to those who regressed to normal glucose tolerance the HR was 1.25 (95% CI 0.80–1.93; p = 0.30). A 1-mmol/L increase in both fasting and 2-h post-load plasma glucose from entry to end of the six-year trial was significantly associated with a higher risk of development of stroke in the subsequent 17 years, respectively (HR = 1.07, 95% CI 1.03–1.11, p < 0.0001 for fasting glucose, HR = 1.05, 95% CI 1.02–1.09, p = 0.007 for 2-h post-load plasma glucose). Conclusions Among Chinese adults with impaired glucose tolerance, early progression to diabetes predicted a higher risk of stroke, compared those who regressed to normal glucose tolerance.
Physiotherapy practice in pulmonary hypertension: physiotherapist and patient perspectives
Authors: Keen Carol , Fowler‐Davis Sally , McLean Sionnadh , Manson Jane 
Published: June 2018

Pulmonary hypertension (PH) is a life‐limiting disease affecting circulation to the lungs. The primary symptom of PH is breathlessness, yet research has shown that patients with PH can exercise safely and can benefit from exercise to improve exercise capacity and maintain quality of life. This study aimed to investigate the nature of physiotherapy delivered to patients with PH in the UK. This was a two‐phase sequential, exploratory, mixed‐methods study. Interviews were conducted with seven lead physiotherapists at specialist pulmonary hypertension centers and three patients. Survey data came from 63 physiotherapists caring for patients with PH in specialist and non‐specialist settings. The findings from the two phases were triangulated and analyzed. Findings showed that physiotherapists and patients see the benefit and potential of physical activity for patients with PH to maintain functional wellbeing. However, current physiotherapy provision focuses on acute inpatient care and planning for discharge and is not therefore aligned with research evidence and clinical guidelines. In the absence of inpatient rehabilitation facilities, physiotherapists will occasionally access existing community services, e.g. pulmonary rehabilitation; however, specialist knowledge of this rare condition can be lacking in local services. There is aspiration among physiotherapists and patients for a new approach which supports patients from diagnosis with PH to end of life. This includes promoting and delivering rehabilitation and exercise interventions to achieve better health outcomes, in line with patient needs. Treatment would be commissioned and delivered within existing national health systems with physiotherapists developing strategies for health improvement.

Published: June 2018

Background Indication of omalizumab in the United States was recently extended to include pediatric (6–11 years) uncontrolled moderate-to-severe allergic asthma patients. Objective The purpose of this study was to describe baseline characteristics of this population from a real-world dataset. Methods Allergic asthma patients and uncontrolled moderate-to-severe allergic asthma patients, aged 6–11 years, were identified in the Allergy Partners Network Electronic Medical Records (2007–2016). The index date for allergic asthma patients was the latest between the second asthma-related visit and the allergic status confirmation. Uncontrolled moderate-to-severe allergic asthma patients were stratified into omalizumab-exposed (index date) or omalizumab-unexposed (index date randomly generated) groups. Characteristics were evaluated during the 12-month preindex period. Results A total of 5806 allergic asthma, 37 omalizumab-exposed, and 2620 omalizumab-unexposed patients were selected (mean age approximately 9 years). Allergic asthma and omalizumab-unexposed patients were predominantly white (70.2% and 61.2%) whereas the majority of omalizumab-exposed were African Americans (62.2%). Mean immunoglobulin E was 782.0 IU/ml in allergic asthma patients (available in 2.2%), 1134.4 IU/ml in omalizumab-exposed (available in 100.0%), and 746.1 IU/ml in omalizumab-unexposed (available in 3.1%). Allergic asthma patients were less severe than omalizumab-exposed and omalizumab-unexposed based on the forced expiratory volume in 1 s as a percentage of predicted value (FEV1% predicted) and the Childhood Asthma Control Test (C-ACT). FEV1% predicted was below normal (<80%) in 42.4% of omalizumab-exposed and 39.1% of omalizumab-unexposed patients, also 63.6% of omalizumab-exposed and 46.7% of omalizumab-unexposed had uncontrolled asthma (C-ACT score <20). In African American omalizumab-exposed patients, FEV1% predicted was below normal in 47.6% and 55.0% had uncontrolled asthma. Conclusions In a real-world setting, pediatric patients with uncontrolled moderate-to-severe allergic asthma have a significant disease burden as shown by high rates of poor lung function, disease control, and symptoms. Currently available treatments could help improve disease management in this population.

Published: June 2018

Background Epithelial-myoepithelial carcinoma (EMC) is a rare tumor of the major and minor salivary glands. Sinonasal EMC is extremely uncommon and hitherto not described within the frontal or ethmoid sinuses. Objective To present a novel sinonasal subsite and review the literature regarding sinonasal EMC. Methods A case of frontoethmoidal EMC was presented. A medical literature data base was queried from January 1, 1950, to August 8, 2017, for all reports of sinonasal EMC. Results A 69-year-old man underwent combined open and endoscopic craniofacial resection of a right frontoethmoidal EMC, a previously undescribed primary location for this tumor. A comprehensive review of the literature revealed 13 additional cases of sinonasal EMC. Conclusion EMC is an uncommon neoplasm typically found in the major salivary glands; occurrence in the nose or paranasal sinuses is extremely rare. EMC often follows an indolent clinical course, although, in a minority of cases, particularly in large tumors with nuclear atypia, more aggressive behavior may be observed.
Diagnostic dilemmas of mechanical restriction of the medial rectus: A case report
Authors: Gallogly James A. , Faraji Farhoud , Jumaily Mejd H. , Schneider John S. , Brunworth Joseph D. 
Published: June 2018

Background Due to the proximity of the maxillary sinus and ethmoid sinuses to the orbit, inflammatory processes that originate in the sinonasal region have the potential to extend into the orbit. Objective We presented a case of ptosis and restrictive strabismus of the medial rectus muscle. Methods A case report with a literature review of possible diagnoses. Results Biopsy, imaging, and laboratory evaluation by otolaryngology, ophthalmology, and rheumatology services were unable to identify the cause of the fibrosis after 22 months of follow-up. A response to oral steroids indicated an inflammatory process. Conclusion Unilateral mechanical restriction of the medial rectus muscle is a rare complication of nasal disease. Inflammatory processes and iatrogenic injury are known to cause fibrosis of surrounding tissue. We presented a unique case of medial rectus fibrosis that did not meet the diagnostic criteria of recognized etiologies.

Published: June 2018

Background Rhinitis is a very common disease with allergies being the most frequent causative factor. It can co-occur together with asthma and eczema in atopic as well as in nonatopic patients. Objectives To assess the prevalence of allergic sensitization within patient groups with rhinitis in consideration of the co-occurring disorders of asthma and eczema. Methods Students of the third year of medical school completed an anonymous questionnaire on age, gender, and clinical symptoms, such as seasonal rhinitis, perennial rhinitis, asthma, and eczema, and underwent an ImmunoCAP Rapid test. We calculated the prevalence of sensitization within subgroups of patients reporting allergic disorders, such as rhinitis, asthma, and eczema. Results Questionnaires and ImmunoCAP Rapid tests of 1513 medical students were analyzed. The participants’ self-reported presence of seasonal/perennial rhinitis, asthma, and eczema was compared to the presence of sensitization. Data of 1467 subjects could be analyzed. Seasonal rhinitis was the most common symptom, followed by eczema, asthma, and perennial rhinitis. The participants were differentiated into 16 subgroups according to the combined clinical manifestations of the different symptoms and association to sensitization within subgroups. The prevalence of sensitization ranged from 18% in subjects reporting only eczema without any other symptom to 100% in those reporting to have asthma, seasonal/perennial rhinitis, and eczema together. In subjects reporting no sign or symptom at all, the prevalence of sensitization was 19%. Seasonal rhinitis was the strongest single predictor for sensitization with the highest proportion of sensitized participants in all symptom combinations (67%–100%), followed by perennial rhinitis (31%–100%), asthma (30%–100%), and eczema (18%–100%). Conclusion Rhinitis most often is associated with allergen sensitization, and the probability of sensitization is substantially enhanced by co-occurrence of asthma. A careful assessment of clinical signs and symptoms is important and enables the selection of patients in whom targeted diagnostic analysis and therapy is appropriate.

Authors: Rao Nikhil G. , Kumar Ambuj , Wong Jenny S. , Shridhar Ravi , Goswami Dharendra Y. 
Published: June 2018

Background Photoelectrochemical oxidation (PECO) is a new air purification technology developed to reduce circulating indoor allergens. PECO removes particles as small as 0.1 nm with the destruction of organic matter otherwise not trapped by a traditional filter and removes volatile organic compounds. Objective We hypothesized that with daily use, the device would reduce user nasal and ocular allergy total symptom scores (TSS) within 4 weeks. Methods The study was performed among 46 individuals with self-reported allergies using a portable PECO air purifier. Self-reported TSS were calculated at baseline and weekly for 4 weeks following initiation of continuous use of the system. TSS was the sum of total nasal symptom scores (TNSS) and total ocular symptom scores (TOSS) for the week. Results There was a statistically significant change in overall TSS from baseline to 4 weeks (10.1 at baseline and 4.35 postintervention) resulting in a mean difference of 5.75 (95% confidence interval [CI] 4.32–7.18; P < .0001). There was a statistically significant change in TNSS from baseline to 4 weeks (6.3 at baseline and 3.04 postintervention) resulting in a mean difference of 3.26 (95% CI 2.33–3.19; P < .0001). There was a statistically significant change in TOSS from baseline to 4 weeks (3.82 at baseline and 1.3 postintervention) resulting in a mean difference of 2.52 (95% CI 1.74–3.3; P < .0001). Conclusion With the use of PECO air purification technology, TSS, TNSS, and TOSS decreased significantly. These improvements were consistent over the 4-week course of device use.
Review of 16 cases of aneurysmal bone cyst in the proximal femur treated by extended curettage and cryosurgery with reconstruction using autogenous nonvascularized fibula graft
Authors: Rahman Mohamed Abdel , El Masry Ayman Mohammad , Azmy Sherif Ishak 
Published: June 2018

Background: Aneurysmal bone cyst (ABC) is an aggressive benign lesion that may sometimes be difficult to treat. Lesions that occur in the proximal femur require to be addressed aggressively because of the high rate of local recurrence and the risk of fracture. Few articles report the experience of management of ABC in the proximal femur. This location presents a surgical challenge due to its anatomical and biomechanical peculiarity. Methods: We retrospectively reviewed 16 cases with ABC in the proximal femur that were treated in our institution between 2005 and 2014, utilizing extended curettage and liquid nitrogen as adjuvant therapy and reconstruction using nonvascularized autogenous fibular strut graft. The mean follow-up period was 50.5 months. Five cases presented as recurrent cases, while four cases presented with pathological fractures. Results: The functional score ranged from 70 to 90 on modified Musculoskeletal Tumor Society score with a mean score of 81.25, which is considered to be excellent function. Time for graft incorporation ranged from 10 to 12 weeks. One case got local recurrence, and one case got early surgical site infection. Conclusions: Extended curettage and cryotherapy represent a recommended approach for management of ABC in the proximal femur with favorable results.
Triage Nurses Decision-Support Application Design
Authors: Levis Tamari , Schwartz Dagan , Bitan Yuval 
Published: June 2018

In this paper, we will present the planning and design process of a triage decision-support application, aimed to be used for both research data gathering and real-time triage decision-making. Triage is an initial classification of emergency department (ED) patients, according to the severity level of their medical condition. The need of fast and accurate triage decision-making, lead to the development of widely used triage algorithms, such as ESI (Emergency Severity Index). Observations and interviews with triage personnel exposed difficulties of triage process and helped us create an ESI-based decision making model. Next, we built a multiple-choice questioner to characterize the application and required features. 40 triage nurses completed the questioner. Results indicated that the most highly requested feature was an automated severity grade calculator, which became the core of the proposed design. While current design focuses on the analytical decision model, statistical analysis of the questioner results indicated that it is often insufficient when facing medical reality complexities, dictating nurse’s frequent use of intuition. Using triage systems data analysis and modern machine-learning methodologies, we inspire to develop a second version of the application that will integrate intuitive insights into triage scale algorithmic decision process.
