The primary objective of our study was to survey ENT surgeons who perform functional endoscopic sinus surgery in the UK regarding their post-sinus surgery practices.
Method
A 28-item questionnaire on post-functional endoscopic sinus surgery practices was distributed electronically to ENT UK members specialising in rhinology.
Results
Ninety (90 per cent) surgeons prescribe saline nasal irrigation post-functional endoscopic sinus surgery but administration timing and methods vary. Following functional endoscopic sinus surgery, 17.7 per cent (n = 17) of respondents routinely prescribe antibiotics, whilst about a quarter (26.0 per cent, n = 25) do not prescribe antibiotics at all. The rest of the respondents only prescribe antibiotics in specific cases. Thirty-three (34.7 per cent) respondents do not prescribe oral steroids whilst most clinicians (83.9 per cent, n = 78) prescribe intranasal corticosteroids post-operatively.
Conclusion
Our study highlights homogeneous, evidence-based practices post-functional endoscopic sinus surgery from UK-based specialists, specifically in the use of saline irrigation and intranasal corticosteroids. However, our cohort displayed significant heterogeneity regarding oral antibiotics, oral steroids, and other specific aspects of post-operative care.
Consistent evidence from retrospective reports and case registry studies indicates that a history of depression is a major risk factor for depression in the peripartum period. However, longitudinal studies with racially and socioeconomically diverse samples of young mothers are lacking, and little is known about developmental patterns of depression across the lifespan that can inform preventive interventions.
Methods
Young primiparous mothers (n = 399, 13–25 years, 81% Black) were recruited from a population-based prospective study that began in childhood. Women reported on depression symptoms for at least 3 years prior to their pregnancy, during pregnancy, and at 4 months postpartum. Linear regression models were used to estimate change in pre-pregnancy depression severity and to evaluate associations between patterns of lifetime history and postpartum depression symptoms.
Results
Results revealed high levels of continuity in depression from pregnancy to postpartum, and across multiple years pre-pregnancy to postpartum. Overall, depression severity leading up to pregnancy decreased over time, but patterns of worsening or improving symptoms were not associated with depression severity in the postpartum period. Instead, area under the pre-pregnancy trajectory curve, representing cumulative lifetime depression burden, was uniquely associated with postpartum depression after adjusting for prenatal depression severity.
Conclusions
Depression in the postpartum period should be considered within a lifespan perspective of risk that accumulates before conception. Clinical screening and early interventions are needed in adolescence and young adulthood to prevent the onset and persistence of depressive symptoms that could have long-term implications for peripartum health.
Although systemic steroids have been shown to improve olfactory function, topical steroids have not demonstrated the same efficacy. This could a result of limited drug delivery to the narrow, superiorly placed olfactory cleft. This study aimed to examine the penetration of intranasal drugs to the olfactory cleft following endonasal balloon dilatation.
Methods
Balloon dilatation was performed in 12 thawed, fresh-frozen cadaver specimens. In the Mygind position, nasal drops mixed with blue food dye were administered into the nostril before and after the dilatation procedure. Endoscopic videos were recorded to assess dye staining of the olfactory cleft and osteo-meatal complex using a 4-point Likert scale.
Results
Prior to balloon dilatation, the mean penetration of nasal drops into the olfactory cleft was 1.34, which improved significantly (p < 0.05) to 2.66 following the procedure. There was no change in dye penetration into the osteo-meatal complex after balloon dilatation.
Conclusion
The results of this exploratory study suggest that balloon dilatation may improve the delivery of nasal drops to the olfactory cleft area. The clinical applicability and impact on olfactory function will require further assessment.
Gut microbiota data obtained by DNA sequencing are not only complex because of the number of taxa that may be detected within human cohorts, but also compositional because characteristics of the microbiota are described in relative terms (e.g., “relative abundance” of particular bacterial taxa expressed as a proportion of the total abundance of taxa). Nutrition researchers often use standard principal component analysis (PCA) to derive dietary patterns from complex food data, enabling each participant's diet to be described in terms of the extent to which it fits their cohort's dietary patterns. However, compositional PCA methods are not commonly used to describe patterns of microbiota in the way that dietary patterns are used to describe diets. This approach would be useful for identifying microbiota patterns that are associated with diet and body composition. The aim of this study is to use compositional PCA to describe gut microbiota profiles in 5 year old children and explore associations between microbiota profiles, diet, body mass index (BMI) z-score, and fat mass index (FMI) z-score. This study uses a cross-sectional data for 319 children who provided a faecal sample at 5 year of age. Their primary caregiver completed a 123-item quantitative food frequency questionnaire validated for foods of relevance to the gut microbiota. Body composition was determined using dual-energy x-ray absorptiometry, and BMI and FMI z-scores calculated. Compositional PCA identified and described gut microbiota profiles at the genus level, and profiles were examined in relation to diet and body size. Three gut microbiota profiles were found. Profile 1 (positive loadings on Blautia and Bifidobacterium; negative loadings on Bacteroides) was not related to diet or body size. Profile 2 (positive loadings on Bacteroides; negative loadings on uncultured Christensenellaceae and Ruminococcaceae) was associated with a lower BMI z-score (r = -0.16, P = 0.003). Profile 3 (positive loadings on Faecalibacterium, Eubacterium and Roseburia) was associated with higher intakes of fibre (r = 0.15, P = 0.007); total (r = 0.15, P = 0.009), and insoluble (r = 0.13, P = 0.021) non-starch polysaccharides; protein (r = 0.12, P = 0.036); meat (r = 0.15, P = 0.010); and nuts, seeds and legumes (r = 0.11, P = 0.047). Further regression analyses found that profile 2 and profile 3 were independently associated with BMI z-score and diet respectively. We encourage fellow researchers to use compositional PCA as a method for identifying further links between the gut, diet and obesity, and for developing the next generation of research in which the impact on body composition of dietary interventions that modify the gut microbiota is determined.
In China, one percent of the richest population holds more than one-third of the wealth, while the poorest 25% shares no more than two percent of the total. The country’s rapid economic development has resulted in increasing socio-economic disparities, and a rapidly deteriorating environment. This puts the Chinese citizens, especially the most vulnerable and deprived socio-economic status (SES) groups, at high risks of environmental inequality (EI). In most SES-based EI studies conducted in China, household wealth has often been overlooked, though it potentially serves a good economic indicator to capture the socio-economic effect of environmental change in China. Nevertheless, existing SES databases in China are of low spatial resolution and are insufficient to support fine-grained EI studies at the intra-city level in China. The core research challenge is to develop a representative household wealth proxy in high-spatial resolution for China. This study highlights the research gaps and proposes a new household wealth proxy, which integrates both fine-grained data/features such as daytime satellite imagery and easily accessible wealth indicators such as house prices. We also capitalize on everyday economic activity data retrieved from personal mobile phones and online transaction/social platforms in the composition of our wealth proxy to achieve a higher accuracy in estimating household wealth at fine-grained resolution via machine learning. Finally, we summarize the challenges in improving both the quality and the availability of Chinese socio-economic datasets, while protecting personal privacy and information security during the data collection process for household wealth proxy development in China.
Dislocation of the cochlear implant magnet is an uncommon but recognised complication of magnetic resonance imaging in a patient with a cochlear implant.
Case report
This paper reports a case of cochlear implant magnet dislocation despite head bandaging. The patient subsequently underwent endoscopic repositioning of the magnet under general anaesthesia. The cochlear implant system was tested intra-operatively and confirmed to be functioning. The patient was well at follow up and the small wound healed well with no complications.
Conclusion
This report presents the endoscopic technique as a viable minimally invasive surgical approach to address cochlear implant magnet dislocation.
Background: Consumer perceptions of care are a key measure of service quality. The Consumer Perceptions of Care (CPoC) survey is often used to assess patients’ evaluations of the quality of services received. Aims: The study explored the factor structure of the CPoC, the relationships between perceived quality of care, empowerment, perceived treatment outcomes, and symptom change, as well as the effect of allowing patients to self-identify during the CPoC survey on their ratings of perceptions of care. Methods: In the first phase of the current study, 2,125 psychiatric inpatients were surveyed about their perceptions of care, and their symptoms were also measured at both admission and discharge. The second phase examined 720 inpatients who had given consent so that perceptions of care could be compared with outcome data. Results: Increased levels of empowerment were associated with favourable ratings of perceived treatment outcomes. Although perceived treatment outcomes and empowerment were correlated with actual symptom change, these correlations were small. Furthermore, the influence of self-identification on ratings of perceptions of care was found to be small. Conclusions: Examining patients’ perceived and actual treatment outcomes may provide mental health service providers with a more nuanced perspective of the hospital experiences of their patients.
Despite evidence linking regular nut consumption with reduced chronic disease risk, population-level intakes remain low. Research suggests nut-promoting advice from doctors facilitates regular nut consumption. However, there is no information on current nut recommendation practices of health professionals. The aim of the present study was to examine the advice provided by health professionals regarding nut consumption.
Design
In this cross-sectional study, participants were invited to complete a survey including questions about their nut recommendation practices.
Setting
New Zealand (NZ).
Subjects
The NZ Electoral Roll was used to identify dietitians, general practitioners and practice nurses.
Results
In total 318 dietitians, 292 general practitioners and 149 practice nurses responded. Dietitians were more likely (82·7 %) to recommend patients increase consumption of nuts than general practitioners (55·5 %) and practice nurses (63·1 %; both P<0·001). The most popular nuts recommended were almonds, Brazil nuts and walnuts, with most health professionals recommending raw nuts. The most common recommendation for frequency of consumption by dietitians and practice nurses was to eat nuts every day, while general practitioners most frequently recommended 2–4 times weekly, although not statistically significantly different between professions. Dietitians recommended a significantly greater amount of nuts (median 30 g/d) than both general practitioners and practice nurses (20 g/d; both P<0·001).
Conclusions
Dietitians were most likely to recommend consumption of nuts in accordance with current guidelines, but there are opportunities to improve the adoption of nut consumption recommendations for all professions. This may be a viable strategy for increasing population-level nut intakes to reduce chronic disease.
Despite considerable evidence supporting the health benefits of regular nut consumption, nut intakes remain lower than recommended among many populations. Understanding how the general population perceives nuts could inform strategies to promote regular nut consumption and increase intakes among the general public.
Design
Cross-sectional study. Participants were invited to complete a questionnaire which included information on nut consumption and knowledge and perceptions of nuts.
Setting
The study was set in New Zealand (NZ).
Subjects
Participants (n 1600), aged 18 years or over, were randomly selected from the NZ electoral roll.
Results
A total of 710 participants completed the questionnaire (response rate 44 %). More than half of the respondents believed that nuts are healthy, filling, high in protein and high in fat. The most common reason cited by consumers for eating nuts was taste (86 % for nuts, 85 % for nut butters), while dental issues was the most frequent reason for avoidance. About 40 % of respondents were not aware of the effects of nut consumption on lowering blood cholesterol and CVD risk.
Conclusions
Despite overall basic knowledge of the nutritional value of nuts, a substantial proportion of the general population was unaware of the cardioprotective effects of nuts. The present study identified common motivations for eating and avoiding nuts, as well as perceptions of nuts which could affect intake. These should guide the content and direction of public health messages to increase regular nut consumption. The public’s knowledge gaps should also be addressed.
Introduction: The risk of recurrent stroke following a transient ischemic attack (TIA) has been estimated to be as much as 5 percent in the first 48 hours and ten percent in the first week following initial TIA symptoms, but can be modified as a result of intensive risk factor management. Care pathways for these patients vary between different regions within Alberta with Edmonton admitting more TIA patients and Calgary using computed tomography angiography (CTA) based triage. To examine regional differences in the quality of care, the rate of admission for stroke within 90 days of an index ED visit for TIA/minor stroke was investigated. Methods: Data analysts from the Data Integration, Measurement and Reporting (DIMR) branch of Alberta Health Services (AHS) used the National Ambulatory Care Reporting System (NACRS) to identify patients in Alberta who were admitted for stroke within 90-days of an index emergency department (ED) visit for TIA/minor stroke from April 2010 to March 2016. Information extracted included patient demographics, region of residence (Edmonton, Calgary or non-major urban [NMU]), return diagnosis and timing of return ED visit. Analysis included descriptive summaries and proportions were compared using a χ2 test. Results: During the study period, there were 26,232 index visits to Alberta EDs for TIA/minor stroke. 5426 (26.1%) of patients were admitted on their index visit. Calgary (22.5%) had lower rates of admission on index visit followed by Edmonton (31.4%) and the NMU (46%). 20,806 (79.3%) were discharged home following their index visit. Of the patients discharged on their index visit 729 (3.5%) had an admission for stroke within 90-days of their index ED visit with rates in Edmonton (3.8%) and the NMU regions (3.8%) being significantly higher than Calgary (2.8%, p<0.01). Conclusion: Our study demonstrates significantly lower rates of admission for stroke within 90-days of ED visit for minor stroke/TIA in Calgary compared to Edmonton and the NMU. Further work should focus on validating this result and consideration of standardized care pathways that promote effective resource utilization and quality of care.
We describe the case of an infant who was a late presenter of transposition of the great arteries where we proceeded with ductal stenting to improve oxygenation and left ventricle training. Stenting improved the infant’s saturation while keeping the left ventricle well trained for 4 months after the procedure. This report demonstrates that intermediate-term left ventricle training can be achieved via ductal stenting.
To conduct the first nationwide population survey to examine the associations between changes in speed of eating and weight gain over 3 years. The study also explored whether faster eating at baseline was related to healthy-weight women becoming overweight after 3 years.
Design
Longitudinal. At baseline, participants were randomly selected from a nationally representative sampling frame to participate in a prospective study. Women completed self-administered baseline questionnaires on demographic and health measures. Self-reported speed of eating, smoking status, physical activity, menopause status, and height and weight were collected at baseline and again 3 years later.
Setting
Nationwide study, New Zealand.
Subjects
Women (n 1601) aged 40–50 years were recruited at baseline from New Zealand electoral rolls.
Results
There was no evidence of associations between 3-year BMI adjusting for baseline BMI and either baseline speed of eating (slower and faster; P=0·524) or change in speed of eating (consistently faster eating, consistently slower eating, slower eating at baseline but not at 3 years, faster eating at baseline but not at 3 years; P=0·845). Of the 488 women with healthy BMI (18·5 to <25·0 kg/m2) at baseline, seventy-seven (15·8 %) became overweight (BMI≥25·0 kg/m2) after 3 years. Compared with those who were slower eaters at baseline, faster eating at baseline did not increase the risk of becoming overweight 3 years later (P=0·958) nor did change in speed of eating (P=0·236).
Conclusions
Results suggest that once women have reached mid-life, faster eating does not predict further weight gain.
The potential efficacy of antifungal agents (e.g. Mycostatin) in treating acute attacks of Ménière's disease was first suggested in 1983 but few data have been published. Oral Mycostatin has been used as second-line medical treatment for intractable Ménière's disease at our institution for many years.
Objective:
This preliminary cohort study investigated the role of oral Mycostatin in intractable Ménière's disease.
Methods:
A retrospective review of patients with intractable Ménière's disease who started oral Mycostatin treatment between 2010 and 2012 was conducted.
Results:
Of 256 patients presenting with vertiginous disorders, 26 had definite Ménière's disease and had not responded to standard first-line treatment. Following oral Mycostatin treatment, improvements were reported for vertigo (n = 8), aural fullness (n = 7), tinnitus (n = 3) and subjective hearing loss (n = 3). Half of those with symptom improvement persisted with oral Mycostatin for two years and continued to remain asymptomatic.
Conclusion:
The use of oral Mycostatin to alleviate symptoms of intractable Ménière's disease showed promising results in this case series. Mycostatin may offer a safe and useful alternative for the management of Ménière's disease for patients with chronic unremitting symptoms in whom first-line treatment options have failed.
The simultaneous insertion of a ventilation tube or grommet during tympanoplasty is a well-recognised practice among otologists. It is used to reverse atelectasis and to repneumatise the middle ear. A troublesome problem which can occur is post-operative, intraluminal grommet obstruction by blood or viscous mucoid secretions. Routine post-operative use of eardrops may help prevent grommet obstruction but cannot be administered after tympanoplasty when the ear canal is packed with dressings for up to three weeks post-operatively. In this article, we describe a simple method to prevent post-tympanoplasty grommet obstruction.
Bilateral sensorineural hearing loss associated with recurrent urticarial skin lesions may be signs of underlying Muckle–Wells syndrome. Previous reports have described the hearing loss to be progressive in nature.
Method:
To our knowledge, this paper presents the first published case of sudden onset, bilateral sensorineural hearing loss associated with urticarial vasculitis due to underlying Muckle–Wells syndrome.
Results:
The patient underwent a cochlear implantation with a modest outcome.
Conclusion:
Cochlear implantation may help to rehabilitate sudden hearing loss associated with this condition, but early diagnosis may allow treatment with interleukin-1β inhibitors such as anakinra.
Semiconductor nanocrystals or quantum dots are becoming increasingly popular in research fields as wide ranging as cancer therapies, solar energy and disease detection. Colloidal synthesis provides a low-cost method of producing high quality quantum dots with narrow size distributions. The controllable nature of colloidal synthesis allows researchers to design the size, shape and surface functionalization of the resulting particles.
Here we investigate a simple low temperature method to produce CdSe quantum dots. The quantum dots were grown in solution by dissolving the CdO precursor in a mixture of macadamia oil, and oleic acid. Elemental Se was heated separately before the two mixtures were combined under an inert atmosphere. The injection temperature, reaction temperature and oleic acid concentration were all varied.
Optical absorption and photoluminescence spectroscopies showed the size of the quantum dots increased with time, temperature and oleic acid concentration. Dynamic light scattering has shown the hydrodynamic particle size to range from 7 to 22nm and the samples for up to 6 months.
To analyze infectious complications that occur in patients who receive extracorporeal membrane oxygenation (ECMO), associated risk factors, and consequences on patient outcome.
Design.
Retrospective observational survey from 2005 through 2011.
Participants and Setting.
Patients who required ECMO in an Australian referral center.
Methods.
Cases of bloodstream infection (BSI), catheter-associated urinary tract infection (CAUTI), and ventilator-associated pneumonia (YAP) that occurred in patients who received ECMO were analyzed.
Results.
A total of 146 ECMO procedures were performed for more than 48 hours in 139 patients, and 36 patients had a total of 46 infections (30.1 infectious episodes per 1,000 days of ECMO). They included 24 cases of BSI, 6 of them secondary to VAP; 23 cases of VAP; and 5 cases of CAUTI. The most frequent pathogens were Enterobacteriaceae (found in 16 of 46 cases), and Candida was the most common cause of BSI (in 9 of 24 cases). The Sequential Organ Failure Assessment score before ECMO initiation and the number of days of support were independenuy associated with a risk of BSI, with odds ratios of 1.23 (95% confidence interval [CI], 1.03-1.47; P = .019) and 1.08(95% CI, 1.03-1.19]; P = .006), respectively. Infected patients did not have a significantly higher mortality compared with uninfected patients (41.7% vs 32%; P = .315), but intensive care unit length of stay (16 days [interquartile range, 8-26 days] vs 11 days [IQR, 4-19 days]; P = .012) and hospital length of stay (33.5 days [interquartile range, 15.5-55.5] vs 24 days [interquartile range, 9-42 days]; P = .029) were longer.
Conclusion.
The probability of infection increased with the duration of support and the severity of illness before initiation of ECMO. Infections affected length of stay but did not have an impact on mortality.
To determine the feasibility and safety of the Conquest Pro wire as an alternative to radiofrequency wire for perforation of atretic pulmonary valve and subsequent balloon dilatation and patent ductus arteriosus stenting in patients with pulmonary atresia with intact ventricular septum.
Background
Radiofrequency valvotomy and balloon dilatation has become the standard of care for pulmonary atresia with intact ventricular septum in many institutions today.
Methods
We report eight consecutive patients in whom we used the Conquest Pro coronary guidewire, a stiff wire normally reserved for revascularisation of coronary lesions with chronic total occlusion, for perforation of atretic pulmonary valve and subsequent balloon dilatation, and stenting of the patent ductus arteriosus.
Results
Perforation of atretic pulmonary valve was successful in seven out of eight cases. Radiofrequency valvotomy was employed after failure of perforation by the Conquest Pro wire in one case where the right ventricular outflow tract was broad based and tapered towards the pulmonary valve, and was heavily trabeculated. Failure of the Conquest Pro wire to perforate the pulmonary valve plate was mainly attributed by the failure to engage the wire at the correct position.
Conclusion
The Conquest Pro wire for perforation and subsequent interventions in the more straightforward cases of pulmonary atresia with intact ventricular septum is effective and safe, simplifying the entire procedure. However, the radiofrequency generator and wires remain essential tools in the paediatric interventional catheter laboratory.
To examine the association between eating in response to hunger and satiety signals (intuitive eating) and BMI. A second objective was to determine whether the hypothesized higher BMI in less intuitive eaters could be explained by the intake of specific foods, speed of eating or binge eating.
Design
Cross-sectional survey. Participants were randomly selected from a nationally representative sampling frame. Eating in response to hunger and satiety signals (termed ‘intuitive eating’), self-reported height and weight, frequency of binge eating, speed of eating and usual intakes of fruits, vegetables and selected high-fat and/or high-sugar foods were measured.
Setting
Nationwide study, New Zealand.
Subjects
Women (n 2500) aged 40–50 years randomly selected from New Zealand electoral rolls, including Māori rolls (66 % response rate; n 1601).
Results
Intuitive Eating Scale (IES) scores were significantly associated with BMI in an inverse direction, after adjusting for potential confounding variables. When controlling for confounding variables, as well as potential mediators, the inverse association between intuitive eating (potential range of IES score: 21–105) and BMI was only slightly attenuated and remained statistically significant (5·1 % decrease in BMI for every 10-unit increase in intuitive eating; 95 % CI 4·2, 6·1 %; P < 0·0 0 1). The relationship between intuitive eating and BMI was partially mediated by frequency of binge eating.
Conclusions
Eating in response to hunger and satiety signals is strongly associated with lower BMI in mid-age women. The direction of causality needs to be investigated in longitudinal studies and randomized controlled trials.
