ObjectivesAsthma exacerbation, associated with many risks factors, can reflect management failure. However, little is known about how risk factors are associated with exacerbation, according to asthma severity. We aimed to investigate differences in risk factors in patients with different asthma severity and evaluate whether risk factors differed between frequent exacerbators and patients with single exacerbation.DesignNationwide population-based observational study.SettingKorean National Sample Cohort database.ParticipantsWe included 22 130 adults with asthma diagnoses more than twice (ICD-10 (International Classification of Diseases, Tenth revision) codes J45 and J46) and one prescription for asthma medication from 2010 to 2011.Outcome measuresAsthma exacerbation was defined as having a corticosteroid (CS) burst characterised by a prescription of high-dose oral CS for ≥3 days or one systemic CS injection, hospitalisation or emergency department visit.ResultsAmong severities, history of CS bursts was significantly associated with exacerbation. In mild and moderate asthma, exacerbation was significantly associated with age ≥45 years, being female, gastro-oesophageal reflux disease and chronic rhinitis. High medication possession ratio (MPR≥50%), compared with low MPR (<20%) showed adjusted ORs of 0.828 (95% CI 0.707 to 0.971) and 0.362 (0.185 to 0.708) in moderate and severe asthma, respectively. In severe asthma, compared with mild asthma, only allergic rhinitis and history of hospitalisation were strongly associated with exacerbation. When comparing frequent exacerbators to patients with single exacerbation, age ≥45 years, atopic dermatitis, anxiety and history of CS burst were significant risk factors in mild and moderate asthma, whereas no risk factors were significant in severe asthma.ConclusionsDifferent associations between risk factors and asthma exacerbations based on asthma severity suggest that patients with mild asthma require greater attention to their age and comorbidities, whereas those with severe asthma require greater attention to hospitalisation history and drug adherence.

Background: Severe asthma exacerbation is one of the common pediatric medical emergencies that necessitates hospital visits. The study aimed to identify risk factors associated with pediatric severe asthma exacerbations that might have the potential to guide the parents for early medical consultations and physicians at primary health care centers for proper management.Methods: A case-control study was conducted on over 100 asthmatic children below 12 years attending the Emergency Department of Alexandria University Children’s Hospital in acute exacerbation. Based on a modified pulmonary index score, the patients were allocated into 2 groups; study group (50 patients with severe asthma exacerbation) and control group (50 patients with mild asthma exacerbations). Demographic data, history of illness, alarming clinical signs, medications, and outcome of all participants were recorded.Results: Severe asthma exacerbations were more encountered among males, older age, and with a longer duration of asthma (X±SD=28.4±15.9 months) with significant differences when compared to controls. Comparing the studied groups revealed higher risk for severe asthma exacerbations mainly with; history of sudden onset of severe respiratory distress (Odds ratio “OR”=30.13, 95% CI, 13.78-66.69) and chronic steroid-dependent asthma (OR=14.46, 95% CI, 3.97-52.65). Cyanosis, lethargy, and inability to talk were alarming signs in patients with severe asthma exacerbation when compared to those with mild asthma exacerbation (p<0.05).Conclusions: Severe asthma exacerbation in children is still associated with many risk factors that may alert the patients’ caregivers and physicians prospectively for early proper management.

Ventilation Heterogeneity

AbstractSmall airway disease, characterised by ventilation heterogeneity (VH), is present in a subgroup of patients with asthma. Ventilation heterogeneity can be measured using multiple breath washout testing. Few studies have been reported in children. We studied the relationship between VH, asthma severity, and spirometry in a cross-sectional observational cohort study involving children with stable mild-moderate and severe asthma by GINA classification and a group of healthy controls. Thirty-seven participants aged 5–16 years completed multiple breath nitrogen washout (MBNW) testing (seven controls, seven mild-moderate asthma, 23 severe asthma). The lung clearance index (LCI) was normal in control and mild-moderate asthmatics. LCI was abnormal in 5/23 (21%) of severe asthmatics. The LCI negatively correlated with FEV1z-score.Conclusion: VH is present in asthmatic children and appears to be more common in severe asthma. The LCI was significantly higher in the cohort of children with severe asthma, despite no difference in FEV1 between the groups. This supports previous evidence that LCI is a more sensitive marker of airway disease than FEV1. MBNW shows potential as a useful tool to assess children with severe asthma and may help inform clinical decisions. What is Known:• Increased ventilation heterogeneity is present in some children with asthma• Spirometry is not sensitive enough to detect small airway involvement in asthma What is New• Lung clearance index is abnormal in a significant subgroup of children with severe asthma but rarely in children with mild-moderate asthma• Our data suggests that LCI monitoring should be considered in children with severe asthma

Background: Identification of subjects with a progressive disease phenotype is an urgent need in the pharmaceutical industry where most of the recent clinical trials in Alzheimer’s disease have failed. Objectives: The objective of this study was to identify subgroups of individuals with objective cognitive impairment (OCI), who were most likely to progress to dementia and to identify the risk factors associated with progression. Design: Prospective cohort study. Setting: Population-based. Participants: 5,380 elderly women from Denmark. Measurements: The Short Blessed Test and a category fluency test with animal naming, was used to assess cognitive function, and to classify them into different groups of OCI. Results: OCI was identified in 852 subjects at baseline. The risk of dementia was elevated for OCI subjects as compared to subjects with normal cognition (HR 1.46[1.19-1.79]). The courses of OCI were studied in a sub-cohort who completed the cognitive assessment at both the baseline and the follow-up visit (n = 1,933). Of these subjects 203 had OCI at baseline. The multi-domain subtypes of OCI were associated with progressive OCI. Subjects most likely to progress were older, physically inactive, had a higher level of total cholesterol (>6.5 mmol/L) and had a history of depression as compared to subjects with a non-progressive course of OCI. Conclusions: In this cohort we identified a risk profile associated with progression from OCI in older women. The degree of impairment at baseline was an important predictor of conversion to dementia, additionally several modifiable risk factors were associated with progression.

In this study, we sought to determine whether asthma has a metabolic profile and whether this profile is related to disease severity.We characterised the serum from 22 healthy individuals and 54 asthmatics (12 mild, 20 moderate, 22 severe) using liquid chromatography–high-resolution mass spectrometry-based metabolomics. Selected metabolites were confirmed by targeted mass spectrometry assays of eicosanoids, sphingolipids and free fatty acids.We conclusively identified 66 metabolites; 15 were significantly altered with asthma (p≤0.05). Levels of dehydroepiandrosterone sulfate, cortisone, cortisol, prolylhydroxyproline, pipecolate and N-palmitoyltaurine correlated significantly (p<0.05) with inhaled corticosteroid dose, and were further shifted in individuals treated with oral corticosteroids. Oleoylethanolamide increased with asthma severity independently of steroid treatment (p<0.001). Multivariate analysis revealed two patterns: 1) a mean difference between controls and patients with mild asthma (p=0.025), and 2) a mean difference between patients with severe asthma and all other groups (p=1.7×10−4). Metabolic shifts in mild asthma, relative to controls, were associated with exogenous metabolites (e.g. dietary lipids), while those in moderate and severe asthma (e.g. oleoylethanolamide, sphingosine-1-phosphate, N-palmitoyltaurine) were postulated to be involved in activating the transient receptor potential vanilloid type 1 (TRPV1) receptor, driving TRPV1-dependent pathogenesis in asthma.Our findings suggest that asthma is characterised by a modest systemic metabolic shift in a disease severity-dependent manner, and that steroid treatment significantly affects metabolism.

BackgroundDiabetes prevalence estimates suggest an increasing trend in South-East Asia region, but studies on its incidence are limited. The current study aims to estimate the incidence of type 2 diabetes and pre-diabetes in a population-based cohort from India.MethodsA subset of Chandigarh Urban Diabetes Study cohort (n=1878) with normoglycaemia or pre-diabetes at baseline was prospectively followed after a median of 11 (0.5–11) years. Diabetes and pre-diabetes were diagnosed as per WHO guidelines. The incidence with 95% CI was calculated in 1000 person-years and Cox proportional hazard model was used to find the association between the risk factors and progression to pre-diabetes and diabetes.ResultsThe incidence of diabetes, pre-diabetes and dysglycaemia (either pre-diabetes or diabetes) was 21.6 (17.8–26.1), 18.8 (14.8–23.4) and 31.7 (26.5–37.6) per 1000 person-years, respectively. Age (HR 1.02, 95% CI 1.01 to 1.04), family history of diabetes (HR 1.56, 95% CI 1.09 to 2.25) and sedentary lifestyle (HR 1.51, 95% CI 1.05 to 2.17) predicted conversion from normoglycaemia to dysglycaemia, while obesity (HR 2.43, 95% CI 1.21 to 4.89) predicted conversion from pre-diabetes to diabetes.ConclusionA high incidence of diabetes and pre-diabetes in Asian-Indians suggests a faster conversion rate to dysglycaemia, which is partly explained by sedentary lifestyle and consequent obesity in these individuals. The high incidence rates call for a pressing need for public health interventions targeting modifiable risk factors.

Abstract Aim Compared with the general population, individuals with schizophrenia have a higher risk of periodontal disease, which can potentially reduce their life expectancy. However, evidence for the early development of periodontal disease in schizophrenia is scant. The current study investigated risk factors for periodontal disease in patients newly diagnosed with schizophrenia. Methods We identified a population-based cohort of patients in Taiwan with newly diagnosed schizophrenia who developed periodontal disease within 1 year of their schizophrenia diagnosis. Treatment with antipsychotics and other medications was categorised according to medication type and duration, and the association between medication use and the treated periodontal disease was assessed through logistic regression. Results Among 3610 patients with newly diagnosed schizophrenia, 2373 (65.7%) had an incidence of treated periodontal disease during the 1-year follow-up. Female sex (adjusted odds ratios [OR] 1.40; 95% confidence interval [CI] 1.20–1.63); young age (adjusted OR 0.99; 95% CI 0.98–0.99); a 2-year history of periodontal disease (adjusted OR 2.45; 95% CI 1.84–3.26); high income level (adjusted OR 2.24; 95% CI 1.64–3.06) and exposure to first-generation (adjusted OR 1.89; 95% CI 1.54–2.32) and secondary-generation (adjusted OR 1.33; 95% CI 1.11–1.58) antipsychotics, anticholinergics (adjusted OR 1.24; 95% CI 1.03–1.50) and antihypertensives (adjusted OR 1.91; 95% CI 1.64–2.23) were independent risk factors for periodontal disease. Hyposalivation – an adverse effect of first-generation antipsychotics (FGAs) (adjusted OR 2.00; 95% CI 1.63–2.45), anticholinergics (adjusted OR 1.27; 95% CI 1.05–1.53) and antihypertensives (adjusted OR 1.90; 95% CI 1.63–2.22) – was associated with increased risk of periodontal disease. Therefore, hypersalivation due to FGA use (adjusted OR 0.72; 95% CI 0.59–0.88) was considered a protective factor. Conclusions The current study highlights that early prevention of periodontal disease in individuals with schizophrenia is crucial. Along with paying more attention to the development of periodontal disease, assessing oral health regularly, helping with oral hygiene, and lowering consumption of sugary drinks and tobacco, emphasis should also be given by physicians to reduce the prescription of antipsychotics to the extent possible under efficacious pharmacotherapy for schizophrenia.

Background. The development of drug dependence requires prior initiation. What is the relationship between the risk factors for initiation and dependence?Methods. Using smoking as a model addiction, we assessed smoking initiation (SI) and nicotine dependence (ND) by personal interview in 1898 female twins from the population-based Virginia Twin Registry. We developed a twin structural equation model that estimates the correlation between the liability to SI and the liability to ND, given SI.Results. The liabilities to SI and ND were substantially correlated but not identical. Heritable factors played an important aetiological role in SI and in ND. While the majority of genetic risk factors for ND were shared with SI, a distinct set of familial factors, which were probably partly genetic, solely influenced the risk for ND. SI was associated with low levels of education and religiosity, high levels of neuroticism and extroversion and a history of a wide range of psychiatric disorders. ND was associated with low levels of education, extroversion, mastery, and self-esteem, high levels of neuroticism and dependency and a history of mood and alcohol use disorders.Conclusions. The aetiological factors that influence SI and ND, while overlapping, are not perfectly correlated. One set of genetic factors plays a significant aetiological role in both SI and ND, while another set of familial factors, probably in part genetic, solely influences ND. Some risk factors for SI and ND impact similarly on both stages, some act at only one stage and others impact differently and even in opposite directions at the two stages. The pathway to substance dependence is complex and involves multiple genetic and environmental risk factors.

Aim/Introduction. This study was carried out to assess the incidence and risk factors of diabetic foot ulcer (DFU). Materials and Methods. In this prospective cohort study in a university hospital, all the participants were examined and followed up for new DFU as final outcome for two years. To analyze the data, the variables were first evaluated with a univariate analysis. Then variables with P value < 0.2 were tested with a multivariate analysis, using backward-elimination multiple logistic regression. Results. Among 605 patients, 39 cases had DFU, so we followed up the remaining 566 patients without any present or history of DFU. A two-year cumulative incidence of diabetic foot ulcer was 5.62% (95% CI 3.89–8.02). After analysis, previous history of DFU or amputation [OR = 9.65, 95% CI (2.13–43.78), P value = 0.003], insulin usage [OR = 5.78, 95% CI (2.37–14.07), P value < 0.01], gender [OR = 3.23, 95% CI (1.33–7.83), P value = 0.01], distal neuropathy [OR = 3.37, 95% CI (1.40–8.09), P value = 0.007], and foot deformity [OR = 3.02, 95% CI (1.10–8.29), P value = 0.032] had a statistically significant relationship with DFU incidence. Conclusion. Our data showed that the average annual DFU incidence is about 2.8%. Independent risk factors of DFU development were previous history of DFU or amputation, insulin consumption, gender, distal neuropathy, and foot deformity. These findings provide support for a multifactorial etiology for DFU.

The Impact

Purpose of StudyAsthma is typically treated acutely with β2-agonists and systemic steroids. Adjunctive therapies such as magnesium sulfate (MgSO4) have proven useful with early addition potentially improving clinical outcomes in asthma (reduced hospital admission rates, length of stay and intubation rates). Exact administration time and impact on outcomes in children are not fully understood. We sought to identify the impact of timing of initiating MgSO4 therapy in innercity children admitted for status asthmaticus.Methods UsedWe performed a retrospective chart review of children (age 2–21 yrs) admitted to a children's hospital over a 12 month period with asthma exacerbation and administered MgSO4. Data collected included ethnicity, gender, medications, timing of interventions, length of stay, BMI percentile, comorbidities and NAEPP asthma severity. Statistical analysis performed with SPSS 22.Summary of Results150 innercity children were admitted for asthma exacerbation and received MgSO4 during the study period. 85% were African American, 36% female, 39% had moderate/severe asthma and mean time to initial MgSO4 was 3.8 hours from triage. Those receiving initial MgSO4 after 4 hours were more likely to receive multiple doses of MgSO4 (OR2.8 [95%CI:1.4–5.6]). Time of initial MgSO4 dose (<4 vs. >4 hrs) showed no significant difference in other parameters including age, obesity, asthma severity, and comorbidities. A sub-analysis of children that received 1 dose vs. >1 MgSO4 dose demonstrated that those receiving >1 MgSO4 doses were more likely to be obese (OR2.7 [1.3–5.7]), have moderate/severe asthma (OR3.2 [1.6–6.8]) and have increased length of stay (p=0.005) and charges (p=0.042). Additionally, obese children (OR8.9 [2.2–35.2]), and intermittent/mild asthmatic children (OR6.4 [1.2–31.2]) receiving >1 MgSO4 dose were more likely to have >2 day length of stay.ConclusionsDelay in administration of MgSO4 in children hospitalized for status asthmaticus may be associated with poor outcomes including multiple doses of MgSO4 which in turn is associated with longer length of stay and increased charges. Obesity and asthma severity are important factors associated with these outcomes. A prospective analysis in a larger cohort is recommended to further evaluate these findings.
