Costs of UK community care for individuals with recessive dystrophic epidermolysis bullosa: Findings of the Prospective Epidermolysis Bullosa Longitudinal Evaluation Study.

Background: Recessive dystrophic epidermolysis bullosa (RDEB) is a rare inherited skin fragility disorder requiring multidisciplinary management. Information regarding costs of current standard treatment is scant. Objectives: As part of a longitudinal natural history study, we explored the community care costs of UK patients with different forms of RDEB. Methods: Fifty-nine individuals with RDEB provided detailed information on multiple facets of RDEB including disease severity scores (iscorEB, BEBS) and patient reported outcomes (quality of life evaluation in epidermolysis bullosa, iscorEB patient questionnaire). Costs data included time spent doing dressings, frequency of dressing changes, details of materials used, and paid and unpaid care. Results: Overall costs of dressing materials and associated care were high in RDEB. Median annual costs across all subtypes for those using dressings (n = 51) were over £26 000. For severe RDEB (RDEB-S), median costs were almost £90 000 per annum, with a median of 18 h per week spent on dressing changes. Half of working-age adults with RDEB were unemployed and 39% of carers were unable to take on full-time or part-time paid employment, adding to indirect costs and the financial burden from RDEB on families and society. Conclusions: The findings demonstrate the high costs of care of RDEB, particularly for RDEB-S. The current expense supports the drive to develop new therapies which accelerate wound healing and diminish total wound burden, thereby reducing costs of dressings and care. While costly to bring to market, these might ultimately reduce the overall cost of treatment and also the impact on individuals living with this rare disease. The data also highlight the need for adequate reimbursement for EB care which can place significant financial strain on families.

Itch in recessive dystrophic epidermolysis bullosa: findings of PEBLES, a prospective register study.

BACKGROUND: Itch is common and distressing in epidermolysis bullosa (EB) but has not previously been studied in depth in different recessive dystrophic EB (RDEB) subtypes. OBJECTIVES: As part of a prospective register study of the natural history of RDEB we explored features of itch, medications used, and correlation with disease severity and quality of life. METHODS: Fifty individuals with RDEB aged 8 years and above completed the Leuven Itch Scale (LIS) (total 243 reviews over a 7-year period). Data included itch frequency, severity, duration, distress, circumstances, consequences, itch surface area and medications for itch. The iscorEB disease severity score and the validated EB quality of life tool, QOLEB, were compared to LIS domains and analysed by RDEB subtype. RESULTS: Itch was frequent, present in the preceding month in 93% of reviews. Itch severity and distress were significantly greater in severe (RDEB-S) and pruriginosa (RDEB-Pru) subtypes compared to intermediate RDEB (RDEB-I). Itch medications were reported in just over half of reviews including emollients, topical corticosteroids and antihistamines; the proportion of participants not using medication despite frequent pruritus suggests limited efficacy. In inversa RDEB (RDEB-Inv) and RDEB-I, LIS domains correlated with iscorEB and QOLEB. In contrast to previous studies, correlations were lacking in RDEB-S suggesting that global disease burden relatively reduces the contribution of itch. CONCLUSIONS: This comprehensive study of RDEB-associated itch highlights differences between RDEB subtypes, suggests an unmet need for effective treatments and could serve as control data for future clinical trials incorporating itch as an endpoint.

Longitudinal changes in lung function in very prematurely born young people receiving high-frequency oscillation or conventional ventilation from birth.

OBJECTIVE: To examine changes in lung function over time in extremely prematurely born adolescents. WORKING HYPOTHESIS: Changes in lung function during adolescence would vary by ventilation mode immediately after birth. STUDY DESIGN: Longitudinal follow-up study. PATIENT SUBJECT SELECTION: Participants from the United Kingdom Oscillation Study who were randomized at birth to high-frequency oscillation (HFO) or conventional ventilation (CV) were assessed at 11-14 years (n = 319) and at 16-19 years (n = 159). METHODOLOGY: Forced expiratory flow (FEF), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and lung volumes including functional residual capacity (FRC) were reported as z-scores. The diffusion capacity of the lungs for carbon monoxide (DLCO) was measured. Lung function trajectories were compared by mode of ventilation using mixed models. Changes in z-scores were scaled to 5-year average follow-up. RESULTS: There were significant changes in the mean FEF75, FEF50, FEF25, FEV1, FVC, and DLCO z-scores within the CV and HFO cohorts, but no significant differences in the changes between the two groups. The mean FRC z-score increased in both groups, with an average change of greater than one z-score. The mean FEV1/FVC z-score increased significantly in the CV group, but not in the HFO group (difference in slopes: p = 0.02). Across the population, deterioration in lung function was associated with male sex, white ethnicity, lower gestational age at birth, postnatal corticosteroids, oxygen dependency at 36 weeks postmenstrual age, and lower birth weight, but not ventilation mode. CONCLUSIONS: There was little evidence that the mode of ventilation affected changes in lung function over time.

Factors affecting dementia care practitioners' decision-making on moves to a care home for persons living with dementia: A factorial survey.

Deciding if and when might be the 'optimal' time for a person living with dementia to move to a care home is often difficult for the individual, family and practitioners. In this study, we describe the outcome of a factorial survey conducted with 100 dementia care practitioners (a frontline health or social care worker who works with people living with dementia) in England, which investigated factors used in deciding when a person living with dementia moves to a care home. Using findings from qualitative interviews with older people living with dementia, family carers, care home managers and social workers, we identified four factors that appeared to influence the decision to move to a care home: (1) Family carers' ability to support the person with daily activities, (2) amount of support provided by home care workers, (3) level of risk of harm and (4) the person living with dementia's wishes. These factors were then randomised within skeleton vignettes that told the story of a fictitious woman (Jane) living with dementia at home with her husband. Fifty-four variations of the vignettes were produced and randomly assigned to 100 surveys. A total of 100 volunteer dementia care practitioners (78% female, 54% over 50 years of age) received their own personalised online survey link via email and were asked to read each vignette and decide whether to suggest Jane (a) move to a care home or (b) continue living at home. Results indicated that Jane's wishes principally drove most dementia care practitioners' decision on whether to suggest a move to a care home or stay living at home (odds ratio = 6.5-19.5). Findings will inform a better understanding of the factors that contribute toward a decision to move to a care home and be of relevance to policy, practice, training and support.

Identifying multimorbidity clusters with the highest primary care use: 15 years of evidence from a multi-ethnic metropolitan population.

BACKGROUND: People with multimorbidity have complex healthcare needs. Some co-occurring diseases interact with each other to a larger extent than others and may have a different impact on primary care use. AIM: To assess the association between multimorbidity clusters and primary care consultations over time. DESIGN AND SETTING: A retrospective longitudinal (panel) study design was used. Data comprised electronic primary care health records of 826 166 patients registered at GP practices in an ethnically diverse, urban setting in London between 2005 and 2020. METHOD: Primary care consultation rates were modelled using generalised estimating equations. Key controls included the total number of long-term conditions, five multimorbidity clusters, and their interaction effects, ethnic group, and polypharmacy (proxy for disease severity). Models were also calibrated by consultation type and ethnic group. RESULTS: Individuals with multimorbidity used two to three times more primary care services than those without multimorbidity (incidence rate ratio 2.30, 95% confidence interval = 2.29 to 2.32). Patients in the alcohol dependence, substance dependence, and HIV cluster (Dependence+) had the highest rate of increase in primary care consultations as additional long-term conditions accumulated, followed by the mental health cluster (anxiety and depression). Differences by ethnic group were observed, with the largest impact in the chronic liver disease and viral hepatitis cluster for individuals of Black or Asian ethnicity. CONCLUSION: This study identified multimorbidity clusters with the highest primary care demand over time as additional long-term conditions developed, differentiating by consultation type and ethnicity. Targeting clinical practice to prevent multimorbidity progression for these groups may lessen future pressures on primary care demand by improving health outcomes.

Inequalities in developing multimorbidity over time: A population-based cohort study from an urban, multi-ethnic borough in the United Kingdom.

BACKGROUND: Social and material deprivation accelerate the development of multimorbidity, yet the mechanisms which drive multimorbidity pathways and trajectories remain unclear. We aimed to examine the association between health inequality, risk factors and accumulation or resolution of LTCs, taking disease sequences into consideration. METHODS: We conducted a retrospective cohort of adults aged 18 years and over, registered between April 2005 and May 2020 in general practices in one inner London borough (n = 826,936). Thirty-two long term conditions (LTCs) were selected using a consensus process, based on a definition adapted to the demographic characteristics of the local population. sThe development and resolution of these LTCs were examined according to sociodemographic and clinical risk factors (hypertension; moderate obesity (BMI 30·0-39·9 kg/m2), high cholesterol (total cholesterol > 5 mmol/L), smoking, high alcohol consumption (>14 units per week), and psychoactive substance use), through the application of multistate Markov chain models. FINDINGS: Participants were followed up for a median of 4.2 years (IQR = 1·8 - 8·4); 631,760 (76%) entered the study with no LTCs, 121,424 (15%) with 1 LTC, 41,720 (5%) with 2 LTCs, and 31,966 (4%) with three or more LTCs. At the end of follow-up, 194,777 (24%) gained one or more LTCs, while 45,017 (5%) had resolved LTCs and 27,021 (3%) died. In multistate models, deprivation (hazard ratio [HR] between 1·30 to 1·64), female sex (HR 1·13 to 1·20), and Black ethnicity (HR 1·20 to 1·30; vs White) were independently associated with increased risk of transition from one to two LTCs, and shorter time spent in a healthy state. Substance use was the strongest risk factor for multimorbidity with an 85% probability of gaining LTCs over the next year. First order Markov chains identified consistent disease sequences including: chronic pain or osteoarthritis followed by anxiety and depression; alcohol and substance dependency followed by HIV, viral hepatitis, and liver disease; and morbid obesity followed by diabetes, hypertension, and chronic pain. INTERPRETATION: We examined the relations among 32 LTCs, taking the order of disease occurrence into consideration. Distinctive patterns for the development and accumulation of multimorbidity have emerged, with increased risk of transitioning from no conditions to multimorbidity and mortality related to ethnicity, deprivation and gender. Musculoskeletal disorders, morbid obesity and substance abuse represent common entry points to multimorbidity trajectories.

Identifying longitudinal clusters of multimorbidity in an urban setting: A population-based cross-sectional study.

BACKGROUND: Globally, there is increasing research on clusters of multimorbidity, but few studies have investigated multimorbidity in urban contexts characterised by a young, multi-ethnic, deprived populations. This study identified clusters of associative multimorbidity in an urban setting. METHODS: This is a population-based retrospective cross-sectional study using electronic health records of all adults aged 18 years and over, registered between April 2005 to May 2020 in general practices in one inner London borough. Multiple correspondence analysis and cluster analysis was used to identify groups of multimorbidity from 32 long-term conditions (LTCs). RESULTS: The population included 41 general practices with 826,936 patients registered between 2005 and 2020, with mean age 40 (SD15·6) years. The prevalence of multimorbidity was 21% (n = 174,881), with the median number of conditions being three and increasing with age. Analysis identified five consistent LTC clusters: 1) anxiety and depression (Ratio of within- to between- sum of squares (WSS/BSS <0·01 to <0·01); 2) heart failure, atrial fibrillation, chronic kidney disease (CKD), chronic heart disease (CHD), stroke/transient ischaemic attack (TIA), peripheral arterial disease (PAD), dementia and osteoporosis (WSS/BSS 0·09 to 0·12); 3) osteoarthritis, cancer, chronic pain, hypertension and diabetes (0·05 to 0·06); 4) chronic liver disease and viral hepatitis (WSS/BSS 0·02 to 0·03); 5) substance dependency, alcohol dependency and HIV (WSS/BSS 0·37 to 0·55). INTERPRETATION: Mental health problems, pain, and at-risk behaviours leading to cardiovascular diseases are the important clusters identified in this young, urban population. FUNDING: Impact on Urban Health, United Kingdom.

Applying resolved and remission codes reduced prevalence of multimorbidity in an urban multi-ethnic population.

OBJECTIVE: To estimate the prevalence and determinants of multimorbidity in an urban, multi-ethnic area over 15-years and investigate the effect of applying resolved/remission codes on prevalence estimates. STUDY DESIGN AND SETTING: This is a population-based retrospective cross-sectional study using electronic health records of adults registered between 2005 -2020 in general practices in one inner London borough (n = 826,936). Classification of resolved/remission was based on clinical coding defined by the patient's general practitioner. RESULTS: The crude and age-adjusted prevalence of multimorbidity over the study period were 21.2% (95% CI: 21.1 -21.3) and 30.8% (30.6 -31.0), respectively. Applying resolved/remission codes decreased the crude and age-adjusted prevalence estimates to 18.0% (95% CI: 17.9 -18.1) and 27.5% (27.4 -27.7). Asthma (53.2%) and depression (20.2%) were responsible for most resolved and remission codes. Substance use (Adjusted Odds Ratio 10.62 [95% CI: 10.30 -10.95]), high cholesterol (2.48 [2.44 -2.53]), and moderate obesity (2.19 [2.15 -2.23]) were the strongest risk factor determinants of multimorbidity outside of advanced age. CONCLUSION: Our study highlights the importance of applying resolved/remission codes to obtain an accurate prevalence and the increased burden of multimorbidity in a young, urban, and multi-ethnic population. Understanding modifiable risk factors for multimorbidity can assist policymakers in designing effective interventions to reduce progression to multimorbidity.

The ROX index has greater predictive validity than NEWS2 for deterioration in Covid-19.

BACKGROUND: Patients admitted to hospital with Covid-19 are at risk of deterioration. The National Early Warning Score (NEWS2) is widely recommended, however it's validity in Covid-19 is not established and indices more specific for respiratory failure may be more appropriate. We aim to describe the physiological antecedents to deterioration, test the predictive validity of NEWS2 and compare this to the ROX index ([SpO2/FiO2]/respiratory rate). METHOD: A single centre retrospective cohort study of adult patients who were admitted to a medical ward, between 1/3/20 and 30/5/20, with positive results for SARS-CoV-2 RNA. Physiological observations and the NEWS2 were extracted and analysed. The primary outcome was a composite of cardiac arrest, unplanned critical care admission or death within 24 hours. A generalized linear model was used to assess the association of physiological values, NEWS2 and ROX with the outcome. FINDINGS: The primary outcome occurred in 186 patients (26%). In the preceding 24 hours, deterioration was most marked in respiratory parameters, specifically in escalating oxygen requirement; tachypnoea was a late sign, whilst cardiovascular observations remained stable. The area under the receiver operating curve was 0.815 (95% CI 0.804-0.826) for NEWS2 and 0.848 (95% CI 0.837-0.858) for ROX. Applying the optimal level of ROX, the majority of patients triggered four hours earlier than with NEWS2 of 5. INTERPRETATION: NEWS2 may under-perform in Covid-19 due to intrinsic limitations of the design and the unique pathophysiology of the disease. A simple index utilising respiratory parameters can outperform NEWS2 in predicting the occurrence of adverse events.

Intrauterine growth retardation and lung function of very prematurely born young people.

OBJECTIVES: To assess if intrauterine growth retardation (IUGR) was associated with reduced lung function at 16-19 years. WORKING HYPOTHESIS: Very prematurely born young people who had IUGR would have reduced lung function postpuberty. STUDY DESIGN: Prospective follow-up study. PATIENT-SUBJECT SELECTION: One hundred and fifty-nine 16-19 year olds born before 29 weeks of gestation; 37 had IUGR. METHODOLOGY: Lung function tests were performed: spirometry was used to assess forced expiratory volume in one second (FEV1), forced expiratory flow at 75%, 50% and 25% of expired vital capacity (FEF75, FEF50 and FEF25), peak expiratory flow (PEF) and forced vital capacity (FVC). Functional residual capacity (FRCpleth) total lung capacity (TLCpleth) and residual volume (RVpleth) were measured. Alveolar function was assessed by diffusion capacity within the lungs of carbon monoxide (DLCO). Impulse oscillometry was used to assess respiratory resistance and lung clearance index to assess ventilation homogeneity. Exercise capacity was assessed using a shuttle sprint test. RESULTS: After adjustment for BMI, the mean FEV-1/FVC, FEF75, FEF25-75, FRCpleth and RVpleth were poorer in those who had had IUGR, with differences between 0.56 and 0.75 z-scores. After further adjustment for BPD and postnatal corticosteroid use, only the difference in RVpleth z-scores remained statistically significant, adjusted difference (95% CI): 0.66 (0.18,1.13). Exercise capacity was lower in those with IUGR and this was more pronounced in males (p=0.04). CONCLUSIONS: At 16-19 years of age, those who had IUGR had poorer lung function and exercise capacity compared with those with adequate intrauterine growth.

Maternal cardiac adaptation and fetal growth.

BACKGROUND: Pregnancies with small-for-gestational-age fetuses are at increased risk of adverse maternal-fetal outcomes. Previous studies examining the relationship between maternal hemodynamics and fetal growth were mainly focused on high-risk pregnancies and those with fetuses with extreme birthweights, such as less than the 3rd or 10th percentile and assumed a similar growth pattern in fetuses above the 10th percentile throughout gestation. OBJECTIVE: This study aimed to evaluate the trends in maternal cardiac function, fetal growth, and oxygenation with advancing gestational age in a routine obstetrical population and all ranges of birthweight percentiles. STUDY DESIGN: This was a prospective, longitudinal study assessing maternal cardiac output and peripheral vascular resistance by bioreactance at 11+0 to 13+6, 19+0 to 24+0, 30+0 to 34+0, and 35+0 to 37+0 weeks' gestation, sonographic estimated fetal weight in the last 3 visits and the ratio of the middle cerebral artery by umbilical artery pulsatility indices or cerebroplacental ratio in the last 2 visits. Women were divided into the following 5 groups according to birthweight percentile: group 1, <10th percentile (n=261); group 2, 10 to 19.9 percentile (n=180); group 3, 20 to 29.9 percentile (n=189); group 4, 30 to 69.9 percentile (n=651); and group 5, ≥70th percentile (n=508). The multilevel linear mixed-effects model was performed to compare the repeated measures of hemodynamic variables and z scores of the estimated fetal weight and cerebroplacental ratio. RESULTS: In visit 2, compared with visit 1, in all groups, cardiac output increased, and peripheral vascular resistance decreased. At visit 3, groups 1, 2, and 3, compared with 4 and 5, demonstrated an abrupt decrease in cardiac output and increase in peripheral vascular resistance. From visit 2, group 1 had a constant decline in estimated fetal weight, coinciding with the steepest decline in maternal cardiac output and rise in peripheral vascular resistance. In contrast, in groups 4 and 5, the estimated fetal weight had a stable or accelerative pattern, coinciding with the greatest increase in cardiac output and lowest peripheral vascular resistance. Groups 2 and 3 showed a stable growth pattern with intermediate cardiac output and peripheral vascular resistance. Increasing birthweight was associated with higher cerebroplacental ratio. Groups 3, 4, and 5 had stable cerebroplacental ratio across visits 3 and 4, whereas groups 1 and 2 demonstrated a significant decline (P<.001). CONCLUSION: In a general obstetrical population, maternal cardiac adaptation at 32 weeks' gestation parallels the pattern of fetal growth and oxygenation; babies with birthweight<20th percentile have progressive decline in fetal cerebroplacental ratio, decline in maternal cardiac output, and increase in peripheral vascular resistance.

Impact of multimorbidity on healthcare costs and utilisation: a systematic review of the UK literature.

BACKGROUND: Managing multimorbidity is complex for both patients and healthcare systems. Patients with multimorbidity often use a variety of primary and secondary care services. Country-specific research exploring the healthcare utilisation and cost consequences of multimorbidity may inform future interventions and payment schemes in the UK. AIM: To assess the relationship between multimorbidity, healthcare costs, and healthcare utilisation; and to determine how this relationship varies by disease combinations and healthcare components. DESIGN AND SETTING: A systematic review. METHOD: This systematic review followed the bidirectional citation searching to completion method. MEDLINE and grey literature were searched for UK studies since 2004. An iterative review of references and citations was completed. Authors from all articles selected were contacted and asked to check for completeness of UK evidence. The National Institutes of Health National Heart, Lung, and Blood Institute quality assessment tool was used to assess risk of bias. Data were extracted, findings synthesised, and study heterogeneity assessed; meta-analysis was conducted when possible. RESULTS: Seventeen studies were identified: seven predicting healthcare costs and 10 healthcare utilisation. Multimorbidity was found to be associated with increased total costs, hospital costs, care transition costs, primary care use, dental care use, emergency department use, and hospitalisations. Several studies demonstrated the high cost of depression and of hospitalisation associated with multimorbidity. CONCLUSION: In the UK, multimorbidity increases healthcare utilisation and costs of primary, secondary, and dental care. Future research is needed to examine whether integrated care schemes offer efficiencies in healthcare provision for multimorbidity.

Postnatal dexamethasone exposure and lung function in adolescents born very prematurely.

We previously demonstrated corticosteroid administration on the neonatal intensive care unit was associated with reduced lung function at 11 to 14 years of age in children born very prematurely. The objective of this observational study was to assess if lung function remained impaired at 16 to 19 years of age in those who had received postnatal corticosteroids and whether the trajectory of lung function with increasing age differed between those who had and had not received corticosteroids. One hundred and fifty-nine children born prior to 29 weeks of gestational age had comprehensive lung function measurements; 49 had received postnatal dexamethasone. Lung function outcomes were compared between those who had and had not received postnatal dexamethasone after adjustment for neonatal factors. Forced expiratory flow at 75%, 50%, 25% and 25-75% of the expired vital capacity, forced expiratory volume in one second, peak expiratory flow and forced vital capacity and lung volumes (total lung capacity and residual volume) were assessed. The majority of results were significantly lower in those who received dexamethasone (between 0.61 to 0.78 standard deviations). Lung function reduced as the number of courses of dexamethasone increased. Between 11 and 14 years and 16 to 19 years, lung function improved in the unexposed group, but forced expiratory flow at 75% of the expired vital capacity and forced expiratory volume in one second deteriorated in those who had received postnatal corticosteroids (p = 0.0006). These results suggest that prematurely born young people who received postnatal corticosteroids may be at risk of premature onset of chronic obstructive pulmonary disease.

Lung function and exercise capacity in prematurely born young people.

OBJECTIVES: To determine if lung function abnormalities in young people born very prematurely routinely exposed to antenatal corticosteroids and postnatal surfactant were associated with reduced exercise capacity. WORKING HYPOTHESIS: In the current era, lung function abnormalities would not be associated with exercise intolerance STUDY DESIGN: Follow-up of young people from the United Kingdom Oscillation study (UKOS). PATIENT-SUBJECT SELECTION: One hundred twenty-six young people of 797 recruited to UKOS, born at a mean gestational age of 27 weeks were assessed at a mean age of 17 years. METHODOLOGY: Forced expiratory flow at 75% of the expired vital capacity (FEF75 ), forced expiratory volume in 1 second (FEV1 ) and lung volumes (forced vital capacity [FVC]) and residual volume (RV) and functional residual capacity (FRCpleth ) were assessed. Abnormal lung function was below the fifth centile and very abnormal lung function below the 2.5th centile. Exercise capacity was assessed using a modified shuttle sprint test and self-reported hours of exercise. RESULTS: Thirty-nine young people had an abnormal FEF75 with an adjusted reduction in sprint distance of 114 m (P = .018) and an adjusted difference in self-reported exercise of 0.73 hours (P = .036). Twenty-seven young people had a very abnormal FEF75 with an adjusted reduction in sprint distance of 159 m (P = .002) and adjusted reduction in self-reported exercise of 1.15 hours (P = .002). CONCLUSION: Very prematurely born young people with abnormal airway function had a significant reduction in exercise capacity.

Lung function and respiratory outcomes in teenage boys and girls born very prematurely.

OBJECTIVES: Male sex in prematurely born infants has been associated with worse respiratory outcomes in early childhood. WORKING HYPOTHESIS: Respiratory outcomes at 11 to 14 years of age in children born very prematurely and routinely exposed to antenatal corticosteroids and postnatal surfactant would differ according to sex. STUDY DESIGN: Analysis of follow-up data. PATIENT-SUBJECT SELECTION: Three hundred and nineteen children born before 29 weeks of gestational age from the United Kingdom Oscillation Study. METHODOLOGY: Spirometry was used to assess forced expiratory flow at 75%, 50%, and 25% of expired vital capacity (FEF75 , FEF50 , and FEF25 ), forced expiratory volume in 1 second (FEV1 ), peak expiratory flow (PEF), and forced vital capacity (FVC). Lung volumes were measured using a helium dilution technique (FRCHe ) and by plethysmography (FRCpleth ). Total lung capacity (TLC) and residual volume (RV) were calculated. Mean lung function measurements were compared using linear mixed models and reported as unadjusted and adjusted for neonatal and age 11 to 14 years factors. The participants also completed health questionnaires and provided a urine sample for assessment of passive or active smoking. RESULTS: Three (FEF25 , FEF25-75 , FEV1 ) lung function measures showed significant differences in favor of females after adjustment. The percentage of children with abnormal lung function (below 5th centile for normal) had adjusted differences between 10 and 30 percentage points, for example, for FEF25 15% females compared with 26% males. CONCLUSIONS: Among extremely prematurely born school children airway function was significantly worse in males.

Long-Term Trends in Stroke Survivors Discharged to Care Homes: The South London Stroke Register.

Background and Purpose- Care homes provide care to many stroke survivors, yet little is known about changes in care home use over time. We aim to determine trends in discharge to care homes, to explore the characteristics of stroke survivors over time (1995-2018), and to identify the associations between these characteristics and discharge to care homes poststroke. Methods- Using data from the South London Stroke Register between 1995 and 2018, we estimated the proportions discharged to care homes and their characteristics over time, assessed by tests for trends. Multivariable logistic regression models were built to assess the associations between their characteristics and discharge destination. Results- Of 4172 stroke survivors, 484 (12%) were discharged to care homes. This proportion has decreased from 24% in 1995 to 2000 to 5% in 2013 to 2018. The mean age of those discharged to care homes has increased over time, from 73 to 75 (P<0.001). Among stroke survivors discharged to a care home, the proportion with a prestroke Barthel Index <15 has also increased over time from 7% to 21% (P=0.027), while the proportion with a 7-day poststroke Barthel Index <15 remains largely unchanged over time (93% in 1995-2000, 90% in 2013-2018). The characteristics most strongly associated with discharge to care homes were (odds ratio [95% CI]) age (1.05 [1.04-1.07] per year), stroke subtype (hemorrhagic; 0.64 [0.43-0.95]), stroke severity (Glasgow Coma Scale score, <13; 1.67 [1.19-2.35]), failed swallow test at admission (1.65 [1.20-2.25]), 7-day poststroke Barthel Index <15 (3.58 [2.20-6.03]), and a longer hospital stay (1.02 [1.02-1.03] per day). Conclusions- Over >20 years, there has been an 80% reduction in the proportion of stroke survivors discharged to care homes, influenced by changes in the demographics, disability, and stroke care in the underlying stroke population. In those moving to care homes, the level of poststroke disability remains high, requiring continued attention and investment.

The effect of parity on longitudinal maternal hemodynamics.

BACKGROUND: Parous women have a lower risk for pregnancy complications, such as preeclampsia or delivery of small-for-gestational-age neonates. However, parous women are a heterogeneous group of patients because they contain a low-risk cohort with previously uncomplicated pregnancies and a high-risk cohort with previous pregnancies complicated by preeclampsia and/or small for gestational age. Previous studies examining the effect of parity on maternal hemodynamics, including cardiac output and peripheral vascular resistance, did not distinguish between parous women with and without a history of preeclampsia or small for gestational age and reported contradictory results. OBJECTIVE: The objective of the study was to compare maternal hemodynamics in nulliparous women and in parous women with and without previous preeclampsia and/or small for gestational age. STUDY DESIGN: This was a prospective, longitudinal study of maternal hemodynamics, assessed by a bioreactance method, measured at 11+0 to 13+6, 19+0 to 24+0, 30+0 to 34+0, and 35+0 to 37+0 weeks' gestation in 3 groups of women. Group 1 was composed of parous women without a history of preeclampsia and/or small for gestational age (n = 632), group 2 was composed of nulliparous women (n = 829), and group 3 was composed of parous women with a history of preeclampsia and/or small for gestational age (n = 113). A multilevel linear mixed-effects model was performed to compare the repeated measures of hemodynamic variables controlling for maternal characteristics, medical history, and development of preeclampsia or small for gestational age in the current pregnancy. RESULTS: In groups 1 and 2, cardiac output increased with gestational age to a peak at 32 weeks and peripheral vascular resistance showed a reversed pattern with its nadir at 32 weeks; in group 1, compared with group 2, there was better cardiac adaptation, reflected in higher cardiac output and lower peripheral vascular resistance. In group 3 there was a hyperdynamic profile of higher cardiac output and lower peripheral vascular resistance at the first trimester followed by an earlier sharp decline of cardiac output and increase of peripheral vascular resistance from midgestation. The incidence of preeclampsia and small for gestational age was highest in group 3 and lowest in group 1. CONCLUSION: There are parity-specific differences in maternal cardiac adaptation in pregnancy.

Factors, trends, and long-term outcomes for stroke patients returning to work: The South London Stroke Register.

BACKGROUND AND PURPOSE: There is limited information on factors, trends, and outcomes in return to work at different time-points post-stroke; this study aims to identify these in a multi-ethnic urban population. METHODS: Patterns of return to work were identified in individuals in paid work prior to first-ever stroke in the population-based South London Stroke Register (SLSR) between 1995 and 2014. Multivariable logistic regression examined associations between patient characteristics and return to work at 1 year (1 y), 5 years (5 y) and 10 years (10 y) post-stroke. RESULTS: Among 5609 patients, 940 (17%) were working prior to their stroke, of whom 177 (19%) were working 3 months post-stroke, declining to 172 (18%) at 1 y, 113 (12%) at 5 y, and 27 (3%) at 10 y. Factors associated with return to work within 1 y, after logistic regression, included functional independence (BI ≥ 19; p < 0.01) and shorter length of stay (p < 0.05). Younger age (p < 0.01) was associated with return to work at 5 y and 10 y post-stroke. Non-manual occupation (p < 0.05) was associated with return to work at 10 y post-stroke. Return to work within 1 y increased the likelihood of working at 5 y (OR: 13.68; 95% CI 5.03-37.24) and 10 y (9.07; 2.07-39.8). Of those who were independent at follow-up (BI ≥ 19), 48% were working at 1 y, 42% at 5 y, and 28% at 10 y. Lower rates of anxiety and depression and higher self-rated health were associated with return to work at 1 y (p < 0.01). CONCLUSION: Although functionally independent stroke survivors are more likely to return to work long-term, a large proportion do not return to work despite functional independence. Return to work post-stroke is associated with improved long-term psychological outcomes and quality of life.

Composite Grafts for Pediatric Fingertip Amputations: A Retrospective Case Series of 100 Patients.

BACKGROUND: Fingertip amputations are common. This study reports on the outcomes of composite grafts used for fingertip amputations in children, measuring graft take, predictors of graft take, complications, and patient-reported outcomes. METHODS: A retrospective case series of consecutive patients (≤ 16 years) undergoing composite grafts for fingertip amputations in a tertiary pediatric hospital, January 06 to December 16, was performed. Information was collected on amputations, graft take, and complications. Logistic regression was used to analyze factors predicting graft take (partial/complete or failure) including age; amputation level; mechanism and time delay to surgery. Patients were contacted via post or telephone to ask about functional and cosmetic outcomes and their perception of graft take. RESULTS: One hundred patients [57 (57%) males; mean age, 4.41 ± 3.98 years], presenting with 100 fingertip amputations, met the inclusion criteria. Amputation mechanism was crush in 75 (75%), avulsion in 13 (13%), and laceration in 12 (13%). Thirteen (13%) composite grafts survived completely, 46 (46%) partially, and 41 (41%) failed. Graft survival was higher in children under 4 years (P = 0.016). Seventeen (17%) grafts became infected, 9 (9%) required a reoperation, 9 (9%) had wound healing complications, and 4 (4%) patients developed psychological complications. Patient-reported survival was 33% higher than medical-reported survival. Cosmetic issues were the commonest complication reported by patients. Patients rated fingertips looking 3.5/5 normal, and that they were 4/5 satisfied with the appearance. Most patients were using their fingers normally by 2-6 months. CONCLUSIONS: Composite grafts for fingertip amputations mostly only partially survive, but morbidity is low, patient satisfaction is high, and acceptable cosmetic and functional outcomes are achieved.
