BackgroundDepression is a common and potentially debilitating illness worldwide. Attendance to routine childcare appointments is a key point of interest in the effort to improve the health and care for families facing depression.AimTo evaluate the association between maternal depression and offspring non-attendance to the Danish childcare and vaccination programme (CCP) for children from 0–5 years of age. The CCP consists of seven separate visits and several vaccinations. To investigate if exposure to recent and previous depression may affect attendance differently.Design and settingPopulation-based cohort study using Danish nationwide registers.MethodParticipants were all live-born children (n = 853 315) in Denmark in the period from 1 January 2000 until 31 August 2013, and their mothers. The outcome of interest was non-attendance of each one of the seven scheduled childcare visits and two vaccination entities in the CCP. Exposure was maternal (both previous and recent) depression. All information was obtained from Danish national registries.ResultsThe risk of not attending CCP was higher for children of mothers with depression. For children of mothers with previous depression, the relative risk (RR) was 1.01 (95% confidence interval [CI] = 0.98 to 1.03) at the 5-week childcare visit, and 1.12 (95% CI = 1.09 to 1.14) at the 5-year childcare visit. For children of mothers with recent depression, the RR was 1.07 (95% CI = 1.03 to 1.13) at the 5-week visit, and 1.15 (95% CI = 1.13 to 1.17) at the 5-year visit. Furthermore, the risk of missing at least four of the seven childcare visits was higher for children of females with maternal depression (RR = 1.16, 95% CI = 1.13 to 1.19).ConclusionMaternal depression seems to compromise CCP attendance. These findings suggest a need for careful clinical attention to these vulnerable families, even years after a diagnosis of depression.

The purpose of this study was to determine the risk of submersion injury and drowning among children with epilepsy and to define further specific risk factors. In a population-based retrospective cohort study the authors identified and reviewed records of all 0- through 19-year-old residents of King County Washington, who suffered a submersion incident between 1974 and 1990. Children with epilepsy were compared with those without epilepsy with regard to age, sex, site of incident, supervision, outcome, and presence of preexisting handicap. Relative risks were determined using population-based estimates of epilepsy prevalence. Of 336 submersions, 21 (6%) occurred among children with epilepsy. Children with epilepsy were more likely to be greater than 5 years old (86% vs 47%) and more likely to submerge in a bathtub (38% vs 11%). The relative risk of submersion for children with epilepsy was 47 (95% confidence interval [CI] 22 to 100) in the bathtub and 18.7 (95% CI 9.8 to 35.6) in the pool. The relative risk of drowning for children with epilepsy was 96 (95% CI 33 to 275) in the bathtub and 23.4 (95% CI 7.1 to 77.1) in the pool. These data support an increased risk of submersion and drowning among children with epilepsy.

AbstractObjectiveTo evaluate if the lowest target level for glycated haemoglobin (HbA1c) of <6.5% is associated with lower risk for retinopathy and nephropathy than less tight control in children and adults with type 1 diabetes.DesignPopulation based cohort study.SettingSwedish National Diabetes Registry, 1 January 1998 to 31 December 2017.Participants10 398 children and adults with type 1 diabetes followed from diagnosis, or close thereafter, until end of 2017.Main outcome measuresRelative risk (odds ratios) for retinopathy and nephropathy for different mean levels of HbA1c.ResultsMean age of participants was 14.7 years (43.4% female), mean duration of diabetes was 1.3 years, and mean HbA1c level was 8.0% (63.4 mmol/mol). After adjustment for age, sex, duration of diabetes, blood pressure, blood lipid levels, body mass index, and smoking, the odds ratio for mean HbA1c <6.5% (<48 mmol/mol) compared with 6.5-6.9% (48-52 mmol/mol) for any retinopathy (simplex or worse) was 0.77 (95% confidence interval 0.56 to 1.05, P=0.10), for preproliferative diabetic retinopathy or worse was 3.29 (0.99 to 10.96, P=0.05), for proliferative diabetic retinopathy was 2.48 (0.71 to 8.62, P=0.15), for microalbuminuria or worse was 0.98 (0.60 to 1.61, P=0.95), and for macroalbuminuria was 2.47 (0.69 to 8.87, P=0.17). Compared with HbA1c levels 6.5-6.9%, HbA1c levels 7.0-7.4% (53-57 mmol/mol) were associated with an increased risk of any retinopathy (1.31, 1.05 to 1.64, P=0.02) and microalbuminuria (1.55, 1.03 to 2.32, P=0.03). The risk for proliferative retinopathy (5.98, 2.10 to 17.06, P<0.001) and macroalbuminuria (3.43, 1.14 to 10.26, P=0.03) increased at HbA1c levels >8.6% (>70 mmol/mol). The risk for severe hypoglycaemia was increased at mean HbA1c <6.5% compared with 6.5-6.9% (relative risk 1.34, 95% confidence interval 1.09 to 1.64, P=0.005).ConclusionsRisk of retinopathy and nephropathy did not differ at HbA1c levels <6.5% but increased for severe hypoglycaemia compared with HbA1c levels 6.5-6.9%. The risk for severe complications mainly occurred at HbA1c levels >8.6%, but for milder complications was increased at HbA1c levels >7.0%.

Loss Of A Child

Background. Some consider the loss of a child as the most stressful life event. When the death is caused by a malignancy, the parents are commonly exposed not only to their own loss, but also to the protracted physical and emotional suffering of the child. We investigated parental risk of anxiety and depression 4–9 years after the loss of a child owing to a malignancy.Method. In 2001, we attempted to contact all parents in Sweden who had lost a child due to a malignancy during 1992–1997. We used an anonymous postal questionnaire and utilized a control group of non-bereaved parents with a living child.Results. Participation among bereaved parents was 449/561 (80%); among non-bereaved 457/659 (69%). We found an increased risk of anxiety (relative risk 1·5, 95% confidence interval 1·1–1·9) and depression (relative risk 1·4, 95% confidence interval 1·1–1·7) among bereaved parents compared with non-bereaved. The risk of anxiety and depression was higher in the period 4–6 years after bereavement than in the 7–9 years period, during which the average excess risks approached zero. Psychological distress was overall higher among bereaved mothers and loss of a child aged 9 years or older implied an increased risk, particularly for fathers.Conclusions. Psychological morbidity in bereaved parents decreases to levels similar to those among non-bereaved parents 7–9 years after the loss. Bereaved mothers and parents who lose a child 9 years or older have on average an excess risk for long-term psychological distress.

ObjectiveDemand for ambulances is growing. Nevertheless, knowledge is limited regarding diagnoses and outcomes in patients receiving emergency ambulances. This study aims to examine time trends in diagnoses and mortality among patients transported with emergency ambulance to hospital.DesignPopulation-based cohort study with linkage of Danish national registries.SettingThe North Denmark Region in 2007–2014.ParticipantsCohort of 148 757 patients transported to hospital by ambulance after calling emergency services.Main outcome measuresThe number of emergency ambulance service patients, distribution of their age, sex, hospital diagnoses, comorbidity, and 1-day and 30-day mortality were assessed by calendar year. Poisson regression with robust variance estimation was used to estimate both age-and sex-adjusted relative risk of death and prevalence ratios for Charlson Comorbidity Index (CCI) to allow comparison by year, with 2007 as reference year.ResultsThe annual number of emergency ambulance service patients increased from 24.3 in 2007 to 40.2 in 2014 per 1000 inhabitants. The proportions of women increased from 43.1% to 46.4% and of patients aged 60+ years from 39.9% to 48.6%, respectively. The proportion of injuries gradually declined, non-specific diagnoses increased, especially the last year. Proportion of patients with high comorbidity (CCI≥3) increased from 6.4% in 2007 to 9.4% in 2014, corresponding to an age- and sex-adjusted prevalence ratio of 1.27 (95% CI 1.16 to 1.39). The 1-day and 30 day mortality decreased from 2.40% to 1.21% and from 5.01% to 4.36%, respectively, from 2007 to 2014, corresponding to age-adjusted and sex-adjusted relative risk of 0.43 (95% CI 0.37 to 0.50) and 0.72 (95% CI 0.66 to 0.79), respectively.ConclusionDuring the 8-year period, the incidence of emergency ambulance service patients, the proportion of women, elderly, and non-specific diagnoses increased. The level of comorbidity increased substantially, whereas the 1-day and 30-day mortality decreased.

SUMMARYIn February 2012, an outbreak of gastroenteritis was reported in school A; a successive outbreak was reported at school B. A retrospective cohort study conducted in school A showed that seasoned green seaweed with radishes (relative risk 7·9, 95% confidence interval 1·1–56·2) was significantly associated with illness. Similarly, a case-control study of students at school B showed that cases were 5·1 (95% confidence interval 1·1–24·8) times more likely to have eaten seasoned green seaweed with pears. Multiple norovirus genotypes were detected in samples from students in schools A and B. Norovirus GII.6 isolated from schools A and B were phylogenetically indistinguishable. Green seaweed was supplied by company X, and norovirus GII.4 was isolated from samples of green seaweed. Green seaweed was assumed to be linked to these outbreaks. To our knowledge, this is the first reported norovirus outbreak associated with green seaweed.

The Impact

Background: Up to 70% of patients report ongoing symptoms four weeks after hospitalisation for pneumonia, and the impact on primary care is poorly understood. Aim: To investigate the frequency of primary care consultations after hospitalisation for pneumonia, and the reasons for consultation. Design: Population-based cohort study. Setting: UK primary care database of anonymised medical records (Clinical Practice Research Datalink, CPRD) linked to Hospital Episode Statistics (HES), England. Methods: Adults with the first ICD-10 code for pneumonia (J12-J18) recorded in HES between July 2002-June 2017 were included. Primary care consultation within 30 days of discharge was identified as the recording of any medical Read code (excluding administration-related codes) in CPRD. Competing-risks regression analyses were conducted to determine the predictors of consultation and antibiotic use at consultation; death and readmission were competing events. Reasons for consultation were examined. Results: Of 56,396 adults, 55.9% (n=31,542) consulted primary care within 30 days of discharge. The rate of consultation was highest within 7 days (4.7 per 100 person-days). The strongest predictor for consultation was a higher number of primary care consultations in the year prior to index admission (adjusted sHR 8.98, 95% CI 6.42-12.55). The commonest reason for consultation was for a respiratory disorder (40.7%, n=12,840), 12% for pneumonia specifically. At consultation, 31.1% (n=9,823) received further antibiotics. Penicillins (41.6%, n=5,753) and macrolides (21.9%, n=3,029) were the commonest antibiotics prescribed. Conclusion: Following hospitalisation for pneumonia, a significant proportion of patients consulted primary care within 30 days, highlighting the morbidity experienced by patients during recovery from pneumonia.

After a COVID-19 outbreak in the Falles festival of Borriana (Spain) during March 2020, a cohort of patients were followed until October 2020 to estimate complications post-COVID-19, considering ABO blood groups (ABO). From 536 laboratory-confirmed cases, 483 completed the study (90.1%) carried by the Public Health Center of Castelló and the Emergency and Microbiology and Clinical Analysis of Hospital de la Plana Vila-real. The study included ABO determination and telephone interviews of patients. The participants had a mean age of 37.2 ± 17.1 years, 300 females (62.1%). ABO were O (41.4%), A (45.5%), B (9.1%), and AB (3.9%). We found no difference in the incidence of COVID-19 infections. A total of 159 (32.9%) patients reported one or more post-COVID-19 complications with divergent incidences after adjustment: O (32.3%), A (32.6%), B (54.1%), and AB (27.6%); B groups had more complications post-COVID-19 when compared with O group (adjusted relative risk [aRR] 95% confidence interval [CI] 1.68, 95% CI 1.24–2.27), and symptoms of fatigue (1.79, 95% CI 1.08–2.95), myalgia (2.06, 95% CI 1.10–3.84), headache (2.61, 95% CI 1.58–4.31), and disorder of vision (4.26 95% CI 1.33–13.60). In conclusion, we observed significant differences in post-COVID-19 complications by ABO, with a higher incidence in B group. Additional research is justified to confirm our results.

ABSTRACTOBJECTIVETo examine the association between maternal and child gluten intake and risk of type 1 diabetes in children.DESIGNPregnancy cohortSETTINGPopulation-based, nation-wide study in NorwayPARTICIPANTS86,306 children in The Norwegian Mother and Child Cohort Study born from 1999 through 2009, followed to April 15, 2018.MAIN OUTCOME MEASURESClinical type 1 diabetes, ascertained in a nation-wide childhood diabetes registry. Hazard ratios were estimated using Cox regression for the exposures maternal gluten intake up to week 22 of pregnancy and child’s gluten intake when the child was 18 months old.RESULTSDuring a mean follow-up of 12.3 years (range 0.7-16.0), 346 children (0.4%) developed type 1 diabetes (incidence rate 32.6 per 100,000 person-years). The average gluten intake was 13.6 grams/day for mothers during pregnancy, and 8.8 grams/day for the child at 18 months of age. Maternal gluten intake in mid-pregnancy was not associated with the development of type 1 diabetes in the child (adjusted hazard ratio 1.02 (95% confidence interval 0.73 to 1.43) per 10 grams/day increase in gluten intake). However, the child’s gluten intake at 18 months of age was associated with an increased risk of later developing type 1 diabetes (adjusted hazard ratio 1.46 (95% confidence interval 1.06 to 2.01) per 10 grams/day increase in gluten intake).CONCLUSIONSThis study suggests that the child’s gluten intake at 18 months of age, and not the maternal intake during pregnancy, could increase the risk of type 1 diabetes in the child.WHAT IS ALREADY KNOWN ON THIS TOPICA national prospective cohort study from Denmark found that a high maternal gluten intake during pregnancy could increase the risk of type 1 diabetes in the offspring (adjusted hazard ratio 1.31 (95% confidence interval 1.001 to 1.72) per 10 grams/day increase in gluten intake). No studies have investigated the relation between the amount of gluten intake by both the mother during pregnancy and the child in early life and risk of developing type 1 diabetes in childhood.WHAT THIS STUDY ADDSIn this prospective population-based pregnancy cohort with 86,306 children of whom 346 developed type 1 diabetes we found that the child’s gluten intake at 18 months of age was associated with the risk of type 1 diabetes (adjusted hazard ratio 1.46 (95% confidence interval 1.06 to 2.01) per 10 grams/day increase in gluten intake). This study suggests that the child’s gluten intake at 18 months of age, and not the maternal intake during pregnancy, could increase the child’s risk of type 1 diabetes.
