A high fat to vitamin E ratio in the feed protects and improves uptake of the natural form of vitamin E in postweaning calves.

In postweaning calves, it is a challenge to maintain the plasma vitamin E level at or above the recommended level (3 µg/mL), which is linked to a good immune response. It has been unclear until now why the provision of solid feed with concentrations below 200 mg/kg feed of vitamin E is ineffective in maintaining the plasma vitamin E level of calves above the recommended plasma level postweaning. The present study was conducted to investigate if a high fat to vitamin E ratio in the concentrate could protect and improve the delivery of the natural form of vitamin E (RRR-α-tocopherol) to calves postweaning.

Chronic care services and variation between Danish general practices: a nationwide cohort study.

Background: Little is known about variations in the provision of chronic care services in primary care.

Aim: To describe the frequency of chronic care services provided by GPs and analyse the extent of non-random variation in service provision.

Design And Setting: Nationwide cohort study undertaken in Denmark using data from 2016.

Invited review: Freedom from thirst-Do dairy cows and calves have sufficient access to drinking water?

The importance of drinking water for production and animal welfare is widely recognized, but surveys and animal welfare assessment schemes suggest that many dairy calves and dairy cows do not have sufficient access. Limit milk-fed calves drink more water than calves fed milk ad libitum, but ad libitum milk-fed calves also require access to drinking water, as milk does not meet the animal's requirement for water. At hot ambient temperatures and when calves are sick, access to water is especially important and should be provided at all times.

Associations of Lifestyle and Anthropometric Factors With the Risk of Herpes Zoster: A Nationwide Population-Based Cohort Study.

The role of lifestyle in development of herpes zoster remains unclear. We examined whether smoking status, alcohol consumption, body mass index, or physical activity were associated with zoster risk. We followed a population-based cohort of 101,894 respondents to the 2010 Danish National Health Survey (baseline, May 1, 2010) until zoster diagnosis, death, emigration, or July 1, 2014, whichever occurred first.

Advanced Access scheduling in general practice and use of primary care: a Danish population-based matched cohort study.

Background: Advanced access scheduling (AAS) allows patients to receive care from their GP at the time chosen by the patient. AAS has shown to increase the accessibility to general practice, but little is known about how AAS implementation affects the use of in-hours and out-of-hours (OOH) services.

Aim: To describe the impact of AAS on the use of in-hours and OOH services in primary care.

The effect of milk feeding strategy and restriction of meal patterning on behavior, solid feed intake, and growth performance of male dairy calves fed via computer-controlled milk feeders.

Dairy calves are often offered milk allowance at a flat rate during the first 6 wk of life, although an initial high allowance followed by a stepwise reduction (step-down strategy) may correspond better to the calves' nutritional needs. The amount of milk offered per feeding is typically constant. However, during natural suckling, the daily number of milk meals (suckling frequency) declines with age, which may reflect increased consumption of solid feeds.

Association between Mental Disorders and Subsequent Medical Conditions.

Background: Persons with mental disorders are at a higher risk than the general population for the subsequent development of certain medical conditions.

Methods: We used a population-based cohort from Danish national registries that included data on more than 5.9 million persons born in Denmark from 1900 through 2015 and followed them from 2000 through 2016, for a total of 83.

Statins and Risk of Intracerebral Hemorrhage in Individuals With a History of Stroke.

Background and Purpose- It has been suggested that statins increase the risk of intracerebral hemorrhage in individuals with a history of stroke, which has led to a precautionary principle of avoiding statins in patients with prior intracerebral hemorrhage. However, such prescribing reticence may be unfounded and potentially harmful when considering the well-established benefits of statins. This study is so far the largest to explore the statin-associated risk of intracerebral hemorrhage in individuals with prior stroke.

Risk of diabetic complications and subsequent mortality among individuals with schizophrenia and diabetes - a population-based register study.

Background: Individuals with schizophrenia often develop diabetes, but little is known about their risk of diabetic complications. We aimed to study incidence of registered diabetic complications and subsequent mortality in individuals with schizophrenia and diabetes compared to individuals with diabetes only.

Methods: We conducted a cohort study using nationwide registers and followed all individuals in the entire Danish population diagnosed with diabetes from 1997 to 2017.

Selective serotonin reuptake inhibitors and risk of epilepsy after traumatic brain injury - A population based cohort study.

Objective: Traumatic brain injury (TBI) is common and associated with a marked increased risk of developing epilepsy. Animal studies indicate that treatment with selective serotonin reuptake inhibitors (SSRIs) may increase the risk of epilepsy after TBI. The aim of this study was to investigate whether use of SSRIs modifies the risk of epilepsy after TBI.

Statins and Risk of Intracerebral Haemorrhage in a Stroke-Free Population: A Nationwide Danish Propensity Score Matched Cohort Study.

Background: Statins may increase the risk of intracerebral haemorrhage (ICH) in individuals with previous stroke. It remains unclear whether this applies to individuals with no history of stroke. This study is the first to explore the statin-associated risk of ICH in stroke-free individuals while considering the timing of statin initiation.

Maternal bereavement shortly before or during pregnancy and risk of postpartum psychotic illness: a population-based study from Denmark and Sweden.

Postpartum psychosis is a rare but severe complication following childbirth, with unknown etiology. This study investigated whether the death of a close family member - a source of severe stress - the year before or during pregnancy was associated with an increased risk of psychotic illness in the postpartum period among women without and with a history of psychiatric disorder. We studied live births in Denmark during 1978-2008 and births in Sweden during 1973-2006 (n=5,246,978).

Premature mortality in persons with epilepsy and schizophrenia: A population-based nationwide cohort study.

Objective: To determine the mortality for persons with epilepsy and schizophrenia by absolute and relative measures.

Methods: This is a population-based nationwide cohort study of persons born in Denmark from 1960 to 1987 who were alive and residing in Denmark on their 25th birthday. We identified persons diagnosed with epilepsy and schizophrenia prior to their 25th birthday and followed them to death, emigration, or December 31, 2012, whichever came first.

Depression, antidepressants, and the risk of non-valvular atrial fibrillation: A nationwide Danish matched cohort study.

Background: Depression is associated with an increased risk of a series of cardiovascular diseases and with increased symptom burden in patients with atrial fibrillation. The aim of this study was to determine the association between depression as well as antidepressant treatment and the risk of incident atrial fibrillation.

Design: A nationwide register-based study comparing the atrial fibrillation risk in all Danes initiating antidepressant treatment from 2000 to 2013 ( N = 785,254) with that in a 1:5-matched sample from the general population.

Correction to: Impact of socioeconomic position and distance on mental health care utilization: a nationwide Danish follow-up study.

In the original publication of this article, Table 3 was published incorrectly. The corrected table is shown below.

[Mental-physical multimorbidity].

Mental-physical multimorbidity is highly prevalent and challenges the conventional thinking of the single disease paradigm in healthcare systems. Mental and physical health are closely related in a bidirectional manner. Persons with mental-physical multimorbidity experience a heavy symptom and treatment burden in addition to a lower quality of life and an impaired medical prognosis.

Long-term risk of dementia among people with traumatic brain injury in Denmark: a population-based observational cohort study.

Background: Traumatic brain injury (TBI) has been associated with increased risk of dementia; however, large-scale studies with long follow-up have been scarce. We investigated the association between TBI, including severity and number of TBIs, and the subsequent long-term risk of dementia.

Methods: We did a nationwide population-based observational cohort study in Denmark using information on citizens from national registries.

Association between perceived stress, multimorbidity and primary care health services: a Danish population-based cohort study.

Objectives: Mental stress is common in the general population. Mounting evidence suggests that mental stress is associated with multimorbidity, suboptimal care and increased mortality. Delivering healthcare in a biopsychosocial context is key for general practitioners (GPs), but it remains unclear how persons with high levels of perceived stress are managed in primary care.

Use of primary healthcare for persons with epilepsy.

Introduction: In Denmark, care and treatment related to epilepsy primarily takes place at specialized hospital departments (neurology and pediatrics). The general practitioner (GP) in contrast is the primary contact and acts as a gatekeeper to the healthcare system for other disorders. The aim of the present study was to describe the utilization of services provided by the GP for children with epilepsy before and after diagnosis of epilepsy and to compare it with that of children without epilepsy.

Attendance of routine childcare visits in primary care for children of mothers with depression: a nationwide population-based cohort study.

Background: Depression 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.

Aim: To 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.

Use of general practice before and after mild traumatic brain injury: a nationwide population-based cohort study in Denmark.

Objectives: Traumatic brain injury (TBI) is commonly seen in the emergency department (ED). Approximately 85%-90% of TBIs are mild (mTBI). Some cause symptoms such as headache, dizziness, anxiety, blurred vision, insomnia and concentration difficulties, collectively known as postconcussion syndrome (PCS).
