Preterm birth and psychiatric medication prescription in young adulthood: a Swedish national cohort study.

BACKGROUND: Recent studies suggest an increased risk of adverse mental health outcomes among young adults who were born preterm. These studies have been based mainly on hospital data, thus missing large numbers of mental health problems that do not require inpatient treatment. We used national outpatient and inpatient pharmacy data to evaluate whether individuals who were born preterm were more li

Spectral asymptotics for higher-order ordinary differential equations

This paper gives one-term componentwise asymptotics for the M and spectral matrices of a self-adjoint realisation of an even-order ordinary differential expression. The underlying interval is assumed to have at least one regular endpoint, and the boundary conditions are supposed to be separated. Furthermore, the weight function and the reciprocal of the highest-order coefficient are supposed to be

Central projections of the sensory innervation of the rat middle meningeal artery.

Headaches, especially migraine, involve not only pain but also aspects such as vasodilation of cranial vessels and sensitization of nerve endings, processes dependent on and connected to the central nervous system. To understand pathogenic mechanisms of headache, it is important to elucidate the central projections of sensory nerves that innervate cranial vessels, of which the middle meningeal art

Sexual Function in Men Treated for Testicular Cancer.

ABSTRACT Introduction. Testicular germ cell cancer (TGCC) patients may be at risk of developing sexual dysfunction after treatment. Aim. The aim of this study was to assess the prevalence of sexual dysfunctions in TGCC patients 3 to 5 years after treatment, and relate findings to biochemical hypogonadism, treatment intensity, and the expected prevalence in the Swedish male population. Methods. A q

Generation of attosecond pulses in macroscopic media

We describe theoretically the generation of ultrashort (subfemtosecond) pulses using high-order harmonics of a laser pulse with a time-dependent degree of ellipticity. The single-atom response is calculated by using a low-frequency strong-field approximation. Propagation effects are taken into account using a method going beyond the slowly varying envelope approximation. Propagation modifies signi

Risk factors for a contralateral anterior cruciate ligament injury.

Contralateral anterior cruciate ligament (ACL) injuries are together with the risk of developing osteoarthritis of the knee and the risk of re-rupture/graft failure important aspects to consider after an ACL injury. The aim of this review was to perform a critical analysis of the literature on the risk factors associated with a contralateral ACL injury. A better understanding of these risk factors

Captopril suppression: Limitations for confirmation of primary aldosteronism.

INTRODUCTION: : The aldosterone/renin ratio (ARR) is the first line screening test for primary aldosteronism (PA). However, in hypertensive patients with an increased ARR, PA needs to be confirmed by other means. METHODS: : A 25 mg oral captopril test was performed in 16 healthy subjects to obtain reference values for aldosterone and ARR at 120 minutes after the test. Subsequently these data were

Socioeconomic and clinical factors explaining the risk of unstructured antiretroviral therapy interruptions among Kenyan adult patients.

A cross-sectional study was conducted to assess the extent of unstructured HIV treatment interruptions (TIs) and investigate the effects of socioeconomic, socio-demographic, HIV treatment-related and clinical factors on the magnitude and rate of the same among adult patients at a Kenyan regional referral center. Four hundred and twenty-one adult patients actively receiving antiretroviral therapy a

Hand function tests are important and sensitive tools for assessment of treatment response in patients with rheumatoid arthritis.

Objectives: To assess the usefulness of hand function measurements in a study of treatment effects of tumour necrosis factor (TNF) blockers and to define the relationship between different hand function tests and also relate hand function to general disability and disease activity. Methods: The study group consisted of 49 patients with established rheumatoid arthritis (RA) who were followed for 1

The MDM2 SNP309 G allele is not preferentially amplified in bone and soft tissue tumors.

The transcriptional enhancer region in intron 1 of the proto-oncogene MDM2 contains a polymorphic site (SNP309) that may harbor a G or a T nucleotide. Previous studies have shown that the G allele confers a higher affinity for the Sp1 transcription factor, resulting in an increased transcriptional activity of MDM2. A constitutional G allele has also been associated with earlier onset of various ca

Adjuvant tamoxifen in breast cancer patients affects the endometrium by time, an effect remaining years after end of treatment and results in an increased frequency of endometrial carcinoma.

Tamoxifen is the most used adjuvant drug in breast cancer treatment. Its main action is as an anti-oestrogen, but in the endometrium of some patients it acts as an oestrogen. Some investigators have even reported an increased risk of developing endometrial carcinoma. The question of how to follow-up these patients and how to identify patients at risk of developing endometrial premalignant changes

VWF/FVIII complex and the management of patient with inhibitors: from laboratory to clinical practice.

We and others have previously shown that inhibitor containing plasma from patients with congenital haemophilia A sometimes reacts less with von Willebrand factor (VWF) containing concentrates compared with highly purified plasma-derived or recombinant factor VIII (FVIII) concentrates. To further substantiate the haemostatic role of a variation in inhibitor reactivity with different FVIII concentra

Fathers' sense of security during the first postnatal week-A qualitative interview study in Sweden.

BACKGROUND: father's sense of security in the early postnatal period is important for the whole family. An instrument, which measures Parents' Postnatal Sense of Security (the PPSS instrument), is under development. OBJECTIVE: to explore and describe factors, which influence fathers' sense of security during the first postnatal week. METHODS: an explorative design with a qualitative approach was u

Two new species of Caloplaca from Tadjikistan, Central Asia

Two new species of Caloplaca are described, C. pseudocitrina (in the C. citrina group), which is characterized by rather long spores with a thin septum, and a squamulose thallus and C. akbarica (C. saxicola-group) characterized by rather thick, brightly yellowish pruinose apothecia and a paraplectenchymatous proper exciple. The characters of the new species and their closely allied taxa are compar

Second-harmonic generation of 405-nm light using periodically poled ${KT}i{OPO}_4$ pumped by external-cavity laser diode with double grating feedback

A frequency-doubled laser diode system for generation of blue-UV light is described. The system is based on an external-cavity high-power laser diode with double feedback from the zeroth and the first orders of a diffraction grating. Light at 405 nm is generated in a single-pass configuration using periodically poled KTiOPO4. We show that the double grating feedback improves the second harmonic co

Applications of lentiviral vectors for biology and gene therapy of neurological disorders.

Recombinant lentiviral vectors (rLV) are powerful tools for gene transfer to the central nervous system (CNS) and hold great potential as a therapeutic gene therapy strategy for neurological disorders. Recent data indicate that rLVs are suitable for functional studies in the CNS by over expression or knock down of specific proteins. Based on a variety of lentiviruses species, different vector syst
