Background: Surgical treatment of pituitary lesions causing hormonal overproduction or mass effect is standard procedure. There are few reports on the results and complications related to these surgeries from Northern Europe. Our aim was to evaluate the outcome and complications of a single tertiary surgical center over more than a decade.

Autoimmune Addison's disease (AAD) is characterized by the autoimmune destruction of the adrenal cortex. Low prevalence and complex inheritance have long hindered successful genetic studies. We here report the first genome-wide association study on AAD, which identifies nine independent risk loci (P < 5 × 10).

Background: Hydrocortisone treatment in transsphenoidal pituitary surgery has been debated. Although several publications advocate restrictive treatment, centers around the world administer stress doses of hydrocortisone in patients with presumed intact cortisol production. Our aim with this analysis was to compare postoperative hypocortisolism in patients who received three different protocols of hydrocortisone therapy during and after surgery.

Article Synopsis
  • Autoimmune Addison's disease (AAD) is the main cause of primary adrenal failure, and while it has high heritability, its rarity has limited genetic research to candidate-gene studies.
  • A comprehensive study investigated risk loci and over 1800 candidate genes in 479 AAD patients and 2394 controls, confirming some previous risk variants while disproving others.
  • The research identified a new risk locus in the autoimmune regulator gene (AIRE) and highlighted that the known risk loci only account for about 7% of the genetic risk for AAD in the population studied.

Background: Early detection of autoimmune Addison's disease (AAD) is important as delay in diagnosis may result in a life-threatening adrenal crisis and death. The classical clinical picture of untreated AAD is well-described, but methodical investigations are scarce.

Objective: Perform a retrospective audit of patient records with the aim of identifying biochemical markers for early diagnosis of AAD.

Context: Autoimmune polyendocrine syndrome type 1 (APS1) is a monogenic disorder that features autoimmune Addison disease as a major component. Although APS1 accounts for only a small fraction of all patients with Addison disease, early identification of these individuals is vital to prevent the potentially lethal complications of APS1.

Objective: To determine whether available serological and genetic markers are valuable screening tools for the identification of APS1 among patients diagnosed with Addison disease.

Background: Provisia™ rice (PV), a non-genetically engineered (GE) quizalofop-resistant rice, will provide growers with an additional option for weed management to use in conjunction with Clearfield rice (CL) production. Modeling compared the impact of stacking resistance traits versus single traits in rice on introgression of the resistance trait to weedy rice (also called red rice). Common weed management practices were applied to 2-, 3- and 4-year crop rotations, and resistant and multiple-resistant weedy rice seeds, seedlings and mature plants were tracked for 15 years.

Article Synopsis
  • Roughstalk bluegrass is a problematic weed in Oregon's cool season grass seed fields, particularly in waterlogged areas.
  • A study showed that roughstalk bluegrass exhibited different root development and respiration compared to tall fescue when subjected to waterlogging, with roughstalk bluegrass developing a shallower root system.
  • Despite both species facing reduced turf quality and biomass from waterlogging, roughstalk bluegrass demonstrated better tolerance due to its unique root characteristics and fermentation rates.

Acromegaly is a rare disorder caused by chronic growth hormone (GH) hypersecretion. While diagnostic and therapeutic methods have advanced, little information exists on trends in acromegaly characteristics over time. The , a relational database, is designed to assess the profile of acromegaly patients at diagnosis and during long-term follow-up at multiple treatment centers.

Context: Studies of the clinical and immunological features of autoimmune Addison disease (AAD) are needed to understand the disease burden and increased mortality.

Objective: To provide upgraded data on autoimmune comorbidities, replacement therapy, autoantibody profiles, and cardiovascular risk factors.

Design, Setting, And Participants: A cross-sectional, population-based study that included 660 AAD patients from the Swedish Addison Registry (2008-2014).

Background: Autoimmune disease is one of the leading causes of morbidity and mortality worldwide. In Addison's disease, the adrenal glands are targeted by destructive autoimmunity. Despite being the most common cause of primary adrenal failure, little is known about its aetiology.

In this article, we review published studies covering epidemiology, natural course and mortality in primary adrenal insufficiency (PAI) or Addison's disease. Autoimmune PAI is a rare disease with a prevalence of 100-220 per million inhabitants. It occurs as part of an autoimmune polyendocrine syndrome in more than half of the cases.

Context: Conventional glucocorticoid replacement therapy in patients with Addison's disease (AD) is unphysiological with possible adverse effects on mortality, morbidity and quality of life. The diurnal cortisol profile can likely be restored by continuous subcutaneous hydrocortisone infusion (CSHI).

Objective: The aim of this study was to compare circadian hormone rhythms and insulin sensitivity in conventional thrice-daily regimen of glucocorticoid replacement therapy with CSHI treatment in patients with AD.

Background: Gene variants known to contribute to Autoimmune Addison's disease (AAD) susceptibility include those at the MHC, MICA, CIITA, CTLA4, PTPN22, CYP27B1, NLRP-1 and CD274 loci. The majority of the genetic component to disease susceptibility has yet to be accounted for.

Aim: To investigate the role of 19 candidate genes in AAD susceptibility in six European case-control cohorts.

Context: Conventional glucocorticoid replacement therapy fails to mimic the physiological cortisol rhythm, which may have implications for morbidity and mortality in patients with Addison's disease.

Objective: The objective of the study was to compare the effects of continuous sc hydrocortisone infusion (CSHI) with conventional oral hydrocortisone (OHC) replacement therapy.

Design, Patients, And Interventions: This was a prospective crossover, randomized, multicenter clinical trial comparing 3 months of treatment with thrice-daily OHC vs CSHI.

Primary adrenal insufficiency (PAI), or Addison's disease, is a rare, potentially deadly, but treatable disease. Most cases of PAI are caused by autoimmune destruction of the adrenal cortex. Consequently, patients with PAI are at higher risk of developing other autoimmune diseases.

Article Synopsis
  • Multiple-herbicide resistance in Lolium perenne spp. multiflorum has developed in Oregon, particularly in a population found in a Christmas tree plantation, requiring a better understanding of its resistance patterns.
  • The CT population was found to be resistant to at least six herbicides through different mechanisms, with two specific genetic mutations identified, but no known mutations associated with glyphosate resistance were present.
  • The study emphasizes that while managing multiple-herbicide-resistant populations can be complex, it's possible to integrate remaining chemical control methods with non-chemical strategies to help mitigate the issue in agricultural settings.

Galanin, a 29-aminoacid peptide (30 in humans), is widely distributed in the nervous and endocrine systems and exerts its actions via three G-protein-coupled receptors, GalR1-3. The galanin system has, among others, been associated with tumorigenesis. Our objective was to assess the expression of galanin and its receptors in pituitary tumors.
