Development of a prognostic model of COVID-19 severity: a population-based cohort study in Iceland.

Background: The severity of SARS-CoV-2 infection varies from asymptomatic state to severe respiratory failure and the clinical course is difficult to predict. The aim of the study was to develop a prognostic model to predict the severity of COVID-19 in unvaccinated adults at the time of diagnosis.

Methods: All SARS-CoV-2-positive adults in Iceland were prospectively enrolled into a telehealth service at diagnosis.

The Current State of Neurosurgery in Iceland.

Background: Although surgical conditions account for 32% of the global burden of diseases, approximately 5 billion people worldwide lack access to timely and affordable, surgical and anesthetic services. Disparities in access to surgical care are most evident in low- and middle-income countries, often resulting from a lack of surgical infrastructure. However, the establishment of surgical infrastructure, particularly for specialty surgical services including neurosurgery, is challenging in countries with small populations, irrespective of income classification, due to the distribution of high costs among a lesser number of individuals.

Monoclonal gammopathy of undetermined significance and COVID-19: a population-based cohort study.

Multiple myeloma (MM) patients have increased risk of severe coronavirus disease 2019 (COVID-19) when infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Monoclonal gammopathy of undetermined significance (MGUS), the precursor of MM has been associated with immune dysfunction which may lead to severe COVID-19. No systematic data have been published on COVID-19 in individuals with MGUS.

Outpatient Use of Antimicrobials in Patients With Rheumatoid Arthritis Before and After Treatment With Tumor Necrosis Factor Inhibitors: A Nationwide Retrospective Cohort Study.

Objective: The objective of this study was to investigate the effect of tumor necrosis factor α inhibitor (TNFi) initiation on the use of antimicrobials among biologic-naïve patients with rheumatoid arthritis (RA).

Methods: Information on all biologic-naïve patients with RA was extracted from ICEBIO, a nationwide registry. Each patient was matched on age, sex, and calendar time to five randomly selected individuals from the general population.

[Critical care management of patients with spontaneous subarachnoid haemorrhage - a review].

Spontaneous subarachnoid haemorrhage is characterized by extravasation of blood into the subarachnoid space without a preceding trauma. The leading cause is a ruptured intracranial aneurysm. Serious neurologic complications can occur, such as rebleeding, cerebral vasospasm and delayed cerebral ischemia.

[Obesity isn't always obesity: Cushing's disease - case report].

Woman in her thirties presented to the emergency room with a two-week history of worsening headache and diplopia. For eight years she had suffered from progressive weight gain, diabetes and hypertension that didn't improve with lifestyle modification. A lumbar puncture demonstrated increased intracranial pressure and MRI a pituitary adenoma.

[First case of COVID-19 treated with tocilizumab in Iceland].

A gentleman in his early fifties became ill with flu-like symptoms after vacationing abroad and was diagnosed with COVID-19 after returning to Iceland. A few days later he was admitted to the University Hospital, Landspitali, due to worsening respiratory symptoms and severe fatigue. A computed tomography scan of lthe lungs showed diffuse bilateral consolidations and ground glass changes.

Sequence variant at 8q24.21 associates with sciatica caused by lumbar disc herniation.

Lumbar disc herniation (LDH) is common and often debilitating. Microdiscectomy of herniated lumbar discs (LDHsurg) is performed on the most severe cases to resolve the resulting sciatica. Here we perform a genome-wide association study on 4,748 LDHsurg cases and 282,590 population controls and discover 37 highly correlated markers associating with LDHsurg at 8q24.

A clinical decision support system for the diagnosis, fracture risks and treatment of osteoporosis.

Expanding medical knowledge increases the potential risk of medical errors in clinical practice. We present, OPAD, a clinical decision support system in the field of the medical care of osteoporosis. We utilize clinical information from international guidelines and experts in the field of osteoporosis.
