CIRC - "Rate-Control Treatment and Mortality in Atrial Fibrillation"
"Rate-Control Treatment and Mortality in Atrial Fibrillation"
"Conclusions—In this nationwide atrial fibrillation cohort, the risk of mortality was lower for patients receiving rate-control treatment with β-blockers or calcium channel blockers, and the use of β-blockers was associated with the largest risk reduction. Digoxin use was associated with greater mortality. Prospective, randomized trials are necessary to confirm these findings."

"Risk of cancer from occupational exposure to ionising radiation: retrospective cohort study of workers in France, the United Kingdom, and the United States (INWORKS)"
"What this study adds The study provides a direct estimate of the association between protracted low dose exposure to ionising radiation and solid cancer mortality. Although high dose rate exposures are thought to be more dangerous than low dose rate exposures, the risk per unit of radiation dose for cancer among radiation workers was similar to estimates derived from studies of Japanese atomic bomb survivors. Quantifying the cancer risks associated with protracted radiation exposures can help strengthen the foundation for radiation protection standards."

NEJM - "A Randomized, Controlled Trial of Total Knee Replacement"
"CONCLUSIONS
"CONCLUSIONS
In patients with knee osteoarthritis who were eligible for unilateral total knee replacement, treatment with total knee replacement followed by nonsurgical treatment resulted in greater pain relief and functional improvement after 12 months than did nonsurgical treatment alone. However, total knee replacement was associated with a higher number of serious adverse events than was nonsurgical treatment, and most patients who were assigned to receive nonsurgical treatment alone did not undergo total knee replacement before the 12-month follow-up. (Funded by the Obel Family Foundation and others; MEDIC ClinicalTrials.gov number, NCT01410409.)"

JAMA - (REVIEW) "Evaluation and Treatment of Pericarditis A Systematic Review"
JAMA - (REVIEW) "Evaluation and Treatment of Pericarditis A Systematic Review"
"Findings The etiology of pericarditis may be infectious (eg, viral and bacterial) or noninfectious (eg, systemic inflammatory diseases, cancer, and post–cardiac injury syndromes). Tuberculosis is a major cause of pericarditis in developing countries but accounts for less than 5% of cases in developed countries, where idiopathic, presumed viral causes are responsible for 80% to 90% of cases. The diagnosis is based on clinical criteria including chest pain, a pericardial rub, electrocardiographic changes, and pericardial effusion. Certain features at presentation (temperature >38°C [>100.4°F], subacute course, large effusion or tamponade, and failure of nonsteroidal anti-inflammatory drug [NSAID] treatment) indicate a poorer prognosis and identify patients requiring hospital admission. The most common treatment for idiopathic and viral pericarditis in North America and Europe is NSAID therapy. Adjunctive colchicine can ameliorate the initial episode and is associated with approximately 50% lower recurrence rates. Corticosteroids are a second-line therapy for those who do not respond, are intolerant, or have contraindications to NSAIDs and colchicine. Recurrences may occur in 30% of patients without preventive therapy.

Recurrences may occur in 30% of patients without preventive therapy.
Conclusions and Relevance Pericarditis is the most common form of pericardial disease worldwide and may recur in as many as one-third of patients who present with idiopathic or viral pericarditis. Appropriate triage and treatment with NSAIDs may reduce readmission rates for pericarditis. Treatment with colchicine can reduce recurrence rates."

Scientists, blinded to retraction status and with no specialist skill in the field, identify significantly more discrepancies in retracted than unretracted reports of clinical trials. Discrepancies could be an early and accessible signal of unreliability in clinical trial reports."
