  • Smartphone sensor data has potential to detect cannabis intoxication
    26 Tháng 9 2021
    A smartphone sensor, much like what is used in GPS systems, might be a way to determine whether or not someone is intoxicated after consuming marijuana, according to a new study.
  • When it comes to communication skills, maybe we’re born with it?
    25 Tháng 9 2021
    A neuroscientist and speech pathologist, led a study that uncovered how neural networks in infants influence their language learning skills in early childhood.
  • In a gene tied to growth, scientists see glimmers of human history
    25 Tháng 9 2021
    A new study delves into the evolution and function of the human growth hormone receptor gene, and asks what forces in humanity's past may have driven changes to this vital piece of DNA.
  • Guiding microbes along their path
    24 Tháng 9 2021
    The direction of movement of a microbe directly depends on the curvature of its environment, according to new findings. The researchers investigated the navigation of a model microbe, a small self-propelling microalga, in confined compartments with different shapes. They also developed theoretical models to predict the probability flux of that microswimmer which was confirmed by experiments. With this model available, it is now possible to pre-define the average trajectory of such microbes by manipulating the curvature of the compartments which directly affects their movement.
  • Insights from our genome and epigenome will help prevent, diagnose and treat cancer
    24 Tháng 9 2021
    In 2020, an estimated 10 million people lost their lives to cancer. This devastating disease is underpinned by changes to our DNA -- the instruction manual for all our cells.

  • Role of transthoracic echocardiogram in acute heart failure
    26 Tháng 9 2021
    Acute Heart Failure (AHF) is an increasingly common condition with a poor prognosis. In contrast to CHF where advances in medical therapy and devices has led to significant improvement in morbidity and mortality, the prognosis for AHF has not changed significantly in the last few decades despite efforts to find effective treatment. There are multiple factors that contribute to the high mortality and morbidity of AHF; it can be a diagnostic challenge, determining whether decongestion has been...
  • The 'diamond' approach to personalized drug treatment of heart failure with reduced ejection fraction
    26 Tháng 9 2021
    Heart failure (HF) is a complex clinical syndrome with symptoms and signs due to cardiac dysfunction, leading to high hospitalization and morbidity. HF treatment has rapidly developed in recent decades, and breakthroughs have been made. Although conventional neurohormonal blockade therapies, including β-blockers, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), and mineralocorticoid receptor antagonists (MRAs), significantly improve the prognosis of patients...
  • Infrastructure, logistics and clinical practice management of acute trauma hemorrhage and coagulopathy: a survey across German trauma centers
    26 Tháng 9 2021
    CONCLUSION: This survey confirms still existing differences in infrastructure, logistics and clinical practice management for the detection of acute trauma hemorrhage and coagulopathy amongst DGU^(®)-certified supraregional, regional and local trauma centers. Further work is recommended to locally implement diagnostics, therapies and treatment algorithms compliant to current guidelines to ensure the best possible outcomes in bleeding trauma patients.
  • Can buccal infiltration of articaine replace traditional inferior alveolar nerve block for the treatment of mandibular molars in pediatric patients? A systematic review and meta-analysis
    26 Tháng 9 2021
    CONCLUSIONS: Evidence suggests that buccal infiltration of articaine is a viable alternative to IANB with lignocaine in pediatric patients for treating mandibular molars. Based on the confidence intervals, there may be a tendency of higher success rates with buccal infiltration of articaine.
  • The Use of β-Blockers in Heart Failure with Reduced Ejection Fraction
    26 Tháng 9 2021
    Treatment with β-blockers is the main strategy for managing patients with heart failure and reduced ejection fraction because of their ability to reverse the neurohumoral effects of the sympathetic nervous system, with consequent prognostic and symptomatic benefits. However, to date, they are underused, mainly because of the misconception that hypotension and bradycardia may worsen the haemodynamic status of patients with HFrEF and because of the presence of comorbidities falsely believed to be...

  • Incorrect Group Sizes in Figure
    21 Tháng 9 2021
    In the US Preventive Services Task Force report titled “Counseling and Behavioral Interventions for Healthy Weight and Weight Gain in Pregnancy: Evidence Report and Systematic Review for the US Preventive Services Task Force,” published in the May 25, 2021, issue of JAMA, group sizes appeared incorrectly in a figure. In the “Obese” section of Figure 3, in the row reporting data for the study by Daly et al, the number of participants in the treatment group should have been 34, rather than 33, and the number in the control group should have been 42, rather than 36. This article was corrected online.
  • Transcatheter Valve Replacement for Bicuspid Aortic Stenosis
    21 Tháng 9 2021
    Bicuspid aortic valve (BAV) disease is a congenital condition that affects an estimated 1% of the world’s population. While initial valve function is relatively normal and has little early clinical consequence, progressive valve fibrosis and calcification eventually results in severe aortic stenosis, requiring aortic valve replacement in nearly all patients with BAV in later life.
  • A Reporting Guideline for Mediation Analyses
    21 Tháng 9 2021
    In this issue of JAMA, Lee et al provide the results of a carefully structured, comprehensive effort to define the elements to be included in reports of studies using mediation analyses. Mediation analysis refers to a group of statistical methods for assessing the relative contributions of multiple pathways by which a treatment or risk factor may affect clinical outcomes. Mediators are quantifiable characteristics in the causal pathway through which an intervention (such as a treatment) exerts its effect. For example, if a behavioral intervention leads to reduced caloric intake, and patients lose weight as a result, then caloric intake would be a likely mediator of the effect of the behavioral intervention on weight loss. A mediation analysis evaluates the relationships between the treatment and potential mediators and, separately, between the mediators and outcomes, and quantitatively partitions the overall treatment effect among the different causal pathways. One of the causal pathways may be direct without any identified mediator.

  • Error in Additional Contributions
    24 Tháng 9 2021
    The Research Letter titled “Prevalence of SARS-CoV-2 Antibodies From a National Serosurveillance of Kenyan Blood Donors, January-March 2021,” published in the September 2, 2021, issue of JAMA, included an error in the list of members of the Kenya SARS-CoV-2 Serology Consortium. This included erroneously excluding John Gitonga and Daisy Mugo. The list of consortium members in the Additional Contributions has been updated to include all appropriate individuals. (All other information in the Additional Contributions was correct and is unchanged.)

  • Clarification of Dosing
    23 Tháng 9 2021
    In the JAMA Insights article titled “Novel Lipid-Lowering Therapies to Reduce Cardiovascular Risk,” published July 20, 2021, the dosing of inclisiran required clarification. The fourth sentence of the “Inclisiran” section that stated that inclisiran was dosed as “1 to 3 injections administered over a 3-month period, followed by dosing once every 6 months” should be replaced with “Clinical trials reveal durable 30% to 60% reductions in LDL-C.10 Inclisiran is dosed by injection at day 1 and day 90, followed by dosing once every 6 months.” This article was corrected online.
