Simultaneous Planning and Execution for Safe Flight of Quadrotors suffering One Rotor Loss and Disturbance

Safety is crucial for quadrotor flight, especially when the system suffers one rotor loss and disturbance. To enable quadrotors to survive in these worst cases, this paper proposes a Simultaneous Planning And Execution (SPAE) system strategy. First, the Euler angles under different equilibrium states are solved to ensure the feasibility of the control input when the quadrotors encounters rotor loss and disturbance. Based on the admissible Euler angle solutions, an emergency control strategy is proposed to realize desired angles by recalculating the desired trajectory and the disturbance observer. Meanwhile, this control strategy sacrifices the yaw angle control to handle further underactuation of the system caused by complete rotor failure. In addition to rotor losses, unsafe flight caused by actuator saturation is considered in the SPAE strategy where the planning and execution are simultaneous. As a decision maker, the planning considers the current disturbances and constraints of actuators, then generates a feasible trajectory for controller execution. As an executor of the decision, the controller feedback estimated disturbance information to the trajectory planning, which can help trajectory planning make admissible decisions consistent with the current situation. As a result, the actuator saturation caused by the underestimation of disturbance can be avoided under a feasible regenerated trajectory. Extensive simulations and experiments prove the validity of the proposed SPAE strategy.

Discharge Against Medical Advice in The Early Period of Inpatient Psychiatric Treatment

Objective: Some patients refuse inpatient psychiatric treatment and are discharged against medical advice in the first few days itself. Reviewing related features prior to hospitalization is vital for taking precautions related to these conditions. Materials and methods: Twenty-three patients admitted to psychiatry inpatient unit and discharged voluntarily within 72 hours were compared with a control group matched in terms of diagnosis, age, and sex, comprising patients who were hospitalized in the same period and discharged after the treatment. These two groups were compared with respect to sociodemographic and clinical characteristics, inpatient and outpatient evaluation, and treatment procedures. Results: Sociodemographic characteristics, waiting time for hospitalization, the level of compliance with outpatient treatment, the percentage of voluntary admissions, and the type of hospitalization were similar, whereas the history of hospitalization (p = .022) and administration of psychotropics in the early period of hospitalization (p = .005) were fewer in the refusal group. There was no difference in the number of the interviews made with the staff; communication of the patients with their relatives was higher in the control group (p < .001). Conclusion: Treatment refusal is associated with the post-admission procedures rather than the pre-admission practices, decision, and type of admission. Evaluation of these procedures in larger samples is important for taking necessary precautions related to discharge against medical advice.

Prognostic factors in acute poisoning with central nervous system xenobiotics: development of a nomogram predicting risk of intensive care unit admission.

Acute intoxication with central nervous system (CNS) xenobiotics is an increasing global problem. Predicting the prognosis of acute toxic exposure among patients can significantly alter the morbidity and mortality. The present study outlined the early risk predictors among patients diagnosed with acute exposure to CNS xenobiotics and endorsed bedside nomograms for identifying patients requiring intensive care unit (ICU) admission and those at risk of poor prognosis or death. This study is a 6-year retrospective cohort study conducted among patients presented with acute exposure to CNS xenobiotics. A total of 143 patients' records were included, where (36.4%) were admitted to the ICU, and a significant proportion of which was due to exposure to alcohols, sedative hypnotics, psychotropic, and antidepressants (P=0.021). ICU admission was associated with significantly lower blood pressure, pH, and HCO3 levels and higher random blood glucose (RBG), serum urea, and creatinine levels (P<0.05). The study findings indicate that the decision of ICU admission could be determined using a nomogram combining the initial HCO3 level, blood pH, modified PSS, and GCS. HCO3 level<17.1mEq/L, pH<7.2, moderate-to-severe PSS, and GCS<11 significantly predicted ICU admission. Moreover, high PSS and low HCO3 levels significantly predicted poor prognosis and mortality. Hyperglycemia was another significant predictor of mortality. Combining initial GCS, RBG level, and HCO3 is substantially helpful in predicting the need for ICU admission in acute alcohol intoxication. The proposed nomograms yielded significant straightforward and reliable prognostic outcomes predictors in acute exposure to CNS xenobiotics.

Sleep study measures on post-operative night one following expansion pharyngoplasty for obstructive sleep apnea

PurposeTo examine the changes in measures of sleep apnea severity and hypoxemia on the first post-operative night (PON1) following expansion pharyngoplasty as a means to assess the safety of same day discharge after surgery. Materials and methodsProspective cohort study of subjects with moderate-severe obstructive sleep apnea who underwent expansion pharyngoplasty at a single academic sleep surgical practice. A WatchPAT study was performed on the night immediately following surgery (PON1) and comparisons were made to baseline sleep testing. ResultsTwenty subjects who had a mean age of 45.7 ± 10.8 years old and a mean body-mass index (BMI) of 31.4 ± 3.2 kg/m2 were enrolled. Patients had baseline severe OSA with mean apnea hypopnea index (AHI) 39.4 ± 19.5/h, O2 nadir 80.8 ± 6.1 % and time with oxygen saturation below 88 % (T88) 12.3 ± 13.2 min. Measures of sleep apnea and nocturnal hypoxemia were not significantly different on PON1. AHI was increased by >20 % in 11 (55.0 %) patients. One patient demonstrated a >10 % worsening in O2 nadir, and 8 patients (45.0 %) demonstrated a >20 % worsening in T88. BMI over 32 was associated with elevated odds of worsening in T88, and anesthesia involving ketamine was associated with lower odds of a 20 % worsening in AHI or T88. ConclusionsOn PON1 following expansion pharyngoplasty, AHI and nocturnal hypoxemia are stable overall but variable on an individual basis. The decision for admission should therefore be made on a case-by-case basis. Further research is need to elucidate definitive predictors of worsening measures on PON1.

Foreign Donations in the Higher Education Sector of the United States and the United Kingdom: Pathways for Reputation Laundering

We explore how the influx of foreign funding into the higher education sectors of the United States and United Kingdom has raised the challenge of “reputation laundering”—when foreign donors and individuals use donations to prestigious universities to boost their international public image and offset negative images or reported controversies back in their home country. We outline four pathways for reputation laundering—donations for academic programs/schools, naming rights, honorary degrees and board seats; and the offer of favorable admissions decisions—and examine the variety of policies, practices and safeguards that have been adopted by U.K. and U.S. universities in response. We present evidence, drawn from a survey of U.K. development officers, that university diligence procedures, which usually focus on compliance with the law, often are inadequate for filtering or deterring most types of reputation laundering.

Prevalence of Depression and Predictors of Discharge to a Psychiatric Hospital in Young People with Hospital-Treated Deliberate Self-Poisoning at an Australian Sentinel Unit.

Hospital treated deliberate self-poisoning is common in young people. Internationally, estimates of rates of depression in this population are very wide (14.6% to 88%). The aims of this study were to determine the prevalence of depression and the independent predictors of referral for psychiatric hospitalisation in young people (aged 16 to 25 years) following an index episode of hospital treated deliberate self-poisoning. A retrospective cohort study design (n = 1410), with data drawn from a population-based clinical case register. Unadjusted and adjusted estimates of predictors of referral for psychiatric admission (after-care) used logistic regression models. Prevalence of any depression diagnosis was 35.5% (n = 500); and 25.4% (n = 358) were referred for a psychiatric admission. The adjusted estimates for predictors of psychiatric inpatient referral were: high suicidal level (OR 118.21: CI 95% 63.23-220.99), low/moderate suicidal level (14.27: 9.38-21.72), any depression (2.88: 1.97-4.22), any psychosis (4.06; 1.15-14.36), older age (1.12: 1.04-1.21), and number of support people (0.88: 0.78-0.98). Depression was diagnosed in more than a third and was an independent predictor of psychiatric inpatient referral, so service providers need to account for this level of need in the provision of assessment and after-care services. Evidence-based guidelines for psychiatric inpatient after-care for deliberate self-poisoning and/or depression in young people are limited. Our explanatory model included suicidal level, depression, psychosis, older age, and available support persons, suggesting that the treating clinicians were making these discharge decisions for admission in keeping with those limited guidelines, although the balance of benefits and harms of psychiatric hospitalisation are not established. Future research examining patient experiences, effectiveness of psychiatric hospitalisation, and alternatives to hospitalisation is warranted.

SAT patterns and engineering and computer science college majors: an intersectional, state-level study

BackgroundNumerous efforts worldwide have been made to increase diversity in engineering and computer science (ECS), fields that pay well and promote upward mobility. However, in the United States (U.S.), females and students from underrepresented racial/ethnic minority groups (URM) still pursue ECS training far less than do their peers. The current study explored sex and racial/ethnic differences in ECS college enrollment as a function of math and verbal SAT score patterns (balanced or imbalanced) using an intersectional approach within a U.S. context. Data represented a census of students who took the SAT, graduated from all Virginia public high schools between 2006 and 2015, and enrolled in a 4-year college (N = 344,803).ResultsOur findings show, within each sex, URM students were at least as likely as their non-URM peers to enroll in ECS programs when they scored within similar SAT score ranges. Students were more likely to enroll in ECS programs if their SAT profile favored math, compared to students with similar math and verbal SAT scores (balanced profile). This overall pattern is notably less pronounced for URM female students; their propensity to major in ECS appeared to be largely independent of verbal scores.ConclusionsOur findings inform strategies to diversify ECS enrollment. If programs continue to emphasize SAT scores during admission decisions or if more systemic issues of resource allocation in secondary schools are not addressed, other efforts to broaden participation in ECS programs may fall short of goals. Our findings also highlight the importance of considering the intersection of sex and race/ethnicity for recruitment or other educational promotions.

Prosecuting rap: what does the case law tell us?

AbstractThis article explores the admissibility and use of rap music as evidence in English criminal trials. It presents findings from an analysis of over 30 appeal cases. As well as unpacking the link between rap, race and gangs that is prevalent in these cases, the article challenges the categorisation of rap as ‘bad character evidence’, and critiques the way in which questions of relevance and prejudicial effect have been addressed by the courts. In particular, when making admissibility decisions, the courts appear to give little consideration to the cultural context, artistic conventions or social influences within the rap music genre, or the racialised nature of rap evidence. It is argued that, if rap is to be admissible evidence, a much more rigorous and informed approach is required.

Admission practices following pediatric tonsillectomy: A survey of ASPO members.

Although evidence-based Clinical Practice Guidelines (CPGs) have specified postoperative admission criteria for pediatric tonsillectomy, there is substantial variation in guideline implementation and adherence among otolaryngologists in practice. We aimed to assess pediatric otolaryngologists' post-tonsillectomy admission practices and to examine patient and surgeon factors associated with differences in admission practices. An electronic cross-sectional survey was distributed to members of the American Society of Pediatric Otolaryngology (ASPO) to determine current practices regarding admission practices following pediatric tonsillectomy. Chi-square and Fisher's exact tests were performed to compare differences in adherence to tonsillectomy CPGs by respondent characteristics. The survey was sent to 644 pediatric otolaryngologists with a response rate of 19.1%. 37% of respondents reported "always" and 60% "often" using the Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) CPG to guide decision for admission. Years in practice was the factor most strongly associated with admission practices, with 10 or fewer years in practice significantly correlated with stricter adherence to the AAO-HNS CPG of overnight observation when Apnea-Hypopnea Index (AHI) ≥10, age <3 years, or O2 nadir <80%) (OR 4.2, p<0.001), as well as specific individual criteria such as an AHI ≥10 (OR 4.1, p=0.03). Respondents in an academic practice setting were more likely to admit children <3 years of age than those in private practice (OR 5.0, p=0.01). Admission practices varied among pediatric otolaryngologist survey respondents, and strict AAO-HNS CPG adherence was associated with fewer years in practice and academic practice setting. These results suggest that further study investigating factors influencing guideline adherence and post-tonsillectomy admission practices is warranted.

Barriers and Opportunities Regarding Implementation of a Machine Learning-Based Acute Heart Failure Risk Stratification Tool in the Emergency Department.

Hospital admissions for patients with acute heart failure (AHF) remain high. There is an opportunity to improve alignment between patient risk and admission decision. We recently developed a machine learning (ML)-based model that stratifies emergency department (ED) patients with AHF based on predicted risk of a 30-day severe adverse event. Prior to deploying the algorithm and paired clinical decision support, we sought to understand barriers and opportunities regarding successful implementation. We conducted semi-structured interviews with eight front-line ED providers and surveyed 67 ED providers. Audio-recorded interviews were transcribed and analyzed using thematic analysis, and we had a 65% response rate to the survey. Providers wanted decision support to be streamlined into workflows with minimal disruptions. Most providers wanted assistance primarily with ED disposition decisions, and secondarily with medical management and post-discharge follow-up care. Receiving feedback on patient outcomes after risk tool use was seen as an opportunity to increase acceptance, and few providers (<10%) had significant hesitations with using an ML-based tool after education on its use. Engagement with key front-line users on optimal design of the algorithm and decision support may contribute to broader uptake, acceptance, and adoption of recommendations for clinical decisions.

Impact of COVID-19 pandemic on emergency department length of stay and clinical outcomes of patients with severe pneumonia: A single-center observational study.

We examined the impact of COVID-19 pandemic on the emergency department length of stay (EDLOS) and clinical outcomes of patients with severe pneumonia admitted to the intensive care unit (ICU) through the emergency department (ED). This single-center retrospective observational study included adult patients with pneumonia admitted to the ICU through the ED between January and December 2019 (pre-pandemic) and between March 2020 and February 2021 (during-pandemic). We compared and analyzed the EDLOS by dividing it into pre-, mid-, and post-EDLOS and in-hospital mortality of patients with pneumonia admitted to the ICU according to the time of ED visits before and during the COVID-19 pandemic. Risk factors for in-hospital mortality according to the time of ED visits were analyzed using multiple logistic regression analysis. In total, 227 patients (73 patients pre-pandemic and 154 patients during the pandemic) with pneumonia admitted to the ICU through the ED were analyzed. During the COVID-19 pandemic, pre-, mid-, and post-EDLOS increased (P < .05), and the in-hospital mortality rate increased by 10.4%; however, this was not significant (P = .155). Multivariate logistic regression analysis revealed post-EDLOS (ED waiting time after making ICU admission decision) as an independent risk factor for in-hospital mortality of patients with pneumonia admitted to the ICU, pre-pandemic (odds ratio [OR] = 2.282, 95% confidence interval [CI]: 1.367–3.807, P = .002) and during the pandemic (OR = 1.126, 95% CI: 1.002–1.266, P = .047). Mid-EDLOS (ED time to assess, care, and ICU admission decision) was an independent risk factor for in-hospital mortality of patients with pneumonia admitted to the ICU during the COVID-19 pandemic (OR = 1.835, 95% CI: 1.089–3.092, P = .023). During the pandemic of emerging respiratory infectious diseases, to reduce in-hospital mortality of severe pneumonia patients, it is necessary to shorten the ED waiting time for admission by increasing the number of isolation ICU beds. It is also necessary to accelerate the assessment and care process in the ED, and make prompt decisions regarding admission to the ICU.

Regions of discrimination: felony records, race, and expressed college admissions policies

ABSTRACT Criminal records can have consequences for higher education attainment despite the benefits of college degrees for formerly incarcerated people. Using stratified random sampling of colleges and universities across the 50 states, this study examines how higher education institutions claim to use felony history in admission decisions, and the impact of race, geography, and institutional factors associated with these decisions. Findings indicate that admissions departments are more likely to tell an interested applicant with a stereotypical Black name and a non-violent felony record that their criminal histories will be considered in the application process compared to another prospective applicant with a stereotypical White name and non-violent felony record. Admissions departments in public institutions and institutions with higher racial diversity are less likely to consider felony history. Lastly, institutions in the former Confederate states are more likely to indicate using stringent reviews of applicants who disclose a felony compared to institutions in the former Union states. Institutions in the former border states and unincorporated states claim to be less likely to consider criminal history in the applicant review process compared to Union states. Recommendations for addressing these barriers to higher education are presented.

Admissions and Selection Criteria for Master’s Students in Music Education Degree Programs

The purpose of this study was to examine music education faculty members’ perceptions of admissions and selection criteria for entering master’s students in music education degree programs. Using multistage sampling, we distributed a questionnaire to music education faculty at National Association of Schools of Music (NASM)-accredited institutions in the United States that offered master’s degrees in music education. Results indicated that music education faculty were involved in most admission decisions, and that transcripts, interviews, and letters of recommendation were the most common materials submitted for review. In response to open-ended questions, participants reported that their admission decisions are usually determined by four criteria: academic skills, demonstration of potential as a graduate student, demonstration of teaching ability, and less measurable indicators. This exploration of the admissions and selection criteria that music education faculty use when making admission decisions provides music teacher educators a greater understanding of this important transition point.

Critically Ill COVID-19 Patients Show Reduced Point of Care-Measured Butyrylcholinesterase Activity-A Prospective, Monocentric Observational Study.

A biomarker for risk stratification and disease severity assessment in SARS-CoV-2 infections has not yet been established. Point of care testing (POCT) of butyrylcholinesterase (BChE) enables early detection of systemic inflammatory responses and correlates with disease severity in sepsis and burns. In acute care or resource-limited settings, POCT facilitates rapid clinical decision making, a particularly beneficial aspect in the management of pandemic situations. In this prospective observational study, POCT-measured BChE activity was assessed in 52 critically ill COVID-19 patients within 24 h of ICU admission and on the third and seventh day after ICU admission. Forty (77%) of these patients required venovenous extracorporeal membrane oxygenation (vvECMO). In critically ill COVID-19 patients, BChE activity is significantly decreased compared with healthy subjects, but also compared with other inflammatory conditions such as sepsis, burns, or trauma. POCT BChE activity reflects the severity of organ dysfunction and allows prediction of 28-day mortality in critically ill COVID-19 patients. Implementing early POCT BChE measurement could facilitate risk stratification and support admission and transfer decisions in resource-limited settings.

Building sustainable approaches to recruit, retain, and professionalize Black, Latinx, and American Indian students interested in dental careers.

Only twelve percent of dentists in 2020 self-identified as being Black, Latinx, or "Other," which includes American Indian. Moreover, the proportion of dentists from these groups profoundly fails to reflect the demographic composition of the U.S. overall. Evidence-based, ethically-grounded approaches are needed to successfully and continuously recruit and retain Black, Latinx, and American Indian dental students. We explored the barriers and opportunities to sustainable pathways to the dental profession. We conducted focus groups in 2021 with current Black, Latinx, and American Indian dental students and key informant interviews with dental school administrators using elicitation guides developed for this project. We completed a thematic analysis of data to identify and check findings to strengthen validity. We identified the following successes, challenges, and opportunities for recruiting Black, Latinx, and American Indian dental students. Successes include institutional investment to build and sustain pathways, yet many of these practices are institution- or administrator-specific and may defy replication. Challenges are more widespread, and include weak accreditation standards; systemic bias and failure to consider candidates holistically in admissions decisions; costs associated with admissions test preparation and volunteer shadowing; transportation, geography, school culture and language/citizenship status. Opportunities include mentoring, scholarships, removing bias from admissions, institutional financial investment in pathway programs, and peer norming among programs. Building sustainable pathways involve early support of students, removing systemic biases, and institutional commitments to equity to create a workforce to meet population needs.

Nursing home directors of nursing experiences regarding safety among residents with obesity

The prevalence of nursing home (NH) residents with obesity is rising. Perspectives of NH Directors of Nursing (DONs) who oversee care trajectories for residents with obesity is lacking. This study aimed to describe the experiences of NH DONs regarding care and safety for NH residents with obesity. An adapted version of Donabedian's structure-process-outcome model guided this qualitative descriptive study. Semi-structured interviews were conducted with 15 DONs. Data were analyzed using directed content analysis, and findings are presented under the model's constructs. We learned that admission decisions for NH referrals of patients with obesity are complex due to reimbursement issues, available space and resources, and resident characteristics. DONs described the need to coach and mentor Certified Nursing Assistants to provide safe quality care and that more staff education is needed. We identified novel findings regarding the challenges of short-term residents’ experience transitioning out of care due to limited resources.

Comparison of student and faculty interviewers using ratings data for admissions decisions.

The aim of this study was to evaluate the correlations of cognitive and noncognitive dental school admission factors with interview ratings provided by faculty and student interviewers. Interviewees for the 2019-2021 admissions cycles underwent a 90-minute period consisting of two 45-min interviews and received two interview scores ranging from 1.0 to 2.3. Regression models were utilised to evaluate factors associated with interviewer type and admission status, The correlation strength between faculty and student interview scores was assessed. A total of 177 applicants were interviewed, and 69 students were admitted over two admission cycles. Admitted students received higher interview ratings compared with nonadmitted applicants after adjusting for cognitive and noncognitive admission factors (average difference=-0.068; 95% CI=-0.123, -0.014). No statistically significant relationship was found between any cognitive admissions factor and interview score. However, having prior leadership role experiences was associated with better faculty score, after adjusting for student interviewee score. There was a strong linear correlation (r=.92) between faculty and student interview scores, with 0.809 change in faculty score with each additional student interview score (95% CI=0.735, 0.883). The relationship between faculty and student scores was linear and strongly correlated, suggesting that faculty and student interviewers were comparable in their interview scoring. Leadership experience and potential could be advantageous qualities that improve faculty interviewer ratings. However, having a mix of faculty and Student interviewers may promote evaluation of candidates from different aspects, as students are familiar with the learning environment in dental school and may provide a unique perspective on an applicant's background and suitability for the program.

Hospitalization following an emergency-department visit for worsening heart failure: The role of left ventricular ejection fraction

Introduction and objectivesPatients with worsening heart failure (WHF) are frequently hospitalized. However, some of the patients with WHF are discharged from the emergency department without hospitalization. The factors influencing the decision of admission are heterogeneous and, in most cases, remain not well-defined. This study aimed to analyze whether left ventricular ejection fraction (LVEF) influences admission decisions following a visit to the emergency department for WHF. Patients and methodsThis is a retrospective analysis of 3168 patients discharged from a hospitalization for acute heart failure in a single-center in Spain. During follow-up, visits to the emergency department for WHF, including those hospitalized (WHF-readmissions) and episodes of WHF directly discharged without hospitalization in 24h (WHF-DDWH), were recorded. The association between the LVEF categories (<50% and ≥50%) and recurrent WHF-DDWH was evaluated by negative binomial regression. Estimates of risk were expressed as incidence rate ratios (IRR). ResultsThe mean age (SD) of the study sample was 73.5 (11.2) years, and 1658 (52.3%) showed LVEF>50%. At a median (percentile 25% to percentile 75%) follow-up of 2.7 (1.0–5.8) years, 3341 episodes of WHF in 1439 patients were recorded. Of them, we registered 743 episodes of WHF-DDWH in 468 patients (22.2%). Compared to patients with LVEF<50%, those with LVEF≥50% exhibited an adjusted increased risk of recurrent WHF-DDWH (IRR: 1.36, CI 95%: 1.13–1.62, p=0.001). ConclusionsFollowing an acute heart failure admission, patients with LVEF≥50% showed an increased risk of same-day discharge for WHF.

U.S. Emergency Department Telepsychiatry Use in 2019.

Introduction: Although many emergency departments (EDs) receive telehealth services for psychiatry, or telepsychiatry, to manage acute psychiatric emergencies, national research on the usage of ED telepsychiatry is limited. To investigate ED telepsychiatry usage in the pre-COVID-19 era, we surveyed a sample of EDs receiving telepsychiatry in 2019, as a follow-up to a survey targeted to similar EDs in 2017. Methods: All U.S. EDs open in 2019 (n = 5,563) were surveyed to characterize emergency care. A more in-depth second survey on telepsychiatry use (2019 ED Telepsychiatry Survey) was then sent to 235 EDs. Of these EDs, 130 were randomly selected from those that reported telepsychiatry receipt in 2019, and 105 were selected based on their participation in a similar survey in 2017 (2017 ED Telepsychiatry Survey). Results: Of the 235 EDs receiving the 2019 Telepsychiatry Survey, 192 (82%) responded and 172 (90% of responding EDs) confirmed 2019 telepsychiatry receipt. Of these, five were excluded for missing data (analytic samplen = 167). Telepsychiatry was the only form of emergency psychiatric services for 92 (55%) EDs. The most common usage of telepsychiatry was for admission or discharge decisions (82%) and transfer coordination (70%). The most commonly reported telepsychiatry mental health consultants were psychiatrists or other physician-level mental health professionals (74%). Discussion: With telepsychiatry as the only form of psychiatric services for most telepsychiatry-receiving EDs, this innovation fills a critical gap in access to emergency psychiatric care. Further research is needed to investigate the impact of the COVID-19 pandemic on usage of ED telepsychiatry.

C-Reactive Protein Velocity (CRPv) as a New Biomarker for the Early Detection of Acute Infection/Inflammation.

C-reactive protein (CRP) is considered a biomarker of infection/inflammation. It is a commonly used tool for early detection of infection in the emergency room or as a point-of-care test and especially for differentiating between bacterial and viral infections, affecting decisions of admission and initiation of antibiotic treatments. As C-reactive protein is part of a dynamic and continuous inflammatory process, a single CRP measurement, especially at low concentrations, may erroneously lead to a wrong classification of an infection as viral over bacterial and delay appropriate antibiotic treatment. In the present review, we introduce the concept of C-reactive protein dynamics, measuring the velocity of C-reactive protein elevation, as a tool to increase this biomarker’s diagnostic ability. We review the studies that helped define new metrics such as estimated C-reactive protein velocity (velocity of C-reactive protein elevation from symptoms’ onset to first C-reactive protein measurement) and the measured C-reactive protein velocity (velocity between sequential C-reactive protein measurements) and the use of these metrics in different clinical scenarios. We also discuss future research directions for this novel metric.
