Major trauma with only dynamic criteria: is the routine use of whole-body CT as a first level examination justified?

PURPOSE: Risks and benefits of systematic use of whole-body CT (WBCT) in patients with major trauma when no injury is clinically suspected is still subject of controversy. WBCT allows early identification of potentially evolving lesions, but exposes patients to the risk of high radiation dose and iodine contrast agent. The study aimed to assess if WBCT could be avoided in trauma patients with negative clinical examination. MATERIALS AND METHODS: This retrospective study included polytrauma patients admitted to the Emergency Department in a six-month period, who had undergone a WBCT scan for major dynamic criteria, with hemodynamic stability, absence of clinical and medical risk factors for major trauma. The patients (n = 233) were divided into two groups according to the absence (n = 152) or presence (n = 81) of clinical suspicion of organ injury. The WBCT results were classified as negative, positive for minor and positive for major lesions. RESULTS: The average patient age was 44 years. CT scans were completely negative in 111 (47.6%) patients, whose 104 (93.7%) were in the negative clinic group. 122 (52.4%) CT scans were positive, 69 (56.6%) for minor lesions and 53 (43.4%) for major lesions. Among the 48 (39.3%) positive CT scans in patients with negative clinic, only 5 (10.4%) were positive for major lesions. We found a significant difference in the frequency of injuries between the clinically negative and clinically positive patient groups (p < 0.001). CONCLUSION: A thorough clinical examination associated with a primary radiological evaluation may represent a valid diagnostic approach for trauma with only major dynamic criteria to limit the use of WBCT.

A Comparison of Two Widely Used Risk Stratification Systems for Thyroid Nodule Sonographic Evaluation.

BACKGROUND: The 2015 American Thyroid Association (ATA2015) and the American College of Radiology Thyroid Imaging and Reporting Data System (ACR TI-RADS) are two widely used thyroid sonographic systems. OBJECTIVES: To compare the two systems for accuracy of cancer risk prediction. METHODS: Preoperative ultrasound images from 265 patients who underwent thyroidectomy at our hospital from January 2012 to March 2019 were retrospectively categorized by the ACR TI-RADS and ATA2015 systems. Diagnostic performances were compared. RESULTS: Of 238 nodules assessed, 115 were malignant. Malignancy risks for the five ACR TI-RADS categories were 0%, 7.5%, 11.4%, 59.6%, and 90.0%. Malignancy risks for the five ATA2015 categories were 0%, 6.8%, 17.0%, 55.5%, and 92.1%. The proportion of total nodules biopsied was higher with the ATA2015 system than the ACR TI-RADS system: 88.7% vs. 66.3%. Proportions of malignant nodules and benign nodules biopsied were higher with ATA2015 than with ACR TI-RADS: 93.3% vs. 87.8% and 84.4% vs. 46.3%, respectively. Specificity and sensitivity rates were 53.6% and 84.3%, respectively, for ACR TI-RADS, and 15.5% and 93.3%, respectively, for ATA2015. The two systems showed similarly accurate diagnostic performance (AUC > 0.88). False negative rates for ACR TI-RADS and ATA2015 were 15.6% and 6.6%, respectively. Rates of missed aggressive cancer were similar for the two systems: 3.4% and 3.7%, respectively. CONCLUSIONS: ACR TI-RADS was superior to ATA2015 in specificity and avoiding unnecessary biopsies. ATA2015 yielded better sensitivity and a lower false negative rate. Identification of aggressive cancers was identical in the two systems.

Association Between a Common, Benign Genotype and Unnecessary Bone Marrow Biopsies Among African American Patients.

Importance: Up to two-thirds of African American individuals carry the benign rs2814778-CC genotype that lowers total white blood cell (WBC) count. Objective: To examine whether the rs2814778-CC genotype is associated with an increased likelihood of receiving a bone marrow biopsy (BMB) for an isolated low WBC count. Design, Setting, and Participants: This retrospective genetic association study assessed African American patients younger than 90 years who underwent a BMB at Vanderbilt University Medical Center, Mount Sinai Health System, or Children's Hospital of Philadelphia from January 1, 1998, to December 31, 2020. Exposure: The rs2814778-CC genotype. Main Outcomes and Measures: The proportion of individuals with the CC genotype who underwent BMB for an isolated low WBC count and had a normal biopsy result compared with the proportion of individuals with the CC genotype who underwent BMB for other indications and had a normal biopsy result. Results: Among 399 individuals who underwent a BMB (mean [SD] age, 41.8 [22.5] years, 234 [59%] female), 277 (69%) had the CC genotype. A total of 35 patients (9%) had clinical histories of isolated low WBC counts, and 364 (91%) had other histories. Of those with a clinical history of isolated low WBC count, 34 of 35 (97%) had the CC genotype vs 243 of 364 (67%) of those without a low WBC count history. Among those with the CC genotype, 33 of 34 (97%) had normal results for biopsies performed for isolated low WBC counts compared with 134 of 243 individuals (55%) with biopsies performed for other histories (P < .001). Conclusions and Relevance: In this genetic association study, among patients of African American race who had a BMB with a clinical history of isolated low WBC counts, the rs2814778-CC genotype was highly prevalent, and 97% of these BMBs identified no hematologic abnormality. Accounting for the rs2814778-CC genotype in clinical decision-making could avoid unnecessary BMB procedures.

Occult Malignancy in Adult Tonsillectomy for Benign Indication.

OBJECTIVE: National pathology guidelines recommend full pathologic analysis for all adult tonsillectomy specimens. We evaluated the available data on occult malignancy in adult tonsillectomy for benign indication, and created a screening system to reduce the risk of missed malignancies if routine histopathologic examination were to be discontinued. STUDY DESIGN: Retrospective chart review and systematic review of the literature. SETTING: Tertiary care academic hospital and multi-hospital private healthcare system. SUBJECTS AND METHODS: A systematic literature review identified case series of adult tonsillectomy. Retrospective chart review at our institutions from 2000 to 2016 produced an additional case series. The pooled rate of occult malignancy was determined, and re-analyzed using criteria based on preoperative risk factors designed to identify patients requiring full pathologic analysis. The predicted effects of prospective application of the proposed criteria were calculated. Pooled occult malignancy prevalence was estimated. RESULTS: Literature review and our own case series yielded 12,094 total cases. Occult malignancy prevalence in the combined data was 0.033%, representing four occult malignancies. Three out of the four would have been selected for full pathology preoperatively with use of the proposed criteria. Statistical analysis indicates that the predicted frequency of occult malignancy incidence in cases negative for the criteria is 0.01%, or 1/10,000. CONCLUSION: Application of the proposed criteria to adults undergoing tonsillectomy for benign indication identifies a subset of patients with an estimated incidence of occult malignancy similar to that reported for pediatric tonsillectomy, and potentially may permit safe elimination of pathologic analysis of their tonsil specimens. LEVEL OF EVIDENCE: Pooled analysis of case series from the literature and a single institution, level 4.

Preoperative intravenous rehydration for patients with pheochromocytomas and paragangliomas: is it necessary? A propensity score matching analysis.

BACKGROUND: Preoperative intravenous rehydration for patients with pheochromocytomas and paragangliomas (PPGLs) is widely used in many medical centers, but its usefulness has not been well evaluated. The objective of this study was to compare the perioperative hemodynamics and early outcome between patients who received preoperative intravenous rehydration and those without for resection of PPGLs. METHODS: In this retrospective propensity score-matched cohort study, the data of patients who underwent surgery for PPGLs were collected. Patients were divided into two groups depending on whether they received or did not receive intravenous rehydration preoperatively. The primary endpoint was intraoperative hypotension, described as the cumulative time of mean arterial pressure < 65 mmHg averaged by surgery duration. RESULTS: Among 231 enrolled patients, 113 patients received intravenous rehydration of ≥2000 ml daily for ≥2 days before surgery and 118 patients who did not have any intravenous rehydration before surgery. After propensity score matching, 85 patients remained in each group. The median cumulative time of mean arterial pressure < 65 mmHg averaged by surgery duration was not significantly different between rehydrated patients and non-rehydrated patients (median 3.0% [interquartile range 0.2-12.2] versus 3.8% [0.0-14.2], median difference 0.0, 95%CI - 1.2 to 0.8, p = 0.909). The total dose of catecholamines given intraoperatively, volume of intraoperative fluids, intraoperative tachycardia and hypertension, percentage of patients who suffered from postoperative hypotension, postoperative diuretics use, and postoperative early outcome between the two groups were not significantly different either. CONCLUSIONS: For patients with PPGLs, preoperative intravenous rehydration failed to optimize perioperative hemodynamics or improve early outcome.

Validation of Appropriate Use Criteria for Coronary Computed Tomographic Angiography for Chest Pain Evaluation in a Tertiary Care Emergency Room.

PURPOSE: Appropriate use criteria (AUC) defines the appropriateness of imaging procedures for specific clinical scenarios to promote evidence-based utilization and improve cost-effective care. The goal of this study was to assess the diagnostic yield and downstream health care resource utilization according to the AUC categorization for coronary computed tomography angiography (CCTA) in emergency department (ED) patients presenting with chest pain. MATERIALS AND METHODS: A total of 789 consecutive patients in the ED with chest pain and no known coronary artery disease (CAD) who underwent CCTA were classified as appropriate, uncertain, or inappropriate use according to the 2010 AUC. We abstracted index and 30-day data from the electronic medical record to determine diagnostic yield (rate of obstructive CAD and revascularization) and health care resource utilization (downstream stress test and 30-d hospital return rate). RESULTS: Rates of appropriate, uncertain, and inappropriate utilization were 48.4%, 48.8%, and 2.8%. Among appropriate, uncertain, and inappropriate classifications, rates of obstructive CAD were 9%, 8%, and 32% (P=0.002); rates of revascularization were 3%, 1%, and 36% (P<0.001); downstream stress test utilization rates were 5% versus 5% versus 14% (P=0.17), and 30-day hospital return rates were 6% versus 6% versus 5% (P>0.99), respectively. CONCLUSIONS: Appropriate and uncertain uses were associated with low diagnostic yield compared with inappropriate use; however, our findings do not demonstrate differences between appropriate use categories with respect to downstream health care resource utilization. Further studies are needed to define the role of AUC for CCTA in the ED setting.

What influences clinicians to choose wisely?

AIM: To evaluate the effectiveness of awareness-raising by the Choosing Wisely campaign in a New Zealand public hospital to reduce routine pre-operative testing and to determine what can be done to bring about change in clinician behaviour. METHODS: Short, semi-structured, one on-one interviews were conducted with 15 doctors of varying seniority from general surgery who were exposed to the campaign between August and October 2018. The interviews covered four general topics including background information, asking about awareness and effectiveness of Choosing Wisely campaign, exploring barriers to changing clinician behaviour around pre-operative testing and exploring potential interventions which may be useful to change behaviour. Data were analysed using Braun and Clarke thematic analysis methodology. RESULTS: Four themes and 17 sub-themes emerged from the interviews. The main themes included awareness of Choosing Wisely, thoughts around pre-operative testing, barriers for changing clinician behaviour and strategies for reducing unnecessary pre-operative testing. CONCLUSION: The findings of this study suggest that a strategy that relies on revising guidelines and raising staff awareness alone is likely to be of limited effectiveness in reducing unnecessary pre-operative testing. In addition to increasing clinician awareness of evidence-based recommendations on unnecessary testing, other strategies may be needed to support behaviour change.

Predicting Biopsy Outcomes During Active Surveillance for Prostate Cancer: External Validation of the Canary Prostate Active Surveillance Study Risk Calculators in Five Large Active Surveillance Cohorts.

BACKGROUND: Men with prostate cancer (PCa) on active surveillance (AS) are followed through regular prostate biopsies, a burdensome and often unnecessary intervention, not without risks. Identifying men with at a low risk of disease reclassification may help reduce the number of biopsies. OBJECTIVE: To assess the external validity of two Canary Prostate Active Surveillance Study Risk Calculators (PASS-RCs), which estimate the probability of reclassification (Gleason grade ≥7 with or without >34% of biopsy cores positive for PCa) on a surveillance biopsy, using a mix of months since last biopsy, age, body mass index, prostate-specific antigen, prostate volume, number of prior negative biopsies, and percentage (or ratio) of positive cores on last biopsy. DESIGN, SETTING, AND PARTICIPANTS: We used data up to November 2017 from the Movember Foundation's Global Action Plan (GAP3) consortium, a global collaboration between AS studies. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: External validity of the PASS-RCs for estimating reclassification on biopsy was assessed by calibration, discrimination, and decision curve analyses. RESULTS AND LIMITATIONS: Five validation cohorts (Prostate Cancer Research International: Active Surveillance, Johns Hopkins, Toronto, Memorial Sloan Kettering Cancer Center, and University of California San Francisco), comprising 5105 men on AS, were eligible for analysis. The individual cohorts comprised 429-2416 men, with a median follow-up between 36 and 84 mo, in both community and academic practices mainly from western countries. Abilities of the PASS-RCs to discriminate between men with and without reclassification on biopsy were reasonably good (area under the receiver operating characteristic curve values 0.68 and 0.65). The PASS-RCs were moderately well calibrated, and had a greater net benefit than most default strategies between a predicted 10% and 30% risk of reclassification. CONCLUSIONS: Both PASS-RCs improved the balance between detecting reclassification and performing surveillance biopsies by reducing unnecessary biopsies. Recalibration to the local setting will increase their clinical usefulness and is therefore required before implementation. PATIENT SUMMARY: Unnecessary prostate biopsies while on active surveillance (AS) should be avoided as much as possible. The ability of two calculators to selectively identify men at risk of progression was tested in a large cohort of men with low-risk prostate cancer on AS. The calculators were able to prevent unnecessary biopsies in some men. Usefulness of the calculators can be increased by adjusting them to the characteristics of the population of the clinic in which the calculators will be used.

Routine postoperative radiographs after tibia plateau fixation have minimal impact on patient care.

INTRODUCTION: Common practice in orthopedic surgery is to obtain postoperative radiographs to evaluate for healing or complications. Images obtained in the post-anesthesia care unit (PACU) have not been shown to positively impact patient care. This study plans to evaluate the clinical utility and cost-effectiveness of PACU postoperative radiographs following tibial plateau open reduction and internal fixation (ORIF). METHODS: Data from 211 patients who underwent a tibial plateau ORIF over a 5-year period at a single institution were retrospectively reviewed to determine if a patient received a postoperative radiograph in the PACU. Radiograph and clinical notes were reviewed to determine if postoperative radiograph resulted in management changes. Radiograph charges were calculated using CPT codes. RESULTS: A total of 142 of 211 patients (67.3%) who underwent tibial plateau ORIF received a postoperative radiograph while in the PACU. The majority of the radiographs had normal findings (88.7%). Of the 142 patients with postoperative imaging, subsequent management changes occurred for only one patient (0.7%). In this case, an incidental foot fracture was found which resulted in further CT imaging to assess the fracture. Other abnormal radiograph readings (11.3%) were generally due to incidental, chronic findings that did not require management changes. The average postoperative radiograph cost was $433.55 per patient, totaling $91,480 for 142 patients over a 5-year period. CONCLUSIONS: Routine postoperative radiographs following tibial plateau ORIF resulted in minimal management change patients in this series. The substantial cost of postoperative radiographs yielding little clinical utility suggests the use of routine PACU imaging following tibial plateau ORIF should be discontinued. Imaging would only be indicated in situations where intraoperative complications are suspected, thus reducing unnecessary imaging and patient cost.

Fungal Diagnostic Stewardship in Bronchoscopy Specimens for Immunocompetent Patients in the Intensive Care Unit.

OBJECTIVE: To evaluate the diagnostic yield of fungal smears and cultures from bronchial lavage and wash specimens obtained from immunocompetent patients in the intensive care unit (ICU) because respiratory tract samples from patients in the ICU often undergo extensive microbiological testing. PATIENTS AND METHODS: In total, we enrolled 112 immunocompetent adult patients treated in the medical and surgical ICU between July 1, 2016, and June 30, 2017. We evaluated whether the results of fungal smears and cultures of specimens obtained from bronchoscopy and bronchoalveolar lavage changed patient care. RESULTS: In total, 131 bronchoscopic specimens and 31 bronchoalveolar lavage specimens were tested for fungi. Cultures were held for an estimated 4680 culture-days. Two results changed patient therapy. In both cases, other routine tests provided the same information as fungal culture before these results were returned. CONCLUSION: In immunocompetent, critically ill patients, fungal culture of respiratory tract specimens does not add diagnostic value. Routine fungal culture of respiratory tract specimens should be discouraged in this population.

Misdiagnosis of ARVC leading to inappropriate ICD implant and subsequent ICD removal - lessons learned.

INTRODUCTION: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited progressive cardiomyopathy characterized by frequent life-threatening arrhythmias. The diagnosis of ARVC is challenging and is on the basis of a set of major and minor criteria as described by the modified Task Force Criteria (TFC). We report our clinical experience in a series of patients who were misdiagnosed with ARVC and subsequently underwent removal of their implantable cardioverter defibrillator (ICD) after a re-evaluation at our center. METHODS AND RESULTS: We studied 12 patients who were misdiagnosed with ARVC and had ICD implantation before our assessment. All patients had a repeat evaluation and were scored according to TFC before ICD removal. Cardiac magnetic resonance imaging (CMR) studies performed at outside institutions during the initial evaluation were reported abnormal and classified as meeting major TFC in ninety percent of patients. The most common abnormality reported was fatty infiltration of the right ventricular (RV) free wall and/or presence of focal intra-myocardial fat in six patients (50%). On re-evaluation, none of these findings fulfilled the TFC for the diagnosis. CONCLUSION: This study demonstrated that high dependence on misinterpretation of CMR along with a misunderstanding of the TFC evaluation are the main reasons for the misdiagnosis of ARVC. Despite the updated criteria for almost a decade, this study reminds that the diagnosis of ARVC is complex and hence careful TFC evaluation and consideration of multiple cardiac test results should be the focused approach for clinicians when confronted with suspected ARVC patients.

Preventing Unnecessary Intubations: A 5-Year Regional Burn Center Experience Using Flexible Fiberoptic Laryngoscopy for Airway Evaluation in Patients With Suspected Inhalation or Airway Injury.

The decision to intubate acute burn patients is often based on the presence of classic clinical exam findings. However, these findings may have poor correlation with airway injury and result in unnecessary intubation. We investigated flexible fiberoptic laryngoscopy (FFL) as a means to diagnose upper airway thermal and inhalation injury and guide airway management. A retrospective chart review of all burn patients who underwent FFL from 2013 to 2017 was performed. Their charts were reviewed to determine the indications for FFL including the historical data and physical exam findings that indicated airway injury as well as patient age, TBSA, type and depth of burn injury, carboxyhemoglobin level, and clinical course. Fifty-one patients underwent FFL, with an average TBSA of 6.5% (range 0.5-38.0%) and carboxyhemoglobin level of 3.5%. Burn mechanism was flame (35.3%) or flash (51.0%), with 50% occurring in enclosed spaces. In all cases, the decision to perform FFL was based on physical exam findings meeting criteria for intubation, including facial burns, singed nasal hairs, nasal soot, voice change, throat pain or abnormal sensation, shortness of breath, carbonaceous sputum, wheezing, or stridor. Based on FFL, 9 patients (17.7%) were treated with steroids, 28 patients (54.9%) received supportive care, and 6 patients (11.8%) had repeat FFL for monitoring. One patient was intubated after repeat FFL examination. All patients who underwent FFL met traditional criteria for intubation based on exam, however 98% were monitored without issues based on FFL findings. FFL is a valuable tool that can lead to fewer intubations in acute burn patients with a stable respiratory status for whom history and physical exam suggest upper airway injury.

Neck of femur fracture: Previous history of malignancy is not an indication to send femoral head for routine histology.

BACKGROUND: Neck of femur fractures is the most common fractures associated with low-velocity injury in the elderly. Some patients may require further histological examination of the femoral head due clinical suspicion of malignance as a cause of fracture. OBJECTIVES: To review whether standard screening question(s) could be used to identify patients that require histological examinations following neck of femur fracture. STUDY DESIGN AND METHODS: Femoral heads sent for histological examination over a period of 5 years were identified from hospital database. All patients presenting acutely with neck of femur fracture above the age of 70 were included, and their case notes were retrospectively reviewed. Reason for histopathological examination were categorised into three screening questions: (Q1) clinical suspicion based on history alone, i.e. neck of femur fracture with no clear history of fall or trauma or preceding hip pain, (Q2) radiological evidence of suspicious abnormality on admission radiographs, (Q3) previous history of malignancy or concurrent malignancy or (Q4) combination of above. RESULTS: In total, 119 samples of femoral head were sent and 18 patients had a positive histology. The sensitivity and specificity of these questions individually showed very poor correlation to positive histology with lowest for (Q3) previous history of malignancy (0.39 and 0.51, respectively). However, combining Q1 and Q2 the sensitivity is improved to 1.0 (95% CI 1.0-1.0) and specificity to 0.35 (95% CI 0.25-0.44) with a positive predictive value of 0.21 (95% CI 0.13-0.30) and negative predictive value of 1.00 (95% CI 1.00-1.00). CONCLUSION: History of previous malignancy poorly correlates with positive histology. Routine request based on these screening criteria is not cost-effective in patient management. LEVEL OF EVIDENCE: Prognostic level III.

Management and treatment of cervical intraepithelial neoplasia in the Netherlands after referral for colposcopy.

INTRODUCTION: The aim of this study was to describe trends in the diagnosis and treatment of women referred from the national screening program with cervical intraepithelial neoplasia (CIN) in the Netherlands, and to compare these trends with national guidelines and identify potential areas for improvement for the new primary high-risk HPV screening program. MATERIAL AND METHODS: We conducted a population-based cohort study using data from the Dutch pathology archive. Women aged 29-63 years who took part in the Dutch cervical screening program between 1 January 2005 and 31 December 2014 were selected. Three referral groups were identified: direct referrals and those referred after either one (first indirect referrals) or two (second indirect referrals) repeat cytology tests, totaling 85 239 referrals for colposcopy. The most invasive management technique and the most severe diagnosis of each screening episode was identified. Rates of management techniques were calculated separately by referral type, highest CIN diagnosis and age group. RESULTS: In all, 85.1% of CIN 3 lesions were treated with excision (either large excision or hysterectomy) and 26.4% of CIN 1 lesions were treated with large excision. Rates of overtreatment (CIN 1 or less) in see-and-treat management were higher for indirect referrals than for direct referrals and increased with age. Large excision rates increased with CIN diagnosis severity. CONCLUSIONS: Despite guideline recommendations not to treat, CIN 1 lesions were treated in just over 25% of cases and approximately 15% of CIN 3 lesions were possibly undertreated. Given the expected increase in CIN detection in the new primary high-risk HPV screening program, reduction in CIN 1 treatment and CIN 2 treatment in younger women is needed to avoid an increase in potential harm.

Should UK based Physiotherapists Choose Wisely?

In 2012 the Choose Wisely campaign was launched in the United States in order to address concerns regarding medicalisation, over diagnosis and medical consumerism. The campaign has now spread internationally and includes a number of countries including Canada, Australia, New Zealand and Germany. The primary aim of the campaign is to facilitate healthcare professionals and patients to question the overall utility of medical interventions. Professionals through their professional organisations identify at least five commonly used interventions or tests, within their areas of speciality, which they feel provided no or little benefit to patients. This paper provides the background to the Choose Wisely campaign. The paper reviews the concepts of medicalisation, over diagnosis and medical consumerism, before considering the utility of the campaign in the UK alongside other forms of governance such as NICE. The paper goes on to consider distributive justice as the principal ethical issue related to the campaign. The paper concludes by asking if UK based Physiotherapists should Choose Wisely.

The HEART score is useful to predict cardiovascular risks and reduces unnecessary cardiac imaging in low-risk patients with acute chest pain.

The present study was to investigate whether the HEART score can be used to evaluate cardiovascular risks and reduce unnecessary cardiac imaging in China.Acute coronary syndrome patients with the thrombosis in myocardial infarction risk score < 2 were enrolled in the emergency department. Baseline data were collected and a HEART score was determined in each participant during the indexed emergency visit. Participants were follow-up for 30 days after discharge and the studied endpoints included acute myocardial infarction, cardiovascular mortality and all-cause mortality.A total of 244 patients were enrolled and 2 was loss of follow-up. The mean age was 50.4 years old and male patients accounted for 64.5%. Substernal pain and featured as pressure of the pain accounted for 34.3% and 39.3%, respectively. After 30 days' follow-up, no patient in the low-risk HEART score group and 2 patients (1.5%) in the high risk HEART score group had cardiovascular events. The sensitivity of HEART score to predict cardiovascular events was 100% and the specificity was 46.7%. The potential unnecessary cardiac testing was 46.3%. Cox proportional hazards regression analysis showed that per one category increase of the HEART score was associated with nearly 1.3-fold risk of cardiovascular events.In the low-risk acute chest pain patients, the HEART score is useful to physicians in evaluating the risk of cardiovascular events within the first 30 days. In addition, the HEART score is also useful in reducing the unnecessary cardiac imaging.

Should we be testing for urogenital Mycoplasma hominis, Ureaplasma parvum and Ureaplasma urealyticum in men and women? - a position statement from the European STI Guidelines Editorial Board.

At present, we have no evidence that we are doing more good than harm detecting and subsequently treating Mycoplasma hominis, Ureaplasma parvum and Ureaplasma urealyticum colonizations/infections. Consequently, routine testing and treatment of asymptomatic or symptomatic men and women for M. hominis, U. urealyticum and U. parvum are not recommended. Asymptomatic carriage of these bacteria is common, and the majority of individuals do not develop any disease. Although U. urealyticum has been associated with urethritis in men, it is probably not causal unless a high load is present (likely carriage in 40-80% of detected cases). The extensive testing, detection and subsequent antimicrobial treatment of these bacteria performed in some settings may result in the selection of antimicrobial resistance, in these bacteria, 'true' STI agents, as well as in the general microbiota, and substantial economic cost for society and individuals, particularly women. The commercialization of many particularly multiplex PCR assays detecting traditional non-viral STIs together with M. hominis, U. parvum and/or U. urealyticum has worsened this situation. Thus, routine screening of asymptomatic men and women or routine testing of symptomatic individuals for M. hominis, U. urealyticum and U. parvum is not recommended. If testing of men with symptomatic urethritis is undertaken, traditional STI urethritis agents such as Neisseria gonorrhoeae, Chlamydia trachomatis, M. genitalium and, in settings where relevant, Trichomonas vaginalis should be excluded prior to U. urealyticum testing and quantitative species-specific molecular diagnostic tests should be used. Only men with high U. urealyticum load should be considered for treatment; however, appropriate evidence for effective treatment regimens is lacking. In symptomatic women, bacterial vaginosis (BV) should always be tested for and treated if detected.
