Patient-specific affect-abdominal pain interactions in endometriosis: an experience sampling method (ESM) study.

OBJECTIVES: Cross-sectional studies show that endometriosis-related pain is associated with affect. Measuring these symptoms in real-time in a longitudinal perspective yields the ability to analyze the temporal relationship between variables. The aim was to evaluate the association between affect and abdominal pain, using the Experience Sampling Method (ESM) as a real-time, randomly repeated assessment. METHODS: Thirty-four endometriosis patients and 31 healthy subjects completed up to 10 real-time self-assessments concerning abdominal pain and affective symptoms during seven consecutive days. RESULTS: Endometriosis patients experienced more abdominal pain and negative affective symptoms, and scored lower on positive affect compared to healthy controls. A significant association was found between abdominal pain and both positive and negative affect in endometriosis patients. For healthy controls, less strong or non-significant associations were found. When looking at abdominal pain as a predictor for affect and vice versa, we found that only in endometriosis patients, pain was subsequently accompanied by negative affect, and positive affect may alleviate pain in these patients. CONCLUSIONS: This study confirms a concurrent and temporal relationship between affect and abdominal pain in endometriosis patients and supports the use of real-time symptom assessment to interpret potential influencers of abdominal complaints in patients with endometriosis.

URGENT 1.5: diagnostic accuracy of the modified HEART score, with fingerstick point-of-care troponin testing, in ruling out acute coronary syndrome.

BACKGROUND: The HEART score is a validated risk stratification tool for chest pain patients presenting to the emergency department and was recently investigated for implementation in a pre-hospital setting. Fingerstick (capillary blood) point-of-care (POC) troponin testing enables quick measurements outside the hospital and seems easier to implement than the current venous blood sampling techniques. This study investigates the diagnostic accuracy of the modified HEART score, integrating fingerstick POC troponin testing, in ruling out acute coronary syndrome (ACS). METHODS: The data of 96 patients with chest pain, included in a study investigating a novel POC troponin device under development at the cardiac emergency department, were analysed retrospectively. Based on the patients' admission data and capillary POC high-sensitivity troponin I (hs-cTnI) results, the modified HEART score was determined. The outcome measure, for evaluating the diagnostic accuracy of the modified HEART score, was the occurrence of ACS. RESULTS: Of the total study population, 33 patients (34%) were diagnosed with ACS. Seventeen patients (18%) were classified as low risk (0-3 points) and one patient (6%) in this group was diagnosed with ACS. The sensitivity and negative predictive value of the modified HEART score was 97.0 and 97.6%, respectively. CONCLUSION: The modified HEART score, integrating capillary POC hs-cTnI results, is a promising tool for ruling out ACS in patients with chest pain presenting to the cardiac emergency department. These results encourage prospective investigation into the integration of fingerstick POC troponin testing in the modified HEART score in a pre-hospital setting.
