Triggers have been developed internationally to identify intensive care patients with palliative care needs. Due to their work, nurses are close to the patient and their perspective should therefore be included. In this study, potential triggers were first identified and then a questionnaire was developed to analyse their acceptance among German intensive care nurses.
For the qualitative part of this mixed methods study, focus groups were conducted with intensive care nurses from different disciplines (surgery, neurosurgery, internal medicine), which were selected by convenience. Data were analysed using the \"content-structuring content analysis\" according to Kuckartz. For the quantitative study part, the thus identified triggers formed the basis for questionnaire items. The questionnaire was tested for comprehensibility in cognitive pretests and for feasibility in a pilot survey.
In the qualitative part six focus groups were conducted at four university hospitals. From the data four main categories (prognosis, interprofessional cooperation, relatives, patients) with three to 15 subcategories each could be identified. The nurses described situations requiring palliative care consults that related to the severity of the disease, the therapeutic course, communication within the team and between team and patient/relatives, and typical characteristics of patients and relatives. In addition, a professional conflict between nurses and physicians emerged. The questionnaire, which was developed after six cognitive interviews, consists of 32 items plus one open question. The pilot had a response rate of 76.7% (23/30), whereby 30 triggers were accepted with an agreement of ≥ 50%.
Intensive care nurses see various triggers, with interprofessional collaboration and the patient\'s prognosis playing a major role. The questionnaire can be used for further surveys, e.g. interprofessional triggers could be developed.

UNASSIGNED: Patent foramen ovale (PFO) is a congenital anatomical variant which is associated with strokes in young adults. Contrary to vascular risk factors and atherosclerosis, a PFO is present from birth. However, it is completely unknown how an anatomical structure that is already present at birth in a large proportion of the population can convert into a PFO that causes stroke in a few. Recent studies reported a significant association between certain trigger factors and ischemic stroke in young adults. This study aims to investigate these triggers in PFO-associated stroke.
UNASSIGNED: The ODYSSEY study, a multicenter prospective cohort study between 2013 and 2021, included patients aged 18-49 years experiencing their first-ever ischemic event. Participants completed a questionnaire about exposure to potential trigger factors. A case-crossover design was used to assess the relative risks (RR) with 95% confidence intervals (95% CI). The primary outcome was the RR of potential trigger factors for PFO-associated stroke.
UNASSIGNED: Overall, 1043 patients completed the questionnaire and had an ischemic stroke, of which 124 patients had a PFO-associated stroke (median age 42.1 years, 45.2% men). For patients with PFO-associated stroke, the RR was 26.0 (95% CI 8.0-128.2) for fever, 24.2 (95% CI 8.5-68.7) for flu-like disease, and 3.31 (95% CI 2.2-5.1) for vigorous exercise.
UNASSIGNED: In conclusion, flu-like disease, fever, and vigorous exercise may convert an asymptomatic PFO into a stroke-causing PFO in young adults.
UNASSIGNED: The raw and anonymized data used in this study can be made available to other researchers on request. Written proposals can be addressed to the corresponding author and will be assessed by the ODYSSEY investigators for appropriateness of use, and a data sharing agreement in accordance with Dutch regulations will be put in place before data are shared.

Migraine and epilepsy are two episodic disorders that share common pathophysiological mechanisms. The aim of our research was to assess the possible shared etiopathogenesis by analyzing the relations of headache, and seizure triggers, based on information obtained from a national cohort surveying the headache characteristics of 809 patients who had been diagnosed with idiopathic/genetic epilepsy.
Our study utilized data from a multi-center, nationwide investigation of headaches in 809 patients with idiopathic/genetic epilepsy. Out of these, 508 patients reported complaints related to any type of headache (333 Migraines, 175 Headaches of other types). In the initial phase of the study encompassing the entire sample of 809 epilepsy patients, differences in seizure triggers were assessed between the migraine group (n = 333) and the non-migraine group (n = 476). Additionally, the subsequent part of the study pertains to a subgroup of the entire patient group, namely those affected by all types of headaches (n = 508), and differences in headache triggers were assessed among migraine patients (n = 333) and those with other types of headaches (n = 175). Similar differences were observed between epilepsy patients with and without a family history of epilepsy.
The most frequently reported seizure triggers in all I/GE group (n = 809) were stress (23%), sleep deprivation (22%) and fatigue (18%), respectively. The most frequently reported headache triggers in migraine patients were stress (31%), sleep deprivation (28%), and noise (26%). The occurrence of menstruation-triggered seizures in individuals with migraine and I/GE was found to be considerably higher than those without migraine. The most common triggers for seizure and headache among the individuals with a positive family history of epilepsy were determined to be light stimuli and sleep deprivation.
In conclusion, our study provides valuable insights into the overlapping triggers including sleep patterns, stress levels, and menstrual cycles, etc. and potential shared etiology of migraine and I/GE. Recognizing these connections may facilitate the development of more precise therapeutic strategies and underscore the significance of adopting a holistic, multidisciplinary approach to the management of these intricate neurological conditions. Further research is essential to explore in greater depth the shared mechanisms underpinning these associations and their implications for clinical practice.

OBJECTIVE: While the clinical hallmarks of transient global amnesia (TGA) are well defined, its pathophysiological causes are poorly understood. Specifically, risk factors for recurrences are yet to be determined.
METHODS: This retrospective study analyzed TGA cases diagnosed and treated within the TEMPiS telestroke network and a university stroke center in Germany. Demographic and clinical data were assessed and characteristics of TGA episodes were recorded, such as season of occurrence, trigger factors, duration, and concomitant symptoms. Follow-up of the potential recurrence of TGA was performed using a standardized questionnaire.
RESULTS: Overall 109 patients were included (age 64±8 years [mean±SD], 59.6% female). The most common vascular risk factor was arterial hypertension (60.6%), and other concomitant conditions included migraine (11.9%), hypothyroidism (22.9%), and atrial fibrillation (4.6%). The most frequent concomitant clinical feature accompanying the TGA episode at admission was elevated blood pressure (48.6%). Nineteen patients experienced at least one recurrent TGA episode. Migraine and hypothyroidism were only observed in subjects with a single TGA episode without recurrence (migraine: 14.4% without recurrence vs. none in the recurrence group, p=0.02; hypothyroidism: 27.8% without recurrence vs. none in the recurrence group, p=0.009). In contrast, atrial fibrillation was more common in subjects with TGA recurrence (p<0.001).
CONCLUSIONS: Arterial hypertension is prevalent in TGA patients, with elevated blood pressure being the most-frequent concomitant condition. In our cohort, recurrence of TGA occurred in approximately one-fifth of patients. Concomitant conditions such as migraine, hypothyroidism, and atrial fibrillation occurred at different frequencies in the two groups.

UNASSIGNED: Numerous triggers have been implicated in adult female acne including endogenous (hormonal dysfunction and genetic predisposition) and exogenous causes (drugs, cosmetics, sunscreens, stress, and smoking).
UNASSIGNED: To evaluate the role of various trigger factors in adult female acne and to analyze the androgenic hormone pattern including anti-Mullerian hormone (AMH) in these patients.
UNASSIGNED: Patients having acne of age ≥25 years were analyzed using a pre devised proforma to elicit trigger factors while the severity was graded using the Global Acne Grading System (GAGS). A detailed hormonal assessment was undertaken that assessed total testosterone (TT), sex hormone-binding globulin (SHBG), free androgen index (FAI), AMH, 17-hydroxyprogesterone (17-OHP), dehydroepiandrosterone sulfate (DHEAS), follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), and prolactin.
UNASSIGNED: Out of the 165 cases seen and sub-analyzed for triggers, premenstrual flare, diet, cosmetics, and stress were the most commonly implicated causes. Among cosmetics, fairness creams and foundations were implicated. The hormonal analysis revealed deranged values of all hormones with the most common being 17-OHP and AMH. Almost 42.8% patients with DHEAS derangement and 58.75% females with raised 17-OHP suffered from moderate to severe stress.
UNASSIGNED: A prospective cohort correlation study of the implicated triggers is needed to confirm the association with adult female acne.
UNASSIGNED: Adult female acne may be triggered by diet, stress, and cosmetics and there is a distinct hormonal milieu that accounts for hyperandrogenemia. We noted high levels of adrenal androgens which have been known to be associated with stress and sleep deprivation. Our study shows the value of counseling adult female acne patients about various acne triggers.

BACKGROUND: Psychopathology and personality traits may influence the course of autoimmune disorders. With this prospective longitudinal cohort study, we aimed to assess personality, stress and depression in myasthenia patients who relapse and those who remain stable or improve (non-relapsers).
METHODS: We collected data from 155 consecutive adult patients with confirmed MG attending the Neuromuscular Clinic, Toronto General Hospital, between March 2017 and July 2018, for this study. Patients were assessed at baseline and 6 months, or at the time of MG relapse. At both visits, the patients were assessed clinically and were asked to complete self-administered questionnaires for disease severity, chronic stress and depression. Personality type was assessed at baseline only. Relapsing patients were defined as those patients with MGII score increasing by more than 5.5 points from visit 1 to visit 2.
RESULTS: Relapsers had higher baseline scores for depression (p = 0.01) and the change in disease severity correlated with the change in depression score (r = 0.2534, p = 0.0015, 95% CI: 0.098 0.3961). Higher levels of stress at baseline and neuroticism predicted higher relapse rates (p = 0.01 and p < .0001, respectively). In the linear regression model, with change of the MGII score as the dependent variable, change in depression scores (p = 0.0004) and age (p = 0.03) predicted change in disease severity.
CONCLUSIONS: Since emotional factors and personality type may influence MG, attention to these factors might improve care in MG patients.

BACKGROUND: Previous studies have reported that around 50% of patients with venous thromboembolism (VTE) has undergone recent hospitalization. However, studies on the impact of hospitalization as a trigger factor for VTE are limited.
OBJECTIVE: To investigate the impact of hospitalization with and without concurrent immobilization as a trigger factor for VTE.
METHODS: We conducted a case-crossover study of 530 cancer-free VTE patients. Hospitalizations were registered during the 90-day period preceding the VTE diagnosis (hazard period), and in four preceding 90-day control periods. A 90-day washout period between the control- and hazard periods was implemented to avoid potential carry-over effects. Conditional logistic regression was used to calculate odds ratios (OR) of VTE according to hospitalization.
RESULTS: In total, 159 (30%) of the VTE-patients had been hospitalized in the hazard period, and the OR of hospitalization was 9.4 (95% CI: 6.8-12.8). The risk increased slightly with the total number of days spent in hospital (OR per day: 1.11, 95% CI: 1.04-1.18), and with the number of hospitalizations (OR 8.9, 95% CI: 6.4-12.4 for 1 hospitalization and OR 12.3, 95% CI 6.4-23.6 for ≥2 hospitalizations). Hospitalization without immobilization was 6-times (OR: 6.3, 95% CI: 4.4-9.2) more common, whereas hospitalization with immobilization was near 20-times (OR: 19.8, 95% CI: 11.5-34.0) more common in the 90-days prior to a VTE compared to the control periods.
CONCLUSIONS: Hospitalization is a major trigger factor for VTE also in the absence of immobilization. However, immobilization contributes substantially to the risk of VTE among hospitalized patients.

BACKGROUND: It is important to identify factors that influence the risk of relapses in inflammatory bowel disease. Few studies have been conducted and with limited methodology. This prospective case-crossover study, aims to examine whether perceived stress has a short-term acute effect, namely whether it acts as a trigger, on the risk of relapse in inflammatory bowel disease.
METHODS: Sixty patients with inflammatory bowel disease and in remission were included. The case-crossover design was employed, which is an epidemiological design developed to study triggers for acute events and diseases. To collect information regarding symptoms and potential trigger factors, such as perceived stress, a structured diary was constructed. The participants were instructed to fill in the diary daily during six months. Fifty patients completed the study.
RESULTS: The analysis showed an effect for high level of perceived stress. Being exposed to \"quite a lot\" of stress, yield an increase in risk for relapse during the forthcoming day (OR = 4.8, 95% CI 1.09 - 21.10). No statistically increased risk for lower levels of perceived stress was found, although elevated effect estimates were found for \"some\" stress.
CONCLUSIONS: This study supports earlier findings regarding perceived stress as an important factor in triggering relapses in IBD. However, this is the first case-crossover study performed to explore the trigger risk of stress in this population. Further investigations with larger patient samples are needed to confirm the findings.

OBJECTIVE: Numerous lifestyle factors are blamed for triggering migraine attacks. The reliability of assessing these factors retrospectively is unknown. Therefore, retrospective and prospective assessments of lifestyle in general and of migraine triggers in particular were compared in patients with migraine.
METHODS: At baseline, the patients filled in two questionnaires covering the previous 90 days. Thereafter they kept a prospective 90-day diary. Questionnaires and diary included the same set of 45 factors. In the first questionnaire the patients assessed their lifestyle, in the second they rated for each factor the likelihood of triggering a migraine attack, and in the diary they recorded the daily presence of these factors irrespective of headache. Five categories were used for comparing frequencies in questionnaire and diary, defining agreement as identical categories in diary and questionnaire, minor disagreement and major disagreement as overestimation or underestimation by one category and two or more categories, respectively.
RESULTS: In all, 327 patients (283 women, age 41.9 ± 12.1 years) who recorded 28,325 patient days were included. Calculating for each factor the percentage of patients with major disagreement the mean proportion was larger for trigger factors than for lifestyle (38.7% ± 6.6% vs. 16.9% ± 6.4%, P < 0.001). The proportion of factors showing major disagreement in more than 20% of the patients was 8.8% for lifestyle but 94.1% for trigger factors (P < 0.001).
CONCLUSIONS: Comparing questionnaire and diary assessments of lifestyle and trigger factors in patients with migraine shows that questionnaire assessment of lifestyle is reliable, whereas trigger factors are overestimated and/or underestimated in retrospective questionnaires.
