The linguistic validation of the gut feelings questionnaire in Turkish.

Background: 'Gut feelings' are frequently used by general practitioners in the clinical decision-making process, especially in situations of uncertainty. The Gut Feelings Questionnaire (GFQ) has been developed in the Netherlands and is now available in English, French, German, Polish, Spanish, and Catalan, enabling cross-border studies on the subject. However, a Turkish version of the GFQ is lacking.

How patients in general practice voice and value their gut feelings about health: a qualitative interview study.

Background: GPs consider their gut feelings a valuable tool in clinical reasoning. Research suggests patients' gut feelings may be a useful contribution to that process. Describing these feelings more precisely could improve primary care professionals' (PCPs) recognition of patients' gut feelings and insight into the underlying reasons.

Prospective Observational Study on the Prevalence and Diagnostic Value of General Practitioners' Gut Feelings for Cancer and Serious Diseases.

Background: General practitioners (GPs) have recognized the presence of gut feelings in their diagnostic process. However, little is known about the frequency or determinants of gut feelings or the diagnostic value of gut feelings for cancer and other serious diseases.

Objective: To assess the prevalence of gut feelings in general practice, examine their determinants and impact on patient management, and measure their diagnostic value for cancer and other serious diseases.

Embracing complexity with systems thinking in general practitioners' clinical reasoning helps handling uncertainty.

Clinical reasoning in general practice is increasingly challenging because of the rise in the number of patients with multimorbidity. This creates uncertainty because of unpredictable interactions between the symptoms from multiple medical problems and the patient's personality, psychosocial context and life history. Case analysis may then be more appropriately managed by systems thinking than by hypothetic-deductive reasoning, the predominant paradigm in the current teaching of clinical reasoning.

How child health care physicians struggle from gut feelings to managing suspicions of child abuse.

Aim: We examined how gut feelings of child health care physicians' (CHCPs) contribute to the development of a suspicion of child abuse, how they act upon this suspicion and what barriers they experience in their management. To gain insight into the youth health care chain, we compared the diagnostic reasoning and management regarding this issue by CHCPs and family physicians (FPs).

Methods: Three focus groups, 20 CHCPs, thematic content analysis.

[Medical disciplinary boards on gut feelings].

Dutch medical disciplinary boards consider physicians' gut feelings an element of the professional standards. Some indications can be found in the international literature suggesting intuitive feelings of unease of patients or their relatives can also contribute to adequate diagnostics. What is the view of disciplinary boards on this? A search in the disciplinary boards' database (2010-2017) found 55 rulings where the search term 'ongerust' (worried) was related to a patient, family member or partner and 51 rulings where the term 'bezorgd' (concerned) was related to a patient, family member or partner.

GPs' suspicion of child abuse: how does it arise and what is the follow-up?

Child abuse is widespread, occurs in all cultures and communities, remains undiscovered in 90% of cases and has serious long-term effects. Physicians generally underidentify and underreport child abuse. To understand this low reporting rate and how the suspicion of child abuse arises, we examined GPs' experiences.

Accuracy of the general practitioner's sense of alarm when confronted with dyspnoea and/or chest pain: a prospective observational study.

Objectives: Dyspnoea and chest pain are symptoms shared with multiple pathologies ranging from the benign to life-threatening diseases. A Gut Feelings Questionnaire (GFQ) has been validated to measure the general practitioner's (GPs) sense of alarm or sense of reassurance. The aim of the study was to estimate the diagnostic test accuracy of GPs' sense of alarm when confronted with dyspnoea and chest pain.

Prevalence and diagnostic value of GPs' gut feelings for cancer and serious diseases: protocol for a prospective observational study of diagnostic validity.

Introduction: Cancer diagnosis in primary care is an important challenge for general practitioners (GPs) due to the relatively low frequency of any single type of cancer and the heterogeneous signs and symptoms that can be present. In addition to analytical reasoning, GPs may become aware of gut feelings (GFs) as they suspect that a patient may have cancer or another serious disease. We aimed to investigate the prevalence and the predictive value of GFs for the diagnosis of cancer and serious diseases.

Role of intuitive knowledge in the diagnostic reasoning of hospital specialists: a focus group study.

Background And Objective: Intuition is an important part of human decision-making and can be explained by the dual-process theory where analytical and non-analytical reasoning processes continually interact. These processes can also be identified in physicians' diagnostic reasoning. The valuable role of intuition, including gut feelings, has been shown among general practitioners and nurses, but less is known about its role among hospital specialists.

Gut Feelings Questionnaire in daily practice: a feasibility study using a mixed-methods approach in three European countries.

Objectives: The validated Gut Feelings Questionnaire (GFQ) is a 10-item questionnaire based on the definitions of the sense of alarm and the sense of reassurance. The purpose of the GFQ is to determine the presence or absence of gut feelings in the diagnostic reasoning of general practitioners (GPs).The aim was to test the GFQ on GPs, in real practice settings, to check whether any changes were needed to improve feasibility, and to calculate the prevalence of the GPs' sense of alarm and sense of reassurance in three different countries.

Cross-cultural translation and validation of the 'gut feelings' questionnaire into Spanish and Catalan.

Background: The gut feelings questionnaire (GFQ) is the only tool developed to assess the presence of a 'sense of alarm' or a 'sense of reassurance' in the diagnostic process of general practitioners (GPs). It was created in Dutch and English and has validated versions in French, German and Polish.

Objectives: To obtain a cross-cultural translation of the GFQ into Spanish and Catalan and to assess the structural properties of the translated versions.

Redox variations in Mauna Kea lavas, the oxygen fugacity of the Hawaiian plume, and the role of volcanic gases in Earth's oxygenation.

The behavior of C, H, and S in the solid Earth depends on their oxidation states, which are related to oxygen fugacity (O). Volcanic degassing is a source of these elements to Earth's surface; therefore, variations in mantle O may influence the O at Earth's surface. However, degassing can impact magmatic O before or during eruption, potentially obscuring relationships between the O of the solid Earth and of emitted gases and their impact on surface O We show that low-pressure degassing resulted in reduction of the O of Mauna Kea magmas by more than an order of magnitude.

The effect of liquid composition on the partitioning of Ni between olivine and silicate melt.

We report the results of experiments designed to separate the effects of temperature and pressure from liquid composition on the partitioning of Ni between olivine and liquid, [Formula: see text]. Experiments were performed from 1300 to 1600 °C and 1 atm to 3.0 GPa, using mid-ocean ridge basalt (MORB) glass surrounded by powdered olivine in graphite-Pt double capsules at high pressure and powdered MORB in crucibles fabricated from single crystals of San Carlos olivine at one atmosphere.

Gut feelings in the diagnostic process of Spanish GPs: a focus group study.

Objectives: The gut feelings of doctors can act as triggers and modulators of the diagnostic process. This study explored the existence, significance, determinants and triggers of gut feelings among Spanish general practitioners.

Design: Qualitative study using focus groups.

Silicic volcanism on Mars evidenced by tridymite in high-SiO2 sedimentary rock at Gale crater.

Tridymite, a low-pressure, high-temperature (>870 °C) SiO2 polymorph, was detected in a drill sample of laminated mudstone (Buckskin) at Marias Pass in Gale crater, Mars, by the Chemistry and Mineralogy X-ray diffraction instrument onboard the Mars Science Laboratory rover Curiosity The tridymitic mudstone has ∼40 wt.% crystalline and ∼60 wt.% X-ray amorphous material and a bulk composition with ∼74 wt.

Mineralogy, provenance, and diagenesis of a potassic basaltic sandstone on Mars: CheMin X-ray diffraction of the Windjana sample (Kimberley area, Gale Crater).

The Windjana drill sample, a sandstone of the Dillinger member (Kimberley formation, Gale Crater, Mars), was analyzed by CheMin X-ray diffraction (XRD) in the MSL Curiosity rover. From Rietveld refinements of its XRD pattern, Windjana contains the following: sanidine (21% weight, ~Or); augite (20%); magnetite (12%); pigeonite; olivine; plagioclase; amorphous and smectitic material (~25%); and percent levels of others including ilmenite, fluorapatite, and bassanite. From mass balance on the Alpha Proton X-ray Spectrometer (APXS) chemical analysis, the amorphous material is Fe rich with nearly no other cations-like ferrihydrite.

The chlorine isotope fingerprint of the lunar magma ocean.

The Moon contains chlorine that is isotopically unlike that of any other body yet studied in the Solar System, an observation that has been interpreted to support traditional models of the formation of a nominally hydrogen-free ("dry") Moon. We have analyzed abundances and isotopic compositions of Cl and H in lunar mare basalts, and find little evidence that anhydrous lava outgassing was important in generating chlorine isotope anomalies, because (37)Cl/(35)Cl ratios are not related to Cl abundance, H abundance, or D/H ratios in a manner consistent with the lava-outgassing hypothesis. Instead, (37)Cl/(35)Cl correlates positively with Cl abundance in apatite, as well as with whole-rock Th abundances and La/Lu ratios, suggesting that the high (37)Cl/(35)Cl in lunar basalts is inherited from urKREEP, the last dregs of the lunar magma ocean.

The accuracy of the general practitioner's sense of alarm when confronted with dyspnoea and/or thoracic pain: protocol for a prospective observational study.

Introduction: Dyspnoea and chest pain are signs shared with multiple pathologies ranging from the benign to life-threatening diseases. Gut feelings such as the sense of alarm and the sense of reassurance are known to play a substantial role in the diagnostic reasoning of general practitioners (GPs). A Gut Feelings Questionnaire (GFQ) has been validated to measure the GP's sense of alarm.

"I can't find anything wrong: it must be a pulmonary embolism": Diagnosing suspected pulmonary embolism in primary care, a qualitative study.

Background: Before using any prediction rule oriented towards pulmonary embolism (PE), family physicians (FPs) should have some suspicion of this diagnosis. The diagnostic reasoning process leading to the suspicion of PE is not well described in primary care.

Objective: to explore the diagnostic reasoning of FPs when pulmonary embolism is suspected.

Volatile and organic compositions of sedimentary rocks in Yellowknife Bay, Gale crater, Mars.

H2O, CO2, SO2, O2, H2, H2S, HCl, chlorinated hydrocarbons, NO, and other trace gases were evolved during pyrolysis of two mudstone samples acquired by the Curiosity rover at Yellowknife Bay within Gale crater, Mars. H2O/OH-bearing phases included 2:1 phyllosilicate(s), bassanite, akaganeite, and amorphous materials. Thermal decomposition of carbonates and combustion of organic materials are candidate sources for the CO2.

Elemental geochemistry of sedimentary rocks at Yellowknife Bay, Gale crater, Mars.

Sedimentary rocks examined by the Curiosity rover at Yellowknife Bay, Mars, were derived from sources that evolved from an approximately average martian crustal composition to one influenced by alkaline basalts. No evidence of chemical weathering is preserved, indicating arid, possibly cold, paleoclimates and rapid erosion and deposition. The absence of predicted geochemical variations indicates that magnetite and phyllosilicates formed by diagenesis under low-temperature, circumneutral pH, rock-dominated aqueous conditions.

In situ radiometric and exposure age dating of the martian surface.

We determined radiogenic and cosmogenic noble gases in a mudstone on the floor of Gale Crater. A K-Ar age of 4.21 ± 0.
