- Aim: To evaluate measurements of intragastric pH with the Bravo capsule system over a prolonged time. Methods: A Bravo capsule was placed inside the rat gastric body and pH was studied for periods up to five consecutive. days. For comparison, a gastric fistula model was used. Effects of ghrelin and esomeprazole, with or without pentagastrin, on gastric pH were studied. In addition, effects of esomeprazole on plasma ghrelin, gastrin and somatostatin were analyzed. Results: All rats recovered after surgery. The average 24-h pH during free feeding was 2.3 +/- 0.1 (n = 20) with a variation of 18% +/- 6% over 5 d. Ghrelin, 2400 pmol/kg, t.i.d. increased pH from 1.7 +/- 0.1 to 3.1 +/- 0.3 (P < 0.01) as recorded with the Bravo system. After esomeprazole (1 mg/kg, 3 mg/kg and 5 mg/kg) there was a dose-dependent pH increase of maximally 3.4 +/- 0.1, with day-to-day variation over the entire period of 8% +/- 3%. The fistula and pH studies generated similar results. Acid inhibition with esomeprazole increased plasma ghrelin from 10 +/- 2 pmol/L to 65 +/- 26 pmol/L (P < 0.001), and somatostatin from 10 +/- 2 pmol/L to 67 +/- 18 pmol/L (P < 0.001). Conclusion: pH measurements with the Bravo capsule are reliable, and comparable to those of the gastric fistula model. The Bravo system optimizes accurate intragastric pH monitoring over prolonged periods and allows both short- and long-term evaluation of effects of drugs and hormones.

- The impact of exposure of the intestinal mucosa to acid and hyperosmolal solutions on the release of the inhibitory gut peptides somatostatin (SOM), neurotensin (NT) and vasoactive intestinal peptide (VIP) was studied in conscious rats during pentagastrin-stimulated gastric acid secretion. The animals were equipped with a chronic gastric fistula to measure acid secretion and a jejunal Thiry-Vella loop for intestinal challenge with saline, hydrochloric acid (HCl, 200 mmol L-1) or hyperosmolal polyethylene glycol (PEG, 1200 mOsm kg(-1)). Gut peptide concentrations were measured in intestinal perfusates, and in plasma samples collected during stimulated acid secretion, and at the end of experiments with luminal challenge of the loops. After pentagastrin-stimulation acid secretion was dose-dependently inhibited by intravenous administration of the gastrin receptor antagonist gastrazole, as well as ranitidine and esomeprazole by maximally 73 +/- 10%; 95 +/- 3%; 90 10%, respectively. Acid perfusion of the Thiry-Vella loop caused a prominent release of SOM both to the lumen (from 7.2 +/- 5.0 to 1279 +/- 580 pmol L-1) and to the circulation (from 18 +/- 5.2 to 51 +/- 9.0 pmol L-1) simultaneously with an inhibition of gastric acid secretion. The release of NTand VIP was not affected to the same extent. PEG perfusion of the loop caused a release of SOM as well as NT and VIP, but less. Simultaneously acid secretion was slightly decreased. In conclusion, intestinal perfusion with acid or hyperosmolal solutions mainly releases SOM, which seems to exert a major inhibitory action in the gut, as shown by inhibition of acid secretion. The other peptides NT and VIP also participate in this action but to a much lesser degree. The operative pathways of these gut peptides hence involve both endocrine (SOM) and paracrine actions (SOM, NT, VIP) in order to exert inhibitory functions on the stomach. The inhibitory action of gastrazole, was in a similar range as that of SOM implying that physiological acid-induced inhibition of gastric acid may primarily be exerted through inhibition of gastrin endocrine secretion.

- Aim: To describe how children in Sweden accessed and perceived information about SARS-CoV2 and Covid-19 during the first phase of the outbreak. Methods: This study is a substudy of an international cross-sectional online mixed methods survey examining elements of children's health literacy in relation to Covid-19. The survey included multiple-choice questions, open-ended questions and drawings and collected information from 50 Swedish children (7-12 years). Data were analysed concurrently on a descriptive level using statistics and content analysis. Quantitative and qualitative data, including the drawings, were considered equally important and resulted in six categories, illuminating how children accessed and perceived information about the pandemic. Results: The survey showed that children accessed information mainly from school but also from TV. They preferred information from reliable sources. Children reported the information they accessed as easy to understand and it prompted them to ask new questions. They reported they knew a lot about the pandemic, for example, the potential danger to themselves and others and how to act to protect themselves and others. They perceived the pandemic as an intrusion on their lives. Conclusions: This study indicates that Swedish children between 7 and 12 years old were well informed about SARS-CoV2 and Covid-19 during the first phase of the pandemic. School was shown to be an important source of information. The children could explain how to act to protect themselves and others from becoming infected by the virus.

- When the mouth is affected by cancer, difficulties in satisfying basic human needs such as eating, tasting, swallowing, and speaking might arise, and the existential significance of the mouth might become obvious. How does it feel to live with these difficulties? What does it mean to be a human being living with the consequences of oral cancer? Five patients with oral cancer were interviewed a median time of 4 years after the beginning of treatment. A hermeneutic research approach was used to understand, explain, and interpret the transcribed interviews and showed how the consequences of oral cancer affected the being-in-the-world of the participants in three ways: existing as oneself, existing in the eyes of others, and existing with others. Against the background of the philosophy of Martin Heidegger, these findings illuminate how essential the mouth is to a human being's identity and existence.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Globally, critical illness results in millions of deaths every year. Although many of these deaths are potentially preventable, the basic, life-saving care of critically ill patients are often overlooked in health systems. Essential Emergency and Critical Care (EECC) has been devised as the care that should be provided to all critically ill patients in all hospitals in the world. EECC includes the effective care of low cost and low complexity for the identification and treatment of critically ill patients across all medical specialties. This study aimed to specify the content of EECC and additionally, given the surge of critical illness in the ongoing pandemic, the essential diagnosis-specific care for critically ill patients with COVID-19.METHODS: In a Delphi process, consensus (>90% agreement) was sought from a diverse panel of global clinical experts. The panel iteratively rated proposed treatments and actions based on previous guidelines and the WHO/ICRC's Basic Emergency Care. The output from the Delphi was adapted iteratively with specialist reviewers into a coherent and feasible package of clinical processes plus a list of hospital readiness requirements.RESULTS: The 269 experts in the Delphi panel had clinical experience in different acute medical specialties from 59 countries and from all resource settings. The agreed EECC package contains 40 clinical processes and 67 requirements, plus additions specific for COVID-19.CONCLUSION: The study has specified the content of care that should be provided to all critically ill patients. Implementing EECC could be an effective strategy for policy makers to reduce preventable deaths worldwide.

- A high proportion of refugees have been subjected to potentially traumatic experiences (PTEs), including torture. PTEs, and torture in particular, are powerful predictors of mental ill health. This paper reports the development and preliminary validation of a brief refugee trauma checklist applicable for survey studies.Methods: A pool of 232 items was generated based on pre-existing instruments. Conceptualization, item selection and item refinement was conducted based on existing literature and in collaboration with experts. Ten cognitive interviews using a Think Aloud Protocol (TAP) were performed in a clinical setting, and field testing of the proposed checklist was performed in a total sample of n = 137 asylum seekers from Syria.Results: The proposed refugee trauma history checklist (RTHC) consists of 2 × 8 items, concerning PTEs that occurred before and during the respondents' flight, respectively. Results show low item non-response and adequate psychometric propertiesConclusion: RTHC is a usable tool for providing self-report data on refugee trauma history surveys of community samples. The core set of included events can be augmented and slight modifications can be applied to RTHC for use also in other refugee populations and settings.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Undocumented migrants in Sweden have no regulated access to health care, but as legislation forbids anyone to be denied “immediate” care at their own expense when in need, this applies also to them. In lack of specific national regulations, local policies on the issue have been formed. This study, based on interviews with civil servants on the local levels and representatives of NGO clinics as well as the study of relevant national legislation and local policies, concludes that the local policies formed may be categorized into three groups: regulations that merely clarify the implications of current national legislation, regulations that incorporates the group “undocumented migrants” in “asylum seekers” and equates their entitlements, and finally, regulations that widen undocumented migrants’ access to health care from ”immediate” care to also include ”immediately necessary” care. These ambiguities put a heavy responsibility on the individual practitioner, and clearer, well-communicated regulations would help solve this situation.

- Absence and presence have generally been discussed as two aspects of either a temporal or a spatial relationship. With an Arendtian notion of presence as the capacity to define space and to appear in front of others, this article explores undocumentedness as a condition of simultaneous presence and absence. Drawing on ethnographic fieldwork and interviews with undocumented persons in Sweden, it is argued that the undocumented spatiality is paradoxical and Möbius. This article shows how concealment, disguise, diffusion and appearance are key to the different manifestations of presence and absence in undocumented people’s lives. It also shows how undocumented persons, by using their politically absent yet physically present bodies as vehicles for practicing dissensus, can find possibilities for recognition and action in public space.
