Exogenous glucagon-like peptide 2 counteracts exogenous cholecystokinin-induced gallbladder contraction in healthy men.

BACKGROUND AND OBJECTIVE: Studies in humans and mice have demonstrated that the gut hormone glucagon-like peptide 2 (GLP-2) promotes gallbladder relaxation and refilling. Here, we assessed the effect of exogenous GLP-2 on gallbladder motility in the fasted state of healthy men with and without infusion of the potent gallbladder-contracting hormone cholecystokinin (CCK). METHODS: In a randomized, double-blind, placebo-controlled, crossover study, 15 male participants (mean [SD]: age 24.7 [3.6] years; body mass index 22.9 [1.6] kg/m2) underwent four experimental days receiving two infusions on each day: either CCK (0.4 pmol × kg-1 × min-1, time 0-180 min) + GLP-2 (10 pmol × kg-1 × min-1, time 30-240 min), CCK + placebo, placebo + GLP-2, or placebo + placebo, respectively. Gallbladder volume was measured at baseline and throughout the 4-hour study day using ultrasonography. RESULTS: Compared to placebo + placebo, GLP-2 + placebo did not affect gallbladder volume, but when infused in combination with CCK, GLP-2 completely abolished the strong gallbladder-contracting effect seen during CCK + placebo infusion, restoring baseline levels of gallbladder volume. CONCLUSION: Exogenous GLP-2 counteracts exogenous CCK-induced gallbladder emptying in healthy men, pointing to a possible therapeutic potential for GLP-2 as a relaxing modulator of gallbladder smooth muscle tone (e.g., as bridge to surgery in biliary colic). The effect may also explain the gallbladder-related adverse events reported for GLP-2 receptor agonists used in the treatment of short bowel syndrome.

Translation and validation of the Hirschsprung and anorectal malformation quality of life (HAQL) questionnaire in a Danish Hirschsprung population.

BACKGROUND: Hirschsprung's disease (HD) may result in an impaired quality of life (QoL) due to bowel problems, postoperative complications and other health-related issues. The Hirschsprung and Anorectal Malformation Quality of Life (HAQL) questionnaire is a disease-specific instrument developed in the Netherlands to measure the QoL in patients with HD and anorectal malformations. The aim of this study was to translate, culturally adapt and validate HAQL in a Danish Hirschsprung population. MATERIAL AND METHODS: Translation and cultural adaptation were performed according to international guidelines. Invitations to participate in the validation were sent to 401 patients operated for HD during the period from 1985 to 2012. A total of 156 patients completed the translated and culturally adapted Danish versions of HAQL and 35 parents of children and adolescents completed the corresponding parent questionnaire. Reliability was evaluated in terms of internal consistency using Cronbach's α and test-retest reliability using Intraclass Correlation Coefficient for the retest step. Known groups comparison was performed with comparison of mild HD (defined as recto-sigmoidal HD) and serious HD (defined as more proximal disease). RESULTS: The internal consistency of the dimensions was overall satisfactory for adults and adolescents but more problematic for children, where Cronbach's α was less than 0.7 in 60% of the dimensions. For both children and adolescents, the α-value was unsatisfactory for social functioning, emotional functioning, and body image. The test-retest reliability was overall good. The known groups comparison was only able to demonstrate a significant difference between mild and severe HD within one dimension. CONCLUSIONS: The translated version of the HAQL questionnaires provides an overall reliable instrument for evaluating disease-specific QoL in a Danish HD population, but it is important to acknowledge the limitations of the questionnaire, especially in children and adolescents.

Pancultural nostalgia in action: Prevalence, triggers, and psychological functions of nostalgia across cultures.

Nostalgia is a social, self-relevant, and bittersweet (although mostly positive) emotion that arises when reflecting on fond past memories and serves key psychological functions. The majority of evidence concerning the prevalence, triggers, and functions of nostalgia has been amassed in samples from a handful of largely Western cultures. If nostalgia is a fundamental psychological resource, it should perform similar functions across cultures, although its operational dynamics may be shaped by culture. This study (N = 2,606) examined dispositional nostalgia, self-reported triggers of nostalgia, and functions of experimentally induced nostalgia in young adults across 28 countries and a special administrative region of China (i.e., Hong Kong). Results indicated that nostalgia is frequently experienced across cultures, albeit better valued in more-developed countries (i.e., higher national wealth and life-expectancy). Nostalgia is triggered by psychological threats (especially in warmer countries), sensory stimuli (especially in more-developed countries), and social gatherings (especially in less-developed countries). The positive or negative affect prompted by experimentally induced nostalgia varied by country, but was mild overall. More importantly, recalling a nostalgic (vs. ordinary) memory increased social connectedness, self-continuity, and meaning in life across cultures. In less-developed countries, recalling an ordinary memory also conferred some of these functions, reducing the effect size of nostalgia. Finally, recalling a nostalgic (vs. ordinary) memory augmented state satisfaction with life in countries with lower quality of living (i.e., lower life-expectancy and life-satisfaction). Overall, findings confirm the relevance of nostalgia across a wide range of cultures and indicate cultural nuances in its functioning. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Combining Language Training and Work Experience for Refugees with Low-Literacy Levels: a Mixed-Methods Case Study.

Learning the host society's language and finding a job are important steps for the societal integration of refugees. Especially language proficiency is a key barrier for the integration of low literates. Often language training and gaining work skills are separated during the integration procedure. We investigated a 1-year pilot program for refugees with low-literacy levels in the Netherlands, which combined language training (daily classes, work-related language) with work experience in sheltered employment (second-hand shop) to facilitate language learning and prepare this group better for the labour market. Building on Ager and Strang's conceptual integration framework (2008), we expected that this combined program should improve agency (communication strategies, preparedness for the labour market) via intergroup contact at work. We used a mixed-method approach to follow the development of participants (N=10) longitudinally (baseline, after 6 months, after 11 months). We gathered questionnaire data, interviewed teachers and students, and observed interactions in classes and at work. Overall, use of communication strategies increased. Analyzing individual cases (profiles) offered nuanced insights into for whom and why the program seems to have differential impact, especially in terms of labour market preparation. We discuss results and the importance of creating intergroup contact to facilitate integration in a new society.

GIP reduces osteoclast activity and improves osteoblast survival in primary human bone cells.

OBJECTIVE: Drugs targeting the glucose-dependent insulinotropic polypeptide (GIP) receptor (GIPR) are emerging as treatments for type-2 diabetes and obesity. GIP acutely decreases serum markers of bone resorption and transiently increases bone formation markers in short-term clinical investigations. However, it is unknown whether GIP acts directly on bone cells to mediate these effects. Using a GIPR-specific antagonist, we aimed to assess whether GIP acts directly on primary human osteoclasts and osteoblasts. METHODS: Osteoclasts were differentiated from human CD14+ monocytes and osteoblasts from human bone. GIPR expression was determined using RNA-seq in primary human osteoclasts and in situ hybridization in human femoral bone. Osteoclastic resorptive activity was assessed using microscopy. GIPR signaling pathways in osteoclasts and osteoblasts were assessed using LANCE cAMP and AlphaLISA phosphorylation assays, intracellular calcium imaging and confocal microscopy. The bioenergetic profile of osteoclasts was evaluated using Seahorse XF-96. RESULTS: GIPR is robustly expressed in mature human osteoclasts. GIP inhibits osteoclastogenesis, delays bone resorption, and increases osteoclast apoptosis by acting upon multiple signaling pathways (Src, cAMP, Akt, p38, Akt, NFκB) to impair nuclear translocation of nuclear factor of activated T cells-1 (NFATc1) and nuclear factor-κB (NFκB). Osteoblasts also expressed GIPR, and GIP improved osteoblast survival. Decreased bone resorption and improved osteoblast survival were also observed after GIP treatment of osteoclast-osteoblast co-cultures. Antagonizing GIPR with GIP(3-30)NH2 abolished the effects of GIP on osteoclasts and osteoblasts. CONCLUSIONS: GIP inhibits bone resorption and improves survival of human osteoblasts, indicating that drugs targeting GIPR may impair bone resorption, whilst preserving bone formation.

Acarbose diminishes postprandial suppression of bone resorption in patients with type 2 diabetes.

AIMS: The alpha-glucosidase inhibitor acarbose is an antidiabetic drug delaying assimilation of carbohydrates and, thus, increasing the amount of carbohydrates in the distal parts of the intestines, which in turn increases circulating levels of the gut-derived incretin hormone glucagon-like peptide 1 (GLP-1). As GLP-1 may suppress bone resorption, acarbose has been proposed to potentiate meal-induced suppression of bone resorption. We investigated the effect of acarbose treatment on postprandial bone resorption in patients with type 2 diabetes and used the GLP-1 receptor antagonist exendin(9-39)NH2 to disclose contributory effect of acarbose-induced GLP-1 secretion. METHODS: In a randomised, placebo-controlled, double-blind, crossover study, 15 participants with metformin-treated type 2 diabetes (2 women/13 men, age 71 (57-85 years), BMI 29.7 (23.6-34.6 kg/m2), HbA1c 48 (40-74 mmol/mol)/6.5 (5.8-11.6 %) (median and range)) were subjected to two 14-day treatment periods with acarbose and placebo, respectively, separated by a six-week wash-out period. At the end of each period, circulating bone formation and resorption markers were assessed during two randomised 4-h liquid mixed meal tests (MMT) with infusions of exendin(9-39)NH2 and saline, respectively. Glucagon-like peptide 2 (GLP-2) was also assessed. RESULTS: Compared to placebo, acarbose impaired the MMT-induced suppression of CTX as assessed by baseline-subtracted area under curve (P = 0.0037) and nadir of CTX (P = 0.0128). During acarbose treatment, exendin(9-39)NH2 infusion lowered nadir of CTX compared to saline (P = 0.0344). Neither parathyroid hormone or the bone formation marker procollagen 1 intact N-terminal propeptide were affected by acarbose or GLP-1 receptor antagonism. Acarbose treatment induced a greater postprandial GLP-2 response than placebo treatment (P = 0.0479) and exendin(9-39)NH2 infusion exacerbated this (P = 0.0002). CONCLUSIONS: In patients with type 2 diabetes, treatment with acarbose reduced postprandial suppression of bone resorption. Acarbose-induced GLP-1 secretion may contribute to this phenomenon as the impairment was partially reversed by GLP-1 receptor antagonism. Also, acarbose-induced reductions in other factors reducing bone resorption, e.g. glucose-dependent insulinotropic polypeptide, may contribute.

Critical Incidents Scale for Ambulance Work - Denmark (CISAW-D): the development of a screening tool for work exposure to critical events in operative ambulance personnel.

Introduction: Critical incidents in ambulance work are not easily compared to other risk occupations. Understanding types of incidents that can be considered critical in operational ambulance work is important to prevent work-related post-traumatic stress (PTS). Aim: This study aimed to develop a scale of critical incidents in ambulance work and assess its predictive validity in relation to the severity of PTS symptoms. Methods: A total of 1092 open-ended descriptions from Danish ambulance personnel were content analysed to develop a categorical scale that identifies types of events perceived as critical to operative ambulance personnel. Multiple regression was used to assess whether the scale predicted PTS symptoms and to assess the cumulative effect of exposure to these events. Results: The study found that the 1092 descriptions of critical events could be condensed into 28 categories of critical events. These ranged from life-threatening situations and deaths, to more daily events such as handling strong emotional reactions from patients' relatives and working with terminally ill children. The frequency of events significantly predicted the severity of PTS symptoms with low to moderate effect (std beta = 0.2, t(375) = 3.7, p < .001), even when adjusting for known risk factors for post-traumatic stress disorder. Conclusion: This study showed that critical events in ambulance work included events that are not normally considered traumatic, and indicated that understanding the cumulative effect of these events is important when trying to prevent traumatic sequalae in ambulance personnel. The study highlighted the importance of increased focus on non-traumatic incidents that have an ongoing impact on paramedics' mental health and well-being. The Critical Incidents Scale for Ambulance Work - Denmark (CISAW-D) is a promising tool for systematic screening for exposure to critical events in ambulance work.

Association between Health-Related Quality of Life and Completion of First-Line Treatment among Lung Cancer Patients.

Experts recommend assessing lung cancer patients' health-related quality of life (HRQOL) in the diagnostic evaluation. We investigated the association between HRQOL and completion of first-line treatment among lung cancer patients in a prospective cohort study. Clinical information on lung cancer patients was obtained from medical records, and information on quality of life and lung cancer-related symptoms was obtained through questionnaires at time of diagnosis. We used directed acyclic graphs to identify potential confounders and mediators between HRQOL and completion of first-line treatment. The association between functioning levels and symptoms and completion of first-line oncological treatment was estimated as odds ratios, with 95% confidence intervals, in logistic regression models. In all, 137 patients (52% men, mean age: 69 years) participated, out of 216 invited. Patients who reported reduced functioning had significantly increased ORs for not completing first-line treatment: poor physical function (OR 4.44), role function (OR 6.09), emotional function (OR 5.86), and social function (OR 3.13). Patients with fatigue (OR 7.55), pain (OR 6.07), appetite loss (OR 4.66), and financial difficulties (OR 17.23) had significantly increased ORs for not completing the first-line treatment. Reduced functioning and presence of symptoms were associated with not completing first-line treatment. An assessment of HRQOL could potentially aid the diagnostic evaluation and treatment planning for lung cancer patients.

Defining Power and Agency in Gender Relations in El Salvador: Consequences for Intimate Partner Violence and Women's Mental Health.

Intimate partner violence (IPV) affects thousands of women around the world and is prevalent in the Global South. Unequal social structures perpetuate hierarchies and maintain women's vulnerability to violence. Difficulties women face in accessing education, economic resources, and employment diminish their power in intimate relationships, increasing the likelihood of IPV. These factors can also have a significant effect on women's mental health. However, some studies show that economic empowerment does not necessarily translate into greater agency for women if they cannot use the resources they earn to pursue whatever goals or values they regard as important in life. Agency is women's ability to identify their life goals and act upon them through critical evaluation (intrinsic agency) and autonomous decision-making (instrumental agency). In this article, we aim to analyze the relationship between women's power (educational and economic) and agency and their influence on intimate partner violence and on women's mental health in the context of El Salvador. Currently, El Salvador has one of the highest percentages of femicide worldwide. We used data from the first national survey on violence against women in El Salvador to determine empowerment indicators and investigated their influence on intimate partner violence and women's mental health. Results from a representative sample of 1,274 women aged between 15 and 64 years old and, using a structural equation modeling revealed that education was a protective factor against IPV, but economic power appeared to put women at greater risk of IPV. Education was positively related to both intrinsic and instrumental agency, but only instrumental agency was negatively associated with the likelihood of being a victim of IPV. Finally, both intrinsic and instrumental agencies were positively related to women's mental health. We discuss the importance of identifying specific factors related to women's power and agency to prevent IPV and mental health problems and to promote more gender equity in the Global South.

Are You All right (AYA)? Association of cumulative traumatic events among Danish police officers with mental health, work environment and sickness absenteeism: protocol of a 3-year prospective cohort study.

INTRODUCTION: Police officers are frequently exposed to potentially traumatic events at work that increases risk of developing mental health problems, in particular post-traumatic stress disorder (PTSD). Individual and organisational factors may influence the detrimental effects of cumulative exposure to traumatic events. Occupational stress and lack of organisational support are associated with increased risk of PTSD among police officers. The Are You All right? (AYA) project is a prospective cohort study investigating the cumulative effect of traumatic events at work on mental health problems and absenteeism among police officers. The study also investigates whether potential risk and protective factors modify the association of traumatic events at work with mental health problems and absenteeism. METHOD AND ANALYSIS: The AYA-study includes the entire Danish police force. Prospective survey data are collected over a 3-year period beginning in the spring of 2021. Electronic surveys are sent out at baseline with 1-year, 2-year and 3-year follow-up. Further, short surveys are sent out every third month, covering exposure to traumatic events and current mental health status. The survey data are paired with workplace register data on sickness absence. Register data on sickness absence cover the period from 2020 to 2025. ETHICS AND DISSEMINATION: This study was presented for evaluation at the National Ethics Committee in Denmark (reference number: 20202000-216), but according to Danish legislation, survey studies do not require approval by official Danish scientific or ethical committees. Participation in the project is based on informed consent, and data are handled in accordance with the Danish data legislation (journal number: 20/41457). Results are published in scientific journals and disseminated at international conferences.

Mapping the "catscape" formed by a population of pet cats with outdoor access.

The domestic cat (Felis catus) is among the most popular companion animals and most abundant carnivores globally. It is also a pet with an immense ecological footprint because even non-feral and food-subsidized cats can be prolific predators. Whereas knowledge about the spatial behavior of individual domestic cats is growing, we still know little about how a local population of free-ranging pet cats occupies the landscape. Using a citizen science approach, we GPS-tagged 92 pet cats with outdoor access living in a residential area in southern Norway. The resulting position data allowed us to construct both individual home range kernels and a population-level utilization distribution. Our results reveal a dense predatory blanket that outdoor cats drape over and beyond the urban landscape. It is this population-level intensity surface-the "catscape"-that potential prey have to navigate. There were few gaps in the catscape within our residential study area and therefore few terrestrial refuges from potential cat predation. However, cats spent on average 79% of their outdoor time within 50 m to their owner's home, which suggests that the primary impact is local and most acute for wildlife in the vicinity to homes with cats. We discuss the catscape as a conceptual and quantitative tool for better understanding and mitigating the environmental impact of domestic cats.

Lanthanum Carbonate Opacities-A Systematic Review.

BACKGROUND: Lanthanum carbonate is a phosphate binder used in advanced kidney disease. Its radiopaque appearance has been described in many case studies and case series. Misinterpretation of this phenomenon leads to unnecessary diagnostic tests and procedures. The objectives of this study were to summarize the literature on lanthanum carbonate opacities and present a visual overview. METHODS: A systematic search was conducted using MEDLINE, Embase, and Web of Science. We included all types of studies, including case reports/studies, describing radiological findings of lanthanum carbonate opacities in patients with chronic kidney disease. No filter for time was set. RESULTS: A total of 36 articles were eligible for data extraction, and 33 articles were included in the narrative synthesis. Lanthanum carbonate opacities were most commonly reported in the intestines (26 studies, 73%), stomach (8 studies, 21%), and the aerodigestive tract (2 studies, 6%). The opacities in the intestine were most frequently described as multiple, scattered radiopaque densities, compared with the aerodigestive tract, where the opacities were described as a single, round foreign body. Suspicion of contrast medium or foreign bodies was the most common differential diagnosis. LC opacities in patients with CKD are commonly misinterpreted as foreign bodies or suspect contrast media. CONCLUSIONS: CKD patients treated with LC may have opacities throughout the digestive tract that can vary in appearance. Stopping LC treatment or changing to an alternative phosphate binder prior to planned image studies can avoid diagnostic confusion. If this is not an option, knowledge of the presentation of LC opacities is important.

What Characterizes Vulnerability? Interdisciplinary Perspectives on Service Provision for Survivors of Sexual Assault.

Although research indicates that specialized sexual assault (SA) services are effective in terms of promoting postassault recovery and improving legal outcomes, little is known about how to best support survivors facing co-occurring difficulties and inequalities (e.g., preexisting mental health issues, substance abuse, poverty). This deficiency in knowledge was also expressed by service providers at Danish SA centers (SACs), who described this using the term "vulnerable survivors." Therefore, the present study aims to address this knowledge gap by exploring (a) how service providers understand vulnerability in the context of SA and (b) how service provision is currently approached for these survivors. Interviews were conducted with 18 service providers representing five professional groups (psychologists, social workers, forensic doctors, nurses, police) and analyzed using Interpretative Phenomenological Analysis. A total of eight themes emerged from the analysis, including service providers' descriptions of what characterizes vulnerability in survivors and broader perspectives on service provision for these survivors. Survivors considered least likely to attain desired supports were also those perceived to be most vulnerable with regards to risk and experiences surrounding sexual victimization (e.g., individuals with preexisting mental health issues). Service providers also believed that a large proportion of those served experience ongoing vulnerabilities that are difficult to manage within existing support models. The results thus suggest that survivors' needs cannot be met if vulnerabilities are overlooked or ignored. At the same time, the concept of vulnerability warrants caution since vulnerabilities are often placed within individual survivors, but the formal support system also appears vulnerable in its ability to meet the diverse needs and priorities of those served. The implications for SA services across the globe are discussed, including a need for more individually tailored and trauma-informed responses to SA that simultaneously address co-occurring difficulties and inequalities in survivors.

Physicians' experiences working in emergency medicine in a rural area in Northern Sweden: a qualitative study.

INTRODUCTION: Working in emergency medicine in rural areas may entail challenges due to absence of medical backup, difficulties in logistics, lack of healthcare system coordination, and, potentially, feelings of loneliness. The aim of this study was to elucidate the experiences of physicians working in an emergency medical setting in a rural area in Northern Sweden. METHODS: A qualitative study was performed based on semi-structured interviews. Six physicians were interviewed. The interviews were transcribed and analysed using the systematic text condensation method. RESULTS: Rural physicians described thriving in the rural environment. Four main themes were identified as important to their wellbeing and job satisfaction. They described close relations to the nearest referral centre, where they felt connected to the personnel in the centre. The participants described this as a crucial factor aiding their everyday work in emergency medicine. The rural physicians underlined educational and professional development individually, in teams training sessions, and through the locally created rural residency program for rural GPs as important. They expressed an adaptability to the rural environment and described having a problem-solving attitude. Additionally they found a functional transport system crucial as part of their workflow. CONCLUSION: Overall, the rural physicians thrived in the rural environment where interpersonal relations and creative initiatives along with a customised rural residency program prepared the physicians to work in rural areas. Despite the long distances between hospitals and health clinics, the physicians rarely felt alone in the field and the general well-functioning transport system with possibility for improvisations aided them in medical emergencies.

Magnesium transport in the aglomerular kidney of the Gulf toadfish (Opsanus beta).

Despite having an aglomerular kidney, Gulf toadfish can survive in water ranging from nearly fresh up to 70 parts per thousand salinity. In hyperosmotic environments, the major renal function is to balance the passive Mg2+ load from the environment with an equal excretion. However, the molecular transporters involved in Mg2+ secretion are poorly understood. We investigated whether environmental MgCl2 alone or in combination with elevated salinity affected transcriptional regulation of genes classically involved in renal Mg2+ secretion (slc41a1, slc41a3, cnnm3) together with three novel genes (trpm6, trpm7, claudin-19) and two isoforms of the Na+/K+-ATPase α-subunit (nka-α1a, nka-α1b). First, toadfish were acclimated to 5, 9, 35, or 60 ppt water (corresponding to ~ 7, 13, 50 and 108 mmol L-1 ambient [Mg2+], respectively) and sampled at 24 h or 9 days. Next, the impact of elevated ambient [Mg2+] was explored by exposing toadfish to control (50 mmol L-1 Mg2+), or elevated [Mg2+] (100 mmol L-1) at a constant salinity for 7 days. Mg2+ levels in this experiment corresponded with levels in control and hypersaline conditions in the first experiment. A salinity increase from 5 to 60 ppt stimulated the level of all investigated transcripts in the kidney. In Mg2+-exposed fish, we observed a 14-fold increase in the volume of intestinal fluids and elevated plasma osmolality and [Mg2+], suggesting osmoregulatory challenges. However, none of the renal gene targets changed expression compared with the control group. We conclude that transcriptional regulation of renal Mg2+ transporters is induced by elevated [Mg2+] in combination with salinity rather than elevated ambient [Mg2+] alone.

When cultures clash: Links between perceived cultural distance in values and attitudes towards migrants.

Migration elicits mixed reactions from the host-society. Negative responses towards migrants seem to emerge when migrants are perceived as culturally different. We investigated when and why perceived cultural distance (PCD) is associated with negative migrant attitudes by focussing on differences in cultural values. We expected that PCD in social values (focus on relationships and society) should be more strongly associated with attitudes towards migrants than personal values (individual needs and gains) and should be mediated by symbolic threat. In two quasi-experimental studies (N = 200, N = 668) with Dutch participants (host-society), we simultaneously tested effects of respondents' perception of Dutch values, their perceptions of migrant values (of Moroccan, Syrian, Polish ethnic origin), and PCD between Dutch-migrant value on attitudes. For all migrant groups, PCD in social values was associated with more negative attitudes, less tolerance, and less policy support regarding migrants; this was mediated by symbolic threat. These links were weaker for personal values.

Underserved survivors of sexual assault: a systematic scoping review.

Background: Despite knowledge about the extensive and often long-lasting consequences of sexual assault, many survivors remain underserved by formal support systems (e.g. medical, mental health and criminal justice systems). Reasons for underutilizing services are as diverse as the survivors themselves, and little is known about which survivors are most underserved and why they are underserved. Objective: To help organize existing findings on this topic, a systematic scoping review was conducted to identify adult survivors of sexual assault, who may be particularly underserved when attempting to obtain services in Western countries. Method: Five databases (PsycINFO, Embase, MEDLINE, Scopus and CINAHL) were systematically searched for studies published in English from 2000 onwards using terms such as 'sexual assault', 'help seeking', 'formal support', 'barriers' and variations thereof. Results: A total of 41 studies were included in the present scoping review, resulting in seven main categories of underserved survivors: Ethnic and cultural minorities, Disabilities, Financial vulnerability, Sexual and gender minorities, Mental health conditions, Problematic substance use, and Older age. Barriers encountered by survivors with these characteristics included limited access to formal supports and insufficient training and awareness among service providers about how to best support survivors. Conclusions: Recommendations include the need for more survivor-centred, culturally appropriate and trauma-informed services and more attention to survivors belonging to underserved groups in policy, practice and research.

Antecedentes: A pesar del conocimiento acerca de las consecuencias extensas y a menudo duraderas de la agresión sexual, muchos sobrevivientes permanecen desatendidos por los sistemas de apoyo formales (ej., sistemas médicos, salud mental y de justicia criminal). Las razones para la subutilización de los servicios son tan diversas como los propios sobrevivientes, y se conoce poco acerca de qué sobrevivientes son los más desatendidos y las razones de por qué lo son.Objetivo: Para ayudar a organizar los hallazgos existentes en este tema, se realizó una revisión sistemática del alcance para identificar, en países occidentales, a sobrevivientes adultos de agresión sexual, quienes pueden ser particularmente desatendidos cuando intentan obtener apoyo.Método: Se buscó sistemáticamente en cinco bases de datos (PsycINFO, Embase, MEDLINE, Scopus y CINHAL) estudios publicados en Inglés desde el 2000 en adelante, usando los términos 'agresión sexual', 'búsqueda de ayuda', 'apoyo formal', 'barreras' y variaciones de los mismos.Resultados: Se incluyó un total de 41 estudios en la presente revisión del alcance, resultando en siete categorías principales de sobrevivientes desatendidos: Minorías étnicas y culturales, Discapacidades, Vulnerabilidad económica, Minorías sexuales y de género, Condiciones de salud mental, Uso problemático de sustancias y mayor edad. Las barreras encontradas por los sobrevivientes con estas características fueron acceso limitado a los apoyos formales e insuficiente entrenamiento y conocimiento entre los proveedores de los servicios acerca de cuál es la mejor forma de apoyar a los sobrevivientes.Conclusiones: Las recomendaciones incluyen la necesidad de servicios más centrados en el sobreviviente, adecuados culturalmente e informados en trauma y mayor atención a los sobrevivientes que pertenecen a los grupos desatendidos en relación a las políticas, práctica clínica e investigación.

The role of GLP-1 in the postprandial effects of acarbose in type 2 diabetes.

AIMS: The alpha-glucosidase inhibitor acarbose is believed to reduce plasma glucose by delaying hydrolysis of carbohydrates. Acarbose-induced transfer of carbohydrates to the distal parts of the intestine increases circulating glucagon-like peptide 1 (GLP-1). Using the GLP-1 receptor antagonist exendin(9-39)NH2, we investigated the effect of acarbose-induced GLP-1 secretion on postprandial glucose metabolism in patients with type 2 diabetes. METHODS: In a double-blinded, placebo-controlled, randomized, crossover study, 15 participants with metformin-treated type 2 diabetes (age: 57-85 years, HbA1c: 40-74 mmol/mol) were subjected to two 14-day treatment periods with acarbose or placebo, respectively, separated by a 6-week wash-out period. At the end of each period, two randomized 4-h liquid mixed meal tests with concomitant infusion of exendin(9-39)NH2 and saline, respectively, were performed. RESULTS: Compared to placebo, acarbose increased postprandial GLP-1 concentrations and decreased postprandial glucose. We observed no absolute difference in the exendin(9-39)NH2-induced increase in postprandial glucose excursions between placebo and acarbose periods, but relatively, postprandial glucose was increased by 119 ± 116% (mean ± s.d.) during exendin(9-39)NH2 infusion in the acarbose period vs a 39 ± 27% increase during the placebo period (P = 0.0163). CONCLUSIONS: We confirm that acarbose treatment stimulates postprandial GLP-1 secretion in patients with type 2 diabetes. Using exendin(9-39)NH2, we did not see an impact of acarbose-induced GLP-1 secretion on absolute measures of postprandial glucose tolerance, but relatively, the effect of exendin(9-39)NH2 was most pronounced during acarbose treatment.

Intimate Partner Violence and Electronic Health Interventions: Systematic Review and Meta-Analysis of Randomized Trials.

BACKGROUND: Intimate partner violence (IPV) is a major public health concern. eHealth interventions may reduce exposure to violence and health-related consequences as the technology provides a safe and flexible space for the target population. However, the evidence is unclear. OBJECTIVE: The goal of the review is to examine the effect of eHealth interventions compared with standard care on reducing IPV, depression, and posttraumatic stress disorder (PTSD) among women exposed to IPV. METHODS: We searched EMBASE, MEDLINE, Cochrane Central Register of Controlled Trials, PsycInfo, Scopus, Global Health Library, ClinicalTrials.gov, and International Clinical Trials Registry Platform for published and unpublished trials from inception until April 2019. Trials with an eHealth intervention targeting women exposed to violence were included. We assessed risk of bias using the Cochrane Risk of Bias Tool. Trials that reported effect estimates on overall IPV; physical, sexual, and psychological violence; depression; or posttraumatic stress disorder were included in meta-analyses. RESULTS: A total of 14 trials were included in the review; 8 published trials, 3 unpublished trials and 3 ongoing trials. Of the 8 published trials, 2 were judged as overall low risk of bias trials. The trials reported 23 types of outcomes, and 7 of the trials had outcomes that were eligible for meta-analyses. Our pooled analyses found no effect of eHealth interventions on any of our prespecified outcomes: overall IPV (SMD -0.01; 95% CI -0.11 to 0.08; I2=0%; 5 trials, 1668 women); physical violence (SMD 0.01; 95% CI -0.22 to 0.24; I2=58%; 4 trials, 1128 women); psychological violence (SMD 0.07; 95% CI -0.12 to 0.25; I2=40%; 4 trials, 1129 women); sexual violence (MD 0.36; 95% CI -0.18 to 0.91; I2=0%; 2 trials, 1029 women); depression (SMD -0.13; 95% CI -0.37 to 0.11; I2=78%; 5 trials, 1600 women); and PTSD (MD -0.11; 95% CI -1.04 to 0.82; I2=0%; 5 trials, 1267 women). CONCLUSIONS: There is no evidence from randomized trials of a beneficial effect of eHealth interventions on IPV. More high-quality trials are needed, and we recommend harmonizing outcome reporting in IPV trials by establishing core outcome sets.

GIP and GLP-1 Potentiate Sulfonylurea-Induced Insulin Secretion in Hepatocyte Nuclear Factor 1α Mutation Carriers.

Sulfonylureas (SUs) provide an efficacious first-line treatment in patients with hepatocyte nuclear factor 1α (HNF1A) diabetes, but SUs have limitations due to risk of hypoglycemia. Treatment based on the incretin hormones glucose-dependent insulinotropic peptide (GIP) and glucagon-like peptide 1 (GLP-1) is characterized by their glucose-dependent insulinotropic actions without risk of hypoglycemia. The effect of SUs together with GIP or GLP-1, respectively, on insulin and glucagon secretion in patients with HNF1A diabetes is currently unknown. To investigate this, 10 HNF1A mutation carriers and 10 control subjects without diabetes were recruited for a double-blinded, placebo-controlled, crossover study including 6 experimental days in a randomized order involving 2-h euglycemic-hyperglycemic clamps with coadministration of: 1) SU (glimepiride 1 mg) or placebo, combined with 2) infusions of GIP (1.5 pmol/kg/min), GLP-1 (0.5 pmol/kg/min), or saline (NaCl). In HNF1A mutation carriers, we observed: 1) hypoinsulinemia, 2) insulinotropic effects of both GIP and GLP-1, 3) additive to supra-additive effects on insulin secretion when combining SU+GIP and SU+GLP-1, respectively, and 4) increased fasting and arginine-induced glucagon levels compared with control subjects without diabetes. Our study suggests that a combination of SU and incretin-based treatment may be efficacious in patients with HNF1A diabetes via potentiation of glucose-stimulated insulin secretion.
