In Switzerland, altruistic assisted suicide is permitted. We present here the federal regulations, the deontological rules, the provisions adopted by the cantons and other requirements applicable to assisted suicide. Given the complexity of these different rules and the legal questions that remain open, we recommend the preparation of brochures for patients, as well as better training and support for people faced with requests for assisted suicide.

International audience; Background The identification of patients at high risk of a disabling disease course would be invaluable in guiding initial therapy in Crohn’s disease (CD). Our objective was to evaluate a combination of clinical, serological, and genetic factors to predict complicated disease course in pediatric-onset CD. Methods Data for pediatric-onset CD patients, diagnosed before 17 years of age between 1988 and 2004 and followed more than 5 years, were extracted from the population-based EPIMAD registry. The main outcome was defined by the occurrence of complicated behavior (stricturing or penetrating) and/or intestinal resection within the 5 years following diagnosis. Lasso logistic regression models were used to build a predictive model based on clinical data at diagnosis, serological data (ASCA, pANCA, anti-OmpC, anti-Cbir1, anti-Fla2, anti-Flax), and 369 candidate single nucleotide polymorphisms. Results In total, 156 children with an inflammatory (B1) disease at diagnosis were included. Among them, 35% (n = 54) progressed to a complicated behavior or an intestinal resection within the 5 years following diagnosis. The best predictive model (PREDICT-EPIMAD) included the location at diagnosis, pANCA, and 6 single nucleotide polymorphisms. This model showed good discrimination and good calibration, with an area under the curve of 0.80 after correction for optimism bias (sensitivity, 79%, specificity, 74%, positive predictive value, 61%, negative predictive value, 87%). Decision curve analysis confirmed the clinical utility of the model. Conclusions A combination of clinical, serotypic, and genotypic variables can predict disease progression in this population-based pediatric-onset CD cohort. Independent validation is needed before it can be used in clinical practice.

Health services and systems research examines the match between individual and population health needs and clinical services. In the context of the ambulatory shift in psychiatry, services research is important to ensure the quality of clinical developments, their appropriateness to patient and societal needs, their accessibility, efficiency, implementation and real-world outcomes. The purpose of this article is to present the principles that guide mental health services and systems research and to illustrate them with three examples related to the ambulatory shift in psychiatry. Research on services must be based on both epidemiological and clinical research as well as on partnerships with expert patients.

In June 2021, the Swiss parliament accepted a legislative proposal calling for the introduction of a fee to fight emergency department (ED) overcrowding. Although this issue remains a major challenge for health policies, the introduction of such a fee raises many questions, notably regarding health equity. However, other more equitable solutions exist: improving the case management of ED frequent users and improving coordination between ED and primary care.

Training provided by liaison psychiatry has been considerably developed over the last decades. This article describes how " communication skills" training in oncology evolved to now address interpersonal dimensions of the medical encounter, the clinician's "inner" world and the context. We further present a so-called clinician-centered supervision, which aims to address the intra psychic issues of the clinician; the opportunities and precautions with this specific type of supervision are discussed. Focusing on the clinician facilitates and enriches the clinical encounter and improves medical care.

Adolescents aged 10 to 19 live a period of their life marked by opportunities and vulnerabilities during which the issue of mental health is of prime importance. Since several decades, and especially since the start of the COVID pandemic, mental health problems and disorders among adolescents have increased around the world. Depression, self-harm and suicidal behavior are common during this period of life, and pediatricians can play a pivotal role in identifying affected or vulnerable youngsters. This article describes risk factors for self-harm and suicidal behavior and reviews how primary care pediatricians and health professionals can respond to such situations. This scoping review is based on existing evidences as well as the authors clinical experience. It suggests concrete actions that can be taken to secure the life of at risk teenagers, and discusses how to organize the transfer to mental health professionals when needed.

Men die more by suicide than women, but women attempt suicide more frequently. Gender does indeed shape suicidal ideas and behaviors. Due to differences in the way men express their suffering, men's depression may be underdiagnosed and undertreated. Furthermore, regarding suicidal behaviors, men use more lethal suicide methods than women. Their suicidal process seems also to progress more rapidly, which is probably related to their frequent substance use. Clinicians and researchers should consider these differences in their approach, without reducing men and women to their gender.

The context of the clinical encounter, and more generally of the practice of medicine, has effects on physicians. For example, it shapes their opinions, discourses, and ultimately their behaviors. The context may also directly impact physicians, sometimes affecting their physical and mental health. Numerous interventions, provided within and outside the institution, are targeting these effects. The question we raise in this article is: should physicians adapt to, or should they rather situate themselves within, their context. This question leads us to discuss reflexivity and reflexivity training.

Patients and their clinical predicaments have an impact on clinicians (that psychoanalysis frames as countertransference), but also on medical institutions. Suicidal patients provide a potent illustration of such phenomena. At the individual level, they evoke intense, often negative affective reactions. At the institutional level, they are also « difficult » patients, who often do not conform to the classical, « expected » sick role. This can result in policies too focused on risk assessment and strict procedures, potentially detrimental to proper care. To prevent such defensive attitudes, institutions should provide clinicians an environment in which they are able to work through their relationships with patients, but also with the medical profession and institutions.

In Switzerland and elsewhere, many psychological support hotlines were set up during the acute phase of the COVID-19 pandemic. Specialists in psychological first aid, in charge of developing and managing these hotlines, had to face an unknown situation, very different from the disasters for which they prepare themselves. Since the pandemic and the associated physical distancing were a potential threat to social cohesion, one could make the hypothesis that, by setting up hotlines, these professionals sought to reintroduce a form of proximity and to care for and cultivate the social connections among people. The pressure, feelings of emergency, anxious anticipation and expectation of the political authorities and the population may have favoured the development of these structures. Other factors certainly also played a role, such as the need to be useful and to exist as professional, or the need to act in order to reduce anxiety related to the pandemic. Altogether, these hotlines were little used, and their usefulness may be questioned. Similar phenomena have been observed - especially in the sanitary domain - with a multiplication of new offers, not always adjusted to specific identified needs, while health care services were on the same time under-used. Our observations plead against emergency responses in crisis situations and for reflecting on the measures to be put in place rather than to "act" them.

In the field of suicide prevention, the identification of risk groups is important, as is the training of front-line workers, to raise awareness of suicide issues. Agricultural workers represent a group at high risk of suicidal behavior due to various factors (low income of farmers, work related to climatic conditions, social isolation, poor access to primary care). The main objective of this article is to present the implementation of prevention training in suicide prevention for a population of agricultural workers in two cantons of French-speaking Switzerland (Vaud and Neuchâtel) which represent a population of about 980,000 inhabitants. The second objective is to identify the experiences of the participants in this training and their expectations. Suicide prevention training sessions are organized in collaboration with public health departments, agriculture departments and suicide prevention professionals. Each session is led by four trainers experienced in suicide prevention and belonging to the "Groupement Romand Prévention du Suicide" (GRPS) which manages the training and other training modules on this topic in French-speaking Switzerland. The GRPS guarantees the content of the training as well as the updating of scientific knowledge. The training model is based on a concept that alternates between brief theoretical contributions, exchanges between participants in plenary sessions and role playing in small groups. The training has two main objectives: on the one hand to work on the participants' representations of suicide and to modify their posture by training "sentinels", i.e. "peers" who can establish a link between suffering individuals and the available support resources. On the other hand, to give key messages: dare to talk about the suicidal question and to not remain alone with this. Between December 2016 and May 2018, nine sessions were held in the two cantons of Vaud and Neuchâtel with a total of 220 participants. The sessions took place in agricultural schools or buildings related to agriculture. Invited to express themselves on the theme of suicide as well as on the concept of training, agricultural workers all verbalized the importance of this issue and were often very moved when the subject was discussed. The topics addressed by the participants were the taboo aspect of the subject, the difficulty of talking about it and the need to be able to address the subject (breaking the isolation). Participants also highlighted the need for peers to act as relays for help. The sessions were highly appreciated by the organizers concerned, particularly by the public health and agricultural departments. Participants expressed their satisfaction at the opportunity to express their views on this subject, regretting that such initiatives are all too rare. Although studies highlight the difficulty of emotional expression in the agricultural field, we observed on the contrary a great facility of the participants to express their emotions in relation to the suicidal theme. We have highlighted that the issue of suicide in this population is linked to several causal factors, as is the suicidal issue more broadly. Factors specific to this population emerged from the sessions, including working conditions and difficulties related to the family environment of farmers. There is a need to strengthen suicide prevention with training programs among the agricultural population. We also note the major importance of improving access to mental health care which is often very deficient in rural areas.

Coronavirus pandemic challenges mental health care providers in different ways. At an individual level, they have to adapt their clinical practice and consider specific issues of teleconsultations to address patient's needs. At a population level, dedicated interventions (e.g. hotlines, health professionals' support) have to strike a balance between « pathologizing » people's reactions and trivializing the psychological effects of a pandemic. Finally, psychiatric leaders must be able to advise decision-makers on mental-health policy and communication.

International audience; Parents of a child with a congenital malformation including esophageal atresia (OA), congenital diaphragmatic hernia (CDH), or intestinal atresia (IA) have to face various potentially stressful situations and exercise their role in a highly medicalized context. Yet no study has so far sought to identify the factors that facilitate or make difficult their adjustment of the first months.This study aimed to propose a grounded theory to account for the dynamics of parental adjustment for the period from the announcement of the diagnosis to the age of one year of the child with a rare abdominothoracic malformation requiring neonatal surgery. Participants were recruited to form a reasoned sample of 30 parents of children aged from 12 to 36 months with an OA, a CDH, or an IA. To date, 22 parents (17 mothers and 5 fathers) have been included. Semistructured individual interviews were conducted in which four main themes were discussed: the medical and hospital care of the child, the daily life with the child at home, the consequences of the illness on family life, and personal experience.Preliminary results show that the child's condition impact parental adjustment and family functioning. Parents reported high level of distress and fatigue during the first year of their child. The highly medicalized context makes it more difficult for parents to practice their parental role and bring them to expense energy to implement normalization strategies in their parental practices.Interestingly, the relationship with doctors and medical staff has been widely discussed by parents. Most of them felt a lack of information about their child's condition, or felt that the information was not authentic. Some of them felt that doctors were trying to protect them by omitting certain events that they ended up learning by the medical staff. All parents pointed the availability, the quality of the educational relationship, the emotional and informational support from the medical staff allowing them to feel more effective and to reduce their negative feelings.Results of our study will be used to design appropriate psychoeducational interventions in order to improve support for families.

Heavy metals (HMs) and polychlorobiphenyls (PCBs) enter the Arctic environment through a variety of anthropogenic sources with deleterious effects towards biota and public health. Bacteria first transfer toxic compounds to higher trophic levels and, due to the tight link existing between prokaryotic community functions and the type and concentration of contaminants, they may be useful indicator of pollution events and potential toxicity to other forms of life. The occurrence and abundance of HM-tolerant and PCB-oxidizing bacteria in the sub-Arctic Pasvik river area, heavily impacted by anthropogenic modifications, was related to HM and PCB contamination. This latter more likely derived from local inputs rather than a global contamination with higher PCB and HM amounts (and higher bacterial viable counts) that were determined in inner and middle sections of the River. Finally, a panel of bacteria with potential applications in the bioremediation of cold environments were selected and phylogenetically identified.

Marinobacter sp. W1-16 from Antarctic surface seawater was analysed for the production of extracellular polymeric substances (EPSs). Enhancement of the EPS biosynthesis was carried out by evaluating the influences of the carbon source (type and concentration), temperature, pH and salinity. EPS yields varied strongly depending on sugar substrate and temperature, while pH and salinity did not strongly affect levels of EPS production. Marinobacter sp. W1-16 produced the highest quantity of EPSs when growing at 15°C and pH 8, in the presence of 2% glucose and 3% NaCl. The EPS chemical characterization revealed a molecular weight of about 260 kDa. Colorimetric assays determined a higher quantity of carbohydrate than of proteins and uronic acids, as well as the presence of sulphate, in the extracted EPSs. The monosaccharidic composition resulted in Glc:Man: Gal:GalN:GalA:GlcA in relative molar proportions of 1:0.9:0.2:0.1:0.1:0.01. Some biotechnological potentialities (i.e. emulsifying and cryoprotective actions, and heavy metal binding properties) of the EPSs were proved, suggesting possible industrial and bioremediation applications.
