Abstract
BACKGROUND Particularly in rural regions, factors such as lower physician density and long travel distances complicate adequate outpatient care. However, urban regions can also be affected by deficits in care, for example, long waiting times. One model of care intending to improve the situation is the implementation of video consultations. The study protocol presents the methodology of the research project titled "Preference-based implementation of the video consultation in urban and rural regions" funded by the German Federal Joint Committee (funding number 01VSF20011). OBJECTIVE This study aims to identify existing barriers to the use of video consultation and the preferences of insured individuals and physicians as well as psychotherapists in order to optimize its design and thus increase acceptance and use of video consultations in urban and rural regions. METHODS Built on a mixed methods approach, this study first assesses the status quo of video consultation use through claims data analysis and carries out a systematic literature review on barriers and promoting factors for the use of video consultations. Based on this preliminary work, focus groups are conducted in order to prepare surveys with insureds as well as physicians and psychotherapists in the second study phase. The central element of the survey is the implementation of discrete choice experiments to elicit relevant preferences of (potential) user groups and service providers. The summarized findings are discussed in a stakeholder workshop and translated into health policy recommendations. RESULTS The methodological approach used in this study is the focus of this paper. The study is still ongoing and will continue until March 2024. The first study phase has already been completed, in which preliminary work has been done on potential applications and hurdles for the use of video consultations. Currently, the survey is being conducted and analyses are being prepared. CONCLUSIONS This study is intended to develop a targeted strategy for health policy makers based on actual preferences and perceived obstacles to the use of video consultations. The results of this study will contribute to further user-oriented development of the implementation of video consultations in German statutory health insurance. Furthermore, the iterative and mixed methods approach used in this study protocol is also suitable for a variety of other research projects.

Abstract
BACKGROUND In settings like the ambulatory care sector in Germany, where data on the outcomes of interdisciplinary health services provided by multiple office-based physicians are not always readily available, our study aims to develop a set of indicators of health care quality and utilization for 14 groups of ambulatory-care-sensitive conditions based on routine data. These may improve the provision of health care by informing discussions in quality circles and other meetings of networks of physicians who share the same patients. METHODS Our set of indicators was developed as part of the larger Accountable Care in Deutschland (ACD) project using a pragmatic consensus approach. The six stages of the approach drew upon a review of the literature; the expertise of physicians, health services researchers, and representatives of physician associations and statutory health insurers; and the results of a pilot study with six informal network meetings of office-based physicians who share the same patients. RESULTS The process resulted in a set of 248 general and disease specific indicators for 14 disease groups. The set provides information on the quality of care provided and on patient pathways, covering patient characteristics, physician visits, ambulatory care processes, pharmaceutical prescriptions and outcome indicators. The disease groups with the most indicators were ischemic heart diseases, diabetes and heart failure. CONCLUSION Our set of indicators provides useful information on patients' health care use, health care processes and health outcomes for 14 commonly treated groups of ambulatory-care-sensitive conditions. This information can inform discussions in interdisciplinary quality circles in the ambulatory sector and foster patient-centered care.

Abstract
Background Patients in Germany are free to seek care from any office-based physician and can always ask for multiple opinions on a diagnosis or treatment. The high density of physicians and the freedom to choose among them without referrals have led to a need for better coordination between the multiple health professionals treating any given patient. The objectives of this study are to (1) identify informal networks of physicians who treat the same patient population, (2) provide these physicians with feedback on their network and patients, using routine data and (3) give the physicians the opportunity to meet one another in facilitated network meetings. Methods The Accountable Care Deutschland (ACD) study is a prospective, non-blinded, cluster-randomised trial comprising a process and economic evaluation of informal networks among 12,525 GPs and office-based specialists and their 1.9 million patients. The units of allocation are the informal networks, which will be randomised either to the intervention (feedback and facilitated meetings) or control group (usual care). The informal networks will be generated by identifying connections between office-based physicians using complete datasets from the Regional Associations of Statutory Health Insurance (SHI) Physicians in Hamburg, Schleswig Holstein, North Rhine and Westphalia Lip, as well as data from three large statutory health insurers in Germany. The physicians will (a) receive feedback on selected indicators of their own treatment activity and that of the colleagues in their network and (b) will be invited to voluntary, facilitated network meetings by their Regional Association of SHI physicians. The primary outcome will be ambulatory-care-sensitive hospitalisations at baseline, at the end of the 2-year intervention period, and at six months and at 12 months after the end of the intervention period. Data will be analysed using the intention-to-treat principle. A pilot study preceded the ACD study. Discussion Cochrane reviews show that feedback can improve everyday medical practice by shedding light on previously unknown relationships. Providing physicians with information on how they are connected with their colleagues and what the outcomes are of care delivered within their informal networks can help them make these improvements, as well as strengthen their awareness of possible discontinuities in the care they provide.

Abstract
INTRODUCTION New challenges arise in medicine, particularly in psychiatry. In the near future, psychiatrists' role may evolve into management of mental health care teams (GPs, nurses, psychologists…) thus creating the need for charisma and leadership. Charisma is defined as « a quality that allows it's possessor to exercise influence, authority over a group »; leadership as « the function, the position of chief, and by extension, a dominant position ». AIM OF THE STUDY To offer some reflections on charisma and leadership and the ways to develop them in three situations common in clinical practice: dual communication (between caregivers or with patients), oral communication (e.g., during a symposium) and managing a mental health care team. METHOD Medline (1966-hits) and Web of Science (1975-hits) were explored according to the PRISMA criteria. The research paradigm was [(psychiatrist OR physician) AND mental health AND (leadership OR charisma)]. RESULTS Two hundred and eighty articles were found, but only 34 corresponded to our subject and were included in the qualitative analysis. The leader must first ask himself/herself about his/her vision of the future, so as to share it with passion with his/her mental health team. Charisma and leadership are based on several values, among which we can mention: providing understandable, personalized care for the patient, in continuity and confidentiality; adapting care to the general population's request, maintaining one's own physical and mental health, submitting one's daily practice to peer review, engaging in continuous improvement of one's practices in response to new requirements, and recognizing that research and instruction are part of an M.D's professional obligations. The clinician will work on ways to develop his/her own charisma, through interactions with peers and team members, the care of his/her appearance (especially for first meetings) and workplace, and through positive reinforcement (some cognitive-behavioral techniques like assertiveness have been proposed to enhance the charisma, e.g., visualization and affirmation). Leadership does not depend on hierarchical position and administrative responsibilities: leaders should learn to manage and harmonize the different types of personalities within his/her team, paying special attention to passive-aggressive attitudes. We recall here some techniques to improve charisma during oral communication, such as making relationships with people by calling them by their names, making reference to things and people that the audience can identify with (like sport or cooking), using one's own style without trying to imitate someone else, focusing on one major idea, being brief and using anecdotes, using silences effectively and finally having good non-verbal communication. The conclusion should never be neglected, as an audience especially remembers the beginning and the end of a presentation. Although some features are common to all charismatic leaders (dominance, self-confidence, high energy level), a recent theory of leadership (called contingency theory) seeks to examine how different leadership styles can adapt to circumstances. This theory focuses more on the vision, passion, determination and courage of the leader and depends not only on their intrinsic qualities. No research has indeed shown individual characteristics that differentiate leaders from followers. However, doctors have not been prepared in their training to acquire leadership skills that they can use to adapt to the circumstances of their clinical practice. The most important qualities expected of a leader according to the current leadership theorists are: listening, communication, stress management, development of other's capacities, feedback, introspection and risk taking. Moreover, leadership involves positive reinforcement of the team while maintaining the feeling of individual autonomy, and being able to take an innovative decision alone with shared optimism. There is no need to have great management responsibilities in order to succeed in leadership. We reiterate the importance for a charismatic leader to smile, to be able to mock oneself and to regulate one's emotions. CONCLUSION Charisma seems to be an essential dimension for effective leadership and team management. Beyond psychiatry, we believe these reflections to be useful for all branches of medicine.

Abstract
INTRODUCTION Seventy-five percent of patients with blood-injection-injury phobia (BII-phobia) report a history of fainting in response to phobic stimuli. This specificity may lead to medical conditions remaining undiagnosed and untreated, incurring considerable cost for the individual and society. The psychophysiology of BII-phobia remains poorly understood and the literature on effective treatments has been fairly sparse. Aims of the systematic review: to synthesize the psychophysiology of BII-phobia and to propose a systematic review of the literature on effectiveness of different treatments evaluated in this indication. RESULTS Firstly, the most distinct feature of the psychophysiology of BII-phobia is its culmination in a vasovagal syncope, which has been described as biphasic. The initial phase involves a sympathetic activation as is typically expected from fear responses of the fight-flight type. The second phase is characterized by a parasympathetic activation leading to fainting, which is associated with disgust. Subjects with syncope related to BII-phobia have an underlying autonomic dysregulation predisposing them to neurally mediated syncope, even in the absence of any blood or injury stimulus. Many studies report that BII-phobic individuals have a higher level of disgust sensitivity than individuals without any phobia. Secondly, behavioral psychotherapy techniques such as exposure only, applied relaxation, applied tension, and tension only, have demonstrated efficacy with no significant difference between all these techniques. The disgust induction has not improved effectiveness of exposure. CONCLUSION We have explained the psychophysiology of BII-phobia, the understanding of which is required to study and validate specific techniques, in order to improve the prognosis of this disorder, which is a public health issue.

Abstract
INTRODUCTION Toxoplasma gondii is the most common protozoan parasite in developed nations. Up to 43% of the French population may be infected, depending on eating habits and exposure to cats, and almost one third of the world human's population may be infected. Two types of infection have been described: a congenital form and an acquired form. Although the medical profession treats these latent cases as asymptomatic and clinically unimportant, results of animal studies and recent studies of personality profiles, behavior, and psychomotor performance have led to reconsider this assumption. PRECLINICAL DATA Among rats: parasite cysts are more abundant in amygdalar structures than those found in other regions of the brain. Infection does not influence locomotion, anxiety, hippocampal-dependent learning, fear conditioning (or its extinction) and neophobia in rats. Rats' natural predator is the cat, which is also T. gondii's reservoir. Naturally, rats have an aversion to cat urine, but the parasite suppresses this aversion in rats, thus influencing the infection cycle. Tachyzoites may invade different types of nervous cells, such as neurons, astrocytes and microglial cells in the brain, and Purkinje cells in cerebellum. Intracellular tachyzoites manipulate several signs for transduction mechanisms involved in apoptosis, antimicrobial effectors functions, and immune cell maturation. Dopamine levels are 14% higher in mice with chronic infections. These neurochemical changes may be factors contributing to mental and motor abnormalities that accompany or follow toxoplasmosis in rodents and possibly in humans. Moreover, the antipsychotic haloperidol and the mood stabilizer valproic acid most effectively inhibit Toxoplasma growth in vitro with synergistic activity. CLINICAL DATA The effects of the parasite are not due to the manipulation in an evolutionary sense but merely due to neuropathological or neuroimmunological effects of the parasite's presence. Toxoplasmosis and schizophrenia: epidemiological studies point to a role for toxoplasmosis in schizophrenia's etiology, probably during pregnancy and early life, this association being congruent with studies in animal models indicating that animal exposures of the developing brain to infectious agents or immune modulating agents can be associated with behavioral changes that do not appear until the animal reaches full maturity. Psychiatric patients have increased rates of toxoplasmic antibodies, the differences between cases and controls being greatest in individuals who are assayed near the time of the onset of their symptoms. The increase of dopamine in the brain of infected subjects can represent the missing link between toxoplasmosis and schizophrenia. Toxoplasmosis and Obsessive Compulsive Disorder (OCD): the seropositivity rate for anti-T. gondii IgG antibodies among OCD patients is found to be significantly higher than the rate in healthy volunteers. Infection of basal ganglia may be implicated in the pathogenesis of OCD among Toxoplasma seropositive subjects. Toxoplasmosis and personality: infected men appear to be more dogmatic, less confident, more jealous, more cautious, less impulsive and more orderly than others. Conversely, infected women seem warmest, more conscientious, more insecure, more sanctimonious and more persistent than others. It is possible that differences in the level of testosterone may be responsible for the observed behavioral differences between Toxoplasma-infected and Toxoplasma-free subjects. CONCLUSION In the future two major avenues for research seem essential. On one hand, prospective studies and research efforts must still be carried out to understand the mechanisms by which the parasite induces these psychiatric disorders. On the other hand, it has not yet been demonstrated that patients with positive toxoplasmic serology may better respond to haloperidol's or valproic acid's antiparasitic activity. These results may appear as a major issue in the drug's prescribing choices and explain variability in response to the treatment of patients with schizophrenia that is not explained by the genetic polymorphism.

Abstract
INTRODUCTION Important data was recently published on the potential genotoxic or carcinogenic effects of antipsychotics, as well as on their cytotoxic properties on cancer cells, that must be considered by psychiatrists in the benefit/risk ratio of their prescriptions. AIM OF THE STUDY To answer whether or not antipsychotics, as a class or only some specific molecules, may influence cancer risk among treated patients. METHODS ELIGIBILITY CRITERIA: All studies (in vitro, animal studies and human studies) concerning effects of antipsychotic drugs on cancer development were included. The search paradigm [neoplasms AND (antipsychotic agents OR neuroleptic OR phenothiazine)] was applied to Medline (1966-present) and Web of Science (1975-present). RESULTS Ninety-three studies were included in the qualitative synthesis. Results can be summarized as follows: (1) patients with schizophrenia may be less likely to develop cancer than the general population, (2) antipsychotics as a class cannot be considered at the moment as at risk for cancer, even if some antipsychotics have shown carcinogenic properties among rodents, (3) phenothiazines seem to have antiproliferative properties that may be useful in multidrug augmentation strategies in various cancer treatments, but their bad tolerance may decrease usage amongst non-psychotic patients, and (4) clozapine appears to have a separate status given that this molecule shows antiproliferative effects implied in agranulocytosis as well as a potential increased risk for leukemia. CONCLUSION Benefit/risk ratio regarding cancer risk is in favor of treating patients with schizophrenia with antipsychotic drugs. The practicing clinician should be reassuring on the subject of cancer risk due to antipsychotic drugs.
