[How I treat…the cardiogenic acute pulmonary oedema].

In the context of Acute Pulmonary Edema (APE), the old school moto was LMNOP, for "Lasix-Morphine-Nitrates-Oxygen-Positive Pressure". However, this mnemonic, while not entirely inaccurate, deserves revision or at least a slight reinterpretation. APE remains a well-known condition in emergency departments, with a high mortality rate.

Nucleus accumbens D1- and D2-expressing neurons control the balance between feeding and activity-mediated energy expenditure.

Accumulating evidence points to dysregulations of the Nucleus Accumbens (NAc) in eating disorders (ED), however its precise contribution to ED symptomatic dimensions remains unclear. Using chemogenetic manipulations in male mice, we found that activity of dopamine D1 receptor-expressing neurons of the NAc core subregion facilitated effort for a food reward as well as voluntary exercise, but decreased food intake, while D2-expressing neurons have opposite effects. These effects are congruent with D2-neurons being more active than D1-neurons during feeding while it is the opposite during running.

Impact of membrane lipid polyunsaturation on dopamine D2 receptor ligand binding and signaling.

Increasing evidence supports a relationship between lipid metabolism and mental health. In particular, the biostatus of polyunsaturated fatty acids (PUFAs) correlates with some symptoms of psychiatric disorders, as well as the efficacy of pharmacological treatments. Recent findings highlight a direct association between brain PUFA levels and dopamine transmission, a major neuromodulatory system implicated in the etiology of psychiatric symptoms.

Hop Extract Anti-Inflammatory Effect on Human Chondrocytes Is Potentiated When Encapsulated in Rapeseed Lecithin Nanoliposomes.

Hop ( L.) is a plant used as an ingredient in beer or employed for its anti-inflammatory properties. The cultivation of hops is currently dedicated to the brewing industry, where mainly female flowers are used, whereas aerial parts, such as leaves, are considered coproducts.

[Psychological impact of involvement of medical and psychological emergency unit professionals in the medical and psychological care system of the COVID-19 epidemic].

Objectives: COVID-19 pandemic and its consequences have put into great difficulty health professionals, and the general population, fostering the emergence of various psychological and psychiatric disorders. Medical and psychological emergency units' mission is the medical and psychological emergency care of people impacted during a traumatic event. Given their expertise in crisis management, they set up an important medical and psychological support system adapted to the health crisis' characteristics.

Prevention and control of highly antibiotic-resistant bacteria in a Pacific territory: Feedback from New Caledonia between 2004 and 2020.

Objective: Carbapenemase-producing Enterobacteriaceae (CRE) and Enterococcus faecium resistant to vancomycin (VRE) constitute major threats to public health worldwide. The Pacific area is concerned and has implemented strategies to control antimicrobial resistance (AMR). However, accurate epidemiological data are rarely reported.

Microarray and Mass Spectrometry-Based Methodology for Lipid Profiling of Tissues and Cell Cultures.

The recent developments in mass spectrometry have revealed the importance of lipids as biomarkers in the context of different diseases and as indicators of the cell's homeostasis. However, further advances are required to unveil the complex relationships between lipid classes and lipid species with proteins. Here, we present a new methodology that combines microarrays with mass spectrometry to obtain the lipid fingerprint of samples of a different nature in a standardized and fast way, with minimal sample consumption.

Tetrahydrobiopterin administration facilitates amphetamine-induced dopamine release and motivation in mice.

Dopamine (DA) is a critical neurotransmitter involved in motivational processes. Tetrahydrobiopterin (BH4) is an essential cofactor for tyrosine hydroxylase, the rate-limiting enzyme in DA synthesis. Decreases in BH4 levels are observed in several DA-related neuropsychiatric diseases involving impairment in motivation.

Paris MEM: a study protocol for an effectiveness and efficiency trial on the treatment of traumatic stress in France after the 2015-16 terrorist attacks.

Background: The Paris and Nice terrorist attacks affected a thousand of trauma victims and first-line responders. Because there were concerns that this might represent the first of several attacks, there was a need to quickly enhance the local capacities to treat a large number of individuals suffering from trauma-related disorders. Since Reconsolidation Therapy (RT) is brief, relatively easy to learn, well tolerated and effective, it appeared as the ideal first-line treatment to teach to clinicians in this context.

Metformin Promotes Anxiolytic and Antidepressant-Like Responses in Insulin-Resistant Mice by Decreasing Circulating Branched-Chain Amino Acids.

Epidemiological studies indicate that insulin resistance (IR), a hallmark of type 2 diabetes, is associated with an increased risk of major depression. Here, we demonstrated that male mice fed a high-fat diet (HFD) exhibited peripheral metabolic impairments reminiscent of IR accompanied by elevated circulating levels of branched-chain amino acids (BCAAs), whereas both parameters were normalized by chronic treatment with metformin (Met). Given the role of BCAAs in the regulation of tryptophan influx into the brain, we then explored the activity of the serotonin (5-HT) system.

Decrease in Operant Responding Under Obesogenic Diet Exposure is not Related to Deficits in Incentive or Hedonic Processes.

Objective: A growing body of evidence suggests that obesity could result from alterations in reward processing. In rodent models, chronic exposure to an obesogenic diet leads to blunted dopamine signaling and related incentive responding. This study aimed to determine which reward-related behavioral dimensions are actually impacted by obesogenic diet exposure.

Can We Define Termination Of Resuscitation Criteria In Out-Of-Hospital Hanging?

Objective: Survival rate of cardiac arrest due to hanging (H-CA) victims is low. Hence, this leads to the question of the utility of resuscitation in these patients. The objective was to investigate whether there are predictive criteria for survival with a good neurological outcome or predictive criteria for non-survival or survival with a poor neurological outcome enabling us to define the termination of resuscitation rules in these patients.

Blunted Dopamine Transmission in Addiction: Potential Mechanisms and Implications for Behavior.

Positron emission tomography (PET) imaging consistently shows blunted striatal dopamine release and decreased dopamine D2 receptor availability in addiction. Here, we review the preclinical and clinical studies indicating that this neurobiological phenotype is likely to be both a consequence of chronic drug consumption and a vulnerability factor in the development of addiction. We propose that, behaviorally, blunted striatal dopamine transmission could reflect the increased impulsivity and altered cost/benefit computations that are associated with addiction.

Factors Affecting the Agreement Between Emergency Psychiatrists and General Practitioners Regarding Involuntary Psychiatric Hospitalizations.

Important discrepancies exist between physicians in deciding when to perform involuntary hospitalization measures (IHMs). The factors underlying these differences are poorly known.We conducted a two-year single-center retrospective study in France on patients who were referred to the emergency department (ED) with an IHM certificate written by a private-practice General Practitioner (GP).

Mortality of people suffering from mental illness: a study of a cohort of patients hospitalised in psychiatry in the north of France.

Background: The mortality of people suffering from psychiatric illnesses is far higher than that of the general population, all categories of diagnosis combined; mortality statistics can be used as an index of quality of care. The aim of this study was to assess the all-cause mortality in psychiatric patients covering all diagnostic groups.

Methods: The living or deceased status of 4,417 patients of majority age hospitalised in a public mental health establishment between 2004 and 2007 were requested from French National Institute for Statistics and Economic Studies on 1st January 2011.

[Advanced directives in psychiatry: A review of the qualitative literature, a state-of-the-art and viewpoints].

Background: Advance Directives are written documents, which are used for people to notify their preference for a future situation when they are unable to give their consent. In psychiatry, psychiatric advance directives (PADs) can be used for patients with chronic psychotic disorders such as schizophrenia, or a bipolar disorder. PADs give the patient an opportunity to state wishes in advance about his/her treatment when he/she is in an acute state of illness.
