AIM OF THE STUDY
The past twenty years have seen a rise in cocaine-related statistics in France, including cocaine use in the general population, emergency ward presentations of acute cocaine intoxication, cocaine use disorders related outpatient appointments and cocaine-related deaths. This study's objectives were to describe trends in patients' admission for specific cocaine detoxification as well as changes in patients' characteristics in the Assistance publique-Hôpitaux de Paris (AP-HP) hospitals group located in Paris region, France.
METHODS
We reviewed the international classification of diseases 10 edition (ICD-10) discharge codes of the AP-HP hospitals group between 2011 and 2021. In addition, medical reports of the largest addiction medicine ward were also analysed for changes across the years 2009, 2014, 2019 and 2022.
RESULTS
The regional database showed an almost 3-fold increase in cocaine-related disorders discharge codes between 2011 and 2019. This occurred due to a rise in hospital stays for cocaine dependence or cocaine acute intoxication prior to the fall in levels of inpatient stays associated with the coronavirus disease 2019 (COVID-19) pandemic. The in-depth analysis of inpatients' stays in the specialized addiction medicine ward also showed an increase in admissions for cocaine detoxification programs, with a prevalence of 1.19% in 2009 to 15.73% in 2022 (P=1.44×10). Inpatient characteristics showed significant changes, especially in 2022, namely: more daily users, less intravenous administration and less comorbid illicit substances use disorders, with heightened levels of cured hepatitis C patients (P<0.05). Inpatient prescriptions were primarily dopaminergic antagonists with sedatives properties (cyamemazine, loxapine and chlorpromazine), dopamine-receptors partial agonist (aripiprazole) and serotonin reuptake inhibitors.
CONCLUSION
The referral to hospital care for cocaine detoxification has increased in Paris region since 2011, coupled with changes in inpatients' characteristics. This trend has significant implications for the management of inpatient hospital services.

BACKGROUND
Sleep problems are common and related to a worse quality of life in patients with schizophrenia. Almost all patients with schizophrenia use antipsychotic medications, which usually increase sleep. Still, the differences in subjective sleep outcomes between different antipsychotic medications are not entirely clear.
METHODS
This study assessed 5466 patients with schizophrenia and is part of the nationwide Finnish SUPER study. We examined how the five most common antipsychotic medications (clozapine, olanzapine, quetiapine, aripiprazole, and risperidone) associate with questionnaire-based sleep problems in logistic regression analyses, including head-to-head analyses between different antipsychotic medications. The sleep problems were difficulties initiating sleep, early morning awakenings, fatigue, poor sleep quality, short (≤6 h) and long sleep duration (≥10 h).
RESULTS
The average number of antipsychotic medications was 1.59 per patient. Clozapine was associated with long sleep duration (49.0 % of clozapine users vs 30.2 % of other patients, OR = 2.05, 95 % CI 1.83-2.30, p < .001). Olanzapine and risperidone were in head-to-head analyses associated with less sleep problems than patients using aripiprazole, quetiapine, or no antipsychotic medication. Aripiprazole and quetiapine were associated with more insomnia symptoms and poorer sleep quality. Patients without antipsychotic medications (N = 159) had poorer sleep quality than patients with antipsychotic use, and short sleep duration was common (21.5 % of patients not using antipsychotics vs 7.8 % of patients using antipsychotics, OR = 2.97, 95 % CI 1.98-4.44, p < .001).
CONCLUSIONS
Prevalence of sleep problems is markedly related to the antipsychotic medication the patient uses. These findings underline the importance of considering and assessing sleep problems when treating schizophrenia patients with antipsychotics.

N -n-butyl haloperidol iodide (F 2 ), a derivative of haloperidol developed by our group, exhibits potent antioxidative properties and confers protection against cardiac ischemia/reperfusion (I/R) injury. The protective mechanisms by which F 2 ameliorates I/R injury remain obscure. The activation of nuclear factor erythroid 2-related factor 2 (Nrf2), a key transcription factor transactivating many antioxidative genes, also attenuates I/R-induced myocardial damage. The present study investigated whether the cardioprotective effect of F 2 depends on Nrf2 using a mouse heart I/R model. F 2 (0.1, 0.2 or 0.4 mg/kg) or vehicle was intravenously injected to mice 5 minutes before reperfusion. Systemic administration of 0.4 mg/kg F 2 led to a significant reduction in I/R injury, which was accompanied by enhanced activation of Nrf2 signaling. The cardioprotection conferred by F 2 was largely abrogated in Nrf2-deficient mice. Importantly, we found F 2 -induced activation of Nrf2 is silent information regulator of transcription 1 (SIRT1)-dependent, as pharmacologically inhibiting SIRT1 by the specific inhibitor EX527 blocked Nrf2 activation. Moreover, F 2 -upregulated expression of SIRT1 was also Nrf2-dependent, as Nrf2 deficiency inhibited SIRT1 upregulation. These results indicate that SIRT1-Nrf2 signaling loop activation is indispensable for the protective effect of F 2 against myocardial I/R injury and may provide new insights for the treatment of ischemic heart disease.

Meta-Analysis
BACKGROUND
Vomiting is one of the most common adverse events of chemotherapy. The purpose of this study was to systematically review the clinical efficacy of acupoint injection of metoclopramide in the treatment of post-chemotherapy vomiting.
METHODS
We searched 4 general English databases and 4 conventional Chinese databases, all with a time frame from database creation to December 2022. The retrieved clinical trials of acupoint injection of metoclopramide for post-chemotherapy vomiting were then subjected to meta-analysis and trial sequential analysis.
RESULTS
A total of 12 studies were included, with a total sample size of 965 cases. Meta-analysis showed that acupoint injection of metoclopramide was effective in improving anti-vomiting effective rate [odds ratio = 5.67, 95% confidence interval = (3.80,8.47), P < .00001] compared with intramuscular/intravenous injection, and trial sequential analysis showed that this benefit was conclusive. Subgroup analysis demonstrated that acupoint injection significantly improved the anti-vomiting effective rate at doses of 10 mg qd, 20 mg qd, and 30 mg qd, as well as at durations of 1 day and 5 days. Subgroup analysis also indicated that injection at the Zusanli acupoint significantly increased the anti-vomiting effective rate, while injection at the Neiguan acupoint had an anti-vomiting effective rate comparable to that of the control group. Harbord regression showed no significant publication bias (P = .730).
CONCLUSION
Acupoint injection of metoclopramide for post-chemotherapy vomiting is more effective than intramuscular and intravenous injections and is not limited by dose or duration of treatment, which may be the preferred way of administration.

Psychosis is characterized by a diminished ability of the brain to distinguish externally driven activity patterns from self-generated activity patterns. Antipsychotic drugs are a class of small molecules with relatively broad binding affinity for a variety of neuromodulator receptors that, in humans, can prevent or ameliorate psychosis. How these drugs influence the function of cortical circuits, and in particular their ability to distinguish between externally and self-generated activity patterns, is still largely unclear. To have experimental control over self-generated sensory feedback, we used a virtual reality environment in which the coupling between movement and visual feedback can be altered. We then used widefield calcium imaging to determine the cell type-specific functional effects of antipsychotic drugs in mouse dorsal cortex under different conditions of visuomotor coupling. By comparing cell type-specific activation patterns between locomotion onsets that were experimentally coupled to self-generated visual feedback and locomotion onsets that were not coupled, we show that deep cortical layers were differentially activated in these two conditions. We then show that the antipsychotic drug clozapine disrupted visuomotor integration at locomotion onsets also primarily in deep cortical layers. Given that one of the key components of visuomotor integration in cortex is long-range cortico-cortical connections, we tested whether the effect of clozapine was detectable in the correlation structure of activity patterns across dorsal cortex. We found that clozapine as well as two other antipsychotic drugs, aripiprazole and haloperidol, resulted in a strong reduction in correlations of layer 5 activity between cortical areas and impaired the spread of visuomotor prediction errors generated in visual cortex. Our results are consistent with the interpretation that a major functional effect of antipsychotic drugs is a selective alteration of long-range layer 5-mediated communication.

This study evaluates the antiallodynic and antihyperalgesic effects of LMH-2, a new haloperidol (HAL) analog that acts as sigma-1 receptor (σ1 R) antagonist, in diabetic mice using a model of neuropathic pain induced by chronic hyperglycemia. Additionally, we compared its effects with those of HAL. Hyperglycemia was induced in mice by nicotinamide-streptozotocin administration (NA-STZ, 50-130 mg/kg). Four weeks later, mechanical allodynia was assessed using the up-down method, and hyperalgesia was evoked with formalin 0.5%. We evaluated antiallodynic and antihyperalgesic effects of LMH-2 (5.6-56.2 mg/kg), HAL (0.018-0.18 mg/kg) and gabapentin (GBP, 5.6-56.2 mg/kg). The results showed that LMH-2 had a more significant antiallodynic effect compared to HAL and GBP (90.4±8.7 vs 75.1±3.1 and 41.9±2.3%, respectively; P<0.05), as well as an antihyperalgesic effect (96.3±1.2 vs 86.9±7.41 and 86.9±4.8%, respectively; P<0.05). Moreover, the antiallodynic and antihyperalgesic effect of both LMH-2 and HAL were completely abolished by PRE-084 (σ1 R agonist); and partially by pramipexole (a D-like receptor agonist). Finally, the effect of all treatments on the rotarod test, barra, open field and exploratory behaviors showed that LMH-2 did not alter the animals' balance or the exploratory behavior, unlike as HAL or GBP. The molecular docking included indicate that LMH-2 has lower affinity to the DR than HAL. These results provide evidence that LMH-2 exerts its antinociceptive effects as a σ1 R antagonist without the adverse effects induced by HAL or GBP. Consequently, LMH-2 can be considered a good and safe strategy for treating neuropathic pain caused by hyperglycemia in patients with diabetes.

BACKGROUND
The Calcium-sensing receptor (CaSR) participates in the regulation of gastrointestinal (GI) motility under normal conditions and might be involved in the regulation of GI dysmotility in patients with Parkinson's disease (PD).
METHODS
CaSR antagonist-NPS-2143 was applied in in vivo and ex vivo experiments to study the effect and underlying mechanisms of CaSR inhibition on GI dysmotility in the MPTP-induced PD mouse model.
FINDINGS
Oral intake of NPS-2143 promoted GI motility in PD mice as shown by the increased gastric emptying rate and shortened whole gut transit time together with improved weight and water content in the feces of PD mice, and the lack of influence on normal mice. Meanwhile, the number of cholinergic neurons, the proportion of serotonergic neurons, as well as the levels of acetylcholine and serotonin increased, but the numbers of nitrergic and tyrosine hydroxylase immunoreactive neurons, and the levels of nitric oxide synthase and dopamine decreased in the myenteric plexus in the gastric antrum and colon of PD mice in response to NPS-2143 treatment. Furthermore, the numbers of c-fos positive neurons in the nucleus tractus solitarius (NTS) and cholinergic neurons in the dorsal motor nucleus of the vagus (DMV) increased in NPS-2143 treated PD mice, suggesting the involvement of both the enteric (ENS) and central (CNS) nervous systems. However, ex vivo results showed that NPS-2143 directly inhibited the contractility of antral and colonic strips in PD mice via a non-ENS mediated mechanism. Further studies revealed that NPS-2143 directly inhibited the voltage gated Ca channels, which might, at least in part, explain its direct inhibitory effects on the GI muscle strips.
INTERPRETATION
CaSR inhibition by its antagonist ameliorated GI dysmotility in PD mice via coordinated neuronal regulation by both ENS and CNS in vivo, although the direct effects of CaSR inhibition on GI muscle strips were suppressive.

In this article, we present the case of an adult patient, whose main problem is episodes of fantasizing and rocking lasting up to 12 hours a day and completely preventing school development. The nature of the disorder in the patient is related to the sinking into fantasies, and not typical obsessions as in OCD. The patient was previously treated with drugs from the SSRI group, neuroleptics (without aripiprazole) and methylphenidate. Only methylphenidate showed some improvement; however, it made the patient feel ‟stiff in thinking". The patient was hospitalized because of a suicide attempt, which, as it later turned out, was self-harm with no intention of killing himself. During hospitalization, a differential diagnosis was performed and the diagnosis of Asperger's syndrome was made, which was accompanied by immersion in the world of one's fantasies and stereotypical behavior. The patient was administered aripiprazole at a dose of 15 mg/d and after three weeks, a significant improvement in health was achieved, including a reduction in the duration of episodes from several hours to several dozen seconds. The drug is well tolerated by the patient. The patient was discharged from the hospital and continues his school education. In the article, we present single case reports in which similar spectacular results were achieved in similar cases. We also describe a possible physiological explanation for this response to this drug.

Neuroleptic malignant syndrome (NMS), which most often occurs after the use of antipsychotics, is a rare but life-threatening condition. In this article, a 56-year-old male patient with a diagnosis of bipolar affective disorder (BPD) who developed NMS after a COVID-19 infection will be presented. The patient had been brought to the emergency room with high fever, fatigue, and slowness of movements that had been going on for two days. The examination revealed tachycardia, tachypnea, lethargy and rigidity. Upon further investigation the COVID-19 test came out positive and the serum levels of creatine kinase were considerably high. He was admitted to the psychiatric ward with diagnoses of COVID-19 infection and NMS. COVID-19 infection might have been a risk factor for NMS in this patient. Especially in patients who are taking antipsychotic drugs, if COVID-19 is present, the risk of NMS should be taken into consideration.
