NASA’s all-sky survey mission, the Transiting Exoplanet Survey Satellite (TESS), is specifically engineered to detect exoplanets that transit bright stars. Thus far, TESS has successfully identified approximately 400 transiting exoplanets, in addition to roughly 6 000 candidate exoplanets pending confirmation. In this study, we present the results of our ongoing project, the Validation of Transiting Exoplanets using Statistical Tools (VaTEST). Our dedicated effort is focused on the confirmation and characterisation of new exoplanets through the application of statistical validation tools. Through a combination of ground-based telescope data, high-resolution imaging, and the utilisation of the statistical validation tool known as TRICERATOPS, we have successfully discovered eight potential super-Earths. These planets bear the designations: TOI-238b (1.61$^{+0.09} _{-0.10}$ R$_\oplus$), TOI-771b (1.42$^{+0.11} _{-0.09}$ R$_\oplus$), TOI-871b (1.66$^{+0.11} _{-0.11}$ R$_\oplus$), TOI-1467b (1.83$^{+0.16} _{-0.15}$ R$_\oplus$), TOI-1739b (1.69$^{+0.10} _{-0.08}$ R$_\oplus$), TOI-2068b (1.82$^{+0.16} _{-0.15}$ R$_\oplus$), TOI-4559b (1.42$^{+0.13} _{-0.11}$ R$_\oplus$), and TOI-5799b (1.62$^{+0.19} _{-0.13}$ R$_\oplus$). Among all these planets, six of them fall within the region known as ‘keystone planets’, which makes them particularly interesting for study. Based on the location of TOI-771b and TOI-4559b below the radius valley we characterised them as likely super-Earths, though radial velocity mass measurements for these planets will provide more details about their characterisation. It is noteworthy that planets within the size range investigated herein are absent from our own solar system, making their study crucial for gaining insights into the evolutionary stages between Earth and Neptune.

Background
The prevalence of medical illnesses is high among patients with psychiatric disorders. The current study aimed to investigate multi-comorbidity in patients with psychiatric disorders in comparison to the general population. Secondary aims were to investigate factors associated with metabolic syndrome and treatment appropriateness of mental disorders.
MethodsThe sample included 54,826 subjects (64.73% females; 34.15% males; 1.11% nonbinary gender) from 40 countries (COMET-G study). The analysis was based on the registration of previous history that could serve as a fair approximation for the lifetime prevalence of various medical conditions.
ResultsAbout 24.5% reported a history of somatic and 26.14% of mental disorders. Mental disorders were by far the most prevalent group of medical conditions. Comorbidity of any somatic with any mental disorder was reported by 8.21%. One-third to almost two-thirds of somatic patients were also suffering from a mental disorder depending on the severity and multicomorbidity. Bipolar and psychotic patients and to a lesser extent depressives, manifested an earlier (15–20 years) manifestation of somatic multicomorbidity, severe disability, and probably earlier death. The overwhelming majority of patients with mental disorders were not receiving treatment or were being treated in a way that was not recommended. Antipsychotics and antidepressants were not related to the development of metabolic syndrome.
ConclusionsThe finding that one-third to almost two-thirds of somatic patients also suffered from a mental disorder strongly suggests that psychiatry is the field with the most trans-specialty and interdisciplinary value and application points to the importance of teaching psychiatry and mental health in medical schools and also to the need for more technocratically oriented training of psychiatric residents.

The current study evaluated alternative sources of nutrients to improve the soil fertility status and yield of maize-wheat succession in Southern Brazil. The treatments were: T1: no fertilization; T2: liming with dolomitic marble; T3: alternative liming (AL) with limestone interbedded with shale; T4: AL + 50% P - with Arad natural phosphate (P-ANP) + 50% P – triple superphosphate (P-TSP); T5: AL + 100% P-ANP; T6: AL + 100% P-ANP + 100% K-rich monzogranite; T7: AL + 100% P-ANP + 100% N (50% N from tung pressed cake (N-TPC) + 50% N-urea); T8: AL + 100% P-ANP + 100% K-rich monzogranite + 100% N (50% N-TPC + 50% N-Urea) + 100% S; T9: AL + regional average rate of NPK (5-20-20) formulation. Except for T7 and T8, all treatments received the full recommended rate of N through Urea. Immediate and residual effects were evaluated over 2.5 years (90, 360 and 900 days) on soil fertility and maize - wheat yield. The limestone interbedded with shale released Ca, Mg and corrected soil acidity similarly to dolomitic marble. The fertilization strategies used in T4, T7 and T8 presented the highest cumulative productivities while T3 (U$ = 1223), T9 (U$ = 1174) and T4 (U$ = 1122) resulted in higher profits than the other evaluated fertilization strategies. The limestone interbedded with shale (T3), alone or combined with 50% of P-ANP + 50% of P – TSP (T4) provided the best economical and technical results, highlighting the potential of selected alternative regional sources for soil fertility improvement and plant-nutrients supply.

The U.S. Department of Agriculture–Agricultural Research Service (USDA-ARS) has been a leader in weed science research covering topics ranging from the development and use of integrated weed management (IWM) tactics to basic mechanistic studies, including biotic resistance of desirable plant communities and herbicide resistance. ARS weed scientists have worked in agricultural and natural ecosystems, including agronomic and horticultural crops, pastures, forests, wild lands, aquatic habitats, wetlands, and riparian areas. Through strong partnerships with academia, state agencies, private industry, and numerous federal programs, ARS weed scientists have made contributions to discoveries in the newest fields of robotics and genetics, as well as the traditional and fundamental subjects of weed–crop competition and physiology and integration of weed control tactics and practices. Weed science at ARS is often overshadowed by other research topics; thus, few are aware of the long history of ARS weed science and its important contributions. This review is the result of a symposium held at the Weed Science Society of America’s 62nd Annual Meeting in 2022 that included 10 separate presentations in a virtual Weed Science Webinar Series. The overarching themes of management tactics (IWM, biological control, and automation), basic mechanisms (competition, invasive plant genetics, and herbicide resistance), and ecosystem impacts (invasive plant spread, climate change, conservation, and restoration) represent core ARS weed science research that is dynamic and efficacious and has been a significant component of the agency’s national and international efforts. This review highlights current studies and future directions that exemplify the science and collaborative relationships both within and outside ARS. Given the constraints of weeds and invasive plants on all aspects of food, feed, and fiber systems, there is an acknowledged need to face new challenges, including agriculture and natural resources sustainability, economic resilience and reliability, and societal health and well-being.

Introduction
Intensive home treatment (IHT) for people experiencing a mental health crisis has been progressively established in many western countries as an alternative to in-ward admission. But is this a real alternative? We previously reported that patients treated in our IHT unit only differ from those voluntarily admitted to hospital in suicidal risk and severe behaviour disorders (not in other factors such as clinical severity) (Martín-Blanco et al., Rev Psiquiatr Salud Ment 2022;15:213-5). Now we are interested in disentangle if those patients who used to require inward management can be successfully treated at home.
ObjectivesTo describe subsequent treatment trajectories of the first 1000 admissions to our IHT unit and to compare clinical characteristics among the different groups of trajectories.
MethodsRetrospective cohort study. Subsequent treatment trajectories were collected from December 2016 to October 2022 and classified: absence, hospital, IHT, and mixed (hospital and IHT). Statistical significance was tested by means of ANOVA or Kruskal-Wallis test for quantitative variables (corrected for multiple comparisons) and chi-square tests for qualitative variables.
ResultsTables 1 shows the characteristics of the whole sample. Of the 1000 IHT admissions, 12.1% needed subsequent hospital admission(s), 12.7% IHT admission(s), and 9.3% mixed admission(s). There were no differences among these groups in median severity at IHT admission, but there were differences in the number of previous admissions (p=0.0001): the group with no subsequent admissions had less previous admissions than the other groups (pBonf<0.0001), and the group with subsequent IHT admissions had less than the group with mixed admissions (pBonf=0.0123). There were differences between groups regarding distribution of diagnoses (p<0.0001) (Fig. 1). When considering subsequent admissions by diagnosis, there were differences in severity at IHT admission (p=0.0068) and in number of previous hospitalizations (p<0.0001) (Fig. 2).

Introduction
COVID-19 pandemic along with its social restrictions changed our burial practices and the way we bury our dead. In consequence, it affected people’s experiences and traditions which could lead to severe, persistent, or disabling grief.
Thereby, it is relevant to understand how someone may be more susceptible to developing pathological grief and what can we do to prevent it.
ObjectivesTo assess the risk of Prolonged Grief Disorder (PGD) in family members of patients who died from COVID-19 infection and identify possible risk factors.
MethodsProspectively, we performed follow-up interviews conducted with family members of all patients who died from COVID-19 infection in 2020 at our hospital. The sample was characterized, and clinical follow-up was performed for at least 6 months after the date of death. By that time, the PG-13 scale was applied.
ResultsA total of 269 individuals who had some type of relationship with patients who died from COVID-19 were included, with 68% being female with a mean age of 53.7 years.
After clinical follow-up, 10.8% of the patients met the diagnostic criteria for PGD.
Regarding the degree of kinship, the only predictor of PGD was “spouse” (OR 11,236, [4,762; 26,316]; p < 0,001). A closer and more regular interaction with the deceased was also associated with an increase in PDG (OR 5.682, [1.314; 24.390] p = 0.009).
Feelings of denial and guilt by the time of death notification were also risk predictors for PGD (OR 2,412, [1,091; 5,332] p = 0,026) and OR 2,888, [1,244; 6,703] p = 0,011, respectively).
The impossibility of being present at the funeral was associated with a risk of about 3 times higher of developing PGD (OR 3,817 [1,727; 8,403] p < 0,001).
Older age (p<0,001) and lower educational qualification (p=0,003) were also presented as risk factors.
Other characteristics including gender, marital status, previous suicide attempts, psychiatric or consumption history, previous significant bereavement or the social and family support of the person contacted were not predictors of PGD.
ConclusionsThe present prospective study made it possible to reinforce and support the way in which the COVID-19 pandemic, associated with significant social modifications, changed the way people experience grief.

Introduction
The semiological spectrum that encompasses musical imagery is a very confusing field, as it is often difficult to understand the nature of the underlying psychopathological phenomenon from the patient’s description.
ObjectivesThe purpose of the authors is to explore reviewing, distinguishing and organizing the concepts such as Intrusive musical imagery, musical obsessions, musical hallucinations, pseudohallucinations and musical palinacousis.
MethodsA brief non-systematized review is presented, using the literature available on PubMed and Google Scholar.
ResultsIntrusive musical imagery (earworms, ohrwurms, or involuntary musical imagery) occur in more than 85% of general population, without pathology or ear disease. It involves the involuntary repetition of 15-30 seconds of a fragment of music/tune, persisting like a looping soundtrack, not being aversive.
Musical obsessions are a rare form of intrusive imagery, occurring either with other symptoms of Obsessive Compulsive Disorder or isolated (“The stuck song syndrome”). It is recurrent, persistent, intrusive, unintentional, time consuming and causes distress or functional impairment (although not as ego-dystonic and aversive as usually intrusive visual imagery are); preserved insight.
Musical hallucinations occur only in 0,16% in a general hospital; they can be linked to psychiatric diseases, but they are more common in neurological diseases (cerebral lesions, Parkinson’s disease, delirium, drug induced…). They are reported to with less controllability, less lyrical content, and lower familiarity, than other forms of inner music; are perceived to arise from an external source and are interpreted as veridical.
Musical Pseudohallucinations can arise after severe hearing loss, in hallucinogen intoxication and in psychotic or non-psychotic disorders (as dissociative states or in borderline personality disorder). They occur in inner/subjective space, but insight can fluctuate.
Musical palinacousis is associated with electroencephalogram and neuroimaging abnormalities, linked to structural brain pathology. There is perseveration (echoing) of an external auditory stimulus occurs after cessation of the stimulus.
ConclusionsA rash classification can lead to misdiagnosis (for e.g. interpreting obsessive symptoms as hallucinatory phenomena or rendering an organic pathology undiagnosed) and the institution of inappropriate therapy. It is important to carefully explore these musical imagery phenomena when patients present these complaints, taking some time to characterize them.

Introduction
Psychiatry has been diagnosing its pathologies through the evaluation of the symptoms reported by patients, relying on a few complementary exams to exclude organic causes. Studies about transcranial magnetic stimulation and electroencephalography (TMS-EEG) are bringing, from a clinical point of view, crucial information to characterize the different pathophysiological biomarkers of the psychiatric diseases, leading not only to the evolution of diagnosis, but also to an improved, more individualized treatment.
ObjectivesCharacterizing the state of the art of TMS-EEG and its use in psychiatric diagnosis and treatments of different diseases.
MethodsWe undertook a narrative literature review by performing a search on PubMed for English-written articles from the last 10 years. The query used was “TMS-EEG”; “TMS-EEG” AND “Schizophrenia” OR “Major Depressive Disorder” OR “Bipolar Disorder”.
ResultsTranscranial magnetic stimulation (TMS) is a safe and reliable method of non-invasive brain stimulation that allows for the local activation of cortical areas through electromagnetic induction. When combining this method with electroencephalography (EEG), it enables the underlying mechanisms of brain diseases.
TMS is a powerful therapeutic technic in Major Depressive Disorder (MDD). The literature refers to an enhanced N45 and N100 amplitude, which indicates a baseline cortical inhibition that can indicate a depressed state, which can be used as a clinical biomarker to evaluate TMS treatments.
In Schizophrenia (SCZ), TMS-EEG reveals a decreased cortical inhibition and excitation. Indices of inhibition and excitation reductions were also related to cognitive deficits.
The current studies regarding Bipolar Disorder (BD) are not so consistent, revealing that there are shared neural pathways with MDD and SCZ. This is a pathology often misdiagnosed with MDD, so biomarkers would help to diagnose BD earlier and improve its prognostic.
ConclusionsTMS-EEG can be used to provide more accurate neural targets, leading to more powerful and personalized interventions in psychiatric disorders, as well as more accurate diagnoses.
As for future studies, it would be relevant to assess not only TMS treatment effects, but also pharmacological results in these different pathologies.

Introduction
In spite of the progress observed in the last decade particularly in the field of the neurosciences, areas of controversy and incomplete concepts still remain in psychiatry. One relates to the study the heterogeneous group of schizophrenic spectrum functional psychosis that arise along the neurophysiological aging process. Kraepelin first used the term paraphrenia in 1912, to describe a psychotic disorder with much lighter impairment of emotion and volition, minimal to no cognitive deterioration (dementia) and personality preservation compared to dementia praecox. However, since its first descriptions, late-onset psychoses have received different descriptions and definitions.
ObjectivesBrief review of the evolution of paraphrenia concept, focusing not only on pioneering currents, but also articulating it with recent conclusions on late-onset psychoses.
MethodsSystematic revision of literature.
ResultsAfter Kreapelin pioneerism, Bleuler and Mayer-Gross would contribute to the weakening and disruption of the Kraepelinian concept of paraphrenia. In the first half of the 20th century, psychiatry was moving towards the dissolution of this concept. British psychiatrists would later rehabilitate the concept of paraphrenia but to designate a very late-onset variant of schizophrenia - late paraphrenia. This influenced the International Diseases Classifications (ICD), and the 8th edition was the first to consider paraphrenia as a subtype of paranoid schizophrenia.
By the end of the 20th century, both ICD-10 and various editions of DSM since DSM-III-TR (inclusive) omitted the category of paraphrenia, allowing the super-inclusiveness of the schizophrenia category and discouraging research on the theme.
In the late 20th century, late paraphrenia was conceived as a group of heterogeneous disorders that included paranoid and organic psychosis. To date, the term very late onset schizophrenia-like psychosis is the term used to replace late paraphrenia.
ConclusionsThe nosological consecration of paraphrenia suffered several misfortunes over the last century. The schizophrenic psychosis “black-hole” conceived at the same time contributed to this concealment. In addition, modern pharmacology also allowed the neuroleptization and homogenization of disorders with psychotic symptoms which led to the devaluation of some diagnostic possibilities in the “neighborhood” of schizophrenia.
We propose a nosological frame composed of two distinct entities: one based on a neurodevelopment disorder - schizophrenia - with insidious onset at a younger age, with a hereditary background and greater global deterioration, an the other, with a neurodegenerative basis - paraphrenia - with an abrupt and later onset, less contribution of genetic factors, greater preservation and lower probability of dementia development.

Introduction
Bipolar disorder (BD) is a chronic mental disorder characterized by mood instability1. BD is further related to neurocognitive and functional disruptions that remain remarkably stable even when patients are euthymic, leading to poor well-being and quality of life. Mindfulness means paying attention on purpose, in the present moment, and involves different facets such as observing, describing, acting with awareness, non-judging and non-reacting of inner experience. It remains unclear whether mindfulness and its specific facets are differentially associated with different aspects of attention and trait impulsivity in individuals with BD.
ObjectivesTo examine associations between different mindfulness facets, and different aspects of attention and trait impulsivity in BD.
MethodsThis study was approved by the Hospital Clínic Ethics and Research Board (HCB/2017/0432). After informed consent, 94 outpatients, M age = 45.57, SD = 9.8, range 19-61 years, 41.5% Male, 63.8% BD-I according to DSM-5 criteria, in partial or total remission based on Young Mania Rating Scale (YMRS; M = 1.81, SD = 2.11) and Hamilton Depression Rating Scale (HDRS; M = 5.46, SD = 3.71) were enrolled in this study. Participants were evaluated using the Five Facet Mindfulness Questionnaire (FFMQ) to assess Mindfulness, the Trail Making Test (TMT-A) and the Conner’s Continuous Performance test (CPT-II) to assess Attention, and the Barratt Impulsiveness Scale (BIS-11) to assess Impulsivity. Pearson correlations were performed, and statistical significance was evaluated two-sided at the 5% threshold.
ResultsMindfulness-Describing was negatively associated with Cognitive and Non-Planning Impulsivity (r = -.43 and -.28, p < .001), Mindfulness-Acting with Awareness was negatively associated with Cognitive, Motor and Non-Planning Impulsivity (r = -.27 to -.45, p < .001), Mindfulness Non-Judging (r = -.33 and -.34, p < .001) and Non-Reacting (r = -.30 and -.46, p < .001) of inner experience were negatively associated with Cognitive and Motor Impulsivity. No associations were found between neither Mindfulness nor Impulsivity with any aspects of Attention.
ConclusionsPreliminary findings suggest that better performance in specific facets of mindfulness (describing, acting with awareness, non-judging or reacting of inner experience) may be related to a decrease in different aspects of trait impulsivity. Further longitudinal and interventional research is needed on underlying mechanisms. Nonetheless, our study suggests the need for including mindfulness-based approaches to improve behavioral and functional outcomes for those with BD.

Introduction
Psychotic symptoms have long been known to show up earlier in life, typically during adolescence and early adulthood. Late Onset Psychosis (LOP), in which symptoms start between 40 and 60 years of age, and Very Late Onset Psychosis (VLOP), in which onset of symptoms happens after 60 years of age, although classically rare, have had a growing prevalence in the last decades.
ObjectivesTo access the definition and main etiologies of LOP and VLOP, based on the current literature.
MethodsNon-systematic review of literature using the terms “late onset psychosis” and “very late onset psychosis”. Case report of a patient who was admitted and treated in our inward patient field.
Results51-year-old female patient. She is divorced (two previous marriages) and has two daughters (26 and 16, respectively). She was brought by police officers because of behavior problems at the shelter where she was living. She was evicted from the house she was living in because of delay in paying the rent. On observation, she verbalizes persecutory and prejudicial delusions and auditory hallucinations on the 2nd and 3rd person (commenting voices) with at least 5 years of duration. She was hospitalized for almost 3 months, with slow but progressive clinical improvement on haloperidol 7,5mg/day. At the date of discharge, she did not spontaneously verbalize her symptoms, although she did not recognize them as delusional. Recent studies have shown that the prevalence of Schizophrenia in the typical age range is 75-80%, which means that an important proportion of diagnosis is made after that age span. Primary causes of LOP and VLOP are schizophrenia (of late onset), schizophrenia-like very late onset psychosis, delusion disorder, unipolar depression with psychotic symptoms and bipolar disorder. Secondary causes should also be considered, such as delirium, dementia (Alzheimer’s, Lewi bodies and vascular), and substances abuse; even more rare, other conditions should be considered, as cerebrovascular accident, encephalitis, epilepsy, and multiple sclerosis.
ConclusionsLOP and VLOP have been a growing diagnosis in the past decades. In the assessment of these patients, we must consider the importance of secondary etiologies besides the primary psychiatric ones. Primary psychosis is a diagnosis of exclusion, and the clinician must rule out secondary causes. Recent data point out these symptoms as markers for an increased risk of dementia in these patients. Further research involving individuals with LOP and VLOPs is required to increase the evidence base for treatment and improve outcomes of care.

Introduction
An inpatient suicide is a tragic event that, despite not very prevalent, should not be overlooked. It occurs in 250 in 100 000 psychiatric hospital admissions (which represents a suicide risk fifteen times greater than general population) and in 1.7-1.9 in 100 000 in general hospitals (4-5 times greater risk). Together they constitute 5-6% of all suicides.
ObjectivesThe purpose of the authors is to explore the epidemiology, the risk factors and the prevention of suicide in inpatient setting.
MethodsA brief non-systematized review is presented, using the literature available on PubMed and Google Scholar.
ResultsThe risk was higher at admission (first week) and immediately after discharge (first 24 hours, up to two weeks).
It was found to be correlated to pour staffing, an increased number of patients with severe mental illnesses and accessibility to lethal means. Many risk factors were identified, some of them specific to context. Risk Factors at admission in a psychiatric hospital – personal or familiar suicide history, schizophrenia or mood disorder, alcohol use, involuntary admission, living alone, absence from the service without permission. Later till discharge - personal suicide history (or attempts after admission), relational conflicts, unemployment, living alone, lack of discharge planning and lack of contact in the immediate post-discharge period. In General Hospitals – chronicity and severity of somatic disease, poor coping strategies, psychiatric comorbidities and lack of liaison psychiatry.
Strategies to prevent inpatient suicide should take in environmental modification (specific to environment and specific to patient – as planned levels of supervision), optimisation of the care of the patients at suicidal risk, staff education and involvement of families in care. There are few studies on the efficacy of pharmacotherapy on reducing suicidal ideation in inpatients (just for clozapine and ketamine); some psychotherapies show promising results. The post-suicide approach cannot be neglected, whether in supporting the family, the team involved and even other patients.
ConclusionsThe assumption of the predictive and preventive value of the risk assessment has been under scrutiny. Depressed mood and a prior history of self-harm are well-established independent risk factors for inpatient suicide; however they lose their predictive value due to their high prevalence. Up to 70% of inpatients who committed suicide didn’t express suicidal ideation on the previous interviews. Most effective measures to prevent suicide are environmental modifications and staff education approaches, giving appropriate responses to each patient’s circumstances.
There is a paucity of literature on suicide in this setting. It should become a priority in national programs of Suicide Prevention.

Introduction
Bipolar disorder (BD) is a chronic and recurrent mental condition characterized by mood fluctuations between hypomania or mania and depression, with high level of burden and mortality rates (Hayes et al., 2015). Subsyndromal mood symptoms, including residual depression, mania and/or anxiety, are major risk factors for episodic relapses after mood stabilisation (Samalin et al., 2016). A psychological protective mechanism against the occurrence of these maladaptative mood symptoms is dispositional mindfulness (DM). DM refers to paying purposeful attention to present moment experiences with a curious, non-judgmental and accepting attitude (Radford et al., 2014). DM has been barely assessed in BD and there is very little evidence on the relationship between DM, residual mood symptoms and quality of life
ObjectivesTo explore associations between DM, residual mood symptoms and quality of life in individuals with BD
MethodsAfter informed consent, a total of 94 adults (Mean age= 45.57 years, 41.50% Male) with diagnosis of BD according to DSM-5 criteria, in full or partial remission,were recruited from the Bipolar and Depressive Disorders Unit at the Hospital Clinic of Barcelona. The ethical committee approved this study. Dispositional mindfulness was assessed using the Mindfulness Attention Awareness Scale (MAAS).The presence of residual depressive symptoms was assessed with the Hamilton Depression Rating Scale (HDRS), residual mania symptoms were assessed with the Young Mania Rating Scale(YMRS), and anxiety symptoms were assessed with the Hamilton Anxiety Rating Scale (HAM-A). The subjective quality of life was assessed with the Quality of Life in Bipolar Disorder Questionnaire (QoL-BD). Pearson correlations were carried out and the level of significance was set at p<0.05
ResultsDM was negatively related to residual depressive symptoms (r= -0.283; p=0.009) and to anxiety symptoms (r=-0.345; p<0.001), and positively related to quality of life (r=0.433; p<0.001), but not related to residual manic symptoms in BD
ConclusionsOur preliminary data suggest that BD patients with higher levels of DM may experience less depressive and anxiety subsyndromal symptoms and perceived higher quality of life. No associations were detected regarding mania symptoms. These findings support the use of mindfulness training as an adjunct therapy to pharmacotherapy to reduce residual mood symptoms and improve quality of life in patients with BD

Introduction
Anorexia nervosa (AN) is a severe psychiatric disorder that usually begins during adolescence and is associated with a high risk of mortality and morbidity, its treatment is complex and often ineffective. Psychiatric comorbidity is common in patients with eating disorders (with the prevalence of 20–95%), namely 39% in AN.
ObjectivesThe purpose of the authors is to review the most common areas of psychiatric comorbidity in AN, how it affects the course of both diseases and the potential treatment approaches.
MethodsA brief non-systematized review is presented, using the literature available on PubMed and Google Scholar.
ResultsThe most common psychiatric comorbidities in AN are: Affective disorders in 24-38% (mainly unipolar depression which can appear in up to 75% of patients, compared to 11% in bipolar disorder); Anxiety disorders in 25.5% (11% with panic disorder, 20% social phobia/social anxiety disorder, 15% specific phobias, 10% generalized anxiety disorder, 13% post-traumatic stress disorder); Obsessive compulsive disorder in 12%; Substance use disorders at 17%; Personality disorders around 30%. Other pathologies occur less commonly but can have a significant impact on the patient, namely Autism spectrum disorder (predictive factor for unfavourable outcome) or Schizophrenia (there are reports of reciprocal relationships between the two pathologies).
Some of these comorbidities may increase mortality in AN, namely unipolar depression, personality disorders, alcohol and illicit drug use.
The profound impact that starvation has on mood and cognition is well known. It can condition symptoms that are confused with other psychiatric diseases and change their clinical presentation. As such, the specific clinical characteristics and the therapeutic approach will be presented for each of the psychiatric comorbidities.
ConclusionsEarly diagnosis and treatment of psychiatric comorbidities in AN are essential to improve the prognosis of this eating disorder. The additional treatment of these pathologies will increase complexity of the already challenging treatment of AN, with the additional symptomatology often being perpetuated by an uncontrolled eating disorder and a poor compliance to treatment.
The limited evidence available for approaching these cases is based on the few studies available, most with insufficient samples.

We present the Cosmological Double Radio Active Galactic Nuclei (CosmoDRAGoN) project: a large suite of simulated AGN jets in cosmological environments. These environments sample the intra-cluster media of galaxy clusters that form in cosmological smooth particle hydrodynamics (SPH) simulations, which we then use as inputs for grid-based hydrodynamic simulations of radio jets. Initially conical jets are injected with a range of jet powers, speeds (both relativistic and non-relativistic), and opening angles; we follow their collimation and propagation on scales of tens to hundreds of kiloparsecs, and calculate spatially resolved synthetic radio spectra in post-processing. In this paper, we present a technical overview of the project, and key early science results from six representative simulations which produce radio sources with both core- (Fanaroff-Riley Type I) and edge-brightened (Fanaroff-Riley Type II) radio morphologies. Our simulations highlight the importance of accurate representation of both jets and environments for radio morphology, radio spectra, and feedback the jets provide to their surroundings.

Background:
Obesity is highly prevalent and disabling, especially in individuals with severe mental illness including bipolar disorders (BD). The brain is a target organ for both obesity and BD. Yet, we do not understand how cortical brain alterations in BD and obesity interact.
Methods:We obtained body mass index (BMI) and MRI-derived regional cortical thickness, surface area from 1231 BD and 1601 control individuals from 13 countries within the ENIGMA-BD Working Group. We jointly modeled the statistical effects of BD and BMI on brain structure using mixed effects and tested for interaction and mediation. We also investigated the impact of medications on the BMI-related associations.
Results:BMI and BD additively impacted the structure of many of the same brain regions. Both BMI and BD were negatively associated with cortical thickness, but not surface area. In most regions the number of jointly used psychiatric medication classes remained associated with lower cortical thickness when controlling for BMI. In a single region, fusiform gyrus, about a third of the negative association between number of jointly used psychiatric medications and cortical thickness was mediated by association between the number of medications and higher BMI.
Conclusions:We confirmed consistent associations between higher BMI and lower cortical thickness, but not surface area, across the cerebral mantle, in regions which were also associated with BD. Higher BMI in people with BD indicated more pronounced brain alterations. BMI is important for understanding the neuroanatomical changes in BD and the effects of psychiatric medications on the brain.

Background
Major depressive disorder (MDD) is a complex disorder with a significant public health burden. Depression remission is often associated with weight gain, a major risk factor for metabolic syndrome (MetS). The primary objective of our study was to assess prospectively the impact of response to antidepressant treatment on developing MetS in a sample of MDD patients with a current major depressive episode (MDE) and who are newly initiating their treatment.
MethodsIn the 6-month prospective METADAP cohort, non-overweight patients, body mass index <25 kg/m2, with MDD and a current MDE were assessed for treatment response after 3 months of treatment, and incidence of MetS after 3 and 6 months of treatment. Outcome variables were MetS, number of MetS criteria, and each MetS criterion (high waist circumference, high blood pressure, high triglyceridemia, low high-density lipoprotein-cholesterolemia, and high fasting plasma glucose).
ResultsIn total, 98/169 patients (58%) responded to treatment after 3 months. A total of 2.7% (1/38) developed MetS out of which 12.7% (10/79) (p value < 0.001) had responded to treatment after 3 months. The fixed-effect regression models showed that those who responded to treatment after 3 months of follow-up had an 8.6 times higher odds of developing MetS (odds ratio = 8.58, 95% confidence interval 3.89–18.93, p value < 0.001).
ConclusionCompared to non-responders, non-overweight patients who responded to treatment after 3 months of antidepressant treatment had a significantly higher risk of developing MetS during the 6 months of treatment. Psychiatrists and nurses should closely monitor the metabolic profile of their patients, especially those who respond to treatment.

The objective of this study was to evaluate the effects of growth-regulating insecticides of synthetic (e.g., Certero 480 SC, Intrepid 240 SC, Match EC and Mimic 240 SC) and botanical origins (e.g., Azamax 1.2 EC, Agroneem 850 EC, Azact 2.4 EC and Fitoneem 850 EC) on the biological parameters and fertility life table of Spodoptera frugiperda (J.E. Smith) under laboratory conditions. Larvae were fed insecticides that were incorporated into artificial diets. To develop the fertility life table, the following biological parameters were evaluated: survival at 7 days after infestation (d.a.i) and survivorship at adult eclosion, duration of the neonate-to-adult eclosion period, larval and pupal weights and total fecundity (number of total eggs per female). The results indicated that S. frugiperda neonates surviving LC25 or LC50 concentrations of the evaluated insecticides showed longer larval and egg-to-adult periods, lower larval and pupal weights and reduced fecundity, when compared to the control treatment. Larvae exposed to Azamax at LC25 or LC50 concentrations showed the greatest increase in generation duration (75 d). In addition, S. frugiperda adults emerged from pupae when larvae reared on an artificial diet containing growth regulating insecticides of synthetic and botanical origins produced fewer females per female per generation (Ro). As well as, lower rates of natural population increase per day (rm) compared to insects fed the control diet. Our findings indicated that, neem-derived products and growth-regulating insecticides of synthetic origin may be employed within integrated management strategies that aim to keep populations of S. frugiperda below levels that cause economic damage. Similarly, they offer alternatives for insecticide resistance management programs.
