The order-disorder behavior of the isomorphous cation substitution of the octahedral sheet of phyllosilicates was investigated by Monte Carlo simulations based only on atomistic models in some three-species systems Al/Fe/Mg including a wide range of different octahedral compositions that can be relevant to clay compositions found in nature, especially for smectites and illites. In many cases, phase transitions do not occur, in that long-range order is not attained, but most systems exhibit short-range order at low temperature. The ordering of the octahedral cations is highly dependent on the cation composition. Variations in the tetrahedral charge (smectite vs. illite) produce slight differences in the cation distribution and the short-range and long-range order of octahedral cations do not change drastically. The average size of Fe clusters and the long-range order of Fe are not larger in illites than in smectites as previous reports concluded, but the proportion of Fe3+ cations non-clustered is higher in smectites than in illites. This behavior supports the experimental behavior of the Fe effect on the Al-NMR signal, which is lower in illites than in smectites.

Background:
Peri-diagnostic vaccination contemporaneous with SARS-CoV-2 infection might boost antiviral immunity and improve patient outcomes. We investigated, among previously unvaccinated patients, whether vaccination (with the Pfizer, Moderna, or J&J vaccines) during the week before or after a positive COVID-19 test was associated with altered 30-day patient outcomes.
Methods:Using a deidentified longitudinal EHR repository, we selected all previously unvaccinated adults who initially tested positive for SARS-CoV-2 between December 11, 2020 (the date of vaccine emergency use approval) and December 19, 2021. We assessed whether vaccination between days –7 and +7 of a positive test affected outcomes. The primary measure was progression to a more severe disease outcome within 30 days of diagnosis using the following hierarchy: hospitalization, intensive care, or death.
Results:Among 60,031 hospitalized patients, 543 (0.91%) were initially vaccinated at the time of diagnosis and 59,488 (99.09%) remained unvaccinated during the period of interest. Among 316,337 nonhospitalized patients, 2,844 (0.90%) were initially vaccinated and 313,493 (99.1%) remained unvaccinated. In both analyses, individuals receiving vaccines were older, more often located in the northeast, more commonly insured by Medicare, and more burdened by comorbidities. Among previously unvaccinated patients, there was no association between receiving an initial vaccine dose between days −7 and +7 of diagnosis and progression to more severe disease within 30 days compared to patients who did not receive vaccines.
Conclusions:Immunization during acute SARS-CoV-2 infection does not appear associated with clinical progression during the acute infectious period.

Introduction
The elderly represents the fastest growing group of the population. It is fair to assume that the portion of old age patients suffering from bipolar disorder will grow in a similar manner. Elderly patients represent approximately 25% of the bipolar population. Summarizing, 5–10% of patients were 50 years of age when they experienced their first manic episode, constituting the subgroup of late onset bipolar disorder (LOBD).
ObjectivesThe purpose of this case report and literature review is to emphasise the importance of LOBD in old population and to highlight its still sparse-knowledge.
MethodsDescriptive case study and review of literature (Arnold,I. et al. Old Age Bipolar Disorder—Epidemiology, Aetiology and Treatment. Medicina 2021,57,587; Baldessarini et al. Onset-age of bipolar disorders at six international sites. J Affect Disord 2010;121(1-2):143-6).
ResultsA 60-year-old woman is brought to the emergency department for evaluation by her family. Over the past 7 days, the patient has become increasingly irritable and argumentative, is sleeping less, is talking faster than usual and has begun to express paranoid concerns about her students “stealing my exam”. The patient is a university professor.
In the assessment interview she is hyperverbal, expansive, and grandiose. The family has also just recently discovered that she has spent a large sum of money on the Internet.
She has no history of psychiatric contact or substance use disorders; however, she has a family history of severe depression.
In the absence of any plausible non-psychiatric condition that could mimic or induce mania, the working diagnosis is bipolar I disorder, most recent episode (MRE) manic with psychotic features.

ConclusionsThe share of older age bipolar disorder will grow constantly in the next decades and further research on this neglected patient group is urgently required.

Introduction
Women with bipolar disorder often ask their treating clinician for information about family planning, as they are concerned about the impact of their illness on offspring. Pregnancy places additional stress on patients, and physiological changes are particularly acute during postpartum. On the other hand, the risk of abnormalities and teratogenicity from psychotropic drugs is significant. The decision wether resuming or discontinuating lithium is discussed.
ObjectivesWe present a theoretical review on the topic.
MethodsA bibliographic review is presented.
ResultsThe choice to continue medication during pregnancy balances the risks of an untreated illness with the risks of medication exposure. Abrupt discontinuation of psychotropic medications is associated with an increased risk for illness recurrence. Women with BD who discontinue their medications before or during pregnancy have a 71% risk of recurrence with new episodes occurring most frequently in the first trimester. Recurrent illness during pregnancy is associated with a 66% increase in the risk of postpartum episodes. Untreated or under-treated BD during pregnancy is associated with poor birth outcomes independent of pharmacotherapy exposure, including preterm birth, low birth-weight, intrauterine growth retardation, small for gestational age, fetal distress, and adverse neurodeve- lopmental outcomes. Women with untreated BD also have behavioral risk factors such as decreased compliance with prenatal care, poor nutrition, and high-risk behaviors. Impaired capacity to function may result in loss of employment, health care benefits, and social support. The biological and psychosocial risks of a BD episode are the justification for the risk of medication exposure.
Fetal exposure to lithium has been associated with an increased risk for cardiac abnormalities. The risk for Ebstein’s anomaly with first trimester exposure is 1 (0.1%) to 2 in 1000 (0.2%), but the absolute risk remains low. Folate supplementation with 5 mg reduces the risk and severity of congenital heart disease. Lithium toxicity causes lethargy, hypotonia, tachycardia, coma, cyanosis, and chronic twitching in the newborn.
Strategies to minimize fetal exposure and maintain efficacy include using the lowest effective dose, prescribing lithium twice daily to avoid high peak serum concentrations, and regular monitoring of lithium serum concentrations. The effective serum concentration must be established before pregnancy. If a therapeutic concentration has not been established, the lithium dose is titrated to a concentration within the therapeutic range. Breast feeding is discouraged in women taking lithium because of the high rate of transmission to the infant.
ConclusionsTreatment decisions for pregnant women with mood disorders must weigh the potential for increased risks of lithium during pregnancy, especially during the first trimester, against its effectiveness at reducing relapse.

Introduction
The occurrence of psychotic symptoms induced by dopaminergic drugs marks a new phase in the course of Parkinson’s disease (PD). The term drug induced psychosis may be used when other significant psychiatric diseases are excluded in patients with no history of psychosis. The prevalence of dopaminomimetic psychosis varies from 5% to 20%. Therefore, knowledge of the psychopharmacological management of this condition is essential.
ObjectivesThe purpose of this case report and literature review is to to learn the psychopharmacological management of this not uncommon medical complication.
MethodsDescriptive case study and review of literature
ResultsWe present the case of a 71-year-old man with a medical history of Parkinson’s disease with partial response to treatment with high doses of levodopa and carbidopa.
He was brought to the emergency department by his family due to the presence of behavioural alterations at home.
The patient reported seeing men in foam trying to harm his family. In a disjointed way in his speech, he links this idea with the delusional belief that he is being watched by electronic devices placed throughout the house. In a variegated manner he links this with a coelotypical type of discourse, however the delusional ideation remains unstructured throughout.
With no previous personal or family history of mental health and ruling out underlying organic conditions, a diagnosis of psychosis secondary to pharmacological treatment for Parkinson’s disease is presumed.
Considering the risks and benefits, it was decided to maintain the anti-Parkinson’s dose in order to avoid worsening the patient’s motor function. Therefore, after reviewing the literature, the best option was to introduce clozapine at low doses, up to 50 mg at night, with the respective analytical control. After a week’s admission, the patient began to improve psychopathologically, achieving an ad integrum resolution of the psychotic symptoms.
ConclusionsDespite the availability of other antipsychotic treatments such as quetiapine or the more recent pimavanserin, clozapine remains the treatment of choice for drug-induced psychosis in Parkinson’s disease.

Introduction
The Positive and Negative Syndrome Scale for Schizophrenia Autism Severity Scale (PAUSS) scale can be derived from the Positive and Negative Schizophrenia Syndrome Scale, enabling an assessment of psychotic and autistic dimensions with a single tool.
ObjectivesThe aim of the study was to investigate the prevalence of autistic traits and the diagnostic, developmental, clinical, and functional correlates of this phenotype in a sample of early-onset psychosis (onset before age 18 years; EOP).
MethodsProspective observational 2 year- follow-up study in a sample of young people with a first-episode of EOP. Demographic, perinatal, developmental, cognitive, clinical, and functional data were collected. PAUSS total scores and socio-communication and repetitive behaviors subscores were calculated. We used the proposed cut-off points for adult populations to define prevalence of autistic traits (PAUSS≥30). Subgroups of patients with and without autistic traits were identified based on the total PAUSS terciles. We used the Cronbach’s alpha test to assess the PAUSS internal consistency. Linear mixed models were performed to compare changes in PAUSS during follow-up between diagnostic subgroups [i.e., non-affective psychosis (including schizophrenia and schizophreniform disorder), affective psychosis (including bipolar disorder, schizoaffective disorder and major depressive disorder with psychotic features), and other psychosis (including brief psychotic disorder and psychosis not otherwise specified)]. Developmental, clinical, and functional variables were compared between subgroups with and without autistic traits with logistic regression analysis.
Results248 patients with PIT were included (age 15.69 ± 1.86 years, 38.65% female). The prevalence of autistic traits in EOP was 7.04%, with significantly higher prevalence in the group of patients with non-affective psychosis (15.20%) than in other diagnostic groups. PAUSS scores significantly decreased over time, with no significant differences in the trajectories of the total PAUSS and its subscores among the three diagnostic subgroups during the 2-year follow-up. The PAUSS showed good internal consistency at all visits (Cronbach’s alpha > 0,88). Patients with autistic traits presented longer duration of untreated psychosis, longer duration of the first inpatient admission, poorer social adjustment in childhood, poorer functionality, greater clinical severity, and poorer response to treatment during follow-up than patients without autistic traits.
ConclusionsThe PAUSS is an easy-to-apply tool that can be useful to differentiate psychosis subgroups with worse prognosis.

Introduction
Denial of pregnancy is the phenomenon where a woman fails to recognize or accept her pregnancy at >20 weeks gestational age. It associates with increased morbidity and mortality of mother and child, and can be classified as non-psychotic or psychotic. There is fewer medical literature regarding the latter, making it difficult to recognize, let alone to treat, since we do not have robust data regarding incidence nor approved interventions or treatment.
ObjectivesTo describe this unfamiliar entity in order to be able to perform a proper diagnosis and thus prevent possible negative outcomes.
MethodsWe present a case report alongside a narrative literature review on the topic.
ResultsWe report the case of a 39-year-old caucasian woman, foreign, undomiciled, with an advanced pregnancy, who was admitted to a Psychiatry in-patient unit due to psychotic symptoms such as mistrust and delusions. She showed scarce collaboration during assessment and did not give any plausible information about her identity. Her birthplace and prior medical records were therefore unknown. Apparently, she had no family nor social support network. Despite the obvious signs, she did not recognize being pregnant and showed great irritability when asked; her responses ranged from claiming she was suffering from a gastric tumor and making delusional attributions of symptoms clearly related to the pregnancy to partially acknowledging her state but refusing to answer any questions on the matter. Blood work showed no significant abnormalities and obstetric ultrasound revealed a low risk 35 weeks pregnancy.
With an estimated prevalence of 1:475 in general population, denial of pregnancy is not as rare as it may seem. The psychotic variant, however, is rather uncommon. Typically, women with psychotic pregnancy denial have prior history of major mental illness, most frequently schizophrenia, and suffer from extreme psychosocial vulnerability. They usually present previous or anticipated child custody loss, which hampers the process of developing antenatal attachment behaviours. Psychotic denial does not associate with concealing, since these women are mentally detached from the gestation and tend to create delusional explanations to their pregnancy symptoms. Not all of them show complete denial, some being able to acknowledge it, though mostly in an inconsistent way. These patients often fail to seek prenatal care or are noncompliant, they are at greater risk of drug exposure, and some are unable to recognize symptoms of labour, all of which increases the rate of negative outcomes for mother and baby, including neonaticide.
ConclusionsPsychotic denial is a rare diagnosis which should be properly assessed due to its clinical implications and the need to prevent potential negative outcomes for mother and baby.

Introduction
Anorexia nervosa is a behavioral mental disorder, characterized by body dysmorphia, an intense fear of gaining weight and behaviors that interfere with this, in addition to a restriction of food intake, associated usually with medical complications, even a considerable risk of death.
Several psychotherapeutic approaches have been used along last decades. Until relatively recently, parents have been recognized as part of the problem, but nowadays we involve them into the therapeutic process through family therapy based on a systemic approach, recommended in current published clinical guidelines and research findings, with consistent evidence, as the first-line treatment of patients with anorexia nervosa.
ObjectivesA case of a patient with anorexia nervosa, is presented followed by a theoretical review on the topic.
MethodsA case is presented with a bibliographic review.
ResultsA 24-yeard-old female was hospitalized for renutrition due to a significant weight loss and multiple physical symptoms. After 4 months without progress, the patient was transferred to the psychiatric ward.
Once there, physical stabilisation was achieved with family therapy and pharmacological treatment, based on progressive administration of Clomipramine, previously assessed by Cardiology, which improved rumination and obsessive behaviour. We conduct daily individual and weekly family interviews, working on family dynamics, emotional regulation strategies and more adaptive ways of communication. Likewise, several lines of action were found in the systemic work: peripheral father; maternal over-involvement; fraternal rivalry; difficulties of interaction between all of them, derived from “the role of the sick person” and intra-family communication around the illness. Finally, showed effectiveness in terms of an improvement in interpersonal relationships, greater assertiveness and an optimistic attitude with an active search for coping strategies.
ConclusionsHistorically, parents have been recognized by a causal factor in the pathogenesis of this disorder. Nevertheless, the abolition of the emphasis on family responsibility, motivated by a philosophic and evidence-based, has allowed us to see them as an essential resource in aiding the patient in the improvement process. This parental involvement has resulted in a relevant reduction in morbidity, as well as a significant decrease treatment attrition rates. It has been noted a re-establishment in other individual and family factors such as self-esteem, quality of life, and some aspects of the experiences of caregiving, and behavioral symptoms have been resolved.

Introduction
More than 700,000 people die by suicide in 2019 globally (World Health Organitation 2021). Mental health problems constitute a risk factor for suicidal behavior and death by suicide (Hoertel et al. Mol Psychiatry 2015; 20 718–726). Different mental disorders have been related to different forms of suicidal ideation and behavior (Conejero et al. Curr Psychiatry Rep 2018; 20, 33) (Quevedo et al. Compr Psychiatry 2020; 102 152194). However, little is known on comorbidity profiles among suicide attempters.
ObjectivesThe aim of our work was to identify the psychiatric comorbidity profiles of individuals who were admitted a hospital emergency department due to a suicide attempt. Moreover, it intended to know their clinical characteristics according to comorbidity profile.
MethodsA sample of 683 attempters (71.30% female; M age= 40.85, SD= 15.48) from the SURVIVE study was used. Patients were assessed within the 15 days after emergency department admission. Sociodemographic (i.e., sex, age, marital status and employment status) and clinical data were collected. The International Neuropsychiatric Interview (MINI) was used to assess DSM-V Axis 1 mental health diagnoses and the Columbia Suicide Rating Scale (C-SSRS) to assess suicidal ideation and behavior. The Acquired Capacity for Suicide-Fear of Death Scale (ACSS-FAD), the Patient Health Questionnaire (PHQ-9) to assess the frequency of depressive symptoms during the past 2 weeks, and the General Anxiety Disorder-7 (GAD-7) scale to assess symptoms of worry and anxiety were also conducted. For the identification of comorbidity profiles, latent class analysis framework was followed considering diagnosis to each individual disorder as clustering variables. On the other hand, binary logistic regression was used to study the relationship between comorbidity profile membership and clinical factors.
ResultsTwo classes were found (Class I= mild symptomatology class, mainly featured by emotional disorder endorsement; and Class II= high comorbidity class, featured by a wide amount of endorsed diagnoses) (see figure 1). Individuals from the High comorbidity class were more likely to be female (OR= 0.98, p<.05), younger in age (OR= 0.52, p< .01), with more depressive symptoms (OR=1.09, p<.001) and have greater impulsivity (OR= 1.01, p<.05).

ConclusionsWe found two profiles of people with suicidal behavior based on the presence of mental disorders. Each of the suicidal subtypes had different associated risk factors. They also had a different profile of suicidal behavior.

Introduction
CD is characterized by at least three features: its duration is prolonged, it does not resolve spontaneously and it is rarely completely cured. Approximately 10-15% of young people have CD. Adolescents with CD often have emotional and behavioral problems.
ObjectivesTo assess risk factors, derived psychiatric pathologies and coping strategies for a CD diagnosis in adolescence.
MethodsAn extensive literature review was carried out on the subject in question, extracting information mainly from scientific articles, manuals and books.
ResultsThe main risk factors are those related with the CD in question, physical sequelae, the need for long-term hospital admissions or the use of drugs whose side effects include affective or behavioral symptoms; those related to the personality traits of the affected child or adolescent. In addition, as far as the family is concerned, the presence of a low level of education, lack of support or communication, as well as the presence of psychiatric disorders or serious medical conditions in parents. Among the most frequent psychiatric disorders associated with CD are affective and anxiety disorders, adaptive disorders, somatoform disorders, eating disorders and behavioral disorders. Whatever the CD is, it generates high levels of stress and uncertainty in the patient and family, which must be dealt together from a flexible perspective, allowing child or adolescent to adapt to the changes, reorganize and facing them with adaptive patterns of behavior. For this, it will be essential to have adequate social and family support with relational style based on communication, trust and acceptance.
ConclusionsIn general, both adolescents with CD and their families have an adequate capacity to adapt to the repercussions and effects derived from the disease. Nevertheless, in case of possible emotional difficulties that may appear, a comprehensive and individualized approach to these adolescents and their families is necessary to provide them resources and coping strategies in different areas and contexts in which the disease debuts.The comprehensive therapeutic approach will consist of interventions at the individual and family level. Among the main objectives of these interventions are to achieve acceptance and adaptation to CD provinding adequate psychosocial support to enable them to cope with CD in the best possible way and to detect and address the emotional implications, even coexisting psychopathology.

Introduction
Corticosteroids are drugs widely used in clinical practice for their anti-inflammatory and immunosuppressive properties. Despite their beneficial effects, a high association of these drugs with neuropsychiatric adverse effects such as psychosis, mania, depression, delirium or increased risk of suicide, among others, has been observed. We present the case of 54-year-old man who started treatment with hydroaltesone 20 mg/8h after undergoing surgery for a pituitary macroadenoma who began with maniform clinic.
ObjectivesTo know the prevalence, risk factors and treatment of mania as a side effect of corticosteroid drugs.
MethodsPresentation of the case and review of the available literature on the risk of developing mania after corticosteroid treatment.
ResultsSeveral studies confirm that the incidence of psychiatric adverse effects after the use of corticosteroids is around 6% if we refer to severe reactions; 28% moderate reactions; and 72% if we consider milder reactions. The direct relationship between these drugs and affective symptoms ranges in rates between 1-50% of cases, the most frequent being depression and mania. The risk of mania after treatment with corticosteroids is 4-5 times higher than if we compare it with a group of population not exposed to these drugs. There is a dose-response relationship, increasing the risk from a daily dose of 40 mg/day, with an average duration of symptoms of around 21 days. Female sex seems to be a risk factor in relation to the fact that diseases requiring this type of treatment are more common in this gender. As first-line treatment for mania secondary to corticosteroids, a decrease in treatment dose or its interruption, whenever possible, is proposed. Adjuvant treatment may be required, with atypical antipsychotics being the first choice.
ConclusionsCorticosteroid therapy has a direct dose-response relationship with the presence of psychiatric adverse effects such as mania. Dose and sex have been studied as possible adverse effects. Therefore, the pharmacological treatment of choice consists of a reduction in the dose of corticosteroids administered or withdrawal, if possible, and may be combined with an atypical antipsychotic such as olanzapine, quetiapine or risperidone. Re-evaluation is recommended until complete resolution of the clinical picture and then antipsychotic treatment can be progressively withdrawn.

Introduction
Wenicke-Korsakoff syndrome (WKS) is a neurological disorder caused by thiamine deficiency. Wernicke Encephalopathy (WE) is the acute phase and the chronic phase is called Korsakoff-syndrome (KS).
ObjectivesTo review the current literature on the management of WKS in a patient with anorexia nervosa.
MethodsWe report the case of a 63-year-old woman admitted to the Psychiatry Unit after weight loss in the last 3 months (from 39 kg to 33,500 kg). She only made one meal a day. By exploration and analysis, neoplastic disease is ruled out (thoraco-abdomino-pelvic CT without pathological findings). She has maintained restrictive intakes for more than 30 years. A long-term anorexia nervosa (AN) is suspected, with a worsening of restrictive behavior in recent months. Upon admission, she has a weight of 33,500 kg and a BMI of 14,10. She has a left palpebral ptosis and an alteration of the anterograde memory as well as affectation of executive functions. Progressive oral diet is started, and due to the suspicion of a WKS, thiamine ev is started for a week and then continued with oral thiamine. Thiamine levels are extracted once the ev treatment has begun, so we do not have previous levels to know if they were decreased. Brain MRI shows bilateral hyperintensities in white matter and at supratentorial level in T2 and FLAIR. After a month and a half of admission, the patient has progressively regained weight, has managed to make adequate intakes and has improvement in memory.
ResultsAn adverse consequence of severe malnutrition in AN due to severe food restriction and purging behavior is thiamine deficiency, and also global cerebral atrophy and concomitant cognitive deficits can be found. Thiamine deficiency occurs in 38% of individuals with AN and is often unrecognized. WKS is caused by thiamine deficiency, and WE is the acute phase of this syndrome (presentation of triad can vary). The chronic phase is KS and consists in amnesia with confabulations. WKS typically develops after malnourishment in alcoholic patients but can be associated in nonalcoholic such as prolonged intravenous feeding, hyperemesis, anorexia nervosa, refeeding after starvation, thyrotoxicosis, malabsorption syndromes; hemodialysis; peritoneal dialysis; AIDS; malignancy. WKS is a clinical diagnosis, and no specific abnormalities have been found in cerebrospinal fluid, brain imaging or electroencephalograms. MRI has a sensitivity of 53%, but high specificity of 93%, and shows an increased signal in T2 and FLAIR sequences, bilaterally symmetrical in the paraventricular regions of the thalamus, the hypothalamus, mamillary bodies, the periaquedutal region, the floor of the fourth ventricle and midline cerebellum.
ConclusionsIf the disorder is suspected, thiamine should be initiated immediately in order to prevent irreversible brain damage, with an estimated mortality rate of about 20%, or to the chronic form of the WE in up to 85% of survivors

Background
Tobacco is a highly prevalent substance of abuse in patients with psychosis. Previous studies have reported an association between tobacco use and schizophrenia. The aim of this study was to analyze the relationship between tobacco use and first-episode psychosis (FEP), age at onset of psychosis, and specific diagnosis of psychosis.
MethodsThe sample consisted of 1105 FEP patients and 1355 controls from the European Network of National Schizophrenia Networks Studying Gene–Environment Interactions (EU-GEI) study. We assessed substance use with the Tobacco and Alcohol Questionnaire and performed a series of regression analyses using case-control status, age of onset of psychosis, and diagnosis as outcomes and tobacco use and frequency of tobacco use as predictors. Analyses were adjusted for sociodemographic characteristics, alcohol, and cannabis use.
ResultsAfter controlling for cannabis use, FEP patients were 2.6 times more likely to use tobacco [p ⩽ 0.001; adjusted odds ratio (AOR) 2.6; 95% confidence interval (CI) [2.1–3.2]] and 1.7 times more likely to smoke 20 or more cigarettes a day (p = 0.003; AOR 1.7; 95% CI [1.2–2.4]) than controls. Tobacco use was associated with an earlier age at psychosis onset (β = −2.3; p ⩽ 0.001; 95% CI [−3.7 to −0.9]) and was 1.3 times more frequent in FEP patients with a diagnosis of schizophrenia than in other diagnoses of psychosis (AOR 1.3; 95% CI [1.0–1.8]); however, these results were no longer significant after controlling for cannabis use.
ConclusionsTobacco and heavy-tobacco use are associated with increased odds of FEP. These findings further support the relevance of tobacco prevention in young populations.

Haemosporidia (Apicomplexa, Haemosporida) are protozoa that infect vertebrate blood cells and are transmitted by vectors. Among vertebrates, birds possess the greatest diversity of haemosporidia, historically placed in 3 genera: Haemoproteus, Leucocytozoon and Plasmodium, the causative agent of avian malaria. In South America, existing data on haemosporidia are spatially and temporally dispersed, so increased surveillance is needed to improve the determination and diagnosis of these parasites. During the non-breeding season in 2020 and 2021, 60 common terns (Sterna hirundo) were captured and bled as part of ongoing research on the population health of migratory birds on the Argentinian Atlantic coast. Blood samples and blood smears were obtained. Fifty-eight samples were screened for Plasmodium, Haemoproteus and Leucocytozoon, as well as for Babesia parasites by nested polymerase chain reaction and by microscopic examination of smears. Two positive samples for Plasmodium were found. The cytochrome b lineages detected in the present study are found for the first time, and are close to Plasmodium lineages found in other bird orders. The low prevalence (3.6%) of haemoparasites found in this research was similar to those reported for previous studies on seabirds, including Charadriiformes. Our findings provide new information about the distribution and prevalence of haemosporidian parasites from charadriiforms in the southernmost part of South America, which remains understudied.

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.

Objectives:
The aim of this study was to investigate the psychometric properties of the Spanish version of the Stigma of Occupational Stress Scale for Doctors (SOSS-D) and the factors associated with Physician Burnout in Paraguay.
Methods:Participants included 747 Paraguayan healthcare workers, aged 24–77 years old, of both sexes. SOSS-D was translated into Spanish and validated through an exploratory and confirmatory factor analysis. Participants were also scored with the Oldenburg Burnout Inventory (OLBI), the CAGE questionnaire, and the stigma subscale of the Perceived Barriers to Psychological Treatment (PBPT) measure.
Results:Three factors had a raw eigenvalue greater than 1, and explained 61.7% of total variance. The confirmatory analysis confirmed that the scale is three-dimensional. The model adjustment was good, according to all fit indices. OLBI results indicate clinically significant disengagement in 85.9% and clinically significant exhaustion in 91.6% of participants. Of the 747 participants, 57.6% reported alcoholic beverage consumption and among those, 19.3% had problematic alcohol consumption according to the CAGE questionnaire. The correlation between SOSS-D and the stigma subscale of the PBPT was statistically significant (r = 0.245, p < 0.001).
Conclusions:The Spanish version of the SOSS-D was found to have good psychometric properties and adequately reproduces the three-dimensional model of the original English version.

Introduction
The extent to which structural gender inequality contributes to macro-level differences in postpartum depression (PPD) remains largely unknown.
ObjectivesTo examine the association of structural gender inequalities with national-level prevalence estimates of PPD symptoms.
MethodsMeta-analytically derived national-level estimates for the prevalence of PPD symptoms – based on the Edinburgh Postnatal Depression Scale (EPDS) – were combined with economic (e.g., income inequality), health (e.g., infant mortality rate), sociodemographic (e.g., urban population), and structural gender inequality variables (e.g., abortion policies) for 40 countries (276 primary studies). Data came from a prior meta-analysis on PPD prevalence and international agencies (e.g., UNICEF). Meta-regression techniques and traditional p-value based stepwise procedures, complemented with a Bayesian model averaging approach, were used for a robust selection of variables associated with national-level PPD symptom prevalence. Sensitivity analyses excluded primary studies with small sample sizes or countries lacking evidence for psychometric properties of the EPDS.
ResultsIncome inequality (β = 0.04, 95% CI = 0.02 to 0.07) and abortion policies (β = 0.02, 95% CI = 0.00 to 0.03) were the only variables included in the final, adjusted model, accounting for 60.7% of the variance in PPD symptoms across countries. Gradual liberalizations of abortion policies were associated with a 2% decrease in national-level PPD symptom prevalence. Results were robust to sensitivity analyses.
ConclusionsStructural gender inequalities might be social determinants of PPD, as the liberalization of abortion policies seem to impact women’s perinatal mental health on a population level. More research on structural gender inequality is needed to guide policy and practice.

Immune system aging, a process known as immunosenescence, involves a striking rearrangement affecting all immune cells, resulting in an increased rate of infections and a major incidence of autoimmune diseases and cancer. Nonetheless, differences in how individuals of the same chronological age carry out this immunosenescence establishment and thus the aging rate have been reported. In the context of neuroimmunoendocrine communication and its role in the response to stress situations, growing evidence suggests that social environments profoundly influence all physiological responses, especially those linked to immunity. Accordingly, negative contexts (loneliness in humans/social isolation in rodents) were associated with immune impairments and decreased lifespan. However, positive social environments have been correlated with adequate immunity and increased lifespan. Therefore, the social context in which an individual lives is proposed as a decisive modulator of the immunosenescence process and, consequently, of the rate of aging. In this review, the most important findings regarding how different social environments (negative and positive) modulate immunosenescence and therefore the aging rate, as well as the role of stress responses, hormesis, and resilience in these environments will be explained. Finally, several possible molecular mechanisms underlying the effects of negative and positive environments on immunosenescence will be suggested.
