The effect of ageing of adults of Echinostoma friedi (Trematoda: Echinostomatidae) on the infectivity of miracidia yielded was analysed. Miracidia were obtained after hatching of eggs obtained from adult worms of E. friedi collected weekly during the course of experimental infections in golden hamsters. Miracidial infectivity, measured in terms of percentage of infection in Lymnaea peregra, was significantly influenced by the age of the adult worms from which the miracidia were derived. Infective miracidia only were obtained from adult worms in the age range from 4 to 9 weeks post-infection. Infectivity was maximal in those miracidia derived from adults collected 8 and 9 weeks post-infection. The results suggest that adult worms producing viable eggs require additional maturation to be able to yield eggs containing infective miracidia.

Objective:
A commonly used confrontation naming task used in the United States is The Boston Naming Test (BNT). Performance differences has been found in Caucasian and ethnic minorities on the BNT. The Cordoba Naming Test (CNT) is a 30-item confrontation naming task developed in Argentina. Past research has shown acculturation levels can influence cognitive performance. Furthermore, one study evaluated geriatric gender differences on CNT performance in Spanish. Researchers reported that older male participants outperformed female participants on the CNT. To our knowledge, researchers have not evaluated ethnic differences on the CNT using a geriatric sample. The purpose of the present study was to examined CNT performance and acculturation in a Latinx and Caucasian geriatric sample. It was predicted the Caucasian group would outperform the Latinx group on the CNT. Moreover, the Caucasian group would report higher acculturation levels on the Abbreviated Multidimensional Acculturation Scale (AMAS) compared to the Latinx group.
Participants and Methods:The sample consisted of 9 Latinx and 11 Caucasian participants with a mean age of 66.80 (SD =6.10), with an average of 14.30 (SD = 2.00) years of education. All participants were neurologically and psychologically healthy and completed the CNT and the AMAS in English. Acculturation was measured via the AMAS English subscales (i.e., English Language, United States. Identity, United States, Competency). A series of ANCOVAs, controlling for years of education completed and gender, was used to evaluate CNT performance and acculturation.
Results:The ethnic groups were not well demographically matched (i.e., years of education and gender).We found that the Caucasian group outperformed the Latinx group on CNT performance p = .012, ηp 2 = .34. Furthermore, the Caucasian group reported higher acculturation levels (i.e., English Language, United States, Identity, United States, Competency) compared to the Latinx group p’s < .05, ηps2 = .42-.64.
Conclusions:To our knowledge, this is the first study to evaluate CNT performance between ethnic groups with a geriatric sample. As expected the Caucasian group outperformed the Latinx group on the CNT. Also, as expected the Caucasian group reported higher English acculturation levels compared to the Latinx group. Our findings are consistent with past studies showing ethnic differences on confrontational naming performance (i.e., The Boston Naming Test), favoring Caucasians. A possible explanation for group differences could have been linguistic factors (e.g., speaking multiple languages) in our Latinx group. Therefore, since our Latinx group reported lower levels of English Language, United States identity, and United States competency the Latinx group assimilation towards United States culture might of influence their CNT performance. Future studies with different ethnic groups (e.g., African-Americans) and a larger sample size should examine if ethnic differences continue to cross-validate in a geriatric sample.

Objective:
A 30-item confrontation naming test was developed in Argentina for Spanish speakers, The Cordoba Naming Test (CNT). The Boston Naming Test is an established confrontation naming task in the United States. Researchers have used the Boston Naming Test to identify individuals with different clinical pathologies (e.g., Alzheimer’s disease). The current literature on how Spanish speakers across various countries perform on confrontational naming tasks is limited. To our knowledge, one study investigated CNT performance across three Spanish-speaking countries (i.e., Argentina, Mexico, and Guatemala). Investigators found that the Guatemalan group underperformed on the CNT compared to the Argentine and Mexican groups. The purpose of this study was to extend the current literature and investigate CNT performance across five Spanish-speaking countries (i.e., Argentina, Mexico, Guatemala, Colombia, United States). We predicted that the Argentine group would outperform the other Spanish-speaking countries.
Participants and Methods:The present study sample consisted of 502 neurologically and psychologically healthy participants with a mean age of 29.06 (SD = 13.41) with 14.75 years of education completed (SD = 3.01). Participants were divided into five different groups based on their country of birth and current country residency (i.e., United States, Mexico, Guatemala, Argentina, & Colombia). All participants consented to voluntary participation and completed the CNT and a comprehensive background questionnaire in Spanish. The CNT consisted of 30 black and white line drawings, ranging from easy to hard in difficulty. An ANCOVA, controlling for gender, education, and age, was used to evaluate CNT performance between the five Spanish-speaking country groups. Meanwhile, a Bonferroni post-hoc test was utilized to evaluate the significant differences between Spanish-speaking groups. We used a threshold of p < .05 for statistical significance.
Results:Results revealed significant group differences between the five Spanish speaking groups on the CNT, p = .000, np2 = .48. Bonferroni post-hoc test revealed that the United States group significantly underperformed on the CNT compared to all the Spanish-speaking groups. Next, we found the Guatemalan group underperformed on the CNT compared to the Argentinian, Mexican, and Colombian groups. Additionally, we found the Argentinian group outperformed the Mexican, Guatemalan, and United States groups on the CNT. No significant differences were found between the Argentinian group and Colombian group or the Mexican group and Colombian group on the CNT.
Conclusions:As predicted, the Argentinian group outperformed all the Spanish-speaking groups on the CNT except the Colombian group. Additionally, we found that the United States group underperformed on the CNT compared to all the Spanish-speaking groups. A possible explanation is that Spanish is not the official language in the United States compared to the rest of the Spanish-speaking groups. Meanwhile, a possible reason why the Argentinian and Colombian groups demonstrated better CNT performances might have been that it was less culturally sensitive than the United States, Mexican, and Guatemalan groups. Further analysis is needed with bigger sample sizes across other Spanish-speaking countries (e.g., Costa Rica, Chile) to evaluate what variables, if any, are influencing CNT performance.

Introduction
Forced medication is one of the most frequently used coercive measures in acute mental health units. It is a practice that can lead to physical, psychological and psychopathological consequences. Therefore, it is necessary to implement measures to reduce its use. In this sense, it is interesting to study the variables that can be associated with its use, and thus take measures accordingly.
ObjectivesThis study attempts to identify the number of forced medication episodes between July 2017 and December 2018 treated in the catchment area of the Mental Health Service at Jerez Hospital. As a secondary objective, it pursues to identify the factors that conducted to the use of forced medication with the intention of being able to reduce the use of these measures.
MethodsA descriptive and retrospective study has been developed reviewing the total number of episodes of forced medication. Patients admitted and discharged from hospital between July 2017 and December 2018 treated in the Mental Health Service at Jerez Hospital. Data were extracted from medical records.
ResultsThe total number of episodes of forced medication identified was 330. In these episodes, the average age was 41 years, with a predominance of 74% of the male gender. The most used route in the episodes was intramuscular (94.8%), in addition, more than 50% needed the association of two drugs, the most used were haloperidol and olanzapine. The 32.7% of the episodes also required the use of mechanical restraint and 44.2% required the presence of security service.
Image:
ConclusionsWe present the descriptive analysis of a further study currently been conducted in hour hospital which means to stablish predictive factors for the use of forced medication. We therefore intend to create patient profile, as well as new measures specifically directed to these factors with which to diminish the use of forced medication.

Introduction
Almost nine months after the start of the war between Russia and Ukraine, millions of people have been affected physically, economically and mainly mentally. Those who have stayed in their homeland, and the ones that have chosen to emigrate to a safer place.
ObjectivesThe objective of this article is to assess the importance of social stressors in the onset of a brief psychotic episode, even in the absence of substance abuse or previous illnesses.
MethodsThe case of a 45-year-old woman is described, known by the Pediatric Emergency Service, for being the tutor of a patient who suffered from anxiety attacks, having emigrated without her parents from Ukraine together with her 5 brothers. The psychotic episode begins when our patient gets notified that she must abandon the custody of the girl, because she will have to go to Turkey with her legal guardians. The family explains the behavioral changes that the patient made and how the clinical picture worsened.
ResultsShe was admitted at the Hospital’s Psychiatry Service and antipsychotics treatment started. After 5 days, the episode had completely been solved.
ConclusionsIn conclusion, we highlight the importance of social problems in the development of a psychiatric pathology and the necessary elements to prevent it: family support network, fast and efficient care services and availability of hospital and pharmaceutical resources.

Introduction
Steroids are a necessary treatment for hypoxic respiratory failure; however there are many side effects that should be taken into account. A 44- year-old-woman with asthma and no past psychiatric history was admitted due to COVID-19 pneumonia and Respiratory syncytial virus (RSV) infection, presenting hypoxic respiratory failure. After two days of intravenous methylprednisolone administration, the patient presented acute psychosis and agitation.
It has been previously described that steroid use can cause effects such as mania, anxiety, agitation, delirium and psychosis amongst other. However they are a necessary treatment in respiratory illnesses and are sometimes unavoidable.
ObjectivesThe aim was to examine the appropriate medical response to steroid induced psychosis in patients with acute hypoxic failure.
MethodsA bibliographical review was done in PubMed database searching recent cases of steroid induced psychosis using the words (“Steroid”, “Psychosis” and “COVID-19”).
ResultsAccording to literature, it has been shown that partial or complete reduction of steroid use and/or use of psychotropic has been successfully used to treat steroid induced psychosis. Following the research it was decided to reduce intravenous methylprednisolone dose from 20mg/ 8h to 20mg/12h and start oral haloperidol 5mg/8h the first 24h and reducing the dose progressively as the patient recovered. After the first 24 hours the patient presented adequate response to steroids as well as partial response to antipsychotic treatment; presenting no further agitation, absence of hallucinations and partial persistence of the persecutory delusion. A couple of days later there was complete remission of the psychotic symptoms and the patient was on the way to recovery from COVID-19 and RSV.
ConclusionsThere is evidence that suggests that medications such as steroids used to treat COVID-19 and other respiratory illnesses can lead to psychotic episodes. It is very important to pay attention to possible side effects when treating with steroids and evaluate the patient history as well as suggest having a follow up visit after the hospital discharge.

Introduction
Multiple Sclerosis (MS) is an autoimmune inflammatory disease that affects 1 in 1000 people. Given the association of MS to many affective disorders and specifically with Bipolar Disorder (BD), it is possible that a manic episode and an acute episode of MS may appear together. In these cases, it is difficult to decide whether it is necessary to start a corticosteroid regimen as treatment for the acute episode of MS, since it may worsen manic symptoms.
ObjectivesThe aim is to carry out a review of the existing information in relation to the comorbidity prevalence of MS and TB as well as the joint treatment of both illnesses, and to expose the details of a clinical case, regarding the treatment that was used in the acute psychiatry unit.
MethodsFirst, a search was done in PubMed database reviewing recent cases of steroid induced psychosis using the words (Multiple Sclerosis) AND (Bipolar Disorder). Subsequently, we describe the case of a 41-year-old patient who was admitted to the acute care unit from the emergency department presenting manic symptoms (megalomania, sensation of increased capacities and ideas of mystical content) associated to episodes of muscle weakness and gait disturbances. A screening Magnetic Resonance was performed in which lesions with inflammatory-demyelinating characteristics were detected, and was therefore catalogued as MS debut.
ResultsAfter carrying out a bibliographical review, we can conclude that studies recommend the inclusion of MS within the differential diagnosis of a first manic episode (1), performing neurological examinations, complete anamnesis and imaging tests, given that there is a high prevalence ratio of the comorbidity (2.95%) (2). It has been described that the use of lithium has a calming and neuroprotective agent that may be useful (3).
ConclusionsWe consider it of interest to describe the therapeutic approach to the case. After the introduction of Aripiprazole and Lithium, a short regimen of methylprednisolone in high doses was administered to treat the MS episode. When the treatment started, the patient presented a progressive improvement of the manic episode and motor symptoms. We observed that corticosteroid therapy did not worsen the manic symptoms or the patient’s evolution in this case. We intend to contribute by providing information on the joint management of these pathologies and we consider that it is necessary to continue studying this matter to be able to manage these cases in the most appropriate way.

Introduction
Lithium associated with hypercalcemia may mimic a psychiatric condition and be confused for a relapse of bipolar disorder. The etiology seems to be due to a reduced sensitivity of the parathyroid cells to calcium, altering the parathyroid hormone (PTH) response. Lithium as an essential monovalent cation has some structural similarity to calcium (Ca) and can interact with protein receptors. This leads to changes in the inhibitory configuration of PTH and increased serum calcium concentrations, rising the threshold necessary to suppress hormone secretion.
Lithium-induced hyperparathyroidism (HIL) is the main cause of hypercalcemia in these patients.
ObjectivesBased on a clinical case of lithium-associated hypercalcemia in a patient with bipolar disorder, review the existing literature and state the needs for periodic monitoring protocols.
MethodsCase report and bibliographical review.
ResultsA 38-year-old woman, diagnosed with bipolar affective disorder at the age of 18, has been treated with lithium during which she developed secondary tubulointerstitial nephropathy as an adverse effect. Recently, she requested medical evaluation for constitutional syndrome associated with deterioration of general condition with loss of strength and difficulty in walking. Analytically, mild hypercalcemia was detected, and the study was extended to include Ca and PTH.
Chronic lithium therapy often develops mild hypercalcemia (approximately 10 to 20 percent of patients taking lithium), most likely due to increased secretion of PTH. Lithium can also unmask previously unrecognized mild hyperparathyroidism in patients with adenomas within a few years of starting therapy or induce parathyroid hyperplasia with a chronic use.
The hypercalcemia usually, but not always, subsides when the lithium is stopped. Normalization of serum calcium is more likely to occur one to four weeks post-lithium withdrawal in patients with a relatively short duration of lithium use. It is less likely in patients receiving lithium for more than 10 years.
Regarding the case to be presented, a review of the literature is carried out and the need to propose periodic calcium monitoring protocols is exposed.
ConclusionsRecommendations include determination of serum calcium every 6 months, urinary calcium and creatinine every 12 months, and bone mineral density monitoring every 1 to 3 years. Regular analytical monitoring including total calcium, PTH and vitamin D, would identify patients with a tendency to hypercalcemia so that appropriate measures could be taken. So as chronic treatment with lithium can develop mild hypercalcemia, I consider it necessary to develop periodic monitoring protocols for this adverse effect.

This systematic literature review aimed to provide an overview of the characteristics and methods used in studies applying the disability-adjusted life years (DALY) concept for infectious diseases within European Union (EU)/European Economic Area (EEA)/European Free Trade Association (EFTA) countries and the United Kingdom. Electronic databases and grey literature were searched for articles reporting the assessment of DALY and its components. We considered studies in which researchers performed DALY calculations using primary epidemiological data input sources. We screened 3053 studies of which 2948 were excluded and 105 studies met our inclusion criteria. Of these studies, 22 were multi-country and 83 were single-country studies, of which 46 were from the Netherlands. Food- and water-borne diseases were the most frequently studied infectious diseases. Between 2015 and 2022, the number of burden of infectious disease studies was 1.6 times higher compared to that published between 2000 and 2014. Almost all studies (97%) estimated DALYs based on the incidence- and pathogen-based approach and without social weighting functions; however, there was less methodological consensus with regards to the disability weights and life tables that were applied. The number of burden of infectious disease studies undertaken across Europe has increased over time. Development and use of guidelines will promote performing burden of infectious disease studies and facilitate comparability of the results.

Introduction
Chronic Hepatitis C infection is considered a systemic disease with extrahepatic manifestations, mainly neuropsychiatric symptoms, which is associated with a chronic low-grade inflammatory state. Hepatitis C virus (HCV) eradication is currently achieved in >98% of cases with oral direct-acting antivirals (DAA).
ObjectivesTo study potential clinical neuropsychiatric changes (mood, cognition, sleep, gastrointestinal, sickness, and motion) in HCV-infected patients after HCV eradication with DAA.
MethodsDesign: Cohort study. Subjects: 37 HCV-infected patients, aged<55 years old, with non-advanced liver disease receiving DAA; free of current mental disorder. 24 healthy controls were included at baseline. Assessment: -Baseline (BL) (socio-demographic and clinical variables, MINI-DSM-IV, and Neurotoxicity Scale (NRS), (mood, cognitive, sleep, gastrointestinal, sickness and motor dimensions). Follow-up: End-of-treatment, 12weeks-after and 48weeks-after DAA: NRS. Analysis: Descriptive and bivariate non-parametrical analysis.
ResultsNRS total score and dimensions where different between cases and controls (.000) at baseline. NRS total score (.000) and mood (.000), cognition (.000), sleep (.002), gastrointestinal (.017), and sickness (.003), except motor dimension score (.130) showed significant longitudinal improvement.
ConclusionsHCV-infected patients with mild liver disease presented significantly worse scores for neurotoxicity symptomatology in all dimensions compared to healthy individuals. After HCV eradication with DAA, both at short and long follow-up a significant improvement of the NRS total score and each of the dimensions (except motor) were observed. However, they did not reach the values of healthy individuals, suggesting a not complete neuropsychiatric restoration in the period studied.

Introduction
Alpha-pyrrolidinohexanophenone (α-PHP) is a synthetic cathinone with uneven distribution throughout the world. Its use is not uniformly regulated and its distribution is legal in some European countries. Easily accessible and available through different websites. Synthetic cathinones inhibit monoamine transporters which include dopamine, norepinephrine, and serotonin, resulting in increased neurotransmitter synaptic concentration. Ways of administration show wide range regarding latency period. Onset and appearance of symptoms as well as their duration and intensity may fluctuate. A decreasing order of latency (oral, inhaled, sublingual and intravenous) has been reported. α-PHP can result in the appearance of psychiatric symptoms, include among others, intoxication with sensory perception disturbances and α-PHP -induced psychotic episodes.
ObjectivesThe aim of our study was to assess the epidemiology, clinical and legal features regarding Alpha-pyrrolidinohexanophenone (α-PHP).
MethodsReview the current bibliography to upgrade the existing knowledge. -Present assorted cases with diverse clinical features. All cases include variability through psychopathological interview, symptoms assessment and treatment response according to rating scales (PANSS, YMRS). -Evaluate different treatment administration ways during acute phase and after hospital discharge.
ResultsDifferences were observed after hospitalization in the response using diverse rating scales. We used antipsychotics to treat intoxication with sensory perception disturbances and α-PHP -induced psychotic episodes. α-PHP had a negative impact on the quality of life of the patients.
Conclusionsα-PHP is a synthetic cathinone with potential risk to mental health and life of users. It is mandatory to implement common legislation all through the European Union to prevent its use and possible implications on population’s mental health.

Introduction
Long-term COVID-19 effects has been recently described as persistent and prolonged symptoms after an acute and severe SARS-COV-2 (1). An important concern is that the sequelae of severe COVID-19 may suppose a substantial outpatient 's burden for the specialized services in reopening pandemic phase (2).
ObjectivesTo describe the frequency of mental health service use in COVID-19 hospitalized patients after discharge and to estimate the costs associated to the post- discharge consultations.
MethodsWe used a 1-year follow-up cohort of 1455 COVID-19 inpatients hospitalized in La Paz University Hospital of Madrid, Spain between March 16th and April 15th, 2020. Data were retrieved from Psychiatry Service (PS) electronic health records and we described the frequency of mental health reason for consultation. We used information published by the Madrid health Office to estimate the cost of initial and following appointments.
ResultsOur sample consisted of 1,455 patients admitted with a COVID-19 diagnosis between March 16th and April 15th, 2020, and then discharged. Roughly half of them were men (776, 53%), 238 (16%) had a prior history of mental health problems, and 44 (3%) died. 193 participants (13%) visited the mental health department after being discharged. The total cost was estimated in 103,581 USD, of which two-thirds corresponded to patients with prior history of mental health problems.
ConclusionsOur results indicate that the mental health burden of severe COVID-19 inpatient s after discharge was substantial during the first year of follow-up. This generate important economic impact to mental health providers and society at large.

The giant gypsum crystals of Naica cave have fascinated scientists since their discovery in 2000. Human activity has changed the microclimate inside the cave, making scientists wonder about the potential environmental impact on the crystals. Over the last 9 years, we have studied approximately 70 samples. This paper reports on the detailed chemical–structural characterization of the impurities present at the surface of these crystals and the experimental simulations of their potential deterioration patterns. Selected samples were studied by petrography, optical and electronic microscopy, and laboratory X-ray diffraction. 2D grazing incidence X-ray diffraction, X-ray μ-fluorescence, and X-ray μ-absorption near-edge structure were used to identify the impurities and their associated phases. These impurities were deposited during the latest stage of the gypsum crystal formation and have afterward evolved with the natural high humidity. The simulations of the behavior of the crystals in microclimatic chambers produced crystal dissolution by 1–4% weight fraction under high CO2 concentration and permanent fog, and gypsum phase dehydration under air and CO2 gaseous environment. Our work suggests that most surface impurities are of natural origin; the most significant anthropogenic damage on the crystals is the extraction of water from the caves.

Sexuality and emotional life are rarely focus on attention in people suffering from severe long-term mental diseases like schizophrenia and bipolar disorder.
Methods53 patients and 47 matched controls were studied using a new questionnaire (SEXSAM Scale) measuring relevance of sexual and emotional relationships in patients’ daily life. A specific Psychotropic-Related Sexual Dysfunction Questionnaire (PRSexDQ-SALSEX Montejo 2001-2008), Sexual Activity Assessment Scale modified from Kinsey (Montejo 2006) and the HONOS Scale measuring bio-psychosocial functioning were also applied.
ResultsSexuality (physic and emotional) was scored as high valuable and the main motivation for sexual activity was looking for love and fondness in both groups. No differences were found in the value of more affective behaviours such as kissing, caressing, hugging or massaging. Global satisfaction in sexual and emotional life was significantly superior in control group and linked to the higher frequency of sexual relations. Many patients suffered for sexual dysfunction related to the treatment use and many of then were dissatisfied with their sexual life. Just a few numbers of patients had regular sexual intercourses. Patients describe an improvement in the self-perception of mood, appetite, sleep, anxiety level, humour sense and self-esteem when they have sexual relations. Predominant sexual activity for patients was masturbation. Prostitution use was higher in patient group. All these findings are negatively influencing personal satisfaction and quality of life.
ConclusionRelevance of sexual and emotional life in patients is as high as in normal population. These patients are more concerned about affection and companionship than about physical pleasure.

Purpose:
Two common approaches to identify subgroups of patients with bipolar disorder are clustering methodology (mixture analysis) based on the age of onset, and a birth cohort analysis. This study investigates if a birth cohort effect will influence the results of clustering on the age of onset, using a large, international database.
Methods:The database includes 4037 patients with a diagnosis of bipolar I disorder, previously collected at 36 collection sites in 23 countries. Generalized estimating equations (GEE) were used to adjust the data for country median age, and in some models, birth cohort. Model-based clustering (mixture analysis) was then performed on the age of onset data using the residuals. Clinical variables in subgroups were compared.
Results:There was a strong birth cohort effect. Without adjusting for the birth cohort, three subgroups were found by clustering. After adjusting for the birth cohort or when considering only those born after 1959, two subgroups were found. With results of either two or three subgroups, the youngest subgroup was more likely to have a family history of mood disorders and a first episode with depressed polarity. However, without adjusting for birth cohort (three subgroups), family history and polarity of the first episode could not be distinguished between the middle and oldest subgroups.
Conclusion:These results using international data confirm prior findings using single country data, that there are subgroups of bipolar I disorder based on the age of onset, and that there is a birth cohort effect. Including the birth cohort adjustment altered the number and characteristics of subgroups detected when clustering by age of onset. Further investigation is needed to determine if combining both approaches will identify subgroups that are more useful for research.

Introduction:
The cognitive processes are rather relevant in order to achieve a comprehensive and integrative recovery in schizophrenia and other psychosis.
Aim:To research the different variables implied in cognitive outcomes in psychosis in order to increase our knowledge to establish therapeutic interventions in this field.
Methods:An overall of 73 patients were included in the study. We used the SCIP and STROOP tests to measure the cognitive processes. We applied a comprehensive questionnaire for clinical and epidemiological variables including PANSS, SGPTS, GAF and SIX. After that, we constructed a binary logistic regression model with the following variables: positive, negative and general psychopathology PANSS subscales, PANSS subtype, first or second generation antipsychotic, stimulant drugs use, tobacco use, sex, age, onset age, number of psychotic episodes, global functioning and family history.
Results:Having more than two family members affected by any psychiatric disease was associated to a lesser outcomes in short-term and immediate memory. Likewise higher scoring in positive subscale PANSS was also associated to a worse performance in short-term and long-term memory, so stimulant drugs use was also related to a lesser immediate memory and working memory. Finally, a better global functioning appeared as a factor related to a better overall learning.
Conclusions:Our data show that a heavy genetic factor exists as a variable influencing cognitive performance. Moreover, stimulant drugs use and positive symptoms are another variables which can be controlled in order to improve cognitive performance.

Introduction.
The In-patient units are very closed and highly controlled healthcare resource and then patients have to join the community rapidly, and in sometimes feeling unprotected and with their needs non covered. We created a transition unit with a program of psychotherapeutic intervention, to offer an adequate transition between the acute episode and the incorporation to the community.
Objective.We describe the characteristics of the psychotherapeutic group, the aims and the results of the interventions.
Methods.Psychotherapeutic transition unit was created to offer intensive attention and control demand that is not possible to control in the community. The objects are to prevent re-admissions and relapse because of abandonment of treatment in patient with personality disorder and suicide attempts, and first episode, affective or psychotic. Patients are selected from the in-patients unit with inclusion criteria, and start going from the unit before discharge. The intervention is once per week, with a duration between 60–90 minutes. There is not a number of sessions, and we have approximately 10 patients per sessions.
Results.Since the beginning of the psychotherapeutic interventions, re-admissions have been decreased in patients with diagnosis of personality disorder (most histrionic and borderline disorder) with multiple admissions because of suicide attempt, some had been discharged. In another group of patient we have prevented relapses.
Conclusions.Psychotherapeutic interventions will be effective in patients with high risk of re-admissions and relapses. It is early to have solid conclusions, but the preliminary results encourage the continuation of the program.

The disease caused by the influenza virus is a global public health problem due to its high rates of morbidity and mortality. Thus, analysis of the information generated by epidemiological surveillance systems has vital importance for health decision making. A retrospective analysis was performed using data generated by the four molecular diagnostic laboratories of the Mexican Social Security Institute between 2010 and 2016. Demographics, influenza positivity, seasonality, treatment choices and vaccination status analyses were performed for the vaccine according to its composition for each season. In all cases, both the different influenza subtypes and different age groups were considered separately. The circulation of A/H1N1pdm09 (48.7%), influenza A/H3N2 (21.1%), influenza B (12.6%), influenza A not subtyped (11%) and influenza A/H1N1 (6.6%) exhibited well-defined annual seasonality between November and March, and there were significant increases in the number of cases every 2 years. An inadequate use of oseltamivir was determined in 38% of cases, and the vaccination status in general varied between 12.1 and 18.5% depending on the season. Our results provide current information about influenza in Mexico and demonstrate the need to update both operational case definitions and medical practice guidelines to reduce the inappropriate use of antibiotics and antivirals.

The continual rise of anthropogenic disturbance of ecosystems has been associated with an increasing incidence of emerging diseases. The largest amount of data on emerging diseases relates to bacterial and viral pathogens, but there is a lack of parasite data, especially from wildlife. Monitoring wildlife parasitic diseases should be considered a priority, especially in high biodiversity regions with strong anthropogenic impacts, like Mexico, where the wildlife/livestock/human interface is associated with increased risk of disease transmission. Mexico belongs to the top-ten megadiverse countries and is located between two biogeographic regions. This situation makes Mexico a favourable region for the spillover of animal pathogens to human beings, causing pandemics, such as the one recently caused by influenza virus A (H1N1). The current state of knowledge of Mexican wildlife parasites is scarce and focuses mainly in Neotropical fauna. Moreover, this knowledge is heterogeneous for different parasite groups, especially concerning their pathologic effects and epidemiology. The goals of this review are to compile information on Mexican wildlife parasites and to identify knowledge gaps in order to stimulate research on pending epidemiological, public health, ecological and pathological areas, and to encourage the creation of more specialized groups from the perspective of the One-Health concept.

I deficiency is still a worldwide public health problem, with children being especially vulnerable. No nationwide study had been conducted to assess the I status of Spanish children, and thus an observational, multicentre and cross-sectional study was conducted in Spain to assess the I status and thyroid function in schoolchildren aged 6–7 years. The median urinary I (UI) and thyroid-stimulating hormone (TSH) levels in whole blood were used to assess the I status and thyroid function, respectively. A FFQ was used to determine the consumption of I-rich foods. A total of 1981 schoolchildren (52 % male) were included. The median UI was 173 μg/l, and 17·9 % of children showed UI<100 μg/l. The median UI was higher in males (180·8 v. 153·6 μg/l; P<0·001). Iodised salt (IS) intake at home was 69·8 %. IS consumption and intakes of ≥2 glasses of milk or 1 cup of yogurt/d were associated with significantly higher median UI. Median TSH was 0·90 mU/l and was higher in females (0·98 v. 0·83; P<0·001). In total, 0·5 % of children had known hypothyroidism (derived from the questionnaire) and 7·6 % had TSH levels above reference values. Median TSH was higher in schoolchildren with family history of hypothyroidism. I intake was adequate in Spanish schoolchildren. However, no correlation was found between TSH and median UI in any geographical area. The prevalence of TSH above reference values was high and its association with thyroid autoimmunity should be determined. Further assessment of thyroid autoimmunity in Spanish schoolchildren is desirable.
