Understanding the determinants of malnutrition is pivotal for public health interventions. This study aimed to identify socio-economic, demographic, dietary and maternal determinants of wasting and overweight among Brazilian children between 6 and 59 months. Data from the Brazilian National Survey on Child Nutrition were analysed (n 11 789). Children’s weight-for-height Z-scores were calculated according to the WHO growth standard and classified as wasting (Z < −2), normal weight (–2 ≤ Z ≤ 1), overweight risk (1 < Z ≤ 2) and overweight (Z > 2). Socio-economic, demographic, dietary and maternal covariables were considered. Adjusted multinomial logistic regression (OR and 95 % CI) was employed. The prevalence of overweight and wasting was 9·5 and 2·6 %, respectively. In the adjusted model, younger age (6–23 months: OR: 1·7; 95 % CI: 1·3, 2·2), consumption of ≥ 5 ultra-processed food groups (OR: 1·8; 95 % CI: 1·1, 3·1), maternal underweight (OR: 0·4; 95 % CI: 0·2, 0·9), overweight (OR: 1·5; 95 % CI: 1·2, 1·9) and mild food insecurity (OR: 0·8; 95 % CI: 0·6, 1·0) were associated with child overweight. The Brazilian Northeast (OR: 4·9; 95 % CI: 2·1, 11·3), Southeast (OR: 7·1; 95 % CI: 3·0, 16·6), South (OR: 4·7; 95 % CI: 1·8, 12·1), Midwest regions (OR: 2·7; 95 % CI: 1·2, 6·2) and maternal underweight (OR: 5·4; 95 % CI: 2·7, 10·7) were associated with wasting. Overweight in Brazil is prevalent among children between 6 and 59 months, while wasting is not a major public health problem. The main determinants of these Brazilian children’s nutritional status were age, ultra-processed food consumption and maternal nutritional status.
This study evaluated the effects of capsaicin (CAP) supplementation on the intake, nutrient digestibility, ruminal fermentation, nitrogen balance, microbial protein synthesis and health traits of bulls managed on pasture. Eight crossbred (Holstein x Zebu) cattle averaging 313 ± 31 kg of body weight (BW) were arranged in a replicated 4 × 4 Latin square design (one square of four bulls, rumen fistulated with 4-inch silicone cannulas and one square of four non-fistulated bulls), which were kept on Pangola grass pasture (Digitaria decumbens). Each experimental period consisted of 21 days, with 7 days for data collection (no washout between periods). Bulls were randomly assigned to the following treatments: CON (control): concentrate supplementation at 0.5% live weight (BW) and no additive (CAPCIN®), or concentrate supplementation at 0.5% BW in association with CAPCIN® (NutriQuest, Campinas, Brazil) fed at the inclusion rates of 150 (CAP150), 300 (CAP300) and 450 (CAP450) mg/animal/day. Digestibilities of dry matter, organic matter and neutral detergent fibre showed quadratic responses to CAP supplementation. Rumen pH linearly increased with CAP supplementation. The numbers of lymphocytes and eosinophils were linearly increased with CAP supplementation. The use of encapsulated pepper in supplements of crossbred (Holstein x Zebu) bulls managed on D. decumbens pasture up to 450 mg/animal/day improves nutrients digestibility and ruminal fermentation and can positively influence the health status of beef cattle managed under tropical conditions.
Objectives: To evaluate the effect and safety of Cannabidiol (CBD) on behavioral and psychological symptoms in elderly with Vascular dementia (VD).
Methods: Double- blind, randomized, placebo-controlled clinical trial involving elderly patients with VD at the psychogeriatrics and vascular dementia outpatient clinic at Hospital das Clínicas de Ribeirão Preto. The intervention evaluated was the use of CBD 300mg/day compared to placebo. The instruments used are: Neuropsychiatric Inventory, Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression Scale, Side Effects Scale, Mini- Mental State Examination, Brief Cognitive Screening Battery, Katz Index of Independence in Activities of Daily Living, Lawton Instrumental Activities of Daily Living Scale, Informant Questionnaire on Cognitive Decline in the Elderly, Zarit Burden Inventory. The included participants were assessed at the beginning of the study (baseline assessment), in the first, second and fourth weeks after the start of the clinicaltrial.
Results: 30 participants were included. The mixed ANOVA with repeated measures showed that there is an effect of the interaction time and group (F (2.12; 59.43) = 4.02; p < 0.05; ηp2 = 0.13) on the total score of the brief scale psychiatric assessment and neuropsychiatric inventory (F (1.58; 44.31) = 3.61; p =0.05; ηp2 = 0.11). The mixed ANOVA of repeated measures showed no effect of the interaction of time and group for the mini-mental state examination, brief cognitive screening battery. Adverse effects were mild and transient, and similar to the placebo group.
Conclusions: In this study, cannabidiol reduced psychological and behavioral symptoms in patients with vascular dementia. Future studies with larger samples are needed to confirm the findings. (F(1.58;44.31) = 3.61; p =0.05; ηp2 = 0.11). The mixed ANOVA of repeated measures showed no effect of the interaction of time and group for the mini-mental state examination, brief cognitive screening battery. Adverse effects were mild and transient, and similar to the placebo group.
Epilepsy is one of the most common serious brain illness, with symptoms influenced by multiple risk factors and a strong genetic predisposition, rather than having a single expression and cause¹. Neuropsychiatric symptoms in epilepsy can encompass manifestations such as mood alterations, anxiety, sleep disturbances, psychosis, and behavioral disorders. While the motor and sensory manifestations of epileptic seizures are widely recognized, neuropsychiatric symptoms accompanying epilepsy are often underestimated. Therefore, it is essential to understand the most prevalent epidemiological profile of these patients to improve the diagnosis and management of these symptoms.
Objectives
Our goal was to evaluate the neuropsychiatric behavior of epilepsy patients in Brazilian over the past 3 years through hospitalization data in order to outline an epidemiological and behavioral profile.
Methods
A cross-sectional, descriptive, retrospective, and quantitative study was conducted on hospitalizations of individuals simultaneously diagnosed with epilepsy, schizotypal and delusional disorders, and mood disorders in all five regions of Brazil (South, Southeast, Midwest, North, and Northeast) between February 2020 and December 2022. Data from January 2020 were not available. The data used were collected through the Department of Health Informatics of the Brazilian Unified Health System (DATASUS) in the “Hospital Information System of SUS” section, gathering information regarding the nature of care, age range, gender, and ethnicity of the patients.
Results
The analysis covers the years 2020 to 2022, totaling 503,045 hospitalizations. In 2022, the highest number of cases occurred (≈ 37.55%), followed by 2021 (≈ 33.62%) and 2020 (≈ 28.81%). Urgent hospitalizations represented ≈ 90.85% of the total. The most affected age group was 30 to 39 years old (≈ 18.30%). Men were more affected than women (≈ 52.03% and ≈ 47.96%, respectively), and Caucasians accounted for ≈ 36.07% of the hospitalizations. The average length of stay was 19.1 days, and the mortality rate was 1.4%.
Conclusions
Thus, there is a gradual and annual increase in the number of hospitalizations during the observed period. While there is a minimal disparity between the affected genders, it is evident that the profile of male, caucasian, and adult patients is the most prevalent. Moreover, the predominantly urgent nature of hospitalizations points to an alarming scenario regarding this issue. From the analysis of the data obtained in the study, there is a clear need for interventions capable of reducing the prevalence of hospitalizations for neuropsychiatric symptoms in epilepsy patients in Brazil.
Neuropsychiatric disorders are the leading cause of disability worldwide, as seen in cases such as depression, anxiety, bipolar mood disorder and schizophrenia, which can be developed or exacerbated by the use of psychoactive substances. Most mental disorders have an early onset, often leading to early and/or permanent disability, increasing the need and cost of healthcare. Therefore, it is necessary to improve the identification of the epidemiological profile of these cases in the South of Brazil in order to enhance the diagnosis and reduce the costs associated with managing these disorders.
Objectives
The present study aimed to analyze statistical data regarding hospitalizations related to mental disorders caused by the use of psychoactive substances and alcohol in the southern region of Brazil, highlighting the pathological scenario and identifying the most prevalent profiles of these disorders in this region.
Methods
A cross-sectional, descriptive, retrospective, and quantitative study was conducted on hospitalizations of individuals diagnosed with mental and behavioral disorders due to the use of psychoactive substances and alcohol in the states of the Southern region of Brazil (Paraná, Santa Catarina, and Rio Grande do Sul) between February 2020 and December 2022. Data of January 2020 were not available. The data used were collected through the Department of Health Informatics of the Brazilian Unified Health System (DATASUS) in the “Hospital Information System of SUS” section, gathering information regarding the nature of the care, age range, gender, and ethnicity of the patients.
Results
The study covers the years 2020 to 2022, indicating a total of 81,608 hospitalizations, with the year 2022 having the highest number of cases (≈ 37.13%), followed by 2021 (≈ 33.30%) and 2020 (≈ 29.55%). The states with the highest number of hospitalizations were Rio Grande do Sul (≈ 54.90%), Paraná (≈ 29.29%), and Santa Catarina (≈ 15.79%). Urgent hospitalizations accounted for ≈ 87.29% of the total. The most affected age group was 30 to 39 years old (≈ 25.61%). Men were more affected than women (≈ 81.70% and ≈ 18.28%, respectively). Caucasians accounted for ≈ 64.29% of the hospitalizations. The average length of stay was 20.8 days, and the mortality rate was 0.32%.
Conclusions
There is a clear increase in the number of hospitalizations related to mental disorders caused by the use of psychoactive substances in the period from 2020 to 2022 in the southern region of Brazil, with the highest number of cases in the state of Rio Grande do Sul. The most affected population consisted of Caucasian men aged 30 to 39 years old. Furthermore, these results may be related to the increasing trend of psychoactive substance use among the Brazilian population and also the COVID-19 pandemic, which led to a period of underreporting due to social isolation.
Attachment theory, first proposed by John Bowlby and later extended by Mary Ainsworth and others, outlines how experiences of early childhood attachment with caregivers can affect one’s emotional and interpersonal relationships throughout adulthood. Typically, attachment styles are categorised into four main types: secure, anxious-ambivalent, avoidant and disorganised. Conversely, it is recognised that various biological, psychological, relational, social and iatrogenic factors elements can impact an individual’s sexual function.
Objectives
Our aim with this research was to present the most current literature on whether there is a correlation between attachment styles and sexual function.
Methods
We conducted a non-systematic review on the topic using PubMed and PsycInfo.
Results
There is evidence indicating a link between attachment styles and sexual function.
People with secure attachment styles tend to experience more positive and fulfilling sexual relationships. Such individuals typically have a more positive self-image, they feel at ease with emotional intimacy, and are therefore able to openly communicate their needs and desires. They exhibit a healthy balance between seeking closeness and maintaining independence.
Individuals with anxious attachment styles may experience heightened levels of sexual anxiety and insecurity. Concerns regarding rejection or abandonment within sexual relationships may impact their sexual function and satisfaction. These individuals usually have a negative self-image and may be more prone to seek reassurance and validation through sexual activities.
People with avoidant attachment styles may encounter obstacles in developing emotional intimacy and closeness, which can negatively affect their sexual relationships. Such individuals might experience commitment anxiety and prioritise physical aspects of sexual activity over emotional bonding, ultimately decreasing sexual satisfaction for both them and their partners.
Disorganised attachment styles are linked with challenges in regulating their emotions and behaviours in intimate situations, which can have a negative impact on sexual function and satisfaction.
Conclusions
While the literature proposes attachment styles may impact sexual function, it is important to acknowledge other factors that contribute to sexual function. In addition to biological and iatrogenic factors, individual personality, relationship dynamics, past experiences, and cultural influences all have a significant role in shaping one’s sexual behaviour and satisfaction. All of these should be addressed in order to alleviate sexual difficulties.
Moreover, attachment styles may develop and change over time through positive relationships and therapeutic interventions, potentially leading to changes in one’s sexual functioning and relationship dynamics.
In recent years, mental health has gained prominence in public health, prompting thorough investigations into psychiatric condition trends. This study conducts a comprehensive epidemiological analysis of hospitalizations for Schizophrenia, Schizotypal, and Delirium Disorders in Rio Grande do Sul (RS) over the past five years. By revealing these patterns, it enhances our understanding of regional mental health dynamics and offers insights for intervention strategies, resource planning, and improved mental healthcare. The ultimate goal is to advance more effective and accessible mental healthcare in RS and beyond.
Objectives
This study aims to analyze the prevalence and epidemiological profile of hospitalizations due to psychiatric disorders to assist in the diagnosis and outcome of affected patients.
Methods
A cross-sectional, descriptive, retrospective, and quantitative study was conducted regarding hospitalizations for Schizophrenia, Schizotypal Disorders, and Delirium in the state of RS between January 2018 and November 2022. Data were collected from the Department of Informatics of the Brazilian Unified Health System (DATASUS) in the “Hospital Information System of SUS” section, focusing on the nature of care, age group, gender, and ethnicity of the patients. The information was aggregated over the five-year period based on the four mentioned descriptors and subsequently analyzed to establish a profile of hospitalizations during that period.
Results
The analysis spans from 2018 to 2022, encompassing a total of 28,345 hospitalizations. In 2019, there was the highest number of cases (22.21%), followed by 2018 (21.08%). Urgent care admissions constituted 85.34% of the total. The age group most affected was 35 to 39 years (11.8%). Men were more affected than women (60.18%), and the majority of hospitalizations were among the Caucasian ethnicity (75.12%). The average length of stay was 23.7 days, and the mortality rate stood at 0.26%.
Conclusions
The increasing trend in hospitalizations, peaking in 2019, highlights the need for preventive measures. Urgent admissions (85.34%) underscore the demand for accessible mental health resources. Men in the 35 to 39 age group are disproportionately affected, suggesting specific risk factors. The predominance of Caucasian ethnicity emphasizes the need for culturally sensitive care. A longer average length of stay (23.7 days) underscores treatment complexity, while a low mortality rate (0.26%) signals effective medical care. In essence, these findings inform tailored mental health policies to enhance service quality and prioritize patient-centered approaches.
Humanistic studies applied to the health-illness clinic go beyond explaining cause-effect relationships among disease phenomena, treatments, and preventions. Qualitative research aims to understand symbolic relationships built in life experiences among the manifestations and the people. How to act in front of a person whose physical appearance and odour can be unpleasant, such as in the HNC - Head Neck Cancer? Or whose life history may have been marked by deviant behaviours and negligence in self-care?
Objectives
To interpret emotional meanings attributed through open interviews conducted with relatives about the domestic care of patients with HNC under clinical treatment.
Methods
Sample composed of family caregivers of patients with HNC, sent sequentially by colleagues from the clinical service who were informed of the research. The study used the Clinical-Qualitative Method (Turato. Portuguese Psychos. J, 2000 2(1): 93-108). Semi-Directed Interview with Open-ended Questions In-Depth and Field Notes was used for data collection. The employ of the Seven Steps of the Clinical-Qualitative Content Analysis (Faria-Schützer et al. Cien Saude Colet. 2021; 26(1): 265-274) has permitted the understanding of the topics. Sample closed with 12 persons according to the information saturation strategy (Fontanella et al. Cad Saude Publica. 2008; 24(1): 17-27), conducted by the first author, a female psychologist. To interpret the empirical material, we use Medical/Health Psychology, the psychodynamics of relationships of the Balintian framework, disease and illness while modes of un-health, psychic defence mechanisms against anguish. Validation by peers from the Lab of Clinical-Qualitative Research Laboratory, at the State University of Campinas.
Results
For this presentation, we listed three categories from the free-floating re-readings: (1) Certain need to recognize the care provided as a handling strategy with effort, putting in this ‘validation’ their relief regarding natural suffering of the care process; (2) Caregiver’s psychological fantasies of omnipotence in the care process, frequently perceiving the reality a phenomenologically and necessarily distorted by the caregiver. (3) Moments of impotence feeling in front of the finitude reality that it knows will arrive.
Conclusions
The family caregivers can present certain emotional defences, such as subtle magical thinking, in which they distort the reality experienced as a management strategy and validation of their care. They act so to alleviate their psychological and existential suffering. Group meetings with family members to talk openly about the difficulties on the psychological management of patients with HNC, coordinated by a psychotherapist, are effective as a space for creativity in daily management at home and a space for catharsis.
Recent developments in the design of magnetic confinement fusion devices have allowed the construction of exceptionally optimized stellarator configurations. The near-axis expansion in particular has been proven to enable the construction of magnetic configurations with good confinement properties while taking only a fraction of the usual computation time to generate optimized magnetic equilibria. However, not much is known about the overall features of fast-particle orbits computed in such analytical, yet simplified, equilibria when compared with those originating from accurate equilibrium solutions. This work aims to assess and demonstrate the potential of the near-axis expansion to provide accurate information on particle orbits and to compute loss fractions in moderate to high aspect ratios. The configurations used here are all scaled to fusion-relevant parameters and approximate quasi-symmetry to various degrees. This allows us to understand how deviations from quasi-symmetry affect particle orbits and what are their effects on the estimation of the loss fraction. Guiding-centre trajectories of fusion-born alpha particles are traced using gyronimo and SIMPLE codes under the NEAT framework, showing good numerical agreement. Discrepancies between near-axis and magnetohydrodynamic fields have minor effects on passing particles but significant effects on trapped particles, especially in quasi-helically symmetric magnetic fields. Effective expressions were found for estimating orbit widths and passing–trapped separatrix in quasi-symmetric near-axis fields. Loss fractions agree in the prompt losses regime but diverge afterwards.
We identify a set of essential recent advances in climate change research with high policy relevance, across natural and social sciences: (1) looming inevitability and implications of overshooting the 1.5°C warming limit, (2) urgent need for a rapid and managed fossil fuel phase-out, (3) challenges for scaling carbon dioxide removal, (4) uncertainties regarding the future contribution of natural carbon sinks, (5) intertwinedness of the crises of biodiversity loss and climate change, (6) compound events, (7) mountain glacier loss, (8) human immobility in the face of climate risks, (9) adaptation justice, and (10) just transitions in food systems.
Technical summary
The Intergovernmental Panel on Climate Change Assessment Reports provides the scientific foundation for international climate negotiations and constitutes an unmatched resource for researchers. However, the assessment cycles take multiple years. As a contribution to cross- and interdisciplinary understanding of climate change across diverse research communities, we have streamlined an annual process to identify and synthesize significant research advances. We collected input from experts on various fields using an online questionnaire and prioritized a set of 10 key research insights with high policy relevance. This year, we focus on: (1) the looming overshoot of the 1.5°C warming limit, (2) the urgency of fossil fuel phase-out, (3) challenges to scale-up carbon dioxide removal, (4) uncertainties regarding future natural carbon sinks, (5) the need for joint governance of biodiversity loss and climate change, (6) advances in understanding compound events, (7) accelerated mountain glacier loss, (8) human immobility amidst climate risks, (9) adaptation justice, and (10) just transitions in food systems. We present a succinct account of these insights, reflect on their policy implications, and offer an integrated set of policy-relevant messages. This science synthesis and science communication effort is also the basis for a policy report contributing to elevate climate science every year in time for the United Nations Climate Change Conference.
Social media summary
We highlight recent and policy-relevant advances in climate change research – with input from more than 200 experts.
Only two out of three patients diagnosed with First Episode Psychosis (FEP) achieve symptom remission after the administration of two different antipsychotics, illustrating the high prevalence of treatment-resistance in FEP. Of those, 84% are treatment-resistant since illness onset. Response to initial treatment is one of the main long-term illness course predictors. The only medication approved for treatment-resistant psychosis is clozapine and studies have demonstrated its superior antipsychotic effect among this drug class.
Objectives
The aims of this communication are to describe a clinical case of FEP with symptom remission achieved only with clozapine and to review the literature regarding the pattern of clozapine use in FEP, the main difficulties of implementing it and its impact on the prognosis of this patients.
Methods
Relevant data from the patient’s medical record were collected. Pubmed database was searched using the terms “clozapine” and “first episode psychosis”.
Results
A 50 year old woman without previous contact with psychiatric services was taken to the emergency room following behavioural disorganisation and heteroagressive conduct. Poisoning and referential delusions, as well as alienation of personal action and elementary auditory hallucinations were found and the patient was admitted in the psychiatric unit. She began treatment with Aripiprazole without therapeutic benefit and a switch to Paliperidone was made, with the same result. Clozapine was then titrated to a dose of 100mg/day, with resolution of all the positive symptoms mentioned above and she acquired total insight to the disease and need for treatment, being discharged with a diagnosis of schizophrenia. 9 articles, all from 2017 onwards, were collected from the Pubmed database.
Conclusions
There’s reluctance in prescribing clozapine in treatment-resistance FEP. This is evidenced by the mean number of antipsychotic prescribed before clozapine - 2.74 to 4.85 - as well as the delay on its prescription - 294 to 2447 days - and its prescription to only 16% in a cohort of patients with FEP. The main reasons for this hesitation are the serious, albeit rare, side-effects, such as agranulocytosis and myocarditis, as well as the difficulty in implementing it in community services, with mandatory weekly blood tests and very slow titration of the drug and treatment compliance issues, making it a very resource-consuming drug. However, in that same cohort, there was a significant reduction of the number of admissions, re-admissions and duration of hospitalisation, highlighting the need for earlier consideration in treatment-resistant FEP. The identification of treatment-resistance should then be proactive by the mental-health services, ensuring an earlier clozapine initiation with the goal of greatly improving the prognosis of these patients
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.
Objectives
The 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.
Methods
A 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.
Results
Two 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).

Conclusions
We 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.
Suicide is a serious public health problem since it accounts for nearly 900,000 deaths each year worldwide. Globally in 2019, 10.7 persons out of 100,000 died by suicide. Psychiatric disorders are related to an overwhelming proportion of these cases. In the last years, several specific interventions and action plans for suicide prevention have been implemented in a number of European countries.
Objectives
Our aim was to analyze recent epidemiologic trends of suicide mortality rates in Europe.
Methods
Annual national statistics of suicide mortality rates derived from Eurostat public databases from 2011 to 2019 were analyzed for 38 European countries. The suicide mortality rate was estimated per year/100,000 population. Linear regression models were used to study temporal trends of suicidal mortality. Analyses were performed using RStudio.
Results
Available data show a statistically significant reduction in suicide mortality rates from 2011 to 2019 in 15 European countries, and a significant increase for Turkey (ES=0.32, SD=0.06, p=0.037) (Fig 1). The greatest significant decrease was reported in Lithuania (ES=-1.42, SD=0.02, p=0.02), followed by Hungary (ES=-1.13, SD=0.11, p=0.0007), Latvia (ES=-0.76, SD=0.11, p=0.007), and Poland (ES=-0.73, SD=0.10, p=0.001). Italy reported the lowest significant reduction in suicide mortality rates (ES=-0.13, SD=0.018, p=0.003). The remaining 16 countries showed no significant changes in suicide mortality trends.
Image:
Conclusions
In the last years, Europe registered an overall reduction in reported suicide rates. However, more recent data (i.e., suicide rates after COVID-19 pandemic, age and sex-related effect on suicide rates) should be analyzed and used to implement future recommendations. Current and future suicide prevention strategies aim to contribute to a greater reduction of suicide rates in the different European countries.
The term paraphrenia, as classically described by Kraepelin, characterizes a disorder that fits into the complex group of late onset psychoses and resembles schizophrenia, but with better preservation of affect and volition and less deterioration of personality. Over the last few decades, the concept has suffered several setbacks and is not currently recognised by the main manuals of mental disorders. However, there are several authors who argue that the diagnosis of paraphrenia has not lost its usefulness. In 1999, Munro and colleagues proposed a set of criteria to identify this entity and delimit it from the diagnoses of schizophrenia and delusional disorder.
Objectives
Based on a clinical case, we intend to discuss the applicability of the criteria proposed by Munro and the usefulness of the concept of paraphrenia nowadays.
Methods
Case report.
Results
A 71-year-old woman was taken to the emergency department for presenting a first psychotic episode characterized by auditory hallucinations, persecutory delusional ideation and Capgras delirium. The delirium was well structured and very dynamic, interfering in the patient’s social and family spheres. Affects were preserved and adequate and no volitional alterations, thought forms or cognitive deficits were found. Organic pathology was also excluded. Thus, it was possible to make the diagnosis of paraphrenia in light of Munro’s criteria.
Conclusions
The description of this case illustrates the definition and identification of paraphrenia, highlighting the usefulness of the proposed criteria and the importance of giving greater recognition to this entity in order to stimulate future research.
The objective of this study is to provide approaches to determine the mature weight of intact male hair sheep using body composition data. To estimate empty body weight (EBW) at maturity, we used information from eight independent studies comprising a total of 250 intact males in growing and finishing phases. The quantitative data used for each animal were body weight (BW), EBW, water-free EBW protein content, water-free EBW fat content, water-free EBW ash content and EBW water content. The water, protein, fat and ash contents in the EBW and water-free EBW were predicted by non-linear regressions. The best model was chosen considering the achievement of convergence and capacity for biological explanation. The standard deviation of the asymptotic EBW was computed using a simulation method based on a Monte Carlo approach. Among the non-linear evaluations, only the allometric function converged with the parameters within the expected biological limits. To estimate mature EBW, only protein and fat were suitable to predict estimates with the capacity to biological explanation. The water and protein contents in the EBW were closely associated. Animal maturity can be estimated mathematically using body composition. Maturity was reached at an EBW of 47.3 and 57.5 kg when protein and fat were used as a predictor, respectively. We conclude that protein is a good predictor of maturity for intact male hair sheep.
To estimate the cost of metastatic prostate cancer (mPC) treatment using the time-driven activity-based costing (TDABC) method from the perspective of a philanthropic hospital in the Brazilian public health system (PHS) and to identify determinants of costs.
Methods
We used data from patients who received docetaxel chemotherapy in the Brazilian PHS from September 2012 to May 2017. Direct medical costs were estimated with the TDABC microcosting method, taking into account the multiple departments and services the patients interacted with during their oncological treatment.
Results
The median overall survival of the forty-three patient sample was 1.8 years (95% CI 1.45–2.30), and the total cost of the sample was BRL 917.005 (USD 250,878). The median monthly cost per patient was BRL 20.201 (USD 5,526). The end-of-life cost per patient using the TDABC method was BRL 5.151 (USD 1,409). Patients who had received previous treatment at the center registered the lowest cost for hospitalizations and exams, suggesting an opportunity to better manage healthcare resources.
Conclusions
This is the first study on the economic burden of mPC in the Brazilian PHS using the TDABC costing evaluation method. Accurate cost information obtained with the TDABC can be helpful in guiding disease management to guarantee better use of ever-scarcer resources.
The fibrous scaffolds for bone tissue engineering that mimic the extracellular matrix with bioactive and bactericidal properties could provide adequate conditions for regeneration of damaged bone. Electrospun ultrathin fiber covered with nano-hydroxyapatite is a favorable fibrous scaffold design. We developed a fast and reproducible strategy to produce polyvinylidene fluoride (PVDF)/nano-hydroxyapatite (nHAp) nanofibrous scaffolds with bactericidal and bioactive properties. Fibrous PVDF scaffolds were obtained first by the electrospinning method. Then, their surfaces were modified using oxygen plasma treatment followed by electrodeposition of nHAp. This process formed nanofibrous and superhydrophilic PVDF fibers (133.6 nm, fiber average diameter) covered with homogeneous nHAp (202.6 nm, average particle diameter) crystals. Energy-dispersive X-ray spectrometry demonstrated the presence of calcium phosphate, indicating a Ca/P molar ratio of approximately 1.64. X-ray diffraction, Fourier transform infrared spectroscopy, and Raman spectroscopy spectra identified β-phase of nHAp. Thermal analysis indicated a slight reduction in stability after nHAp electrodeposition. Bactericidal assays showed that nHAp exhibited 99.8% efficiency against Pseudomonas aeruginosa bacteria. The PVDF/Plasma and PVDF/nHAp groups had the highest cell viability, total protein, and alkaline phosphatase activity by 7 days after exposure of the scaffolds to MG63 cell culture. Therefore, the developed scaffolds are an exciting alternative for application in bone regeneration.
The production of beef cattle in the Atlantic Forest biome mostly takes place in pastoral production systems. There are millions of hectares covered with pastures in this biome, including degraded pasture (DP), and only small area of the original Atlantic Forest has been preserved in tropics, implying that actions must be taken by the livestock sector to improve sustainability. Intensification makes it possible to produce the same amount, or more beef, in a smaller area; however, the environmental impacts must be assessed. Regarding climate change, the C dynamics is essential to define which beef cattle systems are sustainable. The objectives of this study were to investigate the C balance (t CO2e./ha per year), the intensity of C emission (kg CO2e./kg BW or carcass) and the C footprint (t CO2e./ha per year) of pasture-based beef cattle production systems, inside the farm gate and considering the inputs. The results were used to calculate the number of trees to be planted in beef cattle production systems to mitigate greenhouse gas (GHG) emissions. The GHG emission and C balance, for 2 years, were calculated based on the global warming potential (GWP) of AR4 and GWP of AR5. Forty-eight steers were allotted to four grazing systems: DP, irrigated high stocking rate pasture (IHS), rainfed high stocking rate pasture (RHS) and rainfed medium stocking rate pasture (RMS). The rainfed systems (RHS and RMS) presented the lowest C footprints (−1.22 and 0.45 t CO2e./ha per year, respectively), with C credits to RMS when using the GWP of AR4. The IHS system showed less favorable results for C footprint (−15.71 t CO2e./ha per year), but results were better when emissions were expressed in relation to the annual BW gain (−10.21 kg CO2e./kg BW) because of its higher yield. Although the DP system had an intermediate result for C footprint (−6.23 t CO2e./ha per year), the result was the worst (−30.21 CO2e./kg BW) when the index was expressed in relation to the annual BW gain, because in addition to GHG emissions from the animals in the system there were also losses in the annual rate of C sequestration. Notably, the intensification in pasture management had a land-saving effect (3.63 ha for IHS, 1.90 for RHS and 1.19 for RMS), contributing to the preservation of the tropical forest.
Accurate estimates of methane (CH4) production by cattle in different contexts are essential to developing mitigation strategies in different regions. We aimed to: (i) compile a database of CH4 emissions from Brazilian cattle studies, (ii) evaluate prediction precision and accuracy of extant proposed equations for cattle and (iii) develop specialized equations for predicting CH4 emissions from cattle in tropical conditions. Data of nutrient intake, diet composition and CH4 emissions were compiled from in vivo studies using open-circuit respiratory chambers, SF6 technique or the GreenFeed® system. A final dataset containing intake, diet composition, digestibility and CH4 emissions (677 individual animal observations, 40 treatment means) obtained from 38 studies conducted in Brazil was used. The dataset was divided into three groups: all animals (GEN), lactating dairy cows (LAC) and growing cattle and non-lactating dairy cows (GCNL). A total of 54 prediction equations available in the literature were evaluated. A total of 96 multiple linear models were developed for predicting CH4 production (MJ/day). The predictor variables were DM intake (DMI), gross energy (GE) intake, BW, DMI as proportion of BW, NDF concentration, ether extract (EE) concentration, dietary proportion of concentrate and GE digestibility. Model selection criteria were significance (P < 0.05) and variance inflation factor lower than three for all predictors. Each model performance was evaluated by leave-one-out cross-validation. The Intergovernmental Panel on Climate Change (2006) Tier 2 method performed better for GEN and GCNL than LAC and overpredicted CH4 production for all datasets. Increasing complexity of the newly developed models resulted in greater performance. The GCNL had a greater number of equations with expanded possibilities to correct for diet characteristics such as EE and NDF concentrations and dietary proportion of concentrate. For the LAC dataset, equations based on intake and animal characteristics were developed. The equations developed in the present study can be useful for accurate and precise estimation of CH4 emissions from cattle in tropical conditions. These equations could improve accuracy of greenhouse gas inventories for tropical countries. The results provide a better understanding of the dietary and animal characteristics that influence the production of enteric CH4 in tropical production systems.
The authors intend to characterize the population of foreign patients admitted to Department L of Centro Hospitalar Psiquiátrico de Lisboa, Portuguese biggest Psychiatric hospital, and compare it with published data on the subject.
Methods:
The authors identified all foreigner patients hospitalized in the Inpatient Clinic from 01/01/2010 to 30/06/2011. Clinical information was obtained from the case notes and statistically treated. Relevant literature collected from PubMed was reviewed.
Results:
A great heterogeneity of nationalities was found including 21 countries, the majority of which are a part of CPLP (Community of Portuguese Language Countries). Nearly all of the patients (91%) were in Portugal as immigrants, most being single and unemployed. Housing conditions are unstable. Psychiatric diagnoses show that schizophrenia is the pathology with more expression (27%), followed by major depression (16%) and bipolar disorder (15%). A significant number of patients have disorders due to psychoactive substance use (19%). After discharged from the hospital 77% where referred to outpatient services, but only half of those are still being followed-up.
Discussion:
Social and familial stability is an important factor influencing mental health. Most patients covered by this study experience familiar, professional and housing instability, making them a risk group. Schizophrenia and affective disorders are the most prevalent pathologies, which agrees with the prevailing idea that social distress is a risk factor to them.
Conclusions:
Further studies should be held in order to characterise foreigner populations admitted to psychiatric clinics so that better therapeutic and follow-up measures can be carried out.
