This paper reports an expansion of the English as a second language (L2) component of the Multilingual Eye Movement Corpus (MECO L2), an international database of eye movements during text reading. While the previous Wave 1 of the MECO project (Kuperman et al., 2023) contained English as a L2 reading data from readers with 12 different first language (L1) backgrounds, the newly collected dataset adds eye-tracking data on English text reading from 13 distinct L1 backgrounds (N = 660) as well as participants’ scores on component skills of English proficiency and information about their demographics and language background and use. The paper reports reliability estimates, descriptive statistics, and correlational analyses as means to validate the expansion dataset. Consistent with prior literature and the MECO Wave 1, trends in the MECO Wave 2 data include a weak correlation between reading comprehension and oculomotor measures of reading fluency and a greater L1-L2 contrast in reading fluency than reading comprehension. Jointly with Wave 1, the MECO project includes English reading data from more than 1,200 readers representing a diversity of native writing systems (logographic, abjad, abugida, and alphabetic) and 19 distinct L1 backgrounds. We provide multiple pointers to new venues of how L2 reading researchers can mine this rich publicly available dataset.
This letter presents an improved analytical model for analyzing probe-fed microstrip antennas loaded by metallic vias with lumped terminations. The proposed formulation is based on the resonant cavity model and enables efficient analysis of such perturbed radiators for various types of terminations. The model is validated through the analysis of two antennas: one operating in a TM00 mode and the other with four capacitive terminations to produce circular polarization. Moreover, a reconfigurable RHCP/LHCP antenna based on the patch with capacitive terminations has been manufactured and tested, showing a broadside axial ratio below 0.5 dB at 1.575 GHz.
Haemonchus contortus is one of the most pathogenic gastrointestinal parasites that infect small ruminants. The indiscriminate use of anthelmintics (i.e., benzimidazole class, BZ) to control infections has led to the reduction of drug efficacy in H. contortus populations worldwide. Resistance to BZ is associated with high frequencies of single nucleotide polymorphisms at F200Y, F167Y, and E198A positions of the β-tubulin isotype 1 gene. This study aimed to determine the frequency of single nucleotide polymorphisms associated with BZ resistance in H. contortus from 18 farms (545 sheep and 124 goats) in Paraná, Southern Brazil. Health management practices were identified as risk factors from individual farms. Genomic DNA was extracted from 20,000 larvae/farm and used in quantitative polymerase chain reaction assays for the three mutations. We ran a correlation analysis between flock health and quantitative polymerase chain reaction data. H. contortus was the most prevalent parasite in 67% (12/18) of the farms. Resistant allele frequencies were detected for F200Y (var. 46.4 to 72.0%) and F167Y (var. 15.7 to 23.8%). Only (100.0%) susceptible alleles were detected for the E198A. High treatment frequency (15/18), visual weight estimations for anthelmintic dose (15/18), no integration with other farm practices (14/18), treatment of all animals (14/18), and no quarantine period for newly acquired animals (10/18) were considered the most critical risk factors associated with BZ resistance. This is the first systematic prevalence study linking management practices on smallholder farms and the molecular data of BZ resistance of H. contortus in Southern Brazil.
The challenge of American tegumentary leishmaniasis (ATL) continues in Brazil, presenting a persistent public health issue despite initiatives aimed at public outreach, vector control and health education. To gain a deeper understanding of this disease, a study was conducted in an endemic region located in the northern region of the state of Minas Gerais, Brazil. The study monitored 30 resident patients diagnosed with ATL, using serum samples from 6 healthy individuals as controls. The localized cutaneous form of the disease was found to be predominant, with lesions appearing on various parts of the body and the majority of the affected individuals being male. The study found significantly higher levels of IgG anti-α-Gal antibodies in ATL-infected patients compared to healthy individuals. Treatment of 19 patients with meglumine antimoniate resulted in limited improvement in symptoms for most. Nonetheless, the study found that 12 patients who completed treatment with epithelialization of the lesions showed a significant decrease in IgG anti-α-Gal antibodies, indicating potential applications of this antibody in the diagnosis and monitoring of the disease. The study also identified Leishmania species in 7 analysed patients, revealing 6 cases infected by Leishmania braziliensis and 1 by L. infantum, with a significant difference in the anti-α-Gal responses. The findings of the study emphasize the urgent need for the development of human vaccines and innovative treatment strategies adapted to the diversity of Leishmania species causing cutaneous leishmaniasis and individual patient responses to improve the clinical management of ATL in Brazil and similar endemic regions.
Antipsychotics are the primary class of drugs used to manage schizophrenia. These medications help control and reduce the severity of these symptoms, allowing individuals with schizophrenia to better function. On the other hand, rifampicin, used as treatment for tuberculosis, is a powerful inducer of several drug-metabolizing enzymes which have the potential to decrease the plasma levels of antipsychotics. Therefore, the presence of multiple pharmacokinetic interactions can alter how antipsychotics are metabolized, leading to a notable clinical impact when these medications are administered concurrently.
Objectives
The objective is to share valuable clinical experiences and insights to aid healthcare providers in making informed decisions when faced with the challenge of co-administering antipsychotics with rifampicin, ultimately ensuring the safety and efficacy of treatment for their patients.
Methods
It will be discussed a case of a 41-year-old woman with the diagnosis of schizophrenia under treatment with paliperidone palmitate and clozapine who had a sudden relapse after starting treatment for latent tuberculosis with rifampicin as a framework for a literature review based off Pubmed.
Results
The antituberculosis drug rifampicin induces drug-metabolizing enzymes in the liver, having the greatest effects on the expression of cytochrome P450 (CYP3A4) and therefore can lead to a decrease in the plasma levels of antipsychotic medications that also rely on these pathways for clearance. In this particular case, although specific data on clozapine and paliperidone concentrations were not reported, fluctuations in symptomatology following rifampicin introduction were probably explained by an inducing effect of this drug on their metabolism. So, when initiating rifampicin treatment and when discontinuing it, clinicians should carefully assess the dosages of any concomitant medications that may potentially interact with rifampicin. To ensure effective therapy during rifampicin treatment, it is crucial to monitor both the patient’s clinical response and their blood drug concentrations, making dosage adjustments as necessary.
Conclusions
This case report offers valuable guidance to clinicians on safely and effectively managing drug interactions between antipsychotic medications and rifampicin, ensuring the well-being of their patients during treatment. The co-administration of these medications lacks robust clinical evidence, and notably, there is insufficient data regarding its impact on plasma antipsychotic levels, a crucial factor in determining clinical effectiveness.
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.
Cancer causes an impact in the face of its news, whether due to feelings of anguish, stress and suffering due to the presence of the disease, which can be shared between patients, family members and loved ones. The news regarding the diagnosis generates, in addition to the psychological impact, financial difficulties, as the patient himself can often be responsible for a large part of the family income. Other complications are the difficulties in understanding the disease by the family members and/or the patient, denial of the disease in order to spare the patient from suffering and other loved ones, family conflicts related to the need to adapt to the new routine of daily life that the family should carry out aiming at the well-being of the patient and his treatment.
Objectives
To evaluate the psychological impact and interpersonal relationships in patients with breast cancer treated in the city of Presidente PrudenteSP by a support association.
Methods
This is an observational, quantitative, analytical and cross-sectional study, in which 200 patients with malignant breast cancer will be invited.
Results
The sociodemographic results found were: 62.5% white women, 65.6% aged between 45-65 years, 56.3% married, 46.9% have completed higher education, 56.3% had no family history of cancer, predominance of stages II, III and IV when discovered, 93.5% did not drink, 84.4% did not smoke. On the anxiety scale, 53.1% and 43.8% report getting tired easily and feeling like crying, respectively. On the social adequacy scale, 72.5% continued working only with some limitation during treatment, despite this, 41.4% had minor financial difficulties, 34.5% had difficulties expressing feelings with family members, 40.7% had a relationship well with family members with small arguments and finally 34.8% felt affection for the partner all the time, despite this 36.4% did not have sexual intercourse with them in the last month.
Conclusions
It was concluded, therefore, that when a family member gets sick, they all feel impacted, and each family will deal with the experience in a particular way, therefore, it is worth highlighting the encouragement of family participation in therapy sessions.
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.
Treatment choice when prescribing antidepressants for major depressive disorder (MDD) is often influenced by safety and tolerability profiles. A transient increase in suicidality following antidepressant treatment initiation is a key concern. Although rare, its unpredictability and consequences make them a significant worry. In 2004, the U.S. Food and Drug Administration (FDA) issued a “black-box” warning regarding a potential increase in suicidality in adolescents receiving antidepressant treatment for depression that was later expanded to include both young adults and a broader range of antidepressants.
Objectives
The aim of this study is to evaluate the risk of increased suicidality during the treatment with serotonin and norepinephrine reuptake inhibitors (SNRIs) in young adults with MDD.
Methods
We conducted a non-systematic literature search on PubMed using the combination of MeSH terms ([Serotonin and Noradrenaline Reuptake Inhibitors] OR [Levomilnacipran] OR [Desvenlafaxine Succinate] OR [Venlafaxine Hydrochloride] OR [Duloxetine Hydrochloride]) AND [Suicide] AND [Young Adult], and the keywords [(“Serotonin and Noradrenaline Reuptake Inhibitors” OR “Levomilnacipran” OR “Desvenlafaxine” OR “Venlafaxine” OR “Duloxetine”) AND (“Suicide” OR “treatment-emergent suicidal ideation”) AND (“Young” OR “Youth”)].
Results
A total of 31 manuscripts were retrieved and 6 were selected, 3 original research and 3 non-systematic reviews of randomized clinical trials. Only studies written in English that provided information about suicidality with SNRIs in young adults with MDD.
Globally, studies show that not only antidepressants decrease the risk of suicide attempt in depressed patients, but also there is no evidence of an increased suicidality in young adults treated with SNRIs.
Interestingly, one study showed that increasing suicidality could be related to side effects of the treatment, such as anxiety, agitation and irritability. The authors found that poor antidepressant response and greater severity of depression during follow-up were associated with treatment increasing suicidal ideation, as it was suggested in another study.
Another study reinforced that there may be an emotional component to the activating effects produced by some antidepressants that could explain their controversial association with rare cases of suicidal ideation and behaviour.
Conclusions
In conclusion, growing evidence shows that antidepressants overall decrease the risk of suicide attempt in depressed patients. Therefore, reducing antidepressant use over the FDA concerns about increased suicidal tendencies in young patients may actually increase suicide risks due to inadequate treatment of depression. Additional studies are essential to further confirm the importance of early treatment for depression.
The geochemistry of lake sediments provides valuable information on environmental conditions and geochemical processes in polar regions. To characterize geochemical composition and to analyse weathering and provenance, 26 lakes located in six islands of the South Shetland Islands (SSI) and James Ross Archipelago (JRA) were analysed. Regarding major composition, the studied lake sediments correspond to ferruginous mudstones and to a lesser extent to mudstones. The weathering indices indicate incipient chemical alteration (Chemical Index of Alteration = 52.6; Plagioclase Index of Alteration = 57.6). The La-Th-Sc plot shows different provenance signatures. SSI lake sediments correspond to oceanic island arcs, whereas those of JRA denote a signal of continental arcs with mixed sources. In James Ross Island lake sediments are of continental arcs (inland lakes), oceanic island arcs (coastal lakes) and a middle signature (foreland lakes). Multi-elemental analysis indicates that the sediments are enriched from regional basalts in Ba, Rb, Th, Cs and U (typical of silica-rich rocks) and depleted in Cr and Co due to mafic mineral weathering. The geochemical signals identified by principal component analysis enable us to group the sediments according to the studied islands and their geomorphological characteristics. This study underlines the importance of knowing the geochemical background levels in pristine lake sediments to evaluate potential future anthropogenic effects.
A molecular phylogeographic study of Paragonimus mexicanus collected from Guatemala and Ecuador was performed. Genomic DNA was extracted from individual metacercariae, and two gene regions (partial mitochondrial cytochrome c oxidase subunit 1 (CO1) and the second internal transcribed spacer of the nuclear ribosomal gene repeat (ITS2)) were amplified by the polymerase chain reaction (PCR). Sequences segregated in a phylogenetic tree according to their geographic origins. ITS2 sequences from Ecuador and Guatemala differed at only one site. Pairwise distances among CO1 sequences within a country were always lower than between countries. Nevertheless, genetic distances between countries were less than between geographical forms of P. westermani that have been suggested to be distinct species. This result suggests that populations from Guatemala and Ecuador are genetically differentiated perhaps at the level of subspecies.
The distribution of avian haemosporidians of the genus Leucocytozoon in the Neotropics remains poorly understood. Recent studies confirmed their presence in the region using molecular techniques alone, but evidence for gametocytes and data on putative competent hosts for Leucocytozoon are still lacking outside highland areas. We combined morphological and molecular data to characterize a new Leucocytozoon species infecting a non-migratory red-legged seriema (Cariama cristata), the first report of a competent host for Leucocytozoon in Brazil. Leucocytozoon cariamae n. sp. is distinguished from the Leucocytozoon fringillinarum group by its microgametocytes that are not strongly appressed to the host cell nucleus. The bird studied was coinfected with Haemoproteus pulcher, and we present a Bayesian phylogenetic analysis based on nearly complete mitochondrial genomes of these 2 parasites. Leucocytozoon cariamae n. sp. morphology is consistent with our phylogenetic analysis indicating that it does not share a recent common ancestor with the L. fringillinarum group. Haemoproteus pulcher and Haemoproteus catharti form a monophyletic group with Haemocystidium parasites of Reptilia, supporting the polyphyly of the genus Haemoproteus. We also discussed the hypothesis that H. pulcher and H. catharti may be avian Haemocystidium, highlighting the need to study non-passerine parasites to untangle the systematics of Haemosporida.
Stigma in mental health settings is described as a set of negative and unrealistic beliefs about those with mental illness. Authors suggest that stigma is consistently underdefined and overused, leading to resources toward preventing and managing this problem lacking intention and efficiency. Three interacting levels of stigma are defined: social, structural, and internalized or self-stigma. Internalized stigma refers to how people with mental illness see themselves as mentally unwell and, therefore, of lesser value.
Objectives
We aim to discuss the impact of internalized stigma on psychiatric patients and ways of prevention and stigma resistance.
Methods
We performed a non-systematic literature review from the data base PubMed using the key words “internalized stigma” and “mental illness”.
Results
Internalized stigma is one of the major factors leading to delayed contact with psychiatric care up to two years in outpatients. In psychiatric patients, higher internalized stigma was associated with weakened social support and integration, hopelessness and lower self-esteem and sense of coherence. Low self-esteem is the most significantly associated factor and mediates lower quality of life and higher treatment avoidance. The risk of self-esteem loss seems higher in patients with more insight, especially if they also have a loss of valued social identity. Although some studies suggest higher levels of internalized stigma in female, single and lower educated patients, adjusted statistical analyses do not validate these sociodemographic variations. It is however more prevalent in those with depression and who had been hospitalized because of their mental illness. The impact of internalized stigma is often compared to the levels of the illness burden itself, leading to higher levels of depression and greater psychiatric symptom severity. Additionally, more self-stigma seems to predict suicidal ideation, particularly in young adults.
Conclusions
The internalization of negative stereotypes undermines empowerment and negatively impacts the evolution and recovery of psychiatric patients. There’s strong evidence that general stigma constitutes a risk factor for poor biopsychosocial health outcomes. Programs addressing multiple stigma components seem to be most effective in improving suicide prevention. However, most self-stigma interventions involve groups, which can create barriers for people who are not comfortable disclosing a mental health condition to others. Anti-stigma programs are most effective when they involve people with lived experience of mental health conditions in all aspects of development. Interventions from a younger age should focus on prevention of general stigma by improving understanding of mental illness and reducing self and outwards discrimination. Working on professionals own stigmatizing behaviors is also key to improve the way we communicate and educate populations on how to internally process mental health problems.
Intensive home treatment (IHT) for people experiencing a mental health crisis has been progressively established in many western countries as an alternative to in-ward admission. But is this a real alternative? We previously reported that patients treated in our IHT unit only differ from those voluntarily admitted to hospital in suicidal risk and severe behaviour disorders (not in other factors such as clinical severity) (Martín-Blanco et al., Rev Psiquiatr Salud Ment 2022;15:213-5). Now we are interested in disentangle if those patients who used to require inward management can be successfully treated at home.
Objectives
To describe subsequent treatment trajectories of the first 1000 admissions to our IHT unit and to compare clinical characteristics among the different groups of trajectories.
Methods
Retrospective cohort study. Subsequent treatment trajectories were collected from December 2016 to October 2022 and classified: absence, hospital, IHT, and mixed (hospital and IHT). Statistical significance was tested by means of ANOVA or Kruskal-Wallis test for quantitative variables (corrected for multiple comparisons) and chi-square tests for qualitative variables.
Results
Tables 1 shows the characteristics of the whole sample. Of the 1000 IHT admissions, 12.1% needed subsequent hospital admission(s), 12.7% IHT admission(s), and 9.3% mixed admission(s). There were no differences among these groups in median severity at IHT admission, but there were differences in the number of previous admissions (p=0.0001): the group with no subsequent admissions had less previous admissions than the other groups (pBonf<0.0001), and the group with subsequent IHT admissions had less than the group with mixed admissions (pBonf=0.0123). There were differences between groups regarding distribution of diagnoses (p<0.0001) (Fig. 1). When considering subsequent admissions by diagnosis, there were differences in severity at IHT admission (p=0.0068) and in number of previous hospitalizations (p<0.0001) (Fig. 2).Table 1.

Conclusions
Patients that used to require inward management can now be treated at home when suffering an acute episode. Therefore, IHT has changed treatment trajectories for some patients with psychiatric disorders.
Paraphilias constitute a set of psychiatric conditions that are often chronic and require a combination of treatment approaches, such as pharmacotherapy and psychotherapy. Sexual interest toward prepubescents and pubescents (pedophilia and hebephilia) is frequently identified in criminal settings, within numerous child sexual abuse and child pornography offenses. The high prevalence rates and negative consequences of these acts, causing distress in multiple important areas of health and functioning, reveal the importance of preventing these offenses as a clinical and social matter. Secondary prevention programs, which provide treatment and support for those with paraphilia disorders before sexually abusive behaviors and legal system involvement, show as ethically and socially necessary.
Objectives
We aim to discuss and bring insights into the knowledge on pedophilia and hebephilia treatments and prevention programs, in the fields of psychotherapy as well as pharmacologic strategies.
Methods
We present a non-systematic review of the updated literature on this subject from the data found on the PubMed and PsycInfo databases.
Results
Preliminary results of recent works show that at-risk individuals with paraphilia disorders are often willing to seek treatment without external pressure from the legal system, and report benefits from early treatments. Most studies found that gonadotropin-releasing hormone agonists reduce the risk of child sexual abuse in men with pedophilia. An injectable form has shown to lower this risk 2 weeks after the initial injection, suggesting its use as a rapid-onset treatment option. Cyproterone acetate and medroxyprogesterone acetate are other anti-androgen drugs that inhibit hypersexual behavior, with important side effects to be considered. The combination of androgen deprivation treatment and psychotherapy has a greater effect on preventing fantasies, urges, and behaviours in paraphilic patients. Cognitive-behavioural psychotherapy shows the best results and should soon be initiated in all patients. Biomolecular studies revealed that serotonin and prolactin inhibit sexual arousal, being SSRIs used as first treatment in younger patients, particularly in less severe cases.
Conclusions
Evidence-based treatments from randomized clinical trials for paedophilic and hebephilic disorders are lacking. These current numbers reveal the need for widespread implementation of primary and secondary prevention initiatives, that go beyond the prevention of a repeated offense. There is a need for further research using controlled, randomized trials to examine the effectiveness of sexual offender treatment including psychotherapeutic and pharmacologic interventions. The development of more specific, more effective, and better-tolerated medications for these disorders should be recognized as a program worthy of greater support from government and pharmaceutical industry sources.
Electroconvulsive therapy (ECT) is one of the most controversial treatments in medicine, mainly because of its still unknown mechanism of action and uncertainty about cognitive side effects. ECT is used mainly when antidepressant medications do not result in an adequate response in severe depression, and may also be indicated for other disorders. During the acute phase after electroconvulsive therapy there are better cognitive outcomes with unilateral ECT compared to bilateral ECT.
Objectives
This literature review aims to analyze the validity of electroconvulsive therapy despite the cognitive impairment and effectiveness of electroconvulsive therapy.
Methods
The method used was a literary review based on articles published in Scielo and Pubmed. Eighteen electronic articles in English were used in a 10-year time frame, using the term electroconvulsive therapy as descriptors in the title, as well as cognitive impairment in all fields.
Results
We observed that older individuals benefit the most from ECT, with faster response rates and higher remission rates in rapid responders, on the other hand they have a higher risk of cognitive side effects induced by electroconvulsive therapy. Anterograde and retrograde amnesia usually resolve within months. Recovery from retrograde amnesia may be incomplete, resulting in permanent amnesia for events that occurred close to the time of ECT. Right-sided or bilateral electroconvulsive therapy was more effective in treating depression than left-sided. Patients who used right unilateral electroconvulsive therapy had less impairment of verbal memory and post-ictal recovery and faster reorientation compared to left unilateral and bilateral, whereas left unilateral ECT showed a smaller decline in visual memory and non-verbal tests. Bilateral ECT is more effective and faster acting, but is associated with more cognitive impairments compared to unilateral ECT.
Conclusions
We can conclude that ECT is an effective, safe and tolerable treatment, which results in faster and higher remission rates compared to treatment alone with pharmacotherapy. Cognitive effects are largely transient, usually ending within three months. The decision to use unilateral right, left, or bilateral ECT should be made individually for the patient and should be based on a careful assessment of the relative priorities of efficacy versus minimizing cognitive impairment.
Obsessive‐compulsive disorder (OCD) is a severe condition with a profound impact on the health, social and professional functioning of the patients. More than one third of the patients do not achieve remission of the symptoms after first‐line treatment with cognitive‐behavioral therapy and selective serotonin reuptake inhibitor medication. Neurofeedback is a promising technique that allows the non‐invasive self‐regulation of neural activity associated with symptomatic manifestation. Previous literature reported preliminary evidence of positive effects of functional magnetic resonance imaging (fMRI) neurofeedback on OCD symptoms. However, these studies have small samples and/or were not controlled. Additionally, these studies did not involve treatment‐resistant patients.
Objectives
We aim at developing a fMRI neurofeedback task to treatment-resistant OCD patients and to explore the underlying brain changes.
Methods
We implemented a sham‐controlled double‐blinded fMRI neurofeedback protocol to target hyperactivity in orbitofrontal regions in treatment‐resistant OCD patients with contamination/cleaning symptoms. The protocol had two sessions of neurofeedback (72 min of total training). The patients included were under treatment‐as‐usual.
Results
Our preliminary results with the experimental group (n = 10 patients) demonstrated decreased OCD and stress symptoms three months after the neurofeedback sessions. Moreover, immediately after the neurofeedback sessions, we observed reduced functional connectivity between orbitofrontal and temporoparietal regions, and increased brain activity in dorsolateral prefrontal and premotor areas during symptomatic provocation. The brain functional changes might be associated with a better control over obsessions.
Conclusions
fMRI neurofeedback led to long-term symptomatic reduction in treatment-resistant patients with OCD. Our results need further validation with the sham‐control group but highlight the efficacy of fMRI neurofeedback for refractory OCD and the necessity of prolonged neurofeedback protocols.
Transcranial Magnetic Stimulation (TMS) is a non-invasive neuromodulation tool with a growing body of clinical evidence demonstrating positive outcomes in patients with treatment-resistant depression (TRD) as sole or adjuvant therapy. Theta-burst stimulation (TBS), specifically intermittent TBS (iTBS), uses short intermittent pulse trains to cut each session’s duration to 10% of the original repetitive TMS protocol sessions, making it a more appealing option given that it shows similar efficacy. Nevertheless, the number of sessions required remains the same, with a single protocol lasting around 4 to 6 weeks, or longer. However, a new protocol has very recently been approved by the FDA for application in TRD, called the SAINT (Stanford Intelligent Accelerated Neuromodulation Therapy), which reduces treatment duration to 5 days.
Objectives
To ascertain what evidence supports the SAINT protocol and its efficacy by reviewing available published literature.
Methods
A PubMed database search was performed and the main findings of selected studies were summarized.
Results
Three articles were found, which consisted of clinical trials with small study samples of TRD patients. One study found a 90% remission rate after the aforementioned 5-day treatment regimen, with another reporting a 79% response rate after a double-blinded trial. All studies reported no difference in tolerability compared with regular iTBS protocols.
Conclusions
The SAINT protocol shows promising preliminary results, with efficacy, tolerability and safety of use comparable with that of TMS protocols already in use. The reduction in treatment duration that this intensive option is based on is a significant improvement for applicability in clinical practice, which might increase patient compliance and offer quicker results. Further studies are required to evaluate whether the remission rates are maintained in the long term.
