Expanding the search for emerging mental ill health to safeguard student potential and vocational success in high school: A narrative review

AIM

Young people experiencing mental ill health are more likely than their healthy aged peers to drop out of high school. This can result in social exclusion and vocational derailment. Identifying young people at risk and taking action before an illness is established or school dropout occurs is an important goal. This study aimed to examine evidence for the risk markers and at risk mental states of the clinical staging model (stage 0-1b) and whether these risk states and early symptoms impact school participation and academic attainment.

METHOD

This narrative review assembles research from both the psychiatry and education literature. It examines stage 0 to stage 1b of the clinical staging model and links the risk states and early symptoms to evidence about the academic success of young people in high school.

RESULTS

In accordance with the clinical staging model and evidence from education literature, childhood trauma and parental mental illness can impact school engagement and academic progress. Sleep disturbance can result in academic failure. Undifferentiated depression and anxiety can increase the risk for school dropout. Subthreshold psychosis and hypomanic states are associated with functional impairment and high rates of Not in Employment, Education, or Training (NEET) but are not recognized in the education literature.

CONCLUSION

Risk markers for emerging mental ill health can be identified in education research and demonstrate an impact on a student's success in high school. Clear referral protocols need to be embedded into school life to reduce risk of progression to later stages of illness and support school participation and success.

Sleep disturbance and depression in adolescence: an integrative review of literature

This study investigated the association between sleep disorders and depression in adolescents, PubMed/MedLine, SciELO and Lilacs databases were consulted, with an interval of 7 years (2013-2019), in English, Portuguese and Spanish. An integrative review was carried out where after analyzing the inclusion criteria, 616 articles were selected for reading titles and abstracts and 94 of these were selected for full reading. After the full reading, 15 articles were elected to be part of this review. Results show that both sleep disorders are risk factors for depression, as depression can be a risk factor for sleep disorders. Insomnia was the most frequent sleep disorder in adolescence, besides being considered a public health problem. It is concluded that sleep disorders and depressive symptoms are associated and present with great frequency in the adolescent public.

Changes in Cortisol but Not in Brain-Derived Neurotrophic Factor Modulate the Association Between Sleep Disturbances and Major Depression

Sleep disturbance is a symptom consistently found in major depression and is associated with a longer course of illness, reduced response to treatment, increased risk of relapse and recurrence. Chronic insomnia has been associated with changes in cortisol and serum brain-derived neurotrophic factor (BDNF) levels, which in turn are also changed in major depression. Here, we evaluated the relationship between sleep quality, salivary cortisol awakening response (CAR), and serum BDNF levels in patients with sleep disturbance and treatment-resistant major depression (n = 18), and in a control group of healthy subjects with good (n = 21) and poor (n = 18) sleep quality. We observed that the patients had the lowest CAR and sleep duration of all three groups and a higher latency to sleep than the healthy volunteers with a good sleep profile. Besides, low CAR was correlated with more severe depressive symptoms and worse sleep quality. There was no difference in serum BDNF levels between groups with distinct sleep quality. Taken together, our results showed a relationship between changes in CAR and in sleep quality in patients with treatment-resistant depression, which were correlated with the severity of disease, suggesting that cortisol could be a physiological link between sleep disturbance and major depression.

Sleep pattern and spectral analysis of caregiver-mothers of sons with Duchenne muscular dystrophy, and an examination of differences between carriers and non-carriers

OBJECTIVES

Sleep is essential for physical and mental well-being. However, poor sleep is a common complaint among caregivers. The aim of the present study was to determine sleep patterns of caregiver-mothers (CM group) of sons with Duchenne muscular dystrophy (DMD) and also to examine the differences between non-carriers and carriers of the gene related to DMD within the CM group.

METHODS

Observational case-control study.

PARTICIPANTS

The CM and control (CTRL) groups were matched for age, body mass index and social class. Polysomnography was conducted in a sleep laboratory for one night. The discrete fast Fourier transformation method was used to calculate the electroencephalogram (EEG) power spectrum for the entire night and sleep stages.

RESULTS

The CM group presented higher sleep latency and N3 sleep stage compared with the CTRL. When carrier and non-carrier CM subgroups were analyzed, increased sleep latency and time awake, as well as reduced sleep efficiency and N2, were observed in the carrier group. Regarding respiratory parameters, carriers demonstrated higher hypopnea index values compared with non-carriers. Spectral analysis showed that carriers compared with non-carrier DMD caregiver-mothers presented lower spectral power in fast waves, mainly beta, during REM sleep in some EEG derivations.

CONCLUSIONS

There was an impairment of sleep pattern in the CM group compared with CTRL mothers; this was possibly associated with difficulty in initiating sleep. Being a DMD gene carrying caregiver further compromised some aspects of sleep microstructure during REM sleep. The data demonstrated the importance of sleep evaluation in caregiver-mothers, and the relationship between sleep and being a carrier of the gene associated with DMD, which was demonstrated as possibly impacting sleep quality.

Subjective sleep quality and sleep duration of patients in a psychiatric hospital

Sleep complaints and sleep disturbances are highly prevalent in patients with psychiatric disorders. During hospitalization the patients’ condition may be even worse but little is known about the subjective sleep quality in psychiatric hospitals. Thus, we have investigated subjective sleep quality and mean sleep duration in patients with different psychiatric disorders at the end of hospitalization. For a period of one year, inpatients of a psychiatric hospital with diagnosis of substance use disorder (SUD), schizophrenia (SCZ), or anxiety/depressive disorders (AND) were routinely asked to fill in an easily comprehensible sleep quality questionnaire at the end of their hospitalization. Age, gender, subjective sleep quality, and sleep duration were analyzed; sleep duration was classified according to age-specific recommendations. Data of n=309 patients (age 52.1±17.9y, 56.1% women) were analyzed (n=63 SUD, n=50 SCZ, n=196 AND). Mean sleep duration was 7.0±2.0 h; 20.7% of patients had sleep durations below and 4.5% above age-specific recommendations. Non-restorative sleep during hospitalization was reported “almost always” in 38.2% (n=118), and “occasionally” in 30.1% (n=93). Subjective sleep quality was significantly associated with sleep duration (r_s=−0.31, P<0.0005), but not with age, gender or diagnostic subgroup. The study showed that a great proportion of patients reported poor subjective sleep quality during hospitalization, regardless of age, gender and psychiatric diagnosis. As sleep quality was significantly associated with short sleep duration, a first step could be to take care to achieve recommended age-specific sleep durations in psychiatric hospitals.

Associação da depressão com as características sociodemográficas, qualidade do sono e hábitos de vida em idosos do Nordeste brasileiro: estudo seccional de base populacional

Introdução: Os transtornos depressivos podem ser definidos como episódios de humor deprimido ou perda de interesse e prazer por quase todas as atividades. A depressão é considerada o principal transtorno mental em idosos, podendo relacionar-se com a qualidade do sono e hábitos de vida, além de ser influenciada por questões sociodemográficas.Objetivo: Verificar a prevalência de depressão em idosos no interior do Nordeste brasileiro e qual a sua relação com o perfil sociodemográfico, qualidade do sono e hábitos de vida. Método:Delineou-se um estudo epidemiológico do tipo transversal, tendo como base a população idosa da zona urbana de Campina Grande-PB. Foi investigada a presença de depressão como variável dependente, assim como aspectos sociodemográfios, qualidade do sono e hábitos de vida como variáveis independentes. Foram obtidas estimativas de prevalência das variáveis e medidas de associação por meio de regressão de Poisson. Adotou-se um nível de significância de 5% para as estimativas.Resultados: Participaram do estudo 168 idosos com idade média de 72,3 (±7,8) anos, sendo em sua maioria mulheres, 122 (72,6%). O quadro depressivo foi identificado em 72 idosos (42,9%). As idosas estavam duas vezes mais associadas ao quadro depressivo (RP=2,26) que os homens. A qualidade subjetiva do sono muito bom (RP=0,34), o médio/alto risco de distúrbio do sono (RP=4,08), tomar medicações para dormir uma ou duas vezes na semana (RP=5,21) e três vezes ou mais (RP=8,69), disfunção diurna uma ou duas vezes por semana (RP=14,40) e três vezes ou mais (RP=27,00) e má qualidade do sono no índice de Pittsburgh apresentaram associação com a depressão na análise bivariada, mas sem relação após ajustamento multivariávelConclusion:A prevalência de depressão mostrou-se elevada na população estudada, sendo claramente mais frequente nas idosas. Por outro lado, não foi possível detectar associação da depressão com os hábitos de vida e a qualidade do sono.

Associação de sintomas depressivos e ansiosos com gravidade da migrânea

Objetivo O objetivo do presente estudo foi avaliar a associação do sono, depressão e ansiedade em pacientes com migrânea. Métodos Cinquenta pacientes do sexo feminino, provenientes de um centro terciário de tratamento de cefaleias, com o diagnóstico de migrânea segundo os critérios da International Headache Society, foram incluídas neste estudo. As pacientes foram avaliadas com os seguintes instrumentos: Migraine Disability Assessment test (MIDAS), Headache Impact Test (HIT), Hospital Anxiety (HADS-A) and Depression Scale (HAD-D), Índice de Qualidade do Sono de Pittsburgh (IQSP) e Escala de Sonolência de Epworth (ESE). Resultados As pacientes apresentaram alta prevalência de sintomas de ansiedade (60%) e de depressão (42%), má qualidade do sono (80%) e sonolência diurna (36%). Foi demonstrada correlação positiva entre a gravidade dos sintomas de ansiedade e HIT (p = 0,018; ρ = 0,334), ESE (p = 0,002; ρ = 0,426) e IQSP (p = 0,002; ρ = 0,426). Correlação positiva também foi demonstrada entre a gravidade dos sintomas depressivos e HIT (p < 0,001; ρ = 0,532), ESE (p = 0,035; ρ = 0,299) e IQSP (p = 0,016, ρ = 0,34). Não houve associação entre a qualidade do sono, a sonolência diurna e a gravidade da migrânea. A pontuação na HAD-D foi o principal preditor de impacto grave da migrânea. Conclusão Apesar da alta frequência de distúrbios do sono, o principal fator relacionado ao impacto da migrânea foi a gravidade dos sintomas depressivos.

Ocorrência de sintomas depressivos em médicos que trabalham no programa de saúde da família

Objetivo Avaliar a ocorrência de depressão entre os médicos que trabalham nas Unidades de Saúde da Família (USF) em Aracaju. Métodos Em uma amostra de 83 médicos, foram utilizados o Inventário de Depressão de Beck (IDB) para rastreamento dos sintomas depressivos e um questionário elaborado pelos pesquisadores para coletar informações sociodemográficas. Foram realizadas estatística descritiva e análise por meio do qui-quadrado e regressão logística. Resultados A prevalência de sintomas depressivos na amostra foi de 27,7% (IC 95% 19,3-37,3). Observou-se que as variáveis que tiveram associação com o aparecimento dos sintomas (p < 0,05) foram: problemas de relacionamento, grau de satisfação com o trabalho e o número de consultas em relação à hora de trabalho. Após ajuste de regressão logística múltipla, foi observado que os médicos que tinham problemas de relacionamento e os insatisfeitos com o trabalho apresentaram, respectivamente, 5,63 e 4,59 vezes mais sintomas depressivos quando comparados àqueles que não possuíam esses sintomas Conclusões . A prevalência de sintomas depressivos em médicos que trabalham nas USF de Aracaju é alta e provavelmente está associada ao trabalho e a problemas de relacionamento.

Do sleep abnormalities and misaligned sleep/circadian rhythm patterns represent early clinical characteristics for developing psychosis in high risk populations?

Sleep architecture changes, such as slow-wave sleep (SWS) percentage variations and reductions in latency and density of rapid eye movement (REM), are found in most patients with schizophrenia and are considered to be an important part of the pathophysiology of the disorder. In addition to these sleep parameters changes, disruptions in sleep homeostasis and the sleep/circadian rhythm also occur in these patients. Sleep/circadian rhythm abnormalities negatively affect neocortical plasticity and cognition and often precede the diagnosis of the illness. Thus, it has been suggested that the sleep/circadian rhythm might be involved in the pathophysiology of psychosis. Recent advances in the identification of individuals at a high risk for developing schizophrenia allow us to investigate several neurobiological processes involved in the development of psychosis. In this article, we review the current evidence of the effects of sleep parameter abnormalities, disruptions in sleep homeostasis and misalignments of sleep circadian rhythm on the early stages of schizophrenia. In addition, we discuss the preliminary evidence of sleep and circadian rhythm abnormalities during the prodromal stages of psychosis and propose that these abnormalities can be explored as potential predictors, as an adjunct to clinical diagnosis, of developing a psychotic disorder in at risk populations.

Significant sleep disturbances in euthymic bipolar patients

OBJECTIVE

A growing amount of data suggests that sleep dysfunction is frequently observed in bipolar disorder (BD) patients even when they do not fulfill the criteria for major mood episodes. Thus, we performed a case-control study assessing sleep status in a group of euthymic BD patients and a group of health controls.

METHODS

A total of 209 subjects (104 health controls and 105 BD patients) were enrolled in the study. The Pittsburgh Sleep Quality Index (PSQI) was used for sleep assessment. Inclusion criteria for the BD group were a diagnosis of BD, following DSM-IV-TR criteria, according to the MINI-plus structured clinical interview. Euthymia was established as a score lower than 7 both in the Hamilton Depression Rating Scale (HDRS) and in the Young Mania Rating Scale (YMRS). Health controls were also interviewed using the MINI-plus and included in this study if they were free of any current or past DSM-IV-TR axis I psychiatric disorder as well the actual use of psychopharmacological medications.

RESULTS

While 21.2 % of the control group displayed poor sleep quality according to the global PSQI-BR score, 82.9 % of the euthymic BD patients had poor sleep quality (p=0.000). PSQI sleep duration subcomponent showed comparable results in the two groups (p=0.535), even though BD patients had significant disruptions in sleep latency (p=0.000) and sleep efficiency (p=0.000) subcomponents.

CONCLUSION

We were able to show that BD patients, even in euthymic phase, exhibit a significantly worse sleep quality as compared with health controls as assessed by PSQI total score and five of its seven subcomponents.

O metifenidato no Brasil: uma década de publicações

O metilfenidato é um estimulante comercializado desde os anos 50 na Suíça, na Alemanha e nos EUA. Mas foi somente a partir de sua associação com o Transtorno do Déficit de Atenção e Hiperatividade (TDAH) que suas vendas alavancaram, tornando-se o estimulante mais consumido no mundo. Este artigo tem por objetivo apresentar os resultados de uma análise das publicações brasileiras sobre os usos do metilfenidato no Brasil, ao longo da última década. Com isto, visa compreender como as informações são apresentadas ou omitidas nos diferentes espaços de divulgação impressa. Para tal análise, foram pesquisadas publicações científicas, nos principais periódicos de psiquiatria brasileiros, e reportagens de jornais e revistas nacionais destinados ao público em geral. A pesquisa inclui as publicações do período de 1998 a 2008. Destaca-se como ponto relevante da análise a importante participação dos laboratórios no financiamento dos grupos e pesquisas sobre TDAH. Os achados indicam que a combinação do uso do medicamento com psicoterapias, a dependência do medicamento e a ideia de que existe excesso de prescrição no Brasil são temas controversos nas publicações analisadas.

PSYCHE: personalised monitoring systems for care in mental health

One of the areas of great demand for the need of continuous monitoring, patient participation and medical prediction is that of mood disorders, more specifically bipolar disorders. Due to the unpredictable and episodic nature of bipolar disorder, it is necessary to take the traditional standard procedures of mood assessment through the administration of rating scales and questionnaires and integrate this with tangible data found in emerging research on central and peripheral changes in brain function that may be associated to the clinical status and response to treatment throughout the course of bipolar disorder. This paper presents PSYCHE system, a personal, cost-effective, multi-parametric monitoring system based on textile platforms and portable sensing devices for the long term and short term acquisition of data from selected class of patients affected by mood disorders. The acquired data will be processed and analyzed in the established platform that takes into account the Electronic Health Records (EHR) of the patient, a personalized data referee system, as well as medical analysis in order to verify the diagnosis and help in prognosis of the illness. Constant feedback and monitoring will be used to manage the illness, to give patients support, to facilitate interaction between patient and physician as well as to alert professionals in case of patients relapse and depressive or manic episodes income, as the ultimate goal is to identify signal trends indicating detection and prediction of critical events.

Tratamento não farmacológico para a insônia crônica

O objetivo deste artigo é descrever, resumidamente, quais são as terapias não farmacológicas e também a atualização do uso destas para o tratamento da insônia crônica. Além da insônia ser o mais prevalente distúrbio do sono, ela está diretamente associada aos transtornos psiquiátricos. Embora o tratamento farmacológico seja o mais comumente utilizado, as terapias não farmacológicas vêm sendo amplamente estudadas, em particular as relacionadas às mudanças de comportamento. Entre estas estão a cognitiva; a higiene do sono; a do controle de estímulos; a de restrição do sono; a do relaxamento muscular; a da intenção paradoxal e, mais recentemente, a prática regular de exercícios físicos. Inicialmente, o principal objetivo dos estudos realizados com as intervenções comportamentais foi o de melhorar a qualidade do sono dos pacientes. No entanto, alguns estudos recentes têm sido desenvolvidos com o objetivo de avaliar o efeito de tais terapias auxiliando à redução da dose e da freqüência de uso de medicamentos utilizados, bem como à melhora da qualidade de vida dos pacientes. Como a insônia é um problema crônico, os tratamentos de longo prazo têm sido alvos de estudos e de uso comum entre os clínicos.

Comparative analysis of multiple sleep latency tests (MSLT) parameters and occurrence of dreaming in patients with daytime sleepiness of narcoleptic and non-narcoleptic origin

OBJECTIVE

To compare MSLT parameters in two groups of patients with daytime sleepiness, correlated to the occurrence and onset of dreams.

METHOD

Patients were submitted to the MSLT between January/1999 and June/2002. Sleep onset latency, REM sleep latency and total sleep time were determined. The occurrence of dreams was inquired following each MSLT series. Patients were classified as narcoleptic (N) or non-narcoleptic (NN).

RESULTS

Thirty patients were studied, 12 were classified as narcoleptics (N group; 40%), while the remaining 18 as non-narcoleptic (NN group; 60%). Thirty MSLT were performed, resulting in 146 series. Sleep was detected in 126 series (86%) and dreams in 56 series (44.44%). Mean sleep time in the N group was 16.0+/-6.3 min, while 10.5+/-7.5 min in the NN group (p<0.0001). Mean sleep latency was 2.0+/-2.2 min and 7.2+/-6.0 min in the N and NN group, respectively (p<0.001). Mean REM sleep latency in the N group was 3.2+/-3.1min and 6.9+/-3.7 min in the NN group (p=0.021). Dreams occurred in 56.9% of the N group series and 28.4% in that of the NN group (p=0.0009). Dream frequency was detected in 29.8% and 75% of the NREM series of the N and NN groups, respectively (p=0.0001).

CONCLUSION

Patients from the N group, compared to the NN group, slept longer and earlier, demonstrated a shorter REM sleep onset and greater dream frequency. NN patients had a greater dream frequency in NREM series. Thus, the occurrence of dreams during NREM in the MSLT may contribute to differentially diagnose narcolepsy and daytime sleepiness.

Excessive daytime sleepiness in patients with depressive disorder

OBJECTIVE: To evaluate excessive daytime sleepiness in patients with depressive disorder and to examine its association with the severity of depression and suicidal ideation. METHOD: Seventy patients were interviewed and assessed by the Epworth Sleepiness Scale (ESS), the Beck Depression Inventory (BDI) and the Beck Scale for Suicidal Ideation (SSI). Descriptive analysis, Pearson correlations and Student's t-test were used for data analyses. RESULTS: Most of the patients (57.1%) obtained high scores on the ESS. Correlation was positive and strongly significant between ESS scores and BDI scores, as well as between ESS scores and SSI scores. Patients with high ESS scores obtained higher mean BDI and SSI scores in comparison to patients with lower ESS scores. Significant differences (p < 0.05) were encountered when the patients with higher (>10) and lower (< 10) ESS scores were compared in terms of total ESS, BDI and SSI scores. CONCLUSIONS: Excessive daytime sleepiness was frequent among patients and significantly associated with higher levels of depression and particularly with suicidal ideation. Thus, a careful investigation of daytime sleepiness in depressed patients is required during clinical evaluation.
