Circadian functioning and quality of life in substance use disorder patients with and without comorbid schizophrenia

Quality of Life Assessment Using the WHOQOL-BREF Survey in Hospitalized Patients with Alcohol Use Disorder from Romania

This cross-sectional analysis aimed to assess the quality of life (QoL) among hospitalized patients with alcohol use disorder (AUD) in Romania, utilizing the WHOQOL survey. Conducted from January to December 2023 in the Psychiatry Clinic of the "Pius Brinzeu" Emergency Clinical Hospital in Timisoara, this study engaged 70 participants, adhering to ethical standards outlined in the Declaration of Helsinki. Employing the WHOQOL-BREF instrument, the research hypothesized that AUD patients would show significantly lower QoL scores across its domains compared to general population norms. The study focused on identifying the QoL domains most impacted by AUD, exploring correlations between QoL scores and AUD background characteristics, and pinpointing intervention areas for patient care improvement. Participants were predominantly males (88.57%) with a middle-aged average of 55.51 years. Educational backgrounds varied, with a notable percentage having attended college (44.29%) or university (17.14%). Regarding marital status, 41.43% were married. Comorbidities were present in 52.86% of the sample, with hypertension being the most common (34.29%). Results showed mean QoL scores in the physical (61.84 ± 16.05), psychological (64.11 ± 17.16), social (60.48 ± 24.85), and environmental (68.44 ± 17.34) domains, revealing a significant diversity in satisfaction levels across these areas. Statistical analyses highlighted marital status as significantly associated with a better QoL in the physical domain, with married, co-habiting, and divorced participants reporting higher scores compared to single ones. In conclusion, while AUD significantly affects the QoL of hospitalized patients in Romania, marital status emerges as a critical factor in mitigating these effects, particularly in the physical domain of QoL. These findings underscore the complexity of AUD's impact on QoL and the importance of considering sociodemographic factors in patient care practices and interventions. The study contributes valuable insights into the nuanced relationship between AUD and QoL, proposing a foundation for enhancing care outcomes for AUD patients in Romania.

Schizophrenia and disruption of circadian rhythms: An overview of genetic, metabolic and clinical signs

A molecular clock in the suprachiasmatic nucleus of the anterior hypothalamus, which is entrained by the dark-light cycle and controls the sleep-wake cycle, regulates circadian rhythms. The risk of developing mental disorders, such as schizophrenia, has long been linked to sleep abnormalities. Additionally, a common aspect of mental disorders is sleep disturbance, which has a direct impact on the intensity of the symptoms and the quality of life of the patient. This relationship can be explained by gene alterations such as CLOCK in schizophrenia which are also important components of the physiological circadian rhythm. The function of dopamine and adenosine in circadian rhythm should also be noted, as these hypotheses are considered to be the most popular theories explaining schizophrenia pathogenesis. Therefore, determining the presence of a causal link between the two can be key to identifying new potential targets in schizophrenia therapy, which can open new avenues for clinical research as well as psychiatric care. We review circadian disruption in schizophrenia at the genetic, metabolic, and clinical levels. We summarize data about clock and clock-controlled genes' alterations, neurotransmitter systems' impairments, and association with chronotype in schizophrenia patients. Our findings demonstrate that in schizophrenia either homeostatic or circadian processes of sleep regulation are disturbed. Also, we found an insufficient number of studies aimed at studying the relationship between known biological phenomena of circadian disorders and clinical signs of schizophrenia.

How sleep quality affects activities of daily living in Parkinson's disease: the mediating role of disease severity and the moderating role of cognition

Objective

The aim of this study was to explore the influential mechanism of the relationship between sleep quality and activities of daily living (ADL) in patients with Parkinson's disease (PD), we hypothesized disease severity as a mediator and assumed the mediating process was regulated by cognition.

Methods

194 individuals with PD (95 women and 99 men) were enrolled in study. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality of PD patients. Patients' ADL, disease severity and cognition were measured by the Unified Parkinson's Disease Rating Scale-II (UPDRSII), Hoehn-Yahr (H-Y) Scale, and Mini-Mental State Examination (MMSE). We investigated the mediating role of disease severity and the moderating effect of cognition on the association between sleep quality and ADL in PD patients.

Results

The score of UPDRSII was positively correlated with the score of PSQI and H-Y stage, while the score of MMSE was negatively correlated with the score of H-Y stage and UPDRSII. Sleep quality predicts disease severity, and disease severity predicts ADL. Disease severity mediated the relationship between sleep quality and ADL, and the mediating effect was 0.179. Cognition alone did not affect ADL, but the interaction between disease severity and cognition was significantly affected ADL, confirming the moderating effect of cognition in PD patients.

Conclusion

Disease severity mediated the association between sleep quality and ADL, good cognition significantly reduced disease severity's mediating influence on the relationship between sleep quality and ADL. Our study indicated a close relationship between ADL and sleep and cognition in PD, and also provided new insights into the overall management of PD and a better quality of life of PD patients.

Design, implementation and preliminary results of a type-2 hybrid cluster-randomized trial of integrating screening and treatment for major depressive disorder into specialty clinics providing opioid agonist therapies in Ukraine

INTRODUCTION

Ukraine has a high prevalence of co-occurring disorders (COD), defined as having both substance use (SUD) and psychiatric disorders. Major depressive disorder (MDD) is the most prevalent psychiatric disorder among people with SUD. People with COD experience poor health outcomes, and international agencies propose integrated COD care. In Ukraine, treatment for SUD is delivered in specialized substance use clinics, without providing any other medical services for comorbidities, including MDD. Here we present the protocol, along the with the preliminary results of the MEDIUM project, including observations over the first 6 months.

METHODS

A cluster-randomized type-2 hybrid trial was conducted to integrate MDD treatment into specialty clinics providing opioid agonist therapies (OAT) in Ukraine. Twelve clinics in four regions underwent randomization to control (N = 1) vs experimental arms (N = 2) in each region. Clinicians at experimental sites received tele-education through modified project ECHO using a facilitated screening, evaluation, and treatment algorithm of depression, with or without financial incentives. Service-, patient- and provider-level data were collected for the analysis every 6 months for 24 months.

PRELIMINARY RESULTS

For service delivery outcomes, 4421 patients enrolled on OAT across all sites were assessed for MDD for screening (76.7%), evaluation with diagnosis (43.5%) and treatment (30.7%) for MDD; 13.8% continued treatment at least for 6 months. For patient-level outcomes, 1345 patients and 54 providers participated in serial surveys every six months.

CONCLUSION

This study will be the first to explore integrated COD care in Ukraine and generate evidence on effective service integration and delivery strategies for people with COD receiving treatment at substance use clinics with broader implications for Eastern Europe and Central Asia region.
