The dual burden of tuberculosis (TB) and diabetes mellitus (DM) presents a growing challenge for health systems in low- and middle-income countries (LMICs), including Pakistan. Despite global and national policies advocating for integrated care, evidence on health facility readiness to operationalize integration remains scarce. This study assessed the readiness of TB basic management units (BMUs) to deliver integrated TB-DM care and explored implementation barriers using the Consolidated Framework for Implementation Research (CFIR).
Methods:
We conducted an explanatory sequential mixed-methods study from September 2024 to February 2025 across 13 TB BMUs in five districts of Pakistan. Quantitative readiness data were collected using a structured tool adapted from the WHO Service Availability and Readiness Assessment (SARA), generating a composite score across four domains. Subsequently, qualitative data were gathered through multi-stakeholder focus group discussions with healthcare providers, facility managers, patients, caregivers, and policymakers. Reflexive thematic analysis was conducted and mapped to CFIR Inner Setting constructs to contextualize quantitative findings.
Results:
Only one facility demonstrated high readiness, while 12 showed low readiness. Facilities lacked routine comorbidity screening, trained staff, diagnostic capacity, and essential medicines. Key barriers included inadequate infrastructure, workforce shortages, fragmented information systems, and low prioritisation of integrated care. Financial constraints and limited coordination further hindered implementation.
Conclusion:
This study highlights critically low readiness among TB facilities in different districts of Pakistan to deliver integrated TB-DM care, reflecting systemic weaknesses across core domains. Strengthening systems, building capacity, and improving integration strategies are essential to bridge gaps between policy and practice.
Dual disorder, comprising of substance use and mental health disorders, requires a comprehensive treatment approach. The most effective is integrated dual disorder treatment, which involves addressing both conditions concurrently by the same specialists and in the same setting. This study examines characteristics of integrated dual disorder care offered by treatment services across European countries.
Methods:
In 2022, representatives of 14 integrated care for dual disorder providers in 10 European countries were asked to respond to a survey about their treatment process, outcomes, barriers and facilitators when implementing dual disorder treatment in respective countries. Thematic qualitative analysis was used to explore closed- and open-ended responses, focusing on commonalities and differences between surveyed services.
Results:
Integrated care services varied in treatment settings and structure, but all offered comprehensive support for dual disorder. Among 14 services, half addressed tobacco addiction or provided suicide prevention, three treated cannabis use, and none accepted patients in opioid agonist therapy. Few services reported evaluating treatment outcomes in standardised way. Services supported patients with social security, employment, housing and education, but also noted difficulties in coordinating post-treatment care due to divergent views on dual disorder among specialists from different services.
Conclusions:
Integrated care services provide comprehensive and tailored support for people with dual disorder but remain distinct within the healthcare options available to this patient group across Europe. Existing and future integrated care services would benefit from addressing tobacco and cannabis use, measuring treatment outcomes and improving continuity of care.
Antipsychotics used to treat severe mental illness (SMI) markedly raise the risk of metabolic syndrome. Early weight gain predicts worse outcomes, making timely intervention vital, particularly within the first 6 months, when the most weight loss is achievable. This meta-analysis evaluated non-pharmacological weight/body mass index (BMI) management interventions during the first 6 months of their use in people receiving antipsychotics for SMI, to identify effective components with the aim of preventing long-term metabolic complications. Systematic searches of five databases (to October 2024) yielded 1483 studies; 8 (643 participants) met inclusion criteria. Interventions included exercise, nutrition, education, monitoring and psychological input, delivered individually or in groups.
Results
Meta-analysis showed significant weight (−1.93 kg) and BMI (−1.12 kg/m2) reductions. Group-based, multi-component programmes with psychological input were most effective.
Clinical implications
Group-based, multi-component interventions that include a psychological element produced the greatest reductions in weight and BMI. Future research should focus on refining and embedding psychologically informed, multi-component group programmes into routine psychiatric care to optimise long-term physical health outcomes.
People with severe mental illness (SMI) die 10–20 years earlier than the general population, largely due to non-communicable diseases (NCDs) such as hypertension and diabetes and risk factors such as hypercholesterolaemia. This cross-sectional study gathered data from people with SMI from three national mental health institutions in South Asia. Data was collected based on the WHO Stepwise approach to NCD risk factor surveillance and the prevalence of screening, diagnosis and treatment for diabetes, hypertension, and hypercholesterolaemia was assessed. Logistic regression models assessed the associations of sociodemographic characteristics with NCD screening. Three thousand nine hundred and eighty nine participants were recruited. Screening prevalence varied by country and disease, with hypertension being the most commonly screened NCD (Bangladesh = 52.5% [50.0–55.1], India = 43.1% [40.3–45.9], Pakistan = 60.9% [58.2–63.5]), and cholesterol was the least common (Bangladesh = 4.1% [3.2–5.2], India = 14.8% [12.9–17.0], Pakistan = 9.6% [8.1–11.3]). Characteristics such as BMI, age and education level were positively associated with screening, and females were more likely to be screened than males. There are low levels of screening for NCDs among individuals with SMI accessing tertiary institutions in South Asia, with significant sociodemographic disparities. Standardised screening protocols tailored to South Asian populations could mitigate the increased risk of NCDs in this population.
A clinic to assess and treat mental health (MH) within a community substance use disorder (SUD) service has been implemented with the aim to facilitate engagement, progress, and completion of substance use treatment.
Methods:
This study was completed to assess the effectiveness of such an integrated service. The records of individuals seen within the clinic during 2022 and 2023 were assessed for the reason for referral, diagnosis, and treatment offered, and outcome of MH and SUD.
Results:
A total of 118 individuals were assessed. The majority (58%) were referred due to a lack of progress in treatment. The most frequent MH diagnosis was bipolar disorder (57%), followed by smaller numbers of diagnoses of psychosis, PTSD, anxiety and depression. Seventy-four (63%) individuals improved in MH, and eighty (68%) in SUD.
Conclusions:
Despite the limitations due to the naturalistic methodology, this early work suggests that an integrated type of provision of MH treatment within a SUD service might have a beneficial complementary role within the existed parallel treatment model implemented in England.
Known influences on tic severity include medical, biological and contextual factors.
Aims
We aimed to further understanding of contextual factors by exploring if tic severity is influenced by calendar month.
Method
This study used data from the Calgary Child Tic Registry. Children are extensively clinically phenotyped at their first visit and followed prospectively until adulthood. We evaluated the mean Yale Global Tic Severity Scale-Revised (YGTSS-R) total tic severity score based on the calendar month. Multivariable linear regression models were fit to assess the individual months adjusted for age, gender, comorbidity and tic treatment variables.
Results
The study included 370 participants, with 549 assessments of tic severity performed. In the univariable analysis based on calendar month, August had the lowest tic severity, with a mean YGTSS-R total tic severity score of 15.68 (95% CI 13.41–17.95). This was significantly lower than the month with the highest tic severity, February, with a mean score of 20.41 (95% CI 18.19–22.63). In multivariable models adjusted for age, gender, comorbidity and treatment for tics, the omnibus test for whether month contributes to a better fit were not significant (YGTSS-R total tic score P-value: 0.495). The only significant predictors of increased tic severity were treatment for tics (P < 0.0001), diagnosis of depression (P = 0.003) and diagnosis of obsessive–compulsive disorder (P = 0.02).
Conclusions
While our univariate analysis of tic severity by calendar month supported significantly lower tic severity in August compared with February, this association was no longer statistically significant when controlling for other variables known to impact tic severity.
In 2018, the UK government commissioned National Health Service Talking Therapies (NHS TT) services to provide integrated mental and physical health care for individuals with a long-term condition (LTC) and coexisting depression and/or anxiety. Nevertheless, evidence on the effectiveness of NHS TT in physical LTCs remains inconsistent.
Aims
This review aims to evaluate the impact of NHS TT on mental health outcomes among adults with physical LTCs.
Method
We conducted a systematic review and meta-analysis of quantitative studies published between 2008 and 2024. We used several databases for the search, including Embase, MEDLINE, Cochrane Library, NHS Evidence, PsycINFO, Bielefeld Academic Search Engine and ProQuest. We combined terms related to NHS TT, LTCs and mental health outcomes to identify eligible studies. The Population, Intervention, Comparison, Outcomes and Study framework guided the development of the inclusion criteria. We employed the random-effects model for meta-analysis and assessed heterogeneity bias using the I2 statistic, and the Newcastle–Ottawa scale to evaluate the overall quality of the evidence.
Results
Twenty-four studies met the inclusion criteria. The meta-analysis revealed a significant pre–post NHS TT intervention effect on reliable improvement (odds ratio 0.77, 95% CI: 0.60–0.98) and reliable recovery (odds ratio 0.80, CI: 0.68–0.95). There were no significant differences in NHS TT accessibility (e.g. treatment engagement) between participants with and without LTCs (odds ratio 0.97, 95% CI: 0.82–1.14). However, heterogeneity between the studies was high (>90%).
Conclusions
The observed evidence provides reassurance for individuals with LTCs engaging with treatment; however, the association with post-treatment distress is still of concern. Furthermore, extensive and rigorous research is needed to strengthen and guide service development for individuals with LTCs, thereby improving effectiveness.
Bipolar disorder and attention-deficit/hyperactivity disorder (ADHD) share overlapping clinical symptoms and cognitive deficits. Up to 20% of individuals with bipolar disorder also meet the criteria for ADHD (bipolar disorder + ADHD), a subgroup that may experience greater cognitive and functional impairments than those with bipolar disorder or ADHD alone.
Aims
To (a) characterise cognitive profiles in bipolar disorder, ADHD and bipolar disorder + ADHD compared with healthy controls; (b) examine associations between cognitive and occupational functioning; and (c) investigate associations between cognitive function and polygenic scores (PGS) for bipolar disorder, ADHD and educational attainment.
Method
In this observational study, 477 euthymic individuals with bipolar disorder (including 78 with bipolar disorder + ADHD), 59 adult individuals with ADHD and 171 healthy controls completed standardised neuropsychological testing. Full-scale IQ and final school grades indexed current and premorbid cognitive ability, respectively. Occupational functioning was evaluated both cross-sectionally and through 5 years of registry-based follow-up. PGS were available for 295 bipolar disorder and 132 healthy control participants.
Results
All patient groups performed significantly below healthy controls across most cognitive domains. Bipolar disorder + ADHD exhibited poorer working memory than bipolar disorder (d = −0.35, 95% CI [−0.66, −0.03]). Occupational function was lowest in bipolar disorder + ADHD (versus bipolar disorder, d = −0.44, 95% CI [−0.69, −0.19]). In bipolar disorder, poorer executive function (standardised regression coefficient (standβ) = 0.20, 95% CI [0.09, 0.31]) and older age predicted reduced occupational outcomes. PGS for educational attainment was associated positively with cognition in both bipolar disorder (working memory: standβ = 0.19, 95% CI [0.08, 0.30]) and healthy controls (executive function: standβ = 0.20, 95% CI [0.09, 0.32]), while PGS for bipolar disorder or ADHD were not significantly associated with cognitive performance.
Conclusions
Individuals with bipolar disorder + ADHD showed disproportionate working memory and functional impairment compared with bipolar disorder or ADHD alone. Executive function is a key predictor of occupational outcomes in bipolar disorder and is partly shaped by genetic propensity for educational attainment. These findings highlight the importance of considering ADHD comorbidity and cognitive profiles when evaluating functional prognosis and tailoring interventions.
Continuous traumatic stress (CTS) exposure describes extended and ongoing collective trauma exposure that is associated with potential future danger and threat to the community. CTS has generated debate in the context of current definitions of trauma and posttraumatic stress disorder (PTSD) in the DSM-5. Prevalence data on posttraumatic stress symptoms (PTSS) and PTSD in adolescents aged 10 to 24 years following CTS exposure in Sub-Saharan Africa are lacking. This systematic review and meta-analysis sought to address this gap. We also synthesized evidence on other trauma-related mental disorders and moderators such as mean age, sex, country income, education level, PTSS/PTSD assessment tool, and recruitment method. A systematic literature search covering four databases yielded 460 papers that were screened for eligibility, with 10 studies included. Data were extracted and coded, and a meta-analysis of the pooled prevalence of clinically significant PTSS/PTSD was conducted. Results indicated a pooled prevalence of PTSS/PTSD of 32.0% (95% CI: 20.7% to 46.0%). Country income (World Bank category) and type of assessment (clinician-administered vs. self-report) significantly moderated the prevalence of PTSS/PTSD. Further research is needed to not only measure CTS as an exposure but also as a response separate from PTSS/PTSD among adolescents in Sub-Saharan Africa. Additionally, research is needed to determine the validity, reliability, and cultural relevance of CTS response measures. Such studies will help in better understanding the psychosocial impact of CTS exposure on adolescents and inform the development of future interventions. Detailed data on the prevalence of PTSS/PTSD and moderators thereof following CTS exposure in Sub-Saharan Africa are sparse. Further studies are needed to characterize CTS-related comorbidities and related phenomena in adolescents living under conditions of CTS exposure and to optimize evidence-based interventions.
The diagnosis and treatment of personality disorder are both highly contentious subjects. It is argued in this article that we have misunderstood personality pathology as yet another form of mental illness that should require treatment for its alleviation or removal. But it is not a typical mental illness; personality is a stable persistent component of the self and needs a different treatment approach based on adaptation.
To characterise hospital-treated multimorbidity patterns in people who subsequently died a drug-related death in Scotland, and to identify clinically meaningful associations among conditions and decedent to inform prevention and care.
Methods:
A register-based retrospective cohort study using nationally linked hospital admission (1996–2019) and mortality (2008–2019) records for 5,749 decedents. We identified hospital admissions for Elixhauser comorbidities using ICD-10 codes. Correlation analysis, network analysis, and Bayesian clustering were used to describe co-occurring conditions and identify patient clusters with distinct comorbidity profiles.
Results:
Over half (50.9%) of decedents had at least one admission for an Elixhauser comorbidity. The most frequent were related to alcohol use (38.2%), drug use (29.1%), other neurological disorders (18.0%, mainly epilepsy/seizures/anoxic brain injury), depression (15.2%), and psychoses (12.5%). Network analysis highlighted drug use, alcohol use, psychoses, depression, and neurological disorders as central conditions. Bayesian clustering identified seven distinct patient clusters, including groups characterised by: high psychiatric and drug-use admissions; extensive physical comorbidities; alcohol and liver disease; dominant neurological issues and depression.
Conclusions:
Individuals experiencing drug-related deaths exhibit substantial multimorbidity with distinct patterns often dominated by substance use and mental ill-health but also including significant physical health clusters. These distinct profiles underscore the need for integrated, tailored care strategies addressing substance use, psychiatric, and physical health needs to mitigate mortality risk.
“Dual disorders” (DD) refers to the co-occurrence of addiction and other mental health conditions, which often interact and complicate care. Despite scientific evidence showing shared brain mechanisms, current diagnostic systems treat them separately, leading to fragmented treatment and stigma. The World Association on Dual Disorders urges adopting “dual disorders” as a unified term to improve clarity, care integration, and outcomes.
The co-occurrence of mental illness and substance use disorders (SUDs) presents a significant public health challenge with affected individuals facing compounded stigma that leads to poor health outcomes, social exclusion, and systemic neglect. Despite growing recognition of stigma as a social determinant of health in people with comorbid mental illness and SUDs, current responses remain largely confined to clinical and academic settings. This article argues that civil society, particularly groups led by individuals with lived experience, represents an underutilized yet powerful force in combating stigma. Drawing from historical movements such as HIV/AIDS activism and contemporary examples from peer-led movements, we highlight how civil society organizations (CSOs) have reshaped public discourse, influenced policy, and fostered inclusive research. We examine emerging efforts in low resource settings and explore the transformative potential of digital civil society spaces. We advocate for a shift in stigma reduction paradigms to those that center lived experience, supports cross-sectoral collaboration, and recognizes both physical and digital civil society as essential to inclusive and sustainable change. To addressing the complex and intersecting stigmas associated with comorbid mental illness and SUDs, we recommend investing in CSOs, especially those grounded in participatory, culturally relevant approaches, particularly in low- and middle-income settings.
While prior studies have analyzed Skin Picking Disorder as a unitary condition, little research has been done examining clinical and neurocognitive characteristics of specific subtypes. The objective of this study is to analyze differences in impulsivity, emotional regulation, symptom severity, cognitive performance, and the presence of comorbid psychiatric conditions between focused and automatic subtypes of Skin Picking Disorder.
Methods
83 adults aged 18–65 with skin picking disorder were enrolled at the University of Chicago and separated into 4 skin picking subtype groups based on high or low levels of focused and automatic picking scores on the Milwaukee Inventory for the Dimension of Adult Skin Picking. The 4 subtype groups were separated using K-means clustering. Each group completed the same clinical and neurocognitive assessments. ANOVA or Chi-Squared tests were used to analyze differences in assessment outcomes.
Results
Higher focused picking scores were significantly associated with greater symptom severity and impairment. Differences in levels of automatic/focused picking were not associated with impulsivity, emotional/behavior regulations, or neurocognitive outcomes.
Conclusions
The findings suggest that focused skin pickers are likely to have more impairment due to their behavior compared to automatic or mixed pickers; however, overall, the groups did not differ in clinical or neurocognitive measures. Thus, it is unclear whether focused and automatic picking are particularly useful clinically in subtyping skin picking disorder.
Comorbid substance use and mental health disorders are highly prevalent and increase the risk of various adverse outcomes. Yet, treatment for comorbid substance use and mental health disorders is scattered and varies considerably between countries and regions. Quality standards are principles and sets of rules that can serve as a statement of expected requirements. They can be developed by (inter)national bodies and contribute to identification of shared ethical principles, harmonisation of care and implementation of evidence-based interventions. While in recent decades there has been an increase in the availability of quality standards in healthcare, and despite some national and regional efforts, international quality standards for the treatment of comorbid substance use and mental health disorders are lacking. Consensus over the development of such standards by international organisations could contribute to improved care for patients with comorbid substance use and mental health disorders globally.
Breast cancer is the most commonly diagnosed cancer worldwide. An estimated 1 in 7 women in the UK will receive a diagnosis during their lifetime, and up to 20% of people with breast cancer are treated with selective serotonin reuptake inhibitors (SSRIs). This comorbidity is a particularly important consideration for those co-prescribed hormonal cancer treatments. This article explores the complex relationship between breast cancer and mental illness, examining associations between hormonal breast cancer treatments, the premature menopause they can induce and SSRIs. It addresses prescribing considerations in this population, focusing on the co-prescribing of endocrine treatments such as tamoxifen and aromatase inhibitors with SSRIs and other psychotropic medications.
The aim of this study is to determine the prevalence and type of mental disorders associated with pathological gambling/gambling disorder (GD) in the general population.
Methods
Systematic review and meta-analysis of adult population-based studies reporting on psychiatric comorbidity of GD according to International Classification of Diseases (ICD-10/ICD-11), Diagnostic and Statistical Manual of Mental Disorders (DSM-IV/DSM-5) criteria, or widely used assessment instruments. PubMed, Scopus, and Web of Science databases were searched for relevant studies in English. The study’s protocol was preregistered in PROSPERO (CRD42024574210).
Results
Of 454 articles published between 1993 and 2024, 12 met the inclusion criteria. Most studies used DSM-IV or DSM-5 criteria (only two ICD-10 criteria), and were evenly distributed across Europe, North America, and Southeast Asia. The weighted average prevalence of any mental disorder in individuals with GD was 82.2%. High comorbidity rates were found for substance use disorders (SUDs) (34.2%), mood disorders (30.9%), and anxiety disorders (29.9%), followed by personality (14.3%) and psychotic (5.9%) disorders. Meta-analysis indicates that individuals with GD are 10.7 (95% confidence interval [CI]: 5.7;20.1) times more likely to develop any mental disorder than the general population. The odds ratio for mental disorders associated with GD were 5–12 times higher for nicotine dependence, drug use disorder, alcohol use disorder, and SUD, and 3–4 times higher for anxiety and mood disorders.
Conclusions
These findings add weight to the view that GD is associated with a significantly increased risk for addictive behaviors, mood, and anxiety disorders.
