Clinical course and treatment interventions for adolescents who vaped during the COVID-19 pandemic.

Vaping nicotine and marijuana have been increasing among adolescents in the past 5 years. Tetrahydrocannabinol is the psychoactive cannabinoid in marijuana. The COVID-19 pandemic created gaps in healthcare access and visits, making it difficult to collect accurate data on adolescent vaping, willingness to quit and methods used to quit. In addition, the literature lacks information regarding effective evidence-based treatment measures for adolescents who vape. In this report, we seek to address this using two patient cases and detailing the interventions a managed care organisation enacted during this timeframe. Our investigation revealed a relationship between social stressors and vaping among teens. Addressing these underlying stressors and eliciting and treating mental health symptoms and polysubstance use appears to be critical to curbing vaping.

Abortion Is a Right: Perspectives of Family Medicine Physician Residents.

Abortion is healthcare. Bodily autonomy is a fundamental human right. As chief resident physicians representing family medicine residency programs in the Greater Bay Area and Central California in the University of California San Francisco Family Medicine Alliance, we share a deep commitment to promoting health equity, advancing social justice, and eliminating health disparities. The 2022 Supreme Court decision in Dobbs v. Jackson Women's Health Organization to overturn Roe v. Wade contradicts the inherent rights of patients to make their own reproductive healthcare decisions. This is a clarion call for all people to engage in activities to raise awareness and prompt discussion about abortion, reproductive rights, and maternal mortality.

Quality Improvement Approach to Increasing Psychiatric Rehabilitation in the Inpatient Setting.

This clinical practice improvement project (CPIP) sought to increase the rate of referrals to psychiatric rehabilitation units among inpatients on a 44-bed men's ward at the Institute of Mental Health, Singapore. Three root causes of low referral rates were targeted for intervention, and three plan-do-study-act cycles were conducted to address these causes. Interrupted time-series analysis was used to assess the impact of the interventions. Addressing these causes significantly and sustainably improved the rate of referral. The rate of rehabilitation program attrition did not worsen because of the increased number of referrals. These findings indicate that CPIPs can significantly improve processes.

The effects of axial loading on the morphometric and T2 characteristics of lumbar discs in relation to disc degeneration.

BACKGROUND: Intervertebral disc degeneration affects the morphology, biomechanics and biochemistry of the disc. The study aimed to compare the effects of compression and traction on lumbar discs measurements in relation to degeneration. METHODS: Thirty-five volunteers (30 (SD 11) yrs.) with and without chronic back pain rested supine 15 min before an unloaded T2-mapping MRI, were then loaded 20 min with 50% body weight with imaging during the last 5 min, and then repeated this process under traction. For lumbar discs, height, angle, width, mean-T2, and T2-weighted centroid locations were calculated. A repeated measure ANCOVA and Cohen's d compared loading conditions. Relations between measurement changes between conditions and degeneration assessed by Pfirrmann ratings were examined graphically. FINDINGS: From compression to traction, we observed significant: decrease in L1-2 mean-T2 (Effect size = -0.35); inferior and posterior shift in L4-5 (0.4, 0.14) and L5-S1 (0.25, 0.33) T2-weighted centroid. From unloaded to compression, we observed a significant: increase in L5-S1 width (Effect Size = 0.22); anterior shift in L1-2 T2-weighted centroid (0.39); and L3-4 (mean 2.1°) and L4-5 (1.8°) extension angle. More degeneration was graphically related with larger changes from Compression to Traction (more superior and, anterior position of the T2-weighted centroid, increased height, reduced extension of segmental angle) and from Unloaded to Compression larger changes in inferior displacement of the T2-weighted centroid, decrease in height) but less anterior displacement of the centroid and less change in segmental angles. INTERPRETATION: The largest loading responses were at lower levels, generally with more degeneration. T2-weighted centroid locations, angle and disc height detected the largest loading response.

The personal recovery movement in Singapore - past, present and future.

The personal recovery movement is beginning to gain traction within Singapore's mental healthcare systems. We believe it is timely to give a broad overview of how it developed and provide suggestions on how it can evolve further. From the early custodial care in the 1800s to the community-centric programmes of the 1900s and early 2000s, we now find ourselves at the forefront of yet another paradigm shift towards a more consumer-centric model of care. The following decades will allow personal recovery practitioners and researchers to innovate and identify unique but culturally appropriate care frameworks. We also discuss how the movement can continue to complement existing mental healthcare systems and efforts.

Stakeholder perspective on barrier to the implementation of Advance Care Planning in a traditionally paternalistic healthcare system.

BACKGROUND: Advance psychiatric agreements could guide medical teams in providing care consistent with the incapacitated service user's wishes. However, these types of agreements are rarely completed in Asian settings. What challenges can a traditionally paternalistic healthcare system expect to encounter when attempting to implement psychiatric advance directives? METHODS: We answered this research question by exploring the cultural, administrative and logistical challenges that might impede the implementation of the system supporting the service. We interviewed key stakeholders, 28 service users and 22 service providers, to seek their views and interests in the implementation of directives. We structured our analyses along a literature-review-based framework designed to guide further implementation studies, proposed by Nicaise and colleagues (2013). Accordingly, we divided our inductively generated themes into four longitudinal categories: pre-development stage, development stage, implementation stage, post-implementation stage. RESULTS: Overall, the findings indicated that many service users and service providers are interested in advance care planning. They believed that foreseeable challenges could be overcome with appropriate measures. However, the multiple challenges of implementation led some service providers to be ambivalent about their implementation and led service users to dismiss them. Specifically, factors related to the local culture in Singapore necessitated adjustments to the content and structure of the directives. These include language barriers in a multicultural society, conflicting wishes in a collectivist society, taboos for speaking about undesirable outcomes in a traditionalist society, and time limitations in a fast-paced society. CONCLUSION: While culture-specific changes may be required to enable service users in a small Asian country to employ existing advance psychiatric agreement approaches, service providers and service users see their benefits. However, service providers must be mindful not to assume that service users are willing to defer every decision to their physician.

Could compression and traction loading improve the ability of magnetic resonance imaging to identify findings related to low back pain?

BACKGROUND: Diagnostic imaging is routinely used to depict structural abnormalities in people with low back pain (LBP), but most findings are prevalent in people with and without LBP. It has been suggested that LBP is related to changes induced in the spine due to loading. Therefore, new imaging measurements are needed to improve our ability to identify structures relating to LBP. OBJECTIVES: To investigate the response of the lumbar spine to compression and traction in participants with and without chronic LBP using MRI T2-mapping. METHOD: Fifteen participants with chronic LBP were matched for age, weight, and gender with 15 healthy volunteers. All participants underwent MRI under three loading conditions maintained for 20 min each: resting supine, followed by compression and traction, both using 50% body weight. Participants were imaged in the last 5 min of each loading condition. Disc morphometric and fluid-based measurements from T2-maps were obtained. RESULTS: Traditional MRI measurements (i.e. disc height, width and mean signal intensity) were not able to capture any differences in the changes measured in response to loading between individuals with and without pain. The location of the T2 weighted centroid (WC) was able to capture the difference between groups in response to compression in the horizontal (p < 0.01) and vertical direction (p < 0.01), and in response to traction in the vertical direction (p < 0.01). While the location of T2WC moved anteriorly (Effect Size (ES): 0.44) and inferiorly with compression in those with pain (ES: 0.34), it moved posteriorly (ES: -0.14) and superiorly (ES: -0.05) in the group without pain. In response to traction, the vertical location of T2WC moved superiorly in both groups but the change was larger in those with pain (ES Pain = -0.52; ES No Pain: -0.13). CONCLUSION: The novel measurements of the location of the T2WC in the intervertebral discs were the only measurements capturing differences in response to loading between those with and without low back pain.

Vitamin D deficiency in long-term hospitalization psychiatric wards in an equatorial nation.

INTRODUCTION: Vitamin D deficiency and insufficiency have been shown to be prevalent in several populations, including in people who have a mental illness. Deficiency has been linked to specific mental health sequelae. Furthermore, deficiency may be perpetuated by medications routinely prescribed to people with severe mental illness. Therefore, symptoms of mental illness may be exacerbated by deficient levels of vitamin D, and treatments for mental illness may exacerbate deficiency. This study sought to determine the vitamin D levels of people hospitalized for a period longer than a year in an equatorial nation, Singapore. The inpatient population was then categorized according to levels to determine the need for supplementation. METHODS: Total 25-hydroxy vitamin D in serum and plasma levels were tested in 403 individuals in long-term psychiatric wards. Blood serum and plasma levels were classified into three groups. Regression models were constructed to test the associations between levels and clinical covariates. RESULTS: Forty (9.9%) people had vitamin D levels that were sufficient. A link was found between vitamin D levels and medications given for gastrointestinal illnesses (ß -2.48, p = .014, 95%CI -4.46 to-0.51) and between vitamin D levels and length of stay (ß -0.13, p = .027, 95%CI -0.24 to-0.01). No other relationships were statistically significant. DISCUSSION: Despite its geographic location and opportunities for regular outdoor activity, vitamin D deficiency, and insufficiency are prevalent among people hospitalized for long periods of time in an equatorial nation. The level of deficiency is comparable to those observed in other settings.

Psychiatric Advance Directives and their relevance to improving psychiatric care in Asian countries.

People with mental illness may be unable to provide critical input about the care they wish to receive during a psychiatric crisis because of altered mental states. It is therefore imperative that clinicians seek to understand service users' wishes for care while they are well and able to provide meaningful input into the discussion. Achieving such an end may be done by discussing and completing a psychiatric advance directive. However, very few Asian countries have legislation that supports such advance directives. The present article seeks to give physicians more information about advance psychiatric directives and the potential role they could play to improve the healthcare provided in Asia to people at risk of losing capacity due to a mental illness. The degree to which mental health legislation supports psychiatric advance directives is documented for each country of South East Asia and Eastern Asia.

An Outbreak of Streptococcus pyogenes in a Mental Health Facility: Advantage of Well-Timed Whole-Genome Sequencing Over emm Typing.

OBJECTIVEWe report the utility of whole-genome sequencing (WGS) conducted in a clinically relevant time frame (ie, sufficient for guiding management decision), in managing a Streptococcus pyogenes outbreak, and present a comparison of its performance with emm typing.SETTINGA 2,000-bed tertiary-care psychiatric hospital.METHODSActive surveillance was conducted to identify new cases of S. pyogenes. WGS guided targeted epidemiological investigations, and infection control measures were implemented. Single-nucleotide polymorphism (SNP)-based genome phylogeny, emm typing, and multilocus sequence typing (MLST) were performed. We compared the ability of WGS and emm typing to correctly identify person-to-person transmission and to guide the management of the outbreak.RESULTSThe study included 204 patients and 152 staff. We identified 35 patients and 2 staff members with S. pyogenes. WGS revealed polyclonal S. pyogenes infections with 3 genetically distinct phylogenetic clusters (C1-C3). Cluster C1 isolates were all emm type 4, sequence type 915 and had pairwise SNP differences of 0-5, which suggested recent person-to-person transmissions. Epidemiological investigation revealed that cluster C1 was mediated by dermal colonization and transmission of S. pyogenes in a male residential ward. Clusters C2 and C3 were genomically diverse, with pairwise SNP differences of 21-45 and 26-58, and emm 11 and mostly emm120, respectively. Clusters C2 and C3, which may have been considered person-to-person transmissions by emm typing, were shown by WGS to be unlikely by integrating pairwise SNP differences with epidemiology.CONCLUSIONSWGS had higher resolution than emm typing in identifying clusters with recent and ongoing person-to-person transmissions, which allowed implementation of targeted intervention to control the outbreak.Infect Control Hosp Epidemiol 2018;852-860.

The 23-Hour Observation Unit Admissions Within the Emergency Service at a National Tertiary Psychiatric Hospital: Clarifying Clinical Profiles, Outcomes, and Predictors of Subsequent Hospitalization.

OBJECTIVE: We examined health care utilization, clinical profiles (such as sociodemographic features, clinical severity), and outcomes (inpatient admission, revisit within 24 hours of discharge) of patients who were admitted to a 23-hour observation unit within the emergency service of a tertiary psychiatric hospital and hypothesized that a specific clinical profile (greater clinical severity, lower psychosocial functioning) predicted subsequent inpatient hospitalization. METHOD: The medical records of all patients admitted to the observation unit from February 5, 2007, to February 4, 2012 (N = 2,158) were assessed for relevant data. Clinical severity and level of psychosocial functioning were assessed using Clinical Global Impressions-Severity (CGI-S) and Global Assessment of Functioning (GAF) scales, respectively. RESULTS: Overall, the patients seen were predominantly Chinese males > 36 years old who had diagnoses including stress-related, anxiety, affective spectrum, and psychotic disorders. The clinical severity score (CGI-S) improved significantly following discharge from the observation unit (t 1,1848 = 23.316; P < .001). Logistic regression analyses revealed that self-referred (P = .001), older patients (P = .007) with past psychiatric history (P = .019), lower GAF scores (P = .025), and less improvement of CGI-S scores (P = .001) were associated with inpatient admission after a 23-hour stay in the observation unit. CONCLUSIONS: Our study findings affirmed our hypothesis and supported the utility of the observation unit in monitoring the overall clinical status of patients, which was linked with subsequent inpatient admissions. Better management of these patients at the outpatient level can potentially decrease unnecessary hospitalization and reduce health care cost as well as illness burden on patients and caregivers.

Safety and efficacy of long-acting injectable risperidone in patients with schizophrenia spectrum disorders: a 6-month open-label trial in Asian patients.

The study aimed to evaluate the efficacy of long-acting injectable risperidone (LAR) in Asian patients with schizophrenia spectrum disorders. Twenty-five patients enrolled in this 6-month open labelled study. They were switched from their current antipsychotic to LAR without a prior oral risperidone run-in phase. Efficacy was assessed by the positive and negative syndrome scale (PANSS) and clinical global impression (CGI) scales. Extra-pyramidal side effects (EPSE) was assessed using the Simpson Angus Scale (SAS), and weight and plasma levels of fasting blood glucose, lipids and prolactin were measured. Baseline and last visits differences were tested by paired t-test and Wilcoxon signed-rank test; ratings measured over time were analysed using repeated measures ANOVA. Participants' mean age was 30.3 (+/-6.6) years. Principal reason for switching to LAR was non-compliance (40.0%). Thirteen (52%) patients completed the trial. Over 6 months, there were significant reductions in total PANSS (p = 0.008) and CGI (p = 0.001) scores. There were significant increases in weight (p < 0.001), levels of plasma cholesterol and fasting glucose. LAR was effective in improving symptom severity within the first month of starting treatment. However, significant increases in weight and plasma levels of fasting glucose and cholesterol raise concern about metabolic side effects.

Suicide in psychiatric patients: case-control study in Singapore.

OBJECTIVE: Persons with psychiatric illness, especially depression and schizophrenia, are at relatively high risk of suicide, but there are few studies that look at the Asian population. The aim of the present study was to identify the risk period and risk factors for suicide in psychiatric patients in Singapore. The nature of psychiatric care that was provided, both inpatient and outpatient, was also explored. METHOD: This is a case-control study of 123 patients who committed suicide from 2003 to 2004. Controls were 123 surviving patients who were individually matched for age, gender, principal diagnosis and calendar time. RESULTS: The most common principal diagnoses among the suicide subjects were schizophrenia (46.3%) and depression (26.8%). Numerous factors were associated with significantly increased suicide risk. Stepwise conditional logistic regression showed that the following three independent factors best predicted suicide: history of attempted suicide using highly lethal means; coexisting significant physical illness; and delusions. Suicides occur mainly soon after discharge and after an outpatient consult. Subgroup analyses were done to distinguish between subjects who suicided early and late following discharge. CONCLUSIONS: Suicidal risk remains high in Singaporean psychiatric patients soon after discharge. They share some common risk factors for suicide identified in Western studies but the lower prevalence of substance abuse and comorbidity in Singaporean suicide subjects was one notable difference. The phenomena of suicides soon after discharge and outpatient review suggest the need for proper identification and more intensive follow up during this period.

Antipsychotic polypharmacy in patients with schizophrenia: a multicentre comparative study in East Asia.

AIMS: Previous studies of the prescription patterns of psychotropic medications in patients with schizophrenia have highlighted a high rate of antipsychotic polypharmacy, but data in Asia are sparse. This study seeks to examine the prevalence of antipsychotic polypharmacy in patients with schizophrenia and compare the differences between patients receiving one vs. those receiving more than one antipsychotic. METHODS: Antipsychotic prescription for a sample of 2399 patients with schizophrenia from six countries and territories was evaluated. Daily doses of antipsychotic medications were converted to standard chlorpromazine equivalents (CPZ). RESULTS: Antipsychotic polypharmacy was found in 45.7% (n = 1097) of the patients with wide intercountry variations. Polypharmacy was associated with male gender [odds ratio (OR) 1.24, 95% confidence interval (CI) 1.06, 1.46, P < 0.01], advanced age (t = -7.81, d.f. = 2396, P < 0.001), psychiatric hospital setting (OR 1.34, 95% CI 1.11, 1.62) as well as higher daily CPZeq doses (411.47 vs. 983.10 CPZeq day(-1), z = -25.94, P < 0.001), anticholinergic use (OR 3.17, 95% CI 2.65, 3.79, P < 0.001) and less use of an atypical antipsychotic drug (OR 0.83, 95% CI 0.71, 0.98, P < 0.05). On multivariate analysis, country, age and duration of illness were significantly associated with antipsychotic polypharmacy. CONCLUSION: This study highlighted the wide intercountry variations of antipsychotic polypharmacy which are likely to be influenced by a complex combination of clinical, setting, cultural and personal practice factors, requiring more research.

Clinical correlates of antipsychotic polytherapy in patients with schizophrenia in Singapore.

The purpose of the present study wa to determine the prevalence of antipsychotic polytherapy (use of more than one antipsychotic drug at one time) and its clinical correlates among 300 hospitalized psychotic Asian patients diagnosed with schizophrenia. It was hypothesized that such treatment would be associated with more severe illness than in comparable monotherapy patients, and with higher chlorpromazine-equivalent (CPZ) total daily doses. Clinical and demographic details were obtained from the medical records and direct clinical examinations. Polytherapy was encountered in 215 of the 300 patients (71.7%), with an average number of 1.8 antipsychotics (range 1-4) prescribed at a mean CPZ daily dose of 612 +/- 528 mg (median: 464 mg, range: 25-2500 mg). The 215 patients prescribed more than one antipsychotic agents were younger, ill longer, more likely to be taking at least one high-potency agent, in receipt of higher average daily CPZ doses, and more likely to be prescribed anticholinergic agents but with similar admission illness severity rating (Brief Psychiatric Rating Scale) scores compared to the 85 patients given only one antipsychotic drug at one time. The high rate of antipsychotic polytherapy that appeared to be unrelated to current illness severity suggests that this practice may not consistently be based on rational therapeutic principles.

Depot antipsychotic use in schizophrenia: an East Asian perspective.

AIMS: Few studies have examined the use of depot antipsychotics in East Asian patients with schizophrenia. This study examined the prevalence of depot antipsychotic use and its clinical correlates. METHODS: Across six East Asian countries and territories, 2399 patients with schizophrenia were surveyed using a standardized protocol. RESULTS: Depot antipsychotic medications were prescribed in 15.3% (n=368) of the patients, being the most common in Singapore, followed by Taiwan, Japan and China. Being on depot antipsychotic drugs was significantly associated with male gender (particularly in Taiwan and Japan), delusions in Japan, aggression, higher daily CPZ equivalent dose and co-prescription of anticholinergic drugs but less likely with disorganized speech (particularly in China) and negative symptoms (particularly in Japan and Singapore). On multivariate analysis, the significant associated factors were treatment setting, younger age, longer duration of illness, aggression and the lack of use of an oral, atypical antipsychotic. CONCLUSION: There was a wide variation in the prevalence of depot antipsychotic prescription, suggesting that it may not be guided by any recognizable principles and is more likely determined by local traditions and prescription culture. There is a need to re-examine the risk-benefit profile of each patient before deciding on the initiation or continuation of depot antipsychotic medication.

Personality profiles of patients with dissociative trance disorder in Singapore.

This report studies the personality of individuals who suffer from dissociative trance disorder and examines whether the personality profiles could predict the individual's frequency of trance states. A total of 58 cases were given the Eysenck Personality Questionnaire (EPQ) and their personal information harvested from the case notes and through subsequent interviews. The subjects were also reassessed 1 year later to obtain their frequency of trance states. For both sexes, there were lower extraversion scores and higher psychoticism, neuroticism, and lie scores in the sample compared to the Singapore norms. Of the 47 subjects traced, total episodes of trances that occurred over the 1-year period was positively correlated with neuroticism and negatively with extraversion scores. The high lie scores in individuals with dissociative trance disorder could be a reflection of their concern of how others perceive them. The motivation could be that of restoration of self-esteem or "face." The profiles in the EPQ could be used to predict the individual's frequency of trance states. Subjects with personality traits like nervousness, excitability, and emotional instability were more likely to have a higher frequency of trance states.
