Transcranial direct current stimulation (tDCS) is a promising treatment for major depressive disorder (MDD). This study evaluated its antidepressant and cognitive effects as a safe, effective, home-based therapy for MDD.

This double-blind, sham-controlled, randomized trial divided participants into low-intensity (1 mA, n = 47), high-intensity (2 mA, n = 49), and sham (n = 45) groups, receiving 42 daily tDCS sessions, including weekends and holidays, targeting the dorsolateral prefrontal cortex for 30 minutes. Assessments were conducted at baseline and weeks 2, 4, and 6. The primary outcome was cognitive improvement assessed by changes in total accuracy on the 2-back test from baseline to week 6. Secondary outcomes included changes in depressive symptoms (HAM-D), anxiety (HAM-A), and quality of life (QLES). Adverse events were monitored. This trial was registered with ClinicalTrials.gov (NCT04709952).

In the tDCS study, of 141 participants (102 [72.3%] women; mean age 35.7 years, standard deviation 12.7), 95 completed the trial. Mean changes in the total accuracy scores from baseline to week 6 were compared across the three groups using an F-test. Linear mixed-effects models examined the interaction of group and time. Results showed no significant differences among groups in cognitive or depressive outcomes at week 6. Active groups experienced more mild adverse events compared to sham but had similar rates of severe adverse events and dropout.

Home-based tDCS for MDD demonstrated no evidence of effectiveness but was safe and well-tolerated. Further research is needed to address the technical limitations, evaluate broader cognitive functions, and extend durations to evaluate its therapeutic potential.

Harmful alcohol consumption has significant cost on health and is associated with lower quality of life (e.g., Lu et al. BMC Public Health 2022; 22:789). In Singapore, a significant proportion of the adult population exhibit alcohol misuse behaviours (e.g., Lim et al. BMC Public Health 2013; 13:992). Many patients admitted into general hospitals have excessive alcohol consumption and related problems. These admissions can be an opportunity for intervention due to accessibility to the individuals and their time (Saitz et al. Ann Intern Med 2007; 146 167-176). Some studies have suggested that brief alcohol interventions (BAI) delivered in general hospitals can be effective in reducing alcohol use. However, there has been less support for the benefits of BAI on wellbeing.

This study investigated the effectiveness of BAI in improving perceived sense of wellbeing among male alcohol users admitted to a general hospital in Singapore.

108 male inpatients in various medical wards received BAI by the hospital’s addiction counsellors and completed the Personal Wellbeing Index (PWI) questionnaire. At a one-year follow-up via telephone, the PWI was again administered.

Average PWI scores were higher at follow-up (M = 7.83, SD = 1.16) than during baseline admission (M = 7.60, SD = 1.12), p < 0.01. Further analyses found that scores improved significantly on PWI items related to standard of living (M = 7.36, SD = 1.41 vs M = 7.09, SD = 1.65; p < 0.05), health (M = 7.42, SD = 1.74 vs M = 6.62, SD = 1.87; p < 0.01) and achievement (M = 7.43, SD = 1.44 vs M = 6.98, SD = 1.64; p < 0.01). There were no significant differences in scores on the other PWI items between baseline and follow-up.

Conclusions: The results suggest that BAI can be beneficial in improving patients’ sense of wellbeing.

Home nursing and medical services have an established role in delivering chronic medical care to populations which face difficulty accessing physical clinics. Those with chronic medical conditions and reduced mobility face a higher likelihood of suffering from psychiatric co-morbidity. However, till date there has been limited research done on home-based psychiatric care in this population.

Since 2021, the Psychiatry department of Tan Tock Seng Hospital (TTSH) has been collaborating with TTSH Community Health Team (CHT) to manage potential psychiatric issues in community patients.

These patients would be discussed in a weekly multidisciplinary setting. If indicated, home visit by both teams for home-based assessment and treatment would be arranged, allowing for detection and treatment of psychiatric illness.

To demonstrate that the collaboration between the psychiatry team and CHT leads to diagnosis and treatment of psychiatric illness in a population that might otherwise have been unable to access psychiatric services.

We performed a retrospective study on all referrals from the CHT to the psychiatry team, within the 2-year period of August 2021 to August 2023. We collected demographic information, psychiatric history prior to referral, reason for referral, outcome of multidisciplinary discussion, and outcome of the home visits (including diagnoses made, and medications initiated).

A total of 92 patients were referred by the CHT to the psychiatry team. Most were elderly with multiple medical co-morbidities; of note, a history of stroke was present in 24 of the referred patients.

Common reasons for referral include suspected mental illness, risk assessment, and management of behavioural issues.

28 of the referred patients did not have a prior psychiatric history at the point of referral. Among these, home visits involving the psychiatric team were done for 16 patients. 11 (68%) of these home visits led to diagnosis of a new psychiatric illness. 9 of these patients were initiated on psychotropic medications in the home setting.

A significant proportion of patients (68% of home visits without prior psychiatric diagnosis) were newly diagnosed with psychiatric illness, allowing early psychiatric intervention to be delivered. This was achieved in a population with a high prevalence of multiple medical comorbidity and barriers to clinic-based psychiatric evaluation and treatment.

We propose future comparative studies into how the collaboration between the psychiatric team and community health team can improve the quality of life and caregiver experience of patients with chronic medical problems, as well as how the service had improved the confidence of the community health team in identifying and managing patients with possible psychiatric issues.

Mental healthcare services that address a variety of primary complaints which are highly related to maladaptive personality traits among the general population are important to prevent developing psychiatric disorders.

This study aimed to examine the effectiveness of a digital mental health service (named “Mindling”) that focuses on maladaptive personality traits in the general population.

Participants were recruited through a South Korean community website and screened for adults between the ages of 18 and 60 in terms of personality traits such as perfectionism, low self-esteem, social isolation, or anxiety. Participants were allocated to four intervention programs (Riggy, Pleaser, Shelly, and Jumpy) based on their screening results and were randomly assigned to digital treatment and waitlist groups. Each intervention program was conducted online for 10 weeks. The primary outcomes were all measured by self-report questionnaires; in addition to stress levels, each program included measures of perfectionism (Riggy), low self-esteem (Pleaser), loneliness (Shelly), and anxiety (Jumpy). The secondary outcomes included self-efficacy, depression, and other psychological states. All participants completed pre-treatment (baseline), intervention (week 5), and post-treatment (week 10) assessments, and the treatment group completed a separate follow-up assessment (week 14).

In the treatment group, 70.05% of the participants completed the full course of the digital intervention. The mean scores for each primary outcome measure and some secondary outcome measures were significantly different between baseline and post-treatment in the treatment group for the Total, Riggy, Pleaser, Shelly, and Jumpy programs, but these differences were not observed in the waitlist group. In addition, mean differences between the treatment and waitlist groups at post-treatment assessment were significant for all primary outcome measures and some secondary outcome measures. Specifically, the levels of stress (Total program), perfectionism (Riggy), loneliness (Shelly), and anxiety (Jumpy) were significantly lower in the treatment group, while self-esteem (Pleaser) was higher. In addition, the mean differences between post-treatment and follow-up assessment data were not statistically significant for all primary outcome measures and nearly all secondary outcome measures.

This study validated the effectiveness of the digital intervention program targeting maladaptive personality traits and suggested its sustainable effects.

In recent years, rates of alcohol consumption and alcohol use disorder have steadily increased among adults age 60 and older. Large studies have demonstrated that moderate-to-heavy alcohol consumption (>7 drinks per week) is a risk factor for developing various types of dementias. The effects of alcohol-related problems on cognition are less clear, and are particularly understudied in older adults. Similarly, while there is an established link between worse cognition and financial exploitation vulnerability in older adults, no studies have examined relationships between alcohol-related problems and financial exploitation in this population. The current study therefore explores whether alcohol-related problems are associated with neuropsychological performance and financial exploitation vulnerability in a sample of older adults.

Participants were a community sample of cognitively unimpaired adults over the age of 50 (N = 55, Age M(SD) = 69.1(6.2), 74.5% female, Years of education M(SD) = 16.8(2.3)). Interested individuals were excluded if they reported current or past substance use disorders. Participants completed a laboratory visit that included a neuropsychological assessment. Measures included the NIH Cognition toolbox, CVLT-II, Digit Span, Trails A/B, Benson Complex Figure Recall, and Verbal Fluency: Phonemic and Semantic, from the Alzheimer’s Disease Centers’ Uniform Data Set (UDS) version 3. Participants completed the CAGE Alcohol Abuse Screening Tool and the Short Michigan Alcohol Screener Test - Geriatric Version (SMAST) to assess alcohol-related problems. Both measures are used as clinical screening tools to measure likelihood of a substance use disorder and produce a summary score (0-4 for CAGE, 010 for SMAST) tabulating symptoms of alcohol-related problems. Participants also completed the Perceived Financial Vulnerability Scale (PFVS) to assess financial exploitation vulnerability. As a significant number of participants reported no drinking and therefore no alcohol-related problems, negative binomial regressions were used to test associations between neuropsychological measures, financial exploitation vulnerability, and alcohol-related problems.

After covarying for age and sex, SMAST was negatively associated with NIH toolbox total cognition (B(SE) = -.14(.07), p<.05) and marginally negatively associated with fluid cognition (B(SE) = -.07(.04), p=.06). Neither SMAST nor CAGE scores were significantly associated with performance on any other neuropsychological test (ps = .13-.99). SMAST was positively associated with financial exploitation vulnerability (B(SE) = .31(.16), p = .05); this effect remained significant after covarying for NIH total composite score in a secondary analysis.

In a community sample of cognitively unimpaired, low-drinking adults over the age of 50, more alcohol-related problems were associated with worse NIH toolbox cognition scores. Similarly, more alcohol-related problems were associated with greater financial exploitation vulnerability, and this relationship was not driven by worse cognition. These results suggest that even low amounts of drinking and alcohol-related problems may be associated with cognition and financial exploitation vulnerability in cognitively unimpaired older adults. This study also corroborates the use of the SMAST over the CAGE in older adult populations that may be more sensitive to cognitive changes.

Prior work suggests financial exploitation vulnerability may be an early behavioral manifestation of Alzheimer’s disease (AD). Brain morphometric measures of the parahippocampal gyrus and entorhinal cortex have been shown to be sensitive to early AD progression. We hypothesized that perceived financial exploitation vulnerability may be associated with morphometric measures of the parahippocampal gyrus and entorhinal cortex in cognitively unimpaired older adults. We secondarily investigated the association of morphometric measures with neuropsychological measures.

The sample consisted of 39 cognitively unimpaired older adults (mean age = 68.74 ± 6.43, mean education = 16.87 ± 2.35, 77% female). Cognitive impairment was screened using the telephone version of the Montreal Cognitive Assessment (MoCA) and the cut-off was 21 for study participation. Perceived financial exploitation vulnerability was characterized using a 6-item self-report measure derived from the contextual items of the Lichtenberg Financial Rating Scale. Neuropsychological measures included the CVLT-II Long Delay Free Recall (verbal memory), Benson Complex Figure Recall (visual memory), and Verbal Fluency: Phonemic Test from the Alzheimer’s Disease Centers’ Uniform Data Set (UDS) version 3. Brain images were collected on a 7 Tesla Siemens Magnetom with the following parameters: TE=2.95ms, TR=2200ms, 240 sagittal slices, acquired voxel size (avs)=0.7mm x 0.7mm x 0.7mm. Structural brain images were processed using FreeSurfer version 7.2.0. Cortical thickness and volume measures were generated using the Killiany/Desikian parcellation atlas. Regions were averaged across hemispheres to obtain a single value for each region. Volume measures were adjusted for intracranial volume. Bivariate analyses were conducted to assess relationships between each outcome variable and potential confounders (age, sex, and education). Linear regression models were adjusted for any covariates significantly associated with the outcome variable (none for perceived financial exploitation vulnerability; sex and age for verbal memory; education for visual memory; sex for verbal fluency).

Smaller entorhinal cortex volume (β = -1275.14, SE = 582.79, p < 0.05) and lower parahippocampal gyrus thickness (β = -3.37, SE = 1.57, p < 0.05) were significantly associated with greater perceived financial exploitation vulnerability. Lower entorhinal cortex thickness was marginally associated with greater perceived financial exploitation vulnerability (β = -2.03, SE = 1.11, p = 0.08). Higher parahippocampal gyrus thickness was associated with better verbal fluency (β = 17.66, SE = 7.01, p < 0.05). Higher entorhinal cortex thickness was associated with better visual memory (β = 4.71, SE = 1.73, p < 0.05). No significant associations were observed between structural brain measures and verbal memory.

These results suggest smaller entorhinal cortex volume and lower parahippocampal gyrus thickness are associated with higher perceived financial exploitation vulnerability in cognitively normal older adults. Additionally, parahippocampal gyrus thickness appears to be associated with verbal fluency abilities while entorhinal cortex thickness appears to be associated with visual memory. Taken together, these findings lend support to the notion that financial exploitation vulnerability may serve as an early behavioral manifestation of preclinical AD. Longitudinal studies are needed to better understand the temporal nature of these relationships.

Sinonasal inverted papilloma has a high tendency for recurrence, local bone destruction and risk of malignant transformation. Therefore, complete resection of the tumour is required, and close follow up is essential. This article describes the clinical outcomes, recurrence rate and malignant transformation rate of sinonasal inverted papilloma.

In this study, 139 patients diagnosed with sinonasal inverted papilloma in our hospital from December 2010 to May 2022 were retrospectively analysed. All patients underwent endoscopic surgery.

Sinonasal inverted papilloma occurred more often in males than in females. The mean age of patients with sinonasal inverted papilloma was 67.3 ± 5.7 years at diagnosis. The most prevalent site of origin was the maxillary sinus (50.4 per cent). The recurrence rate was 5.75 per cent, and the malignant transformation rate was 6.5 per cent.

All patients in this study underwent endoscopic surgery. Meticulous resection and regular long-term follow ups are crucial to reducing sinonasal inverted papilloma recurrence after surgery.

To study the safety and efficacy of Artiss fibrin sealant in lateral neck dissection, focusing on drain retention time, length of hospital stay and post-operative complications.

A retrospective review was conducted of patients who underwent neck dissection in a UK hospital over a 12-month period.

Twenty-three patients were identified; 13 patients had Artiss and a drain, 10 patients had Artiss only. All drains were removed by post-operative day 2. No post-operative fluid collections or complications were recorded. Patients who had Artiss only without a drain were discharged on post-operative day 1.

The use of Artiss reduced the drain retention time and hospital stay, with no post-operative complications. Neck dissection can be safely undertaken with no drain, and can potentially be carried out as a day-case procedure, with the application of Artiss. These findings benefit patients and the National Health Service by improving the patient journey and reducing overall costs.

To analyse the treatment results of bilobed flap reconstruction performed for skin defects after parotid carcinoma surgery.

Ten patients who underwent bilobed flap reconstruction for skin defects after parotid carcinoma surgery in our hospital, from 2014 to 2020, were retrospectively enrolled.

All patients underwent bilobed flap reconstruction for skin defects after parotid carcinoma surgery. The size of the skin defect was 2.7 × 2.2 cm in the smallest dimension and 9.0 × 6.3 cm in the largest dimension. All bilobed flaps except one healed without any problems. One patient developed partial flap necrosis in the retroauricular region, and was treated with skin grafts after removal of the necrotic tissue under local anaesthesia. All bilobed flaps, including the cases in which skin grafts were performed, survived after post-operative radiotherapy or chemotherapy.

A bilobed flap is a good reconstruction option for skin defects after parotid carcinoma surgery in some cases.

This study aimed to analyse the results of chyle fistula testing using the SD LipidoCare system in patients who had undergone neck dissections performed in our hospital in 2019.

Sixty patients who underwent neck dissections from March 2019 to November 2019 were identified based on their medical records.

Post-operative chyle fistulas were observed in 3 of 60 patients (5 per cent). All patients who developed chyle fistulas had undergone left-sided neck dissections. Within 3 minutes, the SD LipidoCare test had produced triglyceride results of 49, 56 and 207 mg/dl in the three patients. The remaining 57 patients measured ‘low’ for triglycerides on the SD LipidoCare test system.

The SD LipidoCare test quickly and accurately diagnosed chyle fistulas in patients who had undergone neck dissections. All patients improved with conservative treatment following the early diagnosis of chyle fistulas.

The coronavirus disease 2019 (COVID-19) pandemic has led to significant strain on front-line healthcare workers.

In this multicentre study, we compared the psychological outcomes during the COVID-19 pandemic in various countries in the Asia-Pacific region and identified factors associated with adverse psychological outcomes.

From 29 April to 4 June 2020, the study recruited healthcare workers from major healthcare institutions in five countries in the Asia-Pacific region. A self-administrated survey that collected information on prior medical conditions, presence of symptoms, and scores on the Depression Anxiety Stress Scales and the Impact of Events Scale-Revised were used. The prevalence of depression, anxiety, stress and post-traumatic stress disorder (PTSD) relating to COVID-19 was compared, and multivariable logistic regression identified independent factors associated with adverse psychological outcomes within each country.

A total of 1146 participants from India, Indonesia, Singapore, Malaysia and Vietnam were studied. Despite having the lowest volume of cases, Vietnam displayed the highest prevalence of PTSD. In contrast, Singapore reported the highest case volume, but had a lower prevalence of depression and anxiety. In the multivariable analysis, we found that non-medically trained personnel, the presence of physical symptoms and presence of prior medical conditions were independent predictors across the participating countries.

This study highlights that the varied prevalence of psychological adversity among healthcare workers is independent of the burden of COVID-19 cases within each country. Early psychological interventions may be beneficial for the vulnerable groups of healthcare workers with presence of physical symptoms, prior medical conditions and those who are not medically trained.

To identify and synthesise the literature on the cost of mental disorders.

Systematic literature searches were conducted in the databases PubMed, EMBASE, Web of Science, EconLit, NHS York Database and PsychInfo using key terms for cost and mental disorders. Searches were restricted to January 1980–May 2019. The inclusion criteria were: (1) cost-of-illness studies or cost-analyses; (2) diagnosis of at least one mental disorder; (3) study population based on the general population; (4) outcome in monetary units. The systematic review was preregistered on PROSPERO (ID: CRD42019127783).

In total, 13 579 potential titles and abstracts were screened and 439 full-text articles were evaluated by two independent reviewers. Of these, 112 articles were included from the systematic searches and 31 additional articles from snowball searching, resulting in 143 included articles. Data were available from 48 countries and categorised according to nine mental disorder groups. The quality of the studies varied widely and there was a lack of studies from low- and middle-income countries and for certain types of mental disorders (e.g. intellectual disabilities and eating disorders). Our study showed that certain groups of mental disorders are more costly than others and that these rankings are relatively stable between countries.

This is the first study to provide a comprehensive overview of the cost of mental disorders worldwide.

The existing literature on chronic pain points to the effects anxiety sensitivity, pain hypervigilance, and pain catastrophizing on pain-related fear; however, the nature of the relationships remains unclear. The three dispositional factors may affect one another in the prediction of pain adjustment outcomes. The addition of one disposition may increase the association between another disposition and outcomes, a consequence known as suppressor effects in statistical terms.

This study examined the possible statistical suppressor effects of anxiety sensitivity, pain hypervigilance and pain catastrophizing in predicting pain-related fear and adjustment outcomes (disability and depression).

Chinese patients with chronic musculoskeletal pain (n = 401) completed a battery of assessments on pain intensity, depression, anxiety sensitivity, pain vigilance, pain catastrophizing, and pain-related fear. Multiple regression analyses assessed the mediating/moderating role of pain hypervigilance. Structural equation modeling (SEM) was used to evaluate suppression effects.

Our results evidenced pain hypervigilance mediated the effects of anxiety sensitivity (Model 1: Sobel z = 4.86) and pain catastrophizing (Model 3: Sobel z = 5.08) on pain-related fear. Net suppression effect of pain catastrophizing on anxiety sensitivity was found in SEM where both anxiety sensitivity and pain catastrophizing were included in the same full model to predict disability (Model 9: CFI = 0.95) and depression (Model 10: CFI = 0.93) (all P < 0.001) (see Figs. 3 and 4, Figs. 1 and 2).

Our findings evidenced that pain hypervigilance mediated the relationship of two dispositional factors, pain catastrophic cognition and anxiety sensitivity, with pain-related fear. The net suppression effects of pain catastrophizing suggest that anxiety sensitivity enhanced the effect of pain catastrophic cognition on pain hypervigilance.

This research aimed to identify the effects of depressive mood of female high school students on dysmenorrhea and sleep quality.

This research was conducted for 2 months from September 2015 to October 2015. A total of 3 types of self-reported questionnaire were adopted for the research. Control group was separated by Zung Self-rating Depression Scale (ZSDS). Each group adopted a self-made questionnaire for research on menstruation and Pittsburgh Sleep Quality Index (PSQI) for research on sleep. Chi2 test and AVOVA analysis through SPSS-21 were used as statistics methods.

Analysis was made on 72 female students who submitted clear answers to the questionnaire. There were 34 students from normal mood group and 38 from depressive mood group. Depressive group presented meaningful results on regularity, pain severity, and drug treatment history of menstruation. Particularly, depressive group had 51.4% among subjects having severe menstrual pain of grade 3 by VMS (verbal multidimensional scoring system), way higher than 27.6% among subjects in the normal group. PSQI for sleep showed a meaningful result that 20.8% of those in the normal group were diagnosed with sleep disorder compared to 86.8% for the depressive group. A meaningful difference was seen in sleep latency, sleep duration, sleep disturbance, use of sleep medication, daytime functional disturbance among 7 items of PSQI.

This research showed that female high school students with depressive mood had high frequency and severity in dysmenorrhea and sleep quality disturbance.
