Prenatal depression (PND) is a common psychiatric disorder in pregnant women and leads to psychosocial dysfunction, high suicidal rate, and adverse childcare. Patients with PND have omega-3 polyunsaturated fatty acid (omega-3 or n-3 PUFAs) deficits, which might link to chronic low-grade inflammatory process and the pathophysiological mechanisms of depression. In this case-control study, we examined the levels of PUFAs and inflammatory cytokines in PND. Blood samples were obtained and analyzed from 16 healthy controls and 17 depressed cases (PND group) diagnosed with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Independent sample t-test and correlation analysis were performed with Statistical Package for the Social Sciences (SPSS) logistics correlation analysis. PND group had significantly lower levels of total n-3 (p=0.026), docosahexaenoic acid (DHA) (p=0.020) and eicosapentaenoic (EPA) (p=0.019) but a higher omega-6 (n-6)/n-3 PUFAs ratio (p=0.007) and tumor necrosis factor alpha (TNF-α) (p=0.016) level. Moreover, the duration of current PND episodes were also significantly correlated with DHA, EPA, n-3 PUFAs, n-6/n-3 ratio and TNF-α. In terms of PUFAs and cytokine levels, only DHA was inversely correlated with TNF-α. PND is significantly associated with lower DHA, EPA, and total n-3 PUFAs levels and an increased n-6/n-3 PUFAs ratio, while the duration of PND is associated with lower levels of n-3 PUFAs, including DHA and EPA. The correlation of PUFAs levels with depression and TNF-α level grant further investigation into the inflammatory process underlying PND, mediated by PUFAs.

Numerous previous studies have shown the effectiveness of music therapy in enhancing cognitive functions in patients with dementia. Despite this, robust evidence in this field, especially concerning the comparison of different music therapy types, is lacking. Therefore, randomized controlled trials (RCTs) focusing on music therapy and cognitive functions in dementia patients, termed by “music” AND “dementia” OR “Alzheimer’s disease” AND “cognitive”, were identified from primary electronic databases to conduct this network meta-analysis (NMA). The primary outcome focused on the impact on cognitive functions, and the secondary outcome was the comparison of dropout rates between the intervention groups and the usual care control groups. Standardized mean difference (SMD) values and the corresponding 95% confidence intervals (CIs) were computed for effect evaluation. This study protocol has been registered in IPLASY (INPLASY202430082). A total of 14 RCTs with 1056 participants were enrolled, examining interventions including Active Music Therapy (AMT), Active Music Therapy with Singing (AMT + Sing), Rhythmic Music Therapy (RMT), Listening to Music (LtM), and Singing (Sing). The results indicated that RMT, AMT + Sing, and AMT all significantly improve cognitive functions in dementia patients, of which the SMD were 0.76 (95% CI = 0.32–1.21), 0.79 (95% CI = 0.03–1.49), and 0.57 (0.18–0.96), respectively. Compared with the control group (usual care), no music therapy type was associated with an increased dropout risk. In conclusion, music therapy can improve cognitive functions in patients with dementia without increasing the risk of dropout, particularly RMT, AMT + Sing, and AMT.

Major depressive episodes (MDEs) are common during pregnancy and postpartum periods, and the consequences can be severe to mother and offspring. Few studies have investigated the clinical factors associated with the onset and remission of perinatal depression in different time points. A cohort of 234 pregnant women was recruited and assessed with structured Mini-International Neuropsychiatric Interview (MINI) for diagnoses of MDEs. The severity of mood status was measured with Taiwanese version of the Edinburgh Postnatal Depression Scale (EPDS-T) and the second edition of Beck Depression Inventory (BDI-II) at 16 weeks' gestation, 28 weeks' gestation and 4 weeks postpartum. Statistical analysis was conducted by independent t-tests, chi-squared, and Fisher's exact tests. Thirty-one pregnant women (13.2%) developed MDEs; 11 (4.7%) at the 16th week, 8 (3.4%) at the 28th week of gestation, and 12 (5.1%) at the 4th week of postpartum. Among the 19 women with prenatal MDEs, 9 (47%) experienced remission by the end of pregnancy, and 10 sustained, resulting in the cumulative prevalence of 9.4% (22 out of 234) for postpartum MDEs. Women with lower levels of education, family history of psychiatric disorders, lack of postpartum recuperation, and family-bond stress were more likely to experience MDEs. More preterm birth and lower birth weights were reported in postpartum-onset than pregnancy-onset MDEs. Psychiatric interventions were associated with a higher percentage of remission of MDE during the perinatal period. The findings of this study provide clinical implications for early detection and intervention of MDEs throughout the pregnancy.

This study aims to assess the motivational factors influencing the participation of older adults in various exercise interventions during depressive episodes and to identify which types of exercise are most effective in alleviating depressive symptoms in this population. Therefore, randomized controlled trials (RCTs) focusing on exercise interventions and their impact on depression in older adult patients, identified by the terms “exercise” AND “depression” AND “elderly” OR “geriatric”, were selected from primary electronic databases to conduct this network meta-analysis (NMA). The primary outcome was the effect on depressive symptoms, while the secondary outcome was the comparison of dropout rates between the intervention groups and the usual care control groups, as a measure of sustained motivation and engagement. Standardized mean difference (SMD) values and the corresponding 95% confidence intervals (CIs) were computed for effect evaluation. This study protocol has been registered in IPLASY (INPLASY 202460035). The results of 31 RCTs with 3238 participants indicated that qigong (SMD −1.17, −2.28 to −0.06), Otago Exercise (SMD −1.15, −2.29 to −0.01), and yoga (SMD −0.88, −1.55 to −0.21) significantly alleviate depressive symptoms in older adults. Walking (SMD −0.82, −1.34 to −0.31) and strength training (SMD −0.67, −1.05 to −0.30) also showed significant effects. Aerobic, physical training, and tai chi had moderate effects, while multisport showed a weaker impact with no significant improvement. In summary, our research findings demonstrate that exercise can effectively alleviate depressive symptoms in older adults, with low dropout rates likely due to interconnected physiological, psychological, and social mechanisms. This is crucial for enhancing treatment strategies for older adults’ depression.
