Borrelia miyamotoi is a tick-borne spirochete of the relapsing fever borrelia group and an emerging pathogen of public health significance. The genomes of relapsing fever borreliae and Lyme disease borreliae consist of multiple linear and circular plasmids in addition to the chromosome. Previous work with B. burgdorferi sensu lato found diminished infectivity upon continuous in vitro culture passage that was attributable to plasmid loss. The effect of long-term culture passage on B. #link# miyamotoi is not known. We generated a series of plasmid-specific primer sets and developed a multiplex PCR assay to detect the 14 known plasmids of B. miyamotoi North American strains LB-2001 and CT13-2396. We assessed the plasmid content of B. miyamotoi LB-2001 over 64 culture passages spanning 15 months and determined that strain LB-2001 retained all plasmids upon prolonged in vitro cultivation and remained infectious in mice. We also found that strain LB-2001 lacks plasmid lp20-1 which is present in strain CT13-2396. These results suggest that B. miyamotoi remains genetically stable when cultured and passaged in vitro.Though ticks pose a significant public health risk, until recently, little research had focused on the diversity of ticks and tick-borne diseases in Singapore. To date, only fourteen tick species in five genera have been recorded there. For the first time, Dermacentor auratus is recorded from Singapore from a range of hosts, including humans. DNA sequences are provided at 2 loci, for D. auratus, the cytochrome c oxidase I (COI) for DNA barcoding and the 16S large subunit ribosomal RNA (16S lsu rRNA). The health risk posed by D. auratus in Singapore is discussed.
Differences in risk and protective factors (e.g., victimization, abuse, social support) have been used to explain elevated rates of suicidal ideation and suicide attempts in sexual minority youth (SMY) relative to heterosexual peers. However, little is known regarding how risk and protective factors may explain suicide risk differences among subgroups of SMY. The aims of this study were to 1) examine differences in prevalence and severity for suicide risk and protective factors among SMY, and 2) explore whether risk and protective factors are differentially associated with suicidal ideation and suicide attempts for SMY subgroups.

Participants were 6,423 adolescents (ages 12-17) recruited from 14 Emergency Departments across the United States who completed an assessment of suicide risk and protective factors. SMY were 20% of the sample (n=1,275) and categorized as bisexual (8%), gay/lesbian (2%), mostly straight (5%), or other sexual minority (5%).

Bisexual youth had elevated rates of suicidal ideation and attempts, more risk factors (e.g., bullying victimization, depression), and fewer protective factors (e.g., parent-family connectedness, positive affect) relative to mostly straight and other sexual minority youth. Bisexual and gay/lesbian youth only differed in parent-family connectedness (lower among bisexual youth). Depression and parent-family connectedness had weaker associations with suicidal ideation for bisexual youth.

Emergency departments were not nationally representative. Study design was cross-sectional, preventing causal inferences.

Interventions seeking to mitigate risk factors and promote protective factors are greatly needed for SMY and may benefit from tailoring to address unique stressors for sexual minority subgroups.

Previous research suggests that comorbid personality disorder may be associated with a less favourable treatment outcome for individuals with depression and anxiety disorder. However, little is known about whether personality difficulties are associated with treatment outcomes within Improving Access to Psychological Therapies (IAPT) services-the largest platform for treating depression and anxiety in England, UK. Secondary aims were to investigate i) whether individual personality difficulties are associated with treatment outcome and ii) whether findings are moderated by treatment type.

The sample included 3,689 adults who accessed community-based psychological treatment (cognitive behavioural therapy, emotional skills training, or other psychological therapy) for depression and/or anxiety disorder. Associations between personality difficulties (assessed with the Standardised Assessment of Personality-Abbreviated Scale (SAPAS)) and treatment outcomes (recovery and reliable improvement in depression/anxical treatment for depression/anxiety disorder. If replicated, the findings highlight a major challenge to the way community-based psychological therapy services in England (IAPT services) are presently constituted.
Depression and post-traumatic stress disorder (PTSD) are among the most common psychiatric disorders observed in children and adolescents exposed to sexual abuse.

selleck chemical aimed to investigate the effects of many factors such as the characteristics of a child, abuse, and the abuser, family type of the child, and the role of social support in the development of psychiatric disorders using machine learning techniques.

The records of 482 children and adolescents who were determined to have been sexually abused were examined to predict the development of depression and PTSD.

Each child was evaluated by a child and adolescent psychiatrist in the psychiatric aspect according to the DSM-V. Through the data of both groups, a predictive model was established based on a random forest classifier.

The mean values and standard deviation of the 10-k cross-validated results were obtained as accuracy 0.82% (+/- 0.19%), F1 0.81% (+/- 0.19%), precision 0.81% (+/- 0.19%), recall 0.80% (+/- 0.19%) for children with depression; and accuracy 0.72% (+/- 0.12%), F1 0.71% (+/- 0.12%), precision 0.72% (+/- 0.12%), recall 0.71% (+/- 0.12%) for children with PTSD, respectively. ROC curves were drawn for both, and the AUC results were obtained as 0.88 for major depressive disorder and 0.76 for PTSD.

Machine learning techniques are powerful methods that can be used to predict disorders that may develop after sexual abuse. The results should be supported by studies with larger samples, which are repeated and applied to other risk groups.

Repetitive transcranial magnetic stimulation (rTMS) has established efficacy in the treatment of unipolar depression and a growing evidence base in the treatment of bipolar depression. The objective of this study was to provide an estimate of the efficacy of rTMS in bipolar depression as an up to date synthesis of this literature is lacking.

We conducted a systematic review of the sham-controlled randomized controlled trial (RCT) literature examining rTMS in bipolar depression. Studies were included if they included participants with bipolar depression in both sham- and active arms. The primary outcome parameter was rate of clinical response, defined as a 50% reduction as compared to baseline, on an established depression rating scale. Quantitative synthesis was performed using the Maentel-Haenszel random-effects model.

Data from a total of 274 patients from 14 studies were retained in the quantitative synthesis. The response rates were higher in rTMS compared to sham treatment (odds ratio (OR) = 2.72. 95%CI 1.44-5.14). When stimulation protocols were analysed separately, statistically significant clinical response was only observed for high-frequency rTMS over the left dorsolateral prefrontal cortex (OR = 2.57, 95%CI 1.17-5.66).

Most data was extracted from trials including very few participants with bipolar depression (predominantly unipolar depression samples). link2 Large confirmatory RCTs of rTMS specifically for bipolar depression are lacking.

rTMS seems effective in the treatment of bipolar depression, but dedicated and adequately powered RCTs are needed in order to firmly conclude that rTMS should be offered routinely for the treatment of bipolar depression.

The glutamatergic modulator ketamine rapidly reduces depressive symptoms in individuals with treatment-resistant major depressive disorder (MDD). link3 However, ketamine's effects on emotional processing biases remain largely unknown, and understanding these processes may help elucidate ketamine's mechanism of action.

Magnetoencephalography (MEG) was used to investigate ketamine's effects on early visual responses to affective stimuli in individuals with MDD (n=31) and healthy volunteers (HVs; n=24). Participants were enrolled in a double-blind, placebo-controlled, crossover clinical trial and were assessed at baseline and after subanesthetic-dose ketamine and placebo-saline infusions. During MEG recording, participants completed an emotional evaluation task in which they indicated the sex or emotional valence (happy-neutral or sad-angry) of facial stimuli. Source-localized event-related field (ERF) M100 and M170 amplitudes and latencies were extracted from regions of interest. Linear fixed effects models examined interactions between diagnosis, stimulus valence, and drug session for behavioral and MEG data.

In baseline behavioral analyses, MDD participants exhibited higher accuracy for sad-angry than happy-neutral faces, and HVs responded faster to happy-neutral than sad-angry faces. In the MEG post-infusion analyses, calcarine M100 amplitudes were larger in MDD than HV participants post-placebo but became more similar post-ketamine. Finally, fusiform M170 amplitudes were associated with antidepressant response in MDD participants.

The modest sample size and the need to collapse across responses to happy and neutral faces to increase statistical power limit the generalizability of the findings.

Ketamine rapidly altered emotional stimulus processing in MDD, laying the groundwork for future investigations of biomarkers of antidepressant treatment response.

Clinicaltrials.gov, NCT#00088699.Following peripheral nerve injury, macrophages are recruited to the injury site from circulation to clear cellular debris. Injured β-secretase 1 (BACE1) knockout mice have enhanced macrophage recruitment and debris clearance, which may be due to BACE1 activity in macrophages or the hypomyelination observed in BACE1 knockout mice. To assess if BACE1 expression by macrophages mediates enhanced macrophage recruitment we utilized mice with macrophage specific deletion of BACE1 and saw no increase in macrophage recruitment following injury. This study suggests that expression of BACE1 by macrophages may not be essential for increased recruitment observed previously in global BACE1 KO mice.
