An exploratory study of adolescent response to fluoxetine using psychological and biological predictors

Impact of antidepressant treatment on complete blood count parameters and inflammatory ratios in adolescents with major depressive disorder

Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) are novel biomarkers of systemic inflammation in depression. This study aims to examines the impact of selective serotonin reuptake inhibitor (SSRI) treatment on complete blood count (CBC) parameters and inflammatory ratios in major depressive disorder (MDD). CBC parameters and inflammatory ratios were examined in a total of 45 drug-naive adolescents with MDD and were compared before and after SSRI treatment for 12 weeks and between responders and nonresponders. Following SSRI treatment in MDD, the red blood cell (RBC) count, hematocrit, and red cell distribution width (RDW) significantly increased. Hemoglobin tended to increase. The MCV, MCH, and MCHC values decreased significantly. White blood cell count, neutrophil percentage, monocyte count, and monocyte and basophil percentages decreased significantly. The percentage of lymphocytes significantly increased. The MLR decreased, whereas the NLR tended to decrease. Platelet count and PLR did not change significantly. A higher platelet count at baseline has been associated with non-response to SSRI treatment in patients with MDD. SSRI treatment increased RBC count, hematocrit, RDW, and lymphocyte percentage, and reduced MLR, and neutrophil and monocyte percentages in responders MDD. We suggest higher platelet counts at baseline as a potential predictor of nonresponders.

The association of Type D personality with functional outcomes, quality of life and neuropathic pain in persons with spinal cord injury

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

This study aimed to investigate the association of Type D personality (TDP) with functional outcomes, health-related quality of life (HRQoL) and neuropathic pain in persons with spinal cord injury (SCI), using dichotomous and continuous analysis methods.

SETTING

Tertiary rehabilitation center.

METHODS

This study included 105 persons with SCI. Independence level was determined using the Functional Independence Measure (FIM)-motor subscale. The Short Form-36 questionnaire (SF-36) was used to assess HRQoL. TDP (combined existence of negative affectivity and social inhibition) was assessed using Type D Scale-14 (DS-14). Presence of chronic pain was questioned and the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Scale was used to distinguish neuropathic pain from others.

RESULTS

In dichotomous method, the FIM-motor score was significantly lower in persons with TDP (41 persons, 39%) (p = 0.025). Persons with TDP had significantly lower scores in vitality, emotional role and mental health. There was no significant difference between the groups, regarding neuropathic pain and LANSS scores (p > 0.05 for all). Negative affectivity and total DS-14 scores had negative correlation with mental health and vitality. In continuous interaction method, TDP predicted mainly the mental health components of SF-36 (particularly, vitality and mental health). Negative affectivity was the driving factor. TDP was not associated with FIM-motor, VAS pain or LANSS scores.

CONCLUSIONS

Mental component of HRQoL is associated with Type D in persons with SCI in both analyses. Assessment of potential differences related with TDP may be beneficial to develop and apply person-specific goals in SCI rehabilitation.

"Silence! The body is speaking" - a correlational study of personality, perfectionism, and self-compassion as risk and protective factors for psychosomatic symptoms distress

The current study examined the role of personality traits on psychosomatic distress (PD) and tested the hypothesis that the association between perfectionism and PD would be moderated by self-compassion. One hundred and seventy-three community volunteers, of whom 24.9% were men, mean age 31.52 ± 13.29, reported online on the DS14, a measure of Type D personality, on the TCI-140, a measure of temperament and character, on the Frost multidimensional perfectionism scale, on the short form of the self-compassion scale and on the SOMS-7 for psychosomatic symptoms. We defined psychosomatic distress as the product of the symptom count and severity rating score of the SOMS-7. The hierarchical linear regression model that included all the personality variables as well as the interaction term between self-compassion and perfectionism accounted for 25% of the variance in PD. The interaction between perfectionism and self-compassion entered into the model in the last block was highly protective. High self-compassion moderated the effect of perfectionism on PD. Our finding correspond with the notion that personality can enhance PD but can also mitigate it. Protective personality traits, such as self-compassion, might be good targets for psychological intervention.
