CONTEXT One or both commercial tuberculin skin test reagents (Aplisol and Tubersol) may have a high rate of false-positive reactions. OBJECTIVE To compare the reaction size and specificity of skin testing with Aplisol, Tubersol, and the standard purified protein derivative (PPD-S1). DESIGN Double-blind trial, conducted between May 14, 1997, and October28, 1997, in which each individual rece...

OBJECTIVE To identify the frequency, risk factors, and clinical forms of postpartum depression (PPD) in Kinshasa. METHODS In a cross-sectional study in well-baby clinics in Kinshasa in 2009, 120 mothers of 61 boys and 59 girls aged 1-10 months agreed to participate in the study. Their mean age was 28.4 ± 12.2 years. The Edinburgh Postnatal Depression Scale, the Goldberg Scales of Anxiety and ...

Objective: To study the prevalence of Post Partum Depression (PPD)in Indian women and to evaluate the risk factors for the development of PPD. Materials And Methods: This cross-sectional study was done among 278 novel mothers (post delivery 10 days to 3 months) attending post partum clinics of K.P.C.Medical College & Hospital. Socio-economic factors and detailed obstetric variables were assesse...

The current study examines mechanisms of racial differences in symptoms of paranoid personality disorder (PPD) in a sample of adults ages 55-64 from the St. Louis, MO area. Socioeconomic status (SES) and childhood trauma were tested as intervening variables in the association between race and PPD symptoms using structural equation modeling. PPD symptoms were modeled as a latent variable compose...

Postpartum depression (PPD) affects up to 1 in 8 women. The early postpartum period is characterized by a downward physiological shift from relatively elevated levels of sex steroids during pregnancy to diminished levels after parturition. Sex steroids influence functional brain connectivity in healthy non-puerperal subjects. This study tests the hypothesis that PPD is associated with attenuati...

AIM The aim of this study is to interpret purified protein derivative (PPD) induration sizes with respect to the number of Bacillus Calmette-Guérin (BCG) scars. METHODS We have considered 1879 school children between the ages of 7 and 14 years from seven primary schools in Kocaeli, Turkey. Children were injected with 5TU 0.1 mL PPD and induration sizes were measured at 72 h. Number of BCG sca...

Ambient temperature has a large impact on reproductive development and grain yield in temperate cereals. However, little is known about the genetic control of development under different ambient temperatures. Here, we demonstrate that in barley (Hordeum vulgare), high ambient temperatures accelerate or delay reproductive development depending on the photoperiod response gene PHOTOPERIOD1 (Ppd-H...

We have previously shown, in renal transplant recipients on maintenance immunosuppression, that a whole-blood assay was superior in detecting immunity towards purified protein derivative (PPD) compared with skin testing. As blood tests may have limitations during high-dose immunosuppression therapy, the present study was aimed at characterising the effect of high immunosuppressive drug levels o...

In barley (Hordeum vulgare), PHOTOPERIOD1 (Ppd-H1) acts as a major positive regulator of flowering under long-day conditions, while VERNALIZATION2 (VRN-H2) is a strong repressor of flowering under long days before vernalization. By contrast, CONSTANS (CO) plays a key role in the photoperiodic regulation of flowering in Arabidopsis (Arabidopsis thaliana). Here, we study the role of the closest b...

Background Postpartum depression (PPD) is a common complication of pregnancy, affecting approximately 13% of mothers internationally. Previous research has examined whether epidural analgesia used for pain control during labor and birth is associated with a lower risk of PPD, but reports conflicting results and may have suffered from methodological shortcomings. Our study aimed to prospectively...
