Axis I and II disorders as long-term predictors of mental distress: a six-year prospective follow-up of substance-dependent patients

<p>Abstract</p> <p>Background</p> <p>A high prevalence of lifetime psychiatric disorders among help-seeking substance abusers has been clearly established. However, the long-term course of psychiatric disorders and mental distress among help-seeking substance abusers is still unclear. The aim of this research was to examine the course of mental distress using a six-year follow-up study of treatment-seeking substance-dependent patients, and to explore whether lifetime Axis I and II disorders measured at admission predict the level of mental distress at follow-up, when age, sex, and substance-use variables measured both at baseline and at follow-up are controlled for. </p> <p>Methods</p> <p>A consecutive sample of substance dependent in- and outpatients (n = 287) from two counties of Norway were assessed at baseline (T1) with the Composite International Diagnostic Interview (Axis I), Millon's Clinical Multiaxial Inventory (Axis II), and the Hopkins Symptom Checklist (HSCL-25 (mental distress)). At follow-up (T2), 48% (137/287 subjects, 29% women) were assessed with the HSCL-25, the Alcohol Use Disorders Identification Test, and the Drug Use Disorders Identification Test. </p> <p>Results</p> <p>The stability of mental distress is a main finding and the level of mental distress remained high after six years, but was significantly lower among abstainers at T2, especially among female abstainers. Both the number of and specific lifetime Axis I disorders (social anxiety disorder, generalized anxiety disorder, and somatization disorder), the number of and specific Axis II disorders (anxious and impulsive personality disorders), and the severity of substance-use disorder at the index admission were all independent predictors of a high level of mental distress at follow-up, even when we controlled for age, sex, and substance use at follow-up.</p> <p>Conclusion</p> <p>These results underscore the importance of diagnosing and treating both substance-use disorder and non-substance-use disorder Axis I and Axis II disorders in the same programme.</p

Estudo comparativo dos meios de contraste baritado e iodado-iônico e não-iônico no trato respiratório de ratos Comparative study of barium and iodine agents - ionic and nonionic on the respiratory tract of the rats

OBJETIVO: Durante estudos radiológicos pode ocorrer a passagem do meio de contraste para a árvore traqueo-brônquica, determinando reações adversas e até fatais. O objetivo deste estudo é conhecer as alterações desencadeadas no trato respiratório pela presença do meio de contraste. MÉTODOS: Utilizaram-se 91 ratos divididos, aleatoriamente, em 4 grupos. Um grupo de controle não manipulado com 7 animais e os demais grupos com 21 ratos. O grupo controle manipulado recebeu solução fisiológica e os grupos de experimento: bário, iodo ônico e iodo não iônico conforme o grupo a que pertenciam. Sob anestesia e visibilização direta da traquéia, injetou-se 0,75 ml/kg (0,25 ml) do meio de contraste de acordo com o grupo ao qual pertencesse o animal. Realizaram-se as aferições com 1 hora, 1 dia e 1 semana. Os ratos foram sorteados para a autanásia nos três tempos estudados. Fez-se documentação radiográfica seguida da ressecção dos pulmões e exame histo-patológico. RESULTADOS: Na primeira hora, no grupo que recebeu bário, os campos médios e o superior direito ficaram acometidos. Nos grupos que receberam iodo iônico e iodo não iônico, todo o pulmão direito mostrava-se opacificado. Nas avaliações de uma dia e 1 semana os grupos que receberam iodo estavam normais enquanto que o grupo que recebeu bário mostrava comprometimento dos campos médios. No estudo histo-patológico observou-se, no grupo que recebeu bário, na avaliação de uma semana, grande quantidade de macrófagos intra-alveolares, perivasculares e peribrônquicos. CONCLUSÃO: Os contrastes iodados iônico e não iônico levam a alterações passageiras enquanto que o bário promove reação inflamatória crônica com manutenção da tradução radiográfica, no rato.<br>PURPOSE: During roadiologic studies, passage of the contrast medium to the tracheobronchial tree may occur, causibng adverse or even fatal reactions. The objective of the present study was to determine the changes in the respiratory tract triggered by the presence of contrast medium. METHODS: Ninety-one rats were divided at random into 5 groups, i.e., an intact control group of 7 animals and 4 groups of 21 rats each. The manipulated control group received physiological saline and the experimental groups respectively received barium, ionic iodine and non-ionic iodine. Under anesthesia and direct visualization of the trachea, 0.75 ml/kg (0.25 ml) of the contrast medium was injected into the animals of each group. The effects of the procedure were determined after 1 hour, 1 day and 1 week, with the animals being sacrificed at each time point by drawing lots. Radiographic documentation was obtained, followed by resection and histopathologic examination of the lungs. RESULTS: After 1 hour, the middle fields and the right upper field were involved in the group injected with barium. In the groups injected with ionic iodine and non-ionic iodine, the entire right lung was found to be opacified. After 1 day and 1 week, the groups injected with iodine were normal, whereas the group injected with barium showed involvement of the middle fields. After 1 week, histopathologic examination revealed that the group injected with barium exhibited large amounts of intra-alveolar, perivascular and peribronchial macrophages CONCLUSION: The ionic and non-ionic iodine contrast media led to temporary changes, whereas barium promoted a chronic inflammatory reaction with maintenance of radiographic translation

Adrenal function links to early postnatal growth and blood pressure at age 6 in children born extremely preterm.

BACKGROUND: Low birth weight in term-born individuals correlates with adverse cardiometabolic outcomes; excess glucocorticoid exposure has been linked to these relationships. We hypothesized that cortisol and adrenal androgens would correlate inversely with birthweight and directly with markers of cardiometabolic risk in school-aged children born extremely preterm; further, preterm-born would have increased cortisol and adrenal androgens compared to term-born children. METHODS: Saliva samples were obtained at age 6 from 219 preterm-born children followed since birth and 40 term-born children and analyzed for dehydroepiandrosterone (DHEA) and cortisol. Cortisol was also measured at home (awakening, 30\u27 later, evening). RESULTS: For preterm-born children, cortisol and DHEA correlated inversely with weight and length Z-scores at 36 weeks PMA and positively with systolic BP. DHEA was higher in preterm-born than term-born children (boys p \u3c 0.01; girls p = 0.04). Cortisol was similar between preterm-born and term-born at study visit; however, preterm-born children showed a blunted morning cortisol. In term-born children, DHEA correlated with BMI (p = 0.04), subscapular, and abdominal skinfold thicknesses (both p \u3c 0.01). CONCLUSION: Cortisol and DHEA correlated inversely with early postnatal growth and directly with systolic BP in extremely preterm-born children, suggesting perinatal programming. Blunted morning cortisol may reflect NICU stress, as seen after other adverse childhood experiences (ACEs)

T cell and monocyte/macrophage activation markers associate with adverse outcome, but give limited prognostic value in anemic patients with heart failure: results from RED-HF

BackgroundActivated leukocytes may contribute to the development and progression of heart failure (HF). We investigated the predictive value of circulating levels of stable and readily detectable markers reflecting both monocyte/macrophage and T-cell activity, on clinical outcomes in HF patients with reduced ejection fraction (HFrEF).MethodsThe association between baseline plasma levels of soluble CD163 (sCD163), macrophage migration inhibitory factor (MIF), granulysin, soluble interleukin-2 receptor (sIL-2R), and activated leukocyte cell adhesion molecule (ALCAM) and the primary endpoint of death from any cause or first hospitalization for worsening of HF was evaluated using multivariable Cox proportional hazard models in 1541 patients with systolic HF and mild to moderate anemia, enrolled in the Reduction of Events by darbepoetin alfa in Heart Failure (RED-HF) trial. Modifying effects and interaction with darbepoetin alfa treatment were also assessed.ResultsAll leukocyte markers, except granulysin, were associated with the primary outcome and all-cause death in univariate analysis (all
