Mental disorders and nicotine dependence among pregnant women in the United States

OBJECTIVE: To investigate the association between mental disorders and cigarette use and nicotine dependence among pregnant women in the United States. METHODS: A face-to-face general population survey was conducted on participants in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions. One thousand five hundred sixteen women reporting a pregnancy in the past year were captured. Primary outcomes were seven Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-defined mood and anxiety disorders and eight personality disorders, which were measured with the Alcohol Use Disorder and Associated Disabilities Interview Schedule. RESULTS: Among pregnant women, 21.7% reported cigarette use and 12.4% met the criteria for nicotine dependence. Among pregnant women with cigarette use, 45.1% met criteria for at least one mental disorder, and among those with nicotine dependence, 57.5% met criteria for at least one other mental disorder. After adjusting for demographics and comorbidity, nicotine dependence during pregnancy significantly predicted any mental disorder (odds ratio [OR] 3.3, 95% confidence interval [CI] 2.1-5.1), any mood disorder (OR 2.5, 95% CI 1.5-4.0), major depression (OR 2.07, 95% CI 1.3-3.4), dysthymia (OR 6.2, 95% CI 2.9-13.1), and panic disorder (OR 3.1, 95% CI 1.6-6.1) in the past year. No significant associations were found between nondependent cigarette use and mental disorders. CONCLUSION: Our results suggest an association between mental disorders and nicotine dependence among pregnant women in the United States. This association has far-reaching implications for both the mental and physical health of women and potentially for their children. LEVEL OF EVIDENCE: III.     

Progesterone for the prevention of preterm birth in women with multiple pregnancies: the AMPHIA trial

Background

Adequate vitamin D concentrations during pregnancy are necessary to neonatal calcium homeostasis, bone maturation and mineralization. The aim of study is to evaluate serum vitamin D concentrations in mothers and their newborns and effect of vitamin D deficiency on pregnancy outcomes.

Methods

552 pregnant women were recruited from Tehran University educating hospitals in the winter of 2002. Maternal and cord blood samples were taken at delivery. The serum was assayed for 25-hydroxyvitamin D3, calcium, phosphorus and parathyroid hormone.

Results

The prevalence of vitamin D deficiency in maternal and cord blood samples were 66.8% and 93.3%, respectively (<35 nmol/l). There was significant correlation between maternal and cord blood serum concentrations of vitamin D. In mothers with vitamin D deficiency, cord blood vitamin D concentrations was lower than those from normal mothers (P = .001). Also, a significant direct correlation was seen between maternal vitamin D intake and weight gain during pregnancy.

Conclusion

Consideration to adequate calcium and vitamin D intake during pregnancy is essential. Furthermore, we think it is necessary to reconsider the recommendation for vitamin D supplementation for women during pregnancy.     

Shoulder magnetic resonance imaging findings in manual wheelchair users with spinal cord injury

Objective: To investigate the prevalence of rotator cuff and long head of the biceps pathologies in manual wheelchair (MWC) users with spinal cord injury (SCI).Design: Cross-sectional study.Setting: Outpatient clinic at a tertiary medical center.Participants: Forty-four adult MWC users with SCI (36 men and 8 women) with an average age (SD) of 42 (13) years. SCI levels ranged from C6 to L1; complete and incomplete SCI.Outcome Measures: Participants’ demographic and anthropometric information, presence of shoulder pain, Wheelchair User’s Pain Index (WUSPI) scores, and magnetic resonance imaging findings of shoulder pathologies including tendinopathy, tendon tears, and muscle atrophy.Results: Fifty-nine percent of the participants reported some shoulder pain. The prevalence of any tendinopathy across the rotator cuff and the long head of biceps tendon was 98%. The prevalence of tendinopathy in the supraspinatus was 86%, infraspinatus was 91%, subscapularis was 75%, and biceps was 57%. The majority of tendinopathies had mild or moderate severity. The prevalence of any tears was 68%. The prevalence of tendon tears in the supraspinatus was 48%, infraspinatus was 36%, subscapularis was 43%, and biceps was 12%. The majority of the tears were partial-thickness tears. Participants without tendon tears were significantly younger (P < 0.001) and had been wheelchair user for a significantly shorter time (P = 0.005) than those with tendon tears.Conclusion: Mild and moderate shoulder tendinopathy and partial-thickness tendon tears were highly prevalent in MWC users with SCI. Additionally, the findings of this study suggest that strategies for monitoring shoulder pathologies in this population should not be overly reliant on patient-reported pain, but perhaps more concerned with years of wheelchair use and age.     

Clinical features and serum antinuclear antibodies in 230 Danish patients with systemic sclerosis

The objective was to investigate the relationship between the presence of different types of antinuclear antibodies (ANA) in patients with systemic sclerosis (SSc) and the presence of clinical features. Sera from 230 patients with SSc were tested for the presence of ANA, including anticentromere antibodies (ab), antitopoisomerase I ab, anti- U1 RNP ab and antinucleolar ab, including anti-Th RNP, anti-U3 RNP and anti-U17 RNP. Clinical features were registered prospectively in a clinical database. Eighty-two per cent of the patients were women. The median age was 58 yr (45-67, quartiles) and median age at disease onset was 44 (30-55) yr. ANA were found in 86% of the patients (anticentromere: 34%; antitopoisomerase I: 14%; anti-U1 RNP: 6.5%; antinucleolar total: 16%; anti-Th RNP: 2.2%; anti-U3 RNP: 3.5%; anti- U17 RNP: 0%). Anticentromere ab were found to be related to a high prevalence of calcinosis, telangiectasia, digital ulcers, acrosclerosis, primary biliary cirrhosis, isolated reduction of pulmonary diffusing capacity, and a low prevalence of radiological evidence of pulmonary fibrosis. Antitopoisomerase I ab were associated with a high prevalence of digital joint deformity, distal osteolysis, radiological signs of pulmonary fibrosis, a low prevalence of calcinosis and late onset of disease. Anti-U1 RNP ab were related to a high prevalence of arthritis and myositis, a low prevalence of calcinosis, and early disease onset. The presence of antinucleolar ab, including anti-U3 RNP and anti-Th RNP, was not significantly related to any particular clinical features in this study; possibly due to the small number of patients with these ab. The presence of anticentromere, antitopoisomerase I and anti-U1 RNP ab in the serum was also found to have previously described clinical correlations in a group of Danish SSc patients.      

Proton Pump Inhibitors Versus Histamine-2 Receptor Antagonists Likely Increase Mortality in Critical Care: An Updated Meta-Analysis

BackgroundUpper gastrointestinal bleeding is common among the critically ill. Recently, the Proton Pump Inhibitors (PPIs) vs. Histamine-2 Receptor Blockers for Ulcer Prophylaxis Therapy in the Intensive Care Unit (PEPTIC) trial suggested PPIs might increase mortality. We performed an updated meta-analysis to further inform discussion.MethodsWe leveraged 2 recent systematic reviews to identify randomized controlled trials directly comparing PPIs and H-2 Receptor Antagonists (H2RAs) for stress ulcer prophylaxis in critically ill patients and reporting mortality. We extracted mortality data from each study and meta-analyzed them with the PEPTIC trial using a random effects model.ResultsOf 28,559 total patients, 14,436 (50.5%) were allocated to PPI and 14,123 to H2RAs (49.5%). Compared to H2RAs, the pooled relative risk for mortality was 1.05 (95% confidence interval 1.00-1.10) with an estimated risk difference for mortality of 9 additional deaths per 1000 patients exposed to PPI (95% confidence interval 0-18); heterogeneity was low (I² = 0%; P = 0.826).ConclusionsStress ulcer prophylaxis with PPIs likely increases mortality compared to H2RAs. Whether stress ulcer prophylaxis is beneficial in critical care remains open to further study.     

Preclinical to Clinical Translation of CNS Transporter Occupancy of TD-9855, a Novel Norepinephrine and Serotonin Reuptake Inhibitor

Background:

Monoamine reuptake inhibitors exhibit unique clinical profiles that reflect distinct engagement of the central nervous system (CNS) transporters.

Methods:

We used a translational strategy, including rodent pharmacokinetic/pharmacodynamic modeling and positron emission tomography (PET) imaging in humans, to establish the transporter profile of TD-9855, a novel norepinephrine and serotonin reuptake inhibitor.

Results:

TD-9855 was a potent inhibitor of norepinephrine (NE) and serotonin 5-HT uptake in vitro with an inhibitory selectivity of 4- to 10-fold for NE at human and rat transporters. TD-9855 engaged norepinephrine transporters (NET) and serotonin transporters (SERT) in rat spinal cord, with a plasma EC₅₀ of 11.7ng/mL and 50.8ng/mL, respectively, consistent with modest selectivity for NET in vivo.Accounting for species differences in protein binding, the projected human NET and SERT plasma EC₅₀ values were 5.5ng/mL and 23.9ng/mL, respectively. A single-dose, open-label PET study (4–20mg TD-9855, oral) was conducted in eight healthy males using the radiotracers [¹¹C]-3-amino-4- [2-[(di(methyl)amino)methyl]phenyl]sulfanylbenzonitrile for SERT and [¹¹C]-(S,S)-methylreboxetine for NET. The long pharmacokinetic half-life (30–40h) of TD-9855 allowed for sequential assessment of SERT and NET occupancy in the same subject. The plasma EC₅₀ for NET was estimated to be 1.21ng/mL, and at doses of greater than 4mg the projected steady-state NET occupancy is high (>75%). After a single oral dose of 20mg, SERT occupancy was 25 (±8)% at a plasma level of 6.35ng/mL.

Conclusions:

These data establish the CNS penetration and transporter profile of TD-9855 and inform the selection of potential doses for future clinical evaluation.

Iron status and anemia in the elderly: new findings and a review of previous studies

Iron status was determined in 280 free-living and healthy elderly men (n = 131) and women (n = 149) by assessing dietary and supplemental iron intake as well as ten biochemical measures of iron nutriture (erythrocyte count, hemoglobin level, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, plasma iron level, total iron-binding capacity, per cent transferrin saturation, and ferritin level). Subject ages ranged from 60 to 93 years with a median age of 72 years for both women and men. For comparison purposes, iron status measures in an unselected group of younger men (n = 107) and women (n = 164) between the ages of 20 and 39 years were also obtained. None of the elderly women and only two (1.2 per cent) of the younger women had low hemoglobin levels (less than 12.0 g/dl). Three (2.3 per cent) of the elderly men and none of the younger men had low hemoglobin levels (less than 14 g/dl). Other iron status measures revealed that anemia or iron deficiency was no more prevalent in the healthy elderly population than in the younger adult population when identical criteria were used to assess iron nutriture. The genesis of anemia often seen in the elderly is not completely understood. Reported evidence suggests the presence of anemia in the elderly is a result of overall reduction of hematopoietic reserves. Because of the potentially serious consequences of this assumption about anemia to the treatment of the elderly, the authors critically review some of the studies that have been designed in the past to determine the prevalence and etiology of anemia in the aged. They suggest that health status, race, socioeconomic status, diet, and region are more important than age as explanations for the high prevalence of anemia seen in many previous studies.
