Does antipsychotic drug use increase the risk of long term mortality? A systematic review and meta-analysis of observational studies

Antipsychotics (AP) are widely used to treat schizophrenia and other psychiatric disorders. However, the association between the AP use and mortality risk is controversial. We searched PubMed, EMBASE, MEDLINE, PsycINFO, CINAHL, the Cochrane Library and four Chinese databases from inception to June 2016. All observational cohort or case–control studies reporting data on mortality outcomes in individuals exposed to AP drugs were included. This systematic review included 68 studies involving 4,812,370 participants. Sixty-seven studies reported confounding factors, the most common being age, sex, race, concomitant medications, and comorbidities. For all-cause mortality, current users of AP and conventional antipsychotics (CAP) had higher mortality risk than did non-AP users [AP users: RR, 1.50; 95% CI, 1.12 to 1.99; CAP users: RR, 1.53; 95% CI, 1.16 to 2.04]. However, the association between the current use of atypical antipsychotics (AAP) and the mortality was of borderline significance, and there was no significant difference for past users of AP. Mortality was higher in current CAP users than in current AAP users. For cardiac death and sudden death, current AP and CAP users also had higher mortality risk than non-AP users. A subgroup analysis showed a possible increased risk in patients with Parkinson’s, but not in those with dementia, Alzheimer’s disease, schizophrenia, delirium or stroke. An increased risk of all-cause mortality for patients ≧65 years may also exist. AP exposure is associated with an approximately 1.5-fold increased mortality risk. This increased risk may be particularly prominent in patients with Parkinson’s and those over 65 years old. Further studies are required to evaluate the mortality risk for individual AP drugs and diseases.
Effect of beta-carotene supplementation and lactation on carotenoid metabolism and mitogenic T lymphocyte proliferation.

BACKGROUND Information is lacking regarding the effects of beta-carotene supplementation, early lactation, or both on circulating carotenoid concentrations and T lymphocyte proliferation. OBJECTIVES This study investigated the effects of short-term beta-carotene supplementation (30 mg/d for 28 d) during early lactation (days 4-32 postpartum) on circulating carotenoid concentrations and on the T lymphocyte proliferative response to phytohemagglutinin. DESIGN Subjects aged 19-39 y were paired [lactating (4 d postpartum) and nonlactating (never pregnant, healthy women)] and randomly assigned to receive either beta-carotene or a placebo. During the study, subjects provided eight 24-h food records for analysis with the NUTRITIONIST IV and US Department of Agriculture carotenoid databases. Nonfasting blood samples were collected at baseline and at 28 d. Plasma analysis included quantification of alpha-carotene, beta-carotene, lutein, lycopene, retinol, and alpha-tocopherol, complete differential blood cell counts, and lymphocyte proliferative activity. RESULTS beta-Carotene supplementation increased beta-carotene (P < 0.001) and alpha-carotene (P < 0.05) concentrations but did not affect lycopene concentrations significantly. Supplemented women showed significant decreases in plasma lutein (P < 0.03), as did lactating subjects (P < 0.02). Neither lactation nor beta-carotene supplementation affected the T lymphocyte proliferative response to phytohemagglutinin. CONCLUSIONS Our results suggest that beta-carotene supplementation as well as some events related to parturition, initiation of lactation, or both alter circulating concentrations of lutein. beta-Carotene supplementation does not enhance T lymphocyte immune competence in healthy women.
The Movement Disorder Society Evidence‐Based Medicine Review Update: Treatments for the motor symptoms of Parkinson's disease

The objective was to update previous evidence‐based medicine reviews of treatments for motor symptoms of Parkinson's disease published between 2002 and 2005. Level I (randomized, controlled trial) reports of pharmacological, surgical, and nonpharmacological interventions for the motor symptoms of Parkinson's disease between January 2004 (2001 for nonpharmacological) and December 2010 were reviewed. Criteria for inclusion, clinical indications, ranking, efficacy conclusions, safety, and implications for clinical practice followed the original program outline and adhered to evidence‐based medicine methodology. Sixty‐eight new studies qualified for review. Piribedil, pramipexole, pramipexole extended release, ropinirole, rotigotine, cabergoline, and pergolide were all efficacious as symptomatic monotherapy; ropinirole prolonged release was likely efficacious. All were efficacious as a symptomatic adjunct except pramipexole extended release, for which there is insufficient evidence. For prevention/delay of motor fluctuations, pramipexole and cabergoline were efficacious, and for prevention/delay of dyskinesia, pramipexole, ropinirole, ropinirole prolonged release, and cabergoline were all efficacious, whereas pergolide was likely efficacious. Duodenal infusion of levodopa was likely efficacious in the treatment of motor complications, but the practice implication is investigational. Entacapone was nonefficacious as a symptomatic adjunct to levodopa in nonfluctuating patients and nonefficacious in the prevention/delay of motor complications. Rasagiline conclusions were revised to efficacious as a symptomatic adjunct, and as treatment for motor fluctuations. Clozapine was efficacious in dyskinesia, but because of safety issues, the practice implication is possibly useful. Bilateral subthalamic nucleus deep brain stimulation, bilateral globus pallidus stimulation, and unilateral pallidotomy were updated to efficacious for motor complications. Physical therapy was revised to likely efficacious as symptomatic adjunct therapy. This evidence‐based medicine review updates the field and highlights gaps for research. © 2011 Movement Disorder Society
Skeletal muscle function in malnutrition.

Skeletal muscle function was studied in 10 malnourished patients with various gastrointestinal disorders and in 22 normal subjects. The function of the adductor pollicis muscle was assessed by electrical stimulation of the ulnar nerve. The objective parameters of muscle function measured were: 1) Force of contraction expressed as a percentage of the maximal force obtained with electrical stimulation at 10, 20, 30, 50 and 100 Hz. 2) Maximal relaxation rate expressed as percentage force loss/! 10 ms. 3) Endurance expressed as percentage force loss/30 s. The force of contraction at 10 Hz was higher in malnourished patients compared with normal subjects, with a mean +/- SEM (n) of 43.0 +/- 4.2% (n = 10) and 28.8 +/- 1.2% (n = 22), respectively, (p less than 0.001). The maximal relaxation rate was slower in patients compared with normals with a mean +/- SEM (n) of 7.2 +/- 0.4% (n = 9) ad 9.6 +/- 0.2% (n = 22), respectively, (p less than 0.001). Muscle endurance testing showed an increased force loss with prolonged tetanic stimulation in patients compared with normals, with a mean +/- SEM (n) of 29.1 +/- 4.0% (n = 7) and 3.5 +/- 0.8% (n = 22), respectively, (p less than 0.001). Four patients were restudied after a 4-wk period of total parenteral nutrition, with a significant improvement in muscle function parameters. Malnutrition results in both increased muscle fatiguability and an altered pattern of muscle contraction and relaxation which are reversible by nutritional supplementation. This technique promises to be valuable in assessing the functional effects of malnutrition and the response to nutritional support.
[13C]linoleic acid oxidation and transfer into milk in stunted lactating women with contrasting body mass indexes.

BACKGROUND The fat concentration of human milk is associated with maternal adiposity, but there is no clear understanding of the mechanisms controlling milk fat concentration. OBJECTIVE We evaluated the effect of postpartum body mass index (BMI; in kg/m(2)) on the metabolic distribution of an oral dose of [13C]linoleic acid in lactating women. DESIGN Ten lactating women stratified by BMI (either <22.5 or >23.5) at 5 mo postpartum received orally 2.5 mg [13C]linoleic acid/kg body wt. Exhaled air, milk, and plasma samples were collected in relation to tracer administration. Linoleic acid was determined by gas chromatography. Dietary intake, serum, milk composition, [13C]linoleic acid enrichment in milk and plasma, and exhaled 13CO2 (by isotope ratio mass spectrometry) were assessed. RESULTS Women with a higher BMI exhaled more 13CO2 than did women with a lower BMI (22.8 +/- 9.4% compared with 8.6 +/- 3.5% of dose, P < 0.03). Cumulated 72-h transfer of [13C]linoleic acid to milk was not significantly different between groups (14.8 +/- 6.5% compared with 17.7 +/- 6.7% of dose). Within the first 9 h after dose administration, 51.6 +/- 4.9% of the total isotope transfer into milk had passed in women with a higher BMI, but only 24.0 +/- 15.3% had passed in those with a lower BMI (P = 0.02). CONCLUSIONS Women with a lower BMI, who were reputed as having less body fat, oxidized and secreted into milk less dietary linoleic acid within 12 h after tracer administration than did women with a higher BMI. In both groups, a large proportion of [13C]linoleic was retained in the maternal compartment, most likely fat tissue, in a slow turnover pool, and released slowly in later hours.
Dietary patterns associated with bone mineral density in premenopausal Japanese farmwomen.

BACKGROUND Because several nutrients are known to affect bone mineral density (BMD), the analysis of dietary patterns or combinations of foods may provide insights into the influence of diet on bone health. OBJECTIVE We evaluated associations between dietary patterns and BMD in Japanese farmwomen. DESIGN The study included 291 premenopausal farmwomen (aged 40-55 y) who participated in the Japanese Multi-centered Environmental Toxicant Study (JMETS; n = 1407). Forearm BMD was measured by using dual-energy X-ray absorptiometry. Diet was assessed by using a validated self-administered diet history questionnaire comprising 147 food items, from which 30 food groups were created and entered into a factor analysis. RESULTS Four dietary patterns were identified. The "Healthy" pattern, characterized by high intakes of green and dark yellow vegetables, mushrooms, fish and shellfish, fruit, and processed fish, was positively correlated with BMD after adjustment for several confounding factors (P = 0.048). In contrast, the "Western" pattern, characterized by high intakes of fats and oils, meat, and processed meat, tended to be inversely associated with BMD; however, the association was not significant (P = 0.08). CONCLUSION A dietary pattern with high intakes of fish, fruit, and vegetables and low intakes of meat and processed meat may have a beneficial effect on BMD in premenopausal women.
Sepsis is associated with increased ubiquitinconjugating enzyme E214k mRNA in skeletal muscle.

Previous studies provided evidence that sepsis is associated with increased ubiquitin-proteasome-dependent protein breakdown in skeletal muscle. The 14-kDa ubiquitin-conjugating enzyme (E214k) has been proposed to be a key regulator of the ubiquitin proteolytic pathway. We tested the hypothesis that E214k message and protein levels are increased in skeletal muscle during sepsis. Sepsis was induced in rats by cecal ligation and puncture (CLP). Control rats were sham operated. E214k mRNA and protein levels were quantitated after Northern and Western blot analysis, respectively, 16 h after CLP or sham operation. Sepsis resulted in a 70% increase in the 1.2-kb E214k transcript in the fast-twitch extensor digitorum longus muscle, whereas no changes were seen in the slow-twitch soleus muscle. E214k protein levels were not influenced by sepsis in any of the muscles studied. Although the changes in the expression of the E214k 1.2-kb transcript paralleled the differential effect of sepsis on protein breakdown in fast- and slow-twitch muscle, the potential role of E214k in the regulation of sepsis-induced muscle proteolysis needs to be interpreted with caution, because the results demonstrated that increased message levels were not associated with increased E214kprotein levels.
Breast-feeding and cognitive development: a meta-analysis.

BACKGROUND Although the results of many clinical studies suggest that breast-fed children score higher on tests of cognitive function than do formula-fed children, some investigators have suggested that these differences are related to confounding covariables such as socioeconomic status or maternal education. OBJECTIVE Our objective was to conduct a meta-analysis of observed differences in cognitive development between breast-fed and formula-fed children. DESIGN In this meta-analysis we defined the effect estimate as the mean difference in cognitive function between breast-fed and formula-fed groups and calculated average effects using fixed-effects and random-effects models. RESULTS Of 20 studies meeting initial inclusion criteria, 11 studies controlled for >/=5 covariates and presented unadjusted and adjusted results. An unadjusted benefit of 5.32 (95% CI: 4.51, 6.14) points in cognitive function was observed for breast-fed compared with formula-fed children. After adjustment for covariates, the increment in cognitive function was 3.16 (95% CI: 2.35, 3.98) points. This adjusted difference was significant and homogeneous. Significantly higher levels of cognitive function were seen in breast-fed than in formula-fed children at 6-23 mo of age and these differences were stable across successive ages. Low-birth-weight infants showed larger differences (5.18 points; 95% CI: 3.59, 6.77) than did normal-birth-weight infants (2.66 points; 95% CI: 2.15, 3.17) suggesting that premature infants derive more benefits in cognitive development from breast milk than do full-term infants. Finally, the cognitive developmental benefits of breast-feeding increased with duration. CONCLUSION This meta-analysis indicated that, after adjustment for appropriate key cofactors, breast-feeding was associated with significantly higher scores for cognitive development than was formula feeding.
Detection of Structural Change in Geographic Regions of Interest by Self Organized Mapping: Las Vegas City and Lake Mead across the Years

Time-series of satellite images may reveal important data about changes in environmental conditions and natural or urban landscape structures that are of potential interest to citizens, historians, or policymakers. We applied a fast method of image analysis using Self Organized Maps (SOM) and, more specifically, the quantization error (QE), for the visualization of critical changes in satellite images of Las Vegas, generated across the years 1984-2008, a period of major restructuration of the urban landscape. As shown in our previous work, the QE from the SOM output is a reliable measure of variability in local image contents. In the present work, we use statistical trend analysis to show how the QE from SOM run on specific geographic regions of interest extracted from satellite images can be exploited to detect both the magnitude and the direction of structural change across time at a glance. Significantly correlated demographic data for the same reference time period are highlighted. The approach is fast and reliable, and can be implemented for the rapid detection of potentially critical changes in time series of large bodies of image data.

Modeling Alzheimer’s and Other Age Related Human Diseases in Embryonic Systems

Modeling human disease in animals is an important strategy to discover potential methods of intervention. We suggest that there is much to be gained by employing a multi-model approach that takes advantage of different animal systems used in the laboratory simultaneously. We use the example of modeling Alzheimer’s disease in Drosophila melanogaster, Caenorhabditis elegans, and Danio rerio to illustrate how such an approach can be employed to investigate the pathophysiology of the disease.
Long-term protein intake and dietary potential renal acid load are associated with bone modeling and remodeling at the proximal radius in healthy children.

BACKGROUND Protein and alkalizing minerals are increasingly described as playing a major role in influencing bone status, not only in the elderly but also in children and adolescents. OBJECTIVE We examined whether the long-term dietary protein intake and diet net acid load are associated with bone status in children. DESIGN In a prospective study design in 229 healthy children and adolescents aged 6-18 y, long-term dietary intakes were calculated from 3-d weighed dietary records that were collected yearly over the 4-y period before a one-time bone analysis. Dietary acid load was characterized as potential renal acid load (PRAL) by using an algorithm including dietary protein, phosphorus, magnesium, and potassium. Proximal forearm bone variables were measured by peripheral quantitative computed tomography. RESULTS After adjustment for age, sex, and energy intake and control for forearm muscularity, BMI, growth velocity, and pubertal development, we observed that long-term dietary protein intake was significantly positively associated with periosteal circumference (P < 0.01), which reflected bone modeling, and with cortical area (P < 0.001), bone mineral content (P < 0.01), and polar strength strain index (P < 0.0001), which reflected a combination of modeling and remodeling. Children with a higher dietary PRAL had significantly less cortical area (P < 0.05) and bone mineral content (P < 0.01). Long-term calcium intake had no significant effect on any bone variable. CONCLUSIONS Long-term dietary protein intake appears to act anabolically on diaphyseal bone strength during growth, and this may be negated, at least partly, if dietary PRAL is high, ie, if the intake of alkalizing minerals is low.
Natural history of brain arteriovenous malformations: systematic review.

INTRODUCTION The appropriate interpretation of natural history of brain arteriovenous malformations (bAVMs) and of factors that negatively affect the risk of future hemorrhage are important when recommending management pathways. With the present systematic review, we aim to provide an overview of the available evidence on natural history of brain arteriovenous malformations (bAVMs), focusing on hemorrhage rates and risk factors for future hemorrhage. EVIDENCE ACQUISITION We performed a systematic literature analysis using the Ovid Medline database, encompassing English language studies (published between 1980 and 2018) reporting the natural history of untreated bAVMs. Annual hemorrhage rates in both unruptured and previously ruptured bAVMs, as well as risk factors for future hemorrhage were extracted for analysis. EVIDENCE SYNTHESIS Eighteen studies with a total of 8418 bAVM-cases could be extracted from the literature. Seventeen studies reported annual hemorrhage rates and ten studies reported risk factors for future hemorrhage. The average annualized hemorrhage rate was 2.2% for unruptured bAVMs and 4.3%, for bAVMs that presented with hemorrhage. Prior hemorrhage and deep AVM location could be identified as most consistently reported risk factors for future hemorrhage. CONCLUSIONS Previously ruptured bAVMs have a higher annual hemorrhage rate than unruptured bAVMs. Deep bAVM location and prior hemorrhage may increase the risk for subsequent hemorrhage.
Overview of Nonflammability Characteristics of Graphene and Graphene Oxide-Based Polymeric Composite and Essential Flame Retardancy Techniques

ABSTRACT The carbonaceous nanofillers such as graphene and graphene oxide play competent role due to fine structural and functional properties having wide range of technical applications. This paper reviews structure and flame-retardant properties of graphene and graphene oxide. These nanofillers form promising nanomaterials for next generation high-performance structural and multifunctional composite structures. One of the major difficulties to produce strong and thermally conductive graphene/graphene oxide composites is fine dispersion of carbon nanomaterials. Consequently main focus of review is on flame retardancy of organic filler-based nanocomposite. To the end, techniques for nonflammability property measurement of polymer/graphene and polymer/graphene oxide have been discussed. GRAPHICAL ABSTRACT
