Cannabis-related hospitalizations: unexpected serious events identified through hospital databases.

AIMS Cannabis is the most prevalent illicit drug used worldwide and can be responsible for serious health defects in users. However, the risk related to cannabis consumption is not well established. The present study aimed to assess cannabis-related adverse events leading to hospitalization, and to estimate the corresponding annual risk for consumers. METHODS Participants were patients admitted to the public hospitals in the Toulouse area (France) between January 2004 and December 2007 in relation to the use of cannabis. Reasons for admission and other occurring events were identified through hospital discharge summaries. We described all observed adverse events (AEs) and estimated their regional incidence on the basis of cannabis consumption data. RESULTS We included 200 patients, and identified a total of 619 adverse events (AEs), one of which was lethal. Psychiatric disorders involved 57.7% of patients and accounted for 18.2% of AEs. Most frequent outcomes were central and peripheral nervous system disorders (15.8% of AEs), acute intoxication (12.1%), respiratory system disorders (11.1%) and cardiovascular disorders (9.5%). We estimated that in 2007 the incidence of cannabis-related AEs in the Midi-Pyrenees region ranged from 1.2 per 1000 regular cannabis users (95% confidence interval (CI) 0.7, 1.6) to 3.2 (95% CI 2.5, 3.9). CONCLUSIONS Cannabis use is associated with complications, considered to be serious since they lead to hospitalization. Beyond the well-known and widely investigated psychiatric events, serious cerebro and cardiovascular complications have been identified. These findings contribute to improve the knowledge of cannabis-related adverse events.
The Paradoxes of Word of Mouth in Electronic Commerce

Abstract Challenging conventional wisdom, we unravel three paradoxes of word of mouth (WOM) in e-commerce. Specifically, the WOM valence paradox contends that higher WOM valence of a product results in a larger subsequent decrease in the WOM valence of the product, the WOM volume paradox propounds that higher WOM volume of a product results in a smaller subsequent increase in the WOM volume of the product, and the WOM spillover paradox proposes that an improvement in the WOM of a product also improves the WOM of connected products in a product network. These paradoxes caution online retailers that superior WOM may at times backfire and not boost further sales. Drawing theoretical support from expectation-confirmation theory and network theory, we collect data from China’s largest business-to-consumer platform, Tmall.com, and use linear panel data models to examine WOM evolution in a product network, controlling for relevant factors at the individual product, product network, and time unit levels. Importantly, we base our identification strategies on the use of instrumental variables and the difference-in-differences estimation approach. Numerous statistical checks confirm the robustness and consistency of our findings. We contribute to a much richer theoretical understanding of WOM, by extending the applicability of expectation-confirmation theory and network theory to novel predictions and contexts, adding a dynamic perspective, unveiling three important WOM paradoxes, and offering practical insights.
Pb, Nd, and Sr isotopic constraints on the origin of Miocene basaltic rocks from northeast Hokkaido, Japan: Implications for opening of the Kurile back‐arc basin

Late Miocene (7–9 Ma) basaltic rocks from the Monbetsu‐Kamishihoro graben in northeast Hokkaido have chemical affinities to certain back‐arc basin basalts (referred to herein as Hokkaido BABB). Pb‐, Nd‐ and Sr‐isotopic compositions of the Hokkaido BABB and arc‐type volcanic rocks (11–13 Ma and 4–4.5 Ma) from the nearby region indicate mixing between the depleted mantle and an EM II‐like enriched component (e.g. subducted pelagic sediment) in the magma generation. At a given 87Sr/86Sr, Hokkaido BABB have slightly lower 143Nd/144Nd and slightly less radiogenic 206Pb/204Pb compared with associated arc‐type lavas, but both these suites are difficult to distinguish solely on the basis of isotopic compositions. These isotopic data indicate that while generation of the Hokkaido BABB involves smaller amounts of the EM II‐like enriched component than do associated arc lavas, Hokkaido BABB are isotopically distinct from basalts produced at normal back‐arc basin spreading centers. Instead, northeast Hokkaido BABB are more similar to basalts erupted during the initial rifting stage of back‐arc basins. The Monbetsu‐Kamishihoro graben may have developed in association with extension that formed the Kurile Basin, suggesting that opening of the basin continued until late Miocene (7–9 Ma).
Mobile MicroRNAs Hit the Target

MicroRNAs (miRNAs) are negative regulators of gene expression in eukaryotic organisms, whereas small interfering RNAs (siRNAs) guide host‐cell defence against viruses, transposons and transgenes. A key issue in plant biology is whether miRNAs act only in cells in which they are formed, or if, like siRNAs, they also function after passive diffusion or active transportation into other cells. Recent reports show that miRNAs are indeed able to move between plant cells to direct developmental programming of gene expression. In both leaf and root development, miRNAs establish intercellular gradients of gene expression that are essential for cell and tissue differentiation. Gradients in gene expression also play crucial roles in animal development, and there is strong evidence for intercellular movement of miRNAs in animals. Thus, intercellular movement of miRNAs may be crucial to animal developmental biology as well as plants.
Stability of Subtilisin and Lysozyme under High Hydrostatic Pressure

The stabilities of subtilisin and lysozyme under hydrostatic pressures up to 200 MPa were investigated for up to 7 days at 25 °C. Methods were chosen to assess changes in tertiary and secondary protein structure as well as aggregation state. Tertiary structure was monitored in situ with second derivative UV spectroscopy and after pressure treatment by dynamic light scattering and second derivative UV spectroscopy. Secondary structure and potential secondary structural changes were characterized by second derivative FTIR spectroscopy. Changes in aggregation state were assessed using dynamic light scattering. Additionally, protein concentration balances were carried out to detect any loss of protein as a function of pressure. For the conditions tested, neither protein shows measurable changes in tertiary or secondary structure or signs of aggregation. Lysozyme concentration balances show no dependence on pressure. Subtilisin concentration balances at high protein concentration (4 mg/mL and higher) do not show pressure dependence. However, the concentration balances carried out at 0.4 mg/mL show a clear sign of pressure dependence. These results may be explained by protein interaction with the vial surface and appear to be rate limited by the equilibrium between active and inactive protein on the surface. Pressure increases protein loss, and the estimated partial molar volume change between the two states is estimated to be −20 ± 10 mL/mol.
Indirect effect of conjugate vaccine on adult carriage of Streptococcus pneumoniae: an explanation of trends in invasive pneumococcal disease.

BACKGROUND Use of heptavalent protein-polysaccharide pneumococcal conjugate vaccine (PCV7) has been associated with decreases in PCV7-type invasive pneumococcal disease and nasopharyngeal (NP) carriage in children. Vaccine use has also indirectly decreased the rate of invasive disease in adults, presumably through decreased transmission of pneumococci from vaccinated children to adults. METHODS We conducted NP carriage surveys in 8 villages in Alaska in 1998-2004. Streptococcus pneumoniae isolates were characterized by serotype and antimicrobial susceptibility. We analyzed trends in serotype distribution, antibiotic resistance, and factors associated with adult carriage of PCV7-serotype pneumococci before and after the introduction of PCV7 in 2001. RESULTS We collected 15,598 NP swabs; overall, 52% of adults living in the villages surveyed participated in the colonization study. The proportion of adult carriers with PCV7-type pneumococcal carriage decreased from 28% of carriers in 1998-2000 to 4.5% of carriers in 2004 (P<.0001). Among adults, the proportion of colonizing isolates that were resistant to penicillin decreased from 13% in 1998-2000 to 6% in 2004 (P=.05), whereas the percentage of isolates with intermediate susceptibility to penicillin increased from 12% in 1998-2000 to 19% in 2004 (P<.01). Adults were more likely to carry PCV7-type pneumococci if they lived with a child <5 years old or if they lived with a child who had not been age-appropriately vaccinated with PCV7. CONCLUSIONS Pediatric vaccination with PCV7 has resulted in decreased PCV7-type pneumococcal carriage among adults and helps to explain recent decreases in the rate of PCV7-type invasive pneumococcal disease among adults.
Statistical Modeling of the Number of Deaths of Children in Bangladesh

Efforts to reduce the number of children's death in developing countries through health care programs focus more to the prevention and control of diseases than to determining the underlying risk factors/predictors and addressing these through proper interventions. This study aims to identify socioeconomic and demographic predictors of the number of children's death to women aged 12-49 from the Bangladesh Health and Demographic Survey (BDHS) administered in 2011. The number of children's death in a family is a non-negative count response variable. The average number of children's death is found to be 28 per 100 women with a variance of 44per 100 women. Thus Poisson regression model is not a proper choice to predict the mean response from the BDHS data due to the presence of over-dispersion. In order to address over-dispersion, we fit a Negative Binomial Regression (NBR), a Zero-Inflated Negative Binomial Regression (ZINBR) and a Hurdle Regression (HR) model. Among these models, ZINBR fits the data best. We identify respondent's age, respondent's age at 1 st birth, gap between 1 st birth and marriage, number of family members, region, religion, respondent's education, husband's education, incidence of twins, source of water, and wealth index as significant predictors for the number of children's death in a family from the best fitted model. Identification of the risk factors of the number of children's death is an important public health issue and should be carried out correctly for the much needed intervention.
Influence of SDZ RAD vs. MMF on gastric emptying in renal transplant recipients

SDZ RAD and mycophenolate mofetil (MMF) are increasingly used in the prevention of renal allograft rejection. SDZ RAD, having a macrolide structure, and MMF, known with gastrointestinal side‐effects, may have gastric motility modifying properties. Gastric emptying was examined 1 yr after renal transplantation in eight patients taking corticosteroids (CS), cyclosporin A (CsA) and SDZ RAD and six patients treated with CS, CsA and MMF. Comparing the two groups, no significant differences in gastric emptying of solids and liquids were noted. Compared with normal volunteers, solid gastric emptying was faster in the SDZ RAD group and similar in the MMF group. It is concluded that in stable renal transplant recipients treated with MMF, gastric emptying was normal. Because of the impact on drug absorption and gastrointestinal symptoms, further studies are indicated to corroborate the potential prokinetic properties of SDZ RAD.

Diastolic dysfunction and natriuretic peptides in systolic heart failure. Higher ANP and BNP levels are associated with the restrictive filling pattern.

BACKGROUND Left ventricular diastolic dysfunction is common in patients with systolic heart failure and the restrictive type of filling pattern appears to be associated with increased cardiac mortality. Both artrial and brain (or ventricular) natriuretic peptides are also proven markers of the severity of heart failure. The aim of this study was to determine in a large cohort of patients with systolic heart failure whether diastolic abnormalities, and in particular the restrictive filling pattern of transmitral flow velocity, correlate with plasma atrial and brain natriuretic peptide levels. METHODS Sixty-eight consecutive patients with symptomatic systolic heart failure (ejection fraction < 0.5) underwent two-dimensional Doppler echocardiography of left ventricular systolic and diastolic function, together with measurement of atrial and brain natriuretic peptides. RESULTS The restrictive filling pattern was present in 62%, the abnormal relaxation pattern in 31% and only 7% were normal. Atrial and brain natriuretic peptide (ANP/BNP) levels were significantly higher in the restrictive compared to the abnormal relaxation group (ANP: 202.2 +/- 31.7 vs 102.5 +/- 22.1 pg.ml-1, P = 0.012; BNP: 277.8 +/- 27.7 vs 162.4 +/- 21.9 pg.ml-1, P = 0.002). In addition, a restrictive filling pattern was associated with lower ejection fractions (P = 0.026), higher pulmonary artery systolic pressure (P < 0.001), larger left atrial size (P = 0.044), and were more likely to be in New York Heart Association class III or IV than those with an abnormal relaxation pattern (P = 0.007). Both atrial and brain natriuretic peptides correlated inversely with ejection fraction (P < 0.001), fractional shortening (P < 0.001), and positively with pulmonary artery pressure (P = 0.004 and 0.001 respectively). There were no significant correlations between single diastolic parameters and atrial or brain natriuretic peptide levels for the total patient group except between mitral peak A wave velocity and brain natriuretic peptides (r = -0.3, P = 0.01). For those with abnormal relaxation pattern mitral, valve E-wave deceleration time correlated significantly with both atrial and brain natriuretic peptide levels (P < 0.01). CONCLUSIONS This study confirms that the restrictive filling pattern of transmitral flow velocity is a marker of more severe heart failure, as indicated by its association with higher atrial and brain natriuretic peptide levels, lower ejection fraction and higher pulmonary artery pressure. Thus, this easily obtained Doppler-derived marker of diastolic dysfunction is useful for identifying those patients with more severe heart failure.
Pathognomonic radiological signs for predicting prognosis in patients with chronic atlantoaxial rotatory fixation.

OBJECT The authors conducted a study to assess the correlation between radiological features and clinical courses in patients with chronic atlantoaxial rotatory fixation (AARF) and to determine diagnostic imaging signs for predicting prognosis. METHODS There were 24 patients (eight boys and 16 girls) whose mean age was 7.8 years (range 4-14 years) and in whom AARF was diagnosed. The mean follow-up duration was 3.7 years (range 5 weeks-12 years). There were two groups of patients: 15 patients who visited the hospital less than 8 weeks after symptom (torticollis) onset comprised the acute group, and nine patients in whom the diagnosis of AARF was established later than 3 months after symptom onset comprised the chronic group. The chronic group was divided into two subgroups: those in whom the closed reduction could be achieved and those in whom it could not. Clinical data and radiographic studies, including plain radiographs and plain and three-dimensional (3D) computed tomography (CT) reconstructions, were reviewed retrospectively. A deformity of the superior C-2 facet joint was frequently observed in the group of patients with chronic AARF (p < 0.0001). This sign represented a risk factor for recurrent dislocation (p = 0.0003, Fisher exact test). Prominent lateral inclination of C-1 was an impeding factor for reduction of chronic AARF (p < 0.0001, analysis of variance with Fisher post hoc test). Greater than 20 degrees of lateral inclination of the atlas indicated an irreducible subluxation (p = 0.0023, Fisher exact test). CONCLUSIONS Both facet joint deformity and lateral inclination observed on 3D CT reconstructions can be useful signs to predict the prognosis and the treatment of choice in patients with chronic AARFs.
Neural plasticity and the limits of scientific knowledge

Western science claims to provide unique, objective information about the world. This is supported by the observation that peoples across cultures will agree upon a common description of the physical world. Further, the use of scientific instruments and mathematics is claimed to enable the objectification of science. In this work, carried out by reviewing the scientific literature, the above claims are disputed systematically by evaluating the definition of physical reality and the scientific method, showing that empiricism relies ultimately upon the human senses for the evaluation of scientific theories and that measuring instruments cannot replace the human sensory system. Nativist and constructivist theories of human sensory development are reviewed, and it is shown that nativist claims of core conceptual knowledge cannot be supported by the findings in the literature, which shows that perception does not simply arise from a process of maturation. Instead, sensory function requires a long process of learning through interactions with the environment. To more rigorously define physical reality and systematically evaluate the stability of perception, and thus the basis of empiricism, the development of the method of dimension analysis is reviewed. It is shown that this methodology, relied upon for the mathematical analysis of physical quantities, is itself based upon empiricism, and that all of physical reality can be described in terms of the three fundamental dimensions of mass, length and time. Hereafter the sensory modalities that inform us about these three dimensions are systematically evaluated. The following careful analysis of neuronal plasticity in these modalities shows that all the relevant senses acquire from the environment the capacity to apprehend physical reality. It is concluded that physical reality is acquired rather than given innately, and leads to the position that science cannot provide unique results. Rather, those it can provide are sufficient for a particular environmental setting.
In vivo and in vitro binding of carbon tetrachloride with nucleic acids and proteins in rat and mouse liver

14C‐labelled carbon tetrachloride binds in vivo to DNA of mouse liver and to rRNA of rat liver if the animals have been pretreated with 3‐methylcholanthrene. A noticeable amount of radioactivity is also observed in liver proteins. In vitro carbon tetrachloride is activated by microsomes and pH 5 enzymes of 3‐methylcholanthrene‐treated animals to a metabolite which can react with DNA and polynucleotides; this effect is more evident if subcellular fractions from mouse liver are used.
A Profile of OxyContin Addiction

Abstract OxyContin is a controlled-released form of oxycodone indicated for the management of moderate to severe pain. OxyContin diversion and abuse has become a major problem in certain areas of the United States, particularly rural areas and Appalachia. This study undertakes an 18-month retrospective chart review at a private freestanding psychiatric facility to develop a profile of OxyContin addicts seeking treatment. There were 579 admissions to the Addictive Disease Unit of this facility from October 2000 to March 2002, with 298 of these admissions being for the treatment of opioid abuse or dependence. One hundred and eighty-seven of these individuals were dependent on OxyContin, using an average dose of 184 milligrams of OxyContin per day. The OxyContin-dependent individuals tended to show a progression from p.o. use to either snorting or i.v. use. The author concludes that a socio-cultural understanding is needed to better treat these addicts as is improved communication between the pain treatment community and the addiction treatment community.
Studies on Bacillus subtilis, as Potential Probiotics, on the Biochemical Parameters of Rainbow trout, Oncorhynchus mykiss (Walbaum) to Challenge Infections

In this study Bacillus subtilis is used for control of streptococcosis with the agent of Streptococcus iniae in Rainbow trout. The experience was carried out in 2 groups (Control and Treatment) and 3 replicates. In Control group, probiotic was not applied in diet but in Treatment group, Bacillus subtilis was administered in feed at a concentration of 10 7 cells g -1 . In the day of forty five, 0.1 ml intraperitoneally injection of S.iniae with 2×10 7 cells ml -1 dosage was done for both of groups and were checked for the rest of the survey duration (2 weeks). At the end of the time which took about two months, blood samples were caught for biochemical experiments for realizing the effect of B.subtilis feeding on resistance of fish against S.iniae infection. After injection of S.iniae, there was no significant difference among Control(C) and Treatment(T) groups considering parameters such as glucose and aspartate aminotransferase (p>0.05). But significant difference was seen in the serum total protein, serum albumin, IgM, lysozyme,
Terahertz photoconductive antenna efficiency

Terahertz (THz) photoconductive antennas are the most common device for the generation and detection of THz waves and are very different from conventional RF/microwave antennas. One of the major problems of the current photoconductive antennas is that the antenna efficiency is very low, thus it is difficult to obtain high power THz waves. In this paper a comparison of the conventional and photoconductive antennas is made and various parameters and aspects of photoconductive antennas are examined with the aim to maximise its efficiency factor. A new antenna efficiency expression is derived which clearly shows how the efficiency is linked to various parameters. An example is used to demonstrate why the total efficiency is very low and what the major limiting factors are. Recommendations for how to increase the efficiency are presented.
Design and Initial Performance of the COSINE-100 Experiment

COSINE is a dark matter search experiment based on an array of low background NaI(Tl) crystals located at the Yangyang underground laboratory. The assembly of COSINE-100, the Phase-I version of the experiment, was completed in the summer of 2016 and the detector is currently collecting physics quality data aimed at reproducing the DAMA/LIBRA experiment that reported an annual modulation signal. Stable operation has been achieved and will continue for at least two years. Here, we describe the design of COSINE-100, including the shielding arrangement, the configuration of the NaI(Tl) crystal detection elements, the veto systems, and the associated operational systems, and we show the current performance of the experiment.
