Cannabis use disorder and post-traumatic stress disorder: The prevalence of comorbidity in veterans of recent conflicts

Aims: Veterans have high rates of cannabis use, and rates of cannabis use disorder (CUD) are rising among this population. These rising rates are particularly true for veterans with post-traumatic stress disorder (PTSD), which is common among veterans of recent conflicts, Operations Enduring Freedom, Iraqi Freedom, and Operation New Dawn (OEF/OIF/OND). Although prior work has documented links between PTSD and cannabis use, a better understanding of the intersection among CUD, PTSD, and other disorders in real-world clinical practice can inform prevention and treatment efforts. This study examined the prevalence and comorbidities of CUD and PTSD in OFE/OIF/OND veterans. Method: The study analyzed data from the Veterans Affairs Corporate Data Warehouse (2010-2016) for returning war veterans who were diagnosed with CUD (N = 46,268). The study determined prevalence of PTSD, and examined additional differences in comorbidities. Results: The prevalence of a comorbid PTSD diagnosis among OEF/OIF/OND veterans with a CUD diagnosis was 72.3%. Further analysis revealed additional co-occurring disorders. Veterans with a diagnosis of CUD and PTSD were more likely to have a comorbid diagnosis of depression (odds ratio, 1.69; 95% CI, 1.62-1.71), panic disorder (odds ratio; 1.58; 95% CI, 1.43-1.75), alcohol use disorder (odds ratio; 1.30; 95% CI, 1.24-1.35), opioid use disorder (odds ratio; 1.52; 95% CI, 1.43-1.62), and insomnia (odds ratio; 1.74; 95% CI, 1.65-1.84) than veterans without a PTSD diagnosis. Conclusions: Findings highlight that the majority of returning war veterans with CUD are highly complex. Our findings substantiate the need for urgent, comprehensive care for veterans with co-occurring CUD and PTSD, including integrated and transdiagnostic treatment approaches.

Rapid removal of nitrate from liquid dairy manure by cationic poly (vinyl alcohol-co-ethylene) nanofiber membrane

Elevated levels of nitrate in surface water is a leading concern, which impacts human and animal health, and controlling it requires improved and sustainable methods capable of removing nitrate anions from source waste water to reduce nitrate anions transport to environment. In liquid dairy manure, nitrogen content can vary from 200 to 600 ppm and the transport of manure nitrogen into ambient water through hydrologic processes has a potential to exceed the maximum contaminant level limit (10 ppm) of nitrate nitrogen for regulated public water systems. Dairy manure is considered as a reservoir of nitrate. This research investigates on the determination of optimal designing of nanofiber membrane to remove nitrate anions from liquid dairy manure. A cationic poly (vinyl alcohol-co-ethylene) nanofiber membrane (EVOH) NFM was grafted via UV with 2-(methacryloyloxy) ethyl trimethylammonium chloride (DMAC) monomers. The adsorption efficiency of nitrate by the membrane was determined on liquid manure of dairy lagoons located in Central Valley of California. Initial nitrate concentrations in dairy manure varied from 75 to 100 ppm. Results showed that nitrate in dairy water was removed by 70% in 40 min. Tortuous structure and chemical stability of membrane resulted in nitrate dynamic binding capacity of 40 mg g(-1). Furthermore, it exhibits efficient reusability without significant changes in its performance using 0.5 M sodium hydroxide solution for nitrate desorption. Results showed that change in pH, and multi-anion conditions had limited effects on nitrate removal efficiency, and EVOH NFM can be a viable option to remove nitrate of liquid manure. This could be used for mitigating transport of excess nitrate from manure to environment. Overall, the results suggest that EVOH-g-DMAC NFM is efficient, low-cost (13 USD/m(3)) and recyclable material for sustainable removal of nitrate from dairy manure wastewater without requiring any ionic strength or pH adjustment.

Nitrogen metabolism in three non-conventional wine yeast species: A tool to modulate wine aroma profiles

The positive impact of certain non-Saccharomyces yeasts on the aromatic profile of wines has been well documented in literature and their industrial use in association with S. cerevisiae is now recommended. Competition between non-Saccharomyces species and Saccharomyces cerevisiae for various nutrients, especially nitrogen sources, greatly impacts the production of aroma compounds. In this study, we further explored the impact of different nitrogen nutrition strategies on the production of carbon and sulphur volatile compounds of three nonSaccharomyces strains, namely Pichia burtonii, Kluyveromyces marxianus, Zygoascus meyerae sequentially inoculated with S. cerevisiae in Sauvignon blanc and Shiraz grape musts. Nitrogen additions were implemented according the specific requirement of each species. At the end of fermentation, we observed specific metabolic signatures for each strain in response to the nature of the nitrogen source suggesting strain-specific metabolic fluxes present. Overall, these results confirmed and further explored the interconnection between nitrogen sources and aroma metabolism (including that of higher alcohols, fatty acids, esters and volatile sulphur compounds), and their variations according to species and the nature of the nitrogen source. The knowledge generated provides new insights to modulate the aroma profile of wines produced with non-Saccharomyces species.

Independent association of marijuana use and poor oral hygiene with HPV-negative but not HPV-positive head and neck squamous cell carcinomas

Background Sexual behavior is associated with human papillomavirus (HPV)-positive head and neck cancer, whereas tobacco and alcohol use are associated with HPV-negative cancer. A case-control study was designed to investigate additional demographic and behavioral factors independently associated with these distinct oral cancers. Methods From 2011 to 2014, 249 newly diagnosed oral cavity and oropharyngeal squamous cell carcinoma (OSCC) cases were matched (1:2) on age, gender, and self-identified race to 498 controls without a cancer history attending the outpatient otolaryngology clinic at The Ohio State University in Columbus. Cases were stratified by detection of high-risk HPV DNA and RNA in tumors. Demographic and behavioral data were collected using an audio computer-assisted self-interview, and associations with HPV-positive versus HPV-negative OSCCs were investigated by use of univariable and multivariable conditional logistic regression models. Results After adjustment for oral sexual behavior, the odds of HPV-positive cancer decreased with the patient’s years of education. Annual income, tobacco smoking, alcohol drinking, marijuana smoking, and poor oral hygiene were not associated with HPV-positive OSCC. In contrast, the odds of HPV-negative OSCC increased independently with decreased annual income, decreased with a high number of marijuana hit-years, and increased with fewer than annual dental visits after adjustment for lifetime tobacco and alcohol use. Sexual behavior and education were not associated with HPV-negative OSCC. Conclusions The distinct risk-factor profiles for HPV-positive and HPV-negative OSCC are confirmed and extended in this case-control study, thus supporting 2 principal etiological pathways for OSCC development. Lay Summary Sexually acquired human papillomavirus (HPV) infection is an established cause of tonsil and base of tongue cancers. This study compared and contrasted risk factors for HPV-positive and HPV-negative oral cancers. Low number of years of education and sexual behavior are associated with HPV-positive cancer. In contrast, low annual income, infrequent dental visits, and tobacco and alcohol use are associated with HPV-negative cancers. Long-term marijuana use appears protective for HPV-negative cancer. Public health efforts to address these modifiable risk factors may prevent oral cancer.

Immunomodulatory and Antimicrobial potential of ethanolic extract of Himalayan Myrica esculanta in Oncorhynchus mykiss: Molecular modelling with Aeromonas hydrophila functional proteins

The present study was carried out to investigate the antimicrobial and immunomodulatory activity of Myrica esculenta ethanolic leaf extract (MeALE) in rainbow trout. The juvenile fish were immersed in 20 mg/l (T1) and 40 mg/l (T2) MeALE for 2 and 6 h and then challenged with pathogenic bacteria, A. hydrophila (ATCC 7966, USA) after 6 h post immersion in MeALE. The immuno-haematological parameters and relative percentage survival were recorded over 7 days post-exposure. The amino acid interaction of functional proteins of bacteria with myricetin, the active ingredient of M. esculenta was performed by AutoDock Vina software. FTIR detected the characteristic peak values and revealed the presence of various functional groups, viz. alkenes, amines, alcohols, phenols and aromatic compounds. The MIC of MeALE was found to be 2 mg/ml while MBC was recorded to be 25 mg/ml. Molecular docking revealed a strong affinity between myricetin and functional proteins of the pathogen. The fish immersed in 40 mg/l MeALE showed a significant increase in haematological indices and non-specific immunological parameters. The current study reports the successful use of MeALE as an antimicrobial and immunostimulatory agent in rainbow trout and recommends the dosage of 40 mg/l MeALE for preventing Aeromonas infection.

Stability of Posttreatment Reductions in World Health Organization (WHO) Drinking Risk Levels and Posttreatment Functioning in Older Adults with DSM-5 Alcohol Use Disorder: Secondary Data Analysis of the Elderly Study

Background Studies have found that reductions in World Health Organization (WHO) drinking risk levels may be a stable outcome of treatment for alcohol use disorder (AUD) and associated with functional improvements. The aim of this study was to investigate whether posttreatment reductions in WHO drinking risk levels are stable over time among older adults and associated with a decrease in consequences of drinking and AUD symptoms and improved quality of life. Methods Participants. Individuals 60+ years old, suffering from DSM-5 AUD (n = 693), and seeking outpatient treatment. Measurements. WHO drinking risk levels, prior to treatment and at all follow-up points up to 1 year after treatment start, were assessed with Form 90. Outcomes at follow-up included consequences of drinking (Drinker Inventory of Consequences), quality of life (WHOQOL-BREF), and DSM-5 AUD symptoms (Mini International Neuropsychiatric Interview). Logistic regression and linear mixed models were used to examine the probability of maintaining risk-level reductions at follow-up and the association between risk-level reductions and outcomes, respectively. Results Reductions in risk levels were maintained over time (at least 1 level: OR 5.39, 95% CI 3.43, 8.47; at least 2 levels: OR 9.30, 95% CI 6.14, 14.07). Reductions were associated with reduced consequences of drinking and number of AUD symptoms, and minor, but statistically significant, improvements in quality of life. Conclusions Maintaining reductions in WHO risk levels appears achievable for older adults seeking treatment for AUD. The small reduction of AUD symptoms and improvement of quality of life indicates that these reductions may not be adequate as the only treatment goal.

Electrocatalytic methane oxidation on Co3O4- incorporated ZrO2 nanotube powder

The activation of methane (CH4) gas to produce more valuable liquid hydrocarbons has long been a challenging issue in catalytic research. Electrochemical oxidation is one of the main methods of methane activation and can usually proceed at in ambient temperature. However, the lack of efficient electrocatalysts limits the practical application of this strategy. In this study, ZrO2 nanotube powder with a high specific surface area was decorated with Co3O4 nanoparticles and used as the electrochemical anode for the partial oxidation of methane to generate C3 alcohol products. The Co3O4 nanoparticles formed on outer the surface of the ZrO2 nanotubes offer an accessible diffusion route for methane gas, resulting in a low onset potential for electrochemical methane activation. A high production rate of approximately 2416 mu mol g(cat)(-1) h(-1) was obtained at 1.6 V (vs RHE) after 12 h of reaction. This nanostructure engineering strategy contributes to the enhancement of catalytic activity for electrochemical methane oxidation with the production of higher alcohols, which could provide a new catalyst synthesis strategy for researchers.

Hydrogen solubility in bio-based furfural and furfuryl alcohol at elevated temperatures and pressures relevant for hydrodeoxygenation

Biomass conversion into fuels and added-value chemicals, in high yield and with good selectivity, is still a great issue and an attractive research topic. The design and the optimization of defunctionalisation processes require accurate kinetic models that take into account the solubility of various gases in the bio-based chemicals present in the process. Some of the promising platform bio-based compounds that can be further converted to valuable chemicals are furfural and furfuryl alcohol. Hydrogen solubility in furfural and furfuryl alcohol was studied at three temperatures from the range (323.15-423.15) K and at pressures up to 25 MPa. Hydrogen dissolves better in furfural than in furfuryl alcohol, for about 15 %. The obtained experimental data were modelled using the Soave-Redlich-Kwong and Peng-Robinson cubic equations of state, as well as the PC-SAFT equation of state. The parameters of the PC-SAFT equation of state for pure compounds were defined for furfural and furfuryl alcohol. The binary interaction parameters, crucial for the prediction of phase-equilibrium behaviour, were determined for both examined systems. The interaction parameters obtained for the cubic equations of state were temperature dependent, while the interaction parameters optimized for the PC-SAFT equation of state were almost the same at all three temperatures for each studied system. The average absolute percentage deviations between the measured equilibrium pressures and those calculated using the mentioned models were under 4 %.

Thermochemical liquefaction of cattle manure using ethanol as solvent: Effects of temperature on bio-oil yields and chemical compositions

Cattle manure was converted into bio-oil via suband super-critical liquefaction with ethanol as the solvent. The effects of various reaction parameters, including the reaction temperature (T, 180-300 degrees C), solid-liquid ratio (S-1, 5-15%), and solvent filling ratios (S-2, 10-30%) on the yield of bio-oil (OCM) and residue (RCM) from liquefaction of cattle manure were studied. The yield of bio-oil was positively correlated to reaction temperature suggesting higher reaction temperature could promote the fragmentation of the polymers transformed into a liquid oil-rich phase and the maximum OCM relative yield (32.14 +/- 0.19%) was obtained at 300 degrees C. OCM had HHV of 25.63-33.41 MJ/kg and LHV of 23.85-31.39 MJ/ kg, respectively, suggesting their potential for use as a renewable energy to replace fossil energy. The GC-MS analyses demonstrated that the major compounds in OCM were esters, hydrocarbons, alcohols, phenolic compounds, nitrogenous and bromine components, the compositions of OCM was similar to that of biodiesel. The presence of ester compounds in OCM which was attributed to the degradation of cellulose and hemicelluloses. Carbon-normal paraffin gram (C-NP) analysis indicated that C-18 and C-20 species comprised the bulk of the hydrocarbon compounds from OCM. (c) 2020 Elsevier Ltd. All rights reserved.
