This study examined associations of mental health treatment use and perceived treatment need with cannabis use characteristics (medical vs. nonmedical use, initiation age, use frequency, and cannabis use disorder) among past-year cannabis users aged 50+.
 
  Data came from the 2015-2019 National Survey of Drug Use and Health (N = 44,007). After comparing past-year cannabis users with nonusers and nonmedical users with medical users on sociodemographic and health-related factors, the research questions were examined with logistic regression models.
 
  In addition to mental disorders, medical use, compared to nonmedical use, was associated with higher odds of psychotherapeutic prescription medication use (AOR = 1.47, 95 % CI = 1.07-2.01) and any mental health treatment (prescription medication, outpatient care and/or inpatient care) (AOR = 1.51, 95 % CI = 1.13-2.03). Compared to 1-29 days of use, nonmedical users who used on 100-199 days (AOR = 0.60, 95 % CI = 0.40-0.89) and medical users who used on 200-365 days to receiving professional care.The mollusk shells present distinctive microstructures that are formed by small amounts of organic matrices controlling the crystal growth of calcium carbonate.  https://www.selleckchem.com/products/b102-parp-hdac-in-1.html  The shell of Pinctada fucata has the prismatic layer consisting of prisms of single calcite crystals and the nacreous layer consisting of aragonite tablets. The calcite crystal of prisms contains small angle grain boundaries caused by a dense intracrystalline organic matrix network to improve mechanical strength. Previously, we identified chitin and chitinolytic enzymes as components of this intracrystalline organic matrix. In this study, to reveal the function of those organic matrices in calcium carbonate crystallization, calcites synthesized in chitin gel with or without chitinolytic enzymes were analyzed by using transmission electron microscope (TEM) and atom probe tomography (APT), showing ion clusters derived from chitin inside of a calcite and small angle grain boundaries at optimal chitinolytic concentration. Furthermore, we performed the experiment in which chitinase inhibitor was injected into a living P. fucata. Nanoindentation and electron back scattered diffraction (EBSD) show that mechanical properties and crystal orientation were changed. These results suggested that chitinolytic enzymes work cooperatively with chitin to regulate the crystal growth and mechanical properties of the prismatic layer.The patient's security and safety represent a topic of great importance for public health that led several healthcare organizations in many Countries to share documents to promote risk management and preventing adverse events. Surgical Fire (SF) is an infrequent adverse event generally occurring in the operating room (OR) and consisting of a fire that occurs in, on, or around a patient undergoing a medical or surgical procedure. Here a medico-legal case involving a 65-year-old woman reporting burns to the neck due to an SF during a thyroidectomy was described. A literature review was performed using Pubmed and Scopus databases, focusing on epidemiology, causes, prevention activities associated with the SF, and the related best practices recommendations. The medico-legal analysis of the case led to admit the professional liability because the suggested time (3 min) to use the electrocautery after CHG application was not respected. The case analysis and the literature review suggest the importance of implementing National and Local procedures to promote the management of SF risk. Finally, it is necessary to highlight the role of incident reporting and root causes analysis in understanding the cause of the adverse events and thus enforce their prevention.A vegetated drainage ditch (VDD) system is an effective management practice for removing excess phosphorus (P) from agricultural runoff. However, the maximization of P removing efficiency by VDD remains a challenge. In this study, new VDDs with akadama clay barriers (particle size of clay 1-6 mm; height of barrier 5-15 cm and length of barrier 10-90 cm) were designed in lab scale, and the mechanism of phosphate removal by akadama clay was investigated. It was found that a new VDD with akadama clay barriers (particle size1 mm; height10 cm and length 90 cm) exhibited the highest removal efficiency of total P (TP) (97.1%), particulate P(PP) (96.9%), and dissolved P (DP) (97.4%), respectively. The retained P was mainly adsorbed in akadama clay barrier sections, and a low concentration of P was observed in soil sections in the new VDD. The maximum adsorption capacity of phosphate to akadama clay was 5.06 mg/g at 298 K, and XPS analysis indicated that phosphate was adsorbed by the inner-sphere complexation formation with the metal elements (Al, Fe). This study indicates that the new VDD with akadama clay barriers is a promising technique to efficiently remove P from agricultural runoff and significantly minimize the risk of P release into streams through runoff.NH3 and greenhouse gases emission are big problems during composting, which can cause great nitrogen nutrient loss and environmental pollution. This study investigated effects of the porous bulking agent of oil shale semicoke and its activated material on the gases emission during the continuous thermophilic composting. Results showed addition of semicoke could significantly reduce the NH3 emission by 74.65% due to its great adsorption capacity to NH4+-N and NH3, further the effect could be enhanced to 85.92% when utilizing the activated semicoke with larger pore volume and specific surface area. In addition, the CH4 emission in the semicoke and activated semicoke group was also greatly mitigated, with a reduction of 67.23% and 87.62% respectively, while the N2O emission was significantly increased by 93.14% and 100.82%. Quantification analysis of the functional genes found the abundance of mcrA was high at the massive CH4-producing stage and the archaeal amoA was dominant at the N2O-producing stage in all the composting groups. Correlation and redundancy analysis suggested there was a positive correlation between the CH4 emission and mcrA. Addition of semicoke especially activated semicoke could reduce the CH4 production by inhibiting the methanogens. For the NH3 and N2O, it was closely related with the nitrification process conducted by archaeal amoA. Addition of semicoke especially activated semicoke was beneficial for the growth of ammonia-oxidizing archaea, causing the less NH4+-N transformation to NH3 but more N2O emission.
