Cannabis and cannabinoids for persistent pain?

Over the last 12 months New Zealanders have entered into the debate about cannabis and cannabinoids for medical use. In the coming year we’ll hear even more about cannabis as we consider legalising cannabis for recreational use. There is so much rhetoric around the issue, and so much misinformation I thought it high time (see what I did there?!) to write about where I see the research is at for cannabis and cannabinoids for persistent pain. For the purposes of this blog, I’m going to use the following definitions: Cannabis = the plant; cannabis-based medication = registered extracts (either synthetic or from the plant) in standardised quantities with quality assurance; cannabinoids = substances found in cannabis that may or may not be synthesised into cannabis-based medication. I’m going to divide this post into two: one part is about cannabis and cannabis-based medication for persistent pain; and the other is about cannabis for recreational purposes. Recreational use Cannabis is really popular in New Zealand. Growing up in Gisborne, one of the prime growing regions because of its long, warm summers, cannabis was common. I’ll put my hand on my heart and say I didn’t try it because I was a bit of a nerd and didn’t even try alcohol until I’d left home at 17! Ministry of Health estimates that eleven percent of adults aged 15 years and over reported using cannabis in the last 12 months (defined here as cannabis users). Can...

However, the clinical use of zinc(II) complexes is hampered by hydrolytic insolubility and poor bioavailability and their anticancer mechanisms remain unclear. Here, we investigated the efficacy and mechanism of action of a polyvinylpyrrolidone (PVP-k30)-based solid dispersion of Zn(II)-curc...

HPV DNA detection in urine samples of women: "An efficacious and accurate alternative to cervical samples?" Expert Rev Anti Infect Ther. 2019 Sep 13;: Authors: Pattyn J, Van Keer S, Téblick L, Van Damme P, Vorsters A Abstract Cervical cancers are caused by persistent human papillomavirus (HPV) infections [1]. To date, HPV DNA testing using clinician-obtained cervical cells is the reference for identifying cervical infection. However, great interest has been shown for the use of self-sampling methods to detect HPV [2]. One method for self-sampling to be considered is the collection of f...

ConclusionsPRDR radiation therapy with capecitabine were well tolerated and effective method for treating patients with recurrent breast cancer. Prospective studies are necessary to compare side effects and efficacy with conventional dose rate re-irradiation, as well as, to evaluate the potential role for capecitabine in the recurrent setting.

Conclusion: Specific contexts appeared to be associated with problematic drinking for both sexes. Among both men and women, "social drinking" was associated with problematic drinking. Both "home drinking" (men) and "daytime drinking" (women) contexts, were associated with problematic drinking and depressive symptoms. Targeted alcohol-focused interventions need to address co-occurring mental health issues. PMID: 31519127 [PubMed - as supplied by publisher]

Conclusions/Importance: The ARC has substantial weaknesses in its theoretical alignment, item performance, and psychometric properties with diverse populations. We recommend the development of a new multidimensional, theory-aligned measure, following a rigorous measurement development protocol. PMID: 31519121 [PubMed - as supplied by publisher]

Conclusions: Women with deep invasive endometriosis who underwent IVF do not seem to be exposed to a substantially increased risk of recurrence/disease progression. Larger evidence from independent groups is however required for a definitive conclusion. PMID: 31517304 [PubMed]

Conclusions: A wide variety of analgesia protocols are used. The three most frequently used are i.v. administered opioids, i.m. administered opioids, and non-sedative oral analgesics. The variety of analgesia protocols is not desirable in the context of good clinical practice, and considering the risks of combining opioids and benzodiazepines. Monitoring of vital functions was only performed after administration of i.v. medication. A comparison of the pain scores could be a first step in finding the optimal method of analgesia, thereby forming the basis of guidelines for analgesia during oocyte retrieval.

to AE Abstract Walnut fruit (Juglans regia L.) is an internationally well-known product with an important tradition of consumption. Its health benefits and economic importance in the food industry make this nut an interesting research topic. In this feasibility study, 200 walnut samples of 5 different varieties were collected and their near infrared (NIR) spectra were recorded with 3 different devices: a benchtop Fourier transform near infrared (FT-NIR) spectrograph, a dispersive hyperspectral imaging camera and a portable NIR dispersive spectrograph. Discriminant analyses were applied and different methods for th...
