The sunflower seed is the seed of the sunflower (Helianthus annuus). The methanol extract of seeds of Helianthus annuus were screened for analgesic activity in mice model to systematically explore the medicinal values of the plant. Acetic acid induced writhing and hot plate methods were used to confirm the central and peripheral analgesic action. In case of acetic acid-induced writhing test the extract showed significant (P <0.05) analgesic potential at doses 100 and 200 mg/kg body weight (50.35 (...) and 57.85% inhibition, respectively). In the hot plate method, increase (p < 0.05) of latency period was also observed in comparison to standard aspirin. At 60 minutes, the latency period of two different doses (100 and 200 mg/kg body weight) was found at 13 ± 0.91 and 16.5 ± 1.55 second. The results obtained support the use of Helianthus annuus seeds in painful conditions acting both centrally and peripherally. (shrink)

There has been much debate regarding the 'double-effect' of sedatives and analgesics administered at the end-of-life, and the possibility that health professionals using these drugs are performing 'slow euthanasia.' On the one hand analgesics and sedatives can do much to relieve suffering in the terminally ill. On the other hand, they can hasten death. According to a standard view, the administration of analgesics and sedatives amounts to euthanasia when the drugs are given with an intention to hasten death. In this (...) paper we report a small qualitative study based on interviews with 8 Australian general physicians regarding their understanding of intention in the context of questions about voluntary euthanasia, assisted suicide and particularly the use of analgesic and sedative infusions (including the possibility of voluntary or non-voluntary 'slow euthanasia'). We found a striking ambiguity and uncertainty regarding intentions amongst doctors interviewed. Some were explicit in describing a 'grey' area between palliation and euthanasia, or a continuum between the two. Not one of the respondents was consistent in distinguishing between a foreseen death and an intended death. A major theme was that 'slow euthanasia' may be more psychologically acceptable to doctors than active voluntary euthanasia by bolus injection, partly because the former would usually only result in a small loss of 'time' for patients already very close to death, but also because of the desirable ambiguities surrounding causation and intention when an infusion of analgesics and sedatives is used. The empirical and philosophical implications of these findings are discussed. (shrink)

Despite analgesic and emetogenic benefits, cannabis has been banned from prescription in a number of western countries. Although some benefits are shared by drugs already available, the options of prescription are limited to the physician. The negative side-effects of cannabis do not justify this limitation on freedom and autonomy. Recreational use warrants limitations, as the search for euphoria is regularly believed to be a non-autonomous behavior. Medical prescriptions serve an analgesic and emetogenic purpose comparable to other prescribed drugs. (...) This vindicates the right for a physician to prescribe cannabis to qualified patients. For a patient to be considered qualified, they must be an adult that does not drive often, is not pregnant, and not at risk of schizophrenia or cardiovascular disease. If possible, cannabis should be eaten in an effort to avoid smoke irritation in the lungs and aerodigestive tract. In the end, the question is not whether cannabis use is efficable, but rather is the limitation of medical treatments to patients in need ethical? In light of the medical benefits, the banning of cannabis is simply immoral. Keywords: cannabis, banned substance, prescription, analgesic, emetogenic Note.

Crump et al.’s contribution to assessing whether decapods feel pain raises an important question: Is pain distributed unevenly across the order? The case for pain appears stronger in Pleocyemata than in Dendrobranchiata. Some studies report pain avoidance behaviors in Dendrobranchiata (Penaeidae) shrimp, but further studies are needed to determine whether the chemicals used are acting as analgesics to relieve pain, or as soporifics to reduce overall alertness. If the latter, the most farmed shrimp species may not require the same level (...) of protection as crabs, crayfish, and lobsters. (shrink)

Objective: Primary care, which is often the first level of contact for patients with various communicable diseases (CDs) and noncommunicable diseases (NCDs), might exhibit patterns of injectable drug utilization different from hospitals. We aimed to examine injection prescribing to adults with CD or NCD in primary care. -/- Methods: In this retrospective study, single-diagnosis injectable drug-containing prescription data from Family Medicine Information System comprising 32 provinces of Turkey were analysed. The prescriptions were grouped by diagnosis as “CD” (n=3848) and “NCD” (...) (n=9338). Injectable drug utilization patterns in these groups were analysed by demographics, diagnoses, and drug subgroups. -/- Results: Out of 13186 prescriptions, 70.8% were issued for NCDs. NCD prescriptions were mostly generated for women and elderly (p<0.05 for both). About 63.3% (n=2948) of injectable drugs in CD prescriptions were antibiotics and 12.6% were analgesics. Cefazolin (15.2%) was the most commonly prescribed antibiotic for acute pharyngitis and acute sinusitis, and benzathine benzylpenicillin (12.8%) was the top-choice for acute tonsillitis and rheumatic fever. In NCD prescriptions, 34.0% (n=4214) of injectable agents were analgesics and 16.9% were muscle relaxants. The most frequently encountered drug in NCD prescriptions was thiocolchicoside (16.3%), which was the top-choice in all seven common musculoskeletal diagnoses. -/- Conclusion: Muscle relaxants and analgesics were the most commonly prescribed injectable drugs for NCDs, musculoskeletal diseases in particular. Antibiotics were frequently encountered in CD prescriptions, mostly as broad-spectrum for lower respiratory tract infections (RTIs) and narrow-spectrum for upper RTIs. These findings may elucidate the issues to especially focus on regarding excessive use of injections. (shrink)

Placebos are often used by clinicians, usually deceptively and with little rationale or evidence of benefit, making their use ethically problematic. In contrast with their typical current use, a provocative line of research suggests that placebos can be intentionally exploited to extend analgesic therapeutic effects. Is it possible to extend the effects of drug treatments by interspersing placebos? We reviewed a database of placebo studies, searching for studies that indicate that placebos given after repeated administration of active treatments acquire (...) medication-like effects. We found a total of 22studies in both animals and humans hinting of evidence that placebos may work as a sort of dose extender of active painkillers. Wherever effective in relieving clinical pain, such placebo use would offer several advantages. First, extending the effects of a painkiller through the use of placebos may reduce total drug intake and side effects. Second, dose-extending placebos may decrease patient dependence. Third, using placebos along with active medication, for part of the course of treatment, should limit dose escalation and lower costs. Importantly, provided that nondisclosure is pre-authorized in the informed consent process and that robust evidence indicates therapeutic benefit comparable to that of standard full-dose therapeutic regimens, introducing dose-extending placebos into the clinical arsenal should be considered. This novel prospect of placebo use has the potential to change our general thinking about painkiller treatments, the typical regimens of painkiller applications, and the ways in which treatments are evaluated.

Health care providers are expected both to relieve pain and to provide anticipatory guidance regarding how much a procedure is going to hurt. Fulfilling those expectations is complicated by the cognitive modulation of pain perception. Warning people to expect pain or setting expectations for pain relief not only influences their subjective experience, but it also alters how nociceptive stimuli are processed throughout the sensory and discriminative pathways in the brain. In light of this, I reconsider the characterization of placebo analgesia (...) as pharmacologically inert and the use of it as deceptive. I show that placebo analgesia exploits the same physical mechanisms as proven analgesics and argue that it should be utilized to relieve pain. Additionally, I describe factors to help identify situations in which clinicians have the obligation to disclose the potential for pain coupled with ways of mitigating the risk of high-intensity pain by setting positive expectations.

Abstract: Retama raetam (RR) is a traditional medicinal plant belongs to fabaceae family which grows in North Africa and East Mediterranean region. Locally, RR is used in several diseases including diabetes mellitus and hypertension. Thus, this study aims to investigate certain behavioral and central effects of methanolic extract of RR seeds in experimental animals (male Albino adult mice of 20 – 35 gm). Three exploratory behavioral models are used in this study, open field, elevated plus maze and light-dark box models, (...) in addition, picrotoxin induced seizure model in mice. In elevated plus-maze test of anxiety, a dose of 25 mg/kg of RR induced a significant increase in number of open arms entries and time spent on open arms of the maze compared to the control. In light-dark model, time spent on light area and number of light-dark transitions are significantly increased after treatment with 25 mg/kg RR extract of seeds. Open field model also revealed a significant increase in general motor activity of the mouse after 25 mg/kg of RR. On the other hand, a dose of 50 mg/kg of RR significantly induced a profound central and peripheral analgesic responses. In summary, this study concludes that RR seeds have a profound anxiolytic-like effect and analgesic response with delay in latency time of seizure induced by picrotoxin in mice. (shrink)

Introduction: Liposomal bupivacaine (LB) is a long-acting analgesic that, due to its liposomal formulation, purportedly extends its analgesic effect up to 72 hours. However, the clinical efficacy of LB appears mixed. This systematic review seeks to evaluate the effectiveness of liposomal bupivacaine in improving postoperative outcomes compared to ropivacaine (ROPI), another commonly used long-acting analgesic. -/- Materials and Methods: Prospective and randomized controlled trials (RCTs) evaluating the efficacy of LB compared to ROPI were selected for review. Primary (...) outcomes included hospital length of stay (LOS) and postoperative opioid consumption measured in oral morphine equivalents (OME). Secondary outcomes included analgesic cost. -/- Results: 14 studies met the review criteria. We found that LB and ROPI are equivalent in managing postoperative pain. 8 of the 14 trials reported equal efficacy between LB and ROPI as determined by OME post-procedure and 10 of the 14 trials reported similar LOS after surgery. These findings remained consistent across multiple surgical procedures and multiple drug administrative modalities. -/- Conclusion: Our systematic review found that LB was not superior to ROPI in reducing postoperative OME use and hospital LOS. The only consistent finding was the significantly increased cost of LB compared to that of ROPI. Therefore, the use of LB over ROPI cannot be justified. (shrink)

My research is a result of accumulated provocation of obsolete and paralyzing education that has been frozen since the middle ages. We have to admit that before the pandemic, education was already in crisis. Governments have been ignoring to adopt any comprehensive plan to reform the educational systems till it has been unprecedently disrupted by COVID-19. I try through this paper to make a global call for governments to immediately start cooperating together for setting international qualifications framework that best suit (...) future competencies. This call should be prioritized on the world agenda. It would be more plausible for governments, UNESCO and other education stakeholders to seize the opportunity of the 2020 disruption of life cycle for the maximum benefit of humanity. For this to happen we need exceptional leaders with extraordinary vision to transform education instead of ensuring children can keep learning and that every single child returns to school after the pandemic. Another challenge to be expected is the reduction in education budgets being under pressure as governments shift spending towards the health and economic response to the pandemic. The impact of schools closing on a generation of children will be immense on the long term. We must act now to save the education and life chances of generations of youth. At this time of unprecedented crisis, the world must come together to protect education and put it at the very heart of the global recovery effort. Recovery, not as before but as convenient and sustainable with the perspective requirements. It is time to expose youth to real life experiences; we need our children to learn about finance from characters like Jef Bezos or Bill Gates or Mukesh Ambani; to learn about psychology from John Anderson, Eliot Aronson and Ahmed Ukasha; to know approaches of math and physics as Elon Musk and Steve Wozniak. We shouldn't settle for less when it comes to building minds and souls of our children. With all due respect to teachers and university professors, they are not the only best option for qualifying and training our youth for tomorrow's challenges. However, those entrepreneurs are not teachers or willing to be, education specialists and strategists are required to set the vision and the procedures required to pave the way for highly practical competencies framework. Analgesics are no longer feasible. (shrink)
