81 ± 1.47 vs O + B 1.87 ± 1.40, P = 0.688). No differences were noted in speed of onset or duration of analgesia. Although more patients subjectively preferred the O + B treatment, the difference was not statistically significant. No differences were noted in secondary outcome measures, with the exception of global impression of change having higher scores in O compared with O + B. CONCLUSIONS Acutely removing bupivacaine from a chronic intrathecal infusion of opioids and bupivacaine in patients with chronic noncancer pain did not adversely affect PCIA effectiveness, nor did it affect speed of onset or duration of effect. These findings are divergent from those in acute pain and may have to do with study conditions and pain phenotypes. buy NaB inhibitor © The Author(s) 2020.

It describes how a personalized nutrition practice approach supported by evidence-based pathophysiological reasoning could direct additional research, which could then transform practice and support food industry developments. Current use of the term "personalized nutrition" is reviewed and a definition is provided. Also explored are current approaches to personalized nutrition practice and evidence-based practice in clinical nutrition. Patient-centered practice, which involves individuals in their healthcare decisions, is currently being provided under the name "personalized." An evidence-based personalized practice approach should include the use of robust, standardized, and validated tools that gather a patient's signs and symptoms, health history, family history, genetics, environment, lifestyle, social life, diet, behavior and other factors that have an impact o participatory. Developing pathophysiological mechanistic understanding also provides new opportunities for stakeholders, including the food industry, researchers, healthcare practitioners, and consumers. © The Author(s) 2020.

Only one example, in canine muscle, has been published previously. This study evaluated human muscle biopsies for foci of contracted sarcomeres. SETTING The Departments of Rehabilitation Sciences and Physiotherapy at Ghent University, Ghent, Belgium. SUBJECTS Biopsies from 28 women with or without trapezius myalgia were evaluated, 14 in each group. METHODS Muscle biopsies were obtained from regions of taut bands in the trapezius muscle and processed for light and electron microscopy and for histochemical analysis. link2 Examination of the biopsies was blinded as to group. RESULTS A small number of foci of segmentally contracted sarcomeres were identified. One fusiform segmental locus involved the entire muscle fiber in tissue from a myalgic subject. Several transition zones from normal to contracted sarcomeres were found in both myalgic and nonmyalgic subjects. The distance between Z-lines in contracted sarcomeres was about 25-45% of the same distance in normal sarcomeres. Z-lines were disrupted and smeared in the contracted sarcomeres. CONCLUSIONS A small number of foci of segmentally contracted sarcomeres were found in relaxed trapezius muscle in human subjects, a confirmation of the only other example of spontaneous segmental contraction of sarcomeres (in a canine muscle specimen), consistent with the hypothesis of trigger point formation and with the presence of trigger point end plate noise. © 2020 American Academy of Pain Medicine.

The goal of this study was to explore the functioning of the nociceptive afferent pathways by examining LEPs in patients with chronic whiplash-associated disorders (cWAD), patients with chronic fatigue syndrome (CFS), and healthy controls (HCs). DESIGN Case-control study. SETTING A single medical center in Belgium. SUBJECTS The LEPs of 21 patients with cWAD, 19 patients with CFS, and 18 HCs were analyzed in this study. METHODS All participants received brief nociceptive CO2 laser stimuli applied to the dorsum of the left hand and left foot while brain activity was recorded with a 32-channel electroencephalogram (EEG). LEP signals and transient power modulations were compared between patient groups and HCs. RESULTS No between-group differences were found for stimulus intensity, which was supraliminal for Aδ fibers. The amplitudes and latencies of LEP wave components N1, N2, and P2 in patients with cWAD and CFS were statistically similar to those of HCs. link3 There were no significant differences between the time-frequency maps of EEG oscillation amplitude between HCs and both patient populations. CONCLUSIONS EEG responses of heat-sensitive Aδ fibers in patients with cWAD and CFS revealed no significant differences from the responses of HCs. These findings thus do not support a state of generalized central nervous system hyperexcitability in those patients. © The Author(s) 2020.

DESIGN Retrospective cohort study. SETTING Multisite federally qualified health center using an interdisciplinary committee to provide patient-specific recommendations to prescribers with patients using prescription opioids and other controlled substances. SUBJECTS Patients prescribed long-term opioids. METHODS We identified and characterized committee recommendations to prescribers between January 1, 2013, and December 31, 2016. We manually reviewed electronic medical records to determine if recommendations were accepted at eight months. The primary outcome was the overall acceptance rate of recommendations. Secondary outcomes were the acceptance of recommendations to reduce opioid doses and change in opioid dose from baseline. RESULTS The committee made 337 recommendations for 94 patients. Of those, 169 recommendations (50.1%) were accepted within eight months.

The latter might rely on connections between olfactory and emotional structures, suggesting possible effects of a similar approach in pain patients. Based on neuroanatomy, there are several interfaces between the "pain network" and olfactory system, such as the limbic system, hypothalamus, and mediodorsal thalamus. We aimed to investigate whether structured exposure to odors may impact perceived pain in patients with chronic low back pain. DESIGN Randomized controlled parallel-group design. Subjects were tested on two occasions, at baseline and after four weeks. SETTING Ambulatory. SUBJECTS Forty-two patients with chronic low back pain. METHODS For all patients, olfactory function (using the "Sniffin'Sticks" test kit), detection, and pain thresholds for cutaneous electrical stimuli (applied to the forearm) were tested at baseline and after four weeks. Twenty-eight patients exposed themselves to four odors (rose, vanilla, chocolate, peach) every two hours over a period of four weeks (training group). Control patients (N = 14) underwent no such "olfactory training" (nontraining group). RESULTS Pain thresholds were significantly increased in patients who performed olfactory training compared with patients who did not train with odors. Detection thresholds and olfactory function remained unchanged. CONCLUSIONS The present results indicate that regular exposure to odors increases pain thresholds in patients with chronic back pain and could be useful for general pain control in these patients. Furthermore, olfactory training in chronic pain patients might help to reduce chronification of pain by desensitization. © The Author(s) 2020.

Different hosts or host tissues provide different cellular environments, especially different antiviral and RNA modification activities that can alter RNA modification signatures observed in the viral RNA genome. The zinc finger antiviral protein (ZAP) binds specifically to CpG dinucleotides and recruits other proteins to degrade a variety of viral RNA genomes. Many mammalian RNA viruses have evolved CpG deficiency. Increasing CpG dinucleotides in these low-CpG viral genomes in the presence of ZAP consistently leads to decreased viral replication and virulence. Because ZAP exhibits tissue-specific expression, viruses infecting different tissues are expected to have different CpG signatures, suggesting a means to identify viral tissue-switching events. I show that SARS-CoV-2 has the most extreme CpG deficiency in all known Betacoronavirus genomes. This suggests that SARS-CoV-2 may have evolved in a new host (or new host tissue) with high ZAP expression. A survey of CpG deficiency in viral genomes identified a virulent canine coronavirus (Alphacoronavirus) as possessing the most extreme CpG deficiency, comparable to that observed in SARS-CoV-2. This suggests that the canine tissue infected by the canine coronavirus may provide a cellular environment strongly selecting against CpG. Thus, viral surveys focused on decreasing CpG in viral RNA genomes may provide important clues about the selective environments and viral defenses in the original hosts. © The Author(s) 2020.

The measurement method using photoacoustic detection in the present study can be applied to a wide variety of samples and measurement conditions.Differential scanning calorimetry (DSC), thermogravimetry (TG) and in situ XRD were used to study dehydration and consequent decomposition reactions of mixed calcium oxalate hydrates. As the complex dehydration kinetics exhibited certain trends with respect to the applied heating rate, the modified multivariate kinetic analysis approach (based on averaged curve-by-curve optimizations) was employed to obtain a full kinetic description of the data. The Šesták-Berggren equation was used to model the two consequent dehydration reactions. Good agreement was found between the kinetic parameters calculated from the DSC and TG data - approximate values of activation energies were 68 and 81 kJ mol-1 for the trihydrate → monohydrate and monohydrate → anhydride transformations, respectively. A procedural methodology was developed to predict both dehydration kinetics and hydrate content ratios. For the calcium oxalate decomposition the TG technique provided very precise single-step prediction with an activation energy of 180 kJ mol-1.
