Complex regional pain syndrome (CRPS) is characterized by pain accompanied by symptoms including skin changes, sensory, motor, trophic changes and autonomic dysfunction. Anticonvulsants and antidepressants are commonly prescribed for neuropathic pain conditions; however, evidence is sparse whether these drugs are effective in reducing CRPS-related pain. selleck products As such, Pubmed was searched for studies published from January 1990 through March 2020; 13 studies were included in this review. Overall, evidence is considered insufficient for use of gabapentinoids for CRPS-related pain. However, three randomized controlled trials (RCTs) did find gabapentin to result in significant improvement in pain whereas one RCT reported use of amitriptyline to be equally as effective as gabapentin. Multiple case reports discussing the efficacy of pregabalin in pediatric CRPS patients, with relatively short duration of disease and underlying psychiatric illness, have been reported, but these findings need to be validated with RCTs.
In multiple sclerosis (MS), up to 57% of white matter lesions are chronically active. These slowly expanding lesions (SELs) contribute to disability progression.
The aim of this study is to compare fingolimod and natalizumab effects on progressive linearly enlarging lesions (i.e. SELs), a putative biomarker of smouldering inflammation.
Relapsing-remitting MS patients starting fingolimod (
= 24) or natalizumab (
= 28) underwent 3T brain magnetic resonance imaging (MRI) at baseline, months 6, 12 and 24. SELs were identified among baseline-visible lesions showing ⩾ 12.5% of annual increase, calculated by linearly fitting the Jacobian of the nonlinear deformation field between timepoints obtained combining
- and
-weighted scans. SEL burden, magnetization transfer ratio (MTR) and
signal intensity were compared using linear models.
The prevalences of fingolimod (75%) and natalizumab patients (46%) with ⩾ 1 SEL were not significantly different (adjusted-
= 0.08). Fingolimod group had higher SEL number and volume (adjusted-
⩽ 0.047, not false discovery rate (FDR) survived). In both groups, SELs versus non-SELs showed lower MTR and
signal intensity (adjusted-
⩽ 0.01, FDR-survived). Longitudinally, non-SEL MTR increased in both treatment groups (adjusted-
⩽ 0.005, FDR-survived).
signal intensity decreased in SELs with both treatments (adjusted-
⩽ 0.049, FDR-survived in fingolimod group) and increased in natalizumab non-SELs (adjusted-
= 0.03, FDR-survived).
The effects of natalizumab and fingolimod on SEL occurrence seem modest, with natalizumab being slightly more effective. Both treatments may promote reparative mechanisms in stable or chronic inactive lesions.

We aimed to describe the MRI findings of patients after ECMO cannulation. Records of patients who underwent ECMO from September 2017 to June 2019 were reviewed. MRI studies were performed using multiplanar sequences consisting of T1-, T2-weighted, fluid attenuated inversion recovery (FLAIR), diffusion-weighted imaging (DWI), and susceptibility weighted images (SWI). link2 Of the 78 adult patients who underwent ECMO, 26 (33%) survived. link3 Of 26, eight patients (31%) had MRI studies, with a median age of 47 years (interquartile range [IQR] 25-57). The median ECMO support time was 8 days (IQR 4-25) and the median time from decannulation to MRI was 12 days (IQR 1-34). Five (63%) of eight patients had ischemic infarcts; 4 (50%) had cerebral microhemorrhage; 2 (25%) had intracranial hemorrhage; and 1 (13%) had thoracic cord ischemic infarct. There were no patients with normal MRI. All patients underwent transcranial Doppler (TCD). Four of 8 (50%) showed presence of microemboli with TCD; 3 of 4 (75%) had ischemic infarcts; and 1 of 4 (25%) had presence of multiple cerebral microhemorrhages on MRI. All ischemic infarcts had diffuse pattern of punctate to small lesions for ECMO survivors. The location of cerebral microhemorrhages included lobar (n = 4, 100%), deep (n = 2, 50%), and both (n = 2, 50%). Of the MRI studies, cerebrovascular related lesions were the most frequent, with punctate ischemic infarct being the most common type that may be associated with TCD microemboli. The results of the study suggest that subclinical cerebral lesions are commonly found in patients with ECMO support. Further research is needed to understand long-term effect of these cerebral lesions.Background A potential risk of neuropsychiatric adverse events (NPAEs) of oseltamivir has remained controversial by retrospective cohort studies. This nationwide population-based cohort study aimed to assess the risk of NPAEs in influenza patients undergoing oseltamivir treatment (users) compared with a propensity score-matched cohort of patients not receiving oseltamivir (non-users). Research design and methods Using the Korean National Health Service-Sample Cohort Database, patients diagnosed with incident influenza during 2003-2013 were divided into two cohorts oseltamivir users and non-users. We calculated adjusted hazard ratios (aHRs) for the 5-day treatment course with oseltamivir using Cox regression analysis. Results The incidence rate of NPAEs during 5-day oseltamivir treatment was 0.0029 and 0.0023 in oseltamivir users and non-users, respectively. The risk of NPAEs was different according to age, with an increased risk in patients aged 10-19 years (aHR 2.69, 95% CI 1.05-6.93) and a decreased risk in patients aged 0-9 years (aHR 0.46, 95% CI 0.24-0.88). The non-significant positive associations were observed in patients aged 20-64 years and those aged greater than 65 years. Conclusions Although the reason for the inverse association in children aged 0-9 years is unknown, oseltamivir could increase the risk of NPAEs for children or adolescents aged greater than 10 years.
Approximately 17% of young adults currently use tobacco, most commonly cigarettes and/or electronic cigarettes (e-cigarettes), followed by other products (i.e., cigarillos, pipe/hookah, smokeless tobacco). Cigarettes have been historically used to control weight. Little is known about use of non-cigarette products for weight control, particularly among non-college young adults. Tobacco use in the military is higher than civilians, and personnel have increased motivation for weight control due to military fitness standards. This population might be vulnerable to use tobacco for this purpose.
Exploring prevalence, as well as demographic and behavioral correlates, of using tobacco products for weight control, among a large, diverse sample of military young adults.
U.S. Air Force recruits (N = 24,543) completed a questionnaire about tobacco use. Among users of tobacco products, recruits reported if they had ever used that product to maintain their weight.
Smokeless tobacco was most commonly used for weted with ever using this product for weight control. Conclusions The belief that a tobacco product helps control one's weight might increase the prevalence, and frequency of use, of that product among military young adults. Tobacco cessation programs should assess for this motivation of use and provide education about tobacco harm and alternative strategies for weight maintenance.The aim of the current study was to develop the phytosomal gel of aloe vera extract for improved topical delivery. Aloe vera extract loaded phytosomal system was developed by fixing the amount of aloe vera extract and ethanol and by varying the concentration of lecithin (0.15-0.25% w/v) and speed of rotation (80-120 rpm). Different formulation batches were prepared as per the Design expert software. A 22 Factorial design was applied to optimize the formulation on the basis of vesicular size and entrapment efficiency. Developed formulations were evaluated for vesicular size, entrapment efficiency, PDI, zeta potential and in-vitro release. Further stability studies were also performed. For the optimized formulation (F09), vesicular size, entrapment efficiency and PDI were found as 123.1 ± 1.44 nm, 95.67 ± 0.27% and 0.98 ± 0.06. Zeta potential of -11.9 mV and drug release of 56.91 ± 4.1% obtained in 24 h. Drug release kinetics from the phytosomes follows Higuchi model. TEM micrograph confirms the uniform structure of phytosomes. Phytosomal gel of optimized phytosomal formulation (F09) was developed with 1% Carbopol 934 and physically characterized on the basis of pH, viscosity, homogeneity and drug content. Ex-vivo permeation study showed the better permeation and flux profile of phytosomal gel with the conventional aloe vera extract gel. Also, studies on phytosomal formulation and gel showed stability up-to 3 months. Thus overall, it can be concluded that the phytosomal gel is a good carrier for topical delivery of herbal extract such as aloe vera.Introduction Pembrolizumab is an immune checkpoint inhibitor with high specificity for binding to the programmed cell death 1 (PD-1) receptor. It has been approved by the FDA in patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy whose tumors express the programmed cell death ligand 1 (PD-L1).Areas covered Clinical studies of pembrolizumab in cervical cancer were analyzed and discussed. Data were obtained by searching for English peer-reviewed articles on PubMed, clinical trials registered on clincaltrials.gov and related abstracts on the ASCO meeting library. The aim was to review the status of pembrolizumab, the published and ongoing trials, and its safety and efficacy.Expert opinion Pembrolizumab may ultimately represent a treatment of choice for advanced cervical cancer with PD-L1 expression, both in metastatic and recurrent setting. However, it is essential to better identify and characterize patients that will benefit the most.
Inflammation as well as oxygen metabolite play important roles in renal injury during pathogenesis of rhabdomyolysis induced myoglobinuric acute renal failure (ARF). The aim of this study was to investigate the protective effects of donepezil on immune responses in rats with glycerol-induced ARF.
Sixty male rats were randomly divided into six groups, the rats were given normal saline (10 ml/kg, i.m.), glycerol (50%, 10 ml/kg, i.m.), glycerol plus dexamethasone (0.1 mg/kg, i.g.), and glycerol plus donepezil (1, 5 and 10 mg/kg, i.g.) respectively. After two weeks of glycerol injections, the kidney tissues and blood samples were harvested for future biochemical and pathology analysis. The levels of creatinine (Cr) and urea nitrogen (BUN) in plasma, the content of malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) activity, total nitric oxide synthase (TNOS), inducible nitric oxide synthase (iNOS), endothelial NO synthase (eNOS) were evaluated in renal tissues. In addition, interleukin-6 (IL-6), tumor necrosis factors-α (TNF-α) in renal tissues were also determined.
