Percutaneous electrical nerve stimulation (PENS) consists of applying an electric current of <1,000 Hz to different neuromuscular structures through acupuncture needles. Currently, there is ...controversy surrounding the effect of PENS on muscle strength in the scientific literature. The main objective was to assess the effect of PENS applied to the median and cubital nerves on the maximum handgrip strength (MHS) compared to sham stimulation, as well as to determine the safety of the intervention. A parallel, randomized, double‐blind controlled trial in a sample of 20 healthy subjects. Participants were randomly allocated in the experimental (n = 10) and control (n = 10) groups. A blinded researcher measured MHS. Measurements of MHS of the dominant hand were taken at four time points: preintervention, immediately postintervention, 24 hr after the intervention, and at a 10‐day follow‐up. A 10‐Hz percutaneous electrical current stimulation was employed. The control group also received the same puncture method but with no electric stimulation. Compared to baseline, the MHS decreased 10.4% (SEM = 3.2, p = .02) in the PENS group at 24 hr postintervention, with no differences observed between baseline and at 10 days postintervention. No changes in grip strength were observed at any time point in the sham group. To sum up, PENS decreased MHS at 24 hr postintervention, which does not persist 10 days after the stimulation. PENS can be considered a safe technique. Trials with larger sample sizes are required to corroborate the findings of this study. Clinical Trials Registration: NCT, NCT04662229, filed on March 12th of 2020.
Two new antibiotics, branimycins B (2) and C (3), were produced by fermentation of the abyssal actinobacterium Pseudonocardia carboxydivorans M-227, isolated from deep seawater of the Avilés ...submarine Canyon. Their structures were elucidated by HRMS and NMR analyses. These compounds exhibit antibacterial activities against a panel of Gram-positive bacteria, including Corynebacterium urealyticum, Clostridium perfringens, and Micrococcus luteus, and against the Gram-negative bacterium Neisseria meningitidis. Additionally, branimycin B displayed moderate antibacterial activity against other Gram-negative bacteria such as Bacteroides fragilis, Haemophilus influenzae, and Escherichia coli, and branimycin C against the Gram-positive Enterococcus faecalis and methicillin-sensitive and methicillin-resistant Staphylococcus aureus.
Abstract
Objective
To assess the effectiveness of cervical manual therapy (MT) on patients with temporomandibular disorders (TMDs) and to compare cervico-craniomandibular MT vs cervical MT.
Design
...Systematic review and meta-analysis (MA).
Methods
A search in PubMed, EMBASE, PEDro, and Google Scholar was conducted with an end date of February 2019. Two independent reviewers performed the data analysis, assessing the relevance of the randomized clinical trials regarding the studies’ objectives. The qualitative analysis was based on classifying the results into levels of evidence according to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE).
Results
Regarding cervical MT, MA included three studies and showed statistically significant differences in pain intensity reduction and an increase in masseter pressure pain thresholds (PPTs), with a large clinical effect. In addition, the results showed an increase in temporalis PPT, with a moderate clinical effect. MA included two studies on cervical MT vs cervico-craniomandibular MT interventions and showed statistically significant differences in pain intensity reduction and pain-free maximal mouth opening, with a large clinical effect.
Conclusions
Cervical MT treatment is more effective in decreasing pain intensity than placebo MT or minimal intervention, with moderate evidence. Cervico-craniomandibular interventions achieved greater short-term reductions in pain intensity and increased pain-free MMO over cervical intervention alone in TMD and headache, with low evidence.
Resistin is a cytokine related with inflammation and ischemic heart disease. Physical activity (PA) prevents chronic inflammation and ischemic heart disease. We studied the relationship of serum ...concentration of resistin with HDL cholesterol, a known biomarker of PA, and with different measures of PA, in a large sample of the general adult population in the Canary Islands.
Cross-sectional study of 6636 adults recruited randomly. We analyzed the correlation of resistin and HDL cholesterol with PA (as metabolic equivalent level MET), and fitted the results with linear and logistic regression models using adjustment for age, alcohol consumption and smoking.
Mean resistin level was higher in women (p<0.001), correlated inversely with age, HDL cholesterol (p<0.001) and alcohol consumption (p<0.001 in men), and correlated directly with smoking (p<0.001). Resistin correlated inversely with the duration of leisure time PA (p<0.001), leisure time MET (p<0.001) and moderate leisure time PA (p<0.001), with some differences between sexes. Men (OR = 0.78 0.61-0.99; p<0.05) and women (OR = 0.75 0.61-0.92; p<0.01) in the upper quintile of leisure time PA had a lower risk of elevated resistin. In contrast, a high degree of sedentarism was associated with an increased risk elevated resistin in women (OR = 1.24 1.04-1.47; p<0.05 and in men (OR = 1.40 1.01-1.82; p<0.05).
In our sample of the general population, resistin was inversely associated with measures and levels of PA and HDL cholesterol. The association of resistin with PA was stronger than the association of HDL cholesterol with PA, making resistin a potentially useful biomarker of PA.
Obesity is a negative chronic metabolic health condition that represents an additional risk for the development of multiple pathologies. Epidemiological studies have shown how maternal obesity or ...gestational diabetes mellitus during pregnancy constitute serious risk factors in relation to the appearance of cardiometabolic diseases in the offspring. Furthermore, epigenetic remodelling may help explain the molecular mechanisms that underlie these epidemiological findings. Thus, in this study we explored the DNA methylation landscape of children born to mothers with obesity and gestational diabetes during their first year of life.
We used Illumina Infinium MethylationEPIC BeadChip arrays to profile more than 770,000 genome-wide CpG sites in blood samples from a paediatric longitudinal cohort consisting of 26 children born to mothers who suffered from obesity or obesity with gestational diabetes mellitus during pregnancy and 13 healthy controls (measurements taken at 0, 6 and 12 month; total N = 90). We carried out cross-sectional and longitudinal analyses to derive DNA methylation alterations associated with developmental and pathology-related epigenomics.
We identified abundant DNA methylation changes during child development from birth to 6 months and, to a lesser extent, up to 12 months of age. Using cross-sectional analyses, we discovered DNA methylation biomarkers maintained across the first year of life that could discriminate children born to mothers who suffered from obesity or obesity with gestational diabetes. Importantly, enrichment analyses suggested that these alterations constitute epigenetic signatures that affect genes and pathways involved in the metabolism of fatty acids, postnatal developmental processes and mitochondrial bioenergetics, such as CPT1B, SLC38A4, SLC35F3 and FN3K. Finally, we observed evidence of an interaction between developmental DNA methylation changes and maternal metabolic condition alterations.
Our observations highlight the first six months of development as being the most crucial for epigenetic remodelling. Furthermore, our results support the existence of systemic intrauterine foetal programming linked to obesity and gestational diabetes that affects the childhood methylome beyond birth, which involves alterations related to metabolic pathways, and which may interact with ordinary postnatal development programmes.
Current scientific evidence has pointed out the relevance of hemostatic products for improving clinical outcomes in liver trauma, including increased survival rates and reductions in bleeding-related ...complications. The purpose of this study was to compare the use of the gelatin-thrombin flowable (Flowable) versus the standard technique of Packing in a new experimental liver injury model.
Twenty-four swine were prospectively randomized to receive either Flowable or standard packing technique. We used a novel severe liver injury model, in which the middle and left suprahepatic veins were selectively injured, causing an exsanguinating hemorrhage. The main outcome measure was the percentage of lost blood volume.
The median total percentage of total blood volume per animal lost, from injury to minute 120, was significantly lower in the Flowable group (15.2%; interquartile range: 10.7-46.7%) than in the Packing group (64.9%; Interquartile range: 53.4-73.0%) (Hodges-Lehmann median difference: 41.1%; 95% CI: 18.9-58.0%, p = 0.0034). The 24-hour survival rate was significantly higher in the Flowable group (87.0%) than in the Packing group (0.0%) (Hazard ratio (HR) 0.08; 95% confidence interval 0.102 to 0.27; p < 0.0001). Mean-arterial pressure was significantly lower at minute 60 and 120 in the Flowable group than in the packing group (p = 0.0258 and p = 0.0272, respectively). At minute 120, hematocrit was higher in the Flowable than in the packing group (Hodges-Lehmann median difference: 5.5%; 95%CI: 1.0 to11.0, p = 0.0267). Finally, the overall-surgical-procedure was significantly shorter with Flowable than with Packing (Hodges-Lehmann median difference: 39.5 s, 95% CI: 25.0 to 54.0 s, p = 0.0004).
The use of the Flowable was more effective in achieving hemostasis, reducing blood loss, and improving survival rates than standard packing in a severe porcine-liver bleeding model.
Cabazitaxel (CBZ), a novel tubulin-binding taxane, improves overall survival in metastatic castration-resistant prostate cancer (mCRPC) that progresses during or after docetaxel treatment. We have ...designed a phase II study to evaluate the efficacy and safety of CBZ as a weekly schedule for ‘unfit’ mCRPC patients after docetaxel failure.
In this single arm phase II study. CBZ was weekly administered in 1-hour infusion on days 1, 8, 15 and 22, every 5 weeks at 10 mg/m2 to eligible ‘unfit’ patients; oral prednisone (5 mg) was administered twice a day. Circulating tumour cells (CTCs) were also collected. New treatment scheme was considered effective if at least 65% of patients met a clinical benefit criteria based on prostate-specific antigen (PSA)-progression-free survival (PFS) values at week 12.
Seventy patients (median age: 73.9 years) were enrolled; overall, 71.4% had an Eastern Cooperative Oncology Group Performance Status (ECOG-PS) of 2; and 84%, 16% and 11% had bone, liver and lung metastases, respectively. Objective partial response or stable disease was achieved in 61% of patients, while PSA responses of ≥50% and ≥80% were observed in 34.8% and 10.6%, respectively. The median PSA-PFS was 4.8 months; and 68.6% of patients had no progression at week 12. The most frequent grade 3/4 toxicities were neutropenia (2.8%), leukopenia (5.7%) and thrombocytopaenia (9%); no cases of febrile neutropenia were reported. Early CTC response was significantly correlated with PSA-PFS.
CBZ/prednisone administered weekly to ‘unfit’ mCRPC patients appears to be as effective as classical standard 3-week scheme (TROPIC study) but with significantly lower toxicities and better tolerance. Early CTC response appears to be valuable as an early end-point of therapeutic efficacy.
•Weekly cabazitaxel instead of every 3 weeks has been tested.•Circulating tumour cells (CTCs) have been assessed.•‘Unfit’ patients could benefit with the proposed regimen.•Changes in CTCs could be useful in these cases as an early response marker.
One hundred ten patients with multiple myeloma (MM) failing to achieve at least near-complete remission (nCR) after a first autologous stem cell transplantation (ASCT) were scheduled to receive a ...second ASCT (85 patients) or a reduced-intensity-conditioning allograft (allo-RIC; 25 patients), depending on the human leukocyte antigen (HLA)–identical sibling donor availability. There was a higher increase in complete remission (CR) rate (40% vs 11%, P = .001) and a trend toward a longer progression-free survival (PFS; median, 31 months vs not reached, P = .08) in favor of allo-RIC. In contrast, it was associated with a trend toward a higher transplantation-related mortality (16% vs 5%, P = .07), a 66% chance of chronic graft-versus-host disease and no statistical difference in event-free survival and overall survival. Although the PFS plateau observed with allo-RIC is very encouraging, this procedure is associated with high morbidity and mortality, and therefore it should still be considered investigational and restricted to well-designed prospective clinical trials. This trial is registered at ClinicalTrials.gov ID number NCT00560053
This article presents a unique dataset, from a public building, of voltage data, acquired using a hybrid measurement solution that combines PythonTM for acquisition and GrafanaTM for results ...representation. This study aims to benefit communities, by demonstrating how to achieve more efficient energy management. The study outlines how to obtain a more realistic vision of the quality of the supply, that is oriented to the monitoring of the state of the network; this should allow for better understanding, which should in turn enable the optimization of the operation and maintenance of power systems. Our work focused on frequency and higher order statistical estimators which, combined with exploratory data analysis techniques, improved the characterization of the shape of the stress signal. These techniques and data, together with the acquisition and monitoring system, present a unique combination of low-cost measurement solutions, which have the underlying benefit of contributing to industrial benchmarking. Our study proposes an effective and versatile system, which can do acquisition, statistical analysis, database management and results representation in less than a second. The system offers a wide variety of graphs to present the results of the analysis, so that the user can observe them and identify, with relative ease, any anomalies in the supply which could damage the sensitive equipment of the correspondent installation. It is a system, therefore, that not only provides information about the power quality, but also significantly contributes to the safety and maintenance of the installation. This system can be practically realized, subject to the availability of internet access.
Knowledge of xanthogranuloma (XG) of the sellar region comes from short series or single cases. We performed a systematic review, using the PubMed, Web of Science, Embase, Scopus, eLibrary, and ...BIOSIS Preview databases, of all cases reported from 2000 to the present. We also describe one unreported patient treated in our institution. A search of the literature revealed that of 71 patients 50.7% were male and that mean age at diagnosis was 34.7 ± 19.2 years old. Median time from clinical onset until diagnosis was 7 (3-21) months. Hypopituitarism (70.4%), visual disorders (64.7%), headache (53.5%), and polyuria-polydipsia (28.2%) were the most common symptoms. On MRI, median tumor size was 20 (16-29) mm, while 71.8% were sellar/suprasellar and less frequently exclusively suprasellar (15.5%) or sellar (12.7%). On T1-weighted imaging, XG was hyperintense in 76.3% of patients, while it showed variable appearance on T2-weighted imaging. The tumor showed cystic features in 50.7%, gadolinium enhancement in 45.1%, and calcification in 22.5% of patients. All patients underwent surgery (77.4% transphenoidal approach and 18.3% craniotomy), with hypopituitarism (56.4%), diabetes insipidus (34.5%), and visual defects (7.3%) being the most common complications. Total/subtotal resection was achieved in 93.5%, while the tumor was partially removed in 6.6%. Median follow-up was 24 (6-55) months and no tumor recurrence or remnant growth was reported in 97.5% of cases. In conclusion, XG affects the younger population, manifested by hormonal deficit and mass effect symptoms. Surgery is safe and offers excellent outcomes, though hypopituitarism is frequent post-surgery. Tumor recurrence or remnant growth is rare and radiological surveillance is a good option for patients with remnant lesions.
