The aim of this study was to investigate the therapeutic effect and possible mechanisms of tibial nerve stimulation (TNS) on visceral hypersensitivity in rats.
1) The effects of TNS with five sets of parameters on visceral sensitivity in normal rats were evaluated by the assessment of abdominal electromyogram (EMG) and abdominal withdrawal reflex (AWR). 2) The effects and mechanisms of TNS with a special set of parameters (14Hz, 330 μsec, and 40% motor threshold) were evaluated in acute visceral hypersensitivity rats induced by restraint stress and colonic hypersensitized rats induced by acetic acid during the neonatal stage assessed by the EMG, AWR, and the spectral analysis of heart rate variability derived from the electrocardiogram.
1) In normal rats, TNS did not show any effect on the visceromotor reflex. 2) In rats with restraint stress-induced hypersensitivity, TNS with the special set of parameters reduced AWR scores and EMG responses to rectal distention at a pressure of 20-60 mmHg (p < 0.05, vs. baseline for both AWR and EMG). Concurrently, TNS increased vagal activity and decreased sympathetic activity (p < 0.03 for both). 3) Similar effects were noted on the EMG (p < 0.05, vs. IACS-010759 cost baseline) and AWR (p < 0.05 vs. baseline) with acute and chronic TNS in rats with chronic colonic hypersensitivity and the effects were blocked by naloxone.
TNS with parameters of 14Hz, 330 μsec, and 40% motor threshold is effective in improving visceral hypersensitivity in rodent models of colonic hypersensitivity via the modulation of autonomic and opioid mechanisms.

In this paper, the application of waste medicine residue (large volume produced each year) as a precursor in producing a biochar that could adsorb Pb ion was reported. Biochar is a stable, aromatic, porous substance that is rich in carbon and prepared through pyrolysis of waste biomass under anaerobic conditions. In this study, medicine residue was used as raw material, and high-temperature sintering furnace was used to prepare medicine slag biochar at different temperatures of 200°C, 300°C, 400°C, 500°C, and 600°C. The resulting biochar was characterized by elemental analysis, Fourier transform infrared spectroscopy (FTIR), specific surface area analysis, field emission-scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and Raman spectroscopy (RS). Experimental results showed that with the increase in pyrolysis temperature, the biochar structure was destroyed. The yield decreased as the temperature gradually decreased from 81.69% to 33.90%. With the increase in temperature, the pH, the ash, and the fixed carbon gradually increased, whereas the number of surface functional groups decreased. The quasi second order kinetic equation can better fit the kinetic characteristics of adsorbing Pb ion by biochar. In general, this study provides a valuable method for recycling medicine residue.
Serious complications due to periorbital vascular occlusion can occur after facial injections, including skin necrosis, ophthalmoplegia, blepharoptosis, and visual loss. Visual loss after facial filler injection is particularly rare, but it is known to have a poor prognosis despite treatment.
This study aimed to describe the prognosis and various clinical features of periorbital vascular complications after facial injection of cosmetic filler or local anesthetic.
This single-center retrospective study included 10 consecutive patients who presented with occluded periorbital vessels after facial injection.
Nine patients were injected with cosmetic facial fillers seven with hyaluronic acid, one with collagen, and one with poly-Llactic acid. The other patient was injected with lidocaine mixed with epinephrine. Injection sites included the glabella (n=5), nasal dorsum (n=4), and temporal fossa (n=1). Presumed arteries affected included the central (n=2) or branch (n=3) retinal artery, ophthalmic artery (n=sion and injection materials. Visual prognosis was associated with the site of vascular occlusion and initial visual acuity. Other common complications, such as skin lesions, blepharoptosis, and limited extraocular movement, can fully resolve only with supportive treatments in most cases.
To determine independent associations between the use of medicines with anticholinergic or sedative effects and frailty with outcomes of length of stay (LOS), coronary artery procedure performed and 30-day deaths in octogenarians admitted for a myocardial infarction (MI).
We quantified patient exposure to medicines with anticholinergic or sedative effects using the drug burden index (DBI) and frailty using the hospital frailty risk score (HFRS). We used multivariable regression methods to determine the association between DBI and HFRS with outcomes of LOS, coronary artery procedures performed and 30-day deaths.
HFRS and not DBI score was significantly associated with receipt of coronary artery procedures (odds ratio [OR] 0.42; 95% CI 0.28-0.62 for high- versus low-risk groups) and 30-day deaths (OR 1.58; 95% CI 1.12-2.24 for high- versus low-risk groups).
Frailty risk is a more important predictor of outcomes than DBI score for octogenarians with an MI.

Anaemia is common in heart failure and associated with worse outcomes. We examined the effect of dapagliflozin on correction of anaemia in patients with heart failure (HF) and reduced ejection fraction in DAPA-HF. We also analysed the effect of dapagliflozin on outcomes, according to anaemia status at baseline.
Anaemia was defined at baseline as a haematocrit <39% in men and <36% in women. Resolution of anaemia was defined as two consecutive haematocrit measurements above these thresholds at any time during follow-up. The primary outcome was a composite of worsening HF (hospitalization or urgent visit requiring intravenous therapy) or cardiovascular death. Of the 4744 patients randomized in DAPA-HF, 4691 had a haematocrit available at baseline, of which 1032 were anaemic (22.0%). The rate of the primary outcome was higher in patients with anaemia (16.1 per 100 person-years) compared with those without (12.9 per 100 person-years). Anaemia was corrected in 62.2% of patients in the dapagliflozin group, compared with 41.
