BackgroundBlood glucose is tightly regulated in horses; however, since hypoglycaemia and hyperglycaemia are associated with poor prognosis, close monitoring is warranted. This study aimed at evaluating a continuous indwelling glucometer (CIG) by comparing performance with a point-of-care glucometer (POC).MethodsTen horses were equipped with CIG and an intravenous catheter. Interstitial glucose concentrations were determined by CIG every 5 min at rest, during insulin-induced hypoglycaemia and dextrose-induced hyperglycaemia, and compared with blood glucose determined by POC. Glucose concentrations were compared by two-way repeated measures analysis of variance and weighted kappa with Bland-Altman plots to determine agreement between assays.ResultsHorses tolerated CIG well; however, five devices had to be replaced. There were no statistically significant differences between assays at rest or during hyperglycaemia; however, during hypoglycaemia, glucose concentrations determined by CIG were significantly higher (P=0.01). The mean bias (95% limits of agreement) between assays ranged from −0.03 (−2.46 to 2.52) mmol/l (hyperglycaemia) to 0.97 (−1.23 to 3.16) mmol/l (hypoglycaemia). Assay agreement was ‘good’ with observed agreements of 87.04% (κ=0.67).Conclusions of the studyCIG has acceptable accuracy in horses as compared with POC but overestimates glucose concentrations during hypoglycaemia and requires frequent replacement, limiting its clinical application.

Abstract OBJECTIVE To determine the accuracy of 2 interstitial glucose-monitoring systems (GMSs) for use in horses compared with a point-of-care (POC) glucometer and standard laboratory enzymatic chemistry method (CHEM). ANIMALS 8 clinically normal adult horses. PROCEDURES One of each GMS device (Dexcom G6 and Freestyle Libre 14-day) was placed on each horse, and blood glucose concentration was measured via POC and CHEM at 33 time points and compared with simultaneous GMS readings. An oral glucose absorption test (OGAT) was performed on day 2, and glucose concentrations were measured and compared. RESULTS Glucose concentrations were significantly correlated with one another between all devices on days 1 to 5. Acceptable agreement was observed between Dexcom G6 and Freestyle Libre 14-day when compared with CHEM on days 1, 3, 4, and 5 with a combined mean bias of 10.45 mg/dL and 1.53 mg/dL, respectively. During dextrose-induced hyperglycemia on day 2, mean bias values for Dexcom G6 (10.49 mg/dL) and FreeStyle Libre 14-day (0.34 mg/dL) showed good agreement with CHEM. CLINICAL RELEVANCE Serial blood glucose measurements are used to diagnose or monitor a variety of conditions in equine medicine; advances in near-continuous interstitial glucose monitoring allow for minimally invasive glucose assessment, thereby reducing stress and discomfort to patients. Data from this study support the use of the Dexcom G6 and Freestyle Libre 14-day interstitial glucose-monitoring systems to estimate blood glucose concentrations in horses.

BackgroundPain is a common complication after laparoscopic surgery. This study aimed to examine the effect of an early mobilisation programme on postoperative pain intensity after laparoscopic surgery.MethodsA randomised controlled clinical trial was conducted on 80 patients who underwent laparoscopic surgery in Shahid Beheshti Hospital in Kashan, Iran. The patients were randomly allocated to intervention (n=40) and a control (n=40) group. In the intervention group, an early mobilisation programme was implemented in two rounds. The patient’s perceived pain was assessed using a Visual Analogue Scale 15 min before and 30 min after each round of early mobilisation. Data were analysed through the independent samples t, χ2 and Fisher’s exact tests and the repeated measures analysis.ResultsThe repeated measures analysis showed that the mean pain scores have been decreased over time (F=98.88, p<0.001). Considering the observed interaction between time and the intervention, the t test was used for pairwise comparisons and showed that the mean pain score was not significantly different between the two groups in 15 min before the first round of early mobilisation (p=0.95). However, the mean pain in the intervention group was significantly less than the control group in all subsequent measurements (p<0.05).ConclusionEarly mobilisation programmes such as the one implemented in the current study are easy and inexpensive and can be implemented safely for the reduction of pain after laparoscopic surgeries.

We studied six patients (5 paediatric, 1 neonate) treated with ECMO to quantify changes in inflammatory mediators (neutrophil elastase (NE), free radical activity (FR), interleukin 8 (IL8)) and total body water (TBW). Blood samples were taken before instigation of ECMO, 4, 12, 24 hours post-ECMO and daily for six days. FR activity was quantified using the oxidised IgG FI/UV ration. NE and IL8 levels were measured by ELISA. TBW was assessed by electrical bioimpedance. Statistical analysis was made using repeated measures analysis of variance and modified t-test where appropriate. Results are presented as mean ± standard error of the mean. FR activity increased 4 hours after instigation of ECMO (IgG FI/UV 32.1 ± 3.2 from 24.1 ± 3.0 p=0.005) and remained elevated. NE also increased by 4 hours (94.8 μg/L ± 8.9 to 678 μg/L ± 153.4, p=0.005) but returned to pre-ECMO values by day 6. IL8 levels rose after ECMO (from 98 pg/ml ± 39, to 24 pg/ml ± 117.4) although no statistical difference was noted over time due to the large variation between subjects (p=0.009). TBW (% pre-ECMO body weight) fell by 24 hours (from 118.6 ± 12.6 to 96.5 ± 8.2 p=0.0004). This study demonstrated that ECMO stimulates an ‘inflammatory’ response to extracorporeal perfusion (increased FR, NE) but despite this, results in a reduction in total body water. The complex relationship between the inflammatory response to prolonged extracorporeal perfusion and its effect on tissue oedema merits further investigation.

Objective To investigate differences in oxytocin (OXT) biodistribution between nonobese and obese parturients during labor. Study Design Patients with body mass index (BMI) of either ≥ 18 ≤ 24.9 kg/m2 (“nonobese”) or ≥ 30 kg/m2 (“obese”) undergoing elective induction of labor were included (N = 25 each). Blood samples were collected at baseline (T0), and 20 minutes after maximal OXT augmentation or adequate uterine contractions (T1) for OXT and oxytocinase assays. A mixed-model repeated-measures analysis of variance was used to test for group versus time interaction and analysis of covariance to detect a difference in OXT level at T1. Data presented as mean ± standard deviation or median (interquartile range), with p < 0.05 considered significant. Results The mean BMIs (kg/m2) were 22.1 ± 1.6 and 35.9 ± 5.1 in the nonobese and obese groups, respectively. No differences were observed in either the duration of OXT infusion, total dose of OXT, or plasma OXT (pg/mL) either at T0 or T1. However, plasma oxytocinase (ng/mL) was significantly lower at T0 (1.41 [0.67, 3.51] vs. 0.40 [0.29, 1.12]; p = 0.03) in the obese group. Conclusion We provide preliminary evidence that the disposition of OXT may not be different between obese and nonobese women during labor.

Because an operator has only about one chance out of three to place a composite increment within this clinically acceptable range, clinicians are advised to use an instrument (e.g., a periodontal probe with a 2-mm mark) to estimate the thickness of each increment of composite they place. SUMMARY Objective: To measure and compare the effect of operator experience in their ability to place composite in increments that are 2 mm thick. Methods and Materials: Fifteen volunteers from each class of freshmen, sophomores, juniors, and senior dental students and 15 clinical faculty (total number of volunteers = 75) were asked to restore a Class I preparation that was 5 mm in diameter and 8 mm deep from the cusp tips using three increments of composite that were each to be 2 mm thick. Once completed, the models were sectioned, and the thickness of each increment was measured. A repeated-measures analysis of variance (pre-set α=0.05) was used to compare the mean increment thickness with respect to operator experience level and increment sequence number. In addition, the proportion of operators placing clinically acceptable increments (between 1.75 and 2.25 mm thick), as well as the proportions from each group who placed increments that either were thinner or thicker than this range, was determined using nonparametric analyses. Results: Overall, there was an increasing trend for groups with a higher experience level to provide mean incremental thickness values close to 2 mm. However, the likelihood of placing an increment that was thicker or thinner than the manufacturer-recommended thickness was not significantly different. Regardless of the increment value, only about one-third of the increments placed fell within the desired range of 1.75 to 2.25 mm. Conclusions: Operator experience had no overwhelming significant influence on the ability to place increments of composite that were between 1.75 and 2.25 mm thick. An operator has only about one chance out of three to place a composite increment within this clinically acceptable range when using no external measurement system.

Introduction Traditional Chinese medicine offers several theories to explain the mechanism of acupuncture. One of these theories proposes that acupuncture points and meridians have unique electrical properties and their electrical skin impedance is lower than surrounding areas. The aim of this study was to evaluate the differences in electrical skin impedance between PC4 and the pericardium meridian compared with the surrounding areas. Methods Eighteen healthy subjects (10 women) were recruited to participate in the study. An impedance meter based on the four-electrode technique was designed specifically for the study. Twenty-five points were marked on the skin: one on the point PC4, four others on the pericardium meridian and 20 points around it. The electrical impedance of each point was measured with the four-electrode device. Results The mean electrical skin impedance at PC4 was significantly different from the 20 of the surrounding points but not significantly different from the four adjacent points. The mean skin impedance of the five points over the pericardium meridian was significantly different from that of parallel rows of points using repeated measures analysis of variance (p<0.001) Conclusion Within the possible limits of this measurement technique, skin impedance along the pericardium meridian is lower than surrounding areas, supporting the idea of different properties of the pericardium meridian compared with the control areas. Evidence on skin impedance at PC4 is inconclusive and further studies are needed.

Purpose. To evaluate the efficacy and safety of conbercept for patients with chronic central serous chorioretinopathy (CSC). Methods. A retrospective clinical study. Thirty-one patients (35 eyes) with chronic CSC were given intravitreal injections of conbercept and followed up for at least 6 months. Observed indicators included best-corrected visual acuity (BCVA), central macular thickness (CMT), and resolution of subretinal fluid (SRF). Serial changes in BCVA and CMT were analyzed by using repeated measures analysis of variance. Results. During the 6-month follow-up, the mean number of injections required and performed was 1.77 ± 0.60. The logMAR BCVA was 0.48 ± 0.26 at the baseline, 0.34 ± 0.26, 0.30 ± 0.26, 0.27 ± 0.26, 0.24 ± 0.26, and 0.23 ± 0.26 at 2-week and 1-, 2-, 3-, and 6-month follow-ups, respectively (F = 27.173, P<0.05). CMT was 313.74 ± 144.51 μm at the baseline and decreased to 263.49 ± 120.44 μm, 225.91 ± 91.98 μm, 195.77 ± 66.69 μm, 189.74 ± 65.41 μm, and 199.49 ± 81.50 μm at 2-week and 1-, 2-, 3-, and 6-month follow-ups, respectively (F = 18.093, P<0.05). Full resolution of SRF was achieved in 8 (22.9%) eyes at 1 month, 16 (45.7%) eyes at 2 months, 22 (62.9%) eyes at 3 months, and 27 (77.1%) eyes at 6 months after the initial treatment of anti-VEGF injection. No severe adverse event was noted relevant to the therapy. Conclusions. Intravitreal injection of conbercept may effectively reduce the CMT and improve the BCVA in chronic CSC in a short term of 6 months.

Dexmedetomidine (DEX) alone, or combined with butorphanol (BUT), may be administered by constant rate infusions (CRIs) in standing horses. This blinded, randomised, crossover study in six healthy adult horses aimed to determine the sedative and cardiopulmonary effects of DEX (dexmedetomidine (3.5 µg/kg+5 µg/kg/hour CRI) and DEX/BUT (dexmedetomidine (3.5 µg/kg+3.5 µg/kg/hour CRI) and butorphanol (20 µg/kg+24 µg/kg/hour CRI)). Head height above ground (HHAG), ataxia, responses to tactile/auditory stimuli and cardiopulmonary variables were recorded before, at 5/15/30/60/90 minutes and after CRIs terminated (15/30/60 minutes). Repeated measures analysis of variance with Tukey-Kramer test were used for cardiopulmonary values (mean±SD) and HHAG reduction (per cent), and Friedman’s and Dunn’s for non-parametric data (P<0.05). Maximum HHAG reductions of 54 per cent (DEX) and 58 per cent (DEX/BUT) occurred at 15 minutes, with ataxia for 15 minutes in both treatments. Responses to stimuli were reduced for 30 minutes in both treatments, and auditory up to 60 minutes in DEX. Cardiopulmonary effects typical of α2-agonists were observed, with no differences between treatments. At the doses and rates reported here, both regimens provided clinically sufficient sedation for only 30 minutes.
