Abstract
BACKGROUND Laparoscopic right hemicolectomy (LRHC) is increasingly performed for the treatment of right colon disease. Nevertheless, standardization of the surgical technique regarding the performance of intracorporeal (IC) or extracorporeal (EC) anastomosis is lacking. The purpose of this study was to compare short-term postoperative outcomes in patients who had laparoscopic right colectomy either with IC or EC. METHODS This was a retrospective, non-randomized and multicenter study conducted from January 2005 to December 2015 on the CLIMHET study group cohort from five tertiary centers in France. Data were collected for all patients with LRHC to compare patient characteristics, intraoperative data and postoperative outcomes in terms of medical and surgical complications, duration of hospitalization and mortality. A multivariate analysis was performed to compare the results in the two groups. RESULTS Of the 597 patients undergoing LRHC, 150 had IC and 447 had EC. The incidence of medical complications (cardiac, vascular, and pulmonary complications) was lower in the IC group than in the EC group (13 vs 20%, p = 0.049). This difference remained significant in multivariate analysis after adjusting to field characteristics and patient histories (p = 0.009). Additionally, a shorter hospital stay (7 vs 8 days, p = 0.003) was observed in the IC group as compared to the EC group. This difference remained significant in favor of the IC group in multivariate analysis (p = 0.029). There was no difference between the groups as regards: surgical complications (p = 0.76), time of mobilization (p = 0.93), reintervention rate (p = 1) and 90-day mortality (p = 0.47). CONCLUSIONS Our results show that IC anastomosis in LRHC is associated with fewer medical complications and shorter hospital stays compared to EC anastomosis.

Nano-depletion of acrosome-damaged donkey sperm by using lectin peanut agglutinin (PNA)-magnetic nanoparticles. Theriogenology 2020; 151:103-111. [PMID: 32325322 DOI: 10.1016/j.theriogenology.2020.04.011] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 03/17/2020] [Accepted: 04/08/2020] [Indexed: 01/30/2023]
Abstract
Lectin is considered as a suitable biomarker for nano-depletion of acrosome-damaged sperm. The aim of this study was to synthetize magnetic nanoparticles (MNPs) coated by peanut (Arachis hypogaea) agglutinin lectin (PNA) and investigate its beneficial effect in improving of sperm characteristics. MNPs were obtained by co-precipitation method, functionalized with chitosan and coated by PNA at a concentration of 0.04 mg/mL. Semen was frozen either with glycerol-based or sucrose-based extenders. Frozen-thawed straws from five donkeys (three ejaculates per donkey) were incubated with lectin-MNPs (2 mg/mL), and then exposed to an external magnet enabling the non-bound sperm to be collected as nanopurified sperm. Sperm were evaluated post-thawing (control) and after nanopurification for motility, plasma membrane integrity, acrosome integrity, morphology, DNA fragmentation and concentration. The statistical analyses were extended to investigate the correlation between the initial quality of the frozen-thawed semen samples and the effect of nanopurification after thawing. The obtained MNPs were biocompatible to the sperm and significantly improved the progressive motility (P < 0.05) for the glycerol nanopurified group (43.08 ± 3.52%) in comparison to control (33.70 ± 2.64%). Acrosome-damaged sperm were reduced (P < 0.05) in both nanopurified groups (19.92 ± 2.69 for G and 21.57 ± 2.77 for S) in comparison to control (36.07 ± 3.82 for G and 35.35 ± 3.88 for S). There were no significant changes in sperm morphology and membrane integrity after nanopurification. The average sperm recovery after nanopurification was 80.1%. Sperm quality index was significantly higher (P < 0.001) in nanopurified groups regardless of the initial quality of the frozen thawed semen samples. However, in the high sperm quality group, nanopurification significantly improved the progressive motility and membrane integrity besides the increasing of acrosome-intact sperm. Sperm nanopurification using lectin-magnetic nanoparticles can be considered as a suitable method to reduce the proportion of acrosome-damaged sperm and to increase the quality of frozen thawed donkey semen.

Abstract
Bioemulsifiers are surface active compounds which could be potentially used in food processing, cosmetic sector and oil recovery. Sugarcane straw (SS), was used as the raw substrate for the production of bio-emulsifiers (BE) by Cutaneotrichosporon mucoides. Three different delignification strategies using dilute sodium hydroxide, sodium sulfite and ammonium hydroxide followed by enzymatic hydrolysis (Cellic CTec 2, 7.5% total solids, 15 FPU/g, 72 h) were studied. Enzyme hydrolysis of ammonium hydroxide pretreated SS showed a maximum of 62.19 ± 0.74 g/l total reducing sugars with 88.35% hydrolytic efficiency (HE) followed by sodium hydroxide (60.06 ± 0.33 g/l; 85.40% HE) and sodium sulfite pretreated SS (57.22 ± 0.52 g/l; 84.71% HE), respectively. The ultrastructure of SS (native and delignified) by fourier transform-infrared and near infrared spectroscopy, revealed notable structural differences. The fermentation of hydrolysates by C. mucoides into bioemulsifiers showing emulsification index (EI) of 54.33%, 48.66% and 32.66% from sodium sulfite, sodium hydroxide, and ammonium hydroxide pretreated SS, respectively.

Abstract
The aim of this study was to assess seasonal variations during different periods of the breeding season (spring and summer) on stallion sperm DNA fragmentation and in vivo fertility associated with cooled-stored semen samples. Ejaculates were collected from eleven stallions and assessed for sperm motility (assessed by computer-assisted sperm analysis) and plasma membrane integrity (evaluated under fluorescence microscopy). Sperm DNA fragmentation (evaluated by the Sperm Chromatin Dispersion test) was assessed in cooled-stored semen at 5 °C for up to 24 h. Artificial insemination was performed throughout the breeding season. Mares were inseminated with cooled-stored semen (up to 24 h) every other day until ovulation. Pregnancy rates per cycle were determined detecting the embryonic vesicle by ultrasonography fifteen days after ovulation. Values (mean ± SD) for progressive sperm motility were significantly higher (P < 0.05) in spring (53.57 ± 9.97%) in comparison to summer (41.37 ± 10.81%). No significant differences in plasma membrane integrity were found between seasons (P > 0.05). Sperm DNA fragmentation was significantly lower (P < 0.01) in spring in comparison to summer after 0h (4.81 ± 1.87% vs. 8.77 ± 5.78%), 6h (9.00 ± 3.19% vs. 18.73 ± 8.22%) and 24h (14.6 ± 4.13% vs. 30.14 ± 9.85%) of cooled-storage. Pregnancy rates per cycle were also significantly higher (P < 0.01) in spring (50%) in comparison to summer (37%). There was a moderate negative relationship between positive pregnancies and sperm with fragmented DNA (r = - 0.619; P < 0.001). Semen samples associated with moderate fertility levels (Pregnancy rate < 50%) showed a higher percentage of sperm with fragmented DNA compared to samples obtaining higher fertility levels. In conclusion, seasonal variations were found during the breeding season, obtaining lower sperm DNA fragmentation and higher pregnancy rates in spring. Additionally, samples with the highest proportion of sperm with fragmented DNA showed the lowest fertility levels throughout the breeding season.

Abstract
OBJECTIVES/BACKGROUND Rapid eye movement (REM) Sleep Behavior Disorder (RBD) in Parkinson's disease (PD) may be associated with a malignant phenotype. Despite its prognostic value, little is known about the time course of RBD in PD. In this study, we aimed to ascertain whether or not RBD is a stable feature in PD. In this study, we prospectively evaluated clinical and neurophysiological features of RBD, including REM Sleep Without Atonia (RSWA), in PD patients with RBD at baseline and after three years then assessed whether the changes in measures of RSWA parallel the progression of PD. PATIENTS/METHODS In sum, 22 (17M, mean age 64.0 ± 6.9 years) moderate-to-advanced PD patients (mean PD duration at baseline:7.6±4.8 years) with RBD, underwent a video-polysomnography (vPSG) recording and clinical and neuropsychological assessment at baseline and after three years. RESULTS At follow-up, the self-assessed frequency of RBD symptoms increased in six patients, decreased in six and remained stable in 10, while RSWA measures significantly increased in all subjects. At follow-up, patients showed worse H&Y stage (p = 0.02), higher dopaminergic doses (p = 0.05) and they performed significantly worse in phonetic and semantic fluency tests (p = 0.02; p = 0.04). Changes in RSWA correlated significantly with the severity in levodopa-induced dyskinesia (r = 0.61,p = 0.05) and motor fluctuation (r = 0.54,p = 0.03) scores, and with the worsening of executive functions (r = 0.78,p = 0.001) and visuo-spatial perception (r = -0.57,p = 0.04). CONCLUSION Despite the subjective improvement of RBD symptoms in one-fourth of PD patients, all RSWA measures increased significantly at follow-up, and their changes correlated with the clinical evolution of motor and non-motor symptoms. RBD is a long-lasting feature in PD and RSWA is a marker of the disease's progression.

Abstract
AIM Enhanced recovery programmes (ERPs) involve early postoperative oral feeding. The aim of this study was to test the hypothesis that intolerance to early feeding was associated with a complicated postoperative course. METHOD A retrospective cohort analysis of the prospective multicentre database developed by the Francophone Group for Enhanced Recovery after Surgery (GRACE) was undertaken. Seventy-one centres in Belgium, France and Switzerland participated in the study. All patients were encouraged to eat within 24 h after surgery. Patients were separated into two groups according to whether early feeding was well tolerated (WT) or poorly tolerated (PT). The primary outcome measure was overall postoperative complications. Secondary outcome measures were unplanned reoperation, early mobilization rate and duration of postoperative hospital stay. RESULTS Among the cohort of 3034 patients, early feeding was WT in 2614 patients (WT group) and PT in 420 patients (PT group). There were significantly more postoperative complications in the PT group than in the WT group (52.1% vs 17.0%, respectively; P = 0.001), namely more unplanned reoperations, less early mobilization and longer postoperative hospital stay. Multivariate analyses confirmed that PT early feeding was the main and dominant independent factor for postoperative complications [OR 4.47 (95% CI3.49-5.72); P < 0.001], more unplanned reoperations and longer hospital stay. CONCLUSIONS This study demonstrates a close relationship between intolerance to early feeding and a complicated postoperative course. Whenever this simple very early red flag is observed, discharge should not be planned until postoperative complications have been ruled out.

Abstract
AIM To analyse the prevalence of periapical lesions and their association with previous root canal treatment, root canal filling length and type of coronal restoration using in vivo cone-beam computed tomographic (CBCT) assessment. METHODOLOGY A global sample of 20 836 teeth, with a combined total of 27 046 roots, from 1160 patients, was analysed via CBCT assessment in eight health centres. Each tooth was evaluated by one out of five examiners after having performed a defined calibration procedure on the basis of 319 teeth. Intra- and inter-rater reliability tests were performed. Each tooth was classified according the tooth number, presence/absence of periapical lesions, presence/absence of previous root canal treatment, length of root canal filling (short, good or overfilling) and type of coronal restoration. The z-test for proportions was used to analyse differences between tooth subgroups, and an odds ratio was determined in order to analyse the association between treatment status and periapical lesions. A P < 0.05 was considered significant. RESULTS At a tooth level, the overall prevalence of periapical lesions in the sample was 10.4%. Maxillary teeth were associated with a significantly larger percentage of lesions (13.1%), whilst maxillary first molars had the greater proportion of lesions (21.2%). The prevalence of periapical lesions was significantly larger in root filled teeth (55.5%), short root canal fillings (72.7%) and in teeth restored with crowns (46.1%). At a root level, the mesiobuccal roots of both maxillary first molars had a tendency for a larger percentage of periapical lesions. CONCLUSION History of root canal treatment, root canal filling length and type of coronal restoration influenced the presence of periapical lesions. Molars were more commonly associated with periapical lesions on root filled teeth, particularly those with short root fillings and those with crowns.

Abstract
Medical tubings in plasticized polyvinylchloride (PVC) are widely used for the infusion of medications but are known in some cases to cause content-container interactions (drug sorption and plasticizer release). The aim of this study was to assess interactions between drugs and five alternative materials to a reference plasticized PVC intravenous (IV) infusion tubing: three were PVC coextruded with polyethylene (PE), polyurethane (PU) or a thermoplastic elastomer (Styrene-EthyleneButadiene-Styrene (SEBS)) and two were SEBS or thermoplastic olefin (TPO) monolayer tubings. Diazepam and insulin were chosen as respective reference of absorption and adsorption while paracetamol acted as a negative control. The concentration of each drug was quantified with liquid chromatography to evaluate a potential loss after a static contact condition and simulated infusion at 1 mL/h and 10 mL/h dynamic condition by an electric syringe pump. A characterization of each material's surface was performed by Fourier transform infrared spectroscopy in attenuated total reflection mode (ATR-FTIR) and by measurement of surface zeta potential. Plasticizer release was quantified by gas chromatography coupled with mass spectrometry (GC-MS). For all tubings except PVC/PU, no loss of paracetamol was observed in any condition. Diazepam sorption appeared to be less important with PVC/PE, PVC/SEBS, SEBS and TPO tubings than with PVC, but was more important when using PVC/PU tubings. PVC tubings induced the least loss of insulin amongst all the studied materials. Surface analysis by ATR-FTIR highlighted the presence of a plasticizer (that could be attributed to Tris (2-Ethylhexyl) Trimellitate (TOTM)) in the coextruded SEBS layer of PVC/SEBS, which could have influenced drug sorption, probably as a consequence of a migration from the PVC layer. Coextruded PVC/SEBS and PVC/PE presented the lowest zeta potential of all studied materials with respective values of -39 mV and -36 mV and were related to the highest sorption of insulin while PVC/PU with the highest zeta potential (about -9 mV) presented the highest absorption of diazepam. Coextruded layered materials appeared to have a lower plasticizer release than PVC alone. As a conclusion, PVC/PE and thermoplastic elastomers alone or coextruded with PVC could be interesting alternatives to PVC tubings with regards to sorption phenomena and plasticizer release.

Abstract
Many domestic donkey breeds are at risk of extinction, there is a critical urgency for genome resource banking. In the present study, we examined whether the use of Ficoll 70 added to the vitrification medium containing ethylene glycol (EG), dimethyl sulfoxide (DMSO) and sucrose improves the cryotolerance of donkey in vivo derived embryos. Day 7-8, grade 1-2 donkey embryos were measured and morphologically evaluated and then vitrified-warmed using the Cryotop technique. Before vitrification, embryos were randomly distributed into two groups: (i) VS1 (n = 14): vitrified using 15% EG + 15% DMSO + 0.5 M sucrose; and (ii) VS2 (n = 10): vitrified in the same medium supplemented also with 18% of Ficoll 70. After 24 h of warming, the embryos were measured and evaluated for their morphology, development and viability (Propidium Iodide-Hoechst 33342 dyes). Post-warming survival was numerically higher but not significantly different (P > 0.05) when embryos were vitrified in VS2 (70%) compared to VS1 (57.1%). Embryo rupture was only observed in the VS1 group (21.4%, 3/14). Higher embryo diameter was observed in all groups after 24 h culture (P < 0.05). No significant differences (P > 0.05) were observed among treatments in terms of percentages of cell death. These results demonstrate that the addition of Ficoll 70 to the vitrification medium is not a pre-requisite for successful vitrification of donkey embryos. However, its addition seems to enhance some of the post-warming embryo quality characteristics. Since no statistically significant evidence was found, further studies should be conducted in order to confirm our findings.

Abstract
Background The distress of patients suffering from a terminal illness can lead to a state of despair and requests for euthanasia and assisted suicide. It is a major challenge for palliative care workers. The Distress Thermometer (DT) is recommended by the National Comprehensive Cancer Network as a means of more easily assessing distress. It is available as a Self-assessment reported Distress Thermometer, but for a wider use in palliative care it should also be implemented in the form of a clinician-reported outcome (clinRO). Clinicians need to rate patient’s distress when the patient is not able to do so (subject that cannot be addressed, defensive patient…). The primary aim of the quantitative study was to assess the validity of the Clinician-Rated Distress Thermometer in palliative care. Method The assessments were performed by teams working in three palliative care centres. The primary endpoint was concordance between the patient and clinicians’ responses via Lin’s concordance coefficient. Eligible patients were aged 18 years or older, suffering from a severe disease in the palliative phase, and with a sufficient level of awareness to consent to participate in the study. A total of 51 patients were recruited, 55% were male, with a mean age of 65.8 years [39–90 years]. Results Three hundred sixty-four clinician-Rated Distress Thermometer and 467 Self-Reported Distress Thermometer were performed. Only 364 of the 467 Self-Reported Distress Thermometer were used for the study, as investigators did not systematically ask the patient to give an account of his distress. Concordance between patient and clinician responses: The Lin’s concordance coefficient with a threshold (alpha) of 5% was 0.46 [0.38; 0.54]. At the first assessment, it was 0.61 [0.44; 0.79]. The Cohen’s kappa coefficient was 0.52, with a concordance rate of 79.6%. The sensitivity was 82.9% [66.4–93.4] and the specificity 71.4% [41.9–91.6]. Conclusion The first assessment gave the best results in terms of concordance between Clinician-Rated DT and Self-Reported DT. In the next assessments, the Clinician-Rated DT were less consistent with the patients’ Self-Reported DT.

Abstract
PURPOSE The purpose of this study was to explore whether increasing the hip abduction angle would increase the incidence of avascular necrosis (AVN) in patients with late- detected developmental dysplasia of the hip (DDH) treated by closed reduction (CR) and spica cast immobilization. METHODS A total of 55 patients (59 hips) with late-detected DDH underwent MRI after CR. Hip abduction angle and hip joint distance were measured on postoperative MRI transverse sections. The acetabular index and centre-edge angle were measured on plain radiographs at the last follow-up. The presence of AVN according to Kalamchi and McEwen's classification was assessed. We retrospectively analyzed the associations among abduction angles, hip joint distances, radiographic parameters, AVN and final outcomes, exploring the relationship between hip joint abduction angle and AVN rate. RESULTS The mean age at the time of CR was 14.4 months SD 5.5 (6 to 28), and the mean follow-up was 26.2 months SD 8.1 (12.4 to 41.7). The mean hip abduction angle was 70.2° SD 7.2° (53° to 85°) on the dislocated side and 63.7° SD 8.8° (40° to 82°) on the normal side; the mean hip joint distance was 5.1 mm SD 1.9 (1.3 to 9.1) on the dislocated side and 2.2 mm SD 0.6 on the normal side (1.3 to 3.3). Eight of 59 hips (13.6%) developed AVN. Neither the amount of abduction nor hip joint distance increased the AVN rate (p = 0.97 and p = 0.65, respectively) or the dislocation rate (p = 0.38 and p = 0.14, respectively). CONCLUSION Abduction angle up to 70.2° following CR did not increase the AVN rate in children aged six to 28 months with late-detected DDH treated by CR. LEVEL OF EVIDENCE III.

Perceived barriers to and facilitators of physical activity in people with knee osteoarthritis: Development of the Evaluation of the Perception of Physical Activity questionnaire. Ann Phys Rehabil Med 2019; 63:202-208.

Abstract
BACKGROUND The physical activity (PA) level of individuals with knee osteoarthritis is lower than in the general population. International recommendations recommend a non-pharmacological intervention including a self-management education program, weight loss and an adapted exercise program. However, we have no scale assessing the perceived barriers to and facilitators of PA in this population. OBJECTIVE We constructed and validated a self-administered questionnaire assessing perceived barriers to and facilitators of regular practice of PA in people with knee osteoarthritis. METHODS Semi-structured interviews identified 24 barriers and facilitators. We developed a 24-item questionnaire, Evaluation of the Perception of Physical Activity (EPPA) that was completed by 548 individuals with knee osteoarthritis, to assess acceptability, construct validity, internal consistency and convergent validity. Participants also completed the Knee Osteoarthritis Fears and Beliefs Questionnaire (KOFBeQ), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and International Physical Activity Questionnaire (IPAQ). Reliability and sensitivity to change were evaluated in a second group of 168 people with knee osteoarthritis at a 3-week spa therapy resort. RESULTS Factorial analysis identified 17 items grouped into 4 subscales (Barriers, Facilitators, Motivation and Beliefs). The internal consistency was good for Barriers, Facilitators and Motivation subscales (Cronbach α>0.70) and intermediate for the Beliefs subscale (Cronbach α=0.64). The EPPA subscale scores were significantly correlated with KOFBeQ and WOMAC scores but not associated with IPAQ physical activity level. Reliability was good for all subscales, with intraclass correlation coefficients>0.60. A sensitivity to change was found for only the Beliefs subscale, with a moderate effect size. CONCLUSIONS The EPPA questionnaire has good psychometric properties and can help guide the management of knee osteoarthritis. It can be used in research for evaluating the perception of physical activity.

Abstract
Many instruments exist for measuring grip strength. The Jamar hydraulic hand dynamometer is currently the gold standard. The Labin is a prototype electronic dynamometer that can also measure maximum grip strength. The main objective was to compare the Labin dynamometer with the gold standard instrument, the Jamar, in a healthy population, and secondarily to compare discomfort during use. A single-center exploratory study was conducted. The subjects enrolled had to be aged between 20 and 60, be volunteers and give consent. The required number of subjects was 30. The subjects were positioned according to American Society of Hand Therapists recommendations. Maximum grip force was measured in kilograms using the mean of three successive trials. The first dynamometer used was chosen randomly. The handle's discomfort during use was rated on a simple verbal scale from 0 to 10. Thirty-four subjects were included. The concordance coefficient for peak torque between the Labin and Jamar dynamometers was 0.90 for the dominant hand and 0.83 for the non-dominant hand. The intraclass correlation coefficient for peak torque with the Labin was 0.81 [0.69; 0.89] for the dominant hand and 0.86 [0.76; 0.92] for the non-dominant hand. In our study, we have shown that the Labin prototype has acceptable validity and reproducibility. The Labin will need to be tested in pathological conditions next.

Abstract
Abstract
Editor’s Perspective
What We Already Know about This Topic
What This Article Tells Us That Is New
Background
Central pain sensitization is often refractory to drug treatment. Dextromethorphan, an N-methyl-d-aspartate receptor antagonist, is antihyperalgesic in preclinical pain models. The hypothesis is that dextromethorphan is also antihyperalgesic in humans.
Methods
This randomized, double-blind, placebo-controlled, crossover study explores the antihyperalgesic effect of single and repeated 30-mg dose of oral dextromethorphan in 20 volunteers, using the freeze-injury pain model. This model leads to development of primary and secondary hyperalgesia, which develops away from the site of injury and is associated with central sensitization and activation of N-methyl-d-aspartate receptor in the spinal cord. The primary outcome was antihyperalgesia calculated with the area under the curve of the percentage change in mechanical pain threshold (electronic von Frey) on the area of secondary hyperalgesia. The secondary outcomes were mechanical pain threshold on the area of primary hyperalgesia and cognitive (reaction time) effect.
Results
Single 30-mg results are reported. Antihyperalgesia (% · min) is significantly higher on the area of secondary hyperalgesia with dextromethorphan than placebo (median [interquartile range]: 3,029 [746; 6,195] vs. 710 [–3,248; 4,439], P = 0.009, Hedge’s g = 0.8, 95% CI [0.1; 1.4]). On primary hyperalgesia area, mechanical pain threshold 2 h after drug intake is significantly higher with dextromethorphan (P = 0.011, Hedge’s g = 0.63, 95% CI [0.01; 1.25]). No difference in antinociception is observed after thermal painful stimuli on healthy skin between groups. Reaction time (ms) is shorter with placebo than with dextromethorphan (median [interquartile range]: 21.6 [–37.4; 0.1] vs. –1.2 [–24.3; 15.4], P = 0.015, Hedge’s g = 0.75, 95% CI [0.12; 1.39]). Nonserious adverse events occurrence (15%, 3 of 20 volunteers) was similar in both groups.
Conclusions
This study shows that low-dose (30-mg) dextromethorphan is antihyperalgesic in humans on the areas of primary and secondary hyperalgesia and reverses peripheral and central neuronal sensitization. Because dextromethorphan had no intrinsic antinociceptive effect in acute pain on healthy skin, N-methyl-d-aspartate receptor may need to be sensitized by pain for dextromethorphan to be effective.
