AbstractIntroduction:Laryngopharyngeal reflux is increasingly being implicated in several otolaryngological disorders.Aims:To study a potential correlation between pre-operative laryngopharyngeal reflux and wound healing and recovery after tonsillectomy, based on subjective and objective findings.Materials and methods:A prospective, blinded study was undertaken, including 60 patients scheduled for tonsillectomy, divided into two equal groups: a study group (group A) with pre-operative laryngopharyngeal reflux documented using ambulatory 24-hour pH monitoring; and a control group (group B) without laryngopharyngeal reflux.Results:Group A had significantly higher pain scores on the seventh and 14th post-operative days (p = 0.022 and p = 0.000, respectively) and took a significantly longer time to return to normal eating (p = 0.013), compared with group B. Group A also showed significantly slower healing on the seventh and 14th post-operative days, as estimated by assessing the grade of post-operative slough formation (p = 0.016 and p = 0.029, respectively). A significant correlation between the number of pharyngeal reflux episodes and the degree of post-operative slough was also found.Conclusions:Laryngopharyngeal reflux can significantly decrease wound healing following tonsillectomy. Therefore, pre-operative recognition and management of this condition is desirable in order to eliminate its negative post-operative effect.

Abstract Objective To investigate the impact of microecological preparation combined with modified low-carbon diet on the glucolipid metabolism and cardiovascular complication in obese patients. Methods From August 2017 to July 2020, 66 obese patients were recruited, and administrated with an modified low-carbon diet with (group A) or without (Group B) microecology preparation and a balanced diet in control group (group C) for 6 months. Meanwhile, 20 volunteers administrated with a balanced diet were recruited as the healthy control group (group D). Results After 6-month intervention, obese subjects in group A and B showed significant improvement of body and liver fat mass, reduction of serum lipid levels, intestinal barrier function markers, insulin resistance index (IRI), high blood pressure (HBP) and carotid intima thickness, as compared with subjects in group C. More importantly, subjects in group A had better improvement of vascular endothelial elasticity and intimal thickness than subjects in group B. However, these intervention had no effect on carotid atherosclerotic plaque. Conclusion Administration of microecological preparation combined with modified low-carbon diet had better improvement of intestinal barrier function, glucose and lipid metabolism, and cardiovascular complications than low-carbon diet in obese patients, but the effect of a simple low-carb diet on carotid atherosclerotic plaque need to be further addressed.

AIM: To investigate the protective effect of human umbilical cord mesenchymal stem cells (hUCMSCs) modified by the LIF gene on the retinal function of diabetic model rats and preliminarily explore the possible mechanism. METHODS: A stably transfected cell line of hUCMSCs overexpressing leukemia inhibitory factor (LIF) was constructed. Overexpression was verified by fluorescent quantitative polymerase chain reaction (qPCR). Forty-eight adult Sprague-Dawley rats were randomly divided into a normal control group (group A), streptozotocin-induced diabetic control group (group B), diabetic rats at 3mo injected with empty vector-transfected hUCMSCs (group C) or injected with LIF-hUCMSCs (group D). Four weeks after the intravitreal injection, analyses in all groups included retinal function using flash electroretinogram (F-ERG), retinal blood vessel examination of retinal flat mounts perfused with fluorescein isothiocyanate-dextran (FITC-dextran), and retinal structure examination of sections using hematoxylin and eosin staining. Expression levels of adiponectin (APN), high-sensitivity C-reactive protein (hs-CRP), and neurotrophin-4 (NT-4) in each group was detected using immunohistochemistry, PCR, Western blotting, and ELISA, respectively. RESULTS: A stable transgenic cell line of LIF-hUCMSCs was constructed. F-ERG and FITC-dextran examinations revealed no abnormalities of retinal structure and function in group A, severe damage of the retinal blood vessels and function in group B, and improved retinal structure and function in group C and especially group D. qPCR, ELISA, and Western blot analyses revealed progressively higher APN and NT-4 expression levels in groups B, C, and D than in group A. hs-CRP expression was significantly higher in group B than in groups A, C, and D, and was significantly higher in group C than in group D (P<0.05). CONCLUSION: LIF-hUCMSCs protect the retina of diabetic rats by upregulating APN and NT-4 expression and downregulating hs-CRP expression in the retina.

PURPOSE: To evaluate axonal regeneration after end-to-side nerve repair with fibrin glue in rats. METHODS: Forty-five Wistar rats were divided into three groups: group A (n=15), were not submitted to surgery (control group); group B (n=15) were submitted to fibular transection without repair; and group C (n=15), were submitted to fibular transection with end-to-side nerve anastomosis using fibrin glue, in the lateral surface of an intact tibial nerve. The three groups were submitted to walking track (30 and 90 days) and posterior morphometrical analysis (90 days). RESULTS: The functional tests demonstrated that there was no difference in the walking track during the study in group A (p>0.05). The group B had walking pattern impairment in the two tests (p>0.05). The group C had walking pattern impairment in the first test, with important recovery in the second test (p<0.05). The morphometrical assessment revealed significantly higher number of regenerated mielinates axons in group C, compared to group B (p<0.05). CONCLUSION: The end-to-side nerve repair with fibrin glue shows axonal recovery, demonstrated through functional and morphometrical ways in rats.

The effects of three dissolving agents on the accuracy of an electronic apex locator- (EAL-) integrated endodontic handpiece during retreatment procedures were evaluated. The true lengths (TLs) of 56 extracted incisor teeth were determined visually. Twenty teeth were filled with gutta-percha and a resin-based sealer (group A), 20 with gutta-percha and a zinc oxide/eugenol-based sealer (group B), and 16 roots were used as the control group (group C). All roots were prepared to TL. Guttasolv, Resosolv, and Endosolv E were used as the dissolving solutions. Two evaluations of the handpiece were performed: the apical accuracy during the auto reverse function (ARL) and the apex locator function (EL) alone. The ARL function of the handpiece gave acceptable results. There were significant differences between the EL mode measurements and the TL (P<0.05). In these comparisons, Tri Auto ZX EL mode measurements were significantly shorter than those of the TL.

Objective: To study the effect of liposomal curcumin combined with PDGFBB on tendon healing after tendon injury in rats and explore its mechanism. Methods Thirty-six rats were randomly divided into four groups: healthy control group (group A), liposomal curcumin group (group B), PDGF-BB group (group C) and combined application group (group D). The rats in each group were divided into groups according to the experimental group. At the 4th and 8th weeks after operation, the general morphology, histomorphology, biomechanics and other aspects of rat tendon were detected and statistically analyzed. Results: The degree of tendon adhesion in group B and D was significantly less than that in group A and C, and the difference was statistically significant. The biomechanical test showed that the tendons in group C and D had higher strength and could withstand greater stress than those in group A and B. Conclusion: Liposome curcumin combined with PDGF-BB can significantly reduce the degree of adhesion after tendon injury, increase the strength of tendon healing, and significantly promote tendon healing.

Objective: To establish the diagnostic utility of the platelet-lymphocyte ratio in pregnant women with preeclampsia. Methods: A case-control study was carried out at the Hospital Central “Dr. Urquinaona” Maracaibo, Venezuela. A total of 180 pregnant women were selected. Ninety preeclamptic women were included as the study group (group A) and a control group selected for their age and body mass index similar to the study group, which consisted of 90 healthy normotensive pregnant women (group B). The general characteristics, platelet-lymphocyte ratio values and diagnostic efficacy were determined. Results: Group A patients presented lower platelet and lymphocyte values compared to group B patients (p <0.001). However, no statistically significant differences were found in platelet-lymphocyte ratio between group A patients (115.2 ± 32.7) and group B patients (122.3 ± 23.8; p = 0, 0971). A cut-off value of the platelets-lymphocyte ratio of 117 presented a value below the curve of 0.57, the sensitivity of 47.8%, the specificity of 50.0%, the positive predictive value of 48.9%, and the negative predictive value of 52.2%, with a diagnostic accuracy of 48.9%. Conclusion: Platelet-lymphocyte ratio is not a useful tool in the diagnosis of preeclampsia, since patients with the syndrome present similar values to normotensive pregnant women.

Introduction: Non-pharmacological interventions are considered as successful adjuncts to manage pain. We are studying the comparative effects of listening to prayer recitation and music therapy intraoperatively as non-pharmacological interventions on postoperative pain and intraoperative haemodynamics. Materials and Methods: Seventy two muslim patients with acute appendicitis requiring open, emergency appendicectomies under general anaesthesia were recruited and randomised into three groups: Group A: patients who listened to prayer recitation, Group B: patients who listened to music, Group C: control group - patients who did not listen to any prayer or music. Intraoperative blood pressure, heart rate and postoperative pain scores were monitored. Results: The demographic data, pre- and post-headphones application haemodynamics were compared. There were significantly lower heart rates at 10, 20, 30, 40, 50, 60 minutes for Group A and at 50 and 60 minutes for Group B patients when compared to Group C. Significant reduction in postoperative pain scores were seen in Group A patients at 30 minutes and 8 hours as compared to Group C patients. No significant differences in pain scores were seen between Group B and C patients. No significant differences in additional analgesic requirements postoperatively were seen in all three groups. Conclusion: Listening to prayer recitation or music intraoperatively significantly lowered intraoperative heart rates, however only prayer recitation significantly reduced postoperative pain scores as compared to the control group.

The psychological strain of many psychiatric disorders arises from difficulties encountered in social interactions. Social withdrawal is often the first symptom of neuropsychiatric disorders. The authors explore the various options for training social cognition skills. Social cognition was assessed using the Movie for the Assessment of Social Cognition (MASC). After completion of mentalization-based therapy (MBT) training, MASC scores improved significantly in health care providers (p = .006, r = .57). Mentalizing (operationalized with reflective functioning [RF]) was assessed in the MBT group (Group A) and compared with RF in a control group (Group B). RF was significantly higher in Group A (RF = 4.35, SD = 1.19) than in Group B (RF = 3.43, SD = 1.70) (p = .0385; Cohen's d = 0.65). MBT might be a promising intervention in social cognition training. Mentalizing skills might be associated with attitude.
