Object The object of this study was to examine the efficacy of preoperative teriparatide treatment for increasing the insertional torque of pedicle screws during fusion surgery in postmenopausal women with osteoporosis. Methods Fusion surgery for the thoracic and/or lumbar spine was performed in 29 postmenopausal women with osteoporosis aged 65–82 years (mean 72.2 years). The patients were divided into 2 groups based on whether they were treated with teriparatide (n = 13) or not (n = 16) before the surgery. In the teriparatide-treated group, patients received preoperative teriparatide therapy as either a daily (20 μg/day, n = 7) or a weekly (56.5 μg/week, n = 6) injection for a mean of 61.4 days and a minimum of 31 days. During surgery, the insertional torque was measured in 212 screws inserted from T-7 to L-5 and compared between the 2 groups. The correlation between the insertional torque and the duration of preoperative teriparatide treatment was also investigated. Results The mean insertional torque value in the teriparatide group was 1.28 ± 0.42 Nm, which was significantly higher than in the control group (1.08 ± 0.52 Nm, p < 0.01). There was no significant difference between the daily and the weekly teriparatide groups with respect to mean insertional torque value (1.34 ± 0.50 Nm and 1.18 ± 0.43 Nm, respectively, p = 0.07). There was negligible correlation between insertional torque and duration of preoperative teriparatide treatment (r2 = 0.05, p < 0.01). Conclusions Teriparatide injections beginning at least 1 month prior to surgery were effective in increasing the insertional torque of pedicle screws during surgery in patients with postmenopausal osteoporosis. Preoperative teriparatide treatment might be an option for maximizing the purchase of the pedicle screws to the bone at the time of fusion surgery.

Background<br />Reducing postoperative pain can improve patient satisfaction and hospital cost. Intravenous magnesium sulfate is one of the proposed drugs for preemptive analgesia. The study aimed to evaluate the effect of magnesium sulfate on postoperative pain in patients undergoing lumbar fusion surgery.<br /><br />Methods<br />A double-blind randomized clinical trial was conducted on candidates for vertebral fusion surgery with American Society of Anesthesiologists (ASA) class I-II. One hundred and two patients were randomized into the magnesium sulfate group and control group. The magnesium sulfate group received magnesium sulfate at a dose of 50mg/kg in 20 mL volume and infused during 15-30 minutes pre-operation, while the control group received 20 mL normal saline. The severity of the pain was assessed by the Visual Analogue Scale (VAS) at 2, 4, 6, 12 and 24 hours after patients entering the post-anesthetic care unit. After the operation, the patients’ relaxation rate was assessed based on Ramsay sedation score (RSS).<br /><br />Results<br />There was no significant difference at 2, 4, 6, 12 and 24 hours post-operation between the two groups in the mean severity of pain (p&gt;0.05). There was no significant difference at 2, 4, 6, 12 and 24 hours post-operation between the two groups in the mean of pethidine consumption. There was no significant difference in the relaxation of the patients according to the RSS criteria in the magnesium sulfate and control groups (p=0.162). <br /><br />Conclusion<br />Pre-operative administration of magnesium sulfate does not affect reduction in postoperative pain and opioid consumption of patients undergoing lumbar fusion surgery.

Treatment with linearly polarized light (LPL) is a widely used and recognized therapeutic method in human medicine for healing wounds, ulcers and a variety of other dermatological problems. Polarized light mobilizes the inadequately functioning defence mechanisms of the human body. The aim of the present experiment was to investigate the effect of LPL treatment on the udder of milking cows. Before the start of treatment, there was no significant difference between cows to be treated with LPL and the control cows in mean somatic cell counts (SCC) of milk samples taken separately by udder quarter and in the mean milk yield. The LPL treatment lasted for 20 min and was performed twice a day over a period of one month. Before treatment, the mean SCC of milk was 3.47 × 105 ± 910 in the group to be treated and 4.07 × 105 ± 920 in the control group. In a six-week period immediately after treatment, the mean SCC of the treated and the control group was 1.32 × 105 ± 825 and 2.63 × 105 ± 825, indicating a significant difference in favour of the treated group. Before the LPL treatment, the milk yield of cows in the group to be treated was 25.77 ± 1.2 kg/ day, while that of the control cows was 27.30 ± 1.4 kg/day. In a six-week period after treatment, the milk yield of cows in the treated and control groups was 28.83 ± 1.5 kg/day and 25.48 ± 1.4 kg/day, respectively. There is a significant difference between these values in favour of the treated group. The results show that a regular LPL treatment of the udder of cows can significantly reduce the SCC of milk and significantly increase the milk yield. The treatment can be applied during lactation without interfering with the milking regime.

IntroductionThe present study aimed to investigate the potential effects of rivaroxaban, an oral anticoagulant that inhibits the effects of factor Xa on intact intervertebral disc tissue cells and the extracellular matrix (ECM).Material and methodsRivaroxaban was applied to primary human cell cultures prepared from tissues of the intervertebral disc. Comparative molecular analyses were performed on non-drug-treated control group samples. Descriptive statistics were presented as the mean ± standard deviation. An analysis of variance (ANOVA) test was performed to determine whether there were significant differences in the mean across the groups. When differences across groups were observed, Tukey’s honestly significant difference (HSD) post-hoc test was used for multiple pairwise comparisons. The significance of the obtained data was determined statistically. The alpha (P) significance value was < 0.05.ResultsThe cells in the control group and in the rivaroxaban-treated group were viable, healthy, and proliferated (P < 0.05). However, the expressions of the chondroadherin gene (CHAD), cartilage oligo matrix protein (COMP), matrix metallo proteinase (MMP)-13, and MMP-19 genes were changed (P < 0.05).ConclusionsAlthough rivaroxaban does not suppress cell proliferation due to morphological, biological, and biochemical changes in the intervertebral disc tissue, it may change the expression of genes that are related to ECM maintenance.

This study was designed to assess the relative importance of Cl− and HCO3− secretion to mucociliary transport rate (MCT) in ex vivo porcine tracheas. MCT was measured in one group of tissues that was exposed to adventitial HCO3−-free solution while a parallel group was exposed to adventitial HCO3−-replete solution. After measurement of baseline MCT rates, acetylcholine (ACh) was added to stimulate submucosal gland mucous liquid secretion, and MCT rates were again measured. Before ACh addition, the mean MCT was higher in the HCO3−-free group (4.2 ± 0.9 mm/min) than in the HCO3−-replete group (2.3 ± 0.3 mm/min), but this difference was not statistically significant. ACh addition significantly increased MCT in both groups, but ACh-stimulated MCT was significantly lower in the HCO3−-free group (11.0 ± 1.5 mm/min) than in the HCO3−-replete group (17.0 ± 2.0 mm/min). A second series of experiments examined the effect on MCT of blocking Cl− secretion with 100 μM bumetanide. Before adding ACh, MCT in the bumetanide-treated group (1.0 ± 0.2 mm/min) was significantly lower than in the control group (3.8 ± 1.1 mm/min). ACh addition significantly increased MCT in both groups, but there was no significant difference between the bumetanide-treated group (21.4 ± 1.7 mm/min) and control group (19.5 ± 3.4 mm/min). These results indicate that ACh-stimulated MCT has greater dependence on HCO3− secretion, whereas the basal MCT rate has greater dependence on Cl− secretion.

Tramadol, a broadly in recent years, is an effective analgesic agent for the treatment of moderate to acute pain. Its metabolites are excreted by the kidney which may cause nephrotoxicity. Moringa oleifera leaves are commonly used to provide herbal and plant-derived medicinal products especially in developing nations. The present study was carried out to determine the biochemical and histopathological changes in the kidney of tramadol-treated albino mice and to evaluate the possible protective role of Moringa oleifera leaves against tramadol-induced nephrotoxicity. Twenty adult albino mice were divided into four groups. Control group (group i) received daily intraperitoneal injection of normal saline only, group ii received oral dose of Moringa oleifera leaves extract (20 mg/kg/bw) for three weeks, group iii received daily intraperitoneal dose of tramadol (0.3 mg/kg/bw) for the same period, group iv, received daily oral dose of Moringa oleifera leaves extract, (20 mg/kg/bw) three hours before injecting intraperitoneal dose of tramadol (0.3 mg/kg/bw), for the same period. Blood samples were withdrawn at the end of the experiment for kidney function tests and specimens from the kidney were processed for histological study. No significant differences in the mean values of the kidney function tests were noticed between Moringa oleifera group and control group. However, there was highly significant increase in the mean values of serum, urea and creatinine in tramadol-treated group as compared to the control group. Although tramadol + Moringa oleifera group revealed significant difference in the mean values of urea and creatinine when compared with tramadol-treated group. So, Moringa oleifera leaves extract have been shown to attenuate the renal dysfunction, improve the renal architecture, with nearly normalization of serum urea and creatinine levels which indicate improvement of renal function. In conclusion, in the light of biochemical results and histological findings, co-administration of Moringa oleifera leaves lessened the negative effects of tramadol-induced nephrotoxicity; possibly by its antioxidant action. Further investigation of these promising protective effects of Moringa oleifera leaves against tramadol-induced renal injury may have considerable impact on developing an adjunct therapy aiming to improve the therapeutic index of some nephrotoxic drugs.

Introduction: Atrophic vaginitis is a common problem in postmenopausal women and results from decreased levels of blood estrogen. It is associated with symptoms of itching, burning, dyspareunia, and postmenopausal bleeding. The present study evaluated the effects of fenugreek extract on atrophic vaginitis. Materials and Methods: This randomized controlled clinical trial was performed on 60 postmenopausal women in Ardabil, Iran, in 2018. The participants were selected using block randomization with the allocation ratio 1:1. Those in the intervention group received 0.5g (the applicator filled to the half-full mark) fenugreek vaginal cream 5% twice a week for 12 weeks. The control group received conjugated estrogens vaginal cream at the dose of 0.625 mg (the applicator filled to the half-full mark) containing 0.3 mg of conjugated estrogens. Atrophic vaginitis was evaluated before and after the treatment through clinical examination, clinical signs, and measurement of Vaginal Maturation Index (VMI). Findings: After the 12-week intervention and modification of the baseline score, the mean (standard error) score for atrophic vaginitis signs was 3.100 (1.43-4.75). This difference was statistically significant in intragroup comparison and in favor of the control group in intergroup comparison (p=0.001). VMI was less than 49% in 86.7% and 46.7% of the participants in the intervention and control groups, respectively. This was a significant difference in favor of the control group (p=0.001). Conclusion: The results of this study showed that total fenugreek extract could be effective in treating signs of atrophic vaginitis, but it was not as effective as ultra-low-dose estrogen.

AbstractIn some applications, researchers using the synthetic control method (SCM) to evaluate the effect of a policy may struggle to determine whether they have identified a “good match” between the control group and treated group. In this paper, we demonstrate the utility of the mean and maximum Absolute Standardized Mean Difference (ASMD) as a test of balance between a synthetic control unit and treated unit, and provide guidance on what constitutes a poor fit when using a synthetic control. We explore and compare other potential metrics using a simulation study. We provide an application of our proposed balance metric to the 2013 Los Angeles (LA) Firearm Study [9]. Using Uniform Crime Report data, we apply the SCM to obtain a counterfactual for the LA firearm-related crime rate based on a weighted combination of control units in a donor pool of cities. We use this counterfactual to estimate the effect of the LA Firearm Study intervention and explore the impact of changing the donor pool and pre-intervention duration period on resulting matches and estimated effects. We demonstrate how decision-making about the quality of a synthetic control can be improved by using ASMD. The mean and max ASMD clearly differentiate between poor matches and good matches. Researchers need better guidance on what is a meaningful imbalance between synthetic control and treated groups. In addition to the use of gap plots, the proposed balance metric can provide an objective way of determining fit.

Musical Cues

Previous research has examined the utilisation of musical cues to improve the performance of cardiopulmonary resuscitation (CPR) delivered in training environments. We postulated a musical cue that is both contemporary and transcends cultures may improve CPR performance. Our aim was to establish whether chest compressions are performed with improved rate and depth if a song of a fixed beat (PinkFong’s ‘Baby Shark’ with a tempo of 115 beats per minute (bpm) and 15 beats in each verse) is played to a healthcare professional immediately before undertaking CPR compared to whale noises (a non-metronomic rhythm). 58 Participants of a paediatric conference (majority doctors) were randomly assigned to listen to a minute of Baby Shark (28) or whale song (30) and then undertake a minute of CPR. There was no significant difference in the mean compression rate between the Baby Shark and control groups, with the groups achieving 121 and 125 bpm, respectively (p=0.18). In relation to compression depth within the target zone, the Baby Shark group had more compressions completed within the target zone (55%) than the control group (39%) although this difference was not significant (p=0.08). Listening to Baby Shark prior to undertaking simulated CPR does not improve overall performance, but there is a potential tendency to improve adequate compression depth which may be beneficial in training exercises.

Purpose: To evaluate and compare corneal hysteresis (CH), corneal resistance factor (CRF), and central corneal thickness (CCT), measurements were taken between a healthy population (controls), patients diagnosed with glaucoma (DG), and glaucoma suspect patients due to ocular hypertension (OHT), family history of glaucoma (FHG), or glaucoma-like optic discs (GLD). Additionally, Goldmann-correlated intraocular pressure (IOPg) and corneal-compensated IOP (IOPcc) were compared between the different groups of patients. Methods: In this prospective analytical-observational study, a total of 1065 patients (one eye of each) were recruited to undergo Ocular Response Analyzer (ORA) testing, ultrasound pachymetry, and clinical examination. Corneal biomechanical parameters (CH, CRF), CCT, IOPg, and IOPcc were measured in the control group (n = 574) and the other groups: DG (n = 147), FHG (n = 78), GLD (n = 90), and OHT (n = 176). We performed a variance analysis (ANOVA) for all the dependent variables according to the different diagnostic categories with multiple comparisons to identify the differences between the diagnostic categories, deeming p < 0.05 as statistically significant. Results: The mean CH in the DG group (9.69 mmHg) was significantly lower compared to controls (10.75 mmHg; mean difference 1.05, p < 0.001), FHG (10.70 mmHg; mean difference 1.00, p < 0.05), GLD (10.63 mmHg; mean difference 0.93, p < 0.05) and OHT (10.54 mmHg; mean difference 0.84, p < 0.05). No glaucoma suspects (FHG, GLD, OHT groups) presented significant differences between themselves and the control group (p = 1.00). No statistically significant differences were found in the mean CRF between DG (11.18 mmHg) and the control group (10.75 mmHg; mean difference 0.42, p = 0.40). The FHG and OHT groups showed significantly higher mean CRF values (12.32 and 12.41 mmHg, respectively) than the DG group (11.18 mmHg), with mean differences of 1.13 (p < 0.05) and 1.22 (p < 0.001), respectively. No statistically significant differences were found in CCT in the analysis between DG (562 μ) and the other groups (control = 556 μ, FHG = 576 μ, GLD = 569 μ, OHT = 570 μ). The means of IOPg and IOPcc values were higher in the DG patient and suspect groups than in the control group, with statistically significant differences in all groups (p < 0.001). Conclusion: This study presents corneal biomechanical values (CH, CRF), CCT, IOPg, and IOPcc for diagnosed glaucoma patients, three suspected glaucoma groups, and a healthy population, using the ORA. Mean CH values were markedly lower in the DG group (diagnosed with glaucoma damage) compared to the other groups. No significant difference was found in CCT between the DG and control groups. Unexpectedly, CRF showed higher values in all groups than in the control group, but the difference was only statistically significant in the suspect groups (FHG, GLD, and OHT), not in the DG group.
