SUMMARY The aim of this prospective, blind, and randomized clinical trial was to assess the effectiveness of repair of localized clinical defects in amalgam restorations that were initially scheduled for replacement. A cohort of 20 patients with 40 (Class I and Class II) amalgam restorations that presented one or more clinical features that deviated from the ideal (Bravo or Charlie) according to US Public Health Service criteria, were randomly assigned to either the repair or the replacement group—A: repair, n = 19; and B: replacement, n = 21. Two examiners who had calibration expertise evaluated the restorations at baseline and 10 years after according to seven parameters: marginal occlusal adaptation, anatomic form, surface roughness, marginal staining, contact, secondary caries, and luster. After 10 years, 30 restorations (75%) were evaluated (Group A: n = 17; Group B: n = 13). Repaired and replaced amalgam restorations showed similar survival outcomes regarding marginal defects and secondary caries in patients with low and medium caries risk, and most of the restorations were considered clinically acceptable after 10 years. Repair treatment increased the potential for tooth longevity, using a minimally interventional procedure. All restorations trend to downgrade over time.

Abstract Background We aimed to determine the efficacy and safety of multiple doses of intravenous tranexamic acid (IV-TXA) on perioperative blood loss in patients with rheumatoid arthritis (RA) who had undergone primary unilateral total knee arthroplasty (TKA). Methods For this single-center, single-blind randomized controlled clinical trial, 10 male and 87 female participants with RA, aged 50–75 years, who underwent unilateral primary TKA were recruited. The patients received one dose of 1 g IV-TXA 10 min before skin incision, followed by articular injection of 1.5 g tranexamic acid after cavity suture during the surgery. The patients were randomly assigned (1:1) into two groups and received an additional single dose of IV-TXA (1 g) for 3 h (group A) or three doses of IV-TXA (1 g) for 3, 6, and 12 h (group B) postoperatively. Primary outcomes were total blood loss (TBL), hidden blood loss (HBL), and maximum hemoglobin (Hb) level decrease. Secondary outcomes were transfusion rate and D-dimer levels. All parameters were measured postoperatively during inpatient hospital stay. Results The mean TBL, HBL, and maximum Hb level decrease in group B (506.1 ± 227.0 mL, 471.6 ± 224.0 mL, and 17.5 ± 7.7 g/L, respectively) were significantly lower than those in group A (608.8 ± 244.8 mL, P = 0.035; 574.0 ± 242.3 mL, P = 0.033; and 23.42 ± 9.2 g/L, P = 0.001, respectively). No episode of transfusion occurred. The D-dimer level was lower in group B than in group A on postoperative day 1 (P <  0.001), and the incidence of thromboembolic events was similar between the groups (P > 0.05). Conclusion In patients with RA, three doses of postoperative IV-TXA further facilitated HBL and Hb level decrease without increasing the incidence of adverse events in a short period after TKA. Trial registration The trial was registered in the Chinese Clinical Trial Registry (ChiCTR1900025013).

BACKGROUND With the growing stress on hospitals caused by the COVID-19 pandemic, the need for home-based solutions has become a necessity to support these overwhelmed hospitals. OBJECTIVE The goal of this study was to compare two nonpharmacological respiratory treatment methods for home-isolated COVID-19 patients using a newly developed telemanagement health care system. METHODS In this single-blinded randomized clinical trial, 60 patients with stage 1 pneumonia caused by SARS-CoV-2 infection were treated. Group A (n=30) received oxygen therapy with bilevel positive airway pressure (BiPAP) ventilation, and Group B (n=30) received osteopathic manipulative respiratory and physical therapy techniques. Arterial blood gases of PaO<sub>2</sub> and PaCO<sub>2</sub>, pH, vital signs (ie, temperature, respiratory rate, oxygen saturation, heart rate, and blood pressure), and chest computed tomography scans were used for follow-up and for assessment of the course and duration of recovery. RESULTS Analysis of the results showed a significant difference between the two groups (<i>P</i>&lt;.05), with Group A showing shorter recovery periods than Group B (mean 14.9, SD 1.7 days, and mean 23.9, SD 2.3 days, respectively). Significant differences were also observed between baseline and final readings in all of the outcome measures in both groups (<i>P</i>&lt;.05). Regarding posttreatment satisfaction with our proposed telemanagement health care system, positive responses were given by most of the patients in both groups. CONCLUSIONS It was found that home-based oxygen therapy with BiPAP can be a more effective prophylactic treatment approach than osteopathic manipulative respiratory and physical therapy techniques, as it can impede exacerbation of early-stage COVID-19 pneumonia. Telemanagement health care systems are promising methods to help in the pandemic-related shortage of hospital beds, as they showed reasonable effectiveness and reliability in the monitoring and management of patients with early-stage COVID-19 pneumonia.

Patients’ esthetic expectations are increasing, and the options of the prosthetic pathways are currently evolving. The objective of this randomized multicenter clinical trial was to assess and compare the esthetic outcome and clinical performance of anterior maxillary all-ceramic implant crowns (ICs) based either on prefabricated zirconia abutments veneered with pressed ceramics or on CAD/CAM zirconia abutments veneered with hand buildup technique. The null hypothesis was that there is no statistically significant difference between the 2 groups. Forty implants were inserted in sites 14 to 24 (FDI) in 40 patients in 2 centers, the Universities of Bern and Geneva, Switzerland. After final impression, 20 patients were randomized into group A, restored with a 1-piece screw-retained single crown made of a prefabricated zirconia abutment with pressed ceramic as the veneering material using the cut-back technique, or group B using an individualized CAD/CAM zirconia abutment (CARES abutment; Institut Straumann AG) with a hand buildup technique. At baseline, 6 mo, and 1 y clinical, esthetic and radiographic parameters were assessed. Group A exhibited 1 dropout patient and 1 failure, resulting in a survival rate of 94.7% after 1 y, in comparison to 100% for group B. No other complications occurred. Clinical parameters presented stable and healthy peri-implant soft tissues. Overall, no or only minimal crestal bone changes were observed with a mean DIB (distance from the implant shoulder to the first bone-to-implant contact) of −0.15 mm (group A) and 0.12 mm (group B) at 1 y. There were no significant differences at baseline, 6 mo, and 1 y for DIB values between the 2 groups. Pink esthetic score (PES) and white esthetic score (WES) values at all 3 examinations indicated stability over time for both groups and pleasing esthetic outcomes. Both implant-supported prosthetic pathways represent a valuable treatment option for the restoration of single ICs in the anterior maxilla ( ClinicalTrials.gov NCT02905838).

We evaluated the effect of keishibukuryogan (KBG; Guizhi-Fuling-Wan), a traditional Japanese (Kampo) formula, on endothelial function assessed by reactive hyperemia peripheral arterial tonometry (Endo-PAT2000) in patients with metabolic syndrome-related factors by controlled clinical trial with crossover design. Ninety-two patients were assigned to group A (first KBG-treatment period, then control period; each lasting 4 weeks, with about one-year interval) or group B (first control, then KBG-treatment). In forty-nine (27, group A; 22, group B) patients completing all tests, the mean value of the natural logarithmic-scaled reactive hyperemia index (L_RHI) increased and those of serum nonesterified fatty acid (NEFA), malondialdehyde, and soluble vascular cell adhesion molecule 1 decreased significantly during the KBG-treatment period, but not during the control period, and 4-week changes of L_RHI, NEFA, and malondialdehyde between the 2 periods showed significance. These results suggest that KBG has beneficial effect on endothelial function in patients with metabolic syndrome-related factors.

Abstract Objective: To determine the effectiveness of Mulligan mobilisation versus Cyriax approach in the management of patients with subacute lateral epicondylitis. Methods: The clinical trial was conducted at the District Headquarter Hospital, Bahawalnagar, Pakistan, from September to December 2018, and comprised lateral epicondylitis patients having symptoms for >2 weeks. The diagnosis was confirmed on the basis of physical tests and musculoskeletal ultrasound. The subjects were randomly allocated to two equal groups A and B. Group A received deep transverse friction and Mill’s manipulation according to Cyriax approach, while group B received Mulligan mobilisation with movement techniques. Patient-related tennis elbow evaluation index was used to collect data which was analysed using SPSS 20. Results: Of the 60 patients, there were 30(50%) in each of the two groups. The overall mean age was 35.27±7.30 years, and 38(63.3%) participants were male.  After 4 weeks of treatment sessions, both groups showed significant improvements (p<0.05) in pain and functional disability scores. Group A showed significantly more improvement (p<0.05) in pain subscale scores compared to group B, while group B showed significant improvement (p<0.05) in functional disability subscale scores compared to group A. There was no significant difference (p>0.05) between the groups on total the patient-related tennis elbow evaluation index score. Conclusion: Both Mulligan mobilisation with movement and Cyriax approach decreased pain and improved functional status in lateral epicondylitis patients.

e21021 Background: Primary progression (PP) and secondary progression (SP) to anti-PD1 therapy (APD) are poorly described in advanced melanoma in real life practice. Hyperprogression with a deleterious effect is reported in many cancers but is poorly assessed in advanced melanoma. Methods: Characteristics of 793 patients treated by APD (nivolumab or pembrolizumab) between July 2014 and May 2018 were collected from MelBase, a prospective French biobank (NCT02828202).We considered: group A (progressive disease as best response), group AHP (hyperprogression) within group A patients (progression/death within 3 months with normal initial LDH and ECOG at baseline, and either ECOG increased from 0 to 3-4, either LDH increased from normal to elevated or both), group B SP (response or stable disease then progression). Characteristics for all and survival for patients alive at progression (AAP) were also described. Results: Median follow-up was 11.3 months (Q1-Q3 4.8–23.6). Characteristics at baseline are in the table. In group A, 14% patients died at progression; within 262 patients AAP, 17% continue APD (the same or switch), 15.1% (CI95 11.1-20.6) were alive 1-year after progression (1YAP); 20.5% for patients in first line and 11.5% for pretreated. In group AHP, 41% patients died at progression; within 48 patients AAP, 12% continue APD, 11.1% (CI95 7.8-13.6) were alive 1YAP. In group B, 11% patients died at progression; within 88 patients AAP, 36% continue APD, 10.3% (CI95 5.2-20.1) were alive 1YAP, 15.9% for patients in first line and 7.0% for pre-treated. Conclusions: Our study shows that PP and SP to APD differ at baseline, but have similar survival rates at progression, while mechanisms involved might be different, providing important landmarks to build second line trials. This study thus highlights the existence of hyperprogressors among which 41% patients died within 3 months, as well as describes their associated characteristics. [Table: see text]

SUMMARY Replacement of dental restorations has been the traditional treatment for restorations that are defective. In this five-year randomized clinical trial, restorations with localized marginal defects were treated with sealants. Thirty-two patients (mean age, 26.8 years) with 126 Class I and Class II restorations with defective margins (amalgam n=69 and resin-based composite n=57) were recruited. Treatment was seal with pit and fissure sealant on localized marginal defects (group A: n=43) and was compared with total restoration replacement (group B: n=40) and untreated restorations (group C: n=43) as negative and positive controls. Restorations were assessed by two examiners using the modified US Public Health Service criteria, observing five clinical parameters: marginal adaptation, roughness, marginal stain, teeth sensitivity, and secondary caries at baseline and at five years after treatment. At the five-year recall examination, 23 patients with 90 restorations (71.4% recall rate) were examined. A significant improvement was observed in the marginal adaptation of the restorations in group A compared with group B. None of the treated group showed trends to downgrade in any parameter. Tooth sensitivity and secondary caries showed a low frequency in all groups. No significant difference in marginal adaptation of the restorations was found between amalgam and resin-based composite restorations (p=0.191). This study demonstrated that marginal sealing of restorations is a minimally invasive treatment that may be used instead of the replacement of restorations with localized marginal defects.

Background: To study the impact of Vitamin A supplementation in anaemia during Pregnancy and thus improving maternal and fetal outcome a Randomized double blind controlled clinical trial was conducted in Department of Obstetrics and Gynaecology, L.L.R.M. Medical college Meerut involving 250 pregnant women in late pregnancy 18-28 weeks with haemoglobin levels <11 g% (7-11 g%)..Methods: The study subjects were divided into two groups: Group A (n=125): Received daily supplement containing Iron (60 mg elemental iron) + Folate (500 mcg) + Vitamin A 20,000 IU weekly for a minimum of 12 weeks. Group B (n=125): Received daily supplement containing iron (60 mg elemental iron) + Folate (500 mcg) for a minimum of 12 weeks.Results: Maximum patients were uneducated belonging to low socioeconomic status. The mean haemoglobin values in Group A and Group B increased from 9.674±1.05 and 9.53±1.04 to 12.2±0.89 and 10.82±1.06 respectively after supplementation. Similarily Serum Ferritin levels increased from 15.96±2.94 and 15.70±2.83 to 78.40±17.82 and 58.64±11.93. Mean corpuscular volume, packed cell volume and red blood cell counts also increased significantly. Maximum haemoglobin levels were achieved with both vitamin A and iron supplementation. The proportion of women who became non anaemic was 97.17% in Group A vs 68.69% in Group B.Conclusions: Vitamin A supplementation improves anaemia and also dramatically improves iron stores in anaemic pregnant women.

Background: Preemptive analgesia is one of the techniques to manage postoperative pain, which increases patient satisfaction and decreases the duration of hospitalization. The present study aimed to evaluate and compare the pain relief achieved by preoperative intravenous ketorolac and oral pregabalin in patients undergoing surgery for mandibular fractures. Methods: In the present clinical trial, 60 patients with unilateral fractures of the mandible were randomly assigned to two groups. In group A, intravenous injections of ketorolac 30 mg and in group B, pregabalin 150 mg capsules were administrated one hour preoperatively. The severity of pain was determined using a visual analog scale (VAS) up to 24 hours postoperatively. Finally, the total doses of an opioid analgesic (pethidine) prescribed for each patient in mg during the first 24 hours and the time for the request of the first analgesic dose in minutes were recorded for each patient. Then, their means were compared between the two groups. Results: Maximum pain severity was experienced immediately after surgery, which decreased gradually during the 24-hour postoperative period (P < 0.0001). The mean severity of pain immediately after regaining consciousness and the mean pain score during the 24-hour postoperative period were lower in the pregabalin group than in the ketorolac group (P < 0.0001). In the ketorolac group, a slightly higher dose of the opioid was administered; however, the difference was not significant (P > 0.05). Conclusions: The oral administration of pregabalin 150 mg one hour preoperatively was more effective than the intravenous administration of ketorolac 30 mg in relieving postoperative pain.
