8549 Background: Timing and frequency of non occlusive (nO) or occlusive (O) CVCrT in cancer patients (pts) remain unclear. In this randomized controlled trial we studied these points and evaluated the efficacy and safety of short-term prophylaxis with A or D in the prevention of CVCrT. Methods: Consecutive cancer pts without contraindications to short-term anticoagulation, scheduled for chemotherapy via CVC, were randomly assigned to receive: A 1 mg/day for 3 days before and 8 days after CVC insertion; D 5,000 IU 2 hours before and daily for 8 days after CVC insertion; no anticoagulant treatment (NT). All pts underwent venography (V) at day 8 and 30 after CVC insertion and then every two months until CVC removal . The primary endpoint was V detected CVCrT, evaluated as nO or O when it was partially or completely occlusive of the vein lumen, respectively. Bleeding episodes were recorded. Proportions were compared using chi-square test together with odds ratio (OR). Results: 450 pts were randomized, 348 of whom (120/150 A, 114/150 D, and 114/150 NT) underwent V (median number of procedures 4, range 2–8). Both A and D reduced the frequency of V detected CVCrT (21.9% A vs 55.3% NT, OR= 4.35 (95% CI 2.43–7.69), p<0.001; 40% D vs 55.3% NT, OR= 1.85 (95% CI 1.10–3.13), p=0.02). A was more effective than D (OR= 2.37 (CI 1.34–4.22), p= 0.003). The frequency of O CVCrT was not different in the 3 groups (0.9% A, 5.0% D, 4.4% NT; p= 0.18). Overall, 5.1% of pts with CVCrT were symptomatic, all presenting O CVCrT (42% of pts with O CVCrT were not symptomatic). Most CVCrTs (95.6%) were observed at day 8 after CVC insertion. No major bleeding or pulmonary embolism occurred. Conclusions: In this study, acenocumarine was more effective than dalteparine in reducing V detected CVCrT. The doses of prophylactic agents used in this study proved to be safe. Symptomatic CVCrT evaluation alone underestimates the actual CVCrT frequency. The first days following CVC insertion are at highest risk for CVCrT. Short term thrombosis prophylaxis appears to be superior to no treatment without the expenses and inconveniences inherent in long-term prophylaxis. No significant financial relationships to disclose.

Treatment of dental caries in children still remains challenging due to lack of cooperation with conventional treatment modalities. Recently, the use of Silver Diamine Fluoride (SDF) has proved useful in addressing this challenge. Aim: This clinical trial aimed to evaluate the effectiveness of Silver Diamine Fluoride (SDF) in arresting caries in children in Lagos, Nigeria. Methods: This was a phase III balanced randomized controlled school based interventional study on 240 children. The study group was treated with SDF while GIC was used in the control group. Follow up visits in 2 weeks, 1 month, and 3 months were carried out to assess the treatment outcome. Inferential statistics with the use of Pearson Chi-square test and Independent Student t-test were used at 5% level of significance. Results: There was significant relationship between SDF and caries arrest in 2 weeks, 1 month and 3 months’ assessment period (p = 0.001). The control group showed continuous decline (71.7%, 54.3% and 50.9%) in restorative success from 2 weeks to 3 months respectively. The mean ± SD and Confidence Interval (CI) of arrested caries in the SDF group were 113± 1.24 and 113.1 – 113.5 respectively. In the control group the mean ± SD and CI of restorative success were 69.3±11.8 and 67.2 – 71.4. The effect size was 5.24. Conclusion: The result of the study showed that SDF was effective in arresting caries in children without any harm and there was statistically significant difference in the use of 38% SDF in arresting caries in children.

Objective To compare low doses of pethidine with dipyrone in labor analgesia. Methods In a randomized prospective study conducted by Universidade de Fortaleza, in the state of Ceará, Brazil, between May and December 2016, 200 full-term parturients, with very painful uterine contractions and exhibiting uterine cervix dilatation ≥ 5 cm, were selected to receive a single intravenous dose of either 0.25 mg/kg of pethidine (n = 100) or of 25 mg/kg of dipyrone (n = 100). Pain was assessed using the visual analogue scale. The data were analyzed using the Student t-test, the chi-square test and the likelihood ratio. Results There was a significant improvement in pain in 35% of the parturients. Both drugs presented a similar analgesic effect 1 hour after the intervention (p = 0.692). There was no analgesic effect during the evaluation of the second hour after the intervention with pethidine or dipyrone. There were no adverse effects, such as maternal drowsiness, nausea or vomiting, related to the drugs used. Conclusion Pethidine in low doses and dipyrone presented equivalent analgesia during labor.

Abstract Background Spinal anesthesia using the midline approach might be technically difficult in geriatric population. We hypothesized that pre-procedural ultrasound (US)-guided paramedian technique and pre-procedural US-guided midline technique would result in a different spinal anesthesia success rate at first attempt when compared with the conventional landmark-guided midline technique in elderly patients. Methods In this prospective, randomized, controlled study, one hundred-eighty consenting patients scheduled for elective surgery were randomized into the conventional surface landmark-guided midline technique (group LM), the pre-procedural US-guided paramedian technique (group UP), or the pre-procedural US-guided midline technique (group UM) with 60 patients in each group. All spinal anesthesia were performed by a novice resident. Results The successful dural puncture rate on first attempt (primary outcome) was higher in groups LM and UM (77 and 73% respectively) than in group UP (42%; P < 0.001). The median number of attempts was lower in groups LM and UM (1 [1] and 1 [1–1.75] respectively) than in group UP (2 [1, 2]; P < 0.001). The median number of passes was lower in groups LM and UM (2 [0.25–3] and 2 [0–4]; respectively) than in group UP (4 [2–7.75]; P < 0.001). The time taken to perform the spinal anesthesia was not different between groups LM and UM (87.24 ± 79.51 s and 116.32 ± 98.12 s, respectively) but shorter than in group UP (154.58 ± 91.51 s; P < 0.001). Conclusions A pre-procedural US scan did not improve the ease of midline and paramedian spinal anesthesia as compared to the conventional landmark midline technique when performed by junior residents in elderly population. Trial registration Retrospectively registered at Clinicaltrials.gov, registration number NCT02658058, date of registration: January 18, 2016.

Abstract Objective To evaluate the short-term patient satisfaction, compliance, disease control and infection risk of telemedicine (TM) compared with standard in-person follow-up (FU) for patients with lupus nephritis (LN) during COVID-19.Methods This was a single-center open-label randomized controlled study. Consecutive patients followed at the LN clinic were randomized to either TM or standard FU (SF) group in a 1:1 ratio. Patients in the TM group received FU via videoconferencing. SF group patients continued conventional in-person outpatient care. The 6-month data were compared and presented.Results From June to December 2020, 122 patients were randomized (TM: 60, SF: 62) and had at least 2 FUs. There were no baseline differences, including SLEDAI-2k and proportion of patients in lupus low disease activity state (LLDAS), between the 2 groups except a higher physician global assessment score (PGA) in the TM group. After a mean FU of 19.8 ± 4.5 weeks, the overall patient satisfaction score was higher in the TM group. More patients in the TM group had hospitalization (15/60, 25.0% vs 7/62, 11.3%; p = 0.049) with higher baseline PGA (OR = 1.15, 95% CI 1.07–1.23) being the independent predictor. The proportions of patients remained in LLDAS were similar in the 2 groups (TM: 75.0% vs SF: 74.2%, p = 0.919). None of the patients had COVID-19.Conclusion TM FU resulted in better patient satisfaction and similar short-term disease control in patients with LN compared to standard care. However, it was associated with more hospitalizations and might need to be complemented by in-person visits especially in patients with higher PGA.
