Background: Traumatic brain injury (TBI) is a common healthcare problem related to disability. An easy-to-use trauma scoring system informs physicians about the severity of trauma and helps to decide the course of management. The purpose of this study is to use the combination of both physiological and anatomical assessment tools that predict the outcome and develop a new modified prognostic scoring system in TBIs. Patients and methods: A total of 181 subjects admitted to the emergency department (ED) of Sanglah General Hospital were documented for both Marshall CT scan classification score (MCTC) and Revised Trauma Score (RTS) upon admission. Glasgow Outcome Scale (GOS) was then documented at six months after brain injury. A new Modified Revised Trauma–Marshall score (m-RTS) was developed using statistical analytic methods. Results: The total sample enrolled for this study was 181 patients. The mean RTS upon admission was 10.2±1.2. Of the 181 subjects, 110 (60.8%) were found to have favorable GOS (GOS score >3). Best Youden’s index results were obtained with any of the RTS of ≤10 with area under receiver operating characteristic (ROC) curve of 0.2542 and with risk ratio of 2.9 (95% CI=1.98−4.28; P=0.001); and Marshall score ≤2 with area under ROC curve of 0.2249 with risk ratio of 3.9 (95% CI=2.52−5.89; P=0.001). The RTS–Marshall combination has higher sensitivity with risk ratio of 4.5 (CI 95%=2.55−8.0; P=0.001) for screening tools of unfavorable outcome. The Pearson’s correlation between RTS and Marshall classification is 0.464 (P<0.001). Conclusion: Combination of physiological and anatomical score improves the prognostic of outcome in moderate and severe TBI patients, formulated in this accurate, simple, applicable and reliable m-RTS prognostic score model.

AIM: The purpose of this study was to determine the antibacterial activity of Lumbricus rubellus earthworms through inhibitory zone diameter to the growth of the bacterium Phorphyromonas gingivalis as the cause of periodontitis. METHODS: This was an experimental study with randomised posttest-only control group design. The study was conducted at the Microbiology Research Center laboratory at the Faculty of Dentistry, Airlangga University, Indonesia. The study was conducted in vitro, the sample size was calculated using the Federer formula as many as four agar plates containing bacteria Phorphyromonas gingivalis, with each plate given five different treatments: control (ethanol), Lumbricus rubellus earthworm extract (ECT) with concentrations of 50%, 25%, 12.5%, and 6.25% respectively. The data in the form of inhibition zone diameter (measured in millimetres) obtained were tested using One-Way ANOVA. RESULTS: The mean diameter of the inhibitory zone extract of Lumbricus rubellus earthworm on the growth of Phorphyromonas gingivalis bacteria in the treatment group had significant differences (p < 0.05). The mean inhibition zones between controls and the ECT treatment group (ECT 50%, ECT 25%, ECT 12.5%) were statistically different (p < 0.05), in contrast with ECT 6.25% (p > 0.05) which did not show significant difference with the control group (p > 0.05). CONCLUSION: Lumbricus rubellus earthworm extract with a concentration of 50% has the largest diameter of the inhibitory zone on the growth of the Phorphyromonas gingivalis bacteria. The 6.25% earthworm extract showed no antibacterial activity against the growth of Phorphyromonas gingivalis bacteria.

BACKGROUND: The pathogenesis of inflammatory neuronal cell damage will continue after traumatic brain injury in which contributed to subsequent mortality. Serum S100B levels were shown to be an early predictor of mortality due to traumatic brain injury. AIM: This Meta-Analysis will analyse the mean and diagnostic strength of serum S100B levels between survived and died subjects with head injuries based on the various follow-up times of nine studies. METHODS: We conducted a meta-anelysis in accordance with PRISMA guidelines and adhering to Cochrane Handbook for Systematic Review of Interventions. Literature search was conducted on March 16, 2018 from Medline and Scopus in the past 10 years, using various keywords related to S100, brain injury, and outcome. Duplicate journals were sorted out via EndNote. Included articles were as follows: original data from the group, clinical trials, case series, patients undergoing serum S100B levels with both short- and long-term follow-up mortality. Data were collected for mortality, serum S100B levels, and its diagnostic strength. All data were analyzed using Review Manager 5.3 (Cochrane, Denmark). RESULTS: The results of the meta-analysis showed a significant difference in S100B levels between survived and died subjects with head injuries on overall follow-up timeline (0.91, 95.9% CI 0.7-1.12, I2 = 98%, p < 0.001), during treatment (1.43, 95% CI 0.97 to 1.89, I2 = 98%, p < 0.001), or 6 months (0.19; 95%CI 0.1-0.29, I2 = 76%, p < 0.001) with an average threshold value that varies according to the study method used. The mean diagnostic strength was also promising to predict early mortality (sensitivity of 77.18% and 92.33%, specificity of 78.35% and 50.6%, respectively). CONCLUSION: S100B serum levels in the future will be potential biomarkers, and it is expected that there will be standardised guidelines for their application.

Background We aimed to synthesize the latest evidence on the efficacy and safety of decompression alone compared to decompression with fusion in patients with lumbar spondylolisthesis. We also aimed to evaluate factors affecting the efficacy and complications. Methods A systematic literature search was conducted using PubMed, Scopus, Europe PMC, Cochrane Central Database, and ClinicalTrials.gov. The main outcome was improvement in Oswestry Disability Index (ODI). The secondary outcome was back pain and leg pain improvement, complications, reoperation rate, duration of surgery, length of hospital stay, and blood loss. Results There were 3993 patients from 13 studies. Decompression with fusion was associated with greater reduction in ODI (mean difference 4.04 [95% CI 0.95, 7.13], P = 0.01) compared to decompression alone. Greater reduction in back (standardized mean difference [SMD] 0.27 [95% CI 0.00, 0.53], P = 0.05) and leg pain (SMD 0.13 [95% CI 0.06, 0.21], P < 0.001) was observed in the decompression with fusion group. Complications were similar in the 2 groups (OR 0.60 [95% CI 0.34, 1.04], P = 0.07). The reoperation rate was similar in both groups (P = 0.54). Decompression alone resulted in shorter duration of surgery (mean difference −85.18 minutes [95% CI −122.79, −47.57], P < 0.001), less blood loss (mean difference −262.65 mL [95% CI −313.45, −211.85], P < 0.001), and shorter hospital stay (mean difference −2.64 days [95% CI −3.58, −1.70], P < 0.001). Empirical Bayes random-effects meta-regression showed that the rate of complication was influenced by age (coefficient 0.172, P = 0.004). Conclusion Decompression with fusion had greater efficacy than decompression alone but was associated with more blood loss, lengthier surgery, and hospitalization. In terms of complications, decompression alone may be beneficial in younger patients. (PROSPERO CRD42020211904) Level of Evidence 2A.
