To explore the relationships between clinical-radiological features and surgical outcomes in subjects with interhemispheric cysts (IHC) and corpus callosum anomalies.

We reviewed the clinico-radiological and neurosurgical data of 38 patients surgically treated with endoscopic fenestration, shunting, or combined approaches from 2000 to 2018 (24 males, median age 9years). Pre- and postoperative changes in IHC volume were calculated. Outcome assessment was based on clinico-radiological data. Group comparisons were performed using χ

, Fisher exact, Mann-Whitney U, and Kruskal-Wallis tests.

Median age at first surgery was 4months (mean follow-up 8.3years). Eighteen individuals (47.3%) required > 1 intervention due to IHC regrowth and/or shunt malfunction. Larger preoperative IHC volume (P = .008) and younger age at surgery (P = .016) were associated with cyst regrowth. At last follow-up, mean cystic volume was 307.8 cm

, with IHC volume reduction > 66% in 19/38 (50%) subjects. The neurological outcome was good in 14/38 subjects (36.8%), fair in 18/38 (47.3%), and poor in 6/38 (15.7%). LXH254 cost There were no differences in the postoperative cyst volume with respect to either the type of first surgery or overall surgery type. Higher absolute postoperative IHC reduction was observed in subjects who underwent both IHC fenestration and shunting procedures (P < .0001). No differences in neurological outcome were found according to patient age at surgery or degree of IHC reduction.

Endoscopic fenestration and shunting approaches are both effective but often require multiple procedures especially in younger patients. Larger IHC are more frequently complicated by cyst regrowth after surgery.

However, the elemental composition of mineral dust arising locally from construction activities and aeolian soil resuspension overlaps with African dust. Therefore, we derived a novel "isotope-resolved chemical mass balance" (IRCMB) method by employing radiogenic strontium, neodymium, and hafnium isotopes to accurately differentiate and quantitatively apportion collinear proximal and synoptic-scale crustal and anthropogenic mineral dust sources. IRCMB was applied to two air masses that transported African dust to Barbados and Texas to track particulate matter (PM) spikes at both locations. During Saharan-Sahelian intrusions, the radiogenic content of urban PM2.5 increased with respect to 87Sr/86Sr and 176Hf/177Hf but decreased in terms of 143Nd/144Nd, demonstrating the ability of these isotopes to sensitively track African dust intrusions even in complex metropolitan atmospheres. The principal aerosol strontium, neodymium, and hafnium end members were concrete dust and soil, soil and motor vehicles, and motor vehicles and North African dust, respectively. IRCMB separated and quantified local soil and distal crustal dust even when PM2.5 concentrations were low, opening a promising source apportionment avenue for urbanized/industrialized atmospheres.

In acute respiratory distress syndrome (ARDS), physiological parameters associated with outcome may help defining targets for mechanical ventilation. This study aimed to address whether transpulmonary pressures (P

), includingtranspulmonary driving pressure (DP

), elastance-derived plateau P

, and directly-measured end-expiratory P

, are better associated with 60-day outcome than airway driving pressure (DP

). We also tested the combination of oxygenation and stretch index [PaO

/(FiO

*DP

)].

Prospective, observational, multicentre registry of ARDS patients. Respiratory mechanics were measured early after intubation at 6kg/ml tidal volume. We compared the predictive power of the parameters for mortality at day-60 through receiver operating characteristic (ROC) and assessed their association with 60-day mortality through unadjusted and adjusted Cox regressions. Finally, each parameter was dichotomized, and Kaplan-Meier survival curves were compared.

385 patients were enrolled 2 [1-4] days from intn obese patients.

Adverse events (AEs) during trauma resuscitation are common and heterogeneity in reporting limits comparisons between hospitals and systems. A recent modified Delphi study established a taxonomy of AEs that occur during trauma resuscitation. This tool was further refined to yield the Safety Threats and Adverse events in Trauma (STAT) taxonomy. The objective of this study was to evaluate the inter-rater reliability of the STAT taxonomy using in-situ simulation resuscitations.

Two reviewers utilized the STAT taxonomy to score 12 in-situ simulated trauma resuscitations. AEs were reported for each simulation and timestamped in the case of multiple occurrences of a single AE. Inter-rater reliability was assessed using Gwet's AC1.

The agreement on all AEs between reviewers was 90.1% (973/1080). The Gwet's AC1 across AE categories were EMS handover (median 0.72, IQR [0.54, 0.82]), airway and breathing (median 0.91, IQR [0.60, 1.0]), circulation (median 0.91, IQR [0.72, 1.0]), assessment of injuries (median 0.80, IQR [0.24, 0.91]), management of injuries (median 1.00, IQR [1.00, 1.00]), procedure related (median 1.00, IQR [81, 1.00]), patient monitoring and IV access (median 1.00, IQR [1.00, 1.00]), disposition (median 1.00, IQR [1.00, 1.00]), team communication and dynamics (median 0.80, IQR [0.62, 1.00]).

The STAT taxonomy yielded 90.1% agreement and demonstrated excellent inter-rater reliability between reviewers in the in-situ simulation scenario. The STAT taxonomy may serve as a standardized evaluation tool of latent safety threats and adverse events in the trauma bay. Future work should focus on applying this tool to live trauma patients.

To evaluate predictive and associated risk factors for nephrectomy in renal trauma and assess a 6-point score for surgical decision-making.

This multicenter, retrospective, and observational study assessed 247 subjects with blunt or penetrating kidney trauma. Kidney injuries were classified according to the American Association for the Surgery of Trauma (AAST) Injury Scoring Scale. Renal trauma was classified as "low-grade" (Grades I-III), Grade IV, and Grade V. Subjects were compared according to conservative treatment (CTrt.) or nephrectomy. Predictive factors were evaluated with a multiple regression model. A 6-point score was evaluated with a ROC analysis.

Patients requiring nephrectomy had a lower mean arterial pressure MAP compared to CTrt, 64.71mmHg (SD ± 10.26) and 73.86 (SD ± 12.42), respectively (p =  < 0.001). A response to IV solutions was observed in 90.2% of patients undergoing CTrt. (p =  < 0.001, OR = 0.211, 95%CI = 0.101-0.442). Blood lactate ≥ 4mmol/L was associated with nephrectomy (p =  < 0.001). A hematoma ≥ 25mm was observed in 41.5% of patients undergoing nephrectomy compared to 20.1% of CTrt. (p = 0.004, OR = 9.29, 95% CI = 1.37-5.58). A logistic regression analysis (p =  < 0.001) showed that blood lactate ≥ 4mmol/L (p = 0.043), an inadequate response to IV solutions (p = 0.041) and renal trauma grade IV-V (p =  < 0.001), predicted nephrectomy. A 6-point score with a cut-off value ≥ 3 points showed 83% sensitivity and 87% specificity for nephrectomy with an AUC of 89.9% (p =  < 0.001).

An inadequate response to IV solutions, a lactate level ≥ 4mmol/L, and grade IV-V renal trauma predict nephrectomy. A score ≥ 3 points showed a good performance in this population.

Experiments were performed using a channel-shaped rubber rail and artificial stones. We compared short pulse mode and long pulse mode in both MM and VBM with the laser tip positioned so that it was touching and at 1 and 2 mm distances from the stone surface. Stone retropulsion was measured after the laser fired for 10 s in three different laser settings 0.5 J/8 Hz, 0.8 J/8 Hz and 1.0 J/8 Hz. When the laser tip was touching the artificial stone, stone retropulsion in MM was significantly shorter than that in VBM in all laser settings (P  less then  0.01, P = 0.02 and P = 0.02, respectively). At 1-mm distance, stone retropulsion in MM was significantly shorter than that in VBM in 0.8 J/8 Hz and 1.0 J/8 Hz settings (P  less then  0.01 and P = 0.01, respectively). At 2-mm distance, however, there were no differences between MM and VBM in stone retropulsion in any laser settings. Stone retropulsion was not significantly different between the laser settings at 1-mm distance in MM, or when touching in VBM. In conclusion, stone retropulsion distance in MM can be shorter than that in VBM. Stone retropulsion in MM and VBM may be differently influenced by laser settings and laser tip position.Therapeutic hypothermia (TH) is effective for neonatal hypoxic-ischemic encephalopathy (HIE). The combination of abnormal myocardial repolarization and fatal arrhythmia in patients with accidental hypothermia has prompted clinical validation of the proarrhythmic potential of TH. However, to our knowledge, there have been few clinical studies on myocardial depolarization and repolarization abnormalities caused by TH in neonates. Therefore, we investigated the effects of TH on neonatal myocardial depolarization and repolarization by capturing the waveform changes in electrocardiograms (ECGs) associated with body temperature (BT) before and after TH. We included three neonates with HIE diagnosed at birth who were treated with TH in our hospital. The heart rate, RR interval, P wave duration, PR interval, QRS duration, QT interval, corrected QT (QTc) interval by Fridericia's formula, J point-T end (JT) interval, corrected JT (JTc) interval by Fridericia's formula, T peak-T end (Tpe) interval, Tpe/QT, and QRS/QTc were calculated retrospectively using an ECG. The correlations of ECG parameters recorded concurrently with 33 samples in which BT measurements were confirmed were performed. BT and heart rate were positively correlated (R 0.589, p = 0.0003). BT was negatively correlated with Tpe/QT (R - 0.470, p = 0.0058), the QTc interval (R - 0.680, p  less then  0.0001), and the corrected JT interval (R - 0.697, p  less then  0.0001). TH does not affect atrial or ventricular depolarization but prolongs the ventricular repolarization process in a temperature-dependent manner.
