A man was found lying dead next to a ladder, with only a laceration surrounded by an abrasion visible upon external examination. No skull fractures were palpable. A CT scan and MRI showed a Jefferson fracture of the atlas, associated to a posterior displacement of the skull, a fracture of the dens of the axis, and fractures of the bodies of C5 and C6. Jefferson fractures typically result from a blow to the apex of the skull. In such cases, forensic pathologists should suspect the existence of a Jefferson fracture, particularly when no severe injuries are visible externally.A new "single-plate method" is presented for measuring the modulation transfer function (MTF) in magnetic resonance imaging (MRI). This method sets a slice plane perpendicular to a single-plate phantom to eliminate contamination effects from the direction perpendicular to the measurement direction in the image plane, which occur with a conventional ramp method. As no practical method for measuring the MTF has been established for MRI, we examined whether the MTF can be measured practically using the single-plate method for various fast imaging sequences. Furthermore, the MTFs of T1-weighted (T1W) fast spin echo (FSE) and conventional spin echo (CSE) images obtained using the single-plate method and ramp method were compared. The measured MTFs of T1W CSE images revealed rectangular shapes with a sharp decrease near the Nyquist cutoff frequency in both phase-encoding (PE) and frequency-encoding (readout, RO) directions. The measured MTFs of T1W FSE images obtained with centric-order acquisition showed symmetric step-function shapes reflecting k-space segmentation determined by the echo train length (ETL). The measured MTFs of T2-weighted (T2W) FSE images showed asymmetric step-function shapes reflecting differences in T2 decay of signals from samples. The MTFs obtained using the single-plate method significantly reduced the collapse caused by the contamination effect, which is observed in all the MTF measurements of the ramp method. The proposed "single-plate method" simplified the complicated MTF measurement procedure and eliminated the contamination effect. This method is expected to be useful for evaluating the resolution properties of MR fast imaging techniques with a complicated k-space trajectory.

To prospectively evaluate the feasibility of single-stage bariatric surgery in patients with super-super obesity and compare their outcomes with patients undergoing intra-gastric balloon insertion as a bridging device prior to definitive surgery.

Data from 42 patients with BMI 60-75kg/m

who underwent either intra-gastric balloon insertion followed by sleeve gastrectomy (two-stage group); or attempted bariatric surgery as a single-stage procedure were compared.

All patients in the single-stage group underwent successful bariatric surgery. Length of hospital stay after definitive bariatric surgery (3.3 ± 1.9 vs 2.2 ± 0.6days, p = 0.005) and overall complication rates were significantly higher in the two-stage group.

Routine use of an intra-gastric balloon in super-super obese patients is not required and may be associated with poorer peri-operative outcomes and delayed weight loss.

Bariatric surgery is no longer considered only as a weight loss surgery but also a way of treating obesity-related comorbidities such as type 2 diabetes mellitus (T2DM). Short-term T2DM remissions in patients undergoing laparoscopic sleeve gastrectomy (LSG) have been shown, but there are very few reports on the mid-term results. We aimed to assess the remission rate of T2DM in obese patients after LSG throughout 5-year follow-up.

We performed a retrospective multicenter cohort analysis of 240 patients who underwent LSG. We assessed the remission rate of T2DM 1year and 5years after surgery.

Forty-six percent of patients achieved T2DM remission 5years after LSG. The remission group had better weight loss results (median% of total weight loss 5years after 30.1% (22.9-37.0) vs 23.0% (13.7-30.2), p < 0.001) and were significantly younger than the no remission group (43 (38-52) vs 52 (44-58) years, p < 0.001). Duration of T2DM was significantly shorter (2 (1-5) vs 5 (3-10) years, p < 0.001) with less insulin requirement and less diabetes-related complications (7.2% vs 19.8%, p < 0.001) and significantly lower median DiaRem score (4.0 (IQR 2.0-6.0) vs 12.0 (IQR 5.0-16.0), p< 0.001). selleck products Preoperative body mass index (BMI) had no effect on remission.

Our study suggests that diabetes remission after laparoscopic sleeve gastrectomy occurs frequently, and in the 5-year follow-up, it may remain at the level of 46%. We identified the age of patients, duration, and severity of T2DM as factors affecting mid-term diabetes remission. Nevertheless, further well-designed trials are needed to support our findings.

Autophagy is a membrane driven process and tightly regulated by membrane-associated proteins. Here, we summarized membrane lipid composition, and membrane-associated proteins relevant to autophagy from a spatiotemporal perspective. In particular, we focused on three important membrane remodeling processes in autophagy, lipid transfer for phagophore elongation, membrane scission for phagophore closure, and autophagosome-lysosome membrane fusion. We discussed the significance of the discoveries in this field and possible avenues to follow for future studies. Finally, we summarized the membrane-associated biochemical techniques and assays used to study membrane properties, with a discussion of their applications in autophagy.

In case of untreatable suffering at the end of life, continuous sedation until death (CSD) may be the only treatment option left. Because these patients cannot communicate anymore, caregivers have to rely on behavioral observation to assess the patient's comfort. Recently, however, a number of studies from the neurosciences have shown that sometimes consciousness and pain are undetectable with these traditional behavioral methods. The aim of this study was to find out if subjective caregiver assessments of consciousness and pain would be confirmed by objective neurophysiological measures.

In this prospective observational study, we observed patients from the start of palliative sedation until death. Subjective caregiver assessments of level of consciousness and pain based on behavioral observations were compared with objective measures from neurophysiological monitoring devices.

We collected and analyzed 108 subjective caregiver assessments in a sample of 12 patients and 32 assessments by traditionally tered retrospectively at Clinical-Trials.gov (ID NCT03273244).Detail morphological evaluation for ASD is essential to achieve successful transcatheter closure. Three-dimensional transesophageal echocardiography (3D-TEE) is emerging, but few studies have comprehensively verified the usefulness of 3D-TEE. We divided 329 patients who underwent transcatheter ASD closure at our university hospital into 157 in the Conventional group evaluated with 2-dimensional transesophageal echocardiography and balloon sizing (BS), and 172 in the 3D-TEE group evaluated with 3D-TEE additionally. We assessed usefulness of 3D-TEE and consider appropriate device selection procedure. Overall, the percentage with re-sizing of device tended to be lower in the 3D-TEE group than in the Conventional group (10.1% vs 6.0%, p = 0.187). Among preprocedural modalities, the device size was mainly decided based on the BS diameter. A logistic regression analysis demonstrated that large atrial septum aneurysms (ASA) were associated with a ≥ 2 mm discrepancy of the BS diameter from the preprocedural 3D-TEE diameter (p  less then  0.05). Compared to the Amplatzer Septal Occluder, the differences in device size and the preprocedural ASD measurement were greater when using the Occlutech Figulla Flex II Occluder (FFII). Particularly, among the patients implanted with FFIIs, the discrepancies of the device size from the 3D-TEE measurement were greater in patients with large ASA than those with small ASA. Preprocedural 3D-TEE is useful to select the appropriate device size. Particularly, it is necessary to select a much larger device than that derived from the preprocedural 3D-TEE measurement when using FFII in patients with a septal aneurysm.To investigate the feasibility of pre-procedural morphological assessment of coronary artery calcification in severely calcified lesions with electrocardiography (ECG)-gated non-contrast computed tomography (CT). link2 Severely calcified coronary arteries in patients who underwent ECG-gated non-contrast CT prior to optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) were studied retrospectively. CT and OCT data were co-registered by marking landmark structures such as side branches and reviewed side by side with cross-sectional images. The maximum calcium angle (MCA) and presence of nodular calcification (NC) were evaluated. A total of 496 cross-sections in 16 lesions were included in this analysis. The Pearson correlation coefficient between CT- and OCT-derived MCA was 0.92 (p  270 degrees were 90.3%, 79.7%, 92.1%, and 97.4%, respectively. Sensitivity, specificity, and positive and negative predictive values of CT in identifying NC were 73.3%, 97.5%, 47.8%, and 99.2%, respectively. ECG-gated non-contrast coronary CT might be helpful to obtain detailed information of severe coronary artery calcification before PCI.For control of COVID-19, community immunity is required, necessitating widespread immunization. COVID-19 vaccines are coming to Canada, with the government announcing in August 2020 agreements with four different companies for their COVID-19 vaccine if their trials are successful. Never before has public health had to rapidly develop a vaccine introduction program for multiple new but differing vaccines with the added pressure that the program is needed across all ages and in all Canadian communities and there is high probability of not enough vaccine to go around at the start. Traditional public health vaccine introduction planning will need to be both accelerated and more comprehensive to ensure optimal uptake across the country. link3 This overview highlights a number of points for consideration by public health in their planning for COVID-19 vaccines before these COVID-19 vaccines are available, once they are available, once supplies are plentiful, and throughout the vaccine program. Targeted and tailored communications are key elements needed to reach and positively influence diverse communities, regions, ages, languages, education levels and lived experiences.
