Of patients admitted to ICU, 71 (41%) received vasopressor support. This was weaned within 24h in 55 (77%) patients. Patients with larger tumours (> 6cm) and a transfusion requirement are more likely to require prolonged inotropic support. Among patients admitted to the ward, there were no complications that required escalation of care.
Although not widespread practice in Australia and New Zealand, it appears safe for the majority of patients undergoing minimally invasive resection of phaeochromocytoma to be admitted to the ward post-operatively.

Within the international project covid19-nmr, we distribute the spectroscopic analysis of the viral proteins and RNA. Here, we report NMR chemical shift assignments for the protein nsp7. The 83 amino acid nsp7 protein is an essential cofactor in the RNA-dependent RNA polymerase. The polymerase activity and processivity of nsp12 are greatly enhanced by binding 1 copy of nsp7 and 2 copies of nsp8 to form a 160 kD complex. A separate hexadecameric complex of nsp7 and nsp8 (8 copies of each) forms a large ring-like structure. Thus, nsp7 is an important component of several large protein complexes that are required for replication of the large and complex coronavirus genome. We here report the near-complete NMR backbone and sidechain resonance assignment (1H,13C,15N) of isolated nsp7 from SARS-CoV-2 in solution. Further, we derive the secondary structure and compare it to the previously reported assignments and structure of the SARS-CoV nsp7.
Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are useful in determining indications for revascularization of coronary artery disease (CAD). Although the discordance of FFR and iFR was noted in approximately 20%, this cause has not been well established. We investigated patient background and features on coronary CT angiography (CCTA) showing not only FFR- and iFR-positive findings but also discordance between FFR ≤ 0.8 and iFR ≤ 0.89.
Subjects were consecutively treated in 83 cases with 105 vessels in which stenosis of 30-90% was detected at one vessel of at least 2mm or more in the major epicardial vessels and FFR and iFR was performed within subsequent 90days, among suspected CAD which underwent CCTA. The factors affecting not only FFR- and iFR-positive findings, respectively, but also discordance between FFR and iFR was evaluated using logistic regression analysis on per-patient and per-vessel basis.
FFR- and iFR-positive findings were observed in 42 vessels (40.0%) and 34 ves-positive, iFR-negative patients among those with discordance between the FFR and iFR.Elevated serum uric acid level was reportedly associated with greater coronary lipid plaque. Xanthine oxidoreductase (XOR) is a rate-limiting enzyme in purine metabolism and believed to play an important role in coronary atherosclerosis. However, the relation of XOR to coronary lipid plaque and its mechanism are unclear. Patients with stable coronary artery disease undergoing elective percutaneous coronary intervention under near-infrared spectroscopy intravascular ultrasound (NIRS-IVUS) guidance were prospectively enrolled. They were divided into three groups according to serum XOR activities low, normal, and high. Coronary lipid core plaques in non-target vessels were evaluated by NIRS-IVUS with lipid core burden index (LCBI) and a maximum LCBI in 4 mm (maxLCBI4mm). Systemic endothelial function and inflammation were assessed with reactive hyperemia index (RHI) and high-sensitivity C-reactive protein, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio. Of 68 patients, 26, 31, and 11 were classified as low, normal, and high XOR activity groups. LCBI (474.4 ± 171.6 vs. 347.4 ± 181.6 vs. 294.0 ± 155.9, p = 0.04) and maxLCBI4mm (102.1 ± 56.5 vs. 65.6 ± 48.5 vs. 55.6 ± 37.8, p = 0.04) were significantly higher in high XOR group than in normal and low XOR groups. Although RHI was significantly correlated with body mass index, diabetes, current smoking, and high-density lipoprotein cholesterol, no relation was found between XOR activity and RHI. There were also no relations between XOR activity and C-reactive protein, neutrophil-to-lymphocyte ratio, or platelet-to-lymphocyte ratio. In conclusion, elevated XOR activity was associated with greater coronary lipid core plaque in patients with stable coronary artery disease, without significant relations to systemic endothelial function and inflammation.This research describes the risk of death in elderly after hip fracture according to their strength, measured by hand grip. The result is that the weaker the patient, the greater the risk of death after hip fracture, highlighting the need to assess the force in those patients. For the coming years, most of hip fractures will occur in developing countries. It has been described that low muscular strength, measured by grip strength, increases the risk of mortality in those with hip fracture, in both high-and low- income countries. The objective of this study was to determine the mortality among patients with hip fracture and lower hand grip strength (HGS).
We conducted a cohort and longitudinal study at Hip and Pelvic Surgery Department of a tertiary hospital, in Monterrey, Mexico. The study included patients aged over of 69, admitted for hip fracture surgery from February 1st 2013 to July 31st 2014. HGS measurement was performed by a trained physician at arrival to emergency department prior to surgery; clinimetric variables were asked, and a complete medical history was included.
A total of 670 patients were included in the study and grouped in different tertiles according to hand grip strength. During follow-up, there were 112 deaths (17.4%), 61 (27.5%) in tertile 1, 37 (17.1%) in tertile 2, and 14 (6.8%) in tertile 3, p < 0.001. The association remained significant after adjusting for confounding variables. Selleck EZM0414 Less than 5% of patients discharged from hospital were identified with osteoporosis.
Lower hand grip strength in patients with a hip fracture is associated with high mortality after hip fracture.
