ABSTRACT
OBJECTIVE@#To assess the predictors and outcomes of acute kidney injury (AKI) among patients with coronavirus disease 2019 (COVID-19).@*OBJECTIVE@#This retrospective observational study was conducted among patients with a confirmed diagnosis of COVID-19 admitted to Hankou Hospital between January, 5 and March 8, 2020. We evaluated the association of AKI with the demographic and biochemical parameters and clinical outcomes of the patients using univariate regression analysis.@*OBJECTIVE@#Atotal of 287 COVID-19 patients, including 55 with AKI and 232 without AKI, were included in the analysis. Compared with the patients without AKI, the patients with AKI were older, predominantly male, and were more likely to have hypoxia and pre-existing hypertension and cerebrovascular diseases. The patients with AKI also had higher levels of white blood cells, D-dimer, aspartate aminotransferase, total bilirubin, creatine kinase, lactate dehydrogenase, procalcitonin, C-reactive protein, a higher prevalence of hyperkalemia, lower lymphocyte counts, and higher chest computed tomographic scores. The incidence of stage 1 AKI was 14.3% and that of stage 2 or 3 AKI was 4.9%. The patients with AKI had much higher mortality rate than those without AKI.@*OBJECTIVE@#AKI is an important complication of COVID-19. An older age, a male gender, multiple pre- existing comorbidities, lymphopenia, increased infection indicators, elevated D-dimer, and impaired heart and liver functions are all potential risk factors ofAKI. COVID- 19 patients with AKI that progresses into stages 2 or 3 AKI have a high mortality rate. Prevention of AKI and monitoring kidney function is critical in the care of COVID-19 patients.

OBJECTIVE@#To explore the clinical characteristics and outcomes of adult critically ill patients with COVID-19 and identify the risk factors correlated with in-hospital deaths.@*METHODS@#This study was conducted among 20 confirmed adult cases of COVID-19 in the Intensive Care Unit (ICU) of Honghu People's Hospital in Jingzhou City, Hubei Province. According to the final outcome, the patients were divided into survivor group and death group with 10 patients each. The demographic data, clinical manifestations and signs, laboratory findings, treatment measures and clinical outcomes were obtained from electronic medical records to compare the clinical characteristics and outcomes between the two groups. Univariate logistic analysis was used to analyze the risk factors associated with in-hospital death.@*RESULTS@#The mean age of patients with confirmed COVID-19 was 70 ± 12 years, and 40% of them were male. The patients were admitted to ICU 11 ± 9 days after symptom onset. The most common symptoms on admission were cough (19 cases), fatigue or myalgia (18 cases), fever (17 cases) and dyspnea (16 cases). Eleven (55%) of the patients had underlying diseases, among which hypertension was the most common (11 cases), followed by cardiovascular disease (4 cases) and diabetes (3 cases). Six (30%) of the patients received invasive mechanical ventilation and continued renal replacement therapy but eventually died. Acute cardiac injury was the most common complication (19 cases). Half of the patients died between the 2nd and 19th day after ICU admission. Compared with dead patients, the surviving patients had a lower average body weight (61.70±2.36 68.60±7.15 kg, =0.01) and a higher Glasgow Coma Index (14.69 ± 0.70 12.70 ± 2.45, =0.03), and were less likely to develop shock (2 10, =0.001) or acute respiratory distress syndrome (2 10, =0.001).@*CONCLUSIONS@#Critically ill patients with COVID-19 are generally older. A higher body weight and a lower lymphocyte count are potentially associated with a greater likeliness of fatality in ICU patients with COVID-19.

Seventy-four patients aged 26-63 yr who had suffered cervicogenic headache for 3 months-21 yr were treated with puked radiofrequency applied to C2 dorsal root ganglion, which is located in the middle of the posterior side of lateral atlantoaxial joint. A trochar was introduced percutaneously under the guidance of X-ray aiming at the target point. As it was inserted through the deep fascia, the stylet was withdrawn and a 10 cm long 22 gauge curved blunt electrode was inserted into the trochar and advanced until the patients felt radiating pain from the point of puncture to occiput. Lateral radiograph was obtained to verify the placement of electrode. The tip of the electrode was usually located in front of spinal canal at the atlantoaxial joint level. Sensory stimulation was performed with 50 Hz and 0.1-0.5 V and the patients could feel radiating pain at occiput. Motor stimulation was performed with 2 Hz and 0.4-1.0 V and regular pulsation of the patient's muscle of occiput could occur. Pulsed radiofrequency was applied at 42 ℃7 for 240 s and was performed twice on each side. VAS scores and disturbances of daily activity, mood and sleep were recorded before operation and at 1 week and 1, 3, 6, 12 and 18 months after pulsed radiofrequency treatment. Complications and recurrence within 12 and 18 months were recorded. Follow-up was lost in 22 patients. VAS scores and disturbances of daily activity, mood and sleep significantly decreased after procedure. All of the patients responded without complications like infection, spinal cord and vertebral artery injury. Some patients had transient occipital neuralgia which was usually relieved within 24 h. The recurrence rate in 12 and 18 months after operation was 19% and 31% respectively.
ABSTRACT
From November 2003 to May 2010, intrathecal drug delivery system (IDDS) was implanted in 18 patients with chronic intractable pain. Analgesia was provided with morphine. Thirteen patients suffered from late stage cancer and 5 from diseases other than cancer. VAS score was used to measure intensity of pain in all 18patients. QLQ-C30 score was used to evaluate quality of life in cancer patients. The patients were followed up for 3-62 months in 5 non-cancer patients. All 13 cancer patients died at 57 days-10 months after operation. VAS scores were significantly decreased and QLQ-C30 scores increased by intrathecal administration of morphine. Side effects developed in all patients to some extent including nausea, vomiting, constipation, urinary retention, pruritus and over-sedation and vanished in a week. Intrathecal catheter was cut while being pulled out of the needle in 1 patient. Two patients developed low intracranial pressure after operation. Cerebrospinal fluid leakage occurred in 1 patient. One patient developed neuropathic pain in the posterolateral side of right leg.
ABSTRACT
Objective To compare the biomechanical properties of mono-segTnent pedicle instru-mentation and its combination with bone cement fixation in treatment of thoracolumbar fractures. Meth-ods Eight fresh specimens of calf spines ( T11 -L3 ) were used for development of incomplete burst frac-ture models at the vertebral body of L1. Mono-segment pedicle instrumentation and its combination with vertebroplasty were respectively applied in each specimen subsequently to restore spinal stability. A cyclic loading with pure moment of 4 Nm was applied to specimens, with load frequency of 0.5 Hz for 2 000 cy-cles. Range of motion (ROM) at flexion/extension, left/right lateral bending and left/right axial rotation of the fixated segment at different status of intact, injury, fixation and cyclic loading was determined by spinal three-dimensional instability test system. Results ROM after treatment with two fixation tech-niques and that at different directions after cyclic loading were distinctly smaller than that of intact and fractured models (P <0.05 ). Under mono-segment pedicle instrumentation combined with bone cement fixation, ROM at flexion, extension, lateral bending and axial rotation was 0.40°, 0. 53°, 0.86° and 0.55° respectively and that after cyclic loading was 0.10°, 0.07°, 0.19° and 0.08°respectively, which were all lower than those of monosegmental fixation, especially at flexion and axial rotation, with statisti-cal difference (P <0.05 ). Conclusions Both fixation techniques can provide instant stabihty of the fractured spine and have good fatigue resistance effect. However, mono-segment pedicle instrumentation is inferior to mono-segment pedicle instrumentation plus bone cement fixation in treatment of fractured verte-bral body at flexion and axial rotation.
