ABSTRACT
Objective:To explore the correlation between blood glucose levels and the three factors of sarcopenia (muscle mass, strength and function) in older Chinese community dwellers.Methods:This is a retrospective study conducted by collecting the data of patients in Jiangsu Huaqiao Road Community Health Service Center from 2018 to 2019. Two hundred and fifty people aged 60 years or elder were selected. Among them, 101 were men and 149 were women. According to the American Diabetes Association diagnostic criteria for diabetes mellitus in 2018, they were divided into normal glucose tolerance (NGT) group, pre-diabetes group and diabetes group. The patients were assessed for sarcopenia as well.Results:Compared with those in the NGT group, muscle mass and upper limb muscle strength did not change in the diabetic group, but lower limb muscle strength and body function [walking speed, balance, short physical performance battery (SPPB)] decreased significantly in the diabetic group. Pearson correlation analyses showed that fasting plasma glucose(FPG) was negatively correlated with walking speed ( r=-0.248, P=0.001), three-pose balance ( r=-0.166, P=0.013) and SSPB ( r=-0.213, P=0.001). Glycosylated hemoglobin A1c(HbA1c) was positively correlated with sitting and standing time ( r=0.205, P=0.002), and negatively correlated with three-pose balance ( r=-0.186, P=0.006) and SSPB ( r=-0.154, P=0.024). Multiple regression analyses showed that FPG was negatively associated with walking speed (β=-0.125, P=0.005) and SPPB (β=-0.034, P=0.012), and that HbA1c was positively associated with sitting and standing time (β= 0.218, P =0.006) and negatively associated with three-pose balance (β=-0.143, P=0.012), and SPPB (β=-0.117, P =0.036). Conclusions:There is no significant correlation between blood glucose levels and muscle mass in the elderly; however, FPG is closely correlated with gait speed, and HbA1c is closely correlated with muscle strength of lower limbs and balance ability in the elderly.
ABSTRACT
To explore the effect of proton pump inhibitors (PPI) on the micro-structure of bone in older men. A retrospective study was conducted on data of patients over the age of 60 who were admitted to the Geriatric Department of Jiangsu People′s Hospital from June 2018 to January 2019. Patients were divided into control group (taking PPI for less than 1 week, 50 cases) and PPI treatment group (taking PPI for more than 3 months, 30 cases). Biochemical indexes, bone mineral density (BMD)and trabecular bone score (TBS) were analyzed. Compared with control group, the weight and albumin level in the PPI treatment group were lower, and the thyrotropin level was higher ( P<0.05). There was no statistical difference in the BMD of femur or lumbar vertebrae between the two groups ( P>0.05), but the TBS of lumbar vertebrae in the PPI treatment group was significantly decreased ( P<0.05). Correlation analysis found that TBS was positively correlated with alkaline phosphatase (ALP) ( r=0.45, P=0.002) and body mass index ( r=0.164, P=0.045), and negatively correlated with age ( r=-0.291, P=0.025). Multiple linear regression model analysis showed that there was still a positive correlation between TBS and ALP ( β=0.437, P=0.023). In the elderly men, the use of PPI for more than 3 months can significantly affect the bone micro-structure, and the bone micro-structure can better reflect the adverse effect of PPI on bone than BMD.
ABSTRACT
Objective:To study on the association between vasoactive-inotropic score(VIS) and mortality of total arch replacement in Stanford type A aortic dissection(TAAD) patients.Methods:Data of TAAD patients admitted from January 2018 to November 2018 were analyzed retrospectively. According to the inclusion and exclusion criteria, 187 patients were finally included in the analysis. 30-day mortality was calculated and the patients were divided into death group(18 cases) and non-death group(169 cases). The VIS at each time point and perioperative indexes of the two groups were compared. The value of VIS in predicting mortality was analyzed.Results:The 30-day mortality was 9.63%(18/187). The operation time, cardiopulmonary bypass time, ventilator assistance time, the incidence of tracheotomy and major postoperative complications in the death group were significantly higher than those in the non-death group( P<0.05). VIS of death group was significantly higher than that of non-death group( P<0.05). At each time point, the area under ROC curve(AUC) of VIS was greater than 0.500( P<0.05), among which AUC of ICU 48 h VIS was the largest(0.817), and the best cut-off point of ICU 48 h VIS was determined to be 9, sensitivity 61.1%, specificity 92.3%. Logistic regression analysis showed that ICU 48 h VIS was an independent risk factor for predicting the death of total arch replacement in TAAD patients( OR=1.465, 95% CI: 1.194-1.796, P<0.001). Conclusion:When ICU 48 h VIS≥9, the risk of death was increased in patients with total arch replacement of TAAD. VIS may be a useful reference index for predicting the mortality of total arch replacement in TAAD patients in the early postoperative period.
ABSTRACT
Objective:To explore the prevalence and risk factors of exit-site infection (ESI) in elderly peritoneal dialysis (PD) patients.Methods:The status of exit-site was evaluated in elderly PD patients (≥60 years) who had catheter insertion in our center between January 1, 2009 and December 31, 2013, with follow-up for 1 year or withdrawing from peritoneal dialysis in this period. The patients were divided into ESI and non-ESI group. The data was collected including demographics, clinical features, and nursing care methods of the exit-site.Results:A total of 247 patients were recruited in this study, aged (68.6±6.2) years, among whom there were 132 male (53.4%) and 119 diabetes (48.2%). Median follow-up time was 12.0 months. Thirty-two patients had 34 episodes of ESI with a rate of 82.5 patient-months per episode (0.15 episodes per year). Coagulase-negative Staphylococcus was the main pathogen, accounting for 35.3% of the ESI. No bacterial growth was found in 8.8%. The exit-site nursing care status included that poor compliance of exit-site care 23.5%, poor catheter immobilization 62.3%, history of catheter-pulling injury 9.7%, mechanical stress on exit-site 5.3%, improper frequency of nursing care 29.6%, mupirocin usage 13.8%, patients taking exit-site care 26.7%, exit-site caregiver instability 16.6%. There were no differences in demographic (such as age, gender, primary disease, etc) and laboratory data (hemoglobin, serum albumin, blood potassium, etc) between the ESI and non-ESI groups. Poor compliance with exit-site care ( HR=2.352, 95% CI 1.008-5.488, P=0.048), poor catheter immobilization ( HR=3.074, 95% CI 1.046-9.035, P=0.041) and exit-site caregiver instability ( HR=2.423, 95% CI 1.004-5.845, P=0.049) were significantly correlated with increased risk of ESI. Conclusions:The prevalence of ESI in elderly PD patients was 0.15 episodes per year. Educating PD patients to improve the compliance with exit-site care, maintain catheter immobilization and do exit-site care by a stable and trained caregiver may reduce ESI events in elderly PD patients.
ABSTRACT
Objective To analyze the cerebral autoregulation capability in patients with chronic insomnia disorder (CID).Methods Sixty CID patients (54 with generalized anxiety disorder) and 40 healthy controls were enrolled in this study.Polysomnography was done in all the participants.Noninvasive continuous cerebral blood flow velocity of bilateral middle artery and arterial blood pressure were recorded simultaneously using transcranial Doppler and a servo-controlled plethysmograph.Transfer function analysis was used to derive the autoregulatory parameters, including phase difference and coherence function.Results The phase difference values of CID patients with generalized anxiety disorder were significantly lower than that of the healthy controls ((46.89±15.39)°vs (56.00±12.05)°, t=3.439, P=0.001).In the correlation analysis, we further found that there was no correlation among phase difference values and the score of Hospital Anxiety and Depression scale.Conclusions The dynamic cerebral autoregulation was compromised in CID patients with generalized anxiety disorder regardless of the degrees of anxiety and depression.Dynamic cerebral autoregulation may be a potential therapeutic target in improving neurological symptoms in patients with CID.
ABSTRACT
Actively heated, humidified high flow nasal cannula oxygen therapy (HFNC) is a new type of oxygen therapy. Because of its unique physiological effects, the clinical application is becoming more and more popular. This article is to summarize the physiological effects, clinical application and short comings of HFNC. Compared with conventional oxygen therapy, HFNC helps to improve oxygenation better, and it is more comfortable than non-invasive ventilation (NIV) in use. Proper use of HFNC may be able to reduce the use of NIV and decrease the rate of endotracheal intubation. It can be used for adults with mild to moderate hypoxia, or for patients undergoing palliative care. However, the experience of the use of HFNC in adults is limited, and there is yet no corresponding clinical guideline. Therefore, further research with a large sample is required to determine the long-term effect of this technique, and to identify the adult patient population to whom is most beneficial.

ABSTRACT
<p><b>OBJECTIVE</b>To summarize the clinical manifestation and diagnosis of ganglioneuroma in spine and investigate the clinical effect of surgical treatment.</p><p><b>METHODS</b>The clinical data of 6 patients underwent a surgery for ganglioneuroma in spine from January 2008 to January 2015 were retrospectively analyzed. There were 4 males and 2 females, aged from 2 to 63 years old with an average of 34.6 years. The courses of disease were from 3 days to 17 years. Five patients complicated with superficial hypesthesia in correlative level of tumor, and the muscle strength under tumor plane had decreased at different levels, with the strength of grade II-IV. Two cases complicated with hypermyotonia and positive bilateral Hoffmann's and Babinski sign. Five cases were sporadic lesion in correlative spinal canal and one case complicated with the giant occupying lesion in thoracic cavity.</p><p><b>RESULTS</b>Six operations had been performed including 5 en bloc and 1 subtotal resection. Postoperative pathological results showed tumor cells scattered or fasciculated inserted into Schwann cells in the stroma. In 2 patients complicated with radiculalgia before operation, 1 case was relieved and 1 was invariant after operation. All 4 patients with preoperative dyscinesia in the limbs obtained improvement after operation. All the patients were followed up from 0.3 to 6.8 years with an average of 2.5 years. At the final follow-up, according to ASIA grade, 5 cases were good and 1 case was invariant. During the follow-up, only 1 patient experienced chemoradiation because of merging ganglioneuroblastoma and receiving subtotal resection. No recurrence in other 5 cases.</p><p><b>CONCLUSION</b>Ganglioneuroma is a benign and rare tumors in spine. Clinically, radicular pain and sensory-motor disorders are the main manifestations. Its diagnosis depends on pathological examination. Prognosis of surgical treatment is good.</p>
