Objective:To investigate the influence of hypomagnesemia on the prognosis of patients with severe sepsis.Methods:A retrospective study was conducted. The clinical data of 207 septic patients admitted to the department of critical care medicine of the First Affiliated Hospital of University of Science and Technology of China from January 1, 2016 to December 21, 2020 were analyzed, including gender, age and laboratory indicators within 24 hours after sepsis diagnosis [procalcitonin (PCT), C-reactive protein (CRP), blood lactic acid (Lac), pH value and blood magnesium, calcium, chlorine and phosphorus levels]. The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score and 28-day prognosis were collected. The patients were divided into survival group and non-survival group according to the prognosis, and the clinical data and laboratory indexes were compared between the two groups. Pearson correlation test was used to analyze the correlation between clinical indicators. Multivariate Logistic regression analysis was used to screen the risk factors affecting the prognosis. The receiver operator characteristic curve (ROC curve) was drawn, and the area under ROC curve (AUC) was calculated to evaluate the potential prognostic indicators.Results:Among the 207 septic patients, 102 survived and 105 died on the 28th day, and the 28-day mortality was 50.72%. There were no significant differences in gender, age, CRP, pH value, blood chlorine or blood phosphorus levels between the two groups. The blood magnesium and blood calcium levels in the non-survival group were significantly lower than those in the survival group [blood magnesium (mmol/L): 0.68±0.14 vs. 0.80±0.12, blood calcium (mmol/L): 1.93±0.21 vs. 2.01±0.20, both P < 0.01], and PCT, Lac, APACHE Ⅱ score and SOFA score were significantly higher than those in the survival group [PCT (mg/L): 8.32 (1.64, 55.01) vs. 3.55 (0.97, 12.31), Lac (mmol/L): 2.90 (1.70, 4.30) vs. 2.10 (1.03, 3.89), APACHE Ⅱ score: 21.24±6.40 vs. 17.42±7.02, SOFA score: 9.14±3.55 vs. 6.91±3.31, all P < 0.01]. Among the 207 patients, 96 patients had normal blood magnesium level (0.75-1.25 mmol/L) and 111 patients had hypomagnesemia (< 0.75 mmol/L). The 28-day mortality of septic patients in the hypomagnesemia group was significantly higher than that in the normal magnesium group [61.26% (68/111) vs. 38.54% (37/96), P < 0.01]. Pearson correlation analysis showed that the blood magnesium level of sepsis patients was negatively correlated with PCT ( r = -0.173, P < 0.05), and it was positively correlated with APACHE Ⅱ score ( r = 0.159, P < 0.05), but it had no correlation with CRP or SOFA score ( r values were -0.029 and 0.091, both P > 0.05). Logistic regression analysis showed that serum magnesium, APACHE Ⅱ score and SOFA score were independent risk factors for 28-day death in patients with sepsis [serum magnesium: odds ratio ( OR) < 0.001, 95% confidence interval (95% CI) was 0.000-0.002, P < 0.001; APACHE Ⅱ score: OR = 1.092, 95% CI was 1.022-1.168, P = 0.010; SOFA score: OR = 1.168, 95% CI was 1.026-1.330, P = 0.019]. ROC curve analysis showed that blood magnesium and APACHE Ⅱ score had a certain predictive value for 28-day mortality in patients with severe sepsis [AUC (95% CI) was 0.723 (0.655-0.791) and 0.680 (0.607-0.754), respectively]. When the blood magnesium threshold was 0.64 mmol/L, the sensitivity was 41.0% and the specificity was 93.1%. When APACHE Ⅱ score threshold was 16.50, the sensitivity was 78.1% and the specificity was 55.9% indicating that the specificity of serum magnesium was higher than that of APACHE Ⅱ score. Conclusions:Severe septic patients complicated with hypomagnesemia have a poor prognosis. Serum magnesium level can be used as a prognostic indicator for severe septic patients.

Objective:To investigate the clinical characteristics of gastrointestinal symptoms in patients with coronavirus disease 2019 (COVID-19) during the whole disease process, and provide reference for etiological diagnosis and treatment.Methods:The clinical data of patients with COVID-19 admitted in the Infectious Diseases Branch of the First Affiliated Hospital of University of Science and Technology of China from January 22nd, 2020 to March 8th, 2020 were analyzed retrospectively. According to whether there were gastrointestinal symptoms (poor appetite, nausea/vomiting and diarrhea), all patients were divided into gastrointestinal symptom group and asymptomatic group. The characteristics of gastrointestinal symptoms, such as poor appetite, nausea, vomiting and diarrhea were counted and analyzed, and the correlation between gastrointestinal symptoms and gender, age, basic diseases, disease severity, laboratory examination and drug treatment were analyzed.Results:A total of 80 COVID-19 patients were involved, 43 cases (53.8%) presented with poor appetite, 17 cases (21.3%) had nausea and vomiting, and 33 cases (41.3%) had diarrhea. Among them, 5 cases, 1 case and 4 cases respectively preformed poor appetite, nausea/vomiting and diarrhea before admission, while the others experienced gastrointestinal symptoms within 48 hours after admission. Duration of poor appetite, nausea/vomiting and diarrhea (days) of all patients were 5.3±2.1, 2.2±1.0 and 1.4±0.9, respectively. The patients with poor appetite were older than those without symptoms (years old: 48.2±17.6 vs. 39.3±15.1), albumin (Alb) level and the lymphocytes ratio were lower than those in asymptomatic group [Alb (g/L): 39.8 (35.7, 45.1) vs. 46.1 (42.6, 49.4), lymphocytes ratio: 0.19 (0.09, 0.28) vs. 0.28 (0.17, 0.35)], while the neutrophil ratio, the levels of C-reactive protein (CRP), D-dimer, and lactate dehydrogenase (LDH) were higher than those in asymptomatic group [the neutrophil ratio: 0.74 (0.61, 0.85) vs. 0.64 (0.52, 0.76), CRP (mg/L): 21.4 (3.9, 52.9) vs. 5.6 (2.4, 14.0), D-dimer (mg/L): 0.2 (0.2, 0.5) vs. 0.2 (0.1, 0.3), LDH (μmol·s -1·L -1): 4.49 (3.59, 5.19) vs. 3.12 (2.77, 4.90)]; at the same time, more traditional Chinese medicine was used in the patients with gastrointestinal symptoms [65.1% (28/43) vs. 40.5% (15/37), all P < 0.05]. In addition, 14 cases of 18 patients with cardiovascular diseases presented with poor appetite, 7 patients had nausea and vomiting symptoms. All of the 3 patients with chronic kidney disease presented with poor appetite, nausea and vomiting, and 2 of them had diarrhea. Conclusions:The gastrointestinal symptoms in patients with COVID-19 are common. Whether it is caused by the virus or related drugs, diet and mental conditions, clinicians should analyze the causes of these symptoms timely, and then provide a better treatment for patients with COVID-19.

Acute respiratory failure due to acute hypoxemia is the major manifestation in severe coronavirus disease 2019 (COVID-19). Rational and effective respiratory support is crucial in the management of COVID-19 patients. High-flow nasal cannula (HFNC) has been utilized widely due to its superiority over other non-invasive respiratory support techniques. To avoid HFNC failure and intubation delay, the key issues are proper patients, timely application and improving compliance. It should be noted that elder patients are vulnerable for failed HFNC. We applied HFNC for oxygen therapy in severe and critical ill COVID-19 patients and summarized the following experiences. Firstly, to select the proper size of nasal catheter, to locate it at suitable place, and to confirm the nose and the upper respiratory airway unobstructed. Secondly, an initial ow of 60 L/min and 37℃ should be given immediately for patients with obvious respiratory distress or weak cough ability; otherwise, low-level support should be given first and the level gradually increased. Thirdly, to avoid hypoxia or hypoxemia, the treatment goal of HFNC should be maintained the oxygen saturation (SpO) above 95% for patients without chronic pulmonary disease. Finally, patients should wear a surgical mask during HFNC treatment to reduce the risk of virus transmission through droplets or aerosols.
