Abstract
BACKGROUND Results from both clinical trials and real-world observational studies suggest that lamivudine plus dolutegravir (3TC + DTG) dual therapy has excellent virological efficacy and safety in HIV-1-infected patients. However, there is still no relevant study related to this dual therapy reported in China. METHODS In this multicenter, retrospective, observational study that included HIV-1-infected patients in China, baseline and follow-up data were collected to analyze the virological suppression rate, immune restoration, and adverse events during follow-up in HIV-1-infected patients who switched to the 3TC + DTG dual therapy. RESULTS This study recruited 112 HIV-1-infected patients, including 101 men (90.2%), with a median age of 44.0 years (IQR: 33.00-57.75) and median CD4+ T-cell count of 432.13 cells/μL (IQR: 237.75-578.50). The overall virological suppression rate was 94.5% at the 24-week follow-up. However, the virological suppression rates of men who have sex with men patients and patients with CD4+ T-cell count of <350 cells/μL were higher than the baseline value (P < 0.05) at week 24. The results of Cox regression analysis showed that the baseline CD4+ T-cell count was an independent determinant of immune restoration in patients, and patients with baseline CD4+ T-cell count of 350-500 cells/μL outperformed patients with baseline CD4+ T-cell count of <350 cells/μL in immune restoration (hazard ratio: 4.469, 95% confidence interval: 1.801 to 11.091, P = 0.001). Adverse events were reported in 5 patients (incidence rate of 4.5%); among them, 3 patients developed neuropsychiatric symptoms. Results from the laboratory data analysis showed that patients with grade 1 and 2 adverse events had elevated levels of low-density lipoprotein cholesterol and total bilirubin. Furthermore, grade 3 and 4 adverse events were associated with the elevation of blood glucose level in 4 patients. CONCLUSIONS Thus, the 3TC + DTG dual therapy displayed an excellent virological efficacy against HIV-1 infections and had an acceptable safety profile, with predominantly mild adverse events in HIV-1-infected patients in China.

Plain language summary
Hyperglycaemia was a risk factor for mortality from severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) and is an independent risk factor for lower respiratory tract infection and poor prognosis. The aim of this retrospective study of 605 patients without previously diagnosed diabetes was to examine the association between fasting blood glucose (FBG) on admission and the 28-day in hospital mortality of COVID-19 patients. Patients with a FBG level of 7.0mmol/l or over had more than double the risk of dying than those with a level of 6.0mmol/l or less. Other risk factors for mortality included age, being male, and severity of pneumonia at admission. Compared with patients whose FBG was 6.0mmol/l or lower at admission, patients with FBG of 7.0 mmol/l and above had a 3.99 times higher risk of in-hospital complications, whilst those with FBG of 6.1–6.9 mmol/l had a 2.61 times higher risk of complications. The authors conclude that glycaemic testing and control are important to all COVID-19 patients even where they have no pre-existing diabetes.
Abstract
AIMS/HYPOTHESIS Hyperglycaemia is associated with an elevated risk of mortality in community-acquired pneumonia, stroke, acute myocardial infarction, trauma and surgery, among other conditions. In this study, we examined the relationship between fasting blood glucose (FBG) and 28-day mortality in coronavirus disease 2019 (COVID-19) patients not previously diagnosed as having diabetes. METHODS We conducted a retrospective study involving all consecutive COVID-19 patients with a definitive 28-day outcome and FBG measurement at admission from 24 January 2020 to 10 February 2020 in two hospitals based in Wuhan, China. Demographic and clinical data, 28-day outcomes, in-hospital complications and CRB-65 scores of COVID-19 patients in the two hospitals were analysed. CRB-65 is an effective measure for assessing the severity of pneumonia and is based on four indicators, i.e. confusion, respiratory rate (>30/min), systolic blood pressure (≤90 mmHg) or diastolic blood pressure (≤60 mmHg), and age (≥65 years). RESULTS Six hundred and five COVID-19 patients were enrolled, including 114 who died in hospital. Multivariable Cox regression analysis showed that age (HR 1.02 [95% CI 1.00, 1.04]), male sex (HR 1.75 [95% CI 1.17, 2.60]), CRB-65 score 1-2 (HR 2.68 [95% CI 1.56, 4.59]), CRB-65 score 3-4 (HR 5.25 [95% CI 2.05, 13.43]) and FBG ≥7.0 mmol/l (HR 2.30 [95% CI 1.49, 3.55]) were independent predictors for 28-day mortality. The OR for 28-day in-hospital complications in those with FBG ≥7.0 mmol/l and 6.1-6.9 mmol/l vs <6.1 mmol/l was 3.99 (95% CI 2.71, 5.88) or 2.61 (95% CI 1.64, 4.41), respectively. CONCLUSIONS/INTERPRETATION FBG ≥7.0 mmol/l at admission is an independent predictor for 28-day mortality in patients with COVID-19 without previous diagnosis of diabetes. Glycaemic testing and control are important to all COVID-19 patients even where they have no pre-existing diabetes, as most COVID-19 patients are prone to glucose metabolic disorders.

Abstract
OBJECTIVES Sorafenib is a multi-tyrosine kinase inhibitor of Raf kinase, VEGFR, and PDGFR. Angiogenesis is important for growth and progression of SCLC. This trial was conducted to evaluate whether the combination of cisplatin and etoposide plus concurrent and sequential sorafenib could prolong survival in patients with previously untreated SCLC. METHODS Previously untreated patients with extensive stage SCLC were treated with cisplatin and etoposide days 1, 2, 3 for four cycles, concurrent with sorafenib 200 mg orally bid starting day 1 cycle 1. Patients with no disease progression after four cycles continued sorafenib 400 mg orally bid as maintenance for maximum of 12 months. The primary endpoint was 1 year survival with response rate and safety as secondary endpoints. RESULTS A total of 18 patients were enrolled with 17 evaluable patients. One patient had a complete response, seven patients had a partial response (overall response rate of 47 %) and one patient had stable disease. Overall median survival was 7.4 months and 1 year survival was 25 %. The most common treatment-related adverse events included fatigue, anorexia, rash, diarrhea, neutropenia and weight loss. Grade 5 GI bleeding, pulmonary hemorrhage and neutropenia occurred in one pt (6 %) each. Accrual was halted on the basis of safety profile as well as preliminary efficacy data. CONCLUSIONS The combination of platinum based chemotherapy and sorafenib has significant toxicity at current dose levels and is associated with disappointing efficacy data.

Abstract
BACKGROUND Mibefradil is a T-type calcium-channel antagonist and arterial vasodilator with negative chronotropic effects. It is not known if T-type calcium-channel blockade is superior to L-type calcium-channel blockade in patients with stable angina pectoris. METHODS A multicenter, randomized, double-blind trial was conducted in patients with documented coronary disease and stable angina to compare a 360 mg dose of diltiazem CD with 100 mg dose of mibefradil. The primary end point was change in time to symptom-limited exercise termination from baseline to 8 weeks. Secondary efficacy parameters included time to onset of persistent ST-segment depression, time to awareness of angina, and change in exercise duration from baseline to 2 and 4 weeks of treatment. RESULTS A total of 121 patients were randomized to mibefradil and 113 to diltiazem CD. At 8 weeks, the increase in exercise duration was 24.5 seconds greater in the mibefradil group (P =.017; 95% CI 4.4-44.7 seconds). At 8 weeks, time to development of > or =1 mm ST-segment depression was greater by 45.3 seconds (P =.0025; 95% CI 16.2-74.5) with mibefradil, but time to development of angina was not significantly different. CONCLUSION T-type calcium-channel antagonism with mibefradil improved treadmill exercise parameters compared with diltiazem in patients with chronic stable angina. Further investigation and development of antagonists of T-type calcium channels with fewer adverse drug interactions is warranted and may be promising in the management of ischemic heart disease.
