B-cell maturation antigen (BCMA) is expressed on malignant plasma cells from patients with multiple myeloma (MM). These patients have higher levels of serum (s)BCMA than healthy subjects, and levels correlate with disease status. The half-life of sBCMA is only 24-36 h, and levels are independent of renal function.

We determined whether baseline sBCMA values, a ≥ 25% increase, and a ≥ 50% decrease during treatment predicted progression-free survival (PFS) and overall survival (OS) among 81 patients with relapsed/refractory MM (RRMM) starting new treatments.

Serum was obtained on day 22 of each patient's 28-day cycle of new therapy. Kaplan-Meier survival analysis and log-rank comparison tests were used to determine the effect of baseline sBCMA. The effect of percentage change in sBCMA was investigated using time-dependent Cox proportional hazard models.

Patients with baseline sBCMA levels above the median had a shorter PFS (p=0.0077), and those in the highest quartile had a shorter PFS (p = 0.0012) and OS (p=0.0022). A ≥ 25% increase at week 4, week 8, and anytime through week 12 predicted a shorter PFS (p = 0.0011, p = 0.0005, and p < 0.0001, respectively). A ≥ 50% decrease at week 4, week 8, and anytime through week 12 predicted a longer PFS (p = 0.0045, p = 0.029, p = 0.0055, respectively). A ≥ 25% increase in sBCMA occurred before progression according to International Myeloma Working Group criteria in 67.5% of patients.

Our results indicate the potential for the use of sBCMA as a new biomarker for monitoring patients with RRMM.

To verify this hypothesis, we determined the effect of CAFs on Na+,K+-ATPase tubulin-dependent activity in COS cells, ex vivo cataract formation in rat lenses and finally, to evaluate the antidiabetic effect of CAFs, diabetes mellitus was induced in Wistar rats, they were treated with different CAFs and four parameters were determinates cataract formation, erythrocyte deformability, nephropathy and blood pressure. After confirming that CAFs are able to prevent the association between aldose reductase and tubulin, we found that treatment of diabetic rats with these compounds decreased membrane-associated acetylated tubulin, increased NKA activity, and thus reversed the development of four AR-activated complications of diabetes mellitus determined in this work. Based on these results, the existence of a new physiological mechanism is proposed, in which tubulin is a key regulator of aldose reductase activity. This mechanism can explain the incorrect functioning of aldose reductase and Na+,K+-ATPase, two key enzymes in the pathogenesis of diabetes mellitus. Moreover, we found that such alterations can be prevented by CAFs, which are able to dissociate tubulin/aldose reductase complex.

To quantify the associations between the under-five mortality rate (U5MR) and measures of pediatric human resources, including pediatricians per thousand children (PPTC) and the geographical distribution of pediatricians.

We analyzed data from a national survey in 2015-2016 in 2636 counties, accounting for 31 mainland provinces of China. We evaluated the associations between measures of pediatric human resources and the risk of a high U5MR (≥ 18 deaths per 1000 live births) using logistic regression and restricted cubic spline regression models with adjustments for potential confounders. PPTC and pediatricians per 10,000 km

were categorized into quartiles. The highest quartiles were used as reference.

The median values of PPTC and pediatricians per 10,000 km

were 0.35 (0.20-0.70) and 150 (50-500), respectively. Compared to the counties with the highest PPTC (≥ 0.7), those with the lowest PPTC (< 0.2) had a 52% higher risk of a high U5MR, with an L-shaped relationship. An inverted J-shaped relationship was found that the risk of a high U5MR was 3.74 [95% confidence interval (CI) 2.55-5.48], 3.07 (95% CI 2.11-4.47), and 2.25 times (95% CI 1.52-3.31) higher in counties with < 50, 50-149, and 150-499 pediatricians per 10,000 km

, respectively, than in counties with ≥ 500 physicians per 10,000 km

. The joint association analyses show a stronger association with the risk of a high U5MR in geographical pediatrician density than PPTC.

Both population and geographical pediatrician density should be considered when planning child health care services, even in areas with high numbers of PPTC.

About one-third of them have comorbid diabetes mellitus type 2. Until recently, the effects of antidiabetic agents on heart failure were largely unknown. This changed after an observed increased risk of heart failure and ischaemic heart disease associated with thiazolidinediones that prompted the requirement for cardiovascular outcome trials for new glucose-lowering drugs. In the past decade, three new classes of antidiabetic agents have become available (i.e. dipeptidyl peptidase‑4 inhibitors, glucagon-like peptide‑1 receptor agonists and sodium-glucose cotransporter‑2 (SGLT2) inhibitors). Although the first two classes demonstrated no beneficial effects on heart failure compared to placebo in patients with diabetes mellitus type 2, SGLT2 inhibitors significantly and consistently lowered the risk of incident and worsening heart failure. Two recent trials indicated that these favourable effects were also present in non-diabetic patients with heart failure with reduced ejection fraction, resulting in significantly lower risks of hospitalisation for heart failure and presumably also cardiovascular and all-cause mortality. Inflammation inhibitor SGLT2 inhibitors have been shown to be benefit on top of recommended heart failure therapy including sacubitril/valsartan and may also prove beneficial for heart failure with preserved ejection fraction. In this review, we discuss the effects of antidiabetic agents on heart failure.
