Kidney denervation: will we media the "ON" button yet again in 2020?
Narirutin can also suppress the phosphorylation of MAPK signaling pathways by decreasing the expression of P-p38, P-ERK and P-JNK, inhibit the synergistic effect for Ca2+ influx, and then reduce the release of IL-4, TNF-α, histamine and β-HEX. Conclusion Our study suggested that the inhibitory mechanism of narirutin on RBL-2H3 cells degranulation could be related to regulate MAPK, NF-κB and Tyrosine kinase signaling pathway.This randomized double-blind controlled study aimed to investigate the effects of a standardized Kaempferia parviflora (KP) extract on the physical fitness and heart rate variability (HRV) parameters in adolescent sport school students. 194 male students were recruited and randomized into two groups (n = 97), matched by age and sports. The KP-treated group received KP extract capsules at a dose of 360 mg/day and the control group received placebo capsules, continuously for 12 weeks. Physical fitness performance and HRV parameters were monitored with blood biochemical analysis for product safety. KP extract significantly increased the right-hand grip strength, the back-leg strength and maximal oxygen consumption (VO2 max) and decreased the time used for 50-meter sprint test without changing the sit-and-reach test and the 40 yard technical test. For HRV parameters, KP extract significantly increased standard deviation of normal to normal intervals (SDNN), square root of the mean of square of successive normal to normal interval differences (RMSSD) and high frequency (HF) norm, without changing low frequency (LF) norm and LF/HF ratio. The increase in stress resistance and decrease in stress index were found in the KP-treated group, without changing the autonomic nervous system (ANS) activity and balance. Blood biochemical analysis showed normal values of all participants. This data indicates the safety and positive effects of KP on muscle strength, endurance and speed, but not on the flexibility and agility. The modulatory effects of KP extract on HRV parameters suggest its anti-stress effects and would encourage the application in a sport training and exercise.
Meta-analysis.

To provide up-to-date evidence-based outcomes for the incidence and risk factors of adjacent vertebral fracture (AVF) after the vertebral augmentation.

The MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched for studies assessing the risk factors of adjacent vertebral fracture after vertebral augmentation until June 2020. The AVF incidence and factors potentially affecting AVF were extracted and pooled.

A total of 16 studies, encompassing 2549 patients were included in the meta-analysis. The pooled incidence of AVF was 14% after vertebral augmentation. Female, lower T-score, thoracolumbar junction fracture, intravertebral cleft, more injected cement volume, intradiscal cement leakage significantly increased the risk of AVF. FHD-609 Age, body mass index, steroid medication, Cobb angle change, postoperative Cobb angle showed no significant association with AVF.

Identifying the risk factors of AVF can facilitate prevention strategy to avoid the AVF. Female, T-score, thoracolumbar junction fracture, intravertebral cleft, more cement volume, and intradiscal cement leakage increased the risk of AVF.

Patient-reported outcome measures are an increasingly important tool for assessing the impact of treatments orthopedic surgeons render. Despite their importance, they can present a burden. We examined the validity and utility of a computerized adaptive testing (CAT) method to reduce the number of questions on the Foot and Ankle Ability Measure (FAAM), a validated anatomy-specific outcome measure.

A previously developed FAAM CAT system was applied to the responses of patients undergoing foot and ankle evaluation and treatment over a 3-year period (2017-2019). A total of 15 902 responses for the Activities of Daily Living (ADL) subscale and a total of 14 344 responses for the Sports subscale were analyzed. The accuracy of the CAT to replicate the full-form score was assessed.

The CAT system required 11 questions to be answered for the ADL subscale in 85.1% of cases (range, 11-12). The number of questions answered on the Sports subscale was 6 (range, 5-6) in 66.4% of cases. The mean difference between the full FAAM ADL subscale and CAT was 0.63 of a point. The mean difference between the FAAM Sports subscale and CAT was 0.65 of a point.

The FAAM CAT was able to reduce the number of responses a patient would need to answer by nearly 50%, while still providing a valid outcome score. This measure can therefore be directly correlated with previously obtained full FAAM scores in addition to providing a foot/ankle-specific measure, which previously reported CAT systems are not able to do.

The degree and severity of dark circles varies according to the skin type, age, and lifestyle.

To evaluate different non-surgical treatment options for dark circles.

In a private practice setting in the UK and India, 34 patients with dark circles with different Fitzpatrick skin types were treated with fillers (Group 1), lasers (Group 2), and fillers and lasers combined (Group 3). Pre and post treatment photos were taken and subjective and objective outcomes in appearance were reported.

All treatment options were effective in all three groups with minimal side effects reported. No statistically significant difference was found between the three treatment groups. Patients who had tear troughs and/or hollow eyes responded well to fillers, patients with loose and wrinkled skin to CO
laser, patients with tear troughs and hyperpigmentation to fillers, Q switched NdYAG and topical agents and patients with tear troughs and veins to fillers and long pulsed NdYAG lasers. Most patients (82%) rated the improvement in their appearance as excellent.

All 3 treatment modalities were effective in the reduction of periorbital dark circles depending on underlying cause. Non-surgical treatments are capable of correcting and improving dark circles with minimum complications and downtime.
