Comparative effectiveness of neuraminidase inhibitors in patients with influenza: A systematic review and network meta-analysis.

The aim of this study was to use a network meta-analysis (NWA) to evaluate the relative efficacy and safety of various neuraminidase inhibitors (NAIs) in reducing the duration of influenza symptoms, and thereby, informing the selection of suitable therapeutic regimens for patients with influenza. We conducted a systematic review of randomized controlled trials comparing the clinical effects of four NAIs administered to patients with influenza and placebo. Relevant studies were found in the PubMed and Cochrane databases. Unpublished studies were collected from the ClinicalTrials.gov registry and through hand searching. We carried out NWA to compare the different regimens with each other and across subgroups of age and medical status (high-risk patients). A total of 58 two-arm studies were identified. Five regimens were efficacious in reducing the time to alleviation of influenza symptoms in all populations; this efficacy was comparable. No significant improvements were seen in combination therapy groups. The mean difference in the time to alleviation of symptoms ranged from 12.78 to 19.51 h. According to the summarized mean difference and surface under the cumulative ranking curve (SUCRA), peramivir (SUCRA = 82.6%), zanamivir (SUCRA = 64%), and oseltamivir (SUCRA = 55.1%) were the three top-ranking drugs for treating influenza. Zanamivir and peramivir were the preferred pharmacologic intervention among all investigated interventions based on the calculated "value preference of SUCRA." This study is a network meta-analysis to explore the therapeutic effects of NAIs in patients with influenza. Peramivir might be the best choice for reducing the time to alleviation of symptoms.

Cost-effectiveness evaluation of add-on dapagliflozin for heart failure with reduced ejection fraction from perspective of healthcare systems in Asia-Pacific region.

BACKGROUND: With emerging evidence on the efficacy of adding dapagliflozin to standard care for patients with heart failure with reduced ejection fraction (HFrEF), this study assessed the cost-effectiveness of add-on dapagliflozin to standard care versus standard care alone for HFrEF from the perspective of healthcare systems in the Asia-Pacific region. METHODS: A Markov model was applied to project the outcomes of treatment in terms of lifetime medical cost and quality-adjusted life-years. The transition probabilities between health states in the model were obtained from the Dapagliflozin in Patients with Heart Failure and Reduced Ejection Fraction trial. Country-specific costs and utilities were extracted for modeling. The incremental cost-effectiveness ratio against a country-specific willingness-to-pay threshold was applied to determine the cost-effectiveness of treatment. A series of sensitivity analyses were performed to ensure the robustness of the study results. Costs are presented in 2020 United States dollars. RESULTS: The incremental cost-effectiveness ratios for add-on dapagliflozin versus standard care alone were $5277, $9980, $12,305, $16,705, and $23,227 per quality-adjusted life-year gained in Korea, Australia, Taiwan, Japan, and Singapore, respectively. When using add-on dapagliflozin to standard care versus standard care alone, ~ 100% of simulations were cost-effective at a willingness-to-pay threshold of one gross domestic product per capita of the given Asia-Pacific country; however, the probability of being cost-effective for using add-on dapagliflozin decreased when the time horizon for simulation was restricted to 18 months and when the cardiovascular mortality for the two treatments (43.8% and 33.0%, respectively) was assumed to be the same. The cost-effectiveness results were most sensitive to cardiovascular mortality of treatment. CONCLUSIONS: Adding dapagliflozin to standard care is cost-effective for HFrEF in healthcare systems in the Asia-Pacific region, which supports the rational use of dapagliflozin for HFrEF in this region.

Prophylactic management for taxane-induced nail toxicity: A systematic review and meta-analysis.

OBJECTIVE: This meta-analysis was performed to assess the efficacy of cryotherapy and nail solution (NS) use in preventing nail toxicity (NT) induced by taxane-based chemotherapy. METHODS: PubMed, EMBASE, Cochrane Library and ClinicalTrials.gov registry databases were searched for relevant studies published up to December 2018. The primary outcome was taxane-induced NT. Secondary outcomes were skin toxicity (ST), time to toxicity and patient comfort. RESULTS: We reviewed three randomised control trials and six prospective studies with 708 patients. For meta-analysis, taxane-induced NT grading was compared. NT and ST were significantly lower in the cryotherapy patients than in the controls (grade 1 NT: risk ratio [RR] = 0.51, 95% confidence interval [CI] = 0.30-0.89; grade 2-3 NT: RR = 0.36, 95% CI = 0.11-1.12; total NT: RR = 0.49; 95% CI = 0.30-0.79; ST: RR = 0.46, 95% CI = 0.33-0.64). The NS-treated patients exhibited significantly lower NT than the controls. CONCLUSIONS: Nail solution-treated or cryotherapy patients exhibited lower NT incidence and severity associated with taxane-based chemotherapy than the controls. For patients who can afford and comply with NS use or cryotherapy, these measures represent effective prophylactic management for taxane-induced NT and improve their quality of life and functional statuses. Further studies are needed to establish the routine usage protocols, long-term efficacy and safety for these interventions.

Impact and implications of national centralized drug procurement in China.

The national centralized drug procurement (NCDP) policy, known as the "4 + 7" policy in China, has transformed pharmaceutical procurement and access by leveraging healthcare institutions' collective buying power to reduce drug prices substantially. This policy has profoundly impacted drug pricing mechanisms, healthcare expenditures, market dynamics, and the quality of available drugs. This commentary evaluates the efficacy, challenges, and broader implications of the NCDP, summarizes the current state of post-marketing monitoring of selected generic drugs for centralized procurement, and presents relevant considerations.

Anti-inflammatory quinoline-4(1H)-one derivatives from the aerial parts of Waltheria indica linn.

Eight previously undescribed quinoline-4(1H)-one derivatives (1-8) and five known analogues (9-13) were isolated from the 95% aqueous extract of the aerial parts of Waltheria indica Linn. Their chemical structures were determined by analyzing 1D NMR, 2D NMR and HRESIMS data comprehensively. Compounds 1-8 possess diverse side chains at C-5 of quinoline-4(1H)-one or tetrahydroquinolin-4(1H)-one skeleton. The absolute configurations were assigned via comparison of the experimental and calculated ECD spectra, and analysis of the ECD data of the in situ formed [Rh2(OCOCF3)4] complex. Additionally, all 13 isolated compounds were evaluated for their anti-inflammatory activities by measuring the inhibitory effects of nitric oxide (NO) production in lipopolysaccharide-induced BV-2 cells. Compounds 2, 5 and 11 showed moderate inhibition toward NO production with IC50 values of 40.41 ± 1.01, 60.09 ± 1.23 and 55.38 ± 0.52 µM, respectively.

Associations between chronic stress and hair cortisol in children: A systematic review and meta-analysis.

OBJECTIVES: This review systematically examined the associations between chronic stress and hair cortisol concentration (HCC) in children, and the potential modification effects of type, measurement period and scales of chronic stress, child age and sex, hair length and HCC measurement method, characteristics of study site, and congruence between time periods measured for chronic stress and HCC. METHODS: Pubmed, Wed of Science, and APA PsycINFO were systematically searched for articles examining the association between chronic stress and HCC. RESULTS: Thirteen studies from five countries with 1,455 participants were included in the systematic review and nine studies were included in the meta-analysis. Meta-analysis revealed that chronic stress was associated with HCC (pooled-r = 0.09, 95 % CI: 0.03, 0.16). Stratified analyses revealed that type, measurement time and scales of chronic stress, hair length and measurement method of HCC, and the congruence between time periods measured for chronic stress and HCC modified such correlations. The positive correlations between chronic stress and HCC were significant for studies measuring chronic stress as stressful life events, assessing chronic stress within the past six months, extracting HCC from 1 cm, 3 cm, or 6 cm of hair, measuring HCC by LC-MS/MS, or having congruence between time periods measured for chronic stress and HCC. The potential modifying effects of sex and country developmental status could not be concluded due to the limited number of studies included. CONCLUSIONS: Chronic stress was positively correlated with HCC, varying by characteristics and measurements of chronic stress and HCC. HCC could be a biomarker for chronic stress among children.

Inhaled corticosteroid for patients with COVID-19: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The efficacy of inhaled corticosteroid (ICS) in the treatment of patients with COVID-19 has been evaluated in randomized controlled trials (RCTs), however, their findings are not consistent. METHODS: PubMed, Embase, Cochrane Library, ClinicalTrials.gov, Scopus, Web of Science and Google Scholar were searched to June 10, 2023. Only RCTs that investigated the clinical efficacy and safety of ICS for patients with COVID-19 were included. RESULTS: Eleven RCTs were included. ICS users had significantly higher rate of symptom alleviation at day 14 than the control group (risk ratio [RR], 1.13; 95% CI, 1.04-1.23; I2 = 42%). Additionally, no significant difference between the ICS users and the control group was observed in the composite outcome of urgent care, emergency department (ED) visit or hospitalization (RR, 0.43; 95% CI, 0.08-2.48; I2 = 85%) and hospitalization or death (RR, 0.85; 95% CI, 0.64-1.12; I2 = 0%). Finally, ICS user had a non-significantly lower risk of death at day 28 than the control group (0.63% vs 0.99%; RR, 0.82; 95% CI, 0.43-1.56; I2 = 0%). CONCLUSIONS: Additional ICS use, particularly inhaled budesonide may help symptom relief in patients with COVID-19. However, ICS use did not help reduce the risk of urgent care, ED visit, hospitalization, or death.

Preterm infants' biobehavioral responses to caregiving and positioning over 24 hours in a neonatal unit in Taiwan.

This prospective, descriptive study used a repeated-measures design to explore preterm infants' biobehavioral responses to 24-hour neonatal caregiving and positioning, and the factors associated with changes in their biobehavioral responses. Thirty preterm infants (gestational age 27.6-36.1 weeks) were observed for 3 days to record biobehavioral responses. Infants' disorganized behaviors increased as caregiving intrusiveness and supine positioning increased. Social interactions did not lead to increases in infants' disorganized behaviors, but to increased regulatory behaviors. Non-nutritive sucking (NNS), and prone positioning reduced occurrences of infant disorganized behaviors. Routine caregiving increased instability of oxygen saturation, but lateral and prone positioning improved physiological stability. Clinicians can appropriately provide NNS, positioning, and social interactions to promote biobehavioral stability.

Comparative Gut Microbiome in Trachypithecus leucocephalus and Other Primates in Guangxi, China, Based on Metagenome Sequencing.

The Trachypithecus leucocephalus (white-headed langur) is a highly endangered, karst-endemic primate species, inhabiting the karst limestone forest in Guangxi, Southwest China. How white-headed langurs adapted to karst limestone and special dietary remains unclear. It is the first time to study the correlation between the gut microbiome of primates and special dietary, and environment in Guangxi. In the study, 150 fecal samples are collected from nine primates in Guangxi, China. Metagenomic sequencing is used to analyze and compare the gut microbiome composition and diversity between white-headed langurs and other primates. Our results indicate that white-headed langurs has a higher diversity of microbiome than other primates, and the key microbiome are phylum Firmicutes, class Clostridia, family Lachnospiraceae, and genera Clostridiates and Ruminococcus, which are related to the digestion and degradation of cellulose. Ten genera are significantly more abundant in white-headed langurs and François' langur than in other primates, most of which are high-temperature microbiome. Functional analysis reveals that energy synthesis-related pathways and sugar metabolism-related pathways are less abundant in white-headed langurs and François' langur than in other primates. This phenomenon could be an adaptation mechanism of leaf-eating primates to low-energy diet. The gut microbiome of white-headed langurs is related to diet and karst limestone environment. This study could serve as a reference to design conservation breeding, manage conservation units, and determine conservation priorities.

Association of sepsis-induced cardiomyopathy and mortality: a systematic review and meta-analysis.

BACKGROUND: The implication of sepsis-induced cardiomyopathy (SIC) to prognosis is controversial, and its association with mortality at different stages remains unclear. We conducted a systematic review and meta-analysis to understand the association between SIC and mortality in septic patients. METHODS: We searched and appraised observational studies regarding the mortality related to SIC among septic patients in PubMed and Embase from inception until 8 July 2021. Outcomes comprised in-hospital and 1-month mortality. We adopted the random-effects model to examine the mortality risk ratio in patients with and without SIC. Meta-regression, subgroup, and sensitivity analyses were applied to examine the outcome's heterogeneity. RESULTS: Our results, including 20 studies and 4,410 septic patients, demonstrated that SIC was non-statistically associated with increased in-hospital mortality, compared to non-SIC (RR 1.28, [0.96-1.71]; p = 0.09), but the association was statistically significant in patients with the hospital stay lengths longer than 10 days (RR 1.40, [1.02-1.93]; p = 0.04). Besides, SIC was significantly associated with a higher risk of 1-month mortality (RR 1.47, [1.17-1.86]; p < 0.01). Among SIC patients, right ventricular dysfunction was significantly associated with increased 1-month mortality (RR 1.72, [1.27-2.34]; p < 0.01), while left ventricular dysfunction was not (RR 1.33, [0.87-2.02]; p = 0.18). CONCLUSIONS: With higher in-hospital mortality in those hospitalized longer than 10 days and 1-month mortality, our findings imply that SIC might continue influencing the host's system even after recovery from cardiomyopathy. Besides, right ventricular dysfunction might play a crucial role in SIC-related mortality, and timely biventricular assessment is vital in managing septic patients.

Clinical efficacy of SGLT2 inhibitors with different SGLT1/SGLT2 selectivity in cardiovascular outcomes among patients with and without heart failure: A systematic review and meta-analysis of randomized trials.

BACKGROUND: Some sodium-glucose co-transporter-2 (SGLT2) inhibitors showed benefits on heart failure (HF), but different SGLT2/SGLT1 selectivity might influence the treatment effect. This study aimed to meta-analyze the treatment effects of SGLT2 inhibitors and the diversity of receptor selectivity for patients with and without HF. METHODS: Randomized controlled trials were searched in PubMed, Embase, Cochrane databases and ClinicalTrials.gov registry from inception to October 2020. The interest outcomes were analyzed with random-effects models and presented with a risk ratio (RR) and 95% confidence interval (CI). Subgroup analyses examined the treatment effects among SGLT2 inhibitors with different SGLT2/SGLT1 selectivity. RESULTS: The final analyses included 10 trials and 52,607 patients. The RR of total cardiovascular (CV) death or hospitalization for HF (HHF) between SGLT2 inhibitors and placebo was 0.79 (95% CI 0.74-0.84, I2 = 31%). With SGLT2 inhibitors, HF patients had reduced mortality risks (RR 0.89, 95% CI 0.80-0.99, I2 = 0), and non-HF patients had lower risks of major adverse CV events (RR 0.92, 95% CI 0.85-0.99, I2 = 0). The risk reduction of HHF was consistent in groups of HF (RR 0.72, 95% CI 0.64-0.80, I2 = 8%) and non-HF (RR 0.74, 95% CI 0.61-0.89, I2 = 0), but the effect of the low SGLT2/SGLT1 selectivity inhibitor was insignificant in non-HF patients. CONCLUSION: The efficacy of SGLT2 inhibitors on risk reduction of total CV death or HHF is consistent with the previous studies. The regimen is beneficial for reducing mortality in patients with HF and major adverse CV events in those without HF. Different SGLT2/SGLT1 selectivity may differ in the treatment effects in patients with and without HF.

Topical antibiotic prophylaxis for surgical wound infections in clean and clean-contaminated surgery: a systematic review and meta-analysis.

BACKGROUND: Topical antibiotics are widely prescribed as prophylaxis for surgical site infection (SSI). Despite giving high drug concentrations at local wound sites, their efficacy remains controversial. This study is a systematic review and meta-analysis designed to compare the efficacy and safety of topical antibiotics with non-antibiotic agents in preventing SSI. METHODS: Randomized controlled trials (RCTs) comparing topical antibiotics in patients with clean and clean-contaminated postsurgical wounds were included. Relevant trials published before 30 September 2020, were searched in the PubMed, Embase, and Cochrane databases, without language restrictions. The primary outcome was the incidence of SSIs, presented as the event rate. The secondary outcome was the incidence of contact dermatitis (safety outcome). Data were synthesized using the random-effects model, with the results expressed as risk ratio (RR) with 95 per cent confidence intervals (c.i.). RESULTS: Thirteen RCTs were included. The incidence of SSIs and contact dermatitis showed no significant difference between topical antibiotics and non-antibiotic agents (RR 0.89, 95 per cent c.i. 0.59 to 1.32 (P = 0.56, I2 = 48 per cent); and RR 2.79, 95 per cent c.i. 0.51 to 15.19 (P = 0.24, I2 = 0 per cent), respectively). In the subgroup analyses, a reduction in SSIs was also not observed in dermatological (RR 0.77, 95 per cent c.i. 0.39 to 1.55; P = 0.46, I2 = 65 per cent), ocular (RR 0.08, 95 per cent c.i. 0.00 to 1.52; P = 0.09), spinal (RR 1.34, 95 per cent c.i. 0.65 to 2.77; P = 0.43, I2 = 0 per cent), orthopaedic (RR 0.69, 95 per cent c.i. 0.37 to 1.29; P = 0.25, I2 = 0 per cent), or cardiothoracic surgeries (RR 1.60, 95 per cent c.i. 0.79 to 3.25; P = 0.19). CONCLUSION: Given the current evidence, the routine application of topical antibiotics to surgical wounds did not reduce the incidence of SSI. Further trials are needed to assess their effectiveness in high-risk surgeries or in selected patient groups.

Circulating lipid and lipoprotein profiles and their correlation to cardiac function and cardiovascular outcomes in patients with acute myocardial infarction.

Recent studies showed that lipoproteins represent major risk factors, both positive and negative, for atherosclerotic cardiovascular disease. The aim of the present study was to describe the relationship between plasma lipid profile and cardiac function and cardiovascular outcomes in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI). Two independent groups of subjects including a total of 797 patients diagnosed of AMI undergoing PCI admitted to the First Affiliated Hospital of Xi'an Jiaotong University were included in the present study. We performed a cross-sectional study for the correlation between plasma lipid profile and cardiac function based on the first group, including 503 patients with AMI. We further validated the correlation and did the follow-up of 2.4 years of major cardiovascular outcomes on the second group, including 294 patients with AMI. Our results showed that apolipoprotein A-I (ApoA-I) level was significantly reduced, and the high-density lipoprotein cholesterol (HDL-C):ApoA-I ratio was increased in the patients with lower LVEF or higher N-terminal pro-B-type natriuretic peptide levels compared with the control; there was a positive correlation between cardiac function and ApoA-I, and a negative correlation between cardiac function and the HDL-C:ApoA-I ratio. Meanwhile, multivariate Cox analysis showed that ApoA-I was independent predictors of major adverse cardiovascular events (MACEs). Kaplan-Meier survival analysis showed the ApoA-I levels exhibited a significant effect on predicting the incidence of MACEs. In sum, plasma ApoA-I level is positively associated with the cardiac function of patients with AMI after PCI, and ApoA-I is an independent indicator to predict the incidence of MACEs.

HDL-C/apoA-I Ratio Is Associated with the Severity of Coronary Artery Stenosis in Diabetic Patients with Acute Coronary Syndrome.

BACKGROUND: Emerging evidence demonstrates that the lipid metabolism in acute coronary syndrome (ACS) patients with type 2 diabetes mellitus (T2DM) differs from nondiabetic patients. However, the distinct lipid profiles and their relationships with the severity of coronary artery stenosis and prognosis in patients with T2DM remain elusive. METHOD AND RESULT: This single-center, prospective cohort study enrolled 468 patients diagnosed with ACS undergoing coronary angiography, consisting of 314 non-DM and 154 DM patients. The HDL-C/apoA-I ratio was significantly higher in DM patients with a multivessel (≥3 affected vessels) lesion than a single-vessel (1-2 affected vessels) lesion. Regression analyses showed that the HDL-C/apoA-I ratio was positively correlated to the number of stenotic coronary arteries in DM patients but not non-DM patients. However, Kaplan-Meier survival analysis revealed no significant difference in the major adverse cardiovascular event rate regarding different HDL-C/apoA-I levels in DM or non-DM ACS patients at the end of the 2-year follow-up. CONCLUSION: A higher HDL-C/apoA-I ratio is associated with increased severity of coronary artery stenosis in DM patients with ACS but not with the rate of major adverse cardiovascular events at the end of the 2-year follow-up.

The gut microbiota is associated with clinical response to statin treatment in patients with coronary artery disease.

BACKGROUND: The structure and composition of the gut microbiota influence patients' response to therapeutic interventions. It is also known that the response to statin treatment can vary greatly from one patient to another, suggesting a possible connection between microbiome composition and response to statins. In the present study, we aim to explore the influence of the microbiome composition on the response to statin treatment among patients with coronary artery disease (CAD). METHODS: A prospective cohort of 836 CAD patients enrolled from January 2016 to December 2017 was used to perform a nested case-control study. We divided 110 CAD patients into two groups according to their response to statins (good response group and poor response group) and compared their gut microbiota. RESULTS: Our analysis reveals no significant difference in microbiome between the two groups. However, significant differences were found in the relative proportion of numerous genera between GR and PR groups. Most remarkably, we could observe that a poor response to statin treatment correlates to a significant decrease in the abundance of beneficial bacteria for the lipid metabolism (Akkermansia muciniphila (A. muciniphila) and Lactobacillus) and a significant increase in the abundance of bacteria (Holdemanella and Facecallibacterium). CONCLUSIONS: Gut microbiota structure is associated with the response to statin. Our results suggest that manipulation of the gut microbiota composition can be an interesting and effective treatment strategy to blood lipid control among CAD patients.

Emerging Severe Acute Respiratory Syndrome Coronavirus 2 Mutation Hotspots Associated With Clinical Outcomes and Transmission.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of the ongoing coronavirus disease 2019 (COVID-19) pandemic. Understanding the influence of mutations in the SARS-CoV-2 gene on clinical outcomes is critical for treatment and prevention. Here, we analyzed all high-coverage complete SARS-CoV-2 sequences from GISAID database from January 1, 2020, to January 1, 2021, to mine the mutation hotspots associated with clinical outcome and developed a model to predict the clinical outcome in different epidemic strains. Exploring the cause of mutation based on RNA-dependent RNA polymerase (RdRp) and RNA-editing enzyme, mutation was more likely to occur in severe and mild cases than in asymptomatic cases, especially A > G, C > T, and G > A mutations. The mutations associated with asymptomatic outcome were mainly in open reading frame 1ab (ORF1ab) and N genes; especially R6997P and V30L mutations occurred together and were correlated with asymptomatic outcome with high prevalence. D614G, Q57H, and S194L mutations were correlated with mild and severe outcome with high prevalence. Interestingly, the single-nucleotide variant (SNV) frequency was higher with high percentage of nt14408 mutation in RdRp in severe cases. The expression of ADAR and APOBEC was associated with clinical outcome. The model has shown that the asymptomatic percentage has increased over time, while there is high symptomatic percentage in Alpha, Beta, and Gamma. These findings suggest that mutation in the SARS-CoV-2 genome may have a direct association with clinical outcomes and pandemic. Our result and model are helpful to predict the prevalence of epidemic strains and to further study the mechanism of mutation causing severe disease.

Cost-Effectiveness Evaluation of Add-on Empagliflozin in Patients With Heart Failure and a Reduced Ejection Fraction From the Healthcare System's Perspective in the Asia-Pacific Region.

Background: EMPEROR-Reduced trial provides promising evidence on the efficacy of empagliflozin adding to the standard treatment in patients with heart failure and reduced ejection fraction (HFrEF). This study aimed to investigate the cost-effectiveness of add-on empagliflozin vs. standard therapy alone in HFrEF from the perspective of the Asia-Pacific healthcare systems. Methods: A Markov model was constructed to simulate HFrEF patients and to project the lifetime direct medical costs and quality-adjusted life years (QALY) of both therapies. Transitional probabilities were derived from the EMPEROR-Reduced trial. Country-specific costs and utilities were extracted from published resources. Incremental cost-effectiveness ratio (ICER) against willingness to pay (WTP) threshold was used to examine the cost-effectiveness. A series of sensitivity analyses was performed to ensure the robustness of the results. Results: The ICERs of add-on empagliflozin vs. standard therapy alone in HFrEF were US$20,508, US$24,046, US$8,846, US$53,791, US$21,543, and US$20,982 per QALY gained in Taiwan, Japan, South Korea, Singapore, Thailand, and Australia, respectively. Across these countries, the probabilities of being cost-effective for using add-on empagliflozin under the WTP threshold of 3-times country-specific gross domestic product per capita were 93.7% in Taiwan, 95.6% in Japan, 96.3% in South Korea, 94.2% Singapore, 51.9% in Thailand, and 95.9% in Australia. The probabilities were reduced when shortening the time horizon, assuming the same cardiovascular mortality for both treatments, and setting lower WTP thresholds. Conclusion: Adding empagliflozin to HFrEF treatment is expected to be a cost-effective option among the Asia-Pacific countries. The cost-effectiveness is influenced by the WTP thresholds of different countries.

Small-molecule arone protects from neuroinflammation in LPS-activated microglia BV-2 cells by targeting histone-remodeling chaperone ASF1a.

Histone post-translational modifications (PTMs) have been shown to be highly associated with inflammation response, suggesting a therapeutic significance of pharmacologically editing histone PTMs. Currently reported anti-inflammation small-molecules mainly target histone PTMs writers or erasers for methylation, phosphorylation, and acetylation. Although histone chaperones also appear to be involved in inflammation signaling cascades, whether small-molecules could target histone chaperones to show anti-inflammation effects has still been rarely discovered. In this study, natural product artone was found to show obvious inhibitory effects on microglia-mediated neuroinflammation by directly targeting ASF1a, which is a histone-remodeling chaperone. Mechanism study revealed that artone modulated histone H3 PTMs profile by down-regulating acetylation and trimethylation modification levels at sites K4, K9, K18 and K27. Artone-dependent regulations on PTMs further caused an effective inhibition on transcription factor NF-κB assembling to promoters of pro-inflammatory cytokine genes including Tnf-α, Il-6 and Rgs3, indicating a distinctive anti-neuroinflammation mechanism. Collectively, we reported artone as the first small-molecule targeting histone-remodeling chaperone ASF1a for anti-neuroinflammation. Moreover, these findings broaden our knowledge of histone chaperone as a druggable target protein for neuroinflammation inhibition, and open a new avenue to novel therapy strategy for inflammation-associated neurological disorders.

Cystatin C-Based Renal Function in Predicting the Long-Term Outcomes of Chronic Total Occlusion After Percutaneous Coronary Intervention.

Renal function estimated by various biomarkers predicting for adverse cardiovascular events has not been well-identified in received percutaneous coronary intervention (PCI) for chronic total occlusion (CTO), the advanced stages of atherosclerosis. We aim to determine whether the serum cystatin C-based-estimated glomerular filtration rate (eGFR) can have an improved predictive value in patients with CTO lesions undergoing PCI as compared with multiple creatinine-based estimates of kidney function. Six hundred and seventy-one patients received CTO PCI were retrospectively included in the study. The eGFR was calculated by modification of diet in renal disease equation for Chinese (cMDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations at baseline, respectively. Then, the cohort was categorized into three groups according to standard KDIGO kidney stages based on eGFR. The primary endpoint was all-cause mortality, and the secondary endpoint was cardiac death. Strikingly, cystatin C-based eGFR showed a better performance with the greater area being under the receiver operating characteristic (ROC) curve (0.73 for all-cause mortality and 0.73 for cardiac death, separately) and a better assessment for survival free from adverse event across renal levels among four eGFR equations. Compared with eGFR calculated by other formulas, serum cystatin C-based eGFR showed the highest prognostic value for both all-cause mortality (adjusted HR 3.6, 95% CI 1.6-8.1, P = 0.002) and cardiac death (adjusted HR 2.9, 95% CI 1.0-8.1, P = 0.028). Moreover, cystatin C-based eGFR significantly improved the risk reclassification of event with a high value of net reclassification improvement and integrated discrimination improvement. This study may prove that cystatin C-based eGFR is a better predictor of both all-cause mortality and cardiac death than other equations in populations with CTO undergoing PCI.

[Rethinking oxygen therapy for premature infants in terms of oxidative stress].

Oxygen therapy is one of the most common interventions in the care of premature infants in the neonatal intensive care unit (NICU). Premature infants are at risk of oxidant injury due to inadequate anti-oxidant defenses. Common complications of premature infants such as retinopathy, chronic lung disease, intraventricular hemorrhaging, and periventricular leukomalacia may also be associated with secondary oxidant injuries. This article explores relationships between oxygen and complications linked to premature delivery. It also outlines correct concepts and practices of oxygen therapy for NICU nurses to reduce the oxygen-related complications associated with premature births and promote the health and life quality of premature infants.
