Daunorubicin and cytarabine for certain types of poor-prognosis acute myeloid leukemia: a systematic literature review

ABSTRACT Introduction: Induction chemotherapy based on anthracyclines and cytarabine (Ara-C) combination remains the standard of care for acute myeloid leukemia (AML) patients who are considered candidate for intensive and curative approaches. However, the toxicity of this regimen is high, with disappointing clinical outcomes among the so-called poor-prognosis AML subsets, which generally refer to patients with adverse cytogenetic risk, secondary AML including therapy-related AML, poor-prognosis mutations, especially FLT3-ITD, and relapse/refractory AML. Areas covered: To the best of our knowledge, the role and efficacy of 7 + 3 schedules containing daunorubicin (DNR) and Ara-C for certain types of poor-prognosis AML has not been systematically assessed. A critical approach to the role of DNR and Ara-C induction could be relevant to establish which patients should be enrolled in clinical trials using novel therapies. Expert commentary: In this regard, a recent randomized clinical trial (RCT) showed improved results in older patients with sAML or high-risk cytogenetics who received CPX-351 compared with standard 7 + 3 combination. We perform a systematic literature review to analyze the clinical outcomes reported with DNR plus Ara-C regimens in adult patients with poor-prognosis AML, the use of liposomal formulations of DNR and Ara-C and the RCTs which compared standard 7 + 3 with the addition of a third drug.
Composite Magnetic Photocatalyst Bi5O7I/MnxZn1−xFe2O4: Hydrothermal-Roasting Preparation and Excellent Photocatalytic Activity

A new composite magnetic photocatalyst, Bi5O7I/MnxZn1−xFe2O4, prepared by a hydrothermal-roasting method was studied. The photocatalytic properties of Bi5O7I/MnxZn1−xFe2O4 were evaluated by degradation of Rhodamine B (RhB) under simulated sunlight irradiation, and the structures and properties were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), ultraviolet-visible light (UV-Vis) diffuse reflectance spectra (DRS), and a vibrating sample magnetometer (VSM). The results indicated that Bi5O7I/MnxZn1−xFe2O4 was an orthorhombic crystal, which was similar to that observed for Bi5O7I. Bi5O7I/MnxZn1−xFe2O4 consisted of irregularly shaped nanosheets that were 40–60 nm thick. The most probable pore size was 24.1 nm and the specific surface area was 7.07 m2/g. Bi5O7I/MnxZn1−xFe2O4 could absorb both ultraviolet and visible light, and the energy gap value was 3.22 eV. The saturation magnetization, coercivity and residual magnetization of Bi5O7I/MnxZn1−xFe2O4 were 3.9 emu/g, 126.6 Oe, and 0.7 emu/g respectively, which could help Bi5O7I/MnxZn1−xFe2O4 be separated and recycled from wastewater under the action of an external magnetic field. The recycling experiments revealed that the average recovery rate of the photocatalyst was 90.1%, and the photocatalytic activity was still more than 81.1% after five cycles.
Impact of socioeconomic inequalities on quality of life in oral submucous fibrosis patients.

AIM The purpose of this study was to analyze the impact of socioeconomic characteristics on oral health-related quality of life (OHRQoL) in patients with oral submucous fibrosis (OSF). METHODS A total of 300 OSF patients' quality of life (QoL) data were obtained using OHRQoL-OSF and global self ratings of oral health and overall wellbeing. The socioeconomic status (SES) of participants was analyzed by using modified Kuppuswamy scale. RESULTS OSF patients with lower SES had worse OHRQoL as compared with those with middle and upper SES (p < 0.001). The household income of the family was found to be strongly associated with poor OHRQoL. CONCLUSION Socioeconomic characteristics should be considered in the holistic management of OSF as it has been strongly associated with the OHRQoL of these patients.
Epidemiology of Exertional Heat Illnesses in National Collegiate Athletic Association Athletes During the 2009-2010 Through 2014-2015 Academic Years.

CONTEXT Exertional heat illnesses (EHIs) among football athletes have been widely researched, but data examining all collegiate sports are limited. OBJECTIVE To describe the epidemiology of EHI in 25 National Collegiate Athletic Association (NCAA) sports. DESIGN Descriptive epidemiology study. SETTING The NCAA Injury Surveillance Program during the 2009-2010 through 2014-2015 academic years. PATIENTS OR OTHER PARTICIPANTS A voluntary sample of 166 NCAA institutions over 2048 team-seasons. MAIN OUTCOME MEASURE(S) Athletic trainers reported EHIs to the NCAA Injury Surveillance Program. Only EHIs sustained during a sanctioned practice or competition were included. The EHI rate, specific diagnoses, and number of emergency transports were measured. RESULTS Overall, 232 EHI events were reported (0.47/10 000 athlete-exposures [AEs]; 95% confidence interval [CI] = 0.41, 0.53). Football comprised 75% of all EHI events and had the largest rate (1.55/10 000 AEs; 95% CI = 1.32, 1.78). The overall EHI rate was higher in preseason practices (1.16/10 000 AEs) than all other time periods (regular and postseason practices and all competitions; 0.23/10 000 AEs, injury rate ratio [IRR] = 4.96; 95% CI = 3.79, 6.50). This result was retained when examining the individual sports of football (3.65/10 000 versus 0.63/10 000 AEs, IRR = 5.82; 95% CI = 4.18, 8.10), men's soccer (1.11/10 000 versus 0.07/10 000 AEs, IRR = 16.819; 95% CI = 1.89, 138.55), and women's soccer (1.10/10 000 versus 0.05/10 000 AEs, IRR = 22.52; 95% CI = 2.77, 183.05). The EHI rates were highest in states with elevated annual temperatures (1.05/10 000 AEs). Heat cramps (39%), heat exhaustion (27%), and dehydration (29%) were the most common types of EHI. Nineteen athletes with EHI (8%) required emergency transport. CONCLUSIONS Football players continue to experience the most EHIs; however, EHIs can potentially occur in all NCAA sports. Continued emphasis on preseason EHI policies and institution-specific environmental guidelines is needed to address EHI rates.
Intralesional Collagenase Clostridium histolyticum Causes Meaningful Improvement in Men with Peyronie's Disease: Results of a Multi-Institutional Analysis

Purpose: In a multi-institutional setting we studied the efficacy and safety outcomes at multiple high volume centers where collagenase Clostridium histolyticum is used to treat Peyronie's disease. Materials and Methods: We collected retrospective data on consecutive patients with Peyronie's disease who underwent treatment with collagenase C. histolyticum between April 2014 and March 2018 at a total of 5 institutions. Included in the study were 918 patients. Main outcomes of interest included the change in curvature after receiving collagenase C. histolyticum therapy and the frequency of serious treatment related adverse events. The 2-tailed paired Student t-test was used to compare continuous variables. Univariate and multivariate regression analyses were performed to assess predictors of the success of collagenase C. histolyticum therapy to improve curvature. Results: In the cohort of 918 patients curvature improved from a mean of 48.2 degrees before treatment to 32.9 degrees after treatment, a 30.1% improvement from baseline (p <0.0001). Of the men 68.7% had a 20% or greater improvement in curvature. In the 502 patients who completed 4 or more cycles curvature improved from a mean of 49.7 degrees before to 32.7 degrees after treatment, a 33% improvement from baseline (p <0.0001). Of these men 74.4% experienced a 20% or greater improvement in curvature. A complication of treatment developed in 9% of patients. The number of cycles of collagenase C. histolyticum received was predictive of curvature improvement (p <0.0001). Conclusions: This large multi-institutional analysis confirms the safety and efficacy of collagenase C. histolyticum therapy in men with Peyronie's disease. Intralesional collagenase C. histolyticum for Peyronie's disease according to the IMPRESS (Investigation of Maximal Peyronie's Reduction Efficacy and Safety Studies) trial protocol produced an improvement in penile curvature in men with Peyronie's disease with a low rate of complications.
Changes in the spatial distribution of the under-five mortality rate: Small-area analysis of 122 DHS surveys in 262 subregions of 35 countries in Africa

The under-five mortality rate (U5MR) is a critical and widely available population health indicator. Both the MDGs and SDGs define targets for improvement in the U5MR, and the SDGs require spatial disaggregation of indicators. We estimate trends in the U5MR for Admin-1 subnational areas using 122 DHS surveys in 35 countries in Africa and assess progress toward the MDG target reductions for each subnational region and each country as a whole. In each country, direct weighted estimates of the U5MR from each survey are calculated and combined into a single estimate for each Admin-1 region across five-year periods. Our method fully accounts for the sample design of each survey. The region-time-specific estimates are smoothed using a Bayesian, space-time model that produces more precise estimates (when compared to the direct estimates) at a one-year scale that are consistent with each other in both space and time. The resulting estimated distributions of the U5MR are summarized and used to assess subnational progress toward the MDG 4 target of two-thirds reduction in the U5MR during 1990–2015. Our space-time modeling approach is tractable and can be readily applied to a large collection of sample survey data. Subnational, regional spatial heterogeneity in the levels and trends in the U5MR vary considerably across Africa. There is no generalizable pattern between spatial heterogeneity and levels or trends in the U5MR. Subnational, small-area estimates of the U5MR: (i) identify subnational regions where interventions are still necessary and those where improvement is well under way; and (ii) countries where there is very little spatial variation and others where there are important differences between subregions in both levels and trends. More work is necessary to improve both the data sources and methods necessary to adequately measure subnational progress toward the SDG child survival targets.
Sit-to-stand exercise programs improve sit-to-stand performance in people with physical impairments due to health conditions: a systematic review and meta-analysis

Abstract Purpose: To determine the effects of sit-to-stand exercise programs on patient-related outcomes in people with physical impairments due to health conditions. Methods: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered prospectively. Seven electronic databases were systematically searched for relevant articles. Inclusion and exclusion criteria were used to screen the titles and abstracts of articles identified using the key search terms of sit-to-stand and exercise. Only randomized controlled trials were included. The methodological quality of papers was assessed using the Cochrane risk of bias tool. Results: A total of eight trials were included. A meta-analysis was conducted using four of the trials that focused on patients with neurological conditions. There was moderate-quality evidence that sit-to-stand exercise programs improve sit-to-stand performance, but no evidence from another meta-analysis that sit-to-stand training improved balance for patients with neurological conditions. There was also no evidence from individual trials that positive changes occurred in the outcomes of gait speed and distance, lower limb muscle strength, falls, or participation. Conclusions: Sit-to-stand training could be a useful intervention when patients have limited sit-to-stand function and the aim of treatment is to improve this performance. IMPLICATIONS FOR REHABILITATION Sit-to-stand training could be a useful intervention for patients when the aim is to improve sit-to-stand performance. Sit-to-stand training may not be a useful intervention when the aim is to improve other functions such as balance.
Clinical profile of uveitis patients developing central serous chorioretinopathy: An experience at a tertiary eye care center in India

Purpose: To evaluate clinical profile of patients with uveitis who developed central serous chorioretinopathy (CSC). Methods: Retrospective case series of consecutive patients of uveitis with CSC managed at a tertiary eye care center in India between 1994 and 2014. The data about clinical features, investigations, treatment, and outcomes were obtained from their medical records. Results: A total of 31 eyes of 26 patients with uveitis with a diagnosis of CSC between June 1994 and May 2014 were included in the study. The mean age of presentation was 42.8 ± 9.2 years, and 88.4% of the patients were male. CSC was bilateral in 19.2% of the patients, and in 38.4% patients uveitis was because of infectious etiology. CSC developed in 23 (88.5%) patients when they were on oral corticosteroid. The most common cause of uveitis in our study was choroiditis (48.4%), followed by retinal vasculitis (12.9%). The mean time for resolution of CSC was relatively less in patients with uveitis because of infectious etiology. In 10% eyes vision remained the same and deterioration of vision was noted in 19% eyes. Best corrected visual acuity of the patients at the time of presentation with CSC was 0.56 ± 0.34 and after the resolution of CSC was 0.48 ± 0.5 (P < 0.0005). Conclusion: Patients with choroidal inflammations are more prone to develop CSC compared with other subtypes of uveitis. Management of CSC in uveitis can be challenging.
Overexpression of miR-210 promotes the potential of cardiac stem cells against hypoxia

Abstract Objective. To evaluate the effects of miR-210 on cardiac stem cells (CSCs) against hypoxia-induced injury. Methods. CSCs were isolated from rat ventricular wall and cultured until passage 4. After exposure to hypoxia for 6 h, the expression of miR-210 was determined. Thereafter, transfection of miR-210 mimic and inhibitor was carried out. 1 week later, in vitro experiments were performed to measure the expression of caspase-8-associated protein 2 (Casp8ap2), Caspase 8, protein tyrosine phosphatase, non-receptor type 2 (PTPN2) and CXC chemokine receptor 4 (CXCR4), as well as migration and apoptosis of CSCs under hypoxic condition. Results. Hypoxia induced a significant up-regulation of miR-210 expression in CSCs. Notably, the expression of Casp8ap2, Caspase8, PTPN2 was dramatically inhibited by overexpression of miR-210 in CSCsmiR-210 Group (P < .05), but no changes in CXCR4 (P > .05), compared with the control. Additionally, a decreased apoptosis of CSCs was detected in CSCsmiR-210 Group (26.22 ± 1.15%, P < .001), compared with Control Group (34.97 ± 0.63%). Moreover, the migration of CSCs was significantly promoted in CSCsmiR-210 Group (45.73 ± 2.4, P < .001), compared with Control Group (19.6 ± 1.11). Meanwhile, down-regulation of miR-210 reversed these results (P < .05). Conclusions. miR-210 was a hypoxia responsive element in CSCs, and its up-regulation inhibited apoptosis of CSCs and promoted their migration under hypoxic condition, through regulating its target genes Casp8ap2/Caspase 8 and PTPN2, which may provide a new strategy for cell therapy of ischemic heart disease.
Macroscopic and microscopic evaluation of flapless alveolar perforations on experimental tooth movement

Abstract Objective: The aim of this study was to evaluate a flapless surgical technique as an alternative to traditional alveolar corticotomy used to accelerate orthodontic tooth movement (OTM). Methods: To induce OTM in Wistar rats, 40 cN of orthodontic force were applied to the maxillary left first molars. Forty rats were distributed into control groups (CG1, CG3, CG7 and CG14) and experimental groups (n= 5), in which alveolar perforations were made using a spear-shaped guide bur (EG1, EG3, EG7, EG14). Euthanasia dates were set at 1, 3, 7 and 14 days, respectively, after tooth movement began. The amount of OTM was measured with a caliper, and osteoclasts present in the periodontal ligament of the mesial root of the moved tooth were counted by means of histological evaluation (tartrate-resistant acid phosphatase staining, TRAP). Results: Although there was no difference in the amount of OTM within subgroups of corresponding experimental periods (p> 0.05), when EG14 and CG14 were compared, a larger number of osteoclasts was counted in the experimental group (p< 0.00). Conclusion: The authors concluded that flapless cortical alveolar perforations led to more intense osteoclastic activity on the fourteenth day; nevertheless, no evidence of accelerated OTM could be noted.
A Transductive Model-based Stress Recognition Method Using Peripheral Physiological Signals

Existing research on stress recognition focuses on the extraction of physiological features and uses a classifier that is based on global optimization. There are still challenges relating to the differences in individual physiological signals for stress recognition, including dispersed distribution and sample imbalance. In this work, we proposed a framework for real-time stress recognition using peripheral physiological signals, which aimed to reduce the errors caused by individual differences and to improve the regressive performance of stress recognition. The proposed framework was presented as a transductive model based on transductive learning, which considered local learning as a virtue of the neighborhood knowledge of training examples. The degree of dispersion of the continuous labels in the y space was also one of the influencing factors of the transductive model. For prediction, we selected the epsilon-support vector regression (e-SVR) to construct the transductive model. The non-linear real-time features were extracted using a combination of wavelet packet decomposition and bi-spectrum analysis. The performance of the proposed approach was evaluated using the DEAP dataset and Stroop training. The results indicated the effectiveness of the transductive model, which had a better prediction performance compared to traditional methods. Furthermore, the real-time interactive experiment was conducted in field studies to explore the usability of the proposed framework.
HIV-1 nuclear import in macrophages is regulated by CPSF6-capsid interactions at the nuclear pore complex

Nuclear entry of HIV-1 replication complexes through intact nuclear pore complexes is critical for successful infection. The host protein cleavage-and-polyadenylation-specificity-factor-6 (CPSF6) has been implicated in different stages of early HIV-1 replication. Applying quantitative microscopy of HIV-1 reverse-transcription and pre-integration-complexes (RTC/PIC), we show that CPSF6 is strongly recruited to nuclear replication complexes but absent from cytoplasmic RTC/PIC in primary human macrophages. Depletion of CPSF6 or lack of CPSF6 binding led to accumulation of HIV-1 subviral complexes at the nuclear envelope of macrophages and reduced infectivity. Two-color stimulated-emission-depletion microscopy indicated that under these circumstances HIV-1 complexes are retained inside the nuclear pore and undergo CA-multimer dependent CPSF6 clustering adjacent to the nuclear basket. We propose that nuclear entry of HIV-1 subviral complexes in macrophages is mediated by consecutive binding of Nup153 and CPSF6 to the hexameric CA lattice.
Surgical approach and the impact of epidural analgesia on survival after esophagectomy for cancer: A population-based retrospective cohort study

BACKGROUND Esophagectomy for esophageal cancer carries high morbidity and mortality, particularly in older patients. Transthoracic esophagectomy allows formal lymphadenectomy, but leads to greater perioperative morbidity and pain than transhiatal esophagectomy. Epidural analgesia may attenuate the stress response and be less immunosuppressive than opioids, potentially affecting long-term outcomes. These potential benefits may be more pronounced for transthoracic esophagectomy due to its greater physiologic impact. We evaluated the impact of epidural analgesia on survival and recurrence after transthoracic versus transhiatal esophagectomy. METHODS A retrospective cohort study was performed using the linked Surveillance, Epidemiology and End Results (SEER)-Medicare database. Patients aged ≥66 years with locoregional esophageal cancer diagnosed 1994-2009 who underwent esophagectomy were identified, with follow-up through December 31, 2013. Epidural receipt and surgical approach were identified from Medicare claims. Survival analyses adjusting for hospital esophagectomy volume, surgical approach, and epidural use were performed. A subgroup analysis restricted to esophageal adenocarcinoma patients was performed. RESULTS Among 1,921 patients, 38% underwent transhiatal esophagectomy (n = 730) and 62% underwent transthoracic esophagectomy (n = 1,191). 61% (n = 1,169) received epidurals and 39% (n = 752) did not. Epidural analgesia was associated with transthoracic approach and higher volume hospitals. Patients with epidural analgesia had better 90-day survival. Five-year survival was higher with transhiatal esophagectomy (37.2%) than transthoracic esophagectomy (31.0%, p = 0.006). Among transthoracic esophagectomy patients, epidural analgesia was associated with improved 5-year survival (33.5% epidural versus 26.5% non-epidural, p = 0.012; hazard ratio 0.81, 95% confidence interval [0.70, 0.93]). Among the subgroup of esophageal adenocarcinoma patients undergoing transthoracic esophagectomy, epidural analgesia remained associated with improved 5-year survival (hazard ratio 0.81, 95% confidence interval [0.67, 0.96]); this survival benefit persisted in sensitivity analyses adjusting for propensity to receive an epidural. CONCLUSION Among patients undergoing transthoracic esophagectomy, including a subgroup restricted to esophageal adenocarcinoma, epidural analgesia was associated with improved survival even after adjusting for other factors.
PM2.5 exposure induces systemic inflammation and oxidative stress in an intracranial atherosclerosis rat model

Exposure to airborne particle (PM2.5) is a risk factor for intracranial atherosclerosis (ICA). Because of the established role of systemic inflammation and oxidative stress by PM2.5, we determined whether these processes account for PM2.5‐mediated ICA, and also whether omega‐3 fatty acid (O3FA) dietary supplementation could attenuate them.
