Association between kidney stones and poor sleep factors in U.S. adults.

The purpose of our study is to examine the correlation between sleep factors and the prevalence of kidney stones in US adults. A total of 34,679 participants from the National Health and Nutrition Examination Survey 2007 to 2018 were included in the analyses. Sleep data collection included: presleep factors (difficulty falling asleep, sleep onset latency), intra-sleep factors (risk index of obstructive sleep apnea, restless leg syndrome, difficulty maintaining sleep), post-sleep factors (daytime sleepiness, non-restorative sleep), sleep schedule and duration, and sleep quality.

Pharmaceutical Manipulation of Mitochondrial F0F1-ATP Synthase Enables Imaging and Protection of Myocardial Ischemia/Reperfusion Injury Through Stress-induced Selective Enrichment.

To rescue ischemic myocardium from progressing to myocardial infarction, timely identification of the infarct size and reperfusion is crucial. However, fast and accurate identification, as well as the targeted protection of injured cardiomyocytes following ischemia/reperfusion (I/R) injury, remain significantly challenging. Here, a near infrared heptamethine dye IR-780 is shown that has the potential to quickly monitor the area at risk following I/R injury by selectively entering the cardiomyocytes of the at-risk heart tissues.

Hyaluronic Acid-Conjugated Fluorescent Probe-Shielded Polydopamine Nanomedicines for Targeted Imaging and Chemotherapy of Bladder Cancer.

Bladder cancer is one of the most common malignancies in the urinary system, with high risk of recurrence and progression. However, the difficulty in detecting small tumor lesions and the lack of selectivity of intravesical treatment seriously affect the prognosis of patients with bladder cancer. In the present work, a nanoparticle-based delivery system with tumor targeting, high biocompatibility, simple preparation, and the ability to synergize imaging and therapy was fabricated.

Sulfhydryl functionalized hyaluronic acid hydrogels attenuate cyclophosphamide-induced bladder injury.

Clinical management of cyclophosphamide (CYP) results in numerous side effects including hemorrhagic cystitis (HC), which is characterized by inflammation and oxidative stress damage. Intravesical hyaluronic acid (HA) supplementation, a therapeutic method to restore barrier function of bladder, avoid the stimulation of metabolic toxicants on bladder and reduce inflammatory response, has shown good results in acute or chronic bladder diseases. However, there are unmet medical needs for the treatment of HC to temporarily restore bladder barrier and reduce inflammation.

Hyperbaric oxygen enhanced the chemotherapy of mitochondrial targeting molecule IR-780 in bladder cancer.

Background: Bladder cancer has a high rate of recurrence and drug resistance due to the lack of effective therapies. IR-780 iodide, a near-infrared (NIR) mitochondria-targeting fluorescent agent, has been demonstrated to achieve higher selectivity than other drugs in different tumor types and exhibited tumor-killing effects in some cancers. However, this therapeutic strategy is rarely studied in bladder cancer.

Intravesical IR-780 instillation prevents radiation cystitis by protecting urothelial integrity.

Purpose: To explore an efficient preventive strategy for radiation cystitis.

Methods: We instilled IR-780 into the bladders of rats 1 h before bladder irradiation, and its bio-distribution was observed at different times. Bladders were then examined for pathogenic alterations and inflammation levels by day 3 and week 12 postirradiation, and the functional characteristics of the bladder were tested via cystometry by week 12.

IR-61 Improves Voiding Function Mitochondrial Protection in Diabetic Rats.

Diabetic bladder dysfunction (DBD) afflicts nearly half of diabetic patients, but effective treatment is lacking. In this study, IR-61, a novel heptamethine cyanine dye with potential antioxidant effects, was investigated to determine whether it can alleviate DBD. Rats were intraperitoneally injected with IR-61 or vehicle after diabetes was induced with streptozotocin.

The near-infrared dye IR-61 restores erectile function in a streptozotocin-induced diabetes model via mitochondrial protection.

This study aimed to evaluate the therapeutic effect of IR-61, a novel mitochondrial heptamethine cyanine dye with antioxidant effects, on diabetes mellitus-induced erectile dysfunction (DMED). Eight-week-old male Sprague-Dawley rats were intraperitoneally injected with streptozotocin (STZ) to induce type 1 diabetes. Eight weeks after STZ injection, all rats were divided into three groups: the control group, DM group, and DM + IR-61 group.

Eye Drops of Metformin Prevents Fibrosis After Glaucoma Filtration Surgery in Rats Activating AMPK/Nrf2 Signaling Pathway.

Metformin has effective therapeutic effects in anti-tumor and anti-fibrotic diseases. However, how the antifibrotic effect of metformin in the eye and how it is transferred are still unclear. Here, the eye drop of metformin treatment was studied in Sprague-Dawley (SD) rats of glaucoma filtrating surgery (GFS).

Nocturnal oxygen therapy as an option for early COVID-19.

There is currently no effective antiviral therapy or immune-based treatment for coronavirus disease (COVID-19). The urgent challenge is to prevent the transition of COVID-19 from mild to severe infection. This paper discussed nocturnal oxygen therapy as a new option for people with COVID-19 under home quarantine.

The TβR II-targeted aptamer S58 prevents fibrosis after glaucoma filtration surgery.

Glaucoma filtration surgery (GFS) is an effective clinical treatment for glaucoma when intraocular pressure (IOP) control is poor. However, the occurrence of conjunctival scarring at the surgical site is the main reason for failure of the surgery. In a previous study, we isolated and developed S58, a novel nucleic acid aptamer targeting TβR II, by systematic evolution of ligands by exponential enrichment (SELEX).

Meta-analysis of the effect of postoperative radiotherapy on prognosis of prostatic cancer following radical prostatectomy.

Objective: A systematic evaluation was carried out over the effectiveness and safety of postoperative radiotherapy following radical prostatectomy.

Method: The randomized controlled trials that were concerned with postoperative radiotherapy for prostatic cancer and published before June 2014 were searched in PubMed, EMBASE, Cochrane Library, CBM, CNKI and VIP databases. Two researchers conducted quality evaluation and data extraction independently for all included literature.

Association of Vitamin E Intake with Reduced Risk of Kidney Cancer: A Meta-Analysis of Observational Studies.

Background: Several observational studies suggested that vitamin E intake is related to the risk of kidney cancer; however, the results of published studies are inconsistent.

Material And Methods: A meta-analysis was performed to assess the relationship between vitamin E intake and the risk of kidney cancer by searching PubMed and Medline through August 2015. We computed pooled relative risks (RR) and 95%CI of kidney cancer for the highest versus lowest level of vitamin E intake.

Total retroperitoneal laparoscopic nephroureterectomy with bladder-cuff resection for upper urinary tract transitional cell carcinoma.

Background: Open nephroureterectomy (ONU) and bladder cuff resection (ONU-BCR) has been the gold standard of surgical treatment for upper urinary tract transitional cell carcinoma (UUT-TCC). The aim of this study is to introduce a modified total retroperitoneal laparoscopic nephroureterectomy (LNU) with bladder-cuff resection (LNU-BCR) method for treating UUT-TCC and compare its clinical efficacy with ONU-BCR.

Methods: Sixty-five patients with UUT-TCC, who underwent ONU-BCR (n = 36) or LNU-BCR (n = 29) between January 2008 and June 2012, were analyzed in this retrospective study.
