3Stem cell therapy and diabetic erectile dysfunction:A critical review显示文摘Erectile dysfunction(ED)has been identified as one of the most frequent chronic complications of diabetes mellitus(DM).The prevalence of ED is estimated to be about 67.4%in all DM cases worldwide.The pathophysiological process leading to ED involves endothelial,neurological,hormonal,and psychological factors.In DM,endothelial and neurological factors play a crucial role.Damages in the blood vessels and erectile tissue due to insulin resistance are the hallmark of ED in DM.The current treatments for ED include phosphodiesterase-5 inhibitors and penile prosthesis surgery.However,these treatments are limited in terms of just relieving the symptoms,but not resolving the cause of the problem.The use of stem cells for treating ED is currently being studied mostly in experimental animals.The stem cells used are derived from adipose tissue,bone,or human urine.Most of the studies observed an improvement in erectile quality in the experimental animals as well as an improvement in erectile tissue.However,research on stem cell therapy for ED in humans remains to be limited.Nevertheless,significant findings from studies using animal models indicate a potential use of stem cells in the treatment of ED.Cennikon Pakpahan Raditya Ibrahim William William Zakiyatul Faizah Juniastuti Juniastuti Maria I Lusida Delvac Oceandy 2021World Journal of Stem Cells2021,13,10:6
4Urinary nuclear magnetic resonance spectroscopy of a Bangladeshi cohort with hepatitis-B hepatocellular carcinoma: A biomarker corroboration study显示文摘AIM: To establish if a distinct urinary metabolic profile could be identified in Bangladeshi hepatitis-B hepatocellular carcinoma(HCC) patients compared to cirrhosis patients and controls. METHODS: Urine samples from 42 Bangladeshi patients with HCC(39 patients with hepatitis-B HCC), 47 with cirrhosis on a background of hepatitis B, 46 with chronic hepatitis B, and seven ethnically-matched healthy controls were analyzed using nuclear magnetic resonance(NMR) spectroscopy. A full dietary and medication history was recorded for each subject. The urinary NMR data were analyzed using principal component analysis(PCA) and orthogonal partial leastsquared discriminant analysis(OPLS-DA) techniques. Differences in relative signal levels of the most discriminatory metabolites identified by PCA and OPLSDA were compared between subject groups using an independent samples Kruskal-Wallis one-way analysis of variance(ANOVA) test with all pairwise multiple comparisons. Within the patient subgroups, the MannWhitney U test was used to compare metabolite levels depending on hepatitis B e-antigen(HBe Ag) status and treatment with anti-viral therapy. A BenjaminiHochberg adjustment was applied to acquire the level of significance for multiple testing, with a declared level of statistical significance of P < 0.05.RESULTS: There were significant differences in age(P < 0.001), weight(P < 0.001), and body mass index(P < 0.001) across the four clinical subgroups. Serum alanine aminotransferase(ALT) was significantly higher in the HCC group compared to controls(P < 0.001); serum α-fetoprotein was generally markedly elevated in HCC compared to controls; and serum creatinine levels were significantly reduced in the HCC group compared to the cirrhosis group(P = 0.004). A threefactor PCA scores plot showed clustering of the urinary NMR spectra from the four subgroups. Metabolites that contributed to the discrimination between the subgroups included acetate, creatine, creatinine, dimethyamine(DMA), formate, glycine, hippurate, and trimethylamine-N-oxide(TMAO). A comparison of relative metabolite levels confirmed that carnitine was significantly increased in HCC; and creatinine, hippurate, and TMAO were significantly reduced in HCC compared to the other subgroups. HBe Ag negative patients showed a significant increase in creatinine(P = 0.001) compared to HBe Ag positive patients in the chronic hepatitis B subgroup, whilst HBe Ag negative patients showed a significant decrease in DMA(P = 0.004) in the cirrhosis subgroup compared to HBe Ag positive patients. There were no differences in metabolite levels in HCC patients who did or did not receive antiviral treatment. CONCLUSION: Urinary NMR changes in Bangladeshi HCC were identified, corroborating previous findings from Egypt and West Africa. These findings could form the basis for the development of a cost-effective HCC dipstick screening test.I Jane Cox Abil E Aliev Mary ME Crossey Mahvish Dawood Mamun Al-Mahtab Sheikh M Akbar Salimur Rahman Antonio Riva Roger Williams Simon D Taylor-Robinson 2016World Journal of Gastroenterology2016,22,16:4

7Fluctuation of visual analog scale pain scores and opioid consumption before and after total hip arthroplasty显示文摘BACKGROUND Patients who undergo orthopedic procedures are often given excess opioid medication.Understanding the relationship between pain and opioid consumption following total hip arthroplasty(THA)is key to creating safe and effective opioid prescribing guidelines.AIM To evaluate the association between the quantity of opioid consumption in relation to pain scores both pre-and postoperatively in patients undergoing primary THA.METHODS We retrospectively reviewed patients who underwent primary THA from November 2018-May 2019 and answered both the visual analog scale(VAS)pain and opioid medication questionnaires pre-and postoperatively.Both surveys were delivered daily for 7-days before surgery through the first 30 postoperative days.Survey results were divided into preoperative,postoperative days 1-7,postoperative days 8-14,and postoperative days 15-30 for analysis.Mean opioid pill consumption and VAS pain scores in each time period were determined and compared to patients’preoperative status using hierarchical Poisson and linear regressions,respectively.RESULTS There were 105 patients included.Mean VAS pain scores were the highest preoperatively 7.41±1.72.However,VAS pain scores significantly declined in each successive postoperative category compared to preoperative scores:postoperative day 1-7(5.07±1.79;P<0.001),postoperative day 8-14(3.60±1.64;P<0.001),and postoperative day 15-30(3.15±1.63;P<0.001).Mean opioid pill consumption preoperatively was 0.68±1.29 pills.Compared to preoperative opioid consumption,opioid use was significantly greater between postoperative days 1-7(1.51±1.58;P=0.001)and postoperative days 8-14(1.00±1.27;P=0.043).Opioid consumption declined below preoperative levels between postoperative days 15-30(0.35±0.72;P=0.160)which correlates with a VAS pain score of 3.15.CONCLUSION All patients experienced significant benefit and pain relief from having undergone THA.Average postoperative opioid consumption decreased below preoperative consumption between postoperative days 15-30,which was associated with a VAS pain score of 3.15.These results can be used to appropriately guide opioid prescribing practices and set patient expectations regarding pain management following THA.Vivek Singh Alex Tang Thomas Bieganowski Utkarsh Anil William Macaulay Ran Schwarzkopf Roy I Davidovitch 2022World Journal of Orthopedics2022,13,8:2

10Strategies to tackle the challenges of external beam radiotherapy for liver tumors显示文摘Primary and metastatic liver cancer is an increasingly common and difficult to control disease entity.Radiation offers a non-invasive treatment alternative for these patients who often have few options and a poor prognosis.However,the anatomy and aggressiveness of liver cancer poses significant challenges such as accurate localization at simulation and treatment,management of motion and appropriate selection of dose regimen.This article aims to review the options available and provide information for the practical implementation and/or improvement of liver cancer radiation programs within the context of stereotactic body radiotherapy and image-guided radiotherapy guidelines.Specific patient inclusion and exclusion criteria are presented given the significant toxicity found in certain sub-populations treated with radiation.Indeed,certain sub-populations,such as those with tumor thrombosis or those with larger lesions treated with transarterial chemoembolization,have been shown to have significant improvements in outcome with the addition of radiation and merit special consideration.Implementing a liver radiation programrequires three primary challenges to be addressed:(1) immobilization and motion management;(2) localization;and(3) dose regimen and constraint selection.Strategies to deal with motion include simple internal target volume(ITV) expansions,non-gated ITV reduction strategies,breath hold methods,and surrogate marker methods to enable gating or tracking.Localization of the tumor and organs-at-risk are addressed using contrast infusion techniques to take advantage of different normal liver and cancer vascular anatomy,imaging modalities,and margin management.Finally,a dose response has been demonstrated and dose regimens appear to be converging.A more uniform approach to treatment in terms of technique,dose selection and patient selection will allow us to study liver radiation in larger and,hopefully,multicenter randomized studies.Michael I Lock Jonathan Klein Hans T Chung Joseph M Herman Edward Y Kim William Small Nina A Mayr Simon S Lo 2017World Journal of Hepatology2017,9,14:2
