BACKGROUND Significant gaps in guideline-directed medical therapy(GDMT)for heart failure(HF)stem from shortages of cardiologists and advanced HF providers,as well as a lack of optimal HF management knowledge among hospitalists.This study compared the impact of optimal medical therapy in HF(OMT-HF)certification on GDMT implementation and patient outcomes between an intervention group(IG)of hospitalists and a standard-of-care comparison group(SOC-CG).METHODS This study was implemented from November 2022 to May 2023.Hospitalized car-diology patients with HF and left ventricular ejection fraction≤40%were rando-mized to IG or SOC-CG.Exclusion criteria included patients in cardiogenic shock,unable to consent,or at high risk.Follow-up was at 30 days post-discharge.Diffe-rences between groups were analyzed using Fisher’s exact test for categorical va-riables and Wilcoxon rank-sum or unpaired t-test for continuous variables.Chan-ges in Minnesota Living with Heart Failure Questionnaire(MLWHFQ)scores were evaluated using a paired t-test.RESULTS IG patients had lower readmission rates[9(42.85%)vs 11(17.46%),P=0.03]and a decreased trend in mortality 30-day post discharge.IG patients also showed greater mean improvements in total(-27.03±24.59 vs-5.85±23.52,P<0.001),physical(-13.8±12.3 vs-2.71±11.16,P<0.001)and emotional(-4.76±8.10 vs-1.42±5.98)dimensions on the MLWHFQ compared to SOC-CG,however,change in emotional dimension did not reach statistical significance.CONCLUSION Hospitalist OMT-HF certification may lead to better 30-day outcomes in hospitalized HF patients including quality of life,mortality and readmission rates.Larger prospective studies are warranted to validate these findings. 展开更多

Objective:Accurate measurement of QT interval,the ventricular action potential from depolarization to repolarization,is important for the early detection of Long QT syndrome.The most effective QT correction(QTc)formula has yet to be determined in the pediatric population,although it has intrinsically greater extremes in heart rate(HR)and is more susceptible to errors in measurement.The authors of this study compare six dif-ferent QTc methods(Bazett,Fridericia,Framingham,Hodges,Rautaharju,and a computer algorithm utilizing the Bazett formula)for consistency against variations in HR and RR interval.Methods:Descriptive Retrospective Study.We included participants from a pediatric cardiology practice of a community hospital who had an ECG performed in 2017.All participants were healthy patients with no past medical history and no regular med-ications.Results:ECGs from 95 participants from one month to 21 years of age(mean 9.7 years)were included with a mean HR of 91 beats per minute(bpm).The two-sample paired t-test or Wilcoxon signed-rank test assessed for any difference between QTc methods.A statistically significant difference was observed between every combination of two QTc formulae.The Spearman’s rank correlation analysis explored the QTc/HR and QTc/RR relationships for each formula.Fridericia method was most independent of HR and RR with the lowest absolute value of correlation coefficients.Bazett and Computer had moderate correlations,while Framingham and Rautaharju exhibited strong correlations.Correlations were positive for Bazett and Computer,reflecting results from prior studies demonstrating an over-correction of Bazett at higher HRs.In the linear QTc/HR regression analysis,Bazett had the slope closest to zero,although Computer,Hodges,and Fridericia had comparable values.Alternatively,Fridericia had the linear QTc/RR regression coefficient closest to zero.The Bland-Altman method assessed for bias and the limits of agreement between correction formulae.Bazett and Computer exhibited good agreement with minimal bias along with Framingham and Rautaharju.To account for a possible skewed distri-bution of QT,all the above analyses were also performed excluding the top and bottom 2%of data as sorted by heart rate ranges(N=90).Results from this data set were consistent with those derived from all participants(N=95).Conclusions:Overall,the Fridericia correction method provided the best rate correction in our pedia-tric study cohort. 展开更多

BACKGROUND Metabolic dysfunction-associated steatohepatitis(MASH)is increasingly common,as is hepatocellular carcinoma(HCC)in the background of MASH.Liver transplantation(LT)provides superior long-term survival for patients with unresectable MASH-HCC,but not all patients have equal access to transplant.MASH-HCC disproportionately affects Hispanic patients,but minorities are less likely to undergo LT for HCC.Additionally,females also undergo LT at lower rates than males.AIM To investigate whether race/ethnicity and sex affect LT waitlist outcomes.METHODS Records of adults with MASH-HCC in the United States Organ Procurement and Transplantation Network database listed for LT between 1/2015 and 12/2021 were analyzed.RESULTS Most of the 3810 patients waitlisted for LT for MASH-HCC were non-Hispanic(NH)white(71.2%)or Hispanic(23.4%),with only 49(1.1%)NH Black candidates.Hispanics underwent LT at lower rates than NH whites(71.6%vs 78.4%,P<0.001),but race/ethnicity did not affect waitlist mortality(P=0.06).Patients with Hispanic[hazard ratio(HR)=0.85,95%CI:0.77-0.95,P=0.002]or Asian(HR=0.79,95%CI:0.63-0.98,P=0.04)race/ethnicity were less likely to undergo LT.Women were also less likely to receive LT(male:HR=1.16,95%CI:1.04-1.29,P=0.01).Patients in regions 1 and 9 were less likely to be transplanted as well(P=0.07).CONCLUSION Hispanic patients are less likely to undergo LT for MASH-HCC,concerning given their susceptibility to MASH and HCC.There were very few NH Black candidates.Disparities were also unequal across regions,which is particularly concerning in states where at-risk populations have rising cancer incidence.Additional research is needed to identify strategies for mitigating these differences in access to LT for MASH-HCC. 展开更多

Intrahepatic cholangiocarcinoma(iCCA)is a rare biliary tract cancer with high mortality rate.Complete resection of the iCCA lesion is the first choice of treatment,with good prognosis after margin-negative resection.Unfortunately,only 12%-40% of patients are eligible for resection at presentation due to cirrhosis,portal hypertension,or large tumor size.Liver transplantation(LT)offers margin-negative iCCA extirpation for patients with unresectable tumors.Initially,iCCA was a contraindication for LT until size-based selection criteria were introduced to identify patients with satisfied post-LT outcomes.Recent studies have shown that tumor biology-based selection can yield high post-LT survival in patients with locally advanced iCCA.Another selection criterion is the tumor response to neoadjuvant therapy.Patients with response to neoadjuvant therapy have better outcomes after LT compared with those without tumor response to neoadjuvant therapy.Another index that helps predict the treatment outcome is the biomarker.Improved survival outcomes have also opened the door for living donor LT for iCCA.Patients undergoing LT for iCCA now have statistically similar survival rates as patients undergoing resection.The combination of surgery and locoregional and systemic therapies improves the prognosis of iCCA patients. 展开更多

Driving pressure(ΔP)is a core therapeutic component of mechanical ventilation(MV).Varying levels ofΔP have been employed during MV depending on the type of underlying pathology and severity of injury.However,ΔP levels have also been shown to closely impact hard endpoints such as mortality.Considering this,conducting an in-depth review ofΔP as a unique,outcome-impacting therapeutic modality is extremely important.There is a need to understand the subtleties involved in making sureΔP levels are optimized to enhance outcomes and minimize harm.We performed this narrative review to further explore the various uses ofΔP,the different parameters that can affect its use,and how outcomes vary in different patient populations at different pressure levels.To better utilizeΔP in MV-requiring patients,additional large-scale clinical studies are needed. 展开更多

BACKGROUND The use of opioids for pain is linked to an increased risk of developing opioid use disorder,and has resulted in the emergence of the opioid crisis over the last few years.AIM The systematic review question is“How does the use of opioid medications in pain management,compared with non-opioid medications,affect pain intensity over the short,intermediate,and long-term in adults with acute traumatic pain?”.METHODS The protocol was prospectively registered on the International Prospective Re-gister of Systematic Reviews:CRD42021279639.Medline and Google Scholar were electronically searched for controlled peer-reviewed studies published in full,with the PICO framework:P:Adult patients with traumatic injuries,I:Opioid medications,C:Non-opioid medi-cations,O:A minimum clinically important difference(MCID)in pain.RESULTS After full-text screening,we included 14 studies in the qualitative synthesis.Of these 14 studies,12 were rando-mized clinical trials(RCTs)and 2 were pseudo-RCTs with a total of 2347 patients enrolled.There was heteroge-neity in both medication utilized and outcome in these studies;only two studies were homogeneous regarding the type of study conducted,the opioid used,its comparator,and the outcome explored.The MCID was evaluated in 8 studies,while in 6 studies,any measured pain reduction was considered as an outcome.In 11 cases,the setting of care was the Emergency Department;in 2 cases,care occurred out-of-hospital;and in one case,the setting was not well-specified.The included studies were found to have a low-moderate risk of bias.CONCLUSION Non-opioids can be considered an alternative to opioids for short-term pain management of acute musculoskeletal injury.Intravenous ketamine may cause more adverse events than other routes of administration. 展开更多

Background and Objective:TriNetX is a global,federated,health research network that has become increasingly utilized in academic medicine.In the last 2 years,the field of ophthalmology has seen an uptick in the number of publications of TriNetX analyses.The objective of this review is to summarize the process of conducting a TriNetX study,the trends in TriNetX use,and the utility of TriNetX in ophthalmology research.Additionally,the strengths and limitations of TriNetX use in ophthalmology research will be discussed.Methods:A PubMed and Scopus literature search was performed using the search terms:“TriNetX”and“Ophthalmology”or“Eye”.Included articles were English language only from the years 1994 to June 1,2024.The twenty-one included articles were analyzed for trends in study design,strengths,and weaknesses.Additionally,a mock study was performed to describe the process of completing a TriNetX study.Key Content and Findings:The literature search revealed a marked increase in TriNetX publications in ophthalmology journals in the years 2023 to 2024.Using a methodology similar to the studies identified in the literature search,a mock investigation of the relationship between cataract removal and hip fracture was detailed from start to finish,providing a framework for the use of TriNetX in ophthalmology research.The mock study provided results consistent with previously reported findings.Lastly,a thorough review of the strengths and limitations of TriNetX identified major considerations in study design,coding,data availability,propensity score matching,bias,and analytical challenges that researchers must be aware of when conducting research with TriNetX.However,many of the discussed limitations can be circumvented with careful and informed use of the platform.Conclusions:TriNetX is a powerful research tool that offers volumetric advantages and time efficiency,making it an attractive option for conducting observational studies.Despite its strengths,caution must be exercised when designing studies to ensure their validity and quality.With careful informed use,TriNetX is a valuable resource in ophthalmology research. 展开更多

MR脑灌注成像是MR方法中提供代谢能力度量的唯一途径,对于疾病诊断和治疗效果评估有重要意义。MR灌注成像灌注参数的确定本质上是一个逆问题的求解过程,对一种求逆估计方法—奇异值分解法的逆问题性质进行了研究。在对奇异值分解法进行理论推导后,设计仿真方案,分别针对不同的信噪比进行仿真实验,并对动脉输入函数的延迟与失真进行分析。结果表明,在信噪比分别为150和10时,奇异值分解法都可以有效地估计脑血流量。该方法对动脉输入函数的失真不敏感,但是发生动脉输入函数延迟时,高脑血流量会被低估20%~30%。针对这一情况,对动脉输入函数的延迟效应进行了修正,修正后低估程度减小到±5%,得以明显改善。仿真结果表明,奇异值分解法是一种有效的估计MR灌注成像脑血流量的方法。 展开更多

Locally advanced non-small cell lung cancer(NSCLC) continues to be a challenging disease to treat. With high rates of both local and distant failures, there is signiicant interest in inding more biologically active chemotherapy regimens that can contribute to reduce both failures. The phase III PROCLAIM trial, recently published in the Journal of Clinical Oncology entitled "PROCLAIM: randomized phase III trial of pemetrexed–cisplatin or etoposide–cisplatin plus thoracic radiation therapy followed by consolidation chemotherapy in locally advanced nonsquamous non-small-cell lung cancer", compared two diferent chemotherapy regimens given concurrently with radiotherapy in patients with stage III non-squamous lung cancer: pemetrexed plus cisplatin versus cisplatin plus etoposide. Both groups received consolidation chemotherapy. After enrolling 598 of planned 600 patients, the study was stopped early due to futility as no diference was seen in the primary end-point of overall survival. Since PROCLAIM was designed as a superiority trial, these results suggest that pemetrexed regimens do not ofer a clinical advantage over standard cisplatin plus etoposide. There are some subpopulations who might still beneit from pemetrexed, especially if clinicians are concerned about myelosuppression-related adverse events. Future trials are needed to investigate novel biologic agents and irradiation techniques that can result in more durable local and distant disease control in locally advanced NSCLC. 展开更多

The incidence of biliary injury after laparoscopic cholecystectomy(LC) has shown a declining trend though it may still be twice that as with open cholecystectomy. Major biliary or vasculobiliary injury is associated with significant morbidity. As prevention is the best strategy, the concept of a culture of safe cholecystectomy has been recently introduced to educate surgeons and apprise them of basic tenets of safe performance of LC. Various aspects of safe cholecystectomy include:(1) thorough knowledge of relevant anatomy, various anatomical landmarks, and anatomical variations;(2) an understanding of the mechanisms involved in biliary/vascular injury, the most important being the misidentification injury;(3) identification of various preoperative and intraoperative predictors of difficult cholecystectomy;(4) proper gallbladder retraction;(5) safe use of various energy devices;(6) understanding the critical view of safety, including its doublet view and documentation;(7) awareness of various error traps(e.g., fundus first technique);(8) use of various bailout strategies(e.g., subtotal cholecystectomy) in difficult gallbladder cases;(9) use of intraoperative imaging techniques(e.g., intraoperative cholangiogram) to ascertain correct anatomy; and(10) understanding the concept of time-out.Surgeons should be facile with these aspects of this culture of safety in cholecystectomy in an attempt to reduce the incidence of biliary/vascular injury during LC. 展开更多

Glycogenic hepatopathy(GH) is a rare complication of the poorly controlled diabetes mellitus characterized by the transient liver dysfunction with elevated liver enzymes and associated hepatomegaly caused by the reversible accumulation of excess glycogen in the hepatocytes. It is predominantly seen in patients with longstanding type 1 diabetes mellitus and rarely reported in association with type 2 diabetes mellitus. Although it was first observed in the pediatric population, since then, it has been reported in adolescents and adults with or without ketoacidosis. The association of GH with hyperglycemia in diabetes has not been well established. One of the essential elements in the pathophysiology of development of GH is the wide fluctuation in both glucose and insulin levels. GH and non-alcoholic fatty liver disease(NAFLD) are clinically indistinguishable, and latter is more prevalent in diabetic patients and can progress to advanced liver disease and cirrhosis. Gradient dual-echo MRI can distinguish GH from NAFLD; however, GH can reliably be diagnosed only by liver biopsy. Adequate glycemic control can result in complete remission of clinical, laboratory and histological abnormalities. There has been a recent report of varying degree of liver fibrosis identified in patients with GH. Future studies are required to understand the biochemical defects underlying GH, noninvasive, rapid diagnostic tests for GH, and to assess the consequence of the fibrosis identified as severe fibrosis may progress to cirrhosis. Awareness of this entity in the medical community including specialists is low. Here we briefly reviewed the English literature on pathogenesis involved, recent progress in the evaluation, differential diagnosis, and management. 展开更多

For those who diagnose and treat RCC, it is important to understand the new developments. In recent years, many new renal tumors have been described and defined, and our understanding of the biology and clinical correlates of these tumors is changing. Evolving concepts in Xp11 translocation carcinoma, mucinous tubular and spindle cell carcinoma, multilocular cystic clear cell RCC, and carcinoma associated with neuroblastoma are addressed within this review. Tubulocystic carcinoma, thyroid-like follicular carcinoma of kidney, acquired cystic disease-associated RCC, and clear cell papillary RCC are also described. Finally, candidate entities, including RCC with t(6;11) translocation, hybrid oncocytoma/chromophobe RCC, hereditary leiomyomatosis and RCC syndrome, and renal angiomyoadenomatous tumor are reviewed. Knowledge of these new entities is important for diagnosis, treatment and subsequent prognosis. This review provides a targeted summary of new developments in RCC. 展开更多

Irritable bowel syndrome(IBS) is a common, sometimes debilitating, gastrointestinal disorder worldwide. While altered gut motility and sensation, as well as aberrant brain perception of visceral events, are thought to contribute to the genesis of symptoms in IBS, a search for an underlying aetiology has, to date, proven unsuccessful. Recently, attention has been focused on the microbiota as a possible factor in the pathogenesis of IBS. Prompted by a number of clinical observations, such as the recognition of the de novo development of IBS following enteric infections, as well as descriptions of changes in colonic bacterial populations in IBS and supported by clinical responses to interventions, such as antibiotics and probiotics, that modify the microbiota, various approaches have been taken to investigating the microbiota-host response in IBS, as well as in animal models thereof. From such studies a considerable body of evidence has accumulated to indicate the activation or upregulation of both factors involved in bacterial engagement with the host as well host defence mechanisms against bacteria. Alterations in gut barrier function, occurring in response, or in parallel, to changes in the microbiota, have also been widely described and can be seen to play a pivotal role in generating and sustaining host immune responses both within and beyond the gut. In this manner a plausible hypothesis, based on an altered microbiota and/or an aberrant host response, for the pathogenesis, of at least some instances of IBS, can be generated. 展开更多

AIM To determine if topical application of platelet-rich plasma(PRP) to diabetic foot ulcers(DFUs) results in superior healing rates. METHODS A systematic review was registered with PROSPERO and performed using PRISMA guidelines. Level Ⅰ-Ⅳ investigations of topical PRP application in DFUs were sought in multiple databases including: MEDLINE, Web of Science, and Cochrane Central Register of Controlled Trials. The search terms used were "platelet rich plasma", "diabetes", "ulcers", and "wound". The Modified Coleman Methodology Score(MCMS) was used to analyze study methodological quality. Study heterogeneity and a mostly non-comparative nature of evidence precluded meta-analysis. Only the outcome measurements used by more than 50% of the studies were included in the data synthesis to increase power of the measurement over that of individual studies. A weighted mean of healing rate per week between PRP group vs controls were compared using two-sample z-tests using P-value of less than 0.05 for significance.RESULTS One thousand two hundred and seventeen articles were screened. Eleven articles(322 PRP subjects, 126 controls, PRP subject mean age 58.4 ± 7.2 years, control mean age 58.7 ± 5.9 years) were analyzed. Six articles were level Ⅱ evidence, four were level Ⅲ, and one article was level Ⅳ. The mean MCMS was 61.8 ± 7.3. Healing rate was significantly faster with PRP application compared to controls(0.68 ± 0.56 cm2/wk vs 0.39 ± 0.09 cm2/wk; P < 0.001). Mean heal time to > 90% of the original ulcer area was 7.8 ± 2.7 wk and 8.3 ± 3.7 wk for patients in the PRP group and control groups, respectively(P = 0.115). There were significantly lower adverse effects reported with PRP application compared to controls(7 wound infections, 1 contact dermatitis vs 14 wound infections, 1 maceration; P < 0.001).CONCLUSION The topical application of PRP for DFUs results in statistically superior healing rates and lower complication rates compared to controls. 展开更多

AIM: To study clinical and histopathological features of nonalcoholic fatty liver disease(NAFLD) in patients with and without type 2 diabetes mellitus(T2DM) using updated nonalcoholic steatohepatitis clinical research network(NASH-CRN) grading system.METHODS: We retrospectively analyzed data of 235 patients with biopsy proven NAFLD with and without T2 DM.This database was utilized in the previously published study comparing ethnicity outcomes in NAFLD by the same corresponding author.The pathology database from University of Chicago was utilized for enrolling consecutive patients who met the criteria for NAFLD and their detailed clinical and histopathology findings were obtained for comparison.The relevant clinical profile of patients was collected from the Electronic Medical Records around the time of liver biopsy and the histology was read by a single well-trained histopathologist.The updated criteria for type 2 diabetes have been utilized for analysis.Background data of patients with NASH and NAFLD has been included.The mean differences were compared using χ2 and t-test along with regression analysis to evaluate the predictors of NASH and advanced fibrosis.RESULTS: Patients with NAFLD and T2 DM were significantly older(49.9 vs 43.0,P < 0.01),predominantly female(71.4 vs 56.3,P < 0.02),had higher rate of metabolic syndrome(88.7 vs 36.4,P < 0.01),had significantly higher aspartate transaminase(AST)/alanine transaminase(ALT) ratio(0.94 vs 0.78,P < 0.01) and Fib-4 index(1.65 vs 1.06,P < 0.01) as markers of NASH,showed higher mean NAFLD activity score(3.5 vs 3.0,P = 0.03) and higher mean fibrosis score(1.2 vs 0.52,P < 0.01) compared to patients with NAFLD without T2 DM.Furthermore,advanced fibrosis(32.5 vs 12.0,P < 0.01) and ballooning(27.3 vs 13.3,P < 0.01) was significantly higher among patients with NAFLD and T2 DM compared to patients with NAFLD without T2 DM.On multivariate analysis,T2 DM was independently associated with NASH(OR = 3.27,95%CI: 1.43-7.50,P < 0.01) and advanced fibrosis(OR = 3.45,95%CI: 1.53-7.77,P < 0.01) in all patients with NAFLD.There was a higher rate of T2DM(38.1 vs 19.4,P < 0.01) and cirrhosis(8.3 vs 0.0,P = 0.01) along with significantly higher mean Bilirubin(0.71 vs 0.56,P = 0.01) and AST(54.2 vs 38.3,P < 0.01) and ALT(78.7 vs 57.0,P = 0.01) level among patients with NASH when compared to patients with steatosis alone.The mean platelet count(247 vs 283,P < 0.01) and high-density lipoprotein cholesterol level(42.7 vs 48.1,P = 0.01) was lower among patients with NASH compared to patients with steatosis.CONCLUSION: Patients with NAFLD and T2 DM tend to have more advanced stages of NAFLD,particularly advanced fibrosis and higher rate of ballooning than patients with NAFLD without T2 DM. 展开更多

As surgical techniques continue to move towards less invasive techniques,single incision laparoscopic surgery(SILS),a hybrid between traditional multiport laparoscopy and natural orifice transluminal endoscopic surgery,was introduced to further the enhanced outcomes of multiport laparoscopy. The safety and feasibility of SILS for both benign and malignant colorectal disease has been proven. SILS provides the potential for improved cosmesis,postoperative pain,recovery time,and quality of life at the drawback of higher technical skill required. In this article,we review the history,describe the available technology and techniques,and evaluate the benefits and limitations of SILS for colorectal surgery in the published literature. 展开更多
