Polyethylene glycol microspheres loaded with irinotecan for arterially directed embolic therapy of metastatic liver cancer

AIM To study tumor response, and tolerability of arterially directed embolic therapy(ADET) with polyethylene glycol embolics loaded with irinotecan for the treatment of colorectal cancer liver metastases(CRC-LM). Secondary objectives were to monitor quality of life, time to progression and survival of patients.METHODS Patients were included in the study if they were affected by CRC-LM, refractory to systemic chemotherapy, treated with ADET using polyethylene glycol embolics, and had liver involvement < 50%. Tumor response, performance status(PS), tumor marker antigens, and quality of life(QoL) were monitored at 1, 3 and 6 mo after ADET. QoL was assessed with the Palliative Performance Scale(PPS).RESULTS We treated 50 consecutive CRC-LM patients with ADET using polyethylene glycol embolics. Their tumor response one month after ADET was: 28% of complete response(CR), 48% of partial response(PR), 8% stable disease(SD), and 16% of progression. Tumor response 3 mo after ADET was CR 24%, PR 38%, SD 19% and progression disease(PD) 19%. Tumor response 6 mo after ADET was CR 18%, PR 44%, SD 21% and PD 18%. QoL was 90% PPS at each time point. Median time to progression for patients who progressed was 2.5 mo(range 0.8-6). Median follow-up was 14 mo(0.8-25 range). ADETs were performed with no complications. Observed side effects(mild or moderate intensity) were: Pain in 32% of patients, increase of transaminase levels in 20% and fever in 14%, whereas 30% of patients did not complain any adverse event. CONCLUSION The treatment of unresectable CRC-LM with ADET using polyethylene glycol microspheres loaded with irinotecan was effective in tumor response and resulted in mild toxicity, and good QoL.

Use of Chinese Herbal Medicine Therapies in Comprehensive Hospitals in Central China: A Parallel Survey in Cancer Patients and Clinicians

Summary： Chinese herbal medicine （CHM）, as the largest application category of traditional Chinese medicine （TCM）, is widely accepted among cancer patients in China. Herbal slice （HS） and Chinese patent drug （CPD） are commonly used CHM in China. This study aimed to investigate the utilization of CHM among clinicians and cancer patients in central China. Five hundred and twenty-five patients and 165 clinicians in 35 comprehensive hospitals in central China were asked to complete an anonymous questionnaire that was designed to evaluate the use of CHM. The results showed that 90.74% clinicians and 72.24% cancer patients used CHM during cancer treatment. The educational backgrounds of the clinicians and the age, education level, annual income, and cancer stage of the cancer patients were re- lated to use of CHM. More than 90% clinicians and cancer patients had used CPD. Comparatively, the percentage of HS use was 10% lower than that of CPD use among clinicians and cancer patients. More clinicians preferred to use CHM after surgery than cancer patients did （20.41% vs. 5.37%）. Enhancing physical fitness and improving performance status were regarded as the most potential effect of CHM on cancer treatment （85.71% among clinicians and 94.07% among cancer patients）, in comparison with directly killing tumor cells （24.49% among clinicians and 31.36% among patients）. As for refusal rea- sons, imprecise efficacy was the unanimous （100%） reason for clinicians＇ rejection of CHM, and 95.58% patients objected to using CHM also for this reason. Furthermore, the side effects of CHM were more concerned by clinicians than by patients （33.33% vs. 15.81%）. In conclusion, our survey revealed that CHM was popularly accepted by clinicians and cancer patients in central China. The reasons of use and rejection of CHM were different between clinicians and cancer patients.

ANTITUMOR EFFECTS OF POLYETHYLENE GLYCOLMODIFIED RECOMBINANT HUMAN INTERLEUKIN-2 ON MOUSE UTERINE CERVICAL CARCINOMA IN VIVO

Polyethylene glycol (PEG-8000)-modified recombinant human interleukin-2 (PEG-rIL-2) is a cytokine with prolonged circulatory half-life. In this paper, the antitumor effects of PEG-afL-2 against mouse uterine cervical carcinoma (U14) transplanted intraperitoneally or subcutaneously is reported. PEG-rIL-2 at different doses was administered intraperitoneally. The results showed that PEG-rIL-2 (4500 IU, i.p., QD5) prolonged survival time of mice bearing ascites tumor as compared to rIL-2 (P<0.01), but PEG-rIL-2 at lower doses was without therapeutic effect. In addition, compared to rIL-2, PEG-rIL-2 at different doses (1500-13500 IU, s.c.,QD5) caused significant dose-dependent growth inhibition of solid tumor (P<0.01) when the treatment started at day 4 after subcutaneous inoculation of tumor.

Impact of cardiologist intervention on guideline-directed use of statin therapy

BACKGROUND Statins have an important and well-established role in the prevention of atherosclerotic cardiovascular disease(ASCVD).However,several studies have reported widespread underuse of statins in various practice settings and populations.Review of relevant literature reveals opportunities for improvement in the implementation of guideline-directed statin therapy(GDST).AIM To examine the impact of cardiologist intervention on the use of GDST in the ambulatory setting.METHODS Patients with at least one encounter at the adult Internal Medicine Clinic(IMC)and/or Cardiology Clinic(CC),who had an available serum cholesterol test performed,were evaluated.The 2 comparison groups were defined as:(1)Patients only seen by IMC;and(2)Patients seen by both IMC and CC.Patients were excluded if variables needed for calculation of ASCVD risk scores were lacking,and if demographic information lacked guideline-directed treatment recommendations.Data were analyzed using student t-tests or χ^2,as appropriate.Analysis of Variance was used to compare rates of adherence to GDST.RESULTS A total of 268 patients met the inclusion criteria for this study;211 in the IMC group and 57 in the IMC-CC group.Overall,56%of patients were female,mean age 56 years(±10.65,SD),22%Black or African American,56%Hispanic/Latino,14%had clinical ASCVD,13%current smokers,66%diabetic and 63%hypertensive.Statin use was observed in 55%(n=147/268)of the entire patient cohort.In the IMC-CC group,73.6%(n=42/57)of patients were prescribed statin therapy compared to 50.7%(n=107/211)of patients in the IMC group(P=0.002).In terms of appropriate statin use based on guidelines,there was no statistical difference between groups[IMC-CC group 61.4%(n=35/57)vs IMC group,55.5%(n=117/211),P=0.421].Patients in the IMC-CC group were older,had more cardiac risk factors and had higher proportions of non-white patients compared to the IMC group(P<0.02,all).CONCLUSION Although overall use of GDST was suboptimal,there was no statistical difference in appropriate statin use based on guidelines between groups managed by general internists alone or co-managed with a cardiologist.These findings highlight the need to design and implement strategies to improve adherence rates to GDST across all specialties.

Gene targeted and immune therapies for nodal and gastrointestinal follicular lymphomas

Follicular lymphoma(FL)is the most common indolent B-cell lymphoma(BCL)globally.Recently,its incidence has increased in Europe,the United States,and Asia,with the number of gastrointestinal FL cases expected to increase.Genetic abnormalities related to t(14;18)translocation,BCL2 overexpression,NF-κB pathway-related factors,histone acetylases,and histone methyltransferases cause FL and enhance its proliferation.Meanwhile,microRNAs are commonly used in diagnosing FL and predicting patient prognosis.Many clinical trials on novel therapeutics targeting these genetic abnormalities and immunomodulatory mechanisms have been conducted,resulting in a marked improvement in therapeutic outcomes for FL.Although developing these innovative therapeutic agents targeting specific genetic mutations and immune pathways has provided hope for curative options,FL treatment has become more complex,requiring combinatorial therapeutic regimens.However,optimal treatment combinations have not yet been achieved,highlighting the importance of a complete understanding regarding the pathogenesis of gastrointestinal FL.Accordingly,this article reviews key research on the molecular pathogenesis of nodal FL and novel therapies targeting the causative genetic mutations.Moreover,the results of clinical trials are summarized,with a particular focus on treating nodal and gastrointestinal FLs.

Off-label use of targeted therapies in oncology

Off-label use is defined by the prescription of a marketed drug outside the conditions described in the summary of product characteristics.In oncology,off-label prescribing of targeted therapies may occur in patients with other tumor types expressing the same target.Agents associated to phenotypic approaches such as therapies against the tumoral vasculature(anti-angiogenic drugs) and new immunotherapies(checkpoint inhibitors) also carry the potential of alternative indications or combinations.Off-label use of targeted therapies is little documented and appears to be in the same range than that regarding older drugs with wide variations among agents.When compared with older agents,off-label use of targeted therapies is probably more rational through tumoral genotyping but is faced with a limited clinical support,reimbursement challenges related to the very high pricing and the cost of genotyping or molecular profiling,when applicable.

An Overview of the Connection between Hoarding Disorder and Substance Use Disorder

This essay explores the connections between Hoarding Disorder and Substance Use Disorder,two distinct mental health conditions with clear diagnostic criteria in the DSM-5.Hoarding Disorder,marked by excessive possession accumulation and difficulties in letting go,affects 2-6%of the global population,leading to severe consequences.Potential causes include genetic predisposition,neural issues,and traumatic experience.Substance Use Disorder is influenced by more societal factors.Both disorders share a comorbidity in Attention-Deficit/Hyperactivity Disorder(ADHD).Network analysis shows a strong direct relationship between Hoarding Disorder and ADHD,while social influences increase ADHD prevalence in Substance Use Disorder individuals.Moreover,both disorders benefit from Cognitive Behavioral Therapy(CBT).Exposure and Ritual Prevention effectively address hoarding symptoms,while CBT for Substance Use Disorder focuses on the interplay between thoughts,emotions,and actions.Despite being classified as a mental illness in DSM-5,Hoarding Disorder receives less attention than Substance Use Disorder.This essay aims to raise awareness of Hoarding Disorder by highlighting its commonalities with Substance Use Disorder in terms of causes,comorbidities,and treatment approaches.

Combination of "low-dose" ribavirin and interferon alfa-2a therapy followed by interferon alfa-2a monotherapy in chronic HCV-infected nonresponders and relapsers after interferon alfa-2a monotherapy

AIM To report on the efficacy, safety and tolerability of interferon alfa-2a combined with a "low dose" of ribavirin for relapsers and non responders to alpha interferon monotherapy.METHODS Thirty-four chronic hepatitis C virus-infected non-responders to interferon alfa2a monotherapy (a course of at least 3 months treatment) and 13 relapsers to interferon alfa 2a monotherapy (a dose of 3 to 6 million units three times per week for at least 20 weeks but not more than 18 months) were treated with the same dose of interferon alfa-2a used before (3 to 6 million units three times per week) and ribavirin (10 mg/ kg daily) for 6 months. In complete responders, interferon alfa-2a was administered for further 6 months at the same dose used before as monotherapy.RESULTS Seven (20.6%) of 34 non-responders stopped the combined therapy due to adverse events, including two patients with histological and clinical Child A cirrhosis. In 17/27 (63%)non-responders, the combined therapy was stopped after three months because of non-response. Ten of the 27 non-responders completed the 1;2-month treatment course. At a mean follow up of 28 months (16- 37 months)after the treatment, 4/10 (15%) previous non-responders still remained complete responders,All 13 previous relapsers completed the 12-month treatment course. At a mean follow up of 22months (9 - 36 months) after treatment, 6/13(46%) the previous relapsers were stillsustained complete responders.CONCLUSION Our treatment schedule of the combined therapy for 6 months of interferon alfa2a with a low dose of ribavirin (10 mg/kg/day)followed by 6 months of interferon alfa-2amonotherapy is able to induce a sustainedcomplete response rate in 15% of non-responders and 46% of relapsers with chronic hepatitis C virus-related liver diseases comparable to those obtained with the standarddoses of ribavirin 1000 - 1200 mg/day.Randomized prospective controlled trials using lower total amounts of ribavirin in combination with interferon should be performed.

Internet addiction and problematic Internet use: A systematic review of clinical research

AIM: To provide a comprehensive overview of clinical studies on the clinical picture of Internet-use related addictions from a holistic perspective. A literature search was conducted using the database Web of Science.METHODS: Over the last 15 years, the number of Internet users has increased by 1000%, and at the same time, research on addictive Internet use has proliferated. Internet addiction has not yet been understood very well, and research on its etiology and natural history is still in its infancy. In 2013, the American Psychiatric Association included Internet Gaming Disorder in the appendix of the updated version of the Diagnostic and Statistical Manual for Mental Disorders(DSM-5) as condition that requires further research prior to official inclusion in the main manual, with important repercussions for research and treatment. To date, reviews have focused on clinical and treatment studies of Internet addiction and Internet Gaming Disorder. This arguably limits the analysis to a specific diagnosis of a potential disorder that has not yet been officially recognised in the Western world, rather than a comprehensive and inclusive investigation of Internet-use related addictions(including problematic Internet use) more generally. RESULTS: The systematic literature review identified a total of 46 relevant studies. The included studies used clinical samples, and focused on characteristics of treatment seekers and online addiction treatment. Four main types of clinical research studies were identified, namely research involving(1) treatment seeker characteristics;(2) psychopharmacotherapy;(3) psychological therapy; and(4) combined treatment. CONCLUSION: A consensus regarding diagnostic criteria and measures is needed to improve reliability across studies and to develop effective and efficient treatment approaches for treatment seekers.

Randomized clinical study of five days apostrophe therapy with mebendazole compared to quinacrine in the treatment of symptomatic giardiasis in children

AIM： To compare the efficacy and safety of five days apostrophe therapy of mebendazole （MBZ） versus quinacrine （QC） on human giardiasis in children.METHODS： A clinical trial was carried out in paediatric patients （aged 5-15 years） with confirmed symptomatic G. duodenalis mono-infection. Patients were randomly assigned to receive either MBZ [200 mg taken three times per day GRID） （n = 61）] or QC [2 mg/kg bodyweight tid （n = 61）], both for five days. Follow-up faecal samples were obtained at 3, 5 and 7 d after the end of the treatment.RESULTS： Although the frequency of cure was higher for QC （83.6%） than for MBZ （78.7%）, the difference was not statistically significant （P 〉 0.05）. Adverse events were reported more in the QC group （P 〈 0.05）, all of them transient and self-limiting.CONCLUSION： Despite final cure rates ocurring lower than expected, the overall results of this study reconfirmed the efficacy of MBZ in giardiasis and also indicate that, although comparable to QC, at least in this setting the 5 d course of MBZ did not appear to improve the cure rates in this intestinal parasitic infection.

Gene transfection mediated by polyethyleneiminepolyethylene glycol nanocarrier prevents cisplatininduced spiral ganglion cell damage

Polyethyleneimine-polyethylene glycol （PEI-PEG）, a novel nanocarrier, has been used for trans- fection and gene therapy in a variety of cells. In our previous study, we successfully carried out PEI-PEG-mediated gene transfer in spiral ganglion cells. It remains unclear whether PEI-PEG could be used for gene therapy with X-linked inhibitor of apoptosis protein （XIAP） in the inner ear. In the present study, we performed PEI-PEG-mediated XIAP gene transfection in the cochlea of Sprague-Dawley rats, via scala tympani fenestration, before daily cisplatin injections. Audito- ry brainstem reflex tests demonstrated the protective effects of XIAP gene therapy on auditory function. Immunohistochemical staining revealed XIAP protein expression in the cytoplasm of cells in the spiral ganglion, the organ of Corti and the stria vascularis. Reverse transcription-PCR detected high levels of XIAP mRNA expression in the cochlea. The present findings suggest that PEI-PEG nanocarrier-mediated XIAP gene transfection results in XIAP expression in the cochlea, prevents damage to cochlear spiral ganglion cells, and protects hearing.

Analogous Systems Principles and Concepts of Traditional Chinese Medicine and Congruence Couple Therapy

This article explicates the analogous principles and concepts between traditional Chinese medicine(TCM)and congruence couple therapy(CCT).Although originating out of vastly different times and places,TCM and CCT share a view of health based on systems understanding to facilitate the interconnections of the parts of an organism rather than focusing on eliminating symptoms.Both approaches aim to release Qi(气)and vitality by removing blockages through adjusting the interactions,adaptation,and balance of multiple elements and Yin‑Yang energies.The goal is to liberate the Qi or life force through improved holistic balance and cooperation.While TCM focuses on interventions at the level of the body,CCT focuses on the attention,awareness,acknowledgement,and alignment of the four human dimensions consisting of the intrapsychic,interpersonal,intergenerational,and universal‑spiritual.In light of the current trend toward increasing mental,substance use,and neurological disorders,in particular among countries of middle and low income,dialogue to explore these compatibilities between TCM and CCT is conducive to the continuous evolution of TCM and Western therapies to address not only physical health but also the exigencies of contemporary addiction and mental health care within a mind–body relationship matrix.
