Clinical pharmacists’ involvement in carbapenem antibiotics management at Wenzhou Integrated Hospital

BACKGROUND Carbapenem antibiotics are a pivotal solution for severe infections,particularly in hospital settings.The emergence of carbapenem-resistant bacteria owing to the irrational and extensive use of carbapenems underscores the need for meticulous management and rational use.Clinical pharmacists,with their specialized training and extensive knowledge,play a substantial role in ensuring the judicious use of carbapenem.This study aimed to elucidate the patterns of carbapenem use and shed light on the integral role played by clinical pharmacists in managing and promoting the rational use of carbapenem antibiotics at Wenzhou Integrated Traditional Chinese and Western Medicine Hospital.AIM To analyze carbapenem use patterns in our hospital and role of clinical pharmacists in managing and promoting their rational use.METHODS We performed a retrospective analysis of carbapenem use at our hospital between January 2019 and December 2021.Several key indicators,including the drug utilization index,defined daily doses(DDDs),proportion of antimicrobial drug costs to total hospitalization expenses,antibiotic utilization density,and utilization rates in different clinical departments were comprehensively analyzed.RESULTS Between 2019 and 2021,there was a consistent decline in the consumption and sales of imipenem-cilastatin sodium,meropenem(0.3 g),and meropenem(0.5 g).Conversely,the DDDs of imipenem-cilastatin sodium for injection increased in 2020 and 2021 vs 2019,with a B/A value of 0.67,indicating a relatively higher drug cost.The DDDs of meropenem for injection(0.3 g)exhibited an overall upward trend,indicating an increasing clinical preference.However,the B/A values for 2020 and 2021 were both>1,suggesting a relatively lower drug cost.The DDDs of meropenem for injection(0.5 g)demonstrated a progressive increase annually and consistently ranked first,indicating a high clinical preference with a B/A value of 1,signifying good alignment between economic and social benefits.CONCLUSION Carbapenem use in our hospital was generally reasonable with a downward trend in consumption and sales over time.Clinical pharmacists play a pivotal role in promoting appropriate use of carbapenems.

Treatment and prevention of diabetes complicated with non-alcoholic fatty liver disease by integrated traditional Chinese and Western medicine

Today’s social economy and science and technology levels are developing rapidly.Type 2 diabetes mellitus(T2DM)is increasing in incidence,and T2DM promotes non-alcoholic fatty liver disease(NAFLD)through some mechanisms.The pathogenesis of T2DM and NAFLD is interconnected,interacted with,and promoted.While increasing the economic burden on patients,it also affects the quality and life of patients themselves.In the world,the current treatment methods include exercise and diet control,drugs(including sugar reduction,lipid-lowering drugs,etc.),weight loss surgery,etc.,but currently,researching drugs can only control the progress of the disease.At present,there is no drug for T2DM combined with NAFLD treatment.Therefore,it is necessary to find and study effective drugs for NAFLD.Based on the principle of“syndrome differentiation,”traditional Chinese medicine(TCM)played an important role in treating this disease.The theory of TCM believes that the cause of NAFLD is mostly diet disorders and imbalances in daily life,leading to liver Qi stagnation,spleen dysfunction,and liver and kidney deficiency,producing phlegm and stasis.During the treatment process,we must pay attention to the goal of phlegm turbidity,but also pay attention to the source of phlegm turbidity,strengthen the spleen and stomach,nourish the liver and kidney,and restore the physiological function of the body.The ingredients of Chinese medicine extracts have the effects of antagonist oxidation stress,protecting liver cells,improving fibrous soluble systems,and promoting lipid metabolism,thereby reducing inflammatory factors to release damage to liver cells.By combining the diagnosis of TCM syndromes with Western medical disease diagnosis,the model of disease diagnosis combined with syndrome differentiation can compensate for some of the limitations of TCM’s sole reliance on syndrome differentiation,allowing for a better grasp of the disease.In treatment,a dual approach using traditional Chinese and Western medicine can enhance efficacy and reduce toxicity,leveraging both complementary strengths.Chinese medicine explains its treatment of NAFLD from a macro and micro level,providing a safer and more effective method for treating the disease.

Impact of body mass index on adverse kidney events in diabetes mellitus patients: A systematic-review and meta-analysis

BACKGROUND The incidence of chronic kidney disease among patients with diabetes mellitus(DM)remains a global concern.Long-term obesity is known to possibly influence the development of type 2 diabetes mellitus.However,no previous meta-analysis has assessed the effects of body mass index(BMI)on adverse kidney events in patients with DM.AIM To determine the impact of BMI on adverse kidney events in patients with DM.METHODS A systematic literature search was performed on the PubMed,ISI Web of Science,Scopus,Ovid,Google Scholar,EMBASE,and BMJ databases.We included trials with the following characteristics:(1)Type of study:Prospective,retrospective,randomized,and non-randomized in design;(2)participants:Restricted to patients with DM aged≥18 years;(3)intervention:No intervention;and(4)kidney adverse events:Onset of diabetic kidney disease[estimated glomerular filtration rate(eGFR)of<60 mL/min/1.73 m2 and/or microalbuminuria value of≥30 mg/g Cr],serum creatinine increase of more than double the baseline or end-stage renal disease(eGFR<15 mL/min/1.73 m2 or dialysis),or death.RESULTS Overall,11 studies involving 801 patients with DM were included.High BMI(≥25 kg/m2)was significantly associated with higher blood pressure(BP)[systolic BP by 0.20,95%confidence interval(CI):0.15–0.25,P<0.00001;diastolic BP by 0.21 mmHg,95%CI:0.04–0.37,P=0.010],serum albumin,triglycerides[standard mean difference(SMD)=0.35,95%CI:0.29–0.41,P<0.00001],low-density lipoprotein(SMD=0.12,95%CI:0.04–0.20,P=0.030),and lower high-density lipoprotein(SMD=–0.36,95%CI:–0.51 to–0.21,P<0.00001)in patients with DM compared with those with low BMIs(<25 kg/m2).Our analysis showed that high BMI was associated with a higher risk ratio of adverse kidney events than low BMI(RR:1.22,95%CI:1.01–1.43,P=0.036).CONCLUSION The present analysis suggested that high BMI was a risk factor for adverse kidney events in patients with DM.

Implementation of gastrointestinal function protection in severe acute pancreatitis

Severe acute pancreatitis(SAP)is a serious systemic disease associated with strong local inflammatory reactions and serious systemic pathophysiological disorders caused by trypsin spillover.Patients with SAP are prone to exhibit gastrointestinal dysfunction.Meanwhile,gastrointestinal dysfunction further aggravates the systemic inflammatory response and metabolic abnormalities,resulting in a more critical condition of SAP.Gastrointestinal dysfunction is considered to be the“trigger”of multiple organ dysfunction syndrome[1].Thus,it is important to maintain gastrointestinal homeostasis in the treatment of SAP.

Medical imaging for the diagnosis,recurrence and metastasis evaluation of clear cell sarcoma

Clear cell sarcoma(CCS)of soft tissue is extremely rare,accounting for approximately 1%of all soft tissue tumours.It is very difficult to diagnose CCS based on clinical manifestations.Magnetic resonance imaging(MRI)provides highresolution images of soft tissues and pathological features such as mucus,necrosis,bleeding,and fat through high and low signals on T1 weighted image(T1WI)and T2 weighted image(T2WI).On the other hand,the paramagnetism of melanin in CCS shortens the relaxation time of T1 and T2,and high signal intensity on T1WI and low signal intensity on T2WI can be found.This is different from most other soft tissue sarcomas.At present,the treatment method for CCS is surgical resection.MRI can effectively display the tumour edge,extent of surrounding oedema,and extent of fat involvement,which is highly important for guiding surgical resection and predicting postoperative recurrence.As an invasive sarcoma,CCS has a high risk of metastasis.Regardless of the pathological condition of the resected tumour,MRI or computed tomography(CT)should be performed every 1-2 years to assess recurrence at the primary site and to screen for metastasis in the lungs,liver,and bones.If necessary,PET-CT can be performed to evaluate the overall condition of the patient.

Spatial transcriptomics reveals that metabolic characteristics define the tumor immunosuppression microenvironment via iCAF transformation in oral squamous cell carcinoma

Tumor progression is closely related to tumor tissue metabolism and reshaping of the microenvironment. Oral squamous cell carcinoma (OSCC), a representative hypoxic tumor, has a heterogeneous internal metabolic environment. To clarify the relationship between different metabolic regions and the tumor immune microenvironment (TME) in OSCC, Single cell (SC) and spatial transcriptomics (ST) sequencing of OSCC tissues were performed. The proportion of TME in the ST data was obtained through SPOTlight deconvolution using SC and GSE103322 data. The metabolic activity of each spot was calculated using scMetabolism,and k-means clustering was used to classify all spots into hyper-, normal-, or hypometabolic regions. CD4T cell infiltration and TGF-βexpression is higher in the hypermetabolic regions than in the others. Through CellPhoneDB and NicheNet cell-cell communication analysis, it was found that in the hypermetabolic region, fibroblasts can utilize the lactate produced by glycolysis of epithelial cells to transform into inflammatory cancer-associated fibroblasts (iCAFs), and the increased expression of HIF1A in iCAFs promotes the transcriptional expression of CXCL12. The secretion of CXCL12 recruits regulatory T cells (Tregs), leading to Treg infiltration and increased TGF-β secretion in the microenvironment and promotes the formation of a tumor immunosuppressive microenvironment. This study delineates the coordinate work axis of epithelial cells-iCAFs-Tregs in OSCC using SC, ST and TCGA bulk data, and highlights potential targets for therapy.

Therapeutic effect of Wendan Decoction combined with mosapride on gastroesophageal reflux disease after esophageal cancer surgery

BACKGROUND Gastroesophageal reflux disease(GERD)is a common complication of esophageal cancer surgery that can affect quality of life and increase the risk of esophageal stricture and anastomotic leakage.Wendan Decoction(WDD)is a traditional Chinese herbal formula used to treat various gastrointestinal disorders,such as gastritis,functional dyspepsia,and irritable bowel syndrome.Mosapride,a prokinetic agent,functions as a selective 5-hydroxytryptamine 4 agonist,enhancing gastrointestinal motility.AIM To evaluate the therapeutic effects of WDD combined with mosapride on GERD after esophageal cancer surgery.METHODS Eighty patients with GERD were randomly divided into treatment(receiving WDD combined with mosapride)and control(receiving mosapride alone)groups.The treatment was conducted from January 2021 to January 2023.The primary outcome was improved GERD symptoms as measured using the reflux disease questionnaire(RDQ).The secondary outcomes were improved esophageal motility(measured using esophageal manometry),gastric emptying(measured using gastric scintigraphy),and quality of life[measured via the Short Form-36(SF-36)Health Survey].RESULTS The treatment group showed a notably reduced RDQ score and improved esophageal motility parameters,such as lower esophageal sphincter pressure,peristaltic amplitude,and peristaltic velocity compared to the control group.The treatment group showed significantly higher gastric emptying rates and SF-36 scores(in both physical and mental domains)compared to the control group.No serious adverse effects were observed in either group.CONCLUSION WDD combined with mosapride is an effective and safe therapy for GERD after esophageal cancer surgery.It can improve GERD symptoms,esophageal motility,gastric emptying,and the quality of life of patients.Further studies with larger sample sizes and longer follow-up periods are required to confirm these findings.

Combination of comprehensive thermal care and detail-oriented nursing care in the operating room for managing gestational diabetes mellitus

BACKGROUND As the incidence of gestational diabetes mellitus(GDM)increases,its impact on cesarean sections has attracted widespread attention.Omni-directional,insulated care and detailed care are of great significance in this patient population,as they can effectively improve the quality of care in the operating room.AIM To explore the effect of the integrated use of comprehensive thermal insulation.METHODS Women with GDM who underwent cesarean sections at our hospital between April 2023 and February 2024 were included in this retrospective study.The participants were randomly allocated to two groups:The observation and control groups.An all-around thermal insulation nursing strategy,including preoperative,intraoperative,and postoperative temperature maintenance,was adopted.In addition,detailed nursing care measures,such as blood glucose monitoring,wound care,and psychological counseling,were implemented in the observation group.RESULTS Comparative observation revealed that all-around thermal insulation care can effectively prevent the incidence of maternal hypothermia caused by surgery,reduce the risk of infection,and promote blood circulation.The implementation of detailed care improved maternal satisfaction and reduced the incidence of complications via the appropriate management of fluctuations in the blood glucose levels and optimization of the nursing process before and after surgery according to the patient's characteristics.CONCLUSION The application of a combination of comprehensive thermal insulation and detailed nursing care improved the overall quality of perioperative care.

Soluble ST2:A Novel Biomarker for Diagnosis and Prognosis of Cardiovascular Disease

The increasing incidence of cardiovascular disease(CVD)is a significant global health concern,affecting millions of individuals each year.Accurate diagnosis of acute CVD poses a formidable challenge,as misdiagnosis can significantly decrease patient survival rates.Traditional biomarkers have played a vital role in the diagnosis and prognosis of CVDs,but they can be influenced by various factors,such as age,sex,and renal function.Soluble ST2(sST2)is a novel biomarker that is closely associated with different CVDs.Its low reference change value makes it suitable for continuous measurement,unaffected by age,kidney function,and other confounding factors,facilitating risk stratification of CVDs.Furthermore,the combination of sST2 with other biomarkers can enhance diagnostic accuracy and prognostic value.This review aims to provide a comprehensive overview of sST2,focusing on its diagnostic and prognostic value as a myocardial marker for different types of CVDs and discussing the current limitations of sST2.

Effect and safety of ripretinib in the treatment of advanced gastrointestinal stromal tumor:A systematic review and metaanalysis

BACKGROUND Imatinib(IMA)has received approval as the primary treatment for gastrointestinal stromal tumors(GIST).Nonetheless,approximately half of the patients with advanced GIST show disease advancement following IMA treatment.Presently,the efficacy of secondary and tertiary medications in addressing various GIST secondary mutations is somewhat restricted.Consequently,there is a significant medical demand for the creation of kinase inhibitors that extensively block secondary drug-resistant mutations in advanced GIST.Ripretinib(RPT)is a new,switch-control tyrosine kinase inhibitors that can suppress different mutations of KIT and PDGFRA via a dual mechanism of action.AIM To investigate the literature on RPT to assess an effective,safe,and successful treatment strategy against advanced GIST.METHODS The present systematic review and meta-analysis was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.PubMed,Embase,Cochrane,Web of Science and ClinicalTrials.gov databases were screened from January 1,2003 to May 1,2024.RESULTS A total of 4 studies were included,with a total of 507 patients enrolled.The objective response rate(ORR)of the RPT-treated advanced GIST was 17%(95%CI:0.11-0.27),while the disease control rate(DCR)was 66%(95%CI:0.59-0.73).The overall occurrence of adverse events with varying degrees was 97%(95%CI:0.93-1),whereas that of grade≥3 adverse reactions was 42%(95%CI:0.28-0.63).The sensitivity analysis revealed that omitting some studies did not yield statistically notable variances in the aggregate data regarding the ORR,DCR,and the occurrence of adverse events of grade 3 or higher.The publication bias was absent because no significant asymmetry was observed in Begg’s funnel plot in all studies.CONCLUSION RPT has favorable efficacy profiles in GIST patients,but the adverse reactions are obvious,and patient management needs to be strengthened to achieve better safety and tolerability.

Management of monogenic diabetes in pregnancy:A narrative review

Pregnancy in women with monogenic diabetes is potentially complex,with significant implications for both maternal and fetal health.Among these,maturity-onset diabetes of the young(MODY)stands out as a prevalent monogenic diabetes subtype frequently encountered in clinical practice.Each subtype of MODY requires a distinct approach tailored to the pregnancy,diverging from management strategies in non-pregnant individuals.Glucokinase MODY(GCK-MODY)typically does not require treatment outside of pregnancy,but special considerations arise when a woman with GCK-MODY becomes pregnant.The glycemic targets in GCK-MODY pregnancies are not exclusively dictated by the maternal/paternal MODY genotype but are also influenced by the genotype of the developing fetus.During pregnancy,the choice between sulfonylurea or insulin for treating hepatocyte nuclear factor 1-alpha(HNF1A)-MODY and HNF4A-MODY depends on the mother’s specific circumstances and the available expertise.Management of other rarer MODY subtypes is individu-alized,with decisions made on a case-by-case basis.Therefore,a collaborative approach involving expert diabetes and obstetric teams is crucial for the compre-hensive management of MODY pregnancies.

Changes in postoperative depression and anxiety and their relationship with recovery from femoral head necrosis:A longitudinal study

BACKGROUND Femoral head necrosis(FHN)can significantly affect patients'psychological well-being and functional outcomes.However,the long-term relationship between postoperative depression,anxiety,and functional recovery in patients with FHN remains unclear.AIM To investigate the dynamic changes in postoperative depression and anxiety and their relationship with functional recovery in patients with FHN for 3 years.METHODS Ninety-three patients with FHN who underwent surgical treatment in March 2020 to 2023 were enrolled in this longitudinal study.Depression and anxiety status were assessed using the hospital anxiety and depression scale(HADS)at baseline,6 months,1,2,and 3 years postoperatively.Functional recovery was evaluated using the Harris hip score(HHS).The dynamic changes in HADS and HHS were analyzed using repeated measures ANOVA;the relationship between depre-ssion/anxiety status and functional recovery was examined using Pearson’s correlation analysis.RESULTS The mean HADS-depression(HADS-D)and HADS-anxiety(HADS-A)scores significantly improved over time(P<0.001).The prevalence of depression and anxiety decreased from 36.6%and 41.9%at baseline to 10.8%and 12.9%,respectively,at 3 years postoperatively.The mean HHS increased sig-nificantly from 52.3±10.5 at baseline to 88.1±7.2 at 3 years postoperatively(P<0.001).Significant negative correl-ations were found between HADS-D/HADS-A scores and HHS at all time points(P<0.05).CONCLUSION The severity of depression and anxiety negatively correlated with functional recovery,highlighting the importance of psychological interventions in the management of patients with FHN.

Objective: This study aims to evaluate the safety and efficacy of PETD combined with nerve root water imaging of MRI for the treatment of lumbar disc herniation. Methods: A retrospective review was performed on 62 patients with lumbar disc herniation from March 2019 to March 2021. The study included an experimental group of 30 patients and a control group of 32 patients. The experimental group underwent PETD combined with nerve root water imaging of MRI, while the control group received traditional PETD treatment. The visual analogue scoring method (VAS score), and JOA lumbar spine function score before and after surgery were compared between the two groups, and efficacy was assessed and compared using the MacNab score. Results: The mean operation time was significantly reduced in the experimental group (56.43 &#177;10.40 minutes) compared to the control group (65.69 &#177;14.12 minutes). The VAS score was compared between the two groups with preoperative (p = 0.624), one month after surgery (p = 0.325), three months after surgery (p = 0.676), one year after surgery (p = 0.341);The JOA score was compared between the two groups with preoperative (p = 0.961), one month after the surgery (p = 0.266), three months after surgery (p = 0.185), one year after surgery (p = 0.870), they were no significant statistical difference;The efficacy evaluation of the last follow-up Macnab showed that all the 30 patients in the experimental group were excellent, 31 of 32 patients in the control group were excellent, 1 case was good;There was no statistical difference in the comparison between the two groups (p > 0.05). Conclusion: The study concludes that the combined approach of PETD with nerve root water imaging of MRI is a safe, effective, and more efficient alternative to conventional PETD for treating lumbar disc herniation.

Research progress on the role of adipocyte exosomes in cancer progression

Exosomes,minute vesicles ubiquitously released by diverse cell types,serve as critical mediators in intercellular communication.Their pathophysiological relevance,especially in malignancies,has garnered significant attention.A meticulous exploration of the exosomal impact on cancer development has unveiled avenues for innovative and clinically valuable techniques.The cargo conveyed by exosomes exerts transformative effects on both local and distant microenvironments,thereby influencing a broad spectrum of biological responses in recipient cells.These membranebound extracellular vesicles(EVs)play a pivotal role in delivering bioactive molecules among cells and organs.Cellular and biological processes in recipient cells,ranging from stromal cell reprogramming to immunological responses,extracellular matrix formation,and modulation of cancer cell activation,expansion,and metastasis,are subject to exosome-mediated cell-to-cell communication.Moreover,exosomes have been implicated in endowing cancer cells with resistance to treatment.Extensive research has explored the potential of exosomes as therapeutic targets and diagnostic indicators.This comprehensive review seeks to provide an in-depth understanding of the pivotal components and roles of exosomes in tumorigenesis,growth,progression,and therapeutic responses.The insights into the multifaceted involvement of exosomes in malignant cancers are essential for the scientific community,fostering the development of novel therapeutic and diagnostic strategies in the relentless pursuit of cancer.

Continuous glucose monitoring metrics in pregnancy with type 1 diabetes mellitus

Managing diabetes during pregnancy is challenging,given the significant risk it poses for both maternal and foetal health outcomes.While traditional methods involve capillary self-monitoring of blood glucose level monitoring and periodic HbA1c tests,the advent of continuous glucose monitoring(CGM)systems has revolutionized the approach.These devices offer a safe and reliable means of tracking glucose levels in real-time,benefiting both women with diabetes during pregnancy and the healthcare providers.Moreover,CGM systems have shown a low rate of side effects and high feasibility when used in pregnancies complicated by diabetes,especially when paired with continuous subcutaneous insulin infusion pump as hybrid closed loop device.Such a combined approach has been demonstrated to improve overall blood sugar control,lessen the occurrence of preeclampsia and neonatal hypoglycaemia,and minimize the duration of neonatal intensive care unit stays.This paper aims to offer a comprehensive evaluation of CGM metrics specifically tailored for pregnancies impacted by type 1 diabetes mellitus.

Non-invasive diagnosis of advanced fibrosis and cirrhosis

Liver cirrhosis is a common and growing public health problem globally.The diagnosis of cirrhosis portends an increased risk of morbidity and mortality.Liver biopsy is considered the gold standard for diagnosis of cirrhosis and staging of fibrosis.However,despite its universal use,liver biopsy is an invasive and inaccurate gold standard with numerous drawbacks.In order to overcome the limitations of liver biopsy,a number of non-invasive techniques have been investigated for the assessment of cirrhosis.This review will focus on currently available non-invasive markers of cirrhosis.The evidence behind the use of these markers will be highlighted,along with an assessment of diagnostic accuracy and performance characteristics of each test.Non-invasive markers of cirrhosis can be radiologic or serum-based.Radiologic techniques based on ultrasound,magnetic resonance imaging and elastography have been used to assess liver fibrosis.Serum-based biomarkers of cirrhosis have also been developed.These are broadly classified into indirect and direct markers.Indirect biomarkers reflect liver function,which may decline with the onset of cirrhosis.Direct biomarkers,reflect extracellular matrix turnover,and include molecules involved in hepatic fibrogenesis.On the whole,radiologic and serum markers of fibrosis correlate well with biopsy scores,especially when excluding cirrhosis or excluding fibrosis.This feature is certainly clinically useful,and avoids liver biopsy in many cases.

Metastatic colorectal cancer-past,progress and future

The clinical management of metastatic （stage IV） colorectal cancer （CRC） is a common challenge faced by surgeons and physicians. The last decade has seen exciting developments in the management of CRC, with significant improvements in prognosis for patients diagnosed with stage IV disease. Treatment options have expanded from 5-fluorouracil alone to a range of pharmaceutical and interventional therapies, improving survival, and providing a cure in selected cases. Enhanced understanding of the biologic pathways most important in colorectal carcinogenesis has led to a new generation of drugs showing promise in advanced disease. It is hoped that in the near future the treatment paradigm of metastatic CRC will be analogous to that of a chronic illness, rather than a rapidly terminal condition. This overview discusses the epidemiology of advanced CRC and currently available therapeutic options including medical, surgical, ablative and novel modalities in the management of metastatic colorectal cancer.

Adjuvant therapies for colorectal cancer

The management of colon and rectal cancer has changed dramatically over the last 25 years. The use of adjuvant therapies has become standard practice in locally advanced （stage M and selected stage 11） colorectal cancer. Improved surgical techniques, chemotherapeutics and radiotherapy are resulting in higher cure rates and the development of agents targeting proliferative and angiogenic pathways offer further promise. Here we explore risk factors for local and distant recurrence after resection of colon and rectal cancer, and the role of adjuvant treatments. Discussion will focus on the evidence base for adjuvant therapies utilised in colorectal cancer, and the treatment of sub-groups such as the elderly and stage 11 disease. The role of adjuvant radiotherapy in rectal cancer in reduction of recurrence will be explored and the role and optimal methods for surveillance post-curative resection with or without adjuvant therapy will also be addressed.
