Clinical Characteristics and Potential Risk Factors Analysis of Liver Injury Related to Epimedii Folium Preparation / 中国实验方剂学杂志

ObjectiveThis paper aims to analyze the clinical characteristics and medication rationality of liver injury related to Epimedii Folium preparation （EP） and explore the possible risk factors of liver injury， so as to provide a reference for the safe clinical application of Epimedii Folium （EF）. MethodA retrospective analysis was conducted on liver injury cases related to EP from 2012 to 2016. ResultThe number of reported liver injury cases and the proportion of severe cases related to the use of EP show an increasing trend， indicating the objective existence of liver injury caused by EP. There are more cases of liver injury related to EP in women than in men， with an onset age range of 15-91 years old and a median onset age of 60 years old （median onset ages for men and women are 59 and 60 years old， respectively）. The time span from taking EP alone to the occurrence of liver injury is 1-386 days， with a median of 38 days. The time span from taking both EP and Western medicine to the occurrence of liver injury is 1-794 days， with a median of 34 days. EF-related liver injury preparations are mostly composed of traditional Chinese medicines that promote immunity and tonify the liver and kidney， indicating that immune stress in the body may be the mechanism of liver injury caused by the use of EP alone or in combination. There is no increasing trend of toxicity with time or dose in the liver injury caused by EP. By further exploring its risk factors， it is found that patients have unreasonable medication methods such as excessive dosage， repeated use， and multi-drug combination， which may also be one of the important risk factors for EF-related liver injury. ConclusionEP has a certain risk of liver injury and should be emphasized in clinical diagnosis and treatment. Immune stress may be the mechanism of liver injury caused by EP， and in clinical use， it is necessary to be vigilant about the risk of liver injury caused by unreasonable use and combined use with Western medicine.

Research progress in therapy drug monitoring of levetiracetam / 中国药房

Levetiracetam （LEV） is the second generation of broad-spectrum anti-epileptic drug. LEV has the advantages of rapid absorption， short half-life， precise efficacy， good tolerance and few drug interactions. In order to improve the clinical efficacy of LEV， and reduce the occurrence of adverse reactions， children， pregnant women， the elderly， and patients with renal insufficiency should receive therapeutic drug monitoring （TDM）. Clinically， the samples are usually plasma or serum， and the TDM methods are mostly immunoassay or chromatography. There is currently no consensus on the effective concentration range of LEV， and the correlation between plasma concentration and adverse reactions is also unclear. The main factors affecting LEV plasma concentration include age， pregnancy， and patient compliance. How to interpret TDM results and adjust dosage based on the results will be the focus of future work.

Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine（Part 5）： Retrieval and Synthesis of Key Information on Rational Drug Use / 中医杂志

Recommendations for Chinese patent medicine （CPM） based on key information on rational drug use are one of the important conditions for enhancing guideline enforceability as well as facilitating guideline implementation. In this study， we discussed in detail of the key information on the rational use of CPM in five aspects， which are dosage， drug discontinuation， drug-drug and drug-food interactions， safety and economy. Following the process of multi-source search， synthesis and prioritization， it is suggested to collect key information on the rational use of CPM from a multi-source search of drug instructions， policy documents， literature， and clinical experts' experiences. Then the searched information should be summarized and prioritized with the principle that taking drug instructions as the basis and other-sources information for check and supplementation. Finally， methodological recommendations for the retrieval and synthesis of key information on rational drug use in guideline recommendations has been formed.

Methodology for the Development of Clinical Practice Guideline for Chinese Patent Medicine（Part 1）： Development Status and Characteristics / 中医杂志

The irrational use of Chinese patent medicines （CPM） is becoming more and more prominent， which makes the demand for clinical practice guidelines of CPM gradually increase. In order to make domestic scholars understand the latest developments and existing problems of the CPM guidelines， and promote its development， this paper introduced the concept of CPM guidelines， summarized the characteristics of the two development modes， namely “taking CPM as the key” and “taking disease/syndrome as the key”， and analyzed the current methodological status of developing and reporting CPM guidelines. Based on the existed problems， three suggestions have been put forward to optimize the quality of CPM guidelines， which were clarifying the target users and scope of CPM guidelines， establishing an open and transparent mechanism of the personnel involvement and process steps， and formulating implementable and operable recommendations for the use of CPM.

The Role of Education and Demographic Factors in Condom Use among Male Drug Users in Malaysia

@#Introduction: The rising prevalence of human immunodeficiency virus (HIV) among people who inject drugs is a major public health issue. This study intends to explore education and demographic correlates of use of condoms among male drug users in Malaysia. Methods: Data were extracted from the Integrated Biological and Behavioral Surveillance Survey 2017. Pearson’s chi-square tests and a logistic regression were used to examine the associations between condom use and education, and demographic factors. Results: Only a small proportion of drug users used condoms (25.7%). Educational backgrounds, age, ethnicity and marital status were associated with condom use. The likelihood of using condoms was lower among less educated drug users (aOR: 0.308–0.339). There was an interaction effect of education and age on condom use (aOR: 0.116–0.308). Chinese (aOR: 3.117) and those of other ethnicities (aOR: 2.934) were more likely to use condoms when compared with Malays. Being married (aOR: 0.291) or divorced/widowed (aOR: 0.346) was associated with reduced odds of using condoms. Conclusion: Education and demographic factors play an important role in influencing the decisions of Malaysian drug users to use condoms. Therefore, HIV-preventive measures targeting drug users could benefit by paying special attention to these factors.

Cuidado em saúde ao adolescente em vulnerabilidade ao uso de drogas / Health care for adolescents who are susceptible to drug use

RESUMO Este artigo trata das adolescências, no plural, como construção histórico-social de um processo dinâmico, e do adolescente perante seus modos de vida e expressão em um contexto histórico-social e singular. Entende-se aqui que ações meramente prescritivas são insuficientes para responder às complexidades dos processos de adoecimento mental na sociedade contemporânea. Objetivou-se compreender o contexto das práticas de cuidado em saúde ao adolescente em vulnerabilidade, diante do uso de drogas, na dimensão das tensões dos campos de práticas do cuidado em saúde. Estudo descritivo exploratório de abordagem qualitativa, que realizou entrevistas com profissionais da área da saúde (Unidade Básica de Saúde e Centro de Atenção Psicossocial Infantojuvenil). Destacam-se as tensões no campo de práticas entre o modelo assistencial biomédico e de guerra às drogas versus o psicossocial/comunitário; redução de estigma; acesso; redução de danos e nos atendimentos individuais, bem como a importância de refletir e fomentar o processo de mudança da mentalidade diante do adoecimento mental, visando atualizar as formas de cuidar. Esse processo tem sido realizado conforme os princípios da Reforma Psiquiátrica Brasileira, com avanços e retrocessos que repercutem na atualização das práticas de cuidado em saúde mais alinhadas às propostas de ações psicossociais e redutoras de vulnerabilidade.

ABSTRACT This article deals with adolescences, in the plural, as a socio-historical construction of a dynamic process and with the experience of adolescents with their lifestyle and self-expression in a unique socio-historical context. It assumes that purely prescriptive measures are insufficient to address the complexity of mental illness processes in contemporary society. This study aims to understand the context of health care practices for vulnerable youth, particularly those involved in substance use, through the lens of tensions in health practice domains. This is an exploratory, descriptive study using a qualitative approach, with interviews conducted with health professionals (in Basic Health Unit and Psychosocial Care Center for Children and Adolescents). The study highlights the tensions within health practice between the biomedical model and the war on drugs and a community-based psychosocial approach; it underlines the need for reducing stigmatization, improving access, harm reduction, and individualized care. It also emphasizes the importance of considering and promoting a shift in mentality towards mental illness in order to develop care strategies. This process was carried out in line with the principles of the Brazilian Mental Health Reform, with advances and setbacks that affect the updating of health practices, which are more oriented towards proposals for psychosocial and vulnerability-reducing actions.

Suicide ideation and psychotropic recreational drug use by adolescents: a systematic review and meta-analysis

ABSTRACT BACKGROUND: Adolescence is characterized by complex and dynamic changes, often involving experimentation, including the use of psychotropic substances. Although it is well-established that recreational psychotropic drugs are associated with suicide ideation in adults, evidence of this association in adolescents remains limited. OBJECTIVE: To investigate the relationship between suicide ideation and psychotropic recreational drug use among adolescents. DESIGN AND SETTING: Systematic review with meta-analysis developed at Universidade Federal de Uberlândia (UFU) and Universidade Estadual de Campinas (UNICAMP), Brazil. METHODS: A search across eight electronic databases for observational studies, without language or publication year restrictions, was conducted. The Joanna Briggs Institute tool was used to assess the risk of bias. Random-effects meta-analyses and odds ratios were used to measure the effects. RESULTS: The search yielded 19,732 studies, of which 78 were included in the qualitative synthesis and 32 in the meta-analysis. The findings indicated that suicidal ideation was 1.96 times more likely (95% confidence interval, CI = 1.47; 2.61) for adolescents who used some drug recurrently and 3.32 times more likely (95%CI = 1.86; 5.93) among those who abused drugs. Additionally, adolescents who used cannabis were 1.57 times more likely (95%CI = 1.34; 1.84) to experience suicide ideation compared with non-users, while cocaine users had 2.57 times higher odds (95%CI = 1.47; 4.50). CONCLUSIONS: Psychotropic recreational drug use is associated with suicidal ideation among adolescents regardless of current or previous use, abuse, or type of substance used. SYSTEMATIC REVIEW REGISTRATION: Registered in the PROSPERO database under the identification number CRD42021232360. https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021232360.

Hepatitis B induced fulminant liver failure: A call for prevention

Acute fulminant hepatic failure is a condition in which a healthy liver deteriorates rapidly following an insult, resulting in the impairment of its synthetic functions. This condition is rare and is associated with high fatality rates. We report the case of a 19-year-old male who was brought to the emergency room in an unconscious state with jaundice and persistent fever for 2–3 weeks after recently commencing intravenous use of morphine. He was found to be hepatitis B surface antigen reactive, and his laboratory tests indicated severe liver dysfunction with elevated levels of serum bilirubin, aspartate transaminase, alanine transaminase, gamma-glutamyl transferase, and International normalized ratio. The patient was diagnosed with fulminant liver failure with coagulopathy and hepatic encephalopathy. The patient’s family was addressed and counseled regarding the urgent need for liver transplantation. However, due to a lack of funds and insurance, supportive treatment was the only option left. Despite all supportive measures, the patient expired within 48 h. This case highlights the importance of various socioeconomic issues involved with liver transplantation, as in a resource-limited setting, urgent transplantation seems nearly impossible. In addition, this case report raises certain ethical issues that need consideration, particularly in an injection drug use scenario. It also highlights the importance of addressing the rising issue of injection drug use among youth, particularly in the regions of Punjab.

Naltrexona em baixa dose (LDN): tendência de consumo nas capitais brasileiras e Distrito Federal, 2014-2020 / Low-dose naltrexone (LDN): consumption trend in Brazilian capitals and the Federal District, 2014-2020

Resumo Estudo ecológico com objetivo de determinar o consumo de naltrexona em baixa dose (LDN) nas 26 capitais brasileiras e Distrito Federal e acompanhar a tendência entre os anos de 2014 e 2020. A coleta de dados da dispensação de naltrexona manipulada, se deu por meio do Sistema Nacional de Gerenciamento de Produtos Controlados, publicizado em 2020, considerando-se baixa dose prescrições de até 5 mg. O cálculo dos coeficientes de dispensação utilizou as estimativas populacionais do Instituto Brasileiro de Pesquisa Geografia e Estatística. Utilizou-se análise estatística descritiva e de regressão generalizada de Prais-Winsten para a série temporal. As tendências observadas foram classificadas em crescentes, estáveis ou decrescentes, com intervalo de confiança de 95% e nível de significância de 5%. Os resultados demonstraram maiores coeficientes de consumo de LDN nas regiões Centro-Oeste, Sul e Sudeste e menores nas Norte e Nordeste. Observou-se dispensação de LDN crescente em 55,6% das capitais, estacionária em 44,4% e ausência de coeficientes decrescentes. Apesar das evidências limitadas quanto à farmacoterapia de LDN e da sua prescrição off-label, os dados demonstram que a prescrição, dispensação e consumo vem crescendo no Brasil, com ênfase nas regiões centro-sul do país.

Abstract The scope of this paper is an ecological study to determine the consumption of low-dose naltrexone (LDN) in the 26 Brazilian capitals and the Federal District and monitor the trend between the years 2014 to 2020. Data collection on the dispensation of manipulated naltrexone was done through the National Management System of Controlled Products, published in 2020, considering low-dose prescriptions of up to 5 mg. The calculation of the dispensation coefficients used the population estimates of the Brazilian Institute of Geography and Statistics. Descriptive statistical analysis and generalized Prais-Winsten regression analysis were used for the time series analysis. The trends observed were classified as increasing, stable, or decreasing, with a 95% confidence interval and 5% significance level. The results showed higher LDN consumption coefficients in the Mid-West, South and Southeast regions and lower coefficients in the North and Northeast. Increasing dispensation of LDN was observed in 55.6% of the capitals, being stationary in 44.4%, with no decreasing coefficients. Despite the limited evidence regarding LDN pharmacotherapy and its off-label prescription, the data show that prescription, dispensing, and consumption have been on the increase in Brazil, with emphasis on the central-south regions of the country.

AngioVac System for Infective Endocarditis: A New Treatment for an Old Disease

Three different patients presented to our institution with right-sided infective endocarditis (IE). All three were found to have vegetation on the tricuspid valve. These patients were started on appropriate antimicrobial therapy according to their blood cultures sensitivities. Despite this management, the patients� clinical status did not improve solely on antimicrobials. Surgery was, therefore, indicated to remove the vegetations. Traditionally, the appropriate management would have been invasive surgery. However, these patients were subjected to a novel treatment in our institution for right?sided IE: percutaneous mechanical vegetation debulking with an AngioVac system. After this procedure, all three patients� clinical status improved drastically. This new less invasive approach seems to offer the same results as the traditional invasive surgery, with faster recovery time. More comparative studies are needed to confirm this idea.

Cost-minimization analysis of drugs used for empirical treatment of urinary tract infection in a tertiary care hospital

Background: Urinary tract infections (UTIs) are one of the commonly encountered infections and a large number of drugs are indicated in UTI ranging from oral conventional drugs to most advanced injectable drugs. Cost-minimization analysis (CMA) is employed to project the least costly drug when two treatments are shown to be therapeutic equivalents. Aims and Objectives: This study aims to perform a CMA at a tertiary care center to determine the least expensive drug for UTI and to project a cheapest alternative from available options based on the results of CMA. Materials and Methods: This was a cross-sectional study conducted over duration of 3 months in the clinical departments on patients diagnosed to have UTI and prescribed empirical antimicrobial treatment. The approval of Institutional Ethics Committee was sought before beginning the study. Pattern of drug prescription and average cost incurred in the treatment of patients with empirical antimicrobial therapy was calculated. CMA included the projection of the least expensive drug based on average cost incurred per patient in outpatients and inpatients respectively. Results: A total of 59 patients of UTI given empirical treatment were included in the study. Fluoroquinolones and cephalosporins were commonly used drugs for empirical treatment of UTI. Nitrofurantoin (average cost of 11–14 Rs. per patient) can be projected as the cheapest drug for empirical treatment of UTI on outpatient basis as well as a drug to supplement injectables in indoor patients. Injectable ciprofloxacin can be projected as the most inexpensive alternative for empirical treatment of UTI in patients of the inpatient department. Conclusion: Nitrofurantoin for oral treatment and ciprofloxacin in injectable form are cheapest among available alternatives for empirical treatment of UTI. To prevent treatment failures and increase in cost of treatment, correlation of results of CMA with local antimicrobial sensitivity pattern is important.

Prevalence and predictors of depression among college going youth of Meghalaya: A cross-sectional study

Backgrounds: College years are characterized by transitioning from pre-adult to adulthood, a period of turmoil, adjusting to the new condition, separation from parental supervision, independence, and countering new things throughout everyday life. Depression and health-risk behaviors, including alcohol, tobacco, and illicit drug, are often found in college students, particularly during their first year. Aim: To study the prevalence and predictors of depression among college-going youth of Meghalaya, India. Materials and Methods: A cross-sectional community-based study has been undertaken to find the prevalence of depression, alcohol use, and drug use in college-going youth in Shillong, Meghalaya. A random sampling technique was used for the selection of colleges, and total enumeration was used for the selection of college-going students. A total of 358 respondents were selected for the present study. Permission from the college authority was obtained, and written informed consent was taken from the students. The participants have been explained the purpose of the study and the samples were selected voluntarily. The present study’s data were analyzed and interpreted using Statistical Package for Social Sciences version 20.0. Socio-demographic datasheet, Beck Depression Inventory-II, Hamilton Anxiety Rating Scale, Alcohol Use Disorder Identification Test, and drug abuse screening test were administered. Results: In the present study, 40.5% fall under the normal range of depression, while 38.3% had mild mood disturbance, 10.3% had borderline clinical depression, 9.7% had moderate depression, and severe depression was found in 1.1%. Alcohol use, drug use, and gender contribute significantly to the prediction of depression among college-going students ( F[5,19.551] = 855.3, P = 0.000) accounting for 21.7% variance. Conclusion: Our findings highlight the need for a college mental health program for early identification and screening of substance use and depression in college students.

Effects of plateau hypoxia on population pharmacokinetics and pharmacodynamics of metformin in patients with Type 2 diabetes / 中南大学学报(医学版)

OBJECTIVES@#Metformin is the basic drug for treating diabetes, and the plateau hypoxic environment is an important factor affecting the pharmacokinetics of metformin, but there have been no reports of metformin pharmacokinetic parameters in patients with diabetes mellitus type 2 (T2DM) in the high-altitude hypoxic environment. This study aims to investigate the effect of the hypoxic environment on the pharmacokinetics and assess the efficacy and safety of metformin administration in patients with Type 2 diabetes mellitus (T2DM).@*METHODS@#A total of 85 patients with T2DM taking metformin tablets in the plateau group (n=32, altitude: 1 500 m) and control group (n=53, altitude: 3 800 m) were enrolled according to the inclusion and exclusion criteria, and 172 blood samples were collected in the plateau group and the control Group. A ultra-performance liquid chromatography/tandem mass spectrometry (UFLC-MS/MS) method was established to determine the blood concentration of metformin, and Phoenix NLME software was used to establish a model of pharmacokinetics of metformin in the Chinese T2DM population. The efficacy and serious adverse effects of metformin were compared between the 2 groups.@*RESULTS@#The population pharmacokinetic modeling results showed that plateau hypoxia and age were the main covariates for model building, and the pharmacokinetic parameters were significantly different between the plateau and control groups (all P<0.05), including distribution volume (V), clearance (CL), elimination rate constant (Ke), half-life(T1/2), area under the curve (AUC), time to reach maximum concentration (Tmax). Compared with the control group, AUC was increased by 23.5%, Tmax and T1/2 were prolonged by 35.8% and 11.7%, respectively, and CL was decreased by 31.9% in the plateau group. The pharmacodynamic results showed that the hypoglycaemic effect of T2DM patients in the plateau group was similar to that in the control group, the concentration of lactic acid was higher in the plateau group than that in the control group, and the risk of lactic acidosis was increased after taking metformin in the plateau population.@*CONCLUSIONS@#Metformin metabolism is slowed down in T2DM patients in the hypoxic environment of the plateau; the glucose-lowering effect of the plateau is similar, and the attainment rate is low, the possibility of having serious adverse effects of lactic acidosis is higher in T2DM patients on the plateau than on the control one. It is probably suggested that patients with T2DM on the plateau can achieve glucose lowering effect by extending the interval between medication doses and enhancing medication education to improve patient compliance.

Establishment and application of evaluation criteria for clinical rational drug use of atosiban based on AHP-TOPSIS method / 中国药房

OBJECTIVE To establish evaluation criteria for rational drug use of atosiban in clinic， and to provide reference for rational drug use of atosiban in clinic. METHODS Based on the drug instructions of atosiban acetate injection and related guidelines， the experts of the Evaluation Group of Rational Drug Use formulated the evaluation criteria of rational drug use， including 5 primary indexes and 8 secondary indexes. The weight coefficients of secondary indexes were calculated by analytic hierarchy process （AHP）， and the use of atosiban acetate injection in 190 pregnant women from the Third Affiliated Hospital of Guangzhou Medical University （referred to as “our hospital”） was evaluated retrospectively by technique for order preference by similarity to an ideal solution （TOPSIS）. The evaluation results were divided into three levels including reasonable， basic reasonable and unreasonable application based on the relative approach degree. RESULTS Among 190 pregnant women， 49 （25.8%） were treated with atosiban reasonably， 39 （20.5%） were treated with atosiban basic reasonably， and 102 （53.7%） were treated with atosiban unreasonably. The evaluation results obtained by AHP-TOPSIS method were consistent with the actual situation in clinic. The main problems of the unreasonably use were super indications， unreasonable usage and dosage， over the course of treatment and the lack of proper economic consideration. CONCLUSIONS The rationality evaluation criteria of atosiban’s clinical application are established by AHP-TOPSIS method； the evaluation results obtained by this method are quantifiable， scientific and reliable. The unreasonable use of atosiban is common in our hospital， and the management should be strengthened in clinical application.

Mining and analysis of adverse drug event signals related to mepolizumab / 中国药房

OBJECTIVE To provide reference for rational clinical use of mepolizumab. METHODS The reporting odds ratio method and Bayesian confidence propagation neural network method were used to conduct signal mining and analysis of adverse drug event （ADE） reports related to mepolizumab in the United States Food and Drug Administration Adverse Event Reporting System from the first quarter of 2016 to the third quarter of 2022. RESULTS A total of 57 501 ADE reports were extracted with mepolizumab as the primary suspect drug， involving 16 358 patients. Among these reports， the proportion of males （23.51%） was lower than females （50.48%）. The reporting countries were primarily the United States （51.91%） and Canada （29.94%）. Consumers （71.18%） constituted the main reporting population. A total of 172 ADE-positive signals were identified， mainly involving 13 system organ classes such as the respiratory， thoracic and mediastinal disorders （41.63%）， as well as infectious and parasitic diseases （14.16%）. There were 60 high-risk signals， including 15 that were explicitly mentioned or related to adverse reactions in the drug instructions of mepolizumab and 45 signals （such as asthmatic crisis， sputum discoloured， purulent sputum， sleep disorder due to a general medical condition） were newly identified high-risk signals. Among them， 11 high-risk signals exhibited gender or age differences. CONCLUSIONS When clinically using mepolizumab， in addition to the adverse reactions mentioned in the drug instruction， special attention should also be given to changes in the nature of sputum， painful respiration， and sleep disorders.
