Vivencias y estrategias comunitarias de manejo del riesgo dentro de las prácticas chemsex: un estudio cualitativo / Community experiences and strategies of risk management within chemsex practices: a qualitative study

Resumen El auge en el estudio del uso sexualizado de drogas entre hombres gais, bisexuales u otros hombres que tienen sexo con hombres (HSH), conocido como chemsex, ha generado una multiplicidad de datos que contribuyen a su problematización en tanto cuestión de salud pública a través del vínculo con el VIH y las adicciones. El estudio de estas prácticas, desde un paradigma biomédico, se ha centrado en el riesgo y ha contribuido a su reducción como fenómeno único y cuantificable. Este estudio tiene como objetivo explorar la vivencia del riesgo en el transcurso de las prácticas, para conocer qué estrategias de manejo emplean frente a éste y de qué manera son generadas. Se realizaron entrevistas semiestructuradas a cinco practicantes de chemsex en el Área Metropolitana de Barcelona y, posteriormente se aplicó un análisis temático. Los hallazgos muestran cómo estos hombres detectan, asumen y enfrentan los riesgos presentes en estas prácticas, donde toman relevancia el tipo de relaciones que allí se dan y el círculo social del que disponen. Este estudio destaca también la creación de estrategias basadas en la experiencia y cómo la transmisión de estos saberes entre participantes facilita la toma de decisiones y el manejo del riesgo.

Abstract The rise in the study of sexualised drug use among gay, bisexual and other men who have sex with men (MSM), known as chemsex, has generated a multiplicity of data that contribute to its problematisation as a public health issue through the link with HIV and addictions. The study of these practices, from a biomedical paradigm, has focused on risk and has contributed to its reduction as a unique and quantifiable phenomenon. This study aims to explore the experience of risk in the course of the practices, to find out what management strategies they employ in the face of risk and how they are generated. Semi-structured interviews were conducted with five chemsex practitioners in the Metropolitan Area of Barcelona and, subsequently, a thematic analysis was applied. The findings show how these men detect, assume and confront the risks present in these practices, where the type of relationships that take place and the social circle available to them are relevant. This study also highlights the creation of strategies based on experience and how the transmission of this knowledge among participants facilitates decision-making and risk management.

Prescrição de benzodiazepínicos em Unidades Básicas de Saúde em uma comunidade com alta vulnerabilidade social / Prescription of benzodiazepines in Health Centers in a community with high social vulnerability

RESUMO Os benzodiazepínicos, medicamentos mais prescritos no mundo, são extremamente úteis no manejo de patologias relativas ao sistema nervoso central, porém, nem sempre sua prescrição está relacionada com uma patologia. Este estudo buscou identificar os fatores influenciadores na prescrição de benzodiazepínicos na Atenção Básica do Sistema Único de Saúde e suas consequências, em uma região com alta vulnerabilidade social. Foram utilizados os princípios de um estudo qualitativo com amostra intencional de médicos prescritores construída com a ajuda dos Informantes-Chave e com tamanho (n = 10) definido pelo princípio da saturação teórica. A coleta de dados ocorreu mediante entrevistas semiestruturadas nas unidades básicas onde os profissionais atuavam. Os temas identificados relativos aos motivos da prescrição foram: relativos ao paciente (demanda do paciente; problemas sociais); relativos ao medicamento (dependência); relativos ao prescritor (uso irracional). A prescrição do benzodiazepínico deu-se devido às baixas condições sociais dos usuários nessa região e as consequências dessa conjuntura (vulnerabilidade social, problemas angustiantes de difícil resolução). Educação permanente para profissionais, ações interprofissionais e integralidade do cuidado foram demandas dos profissionais. O problema extrapola a ação do médico, e são sugeridas políticas públicas que garantam, às populações com essas características, acesso a saúde, trabalho e educação.

ABSTRACT Benzodiazepines, the most prescribed medications in the world, are extremely useful in managing conditions related to the central nervous system, however, their prescription is not always related to a pathology. This study sought to identify the factors influencing the prescription of benzodiazepines in Primary Care of the Unified Health System and their consequences, in a region with high social vulnerability. The principles of a qualitative study with intentional sampling of prescribing physicians were used, constructed with the help of Key Informants and with a size (N=10) defined by the principle of theoretical saturation. Collection took place through semi-structured interviews in the basic units where the professionals worked. The themes identified regarding the reasons for prescription were Patient-related (patient demand; social problems); Relating to medication (dependence); Relative to the prescriber (irrational use). The prescription of benzodiazepine was due to the low social conditions of users in this region and the consequences of this situation (social vulnerability, distressing problems with difficult resolution). Continuous education for professionals, interprofessional actions, and comprehensive care were demands of the professionals. The problem goes beyond the doctor's scope of action, and public policies that guarantee such populations access to health, work, and education are suggested.

Deprescribing psychotropic drugs in a geriatric psychiatry outpatient clinic

Objective: To describe the psychotropic drug deprescription process in older patients of a geriatric psychiatry outpatient clinic. Methods: We conducted a quasi-experimental study of people aged ≥ 60 years who were treated at Hospital São Lucas' Geriatric Psychiatry Outpatient Clinic, which is affiliated with Pontifícia Universidade Católica do Rio Grande do Sul, Brazil. Data on 150 older people were collected from March 2021 to August 2022 and were evaluated by the pharmacists. The inclusion criteria were age ≥ 60 years, being a patient of the hospital's Geriatric Psychiatry Outpatient Clinic, use of at least one psychotropic drug, and agreeing to participate in the study. Those unable to report their medications and those who only came to the first appointment were excluded. Results: Overall, deprescription of at least one psychotropic drug was indicated in 61.3% (n = 92) of the participants, and it was effectively implemented in 68.5% (n = 63) of this group. Deprescribing, which was more frequent in the youngest age group (60­69 years) (p = 0.049), was indicated for 37.4% (n = 136) of psychotropic drugs, 67.6% (n = 92) of which were effectively deprescribed. The main classes indicated for deprescription were hypnotics and sedatives (90.0%; n = 18) and anxiolytics (73.3%; n = 11). Conclusions: At least 1 psychotropic drug was indicated for deprescription in the majority of the patients, and in most cases it was effectively implemented. One-third of the prescribed psychotropic drugs were indicated for deprescription, and more than half were successfully deprescribed. (AU)

O uso de drogas e seus efeitos na cavidade oral

Objetivos: Descrever as principais manifestações bucais associadas ao uso das drogas lícitas e ilícitas mais utilizadas atualmente, bem como os cuidados que devem ser tomados durante o atendimento odontológico desses pacientes. Revisão de literatura: Na revisão foi abordada a classificação das substâncias químicas, as principais manifestações orais e os cuidados que o cirurgião-dentista deve ter durante o atendimento odontológico. As substâncias descritas foram álcool, tabaco, benzodiazepínicos, maconha, anfetaminas e cocaína/crack. As complicações de saúde bucal associadas ao abuso de drogas podem resultar da exposição direta dos tecidos orais às drogas durante o fumo ou ingestão, da interação biológica das drogas com a fisiologia normal da cavidade oral e dos efeitos das drogas na função cerebral que resultam em um espectro de comportamentos de dependência, como comportamento de risco, falta de higiene e descuido. Considerações finais: O consumo de substâncias psicoativas, seja a curto ou longo prazo, pode desencadear consequências, tanto na saúde geral como na saúde bucal do usuário. Sob essa perspectiva, o cirurgião-dentista deve estar ciente das manifestações orais e sistêmicas causadas pelas substâncias psicoativas e estar capacitado para diagnosticar, tratar ou também encaminhar o usuário, se necessário, visando um cuidado integral e multiprofissional.

Objective: to describe the main oral manifestations associated with the use of the most commonly used licit and illicit drugs today, as well as the care that should be taken during the dental care of these patients. Literature review: The review covered the classification of chemical substances, the main oral manifestations and the care that dentist should take during dental care. The substances described were alcohol, tobacco, benzodiazepines, marijuana, amphetamines and cocaine/crack. Oral health complications associated with drug abuse can result from direct exposure of oral tissues to drugs during smoking or ingestion, from the biological interaction of drugs with the normal physiology of the oral cavity, and from the effects of drugs on brain function that result in a spectrum of addictive behaviors, such as risk behavior, poor hygiene and carelessness. Final considerations: The consumption of psychoactive substances, whether in the short or long term, can have consequences for both the general health and the oral health of the user. From this perspective, the dentist must be aware of the oral and systemic manifestations caused by psychoactive substances and be able to diagnose, treat or also refer the user, if necessary, aiming for comprehensive, multi-professional care.

Research progress on the antitumor effects of platinum-based chemo-immunotherapies / 中国药科大学学报

@#Abstract: As potential immunomodulators, platinum-based drugs could trigger immunogenic cell death (ICD). Hence, combination of platinum-based chemotherapy and immunotherapy could have better synergistic anticancer effect. Pt(II)-based drugs are the most common chemotherapeutic agents in cancer treatment yet with limited clinical application due to their toxic side-effects and drug resistance. Pt(IV) complexes have been widely investigated in the past decades due to their kinetic inertness and unique mechanisms . This article summarizes the progress in the pharmacological activities and mechanisms of Pt(IV) antitumor complexes via introducing different immunomodulators into chemotherapeutic agents in literature over recent years and highlights the potential targets and molecular signaling pathways so as to provide some reference for further development and potential clinical application of platinum-based chemo-immunotherapeutic agents.

Hematological Indicators of Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency in Malaria-Infected Individuals

@#Introduction: Malaria, a life-threatening infectious disease caused by Plasmodium parasites, continues to be a major global health concern, particularly in regions with high transmission rates. This retrospective cohort study aimed to investigate the hematological indicators of G6PD deficiency in individuals infected with malaria. The study utilized medical records and laboratory test results to analyze the hematological parameters and markers in individuals with confirmed malaria and G6PD deficiency. Methods: Data were collected from the laboratory unit of Mosul Teaching Hospitals in Ninevah Province, Iraq, from March 2021 to November 2022. The study population consisted of individuals diagnosed with malaria and with available G6PD deficiency test results. G6PD deficiency was determined by measuring the G6PD enzyme activity in the patient’s blood. Hematological parameters, including complete blood counts, platelet counts, and red blood cell indices, were recorded using a laboratory information system. Results: The study population exhibited a relatively low prevalence of G6PD deficiency, with no significant differences observed in age or gender distribution between individuals with and without G6PD deficiency. The distribution of malaria types did not differ significantly between the two groups. However, patients with G6PD deficiency showed a significantly higher monocyte count, indicating a potential association between G6PD deficiency and altered monocyte response during malaria infection. The clinical significance of this finding requires further investigation. Conclusion: This study sheds light on the hematological indicators of G6PD deficiency in individuals infected with malaria. The findings suggest a potential relationship between G6PD deficiency and altered monocyte response during malaria infection.

Analysis of information labeling in instructions of antitussive and expectorant drugs in 34 children’s medical institutions / 中国药房

OBJECTIVE To understand the information labeling of children’s medication in the instructions of antitussive and expectorant drugs commonly used in children’s medical institutions， analyze the existing problems， and propose relevant suggestions. METHODS The instructions for 100 antitussive and expectorant drugs commonly used in 20 tertiary children’s hospitals （centers） and 14 maternal and child health hospitals （centers） with regional representativeness in China were collected， and the information labeling of children’s medication in the instructions was investigated and analyzed. RESULTS There were only 7 kinds of antitussive and expectorant drugs for children， and the others were non-specific drugs for children. Among antitussive and expectorant drugs， tablets accounted for 18.00%， injections for 18.00%， and capsules for 4.00%. Among 100 antitussive and expectorant drugs， 72 （72.00%） labeled the usage and dosage for children， 63 （63.00%） labeled the medication items for children， 59 （59.00%） indicated the information of children in the precautions， and pharmacokinetic parameters for children were absent. Compared with imported antitussive and expectorant drugs or the drugs manufactured by joint ventures， there were many missing labeling of medication information for children with Chinese drugs. Among 63 kinds of drug instructions labeled with medication items for children， various instructions information had little guiding significance. CONCLUSIONS There is a lack of labeling in the instructions of antitussive and expectorant drugs for children， and the proportion of special drugs for children remains low. Pediatric drug information in the instructions has little guiding significance for pediatric medication. Relevant departments should further promote the completeness of pediatric medication information in the instructions of antitussive and expectorant drugs to ensure the rational use of children’s medication.

Traditional Chinese Medicine in Treatment of Constipation Based on 5-HT Signaling Pathway： A Review / 中国实验方剂学杂志

Chronic constipation （CC） is one of the most common functional gastrointestinal diseases. At present， the overall therapeutic effect of CC is still not satisfactory worldwide， which seriously affects the quality of life and social function of patients. The etiology and pathophysiological mechanism of constipation are still unclear. It involves comprehensive factors such as heredity， social psychology， diet， intestinal flora imbalance， intestinal motility disorder， visceral sensitivity change， pelvic floor muscle group dysfunction and enteric nervous system （ENS） disorder. Among them， the abnormal factors of the brain-gut-microbiome axis are particularly significant. The brain-gut-microbiome axis is a complex network of interactions between the intestine and the brain， integrating and coordinating the physiological functions and pathological processes of the gastrointestinal tract. Microorganisms in the intestinal lumen play an important role in it， and can communicate with the intestinal tract and the central nervous system through nerve， endocrine and immune pathways. As a key brain-gut peptide in the regulation pathway of the brain-gut-microbiome axis， 5-hydroxytryptamine （5-HT） is involved in the regulation of gastrointestinal motility， sensation and secretion. The abnormal conduction of the 5-HT signaling pathway is closely related to the occurrence and development of constipation. Traditional Chinese medicine（TCM） is a unique precious resource in China， which has good curative effects and safety. In recent years， it has received extensive attention in the treatment of constipation. TCM and active ingredients， acupuncture and massage specifically regulate 5-HT signal transmission， so that the expressions of related molecules tend to be suitable for individual disease state levels to effectively improve constipation symptoms， with unique advantages. Therefore， this study used ''constipation''， ''intestinal flora''， ''5-HT''， and ''traditional Chinese medicine'' as the keywords to search PubMed， China National Knowledge Infrastructure （CNKI） and other literature databases. The correlation between 5-HT and constipation as well as brain-gut-microbiome axis and the research progress of TCM intervention in the 5-HT signaling pathway in the treatment of constipation were reviewed in order to explore the potential therapeutic value of 5-HT system in this disease and provide references for subsequent research.

Effect of Terpenes on the enhancement of skin permeation of lipophilic drugs: A systematic review

Objectives@#The stratum corneum (SC) remains an obstacle to the passage of drugs applied topically. Several investigations have focused on enhancing the penetration of drugs through the SC by integrating permeation enhancers (PE) into the drug formulation. Terpenes are among the PE utilized in formulations and are categorized by the regulatory bodies as generally recognized as safe (GRAS). This study aimed to comparatively analyze the skin permeation enhancing effect of terpenes on lipophilic drugs. @*Methods@#The present study reviewed the effects of terpenes on the permeation of lipophilic small-molecule drugs through the skin using original research published between 2000 - 2022 retrieved from PubMed®. The search phrase used was (lipophilic drug) AND (terpene) AND (permeation enhancer). @*Results@#Terpenes increase the percutaneous permeation of lipophilic small molecule drugs by 1.06 – 256.80-fold. Linear correlation analysis of terpenes’ cLog P with enhancement ratio (ER) revealed moderate and strong positive correlations in pig skin (r = 0.21) and mouse skin (r = 0.27), and rat skin (r = 0.41) and human skin (r = 0.67), respectively. Drug cLog P is a poor (r = -0.06) predictor of permeation enhancement. Terpenes with cLog P higher than 2.40 had ER greater than 10. Higher ERs (>30) were recorded for nerolidol, carvacrol, borneol, terpineol, limonene, menthone, pulegone, and menthol among the terpene-chemical penetration enhancers. @*Conclusion@#cLog P of terpene-based chemical permeation enhancers (CPE) is strongly correlated with ER of lipophilic drugs across human skin. Non-polar groups in terpenes and hydrogen bond interactions by terpenes with SC lipid enhance cutaneous drug penetration of lipophilic drugs.

Research progress of antineoplastic drugs targeting platelets / 中国药理学通报

Platelets have long been recognized as key players in hemostasis and thrombosis; however, there is growing evidence that they are also involved in cancer. Preclinical and clinical studies have shown that platelets can promote tumorigenesis and metastasis through various crosstalks between platelets and cancer cells. Platelets play an active role in all stages of tumorigenesis, including tumor growth, tumor cell extravasation, and metastasis. In addition, thrombocytosis in cancer patients is associated with poor patient survival. Platelets are also well-placed to coordinate local and distant tumor-host interactions due to the a- bundance of microparticles and exosomes. Therefore, antitumor drugs targeting platelets have great development and application prospects. The following will review the research progress of anti-tumor drugs targeting platelets.

Advances in relationship between pyroptosis and pulmonary arterial hypertension and therapeutic drugs / 中国药理学通报

Pyroptosis is the programmed death of cells accompanied by an inflammatory response and is widely involved in the development of a variety of diseases, such as infectious diseases, cardiovascular diseases, and neurodegeneration. It has been shown that cellular scorching is involved in the pathogenesis of pulmonary arterial hypertension ( PAH) in cardiovascular diseases. Patients with PAH have perivascular inflammatory infiltrates in lungs, pulmonary vasculopathy exists in an extremely inflam-matory microenvironment, and pro-inflammatory factors in cellular scorching drive pulmonary vascular remodelling in PAH patients. This article reviews the role of cellular scorch in the pathogenesis of PAH and the related research on drugs for the treatment of PAH, with the aim of providing new ideas for clinical treatment of PAH.

Brain Targeted Strategies of Oligonucleotide Drug for Aging-associated Diseases Therapy / 生物化学与生物物理进展

Oligonucleotide drugs have experienced accelerated development in the past 10 years, and some of them have been used in clinical treatment. Because of its convenient design, flexible sequence, and high specificity, it is expected to solve the “undruggable” challenge of many targets which are difficult in drug development. Moreover, its clinical transformation period and cost are relatively low, which makes oligonucleotide drug become the frontier of emerging biotechnology drug discovery. Brain diseases include a series of incurable diseases, such as neurodegenerative diseases, glioma, and motor neuron diseases. Many of them are age-related and regarded as aging-associated brain diseases. Due to the complex etiology, many targets are difficult to be drugged. At the same time, the existence of the barrier system “blood-brain barrier” in the brain makes most drugs unable to achieve effective accumulation at brain lesions, and many small molecule drugs have failed in clinical transformation. The specificity and sequence flexibility of oligonucleotide acid drugs provide new possibilities for drug development, but they also face the challenge of brain delivery. Although a variety of oligonucleotide drugs have been used in the medical market, brain-targeted oligonucleotide drugs are still extremely rare. This article reviewed recent advances and discussed key topics and clinical transformation challenges in this field, such as clinical approval cases, bottlenecks of brain-targeted delivery and current strategies, as well as potential targets for aging-related brain diseases.

Antitumor Drugs Targeting Mutant p53 Protein / 生物化学与生物物理进展

The p53 protein is an essential tumor suppressor in the human body that plays a critical role in preventing tumor formation by controlling cell cycle arrest and promoting apoptosis. Mutations in the p53 gene are frequently observed in more than 50% of tumor tissues and lead to the generation of mutant p53 proteins, which not only have a dominant-negative effect (DN) that hinders the function of wild-type p53 protein but also have gain-of-function (GOF) effects that stimulate tumor development by regulating cell metabolism, invasion, migration, and other processes. Therefore, mutant p53 protein has become a specific drug target for cancer therapy. However, the lack of a drug-binding pocket and smooth surface of mutant p53 proteins have made them undruggable targets for a long time. In recent years, with the development of high-throughput screening technology and an enhanced understanding of the structure and conformational changes exhibited by mutant p53 proteins, a multitude of small molecule compounds directed against mutant p53 protein have been identified, exhibiting substantial in vitro anti-tumor efficacy. Moreover, some of these compounds have entered clinical trials. This review summarized the direct and indirect strategies for the treatment of cancers targeting mutant p53, with a primary focus on the mechanisms of action of small molecule compounds that reactivate mutant p53 protein or degrade mutant p53 protein. The aim is to provide assistance for the development of innovative drugs targeting mutant p53 protein in the future.

Atypical antipsychotic drugs with strong alpha 1 receptor antagonism resulting in self-perceived hot in patients with schizophrenia： a case report / 四川精神卫生

This article reported a case of a patient with schizophrenia who experienced self-perceived fever and discomfort after taking atypical antipsychotic drugs with strong alpha 1 receptor antagonism， which included olanzapine， risperidone， paliperidone and clozapine. Such phenomenon was believed to be a medication side effect. Therefore， the patient switched to aripiprazole and the fever disappeared. This case report is intended to remind psychiatrists to pay attention to the side effects caused by atypical antipsychotic drugs with strong alpha 1 receptor antagonism as well as to suggest that various factors should be considered， including mechanisms of drug action， patient pathophysiology and individual differences， in order to improve treatment compliance and prognosis.
