AI Article Synopsis

  • New psychoactive substances (NPS) are not regulated by international drug treaties but can pose public health risks, with insufficient knowledge about their toxic effects.
  • Research conducted a literature review from 2017 to 2021, finding a significant lack of studies on the toxicity of many NPS, particularly concerning chronic and post-mortem effects, compared to acute toxicity.
  • The study highlights the urgent need for more comprehensive research on the health threats posed by NPS and their polydrug use effects.

Article Abstract

Purpose: New psychoactive substances (NPS) are not controlled under the Single Convention on Narcotic Drugs of 1961 or the 1971 Convention, but they may pose a public health threat. Knowledge of the main properties and toxicological effects of these substances is lacking. According to the current Drugs Law (Law n. 11.343/2006), the Brazilian Surveillance Agency issues directives for forbidden substances in Brazil, and structural classes of synthetic cannabinoids, cathinones, and phenylethylamines are considered illicit drugs. Considering that data on these controlled substances are scattered, the main objective of this work was to collect and organize data to generate relevant information on the toxicological properties of NPS.

Methods: We carried out a literature review collecting information on the acute, chronic, and post-mortem toxicity of these classes of NSP. We searched info in five scientific databases considering works from 2017 to 2021 and performed a statistical evaluation of the data.

Results: Results have shown a general lack of studies in this field given that many NPS have not had their toxicity evaluated. We observed a significant difference in the volume of data concerning acute and chronic/post-mortem toxicity. Moreover, studies on the adverse effects of polydrug use are scarce.

Conclusions: More in-depth information about the main threats involving NPS use are needed.

Objectives: Mal-deployment of the thoracic endovascular aortic repair (TEVAR) stent graft during a frozen elephant trunk (FET) procedure for an acute type A aortic dissection (ATAAD) leads to devastating complications. We report a hemiarch replacement with TEVAR stent graft covering the aortic arch vessels salvaged through an endovascular approach.

Methods: A 69-year-old man with ATAAD in 2018, status post-hemiarch repair with TEVAR, presented in 2023 with progressive dizziness/syncope and lower extremity hypertension with inability to tolerate anti-hypertensives.

Objectives: The aim of the study was to explore the alteration of microbiota and SCFA in gut and inflammation in acute exacerbation chronic obstructive pulmonary disease (AECOPD) patients, and to test the hypothesis that a disorder of gut microbiota will lead to the alteration of SCFA, which will aggravate inflammation in AECOPD patients.

Methods And Results: 24 patients with AECOPD and 18 healthy volunteers were included in the study. Gut microbiota were analyzed by 16S rDNA and serum was used to detect levels of inflammatory factors by ELISA.

Hematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for patients with hematologic malignancies and certain solid tumors and nonmalignant hematologic conditions. Both acute kidney injury (AKI) and chronic kidney disease (CKD) occur commonly after HSCT and are associated with significant morbidity and mortality. AKI and CKD in this setting may result from direct effects of the transplant or be caused by pretransplant bone marrow conditioning regimens and/or nephrotoxic agents administered in the post-transplant period.

Background: Aortoiliac disease poses a significant cardiovascular (CV) risk, especially in individuals with chronic kidney disease. This study aimed to assess the predictive role of chronic kidney disease in long-term major adverse CV events in patients submitted to aortoiliac revascularization due to severe aortoiliac atherosclerotic disease.

Methods: From 2013 to 2023, patients who underwent aortoiliac revascularization for TASC II type D lesions, including those with chronic kidney disease, were selected from a prospective cohort study.
