AI Article Synopsis
- Assessing changes in substance-related disorder (SRD) rates and health outcomes helps inform public health policies aimed at reducing drug and alcohol harms in Canada.
- The study analyzed health data from five provinces (Alberta, Manitoba, Ontario, Québec, Nova Scotia) between 2001 and 2018, focusing on diagnostic and mortality rates associated with SRD among Canadians aged 12 and older.
- Results showed an increase in annual SRD diagnostic rates in Alberta, Ontario, and Nova Scotia, while Manitoba and Québec remained stable; higher mortality rates were linked to SRD individuals compared to the general population.
Article Abstract
Context: Assessing temporal changes in the recorded diagnostic rates, incidence proportions, and health outcomes of substance-related disorders (SRD) can inform public health policymakers in reducing harms associated with alcohol and other drugs.
Objective: To report the annual and cumulative recorded diagnostic rates and incidence proportions of SRD, as well as mortality rate ratios (MRRs) by cause of death among this group in Canada, according to their province of residence.
Methods: Analyses were performed on linked administrative health databases (AHD; physician claims, hospitalizations, and vital statistics) in five Canadian provinces (Alberta, Manitoba, Ontario, Québec, and Nova Scotia). Canadians 12 years and older and registered for their provincial healthcare coverage were included. The International Classification of Diseases (ICD-9 or ICD-10 codes) was used for case identification of SRD from April 2001 to March 2018.
Results: During the study period, the annual recorded SRD diagnostic rates increased in Alberta (2001-2002: 8.0‰; 2017-2018: 12.8‰), Ontario (2001-2002: 11.5‰; 2017-2018: 14.4‰), and Nova Scotia (2001-2002: 6.4‰; 2017-2018: 12.7‰), but remained stable in Manitoba (2001-2002: 5.5‰; 2017-2018: 5.4‰) and Québec (2001-2002 and 2017-2018: 7.5‰). Cumulative recorded SRD diagnostic rates increased steadily for all provinces. Recorded incidence proportions increased significantly in Alberta (2001-2002: 4.5‰; 2017-2018: 5.0‰) and Nova Scotia (2001-2002: 3.3‰; 2017-2018: 3.8‰), but significantly decreased in Ontario (2001-2002: 6.2‰; 2017-2018: 4.7‰), Québec (2001-2002: 4.1‰; 2017-2018: 3.2‰) and Manitoba (2001-2002: 2.7‰; 2017-2018: 2.0‰). For almost all causes of death, a higher MRR was found among individuals with recorded SRD than in the general population. The causes of death in 2015-2016 with the highest MRR for SRD individuals were SRD, suicide, and non-suicide trauma in Alberta, Ontario, Manitoba, and Québec.
Discussion: Linked AHD covering almost the entire population can be useful to monitor the medical service trends of SRD and, therefore, guide health services planning in Canadian provinces.

Cystic Echinococcosis (CE) is a zoonotic disease caused by sensu lato. Diagnosing CE primarily relies on imaging techniques, and there is a crucial need for an objective laboratory test to enhance the diagnostic process. Today, cell-free DNAs (cfDNAs) have gained importance regarding their biomarker potential.

Objective: To retrospectively analyze the incidence of infections in elderly acute myeloid leukemia (AML) patients undergoing induction therapy with venetoclax combined with hypomethylating agents and to compare these findings with those from patients receiving standard or low-dose chemotherapy.
Methods: Medical records of 169 elderly (≥60 years old) AML patients diagnosed via MICM (morphology, immunology, cytogenetics, and molecular genetics) at the First Affiliated Hospital of USTC between June 2019 and June 2022 were reviewed. Patients were divided into three groups: venetoclax combined with hypomethylating agents group (targeted therapy group), standard chemotherapy group, and low-dose chemotherapy group.

Background: tNGS and mNGS are valuable tools for diagnosing pathogens in lower respiratory tract infections (LRTIs), which subsequently influence treatment strategies. However, the impact of tNGS and mNGS on antimicrobial stewardship in patients with LRTIs remains unclear.
Methods: Patients diagnosed with LRTIs who underwent tNGS or mNGS between June 2021 and January 2024 were included.
The subfamily Mileewinae in China comprises one tribe (Mileewini), four genera (, , , ), and 71 species, yet only 11 mitochondrial genomes have been published. This study aimed to elucidate ambiguous diagnostic traits in traditional taxonomy and examined phylogenetic relationships among genera by sequencing mitochondrial genomes from 16 species. The lengths of the mitochondrial genomes ranged from 14,532 to 15,280 bp, exhibiting an AT content of 77.

Sclerosing epithelioid fibrosarcoma (SEF) is a rare and aggressive neoplasm composed of epithelioid cells arranged in strands and nests embedded in a highly sclerotic collagenous stroma. We report a case of a 36-year-old man who started with lumbar pain, with extension to both legs, night sweats, and weight loss. He underwent magnetic resonance imaging (MRI) of the lumbar spine; computed tomography (CT) scan of the chest, abdomen, and pelvis; and [18F]-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scan.
