Published: March 2023

The tongue and floor of the mouth are high-risk sites for oral squamous cell carcinoma (OSCC), while smoking is its most significant risk factor. Recently, questions have been raised as to the role of the oral microbiome in OSCC because of a wealth of evidence demonstrating that the microbiome of OSCC differs from that of healthy mucosa. However, oral site and smoking also have a significant impact on oral microbial communities, and to date, the role these factors play in influencing the dysbiotic microbial communities of OSCC and precursor lesions has not been considered. This review aims to examine the influence of site and smoking on the oral microbiome and, in turn, whether these microbiome changes could be involved in oral carcinogenesis.

Primary bronchial leiomyosarcoma: a diagnostic challenge.

BMC Pulm Med

January 2025

Department of Pathology, Affiliated Hospital of Zunyi Medical University, Zunyi City, Guizhou Province, P.R. China.

Background: Pulmonary bronchial leiomyosarcoma is an extremely rare malignant tumour of the lung originating from the mesenchymal tissue. The retroperitoneal region is the most common site of leiomyosarcoma. It exhibits a high degree of malignancy and a poor prognosis, thereby highlighting the significance of early diagnosis of this disease.

This study aimed to explore PTPN2 expression levels in Hypopharyngeal Squamous Cell Carcinoma (HPSCC) tissues and their relationship with the clinical characteristics and prognosis of HPSCC patients. PTPN2, a protein tyrosine phosphatase, has recently emerged as a promising target for cancer immunotherapy, and in many previous studies, PTPN2 may have a significant role in the growth, differentiation, metabolism and immune response of head and neck malignant tumors. In this study, PTPN2 expression in Head and Neck Squamous Cell Carcinoma (HNSCC) and other cancer tissues was analyzed using datasets derived from the Sangerbox database.

Interventions for quitting vaping.

Cochrane Database Syst Rev

January 2025

Department of Health Promotion and Policy, University of Massachusetts, Amherst, MA, USA.

Rationale: There is limited guidance on the best ways to stop using nicotine-containing vapes (otherwise known as e-cigarettes) and ensure long-term abstinence, whilst minimising the risk of tobacco smoking and other unintended consequences. Treatments could include pharmacological interventions, behavioural interventions, or both.

Objectives: To conduct a living systematic review assessing the benefits and harms of interventions to help people stop vaping compared to each other or to placebo or no intervention.

Contingency management (CM), an evidence-based behavioral strategy that rewards positive behavior change including tobacco cessation, is rarely offered to support people with HIV (PWH) who smoke. In this study, we explored perspectives among patients and research staff engaged in a multi-site randomized clinical trial involving clinical pharmacist-delivered CM within HIV clinics. Between February and September 2023, we conducted 1:1 interviews with 12 PWH randomized to receive CM and one focus group with 8 staff (i.

Objectives: The objective of this study was to assess the completeness of registration of secondary preventive variables comparing on-site visits with telephone consultations during follow-up after myocardial infarction.

Design: This was an observational study based on the Swedish quality registry SWEDEHEART.

Setting And Outcome Measures: We analysed the proportion of missing values for major secondary preventive target data registered at the 2-month and 1-year follow-up visits, during 2006-2022 (n=101 199).
