Background: The Wetmore Tuberculosis (TB) Clinic in New Orleans serves patients who often lack primary care (PC) or specialty care (SC), which is complicated by comorbidities. An initiative to provide on-site PC and coordinate care aims to enhance TB patient management.

Methods: Data collection involved categorizing patients based on their PC status: Group I (regular PC), Group II (intermittent PC), and Group III (no PC), with on-site Nurse Practitioner-based Bridge Care (NPBC) provided as needed.

Methane emissions from the global oil and gas value chain are a major contributor to climate change, and their mitigation could avoid 0.1 °C of warming by 2050. Here, we synthesize nearly a decade of research encompassing thousands of multiscale methane measurements along the oil and gas value chain (production to end use) to better constrain estimates of methane emissions from Canada's energy sector and to identify research gaps contributing to uncertainty in current estimates.

Article Synopsis
  • Leakage from oil and gas wells contributes to methane emissions and can contaminate groundwater, making well integrity crucial for environmental protection.
  • Incomplete industry reporting in Canada leads to discrepancies in government emissions inventories, affecting estimates of wellbore methane emissions in British Columbia and Alberta, which range from 23 to 176 kilotons.
  • The study highlights the underreporting of leaks, recommends better data tracking and testing methods, and suggests using optical gas imaging cameras to enhance monitoring efforts.

The USPSTF has updated Latent TB Infection (LTBI) screening and treatment recommendations in 2023; describing treatment courses, side effects and benefits associated with each regimen. Overall, rifampin-containing shortened regimens are the preferred modality for LTBI treatment. A recent study in 2023 evaluated adherence and tolerance of the isoniazid(INH) + rifapentine(RPT), or "3HP" regimen and identified patient groups that may be at higher risk for non-completion of this regimen.

Idiopathic pulmonary fibrosis (IPF) carries significant mortality and unpredictable progression, with limited therapeutic options. Designing trials with patient-meaningful endpoints, enhancing the reliability and interpretability of results, and streamlining the regulatory approval process are of critical importance to advancing clinical care in IPF. A landmark in-person symposium in June 2023 assembled 43 participants from the US and internationally, including patients with IPF, investigators, and regulatory representatives, to discuss the immediate future of IPF clinical trial endpoints.
