BACKGROUND Lung cancer is the largest contributor to mortality from cancer. The National Lung Screening Trial (NLST) showed that screening with low-dose helical computed tomography (CT) rather than with chest radiography reduced mortality from lung cancer. We describe the screening, diagnosis, and limited treatment results from the initial round of screening in the NLST to inform and improve lung-cancer– screening programs. METHODS At 33 U.S. centers, from August 2002 through April 2004, we enrolled asymptomatic participants, 55 to 74 years of age, with a history of at least 30 pack-years of smoking. The participants were randomly assigned to undergo annual screening, with the use of either low-dose CT or chest radiography, for 3 years. Nodules or other suspicious findings were classified as positive results. This article reports findings from the initial screening examination. RESULTS A total of 53,439 eligible participants were randomly assigned to a study group (26,715 to low-dose CT and 26,724 to chest radiography); 26,309 participants (98.5%) and 26,035 (97.4%), respectively, underwent screening. A total of 7191 participants (27.3%) in the low-dose CT group and 2387 (9.2%) in the radiography group had a positive screening result; in the respective groups, 6369 participants (90.4%) and 2176 (92.7%) had at least one follow-up diagnostic procedure, including imaging in 5717 (81.1%) and 2010 (85.6%) and surgery in 297 (4.2%) and 121 (5.2%). Lung cancer was diagnosed in 292 participants (1.1%) in the low-dose CT group versus 190 (0.7%) in the radiography group (stage 1 in 158 vs. 70 participants and stage IIB to IV in 120 vs. 112). Sensitivity and specificity were 93.8% and 73.4% for low-dose CT and 73.5% and 91.3% for chest radiography, respectively. CONCLUSION The NLST initial screening results are consistent with the existing literature on screening by means of low-dose CT and chest radiography, suggesting that a reduction in mortality from lung cancer is achievable at U.S. screening centers that have staff experienced in chest CT.

Self-managed abortion, when a person performs their own abortion without clinical supervision, is a model of abortion care used across a range of settings. To provide a comprehensive synthesis of the available literature on self-managed abortion, we conducted a systematic search for peer-reviewed research in April 2019 in PubMed, Embase, Web of Science, Popline, PsycINFO, Google Scholar, Scielo, and Redalyc. We included studies that had a research question focused on self-managed abortion; and were published in English or Spanish. The combined search returned 7,167 studies; after screening, 99 studies were included in the analysis. Included studies reported on methods, procurement, characteristics of those who self-managed, effectiveness, safety, reasons for self-managed abortion, and emotional and physical experiences. Numerous abortion methods were reported, most frequently abortion with pills and herbs. Studies reporting on self-managed medication abortion reported high-levels of effectiveness. We identify gaps in the research, and make recommendations to address those gaps.

Objectives In 2013, Texas passed omnibus legislation restricting abortion services. Provisions restricting medical abortion, banning most procedures after 20 weeks and requiring physicians to have hospital admitting privileges were enforced in November 2013; by September 2014, abortion facilities must meet the requirements of ambulatory surgical centers (ASCs). We aimed to rapidly assess the change in abortion services after the first three provisions went into effect. Study Design We requested information from all licensed Texas abortion facilities on abortions performed between November 2012 and April 2014, including the abortion method and gestational age (<12 weeks versus ≥12 weeks). Results In May 2013, there were 41 facilities providing abortion in Texas; this decreased to 22 in November 2013. Both clinics closed in the Rio Grande Valley, and all but one closed in West Texas. Comparing November 2012–April 2013 to November 2013–April 2014, there was a 13% decrease in the abortion rate (from 12.9 to 11.2 abortions/1000 women age 15–44). Medical abortion decreased by 70%, from 28.1% of all abortions in the earlier period to 9.7% after November 2013 (p<0.001). Second-trimester abortion increased from 13.5% to 13.9% of all abortions (p<0.001). Only 22% of abortions were performed in the state’s six ASCs. Conclusions The closure of clinics and restrictions on medical abortion in Texas appear to be associated with a decline in the in-state abortion rate and a marked decrease in the number of medical abortions. Implications Supply-side restrictions on abortion—especially restrictions on medical abortion—can have a profound impact on access to services. Access to abortion care will become even further restricted in Texas when the ASC requirement goes into effect in 2014.

Clinic closures after House Bill 2 resulted in significant burdens for women able to obtain care.
