Prospective Mental Images: A Transdiagnostic Approach to Negative Affectivity and Mood Dysregulation among Borderline Personality Disorder and Depression.
2024
Behavioral sciences (Basel, Switzerland)
Kroener J, Schaitz C, Sosic-Vasic Z
Plain English This study looked at how negative feelings (negative affectivity) affect the intrusive thoughts people with Borderline Personality Disorder (BPD) and depression have about self-harm. Researchers found that people with BPD and depression experienced more of these troubling images than healthy individuals. Negative feelings were found to connect these images to the mental health issues, meaning that when someone feels worse, they're more likely to have these intrusive thoughts.

The German Impact of Future Events Scale (IFES-S): Adaption and Validation for Clinical Samples.
2019
Frontiers in psychiatry
Kroener J, Schaitz C, Maier A, Connemann B, Sosic-Vasic Z
Plain English This study created and tested a German version of a tool called the Impact of Future Events Scale (IFES-S), which is used to measure how often people have troubling thoughts about future events, especially in those with psychological disorders. The researchers found that this new tool is reliable and effective, with a high consistency score of 0.93 and an optimal cutoff score of 23 to distinguish between those with mental health issues and healthy individuals. This matters because accurately measuring future intrusive thoughts can help in understanding and treating conditions like depression and anxiety more effectively.
Who this helps: Patients with psychological disorders and their doctors.

2011
Clinical breast cancer
Brufsky A, Hoelzer K, Beck T, Whorf R, Keaton M +14 more
Plain English This study looked at how well two different treatments for metastatic breast cancer worked. One treatment combined paclitaxel and bevacizumab (PB), while the other added gemcitabine to that mix (PB+G). Researchers found that 48.9% of patients responded to PB, and 58.7% responded to PB+G, but the difference wasn’t statistically significant. Patients treated with PB had a median progression-free survival of 8.8 months compared to 11.3 months for those on PB+G, although this also wasn’t a significant difference. Importantly, patients on the combined treatment experienced more severe side effects like low white blood cell counts and difficulty breathing, plus they reported worse quality of life.
Who this helps: This research helps breast cancer patients and their doctors by highlighting the risks and benefits of different treatment options.
The use of canines in the detection of human cancers.
2008
Journal of alternative and complementary medicine (New York, N.Y.)
Gordon RT, Schatz CB, Myers LJ, Kosty M, Gonczy C +12 more
Plain English This study explored whether trained dogs can identify cancer in humans by detecting specific scents in urine samples. Out of 6 dogs tested for breast cancer, only 2 showed some ability to distinguish cancerous urine, while none identified prostate cancer effectively among 4 dogs tested. The findings didn't fully support the idea of using dogs for cancer detection, but they hint at the potential for this method with improved training and sample management.
Who this helps: This helps researchers and healthcare professionals exploring alternative cancer detection methods.
Case study of the morphologic variation of circulating tumor cells.
2007
Human pathology
Marrinucci D, Bethel K, Bruce RH, Curry DN, Hsieh B +8 more
Plain English This study looked at a 38-year-old woman with advanced breast cancer to understand the characteristics of circulating tumor cells (CTCs) in her blood. The researchers found 659 CTCs in a small blood sample, which varied greatly in shape and size and showed signs of cell death. This is important because it shows that CTCs in the bloodstream can provide a complete picture of the cancer, reflecting the diverse cells found in both the primary tumor and its metastases.
Who this helps: This information can benefit doctors and researchers working on better ways to detect and treat breast cancer.
Hsieh HB, Marrinucci D, Bethel K, Curry DN, Humphrey M +8 more
Plain English This study focused on a new device that quickly detects rare cancer cells in the blood of patients, using a technology called fiber-optic array scanning. Researchers found that this device, the FAST cytometer, can identify these cells 500 times faster than traditional methods, allowing for immediate results without needing to concentrate the blood samples first. This advancement is significant because it enables doctors to monitor cancer more effectively and potentially predict how the disease will progress.
Who this helps: This helps patients and doctors by providing faster and more accurate cancer monitoring tools.

Journal of clinical oncology : official journal of the American Society of Clinical Oncology
Meisenberg BR, Miller WE, McMillan R, Callaghan M, Sloan C +6 more
Plain English This study looked at giving high-dose chemotherapy with stem-cell rescue to patients outside of the hospital. Out of 113 patients treated, 85% participated in outpatient programs, and 70% of them were never readmitted to the hospital after treatment. The research showed that patients who received chemotherapy as outpatients spent significantly less time in the hospital, with an average stay of just 2.8 days compared to 18.3 days for those treated as inpatients.
Who this helps: This benefits cancer patients who can avoid long hospital stays while receiving their treatment.
Alternating combination chemotherapy for stages III and IV ovarian carcinoma.

Young JA, Johnson A, Kroener J, Koziol JA, Saltzstein S +4 more
Plain English This study focused on treating 39 patients with late-stage ovarian cancer using a specific chemotherapy combination after surgery. Of the 19 patients who could be measured, 53% showed at least some improvement, and 18% became free of cancer after additional surgery, though some later relapsed. Overall, patients lived an average of 21 months, but the combined treatment didn't show better results than using either chemotherapy alone.
Who this helps: This research benefits ovarian cancer patients and their doctors by providing insights into treatment options.
