Summary: An adequate bowel preparation for CT colonography can be achieved without diet restriction, using a reduced amount of cathartic agent and fecal tagging. Patients' characteristics, such as age, gender, and presence of diverticula, can influence bowel preparation and affect patients' compliance.

Summary: This study retrospectively analyzed the reports of 1044 patients (Institution A) and 1094 patients (Institution B) who underwent CT colonography, and found that the incidence of colonic lipoma was 2.2% in women and 2.3% in men. Most colonic lipomas were located in the ascending colon, and the majority were sessile with smaller diameters.

Summary: The study revealed that over 30% of CT colonography cases showed bacterial airborne dissemination, compared to less than 10% in control examinations. Additionally, it was confirmed that the room disinfection policy in the CT department effectively eliminates pathogenic bacteria from surfaces in the patient environment.

Summary: The study compared the quality and acceptability of three different low-volume bowel preparation regimens for patients undergoing CTC. The findings showed that the best examination quality was achieved when a single dose of PEG was administered the day before CTC. Dolichocolon and secondary constipation were identified as risk factors for inadequately tagged colonic segments.

Summary: This study investigates the use of an 'electronic biopsy' (EB) technique in computed tomographic colonography (CTC) for further differentiation and 2D image correlation of endoluminal lesions in the air spaces. The study found that EB significantly improves the 3D gray-level presentation for evaluating the surface and inside of endoluminal lesions and achieves better 3D to 2D image correlation compared to other techniques. EB can be used in CTC to improve the differentiation of endoluminal lesions and increase the correlation between 3D and 2D images of the lesions.

Summary: This article discusses the recommendations for annual screening of lung cancer with chest low-dose CT and screening of colorectal cancer with CT colonography. It also explores the possibility of combining these two screenings in a single CT appointment. The article highlights the importance of Computer Assisted Diagnosis systems and identifies some uncertainties that need to be addressed.

Summary: This study aimed to evaluate the usefulness of CT colonography (CTC) and/or PET-CT in detecting synchronous proximal colon carcinomas in patients with incomplete colonoscopy due to distal colorectal cancer. The results showed that CTC, PET-CT, or their combination could detect synchronous carcinomas and potentially alter the surgical plan.

Summary: Intestinal malrotation is more commonly detected in adulthood through CT colonography. The prevalence is higher in adults identified through CTC screening compared to incomplete optical colonoscopy referrals, with many cases initially diagnosed during CTC screening and frequently missed in other abdominal imaging examinations.

Summary: The study found no evidence of patients or staff acquiring COVID-19 infection following CTC appointments, and no significant asymptomatic COVID-19 cases were detected based on lung base changes. The results suggest that current practice is unlikely to contribute significantly to the spread of SARS-nCOV2, highlighting the importance of maintaining service provision for cancer and polyp detection.

Summary: This study used 2019 nationally representative cross-sectional survey data to assess the nationwide utilization of CT colonography (CTC) and predictors of CTC utilization. The results showed that the utilization of CTC remains low nationwide and that Black and Hispanic participants were more likely to undergo CTC. Promoting CTC may help reduce racial and ethnic disparities in colorectal cancer screening.

Summary: Forest loss and degradation pose the greatest threats to global biodiversity, and finding a balance between conservation and wood production remains a challenge. Expanding high-yielding tree plantations could provide more forest land for protection, but leads to reduced biodiversity, while adopting extensive ecological management may better simulate natural forest structures with compromised wood yields.

Summary: A study on the impact of tree plantations on native bird biodiversity found that bird abundance changes dynamically during early plantation development, with many species peaking in abundance either very early in development or at canopy closure, then declining by the end of a 30-year period. Broadleaf cover only increased habitat longevity for one bird species (Wilson's warbler), contrary to the hypothesis.

Summary: By experimentally broadcasting murrelet calls at potential breeding sites, it was found that simulating conspecific presence can attract potential prospectors and lead them to occupy the site in the following year. This suggests that social information influences site selection for murrelet breeding.

Summary: Postharvest Douglas-fir forests supported a range of wild bee species during the early seral period, with observed bee species richness and abundance strongly associated with floral resources. However, stands within three years of harvest harbored the most bees and greatest bee diversity, indicating their values to bees are limited to a short window of time during the early seral period. Actions that promote floral resources and maintain early seral conditions on the landscape are expected to have the greatest benefit to wild bees and other insect pollinators within managed forests.

Summary: Microclimatic refugia are crucial for biodiversity conservation under climate change, with stable microclimate temperature offsets observed over time. However, broad-scale climatic variation can still significantly impact microclimate temperatures, emphasizing the importance of maintaining old-growth and complex forest habitats to protect these microclimatic refugia.

Summary: Understanding how herbicides affect biodiversity, yield, and economic benefits is crucial for managing natural resources. This study found that herbicides reduced species richness and had varying effects on different trophic groups in forest ecosystems. Financial discounting also played a significant role in modifying biodiversity-revenue relationships caused by management intensity.

Summary: The research shows that increasing management intensity through herbicide use in forests may decrease biodiversity conservation and certain non-timber services, pointing to trade-offs between some services and timber production. However, some services appear to be compatible with timber production, suggesting that a balance may need to be struck for optimal ecosystem service provision across managed forest landscapes.

Summary: Ecologists are seeing a renaissance in natural history, now characterized by technological advancements and statistical tools that enable systematic collection and analysis of detailed observations, providing a foundation for hypothetico-deductive research and conservation efforts. Next-generation natural history datasets have transformed anecdotal observations into robust scientific evidence, encouraging scientists to embrace detailed descriptions of nature and engaging both scientists and non-scientists in the wonders of the natural world.
