Summary: Individual matching in case-control studies improves statistical efficiency, but strict matching criteria can lead to selection bias. This study introduces flex matching, an algorithm that selects controls for cases using multiple rounds of control selection with successively relaxed matching criteria. The results show that flex matching produces the least biased estimates with the smallest standard errors, making it a valuable approach in case-control designs.

Summary: Mints are valued for their specific essential oil used in food, pharmaceutical and cosmetic industry. Chemical compounds differing between species cause changes in medicinal/pharmacological properties, antioxidant activities or smell sensations. UV-VIS spectrophotometry and FTIR-ATR spectroscopy were used to record spectral fingerprints of mint varieties, and a chemometric approach involving SIMCA was used for quality control. Discrimination of peppermint and spearmint samples was done using PLS-DA or SVM, with model performance ranging from 60 to 80% depending on spectroscopic data and harvest season.

Summary: Matching by a confounder in a case-control study often leads to control-selection bias and net bias, which can be affected by the direction and magnitude of the confounding. Previous assumptions that matching for a single confounder is sufficient to remove all confounding and that associations are monotonic have been challenged. It is now understood that the implications of matching by confounders in case-control studies are more complex and require further methodological research.

Summary: One central goal of observational study design is to incorporate non-experimental data into an approximate randomized controlled trial using statistical matching. However, residual imbalance due to imperfect matching of observed covariates often persists. This article presents two generic classes of exact statistical tests for a biased randomization assumption and introduces a quantity called residual sensitivity value (RSV) as a means to quantify the level of residual confounding due to imperfect matching of observed covariates in a matched sample. The proposed methodology is demonstrated through a re-examination of a famous observational study.

Summary: Single-cell sequencing has revolutionized the identification of differentially expressed genes (DEGs) by providing high resolution for heterogeneous cell tissues. However, current analysis mainly focuses on comparing different cell types within the same individual. This study proposes a nonparametric method called barycenter single-cell differential expression (BSDE) to identify DEGs in case-control studies. The method overcomes the limitations of parametric approaches and accurately detects differential expressions. It is demonstrated through simulations and real data analysis that BSDE can effectively identify cell type-specific DEGs. The availability of the R package and datasets further facilitate its application in research.

Summary: In observational studies, the matched case-control approach is commonly used to compare treatment effects by matching cases with controls. This approach can be more powerful for testing treatment effects when outcomes are rare. Additionally, it can provide better match quality in studies investigating the effects of certain treatments on specific conditions.

Summary: The authors propose a transfer-learning-based deep learning model, transfer-learning-ResUnet, to retrieve the nighttime thermodynamic phase (CP) of clouds from thermal infrared channels. Cloud products of Himawari-8 and Moderate-resolution Imaging Spectroradiometers were used as labels during training. The accuracy of the CP retrieval was confirmed by a benchmark obtained by the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations. During three independent months, the daytime and nighttime retrieval accuracy of the CP was 0.867 and 0.816, respectively, which was superior to that of the Himawari-8 operational product in the daytime (0.788).

Summary: Limited evidence exists regarding the exposure-effect relationship between lung-cancer risk and hexavalent chromium (Cr(VI)) or nickel. This study found that occupational exposure to Cr(VI) and nickel was associated with lung-cancer risks, particularly in men. In men, the highest quartile of cumulative exposure to CR(VI) and nickel were both significantly associated with increased odds ratios for lung cancer.

Summary: The study aimed to assess the impact of risk-reducing surgery on quality of life for breast cancer and ovarian cancer prevention. The results showed that risk-reducing mastectomy and risk-reducing salpingo-oophorectomy can reduce cancer-related distress and do not affect health-related quality of life. However, body image problems should be considered after risk-reducing mastectomy, and sexual dysfunction and menopause symptoms after risk-reducing salpingo-oophorectomy. Risk-reducing early salpingectomy and delayed oophorectomy may be a promising alternative to mitigate quality of life-related risks.

Summary: This study compared the accuracy and agreement of three breast cancer risk prediction models and found substantial variability in individual risk categorization. Depending on the model and risk threshold used, there were significant differences in breast cancer risk estimates for individuals. This variability can have adverse effects on screening, prevention, and quality of life, and clinicians need to be aware of the differences between models and the false-positive and false-negative rates when discussing with patients.

Summary: Polygenic risk scores (PRSs) are an important part of accurate breast cancer risk prediction, but they need to be calibrated for different ethnicities. This study found that commercially available PRSs, which assume that Ashkenazi Jewish (AJ) population is of White European (WE) origin, do not accurately predict breast cancer risk in AJ women due to differences in effect allele frequencies. It is necessary to recalibrate PRSs using AJ-specific effect allele frequencies.
