This study conducted confidence interval estimation to assess variation in the fat content of hamburger samples from a restaurant, using Minitab. The standard for mean fat content was set at 15 grams as per accepted regulatory requirements, with a standard deviation of 1 gram. In this study twenty samples were selected at random and statistical process control was determined by the individual moving range (I-MR) test. The I-MR chart conducted on twenty individual hamburger samples showed that the fat content was in statistical process control.

Previous studies confirmed that ground-glass nodules (GGNs) with certain CT manifestations had a higher probability of malignancy. However, differentiating patchy ground-glass opacities (GGOs) and GGNs has not been discussed solely. This study aimed to investigate the differences between the CT features of benign and malignant patchy GGOs to improve the differential diagnosis.

In low-resource settings with weak health systems, the WHO recommends clinical breast examination (CBE) as the most cost-effective breast screening modality for women. Evidence shows that biennial CBE leads to significant downstaging of breast cancer in all women. This study investigated the prevalence and factors associated with the uptake of CBE among women of reproductive age in Lesotho.

We aim to clarify the controversial associations between EBV-related antibodies and gastric cancer risk. Our research reveals positive associations between EBNA1-IgA and VCA-IgA and gastric cancer risk in southern China. We thus postulate that EBNA1-IgA and VCA-IgA might appear to be potential biomarkers for gastric cancer.
