Chilli pepper is one of the most important and widely cultivated pepper types in China. It has high nutritional and economic value. Capsicum frutescens L. is one of the chilli pepper types in production. In October 2022, a new disease showing blight of the entire chilli pepper plant was observed in Nanchang City, Jiangxi Province. The fungal isolates consistently obtained from the diseased samples were identified as Diaporthe caryae C. M. Tian & Qin Yang based on morphological characteristics, pathogenicity test and phylogenetic analysis of four genes, including internal transcribed spacer region (rDNA‐ITS), translation elongation factor 1‐alpha gene (TEF1), beta‐tubulin gene (TUB2), and calmodulin (CAL). Although other Diaporthe species have been reported as pathogens of peppers previously, to our knowledge, this is the first report of D. caryae causing stem blight of pepper in the world. D. caryae was reported to be able to infect various fruit trees such as kiwifruit, peach, pear, and pecan, resulting in kiwifruit rot, peach constriction canker, pear shoot canker, and pecan dieback, respectively. The host range of D. caryae has expanded from fruit trees to vegetable crops. [ABSTRACT FROM AUTHOR]

Background: To investigate a 3-stage screening procedure and explore the clinical features of subjects at Clinical High Risk (CHR) for psychosis in a representative sample of Chinese college students. Methods: An epidemiological survey of the prevalence of the CHR syndrome in Chinese college students that was selected by stratified random sampling from Shanghai, Nanjing and Nanchang cities was done following a 3-stage procedure. Participants were initially screened with the Prodromal Questionnaire-brief version (PQ-B), and whose distress score of PQ-B exceeded 24 would be invited to a telephone assessment using the subscale for positive symptoms of the Scale of Prodromal Symptoms (SOPS)/Structured Interview for Prodromal Syndromes (SIPS). Lastly, participants who scored 3 or higher in any item of the subscale would be administered with the SIPS interview conducted by trained researchers to confirm the diagnosis of CHR syndrome. Results: Twenty-three thousand sixty-three college students completed the survey during September 2017 to October 2018. Seventy-two students were diagnosed as CHR subjects, and the detection rate in the total sample was 0.3%. The peak age range for the first diagnosis of CHR was 17 to 20 years. Thirteen and forty-six were set as the cutoff points of PQ-B total score and distress score to balance the greatest sensitivity and specificity. Binary logistic regression revealed that 8 items in PQ-B showed significant distinction for detecting CHR subjects. Conclusions: The 3-stage screening method can be utilized in the detection of CHR subjects for psychosis in the general population, during which delusional ideas, perceptual abnormalities and suspiciousness deserve great attention.
