ObjectiveEarly blight is a common destructive disease in the growth process of Solanaceae crops, which can lead to crop failure and serious losses. Traditional crop disease detection methods are difficult to detect disease characteristics in a timely manner during the incubation period of disease, and thus take scientific and effective prevention and control measures. This study obtained hyperspectral images of early blight of peppers at different infection stages through continuous monitoring with a hyperspectral imager. The earliest identifiable time during the incubation period of early blight in peppers (the earliest identifiable time during the incubation period in this experiment was 24 h after inoculation) was determined using the spectral angle cosine-correlation coefficient and Chebyshev distance. MethodsTaking the symptoms of the latent period of early blight in peppers as the research object, 13 characteristic wavelengths were selected using a genetic algorithm. An identification model of crop disease latent period symptoms based on spectral features was established through optimized combinations of characteristic wavelengths combined with a logistic regression model. Simultaneously, a recognition model of the latent period of early blight in peppers based on image texture features was established using local binary patterns. ResultsThe experiment was tested with 120 samples. The accuracy of the identification model of crop disease latent period symptoms based on spectral features reached over 93% in both the training set and the test set. The accuracy of the identification model of crop disease latent period symptoms based on texture features reached 98.96% and 100% in the training set and test set, respectively. ConclusionBoth spectral features and texture features can be used to detect and identify crop disease latent period symptoms. Texture features more significantly revealed the characteristics of the latent period of the disease compared to spectral features, effectively improving the detection performance of the model. The research results in this article can provide theoretical references for monitoring and identifying other crop disease latent period symptoms.

This report summarized and analyzed the clinical data of 3 patients with food-borne botulism admitted to our department. One case was sporadic, while the other two involved family members living together. All patients initially presented with blurred vision, ptosis, and dysphagia, and the disease progressed rapidly. During the course of the disease, all three cases developed respiratory failure; one patient received non-invasive ventilatory support, whereas the other two required invasive ventilator assisted ventilation. The serum toxin tests of the 3 patients were all positive for botulinum toxin type A. Sporadic food-borne botulism shares similar early symptoms and signs to myasthenia gravis and Guillain-Barre syndrome, and requires careful differential diagnosis. Botulinum antitoxin serum is the only effective treatment, and empirical antitoxin administration can be initiated immediately upon suspicion of botulism. Early detection and timely specific treatment are critical for improving patient outcomes.

Objective:To evaluate the clinical efficacy of a novel surgical approach of debridement, antibiotics, and implant retention (DAIR) with flap transfer, for treating chronic implant infections in bone tumor patients.Methods:A retrospective review was conducted on nine consecutive patients [6 males, 3 females; median age 35(27, 51) years, range 9-71] who underwent a modified procedure of DAIR plus flap transfer between November 2022 and January 2024. The cohort included six cases of chronic periprosthetic joint infection and three cases of chronic plate and screw infection. Tumor diagnoses included seven primary malignant tumors (osteosarcoma=5, undifferentiated pleomorphic sarcoma of bone=1, synovial sarcoma=1) and two bone metastasis of renal cell carcinoma. The procedure involved wide, radical debridement, meticulous removal of biofilm from implants and surrounding soft tissue, followed by the transfer of a well vascularized musculocutaneous flap to fully envelope the contaminated interface. Pre-operative clinicopathological data, surgical details, postoperative complications and infection recurrence were analyzed.Results:The median interval between initial implantation and debridement was 10.0(3.3, 14.8) months. Median follow-up after debridement was 15.9(15.4, 18.2) months. All nine surgeries were completed as planned: six musculocutaneous flaps, two fasciocutaneous flaps and one muscle-only flap. Implants were preserved in six patients; two required subsequent removal for recurrent infection, and one patient later underwent amputation for tumor recurrence. Infection-free implant survival at 3, 6 and 12 months was 88.9%, 87.5% and 87.5%, respectively. Major complications included one donor-site hematoma, one donor-site sensory deficit and one wound healing delay. All the complications were well management. Both reinfections occurred in proximal tibial prostheses, likely due to limited flap coverage options and local anatomical constraints.Conclusion:Although reinfections happened in two cases DAIR with flap transfer provides promising short-term infection control in patients with chronic implant-associated infections following bone tumor surgery.

Objective:To evaluate spinal-pelvic mobility and sagittal spinal-pelvic alignment characteristics in patients with developmental dysplasia of the hip (DDH), and to investigate differences in sagittal spinal-pelvic parameters between patients with DDH and those with osteonecrosis of the femoral head (ONFH).Methods:A total of 55 patients with DDH who underwent primary total hip arthroplasty (THA) at the Affiliated Hospital of Xuzhou Medical University between April 2021 and March 2024 were retrospectively analyzed. The cohort included 8 males and 47 females, with a mean age of 56.16±10.82 years (range: 26-76 years). Among them, 18 patients had bilateral DDH and 37 had unilateral DDH. Fifty-five age- and sex-matched patients with ONFH were selected as the control group. Unilateral DDH cases were classified according to the Hartofilakidis classification: 18 cases of type A, 13 cases of type B, and 6 cases of type C. Lateral spinal-pelvic radiographs were used to measure pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), and lumbar lordosis (LL) in both standing and sitting positions. Changes in sagittal spinal-pelvic parameters between standing and sitting positions were analyzed to assess spinal-pelvic mobility. Spinal-pelvic mobility was considered abnormal if △SS was outside the range of 10°-30°. Abnormal mobility was further categorized as stiffness (△SS<10°) or hypermobility (△SS>30°).Results:The PI (52.37°±12.43°), standing PT (12.13°±9.50°), and sitting PT (36.49°±13.43°) of DDH patients were significantly higher than those of ONFH patients (44.88°±11.38°, 7.80°±11.36°, and 28.91°±11.38°, respectively), with statistically significant differences ( P<0.05). Abnormal spinal-pelvic mobility, including both stiffness and hypermobility, was observed in 53% of DDH patients, with stiffness accounting for 20%. These proportions were significantly higher than those in ONFH patients, which were 24% and 6%, respectively ( P<0.05). The prevalence of abnormal spinal-pelvic mobility in Hartofilakidis type C DDH patients was 83%, significantly higher than the 30.8% observed in type B patients (χ 2=4.550, P=0.033). The standing LL (54.37°±11.59°) and sitting LL (28.56°±15.51°) in unilateral DDH patients were significantly greater than those in bilateral DDH patients (46.88°±15.30° and 20.42°±9.77°, respectively), with statistically significant differences ( P< 0.05). Conclusions:Compared with patients with ONFH, those with DDH demonstrate a higher prevalence of abnormal spinal-pelvic mobility, particularly a greater incidence of spinal stiffness. Among DDH subtypes, Hartofilakidis type C patients exhibit a higher proportion of abnormal mobility compared to types A and B. Additionally, patients with unilateral DDH present with greater lumbar lordosis than those with bilateral involvement.
