evelop effective strategies to control the disease.Bambusa intermedia Hsueh et Yi, a species in the Gramineae family, is mainly distributed in southern China and is commonly found in the Sichuan, Yunnan, and Guangdong Provinces and in the Guangxi Autonomous Region. It is economically significant as a building material, a food source, and for applications in various other raw products. In July 2017, a blight disease was found on B. intermedia stems, affecting approximately 40% of 9600 plants in the Changning and Jiangan counties of Sichuan Province, China. In the early stages of the disease, leaves at the top of the plants withered and yellowed, eventually falling off. Subsequently, the stems and upper branches discolored and were dead to varying degrees. To isolate the causal fungus, 100 samples from B. intermedia culms and branches were collected from symptomatic plants in Changning and Jiangan counties. Small sections (4 to 5 mm2) were surface-sterilized for 30 s in 3% sodium hypochlorite and 60 s in 75% ethanol. The samples were then rinsed three times in tes (2 plants per isolate in each inoculation experiment, 10 repetitions) (Li et al. 2016). Ten control plants were treated similarly except that they were mock inoculated with PDA plugs without the fungus. All plants were kept at 25-28°C and covered with plastic bags to maintain high relative humidity (90-95%) on a 12-h light/dark incubation. Thirty days later, the inoculated plants showed the same symptoms observed originally, and the controls remained healthy. The same fungus was reisolated from the infected stems and twigs and showed similar morphological characteristics and molecular traits. To our knowledge, this is the first report of A. kogelbergense as a causal agent of blight disease on B. intermedia in Sichuan Province, China.Popularity of blueberries (Vaccinium corymbosum L.) has been rising worldwide, due to their nutritional bioactive compounds such as flavonoids, anthocyanins and polyphenols (Sinelli et al. 2008). These factors led to an increase of the demand for fresh blueberries in the Czech market, which resulted in increased blueberry planted in the Czech Republic. In spring 2018, about 200,000 1-year-old blueberry plants originally from the Netherlands were planted on 47 ha in the South Moravian region. In September 2019, wilting of leaves and shoots, bark necrosis and dieback of the plant were observed. The occurrence of blueberry decline symptoms in the field was near 2% of 5,000 observed plants which resulted in significant yield losses at the beginning of the production. Twenty shoots of symptomatic plants were collected (one shoot from each plant, twenty plants in total) and surface-disinfected using 75% ethanol. Necrotic tissues of xylem were aseptically placed on potato dextrose agar (PDA) (Himedia, India) amendedlant, using a cork borer. Five shoots and pure agar plugs were used as a control. Plugs were covered with wet cotton wool to keep moisture and fixed with Parafilm. After three weeks, characteristic discoloration and lesions appeared on the inoculated shoots. Control shoots remained symptomless. Necrotic tissue was aseptically cut and L. theobromae was re-isolated on PDA. Identity of fungus was confirmed by morphological characterization and sequencing, fulfilling Koch´s postulates. Blueberry decline caused by Botryosphaeriaceae spp. has already been described around the world (Hilário et al. 2020; Tennakoon et al. 2018; Wiseman et al. 2017; Xu et al. 2015). To our knowledge, this is the first report of L. theobromae on blueberry in the Czech Republic.Clinicians currently administer patient-reported symptom scales to quantify and track concussion symptoms. These scales are based on subjective ratings without reference to the degree of functional impairment caused by the symptoms. Our objective was to develop a concussion symptom scale based on functional impairment and compare it to a widely used concussion symptom checklist. We conducted a retrospective chart review evaluating 133 patients age 9-22 with an acute concussion who completed 2 symptom checklists at their initial visit-the Sport Concussion Assessment Tool (SCAT-3) symptom evaluation (22 symptoms, 0-6 scale) and the proposed Functional Impairment Scale (22 symptoms, 0-3 scale related to degree of functional impairment). Mean total symptom score was 27.2±22.9 for Sport Concussion Assessment Tool-3 and 14.7±11.9 for the Functional Impairment Scale. Pearson correlation between the scales was 0.98 (P less then .001). Mean time from concussion to first visit was 6.9±6.2 days, and median clearance time after injury was 19 (95% CI 16-21) days. After adjusting for patient and injury characteristics, an increased score on each scale was associated with longer time to clearance (5-point increase in Sport Concussion Assessment Tool-3 hazard ratio 0.885, 95% CI 0.835-0.938, P less then .001; 2.5-point increase in Functional Impairment Scale hazard ratio 0.851, 95% CI 0.802-0.902, P less then .001). We propose a concussion symptom scale based on functional impairment that correlates strongly with the Sport Concussion Assessment Tool-3 scale, demonstrates a similar association with time to clearance, and may provide a more intuitive approach to monitoring how symptoms are affecting patients recovering from concussion. Future research should aim to validate this scale through a prospective longitudinal study.

Adult acquired flatfoot deformity is a well-known and recognized cause of pain and disability. The purpose of this retrospective study was to describe radiographic and clinical outcomes of the modified mini bone block distraction subtalar arthrodesis (SAMBB) in adult patients affected by adult flatfoot with subtalar joint osteoarthritis at a midterm mean follow-up.

A retrospective review of our database identified patients. Radiological imaging was used to evaluate angular corrections (Meary's angle [MA], talar coverage angle [TC], and calcaneal pitch angle [CP]) to assess the rate of union and highlight the possible progression of arthritis in nearby joints. Elacridar P-gp inhibitor Clinical evaluation was performed at the time of surgery and at the final follow-up using the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score. Sixty-two feet were evaluated at a mean follow-up of 6.2 ± 4.2 years.

The AOFAS score improved from a mean value of 48.1 ± 6.1 to a postoperative average score of 87.7 ± 5. CP, TC, and MA showed a postoperative improvement to 17.
