Association between biochemical cartilage markers and clinical symptoms in patients with hip osteoarthritis: cohort study with two-year follow-up

In order to evaluate the incidence of soft tissue changes after automated lumbar nucleotomy, a prospective cohort study was performed with follow-up CT within four to six hours after treatment of 97 discs in 88 patients. The CT scans were normal at 47 levels and abnormal at 50. At 11 levels traces of blood were seen along the trajectory, of which nine were located in the subcutaneous fat, one in the extensor and one in the psoas muscle. Small gas collections were observed at 42 levels. Twenty-one of them were located in the extensor and two in the psoas muscle, seven in the subcutaneous fat, two in the epidural space and ten in multiple locations. The abnormal scans were not associated with clinical symptoms different from those with normal scans. The results support previous reports indicating that this procedure is associated with low morbidity and complication rates.

Abstract Backgroud: To describe the frequency and distribution characteristics of gastrointestinal symptoms of coronavirus disease 2019 (COVID-19) patients.Methods: As a cohort study, all confirmed COVID-19 patients with gastrointestinal symptoms at Xiangyang No.1 people’s hospital were included until February 21st, 2020. Course of disease no less than 21 days.Gastrointestinal symptoms relevant data were extracted and analyzed. The frequency histograms of the symptoms were plotted. Main symptom characteristics were summarized.Results: Of 50 included patients with gastrointestinal symptoms, 21 were male, 29were female. The mean age was 53 (SD 16) years. Course of disease ranged from 21 to 34 days with a median of 26 days. Among all patients, 16 were critically ill and five died, 12 discharged. Thirty-one clinical symptoms occurred 3168 times in total, 6 gastrointestinal symptoms occurred 439 (13.86%) times and 25 non-gastrointestinal symptoms occurred 2 729(86.14%) times. All symptoms and non-gastrointestinal symptoms distributed in 1 to 34 days, reached peak on 6th day of follow up, first seven days were the fastigium and decreasing in the rest days. Gastrointestinal symptoms mainly distributed in 1 to 34 days, reached a peak of 36 times per day on 6th of follow-up with a fastigium during 6 to 12 day, showed a trend of rise first and then fall. Nausea, vomit and abdominal discomfort occurred 133, 70 and 62 times, respectively.Conclusions: A symptom frequency to time distribution model could describe the disease process quantitatively, indicating the change law of gastrointestinal symptoms and the organ damages in gastrointestinal system, could help us to better understand and treat the new disease. Females showed higher incidence of gastrointestinal symptoms, whether there is a sex difference in susceptibility needs to be further confirmed.Trial regitration: retrospectively registeredAuthors Guoxin Huang and Shengduo Pei contributed equally to this work.

Abstract Objectives The aims of this retrospective study were to report data on the prevalence of retrograde peri-implantitis (RPI) in a single-center in a 20-year observation period and to evaluate implant survival after surgical treatment. Materials and methods A retrospective cohort study was conducted screening all patients who underwent implant treatment in a private practice. Patients were enrolled if they had one or more implants showing a radiolucency around the implant apex, without implant mobility. Furthermore, clinical symptoms of RPI and days from symptoms’ appearance after implant placement were also collected, as well as periodontal and endodontic status of nearby teeth. All patients were treated with the same surgical approach: antibiotic therapy, mechanical curettage, chemical decontamination and xenograft application. Results Out of the 1749 implants placed, only 6 implants were classified as affected by RPI, with a prevalence of 0.34%. Clinical symptoms of RPI (pain, swelling, dull percussion or fistula presence) varied among patients and were reported after a mean period of 51.83 ± 52.43 days. Conclusions RPI was successfully treated with surgical curettage and bone substitute application and all implants are still in place after a mean follow-up of 8.83 ± 5.34 years. Clinical relevance Bacteria from teeth with failed endodontic treatment or residual lesions might be reactivated by drilling for implant osteotomy, with subsequent colonization of the implant apex and possible failure before prosthetic loading. Therefore, it might be recommended to take a periapical x-ray at implant placement and after 6–8 weeks in order to intercept RPI before prostheses delivery.
