Preserving the function of cervical disc prostheses, even over the short term, is a matter of concern among surgeons. Our case series highlights our results and protocol for increasing the probability of continued device function. Twenty-five consecutive patients with a mean (+/-SEM) age of 44.3+/-8.3 years underwent 29 cervical total disc arthroplasties for disc herniations. Three patients underwent primary bilevel arthroplasty, and one patient underwent a second arthroplasty for another herniation 2 years after the first. Prosthesis ranges of motion were measured using dynamic plain X-ray studies and compared to the ranges of motion of adjacent segments. At follow-up, all prostheses were in the correct location and without subsidence. All displayed firm secondary stability. One segment had fused. Twenty-eight of 29 devices were mobile an average of 9.5 degrees +/-4.7 degrees (range 3 degrees to 20 degrees ) (for all 29 devices the average movement angle was 9.2 degrees +/-5 degrees ; range 0 degrees to 20 degrees ), 25 upper adjacent segments were mobile an average of 10.9 degrees +/-4.5 degrees (range 2 degrees to 20 degrees ) (excluding the fused prosthesis: 11 degrees +/-4.6 degrees ) and 15 lower adjacent segments were mobile an average of 9.8 degrees +/-6 degrees (range 1 degrees to 21 degrees ). With our protocol, 28 of 29 cervical disc prostheses in 25 consecutive patients were mobile after an average of 22.3+/-9.4 months. Prosthesis motion was physiological and very similar to that of the healthy adjacent segments. Long-term studies including larger numbers of patients are required to validate our initial observations.

In the post-large era, various COVID-19 sequelae are getting more and more attention to health problems. Although the mortality rate of the COVID-19 infection is now declining, it is often accompanied by new clinical sequelae with different symptoms such as fatigue after infection, loss of smell. The degree of age, gender, virus infection seems to be weakly correlated with clinical symptoms.

Background: Little attention has been paid to the experiences of clinicians and health personnel who provide heroin-assisted treatment (HAT). This study provides the first empirical findings about the clinicians' experiences of providing HAT in the Norwegian context.
Methods: 23 qualitative interviews were conducted with 31 clinicians shortly after HAT clinics opened in Norway's two largest cities: Oslo and Bergen.

Background: As a prevalent and deadly malignant tumor, the treatment outcomes for late-stage patients with cervical squamous cell carcinoma (CSCC) are often suboptimal. Previous studies have shown that tumor progression is closely related with tumor metabolism and microenvironment reshaping, with disruptions in energy metabolism playing a critical role in this process. To delve deeper into the understanding of CSCC development, our research focused on analyzing the tumor microenvironment and metabolic characteristics across different regions of tumor tissue.

Objective: Bronchoscopy plays a critical role in the diagnosis and management of lung transplant recipients. We retrospectively evaluated the safety, complications, and efficacy of transbronchial biopsy (TBB) in detecting and grading early rejection.
Materials And Methods: We retrospectively assessed the complications associated with TBB and the adequacy of pathological diagnoses in patients who underwent lung transplantation at Koşuyolu Yüksek İhtisas Training and Research Hospital from December 1, 2016, to April 30, 2023.

Background: There is limited population-based evidence on the prevalence of cognitive impairment in Mexico, a country with a rapidly aging population and where key risk factors, such as diabetes and obesity, are common. This study describes the distribution of cognitive impairment in adults from Mexico City.
Methods: This cross-sectional population-based study included participants from the Mexico City Prospective Study which recruited 150,000 adults aged ≥ 35 years in 1998-2004.
