Notes

The actual Swedish open public health a reaction to COVID-19.
ersons should self-isolate immediately at the onset of COVID-like symptoms, at the time of testing as a result of a high risk exposure, or at the time of a positive test result, whichever comes first. Concurrent to isolation, all members of the household should wear a mask when in shared spaces in the household.§.Correctional and detention facilities have been disproportionately affected by coronavirus disease 2019 (COVID-19) because of shared space and movement of staff members and detained persons within facilities (1,2). During March 1-April 30, 2020, at Cook County Jail in Chicago, Illinois, >900 COVID-19 cases were diagnosed across all 10 housing divisions, representing 13 unique buildings.† Movement within the jail was examined through network analyses and visualization, a field that examines elements within a network and the connections between them. This methodology has been used to supplement contact tracing investigations for tuberculosis and to understand how social networks contribute to transmission of sexually transmitted infections (3-5). Movements and connections of 5,884 persons (3,843 [65%] detained persons and 2,041 [35%] staff members) at the jail during March 1-April 30 were analyzed. A total of 472 (12.3%) COVID-19 cases were identified among detained persons and 198 (9.7%) among staff members. Among 103,701 shared-shift connections among staff members, 1.4% occurred between persons with COVID-19, a percentage that is significantly higher than the expected 0.9% by random occurrence alone (p less then 0.001), suggesting that additional transmission occurred within this group. The observed connections among detained persons with COVID-19 were significantly lower than expected (1.0% versus 1.1%, p less then 0.001) when considering only the housing units in which initial transmission occurred, suggesting that the systematic isolation of persons with COVID-19 is effective at limiting transmission. A network-informed approach can identify likely points of high transmission, allowing for interventions to reduce transmission targeted at these groups or locations, such as by reducing convening of staff members, closing breakrooms, and cessation of contact sports.BACKGROUND The surgical strategies for posterolateral tibial plateau fractures are still inconsistent. Although a number of operative approaches were previously reported for surgical treatment of fractures of the posterolateral column in the tibial plateau, some approaches fail to provide direct visualization of the articular surface and do not allow enough space to access the posterolateral area of the lateral tibial plateau, thereby leading to unsatisfactory reconstruction of the knee and poor articular activity. MATERIAL AND METHODS We retrospectively reviewed records of 21 patients who underwent fibular neck osteotomy approach for posterolateral fractures. Radiographs taken during follow-up were used to evaluate the quality of fracture reduction and lower-limb axis. The Tegner-Lysholm score was used to assess patient functional performance. Complications, including incision infection, osteotomy nonunion, peroneal nerve injury, and fragment displacement, were evaluated. RESULTS We included 12 males and 9 females, with an age range of 27-67 years (mean age, 42.43 years). No intraoperative complications or postoperative complications were found. The mean operative duration was 128.05 min (range 86-167 min). No patients were lost to clinical or radiographic follow-up. All patients had complete follow-up (range 13-28 months, mean 19.57 months). Anatomical fracture reduction was achieved in 14 patients. Radiological limb alignment was restored in all patients. The mean Tegner-Lysholm score was 87.07 (range 74-95) and the average knee society score (KSS) was 91.67 (range 86-94) at the final follow-up. CONCLUSIONS In this retrospective study, the results suggest that the fibular neck osteotomy approach is a good choice for treatment of posterolateral tibial plateau fractures.BACKGROUND Coinfection with severe acute respiratory syndrome-associated coronavirus 2 (SARS-CoV-2) and Mycobacterium tuberculosis (MBT) has been reported, albeit rarely, in various parts of the world and has received attention from health systems because up to one-third of the world's population has been infected with SARS-CoV-2. Mexico was not included in the first-ever report on a global cohort of patients with this coinfection. We report on a case of SARS-CoV-2/MBT coinfection in a 51-year-old taxi driver from Mexico City that underscores the importance of rapid and accurate laboratory testing, diagnosis, and treatment. CASE REPORT We present the case of a man in the sixth decade of life who was admitted to the National Institute of Respiratory Diseases (INER) with a diagnosis of COVID-19 pneumonia, which was confirmed by nasopharyngeal exudate using real-time polymerase chain reaction (RT-PCR) for the identification of SARS-CoV-2. Findings from imaging studies suggested that the patient might be coinfected with MBT. That suspicion was confirmed with light microscopy of a sputum sample after Ziehl-Neelsen staining and when a Cepheid Xpert MTB/RIF assay, an automated semi-quantitative RT-PCR assay, failed to detect rifampicin resistance. The patient was discharged from the hospital 10 days later. CONCLUSIONS The present report underscores the importance of using validated molecular diagnostic tests to identify coinfections in areas where there is a high prevalence of other causes of pneumonia, such as MBT, as a way to improve clinical outcomes in patients during the COVID-19 pandemic. While it is imperative to control the COVID-19 pandemic, the medical community must not forget about the other pandemics to which populations are still prey, and tuberculosis is one of them. We must remain alert to any clinical subtleties so as to ensure timely and accurate diagnosis and stay one step ahead of COVID-19.Diabetes mellitus (DM) and atrial fibrillation (AF) are major unsolved public health problems, and diabetes is an independent risk factor for AF. However, the mechanism(s) underlying this clinical association is unknown. ROS and protein O-GlcNAcylation (OGN) are increased in diabetic hearts, and calmodulin kinase II (CaMKII) is a proarrhythmic signal that may be activated by ROS (oxidized CaMKII, ox-CaMKII) and OGN (OGN-CaMKII). We induced type 1 (T1D) and type 2 DM (T2D) in a portfolio of genetic mouse models capable of dissecting the role of ROS and OGN at CaMKII and global OGN in diabetic AF. LY3522348 clinical trial Here, we showed that T1D and T2D significantly increased AF, and this increase required CaMKII and OGN. T1D and T2D both required ox-CaMKII to increase AF; however, we did not detect OGN-CaMKII or a role for OGN-CaMKII in diabetic AF. Collectively, our data affirm CaMKII as a critical proarrhythmic signal in diabetic AF and suggest ROS primarily promotes AF by ox-CaMKII, while OGN promotes AF by a CaMKII-independent mechanism(s).
