Situation Report-51 SITUATION IN NUMBERS total and new cases in last 24 hours Globally 118 319 confirmed (4620 new) 4292 deaths (280 new) China 80 955 confirmed (31 new) 3162 deaths (22 new) Outside of China 37 364 confirmed (4589 new) 1130 deaths (258 new) 113 countries/territories/ areas (4 new) WHO RISK ASSESSMENT China Very High Regional Level Very High Global Level Very High HIGHLIGHTS • WHO Director-General in his regular media briefing today stated that WHO has been assessing this outbreak around the clock and we are deeply concerned both by the alarming levels of spread and severity, and by the alarming levels of inaction. WHO therefore have made the assessment that COVID-19 can be characterized as a pandemic. For detailed information, please see here. • Four new countries/territories/areas (Bolivia [Plurinational State of], Jamaica, Burkina Faso and Democratic Republic of the Congo) have reported cases of COVID-19 in the past 24 hours. • The COVID-19 virus infects people of all ages. However, evidence to date suggests that two groups of people are at a higher risk of getting severe COVID-19 disease. These are older people; and those with underlying medical conditions. WHO emphasizes that all must protect themselves from COVID-19 in order to protect others. For more information, please see 'subject in focus'. • On 10 March, the IFRC, UNICEF and WHO issued a new guidance to help protect children and schools from transmission of the COVID-19 virus. The guidance provides critical considerations and practical checklists to keep schools safe. More information can be found here. Figure 1. Countries, territories or areas with reported confirmed cases of COVID-19, 11 March 2020 Erratum: 'Total cases' and 'new cases' for Bulgaria and Paraguay have been corrected. SUBJECT IN FOCUS: Risk Communication guidance-COVID-19, older adults and people with underlying medical conditions The virus that causes COVID-19 infects people of all ages. However, evidence to date suggests that two groups of people are at a higher risk of getting severe COVID-19 disease. These are older people (that is people over 60 years old); and those with underlying medical conditions (such as cardiovascular disease, diabetes, chronic respiratory disease, and cancer). The risk of severe disease gradually increases with age starting from around 40 years. It's important that adults in this age range protect themselves and in turn protect others that may be more vulnerable. WHO has issued advice for these two groups and for community support to ensure that they are protected from COVID-19 without being isolated, stigmatized, left in a position of increased vulnerability or unable to access basic provisions and social care. This advice covers the subject of receiving visitors, planning for supplies of medication and food, going out safely in public and staying connected with others through phone calls or other means. It is essential that these groups are supported by their communities during the COVID-19 outbreak. WHO emphasizes that all people must p...
In 1975, Blake and McBryde established the concept of ‘floating knee’ to describe ipsilateral fractures of the femur and tibia.1 This combination is much more than a bone lesion; the mechanism is usually a high-energy trauma in a patient with multiple injuries and a myriad of other lesions.After initial evaluation patients should be categorised, and only stable patients should undergo immediate reduction and internal fixation with the rest receiving external fixation.Definitive internal fixation of both bones yields the best results in almost all series.Nailing of both bones is the optimal fixation when both fractures (femoral and tibial) are extra-articular.Plates are the ‘standard of care’ in cases with articular fractures.A combination of implants are required by 40% of floating knees.Associated ligamentous and meniscal lesions are common, but may be irrelevant in the case of an intra-articular fracture which gives the worst prognosis for this type of lesion.Cite this article: Muñoz Vives K, Bel J-C, Capel Agundez A, Chana Rodríguez F, Palomo Traver J, Schultz-Larsen M, Tosounidis, T.

Atraumatic subtrochanteric and diaphyseal (atypical) femoral fractures are a rare, but important adverse event in patients treated with potent anti-resortive agents. The mechanisms involved are unknown and particularly the association with genetic variants has not been explored. The aim of the study was to identify rare genetic variants that could be associated with the occurrence of these fractures. We performed a genome-wide analysis of up to 300,000 variants, mainly distributed in gene coding regions, in 13 patients with atypical femoral fractures and 268 control women, either healthy or with osteoporosis. Twenty one loci were more frequent in the fracture group, with a nominal p value between 1 × 10(-6) and 2.5 × 10(-3). Most patients accumulated two or more allelic variants, and consequently the number of risk variants was markedly different between patients and controls (p = 2.6 × 10(-22)). The results of this pilot study suggest that these fractures are polygenic and are associated with the accumulation of changes in the coding regions of several genes.
To support the global restart of elective surgery, data from an international prospective cohort study of 8492 patients (69 countries) was analysed using artificial intelligence (machine learning techniques) to develop a predictive score for mortality in surgical patients with SARS-CoV-2. We found that patient rather than operation factors were the best predictors and used these to create the COVIDsurg Mortality Score (https://covidsurgrisk.app). Our data demonstrates that it is safe to restart a wide range of surgical services for selected patients.
Background: The Trauma Expectation Factor Trauma Outcomes Measure (TEFTOM) questionnaire is a self-administered, patient-rated outcome measurement questionnaire designed to measure both ‘expectation’ and ‘outcome’ in orthopaedic trauma patients using two subsets of 10 items. We aimed to validate this instrument in a culturally diverse cohort of patients recruited from Asian and European regions. Methods: A total of 193 adult patients with surgically treated AO Foundation/Orthopaedic Trauma Association types 43 and 44 ankle malleolar and distal tibia fractures were recruited with 158 followed up till 1 year. Expectations were assessed prior to surgery, at 2 weeks and after 6 months using the trauma expectation factor (TEF) score. Outcomes were evaluated at 2 weeks, 6 and 12 months using the trauma outcome measure (TOM), American Academy of Orthopaedic Surgeons (AAOS), foot and ankle outcome score (FAOS) and short form-36 (SF-36) questionnaires. Psychometric properties of TEFTOM were assessed. Results: TEF and TOM demonstrated good internal consistency (Cronbach’s α > 0.87) and reliability at all time points (intra-class correlation coefficients > 0.90). TOM showed strong correlations ( R 2 ≥ 0.60) with the AAOS foot and ankle score, all FAOS subscales, except ‘symptoms’ and SF-36 physical functioning, role physical, bodily pain, social functioning and the physical component summary at 6 and 12 months. Effect sizes for TOM were 2.30 and 0.74 from 2 weeks to 6 months and from 6 months to 12 months, respectively. The baseline patient TEF was predictive for the 1-year TOM score. Conclusions: TEFTOM demonstrated good psychometric properties in this cohort of patients with ankle fractures. The TEF ‘expectation’ score was predictive of the TOM ‘outcome’ score. We recommend researchers and clinicians to utilize TEFTOM when patient expectation measurement is concerned for orthopaedic trauma patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
