Development of the decision-making path for utilizing stand-alone side lower back interbody fusion.
The Coronavirus Disease 2019 (COVID-19) pandemic may have altered emergency workflows established to optimize the outcome of patients with large-vessel occlusion (LVO) stroke.

We here analyzed workflow time intervals and functional outcomes of LVO patients treated with endovascular thrombectomy (ET) during the COVID-19 pandemic in Germany.

We compared the frequency, pre- and intrahospital workflow time intervals, rates of reperfusion, and functional outcome of patients admitted from March 1st to May 31st 2020 with patients admitted during the same time interval in 2019 to 12 university and municipal hospitals across Germany (
 = 795).

The number of LVO patients treated with ET between March to May 2020 was similar when compared to the same interval in 2019. Direct-to-center patients and patients admitted through interhospital transfer in 2020 showed similar pre- and intrahospital workflow time intervals compared to patients admitted in 2019, except for a longer door-to-groin time in patients admitted through interhospital transfer in 2020 (47 min vs 38 min,
 = 0.005). Rates of reperfusion were not significantly different between 2020 and 2019. Functional outcome at discharge of LVO patients treated in 2020 was not significantly different compared to patients treated in 2019.

Pre- and intrahospital workflows, ET efficacy, and functional outcome of LVO patients treated with ET were not affected during the COVID-19 pandemic in our large cohort from centers across Germany.

Questionnaires designed to assess anxiety and depression were administered on-location, and 5331 complete results were collected. SPSS software was used for statistical descriptions and analysis. Rates of anxiety disorders and depression among medical imaging workers in Shandong Province, China, were 6.1% and 6.5%, respectively, higher than those of anxiety and depression in Chinese residents before the epidemic. The outbreak in Xinjiang, China; virus mutation in Japan; and spread of the epidemic due to occupational errors were the primary reported causes of anxiety and depression among image workers. Medical imaging workers showed evidence of psychological abnormalities during the late stage of the epidemic in China.The concurrence of COVID-19 with Guillain-Barre syndrome (GBS) can increase the likelihood of neuromuscular respiratory failure, autonomic dysfunction, and other life-threatening symptoms. Currently, very little is known about the underlying mechanisms, clinical course, and prognostic implications of comorbid COVID-19 in patients with GBS. We reviewed COVID-19-associated GBS case reports published since the outbreak of the pandemic, with a database search up to August 2020, including a manual search of the reference lists for additional relevant cases. Fifty-one (51) case reports of COVID-19 patients (aged 23-84 years) diagnosed with GBS in 11 different countries were included in this review. The results revealed atypical manifestations of GBS, including para-infectious profiles and onset of GBS without antecedent COVID-19 symptoms. Although all tested patients had signs of neuroinflammation, none had SARS-CoV-2 in the cerebrospinal fluid (CSF), and only four (4) patients had antiganglioside antibodies. The majority had a 1- to 10-day time interval between the onset of COVID-19 and GBS symptoms, and many had a poor outcome, with 20 out of the 51 (39.2%) requiring mechanical ventilation, and two deaths within 12 to 24 h. The atypical manifestations of COVID-19-associated GBS, especially the para-infectious profile and short time interval between the onset of the COVID-19 and GBS symptoms, increase the likelihood of symptom overlap, which can complicate the treatment and result in worsened disease progression and/or higher mortality rates. Inclusion of a neurological assessment during diagnosis of COVID-19 might facilitate timely identification and effective management of the GBS symptoms and improve treatment outcome.A 15-year-old female with no significant past medical history who presented with abdominal pain, vomiting, and diarrhea, found to be in acute renal failure and was subsequently diagnosed with multisystem inflammatory syndrome in children (MIS-C). Critical manifestations seen in pediatric COVID-19 can be varied affecting different organ systems. Pediatric providers, during a pandemic with imperfect testing, must be keenly aware of how varied the pathogenesis of COVID-19 can be in children.In the wake of the COVID-19 pandemic, due to reasons beyond control, health care workers have struggled to deliver treatment for the patients with cancer. The concern for otherwise healthy patients with curable cancers that require timely intervention or therapy is the risk of contracting COVID-19 may outweigh the benefits of cancer treatment. Lack of international guidelines leaves health care providers with a case-to-case approach for delivering optimal cancer care in the wake of the pandemic. Transition to telemedicine has somewhat bridged the gap for in-office visits, but there is a continuing challenge of delays in cancer screening or significant decline of new diagnoses of cancers due to the pandemic. learn more We aim to propose a balance in risk from treatment delay versus risks from COVID-19 with emphasis on treatment modality (surgery, radiation, and systemic therapy) as well as supportive care for cancer patients, and therefore have reviewed the publications and recommendations from international societies and study groups available as of October 2020.Different times call for different measures. The COVID-19 pandemic has forced us to search for alternative methods to provide an annual meeting which is equally interesting and has quality. For the Belgian Society of Radiology (BSR) 2020 Annual Meeting, the sections on Abdominal Imaging, Thoracic Imaging and the Young Radiologist Section (YRS) joined forces to organize a meeting which is quite different from the ones we have organised in the past. We have chosen to create a compact - approximately 5 hour - and entirely virtual meeting with the possibility of live interaction with the speakers during the question and answer sessions. The meeting kicks off with a message from the BSR president about radiology in 2020, followed by three abdominal talks. The second session combines an abdominal talk with COVID-related talks. We have chosen to include not only thoracic findings in COVID-19, but to take it further and discuss neurological patterns, long-term clinical findings and the progress in artificial intelligence in COVID-19. Lastly, the annual meeting closes off with a short movie about the (re)discovery of Röntgens X-ray, presented to us by the Belgian Museum for Radiology, Military Hospital, Brussels.Teaching Point Dynamic ultrasound and knowledge of a clinical history of a soft-tissue lump that increases in volume upon muscle contraction or weight-bearing are crucial in the diagnosis of muscle herniation.Teaching Point Uterine involvement of B-cell acute lymphoblastic leukaemia is exceedingly rare. Globular enlargement of the uterus with diffuse homogeneous signal intensity is suggestive for the diagnosis on magnetic resonance imaging (MRI) in clinically suspected cases.Teaching Point Angiitis, an underestimated cause of stroke in HIV patients, can be diagnosed using vessel wall MRI which directly demonstrates arterial wall thickening and enhancement.
Right ventricular aneurysms (RVAs) are rare. We present a case with a combined RVA and right ventricular pericardial fistula resulting in a pericardial effusion and cardiac tamponade. The RVA was detected 47 days after the patient suffered a gunshot wound. This report adds to the body of scarce literature on RVA aetiology, diagnoses, and treatment.

A 30-year-old male patient presented with worsening respiratory distress over a 7-day period with clinical signs of cardiac tamponade following a history of a gunshot (with associated liver laceration, pulmonary embolism, right nephrectomy, and sepsis) 47 days prior. Transthoracic echocardiography showed a large circumferential pericardial effusion and an RVA. The patient was emergently taken for surgical repair of the RVA.

Our case presents a delayed presentation of a gunshot heart and an aetiology with indications of and against a true aneurysm. It brings attention to possible complications of penetrating precordial injuries, with the need for consideration and possible evaluation at follow-up. The literature on the operative excision of RVA is reviewed and various aetiological factors and consequences are discussed.

As with many novel digital biomarkers, however, rigorous evaluation is currently lacking and is required for these measures to be used effectively and safely. This paper outlines and provides examples from the literature of evaluation steps for speech-based digital biomarkers, based on the recent V3 framework (Goldsack et al., 2020). The V3 framework describes 3 components of evaluation for digital biomarkers verification, analytical validation, and clinical validation. Verification includes assessing the quality of speech recordings and comparing the effects of hardware and recording conditions on the integrity of the recordings. Analytical validation includes checking the accuracy and reliability of data processing and computed measures, including understanding test-retest reliability, demographic variability, and comparing measures to reference standards. Clinical validity involves verifying the correspondence of a measure to clinical outcomes which can include diagnosis, disease progression, or response to treatment. For each of these sections, we provide recommendations for the types of evaluation necessary for speech-based biomarkers and review published examples. The examples in this paper focus on speech-based biomarkers, but they can be used as a template for digital biomarker development more generally.The permeability of roots to water and nutrients is controlled through a variety of mechanisms and one of the most conspicuous is the presence of the Casparian strips and suberin lamellae. Roots actively regulate the creation of these structures developmentally, along the length of the root, and in response to the environment, including drought. In the current study, we characterized the suberin composition along the length of grapevine fine roots during development and in response to water deficit, and in the same root systems we quantified changes in expression of suberin biosynthesis- and deposition-related gene families (via RNAseq) allowing the identification of drought-responsive suberin-related genes. Grapevine suberin composition did not differ between primary and lateral roots, and was similar to that of other species. Under water deficit there was a global upregulation of suberin biosynthesis which resulted in an increase of suberin specific monomers, but without changes in their relative abundances, and this upregulation took place across all the developmental stages of fine roots.
