A key question concerning coronavirus disease 2019 (COVID-19) is how effective and long lasting immunity against this disease is in individuals who were previously infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We aimed to evaluate the risk of SARS-CoV-2 re-infections in the general population in Austria.

This is a retrospective observational study using national SARS-CoV-2 infection data from the Austrian epidemiological reporting system. As the primary outcome, we aim to compare the odds of SARS-CoV-2 re-infections of COVID-19 survivors of the first wave (February to April 30, 2020) versus the odds of first infections in the remainder general population by tracking polymerase chain reaction (PCR)-confirmed infections of both groups during the second wave from September 1 to November 30, 2020. Re-infection counts are tentative, since it cannot be excluded that the positive PCR in the first and/or second wave might have been a false positive.

We recorded 40 tentative re-infections in 14840 COVID-19 survivors of the first wave (0.27%) and 253581 infections in 8885640 individuals of the remaining general population (2.85%) translating into an odds ratio (95% confidence interval) of 0.09 (0.07 to 0.13).

We observed a relatively low re-infection rate of SARS-CoV-2 in Austria. Protection against SARS-CoV-2 after natural infection is comparable with the highest available estimates on vaccine efficacies. Further well-designed research on this issue is urgently needed for improving evidence-based decisions on public health measures and vaccination strategies.

Failing conservative therapies, uterine artery embolisation (UAE) has been proposed as a uterine-sparing option for treatment of symptomatic adenomyosis. UAE appears effective at short-term; however long-term durability is less well established.

To evaluate the long-term clinical efficacy of UAE for treatment of adenomyosis.

One hundred and four women with initial clinical success following UAE for adenomyosis (results previously published) were further followed with a two-part online survey. Part one inquired about menopause, symptom recurrence, need for further intervention and overall satisfaction. Part two comprised the Uterine Fibroid Symptom and health-related Quality of Life (UFS-QOL) questionnaire. selleck products Maintenance of clinical success was defined as remaining 'happy' or 'very happy' with overall outcome, no recurrence of symptoms, or need for further intervention.

Of those women with initial success, 91/104 (88%) participated in this long-term study at mean 52months following UAE. Maintenance of clinical success was demonstrated in 82/91 (90%) women. For the remaining 9/91 (10%) women, mean time to failure was 31months. There were 53/91 (58%) women who reached menopause at mean age of 51.5years, occurring at mean 30months post-UAE. UFS-QOL demonstrated significant decrease in symptom severity from 58.9 to 20.0 (P<0.001); and significant increase in QOL from 40.3 to 86.3 (P<0.001).

Long-term durability of UAE for treatment of adenomyosis was demonstrated, with cumulative success rate of 80% at mean 52months. UAE did not appear to bring forward menopause. UAE should be considered as an alternative to hysterectomy to treat adenomyosis.

In the present study we evaluated measurement techniques for standard metabolic rate (SMR), maximum metabolic rate (MMR) and aerobic scope in an Acipenseriform, the lake sturgeon Acipenser fulvescens, throughout the first year of life. Standardized forced exercise protocols to assess MMR were conducted for 5 or 15 min before or after measurement of SMR. We used different levels of oxygen decline during the measurement period of MMR post forced exercise to understand the influence these may have on the calculation of MMR. Opercular rate and tail beat frequencies were recorded by video as measures of behaviours and compared to metabolic rate recorded over a 24 h period. Results indicate that calculated values for aerobic scope were lower in younger fish. Neither exercise sequence nor exercise duration influenced metabolic rate measurements in the younger fish, but exercise duration did affect measurement of MMR in older fish. Finally, there was no strong correlation between metabolic rate and the measured behaviours in the lake sturgeon at either age. link2 Based on the results, we recommend that a minimum of 6 h of acclimation to the respirometry chamber should be given prior to measuring SMR, a chasing protocol to elicit MMR should ideally be performed at the end of experiment, a short chasing time should be avoided to minimize variation and assessment of MMR should balance measurement limitations of the probes along with when and for how long oxygen consumption is measured.A vital and healthy dental pulp (DP) is required for teeth to remain functional throughout a lifespan . Appreciating its value for the tooth, the regeneration of the DP is a highly researched goal. While inflammation of the DP marks the beginning of an eventual necrosis, it is also the prerequisite for the regenerative events of neovascularisation, stem cells mobilisation and reparative dentine deposition. In the light of a pro-regenerative inflammatory process, the present review discusses the role of macrophage population shift from pro- to anti-inflammatory in reversible versus irreversible pulpitis, while also analysing the overlooked contribution of pulp innervation and locally derived neuropeptides to the process. Then, the currently practiced (pulp capping and revascularisation) and researched (cells transplantation and cell homing) approaches for DP regeneration are discussed. Focusing on the role of cell homing in modulating inflammation, some potential strategies are highlighted to harness the inflammatory process for DP regeneration, mainly by reversing inflammation through macrophage induction. Next, some potential clinical applications are discussed - especially with capping materials - that could boost macrophage polarisation and complement system activation. Finally, current challenges facing the regeneration of the DP are presented, while underlining the importance of promoting an anti-inflammatory environment conducive to a regenerative process.

 Kyphosis is the most common deformity of the cervical spine leading to development of severe disabilities. In case of fused kyphosis, surgical treatment can be demanding and often requires multiple-step procedures for adequate correction. link3 We present a technique of single-stage pedicle subtraction osteotomy (PSO) of C3 to treat a patient with fused kyphosis of C2 and C3 causing spinal stenosis with subsequent myelopathy.

 A 53-year-old man presented with progressive myelopathy not able to walk with 6/18 points on the modified Japanese Orthopedic Association scale. Horizontal gaze was lost due to cervical kyphosis. Magnetic resonance imaging (MRI) revealed a cervical kyphosis causing stenosis, cord compression, and kinking; computed tomography (CT) showed substantial anterior and posterior fusion of C2 and C3.

 Surgery included decompression via laminectomy of C2 to C6 in combination with PSO of C3 and additional dorsal instrumentation of C2 to C6. Cervical spinal alignment was corrected, as the C2-C4 Cobb angle was reduced from 48.9 to 20.6 degrees. Horizontal gaze was restored. Postoperative MRI demonstrated full decompression of the cord without kinking of the vertebral arteries. No complications were noted. The patient recovered well with restoration of his ability to walk.

 Single-stage pedicle subtraction closing wedge osteotomy in the upper cervical spine, although a demanding surgical procedure, is an alternative treatment option in selected cases of fused and severe cervical kyphosis. In contrast to multiple-step approaches, the single-stage procedure could reduce operating time and may thus decrease complications.

 The human brain, depending on aerobic glycolysis to cover its metabolic needs and having no energy reserves whatsoever, relies on a constant and closely regulated blood supply to maintain its structural and functional integrity. Cerebral autoregulation, that is, the brain's intrinsic ability to regulate its own blood flow independently from the systemic blood pressure and cardiac output, is an important physiological mechanism that offers protection from hypoperfusion injury.

 Two major independent mechanisms are known to be involved in cerebral autoregulation (1) flow-metabolism coupling and (2) myogenic responses of cerebral blood vessels to changes in transmural/arterial pressure. A third, less prominent component of cerebral autoregulation comes in the form of neurogenic influences on cerebral vasculature.

 Although fragmentation of cerebral autoregulation in separate and distinct from each other mechanisms is somewhat arbitrary, such a scheme is useful for reasons of simplification and to better understand their overall effect. Comprehension of cerebral autoregulation is imperative for clinicians in order for them to mitigate consequences of its impairment in the context of traumatic brain injury, subarachnoid hemorrhage, stroke, or other pathological conditions.

 Complete microsurgical clip occlusion of an aneurysm is one of the most important challenges in cerebrovascular surgery. Incorrect position of clip blades as well as intraoperative aneurysm rupture can expose the patient to serious complications such as rebleeding in case of aneurysm remnant and cerebral ischemia in case of occlusion of branching arteries or perforators. The aim of this study was to identify independent predictors of surgery-derived complications (aneurysm remnant and brain ischemia) as well as intraoperative aneurysm rupture in an institutional series of patients.

 This is a single-institution, retrospective cohort study including 147 patients with 162 aneurysms that were selected for microsurgical clipping due to intracranial aneurysm in a 5-year period. Bivariate and multivariate analyses were performed to identify independent predictors among demographic, clinical, and radiographic factors.
