Timely palliative care in frail older persons remains challenging. Scales to identify older patients at risk of functional decline already exist. However, factors to predict short term mortality in older hospitalized patients are scarce.

In this prospective study, we recruited patients of 75 years and older at the department of cardiology and geriatrics. The usual gait speed measurement closest to discharge was chosen. We used the risk of dying within 1year as parameter for starting palliative care. ROC curves were used to determine the best cut-off value of usual gait speed to predict one-year mortality. Time to event analyses were assessed by COX regression.

On the acute geriatric ward (n = 60), patients were older and more frail (assessed by Katz and iADL) in comparison to patients on the cardiology ward (n = 82); one-year mortality was respectively 27 and 15% (p = 0.069). AUC on the acute geriatric ward was 0.748 (p = 0.006). The best cut-off value was 0.42 m/s with a sensitivity and specificity of 0.857 and 0.643. Slow walkers died earlier than faster walkers (HR 7.456, p = 0.011), after correction for age and sex. On the cardiology ward, AUC was 0.560 (p = 0.563); no significant association was found between usual gait speed and survival time.

Usual gait speed may be a valuable prognostic factor to identify patients at risk for one-year mortality on the acute geriatric ward but not on the cardiology ward.

Lewis-Sumner Syndrome (LSS) is considered an asymmetric sensory-motor variant of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), mostly affecting the limbs distally, with electrophysiological evidence of multifocal motor conduction blocks. Cranial nerve involvement is present in a minority. Various well-known infectious agents, directly or via the host's immune responses, may trigger or exacerbate acute and chronic peripheral neuropathies, which may manifest clinically through a multitude of signs and symptoms.

We present the case of a 57-year-old male with Lewis-Sumner Syndrome, whose clinical course was quite stable over many years. He developed severe hyperacute relapse of his neuropathic disease in the context of active pneumonia due to influenza A (H1N1) virus infection. click here During this exacerbation, besides the obvious worsening of the previous asymmetric limb involvement, the patient also manifested left peripheral facial palsy and dysphagia that rapidly evolved over minutes, mimicking a stroke. The patient also showed rapid recovery, with marked improvement of the acute neuropathic dysfunction, immediately after initiation of treatment with oseltamivir. Our hypothesis is that the direct modulation of Na + ion channel activity in the host's peripheral nerve cell by H1N1 viral proteins could cause acute and potentially reversible dysfunction in the conduction of nerve action potentials. Direct viral neuritis could also have been the cause. Immunomodulatory agents, namely IVIg, were not administered due to the swift clinical improvement noticed in the following days.

We aim to raise awareness of the possibility of atypical neurological presentations of viral infections, especially relevant in the context of the pandemic the world is now facing.

Unicondylar knee arthroplasty was introduced in the late 1960s and remains a topic of controversial discussion. Patient-specific instruments and patient-specific implants are not yet the standard of care. The question remains whether this time-consuming and costly technique can be beneficial for the patient. The aim of this study was to evaluate whether a custom-made unicondylar knee arthroplasty leads to improved patient-reported outcome.

This retrospective study evaluates the patient-reported outcome after custom-made unicondylar knee arthroplasty (CM-UKA, ConforMIS™ iUni® G2, ConforMIS Inc., Billerica, MA, USA). We evaluated 29 patients (31 knees) at an average of 2.4 years (range 1.2-3.6 years) after operation for unicondylar osteoarthritis of the knee. The target zone for the postoperative leg axis was a slight under-correction of 0-2° varus. Follow-up evaluation included the Forgotten Joint Score (FJS), the Knee Society Score (KSS), a Visual Analogue Scale (VAS) and a radiographic evaluation includiM-UKA. Further studies are needed to investigate long-term survivorship of the implant.

Small heat shock proteins (sHSPs) belong to the class of molecular chaperones that respond to biotic and abiotic stresses in plants. A previous study has showed strong induction of the gene GmHsp22.4 in response to the nematode Meloidogyne javanica in a resistant soybean genotype, while repression in a susceptible one. This study aimed to investigate the functional involvement of this small chaperone in response to M. javanica in Arabidopsis thaliana. First, it was evaluated the activation of the promoter region after the nematode inoculation, and the occurrence of polymorphisms between resistant and susceptible re-sequenced soybean accessions. Then functional analysis using A. thaliana lines overexpressing the soybean GmHsp22.4 gene, and knocked-out mutants were challenged with M. javanica infestation.

High expression levels of the GFP gene marker in transformed A. thaliana plants revealed that the promoter region of GmHsp22.4 was strongly activated after nematode inoculation. Moreover, the multiplicatioetecting cis-elements that are essential for the activation of the GmHsp22.4 gene promoter.An amendment to this paper has been published and can be accessed via the original article.
