To characterize and identify prognostic factors for 28-day mortality among patients with hospital-acquired fungemia (HAF) in the Intensive Care Unit (ICU). ⋯ Fungi are an important cause of hospital-acquired BSI in the ICU. Patients with HAF present more frequently with septic shock and renal dysfunction on ICU admission and have a higher rate of renal failure at diagnosis. HAF are associated with a significant 28-day mortality rate (40%), but delayed adequate antifungal therapy was not an independent risk factor for death. Liver failure, need for mechanical ventilation and ICU admission for medical reason were the only independent predictors of 28-day mortality.

Growing evidence demonstrates that a number of clinical disorders may be related to genetic defects in telomere replication and extension. Overall, these syndromes are referred to as "telomeropathies" or "telomere disorders/syndromes"; they are increasingly being identified. In adulthood, idiopathic pulmonary fibrosis (IPF) is the most common symptom of telomeropathy. ⋯ In a cohort of patients addressed to lung transplantation, authors were able to demonstrate that subclinical bone marrow and liver abnormalities can be seen in patients with interstitial lung disease (ILD) and short telomeres, in some cases in the absence of clinically significant abnormalities in peripheral blood count and liver function tests. This observation sustains the rationale for further studies aimed to validate telomere length testing as a useful parameter as part of the evaluation for transplant candidacy. A deeper clarification of the complex link between IPF and short telomeres and telomeropathies is required for a new ILD classification, aimed to a fully personalized approach to the disease.

The spinal dorsal horn contains numerous inhibitory interneurons that control transmission of somatosensory information. Although these cells have important roles in modulating pain, we still have limited information about how they are incorporated into neuronal circuits, and this is partly due to difficulty in assigning them to functional populations. Around 15% of inhibitory interneurons in laminae I-III express neuropeptide Y (NPY), but little is known about this population. ⋯ Our results suggest that this input originates from a small subset of NPY-expressing interneurons, with the projection cells representing only a minority of their output. Taken together with results of previous studies, our findings indicate that somatodendritic morphology is of limited value in classifying functional populations among inhibitory interneurons in the dorsal horn. Because many NPY-expressing cells respond to noxious stimuli, these are likely to have a role in attenuating pain and limiting its spread.

Review Case ReportsCombined Fascia Iliaca and Sciatic Nerve Block for Hip Surgery in the Presence of Severe Ankylosing Spondylitis: A Case-Based Literature Review.
Selecting an appropriate anesthetic technique for patients with ankylosing spondylitis undergoing hip surgery is challenging because of a potentially difficult airway, the risk of cardiovascular and respiratory complications, and the technical difficulty of performing central neuraxial blocks in patients with ankylosing spondylitis. Our objective was to report a case in which combination neural blockade was used successfully in an elderly patient with ankylosing spondylitis undergoing hip fracture surgery. In addition, a literature review of the anesthetic techniques reported for these patients was conducted. ⋯ According to the literature review, general anesthesia is the most commonly performed anesthetic technique for patients with ankylosing spondylitis undergoing hip surgeries. Special intubation techniques and cautious airway management were very important for these patients. Although both general anesthesia and central neuraxial blockade pose considerable risks to the patients, this case report suggests that combined fascia iliaca block and sciatic nerve block might be a promising option.
