Flares from a candidate Galactic magnetar suggest a missing link to dim isolated neutron stars.

Magnetars are young neutron stars with very strong magnetic fields of the order of 10(14)-10(15) G. They are detected in our Galaxy either as soft gamma-ray repeaters or anomalous X-ray pulsars. Soft gamma-ray repeaters are a rare type of gamma-ray transient sources that are occasionally detected as bursters in the high-energy sky. No optical counterpart to the gamma-ray flares or the quiescent source has yet been identified. Here we report multi-wavelength observations of a puzzling source, SWIFT J195509+261406. We detected more than 40 flaring episodes in the optical band over a time span of three days, and a faint infrared flare 11 days later, after which the source returned to quiescence. Our radio observations confirm a Galactic nature and establish a lower distance limit of approximately 3.7 kpc. We suggest that SWIFT J195509+261406 could be an isolated magnetar whose bursting activity has been detected at optical wavelengths, and for which the long-term X-ray emission is short-lived. In this case, a new manifestation of magnetar activity has been recorded and we can consider SWIFT J195509+261406 to be a link between the 'persistent' soft gamma-ray repeaters/anomalous X-ray pulsars and dim isolated neutron stars.

TH-1 and TH-2 cytokines in stable chronic alcoholics.

UNLABELLED: In alcoholics, the activation of Kupffer cells by gram negative bacteriae leads to an inflammatory response and cytokine secretion, which in turn activate T-lymphocytes. Possibly, Th-1 lymphocytes are activated first, followed by a Th-2 response. Th-2 cytokines, especially interleukin (IL)-13 (scarcely studied in alcoholics), may be involved in the progression to chronic stages. AIMS: The aim of the study was to analyze the relationship of Th-1 and Th-2 cytokines with liver function, alcohol consumption, nutritional status and survival. METHODS: Serum Th-1 [interferon-γ (IFN-γ)] and Th-2 cytokines (IL-4, IL-13), IL-10, IL-6 and tumor necrosis factor (TNF-α), were determined for 18 controls and 47 stable alcoholics with variable liver function impairment, who were followed-up during a median time of 90 months, a period during which 14 patients died. RESULTS: IL-4 was lower among patients; no differences were observed regarding IL-6, but the remaining ILs were higher among alcoholics. IL-10 and IL-13 were even higher in cirrhotics (Z = 2.88, P = 0.004, and Z = 2.09, P = 0.037, respectively). A significant, direct, correlation was observed between IL-13 and IL-10 (ρ = 0.49, P = 0.001), and non-significant, inverse ones were observed between IFN-γ and IL-13 (ρ = -0.23), IL-4 (ρ = -0.14) and IL-10 (ρ = -0.09). IL-13 and IL-10 were inversely related with liver function and, directly with immunoglobulin A levels, but not with survival. CONCLUSION: Serum IFN-γ values were increased in alcoholics, who also showed raised IL-13 and IL-10, but lower IL-4 levels. Given the immunomodulatory roles of IL-10 and IL-13, this increase may be interpreted as a compensatory rise of anti-inflammatory cytokines. We failed to find any relation with mortality.

Economic impact of periprosthetic hip fractures.

INTRODUCTION: Hip replacement is one of the most successful operations in orthopaedic surgery. Periprosthetic hip fractures (PPHF) have very serious consequences for the patient, and they also entail a very important economic impact on healthcare systems. The aim of the study was to provide the first detailed cost analysis of PPHF in a traumatology and orthopaedics service in a third level hospital in Spain. METHODS: The study included all patients admitted between 2009 and 2019 with a diagnosis of "PPHF". We assessed hospital stay cost, total cost of the operating theatre, cost of the implants used, analyses, consultations with other specialists, rehabilitation sessions, radiological tests, microbiology, blood transfusions and other surgical operations during the same admission. RESULTS: 78 patients were included in the study, 49 women and 29 men, with a mean age of 78.74 years (R 45-92). 69 patients received surgical treatment, 75% had open reduction and internal fixation (ORIF), and 25% had revision surgery. The total cost was €1,139,650.17. The average cost was €14,610.90. Significantly higher costs were incurred for revision compared to ORIF treatments, admissions that lasted more than 30 days, and patients who required more than one operation during admission. The most costly factors were the hospital stay (46%), the cost of the surgery itself (35%), and the implants (24%). CONCLUSIONS: Revision arthroplasty versus ORIF treatment, admissions lasting more than 30 days, and patients requiring more than one operation on admission incurred significantly higher costs. The average cost, from a hospital perspective, generated by a PPHF was €14,610.90. The most costly factors were, in descending order, the hospital stay, the cost of the surgery itself, and the implants. It is necessary to establish protocols and updated therapeutic algorithms in the perioperative management of PPHF in order to reduce both morbidity rates and associated costs.

Ternary copper(II) complexes with N-carboxymethyl-l-prolinato(2-) ion and imidazole or creatinine: a comparative study of the interligand interactions influencing the molecular recognition and stability.

The compounds {[Cu(CMP)(Him)].H(2)O}(n) (I) and [Cu(CMP)(crea)H(2)O].3H(2)O (II) were synthesized and characterized by X-ray diffraction, thermal, spectral and magnetic methods (CMP=N-carboxymethyl-;l-prolinato(2-) ion, Him=imidazole and crea=creatinine). Appropriate structural comparison with other compounds such as {[Cu(CMP)(H(2)O)].H(2)O}(n), [Cu(crea)(2)Cl(2)] and [Cu(dipeptide)(crea)(H(2)O)(x)].nH(2)O (x=0 or 1) have been made in order to prove that crea can act as an imidazole-like ligand (because it is able to promote the same fac- to mer-CMP tridentate conformational change in copper(II) complexes) as well as to discuss the interligand interactions which control the 'Cu(CMP) complex-crea, molecular recognition processes. In contrast to that found in related ternary complexes, we have concluded that direct CMP-crea interligand interactions are missing in the Cu-CMP-crea complex due to the inappropriate correspondence between the donor and/or acceptor H-bonding properties of these ligands. CMP can only act as H-acceptor by its two terminal carboxylate group, and crea can display H-donor and H-acceptor roles by its exocyclic -NH(2) and O moieties, respectively. That promotes the reinforcement of the Cu-N(crea) bond by a bridge -N-H(crea)...O(aqua) (2.867(3)A, 176.4 degrees).

[Suspicion of metastases in laryngeal carcinomas]. / Predicción de la capacidad metastásica del cáncer de laringe: implicaciones clínicas.

OBJECTIVE: To look for models predicting metastasis in laryngeal/hypopharyngeal carcinomas. DESIGN: Prospective study. PATIENTS: Sixty patients bearing laryngeal squamous cell carcinoma who were treated with curative purposes were followed prospectively with at least 10-year follow-up. PARAMETERS: Clinical (Staging, site, age, alcohol and smoking intake, surgery on the primary tumor, neck surgery) and pathological (size, number of metastatic lymph nodes, T and N staging, degree of differentiation, Jakobsson's and Glanz's scoring of malignancy, both scores in biopsies and surgical specimens) parameters were recorded in each case. METHODS: A multivariate analysis was performed to find out those parameters independently related to presence of metastases. RESULTS: The prospective study rendered tumor burden and Glanz's scoring from biopsies to be independently related with the presence of metastases. CONCLUSIONS: Malignancy grading systems must be included in laryngeal carcinoma patients' planning of neck treatment.

[Treatment of laryngeal granuloma with anti-extraesophageal reflux medication]. / Tratamiento de los granulomas de laringe con medicación anti-reflujo extraesofágico.

OBJECTIVE: To asses the role of Gastroesophageal reflux in the genesis of laryngeal granulomas. PATIENTS AND METHODS: Prospective series of 7 patients diagnosed of posterior laryngeal granuloma, 5 were male, and 2 female, ages ranging between 46 and 65 years, (only three with symptoms of gastroesophageal reflux), who followed an antireflux protocol (recommendations, omeprazol 20 mg, cisapride 20 mg, almagato 4000 mg daily). RESULTS: All cases did well, showing complete healing of the larynx 60 days after the beginning of treatment. CONCLUSIONS: Gastroesophageal reflux is an important factor in the genesis of posterior laryngeal granulomas. It seems appropriate to start an antireflux regimen before surgery, which can be chosen for non responders or cases with severe respiratory symptoms, hoarseness, or for definitive diagnosis.

The leprosy is a chronic illness caused by M. leprae, which affects mucosa mainly at the level of the nasal region. The important destruction of the bone produces the facies leonina. We present the case of a patient with nasal leprosy, describing the clinical characteristics and the diagnostic and therapeutic methods that were carried out on her.

Relative and combined effects of selenium, protein deficiency and ethanol on hepatocyte ballooning and liver steatosis.

Oxidative damage plays a key role in alcohol-mediated liver alterations. Selenium, a potent antioxidant, is decreased in alcoholics. This study was conducted to analyse if the supplementation with selenium may alter liver changes in a murine model fed ethanol and/or a 2 % protein-containing diet, following the Lieber-DeCarli design. Adult male Sprague Dawley rats were divided into eight groups which received the Lieber-DeCarli control diet; an isocaloric, 36 % ethanol-containing diet; an isocaloric, 2 % protein-containing diet; and an isocaloric diet containing 2 % protein and 36 % ethanol diet; and other similar four groups to which selenomethionine (1 mg/kg body weight) was added. After sacrifice (5 weeks later), liver fat amount and hepatocyte areas of pericentral and periportal cells were measured, and liver and serum selenium, activity of liver glutathione peroxidase (GPX), and liver malondialdehyde were determined. Ethanol-fed rats showed increased hepatocyte areas and fat accumulation especially when ethanol was added to a 2 % protein diet. Selenium caused a decrease in hepatocyte ballooning and liver fat amount, but an increase in GPX activity, and a marked increase in serum and liver selenium. The present study demonstrates that selenium, added to the diet of rats in the form of seleniomethionine, prevents the appearance of early signs of ethanol-mediated liver injury under the conditions of the Lieber-DeCarli experimental design.

Malignant melanomas of the nasolacrimal duct.

Two patients with a history of epistaxis who were both found to have a nasolacrimal duct melanoma are presented. A literature review revealed that no previous cases of primary nasolacrimal duct melanoma have been reported. Current therapeutic modalities are discussed.

Intramolecular "Aryl-metal chelate ring" pi,pi-interactions as structural evidence for metalloaromaticity in (aromatic alpha,alpha'-diimine)-copper(II) chelates: molecular and crystal structure of aqua(1,10-phenanthroline)(2-benzylmalonato)copper(II) three-hydrate.

By reaction of Cu(2)CO(3)(OH)(2), 2-benzylmalonic acid (H(2)Bzmal), and 1,10-phenanthroline (phen), [Cu(Bzmal)(phen)(H(2)O)] x 3H(2)O (compound 1) has been obtained and characterized by thermal, spectral, magnetic, and X-ray diffraction methods. The molecular structure of 1 is remarkably similar to that of [Cu(Bzmal)(bipy)(H(2)O)] x 2H(2)O (compound 2, bipy = 2,2'-bipyridine). In both complexes, the aryl(Bzmal) ring produces an unexpected pi,pi-stacking interaction with the Cu(II)-(aromatic alpha,alpha'-diimine) chelate ring, at an average distance d(pi)(-)(pi) of 3.40 A, involving roughly parallel and smoothly slipped rings. This insight is discussed as new structural evidence for metalloaromaticity of Cu(II)-(aromatic alpha,alpha'-diimine) chelate rings. Interestingly, 1 recognizes itself by a weak intermolecular pi,pi-stacking interaction between aryl(Bzmal) ligands to give pairs of complex molecules. In contrast, there is an intermolecular pyridyl-pyridyl pi,pi-stacking interaction also forming pairs of complex molecules in 2.
