Acute gastroenteritis outbreaks in closed and semi-closed facilities during 2017 in Catalonia,Spain

Acute gastroenteritis (AGE) is a leading cause of disease worldwide. The aim of this prospective observational study is to describe the epidemiology of AGE in closed and semi-closed institutions in Catalonia. In 2017, 151 outbreaks were reported; 30.5% occurred in closed and semi-closed institutions; 71.7% caused by norovirus (NoV) (1532) cases. Person-to-person transmission accounted for 75.8% of NoV outbreaks vs 46.1% in non-NoV outbreaks (p?<?0.001). Attack rate for NoV outbreaks was 33.1% vs 14.3% for non-NoV outbreaks (RR?=?2.3; 95%CI: 2.0–2.7). The high number of affected underscores prompt and intense preventive measures to avoid the extension and perpetuation of outbreaks in these settings.

     

Osteochondroma of the mandibular condyle: Indications for different surgical methods: A case series of 7 patients

The aim of this study was to evaluate and discuss the long-term outcomes of patients with condylar osteochondroma managed through 3 different surgical techniques.Seven patients with condylar osteochondroma treated in the author's department from May 2012 to January 2019 were included in this retrospective study. Clinical evaluations (visual analogue scale for TMJ pain, jaw function, symmetry, and quality of life), maximum interincisal opening (MIO) and radiological findings were collected pre- and postoperatively. Other parameters assessed included tumour size and location; complications and follow-up. Radical condylectomy with immediate total joint alloplastic reconstruction was performed in 4 patients, local excision in 2 patients and low condylectomy with concomitant orthognathic surgery in 1 patient. During an average follow-up period of 40,8 months no clinical or radiographic signs of recurrence were found. Average MIO increased from 25,5mm to 39,5mm at the longest follow up, and all clinical evaluations were greatly improved.In conclusion, the described surgical techniques appear valuable in the treatment of condylar osteochondroma. Local excision is indicated in tumor involving less than half the surface of the condylar head; radical condylectomy with immediate alloplastic total joint reconstruction is indicated in gigantic lesion compromising the anatomical components and function of the joint. Orthognathic surgery procedures should be combined with tumor resection when correction of associated dentofacial deformities is indicated.     

Identification of NDM-1 in a Putatively Novel Acinetobacter Species (“NB14”) Closely Related to Acinetobacter pittii

In this study, we describe the molecular characterization of a plasmid-located bla_NDM-1 harbored by an Acinetobacter clinical isolate recovered from a patient in Turkey that putatively constitutes a novel Acinetobacter species, as shown by its distinct ARDRA (amplified 16S ribosomal DNA restriction analysis) profile and molecular sequencing techniques. bla_NDM-1 was carried by a conjugative plasmid widespread among non-baumannii Acinetobacter isolates, suggesting its potential for dissemination before reaching more clinically relevant Acinetobacter species.     

Clustering of genomic breakpoints at the MLL locus in therapy‐related acute leukemia with t(4;11)(q21;q23)

Genomic characterization of translocation breakpoints is relevant to identify possible mechanisms underlying their origin. The consistent association of anthracylines (e.g., epirubicin and idarubicin) in inducing therapy‐related acute leukemias (t‐AL) with mixed lineage leukemia (MLL) gene rearrangement suggests that MLL translocations are causative events for t‐AL. Using asymmetric multiplex PCR strategy followed by direct DNA sequencing, we characterized the genomic breakpoints of the MLL and AFF1 genes in two patients who developed t‐AL with t(4;11)(q21;q23). Chemotherapeutic treatment of the primary disease in both patients included topoisomerase II (topo II) targeting agents. In one case, the MLL breakpoint was located in intron 9 at nucleotide position chr11:118354284 while the AFF1 breakpoint was in intron 3 at nucleotide position chr4:87992070. The breakpoint junction sequences revealed an insertion of two nucleotides at the MLL‐AFF1 junction. In the other patient, the MLL breakpoint was located in intron 11 at nucleotide position chr11:118359130‐32 and the AFF1 break was in intron 3 at nucleotide position chr4:87996215‐17. The MLL breakpoint found in the latter patient was identical to that of two previously reported cases, strongly suggesting the presence of a preferential site of DNA cleavage in the presence of topo II inhibitor. In addition, microhomologies at the breakpoint junctions were indicative of DNA repair by the non‐homologous end joining (NHEJ) pathway. This study further supports the evidence that MLL breakpoints in therapy‐related acute leukemia with MLL‐AFF1 are clustered in the telomeric half of the breakpoint cluster region that contains topo II recognition sites. © 2013 Wiley Periodicals, Inc.     

Differences in the use of health resources by Spanish and immigrant HIV-infected patients

Background

HIV-immigrant use of health services and related cost has hardly been analysed. We compared resource utilisation patterns and direct health care costs between Spanish and immigrant HIV-infected patients.

Methods

All HIV-infected adult patients treated during the years 2003–2005 (372 patients) in this hospital were included. We evaluated the number of out-patient, Emergency Room (ER) and Day-care Unit visits, and number and length of admissions. Direct costs were analysed. We compared all variables between immigrant and Spanish patients.

Results

Immigrants represented 12% (n = 43) of the cohort. There were no differences in the number of out-patient, ER, and day-care hospital visits per patient between both groups. The number of hospital admissions per patient for any cause was higher in immigrant than in Spanish patients, 1.3 (4.4) versus 0.9 (2.7), P = .034. A high proportion of visits, both for the immigrant (45.1%) and Spanish patients (43.0%), took place in services other than Infectious Diseases. Mean unitary cost per patient per admission, out-patient visits and ER visits were similar between groups. Pharmacy costs per year was higher in Spanish patients than in immigrants (7351.8 versus 7153.9 euros [year 2005], P = .012). There were no differences in the total cost per patient per year between both groups. The global distribution of cost was very similar between both groups; almost 75% of the total cost was attributed to pharmacy in both groups.

Conclusions

There are no significant differences in health resource utilisation and associated costs between immigrant and Spanish HIV patients.     

Influence of obesity and malnutrition on acute heart failure

Introduction and objectives

Obesity is an independent risk factor for the development of heart failure. Several recent studies have found better outcomes of heart failure for obese patients, an observation termed as the “obesity paradox.” On the other hand, the negative effect of malnutrition on the evolution of heart failure has also been clearly established.

Methods

Data from the Minimum Basic Data Set were analyzed for all patients discharged from all the departments of internal medicine in hospitals of the Spanish National Health System between the years 2006 and 2008. The information was limited to those patients with a primary or secondary diagnosis of heart failure. Patients with a diagnosis of obesity or malnutrition were identified. The mortality and readmission indexes of obese and malnourished patients were compared against the subpopulation without these diagnoses.

Results

A total of 370 983 heart failure admittances were analyzed, with 41 127 (11.1%) diagnosed with obesity and 4105 (1.1%) with malnutrition. In-hospital global mortality reached 12.9% and the risk of readmission was 16.4%. Obese patients had a lower in-hospital mortality risk (odds ratio [OR]: 0.65, 95% confidence interval [95%CI]: 0.62-0.68) and early readmission risk (OR: 0.81, 95%CI: 0.78-0.83) than nonobese patients. Malnourished patients had a much higher risk of dying while in hospital (OR: 1.83 95%CI: 1.69-1.97) or of being readmitted within 30 days after discharge (OR: 1.39, 95%CI: 1.29-1.51), even after adjusting for possible confounding factors.

Conclusions

Obesity in patients admitted for HF substantially reduces in-hospital mortality risk and the possibility of early readmission, whereas malnutrition is associated with important increases in in-hospital mortality and risk of readmission in the 30 days following discharge.Full English text available from:www.revespcardiol.org
