Current management of late onset neonatal bacterial sepsis in five European countries

Late onset neonatal sepsis (LOS) has a high mortality and the optimal management is poorly defined. We aimed to evaluate new expert panel-derived criteria to define LOS and characterize the current management and antibiotic susceptibility of LOS-causing organisms in Europe. A prospective observational study enrolled infants aged 4 to 90 days in five European countries. Clinical and laboratory findings as well as empiric treatment were recorded and patients were followed until the end of antibiotic therapy. Failure was defined as a change of primary antibiotic, no resolution of clinical signs, appearance of new signs/pathogens or death. Antibiotic therapy was considered appropriate if the organism was susceptible to at least one empiric antibiotic. 113 infants (median age 14 days, 62 % ≤1500 g) were recruited; 61 % were culture proven cases (28 CoNS, 24 Enterobacteriaceae, 11 other Gram-positives and 6 Gram-negative non-fermentative organisms). The predictive value of the expert-panel criteria to identify patients with a culture proven LOS was 61 % (95 % CI 52 % to 70 %). Around one third of Enterobacteriaceae were resistant to ampicillin + or cefotaxime + gentamicin but only 10 % to meropenem. Empiric treatment contained a total of 43 different antibiotic regimens. All-cause mortality was 8 % with an additional 45 % classified as failure of empiric therapy, mainly due to change of primary antibiotics (42/60). Conclusions: The expert panel—derived diagnostic criteria performed well identifying a high rate of culture proven sepsis. Current management of LOS in Europe is extremely variable suggesting an urgent need of evidence-based guidelines.     

Intraosseous hemangioma of the appendicular skeleton: imaging features of 15 cases, and a review of the literature

Objective

We performed a retrospective study of the imaging findings of 15 patients (nine female, six male, mean age 43?years) with the histopathological diagnosis of hemangioma.

Materials and methods

Radiographs, magnetic resonance imaging (MRI), computed tomography, and bone scan were performed.

Results

Lower extremity was involved in nine cases, upper extremity in three cases, the acetabulum in two cases and the ilium in one case. Fourteen of the lesions were intramedullary and one was subperiosteal. Radiographs identified the lobular osteolytic intramedullary lesions with sclerotic margins (eight cases) and coarse linear trabeculation (four cases) or matrix ossification (one case) within it or a heavily calcified lesion (one case). Lesion expanded and breached the cortical cortex in four cases. The subperiosteal hemangioma presented as a soft tissue mass with proximal periosteal reaction. MRI also identified the soft tissue mass in the case of the subperiosteal hemangioma. The CT scan demonstrated the lobular osteolytic lesions, the prominent trabeculation and matrix mineralization and evaluated the cortex. In all six cases, the lesion showed increased uptake in the bone scan.

Conclusions

This is the largest reported series of imaging features of intraosseous hemangiomas of appendicular skeleton. The lesion should be differentiated from other chondral or expansile lytic tumors. The final diagnosis can only be confirmed by histopathology.     

Single-nucleotide polymorphism rs 175080 in the MLH3 gene and its relation to male infertility

PurposeMLH3, a MutL homolog protein in mammals playing a role in DNA mismatch repair, is associated with spermatogenesis and male infertility. The purpose of the present study was to investigate the association of the single-nucleotide polymorphism (SNP), rs 175080 in the MLH3 gene, with sperm parameters in a Greek population.MethodsThe study included 300 men of couples undergoing in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) treatments (years 2011–2013). Genomic DNA was extracted from 300 peripheral blood samples, and conventional quantitative real-time PCR was performed for genotyping. Of them, 122 were from men used as “controls” and 178 from men used as “cases.” Allocation to the two groups was based on sperm concentrations (≥15 and <15 million/ml, respectively). Serum FSH, LH, estradiol, testosterone, and prolactin concentrations as well as sperm parameters were compared between three genotypes (GG, GA, and AA). Furthermore, the frequencies of these three genotypes were compared between “cases” and “controls.”ResultsAnthropometric parameters and hormonal values did not differ significantly between the three genotypes. Significantly lower sperm concentrations were found in men with the AA genotype as compared to men with the GG and GA genotypes (p < 0.001). The AA genotype had the lower progressive motility values as compared to the other two genotypes (p < 0.05). Also, there was a significantly different distribution of the frequencies of the three genotypes between “cases” and “controls” (p < 0.001).ConclusionsIt is suggested that the studied SNP in the MLH3 gene may be linked to oligozoospermia in Caucasian men of a certain area.     

Public self-consciousness,pre-loading and drinking harms among university students

Background: Social anxiety and self-consciousness are associated with alcohol-related problems in students. The practice of pre-loading is one avenue for exploration regarding this relationship. Individuals may pre-load to reduce social anxiety and feel more confident when socializing, which could lead to the increased harms experienced. The current study aimed to explore reasons for pre-loading, and whether public and private self-consciousness and social anxiety were related to pre-loading, increased drinking, and harms. Objectives: Prospective study with four-week follow up of 325 UK students aged 18-–30 years old. Participants completed measures of private and public self-consciousness, social anxiety, alcohol consumption, alcohol-related harms, and pre-loading. Results: Financial motives and mood-related reasons, such as gaining confidence were reported as reasons for pre-loading. Pre-loading predicted hazardous alcohol consumption, but social anxiety, and public and private self-consciousness did not. However, pre-loading, public self-consciousness, and social anxiety predicted alcohol-related harms. Furthermore, public self-consciousness mediated the relationship between pre-loading and harms in a positive direction and this appeared to be more relevant in high-risk (AUDIT 8+) than low-risk drinkers. Conclusions: Students who scored higher in public self-consciousness appeared to be at greater risk of harms from pre-loading. Further research should examine this relationship with particular attention to high-risk drinkers, and explore which aspects of a night out are related to heightened self-consciousness. Interventions could incorporate measures to reduce public self-consciousness, in order to reduce the negative impacts of pre-loading.     

Long-term results and competing risk analysis of the H89 trial in patients with advanced-stage Hodgkin lymphoma: a study by the Groupe d'Etude des Lymphomes de l'Adulte (GELA)

From 1989 to 1996, 533 eligible patients with stage IIIB/IV Hodgkin lymphoma (HL) were randomly assigned to receive 6 cycles of hybrid MOPP/ABV (mechlorethamine, vincristine, procarbazine, prednisone/Adriamycin [doxorubicin], bleomycin, vinblastine; n = 266) or ABVPP (doxorubicin, bleomycin, vinblastine, procarbazine, prednisone; n = 267). Patients in complete remission (CR) or partial response of at least 75% after 6 cycles received 2 cycles of consolidation chemotherapy (CT) (n = 208) or subtotal nodal irradiation (RT) (n = 210). A better survival probability was observed after ABVPP alone: the 10-year overall survival (OS) estimates were 90% for ABVPP x 8, 78% for MOPP/ABV x 8, 82% for MOPP/ABV with RT, and 77% for ABVPP x 6 with RT (P = .03); and the 10-year disease-free survival (DFS) estimates were 70%, 76%, 79%, and 76%, respectively (P = .09). The 10-year DFS estimates for patients treated with consolidation CT or RT were 73% and 78% (P = .07), and OS estimates were 84% and 79%, respectively (P = .29). These results showed that RT was not superior to consolidation CT after a doxorubicin-induced CR in patients with advanced HL. An analysis of competing risks identified age more than 45 years as a significant risk factor for death, relapse, and second cancers. Prospective evaluation of late adverse events may improve the management of patients with HL.     

Predicting febrile neutropenic patients at low risk using the MASCC score: does bacteremia matter?

Background  

Febrile neutropenic cancer patients represent a heterogeneous population with a limited proportion at risk of serious medical complications. The Multinational Association for Supportive Care in Cancer (MASCC) score has been developed and validated for identifying low-risk patients at the onset of febrile neutropenia. Since bacteremia, although not documented at baseline, is a predictor of pejorative outcome, the purpose of this study was to investigate the possible interaction between the MASCC score and bacteremic status and to assess whether, assuming that bacteremic status could be predicted at onset of febrile neutropenia, adding bacteremia as a covariate in a risk model would improve the accuracy of low-risk patients identification.     

Modifiable factors affecting inpatient violence in an acute child and adolescent psychiatric unit: A 16‐year retrospective study

Violent incidents in acute inpatient units for children and adolescents are a major and persistent problem. The demographic, clinical, and modifiable (environmental–organizational) risk factors that affect inpatient violence in an Acute Child and Adolescent Psychiatric Unit were investigated via a retrospective study. Data were collected from nursing and medical reports and the unit's census and included 100 days per year for 16 years. Incidents of violence and assault types were recorded, and variables such as the diagnostic category of assailants, total number of patients, and staffing factors during the incident were examined. Of the 2390 violent incidents recorded, 50% were attributed to cases of physical violence towards another patient, 17% to physical violence towards nursing staff, 19% to physical violence towards self and 14% to destruction of property. According to the final multivariable model, for each additional patient in the unit, the risk of a violent event increased by 9.51%; for each additional offender patient, the risk increased by 14.06%; the number of assistant nurses was associated with a 25.03% increased risk; and, after 2006, the risk increased by 68.99%. The most significant factor associated with a 59.98% decreased risk was the total number of nursing staff. All variables significantly and independently contributed to the model. Acute inpatient psychiatric units with a small number of hospitalized patients, adequate, well‐trained and specialized nursing staff, and the hospitalization of different types of patients in separate wards or units are expected to facilitate a reduction in the frequency of violent incidents.
