Autism,epilepsy, and synaptopathies: a not rare association

Autism spectrum disorders (ASD) are neurodevelopmental disorders typically diagnosed in childhood, characterized by core social dysfunction, rigid and repetitive behaviors, restricted interests, and abnormal sensorial sensitivity. ASD belong to multifactorial diseases: both genetic and environmental factors have been considered as potential risk factors for their onset. ASD are often associated with neurological conditions: the co-occurrence of epilepsy is well documented and there is also evidence of a higher prevalence of EEG abnormalities with 4–86% of individuals with ASD presenting epileptiform or not epileptiform EEG abnormalities. The presence of epilepsy in people with ASD may be determined by several structural alterations, genetic conditions, or metabolic dysfunctions, known to play a role in the emergence of both epilepsy and autism. The purpose of this article is to discuss precisely such latter cause of the autism–epilepsy association, focusing specifically on those “synaptic genes,” whose mutation predisposes to both the diseases.     

A systematic review of spleen and pancreas preservation in extended lymphadenectomy for gastric cancer

Background

The overall prognosis and survival of patients with advanced gastric cancer are generally poor. Extended lymphadenectomy is recommended for patients with advanced gastric cancer; however, splenectomy and distal pancreatectomy performed with an extended lymph node dissection may be associated with increased morbidity and mortality.

Method

Electronic literature searches were conducted using Medline, Embase, and the Cochrane Central Register of Controlled Trials from 1 January 1998 to 31 December 2009. Studies on gastric carcinoma investigating extended lymphadenectomy with splenectomy and/or pancreaticosplenectomy that reported data on surgical outcomes or survival were selected.

Results

Forty studies were included in this review. Decreased complication rates were demonstrated with spleen preservation in two prospective studies and three retrospective studies, and with pancreas preservation in five retrospective studies. No randomized controlled trial showed survival benefit or detriment for preservation of spleen or pancreas in extended lymphadenectomy. Improved survival was demonstrated with spleen preservation in two prospective and eight retrospective studies, and with pancreas preservation in one prospective and four retrospective studies.

Conclusions

Preservation of the spleen and pancreas during extended lymphadenectomy for gastric cancer decreases complications with no clear evidence of improvement or detriment to overall survival.

Assessing predictive validity of the modified Braden scale for prediction of pressure ulcer risk of orthopaedic patients in an acute care setting

Aims and objectives. To assess and compare the predictive validity of the modified Braden and Braden scales and to identify which of the modified Braden subscales are predictive in assessing pressure ulcer risk among orthopaedic patients in an acute care setting. Background. Although the Braden scale has better predictive validity, literature has suggested that it can be used in conjunction with other pressure ulcer risk calculators or that some other subscales be added. To increase the predictive power of the Braden scale, a modified Braden scale by adding body build for height and skin type and excluding nutrition was developed. Design. A prospective cohort study. Method. A total of 197 subjects in a 106‐bed orthopaedic department of an acute care hospital in Hong Kong were assessed for their risk for pressure ulcer development by the modified Braden and Braden scales. Subsequently, daily skin assessment was performed to detect pressure ulcers. Cases were closed when pressure ulcers were detected. Results. Out of 197 subjects, 18 patients (9·1%) developed pressure ulcers. The area under the receiver operating characteristic curve for the modified Braden scale was 0·736 and for the Braden scale was 0·648. The modified Braden cut‐off score of 19 showed the best balance of sensitivity (89%) and specificity (62%). Sensory perception (Beta = ?1·544, OR=0·214, p = 0·016), body build for height (Beta = ?0·755, OR = 0·470, p = 0·030) and skin type (Beta = ?1·527, OR = 0·217, p = 0·002) were significantly predictive of pressure ulcer development. Conclusion. The modified Braden scale is more predictive of pressure ulcer development than the Braden scale. Relevance to clinical practice. The modified Braden scale can be adopted for predicting pressure ulcer development among orthopaedic patients in an acute care setting. Specific nursing interventions should be provided, with special attention paid to orthopaedic patients with impaired sensory perception, poor skin type and abnormal body build for height.     

Evolution of pattern of breathing during a spontaneous breathing trial predicts successful extubation

Purpose  

Rapid shallow breathing may occur at any time during spontaneous breathing trials (SBT), questioning the utility of a single determination of the rapid shallow breathing index (RSBI). We hypothesize that change in RSBI during SBT may more accurately predict successful extubation than a single determination.     

Quality Measures for Supportive Cancer Care: The Cancer Quality-ASSIST Project

Patients and physicians often cite symptom control as one of their most important goals in cancer care. Despite this, a previous systematic review found few tools for evaluating the quality of supportive cancer management. We developed a comprehensive set of quality indicators for evaluating pain and nonpain symptom management as well as care planning needs in cancer patients. Based on the prevalence and quality-of-life data, clinician-researchers prioritized pain, psychosocial distress, dyspnea, nausea and vomiting, fatigue and anorexia, treatment-associated toxicities, and information and care planning for quality-indicator development. Using search terms and selection criteria, we identified English-language documents from Medline (1997–2007) and Internet-based searches. Based on this evidence, clinician-reviewers proposed process quality indicators. We then used the VA Health Services Research and Development (VA HSR & D) appropriateness methods to compile the ratings of a multidisciplinary, international expert panel of the validity and feasibility of each indicator. The panel judged 92 out of 133 (69%) proposed quality indicators valid and feasible (15 out of 23 pain, 5 out of 6 depression, 8 out of 11 dyspnea, 15 out of 19 nausea and vomiting, 13 out of 26 fatigue and anorexia, 23 out of 32 other treatment-associated toxicities, and 13 out of 16 information and care planning). Of the final indicators, 67 are potentially useful for inpatient and 81 for outpatient evaluation, and 26 address screening, 12 diagnostic evaluation, 20 management, and 21 follow-up. These quality indicators provide evidence-explicit tools for measuring processes critical to ensuring high-quality supportive cancer care. Research is needed to characterize adherence to recommended practices and to evaluate the use of these measures in quality improvement efforts.     

Zoonotic potential of multidrug-resistant extraintestinal pathogenic Escherichia coli obtained from healthy poultry carcasses in Salvador,Brazil

The zoonotic potential to cause human and/or animal infections among multidrug-resistant extraintestinal pathogenic Escherichia coli from avian origin was investigated. Twenty-seven extraintestinal pathogenic E. coli isolates containing the increased survival gene (iss) were obtained from the livers of healthy and diseased poultry carcasses at two slaughterhouses in Salvador, northeastern Brazil. The antimicrobial resistance-susceptibility profiles were conducted with antibiotics of avian and/or human use by the standardized disc-diffusion method. Antimicrobial resistance was higher for levofloxacin (51.8%), amoxicillin/clavulanic acid (70.4%), ampicillin (81.5%), cefalotin (88.8%), tetracycline (100%) and streptomycin (100%). The minimum inhibitory concentrations above the resistance breakpoints of doxycycline, neomycin, oxytetracycline and enrofloxacin reached, respectively, 88.0%, 100%, 75% and 91.7% of the isolates. Strains with high and low antimicrobial resistance were i.p. administered to Swiss mice, and histopathological examination was carried out seven days after infection. Resistance to goat and human serum complement was also evaluated. The results show that Swiss mice challenged with strain 2B (resistant to 11 antimicrobials) provoked a severe degeneration of hepatocytes besides lymphocytic infiltration in the liver, whereas the spleen showed areas of degeneration of the white and red pulp. Conversely, the spleen and liver of mice challenged with strain 4A (resistant to two antimicrobials) were morphologically preserved. In addition, complement resistance to goat and human serum was high for strain 2B and low for strain 4A. Our data show that multidrug resistance and pathogenesis can be correlated in extraintestinal pathogenic E. coli strains obtained from apparently healthy poultry carcasses, increasing the risk for human public healthy.
