RESUMO
This study assessed the provision of education and support to parents of children on home enteral nutrition (HEN), current dietetic support available and perceived challenges facing parents and carers. From the 39 responses (13%), 29 (83%, n = 35) parents suggested services for HEN need improvement. 29 (74%, n = 39) parents wanted more structured follow up and 22 (56%) would like one person to co-ordinate HEN, education and discharge. 7 parents (18%) reported a need for further education of health care professionals (HCP). Hospital dietitians were the most common HCPs reported to provide support to patients following discharge. Specialist paediatric HEN dietetic services working in a dedicated HEN team, who would provide accurate training and education and liaise with both parents and community care services post discharge should be in place. This would facilitate transfer to community care, reduce hospital re-admissions, outpatient department attendances and costs.

In 2016, bluetongue virus (BTV), serotype 16 (BTV-16), was detected in New South Wales (NSW) in sentinel cattle for the first time. Over the next 6 years, BTV-16 has been detected regularly and over an increasing area of the BTV zone in NSW. In April 2023, disease was reported in sheep on two farms on the Northern Tablelands of NSW. The consistent clinical signs included reduced exercise tolerance, facial swelling, serous nasal discharges with encrustation of the nasal plane, subcutaneous oedema of the neck and brisket and variable congestion of the coronary band. Affected sheep were mainly mature ewes and rams, with an estimated morbidity of 20% over a period of 6-8 weeks. Although there were several unexpected deaths, no veterinary examination was sought. Predominantly BTV-16 RNA was detected in sick sheep, with an incidence of infection of approximately 40% in a cross section of one flock. These events represent the first confirmation of disease due to bluetongue virus in NSW. As these cases occurred in a region with a high density of sheep, if there is ongoing transmission of BTV-16 during subsequent summers, further disease might be expected.

INTRODUCTION: Civilian-military relations play an important yet under-researched role in low-income and middle-income country epidemic response. One crucial component of civilian-military relations is defining the role of the military. This paper evaluates the role of Nigerian military during the 2014-2016 West African Ebola epidemic. METHODS: Focus groups and key informant interviews were conducted throughout three states in North East region of Nigeria: Borno, Yobe and Adamawa. Participants were identified through mapping of stakeholder involvement in Nigerian epidemic response. English-translated transcripts of each key informant interview and focus group discussion were then coded and key themes were elucidated and analysed. RESULTS: Major themes elucidated include developing inclusive coordination plans between civilian and military entities, facilitating human rights reporting mechanisms and distributing military resources more equitably across geographical catchment areas. The Nigerian Military served numerous functions: 37% (22/59) of respondents indicated 'security/peace' as the military's primary function, while 42% (25/59) cited health services. Variations across geographic settings were also noted: 35% (7/20) of participants in Borno stated the military primarily provided transportation, while 73% (11/15) in Adamawa and 29% (7/24) in Yobe listed health services. CONCLUSIONS: Robust civilian-military relations require an appropriately defined role of the military and clear civilian-military communication. Important considerations to contextualise civilian-military relations include military cultural-linguistic understanding, human rights promotion, and community-based needs assessments; such foci can facilitate the military's understanding of community norms and civilian cooperation with military aims. In turn, more robust civilian-military relations can promote overall epidemic response and reduce the global burden of disease.

The interface between humanitarianism, development and peacebuilding is increasingly congested. Western foreign policies have shifted towards pro-active stabilisation agendae and so Civil-Military Relationships (CMRel) will inevitably be more frequent. Debate is hampered by lack of a common language or clear, mutually understood operational contexts to define such relationships. Often it may be easier to simply assume that military co-operation attempts are solely to 'win hearts and minds', rather than attempt to navigate the morass of different acronyms. In healthcare, such relationships are common and more complex - partly as health is seen as both an easy entry point for diplomacy and so is a priority for militaries, and because health is so critical to apolitical humanitarian responses. This paper identifies the characteristics of commonly described kinds of CMRel, and then derives a typology that describe them in functional groups as they apply to healthcare-related contexts (although it is likely to be far more widely applicable). Three broad classifications are described, and then mapped against 6 axes; the underlying military and civilian motivations, the level of the engagement (strategic to tactical), the relative stability of the geographical area, and finally the alignment between the civilian and military interests. A visual representation shows where different types may co-exist, and where they are likely to be more problematic. The model predicts two key areas where friction is likely; tactical interactions in highly unstable areas and in lower threat areas where independent military activity may undermine ongoing civilian programmes. The former is well described, supporting the typology. The latter is not and represents an ideal area for future study. In short, we describe an in-depth typology mapping the Civil-Military space in humanitarian and development contexts with a focus on healthcare, defining operational spaces and the identifying of areas of synergy and friction.

In Ireland, traditionally, most public Adult Mental Health Services (AMHSs) had a small cohort of service users with eating disorders (EDs) in their service. However, over the last 5 years, the National Clinical Programmes have been encouraging Mental Health Services to develop ED programmes in each catchment area. This has culminated in a model of care for EDs for children and adults. It appears that in relation to AMHSs, meaningful inclusion of families/significant other(s) in ED programmes is somewhat inconsistent. This paper will discuss the possible impact of excluding or minimising family/significant other(s)' inclusion. It will also outline a suggested approach of including families/significant other(s) in a meaningful way in an out-patient ED programme.

The aim of this study was to investigate the modulation of an asthmatic response by titanium dioxide (TiO2) or gold (Au) nanoparticles (NPs) in a murine model of diisocyanate-induced asthma. On days 1 and 8, BALB/c mice received 0.3% toluene diisocyanate (TDI) or the vehicle acetone-olive oil (AOO) on the dorsum of both ears (20 µL). On day 14, the mice were oropharyngeally dosed with 40 µL of a NP suspension (0.4 mg·mL⻹ (â¼0.8 mg·kg⻹) TiO2 or Au). 1 day later (day 15), the mice received an oropharyngeal challenge with 0.01% TDI (20 µL). On day 16, airway hyperreactivity (AHR), bronchoalveolar lavage (BAL) cell and cytokine analysis, lung histology, and total serum immunoglobulin E were assessed. NP exposure in sensitised mice led to a two- (TiO2) or three-fold (Au) increase in AHR, and a three- (TiO2) or five-fold (Au) increase in BAL total cell counts, mainly comprising neutrophils and macrophages. The NPs taken up by BAL macrophages were identified by energy dispersive X-ray spectroscopy. Histological analysis revealed increased oedema, epithelial damage and inflammation. In conclusion, these results show that a low, intrapulmonary doses of TiO2 or Au NPs can aggravate pulmonary inflammation and AHR in a mouse model of diisocyanate-induced asthma.

In spite of recent advances in describing the health outcomes of exposure to nanoparticles (NPs), it still remains unclear how exactly NPs interact with their cellular targets. Size, surface, mass, geometry, and composition may all play a beneficial role as well as causing toxicity. Concerns of scientists, politicians and the public about potential health hazards associated with NPs need to be answered. With the variety of exposure routes available, there is potential for NPs to reach every organ in the body but we know little about the impact this might have. The main objective of the FP7 NanoTEST project ( www.nanotest-fp7.eu ) was a better understanding of mechanisms of interactions of NPs employed in nanomedicine with cells, tissues and organs and to address critical issues relating to toxicity testing especially with respect to alternatives to tests on animals. Here we describe an approach towards alternative testing strategies for hazard and risk assessment of nanomaterials, highlighting the adaptation of standard methods demanded by the special physicochemical features of nanomaterials and bioavailability studies. The work has assessed a broad range of toxicity tests, cell models and NP types and concentrations taking into account the inherent impact of NP properties and the effects of changes in experimental conditions using well-characterized NPs. The results of the studies have been used to generate recommendations for a suitable and robust testing strategy which can be applied to new medical NPs as they are developed.

There are inherent methodologic problems in investigating senile dementia of the Alzheimer type (SDAT) but this study indicated that, with regard to behavioral test measurement, some of the obvious problems are partially mitigated. First, these data showed that the progressive decline seen in longitudinal SDAT studies is of the same type and magnitude seen in cross-sectional comparisons. Thus, comparing SDAT groups differing in severity provides for the same observations as following up subjects with mild SDAT over time. This study also demonstrates that with certain kinds of tests, selective subject attrition may not be any greater in longitudinal investigations than found in normal aging research. Subjects who dropped out of the longitudinal study were not that different from those who remained in, at least in terms of initial test performance on challenging tests. In this study less than 5% of the subjects with SDAT originally classified as being in the mild stage of the disease remained in this stage after 6 3/4 years of investigation. This inexorable downward path of the subject with SDAT is what appears paramount. Given the similarity of staging in longitudinal and cross-sectional studies, prior test performance levels in the latter studies can be ascertained even if with less accuracy than in longitudinal studies.

Occlusion of the supraceliac abdominal aorta and hepatic vascular isolation were employed in a series of 15 patients as a definitive method to allow avascular hepatic resection. The series was compared with an earlier group of patients treated conventionally. In the avascular hepatic resection group there was no mortality; hypotension did not occur at the time of hepatic vascular isolation; rapid, accurate excision of the hepatic lesions could be achieved in a bloodless field; resection of midline lesions and those involving the great veins was possible; and "segmentectomies," or resections crossing segmental boundaries, could be performed where previously formal hepatic lobectomies were required. Concomitantly, the greatest amount of uninvolved hepatic parenchyma remained in situ. There was increased ease of operative management, reduced blood loss, and reduced operating time (mean, 2.8 hours).

We examined task persistence and postperformance attributions by Type As and Bs on tasks that varied in level of difficulty. On the basis of past research, we hypothesized that Type As would be more self-serving than Type Bs in their attributions for success and failure. We also hypothesized that task persistence would differ among Type As and Bs and would be dependent on task difficulty and perceived task diagnosticity. Type As and Bs attempted multiple sets of anagrams that were either easy or difficult. We measured persistence by the number of anagram sets attempted, and, after task performance, we assessed attributions for success and failure. Results supported both hypotheses. Type As took more credit for success than for failure, whereas Type Bs did not provide reliably different attributions for success and failure. Furthermore, Type As persisted longer at the task when it was difficult and when it was viewed as relatively low in information value. Type Bs persisted longer at the task when it was difficult but viewed as relatively high in information value. Results are discussed in the context of current debates regarding the responses of Type As and Bs to performance settings.

The self-appraisal model proposes that Type A behavior reflects active attempts to generate diagnostic information about abilities, particularly in situations that evoke high uncertainty. In Study 1, subjects were provided feedback indicating high or low uncertainty about underlying abilities in two domains. When subjects were more uncertain of their ability in one domain than in the other, Jenkins-Activity-Survey-defined Type As (but not Type Bs) subsequently constructed tests that were biased to assess the more uncertain domain. Study 2 examined postfailure performance. The model holds that Type As perform poorly because they suspend information gathering when faced with evidence that requisite abilities are absent. Results indicated that deficits emerged only if Type As believed that a second task assessed the same abilities as the initial task on which they failed. A final study examined social comparison among Type As and Bs. Results indicated that Type As engaged in social comparison to obtain diagnostic information, primarily when they were uncertain of their ability levels.

We examined the possibility that people hold multiple stereotypes of the elderly. Subjects were male and female university students. In the first phase of our study, stereotype content was sampled by asking subjects to describe the typical old person. In the second phase of the study, different subjects sorted traits from Phase 1 descriptions into one or more groups. Each group contained those traits that subjects felt could be found in one and the same older adult. Attitudes toward the stereotypes were also assessed. A distance matrix, based on the number of subjects who sorted each pair of traits into different groups, was analyzed by hierarchical cluster analysis. Evidence for multiple stereotypes was found both in the presence of contradictory traits given in Phase 1 descriptions and in the structure of the clusters. Different attitudes are identified for the cluster-defined stereotypes.

There is increasing evidence that diesel exhaust particles (DEP) could be incriminated in respiratory diseases. They have been shown to induce an inflammatory response in the lung and are suspected to be carcinogenic because of the presence of polyaromatic hydrocarbons (PAH) on their surface. DEP were tested on a human bronchial epithelial cell line (16HBE) in comparison with carbon black particles (CB) devoid of PAH. DEP and CB at 10mug/cm(2) induced the release of the lactate dehydrogenase (LDH) by 16HBE cells from 48hr of exposure. DEP at 5mug/cm(2) but not CB activated the binding of the nuclear factor kappaB (NF-kappaB) to DNA from 2hr of exposure up to 15hr. NF-kappaB is a transcription factor involved in the expression of some cytokines such as IL-8 and GM-CSF which have been shown to be released by 16HBE cells after DEP exposure. In addition, DEP as well as CB induced the expression of the c-fos proto-oncogene. Taken together, these new data suggest that the activation of NF-kappaB and the expression of c-fos could contribute to the proliferation and chronic inflammation processes induced in lungs after DEP exposure.
RESUMO
Standard reference diesel exhaust particles (DEP) SRM 1650 are often used to evaluate the toxicity of DEP. However, these particles did not necessarily reflect the effects of DEP representative of present diesel automobiles. This study was designed to compare the effects of SRM 1650 to DEP from representative cars (RC-DEP) on airway epithelial cells. Therefore we established a method to recover RC-DEP impacted on filters after emission from diesel automobiles on test beds. Electron microscopy and flow cytometry showed that these two types of particles were phagocytosed to the same extent by epithelial cells. This phagocytosis is not dependent on the adsorbed organic compounds in contrast to the cytotoxic effect evaluated by measurements of LDH release. This is emphasized by the fact that RC-DEP equipped with an oxidation catalyst are less cytotoxic than particles from a non-equipped vehicle or SRM 1650. This type of catalyst also reduces significantly the release of GM-CSF by bronchial epithelial cells. We have shown in the present paper that SRM 1650 may be used as a surrogate of DEP. However, exhaust gas post-treatment devices of current diesel automobiles reduce the cytotoxicity as well as the inflammatory response of these particles.

A wound bed may be prepared by various non-surgical debridements using autolytic, biological or enzymatic techniques. These are all effective in selective wounds but tend to be time consuming. Surgical debridement is not selective since healthy collateral tissue is also removed. Physical debridement uses whirlpool therapy to slough off necrotic tissues - the saline which comes out of the hand piece if vapourized over the wound - and therefore disseminates contaminated droplets. Hydrosurgery combines physical and surgical debridement but does not have their drawbacks. Water dissection works by using a high-pressure jet of sterile saline that travels parallel to the wound and creates a Venturi effect, thus enabling the selective removal of necrotic tissues without dissemination of contaminants. In this study, the authors report on 167 sub-acute and chronic wounds from 155 patients treated under general anaesthesia by hydrosurgery (Versajet). Of these, 95% of the debrided wounds were immediately covered with an autologous meshed graft. Compared to other debridement techniques, hydrosurgery has two main advantages: namely its tissue selectivity and its high percentage of successful engraftment after immediate skin grafting.

Diesel exhaust particles (DEP) are suspected to be involved in the aggravation of inflammatory respiratory diseases. We have shown previously, in human bronchial epithelial cell line 16HBE 14o-, that DEP induced the release of the proinflammatory cytokines granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-8 (IL-8) after 24 h of exposure. Gene expression of these cytokines is regulated by transcription factors including NF-κB and AP-1, which are known to be sensitive to oxidative stress. Their activation by DEP was investigated in comparison with a pure oxidant, H2O2 A 4-h exposure to DEP (10 µg/cm(2)) or to H2O2 (100 µM) increased NF-κB DNA binding in 16HBE cells as assessed by electrophoretic mobility shift assay. AP-1 was only activated by H202 in the same conditions. Organic extracts of DEP increased NF-κB DNA binding as did native DEP, suggesting the role of the polycyclic aromatic hydrocarbons (PAH) in this NF-κB increased DNA binding. Dimethylthiourea (DMTU), an antioxidant, inhibited the NF-κB DNA binding induced by DEP, suggesting an involvement of reactive oxygen species (ROS) in the transduction pathways leading to NF-κB activation. Moreover, the MEK pathway inhibitor PD98059 inhibited DEP-induced NF-κB DNA binding. The role of Erk 1/2 was likely implicated, since DEP induced an increase of Erk phosphorylation.
RESUMO
The fate of gallstones spilled during laparoscopic cholecystostomy has been thought to be relatively benign. Recent experience and a review of the recent literature shows that this is not always the case. We report three cases of complications of retained stones and analyse the literature with regard to types of complications, time to presentation, and recommendations for managing spilled gallstones. Retained gallstones have been shown to cause adhesions in the rat and inflammatory reactions in dogs with no evidence of absorption. The average time to presentation of complications arising from retained gallstones is 27.3 weeks. Complications include: Intraabdominal abscess formation with or without abdominal wall sinus tract formation, persisting abdominal wall sinus tracts from port site abscess, subhepatic inflammatory masses, cholelithoptysis, microabscesses and granuloma formation, liver abscess and "dumbell" shaped abscess with one side of the "dumbell" forming a subcutaneous abscess. We recommend the judicious use of retrieval devices during the extraction phase of the laparoscopic cholecystectomy, diligent removal of any spilled stones and awareness of delayed postoperative pain and tenderness as a harbinger of symptomatic retained gallstones. Documentation of intraoperative gallstone spillage, volume, type of gallstones, and effort to retrieve is recommended.
