RESUMO

Non-physician clinicians (NPCs) in low and middle-income countries (LMICs) often have little physical proximity to the resources-equipment, supplies or skills-needed to deliver effective care, forcing them to refer patients to distant sites. Unlike equipment or supplies, which require dedicated supply chains, physician/specialist skills needed to support NPCs can be sourced and delivered through telecommunication technologies. In LMICs however, these skills are scarce and sparsely distributed, making it difficult to implement commonly used real-time (synchronous), hub-and-spoke telemedicine paradigms. An asynchronous teleconsultations service was implemented in Turkana County, Kenya, connecting NPCs with a volunteer network of remote physicians and specialists. In 2017-18, the service supported over 100 teleconsultations and referrals across 20 primary healthcare clinics and two hospitals. This qualitative study aimed to explore the impact of the telemedicine intervention on health system stakeholders, and perceived health-related benefits to patients. Data were collected using Appreciative Inquiry, a strengths-based, positive approach to assessing interventions and informing systems change. We highlight the impact of provider-to-provider asynchronous teleconsultations on multiple stakeholders and healthcare processes. Provider benefits include improved communication and team work, increased confidence and capacity to deliver services in remote sites, and professional satisfaction for both NPCs and remote physicians. Health system benefits include efficiency improvements through improved care coordination and avoiding unnecessary referrals, and increased equity and access to physician/specialist care by reducing geographical, financial and social barriers. Providers and health system managers recognised several non-health benefits to patients including increased trust and care seeking from NPCs, and social benefits of avoiding unnecessary referrals (reduced social disruption, displacement and costs). The findings reveal the wider impact that modern teleconsultation services enabled by mobile technologies and algorithms can have on LMIC communities and health systems. The study highlights the importance of viewing provider-to-provider teleconsultations as complex health service delivery interventions with multiple pathways and processes that can ultimately improve health outcomes.

RESUMO

Nurses and midwives of Australia now is the time for change! As powerfully placed, Indigenous and non-Indigenous nursing and midwifery professionals, together we can ensure an effective and robust Indigenous curriculum in our nursing and midwifery schools of education. Today, Australia finds itself in a shifting tide of social change, where the voices for better and safer health care ring out loud. Voices for justice, equity and equality reverberate across our cities, our streets, homes, and institutions of learning. It is a call for new songlines of reform. The need to embed meaningful Indigenous health curricula is stronger now than it ever was for Australian nursing and midwifery. It is essential that nursing and midwifery leadership continue to build an authentic collaborative environment for Indigenous curriculum development. Bipartisan alliance is imperative for all academic staff to be confident in their teaching and learning experiences with Indigenous health syllabus. This paper is a call out. Now is the time for Indigenous and non-Indigenous nurses and midwives to make a stand together, for justice and equity in our teaching, learning, and practice. Together we will dismantle systems, policy, and practices in health that oppress. The Black Lives Matter movement provides us with a 'now window' of accepted dialogue to build a better, culturally safe Australian nursing and midwifery workforce, ensuring that Black Lives Matter in all aspects of health care.

RESUMO

As osteoporosis relies largely on self-managed prevention and adherence to long-term treatment regimens, it is imperative that those at risk understand the disease that they are attempting to prevent. Ambiguity regarding osteoporosis and reluctance to take anti-osteoporosis medication (AOM) as well as calcium was noted in Australian post-menopausal women. This may lead to underestimating women's own risk of osteoporosis and fracture. INTRODUCTION: Fragility fractures caused by osteoporosis have been known to inflict significant personal and financial burden on individuals and society. As treatment of osteoporosis relies largely on self-managed prevention and adherence to long-term AOM regimens, it is imperative that women have a sound understanding of the disease that they are attempting to prevent. Much can also be gained from qualitatively exploring the level of osteoporosis knowledge particularly in post-menopausal women who are at greater risk of osteoporosis and fractures. This study thus aims to determine what post-menopausal Australian women know about osteoporosis and osteoporosis prevention. METHOD: Six focus group sessions, using purposive sampling, were conducted with 23 female participants (mean age 68 years (range 62-83)). Women responded to a series of open-ended questions regarding their knowledge about osteoporosis. The audiotaped focus groups were transcribed verbatim and analysed using a thematic analysis framework. RESULTS: Three key themes were identified: ambiguity about the nature of osteoporosis, ambiguity about osteoporosis prevention and reluctance to take AOM and calcium. CONCLUSION: Ambiguity associated with risk and prevention may provide women with a false sense of security that they are adequately acting to prevent the disease. Underestimation of their risk of osteoporosis and fracture as well as reluctance associated with AOM may be barriers to osteoporotic fracture prevention.

RESUMO

Gender-based violence (GBV) in humanitarian emergencies is progressively recognized as a global public health problem. Detrimental gender norms influence male perpetrated GBV against women, and social and structural contexts of forced migration and camp resettlement contribute to problematic gender norm development. The review sought to elucidate the dynamics that link gender socialization among male youth in sub-Saharan Africa with violent sexual behaviors. Two concepts were explored: (1) male gender socialization in sub-Saharan Africa related to GBV perpetration patterns and (2) the effect of forced migration on male socialization and GBV. We reviewed articles using a standard systematic review methodology, searching academic databases for peer-reviewed articles, and contacting experts for gray literature. Our initial search identified 210 articles. We manually reviewed these, and 19 met the review inclusion criteria. We identified 20 variables from the first concept and 18 variables from the second. GBV perpetration by male youth is positively associated with social pressures as well as cultural and religious beliefs. Amid forced migration, personal, societal, and cultural preexisting gender inequalities are often amplified to encourage GBV perpetration. The literature revealed aspects of culture, language, role modeling, religion, and the context of violence as important factors that shape young men's perspectives regarding the opposite sex and gender relations as well as sexual desires and dominance. Overall, though, literature focusing on male socialization and GBV prevention is limited. We made recommendations for future studies among refugee male youth in order to better understand these relationships.

RESUMO

The objective of our study was to characterize the diagnostic performance of cytology for assessing hepatic lipid content (HLC) in dairy cows by comparing microscopic evaluation of lipid vacuolation in touch imprint slide preparations of liver biopsies with quantitative measurement of triglyceride concentration ([TG]; mg/mg of wet weight) in paired biopsy samples. Our study also sought to compare the diagnostic performance of liver cytology, plasma nonesterified fatty acid concentration ([NEFA]), and plasma ß-hydroxybutyrate concentration ([BHB]) derived from a measurement performed on whole blood, for assessing HLC. Chemical extraction of TG from liver tissue remains the gold standard for quantifying HLC, largely because available blood tests, although useful for detecting some types of pathology, such as increased lipid mobilization, ketosis, or hepatocellular injury, are nonspecific as to etiology. Veterinary practitioners can sample bovine liver for cytological evaluation in a fast, minimally invasive, and inexpensive manner. Thus, if highly predictive of HLC, cytology would be a practical diagnostic tool for dairy veterinarians. In our study, liver biopsy samples from Holstein cows (219 samples from 105 cows: 52 from cows 2 to 20 d prepartum, 105 from cows 0 to 10 d in milk, 62 from cows 18 to 25 d in milk) were used to prepare cytology slides and to quantify [TG] using the Folch extraction method followed by the Hantzch condensation reaction and spectrophotometric measurement. An ordinal scale (0-4) based on amount of hepatocellular cytoplasm occupied by discrete clear vacuoles was used by 3 blinded, independent observers to rank HLC in Wright-Giemsa-stained slides. Interobserver agreement in cytology scoring was good. Corresponding plasma [NEFA] and [BHB] measurements were available for 187 and 195 of the 219 samples, respectively. Liver [TG] correlated more strongly with cytology score than with NEFA or BHB, and receiver operating characteristic curve analysis showed that cytology had better diagnostic performance than either NEFA or BHB for correctly categorizing [TG] at thresholds of 5, 10, and 15%. Hepatic lipidosis in high-producing dairy cows is of major clinical and economic importance, and this study demonstrates that cytology is an accurate means of assessing HLC. Additional work is indicated to evaluate the diagnostic utility of liver cytology.

RESUMO

Self-assembly of a tetrapeptide covalently attached to a thiophene-based monomer produced a gel with a fibrous, porous structure. Conditions were identified in which the thiophene end groups could undergo polymerization while retaining the 3D structure, resulting in the formation of nanofibrous gels with conductivities averaging 10-4 S cm-1.

RESUMO

The components of many signaling pathways have been identified and there is now a need to conduct quantitative data-rich temporal experiments for systems biology and modeling approaches to better understand pathway dynamics and regulation. Here we present a modified Western blotting method that allows the rapid and reproducible quantification and analysis of hundreds of data points per day on proteins and their phosphorylation state at individual sites. The approach is of particular use where samples show a high degree of sample-to-sample variability such as primary cells from multiple donors. We present a case study on the analysis of >800 phosphorylation data points from three phosphorylation sites in three signaling proteins over multiple time points from platelets isolated from ten donors, demonstrating the technique's potential to determine kinetic and regulatory information from limited cell numbers and to investigate signaling variation within a population. We envisage the approach being of use in the analysis of many cellular processes such as signaling pathway dynamics to identify regulatory feedback loops and the investigation of potential drug/inhibitor responses, using primary cells and tissues, to generate information about how a cell's physiological state changes over time.

RESUMO

In veterinary medicine, anemia without an appropriate compensatory hematopoietic response is termed nonregenerative. Nonregenerative anemia is a common clinical entity, occurring as a result of diminished or ineffective erythropoiesis in association with many types of pathology. This article reviews nonregenerative anemia in domestic animals, emphasizing mechanisms of disease, and also covers other conditions associated with nonregenerative anemia in people. Many aspects of nonregenerative anemia in animals are worthy of further investigation, from molecular mechanisms of disease to epidemiologic impacts.

RESUMO

Janus kinase (JAK) enzymes are involved in cell signaling pathways activated by various cytokines dysregulated in allergy. The objective of this study was to determine whether the novel JAK inhibitor oclacitinib could reduce the activity of cytokines implicated in canine allergic skin disease. Using isolated enzyme systems and in vitro human or canine cell models, potency and selectivity of oclacitinib was determined against JAK family members and cytokines that trigger JAK activation in cells. Oclacitinib inhibited JAK family members by 50% at concentrations (IC50 's) ranging from 10 to 99 nm and did not inhibit a panel of 38 non-JAK kinases (IC50 's > 1000 nM). Oclacitinib was most potent at inhibiting JAK1 (IC50 = 10 nM). Oclacitinib also inhibited the function of JAK1-dependent cytokines involved in allergy and inflammation (IL-2, IL-4, IL-6, and IL-13) as well as pruritus (IL-31) at IC50 's ranging from 36 to 249 nM. Oclacitinib had minimal effects on cytokines that did not activate the JAK1 enzyme in cells (erythropoietin, granulocyte/macrophage colony-stimulating factor, IL-12, IL-23; IC50 's > 1000 nM). These results demonstrate that oclacitinib is a targeted therapy that selectively inhibits JAK1-dependent cytokines involved in allergy, inflammation, and pruritus and suggests these are the mechanisms by which oclacitinib effectively controls clinical signs associated with allergic skin disease in dogs.

RESUMO

Effects of low-dose LPS (0.1 µg/kg i.v.) on leukocyte and platelet parameters measured using an Advia 120 hematology analyzer were investigated. Five dogs received a saline sham treatment prior to LPS, and blood was collected before and 3, 6, and 24 h post-treatment. LPS-treated dogs had mild neutrophil toxic change and increased neutrophil bands at 3 and 6 h. Compared to saline-treated controls, total leukocyte, neutrophil, and monocyte counts of LPS-treated dogs were significantly decreased at 3 h and increased at 24 h. Compared to baseline, total leukocyte counts of LPS-treated dogs were significantly decreased at 3 h and increased at 24 h. Mean platelet volume was significantly increased and mean platelet component concentration was decreased at 3 h compared to baseline. Platelet count was significantly decreased at 3 and 6 h; plateletcrit did not change significantly. High dosage is not required in order to detect LPS-mediated hematologic effects in dogs. Low-dose LPS administration causes significant changes in leukocyte and platelet indices in dogs without causing severe clinical signs or death.

RESUMO

The accuracy of 4 commercial enzyme-linked immunosorbent assays (ELISAs) for diagnosis of bovine paratuberculosis was compared using sera from 53 Mycobacterium avium subsp. paratuberculosis (MAP) fecal culture-positive dairy cows (cases) and sera from 345 dairy cattle resident in 11 fecal culture-negative herds on 2 consecutive occasions 1 year apart (controls). The specificity of all 4 ELISA kits was >99%, and their diagnostic sensitivity ranged from 30.2% to 41.5%. Pairwise comparison of ELISAs found no significant differences (McNemar's chi-square test > 0.05), and assay agreement for categorical assay interpretation (positive or negative) was high (>98%) with kappa values ranging from 0.84 to 0.95. Receiver operating characteristic (ROC) curve analysis and the corresponding area under the ROC curves indicate that kit B had the highest overall accuracy. Thus, all 4 ELISA kits for bovine paratuberculosis had comparable accuracy when tested on Chilean dairy cattle, with kit B having a slight statistical advantage based on ROC area under the curve analysis. This suggests that any of the 4 kits could be appropriate for herd certification and for paratuberculosis control programs on Chilean dairy cattle.

RESUMO

REASONS FOR PERFORMING STUDY: Endotoxaemia is one of the most severe and ubiquitous disease processes in horses. Although dimethyl sulphoxide (DMSO) is used clinically in horses, there is no study indicating its efficacy in endotoxaemic horses. HYPOTHESIS: DMSO ameliorates the clinical response to i.v. lipopolysaccharide (LPS) administration. METHODS: Eighteen horses were assigned randomly to one of 4 groups: Normosol-LPS (0.2 mug/kg bwt, i.v.); DMSO (1 g/kg bwt, i.v.)-saline; high-dose DMSO (1 g/kg bwt, i.v.)LPS; low-dose DMSO (20 mg/kg bwt, i.v.)-LPS. Horses participating in the DMSO-saline group were later assigned randomly to one of the LPS groups. Data for physical parameters, white blood cell counts, plasma TNF-alpha, and blood lactate and glucose concentrations were examined for the effect of treatment using a repeated-measures mixed-model ANOVA. A value of P<0.05 was considered significant. RESULTS: Endotoxaemia occurred in all horses receiving LPS, as indicated by the clinical score, physical parameters, haemoconcentration and leucopenia. High-dose DMSO ameliorated the effect of LPS on fever. DMSO, at either dose, but did not have a significant effect on LPS-induced changes in all other evaluated parameters. CONCLUSIONS: In this study, DMSO had minimal effects on clinical signs of induced endotoxaemia in horses. The effects were manifested by amelioration of LPS-induced fever.

RESUMO

BACKGROUND: It is not known whether the choice of topical anaesthetic influences the likelihood of successful i.v. cannulation in the paediatric population. The null hypothesis of this study was that no difference exists in the initial success rate of cannulation between two commonly used topical anaesthetics. METHODS: A randomized double-blind trial conducted on patients between the age of 12 months and 12 yr presenting to a tertiary hospital emergency department. Patients requiring cannulation were randomized to either 4% amethocaine gel (AnGEL) or 5% lidocaine and prilocaine in a 1:1 emulsion (EMLA). The primary endpoint was success of initial attempt at i.v. cannulation. RESULTS: One hundred and seventy-seven patients were analysed of 203 enrolled. The success rate of AnGEL (73/97, 75%) and EMLA (59/80, 74%) did not significantly differ (chi2(1) 0.05, P=0.82). CONCLUSIONS: No difference exists in the cannulation success rates between the two anaesthetics. The choice of topical anaesthetic in paediatric cannulation should be based on other factors such as cost, time to anaesthesia, efficacy of the agent, and adverse effect profile.

RESUMO

Thirteen dogs with previously untreated multicentric lymphoma were enrolled in a prospective study investigating the effects of low-dose rate total body irradiation (TBI) and chemotherapy. Dogs received either 6 or 8 Gy TBI in half-body fractions, 2 weeks apart. Toxicity consisted of mild to moderate haematological and gastrointestinal (GI) signs. One dog died from treatment complications. Anorexia was noted independent of dose. Haematological toxicity was more common and more severe after 8 Gy treatment. GI toxicity was more likely postcaudal half-body irradiation with 8 Gy. Other than leukotrichia, late effects from radiation were not observed. Results indicated that haematological and nonhaematological toxicity was dose dependent. However, the protocol was well tolerated and treatment intensification using a 2-week inter-radiation interval was possible in all dogs treated with 6 Gy. Preliminary survival data for these dogs were very encouraging, providing a strong rationale to analyse the efficacy of low-dose rate irradiation (LDRI) in canine lymphoma.

RESUMO

BACKGROUND: Kidney cancers account for almost 2% of all cancers worldwide, with 150,000 new cases and 78,000 deaths from the disease occurring annually. An increase in the incidence of kidney neoplasm in western countries was noticed in the past few years. Between 1988 and 1992, the incidence of renal cancer per 100,000 person-year among males in USA, Norway, and France was 34.1, 9.00, and 16.10, respectively. Among females in the same countries, it was 5.70, 5.00, and 7.30, respectively. Although several individual case-control studies examined the association of meat intake and renal cancer risk, the results were inconsistent because of the insufficient statistical power of the individual studies. Therefore, the following meta-analysis was designed to help in clarifying the association. METHODS: Electronic search of MEDLINE, OVID, and PUBMED databases which have articles published between (1966 and 2006) was conducted to select studies for this meta-analysis. STATISTICAL ANALYSIS: Fixed and random-effects meta-analytical techniques were used to estimate the overall association between meat consumption and kidney cancer. RESULTS: Thirteen case-control studies were found. This meta-analysis supported a positive relationship between meat consumption and risk of renal cancer. Summary results indicated that there was from 20% to 22% higher risk of renal cancer among those in the highest relative to the lowest category of poultry and processed meat consumption. Consumption of all meat and red meat was associated with 27% and 30% higher risk, respectively. The increased risks were statistically significant. CONCLUSIONS: Increased consumption of all meat, red meat, poultry, and processed meat is associated with an increase risk of kidney cancer. Reduction of meat consumption is an important approach to decreasing the incidence of kidney cancer in the general population.

RESUMO

A peripheral primitive neuroectodermal tumor (pPNET), most consistent with a human Ewing's sarcoma, is described in a 5-month-old male Australian Shepherd puppy. The first tumor site detected was in the left frontal bone of the skull with apparent subsequent rapid metastases to multiple sites in the axial and appendicular skeleton and bone marrow, kidneys, and perihyphophyseal meninges. Radiographically, all bone lesions were lytic and there was also a humeral bone fracture. Histologically, the tumor was diagnosed as a small round blue cell tumor. At this stage, the differential diagnosis included a lymphoma, rhabdomyosarcoma, and a PNET of the peripheral nervous system. However, the cells had positive expression of triple neurofilament antigens as detected immunocytochemically. The cells were negative for a broad panel of canine-specific leucocyte cell marker antigens for desmin, smooth muscle actin, synaptophysin, and CD99. Ultrastructurally, the cells contained occasional dense core neurosecretory granules and intermediate filaments with intercellular desmosomal-like junctions and abundant glycogen clusters. Based on the age of the dog, the clinical history, the distribution of gross lesions, histologic characteristics of a small round blue cell tumor, and immunocytochemical and ultrastructural evidence of neuroectodermal differentiation, a diagnosis of a pPNET similar to a human Ewing's sarcoma was made.

RESUMO

We describe a case of a dog with hepatosplenic lymphoma, a disease characterized by infiltration of the liver, spleen, and bone marrow with gammadelta T cells, absence of peripheral lymphadenopathy, and an aggressive clinical course. Physical examination findings, hematologic and biochemical abnormalities, and clinical course of the disease in this patient were similar to those in humans. Immunophenotyping of liver and spleen aspirates supported an antemortem diagnosis of T-cell lymphoma consistent with hepatosplenic lymphoma. The diagnosis was confirmed postmortem by a combination of routine histopathology, showing a consistent pattern of organ involvement, and immunohistochemistry showing the infiltrating neoplastic lymphocytes to be T cells expressing the gammadelta T-cell receptor. To our knowledge, this is the first reported case of hepatosplenic lymphoma in a dog.

RESUMO

A remote medical monitoring system is described, which continuously monitors patients' state of health. The system uses the services provided by intranets and the Internet to allow remote supervision of patients, who may be domiciled in their own home. A hardware/software prototype system has been constructed to demonstrate the use of non-invasive and minimally intrusive sensors attached to patients. Continuous real-time data is acquired, stored and processed. A wireless system or wires connect these monitor devices to the World Wide Web and, on request, information is delivered to authorized medical staff via a web browser or Wireless Application Protocol-enabled mobile telephones. Medical staff may examine real-time data or graphical information and make comparisons with historical data. Parameters may be set to select and control the data acquisition devices.
