Incidence of Deep Vein Thrombosis in Hospitalized Chinese Medical Patients and the Impact of DVT Prophylaxis

Objective. To evaluate the incidence of deep vein thrombosis in hospitalized Chinese medical patients and the impact of DVT prophylaxis. Methods. All cases of confirmed proximal DVT from 1 January 2005 to 31 December 2008 were reviewed retrospectively to determine the presence of risk factors and whether DVT developed: during hospitalization in medical wards or in case of readmission with a diagnosis of DVT within 14 days of discharge from a recent admission to medical wards. The impact of prophylaxis will be estimated by comparing the annual incidence of proximal DVT among medical patients hospitalized from 2005 to 2007 with that of 2008 (DVT prophylaxis commonly used). Results. From 1 January 2005 to 31 December 2008, 3938 Doppler ultrasound studies were performed for suspected DVT. Proximal DVT was diagnosed in 687 patients. The calculated incidence of proximal DVT among medical patients hospitalized for at least two days was 1.8%, 2%, and 1.7% for the year 2005, 2006, and 2007, respectively. The incidence was 1.1% for 2008 (P < .001). Conclusion. Proximal DVT was substantial in Chinese medical patients, and DVT prophylaxis might reduce such risk

Efeitos do tratamento com captopril e losartan em ratos Wistar e ratos espontaneamente hipertensos submetidos a hipertensão arterial pulmonar com monocrotalina

A hipertensão arterial pulmonar (HAP) é uma doença que se inicia com o aumento da resistência das arteríolas pulmonares. Após a sua instalação, sucedem-se várias alterações sobre os sistemas cardiovascular, respiratório e autonômico. Apesar dos trabalhos disponíveis na literatura, o desenvolvimento desta doença em modelos experimentais de hipertensão arterial sistêmica permanece ainda por ser estudado, bem como os efeitos terapêuticos de bloqueadores do sistema renina-angiotensina na reversão desta doença. Os objetivos deste estudo foram avaliar os efeitos cardiovasculares, autonômicos e respiratórios promovidos pela HAP induzida pela monocrotalina (MCT) em ratos Wistar e SHR e os efeitos terapêuticos do tratamento crônico com captopril e losartan na reversão da HAP. Para tanto, foram utilizados ratos Wistar (150-180g) e SHR (150-180g), divididos nos seguintes grupos: Wistar controle tratado com salina ou MCT (WIS-CON-SAL e WIS-CON-MCT, respectivamente), SHR controle tratado com salina ou MCT (SHR-CON-SAL e SHR-CON-MCT, respectivamente), Wistar tratados com Captopril + salina ou MCT (WIS-CPT-SAL e WIS-CPT-MCT, respectivamente), SHR tratados com Captopril + salina ou MCT (SHR-CPT-SAL e SHR-MCT-CPT, respectivamente), Wistar tratados com Losartan + salina ou MCT (WIS-LOS-SAL e WIS-LOS-MCT, respectivamente), SHR tratados com Losartan + salina ou MCT (SHR-LOS-SAL e SHR-LOS-MCT, respectivamente). Os animais tratados com MCT receberam uma única injeção subcutânea (60 mg/Kg SC) e os controles receberam o mesmo volume de salina (~0,8 mL). Ao término da 3ª senama, quando os animais MCTs controle apresentaram HAP, foi feito o tratamento com captopril (100 mg/Kg/mL) ou losartan (30 mg/Kg/mL) na água de beber por 2 semanas no volume diário de 30 mL. Após o tratamento com captopril ou losartan, foram realizados os registros cardiovasculares, respiratórios, gasométricos e a histologia pulmonar. Os resultados mostraram um significativo aumento do Índice Pulmonar nos animais controles tratados com MCT (Wistar e SHR) quando comparados com seus respectivos controles. As pressões ventriculares (PSmáx, PDI e PDF) também foram significativamente aumentadas nos grupos MCTs, bem como os valores de pressão arterial sistólica and diastólica, frequência cardíaca, pressão de pulso e labilidade da pressão arterial média. O tratamento com captopril normalizou todos os parâmetros estudados, no entanto, o losartan se mostrou ineficiente em normalizar os parâmetros hemodinâmicos. As análises morfométricas mostraram um espessamento da camada média dos dos ramos distais da artéria pulmonar e uma diminuição do lúmen nos grupos tratados com MCT. O tratamento com captopril e losartan normalizou estes parâmetros, embora o grupo tratado com losartan tenha sido menos eficaz que o captopril, pois os tratamentos mostraram diferenças significativas entre si. Quanto a avaliação autonômica, os animais MCT mostraram aumento do tônus simpático cardíaco e redução do tônus parassimpático cardíaco. Novamente, o tratamento com captopril normalizou estes parâmetros, enquanto que o losartan foi ineficaz em normalizá-los. Quanto aos parâmetros respiratórios, observamos aumentos no volume corrente, na frequência respiratória, na ventilação minuto e na ventilação alveolar dos animais controles tratados com MCT. Apenas o tratamento com captopril normalizou estes parâmetros. A avaliação gasométrica mostrou que os grupos controles tratados com MCT apresentaram redução da pressão parcial de O2 (hipóxia), aumento da pressão parcial de CO2 (hipercapnia), queda da porcentagem de saturação da hemoglobina (% Hb), aumento do bicarbonato (HCO3-) e acidose. O tratamento com captopril normalizou todos os parâmetros gasométricos, enquanto que o mesmo não foi observado com o losartan para os animais SHR submetidos a HAP. Nossos resultados mostraram que a MCT induziu ao quadro de HAP nos animais Wistar e SHR, bem como importantes alterações cardiovasculares, autonômicas, respiratórias, gasométricas e morfológicas pulmonares. Os tratamentos com captopril e losartan foram capazes de reverter a HAP em animais Wistar e SHR, porém, o captopril se mostrou mais eficiente em normalizar esses parâmetros quando comparados ao losartan. Estes resultados sugerem que o uso de bloqueadores do sistema renina angiotensina pode ser uma opção terapêutica para o tratamento da HAP.

Towards a global partnership model in interprofessional education for cross-sector problem-solving

Objectives A partnership model in interprofessional education (IPE) is important in promoting a sense of global citizenship while preparing students for cross-sector problem-solving. However, the literature remains scant in providing useful guidance for the development of an IPE programme co-implemented by external partners. In this pioneering study, we describe the processes of forging global partnerships in co-implementing IPE and evaluate the programme in light of the preliminary data available. Methods This study is generally quantitative. We collected data from a total of 747 health and social care students from four higher education institutions. We utilized a descriptive narrative format and a quantitative design to present our experiences of running IPE with external partners and performed independent t-tests and analysis of variance to examine pretest and posttest mean differences in students’ data. Results We identified factors in establishing a cross-institutional IPE programme. These factors include complementarity of expertise, mutual benefits, internet connectivity, interactivity of design, and time difference. We found significant pretest–posttest differences in students’ readiness for interprofessional learning (teamwork and collaboration, positive professional identity, roles, and responsibilities). We also found a significant decrease in students’ social interaction anxiety after the IPE simulation. Conclusions The narrative of our experiences described in this manuscript could be considered by higher education institutions seeking to forge meaningful external partnerships in their effort to establish interprofessional global health education

Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.

BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

Using simulation learning through academic-practice partnership to promote transition to clinical practice: a qualitative evaluation

AimTo explore the effect of an innovative simulation education programme on nursing students' transition-to-practice experiences.BackgroundAcademic-practice partnership is emerging as an important vehicle for improving nursing students' transition-to-practice. Using existing university resources, academic educators and alumni developed an innovative simulation educational programme known as the Simulated Professional Learning Environment (SIMPLE) to align the educational process with the realities of nursing practice. Educators and alumni collaborated to create and facilitate 15hours of simulation sessions that comprised the learning platform for the SIMPLE programme.DesignThis was a descriptive qualitative study.MethodFocus groups were conducted in 2012 with 22 final-year nursing students completing their transition-to-practice clinical practicum. The interview transcripts were analysed using content analysis.ResultsThree themes were identified from the analysis: experiencing the role of staff nurse'; knowing how to'; and learning from the seniors'. Experiencing the role of staff nurse in the programme showed the nursing students what to expect and how to prepare for their roles. Knowing how to focus on holistic patient care, manage difficult' clients and communicate with other healthcare professionals were the learning outcomes gained from the programme. Learning from the seniors' about hospital work processes positively influenced the nurses' transition-to-practice experiences.ConclusionThis study provides support for introducing the simulation education programme as an enhancement during nursing students' final year to improve their transition-to-practice experiences. A stronger collaborative relationship between academic educators and practising nurses could be further fostered by expanding this learning platform
