We compared the diagnostic accuracy of emergency medicine residents (EMRs) and radiology residents (RRs) in performing focused abdominal sonography for trauma (FAST). The cohort in this prospective study comprised 200 unstable patients (163 males and 37 females; mean ± standard deviation of age, 34.3 ± 16.4 y) who presented with trauma. These patients were evaluated using FAST, first by EMRs and subsequently by RRs. Patients with positive FAST results underwent further diagnostic procedures such as computed tomography, diagnostic peritoneal lavage and laparotomy. Those with negative FAST results underwent clinical follow-up for 72 h until their condition deteriorated or they were discharged. Sensitivity, specificity, positive and negative predictive values and accuracy in evaluating free intraperitoneal fluid were 80%, 95%, 57%, 98% and 94% when FAST was performed by EMRs and 86%, 95%, 59%, 98% and 94% when FAST was performed by RRs. The level of agreement between EMRs and RRs was moderate (κ = 0.525). FAST is a useful screening tool for initial assessment of free abdominal fluid in patients with trauma. Our results indicate that EMRs can perform sonography on trauma patients as successfully as RRs.  相似文献

Background

Inappropriate diagnosis and treatment of pain, agitation, and delirium (PAD) in intensive care settings results in poor patient outcomes. We designed and used a protocol for systematic assessment and management of PAD by the nurses to improve clinical intensive care unit (ICU) outcomes.

Materials and Methods

A total of 201 patients admitted to 2 mixed medical-surgical ICUs were randomly allocated to protocol and control groups. A multidisciplinary team approved the protocol. Pain was assessed by Numerical Rating Scale and Behavioural Pain Scale, agitation by Richmond Agitation Sedation Scale, and delirium by Confusion Assessment Method in ICU. The Persian version of the scales was prepared and tested for validity, reliability, and feasibility in a preliminary study. The patients in the protocol group were managed pharmacologically according to the protocol, whereas those in the control group were managed according to the ICU routine.

Results

The median (interquartile range) for the duration of mechanical ventilation in the protocol and control groups was 19 (9.3-67.8) and 40 (0-217) hours, respectively (P = .038). The median (interquartile range) length of ICU stay was 97 (54.5-189) hours in the protocol group vs 170 (80-408) hours in the control group (P < .001). The mortality rate in the protocol group was significantly reduced from 23.8% to 12.5% (P = .046).

Conclusion

The current randomized trial provided evidence for a substantial reduction in the duration of need to ventilatory support, length of ICU stay, and mortality rates in ICU-admitted patients through protocol-directed management of PAD.  相似文献

Background:Previous studies have shown that spiritual experience may reduce cardiovascular disease (CVDs). However, little is known about the relationship between spiritual health and the gender-specific risk of CVDs in communities with different cultures.Methods:A total of 3249 individuals (53.7% female, 75.0% middle-aged) participated in the Tehran Lipid and Glucose Study (TLGS) from 2015 to 2017 were included. Based on the ACC/AHA pooled cohort equation, CVD risk over ten years was examined. Spiritual health was measured using a developed tool for measuring spiritual health in Muslim populations (SHIMA-48). Linear regression models were used to assess the association between spiritual health and ACC/AHA risk scores. The natural logarithm scale was calculated to consider the normal distribution hypothesis of the regression model.Results:The current results suggest a slight but significant increase in the mean of spiritual health in women compared to men in both cognitive/emotional and behavioral dimensions (P < 0.001). In both sexes, a higher prevalence of smoking was observed in participants with lower levels of spiritual health (P < 0.004). In men, compared to those with a low level of spiritual health (the first tertile), the logarithm of the ACC-AHA risk score was reduced by 0.11 (P = 0.004) and 0.18 (P < 0.001) for those in the second and third tertiles of spiritual health, respectively. This result may be attributed to higher cigarette smoking among the latter group. Similar results were not observed in women.Conclusions:Current results indicate a gender-specific association between spiritual health and cardiovascular disease risk. Our findings imply that promoting spiritual health can be considered an effective strategy in future preventive interventions, primarily by controlling the desire to smoke in men.  相似文献

The present study investigated the effects of aerial parts of Phlomis anisodonta methanolic extract (PAE) on streptozotocin (STZ)-induced diabetic rats by measuring fasting blood glucose, serum insulin, change in body weight, ferric reducing antioxidant power (FRAP), lipid peroxidation (LPO), and liver antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx). Male Wistar rats were randomly divided into six groups of six animals. Treatment of diabetic rats with oral administration of PAE at doses of 100, 200 and 400 mg kg(-1) for 10 days resulted in a significant reduction in fasting blood glucose, and an increase in serum insulin levels in comparison with diabetic control group. PAE also protected rats from STZ-induced loss in body weight. Hepatic FRAP increased and LPO in diabetic rats decreased after treatment by PAE at doses of 200 and 400 mg kg(-1). PAE-treated diabetic rats at three doses indicated a significant increase in hepatic SOD, CAT, and GPx activities. These results suggest that PAE is beneficial in the control of diabetes by reduction of blood glucose and increasing insulin levels and combating oxidative stress by activation of hepatic antioxidant enzymes.  相似文献

OBJECTIVE: To explore factors affecting recruitment and retention of pharmacists in rural/remote areas of New South Wales (NSW). DESIGN: Qualitative semistructured in-depth interviews. SETTING: Primary care--rural/remote community pharmacies. PARTICIPANTS: Purposive sample of 12 community pharmacists. MAIN OUTCOME MEASURES: Factors affecting recruitment and retention of pharmacists in rural/remote areas of NSW. RESULTS: Respondents reported a variety of personal and professional reasons for taking up rural practice, including previous rural experience and a preference for working in rural over metropolitan areas. The main factor affecting retention in rural areas was the high level of professional satisfaction and interprofessional rapport. Perceived reasons for the current under-supply of pharmacists to rural/remote areas of NSW included changing demographics of the pharmacy undergraduate degree programs and pharmacy workforce, and negative perceptions of rural pharmacy practice and rural lifestyle. CONCLUSIONS: This study identified factors believed to affect recruitment and retention of pharmacists in rural/remote areas. There appears to be considerable overlap between the factors, with different weightings of importance for different individuals. The lack of consensus for a proposed method of resolving this problem highlights its complexity and the need for further studies in this area.  相似文献

Malignant melanoma is an aggressive form of skin cancer that is highly resistant to conventional therapies. The melanoma inhibitor of apoptosis protein is a potent inhibitor of apoptosis and is overexpressed in melanoma cells, but undetectable in most normal tissues including melanocytes. We designed 20-mer phosphorothioate antisense oligonucleotides complementary to five putatively single-stranded sites on the melanoma inhibitor of apoptosis protein mRNA and investigated their ability to sensitize G361 melanoma cells to cisplatin. Inhibition of melanoma inhibitor of apoptosis protein mRNA and protein expression were measured by real-time polymerase chain reaction and immunoblotting. Cell viability and apoptosis were quantitated by colorimetric viability assays and by annexin V staining, respectively. Oligonucleotide M706 was identified as the most efficient antisense sequence which downregulated melanoma inhibitor of apoptosis protein mRNA and protein levels in G361 cells by 68 and 78%, respectively. The specificity of target downregulation was confirmed using scrambled sequence control oligonucleotides that only marginally decreased melanoma inhibitor of apoptosis protein expression. Whereas downregulation of melanoma inhibitor of apoptosis protein moderately inhibited cell growth by 26%, in combination with cisplatin, this resulted in a supra-additive effect with almost 57% reduction in G361 cell viability compared with cisplatin alone (17%) (P<0.05). Cell death was mainly due to apoptosis as demonstrated by a 3- to 4-fold increase in annexin V-positive cells and typical morphological changes compared with controls. In summary, we describe a new antisense oligonucleotide that efficiently downregulates melanoma inhibitor of apoptosis protein expression and sensitizes melanoma cells to cisplatin.  相似文献

Objectives:

To determine the cause of severe, disabling, groin pain.

Methods:

We describe in this case report 2 patients with severe groin pain. Two myoma-like masses were found on the uterus near the right round ligament. Both masses were excised via laparoscopy.

Results:

The pathology report of these 2 cases indicated adenomyosis. Both patients were asymptomatic after the procedure. Adenomyosis usually propagates in the myometrium, and the nodular shape of this pathology is rare. In patients with severe groin pain (menstrual or continuous), the gynecologist should think about both endometriosis of the round ligament and adenomyosis near the round ligament.

Conclusion:

Severe groin pain is rare but disabling. Endometriosis of the external part of the round ligament is described as a cause. In this case report, we explain that nodular adenomyosis can also be a cause.  相似文献
