Purpose: Injuries are one of the leading causes of death and lead to a high social and financial burden. Injury patterns can vary significantly among different age groups and body regions. This study aimed to evaluate the relationship between mechanism of injury, patient comorbidities and severity of injuries.
Methods: The study included trauma patients from July 2016 to June 2018, who were admitted to Sina Hospital, Tehran, Iran. The inclusion criteria were all injured patients who had at least one of the following: hospital length of stay more than 24 h, death in hospital, and transfer from the intensive care unit of another hospital. Data collection was performed using the National Trauma Registry of Iran minimum dataset.
Results: The most common injury mechanism was road traffic injuries (49.0%), followed by falls (25.5%). The mean age of those who fell was significantly higher in comparison with other mechanisms (p < 0.001). Severe extremity injuries occurred more often in the fall group than in the vehicle collision group (69.0% vs. 43.5%, p < 0.001). Moreover, cases of severe multiple trauma were higher amongst vehicle collisions than injuries caused by falls (27.8% vs. 12.9%, p = 0.003).
Conclusion: Comparing falls with motor vehicle collisions, patients who fell were older and sustained more extremity injuries. Patients injured by motor vehicle collision were more likely to have sustained multiple trauma than those presenting with falls. Recognition of the relationship between mechanisms and consequences of injuries may lead to more effective interventions. 相似文献

BackgroundPeripartum hysterectomy (PPH) is one of the effective treatment modalities which is increasingly performed to save the life of pregnant women with uncontrollable severe postpartum hemorrhage. The aim of this study was to assess the prevalence and factors associated with PPH among Iranian pregnant women.MethodsIn a retrospective study, 33 pregnant women with PPH referred to Imam Khomeini Hospital in Sari, Mazandaran province, northern Iran were enrolled. Data were collected using census sampling from March 2017 to 2020. Patients'' sociodemographic and clinical characteristics were collected. Fisher''s exact test, Kruskal-Wallis, and Mann-Whitney tests were used to evaluate the study variables.ResultsThe prevalence of PPH among Iranian pregnant women was 2.81 per 1000 deliveries. The mean length of stay in the hospital and intensive care unit (ICU) was 6.15 (SD=2.91) and 3.17 (SD=1.50) days, respectively. Of the participants, 90.9% had a cesarean section, 51.6% had emergency PPH, 88.2% had emergency PPH in 24 hours after delivery, 9.1% had an induction, and 60.6% had PPH due to placental abnormalities. The mean duration of PPH procedure was 2.51 (SD=1.14) hours. The most common post-operative complication in participants was fever. Participants with older gestational age had more elective PPH (P=0.029). The length of ICU stay was more in patients with total PPH procedure compared to the supracervical (P<0.017). The induction rate was higher in emergency PPH after vaginal delivery compared to cesarean section (P=0.005).ConclusionThis study showed a high prevalence of PPH among pregnant women. Also, there was a significant relationship between the PPH and length of ICU stay, especially after supracervical hysterectomy. The results of this study can help obstetrician-gynecologist to provide a better intervention for managing patients with postpartum hemorrhage requiring PPH. 相似文献

An automated sleep staging based on analyzing long-range time correlations in EEG is proposed. These correlations, indicating time-scale invariant property or self-similarity at different time scales, are known to be salient dynamical characteristics of stage succession for a sleeping brain even when the subject suffers a destructive disorder such as Obstructive Sleep Apnea (OSA). The goal is to extract a set of complementary features from cerebral sources mapped onto the scalp electrodes or from a number of denoised EEG channels. For this purpose, source localization/extraction and noise reduction approaches based on Independent Component Analysis were used prior to correlation analysis. Feature extracted segments were then classified in one of the five classes including WAKE, STAGE1, STAGE2, SWS and REM via an ensemble neuro-fuzzy classifier. Some techniques were employed to improve the classifier’s performance including Scaled Conjugate Gradient Method to speed up learning the ANFIS classifiers, a pruning algorithm to eliminate irrelevant fuzzy rules and the 10-fold cross-validation technique to train and test the system more efficiently. The performance of classification for two strategies including (1) feature extraction from effective cerebral sources and (2) feature extraction from selected channels of denoised EEG signals was compared and contrasted in terms of training errors and test accuracies. The first and second strategies achieved 92.23 and 88.74% agreement with human expert respectively which indicates the effectiveness of the staging system based on cerebral sources of activity. Our results further indicate that the misclassification rates were almost below 10%. The proposed automated sleep staging system is reliable due to the fact that it is based on the underlying dynamics of sleep staging which is less likely to be affected by sleep fragmentations occurred repeatedly in OSA. 相似文献

The present study aimed to investigate the applicability of Universal Thermal
Climate Index (UTCI) as an innovative and science-based index in public health researches,
in occupational heat stress assessment. All indoor and outdoor workers (200 people) of
Brick industries of Shahroud, Iran participated in the research. First, the environmental
variables such as air temperature, wet-bulb temperature, globe temperature, air velocity
and relative humidity were measured; then UTCI and WBGT (wet-bulb globe temperature)
indices were calculated. Simultaneously, physiological parameters including systolic and
diastolic blood pressure, oral temperature, skin temperature, tympanic temperature and
heart rate of workers were measured. UTCI and WBGT indices were 34.2 ± 2°C, 21.8 ± 1.8°C
in the outdoor environments and 38.1 ± 4.4°C, 24.7 ± 3.3°C at the indoor environments,
respectively. There were the weak inverse relationships between UTCI and WBGT indices at
the outdoor environments and physiological responses such as systolic blood pressure, and
diastolic blood pressure. However, there were no similar results for indoor environments.
The significant relationships were found between UTCI and WBGT at both indoor and outdoor
environments. Both UTCI and WBGT indices are suitable for assessing the occupational heat
stress. Although, UTCI index seems more appropriate for heat stress assessment in the
environments with low humidity and air velocity. 相似文献

The radioprotective effect of Achillea millefolium L (ACM) extract was investigated against genotoxicity induced by ionizing radiation (IR) in human lymphocytes. Peripheral blood samples were collected from human volunteers and incubated with the methanolic extract of ACM at different concentrations (10, 50, 100, and 200 μg/mL) for 2 hours. At each dose point, the whole blood was exposed in vitro to 2.5 Gy of X-ray and then the lymphocytes were cultured with mitogenic stimulation to determine the micronuclei in cytokinesis-blocked binucleated cell. Antioxidant capacity of the extract was determined using free radical-scavenging method. The treatment of lymphocytes with the extract showed a significant decrease in the incidence of micronuclei binucleated cells, as compared with similarly irradiated lymphocytes without any extract treatment. The maximum protection and decrease in frequency of micronuclei were observed at 200 μg/mL of ACM extract which completely protected genotoxicity induced by IR in human lymphocytes. Achillea millefolium extract exhibited concentration-dependent radical-scavenging activity on 1,1-diphenyl-2-picryl hydrazyl free radicals. These data suggest that the methanolic extract of ACM may play an important role in the protection of normal tissues against genetic damage induced by IR. 相似文献

Mexico has long been recognized as one of the world's cradles of domestication with evidence for squash (Cucurbita pepo) cultivation appearing as early as 8,000 cal B.C. followed by many other plants, such as maize (Zea mays), peppers (Capsicum annuum), common beans (Phaseolus vulgaris), and cotton (Gossypium hirsutum). We present archaeological, linguistic, ethnographic, and ethnohistoric data demonstrating that sunflower (Helianthus annuus) had entered the repertoire of Mexican domesticates by ca. 2600 cal B.C., that its cultivation was widespread in Mexico and extended as far south as El Salvador by the first millennium B.C., that it was well known to the Aztecs, and that it is still in use by traditional Mesoamerican cultures today. The sunflower's association with indigenous solar religion and warfare in Mexico may have led to its suppression after the Spanish Conquest. The discovery of ancient sunflower in Mexico refines our knowledge of domesticated Mesoamerican plants and adds complexity to our understanding of cultural evolution. 相似文献
