Abstract
Importance Although maternal unintentional injury during pregnancy has shown negative impacts on the mother and fetus, the evidence on its long-term associations with children's neurodevelopment is limited. Objective To examine the association between maternal unintentional injury and cerebral palsy (CP) in offspring. Design, Setting, and Participants This was a population-based, longitudinal, cohort study of all in-hospital live births born between April 1, 2002, and March 31, 2017, in a publicly funded health care system setting of Ontario, Canada. Infants born more than 20 weeks' gestation were included and followed up until March 31, 2018. Excluded from the analysis were stillbirths, infants with missing or invalid records, and births with missing or invalid birth characteristics. Data were analyzed from March 1 to June 30, 2021. Exposures Maternal unintentional injury during pregnancy ascertained based on inpatient or emergency department diagnoses. Main Outcomes and Measures CP diagnosis between birth and the end of follow-up in 2018 with the CP case definition of a single inpatient or 2 or more outpatient diagnoses at least 2 weeks apart between birth and age 16 years. Results Of 2 110 177 children included in this study (mean [SD] gestational age, 38.8 [1.9] weeks; 1 082 520 male [51.3%]), 81 281 (3.9%) were exposed in utero to maternal unintentional injury. During a median (IQR) follow-up time of 8 (4-12) years, 5317 children (0.3%) were diagnosed with CP (292 CP cases [5.5%] were exposed to maternal unintentional injury). The mean incidence rates of CP were 4.36 and 2.93 per 10 000 child-years in the exposed and the unexposed group, respectively. Children exposed to maternal unintentional injury had a modest increase in the risk of CP, compared with those unexposed (hazard ratio [HR], 1.33; 95% CI, 1.18-1.50) after adjusting for maternal sociodemographic and clinical characteristics. Severe injuries that resulted in hospitalization and delivery within 1 week from the injury conferred higher risks of CP (adjusted HR, 2.18; 95% CI, 1.29-3.68 and adjusted HR, 3.40; 95% CI, 1.93-6.00, respectively). Results were robust in multiple bias analyses. Conclusions and Relevance In this Canadian population-based birth cohort study, in utero exposure to maternal unintentional injury was associated with an increased risk of CP, with a higher risk with more severe injuries. These findings fill an important gap in knowledge on the potential role of maternal injury on children's neurodevelopment outcomes. Public health professionals and stakeholders should be aware of these potential long-term consequences on offspring when designing programs and providing recommendations about safety during pregnancy. Early monitoring and developmental assessment of children exposed to maternal injury might be warranted.

Abstract
Introduction Blunt traumas, like road accidents and falls, are common causes of injuries to pregnant women, and the major risk factors are young age and low socioeconomic level. Due to physiological and anatomical changes specific to pregnancy, such as changes in blood pressure and hemoglobin drop, trauma management involves certain complexities. Physical trauma is estimated to cause at least 1 complication in every 12 pregnancies. This study aims to evaluate orthopedic trauma during pregnancy and appreciate the different approaches to circumvent the resultant challenges. Methods We reviewed 55 articles, published on orthopedic trauma during pregnancy between 2011 and 2021. The articles were identified by searching PubMed, google-scholar, Scopus, and Science-Direct. We utilized the search terms: fall in pregnancy, traumas in pregnancy, motor vehicle accident/crash in pregnancy, blunt trauma in pregnancy, pregnant trauma patient, penetrating injury during pregnancy, assault, interpersonal violence in pregnancy, and mortality and pregnancy. Results According to available reports, after stabilizing the pregnant patient, diagnostic procedures, including radiography, and even gadolinium-based techniques when needed, can be performed to examine extensive trauma. In contrast to elective orthopedic surgery, emergency orthopedic surgeries, including reduction of open fractures, should be performed promptly. Conclusion Based on our investigation, pregnant women with orthopedic injuries that are severe, or even seemingly less severe, experience significantly increased adverse pregnancy outcomes, which include preterm birth, placental abruption, poor infant condition at birth, infant death, and even maternal death.

Trauma and pregnancy: Is flow cytometry detection and quantification of fetal red blood cells useful? Eur J Obstet Gynecol Reprod Biol 2021; 266:48-54. [PMID: 34592649 DOI: 10.1016/j.ejogrb.2021.09.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 08/19/2021] [Accepted: 09/13/2021] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To assess whether positive flow cytometry quantification of fetal red blood cells is associated with adverse maternal and neonatal outcomes in cases of mild trauma during pregnancy. STUDY DESIGN A retrospective database study was conducted at a single tertiary center between 2013 and 2019. All pregnant women with viable gestation involved in trauma who underwent flow cytometry quantification of fetal red blood cells were included in the study. Flow cytometry was considered positive (≥0.03/≥30 ml). Composite adverse maternal and neonatal outcome was defined as one or more of the following: intrauterine fetal death, placental abruption, pre-term birth <37 weeks of gestation, immediate premature rupture of the membranes, and immediate delivery following trauma. Univariate analysis was performed followed by multivariate logistic regression analysis controlling for potential confounders, to assess the role of flow cytometry in predicting adverse maternal and neonatal outcome. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated. RESULTS During the study period 1023 women met inclusion and exclusion criteria. The mechanisms of injury were motor vehicle accident in 387 women (38%), falls in 367 (36%), direct abdominal injury in 353 (35%) and in 14 women (1%) other mechanism of injury. Flow cytometry was considered positive (≥0.03/≥30 ml) in 119 women (11.6%) with median result of 0.03 [0.03-0.04], and negative in 904 women (88.4%) ((≤0.03/≤30 ml) with median result of 0.01 [0.01-0.02]. Composite adverse outcome occurred in 8% of the women involved in trauma during pregnancy, with no difference between the groups with vs. without positive flow cytometry (4.2% vs. 8.5%; p = 0.1). Positive flow cytometry was not associated with any adverse maternal or neonatal outcome. This was confirmed on multivariate analysis controlling for potential confounders. CONCLUSION Flow cytometry result is not related to adverse maternal and fetal/neonatal outcome of women involved in minor trauma during pregnancy. We suggest that flow cytometry should not be routinely assessed in pregnant women involved in minor trauma.

Abstract
INTRODUCTION Falls during pregnancy occur in 25-27% of women and can cause serious harm to both the mother and the fetus. The objective of this systematic review was to identify intrinsic and extrinsic risk factors for falls during pregnancy by reviewing original studies and addressing possible forms of prevention. METHODS We searched PubMed, Cochrane library, and Web of Science databases for studies assessing risk factors for falling after a fall has occurred or by using posturographic assessment. RESULTS Fourteen studies were included in the review. The identified extrinsic risk factors include slippery floors, cluttered areas, uneven ground, inappropriate shoes, hurrying, walking on stairs, carrying additional loads, poor lighting or obstructed view, sedentary lifestyle and working in physically demanding jobs. The identified intrinsic factors include age less than 30, height more than 160 cm, advanced pregnancy, unintended pregnancy, multiparity, hyperemesis gravidarum, low back pain, gestational diabetes, increase in abdominal circumference, lower ankle stiffness and joint laxity. Physical activity, maternity support belts, and education are possible strategies for fall prevention. CONCLUSION Our systematic review identified 13 intrinsic and 11 extrinsic risk factors for falling during pregnancy. With the knowledge of risk factors and the optimal prevention strategy, healthcare providers could incorporate this information in the treatment of pregnant women and reduce the risk of falling.

Abstract
Literature regarding pregnant women who sustained traumatic spinal injury during pregnancy is limited. Existing papers are mainly case reports, and this indicates a need for more high-quality research evidence in this area. Therefore, this study was designed to systematically review available literature that reported demographic information, clinical characteristics, and obstetric outcomes of women who sustained spinal injury during pregnancy. Studies published from the earliest record to January 2019, which reported traumatic spinal injury during pregnancy, were included. Studies that have reported pregnancy in patients with pre-existing spinal injury, review articles, commentaries, letter to editors, conference papers, and studies published in languages other than English were excluded. Sixteen studies reporting on 26 women were included. Their mean age was 26.7±5.5 years. Motor vehicle accidents were the main cause of spinal injury (n=15, 58%). Of the cases, four women sustained spinal injury during the 1st trimester of pregnancy, of which one had a spontaneous abortion, one delivered a baby with arthrogryposis multiplex congenital disorder, and the third one delivered a premature baby who died shortly after the delivery. Fifteen women sustained injury during their 2nd trimester, of which 14 delivered normal babies, while six sustained spinal injury during the 3rd trimester. Of these women, five delivered normal babies at term. Outcomes of pregnancy appear significantly affected if a spinal injury occurs during the 1st trimester of pregnancy; however, injuries sustained during the 2nd and 3rd trimesters can have good obstetric outcomes.

Abstract
OBJECTIVES Falls are one of the leading causes of trauma during pregnancy, and most falls occur on stairs. The purpose of this study was to describe stair-related falls among pregnant women who were treated in United States emergency departments during a 10-year period. METHODS This study utilized a cross-sectional analysis of National Electronic Injury Surveillance System (NEISS) data, 2008-2017. Emergency department visits by pregnant women aged 12 years and older were identified using case narratives. RESULTS From 2008 to 2017, 1466 cases of pregnant women who had sustained stair-related falls were reported to NEISS, equating to a national estimate of 57,512 over the 10-year study period. Variables examined included age, body part injured, location of injury, discharge disposition, gestation, mechanism of injury, and other fall-associated hazards and symptoms. Most injuries involved contusions or abrasions, other injuries commonly reported were sprains/strains and contusions/abrasions. Wet/icy conditions represented hazards associated with 4.1% of all injuries. Severe obstetric symptoms, such as decreased fetal movement and vaginal bleeding, were described in study narratives. CONCLUSIONS Falls are a leading cause of injury among women of childbearing age and stair-related falls comprise a large proportion of maternal falls. Physiological changes associated with pregnancy can put gravid women at greater risk for falls. Healthcare providers can provide women anticipatory guidance that may reduce their risk for falls as they progress in pregnancy.

Abstract
BACKGROUND Trauma is the leading cause for nonpregnancy-linked maternal mortality in pregnant women, even though the exact incidence for accidents in pregnancy is unknown. Trauma management concepts applied for nonpregnant adult patients are just as valid for injured and severely injured pregnant women but in addition trauma management has to consider the unique physiological and pathophysiological conditions for a favorable maternal and fetal outcome. OBJECTIVE Overview of current data about the epidemiology, injury mechanisms, maternal and fetal outcome and recommendations on the management of injured pregnant women based on a systematic literature search. RESULTS Currently, there is no evidence indicating an association between maternal injury severity, the physiological condition and the fetal outcome. Practice guidelines for trauma management in pregnancy recommend prioritization of maternal treatment and resuscitation for optimal initial treatment of the fetus. The current recommendations for trauma room management in pregnancy, surgical treatment, including damage control surgery, are based on weak evidence. CONCLUSION The examination, stabilization and treatment of injured pregnant women has priority for fetal survival and outcome. The management of severe trauma in pregnancy requires a multidisciplinary expertise and team approach consisting of surgeons, anesthetists, radiologists, obstetricians and neonatologists, so that for a severely injured gravida, the decision for admission to designated trauma centers is already preclinically made. The principles of management and treatment of severely injured pregnant women should adhere to the treatment principles of nonpregnant trauma victims.

Abstract
Introduction Injury is a leading cause of morbidity and mortality globally and disproportionately affects low-income countries. While most injury data comes from tertiary care centers in urban settings, the purpose of this study was to describe the characteristics and severity of injury in rural Uganda and the associated treatment patterns and delays in care. Methods This is a retrospective cohort study of a trauma registry that was implemented at Masindi-Kitara Medical Center (MKMC), a rural hospital in Western Uganda. Demographic information, injury characteristics, modified Kampala Trauma Scores (M-KTS), and treatment modalities over a 12 month period were retrospectively collected from paper-based registry forms completed for all injury patients presenting to MKMC. Results A total of 350 patients were entered into the trauma registry. Most patients were male (71.2%) with a median age of 26.5 years. Motorcycle crashes were the most prevalent mechanism of injury (42.3%) with the majority being unhelmeted (83.3%). Soft tissue injury was the most common diagnosis (44.9%). Patients were frequently treated in the outpatient department and then discharged (54.8%). Patients requiring admission or transfer (M-KTS = 11.57 or 11.67) tended to have a lower M-KTS than discharged patients (M-KTS = 12.75). Analgesics (74.6%) and antibiotics (52.9%) were the most common treatments administered. For those patients requiring admission (29.4%), only one in-hospital death was documented. Thirty-nine percent of patients reported a delay in seeking care, most frequently due to lack of transportation (31.5%) with a median time of delay of 11 h. Conclusion Road traffic injuries were the leading cause of injury in Masindi, with a high proportion of injuries associated with unhelmeted motorcycle crashes. Future opportunities to prevent injury and improve care may be seen through improved prehospital care, enforcement of helmet laws, increased access to neurosurgical services, and enactment of hospital quality improvement measures.

Abstract
BACKGROUND Diabetes can cause biomechanical alterations that may be responsible for additional changes to those existing in a regular gestational period. The way a maternal body responds when affected by diabetes has not been clearly understood. This study aimed to describe the influence of type 1 diabetes on pregnant women's postural control. METHODS Forty pregnant women in their third gestational trimester were allocated in two equal groups - the control group and the type 1 diabetic group. The variables related to postural control and balance were assessed using photogrammetry (head protrusion; cervical lordosis; thoracic kyphosis; lumbar lordosis; pelvic anteversion, knee flexion, tibiotarsal and foot inclination angles were measured), and baropodometry (anteroposterior and mediolateral distance trajectory of the center of pressure, amplitude and average speed of displacement of the center of pressure). FINDINGS The results of the type 1 diabetic group showed, in the postural analysis, lower head protrusion and pelvic anteversion angles, while there was higher cervical lordosis, thoracic kyphosis, and lumbar lordosis angles. In the baropodometry, the anteroposterior distance and the amplitude of the center of pressure displacement with eyes open and closed were higher. INTERPRETATION The findings suggest that type 1 diabetes mellitus in the third trimester of pregnancy is associated with postural changes, a decrease in the active ankle range of motion and increase in the anteroposterior oscillation of the center of pressure, with negative repercussions for postural control.

Obstetric Correlates of Maternal Falls in Southern Nigeria. ScientificWorldJournal 2019; 2019:9716919.

Abstract
Falls during pregnancy can be associated with serious obstetric complications. Apart from sparse data highlighting traumatic outcomes, there are no studies identifying the obstetric correlates of maternal falls in Nigeria. A cross-sectional cohort survey of 1,175 women in five public health facilities in Ado–Ekiti was conducted to address this need. Fall rate was 25%; mothers who fell during pregnancy were significantly older, of higher parity, and with unintended/unwanted pregnancies than those who did not fall. Most of the reported falls occurred in the third trimester, with about 10% of the women falling at least thrice during the course of the pregnancy. More than half of the reported falls occurred while engaging in household chores and carrying child/object with compromised visibility of the feet and floor. Uterine contractions/abdominal pain was the commonest; 29 (76.3%), obstetric event attributed to the falls. Antepartum haemorrhage, 4 (10.5%), and ruptured membranes, 2 (5.3%), also occurred after falls, although it was rare and occurred with the same frequency as in the general population. Maternal age ≥ 30 years (odds ratio: 1.36; 95% C.I. 1.03 – 1.80, p = 0.031), multiparity (odds ratio: 1.54; 95% C.I. 1.15 – 2.07, p = 0.004), unintended pregnancy (odds ratio: 1.48; 95% C.I. 1.02 – 2.15, p = 0.037), and delivery age ≤ 40 weeks (odds ratio: 1.71; 95% C.I. 1.07 – 2.75, p = 0.026) were found to be independent risk factors for falls during pregnancy. Fall awareness campaigns and fall-preventing safety tips are advocated in women's clinics. Improving contraceptive uptake will reduce unintended pregnancies and the risk of pregnancy-related fall/injuries.

Abstract
It is believed that hormonal changes during pregnancy lead to an increased compliance in ligaments and tendons, increasing the risk to suffer from connective tissue injuries particularly during exercise. While the laxity of the pelvic ligaments may increase to facilitate childbirth, to our knowledge no study has ever investigated the mechanical properties of human tendons in different stages of pregnancy. Thus, the purpose of our longitudinal study was to investigate the mechanical properties of the patellar tendon in different stages of pregnancy and postpartum. Nineteen pregnant women (30 ± 4 years) and 11 non-pregnant controls (28 ± 3 years) performed maximum isometric knee extension contractions on a dynamometer. Muscle strength and mechanical properties of the patellar tendon were determined integrating ultrasound, kinematic, and electromyographic measurements. In pregnant women, measurements were performed in the 16 ± 4th week of pregnancy (EP), the 29 ± 4th week of pregnancy (LP) and 32 ± 9th weeks postpartum (PP). On average, muscle strength as well as patellar tendon stiffness, force, and relative strain did not change during pregnancy and did not differ from non-pregnant controls. Tendon length measured at 90° knee flexion continuously increased during and after pregnancy (tendon length PP>EP; PP>controls). Our results indicate that patellar tendon stiffness is not universally affected by pregnancy. We found no evidence to support the often stated assumption that tendons would become more compliant during pregnancy. However, variability between individuals as well as the progressive increase in tendon rest length during and after pregnancy and its implications on injury risk need to be further examined.
