RESUMO
OBJECTIVE: Although recent trends from the Accreditation Council for Graduate Medical Education (ACGME) present encouraging growth of female representation in sports medicine, the field is still lagging behind other specialties. This study investigates gender disparities among physicians providing care for professional sports teams in male and female sports leagues. DESIGN: Information regarding physicians providing sports medicine care to professional teams obtained by database queries (May 2021). Chi-square analysis compared gender data of orthopaedic team physicians with American Orthopaedic Society for Sports Medicine (AOSSM) and American Academy of Orthopaedic Surgeons (AAOS) membership, residency, and fellowship census data. Primary care sports medicine physicians were compared with American Medical Society for Sports Medicine (AMSSM) and primary-care sports medicine fellowship census data. SETTING: Professional sports health care. STUDY POPULATION: Professional league physicians. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Gender, residency, and fellowship training of professional league physicians. RESULTS: Among a total of 608 team physicians, 572 (93.5%) were male and 40 (6.5%) were female. Orthopedic surgeons comprised 64.7% of the physicians. Fourteen (3.6%) team orthopedic surgeons were female. Thirty-five percent of team physicians were primary care sports medicine physicians. Twenty-six primary care sports medicine physicians (11.6%) were female. Orthopaedic female team physician representation overall was comparable with AOSSM and AAOS membership but significantly less than orthopaedic surgery residents and sports medicine fellows ( P < 0.01). Women's National Basketball Association orthopaedic team physicians were more represented than female membership among AOSSM, AAOS, and orthopaedic sports medicine fellows ( P < 0.01). Except for the WNBA, Premiere Hockey Federation, National Women's Soccer League, and United States Football League, female primary care sports medicine physicians were underrepresented in professional sports compared with AMSSM membership and primary care sports fellows ( P < 0.01). CONCLUSION: Overall, female representation is poor among orthopaedic surgeons and primary care physicians providing sports medicine care to professional teams. Leagues encompassing female athletes tend to have better representation of female physicians. LEVEL OF EVIDENCE: IV.

INTRODUCTION: Human immunodeficiency virus (HIV) positive patients are at high risk for osteonecrosis along with age-related osteoarthritis, resulting in a high number of joint reconstruction surgeries at younger ages in these immunosuppressed patients. Few previous studies have reported on patient outcomes in HAART (highly active antiretroviral therapy) compliant patients undergoing primary arthroplasty. The aim of this study is to report one institution's overall rate of complications and revision in HAART-compliant patients after primary hip and knee arthroplasty. METHODS: A retrospective chart review was performed spanning a 4 year period. This study included 50 primary joint arthroplasty patients diagnosed with HIV including 13 TKA (total knee arthroplasty) and 37 THA (total hip arthroplasty) with a prior diagnosis of HIV infection. Preoperative CD4 count and viral loads were recorded. Charts were reviewed for post-operative complications including infection and revision. RESULTS: The were a total of 11 postoperative complications (22%). There were 3 cases (6%) of soft tissue infection, 3 cases (6%) of implant loosening, 2 cases (4%) of dislocation, 1 case (2%) of lower extremity weakness, 1 case (2%) of venous thrombosis, and 1 case (2%) of arthrofibrosis. Of all patients, there were 6 cases of revision in this cohort (12%), 5 of which were aseptic etiology. All 3 infected patients had a history of IVDU. Two of these infected patients resolved with IV antibiotics while 1 underwent two-stage revision (2%). Patients that experienced post-operative complications had significantly elevated preoperative CD4 levels (983 versus 598, p = 0.003). CONCLUSION: Arthroplasty is a viable option for HAART-compliant patients. Most previous studies showing a higher risk for deep tissue infection and revision in HIV patients have not accounted for modern HAART. Our results show that compliance with HAART has vastly improved the outcomes of arthroplasty in these patients, while a history of IVDU is likely the largest risk factor for infection in this population.

PURPOSE: A relatively high expense with any procedure is total operative time; two components being the time spent anesthetizing the patient and time spent transferring the patient out of the operating room (OR). Both times can be affected by the anesthetic method used. This study compares different operative time intervals for both spinal anesthesia (SA) and general anesthesia (GA), in patients undergoing a primary total hip arthroplasty (THA), to identify the most appropriate and cost-effective anesthetic method. METHODS: A retrospective chart review was performed at a single institution for primary total hip arthroplasty procedures performed in the year 2019. Primary THAs without complications performed by three orthopedic surgeons were selected. Anesthesia records for 200 patients were used to compare perioperative time intervals; 100 consecutive patients that received SA and 100 consecutive patients that received GA. RESULTS: The time spent transferring the patient out of the operating room was 8 min for GA and 5 min for SA (p < 0.001). Total operative time for GA was 90 min and 87 min for SA (p = 0.3330). Total pre-operative time averaged 26 min in SA compared to 25 min in GA (p = 0.5874). Non-operative total time (all time components of patient interaction excluding surgery start to surgery finish) was significantly shorter in SA with an average of 52 compared to 56 in GA (p = 0.0151). CONCLUSION: Time to transfer patient out of the OR and total non-operative time was significantly shorter in patients who received spinal anesthesia. These results and the complications of both general and spinal anesthesia should be taken into consideration when anesthetizing patients undergoing primary THA. LEVEL OF EVIDENCE: III.

INTRODUCTION: There is a paucity of information on the bone remodeling that occurs distal to the femoral stem following total hip arthroplasty as most previous studies have focused on proximal changes. In this study, we report the cortical thinning that occur distal to the femoral stem after primary total hip arthroplasty. METHODS: A retrospective review was performed at one institution over a 5-year period. 156 primary total hip arthroplasty procedures were included. The Cortical Thickness Index (CTI) was measured on both operative and non-operative hips at 1 cm, 3 cm and 5 cm below the prosthetic stem tip on anteroposterior radiographic images pre-operatively as well as at 6 months, 12 months and 24 months post-operatively. The difference in average CTI was measured using paired t-tests. RESULTS: There were statistically significant decreases in CTI distal to the femoral stem at 12 months and 24 months (-1.3% and -2.8%, respectively). Greater losses were seen in female patients, patients older than 75, and patients with BMI less than 35 at 6 months postoperative. There were no differences in CTI at any time point on the non-operative side. CONCLUSION: The current study demonstrates that patients undergo bone loss as measured by CTI distal to the stem in the first 2 years following total hip arthroplasty. Comparison to the contralateral non-operative side confirms that this change is greater than expected for the natural aging process. A greater understanding of these changes will help optimize post-operative management and direct future innovations in implant design.

The goal of this study was to examine whether family involvement and gender moderated daily changes in affect associated with interpersonal stressors. Adults (N = 2022; M age = 56.25, Median = 56, SD = 12.20, Range = 33-84) from the second wave of the National Study of Daily Experiences participated in eight consecutive daily diaries. Each day they reported whether a daily interpersonal stressor occurred, whether family was involved, and their positive and negative affect. Results from multilevel models indicated that family involvement did not significantly moderate daily interpersonal stressor-affect associations; however, gender was a significant moderator in some instances. Women showed greater increases in negative affective reactivity to arguments and avoided arguments compared to men. Further, compared to men, women reported larger decreases in positive affective reactivity, but only for avoided arguments. Neither family involvement, gender, nor the interaction between family involvement and gender predicted affective residue. Gender differences in daily interpersonal stressors and affective reactivity may be attributable to overarching gender norms and roles that are still salient in the U.S. Our results suggest that daily interpersonal stressors may be detrimental to affective well-being, regardless of family involvement. Future work should explore associations between daily interpersonal stressors and family involvement by specific relationship roles, such as mother or spouse, for a more comprehensive understanding of what stressor characteristics impact daily affective well-being.
RESUMO
Early childhood teachers play a central role in children's learning and development. Yet, they encounter stressors that can negatively impact their well-being, relationships with children, and, ultimately, job retention. To inform efforts to support early childhood teachers' work-related well-being, the current study examines positive factors that predict work engagement. Participants were 50 early childhood teachers from Head Start (34%), center-based programs (32%), and licensed home-based programs (34%). Consistent with a resilience framework and the Job Demands-Resources model, we examined both a personal resource (self-efficacy) and a workplace resource (professional support) in relation to work engagement, or the positive, fulfilling connection to one's work. Teachers' self-efficacy and professional support predicted greater work engagement, accounting for job demands (teachers' compassion fatigue/work distress and children's challenging behaviors) and teachers' education and professional development. Although not causal, findings are suggestive that supporting early childhood teachers with what they need to do their job effectively and feel that they can make meaningful differences in children's lives may help them to engage in their work with passion, dedication, and positive energy. Ultimately, supporting teachers' work engagement may in turn have developmental benefits for children as well.
RESUMO
Background: This study aimed to analyze the prescribing patterns of opioids by different categories of providers for postoperative pain after primary total hip and knee arthroplasty (THA, TKA) at a single institution. Methods: A retrospective review was conducted on 1774 patients who underwent primary THA or TKA between 2014 and 2019 at a single, level one academic trauma center. Patients were excluded for additional procedures within 90 days of the index surgery. Patient demographics, operative variables, and opioid prescriptions were collected and analyzed. Generalized linear models accounting for within-person correlations were used to model the association between patient age, prescriber, etiology, opioid category, and mean morphine milligram equivalent (MME) prescribed. Results: The mean MME prescribed per patient up to 90 days postoperatively was 1591. Significant variations were observed in prescribing habits based on patient gender, age, prescriber category, and drug type. Females were prescribed more MMEs than males (CI 8.58, 667.16; p = 0.0443) and patients 65 years or younger received higher MMEs compared to those above 65 (CI 231.11, 926.48; p = 0.0011). Non-orthopedic physicians prescribed higher MMEs than orthopedic surgeons (CI 402.76, 1219.48; p < 0.0001). Hydrocodone and oxycodone prescriptions had significantly higher MMEs than tramadol prescriptions (CI 446.33, 719.52; p < 0.0001 and CI 681.09, 1065.26; p < 0.0001, respectively). Conclusion: These findings suggest the need for standardized guidelines and interventions to address variations in opioid prescribing practices for postoperative pain control. Understanding baseline prescription habits can help guide efforts to optimize pain management and reduce opioid overprescribing in the surgical setting.
RESUMO
OBJECTIVES: Despite higher physical vulnerability to COVID-19, older adults reported less psychological stress than younger and midlife adults during the pandemic. However, little is known about age differences in stress within later life, and most COVID-19 studies have been cross-sectional. We examined weekly hassles exposure and severity trajectories and whether these trajectories differed by age, resilience factors (higher trait resilience and education) and vulnerability factors (identifying as a woman, being a person of color, and having chronic health conditions). METHOD: Community-dwelling adults aged 50+ in Oregon (Mage = 71.1, SD = 7.3; 74% women, 89% non-Hispanic White) completed weekly online surveys across eight weeks (April 28 - June 22, 2020) during the COVID-19 stay-at-home mandate. A two-part model estimated how age, resilience, and vulnerability factors predicted weekly odds of any hassle exposure and level of severity. RESULTS: Across time, hassles exposure decreased and the rate of severity declined, but these patterns differed by age and other demographics. The old-old (estimated at age 78) remained stable in odds of any exposure, while the young-old (estimated at age 64) evidenced a J-shaped curve; age did not moderate the severity slopes. Further, both resilience factors were associated with exposure trajectories, whereas vulnerability factors (race/ethnicity and chronic illness) were associated with levels of hassles severity. DISCUSSION: There were age differences in patterns of hassles during the COVID pandemic. Further, resilience and vulnerability factors also showed complex patterns, underscoring the need for future studies to focus on age differences in well-being in later life.
RESUMO
OBJECTIVES: Caregiving dynamics may shape caregivers' views on their own aging in ways that affect their (de)motivation to improve their current and future health and well-being. In this study, we investigated within-person associations of daily positive and negative caregiving appraisals, future self-views (physical functioning, cognitive, and overall health domains), and physical activity goal pursuit among adult-daughter dementia caregivers. METHODS: Data came from 33 middle-aged caregivers (M = 55.03) who participated in a 30-day microlongitudinal study of caregiving (N of occasions = 855). We used multilevel modeling to analyze within-person associations. RESULTS: Daily positive caregiving appraisals were not associated with daily future self-views. However, on days when caregivers reported higher negative caregiving appraisals, they thought more negatively about their future older selves in all domains. In turn, on days when caregivers thought more negatively about their future older selves in all domains, they reported lower physical activity goal pursuit. Future self-views in all domains mediated the association between negative caregiving appraisals and physical activity goal pursuit. Future self-views did not mediate the association between positive caregiving appraisals and physical activity goal pursuit. However, cognitive future self-views moderated the association between positive caregiving appraisals and physical activity goal pursuit. DISCUSSION: Results suggest that one pathway through which subjective caregiving experiences, especially negative caregiving appraisals, affect caregivers' physical activity goal pursuit is through future self-views. Thus, this study offers a deeper theoretical understanding of caregivers' self-regulatory health behavior and new empirical information on how caregiving might affect life-span developmental motivation.

Introduction: To evaluate the impact various levels of irradiation have on bone-patellar tendon-bone (BTB) allograft load-to-failure. Materials and methods: Pubmed, Google Scholar and Embase were searched for studies reporting load-to-failure measurements of BTB allografts following gamma or eBeam irradiation. All systematic reviews, editorials, as well as studies that utilized animal models and/or other graft sources (achilles, hamstring, quadriceps) were excluded. Meta-analysis was performed to compare the impact of low dose (19 ≤ kGy), intermediate (20-49 kGy) and high dose (>50 kGy) gamma and eBeam radiation on load-to-failure. Results: Twelve studies, containing a total of 429 BTB allografts (159 controls, 270 irradiated), were identified. Load-to-failure of BTB allograft was significantly decreased at intermediate (20-49 kGy) doses of radiation, while low (≤19 kGy) and high (>50 kGy) doses did not significantly change load-to-failure. Conclusions: Intermediate doses of radiation may negatively impact the biomechanical integrity of BTB allograft in vitro. Future studies are required to examine clinical outcomes at varying irradiation levels.
RESUMO
Follicular helper T (Tfh) cells are essential for germinal center (GC) B cell responses. However, it is not clear which PD-1+CXCR5+Bcl6+CD4+ T cells will differentiate into PD-1hiCXCR5hiBcl6hi GC-Tfh cells and how GC-Tfh cell differentiation is regulated. Here, we report that the sustained Tigit expression in PD-1+CXCR5+CD4+ T cells marks the precursor Tfh (pre-Tfh) to GC-Tfh transition, whereas Tigit-PD-1+CXCR5+CD4+ T cells upregulate IL-7Rα to become CXCR5+CD4+ T memory cells with or without CCR7. We demonstrate that pre-Tfh cells undergo substantial further differentiation at the transcriptome and chromatin accessibility levels to become GC-Tfh cells. The transcription factor c-Maf appears critical in governing the pre-Tfh to GC-Tfh transition, and we identify Plekho1 as a stage-specific downstream factor regulating the GC-Tfh competitive fitness. In summary, our work identifies an important marker and regulatory mechanism of PD-1+CXCR5+CD4+ T cells during their developmental choice between memory T cell fate and GC-Tfh cell differentiation.

The field of toxicology is on the cusp of a major transformation in how the safety and hazard of chemicals are evaluated for potential effects on human health and the environment. Brought on by the recognition of the limitations of the current paradigm in terms of cost, time, and throughput, combined with the ever increasing power of modern biological tools to probe mechanisms of chemical-biological interactions at finer and finer resolutions, 21st century toxicology is rapidly taking shape. A key element of the new approach is a focus on the molecular and cellular pathways that are the targets of chemical interactions. By understanding toxicity in this manner, we begin to learn how chemicals cause toxicity, as opposed to merely what diseases or health effects they might cause. This deeper understanding leads to increasing confidence in identifying which populations might be at risk, significant susceptibility factors, and key influences on the shape of the dose-response curve. The U. S. Environmental Protection Agency (EPA) initiated the ToxCast, or "toxicity forecaster", program 5 years ago to gain understanding of the strengths and limitations of the new approach by starting to test relatively large numbers (hundreds) of chemicals against an equally large number of biological assays. Using computational approaches, the EPA is building decision support tools based on ToxCast in vitro screening results to help prioritize chemicals for further investigation, as well as developing predictive models for a number of health outcomes. This perspective provides a summary of the initial, proof of concept, Phase I of ToxCast that has laid the groundwork for the next phases and future directions of the program.

Heightened affective and physical reactions to daily stressful events predict poor long-term physical and mental health outcomes. It is unknown, however, if an experimental manipulation designed to increase interpersonal resources at work can reduce associations between daily stressors and physical and affective well-being. The present study tests the effects of a workplace intervention designed to increase supervisor support for family and personal life and schedule control on employees' affective and physical reactivity to daily stressors in different domains (i.e., work, home, interpersonal, and noninterpersonal stressors). Participants were 102 employed parents with adolescent children from an information technology (IT) division of a large U.S. firm who participated in the Work, Family, and Heath Study. Participants provided 8-day daily diary data at baseline and again at a 12-month follow-up after the implementation of a workplace intervention. Multilevel models revealed that the intervention significantly reduced employees' negative affect reactivity to work stressors and noninterpersonal stressors, compared to the usual practice condition. Negative reactivity did not decrease for nonwork or interpersonal stressors. The intervention also did not significantly reduce positive affect reactivity or physical symptom reactivity to any stressor type. Results demonstrate that making positive changes in work environments, including increasing supervisor support and flexible scheduling, may promote employee health and well-being through better affective responses to common daily stressors at work.

Prior studies have shown that parent and adolescent cortisol are associated across days and that this covariation may be adolescent-driven. This study extends this literature by (a) testing whether parents' cognitive interference (i.e., distracting and ruminative thoughts potentially due to worry) mediates the linkages between adolescent and next-day parent cortisol and (b) whether these linkages were moderated by parent gender or warmth. Daily diary data, including bedtime cortisol, were collected on two samples of employees and their adolescent-aged children (N = 318 dyads, Myouth age = 13.18 years, 74% mothers). We tested mediation with autoregressive cross-lagged models. Moderated mediation by parent gender was found in our bedtime cortisol models. Higher adolescent bedtime cortisol levels were associated with higher next-day levels of mothers' cognitive interference. In turn, higher levels of mothers' cognitive interference were linked to higher mothers' same-day bedtime cortisol levels. These linkages were not significant for fathers. Cognitive interference did not mediate the associations between child and parent area under the curve or cortisol awakening response. No moderation was evident for parental warmth. Results suggest that mothers' cognitions play a key role in the transmission of elevated bedtime cortisol levels from adolescents to their mothers.

OBJECTIVES: The effects of the novel coronavirus on the musculoskeletal system have been reported with wide variability. The purpose of this study was to determine the prevalence of musculoskeletal symptoms and if these correlated with other patient characteristics. METHODS: This was a retrospective review of 685 admitted patients who were found to be positive for COVID-19 during their admission. Based on a standard COVID-19 questionnaire, we recorded complaints of new onset myalgias, joint pain, back pain, and muscle weakness and performed a chart review for all existing comorbidities. Statistical analyses were performed to determine the association between various comorbidities and orthopedic manifestations of COVID-19 patients. RESULTS: Of the 685 patients who tested positive for COVID-19, 186 patients presented with at least one orthopedic manifestation (27.1%). Patients that experienced orthopedic manifestations were significantly younger at 53.7 years of age compared to 58.1 years of age (p = 0.003) with a significantly higher BMI (body mass index) at 32.6 versus 30.0 (p = 0.022). Patients that had diabetes or were obese had significantly higher rates of orthopedic manifestations while those that had heart or lung disease had significantly fewer. CONCLUSION: Obese and diabetic patients had significantly higher rates of orthopedic symptoms during COVID-19 infection. Further studies need to be carried out in these populations to determine if these comorbidities during infection have an effect on the musculoskeletal system in the perioperative setting and after recovery from infection.
RESUMO
The human capacity to speak is fundamental to our advanced intellectual, technological and social development. Yet so very little is known regarding the evolutionary genetics of speech or its relationship with the broader aspects of evolutionary development in primates. In this study, we describe a large family with evolutionary retrograde development of the larynx and wrist. The family presented with severe speech impairment and incremental retrograde elongations of the pisiform in the wrist that limited wrist rotation from 180° to 90° as in primitive primates. To our surprise, we found that a previously unknown primate-specific gene TOSPEAK had been disrupted in the family. TOSPEAK emerged de novo in an ancestor of extant primates across a 540 kb region of the genome with a pre-existing highly conserved long-range laryngeal enhancer for a neighbouring bone morphogenetic protein gene GDF6. We used transgenic mouse modelling to identify two additional GDF6 long-range enhancers within TOSPEAK that regulate GDF6 expression in the wrist. Disruption of TOSPEAK in the affected family blocked the transcription of TOSPEAK across the 3 GDF6 enhancers in association with a reduction in GDF6 expression and retrograde development of the larynx and wrist. Furthermore, we describe how TOSPEAK developed a human-specific promoter through the expansion of a penta-nucleotide direct repeat that first emerged de novo in the promoter of TOSPEAK in gibbon. This repeat subsequently expanded incrementally in higher hominids to form an overlapping series of Sp1/KLF transcription factor consensus binding sites in human that correlated with incremental increases in the promoter strength of TOSPEAK with human having the strongest promoter. Our research indicates a dual evolutionary role for the incremental increases in TOSPEAK transcriptional interference of GDF6 enhancers in the incremental evolutionary development of the wrist and larynx in hominids and the human capacity to speak and their retrogression with the reduction of TOSPEAK transcription in the affected family.

Objectives: The number of revision total knee arthroplasty (TKA) procedures continues to rise, a direct consequence of the increase in primary TKA. The number of arthroplasty-trained orthopaedic surgeons has failed to increase at a corresponding rate, and the increased burden will ultimately fall on non-specialized orthopaedists. Resident involvement in primary TKA has not been found to increase postoperative complications, but revision TKA is more complex and the impact of resident involvement has not been well studied. Methods: Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, this study identified 1834 revision TKA procedures between the years 2008 and 2012. Of these procedures, 863 included resident involvement. Demographic information, comorbidities, operative times, length of stay (LOS), and 30-day postoperative complications were stratified by resident and non-resident involvement and analyzed. Results: Resident involvement was not associated with a significant increase in short-term complications. Operative times were significantly longer with resident involvement (147.50 min with resident involvement vs. 124.55 min without a resident, p < 0.001). Length of stay after procedures with resident involvement was higher by 0.34 days, but this did not reach significance (p = 0.061). Conclusion: Resident involvement in revision total knee arthroplasty was associated with a significant increase in operative time; however, there were no significant increases in postoperative complication rates within 30 days. These findings support continued resident involvement in revision total knee arthroplasty cases and postoperative management.
RESUMO
Objectives: The objective of this commentary is to describe how the deleterious health effects of the competing demands of work and family roles are a public health issue that deserves immediate attention. Study design: This is a commentary article; therefore, there is no study design. Method: I reviewed and summarized existing research on work-family conflict as it relates to public health action. Results: Work-to-family conflict (WFC) is pervasive among US working adults and is higher in the US than in other developed countries. Time, energy, and behaviors invested in fulfilling work responsibilities often compete with fulfilling family responsibilities, with numerous deleterious effects on employee health including sleep, cardiometabolic risk, stress, depression, and anxiety. WFC is a potent source of stress for working Americans, a major contributor to healthcare costs, and a predictor of mortality. US policies have lagged woefully behind the increasing competition between work and family demands. Conclusion: Work-to-family conflict is a public health concern that deserves immediate attention. Until governmental support for adults' work and family lives improves, WFC will continue to be a significant risk factor for public health. Including WFC in public health research and interventions will improve population health and advance health equity.
RESUMO
Background: The type of anesthesia used in total knee arthroplasty is one modifiable factor that could save hospital systems time and money. With spinal and general anesthesia having similar outcomes, more weight can be placed on these anesthesia methods' time or money-saving aspects. Objective: This study aims to determine the differences in time expenditure between spinal and general anesthesia for total knee arthroplasty to optimize OR efficiency and reduce costs. Methods: A retrospective analysis of 200 unilateral total knee arthroplasty procedures (CPT Code 27447) was performed from Jan 2017 - July 2019 at one institution. 100 of these received spinal anesthesia, and 100 received general anesthesia. Patient charts were reviewed to obtain demographic, surgical, and anesthetic data. Results: Time to prepare the patient for surgery and total preoperative time was significantly decreased in the general anesthesia group (24.4 minutes vs. 18.5 minutes; p=<0.0001 and 25.4 minutes vs. 20.4 minutes; p=0.012). After surgery, the time to remove the patient from the operating room was significantly decreased in the spinal group (4.8 minutes vs. 7.0 minutes; p= <0.0001). Nonoperative total time was not significantly different between the two groups (49.3 minutes vs. 46.6 minutes; p=0.1127). Conclusion: While there are significant differences in certain operating room time periods between spinal and general anesthesia, these differences are effectively canceled out when considering total operating room time.
RESUMO
Nongenetic, environmental factors contribute to maternal morbidity and mortality through chemical exposures via air, water, soil, food, and consumer products. Pregnancy represents a particularly sensitive window of susceptibility during which physiological changes to every major organ system increase sensitivity to chemicals that can impact a woman's long-term health. Nonchemical stressors, such as low socioeconomic status, may exacerbate the effects of chemical exposures on maternal health. Racial/ethnic minorities are exposed disproportionately to both chemicals and nonchemical stressors, which likely contribute to the observed health disparities for maternal morbidities and mortality. Epidemiological studies linking exposures to adverse maternal health outcomes underscore the importance of environmental health impacts, and mechanistic studies in model systems reveal how chemicals perturb biological pathways and processes. Environmental stressors are associated with a variety of immediate maternal health impacts, including hypertensive disorders of pregnancy, fibroids, and infertility, as well as long-term maternal health impacts, such as higher risk of breast cancer and metabolic disorders. Identifying and reducing a pregnant woman's environmental exposures is not only beneficial to her offspring but also important to preserve her short- and long-term health.
