RESUMEN

OBJECTIVE: We aimed to assess the risk of developing gestational diabetes mellitus (GDM) in women with a normal A1C (<5.7) compared with those with an A1C in the pre-diabetic range (5.7-6.4). STUDY DESIGN: This study comprises of a retrospective cohort of non-anomalous singleton pregnancies with maternal body mass index (BMI) ≥40 at a single institution from 2013 to 2017. Pregnancies with multiple gestation, late entry to care, type 1 or 2 diabetes, and missing diabetes-screening information were excluded. The primary outcome was development of GDM. Secondary outcomes included fetal growth restriction, macrosomia, gestational age at delivery, large for gestational age, delivery BMI at delivery, total weight gain in pregnancy, induction of labor, shoulder dystocia, and cesarean delivery. Bivariate statistics were used to compare demographics, pregnancy complications, and delivery characteristics of women who had an early A1C < 5.7 and A1C 5.7 to 6.4. Multivariable analyses were used to estimate the odds of the primary outcome. RESULTS: Eighty women (68%) had an early A1C <5.7 and 38 (32%) had a A1C 5.7 to 6.4. Women in the lower A1C group were less likely to be Black (45 vs. 74%, p = 0.01). No differences in other baseline demographics were observed. The median A1C was 5.3 for women with A1C < 5.7 and 5.8 for women with A1C 5.7 to 6.4 (p < 0.001). GDM was significantly more common in women with A1C 5.7 to 6.4 (3.8 vs. 24%, p = 0.002). Women with pre-diabetic range A1C had an odd ratio of 11.1 (95% CI 2.49-48.8) for GDM compared with women with a normal A1C. CONCLUSION: Women with class III obesity and a pre-diabetic range A1C are at an increased risk for gestational diabetes when compared with those with a normal A1C in early pregnancy. KEY POINTS: · One in 3 women with class III obesity had a pre-diabetic range early A1C.. · Class III obese women who have a pre-diabetic A1C have a higher risk of gestational diabetes.. · In this high-risk population, early A1C results in the pre-diabetic range are associated with higher rates of gestational diabetes..

RESUMEN

BACKGROUND: Given the frequency of natural hazards in Haiti, disaster risk reduction is crucial. However, evidence suggests that many people exposed to prior disasters do not engage in disaster preparedness, even when they receive training and have adequate resources. This may be partially explained by a link between mental health symptoms and preparedness; however, these components are typically not integrated in intervention. METHODS: The current study assesses effectiveness of an integrated mental health and disaster preparedness intervention. This group-based model was tested in three earthquake-exposed and flood-prone communities (N = 480), across three time points, using a randomized controlled trial design. The 3-day community-based intervention was culturally-adapted, facilitated by trained Haitian lay mental health workers, and focused on enhancing disaster preparedness, reducing mental health symptoms, and fostering community cohesion. RESULTS: Consistent with hypotheses, the intervention increased disaster preparedness, reduced symptoms associated with depression, post-traumatic stress disorder, anxiety, and functional impairment, and increased peer-based help-giving and help-seeking. Mediation models indicated support for the underlying theoretical model, such that the effect of the intervention on preparedness was mediated by mental health, and that effects on mental health were likewise mediated by preparedness. CONCLUSIONS: The community-based mental health-integrated disaster preparedness intervention is effective in improving mental health and preparedness among community members in Haiti vulnerable to natural hazards. This brief intervention has the potential to be scaled up for use with other communities vulnerable to earthquakes, seasonal flooding, and other natural hazards.

RESUMEN

OBJECTIVE: Excessive gestational weight gain (GWG) increases risk of postpartum weight retention in normal and overweight women but little is known about weight retention in morbidly obese women. We evaluated the impact of GWG on postpartum weight retention in women with class-III obesity. STUDY DESIGN: This is a retrospective cohort of pregnancies at a single institution from July 2013 to December 2017 complicated by body mass index (BMI) ≥ 40 at entry to care. Women were classified as GWG within (WITHIN), less than (LESS), or greater than (MORE) Institute of Medicine's (IOM) recommendations. Women were excluded for multiples, late prenatal care, preterm birth, fetal anomalies, intrauterine demise, weight loss, and missing data. Primary outcome was achievement of intake weight at the postpartum visit. Logistic regression was used to adjust for confounding factors. RESULTS: Among 338 women, 93 (28%) gained WITHIN, 129 (38%) LESS, and 144 (43%) MORE. Women in the MORE group were less likely to achieve their intake weight at the postpartum visit (adjusted odds ratio [AOR] = 0.09 95% confidence interval [CI]: 0.05-0.17, p < 0.01). Women gaining MORE were the only group who did not lose weight from intake to postpartum (Median weight change [LESS: -14 lbs (IQR: -20 to -7)] vs. [WITHIN: -7 lbs (IQR: -13 to -1)] vs. [MORE: 5 lbs (IQR: 0-15)]; p < 0.01). CONCLUSION: Excessive GWG in women with class-III obesity is associated with postpartum weight retention.

RESUMEN

OBJECTIVE: This study aimed to report on Neonatal-Perinatal Medicine (NPM) fellows' views of self-preparedness upon starting postresidency training. STUDY DESIGN: We conducted a national survey of first-year NPM fellows in the United States. The validated survey had five major areas: professionalism, psychomotor ability, independence/graduated responsibility, clinical evaluation, and academia. Survey responses were analyzed using descriptive statistics, and the free-text answers were categorized. RESULTS: Of 228 potential first-year NPM fellows, 140 (61%) initially responded to the survey. Overall, the fellows perceived themselves positively in professionalism and independence/graduated responsibility domains. Marked variability was observed in perceived preparedness in psychomotor ability, with confidence in neonatal intubation and arterial line placement of 86 and 49%, respectively. Lack of confidence in performing neonatal intubation procedures correlates with lack of attempts. The majority (75%) of fellows reported being interested in academia, but less than half felt capable of writing an article. CONCLUSION: First-year NPM fellows identified deficiencies in the domains of psychomotor ability and academia. Residency and fellowship programs should partner to address these deficiencies.

RESUMEN

In Spring/Summer 2020, most individuals living in the United States experienced several months of social distancing and stay-at-home orders because of the coronavirus (COVID-19) pandemic. Clinicians, restaurant cooks, cashiers, transit operators, and other essential workers (EWs), however, continued to work outside the home during this time in order to keep others alive and maintain a functioning society. In the United States, EWs are often low-income persons of color who are more likely to face socioeconomic vulnerabilities, systemic racism, and health inequities. To assess the various impacts of COVID-19 on EWs, an online survey was distributed to a representative sample of individuals residing in six states during May/June 2020. The sample included 990 individuals who identified as EWs and 736 nonessential workers (NWs). We assessed differences between EW and NW respondents according to three categories related to health equity and social determinants of health: (1) demographics (e.g. race/ethnicity); (2) COVID-19 exposure risk pathways (e.g. ability to social distance); and (3) COVID-19 risk perceptions (e.g. perceived risk of contracting COVID-19). EWs were more likely to be Black or Hispanic than NWs and also had lower incomes and education levels on average. Unsurprisingly, EWs were substantially more likely to report working outside the home and less likely to report social distancing and wearing masks indoors as compared to NWs. EWs also perceived a slightly greater risk of contracting COVID-19. These findings, which we discuss in the context of persistent structural inequalities, systemic racism, and health inequities within the United States, highlight ways in which COVID-19 exacerbates existing socioeconomic vulnerabilities faced by EWs.

RESUMEN

Bacteria can form single- and multispecies biofilms exhibiting diverse features based upon the microbial composition of their community and microenvironment. The study of bacterial biofilm development has received great interest in the past 20 years and is motivated by the elegant complexity characteristic of these multicellular communities and their role in infectious diseases. Biofilms can thrive on virtually any surface and can be beneficial or detrimental based upon the community's interplay and the surface. Advances in the understanding of structural and functional variations and the roles that biofilms play in disease and host-pathogen interactions have been addressed through comprehensive literature searches. In this review article, a synopsis of the methodological landscape of biofilm analysis is provided, including an evaluation of the current trends in methodological research. We deem this worthwhile because a keyword-oriented bibliographical search reveals that less than 5% of the biofilm literature is devoted to methodology. In this report, we (i) summarize current methodologies for biofilm characterization, monitoring, and quantification; (ii) discuss advances in the discovery of effective imaging and sensing tools and modalities; (iii) provide an overview of tailored animal models that assess features of biofilm infections; and (iv) make recommendations defining the most appropriate methodological tools for clinical settings.

RESUMEN

Exposure to dust in agricultural and animal environments, known as organic dust, is associated with the development of respiratory symptoms and respiratory diseases. Inflammation is a key feature of lung pathologies associated with organic dust exposure, and exposure to organic dust induces the expression of several immune and inflammatory mediators. However, information on transcription factors and cellular and molecular mechanisms controlling the production of immune and inflammatory mediators induced by organic dust is limited. In this study, we have identified STAT-3 as an important transcription factor controlling the induction of expression of immune and inflammatory mediators by poultry dust extracts in airway epithelial cells and in mouse lungs and delineated the cellular pathway for STAT-3 activation. Poultry dust extract activated STAT-3 phosphorylation in Beas2B and normal human bronchial epithelial cells and in mouse lungs. Chemical inhibition and siRNA knockdown of STAT-3 suppressed induction of immune and inflammatory mediator expression. Antioxidants suppressed the increase of STAT-3 phosphorylation induced by poultry dust extract indicating that oxidative stress [elevated reactive oxygen species (ROS) levels] is important for the activation. Chemical inhibition and siRNA knockdown experiments demonstrated that STAT-3 activation is dependent on the activation of nonreceptor tyrosine-protein kinase 2 (TYK2) and epidermal growth factor receptor (EGFR) tyrosine kinases. Our studies show that poultry dust extract controls the induction of immune and inflammatory mediator expression via a cellular pathway involving oxidative stress-mediated STAT-3 activation by TYK2 and EGFR tyrosine kinases.

RESUMEN

OBJECTIVE: We assessed the risk of small for gestational age and other outcomes in pregnancies complicated by chronic hypertension with blood pressure <140/90 mm Hg. STUDY DESIGN: Retrospective cohort of singletons with hypertension at a single institution from 2000 to 2014. Mean systolic blood pressure and mean diastolic blood pressure were analyzed as continuous and dichotomous variables (<120/80 and 120-139/80-89 mm Hg). The primary outcome was small for gestational age. Secondary outcomes included birth weight, preeclampsia, preterm birth <35 weeks, and a composite of adverse neonatal outcomes. RESULTS: Small for gestational age was not increased with a mean systolic blood pressure <120 mm Hg compared with a mean systolic blood pressure 120 to 129 mm Hg (adjusted odds ratio [AOR] 1.6; 95% confidence interval [CI] 0.92-2.79). Mean diastolic blood pressure <80 mm Hg was associated with a decrease in the risk preeclampsia (AOR 0.57; 95% CI 0.35-0.94), preterm birth <35 weeks (AOR 0.35; 95% CI 0.20-0.62), and the composite neonatal outcome (AOR 0.42; 95% CI 0.22-0.81). CONCLUSION: Mean systolic blood pressure <120 mm Hg and mean diastolic blood pressure <80 mm Hg were not associated with increased risk of small for gestational age when compared with higher, normal mean systolic and diastolic blood pressures.

RESUMEN

OBJECTIVE: To quantify outcomes of infants (<1 year of age) diagnosed with pulmonary vein stenosis (PVS). STUDY DESIGN: MEDLINE (PubMed), Scopus, and Web of Science were searched through February 1, 2017, with no language restrictions. Publications including infants diagnosed with primary PVS, defined as the absence of preceding intervention(s), were considered. The study was performed according to Meta-analysis of Observational Studies in Epidemiology guidelines, the Systematic Reviews, and Meta-Analysis checklist, and registered prospectively. The quality of selected reports was critically examined. Data extraction was independently performed by multiple observers with outcomes agreed upon a priori. Data were pooled using an inverse variance heterogeneity model with incidence of mortality the primary outcome of interest. RESULTS: Forty-eight studies of 185 infants were included. Studies were highly diverse with regards to the participants, interventions, and outcomes reported. The median (range) age at diagnosis was 5.0 (0.1-11.6) months. Pooled mortality was 58.5% (95% CI 49.8%-67.0%, I2 = 21.4%). We observed greater mortality incidence among infants with 3 or 4 vein stenoses than in those with 1 or 2 vein stenoses (83.3% vs 36.1%; P < .01). We observed greater mortality among infants with bilateral than unilateral disease (78.7% vs 26.0%; P < .01). CONCLUSIONS: Studies of primary PVS during infancy are highly variable in their methodological quality and estimates of clinical outcomes; therefore, estimates of prognosis remain uncertain. Multicenter, interdisciplinary collaborations, including alignment of key outcome measurements, are needed to answer questions beyond the scope of available data.

RESUMEN

BACKGROUND: On 25th April 2015, Nepal experienced a 7.8 magnitude earthquake, followed by countless aftershocks. Nearly 9000 people were killed and over 600,000 homes destroyed. Given the high frequency of earthquake and other natural hazards in Nepal, disaster preparedness is crucial. However, evidence suggests that some people exposed to prior disasters do not engage in risk reduction, even when they receive training and have adequate resources. Mental health symptoms, including those associated with prior disaster exposure, may influence engagement in preparedness. Perceived preparedness for future disasters may in turn influence mental health. Social cohesion may influence both mental health and preparedness. METHODS: We developed and tested a hybrid mental health and disaster preparedness intervention in two earthquake-affected communities in Nepal (N = 240), about 2.5 months after the April 25th, 2015 earthquake. The 3-day intervention was culturally adapted, facilitated by trained Nepalese clinicians and focused on enhancing disaster preparedness, mental health, and community cohesion. Communities were selected based on earthquake impacts and matched on demographic variables. The intervention was administered initially to one community, followed by the other receiving the intervention shortly thereafter. Survey data was collected across three time points. Focus groups were also conducted to examine intervention impact. RESULTS: At pre-intervention baseline, greater depression symptoms and lower social cohesion were associated with less disaster preparedness. Depression and PTSD were associated with lower social cohesion. Participation in the intervention increased disaster preparedness, decreased depression- and PTSD-related symptoms, and increased social cohesion. Mediation models indicated that the effect of intervention on depression was partially explained by preparedness. The effect of the intervention on disaster preparedness was partially explained by social cohesion, and the effect of intervention on depression and on PTSD was also partially explained by social cohesion. Data from focus groups illuminate participant perspectives on components of the intervention associated with preparedness, mental health and social cohesion. CONCLUSIONS: This mental health integrated disaster preparedness intervention is effective in enhancing resilience among earthquake-affected communities in Nepal. This brief, cost-effective group intervention has the potential to be scaled up for use with other communities vulnerable to earthquakes and other natural hazards.

RESUMEN

UNLABELLED: Uropathogenic Escherichia coli (UPEC), which causes the majority of urinary tract infections (UTI), uses pilus-mediated adherence to initiate biofilm formation in the urinary tract. Oxygen gradients within E. coli biofilms regulate expression and localization of adhesive type 1 pili. A transposon mutant screen for strains defective in biofilm formation identified the ubiI (formerly visC) aerobic ubiquinone synthase gene as critical for UPEC biofilm formation. In this study, we characterized a nonpolar ubiI deletion mutant and compared its behavior to that of wild-type bacteria grown under aerobic and anoxic conditions. Consistent with its function as an aerobic ubiquinone-8 synthase, deletion of ubiI in UPEC resulted in reduced membrane potential, diminished motility, and reduced expression of chaperone-usher pathway pili. Loss of aerobic respiration was previously shown to negatively impact expression of type 1 pili. To determine whether this reduction in type 1 pili was due to an energy deficit, wild-type UPEC and the ubiI mutant were compared for energy-dependent phenotypes under anoxic conditions, in which quinone synthesis is undertaken by anaerobic quinone synthases. Under anoxic conditions, the two strains exhibited wild-type levels of motility but produced diminished numbers of type 1 pili, suggesting that the reduction of type 1 pilus expression in the absence of oxygen is not due to a cellular energy deficit. Acute- and chronic-infection studies in a mouse model of UTI revealed a significant virulence deficit in the ubiI mutant, indicating that UPEC encounters enough oxygen in the bladder to induce aerobic ubiquinone synthesis during infection. IMPORTANCE: The majority of urinary tract infections are caused by uropathogenic E. coli, a bacterium that can respire in the presence and absence of oxygen. The bladder environment is hypoxic, with oxygen concentrations ranging from 4% to 7%, compared to 21% atmospheric oxygen. This work provides evidence that aerobic ubiquinone synthesis must be engaged during bladder infection, indicating that UPEC bacteria sense and use oxygen as a terminal electron acceptor in the bladder and that this ability drives infection potential despite the fact that UPEC is a facultative anaerobe.

RESUMEN

The intensification and concentration of animal production operations expose workers to high levels of organic dusts in the work environment. Exposure to organic dusts is a risk factor for the development of acute and chronic respiratory symptoms and diseases. Lung epithelium plays important roles in the control of immune and inflammatory responses to environmental agents to maintain lung health. To better understand the effects of organic dust on lung inflammatory responses, we characterized the gene expression profiles of A549 alveolar and Beas2B bronchial epithelial and THP-1 monocytic cells influenced by exposure to poultry dust extract by DNA microarray analysis using Illumina Human HT-12 v4 Expression BeadChip. We found that A549 alveolar and Beas2B bronchial epithelial and THP-1 cells responded with unique changes in the gene expression profiles with regulation of genes encoding inflammatory cytokines, chemokines, and other inflammatory proteins being common to all the three cells. Significantly induced genes included IL-8, IL-6, IL-1ß, ICAM-1, CCL2, CCL5, TLR4, and PTGS2. Validation by real-time qRT-PCR, ELISA, Western immunoblotting, and immunohistochemical staining of lung sections from mice exposed to dust extract validated DNA microarray results. Pathway analysis indicated that dust extract induced changes in gene expression influenced functions related to cellular growth and proliferation, cell death and survival, and cellular development. These data show that a broad range of inflammatory mediators produced in response to poultry dust exposure can modulate lung immune and inflammatory responses. This is the first report on organic dust induced changes in expression profiles in lung epithelial and THP-1 monocytic cells.

RESUMEN

BACKGROUND: Natural hazards are increasing in frequency and intensity due to climate change. Many of these natural disasters cannot be prevented; what may be reduced is the extent of the risk and negative impact on people and property. Research indicates that the 2019-2020 bushfires in Australia (also known as the "Black Summer Bushfires") resulted in significant psychological distress among Australians both directly and indirectly exposed to the fires. Previous intervention research suggests that communities impacted by natural hazards (eg, earthquakes, hurricanes, and floods) can benefit from interventions that integrate mental health and social support components within disaster preparedness frameworks. Research suggests that disaster-affected communities often prefer the support of community leaders, local services, and preexisting relationships over external supports, highlighting that community-based interventions, where knowledge stays within the local community, are highly beneficial. The Community-Based Disaster Mental Health Intervention (CBDMHI) is an evidence-based approach that aims to increase disaster preparedness, resilience, social cohesion, and social support (disaster-related help-seeking), and decrease mental health symptoms, such as depression and anxiety. OBJECTIVE: This research aims to gain insight into rural Australian's recovery needs post natural hazards, and to enhance community resilience in advance of future fires. Specifically, this research aims to adapt the CBDMHI for the rural Australian context and for bushfires and second, to assess the acceptability and feasibility of the adapted CBDMHI in a rural Australian community. METHODS: Phase 1 consists of qualitative interviews (individual or dyads) with members of the target bushfire-affected rural community. Analysis of these data will include identifying themes related to disaster preparedness, social cohesion, and mental health, which will inform the adaptation. An initial consultation phase is a key component of the adaptation process and, therefore, phase 2 will involve additional discussion with key stakeholders and members of the community to further guide adaptation of the CBDMHI to specific community needs, building on phase 1 inputs. Phase 3 includes identifying and training local community leaders in the adapted intervention. Following this, leaders will co-deliver the intervention. The acceptability and feasibility of the adapted CBDMHI within the community will be evaluated by questionnaires and semistructured interviews. Effectiveness will be evaluated by quantifying psychological distress, resilience, community cohesion, psychological preparedness, and help-seeking intentions. RESULTS: This study has received institutional review board approval and commenced phase 1 recruitment in October 2022. CONCLUSIONS: The study will identify if the adapted CBDMHI is viable and acceptable within a village in the Northern Tablelands of New South Wales, Australia. These findings will inform future scale-up in the broader rural Australian context. If this intervention is well received, the CBDMHI may be valuable for future disaster recovery and preparedness efforts in rural Australia. These findings may inform future scale-up in the broader rural Australian context. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/53454.

RESUMEN

Background and Aims: There is a need for high utility and portability, and cost-effective technologies that are suitable for assessing dual-task gait after experiencing a concussion. Current technologies utilized such as 3D motion capture and force plates are too complex and expensive for most practitioners. The aim of this study was to quantify the variability of dual-task walking gait parameters using in-shoe inertial sensors in nonconcussed individuals. Methods: This was a randomized within-subject repeated measures design conducted within a sports laboratory. Twenty healthy, uninjured, nonconcussed participants were recruited for this study. Gait variables of interest were measured across three 2-min continuous walking protocols (12 m, 30 m, 1 min out and back) while performing a cognitive task of counting backward in sevens from a randomly generated number between 300 and 500. Testing was completed over three occasions separated by 7 days, for a total of nine walking trials. Participants completed the testing protocols in a randomized, individual order. The primary outcome was to determine the variability of dual-task walking gait parameters using in-shoe inertial sensors in nonconcussed individuals across three protocols. Results: Three to four participants were allocated to each randomized protocol order. Regarding the absolute consistency (coefficient of variation [CV]) between testing occasions, no gait measure was found to have variability above 6.5%. Relative consistency (intraclass correlation coefficient [ICC]) was acceptable (>0.70) in 95% of the variables of interest, with only three variables < 0.70. Similar variability was found across the three testing protocols. Conclusion: In-shoe inertial sensors provide a viable option for monitoring gait parameters. This technology is also reliable across different testing distances, thus offering various testing options for practitioners. Further research needs to be conducted to examine the variability with concussed subjects.

RESUMEN

OBJECTIVE: To understand the methodological approaches taken by various research groups and determine the kinematic variables that could consistently and reliably differentiate between concussed and non-concussed individuals. METHODS: MEDLINE via PubMed, CINAHL Complete via EBSCO, EBSCOhost, SPORTDiscus, and Scopus were searched from inception until 31 December 2021, using key terms related to concussion, mild traumatic brain injury, gait, cognition and dual task. Studies that reported spatiotemporal kinematic outcomes were included. Data were extracted using a customised spreadsheet, including detailed information on participant characteristics, assessment protocols, equipment used, and outcomes. RESULTS: Twenty-three studies involving 1030 participants met the inclusion criteria. Ten outcome measures were reported across these articles. Some metrics such as gait velocity and stride length may be promising but are limited by the status of the current research; the majority of the reported variables were not sensitive enough across technologies to consistently differentiate between concussed and non-concussed individuals. Understanding variable sensitivity was made more difficult given the absence of any reporting of reliability of the protocols and variables in the respective studies. CONCLUSION: Given the current status of the literature and the methodologies reviewed, there would seem little consensus on which gait parameters are best to determine return to play readiness after concussion. There is potential in this area for such technologies and protocols to be utilised as a tool for identifying and monitoring concussion; however, improving understanding of the variability and validity of technologies and protocols underpins the suggested directions of future research. Inertial measurement units appear to be the most promising technology in this aspect and should guide the focus of future research. IMPACT: Results of this study may have an impact on what technology is chosen and may be utilised to assist with concussion diagnosis and return to play protocols.

RESUMEN

BACKGROUND: Understanding factors that influence information seeking, assessment of risk and mitigation behaviors is critical during a public health crises. This longitudinal study examined the influence of self-reported mental health during the early months of the COVID-19 pandemic on information seeking, risk perception and perceived mask wearing ability. Mental health screener items included fear, anger, and hopelessness in addition to avoidance, diminished functional ability and global distress. Theoretical models inform hypotheses linking mental health items and outcomes. METHODS: The research employed a longitudinal 6-state 3-wave online panel survey, with an initial sample of 3,059 participants (2,232 included in longitudinal analyses). Participants roughly represented the states' age, race, ethnicity, and income demographics. RESULTS: Women, those who identified as Hispanic/Latinx, Black Americans and lower income participants reported higher overall rates of distress than others. Information seeking was more common among older persons, Democrats, retirees, those with higher education, and those who knew people who had died of COVID-19. Controlling for such demographic variables, in multivariable longitudinal models that included baseline mental health measures, distress and fear were associated with increased information seeking. Distress and fear were also associated with increased risk perception, and feelings of hopelessness were associated with lower reported mask-wearing ability. CONCLUSIONS: Results advance understanding of the role mental health can play in information seeking, risk perception and mask wearing with implications for clinicians, public health practitioners and policy makers.

RESUMEN

BACKGROUND: Because obese women are at increased risk for insulin resistance and development gestational diabetes (GDM), the American College of Obstetricians and Gynecologists (ACOG) recommends early GDM screening in this population. For obese women with a normal early 1-hour 50 g oral glucose challenge test (eGCT), the risk of developing GDM later in the pregnancy is unknown. Thus, we aimed to assess the risk of developing gestational diabetes based on the value of a normal eGCT. STUDY DESIGN: Retrospective cohort of non-anomalous singleton pregnancies with maternal body mass index (BMI) ≥40 at the time of entry to prenatal care at a single institution from 2013 to 2017. Pregnancies with abnormal early 1-hour 50 g glucose challenge test (eGCT), multiple gestation, late entry to care, type 1 or 2 diabetes, and missing diabetes-screening information are excluded. Primary outcome was development of GDM. Secondary outcomes include fetal growth restriction, macrosomia, gestational age at delivery, large for gestational age, delivery BMI, total weight gain in pregnancy, induction of labor, shoulder dystocia, and cesarean delivery. Bivariate statistics compare demographics, pregnancy complications and delivery characteristics of women who had an eGCT≤ 100 mg/dL (low-normal eGCT) and women who had an eGCT of 101-134 mg/dL (high-normal eGCT). Regression models used to estimate odds of primary outcome. RESULTS: Of 169 women, 66(39%) had a low-normal eGCT, and 103(61%) had a high-normal eGCT. Women in the low-normal eGCT group were more likely to use recreational drugs (p = 0.03), other baseline demographics did not differ. The rate of GDM was low in this population (5.3%), with no difference in the rate of GDM between with a low-normal eGCT (1.5%) and high-normal eGCT (7.7%) (p = 0.09). The median neonatal birthweight was higher in the high-normal GCT group (3405 g) as compared to the low-no GCT (3285 g) (p = 0.03). CONCLUSIONS: Among women with class 3 obesity, the specific value of an early normal GCT was not associated with developing gestational diabetes mellitus later in the pregnancy. Larger studies are needed confirm these findings.

RESUMEN

BACKGROUND: Maternal obesity is associated with delayed lactogenesis and shorter duration of breastfeeding compared to patients with a normal BMI. RESEARCH AIM/QUESTION: We investigated the impact of excessive gestational weight gain, defined as greater than the Institute of Medicine guidelines (>9.1 kg), on the initiation and duration of breastfeeding in patients with class III obesity. METHODS: Retrospective cohort of patients with body mass index ≥40 in first trimester, delivering a singleton term infant at a tertiary care center between July 2013 and December 2017. Primary outcome was exclusive breastfeeding at discharge and at postpartum visit. Secondary outcomes included any breastfeeding at discharge and postpartum visit, and cessation of breastfeeding by the postpartum visit. Descriptive statistics were used to compare those whose gestational weight gain exceeded (eIOM) versus met (mIOM) Institute of Medicine guidelines. Regression models were performed to adjust for baseline confounding factors. RESULTS: Of 294 women included, 117(39.8%) were in the eIOM group. These women were more likely to be primigravida, have a higher delivery BMI, greater delivery blood loss, and have a neonate admitted to the intensive care unit. Exclusive breastfeeding at discharge was not different between eIOM and mIOM (66.7% vs 70.9%, p = .44), nor did eIOM impact likelihood of exclusive breastfeeding at postpartum visit (40.1% vs 34.2%, p = .31). When controlling for confounding factors, breastfeeding at discharge (aOR 1.54 95% CI [0.68-3.49]) or postpartum visit (aOR 0.67[0.31-1.47]) did not differ between eIOM compared to mIOM. CONCLUSIONS: Among women with class III obesity, excessive gestational weight gain did not impact the rate of exclusive breastfeeding at discharge or postpartum visit.

RESUMEN

OBJECTIVE: This study evaluated the influence of early gestational weight gain (GWG) on neonatal outcomes among women with class III obesity. STUDY DESIGN: Retrospective cohort of women with class III obesity who gained more than the Institute of Medicine (IOM) guidelines (>20lbs). Women gaining ≥75% of total gestational weight prior to 28 weeks (EWG) were compared to women gaining <75% of their total weight prior to 28 weeks (SWG). The primary outcome was a neonatal composite morbidity and mortality. Secondary outcomes included individual components of composite and LGA. RESULTS: Of 144 women identified, 42 (29.2%) had EWG and 102 (70.8%) had SWG. Though 11% of the total population had composite neonatal morbidity, this did not differ between groups (p = .4). LGA was nearly twice as common in the SWG group (41% vs 26%, p = .13). EWG was associated with decreased risk of LGA (AOR 0.25 95% CI 0.08, 0.78) and lower median birth weight (AOR -312 g 95% CI -534.7, -90.2). CONCLUSION: Though adverse neonatal outcomes were common in this population, timing of gestational weight gain was not correlated. Increased rates of LGA and higher median birth weight in the SWG group suggests excessive GWG continuing in the third trimester of pregnancy may be of import for neonatal size.

RESUMEN

OBJECTIVE: To assess the implementation of an antihypertensive pathway order set to improve treatment of severe hypertension in pregnancy and the postpartum period in the inpatient setting. STUDY DESIGN: A multi-disciplinary task force created a hypertensive pathway order set and provided staff training. The order set allowed providers to initiate a treatment algorithm, which then gave nurses guidelines to recheck blood pressures and progressively increase short-acting antihypertensive dosage if needed. Pregnant and postpartum patients documented to have ≥2 consecutive severe range blood pressures in the year prior (2017) and the year after (2019) implementation of the pathway were included. Primary outcomes included whether any antihypertensive was given, whether it was given for all instances of severe hypertension, and time to antihypertensive administration. RESULTS: A total of 566 patients with severe hypertension were included-304 in the pre-implementation year and 262 in the post-implementation year. Significantly more patients received an antihypertensive at least once (67 % versus 80 %, p < 0.01) and for all instances of severe hypertension (29 % versus 47 %, p < 0.01) in the post-intervention cohort. There was a significant improvement in time to antihypertensive administration (24 versus 10 min, p < 0.01). CONCLUSION: This study evaluates the efficacy of an antihypertensive intervention in the Southeast United States, which is particularly significant given the region's higher rates of hypertension and hypertension-related mortality. This study provides confirmatory evidence that implementation of a standardized order set along with measuring compliance and staff education is associated with improved treatment rates and time to treatment administration.
