Recent Immigrants With Inflammatory Bowel Disease Have Significant Healthcare Utilization From Preconception to Postpartum: A Population Cohort Study.

INTRODUCTION: Immigrants with inflammatory bowel disease (IBD) may have increased healthcare utilization during pregnancy compared with non-immigrants, although this remains to be confirmed. We aimed to characterize this between these groups. METHODS: We accessed administrative databases to identify women (aged 18-55 years) with IBD with a singleton pregnancy between 2003 and 2018. Immigration status was defined as recent (<5 years of the date of conception), remote (≥5 years since the date of conception), and none. Differences in ambulatory, emergency department, hospitalization, endoscopic, and prenatal visits during 12 months preconception, pregnancy, and 12 months postpartum were characterized. Region of immigration origin was ascertained. Multivariable negative binomial regression was performed for adjusted incidence rate ratios (aIRRs) with 95% confidence intervals (CIs). RESULTS: A total of 8,880 pregnancies were included, 8,304 in non-immigrants, 96 in recent immigrants, 480 in remote immigrants. Compared with non-immigrants, recent immigrants had the highest rates of IBD-specific ambulatory visits during preconception (aIRR 3.06, 95% CI 1.93-4.85), pregnancy (aIRR 2.15, 95% CI 1.35-3.42), and postpartum (aIRR 2.21, 1.37-3.57) and the highest rates of endoscopy visits during preconception (aIRR 2.69, 95% CI 1.64-4.41) and postpartum (aIRR 2.01, 95% CI 1.09-3.70). There were no differences in emergency department and hospitalization visits between groups, although those arriving from the Americas were the most likely to be hospitalized for any reason. All immigrants with IBD were less likely to have a first trimester prenatal visit. DISCUSSION: Recent immigrants were more likely to have IBD-specific ambulatory care but less likely to receive adequate prenatal care during pregnancy.

Risk of Cesarean Delivery Among People With Inflammatory Bowel Disease According to Disease Characteristics: A Population-Based Study.

OBJECTIVES: It is unclear if use of cesarean delivery in people with inflammatory bowel disease (IBD) is guideline-concordant. We compared the odds of cesarean delivery among primiparous individuals with IBD versus without, overall, and by disease characteristics, as well as time to subsequent delivery. METHODS: Retrospective matched population-based cohort study between 1 April 1994 and 31 March 2020. Primiparous individuals aged 15-55 years with IBD were matched to those without IBD on age, year, hospital, and number of newborns delivered. Primary outcome was cesarean delivery versus vaginal delivery. Multivariable conditional logistic regression analyses were performed to estimate the odds of cesarean delivery among individuals with and without IBD as a binary exposure, and a categorical exposure based on IBD-related indications for cesarean delivery. Time to subsequent delivery was evaluated using a Cox proportional hazard model. RESULTS: We matched 7472 individuals with IBD to 37 360 individuals without (99.02% match rate). Individuals with IBD were categorised as having perianal (PA) disease (IBD-PA, n = 764, 10.2%), prior ileal pouch-anal anastomosis (n = 212, 2.8%), or IBD-Other (n = 6496, 86.9%). Cesarean delivery rates were 35.4% in the IBD group versus 30.4% in their controls (adjusted odds ratio 1.27; 95% CI 1.20-1.34). IBD-ileal pouch-anal anastomosis had a cesarean delivery rate of 66.5%, compared to 49.9% in IBD-PA and 32.7% in IBD-Other. There was no significant difference in the rate of subsequent delivery in those with and without IBD (adjusted hazard ratio 1.03; 95% CI 1-1.07). CONCLUSIONS: The higher risk of cesarean delivery in people with IBD reflects guideline-concordant use. Individuals with and without IBD were equally likely to have a subsequent delivery with similar timing.

A role for triglyceride lipase brummer in the regulation of sex differences in Drosophila fat storage and breakdown.

Triglycerides are the major form of stored fat in all animals. One important determinant of whole-body fat storage is whether an animal is male or female. Here, we use Drosophila, an established model for studies on triglyceride metabolism, to gain insight into the genes and physiological mechanisms that contribute to sex differences in fat storage. Our analysis of triglyceride storage and breakdown in both sexes identified a role for triglyceride lipase brummer (bmm) in the regulation of sex differences in triglyceride homeostasis. Normally, male flies have higher levels of bmm mRNA both under normal culture conditions and in response to starvation, a lipolytic stimulus. We find that loss of bmm largely eliminates the sex difference in triglyceride storage and abolishes the sex difference in triglyceride breakdown via strongly male-biased effects. Although we show that bmm function in the fat body affects whole-body triglyceride levels in both sexes, in males, we identify an additional role for bmm function in the somatic cells of the gonad and in neurons in the regulation of whole-body triglyceride homeostasis. Furthermore, we demonstrate that lipid droplets are normally present in both the somatic cells of the male gonad and in neurons, revealing a previously unrecognized role for bmm function, and possibly lipid droplets, in these cell types in the regulation of whole-body triglyceride homeostasis. Taken together, our data reveal a role for bmm function in the somatic cells of the gonad and in neurons in the regulation of male-female differences in fat storage and breakdown and identify bmm as a link between the regulation of triglyceride homeostasis and biological sex.

The COVID-19 Pandemic Significantly Impacts Pregnancy Planning and Mental Health of Women With Inflammatory Bowel Disease.

BACKGROUND AND GOALS: The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted daily life, particularly in those with inflammatory bowel disease (IBD). We aimed to determine the impact of the pandemic on the pregnancy planning and mental health of women with IBD. METHODS: Women with IBD (age 18 to 45 y) were asked to complete anonymous surveys on the impact of the COVID-19 pandemic on pregnancy planning and mental health symptoms such as stress (Perceived Stress Scale), depression (Patient Health Questionnaire-9), and anxiety (Generalized Anxiety Disorder-7). Univariate and multivariable analyses were conducted to identify risk factors associated with stress, depression, and anxiety during the pandemic. RESULTS: Seventy-three women with IBD were included (mean age: 32.1). Of 39 patients who were preconception, 20 (51.3%) reported a significant impact of the pandemic on pregnancy planning, with common reasons for not planning conception being fear of transmission of the virus to the fetus, lack of social supports, and no desire to be in hospital during pregnancy. Over half of all women reported an increase in stress and depression symptoms during the pandemic, with over half also reporting symptoms of anxiety. On multivariable linear regression analyses, increased anxiety levels were a significant predictor of increased stress and depression symptoms during the pandemic. Urban residence and younger age were significant predictors of increased anxiety symptoms during the pandemic. CONCLUSION: A significant proportion of women with IBD experienced an impact of the COVID-19 pandemic on pregnancy planning and mental health illnesses such as stress, depression, and anxiety.

Impact of Disease Activity and Inflammatory Bowel Disease Subtype on Quality of Life in Preconception and Pregnant Patients.

BACKGROUND: Inflammatory bowel disease (IBD) and pregnancy both impact health-related quality of life (HRQoL). However, little is known about IBD-related HRQoL around pregnancy. AIMS: To assess the trajectory and predictors of HRQoL in preconception and pregnant patients with Crohn's disease (CD) and ulcerative colitis (UC). METHODS: Preconception and pregnant patients with IBD were followed prospectively from preconception to twelve months postpartum at a tertiary referral centre. Participants completed the Short IBD Questionnaire (SIBDQ) and were assessed for clinical disease activity (modified Harvey Bradshaw Index or partial Mayo score) and objective disease activity (C-reactive protein [CRP], fecal calprotectin [FCP]). RESULTS: A total of 61 patients with IBD (25 CD, 36 UC) were included. During preconception, patients with UC had higher SIBDQ bowel and social sub-scores than those with CD, but this reversed during postpartum. Patients with CD but not UC developed a significant, sustained improvement in SIBDQ upon becoming pregnant, which persisted into 12 months postpartum. In a multivariable linear regression model, clinical disease activity negatively predicted SIBDQ at every pregnancy timepoint and up to 12 months postpartum. SIBDQ was significantly lower in patients with CRP ≥ 8.0 mg/L during trimester 1 (T1), but not later in pregnancy. SIBDQ bowel sub-scores were significantly lower in patients with FCP ≥ 250 mg/kg at T2, T3, and 6 months postpartum. CONCLUSIONS: Clinical disease activity is a consistent negative predictor of HRQoL from conception to 12 months postpartum. Patients with UC experience better preconception HRQoL but suffer worse postpartum HRQoL than those with CD.

Ocular Monkeypox - United States, July-September 2022.

As of October 11, 2022, a total of 26,577 monkeypox cases had been reported in the United States.* Although most cases of monkeypox are self-limited, lesions that involve anatomically vulnerable sites can cause complications. Ocular monkeypox can occur when Monkeypox virus (MPXV) is introduced into the eye (e.g., from autoinoculation), potentially causing conjunctivitis, blepharitis, keratitis, and loss of vision (1). This report describes five patients who acquired ocular monkeypox during July-September 2022. All patients received treatment with tecovirimat (Tpoxx)†; four also received topical trifluridine (Viroptic).§ Two patients had HIV-associated immunocompromise and experienced delays between clinical presentation with monkeypox and initiation of monkeypox-directed treatment. Four patients were hospitalized, and one experienced marked vision impairment. To decrease the risk for autoinoculation, persons with monkeypox should be advised to practice hand hygiene and to avoid touching their eyes, which includes refraining from using contact lenses (2). Health care providers and public health practitioners should be aware that ocular monkeypox, although rare, is a sight-threatening condition. Patients with signs and symptoms compatible with ocular monkeypox should be considered for urgent ophthalmologic evaluation and initiation of monkeypox-directed treatment. Public health officials should be promptly notified of cases of ocular monkeypox. Increased clinician awareness of ocular monkeypox and of approaches to prevention, diagnosis, and treatment might reduce associated morbidity.

Distinct sleep disturbance and cognitive dysfunction profiles in oncology outpatients receiving chemotherapy.

PURPOSE: Sleep disturbance and cancer-related cognitive impairment (CRCI) are two of the most common symptoms reported by patients undergoing chemotherapy. Less is known about how these symptoms co-occur and their associated risk factors. Study purposes were to identify subgroups of patients with distinct sleep disturbance and CRCI profiles and evaluate for differences among the subgroups in demographic and clinical characteristics, symptom severity scores, and QOL outcomes. METHODS: A total of 1,333 oncology outpatients receiving chemotherapy completed self-report questionnaires on sleep disturbance and cognitive dysfunction six times over two cycles of chemotherapy. Latent profile analysis was used to identify distinct sleep disturbance AND cognitive dysfunction profiles. Parametric and non-parametric tests were used to evaluate for differences among the classes. RESULTS: Two distinct profiles were identified (i.e., Low = low levels of both sleep disturbance and cognitive dysfunction (53.5%); High = high levels of both sleep disturbance and cognitive dysfunction (45.5%)). Patients in the High class were younger, more likely to be female, had a lower functional status and a higher level of comorbidity. In addition, these patients had a higher symptom burden and a lower quality of life. CONCLUSION: Almost half of the patients undergoing chemotherapy experienced clinically meaningful levels of both symptoms. Of note, sleep disturbance is frequently overlooked by both clinicians and patients. Clinicians need to recommend cognitive rehabilitation and physical activity programs to decrease patients' symptom burden.

A Dedicated Pregnancy Clinic Improves Reproductive Knowledge in Inflammatory Bowel Disease.

BACKGROUND AND AIMS: Factors affecting pregnancy-related knowledge in women with inflammatory bowel disease (IBD) remain unknown. We aimed to determine these factors and to assess the impact of a dedicated pregnancy clinic on improving knowledge in women with IBD. METHODS: Adult women with IBD attending the pregnancy IBD clinic at the University of Alberta from 2014 to 2018 were enrolled. Each patient completed the Crohn's and Colitis Pregnancy Knowledge (CCPKnow) questionnaire at baseline and after individualized education delivered at each clinic visit. Knowledge levels were defined as very good if CCPKnow scores ≥ 14. Mean CCPKnow scores were reported with standard deviations (SD) and compared using the paired T test. RESULTS: The mean CCPKnow score in 117 patients at baseline was 9.65 (SD 4.18). Compared to those with disease duration < 5 years, those with disease duration > 5 years had higher rates of very good baseline knowledge (3.0% vs. 26.4%, p = 0.036). Similarly, those on preconception IBD-related therapy were more likely to have very good knowledge compared to those on no therapy (22.5% vs. 0%, p = 0.024). Fifty-one patients completed a post-clinic CCPKnow survey with a mean CCPKnow of 10.72 (SD 4.32). Participation in a pregnancy clinic improved reproductive knowledge in those with ulcerative colitis (p = 0.001), disease duration > 5 years (p = 0.017), those with at least a university education (p = 0.014) and those on IBD-related therapies (p = 0.026). CONCLUSIONS: Increased disease duration and preconception IBD-related therapy may be associated with increased pregnancy-related knowledge. A dedicated pregnancy clinic can improve reproductive knowledge in women with IBD.

Post-neonatal Outcomes of Infants Born to Women with Active Trimester One Inflammatory Bowel Disease: A Pilot Study.

BACKGROUND: Ulcerative colitis (UC) and Crohn's disease (CD) are chronic inflammatory bowel diseases (IBD) that affect women in their childbearing years. Early pregnancy flare-up negatively impacts obstetrical and perinatal outcomes, but the impact on infants is unclear. AIM: To determine whether active IBD disease activity is associated with adverse post-neonatal outcomes post-partum. METHODS: This is a single-center cohort study of women with IBD who underwent serial monitoring of post-neonatal outcomes post-partum. Infant outcomes were collected via self-filled questionnaires, including perinatal outcomes, APGAR scores, infant weights, heights, feeding habits and comorbidities within the first year of life. RESULTS: There was a total of 98 women with IBD and 78 live births throughout the study: 50 women were enrolled during trimester one alone and 49 were included into the current study. Among the 49 analyzed, 32 were in remission and 17 were in relapse during trimester one. Trimester one disease activity was associated with more adverse obstetrical outcomes including emergency C-sections and reduced 1-min APGAR scores. At follow-up, infants born to women with T1-flare had reduced weight-for-age Z scores and length-for-age Z scores up to 6 months of age. CONCLUSIONS: Active IBD during trimester one is correlated with adverse post-neonatal outcomes, particularly decreased infant weight and height up to 6 months of age. This suggests disease control in first trimester is essential for optimizing infant growth and post-neonatal outcomes.

A Novel Decision Aid Improves Quality of Reproductive Decision-Making and Pregnancy Knowledge for Women with Inflammatory Bowel Disease.

BACKGROUND: Women with inflammatory bowel disease (IBD) with poor IBD-specific reproductive knowledge experience more childlessness and fear of IBD medications in pregnancy. The Pregnancy in IBD Decision Aid (PIDA), developed by an international multidisciplinary team, offers personalized online decision support regarding pregnancy in IBD. AIMS: Assess the impact of PIDA on quality of reproductive decision-making and pregnancy-related knowledge among preconception (PC) and pregnant patients with IBD, and evaluate acceptability to patients and clinicians. METHODS: PC and pregnant patients with IBD aged 18-45 completed questionnaires pre- and post-PIDA to assess quality of decision-making (Decisional Conflict Scale (DCS); Decision Self-Efficacy Scale (DSES) and IBD-in-pregnancy knowledge (Crohn's and Colitis Pregnancy Knowledge Score (CCPKnow)). Paired t test assessed for differences pre- and post-PIDA. Patients and clinicians completed acceptability surveys. RESULTS: DCS and DSES were completed by 74 patients (42 Crohn's disease, 32 ulcerative colitis); 41 PC and 33 pregnant. DCS improved significantly post-PIDA in PC patients regarding pregnancy planning (t(40) = 4.83, p < 0.0001, Cohen's dz = 0.75) and in pregnant patients regarding medication management (t(32) = 2.37, p = 0.0242, dz = 0.41). DSES for PC patients improved significantly post-PIDA (t(40) = -3.56, p = 0.001, dz = -0.56). CCPKnow improved significantly post-PIDA in PC (t(42) = 4.93, p < 0.0001, dz = -0.75) and pregnant patients (t(32) = 5.1, p < 0.0001, dz = -0.89). PIDA was deemed optimal for length, readability, and content amount and considered highly useful by patients (n = 73) and clinicians (n = 14). CONCLUSIONS: Patients using PIDA developed an improved quality of reproductive decision-making and IBD-in-pregnancy knowledge. PIDA is an accessible tool that can empower women with IBD to make values-congruent, evidence-based decisions regarding pregnancy and may reduce voluntary childlessness.

Elevated IL-6 and IL-22 in Early Pregnancy Are Associated with Worse Disease Course in Women with Inflammatory Bowel Disease.

Inflammatory bowel diseases (IBD), including Ulcerative Colitis (UC) and Crohn's disease (CD), are inflammatory conditions of the intestinal tract that affect women in their reproductive years. Pregnancy affects Th1- and Th2-cytokines, but how these changes occur during pregnancy in IBD is unclear. We performed a longitudinal profiling of serum cytokines in a cohort of 11 healthy pregnant women and 76 pregnant women with IBD from the first trimester of pregnancy to the first 12 months post-partum. Participants were monitored for biochemical disease activity (C-reactive protein [CRP] and fecal calprotectin [FCP]) and clinical activities. Maternal cytokines were measured using ELISA. We identified changes in Th1 and Th17 cytokines throughout pregnancy in healthy pregnant women. During pregnancy, maternal serum cytokine expressions were influenced by IBD, disease activity, and medications. Active UC was associated with an elevation in IL-21, whereas active CD was associated with elevated IFN-γ, IL-6, and IL-21. Interestingly, T1 serum cytokine levels of IL-22 (>0.624 pg/mL) and IL-6 (>0.648 pg/mL) were associated with worse IBD disease activity throughout pregnancy in women with UC and CD, respectively. This shows serum cytokines in pregnancy differ by IBD, disease activity, and medications. We show for the first time that T1 IL-22 and IL-6 correlate with IBD disease course throughout pregnancy.

Shared decision making in pregnancy in inflammatory bowel disease: design of a patient orientated decision aid.

BACKGROUND: Research has indicated a lack of disease-specific reproductive knowledge among patients with Inflammatory Bowel Disease (IBD) and this has been associated with increased "voluntary childlessness". Furthermore, a lack of knowledge may contribute to inappropriate medication changes during or after pregnancy. Decision aids have been shown to support decision making in pregnancy as well as in multiple other chronic diseases. A published decision aid for pregnancy in IBD has not been identified, despite the benefit of pre-conception counselling and patient desire for a decision support tool. This study aimed to develop and test the feasibility of a decision aid encompassing reproductive decisions in the setting of IBD. METHODS: The International Patient Decision Aid Standards were implemented in the development of the Pregnancy in IBD Decision Aid (PIDA). A multi-disciplinary steering committee was formed. Patient and clinician focus groups were conducted to explore themes of importance in the reproductive decision-making processes in IBD. A PIDA prototype was designed; patient interviews were conducted to obtain further insight into patient perspectives and to test the prototype for feasibility. RESULTS: Issues considered of importance to patients and clinicians encountering decisions regarding pregnancy in the setting of IBD included fertility, conception timing, inheritance, medications, infant health, impact of surgery, contraception, nutrition and breastfeeding. Emphasis was placed on the provision of preconception counselling early in the disease course. Decisions relating to conception and medications were chosen as the current focus of PIDA, however content inclusion was broad to support use across preconception, pregnancy and post-partum phases. Favourable and constructive user feedback was received. CONCLUSIONS: The novel development of a decision aid for use in pregnancy and IBD was supported by initial user testing.

Fecal Calprotectin May Predict Adverse Pregnancy-Related Outcomes in Patients with Inflammatory Bowel Disease.

BACKGROUND: The role of fecal calprotectin in predicting pregnancy-related outcomes in inflammatory bowel disease (IBD) remains unknown. AIM: To determine whether increased fecal calprotectin during pregnancy is associated with adverse pregnancy outcomes in IBD. METHODS: This is a multicenter cohort study of women with IBD who underwent fecal calprotectin monitoring during pregnancy. Fecal calprotectin levels were stratified by trimester, and adverse pregnancy-related outcomes were recorded. The Mann-Whitney U test assessed differences between continuous variables, whereas categorical variables were compared using the Chi-squared test. RESULTS: Eighty-five women with IBD were included. First trimester fecal calprotectin was higher in patients who underwent emergency Cesarean birth compared to those who had a vaginal delivery (503 ug/g, IQR 1554.3 ug/g vs. 130 ug/g, IQR 482 ug/g, p = .030, respectively) and in those who delivered infants with low birth weight compared to normal birth weight (1511 ug/g, IQR 579 ug/g vs. 168 ug/g, IQR 413 ug/g, p = .049, respectively). Third trimester fecal calprotectin was higher in those with non-elective induction of labor (334.5 ug/g, IQR 1411.0 ug/g) compared to those with spontaneous delivery (116.5 ug/g, IQR 227.1 ug/g) (p = .025). Those with a fecal calprotectin ≥ 250 ug/g in the second trimester had an increased incidence of infants with low birth weight (35.3% vs. 3.8%) (p = .049), whereas those with a fecal calprotectin ≥ 250 ug/g in the third trimester had an increased incidence of non-elective induction of labor (43.8% vs. 10.3%, p = .030). CONCLUSIONS: Fecal calprotectin may be a useful noninvasive marker to predict adverse pregnancy-related outcomes in patients with IBD.

CD71+ Erythroid Suppressor Cells Promote Fetomaternal Tolerance through Arginase-2 and PDL-1.

Survival of the allogeneic pregnancy depends on the maintenance of immune tolerance to paternal alloantigens at the fetomaternal interface. Multiple localized mechanisms contribute to the fetal evasion from the mother's immune rejection as the fetus is exposed to a wide range of stimulatory substances such as maternal alloantigens, microbes and amniotic fluids. In this article, we demonstrate that CD71+ erythroid cells are expanded at the fetomaternal interface and in the periphery during pregnancy in both humans and mice. These cells exhibit immunosuppressive properties, and their abundance is associated with a Th2 skewed immune response, as their depletion results in a proinflammatory immune response at the fetomaternal interface. In addition to their function in suppressing proinflammatory responses in vitro, maternal CD71+ erythroid cells inhibit an aggressive allogeneic response directed against the fetus such as reduction in TNF-α and IFN-γ production through arginase-2 activity and PD-1/programmed death ligand-1 (PDL-1) interactions. Their depletion leads to the failure of gestation due to the immunological rejection of the fetus. Similarly, fetal liver CD71+ erythroid cells exhibit immunosuppressive activity. Therefore, immunosuppression mediated by CD71+ erythroid cells on both sides (mother/fetus) is crucial for fetomaternal tolerance. Thus, our results reveal a previously unappreciated role for CD71+ erythroid cells in pregnancy and indicate that these cells mediate homeostatic immunosuppressive/immunoregulatory responses during pregnancy.

Psychometric Properties of the Parental Bonding Instrument in a Sample of Canadian Children.

The parental bonding instrument (PBI) is a self-report questionnaire that was initially designed to retrospectively assess perceived parenting style during childhood in adult respondents. Recent studies have used the PBI to assess current perception of parenting in children. However, few studies have evaluated the psychometric properties of the PBI in children. This study examined the factor structure and reliability of the PBI in a sample of Canadian children aged 7-18 years (n = 257). Confirmatory factor analyses (CFA) were conducted separately for the mother and father form of the PBI and composite reliability was used to determine internal consistency of the PBI. A four-factor model (care, overprotection, autonomy, indifference) showed the best fit to the data. The PBI exhibited good internal consistency but poor convergent validity. Configural invariance was not found for the PBI between two age groups (7-12 and 13-18 years), however these findings should be interpreted with caution due to the small sample size in each age group. This study suggests the PBI may be a valid and reliable self-report measure of parental bonding in children but further research is needed.

Measuring Perceived Receipt of Filial Piety among Chinese Middle-Aged and Older Adults.

Filial piety plays an important role in the parent-child relationship in Chinese culture. To date, the majority of studies have focused on filial piety attitudes and expectations from the perspectives of the adult child. With only a few studies examining filial piety from the parent's perspectives, there is a paucity of studies that examines the dimensionality of filial piety receipt. The objective of this study was to validate the Perceived Receipt of Filial Piety Scale (PRFPS), a 10-item questionnaire designed to measure how often Chinese parents perceive their child(ren) engage in filial pious behaviours. A total of 222 middle-aged and older adult Chinese parents (Mage = 67.91, SD = 13.20) completed the PRFPS, MultidimensionalScale of Perceived Social Support (MSPSS) and the Quality of Life Scale (QOLS). A single-factor structure emerged from the developed PRFPS, which demonstrated excellent internal consistency (α = .95). The scale was also significantly associated with the MSPSS (r = .50) and QOLS (r = .42), supporting convergent and criterion validity. In conclusion, the PRFPS is found to be a reliable and valid measure of perceived filial piety receipt among Chinese parents. Theoretical implications and suggestions for further scale development and research is discussed.

Efficacy and safety of ozanimod in multiple sclerosis: Dose-blinded extension of a randomized phase II study.

BACKGROUND: Ozanimod, an oral immunomodulator, selectively targets sphingosine 1-phosphate receptors 1 and 5. OBJECTIVE: Evaluate efficacy, safety, and tolerability of ozanimod in relapsing multiple sclerosis. METHODS: In the RADIANCE Part A phase II study (NCT01628393), participants with relapsing multiple sclerosis were randomized (1:1:1) to once-daily ozanimod hydrochloride (0.5 or 1 mg) or placebo. After 24 weeks, participants could enter a 2-year, dose-blinded extension. Ozanimod-treated participants continued their assigned dose; placebo participants were re-randomized (1:1) to ozanimod hydrochloride 0.5 or 1 mg (equivalent to ozanimod 0.46 and 0.92 mg). RESULTS: A total of 223 (89.6%) of the 249 participants completed the blinded extension. At 2 years of the extension, the percentage of participants who were gadolinium-enhancing lesion-free ranged from 86.5% to 94.6%. Unadjusted annualized relapse rate during the blinded extension (week 24-end of treatment) was 0.32 for ozanimod hydrochloride 0.5 mg → ozanimod hydrochloride 0.5 mg, 0.18 for ozanimod hydrochloride 1 mg → ozanimod hydrochloride 1 mg, 0.30 for placebo → ozanimod hydrochloride 0.5 mg, and 0.18 for placebo → ozanimod hydrochloride 1 mg. No second-degree or higher atrioventricular block or serious opportunistic infection was reported. CONCLUSION: Ozanimod demonstrated sustained efficacy in participants continuing treatment up to 2 years and reached similar efficacy in participants who switched from placebo; no unexpected safety signals emerged.

Noninvasive Methods For Assessing Inflammatory Bowel Disease Activity in Pregnancy: A Systematic Review.

Active inflammatory bowel disease (IBD) may increase the risk of adverse outcomes during pregnancy. Our aim was to systematically review the role of noninvasive fecal tests, such as fecal calprotectin (FCP) and lactoferrin (FL), and laboratory tests including C-reactive protein (CRP), hemoglobin, and albumin in the assessment of IBD during pregnancy. A systematic search of electronic databases was performed through October 2018 for studies assessing the utility of fecal and laboratory tests in predicting IBD activity in pregnant patients. Active disease was defined based on routinely used clinical criteria such as the Harvey-Bradshaw Index or Mayo score for ulcerative colitis. Noninvasive test levels were stratified by the presence of active disease and by gestational period (preconception, first trimester, second trimester, and third trimester). Thirteen studies were included. Both FCP and FL levels were significantly higher in pregnant patients with IBD compared with those without IBD. FCP levels were also significantly higher in patients with active disease compared with those with the inactive disease during all gestational periods. Furthermore, 3 studies demonstrated no consistent correlation with serum CRP and active IBD during pregnancy. Similarly, serum albumin and hemoglobin levels did not correlate with disease activity in pregnant patients with IBD. Given the lack of high-quality evidence, only FCP appears to correlate with IBD activity in all gestational periods of pregnancy. The utility of the other noninvasive tests such as serum CRP, hemoglobin, and albumin remains to be determined in this population.

Mental health knowledge and training needs among direct care workers: a mixed methods study.

OBJECTIVES: Direct care providers (DCWs) spend the most time with clients in the home, and as such, play an integral role in identifying mental health problems. However, DCWs receive little preparation in mental health and there is little research regarding their role in the mental health care of clients. The purpose of this study was to explore DCWs' knowledge, attitudes, and experiences of caring for clients with mental health problems from the perspectives of DCWs and key administrators (KAs). METHOD: Mixed method design. Structured interviews were conducted with DCWs. Focus groups were conducted with KAs. RESULTS: Twenty-nine DCWs and 12 KAs took part in the study. Loneliness and memory problems in clients were the most prevalent challenges identified by DCWs. DCWs' self-reported mental health knowledge was mid to high across all domains, although they had many misconceptions about mental health and aging. Helpful strategies in working with clients included communication skills, rapport-building, behavioral, cognitive, emotion-regulation, and making use of external resources. KAs noted individual differences in DCWs' mental health knowledge and indicated that mental health issues were often viewed by DCWs as dispositional problems or a normal part of aging. KAs viewed DCWs' greatest challenges as personalizing difficult client behaviors, lack of knowledge about how to manage specific behaviors, and difficulties managing their own emotions towards clients. CONCLUSION: Data from this study suggest important areas for DCW development. However, system issues that affect DCWs such as workload, resources, mental health stigma, and diverse client populations should be addressed concurrently.
