RESUMEN

BACKGROUND: Intrauterine exposure to hypertensive disorders of pregnancy, including gestational hypertension (GH) and preeclampsia (PE), may influence infant growth and have long-term health implications. This study aimed to compare growth outcomes of infants exposed to a normotensive pregnancy (NTP), GH, or PE from birth to 2 years. METHODS: Infants were children of women enroled in the prospective Postpartum Physiology, Psychology and Paediatric (P4) cohort study who had NTP, GH or PE. Birth, 6-month (age-corrected) and 2-year (age-corrected) weight z-scores, change in weight z-scores, rapid weight gain (≥0.67 increase in weight z-score) and conditional weight gain z-scores were calculated to assess infant growth (NTP = 240, GH = 19, PE = 66). RESULTS: Infants exposed to PE compared to NTP or GH had significantly lower birth weight and length z-scores, but there were no differences in growth outcomes at 6 months or 2 years. GH and PE-exposed infants had significantly greater weight z-score gain [95% CI] (PE = 0.93 [0.66-1.18], GH = 1.03 [0.37-1.68], NTP = 0.45 [0.31-0.58], p < 0.01) and rapid weight gain (GH = 63%, PE = 59%, NTP = 42%, p = 0.02) from birth to 2 years, which remained significant for PE-exposed infants after confounder adjustment. CONCLUSION: In this cohort, GH and PE were associated with accelerated infant weight gain that may increase future cardiometabolic disease risk. IMPACT: Preeclampsia exposed infants were smaller at birth, compared with normotensive pregnancy and gestational hypertension exposed infants, but caught up in growth by 2 years of age. Both preeclampsia and gestational hypertension exposed infants had significantly accelerated weight gain from birth to 2 years, which remained significant for preeclampsia exposed infants after adjustment for confounders including small for gestational age. Monitoring of growth patterns in infants born following exposure to a hypertensive disorder of pregnancy may be indicated to prevent accelerated weight gain trajectories and obesity.

RESUMEN

Novel strategies are needed to target the health of postpartum women, who face numerous competing demands. This survey study of 553 postpartum women found 90% want access to a range of health information via social networking sites from reputable professionals, with Instagram (71%) the preferred platform. Delivery of health information to postpartum women via health organisation social networking sites could deliver cost savings and health benefits for postpartum women.

RESUMEN

BACKGROUND: Mental health is an integral part of overall health. Mental health disorders following childbirth are common and poor maternal mental health has consequences for both the mother and her infant. Preeclampsia is also relatively common in pregnancy but there is little known about the intersection between these two important conditions. Gaining a better understanding of the psychological consequences following preeclampsia is important, especially the link with depression, anxiety and posttraumatic stress disorder. If women who experience preeclampsia are recognised as being at increased risk of poor mental health, targeted screening in the postpartum period should be implemented. AIMS: To describe the prevalence and symptom severity of depression, anxiety and posttraumatic stress disorder at six months postpartum in women, who had a diagnosis of preeclampsia, compared to those who had normal blood pressure in pregnancy. METHODS: The mental health component of the prospective cohort study, the Postpartum, Physiology, Psychology and Paediatric follow-up study (P4 Study) was used. Women diagnosed with preeclampsia (n = 90) and those who were normotensive during pregnancy (n = 302) completed the Edinburgh Postnatal Depression Scale, General Anxiety Disorder Scale, and the Posttraumatic Stress Diagnostic Scale or Posttraumatic Stress Diagnostic Sclae-5 at six months postpartum. RESULTS: At six months postpartum, depressive scores were similar in both groups but a higher proportion of women from the preeclampsia group scored above the threshold for depression (2% v 7% p = 0.04). There were no differences between the groups in the prevalence or severity of anxiety or PTSD. However, more women in the preeclampsia group reported their birth experience as a traumatic event (1% vs 7%, p = 0.01). On correlation testing and modelling, booking Edinburgh Postnatal Depression Scale score, any mental health history, experiencing birth as traumatic and the General Anxiety Disorder Scale score were independent predictors of postpartum Edinburgh Postnatal Depression Scale scores. CONCLUSION: The postpartum clinical care of women with preeclampsia often focusses on the immediate physical health issues, but these women may also benefit from mental health screening. Targeted screening of preeclamptic women in the postpartum period may lead to more timely referral and initiation of treatment. TRIAL REGISTRATION: Retrospectively registered on 18/11/2013 with the Australian and New Zealand Clinical Trials Registry. Registration Number: ACTRN12613001260718 .

RESUMEN

BACKGROUND: Hypertensive disorders of pregnancy have longer-term implications, increasing women's lifetime cardiovascular disease risk. The Blood Pressure Postpartum study is a multi-centre randomised three-arm trial of interventions, ranging in intensity and including education and lifestyle coaching, to support women to maintain or adopt healthy eating and physical activity during the first postpartum year. This qualitative sub-study nested within the main trial aimed to investigate whether and how women adopted healthy behaviours after a pregnancy complicated by a hypertensive disorder. METHODS: Semi-structured telephone interviews were recorded, transcribed and analysed thematically, following Braun and Clarke principles. They explored behaviour change among new mothers following their hypertensive pregnancy, and the intervention's effect on their capacity and motivation to pursue healthy lifestyles. RESULTS: Thirty-four women from all three trial arms participated at 10-12 months postpartum. The three main themes were 1) Awareness of cardiovascular risk: some did not acknowledge the health risks, whereas others embraced this information. 2) Sources of motivation: while the majority were motivated to make a concerted effort to adapt their health behaviour, motivation often centred on their baby and family rather than their own needs. 3) Sustaining behaviour change with a new baby: women in the more intensive intervention arm demonstrated increased recognition of the importance of reducing cardiovascular health risks, with greater motivation and guidance to change their health behaviour. There was minimal evidence of crossover amongst groups, with women largely accepting their randomised level of intervention and not seeking additional help when randomised to minimal intervention. CONCLUSIONS: Among women participating in an early post-hypertensive disorders of pregnancy randomised controlled trial aimed at improving their cardiovascular disease risk profile, the majority recognised the future health risks and appeared motivated to improve their lifestyle, particularly women in the highest-intensity intervention group. This highlights the importance of structured support to assist women embrace healthy lifestyles especially during the challenges of new parenthood. TRIAL REGISTRATION: The Blood Pressure Postpartum study was prospectively registered as a clinical trial with the Australian New Zealand Clinical Trials Registry (anzctr.org.au) on 13 December 2018 (registration number: ACTRN12618002004246).

RESUMEN

BACKGROUND: Hypertensive disorders of pregnancy (HDP) affect 5-10% of pregnant women. Long-term health issues for these women include 2-3 times the risk of heart attacks, stroke and diabetes, starting within 10 years after pregnancy, making long-term health after HDP of major public health importance. Recent studies suggest this knowledge is not being transferred sufficiently to women and how best to transmit this information is not known. This study explored women's preferred content, format and access to education regarding long-term health after HDP. METHODS: This was a qualitative study and framework analysis was undertaken. Women with a history of HDP who had participated in a survey on long-term health after HDP were invited to participate in this study. During telephone interviews women were asked about preferences and priorities concerning knowledge acquisition around long-term health after HDP. RESULTS: Thirteen women were interviewed. They indicated that they wanted more detailed information about long-term and modifiable risk factors. Their preference was to receive risk counselling from their healthcare provider (HCP) early after giving birth along with evidence-based, print or web-based information to take home. All women suggested more structured postnatal follow-up, with automated reminders for key appointments. Automated reminders should detail rationale for follow-up, recommended tests and discussion topics to be addressed at the appointment. CONCLUSION: Our findings show that most participants wanted information soon after birth with all women wanting information within 12 months post birth, complemented with detailed take-home evidence. Participants indicated preference for structured follow-up via their HCP with automated alerts about the appointment and recommended tests. This evidence can be used to guide the development of education programs for women on health after HDP which may enhance knowledge, preventive health management and more generally improve women's health trajectories.

RESUMEN

INTRODUCTION: Maternal corticosteroid administration for anticipated preterm birth is common; however, the corticosteroid effect on fetal ultrasound and cardiotocograph (CTG) remains contested. This study aimed to evaluate short-term ultrasound and CTG impact of (a) dexamethasone versus betamethasone (b) pooled corticosteroid effect. METHODS: Substudy of blinded randomized trial of dexamethasone versus betamethasone (given <34 weeks). Umbilical artery (UA), middle cerebral artery (MCA), ductus venosus (DV), and uterine artery Doppler, myocardial performance index (MPI), biophysical profile (BPP), and CTG measured pre-corticosteroid then 1, 2, 4, and 7 days post-corticosteroid. RESULTS: Of 47 fetuses (39 singleton; 4 dichorionic, diamniotic twins; and 4 monochorionic, diamniotic twins) in the February 2012-2013 period, 24 received dexamethasone and 23 betamethasone at average gestation 29.8 ± 2.9 weeks. Thirteen pregnancies (30%) had pre-corticosteroid fetal concerns (estimated weight <10th centile and/or abnormal UA/MCA Doppler). Few significant differences were seen post-corticosteroid: DV pulsatility index and right MPI initially decreased 15-20%, and average BPP decreased slightly on days 1-2. There were no major differential effects of dexamethasone versus betamethasone. DISCUSSION/CONCLUSION: No substantive post-corticosteroid effects were seen for most ultrasound/CTG measures in fetuses with heightened preterm birth risk but predominantly normal pre-corticosteroid measures. Clinically, this suggests avoiding overreliance on individual measures for delivery decisions post-corticosteroid; equally, multiple/marked ultrasound changes suggest true pathology and not corticosteroid effect.

RESUMEN

There is a growing body of research evidencing the benefits of dedicated interprofessional placements in preparing healthcare students for interprofessional practice. However, little is known about if and how students develop their interprofessional identity during interprofessional placements. This study addresses this knowledge gap by exploring final-year students' interprofessional identity development during dedicated interprofessional placement(s). Thirty-eight students from five health professions were interviewed and data analyzed inductively to identify themes. Participants also drew images representing their perceptions of interprofessional identity and its relationship to professional identity as part of the data collection. The themes showed participants progressed from conceptualizing interprofessional identity as a requirement of the placement at the start of the placement, toward internalizing an interprofessional identity by the end of their placement. Context influences interprofessional identity salience. A commitment from healthcare professionals to model interprofessional practice, combined with explicitly facilitating interprofessional identity development, is recommended to facilitate continued interprofessional identity development in different contexts post placement.

RESUMEN

This article presents data from questions about sex offender registration orders in a large national survey on Australian public opinion about adult sex offenders. It outlines the legislative frameworks that govern these registers in Australia and discusses the use of public registers, the research on the effectiveness of sex offender registers, and Australian attitudes to such registers. Our surveys of three cohorts of members of the Australian public reveal strong public support for sex offender registers, especially for cases involving child victims. However, there was also support for judicial discretion in the imposition of orders and reduced support for automatic registration where a non-custodial sentence is imposed. The Australian Government has recently announced the establishment of a national public sex offender register, but our findings show limited support for this approach. The implications for policy and practice are considered.

RESUMEN

BACKGROUND: Hypertensive disorders of pregnancy (HDP) affect 5-10% of pregnant women. Women after HDP have 2-3 times increased risk of heart attack, stroke and diabetes, as soon as 5-10 years after pregnancy. Australian healthcare providers' knowledge of cardiovascular disease (CVD) risks for women after HDP is unknown, and this study aimed to explore their current knowledge and practice regarding long-term cardiovascular health after HDP, as a precursor to producing targeted healthcare provider education on health after HDP. METHODS: A custom-created, face-validated online survey explored knowledge about long-term risks after HDP. Distribution occurred from February to July 2019 via professional colleges, key organisations and social media. The objective was to assess current knowledge and knowledge gaps amongst a group of healthcare providers (HCP) in Australia, regarding long-term cardiovascular health after hypertensive disorders of pregnancy (HDP), specifically gestational hypertension or preeclampsia. RESULTS: Of 492 respondents, 203 were midwives, 188 obstetricians, 75 general practitioners (GP), and 26 cardiologists. A risk knowledge score was computed with 0-6 considered low, 6.1-8.9 moderate and 9-12 high. Most participants (85%) were aware of increased cardiovascular disease after preeclampsia and gestational hypertension (range 76% midwives to 100% cardiologists). There were significant differences in average knowledge scores regarding health after preeclampsia; high for cardiologists (9.3), moderate for GPs and obstetricians (8.2 and 7.6 respectively) and low for midwives (5.9). Average knowledge scores were somewhat lower for gestational hypertension (9.0 for cardiologists, 7.4 for obstetricians and GPs, 5.1 for midwives). Knowledge was highest regarding risk of chronic hypertension, moderate to high regarding risk of ischaemic heart disease, stroke and recurring HDP, and low for diabetes and peripheral vascular disease. Only 34% were aware that risks start < 10 years after the affected pregnancy. CONCLUSION(S): Participants were aware there is increased cardiovascular risk after HDP, although less aware of risks after gestational hypertension and some specific risks including diabetes. Findings will inform the development of targeted education.

RESUMEN

Undergraduate psychology students have been largely excluded from interprofessional education (IPE) initiatives. In contrast to many health professions, undergraduate psychology students do not engage in work placements as part of their degree, and many enter careers outside the health care context. However, the collaborative skills gained through an IPE experience may well be beneficial to students who work in this wider context. This research examines whether undergraduate psychology students' views of IPE vary according to their planned career directions, and if so, whether the perceived relevance of IPE mediates the relationships. A sample of 188 Australian university undergraduate psychology students completed an online questionnaire following completion of a first-year IPE health sciences program. Path analysis indicated that psychology students' attitudes towards IPE are associated with both professional identification and practitioner orientation, fully mediated through the perceived relevance of IPE to future career and study plans. Stronger professional identification and practitioner orientation were associated with greater perceived relevance and more positive and less negative attitudes towards IPE. Placing a stronger emphasis on the generalizability of IP skills taught may increase students' awareness of the relevance outside of the health context, reducing disengagement of students planning alternative careers.

RESUMEN

Intellectual disability is commonly conceptualised as stigmatised identity; however, within the literature, the notion of a damaged identity is contested. The aim of this research was to explore the social construction of intellectual disability from the perspective of staff who work closely with people with intellectual disabilities. Informed by a contextualist perspective, this research was based on interviews with five staff members of an advocacy agency in a regional area of Australia. Causal layered analysis was used to deconstruct the interview data. Analysis of the interactions that emerged across the causal layers revealed a complex dynamic of world views, which served to dehumanise people with intellectual disabilities and blame them for their own fate (victim blaming). For transformative change to occur, understandings of the 'problems' of intellectual disability must be reformulated and those social structures and processes that support the relationship between the powerful and the powerless must be challenged.

RESUMEN

The plant cytotoxin ricin enters mammalian cells by receptor-mediated endocytosis, undergoing retrograde transport to the ER (endoplasmic reticulum) where its catalytic A chain (RTA) is reductively separated from the holotoxin to enter the cytosol and inactivate ribosomes. The currently accepted model is that the bulk of ER-dislocated RTA is degraded by proteasomes. We show in the present study that the proteasome has a more complex role in ricin intoxication than previously recognized, that the previously reported increase in sensitivity of mammalian cells to ricin in the presence of proteasome inhibitors simply reflects toxicity of the inhibitors themselves, and that RTA is a very poor substrate for proteasomal degradation. Denatured RTA and casein compete for a binding site on the regulatory particle of the 26S proteasome, but their fates differ. Casein is degraded, but the mammalian 26S proteasome AAA (ATPase associated with various cellular activities)-ATPase subunit RPT5 acts as a chaperone that prevents aggregation of denatured RTA and stimulates recovery of catalytic RTA activity in vitro. Furthermore, in vivo, the ATPase activity of Rpt5p is required for maximal toxicity of RTA dislocated from the Saccharomyces cerevisiae ER. The results of the present study implicate RPT5/Rpt5p in the triage of substrates in which either activation (folding) or inactivation (degradation) pathways may be initiated.

RESUMEN

Risk factors for stalking violence are not well understood and few studies have examined psychological distress and substance use specifically. This study aimed to assess whether factors extant in police data could predict severity of stalking violence against intimate partner victims. Western Australia Police Force provided data for 603 men linked to a stalking charge relating to a female intimate partner. Binomial logistic regressions showed police-identified histories of psychological distress and drug use predicted moderate violence, but not severe violence. A co-occurring history of drug use and alcohol use was the strongest predictor of moderate violence (OR = 6.8). These findings suggest accounting for violence severity and substance type when examining stalking violence risk factors. Whether psychological distress and/or substance use were active problems for the men during their stalking behavior is unknown, however the detection of these problems may indicate an unmet need for treatment among this group.

RESUMEN

OBJECTIVES: To assess the ability of the USCOM® (USCOM), using measurements of cardiac output (CO) and systemic vascular resistance (SVR), to predict the development of pre-eclampsia (PE) and severe PE in hypertensive pregnancies. STUDY DESIGN: Prospective cohort study of women in the second or third trimester recruited at a tertiary center in Sydney, Australia. Demographic data and hemodynamic measurements using the USCOM were taken for all study participants at recruitment. Pregnancy outcome, including development of PE and severe PE, was tracked. Data were analyzed using ANOVA testing, pair-wise comparison testing, and Student's t-testing. RESULTS: Recruitment included 65 normotensive controls, 34 women with chronic hypertension (CH), 51 with gestational hypertension (GH), and 21 with PE. Significantly higher weight, body surface area, and blood pressure measurements were found in the hypertensive, compared with the normotensive control and pregnancies. There were no observed differences in USCOM-measured CO, cardiac index, SVR, or systemic vascular resistance index between hypertensive women who did versus did not develop PE or severe PE in later pregnancy. Analysis of the CH and GH subgroups, as well as only unmedicated hypertensive women (n = 24), also showed no significant difference in hemodynamic parameters between those who did or did not develop PE or severe PE. CONCLUSIONS: Our group was unable to successfully predict the onset of PE or severe PE based on hemodynamic parameters measured with the USCOM. It is possible this relates to the high proportion of women on antihypertensive medication at recruitment.

RESUMEN

BACKGROUND: Postpartum mental illnesses and hypertensive disorders of pregnancy (HDP) are both common, and both associated with adverse maternal and child health outcomes. However, the relationship between them is unclear. This study aimed to investigate prevalence and symptom severity of depression, anxiety, and post-traumatic stress disorder (PTSD) 2-years postpartum in women with normal blood pressure (NBP) during pregnancy versus preeclampsia or gestational hypertension (GH). METHODS: Two-years follow-up of the prospective Postpartum, Physiology, Psychology and Paediatric (P4) Cohort Study was conducted in metropolitan Australia. Prevalence and symptom severity of depression (Edinburgh Postnatal Depression Scale, EPDS > 12), anxiety (7-item Generalized Anxiety Disorder scale, GAD-7 ≥ 10) and PTSD (Posttraumatic stress Diagnostic Scale, PDS/PDS-5) were measured and calculated for women with NBP, preeclampsia and GH. RESULTS: Among 365 participants (NBP: n = 271, preeclampsia: n = 75, GH: n = 19), 2-years postpartum depression prevalence was 3.9% (95% CI 2.3-6.4%): 4.4% after NBP, and 2.7% after preeclampsia (p = 0.53). Anxiety prevalence was higher after GH than NBP (15.8% versus 3.3%, p = 0.02). Prevalence of any mental illness (depression/anxiety/PTSD) was 5.9% (95% CI 3.8-8.8%); 5.6% after NBP, 4.1% after PE, and 15.8% after GH (p = 0.15). Although PTSD prevalence was low (1.4%), and similar between groups (p = 0.97), around 3 times more women after PE (8.1%), compared to NBP (2.5%), recalled childbirth as traumatic (p = 0.003). CONCLUSIONS: Preeclampsia, although associated with persistent perceptions of traumatic childbirth, did not alter the risk of mental illnesses at 2-years postpartum. GH (albeit in a small subgroup) was associated with increased anxiety scores. Larger, multicentre studies are required to clarify relationships between HDP and postpartum mental illness. TRIAL REGISTRATION: Retrospectively registered on 18/11/2013 with the Australian and New Zealand Clinical Trials Registry. REGISTRATION NUMBER: ACTRN 12613 00,126 0718.

RESUMEN

BACKGROUND: Increased cardiovascular risk following preeclampsia is well established and there are signs of early cardiovascular aging 6 months postpartum. This study assessed whether blood pressure (BP) and other cardiovascular measures are abnormal 2 years postpartum in the same cohort to determine ongoing risk markers. METHODS: Six months and 2 years postpartum, BP was measured using sphygmomanometry, 24-hour ambulatory BP monitoring, and noninvasive central BP. Anthropometric measures, blood, and urine biochemistry were performed. Cross-sectional comparisons between preeclampsia and normotensive pregnancy (NP) groups and longitudinal comparisons within each group were made at 6 months and 2 years. RESULTS: Two years postpartum, 129 NP, and 52 preeclampsia women were studied who also had 6 months measures. At both time points, preeclampsia group had significantly higher BP (office BP 2 years, 112±12/72±8 versus 104±9/67±7 mm Hg NP; [P<0.001]; mean ambulatory BP monitoring 116±9/73±8 versus 106±8/67±6 mm Hg NP; [P<0.001]). No significant BP changes noted 6 months to 2 years within either group. Office BP thresholds of 140 mm Hg systolic and 90 mm Hg diastolic classified 2% preeclampsia and 0% NP at 2 years. American Heart Association 2017 criteria (above normal, >120/80 mm Hg) classified 25% versus 8% (P<0.002), as did our reference range threshold of 122/79 mm Hg. American Heart Association criteria classified 60% post-preeclampsia versus 16% after NP with above-normal ambulatory BP monitoring (P<0.001). Other cardiovascular risk markers more common 2 years post-preeclampsia included higher body mass index (median 26.6 versus 23.1, P=0.003) and insulin resistance. CONCLUSIONS: After preeclampsia, women have significantly higher BP 6 months and 2 years postpartum, and have higher body mass index and insulin-resistance scores, increasing their future cardiovascular risk. Regular cardiovascular risk screening should be implemented for all who have experienced preeclampsia.

RESUMEN

Preeclampsia is associated with an increased risk of long-term cardiometabolic disease; however, little is known regarding metabolic factors in the early postpartum years potentially contributing to these health disparities. This study aimed to compare body composition, serum biochemical parameters, energy balance and diet 6 months and 2 years after normotensive pregnancy versus preeclampsia. This is the longitudinal metabolic sub-study of the Postpartum Physiology, Psychology and Paediatric cohort study. Women were assessed 6 months and 2 years after normotensive pregnancy (n = 118) and preeclampsia (n = 47). Metabolic measures included anthropometry, body composition via bioelectrical impedance analysis, serum biochemical parameters, diet via a food recall diary, and 24-h energy expenditure using SenseWear Armbands. Two years postpartum, women after preeclampsia continued to have significantly higher weight (median 67.1 kg vs. 63.1 kg, p = .04) compared to normotensive pregnancies, in addition to higher LDL cholesterol levels (2.7 ± 0.8 mmol/L vs. 2.4 ± 0.6 mmol/L, p = .03). These women were also more likely to have an elevated HOMA-IR score ≥2.08 (44% vs. 19%, p = .01). For all women in our study, waist-to-hip ratio, percent fat mass and activity-associated energy expenditure improved overtime. However, HDL cholesterol levels deteriorated, and excess saturated fat and sodium intake persisted from 6 months postpartum. Therefore, two years after preeclampsia, women remain at greater metabolic risk than their normotensive counterparts, with greater weight, LDL cholesterol and markers of insulin resistance, potentially contributing to long-term cardiovascular morbidity and requiring early intervention.

RESUMEN

We screened a panel of compounds derived from Exo2 - a drug that perturbs post-Golgi compartments and trafficking in mammalian cells - for their effect on the secretory pathway in Arabidopsis root epidermal cells. While Exo2 and most related compounds had no significant effect, one Exo2 derivative, named LG8, induced severe morphological alterations in both the Golgi (at high concentrations) and the endoplasmic reticulum (ER). LG8 causes the ER to form foci of interconnecting tubules, which at the ultrastructural level appear similar to those previously reported in Arabidopsis roots after treatment with the herbicide oryzalin. In cotyledonary leaves, LG8 causes redistribution of a trans Golgi network (TGN) marker to the vacuole. LG8 affects the anterograde secretory pathway by inducing secretion of vacuolar cargo and preventing the brassinosteroid receptor BRI1 from reaching the plasma membrane. Uptake and arrival at the TGN of the endocytic marker FM4-64 is not affected. Unlike the ADP ribosylation factor-GTP exchange factor (ARF-GEF) inhibitor brefeldin A (BFA), LG8 affects these post-Golgi events without causing the formation of BFA bodies. Up to concentrations of 50 µm, the effects of LG8 are reversible.

RESUMEN

The endoplasmic reticulum (ER) is a network of membrane sheets and tubules connected via three-way junctions. A family of proteins, the reticulons, are responsible for shaping the tubular ER. Reticulons interact with other tubule-forming proteins (Dp1 and Yop1p) and the GTPase atlastin. The Arabidopsis homologue of Dp1/Yop1p is HVA22. We show here that a seed-specific isoform of HVA22 labels the ER in tobacco (Nicotiana tabacum) cells but its overexpression does not alter ER morphology. The closest plant homologue of atlastin is RHD3. We show that RHD3-like 2 (RL2), the seed-specific isoform of RHD3, locates to the ER without affecting its shape or Golgi mobility. Expression of RL2-bearing mutations within its GTPase domain induces the formation of large ER strands, suggesting that a functional GTPase domain is important for the formation of three-way junctions. Coexpression of the reticulon RTNLB13 with RL2 resulted in a dramatic alteration of the ER network. This alteration did not depend on an active GTPase domain but required a functional reticulon, as no effect on ER morphology was seen when RL2 was coexpressed with a nonfunctional RTNLB13. RL2 and its GTPase mutants coimmunoprecipitate with RTNLB13. These results indicate that RL2 and RTNLB13 act together in modulating ER morphology.

RESUMEN

BACKGROUND: Cognitive-behavioral therapy (CBT) has demonstrated efficacy and effectiveness for treating mood and anxiety disorders. Dissemination of CBT via videoconference may help improve access to treatment. OBJECTIVE: The present study aimed to compare the effectiveness of CBT administered via videoconference to in-person therapy for a mixed diagnostic cohort. METHODS: A total of 26 primarily Caucasian clients (mean age 30 years, SD 11) who had a primary Diagnostic and Statistical Manual of Mental Disorders, 4th edition text revision (DSM-IV-TR) diagnosis of a mood or anxiety disorder were randomly assigned to receive 12 sessions of CBT either in-person or via videoconference. Treatment involved individualized CBT formulations specific to the presenting diagnosis; all sessions were provided by the same therapist. Participants were recruited through a university clinic. Symptoms of depression, anxiety, stress, and quality of life were assessed using questionnaires before, after, and 6 weeks following treatment. Secondary outcomes at posttreatment included working alliance and client satisfaction. RESULTS: Retention was similar across treatment conditions; there was one more client in the videoconferencing condition at posttreatment and at follow-up. Statistical analysis using multilevel mixed effects linear regression indicated a significant reduction in client symptoms across time for symptoms of depression (P<.001, d=1.41), anxiety (P<.001, d=1.14), stress (P<.001, d=1.81), and quality of life (P<.001, d=1.17). There were no significant differences between treatment conditions regarding symptoms of depression (P=.165, d=0.37), anxiety (P=.41, d=0.22), stress (P=.15, d=0.38), or quality of life (P=.62, d=0.13). There were no significant differences in client rating of the working alliance (P=.53, one-tailed, d=-0.26), therapist ratings of the working alliance (P=.60, one-tailed, d=0.23), or client ratings of satisfaction (P=.77, one-tailed, d=-0.12). Fisher's Exact P was not significant regarding differences in reliable change from pre- to posttreatment or from pretreatment to follow-up for symptoms of depression (P=.41, P=.26), anxiety (P=.60, P=.99), or quality of life (P=.65, P=.99) but was significant for symptoms of stress in favor of the videoconferencing condition (P=.03, P=.035). Difference between conditions regarding clinically significant change was also not observed from pre- to posttreatment or from pretreatment to follow-up for symptoms of depression (P=.67, P=.30), anxiety (P=.99, P=.99), stress (P=.19, P=.13), or quality of life (P=.99, P=.62). CONCLUSIONS: The findings of this controlled trial indicate that CBT was effective in significantly reducing symptoms of depression, anxiety, and stress and increasing quality of life in both in-person and videoconferencing conditions, with no significant differences being observed between the two.
