Comparison of Anti-SARS-CoV-2-Specific Antibody Signatures in Maternal and Infant Blood after COVID-19 Infection versus COVID-19 Vaccination during Pregnancy.

OBJECTIVE: The Advisory Committee on Immunization Practices and The American College of Obstetricians and Gynecologists recommend coronavirus disease 2019 (COVID-19) vaccine for pregnant persons to prevent severe illness and death. The objective was to examine levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) IgG, IgM, and IgA against spike protein receptor binding domain (RBD) and nucleocapsid protein (NCP) in maternal and infant/cord blood at delivery after COVID 19 vaccination compared with SARS-CoV-2 infection at in mother-infant dyads at specified time points. STUDY DESIGN: Mothers with SARS-CoV-2 infection (n = 31) or COVID-19 vaccination (n = 25) during pregnancy were enrolled between July 2020 and November 2021. Samples were collected at delivery and IgG, IgM, and IgA to RBD of spike and NCPs compared in the infected and vaccinated groups. Timing of infection/vaccination prior to delivery and correlation with antibody levels was performed. RESULTS: The majority of participants received vaccination within 90 days of delivery and over half received the Pfizer BioNTech vaccine. There were no significant correlations between antibody levels and timing of infection or vaccination. Infant IgG levels to the RBD domain of spike protein were higher in the vaccinated group (n = 25) as compared with the infants born to mothers with infection (n = 31). Vaccination against COVID-19 during pregnancy was associated with detectable maternal and infant anti-RBD IgG levels at delivery irrespective of the timing of vaccination. CONCLUSION: Timing of vaccination had no correlation to the antibody levels suggesting that the timing of maternal vaccination in the cohort did not matter. There was no IgM detected in infants from vaccinated mothers. Infants from vaccinated mothers had robust IgG titers to RBD, which have a lasting protective effect in infants. KEY POINTS: · COVID-19 vaccination during pregnancy had detectable antibody.. · No correlation between antibody levels and timing of vaccination.. · Infants from vaccinated mothers had robust IgG titers to RBD..

The contribution of depressive 'disorder characteristics' to determinations of prognosis for adults with depression: an individual patient data meta-analysis.

BACKGROUND: This study aimed to investigate general factors associated with prognosis regardless of the type of treatment received, for adults with depression in primary care. METHODS: We searched Medline, Embase, PsycINFO and Cochrane Central (inception to 12/01/2020) for RCTs that included the most commonly used comprehensive measure of depressive and anxiety disorder symptoms and diagnoses, in primary care depression RCTs (the Revised Clinical Interview Schedule: CIS-R). Two-stage random-effects meta-analyses were conducted. RESULTS: Twelve (n = 6024) of thirteen eligible studies (n = 6175) provided individual patient data. There was a 31% (95%CI: 25 to 37) difference in depressive symptoms at 3-4 months per standard deviation increase in baseline depressive symptoms. Four additional factors: the duration of anxiety; duration of depression; comorbid panic disorder; and a history of antidepressant treatment were also independently associated with poorer prognosis. There was evidence that the difference in prognosis when these factors were combined could be of clinical importance. Adding these variables improved the amount of variance explained in 3-4 month depressive symptoms from 16% using depressive symptom severity alone to 27%. Risk of bias (assessed with QUIPS) was low in all studies and quality (assessed with GRADE) was high. Sensitivity analyses did not alter our conclusions. CONCLUSIONS: When adults seek treatment for depression clinicians should routinely assess for the duration of anxiety, duration of depression, comorbid panic disorder, and a history of antidepressant treatment alongside depressive symptom severity. This could provide clinicians and patients with useful and desired information to elucidate prognosis and aid the clinical management of depression.

Can gait outcomes be predicted early after a stroke?

PURPOSE: To determine the ability of clinical measures collected within 72 hours of neurological insult to predict independent gait 6 and 12 months after a stroke. METHODS: Patients with a confirmed stroke diagnosis were eligible for inclusion in this prospective cohort study. Sitting balance, National Institutes of Health Stroke Scale (NIHSS) motor leg, NIHSS motor arm, and Motricity Index (MI) were measured within 72 hours post-stroke. Follow-up assessments were conducted at 6 and 12 months post-stroke to measure gait recovery. RESULTS: A total of 78 patients were included at baseline for analysis. At 6 and 12 months, 38% (n = 38) and 35% (n = 42) of patients used a gait aid, and 80% and 87% were independently ambulant, respectively. Sitting balance, NIHSS motor leg, and NIHSS motor arm were not significantly associated with ambulation at 6 or 12 months or with the use of a gait aid. Thrombolysis was significantly associated with independent outdoors ambulation at 6 months (p = .011). A worse MI score was significantly associated with a higher number of falls at 6 months (p < .010) but not with the need for a gait aid. The number of falls at 6 months was independently predicted by urinary incontinence post-stroke (p < .001), NIHSS leg score (p < .005), and depression and anxiety while in acute care (p < .005). CONCLUSIONS: Clinical bedside assessments may be less important in predicting safe, independent gait than previously thought. Urinary incontinence and poor mental health should be addressed in the hospital. Increased utilization of reperfusion techniques may alter functional recovery patterns.

Cytokine levels in maternal and infant blood after COVID-19 vaccination during pregnancy in comparison with unvaccinated controls.

The objective of this study was to compare maternal and infant cytokine profiles at delivery among those vaccinated against SARS-CoV-2 during pregnancy to unvaccinated controls. Mother-infant dyads were enrolled in this prospective cohort study, and maternal blood and infant and/or cord blood collected. Samples were analyzed utilizing a LEGENDplex 13-plex human anti-viral response cytokine panel. Maternal IP-10 and IFN-λ2/3 were lower in the vaccinated cohort. In the infants, levels were lower for IL-1ß, IFN-λ2/3, and GM-CSF, and higher for IFN-λ1 in the vaccinated cohort. Vaccination against SARS-CoV-2 during pregnancy did not lead to elevations in cytokines in mothers or infants.

Maternal, Infant, and Breast Milk Antibody Response Following COVID-19 Infection in Early Versus Late Gestation.

BACKGROUND: Coronavirus disease 2019 [severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)] infection at varying time points during the pregnancy can influence antibody levels after delivery. We aimed to examine SARS-CoV-2 IgG, IgM and IgA receptor binding domain of the spike protein and nucleocapsid protein (N-protein) reactive antibody concentrations in maternal blood, infant blood and breastmilk at birth and 6 weeks after SARS-CoV-2 infection in early versus late gestation. METHODS: Mothers with SARS-CoV-2 infection during pregnancy were enrolled between July 2020 and May 2021. Maternal blood, infant blood and breast milk samples were collected at delivery and 6 weeks postpartum. Samples were analyzed for SARS-CoV-2 spike and N-protein reactive IgG, IgM and IgA antibodies. Antibody concentrations were compared at the 2 time points and based on trimester of infection ("early" 1st/2nd vs. "late" 3rd). RESULTS: Dyads from 20 early and 11 late trimester infections were analyzed. For the entire cohort, there were no significant differences in antibody levels at delivery versus 6 weeks with the exception of breast milk levels which declined over time. Early gestation infections were associated with higher levels of breastmilk IgA to spike protein ( P = 0.04). Infant IgG levels to spike protein were higher at 6 weeks after late infections ( P = 0.04). There were strong correlations between maternal and infant IgG levels at delivery ( P < 0.01), and between breastmilk and infant IgG levels. CONCLUSIONS: SARS-CoV-2 infection in early versus late gestation leads to a persistent antibody response in maternal blood, infant blood and breast milk over the first 6 weeks after delivery.

Exploring patients' experience of peer-supported open dialogue and standard care following a mental health crisis: qualitative 3-month follow-up study.

BACKGROUND: Experience of crisis care may vary across different care models. AIMS: To explore the experience of care in standard care and 'open dialogue' (a peer-supported community service focused on open dialogue and involving social networks for adults with a recent mental health crisis) 3 months after a crisis. METHOD: We conducted semi-structured interviews with 11 participants (6 received open dialogue; 5 received treatment as usual (TAU)) in a feasibility study of open dialogue and analysed the data using a three-step inductive thematic analysis to identify themes that (a) were frequently endorsed and (b) represented the experiences of all participants. RESULTS: Four themes emerged: (a) feeling able to rely on and access mental health services; (b) supportive and understanding family and friends; (c) having a choice and a voice; and (d) confusion and making sense of experiences. Generally, there was a divergence in experience across the two care models. Open dialogue participants often felt able to rely on and access services and involve their family and friends in their care. TAU participants described a need to rely on services and difficulty when it was not met, needing family and friends for support and wanting them to be more involved in their care. Some participants across both care models experienced confusion after a crisis and described benefits of sense-making. CONCLUSIONS: Understanding crisis care experiences across different care models can inform service development in crisis and continuing mental healthcare services.

Open Dialogue compared to treatment as usual for adults experiencing a mental health crisis: Protocol for the ODDESSI multi-site cluster randomised controlled trial.

Background 'Open Dialogue' is a social network model of crisis and continuing mental healthcare which involves elements of service delivery such as immediate response and a style of therapeutic meeting called network meetings. Although there are indications from non-randomised studies that it may help people in their recovery from severe mental health crises and improve long-term outcomes, this has yet to be tested in a randomised controlled trial. Methods This paper outlines the protocol for a multi-site cluster-randomised control trial assessing the clinical and cost-effectiveness of Open Dialogue compared to treatment as usual (TAU) for individuals presenting in crisis to six mental health services in England. The primary outcome is time to relapse, with secondary outcomes including measures of recovery and service use. Participants will be followed-up for two years, with data collected from electronic medical records and researcher-led interviews. The analysis will compare outcomes between treatment groups as well as investigating potential mediators of effect: shared decision-making and social network quality and size. Carers of a subsample of participants will be asked about their experiences of shared decision-making, carer burden, and satisfaction. Discussion This trial will provide evidence of whether Open Dialogue services implemented in the English mental health system is an effective alternative to current care and may have important implications for the organization of community mental health services. Trial registration: retrospectively registered (108 participants recruited of 570 target) on 20/12/2019, ISRCTN52653325.

The impact of maternal SARS-CoV-2 vaccination and first trimester infection on feto-maternal immune responses.

PROBLEM: COVID-19 infection during pregnancy increases maternal and fetal morbidity and mortality. Infection in the second or third trimester leads to changes in the decidual leukocyte populations. However, it is not known whether COVID-19 infection in the first trimester or COVID-19 vaccination during pregnancy alters the decidual immune environment. METHOD OF STUDY: We examined decidual biopsies obtained at delivery from women who had COVID-19 in the first trimester (n = 8), were fully vaccinated against COVID-19 during pregnancy (n = 17), or were neither infected nor vaccinated during pregnancy (n = 9). Decidual macrophages, NK cells, and T cells were quantified by immunofluorescence. Decidual IL-6, IL-10, and IP-10 were quantified by ELISA. RESULTS: There were no differences in decidual macrophages, NK cells, T cells, or cytokines between the first trimester COVID-19 group and the control group. The vaccinated cohort had lower levels of macrophages and NK cells compared to the control group. There were no differences in cytokines between the vaccinated and control groups. CONCLUSIONS: COVID-19 infection in the first trimester did not cause significant decidual leukocyte or cytokine changes at the maternal-fetal interface. Additionally, vaccination was not associated with decidual inflammation, supporting the safety of SARS-CoV-2 vaccination during pregnancy.

Evaluation of maternal-infant dyad inflammatory cytokines in pregnancies affected by maternal SARS-CoV-2 infection in early and late gestation.

OBJECTIVE: SARS-CoV-2 infection induces significant inflammatory cytokine production in adults, but infant cytokine signatures in pregnancies affected by maternal SARS-CoV-2 are less well characterized. We aimed to evaluate cytokine profiles of mothers and their infants following COVID-19 in pregnancy. STUDY DESIGN: Serum samples at delivery from 31 mother-infant dyads with maternal SARS-CoV-2 infection in pregnancy (COVID) were examined in comparison to 29 control dyads (Control). Samples were evaluated using a 13-plex cytokine assay. RESULTS: In comparison with controls, interleukin (IL)-6 and interferon gamma-induced protein 10 (IP-10) were higher in COVID maternal and infant samples (p < 0.05) and IL-8 uniquely elevated in COVID infant samples (p < 0.05). Significant elevations in IL-6, IP-10, and IL-8 were found among both early (1st/2nd Trimester) and late (3rd Trimester) maternal SARS-CoV-2 infections. CONCLUSIONS: Maternal SARS-CoV-2 infections throughout gestation are associated with increased maternal and infant inflammatory cytokines at birth with potential to impact long-term infant health.

Dysautonomia in 53 cats and dogs: retrospective review of clinical data and outcome.

BACKGROUND: Dysautonomia is a disease characterised by degeneration of autonomic neurons. METHODS: The aim of this study was to perform a retrospective multicentre review of clinical data relating to cats and dogs diagnosed with dysautonomia and to evaluate their outcome. RESULTS: Cats (n=34) and dogs (n=19) with clinical signs consistent with dysautonomia were considered for this retrospective study. Reported clinical findings included oesophageal and gastrointestinal dysmotility and distension, urinary retention, reduced or absent tear production, third eyelid protrusion and inappropriate mydriasis. Treatment was supportive and included gastrointestinal prokinetics, feeding tube placement (oesophageal and percutaneous endoscopic gastrostomy tubes) and medications to treat urinary retention. The survival to discharge was 29 per cent in cats and 47 per cent in dogs. The overall survival in cats was 21 per cent and that in dogs was 32 per cent. Survival of greater than 2 years was seen in six cats and in three dogs. CONCLUSION: This paper illustrates that some animals are able to survive this disease and can have a good long-term prognosis, which is an infrequently reported finding for this disease.

Postsynaptic action of GABA in modulating sensory transmission in co-cultures of rat carotid body via GABA(A) receptors.

GABA is expressed in carotid body (CB) chemoreceptor type I cells and has previously been reported to modulate sensory transmission via presynaptic GABA(B) receptors. Because low doses of clinically important GABA(A) receptor (GABA(A)R) agonists, e.g. benzodiazepines, have been reported to depress afferent CB responses to hypoxia, we investigated the potential contribution of GABA(A)R in co-cultures of rat type I cells and sensory petrosal neurones (PNs). During gramicidin perforated-patch recordings (to preserve intracellular Cl-), GABA and/or the GABA(A) agonist muscimol (50 microm) induced a bicuculline-sensitive membrane depolarization in isolated PNs. GABA-induced whole-cell currents reversed at approximately -38 mV and had an EC50 of approximately 10 microm (Hill coefficient = approximately 1) at -60 mV. During simultaneous PN and type I cell recordings at functional chemosensory units in co-culture, bicuculline reversibly potentiated the PN, but not type I cell, depolarizing response to hypoxia. Application of the CB excitatory neurotransmitter ATP (1 microm) over the soma of functional PN induced a spike discharge that was markedly suppressed during co-application with GABA (2 microm), even though GABA alone was excitatory. RT-PCR analysis detected expression of GABAergic markers including mRNA for alpha1, alpha2, beta2, gamma2S, gamma2L and gamma3 GABA(A)R subunits in petrosal ganglia extracts. Also, CB extracts contained mRNAs for GABA biosynthetic markers, i.e. glutamate decarboxylase (GAD) isoforms GAD 67A,E, and GABA transporter isoforms GAT 2,3 and BGT-1. In CB sections, sensory nerve endings apposed to type I cells were immunopositive for the GABA(A)R beta subunit. These data suggest that GABA, released from the CB during hypoxia, inhibits sensory discharge postsynaptically via a shunting mechanism involving GABA(A) receptors.

Testicular ischemia in deficiency of adenosine deaminase 2 (DADA2).

BACKGROUND: Deficiency of adenosine deaminase 2 (DADA2) is a rare autosomal recessive autoinflammatory condition. Recognised features include vasculitis predominantly affecting medium sized vessels, livedoid skin rash, central and peripheral nervous system involvement, variable degrees of immunodeficiency, and marrow failure, amongst other clinical presentations. We present the case of a six year old male with DADA2 who presented with acute testicular ischaemia secondary to vasculitis, the first such description in DADA2. CASE PRESENTATION: A six year old male presented acute right-sided testicular pain. His history included transient infantile neutropenia, resolved hepatosplenomegaly, and longstanding livedo racemosa, leading to screening and confirmation of DADA2 caused by homozygous c.139G > C (p.G47R) mutation of ADA2. As his only clinical feature was that of mild livedo racemosa with normal laboratory parameters at diagnosis, he was being actively monitored prior to starting any treatment. At a routine clinic follow-up a 24 h history of testicular pain was noted on systems review. He was afebrile, and his only physical signs were that of moderate livedo racemosa, and tenderness of the right testicle. Laboratory parameters revealed C-reactive protein (CRP) 8 mg/L (reference range [RR] < 20 mg/L); erythrocyte sedimentation rate (ESR) 28 mm/hr. (RR < 10); and serum amyloid A (SAA)5 mg/L (RR < 10). Ultrasound-scan of the scrotum revealed significantly reduced perfusion of the right testes, without torsion. Surgical scrotal exploration confirmed testicular ischaemia without torsion. Histology demonstrated ischaemic seminiferous tubules with intervening haemorrhage and acute inflammatory cells, consistent with vasculitis of the testis as the cause. He was treated with high dose intravenous methyl-prednisolone followed by a weaning course of oral prednisolone, and subcutaneous adalimumab (anti-tumour necrosis factor alpha, anti-TNFα). Repeat ultrasound-scan 3 weeks later revealed good testicular perfusion, with a small area of focal infarction. At last follow-up (11 months post-event) he remained asymptomatic, on treatment with adalimumab. CONCLUSION: The phenotype of DADA2 continues to expand, and we add testicular infarction to the features of DADA2. CRP and SAA cannot be relied on as reliable biomarkers to predict tissue ischaemia and hence who to target for anti-TNFα therapy in DADA2, since these remained steadfastly normal before, during, and after testicular infarction in this case.

What factors indicate prognosis for adults with depression in primary care? A protocol for meta-analyses of individual patient data using the Dep-GP database.

Background: Pre-treatment severity is a key indicator of prognosis for those with depression. Knowledge is limited on how best to encompass severity of disorders. A number of non-severity related factors such as social support and life events are also indicators of prognosis. It is not clear whether this holds true after adjusting for pre-treatment severity as a) a depressive symptom scale score, and b) a broader construct encompassing symptom severity and related indicators: "disorder severity". In order to investigate this, data from the individual participants of clinical trials which have measured a breadth of "disorder severity" related factors are needed. Aims: 1) To assess the association between outcomes for adults seeking treatment for depression and the severity of depression pre-treatment, considered both as i) depressive symptom severity only and ii) "disorder severity" which includes depressive symptom severity and comorbid anxiety, chronicity, history of depression, history of previous treatment, functional impairment and health-related quality of life. 2) To determine whether i) social support, ii) life events, iii) alcohol misuse, and iv) demographic factors (sex, age, ethnicity, marital status, employment status, level of educational attainment, and financial wellbeing) are prognostic indicators of outcomes, independent of baseline "disorder severity" and the type of treatment received. Methods: Databases were searched for randomised clinical trials (RCTs) that recruited adults seeking treatment for depression from their general practitioners and used the same diagnostic and screening instrument to measure severity at baseline - the Revised Clinical Interview Schedule; outcome measures could differ between studies. Chief investigators of all studies meeting inclusion criteria were contacted and individual patient data (IPD) were requested. Conclusions: In total 15 RCTs met inclusion criteria. The Dep-GP database will include the 6271 participants from the 13 studies that provided IPD. This protocol outlines how these data will be analysed.

Epidemiology of Mental Health Attendances at Emergency Departments: Systematic Review and Meta-Analysis.

BACKGROUND: The characteristics of Emergency Department (ED) attendances due to mental or behavioural health disorders need to be described to enable appropriate development of services. We aimed to describe the epidemiology of mental health-related ED attendances within health care systems free at the point of access, including clinical reason for presentation, previous service use, and patient sociodemographic characteristics. METHOD: Systematic review and meta-analysis of observational studies describing ED attendances by patients with common mental health conditions. FINDINGS: 18 studies from seven countries met eligibility criteria. Patients attending due to mental or behavioural health disorders accounted for 4% of ED attendances; a third were due to self-harm or suicidal ideation. 58.1% of attendees had a history of psychiatric illness and up to 58% were admitted. The majority of studies were single site and of low quality so results must be interpreted cautiously. CONCLUSIONS: Prevalence studies of mental health-related ED attendances are required to enable the development of services to meet specific needs.

Can non-pharmacological interventions prevent relapse in adults who have recovered from depression? A systematic review and meta-analysis of randomised controlled trials.

OBJECTIVE: To identify studies of non-pharmacological interventions provided following recovery from depression, and to evaluate their efficacy in preventing further episodes. METHOD: We identified relevant randomised controlled trials from searching MEDLINE, Embase, PsycINFO, CENTRAL, and ProQuest, searching reference and citation lists, and contacting study authors. We conducted a meta-analysis of relapse outcomes. RESULTS: There were 29 eligible trials. 27 two-way comparisons including 2742 participants were included in the primary analysis. At 12months cognitive-behavioural therapy (CBT), mindfulness-based cognitive therapy (MBCT), and interpersonal psychotherapy (IPT) were associated with a 22% reduction in relapse compared with controls (95% CI 15% to 29%). The effect was maintained at 24months for CBT, but not for IPT despite ongoing sessions. There were no 24-month MBCT data. A key area of heterogeneity differentiating these groups was prior acute treatment. Other psychological therapies and service-level programmes varied in efficacy. CONCLUSION AND IMPLICATIONS: Psychological interventions may prolong the recovery a person has achieved through use of medication or acute psychological therapy. Although there was evidence that MBCT is effective, it was largely tested following medication, so its efficacy following psychological interventions is less clear. IPT was only tested following acute IPT. Further exploration of sequencing of interventions is needed. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO 2011:CRD42011001646.

The direct and indirect economic costs incurred by living kidney donors-a systematic review.

BACKGROUND: Despite the many benefits of living donor kidney transplantation, economic consequences can result for donors. We reviewed studies which quantified the direct and indirect costs incurred by living kidney donors, in order to understand the strengths and limitations of existing literature. METHODS: We identified relevant studies in MEDLINE, EMBASE and ECONOLIT bibliographic databases, in the Science Citation Index and study reference lists. Any study which reported at least one cost relevant to donors was included. The accuracy of abstracted data was verified by two reviewers and reported in year 2004 US dollars. RESULTS: Thirty-five studies from 12 countries described costs incurred by individuals who donated between the years 1964 and 2003. No study comprehensively quantified all relevant expenses-the sum of select costs considered in one US study averaged Dollars 837 per donor and ranged from Dollars 0 to 28,906. Travel and/or accommodation costs were incurred by 9-99% of donors, and were higher in countries with a larger land mass. Post-discharge analgesics were required by 4-24% of donors, but prescription costs were not reported. Between 14 and 30% of donors incurred costs for lost income, with an average loss of Dollars 3386 in one study from the UK and Dollars 682 in another study from the Netherlands. Costs for dependent care were incurred by 9-44% of donors, while costs for domestic help were incurred by 8% of donors. CONCLUSIONS: Donors incur many types of costs attributable to kidney donation and the total costs are certainly higher than previously reported. To guide informed consent and fair reimbursement policies, further data on all relevant costs, preferably from a detailed prospective multi-centre cohort study, are required.
