RESUMO

BACKGROUND: Celiac Disease (CD) is associated with increased susceptibility to certain bacterial and viral infections. Herpes zoster (HZ) is a viral infection that can be prevented by immunization. In the US, the vaccine is recommended for adults ≥ 50 or ≥ 19 with certain at-risk conditions, not including CD. AIMS: We aimed to determine if adult patients aged < 50 or ≥ 50 years with CD had a higher risk of developing HZ. METHODS: We designed a retrospective cohort study. CD was defined as patients with the ICD-10 code for CD and positive Celiac serology. Patients with negative serology and lacking CD ICD-10 codes served as controls. Patients who had HZ before CD diagnosis were excluded. We formed two sub-cohorts, those aged < 50 (cohort 1) and aged ≥ 50 years (cohort 2), and evaluated HZ infection at 10-year follow-up. To account for confounding variables, we performed 1:1 propensity score matching (PSM). RESULTS: Following PSM, cohort 1 had 6,826 CD patients, and cohort 2 had 5,337 CD patients and respective matched controls. After ten years of follow-up, in cohort 1, 62 CD patients developed HZ versus 57 controls, RR: 1.09 (CI: 0.76-1.56, p-value = 0.64). In cohort 2, 200 CD patients developed HZ versus 159 controls, RR: 1.2 (CI: 1.02-1.54, p-value = 0.03). CONCLUSION: There was no significant difference in the likelihood of getting HZ in CD patients < 50, although CD patients ≥ 50 had a modestly increased risk. Our findings do not support routine early vaccination for HZ in CD, and the vaccine should be offered at age 50.

RESUMO

BACKGROUND AND AIMS: Dedicated multidisciplinary programs in gastroenterology are emerging with the goal to improve care. There is little information about the effects of a celiac disease program on disease-related quality care metrics and outcomes. We aimed to compare quality care metrics, symptom resolution, and serological response among patients diagnosed and treated in a celiac disease program with a standard of care cohort. METHODS: We performed a retrospective cohort study with adult celiac disease patients. We divided patients into two groups: celiac disease patients treated in our program and those treated by gastroenterologists not affiliated with the program (standard of care). We abstracted data from electronical medical records and compared frequency at which guideline-driven quality care metrics were obtained, assessed symptom resolution, and serological response based on IgA anti-tissue transglutaminase levels. RESULTS: We included 340 patients, 120 in the celiac disease program (89 women) and 220 (166 women) in the standard of care. Frequency of quality care metrics implementation in program patients was significantly greater for all variables (p < 0.0005). Diarrhea resolved in 38/46 (82.6%) in the CD program and 63/98 (64.2%) in the standard of care after starting a gluten-free diet (p = .025); bloating also resolved significantly more often in the former (26/34) than the latter (31/58; p = 0.03). Otherwise, there were no significant differences in resolution of clinical symptoms or serological response. CONCLUSION: A celiac disease program improves celiac-related quality care metrics and may improve outcomes such as diarrhea resolution compared to standard of care.

RESUMO

OBJECTIVES: Some studies have suggested a link between celiac disease (CD) and adverse maternal, obstetrical, and neonatal outcomes. Using a large database, we evaluated the effect of CD on pregnancy outcomes. METHODS: We conducted a retrospective cohort study using the National Inpatient Sample (NIS) of all deliveries from 2015 to 2019 in the United States. Using ICD-10 codes, we identified pregnant patients who had CD and those who did not. A multivariate logistic regression was used to generate odds ratios (ORs) with 95% confidence intervals (CIs) for maternal, obstetrical, and neonatal outcomes. RESULTS: Of 12,039,222 deliveries between 2015 and 2019, there were 10,555 births in women with CD. Pregnant women with CD were more likely to be white and older compared to those without CD. Pregnant women with CD were significantly more likely to carry a diagnosis of gestational hypertension (OR 1.26; 95% CI 1.04-1.52), preeclampsia (1.28; 1.08-1.53), and severe preeclampsia (1.62; 1.25-2.09). They were less likely to have a full-term uncomplicated delivery (OR 0.11; 95% CI, 0.05-0.20), while being more likely to require device-assisted delivery (1.25; 1.04-1.50) and sustain 3rd or 4th degree vaginal lacerations (1.56; 1.21-2.02). Babies of pregnant women with CD were more likely to be small for gestational age (SGA) (OR 1.29; 95% CI 1.03-1.61). CONCLUSIONS: CD in pregnancy appears to be associated with increased adverse maternal, obstetrical, and neonatal outcomes. Clinicians should discuss these increased risks with CD patients who are planning to conceive.

RESUMO

The 2021 Global Vaccine and Immunization Research Forum highlighted the considerable advances and recent progress in research and development for vaccines and immunization, critically reviewed lessons learned from COVID-19 vaccine programs, and looked ahead to opportunities for this decade. For COVID-19, decades of investments in basic and translational research, new technology platforms, and vaccines targeting prototype pathogens enabled a rapid, global response. Unprecedented global coordination and partnership have played an essential role in creating and delivering COVID-19 vaccines. More improvement is needed in product attributes such as deliverability, and in equitable access to vaccines. Developments in other priority areas included: the halting of two human immunodeficiency virus vaccine trials due to lack of efficacy in preventing infection; promising efficacy results in Phase 2 trials of two tuberculosis vaccines; pilot implementation of the most advanced malaria vaccine candidate in three countries; trials of human papillomavirus vaccines given in single-dose regimens; and emergency use listing of a novel, oral poliomyelitis type 2 vaccine. More systematic, proactive approaches are being developed for fostering vaccine uptake and demand, aligning on priorities for investment by the public and private sectors, and accelerating policy making. Participants emphasized that addressing endemic disease is intertwined with emergency preparedness and pandemic response, so that advances in one area create opportunities in the other. In this decade, advances made in response to the COVID-19 pandemic should accelerate availability of vaccines for other diseases, contribute to preparedness for future pandemics, and help to achieve impact and equity under Immunization Agenda 2030.

RESUMO

BACKGROUND: We sought to describe clinical characteristics of celiac disease (CD) patients infected with coronavirus disease 2019 (COVID-19) and estimate hospitalization risk, intensive care unit (ICU) requirement, mortality, and thrombosis, and the impact of vaccination on these outcomes. METHODS: We performed a single-center, retrospective cohort study comparing biopsy-proven CD patients with a matched sample of non-CD (referent) patients diagnosed with COVID-19 between March 2020 and January 2022. Matching ensured 2 referent patients for every 1 CD patient by age, sex, ethnicity, and COVID-19 diagnosis date. We also adjusted for general and celiac-specific comorbidity. The primary outcome was hospitalization. Secondary outcomes included ICU requirement, mortality, and thrombosis. We also compared these outcomes between vaccinated and unvaccinated individuals. RESULTS: We included 330 patients: 110 with CD (mean age 47 years, 83% female) and 220 matched referents. Hospitalization occurred in 27 CD patients (24%) and 25 referent patients (11%) (hazard ratio, 2.10; 95% confidence interval, 1.21-3.65; P = .009). Vaccination was associated with significantly decreased risk of hospitalization (hazard ratio, 0.53; 95% confidence interval, 0.31-0.93; P = .026). Four unvaccinated CD patients and 2 unvaccinated referent patients required ICU. No mortality occurred among CD patients, and 2 referent patients died. No thrombosis occurred in either group. CONCLUSIONS: CD patients with COVID-19 have a higher risk of hospitalization compared with non-CD referents. This risk is mitigated by vaccination in CD patients as it is in non-CD referents. ICU requirement occurred only in unvaccinated CD patients, and no CD patient died. Vaccination against COVID-19 should be strongly recommended in patients with CD as it is for non-CD patients in the general population.

RESUMO

Research and innovation have been fundamental to many of the successes in immunization thus far, and will play important roles in the future success of Immunization Agenda 2030 (IA2030). Strategic Priority 7 (SP7) of IA2030, which addresses research and innovation, is explicitly informed by country needs and priorities, and aims to strengthen the innovation ecosystem through capacity building and collaboration at country, regional, and global levels. SP7 identifies four key focus areas: (1) "needs-based innovation", (2) "new and improved products, services, and practices", (3) "evidence for implementation", and (4) "local capacity". Strategic interventions in these key focus areas apply the lessons of the Global Vaccine Action Plan and the "Decade of Vaccines" to emphasize local innovation, promote the use of research by countries to improve program performance and impact, and encourage capacity building for the development and implementation of innovations. The proposed approach will maintain a focus on the development of new vaccines and the improvement of existing vaccines, and increase attention to innovation in service delivery. Monitoring and evaluation will foster evidence-based priority setting at the country level and help to ground the global research and development (R&D) agenda in the needs of communities. Together, these approaches are intended to harness the power of research and innovation more effectively, to meet the challenges of the future and achieve the ambitious goals of IA2030.

RESUMO

We investigated the cumulative prevalence of self-harm ideation among stroke survivors of the AFFINITY trial. We assessed these thoughts with the last item of the PHQ-9, and functional impairment with the modified Rankin Scale (mRS). Of 1221 participants (age 63.9 ± 12.3 years, 775 men), 11 reported wishing to die or self-harm at baseline. By week 52, 36 of 1159 surviving participants had reported wishing to die or self-harm. Treatment with fluoxetine for 26 weeks did not change the prevalence of these thoughts compared with placebo. Clinically significant symptoms of depression were present in 95 % of participants with recurrent self-harm thoughts. The study was registered with the Australian and New Zealand Clinical Trials Registry, ACTRN12611000774921.

RESUMO

Species radiations, despite immense phenotypic variation, can be difficult to resolve phylogenetically when genetic change poorly matches the rapidity of diversification. Genomic potential furnished by palaeopolyploidy, and relative roles for adaptation, random drift and hybridisation in the apportionment of genetic variation, remain poorly understood factors. Here, we study these aspects in a model radiation, Syzygium, the most species-rich tree genus worldwide. Genomes of 182 distinct species and 58 unidentified taxa are compared against a chromosome-level reference genome of the sea apple, Syzygium grande. We show that while Syzygium shares an ancient genome doubling event with other Myrtales, little evidence exists for recent polyploidy events. Phylogenomics confirms that Syzygium originated in Australia-New Guinea and diversified in multiple migrations, eastward to the Pacific and westward to India and Africa, in bursts of speciation visible as poorly resolved branches on phylogenies. Furthermore, some sublineages demonstrate genomic clines that recapitulate cladogenetic events, suggesting that stepwise geographic speciation, a neutral process, has been important in Syzygium diversification.

RESUMO

BACKGROUND: Lithium has neuroprotective effects in animal models of stroke, but benefits in humans remain uncertain. This article aims to systematically review the available evidence of the neuroprotective and regenerative effects of lithium in animal models of stroke, as well as in observational and trial stroke studies in humans. METHODS: This systematic review and meta-analysis was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched Medline, Embase, and PsycINFO for preclinical and clinical studies published between January 2000 and September 2021. A random-effects meta-analysis was conducted from observational studies. RESULTS: From 1625 retrieved studies, 42 were included in the systematic review. Of those, we identified 36 rodent models of stroke using preinsult or postinsult treatment with lithium, and 6 studies were conducted in human samples, of which 4 could be meta-analyzed. The review of animal models was stratified according to the type of stroke and outcomes. Human data were subdivided into observational and intervention studies. Treatment of rodents with lithium was associated with smaller stroke volumes, decreased apoptosis, and improved poststroke function. In humans, exposure to lithium was associated with a lower risk of stroke among adults with bipolar disorder in 2 of 4 studies. Two small trials showed equivocal clinical benefits of lithium poststroke. CONCLUSIONS: Animal models of stroke show consistent biological and functional evidence of benefits associated with lithium treatment, whereas human evidence remains sparse and inconclusive. The potential role of lithium in poststroke recovery is yet to be adequately tested in humans.

RESUMO

Background Function after acute stroke using the modified Rankin Scale (mRS) is usually assessed at a point in time. The analytical implications of serial mRS measurements to evaluate functional recovery over time is not completely understood. We compare repeated-measures and single-measure analyses of the mRS from a randomized clinical trial. Methods and Results Serial mRS data from AFFINITY (Assessment of Fluoxetine in Stroke Recovery), a double-blind placebo randomized clinical trial of fluoxetine following stroke (n=1280) were analyzed to identify demographic and clinical associations with functional recovery (reduction in mRS) over 12 months. Associations were identified using single-measure (day 365) and repeated-measures (days 28, 90, 180, and 365) partial proportional odds logistic regression. Ninety-five percent of participants experienced a reduction in mRS after 12 months. Functional recovery was associated with age at stroke <70 years; no prestroke history of diabetes, coronary heart disease, or ischemic stroke; prestroke history of depression, a relationship partner, living with others, independence, or paid employment; no fluoxetine intervention; ischemic stroke (compared with hemorrhagic); stroke treatment in Vietnam (compared with Australia or New Zealand); longer time since current stroke; and lower baseline National Institutes of Health Stroke Scale & Patient Health Questionnaire-9 scores. Direction of associations was largely concordant between single-measure and repeated-measures models. Association strength and variance was generally smaller in the repeated-measures model compared with the single-measure model. Conclusions Repeated-measures may improve trial precision in identifying trial associations and effects. Further repeated-measures stroke analyses are required to prove methodological value.

RESUMO

OBJECTIVES: To determine if behavioral activation (BA) delivered by trained staff decreases prevalence of clinically significant symptoms of depression among older adults living in residential aged care facilities (RACFs). METHODS: Clustered, randomized, single-blinded, controlled trial of BA for adults aged over 60 years living permanently in a RACF with symptoms of depression (Patient Health Questionnaire, PHQ-9 ≥ 5). BA was delivered over 8-12 weeks using a structured workbook. The proportion of residents with PHQ-9 ≥ 10 at weeks 12, 26, and 52, as well as anxiety symptoms (GAD-7), physical (PCS), and mental (MCS) quality of life, loneliness, and loss to follow-up were main outcomes of interest RESULTS: We recruited 54 RACFs (26 intervention) and 188 of their residents (89 intervention). Participants were aged 61-100 years and 132 (70.2%) were women. PHQ-9 ≥ 10 interacted with BA at week 12 (OR = 0.34, 95%CI = 0.11-1.07), but differences between the groups were not statistically significant at any time-point. GAD-7 ≥ 10 interacted with BA at week 26 (OR = 0.12, 95%CI = 0.02-0.58), but not at any other time-point. Overall, the intervention had no effect on the scores of the PHQ-9, GAD-7, PCS, MCS, and loneliness scale. Loss to follow-up was similar between groups. Adherence to all stages of the intervention was poor (36.2%). CONCLUSIONS: Disruption by the COVID-19 pandemic and staffing issues in RACFs undermined recruitment and adherence. In such a context, a BA program delivered by RACF staff was not associated with better mental health outcomes for residents over 52 weeks.

RESUMO

Over millennia, Indigenous peoples have dispersed the propagules of non-crop plants through trade, seasonal migration or attending ceremonies; and potentially increased the geographic range or abundance of many food species around the world. Genomic data can be used to reconstruct these histories. However, it can be difficult to disentangle anthropogenic from non-anthropogenic dispersal in long-lived non-crop species. We developed a genomic workflow that can be used to screen out species that show patterns consistent with faunal dispersal or long-term isolation, and identify species that carry dispersal signals of putative human influence. We used genotyping-by-sequencing (DArTseq) and whole-plastid sequencing (SKIMseq) to identify nuclear and chloroplast Single Nucleotide Polymorphisms in east Australian rainforest trees (4 families, 7 genera, 15 species) with large (>30 mm) or small (<30 mm) edible fruit, either with or without a known history of use by Indigenous peoples. We employed standard population genetic analyses to test for four signals of dispersal using a limited and opportunistically acquired sample scheme. We expected different patterns for species that fall into one of three broadly described dispersal histories: (1) ongoing faunal dispersal, (2) post-megafauna isolation and (3) post-megafauna isolation followed by dispersal of putative human influence. We identified five large-fruited species that displayed strong population structure combined with signals of dispersal. We propose coalescent methods to investigate whether these genomic signals can be attributed to post-megafauna isolation and dispersal by Indigenous peoples.

RESUMO

BACKGROUND: Recently, the Cirrhotic Cardiomyopathy Consortium (Consortium) proposed criteria to replace the World Congress of Gastroenterology (WGO) criteria for cirrhotic cardiomyopathy (CCM) using contemporary echocardiography parameters. We assessed the impact of substituting WGO by Consortium criteria on the frequency of diagnosis and clinical outcomes in patients with cirrhosis awaiting liver transplantation (LT). METHODS: Consecutive adults with cirrhosis approved for LT with echocardiography evaluation from January 2014 to December 2016 were screened. Patients with structural heart diseases were excluded. Two primary outcomes were: (1) frequency of CCM; (2) association of CCM with pre-transplant mortality. The secondary outcomes were pre-LT complications of acute kidney injury (AKI) and/or hepatic encephalopathy (HE), and post-LT mortality. RESULTS: Of 386 patients screened, 278 were included. 238 (85.6%) and 208 (74.8%) patients met Consortium and WGO criteria, respectively; 180 (64.7%) patients fulfilled both the criteria, while 12 (4.3%) patients had no evidence of CCM by either criterion. Pre-LT mortality rates in Consortium-CCM group were similar to the other groups (19.3% vs 20.2% vs 25.0%). The patients with advanced diastolic dysfunction (DD) per Consortium-CCM criteria had higher mortality than the other groups. The rates of pre-LT AKI/HE rates and post-LT mortality were similar in Consortium-CCM and WGO-CCM groups. CONCLUSION: The Consortium criteria do not impact the prevalence of CCM compared to WGO criteria and have similar predictive accuracy. Presence of advanced DD per the Consortium criteria increases the risk of pre-LT mortality and complications of AKI/HE. The patients with advanced DD could benefit from further monitoring and treatment.

RESUMO

PURPOSE: Delirium is common in the critically ill, highly distressing to patients and families and associated with increased morbidity and mortality. Results of studies on preventative use of melatonin in various patient groups have produced mixed results. The aim of this study was to determine whether administration of melatonin decreases the prevalence of delirium in critically ill patients. METHODS: Multicentre, randomized, placebo-controlled, double-blind trial across 12 Australian ICUs recruiting patients from July 2016 to September 2019. Patients of at least 18 years requiring ICU admission with an expected length of stay (LOS) greater than 72 h; enrolled within 48 h of ICU admission. Indistinguishable liquid melatonin (4 mg; n = 419) or placebo (n = 422) was administered enterally at 21:00 h for 14 consecutive nights or until ICU discharge. The primary outcome was the proportion of delirium-free assessments, as a marker of delirium prevalence, within 14 days or before ICU discharge. Delirium was assessed twice daily using the Confusion Assessment Method for ICU (CAM-ICU) score. Secondary outcomes included sleep quality and quantity, hospital and ICU LOS, and hospital and 90-day mortality. RESULTS: A total of 847 patients were randomized into the study with 841 included in data analysis. Baseline characteristics of the participants were similar. There was no significant difference in the average proportion of delirium-free assessments per patient between the melatonin and placebo groups (79.2 vs 80% respectively, p = 0.547). There was no significant difference in any secondary outcomes including ICU LOS (median: 5 vs 5 days, p = 0.135), hospital LOS (median: 14 vs 12 days, p = 0816), mortality at any time point including at 90 days (15.5 vs 15.6% p = 0.948), nor in the quantity or quality of sleep. There were no serious adverse events reported in either group. CONCLUSION: Enteral melatonin initiated within 48 h of ICU admission did not reduce the prevalence of delirium compared to placebo. These findings do not support the routine early use of melatonin in the critically ill.

RESUMO

BACKGROUND AND OBJECTIVES: To determine the sociodemographic and clinical factors associated with early, late, and persistent clinically significant symptoms of depression during the first year after a stroke. METHODS: This cohort study included 1,221 men and women recruited within 2 weeks of stroke onset in Australia, New Zealand, and Vietnam. The NIH Stroke Scale (NIHSS) was used to assess stroke severity. Other study measures included age, sex, marital status, living arrangements, function before the stroke, depression before the stroke, modified Rankin Scale (mRS) score, and treatment with fluoxetine or placebo for 26 weeks. Clinically significant symptoms of depression during the 52 weeks after baseline was the outcome of interest, and the presence of depression was defined by a total Patient Health Questionnaire (PHQ-9) score of ≥9 at week 4, 12, 26, or 52; a clinician diagnosis of depression between assessments; or pharmacologic or psychological treatment of depression during follow-up. Participants were classified as not depressed or as having early (initial 12 weeks), late (12-52 weeks), or persistent (before and after 12 weeks) depression. We used multinomial logistic regression to assess depression risk, with all listed measures entered simultaneously into the model. RESULTS: The mean age of participants was 63.8 (SD 12.3) years, and 775 (63.5%) were male. At baseline, 48 (3.9%) participants had previous treated depression, and 228 (18.7%) had clinically significant symptoms of depression (PHQ-9 score ≥9). Seven hundred thirty-four (63.3%) participants showed no evidence of depression in the year after the stroke; 208 (17.9%) had early, 86 (7.4%) had late, and 131 (11.3%) had persistent depression. Increased stroke severity, as measured by doubling of the NIHSS scores, was associated with an increased risk of early (risk ratio [RR] 2.08, 95% CI 1.65-2.62), late (RR 1.53, 95% CI 1.14-2.06), and persistent (RR = 2.50, 95% CI 1.89-3.32) clinically significant symptoms of depression. Similar findings were apparent for the mRS, a measure of functional disability. Past depression was associated with increased risk of persistent clinically significant symptoms of depression (RR = 6.28, 95% CI 2.88-13.71), as was being married or partnered (RR = 3.94, 95% CI 2.42-6.41). The risk of clinically significant symptoms of depression was higher in Australia and New Zealand than in Vietnam. DISCUSSION: The severity of neurologic and functional deficits increases the risk of poststroke clinically significant symptoms of depression early and persistently. Depression before stroke, personal relationships, and cultural context contribute to mediate depression risk. Interventions that minimize the severity of neurologic and functional deficits should decrease the risk of poststroke clinically significant symptoms of depression.

RESUMO

OBJECTIVE: To determine if hearing loss is associated with increased risk of frailty in later life. STUDY DESIGN: Cross-sectional study of a community sample of 4,004 men aged 70 years and above living in the metropolitan region of Perth, Western Australia. Data were retrieved from the Health in Men Study (HIMS) and the Western Australian Data Linkage System (WADLS). Frailty was assessed using the FRAIL scale and the Frailty Index. Hearing loss was defined by self-report or by diagnosis recorded in the WADLS. We also collected demographic, lifestyle and social support information. MAIN OUTCOME MEASURES: Frailty was assessed using the FRAIL scale and the Frailty Index. RESULTS: The prevalence of frailty in the sample population was 16.1% and 25.4% when assessed using the FRAIL scale and the Frailty Index respectively. After adjusting for participant demographic, lifestyle and social factors, hearing loss was significantly associated with the prevalence of frailty when diagnosed by either measure (FRAIL scale: odds ratio [OR] 1.59, 95 CI% 1.32 to 1.91; Frailty Index: OR 1.76, 95 CI% 1.50 to 2.05). The proportion of men with hearing loss increased with increasing severity of frailty. CONCLUSION: Hearing loss is associated with increased prevalence of frailty in older men when assessed using the FRAIL scale and the Frailty Index. Future longitudinal studies using objective measures of hearing will be helpful in determining if this association is likely to be causal.
