RESUMO

The onset of the COVID-19 pandemic saw a significant surge in the utilization of telemental health (TMH) services. This narrative review aimed to investigate the efficacy of TMH for serious mood disorders prior to the COVID-19 pandemic. A search across databases was conducted for randomized controlled trials focusing on TMH interventions for mood disorders, encompassing major depressive disorder (MDD) and bipolar disorder (BD). Study and patient characteristics, interventions, and outcomes were extracted. From a pool of 2611 papers initially identified, 17 met the inclusion criteria: 14 focused on MDD, while 4 addressed BD. Among these, 6 papers directly compared TMH interventions to in-person of same treatment, revealing improved access to care and higher rates of appointment follow-up with TMH. Additionally, 6 papers comparing TMH to treatment as usual demonstrated improvements in mood outcomes. Conversely, 3 papers comparing different TMH interventions found no discernible differences in outcomes. Notably, 3 studies evaluated TMH as an adjunct to usual care, all reporting enhancements in depression outcomes. Overall, preliminary evidence suggests that prior to COVID-19, TMH interventions for serious mood disorders facilitated improved access to care and follow-up, with comparable clinical outcomes to traditional in-person interventions. The discussion addresses limitations and provides recommendations for future research in this domain.

RESUMO

The power and scope of disease modeling can be markedly enhanced through the incorporation of broad genetic diversity. The introduction of pathogenic mutations into a single inbred mouse strain sometimes fails to mimic human disease. We describe a cross-species precision disease modeling platform that exploits mouse genetic diversity to bridge cell-based modeling with whole organism analysis. We developed a universal protocol that permitted robust and reproducible neural differentiation of genetically diverse human and mouse pluripotent stem cell lines and then carried out a proof-of-concept study of the neurodevelopmental gene DYRK1A. Results in vitro reliably predicted the effects of genetic background on Dyrk1a loss-of-function phenotypes in vivo. Transcriptomic comparison of responsive and unresponsive strains identified molecular pathways conferring sensitivity or resilience to Dyrk1a1A loss and highlighted differential messenger RNA isoform usage as an important determinant of response. This cross-species strategy provides a powerful tool in the functional analysis of candidate disease variants identified through human genetic studies.

RESUMO

The study set out to perform a systematic literature review of evidence-based interventions that target the reduction of secondary stroke risk in Africa. The review analyzed longitudinal intervention studies conducted in Sub-Saharan Africa, focusing on adult participants who had suffered a prior stroke. It encompassed publications and peer-reviewed papers sourced from reputable databases, including PubMed, Ovid, Cochrane, and Web of Science. Three randomized clinical trial (RCT) studies were included with sample sizes ranging from 16 to 400 participants, mean age ranged between 50 and 66 years, with 64.5% male participants. All studies applied multidisciplinary team interventions of enhanced patient follow-up involving care givers, nurse educators, physicians, and social workers. Interventions ranged from comprehensive patient education, tracking of medication adherence and enforcing healthy lifestyle behaviors (regular exercise, regular BP checks, and dietary changes). We found a decrease in Systolic Blood Pressure over time in 2 of 3 treatment groups, an improvement in medical adherence in all treatment groups, and a decrease in cholesterol levels in 1 treatment group. Evidence-based interventions involving multidisciplinary teams and comprehensive patient education were found to demonstrate promising results in reducing secondary stroke risk in Africa, leading to significant improvements in medical adherence and reductions in systolic blood pressure in the majority of treatment groups. However, more research is required to confirm the influence of these interventions on cholesterol levels and to establish their lasting advantages in preventing strokes among African communities.

RESUMO

OBJECTIVE: The study objective was to characterize preoperative and postoperative continuous electroencephalogram metrics and hemodynamic adverse events as predictors of neurodevelopment in congenital heart disease infants undergoing cardiac surgery. METHODS: From 2010 to 2021, 320 infants underwent congenital heart disease surgery at our institution, of whom 217 had perioperative continuous electroencephalogram monitoring and were included in our study. Neurodevelopment was assessed in 76 patients by the Bayley Scales of Infant and Toddler Development, 3rd edition, consisting of cognitive, communication, and motor scaled scores. Patient and procedural factors, including hemodynamic adverse events, were included by means of the likelihood of covariate selection in our predictive model. Median (25th, 75th percentile) follow-up was 1.03 (0.09, 3.44) years with 3 (1, 6) Bayley Scales of Infant and Toddler Development, 3rd Edition evaluations per patient. RESULTS: Median age at index surgery was 7 (4, 23) days, and 81 (37%) were female. Epileptiform discharges, encephalopathy, and abnormality (lethargy and coma) were more prevalent on postoperative continuous electroencephalograms, compared with preoperative continuous electroencephalograms (P < .005). In 76 patients with Bayley Scales of Infant and Toddler Development, 3rd edition evaluations, patients with diffuse abnormality (P = .009), waveform discontinuity (P = .007), and lack of continuity (P = .037) on preoperative continuous electroencephalogram had lower cognitive scores. Patients with synchrony (P < .005) on preoperative and waveform continuity (P = .009) on postoperative continuous electroencephalogram had higher fine motor scores. Patients with postoperative adverse events had lower cognitive (P < .005) and gross motor scores (P < .005). CONCLUSIONS: Phenotypic patterns of perioperative continuous electroencephalogram metrics are associated with late-term neurologic injury in infants with congenital heart disease requiring surgery. Continuous electroencephalogram metrics can be integrated with hemodynamic adverse events in a predictive algorithm for neurologic impairment.

RESUMO

Timely repair of chromosomal double-strand breaks is required for genome integrity and cellular viability. The polymerase theta-mediated end joining pathway has an important role in resolving these breaks and is essential in cancers defective in other DNA repair pathways, thus making it an emerging therapeutic target1. It requires annealing of 2-6 nucleotides of complementary sequence, microhomologies, that are adjacent to the broken ends, followed by initiation of end-bridging DNA synthesis by polymerase θ. However, the other pathway steps remain inadequately defined, and the enzymes required for them are unknown. Here we demonstrate requirements for exonucleolytic digestion of unpaired 3' tails before polymerase θ can initiate synthesis, then a switch to a more accurate, processive and strand-displacing polymerase to complete repair. We show the replicative polymerase, polymerase δ, is required for both steps; its 3' to 5' exonuclease activity for flap trimming, then its polymerase activity for extension and completion of repair. The enzymatic steps that are essential and specific to this pathway are mediated by two separate, sequential engagements of the two polymerases. The requisite coupling of these steps together is likely to be facilitated by physical association of the two polymerases. This pairing of polymerase δ with a polymerase capable of end-bridging synthesis, polymerase θ, may help to explain why the normally high-fidelity polymerase δ participates in genome destabilizing processes such as mitotic DNA synthesis2 and microhomology-mediated break-induced replication3.

RESUMO

There is growing concern about the availability of healthcare services for rural patients. This systematic literature review evaluates original research on health disparities among rural and urban populations with mental health conditions in North America. Using PRISMA guidelines, we used four electronic databases (Pubmed, Cochrane, PsychInfo, Web of Science) and hand searches and included original research conducted in the United States or Canada before July 2021 that compared health outcomes of patients with any mental health disorder in rural versus non-rural areas. Both qualitative and quantitative data were extracted including demographics, mental health condition, health disparity measure, rural definition, health outcome measures/main findings, and delivery method. To evaluate study quality, the modified Newcastle Ottawa Scale was used. Our initial search returned 491 studies and 17 studies met final inclusion criteria. Mental health disorders included schizophrenia (4 studies), PTSD (10), mood disorders (9), and anxiety disorders (6). Total sample size was 5,314,818 with the majority being military veterans. Six studies (35.2%) showed no significant rural-urban disparities while eleven (64.7%) identified at least one. Of those, nine reported worse outcomes for rural patients. The most common disparities were diagnostic differences, increased suicide rates and access problems. This review found mixed results regarding outcomes in rural patients with mental health disorders. Disparities were found regarding risk of suicide and access to services. Telehealth in addition to in person outreach to these rural communities may be alternatives to impact these outcomes.

RESUMO

Introduction: Given the increasing use of telepsychiatry and to serve as a reference point informing future research, our team evaluated the literature on the use of telepsychiatry for medication adherence promotion prior to the COVID-19 pandemic among patients with psychotic disorders. Methods: A search of PubMed, Cochrane, Web of Science, CINAHL, and PsycINFO was conducted using PRISMA guidelines to identify telepsychiatry interventions to enhance medication adherence in patients with primary psychotic disorders. Both quantitative and qualitative data were extracted from the identified articles including study characteristics, interventions, and outcomes. Results: In total, 230 articles were obtained through electronic literature search, and 4 articles were eventually retained that met inclusion criteria. All 4 articles were randomized controlled trials, were adjuncts to in-person usual care, used telephone platforms and targeted medication adherence. Compared to treatment as usual, 3 out of 4 studies found medication adherence was improved and 2 out of 4 studies found improved medication attitudes. Telepsychiatry appeared to be acceptable to patients with psychotic disorders. Discussion: In the pre-Covid-19 literature, telepsychiatry appears promising as an adjunct to usual care for increasing medication adherence among individuals with schizophrenia/schizoaffective disorder. However, given the limited number of papers and exclusive use on telephone-only to deliver telepsychiatry, additional research specific to telepsychiatry for patients with psychosis is needed.

RESUMO

OBJECTIVE: Mobile health tools are feasible options to encourage behavior change among patients with serious mental illness. Mobile health tools vary widely, both in platforms used and content delivered. This literature review assessed the use of text messaging interventions to promote medication adherence among patients with serious mental illness. METHODS: A systematic literature review using PRISMA guidelines examined short message service (SMS) text messaging interventions promoting medication adherence to people with a serious mental illness diagnosis. Databases included PubMed, Cochrane, CINAHL, and PsycINFO. Data extraction included demographic information, participant diagnoses, intervention components, medication class, adherence measures, research design, and study outcomes. Study quality was also assessed. RESULTS: Of 114 full-text articles screened, 10 articles were selected from nine unique interventions (N=937 people with serious mental illness). Study durations ranged from 30 days to 18 months, with frequency of SMS ranging from twice weekly to 12 times daily. Of the nine unique trials, most reported using an automated server to deliver SMS messages (N=7), two-way SMS capabilities (N=6), customized message content or timing (N=7), and additional components (e.g., provider contact, educational content, and monetary rewards) (N=7). Seven of the 10 articles reported statistically significant improvement in medication adherence and in at least one clinical outcome. CONCLUSIONS: Evidence to date indicates that text messaging interventions are feasible and appear to improve medication adherence and clinical outcomes among patients with serious mental illness. Future research should assess implementation approaches and how to scale up efforts in nonresearch settings.

RESUMO

Background: Centers of excellence (COEs) are interdisciplinary healthcare organizations created with the goal of improving health/economic outcomes in medical treatment for both individuals and health systems, compared to traditionally structured counterparts. Multiple studies have highlighted both societal/individual burdens associated with back pain, underscoring the importance of identifying new avenues for improving both cost/clinical outcomes for this patient population. Here, we utilize available literature to better characterize the features of a spine COE at a tertiary care center and determine the impact of COEs on patient satisfaction and outcomes. Methods: A systematic review describing spine COEs was performed. PubMed, OVID, Cochrane, Web of Science, and Scopus were utilized for electronic literature search. Data including institution, department, pathologies treated, patient satisfaction scores, patient outcomes, and descriptions of the COE, were extracted and analyzed by two reviewers per full-text article. Inclusion criteria consisted of literature describing the organization, purpose, or outcomes of a spine COE, all publication types (except technical/operative report), adult or pediatric patients, publication from inception through September 2021. Exclusion criteria consisted of articles that do not discuss spinal COEs, technical/operative reports, studies unavailable in English language, unavailable full text, or non-human subjects. The Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of the included studies. Results: Five hundred and sixty-seven unique publications were obtained from the literature search. Of these articles, 20 were included and 547 were excluded based on inclusion and exclusion criteria. Following full-text review of the 20 publications, 6 contained pertinent data. Quantitative data comparing COE versus non-COE was contradictory in comparing complication rates and episodic costs. Qualitative data included descriptions of spine COE features and cited improved patient care, technical advancements, and individualized care paths as positive aspects of the COE model. Mean risk of bias assessment was 3.67. Discussion: There is little evidence regarding if spine COEs provide an advantage over traditionally organized facilities. The current number and heterogeneity of publications, and lack of standardized metrics used to define a spinal COE are limiting factors. Spinal COE may offer higher value care, reduced complication rates and advancements in knowledge and technical skill.

RESUMO

Previous research has consistently demonstrated that regular exercise promotes antioxidant production and decreases the expression of inflammation markers. However, there is very little research examining the effects of intermittent fasting (IF) on oxidative stress and inflammation. The present study investigated the hypothesis that a combination of IF and physical activity will reduce the need for glutathione (GSH) production by decreasing oxidative stress. In addition, it was hypothesized that a combination of IF and physical activity will significantly reduce inflammation, as indicated by a decrease in interleukin-1ß (IL-1ß) concentration. For three months, subjects practicing IF (n=7) ate only during an eight-hour window each day and fasted for the next 16 hours. A standard diet control group (n=18) maintained a normal, balanced diet spread out over the course of 14-18 hours each day. Based on data obtained from fitness-tracking devices, subjects were placed into one of three activity level groups: minimum, moderate, and maximum physical activity. Subjects provided fasting saliva samples monthly. The samples were subjected to a glutathione microplate assay and an interleukin ELISA test to determine salivary concentrations of GSH and IL-1ß, respectively. For GSH concentration, there were no significant differences between the diets at any physical activity level. However, moderate to maximum physical activity, in conjunction with fasting, led to significant decreases in IL-1ß concentration. In summary, results suggest that a combination of moderate physical activity and intermittent fasting promotes the maintenance of antioxidant function while inhibiting the inflammatory process.

RESUMO

The retinoic acid receptors (RARs or rars) and the thyroid hormone receptors are members of the steroid receptor superfamily that interact with their DNA response elements (for RARs: retinoic acid response elements or RAREs) in the regulatory regions of promoters in the absence of their ligand. In this ligand minus configuration, it has been suggested that the RAR provides a binding site for a corepressor (SMRT or N-CoR) that also brings in other proteins to repress the gene. In the presence of the ligand, the receptor goes through an allosteric change eliminating the corepressor binding site and providing a coactivator binding site. In this manuscript we describe the isolation of the zebrafish corepressor, smrt. We show that its association with the zebrafish rar aa is sensitive to retinoic acid and that the corepressor mRNA is present in 8 cell zebrafish embryos - a time at which the embryonic genome is not active. We suggest that this rar-corepressor complex may be part of an embryonic, epigenetic switch that keeps retinoic acid responsive genes off before retinoic becomes available to the embryo.
