Increasing awareness of rare PSP-F, where rehabilitation is the primary treatment: A case report.

BACKGROUND: Progressive Supranuclear Palsy (PSP) is an incurable neurodegenerative disorder. One variant of PSP is a frontal lobe cognitive or behavioral presentation (PSP-F). Currently, the primary management of this disease is rooted in neurological rehabilitation, therefore, early, and accurate diagnosis is key. CASE REPORT: Here we present a 60-year-old man with a 2-3-year history of functional decline and behavioral changes. He was misdiagnosed with a late-onset psychiatric disorder. During his second inpatient admission, a full workup for neurodegenerative diseases was performed, and the patient was ultimately diagnosed with probable PSP-F. We describe his neurological rehabilitation plan, examining recommendations before and after diagnosis. RESULTS: After the neurodegenerative disorder diagnosis, the neurological rehabilitation plan, particularly PT and OT, changed drastically despite no change in clinical presentation emphasizing the value of an appropriate and early diagnosis. Furthermore, in an OT session, the patient demonstrated longitudinal improvement, emphasizing the importance of rehabilitation in these patient's lives. CONCLUSION: Increased recognition of PSP variants amongst healthcare providers will allow more patients to receive early and appropriate diagnoses, so that they can benefit maximally from their neurological rehabilitation plans, maintain quality of life and experience longer periods of functioning. Furthermore, developing PSP-specific rehabilitation guidelines are crucial for improved outcomes. Correct diagnosis will also reduce the use of inappropriate and potentially harmful medications in these populations.

Adaptation of Metabolomics and Microbiomic Research Protocols During the COVID-19 Pandemic.

BACKGROUND: When the COVID-19 pandemic hit in 2020, researchers in the P30 Center for the Study of Symptom Science, Metabolomics, and Multiple Chronic Conditions at Emory University's Nell Hodgson Woodruff School of Nursing faced major challenges in recruitment and data collection because of limited access to the clinic and community facilities and the risk of COVID-19 exposure associated with in-person study contact. OBJECTIVES: The purpose of this article is to (a) describe how a cadre of pilot/supplement principal investigators adapted their studies to allow for safe and trustworthy data collection during the COVID-19 pandemic (March 2020 through date of publication) and (b) discuss steps that facilitated the technical aspects of remote data collection, especially involving biological specimens. RESULTS: Four pilot studies and two administrative supplements within the center-all at different stages of execution-adopted various alternative remote recruitment, enrollment, and data and specimen collection approaches to continue their research endeavors in a way that maximized the safety of both the research participants and the research teams. DISCUSSION: The article concludes with a discussion on the importance of a participant-centered approach when using remote methods, actions, or steps initiated to facilitate the technical aspects of remote data collection and reflections on the continued use of remote research strategies beyond the COVID-19 pandemic.

Womb to womb: Maternal litter size and birth weight but not adult characteristics predict early neonatal death of offspring in the common marmoset monkey.

A singular focus on maternal health at the time of a pregnancy leaves much about perinatal mortality unexplained, especially when there is growing evidence for maternal early life effects. Further, lumping stillbirth and early neonatal death into a single category of perinatal mortality may obscure different causes and thus different avenues of screening and prevention. The common marmoset monkey (Callithrix jacchus), a litter-bearing nonhuman primate, is an ideal species in which to study the independent effects of a mother's early life and adult phenotypes on pregnancy outcomes. We tested two hypotheses in 59 marmoset pregnancies at the Southwest National Primate Research Center and the Barshop Institute for Longevity and Aging Studies. We explored 1) whether pregnancy outcomes were predicted independently by maternal adult weight versus maternal litter size and birth weight, and 2) whether stillbirth and early neonatal death were differentially predicted by maternal variables. No maternal characteristics predicted stillbirth and no maternal adult characteristics predicted early neonatal death. In univariate Poisson models, triplet-born females had a significantly increased rate of early neonatal death (IRR[se] = 3.00[1.29], p = 0.011), while higher birth weight females had a decreased rate (IRR[se] = 0.89[0.05], p = 0.039). In multivariate Poisson models, maternal litter size remained an independent predictor, explaining 13% of the variance in early neonatal death. We found that the later in the first week those neonates died, the more weight they lost. Together these findings suggest that triplet-born and low birth weight females have distinct developmental trajectories underlying greater rates of infant loss, losses that we suggest may be attributable to developmental disruption of infant feeding and carrying. Our findings of early life contributions to adult pregnancy outcomes in the common marmoset disrupt mother-blaming narratives of pregnancy outcomes in humans. These narratives hold that the pregnant person is solely responsible for pregnancy outcomes and the health of their children, independent of socioecological factors, a moralistic framing that has shaped clinical pregnancy management. It is necessary to differentiate temporal trajectories and causes of perinatal loss and view them as embedded in external processes to develop screening, diagnostic, and treatment tools that consider the full arc of a mother's lived experience, from womb to womb and beyond.

Sex-specific effects of in vitro fertilization on adult metabolic outcomes and hepatic transcriptome and proteome in mouse.

Although in vitro fertilization (IVF) is associated with adverse perinatal outcomes, there is increasing concern about the long-term and sex-specific health implications. Augmenting our IVF mouse model to longitudinally investigate metabolic outcomes in offspring from optimal neonatal litter sizes, we found sex-specific metabolic outcomes in IVF offspring. IVF-conceived females had higher body weight and cholesterol levels compared to naturally conceived females, whereas IVF-conceived males had higher levels of triglycerides and insulin, and increased body fat composition. Through adult liver transcriptomics and proteomics, we identified sexually dimorphic dysregulation of the sterol regulatory element-binding protein (SREBP) pathways that are associated with the sex-specific phenotypes. We also found that global loss of DNA methylation in placenta was linked to higher cholesterol levels in IVF-conceived females. Our findings indicate that IVF procedures have long-lasting sex-specific effects on metabolic health of offspring and lay the foundation to utilize the placenta as a predictor of long-term outcomes.

Treatment of Depression After Traumatic Brain Injury: A Systematic Review Focused on Pharmacological and Neuromodulatory Interventions.

BACKGROUND: Depression is the most common psychiatric sequela after traumatic brain injury (TBI) and poses a variety of treatment challenges. There is a lack of clinical trials focused on biological interventions used to manage TBI depression. OBJECTIVE: The aim of this systematic review is to summarize the current evidence of psychotropic and neuromodulatory interventions used to treat TBI depression and to provide directions for future research. METHODS: Key words were used to describe the following search terms: "traumatic brain injury", "depression", "pharmacological/drug therapy", and "neuromodulation". Studies focused on pharmacotherapy or neuromodulation in TBI depression were identified in 5 databases: Medline (PubMed), EMBASE (Embase.com), the Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), PsycINFO (EbscoHost), and Web of Science. Article inclusion/exclusion using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-based systematic protocol of extraction and evaluation was applied. Level of evidence for each study was determined using the American Academy of Neurology criteria. RESULTS: The initial search provided 1473 citations. Twenty-two studies met inclusion criteria. Sixteen studies explored pharmacological interventions with emphasis on serotonergic agents. Results between studies were conflicting, and interventions did not always outperform placebos, although sertraline provided the highest level of evidence for treatment of TBI depression. Six studies examining neuromodulatory interventions show preliminary evidence of efficacy with a range of interventions and modes of delivery used. CONCLUSIONS: Additional research including large-sample randomized-controlled trials using pharmacological, neuromodulation, or combination treatment is needed. These studies should incorporate premorbid psychosocial functioning, preinjury psychiatric disease, cognitive deficits, and functional recovery when examining outcomes.

Assisted reproductive technologies induce temporally specific placental defects and the preeclampsia risk marker sFLT1 in mouse.

Although widely used, assisted reproductive technologies (ARTs) are associated with adverse perinatal outcomes. To elucidate their underlying causes, we have conducted a longitudinal analysis of placental development and fetal growth using a mouse model to investigate the effects of individual ART procedures: hormone stimulation, in vitro fertilization (IVF), embryo culture and embryo transfer. We demonstrate that transfer of blastocysts naturally conceived without hormone stimulation and developed in vivo prior to transfer can impair early placentation and fetal growth, but this effect normalizes by term. In contrast, embryos cultured in vitro before transfer do not exhibit this compensation but rather display placental overgrowth, reduced fetal weight, reduced placental DNA methylation and increased levels of sFLT1, an anti-angiogenic protein implicated in causing the maternal symptoms of preeclampsia in humans. Increases in sFLT1 observed in this study suggest that IVF procedures could increase the risk for preeclampsia. Moreover, our results indicate that embryo culture is the major factor contributing to most placental abnormalities and should therefore be targeted for optimization.

Maternal weight affects placental DNA methylation of genes involved in metabolic pathways in the common marmoset monkey (Callithrix jacchus).

Accumulating evidence suggests that dysregulation of placental DNA methylation (DNAm) is a mechanism linking maternal weight during pregnancy to metabolic programming outcomes. The common marmoset, Callithrix jaccus, is a platyrrhine primate species that has provided much insight into studies of the primate placenta, maternal condition, and metabolic programming, yet the relationships between maternal weight and placental DNAm are unknown. Here, we report genome-wide DNAm from term marmoset placentas using reduced representation bisulfite sequencing. We identified 74 genes whose DNAm pattern is associated with maternal weight during gestation. These genes are predominantly involved in energy metabolism and homeostasis, including the regulation of glycolytic and lipid metabolic processes pathways.

Factors associated with maintenance of smoking cessation in adolescents after implementation of tobacco pricing policy in South Korea: Evidence from the 11th Youth Health Behavior Survey.

As a part of Korea's smoking cessation policy, the price of tobacco was increased in January 2015. Initially, the smoking rate among adolescents began to decrease. The current data, however, show that the adolescent smoking rate is on the rise. Alongside price policies, there is a need to further understand additional preventive measures that promote successful smoking cessation by identifying the factors that influence maintenance of smoking cessation in adolescents. This study aimed to identify the factors that influence smoking cessation in adolescents after attempting smoking cessation after increase in tobacco price. The study used large-scale, nationwide, secondary data obtained from the Korean Youth Risk Behavior Web-Based Survey. The sample included a total of 627 subjects who reported an attempt to quit smoking after the tobacco price increased. Descriptive statistics, t test, the χ2 test, and multiple logistic regression were used. The results showed that household economic status, school type, suicidal ideation, experience of exposure to secondhand smoke at home, and experience of witnessing teaching staff smoking were significant factors related to maintenance of smoking cessation among adolescents. To increase the success rate of smoking cessation, future intervention programs should include school environment structure and address emotional and psychological issues such as suicide.
