- Description: Comorbid depression and insomnia are ubiquitous mental complaints among women going through the perimenopausal stage of life and can result in major decline in quality of life. Antidepressive agents combined with/without hypnotics, and/or hormone therapy are currently the most common treatment for perimenopausal depression (PMD) and insomnia (PMI). Balancing the benefits of these pharmacotherapies against the risk of adverse events (AEs) is a difficult task for both clinicians and women. There has been a growing body of research regarding the utilization of acupuncture for treatment of PMD or PMI, whereas no studies of acupuncture for comorbid PMD and PMI have appeared. In this review, we summarize the clinical and preclinical evidence of acupuncture as a treatment for PMD or PMI, and then discuss the potential mechanisms involved and the role of acupuncture in helping women during this transition. Most clinical trials indicate that acupuncture ameliorates not only PMD/PMI but also climacteric symptoms with minimal AEs. It also regulates serum hormone levels. The reliability of trials is however limited due to methodological flaws in most studies. Rodent studies suggest that acupuncture prolongs total sleep time and reduces depression-like behavior in PMI and PMD models, respectively. These effects are possibly mediated through multiple mechanisms of action, including modulating sex hormones, neurotransmitters, hypothalamic-pituitary-adrenal axis/hypothalamic-pituitary-ovary axis, oxidative stress, signaling pathways, and other cellular events. In conclusion, acupuncture is a promising therapeutic strategy for comorbid depression and insomnia during perimenopause. Neuroendocrine modulation is likely to play a major role in mediating those effects. High-quality trials are required to further validate acupuncture’s effectiveness. © 2021 Zhao et al.

- Description: Background Regularly updated data on stroke and its pathological types, including data on their incidence, prevalence, mortality, disability, risk factors, and epidemiological trends, are important for evidence-based stroke care planning and resource allocation. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) aims to provide a standardised and comprehensive measurement of these metrics at global, regional, and national levels. Methods We applied GBD 2019 analytical tools to calculate stroke incidence, prevalence, mortality, disability-adjusted life-years (DALYs), and the population attributable fraction (PAF) of DALYs (with corresponding 95% uncertainty intervals [UIs]) associated with 19 risk factors, for 204 countries and territories from 1990 to 2019. These estimates were provided for ischaemic stroke, intracerebral haemorrhage, subarachnoid haemorrhage, and all strokes combined, and stratified by sex, age group, and World Bank country income level. Findings In 2019, there were 12·2 million (95% UI 11·0–13·6) incident cases of stroke, 101 million (93·2–111) prevalent cases of stroke, 143 million (133–153) DALYs due to stroke, and 6·55 million (6·00–7·02) deaths from stroke. Globally, stroke remained the second-leading cause of death (11·6% [10·8–12·2] of total deaths) and the third-leading cause of death and disability combined (5·7% [5·1–6·2] of total DALYs) in 2019. From 1990 to 2019, the absolute number of incident strokes increased by 70·0% (67·0–73·0), prevalent strokes increased by 85·0% (83·0–88·0), deaths from stroke increased by 43·0% (31·0–55·0), and DALYs due to stroke increased by 32·0% (22·0–42·0). During the same period, age-standardised rates of stroke incidence decreased by 17·0% (15·0–18·0), mortality decreased by 36·0% (31·0–42·0), prevalence decreased by 6·0% (5·0–7·0), and DALYs decreased by 36·0% (31·0–42·0). However, among people younger than 70 years, prevalence rates increased by 22·0% (21·0–24·0) and incidence rates increased by 15·0% (12·0–18·0). In 2019, the age-standardised stroke-related mortality rate was 3·6 (3·5–3·8) times higher in the World Bank low-income group than in the World Bank high-income group, and the age-standardised stroke-related DALY rate was 3·7 (3·5–3·9) times higher in the low-income group than the high-income group. Ischaemic stroke constituted 62·4% of all incident strokes in 2019 (7·63 million [6·57–8·96]), while intracerebral haemorrhage constituted 27·9% (3·41 million [2·97–3·91]) and subarachnoid haemorrhage constituted 9·7% (1·18 million [1·01–1·39]). In 2019, the five leading risk factors for stroke were high systolic blood pressure (contributing to 79·6 million [67·7–90·8] DALYs or 55·5% [48·2–62·0] of total stroke DALYs), high body-mass index (34·9 million [22·3–48·6] DALYs or 24·3% [15·7–33·2]), high fasting plasma glucose (28·9 million [19·8–41·5] DALYs or 20·2% [13·8–29·1]), ambient particulate matter pollution (28·7 million [23·4–33·4] DALYs or 20·1% [16·6–23·0]), and smoking (25·3 million [22·6–28·2] DALYs or 17·6% [16·4–19·0]). Interpretation The annual number of strokes and deaths due to stroke increased substantially from 1990 to 2019, despite substantial reductions in age-standardised rates, particularly among people older than 70 years. The highest age-standardised stroke-related mortality and DALY rates were in the World Bank low-income group. The fastest-growing risk factor for stroke between 1990 and 2019 was high body-mass index. Without urgent implementation of effective primary prevention strategies, the stroke burden will probably continue to grow across the world, particularly in low-income countries. © 2021 The Author(s).

- Description: Psychiatric readmissions contribute to a significant cost and healthcare burden to physicians, hospitals, and the healthcare system as an entity. Furthermore, as part of the Affordable Care Act, the Centers for Medicare and Medicaid Services (CMS) began to reduce financial coverage to hospitals with overwhelming rehospitalization rates. The purpose of this study was to do a systematic analysis on inpatient psychiatric readmission data and identify co-morbidities and risk factors that lead to high readmission rates. The data collection includes 163 patients with a total of 348 readmissions over the span of 90 days at one inner-city hospital in the Chicagoland area. Study findings suggest that higher rates of readmission are linked to cocaine abuse in both male and female populations. Diagnosis of bipolar in females and schizoaffective disorder in male populations were the among the highest for readmission. Key social factors such as homelessness and low socioeconomic status were identified to contribute to a large proportion of psychiatric readmission burden. However, an overwhelming amount of information was missing due to unobtained labs and lack of current patient social history. By using this data as well as data from electronic medical records (EMRs) to further investigate and identify other features of at-risk patients, hospitals can potentially address these markers to lower readmission rates. Ultimately, a higher understanding of the patients' needs can be understood and can help develop standardized plans of care for prevalent psychiatric illnesses in these populations.

- Description: Background: Few studies have directly compared the effects of different exercise therapies on clinical depression in older adults. Thus, we conducted a systematic review and network meta-analysis of current evidence from randomised controlled trials (RCTs) to compare the effectiveness of three major exercise types (aerobic, resistance, and mind-body exercise) in clinically depressed older adults. Methods: We followed PRISMA-NMA guidelines and searched databases for eligible RCTs (inception – September 12th, 2019). RCTs were eligible if they included clinically depressed adults aged >65 years, implemented one or more exercise therapy arms using aerobic, resistance, or mind-body exercise, and assessed depressive symptoms at baseline and follow-up using a validated clinical questionnaire. Results: A network meta-analysis was performed on 15 eligible RCTs comprising 596 participants (321 treatment and 275 controls), including aerobic (n = 6), resistance (n = 5), and mind-body (n = 4) exercise trials. Compared with controls, mind-body exercise showed the largest improvement on depressive symptoms (g = −0.87 to −1.38), followed by aerobic exercise (g = −0.51 to −1.02), and resistance exercise (g = −0.41 to −0.92). Notably, there were no statistically significant differences between exercise types: aerobic versus resistance (g = −0.10, PrI = −2.23, 2.03), mind-body versus aerobic (g = −0.36, PrI = −2.69, 1.97), or mind-body versus resistance (g = −0.46, PrI = −2.75, 1.83). Conclusions: These findings should guide optimal exercise prescription for allied health professionals and stakeholders in clinical geriatrics. Notably, clinically depressed older adults may be encouraged to self-select their preferred exercise type in order to achieve therapeutic benefit on symptoms of depression. In coalition with high levels of compliance, these data provide encouraging evidence for the antidepressant effect of either aerobic, resistance, or mind-body exercise as effective treatment adjucts for older adults presenting with clinical depression. © 2019

- Description: Vδ2+ T cells play a critical role in immunity to micro-organisms and cancer but exhibit substantial heterogeneity in humans. Here, we demonstrate that CD26 and CD94 define transcriptionally, phenotypically, and functionally distinct Vδ2+ T cell subsets. Despite distinct antigen specificities, CD26hiCD94lo Vδ2+ cells exhibit substantial similarities to CD26hi mucosal-associated invariant T (MAIT) cells, although CD26− Vδ2+ cells exhibit cytotoxic, effector-like profiles. At birth, the Vδ2+Vγ9+ population is dominated by CD26hiCD94lo cells; during adolescence and adulthood, Vδ2+ cells acquire CD94/NKG2A expression and the relative frequency of the CD26hiCD94lo subset declines. Critically, exposure of the CD26hiCD94lo subset to phosphoantigen in the context of interleukin-23 (IL-23) and CD26 engagement drives the acquisition of a cytotoxic program and concurrent loss of the MAIT cell-like phenotype. The ability to modulate the cytotoxic potential of CD26hiCD94lo Vδ2+ cells, combined with their adenosine-binding capacity, may make them ideal targets for immunotherapeutic expansion and adoptive transfer. Wragg et al. identify a population of human gd T cells with striking similarities to MAIT cells. These cells dominate the cord blood Vd2 population and upregulate an effector-like program upon antigen and IL-23 stimulation, providing a potential mechanism by which cytotoxic Vd2 cells may accumulate during adolescence and adulthood. © 2020

Here, we report that repeated sub-concussion with a light weight drop (25 g) in wild-type PVG rats for 2 weeks does not induce detectable neuromotor dysfunction assessed by beamwalk and rotarod tests. However, after 12 weeks of repeated sub-concussion, the rats exhibited moderate neuromotor dysfunction. This is the first study to demonstrate development of neuromotor dysfunction following multiple long-term sub-concussive impacts in rats. The outcomes may offer significant opportunity for future studies to understand the mechanisms of sub-concussion-induced neuropsychological changes. © Copyright © 2020 Lavender, Rawlings, Warnock, McGonigle, Hiles-Murison, Nesbit, Lam, Hackett, Fitzgerald and Takechi.

- Description: Emerging evidence suggests that disordered eating, particularly binge-eating symptomatology, is overrepresented within Polycystic Ovary Syndrome (PCOS) populations. This comorbidity presents a clinical dilemma as current treatment approaches for PCOS emphasize the importance of weight management, diet, exercise, and the potential for harm of such treatment approaches in PCOS patients with comorbid disordered eating. However, limited research has assessed the occurrence of binge eating and disordered eating in PCOS patients. Consequently, little is known about the prevalence of binge eating in PCOS, and the possible etiological processes to explain this comorbidity remain poorly understood. Given the paucity of research on this topic, the aims of this narrative review are fourfold: 1) to outline the main symptoms of PCOS and binge eating; 2) to provide an overview of the prevalence of binge eating in PCOS; 3) to outline possible etiological factors for the comorbidity between PCOS and binge eating; and 4) to provide an overview of management strategies of binge eating in PCOS.

This comorbidity presents a clinical dilemma as current treatment approaches for PCOS emphasize the importance of weight management, diet, exercise, and the potential for harm of such treatment approaches in PCOS patients with comorbid disordered eating. However, limited research has assessed the occurrence of binge eating and disordered eating in PCOS patients. Consequently, little is known about the prevalence of binge eating in PCOS, and the possible etiological processes to explain this comorbidity remain poorly understood. Given the paucity of research on this topic, the aims of this narrative review are fourfold: 1) to outline the main symptoms of PCOS and binge eating; 2) to provide an overview of the prevalence of binge eating in PCOS; 3) to outline possible etiological factors for the comorbidity between PCOS and binge eating; and 4) to provide an overview of management strategies of binge eating in PCOS.

- Description: Background: There are age-related differences in the manifestation of generalized anxiety disorder (GAD) symptoms and their associated impact on psychosocial and functional status. However, it remains unclear whether specific symptoms (or symptom patterns) are of comparable clinical significance across different functional domains. Methods: A sample of 865 self-reported worriers (aged 60 years and older) who endorsed GAD screening questions in the Alcohol Use Disorder and Associated Disabilities Interview Schedule, Diagnostic and Statistical Manual of Mental Disorders, fourth edition, were derived from Wave 1 of the National Epidemiological Survey of Alcohol and Related Conditions. Results: Being easily fatigued was significantly associated with occupational disability and a functional disability variable (restricting usual activity in any way). Irritability was significantly associated with social friction (arguments with friends, family, or colleagues) and a functional disability variable (found was unable to do something wanted to do), and poor self-perceived health was also associated with the same functional disability variable. Excessive worry, despite being among the least reported symptoms, was significantly associated with distress. Conclusions: These findings suggest that individual GAD symptoms are differentially associated with aspects of clinical significance relevant to daily life, such as social, occupational, and functional ability. The differential impact of individual symptoms on functional status may be diluted when using symptom sum scores. A nuanced approach to assessing the clinical significance of individual GAD symptoms in older adults may be fruitful for efforts aimed at early detection and treatment. © 2015 SAGE Publications.

- Description: Subarachnoid hemorrhage secondary to rupture of an intracranial aneurysm is a highly lethal medical condition. Current management strategies for unruptured intracranial aneurysms involve radiological surveillance and neurosurgical or endovascular interventions. There is no pharmacological treatment available to decrease the risk of aneurysm rupture and subsequent subarachnoid hemorrhage. There is growing interest in the pathogenesis of intracranial aneurysm focused on the development of drug therapies to decrease the incidence of aneurysm rupture. The study of rodent models of intracranial aneurysms has the potential to improve our understanding of intracranial aneurysm development and progression. This review summarizes current mouse models of intact and ruptured intracranial aneurysms and discusses the relevance of these models to human intracranial aneurysms. The article also reviews the importance of these models in investigating the molecular mechanisms involved in the disease. Finally, potential pharmaceutical targets for intracranial aneurysm suggested by previous studies are discussed. Examples of potential drug targets include matrix metalloproteinases, stromal cell-derived factor-1, tumor necrosis factor-α, the renin-angiotensin system and the β-estrogen receptor. An agreed clear, precise and reproducible definition of what constitutes an aneurysm in the models would assist in their use to better understand the pathology of intracranial aneurysm and applying findings to patients

- Description: Background The study examined the measurement equivalence for teacher ratings across Malaysian Malay, Chinese and Indian children. Methods Malaysian teachers completed ratings of the ODD symptoms for 574 Malay, 247 Chinese and 98 Indian children. Results The results supported the equivalences for the configural, metric, and error variances models, and the equivalences for ODD latent variances and mean scores. Discussion Together, these findings suggest good support for measurement and structural equivalences of the ODD symptoms across these ethnic groups. The theoretical and clinical implications of the findings for cross-cultural equivalence of the ODD symptoms are discussed.
