Life-course trajectories of body mass index from adolescence to old age: Racial and educational disparities.

No research exists on how body mass index (BMI) changes with age over the full life span and social disparities therein. This study aims to fill the gap using an innovative life-course research design and analytic methods to model BMI trajectories from early adolescence to old age across 20th-century birth cohorts and test sociodemographic variation in such trajectories. We conducted the pooled integrative data analysis (IDA) to combine data from four national population-based NIH longitudinal cohort studies that collectively cover multiple stages of the life course (Add Health, MIDUS, ACL, and HRS) and estimate mixed-effects models of age trajectories of BMI for men and women. We examined associations of BMI trajectories with birth cohort, race/ethnicity, parental education, and adult educational attainment. We found higher mean levels of and larger increases in BMI with age across more recent birth cohorts as compared with earlier-born cohorts. Black and Hispanic excesses in BMI compared with Whites were present early in life and persisted at all ages, and, in the case of Black-White disparities, were of larger magnitude for more recent cohorts. Higher parental and adulthood educational attainment were associated with lower levels of BMI at all ages. Women with college-educated parents also experienced less cohort increase in mean BMI. Both race and education disparities in BMI trajectories were larger for women compared with men.

Picturing the dance: intersections of gender, sexuality, and age in older women queer square dancers.

A dearth of research has focused on the diverse experiences of aging sexual minority populations and, in particular, older sexual minority women. Studies that have disaggregated the population of lesbian, gay, bisexual, transgender, questioning, queer, intersex and two-spirit (LGBTQIS+) older adults reveal that due to minority stress and a lifetime of disadvantage. Lesbians experience higher rates of chronic health conditions and mental health problems (including loneliness) than heterosexual women and greater financial inequalities compared to gay men or heterosexual women. Despite this, limited inquiry has explored the everyday lives of older queer women and fewer still draws upon women's commentary on their own lived experiences or centers older women as authoritative agents and experts on their own lives. In response to this knowledge deficit, this research traverses the aging experiences of female-identified members of a gay square dance (GSD) club in Toronto, Canada. We apply queer theory to explicate the unique ways in which a GSD club queers the aging process for 14 older women dancers. Findings of the inquiry highlight the ways in which these dancers confront and reject heteronormativity, while illuminating pathways to successful aging for older sexual diverse women. The older women dancers in this study perform gender in ways that challenged heteronormativity and gender binaries, enhanced belongingness and acceptance, embodied joy, and fostered wellness. These concepts have been identified as critical factors in successful aging and highlight what queering aging might look like for this resilient population who have overcome a lifetime of disadvantage.

Enhancing gerontological social work education: curriculum insights from offering a clinical gerontology certificate.

With the increasing aging population there is a need for more gerontological social work practitioners; however, such training for social workers in Canada is limited. To help address this gap, one faculty of social work developed a graduate level clinical social work practice certificate with a specialization in gerontology. In this paper we explore students' and instructors' perspectives about the curriculum, delivery, and impact of this certificate, and provide recommendations for improvement, particularly with respect to the clinical nature of the courses. Eight students and four instructors participated in the study. Strengths and opportunities for enhancement were identified for curriculum and delivery. Study findings also indicated that further curriculum development should focus on enhancing clinical skill development and providing more practice experience. Implications arising from these findings included developing clinical skills through experiential learning, interprofessional education, and service learning.

Disclosure and Reporting of Abuse Against Older Adults: Perspectives of Older Adults with Abuse Histories and Service Providers in Alberta, Canada.

This exploratory qualitative study seeks to understand the barriers and facilitators of disclosure and reporting of abuse against older adults by conducting interviews with older adults with lived experience of abuse and service providers working directly with this population in Alberta, Canada. Thematic analysis revealed three key themes: (1) Barriers to disclosure and reporting of abuse; (2) Facilitators to disclosure and reporting; and (3) Key tensions between service providers' and older adults' perceptions of the disclosure and reporting process. Based on these findings, we offer recommendations to increase awareness, promote disclosure, and improve services for older adults experiencing abuse.

Well-being at midlife: Correlates of mental health in ambulatory menopausal women with multiple sclerosis.

BACKGROUND: A majority of women with multiple sclerosis (MS) are diagnosed prior to menopause, yet their experiences during this transition are not well characterized. OBJECTIVES: To explore associations between mental health, sleep, and other quality of life metrics, and vasomotor symptoms (VMSs) in ambulatory, menopausal women with MS. METHODS: A secondary analysis was performed of baseline data from two trials enrolling ambulatory peri/postmenopausal women with MS: NCT02710214 (N = 24, bothersome VMS) and NCT04002934 (ongoing, N = 35, myelin repair). Measures analyzed were 36-Item Short-Form Survey (SF-36) (primary scale: general mental health), subjective sleep quality (Pittsburg Sleep Quality Index), VMS (daily diary, interference), mood (Center for Epidemiologist Studies-Depression Scale (CES-D)), walking impairment (timed 25-foot walk (T25FW)), and global disability (Expanded Disability Status Scale (EDSS)). RESULTS: Participants' characteristics (N = 59) were: mean age 51.8 years (SD = 3.4), mean disease duration 11.3 years (SD = 7.6), median EDSS 3.0 (IQR = 2.0-4.0). Mental health was associated with better sleep quality (rho = -0.41, p = 0.019) and better mood (rho = -0.75, p < 0.001), but not with EDSS or T25FW (rho < 0.20, p > 0.10). Worse sleep quality also correlated with more frequent VMS (rho = 0.41, p = 0.02) and VMS interference (rho = 0.59, p < 0.001). CONCLUSIONS: Findings suggest that optimizing sleep quality, mood, and hot flash quantity/interference could substantially improve mental health in menopausal women with MS-and highlight an important care gap in this population.

Molecular testing for endometrial cancer: An SGO clinical practice statement.

The Cancer Genome Atlas publication first described the genomic landscape of endometrial cancer and characterized these cancers into four molecular subtypes with different prognoses. The Proactive Molecular Classifier for Endometrial Cancer was developed to more easily and inexpensively classify endometrial cancers into four similar molecular subtypes which are termed POLE, mismatch repair deficient, p53 abnormal and no specific molecular profile. Beyond these four subtypes, other molecular biomarkers may influence clinical behavior and response to targeted therapies and include beta-catenin, Her2 amplification, PI3K/mTOR/AKT alterations, L1CAM, hormone receptor expression, tumor mutational burden, and ARID1A. There are numerous clinical trials exploring treatment escalation and de-escalation within the four molecular subtypes as well as matching targeted therapies to specific mutational or biomarker profiles. All endometrial cancers should undergo basic molecular classification that includes assessment of mismatch repair status. POLE and p53 status are prognostic and may become actionable in the future. Clinicians who treat patients with endometrial cancer should understand the role of molecular classification in guiding treatment. The goal of this practice statement is to guide appropriate testing, interpretation, and application of molecular information in endometrial cancer.

Patterns of care and outcomes of risk reducing surgery in women with pathogenic variants in non-BRCA and Lynch syndrome ovarian cancer susceptibility genes.

OBJECTIVES: Guidelines recommend risk-reducing bilateral salpingo-oophorectomy (RRSO) for women with pathogenic variants of non-BRCA and Lynch syndrome-associated ovarian cancer susceptibility genes. Optimal timing and findings at the time of RRSO for these women remains unclear. We sought to characterize practice patterns and frequency of occult gynecologic cancers for these women at our two institutions. METHODS: Women with germline ovarian cancer susceptibility gene pathogenic variants who underwent RRSO between 1/2000-9/2019 were reviewed in an IRB-approved study. All patients were asymptomatic with no suspicion for malignancy at time of RRSO. Clinico-pathologic characteristics were extracted from the medical records. RESULTS: 26 Non-BRCA (9 BRIP1, 9 RAD51C, and 8 RAD51D) and 75 Lynch (36 MLH1, 18 MSH2, 21 MSH6) pathogenic variants carriers were identified. Median age at time of RRSO was 47. There were no occurrences of occult ovarian or fallopian tube cancer in either group. Two patients (3%) in the Lynch group had occult endometrial cancer. Median follow up was 18 and 35 months for non-BRCA and Lynch patients, respectively. No patient developed primary peritoneal cancer upon follow up. Post-surgical complications occurred in 9/101 (9%) of patients. Hormone replacement therapy (HRT) was rarely used despite reported post-menopausal symptoms in 6/25 (23%) and 7/75 (37%) patients, respectively. CONCLUSIONS: No occult ovarian or tubal cancers were observed in either group. No recurrent or primary gynecologic-related cancers occurred upon follow-up. Despite frequent menopausal symptoms, HRT use was rare. Both groups experienced surgical complications when hysterectomy and/or concurrent colon surgery was performed suggesting concurrent surgeries should only be performed when indicated.

Alzheimer's disease phenotypes show different sleep architecture.

INTRODUCTION: Sleep-wake disturbances are a prominent feature of Alzheimer's disease (AD). Atypical (non-amnestic) AD syndromes have different patterns of cortical vulnerability to AD. We hypothesized that atypical AD also shows differential vulnerability in subcortical nuclei that will manifest as different patterns of sleep dysfunction. METHODS: Overnight electroencephalography monitoring was performed on 48 subjects, including 15 amnestic, 19 atypical AD, and 14 controls. AD was defined based on neuropathological or biomarker confirmation. We compared sleep architecture by visual scoring and spectral power analysis in each group. RESULTS: Overall, AD cases showed increased sleep fragmentation and N1 sleep compared to controls. Compared to atypical AD groups, typical AD showed worse N3 sleep dysfunction and relatively preserved rapid eye movement (REM) sleep. DISCUSSION: Results suggest differing effects of amnestic and atypical AD variants on slow wave versus REM sleep, respectively, corroborating the hypothesis of differential selective vulnerability patterns of the subcortical nuclei within variants. Optimal symptomatic treatment for sleep dysfunction in clinical phenotypes may differ. HIGHLIGHTS: Alzheimer's disease (AD) variants show distinct patterns of sleep impairment. Amnestic/typical AD has worse N3 slow wave sleep (SWS) impairment compared to atypical AD. Atypical AD shows more rapid eye movement deficits than typical AD. Selective vulnerability patterns in subcortical areas may underlie sleep differences. Relatively preserved SWS may explain better memory scores in atypical versus typical AD.

The Lived Experiences of Spousal Bereavement and Adjustment Among Older Chinese Immigrants in Calgary.

Spousal bereavement poses considerable challenges to adults in late life. Some populations, such as older immigrants, may experience heightened negative outcomes as a consequence of spousal bereavement, due to migratory stress and social isolation. Spousal bereavement is culturally embedded as it is related to cultural beliefs and attitudes concerning death and family relationships. However, studies on spousal bereavement or widowhood among older immigrants are extremely limited. This study aims to fill the gap by exploring, via a phenomenological approach, the lived experiences of widowed older Chinese immigrants in Calgary and responding to the question: What are the lived experiences of widowed Chinese older immigrants in coping with their spousal bereavement? With the data drawn from 12 in-depth qualitative interviews, findings were categorized into individual, family, community and societal levels. Study participants experienced long-lasting grief that was private and impacted by their culture and immigration status. Although family and ethno-cultural communities provided various types of supports during participants' widowhood, they did not directly assist them in coping with spousal loss. Most participants did not access social services for bereavement support, more often relying on cultural rituals and faith practices. Findings suggest the need for culturally appropriate bereavement supports and family/community involvement for older immigrant adults who have experienced spousal loss.

Delivering Services to Older Persons Experiencing Homelessness: Providers' Perspectives of What Does and Does Not Work.

Older people with experiences of homelessness (OPEH) tend to experience more complex health, social, and psychological issues than people experiencing homelessness at younger ages. Simultaneously, many housing resources (e.g., shelters, temporary housing) are often ill equipped to meet the needs of OPEH. As such, OPEH are often unable to age in the right place (AIRP) - that is, in a place that supports unique needs and vulnerabilities. However, several promising practices exist that deliver housing and services tailored to OPEH. To investigate the aspects of housing and shelter that both promote and impede AIRP for OPEH, this study examines the delivery of services in three such promising practices from the perspective of service providers. Findings from fifteen qualitative interviews revealed three overarching themes: 1) barriers to providing individualized support (e.g., staff turnover); 2) shifting contexts and structures (e.g., housing market changes); and 3) mechanisms of success (e.g., facilitating smooth transitions into permanent housing). These findings provide evidence to support the refinement of service delivery to promote AIRP for OPEH. In doing so, these insights can help to elevate promising practices to the level of best practice.

Breast cancer surveillance following ovarian cancer in BRCA mutation carriers.

OBJECTIVES: BRCA 1 or 2 mutation carriers have increased risk of developing breast cancer (BC) and serous epithelial ovarian cancer (EOC). The incidence of BC over time after EOC is unknown. Optimal BC surveillance for BRCA mutation carriers following EOC has not been defined. METHODS: A multi-institutional retrospective chart review was performed. Patients with BRCA -associated EOC diagnosed between 1996 and 2016 were followed for an average of 80 months. Women with previous bilateral mastectomy were excluded; women with prior BC and an intact breast were included. Descriptive statistics, Chi Square, and univariate survival analysis were performed. RESULTS: 184 patients with BRCA -associated EOC were identified. Eighteen (10%) were diagnosed with BC a median of 48 months following EOC. Two (1%) with prior BC developed contralateral BC and 16 (9%) developed primary BC. The majority of BC (55%) was diagnosed 3 years following EOC. The 3-, 5- and 10-year incidence of BC was 5.6%, 9.5% and 33.3%. Annual mammography was performed in 43% and MRI in 34%. Twenty-eight (15%) women underwent risk-reducing mastectomy (RRM). There was no statistically significant difference in BC screening between women with, and without, a prior BC. BC was most commonly detected on mammogram. Three (17%) women had occult BC at the time of RRM. Nine (50%) had DCIS, and 8 (44%) had stage I/II BC. Median 5- and 10-year survival was 68% and 43% and was comparable between groups. CONCLUSIONS: Ten percent of women developed BC after EOC. The incidence of BC following EOC in BRCA carriers increases over time, and surveillance is recommended given their enhanced survival of EOC. Timely genetic testing for women with EOC is imperative to better triage BC screening resources and treatment.

The severity of neuropsychiatric symptoms is higher in early-onset than late-onset Alzheimer's disease.

BACKGROUND AND PURPOSE: The faster rates of cognitive decline and predominance of atypical forms in early-onset Alzheimer's disease (EOAD) suggest that neuropsychiatric symptoms could be different in EOAD compared to late-onset AD (LOAD); however, prior studies based on non-biomarker-diagnosed cohorts show discordant results. Our goal was to determine the profile of neuropsychiatric symptoms in EOAD and LOAD, in a cohort with biomarker/postmortem-confirmed diagnoses. Additionally, the contribution of co-pathologies was explored. METHODS: In all, 219 participants (135 EOAD, 84 LOAD) meeting National Institute on Aging and Alzheimer's Association criteria for AD (115 amyloid positron emission tomography/cerebrospinal fluid biomarkers, 104 postmortem diagnosis) at the University of California San Francisco were evaluated. The Neuropsychiatric Inventory-Questionnaire (NPI-Q) was assessed at baseline and during follow-up. The NPI-Q mean comparisons and regression models adjusted by cognitive (Mini-Mental State Examination) and functional status (Clinical Dementia Rating Sum of Boxes) were performed to determine the effect of EOAD/LOAD and amnestic/non-amnestic diagnosis on NPI-Q. Regression models assessing the effect of co-pathologies on NPI-Q were performed. RESULTS: At baseline, the NPI-Q scores were higher in EOAD compared to LOAD (p < 0.05). Longitudinally, regression models showed a significant effect of diagnosis, where EOAD had higher NPI-Q total, anxiety, motor disturbances and night-time behavior scores (p < 0.05). No differences between amnestics/non-amnestics were found. Argyrophilic grain disease co-pathology predicted a higher severity of NPI-Q scores in LOAD. CONCLUSIONS: Anxiety, night-time behaviors and motor disturbances are more severe in EOAD than LOAD across the disease course. The differential patterns of neuropsychiatric symptoms observed between EOAD/LOAD could suggest a pattern of selective vulnerability extending to the brain's subcortical structures. Further, co-pathologies such as argyrophilic grain disease in LOAD may also play a role in increasing neuropsychiatric symptoms.

Residential bacteria and fungi identified by high-throughput sequencing and childhood respiratory health.

The objective of this study was to examine and compare environmental microbiota from dust and children's respiratory health outcomes at ages seven and twelve. At age seven, in-home visits were conducted for children enrolled in the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS). Floor dust was collected and analyzed for bacterial (16 S rRNA gene) and fungal (internal transcribed spacer region) microbiota. Respiratory outcomes, including physician-diagnosed asthma, wheeze, rhinitis, and aeroallergen sensitivity were assessed by physical examination and caregiver-report at ages seven and twelve. The associations between dust microbiota and respiratory outcomes were evaluated using Permanova, DESeq, and weighted quantile sum (WQS) regression models. Four types of WQS regression models were run to identify mixtures of fungi or bacteria that were associated with the absence or presence of health outcomes. For alpha or beta diversity of fungi and bacteria, no significant associations were found with respiratory health outcomes. DESeq identified specific bacterial and fungal indicator taxa that were higher or lower with the presence of different health outcomes. Most individual indicator fungal species were lower with asthma and wheeze and higher with aeroallergen positivity and rhinitis, whereas bacterial data was less consistent. WQS regression models demonstrated that a combination of species might influence health outcomes. Several heavily weighted species had a strong influence on the models, and therefore, created a microbial community that was associated with the absence or presence of asthma, wheeze, rhinitis, and aeroallergen+. Weights for specific species within WQS regression models supported indicator taxa findings. Health outcomes might be more influenced by the composition of a complex mixture of bacterial and fungal species in the indoor environment than by the absence or presence of individual species. This study demonstrates that WQS is a useful tool in evaluating mixtures in relation to potential health effects.

Society of Gynecologic Oncology recommendations for fellowship education during the COVID-19 pandemic and beyond: Innovating programs to optimize trainee success.

In approximately ten months' time, the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has infected over 34 million people and caused over one million deaths worldwide. The impact of this virus on our health, relationships, and careers is difficult to overstate. As the economic realities for academic medical centers come into focus, we must recommit to our core missions of patient care, education, and research. Fellowship education programs in gynecologic oncology have quickly adapted to the "new normal" of social distancing using video conferencing platforms to continue clinical and didactic teaching. United in a time of crisis, we have embraced systemic change by developing and delivering collaborative educational content, overcoming the limitations imposed by institutional silos. Additional innovations are needed in order to overcome the losses in program surgical volume and research opportunities. With the end of the viral pandemic nowhere in sight, program directors can rethink how education is best delivered and potentially overhaul aspects of fellowship curriculum and content. Similarly, restrictions on travel and the need for social distancing has transformed the 2020 fellowship interview season from an in-person to a virtual experience. During this time of unprecedented and rapid change, program directors should be particularly mindful of the needs and health of their trainees and consider tailoring their educational experiences accordingly.

The mycobiomes and bacteriomes of sputum, saliva, and home dust.

Respiratory microbiome is an understudied area of research compared to other microbiomes of the human body. The respiratory tract is exposed to an array of environmental pollutants, including microbes. Yet, we know very little about the relationship between environmental and respiratory microbiome. The primary aim of our study was to compare the mycobiomes and bacteriomes between three sample types from the same participants, including home dust, saliva, and sputum. Samples were collected from 40 adolescents in a longitudinal cohort. We analyzed the samples using 16s bacterial rDNA and ITS fungal rDNA gene sequencing, as well as quantitative PCR with universal fungal and bacterial primers. Results showed that home dust had the greatest alpha diversity between the three sample types for both bacteria and fungi. Dust had the highest total fungal load and the lowest total bacterial load. Sputum had greater bacterial diversity than saliva, but saliva had greater fungal diversity than sputum. The distribution of major bacterial phyla differed between all sample types. However, the distribution of major fungal classes differed only between sputum and saliva. Future research should examine the biological significance of the taxa found in each sample type based on microbial ecology and associations with health effects.

Service providers' use of harm reduction approaches in working with older adults experiencing abuse: a qualitative study.

BACKGROUND: Although abuse experienced by older adults is common and expected to increase, disclosure, reporting and interventions to prevent or mitigate abuse remain sub-optimal. Incorporating principles of harm reduction into service provision has been advocated as a strategy that may improve outcomes for this population. This paper explores whether and how these principles of harm reduction were employed by professionals who provide services to older adults experiencing abuse. METHODS: Thematic analysis of qualitative interviews with 23 professionals providing services to older adults experiencing abuse across three Western provinces of Canada was conducted. Key principles of harm reduction (humanism, incrementalism, individualism, pragmatism, autonomy, and accountability without termination) were used as a framework for organizing the themes. RESULTS: Our analysis illustrated a clear congruence between each of the six harm reduction principles and the approaches reflected in the narratives of professionals who provided services to this population, although these were not explicitly articulated as harm reduction by participants. Each of the harm reduction principles was evident in service providers' description of their professional practice with abused older adults, although some principles were emphasized differentially at different phases of the disclosure and intervention process. Enactment of a humanistic approach formed the basis of the therapeutic client-provider relationships with abused older adults, with incremental, individual, and pragmatic principles also apparent in the discourse of participants. While respect for the older adult's autonomy figured prominently in the data, concerns about the welfare of the older adults with questionable capacity were expressed when they did not engage with services or chose to return to a high-risk environment. Accountability without termination of the client-provider relationship was reflected in continuation of support regardless of the decisions made by the older adult experiencing abuse. CONCLUSIONS: Harm reduction approaches are evident in service providers' accounts of working with older adults experiencing abuse. While further refinement of the operational definitions of harm reduction principles specific to their application with older adults is still required, this harm reduction framework aligns well with both the ethical imperatives and the practical realities of supporting older adults experiencing abuse.

Care Coordination in Emergency Departments for Children and Adolescents With Behavioral Health Conditions: Assessing the Degree of Regular Follow-up After Psychiatric Emergency Department Visits.

BACKGROUND: Increasing numbers of children are receiving care for behavioral health conditions in emergency departments (EDs). However, studies of mental health-related care coordination between EDs and primary and/or specialty care settings are limited. Such coordination is important because ED care alone may be insufficient for patients' behavioral health needs. METHODS: We analyzed claims during the year 2014 from Truven Health Analytics MarketScan Medicaid and Commercial databases for outpatient services and prescription drugs for youth 2 to 18 years old with continuous enrollment. We applied a standard care coordination measure to insurance claims data in order to examine whether youth received a primary care or specialty follow-up visit within 7 days following an ED visit with a psychiatric diagnosis. We calculated descriptive statistics to evaluate differences in care coordination by enrollees' demographic, insurance, and health-related characteristics. In addition, we constructed a multivariate logistic regression model to detect the factors associated with the receipt of care coordination. RESULTS: The total percentages of children who received care coordination were 45.8% (Medicaid) and 46.6% (private insurance). Regardless of insurance coverage type, children aged 10 to 14 years had increased odds of care coordination compared with youth aged 15 to 18 years. Children aged 2 to 5 years and males had decreased odds of care coordination. CONCLUSIONS: It is of concern that fewer than half of patients received care coordination following an ED visit. Factors such as behavioral health workforce shortages, wait times for an appointment with a provider, and lack of reimbursement for care coordination may help explain these results.

Deepen into sleep and wake patterns across Alzheimer's disease phenotypes.

Although, the clinical variants of Alzheimer's disease (AD) show distinct patterns of cognitive and behavioral decline, disease progression, and neuropathological features, it is unclear if this clinical heterogeneity extends to sleep-wake patterns. Sleep and wake disturbances are frequent in typical AD, often preceding memory loss and negatively impacting the quality of life of patients and caregivers alike. Still, sleep and wake disorders are often misdiagnosed and undertreated in typical AD. Better characterization of sleep-wake features in AD clinical variants is an unmet gap of high importance because these differing patterns may require tailored treatment strategies. Moreover, as wake-promoting neurons are located in subcortical nuclei and degenerate early in typical AD, contrasting the profiles of sleep-wake patterns in typical and atypical AD aids diagnosis and brings a unique opportunity to uncover the mechanisms underlying AD clinical variants at the subcortical level and mechanisms for selective neuronal vulnerability.

The role of co-neurotransmitters in sleep and wake regulation.

Sleep and wakefulness control in the mammalian brain requires the coordination of various discrete interconnected neurons. According to the most conventional sleep model, wake-promoting neurons (WPNs) and sleep-promoting neurons (SPNs) compete for network dominance, creating a systematic "switch" that results in either the sleep or awake state. WPNs and SPNs are ubiquitous in the brainstem and diencephalon, areas that together contain <1% of the neurons in the human brain. Interestingly, many of these WPNs and SPNs co-express and co-release various types of the neurotransmitters that often have opposing modulatory effects on the network. Co-transmission is often beneficial to structures with limited numbers of neurons because it provides increasing computational capability and flexibility. Moreover, co-transmission allows subcortical structures to bi-directionally control postsynaptic neurons, thus helping to orchestrate several complex physiological functions such as sleep. Here, we present an in-depth review of co-transmission in hypothalamic WPNs and SPNs and discuss its functional significance in the sleep-wake network.

Latest clinical evidence of maintenance therapy in ovarian cancer.

PURPOSE OF REVIEW: To summarize the data supporting the use of maintenance therapy in ovarian cancer treatment. RECENT FINDINGS: Since December 2016, the United States Food and Drug Administration has approved four drugs for six different ovarian cancer maintenance indications based on the results of clinical trials demonstrating efficacy and tolerability. These include antiangiogenesis and poly (adenosine diphosphate-ribose) inhibitors (PARP inhibitors). Four drugs are approved for use in maintenance therapy for recurrent ovarian cancer, including bevacizumab (GOG-0213 and OCEANS), niraparib (NOVA), olaparib (Study 19 and SOLO2) and rucaparib (ARIEL3). Two drugs are approved for use in maintenance therapy in newly diagnosed ovarian cancer, including bevacizumab (GOG-0218) and olaparib (SOLO1). New data were reported at the European Society for Medical Oncology Congress in October 2019 that may lead to the approval of additional strategies in front-line maintenance, including the use of niraparib (PRIMA), veliparib (VELIA) and bevacizumab + olaparib (PAOLA). SUMMARY: The landscape of maintenance treatment options for ovarian cancer has been rapidly expanding and continues to evolve as new data emerge. Currently approved strategies include antiangiogenesis and PARP inhibitor treatments.
