Pregnancy as a window of opportunity for dementia prevention: a narrative review.

Dementia is a debilitating condition with a disproportionate impact on women. While sex differences in longevity contribute to the disparity, the role of the female sex as a biological variable in disease progression is not yet fully elucidated. Metabolic dysfunctions are drivers of dementia etiology, and cardiometabolic diseases are among the most influential modifiable risk factors. Pregnancy is a time of enhanced vulnerability for metabolic disorders. Many dementia risk factors, such as hypertension or blood glucose dysregulation, often emerge for the first time in pregnancy. While such cardiometabolic complications in pregnancy pose a risk to the health trajectory of a woman, increasing her odds of developing type 2 diabetes or chronic hypertension, it is not fully understood how this relates to her risk for dementia. Furthermore, structural and functional changes in the maternal brain have been reported during pregnancy suggesting it is a time of neuroplasticity for the mother. Therefore, pregnancy may be a window of opportunity to optimize metabolic health and support the maternal brain. Healthy dietary patterns are known to reduce the risk of cardiometabolic diseases and have been linked to dementia prevention, yet interventions targeting cognitive function in late life have largely been unsuccessful. Earlier interventions are needed to address the underlying metabolic dysfunctions and potentially reduce the risk of dementia, and pregnancy offers an ideal opportunity to intervene. This review discusses current evidence regarding maternal brain health and the potential window of opportunity in pregnancy to use diet to address neurological health disparities for women.

A high fiber diet intervention during pregnancy: The SPROUT (Single goal in PRegnancy to optimize OUTcomes) protocol paper.

BACKGROUND: Interventions to prevent excessive gestational weight gain (GWG) have had a limited impact on maternal and infant outcomes. Dietary fiber is a nutrient with benefits that counters many of the metabolic and inflammatory changes that occur during pregnancy. We will determine if a high dietary fiber (HFib) intervention provides benefit to maternal and infant outcomes. METHODS AND DESIGN: Pregnant women will be enrolled in an 18-week intervention and randomized in groups of 6-10 women/group into the intervention or control group. Weekly lessons will include information on high-dietary fiber foods and behavior change strategies. Women in the intervention group will be given daily snacks high in dietary fiber (10-12 g/day) to facilitate increasing dietary fiber intake. The primary aim will assess between-group differences for the change in maternal weight, dietary fiber intake, dietary quality, and body composition during pregnancy and up to two months post-partum. The secondary aim will assess between-group differences for the change in maternal weight, dietary fiber intake, and dietary quality from two months to one year post-partum and infant body composition from birth to one-year-old. DISCUSSION: Effective and simple intervention strategies to improve maternal and offspring outcomes are lacking. Changes during the perinatal period are related to the risk of disease development in the mother and offspring. However, it is unknown which changes can be successfully targeted to have a meaningful impact. We will test the effect of an intervention designed to counter many of the metabolic and inflammatory changes that occur during pregnancy. ETHICS AND DISSEMINATION: The University of Kansas Medical Center Institutional Review Board (IRB) approved the study protocol (STUDY00145397). The results of the trial will be disseminated at conferences and in peer reviewed publications. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT04868110.

Feasibility of a Weight Management Program Tailored for Overweight Men with Localized Prostate Cancer - A Pilot Study.

BACKGROUND: Overweight men with prostate cancer are more likely to suffer from recurrence and death following prostatectomy compared with healthy weight men. This study tested the feasibility of delivering a comprehensive program to foster weight loss before and weight maintenance after surgery in overweight men with localized prostate cancer. METHODS: Twenty overweight men scheduled for prostatectomy elected either the intervention (n = 15) or the nonintervention (n = 5). Anthropometrics, biomarkers, diet quality, nutrition literacy, quality of life, and long-term follow-up were assessed in both groups. RESULTS: The intervention led to 5.55 kg of weight loss including 3.88 kg of fat loss from baseline to surgery (mean = 8.3 weeks). The intervention significantly increased fiber, protein, fruit, nut, and vegetable intake; and decreased trans fats intake during weight loss. The intervention significantly reduced insulin, C-peptide, systolic blood pressure, leptin:adiponectin ratio, and visceral adiposity compared to the nonintervention. Post-surgically, weight loss was maintained. Changes in lipid profiles, nutrition literacy, and follow-up were not statistically significant in either group. CONCLUSION: Significant weight loss (≥5%) is feasible with a coaching intervention in overweight men preparing for prostatectomy and is associated with favorable cardiometabolic effects. This study is registered under NCT02252484 (www.clinicaltrials.gov).

Integrating Family Caregiver Support Into a Gynecologic Oncology Practice: An ASCO Quality Training Program Project.

PURPOSE: A needs assessment of family caregivers (CGs) in our gynecologic oncology clinic found that 50% of CGs report nine or more distressing unmet needs, but only 19% of patients had a documented CG. We conducted an ASCO Quality Training Program project with the following aims: (1) to identify and document primary CGs for 85% of patients within two clinic visits of a gynecologic cancer diagnosis, and (2) assess the needs of and provide interventions to 75% of identified family CGs. METHODS: Plan-Do-Study-Act (PDSA) methodology and tools endorsed by the ASCO Quality Training Program were used. An interprofessional team reviewed baseline data (ie, any mention of a family CG in the electronic health record visit note; CG distress survey), defined the problem and project aims, created process maps, and identified root causes of poor CG identification and documentation. Eight successive PDSA cycles were implemented between October 2018 and March 2019 to address identified root causes. RESULTS: For aim 1, CG identification increased from 19% at baseline to 57% postimplementation, whereas for aim 2, assessment improved from 28% at baseline to 60% postimplementation. Results fell somewhat short of initial goals, but they represent an important initial improvement in care. The core team has begun additional PDSA cycles to improve CG identification rates and extend the momentum of the project. CONCLUSION: This project demonstrated that a CG assessment protocol can be implemented in a large, academic, gynecologic oncology clinic. Additional efforts to integrate CG identification, assessment, and intervention more fully within the clinic and electronic health record are under way.

Glycemic impact of a diet and lifestyle intervention on diabetics and prediabetics during treatment for non-muscle invasive bladder cancer.

Introduction: Patients with Type II Diabetes Mellitus (DM2) have increased risk of recurrence and progression of non-muscle invasive bladder cancer (NMIBC). Glucose control through lifestyle intervention is an uninvestigated, attractive strategy to decrease risk of cancer recurrence. We test the feasibility of a diet and exercise program and its glycemic impact in patients with DM2 and NMIBC.Materials/methods: Five participants with NMIBC and pre-diabetes or DM2 were recruited for a pilot, prospective clinical trial. Each participant received dietary counseling for 16 sessions during clinical visits. The intervention included a carbohydrate-restricted (CR) diet (<130 grams per day), 30 min, walking 5×/wk, and 5000 steps daily. Diet compliance was measured with 24-hour diet recall. Exercise was monitored with accelerometer and self-report.Results: Five participants enrolled and two participants completed the 12-month intervention. Adherence was 60% to CR diet and 84% to exercise goals. Participants reduced carbohydrate consumption by 44%. Participants showed reductions in fasting blood glucose, HbA1c, glucosuria, fasting blood insulin, and body weight, and increased euglycemia on continuous glucose monitoring.Conclusions: Adherence to a CR diet and exercise goals is feasible in patients with NMIBC and DM2 and also leads improved glucose control. A phase-II trial on bladder cancer-specific outcomes is warranted.

Caring for Survivors of Gynecologic Cancer: Assessment and Management of Long-term and Late Effects.

OBJECTIVE: To define important aspects of survivorship care for the more than 1.2million survivors of gynecologic cancer currently living in the US. DATA SOURCES: Research articles, reviews, position statements and white papers, and evidence-based guidelines. CONCLUSION: Survivorship care includes a coordinated plan of care, ongoing surveillance, health promotion support, and management of long-term and late effects of treatment. IMPLICATIONS FOR NURSING PRACTICE: Nurses need to be aware of the current guidelines for post-treatment surveillance and health promotion recommendations for survivors of gynecologic cancers. Early identification of long-term and late effects of treatment followed by coordinated medical intervention and self-management education are essential to improve quality of life.

Defining Essential Elements of Caregiver Support in Gynecologic Cancers Using the Modified Delphi Method.

PURPOSE: Family caregivers are instrumental to patients with gynecologic cancer and can be deeply affected by the demands of caregiving. Our aims were as follows: (1) increase awareness of unmet needs of caregivers and (2) identify and prioritize the unmet needs of caregivers and essential support services to be provided in gynecologic cancer centers. METHODS: From July 2017 to June 2018, a 16-person steering committee and 40 stakeholders, including caregivers, patients, and clinicians, participated in a modified Delphi approach to generate, review, and prioritize a set of essential elements for caregiver support. Stakeholders prioritized caregiver needs and brainstormed, discussed, and prioritized essential support services to meet those needs, using three rounds of a consensus-building protocol. Basic descriptive statistics were performed to feed means and rankings back to stakeholders before each round. RESULTS: The top three caregiver needs were as follows: (1) to obtain information about their loved one's cancer, (2) how to provide support and comfort to their loved one, and (3) how to maintain their own emotional health and well-being. Fifteen essential elements of support for caregivers of patients with gynecologic cancer were identified and ranged from elements currently attainable (eg, information on managing symptoms, skilled-care training, a point person to help navigate the system) to more aspirational elements (eg, integrative services to promote caregiver well-being). CONCLUSION: To ensure comprehensive quality care, clinicians and health care providers should strive to provide caregivers with the identified essential elements of support. Health care settings should work to incorporate caregiver needs into cancer care delivery.

Caregiving Is a Marathon, Not a Road Race: Reenvisioning Caregiver Support Services in Gynecologic Oncology.

OBJECTIVES: As gynecologic cancer care shifts to the outpatient setting, caregivers are instrumental in helping patients navigate the demands of the disease and treatment. Through social media, we aimed to understand the needs of caregivers of patients with gynecologic cancers and support services necessary to meet these needs. METHODS: On January 10, 2018, a monthly Twitter discussion session was hosted by the GYNecologic Cancer Social Media community (handle @GYNCSM) using the hashtag #GYNCSM. Five topics regarding caregiver needs and support were discussed. Basic descriptive statistics, including means and frequencies of tweets, and a content analysis of the tweets were performed. RESULTS: Forty-six participants posted a total of 471 tweets, with 1.725 million impressions. Four main themes of caregiver needs emerged, including accepting help from others, a need to care for themselves as caregivers, increased access to information and resources, and a need for the health care team to communicate with caregivers. Themes relating to barriers to obtaining support services included practical barriers, a lack of awareness, negative emotions, and a need to do it all themselves. Participants suggested that caregiver support programs include convenient resources, caregiver peer support programs, support for the "work" of caregiving, and support to improve the emotional and physical health of the caregiver. CONCLUSIONS: Experts, patients, and caregivers effectively engaged in social media to identify a wide range of needs of caregivers of women with gynecologic cancers. Further research is needed to identify specific support services that could meet the priority needs of a broader network of caregivers.

Utilizing V-Y fasciocutaneous advancement flaps for vulvar reconstruction.

OBJECTIVES: We aimed to analyze the outcomes of patients who underwent vulvectomy with subsequent V-Y fasciocutaneous flap reconstruction. METHODS: All medical records of all patients who underwent vulvectomies with V-Y fasciocutaneous flap reconstruction from January 2007 to June 2016 were retrospectively reviewed. Patient clinical and surgical data, demographics, and outcomes were abstracted. RESULTS: Of the 27 patients, 42 flaps were transferred. A simple vulvectomy was performed in 8 (30%) patients, partial radical vulvectomy in 15 (56%), and radical vulvectomy in 4 (15%). The median area of defect was 30 cm2. Minor wound separations occurred in 9 patients (33%). Infectious complications occurred in 4 patients (15%); this included urinary tract infections in 2 (50%), postoperative fevers in 2 (50%), and sepsis in 1 (25%) patient with a UTI. There were no instances of flap necrosis, wound dehiscence, or wound infections. Black race was more likely to be associated with an infectious complication with 3 (75%) patients, compared to white race with 1 (4%) patient (p < .01). The presence of diabetes was more likely to be associated with an infectious complication in 2 (67%) patients, compared to 1 (4%) in non-diabetic patients (p < .01). No other significant association was found during analysis of demographics, medical comorbidities, vulvar pathology, or surgical factors affecting V-Y fasciocutaneous flap infectious complications or minor wound separations. CONCLUSIONS: The use of a V-Y fasciocutaneous advancement flap for vulvar reconstruction is safe and associated with mostly minor complications. Infectious complications were more frequently associated with diabetes, black race, and HIV.

Perioperative Immunonutrition Modulates Inflammatory Response after Radical Cystectomy: Results of a Pilot Randomized Controlled Clinical Trial.

PURPOSE: Poor preoperative nutritional status is associated with a higher complication rate after radical cystectomy in patients with bladder cancer. Given the short interval between diagnosis and radical cystectomy, we compared the effect of short-term specialized immunonutrition to that of a standard oral nutritional supplement on the acute inflammatory response and arginine status in patients treated with radical cystectomy. MATERIALS AND METHODS: In this prospective, randomized study in 29 men 14 received specialized immunonutrition and 15 received oral nutritional supplement. Each group drank 3 cartons per day for 5 days before and 5 days after radical cystectomy. The Th1-Th2 balance, plasma interleukin-6 and plasma amino acids were measured at baseline, intraoperatively and on postoperative days 2, 14 and 30. Body composition was measured by dual energy x-ray absorptiometry at baseline and on postoperative days 14 and 30. Differences in outcomes were assessed using the generalized linear mixed model. RESULTS: In the specialized immunonutrition group there was a 54.3% average increase in the Th1-Th2 balance according to the tumor necrosis factor-α-to-interleukin-13 ratio from baseline to intraoperative day, representing a shift toward a Th1 response. In the oral nutritional supplement group the Th1-Th2 balance decreased 4.8%. The change in the Th1-Th2 balance between the specialized immunonutrition and oral nutritional supplement groups significantly differed (p <0.027). Plasma interleukin-6 was 42.8% lower in the specialized immunonutrition group compared to the oral nutritional supplement group on postoperative day 2 (p = 0.020). In the specialized immunonutrition group plasma arginine was maintained from baseline to postoperative day 2 and yet the oral nutritional supplement group showed a 26.3% reduction from baseline to postoperative day 2 (p = 0.0003). The change in appendicular muscle loss between the groups was not statistically significant. CONCLUSIONS: Th1-to-Th2 ratios, peak interleukin-6 levels and plasma arginine suggest that consuming specialized immunonutrition counteracts the disrupted T-helper balance, lowers the inflammatory response and prevents arginine depletion due to radical cystectomy.

Microcystic, Elongated, and Fragmented Pattern Invasion in Ovarian Endometrioid Carcinoma: Immunohistochemical Profile and Prognostic Implications.

Microcystic, elongated, and fragmented (MELF) pattern invasion is a poor prognostic indicator in uterine endometrioid carcinoma, but its existence, biology, and prognostic value have not been described in ovarian endometrioid carcinoma. We evaluated cases of ovarian endometrioid carcinoma without synchronous uterine endometrioid carcinoma for MELF and other histologic features. To evaluate tumor biology, we assessed an immunohistochemical profile, including MLH1, PMS2, MSH2, MSH6, ß-catenin, e-cadherin, CK19, and cyclin D1. A retrospective chart review evaluated clinical and demographic features and survival. The Fisher exact test analyzed data. The Kaplan-Meier method assessed overall survival. Forty-two patients met inclusion criteria. MELF was found in 45%. Two MELF cases showed MSH2/MSH6 deficiency and 2 conventional cases showed PMS2 deficiency. Clear cell features were seen exclusively in MELF cases (P-value=0.044). No difference was identified in overall survival, cancer recurrence, serous features, concurrent endometriosis, lymphovascular space invasion, lymph node metastasis, bilaterality of disease, extranodal metastasis, or remainder of immunohistochemical profile. MELF occurs at similar rates in ovarian endometrioid carcinoma and uterine endometrioid carcinoma and can be helpful in defining ovarian endometrioid carcinoma as it proves definitive invasion. Recurrence and overall survival in ovarian endometrioid carcinoma are not affected by MELF. Clear cell features are identified exclusively in MELF cases. Different mismatch repair proteins are lost in MELF compared with conventional ovarian endometrioid carcinomas. Given its association with clear cell features and mismatch repair protein loss, presence of MELF may be useful in clinical decisions regarding surgical staging and Lynch syndrome screening.

Outpatient versus inpatient management for superimposed preeclampsia without severe features: a retrospective, multicenter study.

PURPOSE: To determine if women with preterm superimposed preeclampsia without severe features can be successfully and safely triaged to outpatient management. MATERIALS AND METHODS: This was a multicenter, retrospective, cohort study of singleton pregnancies with superimposed preeclampsia without severe features diagnosed before 37 weeks managed outpatient versus inpatient at Thomas Jefferson University (Philadelphia, PA) and at University of Naples (Naples, Italy) from January 2008 to July 2015. The attending physician made the decision to manage outpatient or inpatient at his or her discretion. The primary outcome was composite maternal morbidity defined as development of at least one of the following: severe features, HELLP syndrome, placental abruption, eclampsia, postpartum hemorrhage, intensive care unit admission, or maternal death. Logistic regression, presented as adjusted odds ratio (aOR) with the 95% of confidence interval (CI) was performed. RESULTS: A total of 365 women with superimposed preeclampsia without severe features before 37 weeks were analyzed. 198 (54.2%) were managed outpatient, and 167 (45.8%) were managed inpatient. Women managed as outpatients had a similar rate of maternal morbidity compared to those managed as inpatients (36.4% versus 41.3%, aOR 0.82, 95%CI 0.55-1.17). Fetuses from women in the outpatient group had a significantly lower risk of small for gestational age (17.7% versus 29.3%; aOR 0.53, 95%CI 0.30-0.84), and lower risk of admission to neonatal intensive care unit (40.4% versus 47.9%; aOR 0.72, 95%CI 0.39-0.95) compared to women managed as inpatients. CONCLUSIONS: Low risk women with superimposed preeclampsia without severe features can be triaged to outpatient management without increased maternal morbidity.

Incidental leiomyosarcoma found at the time of cesarean hysterectomy for morbidly adherent placenta.

BACKGROUND: Incidental leiomyosarcoma (LMS) is a rare diagnosis in pregnancy or in the puerperium. To our knowledge, this is the first case reported in the literature of incidental LMS after cesarean hysterectomy for morbidly adherent placenta. CASE: We present a case of a cesarean hysterectomy performed for a suspected morbidly adherent placenta in a patient with three prior cesarean deliveries, an anterior placenta previa and a fundal fibroid. Subsequent pathology identified a LMS on final specimen. The patient declined bilateral oophorectomy and removal of her remaining cervix. No chemotherapy or radiation was given for her presumed stage IB disease. CONCLUSION: An incidental finding of a LMS is infrequent; the risk of recurrence is > 50% even if the sarcoma is removed in its entirety.

Effects of Immunonutrition for Cystectomy on Immune Response and Infection Rates: A Pilot Randomized Controlled Clinical Trial.

UNLABELLED: After radical cystectomy (RC), patients are at risk for complications including infections. The expansion of myeloid-derived suppressor cells (MDSCs) after surgery may contribute to the lower resistance to infection. Immune response and postoperative complications were compared in men consuming either specialized immunonutrition (SIM; n=14) or an oral nutrition supplement (ONS; n=15) before and after RC. MDSC count (Lin- CD11b+ CD33+) was significantly different between the groups over time (p=0.005) and significantly lower in SIM 2 d after RC (p<0.001). MDSC count expansion from surgery to 2 d after RC showed a weak association with an increase in infection rate 90 d after surgery (p=0.061). Neutrophil:lymphocyte ratio was significantly lower in SIM compared with ONS 3h after the first incision (p=0.039). Participants receiving SIM had a 33% reduction in postoperative complication rate (95% confidence interval [CI], 1-64; p=0.060) and a 39% reduction in infection rate (95% CI, 8-70; p=0.027) during late-phase recovery. The small sample size limits the study findings. PATIENT SUMMARY: Results show that the immune response to surgery and late infection rates differ between radical cystectomy patients receiving specialized immunonutrition versus oral nutrition supplement in the perioperative period.
