RESUMEN
The quantum adiabatic method, which maintains populations in their instantaneous eigenstates throughout the state evolution, is an established and often a preferred choice for state preparation and manipulation. Although it minimizes the driving cost significantly, its slow speed is a severe limitation in noisy intermediate-scale quantum era technologies. Since adiabatic paths are extensive in many physical processes, it is of broader interest to achieve adiabaticity at a much faster rate. Shortcuts to adiabaticity techniques, which overcome the slow adiabatic process by driving the system faster through non-adiabatic paths, have seen increased attention recently. The extraordinarily long lifetime of the long-lived singlet states (LLS) in nuclear magnetic resonance (NMR), established over the past decade, has opened several important applications ranging from spectroscopy to biomedical imaging. Various methods, including adiabatic methods, are already being used to prepare LLS. In this article, we report the use of counterdiabatic driving (CD) to speed up LLS preparation with faster drives. Using NMR experiments, we show that CD can give stronger LLS order in shorter durations than conventional adiabatic driving.
RESUMEN
BACKGROUND: Through applied research and health care quality improvement, California has achieved a maternal mortality (MM) rate significantly lower than that measured nationally. However, Medicaid (Medi-Cal)-insured births in the state continue to experience disproportionate shares of MM and severe maternal morbidity (SMM), which often precedes death. Failure to engage the Medi-Cal community in this work may impede efforts to increase equity. METHODS: This community engagement project used deliberative democracy methods to engage stakeholders with lived experience in California's Medi-Cal perinatal care system to generate an actionable and specific agenda of recommendations to decrease MM and SMM in the Medi-Cal population. FINDINGS: A total of 37 Medi-Cal stakeholders-representing birthing people, providers, health plan administrators, and advocates-participated in longitudinal co-learning sessions on the topics of MM/SMM in Medi-Cal. Most of these stakeholders (75.7%) then participated in deliberation sessions. Deliberation recommendations fell into five distinct categories: Medi-Cal perinatal covered benefits, data collection and dissemination, patient experience and its link to care quality, Medi-Cal reimbursement rates, and accountability with respect to racism in perinatal care. Stakeholders identified the Medi-Cal system actors best positioned to implement specific recommendations to directly impact MM/SMM. CONCLUSIONS: This project demonstrates the feasibility and success of using deliberative democracy methods to generate local and community-generated solutions to critical problems in health equity. Active and engaged stakeholders were keen to identify both immediate actions and long-term research and quality improvement paradigm shifts to support birth equity in Medi-Cal.

California leads the nation with its relatively low rate of maternal deaths during pregnancy and the postpartum period. However, individuals insured via Medi-Cal suffer a disproportionate share of maternal deaths and severe complications at birth; within this group of publicly insured individuals, certain racial and/or ethnic groups have even higher rates of poor outcomes. The state can attribute part of its success in lowering rates of maternal mortality (MM) to the implementation of a data-driven statewide portfolio of quality improvement activities focused on the leading causes of maternal death. This quality improvement infrastructure has not previously been leveraged to respond in a focused way to the relatively large shares of MM and morbidity still seen in the Medi-Cal-insured population. B-CORE aimed to expand on existing statewide quality improvement efforts to effectively mitigate these adverse outcomes in Medi-Cal births by engaging Medi-Cal stakeholders.
RESUMEN
Homelessness, which refers to the lack of a fixed, regular, and adequate nighttime residence, is a pervasive public health issue. This article presents results from an implementation and outcome study of an ongoing permanent supportive housing (PSH) program-including service utilization and associated costs review-operated by a large not-for-profit Medicaid and Medicare managed care plan serving more than 1 million members in the Inland Empire area of Southern California. This PSH program combines a long-term housing subsidy with intensive case management services for adult plan members experiencing homelessness who have one or more chronic physical or behavioral health conditions and represent high utilizers of inpatient health care. The aim of this research was to determine whether programmatic costs incurred by the health plan supporting the PSH program were partially or fully offset by decreased costs attributable to health care utilization within the health system. The evaluation used a quasi-experimental research design with an observational control group. The authors differentiated the program's effect during the transitional period-that is, after program enrollment and prior to housing placement-from its effect during the period after members were housed. In addition, the authors present participant flow through the key program milestones (e.g., referral, enrollment, housing placement, program exit) and describe health care utilization and associated costs for members who exited the program. Finally, they report the PSH programmatic expenditures relative to the changes in health care costs to provide an overall picture of the intervention's benefits and costs to the health plan.
RESUMEN
Homelessness is a pervasive public health problem in the United States (U.S.). Under the U.S. Affordable Care Act, the nation's public health insurance program (Medicaid) was expanded to serve more individuals, including those experiencing homelessness. Coupled with changes in financial incentives designed to reduce healthcare costs, health plans, hospitals and large health systems have started to operate permanent supportive housing (PSH) programmes as a healthcare benefit. To better understand patient perceptions of care coordination in a PSH programme operated by a large health plan in Southern California, we conducted 22 semi-structured in-depth patient interviews between October and November 2019. Two coders analysed these data inductively and deductively, using pre-identified domains and open coding. Coding reliability and thematic saturation were also assessed. Findings indicated positive experiences with care coordination for physical health and social supports, such as food distribution and transportation. Identified service gaps included mental health support and help securing public assistance (e.g., cash benefits). Opportunities to enhance PSH care coordination were also identified, such as the need for a simplified approach. Hospitals, health plans and systems considering PSH programmes may look to these results for implementation guidance.

BACKGROUND: Sterilization is used by one-quarter of women in the United States for contraception and is a preferred birth control method among women with Medicaid. A history of coercive sterilization practices in the United States led to federal regulation of consent for Medicaid sterilization (including a mandated waiting period); this regulation can be a barrier to sterilization in Medicaid-insured women. This study aimed to develop a revised model of Medicaid sterilization policy grounded in the experiences of women impacted by current regulations. METHODS: This prospective study used in-depth interviews with 32 Medicaid-insured women who had obtained or tried to obtain sterilization to elicit recommendations regarding the Medicaid waiting period. Deliberative methods (a planning cell including 20 key community stakeholders) were used to evaluate women's recommendations and propose a revised policy for sterilization under Medicaid. RESULTS: In-depth interview data demonstrated that women were often not made aware of the 30-day waiting period during informed consent before sterilization. Once informed about the policy, women described the Medicaid waiting period as "unfair," because it did not apply to all women. After deliberating women's recommendations to change the policy, key stakeholders came to a consensus around replacing the current waiting period policy with an improved consent process that would acknowledge the problematic history of coercive sterilization. Participants could not endorse removing the waiting period altogether without evidence that the health system had shifted away from coercive sterilization practices. CONCLUSIONS: Using deliberative methods and the recommendations of women with Medicaid insurance, community stakeholders recommended developing a revised Medicaid sterilization consent policy that acknowledged the historical context of this procedure.

Integrated care with mental health clinicians embedded in medical departments remains rare despite evidence of the need and effectiveness of such a model. Comprehensive, efficacious, and meaningful health care requires adequate attention be paid to the physiologic and the psychological symptoms of the patient. In the obstetrics/gynecology setting, myriad psychosocial concerns routinely present and cannot be adequately addressed in the current systems of care. The need is there, providers and patients have shown preference for such a structure, and the outcomes are promising. This article outlines common patient concerns in such settings and discusses possible interventions.

OBJECTIVE: To evaluate the implementation of pharmacist-prescribed hormonal contraceptives in California after a recent expansion of pharmacists' scope of practice. METHODS: A probability sample of 480 licensed California retail pharmacies (stratified by nonrural or rural location and independent or chain status) was included in a cross-sectional "secret shopper" telephone survey assessing the availability of pharmacist-prescribed hormonal contraceptives and service details. Survey data were analyzed using weighted descriptive statistics, CIs, and Wald tests. RESULTS: Findings included data from 457 pharmacies (response rate 95.2%). Only 5.1% of pharmacies reported providing pharmacist-prescribed hormonal contraceptives (95% CI 2.9-7.2%). This proportion did not differ significantly between rural and nonrural pharmacies (P=.83) nor between independent and chain pharmacies (P=.40). Five of the 22 pharmacies that were providing pharmacist-prescribed hormonal contraceptives informed secret shoppers that all allowed hormonal methods were available; most of these pharmacies (77.3%) did proactively describe that a health history was required before receiving medications. Only half of pharmacies providing pharmacist-prescribed hormonal contraceptives would do so for minors although this was allowed by law. CONCLUSION: In the first year after statewide protocol implementation, only a small proportion of retail pharmacies across California has begun offering hormonal contraception services. In the absence of additional supportive legislation regarding reimbursement for pharmacist services, increases in scope of practice regulations to build a larger network of contraceptive providers may not be effective in increasing access to birth control.

PURPOSE: To evaluate whether exposure to MyFamilyPlan-a web-based preconception health education module-changes the proportion of women discussing reproductive health with providers at well-woman visits. DESIGN: Cluster randomized controlled trial. One hundred thirty participants per arm distributed among 34 clusters (physicians) required to detect a 20% change in the primary outcome. SETTING: Urban academic medical center (California). PARTICIPANTS: Eligible women were 18 to 45 years old, were English speaking, were nonpregnant, were able to access the Internet, and had an upcoming well-woman visit. E-mail and phone recruitment between September 2015 and May 2016; 292 enrollees randomized. INTERVENTION: Intervention participants completed the MyFamilyPlan module online 7 to 10 days before a scheduled well-woman visit; control participants reviewed standard online preconception health education materials. MEASURES: The primary outcome was self-reported discussion of reproductive health with the physician at the well-woman visit. Self-reported secondary outcomes were folic acid use, contraceptive method initiation/change, and self-efficacy score. ANALYSIS: Multilevel multivariate logistic regression. RESULTS: After adjusting for covariates and cluster, exposure to MyFamilyPlan was the only variable significantly associated with an increase in the proportion of women discussing reproductive health with providers (odds ratio: 1.97, 95% confidence interval: 1.22-3.19). Prespecified secondary outcomes were unaffected. CONCLUSION: MyFamilyPlan exposure was associated with a significant increase in the proportion of women who reported discussing reproductive health with providers and may promote preconception health awareness; more work is needed to affect associated behaviors.

OBJECTIVE: To use population data to identify patient characteristics associated with a postpartum maternal emergency department visit within 90 days of discharge after birth. METHODS: This retrospective cross-sectional study analyzed linked maternal discharge and emergency department data for all live California births from 2009 to 2011. The primary outcome was at least one emergency department visit within 90 days of hospital discharge after birth. Secondary outcomes included three or more visits within 90 days ("high utilization") and inpatient readmission. Independent variables included demographics (age, race or ethnicity, payer, income) and clinical characteristics (length of stay, antepartum complications, mode of delivery, and severe maternal morbidity at delivery). Multilevel logistic regression identified variables associated study outcomes; we validated the predictive model with a split-sample approach and receiver operating characteristic curve analysis. RESULTS: Of 1,071,232 deliveries included, 88,674 women (8.3%) visited the emergency department at least once in the 90 days after delivery discharge. Emergency department use was significantly associated with Medicaid insurance (adjusted odds ratio [OR] 2.15, 95% CI 2.08-2.21), age younger than 20 years (adjusted OR 2.08, 95% CI 1.98-2.19), severe maternal morbidity at delivery (adjusted OR 1.58, 95% CI 1.49-1.71), antepartum complications (adjusted OR 1.46, 95% CI 1.42-1.50), and cesarean delivery (adjusted OR 1.40, 95% CI 1.37-1.44). Approximately one fifth of visits occurred within 4 days of discharge, and more than half were within 3 weeks. High utilizers comprised 0.5% of the entire sample (5,171 women) and only 1.2% of women presenting for emergency department care were readmitted. Receiver operating curve model analysis using the validation sample supported predictive accuracy for postpartum emergency department use (area under the curve=0.95). CONCLUSION: One in 12 California women visited the emergency department in the first 90 days after postpartum discharge. Women at increased risk for postpartum emergency department use per our validated model (eg, low income, birth complications) may benefit from earlier scheduled postpartum visits.

INTRODUCTION: Preterm birth is the leading cause of U.S. infant morbidity and mortality; Medicaid enrollees disproportionately experience preterm deliveries. Data suggest that progesterone-an evidence-based therapy for preventing preterm birth-is not accessible to all eligible Medicaid beneficiaries. This study aimed to identify variation in progesterone coverage guidelines in a sample of state Medicaid managed care organizations (MMCOs). MATERIAL AND METHODS: Using a cross-sectional design, participation in a web-based survey was offered to 20 MMCO members of the Medicaid Health Plans of America. The survey assessed coverage guidelines for progesterone and associated interventions to prevent preterm birth. MMCOs identified key barriers in providing progesterone. Descriptive analyses were performed. RESULTS: Analyses included data from 18 plans providing coverage in 31 of the 39 states with MMCOs (response rate, 90.0%). Responding MMCOs were diverse: 55.6% were multistate, 33.3% were nonprofit, and 31.2% covered more than 1,000,000 lives. Most respondents (87.5%) covered branded progesterone, and 81.3% covered compounded progesterone. Prior authorization was required by most plans for branded progesterone (86.7%) or compounded progesterone (75.0%). The MMCO gestational age restrictions for initiating progesterone varied from 22 to 37 weeks of gestation, even within the same state. MMCO-identified barriers to providing progesterone included cost, lack of clinician knowledge of indications and coverage, and variation in billing procedures. DISCUSSION: Marked variation in MMCO coverage policies and procedures for progesterone and related interventions to prevent preterm birth was noted. IMPLICATIONS FOR PRACTICE AND POLICY: Standardizing MMCO coverage policies may be one way to improve access to evidence-based interventions that prevent preterm birth.

Introduction Despite strong evidence supporting the benefit of 17-alpha hydroxyprogesterone caproate (17P) in preventing recurrent preterm birth, this treatment still does not reach most eligible patients. This study sought to identify approaches to measuring the appropriate use of 17P, with the goal of helping health systems better monitor and improve the implementation of this intervention. Methods Semi-structured telephone interviews were used to gather data on measures for 17P use being developed and implemented by state team members participating in the Infant Mortality Collaborative Improvement and Innovation Network (IM CoIIN)-a national quality improvement initiative. Strengths and limitations of these measurement approaches were described. Results Six approaches to measuring 17P use to prevent preterm birth were identified: practice-level data, population-based surveys, three measures employing insurance claims with or without linked birth certificate data, and revised birth certificates. Each measure had particular strengths and limitations. Practice-level measures were useful in rapid-cycle improvement, but were not generalizable across sites. In contrast, population-based measures (i.e., surveys, claims) were useful for broad comparisons, but were limited in their timeliness, and in how accurately they identified candidates who were truly eligible for 17P. Additionally, such measures required complex data linkage and analytic capabilities. Discussion A variety of imperfect measures for the appropriate use of 17P are available. No "best" measure was identified-the optimal measurement option must fit the specific needs of a health agency. Better data infrastructure and harnessing information from integrated electronic health records could improve the quality of 17P use measurement for improvement efforts.

BACKGROUND: The Sustainable development goals (SDGs) have the potential to have a significant impact on maternal and child health through their commitments both to directly addressing health services and to improving factors that form the foundation of social determinants of health. To achieve change at scale, national laws and policies have a critical role to play in implementing the SDGs' commitments. One particular policy that could advance a range of SDGs and importantly improve maternal and infant health is paid parental leave. METHODS: This article analyzes literature on paid leave and related policies relevant to SDG 1 (poverty), SDG 3 (health), SDG 5 (gender equality), SDG 8 (decent work), and SDG 10 (inequality). In addition, this article presents global data on the prevalence of policies in all 193 UN Member States. RESULTS: A review of the literature finds that paid parental leave may support improvements across a range of SDG outcomes relevant to maternal and child health. Across national income levels, paid leave has been associated with lower infant mortality and higher rates of immunizations. In high-income countries, studies have found that paid leave increases exclusive breastfeeding and may improve women's economic outcomes. However, factors including the duration of leave, the wage replacement rate, and whether leave is made available to both parents importantly shape the impacts of paid leave policies. While most countries now offer at least some paid maternal leave, many provide less than the 6 months recommended for exclusive breastfeeding, and only around half as many provide paternal leave. CONCLUSIONS: To accelerate progress on the SDGs' commitments to maternal and child health, we should monitor countries' actions on enacting or strengthening paid leave policies. Further research is needed on the duration, wage replacement rate, and availability of leave before and after birth that would best support both child and parental health outcomes and social determinants of health more broadly. In addition, further work is needed to understand the extent to which paid leave policies extend to the informal economy, where the majority of women and men in low- and middle-income countries work.
RESUMEN
Each year in the United States, more than 500,000 neonates are born before 37 weeks of gestation. Women who have experienced a previous preterm birth are at high risk of recurrence. A weekly prenatal injection of 17α-hydroxyprogesterone caproate decreases the risk of recurrent preterm birth and is recommended from as early as 16 weeks of gestation in women carrying singleton pregnancies who have a history of spontaneous singleton preterm birth. A commonly used metric for public health program effectiveness is population coverage of an intervention. In the case of 17α-hydroxyprogesterone caproate, population coverage can be defined as the proportion of women who are eligible for 17α-hydroxyprogesterone caproate (ie, previous pregnancy complicated by spontaneous singleton preterm birth) who actually receive the intervention. To receive a full course of 17α-hydroxyprogesterone caproate, women must negotiate a complex series of steps that includes presenting early for prenatal care, being identified as eligible for 17α-hydroxyprogesterone caproate, being offered 17α-hydroxyprogesterone caproate, accepting 17α-hydroxyprogesterone caproate, and adhering to the weekly 17α-hydroxyprogesterone caproate dose schedule. We describe this series of steps as well potential solutions to increase 17α-hydroxyprogesterone caproate coverage.

Objectives This study aimed to understand the impact of a previous adverse infant outcome (AIO) on use of preconception care prior to a subsequent pregnancy. Methods Responses from the 2010 and 2012 Los Angeles Mommy and Baby Surveys were analyzed. Weighted multivariate logistic regression was employed to identify significant associations between having had a previous AIO (preterm delivery, low birth weight infant, stillbirth, or major birth defect) and receipt of preconception care prior to the most recent pregnancy. Select patient-level covariates were included: chronic disease, age, education level, race/ethnicity, country of birth, insurance status prior to pregnancy and pregnancy intent. Adjustment for missing responses was performed using multiple chained imputation. Results After controlling for covariates, having had a previous AIO was associated with an increased odds of having utilized preconception care in the most recent pregnancy (OR 1.237, p = 0.040). Per the final regression model, a woman reporting a previous AIO and an intended subsequent pregnancy had a 42.4 % likelihood of having used preconception care. Of these women, only 28.8 % reported doing so because of concern regarding a previous birth complication. Discussion Women reporting a previous AIO were more likely to have used preconception care in a subsequent pregnancy. The prevalence of preconception care utilization remained low overall. Pregnancy intent emerged as a strong secondary predictor; any concerted strategy to improve access to preconception care must include initiatives to help ensure that pregnancies are planned.

IMPORTANCE: Detailed information regarding perioperative risk and adverse events associated with Mohs micrographic surgery (MMS) can guide clinical management. Much of the data regarding complications of MMS are anecdotal or report findings from single centers or single events. OBJECTIVES: To quantify adverse events associated with MMS and detect differences relevant to safety. DESIGN, SETTING, AND PARTICIPANTS: Multicenter prospective inception cohort study of 21 private and 2 institutional US ambulatory referral centers for MMS. Participants were a consecutive sample of patients presenting with MMS for 35 weeks at each center, with staggered start times. EXPOSURE: Mohs micrographic surgery. MAIN OUTCOMES AND MEASURES Intraoperative and postoperative minor and serious adverse events. RESULTS: Among 20 821 MMS procedures, 149 adverse events (0.72%), including 4 serious events (0.02%), and no deaths were reported. Common adverse events reported were infections (61.1%), dehiscence and partial or full necrosis (20.1%), and bleeding and hematoma (15.4%). Most bleeding and wound-healing complications occurred in patients receiving anticoagulation therapy. Use of some antiseptics and antibiotics and sterile gloves during MMS were associated with modest reduction of risk for adverse events. CONCLUSIONS AND RELEVANCE: Mohs micrographic surgery is safe, with a very low rate of adverse events, an exceedingly low rate of serious adverse events, and an undetectable mortality rate. Common complications include infections, followed by impaired wound healing and bleeding. Bleeding and wound-healing issues are often associated with preexisting anticoagulation therapy, which is nonetheless managed safely during MMS. We are not certain whether the small effects seen with the use of sterile gloves and antiseptics and antibiotics are clinically significant and whether wide-scale practice changes would be cost-effective given the small risk reductions.

Ganoderma lucidum (Lingzhi or Reishi) is known as a bitter mushroom with remarkable health benefits. The active constituents found in mushrooms include polysaccharides, dietary fibers, oligosaccharides, triterpenoids, peptides and proteins, alcohols and phenols, mineral elements (such as zinc, copper, iodine, selenium, and iron), vitamins, and amino acids. The bioactive components found in the G. lucidum mushroom have numerous health properties to treat diseased conditions such as hepatopathy, chronic hepatitis, nephritis, hypertension, hyperlipemia, arthritis, neurasthenia, insomnia, bronchitis, asthma, gastric ulcers, atherosclerosis, leukopenia, diabetes, anorexia, and cancer. In spite of the voluminous literature available, G. lucidum is used mostly as an immune enhancer and a health supplement, not therapeutically. This review discusses the therapeutic potential of G. luidum to attract the scientific community to consider its therapeutic application where it can be worth pursuing.

Cancer is a major public health concern in both developed and developing countries. Several plant-derived anti-cancer agents including taxol, vinblastine, vincristine, the campothecin derivatives, topotecan, irinotecan and etoposide are in clinical use all over the world. Other promising anti-cancer agents include flavopiridol, roscovitine, combretastatin A-4, betulinic acid and silvestrol. From this list one can well imagine the predominance of polyphenols, flavonoids and their synthetic analogs in the treatment of ovarian, breast, cervical, pancreatic and prostate cancer. Flavonoids present in human diet comprise many polyphenolic secondary metabolites with broad-spectrum pharmacological activities including their potential role as anti-cancer agents. A positive correlation between flavonoids-rich diet (from vegetables and fruits) and lower risk of colon, prostate and breast cancers lead to a question that whether flavonoids mediate the protective effects as chemopreventive agents or can interact with different genes and proteins to play role in chemotherapy. The current review emphasizes onto the therapeutic potential of flavonoids and their synthetic analogs as anti-cancer agents by providing new insights into the factors, regulation and molecular mechanisms along with their significant protein interactions.
