Validity of Partner Reports of Recent Condomless Sex.

BACKGROUND: Prostate-specific antigen (PSA), a biomarker of vaginal semen exposure, is less susceptible to bias than self-reported condom use behaviors. We examined the agreement of self-reported recent condomless sex (RCS) within couples and how these reports related to PSA detection. METHODS: We analyzed data from a study conducted in Vietnam, 2017 to 2020, of 500 different-sex couples using condoms and no other contraceptive method to prevent pregnancy for 6 months. We assessed enrollment and 6-month data from vaginal swabs and questionnaires from both partners. We calculated Prevalence-Adjusted Bias-Adjusted Kappa (PABAK) to evaluate agreement of men's and women's reports. Among couples with detected PSA, we assessed partner concordance of RCS reporting. RESULTS: At enrollment (n = 499), 79.8% of couples reported no RCS, 16.4% reported RCS, and 3.8% had partner-discordant reports (PABAK, 0.93; 95% confidence interval, 0.91-0.97). At 6 months (n = 472), 91.7% reported no RCS, 5.7% reported RCS, and 2.5% had partner-discordant reports (PABAK, 0.98; 95% confidence interval, 0.96-1.0). Among couples with detected PSA at baseline (11%, n = 55), 36% reported no RCS, 55% reported RCS, and 6% had discordant reports; at 6 months (6.6%, n = 31), 58% reported no RCS, 35% reported RCS, and 3% had discordant reports. CONCLUSIONS: We observed high agreement regarding condomless sex within couples in a population using condoms as contraception in Vietnam; however, a high proportion of couples with detected PSA had both partners reporting no RCS, indicating that concordant reporting of no RCS does not indicate lack of semen exposure.

The ERUS course on robot-assisted kidney transplantation.

PURPOSE: Robot-assisted kidney transplantation (RAKT) is being increasingly performed at selected referral institutions worldwide. Yet, surgical training in RAKT is still unstructured and not grounded into formal credentialing courses including simulation, lab facilities, and modular training with animal models. As such, developing standardized, modular training programs is warranted to provide surgeons with the RAKT-specific skillset needed for a "safe" learning curve. METHODS: The 3-day course on RAKT developed at the EAU Skills Center in Orsi Academy was designed as a standardized, modular, step-by-step approach aiming to provide theoretical and practical skills. The course is held by expert proctors with extensive experience in RAKT. To maximize the course's usefulness, a solid knowledge of robotics and transplantation is desirable for participants. RESULTS: From January 2016 to July 2023, 87 surgeons from 23 countries (of which 36% from extra-European countries) participated in the RAKT course performed at the EAU Skills Center in Orsi Academy. Of these, 58/87 (67%) were urologists, while 27/87 (31%) were general surgeons and 2/87 (2%) were vascular surgeons. To date, 18 participants (20.6%) are actively involved in RAKT programs at institutions included in the European Association of Urology (EAU) Robotic Urology Section (ERUS)-RAKT network. CONCLUSION: Leveraging the potential of simulation, wet-lab training, live porcine models, and experienced proctors, the RAKT course performed at the EAU Skills Center in Orsi Academy represents the first structured teaching effort aiming to offer surgeons a full immersion in RAKT to train the core technical skills.

Prevalence and correlates of very rapid repeat pregnancy: Pregnancy Risk Assessment Monitoring System, United States, 2009-2020.

BACKGROUND: Most rapid repeat pregnancies, defined as those occurring within 18 months of a previous birth, are unintended. These pregnancies are associated with later initiation of prenatal care and are more common among people with lower socio-economic status and among racially and ethnically minoritised populations. OBJECTIVES: To assess prevalence and correlate pregnancies occurring in the immediate period after a live birth in the United States, using the Pregnancy Risk Assessment Monitoring System (PRAMS). METHODS: We assessed data from the 2009-2020 PRAMS, a population-based survey of perinatal maternal characteristics of mothers of liveborn infants in US locations. We assessed pregnancies reported during the immediate postpartum period (approximately 2-6 months post-delivery), and term this 'very rapid repeat pregnancy' (VRRP). We assessed the adjusted prevalence of VRRP from 2009 to 2020. From 2016 to 2020, we calculated adjusted prevalence ratios (aPR) with 95% confidence intervals (CI) for maternal characteristics. RESULTS: The adjusted prevalence of VRRP ranged from 0.38% (95% CI: 0.29, 0.48) in 2009 to 0.76% (95% CI: 0.61, 0.91) in 2020. Demographic characteristics associated with VRRP included younger age, lower educational attainment, and being unmarried. Black mothers had a higher prevalence of VRRP compared to white mothers. Mothers who attended a healthcare visit in the 12 months preconception had a lower prevalence of VRRP as did mothers who attended a postpartum check-up, compared to their counterparts without these visits. Among those receiving prenatal care, mothers whose prenatal healthcare provider asked about postpartum contraception birth had a lower prevalence of VRRP, compared to those not asked about postpartum contraception. CONCLUSIONS: VRRP appeared to increase over time in 2009-2020. Mothers who are younger, Black, have lower educational attainment, or who did not attend healthcare visits before or after pregnancy had a higher prevalence of VRRP and may comprise a population who would benefit from additional family planning resources.

Indole-3-Propionic Acid, a Gut Microbiota-Derived Tryptophan Metabolite, Promotes Endothelial Dysfunction Impairing Purinergic-Induced Nitric Oxide Release in Endothelial Cells.

Different gut microbiota-derived metabolites influence cardiovascular function, and, among all, the role of indole-3-propionic acid (IPA), from tryptophan metabolism, shows controversial effects. The aim of this study was to evaluate its role in endothelial dysfunction. IPA effects were studied on bovine aortic endothelial cells (BAE-1). First, IPA cytotoxicity was evaluated by an MTS assay. Then, the levels of intracellular reactive oxygen species (ROS) were evaluated by a microplate reader or fluorescence microscopy with the CellROX® Green probe, and nitric oxide (NO) production was studied by fluorescence microscopy with the DAR4M-AM probe after acute or chronic treatment. Finally, immunoblotting analysis for endothelial nitric oxide synthase (eNOS) phosphorylation (p-eNOS) was performed. In BAE-1, IPA was not cytotoxic, except for the highest concentration (5 mM) after 48 h of treatment, and it showed neither oxidant nor antioxidant activity. However, the physiological concentration of IPA (1 µM) significantly reduced NO released by adenosine triphosphate (ATP)-stimulated BAE-1. These last data were confirmed by Western blot analysis, where IPA induced a significant reduction in p-eNOS in purinergic-stimulated BAE-1. Given these data, we can speculate that IPA negatively affects the physiological control of vascular tone by impairing the endothelial NO release induced by purinergic stimulation. These results represent a starting point for understanding the mechanisms underlying the relationship between gut microbiota metabolites and cardiometabolic health.

Multi-omic analysis shows REVEILLE clock genes are involved in carbohydrate metabolism and proteasome function.

Plants are able to sense changes in their light environments, such as the onset of day and night, as well as anticipate these changes in order to adapt and survive. Central to this ability is the plant circadian clock, a molecular circuit that precisely orchestrates plant cell processes over the course of a day. REVEILLE (RVE) proteins are recently discovered members of the plant circadian circuitry that activate the evening complex and PSEUDO-RESPONSE REGULATOR genes to maintain regular circadian oscillation. The RVE8 protein and its two homologs, RVE 4 and 6 in Arabidopsis (Arabidopsis thaliana), have been shown to limit the length of the circadian period, with rve 4 6 8 triple-knockout plants possessing an elongated period along with increased leaf surface area, biomass, cell size, and delayed flowering relative to wild-type Col-0 plants. Here, using a multi-omics approach consisting of phenomics, transcriptomics, proteomics, and metabolomics we draw new connections between RVE8-like proteins and a number of core plant cell processes. In particular, we reveal that loss of RVE8-like proteins results in altered carbohydrate, organic acid, and lipid metabolism, including a starch excess phenotype at dawn. We further demonstrate that rve 4 6 8 plants have lower levels of 20S proteasome subunits and possess significantly reduced proteasome activity, potentially explaining the increase in cell-size observed in RVE8-like mutants. Overall, this robust, multi-omic dataset provides substantial insight into the far-reaching impact RVE8-like proteins have on the diel plant cell environment.

Perinatal serotonergic manipulation shapes anhedonic and cognitive behaviors in a sex- and age-dependent manner: Identification of related biological functions at central and peripheral level.

Poor knowledge about psychiatric disorders often results in similar diagnoses for patients with different symptoms, thus limiting the effectiveness of the available medications. As suggested by several lines of evidence, to improve these shortcomings, it is essential to identify biomarkers associated with specific symptoms and to stratify patients into more homogeneous populations taking a further step toward personalized medicine. Here, we aimed to associate specific behavioral phenotypes with specific molecular alterations by employing an animal model based on the pharmacological manipulation of the serotonergic system, which mimics a condition of vulnerability to develop psychiatric disorders. In particular, we treated female and male rats with fluoxetine (FLX 15 mg/kg dissolved in drinking water) during prenatal or early postnatal life, and we evaluated different pathological-like phenotypes (cognitive deficit, anhedonia, and anxiety) by exposing the rats to a battery of behavioral tests during adolescence and adulthood. In addition, we carried out molecular analyses on specific brain areas and in the blood. Our results showed that perinatal FLX administration determined age- and sex-dependent effects, with males being more sensitive to prenatal manipulation and manifesting anhedonic-like behavior and females to early postnatal exposure, exhibiting cognitive deficits and a less anxious phenotype. Furthermore, we identified, peripherally and centrally, biological functions altered by perinatal serotonin modulation regardless of the timing of exposure and sex, and other pathways specific for the pathological-like phenotypes. The results presented here provide new insights into potential biomarkers associated with specific behavioral phenotypes that may be useful for broadening knowledge about psychiatric conditions.

Persisting Effects in Daphnia magna Following an Acute Exposure to Flowback and Produced Waters from the Montney Formation.

Hydraulic fracturing extracts oil and gas through the injection of water and proppants into subterranean formations. These injected fluids mix with the host rock formation and return to the surface as a complex wastewater containing salts, metals, and organic compounds, termed flowback and produced water (FPW). Previous research indicates that FPW is toxic to Daphnia magna (D. magna), impairing reproduction, molting, and maturation time; however, recovery from FPW has not been extensively studied. Species unable to recover have drastic impacts on populations on the ecological scale; thus, this study sought to understand if recovery from an acute 48 h FPW exposure was possible in the freshwater invertebrate, D. magna by using a combination of physiological and molecular analyses. FPW (0.75%) reduced reproduction by 30% and survivorship to 32% compared to controls. System-level quantitative proteomic analyses demonstrate extensive perturbation of metabolism and protein transport in both 0.25 and 0.75% FPW treatments after a 48 h FPW exposure. Collectively, our data indicate that D. magna are unable to recover from acute 48 h exposures to ≥0.25% FPW, as evidence of toxicity persists for at least 19 days post-exposure. This study highlights the importance of considering persisting effects following FPW remediation when modeling potential spill scenarios.

Resilience to chronic mild stress-induced anhedonia preserves the ability of the ventral hippocampus to respond to an acute challenge.

Stress is a major precipitating factor for psychiatric disorders and its effects may depend on its duration and intensity. Of note, there are differences in individual susceptibility to stress, with some subjects displaying vulnerability and others showing resistance. Furthermore, the ability to react to stressful-life events can alter the response to a subsequent new stressor. Hence, we investigated whether the vulnerability and resilience to the chronic mild stress (CMS) paradigm, in terms of the hedonic phenotype, are paralleled by a different response when facing a novel acute challenge. Specifically, rats submitted to CMS were stratified based on their sucrose intake into vulnerable (anhedonic rats showing reduce intake of sucrose) and resilient (rats not showing the anhedonic-like behavior) subgroups and then further exposed to an acute restraint stress (ARS). Then, neuronal activation was investigated by measuring the gene expression of early immediate (IEG) genes such as Arc and Cfos and early response (ERG) genes, such as Gadd45ß, Sgk1, Dusp1, and Nr4a1, in brain regions that play a crucial role in the stress response. We found that resilient rats preserve the ability to increase ERG expression following the ARS selectively in the ventral hippocampus. Conversely, such ability is lost in vulnerable rats. Interestingly, the recovery from the anhedonic phenotype observed in vulnerable rats after 3 weeks of rest from the CMS procedure also parallels the restoration of the ability to adequately respond to the challenge. In conclusion, these findings support the role of the ventral subregion of the hippocampus in the management of both chronic and acute stress response and point to this brain subregion as a critical target for a potential therapeutic strategy aimed at promoting stress resilience.

Free, but at what cost? How US crisis pregnancy centres provide services.

In the USA, the most popular form of anti-abortion activism, crisis pregnancy centres (CPCs), provide a variety of services to prevent abortions. Moving beyond debate about misinformation and the ethics of CPCs, this study considers the services they provide and given their popularity among state legislatures, their connection to the state. Using interviews with ten CPC staff in Ohio (a state providing support to CPCs) and supplemental data from both state and CPC organisations, we find three relevant themes. First, CPC services reflect ideas about personal responsibility and Christianity held by the CPC staff. Second, we show that CPCs have assumed a variety of state duties (e.g. pregnancy testing and parenting classes), appealing to lawmakers in conservative states eager to transfer responsibility for disadvantaged residents to other entities. Finally, we consider the future direction of CPCs, highlighting tension between organisational goals (focusing on abortion prevention) and the on-the-ground experience of CPC staff (where non-pregnant clients need material aid). Drawing theoretical connections between CPC staff and social service workers sheds light on whose responsibility it is to address poverty in a post-welfare era.

Modulation of Endothelial Function by TMAO, a Gut Microbiota-Derived Metabolite.

Endothelial function is essential in the maintenance of systemic homeostasis, whose modulation strictly depends on the proper activity of tissue-specific angiocrine factors on the physiopathological mechanisms acting at both single and multi-organ levels. Several angiocrine factors take part in the vascular function itself by modulating vascular tone, inflammatory response, and thrombotic state. Recent evidence has outlined a strong relationship between endothelial factors and gut microbiota-derived molecules. In particular, the direct involvement of trimethylamine N-oxide (TMAO) in the development of endothelial dysfunction and its derived pathological outcomes, such as atherosclerosis, has come to light. Indeed, the role of TMAO in the modulation of factors strictly related to the development of endothelial dysfunction, such as nitric oxide, adhesion molecules (ICAM-1, VCAM-1, and selectins), and IL-6, has been widely accepted. The aim of this review is to present the latest studies that describe a direct role of TMAO in the modulation of angiocrine factors primarily involved in the development of vascular pathologies.

Chronic N-Acetyl-Cysteine Treatment Enhances the Expression of the Immediate Early Gene Nr4a1 in Response to an Acute Challenge in Male Rats: Comparison with the Antidepressant Venlafaxine.

Despite several antidepressant treatments being available in clinics, they are not effective in all patients. In recent years, N-acetylcysteine (NAC) has been explored as adjunctive therapy for many psychiatric disorders, including depression, for its antioxidant properties. Given the promising efficacy of this compound for the treatment of such pathologies, it is fundamental to investigate, at the preclinical level, the ability of the drug to act in the modulation of neuroplastic mechanisms in basal conditions and during challenging events in order to highlight the potential features of the drug useful for clinical efficacy. To this aim, adult male Wistar rats were treated with the antidepressant venlafaxine (VLX) (10 mg/kg) or NAC (300 mg/kg) for 21 days and then subjected to 1 h of acute restraint stress (ARS). We found that NAC enhanced the expression of several immediate early genes, markers of neuronal plasticity in the ventral and dorsal hippocampus, prefrontal cortex and amygdala, and in particular it mediated the acute-stress-induced upregulation of Nr4a1 expression more than VLX. These data suggested the ability of NAC to induce coping strategies to face external challenges, highlighting its potential for the improvement of neuroplastic mechanisms for the promotion of resilience, in particular via the modulation of Nr4a1.

Developmentally regulated mitochondrial biogenesis and cell death competence in maize pollen.

BACKGROUND: Cytoplasmic male sterility (CMS) is a maternally inherited failure to produce functional pollen that most commonly results from expression of novel, chimeric mitochondrial genes. In Zea mays, cytoplasmic male sterility type S (CMS-S) is characterized by the collapse of immature, bi-cellular pollen. Molecular and cellular features of developing CMS-S and normal (N) cytoplasm pollen were compared to determine the role of mitochondria in these differing developmental fates. RESULTS: Terminal deoxynucleotidyl transferase dUTP nick end labeling revealed both chromatin and nuclear fragmentation in the collapsed CMS-S pollen, demonstrating a programmed cell death (PCD) event sharing morphological features with mitochondria-signaled apoptosis in animals. Maize plants expressing mitochondria-targeted green fluorescent protein (GFP) demonstrated dynamic changes in mitochondrial morphology and association with actin filaments through the course of N-cytoplasm pollen development, whereas mitochondrial targeting of GFP was lost and actin filaments were disorganized in developing CMS-S pollen. Immunoblotting revealed significant developmental regulation of mitochondrial biogenesis in both CMS-S and N mito-types. Nuclear and mitochondrial genome encoded components of the cytochrome respiratory pathway and ATP synthase were of low abundance at the microspore stage, but microspores accumulated abundant nuclear-encoded alternative oxidase (AOX). Cytochrome pathway and ATP synthase components accumulated whereas AOX levels declined during the maturation of N bi-cellular pollen. Increased abundance of cytochrome pathway components and declining AOX also characterized collapsed CMS-S pollen. The accumulation and robust RNA editing of mitochondrial transcripts implicated translational or post-translational control for the developmentally regulated accumulation of mitochondria-encoded proteins in both mito-types. CONCLUSIONS: CMS-S pollen collapse is a PCD event coincident with developmentally programmed mitochondrial events including the accumulation of mitochondrial respiratory proteins and declining protection against mitochondrial generation of reactive oxygen species.

Housing Stability and Access to General Healthcare and Reproductive Healthcare Among Women in Ohio.

BACKGROUND: The relationship between housing instability and reproductive healthcare is understudied. We examined the association between housing insecurity and access and utilization of general healthcare, contraceptive healthcare, and abortion care. METHODS: Using data from a population-representative survey of adult reproductive-age Ohio women (N = 2,529), we assessed housing insecurity (not paying rent/mortgage on time in the past year). We examined associations between housing insecurity and the following outcomes: (1) not being able to access general healthcare in the past year; (2) experiencing delays or difficulties in accessing contraceptive healthcare in the past year; and (3) ever having an abortion. We used unadjusted and adjusted logistic regression models. We selected confounders a priori and included age, socioeconomic status, and healthcare status. RESULTS: Overall, 10.6% of Ohio women of adult reproductive age experienced housing insecurity. Approximately 27.5% of respondents were not able to access general healthcare and 10.4% experienced delays or difficulties in accessing contraceptive care. Compared to housing-secure respondents, housing-insecure women were less able to access general healthcare (adjusted odds ratio [aOR]:2.16; 95% confidence interval [CI]:1.45-3.23) and more likely to experience delays or difficulties when accessing contraceptive care (aOR:1.74; 95% CI:1.00-3.04). Insecure housing was not statistically associated with ever having an abortion (aOR:1.76; 95% CI:0.93-3.34). CONCLUSIONS: In this study, recent housing insecurity was associated with poorer access to general and contraceptive healthcare. Studies utilizing multidimensional measures of housing insecurity and other material insecurity measures are needed to further explore the relationship between material insecurity and access to general and contraceptive care.

Trimethylamine N-Oxide (TMAO) Impairs Purinergic Induced Intracellular Calcium Increase and Nitric Oxide Release in Endothelial Cells.

Trimethylamine N-oxide (TMAO) is a diet derived compound directly introduced through foodstuff, or endogenously synthesized from its precursors, primarily choline, L-carnitine, and ergothioneine. New evidence outlines high TMAO plasma concentrations in patients with overt cardiovascular disease, but its direct role in pathological development is still controversial. The purpose of the study was to evaluate the role of TMAO in affecting key intracellular factors involved in endothelial dysfunction development, such as reactive oxygen species, mitochondrial health, calcium balance, and nitric oxide release using bovine aortic endothelial cells (BAE-1). Cell viability and oxidative stress indicators were monitored after acute and prolonged TMAO treatment. The role of TMAO in interfering with the physiological purinergic vasodilatory mechanism after ATP stimulation was defined through measurements of the rise of intracellular calcium, nitric oxide release, and eNOS phosphorylation at Ser1179 (eNOSSer1179). TMAO was not cytotoxic for BAE-1 and it did not induce the rise of reactive oxygen species and impairment of mitochondrial membrane potential, either in the basal condition or in the presence of a stressor. In contrast, TMAO modified the purinergic response affecting intracellular ATP-induced calcium increase, nitric oxide release, and eNOSSer1179. Results obtained suggest a possible implication of TMAO in impairing the endothelial-dependent vasodilatory mechanism.

Three-dimensional reconstruction and intraoperative ultrasonography: Crucial tools to safely approach highly complex renal masses.

PURPOSE: Robot-assisted partial nephrectomy (RAPN) is rapidly increasing its role in the nephron-sparing surgery setting (1). The recent introduction of technological advancements is leading more experienced surgeons to approach complex renal mass with a conservative intent (2, 3). In particular, three-dimensional reconstruction and the use of intraoperative ultrasonography are gaining attention as crucial tools to safely and effectively approach complex cases (4, 5). We aimed to video-report the management of highly complex renal mass treated with RAPN, focusing on preoperative surgical planning and intraoperative technical nuances. MATERIALS AND METHODS: A 73-year-old male patient was referred to our institution for an incidental detection of a 70 mm diameter, completely endophytic, hilar renal mass (PADUA score 13, RENAL score 11a). Contrast-enhanced CT scan images were processed by M3DICS (Turin, Italy) and used to obtain a 3D virtual model. RAPN was performed by a highly experienced surgeon using Da Vinci Si robotic platform with a three-arm configuration. RESULTS: The overall operative time was 114 min, with a warm ischemia time of 16 min. No intraoperative or postoperative complications were recorded. According to the SIB score, the pure enucleation excision strategy was performed. Histopathological analysis revealed a pT3a low-grade oncocytic kidney tumor with negative surgical margins. with negative surgical margins. At 24-months follow up, no local or systemic recurrence was detected. CONCLUSIONS: Conservative management of complex renal masses is challenging with a highly nuanced decision-making process. In this regard, preoperative 3D models and intraoperative ultrasound (US) guidance play a pivotal role to develop a tailored surgical strategy according to patient' and tumor's characteristics.

Natural polymorphisms in a pair of NSP2 homoeologs can cause loss of nodulation in peanut.

Microbial symbiosis in legumes is achieved through nitrogen-fixing root nodules, and these are important for sustainable agriculture. The molecular mechanisms underlying development of root nodules in polyploid legume crops are largely understudied. Through map-based cloning and QTL-seq approaches, we identified a pair of homoeologous GRAS transcription factor genes, Nodulation Signaling Pathway 2 (AhNSP2-B07 or Nb) and AhNSP2-A08 (Na), controlling nodulation in cultivated peanut (Arachis hypogaea L.), an allotetraploid legume crop, which exhibited non-Mendelian and Mendelian inheritance, respectively. The segregation of nodulation in the progeny of Nananbnb genotypes followed a 3:1 Mendelian ratio, in contrast to the 5:3~1:1 non-Mendelian ratio for nanaNbnb genotypes. Additionally, a much higher frequency of the nb allele (13%) than the na allele (4%) exists in the peanut germplasm collection, suggesting that Nb is less essential than Na in nodule organogenesis. Our findings reveal the genetic basis of naturally occurred non-nodulating peanut plants, which can be potentially used for nitrogen fixation improvement in peanut. Furthermore, the results have implications for and provide insights into the evolution of homoeologous genes in allopolyploid species.

Passage of abortion ban and women's accurate understanding of abortion legality.

BACKGROUND: Legislative and judicial procedures related to banning abortion after 6 weeks of gestation in Ohio occurred from November 2018 to July 2019. These activities could have increased the belief that abortion has become illegal even though the 6-week abortion ban has never been in effect to date. OBJECTIVE: We sought to determine the prevalence and correlates of holding the belief that abortion is illegal in Ohio and to evaluate whether this belief increased over the time in which the 6-week abortion ban was introduced, passed twice, and then blocked in Ohio. STUDY DESIGN: We analyzed data from the first wave of the Ohio Survey of Women, a population-based survey of adult, reproductive-aged Ohioan women conducted from October 2018 to June 2019. During each of the 8 survey months, a median of 240 women (range, 70-761) completed the survey, including the survey question "Based on what you know or have heard, is it legal to get an abortion in your state?" We used multivariable logistic regression to assess the prevalence and correlates of believing that abortion is illegal in the state of Ohio. In addition, we used multinomial logistic regression to evaluate whether this belief increased over the interval during which women completed the survey, which roughly corresponded to the interval marked by legislative and judicial activities surrounding the 6-week abortion ban. RESULTS: Most of the 2359 participants understood that abortion is legal in the state of Ohio (64.0%) with the remainder believing it to be illegal (9.8%) or being unsure (26.2%). Correlates of believing abortion to be illegal included younger age, lower socioeconomic status, never married or married status, and Black, non-Hispanic race and ethnicity. Being unsure about legality did not change over time; however, the proportion of women who believed that abortion is illegal increased from the first month (4.5%) to the last month (15.9%) of the study period. Each additional study month was associated with a 17% increase in the odds of believing abortion to be illegal, in both unadjusted and adjusted models (odds ratio, 1.17; 95% confidence interval, 1.08-1.27). CONCLUSION: Attempts to restrict abortion access could contribute to women mistakenly believing that abortion is illegal despite it being unsuccessful.

Mediterranean diet consumption affects the endocannabinoid system in overweight and obese subjects: possible links with gut microbiome, insulin resistance and inflammation.

PURPOSE: To investigate whether a Mediterranean diet (MD) affected the plasma concentrations of endocannabinoids (ECs), N-acylethanolamines (NAEs) and their specific ratios in subjects with lifestyle risk factors for metabolic diseases. To identify the relationship between circulating levels of these compounds and gut microbiome, insulin resistance and systemic inflammation. METHODS: A parallel 8-week randomised controlled trial was performed involving 82 overweight and obese subjects aged (mean ± SEM) 43 ± 1.4 years with a BMI of 31.1 ± 0.5 kg/m2, habitual Western diet (CT) and sedentary lifestyle. Subjects were randomised to consume an MD tailored to their habitual energy and macronutrient intake (n = 43) or to maintain their habitual diet (n = 39). Endocannabinoids and endocannabinoid-like molecules, metabolic and inflammatory markers and gut microbiome were monitored over the study period. RESULTS: The MD intervention lowered plasma arachidonoylethanolamide (AEA, p = 0.02), increased plasma oleoylethanolamide/palmitoylethanolamide (OEA/PEA, p = 0.009) and OEA/AEA (p = 0.006) and increased faecal Akkermansia muciniphila (p = 0.026) independent of body weight changes. OEA/PEA positively correlated with abundance of key microbial players in diet-gut-health interplay and MD adherence. Following an MD, individuals with low-plasma OEA/PEA at baseline decreased homeostatic model assessment of insulin resistance index (p = 0.01), while individuals with high-plasma OEA/PEA decreased serum high-sensitive C-reactive protein (p = 0.02). CONCLUSIONS: We demonstrated that a switch from a CT to an isocaloric MD affects the endocannabinoid system and increases A. muciniphila abundance in the gut independently of body weight changes. Endocannabinoid tone and microbiome functionality at baseline drives an individualised response to an MD in ameliorating insulin sensitivity and inflammation.

Role of temporal discounting in a conditional cash transfer (CCT) intervention to improve engagement in the prevention of mother-to-child transmission (PMTCT) cascade.

BACKGROUND: Temporal discounting, the tendency of individuals to discount future costs and benefits relative to the present, is often associated with greater engagement in risky behaviors. Incentives such as conditional cash transfers (CCTs) have the potential to counter the effects of high discount rates on health behaviors. METHODS: With data from a randomized trial of a CCT intervention among 434 HIV-positive pregnant women in the Democratic Republic of Congo, we used binomial models to assess interactions between discount rates (measured using a delay-discounting task) and the intervention. The analysis focused on two outcomes: 1) retention in HIV care, and 2) uptake of prevention of mother-to-child transmission (PMTCT) services. RESULTS: The effect of high discount rates on retention was small, and we did not observe evidence of interaction between high discount rates and CCT on retention. However, our findings suggest that CCT may mitigate the negative effect of high discount rates on uptake of PMTCT services (interaction contrast (IC): 0.18, 95% CI: - 0.09, 0.44). CONCLUSIONS: Our findings provide evidence to support the continued use of small, frequent incentives, to motivate improved uptake of PMTCT services, especially among women exhibiting high rates of temporal discounting. TRIAL REGISTRATION: Clinicaltrials.gov number NCT01838005 , April 23, 2013.

Contraceptive knowledge among women at risk of unintended pregnancy in Kingston, Jamaica.

Low contraceptive knowledge may limit contraception initiation or continuation and, consequently, could represent an important, modifiable cause of unintended pregnancy. The objective of this analysis was to identify correlates of knowledge among women at risk of unintended pregnancy. We analyzed data from a study of 222 young women attending a public clinic in Kingston in November 2018 to March 2019. We measured contraceptive knowledge with seven questions on method reversibility, ability to use covertly, contraindications, and side effects. We used multivariable linear regression to evaluate the correlates of summary knowledge scores and report beta coefficients, which represent differences in mean summary knowledge scores. The mean knowledge score was low (2.7; range = 0-7). Only 30.2% of the participants correctly identified intrauterine devices as more effective than oral contraception, male condoms, and withdrawal. Women who reported that their provider discussed contraception scored higher (adjusted ß = 0.37, p = 0.05) than those not reporting this. Women who perceived implants as very/mostly safe scored higher (adjusted ß = 0.45, p = 0.01) than those perceiving the device as mostly/very unsafe. Finally, compared to contraception non-users, women using less-effective contraception had a lower score (adjusted ß = -0.40, p = 0.04) while those using effective contraception did not differ in scores (ß = -0.30, p = 0.18). Overall, we found poor contraceptive knowledge among young women in Kingston. Providers appeared to hold an important role in women's understanding of contraception.
