RESUMEN

BACKGROUND: Cisgender women account for 1 of every 5 new US HIV diagnoses, with most cases (85%) attributed to heterosexual contact. HIV preexposure prophylaxis is an effective prevention strategy; however, preexposure prophylaxis awareness and prescriptions among women are low. OBJECTIVE: This study aimed to increase preexposure prophylaxis counseling and uptake among cisgender women attending obstetrics and gynecology clinics. STUDY DESIGN: The study included 3 obstetrics and gynecology clinics within a single health system in a high HIV prevalence region. There were 3 phases: baseline (the 3-month period before the clinical trial that included provider education and training of a registered nurse about preexposure prophylaxis), clinical trial (the 3-month period during which eligible patients were randomized to an active control or preexposure prophylaxis registered nurse intervention), and maintenance (the 3-month period after the trial ended). Electronic medical record clinical decision support tools were available to both arms during the clinical trial, which included best practice alerts, order sets, progress note templates, and written and video preexposure prophylaxis educational materials for patients. In the intervention arm, a preexposure prophylaxis nurse contacted and counseled patients and was equipped to prescribe preexposure prophylaxis. Moreover, this study evaluated the phases through the "reach, effectiveness, adoption, implementation, and maintenance" framework. The primary outcome of the study was effectiveness (eg, percentage of eligible patients with documented HIV prevention counseling in the electronic medical record or preexposure prophylaxis prescriptions). The secondary outcomes included reach (eg, percentage of best practice alerts that providers acted on or the percentage of eligible patients who spoke with the preexposure prophylaxis registered nurse), adoption (eg, percentage of eligible patients with a best practice alert that triggered or the percentage of eligible patients the preexposure prophylaxis registered nurse attempted to contact), and maintenance (eg, percentage of patients with documented HIV prevention counseling or preexposure prophylaxis prescriptions during the maintenance phase). RESULTS: There were 904 unique patients in all phases with a mean age of 28.8±7.7 years, and 416 patients (46%) were pregnant; moreover, 436 patients were randomized in the clinical trial phase. Concerning reach and adoption, best practice alerts were triggered for 100% of eligible encounters; however, the providers acted on 52% of them. The preexposure prophylaxis nurse attempted to contact every patient and successfully spoke with 81.2% of them in the preexposure prophylaxis registered nurse arm. Concerning effectiveness, there were significantly more patients counseled about preexposure prophylaxis in the preexposure prophylaxis registered nurse group than in the active control group (66.5% vs 12.3%, respectively; P<.001), although preexposure prophylaxis prescriptions were equivalent (P=1.0). Among the subgroup of patients who were counseled about preexposure prophylaxis, 18.5% of patients in the active control arm and 3.4% in the preexposure prophylaxis registered nurse arm were prescribed preexposure prophylaxis (P=.02). Concerning maintenance, clinical decision support tools alone resulted in preexposure prophylaxis counseling of 1.0% of patients during the maintenance phase vs 0.6% of patients during the baseline phase and 11.2% of patients during the clinical trial phase (P<.001). Preexposure prophylaxis prescriptions were not statistically different among the 3 phases (P=.096). CONCLUSION: A preexposure prophylaxis nurse effectively increased HIV prevention discussions but did not lead to more preexposure prophylaxis prescriptions than the preexposure prophylaxis-focused clinical decision support tools used by providers. The decrease in preexposure prophylaxis counseling after the trial phase suggests that persistent interventions are needed to maintain effects.

RESUMEN

BACKGROUND: Mycoplasma genitalium (MG) is a prevalent sexually transmitted infection, but little is known about the associated inflammatory signatures in the genital tract of adolescents and young adult women. METHODS: Adolescents and young adult women aged 13 to 24 years were recruited. Demographic information, sexual behavior history, and medical history were collected. Vaginal swab samples were tested for MG, Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, bacterial vaginosis, and measurement of 13 cytokines, chemokines, and antimicrobial proteins. Vaginal cytokine concentrations were compared by MG infection status. The strength of associations between multiple factors and MG infection was evaluated. RESULTS: Of 215 participants, 16.7% (95% confidence interval [CI], 12.0%-22.4%) had MG infection. Inflammation was not associated with MG infection (P > 0.05). M. genitalium infection was associated with C. trachomatis infection (adjusted prevalence ratio [aPrR], 3.02; 95% CI, 1.69-5.39), bisexual behavior in the past 3 months (aPrR, 2.07; 95% CI, 1.18-3.64), genitourinary symptoms (aPrR, 2.06; 95% CI, 1.22-3.49), and self-reported Black race (aPrR, 3.53; 95% CI, 1.11-11.18). CONCLUSIONS: Higher levels of genital tract cytokines were not associated with MG infection. C. trachomatis infection, bisexual behavior, self-reported Black race, and genitourinary symptoms were associated with an increased likelihood of MG infection.

RESUMEN

AIMS: To assess the pelvic floor function in cervical cancer patients after radical hysterectomy and its relationship with urinary incontinence (UI). METHODS: Cervical cancer patients who underwent radical hysterectomy were recruited from 18 hospitals in China from January 2012 to March 2015. Pelvic floor examinations were conducted by measuring the pelvic floor muscle strength, fatigue of pelvic floor muscle fatigue, dynamic pressure of vaginal, nerve injury, A3 feedback, muscle potential, static tension, and dynamic tension. Postoperative urinary incontinence (UI) was identified using the International Consultation on Incontinence Questionnaire. Multivariable logistic regression analysis was used to assess the association of pelvic floor function examination results with postoperative UI. RESULTS: Totally 169 patients were included in this study. The prevalence of UI was 39.6% (67/169). The proportion of abnormal fatigue of Type I muscle (64% vs. 36%, p = .04) and abnormal A3 feedback (53.9% vs. 46.1%, p = .03) were higher among patients with postoperative UI compared to those without UI. In the multivariable analysis, abnormal fatigue of Type I muscle (odds ratio [OR] = 3.73, 95% confidence interval [CI]: 1.42-9.84), abnormal A3 feedback (OR = 2.40, 95% CI: 1.04-5.51), and length of resected vagina > 3 cm (OR = 3.44, 95% CI: 1.27-9.31) were associated with postoperative UI. Compared to laparoscopy, laparotomy was less likely to cause postoperative UI (OR = 0.12, 95% CI:0.04-0.33). CONCLUSIONS: The abnormal function of the pelvic floor muscle is related to postoperative UI. Early assessment among these patients is needed to prevent the development of pelvic floor disorder postoperatively.

RESUMEN

Drug relapse among addicts often occurs due to the learned association between drug-paired cues and the rewarding effects of these drugs, such as morphine. Contextual memory associated with morphine has a central role in maintenance and relapse. We showed that morphine-conditioned place preference (CPP) activates extracellular-regulated protein kinase (ERK) in the nucleus accumbens (NAc). The main enzymes that mediate ERK dephosphorylation are members of the dual-specificity phosphatase (DUSP) superfamily. It is unclear which members regulate the morphine CPP-induced activation of ERK. After screening, DUSP15 was found to be decreased during both morphine CPP expression and the reinstatement period. Intra-NAc infusions of AAV-DUSP15 (overexpression) not only prevented the expression of morphine-induced CPP but also facilitated extinction, inhibited reinstatement, and abolished ERK activation. However, after repeated morphine exposure and withdrawal in mice, there was no change in the expression of p-ERK and DUSP15, and the overexpression of DUSP15 in the NAc did not improve the impaired spatial memory or anxiety-like behaviour induced by morphine. Together, these findings indicate that DUSP15 not only prevents the expression of drug-paired contextual memory but also promotes the extinction of existing addiction memories, thus providing a novel therapeutic target for the treatment of drug addiction.

RESUMEN

Montmorillonite (Mt) is a kind of 2:1 type layered phyllosilicate mineral with nanoscale structure, large surface area, high cation exchange capacity and excellent adsorption capacity. By virtue of such unique properties, many scholars have paid much attention to the further modification of Mt-based two-dimensional (2D) functional composite materials, such as Mt-metal hydroxides and Mt-carbon composites. In this review, we focus on two typical Mt-2D nanocomposite: Mt@layered double hydroxide (Mt@LDH) and Mt@graphene (Mt@GR) and their fabrication strategies, as well as their important applications in pollution adsorption, medical antibacterial, film thermal conduction and flame-retardant. In principle, the prospective trend of the composite preparation of Mt-2D nancomposites and promising fields are well addressed.

RESUMEN

INTRODUCTION AND HYPOTHESIS: To investigate the relationship between race and anal incontinence (AI). Our hypotheses were (a) AI symptoms are similar between white and black women and (b) asymptomatic black and white women are equally likely to develop AI over one year of prospective observation. METHODS: Parous women enrolled in a longitudinal cohort study were assessed for AI symptoms annually using Epidemiology of Prolapse and Incontinence Questionnaire. An AI score > 0 indicated any bother from AI; a score > 22.8 indicated clinically significant AI. We compared the odds of AI scores >0 at the visit level between white vs black women with logistic regression models using generalized estimating equations. We also estimated the odds of new AI symptoms at time T + 1(one year later) among women free of AI symptoms at time T comparing white vs black women. In the latter analysis, we considered new AI symptoms to be represented by scores above 11.4. Covariates included in the adjusted models were: mode of delivery, obstetrical anal sphincter injuries, body mass index, age at the first delivery, and parity at enrollment. RESULTS: Among 1256 participants, 189 (15.0%) were black. AI score = 0 was observed at 74.2% (= 5122/6902) person-visits. The adjusted odds ratio of AI score > 0 was 1.83 (95% CI 1.24, 2.70) for white vs black women. Across 4364 visit pairs with AI score = 0 at time T, 203 (4.7%) had AI score > 11.4 at visit T + 1 and white race significantly increased the odds of developing symptoms at time T + 1 (adjusted OR = 2.26, 95% CI 1.28, 3.98). CONCLUSIONS: In an analysis that controlled for mode of delivery, obstetrical anal sphincter injuries, obesity, age at first delivery, and parity, white race was significantly associated with AI symptoms at any point in time as well as to the development of AI over one year of observation.

RESUMEN

AIMS: Ethanol is a small molecule capable of interacting with numerous targets in the brain, the mechanisms of which are complex and still poorly understood. Studies have revealed that ethanol-induced hippocampal neuronal injury is associated with oxidative stress. Grape seed procyanidin (GSP) is a new type of antioxidant that is believed to scavenge free radicals and be anti-inflammatory. This study evaluated the ability and mechanism by which the GSP improves ethanol-induced hippocampal neuronal injury. METHODS: Primary cultures of hippocampal neurons were exposed to ethanol (11, 33 and 66 mM, 1, 4, 8, 12 and 24 h) and the neuroprotective effects of GSP were assessed by evaluating the activity of superoxide dismutase (SOD), the levels of malondialdehyde (MDA) and lactate dehydrogenase (LDH) and cell morphology. RESULTS: Our results indicated that GSP prevented ethanol-induced neuronal injury by reducing the levels of MDA and LDH, while increasing the activity of SOD. In addition, GSP increased the number of primary dendrites and total dendritic length per cell. CONCLUSION: Together with previous findings, these results lend further support to the significance of developing GSP as a therapeutic tool for use in the treatment of alcohol use disorders.

RESUMEN

In the study of indoor simultaneous localization and mapping (SLAM) problems using a stereo camera, two types of primary features-point and line segments-have been widely used to calculate the pose of the camera. However, many feature-based SLAM systems are not robust when the camera moves sharply or turns too quickly. In this paper, an improved indoor visual SLAM method to better utilize the advantages of point and line segment features and achieve robust results in difficult environments is proposed. First, point and line segment features are automatically extracted and matched to build two kinds of projection models. Subsequently, for the optimization problem of line segment features, we add minimization of angle observation in addition to the traditional re-projection error of endpoints. Finally, our model of motion estimation, which is adaptive to the motion state of the camera, is applied to build a new combinational Hessian matrix and gradient vector for iterated pose estimation. Furthermore, our proposal has been tested on EuRoC MAV datasets and sequence images captured with our stereo camera. The experimental results demonstrate the effectiveness of our improved point-line feature based visual SLAM method in improving localization accuracy when the camera moves with rapid rotation or violent fluctuation.

RESUMEN

LPIN2 is one of the members of the Lipin family, which acts as a phosphatidate phosphatase enzyme. In this study, we identified the cDNA sequence and exonic variants of chicken LPIN2, and evaluated its spatio-temporal expression patterns. It indicated that chicken LPIN2 cDNA contained a 2,664-bp open reading frame flanked by a 176-bp 5' untranslated region and a 429-bp 3' untranslated region, predicted encoding one protein of 886 amino acids. Fourteen variants (three missense mutations) were detected from the coding region of chicken LPIN2. W265L was predicted to affect the gene function (p < 0.01) and eight synonymous mutations were predicted to affect the binding sites of SR proteins, which suggested the important functions of these variants. Real-time quantitative PCR revealed that LPIN2 in two genotypic chickens (LD and HB chickens, with difference in growth rate) presented similar tissue expression patterns, which was liver and ovary enriched with low abundance in skeleton muscles. Chicken LPIN2 exhibited tissue-specific temporal-expression patterns during postnatal development (0-16 weeks). Chicken cutaneous LPIN2 was in steady-state mRNA levels during postnatal development; chicken LPIN2 mRNA in pectoralis major had a prominent level at 0 week-old, then dropped dramatically at 4 week-old and maintained a relatively low level through 4-16 weeks; while chicken hepatic LPIN2 had a relatively high expression at 0 week-old, with a relatively low level through 4-12 weeks and a slight increase at 16 week-old. The studies about the basic gene features of chicken LPIN2 would lay the foundation for further exploring its biological function.

RESUMEN

The egg parasitoid Mesocomys trabalae Yao, Yang, and Zhao is used as a biocontrol agent against the emerging defoliator pest Caligula japonica Moore in East Asia. It has been proven that the eggs of Antheraea pernyi Guérin-Méneville can be used as a factitious host for the mass production of M. trabalae. We examined the parasitic behavior and morphological characteristics of the developmental stages of M. trabalae reared on A. pernyi eggs. The parasitic behavior of M. trabalae encompasses 10 steps, involving searching, antennation, locating the oviposition site, drilling, probing, detecting, oviposition, host feeding, grooming, and resting, with the oviposition step further divided into 3 stages. We determined that the parasitoid released an egg during the second stage of the oviposition step, while her body remained in a relatively static state. Among all the steps in parasitic behavior, probing occupied the longest time, accounting for 26.33% of the entire parasitism process. It was followed by oviposition (15.88%), drilling (15.10%), antennation (13.09%), detecting (10.79%), host feeding (10.02%), and the remaining steps, each occupying less than 5.00% of the total time in steps. The pre-emergence of adult M. trabalae comprised of 4 stages: egg (0-1 day), larva (2-6 days), prepupa (7-11 days), pupa (12-20 days), followed by the development into an adult, and it usually took 20-22 days to develop from an egg into an adult at 25°C. This study advances our understanding of the biology of Mesocomys parasitoids and their mass-rearing for use in augmentation programs.

RESUMEN

Background: Nephritis is a pivotal catalyst in chronic kidney disease (CKD) progression. Although epidemiological studies have explored the impact of plasma circulating metabolites and drugs on nephritis, few have harnessed genetic methodologies to establish causal relationships. Methods: Through Mendelian randomization (MR) in two substantial cohorts, spanning large sample sizes, we evaluated over 100 plasma circulating metabolites and 263 drugs to discern their causal effects on nephritis risk. The primary analytical tool was the inverse variance weighted (IVW) analysis. Our bioinformatic scrutiny of GSE115857 (IgA nephropathy, 86 samples) and GSE72326 (lupus nephritis, 238 samples) unveiled anomalies in lipid metabolism and immunological characteristics in nephritis. Thorough sensitivity analyses (MR-Egger, MR-PRESSO, leave-one-out analysis) were undertaken to verify the instrumental variables' (IVs) assumptions. Results: Unique lipoprotein-related molecules established causal links with diverse nephritis subtypes. Notably, docosahexaenoic acid (DHA) emerged as a protective factor for acute tubulointerstitial nephritis (ATIN) (OR1 = 0.84, [95% CI 0.78-0.90], p1 = 0.013; OR2 = 0.89, [95% CI 0.82-0.97], p2 = 0.007). Conversely, multivitamin supplementation minus minerals notably increased the risk of ATIN (OR = 31.25, [95% CI 9.23-105.85], p = 0.004). Reduced α-linolenic acid (ALA) levels due to lipid-lowering drugs were linked to both ATIN (OR = 4.88, [95% CI 3.52-6.77], p < 0.001) and tubulointerstitial nephritis (TIN) (OR = 7.52, [95% CI 2.78-20.30], p = 0.042). While the non-renal drug indivina showed promise for TIN treatment, the use of digoxin, hydroxocobalamin, and liothyronine elevated the risk of chronic tubulointerstitial nephritis (CTIN). Transcriptome analysis affirmed that anomalous lipid metabolism and immune infiltration are characteristic of IgA nephropathy and lupus nephritis. The robustness of these causal links was reinforced by sensitivity analyses and leave-one-out tests, indicating no signs of pleiotropy. Conclusion: Dyslipidemia significantly contributes to nephritis development. Strategies aimed at reducing plasma low-density lipoprotein levels or ALA supplementation may enhance the efficacy of existing lipid-lowering drug regimens for nephritis treatment. Renal functional status should also be judiciously considered with regard to the use of nonrenal medications.

RESUMEN

Puerarin is an isoflavone extracted from Gegen (Pueraria lobata) and has been widely utilized to treat various human diseases; however, information regarding its benefits in animal production is limited. In this study, we aimed to investigate the influence of dietary puerarin supplementation on growth performance, immune organ index, immunoglobulin profile, antioxidant capacity, and intestinal morphology in pigeons. In total, 375 healthy 28-day-old White King pigeons were randomly divided into five groups, each consisting of five replicates and 15 pigeons per replicate. Each group was administered one of five dietary treatments: the basal diet, or the basal diet supplemented with 40, 80, 120, or 160 mg/kg puerarin. Treatment duration was 30 days following a 7-day acclimation period. Puerarin treatment did not significantly alter the growth performance of pigeons but afforded a significant linear enhancement in the thymus index (P < 0.05). Additionally, puerarin supplementation significantly increased serum immunoglobulin A and immunoglobulin M levels in pigeons in a linear manner (P < 0.05). Similarly, puerarin significantly and linearly increased the activities of total antioxidant capacity, superoxide dismutase, glutathione, and catalase in the serum and liver, and decreased the malondialdehyde content (P < 0.05). Moreover, the villus height (VH), crypt depth (CD), and VH/CD ratio of the small intestine (including the duodenum, jejunum, and ileum) increased linearly upon puerarin supplementation (P < 0.05). Collectively, these results indicate that puerarin supplementation could improve the immune response, antioxidant capacity, and intestinal morphology of pigeons.

RESUMEN

Importance: Postpartum human papillomavirus (HPV) vaccination is a promising strategy to increase HPV vaccination uptake in the US, particularly for reaching vaccine-naive women and those who lack health insurance beyond the pregnancy period. However, completion of the 3-dose vaccine regimen is challenging. Objective: To evaluate the immunogenicity of a 2-dose postpartum HPV vaccination regimen (0 and 6 months) and assess whether it is noninferior to a 3-dose postpartum HPV vaccination regimen (0, 1-2, and 6 months) administered to historical controls. Design, Setting, and Participants: A noninferiority, open-label, nonrandomized immunogenicity trial was conducted from August 4, 2020, to June 23, 2022, of postpartum patients aged 15 to 45 years who delivered at 2 hospitals in Baltimore, Maryland. Historical controls were adolescents and young women aged 16 to 26 years. Intervention: Two doses of the nonavalent HPV vaccine administered 6 months apart. Main Outcomes and Measures: The primary outcome was noninferiority (90% CI, lower bound >0.67) of the geometric mean titer (GMT) ratio for HPV-16 among postpartum women compared with historical controls. Secondary outcomes were noninferiority of GMT ratios for the other 8 HPV types and percentage seroconversion for each HPV type. As a noninferiority trial, the primary analysis used the per-protocol analysis. Results: Of 225 enrolled participants, the mean (SD) age at baseline was 29.9 (6.8) years, and 171 (76.0%) were HPV-16 seronegative at baseline. Of these 171 participants, 129 (75.4%) received a second vaccine dose and completed the subsequent 4-week serologic measurements. Relative to historical controls, the HPV-16 GMT ratio was 2.29 (90% CI, 2.03-2.58). At month 7, HPV-16 GMT was higher after the 2-dose regimen (7213.1 mMU/mL [90% CI, 6245.0-8331.4 mMU/mL]) than among historic controls after the 3-dose regimen (3154.0 mMU/mL [90% CI, 2860.2-3478.0 mMU/mL]). Similarly, the lower bound of the 90% CI of the GMT ratio was above 1 for the 8 HPV types 6, 11, 18, 31, 33, 45, 52, and 58. A total of 118 of 134 women (88.1%) seroconverted for HPV-16 after the first dose; 4 weeks after the second dose, the seroconversion rate was 99% or greater for all HPV types. Conclusions and Relevance: This study suggests that immunogenicity of a 2-dose HPV vaccination regimen given 6 months apart among postpartum women was noninferior to a 3-dose regimen among young historical controls. Most women seroconverted after the first dose of the 2-dose regimen. These results demonstrate that postpartum vaccination using a reduced schedule may be a promising strategy to increase HPV vaccine series completion. Trial Registration: ClinicalTrials.gov Identifier: NCT04274153.

RESUMEN

Aim: To develop novel prognostic markers for early detection and prognosis of ovarian cancer (OC). Materials & methods: We utilized bioinformatics analysis to identify and construct a prognostic model consisting of lncRNAs centered around JARID2 and explored the potential ceRNA network in OC. Cell functional experiments were conducted to validate the reliability of the ceRNA network and investigate the functional role of JARID2 in OC. Results: We constructed a nomogram composed of ten lncRNAs and identified the PKD1P6/miR-424-5p/JARID2 axis. Furthermore, our findings indicated that JARID2 promotes the proliferation of SKOV3 cells, suggesting its oncogenic role in OC. Conclusion: JARID2, potentially regulated by the PKD1P6/miR-424-5p/JARID2 axis, represents a potential novel biomarker for OC.


In this study, we aimed to find new markers that can help detect and diagnose ovarian cancer (OC) at an early stage. To achieve this, we used advanced computer analysis to identify a specific gene called JARID2 and its associated lncRNAs. We also explored how these molecules interact with each other in OC cells. Through our experiments, we developed a model called a nomogram that includes ten lncRNAs. We discovered a specific pathway involving the PKD1P6 gene, a molecule called miR-424-5p and the JARID2 gene. This pathway appears to play a role in promoting the growth of OC cells. Based on our findings, JARID2, possibly regulated by the PKD1P6/miR-424-5p/JARID2 pathway, shows promise as a new biomarker for OC. This research may contribute to early detection and prognosis of the disease.

RESUMEN

OBJECTIVE: To explore the association of neighborhood-level socioeconomic status (SES) and race with developing pelvic inflammatory disease (PID) after sexually transmitted infection (STI) among female adolescents and young adults in Maryland. METHODS: We used Maryland statewide hospital claims data (outpatient and inpatient visits) for this retrospective cohort study. Female adolescents and young adults aged 15-24 years who had at least one STI from July 1, 2013, to March 31, 2015, were included. A participant entered the cohort on the date of the first STI diagnosis and was followed up until PID occurrence or 3 years after the first STI. Median household income of the participant's residential ZIP code tabulation area was used as the neighborhood-level SES. Discrete-time hazard models were used to estimate the hazard of PID. RESULTS: Of the 2,873 participants, 88.5% were of Black race, and 67.2% were aged 20-24 years. The hazard of PID after an STI among Black women was 1.40 times that of White women (95% CI 1.06-1.85). After adjustment for age, insurance type, and number of STI events, the hazard ratio (HR) did not change. However, adding neighborhood-level SES to the model attenuated the disparity in PID after STI between Black and White women (HR 1.25, 95% CI 0.94-1.67). CONCLUSION: Racial disparities in PID diagnosis are mitigated by neighborhood-level SES.

RESUMEN

3-Hydroxymethylglutaryl-CoA synthase 2 (HMGCS2) is the rate-limiting enzyme for ketone body synthesis, and most current studies focus on mitochondrial maturation and metabolic reprogramming. The role of HMGCS2 was evaluated in a pan-cancer multi-database using R language, and HMGCS2 was lowly expressed or not differentially expressed in all tumor tissues compared with normal tissues. Correlation analysis of clinical case characteristics, genomic heterogeneity, tumor stemness, and overall survival revealed that HMGCS2 is closely related to clear cell renal cell carcinoma (KIRC). Single-cell sequencing data from normal human kidneys revealed that HMGCS2 is specifically expressed in proximal tubular cells of normal adults. In addition, HMGCS2 is associated with tumor immune infiltration and microenvironment, and KIRC patients with low expression of HMGCS2 have worse prognosis. Finally, the results of cell counting kit 8 assays, colony formation assays, flow cytometry, and Western blot analysis suggested that upregulation of HMGCS2 increased the expression of key tumor suppressor proteins, inhibited the proliferation of clear cell renal cell carcinoma cells and promoted cell apoptosis. In conclusion, HMGCS2 is abnormally expressed in pan-cancer, may play an important role in anti-tumor immunity, and is expected to be a potential tumor prognostic marker, especially in clear cell renal cell carcinoma.

RESUMEN

Parasitic wasps are abundant and diverse Hymenoptera insects that lay their eggs inside or on the external surface of the host and inject venom into the host to create a more favorable environment for the larvae to survive and regulate the host's immunity, metabolism, and development. But research on the composition of egg parasitoid venom is very limited. In this study, we used a combination of transcriptomic and proteomic approaches to identify the protein fractions of the venom in both eupelmid egg parasitoids, Anastatus japonicus and Mesocomys trabalae. We identified 3422 up-regulated venom gland genes (UVGs) in M. trabalae and 3709 in A. japonicus and analyzed their functions comparatively. By proteome sequencing, we identified 956 potential venom proteins in the venom pouch of M. trabalae, of which 186 were contained in UVGs simultaneously. A total of 766 proteins were detected in the venom of A. japonicus, of which 128 venom proteins were highly expressed in the venom glands. At the same time, the functional analysis of these identified venom proteins was carried out separately. We found the venom proteins in M. trabalae are well known but not in A. japonicus, which may be related to the host range. In conclusion, identifying venom proteins in both egg parasitoid species provides a database for studying the function of egg parasitoid venom and its parasitic mechanism.

RESUMEN

PURPOSE: Youth face barriers to sexual and reproductive health (SRH). Few states require the delivery of comprehensive sex education in schools, and youth report challenges with accessing clinical care. We sought to identify youth's perceived barriers and facilitators to SRH in their communities. METHODS: We utilized photovoice, a community-based participatory research methodology. Youth were recruited from high schools in Baltimore, Maryland. Participants were given a tutorial on Photovoice methodology and photography. In groups of 5-7 participants, youth brainstormed questions relevant to their perspective of SRH. Three months were allocated to taking photographs. Participants wrote brief narratives to accompany their photographs, and group level assessment was used for participants to comment on others' photographs. Participants discussed the narratives and comments, created themes, and generated action steps to address barriers to SRH. Further thematic analysis was conducted using NVivo. RESULTS: There were 30 participants aged 14-19 years with 26 self-identifying as female and four nonbinary. Self-identified race/ethnicity included 50% Black/African American, 30% Asian American, and 20% White or Hispanic/Latino. Four domains emerged: desire for societal-level change, community-level change, peer-level change, and positive examples of SRH within their communities (e.g., gender-inclusive spaces and free menstrual products). DISCUSSION: Youth photographs shed light on a strong desire for an improved school environment, in terms of safety, cleanliness, gender-inclusivity, menstrual product access, and SRH education.

RESUMEN

PURPOSE: The COVID-19 pandemic highlighted the need for innovative approaches to delivering care. Self-collect, mail-in sexually transmitted infection (STI) testing could address barriers to in-person STI testing, particularly for youth, who bear a disproportionate burden of STIs. This study sought to obtain youth input on the development of a free self-collect, mail-in STI testing program. METHODS: Focus group discussions (n = 5, 45-60 minutes each) were conducted with 28 youth ages 14-19 years old living in Baltimore, Maryland. Focus group discussions were based on a conceptual framework of patient-centered health-care access, and a prototype online program was discussed. Transcribed data were coded thematically. Memos were written to synthesize findings and identify representative quotes. RESULTS: Participants noted existing barriers to in-person STI testing barriers including individual-level (e.g., lack of knowledge), interpersonal-level (e.g., stigma), and structural-level (e.g., financial). Although participants expressed concerns about self-collect, mail-in STI testing (e.g., accuracy of self-swabbing), there was overall acceptance of the program, and many felt it would address current barriers to testing. Opportunities to improve the testing program included all four steps of testing process: kit ordering, receipt of the kit and swabbing, post-testing experience, and communication of results and treatment. Specifically, participants desired expanded shipping options to schools, and mail drop-off points such as lockers and local convenience stores; more transparency about testing and treatment; and hearing directly from health-care providers to assuage any concerns. DISCUSSION: Self-collect, mail-in STI testing was favorable among youth, and could be a viable option for increasing youth access to STI testing.

RESUMEN

Binge alcohol drinking during adolescence has long-term effects on the adult brain that alter brain structure and behaviors, but the underlying mechanisms remain poorly understood. Extracellular signal-regulated kinase (ERK) is involved in the synaptic plasticity and pathological brain injury by regulating the expression of cyclic adenosine monophosphate response element binding protein (CREB) and brain-derived neurotrophic factor (BDNF). Dual-specificity phosphatase 6 (DUSP6) is a critical effector that dephosphorylates ERK1/2 to control the basal tone, amplitude, and duration of ERK signaling. To explore DUSP6 as a regulator of ERK signaling in the mPFC and its impact on long-term effects of alcohol, a male mouse model of adolescent intermittent alcohol (AIA) exposure was established. Behavioral experiments showed that AIA did not affect anxiety-like behavior or sociability in adulthood, but significantly damaged new object recognition and social recognition memory. Molecular studies further found that AIA reduced the levels of pERK-pCREB-BDNF-PSD95/NR2A involved in synaptic plasticity, while DUSP6 was significantly increased. Intra-mPFC infusion of AAV-DUSP6-shRNA restored the dendritic spine density and postsynaptic density thickness by reversing the level of p-ERK and its downstream molecular expression, and ultimately repaired adult cognitive impairment caused by chronic alcohol exposure during adolescence. These findings indicate that AIA exposure inhibits ERK-CREB-BDNF-PSD95/NR2A by increasing DUSP6 in the mPFC in adulthood that may be associated with long-lasting cognitive deficits.
