We conclude that exogenous cfDNA activates a defensive response in human spermatozoa associated with the nuclease-mediated induction of DNA fragmentation, possibly involving the participation of TLR9 and CD4. These novel insights have significant implications for our understanding of DNA fragmentation in the male germ line and open up new pathways for the remediation of this condition.
More and more U.S. states are legalizing marijuana use for both recreational and medical purposes. This study estimated the prevalence of current marijuana use and identified its individual-level predictors among adult cancer survivors (CS) living in 15 U.S. states and territories.

U.S. nationally representative, cross-sectional data from the 2018 Behavioral Risk Factor Surveillance System Survey (BRFSS) Marijuana Use module were used. A total of 9325 CS was included. Analyses were weighted to account for BRFSS's complex survey design with results generalizable to 4.02 million CS. The outcome was current (past 30-day) marijuana use. Weighted prevalence estimates were computed. Multivariable logistic regression examined individual-level demographic, socio-economic, clinical, and behavioral predictors associated with marijuana use.

Weighted analysis indicated that 9.2% reported current marijuana use, 50.5% of which used it for medical reasons with smoking being the main method of administration, 71.3%. Among racial/ethnic groups, non-Hispanic blacks had the highest prevalence of marijuana use (18.6%). The prevalence of current marijuana use decreased with age (P<.001). CS were more likely to use marijuana if they were male, non-Hispanic black (versus non-Hispanic whites), not married, uninsured, current and former tobacco smoker, binge drinker, ever having depressive disorder, and those who had fair/poor health.

Marijuana use is prevalent among CS and certain subgroups are at higher risk for marijuana use. With the proliferation of marijuana legalization, identifying high-risk CS for marijuana use and informing them about its risks and safety is critical.

Initial evidence has suggested that worry, defined as excessive, unrealistic thoughts focused on the possibility of future negative events, may contribute to e-cigarette use behavior. Yet, how these established relations differ across groups, such as male and female e-cigarette users, has not been explored. The present study evaluated the effect of worry on perceived barriers for quitting e-cigarettes, perceptions of benefits for e-cigarette use, and perceived negative consequences of e-cigarette use across sex. The sample included 584 current e-cigarette users (52.2% female, Mage = 35.15 years, SD = 10.27). Analyses indicated a significant interaction between sex and worry on each criterion variable (perceived benefits b = 0.02, SE = 0.01, t = -2.73, p = .01; perceived barriers for quitting e-cigarettes b = -0.45, SE = 0.08, t = -5.70, p ≤ 0.001; negative consequences to use b = -0.033, SE = 0.01, t = -4.50, p less then .001), such that worry was more strongly related to each outcome among males than females. These findings suggest that sex plays a role in e-cigarette use behaviors and that males may constitute a group that is especially vulnerable to the effects of worry on both positive and negative e-cigarette use perceptions and perceived barriers for quitting e-cigarettes.
To test the preliminary impact and participant experience/satisfaction of Invite Only VR A Vaping Prevention Game (Invite Only VR), an electronic cigarette (e-cigarette) prevention game prototype using virtual reality (VR) hardware.

Forty-seven adolescents (38 boys; mean age=14.23years, SD=0.914) were enrolled to test the preliminary impact of Invite Only VR on knowledge, perceived likelihood of using e-cigarettes, perceptions of harm, attitudes, social norms, and self-efficacy to refuse e-cigarettes using a pre/post design. Experience/satisfaction was measured following gameplay. Paired-samples t-tests and associated effect sizes were used to assess changes in the dependent variables. ALLN clinical trial Descriptive statistics were used to report on gameplay experience/satisfaction.

From pre- to post-gameplay, players significantly increased in knowledge (t(34)=-5.594, p<.001, Cohen's d=0.946) and perceptions of e-cigarette harm (t(34)=-3.370, p=.002, Cohen's d=0.530) and decreased their perceived likelihood of using e-cigarettes in the future (t(35)=2.140, p=.039, Cohen's d=1.274). No significant change was found for attitudes towards e-cigarettes, social norm perceptions, nor refusal self-efficacy. Participants reported that they enjoyed playing the game (M=3.00, SD=0.99) and that they would tell their friends to play (M=3.08, SD=0.91).

Invite Only VR may help players develop knowledge and correct harm perceptions regarding e-cigarettes while reducing their perceived likelihood of using them in the future. Participant enjoyment also provides an initial indication that the intervention may be acceptable for use with adolescents.

We followed 462 individuals with HIV infection and measured their NK, CD4+ T, CD8+ T cell counts and viral loads. Our data showed that individuals with high NK cell counts had much lower viral loads and higher CD4+ T cell counts. NK cell counts during primary infection were negatively correlated with viral set-point and viral loads at one-year-infection point, and positively correlated with CD4+ T cell counts at one-year-infection and one-year-ART point. Moreover, the NK cell counts during primary infection can predict HIV disease progression and immune restoration after ART. In conclusion, NK cell counts during primary infection represents a potential predictive biomarker to predict HIV disease prognosis in the clinic.
The Epworth sleepiness scale (ESS) is often used to evaluate the impact of treatment in patients with obstructive sleep apnea hypopnea syndrome (OSA). We aimed to evaluate the correlation between ESS and the Maintenance of Wakefulness Test (MWT) in a population of OSA patients treated with positive airway pressure (PAP).

We retrospectively included all patients during a 2-year period who were diagnosed with OSA in our sleep clinic and required PAP therapy. ESS was evaluated at baseline and after PAP therapy for all patients, and all had a concomitant MWT. Correlation between final ESS, change in ESS, and MWT were evaluated using Spearman's correlation. Given that MWT is considered as the gold standard, the diagnostic performance of ESS was evaluated against MWT.

Hundred thirty-four OSA patients were included. At the time of MWT, 89.6% of the patients were compliant (PAP use ≥4hours/night), and only 9 (6.7%) had persistent sleepiness despite PAP treatment (mean sleep latency at MWT<19.4min). Moderate correlation was observed between final ESS and MWT (Spearman's correlation coefficient=-0.42), but no correlation was found between change in ESS and MWT. Diagnostic performance was as follows for final ESS sensitivity=55.6%, specificity=84.8%, PPV=20.8%, and NPV=96.4%.

ESS was moderately correlated with MWT in a population of OSA patients compliant with PAP therapy. In this population, ESS showed poor diagnostic performance in identifying patients with persistent excessive daytime sleepiness. CLINICALTRIALS.

NCT03629834.Infection with the virus, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) stimulates an immune response which can serve as a marker for current or past exposure to this pathogen, and possibly for resistance to re-infection. This response to COVID-19 can be monitored based on the production of antibodies, and thus, serologic tests have become available for diagnostic purposes. Despite progress in this area, concerns have been raised that too many of the commercially available serologic detection systems are not completely reliable. To address this issue, Western blots should be considered for confirming a positive or borderline-positive result from a screening test, such as an ELISA. An additional benefit of Western blots would be to identify antigens that could form the basis for developing a vaccine. Little is known about the cell-mediated immune response against COVID-19. One way to address this would be to use skin testing to measure the delayed-type hypersensitivity response in patients recovering from COVID-19.
The (pro)renin receptor (ATP6AP2) is cleaved and released as soluble ATP6AP2 (sATP6AP2). The sATP6AP2 is detected in plasma and urine and is elevated in women with gestational diabetes and preeclampsia. The source and cleavage pathway of sATP6AP2 in pregnancy is unknown. The syncytiotrophoblast is the major placental secretory layer and is in direct contact with maternal blood. Both FURIN and Site 1 protease (MBTPS1) cleave sATP6AP2 in non-placental cells. We postulated that ATP6AP2 was cleaved by FURIN and/or MBTPS1 and that sATP6AP2 is secreted by the placental syncytiotrophoblast.

Term primary trophoblast cells were transfected with FURIN siRNA, negative control siRNA or vehicle. In a separate experiment, primary trophoblasts were treated with a pro-protein convertase inhibitor (DEC-RVKR-CMK), an MBTPS1 inhibitor (PF 429242) or vehicle. Trophoblasts were left to spontaneously syncytialise before cells and supernatants were collected and intracellular and extracellular sATP6AP2 levels analysed by immuno had no effect. Hence, a convertase other than FURIN or MBTPS1 is most likely responsible for placental sATP6AP2 secretion.
Risk factors are biological or environmental characteristics increasing the likelihood of delays in child development. Meanwhile, protective factors are conditions that can minimize risks and favor the acquisition of skills. Infants with risk indicators for hearing loss (RIHL) tend to live in less stimulating environments which may lead to lower cognitive, language, and motor development.

To compare the cognitive, language, and motor development of infants under the influence of risk and protective factors.

A cross-sectional observational study in which 259 infants aged 8-10 months were assessed for cognitive, language, and motor development using the Bayley Scales of Infant and Toddler Development - Third Edition (BSITD-III). The groups were formed according to the presence or absence of RIHL and the quality of the resources, being SG-AE (Study Group with Adequate Environment), SG-IE (Study Group with Inadequate Environment), CG-AE (Compared Group with Adequate Environment)) and CG-IE (Compared Group with Inadequate Environment).
