Age matters: Microbiome depletion prior to repeat mild traumatic brain injury differentially alters microbial composition and function in adolescent and adult rats

Dysregulation of the gut microbiome has been shown to perpetuate neuroinflammation, alter intestinal permeability, and modify repetitive mild traumatic brain injury (RmTBI)-induced deficits. However, there have been no investigations regarding the comparative effects that the microbiome may have on RmTBI in adolescents and adults. Therefore, we examined the influence of microbiome depletion prior to RmTBI on microbial composition and metabolome, in adolescent and adult Sprague Dawley rats. Rats were randomly assigned to standard or antibiotic drinking water for 14 days, and to subsequent sham or RmTBIs. The gut microbiome composition and metabolome were analysed at baseline, 1 day after the first mTBI, and at euthanasia (11 days following the third mTBI). At euthanasia, intestinal samples were also collected to quantify tight junction protein (TJP1 and occludin) expression. Adolescents were significantly more susceptible to microbiome depletion via antibiotic administration which increased pro-inflammatory composition and metabolites. Furthermore, RmTBI induced a transient increase in ‘beneficial bacteria’ (Lachnospiraceae and Faecalibaculum) in only adolescents that may indicate compensatory action in response to the injury. Finally, microbiome depletion prior to RmTBI generated a microbiome composition and metabolome that exemplified a potentially chronic pathogenic and inflammatory state as demonstrated by increased Clostridium innocuum and Erysipelatoclostridium and reductions in Bacteroides and Clostridium Sensu Stricto. Results highlight that adolescents are more vulnerable to RmTBI compared to adults and dysbiosis prior to injury may exacerbate secondary inflammatory cascades.
Influence of COVID-19 infection on placental function.

OBJECTIVES Pregnant women are more susceptible to infectious diseases because of their natural immunosuppression. SARS-CoV-2 seems to be a potential risk for the condition of women and the fetus. Unfortunately, knowledge of the influence of coronavirus disease 19 (COVID-19) on pregnant women and their children is still very limited, and further investigation and analysis are needed. The aim of the study was to conduct a meta-analysis of research about the impact of COVID-19 on the placenta. MATERIAL AND METHODS Articles published between 2020 and 2021 and contained in the PubMed and Elsevier databases were analyzed. RESULTS The SARS-CoV-2 infection also led to pregnancy complications in the patients. The most common pregnancy complications include caesarean delivery (80%), preterm delivery (26%), fetal distress (8%), premature rupture of the membranes (9%) and stillbirth (2%). Among the observed patients, neonatal complications occurred, such as premature delivery (25%), respiratory distress syndrome (8%), pneumonia (8%) and deaths of 4 newborns SARS-CoV-2 was found mainly in syncytiotrophoblast cells at the maternal-fetal border of the placenta. Histological examination of the placenta revealed dense macrophage infiltration. Abnormal perfusion of fetal blood vessels or fetal vascular thrombosis was observed. Elevated levels of SARS-CoV-2 IgG or IgM antibodies in the umbilical cord blood were observed in nine newborns, reported as evidence of vertical infection. CONCLUSIONS The features of placental damage in women with COVID-19 are clearly different from the control group. Further research is needed to better understand how SARS-CoV-2 infection affects the placenta.
Ice Flavor–Related Discussions on Twitter: Content Analysis

Background The US Food and Drug Administration (FDA) recently restricted characterizing flavors in tobacco products. As a result, ice hybrid–flavored e-cigarettes, which combine a cooling flavor with fruit or other flavors (eg, banana ice), emerged on the market. Like menthol, ice-flavored e-cigarettes produce a cooling sensory experience. It is unclear if ice hybrid–flavored e-cigarettes should be considered characterizing flavors or menthol, limiting regulatory action. Monitoring the public’s conversations about ice-flavored e-cigarettes on Twitter may help inform the tobacco control community about these products and contribute to the US FDA policy targets in the future. Objective This study documented the themes pertaining to vaping and ice flavor–related conversations on Twitter. Our goal was to identify key conversation trends and ascertain users’ recent experiences with ice-flavored e-cigarette products. Methods Posts containing vaping-related (eg, “vape,” “ecig,” “e-juice,” or “e-cigarette”) and ice-related (ie, “Ice,” “Cool,” “Frost,” and “Arctic”) terms were collected from Twitter’s streaming application programming interface from January 1 to July 21, 2021. After removing retweets, a random sample of posts (N=2001) was selected, with 590 posts included in the content analysis. Themes were developed through an inductive approach. Theme co-occurrence was also examined. Results Many of the 590 posts were marked as (or consisted of) marketing material (n=306, 51.9%), contained positive personal testimonials (n=180, 30.5%), and mentioned disposable pods (n=117, 19.8%). Other themes had relatively low prevalence in the sample: neutral personal testimonials (n=45, 7.6%), cannabidiol products (n=41, 7%), negative personal testimonials (n=41, 7%), “official” flavor description (n=37, 6.3%), ice-flavored JUUL (n=19, 3.2%), information seeking (n=14, 2.4%), and comparison to combustible tobacco (n=10, 1.7%). The most common co-occurring themes in a single tweet were related to marketing and disposable pods (n=73, 12.4%). Conclusions Our findings offer insight into the public’s experience with and understanding of ice-flavored e-cigarette products. Ice-flavored e-cigarette products are actively marketed on Twitter, and the messages about them are positive. Public health education campaigns on the harms of flavored e-cigarettes may help to reduce positive social norms about ice-flavored products. Future studies should evaluate the relationship between exposure to personal testimonials of ice-flavored vaping products and curiosity, harm perceptions, and experimentation with these products among priority populations.
Nurse and pharmacist systemic anti‐cancer therapy review clinics and their impact on patient experience and care: A systematic review

Abstract Aim To review the evidence of how nurse and pharmacist roles have been incorporated into the management of patients undergoing systemic anti‐cancer therapy (SACT) services and their impact on patient experience and care provision. Design Systematic Review. Data Sources Seven databases were searched on 10 April 2022. Review Methods Research studies that met defined inclusion criteria were included. Quantitative findings were converted into textual descriptions and combined with qualitative results for thematic analysis. Data were categorized and aggregated into themes. Heterogeneity of studies meant meta‐analysis was not possible. Results Fifteen papers were included. Three main themes were identified: advanced clinical practice (ACP) SACT service development; ACP skills and qualifications; and the impact of ACP SACT services on patient care and outcomes. There is a variation in tasks undertaken by nurses and pharmacists and role integration is restricted by limited physician engagement. Role titles used and skills and qualifications acquired differ and professional autonomy is variable. Qualitative studies were limited. Conclusion Evidence of how nursing and pharmacist ACP roles are implemented, what skills are essential and how roles are impacting patient experience and outcomes is limited. More research is required to explore patient and physician experience of, and satisfaction with multi‐professional care, alongside further evaluation of clinical delivery models.
Vibrio spp and other potential pathogenic bacteria associated to microfibers in the North-Western Mediterranean Sea

Microfibers, whether synthetic or natural, have increased dramatically in the environment, becoming the most common type of particles in the ocean, and exposing aquatic organisms to multiple negative impacts. Using an approach combining morphology (scanning electron microscopy-SEM) and molecular taxonomy (High-Throughput DNA Sequencing- HTS), we investigated the bacterial composition from floating microfibers (MFs) collected in the northwestern Mediterranean Sea. The average number of bacteria in 100 μm2 on the surface of a fiber is 8 ± 5.9 cells; by extrapolating it to a whole fiber, this represents 2663 ± 1981 bacteria/fiber. Attached bacterial communities were dominated by Alteromonadales, Rhodobacterales, and Vibrionales, including the potentially human/animal pathogen Vibrio parahaemolyticus. This study reveals a high rate of bacterial colonization on MFs, and shows that these particles can host numerous bacterial species, including putative pathogens. Even if we cannot confirm its pathogenicity based only on the taxonomy, this is the first description of such pathogenic Vibrio living attached to MFs in the Mediterranean Sea. The identification of MFs colonizers is valuable in assessing health risks, as their presence can be a threat to bathing and seafood consumption. Considering that MFs can serve as vector for potentially pathogenic microorganisms and other pollutants throughout the ocean, this type of pollution can have both ecological and economic consequences.
Influence of imaging quality on magnetic resonance-based pressure gradient measurements

In cardiovascular diagnostics, the knowledge of blood pressure is essential for the physician. Nowadays, blood pressures are usually obtained by catheter measurements or sphygmomanometric methods. These techniques suffer from different drawbacks in terms of invasiveness, observable vessels and the resolution of the pressure values, respectively. Magnetic resonance imaging (MRI) offers a promising approach to establish a method for blood pressure measurements that is able to overcome these difficulties. Phase-contrast MRI is used to acquire velocity-encoded data. Fluid pressure gradients can be derived from the measured velocities using the Navier-Stokes equations. Unfortunately, this technique is known to suffer from a strong sensitivity to imaging quality. Especially the low signal-to-noise ratios (SNR) of phase contrast MRI data combined with the limited spatial and temporal resolution could severely reduce the reliability of computations. In this paper, we analyze computations of blood pressure gradients based on phase contrast MRI measurements of steady and pulsatile flow in a phantom. The influence of image quality of the velocity-encoded data as well as of different segmentation techniques is evaluated. In case of steady flow, the pressure gradient values computed via Navier-Stokes equations show good agreement with theoretical values if physical a-priori knowledge is incorporated. If a pulsatile aortic flow profile is applied, the computed pressure gradients generally match catheter measurements well. Nevertheless, an underestimation of pressure gradient peaks is observed. Different segmentation techniques influence the size of root mean squared errors between computation and measurement as well as their reduction by the use of higher SNRs.
Germline Variants in DNA Damage Repair Genes and HOXB13 Among Black Patients With Early-Onset Prostate Cancer

PURPOSE Genetic studies of prostate cancer susceptibility have predominantly focused on non-Hispanic White men, despite the observation that Black men are more likely to develop prostate cancer and die from the disease. Therefore, we sought to identify genetic variants in Black patients diagnosed with early-onset prostate cancer. METHODS Whole-exome sequencing of germline DNA from a population-based cohort of Black men diagnosed with prostate cancer at age 62 years or younger was performed. Analysis was focused on a panel of DNA damage repair (DDR) genes and HOXB13. All discovered variants were ranked according to their pathogenic potential based upon REVEL score, evidence from existing literature, and prevalence in the cohort. Logistic regression was used to investigate associations between mutation status and relevant clinical characteristics. RESULTS Among 743 Black prostate cancer patients, we identified 26 unique pathogenic (P) or likely pathogenic (LP) variants in 14 genes (including HOXB13, BRCA1/2, BRIP1, ATM, CHEK2, and PALB2) among 30 men, or approximately 4.0% of the patient population. We also identified 33 unique variants of unknown significance in 16 genes among 39 men. Because of the rarity of these variants in the population, most associations between clinical characteristics did not achieve statistical significance. However, our results suggest that carriers for P or LP (P/LP) variants were more likely to have a first-degree relative diagnosed with DDR gene-associated cancer, have a higher prostate-specific antigen at time of diagnosis, and be diagnosed with metastatic disease. CONCLUSION Variants in DDR genes and HOXB13 may be important cancer risk factors for Black men diagnosed with early-onset prostate cancer, and are more frequently observed in men with a family history of cancer.
Perceived changes in symptoms and quality-of-life amongst patients with dizziness: A single-centre experience in Malaysia.

INTRODUCTION Dizziness is a common complaint by patients, yet it always presents as a diagnostic challenge to the attending clinician. An accurate diagnosis is essential to correctly administer the precise treatment regime, alleviate the symptoms, and improve the quality-of-life of patients who present with dizziness. A specialised vestibular clinic with a holistic approach of meticulous history-taking, complete physical examination, a collection of audiovestibular test battery, and facilities for vestibular rehabilitation was set up to assist in the management of these patients. This study aims to investigate the effect of vestibular clinic intervention on the symptoms and qualityof- life of patients who were managed in the vestibular clinic. MATERIALS AND METHODS A total of 64 new patients who were managed in the vestibular clinic were selected and the validated Malay - Vestibular Rehabilitation Benefit Questionnaire (My-VRBQ) was completed during the first and follow-up visits to measure the changes in symptoms and quality-of-life before and after receiving care at the vestibular clinic. RESULTS Our study showed that there was a positive effect of vestibular clinic intervention on the symptoms and quality-of-life of patients who were managed by the vestibular clinic. Statistically significant improvements were seen in the total My-VRBQ scores, symptoms scores, and quality-of-life scores. The subscale scores of dizziness, anxiety, and motion-provoked dizziness also showed statistically significant improvement among the patients who received care at the vestibular clinic. CONCLUSION This indicates that the vestibular clinic was an essential part of the work-up, diagnosis, and treatment of patients with dizziness; and a specialised vestibular clinic was able to bring about positive outcomes in the symptoms and quality-of-life of patients with balance disorders.

Spiritual comfort, spiritual support, and spiritual care: A simultaneous concept analysis

Abstract Background Spirituality is a dimension of life and the human being that should be included in holistic healthcare. One major barrier often described by nurses on implementing spirituality in practice relates to perceiving the concept of spirituality as subjective and sharing confounding similarities with other concepts. In this sense, the concepts of spiritual comfort, spiritual care, and spiritual support may require more distinct theoretical definitions aimed at clear and effective nursing interventions within spiritual care. Aim To provide a definition of spiritual comfort, spiritual support, and spiritual care. Methods Simultaneous concept analysis (SCA) of three concepts according to Haase et al., which is grounded on Rodgers' evolutionary view. The method was based on a literature review with the search of electronic databases on May 2020. Search and analysis have been blinded conducted by two reviewers. Results One hundred thirty‐six studies were included in the SCA. Findings suggest that spiritual comfort is an immediate state and an outcome. Spiritual support is related with an intimate and positive relationship with God. Spiritual care is defined as a complex and interactive process. Both spiritual support and spiritual care are grounded in a therapeutic context. Conclusion This SCA allowed the attributes of each concept to be identified and provides definitions that may facilitate the understanding of these concepts and promote the implementation of spirituality in nursing practice, but which has also led to future research on this topic.
Kernel Method Starting with Half-Normal Detection Function for Line Transect Density Estimation

In this article, we introduce the nonparametric kernel method starting with half-normal detection function using line transect sampling. The new method improves bias from O(h 2), as the smoothing parameter h → 0, to O(h 3) and in some cases to O(h 4). Properties of the proposed estimator are derived and an expression for the asymptotic mean square error (AMSE) of the estimator is given. Minimization of the AMSE leads to an explicit formula for an optimal choice of the smoothing parameter. Small-sample properties of the estimator are investigated and compared with the traditional kernel estimator by using simulation technique. A numerical results show that improvements over the traditional kernel estimator often can be realized even when the true detection function is far from the half-normal detection function.
The association between upper gastrointestinal endoscopic findings and internal radiation exposure in residents living in areas affected by the Chernobyl nuclear accident

Many people living around the Chernobyl Nuclear Power Plant (CNPP) have been exposed to 137Cs for several decades after the CNPP accident. Although half-life of 137Cs is about 30 years, some wild forest foodstuffs are contaminated by 137Cs even now. We pointed out in a previous report that low-dose internal radiation has been occasionally detected in people’s body. Moreover, some doctors in local hospitals have claimed that internal exposure from contaminated foodstuffs may affect the digestive organs and possibly cause gastrointestinal (GI) diseases. Thus, we attempt to assess whether internal radiation exposure affects digestive organs or not, and the possible factors that influence digestive organs. Overall, 1,612 residents were assessed for internal 137Cs concentration using Whole-Body Counter and their digestive organs were screened with upper GI endoscopy from 2016–2018 in the Zhytomyr region, Ukraine. All participants answered to the questionnaire including their background, intake of wild forest foodstuff, intake frequency, smoking habits, and alcohol consumption. We checked the number of upper GI endoscopic diagnosis per person to assess the extent of damage to the upper digestive organs. Next, we statistically analyzed associations between this number and age, sex, level of internal exposure dose, alcohol consumption, wild forest foodstuff intake, and smoking. Consequently, we revealed that the number of GI diagnosis is significantly increased by factors such as sex, intake of wild forest foodstuff, and alcohol consumption. However, the average level of internal exposure of 137Cs and smoking did not relate to the number of GI diagnosis. Thus, the results of multiple regression revealed that alcohol consumption is independently related to the number of GI diagnosis that is most likely accompanied by the intake of wild forest foodstuff. In conclusion, the low-dose internal exposure may not affect the digestive organs of residents living around CNPP.
Figure skating: Increasing numbers of revolutions in jumps at the European and World Championships

Figure skating is associated with a high prevalence of sport-specific injuries and overuse symptoms. Impacts are of greater magnitude in jumps with more revolutions that are thus connected to a greater risk of injury. While figure skating programs seem to have recently increased in difficulty, performance trends have not yet been reported in the literature. We hypothesized increasing performance and decreasing age trends of the best athletes who competed at international level in recent years. Furthermore, we aimed to identify and analyse objective performance parameters and to assess a potential link between age and the risk of injury. The development of the number of double, triple and quadruple jumps in the singles figure skating events at the World and European Championships since the introduction of the new ISU Judging System in the 2004/2005 season was analysed using regression statistics and Student’s T-Tests. In all groups, the numbers of jumps with fewer rotations significantly decreased in the favour of jumps with more rotations. Women only started to perform jumps with four rotations in 2019. In the men, the number of quadruple jumps increased from an average of less than one to more than three in recent years (European and World Championships, both p < 0.001). In the European, but not in the World Championships, the average age increased in the men and decreased in the women (European Championships, men and women p = 0.006). Our study was the first to assess performance trends in elite figure skating. The incidence of injuries and overuse syndromes in figure skating needs to be monitored cautiously, as increases can be expected following recent gains in performance and jump complexity.
Investigating the relationship between inaccurate blood alcohol concentration estimates, harm and other negative consequences

Abstract Introduction Alcohol‐related harms place a significant burden on the Australian economy and health‐care system. The current study aims to: (i) explore the relationship between blood alcohol concentration (BAC) and self‐estimated blood alcohol concentration (EBAC); and (ii) determine whether BAC underestimation is related to an increased risk of experiencing physical aggression, verbal aggression, drink driving, ejection from a venue or refusal of service. Methods Patron street surveys were conducted in four night‐time entertainment precincts (NEP) across Queensland, Australia, between June 2016 and November 2018. Participants (N = 2144) reported on their EBAC and recent negative or harmful experiences in NEPs. BAC was measured via a breathalyser. Paired samples t tests were conducted to determine if patrons' BAC and EBAC were significantly different. Logistic regressions were conducted to examine whether BAC underestimation is a significant predictor of harm and negative outcomes. Results Analyses identified a small, significant difference between patron's BAC and EBAC. Patrons with a low BAC were more likely to overestimate their BAC, while patrons with higher BACs were more likely to underestimate their BAC. Moderately intoxicated patrons had the most precise BAC estimations. Patrons with a high BAC and who underestimated their intoxication level were more likely to have been recently ejected from licensed venues, compared to accurate estimators or over‐estimators. Discussion and Conclusions Overall, patrons are poor evaluators of their own intoxication level, which may have implications for their experiences in NEPs. The findings highlight the need for improved BAC education for patrons.
