Using Smartphone Technology to Track Real-Time Changes in Anxiety/Depression Symptomatology Among Florida Cannabis Users.

Objective: Recent scientific attention has focused on the therapeutic effectiveness of cannabis use on a variety of physical and mental ailments. The present study uses smartphone technology to assess self-reported experiences of Florida cannabis users to understand how cannabis may impact anxiety and depression symptomatology. Method: Several hundred Releaf App™ users from the state of Florida provided anonymous, real-time reports of their symptoms of anxiety and/or depression immediately before and after cannabis use sessions. Linear mixed-effects modeling was used to analyze the data at the symptom and user level. Results: Results showed that for the majority of users, cannabis use was associated with a significant decrease in depression and anxiety symptomatology. While symptom type, doses per session, consumption method, and CBD levels were significant predictors of relief change, their effect sizes were small and should be interpreted with caution. At the user level, those who had positive relief outcomes in anxiety reported more doses and sessions, and those in the depression group reported more sessions. Conclusions: Our results generally support the therapeutic effectiveness of cannabis against depression/anxiety symptomatology. Future work should include standardized statistics and effect size estimates for a better understanding of each variable's practical contribution to this area of study.

Inpatients' experiences of falls: A qualitative meta-synthesis.

OBJECTIVES: Identify and synthesize published qualitative research reporting inpatient experiences of a fall to determine novel insights and understandings of this longstanding complex problem. RESEARCH DESIGN: Qualitative meta-synthesis. METHODS: Online databases were searched to systematically identify published research reporting inpatient experiences of a fall. The included studies were inductively analysed and interpreted then reported as a meta-synthesis. DATA SOURCES: Databases Ovid MEDLINE, Embase, Ovid Emcare, CINAHL Complete, Scopus and ProQuest Dissertations and Theses Global were searched on 3rd August, 2023. RESULTS: From 10 included publications, four new themes of inpatients' experiences of a fall were constructed. Themes one, two and three related to antecedents of patient falls, and theme four related to consequences. Theme one, 'My foot didn't come with me: Physiological and anatomical changes', encompassed patients' experiences of medical conditions, medication, and anatomical changes. These aspects contributed to alterations in balance and strength, and misconceptions of capability in activities of daily (inpatient) living. Theme two, 'I was in a hurry: Help-seeking', encompassed patients' experiences striving for independence while balancing power and control, minimizing their own needs over care of others', and unavailability of support. Theme three, 'I couldn't find the call light: Environment and equipment', encompassed patients' experiences of not being able to reach or use equipment, and environment changes. Theme four, 'It was my fault too: Blame and confidence', encompassed patients' expressions of blame after their fall, blame directed at both themselves and/or others, and impacts on confidence and fear in mobilizing. CONCLUSIONS: Inpatient falls are embedded in a complexity of individual, relational, and environmental factors, yet there are potential ways forward both informed and led by the patient's voice. Strength-based approaches to address the tenuous balance between independence and support may be one opportunity to explore as a next step in complementing the existing multifaceted interventions. IMPACT: Inpatient falls are a complex and costly health safety and quality problem. Despite global initiatives in the prevention of inpatient falls, they remain intractable. This meta-synthesis provides an in-depth exploration of extant qualitative data on patients' experiences of falls in hospitals. Four themes were constructed expressing the inpatients' experiences: physiological and anatomical changes, help-seeking, environment and equipment, and blame and confidence. Novel considerations for future investigation are offered, drawing from self-determination theory and positive psychological interventions. IMPLICATIONS FOR PATIENT CARE: This meta-synthesis elicits new considerations for future interventions based on people's experiences of their fall in hospital, offering healthcare professionals novel directions in fall prevention. REPORTING METHOD: The review was reported according to the Enhancing transparency in reporting the synthesis of qualitative research statement (ENTREQ; Tong et al., 2012). PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution. REGISTRATION: PROSPERO CRD42023445279.

Seventy-Two-Hour Reutilization After Telemedicine Visits in Academic Pediatric Primary Care.

Telemedicine has expanded due to the COVID-19 pandemic. However, the health care usage after telemedicine visits compared with similar in-person visits is not known. This study compared the 72-hour health care reutilization after telemedicine visits and in-person acute encounters in a pediatric primary care office. A retrospective cohort analysis was performed in a single quaternary pediatric health care system between March 1, 2020, and November 30, 2020. Reutilization information was collected for 72 hours following the index visit and included subsequent encounters within the health care system. The 72-hour reutilization rate for telemedicine encounters was 4.1% compared with 3.9% for in-person acute visits. Of revisits, patients who had a telemedicine visit most often sought additional care at the medical home, and patients with an in-person visit most often sought additional care to the emergency department or urgent care. Telemedicine does not result in higher total health care reutilization.

Consumption and tax gains attributable to Covid-19 vaccinations in 12 EU countries with low vaccination rates.

BACKGROUND: The Covid-19 pandemic is an economic and a health crisis. Households reduced consumption expenditures as large-scale physical distancing measures, lower disposable incomes and fear of infection when engaging in many types of economic activity took hold. This, in turn, reduced domestic tax revenues at a time when governments were facing increased financial pressures to strengthen and sustain welfare states. METHODS: We developed a simulation model, the Covid-19 Taxination Simulator, to estimate potential economic gains and tax revenues attributable to vaccine rollouts. We apply the model to 12 European Union countries which had low vaccination rates at the beginning of 2022. RESULTS: The highest growth in aggregate personal consumption expenditure attributable to Covid-19 vaccines administered as of January 2022 is in Greece (10.8%), Slovenia (8.6%) and Czechia (8.6%), while the lowest is in Bulgaria (2.2%) and Slovakia (2.1%). If countries had vaccinated 85% of their adult population, the largest gains in consumption tax revenues would be expected in Romania (830 million Euros) and Poland (738 million Euros). Consumption tax revenues generated by meeting the 85% of the adult population target would, on their own, be large enough to fully cover the costs of expanding the vaccine rollout itself in Estonia, Latvia, Slovenia, Croatia, Czechia, Hungary and Greece. CONCLUSION: Covid-19 vaccination rollouts not only save lives and relieve pressures on health systems, they also support economic growth and generate additional tax revenues. These revenues can partially offset the costs of vaccines programmes themselves.

An Assessment of a Socioeconomic Risk Screening Tool for Telemedicine Encounters in Pediatric Primary Care: A Pilot Study.

Socioeconomic adversity negatively affects child health. Telemedicine use in pediatrics is rapidly expanding. We piloted a socioeconomic risk screening tool within telemedicine visits. Using chart review, our primary aim was to assess the rates of screen completion, risk identification, and referral generation during telemedicine visits. Our secondary aim was to assess family satisfaction and barriers to connecting with referrals/interventions through follow-up telephone interviews. This study included 179 telemedicine encounters. The screening tool was completed in 63% of encounters and was positive in 5% of encounters. Of those who identified socioeconomic risks, 90% received a referral/intervention (social work consultation, food pantry, etc.). During follow-up calls, families expressed satisfaction with telemedicine, though 31% described difficulty connecting with the recommended services. High rates of socioeconomic risk screening resulting in interventions are achievable during telemedicine visits. Further work is needed to identify optimal socioeconomic risk screening questions and opportunities, and to ensure successful interventions.

Male infertility and somatic health - insights into lipid damage as a mechanistic link.

Over the past decade, mounting evidence has shown an alarming association between male subfertility and poor somatic health, with substantial evidence supporting the increased incidence of oncological disease, cardiovascular disease, metabolic disorders and autoimmune diseases in men who have previously received a subfertility diagnosis. This paradigm is concerning, but might also provide a novel window for a crucial health reform in which the infertile phenotype could serve as an indication of potential pathological conditions. One of the major limiting factors in this association is the poor understanding of the molecular features that link infertility with comorbidities across the life course. Enzymes involved in the lipid oxidation process might provide novel clues to reconcile the mechanistic basis of infertility with incident pathological conditions. Building research capacity in this area is essential to enhance the early detection of disease states and provide crucial information about the disease risk of offspring conceived through assisted reproduction.

Integration and Impact of Telemedicine in Underserved Pediatric Primary Care.

Telemedicine, more novel in provision of pediatric care, rapidly expanded due to the recent coronavirus disease 2019 pandemic. This study aimed to determine the feasibility of telemedicine for acute and chronic care provision in an underserved pediatric primary care center. Items assessed included patient demographic data, chief complaint, and alternative care locations if telemedicine was not available. In our setting, 62% of telemedicine visits were for acute concerns and 38% for chronic concerns. Of acute telemedicine visits, 16.5% of families would have sought care in the Emergency Department/Urgent Care, and 11.3% would have opted for no care had telemedicine not been offered. The most common chronic issues addressed were attention deficit hyperactivity disorder (80.3%) and asthma (16.9%). Racial disparities existed among our telemedicine visits with Black patients utilizing telemedicine services less frequently than non-Black patients. Telemedicine is feasible for pediatric acute and chronic care, but systems must be designed to mitigate widening racial disparities.

Male Infertility: Shining a Light on Lipids and Lipid-Modulating Enzymes in the Male Germline.

Despite the prevalence of male factor infertility, most cases are defined as idiopathic, thus limiting treatment options and driving increased rates of recourse to assisted reproductive technologies (ARTs). Regrettably, our current armory of ARTs does not constitute therapeutic treatments for male infertility, thus highlighting an urgent need for novel intervention strategies. In our attempts to fill this void, we have come to appreciate that the production of pathological levels of oxygen radicals within the male germline are a defining etiology of many idiopathic infertility cases. Indeed, an imbalance of reactive oxygen species can precipitate a cascade of deleterious sequelae, beginning with the peroxidation of membrane lipids and culminating in cellular dysfunction and death. Here, we shine light on the importance of lipid homeostasis, and the impact of lipid stress in the demise of the male germ cell. We also seek to highlight the utility of emerging lipidomic technologies to enhance our understanding of the diverse roles that lipids play in sperm function, and to identify biomarkers capable of tracking infertility in patient cohorts. Such information should improve our fundamental understanding of the mechanistic causes of male infertility and find application in the development of efficacious treatment options.

Mechanistic Insight into the Regulation of Lipoxygenase-Driven Lipid Peroxidation Events in Human Spermatozoa and Their Impact on Male Fertility.

A prevalent cause of sperm dysfunction in male infertility patients is the overproduction of reactive oxygen species, an attendant increase in lipid peroxidation and the production of cytotoxic reactive carbonyl species such as 4-hydroxynonenal. Our previous studies have implicated arachidonate 15-lipoxygenase (ALOX15) in the production of 4-hydroxynonenal in developing germ cells. Here, we have aimed to develop a further mechanistic understanding of the lipoxygenase-lipid peroxidation pathway in human spermatozoa. Through pharmacological inhibition studies, we identified a protective role for phospholipase enzymes in the liberation of peroxidised polyunsaturated fatty acids from the human sperm membrane. Our results also revealed that arachidonic acid, linoleic acid and docosahexanoic acid are key polyunsaturated fatty acid substrates for ALOX15. Upon examination of ALOX15 in the spermatozoa of infertile patients compared to their normozoospermic counterparts, we observed significantly elevated levels of ALOX15 protein abundance in the infertile population and an increase in 4-hydroxynonenal adducts. Collectively, these data confirm the involvement of ALOX15 in the oxidative stress cascade of human spermatozoa and support the notion that increased ALOX15 abundance in sperm cells may accentuate membrane lipid peroxidation and cellular dysfunction, ultimately contributing to male infertility.

Differential cell death decisions in the testis: evidence for an exclusive window of ferroptosis in round spermatids.

Oxidative stress is a major aetiology in many pathologies, including that of male infertility. Recent evidence in somatic cells has linked oxidative stress to the induction of a novel cell death modality termed ferroptosis. However, the induction of this iron-regulated, caspase-independent cell death pathway has never been explored outside of the soma. Ferroptosis is initiated through the inactivation of the lipid repair enzyme glutathione peroxidase 4 (GPX4) and is exacerbated by the activity of arachidonate 15-lipoxygenase (ALOX15), a lipoxygenase enzyme that facilitates lipid degradation. Here, we demonstrate that male germ cells of the mouse exhibit hallmarks of ferroptosis including; a caspase-independent decline in viability following exposure to oxidative stress conditions induced by the electrophile 4-hydroxynonenal or the ferroptosis activators (erastin and RSL3), as well as a reciprocal upregulation of ALOX15 and down regulation of GPX4 protein expression. Moreover, the round spermatid developmental stage may be sensitized to ferroptosis via the action of acyl-CoA synthetase long-chain family member 4 (ACSL4), which modifies membrane lipid composition in a manner favourable to lipid peroxidation. This work provides a clear impetus to explore the contribution of ferroptosis to the demise of germline cells during periods of acute stress in in vivo models.

Mixed germ cell tumor composed of a tridermic testicular teratoma and seminoma in a rooster.

A 5-y-old backyard Araucana-Americana rooster was presented to the regional diagnostic laboratory with a history of progressive lethargy and respiratory signs. Autopsy revealed a single large mass of testicular origin in the coelomic cavity, causing compression of other organs. Histologically, the mass was 1 neoplasm with mixed components of 2 different germ cell tumors, namely a teratoma composed of elements of all 3 primordial germ cell lines (ectoderm, mesoderm, and endoderm), and a seminoma consisting of round or polygonal cells arranged in sheets supported by a scant fibrovascular stroma. Teratomas and seminomas are both considered to be uncommon neoplasms in poultry medicine. A testicular teratoma is composed of mature embryonic tissue derived from at least 2 of the 3 germinal layers. Seminomas and teratomas both arise from the germinal epithelium of seminiferous tubules and are classified as germ cell tumors. This neoplastic mass thus is a rare case of a mixed germ cell tumor.

Oxidative Stress in the Male Germline: A Review of Novel Strategies to Reduce 4-Hydroxynonenal Production.

Germline oxidative stress is intimately linked to several reproductive pathologies including a failure of sperm-egg recognition. The lipid aldehyde 4-hydroxynonenal (4HNE) is particularly damaging to the process of sperm-egg recognition as it compromises the function and the stability of several germline proteins. Considering mature spermatozoa do not have the capacity for de novo protein translation, 4HNE modification of proteins in the mature gametes has uniquely severe consequences for protein homeostasis, cell function and cell survival. In somatic cells, 4HNE overproduction has been attributed to the action of lipoxygenase enzymes that facilitate the oxygenation and degradation of ω-6 polyunsaturated fatty acids (PUFAs). Accordingly, the arachidonate 15-lipoxygenase (ALOX15) enzyme has been intrinsically linked with 4HNE production, and resultant pathophysiology in various complex conditions such as coronary artery disease and multiple sclerosis. While ALOX15 has not been well characterized in germ cells, we postulate that ALOX15 inhibition may pose a new strategy to prevent 4HNE-induced protein modifications in the male germline. In this light, this review focuses on (i) 4HNE-induced protein damage in the male germline and its implications for fertility; and (ii) new methods for the prevention of lipid peroxidation in germ cells.

Pharmacological inhibition of arachidonate 15-lipoxygenase protects human spermatozoa against oxidative stress.

One of the leading causes of male infertility is defective sperm function, a pathology that commonly arises from oxidative stress in the germline. Lipid peroxidation events in the sperm plasma membrane result in the generation of cytotoxic aldehydes such as 4-hydroxynonenal (4HNE), which accentuate the production of reactive oxygen species (ROS) and cause cellular damage. One of the key enzymes involved in the metabolism of polyunsaturated fatty acids to 4HNE in somatic cells is arachidonate 15-lipoxygenase (ALOX15). Although ALOX15 has yet to be characterized in human spermatozoa, our previous studies have revealed a strong link between ALOX15 activity and the levels of oxidative stress and 4HNE in mouse germ cell models. In view of these data, we sought to assess the function of ALOX15 in mature human spermatozoa and determine whether the pharmacological inhibition of this enzyme could influence the level of oxidative stress experienced by these cells. By driving oxidative stress in vitro with exogenous H2O2, our data reveal that 6,11-dihydro[1]benzothiopyrano[4,3-b]indole (PD146176; a selective ALOX15 inhibitor) was able to significantly reduce several deleterious, oxidative insults in spermatozoa. Indeed, PD146176 attenuated the production of ROS, as well as membrane lipid peroxidation and 4HNE production in human spermatozoa. Accordingly, ALOX15 inhibition also protected the functional competence of these cells to acrosome react and bind homologous human zonae pellucidae. Together, these results implicate ALOX15 in the propagation of oxidative stress cascades within human spermatozoa and offer insight into potential therapeutic avenues to address male in fertility that arises from oxidative stress.

Assessing Delaware Parents' Knowledge, Attitudes and Preferences About Long Acting Reversible Contraceptives for Teens Using Participatory Action Research.

To decrease barriers to long-acting reversible contraception (LARC) for teens, this study aimed to reveal knowledge, attitudes, and beliefs that parents have about LARC. METHODS: A participatory action research approach was used. We recruited a diverse group of community researchers who participated in all phases of our study. Four focus groups were recruited using snowball sampling. Two researchers used a values coding process to code data independently. The team met to identify emerging themes. RESULTS: The 46 parents were predominately female and ethnically diverse. Preventing teen pregnancy was salient although a double standard between parents of boys and girls became apparent. A key theme that emerged was the importance of prevention of sexually transmitted infections (STIs). There were some reservations about LARC provision in school-based health centers. Another theme was the need for access to confidential birth control for other teens but not for their own teens. Lastly, the advantages of LARC mentioned were effectiveness and ease of use. The disadvantages were increased STIs, risky behavior, hormonal changes, and side effects. CONCLUSION: Most of the parents in our study had limited knowledge of LARC. They were aware of its benefits but were uneasy about actual and perceived side effects.

Implementation of a Brief Abuse and Basic Needs Tool: Impact on Utilization of Social Services in Ambulatory Medical Clinics.

Domestic violence (DV) screening has become increasingly common in recent years; however, many organizations still do not practice universal screening, and there is considerable debate concerning the best screening tool for detecting DV. The current research suggests that a brief tool would be ideal and that existing brief tools are comparable to more extensive instruments. Per Joint Commission standards, the ambulatory clinics at West Virginia University Hospitals instituted the use of the Functional Health Screening (FHS), a three-item tool that screens for unexplained weight changes, DV, and basic needs deficits. This tool is administered at the beginning of every outpatient clinic visit. This study includes a retrospective chart review to investigate the detection rate of this tool for DV and basic needs deficits, the increased utilization of social services, and nursing attitudes concerning FHS.

Inhibition of arachidonate 15-lipoxygenase prevents 4-hydroxynonenal-induced protein damage in male germ cells.

Lipid peroxidation products, such as 4-hydroxynonenal (4HNE), are causative agents responsible for extensive protein damage within the male and female germlines. Recently, we have demonstrated that 4HNE production can initiate the proteolytic degradation of the molecular chaperone Heat Shock Protein A2 (HSPA2) in male germ cells. These events may be partially responsible for HSPA2 deficiency in the spermatozoa of patients that repeatedly fail in vitro fertilization. Given this, mechanisms that limit the production of 4HNE will be highly advantageous for the preservation of male fertility. The propagation of 4HNE in somatic cells has been linked to the enzymatic actions of arachidonate 15-lipoxygenase (ALOX15), a member of the lipoxygenase family of proteins. In view of this association, this study sought to explore ALOX15 as a physiological target to manipulate the levels of 4HNE produced in the male germline. Herein, we have demonstrated that ALOX15 is markedly upregulated in response to oxidative stress in round spermatids and the GC-2 cell line. Pharmacological inhibition of ALOX15 in GC-2 cells resulted in a significant reduction in both mitochondrial and cytoplasmic reactive oxygen species, as well as a dramatic reduction in 4HNE. Importantly, the reduced bioavailability of this aldehyde appears to confer positive downstream effects to its target proteins such that HSPA2 could be protected from damage by 4HNE. Taken together, these results suggest that the actions of ALOX15 are intimately tied to the production of 4HNE. Thus, the ALOX15 protein may be a promising new target for the mitigation of germline oxidative stress.

A Shotgun Proteomics Approach Reveals a New Toxic Role for Alzheimer's Disease Aß Peptide: Spliceosome Impairment.

Proteomic changes have been described in many neurodegenerative diseases, including Alzheimer's disease (AD). However, the early events in the onset of the pathology are yet to be fully elucidated. A cell model system in which LAN5 neuroblastoma cells were incubated for a short time with a recombinant form of Aß42 was utilized. Proteins extracted from these cells were subjected to shotgun proteomics analysis by LTQ-Orbitrap-MS followed by label-free quantitation. By bioinformatics tools we found that the most significant of those found to be up-regulated were related to cytoskeletal dynamics (Rho related) and membrane-related processes. The most significant of the down-regulated proteins were hnRNP-related. In particular, hnRNPs involved in ribosomal biogenesis and in splicing were down-regulated. The latter of these processes stood out as it was highlighted ubiquitously and with the highest significance in the results of every analysis. Furthermore, our findings revealed down-regulation at every stage of the splicing process through down-regulation of every subunit of the spliceosome. Dysregulation of the spliceosome was also confirmed using a Western blot. In conclusion, these data suggest dysregulation of the proteins and processes identified as early events in pathogenesis of AD following Aß accumulation.

Maltreatment and depression in adolescent sexual offenders with an autism spectrum disorder.

This study examined the self-reported presence and severity of abuse, neglect, and depressive symptoms for 43 adolescents adjudicated delinquent due to a sexual offense. Twenty-seven of the adolescent sexual offenders were also diagnosed with an autism spectrum disorder, and 16 did not carry an autism spectrum disorder diagnosis. Both groups reported moderate to high levels of abuse and neglect. Adolescent sexual offenders with an autism spectrum disorder reported significantly higher depressive symptoms than those without an autism spectrum disorder. Furthermore, of the group with an autism spectrum disorder, those reporting severe levels of emotional abuse and/or emotional neglect were more likely to also have depressive symptoms. Results suggest a need to tailor treatment programs to match the unique needs of sexual offenders.
