Flager's portrayals of Southern lesbians in the late 20th century, interwoven with the experiences of Southern cuisine, history, identity, race, class, nationalism, and self-discovery, reveal in her plays a re-centering of Southern culture, a unique perspective forged by a marginalized identity.

The marine sponge Hippospongia lachne de Laubenfels was found to contain nine sterols, among them two novel 911-secosterols, hipposponols A (1) and B (2), plus five known analogues: aplidiasterol B (3), (3,5,6)-35,6-triol-cholest-7-ene (4), (3,5,6,22E)-35,6-triol-ergosta-7,22-diene (5), and a set of inseparable C-24 epimers of (3,5,6,22E)-35,6-triol-stigmasta-7,22-diene (6/7). The structures of isolated compounds received in-depth characterization, leveraging both HRESIMS and NMR data. DMAMCL molecular weight Cytotoxicity was observed in PC9 cells treated with compounds 2, 3, 4, and 5, with IC50 values spanning a range from 34109M to 38910M. Compound 4 exhibited cytotoxic activity against MCF-7 cells, with an IC50 of 39004M.

To explore patients' viewpoints concerning cognitive symptoms stemming from migraines, observing these symptoms throughout the pre-headache, headache, post-headache, and interictal stages.
Cognitive symptoms that are migraine-related are reported by people experiencing migraines, both during and between migraine episodes. Treatment initiatives are increasingly directed toward individuals with disabilities, due to their conditions. To enhance migraine treatment evaluation, the MiCOAS project seeks to develop a patient-centered core set of outcome measures. Incorporating the experiences of those living with migraine and the outcomes they prioritize is the project's core objective. The investigation considers the existence and impact on function of migraine-related cognitive symptoms, as well as their perceived effects on quality of life and the level of disability experienced.
Forty individuals, each self-reporting a medically confirmed migraine diagnosis, were recruited via a strategy of iterative purposeful sampling for semi-structured qualitative interviews. These interviews were conducted exclusively over audio-only web conferencing. Using thematic content analysis, researchers sought to identify critical concepts related to migraine and its cognitive effects. Recruitment proceeded without interruption until conceptual saturation became the definitive stop.
Participants reported experiencing symptoms mirroring migraine-associated language/speech, sustained attention, executive function, and memory impairments, present before, during, after, and between headache episodes. Specifically, 90% (36/40) noted at least one cognitive symptom prior to headache onset, 88% (35/40) during the headache itself, 68% (27/40) following the headache, and 33% (13/40) during the periods between headaches. From the participants experiencing cognitive issues before experiencing a headache, 81% (32/40) endorsed the presence of 2 to 5 cognitive symptoms. The headache phase yielded comparable findings. Participants' self-reported language/speech problems aligned with, for example, impairments in both receptive and expressive language skills, as well as articulation. Sustained attention problems included difficulty focusing, episodes of fogginess and confusion, and a notable sense of disorientation. Difficulties in the executive function domain included challenges with information processing and a reduced potential for effective planning and sound decision-making. Complaints about memory problems were ubiquitous throughout the entirety of the migraine episode.
A qualitative study on the patient experience of migraine highlights the commonality of cognitive symptoms, most pronounced in the run-up to and during headache episodes. These outcomes highlight the importance of assessing and addressing these cognitive difficulties.
A patient-level, qualitative study indicates that cognitive symptoms are regularly observed in individuals with migraine, specifically during the pre-headache and headache stages. These discoveries emphasize the necessity of both evaluating and improving these cognitive difficulties.

Patients afflicted with monogenic Parkinson's disease may experience varying survival outcomes, contingent upon the genetic factors underlying their condition. This study investigates patient survival in Parkinson's disease, differentiating by the presence of SNCA, PRKN, LRRK2, or GBA mutations.
Data from the national multicenter cohort study of French Parkinson Disease Genetics were applied. The period from 1990 to 2021 encompassed the recruitment of patients diagnosed with either sporadic or familial Parkinson's disease. A genetic analysis of the patient cohort was conducted to determine the presence or absence of mutations in the SNCA, PRKN, LRRK2, or GBA genes. Data on the vital status of individuals born in France was extracted from the National Death Register. Multivariable Cox proportional hazards regression was used to calculate hazard ratios (HRs) and their corresponding 95% confidence intervals (CIs).
In the 30-year follow-up of 2037 Parkinson's disease patients, a mortality rate of 889 was observed. Patients with mutations in PRKN (n=100, HR=0.41; p=0.0001) and LRRK2 (n=51, HR=0.49; p=0.0023) genes showed improved survival, as opposed to those without these mutations, whereas those with SNCA (n=20, HR=0.988; p<0.0001) or GBA (n=173, HR=1.33; p=0.0048) mutations demonstrated a decreased survival time.
Survival disparities exist in Parkinson's disease according to genetic variations, where individuals with SNCA or GBA mutations have higher mortality, in contrast to those with PRKN or LRRK2 mutations who demonstrate lower mortality. The diverse severities and disease progressions seen across various monogenic forms of Parkinson's disease are likely the reason behind these findings, impacting crucial aspects of genetic counseling and the selection of clinical trial benchmarks for targeted therapies. In the 2023 Annals of Neurology.
Genetic variations in Parkinson's disease are correlated with survival disparities; patients carrying SNCA or GBA gene mutations exhibit higher mortality rates, contrasting with those bearing PRKN or LRRK2 mutations who exhibit lower mortality rates. The different severities and disease progressions seen in monogenic forms of Parkinson's disease, in all likelihood, explain these findings, which has major implications for genetic counseling and the selection of parameters for upcoming focused treatment trials.

Examining if alterations in headache management self-efficacy partially account for the connection between post-traumatic headache-related disability and changes in the severity of anxiety symptoms.
Many cognitive-behavioral therapies for headaches emphasize the importance of stress reduction, including anxiety management strategies, but little research has focused on the specific processes that lead to improved functioning in individuals suffering from post-traumatic headache-related disability. An enhanced understanding of the mechanisms governing these debilitating headaches could potentially result in improved therapeutic interventions.
This secondary analysis, encompassing veterans (N=193) randomized to receive cognitive-behavioral therapy, cognitive processing therapy, or standard treatment, explored outcomes for persistent posttraumatic headaches. The study sought to determine the direct link between self-efficacy in managing headaches, the degree of disability associated with headaches, and the extent to which changes in anxiety symptoms acted as a partial mediator.
Statistically significant results were observed for the direct, mediated, and total pathways of mediated latent change. DMAMCL molecular weight Headache management self-efficacy exhibited a substantial, direct influence on headache-related disability, as indicated by the path analysis (b = -0.45, p < 0.0001; 95% confidence interval [-0.58, -0.33]). A statistically significant association was observed between the change in headache management self-efficacy scores and the change in Headache Impact Test-6 scores, with a moderate-to-strong effect size (b = -0.57, p < 0.0001; 95% CI = -0.73 to -0.41). Symptom severity of anxiety influenced an indirect impact (b = -0.012, p = 0.0003; 95% CI = [-0.020, -0.004]).
The observed enhancements in headache-related disability in this study were primarily associated with an increase in headache management self-efficacy, which was in turn influenced by changes in anxiety. The improvement in posttraumatic headache-related disability is plausibly mediated by enhanced headache management self-efficacy, with lower anxiety levels accounting for a portion of the beneficial effect.
Improvements in headache-related disability in this research were primarily tied to increases in headache management self-efficacy, this enhancement being facilitated by changes in anxiety levels. The observed decrease in post-traumatic headache-related disability likely results from improved self-efficacy in headache management, with anxiety reduction playing a contributing role.

Lower extremity muscle weakness and vascular dysfunction are recurring problems that individuals with a history of severe COVID-19 can experience long-term. Symptoms characteristic of post-acute sequelae of Sars-CoV-2 (PASC) are, unfortunately, not yet addressed by evidence-based treatments. In a double-blinded, randomized, controlled trial setting, we evaluated lower extremity electrical stimulation (E-Stim)'s capacity to address muscle deconditioning, a consequence of PASC. A total of 18 patients, diagnosed with lower extremity (LE) muscle deconditioning (n=18), underwent random allocation into either the intervention (IG) or control (CG) group. This resulted in the evaluation of 36 lower extremities. Both groups were subject to daily 1-hour E-Stim therapies focused on their gastrocnemius muscles during a four-week period; the device operated in the intervention group and was non-operational in the control group. The impact of four weeks of daily one-hour E-Stim treatments on plantar oxyhemoglobin (OxyHb) and gastrocnemius muscle endurance (GNMe) was examined. DMAMCL molecular weight At each study visit, OxyHb measurements were taken using near-infrared spectroscopy at baseline (t0), 60 minutes (t60), and 10 minutes post-E-Stim therapy (t70).
