Iron and iron-containing compounds are essential for bacterial virulence and host infection. Hemin is an important supplement compound for bacterial survival in an iron-deficient environment. Despite strong interest in hemin metabolism, the detailed mechanism of hemin transportation in Gram-positive bacteria is yet to be reported. The results of our study revealed that the homologous proteins of SPD_0310 were significantly conservative in Gram-positive bacteria (P  less then  0.001), and these proteins were identified as belonging to an uncharacterized protein family (UPF0371). The results of thermodynamic and kinetic studies have shown that SPD_0310 has a high hemin-binding affinity. Interestingly, we found that the crystal structure of SPD_0310 presented a homotetramer conformation, which is required for hemin binding. SPD_0310 can interact with many hemin-binding proteins (SPD_0090, SPD_1609, and GAPDH) located on the cell surface, which contributes to hemin transfer to the cytoplasm. It also has a high af bacteria has rarely been studied. SPD_0310 belongs to the UPF0371 family of proteins, and results of homology analysis and evolutionary tree analysis suggested that it was widely distributed and highly conserved in Gram-positive bacteria. However, the function of the UPF0371 family remains unknown. We successfully determined the crystal structure of apo-SPD_0310, which is a homotetramer. We found that cytoplasmic protein SPD_0310 with a special tetramer structure has a strong hemin-binding ability and interacts with many iron transporters, which facilitates hemin transfer from the extracellular space to the cytoplasm. The results of detailed functional analyses indicated that SPD_0310 may function as a hemin transporter similar to hemoglobin in animals and contributes to bacterial iron homeostasis and virulence. This study provides a novel target for the development of antimicrobial drugs against pathogenic Gram-positive bacteria.
Debate centering on the management of anterior shoulder instability (ASI) in recent years has led to many randomized controlled trials (RCTs) being published on the topic. The fragility index (FI) has subsequently emerged as a novel method of assessing significant findings reported in RCTs, particularly those with small sample sizes.

To evaluate the FI of statistically significant findings in RCTs that reported the outcomes of management strategies of patients with ASI.

Systematic review; Level of evidence, 1.

Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, 2 independent reviewers performed a systematic review of RCTs focusing on the outcomes of management strategies of patients with ASI. There were 3 main categories of RCTs included (1) nonoperative management in internal rotation (IR) versus external rotation (ER), (2) nonoperative management versus a surgical intervention, and (3) surgical management with arthroscopic Bankart repair versus open Bankart outcomes of management strategies for patients with ASI was high, suggesting a moderate fragility of statistically significant outcomes including recurrence, revision stabilization, and return to play.Reports estimate between 1.6-3.8 million sports-related concussions occur annually, with 30% occurring in youth male American football athletes. Many studies report neurophysiological changes in these athletes, but the exact reasons for these changes remain elusive. Investigation of injury mechanics highlights a need to address how player position might impact these changes. Here, 55 high school American football athletes (20 linemen; 35 non-linemen) underwent magnetic resonance spectroscopy four times over the course of a football season-once prior to the season (Pre), twice during (In1, In2), and once following (Post) to quantify metabolites (N-acetyl aspartate, choline, creatine, myo-inositol, and glutamate/glutamine) in the dorsolateral prefrontal cortex (DLPFC) and primary motor cortex (M1). Head acceleration events (HAEs) were monitored at each practice and game. Spectroscopic and HAE data were analyzed by imaging session and player position. Linear regression analyses were conducted between metabolite levels and HAEs, and metabolite levels in football athletes were compared with age-and gender-matched non-contact athletes. Across-season (i.e., between Pre and In1, In2, Post), different DLPFC and M1 metabolites decreased (p  less then  0.05) according to player position (i.e., linemen vs. non-linemen). The majority of regression results involved DLPFC metabolites in linemen, where metabolite levels were higher from Pre to Post, with increasing HAE load. Comparisons with control athletes revealed higher metabolite levels in football athletes both before and after the season. This study highlights the importance of player position when conducting analyses on American football athletes and demonstrates elevated DLPFC and M1 brain metabolites in football athletes compared with control athletes at both Pre and Post, suggesting potential HAE-related neurocompensatory mechanisms.Objectives To assess the change of storage symptoms (SS) and their impact on quality of life in men undergoing thuliumYAG laser enucleation of the prostate (ThuLEP) for benign prostatic hyperplasia (BPH). Materials and Methods BPH patients requiring surgery were prospectively evaluated (April 2019-October 2020). Inclusion criteria International Prostate Symptom Score (IPSS) ≥8, maximum urinary flow rate ≤15 mL/s, and urinary retention. Exclusion criteria previous urethral/prostatic surgery, pelvic irradiation, bladder/prostate cancer, neurogenic bladder, concomitant transurethral surgery, and active urinary tract infection. IPSS, International Continence Society-Overactive Bladder (ICIQ-OAB) and International Continence Society-Overactive Bladder Quality of Life (ICIQ-OABq) scores were gathered before surgery and 1, 3, 6, and 12 months after surgery. Results In total, 117 men were included. Mean age was 68.0 ± 7.7 years. Mean prostate volume was 86.6 ± 34 cc. Mean IPSS subscore was 8.7 ± 3.1 and 11.7 ± 4.7 for storage and voiding symptoms, respectively. Mean ICIQ-OAB was 29.1 ± 16.8. Mean ICIQ-OABq was 80.3 ± 30.6. Voiding IPSS decreased 72.8% at 1 month, whereas the reduction of storage IPSS was 38.0%. ICIQ-OAB decreased 49.6% at 1 month. ICIQ-OABq showed a 30.0% reduction. One year after surgery, the reduction of voiding IPSS was 94.8%, ICIQ-OAB 85.5%, storage IPSS 76.7%, and ICIQ-OABq 60.5%. Urge incontinence was present in 26.5% of men at 1 month, 15.4% at 3 months, and 4.3% at 6 months. Four (3.4%) patients complained of urge incontinence 12 months after surgery. Conclusion Both storage and voiding lower urinary tract symptoms significantly decreased after ThuLEP, but storage symptoms showed less reduction with a significant impact on patients' quality of life, particularly during the first 3 months.Introduction Because it is a chronic disease of progressive evolution, heart failure requires nursing attitudes and practices that are articulated with palliative care, implemented in an interdisciplinary team along with patients and their families. Objective Identifying nurses' attitudes and practices in palliative care in cardiology. Method Integrative literature review. The searches were carried out in the following bases Google Scholar, Virtual Health Library, LILACS, SciELO, Embase, MEDLINE, CINAHL, and Scopus; through the terms Palliative Care AND Cardiology AND Nursing. Results We identified 1298 studies published in the last five years, 14 of which have been selected for the scope of this review. Nurse attitudes and practices were characterized as approach to symptom control; promotion of comfort and well-being; integrality of care and family orientation; effective communication among patients, family members and nursing team; timely evaluation for palliative care. Most of the studies included in this review have evidence level 2C (n = 7) and 2B (n = 4). Therefore, the results can be interpreted as reliable. Conclusions This study makes important contributions to the practice of nurses in palliative care for heart failure. Based on the evidence collected, nurses can develop actions with the nursing team and with the interdisciplinary team related to direct patient and family care, as well as professional training. However, the field lacks studies showing the practices and actions implemented by the nursing team.Background Treatment of pelvic venous disorders (PVD) including pelvic congestion syndrome (PCS) are often delayed due to its varying clinical manifestations. Patients and methods Patient referral was based on a literature- and personal experience-derived clinical "PCS screening score" (higher score points indicate greater likelihood with a maximum score of 10 points). We studied consecutive women who were (i) referred for vascular assessment and treatment to the University Hospital Zurich (2017-2021), (ii) had a PCS score ≥3 points, (iii) had evidence of obstructive or non-obstructive PVD by duplex sonography or cross-sectional imaging, and (iv) underwent endovascular therapy. see more The primary outcome was change in symptom severity after endovascular therapy (i) freedom from symptoms, (ii) improvement with residual symptoms, (iii) no improvement. Results We included 43 women (mean age 36 years) 81% had previous pregnancy, 19% endometriosis. The median PCS score was 7 (IQR 5-9) points. Chronic lower-abdominal painciated with a low rate of complications.Background Some levothyroxine (LT4)-treated hypothyroid patients report a constellation of persistent and distressing cognitive symptoms that has been termed brain fog. This narrative review focuses on attempts to define and measure hypothyroid-associated brain fog, summarize possible etiologies and contributing factors, present treatment options, and propose avenues for future research. Methods Published literature was reviewed to summarize available information on patient-reported symptoms associated with brain fog in hypothyroidism, as well as objective evidence of impairment based on neurocognitive testing and functional imaging studies. Given the limited information specific for hypothyroid-associated brain fog, relevant data from other medical conditions associated with brain fog were also reviewed and incorporated into recommendations for clinical care and future research areas. Results Hypothyroid-associated brain fog has not been well defined or quantitated, and the underlying pathophysiology is unclilitation is an underutilized technique that is beneficial in other medical conditions associated with brain fog and could improve symptoms in hypothyroid people. The limitations in our current knowledge and questions presented throughout this review highlight a major need for clinical research in this understudied area. Future research should include attention to standardization of survey instruments to quantitate brain fog in hypothyroid people, as well as rigorously designed intervention studies.Lamin A phosphorylation/de-phosphorylation is an important process during cells division as it allows for nuclear envelope (NE) disassembly at mitotic entry and its re-assembly during mitotic exit. Several kinases have been identified as responsible for these phosphorylations, but no protein phosphatase has been implicated in their reversal. One of the mitotic phosphosites in lamin A responsible for its dynamic behaviour is serine 22 (S22) which is de-phosphorylated during mitotic exit. Recent evidence has also linked the nuclear pool of lamin A S22ph in interphase to gene expression regulation. Previous work suggested that the phosphatase responsible for lamin A S22 de-phosphorylation is chromatin bound and interacts with lamin A via SUMO-SIM motives. We have previously reported that Repo-Man/protein phosphatase 1 (PP1) is a chromatin-associated phosphatase that regulates NE reformation. Here we propose that Repo-Man/PP1 phosphatase mediates lamin A S22 de-phosphorylation. We indeed show that depletion of Repo-Man leads to NE defects, causes hyperphosphorylation of lamin A S22 that can be rescued by a wild-type but not a SUMOylation-deficient mutant.
