Abstract Globally, an estimated 300 million individuals have sickle cell trait (SCT), the carrier state for sickle cell disease (SCD). Although SCD is associated with increased morbidity and shortened life span, SCT has a life span comparable with that of the general population. However, “sickle cell crisis” has been used as a cause of death for decedents with SCT in reports of exertion-related death in athletes, military personnel, and individuals in police custody. To appraise this practice, the American Society of Hematology convened an expert panel of hematologists and forensic pathologists to conduct a systematic review of the literature relating to the occurrence of sickle cell pain crises and exertion-related mortality in people with SCT. Multiple bibliographic databases were searched with controlled vocabulary and keywords related to “sickle cell trait,” “vaso-occlusive pain,” and “death,” yielding 18 of 1474 citations. Independent pairs of reviewers selected studies and extracted data. We found no studies comparing uncomplicated acute pain crises in individuals with SCT and SCD. Additionally, no study was identified to support the occurrence of acute vaso-occlusive pain crises in individuals with SCT. Furthermore, this systematic review did not identify any evidence to support an association between SCT and sudden unexplained death in the absence of exertion-related rhabdomyolysis. We conclude that there are no data to support the diagnosis of acute vaso-occlusive sickle cell crisis as a cause of death in SCT, nor does the available evidence support the use of SCT as a cause of exertion-related death without rhabdomyolysis.

Purpose: Fatigue is one of the most common and disabling symptoms experienced by people with inflammatory bowel disease; however, interventions to treat fatigue are limited. The purpose of this systematic review is to examine the relationship between sleep deficiency and fatigue in adults with inflammatory bowel disease and to describe the demographic and clinical factors associated with fatigue to inform future intervention work. Methods: We conducted a systematic review and reported the results using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search was conducted using MEDLINE, EMBASE, PsycINFO, CINAHL, and CENTRAL on 3/7/24. We included studies with adults (≥18 years of age) who had a diagnosis of inflammatory bowel disease (Crohn’s disease, ulcerative colitis, or indeterminate colitis) and measured fatigue and sleep using a validated self-report questionnaire or objective measurement. Results: Twenty-two studies met inclusion criteria for a total sample of 16 927, of whom 58.7% (n = 9937) had Crohn’s disease, and 66.3% (n = 11 226) were female. 56.1% of the participants experienced fatigue and 66.3% experienced sleep deficiency. Sleep quality and insomnia were consistently associated with fatigue. Baseline poor sleep quality was associated with persistent and worsening fatigue over 12 to 24 months. Clinical but not objective assessment of disease activity, anxiety, depression, female gender/sex, and younger age were also associated with more severe fatigue. Conclusions: Sleep quality and insomnia represent important modifiable contributors to fatigue. Future research should explore whether sleep interventions can improve fatigue in this population.

BACKGROUND: Ventral rectopexy has become increasingly used in the surgical management of rectal prolapse. There is a need for a contemporary evaluation of the role of the procedure and a description of its use in clinical practice. OBJECTIVE: To create an international consensus on ventral rectopexy. DESIGN: An expert panel undertook a scoping review of the literature to identify subject domains of interest. Literature reviews were completed for each domain with subsequent development of evidence-based and practice-based statements. These statements were compiled and reviewed by the group over a total of 9 meetings. Once statements were confirmed, supportive text was finalized, and an anonymous vote was completed using Research Electronic Data Capture to record consensus. SETTING: An international expert panel comprising colorectal surgeons who perform ventral rectopexy in a high-volume center. MAIN OUTCOME MEASURES: Statements and associated expert consensus. RESULTS: Eleven experts identified 10 domains for review: indications, contraindications, assessment and planning, consent, operative details, prostheses, complications, follow-up, recurrence and reoperative surgery, and specific considerations. After round table review, there were 17 resultant statements for consideration. Experts agreed unanimously with 13 of the statements and their accompanying text, with different experts disagreeing regarding the remaining 4 statements (91% consensus each). LIMITATIONS: Paucity of high-quality data. CONCLUSIONS: This international group developed 17 statements with high consensus. These statements provide an up-to-date summary of the literature, identify key areas for research development, and provide a reference point for colon and rectal surgeons who undertake ventral rectopexy as part of their practice.

Abstract Introduction Penile prosthesis (PP) is one of the main approved therapies for erectile dysfunction (ED). Greater than 50 years of clinical use has led to considerable innovation in PP surgery and patient care. Objectives To summarize the current literature and provide updated clinical evidence to inform healthcare providers on best practices with PP. Methods A consensus panel was held with leading sexual medicine experts during the 5th International Consultation on Sexual Medicine (ICSM). Relevant peer-reviewed literature was reviewed with focus on research from but not limited to the last 10 years. The quality of each individual study was judged with Oxford levels of evidence (LOE) criteria, but overall LOE were not used as systematic review was not performed. The expert panel generated consensus statements based on the quality of evidence and criteria of GRADE (Grading of Recommendations Assessment, Development and Evaluation). Results PP provides excellent outcomes for the treatment of ED. The panel developed 35 recommendations building upon previous recommendations. Nine recommendations (4, 5, 11,13,17, 25, 26, 31, and 32) are retained without change from 2015. Twelve recommendations (1, 2, 3, 7, 9,14,16,19,21, 28, 33, and 34) change syntax to make statements more active or change details. Fourteen recommendations (6, 8, 10, 12, 15, 18, 20, 22, 23, 24, 27, 29, 30, and 35) are novel in this update. Conclusion Since the 4th ICSM, new evidence has emerged to guide PP use in modern sexual medicine. While multi-institutional studies are needed to improve outcomes, key challenges remain: reducing infections, enhancing devices, and improving awareness and accessibility. We recommend following 5th ICSM guidelines while emphasizing the importance of clinical judgment and shared decision-making for optimal PP outcomes.

AbstractBackgroundExternal‐beam radiation (EBRT) is a noninvasive therapeutic alternative to transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). The objective of this study was to conduct a systematic review and meta‐analysis of prospective randomized clinical trials to assess the clinical efficacy of EBRT versus TACE for HCC as either a definitive monotherapy or as a bridge to transplantation/surgery.MethodsA systematic review and meta‐analysis were performed to include prospective randomized trials comparing EBRT versus TACE. Data was analyzed with random and fixed‐effects models. The inconsistency index (I2) was chosen to assess heterogeneity. Three publications were included with a total of 142 patients. Outcomes included local control (LC), overall survival (OS), progression‐free survival (PFS), and occurrences of grade ≥3 toxicity. Comparisons are reported as hazard ratios (HRs) or risk ratios (RRs) with 95% confidence intervals (CIs).ResultsThere were three randomized trials that met inclusion criteria. The EBRT was delivered in three to 15 fractions with a total dose between 30 and 75 gray(Gy). EBRT was associated with significantly improved LC (HR, 0.16; 95% CI, 0.08–0.34; I2 = 0%) and PFS (HR, 0.37; 95% CI, 0.23–0.60; I2, 0%) compared with TACE. There was no significant difference between EBRT and TACE in OS (RR, 0.79; 95% CI, 0.51–1.22; I2 = 0%) or grade ≥3 toxicity (RR, 0.86; 95% CI, 0.31–2.37; I2 = 57%). None of the analyses had statistically significant heterogeneity.ConclusionsCompared with TACE, EBRT yields superior LC and PFS without providing a survival benefit in early and intermediate stage HCC. Additional larger prospective randomized controlled trials should be conducted to further investigate differences in clinical outcomes amongst patients with more advanced disease.

AbstractIntroductionClinicopathological correlations differ by sex in Lewy body dementia (LBD). However, previous studies have focused on pathological staging systems that place less emphasis on regional pathologies.MethodsWe included 357 people (131 female, 226 male) with a high likelihood of LBD based on pathology from the Brain Bank for Neurodegenerative (Jacksonville, FL). Sex differences for regional Lewy body, senile plaque, and neurofibrillary tangle counts and their associations with clinical LBD diagnosis were assessed.ResultsFemales were less likely to have a clinical LBD diagnosis; they had more Lewy bodies, neurofibrillary tangles, and senile plaques in various regions than males (all p’s < 0.05). A higher likelihood of clinical LBD diagnosis was associated with more middle frontal, cingulate, and entorhinal Lewy body pathology, and more so for males than for females (all p’s < 0.045).DiscussionSex differences for clinicopathological correlations in LBD also occur at the regional pathology level. Females have a higher frequency of clinical misdiagnosis than males.Highlights Females have a higher risk of clinical underdiagnosis for Lewy body dementia (LBD) than males. Regional pathology counts differ by sex for people with a high likelihood of LBD. Regional pathology association with clinical LBD diagnosis differs by sex. Regional Lewy body counts have a stronger association with LBD phenotype for males.

AbstractINTRODUCTIONPlasma amyloid beta42/amyloid beta40 (Aβ42/Aβ40) and phosphorylated tau217 (p‐tau217) identify individuals with primary Alzheimer's disease (AD). They may detect AD co‐pathology in the setting of other primary neurodegenerative diseases, but this has not been systematically studied.METHODSWe compared the clinical, neuroimaging, and neuropathological associations of plasma Aβ42/Aβ40 (mass spectrometry), p‐tau217 (electrochemiluminescence), and neurofilament light ([NfL], single molecule array [Simoa]), as markers of AD co‐pathology, in a sporadic frontotemporal dementia (FTD) cohort (n = 620).RESULTSAβ42/Aβ40 showed no clinicopathological associations. High p‐tau217 was present in amnestic dementia (AmD) presumed to be due to FTD, logopenic primary progressive aphasia (lvPPA), and APOEε4 carriers, and correlated with worse baseline and longitudinal clinical scores, lower hippocampal volumes, and more severe AD co‐pathology (Braak Stage). NfL was elevated in all FTD phenotypes, and correlated with clinical scores and frontotemporal brain volumes.DISCUSSIONPlasma p‐tau217 has clinical, neuroimaging, and neuropathological correlates in sporadic FTD and may identify FTD cases with AD co‐pathology.Highlights Alzheimer's disease (AD) features could be identified with plasma phosphorylated tau217 (p‐tau217) in frontotemporal lobar degeneration (FTLD). Plasma p‐tau217 is a better discriminator of AD co‐pathology and AD‐associated features in FTLD than plasma amyloid beta42/amyloid beta40 (Aβ42/Aβ40) and neurofilament light (NfL). In FTLD, plasma p‐tau217, but not Aβ42/Aβ40 or neurofilament light, has phenotypical, neurocognitive, and neuroimaging correlates suggestive of AD co‐pathology.

Abstract Cerebrovascular inflammation is prevalent in a majority of Alzheimer’s patients. Inflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha), circulating in the plasma have been shown to cause the inflammation of blood-brain barrier (BBB) endothelium lining the cerebral microvasculature. The BBB inflammation has been implicated in the increase of toxic Aβ accumulation within Alzheimer’s disease (AD) brain. TNF-alpha in the peripheral circulation can aggravate the accumulation of amyloid-beta (Aβ) peptides in Alzheimer’s disease brain. In the current study, we have shown that the exposure to TNF-alpha leads to an increase in Aβ42 accumulation in mice and BBB endothelial cells in vitro. Moreover, dynamic SPECT/CT imaging in wild-type (WT) mice infused with TNF-alpha increased the permeability and influx of Aβ42 into the mice brain. In addition, our results show that TNF-alpha modifies the expression of cofilin, actin, and dynamin, which are critical components for Aβ endocytosis by BBB endothelial cells. These results offer a mechanistic understanding of how TNF-alpha may promote Aβ accumulation at the BBB and the underlying interactions between inflammation and Aβ exposure that drives BBB dysfunction. Hence, a therapeutic intervention aimed at addressing cerebrovascular inflammation in Alzheimer’s disease may potentially reduce Aβ induced cerebrovascular toxicity in Alzheimer’s disease brain. Significance statement Increased levels of TNF-alpha circulating in the plasma are considered significant factors in the consequences of Aβ pathology in Alzheimer’s disease, where it can promote cerebrovascular inflammation and BBB dysfunction. However, the role of TNF-alpha, in exacerbating Aβ pathology by increasing Aβ accumulation at the BBB endothelial cells remains only partially understood. In this study, we demonstrated that TNF-alpha enhances Aβ42 accumulation in the BBB endothelium by altering the expression of the BBB endocytosis machinery, specifically cofilin, actin, and dynamin. These findings are anticipated to contribute to the development of therapeutic approaches aimed at addressing elevated cytokine levels in Alzheimer’s disease. Graphical Abstract
