RESUMO
It is critical to address hepatitis C virus (HCV) in carceral settings to achieve worldwide elimination of the virus. We describe New Mexico's (NM) experience expanding HCV treatment in state prisons, supplemented with Project ECHO (ECHO; virtual mentorship through guided practice) and the NM Peer Education Program (NMPEP). We describe how using these programs may be a model for expanding treatment in prisons globally. ECHO, NM Corrections Department (NMCD) and Wexford Health Services (WHS) collaborate to treat HCV in state prisons and increase HCV knowledge among incarcerated persons using NMPEP. Each person arriving in prison is tested for HCV and those with active infection receive baseline labs, which are reviewed. Patients not meeting criteria for simplified treatment are presented to ECHO for expert guidance. Otherwise, patients are treated by WHS without consultation. NMPEP provides patient-to-patient education in prisons, addressing HCV myths and exploring treatment refusals. From December 2020 to June 2023, 3603 people had HCV viremia. In this study, 1685 people started treatment: 1280 were treated using the simplified algorithm and 405 were presented to ECHO. Of the 988 people who completed treatment and had sustained virologic response (SVR) labs drawn, 89.2% achieved SVR (i.e., cure). Most of the 107 people who did not achieve SVR had presumed reinfection. NMPEP trained 148 peer educators who educated 3832 peers about HCV prevention and treatment. HCV treatment in prisons can be expanded by implementing simplified treatment algorithms, use of the ECHO model for patients with advanced disease and peer education.
RESUMO
BACKGROUND: Little is known about global practices regarding the provision of reimbursement for the participation of people who are incarcerated in research. To determine current practices related to the reimbursement of incarcerated populations for research, we aimed to describe international variations in practice across countries and carceral environments to help inform the development of more consistent and equitable practices. METHODS: We conducted a scoping review by searching PubMed, Cochrane library, Medline, and Embase, and conducted a grey literature search for English- and French-language articles published until September 30, 2022. All studies evaluating any carceral-based research were included if recruitment of incarcerated participants occurred inside any non-juvenile carceral setting; we excluded studies if recruitment occurred exclusively following release. Where studies failed to indicate the presence or absence of reimbursement, we assumed none was provided. RESULTS: A total of 4,328 unique articles were identified, 2,765 were eligible for full text review, and 426 were included. Of these, 295 (69%) did not offer reimbursement to incarcerated individuals. A minority (n = 13; 4%) included reasons explaining the absence of reimbursement, primarily government-level policies (n = 7). Among the 131 (31%) studies that provided reimbursement, the most common form was monetary compensation (n = 122; 93%); five studies (4%) offered possible reduced sentencing. Reimbursement ranged between $3-610 USD in total and 14 studies (11%) explained the reason behind the reimbursements, primarily researchers' discretion (n = 9). CONCLUSIONS: The majority of research conducted to date in carceral settings globally has not reimbursed incarcerated participants. Increased transparency regarding reimbursement (or lack thereof) is needed as part of all carceral research and advocacy efforts are required to change policies prohibiting reimbursement of incarcerated individuals. Future work is needed to co-create international standards for the equitable reimbursement of incarcerated populations in research, incorporating the voices of people with lived and living experience of incarceration.

PURPOSE: Unaddressed hearing loss can adversely affect employment and day-to-day work-life. Efficient and effective audiology support can help optimise hearing in the workplace. This study explores the audiological rehabilitation experiences of workers with hearing loss (WHL). MATERIALS AND METHODS: Twenty-four WHL with experience of a wide range of audiology services across the UK participated in semi-structured interviews. Interviews were analysed using inductive thematic analysis. RESULTS: Three main themes were generated: Theme 1: mixed experiences with audiology services (subdivided into two subthemes and four sub-subthemes). Theme 2: audiology role in work support (subdivided into three subthemes). Theme 3: "I think support could be improved if " (subdivided into two subthemes). CONCLUSION: The audiological rehabilitation for working-age adults with hearing loss needs improvements to deliver sufficient support and quality care. Some of the barriers to having better-functioning hearing healthcare require fundamental standards in healthcare quality, such as access to services, staff (including audiologists) deaf awareness, information and technology support, and personalised care that considers work-life needs. Further research is required to evaluate the feasibility and cost-effectiveness of improvements, such as support that extends beyond hearing aid care, whether from audiology or non-audiology services.
Workers with hearing loss need audiologists' support to address their work life needs beyond hearing-aids care.Improving audiologists' competencies, audiology departments' efficiency and developing relevant resources may promote better healthcare for workers with hearing loss.Audiologists, employers, workers, and the healthcare system need to collaborate in developing person-centred solutions to sufficiently assist workers with hearing loss.
RESUMO
Objective: The goal is to implement the developed speech material in a hearing test to assess auditory fitness for duty (AFFD), specifically in areas where the intelligibility of spoken commands is essential. Design: In study 1, a speech corpus with equal intelligibility was constructed using constant stimuli to test each target word's psychometric functions. Study 2 used an adaptive interleaving procedure to maximize equalized terms. Study 3 used Monte Carlo simulations to determine speech test accuracy. Study sample: Study 1 (n = 24) and study 2 (n = 20) were completed by civilians with normal hearing. Study 3 ran 10,000 simulations per condition across various conditions varying in slopes and speech recognition thresholds (SRTs). Results: Studies 1 and 2 produced three 8-word wordlists. The mean, standard deviation in dB SNR is -13.1 1.2 for wordlist 1, -13.7 1.6 for wordlist 2, and -13.7 1.3 for wordlist 3, with word SRTs within 3.4 dB SNR. Study 3 revealed that a 6 dB SNR range is appropriate for equally understandable speech using a closed-set adaptive technique. Conclusion: The developed speech corpus may be used in an AFFD measure. Concerning the homogeneity of the speech in noise test material, care should be taken when generalizing and using ranges and standard deviations from multiple tests.

Diagnosis of Wilson disease (WD) can be difficult because of its protean clinical presentations, but early diagnosis is important because effective treatment is available and can prevent disease progression. Similarly, diagnosis of WD on liver biopsy specimens is difficult due to the wide range of histologic appearances. A stain that could help identify WD patients would be of great value. The goal of this study was to use mass spectrometry-based proteomics to identify potential proteins that are differentially expressed in WD compared to controls, and could serve as potential immunohistochemical markers for screening. Several proteins were differentially expressed in WD and immunohistochemical stains for two (metallothionein (MT) and cytochrome C oxidase copper chaperone (COX17)) were tested and compared to other methods of diagnosis in WD including copper staining and quantitative copper assays. We found diffuse metallothionein immunoreactivity in all liver specimens from patients with WD (n = 20); the intensity of the staining was moderate to strong. This staining pattern was distinct from that seen in specimens from the control groups (none of which showed strong, diffuse staining), which included diseases that may be in the clinical or histologic differential of WD (steatohepatitis (n = 51), chronic viral hepatitis (n = 40), autoimmune hepatitis (n = 50), chronic biliary tract disease (n = 42), and normal liver (n = 20)). COX17 immunostain showed no significant difference in expression between the WD and control groups. MT had higher sensitivity than rhodanine for diagnosis of WD. While the quantitative liver copper assays also had high sensitivity, they require more tissue, have a higher cost, longer turnaround time, and are less widely available than an immunohistochemical stain. We conclude that MT IHC is a sensitive immunohistochemical stain for the diagnosis of WD that could be widely deployed as a screening tool for liver biopsies in which WD is in the clinical or histologic differential diagnosis.

PURPOSE: This study explored audiologists' perspectives regarding their interactions with workers with hearing loss (WHL). MATERIALS AND METHODS: Semi-structured interviews were conducted with twenty-five audiologists working in the National Health Service (NHS) and independent companies (IC) in the UK and were thematically analysed. RESULTS: The developed themes and sub-themes (shown in parenthesis) are (1) Current practices and routines (Same approach for most patients; Variations between hearing care services; Audiologists' personal experience of hearing loss) (2) Perceived challenges (Non-routine and challenging cases; The role of hearing technology; Concerns about lack of awareness and knowledge; Communication difficulties between services, Limited funding and resources) (3) Scope for better support (Would like to be informed; Other potential service improvements). CONCLUSIONS: This study revealed that audiologists' perceived deficiencies in the hearing rehabilitation for WHL and identified ways to improve it. Key priorities for improvement were found to include addressing audiologists' informational and training needs, facilitating WHLs' access to appointments, improving communication between services, raising awareness in the workplace, developing relevant resources and extending funding for provision of longer appointments and hearing technologies. This is the first time this information has been reported in the literature. Opportunities for conducting further research in this area are suggested.Implications for rehabilitationWorkers with hearing loss face many challenges in work life and have the option of audiologic rehabilitation to alleviate their difficulties and improve their wellbeing; however, this study suggests that workers' audiological care needs improvements.Audiologists should assess and consider patients' work needs and psychosocial concerns in consultations to provide personalised care.Audiology educational programmes, services, and the healthcare system can assist audiologists in helping workers with hearing loss by providing updated knowledge, continuous training and improved interprofessional communication and patients' access to useful resources.

Myxoid hepatic adenomas are a rare subtype of hepatic adenomas with distinctive deposition of extracellular myxoid material between the hepatic plates. A total of 9 cases were identified in 6 women and 3 men with an average of 59±12 years. The myxoid adenomas were single tumors in 5 cases and multiple in 4 cases. In 1 case with multiple adenomas, the myxoid adenoma arose in the background of GNAS-mutated hepatic adenomatosis. Myxoid hepatic adenomas had a high frequency of malignant transformation (N=5 cases). They were characterized at the molecular level by HNF1A inactivating mutations, leading to loss of LFABP protein expression. In addition, myxoid adenomas had recurrent mutations in genes within the protein kinase A (PKA) pathway or in genes that regulate the PKA pathway: GNAS, CDKN1B (encodes p27), and RNF123. In sum, myxoid adenomas are rare, occur in older-aged persons, have a high risk of malignant transformation, and are characterized by the combined inactivation of HNF1A and additional mutations that appear to cluster in the PKA pathway.

BACKGROUND: Endoscopic resection (ER) is an emerging therapeutic alternative for subepithelial gastrointestinal lesions (SELs). We aimed to determine whether size, layer of origin, and histology based on endoscopic ultrasound (EUS) and EUS-guided sampling (EUS-GS) influenced the outcomes and selection of patients for ER. METHODS: We performed a retrospective review of patients who underwent EUS, EUS-GS and resection of SELs from 2012-2019. Two pathologists reviewed the histology and layer of origin of all resected specimens, serving as the criterion for EUS accuracy. RESULTS: Seventy-three patients were included, of whom 59 (81%) were gastric SELs. Per EUS, median lesion size was 21 mm (interquartile range 15-32), and 63 (86%) originated from the 4th layer. The overall accuracy of EUS and EUS-GS in predicting the layer of origin and histology was 88% (95% confidence interval [CI] 77-94%) and 96% (95%CI 87-98%), respectively. Based on EUS, 18 (25%) patients were referred for ER, 5 (7%) to laparoscopic-endoscopic cooperative surgery, and 50 (68%) to surgery. Size >20 mm was associated with the type of resection approach (P=0.005), while layer of origin and histology were not (P=0.06 and P=0.09, respectively). When SELs were inaccurately classified (n=4) there were no adverse events or revision of the resection approach. CONCLUSIONS: EUS plays an important role in the outcome of resection approach for SELs, with size significantly influencing the selection for ER. In patients undergoing ER, no revised resections were needed when EUS was inaccurate.
RESUMO
AIMS: The diagnosis of focal nodular hyperplasia (FNH) and the interpretation of glutamine synthetase (GS) staining can be challenging on biopsies. We aimed to evaluate the reproducibility of needle biopsy diagnosis of FNH, the effect of GS immunohistochemistry on FNH diagnosis, and which histological features are most useful for the diagnosis of FNH. METHODS AND RESULTS: The study included virtual needle biopsies generated from 75 resection specimens (30 FNHs, 15 hepatocellular adenomas, 15 hepatocellular carcinomas, and 15 non-lesional liver specimens). Pathologists were reasonably accurate (83.1%) in the diagnosis of FNH with haematoxylin and eosin alone. Ductular reaction and nodularity had the highest sensitivity for a diagnosis of FNH (88.1% and 82.2%, respectively), whereas central scar was the most specific feature (90.6%). The presence of two or more of the classic histological features had 89.6% sensitivity and 86.2% specificity for a diagnosis of FNH. Diagnostic accuracy was significantly higher with the addition of a GS stain. A map-like GS staining pattern was highly specific (99.3%) for FNH. However, GS staining was interpreted as non-map-like in 14.4% of reviews of true FNH cases, and overall interobserver agreement for interpretation of the GS staining pattern was only moderate (kappa = 0.42). CONCLUSIONS: Pathologists are reasonably accurate in the diagnosis of FNH on virtual biopsies, and GS staining improves accuracy. However, a subset of FNH cases remain challenging. Steatosis and a pseudo-map-like GS staining pattern were associated with increased difficulty. Therefore, although a map-like GS staining pattern is useful for confirmation of a diagnosis, the lack of a map-like GS staining pattern on needle biopsy does not necessarily exclude a diagnosis of FNH.

Pancreatic heterotopia most commonly occurs in the upper gastrointestinal tract, but can occur in other sites, including Meckel's diverticulum. When multiple histologic elements of the pancreatic tissue (acini, ducts, and endocrine cells) are present, the diagnosis is typically straightforward. In this article, we report a rare case of pure endocrine pancreatic heterotopia involving a Meckel's diverticulum, a potential mimic of a well-differentiated neuroendocrine tumor. Several features were useful in making the distinction, including lack of desmoplasia and mass forming lesion, and immunohistochemical staining in a physiological pattern similar to that of islets of Langerhans. It is important for pathologists to be aware of this entity and its features to avoid misdiagnosis of a neuroendocrine tumor.

GOALS: We aimed to describe the diagnostic and prognostic performance of transient elastography (TE) and magnetic resonance elastography (MRE) in patients with primary biliary cholangitis (PBC). BACKGROUND: The diagnostic performance of TE and MRE in detecting advanced fibrosis in PBC and in predicting outcomes independent of existing serologic prognostic markers is incompletely understood. MATERIALS AND METHODS: Five hundred thirty-eight consecutive patients with PBC at 3 centers with liver stiffness (LS) measurements by TE (n=286) or MRE (n=332) were reviewed. LS cutoffs for predicting fibrosis stages were determined by receiver operating characteristic curves among those with a liver biopsy (TE, n=63; MRE, n=98). Cox proportional hazard regression modeling was used to identify associations between covariates and hepatic decompensation. RESULTS: The optimal LS thresholds for predicting histologic stage F4 were 14.40 kPa (area under the curve=0.94) for TE and 4.60 kPa (area under the curve=0.82) for MRE. Both TE and MRE outperformed biochemical markers for the prediction of histologic advanced fibrosis. Optimal LS thresholds to predict hepatic decompensation were 10.20 kPa on TE and 4.30 kPa on MRE. LS by TE and MRE (respectively) remained predictors of hepatic decompensation after adjusting for ursodeoxycholic acid responsiveness [hazard ratio (HR), 1.14; 95% confidence interval (CI), 1.05-1.24 and HR, 1.68; 95% CI, 1.28-2.19] and the GLOBE score (HR, 1.13; 95% CI, 1.07-1.19 and HR, 2.09; 95% CI, 1.57-2.78). CONCLUSION: LS measurement with either TE or MRE can accurately detect advanced fibrosis and offers additional prognostic value beyond existing serologic predictive tools.

Intracholecystic neoplasms (ICNs) (pyloric gland adenomas and intracholecystic papillary neoplasms, collectively also called intracholecystic papillary/tubular neoplasms) form multifocal, extensive proliferations on the gallbladder mucosa and have a high propensity for invasion (>50%). In this study, 19 examples of a poorly characterized phenomenon, mural papillary mucinous lesions that arise in adenomyomatous nodules and form localized ICNs, were analyzed. Two of these were identified in 1750 consecutive cholecystectomies reviewed specifically for this purpose, placing its incidence at 0.1%. Median age was 68 years. Unlike other gallbladder lesions, these were slightly more common in men (female/male=0.8), and 55% had documented cholelithiasis. All were characterized by a compact multilocular, demarcated, cystic lesion with papillary proliferations and mucinous epithelial lining. The lesions' architecture, distribution, location, and typical size were suggestive of evolution from an underlying adenomyomatous nodule. All had gastric/endocervical-like mucinous epithelium, but 5 also had a focal intestinal-like epithelium. Cytologic atypia was graded as 1 to 3 and defined as 1A: mucinous, without cytoarchitectural atypia (n=3), 1B: mild (n=7), 2: moderate (n=2), and 3: severe atypia (n=7, 3 of which also had invasive carcinoma, 16%). Background gallbladder mucosal involvement was absent in all but 2 cases, both of which had multifocal papillary mucosal nodules. In conclusion, these cases highlight a distinct clinicopathologic entity, that is, mural ICNs arising in adenomyomatous nodules, which, by essentially sparing the "main" mucosa, not displaying "field-effect/defect" phenomenon, and only rarely (16%) showing carcinomatous transformation, are analogous to pancreatic branch duct intraductal papillary mucinous neoplasms.

Secreted Protein Acid and Rich in Cysteine (SPARC) is an extracellular glycoprotein secreted by fibroblasts and osteoblasts in normal tissues. SPARC overexpression occurs in multiple tumors including pancreatic ductal adenocarcinoma (PDAC) and may predict favorable response to nab-paclitaxel. The prognostic significance of SPARC expression in PDAC is unclear - some reports indicate SPARC overexpression associates with poor outcomes and others find no correlation. Considering neoadjuvant therapy enhances the stromal fibrosis of PDAC and taking into account that SPARC is a component of PDAC stromal fibrosis, we hypothesized that SPARC expression would be greater in neoadjuvant-treated versus treatment-naive PDAC. Quantitative immunohistochemistry was used to measure SPARC expression in resected PDAC in 74 cases of neoadjuvant treated PDAC and 95 cases of treatment-naïve PDAC. SPARC expression was increased 54% in neoadjuvant treated PDAC compared to treatment-naïve PDAC. These data indicate that increased SPARC expression correlates with neoadjuvant therapy in PDAC.

The 8th edition AJCC T stage criteria for pancreatic ductal adenocarcinoma (PDAC) are now size based. These criteria provide better prognostic stratification in patients without neoadjuvant therapy. Our aim was to determine if gross tumor size is prognostically significant using the 8th ed. staging criteria for neoadjuvant treated PDAC. The study included 289 patients who underwent resection for PDAC following neoadjuvant therapy. By AJCC 7th ed., there were 12 (4.2%) ypT0, 32 (11.1%) ypT1, 64 (22.1%) ypT2, and 181 (62.6%) ypT3 patients. By AJCC 8th ed., there were 12 (4.2%) ypT0, 74 (25.6%) ypT1 (6 ypT1a, 1 ypT1b, 67 ypT1c), 161 (55.7%) ypT2, and 42 (14.5%) ypT3 patients. 182 patients had negative lymph nodes and 107 had positive lymph nodes. 77 patients were ypN1 and 30 were ypN2 by 8th ed. criteria. 7th ed. T stage significantly correlated with OS (p = 0.048), while 8th ed. T stage did not correlate with OS (p = 0.13). In ypN0 patients, neither the 7th ed. or 8th ed. T stages significantly correlated with patient OS (p = 0.065 and 0.26, respectively). Higher 7th ed. T stage correlated with lymph node status (p ≤ 0.001) more strongly than 8th ed. T stage (p = 0.04). 7th ed. and 8th ed. N stage correlated with OS (p = 0.004 and p = 0.0002, respectively). By 8th ed. AJCC staging criteria, gross tumor size does not provide good prognostic stratification in neoadjuvant therapy PDAC. Mapped grossing techniques combining gross and microscopic examination to determine tumor size may provide more accurate staging of neoadjuvant treated tumors.

It is not well understood whether background speech affects the initial processing of words during reading or only the later processes of sentence integration. Additionally, it is not clear how eye movements support text comprehension in the face of distraction by background speech and noise. In the present research, participants read single sentences (Experiment 1) and short paragraphs (Experiments 2-3) in 4 sound conditions: silence, speech-spectrum Gaussian noise, English speech (intelligible to participants), and Mandarin speech (unintelligible to participants). Intelligible speech did not affect the lexical access of words and had a limited effect on the first-pass fixations of words. However, it led to more regressions and more rereading fixations compared with both unintelligible speech and silence. The results suggested that the distraction is mostly semantic in nature, and there was only limited evidence for a contribution of phonology. Finally, intelligible speech disrupted comprehension only when participants were prevented from rereading previous words. These findings suggest that the semantic properties of irrelevant speech can disrupt the ongoing reading process, but that this disruption occurs in the postlexical stages of reading when participants need to integrate words to form the sentence context and to construct a coherent discourse of the text.

Pancreatic serous cystadenoma (SCA) is a benign neoplastic lesion with a distinctive gross and microscopic appearance consisting of numerous thin-walled cysts lined by uniform epithelial cells with clear cytoplasm and small nuclei. The vast majority of serous cystadenomas are benign. Pancreatic SCA has rarely been reported in association with other pancreatic lesions. We present a challenging case in which a cystic and solid pancreatic mass was identified on imaging studies. FNA was performed and showed clusters of atypical cells with significant nuclear pleomorphism (>4:1), disorganized, overlapping nuclei, and prominent nucleoli. The FNA diagnosis was positive for malignancy, consistent with adenocarcinoma. The patient underwent neoadjuvant therapy and pancreaticoduodenectomy. Final pathology showed a serous cystadenoma associated with small foci of high-grade PanIN. The lack of invasive adenocarcinoma in the resection specimen was most likely due to complete response of the tumor to neoadjuvant chemoradiation therapy, but it is also possible that only high-grade PanIN was present initially. To our knowledge, this is the first reported case of SCA and high grade PanIN/PDAC that was assessed by FNA. We discuss the cytologic differential diagnosis and how to avoid potential pitfalls highlighted by this case.
