Abstract
Preoperative localization procedures are important for guiding surgical excision of non-palpable findings in the breast. The SCOUT Reflector (Merit Medical, South Jordan UT, USA) is a non-wire-based localization device that has been incorporated into clinical use with great success. SCOUT Reflectors can be placed using several imaging modalities, including tomosynthesis. One drawback to SCOUT Reflector placement under tomosynthesis guidance is an inability to directly visualize the introducer needle tip, a factor that limits precision. In this brief communication, we describe the use of a lateral arm attachment for tomosynthesis guided SCOUT Reflector placement. Precise SCOUT Reflector placement can be achieved using the lateral arm due to the ability to clearly visualize the introducer needle and the SCOUT Reflector within the introducer needle bore prior to deployment.

Abstract
Socio-ecological factors are major determinants of poor mental health across the life span. These factors can lead to health inequalities, which refer to differences in the health of individuals or groups (Kirkbride et al., 2024). Health inequity "is a specific type of health inequality that denotes an unjust, avoidable, systematic and unnecessary difference in health" (Arcaya, Arcaya, & Subramanian, 2015). Among several intersecting social adversities, inequity is one of the most pervasive contributors to poor mental health across all regions (Venkatapuram & Marmot, 2023). Structural inequity creates institutional power structures that marginalise large sections of the population and concentrate resources in the hands of a small minority (Shim, Kho, & Murray-García, 2018). The world is now more prosperous than it has ever been, yet the world is witnessing more within country inequality with the vast majority of the world's resources in the hands of a small minority of individuals or regions (United Nations, 2020).

Abstract
Recent decades have seen exponential growth in research on modifiable risk factors for dementia across the lifespan, which has considerably advanced our understanding of brain health. Not all modifiable risk factors are equal, however, in the ease with which they can be addressed. Some individuals and populations face significant barriers to engaging in dementia risk-reduction behaviors. With the evolution of the dementia prevention field, there is a need to broaden our approach from identifying individual risk factors toward addressing inclusive and globally effective intervention strategies. Here, we argue for a greater awareness of individual and socioeconomic barriers to behavior change-oriented dementia risk reduction. We caution against inadvertently increasing health inequities through "lifestyle" stigma and call for an approach that both harnesses current dementia risk-reduction knowledge and effectively addresses barriers to change. A greater focus on more positive aspects of reducing dementia risk, such as enhancing mental well-being, may also be beneficial. Evidence for the negative ramifications of stigma in dementia is discussed as well as overly simplistic media representations of dementia as a disease, which one can "stave off" through lifestyle. Further, we explore potential negative implications for research funding and policy resulting from stigma. More research regarding the experience of stigma in dementia is needed, across diverse cultural and socioeconomic groups.

Abstract
OBJECTIVE Maternal thrombocytopenia during pregnancy may occur due to several possible etiologies, with potential neonatal impact. The aim of the present study was to investigate whether there is a correlation between maternal and neonatal platelet count among women with thrombocytopenia during pregnancy. METHODS A cross-sectional retrospective study (2012-2019) was conducted at a tertiary medical center. Complete blood count was routinely measured in all patients on admission to the delivery ward. Thrombocytopenia was defined as a platelet count below 150 K/μL. Clinical and outcome parameters of thrombocytopenic mothers and their newborns were collected from the electronic files and analyzed by severity of maternal thrombocytopenia. RESULTS Of 45 385 women with a documented platelet count at admission, 2841 (6.24%) had thrombocytopenia: 2623 (5.7%) mild (100-149 K/μL), 207 (0.45%) moderate (50-99 K/μL), and 11 (0.02%) severe (<50 K/μL). Eight newborns had thrombocytopenia; corresponding rates by severity of maternal thrombocytopenia were 0.11%, 1.43%, and 18.18% (P = 0.04). None of the thrombocytopenic neonates had an intraventricular hemorrhage or other bleeding complications. The correlation between maternal and neonatal platelet counts was weak (Pearson r = 0.038; P = 0.046). CONCLUSION We suggest that although the chances of neonatal thrombocytopenia are higher with worsening maternal thrombocytopenia, actual occurrence is rare, and the correlation is poor. Therefore, maternal thrombocytopenia cannot be regarded as a significant risk factor for neonatal thrombocytopenia. Neonatal platelet count should be obtained when maternal thrombocytopenia is autoimmune or less than 100 K/μL.

Abstract
ABSTRACT In the peripheral nervous system, spontaneous activity in sensory neurons is considered to be one of the 2 main drivers of chronic pain states, alongside neuronal sensitization. Despite this, the precise nature and timing of this spontaneous activity in neuropathic pain is not well-established. Here, we have performed a systematic search and data extraction of existing electrophysiological literature to shed light on which fibre types have been shown to maintain spontaneous activity and over what time frame. We examined both in vivo recordings of preclinical models of neuropathic pain, as well as microneurography recordings in humans. Our analyses reveal that there is broad agreement on the presence of spontaneous activity in neuropathic pain conditions, even months after injury or years after onset of neuropathic symptoms in humans. However, because of the highly specialised nature of the electrophysiological methods used to measure spontaneous activity, there is also a high degree of variability and uncertainty around these results. Specifically, there are very few directly controlled experiments, with less directly comparable data between human and animals. Given that spontaneous peripheral neuron activity is considered to be a key mechanistic feature of chronic pain conditions, it may be beneficial to conduct further experiments in this space.

Abstract
OBJECTIVE Endometriosis affects up to 10% of reproductive age women and is associated with pelvic pain and subfertility. While previous studies have shown an association between deep and ovarian endometriosis to reduced ovarian reserve, there is no data on the effect of superficial endometriosis on ovarian reserve markers. Hence, we aimed to compare ovarian reserve markers of women with superficial endometriosis to that of women without endometriosis. METHODS This was a case control study in a tertiary medical center. The study group included women aged 18-40 with surgically and histopathology-proven superficial endometriosis with no deep lesions or ovarian involvement. The control group included women with no known or suspected endometriosis and was matched to the study group by age, BMI and parity. We excluded women with other known risk factors for ovarian failure and with other gynecological disorders. Participants completed a questionnaire with demographic, medical and gynecological data. Each patient underwent anti-Mullerian hormone (AMH) testing and an ultrasound to assess their antral follicular count (AFC). AMH and AFC were then compared between groups. RESULTS A total of 124 women participated in the study. Of these, 50% (n = 62) had surgically proven superficial endometriosis and 50% (n = 62) were without known or suspected endometriosis. Mean AMH levels of women with and without superficial endometriosis was 3.0 ± 2.8 ng/mL and 2.8 ± 1.9 ng/mL, respectively (P = 0.71). AFC also did not differ between groups (women with superficial endometriosis: 12.0 ± 6.6; women without endometriosis: 10.2 ± 5.0, P = 0.15). CONCLUSIONS In our cohort, superficial endometriosis was not associated with diminished ovarian reserve. While further studies are needed, to date, it does not appear to be justified to assess ovarian reserve for patients with superficial endometriosis.

Abstract
The purpose of this study was to explore the effects of combined lead (Pb) and two types of microplastic (MP) (polyvinyl chloride [PVC] and polyethylene [PE]) exposure on glucose metabolism and investigate the role of the nuclear factor erythroid 2-related factor 2 (Nrf2)/nuclear factor-kappa B (NF-κB) signaling pathway in mediating these effects in mice. Adult C57BL/6J mice were randomly divided into four groups: control, Pb (100 mg/L), MPs (containing 10 mg/L PE and PVC), and Pb + MPs, each of which was treated with drinking water. Treatments were conducted for 6 weeks. Co-exposure to Pb + MPs exhibited increase glycosylated serum protein levels, insulin resistance, and damaged glucose tolerance compared with the control mice. Additionally, treatment with Pb + MPs caused more severe damage to hepatocytes than when exposed to them alone concomitantly, exposed to Pb + MPs exhibited improved the levels of interleukin-6, tumor necrosis factor-alpha, and malondialdehyde, but reduced superoxide dismutase, glutathione peroxidase, and catalase assay in livers. Furthermore, they increase the Kelch-like ECH-associated protein 1 (Keap1) and phosphorylated p-NF-κB protein levels but reduced the protein levels of heme oxygenase-1 and Nrf2, as well as increased Keap1 mRNA and Nrf2 mRNA. Co-exposure to Pb + MP impacts glucose metabolism via the Nrf2 /NF-κB pathway.

Abstract
Thiacloprid (THI) is a neonicotinoid insecticide, and its wide-ranging use has contributed to severe environmental and health problems. Dendrobium officinale polysaccharide (DOP) possesses multiple biological activities such as antioxidant and antiapoptosis effect. Although present research has shown that THI causes kidney injury, the exact molecular mechanism and treatment of THI-induced kidney injury remain unclear. The study aimed to investigate if DOP could alleviate THI-induced kidney injury and identify the potential molecular mechanism in quails. In this study, Japanese quails received DOP (200 mg/kg) daily with or without THI (4 mg/kg) exposure for 42 days. Our results showed that DOP improved hematological changes, biochemical indexes, and nephric histopathological changes induced by THI. Meanwhile, THI exposure caused oxidative stress, apoptosis, and autophagy. Furthermore, THI and DOP cotreatment significantly activated the nuclear factor erythroid 2-related factor 2/heme oxygenase-1 (Nrf2/HO-1) pathway, restored antioxidant enzyme activity, and reduced apoptosis and autophagy in quail kidneys. In summary, our study demonstrated that DOP mitigated THI-mediated kidney injury was associated with oxidative stress, apoptosis, and autophagy via activation of the Nrf2/HO-1 signaling pathway in quails.

Abstract
BACKGROUND Gastric cancer (GC) is the third leading cause of cancer-related death worldwide, with a poor prognosis for patients with advanced disease. Since the oncogenic role of KRAS mutants has been poorly investigated in GC, this study aims to biochemically and biologically characterize different KRAS-mutated models and unravel differences among KRAS mutants in response to therapy. METHODS Taking advantage of a proprietary, molecularly annotated platform of more than 200 GC PDXs (patient-derived xenografts), we identified KRAS-mutated PDXs, from which primary cell lines were established. The different mutants were challenged with KRAS downstream inhibitors in in vitro and in vivo experiments. RESULTS Cells expressing the rare KRAS A146T mutant showed lower RAS-GTP levels compared to those bearing the canonical G12/13D mutations. Nevertheless, all the KRAS-mutated cells displayed KRAS addiction. Surprisingly, even if the GEF SOS1 is considered critical for the activation of KRAS A146T mutants, its abrogation did not significantly affect cell viability. From the pharmacologic point of view, Trametinib monotherapy was more effective in A146T than in G12D-mutated models, suggesting a vulnerability to MEK inhibition. However, in the presence of mutations in the PI3K pathway, more frequently co-occurrent in A146T models, the association of Trametinib and the AKT inhibitor MK-2206 was required to optimize the response. CONCLUSION A deeper genomic and biological characterization of KRAS mutants might sustain the development of more efficient and long-lasting therapeutic options for patients harbouring KRAS-driven GC.

Abstract
Cigarette smoking was known to accelerate the occurrence and development of bladder cancer by regulating RNA modification. However, the association between the combination of cigarette smoking and RNA modification-related single nucleotide polymorphisms (RNAm-SNPs) and bladder cancer risk remains unclear. In this study, 1681 participants, including 580 cases and 1101 controls, were recruited for genetic association analysis. In total, 1 287 990 RNAm-SNPs involving nine RNA modifications (m6A, m1A, m6Am, 2'-O-Me, m5C, m7G, A-to-I, m5U, and pseudouridine modification) were obtained from the RMVar database. The interactive effect of cigarette smoking and RNAm-SNPs on bladder cancer risk was assessed through joint analysis. The susceptibility analysis revealed that 89 RNAm-SNPs involving m6A, m1A, and A-to-I modifications were associated with bladder cancer risk. Among them, m6A-related rs2273058 in CRNKL1 was associated with bladder cancer risk (odds ratios (OR) = 1.35, padj = 1.78 × 10-4), and CRNKL1 expression was increased in bladder cancer patients (p = 0.035). Cigarette smoking combined with the A allele of rs2273058 increased bladder cancer risk compared with nonsmokers with the G allele of rs2273058 (OR = 2.40, padj = 3.11 × 10-9). Mechanistically, the A allele of rs2273058 endowed CRNKL1 with an additional m6A motif, facilitating recognition by m6A reader IGF2BP1, thereby promoting CRNKL1 expression under cigarette smoking (r = 0.142, p = 0.017). Moreover, elevated CRNKL1 expression may accelerate cell cycle and proliferation, thereby increasing bladder cancer risk. In summary, our study demonstrated that cigarette smoking combined with RNAm-SNPs contributes to bladder cancer risk, which provides a potential target for bladder cancer prevention.

Abstract
BACKGROUND Colorectal cancer (CRC) presents a significant global health burden, characterized by a heterogeneous molecular landscape and various genetic and epigenetic alterations. Programmed cell death (PCD) plays a critical role in CRC, offering potential targets for therapy by regulating cell elimination processes that can suppress tumor growth or trigger cancer cell resistance. Understanding the complex interplay between PCD mechanisms and CRC pathogenesis is crucial. This study aims to construct a PCD-related prognostic signature in CRC using machine learning integration, enhancing the precision of CRC prognosis prediction. METHOD We retrieved expression data and clinical information from the Cancer Genome Atlas and Gene Expression Omnibus (GEO) datasets. Fifteen forms of PCD were identified, and corresponding gene sets were compiled. Machine learning algorithms, including Lasso, Ridge, Enet, StepCox, survivalSVM, CoxBoost, SuperPC, plsRcox, random survival forest (RSF), and gradient boosting machine, were integrated for model construction. The models were validated using six GEO datasets, and the programmed cell death score (PCDS) was established. Further, the model's effectiveness was compared with 109 transcriptome-based CRC prognostic models. RESULT Our integrated model successfully identified differentially expressed PCD-related genes and stratified CRC samples into four subtypes with distinct prognostic implications. The optimal combination of machine learning models, RSF + Ridge, showed superior performance compared with traditional methods. The PCDS effectively stratified patients into high-risk and low-risk groups, with significant survival differences. Further analysis revealed the prognostic relevance of immune cell types and pathways associated with CRC subtypes. The model also identified hub genes and drug sensitivities relevant to CRC prognosis. CONCLUSION The current study highlights the potential of integrating machine learning models to enhance the prediction of CRC prognosis. The developed prognostic signature, which is related to PCD, holds promise for personalized and effective therapeutic interventions in CRC.

Abstract
OBJECTIVES There is a limited understanding of the impact of cochlear implantation (CI) in patients with Charcot-Marie-Tooth disease (CMT), given the scarcity of reported cases. We aim to evaluate the audiological outcomes and quality of life (QoL) after CI in CMT. METHODS Multi-institutional, university-affiliated, tertiary-referral centers, retrospective chart review.Our cohort includes 5 patients with CMT. Patients' charts were reviewed for demographic characteristics, operation notes, and pre- and post-implantation audiology evaluation. Patients completed the Cochlear Implant Quality of Life-10 (CIQOL-10) Global questionnaire. RESULTS Pre-implantation, the mean pure tone average was 84.1 ± 7.2 dB, and the mean word recognition score was 2.4% in the implanted ear. AzBio sentence test was performed in quiet, revealing a mean of 4 ± 1.4% in the implanted ear. Post-implantation, PTA results were all within the mild hearing loss range (mean 33.0 ± 5.9 dB). Post-CI, AZ-Bio test results were 5%, 65%, and 74% (for 3 patients), and HINT scores were 55% and 58% (for 2 patients). The mean score of the CIQOL-10 questionnaire was 42.7 ± 10.47 (range 1-100). Patients were most satisfied with their ability to listen to the television or radio, have conversations in a quiet environment, and feel comfortable being themselves. CONCLUSION To the best of our knowledge, this is the most extensive series of CI in CMT-associated sensorineural hearing loss and auditory neuropathy. Our cohort suggests that CI is a safe and reliable method for hearing rehabilitation that can achieve good speech performance and improve QoL in CMT patients.

Abstract
AIMS This qualitative study aimed to develop the first cognitive behavioural (CBT) model outlining the development and maintenance of disordered eating in adult men living with Type 1 diabetes to improve on previous theoretical models of Type 1 diabetes and disordered eating and to draw comparisons to women with Type 1 diabetes and disordered eating. METHODS Twenty-seven men (n = 16 with Type 1 diabetes and disordered eating, n = 11 with Type 1 diabetes without disordered eating) participated in semi-structured interviews. Data were analysed using thematic analysis and individual CBT formulations were developed for each participant to inform the model. RESULTS Men with Type 1 diabetes and disordered eating experience negative thoughts about food, insulin, weight/shape and diabetes itself, which cause negative emotions such as fear and vulnerability and difficulties with diabetes self care such as problems with hyper and hypoglycaemia and problems accessing structured education and technology result in men feeling more dissatisfied about their body weight/shape. CONCLUSIONS This CBT model of disordered eating in men with Type 1 diabetes can guide new interventions.

Abstract
Aging and age-related diseases are associated with cellular stress, metabolic imbalance, oxidative stress, and neuroinflammation, accompanied by cognitive impairment. Lifestyle factors such as diet, sleep fragmentation, and stress can potentiate damaging cellular cascades and lead to an acceleration of brain aging and cognitive impairment. High-fat diet (HFD) has been associated with obesity, metabolic disorders like diabetes, and cardiovascular disease. HFD also induces neuroinflammation, impairs learning and memory, and may increase anxiety-like behavior. Effects of a HFD may also vary between sexes. The interaction between Age- and Sex- and Diet-related changes in neuroinflammation and cognitive function is an important and poorly understood area of research. This study was designed to examine the effects of HFD on neuroinflammation, behavior, and neurodegeneration in mice in the context of aging or sex differences. In a series of studies, young (2-3 months) or old (12-13 months) C57BL/6J male mice or young male and female C57Bl/6J mice were fed either a standard diet (SD) or a HFD for 5-6 months. Behavior was assessed in Activity Chamber, Y-maze, Novel Place Recognition, Novel Object Recognition, Elevated Plus Maze, Open Field, Morris Water Maze, and Fear Conditioning. Post-mortem analyses assessed a panel of inflammatory markers in the plasma and hippocampus. Additionally, proteomic analysis of the hypothalamus, neurodegeneration, neuroinflammation in the locus coeruleus, and neuroinflammation in the hippocampus were assessed in a subset of young and aged male mice. We show that HFD increased body weight and decreased locomotor activity across groups compared to control mice fed a SD. HFD altered anxiety-related exploratory behavior. HFD impaired spatial learning and recall in young male mice and impaired recall in cued fear conditioning in young and aged male mice, with no effects on spatial learning or fear conditioning in young female mice. Effects of Age and Sex were observed on neuroinflammatory cytokines, with only limited effects of HFD. HFD had a more significant impact on systemic inflammation in plasma across age and sex. Aged male mice had induction of microglial immunoreactivity in both the locus coeruleus (LC) and hippocampus an effect that HFD exacerbated in the hippocampal CA1 region. Proteomic analysis of the hypothalamus revealed changes in pathways related to metabolism and neurodegeneration with both aging and HFD in male mice. Our findings suggest that HFD induces widespread systemic inflammation and limited neuroinflammation. In addition, HFD alters exploratory behavior in male and female mice, and impairs learning and memory in male mice. These results provide valuable insight into the impact of diet on cognition and aging pathophysiology.

Abstract
In Greece, 5G New Radio (NR) has started launching in the end of 2020, at the 3400-3800 MHz (FR1) frequency band. Focusing on 117 Base Stations (BSs) which were already equipped with 5G NR antennas, in situ broadband and frequency selective measurements have been conducted at minimum three points of interest, at adjacent rooftops (when accessible). The points have been selected according to the sweeping method and the electric field strength (E) value has been stored on the selected worst-case scenario point. Spectrum analysis was conducted in the FR1, for the allocated spectrum that corresponds to each mobile communication provider, in order to get preliminary results concerning the contribution of the 5G NR emissions in the general public exposure levels. The vast majority of the in situ measurements has been conducted in urban environments from the beginning of 2021 until the mid of 2022, since in Greece 5G NR services launching started from the big cities. Additionally, a 5G NR BS, installed in a suburban environment (in the city of Kalamata) is thoroughly investigated during its pilot and regular operation, based on broadband and frequency selective measurements data derived by the National Observatory of Electromagnetic Fields (NOEF) monitoring sensor network. In situ measurement data within the 5G NR frequency range are verified via the NOEF's output. The 5G NR contribution to the total E-field levels is assessed in time, from pilot to regular operation of the BS. In all cases, compliance with the reference levels for general public exposure is affirmed.

Abstract
BACKGROUND Despite previous research suggesting a potential association between cerebral small vessel disease (CSVD) and epilepsy, the precise causality and directionality between cerebral small vessel disease (CSVD) and epilepsy remain incompletely understood. We aimed to investigate the causal link between CSVD and epilepsy. METHOD A bidirectional two-sample Mendelian randomization (MR) analysis was performed to evaluate the causal relationship between CSVD and epilepsy. The analysis included five dimensions of CSVD, namely small vessel ischemic stroke (SVS), intracerebral hemorrhage (ICH), white matter damage (including white matter hyperintensity [WMH], fractional anisotropy, and mean diffusivity), lacunar stroke, and cerebral microbleeds. We also incorporated epilepsy encompassing both focal epilepsy and generalized epilepsy. Inverse variance weighted (IVW) was used as the primary estimate while other four MR techniques were used to validate the results. Pleiotropic effects were controlled by adjusting vascular risk factors through multivariable MR. RESULT The study found a significant association between SVS (odds ratio [OR] 1.117, PFDR = 0.022), fractional anisotropy (OR 0.961, PFDR = 0.005), mean diffusivity (OR 1.036, PFDR = 0.004), and lacunar stroke (OR 1.127, PFDR = 0.007) with an increased risk of epilepsy. The aforementioned correlations primarily occurred in focal epilepsy rather than generalized epilepsy on subgroup analysis and retained their significance in the multivariable MR analysis. CONCLUSION Our study demonstrated that genetic susceptibility to CSVD independently elevates the risk of epilepsy, especially focal epilepsy. Diffusion tensor imaging may help screen patients at high risk for epilepsy in CSVD. Improved management of CSVD may be a significant approach in reducing the overall prevalence of epilepsy.

Abstract
OBJECTIVE To propose a new classification system (Urman-Vitale Classification System) for intrauterine adhesions (IUAs) and to evaluate anatomical and fertility outcomes after hysteroscopic adhesiolysis accordingly. METHODS A retrospective analysis of consecutive patients treated over 11 years by a single operator in a tertiary care hospital. Women with sonographic suspicion of IUAs were scheduled for hysterosalpingography (HSG) and hysteroscopy for confirmation and treatment. IUAs were divided into five classes according to symptoms, ultrasound, HSG findings, and postsurgical hysteroscopic appearance. Hysteroscopic adhesiolysis was performed using a bipolar cutting electrode in an office setting. Evaluated outcomes were restoration of the uterine cavity, clinical pregnancy, pregnancy loss, and live birth rates. RESULTS A total of 227 patients (479 procedures) were included. Mean number of hysteroscopies increased in frequency with class of adhesions from Class 1 to Class 5 (1.0 ± 0.2 vs 2.3 ± 0.5; P = 0.001). Full restoration of the cavity was achieved in 100% of patients with Class 1 compared with 18.5% for Class 5 (43/43 vs 5/27; P = 0.001). Clinical pregnancy (Class 1 vs Class 4: P = 0.034; 1 vs 5: P = 0.006; 2 vs 5: P = 0.024) and live birth (Class 1 vs Class 4: P = 0.001; 1 vs 5: P = 0.006; 2 vs 4: P = 0.007; 2 vs 5: P = 0.0208) rates decreased with increasing severity of IUAs. Pregnancy loss rate was related to IUA severity (Class 1 vs Class 4: P = 0.012; 1 vs 5: P = 0.003: 2 vs 4: P = 0.014; 2 vs 5: P = 0.021). CONCLUSION A classification based on symptoms, imaging findings, and postsurgical macroscopic appearance of the uterine cavity could be useful in predicting prognosis and fertility in women with IUAs.

Abstract
Previous studies have reported sex differences in altered brain function in patients with chronic insomnia (CI). However, sex-related alterations in brain morphology have rarely been investigated. This study aimed to investigate sex-specific grey matter (GM) alterations in patients with CI and to examine the relationship between GM alterations and neuropsychological assessments. Ninety-three (65 females and 28 males) patients and 78 healthy (50 females and 28 males) controls were recruited. Structural magnetic resonance imaging data were analysed using voxel-based morphometry to test for interactions between sex and diagnosis. Spearman's correlation was used to assess the associations among structure, disease duration, and sleep-, mood-, and cognition-related assessments. Males with CI showed reduced GM volume in the left inferior parietal lobe, left middle cingulate cortex, and right supramarginal gyrus. Females with CI showed increased GM volume in the right Rolandic operculum. Moreover, mood-related assessments were negatively correlated with GM volumes in the right supramarginal gyrus and left inferior parietal lobe in the male patients, and cognitive-related assessments were positively correlated with GM volumes in the Rolandic operculum in the female patients. Our findings indicate sex-specific alterations in brain morphology in CI, thereby broadening our understanding of sex differences in CI and potentially providing complementary evidence for the development of more effective therapies and individual treatments.

Abstract
Association between anti-GABAAR encephalitis and myasthenia gravis is extremely rare with few reported cases. Herein, we report a case of a female patient diagnosed with anti-GABAAR encephalitis and thymoma at the first admission. She was administered glucocorticoids for long-term immunotherapy, and thymectomy with biopsy demonstrated a type A thymoma. After 4 months, the symptoms of encephalitis were relieved, but she then developed post-thymectomy myasthenia gravis with anti-AChR and anti-titin dual positivity. Antibodies to connective tissue (anti-ANA, anti-PCNA) and those characteristics of paraneoplastic syndrome (anti-Ma2/Ta) were also positive. She received oral glucocorticoids and tacrolimus as immunosuppressive therapy, and myasthenic symptoms were stable during a 2-year follow-up. Our case revealed that anti-GABAAR encephalitis and myasthenia gravis can appear in patient with type A thymoma at different periods, which alerts physicians to take long-term follow-up for anti-GABAAR encephalitis with thymoma, even after thymectomy. Concurrent positivity for more than one antibody after thymectomy is rarely observed, and their contribution to the clinical course and treatment decision remains to be further investigated.

Abstract
PURPOSE Hip and knee arthroplasty aims to reduce joint pain and increase functional mobility in patients with osteoarthritis; however, the degree to which arthroplasty is associated with higher physical activity is unclear. The current study sought to assess the association of hip and knee arthroplasty with objectively measured physical activity. METHODS This cross-sectional study analyzed wrist-worn accelerometer data collected in 2013-2016 from UK Biobank participants (aged 43-78 yr). Multivariable linear regression was performed to assess step count, cadence, overall acceleration, and activity behaviors between nonarthritic controls, end-stage arthritic, and postoperative cohorts, controlling for demographic and behavioral confounders. From a cohort of 94,707 participants with valid accelerometer wear time and complete self-reported data, electronic health records were used to identify 3506 participants having undergone primary or revision hip or knee arthroplasty and 68,389 nonarthritic controls. RESULTS End-stage hip or knee arthritis was associated with taking 1129 fewer steps per day (95% confidence interval (CI), 811-1447; P < 0.001) and having 5.8 fewer minutes per day (95% CI, 3.0-8.7; P < 0.001) of moderate-to-vigorous activity compared with nonarthritic controls. Unilateral primary hip and knee arthroplasties were associated with 877 (95% CI, 284-1471; P = 0.004) and 893 (95% CI, 232-1554; P = 0.008) more steps than end-stage osteoarthritic participants, respectively. Postoperative unilateral hip arthroplasty participants demonstrated levels of moderate-to-vigorous physical activity and daily step count equivalent to nonarthritic controls. No difference in physical activity was observed between any cohorts in terms of overall acceleration, or time spent in daily light activity, sedentary behavior, or sleep. CONCLUSIONS Hip and knee arthroplasties are associated with higher levels of physical activity compared with participants with end-stage arthritis. Unilateral hip arthroplasty patients, in particular, demonstrate equivalence to nonarthritic peers at more than 1 yr after surgery.

Abstract
OBJECTIVE This study examined the quality of life and burden of disease of vulvar lichen sclerosus (VLS) patients in three states of menstruation to better understand VLS. METHODS A total of 607 VLS patients were enrolled into this retrospective study. According to the ages of onset, menarche and menopause, the patients were divided into three groups: prepubertal group (n = 96), reproductive group (n = 400) and postmenopausal group (n = 111). Data were collected by direct interview and clinical examination. RESULTS A total of 93% of patients had itching, with a median numerical rating scale score of five. In the prepubertal group, the median score was three. Nocturnal itching occurred in 49.6% patients. Nearly half of the patients (45.9%) thought the itching affected their sleep. However, this ratio was very different in the prepubertal group (20.7%). Some patients (12.8%) cleaned their vulva more than seven times per week. Only 17.2% of patients experienced no effect on their sex life. The median dermatology life quality index score in all patients was six, but it was only three in the prepubertal group. The median number of hospital visits was two times, and the number of clinic visits was three times. Previous expenses, in median, were 2000 RMB. For 84.3% patients, the gynecologic clinic was their first choice. CONCLUSION VLS places great physical, mental and economic burdens on patients. Patients in the prepubertal group had milder symptoms and dermatology life quality index score. VLS should arouse the attention of patients and specialists.

Abstract
OBJECTIVE The probability of embryo implantation in an abnormal location is significantly higher in assisted reproductive technology (ART) than in natural pregnancies. Angular pregnancy is an eccentric intrauterine pregnancy with embryo implantation in the lateral superior angle of the uterine cavity. Cycle-level factors associated with angular pregnancy in patients conceived with ART needed to be explored. METHODS A total of 11 336 clinical pregnancies cycles were included. Angular pregnancy rate was compared among groups according to the type of embryos transferred. Among them, 53 cases of angular pregnancy and 159 cases of normal intrauterine pregnancy were screened out using propensity score matching. Risk factors of angular pregnancy were explored. RESULTS The angular pregnancy rate was 0.31% (14/4572) in the day 5 blastocyst transfer group, 0.58% (39/6764) in non-day 5 embryo transfer group, with 0.55% (29/5280) in day 3 embryo transfer and 0.67% (10/1484) in the day 6 blastocyst group, respectively. A multifactor regression analysis was performed and indicated that the number of embryos transferred was significantly associated with angular pregnancy (P = 0.031, OR, 2.23, 95% CI: 1.09-4.68). CONCLUSION Multiple embryo transfer could possibly be associated with an increased incidence of angular pregnancy in patients conceived with ART.

Abstract
Delirium is a common complication in acute stroke patients. A 2011 meta-analysis showed an increased risk of in-hospital mortality and mortality within 12 months post-stroke, longer hospitalization durations, and increased likelihood of being discharged to a nursing home for patients experiencing post-stroke delirium. There is a need for an updated meta-analysis with several new studies having been since published. The PubMed and Scopus databases were screened for relevant studies. Inclusion criteria were as follows: retrospective or prospective studies reporting on the effects of delirium accompanying acute stroke on mortality, functional outcomes, length of hospital stay and need for re-admission. Strength of association was presented as pooled adjusted relative risk (RR) for categorical outcomes and weighted mean difference (WMD) for continuous outcomes. Statistical analysis was done using STATA version 16.0. The meta-analysis included 22 eligible articles. Eighteen of the 22 studies were prospective follow ups. Included studies were of good quality. Post-stroke delirium was associated with increased risk of in-hospital mortality, as well as mortality within 12 months post-stroke. Patients with delirium experienced increased hospital stay durations, were at greater risk for hospital readmission, and showed elevated risk for poor functional outcome. Compared to those who did not have delirium, stroke patients with delirium were 42% less likely to be discharged to home. Acute stroke patients with delirium are at an increased risk for poor short- and long-term outcomes. More research is needed to identify the best set of interventions to manage such patients and improve outcomes.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a widespread inflammatory disease with a high mortality rate. Long noncoding RNAs play important roles in pulmonary diseases and are potential targets for inflammation intervention. METHODS The expression of small nucleolar RNA host gene 6 (SNHG6) in mouse lung epithelial cell line MLE12 with or without cigarette smoke extract (CSE) treatment was first detected using quantitative reverse-transcription PCR. ELISA was used to evaluate the release of inflammatory cytokines (TNF-α, IL-1β, and IL-6). The binding site of miR-182-5p with SNHG6 was predicted by using miRanda, which was verified by double luciferase reporter assay. RESULTS Here, we revealed that SNHG6 was upregulated in CS-exposed MLE12 alveolar epithelial cells and lungs from COPD-model mice. SNHG6 silencing weakened CS-induced inflammation in MLE12 cells and mouse lungs. Mechanistic investigations revealed that SNHG6 could upregulate IκBα kinase through sponging the microRNA miR-182-5p, followed by activated NF-κB signaling. The suppressive effects of SNHG6 silencing on CS-induced inflammation were blocked by an miR-182-5p inhibitor. CONCLUSION Overall, our findings suggested that SNHG6 regulates CS-induced inflammation in COPD by activating NF-κB signaling, thereby offering a novel potential target for COPD treatment.

Abstract
Axenfeld-Rieger Syndrome (ARS) type 1 is a rare autosomal dominant condition characterized by anterior chamber anomalies, umbilical defects, dental hypoplasia, and craniofacial anomalies, with Meckel's diverticulum in some individuals. Here, we describe a clinically ascertained female of childbearing age with ARS for whom clinical targeted sequencing and deletion/duplication analysis followed by clinical exome and genome sequencing resulted in no pathogenic variants or variants of unknown significance in PITX2 or FOXC1. Advanced bioinformatic analysis of the genome data identified a complex, balanced rearrangement disrupting PITX2. This case is the first reported intrachromosomal rearrangement leading to ARS, illustrating that for patients with compelling clinical phenotypes but negative genomic testing, additional bioinformatic analysis are essential to identify subtle genomic abnormalities in target genes.

Abstract
BACKGROUND Globally, eclampsia is the leading cause of maternal and neonatal morbidity and mortality. OBJECTIVE The present community-based study was conducted among rural tribal women of reproductive age in remote villages of central India to determine their awareness of eclampsia and its likely impact. METHODS This cross-sectional analytic study included randomly selected 4500 tribal women, between 15 and 45 years of age, residing in 140 villages in the proximity of one village with a health facility (study center), and who were willing to undergo a personal interview. In-depth face-to-face interviews (each lasting 15-30 min) of study subjects regarding awareness, knowledge, practices, and perceptions about eclampsia were conducted using a predesigned tool completed by research assistants (not the subjects). RESULTS Of the 4500 women interviewed, the majority (62.4%) were 20-29 years old, minimally educated (40.6%), laborers (41.3%), and of a low socioeconomic class (40.8%). Of all the participants, only 35.9% were aware of eclampsia, associated events during pregnancy, labor, and the immediate post-delivery period; 81.7% of those who were aware understood about symptoms and signs like headache, blurring of vision, dizziness, swelling over the body, ad high blood pressure. Of all the women who knew about eclampsia, 73.9% were aware that the occurrence of convulsions during antenatal and postnatal periods was an emergency and required urgent management, whereas 88.4% were not aware that severe convulsions affected maternal and neonatal health seriously, only 38.2% knew that eclampsia was a preventable condition. CONCLUSION There was lack of awareness about eclampsia in many women and, of those who knew, some were not aware that it was dangerous. There is a need for awareness among women and their families of the disorder, its impact, and what action is needed in case it occurs.

Abstract
Licochalcone A (LicA), a natural compound extracted from licorice root, has been shown to exert a variety of anticancer activities. Whether LicA has such effects on endometrial cancer (EMC) is unclear. This study aims to investigate the antitumor effects of LicA on EMC. Our results show that LicA significantly reduced the viability and induced apoptosis of EMC cells and EMC-7 cells from EMC patients. LicA was also found to induce endoplasmic reticulum (ER) stress, leading to increased expression of ER-related proteins (GRP78/PERK/IRE1α/CHOP) in EMC cell lines. Suppression of GRP78 expression in human EMC cells treated with LicA significantly attenuated the effects of LicA, resulting in reduced ER-stress mediated cell apoptosis and decreased expression of ER- and apoptosis-related proteins. Our findings demonstrate that LicA induces apoptosis in EMC cells through the GRP78-mediated ER-stress pathway, emphasizing the potential of LicA as an anticancer therapy for EMC.

Abstract
OBJECTIVE To report outcomes of a large cohort of patients who underwent endoscopic endonasal transsphenoidal surgery (EETS) for resection of a pituitary adenoma with subsequent Resorb-X plate (RXP) sellar reconstruction. METHODS A retrospective review of 620 EETS operations performed at a single academic center between 2005 and 2020 was conducted. RESULTS A total of 215 EETS operations of 208 patients were identified between 2012 and 2020 who underwent reconstruction with the RXP after EETS for pituitary tumor resection with a final pathologic diagnosis of pituitary adenoma. Analysis of pooled data revealed a mean preoperative tumor volume of 6.8 cm3 (range: 0.038-51.03 cm3). Postoperative cerebrospinal fluid leak occurred in 2 patients (0.93%). Postoperative meningitis occurred in 1 patient (0.47%). There were no cases of RXP extrusion. CONCLUSIONS The rate of postoperative CSF leak and meningitis after use of the RXP for sellar reconstruction compares favorably to other methods, including use of autologous grafts and flaps. Use of RXP during EETS is a safe and efficacious method of sellar reconstruction and may obviate the need for autologous tissue reconstruction after pituitary adenoma resection.

Abstract
The population dynamics of the human microbiome have been associated with inflammatory bowel disease, cancer, obesity, autoimmune diseases, and many other human disease states. An emerging paradigm in treatment is the administration of live engineered organisms, also called next-generation probiotics. However, the efficacy of these microbial therapies can be limited by the organism's overall performance in the harsh and nutrient-limited environment of the gut. In this review, we summarize the current state of the art use of bacterial and yeast strains as probiotics, highlight the recent development of genetic tools for engineering new therapeutic functions in these organisms, and report on the latest therapeutic applications of engineered probiotics, including recent clinical trials. We also discuss the supplementation of prebiotics as a method of manipulating the microbiome and improving the overall performance of engineered live biotherapeutics.

Abstract
AIMS Disordered eating behaviour (DEB) in people with type 1 diabetes (T1D) can be screened with the Diabetes Eating Problem Survey-Revised (DEPS-R). This study aimed to investigate the psychometric properties of the DEPS-R among Dutch adults with T1D and to explore the individual items alongside the standard cut-off score of ≥20 for clinical use. METHODS The construct validity of the DEPS-R was assessed with an exploratory factor analysis, through principal axis factoring and with Spearman correlations between clinical variables and the DEPS-R. Backward logistic regression identified clinical predictors for DEPS-R scores above the cut-off. DEPS-R item responses were summarized with frequencies, means and standard deviations. RESULTS Participants were 145 adults with T1D, of whom 79.3% were women and 35.9% presented with DEB based on the cut-off. A single-factor solution of the DEPS-R showed good internal consistency, while a three-factor solution showed acceptable to good internal consistency within the factors. A younger age, a higher BMI and more diabetes distress were predictors for a DEPS-R cut-off score of ≥20. Clinically relevant items were identified that contributed minimally to the DEPS-R score. CONCLUSIONS This study supports a single-factor and a three-factor structure of the DEPS-R while also suggesting an item-specific or factor-specific approach in clinical practice.

Abstract
Diseases of the aorta, such as aortic aneurysm, dissection, and rupture, account for a large proportion of acute clinical emergencies. The red blood cell distribution width (RDW), which directly reflects anisocytosis (i.e., the heterogeneity of erythrocyte volumes), has emerged as a promising biomarker for many cardiovascular pathologies. Thus, we aimed to explore the implication of RDW in aortic pathologies. We searched Scopus and PubMed using the keywords "RDW" OR "red blood cell distribution width" AND "aortic aneurysm" OR "aortic dilatation" OR "aortic dissection" for identifying studies in which RDW values were measured in patients with these aortic diseases. Ten observational studies were finally included. In all studies, RDW value was increased in patients with aortic diseases. In the four studies in which sufficient RDW data were available for pooling, the weighted mean difference (WMD) of RDW in patients with or without complicated aortic pathologies was 0.575 (95 %CI, 0.254-0.896). RDW may be a valuable diagnostic and prognostic biomarker in patients with aortic pathologies.

Abstract
This project addresses the global challenge of breast cancer, particularly in low-resource settings, by creating a pioneering mammography database. Breast cancer, identified by the World Health Organization as a leading cause of cancer death among women, often faces diagnostic and treatment resource constraints in low- and middle-income countries. To enhance early diagnosis and address educational setbacks, the project focuses on leveraging artificial intelligence (AI) technologies through a comprehensive database. Developed in collaboration with Ambra Health, a cloud-based medical image management software, the database comprises 941 mammography images from 100 anonymized cases, with 62 % including 3D images. Accessible through http://mamografia.unifesp.br, the platform facilitates a simple registration process and an advanced search system based on 169 clinical and imaging variables. The website, customizable to the user's native language, ensures data security through an automatic anonymization system. By providing high-resolution, 3D digital images and supplementary clinical information, the platform aims to promote education and research in breast cancer diagnosis, representing a significant advancement in resource-constrained healthcare environments.

Abstract
OBJECTIVE The Adherence with Continuous Dose Oral Contraceptive: Evaluation of Self-Selection and Use (ACCESS) study assessed whether consumers can adhere to the regimen for a progestin-only pill (norgestrel 0.075 mg) in an over-the-counter (OTC) setting. STUDY DESIGN An actual use study in a simulated OTC environment assessed adherence to directions to take norgestrel 0.075 mg every day at the same time in 883 participants for up to 24 weeks. RESULTS Eighty-five percent (747/883) of participants reported ≥85% adherence to taking norgestrel 0.075 mg every day and reported taking their dose within three hours of their scheduled dosing time on 96% of days. When accounting for use of a condom for 48 hours if a pill was missed, participants reported correctly following the label's directed use for 97% of doses overall, with 95% of participants following label directions for ≥85% of doses. The main limitations were related to finding a balance between intensely collecting data to ensure accurate assessment of adherence and leaving users to behave as they would in a real OTC situation without healthcare practitioner intervention. We observed that some participants reported taking more doses than they could have based on the supply of medication given to them. To fully examine the situation, and the impact on the conclusions, additional post hoc sensitivity analyses were performed, and showed remarkably consistent results. CONCLUSIONS Consumers were highly adherent to taking norgestrel 0.075 mg when using only the information provided by the proposed OTC label. IMPLICATIONS Adherence to a daily oral contraceptive pill was high when obtained OTC. This suggests that effectiveness of an OTC pill is likely to be like that of a prescribed pill and easier access to this effective contraceptive should allow more opportunity to prevent pregnancy.

Abstract
Breast cancer is one of the most common types of cancer, representing 15 % of all new cancer cases in the United States. Approximately 12.4 % of all women will be diagnosed with breast cancer during their lifetime. In the past decades, a decrease in cancer-related mortality is evident as a result of early screening and improved therapeutic options. Nonetheless, breast cancer survivors face long-term treatment side effects, with cardiotoxicity being the most significant one, which lead to increased morbidity and mortality. Breast cancer patients are particularly susceptible to cancer therapeutics-related cardiac dysfunction (CTRCD) as treatment regimens include cardiotoxic drugs, primarily anthracyclines and anti-human epidermal growth factor receptor 2 (anti-HER2) agents (recombinant humanized monoclonal antibodies directed against HER2 such as trastuzumab and pertuzumab). Cardiotoxicity is the most common dose-limiting toxicity associated with trastuzumab. Discontinuation of trastuzumab however, can lead to worse cancer outcomes. There have been case reports, registry-based, retrospective cohort-based and mechanistic studies suggesting the cardioprotective potential of SGLT2i in CTRCD. It is not known whether SGLT2i can prevent the development of incident HF or reduce the risk of HF in patients receiving trastuzumab with or without other concurrent anti-HER2 agent or sequential anthracycline for treatment of HER2 positive breast cancer. Based on these, there is now a call for randomized controlled trials to be performed in this patient cohort to advise guideline-directed therapy for CTRCD, which will in turn also provide detailed safety information and improve cancer and cardiovascular outcomes.

Abstract
BACKGROUND AND OBJECTIVE Survival analysis plays an essential role in the medical field for optimal treatment decision-making. Recently, survival analysis based on the deep learning (DL) approach has been proposed and is demonstrating promising results. However, developing an ideal prediction model requires integrating large datasets across multiple institutions, which poses challenges concerning medical data privacy. METHODS In this paper, we propose FedSurv, an asynchronous federated learning (FL) framework designed to predict survival time using clinical information and positron emission tomography (PET)-based features. This study used two datasets: a public radiogenic dataset of non-small cell lung cancer (NSCLC) from the Cancer Imaging Archive (RNSCLC), and an in-house dataset from the Chonnam National University Hwasun Hospital (CNUHH) in South Korea, consisting of clinical risk factors and F-18 fluorodeoxyglucose (FDG) PET images in NSCLC patients. Initially, each dataset was divided into multiple clients according to histological attributes, and each client was trained using the proposed DL model to predict individual survival time. The FL framework collected weights and parameters from the clients, which were then incorporated into the global model. Finally, the global model aggregated all weights and parameters and redistributed the updated model weights to each client. We evaluated different frameworks including single-client-based approach, centralized learning and FL. RESULTS We evaluated our method on two independent datasets. First, on the RNSCLC dataset, the mean absolute error (MAE) was 490.80±22.95 d and the C-Index was 0.69±0.01. Second, on the CNUHH dataset, the MAE was 494.25±40.16 d and the C-Index was 0.71±0.01. The FL approach achieved centralized method performance in PET-based survival time prediction and outperformed single-client-based approaches. CONCLUSIONS Our results demonstrated the feasibility and effectiveness of employing FL for individual survival prediction in NSCLC patients, using clinical information and PET-based features.

Abstract
INTRODUCTION Lumpy skin disease, an economically significant bovine illness, is now found in previously unheard-of geographic regions. Vaccination is one of the most important ways to stop its further spread. AIM Therefore, in this study, we applied advanced immunoinformatics approaches to design and develop an effective lumpy skin disease virus (LSDV) vaccine. METHODS The membrane glycoprotein was selected for prediction of the different B- and T-cell epitopes by using the immune epitope database. The selected B- and T-cell epitopes were combined with the appropriate linkers and adjuvant resulted in a vaccine chimera construct. Bioinformatics tools were used to predict, refine and validate the 2D, 3D structures and for molecular docking with toll-like receptor 4 using different servers. The constructed vaccine candidate was further processed on the basis of antigenicity, allergenicity, solubility, different physiochemical properties and molecular docking scores. RESULTS The in silico immune simulation induced significant response for immune cells. In silico cloning and codon optimization were performed to express the vaccine candidate in Escherichia coli. This study highlights a good signal for the design of a peptide-based LSDV vaccine. CONCLUSION Thus, the present findings may indicate that the engineered multi-epitope vaccine is structurally stable and can induce a strong immune response, which should help in developing an effective vaccine towards controlling LSDV infection.

Abstract
INTRODUCTION Patients with a history of Opioid Use Disorder (OUD) have higher postoperative complication rates and mortality in many settings. Yet, it remains poorly understood how the opioid epidemic has affected patients undergoing major lower extremity amputation (LEA) and whether outcomes differ by OUD status. METHODS We conducted a retrospective chart review of all 689 patients who underwent major LEA at a large tertiary referral center from 2015 to 2021. This study assessed patient characteristics and long-term postoperative outcomes for patients with preoperative OUD. RESULTS 133 (19.3%) patients had a lifetime history of preoperative OUD. Preoperative OUD was associated with key characteristics, comorbidities, and outcome measures. OUD was significantly associated with younger age (P < .001), black race (P = .026), single relationship status (P < .001), BMI <30 (P = .024), no primary care provider (P = .004), and Medicaid insurance (P < .001). Comorbidities significantly associated with OUD include current smoking (P < .001), Human Immunodeficiency Virus (HIV; P = .003), and history of osteomyelitis (P < .001). Preoperative OUD independently predicted lower rates of 30-60-day readmission (odds ratio [OR] .54, P = .018) and 1-12-month reamputation (OR .41, P = .006). There was no significant difference in long-term mortality and follow-up. CONCLUSION This study demonstrates the prevalence of OUD in patients undergoing major LEA and reports associations and long-term outcomes. Our findings highlight the importance of recognizing OUD and raise questions about the mechanisms underlying its relation to rates of postoperative readmission and reamputation.

Abstract
A unique feature of the tumor microenvironment is extracellular acidosis in relation to intracellular milieu. Metabolic reprogramming in tumors results in overproduction of H+ ions (and lactate), which are extruded from the cells to support tumor survival and progression. As a result, the transmembrane pH gradient (ΔpH), representing the difference between intracellular pH (pHi) and extracellular pH (pHe), is posited to be larger in tumors compared with normal tissue. Controlling the transmembrane pH difference has promise as a potential therapeutic target in cancer as it plays an important role in regulating drug delivery into cells. The current study shows successful development of an MRI/MRSI-based technique that provides ΔpH imaging at submillimeter resolution. We applied this technique to image ΔpH in rat brains with RG2 and U87 gliomas, as well as in mouse brains with GL261 gliomas. pHi was measured with Amine and Amide Concentration-Independent Detection (AACID), while pHe was measured with Biosensor Imaging of Redundant Deviation in Shifts (BIRDS). The results indicate that pHi was slightly higher in tumors (7.40-7.43 in rats, 7.39-7.47 in mice) compared with normal brain (7.30-7.38 in rats, 7.32-7.36 in mice), while pHe was significantly lower in tumors (6.62-6.76 in rats, 6.74-6.84 in mice) compared with normal tissue (7.17-7.22 in rats, 7.20-7.21 in mice). As a result, ΔpH was higher in tumors (0.64-0.81 in rats, 0.62-0.65 in mice) compared with normal brain (0.13-0.16 in rats, 0.13-0.16 in mice). This work establishes an MRI/MRSI-based platform for ΔpH imaging at submillimeter resolution in gliomas.

Abstract
BACKGROUND Myxoid neurofibromas (NF) are uncommon, benign spindle cell tumors that originate from peripheral nerve sheaths, often posing a diagnostic challenge due to their hypocellularity on cytology specimens. Distinguishing myxoid spindle cell lesions can be challenging, given the broad range of potential differential diagnoses. CASE PRESENTATION A 26-year-old female with a past medical history of embolized inguinal, flank, and retroperitoneal venolymphatic malformation presented with a left pelvic pain causing significant disability. CT scan showed an extensive 8.7 cm × 6.6 cm retroperitoneal mass. FNA was performed and alcohol-fixed papanicolaou-stained smears showed a hypocellular specimen with loosely arranged clusters of bland spindle cell proliferation in the background of a mucoid matrix. Spindle cells showed scant cytoplasm and elongated oval-shaped regular nuclei. Prominent nucleoli were not seen. An excisional biopsy revealed a bland spindle cell proliferation in a myxoid background associated with shredded collagen bundles. Immunohistochemical staining showed diffuse positivity for S100 and CD34. Based on the overall findings, a definitive diagnosis of myxoid neurofibroma was rendered. DISCUSSION Cytological features of myxoid neurofibroma include the presence of hypocellular spindle-shaped cells arranged in small, loosely organized groups within a myxoid matrix background. Cells exhibit scant cytoplasm with regular oval and elongated nuclei. Nucleoli are typically not identified. The differential diagnosis includes myxoid neurofibroma, myxoma, myxoid liposarcoma, myxoid chondrosarcoma, myxoid dermatofibrosarcoma protuberans, low-grade fibromyxoid sarcoma, and low-grade myxo-fibrosarcoma. CONCLUSION We aim to highlight the importance of considering myxoid neurofibroma in the differential diagnosis of hypocellular myxoid spindle cell lesions encountered on fine-needle aspiration cytology.

Abstract
PURPOSE OF REVIEW Elite controllers (ECs) and Posttreatment controllers (PTCs) represent a small subset of individuals who are capable of maintaining drug-free control of HIV plasma viral loads despite the persistence of a replication-competent viral reservoir. This review aims to curate recent experimental studies evaluating viral reservoirs that distinguish EC/PTC and may contribute to their ability to maintain undetectable viral loads in the absence of antiretroviral therapy. RECENT FINDINGS Recent studies on ECs have demonstrated that integration sites of intact proviruses in EC/PTC are markedly biased towards heterochromatin regions; in contrast, intact proviruses in accessible and permissive chromatin were profoundly underrepresented. Of note, no such biases were noted when CD4 + T cells from EC were infected directly ex vivo, suggesting that the viral reservoir profile in EC is not related to altered integration site preferences during acute infection, but instead represents the result of immune-mediated selection mechanisms that can eliminate proviruses in transcriptionally-active euchromatin regions while promoting preferential persistence of intact proviruses in nonpermissive genome regions. Proviral transcription in such "blocked and locked" regions may be restricted through epigenetic mechanisms, protecting them from immune-recognition but presumably limiting their ability to drive viral rebound. While the exact immune mechanisms driving this selection process remain undefined, recent single-cell analytic approaches support the hypothesis that HIV reservoir cells are subject to immune selection pressure by host factors. SUMMARY A "blocked and locked" viral reservoir profile may constitute a structural virological correlate of a functional cure of HIV-1 infection. Further research into the immunological mechanism promoting HIV-1 reservoir selection and evolution in EC/PTC is warranted and could inform foreseeable cure strategies.

Abstract
Chimeric antigen receptor (CAR) T-cell therapy has become a commercially available treatment option for relapsed or refractory (r/r) diffuse large B-cell lymphoma (DLBCL) with two or more lines of prior therapies, and recently for high-risk r/r DLBCL with one prior line of therapy. The successful development of CAR T-cell therapy for multiple relapsed DLBCL has led to a boom in subsequent trials that investigated its utility in patients with other r/r B-cell lymphoma subtypes. However, CAR T-cell therapy is a multistep process that includes leukapheresis and manipulation which take several weeks. Therefore, patients with rapidly progressing or bulky disease may not be able to complete the therapeutic regimen involving CAR T-cell products. This raises the question of the generalizability of the results of pivotal studies to the entire population. In this review, we summarize the development of CAR-T cell therapy for B-cell lymphoma and discuss strategies to further improve the clinical outcomes of this treatment.

Abstract
AIM Currently, screening of colorectal cancers (CRC) by assessing mismatch repair deficiency (dMMR) or microsatellite instability (MSI) is used to identify Lynch syndrome (LS) patients. Advanced adenomas are considered immediate precursor lesions of CRC. In this study we investigate the relevance of screening of advanced adenomas for LS in population screening. METHODS AND RESULTS Advanced adenomas (n = 1572) were selected from the Dutch colorectal cancer population screening programme, based on one or more of the criteria: tubulovillous (n = 848, 54%) or villous adenoma (n = 118, 7.5%), diameter ≥ 1 cm (n = 1286, 82%) and/or high-grade dysplasia (n = 176, 11%). In 86 cases (5%), all three criteria were fulfilled at the same time. MMR-IHC and/or MSI analyses were performed on all cases. Only five advanced adenomas (0.3%) showed dMMR and MSI, including two cases with hypermethylation. In at least two patients a germline event was suspected based on allelic frequencies. No pathogenic explanation was found in the last case. CONCLUSION Timely testing of precursor lesions would be preferable to detect new LS patients before CRC development. However, standard assessment of dMMR of advanced adenomas from the population screening is not effective.

Abstract
PURPOSE OF REVIEW Recent advancements in the management of clinical stage II (CS II) testicular cancer have transformed it into a predominantly curable condition. This success in treatment advancements has markedly extended patient survival. However, these treatments carry risks and morbidities, which is important to consider given the disease's impact on young men and the emerging understanding of long-term treatment consequences. RECENT FINDINGS Emerging data support primary retroperitoneal lymph node dissection (RPLND) for select CS II seminoma patients, with similar short-term outcomes to chemotherapy but less treatment intensity. Recent studies have also challenged the reflexive use of adjuvant chemotherapy for pathologic node-positive disease, as growing evidence shows low relapse rates regardless of nodal stage. Furthermore, novel biomarkers like circulating serum microRNA-371a-3p levels can help predict the presence of viable germ cell tumor at time of RPLND. SUMMARY Advances in risk stratification and therapy enable personalized de-escalation approaches for oligometastatic testicular cancer, optimizing survivorship. Upfront RPLND, reassessing adjuvant systemic therapy for RPLND pN+ disease, and novel biomarkers will shape precision treatment to achieve high cure rates with excellent quality of life. Ongoing trials of reduced-intensity regimens, accurate prognostic models, improved surgical strategy, and emerging biomarkers represent the next frontier in tailored curative therapy.

Abstract
Dedifferentiated/undifferentiated melanoma (DM/UM) is a distinct subtype of malignant melanoma that tends to lose all melanocytic markers of differentiation. DM/UM pose major diagnostic challenges as they could be easily confused with UM sarcoma or carcinoma, thus necessitating the use of molecular studies such as Next Generation Sequencing (NGS) for detecting melanoma-compatible mutations to confirm such diagnosis. The capability of performing NGS molecular studies on small biopsy material with confirmation of adequacy via rapid on-site evaluation (ROSE) has tremendous value in diagnosing DM/UM. Herein, we present the first reported case of metastatic DM/UM to the gall bladder arising in a 60-year-old female with a prior history of right knee melanoma. We also shed light on the cytomorphology of DM/UM, review the literature on such a challenging entity, and emphasize the crucial role of molecular testing in their diagnosis.
