Informant characteristics influence Clinical Dementia Rating Sum of Boxes scores-based staging of Alzheimer's disease.

The Clinical Dementia Rating Sum of Boxes (CDR-SB) is a staging scale for Alzheimer's disease (AD)1 and is commonly used as an outcome in clinical trials2. It relies on information provided by the patient and an informant3. The CDR-SB should reflect only the patient's disease severity. However, we explored whether informant characteristics were associated with CDR-SB scores because that association might introduce bias in Alzheimer's disease research. We found that the CDR-SB was 0.20 higher when informants were female, 0.39 higher when the informant was a patient's child and 0.18 lower if the relationship was other than spouse or children. Regarding the frequency of contact, CDR-SB scores were 0.38 higher when contact was at least once a week, 0.65 higher when daily and 0.57 higher when living with the patient. Our analysis results suggest that informant characteristics can modify the CDR-SB scores and might introduce bias into Alzheimer's disease trials and research.

Dental implantation in patients with comorbid diseases: yes or no?

Patients with multiple pathologies are a high-risk group, which requires a personalized approach to surgical rehabilitation in dentistry. Inadequate diagnosis of clinical manifestations when a patient is in remission often leads to severe surgical complications. However, modern methods of dental implantation and rehabilitation are possible even in patients with oncology, those who underwent surgical therapy, chemo- or radiotherapy. Gilbert syndrome, one of the risk factors for post-surgery inflammatory complications, is associated with defects in bilirubin metabolism. It inhibits platelet activity. It is a genetic disease leading to a loss of liver enzyme activity and the accumulation of indirect bilirubin that can aggravate the course of other diseases in patients. In acute stages, it is characterized by jaundice of the skin, eyes, and mucosa and is followed by immunosuppression and the post-surgical complications associated with it. A patient with Gilbert syndrome was administered for surgical treatment of a chronic infection and follow-up rehabilitation via dental implantation and reconstruction of the bone. In this case, we faced Gilbert syndrome in association with polycythemia (a myeloproliferative disease in the compensation stage). In such cases, dental implantation cannot be achieved in the complex dental rehabilitation process. Such diseases require special attention from dental surgeons due to possible complications (bleeding, thrombosis, or disseminated intravascular coagulation). In this specific case, the patient belongs to the risk group, and its history, although in remission, is still a contraindication for dental surgery and dental implantation.

Immune system benefits of pulmonary rehabilitation in chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by pulmonary and systemic inflammation. Inflammatory mediators show relationships with shortness of breath, exercise intolerance and health related quality of life. Pulmonary rehabilitation (PR), a comprehensive education and exercise training programme, is the most effective therapy for COPD and is associated with reduced exacerbation and hospitalization rates and increased survival. Exercise training, the primary physiological intervention within PR, is known to exert a beneficial anti-inflammatory effect in health and chronic diseases. The question of this review article is whether exercise training can also make such a beneficial anti-inflammatory effect in COPD. Experimental studies using smoke exposure mice models suggest that the response of the immune system to exercise training is favourably anti-inflammatory. However, the evidence about the response of most known inflammatory mediators (C-reactive protein, tumour necrosis factor α, interleukin 6, interleukin 10) to exercise training in COPD patients is inconsistent, making it difficult to conclude whether regular exercise training has an anti-inflammatory effect in COPD. It is also unclear whether COPD patients with more persistent inflammation are a subgroup that would benefit more from hypothesized immunomodulatory effects of exercise training (i.e., personalized treatment). Nevertheless, it seems that PR combined with maintenance exercise training (i.e., lifestyle change) might be more beneficial in controlling inflammation and slowing disease progress in COPD patients, specifically in those with early stages of disease.

Stemness in solid malignancies: coping with immune attack.

Immunotherapy has become a key new pillar of cancer treatment, and this has sparked interest in understanding mechanisms of cancer immune evasion. It has long been appreciated that cancers are constituted by heterogeneous populations of tumour cells. This feature is often fuelled by specialized cells that have molecular programs resembling tissue stem cells. Although these cancer stem cells (CSCs) have capacity for unlimited self-renewal and differentiation, it is increasingly evident that some CSCs are capable of achieving remarkable immune resistance. Given that most immunotherapy regiments have overlooked CSC-specific immune-evasive mechanisms, many current treatment strategies often lead to cancer relapse. This Review focuses on advancements in understanding how CSCs in solid tumours achieve their unique immune-evasive properties, enabling them to drive tumour regrowth. Moreover, as cancers often arise from tissue stem cells that acquired oncogenic mutations, we discuss how tissue stem cells undergoing malignant transformation activate intrinsic immune-evasive mechanisms and establish close interactions with suppressive immune cells to escape immune surveillance. In addition, we summarize how in advanced disease stages, CSCs often hijack features of normal stem cells to resist antitumour immunity. Finally, we provide insights in how to design a new generation of cancer immunotherapies to ensure elimination of CSCs.

Cerebral hyperactivation across the Alzheimer's disease pathological cascade.

Neuronal dysfunction in specific brain regions or across distributed brain networks is a known feature of Alzheimer's disease. An often reported finding in the early stage of the disease is the presence of increased functional MRI (fMRI) blood oxygenation level-dependent signal under task conditions relative to cognitively normal controls, a phenomenon known as 'hyperactivation'. However, research in the past decades yielded complex, sometimes conflicting results. The magnitude and topology of fMRI hyperactivation patterns have been found to vary across the preclinical and clinical spectrum of Alzheimer's disease, including concomitant 'hypoactivation' in some cases. These incongruences are likely due to a range of factors, including the disease stage at which the cohort is examined, the brain areas or networks studied and the fMRI paradigm utilized to evoke these functional abnormalities. Additionally, a perennial question pertains to the nature of hyperactivation in the context of Alzheimer's disease. Some propose it reflects compensatory mechanisms to sustain cognitive performance, while others suggest it is linked to the pathological disruption of a highly regulated homeostatic cycle that contributes to, or even drives, disease progression. Providing a coherent narrative for these empirical and conceptual discrepancies is paramount to develop disease models, understand the synergy between hyperactivation and the Alzheimer's disease pathological cascade and tailor effective interventions. We first provide a comprehensive overview of functional brain changes spanning the course from normal ageing to the clinical spectrum of Alzheimer's disease. We then highlight evidence supporting a close relationship between fMRI hyperactivation and in vivo markers of Alzheimer's pathology. We primarily focus on task-based fMRI studies in humans, but also consider studies using different functional imaging techniques and animal models. We then discuss the potential mechanisms underlying hyperactivation in the context of Alzheimer's disease and provide a testable framework bridging hyperactivation, ageing, cognition and the Alzheimer's disease pathological cascade. We conclude with a discussion of future challenges and opportunities to advance our understanding of the fundamental disease mechanisms of Alzheimer's disease, and the promising development of therapeutic interventions incorporating or aimed at hyperactivation and large-scale functional systems.

Exploring the complexity, treatment challenges, and outcomes in pediatric nodular lymphocyte predominant Hodgkin lymphoma: a perspective from a low–middle-income country

BackgroundIn children, nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is an uncommon subtype of Hodgkin lymphoma. Given the lack of data on the best chemotherapy regimen, there is a knowledge gap in best management.MethodsThis retrospective study included all pediatric patients with NLPHL diagnosed and treated at the Children’s Cancer Hospital, Egypt (2007–2018). We analyzed the clinical characteristics, and treatment outcome according to disease stage (early and advanced), treatment strategy (doxorubicin, bleomycin, vinblastine, and dacarbazine [ABVD] or rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone [R-CHOP] and explored the prognostic factors for progression-free survival.ResultsThe median age at diagnosis was 12 years; 40 (68%) patients had early-stage disease, and 19 (32%) had advanced-stage disease. The median follow-up was 70 months; the 5-year EFS and OS were 75% and 97%, respectively. The 5-year EFS was 78% for early-stage disease and 60% for advanced-stage disease; the 5-year OS was 100% for early-stage disease and 88% for advanced-stage disease. The patients who underwent R-CHOP had a better 3-year EFS (100%) compared with those who underwent ABVD (65%) regimen (P = 0.01). Seventeen (25%) patients relapsed: 9/40 (22%) had early-stage disease, and 8/19 (42%) had advanced-stage disease. Splenic involvement, mediastinal disease, extranodal disease, and slow early response were independent predictors of relapse risk.ConclusionPediatric patients with early-stage NLPHL have an excellent prognosis, with a 5-year OS of 100%. However, those with advanced stages had a high relapse rate. R-CHOP was associated with a better response and relapse-free rate than ABVD.

Relative burden of cancer and noncancer mortality among long-term survivors of differentiated thyroid cancer in the US

BackgroundLimited information is available regarding the relative risks of cancer-specific mortality and noncancer-specific mortality among long-term survivors with differentiated thyroid cancer (DTC).MethodsIn this retrospective study, nationwide data from the Surveillance, Epidemiology, and End Results database (1992-2020) were utilized. The Accelerated Failure Time Model was applied to calculate Survival Time Ratios (TR), with the primary focus on mortality resulting from DTC. The competing risks model was employed to investigate the relative risks of various outcomes in DTC patients with a survival duration of 5 years or more.ResultsIn our cohort, 279 patients succumbed to DTC, while 748 died from other diseases. Notably, in DTC cohorts, noncancer-specific mortality rates were consistently higher than DTC-specific mortality rates across different age groups and genders. The risk of DTC and noncancer-specific mortality varied based on the TNM stage. With more advanced disease stages, the risk of DTC and other cancer-specific mortality gradually increased. The cumulative mortality from other cancer-specific causes was consistently the lowest.ConclusionsIn long-term surviving DTC patients, noncancer-specific mortality outweighed DTC-specific mortality irrespective of age and gender. For stage I and II patients, increased attention should be directed toward noncancer-specific mortality in postoperative follow-ups. Conversely, for stage III and IV patients, greater consideration should be given to DTC-related causes of death. In addition, for stage III and IV DTC patients, the risk of death from other cancers was significantly higher than for stages I and II.

Delineating three distinct spatiotemporal patterns of brain atrophy in Parkinson's disease.

The clinical manifestation of Parkinson's disease exhibits significant heterogeneity in the prevalence of non-motor symptoms and the rate of progression of motor symptoms, suggesting that Parkinson's disease can be classified into distinct subtypes. In this study, we aimed to explore this heterogeneity by identifying a set of subtypes with distinct patterns of spatiotemporal trajectories of neurodegeneration. We applied Subtype and Stage Inference (SuStaIn), an unsupervised machine learning algorithm that combined disease progression modelling with clustering methods, to cortical and subcortical neurodegeneration visible on 3 T structural MRI of a large cross-sectional sample of 504 patients and 279 healthy controls. Serial longitudinal data were available for a subset of 178 patients at the 2-year follow-up and for 140 patients at the 4-year follow-up. In a subset of 210 patients, concomitant Alzheimer's disease pathology was assessed by evaluating amyloid-β concentrations in the CSF or via the amyloid-specific radiotracer 18F-flutemetamol with PET. The SuStaIn analysis revealed three distinct subtypes, each characterized by unique patterns of spatiotemporal evolution of brain atrophy: neocortical, limbic and brainstem. In the neocortical subtype, a reduction in brain volume occurred in the frontal and parietal cortices in the earliest disease stage and progressed across the entire neocortex during the early stage, although with relative sparing of the striatum, pallidum, accumbens area and brainstem. The limbic subtype represented comparative regional vulnerability, which was characterized by early volume loss in the amygdala, accumbens area, striatum and temporal cortex, subsequently spreading to the parietal and frontal cortices across disease stage. The brainstem subtype showed gradual rostral progression from the brainstem extending to the amygdala and hippocampus, followed by the temporal and other cortices. Longitudinal MRI data confirmed that 77.8% of participants at the 2-year follow-up and 84.0% at the 4-year follow-up were assigned to subtypes consistent with estimates from the cross-sectional data. This three-subtype model aligned with empirically proposed subtypes based on age at onset, because the neocortical subtype demonstrated characteristics similar to those found in the old-onset phenotype, including older onset and cognitive decline symptoms (P < 0.05). Moreover, the subtypes correspond to the three categories of the neuropathological consensus criteria for symptomatic patients with Lewy pathology, proposing neocortex-, limbic- and brainstem-predominant patterns as different subgroups of α-synuclein distributions. Among the subtypes, the prevalence of biomarker evidence of amyloid-β pathology was comparable. Upon validation, the subtype model might be applied to individual cases, potentially serving as a biomarker to track disease progression and predict temporal evolution.

Evaluation of Circulating Tumor DNA and Carcinoembryonic Antigen Levels and Relationship with Clinicopathological Risk Factors and Prognostic Indices in Colorectal Cancer Patients

Objective: Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. ctDNA has emerged as a promising biomarker for CRC management, offering real-time insights into tumor burden and genetic mutations. This study investigates the correlation between CEA levels, ctDNA, clinicopathological factors, and treatment outcomes in early and advanced CRC patients. Methods: The study retrospectively analyzed data from CRC patients, including early-stage disease and metastatic disease. ctDNA levels, demographic data, and clinical parameters such as CEA, inflammatory indexes, and tumor characteristics were evaluated to determine correlations with treatment outcomes. Results: The study included 20 patients, with 60% diagnosed at the metastatic stage. The study found no statistically significant correlation between ctDNA levels and disease stage, recurrence, or overall survival. While CEA and ctDNA levels were measured, they did not demonstrate a significant relationship with treatment outcomes. Notably, ctDNA levels were higher in metastatic patients, though this was not statistically significant. Conclusion: Despite its potential, the integration of ctDNA as a routine biomarker in CRC care faces challenges, including variability in measurement techniques and cost-effectiveness. However, ctDNA's ability to guide personalized treatment strategies and monitor disease recurrence holds promise. The study's findings align with previous research, suggesting ctDNA as a poor prognostic indicator, though further research is needed. ctDNA represents a significant advance in CRC management, offering non-invasive, real-time insights into tumor dynamics. Ongoing research is expected to solidify its role in personalized treatment planning, potentially leading to more effective and tailored therapies for CRC patients.

Efficacy of endoscopic interventions versus surgery for pain management in patients with chronic calcific pancreatitis: a systematic review and meta-analysis.

Chronic calcific pancreatitis (CCP) is a debilitating inflammatory condition characterized by the accumulation of calcific deposits in the pancreatic tissue, leading to chronic abdominal pain and functional insufficiencies. This study aims to systematically review and meta-analyse comparative studies assessing the efficacy of endotherapy versus surgery in managing CCP-related pain. MEDLINE, EMBASE, and Cochrane library (CENTRAL and CDSR), from inception to October 2023, were searched. The inclusion criteria encompassed randomized controlled trials (RCTs) and non-randomized controlled trials (NRS), and cohort studies comparing endoscopic interventions to surgery for pain management in patients with CCP. Pain relief, procedural technical success, and procedural-related complications were the outcomes of interest. Two review authors (CN, KK) independently assessed study eligibility criteria and performed data extraction. Using a random-effects model, pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated. The level of certainty of the evidence was assessed using the GRADE approach. Five studies were included. For the outcome of pain relief, a meta-analysis of five studies (3 RCTs and 2 cohort studies) demonstrated a significant therapeutic effect in favour of surgery with an OR of 2.36 (95% CI: 1.12 to 5.00, I2 = 41.70), with moderate level of certainty of evidence. In the analysis of five studies (3 RCTs, 1 NRS and 2 cohort studies), procedural technical success was comparable between the two groups (OR of 3.02, 95% CI: 0.47 to 19.59, I2 = 79.27%) as were adverse events (OR 1.31, 95% CI: 0.47 to 3.70, I2 = 50.93%). In conclusion, this systematic review and meta-analysis suggest that surgery may be more effective in relieving pain in patients with CCP compared to endoscopic interventions. Disease stage may be important to determine the appropriateness of each procedure. PROSPERO (CRD42023476153).

Hepatitis B Virus-Associated Liver Carcinoma: The Role of Iron Metabolism and Its Modulation.

Hepatitis B virus (HBV) infection is a significant contributor to the development of hepatocellular carcinoma (HCC), a leading cause of cancer-related mortality worldwide. Iron, a central co-factor in various metabolic pathways, plays an essential role in liver function, but its dysregulation can lead to severe health consequences. Accumulation of iron within hepatic cells over time is linked to increased liver injury and is strongly associated with sensitive exposure to a range of conditions, including cirrhosis, fibrosis and ultimately, HCC. This review explores the intricate interplay between iron metabolism and HCC within the context of HBV infection. Hepatic iron overload can arise from liver injury and disruptions in iron homeostasis, causing hepatic necrosis, inflammation, and fibrosis, ultimately culminating in carcinogenesis. Moreover, alterations in serum iron components in HBV-related scenarios have been observed to impact the persistence of HBV infection. Notably, the progression of HBV-associated liver damage exhibits distinct characteristics at various stages of liver disease. In addition to elucidating the complex relationship between iron metabolism and HCC in the context of HBV infection, this review also investigates the prognostic implications of systemic iron levels for HCC. Furthermore, it aims to provide a comprehensive understanding of the intricate interplay between iron metabolism and HCC, extending the discussion to the context of hepatitis C virus (HCV) infection. By shedding light on these multifaceted connections, this review aims to contribute to our understanding of the pathogenesis of HBV-associated HCC and potentially identify novel therapeutic avenues for intervention.

Clinical outcome of ultrasonographic detected undifferentiated synovitis in patients with arthralgia

BackgroundIn the early stages of rheumatic diseases, individuals may present with nonspecific musculoskeletal symptoms (such as arthralgia) in the absence of clinical synovitis. Ultrasound (US) looks potentially helpful, particularly in the absence of symptomatic arthritis. This research aims to study the clinical outcomes of undifferentiated synovitis detected by ultrasound in patients who complain of arthralgia and their predicting factors.ResultsFrom 174 patients with arthralgia, 42% of cases went into remission, and 58% remained as persistent inflammatory arthritis (PIA) (26.4% persisted as undifferentiated arthritis, 31.6% differentiated into specific rheumatic diseases of whom 9.2% became rheumatoid arthritis, 6.3% developed spondyloarthropathy, and other diseases) after 2 years of follow-up. Regression analysis showed that patients with Power Doppler (PD) grade (I or II), grayscale (GS) synovitis grade (II or III), and GS synovitis ≥ grade II in one wrist were significant predictors for PIA in undifferentiated arthralgia’s patients.ConclusionsApproximately 60% of patients with arthralgia developed inflammatory arthritis (IA) after 2 years of follow-up, with 77% of them having US synovitis at the onset of the study. A positive PD signal, grade (II or III) GS synovitis, or ≥ grade II at one wrist were all independently related to the development of PIA in arthralgia patients.

Chemogenetic neuronal silencing decouples c-Jun activation from cell death in the temporal cortex.

Initial symptoms of neurodegenerative diseases are often defined by the loss of the most vulnerable neural populations specific to each disorder. In the early stages of Alzheimer's disease, vulnerable circuits in the temporal lobe exhibit diminished activity prior to overt degeneration. It remains unclear whether these functional changes contribute to regional vulnerability or are simply a consequence of pathology. We previously found that entorhinal neurons in the temporal cortex undergo cell death following transient suppression of electrical activity, suggesting a causal role for activity disruption in neurodegeneration. Here we demonstrate that electrical arrest of this circuit stimulates the injury-response transcription factor c-Jun. Entorhinal silencing induces transcriptional changes consistent with c-Jun activation that share characteristics of gene signatures in other neuronal populations vulnerable to Alzheimer's disease. Despite its established role in the neuronal injury response, inhibiting c-Jun failed to ameliorate entorhinal degeneration following activity disruption. Finally, we present preliminary evidence of integrated stress response activity that may serve as an alternative hypothesis to what drives entorhinal degeneration after silencing. Our data demonstrate that c-Jun is activated in response to neuronal silencing in the entorhinal cortex but is decoupled from subsequent neurodegeneration.

The 2018 Classification of Periodontal Diseases: An Observational Study on Inter-examiner Agreement among Undergraduate Students.

The objective of the present observational study was to assess the inter-examiner agreement for the diagnosis of periodontitis using the 2018 CPD among fourth and fifth year undergraduate students. It is hypothesised that there is no difference in the inter-examiner relaibility between fourth- and fifth-year undergraduate students regarding staging and grading periodontal disease using the 2018 Classification of Periodontal Diseases (CPD). All participants received training on the 2018 CPD scheme through a mandatory periodontics course conducted by a periodontist. Documentation for seven deidentified periodontitis patients, comprising medical history, dental history including tooth loss, intra-oral photographs and radiographs, periodontal charts reporting probing depth, plaque and bleeding on probing scores, furcation involvement and clinical attachment loss, was sent via e-mail to undergraduate students. The cases consisted of one sextant, and the participants were instructed to assume the sextant to be a true representation of the entire dentition. Power analysis was done on pilot data, and the level of significance was set at p0.05. The percentage of undergraduate students in the fourth and fifth year that correctly identified the stage of periodontitis according to the 2018 CPD ranged between 28% and 72% and 18.5% and 77.8%, respectively. The percentage of undergraduate students in the fourth and fifth year that correctly identified the grade of periodontitis ranged between 40% and 88% and 51.8% and 92.5%, respectively. The overall staging and grading ranged between 22.8% and 74.1%, and 45.66% and 87.4%, respectively. There was no statistically significant difference between fourth- and fifth-year undergraduate students with regards to assigning the correct diagnoses to case documentation in terms of either stage or grade. Fourth- and fifth-year undergraduate students demonstrated high inter-examiner agreement using the 2018 CPD.

Treatment and survival differences between patients with invasive lobular carcinoma versus invasive ductal carcinoma of the breast.

Invasive lobular carcinoma (ILC) exhibits differences in molecular and biological characteristics compared to invasive ductal carcinoma (IDC). We aim to compare breast cancer-specific survival (BCSS) between patients with ILC and IDC. We used data from the Surveillance, Epidemiology, and End Results database (1992-2020). Logistic regression analyses were conducted to identify factors associated with treatment modalities. We examined BCSS at different time points using a cox regression model with time-dependent coefficient. 343,397 patients with IDC and 39,859 patients with ILC were included. Patients with ILC had more advanced stage disease (stage II, 35% vs. 34%; stage III, 16% vs.11%), and higher rate of hormone receptor-positive disease (97% vs. 81%). Compared to patients with IDC, patients with ILC had better BCSS in the first five years (Hazard ratio [HR]=0.71, p <0.001), but worse BCSS in later years (HR=1.30, p<0.001 in year 6-10; HR=1.75, p<0.001 in year 11-15; HR=2.17, p<0.001 in year 16-20). Patients with ILC survive better in early years but worse in later years compared to patients with IDC. Future studies are required to identify patients with ILC who are at risk of late recurrence or mortality. The results of this study add to the currently conflicting literature of survival of ILC and demonstrate the importance of evaluating novel therapeutic approaches and extended therapy for patients with ILC.

The role of ethnic enclaves and neighborhood socioeconomic status in invasive breast cancer incidence rates among Asian American, Native Hawaiian, and Pacific Islander females in California.

Few studies have examined whether the incidence rates of invasive breast cancer among Asian American, Native Hawaiian, and Pacific Islander (AANHPI) populations differ by the neighborhood social environment. Thus, we examined associations of ethnic enclave and neighborhood socioeconomic status (nSES) with breast cancer incidence rates among AANHPI females in California. A total of 14,738 AANHPI females diagnosed with invasive breast cancer in 2008-2012 were identified from the California Cancer Registry. AANHPI ethnic enclaves (culturally distinct neighborhoods) and nSES were assessed at the census tract level using 2007-2011 American Community Survey data. Breast cancer age-adjusted incidence rates and incidence rate ratios (IRRs) were estimated for AANHPI ethnic enclave, nSES, and their joint effects. Subgroup analyses were conducted by stage of disease. The incidence rate of breast cancer among AANHPI females living in lowest ethnic enclave neighborhoods (quintile (Q)1) were 1.21 times (95% Confidence Interval (CI) 1.11, 1.32) that of AANHPI females living highest ethnic enclave neighborhoods (Q5). In addition, AANHPI females living in highest vs. lowest SES neighborhoods had higher incidence rates of breast cancer (Q5 vs. Q1 IRR = 1.30, 95% CI 1.22 to 1.40). The incidence rate of breast cancer among AANHPI females living in low ethnic enclave + high SES neighborhoods was 1.32 times (95% CI 1.25, 1.39) that of AANHPI females living in high ethnic enclave + low SES neighborhoods. Similar patterns of associations were observed for localized and advanced stage disease. For AANHPI females in California, incidence rates of breast cancer differed by nSES, ethnic enclave, when considered independently and jointly. Future studies should examine whether the impact of these neighborhood-level factors on breast cancer incidence rates differ across specific AANHPI ethnic groups and investigate the pathways through which they contribute to breast cancer incidence.

Copaiba Oleoresin Improves Weight Gain and IL-10 Concentration, with No Impact on Hepatic Histology, in Liver Cirrhosis

Copaifera sp. is a native tree in the Amazon region. Copaiba oleoresin has components such as sesquiterpenes, which have anti-inflammatory and antioxidant potential. Liver cirrhosis is the end stage of liver disease with limited therapeutic options. We aimed to evaluate the effect of copaiba oleoresin supplementation on the liver of animals with thioacetamide (TAA)-induced cirrhosis. For the induction of liver cirrhosis, 100 mg/kg of TAA was administered intraperitoneally twice a week for 8 weeks. A total of 200 mg/kg/day of copaiba oleoresin was administered via gavage for the same period. Copaiba oleoresin supplementation improved cirrhosis-associated cachexia by increasing weight gain and body fat. In addition, copaiba oleoresin attenuated systemic inflammation, as shown by the decrease in the circulating C-reactive protein. In the liver, the copaiba oleoresin decreased carbonyl proteins and increased IL-10 compared with TAA-treated rats. TAA groups demonstrated increased SOD, catalase, GST, and GSH activity in the liver. In conclusion, the supplementation of copaiba oleoresin demonstrated a beneficial systemic effect in alleviating cirrhotic cachexia and antioxidant and anti-inflammatory action in the liver. However, it failed to improve the serological and histological markers of liver damage, which could be associated with the advanced stage of the disease.

Global, regional, and national total burden related to hepatitis B in children and adolescents from 1990 to 2021

BackgroundHepatitis B remains a significant global health concern with widespread communicability. Nevertheless, data on its burden and trends in children and adolescents were limited. We aim to evaluate the global, regional, and national trends of total burden related to hepatitis B in children and adolescents aged 0–19 years from 1990 to 2021.MethodsThe age-standardized incidence, prevalence, mortality, and disability-adjusted life years (DALYs) were calculated by the Global Burden of Disease (GBD) study from 1990 to 2021. These indicators were stratified by sex, age, socio-demographic index (SDI), and disease stage. We calculated the correlation between them and SDI. The temporal trends were examined using the annual average percentage change (AAPC) and joinpoint regression.ResultsThe global age-standardized incidence of hepatitis B in children and adolescents decreased from 1385.20 per 100,000 population in 1990 to 418.68 per 100,000 population in 2021, with an AAPC of -3.76%. Similarly, age-standardized DALYs decreased from 70.78 per 100,000 population to 36.31 per 100,000 population, with an AAPC of -2.13%. The age-standardized prevalence (AAPC − 3.53%) and mortality (AAPC − 2.09%) of hepatitis B also decreased significantly. From 1990 to 2021, the age-standardized incidence and prevalence among males exhibited a higher trend compared to females, although both declined over time. These two indicators also decreased across all age subgroups, with consistently higher rates observed in the 15–19 age group compared to other age groups. The burden of hepatitis B demonstrated a notable reduction in countries with high-middle SDI, while it was highest in countries with low SDI. In 2021, Central sub-Saharan Africa and West sub-Saharan Africa reported the highest age-standardized incidence. For age-standardized DALYs, South Asia was the only region to experience an increase (AAPC 1.09%), while East Asia showed the largest decline (AAPC − 7.58%). Alcohol and drug use remained important risk factors for DALYs among people aged 15–19 years. Furthermore, the impact of drug use on disease burden was increasing, particularly in high-SDI countries.ConclusionsThe global burden and trends of hepatitis B decreased significantly in children and adolescents, exhibiting regional and national variations. Management of alcohol and drug use remains a major challenge for people aged 15–19 years.

Primary and residual cardiometabolic risk factors among young adults in a Russian city

BackgroundCardiovascular diseases are a leading cause of mortality and a significant contributor to temporary and permanent disabilities worldwide. This study aimed to investigate the burden of primary and residual cardiometabolic risk factors in a sample of young adults in the Russian city of Kazan.MethodsThis case-control study used the Cardiometabolic Disease Staging (CMDS) classification system, which has been validated in several countries. The study included 191 individuals aged 25–44 years who met the inclusion criteria but did not meet any exclusion criteria. Data collection involved a patient card with questions from the World Health Organization’s STEPS instrument, face-to-face patient interviews, and a physical examination. Anthropometric assessments included height, weight, and waist circumference measurements. Body composition was evaluated using bioelectrical impedance measurements. Patients also underwent in-depth laboratory biochemical analyses.ResultsThe study cohort was comprised of 97 females (50.8%) and 94 males (49.2%). The median age of participants was 35.00 years [IQR: 30.00–39.00]. The study cohort showed an increase in all anthropometric parameters, with abdominal obesity and overweight reaching 100% in the CMDS 3. Apart from atherogenic lipids and raised blood pressure, other risk factors that precipitate residual risk and were not part of CMDS, such as insulin levels, insulin resistance, leptin values, and hyperuricemia, increased as CMDS levels increased.ConclusionsThe prevalence of cardiometabolic risk factors was high in young adults in Kazan. This study highlights the need for the early identification and management of cardiometabolic risk factors in young adults to prevent the development of cardiovascular diseases later in life.

Neuroleptic malignant syndrome in Huntington disease.

Despite the wide use of dopamine receptor blocking agents (DRBAs) in Huntington disease (HD), neuroleptic malignant syndrome (NMS) is rarely described in this population. The aim of this study was to assess NMS prevalence in a large cohort of HD patients and explore the main associated risk factors. In 2023, an HD patient was admitted to our neurology department due to NMS. Starting from the case description, we performed a narrative review of the literature of NMS cases in HD, reviewed data from the fifth dataset of the Enroll-HD (a longitudinal, observational, global study of families with HD) study (PDS5) selecting HD patients treated with DRBAs and/or tetrabenazine (TBZ) who presented at least one of the core symptoms of NMS (rigidity and hyperthermia), and collected data to investigate prevalence of NMS and identify risk factors. In the Enroll-HD PDS5 dataset, we identified 5108 of 11,569 HD patients who were undergoing DRBA and/or TBZ treatment. Only one patient, a Caucasian man of 46 years, undergoing clozapine and valproate treatment, had a registered diagnosis of NMS. NMS in HD patients is seldom described. This could be due to an underestimation of this condition. There are no available objective NMS diagnostic criteria at present, and the existence of atypical forms of NMS further complicates diagnosis. Advanced disease stage, rigid-akinetic phenotype, abrupt therapy changes, polytherapy, and dehydration are key risk factors, most of which are preventable through awareness and caution in managing medications in the HD population.
