Background/aims: In France, geographic access to medical care may affect the diagnosis of hepatitis C. The aims of this study were to compare the detection rates of hepatitis C in urban and rural areas after adjusting for distance to medical care, and evaluating the impact of the place of residence on patients' clinical characteristics.
Methods: Between 1994 and 2001, 1938 newly detected cases were recorded in a French population of 1,005,817 inhabitants. Age and sex-adjusted detection rates for 10(5) inhabitants were estimated for urban and rural areas and for classes of distance to the nearest practitioner.
Results: Detection rates were lower in rural than in urban areas [14.1, (95CI: 12.5-15.7) versus 24.7, (95CI: 23.5-26.0)] and decreased as the distance to the general practitioner increased [27.0, (95CI: 25.5-28.4) versus 13.7, (95CI: 12.1-15.3) for a cutoff value of 1.5 km]. In multivariate analyses, detection rates were only influenced by the distance to general practitioner. Hepatocellular carcinoma at diagnosis was more frequent among rural than among urban patients (adjusted OR = 2.28, 95CI: 0.97-5.39, P = 0.059).
Conclusions: A poorer geographic access to care explained the lower detection of hepatitis C in rural areas. Hepatocellular carcinoma was more frequent in rural patients. It may result from later detection and/or involvement of environmental factors on hepatocarcinogenesis.

Assessing modified HEART scores with high-sensitivity troponin for low-risk chest pain in the emergency department.

The accuracy of using HEART (history, electrocardiogram, age, risk factors, and troponin) scores with high-sensitivity cardiac troponin (hs-cTn) to risk stratify emergency department (ED) chest pain patients remains uncertain. We aim to compare the performance accuracy of determining major adverse cardiac event (MACE) among three modified HEART (mHEART) scores with the use of hs-cTn to risk stratify ED chest pain patients. This retrospective single-center observational study included ED patients with suspected acute coronary syndrome who had HEAR scores calculated and at least one hs-cTnI result.

Background: Self-reported mental stress is not consistently recognized as a risk factor for stroke. This prompted development of a novel algorithm for stress-phenotype indices to quantify chronic stress prevalence in relation to a modified stroke risk score in a South African cohort. The algorithm is based on biomarkers adrenocorticotrophic hormone, high-density lipoprotein cholesterol, high-sensitive cardiac-troponin-T, and diastolic blood pressure which exemplifies the stress-ischemic-phenotype index.

Objective: To evaluate the toxic effects of the agent Relatox on mature outbred rats and mice in an acute experiment in comparison with the registered analogue Dysport.
Material And Methods: Based on the aim of experiment, the acute toxic effects of Relatox and Dysport were assessed on two animal species: rats and mice at intraperitoneal and intramuscular administration at dose levels that made it possible to calculate the toxicological parameter values (initially 10-150 U/kg with subsequent usage of additional doses 20 U/kg to 300 U/kg depending on the agent and route of administration). The LD values and other acute toxic parameters were calculated using probit analysis.
Role of PCBP2 in regulating nanovesicles loaded with curcumin to mitigate neuroferroptosis in neural damage caused by heat stroke.

Key Laboratory of Special Environmental Medicine of Xinjiang, General Hospital of Xinjiang Military Command, No. 359, Youhao North Road, Urumqi, Xinjiang, China.
Objective: This study aims to elucidate the mechanisms by which nanovesicles (NVs) transport curcumin(CUR) across the blood-brain barrier to treat hypothalamic neural damage induced by heat stroke by regulating the expression of poly(c)-binding protein 2 (PCBP2).
Methods: Initially, NVs were prepared from macrophages using a continuous extrusion method. Subsequently, CUR was loaded into NVs using sonication, yielding engineered cell membrane Nanovesicles loaded with curcumin (NVs-CUR), which were characterized and subjected to in vitro and in vivo tracking analysis.

Background: This study aimed to investigate the potential utility of Epithelial-mesenchymal transition (EMT) signaling cell detection in the early diagnosis of cervical lesions.
Methods: Enrichment of cervical epithelial cells was carried out using a calibrated membrane with 8-μm diameter pores. RNA-in situ hybridization (RNA-ISH) was employed to detect and characterize EMT cells utilizing specific EMT markers.
