RESUMO

Growing evidences showed that heavy metals exposure may be associated with metabolic diseases. Nevertheless, the mechanism underlying arsenic (As) exposure and metabolic syndrome (MetS) risk has not been fully elucidated. So we aimed to prospectively investigate the role of serum uric acid (SUA) on the association between blood As exposure and incident MetS. A sample of 1045 older participants in a community in China was analyzed. We determined As at baseline and SUA concentration at follow-up in the Yiwu Elderly Cohort. MetS events were defined according to the criteria of the International Diabetes Federation (IDF). Generalized linear model with log-binominal regression model was applied to estimate the association of As with incident MetS. To investigate the role of SUA in the association between As and MetS, a mediation analysis was conducted. In the fully adjusted log-binominal model, per interquartile range increment of As, the risk of MetS increased 1.25-fold. Compared with the lowest quartile of As, the adjusted relative risk (RR) of MetS in the highest quartile was 1.42 (95% confidence interval, CI: 1.03, 2.00). Additionally, blood As was positively associated with SUA, while SUA had significant association with MetS risk. Further mediation analysis demonstrated that the association of As and MetS risk was mediated by SUA, with the proportion of 15.7%. Our study found higher As was remarkably associated with the elevated risk of MetS in the Chinese older adults population. Mediation analysis indicated that SUA might be a mediator in the association between As exposure and MetS.

RESUMO

Allergies play a pivotal role in the daily practice of ENT specialists. Allergic symptoms induced by inhalant allergens are widespread in the population and can manifest through a wide range of symptoms, including rhinorrhea, sneezing, conjunctival redness, cough and dyspnea. Inconsistent diagnosis and treatment of allergic conditions can lead to reduced quality of life, decreased work performance, and socioeconomically significant secondary diseases. In addition to the medical history, the skin prick test and serological IgE diagnostics are the most important diagnostic procedure for detecting type-I allergies. To clarify clinical relevance, molecular diagnostics and nasal provocation testing may be employed. The key to effective treatment lies in a comprehensive allergological diagnosis coupled with a detailed patient history. General treatment recommendations such as allergen avoidance and nasal irrigation should complement pharmacological therapy. In the treatment of allergic rhinitis topical steroids are first line treatment options. The primary goal of treatment is symptom control, and if control is insufficient, causal therapy through specific allergen immunotherapy is recommended. Challenges in the ENT clinic involve selecting the necessary diagnostics and appropriate, effective treatments. Hence, using diagnostic and treatment algorithms, as well as standardized patient history questionnaires, can serve as invaluable tools in daily patient interactions, especially considering limited time availability.

RESUMO

Objective: To explore the distribution of allergen-specific IgE (sIgE) for children with atopic dermatitis in Tianjin City and provide the evidences of clinical diagnosis and treatment. Methods: A retrospective cross-sectional study was conducted to analyze the children who were suspected of atopic dermatitis and tested for serum sIgE in the Tianjin Children's Hospital from March 2021 to February 2023. Using first detection results only, a total of 1 841 serum samples were tested for twenty common allergens. The method was the enzyme-linked immune capture assay. The allergen epidemiological characteristics were statistically analyzed by Chi square test based on the children's characteristics and factors such as different sexes, ages and seasons by the mass data. Results: Among the 1 841 cases, the results showed that 1 247 (67.73%) were sensitized to at least 1 allergen-sIgE, comprising to 49.86% (918/1 841) to food allergen-sIgE and 47.96% (883/1 841) to aeroallergen-sIgE. The top three food allergens-sIgE were egg 32.10% (591/1 841), milk 25.91% (477/1 841) and wheat flour 14.61% (269/1 841); the top three positive rates of aeroallergens-sIgE were house dust 24.33% (448/1 841), alternaria 20.59% (379/1 841) and dermatophagoides farinae 14.83% (273/1 841). The positive rates of food allergens-sIgE were the highest in the 1-3 years old group (64.11%, 434/677) (χ2=122.854, P<0.001), while the positive rates of aeroallergens-sIgE were higher in the 11-14 years old group (71.26%, 62/87) (χ2=134.968, P<0.001). No seasonal difference was revealed in the overall positive rate of food allergen-sIgE and aeroallergen-sIgE (χ2=4.047, P=0.256; χ2=7.549, P=0.056). The positive rates of soybean-sIgE and milk-sIgE were the highest in summer (χ2=11.329, P=0.010; χ2=28.720, P<0.001), whereas alternaria-sIgE and mugwort-sIgE were the highest in summer and autumn, respectively (χ2=8.462, P=0.037; χ2=10.641, P=0.014). Among the 1 841 cases, 32.21% were sensitized to three or more allergens-sIgE. The sIgE concentration levels of egg, milk and house dust were mainly level 1 to 2, and the proportions of level 3 and above were all under 15%; although the positive rates of crab, shrimp, and peanut were low, the proportions of grade 3 and above were all beyond 30%. Children sensitized to alternaria, dermatophagoides farinae, mugwort, and cat dander had higher sIgE concentration levels, which were 68.07%, 49.45%, 56.57% and 47.83% respectively. Conclusions: This study can reflect the epidemic characteristics of allergen-sIgE in children with atopic dermatitis in Tianjin region to a certain extent. Allergen-sIgE positivity in patients differed by age, and there were seasonal differences and grade distribution differences in the positive rates of some allergens-sIgE. It is necessary to reasonably avoid the high-risk allergens according to the epidemiological characteristics and clinical symptoms, which provide valuable information for the prevention, diagnosis and treatment of atopic dermatitis.

RESUMO

Objective: To explore the impact of whole blood organophosphate esters (OPEs) flame retardant exposure on thyroid function-related hormones in healthy older adults. Methods: In this panel study, five repeated population-based epidemiological surveys and biological sample collection were conducted from September 2018 to January 2019, with 76 healthy older adults aged 60-69 years in the Dianliu Community of Jinan, Shandong Province. Information on the sociodemographic characteristics, diet, and health status of the respondents was systematically gathered through questionnaires and physical examinations. Fasting venous blood was collected to determine the levels of OPEs, thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4). A linear mixed-effects model was used to analyze the impact of OPEs exposure on thyroid function-related hormones in healthy older adults. Results: Each of the 76 subjects participated in at least two follow-up visits, resulting in a total of 350 person visits. The age of the study participants was (65.07±2.76) years, with 38 participants of both sexes. A total of eight OPEs were included with a detection rate exceeding 50%, and the M (Q1, Q3) for ∑OPEs was 3.85 (2.33, 5.74) ng/ml, with alkyl-OPEs being the major type of OPEs with an M (Q1, Q3) of 1.27 (0.64, 2.50) ng/ml. The M (Q1, Q3) for TSH, T3, and T4 was 3.74 (2.55, 5.69) µIU/ml, 1.32 (1.10, 1.60) ng/ml, and 45.04 (36.96, 53.27) ng/ml, respectively. Linear mixed-effects model showed that TSH was significantly decreased by 9.93% (95%CI:-15.17%, -4.36%) and 11.14% (95%CI:-15.94%, -6.06%) in older adults for each quartile level increase in TnBP and TEHP exposures, respectively. Gender-stratified analysis indicated that TEHP exposure was negatively associated with TSH levels in male older adults, whereas a decrease in TSH levels among female older adults was associated with TnBP exposure. Conclusion: Exposure to whole blood OPEs is associated with decreased TSH levels among healthy older adults, with notable gender differences.

RESUMO

This study was to investigate the relationship between spring pollen distribution concentration, species and the detection results of air-borne pollen allergens in Taiyuan City, Shanxi Province during March to May 2022 and March to May 2023.A retrospective study was conducted in the Otorhinolaryngology Head and Neck Surgery Clinic of the First Hospital of Shanxi Medical University.Pollen particles will be monitored by gravity sedimentation method on the roof of the outpatient department of the First Hospital of Shanxi Medical University in downtown Taiyuan from March to May 2022-2023, and pollen species and quantity will be observed and recorded under an optical microscope.The air-borne pollen allergen detection results of all allergic rhinitis patients in the otolaryngology Head and Neck surgery Department of the First Hospital of Shanxi Medical University were extracted from the relevant outpatient system. SPSS software and Pearson correlation analysis were used to compare the correlation between the allergens and the dominant air-borne pollen monitoring results. Results are as follows: (1)A total of 18 species of spring pollen in Taiyuan City were monitored in 2022-2023, with 101 177.5 grains, and the dominant airborne pollen was poplar (16.69%) and pine (29.06%) pollen. The pollen of poplar (11.96%), elm (7.89%) and cypress (8.68%) were dominant in early spring; Pine (25.16%) pollen predominated in late spring. The two peaks of pollen dispersal in Taiyuan were in late March (15 479 grains) and early and mid May (15 094/15 343 grains).(2) The positive rates of allergens in serum specific IgE detection were: wormwood (46%, 248/541 cases), tree combination (26%, 143/541 cases), ragweed (19%, 101/541 cases), humulus scandens (9%, 49/541 cases).(3)There was a linear positive correlation between the positive rate of air-borne pollen allergens in allergic rhinitis patients in the Department of Otolaryngology Head and Neck Surgery in the First Hospital of Shanxi Medical University and the dominant air-borne pollen concentration in the same period (P<0.05, r=0.999). In conclusion, two spring pollen dispersal peaks were formed in late March and early to mid May in Taiyuan City, and the dominant air-borne pollens were poplar and pine pollens. The positive rate of air borne pollen allergen sIgE showed that wormwood allergy was the highest.There was a positive correlation between the concentration of air-borne pollen and the positive rate of air-borne pollen allergens in patients with allergic rhinitis in the Department of otorhinolaryngology and head and neck surgery in Taiyuan in 2022 and 2023.The monitoring of pollen distribution in spring can provide an important scientific basis for clinical workers to formulate prevention and treatment plans for patients with allergic rhinitis in the season, and provide data reference for the epidemiological investigation of allergic diseases in Taiyuan in the future.

RESUMO

Objective: To explore the relationship between serum 1, 5-dehydratoglucitol (1, 5-AG) level and insulin resistance, microvascular complications in patients with type 2 diabetes mellitus (T2DM). Methods: The clinical data of 836 patients with T2DM admitted to the Changsha Central Hospital Affiliated to University of South China from May to December 2023 were retrospectively and cross-sectionally analyzed. Serum 1, 5-AG levels were detected by pyranose oxidase method. According to the microvascular complications (diabetic peripheral neuropathy, diabetic nephropathy, diabetic retinopathy), the patients were divided into simple group (no microvascular complications, n=490), complication group 1 (1 microvascular complications, n=217), and complication group 2 (2 or more microvascular complications, n=129). The relationship between serum 1, 5-AG level and the related indicators of insulin resistance in T2DM patients were explored by Spearman correlation analysis, and the influencing factors of microvascular complications in T2DM patients were explored by multiple ordered logistic regression analysis. Results: The levels of FBG(fasting blood glucose) [(7.37±0.56) mmol/L], FINS(fasting insulin) [(11.34±1.86) mU/L] and HOMA-IR(homeostatic model assessment of insulin resistance) (0.96±0.31) in simple group were lower than those in complication group 1 [(8.37±1.02) mmol/L, (16.26±2.32) mU/L, (1.32±0.41)], complication group 2 [(10.25±2.13) mmol/L, (18.53±2.67) mU/L, (1.54±0.44)], and FBG, FINS and HOMA-IR in complication group 1 were lower than those in complication group 2, and the differences were statistically significant (F=537.470, 791.690, 136.340, P<0.001). Serum 1, 5-AG level in simple group [77.16 (16.30, 128.07) µg/ml] was higher than that in complication group 1 [51.05 (14.67, 63.18) µg/ml] and complication group 2 [30.42 (12.53, 47.26) µg/ml], and the serum level of 1, 5-AG in complication group 1 was higher than that in complication group 2, and the difference was statistically significant (H=210.020, P<0.001). The results of Spearman correlation analysis showed that serum 1, 5-AG level was negatively correlated with FBG, FINS and HOMA-IR in T2DM patients (r=-0.431, -0.372, -0.546, P<0.001). The results of multiple ordered logistic regression analysis showed that Longer duration of diabetes (OR=2.261, 95%CI: 1.564-3.269), increased HbA1c (OR=2.040, 95%CI: 1.456-2.858), and increased HOMA-IR (OR=2.158, 95%CI: 1.484-3.137) and decreased 1, 5-AG (OR=2.512, 95%CI: 1.691-3.732) were independent risk factors for microvascular complications in T2DM patients (P<0.05). The results of ROC curve analysis showed that the area under the curve of serum 1, 5-AG in the identification of one microvascular complication was 0.763 (95%CI: 0.731-0.795), and the area under the curve of serum 1, 5-AG in the identification of two or more microvascular complications was 0.730 (95%CI: 0.692-0.767). Conclusion: Serum 1, 5-AG level is negatively correlated with insulin resistance in T2DM patients. Low serum 1, 5-AG level may be an independent risk factor for microvascular complications in T2DM patients.

RESUMO

Here, we reported a case of delayed diagnosis of allergic bronchopulmonary aspergillosis (ABPA) with low serum IgE and normal Aspergillus fumigatus-specific IgE levels. During the course of the disease, the patient (female, 55 years old) had imaging manifestation of mass shadow and significant elevation of carcinoembryonic antigen, leading to suspicion of a lung tumor. Later, transbronchial lung biopsy tissue culture showed Aspergillus fumigatus. Combined with the history, clinical characteristics and imaging, she was diagnosed with allergic bronchopulmonary aspergillosis combined with invasive pulmonary aspergillosis. As the diagnostic criteria for ABPA do not cover all patients with ABPA, in rare cases where immunological evidence is insufficient, a combination of clinical and imaging features is required for early diagnosis and treatment.

RESUMO

Objective: To investigate the clinical features of acute macular neuroretinopathy (AMN) following coronavirus disease 2019 (COVID-19). Methods: This retrospective case series study included 15 patients (28 eyes) diagnosed with AMN at the Department of Ophthalmology, Peking University Third Hospital, from November 2022 to January 2023. The AMN group comprised 4 males and 11 females, with a mean age of (31.36±8.08) years. A control group of 15 individuals [5 males, 10 females; mean age (33.20±5.10) years] who had COVID-19 but did not develop AMN was also included. Data collected for all patients included best-corrected visual acuity (BCVA), slit-lamp examination, dilated fundus examination, color fundus photography, fluorescein fundus angiography (FFA), and optical coherence tomography (OCT) results. Serum cytokine levels, including interleukins (ILs), interferons (IFNs), and tumor necrosis factor-alpha (TNF-α), were measured for both groups. Results: Among the 28 eyes, severe vision loss (BCVA≤0.3) was observed in 3 eyes (10.7%), moderate vision loss (BCVA>0.3 and≤0.5) in 2 eyes (13.3%), and mild vision loss (BCVA>0.5 and≤1.0) in 23 eyes (82.1%). OCT findings in all 28 eyes revealed hyperreflectivity of the outer nuclear layer and disruption of outer retinal structure. Additionally, 3 eyes (10.7%) exhibited cotton wool spots in the posterior pole, 2 eyes (7.1%) showed mild cystoid macular edema with intraretinal hyperreflective dots, and 1 eye (3.6%) presented with paracentral acute middle maculopathy. FFA indicated retinal vasculitis in 2 cases (4 eyes, 14.3%). Serum levels of IL-4, IL-5, IFN-α, and IFN-γ were significantly higher in the AMN group compared to the control group: IL-4 [4.49 (3.66, 6.08) vs. 1.40 (0.62, 1.68) pg/ml], IL-5 [7.34 (5.04, 14.06) vs. 0.17 (0.11, 1.86) pg/ml], IFN-α [8.42 (6.31, 14.89) vs. 0.50 (0.30, 0.83) pg/ml], and IFN-γ [17.93 (12.75, 32.44) vs. 7.43 (0.00, 14.74) pg/ml], with all differences being statistically significant (all P<0.05). Conclusion: AMN following COVID-19 can present with wedge-shaped dark red lesions in the macular area, often accompanied by cotton wool spots and retinal vasculitis. Additionally, there is a significant elevation in various inflammatory cytokines in the serum.

RESUMO

BACKGROUND The prevalence of metabolic (dysfunction)-associated fatty liver disease (MAFLD) increases together with the epidemic of childhood obesity. An important mechanism in the phenomenon appears to be insulin resistance (IR), the assessment of which in children is problematic. The homeostatic model assessment of IR (HOMA-IR), commonly used for this, is not standardized and appears not to correlate with IR in the pediatric population. Therefore, our study aimed to evaluate potential substitute indices of IR, including the triglyceride-glucose index (TyG), triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C), modified TyG indices: TyG-waist circumference (TyG-WC) and TyG-body mass index (TyG-BMI) as surrogate markers of MAFLD in obese children suspected to have liver disease. MATERIAL AND METHODS The retrospective study included 264 obese children admitted to the Department to diagnose suspected liver disease. MAFLD was diagnosed according to the International Expert Consensus Statement. Anthropometric measurements and laboratory tests were made and the indices were calculated. Receiver operating characteristics analysis was performed to calculate the power of the indices. RESULTS MAFLD was diagnosed in 184 patients (70%). Obese children with MAFLD showed significantly higher activity of liver enzymes and concentration of total cholesterol, TG, WC, and waist-to-hip ratio compared to non-hepatopathic obese controls (n=80). The most important indices in identifying MAFLD were: TyG (AUC=0.641, p<0.001, cut-off =8.41, sensitivity=57.4%, specificity=68.8%), and TG/HDL-C (AUC=0.638, p<0.001, cut-off=2.5, sensitivity=48.6%, specificity=76.3%). TyG-BMI and HOMA-IR were not useful predictors. CONCLUSIONS TyG and TG/HDL-C can be considered as potential surrogate biomarkers in predicting MAFLD in obese children.

RESUMO

OBJECTIVES: Electrocardiogram (ECG) and measurement of plasma brain natriuretic peptides (BNP) are established markers of right ventricular dysfunction (RVD) in the setting of acute pulmonary embolism (PE) but their value at long-term follow-up is largely unknown. The purpose of this prospective study was to determine the prevalence of ECG abnormalities, describe levels of N-terminal proBNP (NT-proBNP), and establish their association with dyspnea at long-term follow-up after PE. DESIGN: All Swedish patients diagnosed with acute PE in 2005 (n = 5793) were identified through the Swedish National Patient Registry. Surviving patients in 2007 (n = 3510) were invited to participate. Of these, 2105 subjects responded to a questionnaire about dyspnea and comorbidities. Subjects with dyspnea or risk factors for development of chronic thromboembolic pulmonary hypertension were included in the study in a secondary step, which involved collection of blood samples and ECG registration. RESULTS: Altogether 49.3% had a completely normal ECG. The remaining participants had a variety of abnormalities, 7.2% had atrial fibrillation/flutter (AF). ECG with any sign of RVD was found in 7.2% of subjects. Right bundle branch block was the most common RVD sign with a prevalence of 6.4%. An abnormal ECG was associated with dyspnea. AF was associated with dyspnea, whereas ECG signs of RVD were not. 61.2% of subjects had NT-proBNP levels above clinical cut-off (>125 ng/L). The degree of dyspnea did not associate independently with NT-proBNP levels. CONCLUSIONS: We conclude that the value of ECG and NT-proBNP in long term follow-up after PE lies mostly in differential diagnostics.

RESUMO

Although the deleterious impact of chemotherapy regimen used to treat women of reproductive age with breast cancer on ovarian reserve has been extensively studied, hardly anything has been reported on the effect of these protocols on theca cell function and ovarian androgen secretion. The aim of this prospective multicentric cohort study was to describe serum levels of total testosterone and androstenedione during chemotherapy and 24-month follow-up in 250 patients <40 years treated for breast cancer. Mean basal levels of androstenedione and total testosterone at diagnosis were 1.68 ng/mL and 0.20 ng/mL respectively. No correlation with age was found. Serum levels of androstenedione and total testosterone rapidly decreased after chemotherapy completion, before slowly increasing and almost returning to basal levels in all patients during 2-year follow-up. In conclusion our study demonstrates a chemotherapy-induced alteration of ovarian thecal function, resulting in a significant decrease in serum androgen levels. This alteration of theca cell function adds to the well-known alteration of granulosa cell function, resulting in a global, but partly transient, ovarian failure in young women treated for breast cancer.

RESUMO

BACKGROUND: Hematologic and blood biochemical values are key tools for assessing primate health. A long-term behavioral study of howler monkeys at a single site (La Pacífica, Guanacaste, Costa Rica), afforded the opportunity to develop baseline values for a large group of animals, evaluating differences between adult males and females and comparing to a report in the same population two decades later. METHODS: In 1998, 64 free-ranging mantled howler monkeys were anesthetized and sampled for hematologic and biochemical analysis. RESULTS: Blood analysis is reported for 29 adult females, 9 juvenile females, 19 adult males and 3 juvenile males. Four adults were excluded due to external injury or disease. There were few significant differences between adult females, juvenile females, and adult males. CONCLUSIONS: Baseline blood parameters are useful for determining normal values for howler monkey populations. The values for total protein, blood urea nitrogen, glucose, liver enzymes and potassium differed from a later study in 2019 may indicate changes that are influencing howler monkey health.

RESUMO

BACKGROUND: The objective of this study was to investigate the clinical relevance of anti-prothrombin antibodies (aPT) and anti-phosphatidylserine/prothrombin antibodies (aPS/PT) in relation to pregnancy outcomes and coagulation parameters, as well as immune markers. METHODS: We retrospectively analyzed 477 pregnant women with experienced at least one spontaneous miscarriage who were tested for aPT and aPS/PT antibodies, and compared their clinical characteristics, coagulation indicators, immune biomarkers, and pregnancy outcomes to assess the diagnostic accuracy of these antibodies. RESULTS: We found that the aPT IgG and the aPS/PT IgM were independently associated with increased risk of pregnancy loss, with odds ratios (ORs) of 1.055 (95% confidence interval [CI]: 1.009-1.103, p = 0.017) and 1.041 (95% CI: 1.015-1.067, p = 0.002), respectively. Moreover, we found that the aPS/PT IgM had a higher diagnostic performance than the aPT IgG, as indicated by the AUC of 0.663 and 0.593, respectively. The pregnancy loss rate was positively correlated with the level of aPS/PT IgM, while the aPT IgG is not. We also found that in the pregnancy loss group, aPT IgG showed negative correlations with prothrombin time (PT); aPS/PT IgM showed positive correlations with aPS/PT IgG. However, none of aPT IgG, aPT IgM, aPS/PT IgM, or aPS/PT IgG was related to other adverse pregnancy outcomes, such as preterm delivery, fetal growth restriction (FGR), or preeclampsia (PE). CONCLUSION: Our findings suggest that aPT IgG and aPS/PT IgM are independent risk factors for pregnancy loss, especially aPS/PT IgM, which has a positive linear correlation with pregnancy loss.

RESUMO

PROBLEM: This study aimed to evaluate the predictive value of delta neutrophil index (DNI), a peripheral blood parameter, on perinatal outcomes in pregnant women with systemic lupus erythematosus (SLE). METHOD OF STUDY: One hundred eighty-one participants, 78 pregnant women with SLE, and 103 healthy pregnant women were included in this retrospective study. Peripheral blood parameters including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and DNI taken in the first trimester were compared between groups. RESULTS: NLR, PLR, and DNI were significantly higher in the SLE group (p = 0.027, p = 0.007, p = 0.0001, respectively). The same parameters were not found to be significant in determining disease activity in pregnant women with SLE (p > 0.05). When the predictive value of DNI for SGA in pregnancies with SLE was evaluated by receiver operating characteristic curve (ROC), the area under the ROC curve (AUC) was 0.666 (95% CI; 0.544-0.788, p = 0.018) with 84.6% sensitivity, 53.8% specificity, 56.0% PPV, and 78.1% NPV at a cut-off value of 0.16. The predictive value of DNI according to ROC for stillbirth in pregnancies with SLE was AUC 0.731 (95% CI: 0.539-0.923, p = 0.019) with a cut-off value of 0.17, sensitivity of 90%, specificity of 51.5%, PPV of 58.5%, and NPV of 87.2%. CONCLUSIONS: Although DNI's prediction of SGA and stillbirth in pregnant women with SLE is encouraging, it needs more evidence from prospective studies with larger series.

RESUMO

Several auto-immune diseases have been linked to vitamin D deficiency as a contributing environmental factor. Its pleiotropic effects on the immune system, especially its essential role in maintaining immune tolerance, make the vitamin D pathway of great interest. In this study, we focused on Pemphigus foliaceous (PF) in Tunisian population. we aimed to quantify the Serum 25[OH]D levels using chemiluminescence assay and to analyze the differential expression of the VDR, CYP27B1 and CYP24A1 genes in the circulating blood cells and lesional skin tissue of PF patients using Q-PCR. A genetic explanation was then sought to explore any direct relationship between tag polymorphisms and the inherited features of PF. Results confirmed a vitamin D hypovitaminosis in Tunisian PF patients. Interestingly, a differential gene expression correlated to the disease stratification was noted. Indeed, at the systemic level, an upregulation of VDR and CYP27B1 genes was observed in healthy controls compared to PF patients. Notably, in lesional skin tissue, the clinical and serological remission phase was correlated with high transcriptional levels of the VDR gene and conversely a drop in expression of the CYP24A1 gene. Genetic analysis indicated the involvement of the most appealing polymorphisms, rs2228570 and poly (A) microsatellite, in PF etiopathogenesis. Indeed, CAC13 haplotype was associated with a higher risk of PF development. Our findings suggest that alterations in the vitamin D-VDR pathway may influence PF physiopathology, making this pathway a potential target for pharmacological modulation, especially for cortico-resistant PF patients.

RESUMO

PURPOSE: Despite the importance of self-monitoring blood glucose (SMBG) for management of diabetes mellitus (DM), frequent blood sampling is discouraged by bleeding risk due to dual-antiplatelet agent therapy (DAPT) or thrombocytopenia. METHODS: We compared the bleeding time (BT) of sampling by using a laser-lancing-device (LMT-1000) and a conventional lancet in patients with DM and thrombocytopenia or patients undergoing DAPT. BT was measured using the Duke method, and pain and satisfaction scores were assessed using numeric rating scale (NRS) and visual analog scale (VAS). The consistency in the values of glucose and glycated-hemoglobin (HbA1c) sampled using the LMT-1000 or lancet were compared. RESULTS: The BT of sampling with the LMT-1000 was shorter than that with the lancet in patients with thrombocytopenia (60s vs. 85s, P = 0.024). The NRS was lower and the VAS was higher in laser-applied-sampling than lancet-applied sampling in the DAPT-user group (NRS: 1 vs. 2, P = 0.010; VAS: 7 vs. 6, P = 0.003), whereas the group with thrombocytopenia only showed improvement in the VAS score (8 vs. 7, P = 0.049). Glucose and HbA1c sampled by the LMT-1000 and lancet were significantly correlated in both the DAPT-user and the thrombocytopenia groups. CONCLUSION: The LMT-1000 can promote SMBG by shortening BT in subject with thrombocytopenia and by increasing satisfaction score, as well as by showing reliable glucose and HbA1c value.

RESUMO

The objective of the study was to evaluate the effect of the inclusion of cocoa bran in the diet of lambs and its effect on reproductive parameters. For this, 40 lambs were randomly assigned to four treatments, and including 0, 10, 20 and 30% levels of cocoa bran in the concentrate. Blood was collected to measure cholesterol and testosterone and semen for physical and morphological evaluation; testicular biometry and morphometry were also evaluated. There was significant difference (P < 0.05) in body weight and tubulosomatic index between the lambs in the control treatment and those in the 30% cocoa bran treatment. There was no difference in testicular biometry, physical and morphological parameters of fresh semen, testicular morphometry, and volumetric ratio between lambs in all the treatments (P < 0.05). In addition, there was no difference in plasma cholesterol or testosterone concentration (P > 0.05). Thus, it is possible to include up to 30% of cocoa bran in diet without affecting the reproductive parameters of lambs.

RESUMO

Objective: To identify the relationship between thyroid autoimmunity and antinuclear antibody (ANA) prevalence in Chinese pregnant women. Methods: The study involved 1923 first-trimester women who were measured for thyroid stimulating hormone (TSH) level, thyroid autoantibodies (thyroperoxidase antibody [TPOAb] and thyroglobulin antibody [TgAb]) and ANA titer. Social demographic data were collected through standardized questionnaires. Results: In this study, 23.3% of pregnant women tested positive for TPOAb and 9.9% tested positive for TgAb. Women with a positive ANA were more likely to be TPOAb-positive or TgAb-positive than women with a negative ANA (adjusted odds ratio [AOR] 1.96, 95% confidence interval [CI] 1.47-2.62 for TPOAb [+]; AOR 3.12, 95% CI 2.18-4.48 for TgAb[+]). In addition, ANA titers were closely associated with thyroid autoimmunity. Women with an ANA titer of >1:320 had a significant higher risk of being TPOAb positive or TgAb positive (AOR 4.49, 95% CI 1.48-13.66 for TPOAb [+]; AOR 5.51, 95% CI 1.65-18.49 for TgAb [+]). The higher the ANA titer, the greater the risk of developing thyroid autoimmunity, especially for those with a high ANA titer. Conclusions: ANA positivity is strongly correlated with thyroid autoimmunity. Further study is warranted to clarify the causal relationship between thyroid autoimmunity and ANA in pregnant women.This research is essential to evaluate and predict the risk of co-existing autoimmune disorders,leading to improved care for pregnancy and neonatal health.

RESUMO

Background: 177Lu-oxodotreotide peptide receptor therapy (LuPRRT) is an efficient treatment for midgut neuroendocrine tumors (NETs) of variable radiological response. Several clinical, biological, and imaging parameters may be used to establish a relative disease prognosis but none is able to predict early efficacy or toxicities. We investigated expression levels for mRNA and miRNA involved in radiosensitivity and tumor progression searching for correlations related to patient outcome during LuPRRT therapy. Methods: Thirty-five patients received LuPRRT for G1/G2 midgut NETs between May 2019 and September 2021. Peripheral blood samples were collected prior to irradiation, before and 48 h after the second and the fourth LuPRRT, and at 6-month follow-up. Multiple regression analyses and Pearson correlations were performed to identify the miRNA/mRNA signature that will best predict response to LuPRRT. Results: Focusing on four mRNAs and three miRNAs, we identified a miRNA/mRNA signature enabling the early identification of responders to LuPRRT with significant reduced miRNA/mRNA expression after the first LuPRRT administration for patients with progressive disease at 1 year (p < 0.001). The relevance of this signature was reinforced by studying its evolution up to 6 months post-LuPRRT. Moreover, nadir absolute lymphocyte count within the first 2 months after the first LuPRRT administration was significantly related to low miRNA/mRNA expression level (p < 0.05) for patients with progressive disease. Conclusion: We present a pilot study exploring a miRNA/mRNA signature that correlates with early hematologic toxicity and therapeutic response 12 months following LuPRRT. This signature will be tested prospectively in a larger series of patients.

RESUMO

Purpose: The aim of this study was to evaluate the associations of thyroid autoimmunity (TAI) with the number of oocytes retrieved (NOR), fertilization rate (FR), and embryo quality (EQ) in euthyroid women with infertility and diminished ovarian reserve (DOR). Methods: This retrospective cohort study involved 1,172 euthyroid women aged 20-40 years with infertility and DOR who underwent an oocyte retrieval cycle. TAI was diagnosed in the presence of serum thyroperoxidase antibody (TPOAb) concentrations higher than 34 IU/ml and/or serum thyroglobulin antibody (TgAb) concentrations exceeding 115.0 IU/ml. Among these women, 147 patients with TAI were classified as the TAI-positive group, while 1,025 patients without TAI were classified as the TAI-negative group. Using generalized linear models (GLMs) adjusted for confounding factors, we evaluated the associations of TAI and the serum TPOAb and TgAb concentrations and NOR, FR, and EQ in this study's subjects. The TPOAb and TGAb values were subjected to log10 transformation to reduce skewness. Logistic regression models were used to estimate the effects of TPOAb and TgAb concentrations on the probabilities of achieving a high NOR (≥7) and high FR (>60%). Results: For the whole study population, women with TAI had a significantly lower NOR and poorer EQ than women without TAI (P < 0.001 for both). Interestingly, in the TSH ≤2.5 subgroup, the TAI-positive group also had a significantly lower NOR and poorer EQ than the TAI-negative group (P < 0.001 for both). Furthermore, negative associations were observed between log10(TPOAb) concentrations and NOR and the number of high-quality embryos and available embryos (P < 0.05 for all). The log10(TgAb) concentrations were inversely associated with NOR and the number of high-quality embryos (P < 0.05 for all). In the regression analysis, the log10(TPOAb) concentrations had lower probabilities of achieving a high NOR [adjusted odds ratio (aOR): 0.56; 95% confidence interval (95% CI) 0.37, 0.85; P = 0.007]. Conclusions: TAI and higher TPOAb and TgAb concentrations were shown to be associated with reductions in the NOR and EQ in the study population. Our findings provide further evidence to support systematic screening and treatment for TAI in euthyroid women with infertility and DOR.
