Objectives: To assess the effects of a gluten-free diet on bone structure in children with celiac disease using fractal analysis on panoramic radiographs. Method and materials: A total of 49 patients with celiac disease aged 6 to 13 years, separated into two groups as previously and newly diagnosed, and a control group of 32 healthy individuals were evaluated. In previously and newly diagnosed patients with celiac disease, body mass index Z-scores were calculated, calcium, alkaline phosphatase, vitamin D3, and parathormone levels were measured, and bone mineral density Z-scores were obtained from dual energy x-ray absorptiometry. In all patients, the fractal dimensions of the right and left temporomandibular condyles were evaluated with the fractal analysis method on panoramic radiographs. Results: The mean values of serum biomarker levels and the body mass index and bone mineral density Z-scores for both celiac groups were within the normal reference range. No statistically significant difference was determined between right and left condyle fractal dimensions values in the three groups examined. In terms of both right and left condyle fractal dimensions values, there was a statistically significant difference between groups. The highest fractal dimensions values were determined in the previously diagnosed group. Conclusions: Differences in fractal dimensions values were observed among patients with celiac disease following the gluten-free diet. Utilizing fractal analysis on panoramic radiographs can prove valuable for dental practitioners in evaluating bone mineral density due to its cost-effect iveness, easy accessibility, and reduced radiation exposure for patients, enabling them to provide comprehensive oral health care and potential early interventions for patients with celiac disease.

Blood properties influence aerobic exercise performance. While vascular volumes and hemoglobin mass (Hbmass) are elevated in trained individuals, evidence of sex differences in vascular volumes is equivocal due to inadequate matching of aerobic fitness between males and females. This cross-sectional study aimed to compare hematological values normalized to body mass (BM) and fat-free mass (FFM) between males (n = 45) and females (n = 34) matched for aerobic fitness (V̇O2max) normalized to FFM (mL∙kg FFM−1∙min−1). Data included body composition measured by dual-energy X-ray absorptiometry (DXA), V̇O2max from an incremental test, and hematological values derived from a CO rebreathe test. Fat mass was unrelated to blood volume (BV; R2 = 0.02, P = 0.26) and Hbmass (R2 = 0.03, P = 0.16), while FFM was the strongest predictor of both (R2 = 0.75 and R2 = 0.83, respectively, P < 0.001). Females exhibited higher FFM-normalized BV (+4%, P < 0.05) and plasma volume (PV) (+14%, P < 0.001) and lower red blood cell volume (RBCV) (−8%, P < 0.001) and Hbmass (−8%, P < 0.001) compared to males. Positive correlations between aerobic fitness and relative Hbmass and BV were observed in both sexes when normalized to BM and FFM (0.48 < r < 0.71; P < 0.003). Stepwise multiple regression models, including FFM, V̇O2max, height, and [Hb], provided accurate predictions of Hbmass (R2 = 0.91) and BV (R2 = 0.85). Overall, sex differences persist in relative Hbmass, BV, PV, and RBCV after matching of aerobic fitness, though relative BV and PV were greater in females. These findings suggest sex-specific strategies in oxygen delivery and/or extraction, and they underscore the importance of carefully selecting normalization practices when assessing sex-based differences in hematological variables.

Background & Objective: In 2020, breast cancer claimed the lives of approximately 684,996 women worldwide. The use of cancer biomarkers has greatly improved the effectiveness of treatment and early detection. The present study was conducted aimed to identify the role of testin as a potential biomarker in women with breast cancer. Materials & Methods: In this cross-sectional study, 60 women with breast cancer participated by providing serum samples for measuring testin concentrations. Additionally, a control group of 20 healthy individuals was selected. The testin protein concentration was detected using the serum ELISA method. Results: A significant difference was observed between the age groups of patients and healthy women. The majority of women with breast cancer were in their thirties to sixties. On the other hand, there were fewer breast cancer cases recorded in the twenties, with only 1 (1.7%) case out of the total study population of 60 (100%). This difference was found to be statistically significant (P=0.01). The study found that there was no significant difference in the concentration of testin among women with breast cancer who were newly diagnosed compared to those who had received different numbers of treatment doses (1, 3, 5, 7 doses). Also, the results indicated a significant increase in testin concentration among women with breast cancer compare with healthy women. Conclusion: The present study discovered that breast cancer patients have higher levels of testin compared to the healthy women. There is a growing body of evidence suggesting that testin contributes to the development of breast cancer, making it an appealing protein to focus on for cancer treatment. [ABSTRACT FROM AUTHOR]

Background: Tetrapleura tetraptera, a widely used medicinal plant in West Africa, has been traditionally employed for various ailments. Despite its folkloric significance, scientific validation of its safety and potential neuroactive properties remains limited. Objectives: This study aimed to investigate the acute and subchronic toxicity of Tetrapleura tetraptera hot water extract (HWETTF) in rats and to elucidate its phytochemical composition. Methods: Acute oral toxicity was assessed in mice using the OECD guideline 423, while a 14-day repeat-dose toxicity study was conducted in rats. The phytochemical analysis included HPLC, FT-IR, and GC–MS. Results: HWETTF exhibited no significant toxicity in acute or subchronic studies, even at high doses. Phytochemical analysis revealed a diverse array of compounds, including those with potential GABAergic and CNS depressant activities. Conclusion: Tetrapleura tetraptera demonstrated a favourable safety profile in rodents and possesses a rich phytochemical composition. Further research is warranted to explore its potential neuroactive properties and develop therapeutic applications. [ABSTRACT FROM AUTHOR]

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) represents a significant global health burden without established curative therapies. Early detection and preventive strategies are crucial for effective MASLD management. This study aimed to develop and validate machine-learning (ML) algorithms for accurate MASLD screening in a geographically diverse, large-scale population. Methods: Data from the prospective Fasa Cohort Study, initiated in rural Fars province, Iran (March 2014), were employed for this purpose. The required data were collected using blood tests, questionnaires, liver ultrasonography, and physical examinations. A two-step approach identified key predictors from over 100 variables: (1) statistical selection using mean decrease Gini in random forest and (2) incorporation of clinical expertise for alignment with known MASLD risk factors. The hold-out validation approach (with a 70/30 train/validation split) was utilized, along with 5-fold cross-validation on the validation set. Logistic regression, Naïve Bayes, support vector machine, and light gradient-boosting machine (LightGBM) algorithms were compared for model construction with the same input variables based on area under the receiver operating characteristic curve (AUC), sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy. Results: A total of 6,180 adults (52.7% female) were included in the study, categorized into 4816 non-MASLD and 1364 MASLD cases with a mean age (± standard deviation [SD]) of 48.12 (± 9.61) and 49.47 (± 9.15) years, respectively. Logistic regression outperformed other ML algorithms, achieving an accuracy of 0.88 (95% confidence interval [CI]: 0.86-0.89) and an AUC of 0.92 (95% CI: 0.90-0.93). Among more than 100 variables, the key predictors included waist circumference, body mass index (BMI), hip circumference, wrist circumference, alanine aminotransferase levels, cholesterol, glucose, high-density lipoprotein, and blood pressure. Conclusion: Integration of ML in MASLD management holds significant promise, particularly in resource-limited rural settings. Additionally, the relative importance assigned to each predictor, particularly prominent contributors such as waist circumference and BMI, offers valuable insights into MASLD prevention, diagnosis, and treatment strategies.

Background: Low-carbohydrate diets (LCD) are popular for weight loss but lack evidence about micronutrient sufficiency in real-life use. This study assessed the intake and biochemical status of selected micronutrients in people voluntarily following LCDs. Methods: A cross-sectional study was conducted (2018-20) among 98 adults recruited as self-reporting either LCD (n = 49) or diets not restricting carbohydrates (controls; n = 49). Diets were assessed using the 130-item EPIC-Norfolk food-frequency questionnaire. Red-blood-cell thiamine diphosphate (TDP) was measured for thiamine status using HPLC. Plasma magnesium, zinc, copper, and selenium were measured using inductively coupled plasma mass spectrometry. Between-group biomarker comparisons were conducted using ANCOVA and adjusted for age, sex, body mass index (BMI), and diabetes status. Results: LCD-followers (26% male, median age 36 years, median BMI 24.2 kg/m2) reported adhering to LCDs for a median duration of 9 months (IQR 4–36). The most followed LCD type was 'their own variations of LCD' (30%), followed by ketogenic (23%), 'palaeolithic' (15%), and Atkins diets (8%). Among controls, 41% were male (median age 27 years, median BMI 23 kg/m2). Median macronutrient intakes for LCD vs control groups were carbohydrate 16%Energy (E) vs. 50%E; protein 25%E vs. 19%E; and fat 55%E vs 34%E (saturated fat 18%E vs. 11%E). Two-thirds of LCD followers (32/49) and half of the controls (24/49) reported some use of dietary supplements (p = 0.19). Among LCD-followers, assessing from food data only, 21 (43%) failed to meet the reference nutrient intake (RNI) for thiamine (vs.14% controls, p = 0.002). When thiamine from supplementation (single- or multivitamin) was included, there appeared to be no difference in thiamine intake between groups. Still, red-blood-cell TDP was lower in LCD-followers than controls (407 ± 91 vs. 633 ± 234 ng/gHb, p < 0.001). Three LCD-followers were thiamine-deficient (RBC thiamine < 275 ng/gHb) vs. one control. There were no significant differences in dietary intakes or plasma concentrations of magnesium, zinc, copper, and selenium between groups. Conclusions: Following LCDs is associated with lower thiamine intake and TDP status than diets without carbohydrate restriction, incompletely corrected by supplement use. These data, coupled with a lack of RCT evidence on body weight control, do not support recommending LCDs for weight management without appropriate guidance and diet supplementation.

Purpose: Our study aimed to explore the efficacy of Bifidobacterium breve 207-1 on specific neurotransmitters and hormones and the ability to regulate lifestyle behaviors in healthy adults. Methods: In total, 120 healthy adults with high mental stress, overweight, insomnia, and constipation were randomly assigned to receive low-dose B. breve 207-1 (LD, n = 40), high-dose B. breve 207-1 (HD, n = 40), or placebo (n = 40) for 28 days. Fecal and blood samples were collected and questionnaires were answered before and after the trial. Neurotransmitters and serum hormones were detected using enzyme-linked immunosorbent assay. The gut microbiota composition was assessed using 16 S rRNA sequencing. Short–chain fatty acids (SCFAs) concentrations were determined via gas chromatography–mass spectrometry (GC–MS). Results: The primary outcome of our study was changes in mental wellness, including neurotransmitters, the hypothalamic–pituitary–adrena (HPA) axis hormones, and the psychological scales. The results showed that γ-aminobutyric acid (GABA) increased significantly and the HPA axis hormones were suppressed overall in the probiotic groups while 5-hydroxytryptamine (5-HT) did not change significantly. However, there was no significant change in mood scale scores. The secondary outcome focused on the ability of 207-1 to regulate the body and lifestyle of healthy adults (e.g., sleep, diet, exercise, etc.). The PSQI scores in the probiotics groups significantly decreased, indicating improved sleep quality. Meanwhile, the probiotic groups had a slight increase in exercise consumption while dietary intake stabilized. By physical examination, the participants showed weight loss although no statistically significant difference was observed between the groups. Then, validated by gut microbiota, changes in the gut microbiota were observed under the effective intervention of 207-1 while short-chain fatty acids (SCFAs) increased in the LD group, particularly acetic and propionic acids. There was a slight decrease in alpha–diversity in the HD group. Conclusion: Bifidobacterium breve 207-1 entered the organism and affected neurotransmitter and the HPA axis hormone levels via the microbiome-gut-brain axis. Meanwhile, 207-1 supplementation improved daily lifestyle behaviors in healthy adults, which may in turn lead to changes in their bodies (e.g. weight and lipid metabolism). However, this study did not find significant mood-modulating efficacy. The mechanism of the overall study is unclear, but we hypothesize that SCFAs may be the key pathway, and more experiments are needed for validation in the future. Trial registration: This trial was retrospectively registered in the Chinese Clinical Trial Registry under the accession number ChiCTR2300069453 on March 16, 2023. [ABSTRACT FROM AUTHOR]

Nesfatin‐1 and ghrelin, initially recognised as hormones involved in regulating energy, have emerged as crucial players with vital functions in various human body systems. In this study, we conducted a comparative assessment of nesfatin‐1 and ghrelin responses in individuals experiencing metabolic stress due to diabetes, those with depressive diabetes characterised by both metabolic and mental stress, and healthy controls. We collected blood samples from a total of 90 participants, consisting of 30 people with type II diabetes mellitus (DM), 30 people with type II DM and major depressive disorders, and 30 healthy individuals. Diabetes was diagnosed based on glycated haemoglobin (HbA1c) levels, while depression was assessed using DSM‐V criteria. Insulin resistance (HOMA‐IR) was calculated, and serum ghrelin and nesfatin‐1 levels were measured using ELISA kits. We observed statistically significant decreases in nesfatin‐1 and ghrelin levels in the diabetic group (p < 0.0001). However, in the depressive diabetic group, nesfatin‐1 levels increased significantly, while ghrelin levels decreased further. The nesfatin‐1 to ghrelin ratio decreased in the diabetic group but increased significantly in the depressive diabetic group (p < 0.0001). Nesfatin‐1 and ghrelin hormones exhibit parallel impacts in response to metabolic stress, but nesfatin‐1 demonstrates contrasting actions compared to ghrelin when mental stress is added to metabolic stress. The findings of this study suggest that nesfatin‐1 and ghrelin hormones may play active roles as protective, prognostic, and even etiological factors in various stress situations, particularly those involving mental stress, in addition to their known functions in regulating energy.

Background and Aims: The natural history of untreated patients with type 1 Gaucher disease (GD1) is not well documented, and there is controversy over when and how to treat such patients, especially if they are only mildly symptomatic. Treatment of GD1 is inconvenient, very costly, and may result in undesirable side effects. We documented the clinical history of 31 untreated patients with GD1 followed in our clinic for 4–26 (median 15) years. Methods: This was a retrospective, observational study of the progress of untreated adult patients with GD1 followed by blood tests (haemoglobin, platelet counts, ferritin and chitotriosidase), organ volumes (spleen and liver), bone manifestations (through magnetic resonance imaging and dual X‐ray absorptiometry scans) and neurological and quality of life issues. Statistical analyses were performed with the use of the Student paired t test and the modified Wald test for 95% confidence intervals. Results: We found that the above parameters remained stable in most patients over a period of 4–26 (median 15) years. Five patients progressed from normal bone density to osteopenia and two from osteopenia to osteofibrosis; six were peri‐ or post‐menopausal females. The DS‐3 was stable over time. Only four of the 31 patients were started on enzyme or substrate reduction therapy. Conclusions: Our results demonstrate that many patients with GD1, provided with close follow‐up by a specialist centre, can be followed for many years without requiring treatment and with no or minimal worsening of their GD1 manifestations.

Context Histidine-containing dipeptides (carnosine, anserine, beta-alanine and others) are found in human muscle tissue and other organs like the brain. Data in rodents and humans indicate that administration of exogenous carnosine improved cognitive performance. However, RCTs results vary. Objectives To perform a systematic review and meta-analysis of randomized controlled trials (RCTs) of histidine-containing dipeptide (HCD) supplementation on cognitive performance in humans to assess its utility as a cognitive stabiliser. Data Sources OVID Medline, Medline, EBM Reviews, Embase, and Cumulative Index to Nursing and Allied Health Literature databases from 1/1/1965 to 1/6/2022 for all RCT of HCDs were searched. Data Extraction 2653 abstracts were screened, identifying 94 full-text articles which were assessed for eligibility. Ten articles reporting the use of HCD supplementation were meta-analysed. Data Analysis The random effects model has been applied using the DerSimonian-Laird method. HCD treatment significantly increased performance on Wechsler Memory Scale (WMS) −2 Delayed recall (Weighted mean difference (WMD) (95% CI (CI)) = 1.5 (0.6, 2.5), P < .01). Treatment with HCDs had no effect on Alzheimer's Disease Assessment Scale-Cognitive (WMD (95% CI) = −0.2 (−1.1, 0.7), P = .65, I2 = 0%), Mini-Mental State Examination (WMD (95% CI) = 0.7 (−0.2, 1.5), P = .14, I2 = 42%), The Wechsler Adult Intelligence Scale (WAIS) Digit span Backward (WMD (95% CI) = 0.1 (−0.3, 0.5), P = .51, I2 = 0%), WAIS digit span Forward (WMD (95% CI) = 0.0 (−0.3, 0.4), P = .85, I2 = 33%) and the WMS-1 Immediate recall (WMD (95% CI) = .7 (−.2, 1.5), P = .11, I2 = 0%). The effect on delayed recall remained in subgroup meta-analysis performed on studies of patients without mild cognitive impairment (MCI), and in those without MCI where average age in the study was above 65. Conclusion HCD, supplementation improved scores on the Delayed recall examination, a neuropsychological test affected early in Alzheimer's disease. Further studies are needed in people with early cognitive impairment with longer follow-up duration and standardization of carnosine doses to delineate the true effect.

Objectives: The purpose of this study was to compare and contrast Kawasaki disease (KD) with multisystem inflammatory syndrome in children (MIS-C) during the SARS-CoV-2 pandemic. Methods: A retrospective analysis of the medical records of patients diagnosed with KD and MIS-C at a single institution from July 2020 to November 2021 was performed. Results: The study included 39 MIS-C patients (84.6% male) with a median age of 138 months and 17 KD patients (58.8% male) with a median age of 36 months. The MIS-C patients were older (p < 0.001) and had prolonged hospitalizations (p = 0.023), elevated neutrophil counts (p < 0.001), C-reactive protein (p < 0.001), procalcitonin (p < 0.001), interleukin-6 (p < 0.014), ferritin (p < 0.001), fibrinogen (p < 0.001), troponin I (p = 0.001), NT-proBNP (p < 0.001), and D-dimer levels (p < 0.001). There were more cases of hypotension (p = 0.024), decreased left ventricular function (p = 0.023), and a greater need for corticosteroids (p < 0.001), enoxaparin (p = 0.045), and therapeutic plasma exchange (p < 0.001). Kawasaki disease patients had a greater incidence of rash (p < 0.001), changes in oral mucosa (p < 0.001), conjunctival injection (p < 0.001), extremity changes (p < 0.001), and cervical lymphadenopathy (p < 0.001). They had a longer duration of fever (p < 0.001), elevated white blood cell count (p < 0.001), platelet count (p < 0.001), and alanine aminotransferase level (p < 0.001). The two groups were similar regarding the hemoglobin levels, erythrocyte sedimentation rates, albumin levels, and the frequency of coronary aneurysm, myocarditis, pericarditis, invasive mechanical ventilatory support, and intravenous immunoglobulin treatment. Conclusions: Advanced patient age, a greater presence of gastrointestinal and cardiac findings associated with hypotension, increased NT-proBNP levels, decreased left ventricular function, the use of various treatment modalities, and longer hospital stays suggest MIS-C, whereas prolonged fever and classical clinical features of KD favor KD.

Background: The HIV epidemic in sub-Saharan Africa has a disproportionate gender impact, with women bearing the brunt of the epidemic. South Africa carries the largest share of the global HIV burden, with similar trends seen for women due to unequal socio-cultural and economic status. Objectives: This study aims to understand 30–49 year-old women's barriers and facilitators to accessing HIV services in order to maximize health in resource limited settings and reach women missing from HIV care. Design: Employing a convenience sampling strategy, we recruited, informed, and consented participants at clinics and public areas. Interviews were conducted in respondent's preferred languages, transcribed verbatim, translated into English if needed, and thematically analyzed using grounded theory. Methods: We conducted 81 interviews with women aged 30–49 either missing from care (n = 21), having unknown HIV status (n = 30) or linked to care (n = 30) within two sites: City of Johannesburg district, Gauteng Province and Mopani district, Limpopo Province. Results: Participants missing from care reported negative staff attitudes, queues, family rejection, medication side effects, and painful blood tests as key deterrents. Participants with an unknown status were deterred by fear of being diagnosed as HIV positive and family rejection, which was similar to women missing from care who often dropped out from care due to actual family rejection. Participants linked to care reported that long queues and staff shortages were challenges but stayed in care due to a will to live for themselves and their children, in addition to counselling and feeling emotionally supported. Interestingly, participants missing from care often accessed medication from friends but, similarly to those with unknown status, noted that they would access care if attended to by supportive nurses and by having non-clinical HIV services. Conclusions: The accounts of women in this research highlight significant improvements needed to address inequities in the fight against HIV in South Africa. Additionally, the healthcare service access preferences of women aged 30–49 need to be further explored quantitatively in order to design policy relevant interventions. Plain language summary: Understanding HIV service preferences of South African women 30–49 years old missing from or linked to care: An exploratory study of Gauteng and Limpopo provinces The HIV epidemic in sub-Saharan Africa harms women more than men. South Africa carries the largest share of the global HIV burden, with similar trends seen for women. This study aims to understand 30–49 year-old women's ability to access HIV services in order to reach women missing from HIV care. We conducted 81 interviews with women aged 30–49 either missing from care (n = 21), having unknown status (n = 30) or linked to care (n = 30) within two sites: City of Johannesburg district, Gauteng Province and Mopani district, Limpopo Province. We recruited, informed, and consented participants at clinics and public areas. Interviews were conducted in respondent's preferred languages, transcribed, and translated into English for analysis. Participants missing from care reported negative staff attitudes, queues, family rejection, medication side effects and painful blood tests as key deterrents. Participants with an unknown status were deterred by fear of being diagnosed as HIV positive and family rejection, which was similar to women missing from care who often dropped out from care due to family rejection.

Background: Patients with gastric cancer (GC) who underwent radical surgery require long-term follow-up (usually 5 years). The purpose of this study was to explore individualized follow-up strategies for patients with GC. Methods: This is a retrospective cohort study that established a clinicopathologic database of patients who underwent gastrectomy from January 2010 to December 2020 at Ningbo No. 2 Hospital. Follow-up was performed until March 2023. The rate of new-onset recurrence of patients with GC was explored annually according to different pTNM stages, defining a recurrence rate of less than 1% as adequate follow-up time. Results: Of the 1606 patients who were eligible, the total number of patients who completed the 5- and 10-year follow-up was 1107 and 586, respectively. A total of 444 cases were diagnosed with recurrence. The recurrence rate for stage IA patients was consistently less than 1% during the follow-up time. The adequate follow-up time (the rate of new-onset recurrence less than 1%) was 5 years for stage IB and IIA patients, and 8 years for stage IIB and IIIA patients, respectively. In contrast, stage IIIB patients were always at risk of recurrence during the follow-up time (>1%). Time to a new recurrence rate for stage IIIC patients was 6 years. Conclusion: Among patients who underwent radical gastrectomy, the rate of new-onset recurrence varied among patients with different pTNM stages. This study suggests that the follow-up of GC can be individualized and refer to pTNM stage. [ABSTRACT FROM AUTHOR]

BACKGROUND: Chronic stroke can impair cardiopulmonary function, mobility, and daily activities. This study assessed the impact of robot-assisted gait training (RAGT) on such impairments. OBJECTIVE: To investigate the effects of robot-assisted gait training on cardiopulmonary function, walking ability, lower extremity function and strength, activities of daily living (ADLs), and blood test results among individuals with chronic stroke. METHODS: A multicenter, prospective, single-blinded, randomized controlled trial with 22 chronic stroke participants compared RAGT against a control exercise regimen. RAGT involved three days weekly sessions of high-intensity interval training for 8 weeks (24 sessions) with a Morning Walk® device. The control group also performed home exercises. (24 sessions) Measures included VO2max, Functional Ambulatory Category, 2-minute walk test, 10-meter walk test, Motricity Index-Lower, Korean version of the Fugl-Meyer Assessment Scale, Modified Barthel Index, Berg Balance Scale, muscle strength, InBody body composition, and blood tests (cholesterol, lipid, glucose). RESULTS: RAGT significantly improved VO2max, gait, balance, and lower limb strength compared with controls, with significant improvements in 2-minute walk test, 10-meter walk test, Motricity Index-Lower, and Fugl-Meyer Assessment outcomes. No changes were seen in muscle mass or blood markers. CONCLUSION: RAGT enhances cardiopulmonary function and ambulatory capacity in chronic stroke patients, underscoring its potential in stroke rehabilitation. [ABSTRACT FROM AUTHOR]

Objective: To verify the administration of a new nano delivery system coated with Tirofiban on preventing early thrombosis in vein graft. Methods: Forty New Zealand white rabbits were randomly divided into five groups with eight rabbits in each group. The rabbits of all groups underwent jugular vein transplantation, except group I with only neck opening and closing operation. Vein grafts of group II were preprocessed by intravenous injection of normal saline; group III were preprocessed by tirofiban alone; group IV were preprocessed by unloaded nanoparticles of PLGA-PEG; group V were preprocessed by PLGA-PEG coated with tirofiban. Coagulation and platelet function of peripheral and vein graft blood were detected at 1, 2, 4, 12 h and 1, 3, 7, 10, 14 days after operation. Patency rate of vein graft and blood flow index were measured by vascular ultrasound at third, seventh, 10th, and 14th days after operation; two rabbits in each group were randomly sacrificed at the corresponding time of detection. Pathological differences of vein grafts were observed by HE stainin. Results: The patency rate of vein grafts in group V was significantly higher than that in group II to IV. The platelet and platelet aggregation rate in group V were inhibited in vein graft blood significantly. The post-operative PT and APTT in vein graft blood in group V were increased obviously while the FBG, D-dimer and FDP were significantly inhibited. Except group I, the lumen loss rate of vein grafts in group V was significantly lower than that in other groups, and vein graft blood in group V had a significant lower expression of platelet P-selectin and GP IIb/IIIa receptor than that in other groups. Conclusion: This study proves that PEG-PLGA coated with tirofiban can effectively prevent early vein graft stenosis from thrombosis by inhibition of platelet function, coagulation function.

Understanding the biological mechanisms behind multimorbidity patterns in adolescence is important as they may act as intermediary risk factor for long-term health. We aimed to explore relationship between prenatal exposures and adolescent's psycho-cardiometabolic intermediary traits mediated through epigenetic biomarkers, using structural equation modeling (SEM). We used data from mother–child dyads from pregnancy and adolescents at 16–17 years from two prospective cohorts: Northern Finland Birth Cohort 1986 (NFBC1986) and Raine Study from Australia. Factor analysis was applied to generate two different latent factor structures: (a) prenatal exposures and (b) adolescence psycho-cardiometabolic intermediary traits. Furthermore, three types of epigenetic biomarkers were included: (1) DNA methylation score for maternal smoking during pregnancy (DNAmMSS), (2) DNAm age estimate PhenoAge and (3) DNAm estimate for telomere length (DNAmTL). Similar factor structure was observed between both cohorts yielding three prenatal factors, namely BMI (Body Mass Index), SOP (Socio-Obstetric-Profile), and Lifestyle, and four adolescent factors: Anthropometric, Insulin-Triglycerides, Blood Pressure, and Mental health. In the SEM pathways, stronger direct effects of F1prenatal-BMI (NFBC1986 = β: 0.27; Raine = β: 0.39) and F2prenatal-SOP (β: −0.11) factors were observed on adolescent psycho-cardiometabolic multimorbidity. We observed an indirect effect of prenatal latent factors through epigenetic markers on a psycho-cardiometabolic multimorbidity factor in Raine study (P < 0.05). The present study exemplifies an evidence-based approach in two different birth cohorts to demonstrate similar composite structure of prenatal exposures and psycho-cardiometabolic traits (despite cultural, social, and genetic differences) and a common plausible pathway between them through underlying epigenetic markers.

Purpose: Dyslipidemia is a major health issue worldwide. There is growing interest in understanding the potential role of kimchi consumption on serum lipid profiles. However, there are limited epidemiological studies available on this topic. Therefore, this study aims to investigate the association between kimchi intake and serum lipid profiles. Methods: We conducted an epidemiological study on participants (aged 40–69 years old) selected from the Health Examinees (HEXA) cohort study (n = 61,761). Four types of kimchi, including Baechu kimchi (cabbage kimchi), Kkakdugi (radish kimchi), Nabak kimchi/Dongchimi (a type of water kimchi made with fermented vegetables), and other kimchi, were assessed by a 106-food item semi-quantitative validated food frequency questionnaire (FFQ). Each kimchi intake is the average value calculated from the FFQ of the baseline and follow-up surveys. Fasting blood data were obtained at baseline and follow-up visits. Linear regression was used to examine the relationship between the intake of kimchi and the change in serum lipid profiles. Results: The mean years between the baseline survey and a follow-up survey was 4.97 years. In this study, compared to the lowest category (< 1 serving/day), Baechu kimchi intake (2− < 3 servings/day) had more negative correlations with the change in values of total cholesterol (β: −1.600, 95% confidence interval [CI, −2.744, −0.456]), triglycerides (β: −3.372, 95% CI [−5.414, −1.330]), and low-density lipoprotein cholesterol (β: −1.155, 95% CI [−2.214, −0.095]) in women. In men, Baechu kimchi intake (2− < 3 servings/day) had a more positive correlation associated with the changes in values of high-density lipoprotein cholesterol (β: 0.049, 95% CI [0.031, 0.907]) compared to the lowest intake category (< 1 serving/day). Conclusions: Among Korean adults, consumption of kimchi, particularly Baechu kimchi, was found to be associated with improvements in serum lipid profiles. Further studies are required to conduct additional interventions to confirm the association between kimchi and serum lipid profiles. [ABSTRACT FROM AUTHOR]

Although transcatheter aortic valve replacement (TAVR) is safe and effective, mortality and bleeding events post procedure are important. The present study investigated the changes in hematologic parameters to evaluate whether they predict mortality or major bleeding. We enrolled 248 consecutive patients (44.8% male; mean age 79.0 ± 6.4 years) undergoing TAVR. In addition to demographic and clinical examination, blood parameters were recorded before TAVR, at discharge, 1 month and 1 year. Hemoglobin levels before TAVR 12.1 ± 1.8 g/dL, 10.8 ± 1.7 g/dL at discharge, 11.7 ± 1.7 g/dL at first month, 11.8 ± 1.4 g/dL at first year (Hemoglobin values compared with pre-TAVR, P <.001, P =.019, P =.047, respectively). Mean platelet volume (MPV) before TAVR 8.72 ± 1.71 fL, 8.16 ± 1.46 fL at discharge, 8.09 ± 1.44 fL at first month, 7.94 ± 1.18 fL at first year (MPV values compared with pre-TAVR, P <.001, P <.001, P <.001, respectively). Other hematologic parameters were also evaluated. Hemoglobin, platelet count, MPV, and red cell distribution width before the procedure, at discharge, and at the first year did not predict mortality and major bleeding in receiver operating characteristic analysis. After multivariate Cox regression analysis, hematologic parameters were not independent predictors of in-hospital mortality, major bleeding, and death at 1 year after TAVR. [ABSTRACT FROM AUTHOR]

The study aimed to evaluate the feasibility of implementing lifestyle interventions in primary care settings with hypertensive patients and their effect on blood pressure, body composition, cardiometabolic markers, and antihypertensive drug use. Sixty participants diagnosed with stage 1 hypertension were randomly assigned to 4 groups: (1) Standard medical care (control), (2) Physical activity protocol, (3) Dietary Approach to Stop Hypertension (DASH) diet, and (4) Combination of physical activity protocol and DASH diet. Participants received counseling from family physicians, nurses, kinesiologists, and registered dietitians. Various assessments were conducted before (T0) and after (T6) the interventions, including 24-h ambulatory blood pressure monitoring, blood and urine tests, anthropometric measurements, computed tomography to measure adipose tissue, submaximal exercise test to estimate maximal oxygen consumption and health questionnaires. Fifty-one (51) participants (51/57, 89%) completed the program. All interventions reduced blood pressure indices between T0 and T6, except the combined interventions group. Body composition and cardiometabolic parameters were improved in all groups, except for the control group. In total, 28% of participants (7/23) reduced or stopped their antihypertensive medications at T6. The results suggest that structured lifestyle interventions are feasible in primary care and improve blood pressure and cardiometabolic parameters in patients with stage 1 hypertension.

Background: The objective of this study is to analyze the transplacental transmission of SARS-CoV-2 antibodies, their persistence in newborns, the factors that may influence this transmission, and the protection these antibodies confer over time. Methods: This prospective cohort was conducted in a tertiary pediatric hospital in the Barcelona Metropolitan Region, Spain. It included neonates born to mothers who had SARS-CoV-2 infection during pregnancy or delivery between August 2020 and January 2022. We followed the recruited children for at least six months, and blood tests were performed to determine the presence of SARS-CoV-2 antibodies. Results: A total of 101 children were recruited. Among the serologies performed on children under three months of age, 44/82 were positive (53.7%). Newborns whose mothers presented more severe disease exhibited higher seropositivity odds (coefficient 9.747; p = 0.002). There were increased preterm deliveries when maternal infection occurred closer to the time of delivery. No severe SARS-CoV-2 infections were detected in children during the follow-up. Conclusions: Slightly more than half of the SARS-CoV-2 serologies performed in the first three months were positive. This appears to confer protection during early childhood. The severity of maternal infection is the most significant factor influencing the transmission of antibodies in children born to unvaccinated mothers. [ABSTRACT FROM AUTHOR]

Objective: Patients with mild oral and maxillofacial space infection (OMSI) usually need only antimicrobial therapy. However, surgical intervention is eventually needed after using antibiotics for a period. The objective of this study was to explore the risk factors for drug therapy failure in OMSI. Subjects and methods: A retrospective case‒control study was designed. From August 2020 to September 2022, patients at Shanghai Jiao Tong University Affiliated Ninth People's Hospital who were diagnosed with OMSI were retrospectively reviewed. The outcome variable was surgical intervention after the use of antibiotics. We collected common biological factors, including demographic characteristics, routine blood test results, C-reactive protein (CRP) levels and composite indicators, such as neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR). The χ2 test and binary logistic regression were used to examine the association between biological factors and the outcome variable. Results: Forty-six patients were included in this study. Further surgical intervention was needed in 20 patients (43.5%). The NLR showed a significant association with further surgical drainage (p = 0.01). A binary logistic regression equation was found by using stepwise regression based on the Akaike information criterion (R2 = 0.443), which was associated with sex (odds ratio [OR], 0.216; p = 0.092), NLR (OR, 1.258; p = 0.045), red blood cell (RBC) count (OR, 4.372; p = 0.103) and monocyte (MONO) count (OR, 9.528, p = 0.023). Receiver operating characteristic analysis produced an area under the curve for NLR of 0.725 (p = 0.01) and for the binary logistic regression model of 0.8365 (p < 0.001). Conclusion: Surgical interventions are needed in some mild OMSI patients when antimicrobial therapy fails to stop the formation of abscesses. The binary logistic regression model shows that NLR can be used as an ideal prognostic factor to predict the outcome of antimicrobial therapy and the possibility of requiring surgical intervention. Statement of clinical relevance: Using simple, inexpensive, and easily achieved biological parameters (such as routine blood test results) and composite indicators calculated by them (such as NLR) to predict whether surgical intervention is needed in the future provides a reference for clinical doctors and enables more cost-effective and efficient diagnosis and treatment.

Background: Exposure to a high-altitude environment is a risk factor for cerebral venous thrombosis (CVT) probably due to hypercoagulability. The study aims to explore the unique characteristics of CVT patients in high-altitude areas of China by comparing them with those in plain areas. Methods: We retrospectively included consecutive patients with CVT admitted to Tibet Autonomous Region People's Hospital (altitude 3650 m) and Peking Union Medical College Hospital (altitude 43.5 m) between January 2015 and December 2023. Patients from the plateau and the plain were considered two independent groups in this study. The risk factors, clinical and radiological presentations, treatment, and outcomes were analyzed and compared between the two groups. Results: A total of 169 patients with CVT were included in the study, 48 patients from plateau and 121 patients from plain. The median age was 27 and 34 years old, and women accounted for 66.7% and 54.5% respectively. Headache (91.7% vs. 71.1%, P = 0.004), altered consciousness (31.3% vs. 16.5%, P = 0.033), hemorrhage (41.7% vs. 19.0%, P = 0.002), and venous infarction (50.0% vs. 25.6%, P = 0.002) on imaging were more common in patients from plateau than those from plain. Pregnancy or puerperium was significantly more common in highland patients (25% vs. 5.8%, P < 0.001). The levels of D-Dimer (1.7 vs. 0.8 mg/L FEU, P = 0.01), fibrinogen (3.7 vs. 3.0 g/L, P < 0.001), hemoglobin (157 vs. 129 g/L, P = 0.01), white blood cells (9.6 vs. 7.5*1012/L, P < 0.001) and highly sensitive C-reactive protein (20.2 vs. 3.2 mg/L, P = 0.005) were remarkably higher in highland patients. The percentage of receiving anticoagulant therapy was lower in high-altitude patients (70.8% vs. 93.4%, P < 0.001). Favorable outcome at follow-up was observed in 81.4% of highland patients and 90.7% of lowland patients, with a median follow-up time of 330 days and 703 days respectively. Conclusions: The more severe clinical and imaging manifestations along with prominent inflammatory and hypercoagulable states were observed in plateau CVT patients, probably due to exposure to the hypoxic environment at high altitude. Pregnancy or puerperium were more common in highland patients. The overall prognosis of CVT patients from both groups were favorable. [ABSTRACT FROM AUTHOR]

Background: Dengue fever (DF) is a mosquito‐borne illness with substantial economic and societal impact. Understanding laboratory trends of hospitalized Dominican Republic (DR) pediatric patients could help develop screening procedures in low‐resourced settings. We sought to describe laboratory findings over time in DR children with DF and DF severity from 2018 to 2020. Methods: Clinical information was obtained prospectively from recruited children with DF. Complete blood count (CBC) laboratory measures were assessed across Days 1–10 of fever. Participants were classified as DF‐negative and DF‐positive and grouped by severity. We assessed associations of DF severity with demographics, clinical characteristics, and peripheral blood studies. Using linear mixed‐models, we assessed if hematologic values/trajectories differed by DF status/severity. Results: A total of 597 of 1101 with a DF clinical diagnosis were serologically evaluated, and 574 (471 DF‐positive) met inclusion criteria. In DF, platelet count and hemoglobin were higher on earlier days of fever (p < = 0.0017). Eighty had severe DF. Severe DF risk was associated with thrombocytopenia, intraillness anemia, and leukocytosis, differing by fever day (p < = 0.001). Conclusions: In a pediatric hospitalized DR cohort, we found marked anemia in late stages of severe DF, unlike the typically seen hemoconcentration. These findings, paired with clinical symptom changes over time, may help guide risk‐stratified screenings for resource‐limited settings. [ABSTRACT FROM AUTHOR]

Aims The primary aim of this scoping review was to explore and categorize the medication-related self-care behaviours exhibited by patients with non-valvular atrial fibrillation (NVAF) who are on oral anticoagulant (OAC) therapy. Methods and results A scoping review was performed, and the systematic search of the literature yielded an initial 887 records. After deduplication and screening, 61 studies were included in the analysis, ranging from 2003 to 2023. The studies represented a wide geographical distribution and diverse methodologies. The results identified 16 self-care behaviours: a higher focus of the included literature on self-care monitoring (60.65% of studies), followed by self-care management and self-care maintenance (each 16.39%). These behaviours ranged from regular blood testing to consulting healthcare providers and lifestyle changes. The results also highlighted the relationship between treatment satisfaction, self-efficacy, and adherence. Several studies emphasized the critical role of healthcare providers in influencing medication adherence. Furthermore, patient knowledge, quality of life, and psychological factors were identified as key elements affecting self-care behaviours. Conclusion The review provides a comprehensive landscape of medication-related self-care behaviours among NVAF patients on OAC therapy. It underscores the predominance of self-care monitoring behaviours and the critical roles of healthcare providers, psychological factors, and patient knowledge in influencing these behaviours. The findings also highlight the necessity for an integrated, patient-centred approach to improving self-care and self-management in OAC treatment. Future research should focus on addressing the identified gaps, including the relative lack of studies on lifestyle modification, emotional well-being, and technology-assisted interventions. Registration This review is part of a broader project and is documented at ClinicalTrials.gov : NCT05820854. [ABSTRACT FROM AUTHOR]

Purpose: This retrospective study was conducted to identify factors associated with repeated suicide attempts by analyzing the electronic medical records of suicide attempters who visited emergency medical centers due to drug intoxication. Methods: Data from January 1, 2020 to December 31, 2021 were collected for this study and analyzed using SPSS/WIN 25.0. Results: In this study, the factors affecting repeated suicide attempts among individuals who visited the emergency medical center due to acute drug intoxication were the presence or absence of psychiatric diseases, the season of drug intoxication, and age. In order to identify the factors affecting repeated suicide attempts in those who presented with acute drug intoxication, logistic regression analysis was performed by inputting psychiatric diseases, season of drug intoxication, and age, all of which exhibited significant differences between those who did and did not attempt suicide again. The presence of psychiatric diseases (odds ratio [OR] = 1.99, 95% confidence interval [CI] = 1.04~3.80), intoxication occurring in the fall (vs. spring; OR = 3.35, 95% CI = 1.28~8.75), and age ≥ 65 (vs. those under the age of 18; OR = 12.96, 95% CI = 2.02~83.17). The regression model was found to be statistically significant (F = 30.01, p < .001), and the coefficient of determination of Cox and Snell, which represents the explanatory power of the model, was 12.0%. Conclusion: This study suggests that to prevent repeated suicide attempts, it is necessary to develop a tool to evaluate the risk of suicide, use it to evaluate the risk of suicide, and then manage individuals accordingly.

Introduction: Necrotizing enterocolitis (NEC) is a severe gastrointestinal problem that predominantly affects premature babies. The aim of this retrospective study was to evaluate patients who underwent surgical treatment for NEC and newborns who initially recovered with medical treatment but later developed a stricture and required surgery. Materials and Methods: We analyzed patients diagnosed with NEC between January 2009 and December 2021. Our study included patients who developed strictures after initially receiving medical treatment for NEC and subsequently underwent surgery. Demographic findings, mother's age, gestational weeks, birth weight, type of birth, postnatal age at NEC diagnosis, pH, first C-reactive protein (CRP) after onset of symptoms, leukocytes, hemoglobin and thrombocytes at the onset of NEC, echocardiography results, age at surgery, blood values before surgery, surgery technique, and outcomes were retrospectively analyzed. Results: Out of 40 patients who underwent primary surgery for NEC during the newborn period, 6 patients underwent surgery after initially receiving medical treatment. The female-to-male ratio was 15/31, and the median gestational age was 29 weeks. The median mother's age was 30 years, and the median birth weight was 1097g. The median postnatal age at NEC onset was 6 days (range 2-39). Echocardiography was performed in 43 patients, with 6 showing normal results and 28 having congenital cardiac anomalies. The median surgery day for patients who underwent primary surgery for NEC was 19 days (range 2-90). Ileostomy was performed in 26 patients, colostomy in 8 patients, and ileostomy plus colostomy in 1 patient. Surgery was conducted in 6 out of 392 patients who developed post- NEC strictures after initial medical treatment. Comparison between post-NEC stricture patients and those who underwent surgery for NEC revealed significant differences only in the age at surgery (p=0.024). Conclusion: Patients who clinically experience NEC should be considered for the development of strictures, especially in cases of prolonged feeding intolerance, distention, gastric residual, and rectal bleeding. Therefore, close follow-up and multidisciplinary approaches are crucial, and contrast barium radiography should be the initial diagnostic step. [ABSTRACT FROM AUTHOR]

Current guidelines for prolonged altitude exposure suggest altitude levels ranging from 2000 to 2500 m to optimize an increase in total hemoglobin mass (Hbmass). However, natural low altitude locations (<2000 m) remain popular, highlighting the interest to investigate any possible benefit of low altitude camps for endurance athletes. Ten elite racewalkers (4 women and 6 men) underwent a 4‐week "live high‐train high" (LHTH) camp at an altitude of 1720 m (PIO2 = 121 mmHg; 20.1°C; 67% relative humidity [RH]), followed by a 3‐week tapering phase (20 m; PIO2 = 150 mmHg; 28.3°C; 53% RH) in preparation for the World Athletics Championships (WC). Venous blood samples were withdrawn weekly during the entire observation period. In addition, blood volumes were determined weekly by carbon monoxide rebreathing during altitude exposure and 2 weeks after return to sea level. High‐level performances were achieved at the WC (five placings among the Top 10 WC races and three all‐time career personal bests). A slight but significant increase in absolute (+1.7%, p = 0.03) and relative Hbmass (+2.3%, p = 0.02) was observed after 4‐week LHTH. In addition, as usually observed during LHTH protocols, weekly training distance (+28%, p = 0.02) and duration (+30%, p = 0.04) significantly increased during altitude compared to the pre‐LHTH period. Therefore, although direct causation cannot be inferred, these results suggest that the combination of increased training load at low altitudes with a subsequent tapering period in a warm environment is a suitable competition‐preparation strategy for elite endurance athletes. Highlights: Despite current guidelines for prolonged altitude exposure, natural low altitude locations (<2000 m) remain popular among elite endurance athletes, highlighting the interest to investigate any possible benefit of low altitude camps.This study reports that elite racewalkers achieved a modest but significant increase in Hbmass after a 4‐week LHTH camp at an altitude of 1720 m. Furthermore, this intervention led to performance success at the subsequent World Athletics Championships.The combination of an increased training load while exposed to low altitude is suggested as a valuable competition preparation strategy for elite endurance athletes.

Simple Summary: This study investigated a new blood test (9G testTM Cancer/Lung) for early lung cancer detection. This test measures complexes of autoantibodies with specific lung cancer antigens for CYFRA 21-1 and p53. This study found that the diagnostic performances were significantly better than traditional methods at identifying LC, especially in early stages. The test showed good overall accuracy (AUC of 0.945) and detected early-stage lung cancer with high sensitivity (87.5%). This suggests it could be a valuable tool alongside existing scans like X-rays and LDCT for improving early LC detection. The early detection of lung cancer (LC) improves patient outcomes, but current methods have limitations. Autoantibodies against tumor-associated antigens have potential as early biomarkers. This study evaluated the 9G testTM Cancer/Lung, measuring circulating complexes of two antigen–autoantibody immune complexes (AIC) against their respective free antigens (CYFRA 21-1 and p53) for LC diagnosis. We analyzed 100 LC patients and 119 healthy controls using the 9G testTM Cancer/Lung, quantifying the levels of AICs (CYFRA 21-1-Anti-CYFRA 21-1 autoantibody immune complex (CIC) and p53-Anti-p53 autoantibody immune complex (PIC)), free antigens (CYFRA 21-1 and p53), and ratios of AICs/antigens (LC index). The levels of the CICs and PICs were significantly elevated in LC compared to the controls (p < 0.0062 and p < 0.0026), while free antigens showed no significant difference. The CIC/CYFRA 21-1 and PIC/p53 ratios were also significantly higher in LC (all, p < 0.0001). The LC index, when combining both ratios, exhibited the best diagnostic performance with an area under the curve (AUC) of 0.945, exceeding individual CICs, PICs, and free antigens (AUCs ≤ 0.887). At a cut-off of 3.60, the LC index achieved 81% sensitivity and 95% specificity for LC diagnosis. It detected early-stage (Stage I–II) LC with 87.5% sensitivity, exceeding its performance in advanced stages (72.7%). The LC index showed no significant differences based on age, gender, smoking status (former, current, or never smoker), or pack years smoked. The LC index demonstrates promising potential for early LC diagnosis, exceeding conventional free antigen markers. [ABSTRACT FROM AUTHOR]

To determine the role of platelet counts in the context of the decision to treat patients with non-compounded, non-surgically-treated blunt traumatic brain injury (NCNS-bTBI) with anticoagulants/antiaggregants. A retrospective analysis of 141 anticoagulants/antiaggregants-naïve patients with NCNS-bTBI. Changes in PT-INR and prolonged aPTT were examined and correlated with Marshall and Rotterdam scores, clinical and neuroradiological outcomes. Three groups of platelet counts were identified. Group 1 (83% of patients) had normal platelet counts (150,000–450,000 platelets/mm3) from admission to discharge. Group 2 (13%) developed transient thrombocytopenia (<150,000 platelets/mm3) 2–3 days post-trauma. Group 3 (4%) developed extreme thrombocytosis > 1,000,000/mm3 platelets 6–9 days post-trauma. Neither acute coagulopathy of trauma nor progressive hemorrhagic insults followed NCNS-bTBI. Moreover, while patients with thrombocytosis/extreme thrombocytosis presented with a worse Glasgow coma score (GCS) on admission (8.8 ± 2.9 vs. 13 ± 2, p < 0.01) and had longer hospitalization (13.5 ± 10.4 vs. 4.5 ± 2.1 days), their improvement at discharge was the highest (delta GCS, 4 ± 2.8 vs. 1.2 ± 2.1, p = 0.05). Traumatic subarachnoid hemorrhage was associated with isolated thrombocytosis and 'best improvement.' No thromboembolic or hemorrhagic complications occurred. NCNS-bTBI, thrombocytosis was correlated with better outcomes and was not associated with an increased risk for developing thromboembolism or hemorrhage, precluding the immediate need for any additional antiaggregates.

Approximately 2.2% of Libyans have chronic hepatitis B (CHB) and are at the highest risk of developing end-stage disease complications. Several resource-limited countries, including Libya, may be far from achieving the WHO goal of hepatitis B elimination by 2030 as a result of several testing and linkage to care (LTC) barriers. In Libya, data about the current HBV infection situation is scarce. Therefore, our study aimed to evaluate the trends of HBV in eastern Libya, Tobruk region, and try to identify the region-specific gaps and barriers that could potentially delay the WHO goal of HBV elimination. An eighteen-year retrospective review of records of the main district medical center in the region was done to estimate the trends of HBV infection and qualitative interviews with the clinical staff of the CHB registry in the region were conducted to investigate the current status of HBV management. Out of 392,952 records, 371 (0.09%) HBV-positive were recorded and declining trends of the infection were noticed over the study period. Until late 2019, there was no linkage to care or follow-up for people with HBV infection. However, a CHB registry was established in late 2019 to manage HBV infections in the region, yet there are several barriers such as the lack of diagnostic infrastructure for liver function assessment and antiviral treatment. Despite the significant decline observed in the occurrence of HBV infection and introduction of important HBV management steps such as establishment of the CHB registry, there are still several barriers that could delay the elimination of the infection.

Aim: This study aims to utilize machine learning (ML) and logistic regression (LR) models to predict surgical outcomes among patients with traumatic brain injury (TBI) based on admission examination, assisting in making optimal surgical treatment decision for these patients. Method: We conducted a retrospective review of patients hospitalized in our department for moderate-to-severe TBI. Patients admitted between October 2011 and October 2022 were assigned to the training set, while patients admitted between November 2022 and May 2023 were designated as the external validation set. Five ML algorithms and LR model were employed to predict the postoperative Glasgow Outcome Scale (GOS) status at discharge using clinical and routine blood data collected upon admission. The Shapley (SHAP) plot was utilized for interpreting the models. Results: A total of 416 patients were included in this study, and they were divided into the training set (n = 396) and the external validation set (n = 47). The ML models, using both clinical and routine blood data, were able to predict postoperative GOS outcomes with area under the curve (AUC) values ranging from 0.860 to 0.900 during the internal cross-validation and from 0.801 to 0.890 during the external validation. In contrast, the LR model had the lowest AUC values during the internal and external validation (0.844 and 0.567, respectively). When blood data was not available, the ML models achieved AUCs of 0.849 to 0.870 during the internal cross-validation and 0.714 to 0.861 during the external validation. Similarly, the LR model had the lowest AUC values (0.821 and 0.638, respectively). Through repeated cross-validation analysis, we found that routine blood data had a significant association with higher mean AUC values in all ML and LR models. The SHAP plot was used to visualize the contributions of all predictors and highlighted the significance of blood data in the lightGBM model. Conclusion: The study concluded that ML models could provide rapid and accurate predictions for postoperative GOS outcomes at discharge following moderate-to-severe TBI. The study also highlighted the crucial role of routine blood tests in improving such predictions, and may contribute to the optimization of surgical treatment decision-making for patients with TBI.

Background: A serious complication after knee arthroscopy is venous thromboembolism (VTE), which includes both deep vein thrombosis (DVT) and pulmonary embolism (PE). However, asymptomatic VTE is frequently undetected. Purpose: To (1) report the incidence of VTE after knee arthroscopy using ultrasound examination and computed tomography pulmonary angiography (CTPA) and (2) discover the independent risk factors of VTE after knee arthroscopy and determine the corresponding cutoff values of these indicators. Study Design: Case-control study; Level of evidence, 3. Methods: Included were 222 patients (115 male) who underwent arthroscopic knee procedures between October 2022 and January 2023. Baseline characteristics, blood test results, and VTE assessments were collected. During the 2-week follow-up, routine lower extremity vascular ultrasound was applied for DVT measurement, with CTPA evaluation for suspected PE. Patients were allocated into VTE and no-VTE groups, and descriptive statistics were used to analyze baseline data. Logistic regression analysis was used to determine the correlation between binary variables and the presence of postoperative VTE. Multivariate logistic regression analysis was further performed to determine the independent risk factors of VTE. Results: Of the 222 patients, 37 (16.7%) had DVT and 1 (0.5%) had both DVT and PE. Compared to the no-VTE group, the VTE group was significantly older, with more female patients; higher body mass index (BMI) and postoperative D-dimer level; and higher rates of hypertension, hyperlipidemia, varicose veins of the lower extremity, and abnormal postoperative fibrin degradation product level (P ≤.043 for all). Notably, operative time >20 minutes was not significantly associated with postoperative VTE (P =.513). The independent risk factors for VTE included age >32 years (odds ratio [OR], 20.71 [95% CI, 4.40-97.47]; P <.001), BMI >23 kg/m2 (OR, 3.52 [95% CI, 1.11-11.14]; P =.032), hyperlipidemia (OR, 6.81 [95% CI, 1.86-24.88]; P =.004), and postoperative D-dimer level >0.63 mg/L (OR, 34.01 [95% CI, 7.36-157.07]; P <.001). Conclusion: The incidence of VTE after knee arthroscopy was 16.7% at the 2-week follow-up. Age >32 years, BMI >23 kg/m2, hyperlipidemia, and postoperative D-dimer >0.63 mg/L were independent risk factors of postoperative VTE within 2 weeks after knee arthroscopy. For patients with knee arthroscopy, the cutoff value of postoperative D-dimer for VTE was found to be 0.63 mg/L for timely intervention. [ABSTRACT FROM AUTHOR]

PURPOSE: In Southeastern Ontario, increased patient distance from the regional lung cancer diagnostic assessment program (LDAP) is associated with a lower likelihood of patient care via LDAP while receiving care via LDAP is associated with improved survival. We implemented an LDAP outreach clinic to provide specialist assessment for patients with suspected lung cancer at a regional community hospital and assessed the impact on timeliness and accessibility of care. MATERIALS AND METHODS: The Kingston Health Sciences Centre LDAP team engaged with community hospital partners to develop and launch the LDAP outreach clinic. We performed a retrospective chart review of LDAP patients (N = 1,070) before (August-November 2021; n = 234) and after implementation of the outreach clinic (November 2021-October 2022; n = 836). Descriptive data are reported as No. (%). Unpaired t tests and statistical process control charts assess for significance. A cost analysis of out-of-pocket patient costs related to travel and parking is presented in 2022 Canadian dollars (CAD). RESULTS: Compared with a 3-month matched time period before (August-October 2021) and after outreach clinic (August-October 2022), the mean time from referral to assessment and time from referral to diagnosis decreased from 20.3 to 14.4 days (P =.0019) and 40.0 to 28.9 days (P =.0007), respectively. Over 12 months, the total patient travel was reduced by 8,856 km, which combined with parking cost-savings, resulted in patient out-of-pocket savings of CAD $5,755.60 (CAD $47.60/patient). Accounting for physician travel, the total travel saved was 5,688 km, corresponding to reduced CO2 emissions by 1.9 tCO2. CONCLUSION: Implementation of a lung cancer outreach clinic led to improved timeliness of care, patient cost-savings, and reduced carbon footprint while serving patients in their community. LDAP outreach clinic led to faster lung cancer diagnosis, reduced patient costs, and lessened environmental impact. [ABSTRACT FROM AUTHOR]

Emergency medical services (EMSs) face critical situations that require patient risk classification based on analytical and vital signs. We aimed to establish clustering-derived phenotypes based on prehospital analytical and vital signs that allow risk stratification. This was a prospective, multicenter, EMS-delivered, ambulance-based cohort study considering six advanced life support units, 38 basic life support units, and four tertiary hospitals in Spain. Adults with unselected acute diseases managed by the EMS and evacuated with discharge priority to emergency departments were considered between January 1, 2020, and June 30, 2023. Prehospital point-of-care testing and on-scene vital signs were used for the unsupervised machine learning method (clustering) to determine the phenotypes. Then phenotypes were compared with the primary outcome (cumulative mortality (all-cause) at 2, 7, and 30 days). A total of 7909 patients were included. The median (IQR) age was 64 (51–80) years, 41% were women, and 26% were living in rural areas. Three clusters were identified: alpha 16.2% (1281 patients), beta 28.8% (2279), and gamma 55% (4349). The mortality rates for alpha, beta and gamma at 2 days were 18.6%, 4.1%, and 0.8%, respectively; at 7 days, were 24.7%, 6.2%, and 1.7%; and at 30 days, were 33%, 10.2%, and 3.2%, respectively. Based on standard vital signs and blood test biomarkers in the prehospital scenario, three clusters were identified: alpha (high-risk), beta and gamma (medium- and low-risk, respectively). This permits the EMS system to quickly identify patients who are potentially compromised and to proactively implement the necessary interventions. [ABSTRACT FROM AUTHOR]

Introduction: Osteoarthritis of the knee (OA knee) is a common geriatric disease that require total knee arthroplasty. Periprosthetic fracture is one of the common complications, which is strongly related to metabolic bone disease. Materials and methods: We conducted a prospective study on 291 outpatients with OA knee between November 2020 and April 2021. Baseline characteristics, dual-energy X-ray absorptiometry and blood test results were analysed using logistic regression analysis and expressed as odds ratio, 95% confidence intervals and P -values. Results: Overall metabolic bone diseases were found in 82.91% of patients. Vitamin D insufficiency (53.38%) was the most prevalent, followed by osteopenia (44.38%), impaired renal function (26.69%), and osteoporosis (17.45%). Risk factors of vitamin D insufficiency are age ≥71 years (OR 0.33, P = 0.003) and bilateral affected side (OR 1.99, P = 0.007). For osteopenia and osteoporosis, risk factors were age, body mass index, affected side, and chronic kidney disease (P < 0.05). Discussion: In the aspect of Vit D insufficiency, age>70 and bilateral OA knee were significantly related in many ways, such as reduction in cutaneous synthesis and daily exposure to sunlight and various diseases, including CKD and GI malabsorption. The risk factors of osteopenia and osteoporosis can be explained throughout several mechanisms. For instance, abnormality in hormone and cytokines metabolism will lead to the increase in adipocyte differentiation and fat accumulation. And that situation may lead to the decrease in osteoblast differentiation and increased osteoclast activity which could lead to negative impact on bone strength. Conclusions: Metabolic bone diseases were common in most patients with OA knee, and the insufficiency in amount of vitamin D(serum 25-hydroxyvitamin D), osteoporosis, and osteopenia conditions were mainly identified. These preventable conditions have risk factors that are mostly correctable These preventable conditions have risk factors that are mostly correctable, for example gain more outdoor activities, consume vitamin D supplement or start osteoporosis treatment program. Further analysis is necessary to establish solid evidence in the comparison of risk factors between the OA and non-OA groups. [ABSTRACT FROM AUTHOR]

Background. Takotsubo cardiomyopathy (TC) is a reversible left ventricular systolic dysfunction with apical ballooning. Left ventricular outflow tract (LVOT) obstruction may develop in these cases due to hyperdynamic state of the left ventricle. Limited data are available on the prevalence of LVOT gradient in TC and its association with patient outcomes and mortality. Methods. Data were collected retrospectively for patients diagnosed with TC in a single tertiary center, demographic information, blood analysis results, and imaging finding including ejection fraction, and LVOT gradient was obtained from medical records. Additionally, medical treatment and outcome during hospitalization were extracted. Follow‐up was conducted through cardiology clinic or phone contact. Result. A total of 59 patients diagnosed with TC were reviewed during hospitalization, and 40 patients were followed up after discharge by phone contact and cardiology clinic. Most patients were female (91.5%), and nonsignificant coronary artery disease was present in 16.9% of patients. Approximately two‐third of the patients had a reduced ejection fraction on admission, and only two patients (5.4%) continued to have reduced ejection fraction on echocardiography follow‐up within a period of 2–14 days. LVOT gradient was present in 17 patients (28.5%); patients with preserved ejection fraction had a higher probability of having an LVOT gradient. However, there was no association between LVOT gradient and shock or mortality. Four patients (6.7%) experienced 30‐day mortality, while all‐cause mortality was reported in eight patients (13.5%) over the follow‐up period (mean (±SD) 20.8 months ± 16.2). Conclusion. LVOT obstruction may occur in TC patients; it has no correlation with shock or mortality. However, determining whether there is a gradient is important for deciding on specific treatment approach.

Background: Allergen immunotherapy is the only treatment that can achieve remission for allergic diseases. Aims/Objectives: To investigate the three-year adherence to sublingual immunotherapy for Japanese cedar pollinosis and house dust mite allergy at a clinic in Japan and identify factors that influence adherence and severe adverse reactions. Material and Methods: In total, 174 patients aged 12 years or older who started sublingual immunotherapy for Japanese cedar pollinosis (n = 72), house dust mite allergy (n = 55), or both (n = 47) between May 2017 and June 2018. Patient age, sex, type of pharmacotherapy used, adverse reactions, blood test results, and duration of continuous treatment were investigated. Results: The three-year treatment continuation rate was 40.8%. Adverse reaction rates were 12.6% for cedar pollinosis and 40.2% for house dust mite allergy. Patients with dose reductions due to severe reactions had lower first-year continuation rates. In the MITICURE® group, patients with severe reactions had significantly higher serum total IgE levels. Severe reactions were more common in MITICURE® patients with seven or more positive antigen types. Conclusions and Significance: Severe adverse reactions reduced early adherence.

Background: Children's urinary system stones may develop from environmental, metabolic, anatomical, and other causes. Our objective is to determine the recurrence and prognosis, demographic, clinical, and etiological characteristics of children with urolithiasis. Methods: Medical records of patients were evaluated retrospectively. Patients' demographic data and medical history, serum/urine biochemical and metabolic analysis, blood gas analysis, stone analysis, imaging findings, and medical/surgical treatments were recorded. Results: The study included 364 patients (male 187). Median age at diagnosis was 2.83 (IQR 0.83–8.08) years. The most common complaints were urinary tract infection (23%) and urine discoloration (12%). Sixty-two percent had a family history of stone disease. At least one metabolic disorder was found in 120 (88%) of 137 patients having all metabolic analyses: hypercalciuria was found in 45%, hypocitraturia in 39%, and hyperoxaluria in 37%. Anatomical abnormalities were detected in 18% of patients. Of 58 stones analyzed, 65.5% were calcium and 20.6% were cystine stones. Stone recurrence rate was 15% (55/364). Older age (> 5 years), family history of stone disease, stone size (≥ 5 mm), and urinary system anatomical abnormalities were significantly associated with stone recurrence (p = 0.027, p = 0.031, p < 0.001, and p < 0.001, respectively). In adjusted logistic regression analysis, stone size ≥ 5 mm (OR 4.85, 95% CI 2.53–9.3), presence of urinary system anatomical abnormalities (OR 2.89, 95% CI 1.44–5.78), and family history of stone disease (OR 2.41, 95% CI 1.19–4.86) had increased recurrence rate. Conclusions: All children with urolithiasis should be evaluated for factors affecting stone recurrence. Children at higher risk of recurrence need to be followed carefully. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To phenotype the psychoneurologic (PN) symptom cluster in individuals with metastatic breast cancer and associate those phenotypes with individual characteristics and cancer genomic variables from circulating tumor DNA. SAMPLE & SETTING: This study included 201 individuals with metastatic breast cancer recruited in western Pennsylvania. METHODS & VARIABLES: A descriptive, crosssectional design was used. Symptom data were collected via the MD Anderson Symptom Inventory, and cancer genomic data were collected via ultralow-pass whole-genome sequencing of circulating tumor DNA from participant blood. RESULTS: Three distinct PN symptom phenotypes were described in a population with metastatic breast cancer: mild symptoms, moderate symptoms, and severe mood-related symptoms. Breast cancer TP53 deletion was significantly associated with membership in a moderate to severe symptoms phenotype (p = 0.013). IMPLICATIONS FOR NURSING: Specific cancer genomic changes associated with increased genomic instability may be predictive of PN symptoms. This finding may enable proactive treatment or reveal new therapeutic targets for symptom management. [ABSTRACT FROM AUTHOR]

Using pesticides in the An Giang province is widespread. However, studies on the health effect of organophosphate pesticide have not been updated within the past 12 years. This study aimed to assess exposure to organophosphate pesticides and their effects on sperm quality among farmers in the An Giang Province, Mekong Delta, Vietnam. During the winter – spring crop season of December 2021 to February 2022, a cross-sectional study was conducted on farmers aged 18 to 60 years-old based on seven communes' health checkup programs. The pesticide spray group included farmers who had sprayed pesticides in the previous week and had a history of working in agriculture for more than 2 years. The control group was defined as those who lived in the same community, had not worked in agriculture, and had never sprayed pesticides. Demographic characteristics and blood, urine, and semen samples were collected and analyzed. Data for 184 eligible participants were analyzed, including 116 farmers in the pesticide spray group and 68 non-farmers in the control group. Pesticide spray contributed to a decrease in the sperm quality index of 6.253 units (95% CI, 4.472–8.749). Increasing each pseudocholinesterase (PChE) unit (kIU/L) was associated with an increase of 1.181 units in the sperm quality index (95% CI, 0.757–0.947). Preventive methods for organophosphate pesticide exposure, such as administrative controls, engineering controls, substitution, and personal protective equipment should be applied to control health risks. In the An Giang setting, personal protective equipment is feasible, but most types of equipment are not used. The immediate priority is to determine the cause of personal protective equipment not being used and to find solutions to encourage people to use them. [ABSTRACT FROM AUTHOR]

Cyproterone acetate (CPA) and spironolactone (SPL) are different antiandrogens in gender-affirming hormone therapy (GAHT) for transgender women. Few studies have evaluated their efficacy and user satisfaction, especially among East Asians. This study aimed to evaluate these aspects in Chinese transgender women. Data were collected retrospectively from transgender women visiting the Peking University Third Hospital from 2012 to 2021. From 639 people identified as transgender women, 151 of them (80 using CPA and 71 using SPL, 16 to 40-year-old) under stable GAHT ≥6 months were enrolled. Total testosterone levels and visual analogue scale (VAS)-based satisfaction scores were evaluated. No difference was observed in age between the CPA and SPL groups (median [IQR], 22 [20–24] years and 23 [20–26] years, respectively). The duration of GAHT was longer in CPA group than in SPL group (18 [10–32] months vs. 12 [8–21] months, p = 0.009). Total testosterone levels were significantly lower with CPA treatment (25 mg/d) than with SPL treatment (100 mg/d) (median [IQR]: 0.7 [0.7–2.1] nmol/L vs. 13.0 [6.0–17.8] nmol/L, p < 0.001). The proportion of total testosterone levels reaching the recommended range was significantly higher in CPA group than in SPL group (75.0% vs. 11.3%, p < 0.001). VAS-based satisfaction scores for erection decreased and figure feminization were higher in CPA group than in SPL group, which remained unchanged after adjusting for age, treatment duration, estradiol dose, and comorbid mental disorders (p < 0.05). The prolactin levels were higher in CPA group than in SPL group (18.9 [11.8–28.1] ng/ml vs. 11.8 [7.9–18.4] ng/ml, p < 0.001). No severe safety events were reported in both groups. In Chinese transgender women, CPA was more effective than SPL in lowering testosterone levels. Additionally, VAS scores indicated greater satisfaction with erection decreased and figure feminization using CPA compared to SPL. [ABSTRACT FROM AUTHOR]

Hyperbilirubinemia is a physiological health problem of newborn infants, mostly occurring in the first week of life, which can delay development or cause disabilities or death. Massaging newborn infants early after delivery can promote bilirubin excretion and reduce hyperbilirubinemia. This quasi-experimental study aimed to determine the effect of infant massage performed by mothers on bilirubin levels and re-hospitalization for hyperbil- irubinemia. The study was conducted at an obstetrics and gynecology ward of a secondary hospital in Bangkok, Thailand. The participants were 30 paired full-term infants and mothers who met the inclusion criteria. The experimental group (n = 15) received body massage performed by their mother for 15 minutes twice a day for four consecutive days, while the control group (n = 15) received only usual care. The transcutaneous bilirubin levels were recorded at 6, 48, and 96 hours after birth. Data on re-hospitalization with hyperbilirubinemia were recorded on Day 7 after birth and analyzed using Fisher's exact test, independent t-test, and repeated measures ANOVA. The results revealed that the infants who received the massage had significantly lower mean bilirubin levels than those in the control group. However, there was no difference in the re-hospitalization with hyperbilirubinemia between the groups. In addition, the frequency of defecation on the first and fourth days in the experimental group was significantly greater than in the control group. The present study's result indicated that mothers' infant massage can help reduce bilirubin levels in full-term infants. The findings hold promise for nurses to integrate infant massage in training mothers at an early stage after birth for the prevention of hyperbilirubinemia in newborn infants. However, further testing with a larger sample size and randomized controlled trials are needed. [ABSTRACT FROM AUTHOR]

Introduction: The optimal strategy for differentiated thyroid cancer (DTC) patients treated with radioiodine (RAI) following thyroidectomy remains controversial. Multi-centre clinical studies are essential to identify strategies to improve patient outcomes while minimising treatment-induced toxicity. Materials and Methods: The INSPIRE clinical trial (ClinicalTrials.gov Identifier: NCT04391244) aims to investigate patient-specific dosimetry for DTC patients and to determine the range of absorbed doses delivered to target and nontarget tissues and their relationship with treatment outcome and toxicity. Results: We report here initial results of the first 30 patients enrolled onto the INSPIRE trial. A large range of absorbed doses are observed for both thyroid remnants and salivary glands, with median values of 4.8 Gy (Range 0.2 - 242 Gy) and 0.3 Gy (Range 0.1 to 1.7 Gy), respectively. Discussion: The preliminary study results are encouraging and could help to improve our understanding of absorbed doses to thyroid remnants and normal organs following RAI therapy. Such knowledge could potentially enable patientspecific treatment planning with improved clinical outcomes and quality-of-life of patients. [ABSTRACT FROM AUTHOR]

Industrial workers regularly perform physical labor under high heat stress, which may place them at risk for dehydration and acute kidney injury. Current guidelines recommend that workers should consume sports drinks to maintain euhydration during work shifts. However, the impact of fructose sweetened sports drinks on acute kidney injury risk is unknown. The purpose of this study was to investigate the effects of sports drink consumption on markers of acute kidney injury following simulated industrial work in the heat. Twenty males completed two matched 2 h simulated industrial work trial visits in a warm and humid environment (30 °C and 55% relative humidity). During and following the bout of simulated work, participants consumed either a commercially available sports drink or a noncaloric placebo. Urine and blood samples, collected pre-, post-, and 16 h post-work were assayed for markers of hydration (plasma/urine osmolality, and urine specific gravity) and acute kidney injury (KIM-1 and NGAL). There were no differences in physiological or perceptual responses to the bout of work (interaction p > 0.05 for all indices), and markers of hydration were similar between trials (interaction p > 0.05 for all indices). KIM-1 (Placebo: Δ Ln 1.18 ± 1.64; Sports drink: Δ Ln 1.49 ± 1.10 pg/mL; groupwide d = 0.89, p < 0.001) and NGAL (Placebo: Δ Ln 0.44 ± 1.11; Sports drink: Δ Ln 0.67 ± 1.22 pg/mL; groupwide d = 0.39, p = 0.03) were elevated pre- to post-work, but there were no differences between trials (interaction p > 0.05). These data provide no evidence that consumption of fructose sweetened sports drinks increases the risk of acute kidney injury during physical work in the heat. [ABSTRACT FROM AUTHOR]

Background: Detection of del(17p) in myeloma is generally performed by fluorescence in situ hybridization (FISH) on a slide with analysis of up to 200 nuclei. The small cell sample analyzed makes this a low precision test. We report the utility of an automated FISH method, called "immuno‐flowFISH", to detect plasma cells with adverse prognostic risk del(17p) in bone marrow and blood samples of patients with myeloma. Methods: Bone marrow (n = 31) and blood (n = 19) samples from 35 patients with myeloma were analyzed using immuno‐flowFISH. Plasma cells were identified by CD38/CD138‐immunophenotypic gating and assessed for the 17p locus and centromere of chromosome 17. Cells were acquired on an AMNIS ImageStreamX MkII imaging flow cytometer using INSPIRE software. Results: Chromosome 17 abnormalities were identified in CD38/CD138‐positive cells in bone marrow (6/31) and blood (4/19) samples when the percent plasma cell burden ranged from 0.03% to 100% of cells. Abnormalities could be identified in 14.5%–100% of plasma cells. Conclusions: The "immuno‐flowFISH" imaging flow cytometric method could detect del(17p) in plasma cells in both bone marrow and blood samples of myeloma patients. This method was also able to detect gains and losses of chromosome 17, which are also of prognostic significance. The lowest levels of 0.009% (bone marrow) and 0.001% (blood) for chromosome 17 abnormalities was below the detection limit of current FISH method. This method offers potential as a new means of identifying these prognostically important chromosomal defects, even when only rare cells are present and for serial disease monitoring.

Introduction: Ethylenediaminetetraacetic acid (EDTA)‐dependent platelet aggregation (PA) can cause medical errors. Currently, there is no reliable method for completely solving this problem. This study aims to solve this problem that has plagued clinical practice for many years by using oscillation method. Methods: Sixty‐one EDTA‐PA samples were collected, divided, and disaggregated using the oscillation method at various times and speeds. The samples were analyzed using routine blood tests and blood smears. Results: Platelet counts (PLT) were increased significantly after oscillation. PLT in the 3000 rpm for 0.5 min group was significantly higher than that in the 500 rpm for 0.5 min group (p < 0. 01). After 3000 rpm oscillation, the PLT gradually increased with time, while compared with the 10‐min group, the PLT in the 13‐min group showed no significant differences. The effective disaggregation rates in the EDTA‐PA samples using the oscillation method and sodium citrate anticoagulant were 96.72% and 65.57%, respectively. There were no significant changes in white blood cell (WBC) or red blood cell (RBC) counts or morphology after the use of the oscillation method. Conclusion: The oscillation method effectively depolymerized EDTA‐PA without adverse effects on WBC and RBC. The implementation of this technique promises to resolve the issue of EDTA‐PA.

Background: The MC‐80 (Mindray, Shenzhen, China), a newly available artificial intelligence (AI)‐based digital morphology analyzer, is the focus of this study. We aim to compare the leukocyte differential performance of the Mindray MC‐80 with that of the Sysmex DI‐60 and the gold standard, manual microscopy. Methods: A total of 100 abnormal peripheral blood (PB) smears were compared across the MC‐80, DI‐60, and manual microscopy. Sensitivity, specificity, predictive value, and efficiency were calculated according to the Clinical and Laboratory Standards Institute (CLSI) EP12‐A2 guidelines. Comparisons were made using Bland–Altman analysis and Passing‐Bablok regression analysis. Additionally, within‐run imprecision was evaluated using five samples, each with varying percentages of mature leukocytes and blasts, in accordance with CLSI EP05‐A3 guidelines. Results: The within‐run coefficient of variation (%CV) of the MC‐80 for most cell classes in the five samples was lower than that of the DI‐60. Sensitivities for the MC‐80 ranged from 98.2% for nucleated red blood cells (NRBC) to 28.6% for reactive lymphocytes. The DI‐60's sensitivities varied between 100% for basophils and reactive lymphocytes, and 11.1% for metamyelocytes. Both analyzers demonstrated high specificity, negative predictive value, and efficiency, with over 90% for most cell classes. However, the DI‐60 showed relatively lower specificity for lymphocytes (73.2%) and lower efficiency for blasts and lymphocytes (80.1% and 78.6%, respectively) compared with the MC‐80. Bland–Altman analysis indicated that the absolute mean differences (%) ranged from 0.01 to 4.57 in MC‐80 versus manual differential and 0.01 to 3.39 in DI‐60 versus manual differential. After verification by technicians, both analyzers exhibited a very high correlation (r = 0.90–1.00) with the manual differential results in neutrophils, lymphocytes, and blasts. Conclusions: The Mindray MC‐80 demonstrated good performance for leukocyte differential in PB smears, notably exhibiting higher sensitivity for blasts identification than the DI‐60.

It has been assumed that exercise intensity variation throughout a cycling time trial (TT) occurs in alignment of various metabolic changes to prevent premature task failure. However, this assumption is based on target metabolite responses, which limits our understanding of the complex interconnection of metabolic responses during exercise. The current study characterized the metabolomic profile, an untargeted metabolic analysis, after specific phases of a cycling 4‐km TT. Eleven male cyclists performed three separated TTs in a crossover counterbalanced design, which were interrupted at the end of the fast‐start (FS, 600 ± 205 m), even‐pace (EP, 3600 ± 190 m), or end‐spurt (ES, 4000 m) phases. Blood samples were taken before any exercise and 5 min after exercise cessation, and the metabolomic profile characterization was performed using Nuclear Magnetic Resonance metabolomics. Power output (PO) was also continually recorded. There were higher PO values during the FS and ES compared to the EP (all p < 0.05), which were accompanied by distinct metabolomic profiles. FS showed high metabolite expression in TCA cycle and its related pathways (e.g., glutamate, citric acid, and valine metabolism); whereas, the EP elicited changes associated with antioxidant effects and oxygen delivery adjustment. Finally, ES was related to pathways involved in NAD turnover and serotonin metabolism. These findings suggest that the specific phases of a cycling TT are accompanied by distinct metabolomic profiles, providing novel insights regarding the relevance of specific metabolic pathways on the process of exercise intensity regulation. Highlights: Untargeted metabolomic profile analysis may reveal unexplored bioenergetic pathways activated throughout a self‐paced cycling time trial.Exercise intensity variations throughout a cycling time trial are accompanied by different blood serum metabolomic profiles.The current new insights may encourage future investigation on the underpinning mechanisms of specific metabolomic profiles according to each time trial phase.

This pilot study aimed to assess the impact of substituting a traditional lunch for a vegetarian legume‐based meal on blood and anthropometric parameters in a group of omnivorous adults. A one‐group comparison, quasi‐experimental dietary intervention was designed. A vegetarian legume‐based meal was offered for 8 consecutive weeks (weekdays) to non‐vegetarian individuals (n = 26), (28 years [P25 = 20.0, P75 = 35.5]; 21.9 kg/m2 [P25 = 21.3, P75 = 24.8]). Sociodemographic data, health status and lifestyle‐related information were recorded. Three‐day food records were used to collect food intake at baseline and at the end of the intervention. Anthropometric parameters were recorded and fasting blood analyses were performed following standard procedures. Wilcoxon signed‐rank test was used for statistical comparisons. A p‐value <0.05 was considered statistically significant. Participants showed a median intake of 79.8 g of cooked legumes per meal, meaning 13 (50.0%) subjects met the Portuguese daily legume intake recommendations during the intervention days. There were no statistically significant differences in anthropometric parameters. Transferrin concentration increased after 8 weeks (+12.5 mg/dL; p = 0.001). Total cholesterol concentration reduced after 8 weeks (−6 mg/dL; p = 0.041), as well as low‐density lipoprotein (LDL) cholesterol (−7 mg/dL; p = 0.003). Triglycerides (+9 mg/dL; p = 0.046), fasting glucose (+2 mg/dL; p = 0.037) and HbA1c (+0.1 mg/dL; p = 0.010) concentration increased after the 2‐month legume‐based trial. Results suggest a cholesterol‐lowering potential of legume‐rich diets. However, unfavourable results regarding the impact on glucose metabolism‐related biomarkers and triglyceride levels were observed. The study's limitations in design and sample size emphasise the importance of conducting further research with larger cohorts to attain more conclusive findings. [ABSTRACT FROM AUTHOR]

Background and Design: Hematological parameters have been used as laboratory markers to evaluate the systemic inflammation in several rheumatic disease. The aim of this study is to determine the difference of hematological parameters between the patients who have been just fulfilled the Behçet's disease (BD) criteria and patients with recurrent aphthous stomatitis (RAS). Materials and Methods: Twenty patients with newly diagnosed BD and 47 patients with RAS whose oral ulcerations appeared at least three times a year were enrolled in this cross-sectional study. Demographic and clinical characteristics of patients, complete blood count, C-reactive protein (CRP) and erythrocyte sedimentation rate were recorded. Results: Patients' characteristics including gender, age, duration, and frequency of oral aphthous ulcerations in both study groups were comparable (p>0.05). CRP was significantly higher in newly diagnosed BD group when compared to the RAS group (p=0.001). CRP value higher than 2.7 g/dL, mean platelet volume (MPV) value higher than 7.58 fL and lymphocyte count higher than 2.85 103/μL were found to be the markers for distinguishing patients with BD from patients with RAS [odds ratio (OR): 12.76 (95% confidence interval (CI): 2.86-56.88), OR: 5.61 (95% CI: 1.11-28.42), OR: 15.24 (95% CI: 1.77-131.31), respectively]. Conclusion: The elevated CRP, MPV and lymphocyte count were associated with patients with newly diagnosed BD rather than patients with RAS. Further large prospective studies with the healthy control group are needed to confirm these findings. [ABSTRACT FROM AUTHOR]
