A Large-Scale Serological Survey in Pets From October 2020 Through June 2021 in France Shows Significantly Higher Exposure to SARS-CoV-2 in Cats Compared to Dogs.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has the potential to infect various animals, including domestic pets like dogs and cats. Many studies have documented infection in companion animals by molecular and serological methods. However, only a few have compared seroprevalence in cats and dogs from the general population, and these studies were limited by small sample sizes and collections over short periods. Our aim was to obtain a more accurate evaluation of seroprevalence in companion animals in France and to determine whether cats and dogs differ in their exposure to SARS-CoV-2. We conducted an extensive serological survey of SARS-CoV-2, collecting blood samples from 2036 cats and 3577 dogs during routine veterinary medical examinations across different regions of metropolitan France from October 2020 to June 2021. This period encompassed the peaks and onset of two waves, as well as the emergence of the first variants. A microsphere immunoassay targeting the receptor-binding domain and trimeric spike protein was used to detect anti-SARS-CoV-2 antibodies. A subset of 308 seropositive samples was tested for the presence of neutralising antibodies. We determined an overall seroprevalence of anti-SARS-CoV-2 antibodies of 7.1% (95% confidence interval [CI]: 6.4%-7.8%) among the sampled pets. Cats exhibited a significantly higher seroprevalence (9.3%; 95% CI: 8.1%-10.1%) compared to dogs (5.9%; 95% CI: 5.2%-6.8%). Among the subset of seropositive samples, 81 (26.3%; 95% CI: 21.5%-31.6%) displayed neutralizing antibodies. Furthermore, seroprevalence in both species was lower in older animals and was not associated with sex. Finally, unlike cats, seroprevalence in dogs was found to be correlated with the date of sampling. The large sample size enhances the reliability and statistical robustness of our estimates regarding pet exposure to SARS-CoV-2. This study on SARS-CoV-2 reaffirms the crucial importance of adopting a One Health approach incorporating domestic animals when managing an epidemic caused by a zoonotic virus.

Wavelet-Detected Changes in Nocturnal Brain Electrical Activity in Patients with Non-Motor Disorders Indicative of Parkinson's Disease.

Background/Objectives-Parkinson's disease (PD) is the second most common neurodegenerative disorder caused by the destruction of neurons in the substantia nigra of the brain. Clinical diagnosis of this disease, based on monitoring motor symptoms, often leads to a delayed start of PD therapy and control, where over 60% of dopaminergic nerve cells are damaged in the brain substantia nigra. The search for simple and stable characteristics of EEG recordings is a promising direction in the development of methods for diagnosing PD and methods for diagnosing the preclinical stage of PD development. Methods-42 subjects participated in work, of which 4 female/10 male patients were included in the group of patients with non-motor disorders, belonging to the risk group for developing PD (median age: 62 years, height: 164 cm, weight: 70 kg, pulse: 70, BPsys and BPdia: 143 and 80)/(median age: 68 years, height: 170 cm, weight: 73.9 kg, pulse: 75, BPsys and BPdia: 143 and 82). The first control group of healthy participants included 6 women (median age: 33 years, height: 161 cm, weight: 66 kg, pulse: 80, BPsys and BPdia: 110 and 80)/8 men (median age: 36.3 years, height: 175 cm, weight: 69 kg, pulse: 78, BPsys and BPdia: 120 and 85). The second control group of healthy participants included 8 women (median age: 74 years, height: 164 cm, weight: 70 kg, pulse: 70, BPsys and BPdia: 145 and 82)/6 men (median age: 51 years, height: 172 cm, weight: 72.5 kg, pulse: 74, BPsys and BPdia: 142 and 80). Wavelet oscillatory pattern estimation is performed on patients' nocturnal sleep recordings without separating them into sleep stages. Results-Amplitude characteristics of oscillatory activity in patients without motor disorders and the prodromal PD stage are significantly reduced both in terms of changes in the number of patterns and in terms of their duration. This pattern is especially pronounced for high-frequency activity, in frequency ranges close to 40 Hz. Conclusions-The success of the analysis of the electrical activity of the brain, performed over the entire duration of the night recording, makes it promising to further use during daytime monitoring the concept of oscillatory wavelet patterns in patients with non-motor disorders, belonging to the risk group for developing PD. The daytime monitoring system can become the basis for developing screening tests to detect neurodegenerative diseases as part of routine medical examinations.

Thinking style and nature of stress experience in patients with coronary artery disease

Aim. To analyze the cognitive status (thinking style and nature of stress experience) in patients with coronary artery disease (CAD) who underwent myocardial revascularization.Material and methods. The study involved 150 patients with the average age of 54 years. The study sample included three following groups of respondents: patients with CAD who underwent myocardial revascularization 1,5 months before the study (n=50); patients with cerebral ischemia (n=50); conditionally healthy respondents who underwent routine medical examination (n=50). The following were used: the Cognitive Mistakes Questionnaire by A. Freeman, R. DeWolf (in the Russian adaptation by A.E. Bobrov, E.V. Fayzrakhmanova); the Questionnaire of Styles of Explanation of Successes and Failures by T.O. Gordeeva, O.A. Sychev, E.N. Osin, V.A. Titova Gransham; the Brief Resilience Scale by B. Smith, et al. (in the Russian adaptation by V.I. Markova, L.A. Alexandrova, A.A. Zolotareva); the State-Trait Anxiety Inventory by C. D. Spielberger (in the Russian adaptation by Yu.L. Khanin). To assess the significance of differences in cognitive status and the nature of stress experience between the above-mentioned groups, Student's t-test (t) was used. Statistical analysis was performed using SPSS Statistics ver. 27.0.1.Results. Patients with CAD who underwent myocardial revascularization differ from conditionally healthy patients who underwent routine medical examination, in higher expression of following cognitive status indicators: "catastrophizing" (t=-6,718 at p<0,01), "stability of failures" (t=-3,092 at p<0,01), high expression of personal anxiety (t=-5,238 at p<0,01) and low expression of resilience (t=3,163 at p<0,01). In addition, CAD patients differ from patients with cerebral ischemia in higher expression of the cognitive status parameter "exaggeration of danger" (t=-6,292 at p<0,01).Conclusion. In patients with CAD, the indicators of cognitive status and ability to recover after revascularization may indicate chronic traumatization caused by disease and surgery as the trigger event. The data obtained may be important for the development of prevention and rehabilitation programs.

Association between total functional tooth unit score and hemoglobin A1c levels in Japanese community-dwelling individuals: the Nagasaki Islands study.

It is widely recognized that periodontal disease is associated with diabetes mellitus. Periodontal disease is accompanied by inflammation of the periodontal tissue, impaired masticatory function, and the presence of periodontopathic bacteria, all of which may affect glycemic control. However, the exact relationship between these factors and glycemic control has not yet been established. In this study, we aimed to investigate the relationship between periodontal disease-related factors and glycemic control in Japanese community-dwelling individuals. We conducted a cross-sectional study involving 671 participants aged 29-92 (65.3 ± 12.1) years, using data from the Nagasaki Islands Study. Participants underwent routine medical examinations, including body mass index (BMI) and hemoglobin A1c (HbA1c) levels. Information on the participants' demographics (age and sex) and whether they were on diabetes medications, had an exercise habit, consumed alcohol, engaged in late-night eating, had regular dental checkups, and smoked was obtained using a self-administered questionnaire. Dental examinations were performed to examine dentition status, probing pocket depth, clinical attachment level (CAL), and bleeding on probing. Functional tooth units (FTUs), defined as pairs of occluding posterior teeth, were used as an indicator of occlusal support area. Saliva samples were collected and levels of two species of periodontopathic bacteria (Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans) were determined using real-time polymerase chain reaction. We analyzed the association between HbA1c levels and variables related to periodontal status, masticatory function, and salivary levels of periodontopathic bacteria. Bivariate analysis showed that HbA1c levels were significantly associated with age, sex, exercise habit, BMI, diabetes medications, CAL, salivary P. gingivalis level, number of teeth, and three FTU subcategories. In the multiple regression analysis, age, BMI, diabetes medications, and total FTU score (i.e., including natural teeth, implant-supported artificial teeth, fixed prostheses, and removable dentures) remained associated with HbA1c levels (B = 0.23, 0.14, 0.52, and - 0.12; p < 0.001, p < 0.001, p < 0.001, and p = 0.008, respectively). In this community-based cross-sectional study, total FTU was significantly associated with HbA1c levels, independent of other risk factors. This suggests that reconstructed occlusal support areas, including dentures, are associated with glycemic control in the older population.

Development and validation of an image-based questionnaire ARTROVIS to identify risk factors for the articular syndrome and related conditions

Background: The importance of timely diagnosis of rheumatic diseases is beyond any doubt. However, in the real practice the time from manifestation of the first symptoms to the assessment by a rheumatologist and treatment administration often exceeds the window of opportunity for disease control. At the moment, there has been no Russian-language questionnaire that would allow a primary care physician to suspect a rheumatic disease manifesting with an articular syndrome. Aim: To develop, validate and test a questionnaire to identify risk factors for joint disorders and related conditions. Methods: From November 2022 to April 2024, we performed the study on the image-based questionnaire on identification of the risk factors for joint syndromes and associated conditions (ARTROVIS), which we have developed for early detection of both joint syndromes, as well as comorbid conditions associated with elevated serum uric acid levels (hyperuricemia). The initial test version of the questionnaire was tested in a focus group of respondents (n = 20) who came for regular medical examination. Based on the results of this face validity assessment, we corrected the wording of 10 questionnaire items. At the second study step, we assessed the primary validity and reliability of the questionnaire in a group of 41 rheumatology patients. The third study step involved 828 respondents (408 men and 420 women, median age 19 [18,0; 20,0] years; 21% with joint syndromes), who came for routine medical examination. The reliability of the questionnaire, its face and discriminant validity, as well as sensitivity and specificity (the ROC analysis) were assessed from 827 questionnaires included in the final processing (one was excluded due to questionnaire completion defects). Results: The self-report questionnaire for patients (ARTROVIS) has 24 items aimed at collecting social and demographic data, identifying risk factors for non-communicable diseases, assessing genetic aspects, identifying complaints from various organ systems, providing information on medical treatments taken by the patient (non-steroid anti-inflammatory agents, diuretics, antihypertensives, glucocorticosteroids, chemotherapy and radiation therapy), as well as an additional question for women on current pregnancy pathology. The questionnaire contains visual aids (colored photos) that facilitate the detection of clinical signs of autoimmune (psoriatic arthritis, Reynolds’s syndrome) and inflammatory rheumatic disease (gout), as well as the differential diagnosis of the joint syndrome. The assessment of face validity of the questionnaire showed the total number of missed answers of 3.42%; 62.85% of the respondents gave their full answers to all items. Good discriminant validity was demonstrated. The ROC analysis showed high correlation between the questionnaire score and the presence of a joint syndrome: the area under the curve was 0.884. The Cronbach’s alfa was 0.798, which is sufficient for a medical questionnaire. Conclusion: We have performed the approbation and standardization of the questionnaire to identify risk factors for the joint syndrome and related comorbidities by assessing its validity and reliability. The ARTROVIS as a self-report questionnaire can be used in primary care as a tool enabling general practitioners and internists to decide on further patient routing to corresponding specialists.

Malignant Non-Odontogenic Tumors of the Oral Cavity – Single Institutional Retrospective Study of Three Decades

Abstract Malignant non-odontogenic tumors of the oral cavity remain understudied in India, despite their global prevalence. This retrospective analysis examined cases from a single institution in Maharashtra between 1990 and 2021, focusing on patient demographics, clinical presentations, and histopathological features. Oral squamous cell carcinoma (OSCC) emerged as the predominant malignancy, with epithelial malignancies accounting for 98.6% of cases. A slight male predominance was observed. Buccal mucosa was the most frequent site of occurrence, with tobacco chewing identified as the primary risk factor. This study underscores the need for increased attention to oral malignancies in routine medical examinations and calls for more comprehensive statistical analysis to inform clinical practice and public health strategies.

Utilizing radiomics techniques to isolate a single vertebral body from chest CT for opportunistic osteoporosis screening

PurposeOpportunistic osteoporosis screening, conducted during routine medical examinations such as chest computed tomography (CT), presents a potential solution for early detection. This study aims to investigate the feasibility of utilizing radiomics technology based on chest CT images to screen for opportunistic osteoporosis.MethodsThis Study is a Multicenter Retrospective Investigation. Relevant clinical data, including demographics and DXA results, would be collected for each participant. The radiomics analysis in this study focuses on the extraction of features from the 11th or 12th thoracic vertebral bodies from chest CT images. SVM machine learning models would be trained using these radiomic features, with DXA results as the ground truth for osteoporosis classification.ResultsIn the training group, Clinical models had an accuracy of 0.684 and an AUC of 0.744, Radiomics models had an accuracy of 0.828 and an AUC of 0.896, Nomogram models had an accuracy of 0.839 and an AUC of 0.901. In the internal validation group, Clinical models had an accuracy of 0.769 and an AUC of 0.829, Radiomics models had an accuracy of 0.832 and an AUC of 0.892, Nomogram models had an accuracy of 0.839 and an AUC of 0.918. In the external validation group, Clinical models had an accuracy of 0.715 and an AUC of 0.741, Radiomics models had an accuracy of 0.777 and an AUC of 0.796, Nomogram models had an accuracy of 0.785 and an AUC of 0.807. In all three datasets, the Nomogram model exhibited a statistically significant difference in screening effectiveness compared to the clinical models.ConclusionOur research demonstrates that by leveraging radiomics features extracted from a single thoracic spine using chest CT, and incorporating these features with patient basic information, opportunistic screening for osteoporosis can be achieved.

Quantification measurement of hemoglobin with large dynamic range and low detection limit via an optical fiber optofluidic laser with enzyme-catalyzed reaction

Quantitative measurement of hemoglobin (Hb) levels is an essential part of routine medical examinations, disease diagnosis and health status monitoring. In this study, we introduced optical fiber optofluidic laser (FOFL) technology combined with catalytic oxidation reaction to design a laser sensor for sensitive Hb detection. For the H2O2-rhodamine B (RhB) oxidation system, radially emitting FOFL was achieved with a thin-walled hollow optical fiber (HOF) as an optical microcavity and amplified the concentration change of RhB during oxidation by H2O2. Hb was employed as peroxide-mimicking enzyme to catalyze the oxidation system, which sped up the reaction, resulting in an earlier laser extinction time. With the laser extinction time as sensing signal, the Hb sensor achieved a dynamic range of five orders of magnitude and a limit of detection (LOD) of 46.0 pM at an assay time of 40 min. The developed method provides ideas for the exploitation of FOFL biosensing based on catalytic oxidation reactions.

Seasonal variations in haematological and biochemical parameters of healthy Gambian adults: Retrospective study 2018-2022.

The objectives of this study were to determine the presence and effect of seasonal variations and provide insights into trend from 2018 to 2022 in a comprehensive set of routine haematological indices and biochemical measurements in Gambian adults with no known underlying health condition. We retrieved five years of data from an electronic database and analysed 493 full blood counts and 643 biochemical data from different individuals. In this study, we focused on data from individuals with no known underlying health condition who visited the clinical diagnostic laboratory for routine medical examinations or assessments.Our study found a positive association between seasonality (wet season as the reference) and Hb (HB: 0.014(0.015), P<0.05), White blood cells (WBC) (WBC: 0.243(0.163), p = 0.0014), and neutrophils (neutrophils: 0.271(0.131), P<0.05) with exception to red blood cells (RBC) (RBC: - 0.184(0.061), P< 0.003) that showed negative association. Despite the association, the seasonal effects on our derived reference intervals for haematological indices and biochemical measurements from wet season to dry season were not statistically significant (P>0.05). In addition, we observed in our heatmap result that some laboratory parameters, including HB, RBC, haematocrit (HCT), urea, liver enzymes, and potassium, showed seasonal variation patterns throughout the year, with median levels being normal to slightly low during the dry season and normal to high during the wet season. We also found no significant difference (P>0.05) among the median values for all parameters from 2018 to 2022. Additionally, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) parameters showed a consistent declining trend from 2018 to 2022. Our study found no seasonal effects on the derived reference intervals of haematological indices and biochemical measurements. However, we observed changes in patterns for certain parameters particularly HB, RBC, liver enzymes, and potassium based on seasonality.

The predictive capability of several anthropometric indices for identifying the risk of metabolic syndrome and its components among industrial workers

Metabolic syndrome (MetS) is closely associated with adverse cardiometabolic outcomes. The objective of this study was to identify practical methods that could enable the effective identification of MetS based on anthropometric indices. The basis of our study involved retrospective database obtained from routine medical prophylactic examinations. This was a cross-sectional study on the health status of male workers employed in hazardous working conditions at industrial enterprises in the Ural region conducted in 2019. A total of 347 male workers employed under hazardous working conditions were investigated. The presence of MetS was established by a healthcare professional in accordance with the guidelines of the International Diabetes Federation (IDF). Simple linear regression was used to evaluate the associations between anthropometric indices and MetS incidence. Logistic regression was used to determine the odds ratios of MetS in relation to increases in anthropometric indices. ROC curves were calculated to compare the ability of each anthropometric index to predict MetS and to determine the diagnostic thresholds of the indicators considered. According to the IDF criteria, 36.3% of the workers had MetS. A direct relationship was found between the individual components of MetS and the anthropometric indices studied. The highest OR was shown by the Body Roundness Index (BRI) of 2.235 (95% CI 1.796–2.781). For different age quartiles, the optimal cut-off values for predicting MetS were as follows: BRI, 4.1–4.4 r.u.; body shape index (ABSI), 0.080–0.083 m11/6 kg−2/3; and lipid accumulation product (LAP), 49.7–70.5 cm mmol/l. The most significant associations with MetS were observed where the values were greater than these cut-off points (Se = 97.4%). The results of this study demonstrated the rapid use of new anthropometric indicators, which have shown good predictive ability and are quite easy to use.

Cardiac murmurs in children.

Approximately 50% of children experience a cardiac murmur at some point in their lives; <1% of these murmurs are attributed to congenital heart disease (CHD). Cardiac murmur might be the first clinical sign of a significant CHD in children. Despite careful routine medical examinations at birth, approximately 50% of CHD cases could remain unrecognised. Cardiovascular symptoms and signs could be specific or non-specific in neonates and children with heart murmurs. Knowledge about red flags in history and physical examinations, and syndromic associations of common CHDs are important. Auscultatory skills to identify systolic, diastolic and continuous murmurs and heart sounds are essential. Differential diagnosis should be formulated based on the location of maximum intensity of murmurs. Younger infants and children with pathological murmurs and red-flag signs should be promptly referred to local paediatric cardiology services for further investigations. Significant skill and knowledge are required for the identification of critical murmurs and associated cardiovascular problems. This review provides a simplified comprehensive update on cardiac murmurs and associated conditions in neonates and children.

Nailfold Capillaroscopy: A Comprehensive Review on Its Usefulness in Both Clinical Diagnosis and Improving Unhealthy Dietary Lifestyles.

Since the 1970s, the utility of nailfold capillaroscopy (NFC) in diagnosing rheumatological disorders such as systemic sclerosis has been well established. Further studies have also shown that NFC can detect non-rheumatic diseases such as diabetes, glaucoma, dermatitis, and Alzheimer disease. In the past decade, nailfold capillary morphological changes have also been reported as symptoms of unhealthy lifestyle habits such as poor diet, smoking, sleep deprivation, and even psychological stress, all of which contribute to slow blood flow. Therefore, studying the relationships between the morphology of nailfold capillaries and lifestyle habits has a high potential to indicate unhealthy states or even pre-disease conditions. Simple, inexpensive, and non-invasive methods such as NFC are important and useful for routine medical examinations. The present study began with a systematic literature search of the PubMed database followed by a summary of studies reporting the assessment of morphological changes detected by NFC, and a comprehensive review of NFC's utility in clinical diagnosis and improving unhealthy dietary lifestyles. It culminates in a summary of dietary and lifestyle health promotion strategy, assessed based on NFC and other related measurements that indicate healthy microvascular blood flow and endothelial function.

Oxidative stress induced by the human microbiota yeast component as a micromycetes pathogenicity factor

The introduction of MALDI-ToF mass spectrometry into routine microbiological diagnostics has led to a widely extended list of identified microorganisms. This phenomenon also affected mycological studies. Rare basidiomycetes and ascomycetes began to be detected in various types of pathological material. It is often difficult to assess a role of isolated micromycetes in the pathogenesis of a certain disease. In addition to generally admitted pathogenicity factors, such as aggression enzymes, adhesive activity, and toxin formation, induction or inhibition of reactive oxygen species can play a prominent role in pathogenesis of infectious diseases. In our study, we evaluated the total prooxidant and total antioxidant activity of cultivated ascomycete and basidiomycete yeasts from the human intestinal mycobiome. The strains of micromycetes assessed here were obtained from a fecal culture study from patients with gastrointestinal tract pathology and healthy people undergoing a routine medical examination. Identification was carried out analyzing morphological, cultural, biochemical properties and confirmed by mass spectrometry. The total prooxidant and antioxidant activity was assessed by the induced or inhibited malondialdehyde formation during Tween-80 oxidation. It was found that the level of total prooxidant activity in Rhodotorula mucilaginosa, Geotrichum candidum, Candida albicans, Pichia kudriavzevii significantly exceeds the level of total antioxidant activity, and the Pichia kudriavzevii prooxidase activity was more than twice as high as in other studied micromycetes. The revealed ability of some fungi to induce oxidase stress can be considered as one of significant pathogenicity factors of microorganisms that cause pathomorphological changes in human intestinal tissues.

Postoperative delayed massive bleeding in gastric cancer: a case report

BackgroundPostoperative delayed bleeding of gastric cancer is a complication of radical gastrectomy with low incidence rate and high mortality.Case presentationThis case report presents the case of a 63-year-old female patient of Mongolian ethnicity who was diagnosed with gastric malignancy during a routine medical examination and underwent Billroth's I gastric resection in our department. However, on the 24th day after the surgery, she was readmitted due to sudden onset of hematemesis. Gastroscopy, abdominal CT, and digital subtraction angiography revealed postoperative anastomotic fistula, rupture of the duodenal artery, and bleeding from the abdominal aorta. The patient underwent three surgical interventions and two arterial embolizations. The patient’s condition stabilized, and she was discharged successfully.ConclusionCurrently, there are no specific guidelines for the diagnosis and treatment of pseudoaneurysms in the abdominal cavity resulting from gastric cancer surgery. Early digital subtraction angiography examination should be performed to assist in formulating treatment plans. Early diagnosis and treatment contribute to an improved overall success rate of rescue interventions.

Awareness of parasitic zoonotic diseases among pet owners in Cairo, Egypt

Egyptians are becoming more interested in owning and raising pets; however, most of them lack essential awareness about the risk of zoonotic parasites that could be transmitted. The objective of the present investigation was to evaluate the degree of awareness Egyptian pet owners possess concerning zoonotic parasitic diseases, the risk of transmission, and preventative measures. A cross-sectional study was conducted using an e-survey. Among 246 pet owners, 64.2% (158) were females, and 67.9% (167) belonged to the 20–30 age group. The majority, 78.9% (194), were raising cats. Only 13.8% (34) visited the veterinarian regularly, with significantly higher results among dog owners (p < 0.05). Only 31.3% (77) participants were regularly deworming their pets, and 19.9% (49) were giving their pets prophylaxis against ectoparasites, with significantly higher results among those who visited the veterinarian regularly (p < 0.0001) and among dog owners (p < 0.05). Only 54.1% (133) had heard about the term “zoonoses” before, and about 8.9% (22) of participants showed a history of zoonotic parasitic diseases, with significantly higher results among those who allowed their animals to play with other animals of neighbors and friends (p < 0.05). The obtained results concluded that the surveyed group had a relatively good degree of knowledge regarding pets as a source of zoonotic illness; raising pet owners' awareness regarding the importance of routine medical examinations and minimizing the contact of pets with other stray animals is essential.

Knowledge and Attitude of Patients Attending Primary Health Care (PHC) or Family Medicine Clinics About Periodic Health Assessment.

Background This study assesses the awareness and perceptions of periodic health assessments (PHA) among patients at primary health care (PHC) and family medicine clinics. Despite PHC's importance in preventive health, previous research indicates a significant gap in the public's knowledge and routine practice of PHA, potentially affected by various demographic factors. Materials & methods A cross-sectional approach was employed in Riyadh, Saudi Arabia, with data gathered via self-administered questionnaires from 382 participants. The survey focused on socio-demographic information, knowledge about PHA, and attitudes towards it. Statistical analysis explored the influence of demographic and clinical factors on individuals' knowledge and attitudes. Results Findings showed that 300 (78.5%) participants had engaged in routine medical examinations, displaying substantial knowledge of PHA. Nevertheless, issues like healthcare accessibility and provider availability were identified as the major barriers, affecting 125 (32.7%) and 84 (22%) participants, respectively. The overall attitude towards PHA was positive, especially among individuals with chronic conditions, emphasizing its perceived benefits in health management. Conclusion The research underscores a generally positive attitude and fair knowledge level regarding PHA among the studied population, alongside significant barriers to participation. Targeted interventions that address these barriers and capitalize on the positive attitudes may enhance PHA uptake, promoting better health outcomes. This study contributes to the understanding of public engagement with PHA, offering insights for improving health promotion and disease prevention strategies.

Visualizing a Cold Stress-Specific Pulse Wave in Traditional Pulse Diagnosis ('Tight Pulse') Correlated with Vascular Changes in the Radial Artery Induced by a Cold Pressor Trial.

Radial pulse diagnosis is the most common method to examine the human health state in Traditional East Asian Medicine (TEAM). A cold stress-related suboptimal health state (subhealth) is often undetectable during routine medical examinations, however, it can be detected through the palpation of specific pulse waves, particularly a 'tight pulse', in TEAM. Therefore, this study examined a correlation between 'tight pulse' and vascular changes in the radial artery (RA) induced by a cold pressor trial (CPT). Twenty healthy subjects underwent sequentially control trial and CPT with room-temperature and ice-cold water, respectively, on the right forearm. The radial pulse and vascular changes were then examined on the left arm. The radial pulse scores for frequencies of 'tight pulse' with strong arterial tension increased after the CPT compared with the control trial. The pulse scores were reversely correlated with the RA thickness and volumes in ultrasonography, but not with changes in the systolic/diastolic blood pressure. The RA thickness-based vascular surface and three-dimensional images visualized a 'tight pulse' showing the vasoconstriction and bumpy-/rope-shaped vascular changes in the radial pulse diagnostic region after the CPT. These findings provide valuable insights into the potential integration of clinical radial pulse diagnosis with ultrasonography for cold-related subhealth.

Gender-specific association between blood cell parameters and hyperuricemia in high-altitude areas.

Hyperuricemia is a common metabolic disorder linked to various health conditions. Its prevalence varies among populations and genders, and high-altitude environments may contribute to its development. Understanding the connection between blood cell parameters and hyperuricemia in high-altitude areas can shed light on the underlying mechanisms. This study aimed to investigate the relationship between blood cell parameters and hyperuricemia in high-altitude areas, with a particular focus on gender differences. We consecutively enrolled all eligible Tibetan participants aged 18-60 who were undergoing routine medical examinations at the People's Hospital of Chaya County between January and December 2022. During this period, demographic and laboratory data were collected to investigate the risk factors associated with hyperuricemia. Among the participants, 46.09% were diagnosed with hyperuricemia. In the male cohort, significant correlations were found between serum uric acid (SUA) levels and red blood cell (RBC) count, creatinine (Cr). Urea, alanine transaminase (ALT), and albumin (ALB). Notably, RBC exhibited the strongest association. Conversely, in the female cohort, elevated SUA levels were associated with factors such as white blood cell (WBC) count. Urea, ALT, and ALB, with WBC demonstrating the most significant association. Further analysis within the female group revealed a compelling relationship between SUA levels and specific white blood cell subtypes, particularly neutrophils (Neu). This study revealed gender-specific associations between SUA levels and blood cell parameters in high-altitude areas. In males, RBC count may play a role in hyperuricemia, while in females, WBC count appears to be a significant factor. These findings contribute to our understanding of metabolic dynamics in high-altitude regions but require further research for comprehensive mechanistic insights.

Hippocampal neurometabolic and structural changes from pre-to post-COVID-19: A case-series study

BackgroundNeurological complications of the COVID-19 infection may be caused in part by local neurochemical and structural abnormalities that could not be detected during routine medical examinations. We examined within subject neurometabolic and structural brain alterations from pre-to post-COVID-19 in the hippocampal region of three elderly individuals (aged 63–68 years) who had a COVID-19 infection with mild symptoms. Patients were participating in an interventional study in which they were closely monitored at the time they were diagnosed with COVID-19. Patients 1 and 2 just completed 18–20 resistance training sessions prior to their diagnosis. Patient 3 was assigned to a non-training condition in the same study. MethodsWhole brain magnetic resonance imaging (MRI) images and proton magnetic resonance spectroscopy (1H-MRS) of the left hippocampus were collected before and after infection. Structural and spectroscopic imaging measures post-COVID-19 were contrasted to the pre-COVID-19 measures and were compared with values for Minimal Detectable Change at 95% (MDC95) and 90% (MDC90) confidence from a group of six elderly (aged 60–79 years) without COVID-19 that participated in the same study. ResultsAfter SARS-COV-2 infection, we observed a reduction of glutamate-glutamine (Glx) in Patients 1 and 2 (≥ 42.0%) and elevation of myo-inositol (mIns) and N-acetyl-aspartate (NAA) in Patient 3 (≥ 36.4%); all > MDC90. MRI findings showed increased (Patients 1 and 2) or unchanged (Patient 3) hippocampal volume. ConclusionsOverall, findings from this exploratory study suggest that mild COVID-19 infection could be associated with development of local neuroinflammation and reduced glutamate levels in the hippocampus. Our 1H-MRS findings may have clinical value for explaining chronic neurological and psychological complaints in COVID-19 long-haulers.

Locomotion Score and Postpartum Conception in Jersey Cows Raised under Hot-Humid Tropical Conditions: A Prospective Study.

Reproductive physiology is one of the first systems which is altered when an animal suffers from an imbalance. This is crucial in tropical dairy farming, where maintaining homeostasis and production is particularly demanding. Lameness is a disorder commonly identified by impaired walking, but its early diagnosis could reduce the negative repercussions on production, welfare, and postpartum conception. To evaluate the effect of lameness on postpartum conception, a prospective observational cohort study with a cross-sectional design was developed. Fifty-two Jersey milking cows raised under hot-humid tropical conditions were scored using a five-point locomotion scoring (LS) system (1-non-lame, 2-slightly lame, 3-moderately lame, 4-lame, and 5-severely lame), considering scores ≥ 3 to indicate clinical lameness. Inseminations per conception and days open (CCI) were registered. Inseminations were similar in animals scoring 1, 2, 3, and 5, while they increased in cows with a score of 4, which also increased their CCI along with animals that scored 5. Positive correlations were observed between LS and reproductive variables. The herd's conception rate was reduced from 45% to 21.8% in the presence of clinical lameness (score ≥ 3). Applying the LS system should be essential as part of routine medical examinations used to monitor dairy herds, and it becomes even more crucial under hot-humid tropical environments, where adverse conditions could rapidly aggravate the early stages of lameness and not only increase the costs of hoof care, but also delay fertility in cattle.
