Authors: Li Xingyuan , Liu Ke , Lang Yanlin , Chai Zhonglin , Liu Fang
Published: August 2024

BACKGROUND

Artificial intelligence (AI) has shown great promise in assisting medical diagnosis, but its application in renal pathology remains limited.

OBJECTIVE

We evaluated the performance of an advanced AI language model, Claude 3 Opus (Anthropic), in generating diagnostic descriptions for renal pathological images.

METHODS

We carefully curated a dataset of 100 representative renal pathological images from the Diagnostic Atlas of Renal Pathology (3rd edition). The image selection aimed to cover a wide spectrum of common renal diseases, ensuring a balanced and comprehensive dataset. Claude 3 Opus generated diagnostic descriptions for each image, which were scored by 2 pathologists on clinical relevance, accuracy, fluency, completeness, and overall value.

RESULTS

Claude 3 Opus achieved a high mean score in language fluency (3.86) but lower scores in clinical relevance (1.75), accuracy (1.55), completeness (2.01), and overall value (1.75). Performance varied across disease types. Interrater agreement was substantial for relevance (κ=0.627) and overall value (κ=0.589) and moderate for accuracy (κ=0.485) and completeness (κ=0.458).

CONCLUSIONS

Claude 3 Opus shows potential in generating fluent renal pathology descriptions but needs improvement in accuracy and clinical value. The AI’s performance varied across disease types. Addressing the limitations of single-source data and incorporating comparative analyses with other AI approaches are essential steps for future research. Further optimization and validation are needed for clinical applications.

Published: August 2024

BACKGROUND

Understanding the dementia disease trajectory and clinical practice patterns in outpatient settings is vital for effective management. Knowledge about the path from initial memory loss complaints to dementia diagnosis remains limited

OBJECTIVE

This study aims to 1) determine the time intervals between initial memory loss complaints and dementia diagnosis in outpatient care, 2) assess the proportion of patients receiving cognition-enhancing medication prior to dementia diagnosis, and 3) identify patient and provider characteristics that influence the time between memory complaints and diagnosis, and the prescription of cognition-enhancing medication.

METHODS

This retrospective cohort study utilized a large outpatient EHR database from the University of Connecticut Health Center, covering 2010-2018, with a cohort of 581 outpatients. We employed a customized deep learning-based natural language processing (NLP) pipeline to extract clinical information from electronic health record (EHR) data, focusing on cognition-related symptoms, primary caregiver relation, and medication usage. We applied descriptive statistics, linear, and logistic regression for analysis.

RESULTS

The NLP pipeline showed precision, recall, and F1 scores of 0.97, 0.93, and 0.95, respectively. The median time from the first memory loss complaint to dementia diagnosis was 342 days. Factors such as the location of initial complaints and diagnosis, and primary caregiver relationships significantly affected this interval. Around 25% of patients were prescribed cognition-enhancing medication before diagnosis, with the number of complaints influencing medication usage

CONCLUSIONS

Our NLP-guided analysis provided insights into the clinical pathways from memory complaints to dementia diagnosis and medication practices, which can enhance patient care and decision-making in outpatient settings.
Association of possible sarcopenia, sarcopenia and sarcopenic obesity with multimorbidity among middle-aged and older adults: Findings from the China health and retirement longitudinal study (Preprint)
Authors: Zheng Xiaowei , Wu Wenyan , Ma Tao
Published: August 2024

BACKGROUND

The association between possible sarcopenia, sarcopenia and sarcopenic obesity on multimorbidity risk remains poorly investigated.

OBJECTIVE

We aimed to evaluate the associations between possible sarcopenia, sarcopenia and sarcopenic obesity on multimorbidity prevalence and incidence in middle-aged and older Chinese population.

METHODS

A total of 13,036 participants from the China Health and Retirement Longitudinal Study 2011 were included in cross-sectional analyses. 5,771 participants were including in longitudinal analyses and were followed up in 2018. Sarcopenia status was defined according to the Asian Working Group for Sarcopenia 2019 (AWGS 2019) criteria. Obesity was defined according to body mass index.

RESULTS

In cross-sectional analyses, possible sarcopenia, sarcopenia and sarcopenic obesity were significantly associated with higher multimorbidity prevalence. During the 7 years of follow-up, 2295(39.77%) participants with new-onset multimorbidity were identified. Compared with participants without sarcopenia or obesity, a greater increase in the risk of multimorbidity incidence was found among participants with obesity only (OR=1.39, 1.21-1.59), sarcopenia only (OR=1.45, 1.35-1.58) and sarcopenic obesity (OR=2.42, 2.03-2.89). Both pre-sarcopenia, sarcopenia and sarcopenic obesity were positively related to an increased number of morbidities.

CONCLUSIONS

Pre-sarcopenia, sarcopenia and sarcopenic obesity were associated with higher multimorbidity prevalence and incidence. Our findings provide important implications for screening and preventing possible sarcopenia, sarcopenia and obesity, which may be beneficial in reducing chronic disease burden.

Published: August 2024

BACKGROUND

Mild cognitive impairment is a transitional stage between normal cognitive aging and dementia. Identifying individuals at the preMCI stage, prior to the onset of mild cognitive decline, can be pivotal for early interventions aimed to reduce the progression neurodegeneration.

OBJECTIVE

The objective of this study is to develop convolutional neural networks trained on fluid attenuated inversion recovery magnetic resonance imaging for classification of preMCI in an imbalanced cohort of 350 participants.

METHODS

A DenseNet 264 convolutional neural network was trained on an imbalanced dataset of 350 participants with a dataset split into 64%, training, 16% validation, and 20% testing sets. Training was conducted with a batch size=70, epoch=200, processing images resized to a uniform dimension of 128×128×128 voxels, and optimizer=Adam. The optimization of our network was conducted using the Adam Optimizer with a learning rate of 10-3 and a weight decay of 5-4. Data augmentation strategy included Random affine transformation, random rotation across an axis, and random Gaussian noise on each image during training.

RESULTS

Mean age of the participants was 71.6 (SD 5.14); the average educational attainment was 16.3 years (SD 2.39). The mean MoCA score was 26.7 (SD 1.93). Our DenseNet mode achieved R2=0.146 and RMSE=0.569.

CONCLUSIONS

These findings underscore the potential of brain imaging and DL to identify this at-risk population, offering a promising tool for early detection and potential personalized preventative strategies against cognitive decline. Further research is warranted to improve upon the results to validate these findings in a larger, more diverse population.

Published: August 2024

In recent years, the search for new anticancer drugs from local plants in Indonesia has become an interesting topic for research. One of the typical Indonesian local plants that have been used by the community as an anticancer traditional medicine (jamu) is Spatholobus littoralis Hassk (SLH) or better known as Bajakah. The native Dayak people of Kalimantan have used it for years for the treatment of breast cancer. In this study, the separation of single compounds from the ethyl acetate fraction of SLH stems was carried out, their molecular structure was analyzed, and anticancer bioactivity was tested. The isolation used the preparative HPLC method. The elucidation of the isolates from the ethyl acetat fraction used LCMS-MS, FTIR, and NMR. Anticancer bioactivity was determined using the MTT bioassay. The result is the acquisition of two isolates; it has been predicted that both are pseudobaptinin. The anticancer IC50 of the pseudobaptinin was 62.85 ppm, and Pseudobaptinin with impurities was 145.60 ppm.

Published: August 2024

Typhoid fever is caused by consuming food or water contaminated with Salmonella typhi. The disease develops from bacterial infection through the consumption of contaminated sustenance and drink. The bacterium can cause bacteremia, which is bacteria living in the blood, penetrating the mucosal epithelium of the small intestine and entering the lymphatic flow. Therefore, this study aimed to assess the potential inhibitory effect of ethanol extracts derived from stems of Eurycoma longifolia (pasak bumi) on the growth of Salmonella typhi bacteria. Compounds such as alkaloids, saponins, flavonoids, terpenoids, and tannins in pasak bumi stems possessed antibacterial properties. Extracts were made using 96% ethanol at varying concentrations (10%, 20%, 30%, 40%, 50%) with distilled water and chloramphenicol as negative and positive control. The result showed that pasak bumi stem extracts inhibited Salmonella typhi, with increasing efficacy at higher concentrations and statistical analysis reported significant differences between all treatment groups (p<0.001). Average zone diameter was 0 mm and 23.10 mm for negative and positive control, as well as 2.75 mm, 4.10 mm, 5.24 mm, 6.98 mm, and 8.55 mm for 10%, 20%, 30%, 40% and 50% extracts, respectively. This study provided verification of antibacterial effects of pasak bumi stem ethanol extracts against Salmonella typhi.

Manejo multimodal de aneurisma cirsoideo. Reporte de un caso y revisión de la literatura
Authors: Wong del Pino Andrea Mei Lay , Vázquez Nieves José Roberto
Published: August 2024

Scalp arteriovenous malformations (AVMs), commonly known as cirsoid aneurysms, are complex collections of arteries and veins that communicate directly. It has been postulated that AVMs occur both through the activation of inactive fistulous lesions and through the formation of new fistulous vascular channels through the canalization of injured vessels. Depending on their size and complexity, a variety of strategies can be used to treat them. The case of a 53-year-old male is presented who came for evaluation due to an increase in the volume of a pulsating lesion that extended from the right parietotemporal region accompanied by holocraneal headache and tinnitus. A cerebral angiotomography was performed in which a lesion composed of ectatic serpentine images, with a right extracranial location, subsequently diagnostic cerebral angiography was performed demonstrating a right frontoparietal fistulous and plexiform arteriovenous shunt fed by afferents from the right superficial temporal, posterior auricular, occipital and middle meningeal arteries, with drainage through a varicose and ectatic vein towards the external jugular vein. An endovascular embolization of the arteriovenous shunt was performed via the femoral route in two stages, achieving a “pressure cooker” construction to perform the injection of embolizing fluid and have a subtotal embolization of 93%, with this it was possible to perform a microsurgical resection with a right fronto-parietal-temporal approach resecting the deepest part, leaving the scalp with embolized vessels without resecting. To close the surgical wound, a simple flap rotation was performed to cover the skin defect derived from its resection. The patient underwent post-resection cerebral panangiography, identifying the absence of arteriovenous shunt. Depending on the extent and anatomical complexity of the malformation, clinical manifestations may vary. More than 80% of AVMs will be present at birth and the rest may develop after head trauma or surgical interventions. Appropriate therapeutic intervention is needed through selective angiography, during which endovascular embolization of the major feeding vessels can be performed before open surgical intervention. Volume-based three-dimensional computed tomography reconstructions can be used for further planning. Surgical reduction of post-embolization arterial supply will reduce intraoperative hemorrhage, facilitating total surgical resection. Removal can result in large, full-thickness skin defects that may be difficult to reconstruct without compromising functional and cosmetic results.

India is facing a new wave of Lumpy skin disease outbreaks since May 2022, spreading in more than 22 states and causing morbidity to more than 29 lakh animals and mortality to more than 2 lakh animals. Lack of specific antiviral treatment restores symptomatic therapeutic interventions. However, in the advent of large no. of cases and severity of disease, investigations on specific antiviral drugs are imperative. This scientific study was conducted on a group of LSD-affected cattle (n = 40) from the trans-Himalayan region of Kashmir (Jammu and Kashmir). The affected cattle were subjected to different treatments, including acyclovir (n = 27), symptomatic treatment (n = 7), and ivermectin (n = 6), along with supportive drugs. The animals were carefully monitored and compared both within and between groups at various intervals (0-96 hr) using a two-way analysis of variance (ANOVA). Significant (P ≤ 0.05) improvement in regaining rectal temperature, respiration rate, and heart rate was noted 48 hours after treatment in a group of LSD-affected animals (n = 27) treated with acyclovir at a dose rate of 1 mg/kg body weight (small cattle) to 1.5 mg/kg (large cattle) intravenously in 500 ml normal saline along with supportive drugs including enrofloxacin (2.5 mg/kg), combination of meloxicam (0.25 mg/kg) and paracetamol (7.5 mg/kg) and pheniramine maleate (0.5 mg/kg) all intramuscularly, compared to group of LSD affected cattle (n = 6) treated with ivermectin (0.2 mg/kg subcutaneously) and supportive drugs and another group of LSD affected cattle (n = 7) treated symptomatically with only supportive drugs. Acyclovir treated group showed a significant (P ≤ 0.05) decrease in total leucocyte count, lymphocyte, and basophil count from 0 hour to 96 hour of treatment (23.00 ± 0.534 to 5.59 ± 0.208; 13.97 ± 0.310 to 3.43 ± 0.126; 0.11 ± 0.003 to 0.03 ± 0.001 respectively). Significant (P ≤ 0.05) decrease in total oxidative status (TOS: 73.31%) and increase in total antioxidant status (TAS: 59.9%) was observed in acyclovir treated group followed by ivermectin treated group (TOS: 68.05% and TAS: 27.16%) compared to symptomatically treated group (TOS: 42.41% and TAS: 18.75%). Acyclovir being comparatively more specific antiviral agent than ivermectin may have helped in amelioration of clinical severity and regaining of normal physiological, hematological, and oxidative indices in LSD-affected animals. The current study demonstrates expedited recovery, diminished clinical severity, and re-establishment of physiological, hematological and oxidative markers in animals subjected to acyclovir treatment, followed by animals administered with ivermectin, when compared to animals receiving symptomatic treatment. However, further studies are required to investigate safety or adverse effects, if any.

Objective

To assess the corrosion products and cytotoxicity of generic and proprietary fixed lingual retainers (FLRs).

Materials and Methods

Seven FLRs were investigated. Wires were submersed in solution for 34 days, at 37°C, under constant agitation. A proportion of this solution was analyzed to determine the concentration of metallic ions leaching off the wires. The remainder was diluted to 5%, 10% and 20% followed by exposure to human gingival fibroblasts and analysis of cytotoxicity of the wires.

Results

Three wires (Dentaflex, Universal, and AZDent) released excessive concentrations of lead, two wires (MeshMark and Orthoflex) released excessive concentrations of nickel, and one wire (Universal) released excessive concentrations of molybdenum into solution. No statistically significant difference was found between the wires analyzed (P = .24). Slight cytotoxicity was noted in only one wire (Dentaflex) at a 20% dilution of eluent. This was also the wire which released the highest concentration of lead into solution. All other wires, at all concentrations, were deemed noncytotoxic, but five samples overall were deemed statistically significant (P < .0024). A statistically significant difference existed between wires (P = .013) and concentrations analyzed (P < .001).

Conclusions

Metals were released in differing quantities from all wires, with some elemental concentrations measuring more than that deemed acceptable in drinking water in Australia. A trend toward increased cell viability across samples was found with only one demonstrating cytotoxicity. There was no indication that generic FLRs were more or less biocompatible than their proprietary counterparts.

A field experiment was conducted at the Research Farm of the Department of Tea Husbandry and Technology, Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya, Palampur (Himachal Pradesh) in pre-monsoon, monsoon and post-monsoon i.e., from March, 2021 to November, 2021. The objective was to assess the impact of organic nutrient inputs on Tea (Camellia sinensis L. O. Kuntze). The experiment comprised of 10 treatments with the organic treatment include application of different nitrogen sources, viz farmyard manure; vermicompost; jeevamrit and vermiwash. The experiment included ten treatments, including a control group, FYM (Farm Yard Manure) @ 20 t ha-1, vermicompost @ 10 t ha-1, split doses of FYM @ 10 t ha-1+10 t ha-1, split doses of vermicompost @ 5 t ha-1+5 t ha-1, FYM @ 20 t ha-1+Jeevamrit @ 10%, vermicompost @ 10 t ha-1+Jeevamrit @10%, FYM @ 20 t ha-1+vermiwash @ 10%, vermicompost @ 10 t ha-1+vermiwash @ 10% and Jeevamrit @ 10%. The experiment was designed following a Randomized Block Design (RBD) with three replications. The soil of experiment field was acidic in nature, silty clay loam in texture, low in Nitrogen, medium in Phosphorus and Potassium. The results showed that the growth, yield attributes and overall tea yield increased significantly with the application of vermicompost @ 10 t ha-1+Jeevamrit @ 10%. Furthermore, this treatment exhibited notably higher gross returns, net returns and additional net returns compared to the control group.

Biodiversity and local wisdom in mangrove ethnopharmacology are essential to study as a basis for conservation and health development. The study objectives were determining mangroves’ diversity and distribution, their use as herbal medicine, and their trusted medical properties. Vegetation analysis was employed to study the mangrove diversity. An interview and observation were conducted to study mangrove utilization. Mangrove diversity was determined by examining the diversity index. Mangrove utilization was determined by descriptive comparative analysis and calculating species use value, plant part value, and fidelity level. Total 28 species of mangroves from 15 families in Lampung. The highest mangrove diversity is in Lampung Timur (22 species; Shannon Index (H') = 1.93), followed by Pesawaran (21 species; H' = 1.96), Tulang Bawang (12 species; H' = 1.24), and Lampung Selatan (11 species H' = 0.90). Surprisingly, a species was used for different purposes in different areas. S. caeseolaris has the highest species use value of 0.1591. Leaves have the highest plant part value of 58%. R. apiculata, as an antiseptic, and S. caseolaris, as an antioxidant, have the highest fidelity level, 14%. Eight mangrove species trusted by the community have ten medical properties. This finding could be the basis for scientific studies to find new sources of medicine.

Fires at the petrochemical industry facilities cause harm to human life and health and significant economic and environmental damage. Accidents associated with ignitions at oil and petrochemical storage facilities in 2018–2022, resulted in injuries of 21 persons, and 10 fatalities; the total economic damage exceeded 1.5 billion rubles. One of the causes of fires is the spontaneous combustion of pyrophoric corrosive deposits (17 %). As a result of the reaction of the interaction of iron disulfide with oxygen in the air, pyrophoric corrosive deposits ignite. Large-scale steel equipment containing sulfurous oil is exposed during operation to corrosive and mechanical wear, risk of fires, and explosions. One of the protection methods of oil and gas equipment against corrosion and pyrophoric formations is surface treatment with paint anticorrosive coating. Modern paint coatings proved to be ineffective in ensuring anticorrosive protection of metal equipment. The main objective of the article is to study various options of metal surface treatment by electrochemical methods with the following comparison of their protective ability. The efficiency (isolating ability) of various treatments of St3 steel has been analyzed. Based on the results of electrochemical corrosive studies, chronogalvanometric curves have been built. Therefore, to determine the efficiency of the protective effect of anticorrosive paint coatings, the accelerated corrosive-electrochemical method is recommended. For the treatment of the oil equipment surface, the anticorrosive paint coating containing the following layers: inhibitor (urotropinу solution); primer (sodium polyacrylate, ethyl alcohol); and two layers of sodium polyacrylate, have been proposed to use. The application of this protective coating will ensure a fault-free mode of operation of oil equipment for more than 10 years without coating replacement. This will guarantee the safe work of employees at the petrochemical industry facilities.
