Bacterial pathogens and antimicrobial susceptibility in ocular infections: A study at Boru-Meda General Hospital, Dessie, Ethiopia

IntroductionThe eye consists of both internal and external compartments. Several variables, including microbes, dust, and high temperatures can cause eye illnesses that can result in blindness. Bacterial eye infections continue to be a major cause of ocular morbidity and blindness, and their prevalence is periodically rising. The objective of the study was to detect bacterial pathogens and assess their susceptibility profiles to antibiotics in the ophthalmology unit of Boru-meda Hospital in Dessie, Ethiopia.MethodsA hospital-based cross-sectional study was conducted from February 1 to April 30, 2021, among 319 study participants with symptomatic ocular or peri-ocular infections who were enrolled using a consecutive sampling technique. After proper specimen collection, the specimen was immediately inoculated with chocolate, blood, and MacConkey agar. After pure colonies were obtained, they were identified using standard microbiological methods. The Kirby Bauer disk diffusion method was used to test antimicrobial susceptibility patterns, based on the guidelines of the Clinical and Laboratory Standards Institute.ResultsThe majority of participants developed conjunctivitis 126 (39.5%), followed by blepharitis 47 (14.73%), and dacryocystitis 45 (14.1%). Overall, 164 (51.4%) participants were culture positive, six (1.9%) participants had mixed bacterial isolates, giving a total of 170 bacterial isolates with an isolation rate of 53.3%. The predominant species was CoNS 47 (27.6%), followed by S. aureus 38 (22.4%) and Moraxella species 32 (18.8%). The overall Multi-Drug Resistance (MDR) rate was 62.9%, with 33 (44.6%) being gram-negative and 74 (77.1%) being gram-positive isolates.ConclusionConjunctivitis was the dominant clinical case and CoNS, was the predominant isolate. A higher rate of MDR isolates, particularly gram-positive ones, was observed. Efficient peri-ocular or ocular bacterial infection surveillance, including microbiological laboratory data, is necessary for monitoring disease trends.

The Impact of the NeuroAffective Relational Model (NARM) on Client Agency

ABSTRACT The NeuroAffective Relational Model (NARM) is a therapeutic model designed to treat Complex Post-Traumatic Stress Disorder (C-PTSD) integrating top-down (cognitive) and bottom-up (somatic) methods. Reinforcing client agency is one of the four pillars of the NARM model. This Interpretative Phenomenological Analysis investigated how NARM impacts client agency from the perspective of NARM Therapists. Fourteen NARM Therapists participated in a focus group to describe their work as a NARM trained trauma therapist treating clients who have experienced C-PTSD. The study revealed four themes that represent the phenomenon of client agency supported by the NARM model from the perspective of NARM Therapists. The emergent themes that support client agency include Connecting to Present Moment Awareness, Reflecting and Reinforcing Client Choices, Acknowledging Client Insight, and Contracting with the Client. Social workers can support clients experiencing C-PTSD by reinforcing client agency and utilizing trauma-informed approaches such as NARM to advance NASW standards for clinical social work practice standards one, two, and eleven (i.e. values and ethics, specialized practice skills, and interventions and professional development).

Current use of echocardiography in cardio-oncology: nationwide real-world data from an ANMCO/SIECVI joint survey.

The need for cardio-oncology competencies is constantly growing, and with the establishment of cardio-oncology services, cardiovascular imaging, particularly transthoracic echocardiography (TTE), has become pivotal in patients' management. However, care pathways for oncologic patients largely depend on local health structures' resources. This survey from Associazione Italiana Medici Cardiologi Ospedalieri and the Italian Society of Echocardiography and Cardiovascular Imaging aimed at investigating the use of echocardiography in cardio-oncology services and knowledge levels on cancer patients' care. Data were obtained via an electronic survey based on a structured questionnaire uploaded to the promoting societies' websites. Responses came from 159 centres with echocardiography. According to one-third of participating centres, workload related to cancer patients represented >30% of the total requests. The most common TTE indication (85%) was left ventricular ejection fraction (LVEF) evaluation. Many centres (55%) still assessed LVEF solely by bidimensional method or visual estimation in case of inadequate acoustic windows. At the same time, almost 40% of centres reported routinely using global longitudinal strain when feasible. We further performed a sub-analysis according to the presence (33%) or absence (77%) of dedicated cardio-oncologists, revealing significant differences in cardiovascular surveillance strategies and cardiotoxicity management. This survey on echocardiography practice for cancer patients reveals a significant gap between actual clinical practice and standards proposed by recommendations, underlying the need for stronger partnerships between cardiologists and oncologists and dedicated, well-structured cardio-oncology services.

The Role of Postbiotics in Asthma Treatment.

In recent years, there has been abundant research concerning human microbiome and its impact on the host's health. Studies have shown that not only the commensal bacteria itself, but also postbiotics, understood as inanimate microorganisms, possibly with the presence of their components, may themselves have an effect on various elements of human physiology. In this review, we take a closer look at the specific ways in which postbiotics can alter immune response in allergic asthma, which is one of the most prevalent allergic diseases in today's world and a serious subject of concern. Through altering patients' immune response, not only to allergens but also to pathogens, postbiotics could have a significant role in lowering the number of asthma exacerbations. We suggest that more profound research should be undertaken in order to launch postbiotics into clinical standards of asthma treatment, given the greatly promising findings in terms of their immunomodulating potential.

Evaluation of university and training standards in clinical perfusion, an European-wide survey.

Adequate theoretical and practical training of prospective clinical perfusionists is essential for maintaining clinical standards and ensuring patient safety during cardiac surgery procedures. Perfusion schools play a crucial role in establishing and maintaining higher education and training standards in clinical perfusion. The aim of this study is to obtain a comprehensive overview of European training standards in clinical perfusion in 2023. For this study, 53 perfusion schools in Europe were found and contacted, of which 30 (56.6%) responded, giving a sample size of n = 30, which were then included in the data analysis. The quantitative data of the survey are analysed using descriptive methods. The university and training standards in clinical perfusion in Europe vary in many respects. Starting with the entry criterion for studies (most frequently a required bachelor's degree 36.7% or 2nd most common an university entrance qualification 30%), the duration [from <12 months (13.3%) up to 36 months (13.3%)] and regarding the content of the teaching in clinical perfusion [<30 European Credit Transfer System (ECTS) (33.3%) and more than 180 ECTS (6.7%)]. The mean value for teaching in clinical perfusion content is 62.63 ECTS credits. The obtained results show important differences between countries and schools. As such, they form a valuable database for future discussions establishing a common European curriculum and training standards for perfusionists. For the generalizability of the results, further evaluations and larger samples are needed.

Phytotherapeutic potential of Artemisia ludoviciana and Cordia boissieri extracts against the dermatophyte Microsporum canis

Abstract Introduction Microsporum canis is a dermatophyte that mainly affects dogs and cats. However, it can be transmitted to humans by direct contact. This makes it one of the most frequent causative agents of dermatophytosis in humans, reflecting the frequent human close relationships with pets. Conventional treatment relies on antifungal pharmacological agents. However, errors in application have led to the occurrence of fungal resistance and toxic effects. Consequently, new therapeutic alternatives are needed for M. canis infections. Plant extracts have been explored as phytotherapeutics for the treatment of dermatophyte infections, which prompted an attempt to apply extracts of the ethnopharmacologically important plants Artemisia ludoviciana and Cordia boissieri. Material and Methods Methanolic extracts of these two plants were obtained using a Soxhlet method and were characterised by phytochemical screening. Extracts were evaluated against a M. canis commercial strain (ATCC-11621) using the microdilution method described in the Clinical and Laboratory Standards Institute protocol M38-A, determining its minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC). Subsequently, these concentrations were tested in a human keratinocyte human cell line. Results Artemisia ludoviciana and C. boissieri extracts showed MIC values of 2,500 and 1,250 µg/mL, and MFC values of 5,000 and 2,500 µg/mL against M. canis, respectively. These extracts did not inhibit HaCaT cell proliferation in vitro. Conclusion The evaluated extracts showed potential for the treatment of M. canis fungal infections. However, further studies on their phytochemical characterisation, purification, clinical safety and formulation are required.

Skipped wells and scientific error during fosfomycin agar dilution and broth microdilution lead to inconsistent minimal inhibitory concentrations and may be cause for reevaluating testing methods for Klebsiella pneumoniae.

Despite the first-line recommendation of fosfomycin for uncomplicated urinary tract infections (UTIs), there are pressing barriers for optimizing its use for the treatment of non-Escherichia coli Enterobacterales UTI. There are no approved breakpoints for oral use against other Enterobacterales, and the recommended agar dilution (AD) reference method for minimal inhibitory concentration (MIC) determination is largely impractical. Using 160 clinical Klebsiella pneumoniae isolates, we sought to understand rates of skipped wells and MIC imprecision in broth microdilution (BMD) and how that compares to rates of error using AD. Though the Clinical and Laboratory Standards Institute refers to the skipped well phenomena in their recommendation against the use of BMD, there is a paucity of data on its frequency. While AD and BMD produced similar MIC50/90 values (32/256 µg/mL for AD and 64/256 µg/mL for BMD), essential agreement was poor. No-growth wells at concentrations below the MIC occurred in up to 10.9% of wells at a given concentration, as the most frequent scientific error. Growth in concentrations above the measured MIC occurred in up to 3.3% of wells and was seen within three dilutions of the MIC for BMD. Observation of single colonies either at or beyond the measured MIC for AD was also common and occurred up to 8.3% and 2.5% of the time, respectively. The frequent scientific error in both testing methods should prompt re-evaluation of AD guidelines and expansion of MIC testing methods for fosfomycin susceptibility testing, as poor agreement with another method prone to scientific error should not be the main detractor from BMD use.IMPORTANCEDespite the recommendation of fosfomycin for uncomplicated urinary tract infections (UTIs), there are barriers for optimizing its use. There are no approved breakpoints for oral use against other Enterobacterales, and the recommended agar dilution (AD) reference method for MIC determination is largely impractical. The use of broth microdilution (BMD) for fosfomycin testing is not recommended by the Clinical and Laboratory Standards Institute due to unsatisfactory precision and skipped wells-occurrence of no-growth in a single well before the minimal inhibitory concentration (MIC)-and trailing endpoints. We sought to understand rates of skipped wells and growth at concentrations above measured MICs in BMD and how that compares to scientific error using AD. No-growth wells at concentrations below the MIC occurred in up to 10.9% of wells for BMD and single colonies at or beyond measured MICs for AD were also common. Frequent scientific error in both methods should prompt re-evaluation of both AD and BMD for fosfomycin susceptibility testing.

Evaluation of gradient diffusion in vitro susceptibility testing of Aerococcus urinae

ObjectiveAerococcus urinae antimicrobial susceptibility testing can be performed via broth microdilution with Mueller-Hinton broth supplemented with lysed horse blood. We sought to compare this with the commonly used gradient diffusion method. MethodsWe compared broth microdilution with Mueller-Hinton broth supplemented with lysed horse blood and gradient diffusion via Mueller-Hinton agar supplemented with sheep blood for 190 A. urinae isolates against 16 antimicrobials. ResultsNo antimicrobials demonstrated more than 90% essential and categorical agreement, and fewer than 3% demonstrated major and very major error rates. Trimethoprim-sulfamethoxazole demonstrated an 81% major error rate and ceftriaxone demonstrated a 76% very major error rate. Agar dilution with lysed horse blood was performed for trimethoprim-sulfamethoxazole against 94 isolates and showed 100% susceptibility, consistent with previous studies. ConclusionsGiven its limitations in detecting resistant strains, our findings cannot support the routine use of gradient diffusion with Mueller-Hinton agar supplemented with sheep blood for A. urinae in lieu of the Clinical and Laboratory Standards Institute method. Our results suggest that A. urinae is usually susceptible to penicillin, linezolid, tetracycline, and vancomycin. Future studies should evaluate alternative testing methods for clinical microbiology laboratories.

Stem-cell therapy in dermatology – Challenges and opportunities

The remarkable characteristics of stem cells (SCs), particularly their potency, capacity for self-renewal, and clonality, are well known. In recent years, there have been notable advancements in the field of cell therapy. Due to its distinctive qualities and versatility, this innovative therapy is already turning into a potentially helpful remedy for several diseases. Numerous dermatological problems, including autoimmune skin disorders, atopic dermatitis, skin aging, wound healing, scar repair, and many more, have been treated with SC-based therapies. Their application in regenerative medicine and esthetic dermatology is based on their capacity to self-renew and differentiate into distinct cell types. Given their abundance and relative simplicity of collecting adipose-derived SCs have shown to be particularly appealing in terms of appearance. SC therapy has demonstrated encouraging results in both skin regeneration and androgenetic alopecia treatment. Despite favorable preclinical evidence and clinical investigations, further randomized, controlled trials and treatment standardization are required to fully comprehend the role of SCs in the treatment of dermatological conditions, especially esthetics. The purpose of this article is to provide a general review of cell-based therapy, including its current uses, limits, and future possibilities in the field of dermatology.

Increasing Resistance of Nosocomial and Community-Acquired Escherichia coli in Clinical Samples from Hospitals and Clinics in Sana’a City

Antimicrobial resistance in Escherichia coli presents a global challenge associated with nosocomial infections and increased mortality rates. Understanding resistance profiles is crucial for guiding treatment strategies and ensuring effective antibiotic use. This study aimed to investigate the prevalence and in vitro resistance of E. coli to community-acquired and nosocomial infections. Various clinical samples from 700 patients were cultured on MacConkey’s medium and blood agar. The disk diffusion method was used to determine the antibiotic susceptibility profile of the E. coli isolates following the guidelines of the Clinical and Laboratory Standards Institute (CLSI). Urine, pus, seminal fluid, vaginal swabs, and other body fluids were among the clinical samples analyzed. Of the 112 E. coli isolates, 48.2% were from inpatients and 51.8% were from outpatients, with the majority (66%) isolated from urine samples. Higher resistance levels were observed in the urinary isolates than that in the previously recorded data from the same institutions. Notably, isolates exhibited high resistance to penicillin (98.2%), ampicillin (97.3%), first-generation cephalosporins (90.2%), erythromycin (72.2%), and roxithromycin (95.4%), whereas lower resistance was noted against piperacillin-tazobactam (25.0%), nitrofurantoin (12.5%), and imipenem (9.8%). The overall multidrug resistance rate was 62.5%, with higher rates observed in nosocomial infections (70%) compared to community-acquired isolates (55.6%). However, this difference was not statistically significant (p&gt;0.05). This study underscores the prevalence of E. coli isolates (27.0%) and highlights the concerning level of resistance, particularly to older antibiotics. These findings emphasize the importance of judicious antibiotic use and ongoing surveillance.

Phytochemical Composition and Antimicrobial and Antibiofilm Effect of Myrciaria cauliflora Hydroethanolic Extract against Staphylococcus aureus and Acinetobacter baumannii.

Staphylococcus aureus and Acinetobacter baumannii are opportunistic pathogens, and both are involved in different oral infections. This work aimed to analyze the phytochemical composition of Myrciaria cauliflora hydroethanolic extract and to evaluate its antimicrobial and antibiofilm action against Staphylococcus aureus (ATCC 6538) and Acinetobacter baumannii (ATCC 19606; multi-resistant clinical strains 58004, 50098, 566006, and H557). Myrciaria cauliflora hydroethanolic extract was prepared, and the content of soluble solids, flavonoids, and phenols was quantified. High-performance liquid chromatography (HPLC) was performed later. The minimum inhibitory concentration was determined using the broth microdilution method according to the Clinical and Laboratory Standards Institute, standard M7-A6, and subsequently, its minimum bactericidal concentration was determined. Then, the most effective concentrations were analyzed against biofilms. Statistical analysis was performed using the ANOVA method with Tukey's test. The soluble solids content in the prepared hydroethanolic extract of M. cauliflora was 2.22%. Additionally, the total flavonoid content, measured using the quercetin standard curve, was 0.040 mg/mL. Furthermore, the total phenol content, determined using the gallic acid standard curve, was 0.729 mg/mL. HPLC analysis presented peaks of gallic acid (11.80 m), p-coumaric acid (12.09 m), cinnamic acid derivative (19.02 m), and ellagic acid (29.83 m). The extract demonstrated antimicrobial and antibiofilm action against all tested strains. However, the most effective antibacterial concentration against all the tested bacteria was 5.55 mg/mL. Therefore, these chemical components justify that M. cauliflora hydroethanolic extract is effective in reducing biofilm formation in S. aureus (standard strain) and A. baumannii (standard and clinical strains).

Canada's Medical Assistance in Dying System can Enable Healthcare Serial Killing.

The Canadian approach to assisted dying, Medical Assistance in Dying (MAiD), as of early 2024, is assessed for its ability to protect patients from criminal healthcare serial killing (HSK) to evaluate the strength of its safeguards. MAiD occurs through euthanasia or self-administered assisted suicide (EAS) and is legal or considered in many countries and jurisdictions. Clinicians involved in HSK typically target patients with the same clinical features as MAiD-eligible patients. They may draw on similar rationales, e.g., to end perceived patient suffering and provide pleasure for the clinician. HSK can remain undetected or unconfirmed for considerable periods owing to a lack of staff background checks, poor surveillance and oversight, and a failure by authorities to act on concerns from colleagues, patients, or witnesses. The Canadian MAiD system, effectively euthanasia-based, has similar features with added opportunities for killing afforded by clinicians' exemption from criminal culpability for homicide and assisted suicide offences amid broad patient eligibility criteria. An assessment of the Canadian model offers insights for enhancing safeguards and detecting abuses in there and other jurisdictions with or considering legal EAS. Short of an unlikely recriminalization of EAS, better clinical safeguarding measures, standards, vetting and training of those involved in MAiD, and a radical restructuring of its oversight and delivery can help mitigate the possibility of abuses in a system mandated to accommodate homicidal clinicians.

Optimization of Sodium Iodide-Based Root Filling Material for Clinical Applications: Enhancing Physicochemical Properties.

Premature loss of root canal-treated primary teeth has long been a concern in dentistry. To address this, researchers developed a sodium iodide-based root canal-filling material as an alternative to traditional iodoform-based materials. The goal of this study was to improve the physicochemical properties of the sodium iodide-based material to meet clinical use standards. To resolve high solubility issues in the initial formulation, researchers adjusted component ratios and added new ingredients, resulting in a new paste called L5. This study compared L5 with L0 (identical composition minus lanolin) and Vitapex as controls, conducting physicochemical and antibacterial tests. Results showed that L5 met all ISO 6876 standards, demonstrated easier injection and irrigation properties than Vitapex, and exhibited comparable antibacterial efficacy to Vitapex, which is currently used clinically. The researchers conclude that if biological stability is further verified, L5 could potentially be presented as a new option for root canal-filling materials in primary teeth.

Bone and joint infections. Algorithms of antibiotic therapy in surgical practice

Bone and joint infections such as osteomyelitis, septic arthritis, etc. are serious medical conditions that require prompt and effective treatment. Without proper intervention, these infections can lead to significant complications, including chronic pain, deformity, loss of function, and even systemic complications such as sepsis. Antibiotic therapy plays a k ey role in the management of these infections making it possible to prevent serious complications, preser ve limb function, reduce treatment costs, and improve clinical outcomes. The ar ticle discusses the basic principles and algorithms for antibacterial treatment of infection in the given localization, taking into account modern clinical recommendations and standards of pharmacotherapy. Timely diagno - sis and adequate treatment can reduce the risk of complications and improve the prognosis in patients with bone and joint infections. The rational use of antibiotics is also a par t of the fight against developing microbial resistance, which is of great importance for public health.

Antibiotic therapy for skin and soft tissue infections. current algorithms

Antibiotic therapy for infectious lesions of the skin and soft tissues requires a careful approach to ensure the effectiveness of treatment and prevent the development of resistance. The article discusses the basic principles and algorithms of antibacterial treatment for skin and soft tissue infections, taking into account modern clinical recommendations and standards of pharmaco - therapy. The initial choice of antibiotic is of ten based on the t ypical pathogens associated with the infection (most commonly Staphylococcus aureus and Streptococcus pyogenes). If MRSA (methicillin-resistant Staphylococcus aureus) or other resistant microorganisms are suspected, they must be taken into account in the choice of initial therapy. A fter receiving the results of culture studies and determining the sensitivit y of microorganisms, therapy should be adjusted. It is essential to maintain the antibiotic concentration at a level sufficient to eliminate the infection and prevent recurrence. The choice of antibiotic should take into account the side effects and possible interactions with other drugs.

Impact of hematocrit levels on the accuracy of specific blood glucose meters: Ahospital-based study.

Blood glucose meters are commonly used at the bedside, but most of the meters used in Hung Vuong Hospital (Ho Chi Minh City, Vietnam) are built for self-monitoring and might not be suitable for determining glucose levels in patients. In this study, we aimed to validate the performance of six frequently used meters in our hospital using the Clinical & Laboratory Standards Institute (CLSI) standard, and investigate the hematocrit impact on the accuracy of these meters. A total of 135 pregnant women who underwent a 75-g oral glucose tolerance test consented to participate in the study at Hung Vuong Hospital. Whole blood glucose levels were measured in duplicate using meters, and hematocrit levels were measured using an Alinity h-series analyzer. Within 5 min, plasma glucose levels were measured twice in a row using the Cobas c502 reference analyzer. For accuracy and precision, the hematocrit effect was assed using CLSI POCT12-A3. Out of six evaluated meters, three meters qualified. For CLSI criterion at glucose concentration of 5.55 mmol/L, Accu-Chek Inform II, Accu-Chek Performa and OneTouch VerioVue achieved 97.31%, 98.08% and 99.62%, respectively. For CLSI criterion at 4.17 mmol/L, these three achieved 100%. Accu-Chek Inform II and Accu-Chek Performa showed an inverse correlation between glucose level and hematocrit with slopes of -0.500 (95% confidence interval -0.678 to -0.322) and -0.396 (95% confidence interval -0.569 to -0.224), whereas OneTouch VerioVue was not affected by hematocrit, with a slope of 0.207 (95% confidence interval -0.026 to 0.440). Blood glucose meters' measurements can be affected by hematocrit, and might provide readings not within an acceptable bias. Medical organizations need to verify or validate before using on patients.

Age- and Gender-Specific Reference Intervals for the Fasting Serum Lipid Levels in a Pediatric Population Aged 0-＜15 Years in Nanjing, China.

The lipid reference intervals (RIs) that are currently used for children in China are not based on studies of the local population and normally do not consider age or gender differences. This study aimed to establish age- and sex-specific RIs for the fasting serum lipid levels in the pediatric population aged 0 - 15 years in Nanjing, China. 5,866 children aged 3 days to ＜15 years were recruited to establish serum lipid RIs, and the triglyceride (TG), total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C) levels were analyzed using the Roche cobas702 automatic biochemical analyzer. Low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (nHDL-C) levels were calculated (LDL-C=TC-HDL-C-TG/5, and nHDL-C=TC-HDL-C). Smoothed percentile curves for the boys and girls were generated using the LMS method. Age- and sex-specific RIs were the determined according to the methods recommended by the Clinical and Laboratory Standards Institute EP28-A3c guidelines. This study showed that the serum lipid levels varied considerably throughout childhood and adolescence, with sex differences, especially in infants aged less than 2 years and puberty. Based on the Harris-Boyd method, sex partitions were required for ages ＜6 months in the TC indicator and for ages ≤ 28 days in LDL-C and nHDL-C. Age partitions were also required for all serum lipid parameters. We established age- and sex-specific RIs for TG, TC, HDL-C, LDL-C, and nHDL-C parameters in children aged 0 days to ＜15 years in Nanjing, China. These data are thus considered to be useful for the screening of dyslipidemia in children and adolescents.

Implementation of a Mental Health Objective Structured Clinical Examination (OSCE) Using Standards of Best Practice.

The objective structured clinical examination (OSCE) is effective for the evaluation of clinical competence. Studies examining the use of OSCEs in undergraduate mental health nursing education in the United States are limited. A pilot study and a follow-up study were conducted to establish the reliability and validity of a mental health OSCE to evaluate the clinical competence of prelicensure nursing students. International Nursing Association for Clinical Simulation and Learning Standards of Best Practice were used to guide the design and implementation. Results from both studies provide evidence for the use of OSCE in undergraduate mental health nursing education.

Ultrasound Image Temperature Monitoring Based on a Temporal-Informed Neural Network.

Real-time and accurate temperature monitoring during microwave hyperthermia (MH) remains a critical challenge for ensuring treatment efficacy and patient safety. This study presents a novel approach to simulate real MH and precisely determine the temperature of the target region within biological tissues using a temporal-informed neural network. We conducted MH experiments on 30 sets of phantoms and 10 sets of ex vivo pork tissues. We proposed a novel perspective: the evolving tissue responses to continuous electromagnetic radiation stimulation are a joint evolution in temporal and spatial dimensions. Our model leverages TimesNet to extract periodic features and Cloblock to capture global information relevance in two-dimensional periodic vectors from ultrasound images. By assimilating more ultrasound temporal data, our model improves temperature-estimation accuracy. In the temperature range 25-65 °C, our neural network achieved temperature-estimation root mean squared errors of approximately 0.886 °C and 0.419 °C for fresh ex vivo pork tissue and phantoms, respectively. The proposed temporal-informed neural network has a modest parameter count, rendering it suitable for deployment on ultrasound mobile devices. Furthermore, it achieves temperature accuracy close to that prescribed by clinical standards, making it effective for non-destructive temperature monitoring during MH of biological tissues.
