Submyocardial Pacing Threshold Distribution During Cold Saline Application; Exploring Reversible Arrhythmia Inhibition.

Cold saline application through an irrigation catheter may induce reversible inhibition of submyocardial excitation, which may be used to identify in advance an ideal site for radiofrequency (RF) energy delivery around delicate areas. An open irrigation catheter was positioned vertically or parallel with 10-g contact on coronary perfusing porcine hearts and the contacted myocardium was cooled by cold saline at 4°C (20mL/min). A temperature electrode was inserted 2mm below the myocardial surface (intra-myocardial temperature at approximately 2 mm below the surface [Temp-BS]). Pacing threshold inside the ventricular wall was measured using aneight-pole electrode plunge needle inserted 5-8mm close to the ablation catheter, and percent increase of the pacing threshold by the cold saline application (%increase-PT) was calculated. During cooling, pacing at 10V from the myocardial surface interrupted constant capture in 7/10 experiments in vertical and in 9/10 experiments in parallel ablation catheter contact. Minimum Temp-BS was not different in both catheter contact positions (25.9±4.0°C in vertical vs. 25.4±2.6°C in parallel). Large % increase-PT on the surface myocardium decreased as the myocardial depth became deeper, and > 150% increase was at a depth approximately 2-3mm from the surface and > 120% increase around 6-7mm from the surface. After cessation of cold saline application, the increased %increase-PT recovered to the pre-cooling values. Cold saline application through an irrigation catheter reversibly inhibited submyocardial excitation. This simple method may have the potential to pre-determine the ideal ablation site in sensitive areas of the heart, although further studies and technological adjustments are required before clinical use.

Influence of hydrotherapy on change in weight: a narrative review.

There is a growing interest in weight loss in today's world. Environmental factors are the main contributor behind the rapidly spreading obesity during pandemic. Exercise and diet are two controllable elements that significantly effect on energy balance., The use of cold application such as cold-water immersion, cold abdominal pack, balneotherapy, cold exposure, water drinking, steam, and sauna sessions, has shown a positive impact in weight management. This review explains the mechanism and various types of hydrotherapy applications managing weight through thermogenesis and non-shivering thermogenic pathways, which involve the brown adipose tissue, and dependent on uncoupling protein 1 (UCP1) in the inner mitochondrial membrane. Hence the present literature provides insight into use of hydrotherapy applications for future direction in weight management.

Generalisation of the hydrodynamics model method for hot and cold strip rolling application

The present work constitutes a generalization of the hydrodynamic model used to predict the pressures and the rolling speeds during the hot rolling of aluminum and copper strips. The hydrodynamic model with a linear behavior (Newton viscous) of the materials shows good predictions in the literature but its applicability is questionable in non-linear cases, when the materials exhibit viscoplastic or plastic behavior. This work extends the model to accommodate non-linear cases commonly encountered in rolling models (viscoplastic and plastic behaviors). The obtained results are in good agreement with experimental data from the literature. The validated model can, therefore, be considered an enhanced hydrodynamic model for predicting pressures and velocities during both hot and cold rolling of thin strips.

The effect of three different nonpharmacological methods on cannulation success during peripheral intravenous catheter placement in the emergency unit: a randomized controlled trial

BackgroundPeripheral intravenous catheterization is frequently performed in emergency units, but it is a procedure which is difficult for healthcare professionals and painful for patients. The primary objective of the present study was to examine the effect on venous dilation, procedure duration and pain severity of local heat, cold and vibration applications performed on the intervention area before peripheral intravenous catheterization in adults. The second objective of the study was to examine the effects of age and gender variables on the participants’ pain intensity levels.MethodsA single-blinded randomized controlled trial. The study included 120 adults who were randomly selected between March and August 2023. One application group (n = 30) received local heat application, one group (n = 30) received local cold application, and one (n = 30) received local vibration using the Buzzy® device. The applications, to the site of the peripheral intravenous catheterization, lasted one minute. The control group (n = 30) received standard peripheral intravenous catheterization application. The groups’ vein dilation was assessed with the vein assessment scale, pain felt during catheterization with the visual analog scale, and the duration of the procedure with a chronometer.ResultsIt was found that the venous dilation of the cold application group was significantly higher (p = 0.010, p = 0.015 respectively) and procedure duration was shorter (p = 0.013, p < 0.001 respectively) than that of the heat and vibration application groups, and its pain severity was significantly lower (p = 0.002, p = 0.001 and p = 0.001 respectively) than that of the control group and the heat and vibration application groups.ConclusionsIt was determined that local cold application for one minute to the area of peripheral intravenous catheterization increased venous dilation, shortened application time, and reduced pain.Trial registrationClinicalTrials.gov ID NCT06378424, retrospectively registered 20/04/2024.

Effect of Cold Application on Pain Relief during Intravenous Cannulation for Cancer Patients

Background: The cannulation of intravenous Analgesia is rarely experienced after this unpleasant procedure, which can also induce stress and worry. Objective: The purpose of the study was to ascertain how cold affected the degree of pain during intravenous cannulation. Methodology: A randomized controlled trial was carried out at the oncology department of AL-Al-Haboubi Teaching Hospital in Dhi-Qar from January 4, 2024, until February 3, 2024. After the sample was selected, 102 patients were divided into two groups in order to achieve the study's objective: 50 patients were assigned to the control group and 52 patients to the experimental group. The experimental group was given cold gel, and self-report data collection was used. A visual analogue scale of 10 cm was used to measure pain. Results: The experimental group's post-test results showed a low mean pain score (28.76+20.491), while the control group's data analysis results showed a high mean score (M+SD 76.54+20.427) and severe discomfort during cannulation insertion. The mean pain score during cannulation insertion varied significantly (p=.001) between the experimental and control groups following the use of cold treatment. Conclusions: According to the study's findings, the cool approach helped to lessen intravenous cannulation pain. Recommendations: The study advised patients to be chilled when receiving intravenous cannulation.

Injection Techniques to Reduce Adverse Effects of Subcutaneous Low-Molecular-Weight Heparin Among Patients With Cardiovascular Diseases: A Scoping Review.

To systematically review the existing literature and address the following research question: What are the most effective techniques used to minimise adverse effects resulting from subcutaneous injections of low-molecular-weight heparin among patients with cardiovascular diseases? A scoping review. A comprehensive search was conducted across multiple databases, including CINAHL, PubMed, EMBASE and the Cochrane Library, from 1 February 2014 to 31 January 2024. Participants were aged 18 years or older, diagnosed with venous thromboembolism or arterial thromboembolism and had prescribed subcutaneous injections of low-molecular-weight heparin. The collected data were analysed following the Joanna Briggs Institute approach, and it was organised and categorised based on the main objectives of the review. Twenty studies were eligible, including 1 best practice project, 7 randomised controlled trials and 9 quasi-experimental studies. The techniques under investigation encompassed various aspects, including the injection site, injection duration (e.g., 30 s vs. 10 s), injection method (e.g., needle insertion angle), duration of needle withdrawal after injection, pressure application time and cold pressure. Preliminary evidence suggests that techniques such as using the abdominal site and slower injection rates may help reduce adverse effects. However, the optimal parameters for injection duration, waiting time, pressure and cold application, including the duration of these applications, remain uncertain due to limitations in sample size and heterogeneity in interventions and outcome measures across the studies. Ensuring the accurate administration of low-molecular-weight heparin is of utmost importance as it plays a critical role in decreasing mortality rates and minimising substantial healthcare costs linked to complications arising from incorrect administration. The findings from the current review have significantly contributed to strengthening the evidence base in this field, providing more robust and reliable information. This review emphasises the significance of implementing standardised subcutaneous injection techniques for low-molecular-weight heparin in patients with cardiovascular disease in order to reduce complications and enhance patient outcomes. This study followed the applicable guidelines established by the PRISMA 2020 statement. The PRISMA checklist for systematic reviews was utilised for reporting purposes. There is no patient or public contribution to declare. OSF registries: osf.io/phk72.

Pain to cold food ingestion following root canal therapy: where is the source?

Two cases of pain evoked by cold food ingestion, following root canal therapy (RCT), are presented. The source of pain was detected when cold application to the vestibular, periapical area corresponding to the teeth involved evoked strong pain of about 30 sec durations. In the first case, the patient suffered from strong pain in the right mandibular area over the last 4 months. After successive RCT of 3 right mandibular teeth the spontaneous pain eased significantly, but strong pain evoked by cold food ingestion persisted. Cold application to the vestibular periapical area of teeth involved identified the source of pain, which was abolished by 80 mg/day of slow-release propranolol. In the second case, cold allodynia developed after RCT. The RCT was performed for prosthetic reasons with no prior pain. Pain could be duplicated by cold application to the vestibular area of the treated tooth. The patient preferred no treatment when the source of pain was explained. In both cases cold application did not produce any pain in other intra oral locations, including the contralateral vestibular area or the mid soft or hard palate. Pain mechanisms, neurovascular and neuropathic, which differ for each case are discussed.

Effectiveness of cold plasma application in oral wound healing process: A scoping review.

Cold atmospheric plasma (CAP) has shown an ability to promote wound healing by modulating biological processes without causing thermal damage. This scoping review aimed to evaluate the effectiveness of CAP application in the oral wound healing process. An electronic literature search was conducted using PubMed/Medline, Embase, Web of Science, Scopus, and grey literature (Google Scholar). The search included all articles published up to October 11, 2023. Only studies focusing on the different CAP types' effects on oral cavity wounds or cells were included in the review. This review analyzed 13 studies including seven cell culture studies, one animal study, and five human studies (three invivo and two exvivo). The findings from the reviewed articles suggest that CAP may have therapeutic potential. It can maintain cell viability and influence gene expression, accelerate wound healing, and modulate inflammation-related cytokines. DBD plasma exhibited time-sensitive effects on cellular behavior and microplasma irradiation positively impacted cell count, biochemical profiles, and cellular migration. The application of CAP has been shown to have a positive impact on the healing of oral wounds in cell culture, animal, and human studies.

Assessing the impact of cold plasma rotational dynamics on ginger's total phenolic content, antioxidant activity, surface structure and color using response surface methodology

This study investigated the efficacy of a rotational chamber in enhancing the effectiveness of cold plasma application to augment antioxidant activity and phenolic content in ginger (Zingiber officinale). To address the limitation of cold plasma (CP), which predominantly treats only the surface layers of samples, we implemented rotational techniques during the treatment. This methodology facilitates a more uniform treatment, ensuring that all layers of the samples are effectively exposed to plasma. We employed response surface methodology (RSM) to analyze the effects of three variables: power (10–90 W), treatment time (1–30 min), and pressure (0.4–0.9 mbar), along with a categorical variable for rotation. CP treatment (65 W, 0.7 mbar, 1 min with rotation) resulted in a significant increase in antioxidant activity compared to non-treated samples, determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric-reducing antioxidant power (FRAP), and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) ABTS assays, and total phenolic content reaching their highest values of 100.9 Trolox equivalent (TE) μmol⋅L−1, 8.23 Fe2+⋅g−1, 0.293 μmol⋅g−1, and 32.80 gallic acid equivalent (GAE)/g, respectively. There were no significant changes in color. Scanning Electron Microscopy (SEM) analysis revealed that the samples treated with CP exhibited a smoother surface, albeit with minimal damage to cell walls in our selected samples. Including a rotational feature as a unique upgrade to the cold plasma, the glow discharge device demonstrated positive enhancements and preservation of antioxidant activity and phenolic compounds.

Head and neck cooling enhance exercise tolerance in individuals with multiple sclerosis

BackgroundIndividuals with Multiple Sclerosis (MS) experience impairments in heat dissipation, compromising core temperature regulation during exercise. ObjectiveTo examine the efficacy of combined head-and-neck cooling as administered via a commercially available cooling cap and neck wrap in mitigating increases in core temperature during exercise. MethodsOn separate days, ten (7 females) adults (46.1 ± 11.6 years) with relapsing-remitting MS performed semi-recumbent cycling consisting of an incremental exercise bout to volitional fatigue in a temperate environment (23 °C, 50 % relative humidity) while undergoing head-and-neck cooling using a cooling cap and neck wrap maintained at 10 °C (COLD) or 24–26 °C (NEUTRAL). Prior to and following a 30-minute post-exercise recovery, functional capacity was assessed by a battery of tests consisting of a 2-minute walk test, Timed 25-Foot Walk test, sit-to-stand test, and Berg Balance Scale. Core (ingestible pill) and skin temperatures were recorded continuously. The level of fatigue was measured with questionnaires. ResultsThe duration of the incremental exercise test increased with the application of COLD (28.4 ± 5.1 min) versus NEUTRAL water (vs 20.8 ± 5.1 min) (p = 0.001) and was paralleled by a significant reduction in body temperatures (∼1 °C, p < 0.05). The distance covered during the 2-min walk test performed after the incremental exercise test increased with the COLD (176.5 ± 0.6 m), relative to the NEUTRAL condition (147.7 ± 43.5 m) (p = 0.01). Fatigue levels did not change between conditions. ConclusionWe show that head-and-neck cooling with cold water effectively enhances exercise tolerance and mitigates increases in core temperature during exercise in individuals with MS.

Enhancing Bone Healing Through Localized Cold Therapy in a Murine Femoral Fracture Model.

Fracture healing, a critical and complex biological process, often presents challenges in clinical practice with the current standards failing to fully address the medical needs for rapid and effective recovery. In this work, a localized cold therapy is investigated as an alternative approach to expedite bone healing. We hypothesized that optimized cold application can enhance bone healing within a fracture model by inducing hypoxia, leading to accelerated angiogenesis along with improved osteogenesis. A short, localized cold exposure is directly applied to the fracture site over a 4-week period in a mouse fracture model, aiming to assess its impact on bone formation through mechanisms of angiogenesis and osteogenesis. Our results revealed a significantly greater volume of new bone tissue and enhanced vascularity at the fracture site in the cold-treated group compared with controls. Calcified tissue histology analysis showed that the accelerated callus maturation and development of the vascular network following cold exposure were associated with an activity increase of alkaline phosphatase and transient receptor potential vanilloid 1. These biological changes were accompanied by a hypoxic environment induced during cold therapy. The study provides compelling evidence supporting the efficacy of intermittent cold therapy in accelerating fracture healing. These promising results highlight the need for further research in larger-scale studies and diverse fracture models, underlining the potential of cold therapy as a novel, noninvasive treatment strategy in orthopedic care.

Biochemical and Structural Characterization of a Novel Psychrophilic Laccase (Multicopper Oxidase) Discovered from Oenococcus oeni 229 (ENOLAB 4002).

Recently, prokaryotic laccases from lactic acid bacteria (LAB), which can degrade biogenic amines, were discovered. A laccase enzyme has been cloned from Oenococcus oeni, a very important LAB in winemaking, and it has been expressed in Escherichia coli. This enzyme has similar characteristics to those previously isolated from LAB as the ability to oxidize canonical substrates such as 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 2,6-dimethoxyphenol (2,6-DMP), and potassium ferrocyanide K4[Fe(CN6)], and non-conventional substrates as biogenic amines. However, it presents some distinctiveness, the most characteristic being its psychrophilic behaviour, not seen before among these enzymes. Psychrophilic enzymes capable of efficient catalysis at low temperatures are of great interest due to their potential applications in various biotechnological processes. In this study, we report the discovery and characterization of a new psychrophilic laccase, a multicopper oxidase (MCO), from the bacterium Oenococcus oeni. The psychrophilic laccase gene, designated as LcOe 229, was identified through the genomic analysis of O. oeni, a Gram-positive bacterium commonly found in wine fermentation. The gene was successfully cloned and heterologously expressed in Escherichia coli, and the recombinant enzyme was purified to homogeneity. Biochemical characterization of the psychrophilic laccase revealed its optimal activity at low temperatures, with a peak at 10 °C. To our knowledge, this is the lowest optimum temperature described so far for laccases. Furthermore, the psychrophilic laccase demonstrated remarkable stability and activity at low pH (optimum pH 2.5 for ABTS), suggesting its potential for diverse biotechnological applications. The kinetic properties of LcOe 229 were determined, revealing a high catalytic efficiency (kcat/Km) for several substrates at low temperatures. This exceptional cold adaptation of LcOe 229 indicates its potential as a biocatalyst in cold environments or applications requiring low-temperature processes. The crystal structure of the psychrophilic laccase was determined using X-ray crystallography demonstrating structural features similar to other LAB laccases, such as an extended N-terminal and an extended C-terminal end, with the latter containing a disulphide bond. Also, the structure shows two Met residues at the entrance of the T1Cu site, common in LAB laccases, which we suggest could be involved in substrate binding, thus expanding the substrate-binding pocket for laccases. A structural comparison of LcOe 229 with Antarctic laccases has not revealed specific features assigned to cold-active laccases versus mesophilic. Thus, further investigation of this psychrophilic laccase and its engineering could lead to enhanced cold-active enzymes with improved properties for future biotechnological applications. Overall, the discovery of this novel psychrophilic laccase from O. oeni expands our understanding of cold-adapted enzymes and presents new opportunities for their industrial applications in cold environments.

Experimental study on a novel split thermoelectric cooler of big temperature difference for combined cooling and heating supply

The improvement in maximum temperature difference is very important for thermoelectric cooler potential applications under severe and complex conditions. Currently, the maximum temperature difference of commercial single-stage thermoelectric modules represented is usually below 70 K and the energy efficiency is not high. In this paper, 12 kinds of split thermoelectric modules are developed according to different semiconductor and connector structures, and their performance is compared by experiments. The results show that the temperature difference of novel split thermoelectric cooler can exceed 200 K, which is more than 180 % higher than the currently commercial module (70 K), and it also has good performance under high ambient temperature. The new thermoelectric module can achieve the application of cold and hot ends energy on long-distance different occasions and has a module coefficient of performances of 2.68 and 1.29 under temperature differences of 57.43 K and 197.73 K, respectively. Meanwhile, a new asymmetric design method for independent control of hot and cold end temperatures is presented. It can achieve independent heat flux density design for cold and hot ends, and its performance can be further enhanced by regulating the temperature of connector.

Innovative dodecane-hexadecane/expanded graphite composite phase change material for sub-zero cold storage applications

Utilization of phase change materials (PCMs) for cold energy storage has garnered increasing attention. This study focuses on the development of a composite PCM by integrating a novel eutectic dodecane-hexadecane (DD-HD) PCM into expanded graphite (EG), to cater to the demands of sub-zero cold energy storage applications, such as cold chain logistics. The study identified the optimal mass ratio of DD-HD as 80:20. A series of DD-HD/EG composites were fabricated through a combination of high-speed emulsification and physical adsorption methods. The adsorption capacity of EG for the eutectic PCM mixture was evaluated by examining the impact of EG fraction on the leakage of the composite PCM, revealing that the optimum EG fraction is 10 wt%. The composite PCM displayed a sub-zero phase change temperature of -12.09 ℃, a high melting enthalpy of 178.75 kJ/kg, and a high thermal conductivity of 5.18 W/(m•K). The thermal conductivity of the composite was enhanced by 22.52 times compared to the base PCM. Thermogravimetric analysis indicated that the decomposition temperature of DD-HD/EG was significantly higher than that of the base PCM. The composite demonstrated outstanding thermal reliability, as evidenced by thermal cycle tests. With its impressive thermal characteristics, this composite shows great potential for various cold energy storage applications.

The effect of non-pharmacological methods on pain in patients undergoing open heart surgery: A systematic review and meta-analysis.

In this meta-analysis, we aimed to determine the effect of non-pharmacological methods on pain in patients undergoing open heart surgery. Scientific articles published between January 2002 and April 2022 were scanned in ScienceDirect, Scopus, PubMed, Web of Science, Google Scholar, Mendeley, Wiley Online Library databases. The keywords "open heart surgery," "cardiovascular surgery," "non-pharmacological," "complementary medicine," and "pain" were used in Turkish and English language. As a result of the search, 7,952 studies were identified and analyzed. Research data were obtained from 49 scientific articles. The total sample size of the studies included in the analysis was 3,097. The total effect size was found to be 3.070, with a 95% confidence interval of 2.522 at the lower limit and 3.736 at the upper limit. Non-pharmacological pain methods in open heart surgery included positive environmental experience, distraction, massage therapy, hand massage, foot massage, acupuncture therapy, lavender essential oil inhalation, cold application, music therapy, breathing and relaxation exercises, neurolinguistic programming, guided visualization, imagery, therapeutic touch, osteopathic treatment, and transcutaneous electrical nerve stimulation. The pain of patients who underwent open heart surgery with non-pharmacological methods combined with pharmacological methods was three times less than those without non-pharmacological methods. Based on these findings, non-pharmacological methods are recommended for use due to their ease of application, and low side effects.

Diagnosis and management of COVID toes in outpatients: a case report

BackgroundSince the beginning of the coronavirus disease 2019 pandemic, the most common skin lesions observed due to infection with the severe acute respiratory syndrome coronavirus 2 are pseudochilblains (or coronavirus disease toes). However, this pathology remains infrequent and difficult to diagnose, as no specific test exists.Case presentationTwo Caucasian women, 30 and 22 years old, presented to our General Medicine Unit with perniosis lesions on the feet during the first two waves of the coronavirus disease 2019 pandemic. They did not have respiratory or general symptoms of severe acute respiratory syndrome coronavirus 2 infection, the reverse transcription polymerase chain reaction on nasopharyngeal swabs was negative, and the serology was positive only in the first case. The clinical presentation differed for the two cases, as the second patient suffered from swelling and burning after cold application. The diagnosis was based on clinical presentation, temporality, exclusion of other differential diagnoses, and blood test results (positive serology in the first case and high level of CXCL13 and VEGF in the second), supported by current literature. Lesions resolved spontaneously in the first patient. The second case was hospitalized for pain management and received corticosteroid therapy with resolution of the symptoms.ConclusionThese two cases with different clinical presentations illustrate the diagnostic approach to coronavirus disease 2019, a challenging disease with diverse manifestations, including, in some cases, coronavirus disease toes. We present a literature review that illustrates the progression of scientific research. Skin lesions associated with coronavirus disease 2019 infection could be the expression of an important interferon type 1 response and should be considered in the differential diagnosis in a primary care setting.

Enhancement of rosehip bioactive compounds by cold plasma pretreatment and application of its extract as a functional ingredient in ketchup

The effect of cold plasma (CP) was investigated on rosehip characterization for 1,2.5, and 5 min. All of the samples that were treated with CP had higher amounts of total phenolic content (TPC), antioxidant activity, vitamin C, and lycopene compared to the control (P < 0.05). The extract obtained by rosehip pretreated for 1 min had the highest antioxidant activity as well as bioactive compounds (except anthocyanin) and was selected for application in ketchup. Utilizing the CP-treated rosehip extract (RE) in ketchup successfully enhanced TPC (by 1.44 times), flavonoids (by 1.31 times), antioxidant activity (by 1.21 times), carotenoids (by 1.74 times), lycopene (by 1.11 times), vitamin C (by 1.6 times), and anthocyanins (by 2.46 times) compared to the control (P < 0.05). Moreover, the phenolic profile demonstrated that the highest increase belonged to catechin. Therefore, the RE pretreated by CP has the potential to develop a functional ketchup with high bioactive substances.

A green binder for cold weather applications: enhancing mechanical performance of alkali-activated slag through modulus, alkali dosage, and Portland cement substitution

Below 5 °C, Portland cement (PC) experiences delayed hydration, slowing strength development, making it unsuitable for winter. Alkali-activated slag (AAS) emerges as a viable alternative with continuous hydration in low-temperature conditions. The effect of the activator nature on the performance of AAS cured at normal temperatures is well known, but further studies are required for low-temperature conditions. This study investigates the synergistic impact of activator modulus (1.2 and 1.5), alkali dosage (5, 7, and 9%), and PC substitution rates (0, 10, and 20%), on low-temperature cured AAS properties. Eighteen mixtures were prepared and cured at 2 °C. Compression and ultrasonic pulse velocity tests were conducted after 7, 28, and 90 days. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy analyses were performed to examine the microstructure of the samples. Elevating alkali dosage enhanced early age strength but resulted in a drop in 90-day strength. Simultaneous increases in modulus and PC substitution rate reduced strength due to shrinkage-induced crack formation. Optimal mixture design options included using 10% PC in the 1.2 modulus and omitting PC when the 1.5 modulus was selected. Despite low temperatures, the use of PC significantly accelerated the setting time. Altering modulus and alkali dosage caused a considerable change in the intensity of the peaks in the FTIR spectrum. The findings indicate that AAS shows promise when adjusting the mixture design for temperatures below 5 °C, which are unfavorable for the hydration of PC.
