Post-Cataract Surgery Fungal Endophthalmitis: 6-Year Experience in Management and Outcomes at a Tertiary Eye Care Center.

This study aimed to describe the functional and anatomical outcomes of post-cataract surgery fungal endophthalmitis at King Khaled Eye Specialist Hospital (KKESH). A retrospective analysis of clinical data from a single institution was performed. This study included 29 patients with post-cataract surgery endophthalmitis with suspected or confirmed fungal etiology who presented between January 1, 2017, and December 31, 2022. We evaluated demographics, clinical features, microbiological assessments, and treatment strategies. The effects of various treatments on outcomes were analyzed. The need for additional treatment and functional and anatomical outcomes was also investigated. The mean time from surgery to the onset of ocular symptoms was 52.1 (SD ± 59.9; range, 3-210) days, and the mean time from surgery to the first visit to KKESH was 81.4 (SD ± 103.5; range, 2-510) days. Low culture positivity was noted in four samples, with two revealing Aspergillus sp. and two revealing Cladosporium sp. Of the 29 patients, 6 underwent pars plana vitrectomy (PPV) and received intravitreal antimicrobial/antibiotic injections. Two of the six patients also underwent simultaneous intraocular lens removal. The average number of additional treatments, regardless of visual acuity, was lower in the PPV group than in the conservative group (0.5 [SD ± 1.1; range, 0-3] and 1.48 [SD ± 1.47; range, 0-6], respectively). In the PPV group, 50% (n=3) of the eyes achieved functional success and 83.3% (n=5) of the eyes achieved anatomical success. In contrast, in the conservative group, 43.5% (n=10) of the eyes achieved functional success and 69.6% (n=16) of the eyes achieved anatomical success. For post-cataract surgery fungal endophthalmitis, a high index of suspicion and prompt PPV with empirical administration of intravitreal antifungal agents are required to achieve a favorable prognosis.

Osteoporosis in Systemic Mastocytosis: A Scoping Review

Background: Mastocytosis (MS) is a rare disease that can involve various organs, including the bone. Given the incidence of the disease in the global population, MS poses a challenge for physicians, and early therapeutic intervention in the initial stages could significantly impact the quality of life of affected patients. Objective: The aim of this scoping review was to provide an overview of secondary osteoporosis in systemic mastocytosis (SM), focusing on the heterogeneity of its manifestations, the benefits of early diagnosis, and appropriate pharmacological treatment. Design: A technical expert panel (TEP) consisting of 8 physicians with expertise in metabolic bone diseases conducted the review following the PRISMA-ScR model. A strength of this study is that it provides various therapeutic approaches for patients with bone involvement in SM, although the limited available literature on the topic constituted a limitation. The TEP sought evidence regarding the following diagnostic and therapeutic modalities in the management of SM: “bisphosphonate therapy”, “zoledronic acid therapy”, “denosumab therapy”, “IFN-alpha therapy”, and “IFN-alpha therapy in combination with pamidronate”. Results: Clinical data showed a correlation between densitometric outcomes, serum tryptase levels, and mast cell infiltration in the bone marrow, between increased bone mineral density and the presence of osteosclerosis in cases of advanced SM, between the severity of osteoporosis and hypertryptasemia, and also provided results on the long-term effects of bisphosphonate therapy, the therapeutic efficacy of zoledronic acid administration, the positive effect of denosumab on the reduction of serum tryptase levels (even if is proved in a limited numbers of cases) and the prevention of new fractures, and the effect of IFN-alpha in more severe cases of SM, either alone or in combination with pamidronate. Conclusions: Studies have demonstrated the effectiveness of various treatments depending on the form of mastocytosis, whether indolent systemic or advanced systemic, in the prognosis of the disease. However, this role should be further investigated in additional clinical studies, considering the limited data on the use of these interventions.

Influence of Aloe Vera Gel and Safe Salts on Storage Quality of Minimally Processed Carrot

ABSTRACTThis experiment investigated the impact of aloe vera gel and safe salts on the physical quality and physicochemical properties of minimally processed carrots during storage, aiming to determine the most effective edible coating postharvest treatment. The experiment employed a Completely Randomized Design (CRD) with three replications. Results indicated significant (p ≤ 0.01) effects of various treatments on the physical quality and physicochemical properties of carrots compared to untreated ones. Freshly harvested carrots were subjected to different treatments, including a control (T1), 30% aloe vera gel (T2), 1% NaCl (T3), and 1.5% NaHCO3 (T4), combinations thereof, such as 30% aloe vera gel with 1% NaCl (T5) or 1.5% NaHCO3 (T6), and 1% NaCl with 1.5% NaHCO3 (T7), and a combination of 30% aloe vera gel with 1% NaCl and 1.5% NaHCO3 (T8). Among the treatments, the combination of 30% aloe vera gel and 1% NaCl (T5) exhibited the most promising results after nine days of storage, with the lowest weight loss (1.19%), highest firmness (3.80 N), total soluble solids (TSS) content (8.40%), titratable acidity (0.477%), ascorbic acid content (9.02 mg/100 g FW), anthocyanin content (28.84 μg/g FW), phenol content (4.278 mg/100 g FW), and total sugar content (13.32%). This treatment effectively protected carrots from undesirable color, texture, and flavor changes during storage. The utilization of natural‐source‐based edible coatings containing health‐promoting additives presents a viable strategy to enhance both the internal and external qualities of minimally processed carrots. Overall, the edible coating comprising 30% aloe vera gel and 1% NaCl emerges as a promising approach for preserving the quality of minimally processed carrots.

Using multi-modal spectroscopy technology and microscopic analysis to explore the regulation of ultra-high pressure heat-assisted treatment on the texture of ready-to-eat shrimp during storage

This study employed multi-modal spectroscopy technology and microscopic analysis to investigate the effects of various treatments on the texture of ready-to-eat (RTE) shrimps during storage. The results indicated that ultra-high pressure heat-assisted treatment (UHP-HAT) significantly improved the texture properties of RTE shrimps while simultaneously reducing the carbonyl and trichloroacetic acid-soluble properties associated with protein oxidative degradation. Furthermore, UHP-HAT resulted in a denser and more ordered protein structure, which contributed to an increased content of bound and immobile water. A partial least squares regression model for texture prediction was developed using data obtained from hyperspectral imaging, demonstrating a strong correlation between spectral information and texture parameters. Additionally, infrared imaging was utilized to elucidate the distribution of functional groups (OH, CO, CH) and carbonyl compounds within the proteins. Overall, the findings suggested that UHP-HAT could effectively delay the deterioration of texture by mitigating protein degradation.

Development of a New Swine Model Resembling Human Empty Nose Syndrome.

Background and Objectives: Empty nose syndrome (ENS) is a debilitating condition that often results from traumatic or iatrogenic causes, such as nasal surgery. There are various conservative and surgical treatments for ENS, but their effectiveness remains uncertain. Therefore, the development of animal models that accurately mimic human ENS is essential for advancing effective treatment strategies. Materials and Methods: To investigate ENS development, turbinoplasty was performed in the nasal cavity of swine, entailing partial removal of the ventral turbinate using turbinectomy scissors followed by electrocauterization. After 56 days, samples were obtained for histological and morphological analyses. Results: A significant reduction in the volume of the ventral turbinate in the ENS model led to an expansion of the nasal cavity. Histological analysis revealed mucosal epithelial changes similar to those observed in ENS patients, including squamous cell metaplasia, goblet cell metaplasia, submucosal fibrosis, and glandular atrophy. Biomarkers related to these histopathological features were identified, and signals potentially contributing to squamous cell metaplasia were elucidated. Conclusions: The swine ENS model is anticipated to be instrumental in unraveling the pathogenesis of ENS and may also be useful for evaluating the effectiveness of various treatments for ENS.

Effects of soil amendments and coverings on the kenaf yield and soil physicochemical properties in saline-alkali land

In order to investigate the effects of various treatments on the growth of kenaf in saline soil, this study employed a comprehensive experimental design incorporating a dual approach of soil amendment and mulching techniques. Soil treatment of saline and alkaline land, as well as biological material mulching treatment after sowing kenaf, were conducted. The growth dynamics of kenaf were assessed before the mid-term investigation, and the harvest period was examined. Soil physicochemical properties were measured and analysed at different periods. The results show that in the analysis of red sesame yield traits, the differences mainly appeared between soil treatments. There is no significant difference between the different mulching treatments within each soil treatment. In the mid-term study, significant differences were observed in kenaf plant height. Plant height was the most affected by soil conditioners, while other yield traits did not show significant variations. During harvest, only stem thickness and dry weight of a single plant did not show significant differences, whereas other yield traits did. The application of soil conditioners resulted in a 58.15% increase in dry hull yield compared to organic fertilizers and a 22.66% increase compared to regular fertilizers. Soil conditioners also led to higher levels of effective phosphorus, quick-acting potassium, organic matter, and total nitrogen throughout the kenaf growth period compared to organic and regular fertilizers. This is beneficial for enhancing soil quality and reducing soil alkalinity. Combined with the results of kenaf yield and soil physical and chemical properties analysis, it has been proven that the application of soil conditioner has the best effect, followed by the application of compound fertilizer, with organic fertilizer treatment being the least effective.

Effect of Various Treatment and Drying Methods of Blood Meal Additive on Fresh State Properties of Grouting Materials

Functional, nutritional, and sensorial evaluation of sorghum-based beverages produced by single- and two-stage acid, α-amylase enzyme, and germination treatments.

Nowadays, the consumption of functional foods, such as plant-based beverages, is increasing due to their health-promoting properties. The low extraction yield of nutritional and functional components is considered a major challenge during the production of sorghum-based beverages (SBB), as well as their sensorial properties. This investigation studied the effects of various treatments (acidic using phosphoric acid, enzymatic using α-amylase, germination, germination-acidic, germination-enzymatic, and acidic-enzymatic) on the functional, nutritional, and sensorial properties of SBB. The two-stage acidic-enzymatic treatment demonstrated the highest extraction yield, dry matter, ash, carbohydrates, and reducing sugar contents, as well as the lowest starch content (p < .05). Furthermore, the highest protein content (0.98%) was achieved by the germination treatments of sorghum grains. While the highest fat content was achieved by the acidic treatment (1.38%), the germination-acidic treatment exhibited the highest energy value (26.02 kcal/100 mL). Moreover, the total phenolic content of the acidic-enzymatic treatment (44.56 mg GAE/L) was significantly higher than that of other treatments. However, all treatments demonstrated lower antioxidant properties compared to the control treatment (142.85 mg BHT eq./L). Furthermore, the sensory evaluation of the germination and germination-enzymatic treatments showed acceptable scores (≥7) for consumers. In conclusion, the results indicated that the two-stage treatments of sorghum, especially the acidic-enzymatic treatment, were more effective than single treatments for the extraction of functional and nutritional components during the production of SBB.

Enhancing maize growth and resilience to environmental stress with biochar, gibberellic acid and rhizobacteria.

Zea mays (maize) is a globally significant cereal crop with diverse applications in food, feed, and industrial products. However, maize cultivation is often challenged by environmental stressors such as heavy metal toxicity and drought stress (DS). Heavy metals like cadmium (Cd) and lead (Pb) can accumulate in soil through industrial activities and improper waste disposal, posing significant threats to plant growth and development. Drought stress further exacerbates these challenges by limiting water availability and affecting physiological processes in plants. This study explores the impact of Cd and Pb toxicity, as well as DS, on maize growth and development, and investigates the potential mitigating effects of various treatments, including gibberellic acid (GA3), biochar (BC), rhizobacteria (RB), and their combinations. The experiment involved maize plants subjected to different stress conditions: cadmium (Cd) at concentrations of 0, 6, and 12 ppm, lead (Pb) at 0 and 400 ppm, and drought stress (DS). Treatments included the application of 10 ppm GA3, 0.75% BC, a combined treatment of 10 ppm GA3 and 0.75% BC, rhizobacteria (RB), and a combined treatment of 0.5% BC and RB. The study measured germination rates, shoot and root lengths, and biochemical parameters such as shoot and root protein, phenolics, and chlorophyll contents under these conditions. In the absence of Cd stress (0 Cd), the application of 10 ppm GA3 and 0.75% BC significantly enhanced germination rates by 72% and 76%, respectively, compared to the control, with the combined treatment exhibiting the highest enhancement of 86%. Under Cd stress (6 ppm Cd), GA3 and BC individually improved germination by 54% and 57%, respectively, with the combined treatment showing the largest increase of 63%. Drought stress influenced germination, with notable improvements observed with the application of 0.5% BC (50% increase) and RB (49% increase). Similar trends were observed in shoot and root lengths, where the combined treatment of GA3 and BC resulted in the most significant improvements. The treatments positively influenced shoot and root protein, phenolics, and chlorophyll contents, particularly under stress conditions. These findings highlight the potential of combined treatments, such as the application of GA3 and BC or BC with RB, in alleviating the adverse effects of heavy metals (Cd and Pb) and drought stress in maize cultivation. The combined treatments not only improved germination rates but also significantly enhanced shoot and root growth, as well as important biochemical parameters under stress conditions. This suggests that GA3 and BC, alone or in combination with RB, can play a crucial role in enhancing maize resilience to environmental stressors. The study highlights the importance of exploring sustainable agricultural practices to mitigate the impacts of heavy metal toxicity and drought stress. Future research should focus on long-term field trials to validate these findings and further investigate the mechanistic pathways involved in stress mitigation by these amendments, as well as their economic feasibility and environmental impact on a larger scale to ensure their practical applicability in real-world agricultural settings.

Effectiveness of Different Treatment Modalities in Initial and Chronic Phases of Thyroid Eye Disease: A Systematic Review With Meta-analysis.

Thyroid eye disease (TED), a common extrathyroidal manifestation of Graves disease, poses significant management challenges due to potential disfigurement, visual impairment, and decreased quality of life. Uncertainties remain about the optimal treatment approach, especially regarding TED duration and its impact on outcomes. This meta-analysis evaluates the effects of various treatments on inflammatory markers and severity endpoints in TED, stratified by disease duration, distinguishing between treatments initiated within the first 6 months (initial phase) and those initiated thereafter (subacute/chronic phase). Following PRISMA guidelines, a systematic search of multiple electronic databases yielded 26 studies meeting predefined inclusion criteria. Methodological quality was assessed, and data were meticulously extracted and analyzed. In the initial phase, treatments like corticosteroids and teprotumumab showed significant improvements in clinical activity score, proptosis, and diplopia. In the subacute/chronic phase, the efficacy of methylprednisolone and teprotumumab is reduced. A "critical window" effect was observed, with treatments showing diminished efficacy after 6 months of TED duration. This meta-analysis highlights the importance of tailoring treatment strategies based on TED duration, emphasizing early interventions to maximize benefits. The findings guide clinicians in selecting optimal treatments and underscore the need for further research to refine evidence-based approaches, ultimately enhancing patient outcomes and quality of life.

Assessment of prevalence of sexual dysfunction in patients having lower urinary tract symptoms with benign prostatic hyperplasia and effect of various treatment modalities on sexual function.

Sexual dysfunction affects a couple's relationship and quality of life of the patient and the partner irrespective of age. In Lower urinary tract symptoms (LUTS) with benign prostatic hyperplasia (BPH), sexual dysfunction is highly prevalent. This study aims to evaluate prevalence of sexual dysfunction in patients having LUTS with BPH and effect of various treatment on it. The study is hospital based prospective cross-sectional study. Total 106 patients were included in this study. Fifty-six patients underwent medical treatment and 50 patients underwent transurethral resection of prostate (TURP) according to lower urinary tract symptom score along with grades of prostate. We measured prevalence of lower urinary tract symptoms, erectile dysfunction (ED), ejaculatory dysfunction (EJD).We compared the pre and post treatment ED, EJD scores in both medical and TURP group. In our study, 11 (10.4%) patients had very mild ED, 12 (11.3%) had mild ED, 54 (50.9%) had moderate ED and 23 (21.7%) had severe ED. In our study, 11 (10.4%) patients had very mild EJD, 7 (6.6%) had mild EJD, 28 (26.4%) had moderate EJD and 2 (1.9%) had severe EJD. In medical group, ED pre-treatment versus ED post treatment was statistically significant (p = 0.0046), treatment of LUTS improves ED. EJD pre-treatment versus EJD post treatment was not statistically significant (p = 0.8368), treatment of LUTS associated with deterioration of EJD. In TURP group association of ED pre-treatment versus ED post treatment was statistically significant (p = 0.0319). Post TURP patients shows improvement in ED Association of EJD pre-treatment versus EJD post-treatment was statistically significant (p = 0.03000). Post TURP EJD deteriorate. We concluded that the severity of sexual dysfunction correlates with severity of LUTS. Ejaculatory function deteriorates after treatment of TURP compared to medical.

Antidepressant activity of tricin-7-O-glucoside and anxiolytic-like effect of harmane from Passiflora coriacea Juss. On mice

Ethnopharmacological relevancePassiflora coriacea Juss., a medicinal plant in the family Passifloraceae, is widely used to treat anxiety and depression in Mexican folk medicine. However, its chemical profile and biological activity have not been characterized. Aim of the studyThe aim of the study was to determine the antidepressant activity, anxiolytic effect, and chemical profile of Passiflora coriacea. Materials and methodsAn organic fraction (PcEA) from a hydroalcoholic extract of the aerial parts of P. coriacea was obtained, followed by a chemical analysis and separation, yielding six fractions (PcEA, T1, T2, T1.1, T2.1, and T2.2). Male ICR mice were used to determine the antidepressant activity of selected treatments (PcEA, T1, T2, and T1.1) based on a forced swim test (FST). The anxiolytic-like effects of various treatments (PcEA, T1, T2, T2.1, and T2.2) were determined using the elevated plus maze (EPM) test. ResultsThe organic fraction of P. coriacea decreased anxiety-like behaviors in mice and increased the time of mobility in the FST. After chemical separation, two compounds were isolated from the species with antidepressant activity and anxiolytic-like effects, T1.1 (tricin 7-O-glucoside) and T2.2 (harmane), respectively. ConclusionsCompounds isolated from P. coriacea exerted anxiolytic and antidepressant effects in mice based on the EPM and FST. The flavonoid tricin-7-O-glucoside and the alkaloid harmane contributed to these biological activities.

Robust inference for causal mediation analysis of recurrent event data.

Recurrent events, including cardiovascular events, are commonly observed in biomedical studies. Understanding the effects of various treatments on recurrent events and investigating the underlying mediation mechanisms by which treatments may reduce the frequency of recurrent events are crucial tasks for researchers. Although causal inference methods for recurrent event data have been proposed, they cannot be used to assess mediation. This study proposed a novel methodology of causal mediation analysis that accommodates recurrent outcomes of interest in a given individual. A formal definition of causal estimands (direct and indirect effects) within a counterfactual framework is given, and empirical expressions for these effects are identified. To estimate these effects, a semiparametric estimator with triple robustness against model misspecification was developed. The proposed methodology was demonstrated in a real-world application. The method was applied to measure the effects of two diabetes drugs on the recurrence of cardiovascular disease and to examine the mediating role of kidney function in this process.

Systematic evaluation of the efficacy of treatments for cesarean scar pregnancy

Study objectiveCesarean scar pregnancy (CSP) is a type of ectopic pregnancy associated with severe complications, including significant hemorrhage, the potential need for hysterectomy, and life-threatening risks. Currently, two classification methods exist for CSP: Vial (type Ia and IIa) and Chinese Expert’s Consensus (type Ib, type IIb, and type IIIb). However, these methods have limitations in guiding the selection of appropriate treatment plans for CSP. The purpose of this study was to systematically evaluate the effectiveness of various treatments for CSP within our clinic.MethodOur study included 906 patients with CSP from January 2013 to December 2018. The chi-squared test and logistic analysis were used to compare the clinical characteristics. The median and interquartile range (IQR) was calculated. We also analyzed whether preoperative application of methotrexate (MTX) could improve surgical outcomes and the relevant characteristics of misdiagnosed CSP patients.ResultsThere was a significant difference in gestational age, gestational sac diameter, gestational sac width, gestational sac area, remnant myometrial thickness, vaginal bleeding and preoperative hemoglobin levels (p < 0.001) but not in the incidence of residual tissue (p = 0.053). The other factors (intraoperative blood loss, hemoglobin decline, first hemoglobin after operation, total hospital stay, hospital stay after operation, transfusion and duration of catheter drain) were significantly different (p < 0.001). For type Ia and type Ib CSP, 39.3% and 40.2% of patients were treated with dilatation and curettage (D&E) under ultrasound, respectively. For type IIa and type IIIb CSP, 29.9% and 62.7% of patients were treated with laparotomy, respectively. There were no differences in surgical methods, residual tissue and reoperation between the MTX and non-MTX groups (p = 0.20), but liver damage, hospital stay and pain perception were more remarkable in the MTX group. It is noteworthy that 14% of the patients were misdiagnosed with an intrauterine pregnancy. The incidence of misdiagnosis in type IIa CSP patients was higher than that in type Ia CSP patients (p < 0.001).ConclusionFor type I CSP patients, D&E under ultrasound or D&E under hysteroscopy should be recommended. For type IIIb CSP patients, operative resection should be used. It is currently difficult to choose the appropriate treatment methods for type IIa or type IIb CSP patients.

Micromassage Compression Leggings Associated with Physical Exercise: Pilot Study and Example of Evaluation of the Clinical and Instrumental Effectiveness of Conservative Treatment in Lipedema.

We evaluated the effect of compression leggings with micromassage in association with physical activity on women with lipedema, not previously treated and without recent changes in body weight. The treatment resulted in an improvement in all subjective parameters, in spontaneous and evoked pain, in the volume of the limbs, in the absence of significant changes in body weight, and regardless of the duration of use, age, years of illness, the clinical stage, and body mass index (BMI). Evoked pain did not improve in areas affected by untreated lipedema; foot circumferences did not increase. We found a significant reduction in the thickness of subcutaneous adipose tissue (SAT) and skin evaluated in multiple points of the lower limb. Micromassage compression leggings are proposed as an integral part of conservative treatment. A method is proposed for the clinical evaluation of evoked pain, called the Progressive Pain Check (PPC), which allows for the calculation of a numerical score called the Ricolfi-Patton Score (RPS) and for the ultrasound evaluation of tissues. The method is simple and repeatable and allows for completion of the clinical evaluation of the patient at diagnosis and for an evaluation of the effects of various treatments, even applied to just one side of the body.

Real-world severe COVID-19 outcomes associated with use of antivirals and neutralising monoclonal antibodies in Scotland

We sought to investigate the incidence of severe COVID-19 outcomes after treatment with antivirals and neutralising monoclonal antibodies, and estimate the comparative effectiveness of treatments in community-based individuals. We conducted a retrospective cohort study investigating clinical outcomes of hospitalisation, intensive care unit admission and death, in those treated with antivirals and monoclonal antibodies for COVID-19 in Scotland between December 2021 and September 2022. We compared the effect of various treatments on the risk of severe COVID-19 outcomes, stratified by most prevalent sub-lineage at that time, and controlling for comorbidities and other patient characteristics. We identified 14,365 individuals treated for COVID-19 during our study period, some of whom were treated for multiple infections. The incidence of severe COVID-19 outcomes (inpatient admission or death) in community-treated patients (81% of all treatment episodes) was 1.2% (n = 137/11894, 95% CI 1.0-1.4), compared to 32.8% in those treated in hospital for acute COVID-19 (re-admissions or death; n = 40/122, 95% CI 25.1-41.5). For community-treated patients, there was a lower risk of severe outcomes (inpatient admission or death) in younger patients, and in those who had received three or more COVID-19 vaccinations. During the period in which BA.2 was the most prevalent sub-lineage in the UK, sotrovimab was associated with a reduced treatment effect compared to nirmaltrelvir + ritonavir. However, since BA.5 has been the most prevalent sub-lineage in the UK, both sotrovimab and nirmaltrelvir + ritonavir were associated with similarly lower incidence of severe outcomes than molnupiravir. Around 1% of those treated for COVID-19 with antivirals or neutralising monoclonal antibodies required hospital admission. During the period in which BA.5 was the prevalent sub-lineages in the UK, molnupiravir was associated with the highest incidence of severe outcomes in community-treated patients.

The impact of hyperkalemia on ICU admission and mortality: a retrospective study of Chinese emergency department data

ObjectiveThis study assesses the influence of hyperkalemia on both disease severity and the risk of mortality among patients admitted to the emergency room.MethodsThis retrospective observational study utilized data from the Chinese Emergency Triage Assessment and Treatment database (CETAT, version 2.0), which was designed to evaluate and optimize management strategies for emergency room (ER) patients. Patients were systematically categorized based on serum potassium levels. Relationships between serum potassium levels, risk of mortality, and the severity of illness were then analyzed using multifactorial logistic regression and through Receiver Operating Characteristic (ROC) analysis. The effectiveness of various treatments at lowering potassium levels was also investigated.Results12,799 emergency patients were enrolled, of whom 20.1% (n = 2,577) were hypokalemic and 2.98% (n = 381) were hyperkalemic. Among hyperkalemic patients, the leading reasons for visiting the ER were altered consciousness 23.88% (n = 91), cardiovascular symptoms 22.31% (n = 85), and gastrointestinal symptoms 20.47% (n = 78). Comparative analysis with patients exhibiting normal potassium levels revealed hyperkalemia as an independent factor associated with mortality in the ER. Mortality risk appears to positively correlate with increasing potassium levels, reaching peaks when blood potassium levels ranged between 6.5 and 7.0. Hyperkalemia emerged as a strong predictor of death in the ER, with an Area Under the Curve (AUC) of 0.89. The most frequently prescribed treatment for hyperkalemia patients was diuretics (57.32%, n = 188), followed by intravenous sodium bicarbonate (50.91%, n = 167), IV calcium (37.2%, n = 122), insulin combined with high glucose (27.74%, n = 91), and Continuous Renal Replacement Therapy (CRRT) for 19.82% (n = 65). Among these, CRRT appeared to be the most efficacious at reducing potassium levels. Diuretics appeared relatively ineffective, while high-glucose insulin, sodium bicarbonate, and calcium preparations having no significant effect on the rate of potassium decline.ConclusionHyperkalemia is common in emergency situations, especially among patients with altered consciousness. There is a strong positive correlation between the severity of hyperkalemia and mortality risk. CRRT appears to be the most effective potassium reducting strategy, while the use of diuretics should be approached with caution.

Quantitative Analysis of Stress-Stretch Curves in Canine Lumbar Vertebrae Using Modified Logistic Functions.

The mechanical characteristics of bone are crucial for comprehending its functionality and response to different load conditions, which are essential for advancing medical treatments, implants, and prosthetics. By employing mathematical modeling to analyze the mechanical properties of bone, we can assess stress and deformation under both normal and abnormal conditions. This analysis offers valuable perspectives on potential fracture risks, the effects of diseases, and the effectiveness of various treatments. Therefore, researchers are attempting to find an adequate mathematical description of the mechanical properties of bone. Experimental stress-stretch external loading curves were obtained through investigations of canine vertebrae. The obtained experimental curves were fitted using the SciPy Python library with a slightly modified logistic function (logistic function plus additional const). The resulting coefficient of determination R2 (R squared) for most curves was near 0.999, indicating that an appropriate fitting function was selected for the description of the experimental stress-stretch curves. The stress-stretch behavior of canine vertebrae can be described using a logistic function modified by adding additional parameters for the most accurate fitting results.

A compact setup for behavioral studies measuring limb acceleration

Behavioral studies contribute largely to a broader understanding of human brain mechanisms and the process of learning and memory. An established method to quantify motor learning is the analysis of thumb activity. In combination with brain stimulation, the effect of various treatments on neural plasticity and motor learning can be assessed. So far, the setups for thumb abduction measurements employed consist of bulky amplifiers and digital-to-analog devices to record the data. We developed a compact hardware setup to measure acceleration data which can be integrated into a wearable, including a sensor board and a microcontroller board which can be connected to a PC via USB. Additionally, we provide two software packages including graphical user interfaces, one to communicate with the hardware and one to evaluate and process the data. This work demonstrates the construction and application of our setup at the example of thumb acceleration measurement with a custom made glove and its use for research. Using integrated circuits, the size of the measurement devices is reduced to this wearable. It is simple to construct and can be operated easily by non-technical staff.

Understanding the mechanism of acupuncture in acute cerebral infraction through a proteomic analysis: protocol for a prospective randomized controlled trial.

Acute cerebral infarction (ACI), being the predominant form of stroke, presents challenges in terms of the limited effectiveness of various treatments in improving the neurological function. Although acupuncture shows promise in addressing ACI, the availability of high-quality evidence regarding its efficacy, safety, and underlying mechanism remains insufficient. In this study, we design a multicenter, prospective, single-blind, randomized controlled trial with the aim of evaluating the efficacy and safety of acupuncture for ACI, making an attempt to unveil the molecular mechanisms by proteomic. A total of 132 patients involving four hospitals will be randomized at a 1:1:1 ratio in the acupuncture group, control group, and sham acupuncture group. All the patients will receive basic treatment, and the patients in the acupuncture and sham acupuncture groups will also receive either acupuncture or sham acupuncture treatment, respectively, at six sessions each week for a 2 weeks period, followed by 3 months of follow-up. The primary outcome will be the change in the National Institute of Health Stroke Scale (NIHSS) scores after treatment. The secondary outcomes will include the Fugl-Meyer Assessment (FMA) scale scores and the Barthel Index (BI). Adverse events that occur during the trial will be documented. To discover differentially expressed proteins (DEPs) and their roles between the ACI subjects and healthy controls, we will also perform 4D-DIA quantitative proteomics analysis, and the DEPs will be confirmed by enzyme-linked immunosorbent assay (ELISA). This study was approved by the institutional review board of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine (TYLL2023043). Written informed consent from patients is required. This trial is registered in the Chinese Clinical Trial Registry (ChiCTR2300079204). Trial results will be published in a peer-reviewed academic journal. The results of this study will determine the preliminary efficacy and safety of acupuncture in ACI patients and whether the mechanism of this form of non-pharmacologic stimulation is mediated by a novel therapeutic target for neurorehabilitation through our proteomic analysis. https://www.chictr.org.cn, identifier ChiCTR2300079204.
