The major agents leading to the development of varicose veins include: Hereditary, prolonged standing, Increasing age, Heavy lifting, Prior superficial or deep vein clots, Female gender and Multiple pregnancies. In this manuscript, we report a case of inguinal varicose vein in connection with femoral vein, resulted from direct intravenous injection of drug. The diagnosis was made based on Doppler sonography.

Drug Use and Abuse among Orthopedic Ward Patients—A Revolving Cycle of Menace in Atbuth, Bauchi

Background: The use of drugs for purposes other than those for which they are meant to be used or in excess amounts. Psychoactive drugs are some of the drugs more commonly abused, also, antibiotics and other medications too can be misused. Drug abuse and misuse can lead to serious social, medical and emotional harm to the patients, and antibiotic resistance that makes treatment harder are also likely complications. Method: Patients in both male and female wards of the Orthoepaedics Department of ATBUTH, Bauchi were interviewed using a structured questionnaire and their responses were recorded and data were analyzed using the SPSS version 29. Results: A total of 112 patients were interviewed, 76 males and 36 females. Thirty-two (28.6%) patients had taken various kinds of unprescribed medications while on admission: 9 patients had taken unprescribed tramadol, 4 patients had taken codeine, 6 Ampiclox, 5 flagyl and about 8 patients had taken different kinds of traditional medications while on admission. Among the 32 patients, 23 (72%) are aged less than 30 years, 5 (16%) are aged between 30 and 50 years and 4 (12%) are aged above 50 years. Sixteen (50%) had such medications brought to them by relatives or friends, 10 (30%) were given by other patients on admission, 5 (15%) brought or bought the drugs by themselves while 1 (5%) were given by a non-clinical staff of the hospital. Conclusion: Drug misuse and abuse is a very serious, deleterious practice with destructive consequences in its wake, such consequences as drug dependency with all its antecedent effects, antibiotic resistance and difficulties in controlling/managing infections are but a few. So, it’s very important to both educate patients about these terrible practices and cope with the spread of them in our wards and hospitals.

Application of Patient Simulators Combined with Internet plus Scenario Simulation Teaching Models on Intravenous Infusion Nursing Education in China

Objective: To explore the effectiveness of applying patient simulators combined with Internet Plus scenario simulation teaching models on intravenous (IV) infusion nursing education, and to provide scientific evidence for the implementation of advanced teaching models in future nursing education. Methods: Enrolled 60 nurses who took the IV infusion therapy training program in our hospital from January 2022 to December 2023 for research. 30 nurses who were trained in traditional teaching models from January to December 2022 were selected as the control group, and 30 nurses who were trained with simulation-based teaching models with methods including simulated patients, internet, online meetings which can be replayed and scenario simulation, etc. from January to December 2023 were selected as the experimental group. Evaluated the learning outcomes based on the Competency Inventory for Nursing Students (CINS), Problem-Solving Inventory (PSI), comprehensive learning ability, scientific research ability, and proficiency in the theoretical knowledge and practical skills of IV infusion therapy. Nursing quality, the incidence of IV infusion therapy complications and nurse satisfaction with different teaching models were also measured. Results: The scientific research ability, PSI scores, CINS scores, and comprehensive learning ability of the experimental group were better than those of the control group (P 0.05), and their assessment results of practical skills, nursing quality of IV infusion therapy during training, and satisfaction with teaching models were all better than those of the control group with statistical significance (P < 0.05). The incidence of IV infusion therapy complications in the experimental group was lower than that in the control group, indicating statistical significance (P < 0.05). Conclusions: Teaching models based on patient simulators combined with Internet Plus scenario simulation enable nursing students to learn more directly and practice at any time and in any place, and can improve their proficiency in IV infusion theoretical knowledge and skills (e.g. PICC catheterization), core competencies, problem-solving ability, comprehensive learning ability, scientific research ability and the ability to deal with complicated cases. Also, it helps provide high-quality nursing education, improve the nursing quality of IV therapy, reduce the incidence of related complications, and ensure the safety of patients with IV therapy.

Pain and immune function in patients undergoing gastric cancer surgery following stellate ganglion block with total intravenous anesthesia

BACKGROUND Stellate ganglion block is a commonly used sympathetic nerve block technique that restores the balance of the sympathetic and vagal nervous systems of the body and inhibits sympathetic nerve activity.AIM To analyze the effect of a stellate ganglion block combined with total diploma intravenous anesthesia on postoperative pain and immune function in patients undergoing laparoscopic radical gastric cancer(GC)surgery to provide a refe-rence basis for the formulation of anesthesia protocols for radical GC surgery.METHODS This study included 112 patients who underwent laparoscopic radical surgery for GC between January 2022 and March 2024.There was no restriction on sex.The patient grouping method used was a digital random table method,and the num-ber of cases in each group was 56.The control group was administered total intravenous anesthesia,and the observation group compounded the stellate gan-glion block according to the total intravenous anesthesia protocol.Postoperative hemodynamics,pain levels,and immune indices were compared between the groups.RESULTS The heart rate and mean arterial pressure in the observation group after in-tubation were lower than those in the control group(P<0.05).Pain levels were compared between the two groups at 2 hours,12 hours,24 hours,and 48 hours after surgery(P>0.05).The number of CD3+,CD4+,and CD4+/CD8+cells at the end of surgery was higher in the observation group than in the control group,and the number of CD8+cells was lower in the observation group than in the control group(P<0.05).There were no significant differences between the two groups in terms of propofol dosage,awakening time,extubation time,or postoperative adverse reactions(P>0.05).CONCLUSION The application of a stellate ganglion block combined with total intravenous anesthesia had no significant effect on postoperative pain levels in patients undergoing laparoscopic radical GC surgery.However,it can safely reduce the effect of surgery on the immune function of patients and is worth applying in clinical practice.

The Aesthetic Characteristics of Emotional Abuse in The Japanese Movie“0.5mm”

The Japanese movie“0.5mm”connects the life clips between the nursing-care helper Sawa and several old people in the form of a road movie,highlighting many thought-provoking social problems,and revealing how the elements of emotional abuse hidden between the old people and their relatives and friends affect people’s dignity and decency,and at the same time trying to offset the persecution from the emotional abuse with the warm kindness between the elderly and the care workers.The film’s implicit description of emotional abuse and explicit display of good deeds are blended in the quiet and mysterious narrative character,achieving the effect of synchronizing the artistic narrative rhythm with the flow of life,reflecting the unique aesthetic characteristics of Japanese films.

Early Application Study of Intravenous Pain Pump Combined with Parecoxib Injection in Relieving Pain in Patients after Thoracoscopy

Objective: To explore the clinical effectiveness of combined use of intravenous pain pump with Parecoxib injection in alleviating pain in patients during the early postoperative period after thoracoscopic surgery. Methods: Eighty patients who underwent thoracoscopic surgery in a tertiary hospital were selected as the study subjects and randomly divided into two groups, with 40 patients in each group. The control group received routine postoperative treatment with intravenous pain pump, while the experimental group received Parecoxib in addition to the standard postoperative pain pump treatment. Visual Analog Scale (VAS) pain scores were used to evaluate postoperative pain relief in both groups, along with adverse reactions, postoperative complications, and patient satisfaction with pain relief. Results: Patients who received Parecoxib injection in addition to the routine use of intravenous pain pump had VAS pain scores lower than 3 points at 6 h, 12 h, 24 h, and 36 h postoperatively compared to those in the control group. The incidence of postoperative lung collapse, pleural effusion, and pulmonary infections was also significantly lower in the experimental group. The differences between the two groups were statistically significant (P Conclusion: Early combined use of Parecoxib injection in the early postoperative period after thoracoscopic surgery has shown good clinical efficacy. It can reduce the level of pain in patients, promote effective coughing and expectoration, facilitate early mobilization of patients, improve patient compliance, reduce complications, shorten hospital stay, and expedite patient recovery. Therefore, it is worth promoting the widespread clinical application of Parecoxib injection in this setting.

Effectiveness and safety of rocuronium or nitroglycerin plus ropivacaine on pain during intravenous regional anesthesia:A double-blind randomized controlled trial

Objective:To compare the effects of adding rocuronium and nitroglycerin to ropivacaine in intravenous regional anesthesia(IVRA)on pain and hemodynamic parameters.Methods:This randomized controlled trial was done in 2023.Participants were 177 candidates for forearm operation surgery under IVRA selected from Valiasr Hospital,Arak,Iran.They were allocated by block randomization to three different groups,namely nitroglycerin group,rocuronium group and control group.Hemodynamic parameters were recorded before tourniquet application up to postoperative recovery time.Sensory block and motor block onset and duration and pain were also evaluated.The data analysis was carried out by IMB SPSS software 20.0.Results:177 Eligible patients were included in study,with 59 in each group.Time to sensory and motor block onset in the nitroglycerin group was significantly less than the other groups and the time of motor block in the rocuronium group was statistically higher than the control and the nitroglycerin groups(P<0.001).Seven participants in the nitroglycerin group experienced headache and three from the rocuronium group experienced dizziness.The side effects occurrence in the nitroglycerin group was more prevalent than in the control and rocuronium groups(P=0.009).Conclusions:Nitroglycerin significantly reduces the time to sensory and motor block onset,while rocuronium is more effective in prolonging the time of motor block.Although there is no difference between nitroglycerin and rocuronium respecting the pain score and opioid need administration,nitroglycerin is associated with a higher prevalence of medication side effects.Therefore,both nitroglycerin and rocuronium can be used as adjuvant for IVRA.The final choice relies on patients’conditions and anesthesiologists’judgment.

Amylase intrapancreatic infusion delays insulin release during an intravenous glucose tolerance test,proof of acini–islet–acinar interactions

BACKGROUND The possible existence of an acini–islet–acinar(AIA)reflex,involving mutual amylase and insulin interactions,was investigated in the current acute experiment on pigs.AIM To confirm the existence of an AIA reflex and justify the placement of the exocrine and endocrine pancreatic components within the same organ.METHODS The study was performed on six pigs under general anesthesia.An intravenous glucose tolerance test was performed,with a bolus infusion of 50%glucose to the jugular vein,while amylase(5000 U/kg)or vehicle intrapancreatic infusions were administered via the pancreaticoduodenalis cranialis artery during 30 min with a 1 mL/min flow rate.RESULTS The amylase infusion to pancreatic arterial circulation inhibited and delayed the insulin release peak which is usually associated with the highest value of blood glucose and is typically observed at 15 min after glucose infusion,for>1 h.The intrapancreatic infusion of the vehicle(saline)did not have any effect on the time frame of insulin release.Infusion of 1%bovine serum albumin changed the insulin release curve dramatically and prolonged the high range of insulin secretion,far beyond the glucose peak.CONCLUSION Intrapancreatic arterial infusion of amylase interrupted the integrated glucose–insulin interactions.This confirms an AIA reflex and justifies placement of the exocrine and endocrine pancreatic components within the same organ.

Research on the Causes and Nursing Interventions of Extravasation During Intravenous Infusion

Intravenous infusion,a common clinical drug treatment method,is widely used in the treatment of various diseases.Due to the invasive nature of puncture during intravenous infusion,patients may inevitably experience resistance and tension when facing nursing staff performing infusion procedures.Additionally,the complexity of the nursing staff’s work and the impact of the infusion therapy environment can exacerbate the tension between nurses and patients,leading to risks such as drug leakage and needlestick injuries.This article focuses on the factors influencing extravasation during intravenous infusion and elaborates on how high-quality nursing interventions can reduce the incidence of adverse events during intravenous infusion.These interventions aim to improve patient satisfaction with intravenous infusion nursing care and ensure the safety of intravenous infusion procedures.

Intravenous drug abuse and tricuspid valve endocarditis: Growing trends in the Middle East Gulf region

Traditionally, tricuspid valve endocarditis is uncommon in the Middle East region. However, recent global data indicate growing trends in the use of illicit drug abuse, specifically injectable heroin, in the Middle East Gulf region. The presence of many transit port services in the Middle East Gulf States has led to smuggling of substance abuse drugs in the region. The Middle East Gulf States, currently a transit market, are also becoming a growing consumer market in view of the increased substance abuse in the youth. However, there is a paucity of data with respect to the prevalence or incidence of tricuspid valve endocarditis in the region, probably due to underdiagnosis or underreporting. A high index of suspicion of tricuspid valve endocarditis is essential in patients with a history of intravenous drug abuse. This article reviews the epidemiology of illicit drug abuse in the Middle East Gulf region, as well as the diagnosis and treatment of tricuspid valve endocarditis, and calls for all physicians in the region to be vigilant while dealing with intravenous drug abuse.

BS-SC Model:A Novel Method for Predicting Child Abuse Using Borderline-SMOTE Enabled Stacking Classifier

For a long time,legal entities have developed and used crime prediction methodologies.The techniques are frequently updated based on crime evaluations and responses from scientific communities.There is a need to develop type-based crime prediction methodologies that can be used to address issues at the subgroup level.Child maltreatment is not adequately addressed because children are voiceless.As a result,the possibility of developing a model for predicting child abuse was investigated in this study.Various exploratory analysis methods were used to examine the city of Chicago’s child abuse events.The data set was balanced using the Borderline-SMOTE technique,and then a stacking classifier was employed to ensemble multiple algorithms to predict various types of child abuse.The proposed approach successfully predicted crime types with 93%of accuracy,precision,recall,and F1-Score.The AUC value of the same was 0.989.However,when compared to the Extra Trees model(17.55),which is the second best,the proposed model’s execution time was significantly longer(476.63).We discovered that Machine Learning methods effectively evaluate the demographic and spatial-temporal characteristics of the crimes and predict the occurrences of various subtypes of child abuse.The results indicated that the proposed Borderline-SMOTE enabled Stacking Classifier model(BS-SC Model)would be effective in the real-time child abuse prediction and prevention process.

Child Abuse during the Pandemic and Trauma-Informed Care: A Review of Evidence-Based Literature

Abuse of infants and children is a public health problem that warrants immediate attention. It is estimated that over 7 million children are affected by child abuse yearly, with the highest rate of abuse in those less than one year of age. Approximately 60% of child abuse victims are children under the age of three years, making infants and young children a particularly vulnerable population. Interventions targeting the perinatal period can be effective in mitigating child abuse, including parent education programs and trauma-informed care services. This paper provides an overview of the current evidence base related to child abuse following the COVID-19 pandemic, with a focus on prevention and intervention strategies that can be utilized to increase caregiver support and reduce child abuse rates during the perinatal period.

Comparison of different approaches for direct coupling of solid-phase microextraction to mass spectrometry for drugs of abuse analysis in plasma

The direct coupling of solid-phase microextraction(SPME)to mass spectrometry(MS)(SPME-MS)has proven to be an effective method for the fast screening and quantitative analysis of compounds in complex matrices such as blood and plasma.In recent years,our lab has developed three novel SPME-MS techniques:SPME-microfluidic open interface-MS(SPME-MOI-MS),coated blade spray-MS(CBS-MS),and SPME-probe electrospray ionization-MS(SPME-PESI-MS).The fast and high-throughput nature of these SPME-MS technologies makes them attractive options for point-of-care analysis and anti-doping testing.However,all these three techniques utilize different SPME geometries and were tested with different MS instruments.Lack of comparative data makes it difficult to determine which of these methodologies is the best option for any given application.This work fills this gap by making a comprehensive comparison of these three technologies with different SPME devices including SPME fibers,CBS blades,and SPME-PESI probes and SPME-liquid chromatography-MS(SPME-LC-MS)for the analysis of drugs of abuse using the same MS instrument.Furthermore,for the first time,we developed different desorption chambers for MOI-MS for coupling with SPME fibers,CBS blades,and SPME-PESI probes,thus illustrating the universality of this approach.In total,eight analytical methods were developed,with the experimental data showing that all the SPME-based methods provided good analytical performance with R^(2)of linearities larger than 0.9925,accuracies between 81%and 118%,and good precision with an RSD%≤13%.

Double pigtail catheter reduction for seriously displaced intravenous infusion port catheter:A case report

BACKGROUND Implanted intravenous infusion port(TIAP)is mainly used for patients who need central venous infusion and poor peripheral vascular conditions.With the advantages of easy to carry,long maintenance cycle,few complications and excellent quality of life,it has been widely used in the fields of malignant tumor chemotherapy,parenteral nutrition support and repeated blood collection.Implanted intravenous infusion port(IVAP)dislocation can have significant complications if not recognised and reinstated immediately.CASE SUMMARY A 24-year-old man was treated with adjuvant chemotherapy for osteosarcoma.Severe displacement of IVAP catheter was found by chest X-ray examination.The IVAP cannot be used normally.Therefore,we conducted an emergency procedure to reset the catheter through double pigtail catheters,the operation was successful and the infusion port was restored.CONCLUSION When IVAP catheter displacement cannot be reset by conventional techniques,two pigtail catheters can be successfully used instead.

Analysis of Capacity Decay, Impedance, and Heat Generation of Lithium-ionBatteries Experiencing Multiple Simultaneous Abuse Conditions

Abuse of Lithium-ion batteries,both physical and electrochemical,can lead to significantly reduced operational capabilities.In some instances,abuse can cause catastrophic failure,including thermal runaway,combustion,and explosion.Many different test standards that include abuse conditions have been developed,but these generally consider only one condition at a time and only provide go/no-go criteria.In this work,different types of cell abuse are implemented concurrently to determine the extent to which simultaneous abuse conditions aggravate cell degradation and failure.Vibrational loading is chosen to be the consistent type of physical abuse,and the first group of cells is cycled at different vibrational frequencies.The next group of cells is cycled at the same frequencies,with multiple charge pulses occurring during each discharge.The final group of cells is cycled at the same frequencies,with a partial nail puncture occurring near the beginning of cycling.The results show that abusing cells with vibrational loading or vibrational loading with current pulses does not cause a significant decrease in operational capabilities while abusing cells with vibrational loading and a nail puncture drastically reduces operational capabilities.The cells with vibration only experience an increase in internal resistance by a factor of 1.09–1.26,the cells with vibration and current pulses experience an increase in internal resistance by a factor of 1.16–1.23,and all cells from each group reach their rated lifetime of 500 cycles without reaching their end-of-life capacity.However,the cells with vibration and nail puncture experience an increase in internal resistance by a factor of 6.83–22.1,and each cell reaches its end-of-life capacity within 50 cycles.Overall,the results show that testing multiple abuse conditions simultaneously provides a better representation of the extreme limitations of cell operation and should be considered for inclusion in reference test standards.

Efficacy and safety of intravenous tranexamic acid in total shoulder arthroplasty:A meta-analysis

BACKGROUND Total shoulder arthroplasty(TSA)results in a large amount of perioperative blood loss due to severe trauma.AIM To investigate the safety and efficacy of intravenous tranexamic acid(TXA)in TSA.METHODS We searched the PubMed,Cochrane Library,Embase and Web of Science databases for randomized controlled trials(RCTs)on the use of TXA in TSA.And all the results were checked and assessed by Reference Citation Analysis(https://www.referencecitationanalysis.com/).A meta-analysis was performed with Review Manager 5.3 to calculate the odds ratio(OR)or weighted mean difference(WMD)of related outcome indicators.RESULTS A total of 5 RCTs with level 1 evidence were included.There were 369 cases,with 186 in the TXA group and 183 in the placebo group.The meta-analysis showed that TXA can significantly reduce total blood loss during the perioperative period[WMD=-249.56,95%confidence interval(CI):-347.6 to-151.52,P<0.0001],and the incidence of adverse reactions was low(OR=0.36,95%CI:0.16-0.83,P=0.02).Compared with the placebo group,the TXA group had significantly less total haemoglobin loss(WMD=-34.39,95%CI:-50.56 to-18.22),less haemoglobin fluctuation before and after the operation(WMD=-0.6,95%CI:-0.93 to-0.27)and less 24-h drain output(WMD=-136.87,95%CI:-165.87 to-106.49).There were no significant differences in the operation time(P=0.11)or hospital length of stay(P=0.30)between the two groups.CONCLUSION The application of intravenous TXA in the perioperative period of TSA can significantly reduce the total volume of perioperative blood loss and reduce the incidence of adverse reactions,so TXA is worthy of widespread clinical use.

Child abuse and psychopathy: Interplay, gender differences and biological correlates

Child abuse is an important source of mental and physical adverse consequences for victims,their family,and their community.The impact of violence during childhood on the development of the victim is a very sensitive theme.Other than internalizing symptoms,it is interesting to analyze the possibility that a victim may assume the role of persecutor.With this aim,we evaluate Literature and examine the interplay among different types of child abuse(emotional neglect,emotional abuse,physical neglect,physical abuse and sexual abuse)and the development of psychopathy.We consider the role of post-traumatic stress disorder and that of personal environment as potential mediators between abuse and psychopathy.Furthermore,an in-depth analysis on possible differences due to the victim's gender is performed.Finally,analysis focused on genetic variants,such as the polymorphism of 5HTT and MAO-A,or a biological alteration,like the difference in daily cortisol levels that could be related to the development of psychopathy after a trauma.

Progress in oncolytic viruses modified with nanomaterials for intravenous application

In oncolytic virus(OV)therapy,a critical component of tumor immunotherapy,viruses selectively infect,replicate within,and eventually destroy tumor cells.Simultaneously,this therapy activates immune responses and mobilizes immune cells,thereby eliminating residual or distant cancer cells.However,because of OVs’high immunogenicity and immune clearance during circulation,their clinical applications are currently limited to intratumoral injections,and their use is severely restricted.In recent years,numerous studies have used nanomaterials to modify OVs to decrease virulence and increase safety for intravenous injection.The most commonly used nanomaterials for modifying OVs are liposomes,polymers,and albumin,because of their biosafety,practicability,and effectiveness.The aim of this review is to summarize progress in the use of these nanomaterials in preclinical experiments to modify OVs and to discuss the challenges encountered from basic research to clinical application.

Training needs in intravenous infusion care for children in China:A cross-sectional study

Aim:This study aims to evaluate demands for general and pharmacological knowledge and training related to intravenous(IV)therapy among pediatric nurses.Materials and Methods:This multicentric cross‑sectional study involved 12,707 pediatric nurses from 100 hospitals in China.A questionnaire was used to assess information about IV drug administration training received,and the demands for pharmacology‑related knowledge,and corresponding methods of acquisition.A generalized linear model using Logit link function was employed to assess relationships between factors and multivariate analysis was conducted.Results:More than 99%of participants showed their training demands for IV therapy training.Pediatric nurses’demands and methods for acquiring IV therapy knowledge and the knowledge related to IV therapy pharmacology have significant differences in social demographic factors,previous knowledge,whether they have received training or not,and other factors(all P<0.05).Received a needlestick injury in the past month(P=0.007)and knowledge acquired through in‑hospital or out‑of‑hospital training(P=0.039)were factors that reduced the demands for methods to acquire further pharmacology‑related knowledge of IV therapy.Working in internal medicine(P=0.025)and not having experienced a needlestick injury in the past year(P=0.007)reduced the demands for IV therapy knowledge.Attended hospital(P=0.007)or departmental meetings(P=0.009),being pediatric primary nurses(P=0.044),and studied special IV guidelines(P=0.006)reduced the desire for methods to acquire IV therapy knowledge.Conclusion:There was a high demand for greater general and pharmacological knowledge related to IV therapy among pediatric nurses.Resources should be coordinated to provide ongoing training to nurses to improve the quality of IV care.

Oral Glucose Combined with Short-Term Intravenous Nutrition for the Prevention of Hypoglycemia after Endoscopic Colorectal Polypectomy

Objective: To investigate the effect of oral glucose combined with short-term intravenous nutrition on the prevention of hypoglycemia after endoscopic colorectal polypectomy and to provide guidance for better management of such patients. Methods: 860 patients who underwent endoscopic colorectal polypectomy for colorectal polyps in the Department of Gastroenterology of the First Affiliated Hospital of Yangtze University from January 2020 to December 2021 were selected for the study. The patients were divided into experimental and control groups according to the random number table method, with 430 patients in each group. In the control group, 3 L of polyethylene glycol electrolyte dispersion was used for preoperative intestinal preparation and postoperative fasting was performed routinely for 24 h. Short-term intravenous nutrition support was provided by rehydration, and finger blood glucose was monitored at 1, 4, and 8 h after intravenous infusion or when there were symptoms such as panic and cold sweat;in the experimental group, oral glucose intervention was implemented on the basis of the control group. The incidence of postoperative hypoglycemia, quality of bowel preparation, and tolerance of patients during bowel preparation were compared between the 2 groups. Results: The incidence of postoperative blood glucose Conclusion: Based on the present study population, oral glucose combined with short-term intravenous nutrition can effectively prevent the incidence of hypoglycemia in patients after endoscopic colorectal polypectomy;however, this was limited to a single-center study and the number of cases was small.
