FUZZY KNOWLEDGE ACQUIREMENT IN GATE DESIGN

In order to reduce time and cost in engineering design, such as gate design, integral field knowledge must be obtained efficiently. After studying ID3 and its improved methods, a new algorithm(Fuzzy ID3 ) and its main concepts are presented to overcome some disadvantage in classical ID3 algorithms. In its application of gate design, fuzzy knowledge gotten by the new algorithm is more efficient than the knowledge by other ID3 algorithms, the set of fuzzy knowledge is much smaller than that of knowledge by classical ID3 algorithms. On the other hand, fuzzy knowledge represents field data more naturally to the way of bar thinking and more robust in tolerating imprecise, conflicting and missing information

Effective Trace Acquirement during Product Information Diffusion and Application

Information dissemination has become part of people’s daily communication and there is great interest for both academic and industrial communities. Most previous studies have focused on the strategy and mechanisms. The methods controlling the process of information diffusion have rarely been studied. Thus, previous studies have failed to effectively mine the value of product information diffusion on social networks. In this study, based on the information diffusion product in consumer self-organized social networks, the control of the product information diffusion process was explored. The node identification principle of the QR code sender designed in this study and the linked list that associated information with specific nodes allowed the acquisition of effective traces in long-chain transmission from the information source to the value nodes, and solved user information disclosure during the transmission process. This method was applied to the tracing system of defective vehicles, achieving accurate recall of defective vehicles.

Immediate secondary rhinoplasty using a folded dermofat graft for resolving complications related to silicone implants: A case report

BACKGROUND Various surgical techniques have been developed to enhance the nose shapes of Asian patients.Silicone implant augmentation rhinoplasty is widely used because it is relatively easy to perform and often yields satisfactory outcomes.However,this technique may lead to complications,including ischemia,necrosis,and over-augmentation.The most appropriate management of these complications,including infection,is immediate implant removal and revision surgery once the accompanying inflammation has healed.Occasionally,the patient may experience distress from nasal deformities during the intervention period.CASE SUMMARY Herein,we describe the case of a patient who underwent a secondary dorsal augmentation,with a folded dermofat graft harvested from the inguinal area and simultaneous implant removal,successfully preventing dimpling of the nasal deformity.CONCLUSION This surgical method can effectively manage implant-related complications following augmentation rhinoplasty using a silicone implant and provide satis-factory patient outcomes.

Magnetic resonance imaging of extraocular rectus muscles abnormalities in acute acquired concomitant esotropia

AIM:To investigate the difference of medial rectus(MR)and lateral rectus(LR)between acute acquired concomitant esotropia(AACE)and the healthy controls(HCs)detected by magnetic resonance imaging(MRI).METHODS:A case-control study.Eighteen subjects with AACE and eighteen HCs were enrolled.MRI scanning data were conducted in target-controlled central gaze with a 3-Tesla magnetic resonance scanner.Extraocular muscles(EOMs)were scanned in contiguous image planes 2-mm thick spanning the EOM origins to the globe equator.To form posterior partial volumes(PPVs),the LR and MR cross-sections in the image planes 8,10,12,and 14 mm posterior to the globe were summed and multiplied by the 2-mm slice thickness.The data were classified according to the right eye,left eye,dominant eye,and non-dominant eye,and the differences in mean cross-sectional area,maximum cross-sectional area,and PPVs of the MR and LR muscle in the AACE group and HCs group were compared under the above classifications respectively.RESULTS:There were no significant differences between the two groups of demographic characteristics.The mean cross-sectional area of the LR muscle was significantly greater in the AACE group than that in the HCs group in the non-dominant eyes(P=0.028).The maximum cross-sectional area of the LR muscle both in the dominant and non-dominant eye of the AACE group was significantly greater than the HCs group(P=0.009,P=0.016).For the dominant eye,the PPVs of the LR muscle were significantly greater in the AACE than that in the HCs group(P=0.013),but not in the MR muscle(P=0.698).CONCLUSION:The size and volume of muscles dominant eyes of AACE subjects change significantly to overcome binocular diplopia.The LR muscle become larger to compensate for the enhanced convergence in the AACE.

Botulinum toxin type A in treating early-stage patients with small-angle acute acquired comitant esotropia

AIM:To investigate botulinum toxin A(BTXA)efficacy on small-angle(≤25Δ)acute acquired concomitant esotropia(AACE)in early-stage patients.METHODS:The electronic medical record data of AACE patients during March 2019 and June 2023 were collected in this retrospective and hospital-based cohort study.A total of 72 small-angle AACE patients received BTXA extraocular muscle injection.Patients were grouped by onset-to-treatment time(Group A:≤6mo,Group B:>6mo).Deviation of esotropia,eye alignment and stereopsis were analyzed at the period of pre/post-injection(1wk,1,3,and 6mo).Orthophoria rate at 6mo(horizontal deviation<10Δand binocular single vision)were considered as outcome index.RESULTS:There were no significant baseline differences(P>0.05)between two groups except onset-to-treatment time(2mo vs 11mo,P<0.001).Higher orthophoria rates were in Group A at last follow-up(94.74%vs 73.53%,P=0.013).Post-BTXA deviations of two groups at 1mo showed no difference(P>0.05);while in 3 and 6mo Group A was significantly smaller than group B(all P<0.001).No statistically significant differences were observed among all post-BTXA deviations of near and distance in Group A.In Group B,deviation at 3mo(near:2Δvs 0,P<0.001;distance:4Δvs 0,P<0.001)and 6mo(near:6Δvs 0,P<0.001;distance:6Δvs 0,P<0.001)was significant increased compared to deviation at 1wk after treatment.Group A showed better stereopsis recovery in last follow-up compared to Group B(80″vs 200″,P=0.002).Both groups obtained improved stereopsis after treatment(Group A:80″vs 300″,P<0.001;Group B:200″vs 300″,P=0.037).CONCLUSION:BTXA is effective for AACE with small deviation(≤25Δ)in early stage.Delayed treatment(>6mo)may reduce BTXA efficacy.Early BTXA intervention benefits long-term eye alignment and stereopsis recovery.

Knowledge of Hospital Acquired Infections (HAIs) among Medical Students in a Tertiary Hospital in Jos North Local Government Area, Plateau State, Nigeria

Background: Hospital Acquired Infections (HAIs) remain a common cause of death, functional disability, emotional suffering and economic burden among hospitalized patients. Knowledge of HAIs is important in its prevention and control. This study seeks to assess the knowledge of Hospital Acquired Infections (HAIs) among medical students in a Tertiary Hospital in Jos North Local Government Area, Plateau State, Nigeria. Methods: This was a descriptive cross-sectional study done in October 2019 among clinical medical students using a Multistage sampling technique. Data was collected using a self-administered structured questionnaire and analyzed using the IBM SPSS 20 (Statistical Package for the Social Sciences). Ethical approval was granted by Bingham University Teaching Hospital, Ethics Committee, Jos, Plateau State. Results: A total of 219 students in the clinical arm of the College of Medicine and Health Sciences were selected. A higher proportion (97.7%) of respondents knew about Hospital Acquired Infections and 85.4% knew that Hospital Acquired infections occur in the hospital, and (86.3%) considered patients contagious with half (58.9%) considered patients as the most important source of HAIs, followed by care givers (13.2%), then doctors including medical students and interns (10.0%) and lastly nurses (8.7%). The majority of respondents (70.8%) considered Surgical Wound Infections to be the most commonly occurring HAI, followed by UTIs (69.9%), RTIs (61.2%), BSIs (37.0%) and others (0.9%). The clinical thermometer was the instrument that most commonly transmits HAIs (82.6%), then followed by stethoscope (62.1%), white coats (53.9%), and blood pressure cuff (51.1%). Most respondents knew the infectious substances, like blood (96.3%), nasal discharge (82.6%), saliva (85.3%), and faeces (79.4%) transmitted HAIs, 72.6% of the respondents said that they were aware of the recommended hand washing techniques by WHO. Conclusion: The majority of students 91.3% had good knowledge while 8.7% had poor knowledge of HAIs. Lower classes had more respondents with poor knowledge. This finding was statistically significant (p = 0.002, Chi-square 12.819). Students are encouraged to keep up the level of knowledge they have about HAIs. These students can help improve the knowledge of those whose knowledge level is low. Government and NGOs should support sponsorship for capacity-building events targeted at HAIs for healthcare workers and medical students.

Factors Associated with Antiretroviral Therapy Defaulting among Adult Patients Receiving Care at Chikankata Mission Hospital, Chikankata District, Zambia

Background: Defaulting on antiretroviral therapy has been identified as the most important factor contributing to the antiretroviral therapy failure rate. This study aimed to investigate factors associated with defaulting on antiretroviral therapy among adult patients receiving care at Chikankata Mission Hospital antiretroviral therapy clinic. Method: Cross-sectional analytical study on 385 participants selected by a computer generated random numbers technique of simple random sampling from among the patients receiving antiretroviral therapy at Chikankata Mission Hospital. Data collected were processed and analysed using Statistical Package for Social Science version 27. Univariate and backward multivariable logistic regression analysis was performed to identify factors associated with antiretroviral therapy defaulting. The level of significance was set at 5% with a confidence level of 95%. Results: Over half (58.4%) of the study participants defaulted on antiretroviral therapy. About 65.8% of study participants indicated improved health as the reason they defaulted on antiretroviral therapy. Most participants indicated that it was important to always go for antiretroviral therapy services (Adjusted Odds Ratio 1.95;95% Confidence Interval: [1.14 - 3.33], p = 0.015). Very few participants indicated poor family support for antiretroviral therapy services (Adjusted Odds Ratio 4.08;95% Confidence Interval: [2.02 - 8.23], p Conclusion: Defaulting on antiretroviral therapy continues to be a significant problem and needs to be addressed as a matter of priority. More counselling and awareness-raising programmes are required to improve knowledge and understanding on the importance of attending scheduled antiretroviral therapy clinics and services as well as the consequences of defaulting on antiretroviral therapy.

Neuropsychological Profile of a Patient with Acquired Brain Damage Following Vascular Lesion of the Left Anterior Cingulate Cortex

Stroke is a physiological alteration associated with changes in blood flow that can result in sudden-onset cognitive impairment. It has a heterogenous clinical presentation with varying degrees of severity correlated with specific central nervous system zones or areas, and its prognosis is uncertain. This case study describes a 62-year-old male patient with acquired brain damage of the anterior cingulate cortex as a result of an ischemic event in the territory of the left anterior cerebral artery. Cognitive function was assessed using the neuropsychological executive function and frontal lobe test battery (BANFE-2) as well as other neuropsychological tests. The results show a profile of higher mental functions characterized by the presence of dysexecutive syndrome with marked behavioral alteration and diencephalic amnesia. .

Steroids in acute respiratory distress syndrome:A panacea or still a puzzle?

Acute respiratory distress syndrome(ARDS)is a unique entity marked by various etiologies and heterogenous pathophysiologies.There remain concerns regarding the efficacy of particular medications for each severity level apart from respiratory support.Among several pharmacotherapies which have been examined in the treatment of ARDS,corticosteroids,in particular,have demonstrated potential for improving the resolution of ARDS.Nevertheless,it is imperative to consider the potential adverse effects of hyperglycemia,susceptibility to hospital-acquired infections,and the development of intensive care unit acquired weakness when administering corticosteroids.Thus far,a multitude of trials spanning several decades have investigated the role of corticosteroids in ARDS.Further stringent trials are necessary to identify particular subgroups before implementing corticosteroids more widely in the treatment of ARDS.This review article provides a concise overview of the most recent evidence regarding the role and impact of corticosteroids in the management of ARDS.

Increasing role of post-intensive care syndrome in quality of life of intensive care unit survivors

In this editorial we comment on the detrimental consequences that post-intensive care syndrome(PICS)has in the quality of life of intensive care unit(ICU)survivors,highlighting the importance of early onset of multidisciplinary rehabilitation from within the ICU.Although,the syndrome was identified and well described early in 2012,more awareness has been raised on the long-term PICS related health problems by the increased number of coronavirus disease 2019 ICU survivors.It is well outlined that the syndrome affects both the patient and the family and is described as the appearance or worsening of impairment in physical,cognitive,or mental health as consequence of critical illness.PICS was described in order:(1)To raise awareness among clinicians,researchers,even the society;(2)to highlight the need for a multilevel screening of these patients that starts from within the ICU and continues after discharge;(3)to present preventive strategies;and(4)to offer guidelines in terms of rehabilitation.An early multidisci-plinary approach is the key element form minimizing the incidence of PICS and its consequences in health related quality of life of both survivors and their families.

Antibiotic resistance in patients with liver cirrhosis:Prevalence and current approach to tackle

Regardless of etiology,complications with bacterial infection in patients with cirrhosis are reported in the range of 25%-46%according to the most recent data.Due to frequent episodes of bacterial infection and repetitive antibiotic treatment,most often with broad-spectrum gram negative coverage,patients with cirrhosis are at increased risk of encountering multidrug resistant bacteria,and this raises concern.In such patients,extended-spectrum beta-lactamase and AmpCproducing Enterobacterales,methicillin-or vancomycin-resistant Staphylococcus aureus,vancomycin-resistant Enterococci,carbapenem-resistant Pseudomonas aeruginosa,and Acinetobacter baumannii,all of which are difficult to treat,are the most common.That is why novel approaches to the prophylaxis and treatment of bacterial infections to avoid antibiotic resistance have recently been developed.At the same time,our knowledge of resistance mechanisms is constantly updated.This review summarizes the current situation regarding the burden of antibiotic resistance,including the prevalence and mechanisms of intrinsic and acquired resistance in bacterial species that most frequently cause complications in patients with liver cirrhosis and recent developments on how to deal with multidrug resistant bacteria.

Emerging role of computed tomography coronary angiography in evaluation of children with Kawasaki disease

Coronary artery abnormalities are the most important complications in children with Kawasaki disease(KD).Two-dimensional transthoracic echocardiography currently is the standard of care for initial evaluation and follow-up of children with KD.However,it has inherent limitations with regard to evaluation of mid and distal coronary arteries and,left circumflex artery and the poor acoustic window in older children often makes evaluation difficult in this age group.Catheter angiography(CA)is invasive,has high radiation exposure and fails to demonstrate abnormalities beyond lumen.The limitations of echocardiography and CA necessitate the use of an imaging modality that overcomes these problems.In recent years advances in computed tomography technology have enabled explicit evaluation of coronary arteries along their entire course including major branches with optimal and acceptable radiation exposure in children.Computed tomography coronary angiography(CTCA)can be performed during acute as well as convalescent phases of KD.It is likely that CTCA may soon be considered the reference standard imaging modality for evaluation of coronary arteries in children with KD.

A case of unusual acquired factor V deficiency

Dear editor,Factor V deficiency is a rare bleeding disorder,which includes congenital and acquired factor V deficiencies.Congenital factor V deficiency(CFVD)is an autosomal recessive disorder with an estimated prevalence of 1:1,000,000.[1]However,acquired factor V deficiency(AFVD)is even rarer.

Activation-induced pyroptosis contributes to the loss of MAIT cells in chronic HIV-1 infected patients

Background: Mucosal-associated invariant T(MAIT) cells are systemically depleted in human immunodeficiency virus type 1(HIV-1) infected patients and are not replenished even after successful combined antiretroviral therapy(cART).This study aimed to identify the mechanism underlying MAIT cell depletion.Methods: In the present study, we applied flow cytometry, single-cell RNA sequencing and immunohistochemical staining to evaluate the characteristics of pyroptotic MAIT cells in a total of 127 HIV-1 infected individuals, including 69 treatment-naive patients, 28 complete responders, 15 immunological non-responders, and 15 elite controllers, at the Fifth Medical Center of Chinese PLA General Hospital, Beijing, China.Results: Single-cell transcriptomic profiles revealed that circulating MAIT cells from HIV-1 infected subjects were highly activated, with upregulation of pyroptosis-related genes. Further analysis revealed that increased frequencies of pyroptotic MAIT cells correlated with markers of systemic T-cell activation, microbial translocation, and intestinal damage in cART-naive patients and poor CD4+ T-cell recovery in long-term cART patients. Immunohistochemical staining revealed that MAIT cells in the gut mucosa of HIV-1 infected patients exhibited a strong active gasdermin-D(GSDMD, marker of pyroptosis) signal near the cavity side, suggesting that these MAIT cells underwent active pyroptosis in the colorectal mucosa. Increased levels of the proinflammatory cytokines interleukin-12(IL-12) and IL-18 were observed in HIV-1 infected patients. In addition, activated MAIT cells exhibited an increased pyroptotic phenotype after being triggered by HIV-1 virions, T-cell receptor signals, IL-12 plus IL-18, and combinations of these factors, in vitro.Conclusions: Activation-induced MAIT cell pyroptosis contributes to the loss of MAIT cells in HIV-1 infected patients,which could potentiate disease progression and poor immune reconstitution.

Acquired immunity and Alzheimer's disease

Alzheimer’s disease(AD) is an age-related neurodegenerative disease characterized by progressive cognitive defects. The role of the central immune system dominated by microglia in the progression of AD has been extensively investigated. However, little is known about the peripheral immune system in AD pathogenesis.Recently, with the discovery of the meningeal lymphatic vessels and glymphatic system, the roles of the acquired immunity in the maintenance of central homeostasis and neurodegenerative diseases have attracted an increasing attention. The T cells not only regulate the function of neurons, astrocytes, microglia, oligodendrocytes and brain microvascular endothelial cells, but also participate in the clearance of β-amyloid(Aβ) plaques. Apart from producing antibodies to bind Aβ peptides, the B cells affect Aβ-related cascades via a variety of antibodyindependent mechanisms. This review systemically summarizes the recent progress in understanding pathophysiological roles of the T cells and B cells in AD.

Analysis of independent risk factors for acute acquired comitant esotropia

comitant esotropia(AACE).METHODS:A retrospective cohort study was conducted by analyzing 83 patients(case group)with AACE who underwent strabismus correction surgery from January 1,2021 to June 30,2022.Totally 73 outpatient volunteers were recruited during the same period as the normal control group.The case group’s binocular vision time,near and distance esotropia angle,and near stereo vision function were recorded,and the age,gender,refractive status,and best-corrected visual acuity(BCVA)of both groups were analyzed.Additionally,multiple logistic regression analysis was conducted using an eye usage condition questionnaire to determine the independent risk factors for AACE.RESULTS:In the case group,61 patients(73.49%)had myopia,with a mean equivalent spherical power(SE)of-3.35±3.31 D(range:+2.75 to-10.62 D)of the right eye and-2.87±3.35 D(range:+2.75 to-11.12 D)of the left eye.The average duration of diplopia in the case group was 29.83±35.72mo,of which 80 patients(96.39%)were primarily with distance diplopia.The near and distance esotropia angle after wearing glasses were 52.36±20.95 prism degree(PD)and 56.71±19.54 PD,respectively,and there was no statistically significant difference between the two(t=1.38,P=0.169).The incidence of improper glasses wearing and unhealthy eye habits in the case group was significantly higher than those in the control group(P<0.05).Close-up work without glasses[β=2.30,odds ratio(OR)=10,95%confidence interval(CI)2.35-42.51,P=0.002]and near work in supine position(β=1.80,OR=6.02,95%CI 3.29-11.02,P<0.001)were independent risk factors for AACE.CONCLUSION:Patients with AACE mainly present with distance diplopia,and there is a high degree of variation in myopia.Near work without wearing glasses and in supine position are independent risk factors for AACE.

The default mode network is affected in the early stage of simian immunodeficiency virus infection:a longitudinal study

Acquired immune deficiency syndrome infection can lead to cognitive dysfunction represented by changes in the default mode network.Most recent studies have been cross-sectional and thus have not revealed dynamic changes in the default mode network following acquired immune deficiency syndrome infection and antiretroviral therapy.Specifically,when brain imaging data at only one time point are analyzed,determining the duration at which the default mode network is the most effective following antiretroviral therapy after the occurrence of acquired immune deficiency syndrome.However,because infection times and other factors are often uncertain,longitudinal studies cannot be conducted directly in the clinic.Therefore,in this study,we performed a longitudinal study on the dynamic changes in the default mode network over time in a rhesus monkey model of simian immunodeficiency virus infection.We found marked changes in default mode network connectivity in 11 pairs of regions of interest at baseline and 10 days and 4 weeks after virus inoculation.Significant interactions between treatment and time were observed in the default mode network connectivity of regions of interest pairs area 31/V6.R and area 8/frontal eye field(FEF).L,area 8/FEF.L and caudal temporal parietal occipital area(TPOC).R,and area 31/V6.R and TPOC.L.ART administered 4 weeks after infection not only interrupted the progress of simian immunodeficiency virus infection but also preserved brain function to a large extent.These findings suggest that the default mode network is affected in the early stage of simian immunodeficiency virus infection and that it may serve as a potential biomarker for early changes in brain function and an objective indicator for making early clinical intervention decisions.

Acquired haemophilia as a complicating factor in treatment of nonmuscle invasive bladder cancer:A case report

BACKGROUND Acquired haemophilia(AH)is a serious autoimmune haematological disease caused by the production of auto-antibodies against coagulation factor VIII.In some patients,AH is associated with a concomitant malignancy.In case of surgical intervention,AH poses a high risk of life-threatening bleeding.CASE SUMMARY A 60-year-old female patient with multiple recurrences of non-muscle invasive bladder cancer underwent transurethral tumour resection.A severe haematuria developed postoperatively warranting two endoscopic revisions;however,no clear source of bleeding was identified in the bladder.Subsequent haematological examination established a diagnosis of AH.Treatment with factor VIII inhibitor bypass activity and immunosuppressive therapy was initiated immediately.The patient responded well to the therapy and was discharged from the hospital 21 d after the primary surgery.At the 38-mo follow-up,both AH and bladder cancer remained in complete remission.CONCLUSION AH is a rare,life-threatening haematological disease.AH should be considered in patients with persistent severe haematuria or other bleeding symptoms,especially if combined with isolated activated partial thromboplastin time prolongation.

Acute acquired concomitant esotropia with congenital paralytic strabismus:A case report

BACKGROUND An unusual case of acute acquired concomitant esotropia(AACE)with congenital paralytic strabismus in the right eye is reported.CASE SUMMARY A 23-year-old woman presented with complaints of binocular diplopia and esotropia of the right eye lasting 4 years and head tilt to the left since 1 year after birth.The Bielschowsky head tilt test showed right hypertropia on a right head tilt.She did not report any other intracranial pathology.A diagnosis of AACE and right congenital paralytic strabismus was made.Then,she underwent medial rectus muscle recession and lateral rectus muscle resection combined with inferior oblique muscle myectomy in the right eye.One day after surgery,the patient reported that she had no diplopia at either distance or near fixation and was found to be orthophoric in the primary position;furthermore,her head posture immediately and markedly improved.CONCLUSION In future clinical work,in cases of AACE combined with other types of strabismus,we can perform conventional single surgery for both at the same time,and the two types of strabismus can be solved simultaneously.
