Prevalence of Helicobacter pylori infection in Chinese military personnel:A cross-sectional,multicenter-based study

BACKGROUND Helicobacter pylori(H.pylori)infection is a prevalent disease encountered in military internal medicine and recognized as the main cause of dyspepsia,gastritis,and peptic ulcer,which are common diseases in military personnel.Current guidelines in China state all patients with evidence of active infection with H.pylori are offered treatment.However,the prevalence of H.pylori infection and its regional distribution in the military population remain unclear,which hinders effective prevention and treatment strategies.Understanding the prevalence of H.pylori infection in the military population will aid in the development of customized strategies to better manage this infectious disease.AIM To investigate the prevalence of H.pylori infection in the Chinese military population in different geographic areas.METHODS This multicenter,retrospective study included 22421 individuals from five tertiary hospitals located in north,east,southwest,and northwest cities of China.H.pylori infection was identified using the urea breath test,which had been performed between January 2020 and December 2021.RESULTS Of the 22421 military service members,7416(33.1%)were urea breath test-positive.The highest prevalence of H.pylori was in the 30-39 years age group for military personnel,with an infection rate of 34.9%.The majority of infected subjects were younger than 40-years-old,accounting for 70.4%of the infected population.The individuals serviced in Lanzhou and Chengdu showed a higher infection prevalence than those in Beijing,Nanjing,and Guangzhou,with prevalence rates of 44.3%,37.9%,29.0%,31.1%,and 32.3%,respectively.CONCLUSION H.pylori infection remains a common infectious disease among military personnel in China and has a relatively high prevalence rate in northwest China.

Health Care Personnel’s Attitude toward Hand Hygiene in Regard to the Prevention of Health-Care Associated Infections: A Cross Sectional Study at the University Hospital Pristine

Background: Hand hygiene is the leading measure for preventing the spread of antimicrobial resistance and reducing healthcare-associated infections, but health care worker compliance with optimal practices remains low in most settings. Objective: The main aim of this paper is to determine findings and start drafting policies in implementing them into practice after finding out nurses’ opinions, beliefs and attitudes toward hand hygiene (HH). Methodology and methods: A cross sectional descriptive and observational study during November 2009. Results: From the total number of 175 health care workers employed in this unit, 67 (38.3%) were observed regarding adherence to hand hygiene. Regarding the knowledge, practices and attitudes of the nurses, data were collected from 54 (50.0%) among 108 nurses in four intensive care units within the University Clinical Centre of Kosovo (UCCK). From research findings, it was concluded that hand hygiene compliance in the intensive care units was low (51.3%). Conclusion: Research results show the necessity of organizing multimodal programs with intensive care units of University Clinical Centre of Kosovo (UCCK) on increase of knowledge level on health-care associated infections (HAI).

Qualitative and semi-quantitative analysis of health-care pharmaceutical products using laser-induced breakdown spectroscopy

Laser-induced breakdown spectroscopy(LIBS) is a sensitive optical technique that is capable of rapid multi-elemental analysis. The development of this technique for elemental analysis of pharmaceutical products may eventually revolutionize the field of human health. Under normal circumstances, the elemental analysis of pharmaceutical products based on chemical methods is time-consuming and complicated. In this investigation, the principal aim is to develop an LIBS-based methodology for elemental analysis of pharmaceutical products. This LIBS technique was utilized for qualitative as well as quantitative analysis of the elements present in Ca-based tablets. All the elements present in the tablets were detected and their percentage compositions were verified in a single shot, using the proposed instrument. These elements(e.g., Ca, Mg, Fe, Zn, and others) were identified by the wavelengths of their spectral lines, which were verified using the NIST database. The approximate amount of each element was determined based on their observed peaks and the result was in exact agreement with the content specification. The determination of the composition of prescription drug for patients is highly important in numerous circumstances. For example, the exploitation of LIBS may facilitate elemental decomposition of medicines to determine the accuracy of the stated composition information. Moreover, the approach can provide element-specific, meaningful, and accurate information related to pharmaceutical products.

Health-care needs of remitted patients with bipolar disorder: A comparison with schizophrenia

AIM To investigate health-care needs and their correlates among patients with remitted bipolar disorder(BD) compared to patients with remitted schizophrenia. METHODS Outpatients with BD(n = 150) and schizophrenia(n = 75) meeting clearly defined remission criteria were included in the study along with their relatives. Diagnostic ascertainment was carried out using the Mini International Neuropsychiatric Interview. Demographic and clinical details were recorded using structured formats. Residual symptoms were assessed using standardized scales. Health-care needs were assessed on two separate scales. The principal instrument employed to assess health-care needs was the Camberwell Assessment of Need-Research version(CAN-R). To further evaluate health-care needs we felt that an additional instrument, which was more relevant for Indian patients and treatment-settings and designed to cover those areas of needs not specifically covered by the CAN-R was required. This instrument with a structure and scoring pattern similar to the CAN-R was used for additional evaluation of needs. Patients' level offunctioning was assessed using the Global Assessment of Functioning Scale and their quality of life(QOL) using the World Health Organization Quality Of Life-BREF version in Hindi.RESULTS An average of 6-7 needs was reported by patients with BD as well as their relatives. Commonly reported needs were in the areas of economic and welfare needs, informational needs, social needs and the need for treatment. According to the CAN-R, both patients and relatives reported that more than 60% of the total needs were being met. However, over 90% of the needs covered by the additional evaluation were unmet according to patients and relatives. Needs in the areas of economic and welfare-benefits, information, company, daytime activities and physical health-care were largely unmet according to patients and relatives. Total, met and unmet needs were significantly higher for schizophrenia, but the most common types of needs were quite similar to BD. Relatives reported more needs than patients with certain differences in the types of needs reported. Level of patients' functioning was the principal correlate of greater total and unmet needs in both groups. Significant associations were also obtained with residual symptoms and QOL.CONCLUSION The presence of unmet needs in remitted patients with BD was an additional marker of the enduring psychosocial impairment characteristic of the remitted phase of BD.

Interpretation of WHO Guideline:Assessing and Managing Children at Primary Health-care Facilities to Prevent overweight and Obesity in the Context of the Double Burden of Malnutrition

Along with the transitions of social and economic development,dietary patterns and physical activity and life-styles,the prevalence of childhood overweight and obesity has increased at an astonishing rate in the past decades,and has become one of the most serious public health challenges.Meanwhile,the stunting rate has declined with slowly pace,while millions of young lives are still be threatened by wasting all over the word.The present situation of Double Burden of Malnutrition should be recognized clearly and addressed seriously,which refers to,the common presence of both obesity and underweight in the same populations,communities and even families.In order to provide guidance on the appropriate assessment and management of infants and children presenting to primary health-care facilities,to reduce the risk of overweight and obesity among children,the Guideline Assessing and Managing Children at Primary Healthcare Facilities to Prevent Overweight and Obesity in the Context of the Double Burden of Malnutrition was developed and released by WHO in 2017 using the procedures outlined in the WHO handbook for guideline development.The WHO Guideline(2017)is intended primarily for use in low-and medium-resource settings where both under-nutrition and obesity are prevalent.In this guideline,there are three prioritized speci c areas and questions for infants and children presenting to primary health-care facilities:anthropometric assessment,care of infants and children with acute or chronic malnutrition,and care of children who are overweight or obese.It is recommended that for infants and children aged<5 years presenting primary health-care facilities,weight and length/height should be measured and evaluate adequately,general nutrition and physical activity counselling should be provided for related caregivers and families,identi cation and appropriate management plan should be developed at primary health-care level.The discrepancies of the recommendation on the three prioritized areas in di erent guidelines are compared in this paper.All the related guidelines emphasize the important of anthropometric measurement and monitor of growth for primary care workers and suggest dietary and physical activity counselling for obese people.Almost all the guidelines provide recommendations on breastfeeding and continued feeding counselling from the aspect of improving the status of acute or chronic malnutrition.The setting condition should be carefully considered when taking the guidelines of di erent organizations and countries into application.

Latent tuberculosis infection in health-care workers in the government sector in Brunei Darussalam:A cross-sectional study

Objective:Health-care workers(HCWs)are known to be at high risk for occupational biological hazards,and this includes exposure to mycobacterium tuberculosis(TB)which can result in either active or latent TB infection(LTBI).This study aims to provide an overview of the incidence of LTBI among HCWs in Brunei Darussalam,to examine associated risk factors,and to evaluate LTBI treatment compliance.Materials and Methods:This is a retrospective cross-sectional study which was conducted using data from January 2018 to December 2021,on notified cases of LTBI in HCWs which identified 115 cases.Demographic data,underlying medical conditions,and compliance to treatment were assessed through reviews of their electronic health records.Results:The incidence of LBTI was 14.6/year/1000 HCWs.The incidence rate reached a high of 24.6/1000 in 2020,and majority of cases were in the older age groups.There was good treatment acceptance and compliance(82.6%),and this was observed to be significantly higher in females than males(P=0.02).Conclusion:This study showed an average incidence of LTBI of 14.6/1000 HCWs over 4 years and high LTBI treatment acceptance(82.6%)and compliance.Emphasis on infection prevention and control measures in health-care settings and actions to increase awareness of LTBI are crucial interventions toward reducing the burden of LTBI.

Self-reported ischemic heart disease: Prevalence, sociodemographics, health behavior, health-care utilization, and quality of life

The aim of this study was to present the prevalence of self-reported Ischemic Heart Disease (IHD) based on a national population-based survey and to characterize people with self-reported IHD with respect to health behavior, risk factors, health-care services utilization and health-related HRQoL;further to compare people with self-reported IHD to those with other chronic illness and people without chronic illness. Based on the Danish Health Interview Survey 2005 (SUSY), a sample of 10,983 persons aged 35 years or older was examined. Data was collected through personal interviews (response rate = 66.7%) and self-administered questionnaires (51.5%). The sample was divided into three mutual exclusive groups: IHD;other chronic illnesses;and no chronic illness. The prevalence of IHD was 5.6% (5.2 - 6.0). The disease was more common in men than women, and the average age was 67.5 years. People with self-reported IHD were characterized as having poorer health behaviors;more risk factors: 40% smokers, 21% sedentary lifestyle, 26% obese;higher utilization of the health-care services;and poorer HRQoL. When compared to people with other chronic diseases, people with IHD continued to show the same characteristics. The IHD group had more problems affecting their daily lives than the other two groups. The issues that affected the people with IHD have also been shown to increase the load on the health-care system. Therefore, it is important to the patients, health-care, and society that the prevalence of IHD is reduced and the burden of disease is made a priority.

Improved Scatter Search Algorithm for Multi-skilled Personnel Scheduling of Ship Block Painting

This paper focuses on the optimization method for multi-skilled painting personnel scheduling.The budget working time analysis is carried out considering the influence of operating area,difficulty of spraying area,multi-skilled workers,and worker’s efficiency,then a mathematical model is established to minimize the completion time. The constraints of task priority,paint preparation,pump management,and neighbor avoidance in the ship block painting production are considered. Based on this model,an improved scatter search(ISS)algorithm is designed,and the hybrid approximate dynamic programming(ADP)algorithm is used to improve search efficiency. In addition,the two solution combination methods of path-relinking and task sequence combination are used to enhance the search breadth and depth. The numerical experimental results show that ISS has a significant advantage in solving efficiency compared with the solver in small scale instances;Compared with the scatter search algorithm and genetic algorithm,ISS can stably improve the solution quality. Verified by the production example,ISS effectively shortens the total completion time of the production,which is suitable for scheduling problems in the actual painting production of the shipyard.

The study comparatively analysed the socioeconomic characteristics and digital literacy level of Agricultural Extension personnel (AEP) in Ebonyi and Imo States, South-East, Nigeria. The specific objectives were to describe the socioeconomic characteristics of agricultural extension personnel in Ebonyi and Imo States, and to ascertain the digital literacy level of AEP in the studied states. Purposive sampling technique was used to select 312 Agricultural Extension personnel (132 from Ebonyi State Agricultural Development Program and 180 from Imo State Agricultural Development Program) for the study. Data were collected through the use of validated and structured questionnaire, and administered through the help of well-trained enumerators. Data were analysed using simple descriptive statistical tools such as percentages mean score, standard deviation and weighted mean. Findings indicated that they were more male in the both States (55.3% and 57.8%) for Ebonyi and Imo State respectively and that the average age of AEP in Ebonyi and Imo States were 44.7 years and 49.2 years respectively. It was further revealed that the majority (77.3% and 82.8%) had B.Sc./HND as their highest academic qualifications, belonged to professional organisations (62.1% and 75%), and were earning an average monthly income of N58,798 and N62,648 for Ebonyi and Imo State respectively. Also, it was revealed that their mean years of service were 12.4 years and 13.4 years for Ebonyi and Imo State respectively. Almost all of them (87.9% and 95.0%) own a smartphone, had access to the internet (80.3% and 90.0%), but do not own a laptop/ipad (82.6% and 72.8%) for Ebon-yi and Imo State respectively. Results further revealed that Agricultural extension personnel in both Ebonyi and Imo State respectively had low digital literacy level ( = 2.41 and 2.32). The study concluded that AEP in Ebonyi and Imo State respectively had similar socioeconomic characteristics and low level of digital literacy. The study recommended that the management of ADPs in both Ebonyi and Imo State should ensure the training of AEP in digital skills to enhance their digital literacy level to enable them use digital technologies in their work.

Nocturnal sentry duty and cardiometabolic characteristics in armed forces personnel

BACKGROUND Sleep deprivation can lead to increased body weight and blood pressure(BP),but the latent effects of partial sleep deprivation related to required night sentry duties within a short-term period on cardiometabolic characteristic changes in military personnel are unclear.AIM To investigate the association between night sentry duty frequency in the past 3 months and cardiometabolic characteristics in armed forces personnel.METHODS A total of 867 armed forces personnel who were aged 18-39 years and did not take any antihypertensive medications in Taiwan in 2020 were included.The frequency of night sentry duty was self-reported via a questionnaire(average number of night sentry shifts per month for the past 3 months).Hemodynamic status was assessed via the resting BP and pulse rate(PR).Cardiometabolic risk factors were defined according to the International Diabetes Federation criteria.Multivariable linear regression analyses of the associations between night sentry duties and PR,BP,and other metabolic syndrome(MetS)marker levels were performed,with adjustments for age,sex,substance use,body mass index and aerobic fitness.Multiple logistic regression analysis was carried out to determine the associations between night sentry duties and the prevalence of each MetS feature.

Detection Algorithm of Laboratory Personnel Irregularities Based on Improved YOLOv7

Due to the complex environment of the university laboratory,personnel flow intensive,personnel irregular behavior is easy to cause security risks.Monitoring using mainstream detection algorithms suffers from low detection accuracy and slow speed.Therefore,the current management of personnel behavior mainly relies on institutional constraints,education and training,on-site supervision,etc.,which is time-consuming and ineffective.Given the above situation,this paper proposes an improved You Only Look Once version 7(YOLOv7)to achieve the purpose of quickly detecting irregular behaviors of laboratory personnel while ensuring high detection accuracy.First,to better capture the shape features of the target,deformable convolutional networks(DCN)is used in the backbone part of the model to replace the traditional convolution to improve the detection accuracy and speed.Second,to enhance the extraction of important features and suppress useless features,this paper proposes a new convolutional block attention module_efficient channel attention(CBAM_E)for embedding the neck network to improve the model’s ability to extract features from complex scenes.Finally,to reduce the influence of angle factor and bounding box regression accuracy,this paper proposes a newα-SCYLLA intersection over union(α-SIoU)instead of the complete intersection over union(CIoU),which improves the regression accuracy while increasing the convergence speed.Comparison experiments on public and homemade datasets show that the improved algorithm outperforms the original algorithm in all evaluation indexes,with an increase of 2.92%in the precision rate,4.14%in the recall rate,0.0356 in the weighted harmonic mean,3.60%in the mAP@0.5 value,and a reduction in the number of parameters and complexity.Compared with the mainstream algorithm,the improved algorithm has higher detection accuracy,faster convergence speed,and better actual recognition effect,indicating the effectiveness of the improved algorithm in this paper and its potential for practical application in laboratory scenarios.

通风方式对非对称隧道火灾烟气蔓延的影响

为研究非对称隧道内不同通风方式对火灾烟气蔓延的影响,利用PyroSim数值模拟软件构建非对称隧道模型,对隧道内烟气流速、温度分布和烟气运动进行研究,并分析了不同风速对人员疏散的影响。结果表明:上坡隧道内诱导气流与补充气流存在竞争关系,随着坡度差增大,烟气流速增加,烟气从上坡隧道排出,新鲜空气从平坡段隧道进入补充燃烧消耗;自然通风下隧道充满烟气,在纵向风速1.5 m/s下隧道环境得以改善;随着风速继续增大,隧道烟气流速紊乱,烟气层被扰乱。在实际非对称隧道中,建议火灾初期以1.5 m/s的纵向风速进行通风,待人员疏散后再增加风速加速排烟。
