Background Test consolidation and total laboratory automation (TLA) were implemented in a core laboratory with a high volume of specimens in a medical center in Taiwan to reduce the costs of laboratory services and improve laboratory workflow and performance. Methods Using a retrospective research approach, 5 stat and 7 routine tests were used to analyze the in-laboratory to report turnaround time (IR-TAT). Mean, SD, medium, 90th percentile, outlier percentage of IR-TAT, full-time equivalents, productivity, tube touch moment (TTM), and financial impact were determined and compared pre- and post-TLA. Results The mean IR-TAT of overall stat chemical tests for inpatient and outpatient were 32.8% and 11.9% reductions, respectively. The productivity of each medical technologist increased by 32.4% per month, and there was a reduction of 5 medical technologists compared with the number required to complete the same tests before consolidation. The TTM of staff per year post-TLA decreased by 74.1% tube touches. Conclusion The efficiency of laboratory services was improved by consolidation to the core laboratory along with TLA implementation coupled with logic rules such as delta-check and autoverification. Effectiveness was improved as measured by an increase in productivity, labor reduction, staff safety, and cost reduction. [ABSTRACT FROM AUTHOR]

Background Medical laboratory staffing shortages have persisted, with challenges in maintaining adequate medical laboratory professionals. The career trajectory for medical laboratory scientists beyond entry level is ambiguous, but advancement opportunities are enhanced with specialist certifications and advanced degrees. Objective This study explored the motivation and preferences of medical laboratory scientists in pursuing graduate medical laboratory science education based on the importance of professional development, career advancement, recognition, and employment benefits. Methods A quantitative, cross-sectional, and descriptive correlational study surveyed American Society for Clinical Pathology Board of Certification−credentialed medical laboratory scientists using an online questionnaire. Results The overall response rate was 2.5%, and 1247 complete surveys were analyzed. Educational preferences varied by respondent age and amount of laboratory experience. Professional development, career advancement, recognition, and employment benefits were all important motivators for seeking graduate degrees, but those who were younger and had less experience indicated they were more important. Conclusion This study suggests several areas of improvement for educational programs, health care organizations, and professional organizations to support the motivation of medical laboratory scientists to pursue graduate education.

This study identify the prevalence of sharp object injuries (SOIs) among healthcare workers (HCWs) in Dammam and Jeddah, Saudi Arabia. Methods: Quantitative methodology using a cross-sectional design was applied. Chi-square testing was employed for comparative analyses, and logistic regression encompassing univariate and multivariate models was implemented to ascertain the predictors of SOIs. Results: Prevalence rate of SOIs among hospital HCWs in Dammam and Jeddah cities was 8.40%. Non-Saudi nationals had a rate of 11.9%, while participants who had more than 15 years of experience had a lower rate (9.9%). Gender was identified as a significant predictor of SOIs, with males being two times more likely to experience SOIs than females. The highest rates of injuries were observed among laboratory personnel (29.2%; odds ratios of 8.6 and 7.2 in univariate and multivariate models, respectively). Conclusion: These findings show that HCWs in Dammam have a marginally higher risk of SOIs (prevalence rate 9%) than their counterparts in Jeddah (prevalence rate 7.8%). Further investigations are needed to tailor specific training programs to increase HCWs' awareness, safety knowledge, and practices to reduce SOIs. [ABSTRACT FROM AUTHOR]

ABSTRACT There have been considerable advances in diagnosing and treating bleeding disorders. But the scenario remains dismal in resource‐constrained settings in low and lower‐middle‐income countries (LMICs). Seventy‐five percent of the patients with inherited bleeding disorders do not get diagnosed in LMICs. In resource‐constrained settings, infectious disease and malignancies take the major focus. Bleeding disorders do not get prioritised in LMICs, and this leads to underdiagnoses and suboptimal treatment. There are various challenges like financial status, inadequacy of health care infrastructure, lack of patient registry and lack of awareness across medical staff, general population and government stakeholders. The lack of skilled laboratory personnel and laboratory infrastructure for optimal bleeding disorder diagnosis adds on to the problem. World Federation of Hemophilia (WFH) has been at the forefront in developing strategies to overcome some of these inadequacies; however, more active participation of the stakeholders including patients, medical professionals and policy makers is the need of the hour. This review highlights the different challenges in LMICs in diagnosing bleeding disorders, the gap between high‐income countries and LMICs and the possible strategies in closing the gap.

Background: Pathology services represent an ideal setting to integrate absolute cardiovascular disease (CVD) risk estimation when patients attend for routine cholesterol testing. This study aimed to explore the process of implementing CVD risk estimation into point‐of‐care service delivery by pathology staff to inform future implementation and sustainability. Methods: A new service for CVD risk estimation via a self‐directed screening station was implemented into 14 pathology service sites across Tasmania, Australia. Before implementation, observations at pathology services (n = 26) and semi‐structured interviews were undertaken with 26 pathology staff (88% female, 77% aged 41–60 years) to identify factors that could impact implementation of the service. The process of implementation was then evaluated using participant observations and clinical trial recruitment data. Transcripts and field notes were analysed thematically according to the Medical Research Council Framework and used to develop a programme logic model to understand how the service could be adapted to be successfully integrated into routine workflow at pathology services. Results: Eight key themes were identified during the pre‐implementation phase as important factors that could impact upon integration of CVD risk estimation into pathology services. Themes related to factors within the organisation, including available resources, logistics and workflow, as well as having sufficient time to complete the intervention. Additional factors related to the individual motivations of staff, collaborative leadership and patient characteristics. Success of implementation varied among sites, requiring the trialling of different strategies to support uptake of the service and patient recruitment. Conclusions: Implementing CVD risk estimation into point‐of‐care pathology services required an understanding of the core implementation components specific to each context, and for implementation strategies to be targeted to the individual and organisational contexts. The generated programme logic model may be useful in guiding future implementation endeavours within these services and aiding the selection of apt implementation strategies.

The list of standard abbreviations for JDS is available at adsa.org/jds-abbreviations-24. Nonstandard abbreviations are available in the Notes. To comply with antibiotic restriction policies in the European Union, internal teat sealants (TS) are increasingly used at dry off (DO) in selective dry cow treatment protocols to maintain udder health. Postcalving TS residue attachment to milking equipment and associated cleaning difficulties is a reason some farmers stay away from blanket TS use. Our objective was therefore to improve insight into TS excretion visibility and to compare quantity, pattern, and presence versus absence of TS excretion postcalving between the typical 2 cow categories at DO: high (H)- and low (L)-SCC cows, treated with antibiotic (AB) plus TS (H-ABTS) or TS only (L-TS), respectively. In herds in the Netherlands (n = 3), and Germany (n = 4), cows were enrolled at DO, and categorized as H-ABTS (n = 93), or L-TS (n = 99). Postcalving, quarter-level TS visibility, quantities, patterns, and percentage of TS infused and excreted postcalving were recorded from 50 mL of premilk of every quarter at each of the first 15 or 16 milkings. Udder quarter health status was determined by bacteriological culture and SCC of quarter milk samples taken at DO and at d 3 postcalving and by clinical mastitis incidence from DO until 30 DIM. Univariable and multivariable models were created to explore associations of TS excretion presence versus absence at the first 3 milkings. Irrespective of SCC category, both laboratory personnel and farmers saw TS residues at the first milking in an equal 72% of quarters. Compared with laboratory as the gold standard, farmer sensitivity to spotting TS in premilk was 74.5% at the first milking and decreased to a maximum of 8.3% at the last 3 milkings. At the first milking, TS excretion quantities showed a bimodal distribution pattern and the mean percentage of TS infused (3.83 g) that was excreted in premilk at the first milking, was higher in the L-TS cows (45.5%) compared with the H-ABTS cows (32%). At the second and third milking, mean-adjusted TS percentage excreted was higher in the H-ABTS cows (8.5% and 1.8%, respectively) compared with the L-TS cows (4.6% and 0.4%, respectively). The multivariable model of the first 3 milkings showed parity at both the first and second milking, and the study group at both the second and third milking was significantly associated with TS presence. The univariable model showed no association between TS presence at the first milking and udder health. In conclusion, in premilk of the first milking, TS residue excretion was bimodal, higher in L-TS cows, more likely to be present in multiparous cows, and not associated with udder health. At the second and third milking, excretion was higher in H-ABTS cows and TS presence was only more likely in multiparous cows at the second milking. [ABSTRACT FROM AUTHOR]

Vaccination has saved millions of lives and is regarded as one of modern medicine’s most important successes. Effective vaccination programs should be based on risk assessment that considers demographic and occupational factors. When developing a vaccination program, it is essential to identify the target groups, including travelers, infants, high-risk workers, and those in critical roles such as farming and agriculture. In biosafety and biosecurity, vaccines are a key component of measures designed to protect laboratory personnel, the community, and the environment. Guidelines from global health organizations such as the Centers for Disease Control and Prevention are tailored to specific pathogens and depend on the type of work performed and the associated risk. These guidelines are continuously revised and updated to ensure the effectiveness of vaccination programs. Vaccines also play a role in One Health approaches that are focused on the interconnectedness of animals, humans, and the environment. Targeted vaccination strategies for both domestic animals and wildlife are necessary to maintain animal health, improve livestock productivity, and prevent the spread of zoonotic and foodborne diseases to humans. In this paper, we aimed to provide an overview regarding the crucial roles of vaccines in biosafety, biosecurity, and One Health approaches, as well as to highlight the importance of targeted and personalized strategies to improve the effectiveness of vaccination programs. Herein, we also discuss various vaccines aimed at specific target groups as recommended by global health organizations, with a particular emphasis on laboratory workers and the vaccines necessary to reduce laboratory-acquired infections. Finally, we discuss animal vaccines and targeted strategies for vaccinating domestic and wildlife populations.

Academic chemical laboratories (ACL) are considered public places the employees come in contact with a variety of pollutants. The aim of the current study was to detect heavy metals levels in the indoor air of ACL in two universities in Baghdad city and assess their levels in the academic employees’ scalp hair as biomarkers. Air samples inside ACL were collected to detect Fe, Cd, Zn, Pb and Cu. Scalp hair samples were collected from 40 adult chemical laboratory employees aged 30-60 years, who worked 5 days/week for 6 hours a day. Personal information relating to employees such as age, duration of exposure, smoking habit and sex, was collected as a questionnaire. The results of this study concluded that academic laboratory employees were exposed to high levels of heavy metals which was proven through the use of scalp hair; old ages, prolonged working periods, smoking habit have significant effects in increasing the levels of heavy metals in scalp hair, while the employees’ gender variation did not have a significant effect.

Histotechnology educational programs are accredited by the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS) and currently number fewer than 50 in the United States which contributes to the shortages of laboratory personnel. A survey tool designed with REDCap software was distributed to all programs identified on the NAACLS website and consisted of three parts: a) program information, b) facility information, and c) challenges. Programs are located primarily in large urban centers where populations are most concentrated. The median class size was 6 which may explain the excellent student outcomes to include 96% graduation rates and 90.7% board of registry examination pass rates. Overall, programs had ample equipment, funding, and administrative support. Costs to attend the programs were relatively low (<$3,000 per semester) for over half of the programs. However, due to the small number of accredited education programs across the US, potential students do not often have access to an institution in their area. The programs indicated that the most common challenge was recruitment of adequate high-quality candidates which may explain, in part, the persistent shortage of personnel in the histology laboratory.

The role of Laboratory Medicine in patient care has evolved in the last decades. The same has occurred to the laboratory model, which has evolved from a traditional model where the laboratory is merely involved in clinical decision-making to a leading model where the laboratory is not only involved but also determines decision-making. The advent of new technologies and automation of processes have enabled laboratory professionals to focus on the first and last phase of the analytical process namely, test ordering and decision-making based on laboratory results. These phases are more error-prone than the analytical phase, and where action must be taken to improve the quality of patient care. We share our experience in the design and establishment of laboratory test demand management interventions that facilitated diagnosis of occult disease, improved adherence to clinical guidelines, and optimized patient safety. A description is provided of key points in the management of laboratory test over/underutilization. The objective of this review is to promote the involvement of laboratory professionals in the design and implementation of demand management interventions and in the development of the new Leader Laboratory model.

Inadequate risk assessment and a lack of risk monitoring are common deficiencies in clinical laboratory, and are also the main causes of biosafety incidents. Therefore, we summarized the experience of implementing adequate risk assessment and maintaining risk monitoring, and established a procedure for continuously improving biosafety management. Methods: Learning from our laboratory's experience in implementing risk assessment, risk response, and risk monitoring before and during the COVID-19 epidemic, we summarized the procedures for fully identifying risks, accurately evaluating risks, maintaining risk monitoring, establishing and regular reviewing safety indicators. On this basis, we established a system for continuously improving biosafety management through risk monitoring and reviewing safety indicator. Results: We identified a total of 30 unacceptable risks prior to the COVID-19 pandemic, and developed and implemented appropriate risk control measures. After risk control, residual risks were acceptable, and no biosafety incidents have occurred. During the COVID-19 pandemic, after multiple risk monitoring, we identified ten new risks, three ineffective risk control measures, and multiple control measures for excessive protection. Then, we timely adjusted risk control measures to avoid laboratory personnel infection and excessive protection. Meanwhile, We established eight safety indicators and identified two improvement opportunities through regular reviews. Conclusion: Adequate risk identification and accurate risk assessment are particularly important for effectively controlling biosafety risks. Biosafety management should be continuously improved to deal with ineffective and excessive protection caused by various changes in experimental activities. Continuous improvement of biosafety management can be achieved through risk monitoring, regular review of safety indicators, and management reviews. This study will help laboratory managers to fully and accurately assess risks, as well as update risks and their control measures through risk monitoring, and the continuous improvement procedure established in the study has certain reference value for laboratories to effectively respond to emerging infectious diseases and avoid excessive protection.

Background: The realm of medical laboratory technology (MLT) training and education is unstructured in Pakistan. The primary challenge currently confronting the workforce in MLT is the absence of standardized curricula and assessments in education and training. This was an exploratory study aiming to inquire experiences of trainees, alumni and teaching coordinators regarding the technologist training program in a single institute at Pakistan. Methods: To gain an in depth understanding of MLT program, three focus group discussions (FGDs) were held at Department of Pathology and Laboratory Medicine, Aga Khan University, Pakistan during Feb-April 2024. A team of pathologists and educationists developed interview guides for FGDs in English. Interviews were bilingual, transcribed verbatim and coded using thematic analysis. Participants included current trainees, alumni, teaching and learning coordinators and moderators for the interview. Results: A total of 29 participants were engaged; these included current MLT trainees (n = 10), alumni (n = 10), and teaching/learning coordinators and sectional supervisors (n = 9). Five main themes emerged from the analysis of FGDs: (Scott MG, Rifai N, Smith B, Oellerich M, Panteghini M, Apple F et al.

In this second episode of the Microbiologist in the Clinic series, clinicians and laboratory scientists share their perspectives about a 75-year-old woman who was diagnosed with asymptomatic bacteriuria based on positive urine cultures. The patient and her GP are concerned about this laboratory finding as the patient will become immunosuppressed with planned chemotherapy. The patient has had an overactive bladder (OAB) for approximately 20 years, with good control of her urinary urgency and frequency (no incontinence) with a stable dose of OAB medication. The challenges of this clinical presentation are discussed, with evidence for evaluation and treatment. [ABSTRACT FROM AUTHOR]

Objective To understand the current status of occupational stress among biosafety laboratory (BSL) staff in Xinjiang and to analyze its possible influencing factors and its association with work -related musculoskeletal disorders (WMSDs). Methods A cluster sampling method was used to survey BSL staff across various regions in Xinjiang in May Musculoskeletal Disorders Questionnaire was used to assess WMSDs. Multivariate logistic regression was used to analyze the influencing factors of occupational stress. Propensity score matching was used to match demographic variables and work - related factors of employees with and without WMSDs, followed by multivariate logistic regression to analyze the association of occupational stress and the risk of WMSDs in BSL staff. Results A total of 7 924 staff were included in the study, with an occupational stress detection rate of 83.38% (6 607 individuals) and a WMSDs detection rate of 69.16% (5 480 individuals). The results of the multivariate logistic regression analysis revealed that the occupational stress of laboratory personnel working in BSL-2 facilities was 1.219 times (P < 0.05) higher than that in BSL-1 facilities. The staff in the 30 to 44 age group and the ≥ 50 age group exhibited 1.221 -fold and 1.375 -fold (both P < 0.05) higher risks of occupational stress, respectively, compared to the staff in the 20 to 25 age group. Laboratory workers with associate degrees and bachelor's degrees or higher had 1.527-fold and 2.379-fold (both P < 0.05) increased risks of occupational stress, respectively, compared to those with vocational education or below. Management personnel and laboratory technicians showed 1.772 -fold and 1.840 -fold (both P < 0.05) higher risks of occupational stress, respectively, compared to other positions (e.g., logistics staff, engineers). Laboratory personnel with monthly incomes ≥ 4 000 yuan had a 1.374 -fold increased risk of occupational stress compared to those earning < 4 000 yuan (P < 0.05). Propensity score matching analysis indicated that before matching, most variables differed statistically significantly (P < 0.05) between the two groups of employees (with and without WMSDs). After matching, 2 223 pairs of BSL staff were obtained, with no statistically significant differences (all P > 0.05) between the groups in all demographic and work-related variables (gender, BSL level, age, education level, years of work experience, professional title, job category, marital status, and monthly income). Postmatching multivariate logistic regression analysis demonstrated that the risk of musculoskeletal disorders was positively related to the effort, reward, and overcommitment dimensions of the ERI scale among BSL staff (OR = 1.06, 1.01, and 1.06, all P < 0.001), respectively. Conclusions Occupational stress and musculoskeletal disorders were prevalent among BSL staff, with occupational stress potentially increasing the risk of WMSDs. It is suggested that work tasks should be allocated reasonably based on individual capabilities, standardized work processes should be established, regular health education should be conducted, and timely psychological counseling and guidance should be provided to actively prevent psychological issues among BSL staff.

Introduction: Blood culture is the gold standard for diagnosing bacteremia and direct the physicians to select appropriate antimicrobials. In hospitals, blood culture contamination (BCC) is a common problem that has a detrimental effect on patient outcomes. Hence, we implemented strategies in our tertiary care setup, for training phlebotomists and nurses in proper blood sampling techniques, and assessed their effectiveness in reducing BCC rates. Methods: This interventional study was conducted at the Indus Hospital, Karachi, Pakistan from 1st January 2021 to 30th June 2023. All blood cultures received from different departments of the hospital were included. The 2.5-year study period was divided into pre-intervention and intervention periods, with monthly monitoring of BCC. The BCC data between 1st January 2021 and 31st December 2021 was taken as the baseline pre-intervention period and the next 1.5 years comprised the intervention period (1st January 2022-30th June 2023). To improve compliance, various strategies were implemented, such as regular training sessions, didactic sessions, and re-competencies. Results: A total of 86 774 Blood cultures were received from all departments of the hospital, out of which n = 30 672 were received in the pre-intervention period whereas, n = 56 102 were received in the intervention period. Mean BCC rate in the pre-intervention period was found to be 4.6%. However, after the implementation of different measures to reduce BCC, the contamination rate decreased to a mean of 3.1% by the end of the intervention period. Emergency department accounted for the highest proportion of BCC in the pre-intervention and intervention periods. Conclusion: We decreased BCC in our tertiary care setup by implementing a simple and inexpensive collaborative intervention, and came to the conclusion that the higher incidence of BCC was probably caused by factors unique to the emergency department and provided measures to successfully address them.

Background: Chronic infection with Schistosoma haematobium causes female genital schistosomiasis (FGS), which leads to diverse lesions in the female genital tract and several complications, including infertility and a higher risk for HIV transmission. This study aims to understand the knowledge, attitudes, and practices (KAP) toward FGS and associated factors among women and health professionals in the schistosomiasis endemic focus of Kimpese, western Democratic Republic of Congo (DRC). Methods: In January 2022, two semi-quantitative questionnaires were administered to 201 randomly selected community women in Kifua II village, and to purposely selected health professionals (20 nurses and 41 doctors) from Kimpese Health Zone. KAP statements were coded using Likert scale, summarized as frequencies and percentages, and assessed for internal reliability using Cronbach's alpha. Associations between the socio-demographic characteristics of respondents and the KAP variables were assessed using Pearson chi-square (χ2) test, Cramer's V (φ) and gamma (γ) coefficients. Results: Overall, respondents had high knowledge of schistosomiasis in general but low FGS-specific knowledge (91% versus 45%). Misconceptions concerned the disease transmission, with 30.3% of women and 25% of the nurses believing that FGS is transmitted by drinking untreated water, while 26.8% of the doctors mentioned sexual contact as a mode of FGS transmission. Negative attitudes included considering FGS not a very serious disease (34.8%), feeling uncomfortable during gynaecological examination (35.3%), difficulties avoiding risky water contact (72.1%) and open defecation/urination (41.3%), not intending to share FGS status with their husbands (38.3%) and loved ones (63.6%), and believing that husbands would leave them if they were infertile (31.8%). Regarding practices, 77.6% of women engaged daily in activities involving contact with water. Practices of health professionals were hampered by the lack of equipment and specialized knowledge for FGS diagnosis with only 57% of healthcare workers having a microscope in their facilities. Women's KAPs varied by age, education, marital status, occupation and monthly income. Conclusion: This study highlights insufficient knowledge, existing negative attitudes, at risk practices towards FGS by women, and limitations of FGS management by health professionals. These findings can help for tailored health education and WASH strategies, and call for health professional's capacities reinforcement. Author summary: Schistosomiasis is a disease caused by parasitic worms and it is contracted through contact with contaminated water. FGS is a long-term consequence of urogenital schistosomiasis, a form of the disease that affects the female reproductive organs and can lead to infertility, but also stigma and discrimination. This study used a quantitative research approach to explore community women and healthcare workers' knowledge, attitudes and practices on and health-seeking behaviour of the women regarding FGS in Kongo Central, DRC. While both groups had high knowledge of schistosomiasis, they had a limited understanding of FGS specifically. Misconceptions about its cause and prevention were common, particularly among medical doctors. Many community members engaged in risky water contact and hygiene practices. Healthcare workers reported limited diagnostic tools and expressed interest in specialised training on FGS diagnosis, treatment, and prevention. Consequent to limited knowledge and ill-equipped laboratories, health workers are most likely underreporting the disease in the region. The study highlights the need to integrate FGS into public health education programs for both community members and healthcare workers in Kongo Central and underscores the importance of addressing misconceptions about the disease and the prevention measures.

Background: The precision of test measurements is critical in clinical diagnostics, especially for biomarkers like total PSA and homocysteine, which are essential to disease assessment. Using the CMIA approach, this study investigates the repeatability and reproducibility of these biomarkers on the Abbott Alinity system. Methods: The present study was conducted in the clinical chemistry laboratory at Mohammed VI University Hospital of Oujda. The evaluation of the Alinity i-system’s analytical performance for total PSA and homocysteine focused on assessing repeatability and intermediate precision. The assessment followed the protocols and guidelines established by the French Accreditation Committee (COFRAC). Results: Our analysis yielded favorable findings regarding the performance of the Alinity assays. The coefficients of variation for both the within-run and between-run precision were less than 5.89% and 4.29%, respectively. These findings produce acceptable outcomes compared to the manufacturer’s claims and the SFBC database. Our study underscores the tests’ precision, affirming the CMIA method’s reliability in measuring total PSA and homocysteine levels. Conclusions: The assessment of the Alinity i-system for total PSA and homocysteine showed significant analytical performance. Our findings have implications for laboratory personnel, researchers, and physicians supporting a continuous diagnostic accuracy improvement culture. [ABSTRACT FROM AUTHOR]

A human hookworm vaccine is being developed to protect children against iron deficiency and anaemia associated with chronic infection with hookworms. Necator americanus aspartic protease-1 (Na -APR-1) and N americanus glutathione S-transferase-1 (Na -GST-1) are components of the blood digestion pathway critical to hookworm survival in the host. Recombinant Na -GST-1 and catalytically inactive Na -APR-1 (Na -APR-1[M74]) adsorbed to Alhydrogel were safe and immunogenic when delivered separately or co-administered to adults in phase 1 trials in non-endemic and endemic areas. We aimed to investigate the safety and immunogenicity of these antigens in healthy children in a hookworm-endemic area. This was a randomised, controlled, observer-blind, phase 1, dose-escalation trial, conducted in a clinical research centre, in 60 children aged six to ten years in Lambaréné, a hookworm-endemic region of Gabon. Healthy children (determined by clinical examination and safety laboratory testing) were randomised 4:1 to receive co-administered Na -GST-1 on Alhydrogel plus Na -APR-1(M74) on Alhydrogel and glucopyranosyl lipid A in aqueous formulation (GLA-AF), or co-administered ENGERIX-B hepatitis B vaccine (HBV) and saline placebo, injected into the deltoid of each arm. Allocation to vaccine groups was observer-masked. In each vaccine group, children were randomised 1:1 to receive intramuscular injections into each deltoid on two vaccine schedules, one at months 0, 2, and 4 or at months 0, 2, and 6. 10 μg, 30 μg, and 100 μg of each antigen were administered in the first, second, and third cohorts, respectively. The intention-to-treat population was used for safety analyses; while for immunogenicity analyses, the per-protocol population was used (children who received all scheduled vaccinations). The primary outcome was to evaluate the vaccines' safety and reactogenicity in healthy children aged between six and ten years. The secondary outcome was to measure antigen-specific serum IgG antibody levels at pre-vaccination and post-vaccination timepoints by qualified ELISAs. The trial is registered with ClinicalTrials.gov , NCT02839161 , and is completed. Between Jan 23 and Oct 3, 2017, 137 children were screened, of whom 76 were eligible for this trial. 60 children were recruited, and allocated to either 10 μg of the co-administered antigens (n=8 for each injection schedule), 30 μg (n=8 for each schedule), 100 μg (n=8 for each schedule), or HBV and placebo (n=6 for each schedule) in three sequential cohorts. Co-administration of the vaccines was well tolerated; the most frequent solicited adverse events were mild-to-moderate injection-site pain, observed in up to 12 (75%) of 16 participants per vaccine group, and mild headache (12 [25%] of 48) and fever (11 [23%] of 48). No vaccine-related serious adverse events were observed. Significant anti- Na -APR-1(M74) and anti- Na -GST-1 IgG levels were induced in a dose-dependent manner, with peaks seen 14 days after the third vaccinations, regardless of dose (for Na -APR-1[M74], geometric mean levels [GML]=2295·97 arbitrary units [AU] and 726·89 AU, while for Na -GST-1, GMLs=331·2 AU and 21·4 AU for the month 0, 2, and 6 and month 0, 2, and 4 schedules, respectively). The month 0, 2, and 6 schedule induced significantly higher IgG responses to both antigens (p=0·01 and p=0·04 for Na -APR-1[M74] and Na -GST-1, respectively). Co-administration of recombinant Na -APR-1(M74) and Na -GST-1 to school-aged Gabonese children was well tolerated and induced significant IgG responses. These results justify further evaluation of this antigen combination in proof-of-concept controlled-infection and efficacy studies in hookworm-endemic areas.

Background: CK-MB is a subtype of creatine kinase isoenzyme, mainly present in myocardial tissue. When myocardial tissue damage is severe, CK-MB is released into the blood, and the serum level significantly increases, which is an important indicator for diagnosing acute myocardial infarction. Methods: We reported a case of pseudo-elevation of CK-MB without acute myocardial infarction. Results: The immunosuppressive assay showed that the activity of CK-MB isoenzyme was 903.0 U/L, which was significantly increased. The patient underwent examinations such as cardiac ultrasound and coronary artery imaging, and no obvious abnormalities were found. Suspected interference, CK-MB was measured using mass immunoassay, and the result was 1.96 ng/mL, which is within the normal range. Conclusions: When the CK-MB level (immunosuppressive assay) abnormally increases but clinical examination does not support the diagnosis of acute myocardial infarction, laboratory personnel should be aware of the shortcomings of this method and use mass immunoassay to detect CK-MB to eliminate interference, and avoid unnecessary examinations and treatments for patients due to inaccurate results.

Background: Biomechanical changes and neuromuscular adaptations have been suggested as risk factors of secondary injury in individuals after anterior cruciate ligament reconstruction (ACLr). To achieve a better understanding of preventive mechanisms, movement quality is an important factor of consideration. Few studies have explored time-series analysis during landing alongside clinical performance in injured and non-injured individuals. The purpose of the study was to investigate the biomechanical risks of recurrent injury by comparing clinical and jump-landing performance assessments between athletes with ACLr and healthy controls. Method: This study was observational study. Sixteen athletes with and without ACLr voluntarily participated in clinical and laboratory measurements. Single-leg hop distance, isokinetic tests, landing error score, and limb symmetry index (LSI) were included in clinical report. Lower limb movements were recorded to measure joint biomechanics during multi-directional landings in motion analysis laboratory. Hip-knee angle and angular velocity were explored using discrete time-point analysis, and a two-way mixed analysis of variance (2 × 4, group × jump-landing direction) was used for statistical analysis. Time series and hip-knee coordination analyses were performed using statistical parametric mapping and descriptive techniques. Results: Significantly lower single-leg hop distance was noted in ACLr group (158.10 cm) compared to control group (178.38 cm). Although the hip and knee moments showed significant differences between four directions (p < 0.01), no group effect was observed (p > 0.05). Statistical parametric mapping showed significant differences (p ≤ 0.05) between groups for hip abduction and coordinate plot of hip and knee joints. Athletes with ACLr demonstrated a higher velocity of hip adduction. Time-series analysis revealed differences in coordination between groups for frontal hip and knee motion. Conclusions: Athletes with ACLr landed with poor hip adduction control and stiffer knee on the involved side. Multi-directions landing should be considered over the entire time series, which may facilitate improved movement quality and return to sports in athletes with ACLr. [ABSTRACT FROM AUTHOR]

Introduction: Ironman triathletes undergo high workloads during competition preparation which can result in nonfunctional overreaching or overtraining syndrome if not matched with adequate recovery. Purpose: The purpose of this case study was to observe changes in physiological and psychological status over the course of a competitive season in a free-living triathlete. Methods: The subject was a 41-year-old triathlete competing in three 113.1-km events. Over the course of a 40-week period, the participant arrived at the laboratory every 4 weeks and underwent body composition testing via air displacement plethysmography, a blood draw for analysis of various biomarkers, and a treadmill-based lactate threshold test. Workload during training and competitions was monitored via a wearable heart rate-monitoring device. Results: Throughout the season, training volume remained high (12.5 ± 3.4 h/week) and body mass and fat-free mass (FFM) continuously decreased, while biomarkers including cortisol, testosterone, and markers of immunological status exhibited minor changes. Laboratory performance remained relatively consistent, while competition performance continually improved. Following the completion of the competitive period, training volume decreased, FFM remained below baseline levels, free cortisol increased, and both free and total testosterone decreased. Conclusions: Workload and recovery seem to have been properly managed throughout the season, evidenced by minimal fluctuations in endocrine and immunological markers. The reason for changes observed in testosterone, cortisol, and body composition following the last competition is unclear, though it may be attributed to changes in stressors and recovery practices outside of training. It is recommended that athletes follow a structured plan during the transition period into the offseason to ensure recovery of physiological state and to set up a productive offseason.

Numerous hospital laboratories in Indonesia need to implement improved bio-risk management (BRM) systems. There are many potential biohazards in laboratory activities that can impact health and the environment, leading to laboratory incidents. To minimize the impact and occurrence of such incidents, it is necessary to evaluate the implementation of BRM in every hospital laboratory that uses biological agents. This study was conducted in eight COVID-19 reference hospitals in Indonesia in the regions of Sumatra, Kalimantan, and Java, which have committed to implementing BRM systems in their laboratory activities. This research employed a descriptive study design and quantitative methods, with the aim of analyzing and evaluating the implementation of BRM systems in laboratories by assessing the achievements and gap analysis obtained from each laboratory. This research utilized primary data in the form of checklist forms referencing ISO 35001:2019 for the laboratory BRM system. Then, the assessments were based on virtual interviews conducted by the researcher with laboratory personnel as the primary data. The evaluation conducted on gap analysis from the seven clauses in ISO 35001:2019 across all hospitals revealed large gaps, particularly in three clauses: leadership, support, and performance. However, the aspects concerning organization, improvement, and performance evaluation were relatively satisfactory. Hence, there is a need for further improvement in leadership, support, and performance evaluation clauses. Additionally, it is essential to highlight the importance of comprehensive performance assessment, including proactive audits and continuous enhancements to achieve optimal bio-risk management.

Background: Nonadherence to national standards for malaria diagnosis and treatment has been reported in Sudan. In this study, qualitative research examined the clinical domains of nonadherence, factors influencing nonadherent practices and health workers' views on how to improve adherence. Methods: In September 2023, five Focus Group Discussions (FGDs) were undertaken with 104 health workers from 42 health facilities in Sudan's Northern State. The participants included medical assistants, doctors, nurses, laboratory personnel, pharmacists and public health officers. The FGDs followed a semi-structured guide reflecting the national malaria case management protocol. Qualitative thematic analysis was performed. Results: Nonadherent practices included disregarding parasitological test results, suboptimal paediatric artemether–lumefantrine (AL) dosing, lack of counselling, use of prohibited artemether injections for uncomplicated and severe malaria, artesunate dose approximations and suboptimal preparations, lack of AL follow on treatment for severe malaria; and rare use of primaquine for radical Plasmodium vivax treatment and dihydroartemisinin-piperaquine as the second-line treatment for uncomplicated malaria. Factors influencing nonadherence included stock-outs of anti-malarials and RDTs; staff shortages; lack of training, job aids and supervision; malpractice by specialists; distrust of malaria microscopy and RDTs; and patient pressure for diagnosis and treatment. Health workers recommended strengthening the supply chain; hiring personnel; providing in-service protocol training including specialists; establishing external quality assurance for malaria diagnosis; and providing onsite supportive supervision and public health campaigns. Conclusions: This study revealed a broad spectrum of behavioural and systemic challenges in malaria management among frontline health workers in Northern Sudan, including nonadherence to protocols due to resource shortages, training gaps, a lack of supportive supervision and patient pressure. These insights, including health workers' views about improvements, will inform evidence-based interventions by Sudan's National Malaria Control Programme to improve health systems readiness and the quality of malaria case management.

Objectives: The objective of this study was to collect information on human chorionic gonadotrophin (hCG) laboratory testing and reporting in women with gestational trophoblastic disease (GTD), to assess the associated challenges, and to offer perspectives on hCG testing harmonisation. Design: Information was collected from laboratories by electronic survey (SurveyMonkey) using a questionnaire designed by members of the European Organisation for the Treatment of Trophoblastic Disease (EOTTD) hCG working party. Participants: The questionnaire was distributed by the EOTTD board to member laboratories and their associated scientists who work within the GTD field. Setting: The questionnaire was distributed and accessed via an online platform. Methods: The questionnaire consisted of 5 main sections. These included methods used for hCG testing, quality procedures, reporting of results, laboratory operational aspects, and non-GTD testing capability. In addition to reporting these survey results, examples of case scenarios which illustrate the difficulties faced by laboratories providing hCG measurement for GTD patient management were described. The benefits and challenges of using centralised versus non-centralised hCG testing were discussed alongside the utilisation of regression curves for management of GTD patients. Results: Information from the survey was collated and presented for each section and showed huge variability in responses across laboratories even for those using the same hCG testing platforms. An educational example was presented, highlighting the consequence of using inappropriate hCG assays on clinical patient management (Educational Example A), along with an example of biotin interference (Educational Example B) and an example of high-dose hook effect (Educational Example C), demonstrating the importance of knowing the limitations of hCG tests. The merits of centralised versus non-centralised hCG testing and use of hCG regression curves to aid patient management were discussed. Limitations: To ensure the survey was completed by laboratories providing hCG testing for GTD management, the questionnaire was distributed by the EOTTD board. It was assumed the EOTTD board held the correct laboratory contact, and that the questionnaire was completed by a scientist with in-depth knowledge of laboratory procedures. Conclusions: The hCG survey highlighted a lack of harmonisation of hCG testing across laboratories. Healthcare professionals involved in the management of women with GTD should be aware of this limitation. Further work is needed to ensure an appropriate, quality-assured laboratory service is available for hCG monitoring in women with GTD. [ABSTRACT FROM AUTHOR]

"Artificial intelligence" is a term expressing the ability of a machine to simulate human intelligence. AI is rapidly and massively entering various professional fields, including education and healthcare. We present a small-scale study conducted with two groups of students - 10 from the "X-ray laboratory assistant" speciality and 6 from the "Midwife" speciality at Medical University Plovdiv. The aim is to reveal the extent and reasons for AI use by healthcare students, their attitudes towards such access to information, and their self-assessment of AI knowledge. The main conclusions are that AI is still not popular among students in the specialities "X-ray laboratory assistant" and "Midwife" at MU-Plovdiv. Students describe searching for information with AI as fast, convenient and easy. We can expect that AI will permanently enter as a way of learning and preparing extracurricular assignments. Students critically discuss the possibilities of large language models and point out advantages, but also find negatives. It requires student preparation as well as a framework and guidelines for using the technology. Our students will increasingly use the help of AI. This will happen with or without the approval of the teachers, so it is good to be prepared, to talk with them, to train them and together to set conditions and rules. The obtained results can provide guidelines for planning and conducting a wider study of the use of AI by students - attitudes, styles of use, need for training, etc. [ABSTRACT FROM AUTHOR]

Background: In addition to newborn screening, dried blood spots (DBSs) are used for a wide variety of analytes for clinical, epidemiological, and research purposes. Guidelines on DBS collection, storage, and transport are available, but it is suggested that each laboratory should establish its own acceptance criteria. Methods: An optical scanning device was developed to assess the quality of DBSs received in the newborn screening laboratory from 11 maternity wards between 2013 and 2018. The algorithm was adjusted to agree with the visual examination consensus of experienced laboratory personnel. Once validated, the algorithm was used to categorize DBS specimens as either proper or improper. Improper DBS specimens were further divided based on 4 types of specimen defects. Results: In total, 27 301 DBSs were analyzed. Compared with an annual DBS rejection rate of about 1%, automated scanning rejected 26.96% of the specimens as having at least one defect. The most common specimen defect was multi-spotting (ragged DBS, 19.13%). Among maternity wards, improper specimen rates varied greatly between 5.70% and 49.92%. Conclusions: Improper specimen rates, as well as the dominant type of defect(s), are mainly institution-dependent, with various maternity wards consistently showing specific patterns of both parameters over time. Although validated in agreement with experienced laboratory personnel consensus, automated analysis rejects significantly more specimens. While continuous staff training, specimen quality monitoring, and problem-reporting to maternities is recommended, a thorough quality assessment strategy should also be implemented by every newborn screening laboratory. An important role in this regard may be played by automation in the form of optical scanning devices. [ABSTRACT FROM AUTHOR]

Systems for disease vector control should be effective, efficient, and flexible to be able to tackle contemporary challenges and threats in the control and elimination of vector-borne diseases. As a priority activity towards the strengthening of vector control systems, it has been advocated that countries conduct a vector-control needs assessment. A review was carried out of the perceived needs for disease vector control programs among eleven countries and subnational states in South Asia and the Middle East. In each country or state, independent teams conducted vector control needs assessment with engagement of stakeholders. Important weaknesses were described for malaria, dengue and leishmaniases regarding vector surveillance, insecticide susceptibility testing, monitoring and evaluation of operations, entomological capacity and laboratory infrastructure. In addition, community mobilization and intersectoral collaboration showed important gaps. Countries and states expressed concern about insecticide resistance that could reduce the continued effectiveness of interventions, which demands improved monitoring. Moreover, attainment of disease elimination necessitates enhanced vector surveillance. Vector control needs assessment provided a useful planning tool for systematic strengthening of vector control systems. A limitation in conducting the vector control needs assessment was that it is time- and resource-intensive. To increase the feasibility and utility of national assessments, an abridged version of the guidance should focus on operationally relevant topics of the assessment. Similar reviews are needed in other regions with different contextual conditions. Author summary: Vector control can play a major role in the control and elimination of vector-borne diseases, such as malaria, dengue, leishmaniases and other vector-borne diseases. However, to reach its potential, national vector control systems should be adequately supported by vector surveillance, community participation and intersectoral collaboration. As a step towards strengthening vector control, it has been advocated that countries conduct a vector-control needs assessment. The authors reviewed the needs or gaps as perceived by stakeholders of disease vector control programs in eleven countries and subnational states in South Asia and the Middle East. Programs for control and elimination of malaria, dengue and leishmaniases had major shortcomings in vector surveillance and entomological capacity. This was a concern because vectors develop insecticide resistance which, if unchecked, could reduce the effectiveness of interventions. Also, attaining elimination of disease demands enhanced vector surveillance support. There were major gaps in community mobilization and intersectoral collaboration. The findings imply that vector control systems should adapt to the changing disease situation and adopt a cross-disease mandate. The authors propose improvements to the methods of needs assessment.

Open science practices have led to an increase in available speech datasets for researchers interested in acoustic analysis. Accurate evaluation of these databases frequently requires manual or semi-automated analysis. The time-intensive nature of these analyses makes them ideally suited for research assistants in laboratories focused on speech and voice production. However, the completion of high-quality, consistent, and reliable analyses requires clear rules and guidelines for all research assistants to follow. This tutorial will provide information on training and mentoring research assistants to complete these analyses, covering areas including RA training, ongoing data analysis monitoring, and documentation needed for reliable and re-creatable findings.

MALDI-ToF MS has become a cornerstone of the clinical microbiology laboratory. The reliability and ease-of-use of these instruments make them a popular choice of study to expand their applications and increase efficiency. The use of artificial intelligence has rapidly expanded in recent years and efforts are underway to integrate this technology into the clinical microbiology laboratory to expand the applications of MALDI-ToF MS and advance beyond current limitations in the identification of clinical isolates. At the same time as the rise of AI, clinical laboratories are facing pressure to increase efficiency due to the critical shortage of qualified laboratory personnel. Studies examining the performance of simplified testing workflows seek to help laboratorians do more with less. The improvement and creation of additional databases is also improving the rate of successful identifications. This review seeks to provide an update on recent developments around these topics.

Compelling evidence is presented that Glauber worked as a laborator (laboratory assistant) for Landgrave Georg of Hesse-Darmstadt from 1632/33 till he was appointed apothecary in Giessen in 1635. During this time, he was also used as laborator by the landgrave's personal physician, Helwig Dieterich. Glauber became a famous chemist, whose alchemical secrets were keenly solicited by King Frederik III of Denmark, Queen Christina of Sweden, and, according to the 1662 diary of Ole Borch, King Charles II of England. A 1689 letter to Queen Christina contains detailed descriptions of Glauber's alkahest, his decomposition and redintegration of saltpeter, and his 'most secret sal armoniacum', which is interpreted here for the first time.

* Context.--Two major categories of laboratories performing nonwaived testing under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) are the Certificate of Accreditation (CoA) and Certificate of Compliance (CoC) laboratories. Accreditation organizations collect more detailed laboratory personnel information than the Centers for Medicare & Medicaid Services (CMS) Quality Improvement and Evaluation System (QIES). Objective.--To estimate total numbers of testing personnel and testing volumes in CoA and CoC laboratories, by laboratory type and state. Design.--We developed a statistical inference method by using the respective correlations between testing personnel counts and test volume by laboratory type. Results.--QIES reported 33 033 active CoA and CoC laboratories in July 2021. We estimated testing personnel to be 328 000 (95% CI, 309 000-348 000), which is supported by the count of 318 780 reported by the US Bureau of Labor Statistics. There were twice as many testing personnel in hospital laboratories as in independent laboratories (158 778 versus 74 904, P < .001). Independent laboratories had the highest test volume per person, which was twice as high as physician office laboratories (62 228 versus 30 102, P < .001). Hospital and independent laboratories comprised 34% of all CoA and CoC laboratories but performed the largest portion of testing (81%). Physician office laboratories, accounting for 44% of all CoA and CoC laboratories, performed a comparatively low proportion of total tests (9%). Conclusions.--Numbers of testing personnel vary considerably by laboratory type and across states. These data can provide valuable insight when assessing laboratory workforce training needs and planning for public health emergencies. [ABSTRACT FROM AUTHOR]

Decalcification is crucial in histological processing, particularly for studying mineralized tissues like bone. The choice of decalcification method can significantly impact the quality of histological sections and the preservation of tissue morphology. This study aims to establish a standardized protocol for decalcifying rat calvarial bone using a formic acid-formalin-based decalcification solution. The protocol was systematically optimized and evaluated based on various parameters, including decalcification time, formic acid concentration, and tissue integrity preservation. The decalcification process was evaluated through comprehensive assessments, including gross physical examination, chemical analysis, and radiographic imaging techniques. Our result demonstrated that the 10% formic acid concentration proved most effective for decalcifying rat calvarial bone samples within eight days, excelling in mineral content removal while preserving specimen structural integrity. In contrast, the 5% concentration failed to complete decalcification within ten days, and the 15% compromised sample quality within eight days. Histological analyses confirmed the efficacy of the 10% formic acid concentration in maintaining tissue integrity and achieving optimal staining quality. The standardized protocol presented in this study provides an effective and reliable approach for achieving consistent and high-quality histological sections of rat calvarial bone. An ideal decalcification agent should effectively remove calcium salts, preserve structural integrity and molecular components, facilitate rapid yet minimally damaging decalcification, and ensure ease of handling for laboratory personnel. Further exploration of its applicability to different bone types or species is recommended to broaden its research utility. [ABSTRACT FROM AUTHOR]

Background: An essential factor in the validity of motor evoked potential (MEP)s recorded by transcranial magnetic stimulation (TMS) over multiple times is their test-retest reliability which to a large extent depends on the accuracy and competence of the assessor (intra-rater reliability). However, intra-rater reliability is infrequently reported in TMS studies suggesting that this is rarely done. Objectives: This study was conducted to determine the intra-rater within and between-session reliability of a newly trained TMS assessor prior to a main TMS study and report on the methodology used to encourage similar practice. Methods: Fourteen (10 males, 4 females; mean age: 32 ± 5.8 years) participants took part in the study. Motor evoked potentials were elicited from a relaxed, right first dorsal interosseous (FDI) muscle three times (T1, T2 and T3) across two testing sessions at least 48 hours apart. During the first session, MEPs were recorded twice (T1 and T2) within an interval of 20 minutes to determine the within (intra) session reliability of the assessor. During the second session, a single measurement was carried out (T3) which was compared to T1 to determine the inter-session reliability. Results: Repeated measure analysis of variance (ANOVA) did not reveal significant difference in the amplitude of the MEPs obtained across the three time periods (P = 0.196) demonstrating agreement in the MEPs and hence the reliability of the assessor. Additionally, the intraclass correlation coefficient (ICC) between T1 and T2; and T1 and T3 were 0.952 (P < 0.001) and 0.833 (P = 0.001) respectively further indicating the within and between sessions reliability of the assessor. Conclusions: The agreement between the three measured MEPs amplitude and the significant ICC demonstrates the reliability of the assessor in this study to use TMS for research. We suggest that the intra-rater reliability of new TMS operators should be established using the methodology in this report prior to main TMS studies. [ABSTRACT FROM AUTHOR]

This comprehensive review explores the critical importance of the preanalytical phase in hematology laboratory testing and its significant impact on the overall quality of results. The preanalytical phase encompasses all the processes from sample collection to sample preparation, and any errors during this stage can lead to inaccurate and unreliable hematological data. By systematically examining the various sources of preanalytical errors, including specimen collection, transportation, and handling, this review provides insights into the potential challenges faced in the hematology laboratory. Furthermore, the article discusses a range of effective prevention strategies to mitigate preanalytical phase errors and enhance the reliability of hematological test results. These strategies encompass improvements in staff training, standardization of collection procedures, implementation of quality control measures, and advancements in technology and automation. The review emphasizes the importance of fostering a culture of awareness and adherence to best practices in the laboratory setting. Preanalytical errors remain a major concern in every laboratory because the majority of the stages leading up to these errors are not within the direct control of the laboratory. Even though they cannot be eliminated, they can definitely be minimized. The preanalytical errors of a hematology laboratory can be reduced with the help of quality management systems, personnel training, regular audits, and automation in the preanalytical stage, thus increasing the accuracy of the results and providing better patient care.

Background: Urinary sediment is an important part of routine urine test, which plays an irreplaceable role in the diagnosis of diseases, monitoring of treatment effect, and prognosis judgment [1]. Methods: Through the results of urine dry chemistry and microscopic examination of urinary sediment, we interpreted and analyzed the clinical significance of urinary casts in urinary sediment. Results: In patients with new urinary system diseases abnormal urine results appear earlier than changes in serum renal function indicators, especially when the urine sediment shows typical casts, which can provide an important basis for clinical diagnosis. Conclusions: Clinical laboratory personnel should attach great importance to the morphological examination of urinary sediment and master the diagnostic significance of the formed components of urinary sediment for various diseases, so as to better assist clinical disease diagnosis.

Glanders is a highly infectious and notifiable disease of equines that occurs due to Burkholderia mallei. In India, glanders re-emerged in 2006 and thereafter regular outbreaks have been reported in various states (n = 14). Frequent and prolonged contact with equids with glanders may transmit B. mallei infection to humans. This study was designed to learn more about the Knowledge, Awareness and Perception (KAP) of veterinarians, para veterinarians, and physicians about equine glanders, which will help in enhancing the nation-wide glanders eradication programme. A total of 165 respondent's from 11 Indian states and one union territory were surveyed. Most of the respondents (n = 160) were from equine glanders affected or endemic states. Knowledge gap analysis revealed that 40.3 and 22% of the participants were not aware of government regulations and the transmission of glanders, respectively. These are major concerns given the wide spread occurrence of disease in the country. Awareness test on glanders revealed that 65(39.4%) participants would collect biological samples for laboratory confirmation, 67(40.6%) would inform the concerned authorities and 106 (64.2%) replied that they would eliminate the glanders infected equines. Analysis of perception towards equine glanders showed that majority of the participants (n = 113, 68.4%) observed that equine keepers were reluctant to disclose the clinical symptoms of B. mallei infection. Furthermore, non-cooperation and unwillingness by superiors (33.9%), financial (31%), administrative (28.4%), and technical limitations (27.8%) were major constraints under the perception analysis. This study reveals that veterinarians need to be educated on governmental policies and guidelines on equine glanders with regular training and awareness programs. Intersectoral co-ordination to investigate human glanders is also needed. [ABSTRACT FROM AUTHOR]
