Developing a competency assessment framework for medical laboratory technologists in primary healthcare settings in India.

Medical Laboratory Technologists play a significant role in delivering quality laboratory Services. The competency assessment of MLTs is a critical driver for enhancing primary healthcare performance. While several countries have developed competency frameworks for MLTs in primary care, such frameworks are lacking in the Indian context. This study aimed to create a competency assessment framework to assess the competencies of MLTs (Medical Laboratory Technologists) working in Indian public primary healthcare facilities. The research followed a five-step process, starting with a review of existing literature on MLTs' competencies in primary healthcare. Expert consultations were then conducted to establish a consensus on these competencies. Following this, assessment tools were developed based on the literature review and expert input. Another round of expert consultations was held to ensure agreement on the assessment tools. Finally, the developed tools were tested in a public primary healthcare facility. The literature review identified 86 competencies across 11 domains: safe work practices, data/ sample collection, specimen preparation equipment instruments and regiments, assessment and analysis, recording and reporting, infection control, quality management, critical thinking, communication and interaction, and professional practice. Expert consultations resulted in the consensus on ninety-five competencies in ten domains of MLTs in primary healthcare settings. Competencies for each domain were discussed and agreed upon. A competency assessment tool was finalized after unanimous agreement among experts. The competency assessment tool was later finalized after pre-testing on MLTs in a clinical laboratory part of a public primary health care facility. This study successfully developed a competency assessment framework for in-service MLTs in Indian public primary healthcare settings. The framework encompasses ninety-five competencies covering ten domains of MLT responsibilities. It provides a comprehensive tool for assessing MLT's competencies and identifying competency gaps. The framework can be used to capacitate MLTs, improve their performance in primary healthcare settings, and enhance the delivery of healthcare services in India. It bridges a critical gap in the existing literature and can aid as a valuable resource for policymakers, educators, and healthcare professionals involved in practicing medical laboratory Services in primary healthcare settings.

Transient Abnormal Myelopoiesis: An Abnormal Course and the Efficacy of Delayed Treatment.

Transient abnormal myelopoiesis (TAM) is observed in a few neonates with Down syndrome. While a large proportion undergo complete remission without any treatment, some of them can develop myeloid leukemia of Down syndrome (ML-DS) in the future. Without proper treatment, mortality can be high. Here we have described an interesting and difficult-to-treat case of a neonatal with Down syndrome who presented with anemia, thrombocytopenia, and 75% blasts. We came across multiple challenges in treatment due to severe pneumonia.

A Cross-Sectional Survey on the Use of Tobacco, Attempts on Cessation, and Locus of Control Among College Students.

Background Socio-cultural considerations (such as drug availability) and psychological traits play a significant role in predicting whether a person will use drugs in the future and dependency on the drugs. Second-, third-, and fourth-hand smoking and E-cigarettes are influencing factors for the use of tobacco in college students. This study conducted research to ascertain whether there is a potential relationship between tobacco consumption and various factors, including internal and external control sites and demographics. Materials and methods Participants in the study were found by walk-up distribution at multiple campus-wide smoking places, department announcements, and on-campus advertisements. Social media and participant references were also used in this study as recruitment tools. In addition, the locus of control questionnaire also identifies if the participating individual had extrinsic or intrinsic reinforcing routines. The classification of the participating individuals into respective internal and external locus of control was in accordance with their response survey after which a statistical analysis was done. Results This study found an association between smoking on campus and reported attempts to quit. Additionally, there is a strong association (r(85) = 0.31, p < 0.01) between reported tobacco use status and cigarette use on campus. Participants' gender and smoking status also had r(85) = 0.39, p-value < 0.01 correlation. The bulk of respondents indicated that they were seniors and off-campus living concluding for 36% (n = 34) and 60% (n = 51) of the total. Twenty-seven percent (n = 24) of the respondents were first-year college students and the rest 33% (n = 29) said their parents had no college education at all or incomplete college education. Conclusion Whenever there is a strong perception of organizational support for anti-tobacco policies, and improving compliance, there is a drastic increase in cigarette cessation and a drop in tobacco usage among those who still smoke. Perceived organizational support is strongly and positively connected with cessation among the organization's members.

A comparative evaluation of the quality of cryoprecipitate prepared from 350 ml versus 450 ml of whole blood and different methods of thawing of plasma: A prospective observational study.

INTRODUCTION: Cryoprecipitate is used in conditions like hypofibrinogenemia, massive transfusion with bleeding, and factor XIII deficiency. The current guidelines support the preparation of cryoprecipitate from 450 ml whole blood. But 350 ml of whole blood collection is expected from low body weight (<55 kg) donors. However, no standardized criteria exist for preparing cryoprecipitate from 350 ml of whole blood. AIM OF THE STUDY: This study compared the fibrinogen and factor VIII levels in cryoprecipitate units prepared from 350 ml versus 450 ml whole blood collection. The study also compared the fibrinogen and factor VIII levels prepared by circulating water bath versus blood bank refrigerator (BBR) thawing method. METHODOLOGY: A total of 128 blood bags were equally divided into groups A and B for 450 and 350 ml whole blood collection further subdivided into subgroups based on thawing methods. The fibrinogen and factor VIII yield were analyzed in the cryoprecipitates prepared from both groups. RESULTS: The factor VIII levels were significantly higher in cryoprecipitate made from 450 ml whole blood collection (P = 0.02). The BBR method of plasma thawing resulted in better fibrinogen recovery than the cryo bath method. Whereas vice versa in the case of factor VIII recovery. A weak but significant positive correlation was noted in factor VIII levels with the plasma volume. CONCLUSION: Over 75% of the cryoprecipitates prepared from 350 ml whole blood passed the fibrinogen and factor VIII quality control criteria. So, 350 ml whole blood collection from low body weight (<55 kg) donors could be utilized to prepare cryoprcipitates. However, future clinical studies should focus on the cryoprecipitate's clinical efficacy prepared from 350 ml of whole blood.

Gingival hyperplasia: An initial oral manifestation of acute myeloid leukemia.

Various systemic diseases can manifest oral signs and symptoms early, which may be crucial for diagnosis and outlining the treatment plan. This case report highlights the presentation of acute leukemia (a malignancy of white blood cells) in a young female. An 11-year-old girl presented with gingival overgrowth and bleeding from the gingiva, weakness, and recent history of weight loss. A detailed workup consisting of complete blood count, bone marrow examination, flow cytometric immunophenotyping, cytogenetics, and molecular studies were carried out. The investigations confirmed the infiltration of blast cells of myelomonocytic origin, and a confirmatory diagnosis of acute myeloid leukemia (French-American-British classification M5) was made. The patient was put on induction chemotherapy and responded well. She developed febrile neutropenia following chemotherapy, which was managed conservatively. Gingival overgrowth subsided after the chemotherapy, and at the time of discharge, she was asymptomatic and hemodynamically stable. The oral health-care professionals must recognize that gingival overgrowth/enlargement may represent an initial manifestation of an underlying systematic disease.

Comparison of flowcytometry-based scoring system for the diagnosis of early T precursor-acute lymphoblastic leukemia.

BACKGROUND: Early T cell precursor-acute lymphoblastic leukemia (ETP-ALL) is a hematolymphoid malignancy where the blasts demonstrate T cell differentiation markers along with stem cell and myeloid antigen expression. The differential diagnosis of ETP-ALL from non-ETP ALL and mixed phenotype acute leukemia is often challenging due to its overlapping immunophenotypic picture with co-expression of myeloid antigens. In this study, we endeavored to describe the immune-phenotype profile of ETP-ALL in our patients and compared the utility of four different scoring systems for better discrimination of these entities. METHODS: This retrospective analysis included 31 ETP-ALL out of 860 acute leukemia cases consecutively diagnosed at the two tertiary care centers. Flowcytometry-based immunophenotype was reviewed for all the cases, and the utility of four flow-based objective scorings was assessed for the diagnosis of ETP-ALL. Receiver operating curves were drawn to compare the different flow-based scoring systems. RESULTS: The prevalence of ETP-ALL was 40% (n = 31/77 T-ALL) in our study group, comprised mainly of adults with a median age of 20 years. The five-marker scoring system had the maximum area under the curve, followed by the seven-marker scoring system. A cut-off of ≥2.5 was more specific (sensitivity: 91%; specificity: 100%), while a score of ≥1.5 was more sensitive but slightly less specific (sensitivity: 94%, specificity: 96%). CONCLUSION: The WHO criteria for the diagnosis of ETP-ALL should be followed across all laboratories to avoid confusion and for better treatment stratification. Flow-based scoring systems can be objectively employed for better detection of cases.

Restoration of Altered Oncogenic and Tumor Suppressor microRNA Expression in Breast Cancer and Colorectal Cancer Cell using Epicatechin.

BACKGROUND: MicroRNAs (miRNA) are small non-coding RNAs that regulate the function of mRNA post-transcriptionally in a tissue-specific manner. miRNA expressions are heavily dysregulated in human cancer cells through various mechanisms, including epigenetic changes, karyotype abnormalities, and miRNA biogenesis defects. miRNAs may act as either oncogenes or tumor suppressors under different conditions. Epicatechin is a natural compound found in green tea which possesses antioxidant and antitumor properties. OBJECTIVE: The objective of this study is to investigate the effect of epicatechin treatment on the expression level of several oncogenic and tumor suppressor miRNAs in breast and colorectal cancer cell lines (MCF7 and HT-29) and identify its mechanism of action. METHODS: The MCF-7 and HT29 cells were treated with epicatechin for 24 hours and untreated cells were considered control cultures. miRNA was isolated and qRT-PCR was used to measure the expression profile changes of different oncogenic and tumor suppressor miRNAs. Furthermore, the mRNA expression profile was also screened at different concentrations of epicatechin. RESULTS: Our results showed several-fold changes in miRNAs expression level, which is cell line specific. Also, epicatechin at different concentrations induces biphasic changes in mRNA expression levels in both cell lines. CONCLUSION: Our findings first time demonstrated that epicatechin can reverse the expression of these miRNAs and may trigger the cytostatic effect at a lower concentration.

The Effectiveness of Herbal Versus Non-Herbal Mouthwash for Periodontal Health: A Literature Review.

Dental plaque is a biofilm of microorganisms that present naturally on the exposed tooth surface; it is the main etiological factor for many periodontal conditions and other oral health issues and its regular removal from the oral cavity can prevent many periodontal problems. Despite several experiments using herbal oral care products to reduce dental plaque or gingivitis, the findings remain inconclusive. We performed a systematic literature search on PubMed and Cochrane Library for randomized controlled trials (RCTs) dating from 2001 up to and including the year 2021. The keywords and Medical Subject Headings (MeSH) terms comprised combinations of the following: herbal, clove oil, peppermint oil, ginger, basil, ajwain, betel leaf extract, neem, lavender, non-herbal, chlorhexidine, fluorides, hydrogen fluoride, hydrogen fluoride, stannous fluoride, and mouthwashes. Each of the titles that the search elicited was screened and duplicates were removed from the gathered results. The full-text versions of the remaining articles were downloaded and examined by title and abstract. Handsearching was not carried out. We initially identified 21 studies; 14 studies, which did not fulfill the selection criteria, were excluded. All the included studies reported a reduction in plaque index (PI) and gingival index (GI) scores in both herbal and non-herbal groups. Two studies reported the superiority of the non-herbal mouthwash over the herbal one while five of the studies showed no significant difference in PI and GI scores between herbal and non-herbal mouthwash, implying equal efficacy of both, i.e., Triphala, aloe vera, tea tree, and polyherbal groups like Zingiber officinale, Rosmarinus officinalis, and Calendula officinalis, and chlorhexidine. Current research suggests that herbal mouthwashes are as effective as non-herbal mouthwashes for reducing dental plaque in the short term; however, the evidence is based on low-quality trials.

Usefulness of Leucocyte Cell Population Data by Sysmex XN1000 Hematology Analyzer in Rapid Identification of Acute Leukemia.

Leukocyte cell population data (CPD) generated by hematology auto analyzers are reported to be useful in screening of sepsis patients. However, there is a paucity of literature highlighting the utility of CPD in screening of acute leukemias (AL). Leucocyte CPD obtained by Sysmex XN1000 hematology analyzer from 210 cases of ALs [22 acute promyelocytic leukemia (APL), 79 non-APL acute myeloid leukemia (non-APL-AML) and 109 acute lymphoblastic leukemia (ALL)] were compared with 100 healthy and 52 reactive controls. Receiver operator curves were drawn to determine the cut-off values of individual parameters. The regression equations combining the best parameters were then formulated to calculate a cut-off value for discrimination among AL subgroups and controls. Acute leukemias showed significant differences (p < 0.05) in various CPD parameters compared to control subjects. A combination of best CPD parameters discriminated ALs from healthy controls (cut off; 0.443, sensitivity of 94% and specificity of 91%), ALs from reactive controls (cut off; 0.576, sensitivity; 97%, specificity; 92%), APL from non-APL-AML (cut off; 0.174, sensitivity of 91% and specificity of 67%), and AML from ALL (cut off; 1.338, sensitivity; 86.1%, specificity; 75%). The CPD from Sysmex XN 1000 analyzer could be a useful tool in screening and lineage characterization of acute leukemias; particularly at centers where high-end technical expertise is still not available.

Rapid screening of dengue fever using research parameters from new generation hematological analyzers.

INTRODUCTION: The early diagnosis of dengue fever and its differentiation from other causes of acute febrile illness is essential for a better outcome. The new generation automated hematology analyzers provide parameters like high fluorescence lymphocyte count (HFLC) and leukocyte cell population data (CPD) representing various leukocytes. We tried to analyze the utility of these parameters in the rapid screening of dengue fever. METHODS: The HFLC and the leukocytic CPD from the Sysmex XN1000 analyzer were obtained for 299 cases presenting with acute febrile illness, which included 97 dengue-positive and 202 cases dengue-negative controls. Additionally, 100 healthy controls were also included. The Receiver operative curves (ROC) were drawn to obtain a cut-off value for these parameters for discriminating among the dengue-positive and dengue-negative subgroups and healthy controls. RESULTS: The dengue-positive cases showed a significantly increased HFLC among the different groups of controls. The median (range) HFLC% was 1.9(0.30-6.55), 0.20(0.10-0.70), and 0.10(0.0-0.30) in the cases that were positive for dengue, negative for dengue, and healthy controls, respectively. The ROC analysis revealed HFLC% at a cut-off value of 1.75 which can discriminate between dengue-positive and dengue-negative patients, with 52% sensitivity, 90% specificity, 72% positive predictive value (PPV), and 80% negative predictive value (NPV). The regression analysis revealed LY-X, LY-Z, Ly-WX, LY-WZ, and MO-X as independent predictors for dengue fever. CONCLUSION: The HFLC and CPD obtained from Sysmex XN1000 hematology analyzer are valuable tools in rapidly screening dengue infection from other febrile illnesses in routine practice.

Peripheral blood T lymphocytosis in thymoma: an insight into immunobiology.

PURPOSE: Peripheral blood T lymphocytosis (PBTL) is a rare, yet poorly understood manifestations of thymoma, which is postulated to be linked with autoimmune/paraneoplastic manifestations such as myasthenia gravis (MG), pure red cell aplasia (PRCA), etc.; more commonly encountered in this neoplasm. METHOD: We aim to describe the flowcytometric immunophenotypic data of PBTL in a 43-year-old male; 6 months after successful completion of chemoradiotherapy (CT/RT) for a large, invasive, and metastatic type B1 thymoma; and present a comprehensive review of all such cases reported over last 42 years (N = 21) (1977-2019). RESULT: A larger size of the tumors (≥ 10 cm), presence of local invasion and/or distant metastasis, and type B (cortical or lymphocyte rich) histology were more likely to be associated with PBTL. Tumors associated with MG/PRCA (N = 9/21) tend to have lower PBTL compared to those without such manifestations; and PBTL subsided following thymectomy with or without CT/RT. Immunophenotypic analysis of PB revealed a CD8 + > CD4 + mature (naïve) polyclonal T cells resembling late cortical thymocytes. CONCLUSION: Thymic intratumoral microenvironment might influence occurrence PBTL that may have a pathophysiologic link to development of autoimmune manifestations. Immunophenotypic characteristics of peripheral blood lymphoid cells should be the clue for accurate characterization and to avoid a misdiagnosis of a lymphoproliferative neoplasm.

Pediatric neuroblastic tumors: A critical evaluation of cytomorphological features for risk stratification on aspiration cytology.

BACKGROUND: Neuroblastic tumor (NT) is the most common extracranial solid tumor of childhood with variable outcome which again depends on risk stratification related to distinct biology of the tumor. The use of fine-needle aspiration (FNA) material for evaluation of cytomorphological parameters and risk stratification in NTs using cytology prognostic score (PS) is limited in routine practice. METHODS: We reviewed 38 FNA cytology cases diagnosed as pediatric small round cell tumor between time period June 2017 to December 2019 for clinical, cytomorphological and immunohistochemical features. RESULTS: Ten out of 38 small round cell tumors were NTs. All 10 cases were further subclassified according to International Neuroblastoma Pathology Classification into undifferentiated neuroblastoma (n = 1), poorly differentiated neuroblastoma (n = 5), differentiating neuroblastoma (n = 2), and ganglioneuroblastoma (n = 2). Cytologic PS was done using the morphological criteria as described previously in literature. The patients were divided into favorable and unfavorable cytomorphological prognostic categories with a cut off scoring of 12. A score of more than 12 is associated with high risk morphology and advanced stage. All cases with PS > 12 (n-4) (unfavorable cytomorphology) had a poor outcome compared to six patients with PS < 12 (n-6) (favorable cytomorphology). CONCLUSION: Aspiration cytology can be used as a first line investigation to evaluate the cytomorphological features for risk stratification and diagnosis in patients with NTs using cytological prognostic scoring system. A larger multi-centric validation study necessitates for cytological risk stratification.

Exflagellation of Plasmodium vivax in peripheral blood: An uncommon finding and its significance.

Malaria continues to be a major public health problem. The life cycle of malaria is completed in two hosts Anopheles mosquito - definitive host and humans - the intermediate host. Exflagellation of microgametocyes in the life cycle of Plasmodium vivax occurs in mosquitoes and is rarely seen in human peripheral blood. Less than 15 occurrences of exflagellated microgametocyte of Plasmodium species have been reported to date. The appearance of exflagellated microgametes in human blood may pose a diagnostic dilemma due to its resemblance with other hemoparasites such as Borrelia and Trypanosoma.

End-of-life care attitudes, values, and practices among health care workers.

INTRODUCTION: This study aims to ascertain attitudes of health care workers on end-of-life care (EOLC) issues and to highlight the disparity that exists in countries with different backgrounds. METHODS: It is a cross-sectional questionnaire survey across heterogeneous health care providers in India, Chile, the United Kingdom, and the Netherlands using an indigenously prepared questionnaire considering regional variations, covering different areas of EOLC. RESULTS: Of the 109 participants, 68 (62.4%) felt that cardiopulmonary resuscitation should be done selectively, 25 (22.9%) had come in contact with at least 1 patient who had asked them to hasten death, and 36 (33%) felt that training was insufficient to prepare them for skills in issues of EOLC. CONCLUSION: To avoid cumbersome through well-meant interventions, it is important that the caregiving team is aware of the patient's own wishes with respect to EOLC issues.

Coagulopathy as prognostic marker in acute traumatic brain injury.

CONTEXT: Coagulopathy frequently occurs following traumatic brain injury (TBI) and usually occurs 6-72 hour post-trauma. The incidence and the probable risk factors for development of coagulopathy and poor outcome following TBI are largely unknown and vary considerably. AIMS: To assess the incidence and probable risk factors for development of coagulopathy and to identify the risk factors for poor outcome in terms of median survival time following TBI. MATERIALS AND METHODS: In this prospective study over two years, patients of isolated moderate and severe traumatic brain injury (GCS≤12) admitted to trauma center had coagulation profile (PT, APTT, thrombin time, fibrinogen and D-dimer), arterial lactate and ABG analysis done on day of admission and on day three. Coagulopathy was defined as prothrombin time (PT) or/and activated partial thromboplastin time (APTT) more than 1.5 times the normal control. Incidence of in-hospital mortality was assessed in all cases. STATISTICAL ANALYSIS: A stepwise logistic regression analysis was performed to identify risk factors for coagulopathy and mortality in these patients. RESULTS: A total of 208 patients were enrolled in the study. The mean age was 32 ± 12 years and mean GCS was 7.1 ± 2.8. Coagulopathy was present in 46% (n = 96) of patients. Risk factors for development of coagulopathy were found out to be severity of head injury (OR: 2.81), elevated D-dimer (OR: 3.43), low hemoglobin (OR: 3.13), and effaced cisterns in the CT scan (OR: 2.72). Presence of coagulopathy (OR: 2.97) and severity of head injury (OR: 5.70) strongly predicted poor outcome, and were associated with a decreased median survival time. CONCLUSIONS: There is a high incidence of coagulopathy following TBI. The presence of coagulopathy as well as of severity of TBI are strong predictors of in-hospital mortality in these patients.

Hypofibrinogenemia in isolated traumatic brain injury in Indian patients.

Coagulation abnormalities are common in patients with head injuries. However, the effect of brain injury on fibrinogen levels has not been well studied prospectively to assess coagulation abnormalities in patients with moderate and severe head injuries and correlate these abnormalities with the neurologic outcome. Consecutive patients with moderate (Glasgow Comma Scale (GCS),9-12) and severe (GCS≤8) head injuries were the subjects of this pilot study, All patients had coagulation parameters, including plasma fibrinogen levels measured. Clinical and computed tomography (CT) scan findings and immediate clinical outcome were analyzed. Of the 100 patients enrolled, only seven (7%) patients had hypofibrinogenemia (fibrinogen ≤200 mg/dL). The head injury was moderate in two patients and severe in five patients. Fibrinogen levels showed a progressively increasing trend in four patients (three with severe head injuries and one with moderate head injury). CT scan revealed subdural hematoma in five patients; extradural hematoma in one; and subarachnoid hemorrhage in another patient. Of the seven patients, two patients died during hospital. Large-scale prospective studies are needed to assess the fibrinogen level in patients with head injury and its impact on outcome.
