VARK preference and perception of online versus offline professional development training of medical laboratory technologists.

OBJECTIVE: This study aims to understand the learning preferences and perception of medical laboratory technologists on sudden shift from offline to online training sessions during COVID-19 pandemic. METHODS: Microsoft form containing twenty-four questions was circulated to the twenty-five laboratory technologists after 1 year of online continuous professional development training. VARK questionnaire was circulated to understand the learning style. RESULTS: Provision of recording lectures, significant reduction of performance anxiety, anxiety associated with criticism, and QA sessions emerged as the major positive aspects of a virtual training platform. Analysis of learning preferences revealed that most technologists had a unimodal aural (45%) or kinesthetics (33%) than visual (11%) and reading (11%) learning preference. In bimodal learning preference, AK (44.44%) emerged as the predominant form. Forty percent of the technologists showed trimodal learning pattern with 50% among them showing an ARK pattern while 25% each showing VAK and VRK patterns of learning preferences. CONCLUSION: Medical laboratory technologists adapted well to the sudden shift from offline to online continuous development programs. However, efficient managerial mechanisms to address the major perceived hurdles and designing a multimodal training module to accommodate the learning preferences of our technologists can ensure enthusiastic participation and effective learning among medical laboratory technologists.

Incorporation of plasma Vitamin C levels to modified nutritional risk in critically ill score as the novel Vitamin C nutritional risk in critically ill score in sepsis subjects as an early predictor of multidrug-resistant bacteria: A prospective observational study.

Background: On intensive care unit (ICU) admission, it is difficult to predict which patient may harbor multidrug-resistant (MDR) bacteria. MDR is the nonsusceptibility of bacteria to at least one antibiotic in three or more antimicrobial categories. Vitamin C inhibits bacterial biofilms, and its incorporation into the modified nutritional risk in critically ill (mNUTRIC) scores may help predict MDR bacterial sepsis early. Methods: A prospective observational study was conducted on adult subjects with sepsis. Plasma Vitamin C level was estimated within 24 h of ICU admission, and it was incorporated into the mNUTRIC score (designated as Vitamin C nutritional risk in critically ill [vNUTRIC]). Multivariable logistic regression was performed to determine if vNUTRIC was an independent predictor of MDR bacterial culture in sepsis subjects. The receiver operating characteristic curve was plotted to determine the vNUTRIC cutoff score for predicting MDR bacterial culture. Results: A total of 103 patients were recruited. The bacterial culture-positive sepsis subjects were 58/103, with 49/58 culture-positive subjects having MDR. The vNUTRIC score on ICU admission in the MDR bacteria group was 6.71 ± 1.92 versus 5.42 ± 2.2 in the non-MDR bacteria group (P = 0.003, Independent Student's t-test). High vNUTRIC score ≥6 on admission is associated with MDR bacteria (P = 0.042 Chi-Square test), and is a predictor of MDR bacteria (P = 0.003, AUC 0.671, 95% confidence interval [0.568-0.775], sensitivity 71%, specificity 48%). Logistic regression showed that the vNUTRIC score is an independent predictor of MDR bacteria. CONCLUSION: High vNUTRIC score (≥6) on ICU admission in sepsis subjects is associated with MDR bacteria.

Dyslipidaemia and inflammatory markers as the risk predictors for cardiovascular disease in newly diagnosed premenopausal hypothyroid women.

Background: Hypothyroidism can predispose systolic and diastolic cardiac dysfunction, increased peripheral vascular resistance, endothelial dysfunction, altered coagulopathy, and dyslipidemia resulting in atherosclerosis. Thyroid hormones can influence homocysteine metabolism by regulating the methylenetetrahydrofolate reductase (M THR). So, this study aimed to compare the markers homocysteine, high sensitive C-reactive protein (hs-CRP), and Atherogenic Indices (AI) between newly diagnosed hypothyroid and euthyroid premenopausal women. Methods: 80 Female patients between 20 and 45 years were enrolled in this study and were equally divided into cases and controls group. Laboratory tests included: i) Serum T3, T4, TSH was measured using electrochemiluminescence, ii) lipid profile, homocysteine, and hs-CRP were measured for all the participants. Atherogenic indices: Castelli risk indices I&II, Atherogenic coefficient (AEC), and Atherogenic Index of Plasma (AIP) were calculated using formulas. A comparison between the study groups was made by using the Independent t-test and Mann-Whitney U test. p-value < 0.05 was considered significant. Results: The hypothyroid group had significantly higher levels of homocysteine (p= 0.014), and hs-CRP (hs-CRP> 3.0 mg/L, 70% of participants have intermediate to high risk for a cardiovascular event) and elevated BMI compared to participants in the euthyroid group. Atherogenic indices (p< 0.001) was significantly increased in the hypothyroid participants' group. TC, TG , and LDL were significantly elevated in the hypothyroid group but did not show any association with systolic and diastolic blood pressure. Conclusions: Premenopausal women with hypothyroidism have a greater predisposition for cardiovascular disease compared to euthyroid.

Impact of anemia on sputum smear conversion and treatment outcomes among newly diagnosed tuberculosis patients in Southern India.

Background: Tuberculosis (TB) is a leading cause of mortality worldwide. The higher prevalence of anemia among TB patients is concerning due to its association with delayed sputum conversion and poor treatment outcomes. The present study aimed to evaluate the association of anemia with sputum smear conversion and treatment outcomes among TB patients. Methods: In a prospective community-based cohort study, TB patients were recruited from 63 primary health centers in the district. Blood samples were collected at baseline, at 2 months, and at the end of 6 months. Data were analyzed using SPSS software version 15. Results: Out of 661 patients recruited, anemia was observed among 503 (76.1%) participants. Prevalence of anemia was more among males 387 (76.9%) than 116 (23.1%) females. Out of 503 anemic patients, 334 (66.4%) had mild, 166 (33.0%) had moderate, and 3 (0.6%) had severe anemia at baseline. At 6-month treatment completion, 16 (6.3%) were still anemic. Among 503 anemic patients, 445 (88.4%) were given iron supplements and remaining 58 (11.6%) were managed with diet modifications. After completion of TB treatment, 495 (98.4%) patients had favorable treatment outcomes, whereas 8 (1.6%) patients had died. Severe anemia was not associated with poor outcomes. Conclusions: The presence of anemia among newly diagnosed TB patients, especially pulmonary TB was high. Increased risk of anemia was noted among males who were alcohol and tobacco consumers. There was no significant association between the presence of anemia and sputum conversion from baseline to 6 months of treatment completion.

Importance of Microminerals for Maintaining Antioxidant Function After COVID-19-induced Oxidative Stress.

Background: COVID-19 is caused by the Severe Acute Respiratory Distress Syndrome Coronavirus 2. Since the antioxidant mechanisms such as glutathione peroxidase or superoxide dismutase are downregulated during infection by the virus, there is an imbalance in the oxidant-antioxidant system. In this study we aimed to identify the effect of COVID-19 on the antioxidant defense mechanism by comparing the concentrations of antioxidants and microminerals in COVID-19 patients and healthy controls. Methods: This cross-sectional analytical study involved 200 patients at Kasturba Hospital, Manipal University. The serum concentrations of antioxidants and minerals were determined to establish the impact of COVID-19 on antioxidants mechanism and nutrient status in COVID-19 patients. Results: The serum concentrations of GPX (10.36 ± 2.70 ≥ 5.82 ± 1.64 mKAT/L, p < 0.0001) and copper (2192.5 ± 449.8 ≥ 782.15 ± 106.5 µg/dL, p < 0.0001) were significantly greater, and zinc (34.78 ± 4.5 ≤ 81.07 ± 10.13 µg/dL, p < 0.0001) was significantly less, in the study group than in controls. The Pearson correlation between serum SOD and zinc was significant (r = 0.491, p < 0.0001) indicating the importance of zinc in maintaining and improving SOD activity. No significant correlations were observed between copper and SOD (r = -0.089) or iron and CAT (r = -0.027). Conclusion: Our study demonstrated the expected increase in oxidant-radical production during COVID-19 by estimating the altered concentrations of antioxidants and the minerals required to neutralize the elevated ROS. This finding is not novel but adds to the existing literature, which recommends nutritional supplementation of microminerals and antioxidants.

Variability in Platelet-Rich Plasma Preparations Used in Regenerative Medicine: A Comparative Analysis.

Background: Platelet-rich plasma (PRP) and its derivatives are used in several aesthetic, dental, and musculoskeletal procedures. Their efficacy is primarily due to the release of various growth factors (GF), interleukins, cytokines, and white blood cells. However, the PRP preparation methods are highly variable, and studies lack consistency in reporting complete procedures to prepare PRP and characterize PRP and its derivatives. Also, all the tissue-specific (in vivo and in vitro) interactions and functional properties of the various derivatives/factors of the PRP have not been taken into consideration by any study so far. This creates a potential space for further standardization of the PRP preparation methods and customization of PRP/PRP derivatives targeted at tissue-specific/pathology specific requirements that would enable efficacious and widely acceptable usage of PRP as main therapy, rather than being used as adjuvant therapy. The main objective of our study was to investigate the variability in PRP preparation methods and to analyze their efficacy and reliability. Method: This study considered articles published in the last 5 years, highlighting the variability in their PRP preparation methods and characterization of PRP. Following the PRISMA protocol, we selected 13 articles for the study. The selected articles were assessed using NHLBI quality assessment tool. Results: We noted differences in (1) approaches to producing PRP, (2) extent of characterization of PRP, (3) small scale and large-scale preparation methods, (4) in vitro and in vivo studies. Conclusion: We identified two studies describing the procedures which are simple, reproducible, economical, provide a good yield of platelets, and therefore can be considered methods for further tissue-specific and pathology-specific standardizations of PRP and its derivatives. We recommend further randomized studies to understand the full therapeutic potential of the constituents of PRP and its derivatives.

Bisalbuminemia in a Hypothyroid Patient with Diabetes: A Case Report.

Bisalbuminemia is a rarely encountered anomaly characterized by presence of bifid albumin bands or a single widened albumin band in electrophoretogram. Inherited bisalbuminemia is quite rare and inherited as an autosomal dominant form. The acquired form of bisalbuminemia is usually transient and may be observed during long term beta lactam antibiotic therapy, acute pancreatitis, myeloma and nephrotic syndrome. This is a case of bisalbuminemia in 61-year-old diabetic female with hypothyroidism came with acute exacerbation of bronchial asthma.
