Utilization of Smartphones and Attitude Regarding Their Use at the Workplace by Nurses: A Cross-Sectional Study.

INTRODUCTION: The use of personal smartphones in healthcare settings is widespread, with nurses often integrating these devices into their profession's practices. This study addresses the utilization of and attitudes toward smartphone use among nurses in the workplace. METHODS: This study uses a descriptive cross-sectional design and includes 258 nurses from various departments in a tertiary care teaching and research hospital in India. Data was collected using Google Forms (Google LLC, Mountain View, California, United States) through a socio-demographic questionnaire and two scales: "Utilization of Smartphones at Workplace" and "Attitude Regarding Smartphone Use at Workplace." RESULTS:  The findings indicate that a significant proportion (64.3%) of participants use their smartphones for less than an hour at the workplace. Notably, a substantial majority (78.7%) agree that employers should implement a policy regarding smartphone use. Additionally, 34.1% use their smartphones for personal reasons for less than an hour, with 24.4% specifically engaging in social media use with a statistically significant difference (p <0.05). CONCLUSION: The study finds an enormous gap in nurses' smartphone use, with a greater emphasis on personal and social media activities than professional responsibilities. Establishing a collaborative regulatory framework is essential for aligning smartphone use with patient care obligations and ensuring a balance between possible benefits and risks.

Tobacco use in currently married pregnant & lactating women in India; key findings from the National Family Health Survey-5.

Background: Tobacco use among pregnant and lactating women carries dangerous repercussions for women and their children. Limited information is available at the national level on the prevalence and determinants of tobacco use in this vulnerable sub-population of women. This study aims to estimate the prevalence of tobacco use among currently married pregnant and lactating women and its association with demographic, behavioural and regional determinants in India. Methods: A cross-sectional study was conducted during which secondary data from the fifth National Family Health Survey, 2019-2020, was analysed. The prevalence and associated 95% confidence intervals (CI) for different forms of tobacco use were documented among currently married pregnant and lactating women. Adjusted Odds Ratio and 95% CI were calculated using multivariate logistic regression to identify the independent factors associated with different forms of tobacco use among respondents after applying sampling weights. Findings: In India, the prevalence of tobacco use among currently married pregnant and lactating women was 2.5% and 3.2%, respectively, with over 85% of tobacco-using currently married pregnant (85.6%) and lactating (85.6%) women using smokeless tobacco (SLT) only. Age group 30-34 years, working women and the richest wealth quintile were found to be independent predictors of smoked tobacco use among currently married pregnant women. In contrast, among the currently married lactating women, the middle wealth quintile and South Indian region were found to be independent predictors of smoked tobacco use. Interpretation: Smokeless tobacco was found to be the most prevalent type of tobacco consumed by pregnant and lactating women in India. There is an urgent need to curb tobacco use in this vulnerable sub-population of women in the country by sensitising them to the harmful consequences of tobacco use by integrating tobacco awareness and cessation services during routine ante-natal examinations. Funding: No funding was received for this study.

Predictors of anxiety and depression in operating room nurses during the COVID-19 pandemic: A multi-center cross-sectional study.

BACKGROUND: Operating room nurses (ORNs) who directly deal with the treatment and care of COVID-19 patients during the pandemic are at risk in terms of psychological stress and other mental health problems. OBJECTIVE: The aim of the study was to compare the anxiety and depression levels of ORNs working in different countries in the COVID-19 outbreak, and to determine the predictors and the difference between countries. METHODS: This was a descriptive and cross-sectional study. Data were collected online using a google form between February 2021-February 2022. The universe of the research is nurses who are members of national Perioperative Nurses Association (USA, Türkiye, Australia, England, India, Israel) and 1127 ORNs participated the study. In multivariate analysis, independent predictors of anxiety and depression status were examined by binary logistic regression analysis. RESULTS: The rate of anxiety is 5.46 times higher in nurses in the USA, 5.07 times higher among nurses in Australia, and 4.49 times higher for nurses in England. It was determined that the rate of depression in ORNs working in Türkiye was 5.97 times higher. It was found that the rate of depression is 1.59 times higher in ORNs living away from the family after care of COVID-19 patient. CONCLUSION: Despite some differences between countries in terms of health system, patient potential, economic and the opportunities offered, generally high levels of anxiety and/or depression indicate that all ORNs need urgent support. Identifying risk factors will help recognize anxiety and depression in ORNs and take measures to protect their mental health during the pandemic.

Long-term Motor and Sensory Outcomes After Unilateral Medial Rectus Recession-Lateral Rectus Resection for Infantile Esotropia.

PURPOSE: To report long-term motor and sensory outcomes after unilateral medial rectus recession-lateral rectus resection for infantile esotropia. METHODS: The medical records of patients who had undergone unilateral medial rectus recession-lateral rectus resection for infantile esotropia and were followed up postoperatively for a minimum of 10 years were reviewed retrospectively. RESULTS: A total of 100 patients were included. The mean age at surgery was 2.9 ± 2.2 years (range: 2.5 months to 9.0 years). The mean postoperative follow-up was 15.7 ± 4.4 years (range:10.0 to 27.5 years). Overall, 54 patients (54%) had surgical success at their last follow-up visit. Age at first surgery, strabismus duration, degree of hyperopia, preoperative size of deviation, presence of dissociated vertical deviation, inferior oblique overaction, or both dissociated vertical deviation and inferior oblique overaction, and the number of esotropia surgeries did not predict motor outcome after surgery. Consecutive exotropia developed in 43% of patients (constant in 18% and intermittent in 25%). Residual and recurrent esotropia occurred in 20% and 21% of patients, respectively. Refractive accommodative esotropia developed in 17% of patients and there was a high accommodation convergence/accommodation ratio esotropia in 2%. Peripheral binocular single vision was achieved in 54% of patients and stereopsis in 1%. Patients with 1.5 years or less of strabismus duration had better chances of achieving peripheral binocular single vision. CONCLUSIONS: Nearly half of the patients with infantile esotropia achieved a successful long-term motor outcome and peripheral binocular single vision. Consecutive exotropia occurred frequently. Recurrent esotropia and refractive accommodative esotropia developed in some patients, and a high accommodation convergence/accommodation ratio esotropia in a few. Stereopsis outcome was extremely poor. [J Pediatr Ophthalmol Strabismus. 2024;61(2):106-113.].

Improved Survival Outcomes with Surgical Resection Compared to Ablative Therapy in Early-Stage HCC: A Large, Real-World, Propensity-Matched, Multi-Centre, Australian Cohort Study.

The optimal treatment approach in very-early and early-stage hepatocellular carcinoma (HCC) is not precisely defined, and there is ambiguity in the literature around the comparative efficacy of surgical resection versus ablation as curative therapies for limited disease. We performed this real-world propensity-matched, multi-centre cohort study to assess for differences in survival outcomes between those undergoing resection and those receiving ablation. Patients with Barcelona Clinic Liver Cancer (BCLC) 0/A HCC first diagnosed between 1 January 2016 and 31 December 2020 who received ablation or resection as initial treatment were included in the study. A total of 450 patients were included in the study from 10 major liver centres including two transplant centres. Following propensity score matching using key covariates, 156 patients were available for analysis with 78 in each group. Patients who underwent resection had significantly improved overall survival (log-rank test p = 0.023) and local recurrence-free survival (log rank test p = 0.027) compared to those who received ablation. Based on real-world data, our study supports the use of surgical resection in preference to ablation as first-line curative therapy in appropriately selected BCLC 0/A HCC patients.

Trace elements dyshomeostasis in liver and brain of weanling mice under altered dietary selenium conditions.

BACKGROUND: A balanced diet containing selenium (Se) and other trace elements is essential for normal development and growth. Se has been recognized as an essential trace element; however, its interaction with other elements has not been fully investigated. In the present study, sodium (Na), magnesium (Mg), potassium (K), calcium (Ca), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), copper (Cu), zinc (Zn), Se and rubidium (Rb), were analysed in liver and brain regions under altered dietary Se intake in weanling mice to identify major discriminatory elements. METHODS: The study investigated the effects of different levels of Se intake on the elemental composition in liver and brain tissues of weaned mice. After 24 weeks of feeding with Se adequate, deficient, and excess diets, elemental analysis was performed on the harvested tissues using Inductively coupled plasma mass spectrometry (ICP-MS). Statistical analysis that included analysis of covariance (ANCOVA), correlation coefficient analysis, principal component analysis, and partial least squares discriminant analysis were performed. RESULTS: The ANCOVA showed statistically significant changes and correlations among the analysed elements under altered dietary Se status. The multivariate analysis showed differential changes in elements in liver and brain regions. The results suggest that long-term dietary Se alternations lead to dyshomeostasis in trace elements that are required in higher concentrations compared to Se. It was observed that changes in the Fe, Co, and Rb levels were similar in all the tissues studied, whereas the changes in Mg, Cr, and Mn levels were different among the tissues under altered dietary Se status. Additionally, the changes in Rb levels correlated with the dietary Se intake but had no relation with the tissue Se levels. CONCLUSIONS: The findings suggest interactions between Mg, Cr, Mn, Fe, Co, and Se under altered Se status may impact cellular functions during postnatal development. However, the possible biological significance of alterations in Rb levels under different dietary Se paradigms needs to be further explored.

The limit of detection of the BioFire® FilmArray® gastrointestinal panel for the foodborne parasite Cyclospora cayetanensis.

Cyclosporiasis is a foodborne diarrheal illness caused by the parasite Cyclospora cayetanensis. The BioFire® FilmArray® gastrointestinal (FilmArray GI) panel is a common method for diagnosing cyclosporiasis from clinical stool samples. The currently published limit of detection (LOD) of this panel is in genome equivalents; however, it is unclear how this relates to the number of C. cayetanensis oocysts in a clinical sample. In this study, we developed a technique to determine the LOD in terms of oocysts, using a cell sorter to sort 1 to 50 C. cayetanensis oocyst(s) previously purified from three human stool sources. We found the FilmArray GI panel detected samples with ≥20 C. cayetanensis oocysts in 100% of replicates, with varying detection among samples with 1, 5, or 10 C. cayetanensis oocysts. This method provides a parasitologically relevant LOD that should enable comparison among C. cayetanensis detection techniques, including the FilmArray GI panel.

The Prevalence of Comorbidities and Associated Factors among Patients with Dementia in the Indian Setting: Meta-analysis of Observational Studies.

Background: Patients with dementia usually have multiple comorbidities. The presence of comorbidities may exacerbate the progression of dementia and decreases the patient's ability to participate in health maintenance activities. However, there is hardly any meta-analysis estimating the magnitude of comorbidities among patients with dementia in the Indian context. Methods: We searched PubMed, Scopus, and Google Scholar, and relevant studies conducted in India were included. The risk of bias was assessed and a random-effects meta-analysis model was used in which I2 statistics were calculated to measure heterogeneity among studies. Results: Fourteen studies were included in the meta-analysis based on the inclusion and exclusion criteria. Altogether, we found the coexistence of comorbid conditions such as hypertension (51.10%), diabetes (27.58%), stroke (15.99%), and factors like tobacco use (26.81 %) and alcohol use (9.19%) among patients with dementia in this setting. The level of heterogeneity was high due to differences in the methodologies in the included studies. Conclusions: Our study found hypertension as the most common comorbid condition among patients with dementia in India. The observed lacuna of methodological limitations in the studies included in the current meta-analysis provides the urgent need for good quality research to successfully meet the challenges ahead while devising appropriate strategies to treat the comorbidities among patients with dementia.

Comparative effectiveness of six herbs in the management of glycemic status of type 2 diabetes mellitus patients: A systematic review and network meta-analysis of randomized controlled trials.

BACKGROUND AND AIMS: There are several herbal formulations for type 2 diabetes (T2D), but many of them have never been directly compared to establish the most effective methods. Therefore, the present systematic review and network meta-analysis aimed to compare and rank the effects of herbal formulations by combining direct and indirect evidence on the management of type 2 diabetes. METHODS: From five electronic databases, relevant studies on the effectiveness of herbal formulations for glycemic status for people with type 2 diabetes were retrieved. Only randomized controlled trials that were published in English and looked at how herbal formulations affected adults' (>18-year-old) glycemic levels were included. A systematic review and network meta-analysis design with the random-effects model was used. RESULTS: A total of 44 trials included 3130 participants on six herbs were included in the final analysis. Apple cider vinegar (ACV) (standardized mean difference (SMD) = -28.99), cinnamon (-9.73), curcumin (-13.15), and fenugreek (-19.64) significantly reduced fasting blood glucose (FBG) compared with placebo (all p < 0.05). Notably, only ACV (SMD = -2.10) and fenugreek seeds (0.84) were found significantly effective in reducing HbA1C. ACV was most effective herb to reduce FBG comparison with other herbs. CONCLUSIONS: Several herbs could be considered as a valuable adjuvant therapy regarding glycemic control of type 2 diabetes patients. Health professionals should be encouraged to incorporate these herbs for the management of type 2 diabetes as part of their standard care.

Perception, perceived scope, and potential barriers towards developing nurse practitioners cadre among health care providers and beneficiaries: A pilot study from Northern India.

BACKGROUND: The role of nurse practitioner (NP) emerged in early 1965 when general practitioners began working with nurses. Evidence across the world highlights the benefits achieved by the NP role. The Indian Nursing Council (INC) implemented a country-wide NP in critical care (NPCC) program with the approval of the ministry of health and family welfare (MoHFW) in 2017. The NP role is in its infancy in India. Hence, there is a need to assess the perception among beneficiaries and healthcare personnel. This study was conducted to assess the perception, perceived scope, and potential barriers for developing the role of NPs in India among beneficiaries and healthcare providers. MATERIAL AND METHODS: A descriptive, cross-sectional pilot study was conducted at AIIMS Rishikesh, Uttarakhand, India, among 205 participants (84 beneficiaries, 78 nurses, and 43 physicians) using a proportionate stratified random sampling technique. Likert scales and socio-demographic sheets were used to assess the perception, perceived scope of practice, and potential barriers in developing a NP cadre in India. Descriptive and inferential statistics were used for analyzing data. RESULTS: The mean age of beneficiaries was 37.98, nurses was 27.58, and physicians was 28.13 years, respectively. 121 (61%) of participants were highly favored, and 77 (38%) were in favor of developing NP cadre in India. They considered it to be necessary, feasible, and acceptable in India. The feasibility and necessity of the perception domain were highly significant (P < 0.001 and P < 0.003, respectively). Nurses (mean ± SD: 35.36 ± 3.55) considered that NPs could have a wide range of practice followed by beneficiaries (mean ± SD: 38.17 ± 3.68) than physicians (mean ± SD: 34.75 ± 5.95). Lack of awareness, the nonexistence of cadre structure, lack of acceptance of the role of physicians, and lack of clear policy were the key potential barriers to develop an NP cadre in India. CONCLUSIONS: In this study, participants had favorable views on employing NPs in India; thus, this role will improve healthcare access for beneficiaries. NPs can carry out a wide range of practices.However, a lack of awareness, no cadre structure, and a lack of a clear policy may hinder the development of the NP cadre in India.

The development and randomised feasibility trial of a Nurse-led lifestyle modification follow-up programme among post-myocardial infarction patients.

Background: Cardiovascular disease is the most often occurring disease in India accounting for 24.8% of deaths. Myocardial infarction contributes to this. A higher risk of cardiovascular disease exists due to comorbidities or the unawareness of existing illness among the Indian population. There is a shortage of published research on cardiovascular disease and a lack of standard cardiac rehabilitation programmes in India. Aim: Our study aims to develop a Nurse-led lifestyle modification follow-up programme, to assess and compare the effectiveness of the programme on health outcomes and quality of life among post-myocardial infarction patients. Methods: A two arm, single-blinded, randomised feasibility trial was conducted by developing a Nurse-led lifestyle modification follow-up programme. The interventional programme was based on the information-motivation-behavioural skill model and included health education, an educational booklet, and telephone follow-up. For feasibility testing of intervention, 12 patients were randomly allocated (n = 6/group). Patients in the control group were provided with routine care, while the intervention group was given routine care along with a Nurse-led lifestyle modification follow-up programme. Results: It was possible to use this tool. In addition to determining the tool's feasibility for use we found that the intervention group showed a significant improvement in systolic blood pressure (BP) (p = 0.001), diastolic BP (p = 0.016), Body Mass Index (BMI) (p = 0.004), and quality of life in all the subscales - physical, emotional and social (p < 0.001) after 12 weeks of discharge. Conclusion: Findings from this study will help to reinforce designing a cost-effective care delivery system in the care of post-myocardial infarction patients. This programme is a novel approach to improve preventive, curative and rehabilitative services for the post-myocardial infarction patients in India.

An Unusual Case of Telangiectasias.

BACKGROUND: Telengiectasias are defined as persistent dilatation of small capillaries in the superficial dermis Case : A 26-year-old woman presented with red lesions, epistaxis, joint pains, color changes of the hands, and breathlessness. On clinical examination and investigations, a final diagnosis of mixed connective tissue disease (MCTD), with interstitial lung disease (ILD), with telangiectasias, and epistaxis was made. Telangiectasias and epistaxis are rare presentations of MCTD.

Effect of Intermittent Fasting on Glycaemic Control in Patients With Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: Type 2 diabetes mellitus (T2DM) is a severe public health issue notably impacting human life and health expenditure. It has been observed in literature that intermittent fasting (IF) addresses diabetes and its underlying cause, which benefits people with diabetes. Therefore, this study aimed to evaluate the effectiveness of IF treatment on glycaemic control in people with T2DM compared with control group. Methods: Systematic review and meta-analysis of interventional studies among patients with T2DM with glycated haemoglobin (HbA1c) as an outcome was performed. A comprehensive search of electronic databases, including PubMed, Embase and Google Scholar, for articles published before 24 April 2022, was done. Studies reporting 24 hours of complete fasting or intermittent restricted energy intake (feeding permitted for only 4-8 hours daily, with 16-20 hours of fasting) and reporting changes in HbA1c and fasting glucose levels were eligible. Meta-analysis was performed using Cochrane's Q statistic and the I2 statistical approach. Results: Eleven studies (13 arms) measuring the effect of IF on patients' HbA1c level were analysed. There was no statistically significant difference between IF and control groups (Standardized mean difference [SMD] -0.08, 95% confidence interval [CI] -0.20 to 0.04;p=0.19, I2=22%). Overall, seven studies on patients' fasting blood glucose were analysed, and the meta-analysis revealed no significant difference between the two groups i.e. IF and control groups (SMD 0.06, 95% CI -0.25 to 0.38;p=0.69, I2=76%). Conclusion: IF and usual diet pattern have no difference in terms of glycaemic control. Although, IF may be used as a preventative diet pattern in the pre-diabetic population, as it works well in the long-term to achieve controlled sugar levels. Study registration: The protocol of this study was registered in The International Prospective Register of Systematic Reviews (PROSPERO) with a registration number CRD42022328528.

The Distribution of Lifestyle Risk Factors Among Patients with Stroke in the Indian Setting: Systematic Review and Meta-Analysis.

Background: The burden of stroke is increasing in India, but there is limited understanding of the distribution of reported risk factors in the Indian setting. It is vital to generate robust data on these modifiable risk factors to scale up appropriate strategies for the prevention of cerebrovascular diseases in this setting. Summary: The objective of this study is to estimate the overall proportion of life style risk factors of patients with stroke in the Indian setting. We searched PubMed and Google Scholar and relevant studies published till February 2022 were included. The risk of bias assessment was considered for the study selection criterion in the meta-analysis. The publication bias was evaluated by funnel plots and Egger's test. We identified 61 studies in the systematic review and after quality assessment, 36 studies were included for meta-analysis. Random effect model was used due to the significant inconsistency among the included studies (I2 > 97%). The mean age of the participants was 53.84±9.3 years and patients with stroke were predominantly males (64%). Hypertension (56.69%; 95% CI: - 48.45 - 64.58), obesity (36.61%; 95% CI: - 19.31 - 58.23), dyslipidemia (30.6%; 95% CI: - 22 - 40.81) and diabetes mellitus (23.8%; 95% CI: - 18.79 - 29.83) are the leading intermediate conditions associated with stroke. The Physical inactivity - 29.9% (95% CI: - 22.9 - 37.1), history of tobacco use (28.59 %; 95% CI: - 22.22 - 32.94) and alcohol use (28.15 %; 95% CI: - 20.49 - 37.33) were reported as the behavioral risk factors for stroke in this setting. Key Messages: The current meta-analysis provides robust estimates of the life style related risk-factor of stroke in India based on the observational studies conducted from 1994 to 2019. Estimating the pooled analysis of stroke risk factors is crucial to predict the imposed burden of the illness and ascertain the treatment and prevention strategies for controlling the modifiable risk factors in this setting.

Contact Lens Use Advice-Risks and Outcomes: Are Patients Drowning in Information but Starved for Knowledge?

Objectives: Microbial keratitis can cause significant visual morbidity and is a common reason for presentation to eye casualty clinics. Contact lens wear and poor contact lens hygiene significantly increase the risk of corneal infection. This study aimed to determine the level of contact lens hygiene awareness amongst contact lens wearers attending our service and determining whether contact lens type and hygiene attitude are related to severity of disease. Materials and Methods: This prospective questionnaire-based study included 50 consecutive patients attending the eye casualty clinic of a tertiary referral center. Visual acuity was assessed at presentation and 2 weeks after diagnosis. Patients were divided into subgroups according to contact lens type (monthly, bi-weekly, daily, and extended day and night wear) and risk group (low, medium, and high) depending on their contact lens hygiene practices. Results: Thirty-four women and 16 men were included in this study. Twenty-four patients used monthly disposable contact lenses, 16 used daily disposable contact lenses, 6 were using bi-weekly replacement lenses, and 4 patients were using extended wear (day and night) contact lenses. Twenty-five patients were diagnosed with corneal ulcer, 23 of which had some degree of poor contact lens hygiene. Best corrected visual acuity (BCVA) significantly improved after treatment. Mean BCVA was 0.24 LogMAR before treatment and 0.09 LogMAR after treatment (p<0.05). Conclusion: Our study highlights the need to improve contact lens hygiene awareness and influence hygiene practices. Patients with the poorest contact lens hygiene had slower visual recovery and a higher prevalence of corneal ulcer. Contact lens hygiene advice needs to be clear and reinforced over time.

Musculoskeletal disorders among doctors and nursing officers : an occupational hazard of overstrained healthcare delivery system in western Rajasthan, India.

BACKGROUND: The present study was conducted to estimate the prevalence and distribution of MSDs in different anatomical regions among Doctors and NO and to determine their ergonomic risk factors and predictors. METHODS: This cross-sectional study was conducted in an apex institution in Western India. The socio-demographic information, medical and occupational history, and other personal and work-related attributes were captured using a semi-structured questionnaire, which was developed and finalized by piloting on 32 participants (who were not part of the study). Nordic Musculoskeletal and International Physical Activity Questionnaires were used to assess MSDs and Physical activity. Data were analyzed using SPSS v.23. Prevalence of Musculoskeletal Symptoms (M.S.), Multisite Musculoskeletal Symptoms (MMS), and Widespread Musculoskeletal Symptoms (WMS) were calculated. A comparison was made to estimate the burden and distribution of MSD among Doctors and Nursing officers. Logistic regression was applied to identify the predictors of MSDs and pinpoint the risk factors associated with MSDs. RESULTS: A total of 310 participants, of which 38.7% were doctors, and 61.3% were Nursing Officers (NOs) were included in the study. The mean age of the respondents was 31.63 ± 4.9 years. Almost 73% (95%CI: 67.9-78.1) of participants had MSD in the last 12 months, with approximately 41.6% (95%CI: 36.1-47.3) suffering from MSDs in the previous seven days of the survey. The lower back (49.7%) and the neck (36.5%) were the most affected sites. Working in the same position for a long time (43.5%) and not taking adequate breaks (31.3%) were the highest self-reported risk factors. Females had significantly higher odds of having pain in the upper back [aOR:2.49(1.27-4.85)], neck [aOR:2.15(1.22-3.77)], shoulder [aOR:2.8 (1.54-5.11)], hips [aOR:9.46 (3.95-22.68)] and knee [aOR:3.8(1.99-7.26)]. CONCLUSIONS: Females, who are NOs, work for > 48 h per week, and fall in the obese category were significantly at more risk of developing MSDs. Working in an awkward position, treating an excessive number of patients in a day, working in the same position for a long period, performing repeated tasks, and not having enough rest breaks were significant risk factors for MSDs.

Effect of Electromagnetic Radiation from Mobile Phones on Auditory Brainstem Response.

Mobile phones are being used by around 70% of the global population. A simple non-invasive procedure to detect early impairment of the acoustic nerve and auditory pathway is by auditory brainstem response (ABR). It's a response to the sound stimulus generated from the brainstem in the form of electrical impulses. To determine the effect of long-term usage of mobile phones on auditory brainstem responses (ABRs). This Epidemiological, cross-sectional study was undertaken at a tertiary care hospital and includes 865 individuals aged between 18 to 45 years using mobile phone for > 2 years. Users were categorized into various groups according to the minutes of mobile usage per day, years of mobile usage and total duration of mobile phone use in dominant (mobile using) and non-Dominant (non-mobile using) ears. The changes in ABR were studied in each ear to ascertain the effect of EMF exposure due to chronic mobile phone use. Mean age of subjects was 27.01 years. (M: F = 1.57:1.0). Range of mobile phone usage was from 4 to 900 min/day, with mean as 85.94 min/day. No significant differences were seen between dominant and non-dominant ears in regard to amplitudes of wave I, III and V, latencies of wave I and V and Inter peak latency (IPL) of wave I-III, III-V and I-V. No statistically significant difference for I-III, III-V and I-V IPL were found b/w two groups/ears except for usage of mobile phone for > 180 min/day in wave I-V, usage for 0-4 years in wave I-III and I-V and net hours usage for > 1500 h in wave I-V. The mean IPL in all the waves increases with the increase in years of mobile usage and is maximum in all waves in > 12 years mobile users. The long-term exposure to EMF does induce measurable changes in ABRs. Amplitude and IPLs of ABR were found comparable between the dominant and non-dominant ears using mobile phones, except for those using mobile usage for > 180 min/day and with increasing years of usage of mobile phone. Therefore, prudent use of mobile phone should be encouraged for a shorter period of time and for essential purpose only.

Economic Evaluation of Nucleic Acid Testing for Screening of Blood Donations for Thalassemia Patients (ECONAT) in Western India.

Background: Transfusion Transmitted infections(TTI) are of significant concern for blood safety. The thalassemia patients who receive multiple transfusions are at an increased risk of TTIs and the Nucleic Acid Test (NAT ) has been advocated for safe blood. Though NAT can reduce the window period compared to serology, cost is a constraint. Methods: The thalassemia patient and NAT yield data from the centralized NAT lab in AIIMS Jodhpur was evaluated for cost-effectiveness using the Markov model. The incremental cost-effectiveness ratio (ICER) was calculated by dividing the difference between the cost for NAT and the cost of medical management of TTI-related complications by the product of the difference in utility value of a TTI health state with time and Gross National Income(GNI) per capita. Results: Out of the 48,762 samples tested by NAT, 43 samples were discriminated NAT yield all of which were reactive for Hepatitis B (NAT yield of 1:1134). There was no HCV and HIV NAT yield despite HCV being the most prevalent TTI in this population. The cost of this intervention was INR 5,85,14,400. The number of lifetime QALY saved was 1.38 years. The cost of medical management is INR 82,19,114. Therefore the ICER for intervention is INR 3,64,45,860 per QALY saved which is 274 times the GNI per capita of India. Conclusions: The provision of IDNAT-tested blood for thalassemia patients in Rajasthan state was not found to be cost-effective. Measures to bring down the cost or alternative options to increase blood safety should be explored.

Over Expression of Cancer Stem Cell Marker CD44 and Its Clinical Significance in Patients with Oral Squamous Cell Carcinoma.

Cancer stem cell marker CD44 is a cell-surface glycoprotein which is involved in various cellular functions such as cell-cell interactions, cell adhesion, haematopoiesis and tumour metastasis. The CD44 gene transcription is partly activated by beta-catenin and Wnt signalling pathway, the later pathway being linked to tumour development. However, the role of CD44 in oral squamous cell carcinoma (OSCC) is not well understood. We investigated the expression of CD44 in peripheral circulation, tumour tissues of oral cancer patients and oral squamous cell carcinoma cell lines by ELISA and quantitative (q)-RTPCR. Relative CD44s mRNA expression was significantly higher in peripheral circulation (p = 0.04), tumour tissues (p = 0.049) and in oral cancer cell lines (SCC4, SCC25 p = 0.02, SCC9 p = 0.03). Circulating CD44total protein levels were also significantly (p < 0.001) higher in OSCC patients that positively correlated with increasing tumour load and loco-regional spread of the tumour. The circulating tumour stem cell marker CD44 appears to be a potent indicator of tumour progression and may be useful for developing suitable therapeutics strategies for patients with oral squamous cell carcinoma.
