The clinical demand and supply of blood in India: A National level estimation study
(2022) Lakshmanan, Jeyaseelan
Background: Estimating the clinical demand for blood and components arising in a health facility is crucial to ensure timely availability of blood. This study aims to estimate disease-specific clinical demand, supply and utilization of whole blood and components in India. Methods: We conducted a national level cross-sectional study in five randomly selected states from five regions of the country. We included 251 public and private facilities representing primary, secondary and tertiary care facilities. We collected annual disease-specific demand, supply and utilization of blood and components using a structured tool. We estimated the national demand by extrapolating the study data (demand and beds) to the total number of estimated beds in the country. Findings: According to the study, the total clinical demand of 251 health facilities with 51,562 beds was 474,627 whole blood units. Based on this, the clinical demand for India was estimated at 14.6 million whole blood units (95 CI: 14.59–14.62), an equivalent of 36.3 donations per 1,000 eligible populations, which will address whole blood and component requirement. The medicine specialty accounted for 6.0 million units (41.2%), followed by surgery 4.1 million (27.9%), obstetrics and gynecology 3.3 million (22.4%) and pediatrics 1.2 million (8.5%) units. The supply was 93% which is equivalent to 33.8 donations against the demand. Conclusion: The study indicated a demand and supply gap of 2.5 donations per 1,000 eligible persons which is around one million units. The gap emphasises the need for sustained and concerted efforts from all stakeholders and for increasing the awareness about repeat voluntary non-remunerated blood donation (VNRBD); optimizing the availability of blood components through efficient blood component separation units; promoting modern principles of patient blood management and strengthening capacities of human resources in the blood transfusion system in India.

(2023) Benamer, Hani TS; Alsuwaidi, Laila; Khan, Nusrat; Lakshmanan, Jeyaseelan; Ho, Samuel B.; Kellett, Catherine; Alsheikh-Ali, Alawi; Stanley, Adrian G
Background: The clinical placements of our medical students are almost equally distributed across private and public sectors. This study aims to assess medical students’ perceptions of their Clinical learning Environment (CLE) across these two different healthcare settings, using the Undergraduate Clinical Education Environment Measure (UCEEM). Methods: 76 undergraduate medical students (Year 5 and 6), were invited to participate. Data were collected using an online UCEEM with additional questions related to demographics and case load exposure. The UCEEM consists of two overarching domains of experiential learning and social participation, with four subdomains of learning opportunities, preparedness, workplace interaction, and inclusion. Results: 38 questionnaires were received. Of 225 responses to the individual UCEEM items, 51 (22.6%) scored a mean of ≥4 (range 4-4.5, representing strong areas), 31 (13.7%) scored a mean of ≤3 (range 2.1-3, needing attention) and 143 (63.6%) scored a mean of 3.1–3.9 (areas that could be improved). The majority (63%) of the case load exposure responses scored a mean of ≥4 (range 4-4.5). Compared to the private sittings, there is a significant reduction in total UCEEM (p=0.008), preparedness for student entry (p=0.003), and overarching dimension of social participation (p=0.000) scores for the public sector. Similarly, both workplace interaction patterns and student inclusion and equal treatment scored significantly lower for the public sector (p=0.000 and p=0.011 respectively). Two out of three case load exposure items scored significantly higher for the public sector (p=0.000). Discussion: The students’ CLE perceptions were generally positive. The lower UCEEM ratings in the public sector items were related to student entry preparedness, workplace interactions, student inclusiveness and workforce equity of treatment. In contrast the students were exposed to more variety and larger number of patients in the public sector. These differences indicated some significantly different learning environments between the two sectors.
COVID-19 Case Management Outcomes Amongst Diabetes and Hypertensive Patients in the United Arab Emirates: A Prospective Study
(2022-11) Al Zaabi, Shaikha; Lakshmanan, Jeyaseelan
Abstract: The global pandemic of the novel Coronavirus infection 2019 (COVID-19) challenged the care of comorbid patients. The risk imposed by COVID-19 on diabetes patients is multisystemic, exponential, and involves glucose dysregulation. The increased burden for diabetes patients infected with COVID-19 is substantial in countries with a high prevalence of diabetics, such as the United Arab Emirates (UAE). This study aims to explore the prevalence of diabetes, clinical characteristic, and outcomes of patients admitted for COVID-19 treatment with or without a concurrent preadmission diagnosis of diabetes. A prospective study was performed on 1199 adults admitted with confirmed COVID-19 from December 2020 to April 2021 to a single hospital in the UAE. The study compared the demographics, clinical characteristics, and outcomes in COVID-19-infected patients with diabetes to patients without diabetes. The study endpoints include the development of new-onset diabetes, admission to ICU, trends in the blood glucose levels, and death. A total of 1199 patients (390 with diabetes) were included in the study. A diabetes prevalence was detected among 9.8% of the study population. Among the diabetes group, 10.8% were morbidly obese, 65.4% had associated hypertension, and 18.9% had coronary artery disease. Diabetes patients showed higher rates of ICU admission (11.1% vs. 7.1%), NIV requirement (9.6% vs. 6.4%), and intubation (5.45% vs. 2%) compared to the non-diabetes group. Advanced age was a predictor of a worsening COVID-19 course, while diabetes (p < 0.050) and hypertension (p < 0.025) were significant predictors of death from COVID-19. Nearly three-fourths (284 (73.4%)) of the diabetic patients developed worsened hyperglycemia as compared to one-fifth (171 (20.9%)) of the nondiabetic patients. New-onset diabetes was detected in 9.8% of COVID-19 patients. COVID-19 severity is higher in the presence of diabetes and is associated with worsening hyperglycemia and poor clinical outcomes. Preexisting hypertension is a predictor of COVID-19 severity and death.

(2023) Albanna, Ammar; Alhashmi, Deena; Lakshmanan, Jeyaseelan
Background: Attention deficit hyperactivity disorder is a common neurodevelopmental disorder. Accessing services for this disorder is a worldwide challenge and requires innovative interventions. Aims: We aimed to investigate the effectiveness of tele-collaborative care for attention deficit hyperactivity disorder in primary health care centres in Dubai. Methods: Six trained physicians started collaborative care clinics across Dubai. Eligible children aged 6–12 years attending primary health care centres with attention deficit hyperactivity disorder were randomly selected to receive telehealth collaborative care, or standard treatment. Baseline assessments were conducted using the Vanderbilt Behavioral Assessment Scale, the Columbia Impairment Scale, the Childhood Behavior Checklist, and the Strength and Difficulties Questionnaire. Waiting times and clinical and functional outcomes were measured in both groups and compared. Continuous variables were presented as means and standard deviations, categorical variables such as sex were presented as numbers and percentages, and continuous outcome variables were compared using the Student t-test. Results: Among the referred children (n = 112), 11 boys and 6 girls met the eligibility criteria (mean age 7.8 years). The dropout rate at 6 months in the control group was 80%, compared with 50% in the intervention group. The mean waiting time was significantly shorter in the intervention group (1.3 weeks) than the control group (7.1 weeks); P = 0.026. The mean difference in the Childhood Behavior Checklist total score over time was significantly higher in the intervention group (P = 0.042), but the mean difference in the Vanderbilt scale was not significant. Conclusion: Tele-collaborative care for children with attention deficit hyperactivity disorder within primary health care is feasible.
A novel reconstructive approach of the lumbar vertebral column from 2D MRI to 3D models
(2022-11) Naidoo, Nerissa; Lakshmanan, Jeyaseelan; Prithishkumar, Ivan James
Introduction: Low back pain (LBP), arising from the lumbar vertebral column (LVC), is a global burden, ranking highest in terms of disability. In the United Arab Emirates (UAE), there is a high prevalence of LBP in the adult population. As MRI has emerged as the mainstay in assessment of LVC-related conditions, this study aimed to reconstruct reproducible 3D LVC MRI models from 2D MRI scans. Methods: Following the extraction of serial 2D MRI scan slices from an existing image database, ffty 3D MRI models (n = 50) were retrospectively reconstructed (Mimics Innovation Suite ®) and analyzed through the bootstrapping technique. Results: Lumbar vertebral bodies depicted kidney and oval shapes, with an increasing frequency of the former traced from L1 to L5. Traction (10%) and claw (14%) osteophyte types were noted. The inferior rims of L2 (2%) and L4 (4%) presented with the co-existence of both osteophyte types, which was reflective of the same degenerative process. Morphometric dimensions of L1 were also determined: Anterior vertebral height: 29.6 ± 3.5 mm (28.6–30.5 mm); Posterior vertebral height: 26.8 ± 3.1 mm (25.9–29.6 mm); Superior vertebral width: 40.6 ± 3.8 mm (39.6–41.6 mm); Intervertebral disc height between L1 and L2: 15.9 ± 6.3 mm (14.3–17.7 mm). Conclusion: A proof-of-concept in the reconstructive approach of the LVC was established, which introduces a process through which a normative simulated dataset can be obtained in the extended population. Additionally, these values will assist to detect structural disproportions and changes and contribute to pre-operative planning and artificial intervertebral disc implant design.
Prevalence and Factors Affecting Difficult Intravenous Access in Children in Oman: A Cross-sectional Study
(2022-07) Lakshmanan, Jeyaseelan
Abstract: Objectives: Peripheral intravenous (IV) access is a standard procedure in clinical settings. Nevertheless, previous studies have indicated that difficult peripheral IV access is prevalent in children. This study aimed to determine the prevalence and factors contributing to difficult peripheral IV cannulation in children admitted to a tertiary care hospital in Oman. Methods: This cross-sectional study was conducted from September to December 2015 at Sultan Qaboos University Hospital in Muscat, Oman. Nurses collected data concerning factors contributing to difficult IV access in children. Results: A total of 511 children undergoing cannulation during the study period were included in the analysis. Overall, 23.3% of the children experienced two or more cannulation attempts. The study identified three variables associated with successful cannulation in cases of difficult IV access. Visible veins were 2.72-times (95% CI: 1.58–4.68) more likely to be associated with success (p < 0.001), while palpable veins were 2.22-times (95% CI: 1.29–3.83) more likely to be associated with success (p = 0.004). However, scarring from previous IV access attempts was half (95% CI: 0.31–0.77) as likely to be associated with successful cannulation (p = 0.002). Conclusions: We identified statistically significant variables related to difficult IV cannulation in children, which we used to develop a prediction tool to assess the likelihood of difficult IV access in pediatric patients. Further research is necessary to validate the use of the difficult IV access prediction tool in this population.
Prolonged corrected QT interval in hospitalized patients with coronavirus disease 2019 in Dubai, United Arab Emirates: a single-center, retrospective study.
(2021) Lakshmanan, Jeyaseelan
Objective: To evaluate the association of a prolonged corrected QT (QTc) interval in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and its association with in-patient mortality. Methods: A cohort of 745 patients were recruited from a single center between 1 March 2020 and 31 May 2020. We analyzed the factors associated with a prolonged QTc and mortality. Results: A prolonged QTc interval >450 ms was found in 27% of patients admitted with SARS-CoV-2 infection. These patients were predominantly older, on a ventilator, and had hypertension, diabetes mellitus, or ischemic heart disease. They also had high troponin and D-dimer concentrations. A prolonged QTc interval had a significant association with the requirement of ventilator support and was associated with an increased odds of mortality. Patients who died were older than 55 years, and had high troponin, D-dimer, creatinine, procalcitonin, and ferritin concentrations, a high white blood cell count, and abnormal potassium concentrations (hypo- or hyperkalemia). Conclusions: A prolonged QTc interval is common in patients with SARS-CoV-2 infection and it is associated with worse outcomes. Older individuals and those with comorbidities should have an electrocardiogram performed, which is noninvasive and easily available, on admission to hospital to identify high-risk patients.
Rezum Therapy for Benign Prostatic Hyperplasia: Dubai’s Initial Experience
(2021) Rowaiee, Rashed; Akhras, Aya; Lakshmanan, Jeyaseelan; Janahi, Farhad
Introduction: Symptomatic benign prostatic hyperplasia (BPH) is a condition that affects middle-aged men, leading to a decreased quality of life secondary to symptoms of difficult urination, urinary frequency, urgency and nocturia. The treatment modalities of this pathology include pharmacologic and invasive interventions, both of which vary in effectiveness and they come with a myriad of side effects. Recent advancements have allowed for the development of Rezum, a minimally invasive and effective approach to treating BPH while maintaining a good safety profile with comparable outcomes to other treatment modalities. Methods: We retrospectively identified 49 patients with symptomatic BPH who underwent Rezum therapy in one center in Dubai, the United Arab Emirates between January and December 2020. We assessed several parameters related to their condition including prostate volume, pre-operative and post-operative post-void residual (PVR) and peak urinary flow (Qmax) number of treatments given, trial without catheter and mean date of follow-up. Safety and side effects were also assessed. Result: Our sample included symptomatic men with a mean age of 64 (10) who had a mean follow-up time of three months (IQR 2-5.2), median prostatic volume of 58 cc (IQR 44-82) and a mean of (SD 33.9). The initial Qmax and PVR were 7.3 ml/s (IQR 5.5-10.3) and 80.4 cm3 (IQR 43.4-120.0) respectively, and post-operative Qmax and PVR were 16.3 ml/s (SD 5.7) and 20.7 cm3 (IQR 16.2-28.2). Post-operatively, we observed a significant increase in Qmax of 8.11 ml/s (p=0.001) post-operatively, a mean decrease of 94.32 cm3 (p=0.001) in PVR. The favorable outcome parameters in Qmax and PVR demonstrate the efficacy of this procedure. We have also noted that the change in Qmax and PVR does not vary by initial prostate volume. Conclusion In this report, we aimed to highlight the benefit, efficacy and safety of offering Rezum to patients with symptomatic BPH in a single center in Dubai, reporting on the first United Arab Emirates experience with this novel procedure. This procedure confers the benefit of being minimally invasive, safe and effective, and with lower rates of sexual dysfunction compared to medical therapy or trans-urethral resection of the prostate (TURP). It is associated with similar outcomes to TURP, and an improvement in quality of life, while carrying a low-risk profile. Our experience corresponds with the available literature regarding the efficacy and satisfaction rates of Rezum for BPH patients. We hope that results from this study encourage further investigation into the long-term implications of Rezum, up to five years post-operatively.
Utility of oral glucose tolerance test in predicting type 2 diabetes following gestational diabetes: Towards personalized care
(2021) Hassan Khamis, Amar; Lakshmanan, Jeyaseelan; Bayoumi, Riad
Background: Women with gestational diabetes mellitus (GDM) are at a seven-fold higher risk of developing type 2 diabetes (T2D) within 7-10 years after childbirth, compared with those with normoglycemic pregnancy. Although raised fasting blood glucose (FBG) levels has been said to be the main significant predictor of postpartum progression to T2D, it is difficult to predict who among the women with GDM would develop T2D. Therefore, we conducted a cross-sectional retrospective study to examine the glycemic indices that can predict postnatal T2D in Emirati Arab women with a history of GDM. Aim: To assess how oral glucose tolerance test (OGTT) can identify the distinct GDM pathophysiology and predict possible distinct postnatal T2D subtypes. Methods: The glycemic status of a cohort of 4603 pregnant Emirati Arab women, who delivered in 2007 at both Latifa Women and Children Hospital and at Dubai Hospital, United Arab Emirates, was assessed retrospectively, using the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria. Of the total, 1231 women were followed up and assessed in 2016. The FBG and/or the 2-h blood glucose (2hrBG) levels after a 75-g glucose load were measured to assess the prevalence of GDM and T2D, according to the IADPSG and American Diabetes Association (ADA) criteria, respectively. The receiver operating characteristic curve for the OGTT was plotted and sensitivity, specificity, and predictive values of FBG and 2hrBG for T2D were determined. Results: Considering both FBG and 2hrBG levels, according to the IADPSG criteria, the prevalence of GDM in pregnant Emirati women in 2007 was 1057/4603 (23%), while the prevalence of pre-pregnancy T2D among them, based on ADA criteria, was 230/4603 (5%). In the subset of women (n = 1231) followed up in 2016, the prevalence of GDM in 2007 was 362/1231 (29.6%), while the prevalence of prepregnancy T2D was 36/1231 (2.9%). Of the 362 pregnant women with GDM in 2007, 96/362 (26.5%) developed T2D; 142/362 (39.2%) developed impaired fasting glucose; 29/362 (8.0%) developed impaired glucose tolerance, and the remaining 95/362 (26.2%) had normal glycemia in 2016. The prevalence of T2D, based on ADA criteria, stemmed from the prevalence of 36/1231 (2.9%) in 2007 to 141/1231 (11.5%), in 2016. The positive predictive value (PPV) for FBG suggests that if a woman tested positive for GDM in 2007, the probability of developing T2D in 2016 was approximately 24%. The opposite was observed when 2hrBG was used for diagnosis. The PPV value for 2hrBG suggests that if a woman was positive for GDM in 2007 then the probability of developing T2D in 2016 was only 3%. Conclusion: FBG and 2hrBG could predict postpartum T2D, following antenatal GDM. However, each test reflects different pathophysiology and possible T2D subtype and could be matched with a relevant T2D prevention program.
