Interactome based identification and validation of prefoldin 5-α for prognosing CNS leukemia in B-ALL patients.

We report here the identification and validation of prefoldin 5-alpha (PFDN5-α) for the first time as prognostic biomarker for prediction of central nervous system (CNS) leukemia of B cell acute lymphoblastic leukemia (B-ALL) origin. Since cerebrospinal fluid (CSF) cytology being the gold standard of diagnosis for CNS leukemia with poor sensitivity, mandatory prophylactic intrathecal chemotherapy is administered irrespective of patients develop CNS leukemia. Thus, using interactome studies, we identified PFDN5-α as a prognostic biomarker for predicting CNS leukemia by interacting lymphoblastic proteins and CSF from B-ALL patients using far-western clinical proteomics approach. Validation by both western and ELISA methods confirmed our results. For further clinical translation, we performed Receiver Operating Characteristic (ROC) curve analysis generated from CNS +ve (n = 25) and -ve (n = 40) CSF samples from B-ALL patients and identified PFDN5-α-CSF reactivity cut-off value as 0.456. Values below 0.456 indicate the patient is at risk of developing CNS leukemia and suggestive of having intrathecal chemotherapy. Further flow cytometry validation for CNS leukemia positivity revealed that with increasing blast cells, a decrease in PFDN5-α-CSF reactivity confirming ELISA based PFDN5α-CSF reactivity assay. Predicting CNS leukemia development risk by ELISA based PFDN5-α-CSF reactivity assay could have potential in the clinical management of CNS leukemia.

Psycho-physio-biochemical modulations brought by Integrated Amrita Meditation (IAM®) relieved stress and improved glycemic control in type 2 diabetic subjects.

Background and objectives: In type 2 diabetic subjects, psychological stress worsens glycemic regulation. This study put forward the various psychophysiological and biochemical benefits of the Integrated Amrita Meditation (IAM®) technique in type 2 diabetic subjects in achieving a better quality of life. Methods: This was a clinical trial conducted in the Endocrinology department of Amrita Institute of Medical Sciences. 85 type 2 diabetic subjects between the age group of 30-65 years were recruited for the study. They were randomly allocated to IAM (n = 43) and the control group (n = 42). All the physiological, biochemical, and psychological variables were assessed at baseline, 3 months, and 6 months. Results: Within the experimental group there was statistically significant reduction in heart rate, respiratory rate, blood pressure, fasting blood glucose, HbA1c, insulin and insulin resistance (p < 0.05). The average percentage changes of these variables between the groups were also significant. HDL showed an increase within the IAM®group (p < 0.001) while there was an increase in LDL and total cholesterol in the control group. Between the groups, the mean percentage changes in stress hormones cortisol and adrenaline were also significant. IgA (p = 0.002) and GABA (p = 0.007) significantly increased in the experimental group. Psychological stress assessed by perceived stress scale also showed a significant drop after the intervention in the test group and the change in perceived stress was again significant between the 2 groups comparison. Conclusion: Along with the standard treatment regimens, diabetic patients can incorporate mind-body relaxation techniques as an effective adjunctive therapy.

Comparison of efficacy of two different doses of tranexamic acid in prevention of post operative blood loss in patients with congenital cyanotic heart disease undergoing cardiac surgery.

Background: The optimal dose of tranexamic acid in minimizing perioperative bleeding is uncertain. We compared efficacy of two different doses of tranexamic acid in reducing post-operative blood loss and its side effects in patients with congenital cyanotic heart disease undergoing cardiac surgery. Settings and Design: Prospective observational study at a pediatric cardiac center in South India. Methods: Consecutive cyanotic patients undergoing cardiac surgery were divided into groups I and II to receive either 10 mg/kg or 25 mg/kg of tranexamic acid administered as triple dose regime after induction, during cardiopulmonary bypass, and after protamine. Post-operative blood loss at 24 hours, blood component utilization, incidence of renal dysfunction and seizures were compared. Results: Totally, 124 patients were recruited, 62 in each group. The pre-operative variables and cardiopulmonary bypass time were comparable. Patients receiving 25 mg/kg had lower post-operative blood loss compared to patients in lower dose group (8.04 ± 8.89 vs 12.41 ± 19.23 ml/kg/24 hours, P = 0.03). There was no difference in the transfused volume of packed red cells (9.21 ± 7.13 ml/kg vs 12.41 ± 9.23 ml/kg, P = 0.712), fresh frozen plasma (13.91 ± 13.38 ml/kg vs 11.02 ± 8.04 ml/kg, P = 0.19), platelets (9.03 ± 6.76 ml/kg vs 10.90 ± 6.9 ml/kg, P = 0.14) or cryoprecipitate (0.66 ± 0.59 ml/kg vs 0.53 ± 0.54 ml/kg, P = 0.5) in group II and I, respectively. Two patients developed renal dysfunction secondary to low cardiac output in lower dose group. There were no seizures. Conclusions: Tranexamic acid administered at a dose of 25 mg/kg as triple dose regime is associated with lower post-operative blood loss compared to a lower dose of 10 mg/kg in cyanotic patients undergoing cardiac surgery without causing major adverse effects.

Changes in Left Ventricular Mass and Cardiovascular Risk Factors after Kidney Transplantation.

Left ventricular hypertrophy (LVH), the most common structural cardiac complication, is the single most important cause for sudden cardiac death. There are no published data from India looking at the changes in left ventricular mass and cardiac dysfunction after kidney transplantation. We aimed to determine the changes in the left ventricular mass and other cardiovascular risk factors in kidney transplant recipients. This was a prospective observational study. All patients who underwent kidney transplantation at Amrita Institute of Medical Sciences and Research Centre, Kochi, Kerala, during the study period were included in the study. Measurement of clinical and biochemical parameters and echocardiography were done before, six months, and one year after transplantation. There was significant reduction in LV mass index (124.8 ± 39 vs. 102.2 ± 24.4 g/m2, P <0.001) and improvement in ejection fraction (57.8 ± 7 vs. 60.1 ± 1.9, P = 0.015) at the end of six months. There were significant differences in the mean hemoglobin, systolic, and diastolic blood pressures (P <0.001) during the study. There was also a significant reduction in the number of antihypertensive drugs required for blood pressure control. There was a significant reduction in LVH in the study group. There was also improvement in systolic and diastolic functions of the heart. There was also a significant improvement in blood pressure control both in terms of mean blood pressure levels as well as in terms of the number of anti-hypertensive drugs needed for blood pressure control. Renal transplantation ameliorates cardiovascular risk in renal transplant recipients.

Exploring the utility of fibreoptic endoscopic evaluation of swallowing in young children- A comparison with videofluoroscopy.

OBJECTIVES/HYPOTHESIS: In adults, fibreoptic endoscopic evaluation of swallowing (FEES) has established its place in the assessment of dysphagia and aspiration vis-à-vis the current gold standard, videofluoroscopic swallow study (VFSS), almost at parity. However, in children with quite a different set of factors in play, its role is not certain. The primary objective was to measure the accuracy of FEES in young children with dysphagia, compared to VFSS. The secondary objective was to correlate other endoscopic findings with aspiration in videofluoroscopy. STUDY DESIGN: Prospective, observational. METHODOLOGY: Sixty-five children, aged 0.4-36 months with suspected oropharyngeal dysphagia and aspiration underwent FEES and VFSS. Sensitivity, specificity, positive predictive value, negative predictive value, accuracy and diagnostic agreement of FEES were calculated using VFSS as the gold standard. To test the statistical significance of the difference in two measurements, Mc Nemar's Chi-square test was used and to test the agreement between FEES and VFSS, Kappa value was calculated. To test the statistical significance of the association of endoscopic findings with VFSS findings, Chi-square test was used. RESULTS: FEES performed in young children was found to be less sensitive (50%) but more specific of aspiration (82%) with an accuracy of 77% in comparison with VFSS. The reverse was true of penetration (81%, 44% and 59% respectively). The agreement between FEES and VFSS in young children, on all parameters were low (k = 0.061-0.302). Endoscopic findings such as glottic secretions (P = 0.02), weak or diminished laryngeal adductor reflex (LAR) (P = 0.001) and penetration (P = 0.01) were significantly associated with aspiration in VFSS. Excessive secretions in the hypopharynx had a stronger correlation with oesophageal dysmotility (P = 0.02) than pharyngeal dysphagia (P = 0.05). CONCLUSION: FEES in young children appears to have a low agreement with VFSS unlike in adults. Aspiration observed in FEES is likely to be significant since specificity is high. FEES negative for aspiration may be interpreted taking into account, the aspiration risk of the subject and/or other endoscopic risk factors (penetration, weak/absent LAR & glottic secretions), if VFSS is not a viable alternative.

Impact of Integrated Amrita Meditation® technique on stress in type 2 diabetic patients.

BACKGROUND & OBJECTIVES: Several studies on mind-body relaxation techniques have demonstrated a reduction in psychological stress levels. Implementation of such cost-effective, persons suffering from chronic disorders would be beneficial for the diabetic population. This study was undertaken to understand the effect of Integrated Amrita Meditation® technique (IAM®) technique on stress and its benefit in attaining a better glycaemic control. METHODS: Thirty type 2 diabetic patients aged between 30 and 65 yr were consecutively recruited for the study. They were randomly allocated to IAM® and control groups. Weight, body mass index (BMI), fasting blood glucose (FBG), glycated haemoglobin (HbA1c) and perceived stress scale (PSS) were the variables assessed pre- and post-intervention during the three-month study period. RESULTS: The mean changes between baseline and three months in the experimental group showed statistically significant decrease in HbA1c (P=0.018) as well as psychological stress (P<0.001), whereas an increase in weight (P=0.046) and FBG (P=0.029) was observed in the control group. When the pre- and post-mean changes of the study variables were assessed between the two groups, the differences obtained were statistically significant for weight (P=0.048), BMI (P=0.055), HbA1c (P=0.034) and PSS (P≤0.001). INTERPRETATION & CONCLUSIONS: The findings suggest that stress is an important risk factor hindering the glycaemic control of diabetic patients. Through reduction of psychological stress by IAM® practice, diabetic patients can attain a better glycaemic control along with the usual treatment regimens.

Prognostic and predictive significance of microsatellite instability in stage II colorectal carcinoma: An 8-year study from a tertiary center in South India.

BACKGROUND: Microsatellite instability (MSI) accounts for 15-20% of colorectal cancer (CRC) and is considered to have favorable stage-adjusted prognosis compared to Microsatellite stable (MSS) CRCs. Determination of MSI in stage II CRC is important for management decisions regarding adjuvant chemotherapy administration. The aim of this study was to determine the prognostic and predictive significance of MSI in stage 2 CRC in the Indian scenario. MATERIALS AND METHODS: A total of 195 patients who underwent curative surgery for stage II CRC from 2010 to 2017 were included. MSI testing by immunohistochemistry (DNA MisMatch Repair proteins) was performed in all. Various clinicopathological factors and disease-free survival and overall survival were assessed between MSI and MSS groups. The effect of treatment in terms of survival benefits with adjuvant therapy in the MSI group was also assessed. RESULTS: 27.1% of the CRCs' showed MSI. Younger age (<50 years), family history of cancer, synchronous/metachronous malignancies, proximal (right sided) location, poor morphological tumour differentiation, mucin production, and presence of peritumoral (Crohn's-like) lymphocytic response showed statistically significant association with MSI. Majority (56%) of our patients showed combined loss of MLH1 and PMS2. Overall, survival among the MSI patients was significantly higher (76.6 ± 4.149 months) than the MSS patients (65.05 ± 3.555)P= 0.04. MSI patients did not show any differences in survival with or without treatment. CONCLUSION: This study highlights the distinct clinicopathological features of MSI-related CRC and the relevance of MSI testing of stage II CRC for management decisions and prognostication.

Hyperbaric oxygen therapy in patients with hypoxic ischemic encephalopathy.

BACKGROUND AND AIM: To assess the efficacy of hyperbaric oxygen therapy (HBOT) in patients with hypoxic ischemic encephalopathy (HIE). DESIGN: Non-randomized case-control observational study. SETTING: Tertiary level neurorehabilitation unit. POPULATION: Twenty-five patients with HIE seen between 1 to 12 months after the injury and having a coma recovery scale-revised (CRS-R) score less than 7 at entry were recruited. METHODS: Out of the patients who received HBOT, 20 received 20 sessions of HBOT at two absolute atmosphere pressure (ATA), and two received 60 sessions at 2 ATA over three different treatment intervals. We compared the outcomes between cases (who received HBOT) and controls (who did not receive HBOT).Cases and controls were allocated to three groups based on the time interval after injury following which they were recruited to the study: 1-3 months (9 cases and 16 controls), 4-8 months (9 cases and 9 controls) and 9-12 months (8 cases and 3 controls). OUTCOME MEASURES: CRS-R, Karnofsky performance scale, and change in disorder of consciousness (DOC) at admission and discharge were assessed. RESULTS: We observed a significant difference in CRS-R favoring the HBOT group at time intervals of 1-3 and 4-8 months. More patients in the HBOT group improved in DOC than the control group. CONCLUSIONS: HBOT given in the first nine months post-HIE can result in a better recovery and functional outcome.

Usefulness of a modified questionnaire as a screening tool for swallowing disorders in Parkinson disease: A pilot study.

AIMS: To determine the correlation between our questionnaire scores and two standard Parkinson's disease (PD) disability scores [Unified Parkinsons' Disease Rating Scale (UPDRS) and Hoehn and Yahr (H and Y)], and to study the correlation between the various subgroups of our dysphagia screening questionnaire. SETTINGS AND DESIGN: This study was conducted at a movement disorder clinic in a tertiary care hospital in Kochi, Kerala. This was a cross-sectional observational study. MATERIALS AND METHODS: A questionnaire was developed comprising 11 items, keeping in mind the most relevant swallowing issues in PD patients. The questions were subdivided into four groups representing the different stages of swallowing. Reliability and validity studies were conducted for the questionnaire. Corresponding UPDRS and H and Y scores were documented on the same day. STATISTICAL ANALYSIS USED: Mean and standard deviation (SD) values of the scores in each group and the correlation between scores (Pearson correlation coefficient) were done. RESULTS: Responses were obtained from 106 PD patients (67 males, 39 females), with a mean age of 66.9 years (SD, 8.62). Our questionnaire score showed a high coefficient of variation (145%) compared to the UPDRS and H and Y scores. There was also moderate correlation between our questionnaire score and the two standard scores with a significant P value. Finally, the highest mean scores were for questions from group A and the least for questions from group D. CONCLUSIONS: The association between worsening motor symptoms and swallowing difficulties has been documented in this study. The oral stage of swallowing remains the most affected in PD, which can be recognized early using our questionnaire.

Predictors of acute kidney injury in patients undergoing adult cardiac surgery.

BACKGROUND: Acute kidney injury (AKI) after cardiac surgery (CS) is not uncommon and has serious effects on mortality and morbidity. A majority of patients suffer mild forms of AKI. There is a paucity of Indian data regarding this important complication after CS. AIMS AND OBJECTIVES: The primary objective was to study the incidence of AKI associated with CS in an Indian study population. Secondary objectives were to describe the risk factors associated with AKI-CS in our population and to generate outcome data in patients who suffer this complication. METHODS: Serial patients (n = 400) presenting for adult CS (emergency/elective) at a tertiary referral care hospital in South India from August 2016 to November 2017 were included as the study individuals. The incidence of AKI-CS AKI network (AKIN criteria), risk factors associated with this condition and the outcomes following AKI-CS are described. RESULTS: Out of 400, 37 (9.25%) patients developed AKI after CS. AKI associated with CS was associated with a mortality of 13.5% (no AKI group mortality 2.8%, P = 0.001 [P < 0.05]). When AKI was severe enough to need renal replacement therapy, the mortality increased to 75%. Patients with AKI had a mean hospital stay 16.92 ± 12.75 days which was comparatively longer than patients without AKI (14 ± 7.98 days). Recent acute coronary syndrome, postoperative atrial fibrillation, and systemic hypertension significantly predicted the onset of AKI-CS in our population. CONCLUSIONS: The overall incidence of AKI-CS was 9.25%. The incidence of AKI-CS requiring dialysis (Stage 3 AKIN) AKI-CS was lower (2%). However, mortality risks were disproportionately high in patients with AKIN Stage 3 AKI-CS (75%). There is a need for quality improvement in the care of patients with AKI-CS in its most severe forms since mortality risks posed by the development of Stage 3 AKIN AKI is higher than reported in other index populations from high resource settings.

Platelet parameters in children with chromosome 22q11 deletion and conotruncal heart defects.

BACKGROUND AND OBJECTIVES: The 22q11 deletion syndrome is associated with a wide spectrum of phenotypic features, hence clinical diagnosis is difficult. Individuals with this syndrome are found to have a risk of developing transfusion associated graft-versus-host reaction, if they are given nonirradiated blood. Our aim was to elucidate whether chromosome 22q11 deletion in children with syndromic conotruncal heart defects is associated with platelet abnormality. MATERIALS AND METHODS: The genetic analysis was performed by standard cytogenetic and Fluorescence in situ hybridization technique. The platelet parameters in 39 patients with chromosome 22q11 deletion were compared with 154 cases without deletion. RESULTS: In deletion versus no deletion group, the mean of mean platelet volume (MPV) was 10.5 ± 2.5 vs 7.6 ± 1.5 fL, platelet count was 225 ± 80.7 and 339 ± 127.3 × 10 9 /L and frequency of high MPV was 49% vs 7% (P < .0001). The MPV was associated with a sensitivity of 90.9% and a specificity of 79.6% at a cutoff value of 8.32 fL, (area under the ROC curve 91%). A nonsignificant negative correlation was found between MPV and platelet count (r = -0.152; P = .361) in children with deletion. CONCLUSION: A cutoff value of 8.32 fL for MPV can be an indicator of high risk of chromosome 22q11 deletion in individuals with syndromic conotruncal defects. Individuals with chromosome 22q11 deletion should be given irradiated blood especially during cardiac surgery. Further investigation should clarify the etiology behind variation in frequency of high MPV in different conotruncal lesions.

A randomized study of coconut oil versus sunflower oil on cardiovascular risk factors in patients with stable coronary heart disease.

BACKGROUND AND RATIONALE: Coronary artery disease (CAD) and its pathological atherosclerotic process are closely related to lipids. Lipids levels are in turn influenced by dietary oils and fats. Saturated fatty acids increase the risk for atherosclerosis by increasing the cholesterol level. This study was conducted to investigate the impact of cooking oil media (coconut oil and sunflower oil) on lipid profile, antioxidant mechanism, and endothelial function in patients with established CAD. DESIGN AND METHODS: In a single center randomized study in India, patients with stable CAD on standard medical care were assigned to receive coconut oil (Group I) or sunflower oil (Group II) as cooking media for 2 years. Anthropometric measurements, serum, lipids, Lipoprotein a, apo B/A-1 ratio, antioxidants, flow-mediated vasodilation, and cardiovascular events were assessed at 3 months, 6 months, 1 year, and 2 years. RESULTS: Hundred patients in each arm completed 2 years with 98% follow-up. There was no statistically significant difference in the anthropometric, biochemical, vascular function, and in cardiovascular events after 2 years. CONCLUSION: Coconut oil even though rich in saturated fatty acids in comparison to sunflower oil when used as cooking oil media over a period of 2 years did not change the lipid-related cardiovascular risk factors and events in those receiving standard medical care.

Surgical treatment pattern and outcomes in epithelial ovarian cancer patients from a cancer institute in Kerala, India.

OBJECTIVE: To evaluate the treatment and survival pattern of patients with advanced epithelial ovarian cancer. METHODS AND RESULTS: Retrospective study of all advanced epithelial ovarian cancer patients treated in the department of gynaecologic oncology from an academic centre, in a four year period from 1 January 2008-31 December 2011. SELECTION CRITERIA: All patients with advanced epithelial ovarian cancer (stage III and IV) who underwent surgery from 2008-2011and had a follow-up of at least three months after completion of treatment were included. The decision on whether primary surgery or neoadjuvant chemotherapy (NACT) in advanced ovarian cancer was based on age, performance status, clinical and imaging findings. RESULTS: A total of 178 cases of epithelial ovarian cancer were operated on during this four year period. Among them 28 patients were recurrent cases, 22 had early stages of ovarian cancer, and the rest 128 had stage III and IV ovarian cancer. In these 128 patients, 50(39.1%) underwent primary surgery and 78(60.9%) had NACT followed by surgery. In the primary surgery group 36(72.0%) patients had optimal debulking while in the NACT group 59(75.6%) patient had optimal debulking. With a median follow-up of 34 months, the median overall survival (OS) and progression free survival (PFS) was 53 and 49 months respectively. Patients who underwent primary surgery had better median PFS than patients who had NACT (56 months versus 39 months, p = 0.002). In stage III C the difference median PFS was significant for those treated with primary surgery when compared with NACT (55 months versus 39 months, p = 0.012). In patients who had optimal debulking to no residual disease (n = 90), primary surgery gave a significant improved PFS (59 months versus 38 months, p = 0.001) when compared with NACT. In univariate analysis, NACT was associated with increased risk of death (HR: 0.350; CI: 0.177-0.693). CONCLUSION: In advanced epithelial ovarian cancer, primary surgery seems to have a definite survival advantage over NACT in patients who can be optimally debulked to no residual disease.

Cardiac spectrum, cytogenetic analysis and thyroid profile of 418 children with Down syndrome from South India: a cross-sectional study.

OBJECTIVE: To describe the spectrum of congenital heart disease in children with Down syndrome and their cytogenetic profile (and that of parents of those with translocation), and thyroid profile. METHODS: A cross sectional study was conducted in 418 consecutive patients with Down syndrome attending the Department of Pediatric Genetics from a tertiary care centre in Kerala with a comprehensive Pediatric Cardiac Program, from November 2005 through April 2012. All children were offered cytogenetic analysis and were subjected to echocardiography. Parental karyotyping was offered for children with translocation type of Down syndrome. The thyroid profiles of all children were checked at the first visit and once every 6 mo during follow up. RESULTS: Congenital heart disease was present in 256 (63.4 %) of 404 children with Down syndrome. Ventricular septal defect (72; 28.1 %) was the commonest, followed by atrio-ventricular septal defect (70; 27.3 %) and patent ductus arteriosus (43; 16.8 %). Surgical correction was accomplished in 104 (40.6 %) with excellent intermediate-term outcomes. Three hundred eighty seven of 418 children (92.6 %) underwent cytogenetic tests. The abnormalities included non-disjunction (340, 87.8 %), translocation (33, 8.5 %) and mosaicism (12, 3.1 %). Hypothyroidism was detected in 57 children (13.6 %). CONCLUSIONS: The prevalence of congenital heart disease in children with Down syndrome in Kerala is the highest reported (63.4 %). Ventricular septal defect is the most common heart disease in the present study. The results highlight the changing attitudes of families towards the surgical correction of congenital heart disease in children with Down syndrome. Prevalence of hypothyroidism in Down syndrome in Kerala is 13.6 %.

Foot care practice - the key to prevent diabetic foot ulcers in India.

BACKGROUND: The magnitude of diabetic foot ulcers (DFUs) and the amputation rates due to DFUs remain high even in developing and developed countries. Yet, the influence of knowledge, attitude, and practice (KAP) of diabetic foot care (DFC) on DFU incidence is not studied much. OBJECTIVE: To study causal relationship between knowledge, attitude and practice (KAP) on DFC between diabetic patients with and without DFUs; and the risk factors associated with DFUs. METHODS: A consecutive of 203 diabetic patients (103 with DFU and 100 without DFU) were included in the study. Their demographic details, medical history, and personal habits were recorded. KAP on DFC was assessed using a questionnaire. Responses were recorded, scored, and analyzed. RESULTS: Of the cohort, 67.5% were males, mean age: 59.9 ± 11.4 years. Patients without DFU had good knowledge on DFC compared to those with DFU (86% versus 69.9%) (p<0.001). Incidence of DFU was 9% and 39.8% (p<0.001) among patients who practiced and not practiced DFC respectively. 88% patients with and without DFUs; showed favorable attitude toward adopting DFC. Risk factors - diabetic peripheral neuropathy, peripheral vascular disease, retinopathy, nephropathy, smoking, tobacco chewing and alcohol consumption were significantly (p<0.001) associated with DFUs. CONCLUSIONS: An inverse relationship between DFU and foot care knowledge as well as practice was observed. Apart from tight glycemic control, diabetic patients must be educated and motivated on proper foot care practice and life style modifications for preventing DFUs.

Targeted treatment of invasive fungal infections accelerates healing of foot wounds in patients with Type 2 diabetes.

AIM: To test the hypothesis that fluconazole plus standard care is superior to the standard care for diabetic foot wounds infected with deep-seated fungal infections. METHODS: We carried out a randomized, controlled, open-label, parallel-arm study in 75 patients with both fungal and bacterial infections in deep tissues of diabetic foot wounds. Thirty-seven patients (control group) were given standard care (surgical debridement + culture-specific antibiotics + offloading + glycaemic control) and 38 patients (treatment group) were given fluconazole 150 mg daily plus standard care. Wound surface area was measured every 2 weeks until the endpoints (complete epithelialization or skin grafting) were met. RESULTS: By week 4, the mean wound surface area reduced to 27.3 from 111.5 cm(2) in the treatment group, as opposed to 67.1 from 87.3 cm(2) in the control group. Subsequently, the mean wound surface areas were remarkably smaller in the treatment group compared with the control group, and statistically significant differences (P ≤ 0.05) in mean wound surface area were observed between the treatment group and the control group at week 6. However, no statistically significant (P ≤ 0.47) difference in complete healing was observed between the treatment group and the control group, 20 vs. 24. The mean wound healing time for the treatment group was 7.3 weeks, whereas for the control group it was 11.3 weeks (P ≤ 0.022). Similarly, the probability of wound healing in the treatment group was 50 vs. 20% in the control group at week 10. CONCLUSIONS: Fluconazole plus standard care was superior to standard care alone in accelerating wound reduction among patients with diabetes with deep-seated fungal infections in diabetic foot wounds. Those in the treatment group who did heal, healed more quickly (P ≤ 0.022), but overall healing was not different.

Diabetes self-efficacy strongly influences actual control of diabetes in patients attending a tertiary hospital in India.

A cross-sectional survey of 507 in- and out-patients, with diagnosed Type 2 diabetes mellitus (T2DM) was undertaken to study the relationships between personal, disease and treatment-related factors and diabetes control in a tertiary care hospital. On multivariate logistic regression analysis, self-efficacy (odds ratio (OR) =2.94; 95% confidence interval (CI) =1.92-4.54); P<0.001) was the single most important determinant of current diabetes control (HbA1c ≤7%), along with absence of hyperglycemic symptoms in the past year (OR=1.83; 95% CI=1.15-2.93, P<0.01), current treatment with oral medication (OR=1.77; 95% CI=1.17-2.66; P<0.007), and adherence to dietary restrictions (OR=2.7; 95% CI=1.28-5.88; P<0.009). Self-efficacy was itself influenced by educational status, employment, availability of family support, and positive mental attitudes. Our findings suggest that health care delivery inputs, patients' personal characteristics including education and attitude, and family support for care are complexly processed to determine patients' ability to manage their disease, which ultimately influences disease outcomes.

Changes in intellectual and academic performance of children following computer-based training: Preliminary results.

BACKGROUND: The aim of this pilot study was to assess the effectiveness of a computer-based intervention on children who were average in academic performance. MATERIALS AND METHODS: Twenty-one children aged between 8 and 11 years, in classes 3(rd), 4(th) or 5(th) formed the sample with 12 in the experimental (who underwent the computer-based training) and 9 in the control group (who did not undergo the training). Pre- and post-assessment was done for all children using a battery of intelligence tests, and the marks obtained by the child at school. The difference in performance of the two groups was compared using the t test. RESULT: There was significant improvement within the performance of the experimental group in cognitive functioning (P<0.05) and school marks (P<0.05), as compared with the children in the control group. The limitations of the study include the small sample size, non-random allocation to groups and the (pre and post) assessments being carried out by the researcher. However, the trend of results is promising. CONCLUSION: Thus, a brief computer-aided intervention for improving neuropsychological functions such as attention and working memory has had a positive impact on the cognitive and academic skills of children who were average in scholastic performance.

Variation in prevalence of chromosome 22q11 deletion in subtypes of conotruncal defect in 254 children.

AIM: To determine the frequency of chromosomal aberrations particularly 22q11 deletion in Indian children ≤2 years with different types of conotruncal malformations and their association with abnormal aortic arch. Additionally, extracardiac features were also studied. METHODS: Conventional cytogenetic and fluorescence in situ hybridization analyses were performed in 254 patients with conotruncal defects. Multivariable logistic regression analysis was performed to ascertain extracardiac features helpful in identifying high-risk patients with deletion. RESULTS: Chromosomal abnormalities were identified in 52 (21%) children, of whom 49 (94%) showed 22q11 deletion and 3 (6%) had abnormalities of chromosome 6, 2 and X. None of the 11/254 children with tetralogy of Fallot with absent pulmonary valve showed deletion. The association of 22q11 deletion with right sidedness of the aortic arch varied with the type of conotruncal defect. The eight extracardiac features in combination showed 93.5% agreement with the presence of deletion. CONCLUSION: The extracardiac features along with specific type of conotruncal defect and associated cardiovascular anomaly should alert the clinician for 22q11 deletion testing. However, if deletion analysis is not possible, specific extracardiac features (six dysmorphic facial features, thin long fingers and hypocalcemia) can help to identify an increased risk of 22q11 deletion in patients with conotruncal defect.

Severe dental fluorosis and jowar consumption in Karnataka, India.

INTRODUCTION: Dental fluorosis is a major public health problem in 17 states of India. Earlier studies have reported that Jowar (a type of millet) consumption interacts with fluoride (F) in the body and enhances fluorosis. We conducted this study to determine the association between jowar consumption and severity of dental fluorosis. METHODS: A community based case control study was carried out in villages having different F levels (low, medium, and high) in drinking water in North Karnataka, India. 352 school Children (12-15 years, male 58%) with severe dental fluorosis classified by Thylstrup & Fejerskov Index (1988) were selected as cases. 428 school children (12-15 years, male 48.8%) with no dental fluorosis were selected randomly from the same area as controls. Exposure ascertainment of jowar consumption was done by 24-h diet recall and food frequency questionnaire. Ion selective electrode method was used to estimate the F level in spot urine samples of subjects and in drinking water. Multiple logistic regression analysis was done using SPSS V. 11.01 RESULTS: Children who consumed jowar had 2.67 times more chance of getting severe dental fluorosis compared to those who did not [Odds Ratio (OR) 2.67, CI 1.98-3.62]. Children from high F level villages (OR 1.91, CI 1.27-2.85) had higher odds of severe dental fluorosis compared to children from medium and low F level villages. Daily jowar consumers (OR 2.14, CI 1.64-3.09) and weekly consumers (OR 1.68, CI 1.31-3.45) had higher risk for dental fluorosis compared to non jowar consumers. Children who started consuming jowar before 8 years of age had significantly higher proportion of severe dental fluorosis compared to their counterparts. Urinary F excretion among jowar consumers was significantly lower than non-jowar consumers. CONCLUSIONS: Jowar consumption was positively associated with severity of dental fluorosis in this population.
