Estimating the Prevalence of Dementia in India Using a Semi-Supervised Machine Learning Approach.

INTRODUCTION: Accurate estimation of dementia prevalence is essential for making effective public and social care policy to support individuals and families suffering from the disease. The purpose of this paper is to estimate the prevalence of dementia in India using a semi-supervised machine learning approach based on a large nationally representative sample. METHODS: The sample of this study is adults 60 years or older in the wave 1 (2017-2019) of the Longitudinal Aging Study in India (LASI). A subsample in LASI received extensive cognitive assessment and clinical consensus ratings and therefore has diagnoses of dementia. A semi-supervised machine learning model was developed to predict the status of dementia for LASI participants without diagnoses. After obtaining the predictions, sampling weights and age standardization to the World Health Organization (WHO) standard population were applied to generate the estimate for prevalence of dementia in India. RESULTS: The prevalence of dementia for those aged 60 years and older in India was 8.44% (95% CI: 7.89%-9.01%). The age-standardized prevalence was estimated to be 8.94% (95% CI: 8.36%-9.55%). The prevalence of dementia was greater for those who were older, were females, received no education, and lived in rural areas. DISCUSSION: The prevalence of dementia in India may be higher than prior estimates derived from local studies. These prevalence estimates provide the information necessary for making long-term planning of public and social care policy. The semi-supervised machine learning approach adopted in this paper may also be useful for other large population aging studies that have a similar data structure.

Cohort Profile: Real-Time Insights of COVID-19 in India (RTI COVID-India).

BACKGROUND: The coronavirus disease (COVID) pandemic caused disruption globally and was particularly distressing in low- and middle-income countries such as India. This study aimed to provide population representative estimates of COVID-related outcomes in India over time and characterize how COVID-related changes and impacts differ by key socioeconomic groups across the life course. METHODS: The sample was leveraged from an existing nationally representative study on cognition and dementia in India: Harmonized Diagnostic Assessment of Dementia for the Longitudinal Aging Study in India (LASI-DAD). The wave-1 of LASI-DAD enrolled 4096 older adults aged 60 years and older in 3316 households from 18 states and union territories of India. Out of the 3316 LASI-DAD households, 2704 with valid phone numbers were contacted and invited to participate in the Real-Time Insights COVID-19 in India (RTI COVID-India) study. RTI COVID-India was a bi-monthly phone survey that provided insight into the individual's knowledge, attitudes, and behaviour towards COVID-19 and changes in the household's economic and health conditions throughout the pandemic. The survey was started in May 2020 and 9 rounds of data have been collected. FINDINGS TILL DATE: Out of the 2704 LASI-DAD households with valid phone numbers, 1766 households participated in the RTI COVID-India survey at least once. Participants were in the age range of 18-102 years, 49% were female, 66% resided in rural area. Across all rounds, there was a higher report of infection among respondents aged 60-69 years. There was a greater prevalence of COVID-19 diagnosis reported in urban (23.0%) compared to rural areas (9.8%). Respondents with higher education had a greater prevalence of COVID-19 diagnosis compared to those with lower or no formal education. Highest prevalence of COVID-19 diagnosis was reported from high economic status compared to middle and low economic status households. Comparing education gradients in experiencing COVID-19 symptoms and being diagnosed, we observe an opposite pattern: respondents with no formal schooling reported the highest level of experiencing COVID-19 symptoms, whereas the greatest proportion of the respondents with secondary school or higher education reported being diagnosed with COVID-19. FUTURE PLANS: The study group will analyse the data collected showing the real-time changes throughout the pandemic and will make the data widely available for researchers to conduct further studies.

Morphometric characteristics and microsatellite markers based diversity and differentiation recognizes the first prospective cattle breed from the Jharkhand state of India.

India is bestowed with immense cattle biodiversity with 50 registered breeds. However, the majority (59.3%) is yet not characterized. Identification and characterization are the gateways to the management of prized indigenous resources. Present research described a unique cattle population of Jharkhand state, managed under a traditional low-input, low-output system. It was characterized by morphological traits, performance parameters, and management practices. Animals have the characteristic pre-scapular location of the hump. Genetic variation within this population and its differentiation with the six closely distributed cattle breeds were evaluated using FAO recommended microsatellite markers. Jharkhandi cattle have substantial genetic variation based on gene diversity (>0.6) and the average number of alleles per locus (>8). The population did not suffer from a genetic bottleneck in the recent past. Pairwise Nei's genetic distance, phylogenetic relationship, population differentiation, and the correct assignment of all the animals to self group substantiated its separate genetic identity. Since gene flow (Nm = 2.8-7.32) was identified and admixture was indicated by the Bayesian analysis there is a pressing need for scientific management of this population. Results endow authorities with critical information for registering a new Indian cattle breed (Medini) that contributes to the food security, livelihood, and economic sustainability of rural tribal households.

Performance of the Informant Questionnaire on Cognitive Decline for the Elderly (IQCODE) in a nationally representative study in India: the LASI-DAD study.

BACKGROUND: Low and middle-income countries like India anticipate rapid population aging and increases in dementia burden. In India, dementia screening scales originally developed in other contexts need to be assessed for feasibility and validity, given the number of different languages and varying levels of literacy and education. METHOD: Using data from the Longitudinal Aging Study in India-Diagnostic Assessment of Dementia (N = 4,028), we characterize the performance of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). We described patterns and correlates of missingness, evaluated the psychometric properties of the scale, and assessed criterion validity against the Hindi Mental State Examination (HMSE) using linear regression. RESULTS: Several IQCODE items had high levels of missingness, which was associated with urbanicity, respondent's gender, and informant's generation (same vs. younger generation). Full IQCODE scores showed strong criterion validity against the HMSE; each 1-point increase in IQCODE score was associated with a 3.03-point lower score on the HMSE, controlling for age, gender, and urbanicity. The statistically significant association between IQCODE and HMSE was stronger in urban than rural settings (p-value for interaction = 0.04). Associations between IQCODE and HMSE remained unchanged after removing the three items with the highest levels of differential missingness (remembering addresses and telephone numbers, ability to work with familiar machines, ability to learn to use new gadget or machine). CONCLUSION: Findings raise questions about the value of including items with high proportions of missingness, which may signal cultural irrelevance, while removing them did not affect criterion validity.

Serum sestrins: potential predictive molecule in human sarcopenia.

BACKGROUND: The aging trajectory from a state of robustness and good health proceeds from sarcopenia to frailty followed by disability and death due to decline in skeletal muscle mass and function. Sarcopenia is now formally recognized as a muscle disease with an ICD-10-MC diagnosis code. The autophagic response seems to be affected in the skeletal muscle during aging contributing to sarcopenia. Sestrins (Sesns) proteins play a critical role in autophagy induction under cellular stress conditions. AIMS: The study aims to identify sarcopenia in older adults using Asian Working group guidelines (AWGS) to determine clinically relevant cut-off levels for diagnosis and their association with antioxidant protein Sesns. METHODS: The study recruited 102 older adults attending Geriatric medicine OPD AIIMS, New Delhi, India. The level of serum Sesns were evaluated by Surface Plasmon Resonance (SPR) and validated by immunoblotting. Fifty older adults were diagnosed as sarcopenics according to AWGS. RESULTS: Sesn 1 (p = 0.0448) and Sesn 2 (p < 0.0001) levels were significantly reduced in sarcopenic compared to non-sarcopenic. ROC analysis showed a better cut-off of Sesn 2; 10.104 ng/µL with 92% sensitivity and 84% specificity. Even after adjusting the values with respect to confounding factors, Sesn levels remained significantly reduced in sarcopenics (p < 0.030). DISCUSSION: The level of Sesn 2 showed positive co-relation with the characteristics of sarcopenia. This study first time reported the concentration of serum sestrin in sarcopenic older adults. CONCLUSION: It can be concluded that sarcopenia can be diagnosed at the early stage by using the serum sestrin scale as one of the potential biomarker.

Programmed death-1+ T cells inhibit effector T cells at the pathological site of miliary tuberculosis.

Optimal T cell activation is vital for the successful resolution of microbial infections. Programmed death-1 (PD-1) is a key immune check-point receptor expressed by activated T cells. Aberrant/excessive inhibition mediated by PD-1 may impair host immunity to Mycobacterium tuberculosis infection, leading to disseminated disease such as miliary tuberculosis (MTB). PD-1 mediated inhibition of T cells in pulmonary tuberculosis and TB pleurisy is reported. However, their role in MTB, particularly at the pathological site, remains to be addressed. The objective of this study was to investigate the role of PD-1-PD-ligand 1 (PD-L1) in T cell responses at the pathological site from patients of TB pleurisy and MTB as clinical models of contained and disseminated forms of tuberculosis, respectively. We examined the expression and function of PD-1 and its ligands (PD-L1-PD-L2) on host immune cells among tuberculosis patients. Bronchoalveolar lavage-derived CD3 T cells in MTB expressed PD-1 (54·2 ± 27·4%, P ≥ 0·0009) with significantly higher PD-1 ligand-positive T cells (PD-L1: 19·8 ± 11·8%; P ≥ 0·019, PD-L2: 12·6 ± 6·2%; P ≥ 0·023), CD19+ B cells (PD-L1: 14·4 ± 10·4%; P ≥ 0·042, PD-L2: 2·6 ± 1·43%; not significant) and CD14+ monocytes (PD-L1: 40·2 ± 20·1%; P ≥ 0·047, PD-L2: 22·4 ± 15·6%; P ≥ 0·032) compared with peripheral blood (PB) of MTB and healthy controls. The expression of PD-1 was associated with a diminished number of cells producing effector cytokines interferon (IFN)-γ, tumour necrosis factor (TNF)-α, interleukin (IL)-2 and elevated apoptosis. Locally accumulated T cells were predominantly PD-1+ -PD-L1+ , and blocking this pathway restores the protective T cell response. We conclude that M. tuberculosis exploits the PD-1 pathway to evade the host immune response by altering the T helper type 1 (Th1) and Th2 balance at the pathological site of MTB, thereby favouring disease dissemination.

Products of the Propargyl Self-Reaction at High Temperatures Investigated by IR/UV Ion Dip Spectroscopy.

The propargyl radical is considered to be of key importance in the formation of the first aromatic ring in combustion processes. Here we study the bimolecular (self-) reactions of propargyl in a high-temperature pyrolysis flow reactor. The aromatic reaction products are identified by IR/UV ion dip spectroscopy, using the free electron laser FELIX as mid-infrared source. This technique combines mass selectivity with structural sensitivity. We identified several aromatic reaction products based on their infrared spectra, among them benzene, naphthalene, phenanthrene, indene, biphenyl, and surprisingly a number of aromatic compounds with acetylenic (ethynyl) side chains. The observation of benzene confirms that propargyl is involved in the formation of the first aromatic ring. The observation of compounds with acetylenic side chains shows that, in addition to a propargyl- and phenyl-based mechanism, the HACA (hydrogen abstraction C2H2 addition) mechanism of polycyclic aromatic hydrocarbons formation is present, although no acetylene was used as a reactant. On the basis of the experimental results we suggest a mechanism that connects the two pathways.

Attenuation of the cyproterone acetate-induced testicular hypofunction by a novel nutraceutical lycopene: a genomic approach.

This study was designed to explore the cyproterone acetate (CPA)-induced andrological hypofunction and its correction by oral administration of lycopene. In this concern, spermatogenic, biochemical, histological and genomic profiles were studied. Cyproterone acetate administration for 1 month helped to develop infertile model rats. A significant recovery was noted in sperm motility, sperm count, sperm viability, hypo-osmotic swelling tail-coiled spermatozoa; activities of testicular ∆5 , 3ß-hydroxysteroid dehydrogenase (HSD), 17ß-HSD, catalase (CAT) and superoxide dismutase (SOD); and levels of conjugated diene (CD), malondialdehyde (MDA), testicular cholesterol and serum testosterone after the administration of lycopene at 1.5 mg/0.5 ml Tween-80/100 g body weight/day for last 1 month to infertile model rats. Simultaneously, qRT-PCR study of Bax, Bcl-2, caspase-3, ∆5 , 3ß-HSD and 17ß-HSD genes in testicular tissue showed a significant rectification towards the control in CPA-pre-treated cum CPA-lycopene-cotreated rats. Side-by-side histological and histometric studies showed a significant correction in qualitative analysis of spermatogenesis and seminiferous tubular diameter (STD) in CPA-pre-treated cum CPA-lycopene-cotreated rats. Lycopene showed outstanding efficacy in the management of CPA-induced testicular hypofunction with special reference to correction in oxidative stress-induced testicular apoptosis at genomic level.

Randomized Controlled Trial of Slow Versus Rapid Enteral Feeding Advancements on the Clinical Outcomes in Very Low Birth Weight Neonates.

Starting and advancement of feeding in very low birth weight (VLBW) infants are big challenges for the neonatal practitioners. Wide variations in volume of feed advancement have observed in earlier trials both in slow and rapid advancement groups. Volume advancement in slow advancement groups have ranged from 10ml/kg/day to 23ml/kg/day and in rapid advancement groups have ranged from 15ml/kg/day to 45ml/kg/day in earlier different studies. This randomized controlled trial was conducted in neonatal intensive care unit (NICU) of Bangabandhu Sheikh Mujib Medical University (BSMMU) from April 2013 to July 2014 to evaluate the effects of slow versus rapid rates of feeding advancements on the clinical outcomes in very low birth weight infants. A total 95 infants were enrolled into two strata according to their birth weight. Infants of each stratum were randomly allocated to either slow or rapid advancement group during initiation of feeding. After gut priming over five days, feeding was advanced daily 10ml/kg in slow and 15ml/kg in rapid advancement group for 1000 - <1250gm weighing infants. For 1250 - <1500gm weighing infants, feeding was advanced daily 15ml/kg in slow and 20ml/kg in rapid advancement group. The primary outcome variable was time taken to achieve full enteral feed. Total 82 infants completed the trial. Demographically both groups were same. Infants in the rapid feeding advancement group achieved full enteral feedings before the slow advancement group, had significantly fewer days of parenteral nutrition and regained birth weight earlier. There were no statistical differences in episodes of feed interruption, number of infants with apnea, feed intolerance or diagnosis of sepsis. Rapid enteral feeding advancements were well tolerated by very low birth weight infants.

Comparison of Serum Bilirubin with Transcutaneous Bilirubinometry in Late Preterm and Term Newborn.

Neonatal jaundice or hyperbilirubinemia is a common occurrence in newborns. It can progress to develop kernicterus unless intervention is initiated. Severity and decision for management are usually based on serum bilirubin which needs blood sampling. Transcutaneous bilirubin measurement is a noninvasive technique and correlates closely with serum bilirubin. This Cross sectional study was done in the Department of Neonatology, Bangabandhu Sheikh Mujib Medical University from March 2013 to August 2014 to evaluate the transcutaneous bilirubin in comparison to serum bilirubin. Total 160 infants with ≥35 weeks were purposively included over a period of 16 months. Neonates with less than 35 weeks, previously exposed to phototherapy, serious illness which leads to impaired circulation, who have had exchange transfusion, having major congenital malformation were excluded. Transcutaneous bilirubin measurement was performed within 30 minutes of obtaining sample for total serum bilirubin measurements. Of the enrolled infants, mean birth weight was 2631±520 grams, postnatal age was 4.99±3.02 days ranging from 2 to 25 days and mean transcutaneous bilirubin and serum bilirubin value was 14.59±2.55 and 13.62±2.86mg/dl respectively. Mean difference of transcutaneous bilirubin and serum bilirubin was 0.97±1.01mg/dl. In the total enrolled infant, transcutaneous bilirubin and serum bilirubin values showed significant correlation (r = 0.93, r2 = 0.876, p<0.001) and this was not affected by sex, gestational age, postnatal age, and birth weight. The area under ROC curve for transcutaneous bilirubin was 87% (p value <0.001). If the cut off value of transcutaneous bilirubin was set at 15 mg/dl, then a sensitivity of 77%, specificity of 88% and accuracy of 82% were obtained. Use of transcutaneous bilirubin can reduce need for serum bilirubin in assaying neonatal jaundice; as it showed significantly high correlation with serum bilirubin. Predictive accuracy of transcutaneous bilirubin was found to be statistically significant in comparison to serum bilirubin.

Neonatal Conjunctivitis Leading to Neonatal Sepsis--A Case Report.

Neonatal conjunctivitis is the most common occular disease in neonates. Most infections are acquired during vaginal delivery. In spite most of these cases are benign; some of them may progress to systemic complications like loss of vision if left untreated. The authors present a case of a newborn who developed late onset neonatal sepsis from E. coli positive conjunctivitis. The baby was treated with Injection Meropenem and Injection Amikacin for 10 days. The course was uneventful, after that baby responded well and discharged home on 24th day.

Salt Losing Variety of Congenital Adrenal Hyperplasia--A Case Report.

Congenital adrenal hyperplasia is a genetic endocrinologic disorder. The severe classic form occurs in one in 15,000 births worldwide. Twenty-one-hydroxylase deficiency (21-OHD) is the most common cause in this autosomal recessive disease. It can cause virilization, ambiguous genitalia at birth and severe life threatening condition due to salt wasting. In this report we describe the clinical course of a male neonate presenting with lethargy, failure to thrive (FTT), genital pigmentation, electrolytes imbalance and high serum 17-hydroxy-progesterone (17-OHP) level and subsequently diagnosed as Congenital Adrenal Hyperplasia. After the initial crises management, the child was continued on replacement therapy. During the follow up, he was found to grow appropriately and achieving normal milestones for age.

A Survey on Current Practice of Management of Early Onset Neonatal Sepsis.

It was a survey type of cross sectional study where the participants were from different teaching/referral hospital across the country and was done to gather information regarding current practice of management of neonatal sepsis among paediatricians and neonatologists and was conducted on the spot during a national conference of Bangladesh Perinatal Society in December 2013. Specialists in neonatology, paediatrics, and some other disciplines working in different institutes across the country were requested to respond. Out of 150 physicians, 92 (61.33%) were neonatologists. Physicians suspected early onset neonatal sepsis (EONS) when there is history suggestive of prolonged rupture of membrane (74.77%), prolonged labour (9.33%), chorioamnionitis (7.33%) and maternal fever (2%). Clinical sepsis is found commonly (53.33%) which is later proved by laboratory evidences such as Hb%, TC, DC PBF (peripheral blood film), C-reactive protein, chest X-ray etc. Injection Ampicillin and Gentamycin are still the first choice of antibiotics (61.3%). Preferred route was intravenous (95.3%). Antibiotics were given for 7-10 days by most of the physicians (48.77%). However there is lack of uniformity among the participants in regard to taking decision about antibiotics, the choice of first line and the subsequent options of antibiotics. So, neonatal sepsis is the most important cause of neonatal mortality in the community. Therefore a standard protocolized approach for diagnosis and management of Early Onset Neonatal Sepsis may prove critical which is currently not in practice uniformly.

Association between dental prosthesis need, nutritional status and quality of life of elderly subjects.

PURPOSE: To determine the effect of prosthesis need on nutritional status and oral health-related quality of life (OHrQoL) in elderly and to check the disparity between prosthesis need and prosthesis want in the Indian elderly. METHODS: A total of 946 geriatric participants reporting to a geriatric medicine clinic were recruited in the study. Mini-nutritional assessment (MNA), geriatric oral health assessment (GOHAI) indices, prosthesis need according to WHO criteria, and prosthesis want was recorded along with age, gender, socioeconomic status and posterior occluding pair. RESULTS: Significant associations exist between prosthesis need and age (p = 0.005), MNA (p = 0.006) and GOHAI (p = 0.000). Prosthesis demand too was influenced by age (p = 0.004), posterior occluding pairs (p = 0.000), MNA (p = 0.012) and GOHAI (p = 0.000). GOHAI was negatively correlated with upper (r = -0.445) and lower prosthesis need (r = -0.460). Participants with some prosthesis need had significantly lower MNA and GOHAI scores as compared to those with no prosthesis need. Though prosthesis need was high (79.7 %), demand was low (39.3 %). CONCLUSION: Prosthesis need affects nutritional status and OHrQoL in elderly, and a wide gap exists between need and want of prosthesis.

16S rDNA analysis of archaea indicates dominance of Methanobacterium and high abundance of Methanomassiliicoccaceae in rumen of Nili-Ravi buffalo.

The molecular diversity of rumen methanogens was investigated using 16S rDNA gene library prepared from the rumen contents of Nili-Ravi buffaloes. Microbial genomic DNA was isolated from four adult male fistulated buffaloes and PCR conditions were set up using specific primers. Amplified product was cloned into a suitable vector, and the inserts of positive clones were sequenced. A total of 142 clones were examined, and the analysis revealed 46 species level (0.01 distance) operational taxonomic units (OTUs). Twenty six OTUs comprising 89 clones (63% of the total clones) were taxonomically assigned to Methanobacterium genus and the majority of them had highest percent identity with Methanobacterium flexile among cultured methanogens. Five OTUs comprising 27 clones (19% of total clones) were taxonomically assigned to Methanomicrobium genus and these clones showed highest sequence identity with Methanomicrobium mobile. Only two OTUs comprising 6 clones (4% of total clones) were assigned to Methanobrevibacter genus. A total of 17 clones belonging to 10 species level OTUs showed highest percent identity (ranging from 85 to 95%) with Methanomassilicoccus luminyensis and were taxonomically classified as Methanomassiliicocaceae. Out of the 142 rDNA clones, 112 clones, which constitute 79% of the total clones representing 42 OTUs, had less than 98.5% sequence identity with any of the cultured strains of methanogens and represent novel species of methanogens. This study has revealed the largest assortment of hydrogenotrophic methanogen phylotypes ever identified from the rumen of Nili-Ravi buffaloes. The study indicates that Methanobacterium is the most dominant methanogen in the rumen of Nili-Ravi buffalo. This is also the first report on the presence of methanogens phylogenetically close to M. luminyensis, an H2 dependent methylotrophic methanogen, in the rumen of buffaloes at such a high level of abundance.

Osteopenia of Prematurity: Are We at Risk?

The continuous advances in intensive care have led to increased survival of premature infants. As a consequence, the problem of less imminent, slowly progressing disorders such as osteopenia of prematurity has been emerging. Osteopenia of prematurity (OOP) also called metabolic bone disease of prematurity (MBD) or rickets of prematurity is characterized by a reduction in bone mineral content usually manifest between 6th to 12th weeks of corrected gestational age. It occurs in up to 55% of infants born with weight <1000gm and 23% of infants weighing <1500gm. Clinical features of osteopenia of prematurity are mostly non-specific often appears as a late symptoms. Several biochemical markers have frequently been used as screening tools and diagnostic markers, but timing of measurements and the levels at which treatment should be initiated vary widely. Dual energy X-ray absorptiometry (DEXA) and Quantitative ultrasnogram are important diagnostic tool. Standard X-ray, a widely accepted but cannot detect osteopenia unless 20% loss of bone mineralization. The treatment of osteopenia includes provision of adequate mineral supplementation. Monitoring of serum and urinary markers are mandatory. The focus on prevention has largely centered on providing adequate intake of phosphorus and calcium but more research is needed. Till date there are neither enough data regarding clinical risk factors, valid biochemical markers which can detect premature babies at risk of osteopenia nor supplementation as well as appropriate timely management protocol is practicing in Bangladesh.

Physico-chemical characterization and biological response of Labeo rohita-derived hydroxyapatite scaffold.

The chemically treated Labeo rohita scale is used for synthesizing hydroxyapatite (HAp) biomaterials. Thermogravimetric and differential thermal analyses of fish scale materials reveal the different phase changes with temperature and find out the suitable calcination temperatures. The composition and structures of wet ball-milled calcined HAp powders are characterized by Fourier transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray analysis (EDX). The EDX as well as chemical analysis of fish scale-derived apatite materials confirms that the Ca/P ratio is 1.71. The compressive stress, hardness and porosity have been evaluated on sintered HAp biomaterials. The cell attachment on HAp surfaces, cytotoxicity evaluation and MTT assay, which are carried out in RAW macrophage-like cell line media demonstrate good biocompatibility. The histological analysis also supports the bioaffinity of processed HAp biomaterials in Wistar rat model for investigating the contact reaction and stability at the artificial or natural prosthesis interface.

Does elevating the fetal head prior to delivery using a fetal pillow reduce maternal and fetal complications in a full dilatation caesarean section? A prospective study with historical controls.

A caesarean section at full dilatation (CSFD) can be technically demanding and has consistent association with increased intraoperative trauma. There is evidence that the incidence of caesarean sections at full dilation is on the rise. We report on a prospective study of 50 women undergoing CSFD using a fetal pillow (FP) to elevate the fetal head. Data were compared with historical controls of 124 women without FP use on uterine extensions, uterine incision delivery interval, blood loss, need for transfusion, operating time, length of stay, intensive care unit admission. The FP elevated the fetal head in all 50 women (p < 0.001). We found that patients in the FP group had a lower incidence of extensions (p = 0.03), shorter operating time (p < 0.001), uterine incision to delivery interval (p < 0.001) and shorter length of hospital stay (p < 0.001). Blood loss > 1,000 ml and admission to ICU was also lower but were not statistically significant. There were no significant differences in the fetal complications studied, APGAR scores, admission to neonatal intensive care unit, seizures, neonatal injury or death.

Newborn hearing screening: what are we missing?

The objectives of the study were to demonstrate hearing status in newborns at first screening by Transient Evoked Otoacoustic Emissions and to find out the relationship between abnormal hearing screening and known risk factors. This study was conducted in the department of neonatology of Bangabandhu Sheikh Mujib Medical University in collaboration with department of otolaryngology and department of obstetrics and gynaecology. This prospective observational study included a cohort of 168 neonates from Neonatal Intensive Care Unit and neonatal Nursery (Minimal care unit). All were screened for hearing impairment using Transient Evoked Otoacoustic Emissions in out-patient department of otolaryngology by a trained audiologist before discharge from hospital. Risk factors analysed were according to the criteria of American Academy of Pediatrics. Of the total neonates screened, Refer rate was 32.7% irrespective of presence or absence of risk factors. Small for gestational age, in-utero infections, ototoxic medications, birth weight < 1500, sepsis/meningitis, hyperbilirubinemia were found to be significant risk factors (p < 0.0001). It can be recommended that hearing screening should be universally done for all newborns.

Prevalence of DSM-5 mild and major neurocognitive disorder in India: Results from the LASI-DAD.

INTRODUCTION: India, with its rapidly aging population, faces an alarming burden of dementia. We implemented DSM-5 criteria in large-scale, nationally representative survey data in India to characterize the prevalence of mild and major Neurocognitive disorder. METHODS: The Harmonized Diagnostic Assessment of Dementia for the Longitudinal Aging Study in India (LASI-DAD) (N = 4,096) is a nationally representative cohort study in India using multistage area probability sampling methods. Using neuropsychological testing and informant reports, we defined DSM-5 mild and major neurocognitive disorder, reported its prevalence, and evaluated criterion and construct validity of the algorithm using clinician-adjudicated Clinical Dementia Ratings (CDR)®. RESULTS: The prevalence of mild and major neurocognitive disorder, weighted to the population, is 17.6% and 7.2%. Demographic gradients with respect to age and education conform to hypothesized patterns. Among N = 2,390 participants with a clinician-adjudicated CDR, CDR ratings and DSM-5 classification agreed for N = 2,139 (89.5%) participants. DISCUSSION: The prevalence of dementia in India is higher than previously recognized. These findings, coupled with a growing number of older adults in the coming decades in India, have important implications for society, public health, and families. We are aware of no previous Indian population-representative estimates of mild cognitive impairment, a group which will be increasingly important in coming years to identify for potential therapeutic treatment.
