Cognitive impairment and its predictors: A cross-sectional study among the elderly in a rural community of West Bengal

Context:

With the aging of Indian society, maintaining salubrious cognitive health in late life is a public health priority. Early detection and possible prevention of cognitive impairment (CI), thus, will help in increasing the quality of life of elderly people and decreasing the social, psychological, and economic burden of their families and caregivers.

Aims:

The study aimed to assess proportion of CI and its predictors.

Settings and Design:

This community-based cross-sectional study was conducted among 135 elderly people selected from 15 villages out of a total 64 villages in rural field practice area Singur of AIIH&PH, Kolkata.

Methods and Material:

Cluster sampling technique was used and villages were selected according to probability proportional to size method. Data was collected using a predesigned, pretested structured schedule, which included sociodemographic and behavioral variables, Montreal cognitive assessment tool, Geriatric depression scale short form (GDS 15), and mini nutritional assessment tool.

Statistical Analysis Used:

Predictors of CI were assessed by univariate and multivariable logistic regression using MS-Excel 2016 and SPSS version 16 software.

Results:

Mean age of the study participants was 67.03 ± 6.7 years with 51.9% of them being females. Proportion of CI was observed to be 48.1% which was significantly associated with increasing age [AOR = 1.1 (1.02–1.13)], decreasing years of schooling [AOR = 1.1 (1.01–1.2)], depression [AOR = 2.7 (1.3–5.8)], and malnourished group [AOR = 4.5 (1.01–20.3)]

Conclusion:

The burden of CI among the study population was found to be quite high. It is an alarming situation which needs improved screening facility for early detection. Nutritional upliftment and screening for depression should also be done on a regular basis.

Tobacco exposure is a menace among women: – A cross-sectional study in a rural area of West Bengal, India

Context:

In India, despite implementation of the strategies under National Tobacco Control Programme [NTCP], women are easily exposed to tobacco consumption that is smokeless (SLT) and smoking tobacco along with second-hand smoke [SHS], making them highly susceptible to tobacco hazards.

Aims:

This study aimed to assess the exposure of women to tobacco use and SHS at home and to elicit predictors of tobacco exposure in a rural community of West Bengal.

Methodology:

A community based, cross-sectional study was conducted among 176 women aged 18 years and above. Data was collected by cluster sampling technique (16*11) using predesigned pretested structured schedule. Tobacco exposure was measured using a composite score including tobacco consumption and SHS at home.

Results:

Tobacco use (SLT and smoking tobacco) was significantly associated with educational attainment [AOR = 2.12], occupation [AOR = 2.13] and knowledge [AOR = 1.22]. There was significant association between SHS at home with knowledge [AOR = 1.16] and attitude of the study subjects. [AOR = 1.93]. Overall tobacco exposure (SLT, smoking tobacco, and SHS), was found to be 79.5%. Significant association was found between high tobacco exposure with age group [AOR = 3.82], educational attainment [AOR = 1.74] and knowledge regarding hazards of tobacco [AOR = 1.31].

Conclusion:

Prevalence of SLT use as well as exposure of women to SHS at home is unexpectedly high in the study population. Women specific information and education campaigns focusing on tobacco hazards (both tobacco use and SHS) through existing primary health care infrastructure should be strategized under NTCP.

Status of maternal health care services: An assessment study in slums of Kolkata

Background and Aims:

Mothers constitute an important and priority group in any community due to their high pregnancy related morbidities and mortality. The prevention of pregnancy related complications was possible with proper utilisation of maternal health care services. This study was conducted with the aim of assessing the utilisation of maternal health care services among mothers with younger child aged ≤3 years in slums of Kolkata, West Bengal and to find out the factors associated with it.

Methodology:

It was a community-based, observational study with cross-sectional design conducted in slums of Kolkata from June 2017 to May 2018. 30 slums [under Kolkata municipal corporation] were selected by cluster sampling technique using probability proportionate to size method. 10 mothers were selected from each slum and a total of 300 mothers were selected for the study. A pre-designed, pre-tested, structured schedule was used for data collection.

Results:

The mean age of the mothers was 23.83 (±3.64) years with the age ranging from 18 to 35 years. 75.7% mothers were registered in 1^st trimester of pregnancy and 100% mothers received ≥4 antenatal check-ups. But only 78% mothers consumed ≥100 IFA tablets and only 23.3% mothers consumed ≥360 calcium tablets in antenatal period. 80.3% of the mothers had unsatisfactory utilisation of maternal health care services. Unsatisfactory utilisation of maternal care services was significantly associated with the younger age of the mothers, a smaller number of pregnancies and teenage marriage.

Conclusion:

Utilisation maternal health care services was not satisfactory among mothers in slums of Kolkata. Awareness generation and behaviour change communication among mothers is necessary for proper utilisation of the services.

Comparative Analysis of Alzheimer Questionnaire and Montreal Cognitive Assessment Tool for Cognitive Impairment Screening among the Elderly Population

Introduction: Alzheimer Questionnaire (AQ) and Montreal Cognitive Assessment (MoCA) are tools for assessment of cognitive impairment. MoCA is a common tool for screening of cognitive impairment but it requires trained personnel. AQ questionnaire is informant-based, simple and less time consuming with or without the involvement of trained personnel. Aim: To estimate the prevalence of cognitive impairment and to find out the accuracy of AQ compared to MoCA in Cognitive Impairment screening among elderly population in an urban area of West Bengal. Materials and Methods: The Prospective cross-sectional study was conducted in urban field practice area of All India Institute of Hygiene and Public Health, Kolkata among 140 randomly selected elderly population from June to September 2019. Accuracy of AQ with MoCA tool as gold standard in screening cognitive impairment was analysed by Cohen’s Kappa, Receiver Operating Characteristics (ROC) Curve, Spearman rho Coefficient along with sensitivity, specificity, predictive values and likelihood ratio was obtained. Results: Prevalence of cognitive impairment using MoCA and AQ was 40% (95% CI=31.8-48.6) and 36.4% (95% CI=28.5-45.0), respectively. AQ and MoCA showed good agreement (Cohen’s kappa, κ=0.834; 95% CI=0.739-0.928). The AQ and MoCA showed a strong negative correlation (spearman’s Rho=-0.709; 95%CI=0.764-0.884, p-value <0.001). Considering MoCA as gold standard, AQ showed sensitivity of 85.7% (95% CI=74.2-92.6), specificity of 96.4% (95% CI=89.9-98.7) for cognitive impairment screening and the Positive predictive value of this tool was 94.1% (95% CI=84.0-97.9%). The Youden index of 0.821 showed highest sum of sensitivity and specificity of AQ tool at 4.5 score to anticipate cognitive impairment. Conclusion: AQ is equally effective as MoCA to screen cognitive impairment among elderly at the community level. AQ can be used even by grass root level health workers without involvement of trained personnel. So, community level screening of elderly for cognitive dysfunction can be made even in resource poor settings. Early identification and referral of elderly with cognitive dysfunction will help them in better living.

Nutritional status and eating behavior of children: A study among primary school children in a rural area of West Bengal

Background:

Dietary preferences and childhood eating behavior has marked influence on nutritional status of children. The objective of the study was to find out eating behavior of primary school children in a rural area of West Bengal using Child Eating Behavior Questionnaire and to determine association of body mass index (BMI) with eating behavior.

Methodology:

It was an institution-based observational study with cross-sectional design done from May to August, 2018. The study was done among 142 children studying at four primary schools at Singur, in the rural field practice area of our institute. The four schools were selected randomly using list of primary schools in the area. Eating behavior of children was assessed using Child Eating Behavior Questionnaire (CEBQ). BMI of the children was assessed using WHO Z scores tables for children. Data analysis was done using SPSS Version 16 and binary logistic regression was done to find out association of BMI with eating behavior of study participants.

Results:

The proportion of under-nutrition and overnutrition was 22.0% and 16.0%, respectively. Food fussiness was significantly associated with thinness [BMI below (−2SD)]. Enjoyment of food, satiety response was significantly associated with overnutrition [BMI above (+1 SD)]. Food avoidance subscale was significantly associated with thinness [OR: 2.5, CI: 1.11, 5.63] and this subscale was protective for overweight [OR: 0.22, CI: 0.07, 0.69].

Conclusion:

This study showed association of BMI with child eating behavior. Therefore, awareness among parents should be created to change problematic eating of their children which would further help them to achieve normal BMI.

Morbidities of rice mill workers and associated factors in a block of West Bengal: A matter of concern

Context:

Rice mill workers usually belong to unorganized sector and lack in training regarding hazard prevention. Unprotected exposure to suspended particles and fumes can lead to respiratory morbidities among them. Workers, especially loaders, were susceptible to work-related musculoskeletal diseases.

Aim:

To find out the morbidity profile and associated factors among rice mill workers.

Methodology:

A cross-sectional workplace-based study was conducted during July--September 2018 among 143 workers of two rice mills in Indas block, West Bengal. Workers, employed for at least 6 months in the rice mills and who gave informed written consent was interviewed using a predesigned pretested questionnaire and were clinically examined. Nonfasting capillary blood glucose estimation and spirometry were carried out. Workers contraindicated to spirometry were excluded.

Result:

Commonest morbidities were musculoskeletal discomfort (65%), hypertension (20.9%), and chronic respiratory morbidity (16.9%). No personal protective equipment (PPE) was used by these workers. Significant association of musculoskeletal discomfort was found with tobacco abuse (Adjusted Odds Ratio (AOR) =2.90), job of loader (AOR = 3.51), and central obesity (AOR = 3.39). Hypertension was significantly associated with increasing age (AOR = 1.06), and increasing body mass index (AOR = 1.17). Whereas increasing age (AOR = 1.08), working inside mill (AOR = 7.58), working more than 48 hours a week (AOR = 7.37) were significantly associated with chronic respiratory morbidity.

Conclusion:

Optimization of working hours, effective continuous use of PPE, and use of proper ventilation technology are recommended. Proper work placement, preplacement examination, and periodic health screening with spirometry are also needed.

Measurement of ϒ(1S) Elliptic Flow at Forward Rapidity in Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV

The first measurement of the ϒ(1S) elliptic flow coefficient (v_{2}) is performed at forward rapidity (2.5<y<4) in Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV with the ALICE detector at the LHC. The results are obtained with the scalar product method and are reported as a function of transverse momentum (p_{T}) up to 15  GeV/c in the 5%-60% centrality interval. The measured ϒ(1S)v_{2} is consistent with 0 and with the small positive values predicted by transport models within uncertainties. The v_{2} coefficient in 2<p_{T}<15  GeV/c is lower than that of inclusive J/ψ mesons in the same p_{T} interval by 2.6 standard deviations. These results, combined with earlier suppression measurements, are in agreement with a scenario in which the ϒ(1S) production in Pb-Pb collisions at LHC energies is dominated by dissociation limited to the early stage of the collision, whereas in the J/ψ case there is substantial experimental evidence of an additional regeneration component.

Investigations of Anisotropic Flow Using Multiparticle Azimuthal Correlations in pp, p-Pb, Xe-Xe, and Pb-Pb Collisions at the LHC

Measurements of anisotropic flow coefficients (v_{n}) and their cross-correlations using two- and multiparticle cumulant methods are reported in collisions of pp at sqrt[s]=13  TeV, p-Pb at a center-of-mass energy per nucleon pair sqrt[s_{NN}]=5.02  TeV, Xe-Xe at sqrt[s_{NN}]=5.44  TeV, and Pb-Pb at sqrt[s_{NN}]=5.02  TeV recorded with the ALICE detector. The multiplicity dependence of v_{n} is studied in a very wide range from 20 to 3000 particles produced in the midrapidity region |η|<0.8 for the transverse momentum range 0.2<p_{T}<3.0  GeV/c. An ordering of the coefficients v_{2}>v_{3}>v_{4} is found in pp and p-Pb collisions, similar to that seen in large collision systems, while a weak v_{2} multiplicity dependence is observed relative to nucleus-nucleus collisions in the same multiplicity range. Using a novel subevent method, v_{2} measured with four-particle cumulants is found to be compatible with that from six-particle cumulants in pp and p-Pb collisions. The magnitude of the correlation between v_{n}^{2} and v_{m}^{2}, evaluated with the symmetric cumulants SC(m,n) is observed to be positive at all multiplicities for v_{2} and v_{4}, while for v_{2} and v_{3} it is negative and changes sign for multiplicities below 100, which may indicate a different v_{n} fluctuation pattern in this multiplicity range. The observed long-range multiparticle azimuthal correlations in high multiplicity pp and p-Pb collisions can neither be described by pythia 8 nor by impact-parameter-Glasma, music, and ultrarelativistic quantum molecular dynamics model calculations, and hence, provide new insights into the understanding of collective effects in small collision systems.

Sun exposure and Vitamin D in rural India: A cross-sectional study

Background

Vitamin D deficiency/Vitamin D Insufficiency (VDI) is now recognized as a pandemic. Cutaneous exposure to ultraviolet-B causes photolysis of epidermal 7-dehydrocholesterol, converting it to pre-Vitamin D3 (precholecalciferol), which then undergoes isomerization to form the stable hormone Vitamin D3.

Objectives

The objectives of the study is to determine the status of Vitamin D level among the adults residing in a rural area of West Bengal and to find out the optimal cutoff of the sun exposure for Vitamin D sufficiency.

Methods

This study was a rural community based cross-sectional study. It was done from May 2016 to April 2017 among 197 adults residing in a rural block of West Bengal. Data were collected by interviewing the respondents with the help of a structured pre-tested pre-designed schedule. After interviewing, every individual was examined for height and weight and blood was collected for serum Vitamin 25-(OH) D. Receiver Operating Characteristic (ROC) curves were utilized to find out optimum cut-off for sun exposure using Youden's index. Binary logistic regression was performed to find out the associates of high sun exposure. All analysis was done using R.

Results

Overall VDI was found in 133 (67.5%). Among them, 102 (51.8%) were female. On ROC curve for veritable sun exposure for Vitamin D sufficiency, area under curve was 0.7841 which signifies veritable sun exposure as a good screening tool.

Conclusion

Proper information, education, and communication material regarding various aspects of sun exposure and Vitamin D should be prepared with due consultation of field experts and disseminated to increase awareness among the community.

War against tobacco: Where do we stand?

India has launched war against tobacco epidemic for the past few decades but with partial success; hence, challenges are still there which need to be identified and addressed for winning the battle. Targeted approach directed at motivating smoking cessation of female smokers, frequent changing of pictorial warnings depicting variety of health consequences in cigarette packets and devoid of logos and colors in conjunction with plain packaging, and display of toll-free number for quitting are expected to dissuade tobacco consumers to quit and save themselves from the devastating health, social, environmental, and economic consequences of tobacco consumption. Online reporting system for violating legal enforcements can also be implemented easily. Moreover, guidance from success stories of countries/states who have achieved smoke-free status along with concerted efforts such as innovative anti-tobacco campaigns, involvement of religious leaders in anti-tobacco propaganda, strict legislations, and overall strong political commitment would further aid in winning the war.

First Observation of an Attractive Interaction between a Proton and a Cascade Baryon

This Letter presents the first experimental observation of the attractive strong interaction between a proton and a multistrange baryon (hyperon) Ξ^{-}. The result is extracted from two-particle correlations of combined p-Ξ^{-}⊕p[over ¯]-Ξ[over ¯]^{+} pairs measured in p-Pb collisions at sqrt[s_{NN}]=5.02  TeV at the LHC with ALICE. The measured correlation function is compared with the prediction obtained assuming only an attractive Coulomb interaction and a standard deviation in the range [3.6, 5.3] is found. Since the measured p-Ξ^{-}⊕p[over ¯]-Ξ[over ¯]^{+} correlation is significantly enhanced with respect to the Coulomb prediction, the presence of an additional, strong, attractive interaction is evident. The data are compatible with recent lattice calculations by the HAL-QCD Collaboration, with a standard deviation in the range [1.8, 3.7]. The lattice potential predicts a shallow repulsive Ξ^{-} interaction within pure neutron matter and this implies stiffer equations of state for neutron-rich matter including hyperons. Implications of the strong interaction for the modeling of neutron stars are discussed.

Vitamin D Insufficiency Risk Score for Screening for Vitamin D Insufficiency

BACKGROUND AND AIMS

Vitamin D Deficiency/Insufficiency (VDD/VDI) is now recognized as a pandemic. Vitamin D is a versatile yet crucial factor which is vital for many metabolic functions in our body. Till now there is no screening tool for VDD/VDI. The aim of this study is to develop and validate a screening tool Vitamin D Insufficiency Risk Score (VDIRS).

METHODS

This study was a rural community based cross-sectional study. It was done during May 2016 to April 2017 among 197 adults residing in rural West Bengal. After a thorough literature review and discussion with the field experts, four characteristics (BMI, Physical activity, Daily Sun exposure, Diet) were considered for VDIRS. Data was collected after taking informed consent. After interviewing every individual was examined for height, weight and blood was collected for vitamin 25-(OH) D. Weights were given to VDIRS characteristic according to Adjusted Odds' Ratio. Receiver Operating Characteristics (ROC) curves were utilized to validate and find out optimum cut off for VDIRS using Youden's index for VDD/VDI with the use of R software.

RESULTS

Only 133 (67.5%) had Vitamin D insufficiency. On ROC curves for VDIRS for VDI and VDD, AUC was 0.83 and 0.77 which signifies VDIRS as a good screening and predictive tool. A score of VDIRS ≥14 had sensitivity of 78.2% and specificity of 75.0% for VDI.

CONCLUSION

Use of the VDIRS can make mass screening for undiagnosed VDI/VDD in India more cost effective. Researchers strongly believe and perceive a necessity of such validated score in the present scenario.

Family planning practices in couples with children affected by β-thalassemia major and its relationship with their education: An epidemiological study

BACKGROUND

Although prevention the birth of children with β-thalassemia major (β-TM) is an important health issue, it is rarely explored. With this background, the study was designed to find family planning practices and related factors of couples with children affected by β-TM.

MATERIALS AND METHODS

This was a cross-sectional, observational study, conducted among 324 parents with children affected by β-TM attending a tertiary care health facility in Eastern India. Data were analyzed using univariate and multivariable logistic regression using SPSS.

RESULTS

Of 324 parents, 89.5% were sexually active, 44.8% of which were currently using family planning method to prevent the birth of another child with the oral contraceptive pill most preferred (46.9%) followed by tubectomy (33.9%). Those who were sexually active, but not desirous of a child were 223, of which 41.7% had the unmet need for family planning with religious belief (41.9%) being the most predominant reason followed by unaware of methods (26.9%). In multivariable analysis, religion, caste, per capita monthly income, mothers' education level, and working status were significant predictors of unmet need for family planning adjusted with others.

CONCLUSIONS

Burden of unmet need for family planning among the study population was alarmingly high. Parents of the thalassemic children should be counseled in easily comprehensible local language to increase the rate of contraception among them.

Assessment of Poor Functional Status and its Predictors among the Elderly in a Rural Area of West Bengal

CONTEXT

Functional ability considered a proxy for healthy aging, not only related to mental and physical health but it also determines social well-being. Eliciting the determinants of functionality components among the elderly will assist in evolving with appropriate plans at both domiciliary and facility level to eliminate their sufferings and disabilities.

AIM

The aim of this study is to find out the magnitude of poor functional status among the elderly and its predictors.

MATERIALS AND METHODS

This is a community-based cross-sectional study conducted among 246 geriatric people in a rural area of West Bengal from August 2017 to December 2017; data were analyzed using the SPSS software (version 16.0. Chicago, SPSS Inc.). Logistic regression analysis was performed to find out the factors associated with poor functional status (activities of daily living [ADL] and instrumental ADL [IADL]).

RESULTS

The study concluded that 32.4% and 59.3% were dependent for basic ADL and IADL, respectively. Binary logistics showed people aged >70 years, female gender, less than primary level education, widowed/separated, who lived in the joint family, poorest percentile of economic status, who were depressed and who suffered from multimorbidity had increased odds of dependency for ADL and IADL. In multivariate logit regression, age >70 years and depression remained significant for ADL; in addition, marital status, education, and family type remained significant for IADL.

CONCLUSION

There should be a provision for community-based comprehensive geriatric health and disability assessment, as it enables older people to avert the illness at the early stage, to delay the onset of disabling diseases. This will ensure their participation in the upliftment of the society, and they thus will be less dependent on their progeny.

United Kingdom Diabetic Retinopathy Electronic Medical Record (UK DR EMR) Users Group: report 4, real-world data on the impact of deprivation on the presentation of diabetic eye disease at hospital services

AIM

To assess the impact of deprivation on diabetic retinopathy presentation and related treatment interventions, as observed within the UK hospital eye service.

METHODS

This is a multicentre, national diabetic retinopathy database study with anonymised data extraction across 22 centres from an electronic medical record system. The following were the inclusion criteria: all patients with diabetes and a recorded, structured diabetic retinopathy grade. The minimum data set included, for baseline, age and Index of Multiple Deprivation, based on residential postcode; and for all time points, visual acuity, ETDRS grading of retinopathy and maculopathy, and interventions (laser, intravitreal therapies and surgery). The main  outcome measures were (1) visual acuity and binocular visual state, and (2) presence of sight-threatening complications and need for early treatment.

RESULTS

79 775 patients met the inclusion criteria. Deprivation was associated with later presentation in patients with diabetic eye disease: the OR of being sight-impaired at entry into the hospital eye service (defined as 6/18 to better than 3/60 in the better seeing eye) was 1.29 (95% CI 1.20 to 1.39) for the most deprived decile vs 0.77 (95% CI 0.70 to 0.86) for the least deprived decile; the OR for being severely sight-impaired (3/60 or worse in the better seeing eye) was 1.17 (95% CI 0.90 to 1.55) for the most deprived decile vs 0.88 (95% CI 0.61 to 1.27) for the least deprived decile (reference=fifth decile in all cases). There is also variation in sight-threatening complications at presentation and treatment undertaken: the least deprived deciles had lower chance of having a tractional retinal detachment (OR=0.48 and 0.58 for deciles 9 and 10, 95% CI 0.24 to 0.90 and 0.29 to 1.09, respectively); in terms of accessing treatment, the rate of having a vitrectomy was lowest in the most deprived cohort (OR=0.34, 95% CI 0.19 to 0.58).

CONCLUSIONS

This large real-world study suggests that first presentation at a hospital eye clinic with visual loss or sight-threatening diabetic eye disease is associated with deprivation. These initial hospital visits represent the first opportunities to receive treatment and to formally engage with support services. Such patients are more likely to be sight-impaired or severely sight-impaired at presentation, and may need additional resources to engage with the hospital eye services over complex treatment schedules.

Azimuthal Anisotropy of Heavy-Flavor Decay Electrons in p-Pb Collisions at sqrt[s_{NN}]=5.02 TeV

Angular correlations between heavy-flavor decay electrons and charged particles at midrapidity (|η|<0.8) are measured in p-Pb collisions at sqrt[s_{NN}]=5.02  TeV. The analysis is carried out for the 0%-20% (high) and 60%-100% (low) multiplicity ranges. The jet contribution in the correlation distribution from high-multiplicity events is removed by subtracting the distribution from low-multiplicity events. An azimuthal modulation remains after removing the jet contribution, similar to previous observations in two-particle angular correlation measurements for light-flavor hadrons. A Fourier decomposition of the modulation results in a positive second-order coefficient (v_{2}) for heavy-flavor decay electrons in the transverse momentum interval 1.5<p_{T}<4  GeV/c in high-multiplicity events, with a significance larger than 5σ. The results are compared with those of charged particles at midrapidity and those of inclusive muons at forward rapidity. The v_{2} measurement of open heavy-flavor particles at midrapidity in small collision systems could provide crucial information to help interpret the anisotropies observed in such systems.

Genome-based taxonomic classification

Bacterial populations are routinely characterized based on microscopic examination, colony formation, and biochemical tests. However, in the recent past, bacterial identification, classification, and nomenclature have been strongly influenced by genome sequence information. Advances in bioinformatics and growth in genome databases has placed genome-based metadata analysis in the hands of researchers who will require taxonomic experience to resolve intricacies. To achieve this, different tools are now available to quantitatively measure genome relatedness within members of the same species, and genome-wide average nucleotide identity (gANI) is one such reliable tool to measure genome similarity. A genome assembly with a gANI score of <95% at the intraspecies level is generally considered indicative of a separate species. In this study, we have analysed 300 whole-genome sequences belonging to 26 different bacterial species available in the NCBI Genome database and calculated their similarity at the intraspecies level based on gANI score. At the intraspecies level, nine bacterial species showed less than 90% gANI and more than 10% of unaligned regions. We suggest the appropriate use of available bioinformatics resources after genome assembly to arrive at the proper bacterial identification, classification, and nomenclature to avoid erroneous species assignments and disparity due to diversity at the intraspecies level.

How frail are our elderly? An assessment with Tilburg frailty indicator (TFI) in a rural elderly population of West Bengal

Context:

“Frailty” is a multidimensional geriatric syndrome that increases the risk for adverse health outcomes, such as falls, hospitalization, increased morbidity, and mortality, among elderly persons.

Aim:

The objective of this study is to find out the proportion of frailty and its associates among elderly (aged ≥60 years) in a rural area of West Bengal.

Settings and Design:

It is a community-based cross-sectional observational study done during May–August 2018 among 165 elderly persons selected by systematic random sampling by probability proportionate to size method from three villages at the rural field practice area of our institute.

Materials and Methods:

Tilburg frailty indicator is used to measure frailty. An elderly is considered as frail if s/he scores ≥6 in this scale.

Statistical Analysis:

Data analysis is done by SPSS Version 16. The logistic regression is done to find out the associates of frailty.

Results:

Proportion of frailty is 38.8% (mean age ± SD: 67.03 ± 3.43 years) among the study subjects. Age, female gender, loss of spouse, illiteracy, economic dependency, no job/at home status, ≥2 chronic diseases are significantly associated with frailty in univariate logistic regression. In multivariable logistic regression, ≥2 chronic diseases [AOR: 8.4, CI: 4.6, 11.33] and illiteracy [AOR: 3.3, CI: 1.05, 9.8] retain their significance.

Conclusion:

Frailty should be recognized as a public health priority and awareness generation among elderly population for healthy ageing including self-motivation for proper management of their ailments should be emphasized for reduction of morbidity as well as for augmenting their quality of life.

Mobile phone involvement and dependence among undergraduate medical students in a Medical College of West Bengal, India

INTRODUCTION

Mobile phone dependence has become an emerging public health problem. This cross-sectional study was conducted to find out the mobile phone involvement and dependence among undergraduate medical students in a Medical College of West Bengal, India.

MATERIALS AND METHODS

A study was conducted at IQ City Medical College, Durgapur, District Burdwan, West Bengal, India, during July-August 2015 among 252 undergraduate medical students. Involvement and dependence were elicited by mobile phone involvement questionnaire (MPIQ) and mobile phone dependence questionnaire (MPDQ), respectively. Statistical Package for the Social Sciences (SPSS) software (version 19.0) was used for analysis.

RESULTS

About 14.9% of students were being highly involved with their mobile phone. The mean score of MPIQ was greatest in domain 5, i.e. euphoria followed by domain 2, i.e. behavioral salience and then domain 4, i.e. conflict with other activities. About 19.4% of males and 11.1% of females had high dependence. Mean MPDQ score was higher among males, though it was not significant statistically. Sex, total recharge, and total hours spent on mobile phone could explain between 2.2% and 3.8% variance of the presence of dependence in binary logistic regression. Total recharge (adjusted odds ratio 1.144) and total hours spent on mobile (adjusted odds ratio 1.135) were positively associated with the presence of dependence.

CONCLUSION

Many students were highly involved and dependent on mobile phone and they had already been experiencing some health-related problems. There is a need to identify students having high involvement and dependence so as to generate adequate awareness and plan educational or treatment interventions accordingly.

Safety of food served in Mid-Day Meal program: An in-depth study in upper primary schools of Kolkata

Introduction:

The Mid-Day Meal (MDM) program is the world's biggest supplementary school lunch program and is being implemented all over India for primary and upper primary school students. To continue a healthy program, personal hygiene of food handlers and beneficiaries should be well maintained.

Objective:

This study aims at examining the status of food safety measures including personal hygiene of food handlers and beneficiaries of MDM.

Methodology:

An institution-based observational study with cross-sectional design was conducted in upper primary schools (government, government-aided school) in Kolkata over a period of 2 years from November 2016 to October 2018. A sample of 52 schools from a total of 515 schools were then selected by simple random sampling. Analyses were conducted using SPSS software (SPSS Inc., released 2007 SPSS for Windows, version 16.0).

Results:

Among 52 schools, 53.8% were government-aided schools and 46.2% were government schools. There were significant differences in cleaning practice by cook-cum-helper (CCH) (χ² = 4.4, df = 1, P = 0.036), personal hygiene of CCH (χ² = 19.01, df = 1, P = 0.000) and beneficiaries (χ² = 9.3, df = 1, P = 0.002), practice during serving (χ² = 4.4, df = 1, P = 0.036), and use and storage of oils and condiments in MDM (χ² = 27.7, df = 1, P = 0.000) between government and government-aided schools.

Conclusion:

School authority should be concerned about maintaining proper hygiene. Adequate facilities and training program must be arranged for CCH to provide a healthy meal.

Exposure to indoor air pollution and its perceived impact on health of women and their children: A household survey in a slum of Kolkata, India

Background

One's house is believed to be the safest and the healthiest place to live in. Indoor air pollution (IAP) means the presence of unwanted substances in the indoor air at concentration toxic to health.

Objective

The objective of this study is to study the presence of IAP, its associated factors and impact on health of women residing in an urban slum of Kolkata, West Bengal, India.

Methods

It was a cross-sectional study done from January 2017 to March 2017 among 120 households of a slum. Data were collected using a pre-designed pre-tested schedule from the homemaker of the households. All analyses were conducted with R: A Language and Environment for Statistical Computing.

Results

About 60% households used kerosene as cooking fuel predominantly. Smoke from the neighbouring houses troubled 57.5% respondents. More than 60% houses were overcrowded and more than 70% houses were poorly ventilated. IAP-related symptoms such as irritation in the eye, suffocation, dry cough significantly correlated with the presence of IAP sources and its contributory factors. Of 120, 78 (65%) perceived the presence of IAP in their houses. Lower per capita income (PCI), ground floor, and joint family were found to have higher odds of sources of IAP. Younger age, lower PCI, and ground floor were found to be strongly associated with higher contributory factors of IAP.

Conclusion

The present study found that the majority of the households were exposed to IAP due to kerosene, neighborhood smoke while overcrowding and ill-ventilation accentuated it. Effective intervention with intersectoral coordination is the need of the hour.

Research submission: Some technicalities and vital links

Publishing allows the author to share with the world his original findings, reasoning, important breakthroughs and it also creates the avenue for mandates of promotion and career upliftment. In an endeavour to publish an article, the first vital technicality that the authors face is selection of an appropriate journal. There has been steady increase in the number of predatory publishers and journals. Knowledge of the different publication models, websites to check valid open access journals and reliance on certain reputable publishing houses may actually guide the authors in selecting legitimate journals. Open Researcher and Contributor ID (ORCID ID) or Researcher ID is required during submission of articles. ResearchGate, Mendeley or Scholar Universe are useful sites to collaborate and disseminate research publication in an effective manner. Search Engine Optimization (SEO) is another vital technicality that needs to be adopted by the authors before submission of the research work for publication to ensure higher visibility of the published research article in the academic community and increase citations. Thorough understanding of the publication process, following simple technicalities of manuscript submission and establishing vital links in the post publication phase is some of the useful guidelines for shaping up the success story of the research.

In silico characterization of functional single nucleotide polymorphisms of folate pathway genes

Folate metabolism genes are pivotal to critical biological processes and are related to several conditions, including developmental, cognitive, and cardiovascular anomalies. A systematic catalog of genetic polymorphisms in protein coding regions, regulatory transcription factor binding sites, and miRNA binding sites associated with folate pathway genes may contribute to personalized medicine. We performed a comprehensive computational survey of single nucleotide polymorphisms (SNPs) of folate pathway genes to highlight functional polymorphisms in the coding region, transcription factor binding sites, and miRNAs binding sites. Folate pathway genes were searched through PubMed and Kyoto Encyclopedia of Genes and Genomes pathway databases. SNPs were identified and characterized using the University of California, Santa Cruz genome browser and SNPnexus tool. Functional characterization of nonsynonymous SNPs (nsSNPS) was performed using bioinformatics tools, and common deleterious nsSNPs were identified. We identified 48 genes of folate pathway containing 287 SNPs in the coding regions. Out of these SNPs, rs5742905, rs45511401, and rs1801133 were predicted to be deleterious through four different bioinformatics tools. Three-dimensional structures of two proteins with and without deleterious nsSNPs were predicted by SWISSPDB viewer and SuperPose. Besides, a total of 237 SNPs was identified in transcription factor binding sites using the Genomatix software suite and six miRNA target site SNPs using miRNASNP. This systematic and extensive in silico analysis of functional SNPs of folate pathway may provide a foundation for future targeted mechanistic, structure-function, and genetic epidemiological studies.

D-Meson Azimuthal Anisotropy in Midcentral Pb-Pb Collisions at sqrt[s]_{NN}=5.02 TeV

The azimuthal anisotropy coefficient v_{2} of prompt D^{0}, D^{+}, D^{*+}, and D_{s}^{+} mesons was measured in midcentral (30%-50% centrality class) Pb-Pb collisions at a center-of-mass energy per nucleon pair sqrt[s_{NN}]=5.02  TeV, with the ALICE detector at the LHC. The D mesons were reconstructed via their hadronic decays at midrapidity, |y|<0.8, in the transverse momentum interval 1<p_{T}<24  GeV/c. The measured D-meson v_{2} has similar values as that of charged pions. The D_{s}^{+} v_{2}, measured for the first time, is found to be compatible with that of nonstrange D mesons. The measurements are compared with theoretical calculations of charm-quark transport in a hydrodynamically expanding medium and have the potential to constrain medium parameters.

Tobacco-related morbidity and nicotine dependence: An experience in an urban slum of Burdwan district, West Bengal, India

Tobacco use causes many diseases irrespective of age and sex. More the addiction, more is the occurrence of morbidity in terms of frequency and severity. This community-based study was conducted to find out any relationship between the morbidity associated with tobacco use and nicotine dependence. In an urban slum - Alamganj, district Burdwan, West Bengal, India, from January to October 2012 among 128 current adult tobacco users using Fagerström test for nicotine dependence (FTND) questionnaire. Tobacco users were maximally suffering from chronic obstructive pulmonary disease (COPD) (27.27%), gastritis (25.45%), and leukoplakia (25.45%). For individual diseases, the difference in FTND score was significantly high in cases of gastritis, hypertension, and COPDs. All types of morbidity were more common in the group of high nicotine dependence. FTND score can be suitably used to assess nicotine dependence of the tobacco users, who can be counseled accordingly to reduce the tobacco-related morbidity and mortality.

Vitamin D status among women aged 40 years and above in a rural area of West Bengal: A community-based study

Introduction:

Vitamin D deficiency is a recognized pandemic. Even in a tropical country like India, where there is plentiful sunshine, vitamin D deficiency is widely prevalent. Adult females, particularly those above the age of 40, are mostly affected because vitamin D determines the pattern of post-menopausal bone loss and age-related osteoporosis.

Methods:

A community-based cross-sectional study was conducted from April–December 2017 among 194 women aged 40 years and above residing in the village of Singur, West Bengal. For this study, multistage random sampling method was used. Each respondent was interviewed using a structured schedule to collect data on sociodemographic characteristics, dietary pattern, their daily sun exposure, tobacco use, and morbidity profile. Individuals with 25OH vitamin D <30ng/ml were said to have vitamin D insufficiency (VDI). Data entry and analysis was done using SPSS version 16.0.

Results:

Out of 194 participants, 70.6% had VDI (Vitamin D deficient-19.6%, Vitamin D insufficient-51.0%). Mean (SD) age of the participant was 56.9 (8.9) years. Mean (SD) duration of daily sun exposure was 138.5 (59.2) minutes. 74 (38.1%) had overweight/obesity. Only 73 (37.6%) had adequate diet. Test results revealed low SES, decreasing duration of daily sun exposure, diabetes, overweight/obesity, and inadequate diet as significant predictors of VDI, explaining 39.3% of the variance with model fit.

Conclusion:

The study has identified factors associated with VDI among the study participants. Emphasis on promoting consumption of vitamin D rich food and with vitamin D supplements, outdoor activities to increase sun exposure, maintaining optimum body weight, and strictly adhering to diabetes control will help alleviate the problem at large.

A Cross Sectional Study on Visual Health among Women aged 18-59 years residing in a Slum of Kolkata, West Bengal

Introduction: Visual impairment has a silent chronic course which has a significant impact on the quality of life but is often a preventable community problem. Comprehensive assessment of ophthalmic outcomes should include not only the objective measurement but also the subjective perception of vision loss on vision function. Aim: To estimate the proportion of visual impairment and perceived visual functioning and also to find out the factors, if any associated with it, among women aged18-59 years in a slum of Kolkata. Methodology: It was a community-based cross-sectional study conducted among 153 women aged 18-59 years residing in a slum of Chetla, which is under the urban field practice area of All India Institute of Hygiene & Public Health, Kolkata within 3 months of duration (Mar - May 2017). Results: In the present study, 49(32%) study subjects were visually impaired among which 3(2%) were blind. 42.4% of study subjects’ perceived poor visual function. Logistic regression showed aged 40 years and above, below and primary educational level, non-working, who had eye checkup and diabetic had higher odds of visual impairment and perceived poor visual function whereas after adjustment, diabetic status lost its significance. Conclusion: Eye care programmes in our country still have curative approach; it must shift towards preventive approach.

Assessment of self-care practices among hypertensive patients: a clinic based study in rural area of Singur, West Bengal

Background: Hypertension, also known as high blood pressure is a global public health concern. It is an important modifiable risk factor for cardiovascular disease and stroke. It remains silent, being generally asymptomatic during its clinical course and it accounts for a large proportion of cardiovascular deaths; lifestyle modification is the first line of intervention for all patients with hypertension, yet it was never been empirical. The aim of the study was to assess the pattern of self-care practices, if any and also to find out the factors associated with it, among the hypertensive patients in the outpatient department. Methods: A clinic-based, observational, cross-sectional study was conducted at health center under RHU & TC, Singur, which is the rural field practice area of All India Institute of Hygiene and Public Health, Kolkata among 124 hypertensive subjects. Binary logistic regression was done to find out the factors associated with the self-care practices using SPSS software. Results: In the present study, 62.9% of study participants suffering from hypertension had unfavourable self-care practices. Logistic regression showed age above 60 years (OR-3.1), primary level education (OR-5.6), poor socio economic status (OR-2.4), widow/separated (OR-3.3) and people with self-perceived poor health status (OR-2.8)had significant association with unfavourable self-care practices. After adjusting with other variables, age (AOR-2.3) and education (AOR-3.8) remained significant predictor of outcome. Conclusions: The findings revealed that the self-care practices among hypertensive patients were unfavourable in rural area. This calls for a deep need in increasing the awareness about healthy lifestyle among hypertensive patients. This study provides key elements to affect policy changes and social interventions. 

J/ψ Elliptic Flow in Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV

We report a precise measurement of the J/ψ elliptic flow in Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV with the ALICE detector at the LHC. The J/ψ mesons are reconstructed at midrapidity (|y|<0.9) in the dielectron decay channel and at forward rapidity (2.5<y<4.0) in the dimuon channel, both down to zero transverse momentum. At forward rapidity, the elliptic flow v_{2} of the J/ψ is studied as a function of the transverse momentum and centrality. A positive v_{2} is observed in the transverse momentum range 2<p_{T}<8  GeV/c in the three centrality classes studied and confirms with higher statistics our earlier results at sqrt[s_{NN}]=2.76  TeV in semicentral collisions. At midrapidity, the J/ψ  v_{2} is investigated as a function of the transverse momentum in semicentral collisions and found to be in agreement with the measurements at forward rapidity. These results are compared to transport model calculations. The comparison supports the idea that at low p_{T} the elliptic flow of the J/ψ originates from the thermalization of charm quarks in the deconfined medium but suggests that additional mechanisms might be missing in the models.

Development of 100 Mo -containing scintillating bolometers for a high-sensitivity neutrinoless double-beta decay search

This paper reports on the development of a technology involving 100 Mo -enriched scintillating bolometers, compatible with the goals of CUPID, a proposed next-generation bolometric experiment to search for neutrinoless double-beta decay. Large mass ( ∼ 1 kg ), high optical quality, radiopure 100 Mo -containing zinc and lithium molybdate crystals have been produced and used to develop high performance single detector modules based on 0.2-0.4 kg scintillating bolometers. In particular, the energy resolution of the lithium molybdate detectors near the Q-value of the double-beta transition of 100 Mo (3034 keV) is 4-6 keV FWHM. The rejection of the α -induced dominant background above 2.6 MeV is better than 8 σ . Less than 10 μ Bq/kg activity of 232 Th ( 228 Th ) and 226 Ra in the crystals is ensured by boule recrystallization. The potential of 100 Mo -enriched scintillating bolometers to perform high sensitivity double-beta decay searches has been demonstrated with only 10 kg × d exposure: the two neutrino double-beta decay half-life of 100 Mo has been measured with the up-to-date highest accuracy as T 1 / 2 = [6.90 ± 0.15(stat.) ± 0.37(syst.)] × 10 18 years . Both crystallization and detector technologies favor lithium molybdate, which has been selected for the ongoing construction of the CUPID-0/Mo demonstrator, containing several kg of 100 Mo .

Anomalous Evolution of the Near-Side Jet Peak Shape in Pb-Pb Collisions at sqrt[s_{NN}]=2.76 TeV

The measurement of two-particle angular correlations is a powerful tool to study jet quenching in a p_{T} region inaccessible by direct jet identification. In these measurements pseudorapidity (Δη) and azimuthal (Δφ) differences are used to extract the shape of the near-side peak formed by particles associated with a higher p_{T} trigger particle (1<p_{T,trig}<8  GeV/c). A combined fit of the near-side peak and long-range correlations is applied to the data allowing the extraction of the centrality evolution of the peak shape in Pb-Pb collisions at sqrt[s_{NN}]=2.76  TeV. A significant broadening of the peak in the Δη direction at low p_{T} is found from peripheral to central collisions, which vanishes above 4  GeV/c, while in the Δφ direction the peak is almost independent of centrality. For the 10% most central collisions and 1<p_{T,assoc}<2  GeV/c, 1<p_{T,trig}<3  GeV/c a novel feature is observed: a depletion develops around the center of the peak. The results are compared to pp collisions at the same center of mass energy and ampt model simulations. The comparison to the investigated models suggests that the broadening and the development of the depletion is connected to the strength of radial and longitudinal flow.

Is Ramadan Fasting Cardio-protective? A Study in a Village of West Bengal

Background: Islam is the second largest religion of the World (23%) and Muslims are the second largest majority of Indian Republic (14.3%). Ramadan is the ninth and holiest month(Hijra) of the 12-month Islamic calendar during which Muslims fast from dawn to dusk each day maintaining certain rules (consuming food/drink once, avoiding smoking and sexual activity, as well as impure thoughts, words and immoral behavior). It is observed by Muslims as a month of fasting to commemorate the first revelation of the Qur'an to Muhammad. Aims & Objectives: To evaluate the effect of Ramadan on cardio-metabolic profile among adult Muslims residing in rural West Bengal. Methods and Materials: The present study was a longitudinal community based study done among 43 Muslims residing in a village of West Bengal during 6thJune to 7th July 2016. Cardio-metabolic profile (physical activity, diet, BMI, blood pressure, blood lipids and glucose) were assessed before, during and after Ramadan. Results: There was a significant reduction in VLDL and TG level while significant elevation in HDL level along with the reduction in Framingham risk score after fasting. All the anthropometric measurements along with blood pressure reduced significantly after Ramadan with significant reduction in intake of all micro-nutrients during Ramadan. However physical activity also reduced significantly during Ramadan. Conclusion: Our study had found no detrimental effects of Ramadan fasting on the contrary has an overall beneficial effect on cardiovascular profile was observed.
