Burden of falls among elderly persons in India: A systematic review and meta-analysis

Background

. Falls are one of the leading causes of death and disability among elderly persons. In India, there is paucity of data on the prevalence of falls, particularly among community-dwelling elderly persons. To estimate healthcare costs related to falls and formulation of fall prevention strategies, there is a need of reliable estimates of magnitude of falls. We aimed to provide a community-based pooled estimate of the burden of falls among elderly persons in India.

Methods

. A systematic literature search was done manually as well as electronically through PubMed, Google Scholar, Cochrane library, IndMed, Embase and WHO databases. Community-based original studies conducted in India were included. No restriction for the date was used. Meta-analysis was done using the random effects model.

Results

. Sixteen studies were included in the review and meta-analysis. These studies included a total of 14 844 elderly persons, of which 2707 reported falling. The pooled prevalence of falls was found to be 31% (95% CI 23%-39%). There was significant heterogeneity between the studies (I² = 98.08%, p<0.01).

Conclusion

. There is a high prevalence of falls among elderly persons in India. However, the available studies have considerable methodological variations and are of limited quality. Realistic estimates are required for designing programmes for prevention of falls and for rehabilitation.

Clinical and Molecular Disease Spectrum and Outcomes in Patients with Infantile-Onset Pompe Disease

OBJECTIVES

To evaluate the clinical and molecular spectrum, and factors affecting clinical outcome of patients in India diagnosed with infantile-onset Pompe disease (IOPD).

STUDY DESIGN

In this multicenter, cross-sectional study, we evaluated the records of 77 patients with IOPD to analyze their clinical course, outcomes, and factors influencing the outcomes.

RESULTS

Of the 77 patients with IOPD, phenotype data were available in 59; 46 (78%) had the classic phenotype. Overall, 58 of 77 (75%) and 19 of 77 (25%) patients were symptomatic before and after age 6 months, respectively. Alpha-glucosidase gene variant analysis available for 48 patients (96 alleles) showed missense variants in 49 alleles. Cross-reactive immunologic material (CRIM) status could be determined or predicted in 44 of 48 patients. In total, 32 of 44 patients (72%) were CRIM-positive, and 12 of 44 patients (27%) were CRIM-negative. Thirty-nine cases received enzyme-replacement therapy (ERT), alglucosidase alfa, and 38 patients never received ERT. Median age at initiation of ERT was 6.5 months. Response to ERT was better in babies who had CRIM-positive, non-classic IOPD.

CONCLUSIONS

This study highlights the clinical spectrum of IOPD in India and provides an insight on various factors, such as undernutrition, feeding difficulties, and recurrent respiratory infection, as possible factors influencing clinical outcomes in these patients. The study also reiterates the importance of raising awareness among clinicians about the need for early diagnosis and timely treatment of IOPD.

Prevalence of pulmonary tuberculosis in India: A systematic review and meta-analysis

The Revised National Tuberculosis Control Program was started in India in 1997. There has been no nationwide survey to assess the prevalence of pulmonary tuberculosis. We aimed to conduct a systematic review and meta-analysis of published literature to provide an estimate of the prevalence of pulmonary tuberculosis in India. Several databases including Medline, Embase, Scopus, the Cochrane Library, Web of Science, and Google Scholar were searched for studies published between January 1, 1997, and December 31, 2018, which reported the prevalence of pulmonary tuberculosis. Community-based cross-sectional studies conducted among population aged 15 years and above were included. Summary estimates were calculated using random effects models. We identified 13 articles with 16 individual studies having screened 961,633 individuals for pulmonary tuberculosis. The pooled prevalence of bacteriologically positive pulmonary tuberculosis was 295.9 (95% confidence interval: 201.1-390.6) per 100,000 population. The prevalence was higher among males than females and in rural areas compared to urban areas. The pooled prevalence of culture-positive pulmonary tuberculosis (277.8/100,000 population) was higher than smear-positive pulmonary tuberculosis (196.6/100,000 population). The pooled prevalence of bacteriologically positive pulmonary tuberculosis in sensitivity analysis was 186.6/100,000 population. In all these estimates, heterogeneity remained high and significant publication bias was observed. The prevalence of pulmonary tuberculosis varied based on sex and distribution of population in rural and urban areas. There is a need of nationwide population-based survey to estimate the burden of tuberculosis to inform control measures and facilitate monitoring and evaluation.

Use of spectacles for distance vision: coverage, unmet needs and barriers in a rural area of North India

Background

Uncorrected refractive errors contribute enormously to the burden of avoidable visual impairment worldwide. There is a huge disparity in different parts of the globe in context to spectacle coverage for distance vision. This study was undertaken with objectives of determining prevalence of spectacle coverage, unmet needs and associated factors among adults in a rural community of north India.

Methods

A community-based cross-sectional study was carried out within selected clusters of Jhajjar district of Haryana. All participants aged > 15 years underwent visual acuity assessment by LogMAR “E” screening chart. Participants with presenting visual acuity < 6/12 in any eye and all current spectacle users underwent detailed ophthalmic examination and refraction. Additional details about spectacles, barriers for their use and willingness to pay for them were collected. Participants with met and unmet need for spectacle use at visual acuity > 6/12 was computed. These are reported as proportions with 95% confidence intervals. Associated factors with unmet need were determined using bivariable and multivariable logistic regression analysis.

Results

A total of 6910 participants were examined. The current spectacle use was 7.5% (95% Confidence Interval CI: 6.5, 8.7). The spectacle coverage was found in 33.3% (95% CI: 30.0, 36.7) participants among those in need. The unmet need was found in 10.8% of participants (95% CI: 10.1, 11.6). On multivariable analysis, odds of unmet need was associated with age, gender, level of education and marriage status. The most common barrier for refractive correction was lack of perceived need for refraction and its correction.

Conclusion

There is substantial unmet need for distance vision spectacles in this population. It is imperative that multi-component intervention be implemented to improve spectacle coverage in this rural north Indian setting.

Prevalence of blindness in India: A systematic review and meta-analysis

BACKGROUND

The National Programme for Control of Blindness and Visual Impairment modified the definition of blindness in 2017 in line with the internationally accepted definition. We did a systematic review and meta-analysis to compute pooled estimate of blindness in India among adults aged 50 years and above by using recent and old definitions of blindness.

METHODS

We retrieved population-based studies/surveys reporting the prevalence of blindness using recent (presenting vision <3/60 better eye) and previous (presenting vision <6/ 60 better eye) definitions in India during 1990-2017 from key search engines and grey literature. Two authors did an independent literature search and extracted relevant information. Pooled prevalence estimates were computed using Stata 12.0 by using the random effects model. Forest and funnel plots were generated. Stratification of results was also performed using two time periods: 1995-2005 and 2006-17.

RESULTS

A total of 18 published articles/reports were included for recent and 20 for previous definitions of blindness, involving 211 502 participants. The pooled prevalence (95% confidence interval [CI]) obtained for recent and previous definitions of blindness in India was found to be 6.11% (5.07%-7.14%) and 9.91% (8.57%-11.25%), respectively. The stratified pooled prevalence (95% CI) from rapid surveys was 4.81% (3.26%-6.35%) and 4.68% (2.91%-6.46%) for studies published during 1995-2005 and 2006-17, respectively, using the new definition. The corresponding figures for comprehensive surveys were 9.22% (95% CI 6.48%-11.96%) for the period 1995-2005 and 3.81% (95% CI 2.76%-4.84%) for the period 2006-17.

CONCLUSION

There is a decrease in the prevalence of blindness in India using recent and previous definitions and a declining trend over time. High quantum of blindness remains an unfinished public health agenda for implementing programmes in larger populations to reduce its burden.

Relationship between height and arm span of elderly persons in an urban colony of New Delhi

Anthropometric changes take place with increasing age. Progressive loss of height makes it difficult to use height for calculation of body mass index in nutritional screening of elderly persons. There is a need to find other alternative methods which could be used as proxy measurements of height in them. To assess the relationship of height and arm span and among elderly persons. A community-based cross-sectional study was conducted among elderly persons in urban colony of Delhi. Height and arm span of persons aged 60 years and above (n = 711) were measured according to standard methods. Correlation between arm span and height was calculated. The mean arm span was seen to be more than the mean height in all age-groups and both sexes. There was a linear relationship between height and arm-span in all age-groups. There was a strong correlation between arm span and height in all age groups. Arm span could be used instead of height as an alternative in the conventional body mass index in elderly persons.

Sleep Quality Assessment of Adolescents Residing in an Urban Resettlement Colony, New Delhi, India

Background

Sleep is essential for physical and psychological development of children as well as adolescents. Poor sleep has been noted to lead to poor diet, obesity, stunted growth, mental health issues, and substance abuse. Despite the knowledge regarding the importance of sufficient sleep, the prevalence of insufficient sleep has been noted to increase among children and adolescents.

Objective and Aim

The aim of the study was to determine the prevalence of poor sleep quality among adolescents of an urban resettlement colony and to evaluate the association of poor sleep quality with the correlates.

Materials and Methods

A community-based cross-sectional study was conducted including 620 adolescents aged 10-19 years, in an Urban Resettlement Colony, Dakshinpuri Extension, New Delhi. A self-reported interview was conducted with the pretested, semi-structured interview schedule. The interview focused on sociodemographic variable, sleep quality using Pittsburgh sleep quality index, Perceived stress scale, screen time, and anthropometric measurements.

Results

The mean of Pittsburgh sleep quality index total score was 2.3 (standard deviation = 1.9). Among the adolescents, 7.3% of them were found to be poor sleepers. Poor sleep quality was observed to be higher during school days as compared to vacation (9.3%, 6.5%, respectively). Adolescents of age group equal to and > 15 years have higher odds of having poor sleep quality than those younger than 15 years of age (odds ratio = 4.9; 95% confidence interval: 2.2, 10.8).

Conclusion

Significant difference in sleep duration was noted among adolescents of age ≥15 years as compared to the younger group in the present study.

R, Kalaivani M, Nongkynrih B, Kant S, Gupta SK. Disability and its association with sociodemographic factors among elderly persons residing in an urban resettlement colony, New Delhi, India

Disability prevents an individual from performing to the fullest potential. It is multidimensional. Disability may be physical, mental, social, personal, and environmental or a combination of these. The elderly experience an increased burden of disability, especially in areas where there are limited resources and rapid urbanization. Comparison of reported disability is difficult because several definitions and scales are in use. We used the World Health Organization Disability Assessment Schedule version 2.0 (WHODAS 2.0) to study the prevalence of disability, and its association with sociodemographic factors among elderly persons residing in an urban resettlement colony, New Delhi, India. The WHODAS 2.0 provides continuous summary scores, where higher scores indicate higher disability, and vice versa. Elderly persons aged 60 years and above were selected by simple random sampling in this community-based cross-sectional study. Trained interviewers administered the semi-structured interview schedule and WHODAS 2.0. The prevalence of disability was 7.4% (5.8% - 9.3%) among the 931 participants. The prevalence was higher among females than males. Female sex, elderly aged 70 years and above, and those who were illiterate had increased risk of higher disability scores. Participants who were in government or private service had 50% decreased risk of having higher disability scores. The burden of disability was high among elderly persons residing in this resettlement colony. Community-based holistic interventions are required to mitigate the disability, and to improve the functioning of elderly persons.

Concordance of glycaemic and cardiometabolic traits between Indian women with history of gestational diabetes mellitus and their spouses: an opportunity to target the household

AIMS/HYPOTHESIS

The aim of this study was to investigate the concordance of dysglycaemia (prediabetes or diabetes) and cardiometabolic traits between women with a history of gestational diabetes mellitus (GDM) and their spouses.

METHODS

Using hospital medical records, women with GDM (diagnosed between 2012 and 2016) and their spouses were invited to participate in the study and to attend a scheduled hospital visit in a fasting state. Sociodemographic, anthropometric and medical data were collected, and a 75 g OGTT with serum insulin estimation, HbA_1c measurement and fasting lipid profile were performed at the visit. Prediabetes and diabetes were defined using ADA criteria and the metabolic syndrome was defined using IDF criteria.

RESULTS

A total of 214 couples participated in the study. Women were tested at a mean ± SD age of 32.4 ± 4.6 years and median (quartile [q]25-q75) of 19.5 (11-44) months following the index delivery, while men were tested at a mean ± SD age of 36.4 ± 5.4 years. A total of 72 (33.6%) couples showed concordance for dysglycaemia, while 99 (46.3%) and 51 (23.8%) couples were concordant for overweight/obesity and the metabolic syndrome, respectively. A total of 146 (68.2%) couples showed concordance for any of the above three factors. The presence of dysglycaemia in one partner was associated with an increased risk of dysglycaemia in the other partner (OR 1.80 [95% CI 1.04, 3.11]). Similarly, being overweight/obese (OR 2.19 [95% CI 1.22, 3.93]) and presence of the metabolic syndrome (OR 2.01 [95% CI 1.16, 3.50]) in one partner was associated with an increased risk of these conditions in the other partner. Both women and men were more likely to have dysglycaemia if they had a partner with dysglycaemia. Women with a partner with dysglycaemia had a significantly higher BMI, waist circumference and diastolic BP, and a significantly higher probability of low HDL-cholesterol (<1.29 mmol/l) and the metabolic syndrome compared with women with a normoglycaemic partner. No such differences were observed for men with or without a partner with dysglycaemia.

CONCLUSIONS/INTERPRETATION

The high degree of spousal concordance found in this study suggests social clustering of glycaemic and cardiometabolic traits among biologically unrelated individuals. This provides us with an opportunity to target the behavioural interventions at the level of the 'married couple', which may be a novel and cost-effective method of combating the current diabetes epidemic.

Genetic polymorphisms associated with obesity and non-alcoholic fatty liver disease in Asian Indian adolescents

Background The objective of this study was to investigate the association of polymorphisms in four genes, tumor necrosis factor-α (TNFA), patatin-like phospholipase domain containing 3 (PNPLA3), adiponectin (ADIPOQ) and apolipoprotein C3 (APOC3), with obesity and non-alcoholic fatty liver disease (NAFLD) in Asian Indian adolescents. Methods In this case-control study, 218 Asian Indian adolescents with overweight/obesity and 86 lean healthy adults without fatty liver were enrolled. Hepatic steatosis was assessed and graded by ultrasonography (USG). Serum insulin, lipids, alanine aminotransferase (ALT), aspartate aminotransferase (AST), TNF-α, adiponectin and apolipoprotein C3 were measured and genotyping was done. Frequencies of variant and wild genotypes in all adolescents and in the subgroups without steatosis, with grade 1 steatosis and with grade 2 or 3 steatosis were compared to those in the controls. The frequencies were also compared in the overweight adolescents with grade 2 or 3 steatosis and without steatosis. Results Variant genotypes of polymorphisms -863 C > A and -1031 T > C of the TNFA gene, 455 T > C of the APOC3 gene and the wild type of +276 G > T of the ADIPOQ gene were associated with obesity with odds ratios (OR, 95% confidence interval [CI]) of 2.5 (1.5-4.4), 2.5 (1.5-4.2), 2.0 (1.1-3.6) and 2.5 (1.4-5.0), respectively. Polymorphisms 455 T > C of APOC3 and rs738409 C > G of PNPLA3 were associated with NAFLD. Fasting insulin and triglycerides (TG) were higher in the adolescents with homozygous variant polymorphisms -1031 T > C of TNFA and 455 T > C of APOC3 genes, respectively. Conclusions Several polymorphisms were noted to have a significant association with obesity and NAFLD in Asian Indian adolescents.

Gender differences in blindness, cataract blindness and cataract surgical coverage in India: a systematic review and meta-analysis

BACKGROUND

The magnitude of blindness is unevenly distributed worldwide. This systematic review aimed to study gender differences in the prevalence of blindness, cataract blindness and cataract surgical coverage in India among persons aged 50 years and above.

METHODS

Literature search was carried out in the Medline, Web of Science, Google Scholar, EMBASE and Trip databases. Data were abstracted and risk of bias was assessed for the selected full-text articles. Pooled prevalence, ORs and risk differences were synthesised by meta-analyses.

RESULTS

22 studies were included in the systematic review. The pooled prevalence of blindness obtained for men was 4.17% and that for women was 5.68%. Women had 35% higher odds of being blind (OR 1.35, 95% CI 1.08 to 1.62) and 69% higher odds of being cataract blind (OR 1.69, 95% CI 1.44 to 1.95). Women had a 27% lower odds of getting cataract surgery (OR 0.73, 95% CI 0.45 to 1.01). In women, around 35% of the prevalence of blindness and 33% of the prevalence of cataract blindness are attributable to their gender.

CONCLUSION

Marked gender differences in blindness, cataract blindness and cataract surgical coverage were seen in India, with the odds being unfavourable for women. Interventions implemented for reduction of blindness, including cataract blindness, need to consider these gender differentials in the Indian context. Further research is needed to ascertain the reasons for these differences and devise interventions to reduce these differences in order to tackle the magnitude of avoidable blindness in India.

Development and validation of a questionnaire for a survey on perioperative fasting practices in India

BACKGROUND AND AIMS

Perioperative fasting guidelines have been published and updated to standardise practices. Hence, Indian Society of Anaesthesiologists decided to conduct a survey to assess the fasting practices and the food habits across India, which would be subsequently used for developing preoperative fasting guidelines for the Indian population. We detail and discuss herewith the content validity of the questionnaire developed for the survey.

METHODS

Thirty-six questions related to perioperative fasting practices were framed based on the collected evidence and relevance to regional diet and concerns. Subsequently, an information sheet was prepared and sent to 10 experts to grade each question. The responses were tabulated, and item-wise content validity index (I-CVI), scale-wise content validity index (S-CVI) and modified kappa statistic were calculated in Microsoft Excel^™ sheet.

RESULTS

Seven of the 10 experts completed the assessment and grading as per the instructions provided and submitted a completed proforma. S-CVI for relevance, simplicity, clarity and ambiguity was 0.72, 0.86, 0.72 and 0.72, respectively. S-CVI/average or average congruency percentagewas 0.95, 0.97, 0.95 and 0.95 for relevance, simplicity, clarity and ambiguity, respectively. Question 2 received an I-CVI of 0.71 in terms of clarity and question 23 received an I-CVI of 0.71. They were modified as persuggestions of the experts.

CONCLUSION

We conclude that our questionnaire designed to ascertain the preoperative fasting practices for a surveymet the content validity criteria both by qualitative and quantitative analyses.

An Optimal Capillary Screen Cut-off of Thyroid Stimulating Hormone for Diagnosing Congenital Hypothyroidism: Data from a Pilot Newborn Screening Program in Delhi

OBJECTIVE

To determine an appropriate cut-off of capillary Thyroid stimulating hormone (TSH) for congenital hypothyroidism.

STUDY DESIGN

Cross-sectional.

PARTICIPANTS

174,000 neonates born in different hospitals of Delhi, India, from November 2014 to October 2016.

MAIN OUTCOME MEASURES

Correlation between initial and repeat capillary TSH level and subsequent venous free thyroxine (fT4) level.

RESULTS

102 newborns with initial/ repeat capillary TSH level of ≥20 mIU/L (n=174) were confirmed to have congenital hypothyroidism at mean (SD) age of 5 (4) days. A good correlation between capillary TSH level and confirmatory venous fT4 level and postnatal age of sampling was obtained (r -0.6, -0.4). The area under the ROC curve (AUC) was 0.81 (95%CI 0.75 to 0.88), indicating referral capillary TSH level of 20 mIU/L to be a good predictor of subsequent high venous TSH level.

CONCLUSIONS

A cut off of ≥20 mIU/L for capillary TSH screening beyond 24 hours of life is optimal in the Indian setting for deciding further recall and workup, keeping a balance between sensitivity and recall rate.

Comparison of ferric Carboxymaltose and iron sucrose complex for treatment of iron deficiency anemia in pregnancy- randomised controlled trial

BACKGROUND

To evaluate the efficacy and safety of intravenous Ferric Carboxymaltose. (FCM) in comparison with intravenous Iron sucrose complex (ISC) for treatment of iron deficiency anemia in pregnancy.

METHODS

A randomized clinical trial was conducted from (January 2016-August 2017). at a tertiary hospital. Pregnant women diagnosed with moderate to severe iron deficiency anaemia were screened for the study. One hundred patients were randomized to receive either intravenous FCM or ISC. Primary outcome was rise in hemoglobin (Hb) from baseline after 12 weeks. Secondary outcomes were change in RBC indices, serum iron studies, improvement in fatigue scores, number of visits and perinatal outcome.

RESULTS

Mean rise in Hb at 12 weeks was significantly higher in FCM group (29 g/L vs 22 g/L; p value < 0.01). FCM was associated with greater improvement in fatigue scores. Number of visits were significantly less in FCM group. No serious adverse events were noted in either group.

CONCLUSION

Treatment with FCM resulted in rapid replenishment of iron stores in pregnant women with significantly higher Hb rise over a 12 week period. The convenient dosing with lesser number of total doses to complete the treatment will lead to better compliance in community setting.

Mental health effects of domestic violence against women in Delhi: A community-based study

Background:

Domestic violence (DV) against women is an all-pervasive phenomenon considered to have serious health consequences for women. This study aimed to assess the association of DV against women with their mental health status.

Materials and Methods:

This community-based, cross-sectional study was carried out among 827 ever married women from Delhi selected through cluster sampling followed by systematic random sampling. Data were collected using structured and in-depth questionnaires. Mental health status was estimated using self-reporting questionnaire 20.

Results:

The prevalence of psychological, physical, sexual, physical, or sexual violence and any form of violence was very high. A quarter of the women (25.3%) reported unhealthy mental status (>8 score) in the past 4 weeks. Women who had experienced DV showed poor mental health status and more suicidal tendencies when compared with women who had not experienced violence.

Conclusion:

DV has significant effect on women's mental health underscoring the need to develop public health interventions.

Prevalence of visual impairment and its association with vision-related quality of life among elderly persons in a resettlement colony of Delhi

Background:

The population of India is ageing. The number and percentage of elderly persons is increasing. Visual impairment is common among elderly persons and affects their vision-related quality of life. The objective of this study was to estimate the prevalence of visual impairment among elderly persons aged 60 years and above residing in a resettlement colony of Delhi and study its association with socio-demographic variables and vision-related quality of life.

Methods:

A total of 604 elderly participants were selected by simple random sampling. House-to-house visit was done, and a self-developed pre-tested semi-structured interview schedule was used to collect socio-demographic information. Visual acuity was measured using Snellen's chart, and distant direct ophthalmoscopy was done to diagnose cataract. Vision-related quality of life was assessed by Indian Vision Function Questionnaire-33 (IND-VFQ-33).

Results:

Of the 604 participants, 555 (91.9%) were available for interview. The prevalence of visual impairment was 24.5% (95% CI: 20.9% - 28.1%). Cataract was the leading cause of visual impairment (50.7%), followed by uncorrected refractive error (36.8%). Illiteracy (aOR: 3.49, 1.37-8.87), economic dependence on family members (aOR: 1.92, 1.04 – 3.54), not currently working (aOR: 1.89, 1.20-2.98) and chewing of tobacco products (aOR: 2.56, 1.48-4.42) were significantly associated with visual impairment among study participants. Vison-related quality of life was worse among those with visual impairment.

Conclusion:

Burden of visual impairment is high among elderly persons living in urban resettlement colonies. It is largely avoidable. Eye-care services should be accessible and affordable to them.

Serum inflammatory markers and nutritional status in patients with stable chronic obstructive pulmonary disease

Background

Chronic obstructive pulmonary disease (COPD) is a systemic inflammatory disease. We investigated whether serum inflammatory markers, C-reactive protein (CRP), leptin, and nutritional status (assessed by measurement of serum levels of prealbumin and anthropometry) correlated with COPD severity.

Materials and Methods

One-hundred and two COPD patients (mean age 56.94 ± 10.95 years) were recruited and classified into severity categories based on the GOLD guidelines. Serum concentrations of CRP, prealbumin, and leptin were measured. Anthropometry included body mass index (BMI), mid-upper arm circumference (MUAC), and sum of four skinfold thicknesses (triceps, biceps, suprailiac, and subscapular).

Results

Twenty-one patients had moderate, 44 had severe, and 37 had very severe COPD. Levels of CRP (mg/dl) (mean ± standard error [SE]) in moderate, severe, and very severe COPD were 0.60 ± 0.096, 2.16 ± 0.39, and 4.15 ± 0.463, respectively. Levels of prealbumin (mg/dl) (mean ± SE) in moderate, severe, and very severe COPD were 15.7 3 ± 0.92, 10.95 ± 0.85, and 11.15 ± 0.79 mg/dl, respectively. Levels of leptin (ng/ml) (mean ± SE) in moderate, severe, and very severe COPD were 13.81 ± 3.88, 8.45 ± 2.25, and 4.40 ± 1.06, respectively. BMI values in the three groups were 23.44 ± 1.16 kg/m², 20.33 ± 0.62 kg/m², and 18.86 ± 0.52 kg/m², respectively. Sum of four skinfold thickness and MUAC was significantly reduced in very severe group as compared to moderate and severe group. Very severe COPD patients had a significantly lower leptin, BMI, and 6-min walk test. Serum CRP was significantly higher in very severe COPD.

Conclusion

Patients with increasing severity of COPD had a significantly greater serum inflammatory marker level and poorer nutritional status.

Awareness and utilization of social welfare schemes by elderly persons residing in an urban resettlement colony of Delhi

Background:

Demographic transition increased the proportion of elderly in India. Elderly persons experience increased economic dependency for their day-to-day existence. The Government of India provides monetary benefit through social welfare schemes. Health outcomes of the elderly improve when they are economically independent. We aimed to assess the awareness and utilization of social welfare schemes among elderly persons in an urban resettlement colony of Delhi.

Materials and Methods:

This was a community-based cross-sectional study conducted from February to May 2018. Two specially recruited interviewers administered the self-developed semi-structured interview schedule. It consisted of sociodemographic data, awareness, and utilization of various schemes.

Results:

A total of 931 [416 (37.4%) males and 515 (55.3%) females] participants completed the interview. Of the total, 809 (86.9%) participants were aware of at least one social welfare scheme. Participants utilizing any of the social welfare schemes were 393 (42.2%). Females utilized the social welfare schemes almost twice as compared to males (AOR = 1.7, 95% CI: 1.1–2.6). Participants aged 75 years and above had four times higher utilization of social welfare schemes compared to 60–64 years age group (AOR = 3.9, 95% CI: 2.4–6.4).

Conclusion:

Although the awareness of social welfare schemes among elderly persons was good, their utilization has scope for significant improvement. Focus is needed on elderly males and among the younger elderly persons.

Trends of loss of peripheral muscle thickness on ultrasonography and its relationship with outcomes among patients with sepsis

Background and aims

Data regarding trends of muscle loss on ultrasonography (USG) and its relationship with various outcomes among critically ill patients is limited. This study aimed to describe the trends of loss of muscle thickness of the arm and thigh (assessed using USG) and to determine the relationship between loss of muscle thickness and in-hospital and post-discharge outcomes.

Methods

Muscle thickness of 70 patients with sepsis was measured at the level of the mid-arm and mid-thigh using bedside USG on days 1, 3, 5, 7, 10 and 14 and then weekly till discharge or death. Patients were followed up for 90 days after discharge.

Results

The muscle thickness (mean ± SD) at the level of the mid-arm and mid-thigh on day 1 was 23.13 ± 4.83 mm and 31.21 ± 8.56 mm, respectively. The percentage muscle thickness [median (min, max)] decline at the mid-arm and mid-thigh was 7.61 (- 1.51, 32.05)% and 10.62 (- 1.48, 32.06)%, respectively on day 7 as compared to baseline (p < 0.001). The decline in muscle thickness at the mid-arm and mid-thigh were higher among non-survivors compared to survivors at all time points. Also, the decline in muscle thickness was significantly higher among patients with worse outcome at day 90. Patients with ICU-acquired weakness also had significantly higher decline in muscle thickness (p < 0.05). Early decline (from day 1 to day 3) in muscle thickness was associated with in-hospital mortality. The probability of death by day 14 was higher for patients who had early decline (from day 1 to day 3) in muscle thickness of ≥ 6.59% and ≥ 5.20% at the mid-arm [HR 7.3 (95% CI 1.5, 34.2)] and the mid-thigh [HR 8.1 (95% CI 1.7, 37.9)], respectively. Decline in thickness from day 1 to day 3 was a good predictor of in-hospital mortality with area under the curve (AUC) of 0.81 and 0.86 for arm and thigh muscles, respectively.

Conclusions

Critically ill patients with sepsis exhibit a gradual decline in muscle thickness of both the arm and thigh. Decline in muscle thickness was associated with in-hospital mortality. USG has a potential to identify patients at risk of worse in-hospital and post-discharge outcomes.

Peptide-based therapeutics: quality specifications, regulatory considerations, and prospects

Exquisite selectivity, remarkable efficacy, and minimal toxicity are key attributes inherently assigned to peptides, resulting in increased research interest from the pharmaceutical industry in peptide-based therapeutics (PbTs). Pharmacopoeias develop authoritative standards for PbT by providing standard specifications and test methods. Nevertheless, a lack of harmonization in test procedures adopted for PbT in the latest editions of Pharmacopoeias has been observed. Adoption of a harmonized monograph could increase further the interest of the global pharmaceutical industry in PbTs. Here, we provide an overview of pharmacopoeial methodologies and specifications commonly observed in PbT monographs and highlight the main differences among the pharmacopoeias in terms of the active pharmaceutical ingredients that they focus on. We also address the prospects for PbTs to mature as a new therapeutic niche.

Etiology of short stature in Indian children and an assessment of the growth hormone-insulin-like growth factor axis in children with idiopathic short stature

Background Our objectives were to evaluate the etiology of short stature, assess the prevalence of idiopathic short stature (ISS) and assess the growth hormone (GH)-insulin-like growth factor (IGF) axis in children with ISS. Methods A stepwise diagnostic evaluation was done in 394 children aged 4-16 years with short stature. Children with no definitive etiology were labeled as ISS. In these children, baseline IGF-1, IGF binding protein-3 (IGFBP-3) and stimulated IGF-1 after administration of GH for 4 days were measured. Results Hypothyroidism (in 18.1%) and ISS (in 15.5%) were the commonest causes of short stature. In children with ISS (n=61), the mean baseline and stimulated IGF-1 standard deviation scores (SDSs) were -1.2±1.0 and -0.3±1.4, respectively, with levels below -2 SDS in 13 (21%) and six (10%) children, respectively. In 33 (54%) of the ISS patients, response to GH was suboptimal (increment in the IGF-1 level <40%). There was no difference in the mean peak GH, IGFBP-3 and baseline and stimulated IGF-1 levels between children with familial and non-familial ISS. A significant positive correlation of height SDS with baseline IGF-1 SDS (r=0.28, p=0.026), stimulated IGF-1 SDS (r=0.32, p=0.010) and ΔIGF-1 SDS (r=0.26, p=0.036) was observed in children with ISS. Conclusions Hypothyroidism and ISS were the commonest etiologies for short stature. The baseline IGF-1 was below -2 SDS in 21% and the increment after GH stimulation was suboptimal in 54% of children, indicating that a substantial proportion of children with ISS had an impaired GH-IGF axis.
