Assessing the role of mid upper arm circumference in identification of low birthweight and wasting in early infancy in India.

AIM: We conducted this study to examine the mid upper-arm circumference (MUAC) of full-term infants from birth to 6 months; construct gender-specific MUAC graphs; and assess the role of MUAC as a surrogate marker for low birthweight and wasting in infants younger than 6 months. METHODS: This is a prospective longitudinal study of 268 (133 female and 135 male) new-borns in a tertiary care centre in Navi Mumbai, India. We measured weight, length, head circumference and MUAC. We drew the MUAC curves for the first 6 months using the mean MUAC and standard deviation (SD) values and assessed the diagnostic test properties of MUAC at birth as a marker of low birthweight. RESULTS: The mean (SD) birthweight of the male and female new-borns was 2756.2 g (368.1) and 2803.8 g (326.2), respectively (P = 0.25). The mean (SD) MUAC at birth was 8.7 (0.3) cm in males and 8.8 (0.2) cm in females, respectively (P = 0.14). The plotted mean MUAC curve in infants who were classified with wasting was between the -1SD and -2SD in both genders. The sensitivity and NPV for detecting low birthweight were 100% at cut-off of 8.6 cm in females and 8.7 cm in males, respectively (area under the curve: 0.92 (females) and 0.96 (males)). CONCLUSION: MUAC may be a good proxy for low birthweight at birth and the curves from our study show that it may also help in the diagnosis of wasting in infants below 6 months of age in the community, particularly in resource-constrained settings.

Validation of a Clinical Risk-scoring Algorithm for Scrub Typhus Severity in South India.

BACKGROUND: A clinical risk-scoring algorithm (CRSA) to forecast the scrub typhus severity was developed from two general hospitals in Thailand where patients were classified into three groups-nonsevere, severe, and fatal. In this study, an attempt was made to validate the risk-scoring algorithm for prognostication of scrub typhus severity in India. MATERIALS AND METHODS: This prospective study was conducted at a hospital in South India between November 2017 and March 2019. Patients of scrub typhus were categorized into nonsevere, severe, and fatal according to the CRSA. The patients were also grouped into severe and nonsevere according to the definition of severe scrub typhus which was used as a gold standard. The obtained CRSA score was validated against the classification based on the definition of severe scrub typhus. Receiver operating characteristics (ROC) curve for the scores was plotted and the Youden's index for optimal cutoff was used. RESULTS: A total of 198 confirmed cases of scrub typhus were included in the study. According to the ROC curve, at a severity score ≥7, an optimal combination of sensitivity of 75.9% and specificity of 77.5% was achieved. It correctly predicted 76.77% (152 of 198) of patients as severe, with an underestimation of 10.61% (21 patients) and an overestimation of 12.63% (25 patients). CONCLUSION: In the present study setting, a cutoff of ≥7 for severity prediction provides an optimum combination of sensitivity and specificity. These findings need to be validated in further studies. HOW TO CITE THIS ARTICLE: Gulati S, Chunduru K, Madiyal M, Setia MS, Saravu K.

The effects of health education intervention on promoting knowledge, beliefs and preventive behaviors on brucellosis among rural population in Nagpur district of Maharashtra state, India.

Introduction: Brucellosis is one of the most common zoonosis diseases in developing and undeveloped countries, with adverse socio-economic status and animal and human health. The essential element for effective prevention and control of brucellosis is to improve the community's Knowledge, Attitude, and Practice (KAP) through Health Education Intervention (HEI). Aim: To assess health education intervention's effect on promoting knowledge, beliefs, and preventive behaviors on brucellosis among rural populations in Nagpur district, Maharashtra, India. Methods and Materials: 382 subjects over 18 years with a history of animal contact or consuming animal products were randomly selected. Data were collected through questionnaires and checklists. The pre-test was implemented and followed by HEI. The post-test was conducted after 45 to 60 days. For the attitude five-point Likert scale and knowledge and practice, a two-point assessment scale [yes, no] was applied. SPSS was used to analyze paired t-test, and P < 0.05 was considered significant. Result: Of 382 subjects, 300 (78.5%) were male, and the mean age of 42.15 ± 13.72. Before HEI, 18 (5%) subjects heard about brucellosis. After HEI, reduction in the risk behaviors practices like raw milk consumption (P < 0.0001), assisted animal delivery without gown (P = 0.002), throwing animal birth products in the dustbin (P < 0.0001) were statistically significant. After implementing HEI, subjects were more aware of animal and human brucellosis signs/symptoms (P < 0.0001). Awareness of disease transmission route (P < 0.0001) and up-gradation in knowledge (P < 0.0001) were statistically significant among subjects after HEI. Conclusions: HEI substantially affects KAP and changes community behaviors to prevent brucellosis transmission. The authors recommend implementing HEI in the community to prevent brucellosis.

Quality of Life of Patients with Wilson's Disease and Their Families.

Objectives: Wilson's disease (WD) is a chronic disease caused by altered copper metabolism requiring lifelong therapy. Its long-term and debilitating nature has the potential to affect the quality of life (Qol) of patients as well as their families. Our study aims to assess this impact of the disease on patients and their families. Methods: We conducted a prospective, observational study over 2 years on 73 patients and 73 age-matched controls with 33 children and 40 adults in each group. The Qol of cases and controls was assessed using the PedsQL Generic Core Scales and World Health Organisation Quality of Life BREF (WHOQOL-BREF) for children and adults, respectively. Families of child and adult patients were interviewed using PedsQL Family Impact Module and Family Attitude Scale (FAS), respectively. The data were statistically analyzed. Results: Mean age of the cases was 22.04 ± 11.8 years. Qol scores for both adults and children were worse in cases with neuropsychiatric disease than in those with hepatic disease. For children, the mean scores of overall psychological functioning were lower in cases compared with controls (P = 0.0001). Qol of parents of the patients was significantly lower than those of parents of the controls as was the family functioning (P = 0.0001 and P = 0.016). Family Attitude Scale scores for adults did not differ significantly between cases and controls. Conclusion: The Qol of patients with neuro-WD is worse than that of hepatic disease. The disease impacts the psychological functioning of the children and the Qol of their families, which improves with the duration of the disease. What is known: WD is a long-term, debilitating disease. Patients have to take lifelong treatment with frequent medical visits and often multiple hospitalizations. What is new: WD affects the Qol of not only the patients but also their families. Qol of patients with neuro-WD is worse than that of patients with hepatic disease.

Is there a role for rifampicin, ofloxacin and minocycline (ROM) therapy in the treatment of leprosy? Systematic review and meta-analysis.

BACKGROUND: A combination of rifampicin, ofloxacin and minocycline (ROM) is one of the newer recommendations for treatment of leprosy. We performed a systematic review and a meta-analysis of studies that had evaluated the efficacy of ROM therapy in treatment of paucibacillary and multibacillary leprosy patients. METHODS: Studies were identified by searching the PubMed, Embase, LILACS and Cochrane databases. Data were abstracted from all relevant studies, and fixed effects models were used to calculate the summary estimate of effect in paucibacillary and multibacillary leprosy patients. RESULTS: Six studies comparing ROM therapy to multidrug therapy and eight studies that evaluated the effect of ROM therapy alone (no comparison group) were included in the review and meta-analysis. The combined estimate for single dose ROM vs. multidrug therapy in paucibacillary leprosy patients suggested that ROM was less effective than multidrug therapy in these patients [relative risk: 0.91, 95% confidence intervals (CI): 0.86-0.97]. However, the combined estimate for multiple doses of ROM vs. multidrug therapy in multibacillary leprosy patients suggested that ROM was as effective as multidrug therapy in reducing bacillary indices in these patients (proportion change: -4%, 95% CI -31% to 23%). No major side effects were reported in either the ROM or the multidrug treatment groups. CONCLUSIONS: Single-dose ROM therapy was less effective than multidrug therapy in paucibacillary patients. However, there are insufficient data to come to a valid conclusion on the efficacy of multidose ROM therapy in multibacillary leprosy, and additional studies with ROM therapy in multibacillary leprosy are needed. Furthermore, multiple doses may be considered as another alternative even for paucibacillary patients, and randomised controlled trials of this therapy may be useful to understand its contribution in the treatment and control of leprosy.

Human brucellosis: Seroprevalence and associated exposure factors among the rural population in Nagpur, Maharashtra, India.

INTRODUCTION: Brucellosis is a recognised occupational threat among animal handler and raw animal product consumers. In India, there is a likelihood of missed diagnoses and under-reporting cases by physicians causing an extended debilitating illness. We steered research to conclude the seroprevalence and risk factors allied with Human Brucellosis (HB) among the rural population in Nagpur District, Maharashtra, India. METHODS: Closed-ended questionnaires used for a cross-sectional study to collect data for demographics and risk exposure variables. 382 subjects' serum-samples were tested by using Rose-Bengal (RBPT) and ELISA technique. An odd ratio calculated for risk factors for HB reported positive or negative. Data were analysed by using SPSS. RESULTS: The brucellosis seroprevalence in rural Nagpur was 1.83%. The mean age was 42.32 years, 78.5% were male, and 21.5% were female. Prevalence was higher among males [85.7%] than females [14.3%]. The risk for brucellosis among males (OR = 1.65, 95% CI = 0.19-13.92, P = 0.64) was more than females. Handling raw meat had more risk (OR = 3.14, 95% CI = 0.40 - 28.6, P = 0.23) than those not handling raw meat. Milking animal was protective (OR = 0.88, 95% CI = 0.80 - 0.96, P < 0.001) for brucellosis than those not milking animal. Subjects reported more likely to be a seropositive to human brucellosis those involved in assisted animal delivery (P = 0.001), drinking unpasteurised milk (P<0.001), consuming milk products made from raw milk (P<0.001) and eating raw meat (P = 0.001). CONCLUSION: Health education program is essential to generate awareness for brucellosis in the rural community to prevent animal to human disease transmission.

Clinical and demographic trends in a sexually transmitted infection clinic in Mumbai (1994-2006): an epidemiologic analysis.

BACKGROUND: People presenting to sexually transmitted infections (STIs) clinics represent an important risk group for HIV infection; prevention strategies will depend on the clinical attendance. AIMS: The demographic and clinical changes in clinic attendees in Mumbai, as well as the factors associated with HIV infection in this clinic over a 13-year period, were assessed. METHODS: STI clinic data in 3417 individuals (1994 to 2006) were analyzed: clinical presentation, types of STIs, and serology over the 13-year period. We used a logistic regression model to assess socio-demographic and clinical associations with HIV infection. RESULTS: The clinic evaluated 689 patients in 1994 and the number had dropped to 97 in 2006. In 1994, the majority of STIs seen in the clinic were bacterial (53%, 95% confidence interval [CI] 50% to 57%); however, this proportion had dropped in 2006 (28%, 95% CI: 19% to 38%). There was a proportional increase in viral STIs during the same time period. Although women attending the clinic were younger than men, they were more likely to be married. The overall seropositivity for HIV was 28%. Viral STIs were more likely to be associated with HIV than bacterial infections (odds ratio: 1.5, 95% CI: 1.2 to 1.9). CONCLUSIONS: Viral infections were the most common STIs in recent years in a tertiary care center in Mumbai. HIV prevalence was high in this population. Thus, these clinical data suggest that STI patients were and continue to be an important group for HIV prevention in the country.

Socio-geographic mobility and health status: a longitudinal analysis using the National Population Health Survey of Canada.

The paper reviews arguments that associations between small area socio-economic conditions and individual health are likely to vary according to the type of health condition considered. We comment on the importance of longitudinal research to examine how far area conditions predict later health outcomes, and also how far area variations in health may result from selective migration processes predicted by health status. Using data for 1996 and 2002, from the National Population Health Survey of Canada, linked to small area data on social and on material deprivation in the area of residence for 6950 survey respondents at the two time points, we report on analyses to address these questions. The area measures of material and social deprivation were previously developed by Pampalon and colleagues at the Institut National de Santé Publique de Québec and related to the dissemination area matching the informant's postal code. The health outcomes considered were restriction of activity due to chronic conditions and psychological distress. Our findings suggest that individuals living in materially deprived areas in 2002 were more likely to be affected by health conditions resulting in restriction of activity. Prevalence of psychological distress was higher in areas with greater social deprivation in 2002. Most of these area differences were attenuated when adjustment was made for individual socio-demographic characteristics. Measures recorded in 1996 of individual characteristics and measures of deprivation for area of residence were used to predict change in health outcomes by 2002. Several individual factors (sex, age group, income, household composition) in 1996 were predictive of later health outcomes. After controlling for these individual characteristics the only significant association between health change and area deprivation was with development of restricted activity, which was more common among people who, in 1996, had lived in areas that ranked moderately high on material deprivation. We also report some evidence for selective migration effects, though these mainly seem to operate indirectly via socio-economic characteristics that predict both health outcomes and differential migration patterns. The clearest evidence on this point is for those in with psychological distress in 1996, who were particularly likely to move to an area which was more socially or materially deprived by 2002. This supports the idea that area differences in psychological distress are partly the result of selective migration effects.
