Task-based and Magnified Mirror Therapy for Unilateral Spatial Neglect among post-stroke subjects: Study protocol for a randomized controlled trial.

BACKGROUND: Unilateral spatial neglect (USN) is a commonly occurring neurocognitive disability after a stroke. The neglect may affect the motor recovery of the upper and lower limbs and functional performances. Mirror therapy, a simple and economical approach has the potential to reduce the USN and related impairments. AIM: The primary objective of this study is to determine the effectiveness of task-based and magnified mirror therapy on the USN and on the motor recovery of the post-stroke subjects. The secondary objective is to investigate the effectiveness of the intervention on the function and disability of the subjects. METHODS: In this randomized controlled, assessor-blinded trial, 86 post-stroke subjects will be recruited from the neuro-rehabilitation laboratory of a rehabilitation institute, located in northern India. The participants,aged20 to 80 years, with 1 to 36 months of stroke onset, hemiparesis, and the USN, will be considered eligible for the study. In addition to the conventional rehabilitation, the experimental group(n = 43) will receive 40 sessions (8 weeks) of Task-based and MAGnified Mirror Therapy for Unilateral Spatial Neglect (T-MAGUSN). The control group (n = 43) will undergo a dose-matched conventional program only. The participants will be assessed at baseline, post-intervention and 4-week follow-up using primary (Line Bisection Test, Letter Cancellation Test, and Fugl-Myer Assessment) and secondary (Catherine Bergego Scale, Berg Balance Scale, Functional Ambulation Classification, Modified Rankin Scale) outcome measures. DISCUSSION: This proposed study will lead to the development of a novel rehabilitation protocol for the management of USN, aiming to enhance motor and functional recovery. The investigation will consider both the upper and lower limbs for the intervention, reducing the impact of cognitive disability in stroke.

Sensory deficits of the paretic and non-paretic upper limbs relate with the motor recovery of the poststroke subjects.

BACKGROUND: Post stroke, motor paresis has usually been considered to be a crucial factor responsible for the disability; other impairments such as somatosensory deficits may also play a role. OBJECTIVE: To determine the relation between the sensory deficits (paretic and non-paretic upper limbs) and the motor recovery of the paretic upper limb and to predict the potential of motor recovery based on the sensory deficits among stroke subjects. METHODS: The study was a cross-sectional study conducted in a rehabilitation institute. Ninety-five poststroke hemiparetic subjects having sensory impairment in any of the modalities were considered for this study. Sensory deficits were assessed on both the upper limbs (paretic and non-paretic) primarily using Erasmus MC modification of the revised version of Nottingham Sensory Assessment (Em-NSA) and Nottingham Sensory Assessment (Stereognosis) (NSA-S). The motor recovery was assessed using the Fugl-Meyer assessment (FMA). RESULTS: The measures of sensory deficits exhibited weak but significant correlation [the paretic (Em-NSA and NSA; r = .38 to .58; p < .001) and the non-paretic (Em-NSA and NSA; r = .24 to .38; p = .03 to .001)] with the motor recovery of the paretic upper limb as measured by FMA. The potential of favorable recovery of the paretic upper limb may be predicted using the cutoff scores of Em-NSA (30, 21, and 24) and NSA-S (5, 8, and 5) of the paretic side. CONCLUSION: In stroke, sensory deficits relate weakly with the recovery of the paretic upper limb and can predict recovery potential of the paretic upper limb.

Active Sensory Therapies Enhancing Upper Limb Recovery Among Poststroke Subjects: A Systematic Review.

Background: In stroke, sensory deficits may affect the motor recovery of the subjects. The evidence for the active sensory intervention to enhance motor recovery is sparsely available. Purpose: To systematically review the available evidence from the studies on active sensory therapies augmenting upper limb recovery among poststroke subjects. Methods: The following databases were searched for the desired articles: PubMed, the Cochrane Central Register of Trials (CENTRAL), DORIS, PEDro, and OTseeker. The primary search keywords were stroke, sensory, and motor. The articles published in English up to August 2021 were considered for the review. Only investigations that studied active sensory interventions to enhance motor recovery were considered for the review. The studies of robotic training, virtual reality, electrical stimulation, and acupuncture were excluded. Motor recovery and sensory recovery were considered as primary and secondary measures, respectively. Results: Out of 3528 screened studies, eight studies were found eligible for the present systematic review. Active sensory interventions in the form of sensory discrimination, mirror therapy, motor imagery, and specific somatosensory training were utilized in the selected studies. The interventions through mirror therapy and mental imaging have some promising roles in enhancing upper limb recovery. However, there is a lack of strong evidence for the effectiveness of the intervention enhancing motor improvement among the stroke subjects. Conclusion: A comprehensive active sensory protocol should be developed having components of cognitive, sensory, motor, and functional demand. There is a need to conduct good quality randomized trials to support the existing active sensory therapies.

Effect of NEuroplasticity-Principles-based SEnsory-Rehabilitation (NEPSER) on sensori-motor recovery in stroke: study protocol for a randomized controlled trial.

INTRODUCTION: Up to 2/3rd of the stroke subjects may experience impairment in any of the somatosensory modalities such as light touch, proprioception, and stereognosis. The sensory recovery is strongly associated with the level of motor recovery. Very negligible sensory-based interventions have been developed and found to be evident in enhancing the sensory deficit and associated motor recovery. The possible factor for the ineffectiveness of these sensory interventions could be lack of the neuroscientific basis in formulation of the program. Thus, the objective of the study is to determine the effectiveness of a neuralplasticity-principles-based sensory-rehabilitation protocol on motor and sensory recovery, and disability of the post-stroke hemiparetic subjects. METHODS: We propose to recruit 122 poststroke subjects in a randomized controlled, assessor blinded trial to be conducted in a rehabilitation-institute. The key eligibility criteria is age between 20 to 80 years, hemiparesis (right or left), ischemic or hemorrhagic stroke, 1 to 12 months poststroke, and impairment in any of the sensory modalities. The participants in the experimental group will receive NEuroplasticity-Principles-based SEnsory-Rehabilitation (NEPSER) protocol comprising active, repetitive, and meaningful training of the specific sensory modalities utilizing visuo-perceptual, cognitive, motor, and functional tasks will be imparted for 8 weeks, 5 sessions / week, each of 2 h. The control subjects will undergo only standard rehabilitation based on neurophysiological, biomechanical, and rehabilitative approaches. All the participants will be assessed for motor (Fugl-Meyer assessment, upper extremity section) and sensory recovery [Nottingham Sensory assessment (Erasmus MC modification of the revised version)] at baseline, 8-week, and 12-week follow-up. The Semmes weinstein monofilament, two-point discrimination test and modified rankin scale (disability) will be applied as secondary measures. A repeated-measures 2-way ANOVA will be used to estimate difference for the post intervention and follow-up scores between the groups. PERSPECTIVE: The proposed study will lead to development of a novel rehabilitation protocol that will not only enhance the sensory recovery but also the motor and functional recovery. This may reduce the impact of stroke disability and enhance the quality of life. TRIAL REGISTRATION: The trial has been registered under Clinical Trial Registry of India (CTRI) as CTRI/2019/09/021442 on 30th September 2019.

Study on prevalence and sociocultural aspects of tobacco use in India.

AIM: The present study focuses on the prevalence of tobacco use and aims to determine various sociocultural aspects of tobacco use in Indian population. MATERIALS AND METHODS: The study sample comprised 384 participants. There were three study groups, and in each study group, there were 128 participants. Group A was tobacco users without oral precancer, Group B was tobacco users with oral precancer, and Group C was healthy individuals with no history of tobacco or areca nut use and oral precancer. Both male and female adults in the age group of 18 years and above visiting the Outpatient Department of Oral and Maxillofacial Surgery at King George's Medical University were recruited for the study. The study participants were explained in detail about the study, and informed consent was obtained through them. Data have been collected using a standard structured predesigned questionnaire. The questionnaire consisted of the details of the demographic profile of the study participants, details of tobacco use, and the major social and cultural reasons which motivated them to consume tobacco. Data were extracted from the case sheet, and the data were entered into a worksheet for the purpose of analysis. The analysis was performed using the commercially available Statistical Package SPSS. CONCLUSION: The rate of tobacco prevalence is very high among the Indian population, and a number of social and cultural factors are responsible for its use. To curb this problem, more studies could be done to find the causes responsible for its use.

Post-stroke Visual Gait Measure for Developing Countries: A Reliability and Validity Study.

BACKGROUND: Visual gait assessment is a cost-effective clinical method to assess post-stroke gait deviations. The Rivermead Visual Gait Assessment (RVGA) is a one such measure that assesses the kinematic aspect of the gait deviations in stroke. However, the available information on psycho-clinocometric properties of the measure is not adequate. OBJECTIVE: To establish reliability and validity of RVGA using walking-videos of the post-stroke subjects. METHODS: Design: Observational study. SETTING: A rehabilitation institute Participants: A convenience sample of 40 chronic stroke patients. OUTCOME MEASURES: RVGA, Fugl-Meyer assessment (lower extremity), 10-m walk test, Time up and go test, and Berg balance scale (BBS). PROCEDURE: Walking was video-taped from the anterior aspect, posterior aspect, affected side, and less-affected side. After coding the tapes, a research staff member provided them to four different raters in a random order. Each rater scored the coded video on the RVGA data collection sheet twice: one at the baseline and another after 1 month to eliminate any recollection of the initial assessment. RESULTS: The findings exhibit that there was good-to-excellent agreement between the scores of the raters and also between the assessments (correlation coefficient = 0.94 to 0.95; P < 0.001). The measure also exhibits acceptable validity when correlated with scores of BBS (r = 0.4; P < 0.001). CONCLUSION: Video-based RVGA is a reliable and valid tool to assess gait-related impairment in post-stroke hemiparesis. This cost-effective measure may be incorporated in the clinical and research practice to discern and quantify complex phenomenon of the gait deviation. RVGA may be considered as a useful tool, especially in developing countries where expensive gait analyzer is usually not available.

Sample attrition rate of a community study: An analysis of Lucknow urban and rural elderly follow-up over a period of 9 years.

BACKGROUND: Longitudinal/follow-up studies of older adults are a tough task as sample attrition rates due to mortality and other factors may be high in this particular group. However, such studies are very much needed to assess the outcome of health status as well as explore preventive, protective, interventional aspects, as well as risk factors. Given this, a follow-up study was planned and carried out. AIM: To discuss the rate of sample loss as well as the reasons over 9 years. METHODS: An Indian Council of Medical Research (ICMR) supported follow-up study of urban and rural elderly was done during June, 2016-May, 2017; these subjects were studied in 2007-09 through two independent ICMR supported studies. Similar methodology and assessment tools were applied in these studies. During follow-up a semi structured proforma was developed to get the information of study cohort, obtained data was analyzed and presented applying percentage statistics. RESULTS: The sample attrition rate was reported to be comparatively high in urban 52.1% (n= 633) cohort than their rural counterparts 36.3% (n= 457). CONCLUSION: Over a period of 9 years chances of cohort loss due to mortality is about 32%-35%.

An epidemiological survey in hospital setup in Lucknow district: A cross-sectional study.

INTRODUCTION: Oral cancer is the sixth most common form of cancer reported globally which includes lip, tongue, mouth, and throat. Developing countries face several challenges to identify and remove potential risk factors. Chewing tobacco/pan masala is considered to be the most potential risk factor for oral precancerous lesions and oral cancer. OBJECTIVE: To study the clinical-epidemiological profile of oral cancer cases and potential risk factor associated with it. MATERIALS AND METHODS: This is cross-sectional study which includes all major tertiary hospital in Lucknow district. Five hundred and eight cases of oral cancer reported in all major tertiary hospitals in Lucknow district during 2013-2016. STUDY VARIABLE: Clinicoepidemiological characteristics of oral cancer cases. STATISTICAL ANALYSIS: percentages, proportions. RESULTS: Out of 508 cases, majority of the subjects included in the study belonged to 18-75 years age group. Reported cases of oral cancer in males were higher as compared to females. Most of the subjects belonged to lower middle and upper lower socioeconomic group. It was found that 199 (39.2%) subjects consumed smokeless tobacco. Buccal mucosa was the common site of oral cancer being present in 50.4% of the subjects. Histopathologically, 256 cases of buccal mucosa, 17 cases of lip, 33 cases of alveolar region, 16 cases of mandible region, 156 cases of tongue region, 7 cases of gingival buccal sulcus region, and 23 cases of palate were diagnosed as oral squamous cell carcinoma. CONCLUSION: In the present study, the most affected site was buccal mucosa (50.4%), tongue (30.7%), and other diagnosis was <10%.

Survey of Neurological Disorders in Children Aged 9-15 Years in Northern India.

The prevalence of neurological disorders in resource-poor settings, although likely to be high, is largely unexplored. The prevalence and risk factors for neurological disorders, including epilepsy and intellectual, motor, vision, and hearing deficits, in children aged 9 to 15 years in the community were investigated. A new instrument was developed, validated, and used in a 2-stage community survey for neurological disorders in Lucknow, India. Screen-positives and random proportion of screen-negatives were validated using predefined criteria. Prevalence of different neurological disorders was calculated by weighted proportions. Of 6431 children screened, 221 were positive. A total of 214 screen-positives and 251 screen-negatives were validated. Prevalence of neurological disorders was 31.3 per 1000 children of this age group (weighted 95% confidence interval = 16.5, 46.4). The final model for risk factors included age, mud house, delayed cry at birth, and previous head injury. The prevalence of neurological disorders is high in this region. Predictors of neurological disorders are largely modifiable.

Prevalence of psychiatric morbidity among urban elderlies: Lucknow elderly study.

BACKGROUND: Paucity of systematic studies in elderly mental health in an aging population is an urgent need, which is required to address services and planning issues for health. AIM: The present study aims to investigate the distribution of physical, neuropsychiatric, and cognitive disorders of a community sample of elderlies with certain socioeconomic data. MATERIALS AND METHODS: A door-to-door household survey was conducted to identify houses with elderlies (≥55 years) in two urban localities of Lucknow. Mini mental state examination (MMSE), Survey Psychiatric Assessment Schedule (SPAS)/Mood Disorder Questionnaire (MDQ) and physical and neurological examination were used for screening all consenting elderlies. MMSE positive participants were assessed on Cambridge Mental Disorders of the Elderly Examination-Revised for diagnosis of cognitive disorders; SPAS/MDQ positives were assessed on Schedule for Clinical Assessment in Neuropsychiatry based clinical interview for diagnosis of neuropsychiatric disorders other than cognitive disorders (using ICD-10 criteria). Routine and indicated laboratory/radiological investigations on all and on MMSE/SPAS (organic section) positive/physically ill participants respectively were done to confirm organic and/or physical illness. Only percentages were calculated to find the distribution of morbidity. RESULTS: The sample had proportionate age structure as that of the surveyed population and had balanced gender representation in each age deciles. Prevalence of neuropsychiatric disorders (with/without comorbidities) was 11.8% in the elderlies (60 years and above) highest being in the 60-69 years age group. Being women and of lower socioeconomic status was more commonly associated with a neuropsychiatric diagnosis. 7.6% of the elderlies had cognitive impairment. Overall findings suggest a prevalence rate of 17.34% of total psychiatric morbidity among elderlies. A significant number had comorbid physical illness diagnoses. CONCLUSION: More than half the elderlies had some diagnosable physical or mental ailment. The study familiarizes us to the significant amount of physical and psychiatric comorbidity in the particular age group. About one-fifth was found to suffer from psychiatric morbidity, which any health services for the elderly should be oriented towards.

A randomized, double-blind, placebo-controlled trial of ormeloxifene in breast pain and nodularity.

BACKGROUND: Breast pain and non-discrete breast nodularity are common in women. METHODS: We did a randomized, double-blind, placebocontrolled trial of oral ormeloxifene 30 mg, a selective oestrogen receptor modulator (SERM) or placebo twice a week for 3 months in 20-50-year-old women with breast pain with or without lumpiness. Women with a discrete benign lump or cancer were excluded from the study. Serial assessments of pain on a visual analogue scale and nodularity grade on a 5-point ordinal Lucknow-Cardiff scale were done. A total of 151 patients were randomly allocated to two interventions using a block size of 4. RESULTS: Of the 151 patients, 121 (active 57, placebo 64) were available for efficacy analysis. The mean pain level showed a systematic downward trend over five visits (F=105.23, p<0.0001) that significantly reduced in the active group compared to that in the placebo group (F=18.66, p<0.0001). The patterns of variation in pain over time for the individual groups differ from the overall mean pattern for the two groups and thus from one another (F=44.43, p<0.0001). Cumulative frequencies of breast nodularity grades during successive visits showed significant improvement (p=0.001) compared to placebo at the end of the third month. The effect of the active drug persisted till the completion (6 months) of treatment (p<0.001). At the last visit, 93.3% of women in the active group had grade 2 or lower nodularity as compared to 71.1% in the placebo group. Oligomenorrhoea alone was reported by 12 patients. CONCLUSION: Ormeloxifene showed significant efficacy for treating breast pain and nodularity.

Prevalence of psychiatric morbidity amongst the community dwelling rural older adults in northern India.

BACKGROUND & OBJECTIVES: The population of elderly is growing globally and so are the physical illnesses and psychiatric morbidity. This study was planned to assess the prevalence and patterns of psychiatric morbidity amongst rural older adults in Lucknow, north India. METHODS: A survey was conducted in subjects aged 60 yr and above to identify the cases of psychiatric morbidity in rural population from randomly selected two revenue blocks of Lucknow district, Uttar Pradesh, India. All subjects were screened through Hindi Mental Status Examination (HMSE) and Survey Psychiatric Assessment Schedule (SPAS) to identify for the suspected cases of cognitive and the psychiatric disorders, respectively. The subjects screened positive on HMSE and SPAS were assessed in detail on Cambridge Mental Disorder of the Elderly Examination-Revised (CAMDEX-R) and Schedule for Clinical Assessment in Neuropsychiatry (SCAN), to diagnose cognitive disorders and psychiatric disorders (other than the cognitive), respectively on the basis of International Classification of Diseases-10 (ICD-10) diagnostic guidelines. RESULTS: The overall prevalence of psychiatric morbidity in rural older adults was found to be 23.7 per cent (95% CI=21.89-25.53). Mood (affective) disorders were the commonest (7.6%, 95% CI=6.51-8.80), followed by mild cognitive impairment (4.6%, 95% CI=3.72-5.53), mental and behavioural disorders due to substance use (4.0%, 95% CI=3.17-4.87) and dementia (2.8%) [Alzheimer's disease (2.4%, 95% CI=1.81-3.16) and vascular (0.4%, 95% CI=0.16-0.73)]. INTERPRETATION & CONCLUSIONS: Overall prevalence of psychiatric morbidity amongst rural elderly in this study was found to be less in comparison to those reported in earlier studies from India. However, prevalence pattern of different disorders was found to be similar. Therefore, it appears that a stringent methodology, refined case criteria for diagnosis and assessment by trained professionals restrict false diagnosis.

Odds ratio of risk factors for oral submucous fibrosis in a case control model.

Our aim was to calculate the odds ratio (OR) of various epidemiological, social, behavioural, and dietary risk factors for oral submucous fibrosis in a population-based case control study. We did this in rural and urban Lucknow by organising oral health camps in the community, where a total of 3136 subjects were enrolled. Panmasala, a dry commercial preparation containing areca nut, slaked lime, catechu, and condiments, with or without tobacco, was the most important aetiological factor for the disease. The 95% confidence interval (CI) of the OR for tobaccoless panmasala ranged from 4.77 to 6.88 and for tobacco panmasala from 4.55 to 9.71. OR using multivariate analysis was 14.09 for tobaccoless panmasala and 5.39 for tobacco panmasala. Patients who use panmasala are at high risk of developing oral submucous fibrosis.

Association of TNF-α promoter gene G-308A polymorphism with metabolic syndrome, insulin resistance, serum TNF-α and leptin levels in Indian adult women.

BACKGROUND: Tumour necrosis factor alpha is a multifunctional proinflammatory cytokine involved in the pathogenesis of metabolic syndrome, insulin resistance, and obesity. Aim of this study is to investigate in a North Indian female population the impact of the G-308A TNF-α variant on various components of the metabolic syndrome, Insulin Resistance, serum TNF-α and Leptin levels. METHODS: The G-308A TNF-α polymorphism has been studied in 269 females with metabolic syndrome (NCEP ATP III criteria) (age 31.91±6.05) and 272 healthy females without metabolic syndrome (age 30.96±7.01). The G-308A variant was detected by PCR amplification and Nco-1 digestion. RESULTS: Homozygous mutant genotype (AA) (p=<0.001: OR=3.24: 95% CI=2.15-4.89) and mutant allele (A) (p=<0.001: OR=3.04: 95% CI=2.08-4.43) of TNF-α was significantly less frequently observed in the control population as compared to study group. Furthermore, on dividing the subjects into two groups according to the absence (TNF-1 allele) or presence of the mutant A (TNF-2) allele, significant results were obtained in most of the metabolic risk factors. CONCLUSIONS: Our results suggest that the G-308A polymorphism of the TNF-α gene may be independently associated with hypertension, leptin level and hypercholesterolemia leading to metabolic syndrome independent of Insulin resistance and hyperglycemia.

Profile of CD4 counts and symptoms in HIV positive patients on and not on antiretroviral therapy.

This communication pertains to a study on analysis of the profile of CD4 counts and symptoms in HIV infected adult subjects on and not on antiretroviral therapy. Clinical symptoms in HIV infected patients attending a tertiary care hospital in north India were recorded by direct questioning. Differences in distribution of categorical variables were analyzed using chi-square test. A p-value < 0.05 was considered statistically significant. 317 enrolled HIV positive patients, 271/317 (85.5%) patients were symptomatic. The common symptoms were weakness (65.6%), bodyache and joint pain (63.4%), lethargy and fatigue (62.5%), prolonged fever (53.3%), weight loss (47.6%), cough (44.5%), loss of appetite (44.2%) and chronic diarrhoea (40.1%). Most symptoms were found significantly less frequently in patients on antiretroviral therapy (ART). High CD4+ T-cell counts were negatively associated with symptoms. The overall proportion of symptomatic patients was significantly higher than the number with an etiologically documented opportunistic infections (32.5%). Pulmonary tuberculosis (30.9%) was the most frequently documented opportunistic infection. Antiretroviral therapy appears to be beneficial in reducing symptoms in HIV positive patients. Affordable high quality laboratory diagnostic facilities for the diagnosis of opportunistic infections under the public health program will help to obtain an accurate picture of the range of opportunistic infections in HIV patients in India.

Cytokine gene polymorphism in idiopathic nephrotic syndrome children.

The pathogenesis of idiopathic nephrotic syndrome is not completely understood. We postulate that cytokine gene polymorphisms may influence susceptibility or clinical course in Idiopathic Nephrotic Syndrome. Polymorphisms of IL-4, IL-6, and TNF-α cytokines were investigated in 150 children with Idiopathic Nephrotic Syndrome and 569 healthy controls by using polymerase chain reaction and restriction fragment length polymorphism. On comparing patient with controls strong association were found for IL-6, TNF-α and IL-4 at allelic level (IL-6-G174C (G vs. C): P = <0.001; OR = 6.33, TNF-α-G308A (G vs. A): P = <0.001; OR = 1.99, IL-4-C590T (C vs. T): P = 0.048; OR = 1.38). Further when SR group was compared with SS group significant association was found at genotypic level in all the studied genetic polymorphisms. Studied cytokine gene polymorphisms may influence susceptibility to idiopathic nephrotic syndrome and might affect steroid response in INS patients.

Relationship of severity of depression, anxiety and stress with severity of fibromyalgia.

OBJECTIVES: Negative affects like depression, anxiety and stress are frequently observed in patients with fibromyalgia (FMS). Understanding the association between FMS and negative affects is likely to help in deciding the choice of treatment. The aim of this study was to determine the correlation between the severity of FMS with the severity of depression, anxiety and stress. METHODS: Sixty patients with fibromyalgia and 60 healthy controls were included in the study. Fibromyalgia Impact Questionnaire Revised (FIQR), and Depression, Anxiety and Stress Scale (DASS21) were administered to both the groups. The mean age of study population was 40.4±9.9 and 36±8.7 for FMS and control groups respectively. Most of the patients were females (93.3%). RESULTS: In subjects without FMS, depression was seen in 5% and was significantly associated with all three components of FIQR (p<0.01), namely pain, symptoms and functional impairment. However, patients with FMS suffered more from all three components assessed in FIQR than those without FMS. In patients with FMS the severity of depression, anxiety and stress were found significantly associated with the severity of all three components of FIQR, namely pain, function and symptoms (p<0.01). CONCLUSIONS: Results suggest that FMS is associated with depression, anxiety and stress and in FMS magnitude of negative affects is significantly correlated with FIQR. However, depression alone in absence of FMS can also give rise to all three components of FIQR.

A case-control study of tobacco smoking and tuberculosis in India.

OBJECTIVES: To evaluate the role of smoking as a risk factor for the development of pulmonary tuberculosis. MATERIALS AND METHODS: A total of 111 sputum smear-positive patients of pulmonary tuberculosis and 333 controls matched for age and sex were interviewed according to a predesigned questionnaire. RESULTS: The adjusted odd ratio of the association between tobacco smoking and pulmonary tuberculosis was 3.8 (95% confidence interval, 2.0 to 7.0; P value, < 0001). A positive relationship between pack years, body mass index and socioeconomic class was also observed. CONCLUSION: There is a positive association between tobacco smoking and pulmonary tuberculosis.

Lipid peroxidation and antioxidants in different stages of cervical cancer: Prognostic significance.

BACKGROUND: Free radical Injury is associated with cancer, but how the extent of oxidative stress correlates with the FIGO (International Federation of Gynecology and Obstetrics) stage in Carcinoma Cervix (Ca Cx), and its significance as a prognostic marker, is not clear and needs an in-depth study. AIM: To correlate the blood levels of Lipid Peroxidation (LPO), Reduced Glutathione (GSH), Superoxide Dismutase (SOD), and Vitamin A and E levels with the clinical stage in Ca Cx. SETTINGS AND DESIGN: This is a Prospective Case Control Study. MATERIALS AND METHODS: LPO, SOD, reduced GSH were estimated by Bio Chemical Assays and Vitamins by High Performance Liquid Chromatography (HPLC). STATISTICAL ANALYSIS: The cases and controls were compared using One Way ANOVA and different stages over different time periods were individually compared by Repeated Measure Analysis of Variance. RESULTS: The results indicated a statistically significant increase of LPO vis-a-vis the FIGO stage of Ca Cx and control, while the antioxidant status as depicted by GSH and SOD decreased. Vitamin A and E levels were significantly lower in cancer cases as compared to the control. CONCLUSION: Increased LPO and reduced antioxidant levels may be taken as associated predictive markers, thus suggesting that Ca Cx cases should get nutritive supplements to contain the blood LPO level and maintain a positive balance of antioxidants for a better outcome in terms of delayed recurrence and better Quality of Life (QOL).

Serum homocysteine in Indian adolescents.

OBJECTIVE: To assess serum homocysteine levels and its association with conventional risk factors for cardiovascular disease (CVD) in Indian adolescents. METHODS: This was a cross-sectional study conducted in tertiary care hospital in northern India in apparently healthy adolescents aged 10-19 yr. A pre-designed questionnaire was used to assess conventional risk factors. Serum homocysteine levels of > or = 12 micromol/L, serum triglycerides > or = 150 mg% and serum cholesterol > or = 200 mg% were taken as hyperhomocysteinemia, hypertriglyceridemia and hypercholesterolemia, respectively. Serum high-density lipoprotein (HDL) > or = 40 mg% was considered protective for CVD. RESULTS: In 103 subjects, 36.87 % females, mean serum homocysteine level was 11.649 +/-0.416 micromol/L. Hyperhomocysteinemia was present in 46 (44.6%, 95% CI: 34.965-54.75) subjects. Dietary deficiency of vitamin B12 and folic acid, body mass index (BMI) > 84(th) percentile and altered lipid profile were associated with hyperhomocysteinemia on univariate analysis. After multivariate adjustment for BMI and vegetarian diet, low serum HDL (OR: 23.81, 95% CI: 2.86-200; p = 0.003) and serum hypertriglyceridemia (OR: 4.17, 95% CI: 1.51-13.51; p = 0.022) had independent association with hyperhomocysteinemia. CONCLUSION: Since we have also found an association between hyperhomocysteinemia and low serum HDL levels and hypertriglyceridemia, which are conventional risk factors for CVD, interventional strategies are urgently needed among adolescents for prevention of CVD.
