Ayurvedic Treatment in the Rehabilitation of Ischemic Stroke Patients in India: A Randomized Controlled Trial Study Protocol

In patients with ischemic stroke, motor and sensory impairments are common and are associated with functional disability. Conventional physiotherapy (CP) is the primary modality of rehabilitation for post-stroke sensorimotor dysfunction. Ayurveda is a commonly practiced alternative system of medicine that offers unique rehabilitative measures for post-stroke recovery. We hypothesize that Ayurvedic rehabilitative treatment (ART) is superior to similar duration CP in improving the sensorimotor recovery of patients with ischemic stroke at 90 days after enrollment. AyuRvedic TrEatment in the Rehabilitation of Ischemic STrOke Patients in India: A Randomized controllEd trial (RESTORE) is an investigator-initiated, multicenter, prospective, randomized, controlled, parallel-arm, blinded outcome assessment trial being conducted under the Indian Stroke Clinical Trial (INSTRuCT) Network across the four comprehensive stroke centers in India. Consecutive hemodynamically stable adult patients with their first acute ischemic stroke between 1 and 3 months from stroke onset are being randomized (1:1) into two treatment groups to receive either 1 month of ART or 1 month of CP. The primary outcome measure is the Fugl Meyer Assessment-upper extremity for physical performance at 90 days. The secondary outcomes are the modified Rankin Scale, Barthel Index, Berg Balance, and SF-36 at 90 days. The safety outcomes include a composite of irreversible morbidity and mortality. A sample size of 140 (70 in each group) patients with ischemic stroke will allow us to detect a minimal clinical important difference of 9.4 (standard deviation) with superiority margin of 5, an attrition rate of 10%, alpha of 5%, and power of 80%. This randomized trial will systematically assess the efficacy and safety of traditional ART compared to CP. The trial has been registered in the Clinical Trial Registry India (CTRI/2018/04/013379).

Effectiveness of an oral health education intervention among 6-12-year-old children: A cluster randomized controlled trial

OBJECTIVES

Literature on the effectiveness of theory-based oral health education on the oral hygiene of children is limited. We aimed to determine the effectiveness of an health behaviour theory-based school oral health education intervention on 1) oral hygiene and 2) oral health-related knowledge, attitude and practices among 6-12-year-old children in Kerala, India.

METHODS

Cluster randomized controlled trial. Sixteen class divisions (clusters) were randomized into intervention and control groups of 225 and 228 children respectively. Primary and secondary outcomes were plaque score as measured using the simplified oral hygiene index (OHI-S) and oral health-related knowledge, attitude and practices respectively. The intervention group received structured oral health education classes for three months and materials including pamphlets. Children in the control group were not given the classes or materials.

RESULTS

Post-intervention OHI-S scores in the intervention group and control groups were 1.65 and 2.17 respectively (difference = -0.52, 95%CI -0.86, -0.18). All the secondary outcomes improved in the intervention group compared to the control group.

CONCLUSIONS

The intervention improved the oral hygiene status, oral health-related knowledge, attitude and practices of the children. Longer term follow-up and economic appraisal are needed to help policymakers plan and develop OHEI based on health behaviour theories.

Effectiveness of a School-Based Educational Intervention to Improve Hypertension Control Among Schoolteachers: A Cluster-Randomized Controlled Trial

Background The control of hypertension is low in low- and middle-income countries like India. We evaluated the effects of a nurse-facilitated educational intervention in improving the control rate of hypertension among school teachers in India. Methods and Results This was a cluster-randomized controlled trial involving 92 schools in Kerala, which were randomly assigned equally into a usual care group and an intervention group. Participants were 402 school teachers (mean age, 47 years; men, 29%) identified with hypertension. Participants in both study groups received a leaflet containing details of a healthy lifestyle and the importance of regular intake of antihypertensive medication. In addition, the intervention participants received a nurse-facilitated educational intervention on hypertension control for 3 months. The primary outcome was hypertension control. Key secondary outcomes included systolic blood pressure, diastolic blood pressure, and the proportion of participants taking antihypertensive medications. For the primary outcome, we used mixed-effects logistic regression models. Two months after a 3-month educational intervention, a greater proportion of intervention participants (49.0%) achieved hypertension control than the usual care participants (38.2%), with an odds ratio of 1.89 (95% CI, 1.06-3.35), after adjusting for baseline hypertension control. The odds of taking antihypertensive medications were 1.6 times higher in the intervention group compared with the usual care group (odds ratio, 1.62; 95% CI, 1.08-2.45). The reduction in mean systolic blood pressure was significantly greater in the intervention group by 4.2 mm Hg (95% CI, -7.2 to -1.1) than in the usual care group. Conclusions A nurse-facilitated educational intervention was effective in improving the control and treatment rates of hypertension as well as reducing systolic blood pressure among schoolteachers with hypertension.

Validation of Malayalam Version of Everyday Abilities Scale for India

BACKGROUND

Cognitive impairment is usually associated with impairment in everyday activities. Scales to assess activities of daily living, like the Everyday Abilities Scale for India (EASI), have been employed as screening tools for dementia or major neurocognitive disorder. EASI had not been validated in Malayalam. This study's objective was to validate the Malayalam version of EASI (M-EASI) in those aged ≥60 years.

METHODS

In a study undertaken in a tertiary care center, those aged ≥60 years attending psychiatry, neurology, or geriatric clinic of general medicine departments were evaluated using M-EASI and the Malayalam version of Addenbrooke's Cognitive Examination (M-ACE). A total of 304 participants were recruited for this questionnaire validation. Information for M-EASI was obtained from a reliable informant.

RESULTS

The mean age of the sample was 70.04 years (standard deviation-7.33). The majority of them were males (58.6%) and educated up to primary school (42.4%), while the majority of the informants were sons/daughters/siblings (47.7%) and were females (73.7%). Taking M-ACE scores as the gold standard for diagnosing MNCD according to Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition criteria, there were 162 cases of MNCD and 142 normal controls. Cronbach's α was 0.91. At an optimal cut-off of 4.5, adequate sensitivity (77.8%), and specificity (75.4%) were observed. The positive predictive value was 78.6%, and the negative predictive value, 74.5%.

CONCLUSION

M-EASI has adequate psychometric properties as a screening tool for MNCD.

Determinants of Suboptimal Outcome Following Thymectomy in Myasthenia Gravis

Background

Response to thymectomy in myasthenia gravis (MG) is influenced by various patient-, disease-, and therapy-related factors.

Methods

Retrospective analysis of 128 patients with MG who underwent maximal thymectomy over 15 years was done to identify the determinants of suboptimal clinical outcome.

Results

Among the 128 patients, 62 (48.4%) were females with a mean age of 38.97 (12.29) years. Thymomatous MG occurred in 66 (51.6%). Overall improvement from preoperative status was noted in 88 (68.8%) patients after mean follow-up of 51.68 (33.21) months. The presence of thymoma was the major predictor of suboptimal clinical outcome (P = 0.001), whereas age, gender, preoperative disease severity, and seropositive status did not attain significance. Patients with better outcome had received higher steroid dose preoperatively (P = 0.035).

Conclusions

Suboptimal response after thymectomy occurred in one-third of MG patients, more commonly with thymomatous MG. Relationship of preoperative steroid therapy to remission merits evaluation.

Life Style and Behavioural Factors are Associated with Stroke Recurrence Among Survivors of First Episode of Stroke: A Case Control Study

BACKGROUND

Secondary stroke prevention treatment is associated with an 80% reduction in risk of recurrent stroke. But one out of every four strokes are recurrent. Adherence to pharmacological therapy and strict control of risk factors are essential for prevention of recurrent strokes.

METHODS

Pair matched incident case control study was done to find out the factors associated with stroke recurrence after first ever stroke. Incident cases of recurrent strokes and age and post stroke period matched controls were recruited prospectively. The estimated sample size for the study was 70 matched pairs. Data collected from medical records and by visiting their homes. Analysis was done using R statistical software.

RESULTS

Bivariate analysis showed cardio embolic stroke subtype, poor lipid control, unhealthy diet, physical inactivity, medication nonadherence, presence of depression, memory problems no discharge advice at index admission and low income were associated increased risk of recurrence. Higher mean NIHSS score and a greater number of days of hospitalisation during index stroke had less risk of recurrence. Conditional logistic regression analysis revealed non adherence to medication (OR 7.46, 1.67-33.28) and not receiving discharge advice at index admission (OR 10.79, 2.38-49.02) were associated with increased risk of recurrence whereas lacunar stroke (OR 0.08, 0.01-0.59) and a greater number of days of hospitalization during index stroke (OR 0.82, 0.67-0.99) were associated with less risk of recurrence.

CONCLUSION

Individualised patient education regarding stroke, recurrence risk, medication adherence, healthy lifestyle and risk factor control can reduce stroke recurrence risk.

Multi-morbidity and blood pressure control: Results of a cross-sectional study among school teachers in Kerala, India

The patterns of concordant and discordant comorbidities of hypertension and their association with hypertension control were ascertained in this cross-sectional study. A total of 402 adults with hypertension were identified from the baseline survey of a randomized controlled trial for hypertension control among school teachers in Kerala. Chronic conditions were captured and categorized into concordant and discordant comorbidities. Nearly 57% of teachers with hypertension reported multimorbidity. Concordant morbidity was reported by 44% and discordant by 21% of participants. The odds of hypertension control was higher among those who reported at least one discordant morbidity (odds ratio [OR]: 2.76, 95% confidence interval [CI]:1.69-4.49) and those who reported at least one concordant morbidity (OR: 2.08, CI: 1.37-3.16), compared to their counterparts. Hypertension control was higher for those who reported any comorbidity (OR: 2.37, CI: 1.51-3.71) compared to those who did not report any. Well-designed large-scale mixed methods studies are required to thoroughly explore multimorbidity and its relationship with hypertension control in India.

Antiplatelets versus Anticoagulants in the Treatment of Extracranial Carotid and Vertebral Artery Dissection

Background

Very few studies have compared the safety and efficacy of antiplatelets and anticoagulants in the treatment of extracranial carotid and vertebral artery dissection. Our study was aimed at comparing the two types of antithrombotic treatment in extracranial dissection and to study the predictors of outcome in these patients.

Materials and Methods

Prospective data of 200 consecutive patients with a confirmed diagnosis of extracranial carotid (n = 132) or vertebral (n = 68) artery dissection (76% males; mean age, 43.5 ± 13 years) treated with antiplatelets (n = 136) or anticoagulants (n = 64) were analyzed retrospectively. The presenting symptom was stroke in 74.5%, transient ischemic attack (TIA) in 18.5%, and local symptoms in 7% of the patients. Follow-up was done at three and six months. Primary outcome measures were TIA or stroke and symptomatic intracerebral hemorrhage (SICH) at three months.

Results

At the three-month follow-up, 106 (53%) patients had an excellent outcome. Recurrent ischemic events occurred in 7 (3.5%) and SICH in 11 (5.55%) patients. Six (4.41%) patients in the antiplatelet group and 1 patient (1.56%) in the anticoagulant group had recurrent ischemic events (P = 0.434); SICH was more frequent in the anticoagulant group (9.4% vs 3.7%, P = 0.185). On multivariate analysis, significant predictors of a poor three-month outcome were stroke as the presenting event and severity of stroke at onset.

Conclusions

The risk of recurrent ischemic events in carotid and vertebral artery dissection is low and is irrespective of the type of antithrombotic treatment. Stroke as the presenting event and severity of stroke at onset were significant predictors of a poor three-month outcome.

Do women with epilepsy benefit from epilepsy specific pre-conception care?

BACKGROUND

To determine how pre-conception care (PCC) influenced the outcome of epilepsy, pregnancy and malformation risk in women with epilepsy (WWE).

METHODS

All primigravida in the Kerala registry of epilepsy and pregnancy (KREP) with the final outcome of pregnancy known who were enrolled prospectively in pre-conception stage (PCC group) or first trimester of pregnancy (PRG group) were included. The two groups were compared for fetal and maternal outcomes including seizure control and complications of pregnancy.

RESULTS

There were 320 (30.4 %) in PCC group and 732 in PRG group. Both groups were comparable for epilepsy classification, maternal birth defects and family history of epilepsy but the PCC group had significantly higher education (48.9 %, p = .027) and employment (22.1 %, p < .001). They had higher usage of folate in pre-pregnancy month (87.5 %, p < .001) and first trimester (96.3 %, p < .001) than PRG group. Fewer women in the PCC group were off AEDs in first trimester (5 % vs 9.3 %, p = .018). Within monotherapy group, use of levetiracetam (10.8 %, p = .017), valproate (34 %, p = .002) in PCC group and carbamazepine (39.1 %, p = .04), phenobarbitone (13.3 %, p = .001) in PRG group was significantly high. More women in PCC group were seizure free during pregnancy (62.8 %, p = .005) than PRG group. Early fetal loss was better captured in PCC (90.6 %,p = .025) than in the PRG. There was no difference in malformation rate between PCC (7.2 %) and PRG groups (6.1 %, p = .3).

CONCLUSION

PCC reduced the risk of seizures during pregnancy and improved the periconceptional use of folate but did not influence the fetal malformation risk.

Cluster randomised controlled trial of behavioural intervention program: a study protocol for control of hypertension among teachers in schools in Kerala (CHATS-K), India

Background

Control of blood pressure among hypertensives is a major challenge around the world. Interventions for improving hypertension control in India are very limited. This paper describes the protocol for a cluster randomized controlled trial of efficacy of behavioural intervention on control of hypertension among school teachers in Kerala.

Methods

A total of 92 schools are randomised to intervention and control group in Kerala. A baseline survey was conducted in all schools to assess the prevalence of hypertension and its risk factors among school teachers in Thiruvananthapuram district of Kerala state, India. Teachers in both sets of schools will receive a leaflet containing details on the importance of controlling hypertension. With the objective of improving control of hypertension, the intervention schools will additionally receive self-management education and behavioural intervention programs delivered by trained intervention managers along with measurement of weight, waist circumference and blood pressure. This intervention program will be developed based on the findings of the baseline survey and selected components of successful models of hypertension control from previous research done in similar settings. The intervention will be given for 3 months after which a post-survey will be conducted among teachers of both control and intervention schools. The primary outcome is change in control of hypertension and secondary outcome is the change in behavioural risk factors of hypertension both in the control and intervention groups.

Discussion

This is the first comprehensive study looking at the efficacy of behavioural intervention on hypertension control among school teachers in Kerala, India. This study is likely to provide an upper estimate of behavioural intervention on hypertension control since teachers are reported to have one of the highest compliance rates of behavioural intervention.

Trial registration

This trial was prospectively registered with the Clinical Trials Registry of India [CTRI/2018/01/011402] on 18 January 2018.

Prevalence of risk factors of non-communicable diseases in Kerala, India: results of a cross-sectional study

OBJECTIVE

To estimate the prevalence of non-communicable disease (NCD) risk factors in Kerala.

DESIGN

A community-based, cross-sectional survey.

PARTICIPANTS

In 2016-2017 a multistage, cluster sample of 12 012 (aged 18-69 years) participants from all 14 districts of Kerala were studied.

MAIN OUTCOME MEASURES

NCD risk factors as stipulated in the WHO's approach to NCD risk factors surveillance were studied. Parameters that were studied included physical activity score, anthropometry, blood pressure (BP), and fasting blood glucose (FBG) and morning urine sample to estimate dietary intake of salt.

RESULTS

The mean age was 42.5 years (SD=14.8). Abdominal obesity was higher in women (72.6%; 95% CI 70.7 to 74.5) compared with men (39.1%; 95% CI 36.6 to 41.7), and also higher among urban (67.4%; 95% CI 65.0 to 69.7) compared with rural (58.6%; 95% CI 56.6 to 60.5) residents. Current use of tobacco and alcohol in men was 20.3% (95% CI 18.6 to 22.1) and 28.9% (95% CI 26.5 to 31.4), respectively. The estimated daily salt intake was 6.7 g/day. The overall prevalence of raised BP was 30.4% (95% CI 29.1 to 31.7) and raised FBG was 19.2% (95% CI 18.1 to 20.3). Raised BP was higher in men (34.6%; 95% CI 32.6 to 36.7) compared with women (28%; 95% CI 26.4 to 29.4), but was not different between urban (33.1%; 95% CI 31.3 to 34.9) and rural (29.8%; 95% CI 28.3 to 31.3) residents. Only 12.4% of individuals with hypertension and 15.3% of individuals with diabetes were found to have these conditions under control. Only 13.8% of urban and 18.4% of rural residents did not have any of the seven NCD risk factors studied.

CONCLUSION

Majority of the participants had more than one NCD risk factor. There was no rural-urban difference in terms of raised BP or raised FBG prevalence in Kerala. The higher rates of NCD risk factors and lower rates of hypertension and diabetes control call for concerted primary and secondary prevention strategies to address the future burden of NCDs.

Overweight, the major determinant of metabolic syndrome among industrial workers in Kerala, India: Results of a cross-sectional study

AIM

To determine the prevalence and associated risk factors of metabolic syndrome (MS) among industrial workers in Kerala, India.

MATERIALS AND METHODS

We measured fasting plasma glucose (FPG), triglycerides, high density lipoprotein cholesterol, waist circumference, systolic blood pressure and diastolic blood pressure among 2287 industrial workers (mean age 46 years, men 70%) from selected industries of two southern most Kerala districts using standard protocol in 2009. MS was defined according to international diabetes federation (IDF), Adult Treatment Panel (ATP-III) and American Heart Association(AHA)/National Heart Lung and Blood Institute (NHLBI) criteria (Harmonization). Age-standardized prevalence of MS was assessed for men and women. Multivariable logistic regression models were developed to find the associated factors of MS.

RESULTS

Age-standardized prevalence of MS was 14% (men 14%, women 15%), 19% (men 19%, women 21%) and 27% (men 30%, women 21%) as per IDF, ATP-III and Harmonization criteria respectively. Overweight adults were nine times (OR 9.41, 95% CI 7.34-12.06), twelve times (OR 11.80 CI 9.38-14.84), and four times (OR 3.56, CI 2.94-4.29) more likely to have MS compared to their counterparts according to IDF, ATP-III and Harmonization criteria respectively. Older adults and current alcohol users were more likely to have MS compared to their counterparts. Women were more likely to have MS as per IDF and ATP-III criteria.

CONCLUSIONS

MS prevalence was high among Industrial workers who generally have good access to health care. Overweight and other predictors of MS need to be addressed to reduce MS prevalence in this population.

Predictors of dementia-free survival after bilateral subthalamic deep brain stimulation for Parkinson's disease

Objective

Bilateral subthalamic nucleus deep brain stimulation (STN DBS) improves motor complications and quality of life (QOL) in patients with Parkinson's disease (PD). However, it does not delay or prevent the occurrence of dementia. The deleterious effects of dementia on QOL and activities of daily living (ADL) underscore the importance of identifying predictors of dementia-free survival in PD patients considered for STN DBS.

Aims and Methods

The baseline clinical and neuropsychological data and the occurrence of dementia recorded during the longitudinal follow-up of a cohort of patients with PD with at least 2 years follow-up after bilateral STN DBS, were reviewed.

Results

One hundred and sixteen patients operated between 1999 to 2014 satisfied the inclusion criteria. Their mean age was 56.5 (±10) years and the mean duration of PD at surgery was 11.2 (±4.2) years. During the 542 person-years of follow-up, 30 patients developed dementia. The mean dementia-free survival after surgery was 8.7 [95% confidence interval (CI): 7.8-9.6] years. In univariate analysis, the baseline factors of older age, longer disease duration, past history of depression or psychosis, freezing of gait in OFF phase, worse ADL scores in ON phase, lower levodopa response of the Unified Parkinson's Disease Rating Scale (UPDRS) III axial sub-scores, and poor performances in the Addenbrooke's Cognitive Examination and Wisconsin Card Sorting Test (WCST) were associated with a shorter dementia-free survival. Among these, only freezing of gait and poor performance in WCST were independent predictors.

Conclusion

Presence of freezing of gait in the drug OFF state and executive dysfunction predict the occurrence of earlier dementia in PD patients who otherwise qualify for bilateral STN DBS.

Alignment efficiency of coaxial tubular superelastic nickel-titanium vs single-stranded superelastic nickel-titanium in relieving mandibular anterior crowding in extraction cases: A single-centre randomized controlled clinical trial

OBJECTIVES

To compare the alignment efficiency of coaxial tubular and single-stranded 0.016" superelastic NiTi archwires in relieving mandibular anterior crowding in extraction cases and to evaluate whether alignment efficiency differed as the initial irregularity increased.

SETTING AND SAMPLE POPULATION

Forty female patients aged between twelve and twenty years from the postgraduate orthodontic clinic at the authors' centre.

MATERIALS AND METHODS

All patients in this single-centre, 2-arm parallel trial were randomly allocated in a 1:1 ratio and the mandibular anterior irregularity was measured from the mandibular cast at 0-, 4-, 8- and 12-week intervals using a digital calliper.

RESULTS

All forty patients (mean age, 15.08 ± 2.11) completed the study with either coaxial tubular superelastic NiTi (mean age, 15.30 ± 2.36) or single-stranded superelastic NiTi (mean age, 14.85 ± 1.84). The largest mean irregularity index reduction of -4.88 ± 2.74 and -6.17 ± 2.38 in the single-stranded superelastic NiTi and the coaxial tubular superelastic NiTi groups, respectively (P = 0.122) was at 4 weeks. Student's t test and repeated measures ANOVA indicated that none of the mean comparisons were statistically significant at a 5% level. Pearson's correlation value (r) indicated no statistically significant influence of initial crowding on alignment efficiency.

CONCLUSIONS

There was no statistically significant difference between the alignment efficiency of coaxial tubular superelastic NiTi and single-stranded superelastic NiTi in extraction cases, and the degree of initial crowding had no influence on the alignment efficiency.

Central disorders of hypersomnolence in children and adults: A comparative study from South India

Background:

Narcolepsy and idiopathic hypersomnolence (IHS) are rare disorders. In Western populations, the reported prevalence of narcolepsy is 0.02%–0.05%. In Indian subcontinent, there are few reports on narcolepsy and none on IHS so far. Here, we compared the clinical and polysomnographic profile of narcolepsy/IHS among the pediatric and adult groups.

Materials and Methods:

The patients presenting with excessive daytime sleepiness (EDS) attending sleep clinic from January 2010 to December 2015 were included. Patients were diagnosed with narcolepsy type 1 (NT1), narcolepsy type 2 (NT2), and IHS based on the International Classification for Sleep Disorders criteria. Patients with secondary causes of EDS were excluded from the study.

Results:

A total of 56 patients were included in the study (29 males and 27 females). The mean age of symptom onset was 29 years (males – 34 years and females – 24 years). Twelve (21%) patients had NT1, five (9%) patients had NT2, whereas 38 (68%) patients had IHS compared to narcolepsy, the IHS had an older mean age at presentation. The average time from symptom onset to diagnosis was 71 months. Classical tetrad of narcolepsy was rarely found in pediatric cohort, but they had more behavioral problems and weight gain. Pediatric cohort of IHS also reported behavioral problems. The mean sleep-onset latency was 3.1 min, while the mean rapid eye movement latency was 7.2 min.

Conclusion:

The pediatric narcolepsy patients tend to have less classical symptoms and more behavioral/eating problems as compared to adult cohort. There is significant delay in diagnosing narcolepsy, indicating the need to increase awareness among the physicians about this rare treatable disorder.

Determinants of compulsory admissions in a state psychiatric hospital-Case control study

OBJECTIVE

Compulsory admissions are against the patient's will and are presumably due to diverse reasons. There has been a rise in compulsory admissions world over. The objective of the study was to determine the risk factors for compulsory admissions in a state psychiatric hospital.

METHODS

A case control study was conducted at the state psychiatric hospital, Trivandrum, Kerala. Cases were involuntary non-legal admissions while controls were voluntary admissions. Putative risk factors studied included social support, severity of psychopathology etc., in addition to the socio-demographic variables.

RESULTS

Risk factors for compulsory admissions were higher age, 30-49 years, OR=1.98, 95% CI [1.03-3.81]; >50years, OR=2.2, 95% CI [1.03-4.72], being from an urban locale,OR=1.99, 95% CI [1.13-3.52], living in joint & extended families OR=2.12, 95% CI [1.3-3.4], homelessness OR=2.24, 95% CI [1.32-3.79] and poor social support, OR=4.45 [2.53-7.81]. The type of illness, its duration, diagnosis, or symptom severity were not significantly related to compulsory admissions, but past compulsory admissions OR=5.36, 95% CI [2.09-13.75], poor functioning OR=2.54, 95% CI [1.31-4.91] and poor compliance to medication OR=1.78, 95% CI [1.05-3.01] were associated with compulsory admission. Poor social support, past involuntary admissions and poor functional status retained their association after multivariate analysis.

CONCLUSIONS

By addressing the modifiable factors like poor social support, poor functional status, and poor compliance to medication, compulsory admissions could be prevented. Since it is found that compulsory admissions are likely to repeat, such patients form a high risk group requiring specific interventions.

Teratogenicity of antiepileptic dual therapy: Dose-dependent, drug-specific, or both?

OBJECTIVE

To determine the relative risk (RR) of major congenital malformations (MCMs) in infants with antenatal exposure to antiepileptic drug (AED) dual therapy and to explore the influence of specific AEDs vs dose.

METHODS

All completed pregnancies prospectively enrolled in the Kerala Registry of Epilepsy and Pregnancy from 1998 until December 2013 on AED dual therapy exposure during the first trimester were analyzed for the outcome, MCMs. Dose was expressed as ratio of prescribed to daily defined dose (PDD/DDD), and the RR for malformation was referenced to lamotrigine monotherapy.

RESULTS

Of 1,688 completed pregnancies, 368 women were on dual therapy. The risk of MCM with dual therapy was 1.6 times more than with monotherapy (p = 0.0015). The frequency of renal, alimentary, and skeletal malformations was higher with dual therapy, while cardiac malformations were more common with monotherapy. The risk of MCM was highest with topiramate dual therapy (14.82, 95% confidence interval [CI] 1.88-113.83). No MCMs were seen with levetiracetam or lamotrigine dual therapy. There was a marked reduction in the risk of MCM when dual therapies involving topiramate or valproate were excluded (RR 1.78, 95% CI 1.00-3.15). The risk of MCM with dual therapy was higher even at lower doses (8.2%, PDD/DDD 0.5-1), and the subsequent dose-dependent increment was less profound than with monotherapy.

CONCLUSIONS

Our data indicate that the excess risk of dual therapy over monotherapy is contributed largely by topiramate or valproate. The complex pharmacokinetic and pharmacodynamic effects of dual therapy adversely influence MCM risk.

Pattern of tobacco use and its correlates among older adults in India

PURPOSE

We examined tobacco use pattern and its correlates among older adults.

MATERIALS AND METHODS

We used data of 9,852 older adults (>=60 years) (men 47% mean age 68 years) collected by the United Nations Population Fund on Ageing from seven Indian states. Logistic regression analysis was used to assess the correlates of tobacco use.

RESULTS

Current use of any form of tobacco was reported by 27.8% (men 37.9%, women 18.8%); 9.2% reported only smoking tobacco, 16.9% smokeless tobacco only and 1.7% used both forms. Alcohol users (OR:5.20, 95% CI:4.06-6.66), men (OR:2.92, CI :2.71-3.47), those reporting lower income (OR:2.74, CI:2.16- 3.46), rural residents (OR 1.34, CI 1.17-1.54) and lower castes (OR:1.29, CI:1.13-1.47) were more likely to use any form of tobacco compared to their counterparts.

CONCLUSIONS

Tobacco cessation interventions are warranted in this population focusing on alcohol users, men, those from lower income, rural residents and those belonging to a lower caste.

Development of a Tool to Stage Households' Readiness to Change Dietary Behaviours in Kerala, India

Dietary interventions and existing health behaviour theories are centred on individuals; therefore, none of the available tools are applicable to households for changing dietary behaviour. The objective of this pilot study was to develop a practical tool that could be administered by community volunteers to stage households in rural Kerala based on readiness to change dietary behaviour. Such a staging tool, comprising a questionnaire and its algorithm, focusing five dietary components (fruits, vegetables, salt, sugar and oil) and households (rather than individuals), was finalised through three consecutive pilot validation sessions, conducted over a four-month period. Each revised version was tested with a total of 80 households (n = 30, 35 and 15 respectively in the three sessions). The tool and its comparator, Motivational Interviewing (MI), assessed the stage-of-change for a household pertaining to their: 1) fruit and vegetable consumption behaviour; 2) salt, sugar and oil consumption behaviour; 3) overall readiness to change. The level of agreement between the two was tested using Kappa statistics to assess concurrent validity. A value of 0.7 or above was considered as good agreement. The final version was found to have good face and content validity, and also a high level of agreement with MI (87%; weighted kappa statistic: 0.85). Internal consistency testing was performed using Cronbach’s Alpha, with a value between 0.80 and 0.90 considered to be good. The instrument had good correlation between the items in each section (Cronbach’s Alpha: 0.84 (fruit and vegetables), 0.85 (salt, sugar and oil) and 0.83 (Overall)). Pre-contemplation was the most difficult stage to identify; for which efficacy and perceived cooperation at the household level were important. To the best of our knowledge, this is the first staging tool for households. This tool represents a new concept in community-based dietary interventions. The tool can be easily administered by lay community workers and can therefore be used in large population-based studies. A more robust validation process with a larger sample is needed before it can be widely used.

Collateral Assessment by CT Angiography as a Predictor of Outcome in Symptomatic Cervical Internal Carotid Artery Occlusion

BACKGROUND AND PURPOSE

Cervical internal carotid artery occlusion can present with varied clinical manifestations such as transient ischemic attack, stroke, and chronic ocular ischemia, or can be asymptomatic. The outcome in these patients is considerably influenced by cerebral hemodynamic compensatory adaptation of the intracranial collateral pathways. Our aim was to study whether collateral circulation as assessed by CT angiography can predict 3-month outcome and initial stroke severity in patients with symptomatic cervical ICA occlusion.

MATERIALS AND METHODS

This was a retrospective study of 65 patients with symptomatic cervical ICA occlusion from January 2011 to December 2013. The collateral vessels (anterior and posterior communicating arteries, ophthalmic artery, and leptomeningeal arteries) were assessed by CTA. The outcome at 3 months was defined as poor if the modified Rankin Scale score was ≥3.

RESULTS

The mean age of subjects was 57 ± 11.6 years (range, 32-80 years), and 92% were men. Thirty-three (50.8%) patients had poor outcome. Absence of the ipsilateral ophthalmic artery, poor leptomeningeal collaterals, and <2 collaterals were predictors of stroke severity at onset and poor 3-month outcome in univariate analysis. In the multiple logistic regression analysis, inadequate flow through the secondary collaterals (ipsilateral ophthalmic artery or leptomeningeal collaterals; OR, 4.5; 95% CI, 1.4-14.9; P = .01) and higher NIHSS score at stroke onset (OR, 19.2; 95% CI, 2.2-166.2; P = .007) independently predicted poor outcome at 3 months.

CONCLUSIONS

Assessment of collateral circulation with CTA can be a useful predictor of 3-month outcome in patients with symptomatic cervical ICA occlusion.

Assessment of long-term impact of formal certified cardiopulmonary resuscitation training program among nurses

CONTEXT

Cardiopulmonary resuscitation (CPR) and emergency cardiovascular care guidelines are periodically renewed and published by the American Heart Association. Formal training programs are conducted based on these guidelines. Despite widespread training CPR is often poorly performed. Hospital educators spend a significant amount of time and money in training health professionals and maintaining basic life support (BLS) and advanced cardiac life support (ACLS) skills among them. However, very little data are available in the literature highlighting the long-term impact of these training.

AIMS

To evaluate the impact of formal certified CPR training program on the knowledge and skill of CPR among nurses, to identify self-reported outcomes of attempted CPR and training needs of nurses.

SETTING AND DESIGN

Tertiary care hospital, Prospective, repeated-measures design.

SUBJECTS AND METHODS

A series of certified BLS and ACLS training programs were conducted during 2010 and 2011. Written and practical performance tests were done. Final testing was undertaken 3-4 years after training. The sample included all available, willing CPR certified nurses and experience matched CPR noncertified nurses.

STATISTICAL ANALYSIS USED

SPSS for Windows version 21.0.

RESULTS

The majority of the 206 nurses (93 CPR certified and 113 noncertified) were females. There was a statistically significant increase in mean knowledge level and overall performance before and after the formal certified CPR training program (P = 0.000). However, the mean knowledge scores were equivalent among the CPR certified and noncertified nurses, although the certified nurses scored a higher mean score (P = 0.140).

CONCLUSIONS

Formal certified CPR training program increases CPR knowledge and skill. However, significant long-term effects could not be found. There is a need for regular and periodic recertification.

Adapting and Validating the Global Physical Activity Questionnaire (GPAQ) for Trivandrum, India, 2013

Introduction

A limitation of the Global Physical Activity Questionnaire (GPAQ) in assessing physical activity in India is that it does not capture the diversity of activities across cultures and by sex. The purpose of this study was to culturally adapt and validate the GPAQ by using an accelerometer in Thiruvananthapuram City, India.

Methods

We developed a modified version of the GPAQ by adding a physical activity chart specific to the locale. We identified local physical activities through in-depth interviews, group discussions, and observation, and used Actigraph GT3X accelerometers to validate the modified GPAQ for a subsample of 47 women. Participants were drawn from a cross-sectional survey of 1,303 women aged 18 to 64 years, selected by multistage cluster sampling. Spearman rank correlation coefficients and intraclass correlation coefficients (ICC) were calculated to determine the correlation and level of agreement in moderate-to-vigorous physical activity (MVPA) on the basis of accelerometer measurement and the modified GPAQ.

Results

The correlation for MVPA between the modified GPAQ (overall) and the accelerometer (non-bouted MVPA) was 0.69 (95% confidence interval [CI], 0.39–0.85) with a moderately high ICC of 0.78 (95% CI, 0.56–0.90). The correlation for MVPA between the modified GPAQ and the accelerometer-based MVPA within bouts of at least 10 minutes was 0.60 (95% CI, 0.26–0.80) with an ICC of 0.55 (95% CI, 0.20–0.77) indicating a moderate level of agreement.

Conclusion

The GPAQ can be used for assessing physical activity among women in India, and its adaptation and validation may be useful in other low-income or middle-income countries where activities are diverse in type and intensity.

Utilization of maternal health care services in post-conflict Nepal

Background

Despite a decade-long armed conflict in Nepal, the country made progress in reducing maternal mortality and is on its way to achieve the Millennium Development Goal Five. This study aimed to assess the degree of the utilization of maternal health care services during and after the armed conflict in Nepal.

Methods

This study is based on Nepal Demographic and Health Survey data 2006 and 2011. The units of analysis were women who had given birth to at least one child in the past 5 years preceding the survey. First, we compared the utilization of maternal health care services of 2006 with that of 2011. Second, we merged the two data sets and applied logistic regression to distinguish whether the utilization of maternal health care services had improved after the peace process 2006 was underway.

Results

In 2011, 85% of the women sought antenatal care at least once. Skilled health workers for delivery care assisted 36.1% of the women, and 46% of the women attended postnatal care visit at least once. These figures were 70%, 18.7%, and 16%, respectively, in 2006. Similarly, women were more likely to utilize antenatal care at least once (odds ratio [OR] =2.18, confidence interval [CI] =1.95–2.43), skilled care at birth (OR =2.58, CI =2.36–2.81), and postnatal care at least once (OR =4.13, CI =3.75–4.50) in 2011.

Conclusion

The utilization of maternal health care services tended to increase continuously during both the armed conflict and the post-conflict period in Nepal. However, the increasing proportion of the utilization was higher after the Comprehensive Peace Process Agreement 2006.

Construction and Validation of a Women's Autonomy Measurement Scale with Reference to Utilization of Maternal Health Care Services in Nepal

INTRODUCTION

Women's autonomy is one of the predictors of maternal health care service utilization. This study aimed to construct and validate a scale for measuring women's autonomy with relevance to developing countries.

METHODS

We conducted a study for construction and validation of a scale in Rupandehi and further validated in Kapilvastu districts of Nepal. Initially, we administered a 24-item preliminary scale and finalized a 23-item scale using psychometric tests. After defining the construct of women's autonomy, we pooled 194 items and selected 24 items to develop a preliminary scale. The scale development process followed different steps i.e. definition of construct, generation of items pool, pretesting, analysis of psychometric test and further validation.

RESULTS

The new scale was strongly supported by Cronbach's Alpha value (0.84), test-retest Pearson correlation (0.87), average content validity ratio (0.8) and overall agreement- Kappa value of the items (0.83) whereas all values were found satisfactory. From factor analysis, we selected 23 items for the final scale which show good convergent and discriminant validity. From preliminary draft, we removed one item; the remaining 23 items were loaded in five factors. All five factors had single loading items by suppressing absolute coefficient value less than 0.45 and average coefficient was more than 0.60 of each factor. Similarly, the factors and loaded items had good convergent and discriminant validity which further showed strong measurement capacity of the scale.

CONCLUSIONS

The new scale is a reliable tool for assessing women's autonomy in developing countries. We recommend for further use and validation of the scale for ensuring the measurement capacity.

Effect of a self-instructional module on the child rearing knowledge and practice of women with epilepsy

Women with epilepsy (WWE) have poorer knowledge and skill in child rearing than women without epilepsy.

PURPOSE

To evaluate the effect of a self-instructional module (SIM) on the child rearing knowledge (CRK) and practice (CRP) of WWE and developmental outcome of their babies.

METHODS

One hundred women in first trimester of pregnancy that were enrolled in to the Kerala Registry of Epilepsy and Pregnancy and consenting to participate were given a self instructional module (SIM) or a comparator booklet by random concealed allocation. Their child rearing knowledge (CRK) was assessed by a standardized protocol at entry (first trimester) and at 3-4 months postpartum. Their child rearing practice (CRP) was evaluated in third postpartum month. The developmental outcome of babies was assessed at 1 year of age as per registry protocol.

RESULTS

Eighty eight women completed this 1 year study. The CRK score was significantly higher (p=.034) for the intervention group (32.91±5) when compared to the comparator group (30.61±5) However, a corresponding improvement in CRP score was not observed for the former. Developmental outcome of 68 babies showed a positive weak correlation between CRP and developmental quotient both mental and motor. The intervention group demonstrated significant increase in their CRK. Nevertheless the results did not indicate a significant improvement in the CRP.

CONCLUSION

The SIM improved the CRK of WWE. Nevertheless, the child rearing practices did not show corresponding improvement.

Women with epilepsy and infertility have different reproductive hormone profile than others

Purpose:

One-third of women with epilepsy (WWE) may experience infertility (failure to conceive after 12 months of regular unprotected intercourse). We aimed to compare the hormone profile of WWE and infertility (WWE-I) with that of WWE who had conceived earlier (WWE-F).

Materials and Methods:

In the Kerala Registry of Epilepsy and Pregnancy, we compared the clinical and hormone profile of 50 WWE-I and 40 age-matched WWE-F. Subjects were examined and blood samples were drawn in follicular phase (1-14 days) for 21 WWE-I and 18 WWE-F, in luteal phase (15-30 days) for 23 WWE-I and 15 WWE-F and beyond 30 days for 6 WWE-I and WWE-F who had irregular cycles.

Results:

The two groups were comparable regarding physical, epilepsy syndrome, duration of epilepsy, body mass index, and serum cholesterol levels. Menstrual periods were irregular for 6 WWE-I and 5 WWE-F. The WWE-I group (compared to the WWE-F group) had significantly (P < 0.01) higher levels of dehydroepiandrostenedione (2.0 ± 1.7 ug/mL vs. 1.0 ± 0.7 ug/mL) and luteinizing hormone-LH (26.4 ± 37.3 mIU/mL vs. 9.9 ± 14.5 mIU/mL) and lower levels of progesterone (5.2 ± 9.2 ng/mL vs. 10.4 ± 13.4 ng/mL). There was no significant difference in the levels of FT3, FT4, thyroid stimulating hormone, prolactin, follicle-stimulating hormone (FSH), progesterone, testosterone, or androstenedione levels. The WWE-I had 8.5 times higher risk (95% confidence interval 1.2-59.9) of abnormal LH/FSH ratio. WWE who were on antiepileptic drugs (AEDs) (compared to WWE who were not on AEDs) had higher risk of elevated LH/FSH ratio.

Conclusion:

The hormone profile of WWE-I is significantly different from that of WWE-F. These variations need to be interpreted with caution as a causal relationship to epilepsy or use of antiepileptic drugs need to be established through further studies.

Design and methodology of a community-based cluster-randomized controlled trial for dietary behaviour change in rural Kerala

Background

Interventions targeting lifestyle-related risk factors and non-communicable diseases have contributed to the mainstream knowledge necessary for action. However, there are gaps in how this knowledge can be translated for practical day-to-day use in complex multicultural settings like that in India. Here, we describe the design of the Behavioural Intervention for Diet study, which was developed as a community-based intervention to change dietary behaviour among middle-income households in rural Kerala.

Methods

This was a cluster-randomized controlled trial to assess the effectiveness of a sequential stage-matched intervention to bring about dietary behaviour change by targeting the procurement and consumption of five dietary components: fruits, vegetables, salt, sugar, and oil. Following a step-wise process of pairing and exclusion of outliers, six out of 22 administrative units in the northern part of Trivandrum district, Kerala state were randomly selected and allocated to intervention or control arms. Trained community volunteers carried out the data collection and intervention delivery. An innovative tool was developed to assess household readiness-to-change, and a household measurement kit and easy formulas were introduced to facilitate the practical side of behaviour change. The 1-year intervention included a household component with sequential stage-matched intervention strategies at 0, 6, and 12 months along with counselling sessions, telephonic reminders, and home visits and a community component with general awareness sessions in the intervention arm. Households in the control arm received information on recommended levels of intake of the five dietary components and general dietary information leaflets.

Discussion

Formative research provided the knowledge to contextualise the design of the study in accordance with socio-cultural aspects, felt needs of the community, and the ground realities associated with existing dietary procurement, preparation, and consumption patterns. The study also addressed two key issues, namely the central role of the household as the decision unit and the long-term sustainability through the use of existing local and administrative networks and community volunteers.

The adherence to medications in diabetic patients in rural Kerala, India

We conducted a study to determine medications adherence and factors associated with poor adherence in community-dwelling adults with diabetes in southern India. A cross-sectional survey was conducted among 346 diabetes patients selected using multistage cluster sampling. The 8-item Morisky Medication Adherence Scale was used to collect information on adherence. Prevalence of poor adherence was 74% (95% confidence interval = 69.2-78.3). Multiple regression analysis showed that patients using oral hypoglycemic agents, who had lower per capita monthly expenditure, those with irregular blood sugar monitoring, who received limited diabetes management instructions from health professionals, who resorted to only symptomatic management, and those who did not receive family member's help to remember medications were more likely to report poor adherence compared with their counterparts. Interventions for patients using oral hypoglycemic agents, with lower expenditure, with irregular blood sugar monitoring, and which focus on better education and enhanced family support, are likely to enhance adherence in this population.

Smoking cessation among diabetes patients: results of a pilot randomized controlled trial in Kerala, India

BACKGROUND

India has the second largest diabetic population (61 million) and tobacco users (275 million) in the world. Data on smoking cessation among diabetic patients are limited in low and middle income countries. The objective of the study was to document the effectiveness of diabetic specific smoking cessation counseling by a non-doctor health professional in addition to a cessation advice to quit, delivered by doctors.

METHODS

In our parallel-group randomized controlled trial, we selected 224 adult diabetes patients aged 18 years or older who smoked in the last month, from two diabetes clinics in South India. Using a computer generated random sequence with block size four; the patients were randomized equally into intervention-1 and intervention-2 groups. Patients in both groups were asked and advised to quit smoking by a doctor and distributed diabetes specific education materials. The intervention-2 group received an additional diabetes specific 30 minutes counseling session using the 5As (Ask, Advise, Assess, Assist and Arrange), and 5 Rs (Relevance, Risks, Rewards, Roadblocks and Repetition) from a non-doctor health professional. Follow up data were available for 87.5% of patients at six months. The Quit Tobacco International Project is supported by a grant from the Fogarty International Centre of the US National Institutes of Health (RO1TW005969-01).The primary outcomes were quit rate (seven day smoking abstinence) and harm reduction (reduction of the number of cigarettes / bidis smoked per day > 50% of baseline use) at six months.

RESULTS

In the intention to treat analysis, the odds for quitting was 8.4 [95% confidence interval (CI): 4.1-17.1] for intervention-2 group compared to intervention-1 group. Even among high level smokers the odds of quitting was similar. The odds of harm reduction was 1.9 (CI: 0.8-4.1) for intervention-2 group compared to intervention-1 group.

CONCLUSIONS

The value addition of culturally sensitive diabetic specific cessation counseling sessions delivered by non-doctor health professional was an impressive and efficacious way of preventing smoking related diabetic complications.

Risk factors of post-traumatic stress disorder in tsunami survivors of Kanyakumari District, Tamil Nadu, India

CONTEXT

In this study, we assessed the relation of possible risk factors with post-traumatic stress disorder (PTSD) in the survivors of December 2004 tsunami in Kanyakumari district.

MATERIALS AND METHODS

We identified cases (n=158) and controls (n=141) by screening a random sample of 485 tsunami survivors from June 2005 to October 2005 using a validated tool, "Impact of events scale-revised (IES-R)," for symptoms suggestive of PTSD. Subjects whose score was equal to or above the 70(th) percentile (total score 48) were cases and those who had score below or equal to 30(th) percentile (total score 33) were controls. Analysis was done using statistical package for the social sciences to find the risk factors of PTSD among various pre-disaster, within-disaster and post-disaster factors.

RESULTS

Multivariate analysis showed that PTSD was related to female gender [odds ratio (OR) 6.35, 95% confidence interval (CI) 3.26-12.39], age 40 years and above (OR 2.38, 95% CI 1.23-4.63), injury to self (OR 2.97, 95% CI 1.55-5.67), injury to family members (OR 2.09, 95% CI 1.05-4.15), residence in urban area (area of maximum destruction) (OR 3.37, 95% CI 1.35-8.41) and death of close relatives (OR 3.83, 95% CI 1.91-7.68). Absence of fear of recurrence of tsunami (OR 0.32, 95% CI 0.17-0.60), satisfaction of services received (OR 0.57, 95% CI 0.36-0.92) and counseling services received more than three times (OR 0.45, 95% CI 0.26-0.78) had protective effect against PTSD.

CONCLUSIONS

There is an association of pre-disaster, within-disaster and post-disaster factors with PTSD, which demands specific interventions at all phases of disaster, with a special focus on vulnerable groups.

Incidence of hypertension and its risk factors in rural Kerala, India: a community-based cohort study

OBJECTIVES

To investigate the incidence of hypertension and its risk factors in Kerala, India where the epidemiological transition is more advanced than elsewhere in India.

STUDY DESIGN

Prospective cohort study.

METHODS

A sample of 297 individuals (aged 15-64 years) in rural Kerala, India, who were free of hypertension at study enrolment, were followed-up from 2003 to 2010. At enrolment, demographic characteristics and behavioural risk factors were determined by interview, and the participants underwent physical (blood pressure, height, weight and waist circumference) and biochemical examinations (fasting plasma glucose and serum lipids). At follow-up, blood pressure readings were repeated using the original tool following the same protocol.

RESULTS

Nearly one-quarter (23.6%) of the sample developed hypertension over a mean follow-up period of 7.1 (standard deviation 0.2) years. Age ≥35 years [relative risk (RR) 4.00, 95% confidence interval (CI) 2.37-6.03], current smoking [RR 1.99, 95% CI 1.14-2.97, population-attributable risk percent (PAR%) 13.3%], high-normal blood pressure (RR 3.53 vs optimal blood pressure, 95% CI 2.17-5.28, PAR% 44.0%) and central obesity (RR 2.45, 95% CI 1.45-3.70, PAR% 40.4%) were significantly associated with incident hypertension. Collectively, current smoking, high-normal blood pressure and central obesity accounted for 70.1% of all new cases of hypertension. Awareness, treatment and control rates of incident hypertension were 42.9%, 22.9% and 11.4%, respectively.

CONCLUSIONS

This rural sample showed a high incidence of hypertension. This underscores the need for primary prevention of hypertension through lifestyle modification strategies targeting individuals with high-normal blood pressure, central obesity and current smoking. The healthcare system needs to improve the level of awareness, treatment and control of hypertension in this population.

Knowledge and practice profile of obstetricians regarding epilepsy in women in Kerala state, India

Purpose:

To assess the knowledge of obstetricians about concerns of women with epilepsy.

Materials and Methods:

We surveyed 97 obstetricians (teaching hospitals—43, private hospitals—32, and community health centers–21) using knowledge of women's issues and epilepsy (KOWIE) questionnaire II with additional questions.

Results:

The mean duration of practice of the surveyed obstetricians was 12.4 ± 10.7 years and 94% were female doctors. Most of them were well informed about the teratogenic effects of AEDs (91%), need to continue antiepileptic drugs (AEDs) during pregnancy (95%), and the role of folic acid and vitamin K during pregnancy (95%). They agreed AEDs decrease the efficacy of oral contraception and it was safe for the woman to breast-feed the baby while on AEDs. Only 1/3^rd of them knew that steroid hormones could alter seizure threshold or that AEDs could predispose to osteomalacia. Fewer doctors knew that WWE could have increased sexual dysfunction (29.9%) or infertility (26.8%). The knowledge did not vary according to years of practice or practice settings.

Conclusions:

Obstetricians were well informed about the fetal complications of antenatal AED exposure, but were under informed of other complications such as osteomalacia, sexual dysfunction, and infertility.

Clinical, electrophysiologic, and histopathologic profile, and outcome in idiopathic inflammatory myositis: An analysis of 68 cases

Objectives:

To study the electroclinical and histopathologic profile of idiopathic inflammatory myositis (IIM) with reference to prognosis and survival rate.

Materials and Methods:

Diagnosis of IIM was based on the Bohan and Peter criteria. Patients who improved and those whose condition worsened or who expired due to IIM per se at last follow-up were classified to have favorable and poor outcomes, respectively. Fisher’s exact test was used for univariate analysis of prognostic factors.

Results:

The study cohort consisted of consecutive 68 patients with IIM. The mean age at diagnosis was 36.5 years and females constituted 71%. Of these patients, 62% had definite IIM, 49% had polymyositis, 20% had dermatomyositis, and 29% had overlap syndrome. The mean follow-up period was 5.4 years. Prednisolone alone was used in 55 (80%), and azathioprine (1–3 mg/kg/day) alone in 12 (17.6%) as the initial treatment. Relapse of IIM with drug withdrawal was seen in 15 patients (22%); 70% had favorable outcome and 16% had expired. The treatment delay of ≤6 months (P = 0.001), absence of cardiac or lung involvement (P < 0.001), and positive biopsy (P = 0.033) were predictive of a favorable prognosis in the univariate analysis. In multivariate analysis, only the duration of illness of ≤6 months (P = 0.008) and the absence of cardiac or lung involvement (P = 0.001) predicted the favorable outcome at last follow-up. Cumulative survival rate was 95% at 1 year, 86% at the 5th year, and 80% at the 10th year.

Conclusions:

Approximately, two-thirds of the patients showed good electroclinical and histopathologic correlations and an equal number improved with treatment. The treatment delay (≥6 months), presence of cardiac or pulmonary involvements, and negative muscle biopsy are bad prognostic factors.

The ASPIRE approach for TIA risk stratification

BACKGROUND

The risk of stroke after transient ischemic attack (TIA) is elevated in the days to weeks after TIA. A variety of prediction rules to predict stroke risk have been suggested. In Alberta a triage algorithm to facilitate urgent access based on risk level was agreed upon for the province. Patients with ABCD2 score ≥ 4, or motor or speech symptoms lasting greater than five minutes, or with atrial fibrillation were considered high risk (the ASPIRE approach). We assessed the ability of the ASPIRE approach to identify patients at risk for stroke.

METHODS

We retrospectively reviewed charts from 573 consecutive patients diagnosed with TIA in Foothills Hospital emergency room from 2002 through 2005. We recorded clinical and event details and identified the risk of stroke at three months.

RESULTS

Among 573 patients the 90-day risk of stroke was 4.7% (95% CI 3.0%, 6.4%). 78% of the patients were identified as high risk using this approach. In patients defined as high risk on the ASPIRE approach there was a 6.3% (95% CI 4.2%, 8.9%) risk of stroke. In patients defined as low risk using the ASPIRE approach there were no recurrent strokes (100% negative predictive value). In contrast, two patients with low ABCD2 scores (ABCD2 score < 4) suffered recurrent strokes.

CONCLUSION

The ASPIRE approach has a perfect negative predictive value in the population in predicting stroke. However, this high sensitivity comes at a cost of identifying most patients as high risk.

Gender-specific psychosocial outcome for women with epilepsy

The objective of the study described here was to compare gender-specific differences of the personal impact of juvenile myoclonic epilepsy (JME) and temporal lobe epilepsy (TLE). We interviewed consecutive men and women with JME or TLE attending a tertiary epilepsy center to characterize their clinical and psychological profiles and details of employment and marriage. We recruited 150 persons with JME (74 males) and 150 with TLE (80 males). There were no gender-specific differences between men and women with respect to age at onset or semiology or frequency of seizures. Antiepileptic drug usage was comparable for both sexes except that fewer women with JME were prescribed valproate. Comorbidities, lower employment, and higher anxiety state were more frequent for women with epilepsy than for men with epilepsy. Females had more difficulty finding life partners compared with males. Women with epilepsy were at increased risk of divorce. Women with epilepsy have more problems with, marriage, mood, and employment as compared with men, even when the clinical profiles of their epilepsy syndromes are comparable.

Awareness, attitude and perceived barriers regarding implementation of the Cigarettes and Other Tobacco Products Act in Assam, India

BACKGROUND

Tobacco use is a major public health problem in India. The Cigarettes and Other Tobacco Products Act (COTPA) was developed to curb this epidemic. Because no study has been conducted on the awareness, attitude and perceived barriers regarding the implementation of COTPA, this study was undertaken.

MATERIALS AND METHODS

A community-based cross-sectional survey was conducted among 300 adults (mean age 41 years, 52% men) selected by cluster sampling method from Guwahati Municipal Corporation. Information on awareness, attitude and their predictors and barriers for implementation was collected using a pretested, structured interview schedule. Multivariate analysis was done using SPSS.

RESULTS

Adults older than 50 years were 3 times (odds ratio [OR] 3.02, 95% CI 1.44-6.31) and those with more than 10 years of schooling were 4 times (OR 3.60, 95% CI 1.70-7.70) more likely to have good awareness of COTPA compared with their counter parts. Those belonging to the middle socioeconomic status (SES) were 3 times (OR 3.36, 95% CI 1.13-10.01), those who reported secondhand smoking harmful were 3 times (OR 3.32, 95% CI 1.45-7.62), and those with more than 10 years of schooling were 3 times (OR 2.92, 95% CI 1.01-8.45) more likely to have positive attitude toward COTPA compared with their counterparts. Lack of complete information and awareness of the Act, public opposition, cultural acceptance of tobacco use, lack of political support, and less priority for tobacco control were reported as barriers for COTPA implementation.

CONCLUSION

Efforts should be made to increase the awareness of COTPA focusing on younger population, less educated, and those belonging to the low SES.

GROWTH-RETARDING EFFECT OF CORN IN NICOTINIC ACID-LOW RATIONS AND ITS COUNTERACTION BY TRYPTOPHANE

Either 50 mg 1(-)tryptophane or 1.0 mg nicotinic acid per 100 gms of ration completely counteracts the growth retardation caused by the inclusion of 40 per cent. corn grits in a low protein ration. A possible explanation of this observation is discussed.

Role of diffusion tensor imaging in differentiating subtypes of meningiomas

PURPOSE

Meningiomas are the most common extraaxial intracranial type of tumor, and their management and prognosis depend on their grade and histology. Diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) are two new imaging techniques that have proved helpful in elucidating the microarchitecture of brain tumors. The aim of the present study was to assess the role of diffusion and diffusion tensor metrics in the identification and classification of meningioma grades and subtypes.

METHODS AND MATERIALS

A total of 21 consecutive patients with meningioma were included in this retrospective study, of whom 16 had benign meningiomas (three fibroblastic, 11 transitional/mixed, two meningothelial) and five had atypical meningiomas. Tumor mean diffusivity (Dav), fractional anisotropy (FA), linear anisotropy (CL), planar anisotropy (CP), spherical anisotropy (CS) and eigenvalues (e1, e2, e3) were measured in all cases, and differences in diffusion tensor metrics between atypical, fibroblastic and other benign (transitional, meningothelial) meningiomas were statistically analyzed using the Mann-Whitney test.

RESULTS

No statistically significant differences were found among the mean Dav values for atypical, fibroblastic and other benign meningiomas. Both atypical and fibroblastic meningiomas showed significantly higher mean FA values and lower mean CS values compared with other meningiomas (P<0.01), but no statistically significant difference in these values between each other. Atypical meningiomas showed higher CL values compared with fibroblastic and other benign meningiomas but, again, the difference was not statistically significant. Both atypical and fibroblastic meningiomas showed statistically significantly higher CP values and lower e3 values compared with transitional meningiomas (P<0.01).

CONCLUSION

These results suggest that diffusion tensor metrics may be helpful in the differentiation of atypical, fibroblastic and other benign meningiomas.

Risk factor profile for chronic non-communicable diseases: results of a community-based study in Kerala, India

BACKGROUND & OBJECTIVES

Kerala State is a harbinger of what will happen in future to the rest of India in chronic non-communicable diseases (NCD). We assessed: (i) the burden of NCD risk factors; (ii) estimated the relations of behavioural risk factors to socio-demographic correlates, anthropometric risk factors with behavioural risk factors; (iii) evaluated if socio-demographic, behavioural and anthropometric risk factors predicted biochemical risk factors; and (iv) estimated awareness, treatment and adequacy of control of hypertension and diabetes, in Kerala state.

METHODS

A total of 7449 individuals (51% women) stratified by age group, sex and place of residence were selected and information on behavioural risk factors; tobacco use, diet, physical activity, alcohol use, measured anthropometry, blood pressure was collected. Fasting blood samples were analysed for blood glucose, total cholesterol, high density lipoprotein cholesterol and triglycerides in a sample subset.Using multiple logistic regression models the associations between socio-demographic and anthropometric variables with biochemical risk factors were estimated.

RESULTS

The burden of NCD risk factors was high in our sample. Prevalence of behavioural and each of the biochemical risk factors increased with age, adjusting for other factors including sex and the place of residence. The odds ratios relating anthropometric variables to biochemical variables were modest, suggesting that anthropometric variables may not be useful surrogates for biochemical risk factors for population screening purposes.

INTERPRETATION & CONCLUSIONS

In this large study of community-based sample in Kerala, high burden of NCD risk factors was observed, comparable to that in the United States. These data may serve to propel multisectoral efforts to lower the community burden of NCD risk factors in India in general, and in Kerala, in particular.
