Family-led rehabilitation after stroke in India (ATTEND): a randomised controlled trial

BACKGROUND

Most people with stroke in India have no access to organised rehabilitation services. The effectiveness of training family members to provide stroke rehabilitation is uncertain. Our primary objective was to determine whether family-led stroke rehabilitation, initiated in hospital and continued at home, would be superior to usual care in a low-resource setting.

METHODS

The Family-led Rehabilitation after Stroke in India (ATTEND) trial was a prospectively randomised open trial with blinded endpoint done across 14 hospitals in India. Patients aged 18 years or older who had had a stroke within the past month, had residual disability and reasonable expectation of survival, and who had an informal family-nominated caregiver were randomly assigned to intervention or usual care by site coordinators using a secure web-based system with minimisation by site and stroke severity. The family members of participants in the intervention group received additional structured rehabilitation training-including information provision, joint goal setting, carer training, and task-specific training-that was started in hospital and continued at home for up to 2 months. The primary outcome was death or dependency at 6 months, defined by scores 3-6 on the modified Rankin scale (range, 0 [no symptoms] to 6 [death]) as assessed by masked observers. Analyses were by intention to treat. This trial is registered with Clinical Trials Registry-India (CTRI/2013/04/003557), Australian New Zealand Clinical Trials Registry (ACTRN12613000078752), and Universal Trial Number (U1111-1138-6707).

FINDINGS

Between Jan 13, 2014, and Feb 12, 2016, 1250 patients were randomly assigned to intervention (n=623) or control (n=627) groups. 33 patients were lost to follow-up (14 intervention, 19 control) and five patients withdrew (two intervention, three control). At 6 months, 285 (47%) of 607 patients in the intervention group and 287 (47%) of 605 controls were dead or dependent (odds ratio 0·98, 95% CI 0·78-1·23, p=0·87). 72 (12%) patients in the intervention group and 86 (14%) in the control group died (p=0·27), and we observed no difference in rehospitalisation (89 [14%]patients in the intervention group vs 82 [13%] in the control group; p=0·56). We also found no difference in total non-fatal events (112 events in 82 [13%] intervention patients vs 110 events in 79 [13%] control patients; p=0·80).

INTERPRETATION

Although task shifting is an attractive solution for health-care sustainability, our results do not support investment in new stroke rehabilitation services that shift tasks to family caregivers, unless new evidence emerges. A future avenue of research should be to investigate the effects of task shifting to health-care assistants or team-based community care.

Quantitative characteristics of the foot-and-mouth disease carrier state under natural conditions in India

The goal of this study was to characterize the properties and duration of the foot-and-mouth disease (FMD) carrier state and associated serological responses subsequent to vaccination and naturally occurring infection at two farms in northern India. Despite previous vaccination of cattle in these herds, clinical signs of FMD occurred in October 2013 within a subset of animals at the farms containing juvenile-yearling heifers and steers (Farm A) and adult dairy cattle (Farm B). Subsequent to the outbreak, FMD virus (FMDV) asymptomatic carriers were identified in both herds by seroreactivity to FMDV non-structural proteins and detection of FMDV genomic RNA in oropharyngeal fluid. Carriers' seroreactivity and FMDV genome detection status were subsequently monitored monthly for 23 months. The mean extinction time of the carrier state was 13.1 ± 0.2 months, with extinction having occurred significantly faster amongst adult dairy cattle at Farm B compared to younger animals at Farm A. The rate of decrease in the proportion of carrier animals was calculated to be 0.07 per month. Seroprevalence against FMDV non-structural proteins decreased over the course of the study period, but was found to increase transiently following repeated vaccinations. These data provide novel insights into viral and host factors associated with the FMDV carrier state under natural conditions. The findings reported herein may be relevant to field veterinarians and governmental regulatory entities engaged in FMD response and control measures.

An Assessment of the Primary Payer Variable among Breast and Colorectal Cancer Cases in the Massachusetts Cancer Registry, 2005-2009

The Massachusetts Cancer Registry (MCR) reviewed the medical charts of 5,348 randomly selected breast and colorectal cancer cases diagnosed from 2005 to 2009. The purpose of this study was to assess the reliability of primary payer at diagnosis in the MCR database and to examine primary payer and the first course of treatment of individual cancer patients. For the first period (2005-2006), private insurance (72.6% agreement) and Medicare (84.3% agreement) indicated strong agreement with kappa values of 0.62 and 0.72, respectively. Agreement for the later period was again stronger in the private insurance and Medicare categories (kappa= 0.63 and 0.74, respectively).

Fibroblast growth factor-23 levels in maintenance hemodialysis patients in India

Fibroblast growth factor-23 (FGF-23) levels start rising early in patients with chronic kidney disease and is implicated in cardiovascular and overall mortality of hemodialysis patients. We conducted a prospective observational cohort study in stable dialysis patients looking into the levels of FGF-23 in hemodialysis patients and its association with various demographic and biochemical variables and mortality. A total of 91 patients were enrolled in the study. The mean FGF-23 levels were very high (1152.7 pg/ml). FGF-23 levels were significantly associated with serum phosphorus and parathyroid hormone (PTH) levels in univariate and multivariate analysis. No significant association between FGF-23 and cardiovascular comorbidities and overall mortality was seen. FGF-23 levels rise exponentially in maintenance hemodialysis patients. There is a strong association between FGF-23 and phosphorus and PTH levels. No association between FGF-23 and mortality was noted in our patients.

What a difference a day makes: same-day vs. 2-day sputum smear microscopy for diagnosing tuberculosis

Setting: Nine district-level microscopy centres in Assam and Tripura, India. Objective: Same-day sputum microscopy is now recommended for tuberculosis (TB) diagnosis. We compared this method against the conventional 2-day approach in routine programmatic settings. Methods: During October-December 2012, all adult presumptive TB patients were requested to provide three sputum samples (one at the initial visit, the second 1 h after the first sample, and the third the next morning) for examination by Ziehl-Neelsen smear microscopy. Detection of acid-fast bacilli with any sample was diagnostic. The first and second spot sample comprised the same-day approach, and the first spot sample and next-day sample comprised the 2-day approach. Results: Of 2168 presumptive TB patients, 403 (18.6%) were smear-positive according to the same-day method compared to 427 (19.7%) by the 2-day method (McNemar's test, P < 0.001). Of the total 429 TB patients, 26 (6.1%) were missed by the same-day method and 2 (0.5%) by the 2-day method. Conclusion: Same-day specimen collection for microscopy missed more TB than 2-day collection. In India, missing cases by using same-day microscopy would translate into a considerable absolute number, hindering TB control efforts. We question the indiscriminate switch to same-day diagnosis in settings where patients reliably return for testing the next day.

Isolation and characterization of foot-and-mouth disease virus from Odisha, India

Foot-and-mouth disease (FMD) is a highly contagious and rapidly transmissible disease of cloven footed animals. Emergence of genetically divergent strains of FMD virus (FMDV) is a major concern globally. FMD is endemic in India and three serotypes (O, A and Asia 1) prevail. The study was undertaken to characterize the isolates from the state of Odisha, India both genetically and antigenically. FMDV was detected in 7 of the 17 clinical samples collected from FMD affected/suspected animals, in which serotype O and A were found in three and four samples, respectively. Serotype O field isolates clustered in an unnamed group (designated here as Eastern cluster) circulating mostly in the Eastern region of the country and had 10-12.7% divergence from the Ind2001 lineage circulating predominantly throughout the country. The serotype A isolates sequenced in this study was grouped within VP3⁵⁹-deletion group of genotype 18, precisely in clade 18c, having high genetic homology to the virus circulating in the neighboring states, suggesting interstate movement. Both the serotype O and A isolates showed good antigenic relationship value with the respective vaccine strains currently used in the country.

Atypical magnetic resonance imaging features in subacute sclerosing panencephalitis

Objectives:

Subacute sclerosing panencephalitis (SSPE) is rare chronic, progressive encephalitis that affects primarily children and young adults, caused by a persistent infection with measles virus. No cure for SSPE exists, but the condition can be managed by medication if treatment is started at an early stage.

Methods and Results:

Heterogeneity of imaging findings in SSPE is not very uncommon. But pial and gyral enhancements are very rarely noticed. Significant asymmetric onset as well as pial-gyral enhancements is not reported. Herein we present a case of 16 years adolescent of SSPE having remarkable asymmetric pial-gyral enhancements, which were misinterpreted as tubercular infection.

Conclusion:

Early diagnosis and treatment is encouraging in SSPE, although it is not curable with current therapy. Clinico-radiological and electrophysiological correlation is very important in diagnosis of SSPE, more gravely in patients having atypical image findings as in our index case.

Oxygen isotope in archaeological bioapatites from India: Implications to climate change and decline of Bronze Age Harappan civilization

The antiquity and decline of the Bronze Age Harappan civilization in the Indus-Ghaggar-Hakra river valleys is an enigma in archaeology. Weakening of the monsoon after ~5 ka BP (and droughts throughout the Asia) is a strong contender for the Harappan collapse, although controversy exists about the synchroneity of climate change and collapse of civilization. One reason for this controversy is lack of a continuous record of cultural levels and palaeomonsoon change in close proximity. We report a high resolution oxygen isotope (δ¹⁸O) record of animal teeth-bone phosphates from an archaeological trench itself at Bhirrana, NW India, preserving all cultural levels of this civilization. Bhirrana was part of a high concentration of settlements along the dried up mythical Vedic river valley ‘Saraswati’, an extension of Ghaggar river in the Thar desert. Isotope and archaeological data suggest that the pre-Harappans started inhabiting this area along the mighty Ghaggar-Hakra rivers fed by intensified monsoon from 9 to 7 ka BP. The monsoon monotonically declined after 7 ka yet the settlements continued to survive from early to mature Harappan time. Our study suggests that other cause like change in subsistence strategy by shifting crop patterns rather than climate change was responsible for Harappan collapse.

Hereditary inclusion body myopathy: A myopathy with unique topography of weakness, yet frequently misdiagnosed: Case series and review of literature

Background:

Hereditary inclusion body myopathy (HIBM) continues to be underrecognized clinically despite a characteristic topography of weakness with total sparing of quadriceps muscles and patient being wheelchair bound. We report seven patients of HIBM from four families in North India.

Methods and Results:

Seven patients from four different families were diagnosed to have HIBM. There was no consanguinity in any of the families. While one patient had two affected siblings, another had one affected siblings and the family history was noncontributory in two patients. Two of the siblings were available for examination and confirmed clinically to be suffering from HIBM. Among the seven patients, only one was still ambulatory at the time of diagnosis.

Discussion:

This is the first case report of occurrence of HIBM in North Indian population. Despite its unique clinical presentation, HIBM is frequently misdiagnosed resulting in unnecessary diagnostic and therapeutic interventions. A high index of suspicion of this rare myopathy along with proper clinical examination may go a long way in accurate prognostication and management of these patients.

Supraclavicular brachial plexus block using ropivacaine alone or combined with dexmedetomidine for upper limb surgery: A prospective, randomized, double-blinded, comparative study

BACKGROUND

Dexmedetomidine is a new α-2 receptor agonist with analgesic and sedative properties. We used dexmedetomidine along with ropivacaine for supraclavicular brachial plexus block.

METHODS

Eighty ASA grade I-II patients, 18-60 years old, scheduled for elective upper limb orthopaedic surgery under supraclavicular brachial plexus block, were included in this prospective study. The patients were randomly assigned to group R (ropivacaine alone) and group RD (ropivacaine and dexmedetomidine) (40 patients in each group). Group R received ropivacaine 0.50% (30 cc)+placebo and group RD received ropivacaine 0.50% (30 cc)+dexmedetomidine 1 μg/kg. Primary outcome measure was duration of analgesia. Secondary measures were onset and duration of sensory blockade, pain scores, onset and duration of motor blockade, and evidence of any adverse drug reactions.

RESULTS

There was no significant difference hemodynamic parameter during intra-operative period. Group RD showed a statistically significant shorter time to onset of sensory blockade (10.75±2.71 vs. 16.75±2.96 min, P=.003), longer sensory block duration (379.40±55.09 vs. 211.60±47.88 min, P=.002), shorter onset time to motor blockade (14.35±2.58 vs. 20.25±4.13 min, P=.003), longer motor block duration (312.0±49.91 vs. 184.7±36.76 min, P=.002), longer duration of postoperative analgesia (413.73±89.92 vs. 197.35±28.67 min, P=.002). Three patients in the group RD developed somnolence. (P=.04).

CONCLUSION

Dexmedetomidine along with ropivacaine decreases the onset of motor and sensory block and increases the duration of sensory and motor block in supraclavicular brachial plexus block.
