RESUMO

Background Menopause is a physiological state that occurs in all women and refers to the halt of the reproductive phase. The cessation of the reproductive phase occurs through various stages and presents different symptoms such as hot flashes, night sweats, insomnia, anxiety, depression, and irritability. Such pre- and post-menopausal symptoms may affect the daily activities and production capacities of women, impacting the quality of life (QoL) of women. Hormone replacement therapy (HRT) is primarily used to manage menopausal symptoms. However, various side effects have been reported related to HRT. Therefore, women are choosing alternative medicine such as Ayurveda that can benefit them with less or no adverse effects. Shatavari (Asparagus racemosus) is known in Ayurveda as an effective medicinal plant source for various women's health remedies since ancient times. This study aimed to evaluate the safety and efficacy of the Ayurvedic Shatavari formulation on menopausal symptoms compared to the placebo. Methodology This is a randomized, double-blinded, multicenter, placebo-controlled, clinical study. Altogether, 70 patients were randomized to two groups, i.e., the test group (active group) and the placebo group (microcrystalline cellulose), with 35 participants in each group. Results The study outcomes showed a positive and significant effect of the active test ingredient over the placebo in terms of reduction in hot flashes, night sweats, insomnia, anxiety, nervousness, vaginal dryness, and loss of libido. The Utian QoL improved significantly in the test group compared to the placebo group. No significant adverse events were recorded in the test group, suggesting the safety of this formulation. Conclusions The test compound could be a safe alternative to modern drugs. The findings of this study support the traditional use of Shatavari. Further clinical and pharmacological studies with longer duration and larger and more diverse sample sizes are required to understand the generalized effect of Shatavari root extract in menopausal women.

RESUMO

Increases in protein kinase C (PKC) are associated with diminished cardiac function, but the contribution of downstream myofilament phosphorylation is debated in human and animal models of heart failure. The current experiments evaluated PKC isoform expression, downstream cardiac troponin I (cTnI) S44 phosphorylation (p-S44), and contractile function in failing (F) human myocardium, and in rat models of cardiac dysfunction caused by pressure overload and aging. In F human myocardium, elevated PKCα expression and cTnI p-S44 developed before ventricular assist device implantation. Circulatory support partially reduced PKCα expression and cTnI p-S44 levels and improved cellular contractile function. Gene transfer of dominant negative PKCα (PKCαDN) into F human myocytes also improved contractile function and reduced cTnI p-S44. Heightened cTnI phosphorylation of the analogous residue accompanied reduced myocyte contractile function in a rat model of pressure overload and in aged Fischer 344 × Brown Norway F1 rats (≥26 mo). Together, these results indicate PKC-targeted cTnI p-S44 accompanies cardiac cellular dysfunction in human and animal models. Interfering with PKCα activity reduces downstream cTnI p-S44 levels and partially restores function, suggesting cTnI p-S44 may be a useful target to improve contractile function in the future.

RESUMO

OBJECTIVE: To prospectively correlate pain duration, red scrotal skin, ultrasound appearance of testis, and intraoperative testis color to future testis atrophy after acute testicular torsion. METHODS: Patients 2 months-18 years old with unilateral acute scrotum were consecutively enrolled in a National Institutes of Health transcutaneous near-infrared spectroscopy study, with a subgroup analysis of the true torsion group. Presence or absence of red scrotal skin, pain duration, testicular heterogeneity on preoperative ultrasound, and intraoperative testis color based on a novel visual chart 5 minutes after detorsion were recorded. All testes underwent orchiopexy regardless of appearance. Percent volume difference between normal and torsed testicles on follow-up ultrasound was compared between patients with and without risk factors. RESULTS: Thirty of 56 patients who had surgical detorsion underwent scrotal ultrasound at a mean of 117 days after surgery. A color of black or hemorrhagic 5 minutes after detorsion, pain duration >12 hours, and heterogeneous parenchyma on preoperative ultrasound were associated with significant testis volume loss in follow-up compared with normal testis. All patients with a black or hemorrhagic testis had >80% volume loss. Erythematous scrotal skin was not significantly associated with smaller affected testis volume in follow-up. CONCLUSION: Based on the high atrophy rate, orchiectomy can be considered for testes that are black or hemorrhagic 5 minutes after detorsion. Pain duration >12 hours and parenchymal heterogeneity on preoperative ultrasound were also associated with testis atrophy. Red scrotal skin was not a reliable predictor of atrophy and should not delay exploration.

RESUMO

OBJECTIVE: To assess the effect of implementing an emergency surgery track for testicular torsion transfers. We hypothesized that transferring children from other facilities diagnosed with torsion straight to the operating room (STOR) would decrease ischemia time, lower costs, and reduce testicular loss. STUDY DESIGN: Demographics, arrival to incision time, hospital cost in dollars, and testicular outcome (determined by testicular ultrasound) at follow-up were retrospectively compared in all patients transferred to our tertiary care children's hospital with a diagnosis of testicular torsion from 2012 to 2016. Clinical data for STOR and non-STOR patients were compared by Wilcoxon rank-sum, 2-tailed t test, or Fisher exact test as appropriate. RESULTS: Sixty-eight patients met inclusion criteria: 35 STOR and 33 non-STOR. Children taken STOR had a shorter median arrival to incision time (STOR: 54 minutes vs non-STOR: 94 minutes, P < .0001) and lower median total hospital costs (STOR: $3882 vs non-STOR: $4419, P < .0001). However, only 46.8% of STOR patients and 48.4% of non-STOR patients achieved surgery within 6 hours of symptom onset. Testicular salvage rates in STOR and non-STOR patients were not significantly different (STOR: 68.4% vs non-STOR: 36.8%, P = .1), but follow-up was poor. CONCLUSIONS: STOR decreased arrival to incision time and hospital cost but did not affect testicular loss. The bulk of ischemia time in torsion transfers occurred before arrival at our tertiary care center. Further interventions addressing delays in diagnosis and transfer are needed to truly improve testicular salvage rates in these patients.

RESUMO

BACKGROUND & OBJECTIVES: Kangaroo mother care (KMC - early continuous skin-to-skin contact between mother and infants) has been recommended as an alternative care for low birth weight infants. There is limited evidence in our country on KMC initiated at home. The present study was undertaken to study acceptability of KMC in different community settings. METHODS: A community-based pilot study was carried out at three sites in the States of Odisha, Gujarat and Maharashtra covering rural, urban and rural tribal population, respectively. Trained health workers provided IEC (information, education and communication) on KMC during antenatal period along with essential newborn care messages. These messages were reinforced during the postnatal period. Outcome measures were the proportion of women accepting KMC, duration of KMC/day and total number of days continuing KMC. Focus group discussions and in-depth interviews were also carried out. RESULTS: KMC was provided to 101 infants weighing 1500-2000 g; 57.4 per cent were preterm. Overall, 80.2 per cent mothers received health education on KMC during antenatal period, family members (68.3%) also attended KMC sessions along with pregnant women and 55.4 per cent of the women initiated KMC within 72 h of birth. KMC was provided on an average for five hours per day. Qualitative survey data indicated that the method was acceptable to mothers and family members; living in nuclear family, household work, twin pregnancy, hot weather, etc., were cited as reasons for not being able to practice KMC for a longer duration. INTERPRETATION & CONCLUSIONS: It was feasible to provide KMC using existing infrastructure, and the method was acceptable to most mothers of low birth infants.

RESUMO

Mortality and morbidity attributed to asthma remains to be the biggest nightmare worldwide. Hence, the study was aimed to compare the cardio metabolic risk factors as assessed by Body mass index (BMI), waist hip ratio (WHR), serum triacylglycerol and uric acid in well controlled and poorly controlled asthmatics and to correlate these parameters with the severity of asthma. A case control study was conducted on 90 subjects who were segregated into well controlled asthmatics (n = 30) and poorly controlled asthmatics (n = 30) who were diagnosed based on Global initiative for Asthma management guidelines and healthy volunteers (n = 30). Centrifuged fasting venous blood samples were used for biochemical analysis, pulmonary function test, BMI, and waist hip ratio (WHR) were measured. The statistical analysis was done using SPSS version 17. There was a significant increase in BMI, WHR, lipid profile, serum uric acid and decrease in forced expiratory volume (FEV1), forced vital capacity (FVC), and FEV1/FVC in poorly controlled asthmatics. There was a significant association between FEV1 and serum uric acid, BMI and Triacylgycerol in poorly controlled asthmatics. Poorly controlled asthmatics have greater risk of developing cardiometabolic problems. Serum uric acid can be used as one of the severity markers in asthma to assess cardio metabolic risk.

RESUMO

PURPOSE: A rapid test for testicular torsion in children may obviate the delay for testicular ultrasound. In this study we assessed testicular tissue percent oxygen saturation (%StO2) measured by transscrotal near infrared spectroscopy as a diagnostic test for pediatric testicular torsion. MATERIALS AND METHODS: This was a prospective comparison to a gold standard diagnostic test study that evaluated near infrared spectroscopy %StO2 readings to diagnose testicular torsion. The gold standard for torsion diagnosis was standard clinical care. From 2013 to 2015 males with acute scrotum for more than 1 month and who were less than 18 years old were recruited. Near infrared spectroscopy %StO2 readings were obtained for affected and unaffected testes. Near infrared spectroscopy Δ%StO2 was calculated as unaffected minus affected reading. The utility of near infrared spectroscopy Δ%StO2 to diagnose testis torsion was described with ROC curves. RESULTS: Of 154 eligible patients 121 had near infrared spectroscopy readings. Median near infrared spectroscopy Δ%StO2 in the 36 patients with torsion was 2.0 (IQR -4.2 to 9.8) vs -1.7 (IQR -8.7 to 2.0) in the 85 without torsion (p=0.004). AUC for near infrared spectroscopy as a diagnostic test was 0.66 (95% CI 0.55-0.78). Near infrared spectroscopy Δ%StO2 of 20 or greater had a positive predictive value of 100% and a sensitivity of 22.2%. Tanner stage 3-5 cases without scrotal edema or with pain for 12 hours or less had an AUC of 0.91 (95% CI 0.86-1.0) and 0.80 (95% CI 0.62-0.99), respectively. CONCLUSIONS: In all children near infrared spectroscopy readings had limited utility in diagnosing torsion. However, in Tanner 3-5 cases without scrotal edema or with pain 12 hours or less, near infrared spectroscopy discriminated well between torsion and nontorsion.

RESUMO

India has one of the highest rates of underweight burden, with signs of rising obesity. Coexistence of underweight and overweight persons is symptomatic of the "double burden of malnutrition." The present study throws new light on the "double burden of malnutrition" among Indian women in the age group 22-49 years. The analysis is based on a nationally representative household survey, India Human Development Survey. Our results indicate the continuing pattern of socioeconomic segregation of underweight and overweight/obese women, with a large concentration of underweight women among the low socioeconomic group and of overweight/obese women among the high socioeconomic group. Further, relative food prices of food items like cereals and vegetables are significantly associated with the risk of being underweight and overweight/obese. Additionally, we find notable rural/urban differences. The relationship between socioeconomic factors and the probability of being underweight and overweight/obese is stronger in urban than in rural areas. Given that the health implications of being underweight and overweight/obese are equally grim, provision of healthy food items at affordable prices and implementation of programs for preventive and curative care of plausible illnesses related to underweight and overweight/obese are imperative.

RESUMO

BACKGROUND: Vitamin D deficiency (<10ng/mL) and insufficiency (10-30ng/mL) may contribute to musculoskeletal symptoms observed in patients taking letrozole. This study was undertaken to assess the vitamin D status in breast cancer patients who received letrozole for >2months and to see the effects of vitamin D3 and calcium supplementation on them. METHODS: Eighty-two breast cancer patients were included. Baseline serum 25-hydroxy vitamin D concentrations were assayed and standard questionnaire was completed. They were given vitamin D3 and calcium supplementation (2000IU/1000 mg and 4000IU/1000mg) based on their baseline serum 25-hydroxy vitamin D concentration for 12weeks. RESULTS: Baseline serum 25-hydroxy vitamin D concentrations showed that 13.4% of patients were deficient and 73.2% of patients were insufficient in 25-hydroxy vitamin D. There was an increase in the concentrations of calcium, phosphorus and decrease in the concentrations of parathyroid hormone, alkaline phosphatase as the concentration of serum 25-hydroxy vitamin D increases. Patients who received letrozole for a longer duration had a low concentration of serum 25 (OH) vitamin D. Vitamin D3 and calcium supplementation increased the concentrations of calcium, phosphorous and decreased the concentrations of parathyroid hormone and alkaline phosphatase. Patients who had low serum 25-hydroxy vitamin D concentrations had more musculoskeletal symptoms which was improved following supplementation (9.14 vs 8.10 p=0.000). CONCLUSION: Vitamin D3 supplementation significantly improved serum 25-hydroxy vitamin D concentrations and decreased letrozole-induced arthralgia.

RESUMO

PURPOSE: The TWIST (Testicular Workup for Ischemia and Suspected Torsion) score uses urological history and physical examination to assess risk of testis torsion. Parameters include testis swelling (2 points), hard testis (2), absent cremasteric reflex (1), nausea/vomiting (1) and high riding testis (1). While TWIST has been validated when scored by urologists, its diagnostic accuracy among nonurological providers is unknown. We assessed the usefulness of the TWIST score when determined by nonurological nonphysician providers, mirroring emergency room evaluation of acute scrotal pain. MATERIALS AND METHODS: Children with unilateral acute scrotum were prospectively enrolled in a National Institutes of Health clinical trial. After undergoing basic history and physical examination training, emergency medical technicians calculated TWIST score and determined Tanner stage per pictorial diagram. Clinical torsion was confirmed by surgical exploration. All data were captured into REDCap™ and ROC curves were used to evaluate the diagnostic usefulness of TWIST. RESULTS: Of 128 patients (mean age 11.3 years) 44 (13.0 years) had torsion. TWIST score cutoff values of 0 and 6 derived from ROC analysis identified 31 high, 57 intermediate and 40 low risk cases (positive predictive value 93.5%, negative predictive value 100%). CONCLUSIONS: TWIST score assessed by nonurologists, such as emergency medical technicians, is accurate. Low risk patients do not require ultrasound to rule out torsion. High risk patients can proceed directly to surgery, with more than 50% avoiding ultrasound. In the future emergency medical technicians and/or emergency room triage personnel may be able to calculate TWIST score to guide radiological evaluation and immediate surgical intervention at initial assessment long before urological consultation.

RESUMO

Endogenous fluorescence has been proposed as a means of aiding the diagnosis of various malignancies. It has been suggested that erythrocytes may be the carriers of fluorophors that accumulate in cancer tissue and may be useful in the diagnosis and treatment of malignancies. Hence, the present study was designed to explore the spectrofluorimetric analysis of blood components as a marker for the analysis of mammary carcinoma treatment and also to bring about the protective effect of the drug Semecarpus anacardium on oxidative stress mediated damage of erythrocytes. Fluorescence spectra of the blood components were studied and also the level of lipid per oxides and antioxidant enzymes status in erythrocytes were determined in DMBA induced mammary carcinoma rats treated with Semecarpus anacardium Linn nut milk extract. Fluorescence emission spectroscopy of blood components are altered under cancer conditions and the drug effectively ameliorated these alterations in mammary carcinoma induced rats. The drug also effectively reduced the oxidative stress induced erythrocyte damage thereby restoring the erythrocytes antioxidant status. These results suggest that erythrocytes may be the carriers of fluorophors that accumulate in cancer tissue and hence acts as new biomarkers for the diagnosis and treatment.

RESUMO

Current attempts at tissue regeneration utilizing synthetic and decellularized biologic-based materials have typically been met in part by innate immune responses in the form of a robust inflammatory reaction at the site of implantation or grafting. This can ultimately lead to tissue fibrosis with direct negative impact on tissue growth, development, and function. In order to temper the innate inflammatory response, anti-inflammatory signals were incorporated through display on self-assembling peptide nanofibers to promote tissue healing and subsequent graft compliance throughout the regenerative process. Utilizing an established urinary bladder augmentation model, the highly pro-inflammatory biologic scaffold (decellularized small intestinal submucosa) was treated with anti-inflammatory peptide amphiphiles (AIF-PAs) or control peptide amphiphiles and used for augmentation. Significant regenerative advantages of the AIF-PAs were observed including potent angiogenic responses, limited tissue collagen accumulation, and the modulation of macrophage and neutrophil responses in regenerated bladder tissue. Upon further characterization, a reduction in the levels of M2 macrophages was observed, but not in M1 macrophages in control groups, while treatment groups exhibited decreased levels of M1 macrophages and stabilized levels of M2 macrophages. Pro-inflammatory cytokine production was decreased while anti-inflammatory cytokines were up-regulated in treatment groups. This resulted in far fewer incidences of tissue granuloma and bladder stone formation. Finally, functional urinary bladder testing revealed greater bladder compliance and similar capacities in groups treated with AIF-PAs. Data demonstrate that AIF-PAs can alleviate galvanic innate immune responses and provide a highly conducive regenerative milieu that may be applicable in a variety of clinical settings.

RESUMO

OBJECTIVE: Children with occult spinal dysraphism represent a wide spectrum of patients. Previous studies assessing urologic outcomes have in part been deficient due to the inability to appropriately categorize these patients and gather long-term follow-up data. In this study, a uniform set of patients that had occult spinal dysraphism with magnetic resonance imaging findings of a fatty filum terminale (FF) and/or low-lying cord (LLC) was identified. Utilizing long-term follow-up data, predictors for achieving urinary continence following tethered cord release (TCR) were determined. METHODS: A retrospective chart review of pediatric patients with a diagnosis of tethered cord who underwent TCR from 1995 to 2005 was performed. Analysis was limited to patients who had primary TCR by one of two neurosurgeons within our multidisciplinary spina bifida clinic, who had greater than 1-year follow-up, and who were old enough to have continence status assessed (age > 6 years unless definitively toilet trained earlier). Patients with other associated forms of spinal dysraphism (lipomyelomeningeocele, spinal lipomas, sacral agenesis), anorectal malformations, and genitourinary anomalies were excluded. Pre- and post-TCR urodynamics, radiographic studies, functional orthopedic status, and urologic outcomes were assessed. Urodynamic results were categorized by three blinded urologists into one of three urodynamic patterns: (1) normal, (2) indeterminate, and (3) high risk. RESULTS: A total of 147 patients with FF and/or LLC that underwent TCR were reviewed. 51 patients were excluded because of another associated spinal dysraphism (15/51 patients) or an anorectal/genitourinary anomaly (36/51 patients). Fifty-nine of the remaining 96 patients had adequate long-term follow-up data to be included in the study. 20 patients were asymptomatic at the time of TCR while 39 presented with orthopedic and/or urologic symptoms. The average age at surgery was 59.3 months (range 2-277 months) with an average follow-up of 7.0 years (range 1-16 years). At latest follow-up, 47 (80%) patients were continent while 12 (20%) were either incontinent or utilizing clean intermittent catheterization (CIC). Statistical analysis revealed that age of untethering, type of cutaneous lesion, level of conus, presence of hydronephrosis, and high-grade vesicoureteral reflux (VUR) were not independent predictors of continence. In patients with a cutaneous lesion who were asymptomatic, 19/20 obtained continence post-TCR (*p = 0.036). In patients who were old enough to assess continence pre-TCR, 14/25 patients were continent pre-TCR and 11/25 were incontinent. Of the 14 who were continent pre-TCR, all remained continent post-TCR (*p = 0.002). Of the 11 who were incontinent pre-TCR, five (45%) eventually became continent post-TCR. Assessment of urodynamic data revealed that neither pre- nor post-TCR urodynamics predicted continence status. CONCLUSION: Isolated cutaneous lesions and preoperative continence status are positive predictors for post-TCR continence. While pre- and post-TCR urodynamics do not predict continence status, their utility in preoperative work-up, monitoring for retethering, and long-term urologic follow-up requires further examination.

RESUMO

OBJECTIVE: Managing patients with multiple adrenal masses is technically challenging. We present our experience with minimally invasive partial adrenalectomy (PA) performed for synchronous multiple ipsilateral pheochromocytomas in a single setting. MATERIALS AND METHODS: We reviewed records of patients undergoing PA for pheochromocytoma at the National Cancer Institute between 1994 and 2010. Patients were included if multiple tumors were excised from the ipsilateral adrenal gland in the same operative setting. Perioperative, functional, and oncologic outcomes of PA for multiple pheochromocytomas are shown. RESULTS: Of 121 partial adrenalectomies performed, 10 procedures performed in eight patients for synchronous multiple ipsilateral pheochromocytomas were identified. All eight patients were symptomatic at presentation. The mean patient age was 30.6 years, median follow up was 12 months. The average surgical time was 228 minutes, average blood loss of 125 mL, and average number of tumors removed was 2.6 per adrenal. In total, 26 tumors were removed, 24 were pathologically confirmed pheochromocytomas, while two were adrenal cortical hyperplasia. After surgery, all patients had resolution of their symptoms, one patient required steroid replacement postoperatively. On postoperative imaging, one patient had evidence of ipsilateral adrenal nodule at the prior resection site 2 months postoperatively, which was consistent with incomplete resection. CONCLUSIONS: Minimally invasive surgical resection of synchronous multiple pheochromocytomas is feasible with acceptable perioperative, functional, and short-term oncologic outcomes.

RESUMO

PURPOSE: To investigate the effect of 2-deoxy-D-glucose (2-DG), an inhibitor of glucose transport and glycolysis, on glioblastoma and the normal brain tissue during combined treatment with hypofractionated radiotherapy. MATERIALS AND METHODS: Twenty patients with malignant gliomas (18 Glioblastoma Multiformae, 2 Anasplastic Astrocytoma grade III) following surgery were treated weekly (once) with 2-DG, (250 mg/kg body weight), followed by 5 Gy of radiation to the tumor bed per fraction for 7 weeks. Clinical evaluation, complete hemogram, and random blood sugar levels were carried out in each cycle. Follow-up computed tomography (CT)/magnetic resonance imaging (MRI) was done to evaluate radiation-induced changes. Kernofsky Performance scale (KPS) was recorded preoperatively; postoperatively, and post-therapy till the last follow-up. RESULTS: Twenty patients were recruited for this trail; 19 of them completed the treatment and 1 discontinued. The survival period ranged between 6 and 36 months after the treatment, with a median survival of 14 months. CT and MRI revealed significant tumor necrosis. Histological evidence from the tissue during reexploration confirms the hypothesis of protective effect of 2-DG on normal brain. KPS was above 80% in majority of the patients, 6 months after the surgery. CONCLUSION: Radiotherapy coupled with 2-DG enhances tumor necrosis selectively and significantly while the normal brain gets relatively protected. This has been reflected in our study both clinically by preservation of quality-of-life and pathologically by retaining the integrity of normal brain architecture.

RESUMO

Quaternary climatic oscillations caused changes in sea level that altered the size, number and degree of isolation of islands, particularly in land-bridge archipelagoes. Elucidating the demographic effects of these oscillations increases our understanding of the role of climate change in shaping evolutionary processes in archipelagoes. The Puerto Rican Bank (PRB) (Puerto Rico and the Eastern Islands, which comprise Vieques, Culebra, the Virgin Islands and associated islets) in the eastern Caribbean Sea periodically coalesced during glaciations and fragmented during interglacial periods of the quaternary. To explore population-level consequences of sea level changes, we studied the phylogeography of the frog Eleutherodactylus antillensis across the archipelago. We tested hypotheses encompassing vicariance and dispersal narratives by sequencing mtDNA (c. 552 bp) of 285 individuals from 58 localities, and four nuDNA introns (totalling c. 1633 bp) from 173 of these individuals. We found low support for a hypothesis of divergence of the Eastern Islands populations prior to the start of the penultimate interglacial c. 250 kya, and higher support for a hypothesis of colonization of the Eastern Islands from sources in eastern Puerto Rico during the penultimate and last glacial period, when a land bridge united the PRB. The Río Grande de Loíza Basin in eastern Puerto Rico delineates a phylogeographic break. Haplotypes shared between the PRB and St. Croix (an island c. 105 km south-east of this archipelago) likely represent human-mediated introductions. Our findings illustrate how varying degrees of connectivity and isolation influence the evolution of tropical island organisms.

RESUMO

Enamel renal syndrome is a very rare disorder associating amelogenesis imperfecta with nephrocalcinosis. It is known by various synonyms such as amelogenesis imperfecta nephrocalcinosis syndrome, MacGibbon syndrome, Lubinsky syndrome, and Lubinsky-MacGibbon syndrome. It is characterized by enamel agenesis and medullary nephrocalcinosis. This paper describes enamel renal syndrome in a female patient born in a consanguineous family.

RESUMO

Despite accelerated growth there is pervasive hunger, child undernutrition and mortality in India. Our analysis focuses on their determinants. Raising living standards alone will not reduce hunger and undernutrition. Reduction of rural/urban disparities, income inequality, consumer price stabilization, and mothers' literacy all have roles of varying importance in different nutrition indicators. Somewhat surprisingly, public distribution system (PDS) do not have a significant effect on any of them. Generally, child undernutrition and mortality rise with poverty. Our analysis confirms that media exposure triggers public action, and helps avert child undernutrition and mortality. Drastic reduction of economic inequality is in fact key to averting child mortality, conditional upon a drastic reordering of social and economic arrangements.

RESUMO

The objective of this analysis is mainly to construct an intuitive measure of the performance of the National Rural Employment Guarantee Scheme (NREGS) in India. The focus is on divergence between demand and supply at the district level. Some related issues addressed are: (i) whether the gap between demand and supply responds to poverty; and (ii) whether recent hikes in NREGS wages are inflationary. Our analysis confirms responsiveness of the positive gap between demand and supply to poverty. Also, apprehensions expressed about the inflationary potential of recent hikes in NREGS wages have been confirmed. More importantly, higher NREGS wages are likely to undermine self-selection of the poor in it.
