Role Perception and Performance of Privately Practicing Paravets in Delivery of Animal Health Services at Farmers' Doorstep: an Exploratory Study in India.

Privately practicing paravets have been under value assessment since a long time vis-à-vis delivery of prompt and efficient animal husbandry services at farmer's doorstep. Wide variation in educational qualifications, training duration, and the shortage of veterinarians could act as impetus to test suitability of service provider to availability, accessibility, acceptability, adequacy, and affordability by farmers. The present study was conceptualized to analyze the role perception by delineating role priorities and to assess the role performance of paravets in perspective of stakeholders, namely trainers of paravet schools and paravets themselves. In the study, analytical hierarchical process (AHP) has been used to establish role priority for para-veterinary services. Two indices, namely, role performance index (RPI) and perceived effective index of measures (PEIM), were devised to assess the prospects of effective delivery of minor veterinary services. Results indicated that paravets perceived roles under productive services as first priority, followed by preventive services, curative services, while miscellaneous services as last priority (0.237), while trainers perceived preventive services as the first priority. Results of chi-square test revealed that variables such as age, experience, and educational qualification of trainers were found significant and had a positive association with the scores of evaluative role performance of minor veterinary services and perceived effectiveness of measures to improve para-veterinary services.

Maturity indices as an index to evaluate the quality of sulphur enriched municipal solid waste compost using variable byproduct of sulphur.

The aim of this study was to assess the maturity indicators of municipal solid waste compost (MSWC) enrichment with different byproduct of (sugar and fertilizer industry) sulphur (S). The concentration of total S (TS), water-soluble S (WSS), HCl extractable S and available S were significantly different in composts prepared through different byproduct of S with MSW. WSS varied from 4.6 to 5.9% of TS after 120 days of the composting period, whereas, available S varied from 14.5 - 8.6% of TS. S enriched MSW compost had lower C/N, C/S ratio and higher nitrification index as well as lower phyto-toxicity, demonstrating that composts are properly matured and stabilised. Highest compost quality index (0.97) was recorded with S1 compost. Arylsulphatase activity significantly increased with compost maturity. Results stated that all S enriched products maintained a superior amount of plant nutrients and quality indices, indicating that S enriched compost could be a possible substitute for expensive fertilizers.

Confirmation of Induced Tolerance to Alternaria Blight Disease in Indian Mustard (Brassica juncea L.).

Indian mustard (Brassica juncea L.) is an important edible oilseed crop in India. Low productivity is the major concern which is adversely affected by biotic stresses. Alternaria blight (Alternaria brassicae) is one among major diseases that has no resistant cultivar until now. Keeping in view, an experiment was conducted for isolation of Alternaria blight-tolerant mutants in Indian mustard using gamma radiation and EMS mutagens during four consecutive years in Rabi (winter season). Furthermore, the morphologically and economically superior mutants of Brassica juncea were screened artificially at cotyledonary and adult stage against Alternaria blight. Tolerance to Alternaria blight is observed in DRMR-M-163 (11.7%), DRMR-M-158 (13.1%), DRMR-M-174 (13.8%) and DRMR-M-177 (18.6%) with minimum conidia in infected cotyledons. Mutant DRMR-M-178 (19.8%) had the highest radical scavenging activity, while DRMR-M-162 (104.9 mg/g AAE), DRMR-M-169 (96.9) and DRMR-M-161 (96.9) had higher antioxidant capacity that appears to act as defence to pathogen. DRMR-M-168 (8.4%), DRMR-M-173 (8.3), DRMR-M-171 (7.9), DRMR-M-165 (7.4), DRMR-M-175 (7.2) and DRMR-M-172 (6.9) had higher phenol content which may be responsive for resistance, although DRMR-M-161 (192.7 mg/g), DRMR-M-163 (187.7 mg/g), DRMR-M-164 (132.7 mg/g), DRMR-M-167 (149.3 mg/g), DRMR-M-173 (196.0 mg/g) and DRMR-M-178 (192.7 mg/g) mutants are found to contain low levels of total soluble sugar compared with susceptible Rohini (379.3). Based on biochemical parameter's similarity, mutants are grouped in 4 major clusters. Cluster 4 contained significantly different mutant DRMR-M-172. Relative expression of mitogen-activated protein kinase 3 (MAPK3) gene was found highest in DRMR-M-177, DRMR-M-174, DRMR-M-175, DRMR-M-178, DRMR-M-170, DRMR-M-176, DRMR-M-172 and DRMR-M-173 which resulted the better response to AB stress. Based on biochemical analysis, realtime PCR and cluster analysis, DRMR-M-172 mutant appears more tolerant to Alternaria. DRMR-M-178, DRMR-M-167 and DRMR-M-177 mutants seem tolerant and could be utilized for further breeding programme.

Revisiting the plant growth-promoting rhizobacteria: lessons from the past and objectives for the future.

Plant beneficial rhizobacteria (PBR) is a group of naturally occurring rhizospheric microbes that enhance nutrient availability and induce biotic and abiotic stress tolerance through a wide array of mechanisms to enhance agricultural sustainability. Application of PBR has the potential to reduce worldwide requirement of agricultural chemicals and improve agro-ecological sustainability. The PBR exert their beneficial effects in three major ways; (1) fix atmospheric nitrogen and synthesize specific compounds to promote plant growth, (2) solubilize essential mineral nutrients in soils for plant uptake, and (3) produce antimicrobial substances and induce systemic resistance in host plants to protect them from biotic and abiotic stresses. Application of PBR as suitable inoculants appears to be a viable alternative technology to synthetic fertilizers and pesticides. Furthermore, PBR enhance nutrient and water use efficiency, influence dynamics of mineral recycling, and tolerance of plants to other environmental stresses by improving health of soils. This report provides comprehensive reviews and discusses beneficial effects of PBR on plant and soil health. Considering their multitude of functions to improve plant and soil health, we propose to call the plant growth-promoting bacteria (PGPR) as PBR.

Growth Pattern and Clinical Profile of Indian Children with Classical 21-Hydroxylase Deficiency Congenital Adrenal Hyperplasia on Treatment.

OBJECTIVE: To prospectively assess the growth parameters in a cohort of children with classical 21-hydroxylase deficiency congenital adrenal hyperplasia, comprehensively profile their clinical data and evaluate the prevalence of testicular adrenal rest tumors among affected boys. METHODS: Children with congenital adrenal hyperplasia aged 0-18 y were prospectively followed up for six mo to 2 y (mean follow-up: 17 ± 6 mo). Baseline data were obtained by interviewing parents and from clinic records. Anthropometry, biochemical parameters, X-ray for bone age, and ultrasound scrotum (in boys >5 y) for testicular adrenal rest tumors were performed. RESULTS: Among the 81 children (32 boys, 49 girls), two-thirds (57) had salt-wasting and the remaining had simple virilizing type and the mean age at enrolment was 6.2 ± 4.9 y. The overall height standard deviation score was -0.6 (-2.0 to 0.8) with a greater compromise in children in the age groups 0-2 y and > 10 y and those with salt-wasting type. Overall, 25 (31%) children had short stature and 45 (55.6%) had growth velocity below the reference range. Bone age advancement beyond 2 standard deviation score was seen in 46% of children assessed. Testicular adrenal rest tumors were detected in 5 out of 21 boys (23.8%). CONCLUSIONS: The auxological pattern observed in this homogenously-managed Indian pediatric cohort with congenital adrenal hyperplasia highlights that infancy and peri-pubertal age groups are the most vulnerable, reiterating the importance of diligent growth monitoring. The high prevalence of testicular adrenal rest tumors merits the incorporation of annual ultrasound in the follow-up protocol of these patients.

Assessment of Awareness about Antibiotic Resistance and Practices Followed by Veterinarians for Judicious Prescription of Antibiotics: An Exploratory Study in Eastern Haryana Region of India.

The rise of antibiotic resistance and its global outreach has recently become a subject of increasing importance in veterinary research with an objective to reduce the load of antibiotic resistance in dairy farming practices. The present study was designed to analyze antibiotic prescriptions by veterinarians and to evaluate the appropriateness of prescribing behavior in consistent with prudent use of antibiotics. A total of 48 veterinarians were selected randomly from government Veterinary hospitals constituting a total of 48 veterinarians as respondents. The study revealed that most of prescriptions corresponded sound to prudent use of antibiotic and its treatment guidelines. To assess their awareness about antibiotic resistance and its related veterinary practices, an exclusively Awareness Index of antibiotic resistance was developed. It was observed that antibiotics were prescribed in initial encounter of diagnosis; thus, antibiotic conservation practices were found lacking. The ethical awareness of veterinarians was found lacking to establish valid veterinary-client relationship and ensure active involvement of stakeholders. This study largely looks into this angle by unearthing the drug prescribing behavior in order to shape the interdisciplinary research on this biological and profoundly social issue.

Restoration of carbon and microbial activity in salt-induced soil by application of peanut shell biochar during short-term incubation study.

For the present study, soil samples of four artificially-induced salinity gradients (S0: control, S1: 2.0, S2: 4.0, S3: 6.0 ECiw) was incubated with fine-textured peanut shell biochar at various ratios (B0: control, B1: 2.5%, B2: 5.0%, B3: 10% w/w) for 30 days. At 1, 3, 7, 15, 30 days of incubation, samples were analyzed for soil carbon and selected enzyme activities. Results showed that biochar could increase soil organic carbon on application of highest rate of biochar addition (B3), hence potentially restored the saline soils by less C mineralization, and more sequestration of soil C. However, soil enzyme activities were biochar rate(s), day(s) of incubation and enzyme dependent. The lowest rate of biochar addition (B1) showed highest dehydrogenase (20.5 µg TPF g(-1) soil h(-1)), acid phosphatase (29.1 µg PNP g(-1) soil h(-1)) and alkaline phosphatase (16.1 µg PNP g(-1) soil h(-1)) whereas the higher rate (B2) increased the urease (5.51 µg urea-N g(-1) soil h(-1)) and fluorescein diacetate hydrolyzing activities (3.95 µg fluorescein g(-1) OD soil h(-1)) in soil. All the positive changes persisted at higher levels of salinity (S2, S3) suggesting biochar-amended soil may be potential for better nutrient cycling. Soil enzymes were found to be correlated with soil carbon and with each other while principal component analysis (PCA) extracted the most sensitive parameters as the acid and alkaline phosphatases and urease activities in the present experimental condition. This is the first time report of examining soil microbial environment using peanut shell biochar under a degraded (saline) soil.

Enhancement of Neuromuscular Activity by Natural Specimens and Cultured Mycelia of Cordyceps sinensis in Mice.

The present study was aimed to evaluate the effect of natural specimen and laboratory cultured mycelia of Cordyceps sinensis on neuromuscular activity in mice. The powder of natural specimen and laboratory cultured Cordyceps sinensis was orally administered at the dose rate of 100, 300 and 500 mg/kg for 30 days. Natural specimen and in vitro propagated Cordyceps sinensis showed significant (P<0.05) enhancement in neuromuscular endurance and antidepressant activity at 300 and 500 mg/kg as compared to the control group. However, the fungus did not proved to be as effective as fluoxetine in exhibiting antidepressant action. Muscular endurance was determined on a Rota rod apparatus while antidepressant (mood elevating) activity was measured on a photoactometer in Swiss albino mice. The effects produced by both natural specimens and laboratory cultured Cordyceps sinensis were comparable and showed almost equal potency.

Comparison of contraceptive choices of rural and urban US adults aged 18-55 years: an analysis of 2004 behavioral risk factor surveillance survey data.

INTRODUCTION: Although sexually active US adults wanting to prevent pregnancy have a wide variety of birth control methods readily available, there is little research that documents the contraceptive choices of rural adults in comparison to urban adults. This study compared the contraceptive choices of rural with urban adults. The comparative analysis joins the recent dialog in population health focused on assessing health related differences to detect if these are indicative of rural health disparities. DESIGN: This was a cross-sectional study analyzing 2004 Behavioral Risk Factor Surveillance Survey (BRFSS) data. Place of residence was ascertained by re-coding the state/county FIPS code as either urban or rural, based on 2003 Rural-Urban Continuum Codes from the US Office of Management and Budget (setting: US households; participants: US adults 18-55 years). MAIN OUTCOME MEASURES: characteristics and contraceptive method choice of rural adults using birth control. RESULTS: A multivariate regression model performed with 'use of birth control' as the dependent variable yielded that rural in comparison with urban adults 18-55 years were more likely to use female or male sterilization, non-injectable and injectable hormones for birth control. They were less likely to use: condoms, a diaphragm or NuvaRing, emergency contraception, withdrawal or rhythm methods. Additionally, in comparison with urban adults, rural persons younger than 35 years, those who had children younger than 18 years living with them, those who were partnered, males and those living in households with an income of less than US$35,000 were more likely to report using some form of contraception. CONCLUSION: There were differences in the contraception choices of urban and rural adults. How much primary care provider preferences explains the differences is not known and bears further exploration. These results should prove useful to healthcare providers as well as public health family planning programs.

Comparative efficacy of different anthelmintics against fenbendazole-resistant nematodes of pashmina goats.

A trial using albendazole, albendazole plus rafoxanide combination, ivermectin and doramectin was conducted in Pashmina goats having history of fenbendazole resistance to Haemonchus spp. and maintained at high altitude (>2350 m above sea level). Day 0 infection level was variable in different groups of animals and their larval cultures indicated Haemonchus, Trichostrongylus, Ostertagia and Oesophagostomum spp. infection, in addition to Nematodirus spp. as observed in egg counts. Efficacy of drugs was calculated on day 14 post treatment by faecal egg count reduction test (FECRT). Albendazole was least effective (14%) followed by its combination with rafoxanide (54%). However, ivermectin and doramectin were 96% and 94% effective against gastrointestinal nematodes of Pashmina goats. It was concluded that use of albendazole and its combination with rafoxanide are ineffective in controlling the nematodes of goats at this farm; hence, future use must be avoided. However, regular monitoring of the efficacy of ivermectin and doramectin is needed.

Neurological complications in Chikungunya fever.

OBJECTIVE: The present prospective study was undertaken to study the clinical manifestations and mainly neurological complication of an acute febrile illness termed chikungunya which has recently attacked india after 43 years. METHOD: This prospective study has been conducted in hospitalised patients admitted in government and private hospitals of Kota city from August 2006 to October 2006. Patients showing neurological involvement with typical clinical picture of chikungunya infection were studied in detail and followed up for improvement and any permanent damage or death. RESULTS: Apart from typical clinical triad of high grade fever, arthralgia and rash of chikungunya infection we have observed a spectrum of neurological abnormalities in terms of altered mental functions, seizures, focal neurological deficit with abnormal CT scan of head and altered CSF biochemistry. Permanent neurological sequelae and even death has occurred. CONCLUSION: Typical clinical history of chikungunya infection, neurological complications with associated CSF abnormalities, supportive laboratory evidences, positive chikungunya IgM card test, exclusion of other causes and known predilection of arboviruses for CNS infection allows us to conclude the diagnosis of study cases as Chikungunya Encephalitis.

Immunocytochemistry on scrape cytology in breast cancer: will it unearth the weaker positives?

OBJECTIVE: To standardize the technique of immunocytochemical (ICC) assessment of estrogen (ER) and progesterone receptor (PR) status in breast cancer by scrape cytology and to compare the results with immunohistochemistry on paraffin blocks. STUDY DESIGN: ICC assessment for ER and PR was done on scrape smears from tissue samples in 200 cases of primary breast cancer. The results were compared to those obtained from immunohistochemical (IHC) evaluation of formalin-fixed paraffin same tissue samples. RESULTS: ER/PR positivity rates as well as staining scores were compared between the scrape smears and tissue sections. The concordance between cytology and histology was 84% for ER and 90% for PR. Both the positivity rates and the staining intensity scores were higher for cytochemistry than for histochemistry. CONCLUSION: The ICC method on scrape smears is a simple test with rapid turnaround time. The sample required is small, and antigen loss due to fixation and processing is minimal. This new method gives a higher yield of hormone receptor positivity and, when used in conjunction with the IHC method, may improve the pickup rate of ER-positive cases, thereby playing an important role in risk stratification and therapeutic decision making in patients with breast cancer.

Legionnaires' disease in long-term care facilities: overview and proposed solutions.

Pneumonia is a leading cause of morbidity and mortality in nursing home patients. In acute care hospitals, there is considerable evidence to indicate that Legionnaires' disease is a significant cause of nosocomial pneumonia, the source of which is the potable water system. A relatively limited amount of data exists as to the role of Legionnaires' disease as a cause of pneumonia acquired in long-term care residents. Several lines of evidence suggest that Legionnaires' disease may be an important but underrecognized cause of pneumonia in long-term care residents. These include reports of outbreaks, prospective studies of community-acquired pneumonia that include nursing home patients, and prospective studies of individual long-term care facilities linking Legionnaires' disease to colonization of the potable water system with Legionella. Multiinstitutional studies combining environmental and clinical surveillance for Legionella are needed to further confirm the relationship between colonization of potable water and the occurrence of disease in the long-term care facilities. Until these studies are completed, it is recommended that individual facilities undertake annual sampling of the potable water system for Legionella, coupled with introduction of the rapid Legionella urinary antigen test should L. pneumophila serogroup 1 be found.

Sociodemographic characteristics of HIV infection in northern India.

134 patients testing positive for HIV antibody during the period 1986-1993 were included in the present study. An in-depth analysis of the subjects revealed that the adult males seemed to have the highest propensity for HIV infection in this part of the country. Marital status had no bearing on incidence and route of seropositivity. This was not so in females. Extramarital heterosexual contact was the mode of HIV acquisition in adults in contrast to blood transfusion in children. Clinically, most of these patients were still asymptomatic. At presentation, oral Candidiasis was common. Pneumocystis carinii pneumonia (PCP) was the leading cause of death.

PIP: Data are analyzed from 134 HIV positive individuals who were referred to the National AIDS Control Organization of the Indian Government for clinical management during June 1986-June 1993. The center was a major referral center for northern India. HIV was determined by enzyme linked immunosorbent assay (ELISA). Retesting was conducted. The population was grouped as under and over 13 years of age. Laboratory testing was performed in order to determine the absolute lymphocyte count (ALC), the absolute and percentage of CD4+ and CD8+ lymphocyte counts and CD4/CD8 ratios, immunoglobulins, and delayed-type cutaneous hypersensitivity (DTH). Findings indicated an increase in HIV positive cases over time and a greater number of adults who were HIV positive. The mean age was 27.2 years for males and 22.2 years for females. The youngest age was 1.5 years. 116 HIV positive people were Indians, and most lived in metropolitan areas of northern India. 25 were children. 25 lived in neighboring villages of Haryana, Punjab, and around Delhi. Marital status appeared to be unrelated to HIV status. 51 men were single and 46 were married and seropositive due to sexual contacts. 4 women were single and 8 were married. Of the 4 single women, 2 were sexually very active with multiple partners. 6 of the 8 married females acquired HIV infection through their spouses. The other 2 received HIV infected blood transfusions. 39.5% of men and 75% of women acquired HIV infections from heterosexual contacts. 29% of transmission was due to contaminated blood and blood products. The HIV infected male population comprised mainly businessmen and defense personnel. HIV infected persons came mainly from the Bombay-Pune area. 66.6% of persons infected from contaminated blood were from Delhi. Asymptomatic PGL and ARC screenings were the common reason for referral to the center. 13 of the 134 have already died. The most common cause of death was Pneumocystis carinii pneumonia. The most common opportunistic infection was candidiasis.

Surveillance of STD patients for AIDS using World Health Organisation criteria.

PIP: The World Health Organization (WHO) criteria for HIV clinical disease were tested among individuals with high-risk behavior in northern India. A questionnaire, based upon history and physical examination alone, standardized by the WHO to include both major and minor signs necessary for the clinical diagnosis of AIDS in adults was applied to 165 consecutive patients attending the STD clinic of Dr. R.M.L. Hospital, New Delhi. All patients were screened for the presence of STDs by the dermatologist in charge of the clinic, with patients fulfilling two major and at least two minor WHO criteria eventually classified as having clinical AIDS based upon the WHO case definition. Each of those patients was subjected to serological confirmation of the clinical suspicion using ELISA and Western blot commercial tests. Of the 165 patients screened, a definite diagnosis of STD was possible in 85. These patients were 20-45 years old (mean age, 30.59 years). All were male and chancroid was the most common STD in the cohort. Of the 85, only one satisfied the WHO clinical criteria for AIDS. Serological investigations, ELISA, and Western blot confirmed the subject's HIV-seropositive status. These results indicate that in northern India, clinical HIV disease remains rare even among individuals with high-risk behavior. The low prevalence of clinical HIV disease in that part of the country makes it difficult to assess the specificity and sensitivity of the WHO clinical criteria for AIDS.^ieng

Hypocalcemia-induced reversible hemodynamic dysfunction.

A series of three cases of 'hypocalcemic dysfunction' that reflects a range of clinical profiles from a purely calcium responsive peripheral collapse to paroxysmal nocturnal dyspnea and orthopnea is reported. The underlying diversity of clinical presentation is noteworthy, as is its prompt response to calcium therapy.

Effect of aerosolised verapamil and nifedipine in bronchial asthma.

Twenty patients of bronchial asthma were given 5 mg of either nifedipine or verapamil as aerosol therapy in a randomized fashion. Both drugs showed a statistically significant improvement in FVC, PEFR at zero hours lasting through 90-120 minutes. Changes in respiratory rate, pulse rate, blood pressure were insignificant with verapamil while appreciable tachycardia and transient fall in BP occurred with nifedipine therapy.

Hepatic involvement in tuberculosis.

Seventy one cases of pulmonary and extrapulmonary tuberculosis (confirmed by clinical, sputum examination, Skiagram, lymph node or other organ biopsy) and 13 cases of PUO suspected to be tubercular in origin were included in the study. Besides, thorough clinical workup, LFTs and liver biopsy were also done in all cases. LFT alterations were seen in only 5 (7%) cases of tuberculosis while in PUO group, 3 (23%) cases showed deranged LFT. In all, alteration in SGOT/SGPT was most frequent observation. In Liver biopsy, histopathological changes were seen in 63 percent (45 out of 71) of cases of tuberculosis and in 46.16 percent cases of PUO. In tubercular cases, various abnormalities observed were caseating granulomas: 18.30 percent, nonspecific inflammatory infiltration: 25.32 percent, focal Kupffer cell hyperplasia: 11.2 percent and fatty changes: 8.45 percent. Four of the PUO cases, showing Kupffer cell hyperplasia and non-specific inflammatory infiltration responded to antituberculous therapy. Thus it is surmised that though the caseating granuloma is the hallmark of tuberculosis, but nonspecific inflammatory hepatitis and retothelial tubercle nodules may be the forerunner in the evolution of granuloma.
