RESUMO

Conservation practices focusing on improving the soil and water quality of working lands are implemented across the United States, supported partially through the United States Department of Agriculture Natural Resources Conservation Service cost-share or incentive payment programs. We assess whether participation in federal conservation support programs induces a change in the number of conservation practices adopted by farmers. We also identify the factors that affect the adoption intensity of different best management practices. We use survey data collected from Louisiana farmers and estimate models using the matching method and Poisson quasi-likelihood model. We find that participation in the cost-share or incentive program leads to an increase in the number of conservation practices on the farms. Similarly, the use of precision technology application and farm being integrated are likely to have a higher number of on-farm conservation practices. Results have implications for federal working lands conservation support programs in the United States.

RESUMO

A high strength chemical industry wastewater was assessed for its impact on anaerobic microbial community dynamics and consequently mesophilic methane generation. Cumulative methane production was 251 mL/g total chemical oxygen demand removed at standard temperature and pressure at the end of 30 days experimental period with a highest recorded methane percentage of 80.6% of total biogas volume. Volatile fatty acids (VFAs) analysis revealed that acetic acid was the major intermediate VFAs produced with propionic acid accumulating over the experimental period. Quantitative analysis of microbial communities in the test and control groups with quantitative real time polymerase chain reaction highlighted that in the test group, Eubacteria (96.3%) was dominant in comparison with methanogens (3.7%). The latter were dominated by Methanomicrobiales and Methanobacteriales while Methanosarcinaceae in test groups increased over the experimental period, reaching a maximum on day 30. Denaturing gradient gel electrophoresis profile was performed, targeting the 16S rRNA gene of Eubacteria and Archaea, with the DNA samples extracted at 3 different time points from the test groups. A phylogenetic tree was constructed for the sequences using the neighborhood joining method. The analysis revealed that the presence of organisms resembling Syntrophomonadaceae could have contributed to increased production of acetic and propionic acid intermediates while decrease of organisms resembling Pelotomaculum sp. could have most likely contributed to accumulation of propionic acid. This study suggested that the degradation of organic components within the high strength industrial wastewater is closely linked with the activity of certain niche microbial communities within eubacteria and methanogens.

RESUMO

Rural communities are resource-constrained and at higher risk of obesity and obesity-related conditions. Thus, studying self-assessed health status and underlying vulnerabilities is critical to provide insights to the program planners for effective and efficient planning of obesity prevention programs. This study aims to investigate the correlates of self-assessed health status and subsequently determine the obesity vulnerability level of residents in rural communities. Randomly sampled data were obtained from in-person community surveys in three rural Louisiana counties-East Carroll, Saint Helena, and Tensas-in June 2021. The association of social-demographic factors, grocery store choice, and exercise frequency with self-assessed health was investigated using the ordered logit model. An obesity vulnerability index was constructed using the weights obtained from the principal component analysis. The results show that gender, race, education, possession of children, exercise frequency, and grocery store choice significantly influence self-assessed health status. Around 20% of respondents fall into the most-vulnerable segment and 65% of respondents are vulnerable to obesity. The obesity vulnerability index ranged from -4.036 to 4.565, indicating a wide heterogeneity in the vulnerability level of rural residents. The findings show that the self-assessed health status of rural residents is not promising along with a high level of vulnerability to obesity. The findings from this study could serve as a reference in the policy discussion regarding an effective and efficient suite of interventions in rural communities to address obesity and promote well-being.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death, with 80% of the total death occurring in low- to middle-income countries (LMICs). Nepal is one of the LMIC; COPD is a highly prevalent and significant public health issue often underdiagnosed. Medical physicians' good knowledge and practice to diagnose and treat COPD can help reduce the disease burden. OBJECTIVES: To determine the level of knowledge, practice and factors influencing the practice of physicians regarding COPD management based on GOLD guidelines. DESIGN: A cross-sectional descriptive study using a structured questionnaire was conducted among medical physicians working in Bagmati and Gandaki province of Nepal. Out of total scores, physicians knowledge and practice were graded according to Bloom's original cut-off point for good (≥80%), satisfactory (60%-78%) and poor (<60%). RESULT: A total of 152 medical physicians participated in this study. Out of the possible total score 20, the mean score on knowledge was 17.8 ± 2.4, and out of possible total score eight, the mean score on practice was 5.3 ± 1.3. The correlation test between total knowledge and practice scores showed r = 0.18 and p value <0.02. The most selected factors hindering the appropriate management of COPD was lack of patient follow up and lack of professional training in COPD. Other factors included patient unwillingness to discuss smoking quit plan, lack of screening tool, unavailability of spirometry and physician unawareness of available medicine to treat COPD. CONCLUSION: Despite physicians having good knowledge in COPD, the practice in COPD management is below guideline-recommended. There is a significant, very low positive correlation between total knowledge score and practice score. Proper COPD training to physicians, disease awareness among patients, easy availability of diagnostic equipment and medication can help improve physicians' practice and appropriately manage COPD patients.

RESUMO

BACKGROUND: Panchavalkala Kwatha and Jatyadi Taila are recommended for cleaning and healing of non-healing ulcers such as Diabetic Foot Ulcer (DFU) and Varicose Ulcers (VU). OBJECTIVES: Innovative topical aerosol sprays viz. Panchavalkala Kwatha Aerosol Spray (PKS) and Jatyadi Taila (Healz) Aerosol Spray (JTS) were evaluated for healing in DFU & VU against conventional treatment. MATERIALS & METHODS: After obtaining approval from Ethics Commitees & informed consent, 53 patients were randomized in two study groups. In one group, ulcer cleaning was done with PKS and then JTS was used for dressing while in other group, cleaning was done with Hydrogen peroxide and/or Hypochlorite followed by dressing with 10% Povidone iodine. Ulcer examination was done from baseline to every 7th day by Bates Jensen ulcer assessment tool, digital photographs and photographic ulcer assessment tool. Comparison of categorical variables was done using t-test. RESULTS: The dual action of PKS and JTS exhibited potentially comparable effect to the conventional treatment. CONCLUSION: PKS and JTS were found to be effective, comfortable, hygenic and acceptable in management of chronic ulcers.

RESUMO

OBJECTIVES: Chikungunya and scrub typhus infection are important causes of undifferentiated fever in tropical zones. The clinical manifestations in both conditions are nonspecific and often overlap. This study compares the clinical manifestations and the outcome of chikungunya with chikungunya-scrub typhus coinfection in children. METHODS: A hospital-based observational study was conducted in children below 15 years of age over 16-month duration in 2017-2018. Chikungunya was diagnosed by IgM ELISA. All positive chikungunya cases were subjected to scrub typhus testing, dengue testing, leptospira testing, and malaria testing. Clinical manifestations and outcomes of all patients were recorded. RESULTS: Out of the 382 admitted cases with fever, 11% (n = 42) were diagnosed with chikungunya, and the majority (n = 30, 71.4%) were male. Among the 42 chikungunya cases, 17 (40.5%) tested positive for scrub typhus and one positive for falciparum malaria. Out of a total of 42 chikungunya cases, myalgia, nausea/vomiting, headache, abdominal pain, lymphadenopathy, hepatomegaly, splenomegaly, and edema were 81%, 73.8%, 66.7%, 64.3%, 59.5%, 52.4%, 40.5%, and 38.1%, respectively. Besides, altered sensorium (31%), jaundice (26.2%), dry cough (21.4%), shortness of breath (19%), and seizures (16.7%) were other clinical manifestations present in this group of children. Patients with chikungunya-scrub typhus coinfection reported headaches, pain in the abdomen, dry cough, shortness of breath, seizures, and splenomegaly, significantly more (p value < 0.05) compared to those with chikungunya only. Thirteen (31%) children developed shock, five in the chikungunya group and eight in the chikungunya-scrub typhus coinfection group. Six children in the coinfection group received inotrope. Among the chikungunya-only cases, 22 recovered and one died, whereas in the chikungunya-scrub typhus coinfection group, fourteen recovered and three died. CONCLUSIONS: Both the chikungunya and scrub typhus coinfection groups shared many similar clinical manifestations. In children, coinfection with scrub typhus often leads to modification of the clinical profile, complications, and chikungunya outcome.

RESUMO

Cryptococcal meningitis (CM) is mostly seen in immune-compromised patients and rarely occurs in immune-competent individuals. Immunocompetent individuals with CM present with indolent neurological disease and have better clinical outcomes after treatment. However, misdiagnosis is common and these patients may suffer from serious complications with high mortality.

RESUMO

BACKGROUND: Small for gestational age (SGA) is common among newborns in low-income countries like Nepal and has higher immediate mortality and morbidities. OBJECTIVES: To study the prevalence and prognostic factors of SGA babies in Western Nepal. METHODS: A cross-sectional study (November 2016-October 2017) was conducted in a tertiary care hospital in Western Nepal. Socio-demographic, lifestyle factors including diet, and exposures including smoking and household air pollution in mothers who delivered newborns appropriate for gestational age (AGA), SGA and large for gestational age (LGA) were recorded. Logistic regression was carried out to find the odds ratio of prognostic factors after adjusting for potential confounders. RESULTS: Out of 4000 delivered babies, 77% (n = 3078) were AGA, 20.3% (n = 813) were SGA and 2.7% (n = 109) were LGA. The proportion of female-SGA was greater in comparison to male-SGA (n = 427, 52.5% vs n = 386, 47.5%). SGA babies were born to mothers who had term, preterm, and postterm delivery in the following proportions 70.1%, 19.3%, and 10.6%, respectively. The average weight gain (mean ± SD) by mothers in AGA pregnancies was 10.3 ± 2.4 kg, whereas in SGA were 9.3 ± 2.4 kg. In addition to low socioeconomic status (OR 1.9, 95% CI 1.1, 3.2), other prognostic factors associated with SGA were lifestyle factors such as low maternal sleep duration (OR 5.1, CI 3.6, 7.4) and monthly or less frequent meat intake (OR 5.0, CI 3.2, 7.8). Besides smoking (OR 8.8, CI 2.1, 36.3), the other major environmental factor associated with SGA was exposure to household air pollution (OR 5.4, 4.1, 6.9) during pregnancy. Similarly, some of the adverse health conditions associated with a significantly higher risk of SGA were anemia, oligohydramnios, and gestational diabetes. CONCLUSIONS: SGA is common in Western Nepal and associated with several modifiable prognostic factors.

RESUMO

BACKGROUND: Despite readily availability of vaccines against both Hemophilus influenzae and Pneumococcus, pneumonia remains the most common cause of morbidity and mortality in children under the age of five years in Nepal. With growing antibiotic resistance and a general move towards more rational antibiotic use, early identification of clinical signs for the prediction of radiological pneumonia would help practitioners to start the treatment of patients. The main aim of this study was to reassess the clinical predictors of pneumonia in Nepal. METHODS: This cross-sectional study was conducted between June 2015 and November 2015 at Tribhuvan University Teaching Hospital, a tertiary hospital in Kathmandu, Nepal. Children aged 3-60 months with a clinical diagnosis of pneumonia by a physician were enrolled in the study. Radiological pneumonia was identified and categorized as per World Health Organization guidelines by an experienced radiologist blinded to patient characteristics. We calculated sensitivity and specificity of clinical signs and symptoms for radiological pneumonia. RESULTS: Out of 1021 children with fever, 160 cases were clinically diagnosed as pneumonia and were enrolled for this study. Among the enrolled patients, 61% had radiological pneumonia. Tachypnea had the highest sensitivity of 99%, while bronchial breathing had the highest specificity of 100%. During univariate analysis, grunting, wheezing, nasal discharge, decreased breath sounds, noisy breathing and hypoxemia were associated with radiological pneumonia. Only hypoxemia remained an independent predictor when adjusted for all the factors. CONCLUSION: Tachypnea was the most sensitive sign, whereas bronchial breathing was most specific sign for radiological pneumonia.

RESUMO

Extracellular biopolymer produced from Klebsiella terrigena was found to have excellent flocculating ability over a wide range of colloid particles (0.5 to 25micro). The biopolymer was thermostable, with an optimum temperature for flocculation of 30 degrees C. Analysis with Fourier transform infrared spectrophotometry (FT-IR) shows that the biopolymer mainly possesses hydroxyl, carboxyl, and methoxyl groups, with neutral sugar and uronic acid as its major and minor components, and the structure of a polysaccharide. The average molecular weight of the biopolymer was greater than 2 x 10(3) kilodalton (KDa), as determined by gel permeation chromatography. Scanning electron microscopy indicated a porous morphology of the biopolymer. At a dosage of 2 mg/L, the purified biopolymer could remove 62.3% of Cryptosporidium oocysts (1 x 10(6)) spiked in tap water samples. Calcium (5mM) was required for effective removal. The removal efficiency of Cryptosporidium oocysts by the biopolymer remained unaltered over a pH range of 6 to 8. The results of this study indicates a possible utility of the Klebsiella terrigena biopolymer as an alternative to typically used chemical flocculants for removal of Cryptosporidium oocysts from water.

RESUMO

This study evaluated the potential of an extracellular, novel biopolymeric flocculant produced by a strain of Klebsiella terrigena for removal of Salmonella, a potent pathogen prevalent in poultry wastewater. The purified biopolymer was applied to poultry wastewater containing 3 log CFU cells of Salmonella. An optimized dosage of 2 mg L(-1) of the purified bioflocculant was sufficient to remove 80.3% Salmonella spp. within 30 min, at ambient temperature. Also this bioflocculant showed high flocculating activity (90%) against kaolin particles and proved to be far more effective than the other synthetic flocculants used in this study. Fluorescent in situ hybridization (FISH) with the genus specific Sal3 probe hybridized with the Salmonella present in the agglomerated matrix of the bioflocculant. Confocal laser scanning micrographs (CLSM) allowed a clear visualization of the spatial distribution of the total flocculated bacterial population (with DAPI and Eub338 probe) as well as Salmonella (with the Sal3 probe), indicating that the removed Salmonella remained bound and embedded within the flocculant matrix. Scanning electron microscopic (SEM) analysis exhibited a porous surface morphology. The bioflocculant was characterized to be a polysaccharide by FTIR, HPLC, CHN and chemical analysis. A viable alternative treatment technology of poultry wastewater using this novel bioflocculant is suggested.

RESUMO

Research and development (R&D) offer promising clues to address a wide range of socioeconomic problems through the development of new products and services or often by improving the existing ones. High-income countries (HICs) have realized the worth of R&D and invested tremendously in that sector; however, resource-poor low-income countries (LICs) are still far behind in realizing the potential benefit that R&D could offer for economic growth and national development. Even if some LICs have a positive outlook towards the R&D sector, the trend of emulating works from HICs to solve local or regional issues have most often yielded counterproductive results. LICs are suggested primarily to focus on applied research by incorporating their socioeconomic and cultural aspects to solve their everyday problems whose investigation is often ignored in research-intensive nations. Moreover, applied research in LICs offers the potential to provide low-cost and innovative solutions to local and regional problems with global implications.

RESUMO

BACKGROUND: Scrub typhus, an important cause of unexplained fever, is grossly neglected and often misdiagnosed in low and middle income countries like Nepal. The main aim of this study was to report on the clinical profile and complications of scrub typhus and its outcome in Nepalese children. METHODS: A prospective observational study was carried out in children aged 1-16 years, admitted to a tertiary care hospital of central Nepal in between July 2016- Aug 2017. Scrub typhus was diagnosed with IgM ELISA. RESULTS: All cases of scrub typhus (n = 76) presented with fever and commonly had other symptoms such as headache (75%), myalgia (68.4%), vomiting (64.5%), nausea (59.2%), abdominal pain (57.9%), cough (35.5%), shortness of breath (22.4%), altered sensorium (14.5%), rashes (13.2%) and seizures (11.8%). Important clinical signs noticed were lymphadenopathy (60.5%), hepatomegaly (47.4%), edema (26.3%), jaundice (26.3%), and splenomegaly (15.8%). About 12% (n = 9) had necrotic eschar. Similarly, thrombocytopenia, raised liver enzymes and raised creatinine values were seen in 36.9%, 34.2% and 65.8% respectively. The most common complications were myocarditis (72.4%), hypoalbuminemia (71.1%), severe thrombocytopenia (22.4%), renal impairment (65.8%), hyponatremia (48.7%) and hepatitis (34.2%). Over two-thirds (69.70%) of the cases were treated with doxycycline followed by combination with azithromycin in the remaining 18.4%. Overall, mortality rate in this group was 3.9%. CONCLUSIONS: Scrub typhus should be considered as a differential in any community acquired acute undifferentiated febrile illness regardless of the presence of an eschar. Myocarditis and acute kidney injury are important complications which when addressed early can prevent mortality. Use of doxycycline showed a favorable outcome.

RESUMO

BACKGROUND: In Nepal, the maternal mortality ratio is 281 per thousand live births, among which 40% mortality occurs during home delivery. Home delivery increases the risk of maternal and neonatal mortality and morbidity due to the birth not assisted by skilled attendant. This study was carried out to determine the factors affecting the place of delivery among the mothers residing in Jhorahat VDC, Morang district, Nepal. METHODS: A mixed method study using interviews based on semi-structured questionnaire (n=93) among mothers and two focus group discussion among decision makers of the house and female community health volunteers was conducted between November to December 2012. For quantitative data, Chi-square test and Fischer's Exact test were used to examine the association between the selected variables and place of delivery. RESULTS: More than half (58.1%) of the mothers had institutional delivery and 41.9% of them had home delivery. The most common reason for home delivery was easy and convenient environment (66.7%) and that for institutional delivery was safety (77.8%). There was a significant association between caste, education of mothers, education of spouse, occupation of spouse, per capita income, time to reach the nearest health center, parity, previous place of delivery, number of antenatal visit, knowledge about place of delivery, planned place of delivery, and place of delivery. CONCLUSION: Maternal health services, such as prenatal care, skilled assistance during delivery and post-natal care, along with adequately equipped health institutions, play a major role in the reduction of maternal morbidity and mortality. Concerted efforts should be made both at community and government levels to increase institutional delivery.

RESUMO

INTRODUCTION: To understand and report the prevalence of meconium aspiration syndrome and the clinico-radiological features in a tertiary care hospital of western Nepal. METHODS: An observational study carried out for a year in 2014-15 in all babies with MAS. Clinical and radiological profiles of MAS in relation to gender, gestational age, mode of delivery, birth weight, Apgar score, thickness of meconium, age at admission and the immediate outcome were studied. RESULTS: Out of 584 admitted newborns (male=389; female=186) during the study period, 78 (13.4%) had meconium aspiration syndrome with male: female ratio of 1.2:1. Majority of babies admitted to NICU had thick meconium [n=52 (66.7%)]. There was no statistical significant difference in various parameters such as Apgar score at 1 and 5 minutes, respiratory distress, birth asphyxia, duration of oxygen use, MAS severity and chest x-ray in those with thick MAS compared to thin. Among all newborns with MAS, 59% (n=46) had abnormal radiological findings with over two-folds in those with thick MAS (71.7%)] compared to thin (28%). Hyperinflation (47.8%), diffuse patchy infiltration (37%), consolidation (21.7%) collapse (8.7%), right lung fissure (6.5%) and pneumothorax (8.7%) were the abnormal radiological findings seen in MAS babies. The odds of having APGAR score at 1 minute at least 7 or more was twice unlikely in those having thick meconium compared to thin (P=0.02) Conclusions: Thick meconium is relatively common with more significant abnormal radiological findings and low Apgar score.

RESUMO

In the operation of biological wastewater treatment processes, fast sludge settling during liquid-solids disengagement is preferred as it affects effluent quality, treatment efficiency and plant operation economy. An important property of fast settling biological sludge is the ability to spontaneously form big and dense flocs (flocculation) that readily separates from water. Therefore, there had been much research to study the conditions that promote biological sludge flocculation. However, reported findings have often been inconsistent and this has possibly been due to the complex nature of the biological flocculation process. Thus, it has been challenging for wastewater treatment plant operators to extract practical information from the literature. The aim of this review is to summarize the current state of understanding of the factors that affect sludge flocculation so that evaluation of such information can be facilitated and strategize for intervention in the sludge flocculation and deflocculation process.

RESUMO

BACKGROUND: Neurocysticercosis (NCC), a common cause of seizures in children from low and middle income countries (LMICs), if not diagnosed and treated early enough may lead to considerable morbidity and mortality. There is a lack of data on the prevalence of NCC and its clinical characteristics among those with seizure in South-Western Nepal. AIMS AND OBJECTIVES: To study the prevalence and clinical characteristics of NCC in children with seizures. MATERIAL AND METHODS: All children admitted to Universal College of Medical Sciences, a tertiary hospital in South-Western Nepal with seizures during 2014-16, were tested for NCC. NCC was diagnosed by neuroimaging [computerized tomography (CT) scan or magnetic resonance imaging (MRI)]. We used logistic regression to test the association between NCC with participants' characteristics and clinical symptoms. RESULTS: Among 4962 in-patient children, 168 (104 boys and 64 girls) had seizures (138 with generalized tonic clonic seizures (GTCS) and 30 with focal seizures). 43% of children with seizures had CT scan confirmed NCC. The prevalence of NCC in the oldest children (13-16 years) was significantly greater (57.1% versus 15.6%) compared to the youngest (0-4 years) one (p < 0.001). Among 72 children with NCC, the proportions of children with vesicular, calcified, and colloidal stages were 76% (n = 35), 18% (n = 13), and 6% (n = 2), respectively. Children with focal seizures had 13% more NCC compared to those with GTCS but the result was statistically not significant. The adjusted odds of having NCC among 5-8 years, 9-12 years, and 13-16 years children were 6.6 (1.78-24.60), 11.06 (2.74-44.60), and 14.47 (3.13-66.96), respectively, compared to 0-4-year-old children. Reoccurrence of seizures within the first 3 months of taking antiepileptic drug in those with NCC was approximately 3 times higher compared to those without NCC (11% versus 4%, p = 0.084). CONCLUSIONS: This study shows that NCC contributes significantly to higher prevalence of seizures in children in South-Western region of Nepal.

RESUMO

Seizures are one of the common causes for hospital admissions in children with significant mortality and morbidity. This study was conducted to study the prevalence and clinicodemographic profile of children with seizures in a tertiary care hospital of western Nepal. This prospective cross-sectional study conducted over a period of 2 years included all admitted children (2 months-16 years) with seizures. Among 4962 admitted children, seizures were present in 3.4% (n = 168) of children, with male preponderance. 138 (82.1%) children had generalized tonic-clonic seizures (GTCS) and 30 (17.9%) children had partial seizures. GTCS were more common than partial seizures in both sexes (male = 82.7%; female = 81.2%) and age groups. There was no statistical significance in the distribution of seizures (GTCS and partial seizures) with sexes (P = 0.813) and age groups (P = 0.955). Mean ages of children having GTCS and partial seizures were 8.2 ± 4.6 years and 8.2 ± 4.2 years, respectively. Loss of consciousness (55.4%), fever (39.9%), vomiting (35.1%), and headache (16.1%) were common complaints in seizure patients. Significant number of GTCS cases had fever (P = 0.041) and neurocysticercosis (n = 72; 43%) was the most common etiology in seizure patients. Idiopathic epilepsy (38 (22.6%)), meningoencephalitis (26 (15.5%)), and febrile convulsions (14 (8.33%)) were other leading disorders in children with seizures.
