Prevalence and risk estimates of Cryptosporidium oocysts infection associated with consumption of raw-eaten vegetables in Maiduguri metropolis LGAs, Northeast Nigeria.

Cryptosporidium is one of the most important protozoan parasitic pathogens, and it is a common cause of diarrhoea in humans, domestic animals, and wild vertebrates and has serious public health threats. A cross-sectional study was designed to determine the prevalence of Cryptosporidium oocysts in raw-eaten vegetables in Maiduguri Metropolitan Council (MMC) and Jere Local Government Areas (LGAs). A total of 400 samples were collected from four (4) different locations, namely Tashan Bama, Gomboru, and Monday Markets (n = 100), while fifty (n = 50) each from 202-Vegetable-Vendors and Unimaid Commercials. A total of 16 visits were conducted in all the sampling areas (twenty-five samples per visit). The Cryptosporidium oocysts were detected using the Modified Ziehl-Neelsen Staining Technique. The locations, sources, and types of raw-eaten vegetables were also assessed. The oocysts were confirmed (100×) as bright pink spherules. Data generated were analyzed using IBM-SPSS V23.0, and p ≤ 0.05 was considered significant. Out of the total samples (n = 400) analyzed, cabbage appeared to have the highest number of 10 (12.5%) of Cryptosporidium oocysts detected, while Tomato and garden egg had 9 (11.3%) and 1 (1.2%), respectively. There was a statistically significant association (χ2 = 12.5, P = 0.014) between the presence of Cryptosporidium oocysts in raw-eaten vegetables and vegetable types. Among the sources of the vegetables sampled, Alau had the highest number of Cryptosporidium oocysts, 15 (12.5%), followed by Kilari-Abdullahi and Zabarmari sources with 4 (10.0%) and 4 (5.0%), respectively. However, Jetete appeared to have the least number 2 (2.5%) of oocysts, and there was a statistically significant association (χ2= 10.4, P = 0.034) between the presence of Cryptosporidium oocysts and the sources of vegetables and fruits. The study concludes that the raw-eaten vegetables sampled from Maiduguri Metropolis were contaminated with Cryptosporidium oocysts. The study recommends that all raw-eaten vegetables should be from cleaned sources and washed before consumption. Consumers should be enlightened on the hygienic measures in the food chain in line with the Hazard Analysis and Critical Control Points (HACCP) principles.

Irrigation implementation promotes increases in salinity and nitrate concentration in the lower reaches of the Cidacos River (Navarre, Spain).

The shift from rainfed to irrigated agriculture is associated with a change in the fertilization rates due to increases in expected production and the fact of growing more N demanding crops. In addition, the circulation of irrigation return flows (IRF) mobilizes soluble salts stored in soils or geological materials. As a consequence, it implies severe modifications in the dynamics and total amount of soluble salts and nitrogen exported, especially in semi-arid watersheds. In this study, long-term data collected by the regional authorities was used to assess the effects of irrigation implementation on salinity (using electrical conductivity, EC, as a proxy) and nitrate concentration (NO3-) after the transformation of ca. 77 km2 from rainfed to irrigated agriculture in the Cidacos River (CR) watershed. The results indicate that water quality in the lower reaches of the CR was significantly modified after the diffuse incorporation of IRF. In contrast, neither EC nor NO3- were different in those monitoring stations whose contributing watersheds did not include transformed area. In addition, the temporal dynamics in the analysed variables shifted from a rainfed land signal typical in the region to an irrigated land signal, and the hydrochemical type of the CR shifted from mixed-to-Na+-mixed-to-HCO3- to mostly Na+-mixed type, typical of waters affected by IRF in the region. Groundwater EC and NO3- also increased in those wells located within the irrigated area. Although there are great uncertainties in the actual amount of salt and N reaching the CR via IRF, the expected contribution of waste water spilled into the CR is minor in comparison to other sources, mostly agricultural sources in the case of N. The observed changes have promoted the designation of the lower reaches of the CR as "affected" by NO3- pollution, and the whole CR watershed as a Nitrate Vulnerable Zone, with the emergent question about whether irrigation implementation as carried out currently in Spain is against the environmental objectives of the Water Framework Directive.

[Incidence of type 1 diabetes in Navarre (2009-2016): higher in the southern regions of the autonomous community]. / Incidencia de diabetes tipo 1 en Navarra (2009-2016): mayor en la zona sur de la comunidad.

BACKGROUND: Geographical and seasonal variations of type 1 diabetes (T1D) are useful for establishing the key ethio-pathogenic factors of the disease. The present work seeks to analyze the incidence rates of T1D in Navarre for the 2009-2016 period, its geographical distribution and seasonal variations in birth and diagnosis in affected persons. METHODS: Prospective study with one primary and three secondary sources. The completeness of the registry, determined using the capture-recapture method, was 96.08%. The confidence intervals of zone and onset season incidence rates were determined assuming an underlying Poisson distribution. Adjusted effect of onset age, sex, onset season and geographical area over changes in incidence rates were analyzed using a Poisson regression model. Comparison among areas was carried out after the corresponding adjustments of incidence by the indirect standardization method. RESULTS: Four hundred and twenty-eight new cases were detected (incidence= 8.36/100,000 inhabitants per year, CI95%: 7.58-9.19). The disease is predominant in males (63% of patients). The incidence in children under 15 years was higher than in adults (21.54, CI95%: 18.43-25.02 vs. 5.94, CI95%: 5.23-6.71; p<0.001). Incidence was highest in the four southern regions of Navarre, most of the cases being in winter and spring. No differences were found regarding birth season over incidence. CONCLUSION: Navarre maintains a high T1D incidence in childhood that decreases progressively with age. Sex, age group, geographical zone and onset season are independently associated with the incidence rates observed in the study.

Effect of phenolic compounds on the growth of selected probiotic and pathogenic bacteria.

Fruit extracts from different tissues (pulp, seed and peel) have shown antimicrobial and prebiotic activities related to their phenolic profile, although structure-specific evaluations have not been reported yet. The effect of five phenolic compounds (catechin and gallic, vanillic, ferulic and protocatechuic acids) identified in different fruits, particularly in mango, was evaluated on the growth of two probiotic (Lactobacillus rhamnosusGG ATCC 53103 and Lactobacillus acidophilusNRRLB 4495) and two pathogenic (Escherichia coli 0157:H7 ATCC 43890 and Salmonella enterica serovar Typhimurium ATCC 14028) bacteria. The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of phenolic acids ranged from 15-20 mmol l-1 and 20-30 mmol l-1 against E. coli and S. Typhimurium, respectively. For catechin, the MIC and MBC were 35 mmol l-1 and >35 mmol l-1 against E. coli and S. Typhimurium, respectively. The presence of catechin and gallic, protocatechuic and vanillic acids in MRS broth without dextrose allowed the growth of lactobacilli. Catechin combined with protocatechuic or vanillic acid mildly allowed the growth of both probiotics. In conclusion, phenolic compounds can selectively inhibit the growth of pathogenic bacteria without affecting the viability of probiotics. SIGNIFICANCE AND IMPACT OF THE STUDY: This study provides relevant information about the effects of phenolic compounds commonly present in fruit and vegetables on the growth of probiotic and pathogenic bacteria. The compounds selectively allowed the growth of probiotic lactobacilli (Lactobacillus rhamnosus GG and Lactobacillus acidophilus) and inhibited pathogenic bacteria (Escherichia coli and Salmonella Typhimurium) at the same concentration (20 mmol l-1 ). These findings can contribute to the formulation of nutraceutical products, such as synbiotics, that can restore or maintain an optimal composition of human microbiota, potentially improving the overall health of the consumer.

Effects of sustained-release trimetazidine on chronically dysfunctional myocardium of ischemic dilated cardiomyopathy - Six months follow-up result.

BACKGROUND: Ischemic cardiomyopathy is a growing burden in third world countries. So far, benefits of trimetazidine in this group of patients have been suggested by clinical trials mainly conducted in Europe. We evaluated the effect of trimetazidine on ischemic dilated cardiomyopathy in our population. METHODS AND RESULTS: 98 patients (aged 58.5±9.2 years), admitted with decompensated heart failure with previous history of MI and/or documentation of significant CAD with previous CAG, were chosen for the study. Patients were randomized into two groups - one provided with trimetazidine 35mg sustained released tablet, twice daily and the other with a placebo, along with other conventional medications. Patients were included if they had dilated LV (LVIDd>57mm) and left ventricular ejection fraction (LVEF) ≤40%. After 6 months, significantly higher number of patients in trimetazidine group were in NYHA class I (22% vs. 8%, p=0.03) and class II (56% vs. 34%, p=0.01); higher number of patients in placebo group were in NYHA class III class IV. Anginal episodes and use of sublingual nitrate per week were significantly lower in the trimetazidine group. Left ventricular diastolic dimension (59.7±5.2 vs. 65.1±6.1, p=0.001) was significantly different in the two groups as was the increase of LVEF (11% vs. 5.6%, p=0.001). Hospitalization for worsening heart failure was significantly lower in trimetazidine group (13 vs. 22, p=0.047). CONCLUSION: Trimetazidine seems to be beneficial in patients with ischemic dilated cardiomyopathy in South Asian population and larger scale study with extended follow-up is needed.

Assessing the Rehabilitation of Achilles Tendon Ruptures using Modified Teuffer and Lindholm Technique.

The aim of this study is to assess the optimum rehabilitation and the functional outcome of open repaired Achilles tendon ruptures. This study was conducted for the 18 consecutive patients of complete ruptures at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from 2012 to 2013. Two groups were considered during 6 to 18 months post-operative observation and each group consist 9 patients. In the Group I, modified Teuffer's and in Group II, Lindholm operative methods were employed for the open repair of Achille tendon. The post operative outcomes were assessed for both of the groups through the modified Thermann's scores. In this study the patients median age was seen 39 years with 72.2% male and 27.8% female. The Thompson test was found positive in pre-operative and negative in post-operative outcome. The results shown that Achilles tendon ruptures occurred in 4 to 6cm rupture site, where the rupture side was 61.1% left and 38.9% right. The subjective overall assessment of total Thermann's scores were found very good (91 to 96) in 4 cases and (90 to 98) in 3 cases for Group I and Group II, respectively. Both of the operative techniques were found accountable results for rehabilitation. Therefore, based on the further statistical evidence of higher correlations and errors it may be concluded that Achilles tendon ruptures can be treated by modified Teuffer's or Lindholm technique.

Surgical Outcome of Intradural Spinal Tumors.

Results of 63 surgically treated intradural spinal tumors between the period of October 2003 and December 2014 at Bangabandhu Sheikh Mujib Medical University (BSMMU) and in our private settings, Dhaka, were analyzed retrospectively. There were 33 males, 30 females with an average age of 52.4 years (13-70 years) and followed up for at least a year. The preoperative symptom with duration, tumors location and intradural space occupancy and the histopathological diagnosis were analyzed. Pain was evaluated by the visual analogue scale (VAS) and the neurologic function was assessed by Nurick's grade. The tumors were located as, thoracic (n=32, 50.79%), lumbar (n=16, 25.39%), cervical (n=05, 07.93%), and junctional (n=10, 15.87%, CervicoThoracic-01, Thoracolumbar-09). The histopathological diagnosis included schwannoma (n=30, 47.7%), meningiomas (n=14, 22.3%), neurofibroma, arachnoid cyst and myxopapillary ependymoma (n=03, 04.76%) each and paraganglioma (n=01, 01.59%). Among the intramedullary tumors, ependymoma (n=03, 04.76%), astrocytoma and epidermoid cyst (n=02, 03.17%), haemangioblastoma, paraganglioma and cavernous haemangioma (n=01, 01.59%) each. The VAS score was reduced in all cases from 8.0±1.2 to 1.2±0.8 (p<0.003) and the Nurick's grade was improved in all cases from 3.0±1.3 to 1.0±0.0 (p<0.005). The preoperative neurological deficit improved within 8 postoperative weeks in most cases and within 1 postoperative year in all cases. Complications included cerebrospinal fluid leakage, parasthesia and further neurological deterioration (Astrocytoma) (n=02, 03.17%) and dependant bedsore and recurrence (Ependymoma) (n=01, 01.59%). Aggressive surgical excision potentially minimizes neurologic morbidity and improved outcome except intramedullary tumors where initial treatment consists of maximum safe surgical resection or biopsy.

[Embolic stroke by thrombotic non bacterial endocarditis in an Antiphospholipid Syndrome patient]. / Accidente cerebrovascular embólica por endocarditis trombótica no bacteriana en pacientes son Síndrome Antifosfolípido.

The antiphospholipid syndrome (APS) is an acquired thrombophilia, considered a systemic autoimmune disorder. We report a patient with APS who presented multiple cerebral infarcts (stroke) as a complication of a thrombotic non bacterial endocarditis. We review the literature focused on the physiological mechanism that produce this disease and its complications. Clinical features and their prognostic value and the different therapeutic options were also studied.

Conversion to drip irrigated agriculture may offset historic anthropogenic and wildfire contributions to sediment production.

This study is an investigation into the roles of wildfire and changing agricultural practices in controlling the inter-decadal scale trends of suspended sediment production from semi-arid mountainous rivers. In the test case, a decreasing trend in suspended sediment concentrations was found in the lower Salinas River, California between 1967 and 2011. Event to decadal scale patterns in sediment production in the Salinas River have been found to be largely controlled by antecedent hydrologic conditions. Decreasing suspended sediment concentrations over the last 15years of the record departed from those expected from climatic/hydrologic forcing. Sediment production from the mountainous headwaters of the central California Coast Ranges is known to be dominated by the interaction of wildfire and large rainfall/runoff events, including the Arroyo Seco, an ~700km(2) subbasin of the Salinas River. However, the decreasing trend in Salinas River suspended sediment concentrations run contrary to increases in the watershed's effective burn area over time. The sediment source area of the Salinas River is an order of magnitude larger than that of the Arroyo Seco, and includes a more complicated mosaic of land cover and land use. The departure from hydrologic forcings on suspended sediment concentration patterns was found to coincide with a rapid conversion of irrigation practices from sprinkler and furrow to subsurface drip irrigation. Changes in agricultural operations appear to have decreased sediment supply to the Salinas River over the late 20th to early 21st centuries, obscuring the influence of wildfire on suspended sediment production.

Diurnal variability and biogeochemical reactivity of mercury species in an extreme high-altitude lake ecosystem of the Bolivian Altiplano.

Methylation and demethylation represent major transformation pathways regulating the net production of methylmercury (MMHg). Very few studies have documented Hg reactivity and transformation in extreme high-altitude lake ecosystems. Mercury (Hg) species concentrations (IHg, MMHg, Hg°, and DMHg) and in situ Hg methylation (M) and MMHg demethylation (D) potentials were determined in water, sediment, floating organic aggregates, and periphyton compartments of a shallow productive Lake of the Bolivian Altiplano (Uru Uru Lake, 3686 m). Samples were collected during late dry season (October 2010) and late wet season (May 2011) at a north (NS) and a south (SS) site of the lake, respectively. Mercury species concentrations exhibited significant diurnal variability as influenced by the strong diurnal biogeochemical gradients. Particularly high methylated mercury concentrations (0.2 to 4.5 ng L(-1) for MMHgT) were determined in the water column evidencing important Hg methylation in this ecosystem. Methylation and D potentials range were, respectively, <0.1-16.5 and <0.2-68.3 % day(-1) and were highly variable among compartments of the lake, but always higher during the dry season. Net Hg M indicates that the influence of urban and mining effluent (NS) promotes MMHg production in both water (up to 0.45 ng MMHg L(-1) day(-1)) and sediment compartments (2.0 to 19.7 ng MMHg g(-1) day(-1)). While the sediment compartment appears to represent a major source of MMHg in this shallow ecosystem, floating organic aggregates (dry season, SS) and Totora's periphyton (wet season, NS) were found to act as a significant source (5.8 ng MMHg g(-1) day(-1)) and a sink (-2.1 ng MMHg g(-1) day(-1)) of MMHg, respectively. This work demonstrates that high-altitude productive lake ecosystems can promote MMHg formation in various compartments supporting recent observations of high Hg contents in fish and water birds.

[Incidence of type 1 diabetes in Navarre, 2009-2012]. / Incidencia de la diabetes tipo 1 en Navarra, 2009-2012.

BACKGROUND: A north-south gradient for the incidence of type 1 diabetes (DM1) has been described in Europe, with higher incidence in the northern countries. The aim of this study is to describe the incidence data for DM1 in Navarre from 2009-2012, regardless of age at diagnosis, including geographical distribution and age and sex characteristics. PATIENTS AND METHODS: Prospective study, based on one primary and three secondary sources. Completeness of records was assessed, using the capture-recapture method, at 98.42%. Incidence was compared between different gender and age groups by estimating the incidence ratio using Poisson regression methods. To compare the incidence between the different geographical areas, adjustments were made to the values obtained by the indirect standardization method. RESULTS: A total of 216 cases were detected (incidence: 8.4/100,000 population/year; 95 % CI: 7.3-9.5). Incidence was higher in children than in adults, although the number of new cases was highest in those aged over 15. The age group with the highest incidence was 10 to 14 years; however, the highest percentage of patients fell in the 15 to 29-year-old group. Incidence was higher in men than in women. The incidence rates in the three southern regions were generally higher than the mean for Navarre. CONCLUSIONS: Navarre has a very high incidence of DM1 in children and adults aged 15 to 29. DM1 is more common in men and shows some geographic variability.

Uptake and translocation of metals in different parts of crop plants irrigated with contaminated water from DEPZ area of Bangladesh.

Metal contamination in arable soils and crops grown in and around an industrial area of Bangladesh were measured, and the transfer factor from soils to crops was calculated accordingly. The highest concentration was observed for Fe and the order of metal concentration was Fe > Zn > Cr > Pb > Cu > Ni > Cd in soils. Bioaccumulation and translocation of metals from roots to edible parts of the crop plants were varied for almost all elements studied. Absorption of metals was significantly more in the roots compared to other plant parts. Accumulation of all metals in the edible parts of the plants was compared with the recommended maximum tolerable levels proposed by the Joint FAO/WHO Expert Committee on Food Additives. Bioconcentration factors values based on dry weights were below one for all metals except Cu in the rice roots and decreased in the order of Cu > Zn > Fe > Pb > Ni > Cd > Cr.
