Novel sfericase protease improves amino acid digestibility of soybean meal and rapeseed meal in broiler chickens.

1. Two experiments were conducted to explore the effects of an exogenous sfericase protease on the apparent ileal nutrient digestibility of soybean meal (SBM) and rapeseed meal (RSM) in broiler chickens.2. In each experiment, a total of 256 sixteen-day-old male Cobb 500 broilers were fed one of four semi-purified experimental diets, comprising two different batches (A and B) of samples for either SBM (Exp. 1) or RSM (Exp. 2) without or with an exogenous sfericase (0 or 30,000 NFP/kg). Each experimental diet was fed to eight replicate pens of broiler chickens from 16 to 21 d of age (eight birds per cage), and ileal digesta were collected for measuring the digestibility coefficients.3. In Exp. 1, the amino acid digestibility was greater (P < 0.05) in SBM B compared with SBM A for Arg and Val, and a similar trend (P < 0.1) was observed for Tyr, Leu and Thr. Exogenous sfericase increased (P < 0.10) digestibility of most of amino acids except Gly, His and Trp. There was an interaction between SBM source and sfericase, whereby digestibility of P, N and Asp was increased by sfericase for SBM B but not for SBM A. In Exp. 2, there was no interaction (P > 0.05) between RSM source and sfericase for ileal nutrient digestibility. Digestibility was greater in RSM A compared to RSM B for all non-essential AA and most essential AA (except for Trp), while the reverse was noted for Ca and P (P < 0.05). Exogenous sfericase increased (P < 0.1) digestibility for all amino acids except Cys and Met.4. In conclusion, the current studies showed that both SBM and RSM batches influenced amino acid digestibility. Sfericase protease supplementation increased amino acid digestibility for both SBM and RSM. The digestibility effects were greater in the SBM batch with low digestibility for N and Asp which was in line with an increase in P digestibility.

Risk Factors for Surgical Site Infections Following Fasciotomy in Patients With Acute Compartment Syndrome: A Study on the February 2023 Kahramanmaras Earthquake.

INTRODUCTION: Surgical site infections (SSIs) developing after fasciotomy are difficult to treat, costly, and an important source of mortality and morbidity. This study aimed to determine the risk factors affecting the development of SSI in patients who underwent fasciotomy with the diagnosis of acute compartment syndrome (ACS) within 72 hours after two consecutive earthquakes of 7.7 and 7.6 magnitude that occurred in Kahramanmaras on February 6, 2023. METHOD: A total of 116 patients were retrospectively analyzed. Patients were divided into two groups: those who developed SSI and those who did not. In this study, variables such as basic demographic characteristics, time of fasciotomy, center performing fasciotomy, type of wound closure, affected extremity, concomitant renal failure, hyperbaric oxygen (HBO) therapy, blood creatine kinase (CK) level were examined. RESULTS: Of 116 patients, 58 (50%) had SSI. It was statistically observed that patients who underwent treatment with vacuum-assisted closure (VAC), those who underwent primary closure with the shoelace method, those who went into renal failure, and those whose fasciotomy was performed in an earthquake zone had a higher incidence of SSI (p<0.001). Blood CK level above 17.839 seemed to be a risk factor according to receiver operating characteristic (ROC) analysis (P<0.01). Age (p=0.193), gender (p=0.125), fasciotomy time (p=0.843), lower extremity (p=0.234), upper extremity (p=0.806), and HBO treatment (p=0.56) were not associated with SSI. Infection was found to be a significant risk factor for amputation (p<0.001). CONCLUSION: The use of VAC as a wound closure technique for SSI after fasciotomy in patients who developed ACS due to the earthquake, the presence of renal failure in the patients, and performing fasciotomy in the earthquake zone were independent risk factors. A blood CK level above 17.839 was also determined as a risk factor, but the confidence interval was found to be low.

Factors associated with seizure severity among children with epilepsy in Northern Nigeria.

Objective: To describe how seizure severity in children with epilepsy may be affected by certain socio-demographic and clinical variables. Design: A cross-sectional study. Setting: At the Abubakar Tafawa Balewa University Teaching Hospital, Bauchi, Nigeria. Participants: Sixty children and adolescents who were being followed up for seizure disorder at the child neurology clinic. Intervention: Information on socio-demographic characteristics was obtained with a questionnaire, details of neurological co-morbidities were extracted from the participants' records, and seizure severity was assessed with the National Hospital Seizure Severity Score 3 tool. Main Outcome Measure: Chi-square test was used to establish the relationship between categorical variables, while the Independent t-test was used in describing the differences between means. Simple linear regression was calculated to assess the predictability of seizure severity. Result: The median age was ten years (IQR = 6-13 years), with a male dominance (1.5:1). The Seizure Severity Score (SSS) ranged between 3 and 24 units, with a mean of 12.22 ± 4.29 units. The only characteristic that had a significant association with SSS on bivariate analysis was the "presence of co-morbidities" (p=0.019). A simple linear regression revealed that the presence of a neurological co-morbidity predicted an increase in the SSS by 2.67 units. [R2 = 0.091, F (1, 58)= 5.837, p = 0.019. ß = 2.67, t= 2.42, p= 0.019.]. Conclusion: This study shows that neurological co-morbidities predict worsening seizure severity. This knowledge may influence prognostication and the charting of a treatment trajectory. Funding: No external funding.

Evaluation of the efficacy of a novel phytase in short-term digestibility and long-term egg production studies with laying hens.

Three independent trials were conducted to evaluate the efficacy of a novel phytase in laying hens. Trial 1 used a total of 90 laying hens (Lohmann Brown, 33-wk-old) fed either a negative control (NC) diet with 0.09% non-phytate P (NPP) or NC supplemented with 187.5 or 375 FYT phytase/kg feed for 4 d before collection of excreta and ileal digesta to measure ileal digestibility and retention of Ca and P. In trial 2 and 3, a total of 108 laying hens (Hy Line Brown, 25-wk-old) and 360 hens (Lohman Brown, 25-wk-old) were used, respectively. In both trials, the hens were randomly assigned to 3 dietary treatments: NC with 0.1% NPP, positive control (PC) and NC plus 187.5 FYT phytase/kg feed, the experimental diets were fed for 12 wk, and egg production and bone mineralization were measured. The results showed that the ileal digestibility of P increased both linearly (P = 0.012) and quadratically (P = 0.01) with increasing supplementation of phytase in trial 1. In trial 2, phytase supplementation significantly improved egg production, egg weight, and feed conversion ratio and reduced the percentage of broken eggs during the overall trial duration compared with NC. In trial 3, phytase significantly improved egg production, egg weight, and feed intake and reduced the percentage of broken eggs during the entire trial duration. In addition, percentage and weight of bone Ca and P increased significantly with added phytase. In trial 2 and 3, there was no significant difference between PC and the phytase treatment. In conclusion, the novel phytase significantly increased the ileal digestibility of P in a short-term digestibility study and improved egg production and bone mineralization in a 12-wk laying cycle. Ileal digestibility of P rather than P retention in short-term digestibility studies as well as egg production and whole tibia mineralization in long-term studies should be measured to demonstrate the efficacy of phytase in laying hens.

Impact of environmental factors on the spread of dengue fever in Sri Lanka.

Dengue fever is a mosquito-borne viral disease caused by the dengue virus of the Flaviviridae family and is responsible for colossal health and economic burden worldwide. This study aimed to investigate the effect of environmental, seasonal, and spatial variations on the spread of dengue fever in Sri Lanka. The study used secondary data of monthly dengue infection and the monthly average of environmental parameters of 26 Sri Lankan regions from January 2015 to December 2019. Besides the descriptive measurements, Kendall's tau_b, Spearman's rho, and Kruskal-Wallis H test have been performed as bivariate analyses. The multivariate generalized linear negative binomial regression model was applied to determine the impacts of meteorological factors on dengue transmission. The aggregate negative binomial regression model disclosed that precipitation (odds ratio: 0.97, p < 0.05), humidity (odds ratio: 1.05, p < 0.01), and air pressure (odds ratio: 1.46, p < 0.01) were significantly influenced the spread of dengue fever in Sri Lanka. The bioclimatic zone is the vital factor that substantially affects the dengue infection, and the wet zone (odds ratio: 6.41, p < 0.05) was more at-risk than the dry zone. The climate season significantly influenced dengue fever transmission, and a higher infection rate was found (odds ratio: 1.46, p < 0.01) in the northeast monsoon season. The findings of this study facilitate policymakers to improve the existing dengue control strategies focusing on the meteorological condition in the local as well as global perspectives.

Vitamin D and bone mineral status of newborn-maternal pair delivering at a tertiary hospital in Nigeria.

BACKGROUND: Vitamin D plays a vital role in the maintenance of bone health. The fetuses and exclusively breastfed neonates depend on maternal vitamin D store to meet their need. Widespread vitamin D deficiency among pregnant women have been reported with adverse fetal outcome. Nigeria lacks guideline on Vitamin D supplementation in pregnancy and infancy due to the paucity of data. We thus determined serum vitamin D of delivering mothers and their offsprings and other indicators of bone mineral health. AIMS: This study aimed to determine serum Vitamin D and other indicators of bone mineral health of delivering mothers and their offspring. MATERIAL AND METHOD: A cross-sectional study of delivering mothers and their newborns recruited consecutively until the minimal sample size was reached. Relevant information was obtained on a questionnaire. Maternal and cord serum vitamin D, calcium, albumin, phosphate, and alkaline phosphatase were determined. Data management was done using SPSS version 16.0. RESULTS: Of the 84 newborn-mother pairs studied, 17 (20.2%) of the mothers were Vitamin D deficient and 23 (27.4%) insufficient. Seven (8.3%) of the mothers were hypocalcaemic and 3 (3.6%) hypophosphataemic, while 19 (22.6%) had elevated alkaline phosphatase. Only 15 (17.9%) of the neonates were vitamin D insufficient and none of them was vitamin D deficient, hypocalcaemic, hypophosphataemic nor had elevated alkaline phosphatase. There was strong positive correlation between cord and maternal blood vitamin D level (r = 0.740, P = < 0.001). CONCLUSION: Vitamin D deficiency and insufficiency is high among pregnant women in Maiduguri while insufficiency is common among the neonates. We recommend vitamin D supplementation to pregnant women and newborns in Maiduguri.

Effects of N-Acetylcysteine and N-Acetylcysteine Amide on Erythrocyte Deformability and Oxidative Stress in a Rat Model of Lower Extremity Ischemia-Reperfusion Injury.

N-acetylcysteine (NAC) is an antioxidant which works as a free radical scavenger and antiapoptotic agent. N-acetylcysteine-amide (NACA) is a modified form of NAC containing an amide group instead of a carboxyl group of NAC. Our study aims to investigate the effectiveness of these two substances on erythrocyte deformability and oxidative stress in muscle tissue. Materials and Methods. A total of 24 Wistar albino rats were used in our study. The animals were randomly divided into five groups as control (n: 6), ischemia (n: 6), NAC (n: 6), and NACA (n: 6). In the ischemia, NAC, and NACA groups, 120 min of ischemia and 120 min of reperfusion were achieved by placing nontraumatic vascular clamps across the abdominal aorta. The NAC and NACA groups were administered an injection 30 min before ischemia (100 mg/kg NAC; 100 mg/kg NACA; intravenous). Blood samples were taken from the animals at the end of the ischemic period. The lower extremity gastrocnemius muscle was isolated and stored at -80 degrees to assess the total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values and was analyzed. Results. The erythrocyte deformability index was found to be statistically significantly lower in rats treated with NAC and NACA before ischemia-reperfusion compared to the groups that received only ischemia-reperfusion. In addition, no statistically significant difference was found between the control group and the NAC and NACA groups. The groups receiving NAC and NACA before ischemia exhibited higher total antioxidative status and lower total oxidative status while the oxidative stress index was also lower. Conclusion. The results of our study demonstrated the protective effects of NAC and NACA on erythrocyte deformability and oxidative damage in skeletal muscle in lower extremity ischemia-reperfusion. NAC and NACA exhibited similar protective effects on oxidative damage and erythrocyte deformability.

Incidence, types and outcomes of sternal wound infections after cardiac surgery in Saudi Arabia. A retrospective medical chart review.

OBJECTIVES: To determine the incidence, types, risk factors, identify organisms, and assess outcomes of surgical wound infections (SWIs) after cardiac surgery at a tertiary hospital in Riyadh, Saudi Arabia. Methods: This historical cohort study reviewed the chart of  patients who underwent cardiac surgery at King Khalid University Hospital, Riyadh, Saudi Arabia between January 2009 and December 2014. The proforma contained personal data, comorbidities, type of surgery, microbiological analysis, and management outcomes. Results: A total of 1241 patients were enrolled in the study comprising 1,032 (83.2%) men and 209 (16.8%) women. Forty (3.2%) patients developed SWI, of which 32 (2.5%) were superficial and 8 (0.7%) were deep. Gender, obesity, diabetes mellitus, non-use of statins, and coronary artery bypass graft (CABG) surgery were not significant predictors of infection in the study. Methicillin-susceptible Staphylococcus aureus was isolated predominantly in 45%, followed by Klebsiella and Pseudomonas species. Methicillin-resistant Staphylococcus aureus, Enterococcus faecium, and extended ß-lactamase-producing gram-negative organisms were pathogens isolated in last 3 years of the review.  Simple and vacuum assisted closure therapies led to complete resolution in 32 (80%) patients, while 8 (20%) developed sternal osteomyelitis. All patients survived except one with a deep SWI who died of uncontrolled sepsis.  Conclusion: Despite the low incidence of postoperative SWIs, the risk of sternal osteomyelitis development persists. Meticulous choice of CABG components and appropriate postoperative management, especially detecting early signs of SWI could contribute to lower its incidence and complications.

A meta-analysis on the effect of canthaxanthin on egg production in brown egg layers.

A meta-analysis was conducted to evaluate the effect of the carotenoid canthaxanthin on production performance in layer hens. The data set contained 576 performance measurements from 34 trials. The trials were all conducted according to a similar experimental protocol from 1997 to 2012. The age of the animals ranged from 21 to 65 weeks. The experimental diets were predominantly wheat/SBM based, fed in mash form ad libitum. Depending on the trial and the treatment group considered, canthaxanthin supplementation was in the range of 0 to 8 mg/kg of feed.Using a linear mixed model regression applied to all 34 trials simultaneously, significant dose-dependent increases were found in egg yolk mass (+0.53% per ppm of canthaxanthin inclusion in the feed, P < 0.001), in egg mass (+0.47% per ppm, P = 0.0132), egg weight (+0.17% per ppm, P = 0.046), and in feed intake (+0.32% per ppm, P = 0.0054). A numerical increase was found in egg production (+0.28%, P = 0.14). The FCR decreased numerically (-0.24% per ppm, P = 0.36). The deposition of canthaxanthin in the egg yolk was 2.25 ppm per ppm of canthaxanthin in the feed (P < 0.001). It is concluded that in addition to egg yolk pigmentation, antioxidant effect, enhanced reproduction, and immune-modulation, canthaxanthin can significantly increase egg mass, thereby enhancing the productivity of the flock. Mechanisms relating to carotenoid metabolism and functions in avian species are a new research area that will require further investigation to explain the observed effects.

Identification and molecular characterization of Echinococcus granulosus from domestic goat in Chittagong, Bangladesh.

The tapeworm Echinococcus granulosus causes cystic echinococcosis (CE) in human and many domestic animals worldwide including Bangladesh. The parasite has significant public health importance in the country and no in-depth study has been conducted to determine this cestode in either human or animals. The aim of present study was to evaluate genotype of E. granulosus isolated from domestic goats reared in Chittagong, Bangladesh using DNA based tools. Partial gene fragment of 12S rRNA gene and Cytochrome oxidase 1 gene were accomplished by PCR followed by sequencing and phylogenetic analyses. A total of 19 hydatid cyst samples were collected from 385 goats from several local slaughterhouses located in Chittagong. The rates of fertile hydatid cysts were found as high as 57.89% while remaining cysts were found non-viable and sterile. Genomic DNA was extracted from germinal membrane and/or protoscolices for PCR assay. Sequence similarity based on BLAST search revealed variable prevalence of E. granulosus genotypes such as G1 (68.42%) and G1/G3 complex (31.58%) which is reported for the first time in the country. This result indicates common sheep strain G1 is the dominant subtype of E. granulosus in this region. The study generated six sequences of which four were aligned with G1 common sheep strain and two were aligned with G3 strain (commonly referred as Buffalo strain). Phylogenetic analysis of 12S rRNA gene and Cytochrome oxidase 1 gene also indicated that common sheep strain (G1) and Buffalo strain (G3) are circulating among domestic goats in Chittagong region of Bangladesh.

Results of an international phosphorus digestibility ring test with broiler chickens.

The objective of this ring test was to investigate the prececal phosphorus (P) digestibility of soybean meal (SBM) in broiler chickens using the trial protocol proposed by the World's Poultry Science Association. It was hypothesized that prececal P digestibility of SBM determined in the collaborating stations is similar. Three diets with different inclusion levels of SBM were mixed in a feed mill specialized in experimental diets and transported to 17 collaborating stations. Broiler chicks were raised on commercial starter diets according to station-specific management routine. Then they were fed the experimental diets for a minimum of 5 d before content of the posterior half of the ileum was collected. A minimum of 6 experimental replicates per diet was used in each station. All diets and digesta samples were analyzed in the same laboratory. Diet, station, and their interaction significantly affected (P < 0.05) the prececal digestibility values of P and calcium of the diets. The prececal P digestibility of SBM was determined by linear regression and varied among stations from 19 to 51%, with significant differences among stations. In a subset of 4 stations, the prececal disappearance of myo-inositol 1,2,3,4,5,6-hexakis (dihydrogen phosphate)-P; InsP6-P) also was studied. The prececal InsP6-P disappearance correlated well with the prececal P digestibility. We hypothesized that factors influencing InsP6 hydrolysis were main contributors to the variation in prececal P digestibility among stations. These factors were probably related to the feeding and housing conditions (floor pens or cages) of the birds in the pre-experimental phase. Therefore, we suggest that the World's Poultry Science Association protocol for the determination of digestible P be should extended to the standardization of the pre-experimental period. We also suggest that comparisons of P digestibility measurements among studies are made only with great caution until the protocol is more refined.

Development of a Simple, Peripheral-Blood-Based Lateral-Flow Dipstick Assay for Accurate Detection of Patients with Enteric Fever.

Enteric fever is a systemic infection caused by typhoidal strains of Salmonella enterica and is a significant cause of mortality and morbidity in many parts of the world, especially in resource-limited areas. Unfortunately, currently available diagnostic tests for enteric fever lack sensitivity and/or specificity. No true clinically practical gold standard for diagnosing patients with enteric fever exists. Unfortunately, microbiologic culturing of blood is only 30 to 70% sensitive although 100% specific. Here, we report the development of a lateral-flow immunochromatographic dipstick assay based on the detection of Salmonella enterica serovar Typhi (S Typhi) lipopolysaccharide (LPS)-specific IgG in lymphocyte culture secretion. We tested the assay using samples from 142 clinically suspected enteric fever patients, 28 healthy individuals residing in a zone where enteric fever is endemic, and 35 patients with other febrile illnesses. In our analysis, the dipstick detected all blood culture-confirmed S Typhi cases (48/48) and 5 of 6 Salmonella enterica serovar Paratyphi A blood cultured-confirmed cases. The test was negative in all 35 individuals febrile with other illnesses and all 28 healthy controls from the zone of endemicity. The test was positive in 19 of 88 individuals with suspected enteric fever but with negative blood cultures. Thus, the dipstick had a sensitivity of 98% compared to blood culture results and a specificity that ranged from 78 to 100% (95% confidence interval [CI], 70 to 100%), depending on the definition of a true negative. These results suggest that this dipstick assay can be very useful for the detection of enteric fever patients especially in regions of endemicity.

O-Specific Polysaccharide-Specific Memory B Cell Responses in Young Children, Older Children, and Adults Infected with Vibrio cholerae O1 Ogawa in Bangladesh.

Cholera caused by Vibrio cholerae O1 confers at least 3 to 10 years of protection against subsequent disease regardless of age, despite a relatively rapid fall in antibody levels in peripheral blood, suggesting that memory B cell responses may play an important role in protection. The V. cholerae O1-specific polysaccharide (OSP) component of lipopolysaccharide (LPS) is responsible for serogroup specificity, and it is unclear if young children are capable of developing memory B cell responses against OSP, a T cell-independent antigen, following cholera. To address this, we assessed OSP-specific memory B cell responses in young children (2 to 5 years, n = 11), older children (6 to 17 years, n = 21), and adults (18 to 55 years, n = 28) with cholera caused by V. cholerae O1 in Dhaka, Bangladesh. We also assessed memory B cell responses against LPS and vibriocidal responses, and plasma antibody responses against OSP, LPS, and cholera toxin B subunit (CtxB; a T cell-dependent antigen) on days 2 and 7, as well as days 30, 90, and 180 after convalescence. In all age cohorts, vibriocidal responses and plasma OSP, LPS, and CtxB-specific responses peaked on day 7 and fell toward baseline over the follow-up period. In comparison, we were able to detect OSP memory B cell responses in all age cohorts of patients with detectable responses over baseline for 90 to 180 days. Our results suggest that OSP-specific memory B cell responses can occur following cholera, even in the youngest children, and may explain in part the age-independent induction of long-term immunity following naturally acquired disease.

Correlation of the Serum Level of Carcinoembryonic Antigen and Prolactin with Different Stages of Colorectal Carcinoma According to Dukes' Staging.

Carcinoembryonic antigen (CEA) is well established tumor marker for colorectal cancers worldwide. Recent studies show that serum prolactin level is also raised in colorectal cancers. The purpose of the study is to evaluate the correlation of serum CEA and Prolactin with Dukes' staging of colorectal carcinomas. Between January 2013 and June 2013, Serum CEA and Serum Prolactin were measured by radioimmunoassay from 103 patients who were histopathologically diagnosed as colorectal carcinomas. Evaluation of the stages of the colorectal cancers was done on the basis of preoperative investigations and postoperative histopathology and correlated with Preoperative Serum CEA and Serum Prolactin. Results were presented as median value, range and percentage. Male to female ratio was 1.4:1 with median age of 42.26 years (range 17-78 years). Most of the patients in this series presented with carcinoma rectum (42%). Most of the patients (52%) were found in Dukes' stage C and 27% and 15% cases were found as Dukes' stage B and Dukes' stage D respectively. Stage of the disease is directly proportionate to percentage of the patient with high serum prolactin except early stage (Dukes' A-50%, Dukes' B-28.6%, Dukes' C-33.3% & Dukes' D-46.7%). Similarly serum CEA level is directly proportionate to tumor stage (Dukes' A-0%, Dukes' B-32%, Dukes' C-40.7% & Dukes' D-74.7%). A preoperative high serum CEA value suggests advanced disease either locally or with distant metastasis. In contrast preoperative high serum prolactin (hyperprolactinaemia) did not suggest advanced disease as it can be elevated even in early stage of disease. Serum CEA and Serum Prolactin both are valuable tumor markers but serum CEA could not be replaced by serum Prolactin. Serum Prolactin may be a helpful marker in earlier stages of the colorectal cancer.

Simultaneous inclusion of sorghum and cottonseed meal or millet in broiler diets: effects on performance and nutrient digestibility.

Two experiments were conducted to investigate the use of sorghum, cottonseed meal and millet in broiler diets and their interaction when they are used simultaneously. In Experiment 1, a corn-soybean meal control diet was compared with eight experimental treatments based on low tannin sorghum (S30, S45 and S60), cottonseed meal (CM15, CM40) or both ingredients included in the same diet (S30/CM40, S45/CM25 and S60CM15). Results showed that BW gain was not affected by the inclusion of sorghum or cottonseed meal. However, feed intake tended to be affected by the cereal type with the highest values with sorghum-based diets. Feed conversion ratio increased (P<0.001) with sorghum-based diets compared with the control diet, whereas a combination of cottonseed meal and sorghum in the same diet did not affect the feed conversion ratio. Significant differences (P<0.001) were observed in apparent ileal digestibility (%) of protein and energy with the cottonseed meal and sorghum/cottonseed meal-based diets having lower protein and energy digestibility compared with corn-based diets. In Experiment 2, a control diet was compared with six diets in which corn was substituted at 60%, 80% or 100% by either sorghum or millet and other three diets with simultaneous inclusion of these two ingredients (S30/M30, S40/M40, S50/M50). Single or combined inclusion of sorghum and millet resulted in similar feed intake and growth performance as the control diet. Apparent ileal digestibility of protein and energy was higher with millet-based diets (P<0.001). Total tract digestibility of protein in sorghum and millet-based diets tended to decrease linearly with the increasing level of substitution. Sorghum-based diets resulted in lower total tract digestibility of fat compared with millet and sorghum/millet-based diets (P<0.001). Higher total tract digestibility of starch were obtained with the control diet and millet-based diets compared with the sorghum-based treatments. Results of the two experiments suggest that broiler growth performance was not affected by the dietary level of sorghum, millet or cottonseed meal. Nutrient digestion can, however, be affected by these feed ingredients.

Predictors and risk factors for the intestinal shedding of Escherichia coli O157 among working donkeys (Equus asinus) in Nigeria.

OBJECTIVES: Escherichia coli are an important group of bacteria in the normal gastrointestinal system but can sometimes cause infections in domestic animals and man. Donkeys are routinely used as multipurpose animal but details of burdens of potentially infectious bacteria associated with it are limited. The prevalence and associations between intestinal shedding of E. coli O157 and animal characteristics and management factors were studied among 240 randomly selected working donkeys in north-western Nigeria. DESIGN: Four local government areas, of Sokoto State in north-western Nigeria were recruited in this study. A multistage randomised cluster design was used to select subjects and donkey owners within selected zones. Confirmation of infection was based on bacterial culture, isolation and biochemical test for E. coli O157 from faecal samples. RESULTS: Of the total bacteria isolated, 203 of the 329 (61.70 per cent) were E. coli, 76 of which was E. coli serotype O157. A multivariable logistic regression model was used to examine the relation between intestinal shedding of E. coli O157 and selected variables. The analysis yielded five potential predictors of shedding: soft faeces in donkeys, Akaza and Fari ecotypes of donkey were positive predictors while maize straw as feed and sampling during the cold dry period were negative predictors. CONCLUSIONS: This study concludes that controlling intestinal shedding of E. coli O157 among working donkeys in Nigeria is possible using the identified predictors in planning appropriate interventions to reduced human risk of infection.

Inclusion of sorghum, millet and cottonseed meal in broiler diets: a meta-analysis of effects on performance.

A meta-analysis was conducted (i) to evaluate broiler response to partial or total substitution of corn by sorghum and millet and (ii) to determine the effect of soybean meal replacement by cottonseed meal in broiler diet. The database included 190 treatments from 29 experiments published from 1990 to 2013. Bird responses to an experimental diet were calculated relative to the control (Experimental-Control), and were submitted to mixed-effect models. Results showed that diets containing millet led to similar performance as the corn-based ones for all parameters, whereas sorghum-based diets decreased growth performance. No major effect of the level of substitution was observed with millet or cottonseed meal. No effect of the level of substitution of sorghum on feed intake was found; however, growth performance decreased when the level of substitution of corn by sorghum increased. Cottonseed meal was substituted to soybean meal up to 40% and found to increase feed intake while reducing growth performance. Young birds were not more sensitive to these ingredients than older birds since there was no negative effect of these ingredients on performance in the starter phase. Results obtained for sorghum pointed out the necessity to find technological improvements that will increase the utilization of these feedstuffs in broiler diet. An additional work is scheduled to validate these statistical results in vivo and to evaluate the interactions induced with the simultaneous inclusions of sorghum, millet and cottonseed meal in broiler feeding.

Cervical premalignant lesions and their management.

Cervical cancer is the tenth most common cancer in women in developed countries that have national screening programs, while it is in the second line in underdeveloped countries. According to Ministry of Health registry data, cervical cancer is the eighth most common cancer among female cancers in Turkey. Today, the most effective screening for cervical cancer is to obtain smears from the cervix. Therefore, periodic screening programs are of great importance in identifying preinvasive lesions to prevent their progression to invasive cancer. Today, with the use of human papilloma virus (HPV) vaccine, screening programs have brought new insights into the prevention of cervical cancer. Management of preinvasive lesions has to be known by each obstetrics and gynecology specialist. Redundant procedures and treatments can be avoided by directing patients correctly at this step. Cancer phobia should not be created. Ablative or destructive treatments should not be done without histological diagnosis; hysterectomy, which has an equal risk of recurrence, should not be recommended.

Atypical presentation of primary giant nasal septal mucopyocele.

Mucoceles are expansile, encapsulated, benign cystic lesions with the potential for adjacent bony remodeling and resorption. Previous nasal surgery, recurrent infections, allergies, and facial traumas are all possible causes of mucoceles involving mainly paranasal sinuses. When the mucocele is infected, it is referred to as mucopyocele. Nasal septal mucoceles seen in only very seldom cases might develop from pneumatized and infected nasal septa. In the current article, we present an interesting primary giant septal mucopyocele that destroys all paranasal cells as a tumoral lesion. The perpendicular plate of ethmoidal bone, vomer, and bilateral anterior and posterior ethmoidal cells were destroyed by mucopyocele. The nasal cavity was totally obstructed by lesions on both sides. On the left side, the lesion also eroded the left lateral nasal wall causing external swelling at the medial canthal region. This is the first case of a giant septal mucopyocele of its kind in the literature. Although nasal septal mucocele is very rare, it should be considered in differential diagnosis of intranasal masses.

Biochemical analysis of two varieties of water chestnuts (Trapa sp.).

In this study, two varieties (Green and red) of water chestnuts (Trapa sp.) have been selected for their biochemical analysis as well as nutrient composition using standard methods. The proximate composition of green water chestnuts revealed moisture 62.5, ash 1.04, crude fiber 2.13%, total soluble sugar 0.92%, reducing sugar 0.33%, non-reducing sugar 0.59%, starch 8.7%, lipid 0.84%. One hundred gram of green variety contained water soluble protein 0.275 mg, beta-Carotene 60 microg, vitamin-C 1.1 mg and total phenol 0.5 mg. The minerals contents of green variety were potassium 5.22%, sodium 0.64%, calcium 0.25%, phosphorus 6.77%, sulpher 0.38%, and iron, copper, manganese and zinc 200, 430, 90 and 600 ppm, respectively. The red variety contained moisture 62.7%, ash 1.30%, crude fiber 2.27%, total soluble sugar 0.90%, reducing sugar 0.30%, non-reducing sugar 0.60%, starch 8.2%, lipid 0.83%. The red variety contained water soluble protein 0.251 mg, beta-Carotene 92 microg, vitamin-C 0.9 mg and total phenol 0.60 mg per 100 g. The red variety contained potassium 5.32%, sodium 0.59%, calcium 0.26% phosphorus 6.77%, sulpher 0.32%, Iron 200 ppm, copper 450 ppm, manganese 110 ppm and zinc 650 ppm. The free amino acids, glutamic acid, tryptophan, tyrosine, alanine, lysine and leucine were commonly found in both varieties. In addition, green and red variety contained cysteine, arginine and proline and glutamine and asparagines, respectively. Thus, the present study sheds light on the nutrient contents of the two varieties of water chestnuts and suggests that water chestnuts may play a crucial role in human nutrition.
