    Purpose: To investigate the toxicity, clinical outcome and anthelmintic effects of M. pudica in vitro and in vivo.Methods: Dried leaves of M. pudica were extracted using 70 % methanol cold maceration method. Acute toxicity inquiry was evaluated using Lorke’s method. Anthelmintic effects were investigated in vitro using the egg hatch assay and in vivo using Heligmosomoides bakeri experimentally infected adult albino mice. Coprological and haematological parameters were recorded during the experiment while the serological analysis and post mortem worm burden were assessed at the conclusion of the research.Results: No mortality was recorded in oral acute toxicity test up to a dose of 5000 mg/kg. A probit-log analysis of the percentage egg hatch of the extract and albendazole gave lethal concentration 50 (LC50) values of 1.160 and -1.042, respectively. A reduction in worm count was observed in all the extracttreated groups post mortem, with the maximum extract group having the least worm count (p < 0.05). Treatment with extract resulted in improvement in the haematological parameters. Serum chemistry revealed no significant differences (p > 0.05) in alanine aminotransferase and blood urea nitrogen in all groups. However, a dose-dependent increases in the total protein and albumin was observed.Conclusion: These results show that although M. pudica has weak anthelmintic effects compared to albendazole (standard  anthelmintic), in vivo and in vitro, at the doses used in this study, nonetheless, it reduces worm burden and improves haematologic parameters, serum total protein, albumin and overall weight gain of the treated mice. Thus, increased doses may be effective in anthelmintic chemotherapy. Keywords: Mimosa pudica, Anthelmintic, Toxicity, Heligmosomoides bakeri, Ethnoveterinary medicine, Anthelminti

    Cultivated groundnut or peanut (Arachis hypogaea), an allopolyploid oilseed crop with a large and complex genome, is one of the most nutritious food. This crop is grown in more than 100 countries, and the low productivity has remained the biggest challenge in the semiarid tropics. Recently, the groundnut research community has witnessed fast progress and achieved several key milestones in genomics research including genome sequence assemblies of wild diploid progenitors, wild tetraploid and both the subspecies of cultivated tetraploids, resequencing of diverse germplasm lines, genome-wide transcriptome atlas and cost-effective high and low-density genotyping assays. These genomic resources have enabled high-resolution trait mapping by using germplasm diversity panels and multi-parent genetic populations leading to precise gene discovery and diagnostic marker development. Furthermore, development and deployment of diagnostic markers have facilitated screening early generation populations as well as marker-assisted backcrossing breeding leading to development and commercialization of some molecular breeding products in groundnut. Several new genomics applications/technologies such as genomic selection, speed breeding, mid-density genotyping assay and genome editing are in pipeline. The integration of these new technologies hold great promise for developing climate-smart, high yielding and more nutritious groundnut varieties in the post-genome era

    Background: Labor induction methods are continuously evolving to ensure safer and more effective outcomes for both mother and neonate. The present study aimed to assess the effectiveness and safety of combined use of misoprostol with intracervical catheter for labor induction. Methods: This single-blinded, parallel-group randomized control trial conducted at Shaheed Suhrawardy Medical College, Dhaka, Bangladesh, included 200 women with term gestation and Bishop score ≤6. Participants were divided into two groups: the intervention group (group B) received misoprostol juice and Foley’s catheter, while the control group (group A) received misoprostol in the posterior fornix. Results: In Group A, 58% had vaginal deliveries, while in Group B, 65% had vaginal deliveries. Group B experienced a longer mean length of labor in the 1st stage (13.25±1.095) compared to Group A (12.98±1.982, p=0.008). The 3rd stage was shorter for Group B (10.00±0.000) than Group A (12.02±2.469, p<0.001). The most common induction reason was labor pain with an unfavorable cervix (31 in Group A and 33 in Group B). Group B had a higher percentage of inductions at less than 12 hours and a lower percentage at more than 24 hours. Neonatal outcomes were generally better for Group B. The Cox regression hazard model showed a lower likelihood of positive outcomes in Group B (hazard ratio 0.337, 95% CI 0.243-0.469, p=0.000), indicating a statistically significant difference between the groups. Conclusions: The combined use of misoprostol with Foley’s catheter for labor induction is safe and effective, resulting in shorter labor duration and higher rates of vaginal delivery compared to misoprostol alone

    PurposeOsteogenesis imperfecta (OI) predisposes people to recurrent fractures, bone deformities, and short stature. There is a lack of large-scale systematic studies that have investigated growth parameters in OI.MethodsUsing data from the Linked Clinical Research Centers, we compared height, growth velocity, weight, and body mass index (BMI) in 552 individuals with OI. Height, weight, and BMI were plotted on Centers for Disease Control and Prevention normative curves.ResultsIn children, the median z-scores for height in OI types I, III, and IV were -0.66, -6.91, and -2.79, respectively. Growth velocity was diminished in OI types III and IV. The median z-score for weight in children with OI type III was -4.55. The median z-scores for BMI in children with OI types I, III, and IV were 0.10, 0.91, and 0.67, respectively. Generalized linear model analyses demonstrated that the height z-score was positively correlated with the severity of the OI subtype (P < 0.001), age, bisphosphonate use, and rodding (P < 0.05).ConclusionFrom the largest cohort of individuals with OI, we provide median values for height, weight, and BMI z-scores that can aid the evaluation of overall growth in the clinic setting. This study is an important first step in the generation of OI-specific growth curves

    <p>Abstract</p> <p>Background</p> <p>Although a leading cause of visual impairment and a treatable cause of blindness globally, the pattern of refractive errors in many populations is unknown. This study determined the pattern of refractive ocular conditions, reasons for spectacles renewal and the effect of correction on refractive errors in a resource-limited community.</p> <p>Methods</p> <p>A retrospective review of case records of 1,413 consecutive patients seen in a private optometry practice, Nigeria between January 2006 and July 2007.</p> <p>Results</p> <p>A total number of 1,216 (86.1%) patients comprising of (486, 40%) males and (730, 60%) females with a mean age of 41.02 years SD 14.19 were analyzed. The age distribution peaked at peri-adolescent and the middle age years. The main ocular complaints were spectacles loss and discomfort (412, 33.9%), blurred near vision (399, 32.8%) and asthenopia (255, 20.9%). The mean duration of ocular symptoms before consultation was 2.05 years SD 1.92. The most common refractive errors include presbyopia (431, 35.3%), hyperopic astigmatism (240, 19.7%) and presbyopia with hyperopia (276, 22.7%). Only (59, 4.9%) had myopia. Following correction, there were reductions in magnitudes of the blind (VA<3/60) and visually impaired (VA<6/18-3/60) patients by (18, 58.1%) and (89, 81.7%) respectively. The main reasons for renewal of spectacles were broken lenses/frame/scratched lenses/lenses' falling off (47, 63.4%).</p> <p>Conclusions</p> <p>Adequate correction of refractive errors reduces visual impairment and avoidable blindness and to achieve optimal control of refractive errors in the community, services should be targeted at individuals in the peri-adolescent and the middle age years.</p

    Which resources should be used to identify RCT/CCTs for systematic reviews: a systematic review

    BACKGROUND: Systematic reviewers seek to comprehensively search for relevant studies and summarize these to present the most valid estimate of intervention effectiveness. The more resources searched, the higher the yield, and thus time and costs required to conduct a systematic review. While there is an abundance of evidence to suggest how extensive a search for randomized controlled trials (RCTs) should be, it is neither conclusive nor consistent. This systematic review was conducted in order to assess the value of different resources to identify trials for inclusion in systematic reviews. METHODS: Seven electronic databases, four journals and Cochrane Colloquia were searched. Key authors were contacted and references of relevant articles screened. Included studies compared two or more sources to find RCTs or controlled clinical trials (CCTs). A checklist was developed and applied to assess quality of reporting. Data were extracted by one reviewer and checked by a second. Medians and ranges for precision and recall were calculated; results were grouped by comparison. Meta-analysis was not performed due to large heterogeneity. Subgroup analyses were conducted for: search strategy (Cochrane, Simple, Complex, Index), expertise of the searcher (Cochrane, librarian, non-librarian), and study design (RCT and CCT). RESULTS: Sixty-four studies representing 13 electronic databases met inclusion criteria. The most common comparisons were MEDLINE vs. handsearching (n = 23), MEDLINE vs. MEDLINE+handsearching (n = 13), and MEDLINE vs. reference standard (n = 13). Quality was low, particularly for the reporting of study selection methodology. Overall, recall and precision varied substantially by comparison and ranged from 0 to 100% and 0 to 99%, respectively. The trial registries performed the best with median recall of 89% (range 84, 95) and median precision of 96.5% (96, 97), although these results are based on a small number of studies. Inadequate or inappropriate indexing was the reason most cited for missing studies. Complex and Cochrane search strategies (SS) performed better than Simple SS. CONCLUSION: Multiple-source comprehensive searches are necessary to identify all RCTs for a systematic review, although indexing needs to be improved. Although trial registries demonstrated the highest recall and precision, the Cochrane SS or a Complex SS in consultation with a librarian are recommended. Continued efforts to develop CENTRAL should be supported
