Oral misoprostol solution in comparison to vaginal misoprostol for induction of labour in a randomized controlled trial
Background: With more than 15% of all gravid women requiring prostaglandins in cervical ripening and labour induction. However, evidence is not clear about the preferred route or dose of the drug. So, this study was designed with objectives to compare the induction delivery interval and safety of titrated oral misoprostol solution with vaginal misoprostol for labour induction in term primigravida women.Methods: This randomized controlled clinical trial was conducted on a total of 100 patients randomly selected among primigravida at term women undergoing induction of labour for obstetric or medical indication for labour induction in Ain Shams University Maternity Hospital. They were divided into two Groups: Group I: patients undergoing induction of labour using misoprostol oral solution and Group II: patients undergoing induction of labour using vaginal misoprostol.Results: Oral misoprostol solution has less induction delivery duration and less side effects than vaginal misoprostol. The induction-delivery time with the oral route compared to the vaginal one (15.2 versus 20.3 hours respectively) with significant p-value (<0.001).Conclusions: Titrated oral misoprostol is safe and effective for labour induction in primigravida patients with unfavorable cervix
Health-related quality of life of Palestinian preschoolers in the Gaza Strip: a cross-sectional study
Social suffering and the psychological impact of structural violence and economic oppression in an ongoing conflict setting: The Gaza Strip
Structural violence and economic oppression (e.g. control over resources, politically engineered poverty and unemployment) are common features of warfare, yet there is a lack of research exploring the impact this has on civilian wellbeing in conflict‐affected areas. This study, embedded within a human rights and community liberation psychology framework, aims to address this need by studying young Palestinian university graduates living under military blockade and occupation in the Gaza Strip. Semi‐structured interviews were conducted. Thematic analysis indicated that economic and political domains adversely affected multiple aspects of civilian life and wellbeing. The findings revealed the deleterious effects of structural violence and economic oppression which created: human insecurity; poor psychological wellbeing and quality of life; existential, psychological and social suffering; humiliation; injuries to dignity; multiple losses; and led to life being experienced as ‘on hold’. Local expressions and idioms to express distress were identified. The findings contributed to unique insights regarding how continual, systemic, and structural oppression can be potentially more psychologically detrimental than specific incidents of conflict and violence. The implications and the relevance of the findings to mental health and disaster relief are considered. Interventions providing human security and economic security should be prioritised
Experimental Comparative Study on the Performance of Single and Multi-Stage Dry Air Filters
An experimental study on the effect of filter types, relative humidity and using two stage filters on the weight efficiency and pressure drop across the filter was carried out, to complete the study a test rig is designed and built, the rig consist of three sections air duct, of 30 cm ×30 cm cross sectional area, with overall length of 220 cm. Six types of air filters are used in a single stage filters; namely spongy, polyester, synthetic one and two layer aluminum filters. A molten Aluminum powder dust (Type Aluxite No. 25, 98% less than 35 microns and 2% less than 10 microns) is used. In two stage filters study the bag filter is used as a secondary filter while the primary can be any type of the five filters mentioned above. The study shows that the spongy filters gives a maximum efficiency when is used as a single stage filter as compared with the other filters type. Increasing of working environment relative humidity improves the weight efficiency for both single and two stage filters. Two stage filters can improved the filtration process, it is found that the combination of spongy filter and bag filters give a maximum of weight efficiency of about 92% when the relative humidity equals to 90% . Space distance between two stage filters affect the weight efficiency, it is found that the best distance between the spongy filter and bag filter is between 15 to 20 cm
Parent and child agreement for acute stress disorder, post-traumatic stress disorder and other psychopathology in a prospective study of children and adolescents exposed to single-event trauma
Examining parent-child agreement for Acute Stress Disorder (ASD) and Post-Traumatic Stress Disorder (PTSD) in children and adolescents is essential for informing the assessment of trauma-exposed children, yet no studies have examined this relationship using appropriate statistical techniques. Parent-child agreement for these disorders was examined by structured interview in a prospective study of assault and motor vehicle accident (MVA) child survivors, assessed at 2-4 weeks and 6 months post-trauma. Children were significantly more likely to meet criteria for ASD, as well as other ASD and PTSD symptom clusters, based on their own report than on their parent's report. Parent-child agreement for ASD was poor (Cohen's κ = -.04), but fair for PTSD (Cohen's κ = .21). Agreement ranged widely for other emotional disorders (Cohen's κ = -.07-.64), with generalised anxiety disorder found to have superior parent-child agreement (when assessed by phi coefficients) relative to ASD and PTSD. The findings support the need to directly interview children and adolescents, particularly for the early screening of posttraumatic stress, and suggest that other anxiety disorders may have a clearer presentation post-trauma
Time-Fractional Optimal Control of Initial Value Problems on Time Scales
We investigate Optimal Control Problems (OCP) for fractional systems
involving fractional-time derivatives on time scales. The fractional-time
derivatives and integrals are considered, on time scales, in the
Riemann--Liouville sense. By using the Banach fixed point theorem, sufficient
conditions for existence and uniqueness of solution to initial value problems
described by fractional order differential equations on time scales are known.
Here we consider a fractional OCP with a performance index given as a
delta-integral function of both state and control variables, with time evolving
on an arbitrarily given time scale. Interpreting the Euler--Lagrange first
order optimality condition with an adjoint problem, defined by means of right
Riemann--Liouville fractional delta derivatives, we obtain an optimality system
for the considered fractional OCP. For that, we first prove new fractional
integration by parts formulas on time scales.Comment: This is a preprint of a paper accepted for publication as a book

Dynamic 3D shape of the plantar surface of the foot using coded structured light:a technical report
The foot provides a crucial contribution to the balance and stability of the musculoskeletal system, and accurate foot measurements are important in applications such as designing custom insoles/footwear. With better understanding of the dynamic behavior of the foot, dynamic foot reconstruction techniques are surfacing as useful ways to properly measure the shape of the foot. This paper presents a novel design and implementation of a structured-light prototype system providing dense three dimensional (3D) measurements of the foot in motion. The input to the system is a video sequence of a foot during a single step; the output is a 3D reconstruction of the plantar surface of the foot for each frame of the input.
Methods
Engineering and clinical tests were carried out to test the accuracy and repeatability of the system. Accuracy experiments involved imaging a planar surface from different orientations and elevations and measuring the fitting errors of the data to a plane. Repeatability experiments were done using reconstructions from 27 different subjects, where for each one both right and left feet were reconstructed in static and dynamic conditions over two different days.
Results
The static accuracy of the system was found to be 0.3 mm with planar test objects. In tests with real feet, the system proved repeatable, with reconstruction differences between trials one week apart averaging 2.4 mm (static case) and 2.8 mm (dynamic case).
Conclusion
The results obtained in the experiments show positive accuracy and repeatability results when compared to current literature. The design also shows to be superior to the systems available in the literature in several factors. Further studies need to be done to quantify the reliability of the system in clinical environment
Delineating the genotypic and phenotypic spectrum of HECW2-related neurodevelopmental disorders
Background Variants in HECW2 have recently been reported to cause a neurodevelopmental disorder with hypotonia, seizures and impaired language; however, only six variants have been reported and the clinical characteristics have only broadly been defined. Methods Molecular and clinical data were collected from clinical and research cohorts. Massive parallel sequencing was performed and identified individuals with a HECW2-related neurodevelopmental disorder. Results We identified 13 novel missense variants in HECW2 in 22 unpublished cases, of which 18 were confirmed to have a de novo variant. In addition, we reviewed the genotypes and phenotypes of previously reported and new cases with HECW2 variants (n=35 cases). All variants identified are missense, and the majority of likely pathogenic and pathogenic variants are located in or near the C-terminal HECT domain (88.2%). We identified several clustered variants and four recurrent variants (p.(Arg1191Gln);p.(Asn1199Lys);p.(Phe1327Ser);p.(Arg1330Trp)). Two variants, (p.(Arg1191Gln);p.(Arg1330Trp)), accounted for 22.9% and 20% of cases, respectively. Clinical characterisation suggests complete penetrance for hypotonia with or without spasticity (100%), developmental delay/intellectual disability (100%) and developmental language disorder (100%). Other common features are behavioural problems (88.9%), vision problems (83.9%), motor coordination/movement (75%) and gastrointestinal issues (70%). Seizures were present in 61.3% of individuals. Genotype-phenotype analysis shows that HECT domain variants are more frequently associated with cortical visual impairment and gastrointestinal issues. Seizures were only observed in individuals with variants in or near the HECT domain. Conclusion We provide a comprehensive review and expansion of the genotypic and phenotypic spectrum of HECW2 disorders, aiding future molecular and clinical diagnosis and management.Peer reviewe
