There has been a conscious shift towards developing increasingly inclusive applications. However, despite this fact, most research has focused on supporting those with visual or hearing impairments and less attention has been paid to cognitive impairments. The purpose of this study is to analyse touch gestures used for touchscreens and identify which gestures are suitable for individuals living with Down syndrome (DS) or other forms of physical or cognitive impairments. With this information, app developers can satisfy Design for All (DfA) requirements by selecting adequate gestures from existing lists of gesture sets. Twenty touch gestures were defined for this study and a sample group containing eighteen individuals with Down syndrome was used. A tool was developed to measure the performance of touch gestures and participants were asked to perform simple tasks that involved the repeated use of these twenty gestures. Three variables are analysed to establish whether they influence the success rates or completion times of gestures, as they could have a collateral effect on the skill with which gestures are performed. These variables are Gender, Type of Down syndrome, and Socioeconomic Status. Analysis reveals that significant difference is present when a pairwise comparison is performed, meaning individuals with DS cannot perform all gestures with the same ease. The variables Gender and Socioeconomic Status do not influence success rates or completion times, but Type of DS does.

Objectives To compare the demographic and clinical characteristics of children with Down syndrome who did and did not receive polysomnography to evaluate for obstructive sleep apnea after publication of the American Academy of Pediatrics’ guidelines recommending universal screening by age 4 years. Study Design Retrospective cohort study. Setting Single tertiary pediatric hospital. Methods Review was conducted of children with Down syndrome born between 2007 and 2012. Children who obtained polysomnography were compared with children who did not, regarding demographic data, socioeconomic status, and comorbidities. Results We included 460 children with Down syndrome; 273 (59.3%) received at least 1 polysomnogram, with a median age of 3.6 years (range, 0.1-8.9 years). There was no difference in the distribution of sex, insurance status, or socioeconomic status between children who received polysomnography and those who did not. There was a significant difference in race distribution ( P = .0004) and distance from home to the medical center ( P < .0001) between groups. Among multiple medical comorbidities, only children with a history of hypothyroidism ( P = .003) or pulmonary aspiration ( P = .01) were significantly more likely to have obtained polysomnography. Conclusions Overall, 60% of children with Down syndrome obtained a polysomnogram. There was no difference between groups by payer status or socioeconomic status. A significant difference in race distribution was noted. Proximity to the medical center and increased medical need appear to be associated with increased likelihood of obtaining a polysomnogram. This study illustrates the need for improvement initiatives to increase the proportion of patients receiving guideline-based screening.

Compared to parents of children with other types of intellectual disabilities, parents of children with Down syndrome experience less stress and more rewards, although this “Down syndrome advantage” mostly occurs compared to parents of children with autism and before groups are equated. Behaviorally, children with Down syndrome display more sociable interactional styles and baby-faced facial features, along with fewer instances of severe behavior problems. Demographically, parents of children with (versus without) Down syndrome average 5 years older when giving birth; parents are more often well educated, married, of higher socioeconomic status, and they likely provide these children greater financial and cultural resources. In most industrialized societies, rates of Down syndrome seem steady, with easily available, noninvasive prenatal testing counteracted by increasing numbers of women giving birth at older ages. Parenting children with Down syndrome relates to characteristics of children, their parents, and society, all of which intersect in important, underexplored ways.

Abstract Background Esophageal injury caused by cryoballoon-based PVI is common. Cryoablation guided by transoesophageal echocardiography (TEE) for occlusion of the pulmonary vein (PV) is safe and effective. Objective To investigate the protective effect of mechanical displacement of the esophagus by TEE probe in cryoablation of atiral fibrillation. Methods Fifty patients with paroxysmal AF (PAF) were enrolled in the present study. 25 patients underwent cryoablation without TEE (non-TEE group) and the other 25 underwent with TEE (TEE group) for PV occlusion guidance and displacement of the esophagus. In the TEE group during the procedure, TEE was used to guide the movement of the balloon to achieve PV occlusion. And before freezing, the probe of the TEE was moved to displace the esophagus away from the PV being freezed in order to reduce the risk of cryoinjury. All patients underwent esophagogastroscopy within 2 days of the procedure. The patients were followed up in our center at regularly scheduled visits every 2 months. Results There was no significant difference between the TEE group and non-TEE group in regard to the procedure time. The fluoroscopy time in the TEE group was less compared to the non-TEE group (4.1±3.3 min vs. 16.6±6.9 min, P&lt;0.05), and the amount of contrast agent in the TEE group was less than the non-TEE group (4.7±5.7ml vs. 17.9±3.4 ml, P&lt;0.05). The incidence of esophageal injury was significantly lower in TEE group compared with non-TEE group (0 vs. 20%, P&lt;0.05). At a mean of 14.0 months follow-up, success rates were similar between the TEE group and non-TEE group (80.0% vs. 84.0%, P=0.80). Conclusion Cryoablation of AF with TEE for protecting the esophagus from cryoinjury is safe and effective. Lower risk of esophageal injury can be achieved with the help of TEE probe movement for mechanical displacement of the esophagus during freezing.

Near-infrared spectroscopy devices can measure peripheral tissue oxygen saturation (StO<sub>2</sub>). This study aims to compare StO<sub>2</sub> using INVOS® and different O3™ settings (O3<sup>25:75</sup> and O3<sup>30:70</sup>). Twenty adults were recruited. INVOS® and O3™ probes were placed simultaneously on 1 side of forearm. After baseline measurement, the vascular occlusion test was initiated. The baseline value, rate of deoxygenation and reoxygenation, minimum and peak StO<sub>2</sub>, and time from cuff release to peak value were measured. The parameters were compared using ANOVA and Kruskal-Wallis tests. Bonferroni’s correction and Mann-Whitney pairwise comparison were used for post hoc analysis. The agreement between StO<sub>2</sub> of devices was evaluated using Bland-Altman plots. INVOS® baseline value was higher (79.7 ± 6.4%) than that of O3<sup>25:75</sup> and O3<sup>30:70</sup> (62.4 ± 6.0% and 63.7 ± 5.5%, respectively, <i>p</i> &#x3c; 0.001). The deoxygenation rate was higher with INVOS® (10.6 ± 2.1%/min) than with O3<sup>25:75</sup> and O3<sup>30:70</sup> (8.4 ± 2.2%/min, <i>p</i> = 0.006 and 7.5 ± 2.1%/min, <i>p</i> &#x3c; 0.001). The minimum and peak StO<sub>2</sub> were higher with INVOS®. No significant difference in the reoxygenation rate was found between the devices and settings. The time to reach peak after cuff deflation was faster with INVOS® (both <i>p</i> &#x3c; 0.001). Other parameters were similar. There were no differences between the different O3™ settings. There were differences in StO<sub>2</sub> measurements between the devices, and these devices should not be interchanged. Differences were not observed between O3™ device settings.

<b><i>Introduction:</i></b> Neonatal tracheal intubation (TI) outcomes have been assessed by role, but training level may impact TI success and safety. Effect of physician training level (PTL) on the first-attempt success, adverse TI-associated events (TIAEs), and oxygen desaturation was assessed. <b><i>Methods:</i></b> Prospective cohort study in 11 international NEAR4NEOS sites between October 2014 and December 2017. Primary TIs performed by pediatric/neonatal physicians were included. Univariable analysis evaluated association between PTL, patient/practice characteristics, and outcomes. Multivariable analysis with generalized estimating equation assessed for independent association between PTL and outcomes (first-attempt success, TIAEs, and oxygen desaturation ≥20%; attending as reference). <b><i>Results:</i></b> Of 2,608 primary TIs, 1,298 were first attempted by pediatric/neonatal physicians. PTL was associated with patient age, weight, comorbidities, TI indication, difficult airway history, premedication, and device. First-attempt success rate differed across PTL (resident 23%, fellow 53%, and attending 60%; <i>p</i> &#x3c; 0.001). There was no statistically significant difference in TIAEs (resident 22%, fellow 20%, and attending 25%; <i>p</i> = 0.34). Desaturation occurred more frequently with residents (60%), compared to fellows and attendings (46 and 53%; <i>p</i> &#x3c; 0.001). In multivariable analysis, adjusted odds ratio of the first-attempt success was 0.18 (95% CI: 0.11–0.30) for residents and 0.80 (95% CI: 0.51–1.24) for fellows. PTL was not independently associated with adjusted odds of TIAEs or severe oxygen desaturation. <b><i>Conclusion:</i></b> Higher PTL was associated with increased first-attempt success but not TIAE/oxygen desaturation. Identifying strategies to decrease adverse events during neonatal TI remains critical.

Down Syndrome (DS) caused by trisomy 21 results in various congenital and developmental complications in children. It is crucial to cytogenetically diagnose the DS cases early for their proper health management and to reduce the risk of further DS childbirths in mothers. In this study, we performed a cytogenetic analysis of 436 suspected DS cases using karyotyping and fluorescent in situ hybridization. We detected free trisomies (95.3%), robertsonian translocations (2.4%), isochromosomes (0.6%), and mosaics (1.2%). We observed a slightly higher incidence of DS childbirth in younger mothers compared to mothers with advanced age. We compared the somatic aneuploidy in peripheral blood of mothers having DS children (MDS) and control mothers (CM) to identify biomarkers for predicting the risk for DS childbirths. No significant difference was observed. After induced demethylation in peripheral blood cells, we did not observe a significant difference in the frequency of aneuploidy between MDS and CM. In conclusion, free trisomy 21 is the most common type of chromosomal abnormality in DS. A small number of DS cases have translocations and mosaicism of chromosome 21. Additionally, somatic aneuploidy in the peripheral blood from the mother is not an effective marker to predict DS childbirths.

Abstract Study question Does human oocytes in-vitro maturation (IVM) effectiveness change throughout childhood, adolescence and adulthood in girls and women undergoing fertility preservation via ovarian tissue cryopreservation (OTC) prior to chemo-radiotherapy exposure? Summary answer The optimal age for IVM is from menarche to 25 years, while pre-menarche girls and women older than 30 years have extremely low maturation rates. What is known already In vitro maturation of oocytes from antral follicles seen during tissue harvesting is a fertility preservation technique with potential advantages over OTC, as mature frozen and later thawed oocyte used for fertilization poses decreased risk of malignant cells re-seeding, as compared to ovarian tissue implantation. We previously demonstrated that IVM performed following OTC in fertility preservation patients, even in pre-menarche girls, yields a fair amount of oocytes available for IVM and freezing for future use. Study design, size, duration A retrospective cohort study, evaluating IVM outcomes in chemotherapy naïve patients referred for fertility preservation by OTC that had oocyte collected from the medium with attempted IVM between 2003 and 2020 in a university affiliated tertiary center. Participants/materials, setting, methods A total of 133 chemotherapy naïve patients aged 1–35 years with attempted IVM were included in the study. The primary outcome was IVM rate in the different age groups – pre-menarche (1–5 years and ≥6 years), post-menarche (menarche–17 years), young adults (18–24 years) and adults (25–29 and 30–35 years). Comparison between paired groups for significant difference in the IVM rate parameter was done using the Tukey’s Studentized Range (HSD) Test. Main results and the role of chance A gradual increase in mean IVM rate was demonstrated in the age groups over 1 to 25 years (4.6% (1–5 years), 23.8% (6 years to menarche) and 28.4% (menarche to 17 years), with a peak of 38.3% in the 18–24 years group, followed by a decrease in the 25–29 years group (19.3%), down to a very low IVM rate (8.9%) in the 30–35 years group. A significant difference in IVM rates was noted between the age extremes – the very young (1–5 years) and the oldest (30–35 years) groups, as compared with the 18–24-year group (p &lt; 0.001). Number of oocytes matured, percent of patients with matured oocytes and overall maturation rate differed significantly (p &lt; 0.001). Limitations, reasons for caution Data regarding ovarian reserve evaluation was not available for most of the patients, due to our pre-op OTC procedures protocol. None of our patients have used their frozen in-vitro matured oocytes, as such further implications of age on in-vitro matured oocytes quality and implantation potential has yet to be evaluated. Wider implications of the findings: Our finding of extremely low success rates in those very young (under 6 years) and older (≥30 years) patients suggest that IVM of oocyte retrieved during OTC prior to chemotherapy should not be attempted in these age group.

Objective Neuroendovascular procedures rely on successful navigation and stable access to the target vessel. The Stabilizer is a 300 cm long exchange wire with a 0.014 diameter and a soft, flexible stent at the distal end designed to assist with navigation and device delivery. This study aims to assess the efficacy of the Stabilizer for navigation in a variety of challenging environments. Methods The efficacy of the Stabilizer was evaluated using three challenging vascular models: a giant aneurysm model, a severe tortuosity model, and an M1 stenosis model. The Stabilizer was compared with a conventional wire during navigation in each model. Results In the giant aneurysm model, there was no significant difference of success during straightening of a looped wire and significantly higher success rates when advancing an intermediate catheter with the Stabilizer beyond the aneurysm neck compared to a conventional guidewire. The Stabilizer also significantly increased success rates when advancing an intermediate catheter through a model with severe tortuosity compared to a conventional guidewire, as well as exchange maneuver for intracranial stenting in a stenosis model compared to an exchange wire. Conclusions In our experimental model, the Stabilizer significantly improved navigation and device delivery in a variety of challenging settings compared to conventional wires.

Background to study: Effective management of hypertension is influenced by several factors that center on social and economic status of the patient. Identification of these factors will enable informed intervention in the management of hypertensive patients. Objective: The study aimed to determine possible association between blood pressure control and socioeconomic status of patients who are managed in community pharmacies in Rivers State. Method: A descriptive cross-sectional survey of thirty-nine community pharmacies was conducted between July and December 2018.  A total of 195 respondents participated in the study. Every patient’s consent was obtained. Further information on patients’ demographics were extracted from pharmacists’ documentation files. Such include age, medication patient is on, duration of hypertension, co-morbidity, income/ social status, and habits like smoking, alcohol consumption, educational status, and mean blood pressure over the study period. The outcome measure taken as controlled blood pressure was mean BP ≤140/90 mm Hg for the general population and BP 130/80 mmHg for patients with diabetes as co-morbidity. BP >140/90 mm Hg was considered as uncontrolled blood pressure. Result: A total of 195 respondents participated in the study, of which 105(53.8%) were male and 90(46.2%) were female. Out of this number 75(38.5%) were below 40yrs of age, 105(53.8%) were between 41–50yrs of age and only 15(7.7%) were 60yrs and above. More female had BP control compared to the male (OR 1.89, 95% CI (1.16 - 3.0), P=0.009. Patients within ages 41 - 59yrs had more controlled BP compared to older age, 60yrs and above, OR 1.48, 95% CI (0.84 - 2.42) p 0.18. Uncontrolled BP was found more among employed patients and patients with highest monthly income, OR 1.05 95% CI (0.58 - 2.00); OR 1.16 95% CI (0.49 - 2.78) P, 0.36 respectively. Exercise activities have significant impact on BP control as alcohol consumption increased OR of BP control with no significant difference in OR on amount of monthly expenditure on medications. Conclusion: Male gender, employment, and high income earning have negative effect on BP control while exercise is associated with BP control.                    Peer Review History: Received: 4 September 2021; Revised: 10 October; Accepted: 21 October, Available online: 15 November 2021 Academic Editor:  Dr. Gehan Fawzy Abdel Raoof Kandeel, Pharmacognosy Department, National Research Centre, Dokki, 12622,  Giza, Egypt, [email protected]  UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.
