Abstract Research projects, initiatives and conferences that include patients as partners rather than as participants are becoming more common. Including patients as partners (what we will call ‘patient partners’) is an approach called patient engagement or involvement in research, and we will call it patient engagement throughout this paper. Patient engagement moves traditional health research conferences and events to include a broader audience for their knowledge exchange and community building efforts, beyond academics and healthcare professionals. However, there are few examples of conferences where patients are given the opportunity to fully lead. Our conference went beyond patient engagement – it was patient-led. Patient partners conceived, planned, and decided on all aspects of a virtual conference. We present the work and processes we undertook throughout 2023 to create and produce a free conference called “PxP: For patients, by patients” or PxP for short, with a tagline of “Partnering to make research stronger.” PxP was patient-led and about patient engagement in research rather than a specific disease or condition. PxP was supported by the Canadian Institutes of Health Research Institute of Musculoskeletal Health and Arthritis. The PxP website, known as the PxP Hub, now houses the conference recordings along with resources about patient engagement in research. These resources were recommended by the PxP Steering Committee members, speakers, and others who attended the 2023 conference. Here we lead you through how the idea for PxP was generated; how the international patient partner Steering Committee was convened and supported; how PxP was brought to life over nine months; the PxP 3-day event and feedback collected to improve future efforts; trade-offs, challenges and learnings; and resources required to support this type of event. We close with what the future holds for PxP in 2024 and beyond. It’s time to elevate patients into leadership roles for conferences and events, and we encourage you to adopt the PxP ethos by using or adapting our approach and resources to support your opportunity.

The COVID-19 outbreak has impacted many daily activities and services we depend on. Due to changes in waste quantity and types, solid waste management (SWM) services such as waste collection, transportation, and treatment/disposal suffered. Global rules and mandates were issued to address these changes and the COVID-19 pandemic. This mini review examines seven countries and summarises the pandemic’s effects on municipal solid waste (MSW) and medical waste (MW) generation in terms of amount and composition, the SWM sector’s challenges, and government or other SWM guidelines and management measures. The data are analysed to provide suggestions for stakeholders on SWM worker protection, waste segregation, and recycling. This article identified that extending MW incineration, separating infectious waste at the source, and discontinuing recycling for infection control are the best ways to manage solid waste. The waste management system’s readiness was crucial to the pandemic response. Thus, countries like China, which has a robust SWM system, were able to contain the crisis and restrict danger, while others with weaker systems struggled. Additionally, the study highlights the importance of revising waste management policies and developing crisis response strategies that integrate flexible, innovative solutions to adapt quickly to changing waste demands and ensure public health and environmental protection during global health crises.

Acanthamoeba spp. are free-living amebae (FLA) found worldwide in soil and many types of water, including lakes, rivers, and tap water (1-3). Acanthamoeba amebae can cause keratitis, which is an [...]

Abstract Background It is unknown whether the existence of severe bystander damage will affect left ventricular (LV) healing following primary percutaneous coronary intervention (PPCI). The aim of the present analysis was to follow LV recovery using 2D speckle tracking echocardiography (2-D STE) in cases with single versus multiple vessel disease with acute myocardial infarction (AMI) who underwent PPCI and to assess major adverse cardiovascular events (MACEs) within 3 months. Patients and methods This work was conducted at Assiut University Heart Hospital. Of 1026 screened subjects with AMI needing PPCI and assessed for eligibility, only 89 cases fulfilled the inclusion criteria. They were classified into Group A: single vessel and Group B: multiple vessel (≥ 2 vessels) disease. Their data were obtained on admittance and after 90 days. Results In group A compared to group B, there was a statistically preferable value at baseline in the global longitudinal strain- Apical 2 chamber (GLS-A2C) (-12.05 ± 3.57 vs. -10.38 ± 3.92, P = 0.039). At follow-up, the improvement was in all 2-D STE variables, including GLS-long axis (GLS-LAX) (-13.09 ± 3.84 vs.-10.75 ± 3.96, P = 0.006), GLS- apical 4 chamber (GLS-A4C) (-13.23 ± 3.51 vs.-10.62 ± 4.08, P = 0.002), GLS-A2C (-13.85 ± 3.41 vs-10.93 ± 3.97, P

We describe 10 patients with nonkeratitis Acanthamoeba infection who reported performing nasal rinsing before becoming ill. All were immunocompromised, 7 had chronic sinusitis, and many used tap water for nasal rinsing. Immunocompromised persons should be educated about safe nasal rinsing to prevent free-living ameba infections.

Hybrid and online synchronous delivery of courses is a time-demanding approach to teaching and learning systems that is designed to engage students in investigations of authentic concepts or problems without coming to the pre-assigned classrooms two or three times a week. This study presents perceptions and attitudes of students that attended a hybrid course in environmental engineering that suddenly converted to an online synchronous delivery due to COVID-19. It also presents an assessment of the hybrid and online synchronous delivery approach on the final exam scores as well as the final grades of the same course. The course, 'Introduction to Environmental Engineering', was developed as an online course for Civil and Environmental Engineering program students and delivered with hybrid and online synchronous options due to COVID-19 pandemic for several semesters to test the concept. In the hybrid delivery set up, all the quizzes and homework assignments were online while the midterm and final exams were in-class. For Spring 2020 the final exam was online and for Summer 2020 both the midterm and final exams were online due to COVID-19 adjustment. At the very end of the semesters, an online anonymous survey was conducted with five questions to understand the students' perception and attitude on exam taking options and learning environment. Students' perceptions and attitudes about online synchronous delivery approach compared to hybrid delivery approach, as well as the learning outcomes, appeared at face value not to be favorable. However, statistical analysis revealed that differences between online synchronous delivery and the Pre-COVID-19 hybrid delivery were not significant, indicating that, at least for these engineering students, online synchronous delivery is a justifiable option.

The study aimed to examine school drug education and agile leadership and lawlessness factors in children involving adults. This report led to a study on child narcotics crimes. 17 district court decisions from 2017-2020 are the unit of analysis, using the Question Nvivo-12 plus software process. The aim of using Nvivo-12 plus is to analyze data with a data coding model. In addition, the writers also interviewed main witnesses, including judges who prosecuted child narcotics cases. . The data analysis procedure includes a validity test using triangulation of sources, time, and place. Grouping of data in the form of images and tables that have been processed for analysis with three data analysis techniques through percentages, making explanations, and comparing with theories or previous research results. According to the findings of the study, drugs education for youngsters involved in narcotics cases is critical. Furthermore, economic constraints, unsatisfactory home conditions, invites from acquaintances, and the influence of social media are all variables that lead to children committing narcotics offenses. In addition to these factors, the authors also found something new that makes children entangled in narcotics crimes, namely the involvement of adults who use children in the narcotics trade. For these factors, agile leadership is need, especially adult leaders with sensitivity, leadership unity, and quality of optimizing resources to protect children from the effects of drug abuse and the need to build particular educational institutions for children involved in crime. So children are given adequate education and skills, so they are not entangled again in drug cases.

Abstract Chromium is a hazardous compound from industrial processes, known for its toxicity, mutagenicity, teratogenicity, and carcinogenicity. Chemical methods are efficient but cost-effective alternatives with reduced sludge are sought. Electro-coagulation, utilizing low-cost iron plate electrodes, was explored for factual tannery wastewater treatment in this manuscript. Operating parameters such as initial chromium concentration, voltage, electrode number, operating time, agitation speed and current density has been studied to evaluate the treatment effeciency. Under optimal conditions (15 V, 0.4 mA/cm2, 200 rpm, 330 ppm chromium, 8 iron electrodes with a total surface area of 0.1188 m2, 3 h), chromium elimination was 98.76%. Iron anode consumption, power use, and operating cost were 0.99 gm/L, 0.0143 kW-h/L, and 160 EGP/kg of chromium eliminated, respectively. Kinetics studies were pursued first-order reaction (97.99% correlation), and Langmuir isotherms exhibited strong conformity (Langmuir R2: 99.99%). A predictive correlation for chromium elimination (R2: 97.97%) was developed via statistical regression. At HARBY TANNERY factory in Egypt, industrial sewage treatment achieved a final chromium disposal rate of 98.8% under optimized conditions.

Abstract Background Eating frequency may affect body weight and cardiometabolic health. Intervention trials and observational studies have both indicated that high- and low-frequency eating can be associated with better health outcomes. There are currently no guidelines to inform how to advise healthy adults about how frequently to consume food or beverages. Aim To establish whether restricted- (≤ three meals per day) frequency had a superior effect on markers of cardiometabolic health (primary outcome: weight change) compared to unrestricted-eating (≥ four meals per day) frequency in adults. Methods We searched Medline (Ovid), Embase, CINAHL (EBSCO), Cochrane Central Register of Controlled Trials (CENTRAL), CAB Direct and Web of Science Core Collection electronic databases from inception to 7 June 2022 for clinical trials (randomised parallel or cross-over trials) reporting on the effect of high or low-frequency eating on cardiometabolic health (primary outcome: weight change). Trial interventions had to last for at least two weeks, and had to have been conducted in human adults. Bias was assessed using the Cochrane Risk of Bias tool 2.0. Standardized mean differences (SMD) and 95% confidence intervals were calculated for all outcomes. Certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Results Seventeen reports covering 16 trials were included in the systematic review. Data from five trials were excluded from meta-analysis due to insufficient reporting. 15 of 16 trials were at high risk of bias. There was very low certainty evidence of no difference between high- and low-frequency eating for weight-change (MD: -0.62 kg, CI95: -2.76 to 1.52 kg, p = 0.57). Conclusions There was no discernible advantage to eating in a high- or low-frequency dietary pattern for cardiometabolic health. We cannot advocate for either restricted- or unrestricted eating frequency to change markers of cardiometabolic health in healthy young to middle-aged adults. Protocol registration CRD42019137938.

Abstract Background Proper proximal contact in direct composite restorations is crucial for periodontal health. Over a one-year period, this study was conducted to assess successive biological changes in proximal contact tightness PCT in class II direct composite restorations and the adjacent teeth by applying sectional matrix system along with different contact forming instruments. Methods 72 direct compound class II composite restorations were performed in patients aged 18–40 years and divided into 4 groups: Group I (n = 18): proximal contact was restored with Palodent plus sectional matrix system, Group II (n = 18): Trimax as contact forming instrument, Group III (n = 18): Perform as contact forming instrument and Group IV (n = 18): Contact pro as contact forming instrument. All contact forming instruments were used along with Palodent plus matrix system. PCT was measured using a digital force gauge before (T0), immediate post operative (T1) and at 3 (T2), 6 (T3), 9 (T4), and 12 months (T5) after restorative treatment. Using One-Way ANOVA, Tukey’s post hoc test, and Bonferroni correction, PCT values were compared between groups before and after the intervention restoration. Meanwhile, for comparisons within groups, a paired t-test was conducted (p ≤ 0.05). Results Contact forming instruments combined with Palodent plus sectional matrix system achieved better PCT. Trimax led to a statistically considerable tighter proximal contacts than the other groups (p

Abstract Background Endogenous estrogen is cardio-protective in healthy premenopausal women. Despite this favorable action of estrogen, animal models depict a detrimental effect of estradiol on vascular function in the presence of diabetes. The present study sought to determine the role of endogenous estradiol on endothelial function in women with type 1 diabetes. Method 32 women with type 1 diabetes (HbA1c = 8.6 ± 1.7%) and 25 apparently healthy women (HbA1c = 5.2 ± 0.3%) participated. Flow-mediated dilation (FMD), a bioassay of nitric-oxide bioavailability and endothelial function was performed during menses (M) and the late follicular (LF) phase of the menstrual cycle to represent low and high concentrations of estrogen, respectively. In addition, a venous blood sample was collected at each visit to determine circulating concentrations of estradiol, thiobarbituric acid reactive substances (TBARS), and nitrate/nitrite (NOx), biomarkers of oxidative stress and nitric oxide, respectively. Data were collected in (1) 9 additional women with type 1 diabetes using oral hormonal birth control (HBC) (HbA1c = 8.3 ± 2.1%) during the placebo pill week and second active pill week, and (2) a subgroup of 9 demographically matched women with type 1 diabetes not using HBC (HbA1c = 8.9 ± 2.1%). Results Overall, estradiol was significantly increased during the LF phase compared to M in both type 1 diabetes (Δestradiol = 75 ± 86 pg/mL) and controls (Δestradiol = 71 ± 76 pg/mL); however, an increase in TBARS was only observed in patients with type 1 diabetes (ΔTBARS = 3 ± 13 µM) compared to controls (ΔTBARS = 0 ± 4 µM). FMD was similar (p = 0.406) between groups at M. In addition, FMD increased significantly from M to the LF phase in controls (p = 0.024), whereas a decrease was observed in type 1 diabetes. FMD was greater (p = 0.015) in patients using HBC compared to those not on HBC, independent of menstrual cycle phase. Conclusion Endogenous estradiol increases oxidative stress and contributes to endothelial dysfunction in women with diabetes. Additionally, HBC use appears to be beneficial to endothelial function in type 1 diabetes.
