BackgroundMobile health (mHealth) applications are widely valued for their potential to increase self-management among older adults and reduce their healthcare demands. However, the intention to use mHealth of Dutch older adults before the COVID-19 pandemic was modest. Healthcare access was considerably reduced during the pandemic and mHealth services substituted for in person health services. As older adults utilize health services more frequently and have been particularly vulnerable to the pandemic, they can be viewed to have especially benefitted from the transition toward mHealth services. Furthermore, one might expect their intention to use these services and reap the potential benefits has increased, especially during the pandemic.ObjectiveThe aim of this study was to examine whether the intention of Dutch older adults to use medical applications increased during the COVID pandemic and how the explanatory power of the extended Technology Acceptance Model (TAM) developed for this purpose was affected by the onset of the pandemic.MethodsWe conducted a cross-sectional survey using two samples collected before (n = 315) and after (n = 501) the onset of the pandemic. Data was collected using questionnaires which were distributed digitally and on paper, by convenience sampling and snowballing. Participants were 65 years or older, lived independently or in a senior living facility, without cognitive impairment. A controlled analysis was performed to test for significant differences in the intention to use mHealth. The before and after differences in extended TAM variables and their relationship with intention to use (ITU) were analyzed using controlled (multivariate) logistic and linear regression models. These models were also used to explore whether the onset of the pandemic had an effect on ITU not captured by the extended TAM model.ResultsWhile the two samples differed in ITU (p = 0.017; uncontrolled) there was no statistically significant difference in ITU in the controlled logistic regression analysis (p = 0.107). The scores of the extended TAM variables explaining intention to use were all significantly higher, except for Subjective norm and Feelings of Anxiety. The relationships of these variables with intention to use before and after the onset of the pandemic were similar, except for Social relationships which lost its significance. We found no indications of effects of the pandemic on intention to use not captured by our instrument.ConclusionThe intention to use mHealth applications of Dutch older adults has not changed since the onset of the pandemic. The extended TAM model has robustly explained intention to use, with only minor differences after the first months of the pandemic. Interventions targeting facilitation and support are likely to promote the uptake of mHealth. Follow-up studies are needed to investigate whether the pandemic has had long term effects on the ITU of the older adult.

ObjectiveThe objective of the study was to examine the impact of the COVID-19 pandemic on the work of medical personnel in terms of: task scope, preparation to perform medical tasks related to the pandemic, team collaboration, involvement in tasks performed, concerns about performing tasks related to the pandemic, stress levels.MethodsThe mixed-method approach was applied to this cross-sectional study. The online questionnaire which included 40 questions was completed via Google among medical personnel in Poland. Eight semi-structured, in-depth interviews were conducted to deepen the data obtained with the questionnaires.ParticipantsThe questionnaire was completed by 215 healthcare professionals, with the largest group being nurses (56.3%) followed by physicians (22.3%), midwives (11.6%) and other healthcare professionals (e.g., physiotherapists, paramedics, nutritionists – 9.8%). Among the respondents were people who worked in the hospital in the so-called “covid wards” (31.2%) and other hospital wards (60%) as well as people who were employed outside the hospital (8.8%).ResultsThe pandemic affected the nature and range of tasks performed by health professionals. Initially, respondents felt unprepared to work under pandemic conditions, but over time their ratings increased in all areas studied. More than half of respondents reported no change in interpersonal relationship within the team, but nearly 35% noted a worsening and only one in 10 claimed improvement. Study participants rated their own commitment to tasks slightly higher than that of their colleagues (mean 4.9 and 4.4 respectively) but the overall rating was high. The mean self-rating of work stress increased from 3.7 before the pandemic to 5.1 during the pandemic. Most of the respondents were afraid of transmission of the infection to their relatives. Other fears included the possibility of making a medical error, not being able to help the patient, not having enough personal protective equipment (PPE) and contracting SARS-CoV-2.ConclusionThe conducted study revealed that the organization of medical care in the initial period of the pandemic, especially the hospital care of patients infected with SARS-CoV-2, was quite chaotic. The most affected were the people who were transferred to work in the covid wards. Not all medical professionals were prepared to work with the COVID-19 patients, as they lacked experience working in such facilities, especially in intensive care units (ICU). Working under time pressure and under new conditions led mainly to an increase in perceived stress and conflicts between staff.

BackgroundTo explore the central and peripheral retinal and choroidal changes in diabetic patients without clinical diabetic retinopathy (DM-NoDR) using ultra-wide-field swept-source optical coherence tomography angiography (UWF-SS-OCTA).Methods67 DM-NoDR eyes and 32 age-matched healthy eyes were recruited. Retinal and choroidal parameters, including qualitative retinal microangiopathy, vessel flow (VFD) and linear density (VLD), thickness, and volume, were measured in the central and peripheral areas of the 24 × 20 mm2 UWF-SS-OCTA images.ResultsDM-NoDR eyes had significantly more nonperfusion area and capillary tortuosity than controls in the central and peripheral areas (p &lt; 0.05). The presence of central capillary tortuosity was associated with higher levels of serum creatinine (OR 1.049, 95%CI 1.001–1.098; p = 0.044) and blood urea nitrogen (OR 1.775, 95%CI 1.051–2.998; p = 0.032) in DM-NoDR eyes. For DM-NoDR eyes versus controls, VFD in the 300-μm annulus around the foveal avascular zone, superficial capillary plexus (SCP), and full retina, and SCP-VLD significantly decreased, while VFD in the deep capillary plexus (DCP), retinal thickness, and retinal volume increased (p &lt; 0.05). Analysis in the central and peripheral areas recapitulated all these findings, except for decreased peripheral thickness and volume and no difference in peripheral DCP-VFD. In DM-NoDR eyes, choriocapillaris-VFD, choroidal thickness, and choroidal volume increased in the central area, while VFD in the large and medium choroidal vessel layer decreased in the whole image (p &lt; 0.05).ConclusionRetinal and choroidal changes already existed in the central and/or peripheral areas of DM-NoDR eyes. UWF-SS-OCTA, enabling the visualization of the peripheral fundus area, is a promising image technique for the early detection of fundus changes in DM-NoDR patients.

Published: June 2023

IntroductionThe extent to which additional health benefits of accumulating twice the minimum amount of time in moderate-to-vigorous physical activity (MVPA) affects indicators of physical function in older adults is unclear. Therefore, the aim of the present study was to assess indicators of physical function in older adults who accumulate at least 150 but less than 300 min/week of MVPA compared to those accumulating at least 300 min/week.MethodsIndicators of physical function, including handgrip strength, 5 times sit-to-stand test (5-STS), squat jump and 6-min walk test (6MWT) were assessed in a sample of 193 older men (n = 71, 67 ± 2 years), and women (n = 122, 67 ± 2 years), who all accumulated at least 150 weekly minutes of MVPA. Time in MVPA was assessed by accelerometry during 1 week and engagement in muscle strengthening activities (MSA) was assessed by self-report. Protein intake was assessed by a food-frequency-questionnaire. Participants were classified as physically active (≥150 but &lt;300 min of MVPA per week) or as highly physically active (≥300 min of MVPA per week).ResultsFactorial analysis of variance revealed that older adults accumulating at least 300 min of MVPA per week had a significantly (p &lt; 0.05) better 6MWT performance and overall physical function compared to the less active group. These findings remained significant after further adjustment for MSA, sex, waist circumference and protein intake. In contrast, no significant differences in indicators of muscle strength were observed between the two groups.DiscussionAdherence to twice the recommended minimum amount of weekly MVPA time is related to a better physical function, evidenced by a better walking performance compared to adherence to the minimum weekly amount of MVPA. This finding emphasizes the benefits of accumulating daily MVPA beyond the minimum recommended amount to optimize the ability to perform activities of daily living, thus reducing the burden of physical disability and related health-care costs.

BackgroundIn Norway, the introduction of an interdisciplinary subject named Public Health and Life skills has brought about renewed attention to how health is conceptualized and taught within and across school subjects. Physical education (PE) is one subject that has traditionally been linked to health outcomes. However, a narrow focus on increased physical activity as the main outcome of PE could be counterproductive in the pursuit of health. Critical health literacy (CHL) is put forward as a resource for health that can be nurtured in the PE context; this study hypothesizes that academic achievement in PE is positively associated with some aspects of CHL.MethodsThis cross-sectional study included 521 pupils aged 13–15 years old from five lower secondary schools in Norway. Structural equation models were used as the primary statistical analysis to test the hypothesis. The study controlled for parents’ education, leisure physical activity, and participation in sports club activities.ResultsThe results confirm the hypothesis, showing a positive and significant association between PE and CHL. The association remains when controlling for parents’ education, leisure physical activity, and participation in sports club activities (β^PE→CHL−C1 = 0.264, p = 0.001; β^PE→CHL−C2 = 0.351, p &lt; 0.000).ConclusionIn our sample, academic achievement in PE was associated with higher levels of CHL. This study contributes to the ongoing discussion on the health benefits of PE. We argue that a resource-based health perspective can produce the appropriate aims for health in PE contexts and that the CHL concept contributes to illuminating key areas, promoting suitable teaching strategies, and bringing balance between an individual and collective focus for future health education, both within PE and across different subjects in school contexts.

IntroductionPedicle screw fixation (PSF) has been the standard therapy for the treatment of various spinal diseases. Although complications are identified regularly, iatrogenic vascular injury is one of the rare but life-threatening complications. In this literature, we describe the first case of inferior vena cava (IVC) injury during pedicle screw removal.Case descriptionA 31-year-old man was treated by percutaneous pedicle screw fixation for an L1 compression fracture. After a year, the fracture healed well and hardware removal surgery was performed. During the procedure, the hardware on the right was removed unremarkably except for the L2 pedicle screw which slipped into the retroperitoneum because of the improper technique. The CT angiogram revealed the screw had breached the anterior cortex of the L2 vertebral body and penetrated the IVC. After multidisciplinary cooperation, the defect of IVC was reconstructed and the L2 screw was removed from the posterior approach in the end.ResultThe patient recovered well and was discharged after 3 weeks without further events. The removal of the contralateral implants was unremarkable at 7 months postoperatively. At the 3-year follow-up, the patient returned to his normal daily activity without any complaints.ConclusionAlthough pedicle screw removal is a rather simple procedure, severe complications may have occurred from this procedure. Surgeons should keep vigilant to avoid the complication noted in this case.
THE NEED FOR REVITALIZING ZAKAH REGULATION TOWARD PRODUCTIVE ZAKAH
Authors: Nafi' Hasbi M. Zidny 
Published: June 2023

Zakah management needs to be revitalized as the results achieved are far from the goals set. The efficient collection of zakah will contribute to people's welfare. This study analyzes Yusuf Qaradawi's productive zakah perspective in Fiqh al-Zakah to examine the regulation of management zakah in Indonesia. Adopting Qaradawi's thought, the government should develop the zakahs' rules, management, and implementation. The government also needs to re-regulate zakah from Muslim communities, such as zakah of professions, agriculture, plantations, gold, silver, and the like. Likewise, if the zakah provisions have been reached (nisab and haul), the government must take zakah out from savings or deposits owned by Muslim communities in banks.
Features of wastewater composition at small-scale treatment facilities

Состав сточных вод малых объектов значительно отличается от состава городских сточных вод как по концентрациям загрязнений, так и по их пропорции. Представлена информация о проведении сбора и анализа данных многолетних наблюдений за составом и температурой сточных вод малых поселений по 31 очистным сооружениям. Выявлено, что для данных объектов характерно повышенное содержание азота при средних концентрациях органических веществ. Такая диспропорция приводит к дефициту субстрата для осуществления биологической очистки – денитрификации, что требует дозирования внешнего источника органики. В поступающей на очистные сооружения воде очень низкое соотношение N–NH4/Nобщ, что свидетельствует о незавершенной аммонификации и необходимости учета общего азота при проведении лабораторного контроля. Для некоторых объектов температура поступающих сточных вод в течение большей части года ниже 10–12 °С, что значительно снижает эффективность биохимических процессов очистки.
The composition of wastewater at small-scale treatment facilities differs significantly from the composition of municipal wastewater both in terms of pollution concentrations and their proportions. Information is presented on the collection and analysis of data from long-term observations of the composition and temperature of wastewater from small settlements at 31 treatment facilities. It has been revealed that an increased concentration of nitrogen at medium concentrations of organic substances is typical for these facilities. Such a disproportion results in a shortage of substrate for biological treatment – denitrification; consequently, dosing an external source of organic matter is required. Wastewater supplied to the treatment facilities has a very low N–NH4/Ntotal ratio, which indicates incomplete ammonification and the need to take into account total nitrogen during laboratory control. At some facilities, the temperature of incoming wastewater is below 10–12 °C during most of the year, which significantly reduces the efficiency of biochemical treatment processes.

Повышение надежности систем водоотведения обеспечивается мероприятиями, предотвращающими попадание неочищенных сточных вод в грунт и на поверхность земли. К таким мероприятиям относятся резервирование напорных и безнапорных трубопроводных участков сети, использование их аккумулирующей способности и устройство аварийно-регулирующих резервуаров. На основании оценки стоимости жизненного цикла проведены исследования эффективности применения аварийно-регулирующих резервуаров при канализационных насосных станциях. Показано, что при определенной длине напорных трубопроводов в две нитки и более экономически выгодным может быть вариант с устройством аварийно-регулирующих резервуаров. В итоге получены зависимости эффективности устройства аварийно-регулирующих резервуаров от длины напорных трубопроводов и производительности насосных станций. Для систем водоотведения г. Иркутска все канализационные насосные станции разделены на две группы с устройством аварийно-регулирующих резервуаров и двух напорных трубопроводов. Результаты исследований будут полезны при актуализации схемы развития систем водоснабжения и водоотведения города.
Improving the reliability of wastewater disposal systems is provided by measures that prevent the intrusion of raw wastewater into the ground and spills onto the land surface. Such measures include backing up pressure and gravity pipeline sections of the network, using their accumulating capacity and installing emergency storage tanks. Based on the life cycle cost assessment, studies of the effectiveness of using emergency storage tanks at wastewater pumping stations were carried out. It is shown that with a certain length of pressure pipelines of two or more strings, the option of installing emergency storage tanks may be most economically viable. As a result, dependences of the efficiency of installing emergency storage tanks on the pressure pipeline length and pumping station capacity were obtained. For wastewater disposal systems in Irkutsk, all wastewater pumping stations are divided into two groups with emergency storage tanks and two pressure pipelines. The results of the study will be useful in updating the scheme for the development of the water supply and wastewater disposal systems of the city.
