Structural equation model of the relationship between functional ability, mental health, and quality of life in older adults living alone
Authors: Yi YuMi , Park Yeon-Hwan 
Published: August 2022

Aims
Living alone, a reality in an increasing number of older adults recently, is a risk factor for low quality of life. This study identified the predictors of quality of life in older adults living alone based on mental health and the International Classification of Functioning, Disability, and Health.

Methods
This secondary data analysis used information from the 2018 Assessing the Requirements of Customized Health Care and Daily Living Support Services survey (N = 1,022), collected from adults aged ≥ 65 living alone in Siheung City, South Korea, from August to October 2018. The exogenous variables were body functions (hand grip strength, timed “up and go” test score, and body mass index), daily living activities (Korean Instrumental Activities of the Daily Living Scale), social activity participation (social activity engagement, neighbor contacts, and family contacts), and participation in economic activity (frequency). The endogenous variables were mental health (Geriatric Depression Scale Short Form—Korean Version and UCLA Loneliness Scale) and quality of life (EuroQoL-5 Dimension-3 Level and EuroQoL-Visual Analog Scale).

Results
After modifying the hypothetical model, which had failed to satisfy the recommended fitness level, the (modified) model had good fitness indices Q (CMIN / df) 2.90, GFI 1, AGFI 1, RMSEA 0.04, CFI 0.90 and PCFI 0.53. Of the nine pathways of the modified model, five were statistically significant. Quality of life was affected by body functions, daily living activities, social activity participation, and mental health. These variables explained 68.2% of the factors affecting quality of life.

Conclusions
By highlighting the role of mental health, this model provides a useful framework for improving the quality of life of older adults who live alone and function at various levels in the community. Focusing on advancing mental health through body functions, daily living activities, and social activity participation can improve quality of life.

Published: August 2022

Context
Prolactin, a hormone synthesized by the anterior pituitary gland demonstrates promise as a neuroprotective agent, however, its role in humans and in vivo during injury is not fully understood.

Objective
To investigate whether elevated levels of prolactin attenuate injury to the retinal nerve fiber layer (RNFL) following compression of the optic chiasm in patients with a prolactin secreting pituitary macroadenoma (i.e., prolactinoma).

Design setting and participants
A retrospective cross-sectional study of all pituitary macroadenoma patients treated at a single institution between 2009 and 2019.

Main outcome measure(s)
Primary outcome measures included RNFL thickness, mean deviation, and prolactin levels for both prolactin-secreting and non-secreting pituitary macroadenoma patients.

Results
Sixty-six patients met inclusion criteria for this study (14 prolactin-secreting and 52 non-secreting macroadenoma patients). Of 52 non-secreting macroadenoma patients, 12 had moderate elevation of prolactin secondary to stalk effect. Patients with moderate elevation in prolactin demonstrated increased RNFL thickness compared to patients with normal prolactin levels (p < 0.01). Additionally, a significant positive relation between increasing levels of prolactin and RNFL thickness was identified in patients with moderate prolactin elevation (R = 0.51, p-value = 0.035). No significant difference was identified between prolactinoma patients and those with normal prolactin levels.

Conclusions
Moderately increased serum prolactin is associated with increased RNFL thickness when compared to controls. These associations are lost when serum prolactin is < 30 ng/ml or elevated in prolactinomas. This suggests a neuroprotective effect of prolactin at moderately increased levels in preserving retinal function during optic chiasm compression.

Authors: Feijen-de Jong Esther I. , Warmelink J. Catja , van der Stouwe Relinde A. , Dalmaijer Maria , Jansen Danielle E. M. C. 
Published: August 2022

Background
Proper implementation of interventions by health professionals has a critical effect on their effectiveness and the quality of care provided, especially in the case of vulnerable pregnant women. It is important, therefore, to assess the implementation of interventions in care settings to serve as input to improve implementation.

Objective
The aim of this study is to identify factors that influence the implementation of interventions for vulnerable pregnant women in the North of the Netherlands from the perspective of health professionals. In this region, an intergenerational transfer of poverty is apparent, leading to many health problems and the transfer of unhealthy lifestyles and the associated diseases to subsequent generations.

Methods
We used a qualitative research design. Semi-structured interviews with 39 health professionals were conducted between February 2019 and April 2020. To analyse the findings, the MIDI (Measurement Instrument for Determinants of Innovations) was used, an instrument designed to identify what determinants influence the actual use of a new or existing innovation.

Results
We found two themes that influence the implementation of interventions: 1. The attitude of health professionals towards vulnerable pregnant women: stereotyped remarks and words expressing the homogenization of vulnerable pregnant women. 2. A theme related to the MIDI determinants, under which we added six determinants.

Conclusion
Our research showed that many factors influence the implementation of interventions for vulnerable pregnant women, making the optimal implementation of interventions very complex. We highlight the need to challenge stereotypical views and attitudes towards specific groups in order to provide relation-centred care, which is extremely important to provide culturally appropriate care. Health professionals need to reflect on their own significant influence on access to and the use of care by vulnerable groups. They hold the key to creating partnerships with women to obtain the best health for mothers and their babies.
Association between sarcopenia and osteoarthritis: A protocol for meta-analysis
Authors: Wang Haochen , Wang Ning , Wang Yilun , Li Hui 
Published: August 2022

Background
Sarcopenia, a relatively new syndrome referring to the age-related decline of muscle strength and degenerative loss of skeletal muscle mass and function, often resulting in frailty, disability, and mortality. Osteoarthritis, as a prevalent joint degenerative disease, is affecting over 250 million patients worldwide, and it is the fifth leading cause of disability. Despite the high prevalence of osteoarthritis, there are still lack of efficient treatment potions in clinics, partially due to the heterogeneous and complexity of osteoarthritis pathology. Previous studies revealed the association between sarcopenia and osteoarthritis, but the conclusions remain controversial and the prevalence of sarcopenia within osteoarthritis patients still needs to be elucidated. To identify the current evidence on the prevalence of sarcopenia and its association with osteoarthritis across studies, we performed this systematic review and meta-analysis that would help us to further confirm the association between these two diseases.

Methods and analysis
Electronic sources including PubMed, Embase, and Web of Science will be searched systematically following appropriate strategies to identify relevant studies from inception up to 28 February 2022 with no language restriction. Two investigators will evaluate the preselected studies independently for inclusion, data extraction and quality assessment using a standardized protocol. Meta-analysis will be performed to pool the estimated effect using studies assessing an association between sarcopenia and osteoarthritis. Subgroup analyses will also be performed when data are sufficient. Heterogeneity and publication bias of included studies will be investigated.

Alcohol use among Congolese Babembe male refugees in Tarrant County: A qualitative study
Authors: Diese Elvis Longanga , Raines-Milenkov Amy , Felini Martha , Akpan Idara , Hussain Arbaz , Baker Eva 
Published: August 2022

Background
Refugees are at high risk of alcohol abuse due to experiences in their country of origin, transit camps, and in host countries. Congolese have been the largest group of refugees resettled in the US since 2016 and Babembe represent one of the largest Congolese refugee sub-groups. There is a growing body of literature highlighting substance abuse among refugees resettled in the US, but little is known about Congolese Babembe. This study aimed to explore factors and practices contributing to alcohol abuse among Congolese Babembe refugees.

Methods
A qualitative research design employing a narrative inquiry approach was used in this study. One focus group discussion was conducted with a semi-structured guide in February 2020.A total of 19 hard-to-reach male refugee participants were recruited through snowball sampling. Audio recordings were translated and transcribed before a thematic content analysis was conducted using Nvivo 10.

Results
The main themes arose in the focus group analysis. First, the role of war, trauma, and migration in the onset of alcohol abuse in a community that once limited alcohol use to only older men for socialization. Second, refugees viewed alcohol abuse in their community as a result of post- resettlement cultural loss. Third, refugees perceived alcohol as serving a purpose to help cope with stressful conditions in the US and bad news received from loved ones in Africa. Further analysis shows the role of interactions with armed forces and other cultures during war and migration contributed to the adoption of alcohol abuse behavior.

Conclusion
Findings from this study suggest that factors contributing to alcohol abuse among Congolese Babembe refugees include personal traumatic experiences, loss of cultural identity, and conducive conditions in the host country. Understanding these factors can guide the development of appropriate interventions to prevent alcohol abuse in this vulnerable community. Further research is needed to include Babembe women’s perspectives.

Published: August 2022

Purpose
To assess the accuracy of refraction measurements by ClickCheckTM compared with the standard practice of subjective refraction at a tertiary level eye hospital.

Design
Diagnostic accuracy trial.

Methods
All participants, recruited consecutively, underwent auto-refraction (AR) and subjective refraction (SR) followed by refraction measurement using ClickCheckTM (CR) by a trained research assistant. Eyeglass prescriptions generated using ClickCheckTM and the resulting visual acuity (VA) was compared to SR for accuracy. Inter-rater reliability and agreement were determined using Intra-class correlation and Bland Altman analysis respectively.

Results
The 1,079 participants enrolled had a mean (SD) age of 39.02 (17.94) years and 56% were women. Overall, 45.3% of the participants had refractive error greater than ±0.5D. The mean (SD) spherical corrections were -0.66D (1.85) and -0.89D (2.20) in SR and CR respectively. There was high level of agreement between the spherical power measured using SR and CR (ICC: 0.940 (95% CI: 0.933 to 0.947). For the assessment of cylindrical correction, there was moderate level of agreement between SR and CR (ICC: 0.493 (0.100 to 0.715). There was moderate level of agreement between the VA measurements performed by using corrections from SR and CR (ICC: 0.577 (95% CI: 0.521–0.628). The subgroup analysis based on the age categories also showed high level of agreement for spherical corrections between the two approaches (ICC: 0.900). Bland Altman analysis showed good agreement for spherical corrections between SR and CR (Mean difference: 0.224D; 95% LoA: -1.647 D to 2.096 D) without evidence of measurement bias.

Conclusions
There was a high level of agreement for spherical power measurement between CR and SR. However, improvements are needed in order to accurately assess the cylindrical power. Being a portable, low-cost and easy-to-use refraction device, ClickCheckTM can be used for first level assessment of refractive errors, thereby enhancing the efficiency of refractive services, especially in low- and-middle-income countries.

Published: August 2022

BackgroundMalignancies that spread to the lymph nodes may be identified through surgical biopsy, and treatment of metastatic disease may be through lymph node dissection. These surgeries, however, may be associated with significant adverse outcomes, particularly wound complications, the true incidence of which remains unknown. Multiple studies have reported their individual rates of complications in isolation. The aim of this study will be to systematically evaluate data that presents the incidence of wound complications in patients undergoing these surgeries.MethodsWe have designed and registered a protocol for a systematic review and meta-analysis of studies presenting incidence data. We will search MEDLINE, EMBASE and CENTRAL for relevant articles. Meta-analysis will be undertaken to synthesise an overall incidence of surgical site infection, wound dehiscence, haematoma and seroma. Subgroup analyses will investigate the effects of anatomical location, primary malignancy and study design on pooled incidence. Risk of bias will be evaluated for each included study using bespoke tools matched to the study design.DiscussionThe results of this study will provide the incidence of wound complications and secondary complications following lymph node surgery. This will directly impact upon the consent process, and may influence the nature of future research studies aimed at reducing post-operative complications.

ANALYSIS RISK MAPPING OF BATIK KARAWANG DISTRIBUTION TO EXPAND DISTRIBUTION COVERAGE
Authors: Sayuti Muhamad 
Published: August 2022

Tourism is a resource that can be developed in Indonesia because it has a positive impact on economic growth both locally and nationally which can increase regional income so that local community empowerment and poverty alleviation can be done. One of the efforts in developing the local economy is by making regional superior products such as the development of batik that has been internationally recognized by UNESCO as Indonesia's cultural heritage. Karawang has distinctive batik and is different from batik from other regions, so this batik is admired by the Karawang community itself. The distribution of Karawang batik still has many obstacles both in terms of regional conditions, the number of craftsmen and branding that are not yet strong. This research focuses on re-mapping the flow of Karawang batik distribution with reference to risk management. This research is very important to improve the flow distribution of Karawang batik, so that it will make the distribution coverage of this batik even wider. This study uses a mapping method distribution flow, taking into account the risk management. The risk management itself uses a Risk Register map, so that the risk exposure from Karawang batik will be increasingly clear and is expected to make mitigation and minimize risk. After conducting a causal analysis and risk map, several proposals were extended to expand the scope of marketing, including the Religious Community, the Government Organizations, Banking Companies, Private Companies, Motor and Car Commodities. The proposal is expected to be implemented and have a positive influence. Furthermore, it will be monitored once a year to see the changes < Keyword: batik karawang; causal analysis; risk register map
How Welfare Policies Can Change Trust – A Social Experiment Assessing the Impact of Social Assistance Policy on Political and Social Trust
Authors: Betkó János , Spierings Niels , Gesthuizen Maurice , Scheepers Peer 
Published: August 2022

Abstract
While there is a substantive literature on the link between welfare states and individuals’ trust, little is known about the micro-linkage of the conditionality of welfare as a driver of trust. This study presents a unique randomized social experiment investigating this link. Recipients of the regular Dutch social assistance policy are compared to recipients of two alternative schemes inspired by the basic income and based on a more trusting and unconditional approach, testing the main reciprocity argument in the literature: a trusting government will harvest trust from welfare recipients in return. Particularly trust in local government – the level at which the experiment was implemented – increases among recipients of the alternative treatments. Subsequently, we innovatively theorize and test rigorously which mediating mechanisms might explain this increase. Policy evaluation, social integration, and psychological well-being are studied in this respect. Of these, the only underlying mechanism proven to mediate the treatment effect in local political trust, is citizens’ satisfaction with policy.
A method to detect sleep apnea using residual attention mechanism network from single-lead ECG signal
Authors: Wang Tao , Lu Changhua , Sun Yining , Fang Hengyang , Jiang Weiwei , Liu Chun 
Published: August 2022

Abstract
Sleep apnea is a sleep disorder caused by weakened or suspended breathing during sleep, which seriously affects the work and health of patients. The traditional polysomnography (PSG) detection process is complicated and expensive, which has attracted researchers to explore a rapid detection method based on single-lead ECG signals. However, existing ECG-based sleep apnea detection methods have certain limitations and complexities, mainly relying on human-crafted features. To solve the problem, the paper develops a sleep apnea detection method based on a residual attention mechanism network. The method uses the RR interval signal and the R-peak signal derived from the ECG signal as input, realizes feature extraction through the residual network (ResNet), and adds the SENet attention mechanism to deepen the mining of channel features. Experimental results show that the per-segment accuracy of the proposed method can reach 86.2%. Compared with existing works, its accuracy has increased by 1.1–8.1%. These results show that the proposed residual attention network can effectively use ECG signals to quickly detect sleep apnea. Meanwhile, compared with existing works, the proposed method overcomes the limitations and complexity of human-crafted features in sleep apnea detection research.
Effect of annealing temperature on the structure and properties of FeCoCrNiMo high-entropy alloy
Authors: Sheng Lei , Zhengwei Xue , Yafeng Liu , Yun Li , Dongsheng Jiang , Ping Wang 
Published: August 2022

AbstractFeCoCrNiMo high-entropy alloy was melted by vacuum arc melting. The alloys were vacuum annealed at 873, 1,073, and 1,273 K, respectively. X-ray diffractometer (XRD), scanning electron microscope (SEM), simultaneous thermal analyzer, microhardness tester, and universal testing machine were used to study the microstructure, the thermal stability, hardness and compression mechanics of as-cast and annealed FeCoCrNiMo alloys. The results show that the alloy is composed of face-centered cubic (FCC) phase and σ phase in both as-cast and annealed states, and the σ phase and μ phase can maintain structural stability at 873 K annealing temperature. The μ phase decomposes to form the σ phase after annealing at 1,073 K, and part of the σ phase dissolves in the FCC phase when annealed at 1,273 K. Both the as-cast and annealed alloys have a typical dendritic structure. The σ phase is enriched in dendrites, and the FCC phase exists between the dendrites. The microstructure of the alloys in the annealed state is more refined than that of the alloy in the as-cast state. In the 1,073 K annealed state, the FeCoCrNiMo alloy has the highest hardness, yield strength, and fracture strength. The fracture mechanism of the alloy is intergranular brittle fracture and cleavage fracture.
