Authors: Rolke Laura J , Griffin Sarah F , Hamilton Joel , Mayo Rachel , Williams Joel E , Rennert Lior , Sease Kerry K
Published: April 2022

Determinants of pediatric asthma management include child, family, healthcare, and community factors. The purpose of this study is to investigate how parents/guardians are impacted by and act on these factors to aid in their child’s asthma self-management. Interviews were conducted in Fall 2020 with 12 female parents/guardians of Black/African American children who participated in a community paramedic pilot study with their child in South Carolina. Children in the initial study had an asthma diagnosis of moderate persistent asthma, had Medicaid insurance, and were determined high-risk for emergency room presentation. Inductive and deductive qualitative analysis identified that child management self-efficacy and independence, parent/guardian health literacy, parent and child negative experiences related to asthma diagnosis and management, asthma management tools, and social support from multiple sources impact child self-management. Findings from this study highlight the importance of clear asthma education and management tool recommendations from healthcare and community providers, particularly for parents/guardians with low health literacy. Health literacy impacted parental responses and likely how families comprehend Medicaid and clinical asthma guidance.
Dalit-Renaissance in Bengal: Relocating Namasudras’ Literature and Culture in Colonial Bengal
Authors: Ansary Mustakim
Published: April 2022

The present essay investigates how the monolithic and mono-dimensional aspect of the Bengal-Renaissance which was pioneered and vanguarded by the so called upper-caste people somehow failed to address and attest crucial issues and multiple voices of the lower castes and other depressed and dispossessed people of Bengal province. One of the central postulates of this article is to foreground and put forward countless measures initiated by the Namasudra community in colonial Bengal through their socio-political and cultural assertions. It further critically engages with an investigative reading of existing archives and historiographies of Bengal that tend to explicate Namasudras’ ideological aspiration and identity consciousness as inseparable and integrative within the hegemonic dominance of upper-castes’ framework. Hence, it intends to provide a counter analysis against this approach by mapping countless Dalit political imaginative manifestos embedded within Namasudra movement during the latter half of the nineteenth century in undivided colonial Bengal province. The primary concern of this article, therefore, is to locate their sociocultural reform movement and other perceptions by tracing their fundamental texts— Sri Sri Harileelamrita and Sri Sri Guruchand Charita, Namasudras’ tracts, booklets, and their festivities, kabigaan, Harisangeet, and so on.

Published: April 2022

Posttraumatic stress disorder (PTSD) is a prevalent psychiatric disorder that can result from experiencing traumatic events. Accurate diagnosis and optimal treatment strategies can be difficult to achieve, due to the heterogeneous etiology and symptomology of PTSD, and overlap with other psychiatric disorders. Advancing our understanding of PTSD pathophysiology is therefore critical. While functional connectivity alterations have shown promise for elucidating the neurobiological mechanisms of PTSD, previous findings have been inconsistent. Eleven patients with PTSD in our first cohort (PTSD-A) and 11 trauma-exposed controls (TEC) underwent functional magnetic resonance imaging. First, we investigated the intrinsic connectivity within known resting state networks (eg, default mode, salience, and central executive networks) previously implicated in functional abnormalities with PTSD symptoms. Second, the overall topology of network structure was compared between PTSD-A and TEC using graph theory. Finally, we used a novel combination of graph theory analysis and scaled subprofile modeling (SSM) to identify a disease-related, covarying pattern of brain network organization. No significant group differences were found in intrinsic connectivity of known resting state networks and graph theory metrics (clustering coefficients, characteristic path length, smallworldness, global and local efficiencies, and degree centrality). The graph theory/SSM analysis revealed a topographical pattern of altered degree centrality differentiating PTSD-A from TEC. This PTSD-related network pattern expression was additionally investigated in a separate cohort of 33 subjects who were scanned with a different MRI scanner (22 patients with PTSD or PTSD-B, and 11 healthy trauma-naïve controls or TNC). Across all participant groups, pattern expression scores were significantly lower in the TEC group, while PTSD-A, PTSD-B, and TNC subject profiles did not differ from each other. Expression level of the pattern was correlated with symptom severity in the PTSD-B group. This method offers potential in developing objective biomarkers associated with PTSD. Possible interpretations and clinical implications will be discussed.

Published: April 2022

Background:

Given that unilateral branch retinal vein occlusion (BRVO) and glaucoma share common systemic vascular risk factors, the fellow eyes of patients with BRVO may be at increased risk of glaucoma.

Objectives:

To analyze the radial peripapillary capillary density (RPCD) in eyes with unilateral BRVO and their unaffected fellow eyes using optical coherence tomography angiography (OCTA).

Design:

Cross-sectional, prospective study.

Methods:

The study included 120 eyes of 80 patients: 40 affected eyes of BRVO, 40 fellow eyes of BRVO, and 40 control eyes. The RPCD, retinal nerve fiber layer thickness (RNFLT) were analyzed using OCTA.

Results:

RPCDs in the whole image, peripapillary region, all the hemispheres, and quadrants were statistically lower in the affected eyes than in both the fellow and control eyes ( p < 0.05 for all). RPCD values in the whole image and the peripapillary region were significantly lower in the fellow eyes than in the control eyes ( p = 0.013, and p = 0.021, respectively). RNFLTs in the peripapillary region, inferior hemisphere and inferior quadrant were significantly lower in the affected eyes than in the control eyes ( p < 0.05 for all). No significant differences were detected between the fellow eyes and the control eyes in term of RNFLT values in any regions ( p > 0.05 for all).

Conclusion:

Lower RPCD values despite similar RNFLT values were observed in the fellow eyes of patients with unilateral BRVO compared with healthy controls. These results may indicate the shared vascular mechanisms and risk factors that account for the development of BRVO and glaucoma.
Chronic condition clusters and associated disability over time
Authors: Klinedinst Tara C , Terhorst Lauren , Rodakowski Juleen
Published: April 2022

Objectives

Recent evidence shows that more complex clusters of chronic conditions are associated with poorer health outcomes. Less clear is the extent to which these clusters are associated with different types of disability (activities of daily living (ADL) and functional mobility (FM)) over time; the aim of this study was to investigate this relationship.

Methods

This was a longitudinal analysis using the National Health and Aging Trends Study (NHATS) ( n = 6179). Using latent class analysis (LCA), we determined the optimal clusters of chronic conditions, then assigned each person to a best-fit class. Next, we used mixed-effects models with repeated measures to examine the effects of group (best-fit class), time (years from baseline), and the group by time interaction on each of the outcomes in separate models over 4 years.

Results

We identified six chronic condition clusters: Minimal Disease, Cognitive/Affective, Multiple Morbidity, Osteoporosis, Vascular, and Cancer. Chronic condition cluster was related to ADL and FM outcomes, indicating that groups experienced differential disability over time. At time point 4, all chronic condition groups had worse FM than Minimal Disease.

Discussion

The clusters of conditions identified here are plausible when considered clinically and in the context of previous research. All groups with chronic conditions carry risk for disability in FM and ADL; increased screening for disability in primary care could identify early disability and prevent decline.

Published: April 2022

Background

B-cell precursor acute lymphoblastic leukemia (BCP-ALL) is a genetically heterogenous malignancy with poor prognosis in relapsed adult patients. The genetic basis for relapse in aneuploid subtypes such as near haploid (NH) and high hyperdiploid (HeH) BCP-ALL is only poorly understood. Pathogenic genetic alterations remain to be identified. To this end, we investigated the dynamics of genetic alterations in a matched initial diagnosis-relapse (ID-REL) BCP-ALL cohort. Here, we firstly report the identification of the novel genetic alteration CYB5Aalt, an alternative transcript of CYB5A, in two independent cohorts.

Methods

We identified CYB5alt in the RNAseq-analysis of a matched ID-REL BCP-ALL cohort with 50 patients and quantified its expression in various molecular BCP-ALL subtypes. Findings were validated in an independent cohort of 140 first diagnosis samples from adult BCP-ALL patients. Derived from patient material, the alternative open reading frame of CYB5Aalt was cloned (pCYB5Aalt) and pCYB5Aalt or the empty vector were stably overexpressed in NALM-6 cells. RNA sequencing was performed of pCYB5Aalt clones and empty vector controls followed by differential expression analysis, gene set enrichment analysis and complementing cell death and viability assays to determine functional implications of CYB5Aalt.

Results

RNAseq data analysis revealed non-canonical exon usage of CYB5Aalt starting from a previously undescribed transcription start site. CYB5Aalt expression was increased in relapsed BCP-ALL and its occurrence was specific towards the shared gene expression cluster of NH and HeH BCP-ALL in independent cohorts. Overexpression of pCYB5Aalt in NALM-6 cells induced a distinct transcriptional program compared to empty vector controls with downregulation of pathways related to reported functions of CYB5A wildtype. Interestingly, CYB5A wildtype expression was decreased in CYB5Aalt samples in silico and in vitro. Additionally, pCYB5Aalt NALM-6 elicited a more resistant drug response.

Conclusions

Across all age groups, CYB5Aalt was the most frequent secondary genetic event in relapsed NH and HeH BCP-ALL. In addition to its high subgroup specificity, CYB5Aalt is a novel candidate to be potentially implicated in therapy resistance in NH and HeH BCP-ALL. This is underlined by overexpressing CYB5Aalt providing first evidence for a functional role in BCL2-mediated apoptosis.

Authors: Ma Liang , Qin Geng , Gai Fei , Jiang Yongwei , Huang Zhan , Yang Hui , Yao Shukun , Du Shiyu , Cao Yongtong
Published: April 2022

Background

Methylated SDC2 has been proved as a diagnostic marker for human colorectal cancer (CRC), noninvasive stool DNA-based methylation testing also emerges as a novel approach for detecting CRC. The aim of this study was to evaluate the clinical performance of stool DNA-based SDC2 methylation test by a new qPCR detection reagent for early detection of CRC.

Methods

A new qPCR detection reagent contained two differentially methylated regions in SDC2 CpG islands for the detection of CRC was used in this study. Performance of the SDC2 methylation detection reagent was evaluated by analyzing limit of detection, precision, and specificity. The effect of interfering substances on assay performance was also tested. 339 subjects (102 CRC patients, 50 patients with advanced adenomas, 39 patients with non-advanced adenomas, 18 colitis patients and 130 normal individuals) from the China-Japan Friendship Hospital were evaluated. Approximately 2.5 g of stool sample was collected from each participant. Stool DNA was extracted and bisulfite-converted, followed by qPCR assay, which contained two pairs of primers for the methylation detection of two fragments of the SDC2 gene (named SDC2-A and SDC2-B). The diagnostic value of this test in CRC was evaluated by calculating receiver operating characteristic (ROC) curve, and value of the area under the curve (AUC).

Results

The test kit was able to detect methylated SDC2 in stool DNA samples with concentrations as low as 90 copies/μL in 100% of replicates. The sensitivity for detecting CRC by methylated SDC2-A alone was 85.29% (95% CI 77.03–91.00%) with a specificity of 96.15% (95% CI 91.08–98.58%). The sensitivity by methylated SDC2-B alone was 83.33% (95% CI 74.82–89.42%) with a specificity of 97.69% (95% CI 93.14–99.51%). However, when methylated SDC2-A and methylated SDC2-B were combined, the sensitivity for CRC detection improved to 87.25% (95% CI 79.27–92.53%) with a specificity of 94.62% (95% CI 89.11–97.56%). Further, the detection reagent achieved ROC-AUC 0.874 (95% CI 0.822–0.927) for SDC2-A, 0.906 (95% CI 0.859–0.952) for SDC2-B, and 0.939 (95% CI 0.902–0.977) for SDC2-Combine A&B.

Conclusions

This study validated the capability of stool DNA-based SDC2 methylation test for early screening of CRC, and combined detection of two fragments of SDC2 gene could improve detection sensitivity.

Authors: Huang Liang , Luo Shuangling , Lai Sicong , Liu Zhanzhen , Hu Huanxin , Chen Mian , Kang Liang
Published: April 2022

Purpose

The prognostic value of the mucinous adenocarcinoma histotype on the early stages especially for stage I colorectal cancer (CRC) is still unclear. This study determined the clinicopathologic characteristics and long-term outcome of stage I colorectal mucinous adenocarcinomas (MAC).

Methods

Among the total of 530 patients with stage I CRC (58 having MAC and 472 having non-MAC) who underwent radical resection, the correlation between clinicopathological factors and MAC was analyzed. Multivariate analysis was performed to determine whether mucinous histotype itself was an independent prognostic impact in stage I patients.

Results

MACs were observed more frequently located in the colon than rectum (p = 0.049), more frequently displayed the deficient mismatch repair (dMMR) phenotype (p = 0.001) and had a greater frequency of T2 stage (p = 0.002). The rate of recurrence was 15.3% and the mortality was 9.2% among all stage I CRC patients. There was no difference in disease-free survival and overall survival between MACs and non-MACs. On multivariate analysis, older age (p = 0.009, hazard ratio: 2.22), rectal cancer (p = 0.008, hazard ratio: 3.21), lymphovascular invasion (LVI) (p < 0.001, hazard ratio: 6.28), and deficient mismatch repair (dMMR) phenotypes (p = 0.044, hazard ratio: 2.62) were independently associated to poor survival of stage I CRC. A high carcinoembryonic antigen level (p = 0.034, hazard ratio: 1.86), rectal cancer (p = 0.035, hazard ratio: 1.81), LVI (p = 0.002, hazard ratio: 3.59) and dMMR phenotypes (p = 0.009, hazard ratio: 2.85) were independently related to short disease-free survival of stage I CRC.

Conclusions

Compared with non-MAC, MAC patients had more T2 patients and more dMMR phenotypes in stage I CRC at presentation, but the mucinous histology is not a significant predictor of recurrence and prognosis in stage I CRC.
Effect of semi-recumbent vibration exercise on muscle outcomes in older adults: a pilot randomized controlled clinical trial
Authors: Taani Murad H. , Binkley Neil , Gangnon Ronald , Krueger Diane , Buehring Bjoern
Published: April 2022

Background

Many older adults with physical limitations living in residential care apartments are unable to exercise in a standing position and are at risk for declining in muscle function leading to falls and injury. Novel approaches to achieve exercise benefits are needed. The purpose of this study was to test the effect of semi-recumbent vibration exercise on muscle outcomes in older adults living in residential care apartment complexes (RCACs).

Methods

A randomized, crossover design was used to examine the effect of semi-recumbent vibration exercise on muscle function and mass among 32 RCAC residents (mean age 87.5 years) with physical limitations. Participants received a randomized sequence of two study conditions: sham or vibration for 8 weeks each separated by a 4-week washout. Before and after the 8 weeks of vibration treatment and sham treatment, muscle mechanography was used to assess muscle function including jump power, weight-corrected jump power, and jump height. Short physical performance battery (SPPB) and handgrip strength were also used to measure muscle function. Bioelectrical impedance spectroscopy was used to estimate skeletal muscle mass. The effect of the vibration treatment on muscle outcomes was analyzed through mixed effects linear regression models.

Results

Vibration exercise leads to better jump height (p < .05) compared to sham exercise but also poorer chair rise performance (p = 0.012). Other muscle functions tests and muscle mass parameters showed non-significant changes.

Conclusion

This small pilot study showed no conclusive results on the effect of semi-recumbent vibration exercise on muscle function and mass in older adults living in RCAC. However, the promising signals of improved jump performance could be used to power larger studies of longer duration with various vibration doses to determine the benefit of vibration exercise in this physically impaired, high-risk population with few exercise capabilities.

Trial registration

The study is registered at clinicaltrials.gov (NCT02533063; date of first registration 26/08/2015).

Authors: Zhao Huiyu , Li Hongqiu , Liang Shuo , Wang Xinyue , Yang Feng
Published: April 2022

Background

We aimed to analyze the distribution of knee cartilage degeneration in young patients with mild symptoms using quantitative magnetic resonance imaging (MRI) T2 mapping.

Materials and methods

This study included sixty six patients (case group) and twenty eight healthy volunteers (control group). The participants underwent 3.0 T conventional MRI plus a multi-echo sequence. The cartilage of each participant was divided into twenty eight subregions. We then calculated the T2 mean values and standard deviation or median and quartile range for each subregion according to whether the normal distribution was satisfied. Besides, we employed Kruskal–Wallis test to determine the statistical differences of each subregion in the control group while the Mann–Whitney U test was used to define the statistical difference between the case group and the control group and between the control group and subjects aged less than or equal to 35 years in the case group.

Results

In the case group, age of 30 male patients was 31.5 ± 9.3 and age of 36 female patients was 35.7 ± 8.3. In the two groups, the superficial central lateral femoral region exhibited relatively high T2 values (control/case group: 49.6 ± 2.7/55.9 ± 8.8), and the deep medial patellar region exhibited relatively low T2 values (control/case group: 34.2 ± 1.3/33.5(32.2, 35.5)). Comparison of the T2 values between the case and the control group demonstrated a statistically significant increase in nine subregions (P1 < 0.05) and there were five subregions in the case group with age ≤ 35 years (P2 < 0.05). In particular, the p-values for four subregions of the patellofemoral joint were all less than 0.05 (P1 = 0.002, 0.015, 0.036, 0.005).

Conclusion

T2 values of patients were significantly different with values of healthy groups, especially in the superficial cartilage of the patellofemoral joint. It made T2 mapping helpful to early identify patients with knee cartilage degeneration.
Impact of klotho on the expression of SRGAP2a in podocytes in diabetic nephropathy
Authors: Jin Donghua , Jia Miao , Xie Yuxian , Lin Lihua , Qiu Hong , Lu Guoyuan
Published: April 2022

Background

Diabetic nephropathy (DN) is the major cause of kidney failure, and glomerular podocytes play critical roles in the pathogenesis of DN by maintaining the glomerular structure and filtration barrier. Klotho and Slit-Robo GTP activating protein 2a (SRGAP2a) have been indicated to play protective roles in reducing kidney injury, but whether there is an internal relationship between these two factors is unclear.

Methods

In this study, we cultured differentiated rat podocytes in vitro and measured the SRGAP2a expressions by immunofluorescence staining, quantitative real-time PCR (qRT-PCR) and western blotting, after siRNA-mediated transforming growth factor β1 (TGF-β1) silencing, TGF-β1 overexpression and in the presence of a reactive oxygen species (ROS) inhibitor. And we detected the expressions of SRGAP2a, small mother against decapentaplegic (Smad)2/3, phosphorylated-Smad2/3 (p-Smad2/3), Smad7, and NAD(P)H oxidase 4 (NOX4), ROS levels and podocyte cytoskeletal remodelling under high glucose (HG) and exogenous klotho conditions. In addition, we performed haematoxylin–eosin (HE) staining and immunohistochemistry with diabetic rat models to confirm the in vitro results.

Results

The results indicated that SRGAP2a expression was significantly upregulated under siRNA-mediated TGF-β1 silencing conditions or after adding a ROS inhibitor, but significantly downregulated with TGF-β1 overexpression, in the presence of HG. The supplementation of exogenous klotho under HG conditions significantly increased the SRGAP2a expression, remodelled the actin cytoskeleton and altered the expressions of Smad2/3, p-Smad2/3, Smad7 and NOX4 and reduced the ROS generation in podocytes. Moreover, klotho administration protected kidney injury in DN rats.

Conclusions

This study indicated that klotho may modulate the expression of SRGAP2a by regulating the ROS and TGF-β1 signalling pathways and provided theoretical support for klotho protein as a novel therapeutic strategy for treating DN patients.
Resolution of severe eosinophilic peritonitis in a patient on continuous ambulatory peritoneal dialysis by changing from Dianeal peritoneal dialysis solution to Stay-Safe Balance solution: a case report
Authors: Chan Zi , Hui Yun Ho , Wong Sunny Sze Ho
Published: April 2022

Background

Eosinophilic peritonitis is a well-known complication at the initiation of peritoneal dialysis. It is often due to an allergic reaction to peritoneal dialysis solution or sometimes to the peritoneal dialysis catheter itself. Most cases are self-limiting with expected spontaneous resolution within a few weeks. Treatment is necessary for severe or persistent cases. However, the optimal treatment has not yet been defined. There have been only a few case reports on the use of anti-histamines and/or steroids for the treatment of eosinophilic peritonitis. We reported a case of severe eosinophilic peritonitis successfully treated by switching the brand of peritoneal dialysis fluid (same glucose concentration). To the best of our knowledge, this is the first reported case employing such a treatment strategy.

Case presentation

An eighty-two-year-old man with end-stage renal failure was started on continuous ambulatory peritoneal dialysis with Dianeal® (Baxter) peritoneal dialysis solution. He developed eosinophilic peritonitis 19 days after initiation of peritoneal dialysis. Infectious causes were ruled out by bacterial, fungal and tuberculosis smears and cultures. In view of the persistent and severe symptoms, we intervened by switching from Dianeal® (Baxter) peritoneal dialysis solution to Stay-Safe Balance® (Fresenius) solution with the same glucose concentration. His eosinophilic peritonitis resolved 5 days after switching the peritoneal dialysis solution.

Conclusion

In severe or persistent cases of eosinophilic peritonitis requiring treatment, other than the use of steroids and anti-histamines, switching to a different brand of peritoneal dialysis solution can be considered.
Sunitinib-related high-grade proteinuria and allograft dysfunction in a kidney recipient: a rare case report
Authors: Ko Hsu-Cheng , Lee Huai-Pao , Wu Jiann-Der , Ma Tsung-Liang , Shen Cheng-Huang , Lin Chang-Te , Cheng Ming-Chin , Jou Yeong-Chin
Published: April 2022

Background

Sunitinib-induced high-grade proteinuria and irreversible renal allograft dysfunction are rare conditions. Here, we present a patient who had received renal allograft and later developed metastatic clear cell renal cell carcinoma(cc-mRCC), for which he was prescribed sunitinib. High-grade proteinuria, hypoalbuminemia, peripheral edema and renal allograft dysfunction (manifesting as an increase in the serum creatinine concentration) occurred 5 months after sunitinib prescription.

Case presentation

The patient was a 58-year-old male who had end-stage renal disease with regular hemodialysis through arteriovenous fistula for 17 years since 1998 and received a renal allograft from a deceased kidney donor in 2015. Unfortunately, in 2019, the patient developed cc-mRCC originating from the left native kidney. We suggested a needle biopsy on left native kidney or radical left nephrectomy, but the patient refused. Sunitinib was prescribed. Follow-up urine analysis showed proteinuria (500 mg/dL) 2 weeks after sunitinib prescription. He was hospitalized 5 months later because of body weight gain, decreased urine output, pitting edema of both lower extremities, and shortness of breath. The image studies showed progression in his cc-mRCC. His serum creatinine level and spot urine protein at admission increased to 4.26 mg/dL and 300 mg/dL, respectively. He agreed on a biopsy for the renal allograft and the pathology studies showed focal segmental glomerulosclerosis, acute interstitial nephritis, and acute tubular injury. Based on the time sequence of clinical presentations with the laboratory and pathological findings, sunitinib-induced renal allograft dysfunction secondary to high-grade proteinuria was most likely. Despite of discontinuation of sunitinib and increased dose of everolimus, renal impairment progressed. Thus, he had to receive hemodialysis starting 2 week after hospitalization. Unfortunately, the patient died of advanced metastasis despite of aggressive medical treatments 3 weeks after admission.

Conclusion

This case report is a reminder that renal allograft dysfunction can happen secondary to proteinuria after taking sunitinib. Hence, clinicians must regularly check renal function and urine protein for renal allograft recipients. Monitoring and modifying drug prescription, especially sunitinib, is necessary if persistent proteinuria accompanied by deteriorating serum creatinine level occurs. Renal biopsy may be considered if more evidence is required to make a differential diagnosis.
The effect of peer education based on Pender’s health promotion model on quality of life, stress management and self-efficacy of patients with multiple sclerosis: a randomized controlled clinical trial
Authors: Bijani Mostafa , Niknam Maryam , Karimi Shanaz , Naderi Zeinab , Dehghan Azizallah
Published: April 2022

Background

As a chronic, disabling disease, multiple sclerosis (MS) has challenged healthcare systems in many ways. MS adversely affects patients’ quality of life and self-efficacy and results in psychological stress. The present study was conducted to investigate the effect of peer education based on Pender’s health promotion model on the quality of life, stress management, and self-efficacy of patients with MS in the south of Iran.

Methods

The present study was a randomized controlled clinical trial. A total of 90 patients were divided into group A intervention group 45 patients) and group B (control group 45 patients). The intervention was peer education based on Pender’s health promotion model. Data were collected using the MS Quality of Life Scale, the Self-efficacy Scale, and the Stress Management Scale. Data analyses were conducted using SPSS version 22. To analyze the data, we used descriptive statistics. Thus, inferential statistics applied included Chi-square, independent-samples t-test, and Repeated measures (ANOVA). The significance level was considered p < 0.05.

Results

The quality of life, self-efficacy, and stress management mean scores of the intervention group as measured immediately and 3 months after intervention were significant (p < 0.05). As for the control group, however, the difference was not significant.

Conclusion

Peer education based on Pender’s health promotion model improves patients’ quality of life, stress management, and self-efficacy with multiple sclerosis. Nursing managers and health system policymakers can use this educational approach for patients with other chronic diseases to enhance their quality of life and self-efficacy.

Long-term surgical outcomes and prognostic factors of foveal detachment in pathologic myopia: based on the ATN classification
Authors: Feng Jingyang , Yu Jiayi , Chen Qiuying , Zhou Hao , Chen Fenge , Wang Weijun , Xu Xun , Fan Ying
Published: April 2022

Background

To investigate the long-term surgical outcomes and prognostic factors of foveal detachment (FD) in pathological myopia.

Methods

This retrospective observational study included 59 patients with FD (61 eyes) who underwent pars plana vitrectomy at Shanghai General Hospital between June 2017 and July 2018 with follow-up for at least 24 months. Comprehensive ophthalmic examinations, including best-corrected visual acuity (BCVA) and swept-source optical coherence tomography, were assessed. Preoperative myopic maculopathy was evaluated according to the ATN classification.

Results

FD completely resolved in 59 of 61 eyes (96.7%). Mean duration of retinal reattachment was 12.10 ± 8.10 months. Mean logMAR BCVA improved from 1.34 ± 0.52 to 0.83 ± 0.43 at 24 months postoperatively (P < 0.001). Secondary macular hole occurred in 8 eyes (13.1%) with a mean period of 3.4 ± 4.1 weeks after primary surgery. In regression analyses, baseline myopic atrophy maculopathy (MAM) (B = 0.213, P = 0.005) and vitreomacular traction (VMT) (B = 0.292, P = 0.007) were adverse prognostic factors for postoperative BCVA. A more severe MAM revealed a delay in retinal reattachment (B = 5.670, P = 0.002). FD eyes with VMT (OR = 1.309, P = 0.003) or outer lamellar macular hole (O-LMH) (OR = 1.369, P < 0.001) were risk factors for postoperative secondary macular hole.

Conclusions

Vitrectomy was effective in the long-term for treating FD. Careful consideration is needed for those with VMT or O-LMH due to the high risk of secondary macular hole after vitrectomy. FD eyes with more severe MAM tended to have poorer postoperative BCVA and extended periods of retinal reattachment.
Comparison of different pupil dilatation methods for phacoemulsification in eyes with a small pupil
Authors: Wang Jin Da , Zhang Jing Shang , Li Meng , Mao Ying Yan , Mayinuer Yusufu , Wan Xiu Hua
Published: April 2022

Purpose

To compare 6 methods for intraoperative pupil dilatation in eyes with insufficient pupil size during phacoemulsification.

Methods

This was a prospective case–control study. 99 microcoria cataract patients (120 eyes) were collected and were divided into 6 groups(20 eyes each group), and their pupils were dilated by bimanual stretching pupil (group I), pupil radial cut open(group II), mechanical pupil dilatation with iris-retractor hooks (group III), OASIS iris expander (group IV), and Malyguin-ring (Microsurgical company, America) (group V), B-HEX Pupil Expander (Med Invent Devics, India)(group VI),respectively. 3.0 mm clear corneal incision were used in phacoemulsification. All cases were followed up at 1 week and 1, 3, 6 months after the surgery. The best corrected visual acuity (BCVA), intraocular pressure(IOP), corneal endothelium cell density(ECD), pupil diameter(PD) of before and after surgery were compared.

Results

One same doctor finished all cataract surgeries successfully. The eyes’ condition before surgery and at 6 months after surgery were compared. There were no significant statistical differences for the conditions of the eyes before surgery among six groups. The ECDs were better at 6 months postoperatively in group III and V, median values: 2114/mm2, 1961/mm2. PD was largest in group II (median value: 5.5 mm), which was significantly larger than other groups (Padjusted < 0.05).

Conclusions

All 6 methods used in this study were effective for the mechanical dilatation of small pupils and didn’t affect the postoperative visual acuity and intraocular pressure in microcoria cataract phacoemulsification. Iris-retractor hooks and the Malyugin Ring can reduce intraoperative corneal endothelium cell loss. Postoperative PD is larger when the iris was cut open radially.

Published: April 2022

Backround

Diabetic retinopathy is a disease seen with microvascular complications as a result of hyperglycemia and insulin resistance. Alarin and Adipsin are molecules with a role in energy and glucose metabolism. The aim of this study was to determine plasma and aqueous levels of Alarin and Adipsin in patients with and without diabetic retinopathy to evaluate their potential roles in diabetic retinopathy.

Methods

The study included one eye from each of 20 cataract patients without diabetes (C), 20 cataract patients with diabetes and without diabetic retinopathy (DM + C), and 20 cataract patients with diabetes and diabetic retinopathy (DR + C). Plasma and aqueous humour samples were taken from all patients during the cataract operation. Alarin and Adipsin levels were examined with the enzyme-linked immunosorbent assay (ELISA) method.

Results

Both plasma and aqueous Alarin levels were significantly higher in the patients with diabetic retinopathy than in the control group (p < 0.001, p = 0.006). Adipsin levels were found to be significantly higher in plasma in the control group than in the DR + C group and significantly higher in aqueous in the DR + C group than in the control group (p < 0.001, p < 0.001).

Conclusion

These findings suggest that Alarin and Adipsin may play important role in diabetic retinopathy.

Published: April 2022

Background

Despite prison settings presenting opportunities for healthy eating and regular exercise, many incarcerated men supplement prison food with unhealthy snacks and drinks, and are less likely to achieve recommended physical activity guidelines than non-incarcerated men. This paper describes the co-development with prison staff of a healthy lifestyle intervention for delivery to incarcerated men, and feasibility testing of its delivery through prison physical education departments.

Methods

The starting point for intervention development was Football Fans in Training (FFIT), an evidence-based intervention successful in engaging men and supporting them to lose weight, make positive lifestyle changes and maintain these long term. We iteratively tested and adapted FFIT for delivery in prison gym facilities through a four Phase pilot and optimisation study. Methods used to evaluate each phase included: observations of session deliveries; semi-structured interviews with participants; and a focus group/semi-structured interviews with prison Physical Education Instructors (PEIs) who delivered the programme. Data were analysed thematically using the Framework approach. Findings from each phase informed development of the optimised programme.

Results

We iteratively co-developed a healthy lifestyle intervention (known as Fit for LIFE) tailored to the needs of incarcerated men and prison operational constraints. Fit for LIFE comprises elements specifically designed to address common barriers to a healthy lifestyle within prison, including: discussion of healthiest available food choices; trying out different physical activity options in the prison gym; and strategies (such as in-cell workouts) for dealing with prolonged time in cells at evenings/weekends. Weight loss was not always the most valued outcome. Instead, participants cited a wide range of behavioural, physical and mental health improvements as important to them, and were more motivated if they could focus on identifying and achieving personally relevant objectives.

Conclusions

Fit for LIFE is a 10-week, group-based healthy lifestyle programme tailored for delivery to incarcerated men in prison gymnasia. Weekly 90-min sessions include informative and interactive ‘classroom’ activities followed by a practical physical activity training session, often with group activities. Fit for LIFE aims to help incarcerated men to: increase physical activity; reduce sedentary time; eat more healthily; and start and maintain using prison gym facilities with confidence.

Background and purpose

The impact of COVID-19 and its control measures have exacerbated existing mental health conditions. Although the deleterious effects of mental health problems are well known, fewer studies have examined the links between the Social Determinants of Health (SDHs) and depression. This study provides insights into the relationship between SDHs and depression during the first strict lockdown in Spain, which lasted for a period of 7 weeks.

Methods

Fifty-two structured interviews were conducted with people diagnosed with depression during June 2020 in the province of Zaragoza (Spain). Interviews were conducted by telephone due to lockdown constraints. Inductive thematic content analysis was used to explore, develop, and define emergent categories of analysis, which were mapped against the SDH framework.

Results

Listening to people’s experiences of living with depression during lockdown provided insights into their concerns and coping strategies, which are greatly influenced by the conditions in which they live, their job and their age. Examples of these factors include access to and quality of physical spaces, including housing conditions and public spaces for socialising, social support, adverse working conditions which include caring responsibilities, and access to digital technologies and healthcare services.

Conclusion

SDHs have played a fundamental role in shaping people’s health and well-being during the COVID-19 pandemic, and this study has shown that they have a considerable effect on depression outcomes. Governments should consider implementing social welfare programs to tackle both psychosocial problems and material need during crisis situations.
Bioresorbable implants vs. Kirschner-wires in the treatment of severely displaced distal paediatric radius and forearm fractures – a retrospective multicentre study

Published: April 2022

Background

Distal radius fractures are very common in paediatric patients. Severely displaced fractures may require surgical intervention. The gold standard surgical method is percutaneous K-wire osteosynthesis followed by immobilisation. Metal implants can be removed with a second intervention; however, these extra procedures can cause further complications. Several studies confirm the benefits of bioabsorbable implants for paediatric patients. The aim of this retrospective study was to compare the complication rates of displaced distal metaphyseal radius (AO 23r-M/3.1) and forearm (AO 23-M/3.1) fractures in children operated on with K-wires versus a novel technique with bioresorbable implants.

Methods

We retrospectively reviewed 94 patients in three paediatric trauma centres who underwent operations due to severely displaced distal forearm or metaphyseal radial fractures between January 2019 and January 2020. The mean age was 8.23 (ranging from 5–12). 30 patients (bioresorbable group, BR-group) were treated with biodegradable PLGA implants (Bioretec®, ActivaPin®), 40 patients with one or two stainless steel Kirschner-wires (K-wires, Sanatmetal®) which were buried under the skin (KW I-group) and 24 children with K-wires left outside the skin. (KWII. Group). We examined the number of minor and major complications as well as the need for repeated interventions. Follow-up was at least one and half year.

Results

There was no significant difference between the complication rates at the two KW groups (p = 0.241; Cramer’s V = 0.211), while the complication rate of the BR group was significantly lower. (p = 0.049; Cramer’s V = 0.293 and p = 0.002; Cramer’s V = 0.418 respectively). No later than half a year after the injury, no difference was observed between the functional outcomes of the patients in each group. One and a half years after the injury, no signs of growth disturbance were found in any of the children. No second surgical intervention was required in the BR group.

Conclusions

Surgeries with bioresorbable intramedullary implants may have fewer complications than K- wire osteosynthesis in the treatment of severely displaced distal forearm fractures. The benefits are most pronounced in the first six weeks after surgery, reducing the number of outpatient visits and increasing the child's sense of comfort. As no second intervention is required, this can lead to significant cost savings. After half a year, there is no difference in the outcomes between the different surgical treatment strategies.

Published: April 2022

Background

Musculoskeletal disorders are a leading cause of morbidity and the most prevalent source of disability among soldiers. Their high prevalence in armed forces and limited ressources have led to problems related to access to physical rehabilitation care. To increase access, supervised group-based exercise programs for the most prevalent musculoskeletal disorders (low back pain, patellofemoral pain, rotator cuff-related shoulder pain or lateral ankle sprain) have been developed at a Canadian Armed forces (CAF) base, but their effectiveness has not been evaluated. The primary objective of this randomized controlled trial is to evaluate the mid- and long-term effects of these group-based training programs on pain severity and functional limitations, in comparison with usual individual physiotherapy care. Secondary objectives include comparing both interventions in terms of health-related quality of life, pain-related fear, and patients’ satisfaction.

Methods

One hundred and twenty soldiers with a new medical referral for physiotherapy services for one of the four targeted musculoskeletal disorders will be consecutively recruited. They will be randomly assigned to either group-based training program or usual individual physiotherapy care, and will take part in the assigned 12-week intervention. There will be four evaluation sessions over 26 weeks (baseline, week 6, 12 and 26). At each follow-up, functional limitations, pain severity, health-related quality of life and pain-related fears will be assessed. Patients satisfaction with treatment will also be evaluated at the end of the intervention period. Either two-way repeated measures ANOVA will be used to analyse and compare the effects of the interventions.

Discussion

This RCT will determine the effectiveness of group-based training programs compared to usual individual physiotherapy care. This new intervention model could represent an efficient, and more pro-active approach to manage a higher number of soldiers with musculoskeletal disorders. It could improve access to physical rehabilitation care and improve the health of soldiers.

Development and validation of professional competency scale for military nurses: an instrument design study
Authors: Ma Huijuan , Zhu Xiaoli , Zhang Suofei , Huang Jinyu , Lu Ya , Luo Yu
Published: April 2022

Background

Military nurses are expected to be competent in providing quality nursing care in their assigned departments and meeting the medical needs of the military during deployment. Competency assessment is a key step in the development of a robust and competent nursing team. This study was aimed to develop the Professional Competency Scale for Military Nurses (PCSMN) and test its psychometric properties.

Methods

An instrument development and validation study were conducted. Military nurses in military hospitals in eastern, southern, western, and northern China were recruited in this study. The study procedure comprised three main steps: item development (extensive literature review, the Delphi survey, and a pilot test), scale development (item analysis and exploratory factor analysis), and scale validation (confirmatory factor analysis and reliability test).

Results

The 65-item PCSMN comprised four dimensions: clinical nursing knowledge and skills, military nursing knowledge and skills, professional ability, and comprehensive quality. The reliability and validity of the PCSMN were satisfactory, with the above four factors accounting for 66.9% of the total variance.

Conclusion

The PCSMN is a good instrument for evaluating the competencies of military nurses in military hospitals. This may provide guidance for competency-based training.
