Enhanced tolerance to drought stress resulting from Caragana korshinskii CkWRKY33 in transgenic Arabidopsis thaliana
Authors: Li Zhen , Liang Fengping , Zhang Tianbao , Fu Na , Pei Xinwu , Long Yan
Published: March 2021

Background

It is well known that WRKY transcription factors play important roles in plant growth and development, defense regulation and stress responses.

Results

In this study, a WRKY transcription factor, WRKY33, was cloned from Caragana korshinskii. A sequence structure analysis showed that it belonged to the Group-I type. Subcellular localization experiments in tobacco epidermal cells showed the presence of CkWRKY33 in the nucleus. Additionally, CkWRKY33 was overexpressed in Arabidopsis thaliana. A phenotypic investigation revealed that compared with wild-type plants, CkWRKY33-overexpressing transgenic plants had higher survival rates, as well as relative soluble sugar, proline and peroxidase contents, but lower malondialdehyde contents, following a drought stress treatment.

Conclusions

This suggested that the overexpression of CkWRKY33 led to an enhanced drought-stress tolerance in transgenic A. thaliana. Thus, CkWRKY33 may act as a positive regulator involved in the drought-stress responses in Caragana korshinskii.

Isolation of Mycobacterium talmoniae from a patient with diffuse panbronchiolitis: a case report
Authors: Suzuki Tomoko , Saitou Miwako , Igarashi Yuriko , Mitarai Satoshi , Niitsuma Katsunao
Published: March 2021

Background

Mycobacterium (M) talmoniae isolated from a patient with cystic fibrosis was first described in 2017, and cases of M. talmoniae remain exceedingly rare.

Case presentation

A 51-year-old woman had respiratory symptoms for 10 years. Diffuse panbronchiolitis (DPB) was detected at the first visit at our hospital. A cavity lesion in the apex of the left lung was found, and sputum and bronchoalveolar lavage fluid were acid-fast bacillus (AFB) smear- and culture-positive besides Pseudomonas aeruginosa. M. talmoniae was finally identified, and the standard combination therapy for non-tuberculous mycobacteria (NTM) was administered for 2 y referring to the drug-susceptibility test. Thereafter, the AFB culture was negative, the wall thickness of the lung cavity was ameliorated, and oxygen saturation improved.

Conclusions

We encountered a rare case of M. talmoniae with DPB, for which standard combination therapy was effective. M. talmoniae may be considered a potential pathogen of lung disease, especially in patients with bronchiectatic lesions.

Authors: Mirmiran Parvin , Yuzbashian Emad , Rahbarinejad Pegah , Asghari Golaleh , Azizi Fereidoun
Published: March 2021

Background

As chronic kidney disease (CKD) is amongst the current global health challenges, this study is aiming to evaluate the long-term intake of total polyphenol and its subclasses in association with CKD incidence.

Methods

For the purpose of this study, a sample of 3021 Iranian adults (47 % men, aged 20–79 years) with no CKD diagnosis at baseline, were selected from the Tehran Lipid and Glucose Study population. The total intake of polyphenol and its major subclasses were assessed by a validated food frequency questionnaire and categorized as flavonoids, phenolic acids, stilbenes, and lignans. Although the morphological abnormalities of the kidneys or 3-month persistent urinalysis can distinctively define CKD, the glomerular filtration rate (eGFR) reduction is accepted as a more precise index of renal function. Therefore, eGFR < 60 mL/min/1.73m2 was the exclusive index of CKD diagnosis in the current study. The eGFR was calculated by the Modification of Diet in Renal Disease Study equation. Cox-regression analysis was used to assess the hazard ratio and 95 % confidence intervals of CKD in quartiles of the total polyphenols.

Results

In this study, 355 CKD cases over 11,058.464 person-years was reported. The median (IQR) age of participants was 36 years (27–46) at baseline. Moderate intake of lignans (≤ 6.8 mg) was negatively associated with the incidence of CKD in the adjusted model. No significant associations were detected between higher amounts of lignin and total polyphenols (HR: 0.97, 95 % CI 0.67–1.40) and CKD incidence.

Conclusions

Based on the current findings, moderate intake of lignin possess CKD-protective properties by approximately 32 %. No independent associations were observed between higher amounts of lignins and CKD incidence.
Parotid carcinoma following chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids: a case report
Authors: Deng Yilun , Zhao Bi , Wei Bing , Zhang Shihong , Liu Ming
Published: March 2021

Background

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is an inflammatory disorder with unclear causes. Paraneoplastic etiology may be a cause. We report a case of CLIPPERS with parotid carcinoma.

Case presentation

A 54-year-old man with a history of lymphoma was hospitalized with a pontocerebellar syndrome. Brain MRI revealed that the pons and cerebellum were “peppered” with punctate and curvilinear enhancement lesions that supported the diagnosis of CLIPPERS. The relapse of lymphoma was excluded by a further cerebellum biopsy revealing predominantly CD3+ T cells in white matter. The patient was relieved after pulse therapy with intravenous methylprednisolone and a large dose of corticosteroids, but he complained of a worsening gait problem when corticosteroids were tapered to a lower dose. Although the clinical symptoms gradually improved again by increasing the dosage of corticosteroids with Azathioprine, the patient still had a slight unsteady gait during follow-up. At the 7-month follow-up, a parotid mass was detected by MRI and was verified as carcinoma by biopsy. After resection of parotid carcinoma, the residual symptoms and previous MRI lesions disappeared, and no relapse occurred.

Conclusions

CLIPPERS may not be a distinct nosologic entity but an overlapping diagnosis with other diseases. Some cases of CLIPPERS might be a subtype of paraneoplastic neurological syndromes (PNS) due to the similar mechanism of antibody-mediated encephalitis. Tumor screening and serum paraneoplastic autoantibody tests are recommended for patients with CLIPPERS, especially for those who relapse when corticosteroids treatment is stopped or tapered.
Temporal relationship between Women’s empowerment and utilization of antenatal care services: lessons from four National Surveys in sub-Saharan Africa
Authors: Kareem Yusuf Olushola , Morhason-Bello Imran Oludare , OlaOlorun Funmilola M. , Yaya Sanni
Published: March 2021

Background

In November 2016, the WHO four-visit focused antenatal care (FANC) model adopted in sub-Saharan Africa (SSA) was reverted to eight contacts or more as a response to reducing the global perinatal and maternal deaths and in achieving the sustainable development goal (SDG) 3. Women’s empowerment, which connote the social standing, position and the ability of women to make life decisions and choices has been associated with the maternal health seeking behaviour and outcomes. This study examined the association between women’s empowerment and the WHO ANC model of eight visits or more, and early first antenatal visit among pregnant women. In addition, we explored the association between women’s empowerment and the WHO FANC model to allow for comparison for countries that have not adopted the recent WHO ANC model.

Methods

The most recent (2018) Demographic and Health Survey (DHS) datasets conducted in SSA were used for analyses. We used all available indicators of women’s empowerment captured in the DHS. The 30 variables on women’s empowerment were classified into eight components using exploratory factor analysis. We fitted separate ordinal logistic regression to assess association between antenatal care utilization (number of visits and time of first antenatal visit) and women empowerment factors while adjusting for other covariates. Analysis was performed with STATA 15.0 and adjusted for complex survey design, p-value< 0.05 were used for interpretation of results.

Results

The proportion of women who attended eight or more ANC visits were 1.4, 2.7 and 3.5% in Zambia, Guinea and Mali, respectively. Zambia had the lowest prevalence of 8 or more ANC visits also had the highest prevalence of at least 4 visits (63.8%) and early first ANC visit (38.2%), while Nigeria with the highest prevalence of women with at least 8 visits (17.7%) had the lowest prevalence (17.6%) of women that attended ANC visit in their first trimester. Women’s empowerment was associated with more ANC visits and attending first ANC visit in the first trimester. However, these association with the women empowerment components varied significantly across the four SSA countries.

Conclusion

This study highlights the significant impact of women’s empowerment as a key factor for improving maternal health outcomes in SSA. It is imperative that government and development partners invest more on empowerment of women as part of strategic intervention to improve maternal health outcomes.

Published: March 2021

Background

It is still unknown whether the “Somatic symptom disorders (SSD) and related disorders” module of the Structured Clinical Interview for DSM-5, research version (SCID-5-RV), is valid in China. This study aimed to assess the SCID-5-RV for SSD in general hospital outpatient clinics in China.

Methods

This multicentre cross-sectional study was conducted in the outpatient clinics of nine tertiary hospitals in Beijing, Jincheng, Shanghai, Wuhan, and Chengdu between May 2016 and March 2017. The “SSD and related disorders” module of the SCID-5-RV was translated, reversed-translated, revised, and used by trained clinical researchers to make a diagnosis of SSD. Several standardized questionnaires measuring somatic symptom severity, emotional distress, and quality of life were compared with the SCID-5-RV.

Results

A total of 699 patients were recruited, and 236 were diagnosed with SSD. Of these patients, 46 had mild SSD, 78 had moderate SSD, 100 had severe SSD, and 12 were excluded due to incomplete data. The SCID-5-RV for SSD was highly correlated with somatic symptom severity, emotional distress, and quality of life (all P < 0.001) and could distinguish nonsevere forms of SSD from severe ones.

Conclusions

This study suggests that SCID-5-RV for SSD can distinguish SSD from non-SSD patients and severe cases from nonsevere cases. It has good discriminative validity and reflects the DSM-5 diagnostic approach that emphasizes excessive emotional, thinking, and behavioural responses related to symptoms.
Qualitative study exploring the barriers to menstrual hygiene management faced by adolescents and young people with a disability, and their carers in the Kavrepalanchok district, Nepal
Authors: Wilbur Jane , Kayastha Shubha , Mahon Thérèse , Torondel Belen , Hameed Shaffa , Sigdel Anita , Gyawali Amrita , Kuper Hannah
Published: March 2021

Background

Menstrual hygiene management (MHM) is a recognised public health, social and educational issue, which must be achieved to allow the realisation of human rights. People with disabilities are likely to experience layers of discrimination when they are menstruating, but little evidence exists.

Methods

The study aims to investigate barriers to MHM that people with disabilities and their carers face in the Kavrepalanchok, Nepal, using qualitative methods. Twenty people with disabilities, aged 15–24, who menstruate and experience ‘a lot of difficulty’ or more across one or more of the Washington Group functional domains were included, as well as 13 carers who provide menstrual support to these individuals. Purposeful sampling was applied to select participants. Different approaches were used to investigating barriers to MHM and triangulate data: in-depth interviews, observation, PhotoVoice and ranking. We analysed data thematically, using Nvivo 11.

Results

Barriers to MHM experienced by people with disabilities differ according to the impairment. Inaccessible WASH facilities were a major challenge for people with mobility, self-care and visual impairments. People with intellectual impairments had difficulty accessing MHM information and their carers despaired when they showed their menstrual blood to others, which could result in abuse. No support mechanisms existed for carers for MHM, and they felt overwhelmed and isolated. Menstrual discomfort was a major challenge; these were managed with home remedies, or not at all. Most participants followed menstrual restrictions, which were widespread and expected; many feared they would be cursed if they did not. As disability is often viewed as a curse, this demonstrates the layers of discrimination faced.

Conclusion

Issues related to MHM for people with disabilities is more complex than for others in the population due to the additional disability discrimination and impairment experienced. Research exploring these issues must be conducted in different settings, and MHM interventions, tailored for impairment type and carers requirements,should be developed. Attention to, and resourcing for disability inclusive MHM must be prioritised to ensure ‘no one is left behind’.
Fear-of-falling and associated risk factors in persons with rheumatoid arthritis: a 1 year prospective study
Authors: Stanmore Emma K. , Oldham Jackie , Skelton Dawn A. , O’Neill Terence , Pilling Mark , Todd Chris
Published: March 2021

Background

Falls, associated injuries and fear-of-falling are common in adults with RA. Fear-of-falling can be a major consequence of, and as debilitating as falling, resulting in a cycle of activity restriction, reduced quality of life, institutionalisation and potentially increase risk of falls. The objective of this study was to examine the relationship between fear-of-falling and risk factors associated with fear-of-falling in adults with rheumatoid arthritis (RA) over a 1 year period.

Methods

Five hundred fifty-nine patients with RA were recruited from four outpatient clinics in this prospective cohort study. Baseline assessments included socio-demographic, medical and lifestyle related risk factors. Fall incidence was prospectively obtained monthly using postal cards over a 1 year period. Fear-of-falling was assessed at baseline and 1 year using the Short Falls Efficacy Scale-International (Short FES-I). Logistic regression was used to determine the association between high fear-of-falling (Short FES-I > 11) at baseline (outcome) and a range of putative predictor variables including previous falls, and also baseline factors associated with a high fear-of-falling at follow-up.

Results

Five hundred thirty-five (ninety-six percent) participants (mean age 62.1 yrs.; 18–88 yrs) completed 1 year follow-up and of these, 254 (47%) completed the Short FES-I questionnaire at 1 year. In a multivariate model, a history of multiple falls (OR = 6.08) higher HAQ score (OR = 4.87) and increased time to complete the Chair Stand Test (OR = 1.11) were found to be independent predictors of high fear-of-falling and had an overall classification rate of 87.7%. There were no significant differences found in fear-of-falling at 1 year follow-up in those who reported falls during the study, participant’s baseline fear appeared to predict future fear, regardless of further falls.

Conclusions

Fear-of-falling is significantly associated with previous falls and predictive of future falls and fear. RA patients would benefit from fall prevention measures whether or not they have previously fallen.

A systematic review of penile prosthesis infection and meta-analysis of diabetes mellitus role
Authors: Gon Lucas Mira , de Campos Caio César Citatini , Voris Brunno Raphael Iamashita , Passeri Luís Augusto , Fregonesi Adriano , Riccetto Cássio Luís Zanettini
Published: March 2021

Background

Infection is the most feared complication of a penile prosthesis. Diabetes mellitus (DM) is widely known to increase the risk of several infections, but its role in the penile prosthesis is still controversial. This systematic review aims to show the contemporary scenario of penile prosthesis infection and present a meta-analysis about DM contribution to penile prosthesis infection.

Methods

The review was performed with no language or time limitation, including ten databases. The included articles were about the male population who received a penile prosthesis with no model restriction, with a minimum follow up of 1 year, and outcomes adequately reported.

Results

The mean infection incidence of penile prosthesis ranged from 0.33 to 11.4%. In early 2000, the general incidence of infection was 3 to 5%, then, the introduction of coated materials decreased it to 0.3 to 2.7%. The meta-analysis showed that diabetes mellitus is related to an increased risk of penile prosthesis infection with an odds ratio of 1.53 (95% CI 1.15–2.04).

Conclusions

Penile prosthesis infection decreased in the last decades but remains a significant cause of reoperation, and it is related to lower prosthesis survival. Meta-analysis concludes that diabetes mellitus is related to a higher risk of penile prosthesis infection.

Published: March 2021

Over the past decade, therapeutic messenger RNAs (mRNAs) have emerged as a highly promising new class of drugs for protein replacement therapies. Due to the recent developments, the incorporation of modified nucleotides in synthetic mRNAs can lead to maximizing protein expression and reducing adverse immunogenicity. Despite these stunning improvements, mRNA therapy is limited by the need for the development of safe and efficient carriers to protect the mRNA integrity for in vivo applications. Recently, leading candidates for in vivo drug delivery vehicles are cell-derived exosomes, which have fewer immunogenic responses. In the current study, the key hurdles facing mRNA-based therapeutics, with an emphasis on recent strategies to overcoming its immunogenicity and instability, were highlighted. Then the immunogenicity and toxicity of exosomes derived from various cell sources were mentioned in detail. Finally, an overview of the recent strategies in using exosomes for mRNA delivery in the treatment of multiple diseases was stated.
The optimal orthodontic displacement of clear aligner for mild, moderate and severe periodontal conditions: an in vitro study in a periodontally compromised individual using the finite element model
Authors: Ma Yanning , Li Song
Published: March 2021

Background

Pathologic tooth migration (PTM) is a common complication of mild to severe periodontitis and proper orthodontic treatment is helpful to alleviate periodontal diseases. The goal of this study is to explore an optimal orthodontic displacement of clear aligner using a three-dimensional (3D) finite element model (FEM).

Methods

The cone beam computed tomography (CBCT) data of a patient received invisible orthodontics without diabetes and other systemic diseases were collected. Based on the new classification scheme for periodontal diseases in 2017 (stage I: mild periodontitis, [M1]; stage II: moderate periodontitis, [M2]; stage III: severe periodontitis, [M3]), 3D-FEMs of mandible were established using MIMICS 10.0 and ABAQUS 6.5 softwares. The 3D stress distribution diagrams and stress value of the teeth (left lower incisor, left lower central incisor, right lower lateral incisor, and right lower central incisor) under three different periodontal conditions (M1, M2, and M3) with axial inclination 90° and 100° were obtained by ABAQUS 6.5.

Results

The stress of anterior teeth was concentrated in the teeth neck, and became greater when the periodontal condition was worse. The stress value of anterior teeth and the strain at the top of the alveolar crest are greater as the displacement increasing. The stress value of anterior teeth and the strain at the top of the alveolar crest in axial inclination 100° are relatively great compared to those of axial inclination 90°. For patients with excessively inclined anterior teeth (such as 100°), the optimal orthodontic displacement is 0.18 mm. In order to ensure that alveolar ridge crest is not deformed, the displacement is less than 0.18 mm (strain for 0.165 mm), 0.15 mm (strain for 0.167 mm) and 0.10 mm (strain for 0.117 mm) respectively when alveolar bone is normal, resorption 1/3 or 1/3–1/2.

Conclusions

The optimal orthodontic displacement for patients (M1, M2, and M3) with excessively inclined anterior teeth (axial inclination 100°) is 0.18 mm. To avoid the strain at the top of the alveolar crest, the optimal displacements for M1, M2 and M3 periodontal disease patients are less than 0.18 mm, 0.15 mm and 0.10 mm, respectively.
How well do documented goals-of-care discussions for patients with stage IV cancer reflect communication best practices?
Authors: Ernecoff Natalie C. , Wessell Kathryn L. , Wood William A. , Winzelberg Gary S. , Collichio Frances A. , Hanson Laura C.
Published: March 2021

Background

Written clinical communication regarding patients’ disease understanding and values may facilitate goal-concordant care, yet little is known about the quality of electronic health record (EHR) documentation. We sought to (1) describe frequency of communication best practices in EHR-documented goals-of-care discussions, and (2) assess whether templated notes improve quality of documentation.

Methods

Researchers pulled text of EHR-documented goals-of-care discussions for hospitalized patients with Stage IV cancer from admission to 60-days follow-up. Text was included when in a single encounter the clinician addressed: (a) prognosis and/or illness understanding; and (b) goals and/or treatment options. Researchers qualitatively coded text based on guidelines for communication best practices, and noted if an EHR template was used.

Results

Forty-two percent (206/492) of patients had EHR-documented goals-of-care discussions. Text frequently described communication of cancer progression (89%), though rarely included prognosis (22%). Text often included patients’ goals and values (83%), and at least on specific treatment decision (82%). Communication about treatments was included for 98% of patients; common examples included cancer treatment (62%), hospice (62%), resuscitation (51%), or intensive care (38%). Clinicians documented making recommendations for 40% of patients. Text addressing patient emotional and spiritual concerns was uncommon (15%). Compared to free text, use of a template was associated with increased documentation of goals and values (80% vs. 61%, p < 0.01), but not other best practices.

Conclusion

Insights from the study can be used to guide future training and research to study and improve the quality of documentation about goal of care, and its impact on goal-concordant care.
Patient perceptions of students in a longitudinal integrated clerkship in Taiwan: a qualitative study
Authors: Chang Yaw-Wen , Hirsh David A. , Fang Wen-Hui , Li Honghe , Tzeng Wen-Chii , Kao Senyeong
Published: March 2021

Background

Longitudinal integrated clerkships (LICs) are a model of clinical education growing rapidly in Western contexts. LICs use educational continuity to benefits students’ clinical learning and professional identity formation. Patient-centered care is a core component of medical professionalism in the West. To support patient-centered care, education leaders in Taiwan restructured clinical education and implemented the first longitudinal integrated clerkship in East Asia. We aimed to investigate patients’ perceptions of longitudinal relationships with the LIC students within Taiwan’s Confucian cultural and social context.

Methods

We invited patients or their family members who were cared for longitudinally by a LIC student to participate in the study. Participating patients or their family members undertook semi-structured interviews. We analyzed data qualitatively using a general inductive approach to identify themes in the patients’ descriptions of their experiences interacting with the LIC students.

Results

Twenty-five patients and family members participated in interviews: 16 patients and 9 family members. Qualitative analysis of interview transcripts identified three themes from patients’ experience receiving care from their LIC students: care facilitation, companionship, and empathy. To provide care facilitation, LIC students served as a bridge between the physicians and patients. Students served patients by reminding, consulting, tracking disease progression, and researching solutions for problems. To provide companionship, students accompanied patients interpersonally like a friend or confidant who listens and provides a presence for patients. To provide empathy, patients reported that students showed sincere concern for patients’ experience, feelings, and mood.

Conclusion

In our study, Taiwanese patients’ perspectives of LIC students suggested the value of care facilitation, companionship, and empathy. We discuss these themes within the context of Confucian culture and the Taiwanese context of care.
The effects of clinical decision support system for prescribing medication on patient outcomes and physician practice performance: a systematic review and meta-analysis
Authors: Taheri Moghadam Sharare , Sadoughi Farahnaz , Velayati Farnia , Ehsanzadeh Seyed Jafar , Poursharif Shayan
Published: March 2021

Background

Clinical Decision Support Systems (CDSSs) for Prescribing are one of the innovations designed to improve physician practice performance and patient outcomes by reducing prescription errors. This study was therefore conducted to examine the effects of various CDSSs on physician practice performance and patient outcomes.

Methods

This systematic review was carried out by searching PubMed, Embase, Web of Science, Scopus, and Cochrane Library from 2005 to 2019. The studies were independently reviewed by two researchers. Any discrepancies in the eligibility of the studies between the two researchers were then resolved by consulting the third researcher. In the next step, we performed a meta-analysis based on medication subgroups, CDSS-type subgroups, and outcome categories. Also, we provided the narrative style of the findings. In the meantime, we used a random-effects model to estimate the effects of CDSS on patient outcomes and physician practice performance with a 95% confidence interval. Q statistics and I2were then used to calculate heterogeneity.

Results

On the basis of the inclusion criteria, 45 studies were qualified for analysis in this study. CDSS for prescription drugs/COPE has been used for various diseases such as cardiovascular diseases, hypertension, diabetes, gastrointestinal and respiratory diseases, AIDS, appendicitis, kidney disease, malaria, high blood potassium, and mental diseases. In the meantime, other cases such as concurrent prescribing of multiple medications for patients and their effects on the above-mentioned results have been analyzed. The study shows that in some cases the use of CDSS has beneficial effects on patient outcomes and physician practice performance (std diff in means = 0.084, 95% CI 0.067 to 0.102). It was also statistically significant for outcome categories such as those demonstrating better results for physician practice performance and patient outcomes or both. However, there was no significant difference between some other cases and traditional approaches. We assume that this may be due to the disease type, the quantity, and the type of CDSS criteria that affected the comparison. Overall, the results of this study show positive effects on performance for all forms of CDSSs.

Conclusions

Our results indicate that the positive effects of the CDSS can be due to factors such as user-friendliness, compliance with clinical guidelines, patient and physician cooperation, integration of electronic health records, CDSS, and pharmaceutical systems, consideration of the views of physicians in assessing the importance of CDSS alerts, and the real-time alerts in the prescription.
Midwives’ experiences of implementing respectful maternity care knowledge in daily maternity care practices after participating in a four-day RMC training
Authors: Dzomeku Veronica Millicent , Boamah Mensah Adwoa Bemah , Nakua Emmanuel Kweku , Agbadi Pascal , Lori Jody R. , Donkor Peter
Published: March 2021

Background

In Ghana, studies documenting the effectiveness of evidence-based specialized training programs to promote respectful maternity care (RMC) practices in healthcare facilities are few. Thus, we designed a four-day RMC training workshop and piloted it with selected midwives of a tertiary healthcare facility in Kumasi, Ghana. The present paper evaluated the impact of the training by exploring midwives’ experiences of implementing RMC knowledge in their daily maternity care practices 4 months after the training workshop.

Methods

Through a descriptive qualitative research design, we followed-up and conducted 14 in-depth interviews with participants of the RMC training, exploring their experiences of applying the acquired RMC knowledge in their daily maternity care practices. Data were managed and analysed using NVivo 12. Codes were collapsed into subthemes and assigned to three major predetermined themes.

Results

The findings have been broadly categorized into three themes: experiences of practising RMC in daily maternity care, health facility barriers to practising RMC, and recommendations for improving RMC practices. The midwives mentioned that applying the newly acquired RMC knowledge has positively improved their relationship with childbearing women, assisted them to effectively communicate with the women, and position them to recognize the autonomy of childbearing women. Despite the positive influence of the training on clinical practice, the midwives said the policy and the built environment in the hospital does not support the exploration of alternative birthing positions. Also, the hospital lacked the required logistics to ensure privacy for multiple childbearing women in the open labour ward. The midwives recommended that logistics for alternative birthing positions and privacy in the ward should be provided. Also, all midwives and staff of the hospital should be taken through the RMC training program to encourage good practice.

Conclusion

Despite the report of some RMC implementation challenges, the midwives noted that the 4-day RMC training has had a positive impact on their maternity caregiving practice in the hospital. Policies and programs aimed at addressing the issue of disrespect and abusive practices during maternity care should advocate and include the building of facilities that support alternative birthing positions and privacy of childbearing women during childbirth.
Opioid use disorder in pregnancy: leveraging provider perceptions to inform comprehensive treatment
Authors: Titus-Glover Doris , Shaya Fadia T. , Welsh Christopher , Qato Danya M. , Shah Savyasachi , Gresssler Laura E. , Vivrette Rebecca
Published: March 2021

Background

Medications for opioid use disorder (MOUD) are recommended with adjuvant behavioral therapies, counseling, and other services for comprehensive treatment of maternal opioid use disorder. Inadequate access to treatment, lack of prescribing providers and complex delivery models are among known barriers to care. Multi-disciplinary provider input can be leveraged to comprehend factors that facilitate or inhibit treatment. The objective of this study is to explore provider perceptions of MOUD and factors critical to comprehensive treatment delivery to improve the care of pregnant women with opioid use disorder.

Methods

A qualitative research approach was used to gather data from individual provider and group semi-structured interviews. Providers (n = 12) responded to questions in several domains related to perceptions of MOUD, treatment delivery, access to resources, and challenges/barriers. Data were collected, transcribed, coded (by consensus) and emerging themes were analyzed using grounded theory methodology.

Results

Emerging themes revealed persistent gaps in treatment and challenges in provider, health systems and patient factors. Providers perceived MOUD to be a “lifeline” to women.

Conclusions

Inconsistencies in treatment provision, access and uptake can be improved by leveraging provider perceptions, direct experiences and recommendations for an integrated team-based, patient-centered approach to guide the care of pregnant women with opioid use disorder.

Authors: Ma Dae Joong , Lee Hyun-Seob , Kim Kwangsoo , Choi Seongmin , Jang Insoon , Cho Seo-Ho , Yoon Chang Ki , Lee Eun Kyoung , Yu Hyeong Gon
Published: March 2021

Background

To date, no genetic analysis of inherited retinal disease (IRD) using whole-exome sequencing (WES) has been conducted in a large-scale Korean cohort. The aim of this study was to characterise the genetic profile of IRD patients in Korea using WES.

Methods

We performed comprehensive molecular testing in 168 unrelated Korean IRD patients using WES. The potential pathogenicity of candidate variants was assessed using the American College of Medical Genetics and Genomics and the Association for Molecular Pathology variant interpretation guidelines, in silico prediction tools, published literature, and compatibility with known phenotypes or inheritance patterns.

Results

Causative variants were detected in 86/168 (51.2%) IRD patients, including 58/107 (54.2%) with retinitis pigmentosa, 7/15 (46.7%) with cone and cone-rod dystrophy, 2/3 (66.6%) with Usher syndrome, 1/2 (50.0%) with congenital stationary night blindness, 2/2 (100.0%) with Leber congenital amaurosis, 1/1 (100.0%) with Bietti crystalline dystrophy, 1/1 (100.0%) with Joubert syndrome, 9/10 (90.0%) with Stargardt macular dystrophy, 1/10 (10.0%) with vitelliform macular dystrophy, 1/11 (9.1%) with other forms of macular dystrophy, and 3/4 (75.0%) with choroideraemia. USH2A, ABCA4, and EYS were the most common causative genes associated with IRD. For retinitis pigmentosa, variants of USH2A and EYS were the most common causative gene mutations.

Conclusions

This study demonstrated the distribution of causative genetic mutations in Korean IRD patients. The data will serve as a reference for future genetic screening and development of treatment modalities for Korean IRD patients.

In Canada, there is longstanding evidence of health inequities for racialized groups. The purpose of this study is to understand the effect of current health care policies and practices on racial/ethnic groups and in particular racialized groups at the level of the individual in Toronto’s health care system.

Methods

This study used a semi-qualitative study design: concept mapping. A purposive sampling strategy was used to recruit participants. Health care users and health care providers from Toronto and the Greater Toronto Area participated in all four concept mapping activities. The sample sizes varied according to the activity. For the rating activity, 41 racialized health care users, 23 non-racialized health care users and 11 health care providers completed this activity. The data analysis was completed using the concept systems software.

Results

Participants generated 35 unique statements of ways in which patients feel disrespect or mistreatment when receiving health care. These statements were grouped into five clusters: ‘Racial/ethnic and class discrimination’, ‘Dehumanizing the patient’, ‘Negligent communication’, ‘Professional misconduct’, and ‘Unequal access to health and health services’. Two distinct conceptual regions were identified: ‘Viewed as inferior’ and ‘Unequal medical access’. From the rating activity, racialized health care users reported ‘race’/ethnic based discrimination or everyday racism as largely contributing to the challenges experienced when receiving health care; statements rated high for action/change include ‘when the health care provider does not complete a proper assessment’, ‘when the patient’s symptoms are ignored or not taken seriously’, ‘and ‘when the health care provider belittles or talks down to the patient’.

Conclusions

Our study identifies how racialized health care users experience everyday racism when receiving health care and this is important to consider in the development of future research and interventions aimed at addressing institutional racism in the health care setting. To support the elimination of institutional racism, anti-racist policies are needed to move beyond cultural competence polices and towards addressing the centrality of unequal power social relations and everyday racism in the health care system.

Background

The Short Form Health Survey (SF-12v2) is an increasingly popular measure of health-related quality of life (HRQoL) in Singapore. In order to examine whether the SF-12v2 was appropriate for use in the population, the factor structure and validity of the English, Mandarin, and Malay versions were assessed in a representative sample of the general population of Singapore.

Methods

6126 respondents were recruited for the Singapore Mental Health Study 2016 (SMHS 2016), a cross-sectional and population-based survey. Confirmatory factor analyses (CFA) were conducted to examine the fit of a two-factor model for the SF-12v2 within a representative sample and amongst the different language (English, Mandarin, Malay) subgroups. Multiple-group CFAs (MGCFA) were conducted to test measurement invariance across the different languages, ethnicities, and chronic illnesses subgroups. CFA-generated latent factor scores (FSCORE command in MPlus) were also compared with the composite scores derived from the developer’s scoring method via correlations. Sociodemographic correlates of the latent physical and mental health scores were explored.

Results

CFA results within the full sample supported a two-factor model (RMSEA = 0.044; CFI = 0.991; TLI = 0.988; SRMR = 0.044) in which physical functioning, role physical, bodily pain and general health items loaded onto a latent physical health factor, while role emotional, mental health, social functioning, and vitality items loaded onto a latent mental health factor. Physical and mental health factors were allowed to correlate, unlike the developer’s orthogonal scoring method. All standardized loadings were high and statistically significant. Both factors had high internal consistency. CFA within subsamples of English, Mandarin, and Malay languages indicated similar findings. MGCFA results indicate that measurement invariance held across the different languages, ethnicities, and those with and without chronic illnesses.

Conclusion

The present study identified a two-factor (physical and mental health) structure within the general population and amongst the three different languages and demonstrated the measurement invariance of SF-12v2 across different subgroups. Findings indicate that algorithm-derived PCS and MCS should be interpreted with caution as they may result in inaccurate conclusions regarding the relationships between HRQoL and its correlates. Future studies using the SF-12v2 within the general population of Singapore should consider utilizing the factor structure put forth in the present study to obtain more appropriate estimates of HRQoL.

Introduction

In Australia, health-related quality of life (HRQoL) instruments have been adopted in national population surveys to inform policy decisions that affect the health of Aboriginal and Torres Strait Islanders. However, Western-developed HRQoL instruments should not be assumed to capture Indigenous conceptualization of health and well-being. In our study, following recommendations for cultural adaptation, an Indigenous Reference Group indicated the EQ-5D-5L as a potentially valid instrument to measure aspects of HRQoL and endorsed further psychometric evaluation. Thus, this study aimed to investigate the construct validity and reliability of the EQ-5D-5L in an Aboriginal Australian population.

Methods

The EQ-5D-5L was applied in a sample of 1012 Aboriginal adults. Dimensionality was evaluated using Exploratory Graph Analysis. The Partial Credit Model was employed to evaluate item performance and adequacy of response categories. Area under the receiver operating characteristic curve (AUROC) was used to investigate discriminant validity regarding chronic pain, general health and experiences of discrimination.

Results

The EQ-5D-5L comprised two dimensions, Physiological and Psychological, and reliability was adequate. Performance at an item level was excellent and the EQ-5D-5L individual items displayed good discriminant validity.

Conclusions

The EQ-5D-5L is a suitable instrument to measure five specific aspects (Mobility, Self-Care, Usual activities, Pain/Discomfort, Anxiety/Depression) of Aboriginal and Torres Strait Islander HRQoL. A future research agenda comprises the investigation of other domains of Aboriginal and Torres Strait Islander HRQoL and potential expansions to the instrument.
Cost-effectiveness of a reactive oral cholera immunization campaign using Shanchol™ in Malawi

Published: March 2021

Background

Oral cholera vaccines (OCV) have been recommended as additional measures for the prevention of cholera. However, little is known about the cost-effectiveness of OCV use in sub-Saharan Africa, particularly in reactive outbreak contexts. This study aimed to investigate the cost-effectiveness of the use of OCV Shanchol in response to a cholera outbreak in the Lake Chilwa area, Malawi.

Methods

The Excel-based Vaccine Introduction Cost-Effectiveness model was used to assess the cost-effectiveness ratios with and without indirect protection. Model input parameters were obtained from cost evaluations and epidemiological studies conducted in Malawi and published literature. One-way sensitivity and threshold analyses of cost-effectiveness ratios were performed.

Results

Compared with the reference scenario i.e. treatment of cholera cases, the immunization campaign would have prevented 636 and 1 020 cases of cholera without and with indirect protection, respectively. The cost-effectiveness ratios were US$19 212 per death, US$500 per case, and US$738 per DALY averted without indirect protection. They were US$10 165 per death, US$264 per case, and US$391 per DALY averted with indirect protection. The net cost per DALY averted was sensitive to four input parameters, including case fatality rate, duration of immunity (vaccine’s protective duration), discount rate and cholera incidence.

Conclusion

Relative to the Malawi gross domestic product per capita, the reactive OCV campaign represented a cost-effective intervention, particularly when considering indirect vaccine effects. Results will need to be assessed in other settings, e.g., during campaigns implemented directly by the Ministry of Health rather than by international partners.

Background

Australian podiatrists and podiatric surgeons who have successfully completed the requirements for endorsement for scheduled medicines, as directed by the Podiatry Board of Australia, are eligible to prescribe a limited amount of schedule 2, 3, 4 or 8 medications. Registration to become endorsed for scheduled medicines has been available to podiatrists for over 10 years, yet the uptake of training has remained low (approximately 2% of registered podiatrists/podiatry surgeons). This study aimed to explore barriers to and facilitators of engagement with endorsement for scheduled medicines by podiatrists.

Methods

Qualitative descriptive methodology informed this research. A purposive maximum variation sampling strategy was used to recruit 13 registered podiatrists and a podiatric surgeon who were either endorsed for scheduled medicines, in training or not endorsed. Semi‐structured interviews were employed to collate the data which were analysed using thematic analysis.

Results

Three overarching super‐ordinate themes were identified which encompassed both barriers and facilitators: (1) competence and autonomy, (2) social and workplace influences, and (3) extrinsic motivators. Within these, several prominent sub‐themes emerged of importance to the participants including workplace and social networks role in modelling behaviours, identifying mentors, and access to supervised training opportunities. Stage of life and career often influenced engagement. Additionally, a lack of financial incentive, cost and time involved in training, and lack of knowledge of training requirements were influential barriers. Rural podiatrists encountered a considerable number of barriers in most of the identified areas.

Conclusion

A multitude of barriers and facilitators exist for podiatrists as part of the endorsement for scheduled medicines. The findings suggest that a lack of engagement with endorsement for scheduled medicines training may be assisted by a more structured training process and increasing the number of podiatrists who are endorsed to increase the numbers of role models, mentors, and supervision opportunities. Recommendations are provided for approaches as means of achieving, and sustaining, these outcomes.
