Health Sciences students’ experience of COVID-19 case management and contact tracing in Cape Town, South Africa
Authors: Zweigenthal Virginia , Perez Gonda , Wolmarans Karen , Olckers Lorna
Published: April 2023

Background

COVID-19 has challenged health and higher education systems globally. Managing the epidemic in Cape Town, South Africa (SA), required partnerships with universities and setting up of de novo systems for mass case and contact tracing (C&CT). Health sciences, predominantly medical students, as well as social work and psychology students formed the core of this telephone-based work over the 18 months when SARS-CoV-2 caused severe disease.

Methods

This qualitative study aimed to elicit students’ motivations for becoming involved in C&CT, their experiences, and recommendations for C&CT and curricula. After Cape Town’s first COVID-19 wave, six on-line focus groups comprising 23 students were conducted, and a further four were conducted with 13 students after the second wave. As the researchers were predominantly educators previously involved in undergraduate health sciences education, the study’s purpose was to reflect on students’ experiences to make educational and health system recommendations.

Results

Students were largely motivated to mitigate the impact of the epidemic on society and support people affected by COVID-19, as well as hone their professional skills. While these motivations were realised, students also needed to learn new skills – to autonomously work remotely, using novel communication strategies to engage those affected and use virtual groups to connect with colleagues. They managed responsibilities within the healthcare systems that did not always work smoothly, distressed cases who were financially insecure, difficult employers, and language barriers. They were prepared through training, and supported by virtual, yet effective teamwork and debriefing opportunities. Although the work was sometimes physically and emotionally exhausting, students found the work personally meaningful. They embraced public health’s role to protect population and individuals’ health.

Conclusion

New teaching and learning practices adopted due to Covid-19 lockdowns enabled this digital C&CT project. It facilitated students to become confident, work autonomously and navigate challenges they will encounter as young professionals. The programme demonstrated that novel opportunities for rich student learning, such as in telehealth, can be embedded into public health and clinical functions of health services in contexts such as in SA, deepening partnerships between the health services and universities, to mutual benefit.

Authors: Rodrigues da Silva Noll Gonçalves Jéssica , Noll Gonçalves Rodrigo , da Rosa Saulo Vinicius , Schaia Rocha Orsi Juliana , Santos de Paula Karoline Maria , Moysés Samuel Jorge , Werneck Renata Iani
Published: April 2023

Background

Rapid demographic, epidemiological, technological, cultural/behavioural, and educational transitions, as they become more complex, demand new integrated and complementary professional skills and abilities. Interprofessional Education (IPE) is a promising alternative to deal with these changes, especially in courses in the health area. This systematic review was to explore the potentialities and limitations of IPE, from the perspective of undergraduate students, through a thematic synthesis of qualitative studies.

Methods

A thematic synthesis of qualitative studies was conducted. The question elaborated for this review was: “What is the impact of interprofessional education on the teaching and learning of students in the health area inserted in Higher Education Institutions?”. The search strategy was performed in the electronic databases PubMed, Latin American and Caribbean Literature in Health Sciences (LILACS), Cochrane Library, and Scientific Electronic Library Online (SciELO). In addition, searches were carried out in grey literature on the ERIC platforms, ProQuest Disserts and Theses, and Academic Google. The assessment of the quality of the studies was carried out using the Critical Appraisal Skills Programme tool. Data were summarized through thematic synthesis. From the databases, 8,793 studies were identified. After standardized filters procedures, critical summaries, and assessment of relevance to the eligibility criteria, 14 articles were included.

Results

The synthesis of the studies revealed the potential of this teaching approach, arranged in three analytical themes: learning from each other and about them; the value of education and interprofessional practice; patient-centred health care. On the other hand, some limitations were also identified, such as barriers related to EIP; the difficulties related to teaching methodologies.

Conclusion

Overcoming the identified limitations can enhance the results of the IPE, in view of its impact on the education of students and on the health care of the population.
Interactive Patient Safety and Quality Improvement capstone during transition-to-residency program: virtual and in-person focused workshop for EPA 13
Authors: Chen Catherine , Coppola Kristen M. , Weber Paul , Parikh Payal
Published: April 2023

Identifying systems failures and contributing to a safety culture is the Association of American Colleges (AAMC’s) thirteenth Entrustable Professional Activity (EPA). While most curricula teach Patient Safety (PS) and Quality Improvement (QI) principles, student participation in live QI/PS activities remains limited. This workshop enabled late Clerkship phase students to apply these Health Systems Science (HSS) principles to real adverse patient event cases through team-based simulation.

This 3-h capstone included both a didactic review of QI, PS, and TeamSTEPPS® tools and an experiential component where student-led interactive small group discussions were augmented by resident and faculty preceptors. Collaboratively, students composed an adverse patient event report, conducted a Root Cause Analysis (RCA) during role-play, and proposed error prevention ideas after identifying systems problems. In April 2020, the in-person workshop became fully virtual due to the COVID-19 pandemic.

A statistically significant increase in ability to identify Serious Safety Events, Escalation Chain of Command, and define a Plan-Do-Study-Act (PDSA) cycle was observed. Comfort with RCA increased from 48 to 87% and comfort with TeamSTEPPS® principles increased from 68% to 85.5%

This novel capstone provided students with the tools to synthesize HSS concepts through problem-solving processes and recognize EPA 13’s importance. Their increased capability to identify appropriate chain of command, escalate concerns, and recognize serious adverse patient events also has training and practice readiness implications.
Sexual harassment as experienced by nurses from selected healthcare facilities in Ghana
Authors: Mohammed Aliu , Ansah Edward Wilson , Apaak Daniel
Published: April 2023

Background

Workplace Sexual Harassment (WSH) remains a major occupational health hazard to many nurses globally. Despite the negative impact of WSH on health and safety of nurses, there are limited studies exploring sexual harassment experiences of nurses in the line of duty in Low- and middle-income countries (LMICs) including Ghana.

Aim

This study aimed at exploring the lived sexual harassment experiences among nurses working in healthcare facilities in the Central Region of Ghana.

Method

This study used a qualitative interpretive phenomenological approach (IPA). Data from 24 participants, 13 participants’ written descriptive narratives of sexual harassment experiences (via online) and 11 telephone interviews were analysed concurrently using the IPA.

Results

Participants experienced verbal, non-verbal and physical forms of sexual harassment, often perpetrated by physicians, colleague workers, and patients. Most victims reacted passively to the acts sexual harassment and cases are often not reported despite the negative impact on victims’ health. While some participants dealt with sexual harassment by accepting the behaviour as an inevitable part of their job, others either quit or intend to quit the job to avoid the harassers. Most participants are unaware of any workplace measure such as policy that addresses sexual harassment in the health sector in Ghana.

Conclusion

This study highlights the problems of sexual harassment against nurses in the healthcare sector in Ghana, and calls for urgent development of measures such as a sexual harassment policy to prevent occurrence and promote effective resolution of sexual harassment within the healthcare sector in the country. Sexual harassment against nurses could be hampering quality healthcare delivery in the region.
The moderating effect of cultural competence educational needs on the relationship between transcultural self-efficacy and cultural competence in Korean public health nurses
Authors: Han Young-Ran , Jeong Yeo-Won
Published: April 2023

Background

In an increasingly multicultural society, cultural competence and transcultural self-efficacy of public health nurses is important for providing culturally congruent care for client from diverse cultural background. To improv this, it is needed tailored and effective educational program based on the cultural competence educational needs. This study investigated the moderating effect of cultural competence educational needs on the relationship between transcultural self-efficacy and cultural competence.

Methods

This cross-sectional study recruited 217 public health nurses in Korea using convenience sampling from August 2018 to January 2019. A direct questionnaire was used to collect data. Study variables were analyzed using descriptive statistics, correlation, and the Hayes PROCESS macro (Model 1) moderation model.

Results

The mean scores for transcultural self-efficacy, cultural competence educational needs, and cultural competence were 62.33 ± 11.08, 58.19 ± 15.08, and 97.96 ± 17.09, respectively. Transcultural self-efficacy and cultural competence educational needs were positively associated with cultural competence. In the tested model, cultural competence educational needs had a conditional moderating effect on the relationship between transcultural self-efficacy and cultural competence. The positive association between transcultural self-efficacy and cultural competence was significant at low, medium, and high levels of cultural competence educational needs and stronger for those with high needs.

Conclusions

Cultural competence educational needs may be an important determinant of cultural competence among public health nurses. To effectively increase cultural competence, transcultural self-efficacy should be increased by education programs tailored by cultural competence educational needs.
Gender similarities and differences in the perception of caring among nurses during the COVID-19 pandemic: a mixed-methods study
Authors: Tong Lai Kun , Zhu Ming Xia , Wang Si Chen , Cheong Pak Leng , Van Iat Kio
Published: April 2023

Background

Caring is the essence and core of nursing. Current studies on the effect of gender on nurses’ perception of caring have been inconsistent. Most of these studies were quantitative and conducted before the COVID-19 pandemic. The study aimed to explore the gender similarities and differences in nurses’ perception of caring during the COVID-19 pandemic.

Methods

In 2020, a cross-sectional mixed-method study was conducted in 11 cities in China using structured online questionnaire (n = 8030) and face-to-face individual interview (n = 42). Data collection tools included the Caring Dimensions Inventory and semi-structured interview.

Results

In stepwise multivariable linear regression analysis, female nurses scored 1.93 points higher on caring than male nurses, after completely controlling for the other factors. The interview results showed that both male and female nurses agreed that caring was to deal with three kinds of relationships, namely nurses and people, nurses and themselves, nurses and society. There were gender differences in the connotation of caring between nurses and themselves, but not in the connotations of caring between other relationships. The ranking of the importance of caring connotations among these relationships showed no gender difference except between nurses and themselves.

Conclusion

The quantitative findings suggest that gender influences nurses’ perception of caring. The qualitative findings demonstrate that nurses regard themselves as both recipients and implementers of caring. The qualitative results indicate nurses of different genders have similarities and differences in their perception of caring, and the biggest difference lies in the relationship between nurses and themselves.
The mediating effect of psychological empowerment on the relationship between work environment and clinical decision-making among midwives: a multicentre cross-sectional study
Authors: Zeng Jing , Guo Sheng-Bin , Zheng Qing-Xiang , Liu Xiu-Wu , Lin Hui-Ming , Hu An-Fen , Yang Yan , Wei Bi-Rong
Published: April 2023

Background

Clinical decision-making is considered an essential behaviour in clinical practice. However, no research has been done to examine the associations among midwives’ clinical decision-making, work environment and psychological empowerment. Thus, this study aimed to determine the influence of work environment on midwives’ clinical decision-making and confirm the mediating role of psychological empowerment.

Method

This study was designed as a multicentre cross-sectional study, and included 602 registered midwives from 25 public hospitals in China. A sociodemographic questionnaire, Work Environment Scale, Psychological Empowerment Scale and Clinical decision-making Scale were applied. A structural equation model was conducted to estimate the hypothesis model of the clinical decision-making among midwives and explore the potential mediating mechanism of midwives’ clinical decision-making. This model was employed maximum likelihood estimation method and bootstrapping to examine the statistical significance.

Results

The mean score of clinical decision-making among midwives was 143.03 ± 14.22, at an intermediate level. The data of this hypothesis model fitted well, and the results showed that work environment positively affected psychological empowerment, which in turn positively affected clinical decision-making; psychological empowerment partly mediated the relationship between work environment and clinical decision-making among midwives.

Conclusions

Midwives’ clinical decision-making could be promoted directly or indirectly by providing a healthy work environment and improving psychological empowerment. It is essential for hospital managers to pay attention to the assessment of the midwives’ work environment and actively improve it, such as establishing a supportive, fair and just workplace, and maintaining effective communication with midwives. Furthermore, managers can also promote midwives’ clinical decision-making behaviour by enhancing their psychological empowerment via enhancing job autonomy.
Counseling regarding the care of people with dementia with a focus on §7a SGB XI in Germany: a "gray-shaded" scoping review
Authors: Rommerskirch-Manietta Mike , Manietta Christina , Purwins Daniel , Roes Martina
Published: April 2023

Background

Care counseling is an important psychosocial intervention for people with care needs and their relatives and can contribute to maintaining and/or improving a patient’s quality of life and reducing the burden of caregivers. This is especially the case for people with dementia and their relatives, in which the methods of care counseling need to be different than those for individuals with non-dementia related care needs. Furthermore, the counseling content needs to be adjusted to the specific form and stage of dementia. In Germany, every person who receives support per the German Social Law Book XI (SBG XI) can take advantage of care counseling according to §7a SGB XI. To date, there is no systematic overview of counseling services for people with dementia and their relatives related to this specific provision in Germany.

Methods

We conducted a gray-shaded scoping review with a focus on the evaluation of care counseling according to §7a SGB XI for people with dementia and their relatives. For this purpose, we applied five search strategies. We researched (1) national electronic databases, (2) Google, (3) targeted websites, (4) experts, and (5) academic electronic databases. Additionally, for the included gray literature, we conducted backward citation tracking via reference lists and forward citation tracking via Google Scholar for scientific articles. Screening of the identified potentially relevant records was performed independently by two reviewers.

Results

We identified 985 records and included 6 studies in our review. We divided the identified studies into three themes: understanding conceptual dimensions, digitalization of counseling, and understanding the perspective of those being counseled. No studies investigated the perspective and experience of people with dementia and their relatives regarding the counseling service according to §7a SGB XI.

Conclusions

Our results show that further research is needed, especially regarding the experience of people with dementia and their relatives who participated in counseling according to §7a SGB XI. It seems essential to understand the perspective of people with dementia and their relatives to improve and tailor counseling services in Germany.

Registration

The review protocol was prospectively published (BMJ Open 12:e059771, 2022).
Adverse birth outcomes and early-life infections after in utero exposure to corticosteroids for inflammatory bowel disease: a Danish nationwide cohort study
Authors: Jølving Line Riis , Nielsen Jan , Andersen Mette Louise , Friedman Sonia , Nørgård Bente Mertz
Published: April 2023

Background

Systemic corticosteroids are often used to treat inflammatory bowel disease (IBD) flares during pregnancy as maintenance of disease remission is crucial to optimize pregnancy outcomes. However, there is little data regarding the effect of in utero exposure to corticosteroids on the risk of adverse birth outcomes and early-life infections in the offspring.

Methods

We used the Danish national registries to establish a nationwide cohort of all singleton live births in women with IBD from 1995 to 2015. Outcomes in children exposed in utero to corticosteroids were compared to those who were not exposed. In logistic and Cox proportional hazard regression models, we adjusted the outcomes (major congenital malformation, preterm birth, small for gestational age, low 5-min Apgar score, and infections) for confounders such as body mass index, smoking, comorbidity, and additional medical IBD treatment.

Results

After in utero exposure to corticosteroids at any time between 30 days prior to conception through the first trimester (n = 707), the adjusted hazard ratio of major congenital malformation was 1.28 (95% CI: 0.82–2.00) compared to children born to women with IBD, but not exposed to corticosteroids in utero (n = 9371). After in utero exposure to corticosteroids at any time during pregnancy (n = 1336), the adjusted odds ratios for preterm birth, small for gestational age, and low 5-min Apgar score were 2.45 (95% CI: 1.91–3.13), 1.21 (95% CI: 0.76–1.90), and 0.91 (95% CI: 0.33–2.52), respectively. Finally, the adjusted hazard ratio of overall infections in the first year of life was 1.14 (95% CI: 0.94–1.39).

Conclusions

This nationwide cohort study suggests that children of women with IBD exposed to corticosteroids in utero had an almost 2.5-fold increased risk of preterm birth. Use of corticosteroids is closely related to disease activity and we cannot adjust for the independent role of disease activity. It is however reassuring that the other examined birth and early-life outcomes were not statistically significantly increased.
Association of stress hyperglycemia with clinical outcomes in patients with ST-elevation myocardial infarction undergoing percutaneous coronary intervention: a cohort study
Authors: Wei Qu-Cheng , Chen Yu-wen , Gao Qi-Yue , Ren Kai-Da , Liu Ya-Bin , He Fan , Shi Jia-Tong , Jiang Jun
Published: April 2023

Background

In recent years, several studies have demonstrated that stress hyperglycemia is significantly associated with poor prognosis in patients diagnosed with acute coronary syndrome (ACS). In the present study, we aimed to investigate the potential associations between various markers of stress hyperglycemia, such as admission blood glucose (ABG), fasting blood sugar (FBS), and stress hyperglycemia ratio (SHR) with different definitions, and the occurrence of adverse cardiovascular events in patients diagnosed with ST-elevation myocardial infarction (STEMI) who have undergone percutaneous coronary intervention (PCI).

Methods

Our study enrolled a total of 1099 patients diagnosed with STEMI who underwent PCI from 2016 to 2021. The primary outcomes of this study were in-hospital death and all-cause mortality.

Results

Stress hyperglycemia was associated with a higher incidence of in-hospital death (ABG OR: 1.27 95% CI 1.19–1.36; FBS OR: 1.25 95% CI 1.16–1.35; SHR1 OR: 1.61 95% CI 1.21–2.14; SHR2 OR: 1.57, 95%CI 1.22–2.01; SHR3 OR: 1.59, 95%CI 1.24–2.05) and all-cause mortality (ABG HR: 1.10, 95% CI 1.07–1.14; FBS HR: 1.12, 95 CI 1.07–1.17; SHR1 HR: 1.19 95% CI 1.03–1.39; SHR2 HR: 1.28, 95%CI 1.14–1.44; SHR3 HR: 1.29, 95%CI 1.14–1.45) after adjusting for ischemic time, age, gender, BMI, hypertension, hyperlipidemia, diabetes mellitus (DM), current smoking history, chronic kidney disease (CKD), previous history of coronary artery disease (CAD), atrial fibrillation (AF), heart failure (HF), stroke, cancer, culprit vessel, multi-vessel disease. These associations exhibited a non-linear, J-shaped pattern, wherein the risk significantly increased when the ABG and FBS levels exceeded 5mmol/L. Moreover, the inflection point for SHR was estimated to be 1.2.

Conclusions

Stress hyperglycemia was significantly associated with an increased risk of in-hospital death and all-cause mortality in STEMI patients treated with PCI. Stress hyperglycemia should be considered a high-risk prognostic marker in all STEMI patients, regardless of with or without diabetes.

Published: April 2023

Background

This study aimed to isolate a novel thermotolerant bacterium that is capable of synthesizing polyhydroxyalkanoate from glycerol under high temperature conditions.

Results

A newly thermotolerant polyhydroxyalkanoate (PHA) producing bacterium, Cupriavidus sp. strain CB15, was isolated from corncob compost. The potential ability to synthesize PHA was confirmed by detection of PHA synthase (phaC) gene in the genome. This strain could produce poly(3-hydroxybutyrate) [P(3HB)] with 0.95 g/L (PHA content 75.3 wt% of dry cell weight 1.24 g/L) using glycerol as a carbon source. The concentration of PHA was enhanced and optimized based on one-factor-at-a-time (OFAT) experiments and response surface methodology (RSM). The optimum conditions for growth and PHA biosynthesis were 10 g/L glycerol, 0.78 g/L NH4Cl, shaking speed at 175 rpm, temperature at 45 °C, and cultivation time at 72 h. Under the optimized conditions, PHA production was enhanced to 2.09 g/L (PHA content of 74.4 wt% and dry cell weight of 2.81 g/L), which is 2.12-fold compared with non-optimized conditions. Nuclear magnetic resonance (NMR) analysis confirmed that the extracted PHA was a homopolyester of 3-hydyoxybutyrate.

Conclusion

Cupriavidus sp. strain CB15 exhibited potential for cost-effective production of PHA from glycerol.
Identification of novel cell-free RNAs in maternal plasma as preterm biomarkers in combination with placental RNA profiles
Authors: Jin Heyue , Zhang Yimin , Fan Zhigang , Wang Xianyan , Rui Chen , Xing Shaozhen , Dong Hongmei , Wang Qunan , Tao Fangbiao , Zhu Yumin
Published: April 2023

Background

Preterm birth (PTB) is the main driver of newborn deaths. The identification of pregnancies at risk of PTB remains challenging, as the incomplete understanding of molecular mechanisms associated with PTB. Although several transcriptome studies have been done on the placenta and plasma from PTB women, a comprehensive description of the RNA profiles from plasma and placenta associated with PTB remains lacking.

Methods

Candidate markers with consistent trends in the placenta and plasma were identified by implementing differential expression analysis using placental tissue and maternal plasma RNA-seq datasets, and then validated by RT-qPCR in an independent cohort. In combination with bioinformatics analysis tools, we set up two protein–protein interaction networks of the significant PTB-related modules. The support vector machine (SVM) model was used to verify the prediction potential of cell free RNAs (cfRNAs) in plasma for PTB and late PTB.

Results

We identified 15 genes with consistent regulatory trends in placenta and plasma of PTB while the full term birth (FTB) acts as a control. Subsequently, we verified seven cfRNAs in an independent cohort by RT-qPCR in maternal plasma. The cfRNA ARHGEF28 showed consistence in the experimental validation and performed excellently in prediction of PTB in the model. The AUC achieved 0.990 for whole PTB and 0.986 for late PTB.

Conclusions

In a comparison of PTB versus FTB, the combined investigation of placental and plasma RNA profiles has shown a further understanding of the mechanism of PTB. Then, the cfRNA identified has the capacity of predicting whole PTB and late PTB.
The effect of etanercept therapy on adrenal steroid metabolism in juvenile idiopathic arthritis: a steroid metabolomics approach
Authors: Aviel Yonatan Butbul , Keinan Ariel , Hartmann Michaela F. , Wudy Stefan A. , Tiosano Dov
Published: April 2023

Objective

To evaluate the impact of anti-tumor necrosis factor-alpha (TNFα: etanercept [Etanercept ®]) therapy on adrenal activity in juvenile idiopathic arthritis (JIA) .

Method

Eleven JIA patients aged 12 ± 6.2 years with a disease duration of 6.3 ± 5.2 years were enrolled. They were treated once weekly with etanercept (0.8 mg/kg) for 3 ± 2.8 years. Urine samples for gas chromatography-mass spectrometry steroid hormone analysis were collected before, and 1 and 3 days after etanercept injection and compared to age- and sex-matched healthy controls.

Results

The levels of 21 of the 31 metabolites were low before etanercept treatment. Those 21 metabolites included 4 C19 steroids (androgens), 5 C C21 steroid hormone intermediates, 10 cortisol metabolites, and 2 corticosterone metabolites. One day after treatment, only 5 of the 21 metabolite levels remained low. They included 2 C19 metabolites, 2 C21 steroid metabolites and 1 cortisol metabolite β –Cortol (β-Cl). Three days after treatment, the only metabolites levels that continued to be low were 2 C19 metabolite, 2 C21 steroid hormone intermediates and 1 cortisol metabolite α-Cortol (a-Cl), while the remaining 15 metabolites had already normalized after 1 day. Dehydroepiandrosterone-sulfate and 17-hydroxypregnenolone metabolite levels were the last ones to recover. Urinary metabolite ratios reflecting cytochrome P450 CYP21A2 (21-hydroxylase) and 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) enzymatic activitieswere lower in JIA patients than in controls, although significant was not reached.

Conclusion

Almost all of the pre-etanercept treatment cortisol urinary metabolite levels were significantly lower than normal, and almost all rose to normal values by 1 day after treatment. The therapeutic effect of anti-TNFα treatment in JIA may be related to its effect on the restoration of adrenal function and cortisol levels.
Perspectives on ankle-foot technology for improving gait performance of children with Cerebral Palsy in daily-life: requirements, needs and wishes
Authors: Bayón Cristina , Hoorn Marleen van , Barrientos Antonio , Rocon Eduardo , Trost Joyce P. , Asseldonk Edwin H. F. van
Published: April 2023

Background

Ankle-foot orthoses (AFOs) are extensively used as a primary management method to assist ambulation of children with Cerebral Palsy (CP). However, there are certain barriers that hinder their prescription as well as their use as a mobility device in all kinds of daily-life activities. This exploratory research attempts to further understand the existing limitations of current AFOs to promote a better personalization of new design solutions.

Methods

Stakeholders’ (professionals in CP and end-users with CP) perspectives on AFO technology were collected by two online surveys. Respondents evaluated the limitations of current assistive solutions and assessment methods, provided their expectations for a new AFO design, and analyzed the importance of different design features and metrics to enrich the gait performance of these patients in daily-life. Quantitative responses were rated and compared with respect to their perceived importance. Qualitative responses were classified into themes by using content analysis.

Results

130 survey responses from ten countries were analyzed, 94 from professionals and 36 from end-users with CP. The most highly rated design features by both stakeholder groups were the comfort and the ease of putting on and taking off the assistive device. In general, professionals preferred new features to enrich the independence of the patient by improving gait at functional levels. End-users also considered their social acceptance and participation. Health care professionals reported a lack of confidence concerning decision-making about AFO prescription. To some degree, this may be due to the reported inconsistent understanding of the type of assistance required for each pathological gait. Thus, they indicated that more information about patients’ day-to-day walking performance would be beneficial to assess patients’ capabilities.

Conclusion

This study emphasizes the importance of developing new approaches to assess and treat CP gait in daily-life situations. The stakeholders’ needs and criteria reported here may serve as insights for the design of future assistive devices and for the follow-up monitoring of these patients.
Which resistance training is safest to practice? A systematic review
Authors: Serafim Thiago Teixeira , de Oliveira Eliton Stanley , Maffulli Nicola , Migliorini Filippo , Okubo Rodrigo
Published: April 2023

Background

The combination of resistance training (RT) and aerobic training is believed to achieve the best effects. Several different aerobic training methods have emerged in combination with or as a substitute for traditional RT. This study wished to verify which RT is safest in terms of injury prevalence and incidence. Also, it ascertained the characteristics of the injured subjects, the level of severity of the injuries and what definitions of injuries the available studies use.

Methods

This systematic review followed the PRISMA recommendations and was registered in PROSPERO with the number CRD42021257010. The searches were performed in the PubMed, Cochrane and Web of Science, electronic databases using the Medical Subject Headings terms "Resistance training" or "Strength training" or "Crossfit" or “Weightlifting” or “Powerlifting” combined (AND) with "Injury" or "Injuries" or "Sprain" AND “Incidence” or “Prevalence” AND “Epidemiology” or “Epidemiological” in the title or abstract. The last search was performed on March 2023. To be included in the review, the studies had to be available as full text, be clinical trials focusing on epidemiological injuries of resistance training. There was no time limit for the selection of articles. To assess the quality of the studies, the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) was used.

Results

The initial literature search resulted in 4982 studies. After reading the titles, abstracts and full text, 28 articles were selected for data extraction. Seventeen investigated the injuries in HIFT/CrossFit, three in powerlifting, three in strength training, three in weightlifting and one in strongman. In addition, one study examined the HIFT/CrossFit and weightlifting. The incidence of injuries presented in the studies ranged from 0.21/1000 h to 18.9/1000 h and the prevalence of injuries was 10% to 82%. In the quality assessment for STROBE, five studies were classified at level A, 21 at level B and two at level C.

Conclusion

This systematic review showed that traditional strength training is the safest RT method, and strongman is the least safe regarding injuries. Few studies have been rated highly according to STROBE. Furthermore, few studies have been published on some RT methods. These two factors make it difficult to generalize the results.
N6-methyladenosine regulator-mediated methylation modification patterns and immune infiltration characterization in Polycystic Ovary Syndrome (PCOS)
Authors: Zhou Sihan , Hua Rui , Quan Song
Published: April 2023

Background

Polycystic ovary syndrome (PCOS) is a multisystem-related disease whose pathophysiology is still unclear. Several regulators of N6-methyladenosine (m6A) modification were confirmed to play a regulatory role in PCOS. Nonetheless, the roles of m6A regulators in PCOS are not fully demonstrated.

Materials and methods

Four mRNA expression profiling microarrays were obtained from the Gene Expression Omnibus (GEO) database. Differentially expressed m6A regulators between PCOS and normal patients were identified by R software. A random forest modal and nomogram were developed to assess the relationship between m6A regulators and the occurrence risk of PCOS. A consensus clustering method was utilized to distinctly divide PCOS patients into two m6A subtypes (m6A cluster A/B). The patterns of differential expression and immune infiltration were explored between the two m6A clusters.

Results

In this study, 22 significant m6A regulators were identified between healthy controls and PCOS patients. The random forest model determined three optimal m6A regulators which are related to the occurrence risk of PCOS, including YTHDF1, RBM15 and METTL14. A nomogram was established based on these genes, and its predictive reliability was validated by decision curve analysis. The consensus clustering algorithm distinctly divided PCOS cases into two m6A subtypes. The ssGSEA algorithm found that the immune infiltration was markedly enriched in m6A cluster B than in cluster A. The m6A-pattern related differentially expressed genes (DEGs) of the two m6A subtypes were demonstrated by differential expression analysis. We found that they were enriched in immune-related genes and various infection pathways. Based on the m6A-pattern related DEGs, the PCOS patients were classified into two m6A-pattern related genomic subtypes (gene clusters A and B).

Conclusions

The present study provided evidence concerning the different modification patterns of m6A regulators in PCOS compared with normal patients. This study will help clarify the overall impact of m6A modification patterns and related immune infiltration on PCOS.
How to combine the use of intraoperative magnetic resonance imaging (MRI) and awake craniotomy for microsurgical resection of hemorrhagic cavernous malformation in eloquent area: a case report
Authors: Tuleasca Constantin , Peciu-Florianu Iulia , Strachowski Ondine , Derre Benoit , Vannod-Michel Quentin , Reyns Nicolas
Published: April 2023

Background

Cavernous malformations are clusters of abnormal and hyalinized capillaries without interfering brain tissue. Here, we present a cavernous malformation operated under awake conditions, due to location, in an eloquent area and using intraoperative magnetic resonance imaging due to patient’s movement upon the awake phase.

Case presentation

We present the pre-, per-, and postoperative course of an inferior parietal cavernous malformation, located in eloquent area, in a 27-year-old right-handed Caucasian male, presenting with intralesional hemorrhage and epilepsy. Preoperative diffusion tensor imaging has shown the cavernous malformation at the interface between the arcuate fasciculus and the inferior fronto-occipital fasciculus. We describe the microsurgical approach, combining preoperative diffusion tensor imaging, neuronavigation, awake microsurgical resection, and intraoperative magnetic resonance imaging.

Conclusion

Complete microsurgical en bloc resection has been performed and is feasible even in eloquent locations. Intraoperative magnetic resonance imaging was considered an important adjunct, particularly used in this case as the patient moved during the “awake" phase of the surgery and thus neuronavigation was not accurate anymore. Postoperative course was marked by a unique, generalized seizure without any adverse event. Immediate and 3 months postoperative magnetic resonance imaging confirmed the absence of any residue. Pre- and postoperative neuropsychological exams were unremarkable.

Background

Miliary tuberculosis is a life-threatening disease caused by the hematogenous spread of Mycobacterium tuberculosis. It is uncommon in pregnancy. Mortality rates for patients with miliary tuberculosis who require mechanical ventilation are high (60–70%).

Case presentation

We reported a rare and challenging case, a 35-year-old Asian woman with 34 weeks of pregnancy, and miliary tuberculosis with acute respiratory distress syndrome and septic shock. The patient presented with severe acute respiratory distress syndrome, necessitating mechanical ventilation, vasopressor, and pregnancy termination with caesarean section. The patient underwent blood purification with continuous veno-venous hemofiltration using an oXiris filter for 24 hours. After continuous veno-venous hemofiltration, the patient’s condition was greatly improved, and the patient was successfully extubated and was able to breathe spontaneously without vasopressor on the third day. High levels of interleukin-6, interleukin-10, procalcitonin, C-reactive protein, interferon-γ, and tumor necrosis factor-α were found postoperatively.

Conclusion

The bacterial infection of tuberculosis, acute respiratory distress syndrome, and the stress response from the caesarean section contributed to the high levels of cytokines, which correlated with the patient’s severe inflammatory condition. The cytokine levels were greatly reduced after the blood purification procedure and this might be associated with the patient’s clinical improvement. Extracorporeal blood purification could help to disrupt the vicious cycle of inflammation.
Tuberculosis infection prevention and control in rural Papua New Guinea: an evaluation using the infection prevention and control assessment framework
Authors: Marme Gigil , Kuzma Jerzy , Zimmerman Peta-Anne , Harris Neil , Rutherford Shannon
Published: April 2023

Background

Papua New Guinea (PNG) is one of the 14 countries categorised as having a triple burden of tuberculosis (TB), multidrug-resistant TB (MDR TB), and TB-human immunodeficiency virus (HIV) co-infections. TB infection prevention and control (TB-IPC) guidelines were introduced in 2011 by the National Health Department of PNG. This study assesses the implementation of this policy in a sample of district hospitals in two regions of PNG.

Methods

The implementation of TB-IPC policy was assessed using a survey method based on the World Health Organization (WHO) IPC assessment framework (IPCAF) to implement the WHO’s IPC core components. The study included facility assessment at ten district hospitals and validation observations of TB-IPC practices.

Results

Overall, implementation of IPC and TB-IPC guidelines was inadequate in participating facilities. Though 80% of facilities had an IPC program, many needed more clearly defined IPC objectives, budget allocation, and yearly work plans. In addition, they did not include senior facility managers in the IPC committee. 80% (n = 8 of 10) of hospitals had no IPC training and education; 90% had no IPC committee to support the IPC team; 70% had no surveillance protocols to monitor infections, and only 20% used multimodal strategies for IPC activities. Similarly, 70% of facilities had a TB-IPC program without a proper budget and did not include facility managers in the TB-IPC team; 80% indicated that patient flow poses a risk of TB transmission; 70% had poor ventilation systems; 90% had inadequate isolation rooms; and though 80% have personal protective equipment available, frequent shortages were reported.

Conclusions

The WHO-recommended TB-IPC policy is not effectively implemented in most of the participating district hospitals. Improvements in implementing and disseminating TB-IPC guidelines, monitoring TB-IPC practices, and systematic healthcare worker training are essential to improve TB-IPC guidelines’ operationalisation in health settings to reduce TB prevalence in PNG.
Food addiction and its relationship with other eating behaviours among Spanish university students

Published: April 2023

Background

Food addiction (FA) is characterised by symptoms such as loss of control over food consumption, inability to reduce consumption despite the desire to do so, and continued consumption despite negative consequences. The modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) is a widely used instrument to assess FA.

Objectives

To validate the Spanish mYFAS 2.0; to analyse the relationships between FA with other eating behaviours, sociodemographic variables, and Body Mass Index (BMI); and to test the eating-related variables that account for the variance in FA.

Methods

The sample consisted of 400 university students (Mage = 24.16, SDage = 6.12; 51% female), who completed the mYFAS 2.0 and measures of eating-related constructs.

Results

A confirmatory factor analysis (CFA) supported the one-factor structure of the mYFAS 2.0. The scale showed good internal consistency (α = .78), and good convergent validity with the mYFAS. FA was related to eating styles, binge eating, and bulimia. No differences in FA were observed between males and females, and there was no association between FA and BMI. In addition, younger participants scored higher on FA than older participants. The eating-related variables explain 54.7% of the variance in FA.

Conclusions

The mYFAS 2.0 is a valid and reliable scale to assess FA in the Spanish population. The positive and significant relationship of variables related to eating (eating styles, binge eating and bulimia) with FA was demonstrated. These variables were indicated by those at high risk of FA.
A randomised controlled feasibility study of food-related computerised attention training versus mindfulness training and waiting-list control for adults with overweight or obesity: the FOCUS study
Authors: Mercado Daniela , Werthmann Jessica , Antunes-Duarte Tiago , Campbell Iain C. , Schmidt Ulrike
Published: April 2023

Background

In a feasibility randomised controlled trial in people with overweight/obesity with and without binge eating disorder (BED) symptoms, we assessed eight weekly sessions of attention bias modification training (ABMT) and mindfulness training (MT) versus waiting list (WL) and explored potential mechanisms.

Methods

45 participants were randomly allocated to one of three trial arms. Primary outcomes were recruitment, retention and treatment adherence rates. Secondary outcomes included measures of eating behaviour, mood, attention and treatment acceptability. Assessments were conducted at baseline, post-intervention (week 8), and follow-up (week 12).

Results

Participant retention at follow-up was 84.5% across groups. Session completion rates in the laboratory were 87% for ABMT and 94% for MT, but home practice was much poorer for ABMT. Changes in BMI and body composition were small between groups and there was a medium size BMI reduction in the MT group at follow-up. Effect sizes of eating disorder symptom changes were not greater for either intervention group compared to WL, but favoured ABMT compared to MT. Hedonic hunger and mindful eating scores favoured MT compared to ABMT and WL. ABMT reduced attention biases towards high-calorie food cues, which correlated with lower objective binge eating days at post-intervention. No significant changes were observed in the MT, or WL conditions.

Conclusions

Both ABMT and MT have potential value as adjuncts in the treatment of obesity and BED, and a larger clinical trial appears feasible and indicated.

Movement disorders (MD) have been linked to degeneration of the substantia nigra (SN) in Parkinson’s disease and include bradykinesia, rigidity, and tremor. They are also present in frontotemporal dementia (FTD), where MD have been linked to frontotemporal lobar degeneration with tau pathology (FTLD-tau). Although MD can also occur in FTLD with TDP-43 pathology (FTLD-TDP), the local pathology in the SN of FTLD-TDP patients with MD is currently unexplored. The aims of this study are to characterize the frequency and the nature of MD in a cohort of FTLD-TDP brain donors and to investigate the relationship between the presence of MD, the nigral neuronal loss, and the TDP-43 burden in the SN. From our cohort of FTLD-TDP patients (n = 53), we included 13 donors who presented with MD (FTLD-MD+), and nine age-sex matched donors without MD (FTLD-MD-) for whom the SN was available. In these donors, the TDP-43 burden and the neuronal density in the SN were assessed with ImageJ and Qupath software. The results were compared between the two groups using T-test. We found that the TDP-43 burden in the SN was higher in FTLD-MD+ (mean 3,43%, SD ± 2,7) compared to FTLD-MD- (mean 1,21%, SD ± 0,67) (p = 0,04), while no significant difference in nigral neuronal density was found between the groups (p = 0,09). 17% of FTLD-TDP patients developed MD, which present as symmetric akinetic-rigid parkinsonism or CBS. Given the absence of a significant nigral neuronal cell loss, TDP-43 induced neuronal dysfunction could be sufficient to cause MD.
