Published: November 2020

Background

The clinicopathological classification of breast cancer is proposed according to therapeutic purposes. It is simplified and can be conducted easily in clinical practice, and this subtyping undoubtedly contributes to the treatment selection of breast cancer. This study aims to investigate the feasibility of using a Fisher discriminant analysis model based on radiomic features of diffusion-weighted MRI for predicting the clinicopathological subtypes of breast cancer.

Methods

Patients who underwent breast magnetic resonance imaging were confirmed by retrieving data from our institutional picture archiving and communication system (PACS) between March 2013 and September 2017. Five clinicopathological subtypes were determined based on the status of ER, PR, HER2 and Ki-67 from the immunohistochemical test. The radiomic features of diffusion-weighted imaging were derived from the volume of interest (VOI) of each tumour. Fisher discriminant analysis was performed for clinicopathological subtyping by using a backward selection method. To evaluate the diagnostic performance of the radiomic features, ROC analyses were performed to differentiate between immunohistochemical biomarker-positive and -negative groups.

Results

A total of 84 radiomic features of four statistical methods were included after preprocessing. The overall accuracy for predicting the clinicopathological subtypes was 96.4% by Fisher discriminant analysis, and the weighted accuracy was 96.6%. For predicting diverse clinicopathological subtypes, the prediction accuracies ranged from 92 to 100%. According to the cross-validation, the overall accuracy of the model was 82.1%, and the accuracies of the model for predicting the luminal A, luminal BHER2-, luminal BHER2+, HER2 positive and triple negative subtypes were 79, 77, 88, 92 and 73%, respectively. According to the ROC analysis, the radiomic features had excellent performance in differentiating between different statuses of ER, PR, HER2 and Ki-67.

Conclusions

The Fisher discriminant analysis model based on radiomic features of diffusion-weighted MRI is a reliable method for the prediction of clinicopathological breast cancer subtypes.

Authors: Høydahl Øystein , Edna Tom-Harald , Xanthoulis Athanasios , Lydersen Stian , Endreseth Birger Henning
Published: November 2020

Background

The purpose of this study was to assess trends in incidence and presentation of colorectal cancer (CRC) over a period of 37 years in a stable population in Mid-Norway. Secondarily, we wanted to predict the future burden of CRC in the same catchment area.

Methods

All 2268 patients diagnosed with CRC at Levanger Hospital between 1980 and 2016 were included in this study. We used Poisson regression to calculate the incidence rate ratio (IRR) and analyse factors associated with incidence.

Results

The incidence of CRC increased from 43/100,000 person-years during 1980–1984 to 84/100,000 person-years during 2012–2016. Unadjusted IRR increased by 1.8% per year, corresponding to an overall increase in incidence of 94.5%. Changes in population (ageing and sex distribution) contributed to 28% of this increase, whereas 72% must be attributed to primary preventable factors associated with lifestyle. Compared with the last observational period, we predict a further 40% increase by 2030, and a 70% increase by 2040. Acute colorectal obstruction was associated with tumours in the left flexure and descending colon. Spontaneous colorectal perforation was associated with tumours in the descending colon, caecum, and sigmoid colon. The incidence of obstruction remained stable, while the incidence of perforation decreased throughout the observational period. The proportion of earlier stages at diagnosis increased significantly in recent decades.

Conclusion

CRC incidence increased substantially from 1980 to 2016, mainly due to primary preventable factors. The incidence will continue to increase during the next two decades, mainly due to further ageing of the population.
Microincision vitrectomy surgery: experimental visualization and quantification of vitreous contamination
Authors: Machida Yumiko , Nakashizuka Hiroyuki , Shoji Jun , Shimada Hiroyuki
Published: November 2020

Background

To visualize and quantify vitreous contamination following microincision vitrectomy surgery (MIVS) using an experimental vitreous contamination model (EVCM).

Methods

Enucleated porcine eyes with fluoresbrite carboxylate microspheres applied to the conjunctival surface were used as a type 1 EVCM. Twenty-five- or 27-gauge (G) trocar cannulas were inserted through the conjunctiva and sclera, followed by the placing and opening of an infusion cannula. These procedures were monitored by an intraocular fiber catheter. Secondly, condensed microspheres were applied to an excised sheet of porcine sclera to serve as type 2 EVCM. Twenty-five- or 27-G trocar cannulas were inserted perpendicularly through the top of the sclera where the condensed microspheres were applied, an infusion cannula was inserted, 0.1 mL of saline solution injected through the infusion cannula, and samples collected. The fluorescence strength of samples was then measured using fluorophotometry.

Results

We visually detected fluorescent microspheres in 10/10 eyes with 25-G and 10/10 with 27-G MIVS. In the experimental quantification study, each MIVS gauge value was significantly higher than the control (P < 0.01). However, there was no significant difference between 25-G and 27-G MIVS.

Conclusions

MIVS carries the risk of introducing contamination directly into the eyes when the trocar cannula is inserted and infusion cannula is opened, even when a 27-G MIVS is used. Our study has shown it is essential that the surgeon be aware of the possibility of introducing contamination from the conjunctiva at all times during MIVS.
Clinical characteristics, treatment, and long-term outcomes in children suffering from benign convulsions with mild gastroenteritis: a retrospective study
Authors: Hao Xiao-sheng , Liang Jian-min , Wu Xue-mei , Hao Yun-peng , Wang Jiang-tao , Liu Song-yan
Published: November 2020

Background

Benign convulsions with mild gastroenteritis (BCWG) is a common condition in children in Asia and is generally not associated with pH or electrolyte imbalances. When BCWG is diagnosed, a lumbar puncture is usually recommended to rule out potential intracranial infections. This study examined the clinical characteristics of BCWG and evaluated the necessity of lumbar puncture.

Methods

Medical records of children admitted to the First Hospital of Jilin University with BCWG between January 2018 and May 2019 were reviewed and analyzed. Children were stratified by rotavirus positivity or lumbar puncture status. Clinical characteristics and long-term outcomes were compared between groups.

Results

A total of 51 children were included in the analyses (55.1% rotavirus [HRV] positive). The average age of convulsion onset was 21.12 ± 7.44 months, the male-to-female ratio was 1.8:1, and convulsions occurred primarily between October 2018 and April 2019. The main clinical presentations of BCWG were convulsions, vomiting, diarrhea, and fever. Convulsions occurred predominantly two days after diagnosis of gastroenteritis, were mainly generalized tonic-clonic with 88.2% of children having ≤ 3 convulsions per episode, and had a mean duration of 2.0 minutes (interquartile range [IQR]: 1.0, 3.0). Children with BCWG had mild metabolic acidosis (HCO3− 17.82 ± 3.63 mmol/L) with an elevated anion gap (AG; 20.98 ± 3.00 mmol/L), mild hyponatremia (134.56 ± 2.85 mmol/L), and slightly increased levels of creatine kinase myocardial band (CKMB). HRV + children had more severe acidosis and higher CKMB levels. Cerebrospinal fluid (CSF) samples collected via lumbar puncture were normal. No developmental abnormalities were noted as assessed by the Social Life Ability Scale.

Conclusions

BCWG is a situation-related seizure, with clinical presentations of tonic-clonic or focal convulsions and mild gastroenteritis (vomiting, diarrhea). Mild metabolic acidosis and hyponatremia may exist. The prognosis of the disease is favorable; lumbar puncture and long-term antiepileptics are unnecessary and should not be recommended.
‘The mean mummy way’ – experiences of parents instilling eye drops to their young children as described in online forums and blogs
Authors: Law Gloria C. , Bülbül Alpaslan , Jones Christina J. , Smith Helen
Published: November 2020

Background

Adults often have difficulty instilling eye drops in their own eyes, but little has been documented about the difficulties experienced by parents when administering eye drops to their young children, where the challenges of instillation are accentuated by their inability to cooperate. This qualitative study explores parents’ experiences of administering eye drops to their children as described in online forum discussions and blog posts.

Methods

This was an exploratory study using qualitative methods. We thematically analysed the written exchanges between parents participating in online forum discussions and blog posts about the administration of eye drops to their young children.

Results

We found 64 forum discussion threads and 4 blog posts, representing 464 unique contributors expressing their experiences of eye drop administration to young children. Three major themes were identified – administration challenges, administration methods and role of health care professionals. Besides describing their children’s distress, parents discussed their own discomfort and anxiety when administering eye drops. Parents used a variety of techniques to facilitate adherence with medication, including restraining the child, role-play, reassurance, distraction, or reward. The ideas exchanged about eye drop administration occasionally included reiteration of professional advice, but were dominated by parents’ own ideas/suggestions; interestingly health care professionals were considered diagnosticians and prescribers, rather than sources of practical advice on administration.

Conclusions

Parents struggling to deliver eye drops to their young children may seek advice on how to administer treatment from parental on-line discussion forums. The distress experienced by the young child and their parents is a powerful reminder to clinicians that procedures common and routine in health care may be challenging to parents. The advice given to parents needs to go beyond the instillation of the eye drops, and include advice on child restraint, distraction techniques and allaying distress. Forewarned of the potential difficulties and provided with coping strategies parents can employ when the child resists, could alleviate their own and their child’s distress.

Authors: Li Xiaowei , Zhang Wanda , Zhang Weiya , Tao Ke , Ni Wenli , Wang Kai , Li Zhanglai , Liu Qiang , Lin Jianhao
Published: November 2020

Background

With data from different regions accumulated, physical inactivity (PI) was found to be pandemic worldwide. Using China Health and Retirement Longitudinal Study (CHARLS), a nationwide longitudinal survey data, we aimed to delineate the prevalence, incidence and risk factors of physical inactivity (PI) among Chinese people aged 45 years and older.

Methods

The CHARLS covered nearly all provinces, autonomous regions, municipalities of mainland China. With data from CHARLS, three cross-sectional analyses and a cohort analysis were conducted. In cross-sectional studies, we used surveys at 2011, 2013 and 2015 to examine the prevalence and its trend of PI. Multivariate generalized linear model was conducted in survey at 2011 to examine the risk factors for prevalent PI. Multiple imputation of missing values was used and results before and after imputation were compared. In cohort analysis, we identified people free of PI at 2011 and followed them up until 2015 to estimate the incidence of PI. Generalized estimating equation was used to examine the risk factors associated with incidence PI. In all analyses, PI was defined as insufficient physical activity according to the International Physical Activity Questionnaire (IPAQ) criterion.

Results

6650, 5946 and 9389 participants were eligible for cross-sectional analyses, and 4525 participants were included for cohort analysis. The weighted prevalence of PI was 22.25% (95% CI: 20.63–23.95%) in 2011, 20.64% (95% CI: 19.22–22.14%) in 2013 and 19.31% (95% CI: 18.28–20.38%) in 2015. In multivariate analysis, PI was associated with older age, higher education, overweight, obesity and difficulties in daily living, and was negatively associated with working and higher level of expenditure. No material change was detected in results after multiple imputation. In cohort analysis, older age, abundant public facilities, difficulties in daily living were identified as risk factors of incidence PI, while urban areas, college and above education, and working were protective factors.

Conclusions

PI is pandemic in 45 years and older people in China. People with older age, difficulties in daily living and people who are not working are at higher risk. More efforts should be paid in estimating and promoting leisure-time physical activities.

Published: November 2020

Background

Respiratory tract infections are one of the common infection associated with Hajj pilgrimage that is of great public health and global concern. This study is aimed at determining the factor structure of the knowledge, attitude, and practice questionnaire for the prevention of respiratory tract infections during Hajj by confirmatory factor analysis (CFA).

Methods

A multistage cluster sampling method was conducted on Malaysian Umrah pilgrims during the weekly Umrah orientation course. A total of 200 Umrah pilgrims participated in the study. The knowledge, attitude and practice (KAP) questionnaire was distributed to pilgrims at the beginning of the orientation and retrieved immediately at the end of the orientation. Data analysis was done using R version 3.5.0 after data entry into SPSS 24. The robust maximum likelihood was used for the estimation due to the multivariate normality assumption violation. A two-factor model was tested for measurement model validity and construct validity for each of the attitude and practice domains.

Results

CFA of a 25-item in total, the two-factor model yielded adequate goodness-of-fit values. The measurement model also showed good convergent and discriminant validity after model re-specification. A two-factor model was tested for measurement model validity and construct validity for each of the attitude and practice domains. The result also showed a statistically significant value (p < 0.001) with χ2(df) values of 76.8 (43) and 121 (76) for attitude and practice domains, respectively.

Conclusion

The KAP questionnaire was proven to have a valid measurement model and reliable constructs. It was deemed suitable for use to measure the KAP of Hajj and Umrah pilgrims towards the prevention for all respiratory tract infections.

Authors: Voss Sidsel Skou , Glode Helmuth Ida , Hiul Suppli Camilla , Valentiner-Branth Palle
Published: November 2020

Background

In Denmark, vaccination coverage is measured using the Danish Vaccination Register (DDV). In general, the vaccination coverage is high, but for some vaccinations, the coverage is suboptimal with geographical variation. This study aims to validate the vaccination coverage of the 5-year booster and identify overall reasons for non-vaccination in Copenhagen.

Methods

We validated the coverage of the 5-year tetanus, diphtheria, pertussis and polio booster for children born in 2010 and living in Copenhagen municipality in 2018, an area with low coverage (current estimate: 89%). We identified all children born in 2010 in the Civil Registration System and sent an electronic questionnaire to parents of children without a record of the 5-year booster in the DDV.

Results

Parents of 692 children were contacted and 49% participated. Of those, 186 (55%) reported that the child was vaccinated: 61% by their general practitioner and 34% abroad. The most common reason for non-vaccination was forgetfulness (31%), 26% did not want their child vaccinated and 17% had migrated from abroad and were not aware of the vaccination schedule. Considering only children with documentation for the vaccination, the corrected vaccination coverage was 91%.

Conclusions

We conclude that the coverage of the 5-year booster in Copenhagen is currently underestimated and should be adjusted by 2%. We recommend increased awareness from general practitioners and tailored communication about the vaccination programme targeting immigrants in Denmark.
Pulmonary benign metastasizing leiomyomas: a case series of 23 patients at a single facility
Authors: Fan Rong , Feng Fengzhi , Yang Hua , Xu Kaifeng , Li Shanqing , You Yan , Wan Xirun , Zhu Lan
Published: November 2020

Background

Pulmonary benign metastasizing leiomyoma (PBML) is a rare disease characterized by leiomyoma of benign histopathology existing in the lungs. Because of its rarity, limited literature with a single case or small number of cases has been regarding to the clinical course, pathology or management of PBML.

Methods

A retrospective study was performed of all PBML cases diagnosed and managed at Peking Union Medical College Hospital (PUMCH) from 2001 to 2019. The clinical characteristics, pathology, treatment and outcomes of each case were studied.

Results

There were 25 PBML patients identified in the 19-year period in PUMCH, and 23 patients’ data was analyzed. The median age at diagnosis was 46 years. There were 7 patients (30.4%) diagnosed with postmenopausal status. Two patients (8.7%) had no uterine leiomyoma, and 3 patients (13.0%) had no gynecologic surgery history. Immunohistochemistry of most lesions demonstrated positive for desmin, SMA and Estrogen/Progesterone Receptors; and negative for S-100 were shown in 7 cases. After curative or diagnostic surgeries for the PBML, several treatments from observation to medical or surgical castration were performed. Nine premenopausal patients preserved their ovaries at first. At a median follow-up of 8 years, 3 patients finally had oophorectomy.

Conclusions

PBML is a rare disease and should be treated by individualization according to the patients’ age, symptoms and extent of lesion. Curative surgery for patients with limited lesions can achieve the complete response. For patients that are young and asymptomatic, close observation is recommended as the first choice. All patients should undergo long-term surveillance.

Intensity of resistance training via self-reported history is critical in properly characterizing musculoskeletal health
Authors: Shoepe Todd C. , LaBrie Joseph W. , Mello Grant T. , Leggett Allison G. , Almstedt Hawley C.
Published: November 2020

Background

Intensity of resistance training history might be omitted or poorly ascertained in prescreening or data questionnaires involving musculoskeletal health. Failure to identify history of high-versus low-intensity training may overlook higher effect sizes with higher intensities and therefore diminish the precision of statistical analysis with resistance training as a covariate and bias the confirmation of baseline homogeneity for experimental group designation. The purpose was to determine the degree to which a single question assessing participant history of resistance training intensity predicted differences in musculoskeletal health.

Methods

In the first research aim, participants were separated into groups with a history (RT) and no history (NRT) of resistance training. The second research aim evaluated the history of resistance trainingintensityon muscular strength, lean mass, and bone mineral density (BMD), RT participants were reassigned into a low- (LIRT) or high-intensity resistance training group (HIRT). 83 males and 87 females (19.3 ± 0.6 yrs., 171.1 ± 9.9 cm, 67.1 ± 10.5 kg, 22.9 ± 2.8 BMI, 26.2 ± 7.2% body fat) completed handgrip dynamometry (HG) and dual-energy x-ray absorptiometry scans (DXA) for BMD and bone mineral-free lean mass (BFLM).

Results

A 3-group method (NRT, LIRT, HIRT) reduced type-I error compared with the 2-group method (NRT, RT) in characterizing the likely effects of one’s history of resistance training. For the second aim, HIRT had significantly (p < 0.05) greater HG strength (76.2 ± 2.2 kg) and arm BFLM (6.10 ± 0.16 kg) than NRT (67.5 ± 1.3 kg; 4.96 ± 0.09 kg) and LIRT (69.7 ± 2.0 kg; 5.42 ± 0.14 kg) while also showing significantly lower muscle quality (HG/BFLM) than NRT (13.9 ± 0.2 vs. 12.9 ± 0.3). HIRT had greater BMD at all sites compared to NRT (whole body = 1.068 ± 0.008 vs. 1.120 ± 0.014; AP spine = 1.013 ± 0.011 vs. 1.059 ± 0.019; lateral spine = 0.785 ± 0.009 vs. 0.846 ± 0.016; femoral neck = 0.915 ± 0.013 vs. 0.970 ± 0.022; total hip = 1.016 ± 0.012 vs. 1.068 ± 0.021 g/cm2) while LIRT revealed no significant skeletal differences to NRT.

Conclusions

Retrospective identification of high-intensity history of resistance training appears critical in characterizing musculoskeletal health and can be ascertained easily in as little as a single, standalone question. Both retrospective-questionnaire style investigations and pre-screening for potential participation in prospective research studies should include participant history of resistance trainingintensity.

Published: November 2020

Background

Aggressive angiomyxoma (AA) is a rare tumor that typically occurs in the pelvis and perineum, most commonly in women of reproductive age. However, no para-ureteral AA has been reported according to the literature.

Case presentation

We herein describe the first case of para-ureteral AA. A 62-year-old male presented to our institute in March 2017 with a para-ureteral mass that was 15 mm in diameter incidentally. No symptom was observed and laboratory analysis was unremarkable. Magnetic resonance and computed tomography imaging showed a non-enhancing mass abutting the left ureter without causing obstruction. Laparoscopic resection of the mass was performed without injury to the ureter. Pathologic and immunohistochemical results were consistent with AA. Till now, no recurrence was noticed.

Conclusions

We reported a rare case of para-ureteral AA, along with a literature review. Early diagnosis, proper surgical plan and long-term close follow-up is recommended for its high risk of recurrence and malignant potential.
Comparing zirconia to anterior strip crowns in primary anterior teeth in children: a randomized clinical trial
Authors: Alaki Sumer M. , Abdulhadi Bashaer S. , AbdElBaki Medhat A. , Alamoudi Najlaa M.
Published: November 2020

Background

Providing restorations to anterior teeth in children is a challenging task due to the need for high esthetics, strength, and durability. This study was done to compare prefabricated primary zirconia with resin composite strip crowns on primary maxillary central and lateral incisors with regards to gingival health, plaque accumulation, recurrent caries, restoration failure, and opposing teeth wear over a period of 3, 6 and 12 months.

Methods

Children attending the King Abdulaziz University, Faculty of Dentistry (KAUFD) clinics who needed restorations were screened for inclusion criteria. A total of 120 teeth were treated; 60 with zirconia and 60 with strip crowns. Randomization was done by simple random allocation using SPSS software version 20.0 (Armonk, NY; IBM Corp.). A simple descriptive statistic was used for analysis by Wilcoxon Signed-Rank test and Chi-square test. Level of significance was set at (α = 0.05) and level of confidence at (95%). The presented research was registered retrospectively at ClinicalTrials.gov in 6th of August 2017, under registration number NCT03184012.

Results

Zirconia crowns showed significantly less gingival bleeding at the 3- and 6-months follow up periods (p < 0.006, p < 0.001; respectively), less plaque accumulation at all follow up visits (p < 0.001), no restoration failure (p < 0.001), but more wear to opposing teeth (p < 0.02). No significant difference was found between the two crowns with regards to recurrent caries (p < 0.135).

Conclusion

Based on our data we conclude that overtime teeth covered with zirconia crowns show better gingival health and less bleeding, plaque accumulation as well as less loss of material. On the other hand, zirconia can cause more loss of opposing tooth structure.
Introducing cross-cultural education in palliative care: focus groups with experts on practical strategies
Authors: Semlali Imane , Tamches Emmanuel , Singy Pascal , Weber Orest
Published: November 2020

Background

The linguistic and cultural diversity found in European societies creates specific challenges to palliative care clinicians. Patients’ heterogeneous habits, beliefs and social situations, and in many cases language barriers, add complexity to clinicians’ work. Cross-cultural teaching helps palliative care specialists deal with issues that arise from such diversity. This study aimed to provide interested educators and decision makers with ideas for how to implement cross-cultural training in palliative care.

Methods

We conducted four focus groups in French- and Italian-speaking Switzerland. All groups consisted of a mix of experts in palliative care and/or cross-cultural teaching. The interdisciplinary research team submitted the data for thematic content analysis.

Results

Focus-group participants saw a clear need for courses addressing cross-cultural issues in end-of-life care, including in medical disciplines outside of palliative care (e.g. geriatrics, oncology, intensive care). We found that these courses should be embedded in existing training offerings and should appear at all stages of curricula for end-of-life specialists. Two trends emerged related to course content. One focuses on clinicians’ acquisition of cultural expertise and tools allowing them to deal with complex situations on their own; the other stresses the importance of clinicians’ reflections and learning to collaborate with other professionals in complex situations. These trends evoke recent debates in the literature: the quest for expertise and tools is related to traditional twentieth century work on cross-cultural competence, whereas reflection and collaboration are central to more recent research that promotes cultural sensitivity and humility in clinicians.

Conclusion

This study offers new insights into cross-cultural courses in palliative and end-of-life care. Basic knowledge on culture in medicine, variable practices related to death and dying, communication techniques, self-reflection on cultural references and aptitude for interprofessional collaboration are central to preparing clinicians in end-of-life settings to work with linguistically and culturally diverse patients.
A qualitative study of clinical narrative competence of medical personnel
Authors: Chu Shao-Yin , Wen Chin-Chen , Lin Chi-Wei
Published: November 2020

Background

Medicine practiced with narrative competence is called narrative medicine, which has been proposed and used as a model of humane and effective medical practice. Despite the in-depth discussions of narrative medicine, the study of narrative competence in literature is limited; therefore, this study aims to explore the dimensions and connotations of the clinical narrative competence of medical personnel.

Methods

This qualitative study used in-depth interviews to collect participants’ experience and perspectives regarding narrative competence, followed by thematic analysis of the transcripts.Through purposive sampling, this study successfully recruited 15 participants (nine males and six females in 2018–2019) who were engaged in narrative medicine or medical humanity education from different medical schools and hospitals across Taiwan. The authors performed manual thematic analysis to identify the themes and concepts of narrative competence through a six-step theme generation process.

Results

There were four major themes of narrative competence generalized and conceptualized: narrative horizon, narrative construction (including narrative listening, narrative understanding, narrative thinking, and narrative representation), medical relationship (including empathy, communication, affiliation, and inter-subjectivity), and narrative medical care (including responsive care, balanced act, and medical reflection). These four themes were further integrated into a conceptual framework and presented in a diagram.

Conclusions

Cultivating narrative competence in medical education can complement traditional biomedical orientation. Regardless of their treatment orientation, narrative medicine-informed health practitioners may take advantage of their multi-dimensional narrative competence, as presented in this article, to enhance their awareness and preparation in different areas of competence in medical services. In addition, the results of this study can be used as a framework for the development of the behavioral indicators of narrative competence, which can be taken as the basis for medical education curriculum design.

Published: November 2020

Background

Croatia has closed all educational institutions after 32 cases of SARS-CoV-2 infection were confirmed and switched to exclusive e-learning. Health sciences university students may have been particularly affected with this change due to a lack of practical education. It is not known how health sciences students and schools have adjusted to exclusive e-learning. This study aimed to explore attitudes and concerns of health sciences students in Croatia regarding the complete switch to e-learning during the COVID-19 pandemic.

Methods

Eligible participants were students from 9 institutions offering university-level health sciences education in Croatia enrolled in the academic year 2019/2010, and participating in e-learning. Data were collected with a questionnaire distributed via email during April/May 2020.

Results

A total of 2520 students (aged 25.7 ± 7.7 years) responded to the questionnaire (70.3% response rate). General satisfaction with exclusive e-learning was rated with average grade of 3.7 out of 5. Compared with previous education, exclusive e-learning was rated with average grade of 3.2 out of 5. Compared to classroom learning, equal or higher motivation to attend exclusive e-learning was reported by 64.4% of participants. With a longer duration of exclusive e-learning, equal or higher motivation was reported by 65.5% of participants. Less than half of the students indicated they felt deprived or concerned due to the lack of practical lessons. Most participants indicated that in the future, they would prefer to combine classic classroom and e-learning (N = 1403; 55.7%).

Conclusions

Most health sciences students were satisfied with the exclusive e-learning, as well as their personal and institutional adjustment to it. Students’ feedback can help institutions to improve the exclusive e-learning experience for students in the time of the pandemic.
Medical identity; perspectives of students from two countries
Authors: Gilligan Conor , Loda Teresa , Junne Florian , Zipfel Stephan , Kelly Brian , Horton Graeme , Herrmann-Werner Anne
Published: November 2020

Background

The development of professional identity is a fundamental element of medical education. There is evidence that in Germany, students’ perceptions of the ideal and real doctor differ, and that of themselves as physicians falls between these constructs. We sought to compare students’ perceptions of themselves, the ideal doctor, and the ‘real’ doctor and investigate differences from first to final year in the relationships between these constructs, as well as differences between Australian and German cohorts.

Method

Students in the first and final years of their medical program at one Australian and one German university were invited to complete the Osgood and Hofstatter polarity profile, involving the description of their mental image of the ideal and real doctor, and the doctor they hope to become, with adjectives provided.

Results

One hundred sixty-seven students completed the survey in Australia (121 year 1, 46 year 5) and 188 in Germany (164 year 1, 24 year 6). The perception of the ideal doctor was consistent across all respondents, but that of the real doctor and self-image differed between country and year. Differences existed between country cohorts in perceptions of ‘confidence’, ‘strength’, ‘capability’ and ‘security’.

Conclusions

The pattern previously reported among German students was maintained, but a different pattern emerged among Australian students. Differences between countries could reflect cultural differences or variations in the overt and hidden curricula of medical schools. Some of the constructs within the profiles are amenable to educational interventions to improve students’ confidence and sense of capability.
Implementation and factors affecting the nursing process among nurses working in selected government hospitals in Southwest Ethiopia
Authors: Adraro Zerihun , Mengistu Daniel
Published: November 2020

Background

The nursing process was initially adopted from the general system theory, and was developed and implemented in the field of education. There is a demand to implement the nursing process in practical care in every health institution, but the perception remains that it is time-consuming and impractical. If the nursing process is not valued and not used, nurses may continue to intervene on the basis of a medical diagnosis rather than on the basis of a rational nursing Process steps. In any of the steps, oversight or omission can result in less than optimal nursing care. The purpose of this study was to assess implementation and factors affecting the nursing process among nurses working in selected government hospitals in Southwest Ethiopia.

Methods

An institution-based cross-sectional descriptive study was conducted from March 10 to April 1, 2015 in three hospitals in southwest Ethiopia using self-administered questionnaires. This study included a total of 138 nurses using simple random sampling. Data were classified, coded and entered into epidemiological information version 3.5.3, and exported to the statistical package for social science version 20 for analysis, descriptive statistics were used to describe the variables, bivariable and multivariable logistic regression were used to see the effect of each variable on the dependent variable.

Result

The nursing process was found to be 73.9% implemented. Compared to a Bachelor of Science nurses’, the likelihood of implementing the nursing process was less likely among diploma nurses. Nurses working in administratively supported hospitals implemented the nursing process more compared to those without administrative support. The nursing process had been implemented higher by trained nurses compared to untrained nurses.

Conclusion

The implementation of nursing process was good where; nearly seven in every ten nurses implemented the nursing process. Low educational qualification, lack of training, and non-supportive hospital administration were predictors of the nursing process implementation. The health service management, in collaboration with Ethiopian nursing/professional associations and international governmental and non-governmental organizations should give continuous on the job professional development education, and develop nursing practice guidelines.
“Vital”: HIV counselling and testing staff’s views of addressing mental health with HIV in Uganda
Authors: Martin Faith , Nalukenge Winfred , Lazarus Oucul , Birungi Josephine , Seeley Janet
Published: November 2020

Background

Mental health is linked to HIV outcomes, including linkage into care and adherence to medication. Integrated care for mental and physical health is recommended. HIV testing and counselling sessions represent an opportunity to implement interventions to address mental health, however it is first necessary to understand the roles, current practice, knowledge and attitudes of the testing and counselling staff.

Methods

This qualitative study used semi-structured interviews with HIV testing and counselling staff at four centres of a HIV healthcare provider charity in Uganda. Interviews focused on their current practice, perceptions of mental health and their role in supporting this, challenges of this work, training and support needs, and views of potential greater emphasis on mental health work in their role. Data were audio-recorded, transcribed verbatim, and analysed thematically.

Results

Data from twenty-one testing and counselling staff revealed five themes. Clients presented to counselling staff with needs spanning bio-psycho-social domains, where psychological health was intertwined with HIV management, medication adherence, and seen as “inseparable” from HIV itself. Mental health was largely thought about as “madness”, identifiable from extreme behaviour. As such, common mental health problems of anxiety and depression were not often seen as part of mental health. Approaches to intervening with mental health were seen as behavioural, with some ideas about changing thinking styles. Participants demonstrated significant practice of common techniques to address mental health. Needs were identified for further training in suicide risk assessment and identification of depression, together with greater clinical supervision. Participants described significant conflict within their roles, particularly balancing time demands and need to achieve testing targets against the need to offer adequate mental health support to clients in need.

Conclusions

HIV testing and counselling staff described a diverse role that already includes addressing mental health. Mental health is “vital” to their work, however the time needed to address it is at odds with current testing targets. They require more training and resources to effectively address mental health, which is vital to optimising HIV outcomes. Interventions to integrate mental health support into HIV testing and counselling sessions need to be further researched and optimised.
Mendelian randomization study of inflammatory bowel disease and bone mineral density

Background

Recently, the association between inflammatory bowel disease (including ulcerative colitis and Crohn’s disease) and BMD has attracted great interest in the research community. However, the results of the published epidemiological observational studies on the relationship between inflammatory bowel disease and BMD are still inconclusive. Here, we performed a two-sample Mendelian randomization analysis to investigate the causal link between inflammatory bowel disease and level of BMD using publically available GWAS summary statistics.

Methods

A series of quality control steps were taken in our analysis to select eligible instrumental SNPs which were strongly associated with exposure. To make the conclusions more robust and reliable, we utilized several robust analytical methods (inverse-variance weighting, MR-PRESSO method, mode-based estimate method, weighted median, MR-Egger regression, and MR.RAPS method) that are based on different assumptions of two-sample MR analysis. The MR-Egger intercept test, Cochran’sQtest, and “leave-one-out” sensitivity analysis were performed to evaluate the horizontal pleiotropy, heterogeneities, and stability of these genetic variants on BMD. Outlier variants identified by the MR-PRESSO outlier test were removed step-by-step to reduce heterogeneity and the effect of horizontal pleiotropy.

Results

Our two-sample Mendelian randomization analysis with two groups of exposure GWAS summary statistics and four groups of outcome GWAS summary statistics suggested a definitively causal effect of genetically predicted ulcerative colitis on TB-BMD and FA-BMD but not on FN-BMD or LS-BMD (after Bonferroni correction), and we merely determined a causal effect of Crohn’s disease on FN-BMD but not on the others, which was somewhat inconsistent with many published observational researches. The causal effect of inflammatory bowel disease on TB-BMD was significant and robust but not on FA-BMD, FN-BMD, and LS-BMD, which might result from the cumulative effect of ulcerative colitis and Crohn’s disease on BMDs.

Conclusions

Our Mendelian randomization analysis supported the causal effect of ulcerative colitis on TB-BMD and FA-BMD. As to Crohn’s disease, only the definitively causal effect of it on decreased FN-BMD was observed. Updated MR analysis is warranted to confirm our findings when a more advanced method to get less biased estimates and better precision or GWAS summary data with more ulcerative colitis and Crohn’s disease patients was available.

Background

With an increasing clinical importance of the treatment of the heart failure (HF) with preserved ejection fraction (HFpEF), it is important to be certain of the diagnosis of HF. We investigated global and regional left ventricular (LV) strains using speckle tracking echocardiography (STE) in patients with HFpEF and compared those parameters with that of patients with hypertension and normal subjects.

Methods

Peak longitudinal, circumferential and radial strains were assessed globally and regionally for each study groups using STE. Diastolic strain rate was also determined.

Results

There were 50 patients in HFpEF group, 56 patients in hypertension group and 46 age-matched normal subjects. In patients with HFpEF, global peak longitudinal, circumferential and radial strain and strain rate were reduced compared to both hypertension patients and normal controls (− 15.5 ± 5.3 vs − 17.7 ± 3.1 and − 19.9 ± 2.0; − 9.7 ± 2.2 vs − 19.3 ± 3.1 and − 20.5 ± 3.3; 17.7 ± 8.2 vs 38.4 ± 12.4 and 43.6 ± 11.9, respectively, P <  0.001, for all). The diagnostic performance of global circumferential strain to predict the HFpEF was greatest among strain parameters (area under the curve = 0.997).

Conclusions

In the speckle tracking echocardiography, impaired peak global strain and homogeneously reduced regional strain was observed in HFpEF patients compared to the hypertension patients and normal subjects in decreasing order. This can provide early information on the initiation of LV deformation of HFpEF in patients with hypertension or normal subjects.

Background

Heavy tobacco smoking, a hallmark feature of lung cancer, is drastically predominant in Middle Eastern populations. The precise links between nicotine dependence and the functional contribution of the oral microbiota remain unknown in these populations.

Methods

We evaluated the composition and functional capabilities of oral microbiota with relation to cigarette smoking in 105 adults through shotgun metagenomics using buccal swabs.

Results

The oral microbiota composition in our study subjects was dominated by the phylaFirmicutes,Proteobacteria,Actinobacteria, andBacteroidetes, in addition to the generaPrevotellaandVeillonella,similar to previously described westernized cohorts. Furthermore, the smoker's oral microbiota represented a significant abundance ofVeillonella dispar,Leptotrichiaspp. andPrevotella pleuritidiswhen compared to non-smokers. Within the smoking groups, differential relative abundance testing unveiled relative abundance ofStreptobacillus hongkongensis,Fusobacterium massiliense,Prevotella biviain high nicotine dependent compared to low nicotine dependent profiles based on Fagerström Test for Nicotine Dependence. Functional profiling showed marked differences between smokers and non-smokers. Smokers exhibited an enrichment of Tricarballylate utilization and Lactate racemization when compared to the non-smokers. According to their nicotine dependence, enrichment of Xanthosine utilization, p-Aminobenzoyl-Glutamate utilization, and multidrug efflux pump inCampylobacter jejunibiosynthesis modules were detected in the high nicotine dependent group.

Conclusions

These compositional and functional differences may provide critical insight on how variations in the oral microbiota could predispose to respiratory illnesses and smoke cessation relapse in cigarette smokers. In particular, the observed enrichment ofFusobacteriumandPrevotellain the oral microbiota possibly suggests an intriguing linkage to gut and lung cancers.
