Abstract
Background
Suicide is the leading cause of death among Japanese adolescents. However, knowledge gaps regarding contemporary demographics and factors associated with suicidality among Japanese adolescents are a major concern. This study examined the prevalence of suicidality among Japanese adolescents and investigated associated factors.

Methods
A population-based questionnaire survey investigating general health was administered to 22,419 adolescents aged 13–18 years. The 29-item questionnaire covered emotional status, family function, cyberbullying, suicidality, and stressors (e.g., relationships with parents/friends, school performance, and sexual identity). We conducted multiple logistic regression analysis to identify factors associated with suicidality in this population.

Results
The prevalence of suicidal ideation was 21.6% in males and 28.5% in females, and that of attempted suicide was 3.5% in males and 6.6% and in females. Bullying and stress related to family relationships had the strongest associations with suicidality. Exposure to cyberbullying had the highest odds ratio for both junior high (3.1, 95% confidence interval [CI] 2.1–4.4) and high school students (3.6, 95% CI 2.5–5.3). Other factors significantly associated with suicidality were sex, emotional status, and stress about relationships with friends, sexual identity, school records, and academic course. Adolescents accessed a variety of resources to cope with stressors, with the Internet being the most common resource consulted.

Conclusions
Suicidality is commonly experienced among Japanese adolescents. Although there are many associated risk factors, cyberbullying is of particular concern. Recognition of factors associated with adolescent suicidality will inform further research and suicide prevention efforts for healthcare providers and families.

Abstract
Background
COVID-19 pandemic has created unprecedented health and economic impact. Psychological stress, anxiety and depression are affecting not only COVID-19 patients but also health professionals, and general population. Fear of contracting COVID-19, forced restrictive social measures, and economic hardship are causing mental trauma. Nepal is a developing country from South Asia where the COVID-19 pandemic is still evolving. This online survey has been carried out to understand impact of COVID- 19 on mental health of Nepalese community dwellers.

Methods
The COVID-19 Peritraumatic Distress Index (CPDI) questionnaire adapted from the Shanghai Mental Health Centre was used for online data collection from 11 April-17 May 2020. Collected data were extracted to Microsoft excel-13 and imported and analyzed using SPSS (Statistical Package for Social Sciences) version-22. An initial univariate analysis was conducted for all variables to assess the distribution. Logistic regression analyses were done to estimate the odds ratios of relevant predicting variables.

Results
A total of 410 participants completed the self-rated questionnaires. Mean age of study participants was 34.8 ± 11.7 years with male preponderance. 88.5% of the respondents were not in distress (score less than 28) while, 11% had mild to moderate distress and 0.5% had severe distress. The prevalence of distress is higher among age group > 45 years, female gender, and post-secondary education group. Health professional were more likely to get distressed. Respondents with post-secondary education had higher odds (OR = 3.32; p = 0.020) of developing distress as compared to respondents with secondary education or lower.

Conclusion
There is lower rate of psychological distress in city dwellers and people with low education. Adequate intervention and evaluation into mental health awareness, and psychosocial support focused primarily on health care workers, female and elderly individuals is necessary.
Socioeconomic inequality in short birth interval in Ethiopia: a decomposition analysis
Authors: Shifti Desalegn Markos , Chojenta Catherine , Holliday Elizabeth G. , Loxton Deborah 
Published: October 2020

Abstract
Background
Short birth interval, defined as a birth-to-birth interval less than 33 months, is associated with adverse maternal and child outcomes. Evidence regarding the association of maternal socioeconomic status and short birth interval is inconclusive. Factors contributing to the socioeconomic inequality of short birth interval have also not been investigated. The current study assessed socioeconomic inequality in short birth interval and its contributing factors in Ethiopia.

Methods
Data from 8448 women collected in the 2016 Ethiopia Demographic and Health survey were included in the study. Socioeconomic inequality in short birth interval was the outcome variable. Erreygers normalized concentration index (ECI) and concentration curves were used to measure and illustrate socioeconomic-related inequality in short birth interval, respectively. Decomposition analysis was performed to identify factors explaining the socioeconomic-related inequality in short birth interval.

Results
The Erreygers normalized concentration index for short birth interval was − 0.0478 (SE = 0.0062) and differed significantly from zero (P < 0.0001); indicating that short birth interval was more concentrated among the poor. Decomposition analysis indicated that wealth quintiles (74.2%), administrative regions (26.4%), and not listening to the radio (5.6%) were the major contributors to the pro-poor socioeconomic inequalities in short birth interval.

Conclusion
There was a pro-poor inequality of short birth interval in Ethiopia. Strengthening the implementation of poverty alleviation programs may improve the population’s socioeconomic status and reduce the associated inequality in short birth interval.
Increasing similarities between young adults’ smoking and snus use in Norway: a study of the trends and stages of smoking and snus epidemic from 2010 to 2018
Authors: Tjora Tore , Skogen Jens Christoffer , Sivertsen Børge 
Published: October 2020

Abstract
Background
The prevalence of smoking has been decreasing in Norway for decades. In contrast, the prevalence of snus use has recently increased substantially, especially among females. While there is a clear social gradient in smoking, with a higher smoking prevalence among individuals with low socioeconomic status (SES), a possible social gradient in snus use has been less studied. The aim of the current study was to investigate the trends of smoking and snus use and to examine whether ongoing changes in snus use are similar to prior smoking epidemic development.

Methods
The study was based on the 2010 (n = 5836), 2014 (n = 13,319) and 2018 (n = 24,515) waves from a nation-wide, cross-sectional, health survey of higher education in Norway (the SHoT study). Variables on smoking, snus use, gender, age and SES were used. Chi-square tests and logistic regression analyses were used to test significance, and Mantel–Haenszel weights were used to test the trends in stratified cross-tabulations.

Results
Daily smoking decreased from 5.9 to 1.5% between 2010 and 2018, while daily snus use increased from 13.4 to 19.9%. Female snus use almost doubled, from 10.9 to 19.2%. Low SES was associated with both daily smoking and snus use across all three waves. Occasional smoking was also associated with low SES at all waves, but occasional snus use was only associated with low SES in 2010. There were no significant changes over time in either the association between occasional or daily smoking and SES or the association between occasional or daily snus use and SES.

Conclusions
The overall smoking decrease indicated that the Norwegian smoking epidemic is in its latest stage. Steady male snus use, doubled female snus use and a clear social gradient in snus use all indicate that the snus epidemic in Norway has progressed. If this trend continues, a main implication is that snus prevalence will soon peak, first in males and then in females.
Acceptability of a cessation intervention for pregnant smokers: a qualitative study guided by Normalization Process Theory
Authors: Jones Susan E. , Hamilton Sharon , Bell Ruth , Araújo-Soares Vera , White Martin 
Published: October 2020

Abstract
Background
Smoking during pregnancy has serious consequences for maternal and child health. An intervention package to embed National Institute for Health and Care Excellence guidance (babyClear©) was delivered across maternity and stop smoking services (SSS) within an English region, to support pregnant women to stop smoking. We aimed to ascertain acceptability among pregnant smokers receiving the intervention.

Methods
Pregnant smokers who received the intervention and participated in the study were interviewed, first at around 16 weeks of pregnancy (n = 17) and again several weeks later (n = 8) or postpartum (n = 3). Interview schedules were informed by Normalization Process Theory (NPT) and Theoretical Domains Framework; interviews were audio-recorded, transcribed and analysed thematically, using the Framework method and NPT. Findings are grouped according to the four NPT concepts.

Results
Coherence: Carbon monoxide monitoring appeared to make sense; women were motivated to quit by being monitored. Cognitive participation: When linked to a professional discourse of caring and concern, some women were prompted to engage with the SS message. Women were more guarded in their reaction to initial contact from the SSS; reporting attending appointments successfully, or in some cases, experiencing problems that decreased engagement and made quitting harder. Collective action: Where women continued to smoke or failed to attend SSS appointments, an extra intervention was delivered, the Risk Perception Tool (RPT), which often prompted pregnant women to act. Reflexive monitoring: Most women accepted the need for a hard-hitting approach (RPT) and, while it distressed them at the time, they claimed they were subsequently grateful for it. SSS intervention post-RPT was seen as supportive, partly because it often involved home visits. Aspects of family inclusion in babyClear© were reported as beneficial. In Trusts where women experienced services as less focused on prioritising the stop smoking message, less well integrated or reported maternity staff as less adept at delivering the RPT, women found babyClear© less acceptable overall.

Conclusions
The babyClear© package was acceptable to pregnant smokers interviewed during and shortly after pregnancy and, in some cases, to promote quitting. However, some contexts were more optimal than others, leading to variation in acceptability overall.
Why crowding matters in the time of COVID-19 pandemic? - a lesson from the carnival effect on the 2017/2018 influenza epidemic in the Netherlands
Authors:   LUMC-COVID-19 Research Group, Chen Qingui , Toorop Myrthe M. A. , de Boer Mark G. J. , Rosendaal Frits R. , Lijfering Willem M. 
Published: October 2020

Abstract
Background
To evaluate the association between crowding and transmission of viral respiratory infectious diseases, we investigated the change in transmission patterns of influenza and COVID-19 before and after a mass gathering event (i.e., carnival) in the Netherlands.

Methods
Information on individual hospitalizations related to the 2017/2018 influenza epidemic were accessed from Statistics Netherlands. The influenza cases were stratified between non-carnival and carnival regions. Distributions of influenza cases were plotted with time and compared between regions. A similar investigation in the early outbreak of COVID-19 was also conducted using open data from the Dutch National Institute for Public Health and the Environment.

Results
Baseline characteristics between non-carnival and carnival regions were broadly similar. There were 13,836 influenza-related hospitalizations in the 2017/2018 influenza epidemic, and carnival fell about 1 week before the peak of these hospitalizations. The distributions of new influenza-related hospitalizations per 100,000 inhabitants with time between regions followed the same pattern with a surge of new cases in the carnival region about 1 week after carnival, which did not occur in the non-carnival region. The increase of new cases for COVID-19 in the carnival region exceeded that in the non-carnival region about 1 week after the first case was reported, but these results warrant caution as for COVID-19 there were no cases reported before the carnival and social measures were introduced shortly after carnival.

Conclusion
In this study, a mass gathering event (carnival) was associated with aggravating the spread of viral respiratory infectious diseases.
Spirometry practice and the impact of a phase 1 training workshop among health workers in southern Nigeria: a cross-sectional study
Authors: Ayuk Adaeze , Ndukwu Chizalu , Uwaezuoke Samuel , Ekop Eno 
Published: October 2020

AbstractBackgroundGlobal standards require that spirometry should be performed by trained and experienced personnel, who would be able to assess the correct performance of tests by patients and assure good quality of the result. The complete achievement of this requires a two-step assessment where competency in both knowledge and skills are tested. This study aims to assess the impact of a one-day hands-on spirometry training (Phase1), on the knowledge and application of spirometry among health workers.MethodsThis was a descriptive cross-sectional study, which describes a one-day (seven hours) spirometry training and skills impartation done at two conference city locations in Enugu and Calabar in the southern part of Nigeria. All the verbally consenting attendees who completed the training assessment tests constituted the study population. The assessment of the spirometry knowledge base before and after the theory and practical sessions, on the various aspects of spirometry, according to international best practices, quality assurance and the interpretation of results, was done and the outcome was analyzed. Factors that could affect the outcome were also assessed.ResultsThere were 64 consenting participants of whom 54.7% (35/64) were females. Theparticipants demonstrated much improved post-intervention knowledge and could satisfactorily perform spirometry, calibration, interpretation of test results and quality control as evidenced by the post test scores after practical sessions were conducted. Pre-test mean scores improved by a mean difference of 12% (p < 001) and were affected by the year of academic graduation and availability of spirometers at the place of work, an effect that was no longer seen at post-test following the hands-on spirometry training.ConclusionThe present study has shown that a one-day spirometry workshop significantly improved the knowledge of spirometry practice. There is need to set up more frequent locally-organized spirometry workshops since a one-day seven-hour effective knowledge and practical training would most likely have significant impact on participants’ spirometry practice with its expected positive outcome on respiratory health in Nigeria.
Peri-acetabular bone remodelling after uncemented total hip arthroplasty with monoblock press-fit cups: an observational study
Authors: Anderl Conrad , Mattiassich Georg , Ortmaier Reinhold , Steinmair Martin , Hochreiter Josef 
Published: October 2020

AbstractBackgroundBone stock preservation in total hip replacement is essential to allow for later revisions in an increasingly younger and fitter index patient population. While contemporary modular press-fit acetabular cups lead to rigid fixation with equatorial stress and central osteolysis, more elastic fixation may cause different peri-acetabular bone remodelling. The purpose of this study was to investigate changes in peri-acetabular bone mineral density (BMD) in uncemented elastic fixation with monoblock press-fit cups.MethodsThis prospective observational study included 45 patients with monoblock cups. We evaluated peri-acetabular BMD using dual-energy X-ray absorptiometry and reported functional outcomes and complications.ResultsAt a mean follow-up of 24.2 ± 2.2 months, we found that BMD stabilised in DeLee and Charnley zones I and III and recovered to baseline value in zone II. The mean Harris Hip Scores improved significantly from 56.9 ± 20.0 to 97.2 ± 4.0 (p <  0001). Other than one peri-operative dislocation, we saw no post-operative complications.ConclusionsWe found favourable adaptive bone changes with BMD stabilisation in the equatorial zones and recovery to pre-operative values in the central zone. Additionally, excellent clinical outcomes and few prosthesis-related complications strengthened the favourable results of monoblock acetabular cups.Trial registrationRegistration number DRKS00017076.
Does the IOFix implant improve union rates?
Authors: Segal David , Ohana Nissim , Nyska Meir , Palmanovich Ezequiel 
Published: October 2020

Abstract
Background
First metatarso-phalangeal joint fusion is the current gold standard for severe hallux rigidus. Data regarding the union rate and the re-operation rate when IOFix (an Intra-osseous fixation device, Extremity medical, New Jersey, USA) is used for hallux rigidus fusion is limited but promising. The aim of this study was to review our outcomes with the IOFix implant.

Methods
We have conducted a retrospective chart review, following the approval of the hospital IRB committee. Exclusion criteria included bilateral operations on the same patient, multiple surgeries, charcot foot or other structural foot abnormalities (except hallux valgus), rheumatoid arthritis and a recent foot trauma. We collected demographic data, physical examination documentation, functional score evaluations (AOFAS), and Plain radiographic studies.

Results
Thirty patients were included in the study. The mean age was 60.36 ± 9.12 (range 36 to 77) years, 18 (60%) female patients and 12 (40%) male. Fourteen (53.33%) were left side pathologies. The average follow up period was 36.2 ± 12.31 (range 12 to 54) months. Union was obtained in 28 (93.33%) patients, of whom none had requested a hardware removal due to a prominent hardware during a minimum of 2 year follow up period. The mean postoperative AOFAS score was 80.5 ± 10.87 (range 35 to 90). A more stringent inclusion criteria and fusion definitions would have led to an exclusion of two more patients and a dropout of two patients from the “fused” group, which would have led to a fusion rate of 85.71%.

Conclusions
This is the largest series of hallux rigidus patients that were operated with an IOFix device. The rates of fusion and hardware removal in MTPJ1 arthrodesis performed with an IOFix implant were found to be similar at most when compared to previously described rates that were obtained with other cheaper and more simple fixation devices.

Designing a Mission statement Mobile app for palliative care: an innovation project utilizing design-thinking methodology
Authors: Kamran Rakhshan , Dal Cin Arianna 
Published: October 2020

Abstract
Background
Eliciting individual values and preferences of patients is essential to delivering high quality palliative care and ensuring patient-centered advance care planning. Despite advance care planning conserving healthcare costs by up to 36%, reducing psychological distress of patients and caregivers, and ensuring palliative care delivery in line with patient wishes, less than 33% of adults engage in it. We aimed to develop a mobile application intervention to address the challenges related to advance care planning and improve the delivery of palliative care.

Methods
Design-thinking methodology was used to develop a mobile application, in response to issues prominently identified in current palliative care literature.

Results
Issues surrounding communication of patient values from both the patient and provider side is identified as a main issue in palliative care. We designed a mobile application intervention prototype to address this.

Conclusions
Our “Mission Statement” mobile application will allow patients to create a mission statement identifying what they want their care team to know about them, as well as space to identify important values and preferences. Patients will be able to evolve their mission statement and values and preferences over the course of their palliative care journey through the application. Design-thinking methodology is an effective tool to drive healthcare innovation and bridge the gap between research findings and implementation.
Prevalence and determinants of unmet need for contraception in North Gonja District, Ghana

Published: October 2020

Abstract
Background
Unmet need for contraception contributes to the burden of unwanted pregnancies, which are correlated with a host of adverse maternal and child outcomes. The aim of this study was to determine the prevalence and identify the determinants of unmet need for contraception in North Gonja District, Ghana.

Methods
A cross-sectional survey involving 386 randomly selected women of childbearing age was conducted in North Gonja district, Ghana, with the use of a questionnaire in household interviews. Women were classified as having unmet need for contraception if they were fecund, sexually active and wished to postpone the next birth or halt childbearing completely but were not using any form of contraception. Chi-square/Fisher’s exact test and logistic regression analysis were used to identify the determinants of unmet need.

Results
The mean age of the study population was 26.1 (±8.4) years and awareness on contraception was almost universal in the district (95.9%). The overall prevalence of unmet need for contraception was 38.9%, with 27.5% having unmet need for limiting and 12.2% unmet need for spacing. In multivariate analysis, compared to women aged 25–29 years, those aged 20–24 years [Adjusted Odds Ratio (AOR) 0.26; 95% Confidence Interval (CI) 0.11–0.58] and 30 years and above (AOR 0.25; 95% CI 0.09–0.73) were less likely to have unmet need for contraception. However, uneducated women (AOR 5.06; 95% CI 1.07–24.01) compared with those educated to tertiary level; those unaware of family planning (AOR 3.93; 95% CI 1.12–13.80) compared to those aware; and those who had not previously practised contraception (AOR 1.81; 95% CI 1.09–3.00) compared to those who did were more likely to have unmet need.

Conclusions
The present study found high prevalence of both awareness on and unmet need for contraception among the study population. Unmet need for contraception is associated with age, educational status, awareness on family planning and previous contraception practice. Educational campaigns to promote contraception should prioritize women of middle age and low educational status. Further studies are needed to understand the low correlation between awareness on and unmet need for contraception.
