AbstractBackgroundChronic malnutrition, often measured as stunted growth, is an understudied global health problem. Though poor nutritional intake has been linked to stunted growth, there is evidence suggesting environmental exposures may have a significant role in its occurrence. Here, we characterize the non-nutritional prenatal and postnatal factors that contribute to early childhood stunted growth in rural coastal Kenya.MethodsOverall, 232 women and 244 children from a 2012–2015 maternal-child cohort in Msambweni, Kenya were included. Women were tested for parasitic infections during the prenatal period and at the time of delivery. Children were tested for parasitic infections and assessed for stunted growth using height-for-age Z-scores (HAZ) at 6-month intervals after birth. Socioeconomic status (SES) was evaluated using both a simplified water, asset, maternal education, and income (WAMI) index and a principal component analysis (PCA) asset score. Multivariate logistic regression analysis was used to determine the relative influence of prenatal and postnatal factors on the occurrence of stunted growth.ResultsOf the 244 children (ages 6–37 months), 60 (25%) were stunted at the study endpoint. 179 mothers (77%) had at least one parasitic infection during pregnancy and 94 children (38%) had at least one parasitic infection during the study period. There was no significant association between maternal parasitic infection and child stunted growth (p = 1.00). SES as determined using the WAMI index was not associated with HAZ in linear regression analysis (p = 0.307), however, the PCA asset score was (p = 0.048). Multivariate logistic regression analysis identified low birth weight (AOR: 3.24, 95% CI: [1.38, 7.57]) and child parasitic infectious disease burden (AOR: 1.41, 95% CI: [1.05, 1.95]) as independent predictors of stunted growth, though no significant association was identified with PCA asset score (AOR: 0.98, 95% CI: [0.88, 1.10]).ConclusionsStunted growth remains highly prevalent in rural Kenya, with low birth weight and child parasitic infectious disease burden demonstrated to be significantly associated with this indicator of chronic malnutrition. These results emphasize the multifaceted nature of stunted growth and the need to address both the prenatal and postnatal environmental factors that contribute to this problem.

Abstract
Background
Data on intensive care unit (ICU) related psychiatric morbidity from Low Middle-Income Countries are sparse. We studied the ICU related posttraumatic stress symptoms (PTSS), anxiety, and depression symptoms in a cohort of patients from Eastern India.

Methods
We included adults admitted more than 24 h to a mixed ICU. PTSS, anxiety, and depression symptoms were assessed by telephonic or face to face interviews by using the Impact of Events-r (IES-r) and Hospital anxiety and depression (HADS), respectively, at 0, 7,14, 30, 90 and 180 days from ICU discharge. The loss to follow up was minimal. Demographic, socioeconomic, quality of life (QOL), and critical care related variables were studied.

Results
Of 527 patients, 322 (59.4%) completed 6 months’ follow up. The majority were male (60%), mechanically ventilated > 48 h (59.4%), mean age of 48 (+/− 16), mean acute physiology and chronic health evaluation II (APACHE II) at admission 9.4 (+/− 4.6), median length of stay 3 (2–28 days). The rates of ICU related clinical PTSS was < 1 and < 3% for anxiety/depression at any point of follow up. Data were analyzed by linear mixed (random effects) models. There was a significant drop in all scores and association with repeated measures over time. Poor QOL at discharge from the ICU showed significant association with PTSS, anxiety, and depression (β = − 2.94, − 1.34, − 0.7 respectively) when corrected for gender and education levels. Younger age, greater severity of illness, and prior stressful life experiences predicted worse PTSS (β = − 0.02, 0.08, 3.82, respectively). Benzodiazepines and lower sedation scores (better alertness) predicted lower depression symptoms. (β = − 0.43, 0.37 respectively).

Conclusion
ICU related psychiatric morbidity rates in our population are low compared with reported rates in the literature. Poor QOL at ICU discharge may predict worse long-term mental health outcomes. Further research on the impact of ICU and sociocultural factors on mental health outcomes in patients from different backgrounds is needed. The study was registered at CTRI/2017/07/008959.
Vaccination card availability and childhood immunization in Senegal
Authors: Seror Valérie , Cortaredona Sébastien , Ly Elhadji Yaya , Ndiaye Samba , Gaye Ibrahima , Fall Mouhamadou , Peretti-Watel Patrick 
Published: May 2020

Abstract
Background
The World Health Organization recommends recording vaccination status according to maternal recall in countries where administrative reporting systems are insufficiently reliable, as maternal recall in developing countries has been shown to be quite reliable compared with data from vaccination cards. This study aimed to investigate childhood vaccination coverage and its determinants according to the mothers’ presentation of vaccination cards.

Methods
The data come from the 2017 Senegalese Demographic and Health Survey, a nationally representative household survey of women aged 15–49 years, with a questionnaire focusing on children’s health. This analysis was restricted to children aged 12–35 months (n = 4032) and it assessed vaccination coverage and associated sociodemographic factors with weighted multivariate logistic regressions. Stratified multivariate logistic regressions were also performed to investigate factors associated with routine childhood immunization uptake of the Bacillus Calmette-Guérin (BCG) vaccine, recommended for administration shortly after birth, as well as of the vaccines against yellow fever and measles (recommended at 9 months).

Results
Comparison of vaccination coverage estimates according to the vaccination card or parental recall resulted in a 5–10% difference in estimated coverage for the BCG, pentavalent, measles, and yellow fever vaccines, but a huge difference for the polio vaccine (93.0% with the card, 32.0% without it). Presentation of the vaccination card was correlated with mothers’ attendance at health facilities (suggesting it serves as a concrete manifestation of a bond between mothers and the healthcare system) and their region of residence, but it was not correlated with usually strong predictors of childhood vaccination, such as maternal education level. Factors associated with vaccinations differed depending on whether they were administered shortly after birth or later on.

Conclusions
Maternal recall was found to be quite reliable except for oral polio vaccination, which raises the possibility that complete immunization coverage rates could have been significantly underestimated due to potential confusion between injection and vaccination. Considering the ability to present vaccination cards as the materialization of a bond with the healthcare system, the decision path leading to vaccination among those who lack such a bond appears longer and more likely to be driven by supply-side effects.

Published: May 2020

Abstract
Background
Non-Communicable Diseases (NCD) are the leading cause of death in the Pacific Island Countries and Territories (PICTs) accounting for approximately 70% of mortalities. Pacific leaders committed to take action on the Pacific NCD Roadmap, which specifies NCD policy and legislation. To monitor progress against the NCD Roadmap, the Pacific Monitoring Alliance for NCD Action (MANA) was formed and the MANA dashboard was developed. This paper reports on the first status assessment for all 21 PICTs.

Methods
The MANA Dashboard comprises 31 indicators across the domains of leadership and governance, preventive policies, health system response and monitoring processes, and uses a ‘traffic light’ rating scheme to track progress. The dashboard indicators draw on WHO’s best-buy interventions and track highly cost-effective interventions for addressing NCDs. The MANA coordination team in collaboration with national NCD focal points completed Dashboards for all 21 PICTs between 2017 and 2018 in an agreed process. The data were analysed and presented within each area of the MANA dashboard.

Results
This assessment found that PICTs are at varying stages of developing and implementing NCD policy and legislation. Some policy and legislation are in place in most PICTs e.g. smoke free environment (18 PICTs), alcohol licensing (19 PICTs), physical education in schools (14 PICTs), reduction of population salt consumption (14 PICTs) etc. However, no PICTs has policy or legislation on tobacco industry interference, controlling marketing of foods and drinks to children, and reducing trans-fats in the food supply, and only 7 PICTs have policies restricting alcohol advertising. Eighteen PICTs implement tobacco taxation measures, however only five were defined as having strong measures in place. Nineteen PICTs have alcohol taxation mechanisms and 13 PICTs have fiscal policies on foods to promote healthier diets.

Conclusion
This baseline assessment fills a knowledge gap on current strengths and areas where more action is needed to scale up NCD action in a sustained ‘whole of government and whole of society approach’ in PICTs. The findings of this assessment can be used to identify priority actions, and as a mutual accountability mechanism to track progress on implementation of NCD policy and legislation at both national and Pacific level.
“To die is better than to tell”: reasons for and against disclosure of chronic hepatitis B status in Ghana
Authors: Adjei Charles Ampong , Stutterheim Sarah E. , Naab Florence , Ruiter Robert A. C. 
Published: May 2020

Abstract
Background
People with a condition subject to stigmatisation, such as chronic hepatitis B, face the dilemma of whether or not to disclose their status. In Ghana, 12.3% of the adult population has the hepatitis B virus (HBV). One key strategy for breaking the cycle of hepatitis B transmission is the disclosure of hepatitis B status by people with chronic hepatitis B (PWHB). Disclosure can facilitate preventive actions to reduce hepatitis B transmission (e.g., not sharing personal items and avoiding contact with blood and body fluids). Disclosure can also motivate family members of PWHB to get tested, linked to care and clinically managed in order to reduce the progression of hepatitis B to liver cirrhosis and cancer. Given the importance of disclosure, we set out to explore reasons for and against disclosure of chronic hepatitis B status in the Greater Accra and Upper East region of Ghana.

Methods
In this exploratory qualitative study, 18 participants (10 from the Greater Accra region and 8 from the Upper East region) were recruited for semi-structured interviews. Interviews were recorded and transcribed verbatim. Data were then processed using QSR Nvivo version 10.0 and analysed for themes.

Results
Participants were selective disclosers, disclosing in some contexts and not in others. Reasons for non-disclosure of chronic hepatitis B status were: 1) fear of stigmatisation and 2) previous negative experiences with disclosure. Reasons for disclosure were: 1) wanting close contacts to get tested or vaccinated, 2) trusting the disclosure target(s), and 3) needing social and/or financial support.

Conclusions
Our findings highlight various reasons for and against disclosure of chronic hepatitis B status in Ghana. Because anticipated, observed, and experienced stigma were important motivations for non-disclosure of chronic hepatitis B status, we recommend the development and implementation of theory and evidence-based stigma reduction interventions that are culturally appropriate, and that prioritize the participation of target populations. We also recommend the provision of counselling and support services that assist PWHB in their disclosure decision-making processes.

Abstract
Background
China has the world’s largest lesbian, gay, bisexual, and transgender (LGBT) population. This study assessed the discrimination experienced by LGBT individuals in China in a comprehensive way, covering discrimination perpetrated by family, media, medical services, religious communities, schools, social services, and in the workplace.

Methods
The current study involved a national survey of 31 provinces and autonomous regions. Discrimination was measured both in terms of heterosexual participants’ attitudes towards LGBT individuals, and LGBT participants’ self-perceived discrimination. Pearson correlation analysis was performed to examine the difference between heterosexual participants’ attitudes towards LGBT individuals and LGBT participants’ self-perceived discrimination. Linear regression was used to investigate the association between gross domestic product per capita and discrimination.

Results
Among 29,125 participants, 2066 (7.1%) identified as lesbian, 9491 (32.6%) as gay, 3441 (11.8%) as bisexual, 3195 (11.0%) as transgender, and 10,932 (37.5%) as heterosexual. Heterosexual people were generally friendly towards the LGBT community with a mean score of 21.9 (SD = 2.7, total scale score = 100) and the grand averaged score of self-perceived discrimination by LGBT participants was 49.9 (SD = 2.5). Self-perceived discrimination from family and social services is particularly severe. We created a series of provincial level choropleth maps showing heterosexual participants’ acceptance towards the LGBT community, and self-perceived discrimination reported by members of the LGBT community. We found that a higher level of economic development in provinces was associated with a decrease in discrimination, and we identified that every 100 thousand RMB increase in per capita GDP lead to a 6.4% decrease in discriminatory events perpetrated by heterosexuals.

Conclusions
Chinese LGBT groups consistently experience discrimination in various aspects of their daily lives. The prevalence of this discrimination is associated with the economic development of the province in which it occurs. In order to reduce discrimination, it is important for future studies to discover the underlying reasons for discrimination against LGBT individuals in China.
Epidemiology of laboratory-confirmed mumps infections in South Africa, 2012–2017: a cross-sectional study
Authors: Sikhosana Mpho Lerato , Kuonza Lazarus , Motaze Nkengafac Villyen 
Published: May 2020

Abstract
Background
Data on the burden of mumps in South Africa are limited and the epidemiology of mumps in this setting is not well understood. We present an analysis of mumps data in South Africa from 2012 to 2017.

Methods
This cross-sectional study included secondary data on laboratory-confirmed mumps infections from 2012 to 2017, archived at the South African National Health Laboratory Services’ data repository as well as from four private laboratories. Mumps-specific immunoglobulin M (IgM) and/or viral nucleic acid positive results represented acute infections. We used age-specific mid-year population estimates for each study year as denominators when calculating annual cumulative incidence. Seasonality was based on the season that showed a peak in infections.

Results
Out of 48,580 records obtained from the public and private sectors, 46,713 (96.2%) were from the private sector. Over the study period, there were 7494 acute infections, 7085 (94.5%) of which were recorded in the private sector. Of these 7494 infections, 3924 (52.4%) occurred in males. The proportion of samples tested that were IgM positive was 18.6% (1058/5682) in 2012, 15% (1016/6790) in 2013, 15.8% (1280/8093) in 2014, 15.5% (1384/8944) in 2015, 13.1% (1260/9629) in 2016 and 15.8% (1496/9442) in 2017. The cumulative incidence rate per 100,000 was highest in children between one and 9 years throughout the study period. The cumulative incidence of infections was highest in the Western Cape, Gauteng and the Northern Cape. Infections peaked in June and November.

Conclusion
Laboratory-confirmed mumps infections predominantly occurred in spring, affecting children below 10 years of age and individuals who were male. There were fewer tests performed in the public sector compared to the private sector. Since only laboratory data was analysed our results represent and underestimate of disease burden. Further studies that include clinical data are required to provide better estimates of disease burden in South Africa.

Published: May 2020

AbstractBackgroundStemless total shoulder arthroplasty is a well-established and reliable surgical treatment option for glenohumeral osteoarthritis resulting in loss of pain and improvement of shoulder function. Currently the two methods for the fixation of the humeral component are either screw fixation or impaction. The purpose of this study is the clinical and radiological comparison of two different stemless designs (screw fixation vs impaction) for total shoulder arthroplasties in patients suffering from primary glenohumeral osteoarthritis.MethodsA retrospective cohort study including 39 patients with a mean age of 67 years and a minimum follow-up of 2 years was performed. Patients were separated into two groups based on the selected implant. In group A (n = 18) a screw fixation design and in group B (n = 21) an impaction type design was used. For clinical examination the Constant-Murley-Score (CS) and Subjective-Shoulder-Value (SSV) were evaluated. Radiological examination was performed on true-AP, axial and Y-view radiographs.ResultsIn group A the CS increased from 27.1 to 65.2 points and SSV from 27.3 to 76.7% (p < 0.05). No osteolysis of the medial calcar or subsidence of the humeral implant were found in this group. In group B the CS increased from 29.0 to 72.6 points and SSV from 33.1 to 85% (p < 0.05). Osteolysis of the medial calcar was present in seven patients in this group. No signs for humeral loosening were found in both groups.ConclusionImpaction and screw fixation total shoulder arthroplasty for primary glenohumeral osteoarthritis using a stemless device provide reliable clinical results. The screw fixation seems to prevent osteolysis of the medial calcar.
Matrix metalloproteinases gene variants and dental caries in Czech children
Authors: Borilova Linhartova Petra , Deissova Tereza , Kukletova Martina , Izakovicova Holla Lydie 
Published: May 2020

Abstract
Background
Matrix metalloproteinases (MMPs) play an important role in tooth formation and the mineralization of dental tissue. The aim of the study was to analyse Czech children with primary/permanent dentition polymorphisms in those genes encoding MMP2, MMP3, MMP9, MMP13, MMP16, and MMP20, which had been previously associated with dental caries in other populations.

Methods
In total, 782 Czech children were included in this case-control study. DNA samples were taken from 474 subjects with dental caries (with decayed/missing/filled teeth, DMFT ≥ 1) and 155 caries free children (DMFT = 0) aged 13–15 years, as well as 101 preschool children with early childhood caries (ECC, dmft ≥ 1) and 52 caries free children (dmft = 0), were analyzed for nine MMPs single nucleotide polymorphisms (SNPs) using real time polymerase chain reaction TaqMan assays.

Results
There were no significant differences in the allele and/or genotype frequencies of all the studied MMPs SNPs among children with dental caries in primary/permanent dentition and the healthy controls (P > 0.05). In addition, similar allele or genotype frequencies of the studied MMPs SNPs were found in children with severe dental caries in their permanent teeth (children with DMFT ≥ 6) and the healthy controls (DMFT = 0, P > 0.05).

Conclusions
This study demonstrated the lack of association between the selected SNPs in candidate genes of MMPs and the susceptibility to or severity of dental caries in both primary and permanent dentitions in Czech children.

Published: May 2020

Abstract
Background
While the importance of medical students’ demographic characteristics in influencing the scope and location of their future practice is recognized, these data are not systematically collected in Canada. This study aimed to characterize and compare the demographics of Canadian medical students with the Canadian population.

Methods
Through an online survey, delivered in 2018, medical students at 14 English-speaking Canadian medical schools provided their age, sex, gender identity, ethnicity, educational background, and rurality of the area they grew up in. Respondents also provided information on parental income, occupation, and education as markers of socioeconomic status. Data were compared to the 2016 Canadian Census.

Results
A total of 1388 students responded to the survey, representing a response rate of 16.6%. Most respondents identified as women (63.1%) and were born after 1989 (82.1%). Respondents were less likely, compared to the Canadian Census population, to identify as black (1.7% vs 6.4%) (P < 0.001) or Aboriginal (3.5% vs. 7.4%) (P < 0.001), and have grown up in a rural area (6.4% vs. 18.7%) (P < 0.001). Respondents had higher socioeconomic status, indicated by parental education (29.0% of respondents’ parents had a master’s or doctoral degree, compared to 6.6% of Canadians aged 45–64), occupation (59.7% of respondents’ parents were high-level managers or professionals, compared to 19.2% of Canadians aged 45–64), and income (62.9% of respondents grew up in households with income >$100,000/year, compared to 32.4% of Canadians). Assessment of non-response bias showed that our sample was representative of all students at English-speaking Canadian medical schools with respect to age, though a higher proportion of respondents were female. Additionally, there were no differences between early and late respondents with respect to ethnicity, rurality, and parental income, occupation, and education.

Conclusions
Canadian medical students have different socioeconomic characteristics compared to the Canadian population. Collecting and analyzing these characteristics can inform evidence-based admissions policies.
